If such an appraisal is made, it shall be binding upon both Buyer and Seller. Each Party shall bear and pay one-half of the fees and other costs charged by the Independent Appraiser. Each of Buyer and Seller agrees to file Internal Revenue Service Form 8594 and all federal, state, local and foreign Tax Returns in accordance with such agreed allocation (giving effect to mutually-agreed upon adjustments as a result of adjustments to the Purchase Price pursuant to Section 2.9).

Section 5.1 General. Prior to the Closing and subject to the terms and conditions of this Agreement, each of the Parties will use its commercially reasonable efforts to take all actions required of it by this Agreement that are necessary, proper or advisable in order to consummate

and make effective the transactions contemplated by this Agreement and the Ancillary Agreements (including satisfaction, but not waiver, of the closing conditions set forth in Articles VI and VII that such Person is required to satisfy).

(a) Each Party will and will cause its respective applicable Affiliates to, in order to consummate the transactions contemplated hereby, (i) take all commercially reasonable steps necessary, and proceed diligently and in good faith and use all commercially reasonable efforts, to obtain as promptly as practicable the Seller’s Required Consents and the Buyer’s Required Consents applicable to such Person and to make all required filings required to be made by it with, and to give all notices required to be given by it to, Governmental Authorities, and (ii) provide such other information and communications to such Governmental Authorities or other Persons as such Governmental Authorities or other Persons may reasonably request in connection therewith. Each Party agrees that it will accept the terms of all Permits as existing on the date of this Agreement (including the Environmental Permits) relating to the operation of the Acquired Assets, and shall not seek to amend any of such terms in connection with filings relating to the transactions contemplated by this Agreement, other than as necessary to effect the transfer of such Permits. Notwithstanding anything to the contrary in this Agreement, none of Buyer or its Affiliates shall be required to agree to take or refrain from taking any action in connection with a Seller’s Required Consent or a Buyer’s Required Consent that could reasonably be expected to result in a Burdensome Condition. Seller shall reasonably cooperate with Buyer in providing such notices to counterparties to Assigned Contracts as may be required by the terms of such Assigned Contracts or as Buyer (acting reasonably) may deem necessary, including notices providing counterparties with updated notice information and updated bank account information to which any applicable payments should be made by such counterparties.

(b) The Parties will provide prompt notification to each other when any such consent referred to in Section 5.2(a) is obtained, taken, made, given or denied, as applicable, and will, subject to Section 5.2(c), advise each other of any material communications with any Governmental Authority or other Person regarding any of the transactions contemplated by this Agreement.

(i) Within two (2) Business Days following execution of this Agreement, Seller shall notify the Division as required by the Final Judgment and, as soon as is practical following the execution of this Agreement, Buyer shall prepare all necessary filings required to be made with the Federal Energy Regulatory Commission under Section 203 of the Federal Power Act, and each Party shall prepare all other necessary filings in connection with the transactions contemplated by this Agreement that may be required to be filed by such Party with applicable Governmental Authorities or under any applicable Laws. Except as set forth in the immediately preceding sentence, each Party shall submit such filings as soon as practicable, but in no event later than fifteen (15) days (subject to extension by mutual written agreement) after the execution hereof. The Parties shall take commercially reasonable efforts to respond to any questions or information requests of the Division and to comply with the timelines set forth in the

Final Judgment. The Parties shall request expedited treatment of any such filings (where applicable), promptly furnish each other with copies of any notices, correspondence or other written communication from the relevant Governmental Authority, promptly make any appropriate or necessary subsequent or supplemental filings, submissions or responses to any Governmental Authority, and cooperate in the preparation of such filings, submissions or responses as is reasonably necessary and appropriate. Subject to the last sentence in this Section 5.2(c)(i), (x) each Party shall have the right to review in advance all information related to Seller, the Facilities, the Acquired Assets or Buyer, as applicable, and the transactions contemplated by this Agreement with respect to any filing, submission or response with any Governmental Authority made by the other Party in connection with the transactions contemplated by this Agreement; (y) prior to the submission by Buyer of any filings to be made pursuant to this Section 5.2, Buyer shall provide to Seller a draft of each such filing, submission and response and reasonable opportunity to review and comment on each such filing; and (z) Buyer and Seller shall cooperate with each other to, and shall use reasonable efforts to, incorporate the other’s comments into such filings. Notwithstanding the foregoing, neither Buyer nor Seller shall be obligated to share any information, filing, submission or responses with the other Party if a Governmental Authority objects to the sharing of such information, filings, submission or response.

(iii) The Parties shall not, and shall cause their respective Affiliates not to, take any action that would reasonably be expected to adversely affect or delay the approval of any Governmental Authority of any of the filings referred to in Section 5.2(c).

(iv) Seller shall, and shall cause its Affiliates that own or are counterparties to any Acquired Assets to, use best efforts to, and Buyer shall use commercially reasonable efforts to, secure the transfer or reissuance of the Permits (including the Transferred Permits), Emission Allowance compliance accounts for the Facilities, Seller’s Required Consents and Buyer’s Required Consents, effective as of the Closing Date. Each of Seller and Buyer shall cooperate with the other Party in this regard, and Seller shall use best efforts to, and Buyer shall use commercially reasonable efforts to, assist in such transfer or reissuance. If the Parties are unable to secure such transfer or reissuance effective on the Closing Date, the Parties shall continue to reasonably cooperate with the other Party’s efforts to secure such transfer or reissuance following the Closing Date.

(d) The Parties hereto shall consult with each other prior to proposing or entering into any stipulation or agreement with any Governmental Authority or any third party whose consent is a Seller’s Required Consent or a Buyer’s Required Consent in connection with any Federal, State or local governmental consents and approvals legally required for the consummation of the transactions contemplated hereby, and shall not propose or enter into any such stipulation or agreement without the other Party’s prior written consent, which consent shall not be unreasonably withheld.

(a) During the Interim Period, Seller will (i) provide Buyer and its Representatives with reasonable access, upon reasonable prior notice and during normal business hours, to all premises, properties, management, personnel, books, records (including Tax records) and documents associated with the Acquired Assets and permit Buyer and such Representatives to make such reasonable inspections thereof as Buyer may reasonably request (and Buyer shall be entitled, at its expense, to have the Sites surveyed and to conduct non-invasive physical inspections (which shall exclude any Phase I environmental site assessment)) provided, however, that Buyer shall not be entitled (A) to perform any Phase 1 environmental studies, or (B) to collect any air, soil, surface water or ground water samples nor to perform any invasive or destructive sampling on the Sites); (ii) subject to the receipt of any required consents and in accordance with applicable Laws, provide Buyer with such information and records (including payroll records) regarding Seller Employees and Off-Site Employees as Buyer reasonably deems necessary to comply with the obligations of this Agreement; (iii) furnish Buyer with a copy of each material report, schedule or other document filed or received by it or its Affiliates with respect to the Acquired Assets with a Governmental Authority. Notwithstanding the foregoing, and without limiting the generality of the confidentiality provisions set forth in Section 5.15, Seller shall not supply Buyer with any information or records if, and to the extent, prohibited by applicable Law.

(b) During the Interim Period, at the sole cost and expense of Buyer, Seller will permit designated employees or Representatives of Buyer (the “Buyer’s Observers”) to observe all operations of Seller related to the Acquired Assets, with such observation permitted on a cooperative basis in the presence of personnel of Seller during normal business hours of Seller; provided that (i) Buyer’s Observers shall not unreasonably interfere with the operation of the Acquired Assets by Seller, and (ii) with respect to each such episode of observation, Buyer shall provide Seller with not less than two (2) Business Days’ prior notice before any such observation shall be permitted.

(c) Buyer agrees to indemnify and hold harmless Seller, its Affiliates and their Representatives for any and all Loss incurred by Seller, its Affiliates or their Representatives to the extent arising out of any exercise of the access rights under this Section 5.3, including any Claims by any of Buyer’s Representatives for any injuries or property damage while present at the Facilities, except in cases of Seller’s or its Representatives’ willful misconduct.

(d) For a period of seven (7) years after the Closing Date, Seller shall have reasonable access to, or at Buyer’s option copies of, all of the records, books and documents related to the Acquired Assets of Buyer to the extent relating primarily to the Acquired Assets and relating to periods ending prior to the Closing Date and to the extent that such access may reasonably be required in connection with matters relating to the operations of Seller on or prior to the Closing Date (including liabilities with respect to Taxes); provided that Seller shall have the right, at its sole cost and expense, to retain copies of such records, books and documents, subject to its obligation to keep such information confidential in accordance with Section 5.15. Such access shall be afforded upon receipt of reasonable advance notice and during normal business hours. Seller shall be solely responsible for any costs or expenses incurred by it pursuant to this Section 5.3(d). If Buyer shall desire to dispose of any records, books or documents with respect to

operation of the Acquired Assets before the Closing prior to the expiration of such seven-year period, Buyer shall, prior to such disposition, give to Seller a reasonable opportunity, at Seller’s expense, to segregate and remove such records, books or documents as Seller may select. Notwithstanding anything contrary in this Agreement, in no event shall Seller or any of its Affiliates be required to provide access to, or copies of, any Tax Returns of Seller or any of its Affiliates.

(e) During the Interim Period, not less than two (2) Business Days prior to initiating contact or communication with any Governmental Authority or counterparty to any Assigned Contract, in each case with respect to which a Buyer’s Required Consent or a Seller’s Required Consent is required, Buyer shall provide Seller with (i) notice of such planned contact or communication and (ii) the opportunity to participate in such contact or communication; provided, for the avoidance of doubt, that where Seller does not elect to so participate, Buyer shall be free to proceed with such contact or communication without Seller’s participation.

Section 5.4 Operation of Business. Except as set forth on Schedule 5.4, during the Interim Period, Seller will, and will cause its applicable Affiliates to, (1) operate and maintain the Acquired Assets (including maintaining the Permits and Material Contracts) in the ordinary course of business consistent with past practices and Good Utility Practice, and (2) use commercially reasonable efforts to complete the Budgeted Capital Expenditures in accordance with Good Utility Practice, unless otherwise expressly contemplated by this Agreement or with the prior written consent of Buyer (such consent not to be unreasonably withheld). Without limiting the generality of the foregoing, except as set forth on Schedule 5.4, Seller shall not, and shall cause its Affiliates not to, without the prior written consent of Buyer (which consent shall not be unreasonably withheld), during the Interim Period, with respect to the Acquired Assets and Assumed Liabilities:

(a) except for Acquired Assets used at or consumed by the Facilities in the ordinary course of business consistent with past practice and Good Utility Practice, (i) sell, lease (as lessor), license (as licensor), transfer or otherwise dispose of any of the Acquired Assets, or (ii) encumber, pledge, mortgage or suffer to be imposed on any of the Acquired Assets any Lien other than Permitted Liens;

(c) except for any Permitted Contract, (i) enter into any Contract of a type described in Section 3.12(a), (ii) grant any waiver of any material term under, or give any material consent with respect to, any Material Contract, or (iii) terminate, enter into, amend or grant any waiver of any material term or give any material consent with respect to any Contract for the transmission of electricity or that relates to the purchase, sale or transportation of Fuel Inventory that relates to any period after the later of March 31, 2013 and Closing; provided that nothing in this clause shall inhibit the ability of Seller to terminate, amend or modify Contracts as required by Law; and provided further that during the Interim Period, Schedules 2.1(f) and/or 3.12, as applicable, shall be amended to account for any Contract permitted under this Section 5.4(c);

(d) make any capital expenditures or enter into a Capital Commitment with respect thereto, except with respect to (i) capital expenditures or Capital Commitments necessitated by Good Utility Practice that do not exceed $5,000,000 in the aggregate, (ii) as may be necessitated by an emergency situation (in which case Seller shall promptly notify Buyer of such expenditure) or (iii) Budgeted Capital Expenditures; provided that, during the Interim Period, Schedules 2.1(f) and/or 3.12, as applicable, shall be amended to account for any capital expenditure or Capital Commitment permitted under this Section 5.4(d);

(e) increase the level of wages, compensation or other benefits of any Seller Employees or Off-Site Employees (except for increases in salary or hourly wage rates in the ordinary course of business consistent with past practice or the payment of accrued or earned but unpaid bonuses);

(f) terminate the employment of any Seller Employee or Off-Site Employee except for cause, or hire any Seller Employee, in each case other than as consistent with past practice;

(g) enter into any collective bargaining agreement with respect to any Seller Employee or Off-Site Employee or enter into any employment agreement, severance, retention or bonus agreement or other Contract with or with respect to a Seller Employee or Off-Site Employee;

(i) terminate, renew, amend, modify or replace any Permit, other than in the ordinary course of business consistent with past practices and Good Utility Practice and on terms and conditions that are not materially less favorable to any of the Facilities or the other Acquired Assets than under the Permit being so renewed;

(k) otherwise take any action that will impede in any way the permitting, operation or contemplated divestiture to Buyer of the Acquired Assets;

(l) take any action that could reasonably be expected to adversely affect Seller’s queue position W3-122 with respect to the merchant transmission project; and

Notwithstanding the foregoing, Seller may (A) to the extent required by applicable Law, and without Buyer’s prior written consent, take any action otherwise prohibited by this Section 5.4; provided, that Seller shall promptly inform Buyer upon taking any such action, and (B) enter into any agreement with any Seller Employee or Off-Site Employee who does not accept Buyer’s or its Affiliate’s offer of employment, provided that Buyer shall have no Liability under or with respect to any such agreement.

Section 5.5 Discharge of Business Obligations After Closing. From and after the Closing, (i) if Buyer or any of its Affiliates receives or collects any funds arising from or relating to the Excluded Assets, Buyer or its Affiliates shall remit such funds, to the extent arising from or relating to the Excluded Assets, to Seller within five (5) Business Days after its receipt thereof and (ii) if Seller or any of its Affiliates receives or collects any funds arising from or relating to the Acquired Assets, Seller or its Affiliates shall remit such funds, to the extent arising from or relating to the Acquired Assets, to Buyer within five (5) Business Days after its receipt thereof.

Section 5.6 Termination of Certain Services and Contracts. Notwithstanding anything in this Agreement to the contrary, at or prior to the Closing, Seller shall (a) terminate, effective upon or before the Closing, any services provided to any of the Facilities by Seller or an Affiliate thereof, including the termination or severance of insurance policies with respect to coverage for any of the Facilities (subject to Section 5.10), Tax services, legal services and banking services (to include the severance of any centralized clearance accounts), other than any such services provided pursuant to an Assigned Contract or the Transition Services Agreement and (b) terminate each Contract listed on Schedule 5.6, (collectively such services or Contracts, the “Terminated Contracts”).

(a) Buyer acknowledges and agrees that as a result of the consummation of the transactions contemplated by this Agreement, it will not obtain any right, title, interest, license or other right hereunder to use Seller’s Marks, except to the extent permitted under Section 5.7(b) hereof.

(b) Buyer shall, within a reasonable period after the Closing Date not to exceed forty-five (45) days, remove Seller’s Marks from, or cover or conceal Seller’s Marks on, the Acquired Assets, including signage at the Facilities, to the extent Seller’s Marks appear on the Acquired Assets; provided that Buyer shall, within three (3) Business Days after the Closing Date, remove, cover or conceal Seller’s Marks that appear on signage at the primary entrances of the Facilities. Buyer may use Seller’s Marks prior to such removal, cover, or concealment only to the extent they appear on the Acquired Assets. Nothing herein shall be deemed to prevent Buyer from referencing Seller’s Marks as may be required by Law, including in a manner that constitutes “fair use”, or in historical, Tax, and similar records.

Section 5.8 Real Property. Buyer shall have the right, at its cost and expense, to obtain new or updated title commitments of the Owned Real Property during the Interim Period, and new title insurance policies at Closing, and Seller shall reasonably cooperate with Buyer in connection with the foregoing.

(a) Buyer or one of its Affiliates shall offer employment to each Seller Employee within forty-five (45) days after the execution of this Agreement, and in any event prior to Closing, and to each Off-Site Employee that it wishes to offer employment within sixty (60) days after the execution of this Agreement, and in any event prior to Closing. Each such offer to a Seller Employee shall include terms and provisions determined by Buyer or its Affiliate that are

consistent with the provisions of this Section 5.9 (and may be conditioned upon the occurrence of the Closing and such individual’s passage of any customary pre-employment background check and drug tests). Within sixty (60) days after the execution of this Agreement, and in any event prior to Closing, Buyer shall notify Seller as to each Seller Employee who has accepted employment with Buyer or any of its Affiliates and satisfied the applicable pre-hire requirements (each, a “Transferred Employee”), and each Seller Employee who has rejected Buyer’s offer of employment or not satisfied such requirements. Each Transferred Employee shall cease to be employed by Seller as of such Transferred Employee’s Hiring Time. Buyer shall indemnify and hold harmless Seller and its Affiliates with respect to all Liabilities arising out of Buyer’s (or any of Buyer’s Affiliates’) actions or omissions with regard to employee selection and the employment offer process described in this Section 5.9(a) (including any claim of discrimination or other illegality in such selection and offer process, and including any Liability that Seller or any of its Affiliates may incur under the U.S. Worker Adjustment and Retraining Notification Act and the regulations promulgated thereunder, or any similar state or other Law as a result of any act or omission of Buyer occurring after the Closing). The employment with Buyer or an Affiliate of Buyer of each Transferred Employee shall be effective as of the Hiring Time and shall continue for at least two years thereafter; provided, however, that on such date such Transferred Employee is actively at work or is on an active employee status (and not designated as inactive or on short-term disability leave, long-term disability leave or on other leave). With respect to each Seller Employee who fails to become a Transferred Employee as of the Closing because he or she is on inactive status (including due to any short-term disability, long-term disability or other leave), Buyer shall, or shall cause its Affiliates to, at the time such Seller Employee is ready and available to return to active employment status (so long as such date occurs within 180 days after the Closing or such additional time required by Law), provide such Seller Employee with employment in a position comparable to that which the individual had prior to the commencement of his or her absence from active employment, which employment shall continue for at least two years thereafter (the Closing or such other time each Transferred Employee otherwise begins employment with Buyer or its Affiliate, as applicable, is referred to as his or her “Hiring Time”). During the two year period commencing at Closing, Buyer shall not permit a net reduction, due to involuntary attrition, in the employment levels at each Facility below the aggregate number of Transferred Employees employed by Buyer (or Buyer’s Affiliates) immediately after the Closing. Nothing in the foregoing shall affect the right of Seller or Buyer (or Buyer’s Affiliate) to terminate the employment of a Seller Employee for cause at any time.

(b) Except with respect to (i) Seller Employees as permitted under Section 5.9(a) and (ii) Off-Site Employees, unless the other Party should agree in writing, neither Seller nor Buyer will, directly or indirectly, in any manner whatsoever, solicit for employment any officer or employee of the other Party who Seller or Buyer learned of in connection with the acquisition contemplated hereby for a period of one year after the date of this Agreement; provided, however, that this sentence shall not apply to any solicitation (or any hiring as a result of any solicitation) that consists of advertising in a newspaper or periodical of general circulation or through the Internet, which advertising is not targeted at the officers or employees of the other Party.

(c) Except as set forth on Schedule 5.9(c), effective as of their respective Hiring Times, Transferred Employees shall cease to participate in all Seller Employee Benefit Plans;

provided, however, that Seller or an Affiliate of Seller shall pay, in accordance with Seller’s or such Affiliate’s customary practice, to all Transferred Employees, all accrued salary or wages, including overtime, and all accrued incentive bonus, vacation pay or other employment benefits to which they are entitled under the Seller Benefit Plans as of their applicable Hiring Time. Neither Buyer nor any of its Affiliates shall assume or have any Liability with respect to any of the Seller Employee Benefit Plans.

(d) For the two (2) year period commencing on each Transferred Employee’s Hiring Time, Buyer or an Affiliate of Buyer shall provide such Transferred Employee with (i) a base salary or wage rate that is not less than such Transferred Employee’s base salary or wage rate that was in effect for such Transferred Employee immediately prior to such Transferred Employee’s Hiring Time, and (ii) benefits and other compensation that are at least as favorable in the aggregate as the benefits and other compensation provided to such Transferred Employee immediately prior to such Transferred Employee’s Hiring Time. Notwithstanding the foregoing, Buyer shall cause, or with respect to subsection (B) use commercially reasonable efforts to cause, each Transferred Employee and his or her eligible dependents (including all such Transferred Employee’s dependents) covered immediately prior to the Closing by a group health plan maintained by Seller or an Affiliate of Seller to be covered under a group health plan maintained by Buyer or an Affiliate of Buyer that (A) provides major medical and dental benefits coverages to the Transferred Employee and such eligible dependents effective immediately upon the Hiring Time and (B) credits such Transferred Employee, for the year during which such coverage under such group health plan begins, with any deductibles and co-payments already incurred during such year under a group health plan maintained by Seller or an Affiliate of Seller; provided, however, that for purposes of applying this clause (B) with respect to any Transferred Employee, the Transferred Employee shall be responsible for providing the necessary information to Buyer based on explanation of benefit forms received by the Transferred Employee from the group health plan maintained by Seller or an Affiliate of Seller. Buyer or an Affiliate of Buyer shall recognize each Transferred Employee’s years of company service prior to the applicable Hiring Time with Seller and its Affiliates for purposes of vesting or other benefit/coverage eligibility (including eligibility for retiree benefits/coverages), benefit accrual (with the exception of benefits accrued pursuant to any Buyer or Buyer Affiliate “defined benefit pension plan” as defined in ERISA Section 3(35)), and benefit determination under all employee benefit and compensation plans and programs maintained after the applicable Hiring Time by Buyer or an Affiliate of Buyer in which such Transferred Employee is permitted to participate, including paid vacation, paid sick time and severance benefits. Buyer shall cause each employee welfare benefit plan or program sponsored by Buyer or an Affiliate of Buyer that the Transferred Employees may be eligible to participate in on or after the Closing to waive any preexisting condition exclusion or restriction with respect to participation and coverage requirements applicable to Transferred Employees. Nothing in the foregoing shall affect the right of Buyer or its Affiliate to terminate the employment of a Transferred Employee for cause at any time, and notwithstanding the foregoing, Buyer shall thereafter have no obligation with respect to any payments, compensation or benefits to such terminated Transferred Employee except as otherwise required by Law.

(e) Claims of Transferred Employees and their eligible beneficiaries and dependents for medical, dental, prescription drug, life insurance or other welfare benefits (“Welfare Benefits”) (other than disability benefits) that are incurred before a Transferred Employee’s

Buyer and Seller shall each take commercially reasonable steps and make all necessary filings in order to minimize such Transfer Taxes. Prior to Buyer filing all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, Buyer shall provide such Tax Returns to Seller and Seller shall have up to ten (10) Business Days to review and comment on such Tax Returns.

No later than ten (10) Business Days prior to the due date of any such Tax Return, Buyer shall make such Tax Return available for Seller’s review and comment. Buyer shall respond no later than five (5) Business Days prior to the due date for filing such Tax Return. Without the prior written consent of Seller, Buyer will not (i) file or amend any Tax Return relating to a taxable period (or portion thereof) ending on or prior to the Closing Date or (ii) extend or waive, or cause to be extended or waived, any statute of limitations or other period for the assessment of any Tax or deficiency related to a taxable period (or portion thereof) ending on or prior to the Closing Date; provided, however, that Buyer may amend any such return if Buyer agrees not to seek indemnity from Seller for, and to indemnify and hold Seller harmless against, any Taxes or Losses attributable to such amended return.

(b) Whenever any Taxing Authority asserts a claim, makes an assessment, or otherwise disputes the amount of Taxes relating to a taxable period (or portion thereof) ending on or before the Closing Date, Buyer shall, upon receipt of such assertion, promptly, but no later than thirty (30) days thereafter, inform Seller in writing of such assertion. With respect to proceedings that relate solely to Taxes that the Buyer acknowledges in writing represent Excluded Liabilities, Seller shall have the sole right to control any such proceedings and to determine whether and when to settle any such claim, assessment or dispute; provided, however, that Seller shall not settle any Tax controversies in a manner that would reasonably be expected to affect the Tax liabilities of Buyer or any of its Affiliates in a material manner for any taxable year or period ending after the Closing Date without the prior written consent of Buyer. With respect to proceedings that relate to Taxes for which the Buyer does not acknowledge in writing represent Excluded Liabilities, Buyer shall have the sole right to control any such proceedings and determine whether and when to settle any such claim, assessment or dispute; provided, however, that Buyer shall not settle any Tax controversies in a manner that would reasonably be expected to affect the Tax liabilities of Seller or any of its Affiliates in a material manner for any taxable year or period without the prior written consent of Seller. Each of Buyer and Seller shall provide the other with such assistance and cooperation as may reasonably be requested by the other Party in connection with the preparation of any Tax Return, any audit or other examination by any Taxing Authority, or any judicial or administrative proceedings relating to liability for Taxes. Such assistance and cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and each will retain and provide the requesting Party with any records or information until the expiration of the statute of limitations (and, to the extent notified by the other Party, any extensions thereof) of the respective taxable periods which may be relevant to such Tax Return, audit or examination, proceedings or determination.

Section 5.13 Casualty. If any Acquired Asset is damaged or destroyed by a casualty loss after the Effective Date and prior to the Closing (a “Casualty Loss”), and the cost of restoring such damaged or destroyed Acquired Asset to a condition reasonably comparable to its prior condition, (such costs with respect to any Acquired Asset, the “Casualty Cost”) is greater than $1,500,000 but less than or equal to 20% of the Base Purchase Price, Seller shall elect, by notice to Buyer provided within fifteen (15) days of the applicable Casualty Loss, to either (i) reduce the amount of the Purchase Price by the estimated Restoration Cost (as estimated by a qualified firm mutually selected by Buyer and Seller promptly after the date of the event giving rise to the Casualty Loss) or (ii) restore such damaged or destroyed Acquired Asset at Seller’s expense prior to Closing to a condition reasonably comparable to its condition prior to such Casualty Loss, and in either event such Casualty Loss shall not affect the Closing. If the aggregate Casualty Cost associated with all Casualty Losses is greater than 20% of the Base Purchase Price, then either Buyer or Seller may terminate this Agreement pursuant to Section 8.1(e) hereof. If the Casualty Cost is equal to or less than $1,500,000 of the Base Purchase Price, (x) neither Buyer nor Seller shall have the right or option to terminate this Agreement and (y) there shall be no reduction in the amount of the Purchase Price. To the extent Seller elects to reduce the amount of the Purchase Price by the estimated Restoration Cost pursuant to this Section 5.13, Buyer will, at Seller’s written election, assign to Seller the rights if any, to any contribution available under any long term service agreement, as and to the extent relating to the

applicable Casualty Loss. “Restoration Cost” means, with respect to a Casualty Loss, the sum of (a) the Casualty Cost with respect to such Casualty Loss, plus (b) the amount of gross margin with respect to such Casualty Loss; in each case arising after the Closing Date and as determined by a qualified firm mutually selected by Buyer and Seller promptly after the date of the event giving rise to such Casualty Loss, which firm shall take into account, among other things, a reasonable period that the firm estimates the damaged or destroyed Acquired Assets will remain unrestored under Good Utility Practice.

Section 5.14 Condemnation. If any Acquired Asset is taken by condemnation after the date hereof and prior to the Closing and such Acquired Asset has a Condemnation Value which is greater than $1,500,000 but less than or equal to 20% of the Base Purchase Price, Seller shall elect by written notice to Buyer provided within fifteen (15) days of the applicable condemnation event (and in any event at least ten (10) days prior to the Closing Date) to reduce the Purchase Price by such Condemnation Value and such condemnation shall not affect the Closing. If the aggregate Condemnation Values associated with all such condemnation events is greater than 20% of the Base Purchase Price, either Buyer or Seller may terminate this Agreement pursuant to Section 8.1(e) hereof. If the Condemnation Value is equal to or less than $1,500,000 of the Base Purchase Price, (x) neither Buyer nor Seller shall have the right or option to terminate this Agreement, and (y) there shall be no reduction in the amount of the Purchase Price. “Condemnation Value” shall mean an amount equal to the condemnation award value of the affected Acquired Asset plus, if not otherwise included in the condemnation award value, the amount of any gross margin with respect to such affected Acquired Assets which results from such condemnation, with such gross margin determined by a qualified firm mutually selected by Buyer and Seller promptly after the date of the event giving rise to such condemnation.

(a) Any information or materials furnished by Seller or any of its Affiliates to Buyer on and after the date of this Agreement and prior to Closing shall be subject to the Confidentiality Agreement; provided that Buyer shall not have any obligation to maintain the confidentiality of information with respect to the Acquired Assets from and after the Closing. Notwithstanding the foregoing, Buyer and its Affiliates shall be entitled to disclose Confidential Information to investors and limited partners, and to prospective investors or other Persons as part of fundraising, financing or marketing activities undertaken by Buyer or its Affiliates, provided such disclosures are made to Persons subject to an obligation of confidentiality with respect to such information. Effective upon Closing, the Parties shall cause the Confidentiality Agreement to be terminated. In the event of any conflict between this Agreement and the Confidentiality Agreement, this Agreement shall prevail.

(b) Either Party may provide Confidential Information to any Governmental Authority with jurisdiction as necessary to comply with Section 5.2. To the extent permitted by Law, the disclosing Party shall exercise commercially reasonable efforts to seek confidential treatment for the Confidential Information provided to any Governmental Authority and the disclosing Party shall notify the other Party as far in advance as is practicable and lawful of its intention to release to any Governmental Authority any Confidential Information.

(c) From and after Closing, Seller shall, and shall cause its Affiliates to, maintain in confidence and not disclose to any Person any Confidential Information (except for Confidential Information relating exclusively to Seller and its Affiliates, and not to any of the Acquired Assets or Assumed Liabilities) or any non-public information relating to Buyer or its Affiliates provided in connection herewith, except as and to the extent required by Law or this Agreement or any of the Ancillary Agreements.

With respect to any Coal Support Obligation that remains outstanding after the Closing Date (until such time as such Coal Support Obligation is terminated or substituted in accordance herewith, an “Outstanding Coal Support Obligation”), (a) Buyer shall continue to use its commercially reasonable efforts to terminate, or cause Buyer to be substituted in all respects for Seller and any of its Affiliates in respect of, all obligations of Seller or any of its Affiliates under such Outstanding Coal Support Obligations; (b) Buyer shall not renew, amend or extend the terms of (in any manner that increases or extends or otherwise adversely

changes the obligations of Seller or any of Seller’s Affiliates under) any Contract or other obligation for which Seller or any of its Affiliates is or would reasonably be expected to be liable under, any such Outstanding Coal Support Obligations unless Seller and all of Seller’s Affiliates are completely released from all Support Obligations and other liability under such Contracts; and (c) Seller shall and, if applicable, shall cause its Affiliates to, maintain each such Outstanding Coal Support Obligation until (1) its termination in accordance with its terms, (2) substitution has been effected or (3) its termination in accordance with the immediately succeeding sentence. After Closing, if a draw occurs under an Outstanding Coal Support Obligation as the result of an event of default by Buyer or its Affiliates, and Seller (or Seller’s Affiliate, as applicable) pays an amount equal to or greater than $500,000 in connection therewith, then Seller (or Seller’s Affiliate, as applicable) shall be entitled to terminate such Outstanding Coal Support Obligation upon at least five (5) Business Days’ prior written notice to Buyer; provided, that all applicable notice and cure periods under the Contract to which such Outstanding Coal Support Obligation relates shall have expired; provided further, that Buyer shall not have reimbursed Seller (or Seller’s Affiliate, as applicable) for such payment.

(c) Upon termination of this Agreement by either Party for any reason, each Party shall return or destroy, in accordance with and to the extent required by the terms of the Confidentiality Agreement, all Confidential Information and all other documents and other materials of any other Party relating to the Acquired Assets, the Facilities, the Sites, Seller or this Agreement and the transactions contemplated hereby, including any information relating to the Parties and to this Agreement, whether obtained before or after the execution of this Agreement (collectively, the “Transaction Materials”) and all Transaction Materials received by Buyer with respect to the Acquired Assets, the Facilities, the Sites or Seller shall remain subject to the Confidentiality Agreement; provided, that if any action, lawsuit or claim is initiated or filed within one year after the date of this Agreement by a Party with respect to the termination of this Agreement pursuant to this Article XIII, the Parties shall not be required to return or destroy the Transaction Materials pursuant to this Section 8.2(c) or the Confidentiality Agreement until such action, lawsuit or claim is resolved, dismissed or withdrawn.

Section 8.3 Specific Performance and Other Remedies. Each Party hereby acknowledges that the rights of each Party to consummate the transactions contemplated hereby are special, unique and of extraordinary character and that, if any Party violates or fails or refuses to perform any covenant or agreement made by it herein, the non-breaching Party may be without an adequate remedy at law. If any Party violates or fails or refuses to perform any covenant or agreement made by such Party herein, the non-breaching Party or Parties may, subject to the terms hereof and in addition to any remedy at law for damages or other relief, institute and prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief.

(a) If this Agreement is validly terminated by Seller pursuant to Section 8.1(b) or by Buyer pursuant to Section 8.1(g), then in lieu of all other Claims and remedies that might otherwise be available with respect thereto, including elsewhere under this Agreement and notwithstanding any other provision of this Agreement, Buyer hereby agrees to pay immediately to Seller, as liquidated damages in connection with such termination, an amount in immediately available funds equal to (i) $40,000,000 minus (ii) all amounts (if any) paid by or on behalf of Buyer to Seller prior to termination of this Agreement with respect to any Claim brought under or with respect to this Agreement or the transactions contemplated hereby.

(b) The provisions for payment of liquidated damages in this Section 8.4 have been included because, in the event of termination of this Agreement as described in Section 8.4(a), the actual damages to be incurred by Seller are reasonably expected to approximate the amount of liquidated damages set forth in this Section 8.4 and because the actual amount of such damages would be difficult if not impossible to measure precisely. Buyer and Seller further agree that if Buyer is or becomes obligated to pay a fee pursuant to Section 8.4(a), the right to receive such fee shall be the sole and exclusive remedy of Seller against Buyer, its Affiliates and their respective Representatives with respect to any and all matters arising from or relating to the Acquired Assets, this Agreement and/or the transactions contemplated hereby except with respect to fraud.

(a) Subject to Section 9.2, from and after the Closing, Seller shall indemnify, defend and hold harmless Buyer, its Affiliates and each of their respective Representatives (collectively, the “Buyer Indemnified Parties”) from and against all Losses incurred or suffered by any Buyer Indemnified Party resulting from:

(i) any breach of any representation or warranty of Seller contained in this Agreement or in the certificate delivered pursuant to Section 6.3;

(ii) any breach of any covenant or agreement of Seller contained in this Agreement;

(iv) any Claim or Loss relating to the assets that are the subject of the Solar Facility License Agreement (excluding any Claim or Loss with respect to any failure by Buyer to perform under the Solar Facility License Agreement).

(b) Subject to Section 9.2, from and after Closing, Buyer shall, except, in each case for, and solely to the extent of, Losses that are otherwise subject to indemnification by Seller pursuant to Section 9.1(a), indemnify, defend and hold Seller, its Affiliates and each of their respective Representatives (collectively, the “Seller Indemnified Parties”) harmless from and against all Losses incurred or suffered by any Seller Indemnified Party resulting from:

(i) any breach of any representation or warranty of Buyer contained in this Agreement or in the certificate delivered pursuant to Section 7.3;

(ii) any breach of any covenant or agreement of Buyer contained in this Agreement;

(iv) any Taxes that are the responsibility of Buyer pursuant to Section 2.10 or Section 5.11 of this Agreement, or that are attributable to taxable periods beginning after the Closing Date; and

(v) any Claim or Loss relating to, or any draw upon, any Outstanding Coal Support Obligation.

Section 9.2 Limitations of Liability. Notwithstanding anything in this Agreement to the contrary:

(a) the representations and warranties of Seller set forth in Article III (other than (i) the Designated Representations, which shall survive the Closing indefinitely, (ii) the

representations and warranties set forth in Section 3.11 (Taxes), which shall survive the Closing until sixty (60) days following the expiration of the applicable statute of limitations, (iii) the representations and warranties set forth in Section 3.15 (Environmental Matters), which shall survive the Closing for a period of four (4) years, and (iv) the representations and warranties of Buyer set forth in Article IV (other than the Designated Representations, which shall survive the Closing indefinitely)) shall survive the Closing for a period of eighteen (18) months. The covenants of the Parties contained in this Agreement that are to be performed prior to the Closing shall survive the Closing for a period of twelve (12) months, and the covenants of the Parties contained in this Agreement that are to be performed subsequent to the Closing shall terminate at the expiration of the applicable statute of limitations;

(b) Seller shall have no Liability for a breach of any representation or warranty contained in this Agreement until the aggregate amount of all Losses incurred by the Buyer Indemnified Parties (excluding all Losses arising out of or relating to Liabilities described in clause (ii) of this Section 9.2(b)) equals or exceeds the Deductible Amount, in which event Seller shall be liable for Losses only to the extent they are in excess of the Deductible Amount; provided that (i) the Deductible Amount shall not apply to any Losses relating to an Excluded Liability, a breach of a representation or warranty set forth in Section 3.11 (Taxes) or any Designated Representation, and (ii) in no event shall Seller have any Liability for any breach of a representation or warranty in this Agreement (other than those relating to an Excluded Liability, Taxes or any breach of any Designated Representation) in connection with any single item or group of related items that results in Losses, in any such case, of less than $175,000;

(c) in no event shall Seller’s aggregate Liability arising out of or relating to any breach of any representation or warranty of Seller in this Agreement (other than any representation or warranty set forth in Section 3.11 (Taxes), which shall not be subject to a cap), whether based on contract, tort, strict liability, other Laws or otherwise, exceed (i) 20% of the Base Purchase Price with respect to a breach of any representation or warranty except as set forth in subclause (ii) of this Section 9.2(c), or (ii) exceed 100% of the Base Purchase Price with respect to a breach of any Designated Representation;

(d) any Indemnified Party that becomes aware of a Loss for which it seeks indemnification under this Article IX shall be required to use commercially reasonable efforts to mitigate the Loss;

(e) references to “Material Adverse Effect” or other materiality qualifications (or correlative terms) shall, except with respect to Section 3.21, be disregarded for all purposes of the provisions of Section 9.1;

(f) the Losses suffered by any Indemnified Party shall be calculated after giving effect to any amounts actually received by such Indemnified Party at or prior to the time of calculation in respect thereof, including insurance proceeds (net of the reasonable third party out of pocket costs and expenses associated with such recoveries and any associated increases in insurance premiums) and any associated tax benefits to Buyer (it being understood and agreed that the Indemnified Party shall use its commercially reasonable efforts to seek insurance recoveries in respect of Losses to be indemnified hereunder). If any insurance proceeds or other recoveries from third parties are actually realized (net of the reasonable third party out of pocket

costs and expenses associated with such recoveries and any associated increases in insurance premiums) by an Indemnified Party subsequent to the receipt by such Indemnified Party of an indemnification payment hereunder in respect of the claims to which such insurance proceedings or third party recoveries relate, the Indemnified Party shall promptly notify the Indemnifying Party of such receipt and appropriate refunds shall be made promptly to the Indemnifying Party regarding the amount of such indemnification payment;

(g) Losses to any Indemnified Party hereunder shall be determined net of (i) any Tax benefit actually realized by the time of such determination, and (ii) the net present value of Tax benefits reasonably expected to be derived by the Party being indemnified as a result of sustaining such Losses;

(h) unless otherwise required by applicable Law, any indemnity payment made pursuant to this Agreement will be treated as an adjustment to the Purchase Price for all Tax purposes;

(i) in valuing any Loss, no adjustment shall be made as a result of any multiple, increase factor, or any other premium over fair market value, book or historical value which may have been paid by Buyer for the Acquired Assets whether or not such multiple, increase factor or other premium had been used by Buyer at the time of, or in connection with, calculating or preparing its bid, its proposed purchase price for the Acquired Assets or its final purchase price for the Acquired Assets;

(j) any Indemnified Party that becomes aware of a Loss for which it seeks indemnification under this Article IX shall promptly (and, in any event, within thirty (30) days of becoming aware of such Loss) notify the Indemnifying Party in writing of the basis for such Loss, setting forth the nature of such Loss in reasonable detail; the failure of an Indemnified Party to so notify the Indemnifying Party shall not relieve the Indemnifying Party of liability hereunder except to the extent that the cost of providing indemnification for such Loss is actually prejudiced by the failure to give such notice; provided, however, that no Indemnifying Party shall have any obligation to indemnify an Indemnified Party with respect to a Loss unless, prior to the expiration of the applicable survival period set forth in Section 9.2(a), the Indemnified Party shall have notified the Indemnifying Party in writing of the basis for such Loss, setting forth the nature of such Loss in reasonable detail;

(k) notwithstanding anything to the contrary herein, the limitation, covenants, agreements and obligations set forth in Section 9.2 shall not apply to Seller’s indemnification obligations pursuant to Section 9.1(a)(iii), or any representation or warranty set forth in Section 3.11(Taxes) and any breach of any covenant, agreement or obligation in this Agreement.;

(l) from and after Closing, Seller shall have no right of contribution from any of the Acquired Assets with respect to any breach of a representation, warranty, covenant or agreement of Seller in this Agreement or any Ancillary Agreement;

(m) For Tax purposes, any indemnity payments made pursuant to this Article IX shall be treated as an adjustment to the purchase price of the Acquired Assets and Acquired Entity; and

(n) Seller shall have no liability for any Claim against Buyer or its Affiliates with respect to any breach of the representations set forth in Sections 3.15(a) and (d) and any Excluded Liability set forth in Sections 2.4(f), (g) and (h) if and to the extent any such Claim arose as the result of a notification made by Buyer or its Affiliates to any Person, including any Governmental Authority; provided that the limitation on Seller’s liability set forth in this Section 9.2(n) shall not apply where (i) such notification was (A) required by Law, (B) reasonably required to avoid or mitigate an imminent and substantial endangerment to human health or the environment, or (C) consistent with Good Utility Practice; and (ii) Buyer provides, or causes to be provided, to Seller advance notice of such notification. To the extent permitted by, and subject in all respects to, the provisions of Section 9.4, if, as the result of any such notification, Buyer becomes subject to a Claim and Buyer believes it has a claim for indemnification against Seller under Section 9.1(a) as a result, then (1) Buyer shall promptly notify Seller in writing of the basis for such claim setting forth the nature of the Claim in reasonable detail, and (2) Seller shall be entitled to participate in the Claim and, to the extent that it wishes, to assume the defense of such Claim.

(a) From and after Closing, the rights and remedies of the Parties under this Article IX are, except in the case of fraud, exclusive and in lieu of any and all other rights and remedies which the Parties may have under this Agreement or otherwise, including with respect to: (i) any breach of any representation or warranty set forth in this Agreement, (ii) any breach or failure to perform any covenant or agreement set forth in this Agreement or (iii) the Assumed Liabilities or the Excluded Liabilities, as the case may be. Without limiting the foregoing, with respect to the Acquired Assets, Buyer, for itself and its Affiliates, does, effective as of Closing, hereby irrevocably release, hold harmless and forever discharge Seller and its Affiliates from any and all Environmental Claims (other than those Environmental Claims for which Seller is obligated to indemnify Buyer pursuant to this Article IX) related to or arising from the Acquired Assets. In furtherance of the foregoing, Buyer, for itself and on behalf of its Representatives, hereby, effective as of Closing, irrevocably waives any and all rights and benefits with respect to such Environmental Claims (other than those Environmental Claims for which Seller is obligated to indemnify Buyer pursuant to this Article IX) 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 9.3(a) 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 and its Affiliates from all such Environmental Claims (other than those Environmental Claims for which Seller is obligated to indemnify Buyer pursuant to this Article IX).

(b) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY,

INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES OR LOST PROFITS (EXCEPT FOR AS EXPRESSLY PROVIDED IN SECTIONS 5.13 AND 5.14 AND EXCEPT FOR ANY LOST PROFITS THAT ARE DIRECT DAMAGES) WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT (“NON-REIMBURSABLE DAMAGES”), PROVIDED, THAT ANY AMOUNTS PAYABLE TO THIRD PARTIES PURSUANT TO A THIRD-PARTY CLAIM SHALL NOT BE DEEMED NON-REIMBURSABLE DAMAGES.

(a) If any Party becomes subject to a pending or threatened Claim of a third party and such Party (the “Claiming Party”) believes it has a claim against the other Party (the “Responding Party”) as a result, then the Claiming Party shall promptly notify the Responding Party in writing of the basis for such Claim setting forth the nature of the Claim in reasonable detail. The failure of the Claiming Party to so notify the Responding Party shall not relieve the Responding Party of liability hereunder except to the extent that the defense of such Claim is actually prejudiced by the failure to give such notice.

(b) If any proceeding is brought by a third party against a Claiming Party and the Claiming Party gives notice to the Responding Party pursuant to this Section 9.4, the Responding Party shall be entitled to participate in such proceeding and, to the extent that it wishes, to assume the defense of such proceeding, if (i) the Responding Party provides written notice to the Claiming Party that the Responding Party intends to undertake such defense, (ii) the Responding Party conducts the defense of the third-party Claim actively and diligently with counsel reasonably satisfactory to the Claiming Party, and (iii) if the Responding Party is a party to the proceeding, the Responding Party or the Claiming Party has not reasonably determined in good faith that joint representation would be inappropriate because of a conflict of interest. The Claiming Party, in its sole discretion, shall have the right to employ separate counsel in any such action and to participate in the defense thereof, and, except where there is a conflict of interest that makes it inappropriate for the same counsel to represent both the Claiming Party and the Responding Party, the fees and expenses of such counsel shall be paid by such Claiming Party. The Claiming Party and the Responding Party shall fully cooperate with each other and their respective counsel in the defense or compromise of such Claim. No compromise or settlement of such Claims may be effected by the Responding Party without the Claiming Party’s consent unless (x) there is no finding or admission of any violation of Law or any violation of the rights of any Person and no adverse effect on any other Claims that may be made against the Claiming Party, (y) the sole relief provided is monetary damages that are paid in full by the Responding Party, and (z) the third party who brought the Claim against the Claiming Party executes a full release of such Claim with respect to the Claiming Party and its Affiliates.

(c) If (i) notice is given to the Responding Party of the commencement of any third-party legal proceeding and the Responding Party does not, within thirty (30) days after the Claiming Party’s notice is given, give written notice to the Claiming Party of its election to assume the defense of such legal proceeding, (ii) the conditions set forth in clause (ii) of Section 9.4(b) above become unsatisfied, or (iii) the Claiming Party determines in good faith that there is

a reasonable probability that a legal proceeding may adversely affect it other than as a result of monetary damages for which it would be entitled to indemnification from the Responding Party under this Agreement, then the Claiming Party shall (upon written notice to the Responding Party) have the right to undertake the defense, compromise or settlement of such claim; provided, however, that the Responding Party shall remain otherwise responsible for any liability with respect to amounts arising from or related to such third-party claim, including fees and expenses of counsel, to the extent it is ultimately determined that such Responding Party is liable with respect to such third-party claim under this Agreement. The Responding Party may elect to participate in such legal proceedings, negotiations or defense at any time at its own expense.

(a) Unless this Agreement specifically requires otherwise, any notice, demand or request provided for in this Agreement, or served, given or made in connection with it, shall be in writing and shall be deemed properly served, given or made if delivered in person or sent by facsimile, or sent by registered or certified mail, postage prepaid, or by a nationally recognized overnight courier service that provides a receipt of delivery, in each case, to the Parties, or with respect to Article XI, the Guarantor, at the addresses specified below:

(b) Notice given by personal delivery, mail or overnight courier pursuant to this Section 10.1 shall be effective upon physical receipt. Notice given by facsimile pursuant to this Section 10.1 shall be effective as of the date of confirmed delivery if delivered before 5:00 p.m. Eastern Time on any Business Day or the next succeeding Business Day if confirmed delivery is after 5:00 p.m. Eastern Time on any Business Day or during any non-Business Day. Each Party and the Guarantor may change the address by which proper notice shall be given pursuant to this Section 10.1 by providing notice to the other Party in accordance with this Section.

Section 10.2 Entire Agreement. This Agreement (including the Exhibits and Schedules hereto), together with the Ancillary Agreements and, prior to Closing the Confidentiality Agreement constitute the entire agreement between the Parties and/or the Guarantor and supersede any prior understandings, agreements, or representations by or between the Parties and/or the Guarantor, written or oral, with respect to the subject matter hereof.

Section 10.3 Expenses. Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated hereby are consummated, each Party and the Guarantor will pay its own costs and expenses incurred in anticipation of, relating to and in connection with the negotiation and execution of this Agreement and the transactions contemplated hereby, including all expenses and costs incurred to obtain approvals required by such Party from Governmental Authorities.

Section 10.4 Disclosure. Seller may, at its option, include in the Schedules items that are not material in order to avoid any misunderstanding, and any such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgment or representation that such items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement. Information disclosed in any Schedule shall constitute a disclosure for purposes of all other Schedules notwithstanding the lack of specific cross-reference thereto, but only to the extent the applicability of such disclosure to such other Schedule is reasonably apparent on its face. In no event shall the inclusion of any matter in the Schedules be deemed or interpreted to broaden Seller’s representations, warranties, covenants or agreements contained in this Agreement. The mere inclusion of an item in the Schedules shall not be deemed an admission by Seller that such item represents a material exception or fact, event, or circumstance or that such item is reasonably likely to result in a

Material Adverse Effect. The Parties shall promptly notify each other upon becoming aware of (a) the occurrence, or failure to occur, of any event, which occurrence or failure has caused any representation or warranty of such Party contained in this Agreement or in any exhibit, schedule, certificate, document or written instrument attached hereto to be untrue or inaccurate, (b) any failure of such Party to comply with, perform or satisfy, in any respect, any covenant, condition or agreement to be complied with, performed by or satisfied by it under this Agreement or any exhibit, schedule, certificate, document or written instrument attached hereto and (c) except as otherwise provided in this Agreement, any notice or other communication from any Governmental Authority in connection with this Agreement or the transactions contemplated herein; provided, that such disclosure shall not be deemed to cure, or to relieve any Party of any liability or obligation with respect to, any breach of or failure to satisfy any representation, warranty, covenant or agreement or any condition hereunder, and shall not affect any Party’s right with respect to indemnification hereunder.

Section 10.5 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. All remedies, either under this Agreement or by Law or otherwise afforded, will be cumulative and not alternative.

Section 10.6 Amendment. This Agreement may be amended, supplemented or modified only by a written instrument duly executed by or on behalf of each Party (and, solely with respect to amendments, supplements or modifications to Article XI, also by the Guarantor).

Section 10.7 No Third Party Beneficiary. Except for the provisions of Section 5.3(c) (which are intended for the benefit of the Persons identified therein), the terms and provisions of this Agreement are intended solely for the benefit of the Parties and their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person, including any employee, any beneficiary or dependents thereof, or any collective bargaining representative thereof.

Section 10.8 Assignment; Binding Effect. Buyer shall have the right to assign to any one or more of its Affiliates any of its rights or obligations under this Agreement, any Ancillary Agreement or any other document or instrument, in whole or in part (including the right to acquire any of the Acquired Assets); provided, however, that no assignment hereunder shall relieve Buyer of its obligations under this Agreement and Buyer shall cause such assignees to perform such obligations on behalf of Buyer in accordance with the terms of this Agreement. Buyer may assign its rights to indemnification under this Agreement to Buyer’s lenders for collateral security purposes, but such assignment shall not release Buyer from its obligations hereunder. Except as provided in the preceding sentences, neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party without the prior written consent of the other Party or by the Guarantor without the prior written consent of the Buyer, and in each case any attempt to do so will be void, except for assignments and transfers by operation of Law. Subject to this Section 10.8, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties and their respective successors and permitted assigns.

Section 10.9 Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions hereof.

Section 10.10 Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations of any Party or the Guarantor under this Agreement will not be materially and adversely affected thereby, such provision will be fully severable, this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom and in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

Section 10.11 Counterparts; Facsimile. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a facsimile machine or by .pdf, .tif, .gif, .peg or similar attachment to electronic mail shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.

Section 10.12 Bulk Sales. Each Party hereby waives compliance by the other Party with the provision of any bulk sales or transfer laws of any jurisdiction in connection with the transactions contemplated by this Agreement.

(a) This Agreement shall be governed by and construed in accordance with the Laws of the State of New York, without giving effect to any conflict or choice of law provision that would result in the imposition of another state’s Law, provided that any dispute relating to real property shall be governed by, and construed in accordance with, the laws of the State of Maryland.

(b) THE PARTIES AND THE GUARANTOR HEREBY IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT IN NEW YORK, NEW YORK IN CONNECTION WITH ANY ACTION, SUIT OR PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT (INCLUDING ARTICLE XI), AND EACH PARTY AND THE GUARANTOR HEREBY CONSENTS TO THE JURISDICTION OF SUCH COURTS (AND OF THE APPROPRIATE APPELLATE COURTS THEREFROM) IN ANY SUCH SUIT, ACTION OR PROCEEDING AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT ANY SUCH SUIT, ACTION OR PROCEEDING THAT IS BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. DURING THE PERIOD A LEGAL DISPUTE THAT IS FILED IN ACCORDANCE WITH THIS SECTION 10.13 IS

PENDING BEFORE A COURT, ALL ACTIONS, SUITS OR PROCEEDINGS WITH RESPECT TO SUCH LEGAL DISPUTE OR ANY OTHER LEGAL DISPUTE BETWEEN THE PARTIES AND RELATING TO THE TRANSACTIONS CONTEMPLATED HEREBY, INCLUDING ANY COUNTERCLAIM, CROSS-CLAIM OR INTERPLEADER, SHALL BE SUBJECT TO THE EXCLUSIVE JURISDICTION OF SUCH COURT. EACH PARTY AND THE GUARANTOR HEREBY WAIVES, AND SHALL NOT ASSERT AS A DEFENSE IN ANY LEGAL DISPUTE BROUGHT IN CONNECTION WITH THIS AGREEMENT, THAT (A) SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT IN SUCH COURT, (B) SUCH ACTION, SUIT OR PROCEEDING IS BROUGHT IN AN INCONVENIENT FORUM OR (C) THE VENUE OF SUCH ACTION, SUIT OR PROCEEDING IS IMPROPER. EACH PARTY AGREES TO ACCEPT SERVICE OF PROCESS OUT OF ANY OF THE ABOVEMENTIONED COURTS IN ANY SUCH ACTION, SUIT OR PROCEEDING BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH PARTY AT THE ADDRESS SET FORTH IN SECTION 10.1. A FINAL JUDGMENT IN ANY ACTION, SUIT OR PROCEEDING DESCRIBED IN THIS SECTION 10.13 FOLLOWING THE EXPIRATION OF ANY PERIOD PERMITTED FOR APPEAL AND SUBJECT TO ANY STAY DURING APPEAL SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY APPLICABLE LAWS.

(c) EACH PARTY AND THE GUARANTOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY.

Section 10.14 Attorneys’ Fees. If either Party shall bring an action to enforce the provisions of this Agreement, the prevailing Party shall be entitled to recover its reasonable attorneys’ fees and expenses incurred in such action from the non-prevailing Party.

Section 11.1 Guaranty. The Guarantor hereby absolutely and unconditionally guarantees to Buyer the timely payment and performance of the obligations of Seller under this Agreement (“Guaranteed Obligations”), provided that, notwithstanding anything contained in this Article XI or otherwise, in no event (a) shall Guarantor’s aggregate Liability in respect of any breach by Seller of the covenant set forth in Section 5.26 exceed $40,000,000, nor shall Guarantor have any Liability in respect of the any breach by Seller of the covenant set forth in Section 5.26 after December 31, 2015, and (b) shall Guarantor’s aggregate Liability in respect of all other Guaranteed Obligations exceed twenty percent (20%) of the Base Purchase Price, nor shall Guarantor have any Liability in respect of such other Guaranteed Obligations after the eighteen (18) month anniversary of the Closing Date (December 31, 2015 or the eighteen (18) month anniversary of the Closing Date, as applicable, the “Guaranty Expiration Date”); provided that notwithstanding the foregoing, if any claim has been made by Buyer under this Article XI on or before the applicable Guaranty Expiration Date and such claim has not been fully and finally resolved, then the provisions of this Article XI shall survive with respect to such claim until the date that such claim is finally resolved.

Section 11.2 Effect of Amendments. The Guarantor agrees that Seller may modify, amend and supplement this Agreement and/or any Ancillary Agreement and may delay or extend the Closing Date or the date on which any payment must be made pursuant to such Agreement or delay or extend the date on which any act must be performed by Seller or any other Person, as applicable, thereunder, all without notice to or further assent by the Guarantor, who shall remain bound by the provisions of this Article XI, notwithstanding any such act.

Section 11.3 Waiver of Rights. The Guarantor hereby waives all suretyship defenses and all defenses with respect to the Guaranteed Obligations of promptness, diligence, presentment, demand for payment or performance, protest, notice of dishonor, notice of default, notice of acceptance, and all other notices, demands or conditions whatsoever. Except to the extent set forth in Section 11.1, the obligations of Guarantor under this Agreement are a continuing, absolute, irrevocable and unconditional guaranty by the Guarantor of the Guaranteed Obligations. The Guarantor’s obligations hereunder shall remain in full force and effect, shall not be affected, impaired, reduced or modified, and the Guarantor shall have no right to terminate its obligations under this Agreement or to be released, relieved or discharged, in whole or in part, from its payment and performance obligations by reason of the following, all of which the Guarantor hereby waives: (a) any bankruptcy, reorganization, or insolvency under any Law applicable to Seller or any other Person (other than Guarantor), or by any action of a trustee in any such proceeding; (b) any amendment, supplement, modification, waiver, adjustment, compromise, or release of, or any failure to exercise any right, remedy, power or privilege under or in respect of, the Guaranteed Obligations or this Agreement; (c) any merger or consolidation of Seller, Buyer or the Guarantor into or with any other Person or any change in form of organization, name, membership or ownership of Seller, Buyer or Guarantor; (d) any lack of genuineness, validity, legality, enforceability or value of the Guaranteed Obligations or this Agreement; (e) the permitted assignment or transfer of all or any part of this Agreement; and (f) to the extent permitted by Law, any other event, circumstance, act or omission whatsoever which might constitute a legal or equitable discharge of a surety or guarantor.

Section 11.4 Settlements Conditional. Notwithstanding anything to the contrary in this Agreement, including Article XI, if any monies paid by or on behalf of Seller under this Article XI in reduction of the obligations of Seller under this Agreement have to be repaid or rescinded or must otherwise be restored by virtue of any provision or enactment relating to bankruptcy, insolvency, liquidation or otherwise for the time being in force, the liability of the Guarantor under this Article XI shall be computed as if such monies had never been paid by or on behalf of Seller.

Section 11.5 Primary Liability of Guarantor. The Guarantor agrees that Buyer may enforce the guaranty in this Article XI without the necessity at any time of resorting to or exhausting any other security or collateral of any Person. The guaranty set forth in this Article XI is a continuing guaranty of payment and performance and not merely of collection.

IN WITNESS WHEREOF, this Agreement has been duly executed and delivered by the duly authorized officer of each Party as of the date first above written.
