THE CLOSING

3.1. Closing.

The date on which the Closing actually occurs is hereinafter called the “Closing Date.” The Closing shall be effective for all purposes as of 12:01 a.m., New York City time, on the Closing Date.

3.2. Payment of Purchase Price.

(a) Upon the terms and subject to the conditions set forth in this Agreement, in consideration of the aforesaid sale, assignment, conveyance, transfer and delivery of the Purchased Assets, Buyer shall (i) pay to Seller cash in an aggregate amount equal to

(A) $173,100,000 (as may be adjusted pursuant to Section 3.2(b), the “Initial Amount”) plus (B) the amount, if any, by which the Closing Adjustment Amount exceeds the Target Adjustment Amount, or minus (C) the amount, if any, by which the Target Adjustment Amount exceeds the Closing Adjustment Amount (the “Purchase Price”), and (ii) assume and agree to pay, perform and otherwise discharge the Assumed Liabilities. For the avoidance of doubt, Buyer acknowledges that its assumption of, and agreement to pay, perform or otherwise discharge, the Assumed Liabilities constitutes an integral part of the consideration to be received by Seller in respect of the sale, assignment, conveyance, transfer and deliver of the Purchased Assets hereunder, and that, in the absence of such assumption and agreement by Buyer, Seller would not enter into this Agreement.

(b) Notwithstanding any provision hereof to the contrary, the Initial Amount shall be (i) increased at the rate of $32,877 per day for each day that the Closing Date occurs before September 1, 2006 and (ii) decreased at the rate of $32,877 per day for each day that the Closing Date occurs after September 1, 2006.

(c) At least three (3) Business Days prior to the Closing Date, Seller shall provide to Buyer its good faith estimate of the Closing Adjustment Amount, which estimate shall be certified in writing by an appropriate officer of Seller (the “Estimated Adjustment Amount”).

(d) At the Closing, in furtherance but not in duplication of Section 3.2(a), Buyer shall pay to Seller cash in an aggregate amount equal to (A) the Initial Amount plus (B) the amount, if any, by which the Estimated Adjustment Amount exceeds the Target Adjustment Amount, or minus (C) the amount, if any, by which the Target Adjustment Amount exceeds the Estimated Adjustment Amount (the “Closing Payment”). The Closing Payment shall be paid to Seller by Buyer at the Closing by wire transfer of immediately available funds to the account designated by Seller to Buyer at least two (2) Business Days prior to the Closing Date.

3.3. Adjustment to Purchase Price.

(a) Within sixty (60) days after the Closing Date, Seller shall deliver to Buyer, at Seller’s sole cost and expense, a statement setting forth the Closing Adjustment Amount (the “Closing Statement”). Contemporaneously, Seller shall deliver to Buyer a schedule setting forth a calculation of the Purchase Price and the amount of any payment to be made, and by whom, pursuant to Section 3.3(c).

(b) In the event that Buyer is in disagreement with the Closing Statement, Buyer shall, within ten (10) Business Days after receipt of the Closing Statement, notify Seller of such disagreements setting forth with specificity the nature and amounts thereof. In the event that Buyer is in disagreement with only a portion of the Closing Statement, Buyer or Seller, as the case may be, shall pay all undisputed amounts in the manner set forth in Section 3.3(c); and all other amounts shall be paid at such time as all disagreements are resolved in accordance with this Section 3.3(b). If Buyer is in disagreement with the Closing Statement, and Buyer notifies Seller within such ten (10) Business Day period in accordance with this Agreement, then the Parties shall promptly attempt to resolve such disagreements by negotiation. If the Parties are unable to resolve such disagreements within thirty (30) days following such notice of disagreement by Buyer, then the Parties shall appoint an Independent Accounting Firm within

forty-five (45) days following such notice, which shall review the Closing Statement and determine the Closing Adjustment Amount.

Resolution of any disagreements shall be made by the Independent Accounting Firm in a writing addressed to all Parties within thirty (30) days following referral to it by the Parties of such disagreements in accordance with this Agreement. The findings of such Independent Accounting Firm shall be final, binding and conclusive on the Parties.

(c) No later than the fifth (5th) Business Day following the determination of the Closing Adjustment Amount pursuant to Section 3.3(b), either (i) Seller shall pay Buyer the amount, if any, by which the Closing Payment exceeds the Purchase Price, or (ii) Buyer shall pay Seller the amount, if any, by which the Purchase Price exceeds the Closing Payment, in either case, together with simple interest accruing on such payment at the Prime Rate from and after the Closing Date through but not including the date of payment, by wire transfer of immediately available funds to an account designated by the receiving Party. As used herein, “Prime Rate” means, as of any date, the prime rate as published in The Wall Street Journal on such date or, if not published on such date, on the most recent date of publication.

3.4. Tax Reporting and Allocation of Purchase Price.

In the event that the Parties cannot agree on a mutually satisfactory allocation within such sixty (60) day period, the Parties shall appoint an Independent Accounting Firm that shall, at Seller’s and Buyer’s joint expense, determine the appropriate allocation. In the event that Buyer and Seller cannot promptly agree on the selection of an accounting firm to act as the Independent Accounting Firm, either Party may request the American Arbitration Association to appoint a nationally recognized independent accounting firm, and such appointment shall be final, binding and conclusive on Buyer and Seller. Resolution of any disagreements shall be made by the Independent Accounting Firm in a writing addressed to all Parties within thirty (30) days following referral to it by the Parties of such disagreements in accordance with this Agreement. The finding of such Independent Accounting

Firm shall be final, binding and conclusive on the Parties.

Buyer shall make each such Tax Return available for Seller’s review and approval no later than fifteen (15) Business Days prior to the due date for filing such Tax Return, it being understood that Seller’s failure to approve any such Tax Return shall not limit Buyer’s obligation to timely file such Tax Return and timely pay all Taxes shown to be due thereon.

All books, records and information obtained pursuant to this Section 6.5(c) or pursuant to any other Section that provides for the sharing of books, records and information or review of any Tax Return or other instrument relating to Taxes shall be kept confidential by the parties hereto in accordance with the terms and conditions set forth in the Confidentiality Agreement.

(d) In the event that a dispute arises between Seller and Buyer regarding Taxes or any amount due under this Section 6.5, the Parties shall attempt in good faith to resolve such dispute and any agreed-upon amount shall be promptly paid to the appropriate Party. If any such dispute is not resolved within thirty (30) days after notice thereof is given to any Party, the Parties shall submit the dispute to an Independent Accounting Firm for resolution, which resolution shall be final, binding and conclusive on the Parties. In the event that Buyer and Seller cannot promptly agree on the selection of an accounting firm to act as the Independent Accounting Firm, either Party may request the American Arbitration Association to appoint a nationally recognized independent accounting firm, and such appointment shall be final, binding and conclusive on Buyer and Seller. Notwithstanding anything in this Agreement to the contrary, the costs, fees and expenses of the Independent Accounting Firm in resolving the dispute shall be borne equally by Seller and Buyer. Any payment required to be made as a result of the resolution by the Independent Accounting Firm of any such dispute shall be made within five (5) Business Days after such resolution, together with any interest determined by the Independent Accounting Firm to be appropriate.

(e) To the extent that any Party receives a Tax refund or credit with respect to a Tax that was paid or incurred, in whole or in part, by the other Party, such receiving Party shall promptly pay the allocable portion of the amount of such Tax refund or credit to the other Party.

6.6. Advice of Changes. Prior to the Closing, each Party shall advise the other in writing with respect to any matter arising after the date of this Agreement of which that Party obtains Knowledge and which, if existing or occurring on or prior to the date of this Agreement, would have been required to be set forth in this Agreement, including any of the Schedules hereto. Seller shall promptly notify Buyer of any fact, event, circumstance or condition that constitutes or results in a breach of any of its representations and warranties in Article IV. Seller may, from time to time prior to the Closing, promptly supplement or amend the Schedules to this Agreement with respect to (a) any matter that existed as of the date of this Agreement and should have been set forth in any of the Schedules hereto and (b) any matter hereafter arising which, if existing as of the date of this Agreement, would have been required to be set forth in any of the Schedules hereto in order to make any representation or warranty set forth in this Agreement true and correct as of such date; provided, however, that, with respect to clause (a) above, any such supplemental or amended disclosure shall not be deemed to have been disclosed as of the date of this Agreement unless expressly consented to in writing by Buyer in Buyer’s sole and absolute discretion; and provided further, that, with respect to clause (b) above, any such supplemental or amended disclosure shall be deemed to have been disclosed as of the date of this Agreement other than for purposes of Section 7.1(f) or (g). Buyer shall promptly notify Seller of (i) any breach by Seller of any representation or warranty of Seller, and (ii) any other event, fact, circumstance or condition that would excuse Buyer from the timely performance of its obligations hereunder. In the event that Buyer fails to so notify Seller within ninety (90) days of such information coming to Buyer’s attention, then Buyer shall be deemed to have irrevocably and unconditionally waived the breach of such representation and warranty or the performance of such obligations, as the case may be.

6.7. Risk of Loss.

(a) From the date hereof to but not including the Closing Date, all risk of loss or damage to the Tangible Personal Property included in the Purchased Assets shall be borne by Seller, other than loss or damage caused by the negligent acts or omissions of Buyer or any Buyer Representative, which loss or damage shall be the responsibility of Buyer.

(b) Notwithstanding any provision hereof to the contrary, subject to Section 9.1(g), if, before the Closing Date, all or any portion of the Purchased Assets at any Jointly Owned Station is (i) condemned or taken by eminent domain or is the subject of a pending or threatened condemnation or taking which has not been consummated, or (ii) materially damaged or destroyed by fire or other casualty, Seller shall notify Buyer promptly in writing of such fact, and (x) in the case of a condemnation or taking, Seller shall assign or pay, as the case may be, any net proceeds thereof to Buyer at the Closing relating to such Purchased Assets and (y) in the case of a fire or other casualty, Seller shall either restore such damage or assign the insurance proceeds therefor to Buyer at such Closing. Notwithstanding the foregoing, if such condemnation, taking, damage or destruction results in a Material Adverse Effect, Buyer and Seller shall negotiate to resolve the loss resulting from such condemnation, taking, damage or destruction (and such negotiation shall include the negotiation of a fair and equitable adjustment to the Purchase Price for such Purchased Assets). If no such resolution can be agreed upon prior to the earlier to occur of (i) the date that is ninety (90) days after Seller has notified Buyer of such loss, and (ii) the date on which the Closing, pursuant to Section 3.1, would otherwise occur, then Buyer, on the one hand, or Seller, on the other hand, may terminate this Agreement with respect to such Purchased Assets pursuant to Section 9.1(g).

6.8. PJM; MAAC. From and after the Closing Date, Buyer shall maintain membership in good standing in PJM and MAAC, and shall submit to the governance of the independent system operator established and administered under the PJM Agreement and related agreements entered into among PJM and its members.

6.10. Certain Covenants.

(a) From and after the date hereof and until the Closing Date, unless Buyer shall otherwise consent in writing (which consent shall not be unreasonably withheld or delayed), other than the periodic revision and adoption of Keystone-Conemaugh Owners Committee Administrative Procedures in the ordinary course of business consistent with past practice, Seller shall not enter into any contract, agreement, commitment or arrangement relating to the Purchased Assets or the Jointly Owned Stations that provides for future annual payments by Seller in excess of $50,000 unless such contract, agreement, commitment or arrangement is (i) terminable by Seller prior to the Closing or by Buyer at or after the Closing, without payment of penalty or premium, upon no more than ninety (90) days’ notice, (ii) constitutes an Excluded Asset and Excluded Liability or (iii) has been executed by all co-owners of any Jointly Owned Station (other than Seller), it being understood that this Section 6.10(a) is not intended to, and shall not, restrict in any manner the ability of Keystone Fuels, LLC, Conemaugh Fuels, LLC or the operator of any Jointly Owned Station from entering into any contract, agreement, commitment or arrangement without such consent.

(c) All communications and consultations contemplated by Sections 6.1(a), 6.3, 6.4 and 6.10(b) shall take place between the respective designated representatives of Seller and Buyer, as may be designated from time to time by Seller and Buyer in the manner contemplated by Section 10.8.

ARTICLE VIII

INDEMNIFICATION AND ARBITRATION

8.1. Indemnification.

(a) From and after the Closing Date, Buyer shall indemnify, defend and hold harmless Seller and its Representatives (each, a “Seller’s Indemnitee”), from and against any and all claims, demands, suits, losses, liabilities, penalties, damages, obligations, payments, costs and expenses (including reasonable attorneys’ fees and expenses in connection therewith) (each, an “Indemnifiable Loss”), asserted against or suffered by any Seller’s Indemnitee relating to, resulting from or arising out of (i) any breach by Buyer of any (A) representation and warranty set forth in Article V, or (B) covenant or agreement of Buyer contained in this Agreement, (ii) the Assumed Liabilities, (iii) any Inspection, (iv) the failure by Buyer to comply with any Law, with respect to the Purchased Assets that are subject thereto or (v) any Third-Party Claim against any Seller’s Indemnitee in connection with Buyer’s ownership, lease, maintenance, construction, modification or operation of any of the Purchased Assets on or after the Closing Date (other than to the extent such Third-Party Claim constitutes an Excluded Liability); provided, however, that Buyer shall be liable to the Seller’s Indemnitees pursuant to clause (i) of this Section 8.1(a) only for Indemnifiable Losses for which any Seller’s Indemnitee gives written notice to Buyer (setting forth with reasonable specificity the nature and amount of the Indemnifiable Loss) during the period for which such representations, warranties, covenants or agreements survive the Closing in accordance with Section 10.6; and provided further that Buyer shall be liable to the Seller’s Indemnitees pursuant to clause (i)(A) of this Section 8.1(a) for breaches of representations and warranties (y) only after Indemnifiable Losses for such breaches, in the aggregate, exceed $2,000,000 (provided, however, that once such threshold amount is exceeded, Seller’s Indemnitees may recover all Indemnifiable Losses for such breaches incurred from and after the Closing Date without regard to such threshold amount), and (z) only for Indemnifiable Losses for such breaches, in the aggregate, up to, but not in excess of, $17,500,000 (other than for breaches of the representations and warranties set forth in Sections 5.1, 5.2 and 5.5, as to which no such limitations shall be applicable).

(b) From and after the Closing, Seller shall indemnify, defend and hold harmless Buyer and its Representatives (each, a “Buyer’s Indemnitee” and, together with Seller’s Indemnitees, an “Indemnitee”), from and against any and all Indemnifiable Losses asserted against or suffered by any Buyer’s Indemnitee relating to, resulting from or arising out of (i) any breach by Seller of any (A) representation and warranty set forth in Article IV, or (B) covenant or agreement of Seller set forth in this Agreement, (ii) the Excluded Assets and the Excluded Liabilities or (iii) any Third-Party Claim against any Buyer’s Indemnitee in connection with Seller’s ownership, lease, maintenance, construction, modification or operation of any of the Purchased Assets prior to the Closing Date (other than to the extent such Third-Party Claim constitutes an Assumed Liability); provided, however, that Seller shall be liable to the Buyer’s Indemnitees pursuant to clause (i) of this Section 8.1(b) only for Indemnifiable Losses for which any Buyer’s Indemnitee gives written notice to Seller (setting forth with reasonable specificity the nature and amount of the Indemnifiable Loss) during the period for which such representations, warranties, covenants or agreements survive the Closing in accordance with Section 10.6; and provided further that Seller shall be liable to the Buyer’s Indemnitees pursuant

to clause (i)(A) of this Section 8.1(b) for breaches of representations and warranties (y) only after Indemnifiable Losses for such breaches, in the aggregate, exceed $2,000,000 (provided, however, that once such threshold amount is exceeded, Buyer’s Indemnitees may recover all Indemnifiable Losses for such breaches incurred from and after the Closing Date without regard to such threshold amount), and (z) only for Indemnifiable Losses for such breaches, in the aggregate, up to, but not in excess of, $17,500,000 (other than for breaches of the representations and warranties set forth in Sections 4.1, 4.2 and 4.5, as to which no such limitations shall be applicable).

(c) In furtherance, and not in limitation, of the provisions set forth in Section 8.1(a), Buyer, for itself and on behalf of its Representatives, hereby irrevocably releases, holds harmless and forever discharges Seller from any and all Indemnifiable Losses of any kind or character, whether known or unknown, contingent or accrued, arising under or relating to Environmental Laws, or relating to any claim in respect of any Environmental Condition or Hazardous Substance, whether based on common law or Environmental Laws, relating to the Purchased Assets, other than Excluded Liabilities (collectively, “Environmental Claims”). In furtherance of the foregoing, Buyer, for itself and on behalf of its Representatives, hereby irrevocably waives any and all rights and benefits with respect to such Environmental Claims that it now has, or in the future may have conferred upon it by virtue of any Law or common law principle, which provides that a general release does not extend to claims which a party does not know or suspect to exist in its favor at the time of executing the release, if knowledge of such claims would have materially affected such party’s settlement with the obligor. In this connection, Buyer hereby acknowledges that it is aware that factual matters now unknown to it may have given, or hereafter may give, rise to Environmental Claims that have not been made prior to the date of this Agreement, and will not be made prior to the Closing Date, and Buyer further agrees that this release set forth in this Section 8.1(c) has been negotiated and agreed upon in light of that awareness, and Buyer, for itself and on behalf of its Representatives, nevertheless hereby intends irrevocably to release, hold harmless and forever discharge Seller from all such Environmental Claims.

(d) The rights and remedies of Seller and Buyer set forth in this Article VIII are exclusive and in lieu of any and all other rights and remedies which Seller and Buyer may have under this Agreement, under applicable Law, whether at common law or in equity, including for declaratory, injunctive or monetary relief, in each case, with respect to any Indemnifiable Loss.

(e) Notwithstanding anything to the contrary herein, no Person (including an Indemnitee) shall be entitled to recover from any other Person (including any Party required to provide indemnification under this Agreement (an “Indemnifying Party”)) any amount in excess of the actual compensatory damages, court costs and reasonable attorneys’ fees suffered by such Party. In furtherance of the foregoing, Buyer and Seller hereby irrevocably waive any right to recover punitive, indirect, special, exemplary and consequential damages arising in connection with or with respect to this Agreement (other than with respect to indemnification for a Third- Party Claim).

(f) Any Indemnitee shall use Commercially Reasonable Efforts to mitigate all losses, damages and the like relating to a claim under the indemnification provisions in this

Section 8.1, including availing itself of any defenses, limitations, rights of contribution, claims against third Persons and other rights at law or equity. For purposes of this Section 8.1(f), the Indemnitee’s Commercially Reasonable Efforts shall include the reasonable expenditure of money to mitigate or otherwise reduce or eliminate any Indemnifiable Loss for which indemnification would otherwise be due, and, in addition to its other obligations hereunder, provided that the Indemnifying Party shall reimburse the Indemnitee for the Indemnitee’s reasonable costs and expenses incurred in undertaking such mitigation, reduction or elimination.

8.2. Defense of Claims.

(a) If any Indemnitee receives notice of the assertion of any Indemnifiable Loss or of the commencement of any suit, action or proceeding made or brought by any Person who is not an Indemnitee (a “Third-Party Claim”) with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in no event later than twenty (20) Business Days after the Indemnitee’s receipt of notice of such Third-Party Claim. Such notice shall describe the nature of the Third-Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the Indemnifiable Loss that has been or may be incurred by the Indemnitee. The Indemnifying Party shall have the right to participate in or, by giving written notice to the Indemnitee, to elect to assume the defense of any Third-Party Claim at such Indemnifying Party’s expense and by such Indemnifying Party’s own counsel. If an Indemnifying Party elects not to assume the defense of any Third-Party Claim, the Indemnitee may defend, compromise or settle such Third-Party Claim with counsel selected by it, provided that, without the prior written consent of the Indemnifying Party, the Indemnitee shall not agree to the entry of any judgment with respect to, or any compromise or settlement of, any Third-Party Claim.

(b) If the Indemnifying Party undertakes, conducts and controls the conduct and settlement of such action or suit, (i) the Indemnifying Party shall not thereby permit to exist any Encumbrance upon any asset of the Indemnitee; (ii) the Indemnifying Party shall not consent to any settlement that does not include as an unconditional term thereof the giving of a complete release from Liability with respect to such action or suit to the Indemnitee; and (iii) the Indemnifying Party shall permit the Indemnitee to participate in such conduct or settlement at such Indemnitee’s expense and by such Indemnitee’s counsel.

(c) Subject to Section 8.3, any claim by an Indemnitee on account of an Indemnifiable Loss which does not constitute a Third-Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, in no event later than forty (40) Business Days after the Indemnitee becomes aware of such Direct Claim, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable, of such Indemnifiable Loss. The Indemnifying Party shall have a period of forty (40) Business Days within which to respond to such Direct Claim. If the Indemnifying Party fails to respond during such forty (40) Business Day period, the Indemnifying Party shall be deemed to have accepted such claim and, subject to this Article VIII, shall promptly reimburse the Indemnitee for the Indemnifiable Losses set forth in the Indemnitee’s notice.

(d) A failure to give timely notice as provided in this Section 8.2 shall not affect the rights or obligations of any Party hereunder except to the extent that the Party which was entitled to receive such notice was actually prejudiced as a result of such failure.

8.3. Arbitration.

(a) Notwithstanding any provision hereof to the contrary, in the event of any dispute between Seller and Buyer arising after the Closing (whether relating to facts, events or circumstances occurring or existing prior to, on or after the Closing Date) and relating to, resulting from or arising out of any provision of this Agreement (other than disputes arising under Article II or Section 3.2, 3.3, 3.4, 6.5, 8.1(a)(ii) or 8.1(b)(ii)), including with respect to Direct Claims and Third Party Claims, the Party asserting such dispute shall give written notice to the other of the fact that a dispute has arisen pursuant hereto. Such notice shall include (i) a statement setting forth in reasonable detail the facts, events, circumstances, evidence and arguments underlying such dispute and (ii) proposed arrangements for a meeting to attempt to resolve the dispute to be held within sixty (60) days after such notice is given. Within thirty (30) days after such notice is given, the other Party hereto shall submit to the Party giving such notice a written summary responding to such statement of facts, events, circumstances, evidence and arguments contained in the notice and an acceptance of or proposed alternative to the meeting arrangements set forth in the initial notice.

(b) The chief executive officers (or any other executive officer or officers directly reporting to, or duly designated by, such chief executive officers) of each of the Parties shall meet at a mutually acceptable time and place to attempt to settle any dispute in good faith; provided, however, that such meeting shall be held at the principal offices of the Party receiving the notice of dispute unless otherwise agreed; and provided further, that any such meeting shall be held no later than sixty (60) days after the written notice of dispute is given pursuant to Section 8.3(a). Each Party shall bear its own costs and expenses with respect to preparation for, attendance at and participation in such meeting.

(c) In the event that (i) a meeting has been held in accordance with Section 8.3(b), (ii) any such dispute of the kind referred to in Section 8.3(a) shall not have been resolved at such meeting and (iii) the aggregate amount in dispute exceeds $100,000, then either Party may submit such dispute to binding arbitration pursuant to the Commercial Arbitration Rules of the American Arbitration Association (the “Commercial Arbitration Rules”). In the event that such dispute is submitted to arbitration pursuant to the Commercial Arbitration Rules, then the arbitration tribunal shall be composed of three arbitrators (one arbitrator selected by each Party within thirty (30) days after the meeting held in accordance with Section 8.3(b) with the third selected by the other two arbitrators or, in the absence of agreement between them, the American Arbitration Association), the venue of the arbitration shall be Wilmington, Delaware, the language of the arbitration shall be English and the arbitration shall commence no later than sixty (60) days after the meeting held in accordance with Section 8.3(b). The decision, judgment and order of the arbitration tribunal shall be final, binding and conclusive as to the Parties and their respective Representatives, and may be entered in any court of competent jurisdiction. Other than the fees and expenses of the arbitrators, which shall be shared equally by the Parties, each Party shall bear its own costs and expenses (including attorneys’ fees and expenses) relating to the arbitration.

(h) This Agreement may be terminated by either Party with respect to the Purchased Assets at any Jointly Owned Station, upon written notice to the other Party, if any final and non-appealable injunction, order or decree by any Governmental Authority, which prohibits the consummation of the transactions contemplated hereby or by the Additional Agreements to the extent relating to such Purchased Assets, shall have been issued and remain in effect, provided that the Party seeking to terminate this Agreement pursuant to this Section 9.1(h) shall have used its Commercially Reasonable Efforts to have any such injunction, order or decree lifted.

9.2. Effect of Termination.

(a) Upon termination of this Agreement prior to the Closing in accordance with and pursuant to Section 9.1 with respect to the Purchased Assets at any Jointly Owned Station, this Agreement shall be of no further force or effect with respect to such Purchased Assets (except that the provisions set forth in Section 6.1(b), Section 6.2, this Section 9.2 and Article X, and the Confidentiality Agreement, shall remain in full force and effect in accordance with their respective terms); and no Party shall have any further Liability under this Agreement (other than for any breach of any of its covenants and agreements set forth herein).

10.10. Governing Law; Forum; Service of Process. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware (without giving effect to conflicts of law principles) as to all matters, including validity, construction, effect, performance and remedies. Venue in any and all suits, actions and proceedings related to the subject matter of this Agreement shall be in the state and federal courts located in and for the State of Delaware (the “Courts”), which shall have exclusive jurisdiction for such purpose, and the Parties hereby irrevocably submit to the exclusive jurisdiction of such courts and irrevocably waive the defense of an inconvenient forum to the maintenance of any such suit, action or proceeding. Service of process may be made in any manner recognized by such Courts. Each of the Parties hereby irrevocably waives its right to a jury trial arising out of any dispute in connection with this Agreement or the transactions contemplated hereby. Buyer has irrevocably appointed Corporation Service Company, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, as its authorized agent (the “Authorized Agent”) upon which process may be served in any suit, action or proceeding based on this Agreement which may be instituted in the Courts by Seller, and Buyer expressly accepts the jurisdiction of any such Court in respect of any such suit, action or

proceeding. Buyer represents and warrants that the Authorized Agent has agreed to act as such agent for service of process, and Buyer shall take any and all actions, including the filing of any and all documents and instruments, which may be necessary or appropriate to continue such appointment in full force and effect. Service of process upon the Authorized Agent and written notice of such service to Buyer shall be deemed, in every respect, effective service of process upon Buyer.

10.12. Interpretation. The Article and Section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and shall not in any way affect the meaning or construction of this Agreement. Ambiguities and uncertainties in the wording of this Agreement shall not be construed for or against any Party, but shall be construed in the manner that most accurately reflects the Parties’ intent as of the date of this Agreement. Each Party acknowledges that it has been represented by counsel in connection with the review and execution of this Agreement, and, accordingly, there shall be no presumption that this Agreement or any provision hereof be construed against the Party that drafted this Agreement. Notwithstanding any provision of any Additional Agreement to the contrary, the provisions of this Agreement shall govern and control any conflict or inconsistency between or among the provisions of this Agreement and the provisions of any such Additional Agreement.

10.13. Schedules and Exhibits. Except as otherwise provided in this Agreement, all Exhibits and Schedules referred to herein are intended to be and hereby are made a part of this Agreement.

10.14. Disclosure. Each Schedule to this Agreement shall be deemed to include and incorporate all information set forth on the other Schedules. Information disclosed in documents set forth on a Schedule shall be deemed to be disclosed on the Schedules. Certain information set forth on the Schedules is included solely for informational purposes, is not an admission of liability or materiality with respect to the matters covered by the information, and may not be required to be disclosed pursuant to this Agreement. The specification of any Dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the Schedules is not intended to imply that such amounts (or higher or lower amounts) or such items are or are not material, and no Party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the Schedules in any dispute or controversy among the Parties as to whether any obligation, item or matter not described herein or included in a Schedule is or is not material for purposes of this Agreement.

10.15. Entire Agreement. This Agreement (including the Schedules and Exhibits), together with the Additional Agreements (when executed and delivered by the Parties) and the Confidentiality Agreement, constitute a single integrated agreement between the Parties and, together, embody the entire agreement and understanding of the Parties hereto in respect of the transactions contemplated hereby and thereby, and supersede all prior agreements and understandings between the Parties with respect to such transactions. There are no representations, warranties, covenants or agreements between the Parties with respect to the

subject matter set forth in such agreements, other than those expressly set forth or referred to herein or therein. Without limiting the generality of the foregoing, Buyer hereby acknowledges and agrees that there are no representations, warranties, covenants or agreements between the Parties with respect to the subject matter set forth in such agreements contained in any material made available to Buyer pursuant to the terms of the Confidentiality Agreement (including the Offering Memorandum dated June 15, 2005, previously provided to Buyer by or on behalf of Seller and Concentric Energy Advisors, Inc.).
