                             LLC PURCHASE AGREEMENT

          This LLC Purchase Agreement, dated as of September 14, 2002 (this
"Agreement"), is entered into by and among AquaSource, Inc., a Delaware
corporation (the "Seller"), and DQE, Inc., a Pennsylvania corporation ("DQE"),
on the one hand, and Southwest Water Company, a Delaware corporation (the
"Buyer"), on the other hand.

          WHEREAS, the Seller owns all of the issued and outstanding membership
interest (the "Membership Interests") of AquaSource Services I, LLC, a Delaware
limited liability company ("Services I");

          WHEREAS, Services I and its Subsidiaries (as defined in Section 3.2),
AquaSource Services II, LLC, a Delaware limited liability company ("Services
II"), and AquaSource Services, LP, a Texas limited partnership ("Services, LP"),
together with the Company Subsidiaries (as defined in Section 3.2), are
collectively referred to in this Agreement as the "Company"; and

          WHEREAS, each of the Boards of Directors of the Buyer and the Seller
and DQE, as applicable, has approved, and deems it advisable and in the best
interests of its respective shareholders to consummate, the acquisition of the
Company by the Buyer, which acquisition is to be effected by the purchase of all
of the Membership Interests by the Buyer upon the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound hereby, agree as follows:

                                    ARTICLE I
                    PURCHASE AND SALE OF MEMBERSHIP INTERESTS

          Section 1.1 Sale and Transfer of Membership Interests. Subject to the
terms and conditions of this Agreement, on the Closing Date (as defined in
Section 2.1), the Seller agrees to sell, convey, assign, transfer and deliver to
the Buyer, and the Buyer agrees to purchase and accept from the Seller, all of
the Seller's rights, title and interest in and to the Membership Interests.

          Section 1.2 The Purchase Price. Subject to the terms and conditions of
this Agreement, in consideration of the aforesaid sale, conveyance, assignment,
transfer and delivery to the Buyer of the Membership Interests, the Buyer shall
pay to the Seller the following amounts (together, the "Purchase Price")
pursuant to the provisions of this Section 1.2:

               (a) $7,500,000 in cash at Closing;

               (b) An amount of cash equal to ninety percent (90%) of the Net
Accounts Receivable at Closing. For purposes of this Agreement, "Net Accounts
Receivable" shall mean the aggregate amount of the Company's outstanding
accounts receivable as of the Closing Date, calculated in accordance with
existing practices and procedures used by the

                                        1

<PAGE>

Company, minus the amount of any allowance for doubtful accounts attributable to
such accounts receivable then included on the books of the Company, provided
that the amount of any such allowance for doubtful accounts shall be calculated
by taking the aggregate amount of all accounts receivable then included on the
books of the Company that have aged more than 120 days, multiplying such
aggregate amount by a factor of 0.08, and then adding to the resulting product
the amount of $450,000;

               (c) An amount of cash equal to fifty percent (50%) of the
Unbilled Active Work Order Revenue at Closing. For purposes of this Agreement,
"Unbilled Active Work Order Revenue" shall mean the aggregate amount of the
Company's unbilled revenue attributable to active work orders of the Company for
work or services not then fully completed and shall be calculated by determining
the number of such active work orders in accordance with existing practices and
procedures used by the Company and multiplying such number by $288.29; and

               (d) An amount of cash equal to one hundred percent (100%) of the
Other Unbilled Revenue at Closing. For purposes of this Agreement, "Other
Unbilled Revenue" shall mean the aggregate amount of the Company's unbilled
revenue attributable to any source other than active work orders of the Company
for work or services not then fully completed, including, but not limited to,
revenue attributable to base fees, retainer fees or similar fees and revenue
attributable to work or services that have been fully completed, and shall be
calculated in accordance with existing practices and procedures used by the
Company.

          Section 1.3 Certain Liabilities, Accounts Receivable and Accounts
Payable.

               (a) Consistent with the June 30, 2002 Balance Sheet (as defined
in Section 3.5), but subject to agreements in Section 1.3(b) below regarding
Pre-Closing APs (as defined in Section 1.3(b)), the Seller agrees that at
Closing the Company will have no accounts payable, no cash and no intercompany
receivables or payables. However, the Buyer agrees that it will assume vacation
accruals, but expressly not accrued payroll for any employees, through the
Closing Date for employees who accept the Company's Qualifying Offer made
pursuant to Section 6.6(a) below. Additionally, the Keystone, South Dakota,
industrial revenue bond obligation will remain an obligation of the Company
after the Closing.

               (b) The Seller or DQE will pay, in the ordinary course and
consistent with past practice, all of the Company's accounts payable for
obligations incurred prior to Closing ("Pre-Closing APs") that are received in
the ordinary course of business prior to the Closing. The Buyer will forward to
the Seller all Pre-Closing APs received by the Company in the ordinary course of
business during the thirty (30) day period commencing on the Closing Date, and
Seller will pay such Pre-Closing APs. All Pre-Closing APs received by the
Company after such thirty (30) day period will be paid by the Buyer, but all
amounts so paid will each be a Buyer Indemnifiable Loss (as defined in Section
9.1) in accordance with the terms of Article IX.

          Section 1.4 Ongoing Revenues Statement. On the Closing Date, the
earned revenues of the Company for the ninety (90) day period prior to the
Closing Date for ongoing customer relations and customer contracts (the "90 Day
Ongoing Revenues") must total at least $3,750,000. At the same time that the
Seller prepares and delivers to the Buyer the Final Closing

                                        2

<PAGE>

Statement (as defined below), the Seller will prepare and deliver to the Buyer a
statement (the "Revenue Statement") showing the calculation and amount of the 90
Day Ongoing Revenues. Such calculation will be performed according to the
methods and procedures historically used by the Company for calculating earned
revenues. Together with the Revenue Statement, the Seller will provide to the
Buyer copies of the worksheets and other documentation showing in reasonable
detail how the 90 Day Ongoing Revenues were calculated. In the event that the 90
Day Ongoing Revenues are less than $3,750,000, then together with delivery of
the Revenue Statement, the Seller will make a payment to Buyer in the amount of
$.45 for each $1 by which the 90 Day Ongoing Revenues are less than $3,750,000.

          Section 1.5 Closing Statements and Payments.

               (a) At least ten (10) calendar days prior to the Closing Date,
the Seller shall prepare and deliver to the Buyer in good faith its estimate of
the Purchase Price as calculated pursuant to Section 1.2 (the "Estimated Closing
Statement"). For the avoidance of doubt, at the Closing, the Buyer shall pay to
the Seller the Purchase Price as reflected on the Estimated Closing Statement.

               (b) Within fifteen (15) calendar days following the Closing Date,
the Seller shall prepare and deliver to the Buyer in good faith a Final Closing
Statement setting forth the Purchase Price as calculated pursuant to Section 1.2
(the "Final Closing Statement"). Within fifteen (15) calendar days following the
Buyer's receipt of the Final Closing Statement and the Revenue Statement, the
Buyer may object in good faith to the Final Closing Statement and/or the Revenue
Statement in writing. In the event of any such objection, the Buyer and the
Seller shall attempt to resolve their differences by negotiation. If such
parties are unable to do so within thirty (30) calendar days following the
Seller's receipt of the Buyer's objection, the Seller and the Buyer shall
appoint a nationally recognized accounting firm mutually acceptable to each of
the Seller and the Buyer, which shall, at the Seller's and the Buyer's joint
expense, review the Final Closing Statement and the Revenue Statement, as
applicable, and determine the Purchase Price and the 90 Day Ongoing Revenues, as
applicable, within thirty (30) calendar days of such appointment. The Seller and
the Buyer shall be entitled to make a written submission to such accounting firm
setting forth their respective positions and proposed Purchase Price and amount
of 90 Day Ongoing Revenues, as applicable. In addition, the Seller and the Buyer
agree to cooperate with such accounting firm and provide it with such
information as it reasonably requests to enable it to make such determination.
The finding of such accounting firm shall be binding on the parties hereto but
is expressly limited to (i) a determination of the Purchase Price that neither
exceeds the Seller's proposed Purchase Price nor is less than the Buyer's
proposed Purchase Price, and (ii) a determination of the amount of 90 Day
Ongoing Revenues that neither exceeds the Seller's proposed amount of such
revenues nor is less than the Buyer's proposed amount of such revenues, as
applicable. Upon determination by agreement of the Seller and the Buyer or by
binding determination of said accounting firm of the Purchase Price or the
amount of the 90 Day Ongoing Revenues, as applicable, (i) if the Purchase Price
or the amount of the 90 Day Ongoing Revenues, as applicable, that is finally
agreed upon or determined exceeds the Purchase Price or the amount of the 90 Day
Ongoing Revenues, as applicable, that was reflected on the Estimated Closing
Statement or the Revenue Statement, as applicable (such excess amount, the
"Deficiency"), the Buyer shall pay to the Seller an amount of cash equal to the
Deficiency, or (ii) if the Purchase Price or the amount of the 90 Day Ongoing
Revenues, as

                                        3

<PAGE>

applicable, that was reflected on the Estimated Closing Statement or the Revenue
Statement, as applicable, exceeds the Purchase Price that is finally agreed upon
or determined (such excess amount, the "Excess"), the Seller shall pay to the
Buyer an amount of cash equal to the Excess. Any amount of cash in respect of
any Deficiency or Excess owed hereunder shall be paid to the party owed the same
by the party owing the same by wire transfer in immediately available funds to
an account designed by the party owed the same no later than five (5) business
days following the determination by agreement of the Seller and the Buyer or by
binding determination of said accounting firm of the Purchase Price.

                                   ARTICLE II
                                   THE CLOSING

          Section 2.1 Closing. The consummation of the sale and transfer of the
Membership Interests by the Seller to the Buyer (the "Closing") shall take place
at the Washington, D.C. office of Skadden, Arps, Slate, Meagher & Flom LLP at
10:00 a.m., local time, on the fifth business day immediately following the date
on which the last of the conditions set forth in Article VII hereof is fulfilled
or waived, or at such other time, date and place as the Seller and the Buyer
shall mutually agree (the "Closing Date").

          Section 2.2 Closing Transactions. At the Closing:

               (a) The Seller shall deliver to the Buyer (i) free and clear of
any liens, claims, security interests and other encumbrances of any nature
whatsoever (collectively, "Encumbrances"), except for those Encumbrances arising
pursuant to restrictions on the transfer of securities imposed under the
Securities Act of 1933, as amended (the "Securities Act") or any applicable
state securities laws and those Encumbrances created by this Agreement or the
Buyer (collectively, "Permitted Encumbrances"), certificates representing the
Membership Interests, each such certificate to be duly and validly endorsed in
favor of the Buyer or accompanied by a separate instrument of assignment
sufficient to vest in the Buyer good title to the Membership Interests and (ii)
such other documents as are required to be delivered by the Seller to the Buyer
pursuant hereto; and

               (b) The Buyer shall deliver to the Seller (i) the portion of the
Purchase Price to be paid at the Closing, by wire transfer in immediately
available funds to an account designated by the Seller prior to the Closing, and
(ii) such other documents as are required to be delivered by the Buyer to the
Seller pursuant hereto.

                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

          The Seller and, only where specifically noted, DQE, represent and
warrant to the Buyer as follows, provided, however, that notwithstanding any
other provision of this Agreement to the contrary, the Seller and DQE make no
representations or warranties with respect to any of the Excluded Assets (as
defined in Section 5.3) and all representations and warranties of the Seller
and, as applicable, DQE, contained herein expressly exclude such Excluded Assets
and shall not be read or deemed to be a representation or warranty regarding any
Excluded Asset,

                                        4

consequently, as used in this Article III, the terms "Company", "Company
Subsidiary" and "Company Subsidiaries" shall not be read or deemed to include

as it is now being conducted and is duly qualified to do business in each
jurisdiction in which the nature of its business or the ownership or leasing of
its assets and properties makes such qualification necessary other than in such
jurisdictions where the failure to be in good standing or be so qualified is not
reasonably likely, individually or in the aggregate, to have a Buyer Material
Adverse Effect (as defined

                                       14

<PAGE>

below). As used in this Agreement, the term "Buyer Material Adverse Effect"

contemplated hereby. This Agreement has been duly executed and delivered by the
Buyer and, assuming the due authorization, execution and delivery hereof by the
Seller and DQE, constitutes the valid and binding obligation of the Buyer

Material Adverse Effect.

the Buyer Disclosure Schedule (the "Buyer Required Statutory Approvals"), no
declaration, filing or registration with, or notice to or authorization, consent
or approval of, any Governmental Authority is necessary for the execution and
delivery of this Agreement by the Buyer or the consummation by the Buyer of the
transactions contemplated hereby, except those which the failure to obtain is
not reasonably likely to have a Buyer Material Adverse Effect (it being
understood that references in this Agreement to "obtaining" such Buyer Required
Statutory

                                       15

of the Buyer Disclosure Schedule or as disclosed in the Buyer SEC Reports filed
prior to the date hereof, the Buyer and the Buyer Subsidiaries have all permits,
licenses, franchises and other governmental authorizations, consents and
approvals necessary to conduct their businesses as presently conducted except
those that the absence of which is not reasonably likely to have a Buyer
Material Adverse Effect. Except as set forth in Section 4.2(d)(iii) of the Buyer
Disclosure Schedule, neither the Buyer nor any Buyer Subsidiary is in breach or
violation of or in default in the performance or observance of any term or
provision of, and no event has occurred which, with lapse of time or action by a

lease, bond, license, approval or other instrument to which they are a party or

proceedings by any court, governmental department, commission, agency,

to the extent the Buyer deemed appropriate, by the officers, directors,
employees, accountants, counsel, investment bankers, financial advisors and
other representatives (collectively, "Representatives") of Buyer. The Buyer
acknowledges that it and its Representatives have been provided adequate access
to the personnel, properties, premises and records of the Company for such

laws or otherwise) based upon any information provided or made available, or
statements made (including in materials furnished in the Seller's data room, in
presentations by the Seller's management, on site visits or otherwise) to the
Buyer or its directors, officers, employees, affiliates, controlling Persons,
advisors, agents or Representatives (or any omissions therefrom), including in
respect of the specific representations and warranties of the Seller and, as
applicable, DQE set forth in Article III of this Agreement.

          For the avoidance of doubt, the foregoing limitations, representations

condition or if such representation or warranty were not qualified by the term
Buyer Material Adverse Effect. The Buyer will promptly notify the Seller of the
occurrence of any breach of any covenant of the Buyer in this Agreement, or of

LP's and the Company Subsidiaries' right, title and interest in and to all of
those assets set forth on Section 5.3 of the Seller Disclosure Schedule

any

                                       20

the representations and warranties of the Seller set forth in the last sentence
of Section 3.3 or the Seller's and DQE's indemnification obligations under
Article IX, recognizing that such indemnification obligations are always subject
to the limitations and restrictions contained in Articles IX and X. For
avoidance of doubt, liabilities and obligations of DQE, the Seller, any
Subsidiary of the Seller or the Company relating to the Integrated Assets which
arise prior to the Closing shall be Buyer Indemnifiable Losses and subject to
the Seller's and DQE's indemnification obligations under Article IX, and
liabilities and obligations of DQE, the Seller, any Subsidiary of the Seller or
the Company relating to the Integrated Assets which arise after the Closing and

state regulatory agency or commission and (ii) access to all information
concerning the Integrated Assets and the Company and its respective directors
and officers and such other matters as may be reasonably requested by the Buyer
or its Representatives in connection with any filings, applications or approvals
required or contemplated by this Agreement or for any other reason related to
the transactions contemplated by this Agreement; provided, however, that (i) any
such access shall be granted only in such a manner as not to interfere
unreasonably with the Seller's business operations in respect of the Company or
otherwise, (ii) upon being granted such access, the Buyer shall not interfere
with the Seller's business operations in respect of the Company or otherwise,
(iii) in granting any such access the Seller, Services I, Services II, Services,
LP and the Company Subsidiaries shall not be required to take any action that
would constitute a waiver of any legal privilege, including the attorney-client
privilege, the work product privilege and the self critical investigation
privilege, (iv) in granting any such access, the Seller, Services I, Services
II, Services, LP and the Company Subsidiaries shall not be required to provide
the Buyer with access to any information which the Seller, Services I, Services
II, Services, LP or any Company Subsidiary is under a legal or contractual
obligation to withhold from disclosure, and (v) in granting such access, the
Seller, Services I, Services II, Services, LP and the Company Subsidiaries shall
not be required to provide the Buyer with access to any information that relates
exclusively to the Excluded Assets, provided that, in all cases, the Seller
shall be entitled to redact information relating to the Excluded Assets from any
information to which the Buyer is granted access. The Buyer shall, and shall
cause its Subsidiaries and Representatives to, hold in strict confidence all
documents and information concerning the Seller or the Company furnished or made
available to it in connection with the transactions contemplated by this
Agreement in accordance with the Confidentiality Agreement, dated January 5,
2001, entered into by and among the Seller, DQE and the Buyer (as amended on
April 12, 2002, the "Confidentiality Agreement"); provided, however, that the
Buyer shall not be in breach of the Confidentiality Agreement if, following the
Closing, it uses Proprietary Information (as defined in the Confidentiality
Agreement) that is or was developed for, used by, or otherwise related to the
operations of the Company; provided, further, that notwithstanding the
foregoing, in no event shall the Buyer or any Buyer Subsidiary (including after
the Closing, the Company) directly disclose any such Proprietary Information in
any manner that is inconsistent with paragraph (iv) of the Acknowledgment and
Amendment to the Confidentiality Agreement dated April 12, 2002 (except for
disclosures made after the Closing to either Robert Haas or Violet Vela Divin
but, in either case, only if such person shall have been hired by the Company
and except for disclosures of (i) employee information related to Affected
Employees, (ii) purchase contracts for goods and services of the Company that
were in effect prior to the Closing, (iii) work orders of the Company relating
to the balance sheet of the Company at the Closing, and (iv) such other
information the disclosure of which is approved by the Seller and DQE).

          Section 6.2 Regulatory Matters. The Seller and the Buyer shall
cooperate and use all commercially reasonable efforts to promptly prepare and
file all necessary documentation, to effect all necessary applications, notices,
petitions, filings and other documents, and to use all commercially reasonable
efforts to obtain all necessary permits,

                                       22

<PAGE>

consents, approvals and authorizations of all Governmental Authorities necessary
or advisable to obtain the Seller Required Statutory Approvals and the Buyer
Required Statutory Approvals; provided, however, that the Seller and the Buyer
shall cooperate to prepare and file any such applications, notices, petitions,
filings and other documents timely in order to obtain all such approvals on or
before the Initial Termination Date (as defined in Section 8.1(c)) and shall
thereafter cooperate to diligently prosecute all such applications, notices,
petitions, filings and other documents. The Buyer shall not be required to
dispose of or change any portion of its existing business or to incur any other
burden expense to obtain a Seller Required Statutory Approval and the Seller
shall not be required to dispose of or change any portion of its existing
business or to incur any other burden expense to obtain a Buyer Required
Statutory Approval. The Buyer shall be precluded from including in any
application for regulatory approval contingencies relating to rate treatment of
acquisition premiums.

          Section 6.3 Consents. The Seller and the Buyer agree to use all
commercially reasonable efforts to obtain the Seller Required Consents and the
Buyer Required Consents, respectively, and to cooperate with each other in
connection with the foregoing. The Buyer shall not be required to dispose of or
change any portion of its existing business or to incur any other burden expense
to obtain a Seller Required Consent and the Seller shall not be required to
dispose of or change any portion of its existing business or to incur any other
burden expense to obtain a Buyer Required Consent.

          Section 6.4 Directors' and Officers' Indemnification.

               (a) Indemnification. To the fullest extent permitted by law, from
and after the Closing Date, all rights to indemnification existing immediately
prior to the Closing in favor of the current and former employees, agents,
directors or officers of Services I, Services II, Services, LP and each Company
Subsidiary (each, a "Company Indemnified Party" and, collectively, the "Company
Indemnified Parties") with respect to their activities as such prior to or on
the Closing Date, as provided in Services I's, Services II's, Services, LP's and
each Company Subsidiary's respective certificates of formation, operating
agreement, or other organizational documents in effect on the date of such
activities or otherwise in effect on the date hereof, shall survive the Closing
and shall continue in full force and effect for a period of not less than six
(6) years from the Closing Date, provided that, in the event any claim or claims
are asserted or made within such six (6) year period, all such rights to
indemnification in respect of any claim or claims shall continue until final
disposition of such claim or claims. For the avoidance of doubt, liabilities and
obligations of the Company to Company Indemnified Parties resulting from the
rights to indemnification contemplated by this Section 6.4 and attributable to
pre-Closing activities shall be Buyer Indemnifiable Losses and subject to the
Seller's and DQE's indemnification obligations under Article IX, recognizing
that such indemnification obligations are always subject to the limitations and
restrictions contained in Articles IX and X.

               (b) Insurance. For a period of six (6) years after the Closing
Date, DQE or the Seller shall maintain policies of directors' and officers'
liability insurance for those Persons covered by such policies maintained by the
Seller or DQE on behalf of the Company immediately prior to the Closing in
respect of pre-Closing acts or omissions on terms no less favorable than the
terms of such current insurance coverage.

                                       23

<PAGE>

               (c) Successors. In the event that after the Closing Date,
Services I, Services II, Services, LP or any Company Subsidiary or any of their
respective successors or assigns (i) consolidates with or merges into any other
Person or entity and shall not be the continuing or surviving corporation or
entity of such consolidation or merger or (ii) transfers all or substantially
all of its properties and assets to any Person or entity, then and in either
such case, proper provisions shall be made so that the successors and assigns of
Services I, Services II, Services, LP or any such Company Subsidiary, as the
case may be, shall assume the obligations set forth in this Section 6.4.

               (d) Benefit. The provisions of this Section 6.4 are intended to
be for the benefit of, and shall be enforceable by, each Company Indemnified
Party, his or her heirs and his or her representatives.

          Section 6.5 Public Announcements. Except as may be required by law,
applicable rules and regulations, or by obligations pursuant to any listing
agreement with or rules of any national securities exchange, DQE, the Seller and
the Buyer shall consult with each other prior to issuing any press releases or
otherwise making public announcements with respect to this Agreement and the
transactions contemplated hereby and shall keep the terms of this Agreement
confidential prior to Closing and shall not make any disclosure of this
Agreement to any Person. The Seller and the Buyer shall consult with each other
concerning the means by which the Company's employees, customers, suppliers and
other Persons dealing with the Company will be informed of the transaction
contemplated by this Agreement and representatives of the Buyer shall have the
right to be present for any such communication at any general meeting of the
employees.

          Section 6.6 Workforce Matters.

               (a) Prior to the Closing, the Buyer shall make a "qualifying
offer" of employment as that term is defined in the AquaSource Severance Policy
dated January 1, 2002 (the "Severance Policy" and, such qualifying offer, a
"Qualifying Offer") to each of the employees of the Seller identified in Section
6.6(a) of the Seller Disclosure Schedule (such individuals, the "Affected
Employees"). The Qualifying Offers shall be subject to Closing and contingent on
the Affected Employee satisfying the Buyer's drug testing policy and other
requirements imposed by applicable law, such as the Immigration Reform and
Control Act of 1986, as applicable (the "Hiring Conditions"). Subject to Closing
and satisfaction of the applicable Hiring Conditions, such Qualifying Offers
shall be accepted or rejected by the Affected Employees prior to the Closing
Date, to be effective immediately after the Closing. In connection with the
hiring process for Affected Employees, the Buyer shall comply with applicable
laws pertaining to labor and employment, including, without limitation, Title
VII of the Civil Rights Act of 1964, as amended, the Age Discrimination in
Employment Act, the Americans With Disabilities Act, the Rehabilitation Act and
comparable state and local laws.

               (b) Effective immediately after the Closing, the Company shall
assume, and continue in effect for a period of not less than twelve (12) months
from the Closing Date, the Severance Policy for the benefit of all Affected
Employees who have accepted Qualifying Offers and satisfied the Hiring
Conditions (the "Severance Obligations"), except that for purposes of the
assumption, all references in the Severance Policy to "AquaSource" shall be to
the Company,

                                       24

<PAGE>

and all references to "any DQE Subsidiary" shall be to any Buyer Subsidiary. If
any Affected Employee does not accept a Qualifying Offer or does not satisfy the
Hiring Conditions, then the Buyer shall have no further obligation to such
Affected Employee or to the Seller or DQE with regard to such Affected Employee.
For the avoidance of doubt, liabilities and obligations in respect of Affected
Employees who do not accept a Qualifying Offer or satisfy the applicable Hiring
Conditions shall be Buyer Indemnifiable Losses and subject to the Seller's and
DQE's indemnification obligations under Article IX, recognizing that such
indemnification obligations are always subject to the limitations and
restrictions contained in Articles IX and X. As between the Seller and the
Buyer, neither the Seller nor DQE shall be obligated to provide any severance or
separation pay benefits to any Affected Employee who has accepted a Qualifying
Offer and satisfied the Hiring Conditions on account of any termination of such
Affected Employee's employment after the Closing. Pursuant to Section 10 of the
Retention Agreements, effective upon the Closing, the Company hereby assumes and
agrees to perform the Seller's obligations under the Retention Agreements in the
same manner and to the same extent that the Seller would be required to perform,
had such succession not taken place. In addition, effective upon the Closing,
(i) DQE and the Seller hereby assign to the Company those agreements set forth
in Section 3.10(c) of the Seller Disclosure Schedule and (ii) the Company hereby
assumes and agrees to perform the Seller's or DQE's obligations which arise
after the Closing under those agreements set forth in Section 3.10(c) of the
Seller Disclosure Schedule, provided, however, that DQE and the Seller retain
sufficient rights under such agreements necessary to satisfy their respective
obligations contemplated by the last sentence of Section 6.17(a). For the
avoidance of doubt, liabilities and obligations of DQE, the Seller or the
Company which arise after the Closing under the Retention Agreement and those
agreements set forth in Section 3.10(c) of the Seller Disclosure Schedule shall
be Seller Indemnifiable Losses and subject to the Seller's indemnification
obligations under Article IX, recognizing that such indemnification obligations
are always subject to the limitations and restrictions contained in Articles IX
and X.

               (c) The Buyer shall be responsible for providing any continuation
coverage required under the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended ("COBRA") in respect of Affected Employees who experience a
qualifying event (within the meaning of COBRA) after the Closing, except for
those Affected Employees who do not accept a Qualifying Offer or who do not
satisfy the Hiring Conditions. The Buyer shall not have any further
responsibility for compliance with the continuation coverage requirements under
COBRA with respect to any other employees of the Seller or DQE. The Seller shall
be responsible for providing continuation coverage required under COBRA in
respect of Affected Employees who experience a qualifying event (within the
meaning of COBRA) before the Closing Date and in respect of Affected Employees
who do not accept a Qualifying Offer or who do not satisfy the Hiring
Conditions.

               (d) The Seller shall be responsible for any notices required to
be given under, or otherwise comply with, the WARN Act or similar statutes or
regulations of any jurisdiction relating to any "plant closing" or "mass layoff"
or similar triggering event ordered by DQE or the Seller with respect to the
Affected Employees prior to or on the Closing Date. The Buyer shall be
responsible for any notices required to be given under, or otherwise comply
with, the WARN Act or similar statutes or regulations of any jurisdiction
relating to any "plant closing" or "mass layoff" or similar triggering event
ordered by the Buyer or any Buyer Subsidiary after the Closing with respect to
the Affected Employees who have accepted a

                                       25

<PAGE>

Qualifying Offer and satisfied the Hiring Conditions. For the avoidance of
doubt, for purposes here, the parties intend for the "effective date" within the
meaning of the WARN Act to refer to and mean the Closing Date. To the extent
possible, the Buyer and the Seller agree to treat the Buyer as a "successor
employer" and the Seller or one or more of its affiliates as a "predecessor
employer" within the meaning of Sections 3121(a)(1) and 3306(b)(1) of the Code,
with respect to Affected Employees, for purposes of Taxes imposed under the
United States Federal Unemployment Tax or the United States Federal Insurance
Contributions Act. Provided that the Buyer fully performs its obligations to
make Qualifying Offers and to employ Affected Employees who accept such
Qualifying Offers pursuant to this Section 6.6, the Seller and DQE shall,
jointly and severally, indemnify and hold harmless the Buyer against any
liabilities related to any WARN Act obligations arising from the transactions
contemplated hereby attributable to the actions of the Seller or DQE.

               (e) The Buyer expressly agrees that (i) from the date hereof
until the first anniversary of the Closing Date, it will not directly or
indirectly solicit for employment, other than through solicitations made to the
general public, any of those persons listed on Section 6.6(e) of the Seller
Disclosure Schedule, and from the Closing Date until the first anniversary of
the Closing Date, it will cause the Company not to directly or indirectly
solicit for employment, other than through solicitations made to the general
public, those persons listed on Section 6.6(e) of the Seller Disclosure Schedule
and (ii) from the date hereof until the first anniversary of the Closing Date,
it will not employ any of those persons listed on Section 6.6(e) of the Seller
Disclosure Schedule, unless it shall have first given notice to the Seller of
its intent to make an offer of employment to any such persons, and, from the
Closing Date until the first anniversary of the Closing Date, it will cause the
Company not to employ any of those persons listed on Section 6.6(e) of the
Seller Disclosure Schedule, unless it shall have first given notice to the
Seller of its intent to make an offer of employment to any such persons.

          Section 6.7 Seller Plans.

               (a) Continued Employment; Service Credit. The Buyer does not,
indirectly or directly, assume or otherwise take responsibility for contribution
to benefits under, COBRA continuation coverage under, or the administration,
maintenance, or sponsorship of, any Seller Plan other than the Severance
Obligations and the Retention Agreements, nor shall there be any transfer of
assets or liabilities of any Seller Plan to any plan, program or arrangement
maintained by the Buyer or any of its affiliates. For the avoidance of doubt,
liabilities and obligations of the Seller Plans (other than the Severance
Obligations and the Retention Agreements) shall be Buyer Indemnifiable Losses
and subject to the Seller's and DQE's indemnification obligations under Article
IX, recognizing that such indemnification obligations are always subject to the
limitations and restrictions contained in Articles IX and X. However, if any
Affected Employee becomes a participant in any employee benefit plan, practice
or policy of the Buyer or any of its affiliates to the extent reasonably
permitted by applicable law and existing insurance contracts, such Affected
Employee shall be given credit under such plan for all service prior to the
Closing Date with the Company, any of its affiliates, any ERISA Affiliate or any
predecessor employer to the extent such credit was given by the Company, any of
its affiliates, any ERISA Affiliate or any predecessor employer under a Seller
Plan, and for all service with the Buyer or any of its affiliates on and after
the Closing Date but prior to the time such employee becomes such a participant,
for purposes of determining eligibility, vesting,

                                       26

<PAGE>

benefit accrual and for all other purposes for which such service is either
taken into account or recognized; provided, however, such service need not be
credited to the extent it would result in a duplication of benefits, including
for purposes of benefit accrual under defined benefit plans. Further, the Buyer
shall, and shall cause its affiliates to, to the extent reasonably permitted by
applicable law and existing insurance contracts, (i) waive all limitations as to
preexisting conditions exclusions and waiting periods with respect to
participation and coverage requirements applicable to each Affected Employee
under any welfare plan or welfare benefit plan in which the Affected Employee
participates on or after the Closing Date, except to the extent of limitations
or waiting periods that are already in effect with respect to the Affected
Employee as of the Closing Date under the Seller Plans and that have not been
satisfied as of the Closing Date and (ii) credit each Affected Employee for any
co-payments and deductibles paid prior to the Closing Date in satisfying any
applicable deductible or out-of-pocket requirements for the year in which the
Closing Date occurs under any welfare plan or welfare benefit plan in which the
Affected Employee participates on or after the Closing Date. The parties
acknowledge that the welfare plans which the Buyer will make available to the
Affected Employees will provide benefits substantially similar to those provided
by the welfare plans of the Buyer and the Buyer Subsidiaries for their current
employees. As of the Closing, the Company and its affiliates shall cease to
provide coverage and benefits for Affected Employees and their dependents and
beneficiaries under any benefit plan maintained by the Seller or DQE or any of
their respective affiliates, except as required by applicable law. The
provisions of this Section 6.7 shall not create or modify any Seller Plan (other
than the Severance Obligations) or employee benefit plans or agreements of the
Buyer.

               (b) Continuation of Agreements. The Buyer shall, and shall cause
the Company to, assume and honor the obligations arising under the Severance
Obligations and the Retention Agreements according to the terms thereof.

          Section 6.8 Tax Treatment. Neither the Seller nor the Buyer shall make
or file any election under Section 338 of the Code (or any similar provision of
the law of any state or other taxing jurisdiction) with respect to the purchase
of the Membership Interests (or the acquisition of shares in any Company
Subsidiary) in connection with the transactions contemplated by this Agreement.
For purposes of all Tax Returns and other applicable filings, the Buyer and the
Seller will each report the transactions contemplated hereby as a purchase and
sale, respectively, of the Membership Interests.

          Section 6.9 Tax Indemnity and Tax Returns. Notwithstanding any other
provision of this Agreement to the contrary, the Seller and DQE shall, jointly
and severally, indemnify, defend and hold harmless each Buyer Indemnitee (as
defined in Section 9.1(a)), and the Buyer shall indemnify, defend and hold
harmless each Seller Indemnitee (as defined in Section 9.1(b)) from and against
any and all of the liabilities of the Seller and DQE, and the Buyer,
respectively, as set forth below:

               (a) The Seller and DQE shall be liable for, shall pay to the
appropriate Tax authorities (or shall pay to the Company as a reimbursement of
Taxes paid to the appropriate Tax authorities for a Straddle Period (as defined
below) Tax Return), and shall indemnify and hold the Buyer and the Company
harmless against, all Taxes of the Company that relate to (i) the taxable
periods ending before or on the Closing Date (other than Taxes attributable to

                                       27

<PAGE>

transactions not in the ordinary course of business occurring after the Closing
which are effectuated or initiated by the Buyer), (ii) any taxable period that
includes but does not end on the Closing Date (a "Straddle Period"), but only to
the extent that such Taxes relate to the portion of such Straddle Period up to
and including the Closing Date, and (iii) any liability for Taxes of the
consolidated group of which DQE or the Seller is the common parent arising under
Treasury Regulations section 1.1502-6 (or any similar provision of state, local
or foreign law), as a transferor or successor, by contract or otherwise. The
Seller shall be entitled to all Tax refunds (including interest) attributable to
the taxable periods for which it is liable.

               (b) The Buyer shall be liable for, shall pay to the appropriate
Tax authorities, and shall indemnify and hold the Seller and DQE harmless
against all Taxes of the Company that relate to (i) the taxable periods that
begin after the Closing Date (including, for this purpose, any Taxes
attributable to transactions not in the ordinary course of business occurring
after the Closing which are effectuated or initiated by the Buyer) and (ii) the
portion of any Straddle Period commencing with the first day after the Closing
Date. The Buyer shall be entitled to any Tax refund (including interest)
attributable to the taxable periods for which it is so liable.

               (c) The obligations of the parties to indemnify each other
pursuant to this Section 6.9 shall continue until the statutory period of
limitations (taking into account any extensions or waivers thereof) for the
assessment of Taxes, covered by this Section 6.9, has expired. Any payment due
to an indemnified party pursuant to this Section 6.9 shall be paid promptly by
the indemnifying party upon receipt of written notice and, for further
clarification, shall not be subject to, or included in, the Indemnity Basket (as
defined in Section 9.3(b)) or the Indemnity Cap (as defined in Section 9.3(b)).

               (d) No party shall take any action the purpose and intent of
which is to prejudice the defense of any claim subject to indemnification
hereunder or to induce a third party to assert a claim subject to
indemnification hereunder.

               (e) After the Closing, each of the Seller and the Buyer shall
notify the chief tax officer of the other party in writing (including by
telecopier) within ten (10) days of the receipt of any written notice of any
pending or threatened Audit (as defined below) which, if determined adversely,
could be grounds for indemnification under this Section 6.9 (a "Tax Claim");
provided, however, that any failure to give such notice shall not affect the
rights of the parties hereunder unless and to the extent such failure materially
and adversely affects the indemnifying party's right to participate in and
defend such Tax Claim. The Seller shall have the right at its expense to
participate in and control the conduct of any Tax Claim of or attributable to
the Company relating to taxable periods ending on or before the Closing Date and
to employ counsel of its own choice at its expense; provided, however, that the
Seller shall not settle any such Tax Claim or make or agree to any adjustment in
any manner without the consent of the Buyer, which consent shall not be
unreasonably withheld, conditioned or delayed; and provided, further, that the
Buyer shall have the right to participate in (but not to control) such Tax
Claim. If the Seller fails to participate in any Tax Claim of the Company
relating to taxable periods ending on or before the Closing Date for which
notice was provided pursuant to this Section

                                       28

<PAGE>

6.9(e), the Buyer may defend and settle such Tax Claim in such manner as it may
deem appropriate in its sole discretion. Except as set forth above in the first
sentence of this Section 6.9(e), the Buyer shall control the conduct of any Tax
Claim of the Company relating to any taxable period ending after the Closing
Date and may defend and settle such Tax Claim in such manner as it may deem
appropriate in its sole discretion. The term "Audit" means any audit, assessment
of Taxes, reassessment of Taxes, or other examination by any Governmental
Authority or any judicial or administrative proceedings or appeal of such
proceedings.

               (f) All indemnity payments made by DQE or the Seller to the
Buyer, or by the Buyer to the Seller, pursuant to this Agreement shall, to the
maximum extent permitted under the Code (or other applicable Tax law), be
treated for all Tax purposes as adjustments to the consideration paid with
respect to the Membership Interests.

               (g) The Seller shall prepare and file, or cause to be prepared
and filed, when due all Tax Returns that are required to be filed by or with
respect to the Company for taxable years or periods ending on or before the
Closing Date. The Buyer shall prepare and file, or cause to be prepared and
filed, when due all Tax Returns that are required to be filed by or with respect
to the Company for taxable years or periods ending after the Closing Date. Any
Tax Return required to be filed by the Buyer relating to any Straddle Period
shall be prepared based on past practice and submitted (with copies of any
relevant Schedules, work papers and other documentation then available) to the
Seller for the Seller's approval not less than thirty (30) days prior to the due
date for the filing of such Tax Return, which approval shall not be unreasonably
withheld. The Seller and the Buyer shall make available all books and records
and cooperate with each other as reasonably necessary for the preparation and
filing of any Tax Returns relating to the Company.

               (h) Except as otherwise provided in this Agreement, any tax
sharing agreement between DQE and/or the Seller (including any of its
Subsidiaries) and the Company will be terminated with respect to the Company as
of the Closing Date, and the Company shall not have any obligation after the
Closing Date to make any payment under any such tax sharing agreement.

          Section 6.10 Transfer Taxes. Notwithstanding any other provision of
this Agreement to the contrary, the Buyer shall pay (a) all transfer (including
real property transfer and documentary transfer) Taxes and fees imposed with
respect to the transactions contemplated hereby and (b) all sales, use, gains
(including state and local transfer gains), excise and other transfer or similar
Taxes imposed with respect to the transactions contemplated hereby; provided,
however, that the Buyer shall not be responsible for any, and the Seller shall
pay all, costs, fees or Taxes imposed in respect of the transfer of the Excluded
Assets and the Integrated Assets, as contemplated by Section 5.3 of this
Agreement. The Seller shall execute and deliver to the Buyer, and the Buyer
shall execute and deliver to the Seller at the Closing any certificates or other
documents as the requesting party may reasonably request in order to perfect any
exemption from any such transfer, documentary, sales, use, gains, excise or
other Taxes, or to otherwise comply with any applicable reporting requirements
with respect to any such Taxes.

          Section 6.11 Financial Information.

               (a) After the Closing, upon reasonable written notice, the Buyer
and the Seller shall furnish or cause to be furnished to each other and their
respective accountants,

                                       29

<PAGE>

counsel and other Representatives, during normal business hours, such
information (including records pertinent to the Company) as is reasonably
necessary for financial reporting and accounting matters of the party to whom
information is furnished.

               (b) At the Closing, all books and records of the Company,
including all financial and accounting information and all of the books,
records, files and other information maintained with respect to the business of
the Company, will be either delivered to Buyer or made available for pickup by
Buyer. The Buyer shall retain all such books and records of the Company for such
period after the Closing Date as Buyer may determine, provided that before
disposing of such books or records, the Buyer shall give notice of its intent to
do so to the Seller and give the Seller an opportunity for thirty (30) days
after such notice to remove and retain all or any part of such books or records
as the Seller may select.

               (c) Without limiting the generality of the provisions of Section
6.16(b) below, any information provided by the Buyer to the Seller under the
provisions of this Section 6.11 shall be Confidential Information of the Company
(as defined in Section 6.16(b)).

          Section 6.12 Transition Services. Except as agreed to in writing by
the Seller and the Buyer, all data processing, accounting, insurance, banking,
personnel, legal, communications and other products and services provided to the
Company by the Seller or any affiliate of the Seller, including any agreements
or understandings (written or oral) with respect thereto, shall terminate
simultaneously with the Closing without any further action or liability on the
part of the parties thereto. Notwithstanding the foregoing, in the absence of a
written agreement, at the Buyer's request, the Seller shall provide, for a
period of six (6) months after the Closing, services (similar to those
contemplated by the preceding sentence as shall be mutually agreed to by the
parties) to the Company, which services, at the Buyer's request, shall be
provided at a price for such services that is equal to DQE's or the Seller's
Actual Cost (as defined below) for such services, as the case may be, to be paid
on a monthly basis by the Buyer to DQE or the Seller. The term "Actual Cost"
shall mean the sum of (A) the reasonable costs or expenses actually incurred by
the Seller or DQE attributable to the provision of transition services to the
Buyer, including (i) the reasonable salary and benefits for personnel performing
transition services for those hours when such personnel are performing
transition services, (ii) reasonable payments to temporary contract employees
for, or related to, transition services, and (iii) reasonable payments to
vendors and other third parties for, or related to, transition services, and (B)
costs of the Seller or DQE, including all overheads, that cannot be specifically
identified with a particular service or product provided to the Buyer but that
are reasonably allocable to the products or services rendered by the Seller or
DQE. At the request of the Buyer prior to Closing, the Seller and the Buyer will
cooperate to negotiate reasonable and mutually acceptable terms upon which
specific transition services will be provided after the Closing. In addition, at
the request of the Buyer prior to the Closing, the Seller and the Buyer will
cooperate to negotiate reasonable and mutually acceptable terms pursuant to
which the Seller, to the extent it retains, following the Closing, an ownership
or leasehold interest in the office building located in the Brittmoore-Tanner
Industrial Park, shall lease to the Company for a period of one (1) year
following the Closing Date (or such shorter period of time in the event that the
Seller's ownership or leasehold interest shall expire or terminate prior to the
conclusion of such one year period) such space in said office building that is
substantially equivalent to the space that the

                                       30

<PAGE>

Company is using in said building on the date hereof at a monthly rent payment
equal to the Seller's actual costs in respect of such space.

          Section 6.13 Update of the Seller Disclosure Schedule. The Seller may
from time to time prior to or on the Closing Date by notice in accordance with
this Agreement supplement or amend the Seller Disclosure Schedule, including one
or more supplements or amendments thereto, to promptly disclose any fact, event
or circumstance that has arisen, occurred or changed since the date of this
Agreement. Notwithstanding any other provision hereof to the contrary, the
Seller Disclosure Schedule and the representations and warranties made by the
Seller and DQE shall be deemed for all purposes to include and reflect such
supplements and amendments as of the date hereof and at all times thereafter,
including the Closing Date.

          Section 6.14 AquaSource Name. The Seller agrees that on the Closing
Date, and continuing until the sixth month anniversary of Closing Date, it shall
grant to Buyer the non-exclusive, fully-paid license to use the name
"AquaSource" or any derivations thereof that may have been used by the Company
on the date hereof anywhere in the United States of America.

          Section 6.15 Officer and Director Resignations. At the Closing, the
Seller will cause each officer and director of the Company to resign, or the
Seller shall remove each such officer and director, from such position as an
officer and/or director.

          Section 6.16 Non-Competition Covenants.

               (a) Prohibited Activities. Each of the Seller and DQE agree that
effective upon the Closing it will not, for a period of five (5) years following
the Closing Date, directly or indirectly, either in its own capacity or as a
partner, agent, consultant, through an Affiliate (as defined in Section
6.16(c)), or otherwise, or by means of any corporate device, do any of the
following, such activity constituting a "Prohibited Activity":

                   (i)   engage in any business identical to or which competes
     with the business providing water and wastewater services for municipal
     utility districts and municipalities, as such business was conducted by the
     Company during the period commencing on January 1, 2001 and continuing
     through the Closing Date, within 100 miles of the downtown business
     districts of the cities of Houston, Texas and Denver, Colorado, or engage
     in any business which would require use, directly or indirectly, of the
     Company's trade secrets or the Company's confidential or privileged
     information; provided, however, that the limitations provided for in this
     Section 6.16(a)(i) shall not apply to the Seller or DQE with regard to
     those systems within 100 miles of the downtown business district of the
     city of Houston, Texas listed on Exhibit 6.16(a)(i);

                   (ii)  solicit, induce, recruit or encourage any of Company's
     employees, consultants or independent contractors, to leave their
     employment or terminate their relationship with the Company, provided,
     however, that neither the Seller nor DQE shall be in violation of this
     Section 6.16(a)(ii) by continuing to utilize those consultants and
     independent contractors listed on Exhibit 6.16(a)(ii)

                                       31

<PAGE>

     or those consultants and independent contractors who, on the date of this
     Agreement, are performing services for DQE, the Seller or Subsidiaries of
     the Seller (other than the Company); or

                   (iii) solicit any person or entity which is, or which has
     been within one (1) year prior to the date of solicitation, a customer of
     the Company for the purpose of selling to such customer services or
     products which are in direct competition with the services or products
     offered by the Company prior to the Closing.

               (b) The Seller and DQE recognize and acknowledge that it and its
Affiliates had in the past, currently have, and in the future will have, access
to Confidential Information of the Company (as defined in this Section 6.16(b)).
The Seller and DQE agree that from the Closing Date until April 12, 2005 neither
the Seller nor any of its Affiliates will disclose such Confidential Information
to any person, firm, corporation, association or other entity for any purpose
whatsoever, unless (i) such Confidential Information becomes known to the public
generally through no fault of the Seller, or (ii) disclosure is required by law
or the order of any governmental authority, provided, that prior to disclosing
any Confidential Information pursuant to this clause (ii) the Seller shall, if
possible, give prior written notice thereof to the Buyer and provide the Buyer
with the opportunity to contest such disclosure. In the event of a breach or
threatened breach by the Seller or any of its Affiliates of the provisions of
this Section 6.16(b), the Buyer shall be entitled to an injunction restraining
the Seller or any of its Affiliates from disclosing, in whole or in part, such
Confidential Information. Nothing herein shall be construed as prohibiting the
Buyer from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages. For purposes of this Section 6.16(b),
"Confidential Information" shall mean all information of the Company which is
not generally known in the industries in which the Company is engaged during the
period commencing on January 1, 2001 and continuing through the Closing Date,
about the Company's business, products, processes and services, including,
without limitation, information relating to research, development, inventions,
computer program designs, flow charts, source and object codes, products and
services under development, pricing and pricing strategies, marketing and
selling strategies, servicing, purchasing, accounting, engineering, costs and
costing strategies, sources of supply, customer lists, customer requirements,
business methods or practices, training and training programs, proprietary
information, trade secrets, confidential information supplied from outside
sources, and related documentation, provided that, notwithstanding any other
provision of this Section 6.16(b), neither DQE nor the Seller shall be in
violation of this Section 6.6(b) by using information that is or was developed
for, used by, or otherwise related to the operations of DQE, the Seller or any
of their Affiliates other than the Company.

               (c) Reasonable Restraint. The Seller and DQE acknowledge that the
covenants in this Section 6.16 impose a reasonable restraint on the Seller and
DQE in light of the activities and business of the Buyer and the Company on the
date of the execution of this Agreement and the current plans of the Buyer and
the Company. The Seller and DQE further acknowledge that the covenants in this
Section 6.16 contain limitations as to time, geographic area and scope of
activity to be restrained that are reasonable and do not impose a greater
restraint than is necessary to protect the good will or other business interests
of the Buyer and the Company.

                                       32

<PAGE>

               (d) Affiliate. For purposes of this Section 6.16, the term
"Affiliate" shall mean a Person that directly or indirectly controls, or is
controlled by or under common control with the Seller or DQE; provided, that,
this Section 6.16 shall not apply to any Person who has ceased to be an
Affiliate for any reason. Control including the terms "controlled by" and "under
common control with," with respect to any entity includes officers, directors,
and 10% or greater owners, and other individuals or entities with the power to
direct or cause the direction of the management and policies of such entity,
directly or indirectly, whether through ownership of voting securities or by
contract or otherwise.

               (e) Equitable Relief. Because of the difficulty of measuring
economic losses to the Buyer or the Company as a result of a breach of the
covenants in this Section 6.16, and because of the immediate and irreparable
damage that could be caused to the Buyer or the Company for which they would
have no other adequate remedy, the Seller and DQE agree that the covenants in
this Section 6.16 may be enforced by Buyer or the Company by injunctions,
restraining orders and other equitable actions.

               (f) Severability; Reformation; Survival. The covenants in this
Section 6.16 are severable and separate, and the unenforceability of any
specific covenant shall not affect the continuing validity and enforceability of
any other covenant. In the event that any court of competent jurisdiction shall
determine that the scope, time or territorial restrictions set forth in this
Section 6.16 are unreasonable, then it is the intention of the parties that such
restrictions be enforced to the fullest extent which the court deems reasonable
and this Agreement shall thereby be reformed. The covenants in this Section 6.16
shall survive the Closing.

               (g) Material Covenants. The Seller and DQE acknowledge that their
agreement with the covenants in this Section 6.16 are material conditions to
Buyer's agreement to execute and deliver this Agreement and to consummate the
transactions contemplated hereby, are essential elements of this Agreement and
without the agreement of Seller and DQE to comply with such covenants, Buyer
would not have agreed to purchase the Membership Interests pursuant to this
Agreement.

               (h) Independent Covenants. All of the covenants in this Section
6.16 shall be construed as an agreement independent of any other provision in
this Agreement, and the existence of any claim or cause of action of Seller or
DQE against Buyer, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by Buyer of such covenants. It is
specifically agreed that the respective periods during which the covenants of
the Seller or DQE made in this Section 6.16 shall survive and shall be computed
by excluding from such computation any time during which Seller or DQE is in
violation of any provision of this Section 6.16. The covenants contained in this
Section 6.16 shall not be affected by any breach of any other provision of this
Agreement by any party hereto.

          Section 6.17 Enforcement of Other Covenants.

               (a) The Buyer may attempt to negotiate agreements with Bryan K.
Chapline, Kenneth W. Lindsey, James L. Coursey, Robert G. Haas, and Randolph S.
Jones (the "Designated Employees"), which agreements will become effective only
upon the Closing and will include covenants not to compete, on terms mutually
acceptable to the Buyer and each

                                       33

<PAGE>

Designated Employee. Prior to and after the Closing, the Seller shall cooperate
with the Buyer and use all actions reasonably necessary to enforce the
"Covenants Against Competition" set forth in the agreements listed in Section
3.10(c) of the Seller Disclosure Schedule, including by seeking legal damages
and/or injunctions or other equitable relief. The Seller and DQE shall, prior to
the Closing and for a period of one (1) year after the Closing, cooperate with
the Buyer and the Company and use all actions reasonably necessary to enforce
David Beyer's existing covenants not to compete for the benefit of the Company.

               (b) The Buyer shall reimburse the Seller or DQE, as applicable,
for any reasonable costs and expenses, including reasonable legal fees, incurred
by the Seller or DQE, as applicable, after the Closing in complying with their
respective obligations set forth in Section 6.17(a).

          Section 6.18 Surety Bonds.

               (a) After the Closing, the Buyer shall, and shall cause the
Company to, use all commercially reasonable efforts to recover and replace those
surety bonds listed in Exhibit 6.18(a) and to have such surety bonds returned to
Seller within ninety (90) calendar days of the Closing Date.

               (b) The Buyer expressly acknowledges that, after the Closing, the
Seller and/or DQE may cancel those surety bonds listed in Exhibit 6.18(b)
without notice to the Buyer, subject to the terms of the bond documents.

               (c) After the Closing, the Buyer shall, and shall cause the
Company to, use all commercially reasonable efforts to replace the Seller as
guarantor under that certain Marshall Office Park II Lease Agreement between
MOPII, B1, LLC and AquaSource Services, LP, dated November 13, 2001.

          Section 6.19 Further Assurances. Each party will, and will cause its
Subsidiaries to, execute such further documents or instruments and take such
further actions as may reasonably be requested by any other party in order to
consummate the transaction contemplated hereby in accordance with the terms
hereof or otherwise perform those obligations required hereunder. In the event
that any asset reflected in the Company Financial Statements to be conveyed,
assigned, transferred and delivered hereunder to the Company shall not have been
so conveyed, assigned, transferred and delivered to the Company at the Closing,
the Seller shall as promptly as practicable after the Closing Date convey,
assign, transfer and deliver such asset to the Company at which time the Buyer
shall cause the Company to assume all liabilities and obligations, and be
entitled to all benefits, associated therewith that are due, or received, after
(but not before) such assignment, transfer and delivery and such asset shall
thereafter be deemed to be an Integrated Asset for all other purposes under this
Agreement, including Article IX, except that they shall be deemed to have been
included among the Integrated Assets as of the date of such assignment and
transfer.

                                   ARTICLE VII
                                   CONDITIONS

          Section 7.1 Conditions to Each Party's Obligation to Effect the
Closing. The respective obligations of each party to effect the Closing shall be
subject to the satisfaction on or prior to the Closing Date of the following
conditions, except, to the extent permitted by applicable law, that such
conditions may be waived in writing pursuant to Section 10.3 of this Agreement:

               (a) No Injunction. No temporary restraining order or preliminary
or permanent injunction or other order by any federal or state court preventing
consummation of the transactions contemplated hereby shall have been issued and
be continuing in effect, and the transactions contemplated hereby shall not have
been prohibited under any applicable federal or state law or regulation.

               (b) Statutory Approvals. The Seller Required Statutory Approvals
and the Buyer Required Statutory Approvals shall have been obtained at or prior
to the Closing Date, such approvals shall have become Final Orders (as defined
below) and such Final Orders shall not, individually or in the aggregate, impose
terms or conditions (other than the preclusion of recovery of an acquisition
premium) which would have a material adverse effect on the business, operations,
properties, assets, financial condition, or results of operations of the Company
and the Buyer and their respective Subsidiaries taken as a whole. A "Final
Order" means action by the relevant regulatory authority which has not been
reversed, stayed, enjoined, set aside, annulled or suspended, with respect to
which any waiting period prescribed by law before the transactions contemplated
hereby may be consummated has expired, and as to which all conditions to the
consummation of such transactions prescribed by law, regulation or order have
been satisfied.

               (c) Assignment, Transfer and Delivery of Excluded Assets and
Assumption of Related Liabilities. All of Services I's, Services II's, Services,
LP's and the Company Subsidiaries' right, title and interest in and to the
Excluded Assets shall have been assigned and transferred, and all such Excluded
Assets shall have been delivered, to the Seller or such third party as the
Seller may designate, and the Seller or such third party, as the case may be,
shall have assumed all of the obligations and liabilities of Services I,
Services II, Services, LP and the Company Subsidiaries in respect of such
Excluded Assets, as contemplated by Section 5.3(a) of this Agreement; provided,
however, that if any such assignment, transfer or delivery requires the approval
or consent of any third party which shall not have been obtained, the parties
shall use commercially reasonable efforts, at the Seller's expense, to secure
such consent or otherwise effect such assignment, transfer and delivery
following the Closing and the Seller shall fully indemnify the Buyer and the
Company for and against any consequences of the failure to secure such consent
prior to the Closing. For the avoidance of doubt, liabilities and obligations of
DQE, the Seller or the Company relating to the Excluded Assets shall be Buyer
Indemnifiable Losses and subject to the Seller's and DQE's indemnification
obligations under Article IX.

               (d) Assignment, Transfer and Delivery of Integrated Assets and
Assumption of Related Liabilities. All of the Seller's and any Subsidiary of the
Seller's right,

                                       35

<PAGE>

title and interest in and to the Integrated Assets shall have been assigned and
transferred, and all such Integrated Assets shall have been delivered, to the
Company, and the Company shall have assumed all of the performance obligations
of DQE, the Seller, any Subsidiary of the Seller and the Company which arise
after the Closing and relate to the contracts included among the Integrated
Assets listed on Section 3.3 of the Seller Disclosure Schedule and all
liabilities of DQE, the Seller, any Subsidiary of the Seller and the Company,
direct or indirect, known or unknown, absolute or contingent, which arise after
the Closing and relate to the Integrated Assets listed on Section 3.3 of the
Seller Disclosure Schedule, as contemplated by Section 5.3(b) of this Agreement;
provided, however, that if any such assignment, transfer or delivery requires
the approval or consent of any third party which shall not have been obtained,
the parties shall use commercially reasonable efforts, at the Seller's expense,
to secure such consent or otherwise effect such assignment, transfer and
delivery following the Closing and the Seller shall fully indemnify the Buyer
and the Company for and against any consequences of the failure to secure such
consent prior to the Closing. For avoidance of doubt, liabilities and
obligations of DQE, the Seller, any Subsidiary of the Seller or the Company
relating to the Integrated Assets which arise prior to the Closing shall be
Buyer Indemnifiable Losses and subject to the Seller's and DQE's indemnification
obligations under Article IX, and liabilities and obligations of DQE, the
Seller, any Subsidiary of the Seller or the Company relating to the Integrated
Assets which arise after the Closing shall be Seller Indemnifiable Losses and
subject to the Buyer's indemnification obligations under Article IX, recognizing
that all such indemnification obligations are always subject to the limitations
and restrictions contained in Articles IX and X.

          Section 7.2 Conditions to Obligation of the Buyer to Effect the
Closing. The obligation of the Buyer to effect the Closing shall be further
subject to the satisfaction, on or prior to the Closing Date, of the following
conditions, except as may be waived by the Buyer in writing pursuant to Section
9.3:

               (a) Performance of Obligations of the Seller. The Seller (and/or
DQE or the Company) will have performed in all material respects its agreements
and covenants contained in or contemplated by this Agreement which are required
to be performed by it at or prior to the Closing.

               (b) Representations and Warranties of the Seller. The
representations and warranties of the Seller (and DQE in Section 3.4) set forth
in this Agreement shall be true and correct (i) on and as of the date hereof and
(ii) on and as of the Closing Date with the same effect as though such
representations and warranties had been made on and as of the Closing Date
(except for representations and warranties that expressly speak only as of a
specific date or time which need only be true and correct as of such date or
time provided that the Seller's representations and warranties in Section 3.3
shall be true and correct on and as of the Closing Date) except in each of cases
(i) and (ii) for such failures of representations or warranties to be true and
correct (without giving effect to any materiality qualification or standard
contained in any such representations and warranties) which, individually or in
the aggregate, would not result in a Company Material Adverse Effect.

               (c) Closing Certificates of the Seller. The Buyer shall have
received a certificate signed by a duly authorized officer on behalf of the
Seller and DQE, dated the Closing

                                       36

7.2(b) have been satisfied.

               (d) Company Material Adverse Effect. No Company Material Adverse
Effect shall have occurred and there shall exist no facts or circumstances that,
individually or in the aggregate, are reasonably likely to have a Company
Material Adverse Effect. For the purpose of this Section 7.2(d): (w) events,
facts or circumstances need not constitute, or be likely to constitute, a breach
of a representation or warranty in order to have, or be reasonably likely to
have, a Company Material Adverse Effect, (x) no materiality or knowledge
qualification or standard contained in the representations and warranties shall
be taken into account in determining whether or not events, facts or
circumstances, have, or are reasonably likely to have a Company Material Adverse
Effect, (y) if a Designated Employee is subject to a "Covenant Against
Competition" with the Seller, and such Designated Employee's employment with the
Seller is terminated prior to the Closing, then such termination of employment
or any impact on the Company resulting therefrom will not constitute a Company
Material Adverse Effect so long as the Seller and DQE are complying with their
obligations to use all actions reasonably necessary actions to enforce the
"Covenants Against Competition" set forth in the agreements listed in Section
3.10(c) of the Seller Disclosure Schedule, as contemplated by Section 6.17(a) of
this Agreement, and (z) the inability of the Company to own or operate its
assets in materially the same manner as such assets are owned or operated by the
Company on the date hereof resulting specifically from any change in law, rule
or regulation of any Governmental Authority, which change is made specifically
in order to enhance or protect the safety and security of water and wastewater
systems in light of concerns arising due to national or international
occurrences, and which change applies generally to parties providing water and
wastewater services for municipal utility districts and/or municipalities, will
be taken into account in determining whether or not there is, or there is
reasonably likely to be, a Company Material Adverse Effect.

               (e) The Seller Required Consents. The Seller Required Consents,
the failure of which to obtain would have a Company Material Adverse Effect,
shall have been obtained.

               (f) Additional Documents. Each of the following documents shall
have been delivered to the Buyer:

                   (i)   A certified copy of resolutions of the Seller's Board

     the transactions contemplated by this Agreement, and the authority of the
     parties acting on behalf of the Seller to execute and deliver documents in
     connection therewith;

                   (ii)  Certificates of Good Standing and Existence (or the
     equivalent) with respect to Services I, Services II, Services, LP and each
     Company Subsidiary, dated no earlier than five (5) business days prior to
     the Closing Date; and

subject to the satisfaction, on or prior to the Closing Date, of the following
conditions, except as may be waived by the Seller in writing pursuant to Section

               (a) Performance of Obligations of the Buyer. The Buyer (and/or
its appropriate Subsidiaries) will have performed in all material respects its
agreements and covenants contained in or contemplated by this Agreement which
are required to be performed by it at or prior to the Closing Date.

               (b) Representations and Warranties. The representations and
warranties of the Buyer set forth in this Agreement shall be true and correct
(i) on and as of the date hereof and (ii) on and as of the Closing Date with the

Effect shall have occurred and there shall exist no fact or circumstance that
would result in a Buyer Material Adverse Effect.

               (e) Buyer Required Consents. The Buyer Required Consents, the
failure of which to obtain would have a Buyer Material Adverse Effect, shall
have been obtained.

               (f) Additional Documents. Each of the following documents shall

     request for the purpose of facilitating or in connection with the Closing

                                  ARTICLE VIII
                                   TERMINATION

          Section 8.1 Termination. This Agreement may be terminated at any time
prior to the Closing Date:

               (a) by mutual written consent of the Seller and the Buyer;

               (b) by the Buyer or the Seller, if any state or federal law,
order, rule or regulation is adopted or issued, which has the effect, as
supported by the written opinion of outside counsel for such party, of
prohibiting the Closing, or by the Buyer or the Seller, if any court of
competent jurisdiction in the United States or any state shall have issued an
order, judgment or decree permanently restraining, enjoining or otherwise
prohibiting the Closing, and, in either case, if such order, rule, regulation,
judgment or decree shall have become final and nonappealable;

               (c) by the Buyer or the Seller, by written notice to the other
party, if the Closing shall not have occurred on or before sixty (60) days after
the date hereof (the "Initial Termination Date"); provided, however, that the
right to terminate the Agreement under this Section 8.1(c) shall not be
available to any party whose failure, or whose Affiliate's failure, to fulfill
any obligation under this Agreement shall have proximately contributed to the
failure of the Closing to occur on or before such date; and provided, further,
that if on the Initial Termination Date the conditions to the Closing set forth
in Sections 7.1(b), 7.2(e) and/or 7.3(e) shall not have been fulfilled but all
other conditions to the Closing shall be fulfilled or shall be capable of being
fulfilled, then the Initial Termination Date shall be extended to one hundred
twenty (120) days after the date hereof;

               (d) by the Buyer if, at the Closing, any breach or breaches of
any of the Seller's representations or warranties, covenants or agreements
result, or are reasonably likely to result, individually or in the aggregate, in
a Company Material Adverse Effect and such breach or breaches shall not have
been cured by the Seller or in respect of which the Seller shall not have agreed
to indemnify the Buyer (pursuant to which indemnity agreement, all Indemnifiable
Losses relating to, resulting from or arising out of such breach or breaches
shall be Buyer Indemnifiable Losses subject to the Seller's indemnification
obligations under Article IX but shall not be limited by, or taken into account
in determining whether Buyer Indemnifiable Losses exceed, the Indemnity Cap or
be limited by the Indemnity Period). For the avoidance of doubt, if at the
Closing there are any breaches of the Seller's representations and warranties
that do not result, or are not reasonably likely to result, individually or in
the aggregate, in a Company Material Adverse Effect, then following the Closing
all Indemnifiable losses relating to, resulting from or arising out of such
breaches, to the extent uncured by the Seller, shall be Buyer Indemnifiable
Losses subject to the Seller's indemnification obligations under Article IX,
recognizing that such indemnification obligations are always subject to the
limitations and restrictions contained in Articles IX and X.

               (e) by the Seller if, at the Closing any breach or breaches of
any of the Buyer's representations or warranties, covenants or agreements
result, or are reasonably like to result, individually or in the aggregate, in a
Buyer Material Adverse Effect and such breach or breaches shall not have been
cured by the Buyer or in respect of which the Buyer shall not have agreed to
indemnity the Seller (pursuant to which indemnity agreement all Indemnifiable
Losses relating to, resulting from or arising out of such breach or breaches
shall be Seller Indemnifiable Losses, subject to the Buyer's indemnification
obligations under Article IX but shall not be limited by, or taken into account
in determining whether Seller Indemnifiable Losses exceed, the Indemnity Cap or
be limited by the Indemnity Period). For the avoidance of doubt, if at the
Closing there are any breaches of the Buyer's representations and warranties
that do not result, or are not reasonably likely to result, individually or in
the aggregate, in a Buyer Material Adverse Effect, then following the Closing
all Indemnifiable Losses relating to, resulting from or arising out of such
breaches, to the extent uncured by the Buyer, shall be Seller Indemnifiable
Losses subject to the Buyer's indemnification obligations under Article IX,
recognizing that such indemnification obligations are always subject to the
limitations and restrictions contained in Articles IX and X.

               (f) by the Buyer if one or more supplements to or amendments of
any sections of the Seller Disclosure Schedule made by the Seller pursuant to
Section 6.13, individually or in the aggregate, materially and adversely affects
the benefits to be obtained by the Buyer under this Agreement.

          Section 8.2 Effect of Termination. In the event of termination of this
Agreement by either the Seller or the Buyer pursuant to Section 8.1 there shall
be no liability on the part of either the Seller or the Buyer or their
respective officers or directors hereunder, except that:

               (a) in the event of fraud or willful breach of this Agreement by
one party (the "Party at Fault"), or in the event of the failure of a condition
to a party's obligation to effect the Closing that results from the other
party's (also the "Party at Fault") willful breach of its obligations under this
Agreement, then the party who is not the Party at Fault shall have the right to
terminate this Agreement and pursue all available legal remedies against the
Party at Fault, which right shall survive termination unimpaired, and in
addition to the foregoing, upon such termination, the Party at Fault shall pay
the party who is not the Party at Fault the sum of one million dollars
($1,000,000).

               (b) Sections 8.2, 10.2, 10.4, 10.5, 10.8, 10.9, 10.10, 10.11,
10.12 and 10.13, and the agreement contained in the last sentence of Section 6.1
shall survive the termination.

          Section 9.3 Limitations on Indemnification.

               (a) Notwithstanding any other provision of this Agreement to the
contrary, the parties' obligations pursuant to this Article IX are, and at all
times shall be, subject to the limitations set forth in this Section 9.3. The
parties shall not be required to indemnify, defend or hold harmless any Buyer
Indemnitee or Seller Indemnitee, as the case may be, until the aggregate dollar
amount of the Buyer Indemnifiable Losses or Seller Indemnifiable Losses, as the
case may be determined taking into account all Indemnifiable Losses (except for
Indemnified Losses to which the Indemnity Cap does not apply) asserted against
or suffered by the Buyer Indemnitees or the Seller Indemnitees, as the case may
be, exceeds the Indemnity Basket (as defined in Section 9.3(b)), following which
the indemnifying party shall indemnify, defend and hold harmless the Buyer
Indemnitees or the Seller Indemnitees, as the case may be, only to the extent
that the aggregate amount of Buyer Indemnifiable Losses or the Seller
Indemnifiable Losses, as the case may be, exceeds the Indemnity Basket. In
addition, the Seller's and DQE's liability, taken together, for Buyer
Indemnifiable Losses and the Buyer's liability for Seller Indemnifiable Losses,
in either case, as contemplated by this Article IX shall in no event exceed an
aggregate amount of dollars equal to the Indemnity Cap (as defined in Section
9.3(b)).

               (b) As used in this Agreement, (i) the term "Indemnity Basket"
shall mean Two Hundred Thousand Dollars ($200,000), and (ii) the term "Indemnity
Cap shall mean Four Million, Two Hundred, Twenty-Five Thousand Dollars
($4,250,000). Notwithstanding any other provision of this Agreement to the
contrary, the Seller's and DQE's liability for the following Buyer Indemnifiable
Losses shall not be limited by, nor taken into account in determining whether
Buyer Indemnifiable Losses exceed the Indemnity Cap, shall not be limited by the
requirement to make a claim during the Indemnity Period and shall not be limited
by any requirement to meet or exceed the Indemnity Basket: Buyer Indemnifiable
Losses relating to (i) Excluded Assets, (ii) any and all liabilities and
obligations of the Seller or the Subsidiaries of the Seller (other than any
liabilities or obligations of the Seller (in respect of the Company), Services
I, Services II, Services, LP or any Company Subsidiary), (iii) indemnity
obligations of the Seller in respect of Taxes, as set forth in Section 6.9, (iv)
litigation or other legal proceedings (including any settlements or judgments in
respect thereof), existing or threatened, that are set forth in Section 3.7 of
the Seller Disclosure Schedule and all other litigation or other legal
proceedings (including any settlements or judgments in respect thereof), that
involve the Company and are based on facts or circumstances arising, existing or
occurring prior to the Closing, including any claims that were brought or could
have been brought in the litigation captioned Edward Wallace, et al v.
AquaSource, Inc., et al (Case No. 2001-05987), filed in the 270th Judicial
District Court of Harris County, Texas, (v) any indemnity given pursuant to the
first sentence of Section 8.1(d) and (vi) any fraud committed by DQE, the
Seller, Services I, Services II, Services, LP or any Company Subsidiary
(provided that the foregoing reference to Services I, Services II, Services, LP
or any Company Subsidiary refers to fraud committed prior to the Closing Date);
in addition, the Buyer's liability for the following Seller Indemnifiable Losses
shall not be limited by, nor taken into account in determining whether Seller
Indemnifiable Losses exceed the Indemnity Cap, shall not be limited by the
requirement to make a claim during the Indemnity Period, and shall not be
limited by any requirement to meet or exceed the Indemnity Basket: Seller
Indemnifiable Losses relating to (x) indemnity obligations of the Buyer in
respect of Taxes, as set forth in Section 6.9, (y) any indemnity given pursuant
to the first sentence of Section 8.1(e), and (z) any fraud committed by the
Buyer, any Buyer

                                       43

<PAGE>

Subsidiary, Services I, Services II, Services, LP or any Company Subsidiary
(provided that the foregoing reference to Services I, Services II, Services, LP
or any Company Subsidiary refers to fraud committed on or after the Closing
Date).

               (c) For the avoidance of doubt, if at any time during the
Indemnity Period, the amount of the Seller's and DQE's aggregate dollar amount
of liability for Buyer Indemnifiable Losses, taking into account all liability
for Buyer Indemnifiable Losses incurred by the Seller and DQE since the Closing
Date (other than those Buyer Indemnifiable Losses that are not limited by the
Indemnity Cap as contemplated by Section 9.3(b)), equals the Indemnity Cap, then
the Seller shall have no further obligation whatsoever to indemnify, defend or
hold harmless any Buyer Indemnitee in respect of any Buyer Indemnifiable Losses
that are subject to the Indemnity Cap; similarly, if at any time during the
Indemnity Period, the amount of the Buyer's aggregate liability for Seller
Indemnifiable Losses, taking into account all liability for Seller Indemnifiable
Losses incurred by the Buyer since the Closing Date (other than those Seller
Indemnifiable Losses that are not limited by the Indemnity Cap as contemplated
by Section 9.3(b)), equals the Indemnity Cap, then the Buyer shall have no
further obligation whatsoever to indemnify, defend or hold harmless any Seller
Indemnitee in respect of any Seller Indemnifiable Losses that are subject to the
Indemnity Cap.

               (d) Notwithstanding any other provision of this Agreement to the
contrary, any Buyer Indemnitee or Seller Indemnitee shall use commercially
reasonable efforts to mitigate all losses, damages and the like relating to a
claim under these indemnification provisions, including availing itself of any
defenses, limitations, rights of contribution, claims against third Persons and
other rights at law or equity. The Buyer Indemnitee's or Seller Indemnitee's, as
the case may be, commercially reasonable efforts shall include the reasonable
expenditure of money to mitigate or otherwise reduce or eliminate any loss or
expenses for which indemnification would otherwise be due, and the indemnifying
party shall, to the extent that Buyer Indemnifiable Losses or Seller
Indemnifiable Losses, as the case may be, exceed the Indemnity Basket, reimburse
the Buyer Indemnitee or Seller Indemnitee, as the case may be, for its
reasonable expenditures (except for any portion of the wages, salary, benefits,
overhead or other costs attributable to Buyer Indemnitee or Seller Indemnitee,
as the case may be, and its officers, directors, employees and agents) in
undertaking the mitigation and, subject to Section 9.3(b) shall, to such extent,
take such expenses into account in calculating the aggregate amount of the
Seller's and DQE's liability for the Buyer Indemnifiable Losses or the Buyer's
liability for the Seller Indemnifiable Losses, as the case may be.
Notwithstanding any other provision of this Agreement to the contrary, any Buyer
Indemnifiable Loss or Seller Indemnifiable Loss shall be net of (i) the dollar
amount of any insurance or other proceeds actually received by the Buyer
Indemnitee or any of its affiliates with respect to the Buyer Indemnifiable Loss
or by the Seller or DQE or any of their affiliates with respect to the Seller
Indemnifiable Loss, and (ii) income tax benefits to the Buyer Indemnitee, to the
extent realized by the Buyer Indemnitee, or to the Seller Indemnitee, to the
extent recognized by the Seller Indemnitee. Any Person seeking indemnity
hereunder shall, to the extent they have the right to do so under an insurance
policy, use commercially reasonable efforts to seek coverage (including both
costs of defense and indemnity) under applicable insurance policies with respect
to any such Buyer Indemnifiable Loss or Seller Indemnifiable Loss, as the case
may be.

<PAGE>

               (e) Notwithstanding any other provision of this Agreement to the
contrary, (i) except to the extent otherwise provided in Article VIII, the
rights and remedies of the parties under this Article IX are exclusive and in
lieu of any and all other rights and remedies which the parties may have under
this Agreement for monetary relief with respect to (A) any breach by the parties
of their respective representations and warranties and (B) the Indemnified
Liabilities, and (ii) except in the case of fraud, no party (nor any Buyer
Indemnitee or Seller Indemnitee) shall be entitled to recover from any other
party for any liabilities, damages, obligations, payments, losses, costs, or
expenses under this Agreement any amount in excess of the actual compensatory
damages, court costs and reasonable attorneys' and other advisor fees suffered
by such party (or Buyer Indemnitee or Seller Indemnitee, as the case may be).
Each party waives any right to recover incidental, special, exemplary and
consequential damages arising in connection with or with respect to this
Agreement (except in the case of fraud).

          Section 9.4 Defense of Claims. The parties agree that the provisions
set forth below in (a), (b) and (c) shall not apply to claims made in respect of
Excluded Assets or in respect of any litigation or other legal proceedings
(including any settlements or judgments in request thereof) contemplated by
Section 9.2(c)(i), but that such provisions shall apply to all other claims
under this Article IX.

          (a) (i) If any Buyer Indemnitee receives notice of the assertion or
     commencement of any claim, action or proceeding made or brought by any
     Person who is neither a party to this Agreement nor an affiliate of a party
     to this Agreement (a "Third Party Claim") with respect to which
     indemnification is to be sought from the Seller and DQE, the Buyer
     Indemnitee shall give the Seller and DQE reasonably prompt written notice
     thereof, but in any event such notice shall not be given later than
     forty-five (45) calendar days after the Buyer Indemnitee's receipt of
     written notice of such Third Party Claim, provided, that the failure to
     give such notice within such time period shall not relieve the Seller or
     DQE of any liability except to the extent the Seller or DQE is prejudiced
     by such failure. To the extent known, such written notice shall describe
     the nature of the Third Party Claim in reasonable detail and shall indicate
     the estimated amount, if practicable, of the Buyer Indemnifiable Loss that
     has been or may be sustained by the Buyer Indemnitee. The Seller and DQE
     will have the right to participate in or, by giving written notice to the
     Buyer Indemnitee, to elect to assume the defense of any Third Party Claim
     by the Seller's own counsel, the cost for which shall be borne by the
     Seller and DQE to the extent that Buyer Indemnifiable Losses exceed the
     Indemnity Basket and shall, to such extent, be taken into account in
     calculating the aggregate amount of the Seller's and DQE's liability for
     Buyer Indemnifiable Losses under the Indemnity Cap. The Buyer Indemnitee
     shall cooperate in good faith in such defense at such Buyer Indemnitee's
     own expense. If the Seller and DQE elect not to assume the defense of any
     Third Party Claim, the Buyer Indemnitee may compromise or settle such Third
     Party Claim over the objection of the Seller and DQE, which settlement or
     compromise shall conclusively establish the Seller's and DQE's liability
     pursuant to this Agreement.

              (ii) If any Seller Indemnitee receives notice of the assertion or
     commencement of a Third Party Claim with respect to which indemnification
     is to be sought from the Buyer, the Seller Indemnitee shall give the Buyer
     reasonably prompt written notice thereof, but in any event such notice
     shall not be

                                       45

<PAGE>

     given later than forty-five (45) calendar days after the Seller
     Indemnitee's receipt of written notice of such Third Party Claim, provided,
     that the failure to give such notice within such time period shall not
     relieve the Buyer of any liability except to the extent the buyer is
     prejudiced by such failure. To the extent known, such written notice shall
     describe the nature of the Third Party Claim in reasonable detail and shall
     indicate the estimated amount, if practicable, of the Seller Indemnifiable
     Loss that has been or may be sustained by the Seller Indemnitee. The Buyer
     will have the right to participate in or, by giving written notice to the
     Seller Indemnitee, to elect to assume the defense of any Third Party Claim
     by the Buyer's own counsel, the cost for which shall be borne by the Buyer
     to the extent that Seller Indemnifiable Losses exceed the Indemnity Basket
     and shall, to such extent, be taken into account in calculating the
     aggregate amount of the Buyer's liability for Seller Indemnifiable Losses
     under the Indemnity Cap. The Seller Indemnitee shall cooperate in good
     faith in such defense at such Seller Indemnitee's own expense. If the Buyer
     elects not to assume the defense of any Third Party Claim, the Seller
     Indemnitee may compromise or settle such Third Party Claim over the
     objection of the Buyer, which settlement or compromise shall conclusively
     establish the Buyer's liability pursuant to this Agreement.

          (b) (i) If, after a Buyer Indemnitee provides written notice to the
     Seller and DQE of any Third Party Claims, the Buyer Indemnitee receives
     written notice from the Seller or DQE that the Seller or DQE has elected to
     assume the defense of such Third Party Claim, the Seller and DQE will not
     be liable for any legal expenses subsequently incurred by the Buyer
     Indemnitee in connection with the defense thereof. Without the prior
     written consent of the Buyer Indemnitee, the Seller and DQE shall not enter
     into any settlement of any Third Party Claim that would lead to liability
     or create any financial or other obligation on the part of the Buyer
     Indemnitee for which the Buyer Indemnitee is not entitled to
     indemnification hereunder. If a firm offer is made to settle a Third Party
     Claim without leading to liability or the creation of a financial or other
     obligation on the part of the Buyer Indemnitee for which the Buyer
     Indemnitee is not entitled to indemnification hereunder and the Seller and
     DQE desire to accept and agree to such offer, the Seller and DQE shall give
     written notice to the Buyer Indemnitee to that effect. If the Buyer
     Indemnitee fails to consent to such firm offer within thirty (30) calendar
     days after its receipt of such notice, the Seller and DQE shall be relieved
     of their obligations to defend such Third Party Claim and the Buyer
     Indemnitee may contest or defend such Third Party Claim. In such event, the
     maximum liability of the Seller and DQE as to such Third Party Claim will
     be the amount of such settlement offer plus reasonable costs and expenses
     paid or incurred by the Buyer Indemnitee up to the date of said notice, at
     all time subject to the additional limitations on the Seller's and DQE's
     liability contained in this Article IX.

                   (ii)  If, after a Seller Indemnitee provides written notice
     to the Buyer of any Third Party Claims, the Seller Indemnitee receives
     written notice from the Buyer that the Buyer has elected to assume the
     defense of such Third Party Claim, the Buyer will not be liable for any
     legal expenses subsequently incurred by the Seller Indemnitee in connection
     with the defense thereof. Without the prior written consent of the Seller
     Indemnitee, the Buyer shall not enter into any settlement of any Third
     Party

                                       46

<PAGE>

     Claim that would lead to liability or create any financial or other
     obligation on the part of the Seller Indemnitee for which the Seller
     Indemnitee is not entitled to indemnification hereunder. If a firm offer is
     made to settle a Third Party Claim without leading to liability or the
     creation of a financial or other obligation on the part of the Seller
     Indemnitee for which the Seller Indemnitee is not entitled to
     indemnification hereunder and the Buyer desires to accept and agree to such
     offer, the Buyer shall give written notice to the Seller Indemnitee to that
     effect. If the Seller Indemnitee fails to consent to such firm offer within
     thirty (30) calendar days after its receipt of such notice, the Buyer shall
     be relieved of its obligation to defend such Third Party Claim and the
     Seller Indemnitee may contest or defend such Third Party Claim. In such
     event, the maximum liability of the Buyer as to such Third Party Claim will
     be the amount of such settlement offer plus reasonable costs and expenses
     paid or incurred by the Seller Indemnitee up to the date of said notice, at
     all time subject to the additional limitations on the Buyer's liability
     contained in this Article IX.

          (c) (i) Any claim that does not result from a Third Party Claim (a
     "Direct Claim") by a Buyer Indemnitee on account of a Buyer Indemnifiable
     Loss shall be asserted by giving the Seller and DQE reasonably prompt
     written notice thereof after the Buyer Indemnitee becomes aware of such
     Direct Claim, stating, to the extent known, the nature of such claim in
     reasonable detail and indicating the estimated amount, if practicable, but
     in any event such notice shall not be given later than forty-five (45)
     calendar days after the Buyer Indemnitee becomes aware of such Direct
     Claim, provided, that the failure to give such notice within such time
     period shall not relieve the Seller or DQE of any liability except to the
     extent the Seller or DQE is prejudiced by such failure, and the Seller and
     DQE shall have a period of thirty (30) calendar days from receipt of such
     notice within which to respond to such Direct Claim. If the Seller or DQE
     does not respond within such thirty (30) calendar day period, the Seller
     and DQE shall be deemed to have accepted, and shall be liable for, such
     claim. If the Seller and DQE reject such claim, the Buyer Indemnitee will
     be free to seek enforcement of its right to indemnification under this
     Agreement.

              (ii) Any Direct Claim by a Seller Indemnitee on account of a
     Seller Indemnifiable Loss shall be asserted by giving the Buyer reasonably
     prompt written notice thereof after the Seller Indemnitee becomes aware of
     such Direct Claim, stating, to the extent known, the nature of such claim
     in reasonable detail and indicating the estimated amount, if practicable,
     but in any event such notice shall not be given later than forty-five (45)
     calendar days after the Seller Indemnitee becomes aware of such Direct
     Claim, provided, that the failure to give such notice within such time
     period shall not relieve the Seller or DQE of any liability except to the
     extent the Seller or the Buyer is prejudiced by such failure, and the Buyer
     shall have a period of thirty (30) calendar days from receipt of such
     notice within which to respond to such Direct Claim. If the Buyer does not
     respond within such thirty (30) calendar day period, the Buyer shall be
     deemed to have accepted, and shall be liable for, such claim. If the Buyer
     rejects such claim, the Seller Indemnitee will be free to seek enforcement
     of its right to indemnification under this Agreement.

               (d) If the amount of any Buyer Indemnifiable Loss or Seller
Indemnifiable Loss, as the case may be, at any time subsequent to the making of
an indemnity payment in respect thereof, is reduced by recovery, settlement or
otherwise under or pursuant to any insurance coverage, or pursuant to any claim,
recovery, settlement or payment by, from or against any other entity, the amount
of such reduction, less any costs, expenses or premiums incurred in connection
therewith (together with interest thereon from the date of payment thereof at
the publicly announced prime rate then in effect of The Chase Manhattan Bank)
shall promptly be repaid by the Buyer Indemnitee to the Seller and DQE or by the
Seller Indemnitee to the Buyer, as the case may be.

               (e) With respect to those pending litigation matters set forth in
Schedule 3.7 of the Seller Disclosure Schedule (each a "Pending Litigation
Matter"), the parties agree as follows: DQE and/or the Seller will defend,
continue to defend or assume the defense of each Pending Litigation Matter on
and after the Closing Date (each such defense, an "Assumed Defense"). The Buyer
agrees to cooperate, and to cause its Subsidiaries, officers, directors and
employees to cooperate, fully in connection with such Pending Litigation
Matters, including, but not limited to, providing access to personnel and
records. The Seller or DQE shall reimburse the Buyer, and its Subsidiaries for
any out of pocket expenses (e.g. travel, lodging, meals and related expenses)
incurred by them in cooperation with the Seller or DQE as contemplated by this
Section 9.4(e); provided, however, that the Seller and DQE shall not reimburse
the Buyer or its Subsidiaries, and the Buyer and its Subsidiaries shall not be
entitled to reimbursement, for any portion of the wages, salary, benefits,
overhead or other costs, attributable to the officers, directors and employees
of the Buyer or its Subsidiaries whose cooperation may be required by this
Section 9.4(e). Notwithstanding any other provision of this Agreement to the
contrary and for the avoidance of doubt, (i) the defense of any Pending
Litigation Matter, shall not be the responsibility of the Buyer on and after the
Closing Date, except for the obligations in respect thereof set forth in this
Section 9.4(e) and (ii) the obligations set forth in this Section 9.4(e) in no
way limit or reduce the Seller's and DQE's indemnity obligation, in respect of
any Pending Litigation Matter or otherwise.

          Section 9.5 Certain Covenants in Respect of Excluded Assets. The
parties agree that the Seller may deliver such notices to such persons as it
deems advisable in respect of the assignment and transfer of the Excluded Assets
(such persons to whom such notice is delivered, "Notified Persons" and such
Excluded Assets in respect of which such notices are delivered, "Covered
Excluded Assets"); provided, however, that any such notices must (i) include the
name and contact information of the transferee or assignee and (ii) be sent to
Notified Persons by Certified U.S. mail. The Seller shall provide the Buyer with
a list of Notified Persons and Covered Excluded Assets, which list may be
updated from time to time to reflect additional notices delivered. For a period
of five years from the Closing Date, the Buyer shall, and shall cause the
Company to, deliver to the Seller and DQE, in such a manner so as not to
prejudice the Seller or DQE, notices of any claims received by the Buyer or the
Company and brought by the Notified Persons in respect of the Covered Excluded
Assets; provided, however, that the Seller or DQE shall bear the burden of proof
in respect of any such prejudice.

<PAGE>

          Section 10.1 Survival of Obligations. The representations and
warranties of the parties contained in this Agreement shall survive the Closing
until the second (2nd) anniversary of the Closing Date. None of the covenants,
obligations or agreements of the parties contained in this Agreement or in any
instrument, certificate, opinion or other writing provided for herein, shall
survive the Closing of this transaction; provided, however, that,
notwithstanding the foregoing, the covenants of DQE, the Seller and the Buyer,
as applicable, contained in Sections 1.1, 1.2, 1.3, 1.4, 1.5, 6.4, 6.5, 6.6,
6.7, 6.8, 6.9, 6.10, 6.11, 6.12, 6.14, 6.15, 6.16, 6.17, 6.18 and 6.19, the last
sentence of Section 6.1 and all of Articles II, V, IX and X shall survive the
Closing of this transaction.

          Section 10.2 Amendment and Modification. This Agreement may be
amended, modified and supplemented in any and all respects, but only by a
written instrument signed by all of the parties to this Agreement expressly
stating that such instrument is intended to amend, modify or supplement this
Agreement.

          Section 10.3 Extension; Waiver. Any failure of any of the parties to
comply with any obligation, covenant, agreement or condition herein, and any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto, and any time for the performance of any of
the obligations or other acts of a party hereto, may be waived or extended, as
the case may be, but only pursuant to a written instrument signed by all parties
entitled to the benefits thereof; provided, however, that any such waiver or
extension of such obligation, covenant, agreement or condition, or inaccuracy,
shall not operate as a waiver of, or estoppel with respect to, any subsequent
failure to comply therewith. The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

          Section 10.4 Expenses. Unless otherwise provided in this Agreement,
all costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such
expenses.

          Section 10.5 Notices. All notices and other communications hereunder

closest to expressing the intention of the invalid or unenforceable term or
provision.

result of a change in control of the Seller, a consolidation of the Seller with
or into another entity, a sale of all or substantially all of the assets of the
Seller, or a merger of the Seller with or into another entity, in any case
whether or not the Seller is the surviving entity.
