This Amendment and the Schedule 13D relate to the Company's Common Stock. Unless the context otherwise requires, references herein to the "Common Stock" are to the Common Stock of the Company, par value $0.001 per share. This Amendment to the Schedule 13D is being filed after a direct acquisition of 4,000,000 shares of the Common Stock, which is described in Item 3 hereof. Item 2. Identity and Background. (a) Schedule I to Item 2(a) of the Schedule 13D is hereby amended in its entirety and is replaced with Schedule I attached hereto. Item 3. Source and Amount of Funds or Other Consideration. Item 3 of the Schedule 13D is hereby amended in its entirety to read as follows: "Pursuant to a Stock Purchase Agreement made as of November 7, 2001, by and between the Company and WPV (the "Stock Purchase Agreement"), WPV agreed to purchase from the Company, and the Company agreed to sell to WPV, 4,000,000 shares of the Common Stock (the "Purchased Shares") at a price of $1.25 per share, for an Page 5 of 17 Pages aggregate purchase price of $5,000,000. The closing of the purchase and sale of the Purchased Shares occurred as of November 30, 2001. Pursuant to an Agreement to Issue Warrant and Grant of Security Interest, dated as of March 9, 2001, between the Company and WPV, Inc., a Delaware corporation and a wholly owned subsidiary of WPV, WPV, Inc. received a warrant to acquire 1,375,000 shares of the Common Stock at a price of $8.00 per share (the "Warrant") in exchange for consideration in the form of an unlimited guaranty delivered by WPV, Inc. (the "Guaranty") of a $15,000,000 revolving line of credit issued by Fleet National Bank (the "Bank") in favor of the Company and the issuance by The Chase Manhattan Bank USA, N.A. of a letter of credit for the benefit of the Bank on the account of WPV, Inc. The Warrant is immediately exercisable and expires on March 9, 2008. With effect as of March 9, 2001, WPV, Inc. distributed the Warrant to WPV as a dividend. Prior to the Company's initial public offering of the Common Stock in July 1999, WPV held 3,544,972 shares of the Common Stock directly and held immediately exercisable warrants to acquire 116,666 shares of the Common Stock at a price of $9.00 per share. These warrants were acquired in transactions involving first the issuance of an unlimited guaranty delivered by WPV with respect to a prior revolving line of credit for the Company and subsequently the loan by WPV of funds to the Company. Both of these prior financings have been repaid in full. The remainder of the shares of Common Stock held by WPV were acquired either in open market purchases or privately negotiated transactions involving less than 2% of the outstanding shares of Common Stock. Page 6 of 17 Pages All of the funds required to acquire the warrants and shares of Common Stock held by WPV were obtained from the working capital of WPV." Item 4. Purpose of Transaction. Item 4 of the Schedule 13D is hereby amended in its entirety to read as follows: "The acquisition by WPV of the Common Stock was effected because of the Reporting Entities' belief that the Common Stock represents an attractive investment. Prior acquisitions of the Common Stock and warrants of the Company were made on the basis of similar beliefs. The Reporting Entities may from time to time acquire additional shares of Common Stock or engage in discussions with the Company concerning further acquisitions of shares of Common Stock, warrants to acquire shares of Common Stock, or further investments by them in the Company, which acquisitions or investments could be material. The Reporting Entities intend to review their investment in the Company on a continuing basis and, depending upon the price and availability of shares of Common Stock, subsequent developments affecting the Company, the Company's business and prospects, other investment and business opportunities available to the Reporting Entities, general stock market and economic conditions, tax considerations and other factors considered relevant, may decide at any time to increase, or to decrease, the size of their investment in the Company. Except as set forth above in this statement, none of the Reporting Entities nor, to the best of their knowledge, any person listed in Schedule I hereto, has any plans or proposals that relate to or would result in: (a) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (b) an Page 7 of 17 Pages extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Company or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the present capitalization or dividend policy of the Company; (f) any other material change in the Company's business or corporate structure; (g) changes in the Company's charter, By-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person; (h) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action similar to any of those enumerated above." Item 5. Interest in Securities of the Issuer. Item 5 of the Schedule 13D is hereby amended in its entirety to read as follows: "(a) As of December 7, 2001 WPV beneficially owned 9,153,304 shares of the Common Stock. By reason of their respective relationships with WPV, each of the Reporting Entities may be deemed under Rule 13d-3 of the Exchange Act to own beneficially all of the shares of the Common Stock that WPV beneficially owns. The 9,153,304 Shares of the Common Stock represented approximately 54.0% of the outstanding Common Stock, based on: (i) the 11,475,503 shares of Common Stock Page 8 of 17 Pages outstanding as of September 30, 2001, as represented by the Company in its Form 10-Q for the quarter ended September 30, 2001; (ii) the 4,000,000 newly issued shares of Common Stock issued to WPV in connection with the purchase and sale under the Stock Purchase Agreement; and (iii) the immediately exercisable warrants to acquire 1,491,666 shares of the Common Stock held by WPV as of December 7, 2001. (b) WPV has the sole power to vote or to direct the vote and to dispose or to direct the disposition with respect to the 9,153,304 shares of Common Stock beneficially owned by WPV. By virtue of its ownership position in WPV, WP may be deemed to, and, by virtue of their control position with respect to WPV, WP and WP LLC may be deemed to, have shared power to vote or to direct the vote and to dispose or to direct the disposition with respect to the 9,153,304 shares of Common Stock beneficially owned by WPV. (c) During the last sixty days the acquisition of the Purchased Shares under the Stock Purchase Agreement was the only transaction involving the Common Stock effected by the Reporting Entities or by any of the other Persons set forth on Schedules I and II hereto. (d) Except as set forth in this Item 5, no person other than each respective record owner referred to herein of securities is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, such securities. (e) Not applicable." Page 9 of 17 Pages Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. The Stock Purchase Agreement was entered into as of November 7, 2001 and is described herein in Item 3. The summary of the Stock Purchase Agreement is qualified in its entirety by reference to the Stock Purchase Agreement, which is incorporated herein by reference to Exhibit 10.22 to the Company's Form 10-Q for the period ended September 30, 2001, filed with the Commission on November 14, 2001. Pursuant to the terms of an Amended and Restated Registration Rights Agreement (the "Registration Rights Agreement"), dated as of December 30, 1998, among the Company, WPV and certain other shareholders of the Company, as amended by an Amendment No. 1 to the Registration Rights Agreement, effective as of March 9, 2001, by and among the Company, WPV and WPV, Inc. (the "Registration Rights Agreement Amendment"), the Company has agreed, among other things, to provide WPV and certain other shareholders with demand and piggyback registration rights with respect to certain shares of the Common Stock and certain securities of the Company convertible into shares of the Common Stock. Pursuant to the Registration Rights Agreement, WPV and the other shareholders party thereto have agreed to be bound by certain restrictions on the transfer of shares of the Common Stock and certain other securities of the Company. In connection with the acquisition of the Warrant, the Registration Rights Agreement was amended by execution of the Registration Rights Agreement Amendment to provide registration rights with respect to all of the shares of the Common Stock issuable upon exercise of the warrants then held by WPV and WPV, Inc., and up to an additional 1,000,000 shares of Common Stock that WPV, WPV, Inc. or any of their affiliates may in the future acquire from the Company or in the open market. In Page 10 of 17 Pages connection with the closing under the Stock Purchase Agreement, the Registration Rights Agreement was further amended by execution of an Amendment No. 2 to the Registration Rights Agreement (the "Registration Rights Amendment No. 2") to provide registration rights with respect to the Purchased Shares. The foregoing summary of the Registration Rights Agreement, the Registration Rights Agreement Amendment is qualified in its entirety by reference to the Registration Rights Agreement, which is incorporated herein by reference to Exhibit 4.2 to the Company's Form 10-K for the fiscal year ended December 31, 1999, filed with the Commission on March 23, 2000, by reference to the Registration Rights Agreement Amendment, which is incorporated herein by reference to Exhibit 4.4 to the Form 8-K filed by the Company with the Commission on March 12, 2001, and by reference to the Registration Rights Amendment No. 2, which is incorporated herein by reference to Exhibit 4.4 to the Company's Form 8-K, filed with the Commission on December 7, 2001. Except as referred to above, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 or between such persons and any other person with respect to any securities of the Company."
