(b) In connection with such repayment, the Company and ENBW shall, simultaneously upon receipt of such repayment or assumption, execute and deliver such documentation evidencing the repayment and cancellation of indebtedness as Buyer shall reasonably request.

2.5 Post-Closing Balance Sheet Amount.

(a) Promptly following the Closing, Buyer will prepare a Post-Closing Balance Sheet and shall calculate the amount by which the Balance Sheet Adjustment Amount reflected on such Post-Closing Balance Sheet is less or more than the Balance Sheet Adjustment Amount reflected on the Closing Date Balance Sheet (such excess or deficiency, as finally determined pursuant to this Section 2.5, the “Post-Closing Balance Sheet Adjustment Amount”). Buyer shall deliver to the Company and the Asset Sellers, within 45 days following the Closing Date, its Post-Closing Balance Sheet and calculation of the Post-Closing Balance Sheet Adjustment Amount, together with reasonable detail showing the calculations made by the Buyer in determining such Post-Closing Balance Sheet Adjustment Amount. If the Company or any of the Asset Sellers disagree with the Post-Closing Balance Sheet and Buyer’s calculated Post-Closing Balance Sheet Adjustment Amount, such party may, within 14 days after delivery of such Post-Closing Balance Sheet and Post-Closing Balance Sheet Adjustment Amount, deliver a notice to Buyer setting forth the nature of the disagreement and the proposed revisions to such Post-Closing Balance Sheet Adjustment Amount.

(b) If a notice of disagreement shall be duly delivered pursuant to Section 2.5(a) or Section 11.19, the Company and the Asset Sellers and Buyer shall, during the 14 days following such delivery, use their commercially reasonable efforts to reach agreement on the disputed items or amounts. If, during such period, the Company and the Asset Sellers and Buyer are unable to reach such agreement, they shall promptly thereafter cause a nationally reorganized public accounting firm mutually agreeable to them (the “Accounting Referee”) to review the disputed items or amounts (it being understood that in making such determinations, the Accounting Referee shall be functioning as an expert and not as an arbitrator). In making such determinations, the Accounting Referee shall consider only those items or amounts to which the Company and the Asset Sellers have disagreed. The Accounting Referee shall deliver

-16-

to Buyer and the Company and the Asset Sellers, as promptly as practicable (but in any case no later than 30 days from the date of engagement of the Accounting Referee), a report setting forth its determination on the disputed item or amount. Such report shall be final and binding upon Buyer and the Company and the Asset Sellers. The cost of such review and report incurred by the Accounting Referee shall be borne by the party for which such determination goes against.

(c) If the Balance Sheet Adjustment Amount reflected on the Post-Closing Balance Sheet is more than the Balance Sheet Adjustment Amount reflected on the Closing Date Balance Sheet, the Company and the Asset Sellers shall pay the amount of such excess to Buyer, by wire transfer to a bank account of Buyer in accordance with wire transfer instructions delivered by Buyer to the Company and the Asset Sellers no later than 10 business days following delivery of the Post-Closing Balance Sheet Adjustment Amount or final determination of any dispute pursuant to Section 2.5(b), as applicable. Alternatively, Buyer may, at its option, set off any such excess against any payment due and owing by Buyer to Asset Sellers pursuant to this Agreement in accordance with the provisions of Section 13.6 hereto. If the Balance Sheet Adjustment Amount reflected on the Post-Closing Balance Sheet (i) is less than the Balance Sheet Adjustment Amount reflected on the Closing Date Balance Sheet and/or (ii) indicates that the current assets of the LLC exceed the current liabilities and long-term liabilities (including any Outstanding Loan Amounts but excluding the Disclosed Loan Amounts) of the LLC, Buyer shall pay the amount of such difference in clause (i) and such excess, if any, in clause (ii) to the Company and ENBW (in the same proportions as the payments made pursuant to Section 2.3(a)) by wire transfer to the bank accounts of the Company and ENBW in accordance with wire transfer instructions delivered by Company and ENBW to Buyer, no later than five (5) business days following delivery of the calculation of the Post-Closing Balance Sheet Adjustment Amount.

2.6 Allocation of Consideration. The parties hereto intend that the purchase be treated as a taxable transaction for U.S. federal and state income tax purposes. Buyer shall provide a draft allocation statement to the Company and the Asset Sellers within 15 days of the date hereof and Buyer and the Company and the Asset Sellers shall negotiate in good faith and determine the allocation of the Purchase Price plus any Assumed Liabilities among the Membership Interests and the Acquired Assets prior to the Closing Date (the “Allocation”); provided that failure to agree on such Allocation shall not be a condition to Closing. The agreed upon Allocation, if any, shall be conclusive and binding upon Buyer and the Company and the Asset Sellers for all purposes, and the parties agree that all returns and reports (including IRS Form 8594) and all financial statements shall be prepared in a manner consistent with (and the parties shall not otherwise file a Tax Return position inconsistent with) such Allocation unless required by the IRS or any other applicable taxing authority.

2.7 Transfer Taxes; Withholding Taxes. The Asset Sellers and the Company, on the one hand, and Buyer, on the other hand, will each pay one half of any sales, use, value-added, stamp duty, excise or similar transfer taxes (“Transfer Taxes”) imposed or levied by reason of the sale and transfer of the Acquired Assets and the Membership Interests pursuant to this Agreement. For the avoidance of doubt, any withholding Taxes required to be paid or withheld

-17-

in connection with the payment of the Acquired Assets Payments or the Contingent Payments are not Transfer Taxes. The parties will cooperate with each other to the extent reasonably requested and legally permitted to minimize any such Transfer Taxes. All payments contemplated by this Agreement shall be reduced by any applicable withholding taxes.

2.8 LLC Tax Election. Buyer, the Asset Sellers, E&EC and the Company each acknowledge that, effective October 1, 2003, the LLC elected to be treated as a corporation for U.S. federal income tax purposes, and the parties hereto agree to treat such election as a tax-free transaction for U.S. federal income tax purposes.

2.9 Bulk Sales Laws. Buyer and the Asset Sellers hereby waive compliance with any applicable bulk transfer laws related to the transactions contemplated hereby.

2.10 Expenses. Except as otherwise provided herein, each party will be solely responsible for its own costs and expenses (including those of its employees and attorneys’ fees) incurred in negotiating and consummating the transactions contemplated hereby; provided, however, that if a party fails to close upon satisfaction of all conditions set forth in Article XII, then such party shall pay all costs and expenses (including those of its employees and attorneys) of the other parties.

In addition, each Asset Seller hereby further agrees to maintain and preserve the confidential information pertaining to the Acquired Assets (subject to the exceptions in the NDA other than any exception based on Asset Sellers’ prior possession of such information before its transfer to Buyer), including reasonable efforts to preserve confidentiality of information disclosed to third parties under confidentiality provisions in agreements retained by the Asset Sellers.

Notwithstanding anything to the contrary herein, (i) if a claim is made before the expiration of the periods of survival set forth above in this Section 13.1, then (notwithstanding the expiration of such time period) the representation or warranty applicable to such claim shall survive until, but only for purposes of, the resolution of such claim, and (ii) Buyer’s right of set off with respect to any breach of a representation, warranty or covenant for which a claim is made prior to the expiration of the applicable period of survival set forth above shall continue as set forth in Section 13.6.

-61-

pursuant to this Agreement, (ii) any failure by any Asset Seller, the Company and E&EC, or, prior to the Closing, the LLC to perform or comply with any covenant applicable to it contained in this Agreement, (iii) any failure by the Asset Sellers to perform or comply with any covenant applicable to it contained in the Consulting Agreements, (iv) any Excess Leasehold Liabilities to the extent that a claim is brought by Buyer pursuant to the terms of this Article XIII on or before the eighth anniversary of the Closing Date, (v) any Post-Closing Balance Sheet Adjustment Amount payable to Buyer, (vi) any Indemnifiable Taxes, and (vii) any Outstanding Loan Amounts; provided that E&EC shall not be liable with respect to any breach or inaccuracy of a representation or warranty contained in Section 5.18 or any failure to perform or comply with any covenant contained in Sections 2.1(b), 11.8, 11.11(b), 11.14, 11.15 and 11.16 or the Consulting Agreements; provided further, that the obligation of the Asset Sellers to indemnify for any failure to comply with the covenants contained in Section 11.16(c) shall be several, and not joint. Buyer agrees to promptly remit any insurance or third party indemnity proceeds received with respect to any Losses paid by any of the Asset Sellers, the Company or E&EC, if and when received.

(b) Each of the Asset Sellers, severally and not jointly, agrees to indemnify and hold the Buyer Indemnified Parties, harmless (on an after-tax basis) for, from and against all Losses, incurred or sustained by the Buyer Indemnified Parties, or any of them, directly or indirectly, as a result of any Excluded Liabilities.

(c) Buyer agrees to indemnify and hold each Asset Seller and the Company, and their respective officers, directors, employees, agents and Affiliates (the “Asset Seller Indemnified Parties”), harmless for, from and against all Losses incurred or sustained by the Asset Seller Indemnified Parties, or any of them, directly or indirectly, as a result of (i) any breach or inaccuracy of a representation or warranty of Buyer contained in this Agreement or in any certificate, instrument, or other document delivered pursuant to this Agreement, (ii) any failure by Buyer to perform or comply with any covenant applicable to it contained in this Agreement, and (iii) any post-closing Tax obligation of the LLC that is not an Indemnifiable Tax.

(d) Notwithstanding anything to the contrary herein, (i) the Asset Sellers, the Company and E&EC shall not have any indemnification obligations for Losses under Section 13.2(a)(i) unless one or more Officer’s Certificates identifying Losses under Section 13.2(a)(i) by the Buyer Indemnified Parties, taken together, in excess of $25,000 in the aggregate (the “Deductible Amount”) has or have been delivered to the Asset Sellers, the Company and E&EC as provided in Section 13.3, in which case the Buyer Indemnified Parties shall be entitled to recover only such Losses excluding the Deductible Amount, and (ii) Buyer shall not have any indemnification obligations for Losses under Section 13.2(c)(i) unless one or more Officer’s Certificates identifying Losses under Section 13.2(c)(i) by the Asset Seller Indemnified Parties, taken together, in excess of the Deductible Amount has or have been delivered to Buyer as provided in Section 13.3, in which case the Asset Seller Indemnified Parties shall be entitled to recover only such Losses excluding the Deductible Amount.

-62-

(e) Notwithstanding anything to the contrary herein, in no event shall the aggregate indemnification payments under Sections 13.2(a)(i) through (iv) to be made by any Asset Seller or the Company exceed the sum of the aggregate Purchase Price paid to such Asset Seller or the Company and the aggregate Purchase Price payable to such Asset Seller or the Company; provided that any indemnification payment in respect of any Purchase Price payable to such Asset Seller or the Company shall solely be paid by set-off in accordance with Section 13.6; provided further that for purposes of this Section 13.2(e), the Purchase Price paid to ENBW and the Company shall include the ENBW Loan Amount and the Company Loan Amount respectively; provided further, that the foregoing limitations in this Section 13.2(e) shall not apply to indemnification payments required under Section 13.2(a)(ii) in respect of any failure by an Asset Seller to conform or comply with the covenants contained in Section 11.16(c).

(f) Notwithstanding anything to the contrary herein, in no event shall the aggregate indemnification payments under Sections 13.2(c)(i) and (ii) to be made by Buyer exceed $6,000,000, other than with respect to the covenants in Sections 2.3, 11.16(a) and 11.18(iii).

(g) Nothing herein shall limit the liability of the Asset Sellers, the Company or E&EC for claims for Losses in respect of (i) any Excluded Liabilities, (ii) any Excess Leasehold Liabilities, (iii) any Indemnifiable Taxes, and (iv) any Outstanding Loan Amounts.

(h) Nothing herein shall limit the liability of the Asset Sellers, the Company, E&EC or the LLC for any breach of any representation, warranty or covenant contained in this Agreement of any Collateral Agreement if the transactions contemplated hereby do not close.

13.3 Indemnification Procedure. A party seeking indemnification (the “Indemnified Party”) shall deliver an Officer’s Certificate to the party from whom indemnification is sought (the “Indemnifying Party”). An Indemnifying Party may object to such claim by written notice to such Indemnified Party in accordance with Section 13.4, specifying the basis for the Indemnifying Party’s objection, within 30 days following receipt by the Indemnifying Party of notice from such Indemnified Party regarding such claim. If no objection is made, subject to Section 13.2(d), the Indemnifying Party shall promptly pay the claim net of any unpaid Losses determined in accordance with this Article XIII owing to the Indemnifying Party by the Indemnified Party. For the purposes hereof, “Officer’s Certificate” shall mean a certificate signed by any officer of the Indemnified Party: (i) stating that the Indemnified Party has paid, sustained, incurred, or properly accrued, or reasonably anticipates that it will have to pay, sustain, incur, or accrue, Losses; and (ii) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid, sustained, incurred, or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant, Excluded Liability, Post-Closing Balance Sheet Adjustment Amount, Excess Leasehold Liabilities, Indemnifiable Taxes or Outstanding Loan Amounts to which such item is related.

-63-

13.4 Resolution of Conflicts; Arbitration.

(a) In case the Indemnifying Party shall object in writing to any claim or claims made in any Officer’s Certificate to recover Losses within 30 days after delivery of such Officer’s Certificate, such Indemnifying Party and the Indemnified Party shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Indemnifying Party and the Indemnified Party should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and the Indemnifying Party shall promptly pay to the Indemnified Party the amount of the claim agreed upon, if any.

(b) If no such agreement can be reached after good faith negotiation and prior to 60 days after delivery of an Officer’s Certificate, the Indemnified Party or the Indemnifying Party may demand arbitration of the matter unless the amount of the Loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration, and in either such event the matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to the Indemnified Party and the Indemnifying Party. In the event that, within 30 days after submission of any dispute to arbitration, the Indemnified Party and the Indemnifying Party cannot mutually agree on one arbitrator, then, within 15 days after the end of such 30-day period, the Indemnified Party and the Indemnifying Party shall each select one arbitrator. The two arbitrators so selected shall select a third arbitrator. If the Indemnifying Party does not select an arbitrator during this 15-day period, then the parties agree that the arbitration will be conducted by one arbitrator selected by the Indemnified Party.

(c) Any such arbitration shall be held in New York County, New York, under the rules then in effect of the American Arbitration Association. The arbitrator(s) shall determine how all expenses relating to the arbitration shall be paid, including the respective expenses of each party, the fees of each arbitrator and the administrative fee of the American Arbitration Association. The arbitrator or arbitrators, as the case may be, shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrator or majority of the three arbitrators, as the case may be, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrator or a majority of the three arbitrators, as the case may be, shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys’ fees and costs, to the same extent as a competent court of law or equity, should the arbitrators or a majority of the three arbitrators, as the case may be, determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of the arbitrator or a majority of the three arbitrators, as the case may be, as to the validity and amount of any claim in such Officer’s Certificate shall be final, binding, and conclusive upon the parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s). Within 30 days of a decision of the arbitrator(s) requiring payment by one party to another, such party shall make the payment to such other party.

-64-

(d) Judgment upon any award rendered by the arbitrator(s) may be entered in any court having jurisdiction.

13.5 Third Party Claims. In the event that any third party claim shall be instituted or asserted by any Person in respect of which payment may be sought under Section 13.2 (an “Indemnification Claim”), the Indemnified Party shall promptly cause written notice of the assertion of any Indemnification Claim of which it has knowledge which is covered by this indemnity to be forwarded to the Indemnifying Party. The Indemnifying Party shall have the right, at its sole option and expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the Indemnified Party, and to defend against, negotiate, settle or otherwise deal with any Indemnification Claim that relates to any Losses indemnified against hereunder. If the Indemnifying Party elects to defend against, negotiate, settle or otherwise deal with any Indemnification Claim that relates to any Losses indemnified against hereunder, it shall promptly notify the Indemnified Party of its intent to do so. If the Indemnifying Party elects not to defend against, negotiate, settle or otherwise deal with any Indemnification Claim which relates to any Losses indemnified against hereunder, fails to notify the Indemnified Party of its election as herein provided or contests its obligation to indemnify the Indemnified Party for such Losses under this Agreement, the Indemnified Party may defend against, negotiate, settle or otherwise deal with such Indemnification Claim. If the Indemnifying Party shall assume the defense of any Indemnification Claim, the Indemnified Party may participate, at his or its own expense, in the defense of such Indemnification Claim. The parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such Indemnification Claim. Notwithstanding anything in this Section 13.5 to the contrary, neither the Indemnifying Party nor the Indemnified Party shall, without the written consent of the other party, settle or compromise any Indemnification Claim or permit a default or consent to entry of any judgment unless the claimant and such party provide to such other party an unqualified release from all liability in respect of the Indemnification Claim. Notwithstanding the foregoing, if a settlement offer solely for money damages is made by the applicable third party claimant, and the Indemnifying Party notifies the Indemnified Party in writing of the Indemnifying Party’s willingness to accept the settlement offer and, subject to the applicable limitations of Section 13.2, pay the amount called for by such offer, and the Indemnified Party declines to accept such offer, the Indemnified Party may continue to contest such Indemnification Claim, free of any participation by the Indemnifying Party, and the amount of any ultimate liability with respect to such Indemnification Claim that the Indemnifying Party has an obligation to pay hereunder shall be limited to the lesser of (i) the amount of the settlement offer that the Indemnified Party declined to accept plus the Losses of the Indemnified Party relating to such Indemnification Claim through the date of its rejection of the settlement offer and (ii) the aggregate Losses of the Indemnified Party with respect to such Indemnification Claim. If the Indemnifying Party makes any payment on any Indemnification Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such Indemnification Claim.

-65-

13.6 Set-Off Rights. Buyer shall be entitled to withhold from payment and set-off against any unpaid Purchase Price an amount equal to any Losses that have not been paid by an Indemnifying Party when due in accordance with the terms of Section 13.3 and Buyer shall be entitled to set-off any Losses against any unpaid Purchase Price without regard for the date on which such Losses occurred; provided that for purposes of this Section 13.6, the Purchase Price paid to ENBW and the Company shall include the ENBW Loan Amount and the Company Loan Amount respectively.

13.7 No Right to Indemnification or Contribution of Asset Sellers. Notwithstanding anything to the contrary in this Agreement, none of the Asset Sellers, the Company or E&EC shall have any right to indemnification or contribution against any of the LLC, Buyer or Buyer Parent (other than pursuant to Section 13.2(c)) or any of their respective officers, directors, employees, agents, and Affiliates arising from any liability of or claim against any of the Asset Sellers, the Company or E&EC pursuant to the terms of this Agreement or any of the transactions contemplated hereby.

(b) by any of Buyer, the Asset Sellers or the Company if the Closing Date shall not have occurred by February 27, 2004, or such later date as the parties may mutually agree (the “End Date”) for any reason; provided, however, that the right to terminate this Agreement under this Section 14.1(b) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Closing Date to occur on or before such date and such action or failure to act constitutes a material breach of this Agreement;

(c) by any of Buyer, the Asset Sellers or the Company if a Governmental Entity shall have issued an Order or taken any other action, in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement, which Order is final and nonappealable; or

-66-

obligation on the part of any party hereto, or its Affiliates, officers, directors or stockholders, provided that each party shall remain liable for any breaches of this Agreement prior to its termination; and provided further that, the provisions of Section 11.4, Section 11.5, Article XV and this Section 14.2 of this Agreement shall remain in full force and effect and survive any termination of this Agreement.
