Subject to applicable Legal Requirements and the Tax Matters Agreement, Everest shall retain responsibility for all employee-related regulatory filings for reporting periods ending at or prior to the Separation Effective Time, except for Equal Employment Opportunity Commission EEO-1 reports and affirmative action program (AAP) reports and responses to Office of Federal Contract Compliance Programs (OFCCP) submissions, for which the Parties shall cooperate in good faith to provide data and information (to the extent permitted by applicable Legal Requirements) to Newco, which shall be responsible for making such filings in respect of Newco Employees.

Section 5.9 Disability.

(a) Except as required by applicable Legal Requirements and notwithstanding any provision of Section 2.5 or Section 3.1(a) to the contrary, to the extent any Newco Welfare Plan is underwritten to only cover disability claims incurred following the Separation Effective Time, with respect to any Newco Employee that has, as of the Separation Effective Time, incurred a claim as part of any short- or long-term disability program under an Everest Welfare Plan, such Newco Employee’s rights to continued short- or long-term disability benefits shall remain with, and be according to the terms of, the applicable Everest Welfare Plan as of the Separation Effective Time and to the extent such Newco Employee is able to return to work within twelve (12) months of the disability event, Newco shall provide a qualifying offer of employment to such Newco Employee in accordance with Section 2.2; provided, that to the extent the applicable Newco Welfare Plan accepts claims incurred prior to the Separation Effective Time, such claims shall transfer to a Newco Welfare Plan on or before the Separation Effective Time, and the remainder (if any) of such Transferred Newco Employee’s short- or long-term disability benefits will be paid by a Newco Welfare Plan. If the claims described in the first sentence of this Section 5.9(a) transfer to a Newco Welfare Plan effective on or before the Separation Effective Time and if any Newco Employee described above shall have any dispute with such benefits that such Newco Employee is receiving or has filed a claim to receive under a Newco Welfare Plan, any and all appeal rights of such Newco Employee shall be realized through the Newco Welfare Plans (and any appeal rights such Newco Employee may have under any Everest Welfare Plan will be limited to benefits received and time periods occurring prior to the Separation Effective Time). If the claims described in the first sentence of this Section 5.9(a) do not transfer to a Newco Welfare Plan effective as of the Separation Effective Time, then a member of the Newco Group shall promptly reimburse the Everest Welfare Plan for the cost of such continued coverage.

(b) For any Newco Employee or Former Newco Service Provider who is, as of the Separation Effective Time, receiving payments as part of any short- or long-term disability program that is part of an Everest Welfare Plan, and has been receiving short- or long-term disability payments from such plan for twelve (12) months or fewer before the Separation Effective Time, and to the extent such Newco Employee or Former Newco Service Provider is able to return to work within twelve (12) months of the disability event, Newco shall provide a qualifying offer of employment to such Newco Employee or Former Newco Service Provider in accordance with Section 2.2; provided, however that, notwithstanding the foregoing, no Newco Employee or Former Newco Service Provider described in this Section 5.9(b) will be eligible for re-employment as described in this subsection after the first anniversary of the Separation Effective Time.

Section 5.10 Certain Requirements. Notwithstanding anything in this Agreement to the contrary, if the Transfer Regulations, the terms of a Collective Bargaining Agreement or applicable Legal Requirements require that any Assets or Liabilities be retained by the Everest Group or transferred to or assumed by the Newco Group in a manner that is different from that set forth in this Agreement, such retention, transfer or assumption shall be made in accordance with the terms of such Collective Bargaining Agreement or applicable Legal Requirement and shall not be made as otherwise set forth in this Agreement.

28

Section 5.11 Fiduciary Matters. The Parties 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 Legal Requirement, 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. Subject to Section 5.6, 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 5.12 No Hire and No Solicitation of Employees. Everest and Athena each agree that, except as specifically set forth below, for a period of (i) twenty-four (24) months for those Key Everest Employees in compensation band E3 and for those Key Athena Employees in compensation bands N, N-1 and N-2 and (ii) eighteen (18) months for each other Key Everest Employee and Key Athena Employee, in either case, from and after the Closing Date (the “Non-Solicit Period”), without the prior written consent of the other applicable party, they shall not, and they shall cause their respective Subsidiaries not to, directly or indirectly, hire or solicit to hire (or cause or seek to cause to leave the employ of the other party or the other party’s Subsidiary), or solicit to enter, or enter into, a consulting agreement with, any employee who is a Key Everest Employee or Key Athena Employee on the Closing Date, as applicable. The restrictions set forth in this Section 5.12 shall not apply to (i) any Key Everest Employee or Key Athena Employee whose employment has been involuntarily terminated by a party or a party’s Subsidiary without cause, including in connection with a layoff or reduction in force; or (ii) Key Everest Employee or Key Athena Employee who has voluntarily terminated his or her employment with a party or a party’s Subsidiary, after six (6) months from the date of termination of such employee’s employment, or such longer period as required by applicable law.

ARTICLE VI

GENERAL AND ADMINISTRATIVE

Section 6.1 Employer Rights. Nothing in this Agreement shall be deemed to be an amendment to any Everest Benefit Arrangement or Newco Benefit Arrangement or to prohibit any member of the Everest Group or Newco Group, as the case may be, from amending, modifying or terminating any Everest Benefit Arrangement or Newco Benefit Arrangement at any time within its sole discretion.

Section 6.8 Employee Benefits Administration.

This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument.

Section 7.4 Waiver.

(a) No failure on the part of any Party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. The rights and remedies hereunder are cumulative and not exclusive of any rights or remedies that any Party would otherwise have.

32

(b) No Party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

Section 7.5 Assignment. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any Party’s rights or obligations hereunder may be assigned or delegated by such Party without the prior written consent of the other Parties, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by any Party without the prior written consent of the other Parties shall be void and of no effect.

Section 7.6 Termination. This Agreement shall terminate without further action at any time before the Separation Effective Time upon termination of the Merger Agreement. If so terminated, no Party shall have any Liability of any kind to any other Party or any other Person on account of this Agreement, except as provided in the Merger Agreement.

Section 7.7 Amendment. This Agreement may not be amended except by an instrument in writing signed by an authorized Representative of each of the Parties.

Section 7.8 Subsidiaries. Each of the Parties shall cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary of such Party or by any Entity that becomes a Subsidiary of such Party at and after the Separation Effective Time, to the extent such Subsidiary remains a Subsidiary of the applicable Party.

Section 7.9 Governing Law; Jurisdiction; Specific Performance; Remedies. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any Legal Proceeding between any of the Parties arising out of or relating to this Agreement or any of the transactions contemplated hereby: (a) each of the Parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, if under applicable Legal Requirements, exclusive jurisdiction over such matter is vested in the federal courts, any federal court in the State of Delaware and any appellate court from any thereof; (b) each of the Parties irrevocably waives the right to trial by jury; and (c) each of the Parties irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, any claim (i) that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason; (ii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts; and (iii) that (x) the claim, action, suit or other Legal Proceeding in any such court is brought in an inconvenient forum; (y) the venue of such claim, action, suit or other Legal Proceeding is improper; or (z) this Agreement or the subject matter hereof may not be enforced in or by such courts. Each of the Parties further agrees that, to the fullest extent permitted by applicable Legal Requirements, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in Section 7.3 will be effective service of process for any claim, action, suit or other Legal Proceeding in the Court of Chancery of the State of Delaware or, to

33

the extent required by Legal Requirements, any federal court in the State of Delaware, with respect to any matters to which it has submitted to jurisdiction as set forth in this paragraph. The Parties hereby agree that a final judgment in any such claim, suit, action or other Legal Proceeding will be conclusive, subject to any appeal, and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements. The Parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to specific performance and injunctive or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without the requirement for the posting of any bond, this being in addition to any other remedy to which they are entitled at law or in equity. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

Section 7.10 Severability. Any term or provision of this Agreement (or part thereof) that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision (or part thereof) in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement (or part thereof) is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit such term or provision (or part thereof), to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision (or part thereof), and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision (or part thereof) with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

Section 7.11 No Duplication; No Double Recovery. Nothing in this Agreement is intended to confer to or impose upon any Party a duplicative right, entitlement, obligation or recovery with respect to any matter arising out of the same facts and circumstances.

Section 7.12 Tax Treatment of Payments. The Parties agree that any payment made among the Parties pursuant to this Agreement shall be treated, to the extent permitted by applicable Legal Requirement, for all U.S. federal income tax purposes as either (i) a non-taxable contribution by Everest to Newco, or (ii) a distribution by Newco to Everest, in each case, made immediately prior to the Distribution. Any such payment made by a Party under this Agreement shall be increased as necessary so that after making all payments in respect to Taxes imposed on or attributable to such payment, the recipient Party receives an amount equal to the sum it would have received had no such Taxes been imposed.

In the event of any inconsistency or conflict which may arise in the application or interpretation of any of the definitions set forth in Section 1.1, for the purpose of determining what is and is not included in such definitions, any item explicitly included on a Schedule referred to in any such definition shall take priority over any provision of the text thereof.

Section 7.14 Relation to Other Documents. To the extent there is any inconsistency between this Agreement and the terms of another agreement pertaining to the Distribution or Mergers (other than any Collective Bargaining Agreement) that is the subject of this Agreement and such inconsistency (i) arises in connection with or as a result of employment with or the performance of services before or after the Distribution for any member of the Athena Group, Everest Group or Newco Group and (ii) relates to the allocation of Liabilities attributable to the employment, service, termination of employment or termination of service of all present or former Everest Employees or Newco Employees or any of their dependents and beneficiaries (and any alternate payees in respect thereof) and other service providers (including any individual who is, or was or is determined to be an independent contractor, temporary employee, temporary service worker, consultant, freelancer, agency employee, leased employee, on-call worker, incidental worker, or non-payroll worker or in any other employment, non-employment, or retainer arrangement, or relationship with any member of the Everest Group or the Newco Group), the terms of this Agreement shall prevail.
