MERGER PROPOSAL
YOUR VOTE IS VERY IMPORTANT
[    ], 2004
Dear Shareholders,

     Mylan Laboratories Inc., Summit Merger Corporation (Mylan’s wholly-owned subsidiary) and King Pharmaceuticals, Inc. have entered into a merger agreement, pursuant to which Mylan will acquire King and King shareholders will receive 0.9 shares of Mylan common stock for each share of King common stock they own, plus cash in lieu of fractional shares. We are proposing the merger because we believe it represents a strategic combination that will unite two highly complementary businesses to form one of the nation’s leading specialty pharmaceutical companies based on the number of prescriptions dispensed in the U.S. The boards of directors of Mylan and King believe the merger is strategically and financially beneficial to Mylan and King, and will create a stronger, well-diversified pharmaceutical company with the potential to create significant value for shareholders.

     A special meeting of Mylan shareholders will be held at [                  ], on [                  ], 2004 at [                  ], local time, to vote on the issuance of shares of Mylan common stock to King shareholders pursuant to the merger and to transact any other business that may properly be brought before the Mylan special meeting or any adjournments or postponements thereof.

     A special meeting of King shareholders will be held at [                  ], on [                  ], 2004, at [                  ], local time, to vote on the approval and adoption of the merger agreement and approval of the merger and to transact any other business that may properly be brought before the King special meeting or any adjournments or postponements thereof.

     Each of Mylan’s and King’s board of directors has unanimously (with one director absent in the case of King) approved the proposed merger and approved and adopted the merger agreement. Mylan’s board has also unanimously approved the issuance of Mylan common stock to King shareholders pursuant to the merger. Accordingly,

  •  the Mylan board recommends that Mylan shareholders vote “FOR” the proposal to approve the issuance of Mylan common stock to King shareholders pursuant to the merger, and
 
 
  •  the King board recommends that King shareholders vote “FOR” the proposal to approve and adopt the merger agreement and approve the merger.

     Based on the number of shares of Mylan and King common stock outstanding as of the applicable record dates, immediately after the merger current Mylan shareholders collectively will own approximately [56]% of the outstanding shares of the combined company and King shareholders collectively will own approximately [44]% of the outstanding shares of the combined company. We estimate that Mylan will issue approximately [217.3] million shares of Mylan common stock in the merger and will reserve an additional approximately [12.2] million shares of Mylan common stock for future issuances upon the exercise of outstanding options to purchase King common stock and conversion of King’s convertible debentures. It is a condition to the completion of the merger that the New York Stock Exchange, which is referred to as the NYSE, authorize for listing the shares of Mylan common stock to be issued in connection with the merger and the conversion of King stock options.

     The dollar value of the shares of Mylan common stock that King shareholders receive in the merger will change depending on changes in the market price of Mylan common stock. Mylan’s common stock is traded on the NYSE, under the symbol “MYL.” On September 2, 2004, the last sale price of Mylan’s common stock prior to the date of this document, as reported on the NYSE Composite Transactions Tape, was $17.44 per share.

     We expect that the merger will qualify as a “tax-free” reorganization and that King shareholders will not recognize gain or loss in connection with the merger, except for the taxes on cash received by King shareholders in lieu of receiving fractional shares of Mylan common stock.

     Your vote is very important, regardless of the number of shares you own. Please take the time to vote (in writing, over the Internet or by telephone) by following the instructions on your proxy card or, if your shares are held in the name of a bank or broker, please instruct your bank or broker on how to vote. If you are a Mylan shareholder and do not vote or do not instruct your broker or bank on how to vote, it will have no effect on the proposal to approve the issuance of shares of Mylan common stock to King shareholders pursuant to the merger, because only those votes cast “FOR” or “AGAINST” the proposal will be counted. If you are a King shareholder and do not vote or do not instruct your broker or bank on how to vote, it will have the same effect as voting against the merger. The accompanying materials provide details on the Mylan and King special meetings, and explain the merger and the issuance of the shares of Mylan common stock pursuant to the merger agreement.

  Sincerely,

QUESTIONS AND ANSWERS

      The following are some questions that you, as a shareholder of Mylan or King, may have regarding the merger and the answers to those questions. Mylan and King urge you to read carefully the remainder of this joint proxy statement/ prospectus because the information in this section does not provide all the information that might be important to you with respect to the merger and the issuance of Mylan common stock to King shareholders pursuant to the merger. Additional important information is also contained in the annexes to and the documents incorporated by reference in this joint proxy statement/ prospectus.

Q: Why am I receiving this joint proxy statement/ prospectus?

A:  The boards of directors of each of Mylan and King have agreed to the combination of King with Mylan under the terms of a merger agreement that is described in this joint proxy statement/ prospectus. A copy of the merger agreement is attached to this joint proxy statement/ prospectus as Annex A.

To complete the merger, Mylan shareholders must approve the issuance of shares of Mylan common stock to King shareholders pursuant to the merger, King shareholders must approve and adopt the merger agreement and approve the merger, and all other conditions of the merger must be satisfied or waived.

Mylan and King will hold separate shareholders’ special meetings to obtain these approvals. This joint proxy statement/ prospectus contains important information about the merger and the special meetings of the respective shareholders of Mylan and King, and you should read it carefully. The enclosed voting materials allow you to vote your shares without attending your respective shareholders’ special meeting.

Your vote is important. We encourage you to vote as soon as possible.

Q: What will happen in the merger?

A:  A direct, wholly-owned subsidiary of Mylan will merge with and into King. At the completion of the merger, Summit Merger Corporation, a direct, wholly-owned subsidiary of Mylan formed for the purposes of the merger, will be merged with and into King, and King shareholders will receive 0.9 shares of Mylan common stock for each share of King common stock they own, plus cash in lieu of fractional shares. Based on the number of shares of Mylan and King common stock outstanding as of the applicable record dates, we estimate that Mylan will issue approximately [217.3] million shares of common stock in the merger and that, immediately after the merger, the former King shareholders, in the aggregate, will own approximately [44]% of the then-outstanding shares of Mylan common stock.

Upon completion of the merger, each outstanding option to purchase King common stock under a King stock option plan will be assumed by Mylan and will become an option to purchase, generally on the terms and conditions as were applicable under the King option, shares of Mylan common stock. The number of shares of Mylan common stock subject to each stock option and the per share exercise price of each stock option will be adjusted based on the exchange ratio.

Q:  Why are Mylan and King proposing this merger?

A:  After careful consideration, the Mylan board unanimously determined that the merger is fair and in the best interests of Mylan and its shareholders and the King board unanimously (with one director absent) determined that the merger is fair and in the best interests of King and its shareholders. The boards of each of Mylan and King unanimously (with one director absent in the case of King) approved and adopted the merger agreement and approved the merger, and the transactions contemplated thereby. For a description of the factors considered by the board of directors, please refer to the sections of this joint proxy statement/ prospectus entitled “The Merger — Mylan’s Reasons For the Merger” and “The Merger — King’s Reasons For the Merger” beginning on page 35 and page 44, respectively.

For a description of the reasons underlying the recommendation of the King board of directors with respect to the merger, please refer to the section of this joint proxy statement/ prospectus entitled “The Merger — King’s Reasons For the Merger” beginning on page 44.
 
Q: What vote of King shareholders is required to approve and adopt the merger agreement and approve the merger?
 
A: The adoption and approval of the merger agreement and approval of the merger requires the affirmative vote of a majority of all the votes entitled to be cast on such proposal. For a more complete description of voting, please refer to the section of this joint proxy statement/ prospectus entitled “The King Special Meeting” beginning on page 97.
 
Q: Will the Mylan stock issued to King shareholders pursuant to the merger be listed?

official notice of issuance. Mylan has agreed to use its reasonable best efforts to cause those shares of Mylan common stock to be authorized for listing on the NYSE.
 
Q: How do I vote?
 
A: There are four different ways you may cast your vote. If you are a shareholder of record as of the applicable record date you may vote:

• in person by attending your shareholders’ special meeting,

• by accessing the Internet website specified on your enclosed proxy card,

• by calling the telephone number specified on your proxy card, or

• by completing, signing and dating your proxy card and returning it in the postage-paid envelope provided.

If you vote over the Internet or by telephone, you must do so before 11:59 p.m., Eastern time, on [                    ], the day before the Mylan special meeting or before 11:59 p.m., Eastern time, on [                    ], the day before the King special meeting, as applicable. If you hold Mylan shares or King shares in the name of a bank or broker, please follow the voting instructions provided by your bank or broker to ensure that your shares are represented at your shareholders’ special meeting. Please note that most banks and brokers permit their beneficial owners to vote by telephone or by Internet. If you hold shares in street name, see the next question and answer.
 
Q: If my shares are held in street name by my broker, how do I vote?
 
A: If you hold your shares in a stock brokerage account or if your shares are held by a bank or nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank or broker. Please note that you may not vote shares held in street name by returning a proxy card directly to Mylan or King or by voting in person at your shareholders’ special meeting unless you provide a “legal proxy,” which you must obtain from your bank or broker.
 
Q: What will happen if I abstain from voting or do not return a proxy card or otherwise vote?
 
A: If you are a Mylan shareholder and abstain from voting or do not return a proxy card or otherwise vote, such action will have no effect on the proposal to approve the issuance of shares of Mylan common stock pursuant to the merger, because only those votes cast “FOR” or “AGAINST” the proposal will be counted.

If you are a King shareholder and abstain from voting or do not return a proxy card or otherwise vote, such action will have the same effect as a vote “AGAINST” the proposal to approve and adopt the merger agreement and approve the merger.
 
Q: What will happen if I return my proxy card without indicating how to vote?
 
A: If you sign and return your proxy card without indicating how to vote on any particular proposal, the Mylan or King common stock represented by your proxy will be voted in favor of that proposal.
 
Q: Can I revoke my proxy or change my vote even after returning a proxy card?
 
A: Yes. You can revoke your proxy or change your vote before your proxy is voted at your shareholders’ special meeting. You can do this in one of four ways:

• you can send a signed notice of revocation;

• you can grant a new, valid proxy bearing a later date;

• you can cast a new vote over the Internet or by telephone; or

• if you are a holder of record, you can attend your shareholders’ special meeting and vote in person, which will automatically cancel any proxy previously given, or you may revoke your proxy in person, but your attendance alone will not revoke any proxy that you have previously given.

Table of Contents

 
If you choose to send a signed notice of revocation, you must submit your notice of revocation or your new proxy to the Secretary of Mylan or the Secretary of King, as applicable, and it must be received at the appropriate address on page 95 or page 99, respectively, no later than the beginning of your shareholders’ special meeting. If you choose to cast a new vote over the Internet or by telephone you must do so before 11:59 p.m., Eastern time, on [          ], the day before the Mylan special meeting or before 11:59 p.m., Eastern time, on [          ], the day before the King special meeting, as applicable. If your shares are held in street name by your broker, you should contact your broker to change your vote.
 
Q: What do I need to do now?
 
A: Carefully read and consider the information contained in and incorporated by reference in this joint proxy statement/ prospectus, including its annexes, and vote the proxy card you receive, vote over the Internet or by telephone. We encourage you to vote the proxy card you receive, as soon as possible, even if you plan to attend your shareholders’ special meeting, to ensure that your shares are represented at the applicable special meeting of shareholders and voted as directed.
 
Q: Should I send in my stock certificates now?
 
A: No. King shareholders should not send in any stock certificates now. After the merger is completed, Mylan’s exchange agent will send former King shareholders a letter of transmittal explaining what they must do to exchange their King stock certificates for stock certificates representing the shares of Mylan common stock payable to them pursuant to the merger.

If you are a Mylan shareholder, you are not required to take any action with respect to your Mylan stock certificates.
 
Q: When is the merger expected to be completed?
 
A: We are working to complete the merger as soon as possible. If the Mylan shareholders approve the issuance of shares of Mylan common stock pursuant to the merger, the King shareholders approve and adopt the merger agreement and approve the merger, and all closing conditions in the merger agreement are satisfied or waived, Mylan and King anticipate that the merger will be completed in the fourth quarter of the 2004 calendar year.
 
Q: What are the tax consequences of the merger to me?
 
A: It is expected that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which is referred to as the Code. Assuming the merger so qualifies, for U.S. federal income tax purposes, holders of King common stock will not recognize gain or loss in connection with the conversion of their shares of King common stock into the right to receive shares of Mylan common stock and the receipt of shares of Mylan common stock in the merger, except to the extent of cash, if any, received in lieu of a fractional share of Mylan common stock. Please refer to the section of this joint proxy statement/ prospectus entitled “Certain U.S. Federal Income Tax Consequences of the Merger” beginning on page 65.
 
Q: Who can answer my questions?

  •  the completion of all filings with governmental entities, and the receipt of all governmental and regulatory consents, approvals and authorizations, in each case that are necessary for the merger, unless failure to make or obtain them would not, individually or in the aggregate, have a material adverse effect on Mylan (after giving effect to the merger);

      Merrill Lynch, Pierce, Fenner & Smith Incorporated, Mylan’s exclusive financial advisor for the merger, has rendered a written opinion, dated July 23, 2004, to the Mylan board of directors as to the fairness, from a financial point of view, to Mylan of the 0.9 exchange ratio provided for in the merger. The full text of the written opinion of Merrill Lynch is attached to this joint proxy statement/ prospectus as Annex B. We encourage you to read the opinion carefully in its entirety to understand the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Merrill Lynch in providing its opinion. The opinion of Merrill Lynch is directed to the Mylan board of directors and does not constitute a recommendation to any shareholder with respect to any matter relating to the merger. Pursuant to the terms of an engagement letter with Merrill Lynch, Mylan has agreed to pay Merrill Lynch a transaction fee, a portion of which was payable upon execution of the merger agreement and a portion of which is payable upon consummation of the merger.

Consequences of Merger Not Being Approved (See page 28)

      If either the Mylan or the King shareholders fail to approve the proposals required to effect the merger at their respective meetings, or if the merger is otherwise not completed, the ongoing businesses of each of Mylan and King may be negatively affected. Additionally, both parties will have incurred costs associated with the merger without realizing the benefits of having the merger completed.

Risks Associated with the Merger (See page 24)

      While the merger is pending and if the merger is completed, shareholders of Mylan and King will be subject to a number of risks to which they otherwise may not be subject. These risks include, among others, the following:

  •  The exchange ratio is fixed and will not be adjusted in the event of any change in either Mylan’s or King’s stock price. Accordingly, because the market price of Mylan common stock may fluctuate, Mylan shareholders cannot be sure of the market value of the consideration Mylan will pay in the merger, and King shareholders cannot be sure of the market value of the consideration they will receive in the merger.
 
  •  The market price of Mylan’s common stock may be affected after the merger by factors different from those affecting the shares of Mylan and King currently, and may decline as a result of the merger.
 
  •  The integration of the businesses of Mylan and King following the merger will present challenges, and the combined company may not realize the anticipated benefits of the merger to the extent or in the time frame expected.

Interests of King Directors and Executive Officers in the Merger (See page 57)

      In considering the recommendation of the King board of directors to vote for the proposal to approve and adopt the merger agreement and approve the merger, shareholders of King should be aware that members of King’s board of directors and King’s executive officers have agreements or arrangements that provide them with interests in the merger and the merger agreement that are different from, or in addition to, the interests of King and King’s shareholders generally. The King board of directors was aware of these agreements and arrangements during its deliberations on the merits of the merger and the merger agreement and in unanimously (with one director absent) determining to recommend that the shareholders of King vote for the proposal to approve and adopt the merger agreement and approve the merger. These interests include:

  •  King stock options granted to employees (including executive officers) that are outstanding at the completion of the merger will accelerate and become fully exercisable if the employee’s employment terminates following the completion of the merger (other than in the case of a termination for cause);
 
  •  unvested stock options held by King’s non-employee directors at the completion of the merger will accelerate and become fully exercisable upon the directors’ resignation from King’s board of directors, which will occur upon the completion of the merger;
 
  •  King’s executive officers will receive enhanced severance benefits if their employment is terminated “without cause”, or if they resign for “good reason”, following the completion of the merger;
 
  •  Mylan has proposed certain terms of an employment agreement that Mylan may enter into with King’s chief financial officer;
 
  •  up to $6.8 million of retention bonuses are expected to be paid to King’s employees, which employees may include executive officers;
 
  •  King’s executive officers will each receive a bonus under King’s Executive Management Incentive Plan for 2004; and

  •  upon the completion of the merger, directors of King participating in King’s Non-Employee Director Deferred Compensation Plan will receive their account balances under the plan in a lump-sum cash payment.

Regulatory Approvals Required for the Merger (See page 62)

      U.S. Antitrust Laws. Under the HSR Act and its associated rules, the merger may not be completed until notifications have been given and certain information and materials have been furnished to and reviewed by the Antitrust Division of the U.S. Department of Justice and the Federal Trade Commission and the required waiting period has expired or been terminated. Mylan and King filed the required notification and report forms under the HSR Act with the Federal Trade Commission and the Department of Justice on September 2, 2004. The waiting period will expire on October 4, 2004 (30 days after the forms were filed or on the next regular business day if the 30th day falls on a Saturday, Sunday or legal public holiday) unless early termination of the applicable waiting period is granted or a request for additional information is issued. If a request for additional information is issued, the parties would not be able to complete the merger until 30 days after both parties substantially comply with that request, or on the next regular business day if the 30th day falls on a Saturday, Sunday or legal public holiday.

      Other Approvals. The merger is not subject to any merger control filings under foreign antitrust laws.

Accounting Treatment (See page 63)

      Mylan prepares its financial statements in accordance with applicable SEC rules and regulations and accounting principles generally accepted in the United States of America, which are referred to as U.S. GAAP. The merger will be accounted for using the purchase method of accounting with Mylan being considered the acquirer of King for accounting purposes. This means that Mylan will allocate the purchase price to the fair value of assets acquired (including identifiable intangible assets) and liabilities assumed from King on the closing date, with the excess purchase price being recorded as goodwill. Under the purchase method of accounting, goodwill is not amortized but is tested for impairment at least annually.

Certain U.S. Federal Income Tax Consequences of the Merger (See page 65)

      It is expected that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Assuming the merger qualifies as such a reorganization, for U.S. federal income tax purposes, holders of King common stock will not recognize gain or loss in connection with the conversion of their shares of King common stock into the right to receive shares of Mylan common stock and the receipt of shares of Mylan common stock in the merger, except to the extent of cash, if any, received in lieu of a fractional share of Mylan common stock. It is a condition to the completion of the merger that Mylan and King receive written opinions from their respective counsel to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither Mylan nor King intends to waive this closing condition. In the event that either Mylan or King waives receipt of such opinion from its counsel, however, Mylan and King will resolicit the approval of their respective shareholders after providing appropriate disclosure.

      Tax matters are very complicated and the tax consequences of the merger to each King shareholder will depend on such shareholder’s particular facts and circumstances. King shareholders are urged to consult their tax advisors to understand fully the tax consequences to them of the merger.

Expenses

      Generally, all fees and expenses incurred in connection with the merger agreement and the transactions contemplated by the merger agreement will be paid by the party incurring those expenses, subject to the specific exceptions discussed in this joint proxy statement/ prospectus.

Dissenters’ Rights (See page 64)

      Under Tennessee law, King shareholders are not entitled to dissenters’ rights in connection with the merger if King common stock is listed on the NYSE at the time the merger is completed.

Selected Historical Financial Information

      We are providing the following financial information to assist you in your analysis of the financial aspects of the acquisition. We derived the annual Mylan historical information from the consolidated financial statements of Mylan as of and for each of the years ended March 31, 2000 through 2004. We derived the annual King historical information from the consolidated financial statements of King as of and for each of the years ended December 31, 1999 through 2003. The current report on Form 8-K of King, dated September 3, 2004, restates King’s consolidated financial statements for each of the three years in the period ended December 31, 2003, solely to reflect the reclassification of the results of operations and financial position of King’s Prefest® and Nordette® product rights from continuing operations to discontinued operations as required by the rules of the SEC. The data as of and for the three months ended June 30, 2004, in the case of Mylan, and as of and for the six months ended June 30, 2004, in the case of King, has been derived from interim financial statements of both Mylan and King, which in the opinion of each company’s management, include all normal and recurring adjustments that are considered necessary for the fair presentation of the results for the interim period. The information is only a summary and should be read in conjunction with each company’s historical consolidated financial statements and related notes contained in Mylan’s annual report on Form 10-K for the year ended March 31, 2004, Mylan’s quarterly report on Form 10-Q for the quarter ended June 30, 2004, King’s current report on Form 8-K dated September 3, 2004, and King’s quarterly reports on Form 10-Q for the quarters ended March 31, 2004 and June 30, 2004, which have been incorporated by reference herein, as well as other information that has been filed with the SEC. See “Where You Can Find More Information” on page 118 for information on where you can obtain copies of this information. The historical results included below and elsewhere in this document may not be indicative of the future performance of Mylan, King or the combined company.

Selected Unaudited Condensed Combined Pro Forma Financial Information

      The statements contained in this section may be deemed to be forward-looking statements within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act. Forward-looking statements are typically identified by the words “believe”, “expect”, “anticipate”, “intend”, “estimate” and similar expressions. These forward-looking statements are based largely on management’s expectations and are subject to a number of uncertainties. Actual results could differ materially from these forward-looking statements. Neither Mylan nor King undertake any obligation to update publicly or revise any forward-looking statements. For a more complete discussion of the risks and uncertainties, which may affect such forward-looking statements, please refer to the section entitled “Cautionary Statement Regarding Forward-Looking Statements” on page 31.

      The following selected unaudited condensed combined pro forma financial data present the effect of the acquisition of King by Mylan. The following selected unaudited condensed combined pro forma statement of earnings data for the twelve months ended March 31, 2004, is extracted from the audited historical consolidated statement of earnings of Mylan for the fiscal year ended March 31, 2004, and the unaudited condensed statement of earnings of King for the twelve months ended March 31, 2004, and combined as if the acquisition had occurred on April 1, 2003. The unaudited condensed statement of earnings of King for the twelve months ended March 31, 2004, has been prepared by adding the unaudited three-month period then ended to the audited statement of earnings for the year ended December 31, 2003, and subtracting the results for the unaudited period ended March 31, 2003. The following selected unaudited condensed combined pro forma statement of earnings data for the three months ended June 30, 2004, is extracted from the historical unaudited condensed consolidated statements of earnings of Mylan and of King for the three months ended June 30, 2004, and combined as if the acquisition had occurred on April 1, 2003. The following selected unaudited condensed combined pro forma balance sheet data is extracted from the unaudited historical condensed consolidated balance sheets of Mylan and of King as of June 30, 2004, and combined giving effect to the acquisition as if it had occurred on June 30, 2004.

      The unaudited condensed combined pro forma financial data was prepared using the purchase method of accounting. The allocation of the purchase price as reflected in the pro forma condensed combined financial data has been based upon preliminary estimates of the fair values of assets acquired and liabilities assumed as of the date of the acquisition. Management is currently assessing the fair values of the tangible and intangible assets acquired and liabilities assumed. This preliminary allocation of the purchase price is dependent upon certain estimates and assumptions, which are preliminary and have been made solely for the purpose of developing such unaudited pro forma condensed combined financial data.

      A final determination of the fair value of King’s assets and liabilities, which cannot be made prior to the completion of the transaction, will be based on the actual net tangible and intangible assets of King that exist as of the date of completion of the acquisition and such valuations could change significantly upon the completion of further analyses and asset valuations from those used in the condensed combined pro forma financial data presented below.

      The unaudited condensed combined pro forma financial data does not include liabilities resulting from integration planning and adjustments in respect of possible settlements of outstanding litigation (other than those already included in the historical financial statements of either company) as these are not presently estimable. Amounts preliminarily allocated to goodwill may significantly decrease and amounts allocated to intangible assets with definite lives may increase significantly, which could result in a material increase in amortization of acquired intangible assets. Therefore, the actual amounts recorded as of the completion of the transaction may differ materially from the information presented in the accompanying unaudited condensed combined pro forma financial statements. In addition to the completion of the final valuation of acquired assets and liabilities, the impact of ongoing integration activities, the timing of completion of the transaction and other changes in King’s net tangible and intangible assets that occur prior to completion of the transaction could cause material differences in the information presented.

      The unaudited condensed combined pro forma financial data are not necessarily an indication of the results that would have been achieved had the transaction been completed as of the dates indicated or that may be achieved in the future.

(1)  Although the dividend policy of the combined company is subject to approval by Mylan’s board of directors, it is anticipated that Mylan will continue to pay dividends following the acquisition. Assuming Mylan’s current annual dividend of $0.12 per share and the pro forma weighted average common shares outstanding, this would equate to approximately $58.3 million annually or $14.6 million quarterly.

Comparative Per Share Information

      The following table sets forth selected historical per share information of Mylan and King and unaudited pro forma combined per share information after giving effect to the acquisition of King by Mylan, accounted for under the purchase method of accounting, assuming that 0.9 shares of Mylan common stock had been issued in exchange for each outstanding share of King common stock. You should read this information in conjunction with the selected historical financial information, included elsewhere in this document, and the historical financial statements of Mylan and King that are incorporated in this document by reference. The unaudited Mylan pro forma combined per share information is derived from, and should be read in conjunction with, the Unaudited Condensed Combined Pro Forma Financial Statements and related notes included on page [93] of this joint proxy statement/prospectus. The historical per share information is derived from unaudited financial statements of both Mylan and King as of and for the three months ended June 30, 2004, the audited financial statements as of and for the year ended March 31, 2004, with respect to Mylan, and the unaudited condensed statement of earnings for the twelve months ended March 31, 2004, with respect to King. The unaudited condensed statement of earnings of King for the twelve months ended March 31, 2004 has been prepared by adding the results for the unaudited three-month period then ended to the audited statement of earnings for the year ended December 31, 2003, and subtracting the results for the unaudited three-month period ended March 31, 2003. The unaudited pro forma King per share equivalents are calculated by multiplying the unaudited Mylan pro forma combined per share amounts by the exchange ratio of 0.9.

      The unaudited pro forma combined per share information does not purport to represent what the actual results of operations of Mylan and King would have been had the companies been combined or to project Mylan’s and King’s results of operations that may be achieved after the acquisition.

(1)  Mylan’s current quarterly dividend is $0.03 per share ($0.12 per share annualized) and is subject to future approval and declaration by Mylan’s board of directors. King has never paid cash dividends on its common stock and, under the merger agreement, King has agreed not to pay dividends pending the completion of the merger without the prior written consent of Mylan. Although the dividend policy of the combined company is subject to approval by Mylan’s board of directors, it is anticipated that Mylan will continue to pay dividends following the acquisition. Assuming Mylan’s current annual dividend of $0.12 per share and the pro forma weighted average common shares outstanding, this would equate to approximately $58.3 million annually or $14.6 million quarterly.
 
(2)  Amounts are calculated by multiplying unaudited Mylan pro forma combined per share amounts by the exchange ratio in the acquisition (0.9 shares of Mylan common stock for each share of King common stock).

Recent Closing Prices

      The following table sets forth the closing prices per share of Mylan common stock and King common stock as reported on the NYSE Composite Transaction Tape on July 23, 2004, the last full trading day prior to the announcement of the acquisition, and [                    ], 2004, the most recent practicable date prior to the mailing of this joint proxy statement/prospectus to Mylan’s and King’s shareholders. This table also sets forth the equivalent price per share of King common stock on those dates. The equivalent price per share is equal to the closing price of a share of Mylan common stock on that date multiplied by 0.9, the applicable exchange ratio in the acquisition. These prices will fluctuate prior to the special meetings and the acquisition, and shareholders are urged to obtain current market quotations prior to making any decision with respect to the acquisition.

Dividend Information

      Although dividends are subject to future approval and declaration by Mylan’s and King’s respective boards of directors, Mylan currently plans to continue to pay regular quarterly dividends on its common stock until closing of the acquisition. King has never paid a cash dividend on its common stock and, under the merger agreement, King has agreed not to pay dividends pending the completion of the merger without the prior written consent of Mylan. The dividend policy of the combined company is subject to approval by Mylan’s board of directors, however, it is anticipated that Mylan will continue to pay dividends following the acquisition. Assuming Mylan’s current annual dividend of $0.12 per share and the pro forma weighted average common shares outstanding, this would equate to approximately $58.3 million annually or $14.6 million quarterly.

RISK FACTORS RELATING TO THE MERGER

      The merger involves risks for Mylan and King shareholders. King shareholders will be choosing to invest in Mylan common stock by voting in favor of the merger and Mylan shareholders will be choosing to permit significant dilution of their percentage ownership in Mylan by voting in favor of the issuance of stock in the merger. In addition to the other information included and incorporated by reference in this joint proxy statement/prospectus, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” on page 31, you should carefully consider the following risks before deciding how to cast your vote. In addition, you should read and consider the risks associated with each of the businesses of Mylan and King, because these risks will also affect the combined company. These risks can be found in Mylan’s Annual Report on Form 10-K for the year ended March 31, 2004, Mylan’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2004, King’s Annual Report on Form 10-K for the year ended December 31, 2003 and King’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2004 and June 30, 2004, which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus. You should also read and consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference in this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page [131]. Additional risks and uncertainties not presently known to Mylan or King or that are not currently believed to be important also may adversely affect the merger and the combined company after the merger.

 
The exchange ratio is fixed and will not be adjusted in the event of any change in either Mylan’s or King’s stock price. Accordingly, because the market price of Mylan common stock may fluctuate, at the time of the Mylan special shareholders’ meeting, Mylan shareholders cannot be sure of the market value of the consideration that Mylan will pay in the merger, and at the time of the King special shareholders’ meeting, King shareholders cannot be sure of the market value of the consideration they will receive in the merger.

      Under the merger agreement, King shareholders will receive, upon completion of the merger, consideration equal to 0.9 shares of Mylan common stock for each share of King common stock they own. The 0.9 to 1 exchange ratio was agreed upon in the merger agreement, and will not be adjusted due to any increases or decreases in the price of Mylan common stock. In addition, neither party has a right to terminate the merger agreement based solely upon changes in the market price of Mylan’s or King’s common stock, and the merger agreement contains no other provisions that would limit the impact of increases or decreases in the market price of Mylan’s or King’s common stock. As a result, any changes in the value of Mylan’s common stock will have a corresponding effect on the value of the consideration that Mylan pays to King shareholders in the merger.

      The market price of Mylan common stock at the time of completion of the merger may vary significantly from the price on the date of the merger agreement or from the price on the dates of the Mylan and King shareholders’ meetings. These variations may be caused by a variety of factors, including:

  •  changes in the business, operations and prospects of Mylan or King;
 
  •  changes in market assessments of the business, operations and prospects of the combined company;
 
  •  market assessments of the likelihood that the merger will be completed;
 
  •  interest rates, general market and economic conditions and other factors generally affecting the price of Mylan’s and King’s common stock; and
 
  •  changes in federal, state and local legislation, governmental regulation and other legal developments affecting Mylan or King.

      Mylan common stock has historically experienced volatility. The closing price of Mylan common stock on the NYSE Composite Transactions Reporting System on July 23, 2004 was $18.51 per share. From July 23, 2004 through the date of this joint proxy statement/prospectus, the trading price of Mylan

23


Table of Contents

common stock ranged from a high of $[               ] per share to a low of $[               ] per share. Since the announcement of the merger, Mylan common stock has generally traded below the closing price on the last trading day preceding the announcement of the merger, and the market price of Mylan common stock may continue to fluctuate prior to the merger, which would result in corresponding fluctuations in the value of the consideration paid by Mylan to King shareholders in the merger. For example:

  •  if the price of Mylan common stock declines before the completion of the merger, King shareholders will receive shares of Mylan common stock that have a market value that may be less than the market value of such shares when the merger agreement was signed; or
 
  •  if the price of Mylan common stock increases before the completion of the merger, King shareholders will receive shares of Mylan common stock that have a market value that may be greater than the market value of such shares when the merger agreement was signed.

      In addition, because the date that the merger is completed may be later than the date of the Mylan special meeting, at the time of the Mylan special meeting Mylan shareholders may not be sure of the market value of the Mylan common stock that King shareholders will receive upon completion of the merger and Mylan may pay more for shares of King common stock than the value calculated on the date of the Mylan special meeting. Similarly, because the date that the merger is completed may be later than the date of the King special meeting, at the time of the King special meeting King shareholders may not be sure of the market value of the Mylan common stock they will receive upon completion of the merger or the market value of Mylan common stock at any time after the completion of the merger.

      We urge you to obtain current market quotations for Mylan and King common stock.

 
The market price of Mylan’s common stock may be affected after the merger by factors different from those affecting the shares of Mylan and King currently, and may decline as a result of the merger.

      Assuming that the merger is completed, the market price of Mylan’s common stock may decline as a result of the merger for a number of reasons, including that:

  •  the integration of King into Mylan may be unsuccessful, and could be more time-consuming and expensive than anticipated;
 
  •  the combined company may not achieve the anticipated benefits of the merger as rapidly as planned, or may not achieve those benefits at all; and
 
  •  the effect of the merger on Mylan’s financial results, including charges to earnings resulting from the application of the purchase method of accounting to the merger, may be worse than anticipated.

      The businesses of Mylan and King differ and, accordingly, the results of operations of the combined company and the market price of the combined company’s common stock may be affected by factors different from those currently affecting the independent results of operations of each of Mylan and King. In particular, the combination of Mylan and King to form a specialty pharmaceutical company with significant operations in both the generic and branded segments of the pharmaceutical industry creates a business that may be valued at lower levels by the marketplace than Mylan was valued prior to the merger.

 
The integration of the businesses of Mylan and King following the merger will present various challenges, and the combined company may not realize the anticipated benefits of the merger to the extent or in the time frame expected.

      The success of the merger will depend, in part, on the ability of Mylan and King to integrate their businesses efficiently and effectively. The combined company will be required to devote significant management attention and resources to integrating the diverse business practices and operations of Mylan and King. In addition, Mylan has not previously completed an acquisition comparable in size and scope to

24


Table of Contents

the merger. Potential difficulties the combined company may encounter in the integration process may include:

  •  maintaining employee morale, retaining key employees and integrating personnel from two separate corporate cultures;
 
  •  lost sales, customers or suppliers as a result of certain customers or suppliers of either of the two companies deciding not to do business with the combined company;
 
  •  the inability of the combined company to achieve the cost savings and operating synergies anticipated in the merger;
 
  •  complexities associated with managing the combined businesses, including those in connection with consolidating multiple physical locations;
 
  •  the diversion of management attention to issues related to integration, rather than ongoing business concerns and performance;
 
  •  coordinating promotional efforts and training the sales and marketing teams of King and Mylan to effectively promote the entire range of products of the combined businesses;
 
  •  unanticipated incompatibility of sales, purchasing and information systems as well as Medicaid and other governmental reporting systems and procedures; and
 
  •  potential unknown liabilities and increased costs associated with integration.

      The difficulties identified above or any others could cause the integration to be more time-consuming and expensive than anticipated, could result in an interruption of, or loss of momentum in, the activities of the combined company’s business or the loss of key personnel, many of whom have proprietary information, and could have an adverse effect on the business and financial results of the combined company.

      In addition, certain benefits and synergies of the merger depend upon, among other things, operational and other efficiencies, economies of scale and revenue enhancement opportunities, and cost savings associated with anticipated restructurings, including the avoidance of certain future costs that Mylan and King would otherwise have to incur, specifically Mylan’s costs in building a sales force for nebivolol. In order to realize these benefits and synergies, we must successfully combine the businesses of Mylan and King in a manner that permits those benefits and synergies, which are based on projections and assumptions, to be realized. Due to antitrust laws and regulations, Mylan and King have been able to conduct only limited planning regarding the integration of the two companies following the announcement of the merger and have not yet determined the exact nature in which the two companies will be combined after the merger. The actual integration may result in additional and unforeseen expenses or delays, and the anticipated benefits of such integration plans may not be realized.

 
In order to be successful, the combined company must retain and motivate key employees and failure to do so could seriously harm the combined company.

      In order to be successful, the combined company must retain and motivate executives and other key employees. Employees of Mylan or King may experience uncertainty about their future roles with the combined company until or after strategies for the combined company are announced or executed. These circumstances may adversely affect the combined company’s ability to retain key personnel. The combined company also must continue to motivate employees and keep them focused on the strategies and goals of the combined company, which may be particularly difficult due to the potential distractions of the merger.

 
Charges to earnings resulting from the application of the purchase method of accounting may adversely affect the market value of Mylan’s common stock following the merger.

      In accordance with U.S. GAAP, the combined company will account for the merger using the purchase method of accounting, which will result in charges to Mylan’s earnings that could adversely affect

25


Table of Contents

the market value of the common stock of Mylan following completion of the merger. Under the purchase method of accounting, the combined company will allocate the total purchase price to King’s net tangible assets, amortizable intangible assets, intangible assets with indefinite lives and in-process research and development based on their fair values as of the date of completion of the merger, and record the excess of the purchase price over those fair values as goodwill. The portion of the purchase price allocated to in-process research and development will be expensed by the combined company in the quarter in which the merger is completed. The combined company will incur additional depreciation and amortization expense over the useful lives of certain of the net tangible and intangible assets acquired in connection with the merger. In addition, to the extent the value of goodwill or intangible assets becomes impaired, the combined company may be required to incur material charges relating to the impairment of those assets. These depreciation, amortization, in-process research and development and potential impairment charges could have a material impact on the combined company’s results of operations and adversely affect the market value of Mylan’s common stock. See the section entitled “Unaudited Condensed Combined Pro Forma Financial Statements” beginning on page 82.
 
Obtaining approvals may delay or prevent completion of the merger, reduce the benefits of the merger to shareholders or result in additional transaction costs. Any significant delay in completing the merger could adversely affect the combined company.

      Completion of the merger is conditioned upon, among other things, the expiration or earlier termination of the waiting period under the HSR Act and may be subject to the receipt of consents and approvals of other government authorities. As a result, Mylan and King shareholders face the following risks:

  •  the requirement for obtaining these consents and approvals could delay the completion of the merger for a significant period of time after Mylan and King shareholders have approved the merger at their respective shareholders’ special meetings;
 
  •  the merger may not be completed if the required consents approvals are not obtained; and
 
  •  Mylan and King could agree to certain conditions or restrictions imposed by government authorities in order to obtain regulatory approval.

      Mylan and King cannot assure their shareholders that the merger will be completed, that there will not be a delay in the completion of the merger, that the merger will be completed on the terms contemplated by the merger agreement and as described in this joint proxy statement/prospectus or that the benefits of the merger will be the same as those described in this joint proxy statement/prospectus. Any delay could also, among other things, result in additional transaction costs, loss of revenue or other negative effects associated with uncertainty about completion of the merger. Mylan and King have not yet obtained any of the governmental or regulatory approvals required to complete the merger.

 
The merger agreement requires payment of a termination fee of $85 million in certain instances, which could deter a third party from proposing an alternative transaction to the merger.

      Under the terms of the merger agreement, Mylan and King may be required to pay to the other a termination fee of $85 million if the merger agreement is terminated under certain circumstances. This termination fee may discourage competing bidders from presenting proposals to acquire or merge with Mylan or King that, from a financial perspective, might be superior to the terms of the merger. For a description of the termination rights of each party and the termination fee payable under the merger agreement, see “The Merger Agreement — Termination Fee” beginning on page 79.

 
Some of King’s directors have potential conflicts of interest in recommending that King shareholders vote for the proposal to approve and adopt the merger agreement and approve the merger.

      Some directors of King (including two who are executive officers of King) who are recommending that you vote in favor of approving and adopting the merger agreement and approving the merger

26


Table of Contents

participate to different extents in King stock option, severance, employment and/or other benefit arrangements that provide them with interests in the merger and merger agreement that are different from, or in addition to, the interests of King and King’s shareholders generally. These benefits received by King directors may include the acceleration of exercisability of stock options, the continuation of indemnification arrangements in connection with the merger and/or the payment of severance, bonus amounts and other benefits. The receipt of compensation and other benefits may have influenced these directors in making their recommendation to King shareholders. See “The Merger — Interests of King Directors and Executive Officers in the Merger” beginning on page 57.
 
Failure to complete the merger could negatively impact the stock prices and the future business and financial results of Mylan and King.

      If the merger is not completed, the ongoing businesses of Mylan or King may be adversely affected and Mylan and King will be subject to several risks, including the following:

  •  either party being required, under certain limited circumstances, to pay the other party a termination fee of $85 million under the merger agreement;
 
  •  both parties having incurred significant costs relating to the merger, such as legal, accounting, consulting, printing and financial advisor fees; and
 
  •  a significant portion of the attention of management of each of the companies having been on the merger instead of on pursuing other opportunities that could be beneficial to the companies,

in each case, without realizing any of the benefits of completing the merger.

      In addition, the completion of the merger is subject to approvals by the shareholders of Mylan and King, which might not be obtained. The issuance of shares of Mylan common stock pursuant to the merger agreement requires the affirmative vote of a majority of the votes cast at the Mylan special meeting. Approval and adoption of the merger agreement and approval of the merger requires the affirmative vote of a majority of the outstanding common shares of King. If either shareholder approval is not obtained, or if either special meeting is adjourned or postponed without the shareholder approval being obtained, the conditions of closing of the merger will not be satisfied and the closing of the merger will not occur.

      If the merger is not completed, the price of Mylan common stock and King common stock may decline to the extent that the current market price of Mylan common stock and King common stock reflects a market assumption that the merger will be completed. In addition, Mylan’s business and King’s business may be harmed to the extent that customers, suppliers and others believe that the companies cannot effectively compete in the marketplace without the merger, or otherwise remain uncertain about the companies. If the merger is not completed, Mylan and King cannot assure their shareholders that these risks will not materialize and will not materially affect the business, financial results and stock prices of Mylan or King.

 
The pro forma financial statements are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger.

      The pro forma financial statements contained in this joint proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger for several reasons. The pro forma financial statements have been derived from the historical financial statements of Mylan and King and certain adjustments and assumptions have been made regarding the combined company after giving effect to the merger. The information upon which these adjustments and assumptions have been made is preliminary, and these kinds of adjustments and assumptions are difficult to make with complete accuracy. Moreover, the pro forma financial statements do not reflect all costs that are expected to be incurred by the combined company in connection with the merger. For example, the impact of any incremental costs incurred in integrating the two companies is not reflected in the pro forma financial statements. As a result, the actual

27


Table of Contents

financial condition and results of operations of the combined company following the merger may not be consistent with, or evident from, these pro forma financial statements.

      The assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the combined company’s financial condition or results of operations following the merger. Any potential decline in the financial condition or results of operations may cause significant variations in the stock price of the combined company. See the section entitled “Unaudited Condensed Combined Pro Forma Financial Statements” beginning on page 82.

 
Mylan and King are the subject of various legal proceedings.

      Mylan and King are involved in various patent and product liability claims and litigation and additional matters that arise from time to time in the ordinary course of business. These include challenges to the coverage and/or validity of patents on products or processes and allegations of injuries caused by drugs or medical devices. In addition, Mylan and King are subject to national, state and local environmental laws and regulations. Mylan and King are also involved in or are the subject of governmental or regulatory agency inquiries or investigations from time to time. In particular, governmental investigations, such as the current investigation of King by the SEC and Office of Inspector General of the Department of Health and Human Services and other governmental agencies, other possible governmental investigations, litigation under securities laws and litigation under the Employee Retirement Income Security Act, which is referred to as ERISA, could have a material adverse effect on our business. For more information about Mylan’s and King’s legal proceedings, see our filings with the SEC that are incorporated by reference into this document under the headings “Contingencies” and “Legal Proceedings.”

 
If the combined company is unable to manage growth profitably, its business and financial results could suffer.

      The combined company’s future financial results will depend in part on its ability to profitably manage its core businesses, including any growth that the combined company may be able to achieve. Over the past several years, each of Mylan and King has engaged in the identification of, and competition for, growth and expansion opportunities. In order to achieve those initiatives, the combined company will need to maintain existing customers and attract new customers, recruit, train, retain and effectively manage employees, as well as expand operations, customer support and financial control systems. If the combined company is unable to manage its businesses profitably, including any growth that the combined company may be able to achieve, its business and financial results could suffer.

 
Some provisions contained in Mylan’s articles of incorporation, bylaws and shareholder rights plan, as well as provisions of Pennsylvania law, could impair a takeover attempt.

      Mylan has provisions in its articles of incorporation and bylaws that could have the effect of rendering more difficult or discouraging an acquisition deemed undesirable by the Mylan board of directors. These include provisions:

  •  authorizing blank check preferred stock, which could be issued with voting, liquidation, dividend and other rights superior to its common stock;
 
  •  limiting the liability of, and providing indemnification to, directors and officers;
 
  •  limiting the ability of Mylan shareholders to call a special meeting, requiring advance notice of shareholder proposals for business to be conducted at an annual meeting of Mylan shareholders and for nominations of candidates for election to the Mylan board of directors;
 
  •  controlling the procedures for conduct of board and shareholder meetings and election and removal of directors;

28


Table of Contents

  •  specifying that, as a practical matter, shareholders may take action only at a duly called annual or special meeting of shareholders; and
 
  •  requiring the affirmative vote of 75% of the outstanding shares of Mylan common stock entitled to vote to take certain actions in connection with transactions with any person who beneficially owns 10% or more of the outstanding shares of Mylan common stock.

These provisions, alone or together, could deter or delay hostile takeovers, proxy contests and changes in control or management of Mylan.

      In addition, Mylan has adopted a shareholder rights plan. The rights are not intended to prevent a takeover of Mylan. However, the rights may have the effect of rendering more difficult or discouraging an acquisition of Mylan deemed undesirable by the Mylan board of directors. The rights would cause substantial dilution to a person or group that attempted to acquire Mylan on terms or in a manner not approved by the Mylan board of directors, except pursuant to an offer conditioned upon redemption of the rights.

      As a Pennsylvania corporation, Mylan is also subject to applicable provisions of Pennsylvania law that could impair a takeover attempt. Any provision of Mylan’s articles of incorporation or bylaws, Mylan’s shareholder rights plan or Pennsylvania law that has the effect of delaying or deterring a change in control could limit the opportunity for Mylan shareholders (including former King shareholders who become Mylan shareholders upon completion of the merger) to receive a premium for their shares of Mylan common stock, and could also affect the price that some investors are willing to pay for Mylan common stock.

THE MERGER

      The following is a discussion of the proposed merger and the merger agreement. This is a summary only and may not contain all of the information that is important to you. A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated by reference herein. Mylan and King shareholders are urged to read this entire joint proxy statement/prospectus, including the merger agreement, for a more complete understanding of the merger.

Background of the Merger

      As participants in the pharmaceutical industry, the managements of Mylan and King are generally familiar with each other’s business. On an ongoing basis, each of Mylan and King evaluates alternatives for achieving its long-term strategic goals and enhancing long-term shareholder value.

      Mylan’s founder and Chairman, Milan Puskar, has long held a vision of creating a well-balanced specialty pharmaceutical company, meaning both a strong generic franchise along with a strong branded franchise. The Mylan board of directors and management have periodically assessed strategic options for Mylan as part of its ongoing efforts to realize that vision and create a well-balanced pharmaceutical company. Currently, Mylan has a leading generic franchise and a developing brand business and has recently submitted to the FDA an NDA for nebivolol, a beta blocker, which was accepted for filing by the FDA in June 2004. Mylan believes nebivolol will be the cornerstone to build its brand franchise.

      In this regard, in early 2004, Mylan took a significant step towards establishing its brand franchise by filing the NDA with the FDA for nebivolol. In considering the establishment of its brand franchise, Mylan management and its board evaluated several alternatives as to how to establish such a brand franchise, which included out-licensing, partnering, building on its own or acquiring a platform. Further, it considered that an important benefit of a brand franchise would be the ability to deliver sustained growth and yield increased shareholder value over the long term. As part of the establishment of a brand franchise, Mylan’s management and its board determined that it would be better positioned to fully develop a brand franchise not only around nebivolol but around an existing experienced business with expertise in cardiovascular products. In addition, both Mylan’s management and board of directors recognized that in order to leverage the brand franchise and the related sales force to launch and sell nebivolol additional products would be required. Therefore, to achieve that strategy, Mylan management initiated a general analysis of various possible business combinations using publicly available information and on that basis determined that King’s branded pharmaceutical products and its experienced cardiovascular sales force could strengthen the platform from which Mylan plans to launch nebivolol and could be complementary to Mylan’s existing product portfolio.

      Since its inception, King has sought out and executed strategic opportunities for growth. In late January 2004, Mr. Jefferson Gregory, then the Chairman of the Board and Chief Executive Officer of King, received a telephone call from the chief executive officer of another specialty pharmaceutical company, who indicated that his company was interested in a strategic business combination with King. At that time, King faced various strategic challenges, primarily increased competition from generic pharmaceutical companies, particularly with respect to several of King’s key products. Over the next several weeks, senior management of each of King and the specialty pharmaceutical company exchanged presentations and information pursuant to a confidentiality agreement between the two companies, and held high level discussions regarding the nature of a possible business combination transaction.

      On February 19, 2004, Mr. Gregory announced his plan to retire as Chief Executive Officer of King and to remain in the position until the board appointed a successor. Upon the announcement, Mr. Coury contacted Goldman Sachs to establish a meeting with Mr. Gregory to discuss a potential Mylan and King business combination.

      In early March 2004, Mr. Coury and Mr. Gregory met to explore a potential business combination of Mylan and King. Following this initial meeting, certain members of management of both companies met to discuss further the possibility of a business combination. On March 17, 2004, Messrs. Coury and

Gregory again met to discuss the possibility of a business combination, and on that date Mylan and King executed a confidentiality agreement to allow the exchange of confidential information between them. Shortly thereafter, Mylan commenced a due diligence review of King. In addition, during March 2004, discussions between King and the specialty pharmaceutical company continued, but the specialty pharmaceutical company failed to make an attractive offer for a business combination with King and, in late March, King ceased discussions with the specialty pharmaceutical company.

      From late March 2004 through early May 2004, Mylan, together with its financial advisor, Merrill Lynch, its legal advisor, Skadden, Arps, Slate, Meagher & Flom LLP, sometimes referred to as Skadden, Arps, its accounting and certain of its other advisors, conducted a due diligence investigation of King. Mylan also conducted site visits to certain of King’s facilities. In addition, during late April 2004 and continuing through early May 2004, King and its legal, financial, accounting and other advisors conducted a due diligence investigation of Mylan.

      During April and early May 2004, Mylan’s board of directors met multiple times to discuss developments in the due diligence investigation of King and the discussions in connection with a potential transaction between Mylan and King. Mylan’s board of directors also discussed the potential risks associated with an acquisition of King. Representatives of Merrill Lynch, Skadden, Arps, and other consultants and advisors also participated in these board meetings.

      Also during April and early May 2004, King’s board of directors held several meetings to discuss the strategic benefits and the risks associated with a business combination with Mylan. Representatives of King’s financial advisor, Goldman Sachs, and King’s legal advisor, Cravath, Swaine & Moore LLP, sometimes referred to as Cravath, attended these meetings, and the King board of directors discussed with Goldman Sachs financial aspects of a potential transaction.

      On April 27, 2004, Skadden, Arps, provided King and its advisors with a draft merger agreement. During the period between April 28, 2004 and May 4, 2004, the parties engaged in a negotiation on the terms of the merger agreement and continued their respective due diligence investigations. On May 5, 2004, the parties determined not to continue discussions regarding a potential transaction due primarily to an inability to agree on certain terms of the merger agreement.

      On May 7, 2004, Mr. Coury sent a letter to King indicating Mylan’s continued interest in a possible acquisition of King.

      On May 17, 2004, King announced that Mr. Gregory had resigned from his positions as Chairman and as a member of the King Board and Chief Executive Officer effective May 14, 2004 and that, effective May 17, 2004, the King board of directors had appointed Brian A. Markison as acting President and Chief Executive Officer and had elected Ted G. Wood as non-executive Chairman of the King Board.

      In late June 2004, Mylan’s board of directors met twice to address the possibility of renewing discussions regarding the acquisition of King and authorized management to approach King to resume discussions.

      On June 30, 2004, Mr. Coury sent a letter to Mr. Wood indicating Mylan’s desire to recommence discussions about a possible acquisition of King and outlining certain terms for a proposed transaction. A revised version of the draft merger agreement on June 30, 2004 accompanied the letter from Mr. Coury.

      On July 9, 2004, the King board of directors met to discuss the transaction proposed in Mylan’s letter. Representatives of Cravath discussed the board’s fiduciary duties in considering a strategic business combination and discussed the terms proposed in Mylan’s letter. Representatives of Goldman Sachs reviewed various financial aspects related to the proposed transaction.

      On July 16, 2004, Messrs. Wood and Markison sent a letter to Mr. Coury in response to the proposal contained in Mylan’s letter dated June 30, 2004. Messrs. Wood and Markison’s letter contained, among other things, a proposal of alternative terms for the potential acquisition of King by Mylan, as well as a revised draft of the merger agreement.

Table of Contents

      The King board concluded that the best method to enhance shareholder value, either in the case of a potential acquisition of King by Mylan or in the case of King pursuing a stand-alone strategy, would be to appoint a permanent chief executive officer. Accordingly, on July 16, 2004, the King board of directors appointed Mr. Markison as King’s President and Chief Executive Officer and announced the election of Mr. Markison to the King board of directors.

      During the period between July 17 and July 23, 2004, King and Mylan, together with their respective advisors, engaged in negotiations regarding the terms of the merger agreement and updated their due diligence investigations that had been conducted in April and early May. On July 20, 2004, Mylan’s board of directors met to discuss developments with King that occurred since the last board meeting and negotiations in connection with the merger agreement. On July 23, 2004, King and Mylan finalized the terms of the proposed merger agreement.

      On July 23, 2004, the board of directors of Mylan met to discuss the terms of the merger agreement regarding the proposed acquisition of King by Mylan and to consider the approval of the proposed merger agreement. At Mylan’s board of directors meeting, management reported on the financial, legal and organizational due diligence and reviewed the strategic reasons for the proposed transaction and Mylan’s historical and projected financial results. Representatives of Skadden, Arps discussed with the board their fiduciary duties in considering a business combination and the legal terms of the merger and provided an update on the legal due diligence analysis of King. Representatives of Merrill Lynch reviewed with the board its financial analysis of the exchange ratio and rendered to the board an oral opinion, which was confirmed by delivery of a written opinion dated July 23, 2004, to the effect that, as of such date and based on and subject to the matters described in the opinion, the exchange ratio was fair, from a financial point of view, to Mylan. Following additional discussions, the board of directors of Mylan unanimously determined that the merger transaction with King was advisable and in the best interests of Mylan’s shareholders and approved the merger and related matters and authorized management to finalize and enter into definitive documents regarding the proposed combination.

      Also on July 23, 2004, the King board of directors met to consider the proposed transaction. At the meeting, Mr. Wood and Mr. Markison reviewed the transaction with the board, including the strategic reasons for the proposed transaction, the principal terms of the proposed transaction, a financial review of the proposed transaction, a review of King’s historical and projected financial results and the results of King’s due diligence review of Mylan. Representatives of Cravath discussed the board’s fiduciary duties in considering a strategic business combination and further discussed the terms of the merger agreement. The King board also considered the prospects for generic pharmaceutical companies in general and Mylan in particular, and representatives of Goldman Sachs presented its financial analyses related to the proposed transaction. In addition, Goldman Sachs delivered to the board its oral opinion, subsequently confirmed in writing, that, as of July 23, 2004, and subject to the assumptions, considerations, and limitations set forth in its opinion, the exchange ratio pursuant to the merger agreement was fair to King shareholders, from a financial point of view. Upon completing its deliberations, the board of directors of King unanimously (with one director absent) approved and adopted the merger agreement and approved the merger, declared them advisable to and in the best interests of King and its shareholders and resolved to recommend that King shareholders approve and adopt the merger agreement and approve the merger.

      After the close of the financial markets on July 23, 2004, Mylan and King finalized and executed the definitive merger agreement.

      On July 26, 2004, Mylan and King issued a joint press release announcing the proposed acquisition of King by Mylan.

Mylan’s Reasons for the Merger

      The Mylan board of directors believes that the terms of the merger are advisable and fair to and in the best interests of Mylan and its shareholders and has unanimously approved the merger agreement and the merger and recommends that the Mylan shareholders vote “FOR” the proposal to approve the issuance of Mylan common stock to King’s shareholders in the merger.

Table of Contents

      In reaching its conclusion, the Mylan board of directors consulted with Mylan’s management, as well as with Mylan’s legal, financial and other advisors, and considered a variety of factors weighing favorably towards the merger, including the material factors listed below.

      Expected Benefits of the Merger. The combination of Mylan and King is expected to result in several significant strategic benefits to Mylan, including the following:

  •  Product Portfolio. Mylan’s product portfolio is expected to grow substantially in the area of branded pharmaceutical products as a result of the combination and would include four products with sales exceeding $100 million for the twelve months ended March 31, 2004, Altace®, Thrombin®, Sonata® and Skelaxin®, resulting in a diverse and well-balanced portfolio of branded and generic pharmaceutical products as well as certain products in their pipeline.
 
  •  Strategic Position. The combination is expected to unite Mylan’s core strengths in supply chain management, manufacturing, science, compliance and intellectual property management with King’s well-developed sales and marketing infrastructure and expertise in identifying branded product opportunities; generate increased cash flow and financial flexibility to pursue additional growth and acquisition opportunities; and strengthen the combined company’s position in the highly competitive diversified specialty pharmaceutical industry.
 
  •  Growth Platform. King’s 1,200-person sales force and marketing infrastructure are expected to provide Mylan with a strong platform from which it can launch branded products, and, upon approval by the FDA, its anticipated launch of nebivolol in 2006, and advance Mylan’s long-term growth strategy.
 
  •  Potential to Obtain Additional Commercial Opportunities. The combined company may obtain additional opportunities due to its increased size, product development portfolio, capabilities and bargaining power.

      Mylan also anticipates that the transaction will result in several key financial benefits, including:

  •  Potential for Earnings and Revenue Growth. The merger will combine two large firms in the pharmaceutical industry, which is anticipated to create the opportunity for continued growth potential, improved financial returns and accelerated earnings growth. The combined company would be a larger enterprise with a broader and more diversified product portfolio than either Mylan or King on a stand-alone basis.
 
  •  Synergy Opportunities. Mylan believes that the potential synergies are expected to reach approximately $100 million on an annualized basis. These synergies are expected to come from, among other things, the avoidance of costs for building a sales force for Mylan’s nebivolol product as well as facility consolidations, sourcing opportunities, and administrative efficiencies.
 
  •  Stabilization of Revenues and Earnings. Mylan believes that following the merger, the combination of revenues and earnings from the combined company’s generic and branded businesses will provide a more stable base than those of either Mylan or King alone.
 
  •  Strong Operating Cash Flow. Mylan anticipates that cash flow from operations will increase as a result of the merger and result in greater financial flexibility, which is expected to enhance Mylan’s ability to pursue strategic growth opportunities.
 
  •  Greater Leverage. The combined company is expected to have greater leverage in obtaining financing for its operations.

      Other Material Factors Considered. During the course of its deliberations relating to the merger agreement and the merger, the Mylan board of directors considered the following factors in addition to the benefits described above:

  •  Mylan’s Operating and Financial Market Condition. The business operations and prospects of each of Mylan, King and the combined company, and the then-current financial market conditions

35


Table of Contents

  and historical market prices, volatility and trading information with respect to common shares of Mylan and King.
 
  •  Consideration of Uncertainty in Revenue Forecasts/ Changing Generic Environment. The risk that the forecasts relating to Mylan’s stand-alone business, as well as the combined businesses of Mylan and King on a pro forma basis, that were prepared by management and shared with the Mylan board and Mylan’s financial advisors, may not be achieved, particularly given the changing generic environment;
 
  •  Mylan Shareholders’ Ownership of the Combined Company. The fact that Mylan’s shareholders would hold approximately [56]% of the outstanding shares of the combined company as of the applicable record dates.
 
  •  Control of Combined Company. The fact that Mylan’s board of directors and management would control the combined company.
 
  •  Impact of the Transaction on Mylan Shareholders. The expectation that the combination of Mylan and King would inure to the benefit of Mylan’s shareholders through enhanced operational performance, reduced risk of volatility and greater stability of earnings.
 
  •  Impact of the Announcement of the Transaction on Business Operations. The impact of the announcement of the transaction on Mylan’s business operations and on its suppliers, creditors, customers and employees.
 
  •  Shareholder Vote. The fact that Mylan shareholders will have an opportunity to vote upon the proposal to issue shares of Mylan common stock in connection with the merger.
 
  •  Provisions of the Merger Agreement. The structure of the transaction and terms and conditions of the merger agreement, including the definition of “Material Adverse Effect.” See the section entitled “The Merger Agreement” beginning on page 67.
 
  •  Market Capitalization and Capital Structure. The relative market capitalization of Mylan and King and the expected capital structure of the combined company after the merger.
 
  •  Strategic Alternatives. The strategic alternatives available to Mylan.
 
  •  Financial Advisor’s Opinion. The opinion of Merrill Lynch dated July 23, 2004 as to the fairness, from a financial point of view, of the exchange ratio to Mylan. See the section entitled “— Opinion of Financial Advisor to Mylan” beginning on page 38.
 
  •  Due Diligence. The results of due diligence investigations of King by Mylan’s management and legal and certain other advisors.
 
  •  Market Reaction. Possible stock market reaction to the transaction.

      The Mylan board of directors weighed these factors against a number of other material factors identified in its deliberations weighing negatively against the merger, including:

  •  the challenges inherent in the combination of two geographically diverse businesses of the size and scope of Mylan and King and the possible diversion of management attention for an extended period of time;
 
  •  the risk of loss of key talent;
 
  •  the possibility that business partners may decide to terminate their relationship with the combined company;
 
  •  the dilutive effect of the merger on the share ownership of Mylan’s shareholders;
 
  •  the risk of not capturing all the anticipated synergies between Mylan and King and the risk that other anticipated benefits might not be fully realized;

36


Table of Contents

  •  additional potential problems and costs, including transaction costs, associated with the integration of Mylan and King into a single combined company;
 
  •  the risk of contingent liabilities associated with the business of King;
 
  •  the conditions to the merger agreement requiring receipt of certain regulatory approvals and clearances. See the section entitled “— Regulatory Approvals Required for the Merger” beginning on page 62;
 
  •  the terms of the merger agreement regarding King’s right to consider and negotiate acquisition proposals in certain circumstances, as well as the possible effects of the provisions regarding termination fees;
 
  •  the risk that the merger may not be consummated despite the parties’ efforts or that consummation may be unduly delayed, even if the requisite approvals are obtained from Mylan’s and King’s shareholders; and
 
  •  the other risks described in the section entitled “Risk Factors” beginning on page 24.

      After consideration of these material factors, the Mylan board of directors determined that these risks could be mitigated or managed by Mylan or King or the combined company, were reasonably acceptable under the circumstances or were unlikely to have a material impact on the merger or the combined company, and that, overall, these risks were significantly outweighed by the potential benefits of the merger.

      This discussion of the information and factors considered by the Mylan board of directors includes all of the material positive and negative factors considered by the Mylan board of directors, but it is not intended to be exhaustive and may not include all the factors considered by the Mylan board of directors. The Mylan board of directors did not quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination that the merger agreement and the merger are advisable and fair to and in the best interests of Mylan and its shareholders. Rather, the Mylan board of directors viewed its position and recommendation as being based on the totality of the information presented to and factors considered by it. In addition, individual members of the Mylan board of directors may have given differing weights to different factors. It should be noted that this explanation of the reasoning of the Mylan board of directors and certain information presented in this section is forward-looking in nature and, therefore, that information should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” in this joint proxy statement/prospectus, beginning on page 31.

Recommendation of the Mylan Board of Directors

      After careful consideration, the Mylan board of directors, on July 23, 2004, unanimously determined that the merger is fair and in the best interests of Mylan and its shareholders and unanimously approved the merger agreement, the merger and the issuance of common stock pursuant to the merger. For the factors considered by the Mylan board of directors in reaching its decision to approve the merger agreement and the merger, see the section entitled “— Mylan’s Reasons for the Merger” beginning on page 35. The Mylan board of directors recommends that the Mylan shareholders vote “FOR” the proposal to approve the issuance of Mylan common stock to King’s shareholders pursuant to the merger.

Opinion of Financial Advisor to Mylan

      Mylan retained Merrill Lynch to act as its exclusive financial advisor in connection with the proposed merger. On July 23, 2004, Merrill Lynch delivered to the Mylan board of directors an oral opinion, which was confirmed by delivery of a written opinion dated the same date, to the effect that, as of that date, and based upon and subject to the factors and assumptions set forth in the opinion, the exchange ratio of 0.9 provided for in the merger was fair, from a financial point of view, to Mylan. Merrill Lynch does not have any obligation to update, revise or reaffirm its opinion.

Table of Contents

      The full text of Merrill Lynch’s opinion, dated July 23, 2004, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Merrill Lynch, is attached as Annex B to this joint proxy statement/prospectus and is incorporated into this joint proxy statement/prospectus by reference. The summary of Merrill Lynch’s opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Mylan shareholders are urged to read the opinion carefully in its entirety. Merrill Lynch’s opinion was delivered to the Mylan board of directors for its information and is directed only to the fairness, from a financial point of view, of the exchange ratio to Mylan, does not address any other aspect of the merger, including the merits of the underlying decision by Mylan to engage in the merger, and does not constitute a recommendation to any Mylan shareholder as to how the shareholder should vote as to any matter relating to the merger.

      In preparing its opinion to the Mylan board of directors, Merrill Lynch performed various financial and comparative analyses, including those described below. The summary set forth below does not purport to be a complete description of the analyses underlying Merrill Lynch’s opinion or the presentation made by Merrill Lynch to the Mylan board of directors. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Merrill Lynch did not attribute any particular weight to any analysis or factor considered by it, but rather made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. Accordingly, Merrill Lynch believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors, or focusing on information presented in tabular format, without considering all of the analyses and factors or the narrative description of the analyses, would create a misleading or incomplete view of the process underlying its opinion.

      In performing its analyses, Merrill Lynch made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Merrill Lynch, Mylan or King. Any estimates contained in the analyses performed by Merrill Lynch are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than those suggested by such analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, such analyses and estimates are inherently subject to substantial uncertainty. In addition, as described above, Merrill Lynch’s opinion was among several factors taken into consideration by the Mylan board of directors in making its determination to approve the merger agreement and the merger. Consequently, Merrill Lynch’s analyses should not be viewed as determinative of the decision of the Mylan board of directors or Mylan management with respect to the fairness of the exchange ratio provided for in the merger agreement.

      In arriving at its opinion, Merrill Lynch, among other things, did the following:

  •  reviewed publicly available business and financial information relating to Mylan and King that Merrill Lynch deemed to be relevant;
 
  •  reviewed information relating to the business, earnings, cash flow, assets, liabilities and prospects of Mylan and King, including financial forecasts relating to Mylan and King prepared by Mylan management, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the merger furnished to Merrill Lynch by Mylan;
 
  •  conducted discussions with members of senior management of each of Mylan and King concerning the matters described in the first two clauses above, as well as their respective businesses and prospects both before and after giving effect to the merger and potential cost savings and related expenses and synergies expected to result from the merger;

38


Table of Contents

  •  reviewed the market prices and valuation multiples for Mylan common stock and King common stock and compared them with those of publicly traded companies that Merrill Lynch deemed to be relevant;
 
  •  reviewed the results of operations of Mylan and King and compared them with those of publicly traded companies that Merrill Lynch deemed to be relevant;
 
  •  compared the proposed financial terms of the merger with the financial terms of other transactions that Merrill Lynch deemed to be relevant;
 
  •  participated in discussions and negotiations among representatives of Mylan and King and their financial and legal advisors;
 
  •  reviewed the relative contributions of Mylan and King to selected operational metrics of the combined company based on financial forecasts and estimates prepared by Mylan management;
 
  •  reviewed the potential pro forma impact of the merger;
 
  •  reviewed the merger agreement; and
 
  •  reviewed other financial studies and analyses and took into account other matters as Merrill Lynch deemed necessary, including Merrill Lynch’s assessment of general economic, market and monetary conditions.

      In preparing its opinion, Merrill Lynch assumed and relied on the accuracy and completeness of all of the information supplied or otherwise made available to Merrill Lynch, discussed with or reviewed by or for Merrill Lynch or publicly available. Merrill Lynch did not assume any responsibility for independently verifying this information and did not undertake an independent evaluation or appraisal of any of the assets or liabilities of Mylan or King, nor was it furnished with any evaluations or appraisals. Merrill Lynch did not evaluate the solvency or fair value of Mylan or King under any state or federal laws relating to bankruptcy, insolvency or similar matters. In addition, Merrill Lynch did not assume any obligation to conduct any physical inspection of the properties or facilities of Mylan or King. With respect to the financial forecast information relating to Mylan and King and the information concerning potential cost savings and related expenses and synergies expected to result from the merger prepared by the management of Mylan and furnished to or discussed with Merrill Lynch by Mylan, Merrill Lynch assumed that they were reasonably prepared and reflected the best currently available estimates and judgments of Mylan management as to the expected future financial performance of Mylan or King, as the case may be, and the potential cost savings and related expenses and synergies expected to result from the merger. Merrill Lynch further assumed that the transaction will qualify as a reorganization for U.S. federal income tax purposes. Merrill Lynch assumed that each of Mylan, Summit Merger Corporation and King will comply with all material terms of the merger agreement and that the merger will be consummated in accordance with its terms without waiver, modification or amendment of any material term, condition or agreement.

      Merrill Lynch’s opinion is necessarily based upon market, economic and other conditions as they existed on, and on the information made available to Merrill Lynch as of, July 21, 2004. Merrill Lynch assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on Mylan, King or the contemplated benefits of the merger. Merrill Lynch did not express any opinion as to the prices at which Mylan common stock or King common stock will trade following the announcement of the merger or the price at which Mylan common stock will trade following consummation of the merger. Although Merrill Lynch evaluated the fairness, from a financial point of view, of the exchange ratio, Merrill Lynch was not requested to, and did not, recommend the specific consideration payable in the merger, which consideration was determined through negotiations between Mylan and King and approved by the Mylan board of directors. No other limitation was imposed on Merrill Lynch with respect to the investigations made or procedures followed by Merrill Lynch in rendering its opinion.

     Financial Analysis

      The following is a summary of the material analyses performed by Merrill Lynch in connection with its opinion to the Mylan board of directors dated July 23, 2004. Some of the financial analyses summarized below include information presented in tabular format. In order to understand fully Merrill Lynch’s financial analyses, the tables must be read together with the text of the summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data set forth below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Merrill Lynch’s financial analyses.

     Selected Comparable Companies Analysis

      Merrill Lynch compared financial, operating and stock market data of King to corresponding data of the following seven selected publicly traded companies in the specialty branded pharmaceuticals industry:

  •  Forest Laboratories, Inc.
  •  Shire Pharmaceuticals Group plc
  •  Endo Pharmaceuticals Holdings Inc.
  •  Biovail Corporation
  •  Medicis Pharmaceutical Corporation
  •  Warner Chilcott PLC
  •  Kos Pharmaceuticals, Inc.

      Merrill Lynch reviewed enterprise values, calculated as equity value, plus total debt, preferred stock and minority investments, less cash and cash equivalents, of the selected companies as multiples of calendar year 2004 estimated revenues and earnings before interest, taxes, depreciation and amortization, commonly referred to as EBITDA, and reviewed per share equity value of the selected companies as a multiple of calendar years 2004 and 2005 estimated earnings per share, referred to as EPS. All multiples were based on closing stock prices on July 21, 2004. Estimated financial data for the selected companies were based on First Call estimates as of July 21, 2004 and publicly available research analysts’ estimates. Estimated financial data for King were based on Mylan management’s estimates. Merrill Lynch then applied a range of selected multiples for these companies to corresponding data of King in order to derive an implied per share equity value reference range for King. This analysis indicated an implied per share equity value reference range for King of approximately $10.00 and $15.00, as compared to the per share equity value for King implied in the merger of $17.06 based on the exchange ratio of 0.9 provided for in the merger and the closing price of Mylan common stock on July 21, 2004.

      None of the selected companies is identical to King. Accordingly, an analysis of the results of the Selected Comparable Companies Analysis involves complex considerations and judgments concerning differences in financial and operating characteristics of the selected companies and other factors that could affect the public trading value of King and the selected companies.

Selected Comparable Acquisitions Analysis

      Using publicly available information, Merrill Lynch analyzed, among other things, the purchase prices and implied transaction multiples paid or proposed to be paid in the following selected transactions involving target companies in the specialty branded pharmaceuticals industry:

     
  Acquiror   Target
• Shire Pharmaceuticals Group plc
• King Pharmaceuticals, Inc.
• Galen Holdings Public Limited Company
• King Pharmaceuticals, Inc.
• Elan Corporation, plc
• Shire Pharmaceuticals Group plc
• Abbott Laboratories
• Johnson & Johnson
• Bristol-Myers Squibb Company
• King Pharmaceuticals, Inc.
• Axcan Pharma Inc.
  • Roberts Pharmaceutical Corporation
• Medco Research, Inc.
• Warner Chilcott PLC
• Jones Pharma Incorporated
• Dura Pharmaceuticals, Inc.
• BioChem Pharma Inc.
• Knoll (BASF)
• ALZA Corporation
• DuPont Pharmaceuticals Company
• Meridian Medical Technologies
• Salix Pharmaceuticals, Ltd.

      Merrill Lynch reviewed enterprise values of the selected transactions as multiples of one-year forward estimated revenues and EBITDA for the target companies. Merrill Lynch then applied a range of selected multiples derived from these transactions to fiscal year 2004 estimated revenues and EBITDA of King in order to derive an implied per share equity value reference range for King. All multiples for the selected transactions were based on estimated financial information available at the time of the announcement of the relevant transaction. Estimated financial data for King were based on Mylan management’s estimates. This analysis indicated an implied per share equity value reference range for King of approximately $13.20 to $27.35, as compared to the per share equity value for King implied in the merger of $17.06 based on the exchange ratio of 0.9 provided for in the merger and the closing price of Mylan common stock on July 21, 2004.

      No transaction used in the Selected Comparable Acquisitions Analysis is identical to the proposed merger. Accordingly, an analysis of the results of the Selected Comparable Acquisitions Analysis involves complex considerations of the companies involved and the transactions and other factors that could affect the acquisition value of the companies and King.

     Discounted Cash Flow Analysis

      Merrill Lynch estimated the present value of the stand-alone, unlevered, after-tax free cash flows that King could produce over the fiscal years 2005 through 2012 both before and after taking into account the potential synergies anticipated to result from the merger. Estimated financial data for King were based on Mylan management’s estimates. Ranges of terminal values were derived by applying terminal value multiples ranging from 9.0x to 11.0x to fiscal year 2012 estimated EBITDA for King. The free cash flows and terminal values were then discounted to present value using discount rates of 9.0% to 10.5% in order to derive implied per share equity value reference ranges for King. This analysis indicated an implied per share equity value reference range for King of approximately $14.37 to $18.13 before taking synergies into account, as compared to the per share equity value for King implied in the merger of $17.06 based on the exchange ratio of 0.9 provided for in the merger and the closing price of Mylan common stock on July 21, 2004. Merrill Lynch then estimated the present value of the potential synergies anticipated by Mylan management to result from the merger. Ranges of terminal values were derived by applying perpetuity growth rates ranging from 1.0% to 3.0% to fiscal year 2012 estimated free cash flows resulting from the potential synergies. The free cash flows and terminal values of the synergies were then discounted to present value using discount rates of 9.0% to 10.5% in order to derive an implied per share value range of the synergies of approximately $3.06 to $4.52.

     Relative Contribution Analysis

      Using estimated financial data for Mylan and King provided by Mylan management, Merrill Lynch analyzed the relative contributions of each of Mylan and King to the combined company’s revenue, EBITDA and cash net income (defined for purposes of this analysis as net income plus tax-effected amortization per Mylan management) for fiscal years 2004, 2005 and 2006. Merrill Lynch then computed exchange ratios implied by the ownership percentages of Mylan’s and King’s stockholders in the combined company implied by Mylan’s and King’s relative contributions for each operational metric observed. This analysis indicated implied exchange ratio reference ranges of approximately 0.576x to 0.766x based on revenue contribution, 0.714x to 1.152x based on EBITDA contribution and 0.751x to 1.150x based on cash net income contribution, as compared to the exchange ratio of 0.9 provided for in the merger.

     Other Factors

      In the course of preparing its opinion, Merrill Lynch also reviewed and considered other information and data, including the following:

  •  trading characteristics of Mylan and King;
 
  •  historical market prices for Mylan common stock and King common stock;
 
  •  the relationship between movements in Mylan common stock, movements in King common stock, movements in two composite indices comprised of selected specialty branded pharmaceutical companies and selected specialty generic pharmaceutical companies, respectively, and movements in the Standard and Poor’s 500 Index;
 
  •  the potential pro forma effects of the merger on Mylan’s estimated EPS and cash EPS (defined for purposes of Merrill Lynch’s review as EPS plus tax-effected amortization per share per Mylan management);
 
  •  financial, operating and stock market data of Mylan and selected publicly traded companies in the specialty generic pharmaceuticals industry; and
 
  •  selected research analysts’ reports on King, including stock price estimates of those analysts.

     Miscellaneous

      Pursuant to the terms of Merrill Lynch’s engagement, Mylan has agreed to pay Merrill Lynch (a) a fee of $2 million upon execution of the merger agreement and (b) a fee of $14.4 million upon consummation of the merger, from which any fees previously paid will be deducted. Mylan also has agreed to reimburse Merrill Lynch for reasonable expenses incurred by Merrill Lynch in performing its services and to indemnify Merrill Lynch and related persons and entities against liabilities, including liabilities under the U.S. federal securities laws, arising out of Merrill Lynch’s engagement.

      Mylan retained Merrill Lynch based upon Merrill Lynch’s experience and expertise. Merrill Lynch is an internationally recognized investment banking and advisory firm. Merrill Lynch, as part of its investment banking business, is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes.

      Merrill Lynch has, in the past, provided financial advisory and financing services to King unrelated to the merger and has received fees for the rendering of those services. In the ordinary course of business, Merrill Lynch and its affiliates may actively trade in the securities of Mylan and King for their own accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

King’s Reasons for the Merger

      The King board of directors has unanimously (with one director absent) determined that the terms of the merger are advisable and fair to and in the best interest of King and its shareholders and has unanimously (with one director absent) approved the merger agreement and the merger and recommends that the King shareholders vote “FOR” the proposal to approve and adopt the merger agreement and to approve the merger.

      In reaching that determination, the King board considered the information provided to it, analyzed the terms of the merger agreement, and considered a variety of factors, a number of which are summarized below. The King board of directors consulted with senior members of King’s management and its legal, financial and other advisors regarding the strategic and operational aspects of the merger and the results of the due diligence efforts undertaken by King. The King board consulted with representatives of Goldman Sachs, financial advisor to King, regarding financial aspects of Mylan’s business and future prospects, as well as the fairness to King’s shareholders, from a financial point of view, of the proposed ratio for exchanging shares of King common stock for shares of Mylan common stock. The King board also considered the prospects for generic pharmaceutical companies in general and Mylan in particular. The King board also consulted with representatives of Cravath, outside counsel to King, regarding the duties of the members of the board of directors and the terms of the merger agreement.

      After careful consideration of the premium available to King shareholders and the other factors described below, the King board of directors has concluded that the merger is in the best interests of King and King’s shareholders.

      The King board considered the extent to which the exchange of shares of King common stock for shares of Mylan common stock would provide holders of King common stock with the opportunity to have a continuing equity participation in the combined company. The proposed exchange ratio would result in holders of King common stock receiving a significant equity stake in the combined company, equal to approximately [44]% of the outstanding common stock of the combined company after completion of the merger.

      The exchange of shares of Mylan common stock for each outstanding share of King common stock represented an attractive premium for King shareholders of:

  •  approximately 61.8% over the closing price of King common stock on the last trading day prior to the announcement of the merger agreement, based on the 0.9 exchange ratio and the closing price of Mylan common stock on the same day; and
 
  •  approximately 34.3% over the average closing price of King common stock during the six months prior to the announcement of the merger, based on the 0.9 exchange ratio and the average closing price of Mylan common stock during the same time period.

      The King board also considered the fact that the stock-for-stock exchange will result in a reduction in the premium to be received by King shareholders in the merger to the extent that the trading price of Mylan common stock falls prior to the completion of the merger.

      The King board of directors considered the strategic position that may result from a business combination transaction such as the merger, compared to King’s prospects on a stand-alone basis. The King board considered and evaluated a number of strategic alternatives that King could pursue on an independent basis, including the divestiture of existing King products, the acquisition of other pharmaceutical companies, pharmaceutical products, rights to potential pharmaceutical products under development and certain other strategic commercial transactions. The board also considered King’s ability to successfully complete those strategic alternatives.

      The King board considered the potential for the businesses of King and Mylan to complement each other. Mylan operates primarily in the generic segment of the U.S. pharmaceuticals industry with

43


Table of Contents

significant expertise in manufacturing, supply chain management and intellectual property management. King has a substantial sales and marketing infrastructure and experience in the marketing and promotion of branded prescription pharmaceutical products. The King board considered the extent to which the combined company may have the ability to leverage opportunities in both the generic and branded segments of the U.S. pharmaceuticals industry. The King board also considered the extent to which the combined company’s product portfolio may strengthen the financial condition of both King and Mylan. The combined company would have significant operations in the generic as well as branded pharmaceutical segments. The King board made note of Mylan’s proprietary product nebivolol, a beta blocker for the treatment of hypertension, the NDA for which was accepted for filing in June by the FDA.

      In reaching its decision to approve and adopt the merger agreement and approve the merger, and to recommend that King shareholders vote to approve and adopt the merger agreement and approve the merger, the King board of directors also considered a variety of other factors, a number of which are summarized below:

  •  the business, financial condition and results of operations of each of King and Mylan, including Mylan’s balance sheet position as of June 30, 2004;
 
  •  current and historical trading prices of King and Mylan common stock relative to each other, relative to historical trading prices of other industry participants and relative to general market and sector indices;
 
  •  current industry, economic and market conditions;
 
  •  the likelihood that the regulatory approvals needed to complete the transaction will be obtained;
 
  •  the ability to complete the merger and to have the exchange of shares of King common stock for shares of Mylan common stock as “tax-free” transactions for U.S. Federal income tax purposes;
 
  •  Mylan’s reputation and the quality and experience of its management;
 
  •  the expected opportunities available to King employees as part of a larger, well-diversified organization following the merger;
 
  •  the provisions of the merger agreement regarding the compensation and benefits to be provided to King employees following the merger, including through the employee compensation and benefit programs of Mylan;
 
  •  the analyses, presentations and opinion of Goldman Sachs delivered to King’s board of directors to the effect that, as of July 23, 2004 and based upon and subject to the factors and assumptions set forth in the opinion, the 0.9 exchange ratio pursuant to the merger agreement was fair from a financial point of view to the holders of outstanding shares of King common stock (the written opinion of Goldman Sachs is attached as Annex C to this joint proxy statement/ prospectus);
 
  •  the prospects for generic pharmaceutical companies in general and Mylan in particular;
 
  •  the risk that the forecasts that were prepared by management and shared with the King board and King’s financial advisors may not be achieved; and
 
  •  the terms and conditions of the merger agreement, including the right of the King board of directors to respond to, evaluate and negotiate certain other business combination proposals, and to terminate the merger agreement prior to its approval by King shareholders in the exercise of its fiduciary duties in connection with a superior proposal for a business combination or acquisition of King (see the section entitled “The Merger Agreement” beginning on page [75]).

44


Table of Contents

      In addition to considering these factors, the King board of directors also considered potential drawbacks or risks relating to the merger, including:

  •  the historic volatility of the trading price of Mylan common stock and the absence of provisions in the merger agreement that limit the effect of declines in the trading price of Mylan common stock prior to the completion of the merger on the value of the premium and consideration received by holders of King common stock in the merger;
 
  •  the fact that Mylan’s board of directors would control the combined company and is not required or expected to include any current members of King’s board;
 
  •  the restrictions on the conduct of King’s business during the period between signing of the merger agreement and the completion of the merger or the termination of the merger agreement, which could delay or prevent King from pursuing business opportunities that may arise prior to the merger;
 
  •  the expenses, costs and risks associated with integrating the businesses of Mylan and King following the merger, and the fact that Mylan has not previously completed a large acquisition such as the merger;
 
  •  the risks and costs to King if the merger is not consummated (including the diversion of management attention and employee attrition and the potential effect on business and customer relationships);
 
  •  the business, financial, operational and other risks associated with King continuing to operate as an independent company;
 
  •  the business, financial, operational and other risks associated with the Mylan common stock that King shareholders will receive pursuant to the merger; and
 
  •  the possibility that the termination fee payable upon termination of the merger agreement in connection with a superior proposal for a business combination or acquisition of King may discourage other parties that may otherwise have an interest in a business combination with, or an acquisition of, King (see the section entitled “The Merger Agreement — Termination Fee” beginning on page [89]).

      Further, the King board of directors was aware of and considered the interests of executive officers and directors of King described under “— Interests of King Directors and Executive Officers in the Merger” beginning on page [64].

      The foregoing discussion addresses material information and factors considered by the King board of directors in its consideration of the merger and the merger agreement, including factors that support the merger as well as those that may weigh against it. In view of the variety and amount of information considered, the King board did not find it practicable to and did not make specific assessments of, quantify or otherwise assign relative weights to the factors considered in reaching its determination. Individual members of the King board may have given different weights to and had different evaluations of the various factors. However, as the determination to approve and adopt the merger agreement and approve the merger was made after consideration of all of the factors in the aggregate, the King board did not determine whether any particular factor was favorable or unfavorable to its ultimate determination.

Recommendation of the King Board of Directors

      At a meeting of the King board of directors on July 23, 2004, the board, after consulting with its advisors and carefully considering the reasons and factors summarized above under “— King Reasons for the Merger,” unanimously (with one director absent) determined that the merger agreement and the merger are advisable and in the best interests of King and King’s shareholders, and unanimously (with one

45


Table of Contents

director absent) approved and adopted the merger agreement and approved the merger. Accordingly, the King board of directors recommends that King shareholders vote “FOR” the proposal to approve and adopt the merger agreement and approve the merger.

Opinion of Financial Advisor to King

      Goldman Sachs delivered an opinion to King’s board of directors, to the effect that, as of July 23, 2004 and based upon and subject to the factors and assumptions set forth in the opinion, the 0.9 exchange ratio pursuant to the merger agreement was fair from a financial point of view to the holders of outstanding shares of King common stock. King has not obtained an updated opinion as of the date of this joint proxy statement/ prospectus from Goldman Sachs. The Goldman Sachs opinion does not speak as of any date other than the date of the opinion.

      The full text of the written opinion of Goldman Sachs, dated July 23, 2004, which sets forth the assumptions made, procedures followed, matters considered, and limitations on the review undertaken in connection with the opinion, is attached as Annex C. Goldman Sachs provided its opinion for the information and assistance of King’s board of directors in connection with its consideration of the merger. Goldman Sachs’ opinion is not a recommendation as to how any holder of King common stock should vote with respect to the merger.

      In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

  •  the merger agreement;
 
  •  annual reports to shareholders and Annual Reports on Form 10-K of King for the five fiscal years ended December 31, 2003;
 
  •  annual reports to shareholders and Annual Reports on Form 10-K of Mylan for the five fiscal years ended March 31, 2004;
 
  •  interim reports to shareholders and Quarterly Reports on Form 10-Q of King and Mylan;
 
  •  other communications from King and Mylan to their respective shareholders;
 
  •  internal financial analyses and forecasts for King prepared by its management, referred to as the King Forecasts;
 
  •  internal financial analyses and forecasts for Mylan prepared by its management, as adjusted for fiscal years after the fiscal year ending March 31, 2006 by management of King, referred to as the Mylan Forecasts; and
 
  •  cost and operational synergies estimated by the managements of King and Mylan to result from the merger.

      Goldman Sachs also held discussions with members of the senior managements of King and Mylan regarding their assessment of the strategic rationale for, and the potential benefits of, the merger and the past and current business operations, financial condition and future prospects of their respective companies.

      In addition, Goldman Sachs:

  •  reviewed the reported price and trading activity for the King common stock and Mylan common stock;
 
  •  compared financial and stock market information for King and Mylan with similar information for other companies the securities of which are publicly traded;

46


Table of Contents

  •  reviewed the financial terms of certain recent business combinations in the specialty pharmaceuticals industry specifically and in other industries generally; and
 
  •  performed such other studies and analyses, and considered such other factors, as Goldman Sachs considered appropriate.

      Goldman Sachs relied upon the accuracy and completeness of all of the financial, accounting and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of rendering its opinion. In that regard, Goldman Sachs assumed with the consent of King’s board of directors that the King Forecasts and Mylan Forecasts, including in each case the assumptions therein with respect to the expected financial impact of patent related matters and other developments that could impact the pricing of, and demand for, the products of King and Mylan, were reasonably prepared on a basis reflecting the best currently available estimates and judgments of King and Mylan, as applicable, and that the estimated cost and operational synergies reflect the best currently available estimates and judgments of King and Mylan.

      In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance sheet assets and liabilities) of King or Mylan or any of their respective subsidiaries and Goldman Sachs was not furnished with any such evaluation or appraisal. Goldman Sachs also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on King or Mylan or on the expected benefits of the merger in any way meaningful to Goldman Sachs’ analysis. Goldman Sachs’ opinion did not address the underlying business decision of King to engage in the merger nor did Goldman Sachs express any opinion as to the prices at which the shares of King or Mylan common stock will trade at any time. With the consent of King’s board of directors, Goldman Sachs relied upon the advice King received from its legal counsel and accounting and tax advisors as to all legal matters, including intellectual property and regulatory matters, and accounting and tax matters in connection with the merger.

      The following is a summary of the material financial analyses presented by Goldman Sachs to King’s board of directors in connection with rendering its opinion. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs. The order of analyses described does not represent the relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs’ financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before July 21, 2004, and is not necessarily indicative of current market conditions.

Analysis of Illustrative Present Values Based on Hypothetical Future Stock Prices

King Common Stock

      Goldman Sachs calculated implied present values of a share of common stock of King based on hypothetical future share prices for King common stock derived using King management’s estimates of King’s earnings per share, or EPS, for 2008. For purposes of this analysis, Goldman Sachs calculated the hypothetical future share prices for King common stock by multiplying the estimate of 2008 EPS for King by hypothetical forward price-to-earnings, or P/ E, ratios ranging from 10.0x to 16.0x. Using discount rates ranging from 10.0% to 15.0% (reflecting a range of hypothetical cost of equity), Goldman Sachs derived illustrative implied present values for a share of King common stock ranging from $6.80 to $13.00.

Mylan Common Stock

      Goldman Sachs also calculated implied present values of a share of common stock of Mylan based on hypothetical future share prices for Mylan common stock derived using calendar year 2008 EPS estimates for Mylan based on the Mylan Forecasts. For purposes of this analysis, Goldman Sachs calculated the hypothetical future share prices for Mylan common stock by multiplying the estimate of calendar year 2008 EPS for Mylan by hypothetical forward P/ E ratios ranging from 14.0x to 20.0x. Using discount rates ranging from 10.0% to 15.0% (reflecting a range of hypothetical cost of equity), Goldman Sachs derived illustrative implied present values for a share of Mylan common stock ranging from $16.26 to $27.74.

 
Pro Forma Combined Company Common Stock

      Goldman Sachs also calculated implied values of the Mylan common stock to be received in respect of each share of King common stock pursuant to the merger. Goldman Sachs applied hypothetical calendar year 2005 forward P/ E multiples for the combined company to pro forma U.S. GAAP, EPS estimates and cash EPS estimates, which was adjusted to exclude the impact of transaction-related amortization, for the combined company for the 2005 calendar year based on the King Forecasts, the Mylan Forecasts, and estimates of cost and operational synergies prepared by the managements of King and Mylan for the 2005 calendar year. Based on a forward P/ E multiple range of 11.0x to 17.0x, the analysis resulted in implied pro forma value indications for each share of King common stock, based on the 0.9 exchange ratio, ranging from $12.32 to $19.03 using the U.S. GAAP EPS estimates and $12.87 to $19.88 using the cash EPS estimates.

 
Discounted Cash Flow Analysis

King Common Stock

      Goldman Sachs performed a discounted cash flow analysis to determine illustrative implied present values per share of King common stock using the King Forecasts through the fiscal year ending December 31, 2008. Using discount rates ranging from 10% to 12% (representing the range of weighted average cost of capital for comparable specialty pharmaceuticals companies), Goldman Sachs derived implied present values ranging from $8.55 to $11.80 per share of King common stock by discounting to present values the expected free cash flows of King over the period August 1, 2004 through December 31, 2008 and discounting to present values the terminal values at December 31, 2008. The terminal values were calculated in two parts. The terminal value for Altace® was calculated using a 0.25x multiple of 2008 Altace® revenue. The terminal values for the remainder of the business were calculated by multiplying terminal EBIT, or earnings before interest and income tax, net of Altace® contribution, by terminal EBIT multiples ranging from 7.0x to 11.0x.

Mylan Common Stock

      Goldman Sachs performed a discounted cash flow analysis to determine illustrative implied present values per share of Mylan common stock using the Mylan Forecasts. Using discount rates ranging from 10.0% to 12.0% (representing the range of weighted average cost of capital for comparable specialty

48


Table of Contents

pharmaceuticals companies), Goldman Sachs derived implied present values ranging from $19.40 to $29.07 per share of Mylan common stock by discounting to present values the expected free cash flows of Mylan over the period from August 1, 2004 through March 31, 2009 and discounting to present value the terminal value at March 31, 2009. The terminal values for the business was calculated by multiplying terminal EBIT by terminal multiples ranging from 7.0x to 11.0x.
 
Pro Forma Combined Company Common Stock

      Goldman Sachs also performed a discounted cash flow analysis to determine illustrative implied present values of the Mylan common stock to be received in respect of each share of King common stock pursuant to the merger, using the King Forecasts; Mylan Forecasts; and estimates of cost and operational synergies prepared by the managements of King and Mylan. Goldman Sachs used discount rates ranging from 10% to 12% (representing the range of weighted average cost of capital for comparable specialty pharmaceuticals companies) and calculated terminal values in two parts for King. The terminal value for Altace® was calculated using a 0.25x multiple of 2008 Altace® revenue. The terminal values for the remainder of the business were calculated by multiplying terminal EBIT, net of Altace® contribution, by terminal EBIT multiples ranging from 7.0x to 11.0x. Goldman Sachs derived implied present values ranging from $15.23 to $22.51 for the Mylan common stock to be received in respect of each share of King common stock pursuant to the merger.

 
Historical Exchange Ratio Analysis

      Goldman Sachs reviewed the implied exchange ratios derived by dividing the average closing price of King common stock by the average closing price of Mylan common stock over one-week, one-, three-, six-month and one-year periods ending July 21, 2004. Goldman Sachs also reviewed the implied exchange ratios derived by dividing the closing prices of King common stock by the closing prices of Mylan common stock on July 21, 2004, on the last trading day of each of the four most recently reported fiscal quarters ended prior to July 21, 2004, on February 26, 2004, the date on which the highest implied exchange ratio occurred during the 52-week period ended July 21, 2004, and on December 1, 2003, the date on which the lowest implied exchange ratio occurred during the 52-week period ended July 21, 2004. The result of these ratio calculations is reflected in the following tables.

Historical Premium Analysis

      Goldman Sachs calculated that the $17.06 implied merger consideration price, which is based upon the $18.95 closing price for Mylan common stock as of July 21, 2004 and the 0.9 exchange ratio, represented a premium of 62.7% over the $10.48 closing price for shares of King common stock on July 21, 2004. On September 2, 2004, the last sale price of Mylan common stock prior to the date of this joint proxy statement/prospectus, as reported on the NYSE Composite Transactions Tape, was $17.44 per share.

      Goldman Sachs calculated the implied merger price derived by multiplying the average closing price of Mylan common stock over the one-week, one-, three-, six-month and one-year periods ended July 21, 2004, times the 0.9 exchange ratio. Goldman Sachs compared the implied merger price to the average closing price of the King common stock over each of the one-week, one-, three-, six-month and one-year periods ended July 21, 2004 to calculate the implied premium.

      Goldman Sachs also calculated the implied merger price derived by multiplying the average closing prices of Mylan common stock on the last trading day of each of the four most recently reported fiscal quarters ended prior to July 21, 2004 times the 0.9 exchange ratio. Goldman Sachs compared the implied merger price to the closing prices of King common stock on the last trading day of each of the four most recently reported fiscal quarters ended prior to July 21, 2004 to calculate the implied premium. Goldman Sachs also calculated the implied merger price derived by multiplying the closing prices of Mylan common stock on February 26, 2004, the date on which the highest implied exchange ratio occurred during the 52-week period ended July 21, 2004 and on December 1, 2003, the date on which the lowest implied exchange ratio occurred during the 52-week period ended July 21, 2004, times the 0.9 exchange ratio. Goldman Sachs compared those implied merger prices to the closing prices of King common stock on February 26, 2004 and December 1, 2003, respectively, to calculate the implied premiums.

Contribution Analysis

      For the calendar years ending 2004, 2005, 2006, and 2007, Goldman Sachs calculated

  •  the hypothetical relative contributions of King and Mylan to the estimated revenues, operating income and net income of the combined company, and

50


Table of Contents

  •  implied equity contributions of King and Mylan based upon estimated revenues, operating income and net income of the combined company as adjusted for the net debt positions of King and Mylan.

      For purposes of the foregoing calculations, Goldman Sachs utilized the closing prices for shares of common stock of King and Mylan, respectively, on July 21, 2004, the King Forecasts, the Mylan Forecasts, and the 0.9 exchange ratio. Goldman Sachs used net debt information for King and Mylan based on their latest publicly available filing prior to July 21, 2004 for calculating King’s and Mylan’s implied equity contribution. Net debt is defined as total indebtedness less cash.

      The results of the Goldman Sachs calculations are as follows:

      Goldman Sachs also conducted a contribution analysis of King and Mylan using discounted cash flow methodologies. Using projections provided by management of King and Mylan without taking into account estimates of cost and operational synergies, Goldman Sachs derived hypothetical equity contribution percentages for King and Mylan assuming a discount rate of 11% and terminal EBIT multiples for King and Mylan ranging from 7.0x to 11.0x. For King, the terminal values were calculated in two parts. The terminal value for Altace® was calculated using a 0.25x multiple of 2008 Altace® revenue. The terminal values for the remainder of the business were calculated by multiplying terminal EBIT, net of Altace® contribution, by terminal EBIT multiples ranging from 7.0x to 11.0x. Using these methodologies, terminal value multiples, and discount rate, Goldman Sachs calculated hypothetical equity value contribution percentages for King ranging from 21.2% to 32.9%.

      Goldman Sachs noted that, based on the 0.9 exchange ratio, the fully diluted King shareholder ownership of the combined company was approximately 44.2%.

      Goldman Sachs analyzed the pro forma impact of the merger on both U.S. GAAP and cash EPS from the point of view of the holders of King common stock (based on the 0.9 exchange ratio). Based on the closing stock prices of King common stock and Mylan common stock as of July 21, 2004, the number of shares and options of King and Mylan outstanding as disclosed in publicly available data as of March 31, 2004, the King Forecasts and the Mylan Forecasts, this analysis indicated that the merger would be accretive to U.S. GAAP and cash EPS in 2005 from the point of view of the holders of King

common stock and more accretive to them in 2006. The analysis further indicated that, for both 2005 and 2006, the merger would be more accretive from the point of view of the holders of King common stock to U.S. GAAP and cash EPS when estimates of cost and operational synergies prepared by the managements of King and Mylan are taken into consideration.
 
Comparison of Selected Specialty Pharmaceuticals Companies

      Goldman Sachs reviewed and compared certain financial information and public market multiples for King and Mylan to corresponding financial information and public market multiples for the following selected specialty pharmaceuticals companies:

             
Branded Pharmaceuticals Companies Generic Pharmaceuticals Companies


  Allergan, Inc.     Alpharma Inc.
  Alcon, Inc.     Andrx Corporation
  Biovail Corporation     Barr Pharmaceuticals, Inc.
  Elan Corporation, plc     Eon Labs, Inc.
  Endo Pharmaceuticals Holdings Inc.     Ivax Corporation

  Medicis Pharmaceutical Company     Par Pharmaceutical Companies, Inc.
  Shire Pharmaceuticals Group plc     Taro Pharmaceutical Industries Ltd.
  Valeant Pharmaceuticals International     Teva Pharmaceutical Industries Limited
          Watson Pharmaceuticals, Inc.

      Although none of the selected companies is directly comparable to King or Mylan, the companies included were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to certain operations of King or Mylan.

      Goldman Sachs also calculated and compared various financial multiples based on historical financial data available as of July 21, 2004 and projected earnings per share, or EPS, based on Institutional Brokerage Estimate System, or IBES, estimates. The multiples were calculated by using the closing stock price as of July 21, 2004. The multiples of King, Mylan and the selected specialty pharmaceuticals companies were based on the most recent publicly available information.

      Goldman Sachs calculated and compared the following results for King, Mylan and the selected companies:

  •  enterprise value as a multiple of EBIT for the latest twelve months based on publicly available data disclosed as of July 21, 2004;
 
  •  the July 21, 2004 closing stock price as a multiple of estimated EPS for 2004, referred to as the 2004 P/ E multiple, and as a multiple of estimated EPS for 2005, referred to as the 2005 P/ E multiple, based on IBES; and
 
  •  the 2004 P/ E multiple as a multiple of the estimated five-year EPS compounded annual growth rate, referred to as the 5-Year EPS CAGR, based on IBES.

Selected Historical Transactions Analysis

      Goldman Sachs analyzed certain publicly available information for the following announced transactions involving companies in the specialty pharmaceuticals industry (Target/ Acquirer — Announcement Date):

  •  Sicor Inc./ Teva Pharmaceutical Industries Ltd. — October 31, 2003
 
  •  DuPont Pharmaceuticals Co./ Bristol-Myers Squibb Co. — June 7, 2001
 
  •  Alza Corp./ Johnson & Johnson — March 27, 2001
 
  •  Knoll Pharmaceuticals/ Abbott Laboratories — December 15, 2000
 
  •  BioChem Pharma Inc./ Shire Pharmaceuticals Group plc — December 11, 2000
 
  •  Dura Pharmaceuticals, Inc./ Elan Corporation, PLC — September 11, 2000
 
  •  Jones Pharma Incorporated/ King Pharmaceuticals, Inc. — July 13, 2000

      Goldman Sachs calculated and compared the following multiples and premia for each of the selected transactions:

  •  the levered aggregate consideration as a multiple of sales, EBIT and EBITDA, or earnings before interest, income tax, depreciation and amortization for the twelve month period prior to the announcement, referred to as the LTM period; and
 
  •  the premium over the target’s share price one day, one week and one month prior to announcement reflected by the announced per-share transaction price.

      For purposes of this analysis, the levered aggregate consideration for each target was calculated by multiplying the announced per share transaction price by the number of that company’s fully diluted outstanding shares as disclosed in the company’s most recent filings prior to the announcement of the applicable transaction and adding to that result the company’s net debt as disclosed in the company’s most recent filings prior to the announcement of the applicable transaction.

Analysis of Merger Multiples for Proposed Transaction

      Goldman Sachs performed an analysis of the merger based on publicly available historical information and the King Forecasts and the 0.9 exchange ratio. Using the closing price for the Mylan common stock as of July 21, 2004, Goldman Sachs calculated for King the implied total equity consideration (on a fully-diluted basis), an implied enterprise value, the ratio of enterprise value to revenues for the 2004 and 2005 calendar years, the ratio of enterprise value to EBITDA for the 2004 and 2005 calendar years, the ratio of enterprise value to EBIT for the 2004 and 2005 calendar years and the ratio of equity consideration (on a fully-diluted basis) to net income for the 2004 and 2005 calendar years.

      The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all the analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all the analyses. No company or transaction used in the above analyses as a comparison is directly comparable to King or Mylan or the merger.

      Goldman Sachs prepared these analyses for purposes of Goldman Sachs’ providing its opinion to King’s board of directors as to the fairness from a financial point of view to the holders of the outstanding shares of King common stock of the 0.9 exchange ratio pursuant to the merger agreement. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses.

Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of King, Mylan, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast. As described above, Goldman Sachs’ opinion to King’s board of directors was one of many factors taken into consideration by King’s board of directors in making its determination to approve the merger agreement.

      Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Goldman Sachs acted as financial advisor to King in connection with, and participated in certain of the negotiations leading to, the transaction contemplated by the merger agreement. In addition, Goldman Sachs has provided investment banking services to King from time to time, including having acted as:

  •  its financial advisor in connection with its acquisition of Skelaxin® and Sonata®, pharmaceutical products, from Elan Corporation in June 2003;
 
  •  its financial advisor in connection with its acquisition of the Ortho-Prefest® pharmaceutical product from Ortho-McNeil Pharmaceutical, Corp., a subsidiary of Johnson & Johnson, in May 2002;
 
  •  co-lead manager of the private placement of $345,000,000 aggregate principal amount of the Company’s 2 3/4% Convertible Debentures due November 15, 2021 in November 2001;
 
  •  co-lead manager of a public offering of 22,492,000 shares of King’s common stock in November 2001; and
 
  •  agent in connection with repurchases by King of shares of its common stock from time to time.

      Goldman Sachs also acted as agent for Mylan in connection with repurchases by Mylan of its common stock from time to time. Goldman Sachs also may provide investment banking services to King and Mylan in the future. In connection with the above-described investment banking services Goldman Sachs has received, and may receive, compensation.

      Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide these services to King, Mylan and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of King and Mylan for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

      King selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement, dated February 19, 2004, King engaged Goldman Sachs to act as its financial advisor in connection with a possible significant strategic transaction. Pursuant to the terms of this letter agreement, Goldman Sachs will receive a transaction fee of 0.40% of the aggregate consideration in connection with the merger, which fee calculated as of the date of this joint proxy statement/prospectus is approximately $16.5 million and is contingent upon completion of the merger. King has also agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs against various liabilities, including various liabilities under the federal securities laws.

Interests of King Directors and Executive Officers in the Merger

      In considering the recommendation of the King board of directors to vote for the proposal to approve and adopt the merger agreement and approve the merger, shareholders of King should be aware that

55


Table of Contents

members of King’s board of directors and King’s executive officers have agreements or arrangements that provide them with interests in the merger and merger agreement that are different from, or in addition to, the interests of King and King’s shareholders generally. The King board of directors was aware of these agreements and arrangements during its deliberations on the merits of the merger and merger agreement and in determining to recommend that the shareholders of King vote for the proposal to approve and adopt the merger agreement and approve the merger.
 
Stock Options

      Following the completion of the merger, upon the termination of employment of any King employee who holds King stock options (other than a termination for cause), including King’s executive officers, stock options granted under King’s 1997 Incentive and Nonqualified Stock Option Plan for Employees that are outstanding at the time of the merger and held by that employee would, to the extent not exercisable at the time of the employee’s termination of employment, accelerate and become fully exercisable. The stock options would generally remain exercisable for a period of three months following the termination of employment.

      In addition, upon the resignation of King’s non-employee directors from King’s board of directors, which will occur upon the completion of the merger, stock options that are not exercisable and are held by those non-employee directors will become fully exercisable and will remain exercisable for a period of one year following the resignation of those directors.

      As of September 1, 2004, the directors and executive officers of King held the following King stock options:

      As described below under “King Offer Letter — Brian Markison,” if certain performance criteria are satisfied during 2004 Mr. Markison will receive a bonus in the amount of 60-75% of his annual base salary in lieu of the bonus described above.

 
      King Offer Letter — Brian Markison

      On July 15, 2004, Mr. Markison accepted the terms of an offer letter from King pursuant to which he was named the President and Chief Executive Officer of King. Pursuant to the offer letter, Mr. Markison receives an annual salary of $750,000 and is eligible for an annual bonus if certain annual performance criteria are satisfied. His 2004 target bonus will be prorated based on his commencement of employment during 2004, and the level of his 2004 bonus opportunity will be based upon a weighted-average percentage of base salary that reflects the portion of 2004 during which Mr. Markison served as King’s chief operating officer and the portion of 2004 during which he served as King’s acting chief executive officer or chief executive officer. The target bonus percentage for the period he served as chief operating officer is 60% and the target bonus percentage for the period he served as acting chief executive officer or chief executive officer is 75%, yielding a target bonus of $456,475 for 2004. Mr. Markison’s 2005 target bonus will be equal to 75% of his base salary.

      Pursuant to the offer letter, Mr. Markison was also granted a stock option under King’s 1997 Incentive and Nonqualified Stock Option Plan for Employees to purchase 250,000 shares of King common stock at an exercise price of $10.67 per share. One-half of the shares subject to the stock option will become exercisable on each of the second and third anniversaries of the grant date.

      The offer letter provides that if Mr. Markison’s employment is terminated “without cause,” or if he resigns for “good reason,” prior to the completion of the merger, he will be entitled to a severance payment equal to two times the sum of his annual base salary and target bonus, continued health and welfare benefits for two years following the termination of his employment and full vesting of stock options granted to him under King’s 1997 Incentive and Nonqualified Stock Option Plan for Employees. In the event that Mr. Markison is subject to an excise tax because any payments or benefits are deemed to be “excess parachute payments” within the meaning of Section 280G of the Code, he will be entitled to a tax gross-up payment that restores him to the same after-tax position that he would have been in had the excise tax not been imposed.

      The offer letter provides for increased severance benefits in the event of a change of control of King. If Mr. Markison’s employment is terminated “without cause,” or if he resigns for “good reason,” within the two-year period following the completion of the merger, the severance payment described above will be increased to three times the sum of his annual base salary and target bonus, the continuation of health and welfare benefits will be extended to three years following the termination of his employment, and he will be entitled to the full vesting of stock options granted to him under King’s 1997 Incentive and Nonqualified Stock Option Plan for Employees, as well as the tax gross-up payment described above. If Mr. Markison’s employment is terminated “without cause,” or if he resigns for “good reason,” following the second anniversary of the completion of the merger, his severance benefits will revert to those available

57


Table of Contents

prior to the merger. Severance payments and benefits provided to Mr. Markison pursuant to the offer letter supersede any other severance arrangements Mr. Markison has with King.

      For purposes of the offer letter, “good reason” means a reduction of his compensation, benefits, responsibilities, duties, authority, reporting relationships, title and/or position (in each case other than his position, if any, as a director of King or any subsidiary or as an officer of any subsidiary), unless other similarly situated senior executives of King are required to accept a similar reduction. Mr. Markison’s resignation would also be for “good reason” if (1) the company requires him to relocate to a location more than fifty miles from his current residence, (2) the company fails to pay him any compensation or benefits or (3) the company commits a material breach of the terms of the employment letter. Good reason will not be deemed triggered merely as a result of King’s ceasing to be a publicly traded company in connection with a change in control or as a result of King’s becoming a subsidiary of another company.

      Assuming Mr. Markison’s employment is terminated “without cause,” or he resigns for “good reason,” during the fourth quarter of calendar year 2004, and based on Mr. Markison’s current annual base salary of $750,000, Mr. Markison would be entitled to receive a cash severance payment of approximately $2,412,950 if the completion of the merger had not yet occurred prior to his termination, compared to a cash severance payment of approximately $3,619,425 if the merger had already been completed prior to his termination, yielding a potential increase in cash severance payment of approximately $1,206,475 as a result of a change of control of King. In addition, assuming a cash severance payment of approximately $3,619,425 following a change of control, and assuming a change of control takes place on November 15, 2004, Mr. Markison would be entitled to receive an excise tax gross-up payment of approximately $1,650,716. The estimated cash severance amount and excise tax gross-up for Mr. Markison do not reflect any amounts related to non-cash severance benefits, such as the value of continued health and welfare benefits or stock option acceleration, or any other applicable payments.

 
      Severance Benefits

      The merger agreement requires Mylan to provide, for a period of two years following the completion of the merger, severance benefits to continuing employees that are no less favorable than those provided under King’s existing severance policy. Because King’s existing severance policy provides for enhanced severance benefits following a change of control of King, the merger would result in enhanced severance benefits becoming payable to King’s executive officers if their employment is terminated “without cause,” or if they resign for “good reason,” following the completion of the merger.

      Under King’s existing severance policy, King’s chief executive officer is entitled to enhanced severance in the event of a change of control. However, as described above under “King Offer Letter — Brian Markison,” King’s current chief executive officer, Mr. Markison, is party to an offer letter with King that provides severance arrangements in lieu of those under King’s existing severance policy.

      Under King’s existing severance policy, if any of the next three highest ranking King executives is terminated “without cause” prior to a change of control, he or she would be entitled to a severance payment equal to 1.5 times the sum of his or her annual salary and target bonus, as well as continued health and welfare benefits for 1.5 years following the termination of his or her employment. Following the completion of the merger, this severance payment is increased to two times the sum of the executive’s annual salary and target bonus, and continued health and welfare benefits are extended to two years following the termination of the executive’s employment. In addition, the enhanced severance benefits become available if the executive resigns for “good reason” following the completion of the merger. In the event that any of the next three highest ranking King executives is subject to an excise tax because any payments or benefits are deemed to be “excess parachute payments” within the meaning of Section 280G of the Code, then the executive will be entitled to a tax gross-up payment that restores the executive to the same after-tax position that the executive would have been in had the excise tax not been imposed.

      Under King’s existing severance policy, if any executive vice president of King is terminated “without cause” prior to a change of control, he or she would be entitled to a severance payment equal to one times the sum of his or her annual salary and target bonus, as well as continued health and welfare benefits for

58


Table of Contents

one year following the termination of his or her employment. Following the completion of the merger, this severance payment is increased to two times the sum of the executive’s annual salary and target bonus, and continued health and welfare benefits are extended to two years following the termination of the executive’s employment. In addition, the enhanced severance benefits become available if the executive resigns for “good reason” following the completion of the merger.

      For purposes of King’s existing severance policy, termination by the executive for “good reason” includes, generally, a failure by King to promptly pay compensation; an unauthorized reduction in compensation; a demotion or diminution of duties; a change in employment requirements that subjects the executive to an unfair change of circumstances; a breach of contract; or requiring the executive to move.

      The following table lists the expected cash severance payments that Messrs. Lattanzi, Bellamy and Brouillette would receive, assuming they are terminated “without cause,” or resign for “good reason,” immediately following the completion of the merger. The calculation of the executive’s cash severance payment is based on the executive’s annual base salary and the executive’s target bonus under King’s Executive Management Incentive Plan, in each case as of September 1, 2004. The estimated cash severance amounts and excise tax gross-ups do not reflect any amounts related to non-cash severance benefits, such as the value of continued health and welfare benefits or stock option acceleration, or any retention bonus or other applicable payment.

      Mr. Markison’s estimated severance payments are described above under “King Offer Letter — Brian Markison.” Mylan has proposed terms for an employment agreement with Mr. Lattanzi, which are described below under “Mylan Proposed Terms of Employment Agreement with James Lattanzi.” The proposed terms include severance benefits in lieu of the benefits under King’s existing severance policy. As a result, severance benefits provided to Mr. Lattanzi following the completion of the merger could be different from those set forth in the table above.

      Under King’s existing severance policy and certain agreements entered into with Mr. Jefferson Gregory, King’s former chief executive officer, and Mr. Kyle Macione, King’s former president, in the event Mr. Gregory or Mr. Macione is subject to an excise tax because any payments or benefits are deemed to be “excess parachute payments” within the meaning of Section 280G of the Code, then the former executive will be entitled to a tax gross-up payment that restores him to the same after-tax position that he would have been in had the excise tax not been imposed.

     Mylan Proposed Terms of Employment Agreement with James Lattanzi

      Mylan has proposed certain terms for an employment agreement that it may enter into with Mr. Lattanzi. Mylan’s proposal to Mr. Lattanzi is not binding, and Mr. Lattanzi has not accepted the proposal. Mr. Lattanzi is currently considering the proposal. The terms proposed by Mylan include a two-year employment agreement that would be effective as of the completion of the merger. Mr. Lattanzi’s title would be Executive Vice President — Finance of Branded Division and General Manager of Bristol Facilities, his annual salary would be $400,000 and he would be entitled to an annual bonus with a target opportunity of 60% of his salary. Mr. Lattanzi would also be entitled to a retention bonus of $500,000, one-third of which would be payable upon completion of the merger and one-third of which would be payable on each of the first two anniversaries of the completion of the merger. Mr. Lattanzi would receive

59

the same fringe benefits as those provided to other employees at his level, and he would receive stock options for 100,000 Mylan shares on the date of the completion of the merger, one-half of which would vest on each of the third and fourth anniversaries of the completion of the merger.

      Under Mylan’s proposed terms, upon termination “without cause,” or resignation for “good reason,” during the term of the employment agreement, Mr. Lattanzi would be entitled to a severance payment equal to two times the sum of his annual salary and target bonus, as well as a pro-rata bonus for his year of termination, any unpaid retention bonus, continued health coverage for two years and vesting of his outstanding stock options. Alternatively, if Mr. Lattanzi’s employment were terminated as a result of Mylan’s non-renewal of the term of the employment agreement, under Mylan’s proposal Mr. Lattanzi would receive a severance payment of $1,526,400 at the end of the term. Under the proposed terms, Mr. Lattanzi would be subject to non-competition and non-solicitation provisions for a period of two years.

      Under Mylan’s proposed terms, Mylan would also enter into a Transition and Succession Agreement with Mr. Lattanzi based on Mylan’s standard form of agreement, which would provide protections to Mr. Lattanzi in the event of a future change of control of Mylan.

     Retention Arrangements

      Pursuant to the merger agreement, King will develop a list of employees who will be entitled to receive up to an aggregate of $6,800,000 in retention arrangements in connection with the merger. Those employees are expected to receive a retention bonus if they remain employed through a certain period of time following the completion of the merger. If any of those employees are involuntarily terminated without cause prior to receiving the retention payment, it is expected that the employee will receive the retention bonus upon termination of employment, in addition to any severance otherwise payable to the employee pursuant to King’s existing severance policy or any individual agreement to which the employee is a party. It is expected that some or all of King’s executive officers, other than Messrs. Markison and Lattanzi, will be included in the list of employees eligible to receive a retention payment.

     Non-Employee Director Deferred Compensation Plan

      Upon the completion of the merger, directors who participate in King’s Non-Employee Director Deferred Compensation Plan will receive their account balances under the plan in a lump-sum cash payment. As of June 30, 2004, the account balances under the plan for King’s current directors were as set forth in the table below:

     Indemnification and Benefits Provisions in the Merger Agreement

      The merger agreement provides for director and officer indemnification and insurance, and for the provision of employee benefits, for specified time periods, and King’s charter requires indemnification of directors, officers and employees to the fullest extent available under Tennessee law. Those provisions are described in the sections entitled “The Merger Agreement — Indemnification and Insurance” and “The Merger Agreement — Employee Plans and Benefits” beginning on pages 81 and 80, respectively.

Form of Merger

      Subject to the terms and conditions of the merger agreement and in accordance with Tennessee law, at the completion of the merger, Summit Merger Corporation, a direct, wholly-owned subsidiary of Mylan formed for the purpose of the merger, will be merged with and into King. King will survive the merger as a direct, wholly-owned subsidiary of Mylan.

Effective Time of the Merger

      The merger will become effective upon the filing of the articles of merger with the Secretary of State of the State of Tennessee or at such later time as agreed upon by Mylan and King and as specified in the articles of merger. The filing of the articles of merger will occur as soon as practicable after satisfaction or waiver of the conditions to completion of the merger set forth in the merger agreement.

Board of Directors Following the Merger

      Upon completion of the merger, the Mylan board of directors will remain unchanged.

      The directors of Summit Merger Corporation will be the initial directors of the surviving corporation following the merger of Summit Merger Corporation with and into King.

Consideration to Be Received in the Merger

      For a description of the consideration to be received in the merger, see the section entitled “The Merger Agreement — Consideration to be Received in the Merger” beginning on page 67.

Procedures for Exchange of Certificates

      For a summary of the procedures for the exchange of King common stock certificates, see the sections entitled “The Merger Agreement — Exchange of Certificates in the Merger” on page 67, “— Treatment of Stock Options” on page 67 and “— Fractional Shares” beginning on page 68.

Listing of Mylan Common Stock

      It is a condition to the completion of the merger that the Mylan common stock issuable in the merger or upon exercise of options to purchase Mylan common stock issued in substitution for outstanding King options be authorized for listing on the NYSE, upon official notice of issuance.

Delisting and Deregistration of King Common Stock

      If the merger is completed, King common stock will be delisted from the NYSE and will be deregistered under the Exchange Act.

Regulatory Approvals Required for the Merger

      U.S. Antitrust Laws. Under the HSR Act and its associated rules, the merger may not be completed until notifications have been given and certain information and materials have been furnished to and reviewed by the Antitrust Division of the U.S. Department of Justice and the Federal Trade Commission and the required waiting period has expired or been terminated. Mylan and King filed the required notification and report forms under the HSR Act with the Federal Trade Commission and the Department of Justice on September 2, 2004. The waiting period will expire on October 4, 2004 (30 days after the forms were filed or on the next regular business day if the 30th day falls on a Saturday, Sunday or legal public holiday) unless early termination of the applicable waiting period is granted or a request for additional information is issued. If a request for additional information is issued, the parties would not be able to complete the merger until 30 days after both parties substantially comply with that request, or on the next regular business day if the 30th day falls on a Saturday, Sunday or legal public holiday.

61


Table of Contents

      At any time before or after the completion of the merger, the Antitrust Division of the Department of Justice or the Federal Trade Commission may, however, challenge the merger on antitrust grounds. Private parties could take action under the antitrust laws, including seeking an injunction prohibiting or delaying the merger, divestiture or damages under certain circumstances. Additionally, at any time before or after the completion of the merger, any state could take action under its antitrust laws as it deems necessary or desirable in the public interest. There can be no assurance that a challenge to the merger will not be made or that, if a challenge is made, Mylan and King will prevail.

      Other Approvals. The merger is not subject to any merger control filings under foreign antitrust laws.

Certain U.S. Federal Income Tax Consequences of the Merger

      The merger is intended to qualify as a “tax-free” reorganization for U.S. federal income tax purposes. See the section entitled “Certain U.S. Federal Income Tax Consequences of The Merger” beginning on page 65.

Accounting Treatment

      Mylan prepares its financial statements in accordance with applicable SEC rules and regulations and U.S. GAAP. The merger will be accounted for using the purchase method of accounting with Mylan being considered the acquirer of King for accounting purposes. This means that Mylan will allocate the purchase price to the fair value of assets acquired (including identifiable intangible assets) and liabilities assumed from King at the acquisition date, with the excess purchase price being recorded as goodwill. Under the purchase method of accounting, goodwill is not amortized but is tested for impairment at least annually.

Financing Structure

      King’s only outstanding capital markets debt is its $345 million aggregate principal amount of 2 3/4% Convertible Debentures due 2021, which are referred to as the 2 3/4% convertible debentures. The merger will constitute a change of control under the indenture governing the 2 3/4% convertible debentures. Accordingly, following the merger, each holder of the 2 3/4% convertible debentures will have the right, at such holder’s option, to have their 2 3/4% convertible debentures repurchased at the change of control purchase price, as defined in the indenture, which is equal to 100% of the principal amount of such convertible debentures plus accrued and unpaid interest.

Rights Agreement

      In connection with the initial public offering of King’s common stock, the King board of directors approved a rights agreement as attached to the Form 8-A filed with the SEC on June 9, 1998. On the date of the merger agreement, the King board of directors approved, and King entered into, a rights agreement that amends and restates the rights agreement approved in 1997. The terms and conditions of the rights agreement are substantially the same as the terms and conditions contained in the form of rights agreement approved in 1997, except that the rights agreement as amended and restated provides exemptions for the merger agreement and the transactions contemplated by the merger agreement.

Restrictions on Sales of Shares of Mylan Common Stock Received in the Merger

      Mylan common stock issued in the merger will not be subject to any restrictions on transfer arising under the Securities Act, except for shares issued to any King shareholder who may be deemed to be an “affiliate” of Mylan or King for purposes of Rule 145 under the Securities Act.

      Under Rule 145, former King shareholders who are affiliates of King at the time of the King special meeting, and who are not affiliates of Mylan after the completion of the merger, may sell their Mylan common stock at any time subject to the volume and sale limitations of Rule 144 under the Securities Act. Further, so long as such former King affiliates are not considered affiliates of Mylan following the completion of the merger, and a period of at least one year has elapsed from the completion of the merger,

62


Table of Contents

such former affiliates may sell their Mylan common stock without regard to the volume and sale limitations of Rule 144 under the Securities Act so long as there is adequate current public information available about Mylan in accordance with Rule 144. After a period of two years has elapsed from the completion of the merger, and so long as such former affiliates are not affiliates of Mylan and have not been for at least three months prior to such sale, such former affiliates may freely sell their Mylan common stock. Former King shareholders who become affiliates of Mylan after completion of the merger will still be subject to the volume and sale limitations of Rule 144 until each such shareholder is no longer an affiliate of Mylan. This joint proxy statement/prospectus does not cover resales of Mylan common stock received by any person upon completion of the merger, and no person is authorized to make any use of this joint proxy statement/prospectus in connection with any resale.

Charter and Bylaws of King

      Upon completion of the merger of Summit Merger Corporation, a direct, wholly-owned subsidiary of Mylan, with and into King, King’s articles of incorporation will be amended and restated to be identical to the articles of incorporation of Summit Merger Corporation except that the surviving corporation will remain named King Pharmaceuticals, Inc., and King’s bylaws will also be amended and restated to be identical to the bylaws of Summit Merger Corporation.

Dissenters’ Rights

      Under Tennessee law, King shareholders are not entitled to dissenters’ rights in connection with the merger if King common stock is listed on the NYSE at the time the merger is completed.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

      The following is a discussion of certain U.S. federal income tax consequences of the merger to King shareholders who exchange their shares of King common stock for shares of Mylan common stock in the merger. This discussion addresses only King shareholders who are U.S. Holders (as defined below) and hold King common stock as a capital asset. It does not address all of the U.S. federal income tax consequences that may be relevant to a particular King shareholder in light of that shareholder’s individual circumstances or to a King shareholder who is subject to special rules, including, without limitation:

  •  a financial institution or insurance company;
 
  •  a tax-exempt organization;
 
  •  a shareholder who is not a U.S. Holder;
 
  •  a pass-through entity or an investor in such an entity;
 
  •  a dealer or broker in securities or foreign currencies;
 
  •  a shareholder who holds King common stock as part of a hedge, appreciated financial position, straddle, constructive sale or conversion transaction; and
 
  •  a shareholder who acquired his or her shares of King common stock pursuant to the exercise of employee stock options or otherwise as compensation.

      The following discussion is based on the Code, applicable Treasury regulations, administrative interpretations and court decisions, each as in effect as of the date of this joint proxy statement/prospectus and all of which are subject to change, possibly with retroactive effect. This discussion is not binding on the Internal Revenue Service, which is referred to as the IRS, and there can be no assurance that the IRS (or a court, if challenged by the IRS) will agree with the conclusions stated herein. In addition, this discussion does not address any state, local or foreign tax consequences of the merger. King shareholders are urged to consult their tax advisors as to the specific tax consequences to them of the merger in light of their particular circumstances including the applicability and effect of U.S. federal, state, local, foreign and other tax laws.

      “U.S. Holder” refers to a beneficial owner of common stock that is (i) an individual citizen or resident of the United States, (ii) a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (iv) a trust (x) that is subject to the supervision of a court within the United States and the control of one or more U.S. persons as described in section 7701(a)(30) of the Code or (y) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

      If a partnership holds common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of that partnership. If a U.S. Holder is a partner of a partnership holding that common stock, the holder is urged to consult its tax advisor regarding the tax consequences of the merger.

      It is a condition to the completion of the merger that Mylan receive a written opinion from its counsel, Skadden, Arps and that King receive a written opinion from its counsel, Cravath, in each case dated as of the effective date of the merger, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither Mylan nor King intends to waive this closing condition. In the event that either Mylan or King waives receipt of such opinion from its counsel, however, Mylan and King will resolicit the approval of its shareholders after providing appropriate disclosure. The opinions will rely on certain assumptions as well as representations and covenants made by Mylan, Summit Merger Corporation and King. If any of those assumptions, representations or covenants are inaccurate, counsel may not be able to render the required opinions and the tax consequences of the merger could differ from those discussed here. An opinion of counsel is not binding on the IRS or any court, nor does it

64


Table of Contents

preclude the IRS from adopting a contrary position. No ruling has been or will be sought from the IRS on the U.S. federal income tax consequences of the merger.

      Assuming that the merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, for U.S. federal income tax purposes:

  •  holders of King common stock will not recognize gain or loss in connection with the conversion of their shares of King common stock into the right to receive shares of Mylan common stock and the receipt of shares of Mylan common stock in the merger, except to the extent of cash, if any, received in lieu of a fractional share of Mylan common stock;
 
  •  a King shareholder’s aggregate tax basis in shares of Mylan common stock received in the merger (including any fractional share interests deemed to be received and converted to cash) will equal the aggregate tax basis of the King common stock surrendered in the merger; and
 
  •  a King shareholder’s holding period for shares of Mylan common stock received in the merger will include the holding period for the shares of King common stock surrendered in the merger.

Cash in Lieu of Fractional Shares

      To the extent that a King shareholder receives cash in lieu of a fractional share of Mylan common stock, the shareholder will be deemed to have received that fractional share in the merger and then to have received the cash in exchange for that fractional share. The shareholder will generally recognize capital gain or loss equal to the difference between the cash received and the portion of the shareholder’s tax basis in the shares of King common stock surrendered allocable to that fractional share. This capital gain or loss will generally be long-term capital gain or loss if the King shareholder’s holding period for its shares of King common stock exceeded one year at the completion of the merger.

Backup Withholding and Information Reporting

      Non-corporate U.S. Holders of King common stock may be subject to information reporting and backup withholding on any cash payments received in lieu of a fractional share interest in Mylan. These U.S. Holders will not be subject to backup withholding, however, if they:

  •  furnish a correct taxpayer identification number and certify that they are not subject to backup withholding on the Form W-9 or successor form included in the letter of transmittal to be delivered to the holders following the completion of the merger; or
 
  •  are otherwise exempt from backup withholding.

      Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against that holder’s U.S. federal income tax liability, provided the required information or appropriate claim for refund is furnished to the IRS.

      U.S. Holders receiving Mylan common stock as a result of the merger generally will be required to retain records pertaining to the merger and generally will be required to file with their U.S. federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger.

THE MERGER AGREEMENT

      The following summarizes material provisions of the merger agreement which is attached as Annex A to this joint proxy statement/ prospectus and is incorporated by reference herein. The rights and obligations of the parties are governed by the express terms and conditions of the merger agreement and not by this summary or any other information contained in this joint proxy statement/ prospectus. Mylan and King shareholders are urged to read the merger agreement carefully and in its entirety as well as this joint proxy statement/ prospectus before making any decisions regarding the merger or the issuance of Mylan shares pursuant to the merger agreement.

General

      Under the merger agreement, Summit Merger Corporation, a direct, wholly-owned subsidiary of Mylan, will merge with and into King, with King continuing as the surviving corporation. As a result of the merger, King will become a direct, wholly-owned subsidiary of Mylan.

Closing Matters

      Closing. Unless the parties agree otherwise, the closing of the merger will take place on a date specified by the parties, but no later than the second business day after all closing conditions have been satisfied or waived, unless the parties agree to another date. See “— Conditions to Completion of the Merger” below for a more complete description of the conditions that must be satisfied or waived prior to closing.

      Completion of the Merger. The merger will become effective when Mylan, through Summit Merger Corporation, and King file articles of merger with the Secretary of State of the State of Tennessee in accordance with the relevant provisions of Tennessee law, or at such later time as Mylan and King agree and specify in the articles of merger.

Consideration to be Received in the Merger

      The merger agreement provides that, upon the completion of the merger, each share of King common stock issued and outstanding immediately prior to the completion of the merger, but excluding shares of King common stock held by King or Mylan, will be converted into the right to receive 0.9 shares of Mylan common stock, adjusted for stock splits, reverse stock splits, stock dividends, recapitalization or any other similar change to Mylan’s or King’s common stock whose record date occurs between the date of the merger agreement and the completion of the merger.

Treatment of Stock Options

      Upon completion of the merger, each option to purchase King common stock under a King stock option plan outstanding immediately prior to the completion of the merger will be assumed by Mylan and become an option to purchase, generally on the same terms and conditions as were applicable under such King stock option, shares of Mylan common stock. The number of shares of Mylan common stock underlying the new option will equal the number of shares of King common stock subject to the corresponding King option immediately prior to the completion of the merger, multiplied by 0.9 (rounded down to the nearest whole share). The per share exercise price of each new option will equal the per share exercise price of the corresponding King option divided by 0.9 (rounded up to the nearest cent).

Exchange of Certificates in the Merger

      At or prior to the completion of the merger, Mylan will engage an exchange agent to handle the exchange of King stock certificates for certificates representing shares of Mylan common stock and the payment of cash for fractional shares. Promptly after the completion of the merger, the exchange agent will send a letter of transmittal and instructions to each former King shareholder explaining the procedure

66


Table of Contents

for surrendering King stock certificates in exchange for certificates representing the number of shares of Mylan common stock into which the shares of King common stock will be converted in the merger.

      After the completion of the merger, each certificate that previously represented shares of King common stock will only represent the right to receive a certificate representing the shares of Mylan common stock into which the shares of King common stock have been converted and any cash payment in lieu of a fractional share. In addition, after the completion of the merger, King will not register any transfers of the shares of King common stock. Mylan shareholders need not exchange their stock certificates.

Fractional Shares

      No fraction of a share of Mylan common stock will be issued in the merger. Instead, the exchange agent will pay each of those shareholders who would otherwise be entitled to a fraction of a share of Mylan common stock an amount of cash (rounded to the nearest whole cent) determined by multiplying the fractional share interest (after aggregating all shares of Mylan common stock that would otherwise be received by such holder) which such holder would otherwise receive by the closing price of one share of Mylan common stock on the NYSE Composite Transactions Reporting System for the ten most recent trading days ending on the trading day one day prior to the completion of the merger.

Listing of Common Stock of the Combined Company

      It is a condition to the completion of the merger that the Mylan common stock issuable in the merger or upon exercise of options to purchase Mylan common stock issued in substitution for outstanding King stock options be authorized for listing on the NYSE, upon official notice of issuance.

Conditions to Completion of the Merger

      The obligations of King and Mylan to complete the merger are subject to the satisfaction or, if applicable, waiver of the following conditions:

  •  the approval and adoption of the merger agreement and the approval of the merger by King shareholders;
 
  •  the approval of the issuance of Mylan common stock pursuant to the merger by Mylan shareholders;
 
  •  the expiration or earlier termination of the applicable waiting periods under the HSR Act and any applicable foreign antitrust laws other than any waiting periods the failure of which to terminate or expire are not reasonably likely to have a material adverse effect on Mylan (after giving effect to the merger) or King other than any waiting period the failure of which to terminate or expire is not reasonably likely to have a material adverse effect on Mylan or King;
 
  •  the completion of all filings with governmental entities, and the receipt of all governmental and regulatory consents, approvals and authorizations, in each case that are necessary for the merger, unless failure to make or obtain them would not, individually or in the aggregate, have a material adverse effect on Mylan (after giving effect to the merger);
 
  •  the absence of any judgment, order, decree, statute, law, ordinance, rule or regulation or other legal constraint prohibiting or enjoining completion of the merger;
 
  •  the SEC having declared effective the registration statement of which this joint proxy statement/ prospectus forms a part and no stop order or proceeding seeking a stop order having been initiated or, to the knowledge of Mylan or King, having been threatened by the SEC;
 
  •  the authorization for listing on the NYSE of the Mylan common stock issuable to King shareholders in the merger and issuable pursuant to King’s stock option plans, upon official notice of issuance;

67


Table of Contents

  •  the receipt on the closing date of the merger by each of Mylan and King of an opinion, each from its respective counsel, to the effect that the merger will qualify as a “tax-free” reorganization under Section 368(a) of the Code;
 
  •  the respective representations and warranties of Mylan and King in the merger agreement being true and correct, unless the failure of the representations and warranties to be true and correct does not have and is not, individually or in the aggregate, reasonably likely to have a material adverse effect on the party making such representations and warranties;
 
  •  each of Mylan, Summit Merger Corporation and King having performed or complied with, in all material respects, its obligations under the merger agreement;
 
  •  no material adverse change, as defined in the merger agreement, affecting the other party having occurred or being reasonably likely to occur;
 
  •  the receipt of an officers’ certificate executed by the other party’s Chief Executive Officer and Chief Financial Officer stating that the conditions relating to the truth of representations and warranties and compliance with covenants have been satisfied; and
 
  •  the absence of any litigation seeking to prohibit or impose any material limitations on Mylan’s ownership of King or the operation of all or a material portion of Mylan’s or King’s respective businesses or assets or to compel Mylan or King to dispose of or hold separate any material portion of the business or assets of Mylan or King that is reasonably likely to have a material adverse effect on Mylan after giving effect to the merger or, in the case of Mylan’s closing condition only, a material adverse effect on King.

      In addition, Mylan’s obligation to complete the merger is subject to the following conditions:

  •  the absence of criminal charges against King or certain of its current or former directors and officers in connection with any issues that are being investigated by the SEC, the Office of Inspector General at the Department of Health & Human Services, the U.S. Attorney’s Office and other governmental entities, and the state and local equivalents thereof;
 
  •  Mylan generally having received no indication that any governmental entity has placed or is reasonably likely to place any prohibitions on King’s sales to Medicaid or any related federal or state program; and
 
  •  no restatement of any of King’s financial statements having occurred or being reasonably likely to occur.

Conduct of Business

      Each of Mylan and King have undertaken certain covenants in the merger agreement restricting the conduct of their respective businesses between the date the merger agreement was signed and the completion of the merger. You are urged to read carefully the section of the merger agreement entitled “Covenants Relating to Conduct of Business.” The following summarizes the more significant of these covenants.

 Covenants of Mylan and King

      Prior to the completion of the merger, except as expressly required by, or provided for, in the merger agreement, or consented to in advance by the other party in writing (which consents may not be unreasonably withheld or delayed), each of Mylan and King has agreed, subject to certain exceptions, to and to cause each of its subsidiaries to:

  •  use its reasonable best efforts to maintain its existence in good standing under applicable laws; and
 
  •  subject to certain restrictions and exceptions set forth in the merger agreement, conduct its operations only in the ordinary and usual course of business consistent with past practice.

68


Table of Contents

      In addition, prior to the completion of the merger, except as expressly required by, or provided for, in the merger agreement, or consented to in advance by Mylan in writing (which consent may not be unreasonably withheld or delayed), King has agreed to use its reasonable best efforts to and to cause each of its subsidiaries to:

  •  keep available the services of the current officers, employees and consultants;
 
  •  maintain and enforce all intellectual property;
 
  •  maintain its rights and franchises and preserve its current relationships with its customers, suppliers and others having business dealings with it;

Negative Covenants of Mylan, Summit Merger Corporation and King

      Between the date of the merger agreement and the effective date of the merger, each of Mylan, Summit Merger Corporation and King has agreed, subject to certain exceptions, not to take or permit any of their respective subsidiaries voluntarily to take any action that is reasonably likely to result in:

  •  any of the representations and warranties set forth in the merger agreement that are qualified as to “materiality” or “material adverse effect,” as the case may be, becoming untrue as of the closing;
 
  •  any of the representations and warranties that are not so qualified becoming untrue in any material respect as of the closing; or
 
  •  any of the conditions to the merger not being satisfied.
 
Negative Covenants of Mylan

  •  amend or otherwise change its articles or certificates of incorporation or bylaws or equivalent organizational documents in a manner that would adversely affect the holders of Mylan common stock, except to increase the authorized number of shares of Mylan capital stock;
 
  •  issue any shares of Mylan common stock if, following such issuance, an insufficient number of shares would be available to pay the merger consideration and to be reserved for issuance in connection with the transactions contemplated by the merger agreement;

  •  repurchase, redeem or acquire, or permit its subsidiaries to purchase or acquire any shares of its capital stock or any securities convertible into or exchangeable for any shares of its capital stock;
 
  •  take any action which would or could reasonably be expected to cause the merger not to constitute a “tax-free” reorganization; or
 
  •  authorize or enter into any agreement or otherwise make any commitment to do any of the foregoing.

Negative Covenants of King

      In addition, between the date of the merger agreement and the completion of the merger, subject to certain exceptions, King has agreed that, without the prior written consent of Mylan (such consent not to be unreasonably withheld or delayed), it will not and will not permit any of its subsidiaries to:

  •  amend or otherwise change its charter, articles or certificate of incorporation or bylaws or equivalent organizational documents;

No Solicitation

      King has agreed that, subject to certain exceptions, King and its subsidiaries will not, and King will not authorize or permit any of its officers, directors, employees, investment bankers, financial advisors, attorneys, accountants or other representatives to, take any of the following actions:

  •  solicit, initiate, encourage (including by furnishing any information) or take any other action to, or which is designed or intended to, facilitate, induce or encourage any inquiries with respect to, or the making, submission or announcement of, any “alternative transaction” proposal (as defined below);
 
  •  participate in any discussions or negotiations regarding, furnish any information with respect to, otherwise cooperate in any way with or knowingly facilitate any effort or attempt to make or implement any alternative transaction proposal;
 
  •  approve, endorse or recommend any alternative transaction (except to the extent specifically permitted in the merger agreement, as described below); or
 
  •  enter into any letter of intent, agreement or commitment (whether binding or not) contemplating or otherwise relating to any possible or proposed alternative transaction proposal.

      King also agreed that, upon signing the merger agreement, King and its subsidiaries would immediately cease, and would cause their respective officers, directors, employees, investment bankers, financial advisors, attorneys, accountants and other representatives to cease, any and all existing activities, discussions or negotiations with any third parties with respect to any possible or proposed alternative transaction.

      The merger agreement also provides that King will, as promptly as reasonably practicable (and in any event within 48 hours) after receipt of any alternative transaction proposal or any request for nonpublic information or any inquiry relating to any alternative transaction proposal, provide Mylan with oral and written notice of the material terms and conditions of such alternative transaction proposal, request or inquiry and the identity of the person making such request or inquiry. In addition, King will keep Mylan informed in all material respects of the status and details (including amendments or proposed amendments) of any such alternative transaction proposal, request or inquiry, and King and Mylan will cause their respective outside legal counsel to establish a regular schedule (as reasonably agreed by Mylan and King) for telephonic conversations between their respective outside legal counsel for the purpose of providing updates of such status and details. In addition, King must cause its outside legal counsel to endeavor to provide reasonable advance notice to Mylan’s outside legal counsel of any meeting of King’s board of directors at which it is reasonably likely that King’s board of directors will consider or otherwise discuss any alternative transaction proposal or alternative transaction.

      An “alternative transaction” includes any liquidation or dissolution of such party or any transaction or series of related transactions with one or more third persons involving any one or more of the following:

  •  any purchase from such party or acquisition (whether by way of a merger, share exchange, consolidation, business combination, consolidation or similar transaction) by any person or “group” of persons (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a 25% interest in the total outstanding voting securities of such party;

72


Table of Contents

  •  any tender offer or exchange offer that, if consummated, would result in any person or group of persons beneficially owning 25% or more of the total outstanding voting securities of such party;
 
  •  any merger, consolidation, business combination or similar transaction involving such party; or
 
  •  any sale, lease, exchange, transfer, license, acquisition or disposition of more than 25% of the aggregate fair market value of the consolidated assets of King and its subsidiaries, taken as a whole, immediately prior to such sale, lease, exchange, transfer, license, acquisition or disposition.

      King, in response to an unsolicited, bona fide written alternative transaction proposal at any time prior to obtaining the King shareholder approval that is determined in good faith by King’s board of directors (after receipt of advice from its outside legal and financial advisors) to be, or is reasonably likely to lead to, a “superior proposal” (as defined below), may, if King has given Mylan at least 24-hour prior written notice of its intention to take any of the following actions and of the identity of the person or the group of persons making such alternative transaction proposal and the terms and conditions of such alternative transaction proposal and if King has not breached any of the applicable provisions of the no-solicitation section of the merger agreement:

  •  furnish information (including nonpublic information) to the person making such alternative transaction proposal, provided that, prior to furnishing such nonpublic information, it receives from such person an executed confidentiality agreement containing terms at least as restrictive as the terms of the Confidentiality Agreement between Mylan and King and, contemporaneously with furnishing any such nonpublic information to such person, it furnishes such nonpublic information to Mylan and
 
  •  engage in discussions or negotiations with such person with respect to such alternative transaction proposal.

      A “superior proposal” means an unsolicited, bona fide alternative transaction proposal by a third party to acquire:

  •  all or substantially all of King’s assets, or
 
  •  all of the outstanding voting securities of King and, as a result of which, the shareholders of King would hold less than 55% of the equity interests in the surviving entity.

      In addition, for a proposal to qualify as a “superior proposal,” King’s board of directors must determine in good faith that the third party proposal is more favorable from a financial point of view to King’s shareholders than the merger agreement with Mylan (as it may be proposed to be amended by Mylan), and such proposal is reasonably capable of being consummated on the terms proposed, after taking into account:

  •  the advice of its outside legal and financial advisors,
 
  •  all terms and conditions of such proposal and all amendments to the merger agreement proposed by Mylan, and
 
  •  other aspects of such proposal and the person making such proposal.

      Further, if a proposal qualified as a superior proposal the merger agreement may be terminated by Mylan or King, and King may enter into a transaction with the person making the superior proposal under the circumstances described under the section entitled “The Merger Agreement — Termination of the Merger Agreement” beginning on page 78.

Changes of Recommendation

      Either party’s board of directors may withhold, withdraw, amend or modify its recommendation to its shareholders if the party considering changing its recommendation has complied in all material respects with the procedures set forth in the merger agreement and described below and such board reasonably determines in good faith, after consultation with outside legal and financial advisors, that a material

73


Table of Contents

adverse effect on the other party has occurred and that such action is consistent with their fiduciary duties. In addition, before any change of recommendation, the parties must comply with a process whereby:

  •  the party considering changing its recommendation provides advance notice of meetings of the board of directors at which such party’s board of directors is reasonably likely to consider whether there has been a material adverse effect on the other party or whether to change its recommendation;
 
  •  counsel to the parties will be in regular contact regarding the material respects of the status and details of the board’s consideration of whether there has been a material adverse effect on the other party or whether to change its recommendation; and
 
  •  the party considering changing its recommendation must provide the other party advance notice (no less than four business days) of any meeting at which a board of directors determines that a material adverse effect on the other party has occurred or to change its recommendation, and the other party will be entitled to submit information to the executive officers of the party considering changing its recommendation and meet with its executive officers and advisors to engage in good faith discussions regarding the consideration by the board of such determination, except that the party considering changing its recommendation shall not be required to disclose any information that would result in the loss of the attorney client privilege.

Other Covenants and Agreements

      SEC and OIG Investigations. King has agreed that Mylan has the right to consent (which consent may not be unreasonably withheld or delayed) to any settlement between King and the SEC, the OIG, the U.S. Attorney’s Office or the other governmental entities, or the state and local equivalents thereof, investigating the calculation, payment and reporting of Medicaid rebates and sales and marketing of products of King, which are referred to as the SEC and OIG investigations, or the related shareholder litigation. Subject to certain limitations and exceptions, King also has agreed to use its reasonable best efforts to provide Mylan with advance notice of intended communications regarding the SEC and OIG investigations and to allow a representative of Mylan to monitor or participate in the intended communications.

      Expenses. Each party has agreed to pay its own fees and expenses incurred in connection with the merger and the merger agreement, except that each party has agreed to pay 50% of any expenses (other than attorneys’ fees, accountants’ fees and related expenses) incurred in connection with the filing, printing and mailing of the registration statement (including financial statements and exhibits) of which this joint proxy statement/ prospectus forms a part (including SEC filing fees) and any preliminary materials relating to it and the filing of premerger notification and report forms under the HSR Act and any other applicable antitrust, competition or similar laws (including filing fees).

      Other Covenants and Agreements. The merger agreement contains other covenants and agreements, including covenants and agreements relating to:

      Mylan’s opportunity to participate, to the extent reasonably possible, in the defense or settlement of any shareholder action against King or King’s directors in connection with the merger or other transaction contemplated thereby (including an agreement that no settlement will be agreed to without Mylan’s prior written consent, not to be unreasonably withheld).

Table of Contents

  •  absence of any circumstance that impairs in any material respect the ability of Mylan to perform its obligations under the merger agreement or is reasonably likely to prevent or materially delay completion of the merger.

      Many of the representations of King and Mylan are qualified by a knowledge, materiality or “material adverse effect” exception.

      “Material adverse effect” is defined to mean any change, event, violation, circumstance or effect that, individually or in the aggregate, is materially adverse to the business, assets, liabilities, financial condition or results of operations of a party and its subsidiaries, taken as a whole. Certain events, changes or circumstances will be excluded from the determination of a material adverse effect, including those that arise out of or result from: (i) events or circumstances adversely and generally affecting the industry in which such party operates, and which do not have a materially disproportionate effect on such party; (ii) general economic conditions; (iii) the announcement or performance of the merger agreement; and (iv) any effects to the extent resulting from the matters set forth in (i)-(iii).

      The material adverse effect definition that applies to King also provides that, notwithstanding matters known to Mylan or its representatives on the date of the merger agreement or otherwise, all losses incurred or reasonably expected to be incurred in connection with any effect arising out of the SEC and the OIG investigations of King, or the related shareholder litigation, will be considered in the determination of a material adverse effect on King. Mylan acknowledged that, based on its knowledge as of the date of the merger agreement, if the closing of the merger were to occur on the date of the merger agreement, Mylan would not have the right to assert that a material adverse effect on King, solely as it relates to such investigations and related actions, had occurred.

Termination of the Merger Agreement

      Right to Terminate. The merger agreement may be terminated at any time prior to the completion of the merger under the following circumstances, subject to certain exceptions:

  •  by mutual written consent of Mylan and King, if the board of directors of each so determines;
 
  •  by written notice of Mylan or King to the other party for any of the following reasons:

        (1) if the merger has not been consummated by February 28, 2005;
 
        (2) if a governmental entity has issued a final and nonappealable order, decree or ruling or taken any other action or inaction having the effect of permanently restraining, enjoining or otherwise prohibiting the merger;
 
        (3) if the shareholders of King have not approved and adopted the merger agreement and approved the merger at the King special meeting, or at any adjournment or postponement thereof, provided that King may not terminate the merger agreement under this provision if the failure to obtain King shareholder approval was caused by a material breach of the merger agreement by King;
 
        (4) if the shareholders of Mylan have not approved the issuance of shares of Mylan common stock to King shareholders pursuant to the merger at the Mylan special meeting, or at any adjournment or postponement thereof, provided that Mylan may not terminate the merger agreement under this provision if the failure to obtain Mylan shareholder approval was caused by a material breach of the merger agreement by Mylan;
 
        (5) if, at any time prior to Mylan shareholder approval, there was a material adverse effect on King, and Mylan’s board of directors changed its recommendation to shareholders; or
 
        (6) if, at any time prior to King shareholder approval, there was a material adverse effect on Mylan, and King’s board of directors changed its recommendation to shareholders;

77


Table of Contents

  •  by Mylan or King if there has been a breach by the other party of the representations and warranties or covenants that would result in a failure to satisfy the related closing condition (subject generally to an opportunity to cure the breach);
 
  •  by Mylan, at any time prior to the approval and adoption of the merger agreement and approval of the merger by King shareholders, if the King board of directors determines that an alternative transaction proposal constitutes a superior proposal, and King provides notice to Mylan that King intends to enter into a binding agreement with respect to such superior proposal; or
 
  •  by King, at any time prior to the approval and adoption of the merger agreement and approval of the merger by King shareholders, if:

        (1) the King board of directors authorizes King, subject to complying with the terms of the merger agreement, to enter into a binding written agreement relating to a transaction constituting a superior proposal and King notifies Mylan in writing of its intention to enter into such an agreement, providing a copy of the agreement or description of the material terms and conditions thereof;
 
        (2) Mylan does not make, within four business days of receipt of King’s written notice of its intention to enter into a binding agreement for a superior proposal, an offer that the King board of directors determines, in good faith after consultation with a financial advisor of nationally recognized reputation, is at least as favorable to King shareholders as the superior proposal; and
 
        (3) King, at or prior to any termination, pays Mylan a termination fee equal to $85 million.

Termination Fee

      King will be obligated to pay a termination fee of $85 million if the merger agreement is terminated:

  •  by Mylan or King because the shareholders of King have not approved and adopted the merger agreement and approved the merger at the King special meeting, or at any adjournment or postponement thereof, but only if between the date of the merger agreement and the date of such termination, any person has made to King or its shareholders, or publicly announced, a proposal, offer or indication of interest relating to any acquisition with respect to King and within twelve months following termination of the merger agreement, an acquisition of King is consummated or King enters into an agreement providing for an acquisition of King;
 
  •  by Mylan, at any time prior to the approval and adoption of the merger agreement and approval of the merger by King shareholders, if the King board of directors determines that an alternative transaction proposal constitutes a superior proposal, and King provides notice to Mylan that King intends to enter into a binding agreement with respect to such superior proposal; or
 
  •  by King, at any time prior to the approval and adoption of the merger agreement and approval of the merger by King shareholders, if:

        (1) the King board of directors authorizes King, subject to complying with the terms of the merger agreement, to enter into a binding written agreement relating to a transaction constituting a superior proposal and King notifies Mylan in writing of its intention to enter into such an agreement, providing a copy of the agreement or description of the material terms and conditions thereof; and
 
        (2) Mylan does not make within four business days of receipt of King’s written notice of its intention to enter into a binding agreement for a superior proposal an offer that the King board of directors determines, in good faith after consultation with a financial advisor of nationally recognized reputation, is at least as favorable to King shareholders as the superior proposal.

78


Table of Contents

      Mylan will be obligated to pay a termination fee of $85 million if the merger agreement is terminated:

  •  by Mylan, because Mylan failed to obtain the approval by the Mylan shareholders of the issuance of shares of Mylan common stock pursuant to the merger by Mylan shareholders, provided that such termination fee is payable by Mylan only if between the date of the merger agreement and the termination, any person has made to Mylan or its shareholders, or publicly announced, a proposal, offer or indication of interest relating to any acquisition with respect to Mylan and within twelve months following termination of the merger agreement, an acquisition of Mylan is consummated or Mylan enters into an agreement providing for an acquisition of Mylan.

      An “acquisition” of Mylan or King means, with certain exceptions, any of the following:

  •  a merger, consolidation, business combination, recapitalization, liquidation, dissolution or other similar transaction involving such party pursuant to which the party’s shareholders hold less than 45% of the aggregate equity interests in the entity surviving the transaction or its parent;
 
  •  a sale or disposition by such party of assets representing more than 45% of the aggregate fair market value of its consolidated assets; or
 
  •  a direct or indirect acquisition by any person or group of persons of beneficial ownership or a right to acquire beneficial ownership of shares representing more than 45% of the voting power of such person’s then outstanding capital stock.

Employee Plans and Benefits

      Mylan and King have agreed in the merger agreement that, immediately following the completion of the merger and until December 31, 2005, Mylan will provide or will cause to be provided to employees of King and its subsidiaries who continue to be employed by Mylan, King or any of their subsidiaries following the completion of the merger:

  •  compensation and benefits that in the aggregate are no less favorable than those provided by King and its subsidiaries immediately prior to the completion of the merger; and
 
  •  eligibility for periodic increases in compensation and/or promotions generally consistent with the then current policies of Mylan and its subsidiaries for employees of Mylan and its subsidiaries who are employed in comparable positions.

      Each continuing King employee who is terminated within two years following the completion of the merger will receive severance benefits (based on the change of control that will occur at the completion of the merger under the terms of King’s existing severance policy) that are no less favorable than those provided under King’s existing severance policy. Notwithstanding anything to the contrary in King’s existing severance policy, equity awards granted to King employees following the completion of the merger will be governed by the terms and conditions of the award agreements issued under the applicable Mylan equity plans.

      For two years following the completion of the merger, continuing King employees will be eligible to participate in all stock option, bonus, profit-sharing and similar plans of Mylan and its subsidiaries to the same extent as employees of Mylan and its subsidiaries who are employed in comparable positions. Furthermore, following the completion of the merger, each continuing King employee will be eligible to participate in Mylan’s vacation policies and will receive at least as many vacation days per year as he or she was entitled to receive as of the completion of the merger under King’s plans and agreements.

      Mylan has agreed to honor King’s benefit plans and agreements. Subject to compliance with its obligations under the merger agreement, Mylan may amend or terminate King’s benefit plans and agreements in accordance with their terms as in effect immediately prior to the completion of the merger.

      With respect to benefit plans maintained by Mylan or any of its subsidiaries in which continuing King employees are eligible to participate following the completion of the merger, service with King and its subsidiaries (and their respective predecessor employers, to the extent King and its subsidiaries recognize

79


Table of Contents

such service) will be treated as service with Mylan and its subsidiaries for purposes of determining vesting and entitlement to benefits, except that such service will not be recognized for purposes of defined benefit pension accruals or to the extent that it would result in any duplication of benefits or was not recognized under the applicable King plan or agreement.

Indemnification and Insurance

      In the merger agreement, Mylan has agreed that, upon completion of the merger, it will cause the surviving corporation in the merger to indemnify, defend and hold harmless each present and former director or officer of King or any of its subsidiaries against any costs and expenses, judgments, losses, claims, damages, liabilities and, subject to the provisions of the merger agreement, amounts paid in settlement in connection with or arising out of that person’s service as a director or officer of King or any of its subsidiaries, or arising out of the merger or the merger agreement, in each case to the fullest extent permitted by law. Mylan will also be required to cause the surviving corporation to pay to those persons expenses reasonably incurred in connection with the defense of any indemnified claims, and to pay the expenses incurred by them while acting as a witness in any indemnified claim.

      In addition, the merger agreement provides that Mylan will honor all existing rights to indemnification in favor of officers or directors of King. Under the Tennessee Business Corporation Act, in a proceeding to which the director or officer was a party because he or she is or was a director or officer a corporation must indemnify its directors and officers against reasonable expenses incurred by the director or officer to the extent the director or officer was wholly successful on the merits or otherwise in the defense of the proceeding. King’s charter provides that each director, officer and employee of King shall be entitled to all indemnification rights and protections available under applicable Tennessee law.

      In addition, Mylan will be required to maintain the directors’ and officers’ insurance policies of King (or policies providing comparable coverage containing terms that are no less advantageous) for a period of six years after the merger, although Mylan would not be required to pay annual premiums that exceed 300% of the current annual premiums paid by King (in which case Mylan would be required to obtain as much insurance as possible at a cost equal to 300% of the current annual premiums).

Amendments, Extensions and Waivers

      Amendment. The merger agreement may be amended by the parties at any time before or after the King shareholders adopt and approve the merger agreement and approve the merger or the Mylan shareholders approve the issuance of shares of Mylan common stock to King shareholders pursuant to the merger. However, after King’s shareholder approval, there may not be, without further approval of King shareholders, any amendment of the merger agreement that changes the amount or the form of the consideration to be delivered to King shareholders, or any amendment for which applicable laws expressly require further shareholder approval.

      Extension; Waiver. At any time prior to the completion of the merger, with certain exceptions, any party may:

  •  extend the time for performance of any obligations or other acts of the other party;
 
  •  waive any inaccuracies in the representations and warranties of the other party contained in the merger agreement or in any document delivered pursuant to the merger agreement; or
 
  •  waive compliance by another party with any of the agreements or conditions contained in the merger agreement.

      The unaudited condensed combined pro forma statement of earnings for the twelve months ended March 31, 2004, combines information from the audited historical consolidated statement of earnings of Mylan for the fiscal year ended March 31, 2004, with the unaudited condensed statement of earnings of King for the twelve months ended March 31, 2004. The unaudited condensed statement of earnings of King for the twelve months ended March 31, 2004 has been prepared by adding the unaudited three-month period then ended to the audited statement of earnings for the year ended December 31, 2003, and subtracting the results for the unaudited three-month period ended March 31, 2003. The unaudited condensed combined pro forma statement of earnings for the three months ended June 30, 2004, combines information from the unaudited historical condensed consolidated statement of earnings of Mylan for the three months ended June 30, 2004, with the unaudited historical condensed consolidated statement of earnings of King for the three months ended June 30, 2004. The unaudited condensed combined pro forma balance sheet combines information from the unaudited historical condensed consolidated balance sheet of Mylan as of June 30, 2004, with the unaudited historical condensed consolidated balance sheet of King as of June 30, 2004, and assumes that the transaction closed on that date.

      The unaudited condensed combined pro forma financial statements were prepared using the purchase method of accounting. The allocation of the purchase price as reflected in these pro forma condensed combined financial statements has been based upon preliminary estimates of the fair values of assets acquired and liabilities assumed as of the date of the acquisition. Management is currently assessing the fair values of the tangible and intangible assets acquired and liabilities assumed. This preliminary allocation of the purchase price is dependent upon certain estimates and assumptions, which are preliminary and have been made solely for the purpose of developing such pro forma condensed combined financial statements.

      A final determination of the fair values of King’s assets and liabilities, which cannot be made prior to the completion of the transaction, will be based on the actual net tangible and intangible assets of King that exist as of the date of completion of the acquisition and such valuations could change significantly upon the completion of further analyses and asset valuations from those used in the condensed combined pro forma financial statements presented below.

      The unaudited condensed combined pro forma financial statements were prepared using the assumptions described below and in the related notes. The historical consolidated financial information has been adjusted to give effect to pro forma events that are:

  •  directly attributable to the acquisition;
 
  •  factually supportable; and

81


Table of Contents

  •  with respect to the statements of earnings, expected to have a continuing impact on the combined results.

      The unaudited condensed combined pro forma financial statements do not include liabilities resulting from integration planning and adjustments in respect of possible settlements of outstanding litigation (other than those already included in the historical financial statements of either company), as these are not presently estimable, nor do they include certain cost savings or operating synergies that may result from the acquisition, as such amounts are not currently determinable. Amounts preliminarily allocated to goodwill may significantly decrease and amounts allocated to intangible assets with definite lives may increase significantly, which could result in a material increase in amortization of acquired intangible assets. Therefore, the actual amounts recorded as of the completion of the transaction may differ materially from the information presented in the accompanying unaudited condensed combined pro forma financial statements. In addition to the completion of the final valuation of acquired assets and liabilities, the impact of ongoing integration activities, the timing of completion of the transaction and other changes in King’s net tangible and intangible assets that occur prior to completion of the transaction could cause material differences in the information presented.

      The unaudited condensed combined pro forma financial statements are provided for illustrative purposes only. They do not purport to represent what Mylan’s results of operations and financial position would have been had the transaction actually occurred as of the dates indicated, and they do not purport to project Mylan’s future results of operations or financial position.

PRO FORMA FINANCIAL STATEMENTS

Purchase Price

      These unaudited condensed combined pro forma financial statements reflect a preliminary allocation of the purchase price as if the transaction had been completed on April 1, 2003 with respect to the statements of earnings, and June 30, 2004, with respect to the balance sheet. The preliminary allocations are subject to change based on finalization of the fair values of the tangible and intangible assets acquired and liabilities assumed. The estimated purchase price of $3.7 billion has been calculated and preliminarily assigned to the net tangible and intangible assets acquired as follows:

      Purchase price calculation:

                 
Number of shares of King common stock outstanding at date of announcement of signing the agreement and plan of merger (in thousands)
    241,439          
Exchange ratio
    0.9          
     
         
      217,295          
Multiplied by Mylan’s average stock price for the period two business days before and two business days after the July 26, 2004 announcement of the acquisition
  $ 16.90     $ 3,672,287  
Estimated fair value of King stock options outstanding as of date of announcement of signing the agreement and plan of merger expected to be exchanged for Mylan stock options(1)
            31,978  
Other, including estimated transaction costs
            25,032  
             
 
Estimated purchase price
          $ 3,729,297  
             
 

      The preliminary allocation of the purchase price based on the estimated fair values of King’s assets and liabilities assumed in the acquisition are as follows (in thousands):

         
Purchase price allocation to net tangible and intangible assets acquired and to goodwill:
       
Net tangible assets at fair value
  $ 29,683  
Identifiable intangible assets
    2,214,500  
Excess of purchase price over the fair values of net assets acquired(2)
    1,234,114  
In-process research and development(3)
    251,000  
     
 
Total purchase price
  $ 3,729,297  
     
 


(1)  The fair value of King’s stock options was determined using the Black-Scholes option pricing model with the following assumptions: stock price of $16.90; dividend yield of 0.53%; expected volatility of 42%; risk-free interest rate of 3.0%; and an expected life of 6.5 years at date of grant.
 
(2)  The excess of the purchase price over the estimated fair value of identifiable net assets acquired has been classified as goodwill.
 
(3)  The amount allocated to in-process research and development represents an estimate of the fair value of purchased in-process research projects that, as of the closing date of the acquisition, will not have reached technological feasibility and have no alternative future use. The preliminary estimate of in-process research and development is $251.0 million. Because this expense is directly attributable to the acquisition and will not have a continuing impact, it is not reflected in the unaudited condensed combined pro forma statements of earnings. However, this item will be recorded as a charge against income in the period in which the transaction occurs. The amount of in-process research and development is subject to change and will be finalized upon consummation of the transaction and

86


Table of Contents

completion of a valuation. For every incremental $25 million increase to the amount allocated to in-process research and development expense, there will be a $25 million decrease to net income in the period in which the transaction occurs. Additionally, goodwill and retained earnings will also each decrease by $25 million.

Pro Forma Statements of Earnings Adjustments

      (a) Represents a reclassification to record shipping and handling costs in cost of sales in order to conform the presentation to that of Mylan.

      (b) Represents an adjustment to record the amortization expense of the amortizable intangible assets acquired as part of the acquisition assuming a useful life of 3 to 10 years. The amount of intangible assets, estimated useful lives and amortization methodology are subject to the completion of an appraisal. Assuming a useful life of 10 years, straight line amortization and a tax rate of 36%, for every additional $50 million allocated to intangible assets, net income will decrease by $3.2 million and $0.8 million in the year ended March 31, 2004 and the three months ended June 30, 2004, respectively.

      (c) Represents an adjustment to remove from the pro forma statement of earnings, King’s historical amortization expense for its intangible assets.

      (d) Represents a reclassification of King’s historical depreciation expense to cost of sales in order to conform the presentation to that of Mylan.

      (e) Represents an adjustment to eliminate King’s historical amortization expense of deferred financing costs.

      (f) Represents the income tax effect at 36% of adjustments (a)-(e) and (h)-(i).

      (g) Represents the issuance of approximately 217.3 million shares of Mylan common stock based upon an exchange ratio of 0.9 shares of Mylan common stock for each outstanding share of King common stock. This excludes the potential effect of the convertible notes since certain contingencies with respect to their conversion were not assumed to have been fulfilled and even if fulfilled, the effect would be antidilutive. If converted, Mylan would have to issue approximately 6.2 million shares of common stock.

      (h) Represents an adjustment to remove acquisition related costs from King’s historical financial statements.

      (i) Represents the amortization of the inventory step-up in fair value.

Pro Forma Balance Sheet Adjustments

      (a) Represents an adjustment to reclassify King’s estimated sales allowances (i.e. chargebacks, returns, discounts) to accounts receivable to conform to Mylan’s presentation.

      (b) Represents an adjustment to reflect the estimated fair value step-up in inventories and property, plant and equipment. Appraisals will be performed which may result in changes to the preliminary allocation of the purchase price.

      (c) Represents the preliminary adjustment to record the estimated fair value of intangible assets. The amount of intangible assets, estimated useful lives and amortization methodology are subject to the completion of an appraisal. Assuming a tax rate of 36%, for every additional $50 million allocated to intangible assets, goodwill will decrease by $32 million, intangible assets will increase by $50 million and non-current deferred income tax liabilities will increase by $18 million.

      (d) Represents an adjustment to remove King’s historical intangible assets.

      (e) Represents the preliminary adjustment to record the excess of purchase price over the fair value of net assets acquired which has been recorded as goodwill.

      (f) Represents an adjustment to remove King’s historical goodwill.

87


Table of Contents

      (g) Reflects the elimination of the historical King stockholders’ equity.

      (h) Reflects an adjustment to record the issuance of approximately 217.3 million shares of Mylan common stock in conjunction with the acquisition based upon the exchange ratio of 0.9 shares of Mylan common stock for each outstanding share of King common stock, and using an estimated price of $16.90 per share calculated as Mylan’s average stock price for the period two business days before and two business days after the July 26, 2004, announcement of the acquisition.

      (i) Represents the estimated fair value of in-process research and development acquired. Because this expense is directly attributable to the acquisition and will not have a continuing impact, it is not reflected in the unaudited condensed combined pro forma statements of earnings. However, this item will be recorded as an expense immediately following consummation of the acquisition.

      (j) Represents an adjustment to remove King’s existing debt issuance costs to reflect King’s historical debt at its estimated fair value. In determining the fair value of the debt, it was assumed that shortly after consummation of the acquisition, the holders of King’s historical debt will exercise their right to receive payment of 100% of the principal amount outstanding. As such, for purposes of these pro forma financial statements, it is assumed that fair value is equal to carrying value.

      (k) Represents deferred income taxes resulting from the pro forma adjustments made to the unaudited condensed combined pro forma balance sheet, including fair value adjustments made to historical King balance sheet amounts.

      (l) Represents an estimate of liabilities for deal and other costs related to the acquisition.

      (m) Represents capitalized acquisition costs on Mylan’s historical balance sheet. Upon consummation of the acquisition, these costs will be included in goodwill.

For Mylan’s fiscal years ended March 31, 2003 and 2002, the generic segment represented approximately 80% and 88% of net revenues, and the brand segment represented approximately 20% and 12% of net revenues.

      Prescription pharmaceutical products in the United States are generally marketed as either brand or generic drugs. Brand products are marketed under brand names through marketing programs that are designed to generate physician and consumer loyalty. Brand products generally are patent protected, which provides a period of market exclusivity during which they are sold with little or no competition. Additionally, brand products may benefit from other periods of non-patent, market exclusivity. Exclusivity generally provides brand products with the ability to maintain their profitability for relatively long periods of time. Brand products generally continue to have a significant role in the market after the end of patent protection or other market exclusivities due to physician and consumer loyalties.

      Generic pharmaceutical products are the chemical and therapeutic equivalents of reference brand drugs. A reference brand drug is an approved drug product listed in the FDA publication entitled Approved Drug Products with Therapeutic Equivalence Evaluations, popularly known as the “Orange Book.” The Drug Price Competition and Patent Term Restoration Act of 1984, which is referred to as the Waxman-Hatch Act, provides that generic drugs may enter the market after the approval of an Abbreviated New Drug Application, which is referred to as an ANDA, and the expiration, invalidation or circumvention of any patents on the corresponding brand drug, or the end of any other market exclusivity periods related to the brand drug. Generic drugs are bioequivalent to their brand name counterparts. Accordingly, generic products provide a safe, effective and cost efficient alternative to users of these brand products. Growth in the generic pharmaceutical industry has been driven by the increased market acceptance of generic drugs, as well as the number of brand drugs for which patent terms and/or other market exclusivities have expired.

Generic Segment

      Mylan is recognized as a leader in the generic pharmaceutical industry. The generic segment consists of two principal business units, Mylan Pharmaceuticals Inc., which is referred to as MPI, and UDL Laboratories, Inc., which is referred to as UDL, both of which are wholly owned subsidiaries of Mylan. MPI is Mylan’s primary generic pharmaceutical research, development, manufacturing, marketing and distribution subsidiary. MPI’s net revenues are derived primarily from the sale of solid oral dosage products. UDL packages and markets generic products, either obtained from MPI or purchased from third parties, in unit dose formats, for use primarily in hospitals and other institutions. The generic segment is augmented by transdermal patch products which are developed and manufactured by Mylan Technologies Inc., which is referred to as Mylan Tech, a wholly owned subsidiary of Mylan.

      Mylan obtains new products primarily through internal product development. Additionally, Mylan licenses or co-develops products through arrangements with other companies. New generic product approvals are obtained from the FDA through the ANDA process, which requires us to demonstrate bioequivalence to a reference brand product. Generic products are generally introduced to the marketplace at the expiration of patent protection for the brand product or at the end of a period of non-patent market exclusivity. However, if an ANDA applicant is first to file an ANDA containing a certification of invalidity, non-infringement or unenforceability related to a patent listed in the “Orange Book” with respect to a reference drug product, that generic equivalent may be able to be marketed prior to the expiration of patent protection for the brand product. Such certification, commonly referred to as a Paragraph IV certification, results in a period of generic marketing exclusivity. This exclusivity lasts for 180 days during which the FDA cannot grant final approval to any other generic equivalent.

Table of Contents

      Mylan has attained a position of leadership in the generic industry through its ability to obtain ANDA approvals, its uncompromising quality control and its devotion to customer service. Mylan has bolstered its traditional solid oral dose products with unit dose, transdermal and extended release products. Mylan has entered into strategic alliances with several pharmaceutical companies through product development, distribution and licensing agreements that provide additional opportunities to broaden its product line.

      Mylan manufactures approximately 95% of all doses sold by its generic segment. Mylan’s product portfolio consists of over 140 generic pharmaceutical products, including approximately 130 in capsule or tablet form in an aggregate of approximately 311 dosage strengths, with 14 extended release products in 30 dosage strengths of which two are transdermal patches in six dosage strengths. In addition to those products manufactured by Mylan, Mylan is marketing 57 generic products in 102 dosage strengths under supply and distribution agreements with other pharmaceutical companies. At the end of fiscal 2004, Mylan held the first or second market position in new and refilled prescriptions dispensed among all pharmaceutical companies in the U.S. with respect to approximately 70% of the generic pharmaceutical products it marketed, excluding unit-dose products.

Brand Segment

      The brand segment consists of two principal business units, Mylan Bertek Pharmaceuticals Inc., which is referred to as Mylan Bertek, and Mylan Tech, both of which are wholly owned subsidiaries of Mylan. Mylan Bertek’s principal therapeutic areas of concentration include neurology, dermatology and cardiology. The brand segment includes pharmaceutical products that have patent protection, have achieved brand recognition in the marketplace or represent branded generic pharmaceutical products that are responsive to promotional efforts.

      Nebivolol, which Mylan licensed in fiscal 2001, is a beta blocker for which Mylan submitted a New Drug Application, which is referred to as NDA, for the indication of hypertension in April 2004, and that NDA was accepted for filing by the FDA in June 2004. Mylan believes that it will be able to demonstrate clinically the unique beta 1-receptor blockade selectivity characteristics of this product, which could result in providing certain competitive advantages. As a result of recent actions taken by the U.S. Patent and Trademark Office, the nebivolol compound now has patent protection in the U.S. into 2020, which may be extended under the terms of the Waxman-Hatch Act.

      The brand segment sales force consists of approximately 200 sales representatives and managers who promote Mylan’s products to primary care physicians, dermatologists, neurologists and pharmacists.

      King’s business strategy includes the development of new branded prescription pharmaceutical products, including new chemical entities, as well as the acquisition of compounds already in development, that provide King with strategic pipeline product opportunities. King’s business strategy also includes acquiring currently marketed branded pharmaceutical products and increasing their sales through focused marketing and promotion and product life cycle management. “Product life cycle management” means the extension of the life of a product, including seeking and gaining all necessary related governmental approvals, by such means as:

Required Vote

      The issuance of Mylan common stock to King shareholders, which is necessary to effect the merger, requires the affirmative vote of at least a majority of the votes cast by all shareholders entitled to vote on the matter.

      If a proxy is returned without an indication as to how the shares of Mylan common stock represented are to be voted with regard to a particular proposal, the Mylan common stock represented by the proxy will be voted in favor of each such proposal. The proxy will confer discretionary authority to vote with respect to any matter presented at the Mylan special meeting (including adjournment or postponement thereof), except as set forth in the proxy. At the date hereof, management has no knowledge of any business that will be presented for consideration at the special meeting and which would be required to be

  •  you can grant a new, valid proxy bearing a later date;
 
  •  you can cast a new vote over the Internet or by telephone; or
 
  •  if you are a holder of record, you can attend the Mylan special meeting and vote in person, which will automatically cancel any proxy previously given, or you can revoke your proxy in person, but your attendance alone will not revoke any proxy that you have previously given.

      If you choose to send a signed notice of revocation or grant a new, valid proxy bearing a later date in writing, you must submit your notice of revocation or your new proxy to Mylan’s Secretary at 1500 Corporate Drive, Canonsburg, Pennsylvania 15317, and it must be received no later than the beginning of the Mylan special meeting.

Proposal for the Issuance of Mylan Common Stock

      It is a condition to completion of the merger that the shares of Mylan common stock issued to King shareholders in the merger be authorized for listing on the NYSE, upon official notice of issuance. Pursuant to the NYSE Listed Company Manual, as a prerequisite to listing approval, a company is required to obtain shareholder approval prior to the issuance of common stock if the common stock issued in the aggregate has voting power equal to or in excess of 20% of the voting power outstanding before such issuance of common stock. If the merger is completed, Mylan will issue approximately 217.3 million shares of Mylan common stock in the merger, or [          ]% of the voting power outstanding on the date of this joint proxy statement/ prospectus. Therefore, under the NYSE Listed Company Manual, Mylan must obtain the approval of Mylan shareholders for the issuance of shares of Mylan common stock in the merger.

      Mylan is asking its shareholders to approve the issuance of Mylan common stock to King shareholders pursuant to the merger. The issuance of Mylan common stock to King shareholders, which is necessary to effect the merger, requires approval by the affirmative vote of a majority of the votes cast by all shareholders entitled to vote on the matter.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THIS PROPOSAL UNLESS MARKED TO THE CONTRARY, PROXIES RECEIVED FROM SHAREHOLDERS WILL BE VOTED IN FAVOR OF THIS PROPOSAL.

Recent Closing Prices

      The following table sets forth the closing prices per share of Mylan common stock and King common stock as reported on the NYSE Composite Transaction Tape on July 23, 2004, the last full trading day prior to the announcement of the acquisition, and [                     ], 2004, the most recent practicable date prior to the mailing of this joint proxy statement/ prospectus to Mylan’s and King’s shareholders. This table also sets forth the equivalent price per share of King common stock on those dates. The equivalent price per share is equal to the closing price of a share of Mylan common stock on that date multiplied by 0.9, the applicable exchange ratio in the acquisition. These prices will fluctuate prior to the special meetings and the acquisition, and shareholders are urged to obtain current market quotations prior to making any decision with respect to the acquisition.

Dividend Information

      Although dividends are subject to future approval and declaration by Mylan’s and King’s respective boards of directors, Mylan currently plans to continue to pay regular quarterly dividends on its common stock until closing of the acquisition. King has never paid a cash dividend on its common stock and, under the merger agreement, King has agreed not to pay dividends pending the completion of the merger without the prior written consent of Mylan. The dividend policy of the combined company is subject to approval by Mylan’s board of directors, however, it is anticipated that Mylan will continue to pay dividends following the acquisition. Assuming Mylan’s current annual dividend of $0.12 per share and the pro forma weighted average common shares outstanding, this would equate to approximately $58.3 million annually or $14.6 million quarterly.

Shareholder Proposals and Nominations of Candidates for Election to the Board of Directors   Mylan’s bylaws allow shareholders to propose business to be brought before an annual meeting if a shareholder is a holder of record at the time of the notice of such annual meeting, is entitled to vote at such meeting and has complied with certain notice requirements described below. In addition, Mylan’s bylaws allow shareholders to nominate candidates for election to the Mylan board of directors at an annual meeting, if a shareholder is a holder of record at the time of the notice of such annual meeting, is entitled to vote for the election of directors at the annual meeting, and has complied with certain notice requirements described below.

Proposals and director nominations may only be brought before an annual meeting by a shareholder who has given timely notice in proper written form to Mylan’s Secretary prior to the meeting. To be timely, the notice must be received by the Secretary not less than 120 calendar days prior to the annual meeting, except that if a public announcement of the annual meeting date has not been made at least 75 calendar days prior to the date of the annual meeting, the shareholder’s notice must be received not later than the close of business on the 10th calendar day following the day on which the date of the annual meeting was first publicly disclosed.
  Under the TBCA, a director must discharge all duties as a director, including duties as a member of a committee, in good faith, with the care an ordinarily prudent person in a like position would exercise under similar circumstances, and in a manner the director reasonably believes to be in the best interests of the corporation. A director is not liable for any action taken as a director, or any failure to take any action, if the director performed the duties of the office in compliance with these provision of the TBCA.

        directors are to be elected, notice of the nomination must be given not later than the 10th day following the earlier of the day on which notice of the date of the meeting was mailed or public disclosure of the meeting was made.
 
Assessability   The PBCL provides that shareholders of a Pennsylvania corporation are not personally liable for debts or obligations of the corporation solely by reason of being a shareholder. However, shareholders remain personally liable for amounts they have agreed to pay for their shares of common stock.   The TBCA provides that shareholders of a Tennessee corporation are not personally liable to the corporation or its creditors except to pay the consideration that they agreed to pay for their shares or as specified in a preincorporation subscription agreement.
 
Number of Directors   The PBCL provides that the board of directors of a Pennsylvania corporation must consist of one or more directors as fixed by, or in the manner provided in, the corporation’s bylaws.

Mylan’s bylaws provide that Mylan’s board of directors may consist of no less than three directors, the exact number of authorized directors to be determined by either the board of directors or the shareholders.
  The TBCA provides that the board of directors of a Tennessee corporation must consist of one or more directors, as specified in or fixed in accordance with the corporation’s charter or bylaws.

King’s bylaws provide that King’s board of directors shall consist of eight directors, unless another number of directors is fixed by resolution of the board of directors. King’s board of directors currently has nine members.
 
Classification of Board of Directors   The PBCL permits a Pennsylvania corporation to provide for the board of directors to be divided into classes of directors with staggered terms of office. Except as otherwise provided in the articles of incorporation, if the board of directors is classified as to the term directors will serve, each class shall be as nearly equal in number as possible, the term of office of at least one class must expire in each year and the members of a class can not be elected for a longer period than four years.

Neither Mylan’s articles of incorporation nor bylaws provide for separate classes of directors.

Mylan’s bylaws provide that the shareholders shall elect a full board of directors at each annual meeting of shareholders, with each director to serve
  The TBCA permits a Tennessee corporation to provide in its charter for the terms of directors to be staggered by dividing the total number of directors into two or three groups for two-year or three-year terms.

King’s charter provides that the board of directors will be divided into three classes, as nearly equal in number as possible.

King’s charter provides that at each annual meeting of shareholders, directors elected to succeed those directors whose terms expire are elected for a three-year term, with each director to hold office until his or her successor has been duly elected and qualified.

King’s charter also provides that if the number of directors is changed, any increase or decrease shall be

    until the next annual meeting of shareholders and thereafter until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation or removal.   apportioned among the classes to maintain the number of directors in each class as nearly equal as possible.
 
Removal of Directors by Shareholders   Under the PBCL, unless a bylaw adopted by shareholders provides otherwise, shareholders may remove any director or the entire board of directors without assigning cause by the affirmative vote of a majority of the votes cast by all shareholders entitled to vote in the election of directors.

Neither Mylan’s articles of incorporation nor its bylaws modify these requirements.
  Under the TBCA, except as otherwise provided in the charter, shareholders generally may remove a director with or without cause if the number of votes cast to remove the director exceeds the number of votes cast not to remove the director.

King’s charter and bylaws do not modify these provisions of the TBCA.
 
Filling Director Vacancies   Under the PBCL, unless a corporation’s bylaws provide otherwise, vacancies and newly created directorships resulting from a resignation, an increase in the authorized number of directors or otherwise, may be filled by a vote of a majority of the directors remaining in office, even if such majority is less than a quorum, or by the sole remaining director.

Mylan’s bylaws specify that any vacancy caused by the death, resignation or removal of a director shall be filled by appointment by the Chairman of the board of directors, or in his absence, by the Vice Chairman, and a director so appointed to the board of directors shall serve for the unexpired term of the director causing such vacancy.
  Under the TBCA, unless a corporation’s charter provides otherwise, a vacancy occurring on the board of directors resulting from an increase in the number of directors or a vacancy resulting from a removal with or without cause may be filled by shareholders or by the directors remaining in office or, if the number of remaining directors is fewer than a quorum, the directors may fill the vacancy by the majority vote of all remaining directors.

King’s charter does not modify this statute.

King’s charter provides that any additional director of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term equal to the remaining term of such class.
 
Fiduciary Duties of the Board and Constituencies that Must be Considered   Under the PBCL, directors stand in a fiduciary relationship to the corporation as an entity, but not to any particular constituency.

Under the PBCL, the board of directors, in considering the best interests of the corporation, may consider to the extent they deem appropriate:
  A director of a Tennessee corporation must discharge all duties as a director, including duties as a member of a committee, in good faith, with the care an ordinarily prudent person in a like position would exercise under similar circumstances, and in a manner the director reasonably believes to be in the best interests of the corporation. In discharging such duties, a director is entitled to rely on information, opinions,

Rights of Mylan Shareholders Rights of King Shareholders


   
• The effects of any action upon any or all groups affected by such action, including shareholders, employees, suppliers, customers and creditors of the corporation, and upon communities in which offices or other establishments of the corporation are located;

• The short-term and long-term interests of the corporation, including benefits that may accrue to the corporation from its long-term plans and the possibility that these interests may be best served by the continued independence of the corporation;

• The resources, intent and conduct (past, stated and potential) of any person seeking to acquire control of the corporation; and

• All other pertinent factors.

The board of directors is not required to regard any corporate interest or the interests of any particular group affected by such action as a dominant or controlling interest or factor.

The PBCL expressly provides that the board of directors, in the discharge of its fiduciary duties, is not required to redeem any rights under or to modify or render inapplicable any shareholder rights plan, to render inapplicable statutory provisions relating to or affecting acquisitions or potential acquisitions of control, or to take action solely because of the effect of such action on a proposed acquisition or change of control of the corporation.

Director actions are presumed to be in the best interests of the corporation absent a breach of fiduciary duty, lack of good faith or self-dealing. In discharging their fiduciary duties, directors do not have any greater obligation to justify director action relating to or affecting an acquisition or a potential or proposed acquisition.
  reports or statements, including financial statements and other financial data, under certain circumstances.

Rights of Mylan Shareholders Rights of King Shareholders


    Additionally, a director is entitled to rely in good faith on information, opinions, reports or statements, including financial statements and other financial data presented or prepared by officers and employees, advisors or committees of the board.    
 
Limitation on Personal Liability of Directors   Under the PBCL, if a bylaw adopted by the shareholders of a Pennsylvania corporation so provides, a director shall not be personally liable for monetary damages for any action taken (except for liability pursuant to any criminal statute or for the payment of Federal, State or local taxes) unless the director has breached or failed to perform a fiduciary duty to the corporation and the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness.

Mylan’s bylaws include this provision.
  Under the TBCA, there is no specific provision either expressly permitting or prohibiting a corporation from limiting the liability of its directors. King’s charter eliminates personal liability of directors to the corporation or its shareholders for monetary damages for breaches of fiduciary duty, except for any breach of a director’s duty of loyalty to the corporation or its shareholders, for acts or omissions not in good faith or involving intentional misconduct or a knowing violation of the law or for unlawful distributions to shareholders.
 
Indemnification of Directors and Officers   Under the PBCL, indemnification of certain representative(s) of the corporation against expenses (including attorney’s fees) actually and reasonably incurred is mandatory to the extent that such representative has been successful on the merits or otherwise in defense of certain actions or proceedings against him or her.

The PBCL provides that a corporation may indemnify any director or officer of the corporation or person who was serving at the request of the corporation as a representative of the corporation, or is or was serving at the request of the corporation as a representative of another corporation or other enterprise against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with
  Under the TBCA, a corporation must indemnify its directors and officers against reasonable expenses incurred by the director or officer in a proceeding to which the indemnified person was a party because he or she is or was a director or officer to the extent the director or officer was wholly successful on the merits or otherwise in the defense of the proceeding.

The TBCA provides that:

• An officer who is not a director is entitled to mandatory indemnification and court-ordered indemnification to the same extent as a director;

• The corporation may indemnify and advance expenses to an officer, employee or agent of the corporation who is not a director to the same extent as to a director; and

• A corporation may also indemnify and

    respect to any criminal proceeding, had no reasonable cause to believe his conduct was unlawful.

The PBCL further provides that a corporation shall have the power to indemnify a director or an officer of the corporation or a person who is or was serving at the request of the corporation as a representative of the corporation, or is or was serving at the request of the corporation as a representative of another corporation or other enterprise against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably arising out of a derivative claim incurred by him or her if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation. Indemnification shall not be made in respect of any such derivative claim as to which the person has been adjudged to be liable to the corporation unless, and then only to the extent, the applicable court in which the action was brought determines that the person is fairly and reasonably entitled to indemnity.

Mylan’s bylaws provide for indemnification to the fullest extent authorized by law; provided, however, that Mylan shall indemnify any such indemnitee in connection with a proceeding initiated by such indemnitee only if such proceeding was authorized by the board of directors.

The PBCL permits a corporation to advance the expenses of an indemnified party, subject to the right of the corporation to recover the advanced amount under certain circumstances. Mylan’s bylaws also provide for the advancement of expenses.

The PBCL provides that a corporation shall have power to purchase and maintain insurance on behalf of any
  advance expenses to an officer, employee or agent who is not a director to the extent, consistent with public policy, that may be provided by its charter, bylaws, general or specific action of its board of directors or contract. King’s charter provides that each director, officer and employee of King shall be entitled to all indemnification rights and protections available under applicable Tennessee law.

The TBCA permits a corporation, upon request, to pay or reimburse the reasonable expenses as incurred of a director or officer who is a party to a proceeding, if the director or officer provides the corporation with a written affirmation of his or her good faith belief that he or she has not breached or failed to perform his or her duties to the corporation, the director or officer provides the corporation with a written undertaking to repay the amount advanced and a determination is made that the facts then known to those making the determination would not preclude indemnification. King’s bylaws provide that, with respect to claims of liabilities arising out of service as a director or officer of King, King shall indemnify and advance expenses to each present and future director or officer to the fullest extent allowed by the laws of the State of Tennessee.

The TBCA permits King to purchase and maintain insurance on behalf of an individual who is an employee, agent, director or officer of the corporation against liability asserted against or incurred by the individual in or arising from his or her capacity with the corporation, regardless of whether the corporation is required or authorized to indemnify or allow expenses to the individual against the same liability under the TBCA.

    person who is or was a representative of the corporation or is or was serving at the request of the corporation as a representative of another corporation or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity. Such insurance may be maintained whether or not the corporation would have the power to indemnify the insured person against such liability.

Under Mylan’s bylaws, Mylan may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of Mylan or another corporation or enterprise, whether or not Mylan has the power to indemnify such person against such liability.
   
 
Amendments to Articles of Incorporation or Charter   Under the PBCL, Mylan’s articles of incorporation generally may be amended only upon a resolution of the board of directors and the approval of the shareholders. Under the PBCL, the board of directors may make certain amendments to the articles of incorporation without shareholder approval.

The PBCL also provides that shareholders of a registered corporation, such as Mylan, are not entitled by statute to propose amendments to the articles of incorporation.

Mylan’s articles of incorporation provide that an affirmative vote of 75% of the outstanding shares of common stock entitled to vote is required to amend the articles’ provision requiring a 75% vote to approve certain interested party transactions.
  The TBCA provides that a corporation may amend its charter to add or change a required or permitted provision, or delete an optional provision. Under the TBCA, the board of directors may make certain amendments to the charter without shareholder approval. If shareholder approval is required to make the amendment, the board must generally make a recommendation regarding the adoption of the amendment and, generally, the amendment will require the approval of a majority of the votes entitled to be cast on the amendment by any voting group with respect to which the amendment would create dissenters’ rights and otherwise, if a quorum exists with respect to a voting group, by majority vote of the shareholders voting.

King’s charter does not modify the above-described provisions of the TBCA as they apply to King; however, the charter provides that neither the provisions of the charter providing for a classified board of directors, nor the provisions of the charter described in this sentence, may be amended without the affirmative vote of the holders of at

Rights of Mylan Shareholders Rights of King Shareholders


        least 80% of King’s common stock, voting together as a single class.
 
Amendments to Bylaws   Under the PBCL and Mylan’s bylaws, both the board of directors (subject to the powers of the shareholders to change such action) and the shareholders may amend the corporation’s bylaws, although the directors do not have this power with respect to matters expressly committed to the shareholders by the PBCL. The shareholders may not adopt a bylaw that varies the authority, powers and functions of the board of directors or establishes a committee of the board of directors unless the board of directors approves the adoption of the bylaw.

Mylan’s bylaws provide that they may be amended, altered and repealed, and new bylaws may be adopted, by the board of directors or by the shareholders at any regular or special meeting of the shareholders.
  The TBCA generally provides both shareholders and the board of directors with the power to amend or repeal a corporation’s bylaws, unless the charter or applicable provisions of the TBCA expressly reserve that power for the shareholders or the shareholders in amending or repealing a particular bylaw provide that the board may not amend or repeal that bylaw.

However, only shareholders may adopt or amend a bylaw that requires a higher quorum or voting requirement for shareholders, which must be adopted by the greater of the quorum and voting requirement then in effect or the proposed quorum and voting requirement.

Bylaws fixing a greater quorum or voting requirement for the board of directors may be adopted or amended only by the shareholders if the shareholders originally adopted the bylaw, and otherwise may be adopted by either the shareholders or the board of directors. Action by the board of directors to adopt or amend a bylaw originally adopted by the board of directors that changes the quorum or voting requirement for the board of directors must be adopted by the greater of the quorum and voting requirement then in effect or the proposed quorum and voting requirement.

King’s charter and bylaws do not modify the above-described provisions of the TBCA. However, King’s charter provides that neither the provisions of the bylaws providing (i) who can call a special shareholder meeting, (ii) what business may be brought before an annual shareholder meeting and (iii) the director nomination procedures, nor the provisions of the charter described in this sentence, may be

        amended without the affirmative vote of the holders of at least 80% of King’s common stock, voting together as a single class.
 
Business Combination Statute   The PBCL provides that a registered corporation may not engage in any “business combination” with an “interested shareholder” for five years after such person became an interested shareholder unless the transaction was approved by the board of directors prior to the interested shareholder’s share acquisition date or by a specified vote of shareholders.

If the combination was not previously approved, the interested shareholder may effect a combination after the five-year period only if the shareholder receives approval (A) from a majority of the shares that all shareholders of the corporation would be entitled to cast and that are not beneficially owned by the interested shareholder or (B) at a shareholders’ meeting called for such purpose, provided that the aggregate amount of the offer meets certain fair price criteria.

“Business combination” is defined broadly to include certain mergers or consolidations, share exchanges, sales or dispositions of 10% or more of the corporation’s assets, liquidations or dissolutions, and numerous other specified business combination transactions.

“Interested shareholder” means any person that is (1) the beneficial owner of shares entitling such person to cast at least 20% of the votes that all shareholders would be entitled to cast in the election of directors, or (2) an affiliate of the corporation who at any time within the five year period immediately prior to the date in question was the beneficial owner of shares entitling such person to cast at least 20% of the votes that all
  The Tennessee Business Combination Act generally prohibits a “business combination” of a resident domestic corporation or a subsidiary with a person owning 10% or more of the corporation’s voting stock for five years after that person becomes a 10% shareholder, with certain exceptions.

To effect the business combination after the expiration of the five year term, the proposed business combination must be either approved by a two-thirds vote of the non-interested shareholders, or satisfy certain fairness conditions specified by the Tennessee Business Combination Act relating to the price to be paid to the non-interested shareholders in such transaction.

An “interested shareholder” is defined by the Tennessee Business Combination Act as any person who is the beneficial owner directly or indirectly of 10% or more of the voting power of any class or series of the outstanding voting stock of the resident domestic corporation, or is an affiliate or associate of the corporation and was the direct or indirect beneficial owner of 10% or more of the voting power of any class or series of outstanding stock of the corporation at any time during the five year period prior to the date in question.

The Tennessee Business Combination Act broadly defines “business combination” to include certain mergers or consolidations, share exchanges, sales or dispositions of 10% or more of the corporation’s assets, liquidations or dissolutions, or other specified business combination transactions.

    shareholders would be entitled to cast in the election of directors.

Neither Mylan’s articles of incorporation nor its bylaws expressly opt out of the protections of Subchapter F of Chapter 25 of the PBCL relating to a business combination.
   
 
Transactions Attempting to Acquire Control   In its bylaws, Mylan has expressly opted out of the protections of Subchapter E of Chapter 25 of the PBCL, which would otherwise require persons who through a “control transaction” acquire at least 20% of the votes required for election of directors to pay objecting shareholders fair value for their shares.   The Tennessee Investor Protection Act provides that unless a corporation’s board of directors has recommended a takeover offer to shareholders, no offeror beneficially owning 5% or more of any class of equity securities of the offeree company, any of which was purchased within the preceding year, may make a tender offer for any class of equity security of the offeree company if after completion the offeror would be a beneficial owner of more than 10% of any class of outstanding equity securities of the company unless the offeror, before making such purchase,

• makes a public announcement of his or her intention with respect to changing or influencing the management or control of the offeree company;

• discloses such intention to the persons from whom he or she intends to acquire such securities; and

• files with the Tennessee Commissioner of Commerce and Insurance (referred to as the “Commissioner”) and the offeree company a statement signifying such intentions.

The offeror must provide that any equity securities of an offeree company deposited or tendered pursuant to a takeover offer may be withdrawn within a certain time period.

The Tennessee Investor Protection Act does not apply to an offer involving a vote by holders of equity securities of the offeree company, pursuant to its charter, on a merger, consolidation or

        sale of corporate assets in consideration of the issuance of securities of another corporation, or on a sale of its securities in exchange for cash or securities of another corporation.
 
Control Share Acquisition Statute   In its bylaws, Mylan has expressly opted out of the protections of Subchapter G of Chapter 25 of the PBCL, which would otherwise enable existing shareholders of Mylan in certain circumstances to block the voting rights of an acquiring person who makes or proposes to make a control-share acquisition.   Absent shareholder approval as described below, the Tennessee Control Share Acquisition Act takes away the voting rights of a purchaser’s acquired shares any time the acquisition of such shares in a Tennessee corporation causes the purchaser’s total voting power to exceed 20%, 33 1/3% or more than 50% of all voting power in such corporation (referred to as a “control share”). The purchaser’s voting rights can be maintained or re-established only by a majority vote of all the shares entitled to vote generally with respect to the election of directors other than those shares owned by the acquirer and the officers and employees of the corporation who are also directors of the corporation.

After acquiring a control share, the Tennessee Control Share Acquisition Act provides a procedure by which a purchaser may demand a special meeting of shareholders to conduct such a vote. The purchaser can demand such a meeting before acquiring a control share, but, can do so only if it holds at least 10% of outstanding shares and announces a good faith intention to make the control share acquisition. The Tennessee Control Share Acquisition Act applies only to a corporation that has adopted a provision in its charter or bylaws declaring that it will apply. King has not adopted any such provision in its charter or bylaws, and therefore is not subject to the Tennessee Control Share Acquisition Act.

Under the Tennessee Greenmail Act, King or any of its subsidiaries may not purchase any of its shares at a price above the market value of such shares from any person who holds more than 3% of the class of securities to be purchased if such person has held such shares for less than two years, unless the purchase has been approved by the affirmative vote of a majority of the outstanding shares of each class of voting stock issued by King or King makes an offer, of at least equal value per share, to all shareholders of such class.
 
Shareholder Rights Plan   Each share of Mylan common stock has attached to it a right to purchase preferred stock that becomes exercisable subject to the terms set forth in a rights agreement between Mylan and its rights agent. The Mylan board of directors adopted the rights agreement as of August 22, 1996, as amended on November 8, 1999 and on August 13, 2004.

Rights were distributed as a dividend at the rate of one right for each share of common stock outstanding at the close of business on September 5, 1996 or issued thereafter.

• Each right initially entitles shareholders to buy one one- thousandth of a share of Series A Junior Participating Preferred Stock for $40, subject to adjustment;

• The rights held by shareholders other than the potential acquiror and its affiliates become exercisable after an acquiring person has become the beneficial owner of 15% or more of the outstanding common stock of Mylan or commences a tender or exchange offer which, the consummation of which would result in an acquiring person
  Each share of King common stock has attached to it a right to purchase preferred stock that becomes exercisable subject to the terms set forth in a rights agreement between King and its rights agent. The King board of directors adopted the rights agreement in connection with the initial public offering of King’s common stock, and a registration statement on Form S-1 was filed in connection therewith on October 24, 1997. The rights agreement was amended and restated on July 23, 2004, primarily to provide an exception for the merger from several provisions of the rights agreement.

Rights were distributed as a dividend at the rate of one right for each share of common stock outstanding at the close of business on the fourth day after the effectiveness of the registration statement for King’s common stock under the Securities Act (“record date”) or issued thereafter until the date of distribution under the agreement.

• Each right initially entitles shareholders to buy one one- thousandth of a share of preferred stock for $60, subject to adjustment;

    becoming the beneficial owner of 15% or more of the outstanding common stock of Mylan. At such time, the rights become rights to purchase common stock of Mylan at a discount to the then-current market price; and

• After that, or if after public announcement that an acquiring person has become the beneficial owner of 15% or more of the outstanding common stock of Mylan, if Mylan consolidates, merges or sells 50% of its assets or earning power, the rights become exercisable (except for rights held by the acquiror) for common stock of the surviving entity at a discount to the then-current market price.

The rights are attached to the common stock unless and until they become exercisable and will expire on August 13, 2014, unless earlier redeemed by Mylan for $0.001 each or exchanged by Mylan as provided in the rights agreement.
 
• The rights held by shareholders other than the potential acquiror and its affiliates become exercisable after an acquiring person has become the beneficial owner of 15% or more of King’s outstanding common stock or commences a tender or exchange offer, the consummation of which would result in an acquiring person becoming the beneficial owner of 15% or more of King’s outstanding common stock. At such time, the rights become rights to purchase common stock of King at a discount to the then-current market price; and

• If after a person or group has acquired beneficial ownership of 15% or more of King’s outstanding common stock, and King is involved in a merger or certain other business combinations not approved by the board of directors, each right entitles its holder, other than the acquiring person or group, to purchase common stock of the surviving entity at a discount to the then-current market price.

The rights are attached to the common stock unless and until they become exercisable and will expire on the tenth anniversary of the record date, unless earlier redeemed by King for $0.01 per right and as provided in the rights agreement.

DISSENTERS’ RIGHTS

      Under Tennessee law, King shareholders will not be entitled to dissenters’ rights in connection with the merger if King common stock is listed on the NYSE at the time the merger is completed.

LEGAL MATTERS

      The validity of the shares of Mylan common stock to be issued in the merger will be passed upon for Mylan by [Pennsylvania counsel].

At or prior to the Effective Time, Parent shall engage a nationally-recognized institution reasonably satisfactory to the Company to act as exchange agent in connection with the Merger (the “Exchange Agent”). At the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Company Common Stock immediately prior to the Effective Time, certificates representing the shares of Parent Common Stock issuable pursuant to Section 2.1(a). In addition, Parent shall make available by depositing with the Exchange Agent, as necessary from time to time after the Effective Time, cash in an amount sufficient to make the payments in lieu of fractional shares pursuant to Section 2.1(e) and any dividends or distributions to which holders of shares of Company Common Stock may be entitled pursuant to Section 2.2(c). All cash and Parent Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

      (b) Exchange Procedures. Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Certificates”), which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 2.1 hereof, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration, cash in lieu of any fractional shares pursuant to Section 2.1(e) and any dividends or other distributions payable pursuant to Section 2.2(c). Upon surrender of Certificates for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificates shall be entitled to receive in exchange therefor a certificate or certificates representing that number of whole shares of Parent

Common Stock (after taking into account all Certificates surrendered by such holder) to which such holder is entitled pursuant to Section 2.1 (which shall be in uncertificated book entry form unless a physical certificate is requested), payment in lieu of fractional shares which such holder is entitled to receive pursuant to Section 2.1(e) and any dividends or distributions payable pursuant to Section 2.2(c), and the Certificates so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Parent Common Stock may be issued to a Person (as defined in Section 8.3(jj)) other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such issuance shall pay any transfer or other taxes required by reason of the issuance of shares of Parent Common Stock to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration (and any amounts to be paid pursuant to Section 2.1(e) or Section 2.2(c)) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to Section 2.1(e) or Section 2.2(c).

      (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.1(e) hereof, until such Certificate has been surrendered in accordance with this Article II. Subject to Applicable Law, following surrender of any such Certificate, there shall be paid to the recordholder thereof, without interest, (i) promptly after such surrender, the number of whole shares of Parent Common Stock issuable in exchange therefor pursuant to this Article II, together with any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.1(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock, less the amount of any withholding Taxes (as defined in Section 3.1(k)(xii)) that may be required thereon.

      (d) No Further Ownership Rights in Company Common Stock. All shares of Parent Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms of this Article II and any cash paid pursuant to Section 2.1(e) or Section 2.2(c) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such Certificates. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

      (e) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Certificates who have not theretofore complied with this Article II shall thereafter look only to Parent for payment of their claim for the Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock pursuant to Section 2.1(e) and any dividends or distributions pursuant to Section 2.2(c).

      (f) No Liability. None of Parent, Merger Sub, the Company or the Exchange Agent or any of their respective directors, officers, employees and agents shall be liable to any Person in respect of any shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to five years after the Effective Time, or

immediately prior to such earlier date on which any shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock or any dividends or distributions with respect to Parent Common Stock issuable in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 3.1(c)(v)), any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by Applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interests of any Person previously entitled thereto.

      (g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent on a daily basis; provided that no such investment or loss thereon shall affect the amounts payable to former stockholders of the Company after the Effective Time pursuant to this Article II. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this Article II shall promptly be paid to Parent.

      (h) Withholding Rights. Parent and the Exchange Agent shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to any Person who was a holder of Company Common Stock immediately prior to the Effective Time such amounts as Parent or the Exchange Agent may be required to deduct and withhold with respect to the making of such payment under the Code or any other provision of federal, state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person to whom such consideration would otherwise have been paid.

      (i) Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such shares of Parent Common Stock as may be required pursuant to Section 2.1(a), cash for fractional shares pursuant to Section 2.1(e) and any dividends or distributions payable pursuant to Section 2.2(c); provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver an agreement of indemnification in form reasonably satisfactory to Parent, or a bond in such sum as Parent may reasonably direct as indemnity, against any claim that may be made against Parent or the Exchange Agent in respect of the Certificates alleged to have been lost, stolen or destroyed.

      (j) Affiliates. Notwithstanding anything to the contrary herein, to the fullest extent permitted by Applicable Law, no certificates representing shares of Parent Common Stock shall be delivered to a Person who may be deemed an “affiliate” of the Company in accordance with Section 5.13 hereof for purposes of Rule 145 under the Securities Act of 1933, as amended (the “Securities Act”), and the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) thereunder until such Person has executed and delivered an Affiliate Agreement (as defined in Section 5.13) to Parent.

ADDITIONAL AGREEMENTS

     

SECTION 5.1     Preparation of SEC Documents; Stockholders’ Meetings.

      (a) As soon as practicable following the date of this Agreement, Parent and the Company shall prepare and file with the SEC the Joint Proxy Statement, and Parent shall prepare and file with the SEC the Form S-4, in which the Joint Proxy Statement will be included as a prospectus. Each of Parent and the Company shall use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing. Parent will use its reasonable best efforts to cause the Joint Proxy Statement to be mailed to Parent’s stockholders, and the Company will use its reasonable best efforts to cause the Joint Proxy Statement to be mailed to the Company’s stockholders, in each case as promptly as practicable after the Form S-4 is declared effective under the Securities Act. Parent shall also take any action (other than qualifying to do business in any jurisdiction in which it is not now so qualified or to file a general consent to service of process) required to be taken under any applicable state securities laws in connection with the issuance of shares of Parent Common Stock in the Merger and the conversion of Company Options into options to acquire Parent Common Stock, and the Company shall furnish all information concerning the Company and the holders of Company Common Stock as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Joint Proxy Statement will be made by Parent or the Company without the other party’s prior consent (which shall not be unreasonably withheld or delayed) and without providing the other party the opportunity to review and comment thereon. Parent will advise the Company, promptly after it receives notice thereof, of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, or the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, and each party will advise the other promptly of any request by the SEC for amendment of the Joint Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information. If at any time prior to the Effective Time any information (including any Company Change of Recommendation or Parent Change of Recommendation) relating to Parent or the Company, or any of their respective Affiliates, officers or directors, should become known to Parent or the Company which should be set forth in an amendment or supplement to any of the Form S-4 or the Joint Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the stockholders of Parent and the Company.

      (b) Each of the Company and Parent shall, as promptly as practicable after the Form S-4 is declared effective under the Securities Act, take all action necessary in accordance with Applicable Law and the

A-42


Table of Contents

Company Organizational Documents, in the case of the Company, and the Parent Organizational Documents, in the case of Parent, to duly give notice of, convene and hold a meeting of its stockholders as promptly as practicable to consider, in the case of Parent, the Stock Issuance (the “Parent Stockholders’ Meeting”) and, in the case of the Company, the adoption and approval of this Agreement and the Merger (the “Company Stockholders’ Meeting”). Unless there has been a Company Change of Recommendation (in the case of the Company) or Parent Change of Recommendation (in the case of Parent), as the case may be, each of the Company and Parent will use its reasonable best efforts to solicit from its stockholders proxies in favor of, in the case of Parent, the Stock Issuance, and, in the case of the Company, the adoption and approval of this Agreement and the Merger, and will take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of the NYSE or Applicable Law to obtain such approvals. Notwithstanding anything to the contrary contained in this Agreement, the Company or Parent may adjourn or postpone the Company Stockholders’ Meeting or Parent Stockholders’ Meeting, as the case may be, to the extent necessary to ensure that any necessary supplement or amendment to the Joint Proxy Statement is provided to its respective stockholders in advance of a vote on, in the case of Parent, the Stock Issuance, and, in the case of the Company, the approval and adoption of this Agreement and the Merger, or, if, as of the time for which the Company Stockholders’ Meeting or Parent Stockholders’ Meeting, as the case may be, is originally scheduled, there are insufficient shares of Company Common Stock or Parent Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting. Unless there has been a Company Change of Recommendation (in the case of the Company) or a Parent Change of Recommendation (in the case of Parent), each of the Company and Parent shall ensure that the Company Stockholders’ Meeting and the Parent Stockholders’ Meeting, respectively, is called, noticed, convened, held and conducted, and that all proxies solicited in connection with the Company Stockholders’ Meeting or Parent Stockholders’ Meeting, as the case may be, are solicited in compliance with Applicable Law, the rules of the NYSE and, in the case of the Company, the Company Organizational Documents, and, in the case of Parent, the Parent Organizational Documents. Without the prior written consent of Parent, approval and adoption of this Agreement and the Merger is the only matter which the Company shall propose to be acted on by the Company’s stockholders at the Company Stockholders’ Meeting. Without the prior written consent of the Company (not to be unreasonably withheld or delayed), approval of the Stock Issuance is the only matter which Parent shall propose to be acted on by Parent’s stockholders at the Parent Stockholders’ Meeting.

      (c) Unless there has been a Company Change of Recommendation (in the case of the Company) or a Parent Change of Recommendation (in the case of Parent), each of the Company and Parent will use its reasonable best efforts to hold the Company Stockholders’ Meeting and Parent Stockholders’ Meeting, respectively, on the same date as the other party and as soon as reasonably practicable after the date of this Agreement.

      (d) Unless there has been a Company Change of Recommendation (in the case of the Company) or a Parent Change of Recommendation (in the case of Parent): (i) the Board of Directors of each of the Company and Parent shall recommend that its stockholders vote in favor of, in the case of the Company, the approval and adoption of this Agreement and the Merger at the Company Stockholders’ Meeting, and, in the case of Parent, the Stock Issuance at the Parent Stockholders’ Meeting, (ii) the Joint Proxy Statement shall include a statement to the effect that the Board of Directors of (A) Parent has recommended that Parent’s stockholders vote in favor of the Stock Issuance at the Parents’ Stockholder Meeting and (B) the Company has recommended that the Company’s stockholders vote in favor of approval and adoption of this Agreement and the Merger at the Company Stockholders’ Meeting and (iii) neither the Board of Directors of the Company or Parent nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to the other party, the recommendation of its respective Board of Directors that the respective stockholders of the Company or Parent vote in favor of, in the case of the Company, the approval and adoption of this Agreement and the Merger, and, in the case of Parent, the Stock Issuance.

      (b) Parent and the Company will each use its reasonable best efforts to cause to be delivered to each other consents from their respective independent auditors, dated the date on which the Form S-4 shall become effective or a date not more than two days prior to such date, in form reasonably satisfactory to the recipient and customary in scope and substance for consents delivered by independent public accountants in connection with registration statements on Form S-4 under the Securities Act.

     

SECTION 5.3     Access to Information; Confidentiality. Subject to the CDA and Applicable Law, the Company shall, and shall cause each of its Subsidiaries to, afford to Parent and its officers, employees, accountants, counsel, financial advisors and other representatives, full access at all reasonable times on reasonable notice during the period prior to the Effective Time to all their properties, books, contracts, commitments, personnel and records (provided, that such access shall not unreasonably interfere with the business or operations of the Company) and, during such period, the Company shall, and shall cause each of its Subsidiaries to, furnish promptly to Parent (i) a copy of each report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of federal or state securities laws, and (ii) all other information concerning its business, properties, litigation matters and personnel as Parent may reasonably request provided, that nothing in Section 5.3(a), (b) or (c) shall require the Company to provide any access, or to disclose any information, if permitting such access or disclosing such information would (a) violate Applicable Law, (b) violate any of its obligations with respect to confidentiality (provided that the Company shall, upon the request of Parent, use its reasonable best efforts to obtain the required consent of any third party to such access or disclosure), or (c) result in the loss of attorney-client privilege (provided that the Company shall use its reasonable best efforts to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege). The Company also will consult with Parent regarding its business in a prompt manner and on a regular basis. In addition, the Company and its officers and employees shall reasonably cooperate with Parent in Parent’s efforts to comply with the rules and regulations affecting public companies, including SOX. No review pursuant to this Section 5.3 shall affect or be deemed to modify any representation or warranty contained herein, the covenants or agreements of the parties hereto or the conditions to the obligations of the parties hereto under this Agreement.

      (b) In addition, without limiting the foregoing, prior to the first date on which both the Company Stockholder Approval and the Parent Stockholder Approval have been obtained, the Company shall use its reasonable best efforts (x) to provide Parent with sufficient advance notice of intended written or electronic communications with the Investigating Entities, plaintiff’s counsel in the Shareholder and Derivative Actions and the Company’s insurers regarding coverage of any claims or potential claims related either to the Investigations or the Shareholder and Derivative Actions (“Intended Communications”) to allow Parent to review and comment upon such communications, and (y) to permit one outside lawyer for Parent (who shall be reasonably acceptable to the Company) to attend, solely in a monitoring capacity, proposed in-person or telephonic communications (“Proposed Meetings”) with the Investigating Entities and/or plaintiff’s counsel in the Shareholder and Derivative Actions, unless in either case the Company reasonably believes that such advance notice or such attendance would adversely affect its ability to resolve such matters on favorable terms. From and after the first date on which both the Company Stockholder Approval and the Parent Stockholder Approval have been obtained, (x) the Company shall be required to provide Parent with sufficient advance notice of Intended Communications to allow Parent to review and comment upon such communications (provided that the Company shall not be required to delay any Intended Communication pending comment from Parent in the event that the Company reasonably believes that such delay would significantly impact its ability to resolve the relevant matter), and (y) the

A-44

Company shall use its reasonable best efforts to give Parent advance notice of any Proposed Meetings and to permit Parent and its representatives approved in advance by the Company to attend and participate in a reasonable manner in such meetings (provided that Parent shall not insist on attendance at Proposed Meetings if the Investigating Entities have requested in writing that Parent not participate). The Company shall consider in good faith the views and comments of Parent and its Representatives with respect to all Intended Communications and Proposed Meetings. To the extent that the Company shall not have been required by this Section 5.3(b) to have afforded Parent advance notice of any Intended Communication or an opportunity to attend any Proposed Meeting, the Company shall without unreasonable delay inform Parent of all communications (whether oral, in writing, electronic, or otherwise) with (1) the Investigating Entities in connection with the Investigations of the Company; (2) plaintiffs’ counsel in the Shareholder and Derivative Actions; and (3) the Company’s insurers regarding coverage of any claims or potential claims related either to the investigations by the Investigating Entities or the Shareholder and Derivative Actions. Notwithstanding the foregoing or anything else in this Agreement to the contrary, the Company shall not be required to take any action that would violate any Applicable Law or to make any disclosure to Parent or any other Person that would result in a loss of the protection of the attorney client and work product privileges. In connection with this Section 5.3(b), Parent represents that, based upon all information made available to it as of the date of this Agreement, it currently expects to cooperate with the Investigating Entities in a manner substantially consistent with the cooperation afforded the Investigating Entities by the Company, but nothing in this sentence shall in any way limit Parent’s discretion with respect to the Investigating Entities after the Closing Date.

      (c) Upon reasonable request and notice, Parent will provide the Company reasonable access to its properties, books, contracts, commitments, personnel and records, and Parent will respond to reasonable inquiries from the Company regarding its business operations on a regular basis; provided, that the foregoing shall not require Parent to respond, or to disclose any information if responding or disclosing such information would (a) violate Applicable Law, (b) violate any of its obligations with respect to confidentiality (provided that Parent shall, upon the request of the Company, use its reasonable best efforts to obtain the required consent of any third party to such access or disclosure), or (c) result in the loss of attorney-client privilege (provided that Parent shall, upon the request of the Company, allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege).

      (d) Each of Parent and the Company will hold, and will cause its respective officers, employees, accountants, counsel, financial advisors and other representatives and Affiliates to hold, any nonpublic information in accordance with the terms of the CDA.

      SECTION 5.4     Antitrust Filings; Reasonable Best Efforts.

      (a) Each party shall make or cause to be made, in cooperation with the other parties and to the extent applicable and as promptly as practicable, (i) an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby and (ii) all other necessary filings, forms, declarations, notifications, registrations and notices with other Governmental Entities under Competition Laws relating to the transactions contemplated hereby. “Competition Laws” mean the HSR Act, the Sherman Antitrust Act of 1890, as amended, the Clayton Act of 1914, as amended, the Federal Trade Commission Act, as amended, and any other United States federal or state or foreign statutes, rules, regulations, orders, decrees, administrative or judicial doctrines or other laws that are designed to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade. Each party shall use its reasonable best efforts to respond at the earliest practicable date to any requests for additional information made by the Federal Trade Commission (the “FTC”), the United States Department of Justice (the “DOJ”) or any other Governmental Entities, and act in good faith and reasonably cooperate with the other party in connection with any investigation of any Governmental Entity. Each party shall use its reasonable best efforts to furnish to each other all information required for any filing, form, declaration, notification, registration and notice. Each party shall give the other party reasonable prior notice of any communication with, and any proposed understanding or agreement with, any Governmental Entity regarding any filings, forms, declarations, notifications, registrations or notices, and permit the other to review and discuss in advance, and consider in good faith

A-45


Table of Contents

the views of the other in connection with, any proposed communication, understanding or agreement with any Governmental Entity with respect to the transactions contemplated by the Agreement. None of the parties shall independently participate in any meeting, or engage in any substantive conversation, with any governmental authority in respect of any filings or inquiry without giving the other party prior notice of the meeting and, unless prohibited by such Governmental Entity, the opportunity to attend and/or participate. The parties will consult and cooperate with one another in connection with any information or proposals submitted in connection with proceedings under or relating to any Competition Law. Without limiting the foregoing, the Company and Parent shall each use its reasonable best efforts: (i) to avoid the entry of any judgment that would restrain, prevent or delay the Closing; (ii) to eliminate every impediment under any Competition Law that may be asserted by any Governmental Entity so as to enable the Closing to occur as soon as reasonably possible (and in any event no later than the Outside Date); and (iii) vigorously to contest and resist any such action or proceeding, including any administrative or judicial action.

      (b) Subject to Section 5.4(c), each of the parties to this Agreement agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties to this Agreement in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including (i) the obtaining of all other necessary actions or nonactions, waivers, consents, licenses, permits, authorizations, orders and approvals from Governmental Entities and the making of all other necessary registrations and filings (including filings with Governmental Entities, if any), (ii) the obtaining of all consents, approvals or waivers from third parties related to or required in connection with the Merger that are necessary to consummate the Merger and the transactions contemplated by this Agreement, (iii) the preparation of the Joint Proxy Statement and the Form S-4, (iv) the execution and delivery of any additional instruments reasonably necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement, and (v) the providing of all such information concerning such party, its subsidiaries, its Affiliates and its subsidiaries’ and Affiliates’ officers, directors, employees and partners as may be reasonably requested in connection with any of the matters set forth in Section 5.4(a) or this Section 5.4(b). Each of Parent and the Company agrees that it will use its reasonable best efforts to obtain prior to the Effective Time each of the consents that are listed in Section 5.4(b) of the Company Disclosure Letter.

      (c) Notwithstanding anything to the contrary in this Section 5.4, neither Parent nor the Company shall be required in order to resolve any objections asserted under Competition Laws by any Governmental Entity with respect to the transactions contemplated by this Agreement to divest any of its businesses, product lines or assets, or take or agree to take any other action or agree to any limitation or restriction, that is reasonably likely to result in a Parent Material Adverse Effect (determined, for purposes of this clause, after giving effect to the Merger) or a Company Material Adverse Effect.

      (d) The Company and Parent shall not, and shall not permit any of their respective subsidiaries to, acquire or agree to acquire by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business or any corporation, partnership, association or other business organization or division thereof, or otherwise acquire or agree to acquire any assets if the entering into of a definitive agreement relating to or the consummation of such acquisition, purchase, merger or consolidation is reasonably expected to (i) impose any delay (other than an immaterial delay) in the obtaining of, or increase the risk (other than an insignificant increase) of not obtaining, any authorizations, consents, orders, declarations or approvals of any Governmental Entity necessary to consummate the transactions contemplated by this Agreement or the expiration or termination of any applicable waiting period, (ii) increase the risk (other than an insignificant increase) of any Governmental Entity entering an order prohibiting the consummation of the transactions contemplated by this Agreement or commencing litigation seeking such an order, (iii) increase the risk (other than an insignificant increase) of not being able to remove any such order on appeal or otherwise, (iv) delay (other than an immaterial delay) or prevent the consummation of the transactions contemplated by this Agreement, or (v) increase the risk (other than an insignificant increase) of any of the conditions to the Merger set forth in VI not being satisfied.

SECTION 5.5     Indemnification(a). From and after the Effective Time, Parent shall cause the Surviving Corporation to indemnify, defend and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time, a director or officer of the Company or any of its Subsidiaries (the “Indemnified Parties”) against all losses, claims, damages, costs and expenses (including reasonable attorneys’ fees), liabilities, judgments and, subject to the proviso of this sentence, settlement amounts that are paid or incurred in connection with any pending, threatened or completed claim, action, suit, proceeding or investigation (whether civil, criminal, administrative or investigative and whether asserted or claimed prior to, at or after the Effective Time) that is (i) based on, or arises out of, the fact that such Indemnified Party is or was a director or officer of the Company or any of its Subsidiaries, or (ii) based on, or arising out of, or pertaining to this Agreement or the transactions contemplated hereby, in each case to the fullest extent a corporation is permitted under Applicable Law to indemnify its own directors or officers, as the case may be (“Indemnified Liabilities”). Without limiting the foregoing, in the event that any such claim, action, suit, proceeding or investigation is brought against any Indemnified Party (whether arising prior to or after the Effective Time), (x) the Surviving Corporation shall have the right to assume the defense thereof with legal counsel of Parent’s choosing and neither Parent nor the Surviving Corporation shall be liable to such Indemnified Party for any legal expenses of other counsel or any expenses subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however that such Indemnified Party may employ counsel of its own choosing, and Parent shall cause the Surviving Corporation to pay such Indemnified Party for reasonable legal expenses of such counsel, if under applicable standards of professional conduct the counsel selected by Parent would have a conflict representing the Surviving Corporation and the Indemnified Party in the conduct of the defense of an action; (y) the Indemnified Party shall cooperate with the Surviving Corporation in the defense of any such matter; and (z) the Surviving Corporation shall not be liable for any settlement of any claim effected without its written consent (which consent shall not be unreasonably withheld or delayed). Any Indemnified Party wishing to obtain indemnification under this Section 5.5(a), upon learning of any claim, action, suit, proceeding or investigation, shall promptly notify Parent thereof; provided, however, the failure of any Indemnified Party to give such notice shall not waive any rights of the Indemnified Party under this Section 5.5 except to the extent that the rights of the Surviving Corporation or Parent are actually materially prejudiced thereby). In the event the Surviving Corporation does not assume the defense of an action in accordance with this Section 5.5(a), (A) the Indemnified Parties as a group seeking indemnification with respect to the same or a substantially related matter may retain only one law firm with respect to such matter except to the extent that under applicable standards of professional conduct, such counsel would have a conflict representing such Indemnified Party and any other Indemnified Party or Indemnified Parties; (B) Parent shall cause the Surviving Corporation to pay all expenses of the disposition of any such claim, action, suit, proceeding or investigation to each Indemnified Party to the full extent permitted by Applicable Law promptly after statements therefor are received and otherwise advance to such Indemnified Party upon request reimbursement of documented expenses reasonably incurred, in either case to the extent not prohibited by the TBCA; provided, however, that the person to whom expenses are advanced provides an undertaking required by Applicable Law to repay such advance if it is ultimately determined that such person is not entitled to indemnification; (C) the Indemnified Parties shall retain counsel reasonably satisfactory to the Surviving Corporation; (D) Parent shall cause the Surviving Corporation to pay all reasonable fees and expenses of such counsel for the Indemnified Parties and all costs and expenses of the Indemnified Parties in connection with seeking and obtaining indemnification from the Surviving Corporation, in each case promptly as statements therefor are received; and (E) Parent shall cause the Surviving Corporation to use reasonable best efforts to assist in the defense of any such matter. In the event of any dispute as to whether an Indemnified Party’s conduct complies with the standards set forth under the TBCA and the Company Charter or Company Bylaws, a determination shall be made by independent counsel mutually acceptable to the Company following the Effective Time and the Indemnified Party (the “Independent Counsel”); provided, however, that the Surviving Corporation shall not be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld or delayed). Without limiting the foregoing, to the extent that any Indemnified Party is, by reason of the fact that such Indemnified Party is or was a director or officer of the Company or any of its Subsidiaries, a witness in any claim, action, suit,

A-47


Table of Contents

proceeding or investigation to which such Indemnified Party is not a party, such Indemnified Party shall be indemnified and held harmless against all costs and expenses in connection therewith.

        (ii) The Surviving Corporation shall not enter into any settlement of any claim in which the Surviving Corporation is jointly liable with an Indemnified Party (or would be if joined in such claim) unless such settlement provides for a full and final release of all claims asserted against such Indemnified Party.

      (b) Except to the extent required by Applicable Law, neither Parent nor the Surviving Corporation shall take any action so as to amend, modify, limit or repeal the provisions for indemnification of Indemnified Parties contained in the certificates or articles of incorporation or bylaws (or other comparable charter documents) of the Surviving Corporation and its Subsidiaries (which as of the Effective Time shall be no more favorable to such individuals than those maintained by the Company and its Subsidiaries on the date hereof) in such a manner as would adversely affect the rights of any Indemnified Party to be indemnified by such corporations in respect of their serving in such capacities prior to the Effective Time. The Surviving Corporation shall honor all of its indemnification obligations existing as of the Effective Time.

      (c) For a period of six years after the Effective Time, Parent shall cause to be maintained in effect the policies of directors’ and officers’ liability insurance maintained by the Company as of the date of this Agreement; provided, however, that Parent may substitute therefor policies of at least the same coverage containing terms that are no less advantageous with respect to matters occurring prior to or at the Effective Time, or Parent may expand its own directors’ and officers’ liability insurance policy to provide the same coverage as maintained by the Company as of the date of this Agreement and on terms that are no less advantageous with respect to matters occurring prior to or at the Effective Time, in each case to the extent such liability insurance or additional coverage can be maintained annually at a cost to the Surviving Corporation not greater than 300% for annual premiums for such directors’ and officers’ liability insurance, which existing premium costs are set forth in Section 5.5(c) of the Company Disclosure Letter; provided, further, that if such insurance or additional coverage cannot be so maintained or obtained at such cost, the Company shall maintain or obtain as much of such insurance as can be so maintained or obtained at a cost equal to 300% of the current annual premiums of the Company for its directors’ and officers’ liability insurance.

      (d) The provisions of this Section are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and each party entitled to insurance coverage under Section 5.5(c), respectively, and his or her heirs and legal representatives, and shall be in addition to, and shall not impair, any other rights an Indemnified Party may have under the Company Charter, the Company Bylaws or the comparable organization documents of the Surviving Corporation or any of its Subsidiaries, under the TBCA or otherwise. Parent shall ensure that the Surviving Corporation complies with all of its obligations under this Section 5.5.

     

SECTION 5.6     Employee Benefits.

      (a) Immediately following the Effective Time and until December 31, 2005, Parent will provide, or will cause to be provided, to each person who is employed by the Company or any of its Subsidiaries immediately prior to the Effective Time and who continues to be employed by Parent, the Surviving Corporation, or any of their Subsidiaries (the “Continuing Employees”) (i) compensation and benefits which in the aggregate are no less favorable than those provided by the Company and its Subsidiaries to such Continuing Employee immediately prior to the Effective Time under the applicable Company Benefit Plans, Company Benefit Agreements and compensation practices of the Company and its Subsidiaries and (ii) eligibility for periodic increases in compensation and/or promotions generally consistent with then current policies of Parent and its Subsidiaries for employees of Parent and its Subsidiaries who are employed in comparable positions.

      (b) For a period of two years following the Effective Time, Parent will provide, or will cause to be provided, severance benefits (based on the change in control that will occur at the Effective Time in

A-48


Table of Contents

accordance with the terms of the Company’s severance policy) to Continuing Employees which are no less favorable than those provided under the Company’s severance policy attached to Section 5.6(b) of the Company Disclosure Letter (the “Company Severance Policy”); provided, however, that notwithstanding anything in the Company Severance Policy to the contrary, equity awards granted to any Continuing Employee following the Effective Time shall be governed by the terms and conditions of the award agreement(s) issued under the applicable Parent equity plans. Parent will comply, and will cause the Surviving Corporation to comply, with the obligations set forth in Section 5.6(b) of the Company Disclosure Letter.

      (c) From and after the Effective Time, each Continuing Employee shall be eligible to participate in Parent’s vacation policies; provided, however, that the amount of vacation days per year for each Continuing Employee shall be no less than the amount of vacation days such Continuing Employee would have been entitled to as of Effective Time under the applicable Company Benefit Plans or Company Benefit Agreements.

      (d) For a period of two years following the Effective Time, the Continuing Employees will be eligible to participate in all stock option, bonus, profit-sharing and similar plans of Parent and/or its Subsidiaries to the same extent as employees of Parent and/or its Subsidiaries who are employed in comparable positions.

      (e) With respect to each benefit plan of Parent or any of its Subsidiaries in which Continuing Employees are eligible to participate following the Effective Time, for purposes of determining vesting and entitlement to benefits, including for severance benefits and vacation entitlement (but not for purposes of defined benefit pension accruals), service with the Company and its Subsidiaries (or predecessor employers to the extent the Company and its Subsidiaries recognize such past service) shall be treated as service with Parent and its Subsidiaries; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or to the extent that such service was not recognized under the applicable Company Benefit Plan or Company Benefit Agreement.

      (f) Following the Effective Time, Parent shall, or shall cause its Subsidiaries to (i) waive any pre-existing conditions, exclusions, actively-at-work requirements and waiting periods under any benefit plan maintained by Parent or any of its Subsidiaries for each Continuing Employee and his or her eligible dependents (except to the extent that such pre-existing conditions, exclusions, actively-at-work requirements and waiting periods would have been applicable under the comparable benefit plans of the Company and its Subsidiaries immediately prior to the Effective Time) and (ii) provide each Continuing Employee and his or her eligible dependents with full credit for any co-payments and deductibles incurred prior to the Effective Time (or any later transition date to new welfare benefit plans) for the calendar year in which the Effective Time (or such later transition date) occurs, in satisfying any applicable deductible or out-of-pocket requirements under any welfare benefit plans that such persons participate in after the Effective Time.

      (g) Parent will, and will cause its Subsidiaries to, honor, in accordance with their respective terms, the Company Benefit Plans and Company Benefit Agreements, including any rights or benefits arising as a result of the transactions contemplated by this Agreement (either alone or in combination with any other event); provided, however, that, subject to compliance with their obligations in this Section 5.6, Parent, the Surviving Corporation and their Subsidiaries may amend or terminate the Company Benefit Plans and Company Benefit Agreements in accordance with their terms as in effect immediately prior to the Effective Time.

      (h) Parent agrees that certain employee matters shall be governed in accordance with the provisions of Section 5.6(h) of the Company Disclosure Letter.

     

SECTION 5.7     Fees and Expenses. Except as set forth in this Section 5.7 and in Section 7.3, all fees and expenses incurred in connection with the Merger, this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated, except that each of the Company and Parent shall bear and pay one-half of the costs and

A-49


Table of Contents

expenses incurred by Parent, Merger Sub or the Company (other than attorneys’ fees, accountants’ fees and related expenses) in connection with (i) the filing, printing and mailing of the Form S-4 (including financial statements and exhibits), the Joint Proxy Statement (including SEC filing fees) and any preliminary materials related thereto and (ii) the filings of the premerger notification and report forms under the Antitrust Laws (including filing fees).

     

SECTION 5.8     Public Announcements. The Company and Parent will consult with each other before issuing, and will provide each other the opportunity to review, comment upon and concur with, and use reasonable best efforts to agree on, any press release or other public statements with respect to the transactions contemplated by this Agreement, including the Merger, and shall not issue any such press release or make any such public statement prior to such consultation, except as either party may determine is required by Applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or stock market. The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the parties.

     

SECTION 5.9     Listing. Parent shall use its reasonable best efforts to cause the Parent Common Stock issuable under Article II, and those shares of Parent Common Stock required to be reserved for issuance in connection with the Merger (including under the Company Stock Plans), to be authorized for listing on the NYSE, upon official notice of issuance.

     

SECTION 5.10     Tax-Free Reorganization Treatment. Parent and the Company hereby adopt this Agreement as a plan of reorganization within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a). Parent and the Company intend that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code, and each shall, and shall cause its respective Subsidiaries to, use its reasonable best efforts to cause the Merger to so qualify and to obtain the opinions of counsel referred to in Section 6.1(g), including the execution of the certificates referred to therein. Neither Parent nor the Company shall take any action, or fail to take any action, that is reasonably likely to cause the Merger to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code.

     

SECTION 5.11     Conveyance Taxes. The Company and Parent shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp taxes, any transfer, recording, registration and other fees or any similar taxes which become payable in connection with the transactions contemplated by this Agreement that are required or permitted to be filed on or before the Effective Time. The Company shall pay on behalf of its stockholders any such Taxes or fees which become payable in connection with the transactions contemplated by this Agreement for which such stockholders are primarily liable and in no event shall Parent pay such amounts.

     

SECTION 5.12     Equity Awards.

      (a) At the Effective Time, each Company Option outstanding immediately prior to the Effective Time, whether or not exercisable at the Effective Time, will be assumed by Parent. Each Company Option so assumed by Parent under this Agreement will continue to have, and be subject to, the same terms and conditions set forth in the applicable Company Option (including any applicable stock option agreement or other document evidencing such Company Option) immediately prior to the Effective Time (including any repurchase rights or vesting provisions), except that (i) each Company Option will be exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock that were issuable upon exercise of such Company Option immediately prior to the Effective Time (disregarding any vesting schedule applicable to such option) multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Option will be equal to the quotient determined by dividing the exercise price per share of Company Common Stock of such Company Option by the Exchange Ratio, rounded up to the nearest whole cent. The Company shall take all corporate action necessary, including amending any Company Option or Company Benefit Plan, to effectuate the

A-50


Table of Contents

foregoing. Each assumed Company Option shall be exercisable immediately following the Effective Time as to the same percentage of the total number of shares as to which it was exercisable immediately prior to the Effective Time, except to the extent such Company Option (either by its terms or by the terms of another agreement) provides for automatic acceleration of vesting. Prior to the Effective Time, Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery in connection with the exercise of the converted Company Options.

      (b) The parties shall use their reasonable best efforts to ensure that the conversion of any Company Options which are intended to be “incentive stock options” (as defined in Section 422 of the Code) as provided for in this Section 5.12 shall be effected in a manner consistent with Section 424(a) of the Code.

      (c) As soon as practicable after the Effective Time, Parent shall deliver to the holders of Company Options appropriate notices setting forth such holders’ rights pursuant to the respective Company Stock Plans and the agreements evidencing the grants of such Company Options shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 5.12 after giving effect to the Merger).

      (d) At or prior to the Effective Time, Parent shall file a registration statement on an appropriate form with respect to the shares of Parent Common Stock subject to such Company Options and shall use reasonable best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Company Options remain outstanding.

      (e) Parent and the Company agree that, in order to most effectively compensate and retain Company Insiders (as defined below) in connection with the Merger, both prior to and after the Effective Time, it is desirable that the conversion of Company Common Stock and Company Options into shares of Parent Common Stock and Parent Options in connection with the Merger be exempted from risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by Applicable Law, and for that compensatory and retentive purpose Parent and the Company agree to the provisions of this Section 5.12(e). Assuming that the Company delivers to Parent the Section 16 Information (as defined below) in a timely fashion, the Board of Directors of Parent, or a committee of Non-Employee Directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall adopt a resolution providing that the receipt by Company Insiders of Parent Common Stock in exchange for Company Common Stock, and of Parent Options upon conversion of Company Options, in each case pursuant to the transactions contemplated by this Agreement and to the extent such securities are listed in the Section 16 Information, are intended to be exempt from liability pursuant to Section 16(b) under the Exchange Act in accordance with the procedures set forth in Rule 16b-3 promulgated under the Exchange Act and the Skadden, Arps, Slate, Meagher & Flom LLP SEC No-Action Letter (January 12, 1999). “Section 16 Information” shall mean information accurate in all material respects regarding Company Insiders, the number of shares of Company Common Stock held by each such Company Insider and expected to be exchanged for Parent Common Stock in the Merger, and the number and description of the Company Options held by each such Company Insider and expected to be converted into Parent Options in connection with the Merger; provided that a description of any Company Options shall not be required if copies of all Company Stock Plans under which such Company Options have been granted, and forms of agreements evidencing grants thereunder, have been made available to Parent. “Company Insiders” shall mean those officers and directors of Company who may be subject to the reporting requirements of Section 16(a) of the Exchange Act on or following the Effective Time and who are listed in the Section 16 Information.

     

SECTION 5.13     Affiliates. Not less than 45 days prior to the Effective Time, the Company shall deliver to Parent a letter identifying all Persons who, in the judgment of the Company, may be deemed at the time this Agreement is submitted for adoption by the stockholders of the Company, “affiliates” of the Company for purposes of Rule 145 under the Securities Act and applicable SEC rules and regulations, and such list shall be updated as necessary to reflect changes from the date thereof. The Company shall use its reasonable best efforts to cause each Person identified on such list to deliver to Parent not less than

A-51


Table of Contents

SECTION 8.9     Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by either of the parties hereto without the prior written consent of the other party.

SECTION 8.11     Headings, etc. The headings and table of contents contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 8.12     Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect, insofar as the foregoing can be accomplished without materially affecting the economic benefits anticipated by the parties to this Agreement. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by Applicable Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

     

SECTION 8.13     Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or delay on the part of any party hereto in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

     

SECTION 8.14     Waiver of Jury Trial. Each of parent, merger sub and the Company hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this agreement or the transactions contemplated hereby or the actions of parent, merger sub or the Company in the negotiation, administration, performance and enforcement of this agreement.

     

SECTION 8.15     Specific Performance. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any federal court located in the State of New York or in New York state court, this being in addition to any other remedy to which they are entitled at law or in equity.

ANNEX B

OPINION OF MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED

[LETTERHEAD OF MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED]

  July 23, 2004

Board of Directors

Mylan Laboratories Inc.
1500 Corporate Drive, Suite 400
Canonsburg, Pennsylvania 15317

Members of the Board of Directors:

      Mylan Laboratories Inc. (“Mylan”), Summit Merger Corporation, a wholly owned subsidiary of Mylan (the “Merger Sub”), and King Pharmaceuticals, Inc. (“King”) propose to enter into an Agreement and Plan of Merger, dated as of July 23, 2004 (the “Agreement”), pursuant to which the Merger Sub will be merged with and into King in a transaction (the “Merger”) in which each outstanding share of King’s common stock, no par value (the “King Shares”), will be converted into the right to receive 0.9000 (the “Exchange Ratio”) of a share of the common stock of Mylan, par value $0.50 per share (the “Mylan Shares”).

      You have asked us whether, in our opinion, the Exchange Ratio is fair from a financial point of view to Mylan.

      In arriving at the opinion set forth below, we have, among other things:

        (1) Reviewed certain publicly available business and financial information relating to Mylan and King that we deemed to be relevant;
 
        (2) Reviewed certain information relating to the business, earnings, cash flow, assets, liabilities and prospects of Mylan and King, including financial forecasts relating to Mylan and King prepared by the management of Mylan, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the Merger (the “Expected Synergies”) furnished to us by Mylan;
 
        (3) Conducted discussions with members of senior managements of Mylan and King concerning the matters described in clauses 1 and 2 above, as well as their respective businesses and prospects before and after giving effect to the Merger and the Expected Synergies;
 
        (4) Reviewed the market prices and valuation multiples for the Mylan Shares and the King Shares and compared them with those of certain publicly traded companies that we deemed to be relevant;
 
        (5) Reviewed the results of operations of Mylan and King and compared them with those of certain publicly traded companies that we deemed to be relevant;
 
        (6) Compared the proposed financial terms of the Merger with the financial terms of certain other transactions that we deemed to be relevant;
 
        (7) Participated in certain discussions and negotiations among representatives of Mylan and King and their financial and legal advisors;

Page 2

        (8) Reviewed the relative contributions of Mylan and King to selected operational metrics of the combined company based on financial forecasts and estimates prepared by the management of Mylan;
 
        (9) Reviewed the potential pro forma impact of the Merger;
 
        (10) Reviewed the Agreement; and
 
        (11) Reviewed such other financial studies and analyses and took into account such other matters as we deemed necessary, including our assessment of general economic, market and monetary conditions.

      In preparing our opinion, we have assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to us, discussed with or reviewed by or for us, or publicly available, and we have not assumed any responsibility for independently verifying such information or undertaken an independent evaluation or appraisal of any of the assets or liabilities of Mylan or King or been furnished with any such evaluation or appraisal, nor have we evaluated the solvency or fair value of Mylan or King under any state or federal laws relating to bankruptcy, insolvency or similar matters. In addition, we have not assumed any obligation to conduct any physical inspection of the properties or facilities of Mylan or King. With respect to the financial forecast information and the Expected Synergies prepared by the management of Mylan and furnished to or discussed with us by Mylan, we have assumed that they have been reasonably prepared and reflect the best currently available estimates and judgment of Mylan’s management as to the expected future financial performance of Mylan or King, as the case may be, and the Expected Synergies. We have further assumed that the Merger will qualify as a reorganization for U.S. federal income tax purposes. In addition, we have assumed that each of Mylan, Merger Sub and King will comply with all material terms of the Agreement and that the Merger will be consummated in accordance with its terms without waiver, modification or amendment of any material term, condition or agreement.

      Our opinion is necessarily based upon market, economic and other conditions as they exist and can be evaluated on, and on the information made available to us as of, the date hereof. We have assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the Merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on Mylan, King or the contemplated benefits of the Merger.

      We are acting as financial advisor to Mylan in connection with the Merger and will receive a fee from Mylan for our services, a significant portion of which is contingent upon the consummation of the Merger. In addition, Mylan has agreed to indemnify us for certain liabilities arising out of our engagement. We have, in the past, provided financial advisory and financing services to King unrelated to the Merger and have received fees for the rendering of such services. In addition, in the ordinary course of our business, we may actively trade the King Shares and other securities of King, as well as the Mylan Shares and other securities of Mylan, for our own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

      This opinion is for the use and benefit of the Board of Directors of Mylan. Our opinion does not address the merits of the underlying decision by Mylan to engage in the Merger and does not constitute a recommendation to any shareholder of Mylan as to how such shareholder should vote on the proposed Merger or any matter related thereto. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Mylan. We are not expressing any opinion herein as to the prices at which the Mylan Shares or the King Shares will trade following the announcement of the Merger or the price at which the Mylan Shares will trade following the consummation of the Merger.

ANNEX C

OPINION OF GOLDMAN, SACHS & CO.

PERSONAL AND CONFIDENTIAL

July 23, 2004

Board of Directors

King Pharmaceuticals, Inc.
501 Fifth Street
Bristol, TN 37620

Madame and Gentlemen:

      You have requested our opinion as to the fairness from a financial point of view to the holders of the outstanding shares of common stock, no par value (the “Shares”), of King Pharmaceuticals, Inc. (the “Company”) of the exchange ratio of 0.900 shares of common stock, par value $0.50 per share (the “Mylan Common Stock”), of Mylan Laboratories Inc. (“Mylan”) to be received for each Share (the “Exchange Ratio”) pursuant to the Agreement and Plan of Merger, dated as of July 23, 2004 (the “Agreement”), by and among Mylan, Summit Merger Corporation, a wholly owned subsidiary of Mylan, and the Company.

      Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the “Transaction”). We expect to receive fees for our services in connection with the Transaction, all of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. In addition, we have provided certain investment banking services to the Company from time to time, including having acted (i) as its financial advisor in connection with its acquisition of Skelaxin® and Sonata®, pharmaceutical products, from Elan Corporation in June 2003, (ii) as its financial advisor in connection with its acquisition of the Ortho-Prefest® pharmaceutical product from Ortho-McNeil Pharmaceutical, Corp., a subsidiary of Johnson & Johnson, in May 2002, (iii) as co-lead manager of the private placement of $345,000,000 aggregate principal amount of the Company’s 2 3/4% Convertible Debentures due November 15, 2021 in November 2001, (iv) as a co-lead manager of a public offering of 22,492,000 of the Shares in November 2001, and (v) as agent in connection with repurchases by the Company of its Shares from time to time. We have also acted as agent for Mylan in connection with repurchases by Mylan of Mylan Common Stock from time to time. We also may provide investment banking services to the Company and Mylan in the future. In connection with the above-described investment banking services we have received, and may receive, compensation.

      Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, Mylan and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and Mylan for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

      In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company for the five fiscal years ended

C-1


Table of Contents

December 31, 2003 and for Mylan for the five fiscal years ended March 31, 2004; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and Mylan; certain other communications from the Company and Mylan to their respective stockholders; certain internal financial analyses and forecasts for the Company prepared by its management (the “Company Forecasts”); certain internal financial analyses and forecasts for Mylan prepared by its management, as adjusted for fiscal years after the fiscal year ending March 31, 2006 by management of the Company (the “Mylan Forecasts”); and certain cost and operational synergies estimated by the managements of Mylan and the Company to result from the Transaction (the “Synergies”). We also have held discussions with members of the senior managements of the Company and Mylan regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of their respective companies. In addition, we have reviewed the reported price and trading activity for the Shares and Mylan Common Stock, compared certain financial and stock market information for the Company and Mylan with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the specialty pharmaceuticals industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

      We have relied upon the accuracy and completeness of all of the financial, accounting and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the Company Forecasts and the Mylan Forecasts, including in each case the assumptions therein with respect to the expected financial impact of patent-related matters and other developments that could impact the pricing of, and demand for, the products of the Company and Mylan, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company and Mylan, as applicable, and that the Synergies reflect the best currently available estimates and judgments of the Company and Mylan. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or Mylan or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We also have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or Mylan or on the expected benefits of the Transaction in any way meaningful to our analysis. Our opinion does not address the underlying business decision of the Company to engage in the Transaction nor are we expressing any opinion as to the prices at which the Shares or the shares of Mylan Common Stock will trade at any time. With your consent, we have relied upon the advice the Company has received from its legal counsel and accounting and tax advisors as to all legal matters, including intellectual property and regulatory matters, and accounting and tax matters in connection with the Transaction.

      Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Shares should vote with respect to the Transaction.

      Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair from a financial point of view to the holders of Shares.

Very truly yours,  
 
/s/ GOLDMAN, SACHS & CO.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS; UNDERTAKINGS

 
Item 20. Indemnification of Directors and Officers

      The following summary is qualified in its entirety by reference to the complete copy of the Pennsylvania General Corporation Law and Mylan’s Amended and Restated Certificate of Incorporation, as amended through August 7, 2003.

      Sections 1741 and 1742 of the Pennsylvania Business Corporation Law of 1988, as amended (the “PBCL”), provide that a business corporation may indemnify directors and officers against liabilities they may incur as such provided that the particular person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of actions against a director or officer by or in the right of the corporation, the power to indemnify extends only to expenses (not judgments and amounts paid in settlement) and such power generally does not exist if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for specified expenses. Under Section 1743 of the PBCL, the corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such capacities if they are successful on the merits or otherwise in the defense of such actions. Under Section 1745 of the PBCL, a corporation may pay the expenses of a director or officer incurred in defending an action or proceeding in advance of the final disposition thereof upon receipt of an undertaking from such person to repay the amounts advanced unless it is ultimately determined that such person is entitled to indemnification from the corporation.

      Section 1746 of the PBCL grants a corporation broad authority to indemnify its directors, officers and other agents for liabilities and expenses incurred in such capacity, except in circumstances where the act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. Pursuant to the authority of Section 1746 of the PBCL, Mylan has also entered into employment agreements with certain principal officers which also provide for indemnification in connection with the performance of their offices.

      In accordance with the PBCL, Mylan’s bylaws provide that a director of Mylan shall not be personally liable for monetary damages for any action taken, or any failure to take any action, unless the director has breached or failed to perform the duties required under applicable provisions of the PBCL and the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness; provided, however, that this limitation of liability does not apply to the responsibility or liability of a director pursuant to any criminal stature or the liability of a director for payment of certain taxes.

      As permitted by the PBCL, Mylan’s bylaws provide that Mylan shall indemnify and hold harmless, to the fullest extent authorized by law (including, but not limited to, the PBCL), any person made or threatened to be made a party to, or otherwise involved in, any legal action by reason of the fact that such person is or was a director, officer, employee or other corporate agent of Mylan or served any other enterprise at the request of Mylan, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such person in connection with such action; provided, however, that Mylan shall indemnify any such person only if such proceeding was authorized by the Mylan board of directors.

      The directors and officers of Mylan are insured under a policy of directors’ and officers’ liability insurance.

Item 22. Undertakings

      (a) The undersigned registrant hereby undertakes:

        (i) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

        (A) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933.
 
        (B) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.
 
        (C) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

        (ii) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-2


Table of Contents

        (iii) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.
 
        (iv) That every prospectus (1) that is filed pursuant to paragraph (i) immediately preceding, or (2) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
        (v) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
        (vi) To respond to requests for information that is incorporated by reference into the joint proxy statement/ prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
 
        (vii) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

      (b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
