WE NEED YOUR VOTE. PLEASE VOTE THE WHITE CARD WE HAVE PREVIOUSLY SENT YOU TODAY to stop Aquila from taking control of Quanta and your investment without offering you anything in return. If you have not yet voted your shares or have voted for Aquila's nominees and would like to change your vote, PLEASE CALL MACKENZIE PARTNERS toll-free at 800-322-2885. They can help you with any information you may need to VOTE THE WHITE CARD. ISS, THE LEADING PROXY ADVISOR TO MAJOR FINANCIAL INSTITUTIONS, RECOMMENDS THAT INVESTORS VOTE FOR QUANTA'S NOMINEES We urge you to consider what ISS told its institutional clients in its May 16, 2002 report supporting Quanta's existing Board, and we quote (1): >> "[I]t appears that Aquila is not offering anything new to shareholders" >> "Given the fact that Aquila is seeking a change in control with no immediate premium to shareholders, ISS is not convinced that this is the best course of action for Quanta's shareholders." >> "Arguably, the poison pill is protecting shareholders from a potential Aquila transaction that offers nothing new, other than a potential repurchase program designed to acquire up to 20 to 25 percent of the shares outstanding, which would ultimately give control of the company to Aquila." >> "Aquila's track record raises some questions regarding the fact that minority shareholders of Aquila subsidiaries got bought out at a discount to the original sale price in a going-private transaction. The possibility of a coercive or two-tiered offer would be the worst case scenario for Quanta's shareholders." >> "While implementing the SECT [Stock Employee Compensation Trust] and establishing a 39 percent limit on Aquila's ownership of Quanta give the appearance of an effort to block Aquila from acquiring the company, ISS believes that Quanta is protecting its shareholders in the process." >> "Given the company's overall performance, ISS believes that Quanta has a feasible strategic plan in place to maximize shareholder value." QUANTA IS PERFORMING WELL IN A CHALLENGING ENVIRONMENT Contrary to Aquila's disingenuous assertions and under the leadership of its current Board of Directors, Quanta is performing well and outpacing its peers in a challenging environment. o On May 8, 2002, Quanta announced its first quarter results, which included revenues of $449.2 million and operating cash flow of $68.4 million. o These results follow Quanta's strong performance in 2001 when it generated record revenues, concluding a three-year period of revenue growth that outpaced its peers, and record cash flow. QUANTA'S NOMINEES ARE FOCUSED ON ENHANCING STOCKHOLDER VALUE As previously announced, Quanta's Board is committed to enhancing stockholder value and has authorized its financial advisor to evaluate all options, including a potential sale of the Company, to which Aquila has been an impediment in the past. QUANTA'S NOMINEES ARE: o Responsible for and still personally supervise almost $700 million, or approximately 34.7% of Quanta's 2001 revenues; o Owners of 5.27% of Quanta's stock; and o Very knowledgeable about our business, with 84 years of aggregate or direct operating experience. AQUILA'S NOMINEES: o Are pledged to Aquila's self-serving agenda; o Own very little Quanta stock; o Have virtually no operating experience in our business; and o Have no concrete plan to generate value for Quanta stockholders. ON MAY 15, AQUILA WAS PLACED ON S&P'S "CREDIT CLIFF" MEANING IT IS VULNERABLE TO A LIQUIDITY CRISIS IF ITS DEBT IS DOWNGRADED. (2) As we have described to you in past letters, Aquila has been performing poorly and it has a history of abusing minority stockholders to pursue its own financial interests. Stockholders have twice suffered steep losses as a result of Aquila's squeeze-out transactions. DON'T LET THIS HAPPEN TO YOU. DON'T LET AQUILA STEAL QUANTA. ELECT QUANTA'S NOMINEES TODAY. Very truly yours, By: /s/ Vincent D. Foster By: /s/ John R. Colson Vincent D. Foster John R.
