CHK and SSE shall take any and all reasonable action as shall be necessary and appropriate to further the provisions of this Article III.

(b) Where an award granted under one of the CHK Legacy Equity Plans is replaced by an award under the SSE Equity Plan in accordance with the provisions of this Article III, such award generally shall be on terms which are in all material respects identical to the terms of the award which it replaces (including any requirements of continued employment) but subject to any necessary changes to take into account that (i) the award relates to SSE Common Stock, (ii) the SSE Equity Plan is administered by SSE, and (iii) if applicable, the grantee under the award is employed or affiliated with a new employer or plan sponsor.

(c) Following the Distribution, a grantee who has outstanding awards that are replaced with awards under the SSE Equity Plan (as described in Section 3.1(b) above) shall be considered to have been employed by the applicable plan sponsor before and after the Distribution for purposes of (1) vesting and (2) determining the date of termination of employment as it applies to any such replacement awards under the SSE Equity Plan.

Any period of exercisability will not be extended on account of a period during which such an award is not exercisable in accordance with the preceding sentence.

Stock dividend (calculated using the SSE Share Price). In each case the number of restricted shares of SSE common stock under the Replacement SSE RSA shall be equal to the result of ((X) multiplied by (Y)) divided by (Z), where “X” is equal to the Pre-Distribution CHK Share Price, “Y” is equal to (A) plus (B), where “A” is equal to the result of (i) the number of restricted shares of CHK Common Stock subject to the CHK RSA being cancelled and replaced pursuant to this Section 3.2(a), multiplied by (ii) the Distribution Ratio multiplied by (iii) the SSE Share Price, the product of (i)-(iii) is then divided by the Post-Distribution CHK Share Price and “B” is the number of restricted shares of CHK Common Stock subject to the CHK RSA being cancelled and replaced pursuant to this Section 3.2(a) and “Z” is the SSE Share Price, with the resulting number being rounded down to the nearest whole share.

CHK (or one or more of the CHK Subsidiaries, as designated by CHK) shall be responsible for (i) the satisfaction of all tax reporting and withholding requirements in respect of the Adjusted CHK RSAs and (ii) responsible for remitting the appropriate tax or withholding amounts to the appropriate taxing authorities in respect of the distribution and vesting of all such restricted shares.

Stock dividend (calculated using the SSE Share Price). In each case the number of restricted stock units with respect to and payable in shares of SSE Common Stock or (if, but only if, provided for under the terms of the applicable CHK RSU) cash under the Replacement SSE RSU shall be equal to the result of ((X) multiplied by (Y)) divided by (Z), where “X” is equal to the Pre-Distribution CHK Share Price, “Y” is equal to (A) plus (B), where “A” is equal to the result of (i) the number of restricted shares of CHK Common Stock subject to the CHK RSU being cancelled and replaced pursuant to this Section 3.3(a), multiplied by (ii) the Distribution Ratio multiplied by (iii) the SSE Share Price, the product of (i)-(iii) is then divided by the Post-Distribution CHK Share Price and “B” is the number of restricted shares of CHK Common Stock subject to the CHK RSU being cancelled and replaced pursuant to this Section 3.3(a) and “Z” is the SSE Share Price, with the resulting number being rounded down to the nearest whole unit.

In each case the number of Adjusted CHK RSUs shall be equal to the result of (X) divided by (Y), where “X” is (i) the number of units subject to the CHK RSUs multiplied by (ii) the Distribution Ratio multiplied by (iii) the SSE Share Price and “Y” is equal to the Post-Distribution CHK Share Price, with the resulting number being rounded down to the nearest whole unit. CHK (or one or more of the CHK Subsidiaries, as designated by CHK) shall be responsible for (i) the satisfaction of all tax reporting and withholding requirements in respect of the vesting of the Adjusted CHK RSUs or distribution of CHK Common Stock to CHK Employees and (ii) remitting the appropriate tax or withholding amounts to the appropriate taxing authorities in respect of the distribution and vesting of all such restricted stock units.

(a) Each grantee under any of the CHK Legacy Equity Plans (i) who will be a SSE Employee and (ii) who holds as of the Distribution Date, one or more CHK Options, shall receive, effective as of the last to occur of the Distribution Date and the Registration Statement Effectiveness Date, as a replacement award in substitution for each such CHK Option (which shall be cancelled), an option to purchase a number of shares of SSE Common Stock under the SSE Equity Plan (each a “Replacement SSE Option”) having a value (calculated using the SSE

Share Price) equal to the value of the CHK Common Stock subject to the CHK Option (calculated using the Pre-Distribution CHK Share Price). The number of shares of SSE Common Stock subject to a Replacement SSE Option shall be equal to the product of (i) the number of shares of CHK Common Stock subject to a CHK Option as of the Distribution Date multiplied by (ii) a fraction, the numerator of which is the Pre-Distribution CHK Share Price and the denominator of which is the SSE Share Price, with the resulting number being rounded down to the nearest whole share. Each such Replacement SSE Option shall have the same comparative ratio of the exercise price to the SSE Share Price as the exercise price of each CHK Option to the Pre-Distribution CHK Share Price as provided under Code Section 424 and the applicable regulations thereunder. SSE shall be responsible for (i) the satisfaction of all tax reporting and withholding requirements in respect of the exercise of Replacement SSE Options issued in accordance with this Section 3.4(a) and (ii) remitting the appropriate tax or withholding amounts to the appropriate taxing authorities. Replacement SSE Options shall not be exercisable until the Registration Statement Effectiveness Date. Except as provided in the foregoing provisions of this Section 3.4(a), Replacement SSE Options granted under this Section 3.4(a) shall be granted on terms which are in all material respects identical (including with respect to vesting) to the terms of the CHK Options with respect to which they replace.

(b) Each grantee under any of the CHK Legacy Equity Plans (i) who is a CHK Legacy Award Holder, will be a CHK Employee or CHK Director and (ii) who will hold one or more CHK Options as of the Distribution Date, shall receive, effective as of the last to occur of the Distribution Date and the Registration Statement Effectiveness Date, in substitution for each such CHK Option (which shall be cancelled), an option to purchase shares of CHK Common Stock under one of the CHK Legacy Equity Plans (each a “Post-Distribution CHK Option”) having a value (calculated using the Post-Distribution CHK Share Price) equal to the value of the shares of CHK Common Stock subject to the CHK Option (calculated using the SSE Share Price). The number of shares of CHK Common Stock subject to a Post-Distribution CHK Option shall be equal to the product of (i) the number of shares of CHK Common Stock subject to a CHK Option as of the Distribution Date multiplied by (ii) a fraction, the numerator of which is the Pre-Distribution CHK Share Price and the denominator of which is the Post-Distribution CHK Share Price, with the resulting number being rounded down to the nearest whole share. Each such Post-Distribution CHK Option shall have the same comparative ratio of the exercise price to the Post-Distribution CHK Share Price as the exercise price of each CHK Option to the Pre-Distribution CHK Share Price as provided under Code Section 424 and the applicable regulations thereunder. CHK (or one or more of the CHK Subsidiaries, as designated by CHK) shall be responsible for (i) the satisfaction of all tax reporting and withholding requirements in respect of the exercise of Post-Distribution CHK Options issued in accordance with this Section 3.4(b) and (ii) remitting the appropriate tax or withholding amounts to the appropriate taxing authorities. Except as provided in the foregoing provisions of this Section 3.4(b), Post-Distribution CHK Options shall be granted on terms which are in all material respects identical (including with respect to vesting) to the terms of the CHK Options with respect to which they are substituted.

Section 3.5 CHK Performance Share Units. Each unvested CHK Performance Share Unit (that will not become vested as of the Distribution Date) under any of the CHK Legacy Equity Plans as of the Distribution Date shall be adjusted, on the last to occur of the Distribution Date and the Registration Statement Effectiveness Date, under one of the CHK Legacy Equity

Plans (in lieu of receiving any SSE Common Stock under the CHK Performance Share Unit) (each an “Adjusted CHK Performance Share Unit”). In each case the target number of Adjusted CHK Performance Share Units is equal to the result of (X) divided by (Y), where “X” is (i) the number of target units subject to the Adjusted CHK Performance Share Units multiplied by (ii) the Distribution Ratio multiplied by (iii) the SSE Share Price and “Y” is equal to the Post-Distribution CHK Share Price, with the resulting number being rounded down to the nearest whole unit. CHK (or one or more of the CHK Subsidiaries, as designated by CHK) shall be responsible for (i) the satisfaction of all tax reporting and withholding requirements in respect of the vesting of the Adjusted CHK Performance Share Units or distribution of CHK Common Stock and (ii) remitting the appropriate tax or withholding amounts to the appropriate taxing authorities in respect of the distribution and vesting of all such restricted stock units. Except as provided in the foregoing provisions of this Section 3.5, Adjusted CHK Performance Share Units shall retain terms which are in all material respects identical (including with respect to vesting) to the terms of the original award of CHK Performance Share Units. Adjusted CHK Performance Share Units are in addition to and not in lieu of the original award of the CHK Performance Share Units.

Section 3.6 Section 16(b) of the Exchange Act; Code Sections 162(m) and 409A.

(a) By approving the adoption of this Agreement, the respective boards of directors of CHK and SSE intend to exempt from the short-swing profit recovery provisions of Section 16(b) of the Exchange Act, by reason of the application of Rule 16b–3 thereunder, all acquisitions and dispositions of equity incentive awards by directors and executive officers of each of CHK and SSE, and the respective boards of directors of CHK and SSE also intend to expressly approve, in respect of any equity-based award, the use of any method for the payment of an exercise price and the satisfaction of any applicable tax withholding (specifically including the actual or constructive tendering of shares in payment of an exercise price and the withholding of option shares from delivery in satisfaction of applicable tax withholding requirements) to the extent such method is permitted under the applicable equity incentive plan and award agreement.

(b) Notwithstanding anything in this Agreement to the contrary, CHK and SSE agree to negotiate in good faith regarding the need for any treatment different from that otherwise provided herein to ensure that (i) a federal income tax deduction for the payment of any annual incentive or long–term incentive award, or other compensation is not limited by reason of Code Section 162(m), and (ii) the treatment of such annual incentive or long–term incentive award, or other compensation does not cause the imposition of a tax under Code Section 409A.

Section 3.7 Certain Bonus Payments. SSE shall assume responsibility for the grant of 2014 bonuses and liability for payment of bonuses for all SSE Employees earned under the CHK annual bonus plan, including any transition bonuses for SSE Employees. The 2014 annual incentive plan bonus opportunity of Jerry L. Winchester under the CHK annual bonus plan shall be cancelled, and SSE or a member of the SSE Group shall be responsible for payment of the 2014 annual bonus to such individual under a plan or arrangement maintained by SSE or a member of the SSE Group.

WELFARE PLANS

Except as provided below, the members of the SSE Group who had previously adopted a CHK Welfare Plan and were participating employers therein on the Distribution Date (“Participating SSE Employers”) shall on or before 11:59 p.m. on that date, withdraw from such participation, and, effective on or after the Distribution Date, Seventy Seven Operating, LLC and/or the Participating SSE Employers (with Seventy Seven Operating, LLC included in the definition of Participating SSE Employers for purposes of this Article VI) shall assume sponsorship, under newly established welfare plans, of the coverage and benefits which were offered under such plans to the SSE Employees and the Former SSE Employees (and their eligible spouses and dependents as the case may be) of the Participating SSE Employers (collectively, the “SSE Welfare Plan Participants”). The appropriate SSE Entity shall ensure that such coverage and benefits are provided to the SSE Welfare Plan Participants on an uninterrupted basis. Except as provided below, effective as soon as possible after the Distribution Date, liabilities relating to the SSE Welfare Plan Participants shall be spun off from each CHK Welfare Plan and allocated to the corresponding new SSE Welfare Plan.

As a result of withdrawal from participation in the CHK Welfare Plans by the Participating SSE Employers, the SSE Welfare Plan Participants ceased to be eligible for coverage as an active employee under the CHK Welfare Plans at 11:59 p.m. on the Distribution Date. SSE Welfare Plan Participants shall not participate in any CHK Welfare Plans after the effective date of the SSE Welfare Plans.

Section 6.2 Transitional Matters Under SSE Welfare Plans.

(a) Treatment of Claims Incurred.

(i) Self-Insured Benefits. SSE has assumed and is responsible for the funding of payment for any unpaid covered claim and eligible expense incurred by any SSE Welfare Plan Participant prior to the Distribution Date under a CHK Welfare Plan that is not described in Section 6.2(a)(ii) below, to the extent such participant has coverage under such plan as, or through, an employee or former employee of a Participating SSE Employer on the date such claim or expense is incurred. No member of the CHK Group shall be responsible for any liability with respect to any such claims or expenses.

(ii) Insured Benefits. With respect to benefits that, on or prior to the Distribution Date, were provided for under the CHK Welfare Plans through the purchase of insurance, CHK shall cause the CHK Welfare Plans to fully perform, pay and discharge all claims of SSE Welfare Plan Participants that were incurred prior to the Distribution Date.

(iii) Claims Incurred. For purposes of this Section 6.2(a), a claim or liability is deemed to be incurred (A) with respect to medical, dental, vision and/or prescription drug benefits, upon the rendering of health services giving rise to such claim or liability; (B) with respect to life insurance, accidental death and dismemberment and business travel accident insurance, upon the occurrence of the event giving rise to such claim or liability; (C) with respect to long-term disability benefits, upon the date of an individual’s disability, as determined by the disability benefit insurance carrier, giving rise to such claim or liability; and (D) with respect to a period of continuous hospitalization, upon the date of admission to the hospital, unless otherwise provided under the terms of the applicable CHK Welfare Plan.

(b) Credit for Deductibles and Other Limits. With respect to each SSE Welfare Plan Participant, the SSE Welfare Plans will give credit in plan year 2014 for any amount paid, number of services obtained or visits provided under the comparable type CHK Welfare Plan by such SSE Welfare Plan Participant in plan year 2014 toward deductibles, number of services or visits, or other similar permissible limitations to the extent such amounts are taken into account under the comparable type CHK Welfare Plan.

(c) COBRA. Effective as of the Distribution Date, SSE shall be responsible for COBRA with respect to all SSE Employees and Former SSE Employees. As of the effective date of the SSE Welfare Plan, SSE will satisfy all requirements under COBRA with respect to all SSE Employees under the SSE Welfare Plan.

Section 6.3 Continuity of Benefits, Benefit Elections and Beneficiary Designations.

(a) Benefit Elections and Designations. As of the Distribution Date (or such other date provided for under Section 6.3(b)), SSE shall cause the SSE Welfare Plans to recognize and

give effect to all elections and designations (including all coverage and contribution elections and beneficiary designations) made by each SSE Welfare Plan Participant under, or with respect to, the corresponding CHK Welfare Plan for plan year 2014.

(b) Additional Details Regarding Flexible Spending Accounts. Effective as of the Distribution Date, a Participating SSE Employer will establish under the SSE Welfare Plan a health care flexible spending account and/or dependent care flexible spending account (each a “SSE FSA”) for each SSE Welfare Plan Participant that has a health care flexible spending account and/or dependent care flexible spending account under the CHK Welfare Plan (each a “CHK FSA”) immediately prior to the Distribution Date. All activity under a SSE Welfare Plan Participant’s CHK FSA (that is, both contributions to and expenses paid from each account) for plan year 2014 through the Distribution Date shall be treated as activity under the corresponding SSE FSA, such that the SSE Welfare Plan Participant’s account balance in his SSE FSA on the Distribution Date will be equal to such participant’s CHK FSA balance immediately prior to the Distribution Date. A SSE Welfare Plan Participant’s CHK FSA salary reduction election will apply with respect to his SSE FSA for the portion of plan year 2014 beginning on the Distribution Date and ending on December 31, 2014 (the “Participation Period”). A SSE Welfare Plan Participant will continue to have access to his CHK FSA in accordance with its terms and conditions. Thus, the Parties agree that (i) all qualifying expenses incurred by a SSE Welfare Plan Participant during a Participation Period will be reimbursed under the SSE Welfare Plan Participant’s SSE FSA and (ii) all qualifying expenses incurred by the SSE Welfare Plan Participant for plan year 2014 prior to the Participation Period will be reimbursed under the SSE Welfare Plan Participant’s CHK FSA (in both cases in accordance with the applicable account’s terms and conditions and to the extent credits are available). Following the Distribution Date, with respect to the portion of plan year 2014 prior to the Participation Period, the Parties will determine and agree on the aggregate amount of SSE Welfare Plan Participants’ contributions to the CHK FSA (“Aggregate FSA Contribution Amount”) and the aggregate amount of SSE Welfare Plan Participants’ expenses incurred and reimbursed from the CHK FSA (“Aggregate FSA Expense Amount”). If the Aggregate FSA Expense Amount exceeds the Aggregate FSA Contribution Amount, SSE shall reimburse CHK for the total amount of the excess no later than 60 days after the Distribution Date; if the Aggregate FSA Contribution Amount exceeds the Aggregate FSA Expense Amount, CHK shall reimburse SSE for the total amount of the excess no later than 60 days after the Distribution Date. (For the avoidance of doubt, if the Aggregate FSA Contribution Amount exceeds the Aggregate FSA Expense Amount by $25,000, SSE will reimburse CHK $25,000 no later than 60 days after the Distribution Date.) After March 31, 2015, the Parties will determine and agree on the total amount of the reimbursements made to SSE Welfare Plan Participants from their CHK FSAs for qualifying expenses incurred prior to the Distribution Date and SSE will reimburse CHK for such amount as soon as reasonably practicable following March 31, 2015, but in no event later than April 30, 2015.

(c) Employer Non-elective Contributions. As of the Distribution Date, SSE shall cause any SSE Welfare Plan that constitutes a cafeteria plan under Section 125 of the Code to recognize and give effect to all non-elective employer contributions payable and paid toward coverage of a SSE Welfare Plan Participant under the corresponding CHK Welfare Plan that is a cafeteria plan under Section 125 of the Code for the applicable cafeteria plan year.

Section 6.4 Insurance Contracts. To the extent any CHK Welfare Plan is funded through the purchase of an insurance contract or is subject to any stop loss contract, CHK and SSE will cooperate and use their commercially reasonable efforts to replicate such insurance contracts for SSE (except to the extent changes are required under applicable state insurance laws) and to maintain any pricing discounts or other preferential terms for both CHK and SSE for a reasonable term under such contracts. Neither Party shall be liable for failure to obtain such pricing discounts or other preferential terms for the other Party under any insurance contracts. Each Party shall be responsible for any additional premiums, charges or administrative fees that such Party may incur pursuant to this Section 6.4.

Section 6.5 Third-Party Vendors. Except as provided below, to the extent any CHK Welfare Plan is administered by a third-party vendor, CHK and SSE will cooperate and use their commercially reasonable efforts to replicate any contract with such third-party vendor for SSE and to maintain any pricing discounts or other preferential terms for both CHK and SSE for a reasonable term with respect to such vendors. Neither Party shall be liable for failure to obtain such pricing discounts or other preferential terms for the other Party with respect to any third-party vendors. Each Party shall be responsible for any additional premiums, charges or administrative fees that such Party may incur pursuant to this Section 6.5.

ARTICLE VII

WORKERS’ COMPENSATION AND UNEMPLOYMENT COMPENSATION

Effective as of the Distribution Date, SSE shall have (and, to the extent it has not previously had such obligations, assume) the obligations for all claims and liabilities relating to workers’ compensation and unemployment compensation benefits for all SSE Employees and Former SSE Employees.

To the extent that assignment of such agreements is not permitted, effective as of the Distribution Date, each member of the SSE Group shall be considered to be a successor to each member of the CHK Group for purposes of, and a third-party beneficiary with respect to, all agreements containing restrictive covenants (including confidentiality and non-competition provisions) between a member of the CHK Group and a SSE Employee or Former SSE Employee whom SSE reasonably determines have substantial knowledge of the business activities of the SSE Group, such that each member of the SSE Group shall enjoy all the rights and benefits under such agreements (including rights and benefits as a third-party beneficiary), with respect to the business operations of the SSE Group; provided, however, that in no event shall CHK be permitted to enforce such restrictive covenant agreements against SSE Employees or Former SSE Employees for action taken in their capacity as employees of a member of the SSE Group.

Except as otherwise provided in this Agreement, on and after the Distribution Date, SSE shall assume, and be solely liable for, the handling, administration, investigation and defense of actions, including ERISA, occupational safety and health, employment standards, union grievances, wrongful dismissal, discrimination or human rights and unemployment compensation claims asserted at any time against CHK or any member of the CHK Group by any SSE Employee or Former SSE Employee (including any dependent or beneficiary of any such Employee) or any other person, to the extent such actions or claims arise out of or relate to employment or the provision of services (whether as an employee, contractor, consultant or otherwise) to or with respect to the business activities of any member of the SSE Group, whether or not such employment or services were performed before or after the Distribution. To the extent that any legal action relates to a putative or certified class of plaintiffs, which includes both CHK Employees (or Former CHK Employees) and SSE Employees (or Former SSE Employees) and such action involves employment or benefit plan related claims, reasonable costs and expenses incurred by the Parties in responding to such legal action shall be allocated among the Parties equitably in proportion to a reasonable assessment of the relative proportion of Employees included in or represented by the putative or certified plaintiff class. The procedures contained in the indemnification and related litigation cooperation provisions of the Master Separation Agreement shall apply with respect to each Party’s indemnification obligations under this Section 9.3.

Section 9.4 Reimbursement and Indemnification. CHK and SSE each agree to reimburse the other Party, within 60 days of receipt from the other Party of reasonable verification, for all costs and expenses which the other Party may incur on its behalf as a result of any of the respective CHK and SSE Welfare Plans (including, but not limited to, SSE’s reimbursement of CHK for all COBRA liabilities for SSE Employees and Former SSE

Employees), 401(k) Plan and, as contemplated by Section 8.2, any termination or severance payments or benefits. All liabilities retained, assumed or indemnified against by SSE pursuant to this Agreement, and all liabilities retained, assumed or indemnified against by CHK pursuant to this Agreement, shall in each case be subject to the indemnification provisions of the Master Separation Agreement. Notwithstanding anything to the contrary, (i) no provision of this Agreement shall require any member of the SSE Group to pay or reimburse to any member of the CHK Group any benefit-related cost item that a member of the SSE Group has previously paid or reimbursed to any member of the CHK Group; and (ii) no provision of this Agreement shall require any member of the CHK Group to pay or reimburse to any member of the SSE Group any benefit-related cost item that a member of the CHK Group has previously paid or reimbursed to any member of the SSE Group.

Section 9.5 Costs of Compliance with Agreement. Except as otherwise provided in this Agreement or any other Ancillary Agreement, each Party shall pay its own expenses in fulfilling its obligations under this Agreement.

Section 9.6 Fiduciary Matters. CHK and SSE each acknowledge that actions required to be taken pursuant to this Agreement may be subject to fiduciary duties or standards of conduct under ERISA or other applicable law, and no Party shall be deemed to be in violation of this Agreement if it fails to comply with any provisions hereof based upon its good faith determination (as supported by advice from counsel experienced in such matters) that to do so would violate such a fiduciary duty or standard. Each Party shall be responsible for taking such actions as are deemed necessary and appropriate to comply with its own fiduciary responsibilities and shall fully release and indemnify the other Party for any liabilities caused by the failure to satisfy any such responsibility.

Section 9.7 Form S-8. Before the Distribution or as soon as reasonably practicable thereafter and subject to applicable law, SSE shall prepare and file with the SEC a registration statement on Form S–8 (or another appropriate form) registering under the Securities Act of 1933 the offering of a number of shares of SSE Common Stock at a minimum equal to the number of shares subject to the Replacement SSE Options, the Replacement SSE RSUs and the Replacement SSE RSAs. SSE shall use commercially reasonable efforts to cause any such registration statement to be kept effective (and the current status of the prospectus or prospectuses required thereby shall be maintained) as long as any Replacement SSE Options, Replacement SSE RSUs, or Replacement SSE RSAs may remain outstanding.

Section 9.8 Entire Agreement. This Agreement, together with the documents referenced herein (including the Master Separation Agreement, the Ancillary Agreements and the plans and agreements referenced herein), constitutes the entire agreement and understanding among the Parties with respect to the subject matter hereof and supersedes all prior written and oral and all contemporaneous oral agreements and understandings with respect to the subject matter hereof. To the extent any provision of this Agreement conflicts with the provisions of the Master Separation Agreement, the provisions of this Agreement shall be deemed to control with respect to the subject matter hereof.

Section 9.9 Binding Effect; No Third-Party Beneficiaries; Assignment. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective

successors and permitted assigns. Except as otherwise expressly provided in this Agreement, this Agreement is solely for the benefit of the Parties and should not be deemed to confer upon any third parties any remedy, claim, liability, reimbursement, cause of action or other right in excess of those existing without reference to this Agreement. Nothing in this Agreement is intended to amend any employee benefit plan or affect the applicable plan sponsor’s right to amend or terminate any employee benefit plan pursuant to the terms of such plan. Except as otherwise provided in Section 8.1(a), the provisions of this Agreement are solely for the benefit of the Parties, and no current or former Employee, officer, director or independent contractor or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of this Agreement. This Agreement may not be assigned by any Party, except with the prior written consent of the other Parties.

Section 9.10 Amendment; Waivers. No change or amendment may be made to this Agreement except by an instrument in writing signed on behalf of each of the Parties. Any Party may, at any time, (i) extend the time for the performance of any of the obligations or other acts of another Party, (ii) waive any inaccuracies in the representations and warranties of another Party contained herein or in any document delivered pursuant hereto, and (iii) waive compliance by another Party with any of the agreements, covenants or conditions contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the Party to be bound thereby. No failure or delay on the part of any Party in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty, covenant or agreement contained herein, nor shall any single or partial exercise of any such right preclude other or further exercises thereof or of any other right.

Section 9.11 Remedies Cumulative. All rights and remedies existing under this Agreement or the Schedules attached hereto are cumulative to, and not exclusive of, any rights or remedies otherwise available.

Unless otherwise expressly provided herein, all notices, claims, certificates, requests, demands and other communications hereunder shall be in writing and shall be deemed to be duly given: (i) when personally delivered, (ii) if mailed by registered or certified mail, postage prepaid, return receipt requested, on the date the return receipt is executed or the letter is refused by the addressee or its agent, (iii) if sent by overnight courier which delivers only upon the executed receipt of the addressee, on the date the receipt acknowledgment is executed or refused by the addressee or its agent, or (iv) if sent by facsimile or electronic mail, on the date confirmation of transmission is received (provided that a copy of any notice delivered pursuant to this clause (iv) shall also be sent pursuant to clause (i), (ii) or (iii)), addressed to the attention of the addressee’s General Counsel at the address of its principal executive office or to such other address or facsimile number for a Party as it shall have specified by like notice.

Section 9.14 Severability. If any term or other provision of this Agreement or the Schedules attached hereto is determined by a nonappealable decision by a court, administrative agency or arbitrator to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the court, administrative agency or arbitrator shall interpret this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible. If any sentence in this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.
