Item 5. Interest in Securities of the Issuer (a) - (b) As a result of PSC's ownership 94,425 shares of Issuer Common Stock, the Stockholder Agreements and the Option Agreement, PSC may be deemed to be the beneficial owner of 2,227,867 shares of Issuer Common Stock, which constitutes approximately 25.1% of the issued and outstanding shares of Issuer Common Stock, after giving effect to the exercise of the Option, and based on the Issuer's representation in the Merger Agreement that there were 7,412,572 shares of Issuer Common Stock issued and outstanding at the close of business on October 18, 2002. Pursuant to the Stockholder Agreement, each Stockholder has agreed, among other things, to (a) vote the shares of Issuer Common Stock owned by such Stockholder (i) in favor of the adoption of the Merger Agreement, (ii) against any Acquisition Proposal (as defined in the Merger Agreement) and against any proposal for action or agreement that would result in a breach of any covenant, representation or warranty, or any other obligation or agreement of the Issuer under the Merger Agreement or which is reasonably likely to result in any of the Issuer's obligations under the Merger Agreement not being fulfilled, any change in the directors of the Issuer, any change in the present capitalization of the Company or any amendment to the Company's Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws, any other material change in the Issuer's corporate structure or business or any other action which in the case of each of the matters referred to in this clause (ii) could reasonably be expected to impede, interfere with, delay, postpone or materially adversely affect the transactions contemplated by the Merger Agreement or the likelihood of such transactions being consummated and (iii) in favor of any other matter necessary for consummation of the transactions contemplated by the Merger Agreement that is considered at any such meeting of stockholders or in such consent, and in connection therewith to execute any documents which are necessary or appropriate in order to effectuate the foregoing, including the ability for Merger Sub or its nominees to vote such Subject Shares directly; provided, however, that the Stockholder shall not be required to vote for any action that would decrease the consideration to be received by the stockholders of the Issuer in respect of their shares in the Merger; and (b) during the term Page 5 of 10 pages of the agreement not to (i) transfer (which term shall include, without limitation, any sale, assignment, gift, pledge, hypothecation or other disposition), or consent to any transfer of, any or all of the Stockholder's shares or any interest therein, or create or permit to exist any Encumbrance (as defined below) on such shares, (ii) enter into any contract, option or other agreement or understanding with respect to any transfer of any or all of such shares or any interest therein, (iii) grant any proxy, power-of-attorney or other authorization in or with respect to such shares, (iv) deposit such shares into a voting trust or enter into a voting agreement or arrangement with respect to such shares or (v) take any other action that would in any way restrict, limit or interfere with the performance of the Stockholder's obligations hereunder or the transactions contemplated hereby or by the Merger Agreement. By their execution of the Stockholder Agreements, each Stockholder has appointed PSC and Merger Sub, or any nominee of PSC and Merger Sub, with full power of substitution and resubstitution, at any time during the term of the agreement, as the Stockholder's true and lawful attorney and proxy (the "Attorney"). The name of each Stockholder and the number of Subject Shares owned of record or beneficially by each Stockholder are set forth in Schedule I to the Stockholder Agreements, copies of which are filed herewith as Exhibit 2 and 3 hereto. In exercising its right to vote the Subject Shares as proxy and attorney-in-fact of the Stockholders, the Attorney's rights are limited to voting the Subject Shares at every annual, special, adjourned or postponed meeting of the stockholders of the Issuer, at which any proposal described above is considered and includes the right to sign the Stockholder's name (as stockholder) to any consent, certificate or other document in lieu of any such meeting that Delaware law may permit or require. In addition to the voting agreements and arrangements described above, each of the Stockholder Agreements entered into by the six members of Issuer's board of directors also provides for the grant to PSC of an option to purchase any and all of the shares of Issuer Common Stock owned by such director at a purchase price of $3.19 per share. The options become exercisable if the Merger Agreement is terminated: (A) by PSC (i) after Issuer's stockholders do not approve the merger, (ii) after Issuer's board of directors fails to recommend, or withdraws or modifies its recommendation, that Issuer's stockholders approve the merger, (iii) after Issuer materially breaches the Merger Agreement or (iv) after PSC exercises its option to commence a tender offer for Issuer Common Stock and Issuer's board of directors fails to recommend, or withdraws or modifies its recommendation, that Issuer's stockholders tender their shares; or (B) by Issuer after January 31, 2003 following Issuer's receipt of another acquisition proposal. The Stockholder Agreements terminate upon the earlier of (a) the consummation of the purchase of all of the Subject Shares pursuant to the Offer (as defined in the Merger Agreement), (b) the termination of the Merger Agreement, (c) the written mutual consent of PSC and the Stockholder, and (d) such date and time as the Merger shall become effective in accordance with the terms of the Merger Agreement. Page 6 of 10 pages Pursuant to the Option Agreement, the Issuer has granted PSC the Option to purchase, in whole or in part, an aggregate of up to 1,475,000 shares of Issuer Common Stock (representing approximately 19.9% of the outstanding shares of Issuer Common Stock as of the date of the Option Agreement) at an exercise price of $3.19 per share prior to the Expiration Date (as defined below). The Option becomes exercisable if the Merger Agreement is terminated by PSC (i) after Issuer's board of directors fails to recommend, or withdraws or modifies its recommendation, that Issuer's stockholders approve the merger, (ii) after PSC exercises its option to commence a tender offer for Issuer Common Stock and Issuer's board of directors fails to recommend, or withdraws or modifies its recommendation, that Issuer's stockholders tender their shares, (iii) after Issuer's stockholders do not approve the merger following the receipt by Issuer of another acquisition proposal that is consummated within one year of termination and (iv) after Issuer intentionally and materially breaches the Merger Agreement. The Expiration Date means the first to occur prior to PSC's exercise of the Option of (a) the closing of the merger, (b) written notice of termination of the Option Agreement by PSC, (c) termination of the Merger Agreement under circumstances where PSC would not be entitled to payment of a termination fee, or (d) the date that is 12 months from the date of termination of the Merger Agreement. Based on the foregoing, PSC may be deemed to have (i) sole voting and sole dispositive power with respect to the 94,425 shares beneficially owned and the 1,475,000 shares subject to the Option Agreement, (ii) shared voting and shared dispositive power with respect to the 225,819 shares subject to the Stockholder Agreements entered into by the Issuer's directors and (iii) shared voting power with respect to the 432,623 shares subject to the Stockholder Agreements entered into by the Issuer's other Stockholders.

(c) Neither PSC nor, to the knowledge of PSC, any person named in Schedule A, has effected any transaction in the Issuer Common Stock during the past 60 days. (d) Not applicable. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer Other than as described in Items 3, 4 and 5 and the agreements incorporated herein by reference and set forth as exhibits hereto, to the knowledge of PSC, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any Page 7 of 10 pages securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies .
