                    SECOND AMENDED CLASS ACTION PETITION
                    ------------------------------------

          Plaintiff  alleges  upon  information  and  belief,   except  for
paragraph 1 hereof, which is alleged upon knowledge, as follows:

          1.  Plaintiff has been the owner of shares of the common stock of
Aquila,  Inc.  ("Aquila" or the "Company") since prior to the wrongs herein
complained of and continuously to date.

          2. Aquila is a corporation  that maintains its principal  offices
at 1100 Walnut Street,  Suite 3300, Kansas City, MO 64106. The Company is a
wholesale  energy  risk  merchant  that  markets  and  trades   commodities
including natural gas, electricity,  weather, coal, bandwidth capacity, and
emission allowances.

          3.  Defendant  UtiliCorp  United,  Inc.   ("UtiliCorp")  owns  or
controls  approximately  80% of the Class A shares  and 100% of the Class B
shares of the Company's common stock,  giving it 98% of the combined voting
power of the Company.

          4.  Defendant  Richard  K.  Green  is  Chairman  of the  Board of
Directors  of the  Company and  President  and Chief  Operating  Officer of
UtiliCorp.

          5.  Defendant  Keith G. Stamm is Chief  Executive  Officer  and a
Director of the Company and Senior Vice President of UtiliCorp.

          6. Defendant  Richard C. Green, Jr., is a Director of the Company
and Chairman and Chief Executive of UtiliCorp.

          7.  UtiliCorp,  as  controlling  shareholder,  and  the  director
defendants stand in a fiduciary  position  relative to the Company's public
shareholders  and owe the public  shareholders of Aquila the highest duties
of good  faith,  fair  dealing,  due  care,  loyalty,  and full and  candid
disclosure.

                          CLASS ACTION ALLEGATIONS
                          ------------------------

          8.  Plaintiff  brings this action as a class action,  pursuant to
Rule 23 of the  Rules of the  Circuit  Court,  on  behalf  of all  security
holders of the Company (except the defendants herein and any person,  firm,
trust,  corporation,  or other entity related to or affiliated  with any of
the  defendants)  and  their  successors  in  interest,  who are or will be
threatened  with  injury  arising  from  defendants'  actions as more fully
described herein.

          9. This action is properly maintainable as a class action.

          10.  The class is so  numerous  that  joinder  of all  members is
impracticable.  There are  approximately  19.975  million  shares of Aquila
Class A common stock  outstanding owned by hundreds,  if not thousands,  of
holders other than UtiliCorp and it affiliates.

          11.  There are  questions of law and fact which are common to the
class  including,  inter alia, the following:  (a) whether  defendants have
breached  their  fiduciary  and other  common  law  duties  owed by them to
plaintiff and the members of the class; (b) whether defendants are pursuing
a scheme and course of business designed to eliminate the public securities
holders  of Aquila in  violation  of the laws of the State of  Missouri  in
order to enrich  UtiliCorp at the expense and to the detriment of plaintiff
and the other public stockholders who are members of the class; (c) whether
the proposed transaction,  hereinafter  described,  constitutes a breach of
the duty of fair  dealing  with  respect  to the  plaintiff  and the  other
members of the class;  and (d) whether the class is entitled to  injunctive
relief  or  damages  as a  result  of the  wrongful  conduct  committed  by
defendants.

          12.  Plaintiff is committed  to  prosecuting  this action and has
retained  competent counsel  experienced in litigation of this nature.  The
claims of the  plaintiff  are typical of the claims of other members of the
class and  plaintiff  has the same  interests  as the other  members of the
class. Plaintiff will fairly and adequately represent the class.

          13. Defendants have acted in a manner which affects plaintiff and
all  members of the class  alike,  thereby  making  appropriate  injunctive
relief and/or corresponding declaratory relief with respect to the class as
a whole.

          14. The prosecution of separate actions by individual  members of
the Class would create a risk of inconsistent or varying adjudications with
respect  to  individual   members  of  the  Class,  which  would  establish
incompatible  standards of conduct for defendants,  or  adjudications  with
respect to  individual  members of the Class  which  would,  as a practical
matter,  be dispositive of the interests of other members or  substantially
impair or impede their ability to protect their interests.

                          SUBSTANTIVE ALLEGATIONS
                          -----------------------

          15. On April 23, 2001 the Company sold 17.5 million shares of its
Class A common stock in an initial public offering at a price of $24.00 per
share (the "IPO"). After the IPO, Aquila shares were listed on the New York
Stock  Exchange  ("NYSE")  under the symbol  "ILA." In the IPO  prospectus,
UtiliCorp  stated that it intended to spin off the remaining  Aquila shares
within the 12 months following the IPO.

          16. Since the time of the IPO, the Individual Defendants, who are
also officers  and/or  directors of UtiliCorp,  have  constituted  Aquila's
Board of Directors.  NYSE Rules  require that a company  traded on the NYSE
appoint at least two  independent  directors to its Board within 90 days of
its initial public offering. To date, Defendants have violated and continue
to violate  NYSE Rules by failing to appoint any  independent  directors to
the Aquila Board.  Defendants refusal to appoint any independent  directors
to the Aquila Board ensures that the UtiliCorp defendants retain unfettered
discretion in their dealings with Aquila and its public shareholders.

          17. On November 7, 2001,  UtiliCorp  announced that it had made a
proposal  to acquire  all of the shares of common  stock of the Company not
held by  UtiliCorp  and its  affiliates.  Under the terms of the  UtiliCorp
proposal,  the Company's public  shareholders will receive 0.6896 shares of
UtiliCorp common stock for each share  outstanding  share of Aquila Class A
common stock (the "Exchange  Offer").  The Exchange Offer is subject to the
condition  that a majority  of the  outstanding  shares  held by the public
shareholders tender their shares. If this condition is satisfied, UtiliCorp
intends to acquire  the  remaining  shares in a short form merger that does
not require the consent of Aquila's public shareholders.

          18. The Exchange Offer contemplates a fixed exchange ratio; there
is no "collar" or other mechanism to protect Aquila shareholders  against a
decline in the price of UtiliCorp stock.

          19. At the time the Exchange Offer was announced and based on the
November 6, 2001  closing  price of $30.00 per share for  UtiliCorp  stock,
each Aquila Class A share was valued at approximately $20.69, significantly
below the IPO price and wholly inadequate consideration.

          20. However,  since the  announcement of the Exchange Offer,  the
price of UtiliCorp stock has declined  significantly,  closing at $25.62 on
December 4, 2001. As a result, the consideration  Aquila  shareholders will
receive has fallen to approximately  $17.67 per share, nearly 27% below the
IPO price.

          21. The  Exchange  Offer is coercive  because it contains a fixed
exchange  ratio  that  has not and  will not  protect  Aquila  shareholders
against  a decline  in the  price of  UtiliCorp's  stock.  Aquila's  public
shareholders  are compelled to tender their shares in the Exchange Offer or
risk receiving  UtiliCorp stock worth  significantly less in the short form
merger in the event of a severe decline in UtiliCorp's stock price.

          22. At a minimum,  Aquila  shareholders  who do not tender in the
Exchange Offer should be guaranteed to receive  minimum  consideration  for
their shares  having at least the value of the Exchange  Offer  ($20.69 per
share) on the day the Exchange Offer was announced.  Absent this condition,
Aquila  shareholders  will not be able to consider the Exchange Offer in an
atmosphere free from coercion.

          23.  Moreover,  because  defendants  have  refused to appoint any
independent  directors to the Aquila Board (in violation of NYSE Rules), it
is not  possible to form a special  committee of  independent  directors to
negotiate  on  behalf  of,  or at  least  opine as to the  adequacy  of the
Exchange Offer to Aquila's public shareholders.  Absent the protection of a
special committee,  the Company's public shareholders are unable to make an
informed  decision  as to whether to tender in the  Exchange  Offer or not.
Accordingly, defendants should be compelled to immediately appoint at least
two independent directors to the Aquila Board.

          24. On December 3, 2001, UtiliCorp filed a Registration Statement
on Form S-4 (the "Registration  Statement") in connection with the Exchange
Offer. The Registration Statement contained the terms of the Exchange Offer
as well as other purportedly  relevant information about the two companies.
However,  the  Registration   Statement,   which  was  not  vetted  by  any
disinterested  persons, fails to disclose material information about Aquila
and UtiliCorp.

          25. The Registration  Statement contains financial  forecasts for
both UtiliCorp and Aquila.  However,  the Aquila forecasts were prepared by
UtiliCorp  management  and not by the  management  of  Aquila.  In light of
UtiliCorp's conflicts with Aquila shareholders,  these forecasts are highly
suspect and cannot be relied on by Aquila shareholders.

          26. Moreover,  the Registration Statement only provides a cursory
summary of the Company's projected financial results for 2001 and 2002. The
Registration  Statement  merely states  "beyond 2002, we target 25% average
annual  growth for  Aquila."  No  meaningful  or  detailed  information  is
provided to the Company's public  shareholders  concerning  Aquila's growth
beyond 2002.  Similarly,  the Registration  Statement only provides cursory
summary   financial   forecasts  for  UtiliCorp  for  2001  and  2002.  The
Registration  Statement also notes that "beyond 2002, we target 15% average
annual growth for  UtiliCorp."  No meaningful  or detailed  information  is
provided to the Company's public shareholders concerning UtiliCorp's growth
beyond  2002.  This  information  is  vital  to  the  ability  of  Aquila's
shareholders to properly evaluate the Exchange Offer.

          27. The Registration  Statement discloses that UtiliCorp retained
Lehman Brothers,  Inc. ("Lehman") to serve as its financial adviser in this
transaction.  However, the Registration Statement is silent with respect to
the   valuation   analyses   performed  by  Lehman.   Accordingly,   Aquila
shareholders cannot determine from these materials what the intrinsic value
of the Aquila  shares is and why the proposed  acquisition  by UtiliCorp is
preferable to other alternatives or is fair.

          28. Moreover,  the UtiliCorp defendants,  in breach of NYSE Rules
and their fiduciary duties,  have refused to appoint any independent Aquila
directors who would be in a position to retain their own financial advisors
and otherwise protect Aquila's public shareholders.  Accordingly, UtiliCorp
should  be  compelled  to  disclose  the  various  valuation  methodologies
employed by Lehman and the results of those valuation analyses.

          29.  Since the  Company  went  public in April 2001 at $24.00 per
share, its stock has traded as high as $35.00 per share.  However, due to a
temporary  downturn in Aquila's market and in general economic  conditions,
Aquila's  stock price has declined.  In breach of its  fiduciary  duties as
controlling  shareholder,  UtiliCorp  has timed the Exchange  Offer to take
advantage  of  this  temporary   downturn  to  eliminate   Aquila's  public
shareholders for inadequate  consideration.  It is clear that UtiliCorp has
timed the transaction to buy Aquila on the cheap because  UtiliCorp  itself
projects earnings per share growth of 25% for Aquila beyond 2002.

          30. The consideration to be paid to class members,  now valued at
$17.67 per share,  is unfair and inadequate  consideration  because,  among
other things:  (a) the intrinsic value of the stock of Aquila is materially
in excess of $17.67 per share,  giving due  consideration  to the prospects
for growth and profitability of Aquila  (particularly beyond 2002) in light
of its business,  earnings and earnings power,  present and future; (b) the
$17.67  per  share  price  offers  an  inadequate  premium  to  the  public
stockholders of Aquila and is well below the April 23, 2001 IPO price;  and
(c)  the  $17.67  per  share  price  is not  the  result  of  arm's  length
negotiations  but was fixed  arbitrarily  by  UtiliCorp to "cap" the market
price of Aquila stock,  as part of a plan for UtiliCorp to obtain  complete
ownership  of  Aquila,  its assets and  businesses  at the lowest  possible
price.

          31.  The   proposal  is  an  attempt  by  UtiliCorp  to  unfairly
aggrandize  UtiliCorp at the expense of Aquila's public  stockholders.  The
proposal will, for inadequate  consideration,  deny plaintiff and the other
members of the class  their  right to share  proportionately  in the future
success of Aquila and its valuable assets,  while  permitting  UtiliCorp to
benefit wrongfully from the transaction.

          32. Given the UtiliCorp defendants' stock ownership in Aquila and
the fact that all of the Directors are also  officers  and/or  directors of
UtiliCorp,  none  of  the  directors  will  protect  the  Company's  public
shareholders  in  transactions  which  benefit  UtiliCorp at the expense of
Aquila's public shareholders, as exemplified by the Exchange Offer.

          33. Because of UtiliCorp's  stock  ownership and the offices held
by UtiliCorp personnel,  no third party, as a practical matter, can attempt
any competing bid for Aquila,  as the success of any such bid would require
the  consent  and  cooperation  of  the  UtiliCorp  defendants.   Moreover,
UtiliCorp has  indicated  that it will not sell its shares to a third party
nor spin off the rest of Aquila to the public.

          30.  Plaintiff  and the other  members of the Class  will  suffer
irreparable  damage unless  defendants  are enjoined from  breaching  their
fiduciary duties to Aquila's public shareholders in a proposed  transaction
which will benefit fiduciaries at the expense of the public shareholders of
the Company.

          31. Plaintiff and the other members of the Class have no adequate
remedy at law.

          WHEREFORE, plaintiff demands judgment against defendants, jointly
and severally, as follows:

          (1)  declaring  this action to be a class  action and  certifying
plaintiff  as the Class  representative  and  plaintiff's  counsel as Class
counsel;

          (2) enjoining,  preliminarily  and  permanently,  the transaction
complained of herein;

          (3)  ordering  defendants  to  appoint  at least two  independent
directors to the Aquila  Board and to disclose  all  relevant  information,
including detailed  projections and a description of the financial analyses
performed by Lehman;

          (4) ordering defendants to guarantee that Aquila shareholders who
do not tender  will  receive  consideration  having a minimum  value of the
Exchange Offer on the date the transaction was announced;

          (5) the value of to the extent,  if any, that the  transaction or
transactions  complained  of are  consummated  prior  to the  entry of this
Court's final judgment,  rescinding such  transaction or  transactions,  or
granting the Class rescissory damages;

          (6) directing that defendants  account to plaintiff and the other
members of the Class for all  damages  caused to them and  account  for all
profits and any  special  benefits  obtained as a result of their  unlawful
conduct;

          (7)  awarding  plaintiff  the  costs  and  disbursements  of this
action,  including  a  reasonable  allowance  for the fees and  expenses of
plaintiff's attorneys and experts; and

          (8) Granting  plaintiff  and the other  members of the Class such
other and further relief as may be just and proper.
