Item 5. Other Events. On July 29, 2002, we entered into a purchase agreement with DQE, Inc. ("DQE") and AquaSource, Inc. ("AquaSource") pursuant to which we agreed to acquire three operating water and wastewater first tier subsidiaries of AquaSource, a subsidiary of DQE, and assume selected, integrated operating and maintenance contracts and related assets. The purchase agreement provides for a target cash purchase price of approximately $205 million. The final purchase price may be increased by up to $10 million or decreased by up to $25 million as various purchase price adjustments are applied. These adjustments include the achievement of certain specific operating performance metrics, involving revenue, rate base and projected customer connections. We are purchasing the owned operating utilities, including assets and franchises that serve approximately 130,000 water and wastewater customer accounts in 12 states, and selected water and wastewater operating contracts that serve approximately 40,000 customers in 7 states. Over 80% of the customers in the businesses we are purchasing are located in Texas, Florida, Virginia and Indiana. Within 45 days of the agreement, AquaSource has the option to sell the operations in several states whose operations represent approximately 6% of the total customers of the businesses we are purchasing, in one or more separate transactions, with a consequent reduction in the target purchase price. The acquisition is subject to certain regulatory approvals, but does not require DQE or PSC shareholder approval. We do not expect to obtain the requisite regulatory approvals before the second half of 2003. It is our intention to fund the acquisition at closing with cash from a combination of short-term debt, long-term debt, the issuance of our common stock and/or an instrument convertible into our common stock. The ultimate decision regarding the funding of the acquisition will be based upon market conditions existing at the time the acquisition is consummated.

SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

PURCHASE AGREEMENT This Purchase Agreement, dated as of July 29, 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 Philadelphia Suburban Corporation, a Pennsylvania corporation ("PSC"), and Aqua Acquisition Corporation, a Pennsylvania corporation ("Acquisition" and, together with PSC, the "Buyer"), on the other hand (each of the Seller, DQE, PSC and Acquisition, a "Party", and collectively, the "Parties"). WHEREAS, the Seller owns all of the issued and outstanding shares of common stock (the "Utility Shares") of AquaSource Utility, Inc., a Texas corporation ("Utility") and 90 of the 100 outstanding shares of preferred stock of Utility (the "Utility Preferred Shares"); and WHEREAS, the Seller owns all of the issued and outstanding shares of common stock (the "Development Shares") of AquaSource Development Company, a Texas corporation ("Development"); and WHEREAS, the Seller owns all of the issued and outstanding shares of common stock (the "Reynolds Shares") of The Reynolds Group, Inc., an Indiana corporation ("Reynolds"); and WHEREAS, the Seller owns, directly or indirectly, all of the Integrated Assets (as defined in Section 1.1) which are not held by Utility, Development or Reynolds but are integrated with the business and/or operations of Utility, Development or Reynolds; and WHEREAS, each of the Boards of Directors of PSC, Acquisition, DQE and the Seller has approved, and deems it advisable and in the best interests of its respective shareholders to consummate, the acquisition by PSC of Utility, Development, Reynolds and by Acquisition of the Integrated Assets, which acquisition is to be effected by the purchase of (i) the Utility Shares, the Utility Preferred Shares, the Development Shares and the Reynolds Shares (collectively, the "Shares") by PSC and (ii) all of the Integrated Assets by Acquisition 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: 1

ARTICLE I PURCHASE AND SALE OF SHARES AND INTEGRATED ASSETS Section 1.1 Sale and Transfer of Shares and Integrated Assets. (a) Subject to the terms and conditions of this Agreement, on the Closing Date (as defined in Section 2.1), (i) the Seller agrees to sell, convey, assign, transfer and deliver to PSC (or to such Buyer Subsidiary (as defined in Section 5.1) as PSC may designate in writing within forty-five (45) calendar days of the date hereof), and PSC agrees to purchase and accept (or cause such Buyer Subsidiary to purchase and accept) from the Seller, all of the Seller's rights, title and interest in and to the Shares, (ii) the Seller agrees to sell, convey, assign, transfer and deliver, or cause to be sold, conveyed, assigned, transferred and delivered, to Acquisition (or to such other Buyer Subsidiary as PSC may designate in writing within forty-five (45) calendar days of the date hereof), and Acquisition agrees to purchase and accept (or PSC agrees to cause such other Buyer Subsidiary to purchase and accept) from the Seller, or one or more Subsidiaries (as defined in Section 3.2) of the Seller, all of the Seller's, and any Subsidiary of the Seller's, rights, title and interest in and to the Integrated Assets, and (iii) except as otherwise provided in this Agreement, Acquisition agrees to assume and discharge (or PSC agrees to cause any other Buyer Subsidiary that purchases the Integrated Assets to assume and discharge) when due, without recourse to the Seller or any Subsidiary of the Seller, in accordance with the respective terms and subject to the respective conditions thereof, all of the Integrated Liabilities (as defined below). (b) The "Integrated Assets" shall mean all of those assets set forth in Section 1.1 of the Seller Disclosure Schedule (as defined in Section 3.1). (c) The "Integrated Liabilities" shall mean (i) all of the performance obligations of the Seller and any Subsidiary of the Seller which relate to the Contracts included among the Integrated Assets, and (ii) all of the liabilities of the Seller and any Subsidiary of the Seller, direct or indirect, known or unknown, absolute or contingent, which relate to the Contracts included among the Integrated Assets and which arise on or after the Closing Date (as defined in Section 2.1). Section 1.2 The Purchase Price. (a) Subject to the terms and conditions of this Agreement, on the Closing Date, in consideration of (i) the aforesaid sale, conveyance, assignment, transfer and delivery to PSC (or such Buyer Subsidiary as PSC may designate pursuant to Section 1.1) of the Shares, and (ii) the aforesaid sale, conveyance, assignment, transfer and delivery to Acquisition (or such other Buyer Subsidiary as PSC may designate pursuant to Section 1.1) of the Integrated 2

Assets and Integrated Liabilities, PSC shall pay to the Seller an amount of cash equal to Two Hundred Five Million Dollars ($205,000,000) (subject to any adjustments to the Purchase Price contemplated by this Article I, the "Purchase Price"). (b) Subject to the terms and conditions of this Agreement, the Purchase Price shall be determined as of Closing Date in accordance with the following steps, subject to additional adjustment, post-Closing, pursuant to the post-Closing procedures that are specifically contained in this Article I: (i) start with the Base Purchase Price, derived as follows: the "Base Purchase Price" shall mean the amount of $205,000,000, subject to reduction to the extent that any of the Excludable Operations (as defined in Section 1.3) are excluded from the transaction in accordance with the provisions of Section 1.3; (ii) adjust the Base Purchase Price in the manner contemplated by Section 1.4 and Exhibit 1.4, subject to all limitations on any such adjustments contained in Section 1.4 and Exhibit 1.4, and subject to any adjustments to the Target Amounts (as defined in Section 1.3) contemplated by Section 1.3, to determine the Adjusted Purchase Price (the "Adjusted Purchase Price"); and (iii) further adjust the resulting Adjusted Purchase Price by the Working Capital Adjustment (as defined in Section 1.5), as contemplated by Section 1.5, subject to all limitations on any such adjustments contained in that Section 1.5 to determine the Final Purchase Price (the "Final Purchase Price"). Section 1.3 Excludable Operations. In accordance with the following procedure, the Base Purchase Price shall be reduced, as applicable. (a) The parties agree that the Seller may elect, by delivering a written notice to the Buyer, no later than forty-five (45) calendar days from the date hereof, to treat any of the following assets of the Company as Excluded Assets (as defined in Section 6.3): (i) those assets of the Seller, Utility, Development, Reynolds or any Company Subsidiary associated with or related to the Company's operations in Hawaii (the "Hawaii Operations"), (ii) those assets of the Seller, Utility, Development, Reynolds or any Company Subsidiary associated with or related to the Company's operations in Connecticut and New York (the "Northeast Operations"), (iii) those assets of the Seller, Utility, Development, Reynolds or any Company Subsidiary associated with or related to the Company's operations in New Jersey (the "New Jersey Operations"), or (iv) those assets of the Seller, Utility, Development, Reynolds or any Company Subsidiary associated with or related to the Company's operations in Kentucky 3

(the "Kentucky Operations"). Following any such election, the Hawaii Operations and/or the Northeast Operations and/or the New Jersey Operations and/or the Kentucky Operations, as the case may be, shall be listed on Section 6.3 of the Seller Disclosure Schedule and shall be treated, for all purposes under this Agreement, as Excluded Assets. (b) As used in this Agreement, the term "Excludable Operations" means the Hawaii Operations, the Northeast Operations, the New Jersey Operations and the Kentucky Operations. The Seller's election to treat any one or more of the above referenced Excludable Operations as Excluded Assets will result in a reduction to the Base Purchase Price equal to such amounts for such Excludable Operations as PSC and the Seller may mutually agree. (c) In the event that the Seller elects to treat one or more of the above-referenced Excludable Operations as Excluded Assets, then each of the target amounts that are taken into consideration in determining the Adjusted Purchase Price as contemplated by Section 1.4 (collectively, the "Target Amounts"), including those in respect of Customer Connections (as defined in Exhibit 1.4), Rate Base (as defined in Exhibit 1.4), ConOps Revenue (as defined in Exhibit 1.4), and Rate Initiatives (as defined in Exhibit 1.4), shall be reduced to the extent of and so as to reflect the effects of any election made by the Seller to treat any of the Excluded Operations as Excluded Assets pursuant to Section 1.3, as contemplated by Schedules 1.4(a), (b), (c) and (d) of Exhibit 1.4. For example, the total target Rate Base is $240,000,000 and the target Customer Connection number at October 31, 2003 is 145,615, as shown on Schedule 1.4(b) and 1.4(a) of Exhibit 1.4, respectively. In the event that the Hawaii Operations are elected by Seller to be treated as an Excluded Asset, then the targets would need to be adjusted accordingly. Specifically, based on this example, the total Rate Base target would be reduced by $6,925,000 consistent with the amount attributable to the Hawaii Operations resulting in a revised target Rate Base of $233,075,000 instead of $240,000,000. Similarly, assuming a Closing on October 31, 2003, the total Customer Connection target would be reduced by the 513 connections projected to be attributable to the Hawaii Operations as of that date resulting in a revised Customer Connection target of 145,102 instead of the total 145,615. The new target numbers (reflecting the exclusion of the Hawaii Operations) would then be used to determine the Adjusted Purchase Price as contemplated by Section 1.4. (d) In the event that a Condemnation Proceeding results in a governmental taking or settlement in lieu thereof of all or part of one or more of the Company's Investor Owned Utility (IOU) systems, then the Target Amounts shall be reduced to reflect the effects of any such governmental taking or settlement in such manner as the parties may mutually agree or such amount as is determined pursuant to this Section 1.3(d). No later than thirty (30) calendar 4

days following any such governmental taking or settlement, the Seller shall deliver to PSC the Seller's proposed adjustments to the Target Amounts as a result of such government taking or settlement. Following the delivery of such notice, if the Seller and PSC are unable to agree within thirty (30) calendar days following PSC's receipt of the Seller's proposed adjustment in respect thereof, 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 governmental taking or settlement and all adjustments to the Target Amounts proposed in respect thereof and make a final determination with respect to such adjustment within thirty (30) calendar days of such appointment. 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. Section 1.4 Purchase Price Adjustment. The Base Purchase Price (as adjusted by Section 1.3) shall be adjusted using the individual Target Amounts as described in Exhibit 1.4 to establish the Adjusted Purchase Price, provided, however, that in no event shall the sum of these Target Amounts in determining the Adjusted Purchase Price pursuant to this Section 1.4 cause the Base Purchase Price to be reduced by an amount greater than $25,000,000 or to be increased by an amount greater than $10,000,000. For the avoidance of doubt, if the cumulative adjustments resulting from this Section 1.4 would result in reducing the Base Purchase Price by an amount that is greater than $25 million, the Adjusted Purchase Price shall equal the Base Purchase Price less $25 million; and if the cumulative adjustments contemplated by this Section 1.4 would result in increasing the Base Purchase Price by an amount that is greater than $10 million, then the Adjusted Purchase Price shall equal the Base Purchase Price plus $10 million. In addition, the Parties recognize and agree that the Working Capital Adjustment contemplated by Section 1.5 is separate and apart from the adjustments contemplated by this Section 1.4 and, as such, is neither increased nor decreased or affected in any way by the limitations on adjustments contained in this Section 1.4 (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 Adjusted Purchase Price, if any (the "Estimated Adjusted Purchase Price") showing the individual and cumulative effect of all adjustments contemplated by this Section 1.4 for Buyer's review and comment. At the Closing, the Purchase Price shall be adjusted to reflect the Estimated Adjusted Purchase Price, subject to further adjustment post-Closing as contemplated by Section 1.4(b). (b) Within thirty (30) calendar days following the Closing Date (or if on the Closing Date the Company shall not yet have received a Final Order approving the Planned Rate Initiative (as defined in Exhibit 1.4) that is not 5

yet filed on the date of this Agreement and that is budgeted to exceed 10% of the Target Amount for Rate Initiatives, then within thirty (30) calendar days following the date that such Final Order is received but in no event later than April 10, 2004), the Seller shall prepare and deliver to the Buyer in good faith a Final Closing Statement setting forth the Adjusted Purchase Price as finally determined by the Seller in accordance with this Section 1.4 (the "Final Closing Statement"). For purposes of the Final Closing Statement, the Planned Rate Initiative that is not yet filed on the date of this Agreement and that is budgeted to exceed 10% of the Target Amount for Rate Initiatives that has received a Final Order after the Closing Date but prior to March 30, 2004 (a "Post-Closing Rate Initiative") shall be treated for purposes of determining "Adjustment #4 regarding Rate Initiatives" as contemplated on Exhibit 1.4 as if such Planned Rate Initiative had occurred prior to Closing. Within fifteen (15) calendar days following the Buyer's receipt of the Final Closing Statement, the Buyer may object in good faith to the Adjusted Purchase Price 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 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 determine the Adjusted Purchase Price within thirty (30) calendar days of such appointment. 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. Upon determination by agreement of the Seller and the Buyer or by binding determination of said accounting firm of the Adjusted Purchase Price, (i) if the Adjusted Purchase Price exceeds the Estimated Adjusted Purchase Price (such excess amount, the "Deficiency"), the Buyer shall pay to the Seller the Deficiency, or (ii) if the Estimated Adjusted Purchase Price exceeds the Adjusted Purchase Price (such excess amount, the "Excess"), the Seller shall pay to the Buyer the Excess. Any portion of any Deficiency or Excess owed hereunder shall be paid to the Party or Parties owed the same by the Party or Parties owing the same by wire transfer in immediately available funds to an account designated by the Party or Parties 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 Adjusted Purchase Price, and such excess or deficiency payment shall be accompanied by an additional payment of interest, calculated with a 4% annual interest rate from the date of Closing to the date of payment under this provision (except that any amount payable resulting from the Post-Closing Rate Initiative shall be disregarded for purposes of calculating such interest payment). Section 1.5 Working Capital Adjustment. The Adjusted Purchase Price shall be adjusted to determine the Final Purchase Price, as contemplated by this 6

Section 1.5, provided, however, that in no event, shall the increase in the Adjusted Purchase Price resulting from any adjustment contemplated by this Section 1.5 exceed the amount of $10,000,000, and provided, further, that for the purposes of calculating current assets as contemplated by Section 1.5(a), the Company's unbilled revenues entitled to be considered in any such calculation shall not exceed the amount of $3,000,000. Notwithstanding the foregoing, the Buyer shall waive the foregoing cap on unbilled revenues if, and to the extent that, the Seller has been impacted by documented billing delays that have prohibited certain unbilled revenues from being billed to customers in a timely fashion consistent with past practice. (a) The Adjusted Purchase Price shall be adjusted by an amount of dollars, positive or negative, as the case may be, equal to the net amount of (i) the aggregate amount of the current liabilities of the Company (incurred in the ordinary course of business consistent with past practice), including, but not limited to, accounts payable owed by the Company to any unaffiliated third party as of the Closing Date, excluding any accrued Taxes that are to be paid by the Seller pursuant to this Agreement, and (ii) the aggregate amount of current assets of the Company (incurred in the ordinary course of business consistent with past practice), including, but not limited to, accounts receivable owed by any unaffiliated third party as of the Closing Date, but excluding any monies held in escrow pursuant to Section 7.16 (such net amount, the "Working Capital Adjustment"). 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 Working Capital Adjustment, if any (the "Estimated Working Capital Adjustment") showing the individual and cumulative effect of all adjustments contemplated by this Section 1.5 for Buyer's review and comment. At the Closing, the Adjusted Purchase Price shall be adjusted to reflect the Estimated Working Capital Adjustment, subject to further adjustment post-Closing as contemplated by Section 1.5(b). (b) Within thirty (30) 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 Working Capital Adjustment in accordance with this Section (the "Final Working Capital Closing Statement").

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 IV shall in no event exceed an aggregate amount of dollars equal to the Indemnity Cap (as defined in Section 4.3(b)); provided, however, that in determining whether the Seller's and DQE's liability for a particular Buyer Indemnifiable Loss or the Buyer's liability for a particular Seller Indemnifiable Loss, in either case, pursuant to this Article IV is limited by the Indemnity Cap, the Parties shall refer to the Indemnity Cap that is or was in effect on the date that the Buyer Indemnitee or Seller Indemnitee, as the case may be, delivered a written notice of such Buyer Indemnifiable Loss or Seller Indemnifiable Loss, as the case may be, to the Seller as contemplated by Section 4.4 hereof. (b) As used in this Agreement, (i) the term "Indemnity Basket" shall mean $250,000, and (ii) the term "Indemnity Cap" shall mean $15,000,000; provided, however, that on the first (1st) anniversary of the Closing Date, the Indemnity Cap shall be reduced to, and shall thereafter mean, $7,500,000; and provided further, that on the second (2nd) anniversary of the Closing Date, the Indemnity Cap shall be reduced to, and shall thereafter mean, zero, unless the Indemnity Period has been extended until the third (3rd) anniversary of the Closing Date, pursuant to Section 4.2(a), in which case the Indemnity Cap shall continue to mean $7,500,000 until the third (3rd) anniversary of the Closing Date, upon which it shall be reduced to, and shall thereafter mean, zero. 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 the Indemnity Cap: Buyer Indemnifiable Losses relating to (i) any litigation, existing or threatened, that is required to be set forth in Sections 3.7, 3.8(a), 3.8(b), 3.9(i) or 3.10 of the Seller Disclosure Schedule, (ii) Excluded Assets, (iii) any and all liabilities and obligations of the Seller or the Subsidiaries of the Seller (other than any liabilities or 29

obligations of the Seller (in respect of the Company), Utility, Development, Reynolds or any Company Subsidiary or any of the Integrated Assets or Integrated Liabilities), (iv) indemnity obligations of the Parties in respect of Taxes, as set forth in Section 4.5, (v) indemnity obligations of the Seller and DQE in respect of certain litigation as set forth in Section 4.6, (vi) indemnity obligations of the Seller and DQE in respect of Environmental Law, as set forth in Section 4.7, and (vii) any fraud committed by DQE, the Seller, the Company or any Company Subsidiary (provided that the foregoing reference to the Company 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 the Indemnity Cap: Seller Indemnifiable Losses relating to (i) indemnity obligations of the Parties in respect of Taxes, as set forth in Section 4.5, (ii) any breach or violation of any Environmental Law by PSC, Acquisition, any Buyer Subsidiary designated by PSC pursuant to Section 1.1, the Company or any Company Subsidiary on or after the Closing Date, and (iii) any fraud committed by PSC, Acquisition, any Buyer Subsidiary designated by PSC pursuant to Section 1.1, the Company or any Company Subsidiary (provided that the foregoing reference to the Company or any Company Subsidiary refers to fraud committed on or after the Closing Date).

(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 30

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 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 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 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. (e) Notwithstanding any other provision of this Agreement to the contrary, (i) except to the extent otherwise provided in Article IX, the rights and remedies of the Parties under this Article IV 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) 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. Section 4.4 Defense of Claims. (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 not a Party or an affiliate of a Party (a "Third Party Claim") with respect to which indemnification is to be 31

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 twenty (20) calendar days after the Buyer Indemnitee's receipt of written notice of such Third Party Claim. 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 given later than twenty (20) calendar days after the Seller Indemnitee's receipt of written notice of such Third Party Claim. 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. 32

(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 ten (10) 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 IV. (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 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 33

Indemnitee fails to consent to such firm offer within ten (10) 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 IV. (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, stating 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 twenty (20) calendar days after the Buyer Indemnitee becomes aware of such Direct Claim, 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 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, stating 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 twenty (20) calendar days after the Seller Indemnitee becomes aware of such Direct Claim, 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 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 34

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: no later than the Closing Date, DQE and/or the Seller shall identify those Pending Litigation Matters for which DQE and/or the Seller will defend, continue to defend or assume the defense of on and after the Closing Date (each such defense, an "Assumed Defense"). PSC and Acquisition agree to cooperate, and to cause their Subsidiaries, officers, directors and employees to cooperate, fully in connection therewith, including, but not limited to, providing access to personnel and records. The Seller or DQE shall reimburse PSC, Acquisition and their 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 4.4(e); provided, however, that the Seller and DQE shall not reimburse PSC, Acquisition or their Subsidiaries, and PSC, Acquisition and their 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 PSC, Acquisition or their Subsidiaries whose cooperation may be required by this Section 4.4(e). For the avoidance of doubt, (i) the defense of any Pending Litigation Matter, the defense of which is not assumed by the Seller or DQE as an Assumed Defense, shall be the responsibility of PSC or Acquisition on and after the Closing Date, subject at all times to the procedures, limitations and other obligations in respect thereof set forth in Article IV, and (ii) the obligations set forth in this Section 4.4(e) in no way limit or reduce the Seller's and DQE's indemnity obligation, in respect of any Pending Litigation Matters, whether or not any such Pending Litigation Matter has been assumed by the Seller or DQE as an Assumed Defense. Section 4.5 Tax Indemnity. 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, and PSC and Acquisition shall, jointly and severally, indemnify, defend and hold harmless each Seller Indemnitee from and against any and all of the liabilities of the Seller and DQE, and PSC and Acquisition, 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 Utility, Development or Reynolds, as the case may be, 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 transactions not in the ordinary course 35

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 is the common parent arising under Treasury Regulation section 1.1502-6 (or similar provision of state, local or foreign law). The Seller shall be entitled to all Tax refunds (including interest) attributable to the taxable periods for which it is liable; provided, that the Buyer shall elect under Treasury Regulation section 1.1502-21(b)(3)(ii) (or similar provision of state, local or foreign law) to relinquish, with respect to any net operating losses attributable to Utility, Development or Reynolds, or any Company Subsidiary, the portion of the carryback period for which any such corporation was a member of the consolidated group of which DQE is the common parent. (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 (1st) day after the Closing Date. The Buyer shall be entitled to all Tax refunds (including interest) attributable to the taxable periods for which it is liable. (c) The obligations of the Parties to indemnify each other pursuant to this Section 4.5 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 4.5, has expired. Any payment due to an indemnified Party pursuant to this Section 4.5 shall be paid promptly by the indemnifying Party upon receipt of written notice. (d) Neither 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) calendar 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 4.5 (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 36

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 4.5(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 4.5(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 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 Shares and the Integrated Assets. Section 4.6 Certain Litigation Indemnification and Related Matters. (a) 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 from and against any claims that were brought or could have been brought in (i) the litigation captioned Edward Wallace, et al. v.

(Cause No. 2001-05987), filed in the 270th Judicial District Court of Harris County, Texas (the "Class B Stock Litigation"), or any settlement or compromise relating thereto, (ii) the litigation captioned AquaSource, Inc. v. JPT Financial, Inc. and Acquisition Partners, Inc., (Cause No. 2001-31233), filed in the 270th Judicial District Court of Harris County, Texas (the "JPT Litigation"), or any settlement or compromise relating thereto, and (iii) any other claims involving the Seller's Class B Common Stock, or any settlement or compromise relating thereto. In addition, notwithstanding any other provision of this Agreement to the contrary, any right, title or interest that Utility, Development or Reynolds, or any Company Subsidiary, may have in or to any benefit resulting from or arising out 37

of the Class B Stock Litigation or the JPT Litigation, including any benefits in the nature of claims or counterclaims, payments, insurance proceeds, settlements, awards, judgments and the like, shall be deemed to be Excluded Assets and, as such, shall be assigned to the Seller as contemplated by Section 6.3 of this Agreement. (b) PSC and Acquisition acknowledge and agree that the Seller shall be entitled exclusively to control, defend, prosecute and settle the Class B Stock Litigation and the JPT Litigation and PSC and Acquisition agree that each of them will, and will cause their respective Subsidiaries (including, after the Closing Date, Utility, Development and Reynolds, and the Company Subsidiaries) and each of their Subsidiaries' officers, directors and employees, to cooperate fully in connection therewith, including, but not limited to, providing access to personnel and records. The Seller shall reimburse PSC, Acquisition and their Subsidiaries for any out-of-pocket expenses (i.e., travel, lodging, meals and related expenses) incurred by the them in cooperating with the Seller as contemplated by this Section 4.6(b), provided, however, that the Seller shall not reimburse PSC, Acquisition or their Subsidiaries, and PSC, Acquisition and their Subsidiaries shall not be entitled to reimbursement, for any portion of the wages, salary, benefits, overhead or other costs attributable to the officers, directors, employees and agents of PSC, Acquisition or their Subsidiaries whose cooperation may be required by this Section 4.6(b). Section 4.7 Certain Indemnification in Respect of Environmental Law. (a) Notwithstanding any other provision of this Agreement, the Seller and DQE shall, jointly and severally, indemnify, defend, reimburse, and hold harmless each Buyer Indemnitee from and against any and all Indemnifiable Losses arising out of or resulting from any of the following: (i) any breach of any representation or warranty made by the Seller in Section 3.11 or Section 3.19 hereof that is discovered within the Indemnity Period; (ii) any Third Party Claim (as defined in Section 4.4) asserted prior to the tenth (10th) anniversary of the Closing Date for any Pre-Closing Environmental Liability (as defined in Section 4.7(b)(ii)); and (iii) any First Party Environmental Claim (as defined in Section 4.7(b)(iv)) asserted prior to the tenth (10th) anniversary of the Closing Date for any Pre-Closing Violation or Contamination (as defined in Section 4.7(b)(i)). Any and all Indemnifiable Losses arising out of or resulting from clauses (i), (ii), or (iii) above shall not be limited by the Indemnity Cap (as defined in Section 4.3(b)), but shall be subject to the Indemnity Basket (as defined in Section 4.3(b)). (b) As used in this Agreement: (i) the term "Pre-Closing Violation or Contamination" means any and all cost and liability (other than Excepted Liabilities) 38

arising out of or related to: (A) any violation of any Environmental Laws by the Seller, Utility, Development, Reynolds, or any of the Company Subsidiaries, or any presence in the environment, Release, threat of Release or any exposure of either an individual or the environment, of or to any Hazardous Substances at or under any of the Properties (as defined in Section 4.7(b)(iii)), which, for any of the foregoing, occurred on or before or existed as of the Closing Date, and (B) any post-Closing Date liabilities arising from any such pre-Closing Date violation, presence, Release, threat of Release or exposure. (ii) the term "Pre-Closing Environmental Liability" means any and all cost and liability (other than Excepted Liabilities) arising out of or related to: (A) any presence in the environment, Release, threat of Release, or any exposure of either an individual or the environment, of or to any Hazardous Substances from, at, or under any of the Properties or otherwise arising in connection with the Company's current or former operations before the Closing Date; (B) the off-site transportation, storage, treatment, recycling, or Release of any Hazardous Substances generated or Released, before the Closing Date, by the Seller, Utility, Development, Reynolds, or any of the Company Subsidiaries, or any predecessor of such Persons; (C) any violation of any Environmental Laws by the Seller, Utility, Development, Reynolds, or any of the Company Subsidiaries at or under any of the Properties which, occurred on or before or existed as of the Closing Date; and (D) any post-Closing Date liabilities arising from any such pre-Closing Date violation or presence, Release, threat of Release or exposure.

(iv) the term "First Party Environmental Claim" means any claim, action, or proceeding, made or brought by any Buyer Indemnitee asserting either liability or the potential for liability under any Environmental Laws. (c) If, after the Closing Date, PSC, Acquisition or any Buyer Subsidiary: (i) exacerbates any Release or threatened Release of Hazardous Substances specifically disclosed by the Seller to PSC or Acquisition existing on or before the Closing Date (a "Pre-Existing Release") or (ii) exacerbates any violation by the Seller, Utility, Development, Reynolds, or any of the Company 39

Subsidiaries of any Environmental Laws that existed as of the Closing Date (a "Pre-Existing Violation"), then the obligation of the Seller and DQE for any Buyer Indemnifiable Losses in respect of any such Pre-Existing Release or Pre-Existing Violation shall be reduced to the extent that PSC, Acquisition or any Buyer Subsidiary exacerbated such Pre-Existing Release or Pre-Existing Violation. PSC, Acquisition and the Buyer Subsidiaries shall not be considered to have exacerbated a Pre-Existing Release or Pre-Existing Violation by having their employees act, in the ordinary course of business, in the same manner that any employees of the Seller, Utility, Development, Reynolds, or any of the Company Subsidiaries acted in the ordinary course of business before the Closing Date (the "Pre-Existing Actions"); provided, however, that PSC, Acquisition and the Buyer Subsidiaries shall be considered to have exacerbated a Pre-Existing Release or Pre-Existing Violation by their inaction or failure to modify any Pre-Existing Actions to the extent required to comply with any applicable Environmental Laws. (d) Notwithstanding any other provision of this Agreement to the contrary, nothing in this Agreement is intended to restrict PSC, Acquisition or any Buyer Subsidiary from fulfilling its or their obligations to take appropriate actions as may be required by applicable Environmental Laws. (e) The right of any Buyer Indemnitee to indemnification under this Section 4.7 shall be in addition to, and not in lieu of, any statutory rights which such Buyer Indemnitee has or may obtain under Environmental Laws. (f) For the avoidance of doubt, the Parties agree that the provisions of Section 4.3(d), Section 4.3(e), and all of Section 4.4 shall apply to the indemnity obligations set forth in this Section 4.7, provided, however, that for purposes of applying such provisions to this Section 4.7, (i) all references to the Indemnity Cap contained in such provisions shall be disregarded, and (ii) all references to Direct Claims shall be read to include First Party Environmental Claims.

The Seller and the Buyer shall, as soon as practicable after the date hereof, file or cause to be filed with the Federal Trade Commission and the Department of Justice any notifications required to be filed under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the rules and regulations promulgated thereunder with respect to the transactions contemplated hereby. The Seller and the Buyer will use all commercially reasonable efforts to respond on a timely basis to any requests for additional information made by either of such agencies. (b) Other Regulatory Approvals.

To the extent any such applications, notices, petitions, filings or other documents require an allocation of the Purchase Price among the assets of the Company, the Seller and the Buyer shall make any such allocation in a manner that is consistent with any allocations made pursuant to Section 7.9 hereof. The Buyer shall be precluded from including in any application for regulatory approval contingencies relating to rate treatment of acquisition premiums. Section 7.3 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. Section 7.4 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 the Seller, Utility, Development and Reynolds, and each Company Subsidiary, (each, a "Company Indemnified Party" and, collectively, the "Company 51

Indemnified Parties") with respect to their activities as such prior to or on the Closing Date, as provided in the Seller's, Utility's, Development's and Reynolds', and each Company Subsidiary's, respective articles of incorporation, by-laws, other organizational documents or indemnification agreements 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 and provided further that, the Buyer's or any Buyer Subsidiary's indemnity obligation for a particular claim hereunder shall be reduced in respect of any Company Indemnified Party asserting such claim to the extent of any insurance proceeds actually received by such Company Indemnified Party in respect of such claim. (b) Successors. In the event that after the Closing Date, Utility, Development or Reynolds, or any of their 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 Utility, Development or Reynolds, as the case may be, shall assume the respective obligations of Utility, Development or Reynolds, as the case may be, set forth in this Section 7.4. (c) Insurance for Pre-Closing Period. 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 (in respect of the Company), Utility, Development or Reynolds immediately prior to the Closing in respect of pre-Closing acts or omissions on terms no less favorable than the terms of any such current insurance coverage. (d) Benefit. The provisions of this Section 7.4 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 7.5 Public Announcements. The Buyer and the Seller shall consult with each other before issuing any press release with respect to this Agreement and the transactions contemplated hereby and shall not issue any such press release or make any such written public statement without the prior written consent of the other Party, which shall not be unreasonably withheld, delayed or conditioned, provided, however, that a Party may, without the prior written consent of the other Party, issue such press release or make such written public 52

statement as the Party may determine, in good faith after consultation with counsel, is required by law or by obligations pursuant to any listing agreement with or rules of any national securities exchange, if it has used all commercially reasonable efforts to consult with the other Party. Section 7.6 Workforce Matters. (a) Neither Utility, Development, Reynolds nor any Company Subsidiary has any employees. The Buyer will make offers of employment, effective as of the Closing, to those employees of the Seller identified by mutual written agreement of the Seller and PSC as Affected Employees (such individuals, the "Affected Employees") such that such Affected Employees do not suffer an "employment loss" under the WARN Act (as defined below) as a result of such offers. The Buyer and the Seller acknowledge that if the Buyer makes appropriate offers to all Affected Employees, none of such Affected Employees will suffer an "employment loss" as defined under the WARN Act. As used in this Agreement, the term "WARN Act" shall mean the Worker Adjustment and Retraining Notification Act. 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. If any Affected Employee is not hired by the Buyer as of the Closing or if the Buyer or any Affected Employee terminates such Affected Employee's employment as of or after the Closing, then the Buyer shall be responsible for any and all severance costs for all such Affected Employees, including payments owing under those agreements, plans or arrangements listed in Section 3.9(a) of the Seller Disclosure Schedule. 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 on account of any termination of such Affected Employee's employment on or after the Closing Date. Neither Buyer nor its affiliates shall be responsible for providing severance benefits to any employee of Seller or its affiliates other than benefits payable in respect of Affected Employees in accordance with this Section 7.6(a). 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) before, on or after the Closing Date. 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 the Seller with 53

respect to the Affected Employees prior to 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 with respect to the Affected Employees on and after the Closing Date. 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. (b) The Buyer expressly agrees that without the Seller's consent, (i) from the date hereof until the first (1st) anniversary of the Closing Date, it will not directly solicit for employment or employ any employees of the Seller who are not Affected Employees, and (ii) from the Closing Date until the first (1st) anniversary of the Closing Date, it will cause the Company and the Company Subsidiaries and any Buyer Subsidiaries not to directly solicit for employment or employ any employees of the Seller who are not Affected Employees; provided that nothing herein shall prohibit the Buyer or any of its affiliates from placing advertisements for employment. The Seller expressly agrees that without PSC's consent, (i) from the date hereof until the first (1st) anniversary of the Closing Date, it will not directly solicit for employment any of the Affected Employees or employ after the Closing Date any of the Affected Employees actually hired by the Buyer, and (ii) from the Closing Date until the first anniversary of the Closing Date, it will cause its affiliates to not, and require in any agreement entered into for the sale of any of its operations that any purchaser of such operations will not, directly solicit for employment any of the Affected Employees or employ after the Closing Date any of the Affected Employees actually hired by the Buyer; provided that nothing herein shall prohibit the Seller or any of its affiliates or any purchaser of the Seller's operations from placing advertisements for employment. Section 7.7 Employee Benefit Plans. (a) Continued Employment; Service Credit. Except as otherwise provided herein, the Buyer shall not assume any Company Plan, nor shall there be any transfer of assets or liabilities of any Company Plan to any plan, program or arrangement maintained by the Buyer or any of its affiliates. If any Affected Employee becomes a participant in any employee benefit plan, practice or policy of the Buyer or any of its affiliates, 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 Company Plan, and all service with the Buyer or any of its affiliates on and after the Closing Date 54

but prior to the time such employee becomes such a participant, for purposes of determining eligibility and vesting and for purposes of severance and vacation. 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. (b) Continuation of Agreements. Section 7.7(b) of the Seller Disclosure Schedule lists all contracts, agreements and commitments of the Seller, Utility, Development or Reynolds, or any Company Subsidiary in effect as of the date hereof that apply to any Affected Employee (each, a "Section 7.7(b) Agreement"). The Buyer shall, and shall cause Utility, Development and Reynolds, and each Company Subsidiary, to assume and honor each Section 7.7(b) Agreement in accordance with its terms; provided, however, that this undertaking is not intended to prevent the Seller, Utility, Development or Reynolds, or any Company Subsidiary, from enforcing a Section 7.7(b) Agreement in accordance with its terms, including, without limitation, any reserved right to amend, modify, suspend, revoke or terminate the Section 7.7(b) Agreement or portion thereof. Section 7.8 Tax Treatment. (a) Neither the Seller nor the Buyer shall make or file any election under Section 338 of the Code or any corresponding provision of state or local Tax law with respect to the purchase of the Shares and for the stock of each Company Subsidiary pursuant to this Agreement. (b) Utility, Development and Reynolds will each elect under Section 168(k)(2)(C)(iii) of the Code not to deduct additional first (1st) year depreciation for any water utility property placed in service during taxable years that include any period from September 11, 2001 through the Closing Date. Section 7.9 Allocation of Consideration. (a) The consideration attributable to the purchase of the Shares and the Integrated Assets shall be allocated among the Shares and the Integrated Assets as set forth in Exhibit 7.9 hereto, in compliance with Section 1060 of the Code and the regulations promulgated thereunder. Within thirty (30) calendar days after the determination of the adjustments pursuant to Article I, the Seller shall deliver to the Buyer a schedule (the "Adjustment Schedule") allocating said adjustments among the Shares and the Integrated Assets. (b) The Buyer may dispute any allocation set forth on the Adjustment Schedule; provided, however, that (i) the Buyer shall not dispute any of the 55

original allocations set forth in Exhibit 7.9 and (ii) the Buyer shall notify the Seller in writing (the "Allocation Dispute Notice") of each disputed item, specifying the allocation in dispute and setting forth, in reasonable detail, the basis for such dispute within thirty (30) calendar days of the Buyer's receipt of the Adjustment Schedule. The Buyer shall submit only one Allocation Dispute Notice containing all disputed allocations. In the event of such a dispute, the Buyer and the Seller shall attempt to reconcile their differences and any resolution by them as to any disputed allocations shall be final, binding and conclusive. If the Buyer and the Seller are unable to reach a resolution with such effect within thirty (30) calendar days of the receipt by the Seller of the Allocation Dispute Notice, the Buyer and the Seller shall submit the items remaining in dispute for resolution to a nationally recognized accounting firm, mutually acceptable to both the Seller and PSC, which shall, within thirty (30) calendar days after submission, determine and report to the Parties upon such remaining disputed allocations, and such report shall be final, binding and conclusive on the Parties hereto. All costs and expenses of the nationally recognized accounting firm relating to the disputed allocations shall be borne equally by the Buyer and the Seller. (c) Upon agreement of the Parties with respect to the Adjustment Schedule, or the completion of a report prepared by a nationally recognized accounting firm pursuant to Section 7.9(b), a schedule (the "Final Allocation Schedule") setting forth the allocation among the Shares and the Integrated Assets as specified in Section 7.9(a) and modified pursuant to Section 7.9(b) shall be prepared by the Parties. Each of the Buyer and the Seller shall (i) timely file with each relevant Tax authority all forms and Tax Returns required to be filed in connection with the allocation set forth in the Final Allocation Schedule (including Internal Revenue Service Form 8594), (ii) be bound by such allocation for purposes of determining Taxes, (iii) prepare and file, and cause their respective affiliates to prepare and file, their Tax Returns on a basis consistent with such allocation, and (iv) not take any position, or cause their respective affiliates to take any position, inconsistent with such allocation on any Tax Return, in any audit or proceeding before any Tax authority or in any report made for Tax purposes; provided, however, that, notwithstanding anything in this Section 7.9 to the contrary, the Parties shall be permitted to take a position inconsistent with that set forth in this Section 7.9 if required to do so by a final and unappealable decision, judgment, decree or other order by any court of competent jurisdiction. In the event that any of such allocations are disputed by any Tax authority, the Seller or the Buyer, as the case may be, receiving notice of the dispute shall promptly notify the Seller or the Buyer, as the case may be, not receiving notice of the dispute. Section 7.10 Tax Returns. 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 all or any portion of the Company for taxable years or periods 56

The Seller and PSC 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 all or any portion of the Company. Section 7.11 Transfer Taxes. Notwithstanding any other provision of this Agreement to the contrary, the Buyer and the Seller shall bear equally (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. The Seller shall execute and deliver to PSC, and PSC 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 7.12 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, 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.

Section 7.13 Transition Services. Within one hundred eighty (180) calendar days of the date hereof, the Parties shall use all commercially reasonable 57

effects to enter into one or more definitive agreements pursuant to which DQE or the Seller shall provide to the Buyer, for a period of six months following the Closing Date, any or all services previously provided by DQE or the Seller, respectively, to the Company prior to the Closing Date including, but not limited to: (i) accounting services (specifically the Lawson System), (ii) information technology services, (iii) data processing services, and (iv) such other services and products as shall be mutually agreed to by the Parties, in each case to the extent that DQE or the Seller is able to provide such services without any undue hardship on DQE or the Seller and in all cases at a price for any such services that is equal to DQE's or the Seller's actual cost for such services, as the case may be, to be paid on a monthly basis by the Buyer to DQE or the Seller. Section 7.14 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 to correct any matter that would otherwise constitute a breach of any representation, warranty or covenant contained herein. If the Seller Disclosure Schedule is updated pursuant to this provision so as to disclose additional liabilities or obligations of the Company that, in the aggregate, exceed $15,000,000 (except for those liabilities or obligations resulting from (i) any change in law, rule or regulation of any Governmental Authority that applies generally to similarly situated Persons, (ii) general changes in the industries in which the Company operates its assets or conducts its business, and (iii) a Permitted Financial Impact), then the Buyer shall have the right to terminate this Agreement pursuant to Section 9.1(f). Notwithstanding any other provision hereof to the contrary, the Seller Disclosure Schedule and the representations and warranties made by the Seller 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.
