Effective no later than the Distribution Time, SpinCo shall assume all Liabilities for SpinCo Employees, SpinCo Independent Contractors and Former SpinCo Service Providers related to any and all workers’ compensation injuries, incidents, conditions, claims or coverage, whenever incurred (including claims incurred prior to the Distribution Time but not reported until after the Distribution Time), and SpinCo shall be fully responsible for the administration, management and payment of all such claims and satisfaction of all such Liabilities. Notwithstanding the foregoing, if SpinCo is unable to assume any such Liability or the administration, management or payment of any such claim solely because of the operation of applicable Law, the Company shall retain such Liabilities and SpinCo shall reimburse and otherwise fully indemnify the Company for all such Liabilities, including the costs of administering the plans, programs or arrangements under which any such Liabilities have accrued or otherwise arisen.
5.5 COBRA Compliance. The Company shall retain responsibility for compliance with the health care continuation requirements of COBRA with respect to SpinCo Employees or Former SpinCo

Service Providers who, as of the Plan Transition Date, were covered under a Company Benefit Plan or who had incurred a COBRA qualifying event and were eligible to elect COBRA under a Company Benefit Plan. SpinCo shall be responsible for administering compliance with the health care continuation requirements of COBRA, and the corresponding provisions of the SpinCo Benefit Plans with respect to SpinCo Employees and their covered dependents who incur a COBRA qualifying event or loss of coverage at any time after the Plan Transition Date.
5.6 Code Section 409A. Notwithstanding anything in this Agreement to the contrary, the Parties shall negotiate in good faith regarding the need for any treatment different from that otherwise provided herein with respect to the payment of compensation to ensure that the treatment of such compensation does not cause the imposition of a Tax under Section 409A of the Code. In no event, however, shall any Party be liable to another in respect of any Taxes imposed under, or any other costs or Liabilities relating to, Section 409A of the Code.
5.7 Payroll Taxes and Reporting. The Parties shall, to the extent practicable, (i) treat SpinCo or a member of the SpinCo Group as a “successor employer” and the Company (or the appropriate member of the Company Group) as a “predecessor,” within the meaning of Sections 3121(a)(1) and 3306(b)(1) of the Code, with respect to SpinCo Employees for purposes of Taxes imposed under the United States Federal Unemployment Tax Act or the United States Federal Insurance Contributions Act, and (ii) cooperate with each other to avoid, to the extent reasonably practicable, the filing of more than one IRS Form W-2 with respect to each SpinCo Employee for the calendar year in which the Distribution Time occurs.
5.8 Regulatory Filings. Subject to applicable Law and the Tax Matters Agreement, the Company shall retain responsibility for all employee-related regulatory filings for reporting periods ending at or prior to the Distribution 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 Company shall provide data and information (to the extent permitted by applicable Laws) to SpinCo, which shall be responsible for making such filings in respect of SpinCo Employees.
5.9 Certain Requirements. Notwithstanding anything in this Agreement to the contrary, if applicable Law requires that any assets or Liabilities be retained by the Company Group or transferred to or assumed by the SpinCo 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 applicable Law and shall not be made as otherwise set forth in this Agreement and the Parties shall reasonably cooperate to adjust for any related economic consequences.

On and after the Distribution Time, the Parties shall, or shall cause each of their respective Affiliates to, make available to each other those of their employees who may reasonably be needed in order to defend or prosecute any legal or administrative action (other than a legal action among the Parties) to which any employee or director of the Company Group or the SpinCo Group or any Company Benefit Plan or SpinCo Benefit Plan is a party and which relates to a Company Benefit Plan or SpinCo Benefit Plan.

7.8 Audit Rights With Respect to Information Provided.
(a) Each Party, and their duly authorized representatives, shall have the right to conduct reasonable audits with respect to all information required to be provided to it by the other Parties under this Agreement.

The Auditing Party shall be responsible for supplying, at the Auditing Party’s expense, additional personnel sufficient to complete the audit in a reasonably timely manner.

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 Distribution Time, to the extent such Subsidiary remains a Subsidiary of the applicable Party.
8.10 Title and Headings. Titles and headings to sections herein are inserted for the convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.
8.11 Governing Law. This Agreement, and all claims, disputes, controversies or causes of action (whether in contract, tort, equity or otherwise) that may be based upon, arise out of or relate to this Agreement (including any schedule or exhibit hereto) or the negotiation, execution or performance of this Agreement (including any claim, dispute, controversy 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), shall be governed by and construed in accordance with the Laws of the State of Delaware, without regard to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. Each of the Parties agrees that any Action related to this agreement shall be brought exclusively in the Chosen Courts. By executing and delivering this Agreement, each of the Parties irrevocably: (a) accepts generally and unconditionally submits to the exclusive jurisdiction of the Chosen Courts for any Action relating to this Agreement; (b) waives any objections which such party may now or hereafter have to the laying of venue of any such Action contemplated by this Section 8.11 and hereby further irrevocably waives and agrees not to plead or claim that any such Action has been brought in an inconvenient forum; (c) agrees that it will not attempt to deny or defeat the personal jurisdiction of the Chosen Courts by motion or other request for leave from any such court; (d) agrees that it will not bring any Action contemplated by this Section 8.11 in any court other than the Chosen Courts; (e) agrees that service of all process, including the summons and complaint, in any Action may be made by registered or certified mail, return receipt requested, to such party at their respective addresses provided in accordance with Section 8.4 or in any other manner permitted by Law; and (f) agrees that service as provided in the preceding clause (e) is sufficient to confer personal jurisdiction over such party in the Action, and otherwise constitutes effective and binding service in every respect. Each of the parties hereto agrees that a final judgment in any Action in a Chosen Court as provided above may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law, and each party further agrees to the non-exclusive jurisdiction of the Chosen Courts for the enforcement or execution of any such judgment.

8.12 WAIVER OF JURY TRIAL. THE PARTIES HEREBY UNCONDITIONALLY AND IRREVOCABLY WAIVE THEIR RIGHT TO TRIAL BY JURY IN ANY JUDICIAL PROCEEDING IN ANY COURT RELATING TO ANY DISPUTE, CONTROVERSY OR CLAIM ARISING OUT OF, RELATING TO OR IN CONNECTION WITH THIS AGREEMENT (INCLUDING ANY SCHEDULE OR EXHIBIT HERETO) OR THE BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS AGREEMENT. NO PARTY TO THIS AGREEMENT SHALL SEEK A JURY TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM OR ANY OTHER LITIGATION PROCEDURE BASED UPON, OR ARISING OUT OF, THIS AGREEMENT OR ANY RELATED INSTRUMENTS. NO PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. EACH PARTY TO THIS AGREEMENT CERTIFIES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR INSTRUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS SET FORTH ABOVE IN THIS SECTION 8.12. NO PARTY HAS IN ANY WAY AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS SECTION 8.12 WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.
8.13 Severability. If any provision of this Agreement, or the application of any such provision to any Person or circumstance, shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties.
8.14 Interpretation. The Parties have participated jointly in the negotiation and drafting of this Agreement. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the Party drafting or causing any instrument to be drafted.
8.15 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.
8.16 No Waiver. No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder shall operate as a waiver hereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.
8.17 No Admission of Liability. The allocation of Assets and Liabilities herein is solely for the purpose of allocating such Assets and Liabilities among the Parties and is not intended as an admission of liability or responsibility for any alleged Liabilities vis-à-vis any third party, including with respect to the Liabilities of any non-wholly owned subsidiary of any Party.
