Governmental Authority) and, to the Knowledge of Seller, no circumstances exist which could serve as a basis for the institution of such proceedings.

(f)      Each Seller Benefit Plan that is intended to be qualified under Section 401(a) of the Code has received from the IRS a favorable determination letter (or in the case of a master or prototype plan, a favorable opinion letter or in the case of a volume submitter plan, a favorable advisory letter) as to its qualification under Section 401(a) of the Code, and nothing has occurred that would be reasonably expected to adversely affect the qualified or exempt status of such Seller Benefit Plan or trust, nor is the consummation of the transactions provided for by this Agreement reasonably expected to have any such effect.

(g)      Each Seller Benefit Plan is being, and has been, operated and administered in accordance with ERISA, the Code and all other applicable Laws and regulations thereunder, in accordance with its terms, and so as not to incur any Liability for Taxes or penalties under ERISA, the Code or other Applicable Laws or Liability to any participant in such Seller Benefit Plan (other than routine claims for benefits).

(h)      Neither the execution of this Agreement nor the consummation of the transactions contemplated by this Agreement (whether alone or in connection with other events) will (i) entitle any Business Employee to compensation or benefits or any increase in compensation or benefits, (ii) accelerate the time of any payment or vesting or result in any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable under or result in any other obligation pursuant to, any Seller Benefit Plan, or (iii) constitute an event described in Section 280G(b)(2)(A)(i) of the Code, in any such case, for which Seller or the Company will be responsible.

(i)      Other than routine claims for benefits, there are no pending or, to the Knowledge of Seller, threatened Actions or Proceedings relating to a Seller Benefit Plan. There are no pending or open examinations of any Seller Benefit Plan by any Governmental Authority that could result in material liability to the Company.

(j)      No Business Employee has a vested right under any Seller Benefit Plan that is a retiree welfare benefit plan, and following the Closing the Company will have no Liability under any such retiree welfare benefit plan.

(k)      Notwithstanding anything to the contrary herein, except as set forth in Section 4.13 and this Section 4.14 , no representations or warranties are being made in this Agreement with respect to any employee or employee benefit matters, including such matters arising under ERISA or the Code.

If, in the absence of a protective order, a party or any of its representatives reasonably believes in good faith, after consulting with counsel, that it is required by Applicable Law to disclose Confidential Information of the other party, or that such disclosure is required in order to obtain any Required Regulatory Approval, the disclosing party shall (or shall cause its representatives to) furnish only that portion of the Confidential Information of the other party that the disclosing party or its representatives reasonably believe is so required.

(d)      It is expressly understood by the parties that Buyer is subject to Chapter 552 of the Texas Government Code (the “ Public Information Act ”).  Release of Confidential Information by either party for the limited purposes authorized herein is not to be construed as a waiver of any exceptions to the Public Information Act’s disclosure requirements that may apply to the Protected Information. 

Section 6.05      Post-Closing Access; PPA Payment .

(a)      On and after the Closing Date, Buyer will cause the Company to afford promptly to Seller and its agents reasonable access to its properties, books of account, financial and other records (including accountant’s work papers), information, employees and auditors to the extent necessary or useful for Seller in connection with any audit, investigation, dispute or litigation or any other reasonable business purpose relating to the Company; provided that any such access by Seller will not unreasonably interfere with the conduct of the business of the Company. Seller will bear all of the out-of-pocket costs and expenses (including attorneys’ fees, but excluding reimbursement for general overhead, salaries and employee benefits) reasonably incurred in connection with the foregoing.

(b)      Promptly after the Closing Date, and in no event later than fifteen calendar days after the Closing Date, Buyer shall pay or cause to be paid to Seller any accounts receivable due from Buyer or other amounts to be paid by Buyer that were accrued on or prior to the Closing Date pursuant to the PPA (collectively, the “ PPA Payments ”), subject to a true-up adjustment if additional information becomes known, in which case an invoice for such adjustment shall be paid not later than fifteen days after Buyer’s receipt of such invoice.

Section 6.06      Contact with Customers and Suppliers . Prior to the Closing, Buyer and Buyer’s representatives will contact and communicate with the employees, customers, resellers, vendors, suppliers and other business relations (other than potential financing sources) of the Company, or of Seller or its other Affiliates with respect to the Company’s operations, in connection with the transactions contemplated by this Agreement only to the extent permitted by Applicable Law and only with the prior written consent of Seller, not to be unreasonably withheld, conditioned, or delayed.

Section 6.07      Employee Matters .

(a)      Employee Information Updates. Between the date of this Agreement and the Closing, Seller shall notify Buyer as soon as reasonably practicable of any changes to the Employee List as a result of (a) the hiring of a Business Employee by Seller or its applicable Affiliates, (b) the termination of a Business Employee’s employment with Seller or its Affiliates or (c) the transfer of a Business Employee to another position with Seller and its Affiliates. Prior to Closing, Seller shall provide Buyer reasonable access to Seller’s premises and records relating to the Business Employees to the extent permitted by Applicable Law. The Parties agree that Seller and its Affiliates may continue to post job openings on internal job boards, and otherwise communicate about and advertise such job openings with Business Employees in the ordinary course of business, consistent with past practice. Furthermore, the Parties agree that Seller and its Affiliates may transfer the employment of the Business Employees (such that such individuals remain employed by Seller or its Affiliates but are no longer Business Employees) in the ordinary

course of business, consistent with past practice, subject to the terms and conditions of the Transition Services Agreement.

(b)      Offers of Employment to Business Employees . Buyer shall, or shall cause a third-party operations and maintenance provider (the “ O&M Provider ”) to, give offers of employment at the Facility to each of the Business Employees no later than ten Business Days prior to the Closing Date. Such offers of employment will comply with the requirements of Section 6.07(c) and shall be contingent upon and effective as of the occurrence of the Closing. Should Buyer or the O&M Provider, as applicable, also wish to make offers contingent upon any other conditions, including post-offer background, drug and/or alcohol screenings, Buyer shall ensure that such screenings shall not be conducted any sooner than 30 days prior to the Closing Date. Notwithstanding the foregoing, Buyer shall not be required, and shall not be required to cause the O&M Provider, to make an offer of employment to any employee of Seller who is on long-term disability leave as of the Closing Date (a “ Disability Employee ”) unless such Disability Employee who otherwise would have been a Business Employee returns to active employment during the Continuation Period (as defined below). A Business Employee who is on short-term disability leave as of the Closing Date who subsequently qualifies for long-term disability benefits shall receive long-term disability benefits pursuant to the applicable Seller Benefit Plan (under which Seller and its Affiliates shall retain all Liabilities) and not pursuant to a long-term disability benefit plan of Buyer.

A Business Employee who accepts an offer of employment and becomes employed by Buyer or the O&M Provider or their Affiliates is referred to as a “ Transferring Employee .” It is expressly understood and agreed that Buyer’s or the O&M Provider’s, as applicable, offers to Business Employees shall not constitute any commitment, contract or understanding, express or implied, of any obligation on the part of Buyer, the O&M Provider or their Affiliates to a post-Closing employment relationship of any fixed term. Any such Business Employee who transfers employment within, or accepts a position with, Seller or its Affiliates prior to the Closing Date shall no longer be considered a Business Employee and shall not become a Transferring Employee. Severance or other separation benefits will not be offered by Seller to any Business Employee who (i) rejects Buyer’s or O&M Provider’s offer of employment in a job position that is similarly situated to the job position the Business Employee held immediately prior to the Closing at the Facility, (ii) has an offer of employment rescinded by the O&M Provider due to non-compliance with any pre-employment screening, or (iii) otherwise voluntarily leaves employment with Seller prior to the Closing Date.

(c)      Compensation and Employee Benefits .

(i)      Compensation and Benefits Comparability . For a period commencing on the Closing Date and expiring at the end of the first full calendar year following the year in which the Closing Date occurs (the “ Continuation Period ”), Buyer will, or will cause the O&M Provider to, provide to each Transferring Employee, for so long as such Transferring Employee remains employed during the Continuation Period, (A) base pay and annual incentive compensation opportunities that are not less than such Transferring Employee’s base pay and annual incentive compensation opportunities immediately prior to the Closing and (B) a total value of employee benefits that are, in the aggregate, at least as favorable as the employee benefits provided to the Transferring Employees by Seller

(including equity-based compensation, severance benefits, retiree health benefits, retiree life benefits, pension, medical costs, 401(k) matching, life insurance, long term disability and other employee benefits specifically required pursuant to this Section 6.07 , but specifically excluding voluntary benefits), it being understood that the provisions of this sentence shall cease to apply with respect to a Transferring Employee upon termination of such Transferring Employee’s employment with Buyer, the O&M Provider and their Affiliates, as applicable, and that Buyer or the O&M Provider, as applicable, need not replicate specific items of employee benefits and may satisfy its obligations through a different combination of employee benefits than are provided prior to the Closing Date. Provided that Buyer makes contributions to each Transferring Employee’s account under Buyer’s 401(k) Plan (as defined below) and/or provides cash bonuses to such Transferring Employee that, in the aggregate, equal or exceed the value indicated on the Employee List for each such Transferring Employee related to lost pension, retiree health, retiree life and equity-based compensation benefits during the Continuation Period, Seller agrees that Buyer shall have met Buyer’s obligations specifically for the value of lost pension, retiree health, retiree life and equity-based compensation benefits under clause (B) of this Section 6.07(c)(i) . For the avoidance of doubt, nothing in this Agreement shall be construed to require Buyer or the O&M Provider to offer (i) retiree health or retiree life benefits, (ii) defined benefit pension benefits, (iii) voluntary benefits, or (iv) equity-based compensation to any Transferred Employees. If any Transferring Employee’s employment is terminated without cause during the Continuation Period, subject to such Transferring Employee’s execution and non-revocation of a release of claims against Seller and, as applicable, Buyer or the O&M Provider, Buyer will, or will cause the O&M Provider to, provide such Transferring Employee with the severance benefits pursuant to the terms of Seller’s applicable severance plan or policy as set forth on Schedule 6.07(b) ; provided, however, that the calculation of any such severance benefits shall take into account such Transferring Employee’s service with Seller or its Affiliate. Following the Closing Date, Seller shall have no liability with respect to severance benefits for Transferring Employees whose employment is terminated by Buyer or the O&M Provider, and Buyer shall, or shall be obligated to cause the O&M Provider to, pay the benefit for and indemnify and hold harmless Seller and its Affiliates from any claim by or on behalf of any Transferring Employee for any severance benefits alleged to be payable by Buyer or the O&M Provider. The form and terms of any particular benefit plan offered by Buyer or the O&M Provider, as applicable, shall be as determined by Buyer or the O&M Provider, as applicable, subject to the foregoing and the other provisions of this Article 6 .

(ii)      Service Credit . Buyer will, or will cause the O&M Provider to, recognize the service (including industry experience, as applicable) of each of the Transferring Employees recognized by Seller for all benefits purposes, including eligibility for, vesting and accrual of, and determination of the levels of such benefits. However, service will not be recognized to the extent it would result in duplication of benefits for the same period of service or for purposes of grandfathered benefits.

(iii)      Welfare Plans . Buyer will, or will cause the O&M Provider to, use reasonable best efforts to waive or cause the waiver of any limitation on benefits relating to pre-existing conditions, actively-at-work exclusions, evidence of insurability and

waiting periods for the Transferring Employees under any plan sponsored or maintained by Buyer, the O&M Provider or their Subsidiaries, as applicable, in which the Transferring Employees participate immediately after the Closing Date providing medical, life or disability benefits, to the extent that such limitations are waived or otherwise inapplicable to a Transferring Employee under any comparable plan of Seller as of the Closing Date. Buyer shall, or shall cause the O&M Provider to, use reasonable best efforts to cause all healthcare expenses incurred by Transferring Employees or any eligible dependent thereof, including any alternate recipient pursuant to qualified medical child support orders, in the portion of the calendar year preceding the Closing Date that were qualified to be taken into account for purposes of satisfying any deductible or out-of-pocket limit under any Seller health care plan will be taken into account for purposes of satisfying any deductible or out-of-pocket limit under the healthcare plan of Buyer or the O&M Provider for such calendar year. Seller will use reasonable best efforts to provide such information to Buyer or Buyer’s designee. Seller will be responsible for making available COBRA Continuation Coverage to any current and former employees of Seller, including Business Employees, or to any qualified beneficiaries of such employees, who become entitled to COBRA Continuation Coverage as a result of loss of group health coverage under a Seller Benefit Plan. Buyer will, or will cause the O&M Provider to, be responsible for making available COBRA Continuation Coverage to any Transferring Employees (and their qualified beneficiaries) who become entitled to such COBRA Continuation Coverage on or after the Closing Date as a result of their loss of group health plan coverage under any plan sponsored or maintained by Buyer or the O&M Provider, as applicable.

(iv)      Vacation . Seller agrees to be solely responsible and liable for all banked vacation or banked personal time off as of December 31, 2018 for all Transferring Employees, and hereby agrees to provide a cash payment to all such Transferring Employees in an amount equal to the cash equivalent of all such banked vacation or banked personal time off based upon the Transferring Employee’s wage or salary on the day prior to the Closing Date. From and after the Closing Date, Buyer shall, or shall cause the O&M Provider to, assume and honor all vacation service dates of the Transferring Employees and credit each Transferring Employee with all vacation and other personal time off of the Transferring Employee accrued on or after January 1, 2019, but unused prior to the Closing Date; provided, however, if Seller or any of its Affiliates is required under Applicable Law to make a payment in settlement of vacation and other personal time-off of any Transferring Employee that was accrued on or after January 1, 2019, but unused, Buyer shall make such payment or reimburse and hold harmless Seller and its Affiliates for such payment. Nothing in this Agreement shall be construed to require Buyer or the O&M Provider to continue any ability of the Transferred Employees to carry over unused vacation or paid time off after the end of the Continuation Period.

(v)      Disability Benefits; Worker’s Compensation; Paid Leave . Through the Closing Date, Seller or its Affiliates shall maintain the short-term disability and long-term disability plans or programs, worker’s compensation, and any related insurance policies or other funding or administrative arrangements, presently in effect with respect to the Business Employees, and will handle any claim for benefits thereunder in the ordinary course of business. Prior to the Closing Date, Seller or its Affiliates shall make reasonable

best efforts to transfer and assign all such insurance policies and other funding arrangements, to the extent applicable to the Transferring Employees, and Seller’s or its Affiliate’s rights thereunder to Buyer, the O&M Provider or their Affiliates, as applicable, effective as of the Closing Date, at which time Buyer, the O&M Provider or their Affiliates, as applicable, shall assume responsibility for all such disability benefits (other than worker’s compensation benefits) in respect of the Transferring Employees. Seller shall retain liability for (A) all worker’s compensation benefits with respect to claims incurred prior to the Closing Date and (B) long-term disability claims for Transferred Employees receiving short-term disability benefits as of the Closing Date. If Seller, its Affiliate, or the insurance carrier of Seller or its Affiliate makes any payments for short-term disability, long-term disability, or worker’s compensation to or on behalf of a Transferring Employee that are the responsibility of Buyer or the O&M Provider as provided in this Agreement, Buyer shall reimburse Seller or its Affiliate, as applicable, for the payments, promptly after receipt of any accounting statement from Seller, to the extent of Seller’s or its Affiliate’s out-of-pocket costs therefor, and if Buyer, the O&M Provider or the insurance carrier of Buyer or the O&M Provider makes any such payments that are the responsibility of Seller or its Affiliate as provided in this Agreement, Seller shall reimburse Buyer or the O&M Provider for the payments, promptly after receipt of any accounting statement from Buyer or the O&M Provider, as applicable, to the extent of such Person’s out-of-pocket costs therefor. In addition, for the Continuation Period, Buyer shall, or shall cause the O&M Provider to, continue to provide (x) compensation and employee benefits to all Transferring Employees pursuant to the paid leave policies of Seller in effect immediately prior to the Closing and (y) employee benefits to all Transferring Employees on disability leave pursuant to the disability leave of absence policies of Seller in effect immediately prior to Closing, provided that, nothing in this subsection (v) shall require Buyer or the O&M Provider to offer any benefit excluded by subsection (i) of this Section 6.07(c) during or after any paid time off or disability leave of absence.

(d)      Benefit Plan Assets and Liabilities Generally .

(i)      Seller Benefit Plans . From and after the Closing Date, the Transferring Employees shall cease to be active participants in the Seller Benefit Plans that are not Company Benefit Plans.

(ii)      Flexible Spending Accounts . As of the Closing Date, with respect to each Transferring Employee participating immediately prior to the Closing Date in any Seller Benefit Plan or Company Benefit Plan that is a health flexible spending account or dependent care flexible spending account plan (the “ Seller FSA Plans ”), Seller will, or will cause the Company to, transfer from the Seller FSA Plans to the applicable health flexible spending account or dependent care flexible spending account plan designated by Buyer or the O&M Provider, as applicable, (the “ Buyer FSA Plan ”), the account balances (positive or negative) of such Transferring Employees. Each Transferring Employee will be permitted to continue to have payroll deductions made pursuant to the Buyer FSA Plan as most recently elected by him or her under the applicable Seller FSA Plan. As soon as reasonably practicable following the Closing Date, Seller will provide Buyer or its designee with a reconciliation of the underspent and overspent flexible spending accounts of

Transferring Employees in the Seller FSA Plans. Amounts forfeited by Transferring Employees in the Buyer FSA Plan at the end of the plan year during which the Closing occurs will be assets of Buyer or the O&M Provider, as applicable.

(iii)      Incentive Program . Within 30 days following the Closing Date, Seller shall pay or cause to be paid to each Transferring Employee who is a participant in an annual cash performance pay program of Seller (a “ PPP ”) the amount of compensation accrued, but not paid, through the Closing Date, with respect to such Transferring Employee under the PPP.

(e)      Retirement Plans .

(i)      Seller shall fully vest all Transferring Employees in their account balances under the Southern Company Employee Savings Plan (the “ Seller’s 401(k) Plan ”), effective as of the Closing Date. Effective as of the Closing Date, Buyer shall, or shall cause the O&M Provider to, maintain or designate, or cause to be maintained or designated, a defined contribution plan and related trust intended to be qualified under Sections 401(a), 401(k) and 501(a) or 403(b) of the Code (the “ Buyer’s 401(k) Plan ”). Effective as of the Closing Date, the Transferring Employees shall cease participation in Seller’s 401(k) Plan, and the Transferring Employees shall be eligible to participate and shall commence participation in Buyer’s 401(k) Plan in accordance with the terms of Buyer’s 401(k) Plan. Seller and Buyer shall cooperate, and Buyer shall, or shall cause the O&M Provider to, cooperate, to permit each Transferring Employee to make rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) to Buyer’s 401(k) Plan in cash in an amount equal to the full account balance distributed to such Transferring Employee from Seller’s 401(k) Plan. Buyer will, or will cause the O&M Provider to, use reasonable best efforts to permit such rollover contributions in the form of notes representing an employee loan under Seller’s 401(k) Plan and Buyer shall, or shall cause the O&M Provider to, take (or cause to be taken) any and all reasonable action as may be required to provide that Transferring Employees may continue to service any such loans through payroll deductions after the Closing Date.

(ii)      With regard to the Seller Pension Plan, each Transferring Employee shall cease to be a participant under such plan effective as of the Closing. Seller shall fully vest all Transferring Employees participating in the Seller Pension Plan in their accrued benefit under such plan effective as of the Closing.

action or omission of Buyer or its Affiliates or the O&M Provider occurring following the Closing Date.

(g)      No Third-Party Beneficiaries . The provisions of this Section 6.07 are solely for the benefit of the parties to this Agreement, and no current or former employee, director or independent contractor or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of the Agreement, and nothing herein shall be construed as an amendment to any employee benefit plan (sponsored by Seller or Buyer) for any purpose. Nothing in this Section 6.07 shall be construed to (i) limit the right of Seller, Buyer or any of their respective Affiliates to amend or terminate any employee plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, or (ii) require Buyer or any of its Affiliates to retain or cause the retention of the employment of any particular Transferring Employee for any fixed period of time following the Closing Date.

Prior to the expiration of such time period, Buyer agrees to give (or cause to be given to) Seller reasonable notice prior to transferring, discarding or destroying any such books and records relating to Tax matters and, if Seller so requests, Buyer will allow Seller to take possession of such books and records.

Buyer will cause the Company, to the extent permitted by Applicable Law, to carry forward any Tax asset arising in any Post-Closing Period that could be carried back to a Pre-Closing Period.

If any dispute regarding the Allocation Schedule remains unresolved after 60 days following Buyer’s delivery of such Allocation Schedule to Seller, then each of Buyer and Seller shall make its own determination as to the allocation contemplated by this Section 6.12(f) . If Buyer and Seller reach agreement on a final Allocation Schedule, Buyer and Seller shall file all Tax Returns (including IRS Form 8594) in a manner consistent with the final Allocation Schedule and neither Buyer nor Seller shall take any position (whether in Tax Claims, on Tax Returns, or otherwise) that is inconsistent with such Allocation Schedule except as may be adjusted by subsequent agreement following an audit by the Internal Revenue Service or by court decision.

Buyer agrees that it will, and that it will cause the Company to, make any claims on such policies only through Seller. Seller shall submit such claims and use its commercially reasonable efforts to (x) administer such claims, at Buyer’s or the Company’s sole cost and expense, on behalf of Buyer and the Company (it being understood and agreed that Seller shall have the right to administer and control such claims, in consultation with Buyer) and (y) seek reasonable recovery for such claims under the applicable insurance provisions of such policies. Buyer or the Company shall be responsible for all deductibles, retentions, self-insurance or payments of reimbursement obligations relating to such claims.

and expense.

As also previously disclosed to Buyer, Seller is obtaining an updated or separate title commitment to cover the land covered by the Underground Pipeline Easement Agreement, dated March 2, 2011, from Angelina and Nacogdoches Counties Water Control & Improvement District No. 1, as Grantor, to the Nacogdoches Power, LLC, recorded in Volume 3070, Page 93, Rusk County, Texas, which Seller agrees to deliver to Buyer as soon as reasonably practicable after the date hereof, and in any event by May 8, 2019 (the “ New Commitment ”). Notwithstanding the foregoing, such requested cooperation shall not unreasonably interfere with the ongoing operation of the Company, and the Company shall not be required to make any payment or incur any cost, expense, liability, or obligation in connection with Buyer’s efforts to obtain Updated Title Evidence or new or updated ALTA survey; provided, that if Buyer elects to obtain Updated Title Evidence, Seller and the Company shall deliver to the title company a standard owner’s affidavit (with such commercially reasonable modifications as Seller may require), copies of organizational documents and authorizing resolutions, and other documents reasonably required by the title company to issue such Updated Title Evidence. Buyer shall, promptly upon request of Seller, reimburse Seller and the Company (prior to Closing) for all out-of-pocket costs and expenses reasonably incurred by Seller or the Company in connection with the cooperation required by this Section 6.24 . If any of the Updated Title Evidence, the New Survey, the Updated Survey, or the New Commitment shows any title exceptions, documents or other matters that are not Permitted Liens and that could reasonably be expected to materially and adversely affect the ability to operate the Facility consistent with past practice, then Buyer shall have the right to approve or disapprove any such matters by written notice to Seller prior to May 14, 2019, and Seller shall use commercially reasonable efforts to cure such all such timely objections at its sole cost and expense.

Party ”), the Indemnitee will promptly give written notice (a “ Third Party Claim Notice ”) of such Third Party Claim to the Indemnifying Party.

(c)      Defense of Third Party Claims .

Subject to Section 8.04(b) , the Indemnifying Party will, in consultation with the Indemnitee, make all decisions and determine all actions to be taken with respect to the defense and settlement of the Third Party Claim; provided , however, that the Indemnifying Party shall not pay, compromise, settle, or otherwise dispose of such Third Party Claim without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld, conditioned or delayed, provided that it will not be deemed to be unreasonable for an Indemnitee to withhold its consent if (i) such payment, compromise, settlement or disposition does not involve solely the payment of money, (ii) such payment, compromise, settlement or disposition involves a finding or admission of violation of any Applicable Law, Order or permit or rights of any Person by the Indemnitee or its Affiliates or (iii) such payment, compromise, settlement or

disposition does not contain an unconditional release of the Indemnitee from the subject matter of such payment, compromise, settlement or disposition. In no event will the Indemnifying Party have authority to agree, without the consent of the Indemnitee, to any relief binding on the Indemnitee other than the payment of money damages by the Indemnifying Party without recourse to the Indemnitee.

(d)      Failure to Assume Defense . If the Indemnifying Party elects not to defend such Third Party Claim, fails to timely notify the Indemnitee in writing of its election to defend, or fails to diligently prosecute the defense of such Third Party Claim, the Indemnitee may defend such Third Party Claim and seek indemnification for any and all indemnifiable Losses based upon, arising from or relating to such Third Party Claim; provided , however, that the Indemnitee shall not pay, compromise, settle, or otherwise dispose of such Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed).

(e)      Direct Losses . Any claim by an Indemnitee on account of an indemnifiable Loss that does not result from a Third Party Claim (a “ Direct Loss ”) will be asserted by giving the Indemnifying Party prompt written notice thereof, (i) describing the nature, facts and circumstances of such indemnifiable Loss in reasonable detail, (ii) stating the amount of the indemnifiable Loss that has been or may be sustained by the Indemnitee, if practicable, (iii) stating the method and computation thereof and (iv) containing specific reference to the provision or provisions of this Agreement in respect of which such right of indemnification is claimed or arises. The Indemnitee shall provide the Indemnifying Party with such other information with respect to the Direct Loss as the Indemnifying Party may reasonably request and shall cooperate with the Indemnifying Party and its counsel, including permitting reasonable access to books, records, and personnel, in connection with determining the validity of any claim for indemnification by the Indemnitee and in otherwise resolving such matters. The Indemnifying Party will have a period of 20 days within which to respond to such claim of a Direct Loss. If the Indemnifying Party rejects such claim, or does not respond within such period, the Indemnitee may seek enforcement of its rights to indemnification under this Agreement.

(f)      Delay . A failure to give timely notice as provided in this Section 8.04 will affect the rights or obligations of a party or Indemnitee hereunder only to the extent that, as a result of such failure, the party entitled to receive such notice was actually prejudiced as a result of such failure. Notwithstanding the foregoing, no claim for indemnification first made after the expiration of the applicable survival period with respect to the representation, warranty or covenant on which such claim is based set forth in Section 8.01 will be valid and any such claim shall be deemed time-barred.

(g)      Payments . Once a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this Article 8 , the Indemnifying Party shall satisfy its indemnity obligations hereunder within ten Business Days after such agreement or final adjudication, by wire transfer of immediately available funds in accordance with instructions provided by the Indemnitee.

(h)      Materiality Scrape . Notwithstanding anything to the contrary in this Agreement, (i) for purposes of calculating Losses in connection with a claim for indemnification under this

Article 8 (but not for purposes of determining whether there has been a breach of any such representation, warranty, covenant or agreement which is addressed in clause (ii) ), each of the representations, warranties, covenants and agreements that contain any qualifications as to materiality or Material Adverse Effect shall be deemed to have been given as though there were no such qualifications, and any such qualification shall be disregarded for purposes of calculating the amount of any such Losses and (ii) for purposes of determining whether there has been a breach in connection with a claim for indemnification under this Article 8 (but not for purposes of determining Losses which are addressed in clause (i) ), each of the representations, warranties, covenants and agreements that contain a Material Adverse Effect qualification shall be deemed to have been given as though such representation, warranty, covenant or agreement was instead qualified by materiality.

Section 8.05      Exclusive Remedy . Except (i) with respect to the matters covered by Section 2.03 , Section 2.04 , Section 2.05 and Section 2.06 (which shall be exclusively governed by such Sections) (ii) with respect to any matter relating to Taxes (which shall be governed exclusively by Section 6.12 ), (iii) insurance matters covered by Section 6.23 and (iv) for the parties’ right to seek and obtain any equitable relief pursuant to Section 10.14 , the parties acknowledge and agree that, following the Closing, the indemnification provisions of Sections 8.02 and 8.03 shall be the sole and exclusive remedies of the parties for any Liabilities or Losses (including any Liabilities or Losses from claims for breach of contract, warranty, tortious conduct (including negligence) or otherwise and whether predicated on common law, statute, strict liability, or otherwise) that each party may at any time suffer or incur, or become subject to, as a result of, or in connection with the transactions contemplated hereby, including any breach of any representation or warranty in this Agreement by any party, or any failure by any party to perform or comply with any covenant or agreement that, by its terms, was to have been performed, or complied with, under this Agreement. In furtherance of the foregoing, Seller and Buyer hereby waive, on behalf of themselves and the other Seller Indemnified Parties and Buyer Indemnified Parties, respectively, to the fullest extent permitted by Applicable Law, any and all other rights, claims and causes of action (including rights of contribution, rights of recovery arising out of or relating to any Environmental Laws, claims for breach of contract, breach of representation or warranty, negligent misrepresentation and all other claims for breach of duty) that may be based upon, arise out of, or relate to this Agreement, the negotiation, execution or performance of this Agreement (including any tort or breach of contract claim or cause of action based upon, arising out of, or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), or the transactions contemplated hereby, known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against the other arising under or based upon any Applicable Law, common law, or otherwise.

Section 8.06      Additional Indemnification Provisions . With respect to each indemnification obligation contained in this Article 8, all Losses shall be net of indemnity proceeds that have been recovered by the Indemnitee in connection with the facts giving rise to the right of indemnification (it being agreed that if indemnification proceeds in respect of such facts are recovered by the Indemnitee subsequent to the Indemnifying Party’s making of an indemnification payment in satisfaction of its applicable indemnification obligation, such proceeds shall be promptly remitted to the Indemnifying Party to the extent that the indemnification payment made exceed the Losses incurred), and the Indemnitee shall use, and cause its Affiliates to use,

commercially reasonable efforts to seek recovery under all indemnity provisions covering such Losses to the same extent as it would if such Losses were not subject to indemnification hereunder.

Section 8.07      Limitation on Consequential Damages . Notwithstanding anything to the contrary elsewhere in this Agreement or provided for under any Applicable Law, no party will be liable to the other party, either in contract or in tort, for any consequential, incidental, indirect, special, or punitive damages of the other party, including business interruption, loss of future revenue, profits or income, diminution in value or loss of business reputation or opportunity, relating to the breach or alleged breach hereof or otherwise, whether or not the possibility of such damages has been disclosed to the other party in advance or could have been reasonably foreseen by such other party, and, in particular, no “multiple of profits,” “multiple of cash flow,” “multiple of assets” or similar valuation methodology shall be used in calculating the amount of any indemnifiable Losses. The exclusion of consequential, incidental, indirect, special, and punitive damages as set forth in the preceding sentence does not apply to any such damages under any Third Party Claim, in connection with Losses that may be indemnified pursuant to this Article 8 after Closing.

Section 8.08      Mitigation .

(a)      Each of the parties agrees to use its commercially reasonable efforts to mitigate its respective Losses upon and after becoming aware of any event or condition that would reasonably be expected to give rise to any Losses that are indemnifiable hereunder, and no Indemnifying Party shall be liable for any Losses to the extent they arise out of or result from the Indemnitee’s failure to use commercially reasonable efforts to mitigate such Losses.

(b)      The amount of any indemnifiable Loss will be reduced to the extent of any insurance proceeds or other payments actually received from an insurer or other third party with respect to an indemnifiable Loss, or any Tax benefit actually realized in cash or a reduction in Taxes otherwise payable as a result of such Loss prior to the date such indemnity payment is made, in each case, net of all costs of recovery. If the amount of any indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement, or payment under or pursuant to any insurance coverage or by recovery, settlement, or payment by or against any other Person, the amount of such reduction (net of all costs of recovery), will be repaid by the Indemnitee to the Indemnifying Party reasonably promptly following actual receipt or credit of such amounts.

(c)      Upon making any indemnity payment, the Indemnifying Party will, to the extent of such indemnity payment, be subrogated to all rights of the Indemnitee against any third party in respect of the indemnifiable Loss to which the indemnity payment relates.
