INTRODUCTION

         UtiliCorp  United Inc., a Delaware  corporation  ("UtiliCorp"),  hereby
files  this  Statement  on  Schedule  13D (the  "Statement")  on  behalf  of the
Reporting  Persons  identified in Item 2 below  pursuant to the  Agreement  With
Respect to Schedule 13D attached hereto as an Exhibit.

ITEM 1.  SECURITY AND ISSUER.

         This  Statement on Schedule 13D relates to the shares of common  stock,
par value $0.00001 per share, of Quanta Services,  Inc., a Delaware  corporation
("Issuer")  (the  "Common  Stock"),  issuable  on  conversion  of the  Series  A
convertible  preferred  stock,  par value  $0.00001  per  share,  of the  Issuer
("Convertible  Preferred  Stock")  and shares of Common  Stock  acquired in open
market and privately  negotiated  purchases.  The principal executive offices of
the Issuer are located at 1360 Post Oak Boulevard,  Suite 2100,  Houston,  Texas
77056.

ITEM 2.  IDENTITY AND BACKGROUND.

         This   Statement  is  filed  by  UtiliCorp   United  Inc.,  a  Delaware
corporation  ("UtiliCorp"),  and Robert K. Green,  President and Chief Operating
Officer of UtiliCorp (collectively, the "Reporting Persons").

         UtiliCorp  is a publicly  held  company  (trading  symbol  "UCU") whose
executive  offices are located at 20 West Ninth  Street,  Kansas City,  Missouri
64105, and its telephone number is (816) 421-6600.  UtiliCorp is a multinational
energy and energy services business with regulated  utility  operations in seven
states within the United States and energy operations in New Zealand, Australia,
the United  Kingdom and Canada.  UtiliCorp  also owns  non-utility  subsidiaries
involved   in  energy   trading,   natural   gas   gathering,   processing   and
transportation,  energy efficiency  services,  and various other  energy-related
businesses.

         Robert K. Green,  a United  States  citizen,  resides at 2318 West 59th
Street,  Mission Hills, Kansas 66208. Mr. Green is President and Chief Operating
Officer of UtiliCorp,  which  maintains  its  executive  offices at the location
described above.

         During  the  last  five  years,  the  Reporting  Persons  have not been
convicted in a criminal  proceeding  (excluding  traffic  violations  or similar
misdemeanors)  and have not been party to a civil  proceeding  of a judicial  or
administrative  body  of a  competent  jurisdiction  and  as a  result  of  such
proceeding was or are subject to a judgment,  decree,  or final order  enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violations with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Pursuant to a Securities  Purchase  Agreement  dated September 21, 1999
("Closing  Date")  between  UtiliCorp  and the  Issuer  ("Purchase  Agreement"),
UtiliCorp  purchased from the Issuer 1,860,000  shares of Convertible  Preferred
Stock in the aggregate principal amount of $186,000,000  ("Purchase Price"). The
Convertible  Preferred  Stock is convertible  into Common Stock at the option of
UtiliCorp.  UtiliCorp  purchased  the  Convertible  Preferred  Stock  with funds
obtained pursuant to a Credit Agreement among UtiliCorp and numerous banks (with
CitiBank, N.A. as agent).

         Between September 2, 1999 and September 29, 1999,  UtiliCorp  purchased
in  a   series   of   broker-assisted   purchases   on  the  open   market   and
privately-negotiated  purchases  1,933,685 shares of Common

Stock. The aggregate  funding required for these purchases was $50,462,110,  all
of which was funded by a Credit  Agreement  among  UtiliCorp and numerous  banks
(with CitiBank, N.A. as agent). 1

         On June 30,  1999  Robert  Green  purchased  10,000  shares of Issuer's
outstanding  common stock on the open market for an aggregate  purchase price of
$390,000 with personal funds.

ITEM 4.  PURPOSE OF THE TRANSACTION.

         The purchase of the  Convertible  Preferred Stock of the Issuer was the
result of a  negotiated  transaction  with the Issuer,  and it was  acquired for
investment purposes. UtiliCorp intends to review its investment in the Issuer on
a continuing basis and,  depending upon the price of and other market conditions
relating to the Convertible Preferred Stock,  subsequent  developments affecting
the Issuer,  the Issuer's business and prospects,  other investment and business
opportunities available to UtiliCorp and its affiliations,  general stock market
and economic  conditions,  tax considerations and other factors deemed relevant,
may decide to increase or decrease the size of its investment in the Issuer.

         UtiliCorp's  open market  purchases of Common Stock were undertaken for
investment purposes as described in the preceding paragraph.  UtiliCorp has also
purchased shares of Common Stock by, as of September 29, 1999,  contracting with
21 of the Issuer's record  stockholders  for the purchase of 1,069,485 shares of
Common Stock for an aggregate purchase price of $27,806,610.2

         Robert Green purchased 10,000 shares of Common Stock on the open market
for an  aggregate  purchase  price of  $390,000,  such  purchases  were made for
investment purposes.

         In addition to the Purchase  Agreement,  the  following  documents  (as
described  herein),  which  were  conditions  precedent  to the  signing  of the
Purchase  Agreement,  are attached as exhibits to this Schedule and incorporated
herein  by  reference:   Stockholder's  Voting  Agreements  (the  "Stockholder's
Agreements"),  Strategic Alliance  Agreement,  Investor's Rights Agreement,  Fee
Letter Agreement, and Certificate of Designation, Rights, and Limitations of the
Series A Convertible Preferred Stock of Quanta Services,  Inc. (the "Certificate
of  Designation").  The following  summaries of the terms of such agreements are
qualified by reference to the actual agreements.

         Purchase Agreement. On September 21, 1999, UtiliCorp and Issuer entered
into the  Purchase  Agreement  which  provided  for the purchase by UtiliCorp of
Convertible Preferred Stock in the aggregate amount of $186,000,000.  The number
of shares of Common Stock issuable upon conversion of the Convertible  Preferred
Stock by  UtiliCorp  will be  determined  by dividing the price per share of the
Convertible  Preferred  Stock  (i.e.,  $100) by the  conversion  price of $30.00
(subject  to  adjustment  for  any  stock  split,  combination,  and  the  like)
("Conversion  Price"),  approximately  6,200,000  shares of Common Stock,  on an
as-converted  basis,  at the  Closing  Date.  The  Purchase  Agreement  includes
provisions  customary  in  commercial  investments,  including,  for purposes of
illustration only, inclusion of an anti-hedging provision (i.e., for a period of
10 years, UtiliCorp shall not engage in transactions intended to reduce its risk
of owning the Common Stock).

         Stockholder's  Agreements.  The  irrevocable  Stockholder's  Agreements
among UtiliCorp,  Issuer, and various  stockholders  owning shares of the Common
Stock of the Issuer  (cumulatively,

                                  Page 5 of 9


<PAGE>

the "Stockholders"), dated September 21, 1999, obligate the Stockholders to vote
all  shares  of Common  Stock  owned by them,  or over  which  they have  voting
control,  to approve the following  proposals:  (i) any proposal  recommended by
Issuer's  Board of Directors  for the purpose of enabling  UtiliCorp to exit its
investment  in the Issuer in the most tax  efficient  manner;  (ii) any proposal
recommended by Issuer's Board of Directors for the purpose of allowing UtiliCorp
to hold  shares of the Issuer in the most tax  efficient  manner;  and (iii) any
ancillary  proposals  that  are  necessary  or  appropriate  to  effectuate  the
foregoing proposals.  The Stockholder's  Agreements  terminate  automatically if
UtiliCorp's  Fully Diluted  Ownership  Ratio (as defined in the  Certificate  of
Designation)  is less  than 5%,  and  with  respect  to  shares  subject  to the
Stockholder's  Agreements that are subsequently  sold by the  Stockholders,  the
Stockholder's Agreements cease to apply to such shares upon sale.

         Strategic  Alliance  Agreement.  On September  21, 1999,  UtiliCorp and
Issuer  entered into the Strategic  Alliance  Agreement  which provides that the
Issuer is  UtiliCorp's  preferred  contractor  in  outsourced  transmission  and
distribution   infrastructure  construction  and  maintenance  and  natural  gas
distribution  construction  and  maintenance in all areas serviced by UtiliCorp,
provided that the Issuer  provides  such services at a competitive  cost that is
demonstrably equal to or better than current market rates for such services. The
Strategic  Alliance  Agreement  terminates  six  years  from the  Closing  Date,
although the parties thereto may engage in business  relations with  competitors
of the other party and its affiliates  during such time.  Neither  UtiliCorp nor
the Issuer owe the other party any fiduciary duties (in fact, no relationship of
whatever  kind or  form  exists)  under  the  terms  of the  Strategic  Alliance
Agreement.

         Fee Letter  Agreement.  Signed on September 21, 1999 between the Issuer
and UtiliCorp, the Fee Letter Agreement entitles UtiliCorp to receive $3,720,000
for advisory services performed by UtiliCorp.

         Investor's  Rights  Agreement.  On September  21, 1999,  UtiliCorp  and
Issuer entered into the Investor's Rights Agreement which provides,  among other
things,  that UtiliCorp is entitled to (i) one demand  registration with respect
to the Common Stock into which the  Convertible  Preferred Stock is convertible;
(ii)  unlimited  "piggyback"  registrations;  and (iii) a  pre-emptive  right to
purchase  shares of common  stock of the Issuer  upon the  Issuer's  issuance of
shares to third  parties.  The Investor  Rights  Agreement  also  provides  that
UtiliCorp shall not transfer any portion of its shares of Convertible  Preferred
Stock to any competitor of the Issuer.

         Certificate  of  Designation.  Executed  and  filed  with the  Delaware
Secretary of State's Office on September 21, 1999 by the Issuer, the Certificate
of Designation  designates  1,860,000 shares of the Issuer's  preferred stock as
Series A Convertible Preferred Stock and sets forth the terms of the Convertible
Preferred  Stock.  The  Certificate  of  Designation  provides that UtiliCorp is
entitled to nominate and elect two directors to the Issuer's Board of Directors;
provided, however, (i) UtiliCorp may nominate a third director if it owns 30% or
more of the  outstanding  shares of the Issuer on a fully  diluted  basis,  (ii)
UtiliCorp  will only be  entitled  to  nominate  and elect one  director  to the
Issuer's  Board of  Directors if it disposes of at least 50%, but less than 75%,
of the total number of common stock into which the  Convertible  Preferred Stock
is then convertible,  on a fully diluted basis, and (iii) UtiliCorp shall not be
entitled to elect any  directors to the Issuer's  Board of Directors if it sells
75% or more of the  total  number  of shares  of  Common  Stock  into  which the
Convertible  Preferred Stock is then convertible,  on a fully diluted basis. The
Certificate  of Designation  also provides  that,  for purposes of  illustration
only, (i) the  Convertible  Preferred  Stock is convertible at the discretion of
UtiliCorp  without  expiration,  except that the Issuer is entitled to terminate
any obligation to pay the  participating,  preferred  dividends beyond the sixth
anniversary from the date hereunder if the Common Stock of the Issuer is trading
in the open market above the  Conversion  Price at that time; and (ii) UtiliCorp
shall have that  number of votes  equal to the number of shares of Common  Stock
into which the  Convertible  Preferred  Stock is convertible at the  appropriate
record date.

                                     6 of 9


<PAGE>

         In addition,  the  Certificate  of  Designation  entitles  UtiliCorp to
receive cash dividends,  which are cumulative,  at the rate of 0.5% per annum on
the Purchase Price of the Convertible  Preferred Stock  ("Preferred  Dividend");
provided,  however,  that the Issuer may in its sole  discretion  terminate  the
Preferred  Dividend at any time after the sixth  anniversary of the Closing Date
if the  closing  price of the  Common  Stock is  greater  than  $30.00 per share
(subject to adjustment for any stock split, combination, and the like).

         Other than the transactions described herein, the Reporting Persons nor
any of their  affiliates  have any plan or proposal  that would result in any of
the consequences listed in paragraphs (a)-(j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         UtiliCorp   beneficially  owns  1,860,000  shares  of  the  Convertible
Preferred  Stock at September  21, 1999,  representing  100% of the  outstanding
class as of that date. On an as-converted basis, the Convertible Preferred Stock
beneficially  owned by  UtiliCorp  pursuant  to the  Purchase  Agreement  equals
approximately   6,200,0003   shares  of  Common  Stock  at  September  21,  1999
representing 19.6%4 of the outstanding Common Stock at that date. UtiliCorp also
beneficially  owns  1,933,685  shares of the  issued and  outstanding  shares of
Common  Stock,  acquired by  UtiliCorp  in  privately-negotiated  or open market
purchases5.  The  aggregate  amount  of the  stock  described  in the  preceding
sentence  represents 6.1% of the issued and  outstanding  Common Stock (based on
the number of shares of Common Stock of the Issuer outstanding as of the Closing
Date as represented by the Issuer in the Purchase Agreement)  beneficially owned
by UtiliCorp. In aggregate, UtiliCorp beneficially ownership of 8,133,685 shares
of Issuer's  outstanding  common stock  represents  25.7% of Issuer's issued and
outstanding common stock. A schedule of UtiliCorp's transactions in the Issuer's
outstanding common stock is attached as an exhibit.

         Robert K. Green  beneficially  owns 10,000  shares of  Issuer's  common
stock, or 0.0% of the issued and outstanding  shares of Issuer's common stock. A
schedule of UtiliCorp's transactions in the Issuer's outstanding common stock is
attached as an exhibit.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY


     The Company represents and warrants to Purchaser which  representations and
warranties shall survive the Closing for a period of two years, as follows:

     Section 3.01 Corporate  Existence.  The Company:  (i) is a corporation duly
organized,  legally existing and in good standing under the laws of the State of
Delaware;  (ii)  has all  requisite  power,  and has all  material  governmental
licenses, authorizations, consents and approvals necessary to own its assets and
carry  on its  business  as its  business  is now  being or as its  business  is
proposed  to be  conducted;  and  (iii)  is  qualified  to do  business  in  all
jurisdictions  in which the nature of the  business  conducted  by it makes such
qualifications  necessary  and where failure so to qualify would have a Material
Adverse Effect. Neither the Company nor any of its Subsidiaries is in default in
the  performance,  observance or fulfillment of any provision of, in the case of
the Company,  its  Certificate  of  Incorporation,  as amended and restated,  or
Bylaws,  or, in

                                       9
<PAGE>

the case of any Subsidiary,  its Certificate of  Incorporation,  Bylaws or other
organizational  documents.  Schedule  3.01  identifies  each  Subsidiary  of the
Company  and the  ownership  of all  outstanding  Capital  Stock  of  each  such
Subsidiary.  Each  of the  Company's  Subsidiaries  that is a  corporation  is a
corporation duly organized, validly existing and in good standing under the laws
of the State or other  jurisdiction of its  incorporation  and has all requisite
power, and has all material governmental licenses, authorizations,  consents and
approvals  necessary to own its assets and carry on its business as now being or
as proposed to be  conducted.  Each of the Company and each of its  Subsidiaries
that is a  corporation  is duly  qualified or licensed and in good standing as a
foreign corporation,  and is authorized to do business,  in each jurisdiction in
which the ownership or leasing of its respective  properties or the character of
its respective operations makes such qualification  necessary,  except where the
failure to obtain such  qualification,  license,  authorization or good standing
would not have a Material Adverse Effect. Each Subsidiary of the Company that is
not a  corporation  has been duly formed and is duly  qualified  or licensed and
authorized to do business in each jurisdiction in which the ownership or leasing
of its respective properties or the character of its respective operations makes
such  qualification   necessary,   except  where  the  failure  to  obtain  such
qualification,  license  or  authorization  would  not have a  Material  Adverse
Effect.

     Section  3.02  Company SEC  Documents.  Company  has timely  filed with the
Commission all forms, registrations and proxy statements, reports, schedules and
statements required to be filed by it since December 31, 1997 under the Exchange
Act or the  Securities Act (all  documents  filed since such date,  collectively
"Company  SEC  Documents").  The  Company  SEC  Documents,   including,  without
limitation,  any financial statements or schedules included therein, at the time
filed (in the case of registration  statements and proxy  statements,  solely on
the dates of effectiveness  and the dates of mailing,  respectively)  (except to
the extent corrected by a subsequently filed Company SEC Document filed prior to
the Closing Date) (i) did not contain any untrue statement of a material fact or
omit to state a material  fact  required to be stated  therein or  necessary  in
order to make the statements  therein, in light of the circumstances under which
they were made, not misleading,  and (ii) complied in all material respects with
the applicable  requirements  of the Exchange Act and the Securities Act, as the
case may be, (iii) complied as to form in all material  respects with applicable
accounting  requirements  and with the published  rules and  regulations  of the
Commission with respect  thereto,  were prepared in accordance with GAAP applied
on a consistent basis during the periods involved (except as may be indicated in
the notes thereto or, in the case of unaudited statements,  as permitted by Form
10-Q of the  Commission),  and  (iv)  fairly  present  (subject  in the  case of
unaudited statements to normal, recurring and year-end audit adjustments) in all
material respects the consolidated financial position of Company as at the dates
thereof and the  consolidated  results of its  operations and cash flows for the
periods then ended.

     Section  3.03  No  Material  Adverse  Change.  Except  as set  forth  in or
contemplated  by the Company SEC Documents  filed with the  Commission as of the
date hereof or in Schedule  3.03,  since June 30, 1999,  each of Company and its
Subsidiaries has conducted its business in the ordinary course,  consistent with
past  practice,  and there  has been no (i)  change  that  could  reasonably  be
expected  to  have a  Material  Adverse  Effect  in the  business  or  financial
condition  of Company and its  Subsidiaries  taken as a whole,  other than those
occurring  as a result of general  economic  or  financial  conditions  or other
developments  which are not  unique to  Company  and its  Subsidiaries  but also
affect other Persons who  participate or are engaged in the

                                       10
<PAGE>

lines of  business  of which  Company and its  subsidiaries  participate  or are
engaged,  (ii) Material  Adverse  Effect on the ability of Company to consummate
the  transactions  contemplated  hereby,  (iii)  declaration,  setting  aside or
payment of any  dividend or other  distribution  with  respect to the  Company's
Capital  Stock,  (iv)  acquisition  or  disposition of any material asset by the
Company or any of its  Subsidiaries  or any contract or  arrangement  therefore,
otherwise than for fair value in the ordinary course of business or as disclosed
in the Company SEC Documents, or (v) material change in the Company's accounting
principles, practices or methods.

or as disclosed to Purchaser in Schedule 3.04, there is no Action pending or, to
the knowledge of the Company,  contemplated  or threatened  against or affecting

validity or enforceability of this Agreement,  any of the Basic Documents or any
other documents or agreements executed or to be executed by the Company pursuant
hereto or thereto or in connection herewith or therewith, or which (individually
or in the  aggregate)  reasonably  could be expected to have a Material  Adverse
Effect.

     Section 3.05 No Breach.  The  execution,  delivery and  performance  by the
Company of this  Agreement,  the Basic  Documents and all other  agreements  and
instruments  to be executed  and  delivered  by the Company  pursuant  hereto or
thereto or in connection  herewith or therewith,  compliance by the Company with
the terms and  provisions  hereof  and  thereof,  the  issuance  of the Series A
Preferred  Stock by the Company and the  application of the proceeds  thereof in
compliance  herewith do not and will not (a) violate any  provision  of any law,
statute,  rule  or  regulation,  order,  writ,  judgment,   injunction,  decree,
governmental permit,  determination or award having applicability to the Company
or any of its Subsidiaries or any of their respective  properties or assets, (b)

of the Company or its Subsidiaries, (c) require any consent (other than consents
set forth on Schedule  3.05),  approval or notice under or result in a violation
or breach of or constitute (with or without due notice or lapse of time or both)
a  default  (or  give  rise  to  any  right  of  termination,   cancellation  or
acceleration)  under (i) any note, bond,  mortgage,  license,  or loan or credit
agreement to which the Company or any of its Subsidiaries is a party or by which
the Company or any of its Subsidiaries or any of their respective properties may
be bound or (ii) any other such  agreement,  instrument  or  obligation,  or (d)
result in or require the creation or imposition of any Lien upon or with respect
to any of the properties  now owned or hereafter  acquired by the Company or any
of its Subsidiaries; with the exception of the conflicts stated in clause (b) of
this Section  3.05,  except where such  conflict,  violation,  default,  breach,
termination,   cancellation,   failure  to  receive  consent  or  approval,   or
acceleration with respect to the foregoing provisions of this Section 3.05 would
not,  individually or in the aggregate,  reasonably be likely to have a Material
Adverse Effect.

     Section 3.06  Authority.  The Company has all necessary power and authority
to execute,  deliver and perform its  obligations  under the Basic  Documents to
which it is a party; and the execution,  delivery and performance by the Company

necessary  action on its part;  and the Basic  Documents  constitute  the legal,
valid and binding  obligations of the Company,  enforceable  in accordance  with
their  terms,  except  as such  enforceability  may be  limited  by  bankruptcy,

the  execution,  delivery or performance by the Company of this Agreement or any
of the Basic  Documents or the issuance by the Company of the Series A Preferred
Stock or the  Conversion  Shares,  except  where the  failure  to  receive  such
authorization,  consent,  approval,  waiver,  license,  qualification or written
exemption  from,  or  to  make  such  filing,   declaration,   qualification  or
registration would not,  individually or in the aggregate,  reasonably be likely
to have a Material Adverse Effect.

file such  returns or to pay, or make  provision  for the payment of, such taxes

Subsidiaries,  taken as a whole.  Except  as set  forth in  Schedule  3.09,  the
Company has no knowledge of any tax deficiency  which has been asserted  against
the Company or any  Subsidiary  which the Company  reasonably  expects to have a

     condition  or  occurrence  described in clauses (i) or (ii) which could not
     reasonably be expected to have a Material Adverse Effect.

          (b) Hazardous Materials.  Except as set forth on Schedule 3.15, to the
     knowledge of the Company (i) Hazardous  Materials have not at any time been
     generated,  used,  treated or stored  on, or  transported  to or from,  any

     manner  that has  violated or could  reasonably  be expected to violate

                                       13

     any Environmental Law, except for such violation which could not reasonably
     be expected to have a Material Adverse Effect, and (ii) Hazardous Materials
     have  not at any  time  been  released  on or from  any  property  owned or

assets  similar  to  those  of the  Company  and its  Subsidiaries.  There is no
material  claim pending under any of such policies or bonds as to which coverage
has been, nor any basis for Company to reasonably  believe that a material claim
will be, questioned,  denied or disputed by the underwriters of such policies or
bonds.  All premiums due and payable under all such policies and bonds have been
paid and Company and its Subsidiaries are otherwise in compliance with the terms
of  such  policies  and  bonds.  Company  has no  knowledge  of  any  threatened
termination  of, or  material  premium  increase  with  respect  to, any of such
policies.  Schedule 3.16  identifies all risks, if any, of the Company or any of

Company is not a party to any voting  trust or other  agreement  with respect to
the voting of its Capital  Stock.  Except as set forth in Schedule 3.17 or under

issuable under currently  outstanding  options as of the Share Calculation Date,
there  are as of the  Share  Calculation  Date  no  (i)  outstanding  securities
convertible  into or  exchangeable  for  Capital  Stock of the  Company  or (ii)
contracts, commitments,  agreements,  understandings or arrangements of any kind
to which the Company is a party obligating the Company under any circumstance to
issue any Capital Stock, or any securities  convertible into or exchangeable for

or bound by any  agreement  with respect to any of its  securities  which grants
registration rights to any Person.

Affiliates) and will not be subject to any restriction on the voting or transfer
thereof created by the Company, other than the restrictions set forth in Section
4.01 and Section 4.05 of this  Agreement and pursuant to the  Investor's  Rights
Agreement.  The Company has duly and validly reserved the Conversion  Shares for
issuance upon conversion of the Shares.

     Section  3.19  Certain  Fees.  Except  for the fees  payable  to  Purchaser
pursuant  to this  Agreement,  no fees or  commissions  will be  payable  by the
Company to brokers,  finders,  investment  bankers, or Purchaser with respect to
the  issuance  and  sale  of any  of  the  Shares  or  the  consummation  of the
transaction  contemplated  by this  Agreement.  The Company  agrees that it will
indemnify  and hold  harmless  Purchaser  from and  against  any and all claims,
demands, or liabilities for broker's,  finders, placement, or other similar fees
or  commissions  incurred by the Company or alleged to have been incurred by the
Company  in  connection  with  the  issuance  or  sale  of  the  Shares  or  the
consummation of the transaction contemplated by this Agreement.

     Section 3.20 Licenses.  Except as set forth in Schedule  3.20,  each of the
Company and its Subsidiaries holds all licenses, franchises,  permits, consents,
registrations,  certificates and other approvals (including, without limitation,
those  relating  to   environmental   matters  and  worker  health  and  safety)
(individually,  a "License"  and,  collectively,  "Licenses")  required  for the
conduct of its business as now being conducted, except where the failure to hold
any such License would not have a Material Adverse Effect.

     Section  3.21  Undisclosed  Liabilities.  Except  (a) as and to the  extent
disclosed or reserved against on the consolidated balance sheet of Company as of
June 30, 1999 or the notes  thereto  included in the  Company SEC  Documents  or
otherwise disclosed in the Company SEC Documents filed with the Commission as of
the date hereof (b) those incurred in connection with the execution of the Basic
Documents (c) obligations incurred in the ordinary course of business subsequent
to June 30, 1999 or (d) as set forth in Schedule 3.21,  neither  Company nor any
of its subsidiaries  have any liabilities or obligations of any nature,  whether
known or unknown, absolute,  accrued, contingent or otherwise and whether due or
to become  due,  and that would be required  by GAAP to be  disclosed  and that,
individually or in the aggregate, have or would reasonably be expected to have a
Material Adverse Effect.

     Section 3.22 Labor  Relations.  Except as disclosed on Schedule 3.22, there
is no unfair  labor  practice  litigation  involving  the  Company or any of its
subsidiaries either pending before the National Labor Relations Board or a court
or, to the  knowledge  of  Company,  threatened  against  Company  or any of its
subsidiaries.  Except as disclosed on Schedule  3.22,  there is no labor strike,
dispute,  slowdown or stoppage,  either pending or, to the knowledge of Company,
threatened  against  Company  or any of its  subsidiaries,  nor has the  Company
experienced any such labor  interruptions  over the past two years.  The Company
considers its relationship with its employees to be good.

     Section  3.23  Year  2000  Compliance.  All  devices,  systems,  machinery,
information technology, computer software and hardware, and other date sensitive
technology  (jointly and severally its "systems")  necessary for the Company and
its  Subsidiaries  to carry on their  business as presently  contemplated  to be
conducted  will be Year 2000  Compliant  within a period of time  calculated  to
result  in no  material  disruption  of any of their  business  operations.  For
purposes

                                       15
<PAGE>

hereof,  "Year 2000  Compliant"  means that such systems are designed to be used
prior to,  during  and  after the  Gregorian  calendar  year 2000 A.D.  and will
operate  during  each such time  period  without  error  relating  to date data,
specifically including any error relating to, or the product of, date data which
represents  or  references  different  centuries or more than one  century.  The
Company  and its  Subsidiaries  will (a)  undertake  an  inventory,  review  and
assessment of all areas within their  businesses  and  operations  that could be
adversely affected by the failure of the Company and its Subsidiaries to be Year
2000  Compliant  on a timely  basis  and (b)  develop  a plan and time  line for
becoming Year 2000 Compliant on a timely basis. The Company,  when it reasonably
determines such action  necessary,  will make written inquiry of each of its and
its  Subsidiaries'  key suppliers,  vendors,  and customers,  and will obtain in
writing  confirmations  from all such  Persons,  as to whether such Persons have
initiated  programs  to become Year 2000  Compliant.  For  purposeshereof,  "key
suppliers,  vendors,  and customers"  refers to those  suppliers,  vendors,  and
customers  of the Company and its  Subsidiaries  whose  business  failure  could
reasonably be expected to have a Material  Adverse Effect.  The Company does not
control third party hardware or software  systems that may interfere or exchange
data with the Company's material hardware and software systems and the foregoing
representation  specifically  excludes any representation  that such third party
hardware and software systems are Year 2000 Compliant.

                 REPRESENTATIONS AND WARRANTIES OF THE PURCHASER


     Purchaser represents and warrants to the Company, which representations and
warranties  shall  survive the execution of any Basic  Document,  that as of the
date of this Agreement:

     Section  4.01  Investment.   Purchaser  represents  and  warrants  to,  and
covenants  and agrees with,  the Company that the Shares are being  acquired for
its  own  account,  not  as a  nominee  or  agent,  and  with  no  intention  of
distributing  or  reselling  the  Shares  or the  Conversion  Shares or any part
thereof and that  Purchaser has no present  intention of selling or granting any
participation  in or otherwise  distributing  the same in any transaction  which
would be in violation of the securities  laws of the United States of America or
any State, without prejudice, however, to Purchaser's right at all times to sell
or otherwise  dispose of all or any part of the Shares or the Conversion  Shares
under a registration  statement  under the  Securities Act and applicable  state
securities  laws  or  under  an  exemption  from  such  registration   available
thereunder (including,  without limitation,  if available,  Rule 144 promulgated
thereunder).  If Purchaser  should in the future decide to dispose of any of the
Shares or the Conversion  Shares,  Purchaser  understands and agrees (a) that it
may do so only (i) in compliance  with the Securities  Act and applicable  state
securities  law, as then in effect,  and (ii) in the manner  contemplated by any
registration  statement pursuant to which such securities are being offered, and
(b) that  stop-transfer  instructions  to that  effect  will be in  effect  with
respect  to such  securities.  Purchaser  agrees to the  imprinting,  so long as
appropriate,  of a legend on each certificate representing the Securities to the
effect as set forth above.

     Section 4.02 Nature of Purchaser. Purchaser represents and warrants to, and
covenants and agrees with, the Company that, (a) it is an "accredited  investor"
within the meaning of Rule 501 of Regulation D promulgated by the Securities and
Exchange  Commission  pursuant  to

                                       16
<PAGE>

the Securities Act and (b) by reason of its business and financial experience it
has such  knowledge,  sophistication  and  experience  in business and financial
matters  so  as to be  capable  of  evaluating  the  merits  and  risks  of  the
prospective  investment in the Securities,  is able to bear the economic risk of
such  investment  and, at the present  time,  would be able to afford a complete
loss of such investment.

     Section 4.03 Receipt of Information;  Authorization. Purchaser acknowledges
that  it  has  had  access  to  information  regarding  the  business,   assets,
operations, financial condition and results of operations of the Company and has
been provided a reasonable  opportunity to ask questions of and receive  answers
from  representatives  of the Company regarding such matters.  Purchaser further
acknowledges that it is experienced in investing in corporations and businesses.
Purchaser represents and warrants that the purchase of the Shares by it has been
duly and properly authorized and this Agreement and each other Basic Document to
which  Purchaser is (or will at the Closing be) a signatory  have been (or, with
respect to the other Basic Documents,  at the Closing will be) duly executed and
delivered by it or on its behalf.

     Section  4.04  Anti-Hedging.  Purchaser  represents  and  warrants  to, and
covenants and agrees with, the Company that it will not at any time prior to the
tenth  anniversary  of the  Closing  Date engage in any put,  call,  short-sale,
hedge,  straddle or similar  transactions in Company's Capital Stock intended to
reduce  Purchaser's risk of owning the Company's Capital Stock,  excluding index
options or similar basket hedges.

     Section  4.05  Restricted   Securities.   Purchaser  understands  that  the
Securities it is purchasing are  characterized as "restricted  securities" under
the federal securities laws inasmuch as they are being acquired from the Company
in a transaction  not  involving a public  offering and that under such laws and
applicable  regulations such securities may be resold without registration under
the Securities Act, only in certain limited  circumstances.  In this connection,
such  Purchaser  represents  that it is familiar with Rule 144 of the Commission
promulgated under the Securities Act.

     Section  4.06  Certain  Fees.  No fees or  commissions  will be  payable by
Purchaser  to  brokers,  finders,  or  investment  bankers  with  respect to the
purchase  of any of  the  Securities  or  the  consummation  of the  transaction
contemplated  by this  Agreement.  Purchaser  agrees  that it will,  jointly and
severally,  indemnify and hold harmless the Company from and against any and all
claims,  demands,  or liabilities  for broker's,  finders,  placement,  or other
similar  fees or  commissions  incurred  by  Purchaser  or  alleged to have been
incurred by Purchaser in connection  with the purchase of the  Securities or the
consummation of the transaction contemplated by this Agreement.

     Section 4.07 No Implied  Representations.  Notwithstanding  anything to the
contrary  contained  in  this  Agreement,  it is the  express  understanding  of
Purchaser  that  the  Company  is not  making  any  representation  or  warranty
whatsoever,  express or implied, other than those representations and warranties
of Company expressly set forth in this Agreement.

Agreement.

duties to its  stockholders)  to take such actions that will enable Purchaser to

efficient  manner (as determined by Purchaser in the reasonable  exercise of its
discretion)  including,  but  not  limited  to,  a  redemption  or a  series  of
redemption's at fair market value or a recapitalization of Purchaser's  interest
in the Company and its operations on a pretax basis (and calling a stockholders'
meeting,  if required,  and recommending the approval of said exit,  subject, in
all cases, to the Company's  fiduciary duties to its stockholders).  The Company

reasonable exercise of its discretion), including, but not limited to, the grant
of a right to convert or exchange  such shares of Common Stock into or for a new
series of preferred  stock or a different  class of common stock,  in each case,
having  similar  attributes  as the  Series A  Preferred  Stock  (and  calling a
stockholders'  meeting at the earliest  opportunity after a request by Purchaser
and  recommending  the approval of such actions,  subject,  in all cases, to the
Company's   fiduciary  duties  to  its  stockholders).   The  Company  will  use
commercially  reasonable efforts to secure the agreement of certain Stockholders
of the  Company  to vote  for such  action,  consistent  with the  stockholders'
fiduciary duties (if any) to the Company or its stockholders.

     Section 6.11 Assistance in Purchasing  Common Stock. To assist Purchaser in
its efforts to acquire, in one or more privately negotiated transactions, Common
Stock currently  outstanding,  the Company shall identify  current  stockholders
that may potentially  desire to sell their Common Stock and will provide contact

Stockholders  Rights  Plan that could have the  effect of  reducing  UtiliCorp's
Fully Diluted Ownership Ratio below 49.9%.

     Section 6.13 Termination of Certain  Covenants.  The covenants set forth in
Sections 6.01,  6.02,  6.06, 6.09, and 6.10 shall terminate and be of no further

other  party  of such  threat,  and the  parties  shall,  through  lawfully  and
commercially reasonable efforts, defend the Basic Documents against such threat.

     Section 6.15 Nomination of UtiliCorp Director  Designee(s).  If at any time
UtiliCorp  would be entitled  to elect one or more  directors  to the  Company's
Board of Directors  pursuant to the terms of Section 3(b) of the  Certificate of
Designation,  but for the  unenforceability  of such provision under  applicable
law, the Company agrees to cause the person(s)  that would have been  designated
by UtiliCorp  under such  section to be nominated as directors to the  Company's
Board of Directors.

Schedule,  and  Exhibit  references  are to  this  Agreement,  unless  otherwise
specified. All references to instruments,  documents,  contracts, and agreements
are references to such instruments,  documents, contracts, and agreements as the
same may be amended,  supplemented,  and  otherwise  modified from time to time,
unless otherwise  specified.  The word "including" shall mean "including but not
limited to." Whenever the Company has an obligation  under the Basic  Documents,
the expense of complying with that obligation shall be an expense of the Company
unless otherwise specified. Whenever any determination,  consent, or approval is
to be made or given by  Purchaser,  such  action  shall be in  Purchaser's  sole
discretion unless otherwise specified in this Agreement. If any provision in the
Basic Documents is held to be illegal,  invalid,  not binding, or unenforceable,
such  provision  shall be  fully  severable  and the  Basic  Documents  shall be
construed  and  enforced  as  if  such  illegal,   invalid,   not  binding,   or
unenforceable  provision had never comprised a part of the Basic Documents,  and
the  remaining  provisions  shall  remain in full  force and  effect.  The Basic
Documents have been reviewed and negotiated by sophisticated parties with access
to  legal  counsel  and  shall  not  be  construed  against  the  drafter.   The
representation and warranties shall survive for the applicable  two-year periods
identified in the first  paragraph of Article III above,  and the covenants made
in this Agreement,  or any other Basic Document shall survive the closing of the
transactions  described herein and remain operative and in full force and effect
regardless  of (a) any  investigation  made by or on  behalf of the  Company  or
Purchaser or (b) acceptance of any of the  Securities  and payment  therefor and
repayment or repurchase thereof. All indemnification  obligations of the Company
and the provisions of Section 7.02 shall remain  operative and in full force and
effect unless such obligations are expressly terminated in a writing referencing
those individual  Sections,  regardless of any purported general  termination of
this Agreement.

     to  indemnify   Purchaser,   and  its   officers,   directors,   employees,
     representatives,  agents, attorneys, and Affiliates (collectively, "Related

     arrangements, (collectively, the "Indemnity Matters") which may be incurred
     by them or  asserted  against or involve any of them as a result of a claim
     by a Person that is not an Affiliate  of  Purchaser or any Related  Parties
     under clauses (i), (ii), (iii) and (v) below (whether or not any of them is
     designated a party  thereto) as a result of,  arising out of, or in any way
     related to (i) any actual or proposed use by the Company of the proceeds of
     any sale of the  Securities,  (ii) the  operations  of the  business of the
     Company or any of its  Affiliates,  (iii) the failure of the Company or any
     of its  Affiliates to comply with any  Governmental  Requirement,  (iv) the
     breach of the  representations,  warranties  and  covenants  of the Company
     contained  herein,  provided such claim for  indemnification  relating to a
     breach  of  the  representations  and  warranties  is  made  prior  to  the
     expiration of such representations and warranties,  or (v) any other aspect
     of this  Agreement  and  the  other  Basic  Documents,  including,  without
     limitation,  the reasonable fees and disbursements of counsel and all other
     reasonable expenses incurred in connection with investigating, defending or
     preparing  to defend  any such  action,  suit,  proceeding  (including  any
     investigations,  litigation,  or  inquiries),  or claim and  INCLUDING  ALL
     INDEMNITY  MATTERS  ARISING BY REASON OF THE  NEGLIGENCE OF ANY  INDEMNITEE
     (but not  Indemnity  Matters  related  solely  to the gross  negligence  or
     willful misconduct of any Indemnitee).

          (b)  Indemnification  Regarding  Taxes.  The Company agrees to pay and
     hold  Purchaser  harmless  from and  against any and all present and future
     stamp and other  similar  taxes with  respect to this  Agreement  and Basic
     Documents  and  save  Purchaser  harmless  from  and  against  any  and all
     liabilities  with respect to or resulting from any delay or omission to pay
     such taxes, and will indemnify  Purchaser for the full amount of taxes paid
     by Purchaser  (not to include  income or gross  receipt tax  liability)  in
     respect of payments  made or to be made under this  Agreement  or any other
     Basic  Document  and any  liability  (including  penalties,  interest,  and
     expenses)  arising  therefrom or with respect thereto,  whether or not such
     taxes were correctly or legally asserted.

          (c)  Indemnification  Regarding  Environmental  Matters.  The  Company
     agrees to indemnify  and hold  harmless  from time to time  Purchaser,  and
     their  respective  Related  Parties  from and  against  any and all losses,
     claims,  cost  recovery  actions,  administrative  orders  or  proceedings,
     damages,  and liabilities to which Purchaser and their  respective  Related
     Parties  may incur,  have  asserted  against  them or  involve  any of them
     pursuant to a claim by a Person that is not an  Affiliate  of  Purchaser or
     any  Related  Parties (i) under any  Environmental  Law  applicable  to the
     Company, any Subsidiary,  or any of their respective Properties,  (ii) as a
     result of the breach or  non-compliance  by the  Company or any  Subsidiary
     with any Environmental Law applicable to the Company or any Subsidiary,  or
     any of their  respective  Properties,  (iii)  due to the  ownership  by the
     Company or any Subsidiary of their respective Properties or any activity on
     any of their  respective  Properties,  or any past activity on any of their
     respective  Properties  which,  though lawful and fully  permissible at the
     time, could result in present liability under

                                       25
<PAGE>

     any Environmental Law, (iv) the presence, use, release, storage, treatment,
     or disposal of hazardous substances on or at any of the properties owned or
     operated by the Company or any Subsidiary,  or (v) any other environmental,
     health,  or safety condition in connection with this Agreement or any other
     Basic Document.

          (d)  Indemnification  Procedure.  Promptly  after  Purchaser  or other
     Person indemnified  hereunder  (hereinafter,  the "Indemnified  Party") has
     received  notice  or  has  knowledge  of  any  claim  for   indemnification
     hereunder,  or the  commencement  of any  action or  proceeding  by a third
     person,   which  the  Indemnified  Party  believes  in  good  faith  is  an
     indemnifiable claim under this Agreement,  the Indemnified Party shall give
     the Company written notice of such claim or the commencement of such action
     or  proceeding,  but failure so to notify the Company  will not relieve the
     Company  from any  liability  which it may have to such  Indemnified  Party
     hereunder except to the extent that the Company is materially prejudiced by
     such  failure.  Such  notice  shall  state the nature and the basis of such
     claim.  The Company  shall have the right to defend and settle,  at its own
     expense  and by its own  counsel,  any such  matter as long as the  Company
     pursues the same diligently and in good faith. If the Company undertakes to
     defend or settle,  it shall promptly  notify the  Indemnified  Party of its
     intention  to do so, and the  Indemnified  Party shall  cooperate  with the
     Company  and its  counsel in all  commercially  reasonable  respects in the
     defense thereof and the settlement thereof. Such cooperation shall include,
     but shall not be limited to, furnishing the Company with any books, records
     and  other  information  reasonably  requested  by the  Company  and in the
     Indemnified  Party's  possession  or  control.   Such  cooperation  of  the
     Indemnified  Party shall be at the cost of the  Company.  After the Company
     has notified the Indemnified  Party of its intention to undertake to defend
     or  settle  any such  asserted  liability,  and for so long as the  Company
     diligently  pursues such  defense,  the Company shall not be liable for any
     additional legal expenses  incurred by the Indemnified  Party in connection
     with any  defense  or  settlement  of such  asserted  liability;  provided,
     however,  that the Indemnified  Party shall be entitled (i) at its expense,
     to  participate  in  the  defense  of  such  asserted   liability  and  the
     negotiations  of the  settlement  thereof  or (ii) if (A) the  Company  has
     failed to assume the defense and employ counsel or (B) if the defendants in
     any such  action  include  both the  Indemnified  Party and the Company and
     counsel to the  Indemnified  Party shall have  concluded  that there may be
     reasonable  defenses  available to the Indemnified Party that are different
     from or additional to those available to the Company or if the interests of
     the  Indemnified  Party  reasonably  may be  deemed  to  conflict  with the
     interests of the Company,  then the Indemnified  Party shall have the right
     to select a separate counsel and to assume such legal defense and otherwise
     to participate in the defense of such action, with the expenses and fees of
     such separate counsel and other expenses  related to such  participation to
     be reimbursed by the Company as incurred,  and the Company shall not settle
     any such claim  without the  consent of the  Indemnified  Party  unless the
     settlement  thereof  imposes no liability or obligation  on, and includes a
     complete  release  from  liability  of,  the  Indemnified   Party.  If  the
     Indemnified  Party undertakes such a defense through counsel of its choice,
     the  Indemnified  Party may  settle  such  matter,  and the  Company  shall
     reimburse the Indemnified  Party for the amount paid in such settlement and
     any other  liabilities  or expenses  incurred by the  Indemnified  Party in
     connection therewith.

          (e) Survival.  The Company's obligations under this Section 7.02 shall
     survive  any   termination  of  this  Agreement  and  the  payment  of  the
     Obligations.

     accordance  with  the  terms  and  conditions  of  the  Investor's   Rights

     Section 7.07  Governing Law. This Agreement will be construed in accordance

principles of conflicts of laws.

     Section 7.08 Arbitration.  Any action, dispute, claim or controversy of any
kind between the Company and a Purchaser  arising out of, or  pertaining to this
Agreement  or the  transactions  contemplated  hereby  (a  "Dispute")  shall  be
resolved by binding  arbitration in accordance with the terms hereof.  Any party
may, by summary  proceedings,  bring an action in court to compel arbitration of
any Dispute.  Any arbitration shall be administered by the American  Arbitration
Association  (the "AAA") in accordance  with the terms of this Section 7.08, the
Commercial  Arbitration Rules of the AAA, and, to the maximum extent applicable,
the Federal Arbitration Act. Judgment on any award rendered by an arbitrator may
be entered in any court having jurisdiction.  Any arbitration shall be conducted
before a three  person  panel of  arbitrators.  Such panel shall  consist of one
person designated by the Company, one designated by Purchaser and one designated
by the designees of the Company and Purchaser (collectively, the "Arbitrators").
Such arbitrators  designated by each of the Company and Purchaser do not have to
be  neutral.  If  either of the  Company  or  Purchaser  fails to  designate  an
arbitrator  within 10 days  after the  filing of the  Dispute  with the AAA,  or
either of the  Company or  Purchaser's  arbitrators  fails to  designate a third
arbitrator  within  30 days  after the  later of their  appointments,  the third
arbitrator  shall be appointed by the AAA. An arbitration  proceeding  hereunder
shall be conducted in Kansas City,  Missouri,  and shall be concluded within 180
days of the  filing  of the  Dispute  with the  AAA.  The  Arbitrators  shall be
empowered  to award  sanctions  and to take  such  other  actions  as they  deem
necessary,  to the same extent a judge could impose sanctions or take such other
actions  pursuant to the Federal Rules of Civil Procedure and applicable law. No
award by the  Arbitrators  shall  assess  consequential,  punitive or  exemplary
damages or damages  for lost  profits  but may assess  costs and  expenses  in a
manner deemed equitable.  The arbitrator shall make specific written findings of
fact and  conclusions of law. The decision of the arbitrator  shall be final and
binding on each party. All fees of the Arbitrators and any engineer,  accountant
or other consultant  engaged by the Arbitrators shall be paid by the Company and
Purchaser as awarded by the Arbitrators.

     Section 7.09 Execution in  Counterparts.  This Agreement may be executed in
any  number  of  counterparts  and  by  different  parties  hereto  in  separate
counterparts,  each of which counterparts, when so executed and delivered, shall
be deemed to be an original and all of which counterparts, taken together, shall
constitute but one and the same Agreement.

                          STRATEGIC ALLIANCE AGREEMENT

     This Strategic Alliance Agreement ("Agreement") is made and entered into as
of  September  21,  1999,  by and  between  Quanta  Services,  Inc.,  a Delaware
corporation  ("Company")  and  UtiliCorp  United  Inc.,  a Delaware  corporation
("UtiliCorp").

                                     RECITAL

     This Agreement is made pursuant to the Securities Purchase Agreement, dated
as of September 21, 1999, by and between the Company and UtiliCorp  ("Securities
Purchase  Agreement").  In order to provide mutual inducements to enter into the
Securities  Purchase  Agreement  in  addition to those  expressly  stated in the
Securities  Purchase  Agreement,  the  Company  has  agreed  to  use  reasonable
commercial  efforts to provide  certain  services to UtiliCorp and UtiliCorp has
agreed to use  reasonable  commercial  efforts to contract  with the Company for
such services on the terms and conditions set forth in this Agreement.  Pursuant
to the  Securities  Purchase  Agreement,  UtiliCorp  will acquire  shares of the
Company's  Convertible  Preferred Stock  ("Preferred  Stock") which will entitle
UtiliCorp to convert the Preferred Stock into shares of Common Stock,  par value
$0.00001 per share, of the Company. The execution and delivery of this Agreement
shall occur  contemporaneously  with the  Closing (as defined in the  Securities
Purchase Agreement).  Capitalized terms used in this Agreement and not otherwise
defined  herein  shall have the  meanings  ascribed  thereto  in the  Securities
Purchase Agreement.

                                    AGREEMENT

     The parties agree as follows:

Section 1.  Services to be Performed by the Company.

     UtiliCorp will use the Company, subject to the Company's ability to perform
services in  designated  locations,  as a  preferred  contractor  in  outsourced
transmission  and distribution  infrastructure  construction and maintenance and
natural gas  distribution  construction and maintenance in all areas serviced by
UtiliCorp,  provided  that the Company  provides  such services at a competitive
cost that is demonstrably  equal to or better than current market rates for such
services when the quality of the Company's services is considered. UtiliCorp and
the Company will also discuss and explore the  Company's  potential  purchase of
other electric  transmission and distribution and natural gas contractors  owned
by or affiliated with UtiliCorp and will negotiate in good faith with respect to
proposed terms of acquisition in the event that UtiliCorp  determines to dispose
of any such contractors owned by or affiliated with UtiliCorp. In furtherance of
these  objectives,  the parties agree that UtiliCorp shall regularly provide the
Company the  following  to the extent  pertinent  to the  provision  of services
pursuant to this Agreement:

     (a)  Evaluation of "value engineering" proposals;

     (b)  Recommendations  for improvement and cost reduction between UtiliCorp,

informational  requirements as outlined in Section 1 of this Agreement;  (ii) to
present for consideration by the other party proposals and opportunities for the

to explore  and  evaluate  ways in which the Company  and  UtiliCorp  might work
together to enhance their respective businesses.

     In connection with the foregoing, the parties hereto shall, as appropriate,
use reasonable  efforts (i) to arrange meetings from time-to-time  between their
respective representatives to discuss such matters, (ii) to provide to the other
party  from  time-to-time  reasonable  access to  information  pertinent  to the

communication  between  UtiliCorp  and its  Affiliates  on the one  hand and the
Company on the other hand to facilitate  access to  information  and  personnel,
subject,  however,  to  limitations  imposed  by  applicable  law  and  existing
confidentiality   obligations  as  well  as  internal  policies   regarding  the

Section 4.  Protection of Employees.

     From and after the date  hereof  until the date one (1) year after the term

knowledge of this  Agreement or the  transactions  contemplated  hereby and (ii)
none of the soliciting  party's (or any of its  Affiliates')  personnel who have
knowledge of this Agreement or the transactions  contemplated hereby have actual

deemed to include general  solicitations of employment not specifically directed
towards employees of a party hereto or its Affiliates.

Section 5.  Confidentiality.

     In connection with the matters described in this Agreement,  each party may
provide to the other certain  information that is  confidential,  proprietary or
otherwise  not generally  available to the public.  As a condition to furnishing
such information the parties agree as follows:

     (a)  Nondisclosure  of  Confidential  Information.  From and after the date
          hereof,  until  the  date  two  years  after  the  disclosure  of  the
          particular   Confidential   Information  (as  defined   below),   such
          Confidential  Information  shall be used solely in connection with the
          matters  contemplated  by this  Agreement,  and the  recipient  of the
          Confidential   Information   shall  not  disclose   the   Confidential
          Information to any person other than those of its directors, officers,
          employees,  lenders,  counsel,  representatives and Affiliates, if any
          (those such persons who actually receive any confidential  information
          hereunder being collectively,  the "Representatives") who need to know
          the   Confidential   Information.   It  is  understood  that  (i)  the
          Representatives  shall be informed of the  confidential  nature of the
          Confidential Information and the requirement that it not be used other
          than for the  purposes  described  herein and (ii) in any  event,  the
          party receiving Confidential  Information shall be responsible for any
          breach of this Section by any of its  Representatives.  Each party may
          also disclose the Confidential Information in order to comply with any
          applicable  law,  order,  regulation or ruling or stock exchange rule.
          The  term  "person"  as used  in  this  Section  5  shall  be  broadly


                                       3
<PAGE>

          interpreted to include, without limitation, any corporation,  company,
          partnership, individual or other entity.

     (b)  Definition   of   "Confidential   Information".    As   used   herein,
          "Confidential  Information"  means all  information  that is furnished
          under this  Agreement by a party  hereto,  and which is  confidential,
          proprietary  or  otherwise  not  generally  available  to the  public.
          Notwithstanding  the  foregoing,  the  following  will not  constitute
          Confidential Information for purposes of this Section: (i) information
          that is or becomes  generally  available to the public other than as a
          result  of a  breach  of this  Section  by the  party  receiving  such
          information or its  Representatives;  (ii) information  that, prior to
          being furnished pursuant hereto, was already in the files of the party
          receiving such information or its Representatives  from another source
          not known to be subject to any prohibition  against  transmitting  the
          information;  or (iii) information that becomes available to the party
          receiving such information or its Representatives  from another source
          not known to be subject to any prohibition  against  transmitting  the
          information.

     (c)  Return of Information.  The written Confidential  Information,  except
          for that portion of the Confidential  Information that may be found in
          analyses, compilations,  studies or other documents prepared by or for
          the party  receiving the  Confidential  Information,  will be returned
          promptly upon any request made during the two year period  referred to
          in Section  5(a) above,  and no copies  shall be retained by the party
          receiving the Confidential  Information or its  Representatives.  That
          portion of the Confidential Information that may be found in analyses,
          compilations,  studies or other documents prepared by or for the party
          receiving the Confidential Information,  oral Confidential Information
          and written Confidential Information not so requested or returned will
          be held by the party receiving the  Confidential  Information and kept
          subject to the terms of this Section, or destroyed.

     (d)  Remedies.  Both  parties  acknowledge  that  remedies  at  law  may be
          inadequate  to protect  the  disclosing  party  against  any actual or
          threatened  breach of this  Agreement  by the  recipient,  and without
          prejudice to any other rights and remedies otherwise  available to the
          disclosing party,  agree to the granting of injunctive relief in favor
          of the  disclosing  party  without  proof of  actual  damages.  If the
          disclosing  party  is  required  to post a bond to  obtain  injunctive
          relief, the parties agree that such bond shall not exceed One Thousand
          Dollars ($1,000).

Section 6.  No Authority to Bind; No Fiduciary Relationship.

     Neither party hereto shall have the authority to bind or to purport to bind
the other party hereto.  The parties  agree that no  employment,  agency,  joint
venture,  partnership,  advisory or  fiduciary  relationship  shall be deemed to
exist or arise  between them with respect to the  transactions  contemplated  by
this Agreement;  any such  relationship  shall exist only as expressly stated in
any future definitive agreements.

Section 7.  Publicity.

     Any press release or other public announcement regarding or relating to the
existence of this  Agreement and its contents  shall be mutually  agreed upon by
the parties.

Section 8.  Miscellaneous.

     (a)  Dispute Resolution.  Any action,  dispute, claim or controversy of any
          kind now  existing  or  hereafter  arising  between  the  Company  and
          UtiliCorp  arising  out  of,  pertaining  to  this  Agreement  or  the
          transactions  contemplated  hereby  ("Dispute")  shall be  resolved by
          binding  arbitration  in accordance  with the terms hereof.  Any party
          may,  by  summary  proceedings,  bring an  action  in court to  compel
          arbitration of any Dispute.  Any arbitration  shall be administered by
          the American  Arbitration  Association  ("AAA") in accordance with the
          terms of this Section 8, the Commercial  Arbitration Rules of the AAA,
          and, to the maximum extent  applicable,  the Federal  Arbitration Act.
          Judgment on any award  rendered by an arbitrator may be entered in any
          court having jurisdiction. Any arbitration shall be conducted before a
          panel of three  arbitrators.  Such panel  shall  consist of one person
          designated  by the  Company,  one  designated  by  UtiliCorp  and  one
          designated  by their  designees.  The  arbitrators  designated  by the
          parties are not required to be neutral.  If a party fails to designate
          an arbitrator  within 10 calendar days after the filing of the Dispute
          with the AAA, or the  parties'  arbitrators  fail to designate a third
          arbitrator   within  30  calendar   days  after  the  later  of  their
          appointments,  such  arbitrator  shall be  appointed  by the  AAA.  An
          arbitration   proceeding  hereunder  shall  be  concluded  within  180
          calendar  days of the filing of the Dispute with the AAA.  Arbitration
          proceedings shall be conducted in Kansas City,  Missouri.  Arbitrators
          shall be empowered to award  sanctions  and to take such other actions
          as they  deem  necessary,  to the  same  extent a judge  could  impose
          sanctions or take such other actions  pursuant to the Federal Rules of
          Civil Procedure and applicable law. No award by the arbitrators  shall
          assess  consequential,  punitive or  exemplary  damages but may assess
          costs and expenses in a manner deemed equitable. The arbitrators shall
          make specific  written  findings of fact and  conclusions  of law. The
          decision of the arbitrators shall be final and binding on each party.

     (b)  Communications.  All notices and other communications  provided for or
          permitted  hereunder  shall be made in  writing by  telecopy,  courier
          service or personal delivery:

          i.   if to  UtiliCorp,  initially  at the  address  set  forth  in the
               Securities Purchase Agreement, and

          ii.  if to the  Company,  initially  at its  address  set forth in the
               Securities Purchase Agreement,

               and  thereafter  in each case at such  other  address,  notice of
               which is given in accordance  with the provisions of this Section
               8.

         All such  notices  and  communications  shall be  deemed  to have  been
         received at the time delivered by hand, if personally  delivered;  when
         receipt  acknowledged,  if telecopied  or sent via Internet  electronic
         mail; and when actually received, if sent by any other means.

     (c)  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
          counterparts and by the parties hereto in separate counterparts,  each
          of which counterparts, when so executed and delivered, shall be deemed
          to be an original and all of which counterparts, taken together, shall
          constitute but one and the same Agreement.

     (d)  Headings.  The  headings  in this  Agreement  are for  convenience  of
          reference  only and shall not limit or  otherwise  affect the  meaning
          hereof.

     (e)  Governing  Law.  The laws of the State of Missouri  shall  govern this
          Agreement without regard to principles of conflict of laws.

     (f)  Severability  of Provisions.  Any provision of this Agreement which is
          prohibited or  unenforceable  in any  jurisdiction  shall,  as to such
          jurisdiction,  be  ineffective  to the extent of such  prohibition  or
          unenforceability  without invalidating the remaining provisions hereof
          or  affecting  or impairing  the  validity or  enforceability  of such
          provision in any other jurisdiction.

     (g)  Entire Agreement. This Agreement is intended by the parties as a final
          expression  of their  agreement  and  intended  to be a  complete  and
          exclusive  statement of the agreement and understanding of the parties
          hereto in respect of the subject matter contained herein. There are no
          restrictions,  promises, warranties or undertakings,  other than those
          set forth or referred to herein.  This Agreement  supersedes all prior
          agreements and understandings between the parties with respect to such
          subject matter,  except for provisions in other agreements between the
          parties dealing with  confidentiality and the protection of employees,
          which provisions shall continue in full force and effect independently
          of this Agreement.

     (h)  Attorney's  Fees. In any action or  proceeding  brought to enforce any
          provision of this  Agreement or an arbitration  award,  the successful
          party  shall be  entitled  to recover  reasonable  attorneys'  fees in
          addition to its costs and expenses and any other available remedy.

     (i)  Amendment.  This  Agreement  may be amended only by means of a written
          amendment signed by the Company and UtiliCorp.

     (j)  No Presumption.  In the event any claim is made by a party relating to
          any conflict, omission, or ambiguity in this Agreement, no presumption
          or burden of

                                       6

          proof or  persuasion  shall be implied by virtue of the fact that this
          Agreement  was prepared by or at the request of a particular  party or
          its counsel.

     (k)  References  to this  Agreement.  References  to  numbered  or lettered
          articles,  section, and subsections refer to articles,  sections,  and

                               REGISTRATION RIGHTS

     Section 2.1 Demand Registration.

          (a) Request for  Registration.  After the  expiration  of 180 calendar
     days  after the  Closing  Date,  any  Holder or  Holders  who  collectively
     Beneficially Own at least 50% of the Registrable  Securities may request (a
     "Request  Notice") the Company to register  under the Securities Act all or
     any portion of the  Registrable  Securities that are held by such Holder or
     Holders  (collectively,  the  "Requesting  Holder")  for sale in the manner
     specified in the Request Notice.

          (b) Company's  Obligations.  Promptly  following  receipt of a Request
     Notice,  the Company  shall (i) notify each Holder  (except the  Requesting
     Holder)  of the  receipt  of a  Request  Notice  and  (ii)  shall  use  its
     commercially  reasonable  efforts to effect such  registration  (including,
     without limitation, preparing and filing a registration statement under the
     Securities  Act  (each  such   registration   statement,   a  "Registration
     Statement") effecting the registration under the Securities Act, for public
     sale in accordance with the method of disposition specified in such Request
     Notice) of the Registrable  Securities specified in the Request Notice (and
     in any notices that the Company  receives  from other Holders no later than
     the 15th  calendar  day after  receipt of the notice  sent by the  Company)
     (such other Holders and the Requesting Holders, the "Requesting  Holders").
     If such method of disposition shall be an underwritten public offering, the
     Company may designate the managing underwriter of such offering, subject to
     the  approval  of  the  Requesting   Holders  holding  a  majority  of  the
     Registrable  Securities  to be  registered,  which  approval  shall  not be
     withheld   unreasonably.   The  Company  shall  be  obligated  to  register
     Registrable Securities pursuant to this Section 2.1 on one occasion only.

          (c) Deferral by Company. If the Company has received a Request Notice,
     whether or not a Registration Statement with respect thereto has been filed
     or has become  effective,  or an event  referred  to in Section  2.3(e) has
     occurred,  and the Company furnishes to the Requesting  Holders a copy of a
     resolution  of the  Board of  Directors  of the  Company  certified

                                       4
<PAGE>

     by the Secretary of the Company  stating that in the good faith judgment of
     the  Board  of  Directors  it  would  not be in the  best  interest  of the
     Company's  stockholders for such Registration  Statement (i) to be filed on
     or before the date such filing would otherwise be required hereunder,  (ii)
     to become effective or (iii) to be updated by  post-effective  amendment or
     prospectus  supplement  because (A) such action would materially  interfere
     with a significant  acquisition,  corporate reorganization or other similar
     transaction  involving the Company, (B) such action would require premature
     disclosure  of  material  information  that  the  Company  has a bona  fide
     business  purpose for  preserving  as  confidential,  or (C) the Company is
     unable to comply with  requirements  of the  Commission,  the Company shall
     have the right,  but not more than once in any 365-day  period with respect
     to any  Request  Notice,  to defer such  filing or  effectiveness  for such
     period as may be  reasonably  necessary  (which  period  shall not,  in any
     event,  exceed 90  calendar  days  from the date the  response  period  for
     Holders pursuant to Section 2.1(b) expires).

          (d) Participation  Rights of Company and Others.  The Company shall be
     entitled to include in any  Registration  Statement  filed pursuant to this
     Section  2.1,  for  sale in  accordance  with  the  method  of  disposition
     specified by the Requesting  Holder,  securities of the Company entitled to
     vote generally in the election of directors (or any securities  convertible
     into or  exchangeable  for or exercisable for the purchase of securities so
     entitled  generally  to vote in the election of  directors)  (collectively,
     "Voting Securities") to be sold by the Company for its own account,  except
     as and to the extent that, in the opinion of the managing  underwriter  (if
     such method of disposition shall be an underwritten public offering),  such
     inclusion  would  materially  jeopardize  the  successful  marketing of the
     Registrable  Securities  to be sold.  Any Person  other than a Holder  (the
     "Other Holders") entitled to piggy-back registration rights with respect to
     a  Registration  Statement  filed  pursuant to this Section 2.1 may include
     Voting Securities of the Company with respect to which such rights apply in
     such  Registration  Statement  for sale in  accordance  with the  method of
     disposition  specified by the Requesting  Holder,  except and to the extent
     that,  in the  opinion  of the  managing  underwriter  (if such  method  of
     disposition shall be an underwritten public offering), such inclusion would
     materially   jeopardize  the  successful   marketing  of  the   Registrable
     Securities  to be sold.  Except as provided in this  subsection  (d) and in
     Section  2.6 of this  Agreement,  the  Company  will not  effect  any other
     registration of its Voting Securities  (except with respect to Registration
     Statements  (i) on Form  S-4 or S-8 or any  forms  succeeding  thereto  for
     purposes  permissible  under such forms as of the date hereof or (ii) filed
     in connection with an exchange offer or an offering of securities solely to
     the Company's existing  stockholders or such other Registration  Statements
     (A) for the resale of shares issued pursuant to an employee stock ownership
     trust or other benefit plan of a business acquired in an acquisition by the
     Company or (B) in connection  with  non-underwritten  resales of securities
     issued to owners of a business  acquired in an acquisition by the Company),
     whether for its own account or that of any Other  Holder other than holders
     of  "Registerable  Securties"  (as such  term is  defined  in that  certain
     Registration  Rights  Agreement,  dated  September 29, 1998,  between Joint
     Energy  Development  Investments  II Limited  Partnership,  Enron Capital &
     Trade Resources Corp. and the Company,  as amended (the "Enron Registration
     Rights  Agreement"))  under the Enron  Registration  Rights  Agreement (the
     "Enron  Holders"),  from the date of receipt of a Request Notice requesting
     the registration of an underwritten public offering until the completion or
     abandonment  of the  distribution  by the  underwriters  of all  securities
     thereunder;  provided,  however,  such  restricted  period shall not extend
     beyond the date 90 calendar days  subsequent to the effective  date of such
     Registration Statement.

                                       5
<PAGE>

          (e)  Prohibition  on  Future  Grants.  From and after the date of this
     Agreement  and until no  Registrable  Securities  remain  outstanding,  the
     Company shall not grant any demand registration rights to any Person unless
     such  rights are  expressly  made  subject  to the right of the  Holders to
     include an equal number of shares of the Registrable  Securities along with
     the other Person's shares in any  registration  relating to an underwritten
     public  offering,  except and to the  extent  that,  in the  opinion of the
     managing  underwriter,   the  inclusion  of  all  shares  requested  to  be
     registered by all Persons holding  registration  rights,  would  materially
     jeopardize  the  successful  marketing  of the  securities  (including  the
     Registrable Securities) to be sold.

     Section 2.2 Piggy-Back Registration.

          (a) Company  Notice.  If the Company  proposes to register  any Voting
     Securities  under  the  Securities  Act for sale to the  public  for  cash,
     whether  for its own  account or for the  account of Other  Holders or both
     (except with respect to Registration  Statements on Forms S-4 or S-8 or any
     forms succeeding  thereto for purposes  permissible  under such forms as of
     the date  hereof  or  filed  in  connection  with an  exchange  offer or an
     offering of securities solely to the Company's existing stockholders), each
     such time it will give written notice to all Holders of its intention to do
     so no less than 20 calendar days prior to the anticipated filing date.

          (b) Request.  Upon the written  request of any Holder  received by the
     Company no later than the 15th calendar day after receipt by such Holder of
     the  notice  sent by the  Company,  to  register,  on the  same  terms  and
     conditions  as  the  securities  otherwise  being  sold  pursuant  to  such
     registration,  any of its Registrable Securities (which request shall state
     the  intended  method of  disposition  thereof),  the Company  will use its
     commercially  reasonable efforts to cause the Registrable  Securities as to
     which  registration  shall have been so  requested  to be  included  in the
     securities to be covered by the Registration Statement proposed to be filed
     by the Company,  on the same terms and conditions as any similar securities
     included  therein,  all to the extent requisite to permit the sale or other
     disposition by each Holder (in accordance with its written request) of such
     Registrable Securities so registered;  provided,  however, that the Company
     may at any time,  in its sole  discretion  and  without  the consent of any
     Holder,  abandon the proposed offering in which any Holder had requested to
     participate.

          (c) Underwriter's Cut-Back. The number of Registrable Securities to be
     included in such a registration  may be reduced or eliminated if and to the
     extent, in the case of an underwritten  offering,  the managing underwriter
     shall  render  to  the  Company  its  opinion  that  such  inclusion  would
     materially jeopardize the successful marketing of the securities (including
     the Registrable Securities) proposed to be sold therein; provided, however,
     that (a) in the case of a  Registration  Statement  filed  pursuant  to the
     exercise of demand registration rights of any Other Holders, priority shall
     be given in the following  manner of  allocation:  (i) first,  to the Other
     Holders   demanding   such   registration;   (ii)   then   equally   (on  a
     share-for-share  basis) to the Holders and Enron Holders; (iii) then to the
     Company;  and (iv)  then to Other  Holders  or  other  stockholders  of the
     Company desiring to participate with the Company's  consent (other than the
     Other Holders entitled to participate under clause (i) or (ii)), and (b) in
     the case of a  Registration  Statement  the filing of which is initiated by
     the Company,  priority shall be given in the following order of allocation:
     (i) first to the Company and (ii) then equally (on a share-for-share basis)
     to the  Holders  and  Other  Holders.  In the  event  that  the  number  of
     Registrable Securities to be included in a registration is to be reduced as
     provided  above,  within 10  business

                                       6
<PAGE>

     days after receipt by each Holder proposing to sell Registrable  Securities
     pursuant  to the  registered  offering  of the  opinion  of  such  managing
     underwriter,  all such Selling  Holders may allocate  among  themselves the
     number of shares of such  Registrable  Securities which such opinion states
     may be distributed  without  adversely  affecting the  distribution  of the
     securities covered by the Registration Statement or, if less, the number of
     such shares allocable to Holders of Registrable  Securities after reduction
     for any  allocations to the Company or Other Holders in accordance with the
     priority  provisions  set  forth  in the  preceding  sentence,  and if such
     Holders  are  unable  to  agree  among  themselves  with  respect  to  such
     allocation,  such allocation  shall be made in proportion to the respective
     numbers of shares specified in their respective written requests.

          (d)  Prohibition  on  Future  Grants.  From and after the date of this
     Agreement  and until no  Registrable  Securities  remain  outstanding,  the
     Company shall not grant any  piggy-back  registration  rights to any Person
     unless such rights are expressly made subject to the prior right of Holders
     to  include  their  Registrable  Securities  on a  pro-rata  basis  in  any
     registration relating to an underwritten public offering, except and to the
     extent that, in the opinion of the managing  underwriter,  the inclusion in
     the  offering  of all shares  requested  to be  registered  by all  Persons
     holding  registration  rights would  materially  jeopardize  the successful
     marketing of the securities  (including the  Registrable  Securities) to be
     sold.

     Section  2.3  Registration  Procedures.  If and  whenever  the  Company  is
required  pursuant to this  Agreement to effect the  registration  of any of the
Registrable   Securities   under  the  Securities  Act,  the  Company  will,  as
expeditiously as possible:

          (a)  prepare  and file as promptly  as  reasonably  possible  with the
     Commission a  Registration  Statement,  on a form available to the Company,
     with  respect to such  securities  (which  filing  shall be made  within 30
     calendar days after the receipt by the Company of a Request Notice) and use
     its commercially reasonable efforts to cause such Registration Statement to
     become and remain effective for the period of the distribution contemplated
     thereby (determined pursuant to subsection (g) below);

          (b)  prepare  and  file  with  the  Commission   such  amendments  and
     supplements  to such  Registration  Statement  and the  prospectus  used in
     connection  therewith  as  may  be  necessary  to  keep  such  Registration
     Statement  effective for the distribution  period  (determined  pursuant to
     subsection (g) below) and as may be necessary to comply with the provisions
     of the  Securities  Act with respect to the  disposition  of all securities
     covered by such Registration Statement;

          (c) furnish to each Selling Holder and to each underwriter such number
     of copies of the Registration Statement and the prospectus included therein
     (including each  preliminary  prospectus and each document  incorporated by
     reference  therein to the extent then required by the rules and regulations
     of the  Commission)  as such  Persons  may  reasonably  request in order to
     facilitate  the  public  sale  or  other  disposition  of  the  Registrable
     Securities covered by such Registration Statement;

          (d) if applicable, use its commercially reasonable efforts to register
     or  qualify  the  Registrable   Securities  covered  by  such  Registration
     Statement  under the securities or blue sky laws of such  jurisdictions  as
     the Selling Holders or, in the case of an underwritten public

                                       7
<PAGE>

     offering, the managing underwriter, shall reasonably request, provided that
     the Company will not be required to qualify  generally to transact business
     in any jurisdiction  where it is not then required to so qualify or to take
     any action which would subject it to general service of process in any such
     jurisdiction where it is not then so subject;

          (e) immediately  notify each Selling Holder and each  underwriter,  at
     any time when a  prospectus  relating  thereto is required to be  delivered
     under the  Securities  Act,  of the  happening  of any event as a result of
     which the prospectus contained in such Registration  Statement,  as then in
     effect,  includes an untrue  statement of a material fact or omits to state
     any material  fact  required to be stated  therein or necessary to make the
     statements  therein not misleading in the light of the  circumstances  then
     existing and as promptly as practicable  amend or supplement the prospectus
     or take other appropriate action so that the prospectus does not include an
     untrue  statement  of a  material  fact or omit to  state a  material  fact
     required to be stated therein or necessary to make the  statements  therein
     not misleading in the light of the circumstances then existing;

          (f) in the  case of an  underwritten  public  offering,  furnish  upon
     request,  (i) on the date that Registrable  Securities are delivered to the
     underwriters for sale pursuant to such Registration  Statement,  an opinion
     of  counsel  for the  Company  dated as of such date and  addressed  to the
     underwriters  and to the Selling  Holders,  stating that such  Registration
     Statement has become effective under the Securities Act and that (A) to the
     best knowledge of such counsel,  no stop order suspending the effectiveness
     thereof  has been  issued and no  proceedings  for that  purpose  have been
     instituted or are pending or contemplated under the Securities Act, (B) the
     Registration  Statement,  the related  prospectus,  and each  amendment  or
     supplement  thereof  comply as to form in all  material  respects  with the
     requirements of the Securities Act and the applicable rules and regulations
     thereunder  of the  Commission  (except  that such  counsel need express no
     opinion as to the financial statements,  or any expertized schedule, report
     or  information  contained or  incorporated  therein) and (C) to such other
     effects as may reasonably be requested by counsel for the underwriters, and
     (ii) on the effective  date of the  Registration  Statement and on the date
     that  Registrable  Securities  are delivered to the  underwriters  for sale
     pursuant to such Registration Statement, a letter dated such dates from the
     independent   accountants  retained  by  the  Company,   addressed  to  the
     underwriters and, if available,  to the Selling Holders,  stating that they
     are independent public accountants within the meaning of the Securities Act
     and that, in the opinion of such accountants,  the financial  statements of
     the Company and the schedules  thereto that are included or incorporated by
     reference in the Registration Statement or the prospectus, or any amendment
     or supplement thereof,  comply as to form in all material respects with the
     applicable  requirements  of the Securities Act and the published rules and
     regulations  thereunder,  and such letter shall  additionally  address such
     other financial matters  (including  information as to the period ending no
     more than five business days prior to the date of such letter)  included in
     the  Registration  Statement in respect of which such letter is being given
     as the underwriters may reasonably request;

          (g) make available for inspection by one representative of the Selling
     Holders, designated by a majority thereof, any underwriter participating in
     any distribution pursuant to such Registration Statement, and any attorney,
     accountant or other agent  retained by such  representative  of the Selling
     Holders or underwriter (the "Inspectors"), all financial and other records,
     pertinent corporate documents and properties of the Company  (collectively,
     the

                                       8
<PAGE>

     "Records"),  and cause the Company's  officers,  directors and employees to
     supply  all  information  reasonably  requested  by any such  Inspector  in
     connection with such Registration Statement;  provided,  however, that with
     respect to any Records that are  confidential,  the  Inspectors  shall take
     such action as the Company may reasonably  request in order to maintain the
     confidentiality  of the Records.  For purposes of  subsections  (a) and (b)
     above with respect to demand  registration only, the period of distribution
     of Registrable Securities in a firm commitment underwritten public offering
     shall  be  deemed  to  extend  until  the  earlier  of (a)  the  date  each
     underwriter has completed the  distribution of all securities  purchased by
     it or (b) the date 90 calendar days  subsequent  to the  effective  date of
     such Registration Statement,  and the period of distribution of Registrable
     Securities  in any other  registration  shall be deemed to extend until the
     earlier of the sale of all  Registrable  Securities  covered thereby or one
     year;

          (h) cause all such Registrable  Securities registered pursuant to this
     Agreement  to be  listed  on each  securities  exchange  on  which  similar
     securities issued by the Company are then listed;

          (i) use its  commercially  reasonable  efforts to keep  effective  and
     maintain  for  the  period  specified  in  subsection  (g) a  registration,
     qualification,  approval  or  listing  obtained  to cover  the  Registrable
     Securities as may be necessary for the Selling  Holders to dispose  thereof
     and shall  from time to time amend or  supplement  any  prospectus  used in
     connection  therewith  to the  extent  necessary  in order to  comply  with
     applicable law;

          (j) use its commercially  reasonable  efforts to cause the Registrable
     Securities  to be  registered  with or approved by such other  governmental
     agencies or  authorities  as may be necessary by virtue of the business and
     operations of the Company to enable the Selling  Holders to consummate  the
     disposition of such Registrable Securities; and

          (k) enter into customary agreements and take such other actions as are
     reasonably requested by the Selling Holders or the underwriters, if any, in
     order  to  expedite  or  facilitate  the  disposition  of such  Registrable
     Securities.

     Each  Selling  Holder,  upon  receipt  of notice  from the  Company  of the
happening of any event of the kind  described in subsection  (e) of this Section
2.3, shall forthwith discontinue disposition of the Registrable Securities until
such  Selling  Holder's  receipt  of the copies of the  supplemented  or amended
prospectus  contemplated  by  subsection  (e) of this Section 2.3 or until it is
advised in writing by the Company that the use of the prospectus may be resumed,
and has received  copies of any  additional  or  supplemental  filings which are
incorporated by reference in the prospectus, and, if so directed by the Company,
such  Selling  Holder  will,  or  will  request  the  managing   underwriter  or
underwriters,  if any, to deliver to the Company (at the Company's  expense) all
copies in their possession or control,  other than permanent file copies then in
such Selling Holder's  possession,  of the prospectus  covering such Registrable
Securities  current at the time of receipt of such notice.  If the Company shall
give any such notice,  the time  periods  mentioned  in  subsection  (g) of this
Section  2.3 shall be  extended by the number of days during the period from and
including  the date of the giving of such notice to and  including the date when
each  Selling  Holder  shall have  received  the copies of the  supplemented  or
amended prospectus  contemplated by subsection (e) of this Section 2.3 hereof or
the notice that they may resume use of the prospectus.

<PAGE>

     In  connection  with  each  registration   hereunder  with  respect  to  an
underwritten  public  offering,  the Company and each Selling  Holder  agrees to
enter into a written  agreement with the managing  underwriter  or  underwriters
selected  in the  manner  herein  provided  in such  form  and  containing  such
provisions as are customary in the  securities  business for such an arrangement
between underwriters and companies of the Company's size and investment stature.

     Section 2.4  Cooperation  by Selling  Holders.  The  Company  shall have no
obligation to include in such Registration  Statement shares of a Selling Holder
who has failed to timely furnish such information  which, in the written opinion
of counsel to the Company,  is reasonably required in order for the Registration
Statement to comply with the Securities Act.

     Section 2.5  Restrictions  on Public Sale by Selling Holders of Registrable
Securities.  To the extent  not  inconsistent  with  applicable  law,  including
insurance codes, each Selling Holder of Registrable  Securities that is included
in a Registration  Statement which registers Registrable  Securities pursuant to
this Agreement agrees not to effect any public sale or distribution of the issue
being  registered  (or  any  securities  of  the  Company  convertible  into  or
exchangeable  or exercisable  for securities of the same type as the issue being
registered)  during the 14 business days before,  and during the 90 calendar day
period beginning on, the effective date of a Registration Statement filed by the
Company  (except  as part of such  registration),  but only if and to the extent
requested in writing (with reasonable prior notice) by the managing  underwriter
or underwriters in the case of an underwritten public offering by the Company of
securities  of the same type as the  Registrable  Securities,  provided that the
duration of the foregoing  restrictions  shall be no longer than the duration of
the  shortest  restriction  imposed  by  the  underwriters  on the  officers  or
directors  or any other  stockholder  of the  Company on whom a  restriction  is
imposed;  and,  provided  further that to the extent the Selling  Holders do not
participate in the underwritten  public  offering,  the period of time for which

     Section 2.8 Indemnification.

          (a) By the Company.  In the event of a registration of any Registrable
     Securities under the Securities Act pursuant to this Agreement, the Company
     will  indemnify and hold harmless each Selling  Holder  thereunder and each
     underwriter,  pursuant to the applicable  underwriting  agreement with such
     underwriter,  of Registrable Securities thereunder and each Person, if any,
     who controls such Selling Holder or  underwriter  within the meaning of the
     Securities Act and the Exchange Act, against any losses, claims, damages or
     liabilities   (including   reasonable   attorneys'   fees)   (collectively,
     "Losses"), joint or several, to which such Selling Holder or underwriter or
     controlling  Person  may  become  subject  under the  Securities  Act,  the
     Exchange  Act or  otherwise,  insofar as such Losses (or actions in respect
     thereof)  arise out of or are based  upon any untrue  statement  or alleged
     untrue  statement  of any  material  fact  contained  in  any  Registration
     Statement under which such Registrable Securities were registered under the
     Securities Act pursuant to this Agreement,  any  preliminary  prospectus or
     final prospectus contained therein, or any amendment or supplement thereof,
     or arise out of or are based upon the omission or alleged omission to state
     therein a material fact required to be stated  therein or necessary to make
     the statements therein not misleading, and will reimburse each such Selling
     Holder,  each such  underwriter  and each such  controlling  Person for any
     legal or other  expenses  reasonably  incurred by them in  connection  with
     investigating  or defending  any such Loss or actions;  provided,  however,
     that the  Company  will not be liable in any such case if and to the extent
     that any such loss,  claim,  damage or liability  arises out of or is based
     upon an untrue statement or alleged untrue statement or omission or alleged
     omission so made in conformity with  information  furnished by such Selling
     Holder, such underwriter or such controlling Person in writing specifically
     for use in such Registration Statement or prospectus.

          (b) By the Selling Holder(s).  Each Selling Holder agrees to indemnify
     and hold  harmless the Company,  its  directors,  officers,  employees  and
     agents and each Person, if any, who controls the Company within the meaning
     of the  Securities  Act or of the  Exchange  Act to the same  extent as the
     foregoing  indemnity from the Company to such Selling Holder, but only with
     respect to information  regarding such Selling Holder  furnished in writing
     by or on behalf of such  Selling  Holder  expressly  for  inclusion  in any
     Registration   Statement  or   prospectus   relating  to  the   Registrable
     Securities, or any amendment or supplement thereto; provided, however, that
     the  liability of such  Selling  Holder shall not be greater in amount than
     the dollar

                                       11
<PAGE>

     amount of the  proceeds  (net of any  Selling  Expenses)  received  by such
     Selling Holder from the sale of the Registrable  Securities  giving rise to
     such indemnification.

          (c) Notice.  Promptly after receipt by an indemnified  party hereunder
     of notice of the commencement of any action,  such indemnified party shall,
     if a claim in respect thereof is to be made against the indemnifying  party
     hereunder,  notify  the  indemnifying  party in  writing  thereof,  but the
     omission so to notify the indemnifying  party shall not relieve it from any
     liability which it may have to any indemnified  party other than under this
     Section 2.8. In any action brought against any indemnified  party, it shall
     notify the indemnifying party of the commencement thereof. The indemnifying
     party shall be entitled to participate in and, to the extent it shall wish,
     to assume  and  undertake  the  defense  thereof  with  counsel  reasonably
     satisfactory  to  such  indemnified   party  and,  after  notice  from  the
     indemnifying  party to such indemnified  party of its election so to assume
     and  undertake the defense  thereof,  the  indemnifying  party shall not be
     liable to such  indemnified  party  under  this  Section  2.8 for any legal
     expenses subsequently incurred by such indemnified party in connection with
     the defense thereof other than  reasonable  costs of  investigation  and of
     liaison with  counsel so  selected;  provided,  however,  that,  (i) if the
     indemnifying  party has failed to assume the defense and employ  counsel or
     (ii) if the  defendants  in any such action  include  both the  indemnified
     party and the indemnifying party and counsel to the indemnified party shall
     have  concluded  that there may be  reasonable  defenses  available  to the
     indemnified  party that are different from or additional to those available
     to the  indemnifying  party or if the  interests of the  indemnified  party
     reasonably may be deemed to conflict with the interests of the indemnifying
     party, then the indemnified party shall have the right to select a separate
     counsel and to assume such legal  defense and otherwise to  participate  in
     the defense of such action,  with the reasonable  expenses and fees of such
     separate   counsel   and  other   reasonable   expenses   related  to  such
     participation to be reimbursed by the indemnifying party as incurred.

          (d) Contribution.  If the indemnification provided for in this Section
     2.8 is held by a court or government agency of competent jurisdiction to be
     unavailable  to the Company or the Selling  Holders or is  insufficient  to
     hold them  harmless in respect of any Losses,  then each such  indemnifying
     party, in lieu of indemnifying such indemnified  party, shall contribute to
     the amount  paid or payable by such  indemnified  party as a result of such
     Losses as between  the Company on the one hand and each  Selling  Holder on
     the other,  in such  proportion as is  appropriate  to reflect the relative
     fault of the  Company  on the one hand and of each  Selling  Holder  on the
     other in connection with the statements or omissions which resulted in such
     Losses as well as any other relevant  equitable  considerations;  provided,
     however,  that in no event shall a Selling Holder be required to contribute
     an  aggregate  amount in excess of the dollar  amount of  proceeds  (net of
     Selling  Expenses)  received  by  such  Selling  Holder  from  the  sale of
     Registrable  Securities giving rise to such  indemnification.  The relative
     fault of the Company on the one hand and each  Selling  Holder on the other
     shall be determined by reference to, among other things, whether the untrue
     or alleged  untrue  statement of a material fact or the omission or alleged
     omission  to state a  material  fact  has been  made  by,  or  relates  to,
     information  supplied  by such party,  and the  parties'  relative  intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission.  No person  guilty of  fraudulent  misrepresentation
     (within  the  meaning  of  Section  11(f) of the  Securities  Act) shall be
     entitled  to  contribution  from  any  Person  who is not  guilty  of  such
     fraudulent misrepresentation.

benefits of certain rules and  regulations of the Commission that may permit the
sale of the  Registrable  Securities  to the public  without  registration,  the
Company agrees to use commercially reasonable efforts to:

     and of the  Securities  Act and the Exchange Act, a copy of the most recent
     annual or  quarterly  report of the  Company,  and such other  reports  and
     documents so filed as a Holder may reasonably request in availing itself of
     any rule or regulation of the Commission allowing a Holder to sell any such
     securities without registration.

     Section 2.10 Transfer or Assignment of Registration  Rights.  The rights to
cause the Company to register Registrable Securities granted to UtiliCorp by the
Company under this Article II may be  transferred  or assigned by UtiliCorp to a
transferee or assignee of such  Registrable  Securities  that is an Affiliate of
UtiliCorp,  provided  that the  Company is given  written  notice  prior to said
transfer  or  assignment,  stating the name and  address of such  Affiliate  and
identifying  the securities with respect to which such  registration  rights are
being transferred or assigned, and, provided further, that the Affiliate assumes
in writing the obligations of UtiliCorp under this Agreement.  Such registration
rights shall not otherwise be transferable.

     Section 2.11 Registrable  Securities Held by the Company or Its Affiliates.
In  determining  whether  the  Holders  of the  required  amount of  Registrable
Securities  have concurred in any direction,  amendment,  supplement,  waiver or
consent,  Registrable  Securities  owned by the Company or one of its Affiliates
shall be disregarded.

                                  ARTICLE III
                                PRE-EMPTIVE RIGHT

     Section 3.1 Pre-Emptive  Right.  Subject to Section 3.5 hereof, the Company
hereby grants to each Holder (the "Pre-Emptive Purchasers") an irrevocable right
to purchase a  Proportionate  Number (as defined in Section 3.2(a)) of shares of
Common Stock in respect of the issuance or sale (or deemed  issuance or sale) by
the Company, from time to time during each fiscal quarter of the Company, of New
Securities to third parties (the  "Pre-Emptive  Right").  The Pre-Emptive  Right
shall be subject to the following provisions of this Article III.

     Section 3.2 Certain Definitions and Determinations.

          (a)  Proportionate  Number.  The  "Proportionate  Number" of shares of
     Common Stock that may be purchased by a Pre-Emptive Purchaser in respect of
     the applicable

                                       13
<PAGE>

     fiscal quarter shall be determined by  multiplying  (as to each issuance or
     sale to each third party) (i) the number of New  Securities  (as defined in
     Section  3.2(b))  issued  or sold (or  deemed  to be issued or sold) by the
     Company to such third party during such  applicable  fiscal  quarter of the
     Company  times (ii) a fraction of which (A) the  numerator is the number of
     Conversion  Shares  (on an as  converted  basis)  owned by the  Pre-Emptive
     Purchaser  on the date on which the  shares of  Preferred  Stock were first
     issued  (collectively,  the "Then Existing Shares") and (B) the denominator
     is the total number of shares of Common Stock  outstanding  (assuming  full
     conversion  of all  outstanding  securities  and the full  exercise  of all
     outstanding  options,  rights,  and warrants to acquire Common Stock of the
     Company)  on the date on which the  shares of  Preferred  Stock  were first
     issued.  For purposes of this Article III, if the Pre-Emptive  Purchaser is
     not the original holder of the shares of Preferred  Stock,  then the number
     of  Conversion  Shares  (on an as  converted  basis)  deemed  owned by such
     Pre-Emptive  Purchaser on the date on which the shares of  Preferred  Stock
     were  first  issued  shall be the  number of  Conversion  Shares  (on an as
     converted  basis) it acquired from the original holder or other  transferor
     at  any  time  (but  without  duplication  for  successive   transfers  and
     retransfers of the same shares).

          (b) "New  Securities"  shall  mean (i) any  Voting  Capital  Stock (as
     defined in Section  3.2(c) below) of the Company  whether now authorized or
     not and (ii) in the case of the  issuance  or sale of rights,  options,  or
     warrants to purchase such Voting Capital Stock,  and securities of any type
     whatsoever that are, or may become,  convertible  into Voting Capital Stock
     (collectively,  "Capital  Stock  Equivalents"),  the Voting  Capital  Stock
     issued upon the exercise or conversion  of such Capital Stock  Equivalents;
     provided  that the term "New  Securities"  does not include (i)  securities
     purchased under the Securities Purchase Agreement; (ii) securities issuable
     upon conversion or exercise of the Preferred Stock; (iii) securities issued
     in connection with any stock split, stock dividend or  recapitalization  of
     the Company;  (iv)  securities  issued upon  conversion  or exercise of any
     currently  outstanding Capital Stock Equivalents;  or (v) securities issued
     upon  conversion  or  exercise  of any  Capital  Stock  Equivalents  if the
     Pre-Emptive  Right was provided  upon the  issuance of such  Capital  Stock
     Equivalent.

          (c) "Voting  Capital  Stock" shall mean Common Stock or other  capital
     stock which is entitled to vote  generally  with the Common  Stock upon the
     election of  directors  and other  matters  submitted  to a general vote of
     stockholders.

     sale  price per  share of the  Common  Stock on such date on the  principal
     stock exchange on which the Common Stock has been listed or, if there is no
     such price on such date,  then the last sale price on such  exchange on the
     date nearest preceding such date, (ii) if the Common Stock is not listed on
     any stock exchange,  the final bid price for a share of Common Stock in the
     over-the-counter  market,  as  reported  by  the  National  Association  of
     Securities  Dealers  Automated  Quotation System ("NASDAQ") at the close of
     business  on such date,  or the last sales  price if such price is reported
     and final bid prices are not  available,  (iii) if the Common  Stock is not
     quoted on the  NASDAQ,  the bid  price  for a share of Common  Stock in the
     over-the-counter  market  as  reported  by the  National  Quotation  Bureau
     Incorporated  (or any  similar  organization  or agency  succeeding  to its
     functions  of reporting  prices),  or (iv) if the Common Stock is no longer
     publicly  traded,  as determined in good faith by the Board of Directors of
     the Company  based upon the price that would be paid by a willing  buyer of
     the shares at issue,  in a sale  process  designed

                                       14
<PAGE>

     to  maximize  value and  attract a  reasonable  number of  participants  to
     provide a fair determination of such value.

     Section  3.3  Mechanics.  In the event the  Company  issues or sells (or is
deemed to issue or sell) New Securities,  within two business days after the end
of such fiscal  quarter in which the New  Securities  were  issued or sold,  the
Company shall give each  Pre-Emptive  Purchaser  written notice of the issuance,
describing the type of New  Securities  issued or sold, the date of the issuance
or sale (or deemed  issuance  or sale),  the  Proportionate  Number of shares of
Common Stock related to the New Securities that it may acquire and the aggregate
purchase price payable by it upon exercise of its Pre-Emptive  Right  (including
relevant  details as to the  calculation of such purchase  price).  The purchase
price for each such share of Common Stock shall be equal to the Closing Price of
the Common Stock on the date of issuance or sale (or deemed issuance or sale) of
the  corresponding New Security.  Each Pre-Emptive  Purchaser shall exercise its
Pre-Emptive  Right (if at all) by delivering,  within 10 business days after the
end of such fiscal quarter in which the New  Securities  were issued or sold (or
deemed to be issued or sold,  (a)  notice to the  Company  stating  therein  the
quantity of its  Proportionate  Number of shares of Common Stock to be purchased
and (b) payment to the Company of the aggregate  purchase  price for such shares
in immediately available funds. Thereupon,  the Company shall promptly issue and
deliver such Pre-Emptive  Purchaser a certificate or certificates for the number
of shares of Common Stock related to the New  Securities  which the  Pre-Emptive
Purchaser has elected to purchase.

     Section 3.4 Adjustments.  The applicable  purchase price and each component
of the definition of  Proportionate  Number shall be adjusted  appropriately  to
reflect stock dividends,  combinations,  splits,  reclassifications,  exchanges,
substitutions  or other similar  adjustments  with respect to the New Securities
issued  during the relevant  fiscal  quarter that occur prior to the exercise of
the applicable Pre-Emptive Right.

     Section 3.5 Transfer of Pre-Emptive  Right. The Pre-Emptive Right set forth
in this  Article  III may be  transferred  or assigned  by  UtiliCorp  only to a
transferee  or assignee of the Then  Existing  Shares  that is an  Affiliate  of
UtiliCorp,  provided  that the  Company is given  written  notice  prior to said
transfer  or  assignment,  stating  the name and  address or the  Affiliate  and
identifying  the securities  with respect to which such  Pre-Emptive  Rights are
being transferred or assigned, and, provided further, that the Affiliate of such
rights assumes in writing the  obligations of such  Pre-Emptive  Purchaser under
this Agreement.

     Section 3.6 Termination of Pre-Emptive Right. The Pre-Emptive Right granted
under this Agreement  shall terminate on the first to occur of (a) expiration of
the 10-day  exercise  period  after a fiscal  quarter  in which the  Pre-Emptive
Purchaser fails to exercise its Pre-Emptive Right in full or (b) the Pre-Emptive
Purchaser's  voluntary  or  involuntary,  direct  or  indirect  transfer,  sale,
assignment,  donation,  pledge or other  encumbrance  of any shares of Preferred
Stock or Conversion Shares (except to an Affiliate).

          (b) Such  Holder  shall have  notified  the  Company  of the  proposed
     disposition and shall have furnished the Company with a detailed  statement
     of  the  circumstances   surrounding  the  proposed  disposition,   and  if
     reasonably  requested by the Company,  such Holder shall have furnished the
     Company with an opinion of counsel, reasonably satisfactory to the Company,
     that such disposition is exempt from registration under the Securities Act;
     provided  however,  that it is agreed  that the  Company  will not  require
     opinions of Holder's  counsel for  transactions  made  pursuant to Rule 144
     except in unusual circumstances.

STATE  SECURITIES  LAW OR UNLESS THE COMPANY HAS  RECEIVED AN OPINION OF COUNSEL
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED TO EFFECTUATE
SUCH TRANSACTION.

THE SALE,  TRANSFER  OR PLEDGE OF THIS  CERTIFICATE  IS SUBJECT TO THE TERMS AND
CONDITIONS  OF A CERTAIN  INVESTOR'S  RIGHTS  AGREEMENT  BETWEEN THE COMPANY AND
CERTAIN HOLDERS OF ITS SECURITIES, AS THE SAME MAY BE AMENDED AND IN EFFECT FROM

     counsel to the Company) reasonably  acceptable to the Company to the effect
     that the securities  proposed to be disposed of may lawfully be so disposed
     of under Rule 144(k) (or any successor thereto or substantially  equivalent
     exemption) without registration, qualification or legend.

     Section 4.5 Improper Transfer.  Any attempt to Transfer any Preferred Stock
which is not in accordance  with this Agreement  shall be null and void, and the
Company shall not give any effect to such  attempted  Transfer in the records of
the Company.

                                  MISCELLANEOUS

     Section 5.1 Dispute Resolution.  Any action,  dispute, claim or controversy
of any kind now existing or hereafter  arising  between the Company and a Holder
arising out of,  pertaining to this Agreement or the  transactions  contemplated
hereby (a "Dispute") shall be resolved by binding arbitration in accordance with
the terms  hereof.  Any party may,  by summary  proceedings,  bring an action in

administered by the American  Arbitration  Association (the "AAA") in accordance
with the terms of this Section,  the  Commercial  Arbitration  Rules of the AAA,
and, to the maximum extent applicable,  the Federal Arbitration Act. Judgment on
any  award  rendered  by an  arbitrator  may  be  entered  in any  court  having
jurisdiction.  Any  arbitration  shall  be  conducted  before  a panel  of three
arbitrators.  Such panel shall consist of one person  designated by the Company,
one  designated  by the Holder(s) and one  designated  by their  designees.  The
arbitrators designated by the parties are not required to be neutral. If a party
fails to designate an arbitrator within 10 calendar days after the filing of the
Dispute  with the AAA, or the  parties'  arbitrators  fail to  designate a third
arbitrator within 30 calendar days after the later of their  appointments,  such
arbitrator  shall be appointed by the AAA. An arbitration  proceeding  hereunder
shall be concluded  within 180  calendar  days of the filing of the Dispute with
the AAA.  Arbitration  proceedings shall be conducted in Kansas City,  Missouri.
Arbitrators shall be empowered to award sanctions and to take such other actions
as they deem  necessary,  to the same extent a judge could  impose  sanctions or
take such other  actions  pursuant to the Federal  Rules of Civil  Procedure and

               CERTIFICATE OF DESIGNATION, RIGHTS, AND LIMITATIONS
                   OF THE SERIES A CONVERTIBLE PREFERRED STOCK
                            OF QUANTA SERVICES, INC.


     Pursuant to Section  151(g),  The General  Corporation  Law of the State of
Delaware, Quanta Services, Inc., a Delaware corporation (the "Corporation"),

DOES HEREBY CERTIFY:

     That,  pursuant  to  authority  conferred  upon the Board of  Directors  by
Article  Fourth of the Amended and Restated  Certificate of  Incorporation,  and
pursuant  to the  provisions  of The  General  Corporation  Law of the  State of
Delaware,  the  Board of  Directors  on  September  21,  1999,  duly  adopted  a
resolution  providing for the issuance of series A convertible  preferred stock,
which resolution is as follows:

     RESOLVED,  that,  pursuant to the authority expressly granted and vested in
the Board of Directors of the  Corporation,  and  effective  upon filing of this
Certificate  of  Designation,  Rights,  and  Limitations  (the  "Certificate  of
Designation"),  there  shall be  designated  a "Series A  Convertible  Preferred
Stock" (the  "Series A Preferred  Stock"),  consisting  of  1,860,000  shares of
preferred stock of the Corporation, $0.00001 par value per share.

     FURTHER  RESOLVED,  that the Board of Directors be, and the same hereby is,
authorized  to issue such shares of Series A  Preferred  Stock from time to time
and for such  consideration  and on such terms as the Board of  Directors  shall
determine; and

     FURTHER RESOLVED,  that, subject to the limitations  provided by law and by
the Corporation's Amended and Restated Certificate of Incorporation, the powers,
designations, preferences and relative, participating, optional or other special
rights,  powers  or  priorities  of,  and  the  qualifications,  limitations  or
restrictions upon, the Series A Preferred Stock shall be as follows:

     1. Designation. One million eight hundred sixty thousand (1,860,000) shares
of the authorized and unissued preferred stock of the Corporation,  $0.00001 par
value per share, are hereby  designated  "Series A Convertible  Preferred Stock"
(the "Series A Preferred Stock").

     2. Dividends.

          (a) Preferred.  Subject to Sections 2(c) and (d) below, the holders of
     Series A Preferred Stock shall be entitled to receive  dividends in cash at
     the rate of 0.5% per annum on an amount  equal to  $100.00  (the  "Purchase
     Price"),  plus all unpaid dividends  accrued,  on each outstanding share of
     Series A  Preferred  Stock (as  adjusted  pursuant to Section 5 hereof with
     respect to such share),  when and as declared by the Board of Directors out
     of the funds legally available for that purpose (the "Preferred Dividend").
     The Preferred  Dividend on each share of Series A Preferred  Stock shall be
     cumulative from the date of issuance of such share,  whether or not earned,
     whether  or not funds of the  Corporation  are  legally  available  for the
     payment of dividends and whether or not declared by the Board of Directors,
     but such  dividend  shall be payable only when,  as, and if declared by the
     Board of Directors. So long as any shares of Series


<PAGE>

     A Preferred Stock shall be outstanding,  (i) no dividend,  whether in cash,
     stock  or  property,  shall  be paid  or  declared,  nor  shall  any  other
     distribution be made, on any shares of the common stock of the Corporation,
     par value  $0.00001 per share (the "Common  Stock"),  or any other class or
     series of  capital  stock of the  Corporation,  (ii) nor shall any class or
     series of  capital  stock of the  Corporation  be  redeemed,  purchased  or
     otherwise acquired for value by the Corporation (except for acquisitions of
     Common Stock by the Corporation pursuant to (A) agreements which permit the
     Corporation to repurchase  such shares upon  termination of services to the
     Corporation  entered  into on or  before  the date on which  the  shares of
     Series A Preferred  Stock were first issued (the "Original  Issue Date") or
     (B) in  satisfaction  of an  indemnification  obligation to the Corporation
     upon a breach by the holder of Common Stock of a  representation,  warranty
     or covenant in any agreement for the  acquisition  by the  Corporation of a
     business  (as  defined in Rule  11-01(d) of  Regulation  S-X adopted by the
     Securities  and  Exchange   Commission)   pursuant  to  the   Corporation's
     acquisition program (an "Acquisition")),  in each case, until all dividends
     set forth in this Section (2)(a) on the Series A Preferred Stock shall have
     been paid or declared and set apart.

          (b)  Participating.  In addition to the Preferred  Dividend payable on
     the Series A Preferred  Stock, the shares of Series A Preferred Stock shall
     be entitled to receive,  out of any funds legally available  therefor,  the
     amount of any cash or non-cash dividends or distributions declared and paid
     on the shares of Common Stock, as if the shares of Series A Preferred Stock
     had been converted immediately prior to the record date for payment of such
     dividends or distributions.

          (c) Corporation's Right to Terminate Preferred Dividend. At the option
     of the  Corporation  (exercisable  by  delivery  to the  holder  of  notice
     thereof),  at any time after the sixth  anniversary  of the Original  Issue
     Date, if on the date of exercise by the Corporation,  the Closing Price (as
     defined in Section  4(b)(i)  below) of the  Corporation's  Common  Stock is
     greater  than  $30.00   (subject  to   adjustment   for  any  stock  split,
     combination,  and  the  like),  then  the  Corporation  may  terminate  the
     Preferred  Dividend,  effective on the date of receipt by the holder of the
     relevant notice.

          (d)  Adjustment  of  Preferred  Dividend.  At the option of  UtiliCorp
     United Inc., a Delaware corporation, or one or more of its "affiliates" (as
     defined  in Rule  12b-2  under  the  Securities  Exchange  Act of 1934,  as
     amended) or all such persons together (collectively,  "UtiliCorp"),  at any
     time after the sixth anniversary of the Original Issue Date, if on the date
     of exercise by UtiliCorp the Closing  Price (as defined in Section  4(b)(i)
     below) of the  Corporation's  Common  Stock is $30.00 or less  (subject  to
     adjustment  for any  stock  split,  combination,  and the  like),  then the
     Preferred  Dividend  will be adjusted to the then "market  coupon rate" (as
     defined  below).  The  "market  coupon  rate"  shall  be the  Corporation's
     after-tax cost of obtaining  financing,  excluding common stock, to replace
     UtiliCorp's  investment  in  the  Corporation,   as  determined  by  mutual
     agreement of the parties; provided, however, that if the parties are unable
     to agree upon the market  coupon  rate within 10 days after the date of the
     sixth  anniversary  of the  Original  Issue Date,

                                       2
<PAGE>

     then  the  parties  shall  mutually  agree  upon  a  nationally  recognized
     investment  banking firm skilled in the business  aspects of the subject to
     determine the market coupon rate, such  determination  shall be made by the
     investment banking firm within a 30 days of being selected.  If the parties
     are unable to agree upon a nationally  recognized  investment  banking firm
     within  30 days  after the date of the sixth  anniversary  of the  Original
     Issue  Date,  then  the  determination  shall  be made by a panel  of three
     nationally  recognized  investment  banking  firms  skilled in the business
     aspects  of the  subject.  Each  of the  Corporation  and the  holder  of a
     majority  of the shares of Series A Preferred  Stock shall  select one such
     firm within five days after the expiration of above-mentioned 30-day period
     (the "Initial Selection Period"), and the third such firm shall be selected
     by the two  investment  banking firms within five days after the expiration
     the Initial  Selection  Period.  Within 15 days after the  selection of the
     third  investment  banking firm,  the initial two firms shall submit to the
     third firm their  proposals of the market coupon rate and, within five days
     after  receipt  thereof,  the third firm shall adopt in its entirety one of
     the proposals and shall not adopt a compromise between the proposals of the
     initial two firms. The market coupon rate determined in accordance with the
     above procedure shall,  retroactive to the date  immediately  following the
     sixth  anniversary  of the  Original  Issue  Date  and  thereafter,  be the
     Preferred Dividend.

     3. Voting Rights.

          (a) General.  Each holder of shares of Series A Preferred  Stock shall
     be  entitled to the number of votes equal to the number of shares of Common
     Stock into which the shares of Series A Preferred Stock held by such holder
     are then  convertible,  at each meeting of  stockholders of the Corporation
     (and written actions of stockholders in lieu of meetings),  with respect to
     any and all matters  presented to the  stockholders  of the Corporation for
     their  action or  consideration.  Except as provided by law or as otherwise
     expressly provided herein,  such holder shall have voting rights and powers
     equal to the voting rights and powers of the Common  Stock,  and holders of
     Series A  Preferred  Stock shall vote  together  with the holders of Common
     Stock as a single  class and be  entitled  to  notice of any  stockholders'
     meeting in accordance with the By-laws of the Corporation. Fractional votes
     shall not, however, be permitted and any fractional voting rights resulting
     from the above formula (after  aggregating  all shares into which shares of
     Series A Preferred  Stock held by each holder could be converted)  shall be
     rounded to the nearest whole number (with one-half being rounded upward).

          (b) Election of Directors.  The Board of Directors of the  Corporation
     shall consist of 10 directors.  The directors of the  Corporation  shall be
     elected as follows:

               (i) A majority  of the  outstanding  shares of Series A Preferred
          Stock and the shares of Common  Stock issued upon  conversion  thereof
          (the "Conversion  Shares") (to the extent permitted by applicable law)
          held by UtiliCorp,  voting  exclusively and as a separate class, shall
          be  entitled  to elect two of the total  number  of  directors  of the
          Corporation,  subject  to the  limitations  set  forth in  subsections
          3(b)(ii), (iv) and (v) below.

               (ii) In the event that the ratio of the total number of shares of
          Common  Stock owned by  UtiliCorp  (on an  as-converted  basis) to the
          total  number of shares of Common  Stock  outstanding,  assuming  full
          conversion  of all  securities  and full  exercise of all  outstanding
          rights,  options and  warrants to acquire  Common  Stock (such  ratio,
          "UtiliCorp's  Fully Diluted  Ownership  Ratio") is equal to or greater
          than  30%,  then a  majority  of the  outstanding  shares  of Series A
          Preferred Stock and the Conversion  Shares (to the extent permitted by
          applicable  law)  held  by  UtiliCorp,  voting  exclusively  and  as a
          separate  class,  shall be entitled to elect three of the total number
          of directors of the Corporation.

                                       3
<PAGE>

               (iii) To the  extent any  nominee of the  holders of the Series A
          Preferred Stock is not an officer of UtiliCorp, the Board of Directors
          of the Corporation shall have the right to approve such nominee,  such
          approval  not to be  unreasonably  withheld.  Only the  holders of the
          Series A  Preferred  Stock and the  Conversion  Shares  (to the extent
          permitted by  applicable  law) shall be entitled to remove from office
          such  directors  nominated  by the  holders of the Series A  Preferred
          Stock and the Conversion Shares (to the extent permitted by applicable
          law) or to fill  any  vacancy  caused  by the  resignation,  death  or
          removal of such directors.

               (iv) In the event that UtiliCorp's  Fully Diluted Ownership Ratio
          (A) is less than 10% or (B) UtiliCorp  sells or otherwise  disposes of
          at least  50%,  but less  than 75%,  of the total  number of shares of
          Common  Stock  owned  by  it  on  the  Original   Issue  Date  (on  an
          as-converted  basis),  then a majority  of the  outstanding  shares of
          Series A  Preferred  Stock and the  Conversion  Shares  (to the extent
          permitted by applicable  law) held by UtiliCorp shall only be entitled
          (voting exclusively and as a separate class) to elect one of the total
          number of directors of the Corporation.

               (v) In the event that (A)  UtiliCorp's  Fully  Diluted  Ownership
          Ratio is less than 5% or (B) UtiliCorp sells or otherwise  disposes of
          75% or more of the total  number of shares of Common Stock owned by it
          (on an as-converted  basis), then a majority of the outstanding shares
          of Series A Preferred  Stock and the Conversion  Shares (to the extent
          permitted by  applicable  law) held by  UtiliCorp  shall have no right
          (voting exclusively and as a separate class) to elect any directors to
          the Board of Directors.

               (vi) The holders of Limited Vote Common Stock, voting together as
          a single class,  shall be entitled to elect one member of the Board of
          Directors, but shall not otherwise be entitled to vote in the election
          of directors of the  Corporation.  Only holders of Limited Vote Common
          Stock shall have the right to remove  from office such  director or to
          fill any vacancy caused by the  resignation,  death or removal of such
          director.

               (vii)  Except as provided in Sections  3(b)(i),  (ii),  (iii) and
          (iv) above,  the  holders of Common  Stock and the holders of Series A
          Preferred Stock,  voting together as a single class, shall be entitled
          to elect all members of the Board of Directors.

          (c)  Veto  Rights.  So long as the  outstanding  shares  of  Series  A
     Preferred Stock  represent 10% or more of the outstanding  shares of Common
     Stock (on an  as-converted  basis),  the  approval  by the vote or  written
     consent  of the  holders  of at least  two-thirds  of the then  outstanding
     shares of Series A Preferred  Stock,  voting  together  as a single  class,
     shall be necessary before the Corporation may:

               (i)  Authorize,  issue or enter into any agreement  providing for
          the issuance  (contingent  or  otherwise)  of (A) any  authorized  but
          unissued  shares of  Series A  Preferred  Stock or any other  class or
          series  of  capital  stock  senior  to or on par  with  the  Series  A
          Preferred  Stock  as to  dividend  rights  or (B)  any  notes  or debt
          securities containing equity features,  including, without limitation,
          any notes or debt  securities  convertible  into or  exchangeable  for
          equity securities, having dividend rights on par with or senior to the
          Series A Preferred Stock;

                                       4
<PAGE>

               (ii) Redeem or purchase or  otherwise  acquire any of its capital
          stock,  now or  hereafter  issued,  of any  class,  except for (A) any
          repurchase of shares of capital stock pursuant to any employee benefit
          plan  adopted by the  Corporation,  (B) any payment or  redemption  of
          certain  convertible  subordinated  notes issued by the Corporation on
          October 5, 1998 to Enron  Capital & Trade  Resources  Corp.  and Joint
          Energy  Development  Investments II Limited  Partnership,  and (C) any
          acquisition of shares of capital stock by the Corporation  pursuant to
          agreements  which permit the Corporation to repurchase such shares (1)
          upon  termination  of services to the  Corporation  entered into on or
          before  the  Original  Issue  Date  or  (2)  in   satisfaction  of  an
          indemnification  obligation  to the  Corporation  upon a breach by the
          holder of Common  Stock of a  representation,  warranty or covenant in
          any agreement for an Acquisition;

               (iii)  Enter  into  a  transaction  or  series  of   transactions
          resulting in the sale, lease,  transfer or other disposition of all or
          substantially  all of the  assets  of the  Corporation  in  which  the
          holders of the Series A Preferred  Stock would  receive  less than the
          Common Stock for each share of Series A Preferred Stock held by them;

               (iv)  Liquidate,  dissolve or wind up the Corporation in any form
          of transaction; or

               (v) Amend  the  Corporation's  Certificate  of  Incorporation  or
          Bylaws  or  the  organizational  documents  of  a  subsidiary  of  the
          Corporation (including the filing of a certificate of designation), in
          each case as  amended,  or file with any  governmental  authority  any
          resolution  of the  Board of  Directors  containing  in each  case any
          provisions which would adversely affect or otherwise impair the voting
          powers,   preferences   or  other   special   rights  or   privileges,
          qualifications,  limitations or restrictions of the Series A Preferred
          Stock (including,  without  limitation,  an amendment or resolution to
          increase  the  number  of  directors  of the  Corporation  to a number
          greater than 10).

     4. Conversion.  The Corporation and holders of the Series A Preferred Stock
shall have, and be subject to, the conversion rights as follows (the "Conversion
Rights"):

          (a) Holder's Right to Convert.  Subject to and in compliance  with the
     provisions  of this Section 4, any shares of Series A Preferred  Stock may,
     at the option of the holder,  be  converted at any time into fully paid and
     nonassessable  shares of Common Stock. The number of shares of Common Stock
     to which a holder  of  Series A  Preferred  Stock  shall be  entitled  upon
     conversion by the holder shall be the product  obtained by multiplying  the
     Series A  Preferred  Stock Rate then in effect  (determined  as provided in
     Section  4(b)(ii))  times the number of shares of Series A Preferred  Stock
     being converted by such holder. (b) Certain Definitions and Determinations.
     As used in Sections 4 and 5, the  following  terms shall have the following
     meanings:

               (i)  "Closing  Price" means on any  particular  date (A) the last
          sale price per share of the Common Stock on such date on the principal
          stock  exchange on which the Common Stock has been listed or, if there
          is no such  price  on such  date,  then the  last  sale  price on such
          exchange on the date nearest  preceding  such date,  (B) if the Common
          Stock is not listed on any stock  exchange,  the final bid price for a
          share of Common Stock in the  over-the-counter

                                       5

          market, as reported by the National  Association of Securities Dealers
          Automated Quotation System ("NASDAQ") at the close of business on such
          date,  or the last sales price if such price is reported and final bid
          prices are not available, (C) if the Common Stock is not quoted on the
          NASDAQ,   the  bid  price   for  a  share  of  Common   Stock  in  the
          over-the-counter  market as reported by the National  Quotation Bureau
          Incorporated (or any similar  organization or agency succeeding to its
          functions  of  reporting  prices),  or (D) if the  Common  Stock is no
          longer publicly  traded,  as determined by an investment  banking firm
          selected in good faith by the Board of Directors  based upon the price
          that  would be paid by a willing  buyer of the  shares at issue,  in a
          sale  process  designed  to maximize  value and  attract a  reasonable
          number of participants to provide a fair  determination of such value,
          provided, that none of the transactions related to the foregoing shall
          include  purchases by any  "affiliate" (as defined in Rule 12b-2 under
          the Securities Act of 1933) of the Corporation.

               (ii) The conversion  rate in effect at any time for conversion of
          the Series A Preferred Stock (the "Preferred Stock Rate") shall be the
          quotient  obtained by dividing  the  Original  Issue Price (as defined
          below) by the  Conversion  Price,  calculated  as  provided in Section
          4(b)(iv).

               (iii) The "Original  Issue Price" of the Series A Preferred Stock
          shall equal the Purchase Price with respect to each share (as adjusted
          for any  stock  dividends,  combinations,  splits  and the  like  with
          respect to such shares).

               (iv)  The  conversion   price  shall  initially  be  $30.00  (the
          "Conversion  Price").  The initial  Conversion Price shall be adjusted
          from time to time in accordance  with the provisions of Section 5. All
          references to the  Conversion  Price herein shall mean the  Conversion
          Price as so adjusted.

          (c)  Automatic  Conversion  Prior to  Liquidation.  In the  event of a
     liquidation   of  the   Corporation,   the   Conversion   Rights  shall  be
     automatically exercised at the close of business on the first full business
     day preceding  the date fixed for the payment of any amounts  distributable
     on liquidation to the holders of Common Stock.

          (d) Fractional  Shares.  No fractional shares of Common Stock shall be
     issued  upon  conversion  of the Series A  Preferred  Stock.  All shares of
     Common Stock (including fractions thereof) issuable upon conversion of more
     than one share of Series A Preferred  Stock by a holder shall be aggregated
     for  purposes of  determining  whether the  conversion  would result in the
     issuance of any fractional share. In lieu of any fractional shares to which
     the holder  would  otherwise be entitled,  the  Corporation  shall pay cash
     equal to such  fractional  share of Common Stock  multiplied by the Closing
     Price of the Common Stock on the business day immediately prior to the date
     on which  conversion  is  deemed  to occur  (as  determined  in  subsection
     4(e)(ii) below).

          (e) Mechanics of Conversion.

               (i) In order for a holder of Series A Preferred  Stock to convert
          shares of Series A Preferred  Stock into shares of Common Stock,  such
          holder shall surrender the certificate or certificates for such shares
          of Series A Preferred  Stock,  at the office of the transfer

                                       6
<PAGE>

          agent for the Series A Preferred Stock (or at the principal  office of
          the Corporation if the Corporation  serves as its own transfer agent),
          together with written notice that such holder elects to convert all or
          any number of the shares of the Series A Preferred  Stock  represented
          by such  certificate  or  certificates.  Such notice  shall state such
          holder's name or the names of the nominees in which such holder wishes
          the  certificate  or  certificates  for  shares of Common  Stock to be
          issued.

               (ii) If required by the Corporation, certificates surrendered for
          conversion shall be endorsed or accompanied by a written instrument or
          instruments of transfer, in form satisfactory to the Corporation, duly
          executed by the  registered  holder or his, her or its  attorney  duly
          authorized in writing.  Provided that the certificates of the Series A
          Preferred  Stock  have  been   surrendered  as  provided  above,   the
          Corporation  shall, as soon as practicable,  issue and deliver at such
          office to such holder of Series A Preferred  Stock,  or to his, her or
          its nominees,  a certificate or certificates  for the number of shares
          of Common Stock to which such holder shall be entitled,  together with
          cash in lieu of any  fraction  of a share.  In the event less than all
          shares   represented  by  such   certificate  are  converted,   a  new
          certificate  shall  be  issued  by the  Corporation  representing  the
          unconverted  shares. Such conversion shall be deemed to have been made
          at the  close  of  business  on the  date  of  such  surrender  of the
          certificates representing the shares of Series A Preferred Stock to be
          converted,  and the person  entitled  to receive  the shares of Common
          Stock issuable upon such conversion  shall be treated for all purposes
          as the record holder of such shares of Common Stock on such date.

          (f) Reservation of Common Stock.  The  Corporation  shall at all times
     when the Series A  Preferred  Stock shall be  outstanding  reserve and keep
     available (free from preemptive  rights) out of its authorized but unissued
     stock, for the purpose of issuing upon conversion of the Series A Preferred
     Stock, such number of shares of Common Stock as shall then be issuable upon
     the conversion of all outstanding  Series A Preferred  Stock. All shares of
     Common Stock so issuable shall,  upon issuance,  be duly and validly issued
     and fully paid and  nonassessable.  Before  taking any action  which  would
     cause an adjustment  reducing the Conversion Price below the then par value
     of the shares of Common  Stock  issuable  upon  conversion  of the Series A
     Preferred  Stock, the Corporation will take any corporate action which may,
     in the opinion of its counsel,  be necessary in order that the  Corporation
     may validly and legally issue fully paid and nonassessable shares of Common
     Stock at such adjusted Conversion Price.

          (g) Notices. Any notice required by the provisions of Sections 2(c), 4
     and 5 shall be in writing and shall be deemed  effectively  given: (i) upon
     personal delivery to the party to be notified,  (ii) when sent by confirmed
     telex or facsimile if sent during normal  business  hours of the recipient;
     if not,  then on the next  business  day,  (iii) five  business  days after
     having been sent by registered or certified mail, return receipt requested,
     postage  prepaid,  or (iv) one business day after deposit with a nationally
     recognized  overnight courier,  specifying next day delivery,  with written
     verification  of receipt.  All notices shall be addressed to each holder of
     record  at the  address  of  such  holder  appearing  on the  books  of the
     Corporation.

          (h) Payment of Taxes.  The Corporation  will pay all taxes (other than
     taxes based upon income or gross receipts) and other  governmental  charges
     that may be  imposed  with  respect to the issue or  delivery  of shares of
     Common  Stock  upon  conversion  of  shares of  Series

                                       7
<PAGE>

     A Preferred Stock,  excluding any tax or other charge imposed in connection
     with any  transfer  involved in the issue and  delivery of shares of Common
     Stock in a name other  than that in which the shares of Series A  Preferred
     Stock so converted were registered.

     5.  Antidilution  Adjustments.  The number and kind of securities  issuable
upon the  conversion  of the  Series A  Preferred  Stock  shall  be  subject  to
adjustment, without duplication, from time to time upon the happening of certain
events occurring on or after the Original Issue Date as follows:

          (a)  Adjustment  for  Stock  Splits  and  Combinations.  In  case  the
     Corporation shall (i) subdivide its outstanding Common Stock into a greater
     number of shares,  (ii) combine its outstanding Common Stock into a smaller
     number  of  shares,  (iii) pay a  dividend  or make a  distribution  on its
     outstanding  Common  Stock in shares of its capital  stock or (iv) issue by
     reclassification  of its  outstanding  Common Stock (whether  pursuant to a
     merger or  consolidation or otherwise) any other shares of capital stock of
     the  Corporation,  the Series A Preferred Stock  surrendered for conversion
     after the record date fixed by the Board of Directors for such subdivision,
     combination,  dividend,  distribution or reclassification shall be entitled
     to receive the aggregate  number and kind of shares of capital stock of the
     Corporation  which,  if this  Series A Preferred  Stock had been  converted
     immediately  prior to such  record  date at the  Conversion  Price  then in
     effect,  such holder would have been  entitled to receive by virtue of such
     subdivision,  combination, dividend, distribution or reclassification;  and
     the  Conversion  Price  shall be deemed to have been  adjusted  after  such
     record  date to apply to such  aggregate  number and kind of  shares.  Such
     adjustment  shall be made  successively  whenever any of the events  listed
     above shall occur.

          (b) Adjustment for Common Stock Dividends and  Distributions.  In case
     the Corporation shall pay a dividend or make a distribution on any class of
     capital stock of the Corporation in shares of Common Stock,  the Conversion
     Price in effect  immediately prior to the record date for the determination
     of stockholders  entitled to receive such dividend or distribution shall be
     reduced by multiplying such Conversion Price by a fraction of which (i) the
     numerator shall be the number of shares of Common Stock  outstanding at the
     close of business on the day immediately prior to such record date and (ii)
     the  denominator  shall be the sum of such  number of shares  and the total
     number of shares issued in such dividend or other distribution.

          (c)  Adjustment for Rights to Acquire Common Stock Below Market Price.
     Subject to Section 5(m) below, in case the  Corporation  shall issue to all
     holders of Common Stock rights or warrants  entitling them to subscribe for
     or purchase  Common Stock at a price per share less than the current market
     price per  share (as  determined  pursuant  to  Section  5(h)  below),  the
     Conversion Price in effect from and after the record date therefor shall be
     reduced so that it shall  equal the price  determined  by  multiplying  the
     Conversion  Price in  effect  immediately  prior to such  record  date by a
     fraction,  of which  (i) the  numerator  shall be the  number  of shares of
     Common Stock  outstanding  on such record date plus the number of shares of
     Common  Stock which the  aggregate  offering  price of the total  number of
     shares of Common  Stock so  offered  for  subscription  or  purchase  would
     purchase at such current market price and (ii) the denominator shall be the
     number of shares of Common Stock  outstanding  on such record date plus the
     number of additional  shares of Common Stock so offered for subscription or
     purchase.  For the purpose of this Section 5(c),  the issuance of rights or
     warrants to subscribe for or purchase  securities

                                       8
<PAGE>

     convertible  into Common Stock shall be deemed to be the issuance of rights
     or warrants to purchase  the Common  Stock into which such  securities  are
     convertible (without regard to any antidilution provision contained therein
     for a subsequent  adjustment of such number) at an aggregate offering price
     equal to the aggregate  offering price of such  securities plus the minimum
     aggregate amount (if any) payable upon (or in connection with) the exercise
     of  such  securities  for  Common  Stock.  Such  adjustment  shall  be made
     successively  whenever such a record date is fixed.  In case such rights or
     warrants  are not  issued  after  such a record  date has been  fixed,  the
     Conversion  Price shall be readjusted to the  Conversion  Price which would
     have been in effect if such record date had not been fixed.

          (d)  Adjustment  for  Distribution  of Debt  or  Assets.  In case  the
     Corporation  shall  distribute  to all  holders  of Common  Stock  (whether
     pursuant  to a merger  or  consolidation  or  otherwise)  evidences  of its
     indebtedness  or  assets   (excluding   shares  of  capital  stock  of  the
     Corporation  and cash  dividends  out of retained  earnings),  or rights to
     subscribe  for Common  Stock at a price less than the current  market price
     per share (excluding those referred to in Section 5(c) above), then in each
     such case the  Conversion  Price in effect  from and after the record  date
     therefor  shall be adjusted so that it shall equal the price  determined by
     multiplying the Conversion Price in effect immediately prior to such record
     date by a fraction,  of which (i) the numerator shall be the current market
     price per share  (determined  as  provided  in Section  5(h)  below) of the
     Common Stock on such record date less the fair market value (as  determined
     by the Board of  Directors,  whose  determination  in good  faith  shall be
     conclusive)  of the portion of the evidences of  indebtedness  or assets so
     distributed  or of such  rights  to  subscribe  applicable  to one share of
     Common Stock and (ii) the  denominator  shall be such current  market price
     per share of  Common  Stock.  Such  adjustment  shall be made  successively
     whenever any such a record date is fixed. In case such  distribution is not
     made after such a record date has been fixed, the Conversion Price shall be
     readjusted to the Conversion  Price which would have been in effect if such
     record date had not been fixed.

          (e) Adjustment for Sales of Common Stock Below Market Price (But Above
     Conversion  Price). If the Corporation shall issue any additional shares of
     Common Stock  (other than as provided in Sections  5(a) through 5(d) above)
     at a price per share less than the current market price per share of Common
     Stock but above the  Conversion  Price in respect of the Series A Preferred
     Stock,  then the Conversion Price shall be adjusted to the price determined
     by  multiplying  the  Conversion  Price  by a  fraction  of  which  (i) the
     numerator  shall be (A) the sum of (1) the number of shares of Common Stock
     outstanding  immediately prior to the issuance of such additional shares of
     Common  Stock   multiplied  by  the  current   market  price  and  (2)  the
     consideration, if any, received and deemed received by the Corporation upon
     the issuance of such  additional  shares of Common Stock (B) divided by the
     total number of shares of Common Stock  outstanding  immediately  after the
     issuance  of  such  additional   shares  of  Common  Stock,  and  (ii)  the
     denominator shall be the current market price.

          (f) Adjustment for Sales of Common Stock Below  Conversion  Price.  If
     the  Corporation  shall issue any additional  shares of Common Stock (other
     than as provided in Sections  5(a) through 5(e) above) at a price per share
     less than the Conversion Price, then the Conversion Price shall be adjusted
     to the  price  determined  by  multiplying  the  Conversion  Price  times a
     fraction of which (i) the numerator  shall be (A) the sum of (1) the number
     of shares of Common Stock outstanding  immediately prior to the issuance of
     such additional  shares of

                                       9
<PAGE>

     Common Stock multiplied by the Conversion Price and (2) the  consideration,
     if any,  received and deemed received by the Corporation  upon the issuance
     of such  additional  shares of Common Stock (B) divided by the total number
     of shares of Common  Stock  outstanding  immediately  after the issuance of
     such additional  shares of Common Stock, and (ii) the denominator  shall be
     the Conversion Price.

          (g) Certain Determinations.

               (i) In case the Corporation  shall issue any security or evidence
          of indebtedness  which is convertible  into or exchangeable for Common
          Stock ("Convertible Security"), or any warrant, option or other rights
          to subscribe for or purchase Common Stock or any Convertible  Security
          (together with Convertible Securities,  "Common Stock Equivalent"), or
          if,  after any such  issuance,  the  price  per  share for which  such
          additional  shares  of  Common  Stock may be  issuable  thereunder  is
          amended,  then, for purposes of Sections 5(e) and (f), (A) the maximum
          number of additional  shares of Common Stock issuable  pursuant to all
          such Common  Stock  Equivalents  (without  regard to any  antidilution
          provision  contained  therein  for a  subsequent  adjustment  of  such
          number)  shall be deemed to have been  issued as of the earlier of (1)
          the date on which the Corporation shall enter into a firm contract for
          the issuance of such Common Stock Equivalent or (2) the date of actual
          issuance  of such  Common  Stock  Equivalent,  and  (B) the  aggregate
          consideration  for such maximum number of additional  shares of Common
          Stock shall be deemed to be the  minimum  consideration  received  and
          receivable  by the  Corporation  for the  issuance of such  additional
          shares of Common Stock  pursuant to such Common Stock  Equivalent.  No
          adjustment of the Conversion  Price shall be made under this paragraph
          upon the  issuance or deemed  issuance  of any shares of Common  Stock
          pursuant to the exercise of any  conversion or exchange  rights of any
          Convertible  Security  or pursuant  to the  exercise of any  warrants,
          options,  or other subscription or purchase rights, if any adjustments
          shall previously have been made in the Conversion Price then in effect
          upon the issuance of such Convertible Securities, warrants, options or
          other rights pursuant hereto.

               (ii) The  following  provisions  shall be applicable to making of
          adjustments in the Conversion Price hereinbefore  provided in Sections
          5(c), (d), (e) and (f):

                    (A) The  consideration  received by the Corporation shall be
               deemed to be the following:

                         (1) (x) To the  extent  that any  additional  shares of
                    Common Stock or any Common Stock Equivalents shall be issued
                    for cash  consideration,  the consideration  received by the
                    Corporation  therefor,  or, (y) if such additional shares of
                    Common Stock or Common Stock  Equivalents are offered by the
                    Corporation for  subscription,  the subscription  price, or,
                    (z) if such  additional  shares  of  Common  Stock or Common
                    Stock  Equivalents  are sold to  underwriters or dealers for
                    public offering without a subscription offering, the initial
                    public  offering  price,  in any  such  case  excluding  any
                    amounts paid or receivable  for accrued  interest or accrued
                    dividends  and  without   deduction  of  any   compensation,
                    discounts,  commissions  or expenses paid or incurred by the
                    Corporation for and in the  underwriting of, or otherwise in
                    connection with, the issue thereof;

                                       10
<PAGE>

                         (2) To the  extent  that such  issuance  shall be for a
                    consideration  other  than  cash,  then,  except  as  herein
                    otherwise expressly provided,  the fair market value of such
                    consideration  at the time of such issuance as determined in
                    good faith by the Board of  Directors.  In any case in which
                    the consideration to be received or paid shall be other than
                    cash, the Board of Directors of the Corporation shall notify
                    promptly each holder of the Series A Preferred  Stock of its
                    determination   of   the   fair   market   value   of   such
                    consideration;

                         (3) The  consideration  for any  additional  shares  of
                    Common   Stock   issuable   pursuant  to  any  Common  Stock
                    Equivalents  shall  be  the  consideration  received  by the
                    Corporation for issuing such Common Stock Equivalents,  plus
                    the additional consideration payable to the Corporation upon
                    the  exercise,  conversion  or exchange of such Common Stock
                    Equivalents; and

                         (4)  In  case  of  the  issuance  at  any  time  of any
                    additional   shares   of  Common   Stock  or  Common   Stock
                    Equivalents in payment or  satisfaction of any dividend upon
                    any class of stock other than Common Stock,  the Corporation
                    shall be deemed to have received for such additional  shares
                    of Common Stock or Common Stock  Equivalents a consideration
                    equal to the amount of such dividend so paid or satisfied.

          (B) Upon the expiration of the right to convert,  exchange or exercise
     any Common Stock Equivalent the issuance of which effected an adjustment in
     the Conversion  Price, if any such Common Stock  Equivalent  shall not have
     been converted,  exercised or exchanged, (1) the number of shares of Common
     Stock deemed to be issued and  outstanding  by reason of the fact that they
     were  issuable  upon  conversion,  exchange  or exercise of any such Common
     Stock  Equivalent  shall no longer be computed as set forth above,  (2) the
     Conversion  Price shall forthwith be readjusted and thereafter be the price
     which it would  have been (but  reflecting  any  other  adjustments  in the
     Conversion  Price made  pursuant to the  provisions of this Section 5 after
     the issuance of such Common Stock  Equivalent)  had the  adjustment  of the
     Conversion  Price  made  upon the  issuance  or sale of such  Common  Stock
     Equivalent  been made on the basis of the  issuance  only of the  number of
     additional shares of Common Stock actually issued upon exercise, conversion
     or exchange of such Common Stock  Equivalent,  and (3)  thereupon  only the
     number of  additional  shares of Common  Stock  actually so issued shall be
     deemed to have been issued and only the consideration  actually received by
     the  Corporation  (computed as in clause (A) above) shall be deemed to have
     been received by the Corporation.

               (iii)  The  number  of  shares  of  Common   Stock  at  any  time
          outstanding  shall not include  any shares  thereof  then  directly or
          indirectly  owned or held by or for the account of the  Corporation or
          its subsidiaries.

               (iv)  No  adjustments  of the  Conversion  Price  shall  be  made
          pursuant to Sections 5(c), (e), and (f) upon the issuance of shares of
          Common  Stock that are issued  pursuant  to (x) any  employee  benefit
          plan,  program or policy  approved  by the Board of  Directors  of the
          Corporation, including thrift plans, stock purchase plans, stock bonus
          plans,  stock options plans,  employee stock  ownership plans or other
          incentive  or  profit  sharing   arrangements,   for  the  benefit  of
          employees,   officers  or   directors  of  the   Corporation   or  its
          "affiliates"  (as defined in Rule 12b-2

                                       11
<PAGE>

     under the Securities  Exchange Act of 1934, as amended) or (y) Acquisitions
     made by the Corporation.

          (h) Current  Market Price.  For the purpose of any  computation  under
     Sections 5(c), (d) and (e) above,  the current market price shall be deemed
     to be the following:

               (i) With respect to a bonafide underwritten public offering,  the
          offering price agreed to by the underwriter;

               (ii) With respect to binding  agreements  made by the Corporation
          to issue shares of Common Stock for a price that is (A)  determined as
          of  the  date  of the  agreement  with  reference  to a  market  price
          contemporaneous with the date of the binding agreement and (B) without
          full adjustment to the Closing Price on the day of issuance, the price
          as determined by such binding agreement; or

               (iii) With  respect to all other  situations,  the average of the
          daily Closing  Prices for 30  consecutive  trading days  commencing 45
          trading days before the date in question.

          (i)  Deferral of Share  Issuance.  In any case in which this Section 5
     shall require that an adjustment as a result of any event becomes effective
     from and after a record date, the Corporation my elect to defer until after
     the  occurrence  of such  event  (i)  issuing  to the  holder  of  Series A
     Preferred  Stock converted after such record date and before the occurrence
     of such event the  additional  shares of Common  Stock  issuable  upon such
     conversion  over  and  above  the  shares  issuable  on  the  basis  of the
     Conversion Price in effect  immediately prior to adjustment and (ii) paying
     to such holder any amount in cash in lieu of a  fractional  share of Common
     Stock pursuant to Section 4(d) above. In lieu of the shares the issuance of
     which is deferred  pursuant to this Section  5(i),  the  Corporation  shall
     issue or cause a  transfer  agent to issue due  bills or other  appropriate
     evidence of the right to receive such shares  promptly after the occurrence
     of such event.

          (j) De Minimis  Adjustments.  Any adjustment in the  Conversion  Price
     otherwise  required by this Section 5 to be made may be postponed until the
     date  of  the  next  adjustment  otherwise  required  to be  made  if  such
     adjustment (together with any other adjustments  postponed pursuant to this
     Section 5 and not  theretofore  made)  would not  require  an  increase  or
     decrease  of more than 1% in such price,  but in the case of an  adjustment
     required as a result of a dividend or  distribution on any class of capital
     stock of the Corporation in shares of Common Stock, such adjustment must be
     made no later than the  earlier of (a) 3 years  after the date of the stock
     dividend or  distribution  or (b) the date as of which the aggregate  stock
     dividends or distributions for which adjustment of the Conversion Price has
     not  previously  been made total at least 3% of the issued and  outstanding
     capital stock of the Corporation with respect to which such stock dividends
     or distributions  were made. All calculations under this Section 5 shall be
     made to the nearest cent or to the nearest  1/100th of a share, as the case
     may be.

          (k) Applicability to Other Shares. In case at any time, as a result of
     an adjustment made pursuant to Section 5(a)(iii) or (iv) above, the holders
     of the Series A Preferred Stock thereafter surrendered for conversion shall
     become  entitled to receive any shares of capital stock of the  Corporation
     other than  Common  Stock,  the  number  and kind of such  other  shares so


                                       12
<PAGE>

     receivable upon conversion of Series A Preferred Stock shall  thereafter be
     subject to adjustment  from time to time in a manner and on terms as nearly
     equivalent  as  practicable  to the  provisions  with respect to the Common
     Stock  contained  in clauses (a) to (g),  inclusive,  above,  and the other
     provisions  of this  Section 5 with respect to the Common Stock shall apply
     on like terms to any such other shares.

          (l)  Board  Determinations.  The  Board of  Directors  may  make  such
     reductions in the Conversion  Price,  in addition to those required by this
     Section 5, as shall be determined by the Board of Directors to be advisable
     in order to avoid  taxation so far as  practicable of any dividend of stock
     or stock  rights  or any  event  treated  as such for  federal  income  tax
     purposes to the recipients.  The Board of Directors shall have the power to
     resolve any  ambiguity  or correct any error in this Section 5, and (absent
     manifest  error by the Board of Directors)  its action in so doing shall be
     final and conclusive.

          (m) Rights  Plan.  With  respect to any  stockholder  rights plan (the
     "Rights  Plan")  pursuant to which  "rights" would be issued or issuable to
     stockholders  of the  Corporation,  no  adjustment  shall  be  made  to the
     Conversion  Price as a result  of such  Rights  Plan in the  event  that an
     appropriate  amount of "rights"  are either (i)  reserved  for  issuance in
     connection with the issuance of Conversion  Shares to the holders of Series
     A Preferred Stock or (ii) are issued to holders of Series A Preferred Stock
     on an as converted  basis.  Unless rights are so issued  pursuant to clause
     (ii) of this Section 5(m), if and when the rights  become  exercisable,  an
     appropriate adjustment to the Conversion Price in accordance with the terms
     of the Rights Plan shall be made pursuant to this Section 5.

          (n)  Notices  of  Adjustment.   In  each  case  of  an  adjustment  or
     readjustment  of the  Conversion  Price for the  number of shares of Common
     Stock or other  securities  issuable upon  conversion of shares of Series A
     Preferred  Stock,  if the  Series A  Preferred  Stock  is then  convertible
     pursuant to Section 4, the Corporation,  at its expense, shall compute such
     adjustment or  readjustment  in accordance  with the provisions  hereof and
     prepare a certificate  showing such adjustment or  readjustment,  and shall
     deliver such  certificate to each  registered  holder of Series A Preferred
     Stock.  The certificate  shall set forth such  adjustment or  readjustment,
     showing in detail the facts upon which such  adjustment or  readjustment is
     based,  including (without limitation) a statement of (i) the consideration
     received  or deemed to be received by the  Corporation  for any  additional
     securities  issued or sold or deemed to have been issued or sold,  (ii) the
     Conversion  Price at the time in  effect,  (iii) the  number of  additional
     securities and (iv) the type and amount, if any, of other property which at
     the time would be received upon conversion of the Series A Preferred Stock.

          (o) Notices of Record Date.  Upon (i) any taking by the Corporation of
     a record of the  holders  of any class of  securities  for the  purpose  of
     determining the holders thereof who are entitled to receive any dividend or
     other distribution or (ii) other capital reorganization of the Corporation,
     any  reclassification  or  recapitalization  of the  capital  stock  of the
     Corporation,  any merger or  consolidation  of the Corporation with or into
     any  other  corporation,  or  any  voluntary  or  involuntary  dissolution,
     liquidation or winding up of the Corporation, the Corporation shall send to
     each holder of the Series A Preferred Stock at least 20 calendar days prior
     to the record date  specified  therein a notice  specifying (A) the date on
     which any such  record is to be taken for the  purpose of such  dividend or
     distribution  and a description of such

                                       13
<PAGE>

     dividend or  distribution,  (B) the date on which any such  reorganization,
     reclassification, transfer, consolidation, merger, dissolution, liquidation
     or winding up is expected to become  effective,  and (C) the date,  if any,
     that is to be fixed as to when the  holders  of record of Common  Stock (or
     other  securities)  shall be entitled to  exchange  their  shares of Common
     Stock (or other  securities)  for securities or other property  deliverable
     upon  such  reorganization,   reclassification,   transfer,  consolidation,
     merger, dissolution, liquidation or winding up.
