The Schedule 13D originally filed on October 4, 1999 on behalf of UtiliCorp and nineteen amendments thereto filed on October 8, 1999, October 14, 1999, October 20, 1999, October 26, 1999, November 9, 1999, January 13, 2000, April 27, 2000, May 25, 2000, June 20, 2000, July 17, 2000, May 23, 2001, October 1, 2001, October 4, 2001, October 11, 2001, October 19, 2001, October 30, 2001, November 13, 2001, and November 28, 2001, respectively, on behalf of UtiliCorp are incorporated by reference and amended as follows. ITEM 4. PURPOSE OF TRANSACTION. As previously disclosed in amendments to this Schedule 13D, UtiliCorp has been engaged for several months in discussions with Quanta concerning UtiliCorp's desire to elect a majority of the directors to Quanta's board in order to achieve financial statement consolidation for financial reporting purposes with respect to Quanta. These discussions were recently abandoned for a second time. During the course of these protracted negotiations, Quanta's board of directors authorized actions that UtiliCorp believes violated an agreement between UtiliCorp and Quanta concerning UtiliCorp's right to purchase Quanta's stock. These actions, together with Quanta's disappointing financial performance, have caused UtiliCorp to re-evaluate its prior support of Quanta's current board of directors. Accordingly, UtiliCorp has advised Quanta that it intends to present an opposition slate of nominees for election as directors at Quanta's 2002 annual meeting of stockholders. UtiliCorp's slate will be named within the time period required by Quanta's bylaws and will consist of six individuals that are affiliated with UtiliCorp and three that are independent from both UtiliCorp and Quanta. The UtiliCorp-nominated slate of directors is expected to exhibit and promote business objectives, goals, and values that are reflective of those of UtiliCorp. If elected, UtiliCorp's nominees are expected to implement a long-term business plan aimed at maximizing the value of Quanta. In addition, UtiliCorp may pursue short-term initiatives designed to bring significant value to Quanta's stockholders. For instance, UtiliCorp is contemplating, subject to price and other considerations, the implementation of a stock repurchase program in the range of 20% to 25% of Quanta's outstanding shares. The repurchase program could take the form of a third-party or an issuer self-tender offer. Alternatively, upon obtaining control of the Quanta board, UtiliCorp may initiate a sale process for Quanta (in which UtiliCorp may or may not be a participant) or may consider appropriate unsolicited offers to acquire Quanta. UtiliCorp intends to canvass other stockholders of Quanta in order to assess their views concerning the strategic direction of Quanta. The input of these stockholders will be considered by UtiliCorp in formulating its definitive plans and proposals to maximize the value of Quanta. To assist UtiliCorp in formalizing the strategy that will guide the UtiliCorp director nominees to Quanta's board, UtiliCorp is currently in the process of retaining an investment banking firm to act as a financial advisor. Notwithstanding UtiliCorp's misgivings about the actions recently taken by Quanta's board and the overall performance of Quanta's management team as reflected in Quanta's recent financial performance, UtiliCorp continues to believe that certain of Quanta's existing management and employees 4 are important to its future. Accordingly, if UtiliCorp's nominees are elected at Quanta's 2002 annual meeting of stockholders, they are expected to support a broad-based retention program directed at Quanta's key employees, including certain executive management employees. 5 SIGNATURE After reasonable inquiry and to the best of the undersigned's knowledge and belief, the undersigned hereby certifies that the information set forth in this statement is true, complete and correct.
