*    February 2002:

     o    Parties attempt to negotiate but Aquila walks away when accounting
          advice changes

     o    Aquila launches proxy fight; nearly 50% of projected 2002 earnings

          consolidation is a goal when accounting is challenged

          offering benefits or protections for other stockholders

                           IV. PERSPECTIVE ON AQUILA






AQUILA STOCKHOLDER ABUSE
--------------------------------------------------------------------------------

*      Aquila has a legacy of promoting their own interests at the expense of
       minority shareholders' rights

        o April 1999: Aquila squeezes out the minority in its controlled
          subsidiary, Aquila Gas Pipeline (AGP) at a low price and over the
          objections of a special committee of AGP directors

                o Sell to shareholders at $15.00 and buy back at $8.00 (1)

                              RESULT: 47% DISCOUNT

        o January 2002: Without bothering to install independent directors to
          approve the transaction, Aquila squeezes out minority stockholders in
          its highest growth subsidiary to take advantage of a weak market.
          Aquila was sued by minority investors

                o Sell to shareholders at $24.00 and buy back at $18.21  (24%)

                              RESULT: 24% DISCOUNT


1 Excludes dividends with a present value of $0.32 as of the squeeze-out date.

AQUILA'S LACKLUSTER PERFORMANCE
--------------------------------------------------------------------------------

*       On April 19, 2002, Aquila announced that it expects its first quarter
        earnings to fall 54% from 2001 levels

*      Aquila shares lost 19% of their value in 2001 and have further declined
       9% through April 19, 2002

*      Aquila recently was downgraded by Fitch rating service to BBB-, just
       above junk bond status

*      Aquila is engaged in a dispute with Chubb over their agreement to
       collateralize $570 million worth of surety bonds

*      In spite of lackluster performance the Green brothers rewarded themselves
       handsomely

         o  Their average bonus increase from 2000-2001 was 40%

31




AQUILA'S "PROGRAM FOR ENHANCING VALUE"
--------------------------------------------------------------------------------

*      Committed to exploring a sale of the company
        o  The existing Board of Directors is committed to evaluating all
           alternatives

        o  Aquila has been an obstruction to Quanta operations and the Board's
           efforts to explore a full range of strategic alternatives for the
           company

*      Joint Self Tender/Aquila Tender offer for shares
        o  Aquila is trying to take control of Quanta using Quanta's own balance
           sheet and without offering a premium for Quanta's shares or any solid
           protections for minority shareholders

        o  They would limit the company's financial flexibility and capacity to
           complete continued strategic acquisitions

*      Seek strategic investors to advance the strategy
        o  Again, an alternative the Board is currently pursuing, in spite of
           Aquila's obstruction

        o  Aquila is proposing the right to reserve flexibility for it to sell
           its control stake to such strategic investors without regard for the
           implications to other shareholders

        o  Not clear that Aquila's "independent directors: would have any say on
           squeeze-outs (ala AGP and "Old Aquila") or on sale by Aquila of its
           control block

RECENT QUANTA BOARD INITIATIVES
--------------------------------------------------------------------------------
*      Approved creation of a Stock Employee Compensation Trust ("SECT") with 8
       million shares of common stock in the trust to fund a significant portion
       of the Company's employee benefit obligations during the next 15 years

*      Standardized employment agreements  for certain corporate and operating
       unit employees
        o  Aimed at ensuring an "in place" management team

        o  Stabilize the Company's most vital assets

*      Amended Quanta's stockholder rights plan to render the rights
       inapplicable to any offer for all Quanta shares that is accepted by 75%
       of the stockholders
        o  "Chewable pill" continues to protect Quanta investors against partial
           or creeping takeover efforts, but would not stand in the way of any
           serious equitable offer

*      Authorized financial advisor, Goldman Sachs, to explore a range of
       strategic options, including acquisitions, stock repurchase,
       recapitalization and extraordinary transactions
        o  Any transaction would be structured so as to preclude Aquila from
           achieving control without offering value and protections to Quanta
           stockholders

RECENT QUANTA BOARD INITIATIVES - SECT
--------------------------------------------------------------------------------

*      Provides greater financial flexibility by reducing the Company's cash
       obligations to fund employee benefit programs

*      Increases equity base by 9%; not counted for EPS until shares released;
       modest voting dilution

*      Credit agencies give companies partial equity credit for Trust shares -
       "strong equity characteristics"

*      Many companies have similar programs, including American Express, DuPont,
       Pfizer, Conrail, Tenneco and Corning

*      Trust acquired common stock from Quanta primarily in exchange for a
       promissory note equal to the market value of the stock being sold

*      Underscores management's belief in stock and commitment to stock-based
       compensation and incentives

*      Shares in Trust voted confidentially by a broad based group (over 2000)
       of employees, not including employees who are directors
