6.25% Convertible Perpetual Preferred Stock

(Liquidation Preference $100 per Share)

 

 

 

 

We are offering 3,000,000 shares of our 6.25% convertible perpetual preferred stock. The annual dividend on each share of convertible preferred stock is $6.25 and is payable, when, as and if declared by our board of directors, quarterly in cash, common stock or a combination thereof at our election, in arrears, on each March 15, June 15, September 15 and December 15, commencing on September 15, 2009. Each share of convertible preferred stock has a liquidation preference of $100 per share and is convertible, at the holder’s option at any time, initially into 2.3033 shares of our common stock based on an initial conversion price of $43.4163 per share, subject in each case to specified adjustments as set forth in this prospectus supplement. The convertible preferred stock is not redeemable by us at any time. If a fundamental change occurs, we may be required to pay a make-whole premium on convertible preferred stock converted in connection therewith, as described in this prospectus supplement. On or after June 15, 2013, we may at our option cause all outstanding shares of the convertible preferred stock to be automatically converted into that number of shares of common stock for each share of convertible preferred stock equal to $100 divided by the then-prevailing conversion price if the closing price of our common stock equals or exceeds 120% of the then-prevailing conversion price for at least 20 trading days in a period of 30 consecutive trading days.

 

Our convertible preferred stock has been approved for listing on the New York Stock Exchange under the symbol “WLL PrA”, subject to official notice of issuance. Our common stock is traded on the New York Stock Exchange under the symbol “WLL.” On June 17, 2009, the last sale price of our common stock as reported on the New York Stock Exchange was $36.95 per share.

 

Investing in our convertible preferred stock involves risks that are described in the “Risk Factors” section beginning on page S-14 of this prospectus supplement.

 

 

 

 

 

(1) Plus accrued dividends, if any, from June 23, 2009

 

The underwriters may also purchase up to an additional 450,000 shares from us at the public offering price, less the underwriting discount, within 30 days from the date of this prospectus supplement to cover overallotments.

 

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

 

The shares will be ready for delivery in book entry form through the facilities of the Depository Trust Company only, on or about June 23, 2009.

Prospectus

 

 

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering. The second part, the accompanying prospectus, gives more general information, some of which may not apply to this offering. You should read the entire prospectus supplement, as well as the accompanying prospectus and the documents incorporated by reference that are described under “Where You Can Find More Information” in this prospectus supplement and the accompanying prospectus. In the event that the description of this offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information contained in this prospectus supplement.

 

You should rely only on the information contained in this prospectus supplement and the accompanying prospectus. We have not, and the underwriters have not, authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. You should assume that the information appearing in this prospectus supplement and the accompanying prospectus is accurate only as of the date on their respective front covers. Our business, financial condition, results of operations and prospects may have changed since those dates.

 

In this prospectus supplement, except as otherwise noted, “we,” “us,” “our” or “ours” refer to Whiting Petroleum Corporation and its consolidated subsidiaries.

 

We have included below the definitions for certain oil and gas terms used in this prospectus supplement:

 

“3-D seismic” Geophysical data that depict the subsurface strata in three dimensions. 3-D seismic typically provides a more detailed and accurate interpretation of the subsurface strata than 2-D, or two-dimensional, seismic.

 

“Bbl” One stock tank barrel, or 42 U.S. gallons liquid volume, used in this prospectus supplement in reference to oil and other liquid hydrocarbons.

 

“Bcf” One billion cubic feet of natural gas.

 

“BOE” One stock tank barrel equivalent of oil, calculated by converting natural gas volumes to equivalent oil barrels at a ratio of six Mcf to one Bbl of oil.

 

“BOE/d” One BOE per day.

 

“CO₂ flood” A tertiary recovery method in which CO₂ is injected into a reservoir to enhance oil recovery.

 

“completion” The installation of permanent equipment for the production of oil or natural gas, or in the case of a dry hole, the reporting of abandonment to the appropriate agency.

 

“GAAP” Generally accepted accounting principles in the United States of America.

 

“MBOE” One thousand BOE.

 

“MBOE/d” One MBOE per day.

 

“Mcf” One thousand cubic feet of natural gas.

 

“MMBbl” One million Bbl.

 

“MMBOE” One million BOE.

 

“MMBtu” One million British Thermal Units.

 

“MMcf” One million cubic feet of natural gas.

 

“MMcf/d” One MMcf per day.

“net revenue interest” The interest owned in the revenues of a crude oil and natural gas property, after all royalties and other burdens have been deducted from the working interest.

 

“plugging and abandonment” Refers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum will not escape into another or to the surface. Regulations of many states require plugging of abandoned wells.

 

“pre-tax PV10%” The present value of estimated future revenues to be generated from the production of proved reserves calculated in accordance with the Securities and Exchange Commission (“SEC”) guidelines, net of estimated lease operating expense, production taxes and future development costs, using price and costs as of the date of estimation without future escalation, without giving effect to non-property related expenses such as general and administrative expenses, debt service and depreciation, depletion and amortization, or Federal income taxes and discounted using an annual discount rate of 10%.

 

“reservoir” A porous and permeable underground formation containing a natural accumulation of producible oil and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs.

 

“resource play” Refers to drilling programs targeted at regionally distributed oil or natural gas accumulations. Successful exploitation of these reservoirs is dependent upon new technologies such as horizontal drilling and multi-stage fracture stimulation to access large rock volumes in order to produce economic quantities of oil or natural gas.

 

“working interest” The interest in a crude oil and natural gas property (normally a leasehold interest) that gives the owner the right to drill, produce and conduct operations on the property and a share of production, subject to all royalties, overriding royalties and other burdens and to all costs of exploration, development and operations and all risks in connection therewith.

(1)		Oil includes natural gas liquids.
(2)		Pre-tax PV10% is a non-GAAP financial measure as defined by the SEC and is derived from the standardized measure of discounted future net cash flows, which is the most directly comparable GAAP financial measure. Pre-tax PV10% is computed on the same basis as the standardized measure of discounted future net cash flows, but without deducting future income taxes. As of December 31, 2008, our discounted future income taxes were $226.6 million and our standardized measure of discounted future net cash flows was $1,376.4 million. We believe pre-tax PV10% is a useful measure to investors in evaluating the relative monetary significance of our oil and gas properties. We further believe investors may utilize our pre-tax PV10% as a basis for comparison of the relative size and value of our reserves to other companies because many factors that are unique to each individual company impact the amount of future income taxes to be paid. Our management uses this measure when assessing the potential return on investment related to our oil and gas properties and acquisitions. However, pre-tax PV10% is not a substitute for the standardized measure of discounted future net cash flows. Our pre-tax PV10% and the standardized measure of discounted future net cash flows do not purport to present the fair value of our oil and natural gas reserves.

(2)		2009 planned capital expenditures at our CO2 projects include $36.9 million for purchased CO2 at North Ward Estes and $15.3 million for Postle CO2 purchases.
(3)		Comprised primarily of exploration salaries, lease delay rentals and seismic, development in other regions and drilling rig early termination fees.

Securities Offered		3,000,000 shares of 6.25% convertible perpetual preferred stock; 3,450,000 shares if the underwriters exercise their option to purchase additional convertible preferred stock to cover overallotments in full.

Liquidation Preference		$100 per share, plus accumulated and unpaid dividends.

Dividends		Cumulative annual dividends of $6.25 per share payable quarterly on each March 15, June 15, September 15 and December 15, commencing on September 15, 2009, when, as and if declared by the board of directors. Dividends will accumulate and be paid in arrears on the basis of a 360-day year consisting of twelve 30-day months. Dividends on the convertible preferred stock will accumulate and be cumulative from the most recent date to which dividends have been paid, or if no dividends have been paid, from June 23, 2009 and may be paid in cash or, where freely transferable by any non-affiliate recipient thereof, in common stock or a combination thereof. Accumulated dividends on the convertible preferred stock will not bear interest. See “Description of Preferred Stock — Dividends.”

		If we elect to make any such payment, or any portion thereof, in shares of our common stock, such shares shall be valued for such purpose, in the case of any dividend payment, or portion thereof, at 97% of the average of the volume-weighted average prices of our common stock for the ten days preceding the second trading day immediately prior to the record date for such dividend.
		We will make each dividend payment on the convertible preferred stock in cash, except to the extent we elect to make all or any portion of such payment in shares of our common stock. We will give the holders of the convertible preferred stock notice of any such election and the portion of such payment that will be made in cash and the portion that will be made in common stock 15 business days prior to the record date for such dividend. See “Risk Factors — Risks Relating to the convertible preferred stock — We may not be able to pay dividends on the convertible preferred stock and no payment or adjustment will be made upon conversion for accumulated dividends.”
Ranking		The convertible preferred stock will rank with respect to dividend rights and rights upon our liquidation, winding-up or dissolution:
		•      senior to all of our common stock, our Series A Junior Participating Preferred Stock and all of our other capital stock issued in the future, unless the terms of that stock expressly provide that it ranks senior to, or on a parity with, the convertible preferred stock;

		•      on a parity with any of our capital stock issued in the future, the terms of which expressly provide that it will rank on a parity with the convertible preferred stock; and
		•      junior to all of our capital stock issued in the future, the terms of which expressly provide that such stock will rank senior to the convertible preferred stock.
		We currently have no outstanding shares of preferred stock, but have designated 1,500,000 shares of preferred stock as Series A Junior Participating Preferred Stock, which may be issued upon the exercise of our preferred share purchase rights.
Redemption		The convertible preferred stock will not be redeemable by us.

Conversion Rights		Each share of convertible preferred stock will be convertible, at any time, at the option of the holder thereof into a number of shares of our common stock equal to $100 divided by the conversion price at the time of conversion. The initial conversion price is $43.4163, and is subject to adjustment as described under “Description of Preferred Stock — Conversion Price Adjustment.” Based on the initial conversion price, each share of convertible preferred stock is convertible into 2.3033 shares of our common stock.

Mandatory Conversion		At any time on or after June 15, 2013, we may at our option cause all outstanding shares of the convertible preferred stock to be automatically converted into that number of shares of common stock for each share of convertible preferred stock equal to $100 divided by the then-prevailing conversion price if the closing price of our common stock equals or exceeds 120% of the then-prevailing conversion price for at least 20 trading days in a period of 30 consecutive trading days, including the last trading day of such 30-day period, ending on the trading day prior to our issuance of a press release announcing the mandatory conversion as described under “Description of Preferred Stock — Mandatory Conversion.”
Fundamental Change		If a holder converts its convertible preferred stock at any time beginning at the opening of business on the trading day immediately following the effective date of a fundamental change (as described under “Description of Preferred Stock — Special Rights Upon a Fundamental Change”) and ending at the close of business on the 30th trading day immediately following such effective date, the holder will automatically receive a number of shares of our common stock equal to the greater of:
		•      the sum of (i) a number of shares of our common stock, as described under “Description of Preferred Stock — Conversion Rights” and subject to adjustment as described under “Description of Preferred Stock — Conversion Price Adjustment” and (ii) the make-whole premium, if any, described under “Description of Preferred Stock — Determination of the Make-Whole Premium”; and
		•      a number of shares of our common stock calculated by reference to an adjusted conversion price equal to the greater of (i) the average of the volume-weighted average prices of

		our common stock for ten days preceding the effective date of a fundamental change and (ii) $24.63.

Voting Rights		Except as required by Delaware law and our certificate of incorporation, which will include the certificate of designation for the convertible preferred stock, the holders of convertible preferred stock will have no voting rights unless dividends payable on the convertible preferred stock are in arrears for six or more quarterly periods. In that event, the holders of the convertible preferred stock, voting as a single class with the shares of any other preferred stock or preference securities having similar voting rights, will be entitled at the next regular or special meeting of our stockholders to elect two directors and the number of directors that comprise our board will be increased by the number of directors so elected. These voting rights and the terms of the directors so elected will continue until such time as the dividend arrearage on the convertible preferred stock has been paid in full. The affirmative vote or consent of holders of at least 662/3% of the outstanding convertible preferred stock will be required for the issuance of any class or series of stock (or security convertible into stock) ranking senior to the convertible preferred stock as to dividend rights or rights upon our liquidation, winding-up or dissolution and for amendments to our certificate of incorporation by merger or otherwise that would affect adversely the rights of holders of the convertible preferred stock.
Use of Proceeds		We expect to use the net proceeds from this offering to repay a portion of the debt outstanding under our credit agreement. The amounts repaid under the credit agreement will be available for us to reborrow in the future. See “Use of Proceeds.” Affiliates of certain of the underwriters are lenders under our credit facility, and accordingly, will receive a substantial portion of the proceeds from this offering in the form of the repayment of borrowings under such facility. See “Underwriting.”
Tax Consequences		The U.S. federal income tax consequences of purchasing, owning and disposing of the convertible preferred stock and any common stock received as a dividend or upon its conversion are described in “Certain U.S. Federal Income Tax Considerations.” Prospective investors are urged to consult their own tax advisors regarding these matters in light of their personal investment circumstances, including consequences resulting from the possibility that actual or constructive distributions on the convertible preferred stock may exceed our current and accumulated earnings and profits, as calculated for U.S. federal income tax purposes, in which case such distributions would not be treated as dividends for U.S. federal income tax purposes.
Absence of a Public Market		Our convertible preferred stock has been approved for listing on the New York Stock Exchange under the symbol “WLL PrA”, subject to official notice of issuance. However, the convertible preferred stock is a new security for which there is currently no public market. If an active public market does not develop, the market price and liquidity of the convertible preferred stock will be adversely affected.

Book Entry, Delivery and Form		Initially, the convertible preferred stock will be represented by one or more permanent global certificates in definitive, fully registered form deposited with a custodian for, and registered in the name of, a nominee of the Depository Trust Company.
Risk Factors		Please read “Risk Factors” and the other information in this prospectus supplement and the accompanying prospectus for a discussion of factors you should carefully consider before deciding to invest in shares of our convertible preferred stock.
Common Stock		Our common stock is listed for trading on the New York Stock Exchange under the symbol “WLL.”

(1)		We define EBITDA as earnings before interest, taxes, depreciation, depletion and amortization. EBITDA is not a measure of performance calculated in accordance with GAAP. Although not prescribed under GAAP, we believe the presentation of EBITDA is relevant and useful because it helps our investors to understand our operating performance and makes it easier to compare our results with other companies that have different financing and capital structures or tax rates. EBITDA should not be considered in isolation of, or as a substitute for, net income as an indicator of operating performance or cash flows from operating activities as a measure of liquidity. EBITDA, as we calculate it, may not be comparable to EBITDA measures reported by other companies. In addition, EBITDA does not represent funds available for discretionary use.
		The following table presents a reconciliation of our consolidated net income to our consolidated EBITDA for the periods presented:

(3)		The standardized measure of discounted future net cash flows, which reflects the after-tax present value of discounted future net cash flows, relating to proved oil and natural gas reserves were prepared in accordance with the provisions of Statement of Financial Accounting Standards No. 69, Disclosures about Oil and Gas Producing Activities. Future cash inflows were computed by applying prices at year end to estimated future production. Future production and development costs are computed by estimating the expenditures to be incurred in developing and producing the proved oil and natural gas reserves at year end, based on year-end costs and assuming continuation of existing economic conditions. Future net cash flows are discounted at a rate of 10% annually to derive the standardized measure of discounted future net cash

		flows. This calculation procedure does not necessarily result in an estimate of the fair market value or the present value of our oil and gas properties.

You should carefully consider each of the risks described below, together with all of the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, before deciding to invest in shares of our convertible preferred stock. If any of the following risks develop into actual events, our business, financial condition or results of operations could be materially adversely affected and you may lose all or part of your investment.

 

Risks Relating to the Oil and Gas Industry and Our Business

 

Oil and natural gas prices are very volatile. An extended period of low oil and natural gas prices may adversely affect our business, financial condition, results of operations or cash flows.

 

The oil and gas markets are very volatile, and we cannot predict future oil and natural gas prices. The price we receive for our oil and natural gas production heavily influences our revenue, profitability, access to capital and future rate of growth. The prices we receive for our production and the levels of our production depend on numerous factors beyond our control. These factors include, but are not limited to, the following:

 

 

Furthermore, the recent worldwide financial and credit crisis has reduced the availability of liquidity and credit to fund the continuation and expansion of industrial business operations worldwide. The shortage of liquidity and credit combined with recent substantial losses in worldwide equity markets has led to a worldwide economic recession. The slowdown in economic activity caused by such recession has reduced worldwide demand for energy and resulted in lower oil and natural gas prices. Oil and natural gas prices have fallen significantly since their third quarter 2008 levels. For example, the daily average NYMEX oil price was $118.13 per Bbl for the third quarter of 2008, $58.75 per Bbl for the fourth quarter of 2008, and $43.21 per Bbl for the first quarter of 2009. Similarly, daily average NYMEX natural gas prices have declined from $10.27 per Mcf for the third quarter of 2008 to $6.96 per Mcf for the fourth quarter of 2008 and $4.92 for the first quarter of 2009.

 

Lower oil and natural gas prices may not only decrease our revenues on a per unit basis but also may reduce the amount of oil and natural gas that we can produce economically and therefore potentially lower our reserve bookings. A substantial or extended decline in oil or natural gas prices may result in impairments of our proved oil and gas properties and may materially and adversely affect our future business, financial condition, results of operations, liquidity or ability to finance planned capital expenditures. To the extent commodity prices received from production are insufficient to fund planned capital expenditures, we will be required to reduce spending or borrow any such shortfall. Lower oil and natural gas prices may also reduce

the amount of our borrowing base under our credit agreement, which is determined at the discretion of the lenders based on the collateral value of our proved reserves that have been mortgaged to the lenders, and is subject to regular redeterminations on May 1 and November 1 of each year, as well as special redeterminations described in the credit agreement.

 

The global financial crisis and recession may have impacts on our business and financial condition that we currently cannot predict.

 

The continued turmoil in the global financial system and the current global recession may have an impact on our business and our financial condition, and we may face challenges if conditions in the financial markets do not improve. Our ability to access the capital markets may be restricted at a time when we would like, or need, to raise financing, which could have an impact on our flexibility to react to changing economic and business conditions. The economic situation could have an impact on our lenders or customers, causing them to fail to meet their obligations to us. Additionally, market conditions could have an impact on our commodity hedging arrangements if our counterparties are unable to perform their obligations or seek bankruptcy protection.

 

Drilling for and producing oil and natural gas are high risk activities with many uncertainties that could adversely affect our business, financial condition or results of operations.

 

Our future success will depend on the success of our development, exploitation, production and exploration activities. Our oil and natural gas exploration and production activities are subject to numerous risks beyond our control, including the risk that drilling will not result in commercially viable oil or natural gas production. Our decisions to purchase, explore, develop or otherwise exploit prospects or properties will depend in part on the evaluation of data obtained through geophysical and geological analyses, production data and engineering studies, the results of which are often inconclusive or subject to varying interpretations. Please read “— Reserve estimates depend on many assumptions that may turn out to be inaccurate . . .” later in these Risk Factors for a discussion of the uncertainty involved in these processes. Our cost of drilling, completing and operating wells is often uncertain before drilling commences. Overruns in budgeted expenditures are common risks that can make a particular project uneconomical. Further, many factors may curtail, delay or cancel drilling, including the following:

 

 

Prospects that we decide to drill may not yield oil or gas in commercially viable quantities.

 

We describe some of our current prospects and our plans to explore those prospects in this prospectus supplement and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2009 and Annual Report on Form 10-K for the year ended December 31, 2008, which are incorporated by reference in this prospectus supplement and the accompanying prospectus. A prospect is a property on which we have identified what our geoscientists believe, based on available seismic and geological information, to be indications of oil or gas. Our prospects are in various stages of evaluation, ranging from a prospect which is ready to drill to a prospect that will require substantial additional seismic data processing and interpretation. There is no way to predict in advance of drilling and testing whether any particular prospect will yield oil or gas in sufficient quantities to recover drilling or completion costs or to be economically viable. The use of seismic data and other technologies and the study of producing fields in the same area will not enable us to know conclusively prior to drilling whether oil or gas will be present or, if present, whether oil or gas will be present in

commercial quantities. In addition, because of the wide variance that results from different equipment used to test the wells, initial flowrates may not be indicative of sufficient oil or gas quantities in a particular field. The analogies we draw from available data from other wells, from more fully explored prospects, or from producing fields may not be applicable to our drilling prospects. We may terminate our drilling program for a prospect if results do not merit further investment.

 

Our identified drilling locations are scheduled out over several years, making them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling.

 

We have specifically identified and scheduled drilling locations as an estimation of our future multi-year drilling activities on our existing acreage. As of December 31, 2008, we had identified a drilling inventory of over 1,400 gross drilling locations. These scheduled drilling locations represent a significant part of our growth strategy. Our ability to drill and develop these locations depends on a number of uncertainties, including oil and natural gas prices, the availability of capital, costs of oil field goods and services, drilling results, regulatory approvals and other factors. Because of these uncertainties, we do not know if the numerous potential drilling locations we have identified will ever be drilled or if we will be able to produce oil or gas from these or any other potential drilling locations. As such, our actual drilling activities may materially differ from those presently identified, which could adversely affect our business.

 

We have been an early entrant into new or emerging plays. As a result, our drilling results in these areas are uncertain, and the value of our undeveloped acreage will decline and we may incur impairment charges if drilling results are unsuccessful.

 

While our costs to acquire undeveloped acreage in new or emerging plays have generally been less than those of later entrants into a developing play, our drilling results in these areas are more uncertain than drilling results in areas that are developed and producing. Since new or emerging plays have limited or no production history, we are unable to use past drilling results in those areas to help predict our future drilling results. Therefore, our cost of drilling, completing and operating wells in these areas may be higher than initially expected, and the value of our undeveloped acreage will decline if drilling results are unsuccessful. Furthermore, if drilling results are unsuccessful, we may be required to write down the carrying value of our undeveloped acreage in new or emerging plays. For example, during the fourth quarter of 2008, we recorded a $10.9 million non-cash charge for the partial impairment of unproved properties in the central Utah Hingeline play. We may also incur such impairment charges in the future, which could have a material adverse effect on our results of operations in the period taken. Additionally, our rights to develop a portion of our undeveloped acreage may expire if not successfully developed or renewed. Out of a total of 892,130 gross (420,776 net) undeveloped acreage as of December 31, 2008, the portion that is subject to expiration over the next three years, if not successfully developed or renewed, is approximately 17% in 2009, 16% in 2010, and 16% in 2011.

 

Our use of enhanced recovery methods creates uncertainties that could adversely affect our results of operations and financial condition.

 

One of our business strategies is to commercially develop oil reservoirs using enhanced recovery technologies. For example, we inject water and CO₂ into formations on some of our properties to increase the production of oil and natural gas. The additional production and reserves attributable to the use of these enhanced recovery methods are inherently difficult to predict. If our enhanced recovery programs do not allow for the extraction of oil and gas in the manner or to the extent that we anticipate, our future results of operations and financial condition could be materially adversely affected. Additionally, our ability to utilize CO₂ as an enhanced recovery technique is subject to our ability to obtain sufficient quantities of CO₂. Under our CO₂ contracts, if the supplier suffers an inability to deliver its contractually required quantities of CO₂ to us and other parties with whom it has CO₂ contracts, then the supplier may reduce the amount of CO₂ on a pro rata basis it provides to us and such other parties. If this occurs, we may not have sufficient CO₂ to produce oil and natural gas in the manner or to the extent that we anticipate. These contracts are also structured as “take-or-pay” arrangements, which require us to continue to make payments even if we decide to terminate or reduce our use of CO₂ as part of our enhanced recovery techniques.

The development of the proved undeveloped reserves in the North Ward Estes and Postle fields may take longer and may require higher levels of capital expenditures than we currently anticipate.

 

As of December 31, 2008, undeveloped reserves comprised 46.5% of the North Ward Estes field’s total estimated proved reserves and 16.8% of the Postle field’s total estimated proved reserves. To fully develop these reserves, we expect to incur future development costs of $410.1 million at the North Ward Estes field and $84.5 million at the Postle field as of December 31, 2008. Together, these fields encompass 58% of our total estimated future development costs of $857.1 million related to proved undeveloped reserves. Development of these reserves may take longer and require higher levels of capital expenditures than we currently anticipate. In addition, the development of these reserves will require the use of enhanced recovery techniques, including water flood and CO₂ injection installations, the success of which is less predictable than traditional development techniques. Therefore, ultimate recoveries from these fields may not match current expectations.

 

If oil and natural gas prices decrease, we may be required to take write-downs of the carrying values of our oil and gas properties.

 

Accounting rules require that we review periodically the carrying value of our oil and gas properties for possible impairment. Based on specific market factors and circumstances at the time of prospective impairment reviews, which may include depressed oil and natural gas prices, and the continuing evaluation of development plans, production data, economics and other factors, we may be required to write down the carrying value of our oil and gas properties. A write-down constitutes a non-cash charge to earnings. We may incur impairment charges in the future, which could have a material adverse effect on our results of operations in the period taken.

 

Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.

 

The process of estimating oil and natural gas reserves is complex. It requires interpretations of available technical data and many assumptions, including assumptions relating to economic factors. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves referred to in this prospectus supplement.

 

In order to prepare our estimates, we must project production rates and timing of development expenditures. We must also analyze available geological, geophysical, production and engineering data. The extent, quality and reliability of this data can vary. The process also requires economic assumptions about matters such as oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. Therefore, estimates of oil and natural gas reserves are inherently imprecise.

 

Actual future production, oil and natural gas prices, revenues, taxes, exploration and development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves most likely will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of reserves referred to in this prospectus supplement. In addition, we may adjust estimates of proved reserves to reflect production history, results of exploration and development, prevailing oil and natural gas prices and other factors, many of which are beyond our control.

 

You should not assume that the present value of future net revenues from our proved reserves, as referred to in this prospectus supplement, is the current market value of our estimated oil and natural gas reserves. In accordance with SEC requirements, we generally base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the present value estimate. If natural gas prices decline by $0.10 per Mcf, then the standardized measure of discounted future net cash flows of our estimated proved reserves as of December 31, 2008 would have decreased from $1,376.4 million to $1,366.0 million. If oil prices decline by $1.00 per Bbl, then the standardized measure of discounted future net cash flows of our estimated proved reserves as of December 31, 2008 would have decreased from $1,376.4 million to $1,326.1 million.

Our debt level and the covenants in the agreements governing our debt could negatively impact our financial condition, results of operations, cash flows and business prospects.

 

As of May 31, 2009, we had $670.0 million in borrowings and $2.8 million in letters of credit outstanding under Whiting Oil and Gas Corporation’s credit agreement with $427.2 million of available borrowing capacity, as well as $620.0 million of senior subordinated notes outstanding. We are permitted to incur additional indebtedness, provided we meet certain requirements in the indentures governing our senior subordinated notes and Whiting Oil and Gas Corporation’s credit agreement.

 

Our level of indebtedness and the covenants contained in the agreements governing our debt could have important consequences for our operations, including:

 

 

We may be required to repay all or a portion of our debt on an accelerated basis in certain circumstances. If we fail to comply with the covenants and other restrictions in the agreements governing our debt, it could lead to an event of default and the acceleration of our repayment of outstanding debt. In addition, if we are in default under the agreements governing our indebtedness, we will not be able to pay dividends on our convertible preferred stock. Our ability to comply with these covenants and other restrictions may be affected by events beyond our control, including prevailing economic and financial conditions. Moreover, the borrowing base limitation on Whiting Oil and Gas Corporation’s credit agreement is periodically redetermined based on an evaluation of our reserves. Upon a redetermination, if borrowings in excess of the revised borrowing capacity were outstanding, we could be forced to repay a portion of our debt under the credit agreement.

 

We may not have sufficient funds to make such repayments. If we are unable to repay our debt out of cash on hand, we could attempt to refinance such debt, sell assets or repay such debt with the proceeds from an equity offering. We may not be able to generate sufficient cash flow to pay the interest on our debt or future borrowings, and equity financings or proceeds from the sale of assets may not be available to pay or refinance such debt. The terms of our debt, including Whiting Oil and Gas Corporation’s credit agreement, may also prohibit us from taking such actions. Factors that will affect our ability to raise cash through an offering of our capital stock, a refinancing of our debt or a sale of assets include financial market conditions and our market value and operating performance at the time of such offering or other financing. We may not be able to successfully complete any such offering, refinancing or sale of assets.

 

The instruments governing our indebtedness contain various covenants limiting the discretion of our management in operating our business.

 

The indentures governing our senior subordinated notes and Whiting Oil and Gas Corporation’s credit agreement contain various restrictive covenants that may limit our management’s discretion in certain respects. In particular, these agreements will limit our and our subsidiaries’ ability to, among other things:

 

 

In addition, Whiting Oil and Gas Corporation’s credit agreement requires us, as of the last day of any quarter, (i) to not exceed a total debt to EBITDAX ratio (as defined in the credit agreement) for the last four quarters of 4.5 to 1.0 for quarters ending prior to and on September 30, 2010, 4.25 to 1.0 for quarters ending December 31, 2010 to June 30, 2011 and 4.0 to 1.0 for quarters ending September 30, 2011 and thereafter, (ii) to have a consolidated current assets to consolidated current liabilities ratio (as defined in the credit agreement) of not less than 1.0 to 1.0 and (iii) to not exceed a senior secured debt to EBITDAX ratio (as defined in the credit agreement) for the last four quarters of 2.75 to 1.0 for quarters ending prior to and on December 31, 2009 and 2.5 to 1.0 for quarters ending March 31, 2010 and thereafter. Also, the indentures under which we issued our senior subordinated notes restrict us from incurring additional indebtedness, subject to certain exceptions, unless our fixed charge coverage ratio (as defined in the indentures) is at least 2.0 to 1. If we were in violation of this covenant, then we may not be able to incur additional indebtedness, including under Whiting Oil and Gas Corporation’s credit agreement. A substantial or extended decline in oil or natural gas prices may adversely affect our ability to comply with these covenants.

 

If we fail to comply with the restrictions in the indentures governing our senior subordinated notes or Whiting Oil and Gas Corporation’s credit agreement or any other subsequent financing agreements, a default may allow the creditors, if the agreements so provide, to accelerate the related indebtedness as well as any other indebtedness to which a cross-acceleration or cross-default provision applies. In addition, lenders may be able to terminate any commitments they had made to make available further funds. Furthermore, if we are in default under the agreements governing our indebtedness, we will not be able to pay dividends on our convertible preferred stock.

 

Our exploration and development operations require substantial capital, and we may be unable to obtain needed capital or financing on satisfactory terms, which could lead to a loss of properties and a decline in our oil and natural gas reserves.

 

The oil and gas industry is capital intensive. We make and expect to continue to make substantial capital expenditures in our business and operations for the exploration, development, production and acquisition of oil and natural gas reserves. To date, we have financed capital expenditures through a combination of equity and debt issuances, bank borrowings and internally generated cash flows. We intend to finance future capital expenditures with cash flow from operations and existing financing arrangements. Our cash flow from operations and access to capital is subject to a number of variables, including:

 

 

If our revenues or the borrowing base under our bank credit agreement decreases as a result of lower oil and natural gas prices, operating difficulties, declines in reserves or for any other reason, then we may have limited ability to obtain the capital necessary to sustain our operations at current levels. We may, from time to time, need to seek additional financing. There can be no assurance as to the availability or terms of any additional financing.

 

If additional capital is needed, we may not be able to obtain debt or equity financing on terms favorable to us, or at all. If cash generated by operations or available under our revolving credit facility is not sufficient to meet our capital requirements, the failure to obtain additional financing could result in a curtailment of our operations relating to the exploration and development of our prospects, which in turn could lead to a possible loss of properties and a decline in our oil and natural gas reserves.

 

Our acquisition activities may not be successful.

 

As part of our growth strategy, we have made and may continue to make acquisitions of businesses and properties. However, suitable acquisition candidates may not continue to be available on terms and conditions we find acceptable, and acquisitions pose substantial risks to our business, financial condition and results of operations. In pursuing acquisitions, we compete with other companies, many of which have greater financial and other resources to acquire attractive companies and properties. The following are some of the risks associated with acquisitions, including any completed or future acquisitions:

 

 

Substantial acquisitions or other transactions could require significant external capital and could change our risk and property profile.

 

In order to finance acquisitions of additional producing or undeveloped properties, we may need to alter or increase our capitalization substantially through the issuance of debt or equity securities, the sale of production payments or other means. These changes in capitalization may significantly affect our risk profile. Additionally, significant acquisitions or other transactions can change the character of our operations and business. The character of the new properties may be substantially different in operating or geological characteristics or geographic location than our existing properties. Furthermore, we may not be able to obtain external funding for future acquisitions or other transactions or to obtain external funding on terms acceptable to us.

 

Properties that we acquire may not produce as projected, and we may be unable to identify liabilities associated with the properties or obtain protection from sellers against them.

 

Our business strategy includes a continuing acquisition program. From 2004 through 2008, we completed 13 separate acquisitions of producing properties with a combined purchase price of $1,823.8 million for estimated proved reserves as of the effective dates of the acquisitions of 226.9 MMBOE. The successful acquisition of producing properties requires assessments of many factors, which are inherently inexact and may be inaccurate, including the following:

 

 

Our assessment will not reveal all existing or potential problems, nor will it permit us to become familiar enough with the properties to assess fully their capabilities and deficiencies. In the course of our due diligence, we may not inspect every well, platform or pipeline. Inspections may not reveal structural and environmental problems, such as pipeline corrosion or groundwater contamination, when they are made. We may not be able to obtain contractual indemnities from the seller for liabilities that it created. We may be required to assume the risk of the physical condition of the properties in addition to the risk that the properties may not perform in accordance with our expectations.

 

Seasonal weather conditions and lease stipulations adversely affect our ability to conduct drilling activities in some of the areas where we operate.

 

Oil and gas operations in the Rocky Mountains are adversely affected by seasonal weather conditions and lease stipulations designed to protect various wildlife. In certain areas, drilling and other oil and gas activities can only be conducted during the spring and summer months. This limits our ability to operate in those areas and can intensify competition during those months for drilling rigs, oil field equipment, services, supplies and qualified personnel, which may lead to periodic shortages. Resulting shortages or high costs could delay our operations and materially increase our operating and capital costs.

 

The differential between the NYMEX or other benchmark price of oil and natural gas and the wellhead price we receive could have a material adverse effect on our results of operations, financial condition and cash flows.

 

The prices that we receive for our oil and natural gas production generally trade at a discount to the relevant benchmark prices such as NYMEX. The difference between the benchmark price and the price we receive is called a differential. We cannot accurately predict oil and natural gas differentials. Increases in the differential between the benchmark price for oil and natural gas and the wellhead price we receive could have a material adverse effect on our results of operations, financial condition and cash flows.

 

We may incur substantial losses and be subject to substantial liability claims as a result of our oil and gas operations.

 

We are not insured against all risks. Losses and liabilities arising from uninsured and underinsured events could materially and adversely affect our business, financial condition or results of operations. Our oil and natural gas exploration and production activities are subject to all of the operating risks associated with drilling for and producing oil and natural gas, including the possibility of:

 

Any of these risks could adversely affect our ability to conduct operations or result in substantial losses to our company. We may elect not to obtain insurance if we believe that the cost of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks generally are not fully insurable. If a significant accident or other event occurs and is not fully covered by insurance, then it could adversely affect us.

 

We have limited control over activities on properties we do not operate, which could reduce our production and revenues.

 

If we do not operate the properties in which we own an interest, we do not have control over normal operating procedures, expenditures or future development of underlying properties. The failure of an operator of our wells to adequately perform operations or an operator’s breach of the applicable agreements could reduce our production and revenues. The success and timing of our drilling and development activities on properties operated by others therefore depends upon a number of factors outside of our control, including the operator’s timing and amount of capital expenditures, expertise and financial resources, inclusion of other participants in drilling wells, and use of technology. Because we do not have a majority interest in most wells we do not operate, we may not be in a position to remove the operator in the event of poor performance.

 

Our use of 3-D seismic data is subject to interpretation and may not accurately identify the presence of oil and gas, which could adversely affect the results of our drilling operations.

 

Even when properly used and interpreted, 3-D seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. In addition, the use of 3-D seismic and other advanced technologies requires greater predrilling expenditures than traditional drilling strategies, and we could incur losses as a result of such expenditures. Thus, some of our drilling activities may not be successful or economical, and our overall drilling success rate or our drilling success rate for activities in a particular area could decline. We often gather 3-D seismic data over large areas. Our interpretation of seismic data delineates for us those portions of an area that we believe are desirable for drilling. Therefore, we may choose not to acquire option or lease rights prior to acquiring seismic data, and in many cases, we may identify hydrocarbon indicators before seeking option or lease rights in the location. If we are not able to lease those locations on acceptable terms, it would result in our having made substantial expenditures to acquire and analyze 3-D seismic data without having an opportunity to attempt to benefit from those expenditures.

 

Market conditions or operational impediments may hinder our access to oil and gas markets or delay our production.

 

In connection with our continued development of oil and gas properties, we may be disproportionately exposed to the impact of delays or interruptions of production from wells in these properties, caused by transportation capacity constraints, curtailment of production or the interruption of transporting oil and gas volumes produced. In addition, market conditions or a lack of satisfactory oil and gas transportation arrangements may hinder our access to oil and gas markets or delay our production. The availability of a ready market for our oil and natural gas production depends on a number of factors, including the demand for and supply of oil and natural gas and the proximity of reserves to pipelines and terminal facilities. Our ability to market our production depends substantially on the availability and capacity of gathering systems, pipelines and processing facilities owned and operated by third-parties. Additionally, entering into arrangements for these services exposes us to the risk that third parties will default on their obligations under such arrangements. Our failure to obtain such services on acceptable terms or the default by a third party on their obligation to provide such services could materially harm our business. We may be required to shut in wells for a lack of a market or because access to gas pipelines, gathering systems or processing facilities may be limited or unavailable. If that were to occur, then we would be unable to realize revenue from those wells until production arrangements were made to deliver the production to market.

We are subject to complex laws that can affect the cost, manner or feasibility of doing business.

 

Exploration, development, production and sale of oil and natural gas are subject to extensive federal, state, local and international regulation. We may be required to make large expenditures to comply with governmental regulations. Matters subject to regulation include:

 

 

Under these laws, we could be liable for personal injuries, property damage and other damages. Failure to comply with these laws also may result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties. Moreover, these laws could change in ways that could substantially increase our costs. Any such liabilities, penalties, suspensions, terminations or regulatory changes could materially adversely affect our financial condition and results of operations.

 

Our operations may incur substantial liabilities to comply with environmental laws and regulations.

 

Our oil and gas operations are subject to stringent federal, state and local laws and regulations relating to the release or disposal of materials into the environment or otherwise relating to environmental protection. These laws and regulations may require the acquisition of a permit before drilling commences; restrict the types, quantities, and concentration of materials that can be released into the environment in connection with drilling and production activities; limit or prohibit drilling activities on certain lands lying within wilderness, wetlands, and other protected areas; and impose substantial liabilities for pollution resulting from our operations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil, and criminal penalties, incurrence of investigatory or remedial obligations, or the imposition of injunctive relief. Under these environmental laws and regulations, we could be held strictly liable for the removal or remediation of previously released materials or property contamination regardless of whether we were responsible for the release or if our operations were standard in the industry at the time they were performed. Federal law and some state laws also allow the government to place a lien on real property for costs incurred by the government to address contamination on the property.

 

Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly material handling, storage, transport, disposal or cleanup requirements could require us to make significant expenditures to maintain compliance and may otherwise have a material adverse effect on our results of operations, competitive position, or financial condition as well as those of the oil and gas industry in general. For instance, recent scientific studies have suggested that emissions of certain gases, commonly referred to as “greenhouse gases”, including carbon dioxide and methane, may be contributing to warming of the Earth’s atmosphere. In response to such studies, President Obama has expressed support for, and it is anticipated that the current session of Congress will consider legislation to regulate emissions of greenhouse gases. In addition, more than one-third of the states, either individually or through multi-state regional initiatives, have already taken legal measures to reduce emission of these gases, primarily through the planned development of greenhouse gas emission inventories and/or regional greenhouse gas cap and trade programs. Also, as a result of the U.S. Supreme Court’s decision on April 2, 2007 in Massachusetts, et al. v. EPA, the EPA may be required to regulate greenhouse gas emissions from mobile sources (e.g., cars and trucks) even if Congress does not adopt new legislation specifically addressing emissions of greenhouse gases. The Court’s holding in Massachusetts that greenhouse gases fall under the federal Clean Air Act’s definition of “air pollutant” may also result in future regulation of greenhouse gas emissions from stationary sources under certain Clean Air Act programs. As a result of the Massachusetts decision, in April 2009, the EPA published a Proposed Endangerment and Cause or Contribute Findings for Greenhouse Gases Under the Clean Air Act. New legislation or regulatory programs that

restrict emissions of greenhouse gases in areas where we operate could adversely affect our operations by increasing costs. The cost increases would result from the potential new requirements to install additional emission control equipment and by increasing our monitoring and record-keeping burden.

 

Unless we replace our oil and natural gas reserves, our reserves and production will decline, which would adversely affect our cash flows and results of operations.

 

Unless we conduct successful development, exploitation and exploration activities or acquire properties containing proved reserves, our proved reserves will decline as those reserves are produced. Producing oil and natural gas reservoirs generally are characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Our future oil and natural gas reserves and production, and therefore our cash flow and income, are highly dependent on our success in efficiently developing and exploiting our current reserves and economically finding or acquiring additional recoverable reserves. We may not be able to develop, exploit, find or acquire additional reserves to replace our current and future production.

 

The loss of senior management or technical personnel could adversely affect us.

 

To a large extent, we depend on the services of our senior management and technical personnel. The loss of the services of our senior management or technical personnel, including James J. Volker, our Chairman, President and Chief Executive Officer; James T. Brown, our Senior Vice President; Rick A. Ross, our Vice President, Operations; Peter W. Hagist, our Vice President, Permian Operations; J. Douglas Lang, our Vice President, Reservoir Engineering/Acquisitions; David M. Seery, our Vice President of Land; Michael J. Stevens, our Vice President and Chief Financial Officer; or Mark R. Williams, our Vice President, Exploration and Development, could have a material adverse effect on our operations. We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals.

 

The unavailability or high cost of additional drilling rigs, equipment, supplies, personnel and oil field services could adversely affect our ability to execute our exploration and development plans on a timely basis or within our budget.

 

Shortages or the high cost of drilling rigs, equipment, supplies or personnel could delay or adversely affect our exploration and development operations, which could have a material adverse effect on our business, financial condition, results of operations or cash flows.

 

Competition in the oil and gas industry is intense, which may adversely affect our ability to compete.

 

We operate in a highly competitive environment for acquiring properties, marketing oil and gas and securing trained personnel. Many of our competitors possess and employ financial, technical and personnel resources substantially greater than ours, which can be particularly important in the areas in which we operate. Those companies may be able to pay more for productive oil and gas properties and exploratory prospects and to evaluate, bid for and purchase a greater number of properties and prospects than our financial or personnel resources permit. Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. Also, there is substantial competition for available capital for investment in the oil and gas industry. We may not be able to compete successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, attracting and retaining quality personnel and raising additional capital.

 

Our use of oil and natural gas price hedging contracts involves credit risk and may limit future revenues from price increases and result in significant fluctuations in our net income.

 

We enter into hedging transactions of our oil and natural gas production to reduce our exposure to fluctuations in the price of oil and natural gas. Our hedging transactions to date have consisted of financially settled crude oil and natural gas forward sales contracts, primarily costless collars, placed with major financial institutions. As of April 1, 2009, we had contracts, which include our 24.2% share of the Whiting USA Trust I hedges, covering the sale for the remainder of 2009 of between 489,190 and 529,808 barrels of oil per month

and between 134,874 and 138,706 MMBtu of natural gas per month. All our oil hedges will expire by November 2013, and all our natural gas hedges will expire by December 2012. See “Quantitative and Qualitative Disclosure about Market Risk” in our Form 10-Q for the Quarter ended March 31, 2009 for pricing and a more detailed discussion of our hedging transactions.

 

We may in the future enter into these and other types of hedging arrangements to reduce our exposure to fluctuations in the market prices of oil and natural gas, or alternatively, we may decide to unwind or restructure the hedging arrangements we previously entered into. Hedging transactions expose us to risk of financial loss in some circumstances, including if production is less than expected, the other party to the contract defaults on its obligations or there is a change in the expected differential between the underlying price in the hedging agreement and actual prices received. Hedging transactions may limit the benefit we may otherwise receive from increases in the price for oil and natural gas. Furthermore, if we do not engage in hedging transactions or unwind hedging transaction we previously entered into, then we may be more adversely affected by declines in oil and natural gas prices than our competitors who engage in hedging transactions. Additionally, hedging transactions may expose us to cash margin requirements.

 

Certain federal income tax deductions currently available with respect to oil and gas exploration and development may be eliminated as a result of future legislation.

 

In May 2009, President Obama’s Administration released revenue proposals in “General Explanations of the Administration’s Fiscal 2010 Revenue Proposals” that would, if enacted into law, make significant changes to United States tax laws, including the elimination of certain key U.S. federal income tax preferences currently available to oil and gas exploration and production companies. These changes include, but are not limited to (i) the repeal of the percentage depletion allowance for oil and gas properties, (ii) the elimination of current deductions for intangible drilling and development costs, (iii) the elimination of the deduction for certain U.S. production activities and (iv) an extension of the amortization period for certain geological and geophysical expenditures. In April 2009, the Oil Industry Tax Break Repeal Act of 2009, or the Senate Bill, was introduced in the Senate and includes many of the proposals outlined in the revenue proposals. It is unclear whether any such changes will actually be enacted or how soon any such changes could become effective. The passage of any legislation as a result of the revenue proposals, the Senate Bill or any other similar change in U.S. federal income tax law could eliminate certain tax deductions that are currently available with respect to oil and gas exploration and development, and any such change could negatively impact our financial condition and results of operations.

 

Risks Relating to the Convertible Preferred Stock

 

The convertible preferred stock ranks junior to all of our liabilities.

 

In the event of our bankruptcy, liquidation or winding-up, our assets will be available to pay obligations on the convertible preferred stock, including the conversion of your shares of the convertible preferred stock into cash, if we so elect, upon a fundamental change, only after all of our indebtedness and other liabilities have been paid. The rights of holders of the convertible preferred stock to participate in the distribution of our assets will rank junior to the prior claims of our creditors and any other equity holders. Consequently, if we are forced to liquidate our assets to pay our creditors, we may not have sufficient assets remaining to pay amounts due on any or all of the convertible preferred stock then outstanding. We may incur substantial amounts of additional debt and other obligations that will rank senior to the convertible preferred stock.

 

As a holding company, we rely on payments from our operating subsidiaries in order for us to make dividend payments on the convertible preferred stock.

 

Whiting Petroleum Corporation is a holding company with no significant operations of its own. Because our operations are conducted through our operating subsidiaries, we depend on dividends, advances and other payments from our subsidiaries in order to allow us to satisfy our financial obligations. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts to us, whether by dividends, advances or other payments. The ability of our subsidiaries to pay dividends and make other

payments to us depends on their earnings, capital requirements and general financial conditions and is restricted by, among other things, applicable corporate and other laws and regulations as well as agreements to which our subsidiaries may be a party.

 

We may not be able to pay dividends on the convertible preferred stock and no payment or adjustment will be made upon conversion for accumulated dividends.

 

The indentures governing our senior subordinated notes and other financing agreements that we enter into in the future may limit our ability to pay cash dividends on our capital stock. Specifically, under the indentures governing our senior subordinated notes, we may pay cash dividends and make other distributions on or in respect of our capital stock, including the convertible preferred stock, only if our fixed charge coverage ratio (as defined in the indentures) is at least 2.0 to 1 and certain other financial tests are met. In addition, under the indentures governing our senior subordinated notes and our credit agreement, we may not pay dividends on the convertible preferred stock if we are in default under our indentures or credit agreement. In the event that the indentures governing our senior subordinated notes or other financing agreements in the future restrict our ability to pay cash dividends on the convertible preferred stock, we will be unable to pay cash dividends on the convertible preferred stock unless we can refinance amounts outstanding under those agreements.

 

Under Delaware law, cash dividends on capital stock may only be paid from “surplus” or, if there is no “surplus,” from the corporation’s net profits for the then-current or the preceding fiscal year. Unless we operate profitably, our ability to pay cash dividends on the convertible preferred stock would require the availability of adequate “surplus,” which is defined as the excess, if any, of our net assets (total assets less total liabilities) over our capital. Further, even if adequate surplus is available to pay cash dividends on the convertible preferred stock, we may not have sufficient cash to pay dividends on the convertible preferred stock.

 

Our ability to pay dividends on the convertible preferred stock in shares of our common stock may be limited by the number of shares of common stock we are authorized to issue under our certificate of incorporation. As of March 31, 2009, we had issued 51,352,981 shares of our common stock out of 75,000,000 authorized shares under our certificate of incorporation.

 

Since we are not obligated to declare or pay dividends, we do not intend to do so to the extent we are restricted. No allowance or adjustment will be made upon conversion for any undeclared or, subject to limited exceptions, unpaid dividends.

 

The price of our common stock, and therefore of the convertible preferred stock, may fluctuate significantly, which may make it difficult for you to resell the convertible preferred stock, or common stock issuable pursuant to the terms thereof, when you want or at prices you find attractive.

 

The price of our common stock on the New York Stock Exchange has historically fluctuated significantly. We expect that the market price of our common stock will continue to fluctuate. Because the convertible preferred stock is convertible into shares of our common stock, volatility or depressed prices for our common stock could have a similar effect on the trading price of the convertible preferred stock. Holders who receive common stock pursuant to the terms of the convertible preferred stock will also be subject to the risk of volatility and depressed prices.

 

Our stock price can fluctuate as a result of a variety of factors, many of which are beyond our control. The following factors could affect our stock price:

 

 

•     general market conditions, including fluctuations in commodity prices; and

 

 

The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock.

 

Market interest rates may affect the value of our convertible preferred stock.

 

One of the factors that will influence the price of our convertible preferred stock will be the dividend yield on our convertible preferred stock relative to market interest rates. An increase in market interest rates could cause the market price of convertible preferred stock to go down. The trading price of the shares of our convertible preferred stock will also depend on many other factors, which may change from time to time, including:

 

 

We may issue additional series of preferred stock that rank equally to the convertible preferred stock as to dividend payments and liquidation preference.

 

Our certificate of incorporation and the certificate of designation for the convertible preferred stock do not prohibit us from issuing additional series of preferred stock that would rank equally to the convertible preferred stock as to dividend payments and liquidation preference. After accounting for the 3,000,000 shares (3,450,000 shares if the underwriters’ option to purchase additional shares is exercised in full) of the convertible preferred stock offered for sale pursuant to this prospectus supplement and prospectus and the 1,500,000 shares of preferred stock designated as Series A Junior Participating Preferred Stock in connection with the adoption of our stockholder rights plan, our certificate of incorporation provides that we have the authority to issue a remaining 500,000 shares (50,000 shares if the underwriters’ option to purchase additional shares is exercised in full) of preferred stock. The issuances of other series of preferred stock could have the effect of reducing the amounts available to the convertible preferred stock in the event of our liquidation. It may also reduce dividend payments on the convertible preferred stock if we do not have sufficient funds to pay dividends on all convertible preferred stock outstanding and outstanding parity preferred stock. Future issuances of preferred stock may adversely affect the market price for our common stock. Additional issuances and sales of preferred stock, or the perception that such issuances and sales could occur, may cause prevailing market prices for our common stock to decline and may adversely affect our ability to raise additional capital in the financial markets at times and prices favorable to us.

 

If you hold shares of our convertible preferred stock, you will not be entitled to any rights with respect to our common stock, but you will be subject to all changes made with respect to our common stock.

 

If you hold shares of our convertible preferred stock, you will not be entitled to any rights with respect to our common stock (including, without limitation, voting rights and rights to receive any dividends or other distributions on our common stock), but you will be subject to all changes affecting the common stock. You will have rights with respect to our common stock only if and when we deliver shares of common stock to you upon conversion of your shares of convertible preferred stock and, in certain cases, under the conversion rate adjustments applicable to our convertible preferred stock. For example, in the event that an amendment is proposed to our charter requiring stockholder approval and the record date for determining the stockholders of record entitled to vote on the amendment occurs prior to the delivery of common stock to you following a conversion, you will not be entitled to vote on the amendment, although you will nevertheless be subject to any changes in the powers, preferences or special rights of our common stock.

We may not have sufficient earnings and profits in order for distributions on the convertible preferred stock to be treated as dividends.

 

The dividends payable by us on the convertible preferred stock may exceed our current and accumulated earnings and profits, as calculated for U.S. federal income tax purposes, at the time of payment. If that occurs, it will result in the amount of the dividends that exceed such earnings and profits being treated first as a return of capital to the extent of the holder’s adjusted tax basis in the convertible preferred stock, and the excess, if any, over such adjusted tax basis as capital gain. Such treatment will generally be unfavorable for corporate holders and may also be unfavorable to certain other holders. See “Certain U.S. Federal Income Tax Considerations — Consequences to U.S. Holders of Convertible Preferred Stock or Common Stock.”

 

The additional shares of our common stock payable on our convertible preferred stock in connection with a fundamental change may not adequately compensate you for the lost option time value of your shares of our convertible preferred stock as a result of such fundamental change.

 

If a fundamental change occurs, you may be entitled to receive, in certain circumstances, in addition to the number of shares equal to the applicable conversion rate, an additional number of shares upon conversion as described under “Description of Preferred Stock — Determination of Make-Whole Premium.” The number of additional shares of our common stock will be determined based on the date on which the fundamental change becomes effective, and the price paid per share of common stock in the fundamental change transaction as described under “Description of Preferred Stock — Special Rights Upon a Fundamental Change.” While the additional shares of our common stock upon conversion is designed to compensate you for the lost option time value of your shares of convertible preferred stock as a result of the fundamental change, the increase is only an approximation of this lost value and may not adequately compensate you for your loss.

 

An active trading market for the convertible preferred stock does not exist and may not develop.

 

The convertible preferred stock are new issues of securities with no established trading market. Although we have been approved to list the convertible preferred stock on the New York Stock Exchange subject to official notice of issuance, we cannot assure you that the convertible preferred stock will be approved for listing or that a trading market will exist for those securities. Listing of the convertible preferred stock on the New York Stock Exchange does not guarantee that a trading market for the convertible preferred stock will develop or, if a trading market for the convertible preferred stock does develop, the depth or liquidity of that market or the ability of the holders to sell their convertible preferred stock.

 

There may be future sales or other dilution of our equity, which may adversely affect the market price of our common stock and the value of the convertible preferred stock.

 

Except as described under “Underwriting”, we are not restricted from issuing additional common stock, including securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The issuance of additional shares of our common stock upon conversion of the convertible preferred stock or other issuances of our common stock or convertible securities, including outstanding options, or otherwise will dilute the ownership interest of our common stockholders.

 

Sales of a substantial number of shares of our common stock or other equity-related securities in the public market could depress the market price of the convertible preferred stock, our common stock, or both, and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock or the value of the convertible preferred stock. The price of our common stock could be affected by possible sales of our common stock by investors who view the convertible preferred stock as a more attractive means of equity participation in our company and by hedging or arbitrage trading activity that we expect to develop involving our common stock as a result of this offering. The hedging or arbitrage could, in turn, affect the market price of the convertible preferred stock.

We have no plans to pay dividends on our common stock. You may not receive funds without selling the shares of common stock that you receive upon conversion of the convertible preferred stock.

 

We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently intend to retain future earnings, if any, to finance the expansion of our business. Our future dividend policy is within the discretion of our board of directors and will depend upon various factors, including our business, financial condition, results of operations, capital requirements and investment opportunities. In addition, the agreements governing our indebtedness limit our ability to pay dividends on our common stock.

 

Provisions in our organizational documents, our rights agreement and Delaware law could delay or prevent a change in control of our company, which could adversely affect the price of our common stock and therefore of the convertible preferred stock.

 

The existence of our rights agreement and some provisions in our organizational documents and under Delaware law could delay or prevent a change in control of our company, which could adversely affect the price of our common stock and therefore of the convertible preferred stock. The provisions in our certificate of incorporation and by-laws that could delay or prevent an unsolicited change in control of our company include a staggered board of directors, board authority to issue preferred stock, advance notice provisions for director nominations or business to be considered at a stockholder meeting and supermajority voting requirements. Our rights agreement provides each share of common stock, including shares offered through this prospectus supplement, the right to purchase one-hundredth of a share of our Series A Junior Participating Preferred Stock, which is exercisable only if a person or group has acquired, or announced an intention to acquire, 15% or more of our outstanding common stock. The rights have certain anti-takeover effects, in that they could have the effect of delaying or preventing a change in control of our company by causing substantial dilution to a person or group that attempts to acquire a significant interest in our company on terms not approved by our board of directors. In addition, Delaware law imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. See “Description of Capital Stock — Preferred Stock,” “Description of Capital Stock — Preferred Share Purchase Right” and “Description of Capital Stock — Delaware Anti-Takeover Law and Charter and By-law Provisions” in the accompanying prospectus.

 

We will receive estimated net proceeds of approximately $290.5 million from our sale of 3,000,000 shares of our convertible preferred stock in this offering, after deducting the underwriting discount and commissions and estimated offering expenses payable by us. If the underwriters’ exercise their overallotment option in full, we will receive estimated net proceeds of approximately $334.2 million, after deducting the underwriting discount and commissions and estimated offering expenses payable by us.

 

We expect to use the net proceeds from this offering to repay a portion of the debt outstanding under our credit agreement. The amounts repaid under the credit agreement will be available for us to reborrow in the future. Borrowings under our credit agreement were incurred to fund capital expenditures for development and exploration. Such borrowings currently bear interest at the rate of 3.0%, mature in April 2012 and totaled $670.0 million as of May 31, 2009.

 

Affiliates of certain of the underwriters are lenders under our credit facility, and accordingly, will receive a substantial portion of the proceeds from this offering in the form of the repayment of borrowings under such facility. See “Underwriting.”

We have not paid any dividends since we were incorporated in July 2003. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently intend to retain future earnings, if any, to finance the expansion of our business. Our future dividend policy is within the discretion of our board of directors and will depend upon various factors, including our results of operations, financial condition, capital requirements and investment opportunities. The agreements governing our indebtedness contain restrictions on our ability to declare and pay cash dividends. Under the indentures governing our senior subordinated notes, we may pay cash dividends on our capital stock, including the convertible preferred stock, only if our fixed charge coverage ratio (as defined in the indentures) is at least 2.0 to 1 and certain other financial tests are met. In addition, if we are in default under the agreements governing our indebtedness, we will not be able to pay dividends on our convertible preferred stock.

 

The following is a summary of certain provisions of the certificate of designation of our 6.25% convertible perpetual preferred stock (which we refer to as the “Convertible Preferred Stock”). The certificate of designation will be filed as an exhibit on a Current Report on Form 8-K and incorporated by reference into the registration statement of which this prospectus supplement and accompanying prospectus are a part. The following summary of the terms of Convertible Preferred Stock does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the certificate of designation. As used in this section, the terms “we,” “us” or “our” refer to Whiting Petroleum Corporation and not any of its subsidiaries.

 

General

 

Under our certificate of incorporation, our board of directors is authorized, without further stockholder action, to issue up to 5,000,000 shares of preferred stock, par value $0.001 per share, in one or more series, with such voting powers or without voting powers, and with such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions, as shall be set forth in the resolutions providing therefor. We have designated 1,500,000 shares of preferred stock as Series A Junior Participating Preferred Stock, par value $0.001 per share (the “Series A Junior Preferred”), which may be issued upon the exercise of our preferred share purchase rights. We currently have no outstanding shares of preferred stock. At the consummation of this offering, we will issue 3,000,000 shares of Convertible Preferred Stock. In addition, we have granted the underwriters an option to purchase up to 450,000 additional shares to cover overallotments. The series of Convertible Preferred Stock is limited to 3,000,000 shares (or up to 3,450,000 shares in the event the underwriters exercise their option). Please read “Description of Capital Stock” in the accompanying prospectus.

 

When issued, the Convertible Preferred Stock and any common stock issued upon the conversion of the Convertible Preferred Stock will be fully paid and nonassessable. The holders of the Convertible Preferred Stock will have no preemptive or preferential right to purchase or subscribe to stock, obligations, warrants or other securities of ours of any class. The transfer agent, registrar, redemption, conversion and dividend disbursing agent for shares of both the Convertible Preferred Stock and common stock is Computershare Trust Company, N.A.

 

The Convertible Preferred Stock is subject to mandatory conversion, as described below in “— Mandatory Conversion,” but is not redeemable by us.

 

Ranking

 

The Convertible Preferred Stock, with respect to dividend rights or rights upon our liquidation, winding-up or dissolution, ranks:

 

 

While any shares of Convertible Preferred Stock are outstanding, we may not authorize or issue any class or series of Senior Stock (or any security convertible into Senior Stock) without the affirmative vote or consent of the holders of at least 662/3% of the outstanding shares of Convertible Preferred Stock. Without the consent of any holder of Convertible Preferred Stock, however, we may authorize, increase the authorized amount of, or issue any class or series of Parity Stock or Junior Stock. See “— Voting Rights” below.

 

Dividends

 

Holders of shares of Convertible Preferred Stock will be entitled to receive, when, as and if declared by our board of directors out of funds legally available for payment, cumulative dividends at the rate per annum of 6.25% per share on the liquidation preference of $100 per share of Convertible Preferred Stock (equivalent to $6.25 per annum per share). Dividends on the Convertible Preferred Stock will be payable quarterly on March 15, June 15, September 15 and December 15 of each year, commencing on September 15, 2009 (each, a “Dividend Payment Date”) at such annual rate, and shall accumulate from the most recent date to which dividends have been paid, or if no dividends have been paid, from June 23, 2009. Dividends may be paid in cash or, where freely transferable by any non-affiliate recipient thereof, in common stock as provided below under “— Method of Payment of Dividends.” Dividends will be payable to holders of record as they appear on our stock register on the March 1, June 1, September 1 and December 1 immediately preceding each Dividend Payment Date (each, a “Record Date”). Accumulations of dividends on shares of Convertible Preferred Stock do not bear interest. Dividends payable on the Convertible Preferred Stock for any period less than a full dividend period (based upon the number of days elapsed during the period) will be computed on the basis of a 360-day year consisting of twelve 30-day months.

 

No dividend will be declared or paid upon, or any sum set apart for the payment of dividends upon, any outstanding share of the Convertible Preferred Stock with respect to any dividend period unless all dividends for all preceding dividend periods have been declared and paid or declared and a sufficient sum or number of shares of common stock have been set apart for the payment of such dividend, upon all outstanding shares of Convertible Preferred Stock.

 

No dividends or other distributions (other than a dividend or distribution payable solely in shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock) and cash in lieu of fractional shares) may be declared, made or paid, or set apart for payment upon, any Parity Stock or Junior Stock, nor may any Parity Stock or Junior Stock be redeemed, purchased or otherwise acquired for any consideration (or any money paid to or made available for a sinking fund for the redemption of any Parity Stock or Junior Stock) by us or on our behalf (except by conversion into or exchange for shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock)) unless all accumulated and unpaid dividends have been or contemporaneously are declared and paid, or are declared and a sum or number of shares of common stock sufficient for the payment thereof is set apart for such payment, on the Convertible Preferred Stock and any Parity Stock for all dividend payment periods terminating on or prior to the date of such declaration, payment, redemption, purchase or acquisition. Notwithstanding the preceding, if full dividends have not been paid on the Convertible Preferred Stock and any Parity Stock, dividends may be declared and paid on the Convertible Preferred Stock and such Parity Stock so long as the dividends are declared and paid pro rata so that the amounts of dividends declared per share on the Convertible Preferred Stock and such Parity Stock will in all cases bear to each other the same ratio that accumulated and unpaid dividends per share on the shares of the Convertible Preferred Stock and such Parity Stock bear to each other. Holders of shares of the Convertible Preferred Stock will not be entitled to any dividend, whether payable in cash, property or stock, in excess of full cumulative dividends.

 

Our ability to declare and pay cash dividends with respect to the Convertible Preferred Stock may be limited by the terms of the agreements governing our indebtedness and may be limited by applicable Delaware law. In addition, our ability to declare and pay dividends on the Convertible Preferred Stock in shares of our common stock may be limited by applicable Delaware law. See “Risk Factors — Risks Related to the Convertible Preferred Stock — We may not be able to pay dividends on the convertible preferred stock and no payment or adjustment will be made upon conversion for accumulated dividends.”

Method of Payment of Dividends

 

Subject to certain restrictions, we may generally pay any dividend on the Convertible Preferred Stock:

 

 

If we elect to make any such payment, or any portion thereof, in shares of our common stock, such shares shall be valued for such purpose, in the case of any dividend payment, or portion thereof, at 97% of the Market Value (as defined below under “— Conversion Price Adjustment”) as determined on the second Trading Day (as defined below under — “Mandatory Conversion”) immediately prior to the Record Date for such dividend.

 

We will make each dividend payment on the Convertible Preferred Stock in cash, except to the extent we elect to make all or any portion of such payment in shares of our common stock. We will give the holders of the Convertible Preferred Stock notice of any such election and the portion of such payment that will be made in cash and the portion that will be made in common stock 15 business days prior to the Record Date for such dividend.

 

Notwithstanding the above, we may not pay any portion of a dividend on the Convertible Preferred Stock by delivery of common stock unless (i) the common stock to be delivered as payment therefore is freely transferable by the recipient without further action on its behalf, other than by reason of the fact that such recipient is our affiliate, or (ii) a shelf registration statement relating to that common stock has been filed with the SEC and is effective to permit the resale of that common stock by the holders thereof.

 

Liquidation Preference

 

In the event of our voluntary or involuntary liquidation, winding-up or dissolution, each holder of Convertible Preferred Stock will be entitled to receive and to be paid out of our assets available for distribution to our stockholders, before any payment or distribution is made to holders of Junior Stock (including our common stock), a liquidation preference of $100 per share, plus accumulated and unpaid dividends on the shares to the date fixed for liquidation, winding-up or dissolution. If, upon our voluntary or involuntary liquidation, winding-up or dissolution, the amounts payable with respect to the liquidation preference of the Convertible Preferred Stock and all Parity Stock are not paid in full, the holders of the Convertible Preferred Stock and the Parity Stock will share equally and ratably in any distribution of our assets in proportion to the full liquidation preference and accumulated and unpaid dividends to which they are entitled. After payment of the full amount of the liquidation preference and accumulated and unpaid dividends to which they are entitled, the holders of the Convertible Preferred Stock will have no right or claim to any of our remaining assets. Neither the sale of all or substantially all our assets or business (other than in connection with our liquidation, winding-up or dissolution), nor our merger or consolidation into or with any other person, will be deemed to be our voluntary or involuntary liquidation, winding-up or dissolution.

 

The certificate of designation will not contain any provision requiring funds to be set aside to protect the liquidation preference of the Convertible Preferred Stock even though it is substantially in excess of the par value thereof.

 

Voting Rights

 

The holders of the Convertible Preferred Stock will have no voting rights except as set forth below or as otherwise required by Delaware law from time to time.

 

If dividends on the Convertible Preferred Stock are in arrears and unpaid for six or more quarterly periods (whether or not consecutive), the holders of the Convertible Preferred Stock, voting as a single class with any other preferred stock or preference securities having similar voting rights that are exercisable will be entitled at our next regular or special meeting of stockholders to elect two additional directors to our board of

directors. Upon the election of any additional directors, the number of directors that comprise our board shall be increased by such number of additional directors. Such voting rights and the terms of the directors so elected will continue until such time as the dividend arrearage on the Convertible Preferred Stock has been paid in full.

 

In addition, the affirmative vote or consent of the holders of at least 662/3% of the outstanding Convertible Preferred Stock will be required for the authorization or issuance of any class or series of Senior Stock (or any security convertible into Senior Stock) and for amendments to our certificate of incorporation by merger or otherwise that would affect adversely the rights of holders of the Convertible Preferred Stock. The certificate of designation will provide that the authorization of, the increase in the authorized amount of, or the issuance of any shares of any class or series of Parity Stock or Junior Stock will not require the consent of the holders of the Convertible Preferred Stock, and will not be deemed to affect adversely the rights of the holders of the Convertible Preferred Stock. Furthermore, the holders of Convertible Preferred Stock will not be entitled to vote with respect to any merger or similar transaction where the provisions described in “— Recapitalizations, Reclassifications and Changes in our Common Stock” are complied with if such transaction does not otherwise amend the terms of the Convertible Preferred Stock in a manner that would affect adversely the rights of holders of the Convertible Preferred Stock.

 

In all cases in which the holders of Convertible Preferred Stock shall be entitled to vote, each share of Convertible Preferred Stock shall be entitled to one vote.

 

Conversion Rights

 

Each share of Convertible Preferred Stock will be convertible, at any time, at the option of the holder thereof into a number of shares of our common stock equal to $100 divided by the Conversion Price at the time of conversion. The initial “Conversion Price” is $43.4163, and is subject to adjustment as described below. Based on the initial Conversion Price, each share of Convertible Preferred Stock is convertible into 2.3033 shares of our common stock. All shares of common stock distributed upon conversion will be freely transferable without restriction under the Securities Act of 1933 (other than by our affiliates) and such shares will be eligible for receipt in global form through the facilities of the Depository Trust Company (“DTC”).

 

The holders of shares of Convertible Preferred Stock at the close of business on a Record Date will be entitled to receive the dividend payment on those shares on the corresponding Dividend Payment Date notwithstanding the conversion of such shares following that Record Date or our default in payment of the dividend due on that Dividend Payment Date. However, shares of Convertible Preferred Stock surrendered for conversion during the period between the close of business on any Record Date and the close of business on the business day immediately preceding the applicable Dividend Payment Date must be accompanied by payment of an amount equal to the dividend payable on such shares on that Dividend Payment Date. A holder of shares of Convertible Preferred Stock on a Record Date who (or whose transferee) surrenders any shares for conversion on the corresponding Dividend Payment Date will receive the dividend payable by us on the Convertible Preferred Stock on that date, and the converting holder need not include payment in the amount of such dividend upon surrender of shares of Convertible Preferred Stock for conversion. Except as provided above with respect to a voluntary conversion, we will make no payment or allowance for unpaid dividends, whether or not in arrears, on converted shares or for dividends on the shares of common stock issued upon conversion.

 

Conversion Procedures

 

On the date of any conversion at the option of the holders, if a holder’s interest is a beneficial interest in a global certificate representing Convertible Preferred Stock, the holder must comply with DTC’s procedures for converting a beneficial interest in a global security.

If a holder’s interest is in certificated form, a holder must do each of the following in order to convert:

 

 

The date on which a holder complies with the foregoing procedures is the “conversion date.”

 

The conversion agent for the Convertible Preferred Stock is initially the transfer agent. A holder may obtain copies of the required form of the conversion notice from the conversion agent. The conversion agent will, on a holder’s behalf, convert the Convertible Preferred Stock into shares of our common stock, in accordance with the terms of the notice delivered by us. Payments of cash for dividends and in lieu of fractional shares and, if shares of our common stock are to be delivered, a stock certificate or certificates, will be delivered to the holder, or in the case of global certificates, a book-entry transfer through DTC will be made by the conversion agent. Such delivery will be made as promptly as practicable, but in no event later than three business days following the conversion date.

 

The person or persons entitled to receive the shares of common stock issuable upon conversion of the Convertible Preferred Stock will be treated as the record holder(s) of such shares as of the close of business on the applicable conversion date. Prior to the close of business on the applicable conversion date, the shares of common stock issuable upon conversion of the Convertible Preferred Stock will not be deemed to be outstanding for any purpose and you will have no rights with respect to the common stock, including voting rights, rights to respond to tender offers and rights to receive any dividends or other distributions on the common stock, by virtue of holding the Convertible Preferred Stock.

 

Mandatory Conversion

 

At any time on or after June 15, 2013, we may at our option cause all outstanding shares of the Convertible Preferred Stock to be automatically converted into that number of shares of common stock for each share of Convertible Preferred Stock equal to $100 divided by the then-prevailing Conversion Price, if the Closing Sale Price of our common stock equals or exceeds 120% of the then-prevailing Conversion Price for at least 20 Trading Days in a period of 30 consecutive Trading Days, including the last Trading Day of such 30-day period, ending on the Trading Day prior to our issuance of a press release announcing the mandatory conversion as described below.

 

The term “Trading Day” means a day during which trading in securities generally occurs on the New York Stock Exchange or, if our common stock is not listed on the New York Stock Exchange, on the principal other national or regional securities exchange on which our common stock is then listed or, if our common stock is not listed on a national or regional securities exchange, on the principal other market on which our common stock is then traded. If our common stock is not so listed or traded, “Trading Day” means a “business day.”

 

The “Closing Sale Price” of our common stock on any date means the closing sale price per share (or if no closing sale price is reported, the average of the closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) on such date as reported on the principal United States securities exchange on which our common stock is traded or, if our common stock is not listed on a United States national or regional securities exchange, as reported by Pink Sheets LLC. In the absence of such a quotation, the Closing Sale Price will be an amount determined in good faith by our board of directors to be the fair value of the common stock.

To exercise the mandatory conversion right described above, we must issue a press release for publication on the Dow Jones News Service or Bloomberg Business News (or if either such service is not available, another broadly disseminated news or press release service selected by us) prior to the opening of business on the first Trading Day following any date on which the conditions described in the first paragraph of this “Mandatory Conversion” section are met, announcing such a mandatory conversion. We will also give notice by mail or by publication (with subsequent prompt notice by mail) to the holders of the Convertible Preferred Stock (not more than four business days after the date of the press release) of the mandatory conversion announcing our intention to convert the Convertible Preferred Stock. The conversion date will be a date selected by us (which we refer to as the “Mandatory Conversion Date”) and will be no more than 10 days after the date on which we issue such press release.

 

In addition to any information required by applicable law or regulation, the press release and notice of a mandatory conversion shall state, as appropriate:

 

 

On and after the Mandatory Conversion Date, dividends will cease to accrue on the Convertible Preferred Stock called for a mandatory conversion and all rights of holders of such Convertible Preferred Stock will terminate except for the right to receive the shares of common stock issuable upon conversion thereof. The dividend payment with respect to the Convertible Preferred Stock called for a mandatory conversion on a date during the period between the close of business on any Record Date for the payment of dividends to the close of business on the corresponding Dividend Payment Date will be payable on such Dividend Payment Date to the record holder of such share on such Record Date if such share has been converted after such Record Date and prior to such Dividend Payment Date. Except as provided in the immediately preceding sentence with respect to a mandatory conversion, no payment or adjustment will be made upon conversion of Convertible Preferred Stock for accumulated and unpaid dividends or for dividends with respect to the common stock issued upon such conversion.

 

We may not authorize, issue a press release or give notice of any mandatory conversion unless, prior to giving the conversion notice, all accumulated and unpaid dividends on the Convertible Preferred Stock for periods ended prior to the date of such conversion notice shall have been paid.

 

In addition to the mandatory conversion provision described above, if there are fewer than 300,000 shares of Convertible Preferred Stock outstanding, we may, at any time on or after June 15, 2013, at our option, cause all such outstanding shares of the Convertible Preferred Stock to be automatically converted into that number of shares of common stock equal to $100 divided by the lesser of the then-prevailing Conversion Price and the Market Value as determined on the second Trading Day immediately prior to the Mandatory Conversion Date. The provisions of the immediately preceding four paragraphs shall apply to any such mandatory conversion; provided, however, that (1) the Mandatory Conversion Date will not be less than 15 days nor more than 30 days after the date on which we issue a press release announcing such mandatory conversion and (2) the press release and notice of mandatory conversion will not state the number of shares of common stock to be issued upon conversion of each share of Convertible Preferred Stock.

 

No Fractional Shares

 

No fractional shares of common stock or securities representing fractional shares of common stock will be issued upon conversion of the Convertible Preferred Stock, whether voluntary or mandatory, or in respect of dividend payments on the Convertible Preferred Stock made in common stock. Instead, we may elect to either make a cash payment to each holder that would otherwise be entitled to a fractional share or, in lieu of such cash payment, the number of shares of common stock to be issued to any particular holder upon conversion or in respect of dividend payments will be rounded up to the nearest whole share.

Conversion Price Adjustment

 

The Conversion Price shall be subject to the following adjustments (except as provided below):

 

(1) If we pay a dividend (or other distribution) in shares of common stock to all holders of our common stock, then the Conversion Price in effect immediately following the record date for such dividend (or distribution) shall be divided by the following fraction:

 

OS1

OS0

 

where

 

OS0		=		the number of shares of common stock outstanding immediately prior to the record date for such dividend or distribution; and
OS1		=		the sum of (A) the number of shares of common stock outstanding immediately prior to the record date for such dividend or distribution and (B) the total number of shares of common stock constituting such dividend.

 

(2) If we subdivide, combine or reclassify our shares of common stock into a greater or lesser number of shares of common stock, then the Conversion Price in effect immediately following the effective date of such share subdivision, combination or reclassification shall be divided by the following fraction:

 

OS1

OS0

 

where

 

OS0		=		the number of shares of common stock outstanding immediately prior to the effective date of such share subdivision, combination or reclassification; and
OS1		=		the number of shares of common stock outstanding immediately after the opening of business on the effective date of such share subdivision, combination or reclassification.

 

(3) If we issue to all holders of shares of our common stock rights, options or warrants entitling them, for a period of not more than 60 days from the date of issuance of such rights, options or warrants, to subscribe for or purchase shares of common stock at less than the Market Value (as defined below) determined on the Ex-Date (as defined below) for such issuance, then the Conversion Price in effect immediately following the close of business on the Ex-Date for such issuance shall be divided by the following fraction:

 

OS0 + X

OS0 + Y

 

where

 

OS0		=		the number of shares of common stock outstanding at the close of business on the record date for such issuance;
X		=		the total number of shares of common stock issuable pursuant to such rights, options or warrants; and
Y		=		the number of shares of common stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the Market Value determined as of the Ex-Date for such issuance.

 

To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of common stock are otherwise not delivered pursuant to such rights or warrants upon the exercise of such rights or warrants, the Conversion Price shall be readjusted to such Conversion Price that would

have then been in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of shares of common stock actually delivered. If such rights, options or warrants are only exercisable upon the occurrence of certain triggering events, then the Conversion Price shall not be adjusted until such triggering events occur. In determining the aggregate offering price payable for such shares of common stock, any consideration received for such rights, options or warrants and the value of such consideration (if other than cash, to be determined by our board of directors) shall be taken into account.

 

(4) If we make a distribution consisting exclusively of cash to all holders of the common stock, excluding (a) any cash that is distributed in a transaction or as part of a spin-off, (b) any dividend or distribution, in connection with our liquidation, dissolution, or winding up, and (c) any consideration payable in connection with a tender or exchange offer made by us or any of our subsidiaries, then, in each event, the Conversion Price in effect immediately following the record date for such distribution shall be divided by the following fraction:

 

SP0

SP0 − C

 

where

 

SP0		=		the average Closing Sale Price of our common stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend; and
C		=		the cash amount per share of common stock of the dividend.

 

In the event that a dividend described in this clause (4) is not so made, the Conversion Price shall be readjusted, effective as of the date our board of directors publicly announces its decision not to pay such dividend, to the Conversion Price that would then be in effect if such dividend had not been declared.

 

(5) If we or any of our subsidiaries successfully complete a tender or exchange offer for the common stock that involves the payment of consideration with a value per share of common stock exceeding the average Closing Sale Price of the common stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day immediately succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, then the Conversion Price in effect at the close of business on the last Trading Day of such period shall be divided by the following fraction:

 

AC + (SP0 x OS1)

OS0 x SP0

 

where

 

SP0		=		the average Closing Sale Price of our common stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day immediately succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer;
OS0		=		the number of shares of common stock outstanding immediately prior to the expiration of the tender or exchange offer, including any shares validly tendered and not withdrawn (the “Purchased Shares”);
OS1		=		the number of shares of common stock outstanding immediately after the expiration of the tender or exchange offer, less any Purchased Shares; and
AC		=		the aggregate cash and fair market value of the other consideration payable in the tender or exchange offer, as determined by our board of directors.

 

In the event that we, or one of our subsidiaries, is obligated to purchase shares of common stock pursuant to any such tender offer or exchange offer, but we, or such subsidiary, are permanently

prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall be readjusted to be such Conversion Price that would then be in effect if such tender offer or exchange offer had not been made.

 

Except as set forth in the preceding paragraph, if the application of this clause (5) to any tender offer or exchange offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer or exchange offer under this clause (5).

 

(6) If we distribute to all holders of shares of common stock evidences of indebtedness, shares of capital stock (other than common stock) or other assets (including securities, but excluding any dividend or distribution referred to in clauses (1) or (4) above; any rights or warrants referred to in clause (3) above; any consideration payable in connection with a tender or exchange offer made by us or any of our subsidiaries; and any dividend of shares of capital stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in the case of certain spin-off transactions as described below), then the Conversion Price in effect immediately following the close of business on the record date for such distribution shall be divided by the following fraction:

 

SP0

SP0 − FMV

 

where

 

SP0		=		the Closing Sale Price per share of common stock on the Trading Day immediately preceding the Ex-Date; and
FMV		=		the fair market value of the portion of the distribution applicable to one share of common stock on the Trading Day immediately preceding the Ex-Date as determined by our board of directors.

 

In a spin-off, where we make a distribution to all holders of shares of our common stock consisting of capital stock of any class or series, or similar equity interests of, or relating to, a subsidiary or other business unit, the Conversion Price shall be adjusted on the fourteenth Trading Day after the effective date of the distribution by dividing such Conversion Price in effect immediately prior to such fourteenth Trading Day by the following fraction:

 

MP0 + MPS

MP0

 

where

 

MP0		=		the average of the Closing Sale Price of the common stock over each of the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution; and
MPS		=		the average of the closing sale price of the capital stock or equity interests representing the portion of the distribution applicable to one share of common stock over each of the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution, or, as reported in the principal securities exchange or quotation system or market on which such shares are traded, or if not traded on a national or regional securities exchange or over-the-counter market, the fair market value of the capital stock or equity interests representing the portion of the distribution applicable to one share of common stock on such date as determined by our board of directors.

 

In the event that such distribution described in this clause (6) is not so made, the Conversion Price shall be readjusted, effective as of the date our board of directors publicly announces its decision not to pay such dividend or distribution, to the Conversion Price that would then be in effect if such dividend distribution had not been declared.

The term “Market Value” means the average of the per share volume-weighted average prices of our common stock for each day during a 10 consecutive Trading Day period ending immediately prior to the date of determination, as displayed under the heading “Bloomberg VWAP” on Bloomberg page “WLL.N <equity> AQR” (or its equivalent successor if such page is not available) in respect of the period from scheduled open of trading until the scheduled close of trading of the primary trading session on each such Trading Day (or if such volume-weighted average price is unavailable on any such day, the Closing Sale Price shall be used for such day). The per share volume-weighted average price on each such day will be determined without regard to after hours trading or any other trading outside of the regular trading session trading hours.

 

The term “Ex-Date,” when used with respect to any issuance or distribution, on the common stock or any other securities, means the first date on which the common stock or such other securities trade without the right to receive such issuance or distribution.

 

No adjustment of the Conversion Price will be required unless such adjustment would require an increase or decrease of at least 1% of the Conversion Price then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% of such Conversion Price; provided that on the date of an optional conversion (including any conversion in connection with a fundamental change) or the date of a mandatory conversion, adjustments to the Conversion Price will be made with respect to any such adjustment carried forward that has not been taken into account before such date.

 

We reserve the right to make such reductions in the Conversion Price in addition to those required in the foregoing provisions as we consider advisable in order that any event treated for federal income tax purposes as a dividend of stock or stock rights will not be taxable to the recipients. In the event we elect to make such a reduction in the Conversion Price, we shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 (the “Exchange Act”), and any other securities laws and regulations thereunder if and to the extent that such laws and regulations are applicable in connection with the reduction of the Conversion Price.

 

Rights or warrants distributed by us to all holders of common stock entitling the holders thereof to subscribe for or purchase shares of our capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of common stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of common stock, shall be deemed not to have been distributed (and no adjustment to the Conversion Price will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made in accordance with clause (6) above. In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of common stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of common stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise thereof, the Conversion Price shall be readjusted as if such expired or terminated rights and warrants had not been issued. To the extent that we have a rights plan or agreement in effect upon conversion of the Convertible Preferred Stock, which rights plan provides for rights or warrants of the type described in this clause, then upon conversion of Convertible Preferred Stock the holder will receive, in addition to the common stock to which he is entitled, a corresponding number of rights in accordance with the rights plan, unless a Trigger Event has occurred and the adjustments to the Conversion Price with respect thereto have been made in accordance with the foregoing. In lieu of any such adjustment, we may amend such applicable stockholder rights plan or agreement to provide that upon conversion of the Convertible Preferred Stock the holders will receive, in

addition to the common stock issuable upon such conversion, the rights that would have attached to such common stock if the Trigger Event had not occurred under such applicable stockholder rights plan or agreement.

 

No adjustment to the Conversion Price will be made with respect to any distribution or other transaction described above if holders of the Convertible Preferred Stock are entitled to participate in such distribution or transaction as if they held a number of shares of common stock issuable upon conversion of the Convertible Preferred Stock immediately prior to such event, without having to convert their Convertible Preferred Stock.

 

Recapitalizations, Reclassifications and Changes of Our Common Stock

 

In the case of any recapitalization, reclassification or change of our common stock (other than changes resulting from a subdivision or combination), a consolidation, merger or combination involving us, a sale, lease or other transfer to a third party of the consolidated assets of ours and our subsidiaries substantially as an entirety, or any statutory share exchange, in each case as a result of which our common stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof), then, at the effective time of the transaction, the right to convert each share of Convertible Preferred Stock will, without the consent of any holder of Convertible Preferred Stock, be changed into a right to convert it into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder would have received in respect of common stock issuable upon conversion of such shares immediately prior to such transaction (the “reference property”). In the event holders of our common stock have the opportunity to elect the form of consideration to be received in such transaction the reference property into which the Convertible Preferred Stock will be convertible will be deemed to be the weighted average of the types of consideration received by holders of our common stock who affirmatively make such an election. The certificate of designation will provide that we may not become a party to any such transaction unless its terms are consistent with the foregoing.

 

Special Rights Upon a Fundamental Change

 

We must give notice of each fundamental change (as defined below) to all record holders of the Convertible Preferred Stock, by the later of 20 business days prior to the anticipated effective date of the fundamental change and the first public disclosure by us of the anticipated fundamental change. If a holder converts its Convertible Preferred Stock at any time beginning at the opening of business on the Trading Day immediately following the effective date of such fundamental change and ending at the close of business on the 30th Trading Day immediately following such effective date, the holder will automatically receive a number of shares of our common stock equal to the greater of:

 

 

 

The foregoing provisions shall only be applicable with respect to conversions effected at any time beginning at the opening of business on the Trading Day immediately following the effective date of such fundamental change and ending at the close of business on the 30th Trading Day immediately following such effective date. In lieu of issuing the number of shares of common stock issuable upon conversion pursuant to the foregoing provisions, we may, at our option, make a cash payment equal to the Market Value for each such share of common stock otherwise issuable upon conversion or determined for the period ending on the effective date. Our notice of fundamental change will indicate if we will issue stock or pay cash upon conversion.

A “fundamental change” will be deemed to have occurred upon the occurrence of any of the following:

 

(1) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act or any successor provisions) other than us or any of our subsidiaries, is or becomes the beneficial owner, directly or indirectly, through a purchase, merger or other acquisition transaction, of 50% or more of the total voting power of all classes of our voting stock;

 

(2) we consolidate with, or merge with or into, another person (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) or any person consolidates with or merges with or into us, or we convey, transfer, lease or otherwise dispose of all or substantially all of our assets to any person (other than a direct or indirect wholly owned subsidiary of ours), other than:

 

(a) any transaction pursuant to which the holders of our capital stock immediately prior to the transaction collectively have the entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all classes of voting stock of the continuing or surviving person immediately after the transaction; or

 

(b) any merger solely for the purpose of changing our jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of common stock solely into shares of common stock of the surviving entity;

 

(3) the first day on which a majority of the members of our board of directors does not consist of “Continuing Directors”;

 

(4) we approve a plan of liquidation or dissolution; or

 

(5) our common stock ceases to be listed on a national or regional securities exchange or quoted on the New York Stock Exchange or an over-the-counter market in the United States.

 

“Continuing Directors” means (i) individuals who on the date of original issuance of the Convertible Preferred Stock constituted our board of directors or (ii) any new directors whose election to our board of directors or whose nomination for election by our stockholders was approved by at least a majority of our directors then still in office (or a duly constituted committee thereof) who were either directors on the date of original issuance of the Convertible Preferred Stock or whose election or nomination for election was previously so approved.

 

Beneficial ownership will be determined in accordance with Rule 13d-3 promulgated by the SEC under the Exchange Act, except that a person will be deemed to own any securities that such person has a right to acquire, whether such right is exercisable immediately or only after the passage of time. The term “person” includes any syndicate or group that would be deemed to be a “person” under Section 13(d)(3) of the Exchange Act.

 

Notwithstanding the foregoing, a fundamental change will be deemed not to have occurred in the case of a merger or consolidation if (i) at least 90% of the consideration for our common stock (excluding cash payments for fractional shares and cash payments pursuant to dissenters’ appraisal rights) in the merger or consolidation consists of common stock of a United States company traded on a national securities exchange (or which will be so traded when issued or exchanged in connection with such transaction) and (ii) as a result of such transaction or transactions the shares of Convertible Preferred Stock become convertible into such common stock.

 

The phrase “all or substantially all” of our assets is likely to be interpreted by reference to applicable state law at the relevant time, and will be dependent on the facts and circumstances existing at such time. As a result, there may be a degree of uncertainty in ascertaining whether a sale or transfer is of “all or substantially all” of our assets.

Determination of the Make-Whole Premium

 

If you elect to convert your shares of Convertible Preferred Stock upon the occurrence of a fundamental change, in certain circumstances, you will be entitled to receive, in addition to a number of shares of common stock issuable upon conversion based on the Conversion Price, an additional number of shares of common stock per share of Convertible Preferred Stock (the “additional shares” or the “make-whole premium”) upon conversion as described below.

 

We must give notice to all holders and to the conversion agent no later than the date of such fundamental change. Holders may surrender their shares of Convertible Preferred Stock for conversion and receive the additional shares described below only with respect to shares surrendered for conversion from and after the opening of business on the Trading Day immediately following the effective date of such fundamental change until the close of business on the 30th Trading Day following such effective date.

 

The number of additional shares will be determined by reference to the table below, based on the date on which the fundamental change becomes effective (the “effective date”) and the stock price (as defined below). If holders of our common stock receive only cash in the transaction constituting a fundamental change, the stock price shall be the cash amount paid per share. Otherwise, the stock price shall be the average of the Closing Sale Prices of our common stock on the five Trading Days prior to but not including the effective date of the transaction constituting a fundamental change.

 

The following table sets forth the stock price paid, or deemed paid, per share of our common stock in a transaction that constitutes the fundamental change, the effective date and the make-whole premium (expressed as a number of additional shares) to be paid upon a conversion in connection with a fundamental change:

 

 

 

 

The exact stock price and effective date may not be set forth on the table, in which case:

 

 

 

 

Our obligation to pay the make-whole premium could be considered a penalty, in which case the enforceability thereof would be subject to general equitable principles of reasonableness of economic remedies.

Book-Entry, Delivery and Form

 

We will initially issue the Convertible Preferred Stock in the form of one or more global securities. The global securities will be deposited with, or on behalf of, the Depository Trust Company (the “Depositary”) and registered in the name of the Depositary or its nominee. Except as set forth below, the global securities may be transferred, in whole and not in part, only to the Depositary or another nominee of the Depositary. Investors may hold their beneficial interests in the global securities directly through the Depositary if they have an account with the Depositary or indirectly through organizations which have accounts with the Depositary.

 

Shares of Convertible Preferred Stock that are issued as described below under “— Certificated Convertible Preferred Stock” will be issued in definitive form. Upon the transfer of Convertible Preferred Stock in definitive form, such Convertible Preferred Stock will, unless the global securities have previously been exchanged for Convertible Preferred Stock in definitive form, be exchanged for an interest in the global securities representing the liquidation preference of Convertible Preferred Stock being transferred.

 

The Depositary has advised us as follows: The Depositary is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary was created to hold securities of institutions that have accounts with the Depositary (“direct participants”) and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depositary’s participants include securities brokers and dealers (which may include the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to the Depositary’s book-entry system is also available to others such as banks, brokers, dealers and trust companies (“indirect participants”) that clear through or maintain a custodial relationship with a participant, whether directly or indirectly.

 

We expect that pursuant to procedures established by the Depositary, upon the deposit of the global securities with, or on behalf of, the Depositary, the Depositary will credit, on its book-entry registration and transfer system, the liquidation preference of the Convertible Preferred Stock represented by such global securities to the accounts of participants. The accounts to be credited shall be designated by the underwriters of such Convertible Preferred Stock. Ownership of beneficial interests in the global securities will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in the global securities will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by the Depositary (with respect to participants’ interests) and such participants and indirect participants (with respect to the owners of beneficial interests in the global securities other than participants). The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to transfer or pledge beneficial interests in the global securities.

 

To facilitate subsequent transfers, all Convertible Preferred Stock deposited by direct participants with the Depositary are registered in the name of its nominee. The deposit of Convertible Preferred Stock with the Depositary and its registration in the name of the Depositary’s nominee do not effect any change in beneficial ownership. The Depositary has no knowledge of the actual beneficial owners of the Convertible Preferred Stock; the Depositary’s records reflect only the identity of the direct participants to whose accounts such Convertible Preferred Stock is credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

 

Purchases of Convertible Preferred Stock under the Depositary system must be made by or through direct participants, which will receive a credit for the shares on the Depositary’s records. The ownership interest of each actual purchaser of each share is in turn to be recorded on the direct and indirect Participants’ records. Beneficial owners will not receive written confirmation from the Depositary of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the Convertible Preferred

Stock are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners.

 

So long as the Depositary, or its nominee, is the registered holder and owner of the global securities, the Depositary or such nominee, as the case may be, will be considered the sole legal owner and holder of the Convertible Preferred Stock evidenced by the global certificates for all purposes of such Convertible Preferred Stock and the certificate of designation. Except as set forth below, as an owner of a beneficial interest in the global certificates, you will not be entitled to have the Convertible Preferred Stock represented by the global securities registered in your name, will not receive or be entitled to receive physical delivery of certificated Convertible Preferred Stock in definitive form and will not be considered to be the owner or holder of any Convertible Preferred Stock under the global securities. We understand that under existing industry practice, in the event an owner of a beneficial interest in the global securities desires to take any action that the Depositary, as the holder of the global securities, is entitled to take, the Depositary will authorize the participants to take such action, and that the participants will authorize beneficial owners owning through such participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

 

All payments on Convertible Preferred Stock represented by the global securities registered in the name of and held by the Depositary or its nominee will be made to the Depositary or its nominee, as the case may be, as the registered owner and holder of the global securities.

 

We expect that the Depositary or its nominee, upon receipt of any payment on the global securities, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the liquidation preference of the global securities as shown on the records of the Depositary or its nominee. We also expect that payments by participants or indirect participants to owners of beneficial interest in the global securities held through such participants or indirect participants will be governed by standing instructions and customary practices and will be the responsibility of such participants or indirect participants. We will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the global securities for any Convertible Preferred Stock or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between the Depositary and its participants or indirect participants, or the relationship between such participants or indirect participants and the owners of beneficial interests in the global securities owning through such participants or indirect participants.

 

Although the Depositary has agreed to the foregoing procedures in order to facilitate transfers of interests in the global securities among participants or indirect participants of the Depositary, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither we nor the transfer agent will have any responsibility or liability for the performance by the Depositary or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

 

The information in this section concerning the Depositary and its book-entry system has been obtained from sources that we believe to reliable, but we take no responsibility for its accuracy.

 

Certificated Convertible Preferred Stock

 

Subject to certain conditions, the Convertible Preferred Stock represented by the global securities is exchangeable for certificated Convertible Preferred Stock in definitive form of like tenor as such Convertible Preferred Stock if (1) the Depositary notifies us that it is unwilling or unable to continue as Depositary for the global securities or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act and, in either case, a successor is not appointed within 90 days or (2) we, in our discretion, at any time determine not to have all of the Convertible Preferred Stock represented by the global securities. Any Convertible Preferred Stock that is exchangeable pursuant to the preceding sentence is exchangeable for certificated Convertible Preferred Stock issuable for such number of shares and registered in such names as the Depositary shall direct. Subject to the foregoing, the global securities are not exchangeable, except for global securities representing the same aggregate number of shares and registered in the name of the Depositary or its nominee.

 

The following is a summary of certain U.S. federal income tax considerations and, in the case of non-U.S. holders (as defined below), estate tax considerations, relevant to the purchase, ownership, disposition, and conversion of the convertible preferred stock and the ownership and disposition of any common stock received as dividends on the convertible preferred stock or upon conversion of the convertible preferred stock. The following summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations and judicial and administrative authority, all of which are subject to change, possibly with retroactive effect, or different interpretations. This summary does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to an investor’s decision to purchase shares of convertible preferred stock, nor any tax consequences arising under the laws of any state, locality or foreign jurisdiction. This summary also does not address tax consequences that may be applicable to special classes of investors including, but not limited to, tax-exempt organizations, insurance companies, banks or other financial institutions, partnerships or other pass-through entities or holders of interests therein, persons that at any time own more than 5% of the aggregate fair market value of the convertible preferred stock, dealers in securities or commodities, regulated investment companies, persons liable for the alternative minimum tax, U.S. expatriates and former long-term U.S. residents, U.S. holders whose functional currency is not the U.S. dollar, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, non-U.S. holders that are “controlled foreign corporations” or “passive foreign investment companies”, persons that will hold our convertible preferred stock or common stock as a position in a hedging transaction, “straddle”, “conversion transaction” or other risk reduction transaction, or persons deemed to sell convertible preferred stock under the constructive sale provisions of the Code. This summary is limited to taxpayers who will hold our convertible preferred stock and any common stock received in respect thereof as “capital assets” (generally, property held for investment).

 

Each potential investor should consult with its own tax adviser as to the U.S. federal, state, local, foreign and any other tax consequences of the purchase, ownership, conversion, and disposition of our convertible preferred stock and common stock.

 

Consequences to U.S. Holders of Convertible Preferred Stock or Common Stock

 

The discussion in this section is addressed to a holder of our convertible preferred stock and common stock received in respect thereof that is a U.S. holder for federal income tax purposes. You are a U.S. holder if you are a beneficial owner of convertible preferred stock or common stock and you are, for U.S. federal income tax purposes:

 

 

Dividends.  Distributions with respect to our convertible preferred stock and our common stock (other than certain stock distributions) will be taxable as dividend income when paid to the extent of our current and accumulated earnings and profits as determined for U.S. federal income tax purposes. To the extent that the amount of distributions with respect to our convertible preferred stock or common stock exceeds our current and accumulated earnings and profits, such excess will be treated first as a tax-free return of capital to the extent of the U.S. holder’s adjusted tax basis in such convertible preferred stock or common stock, as the case may be, and thereafter as capital gain.

Subject to certain exceptions for short-term and hedged positions, under current law distributions constituting dividends received by non-corporate holders prior to January 1, 2011 in respect of our convertible preferred stock and common stock generally are subject to tax at the long-term capital gain rate (currently a maximum rate of 15%, but scheduled to increase to ordinary income tax rates beginning January 1, 2011). Subject to similar exceptions for short-term and hedged positions, distributions on our convertible preferred stock and common stock constituting dividend income paid to holders that are U.S. corporations will qualify for the dividends received deduction. However, any distribution (or the portion of any distribution) that exceeds our current and accumulated earnings and profits will not be eligible for the dividends received deduction. A U.S. holder should consult its own tax adviser regarding the availability of the 15% dividend tax rate or the dividends received deduction, as applicable, in the light of its particular circumstances.

 

Common Stock Distributions on the Convertible Preferred Stock.  If we pay a distribution on the convertible preferred stock in the form of common stock, such distribution will be taxable for U.S. federal income tax purposes in the same manner as distributions described above under “— Dividends.” The amount of such distribution will equal the fair market value on the distribution date of the common stock distributed to a holder on that date. A holder’s tax basis in such common stock will equal the fair market value of such common stock on the distribution date, and such holder’s holding period for such common stock will begin on the day following the distribution date.

 

Sale or Other Disposition.  A. U.S. holder will generally recognize capital gain or loss on a sale or exchange of our convertible preferred stock or common stock equal to the difference between the amount realized upon the sale or exchange (not including any proceeds attributable to declared and unpaid dividends, if any, which will be taxable as described above to U.S. holders of record who have not previously included such dividends in income) and the holder’s adjusted tax basis in the shares sold or exchanged. Such capital gain or loss will be long-term capital gain or loss if the holder’s holding period for the shares sold or exchanged is more than one year. Long-term capital gains of non-corporate taxpayers are taxed at a preferred rate, currently a maximum 15% rate (but that rate is scheduled to increase to ordinary income tax rates beginning January 1, 2011). The deductibility of capital losses is subject to limitations.

 

If, following a fundamental change, a U.S. holder of the convertible preferred stock exercises the option described in “Description of Preferred Stock — Special Rights Upon a Fundamental Change” and we elect to satisfy the exercise by a payment in cash, the transaction will generally be treated as a redemption for U.S. federal income tax purposes. In the case of a redemption of our convertible preferred stock in this circumstance for cash, a redeemed U.S. holder will generally recognize capital gain or loss if the redemption meets at least one of the following requirements, as determined for federal income tax purposes: (i) the redemption is “not essentially equivalent to a dividend”, (ii) the redemption results in a “complete termination” of the holder’s interest in our stock (preferred and common), or (iii) the redemption is “substantially disproportionate” with respect to the holder of convertible preferred stock. If the redemption satisfies any of these requirements, the redemption will be treated as a sale or exchange of the convertible preferred stock and such holder will recognize capital gain or loss (as described in the preceding paragraph). If the redemption does not satisfy any of these requirements, the holder will be treated as having received a distribution on such stock (in an amount that generally will be equal to the amount of cash received in the redemption) with the general consequences described in “— Dividends” above.

 

In certain cases, a redeemed U.S. holder may be treated as having received an “extraordinary dividend,” within the meaning of Section 1059 of the Code. Investors that are U.S. corporations that receive an “extraordinary dividend” in respect of our convertible preferred stock generally would be required to reduce their basis in our convertible preferred stock (but not below zero) by the portion of any such dividend that is not taxed because of the dividends received deduction. To the extent the non-taxed portion of such dividend exceeds the corporate investor’s stock basis, such investor must treat such excess as gain from the sale or exchange of our convertible preferred stock for the taxable year in which such dividend is received. Non-corporate U.S. holders who receive an “extraordinary dividend” would be required to treat any losses on the sale of convertible preferred stock as long-term capital losses to the extent of such dividends received by them that qualify for the 15% tax rate.

Conversion of Convertible Preferred Stock into Common Stock.  As a general rule, a U.S. holder will not recognize any gain or loss in respect of the receipt of common stock upon the conversion of our convertible preferred stock other than cash received in lieu of a fractional share of common stock. Except to the extent of common stock treated as received in respect of any dividends in arrears, the adjusted tax basis of common stock received on conversion will equal the adjusted tax basis of the convertible preferred stock converted (reduced by the portion of adjusted tax basis allocated to any fractional shares of common stock exchanged for cash, as described below), and the holding period of such common stock received on conversion will generally include the period during which the convertible preferred stock was held prior to conversion. A U.S. holder of convertible preferred stock may recognize dividend income to the extent there are dividends in arrears on such convertible preferred stock at the time of conversion into common stock.

 

Cash received in lieu of a fractional share of common stock will generally be treated as a payment in a taxable exchange for such fractional share, and gain or loss will be recognized on the receipt of cash in an amount equal to the difference between the amount of cash received and the amount of adjusted tax basis allocable to the fractional share.

 

If a U.S. holder exercises its right to convert the convertible preferred stock into shares of common stock after a Record Date but before the Dividend Payment Date, then upon conversion, the U.S. holder generally will be required to pay to us in cash an amount equal to such declared dividend. In this case, the U.S. holder will be entitled to receive the dividend payment on the corresponding Dividend Payment Date. A U.S. holder should consult its own tax advisor with respect to the treatment of such cash payment and the subsequent receipt of such dividend payment.

 

Adjustment of Conversion Price.  The conversion price of the convertible preferred stock is subject to adjustment under certain circumstances. Treasury Regulations promulgated under Section 305 of the Code would treat a U.S. holder of our convertible preferred stock as having received a constructive distribution includable in such U.S. holder’s income in the manner described under “— Dividends,” above, if and to the extent that certain adjustments in the conversion price increase the proportionate interest of the U.S. holder in our earnings and profits. For example, a decrease in the conversion price to reflect a taxable dividend to holders of common stock will generally give rise to a deemed taxable dividend to the holders of convertible preferred stock to the extent of an allocable portion of our current and accumulated earnings and profits. In addition, an adjustment to the conversion price of our convertible preferred stock or a failure to make such an adjustment could potentially give rise to constructive distributions to U.S. holders of our common stock. Thus, under certain circumstances, U.S. holders may recognize income in the event of a constructive distribution even though they may not receive any cash or property. Adjustments to the conversion price made pursuant to a bona fide reasonable adjustment formula which has the effect of preventing dilution in the interest of the U.S. holders of the convertible preferred stock, however, generally will not be considered to result in a constructive dividend distribution.

 

Information Reporting and Backup Withholding on U.S. Holders.  Certain U.S. holders will be subject to information reporting with respect to the payment of dividends on our convertible preferred stock or common stock and the payment of proceeds on the sale of our convertible preferred stock, and backup withholding may apply unless the U.S. holder provides proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with applicable requirements of the backup withholding rules.

 

Any amount withheld under the backup withholding rules from a payment to a holder is allowable as a credit against such holder’s U.S. federal income tax, which may entitle the holder to a refund, provided that the holder provides the required information to the Internal Revenue Service (“IRS”). Moreover, certain penalties may be imposed by the IRS on a holder who is required to furnish information but does not do so in the proper manner. Holders are urged to consult their own tax advisors regarding the application of backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from backup withholding under current Treasury Regulations.

 

Consequences to Non-U.S. Holders of Convertible Preferred Stock or Common Stock

 

The discussion in this section is addressed to holders of our convertible preferred stock and common stock received in respect thereof that are non-U.S. holders. You are a non-U.S. holder if you are a beneficial owner of convertible preferred stock or common stock received in respect thereof and you are not a U.S. holder.

 

Dividends.  Generally, dividends (including any constructive distributions taxable as dividends as described below and any cash paid upon a conversion or redemption that is treated as a dividend) paid to a non-U.S. holder with respect to our convertible preferred stock or our common stock will be subject to a 30% U.S. withholding tax, or such lower rate as may be specified by an applicable tax treaty. Because we are a “United States real property holding corporation” (“USRPHC”) for U.S. federal income tax purposes (see “— Sale or Other Disposition” below), distributions in excess of our current and accumulated earnings and profits generally will be subject to withholding at a rate not less than 10%.

 

Dividends that are effectively connected with a trade or business carried on by a non-U.S. holder within the United States, and, to the extent an applicable treaty provides, attributable to a permanent establishment maintained by the non-U.S. holder, will generally be subject to U.S. federal income tax on a net basis at applicable individual or corporate rates but will not be subject to U.S. withholding tax if certain certification requirements are satisfied. A non-U.S. holder can generally meet the certification requirements by providing a properly executed IRS Form W-8ECI or appropriate substitute form to us or our paying agent. A non-U.S. holder that is a corporation may also be subject to a “branch profits tax” at a 30% rate (or such lower rate as may be specified by an applicable tax treaty) on the deemed repatriation from the United States of its “effectively connected earnings and profits,” subject to certain adjustments. Under applicable Treasury Regulations, a non-U.S. holder (including, in certain cases of non-U.S. holders that are entities, the owner or owners of such entities) will be required to satisfy certain certification requirements in order to claim a reduced rate of withholding pursuant to an applicable tax treaty.

 

Sale or Other Disposition.  A non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on income or gain realized on the sale, exchange or redemption of our convertible preferred stock or our common stock (not including any amounts attributable to declared and unpaid dividends, which will be taxable to a non-U.S. holder as described above under “— Dividends”) unless:

 

 

We believe we currently are a USRPHC. In general, gain on the sale or other disposition of stock of a USRPHC that is “regularly traded” on an established securities market will be subject to U.S. federal income tax only in the case of a holder that owns more than 5% of the total fair market value of that class of stock at any time during the five-year period ending on the date of disposition. If a non-regularly traded class of stock is convertible into a regularly traded class of stock, gain on the sale of that non-regularly traded stock will be subject to U.S. federal income tax only if, on any date on which such stock was acquired by the holder, the non-regularly traded stock acquired by such holder (including all previously acquired stock of the same class) had a fair market value greater than 5% of the regularly traded class of the corporation’s stock into which it is convertible as measured on such date.

 

If the convertible preferred stock is considered to be “regularly traded,” gain recognized by a holder that owns more than 5% of the convertible preferred stock would be subject to U.S. federal income tax. We can provide no assurance that the convertible preferred stock will not be considered regularly traded under the relevant rules. If the convertible preferred stock is not considered to be regularly traded, gain recognized on a sale of convertible preferred stock would be subject to U.S. federal income tax only in the case of a

non-U.S. holder that owned, as of the date of any acquisition of such convertible preferred stock, an amount of convertible preferred stock having a fair market value greater than 5% of the outstanding common stock into which it is convertible as measured on such date, provided the common stock continues to be regularly traded on an established securities market.

 

Non-U.S. holders that may be treated as actually or constructively owning more than 5% of our convertible preferred stock or common stock should consult their own tax advisors with respect to the U.S. federal income tax consequences of the ownership and disposition of convertible preferred stock or common stock.

 

Conversion of Convertible Preferred Stock into Common Stock.  A non-U.S. holder generally will not recognize any gain or loss by reason of receiving common stock in exchange for convertible preferred stock upon conversion of the convertible preferred stock, except gain or loss will be recognized with respect to any cash received in lieu of fractional shares. It is possible that common stock treated as received in respect of any dividends in arrears may be taxed as dividend income in the manner described above under “— Dividends”. In such case, any withholding tax on stock treated as a dividend may be withheld from cash dividends, shares of our common stock or sale proceeds subsequently paid or credited to a non-U.S. holder.

 

Adjustment of Conversion Price.  As described above under “Consequences to U.S. Holders of Convertible Preferred Stock or Common Stock — Adjustment of Conversion Price,” adjustments in the conversion price (or failures to adjust the conversion price) that result in an increase in the proportionate interest of a non-U.S. holder in our earnings and profits could result in deemed distributions to the non-U.S. holder that are taxed as described under “— Dividends.” Any withholding tax on such a deemed distribution could be withheld from cash dividends, shares of our common stock or sale proceeds subsequently paid or credited to a non-U.S. holder.

 

U.S. Federal Estate Tax.  Our convertible preferred stock and common stock owned or treated as owned by an individual who is not a citizen or resident of the United States (as specially defined for U.S. federal estate tax purposes) at the time of death will be included in the individual’s gross estate for U.S. federal estate tax purposes, unless an applicable estate tax or other treaty provides otherwise and, therefore, may be subject to U.S. federal estate tax.

 

Information Reporting and Backup Withholding.  Payment of dividends (including constructive dividends), and the tax withheld with respect thereto, is subject to information reporting requirements. These information reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable tax treaty or withholding was not required because the dividends were effectively connected with a trade or business in the United States conducted by the non-U.S. holder. Copies of the information returns reporting such dividends and withholding may also be made available under the provisions of an applicable tax treaty or agreement with the tax authorities in the country in which the non-U.S. holder resides. U.S. backup withholding will generally apply to the payment of dividends to non-U.S. holders unless such non-U.S. holders furnish to the payor a Form W-8BEN (or other applicable form) or otherwise establish an exemption.

 

Payment by a U.S. office of a broker of the proceeds of a sale of our convertible preferred stock or common stock is subject to both backup withholding and information reporting unless the non-U.S. holder, or beneficial owner thereof, as applicable, certifies that it is a non-U.S. holder on Form W-8BEN, or otherwise establishes an exemption. Subject to certain exceptions, backup withholding and information reporting generally will not apply to a payment of proceeds from the sale of our convertible preferred stock or common stock if such sale is effected through a foreign office of a broker, provided that the broker does not have certain U.S. connections.

 

Any amount withheld under the backup withholding rules from a payment to a non-U.S. holder is allowable as a credit against such holder’s U.S. federal income tax liability, which may entitle the holder to a refund if in excess of such liability, provided that the holder timely provides the required information to the IRS. Non-U.S. holders are urged to consult their own tax advisers regarding the application of backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from backup withholding under current Treasury Regulations.

Subject to the terms and conditions described in a purchase agreement among us and the underwriters, we have agreed to sell to the underwriters, and the underwriters severally have agreed to purchase from us, the number of shares listed opposite their names below.
