If and only if (a) all conditions set forth in Section 7.1 and Section 7.2 of the Merger Agreement have been satisfied or waived (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or waiver (to the extent permitted under the Merger Agreement) of such conditions) and the Closing is required to occur pursuant to Section 1.3 of the Merger Agreement, (b) the Company has irrevocably confirmed in writing that if the Equity Financing is funded, then the Company will take such actions that are required of it by the Merger Agreement to consummate the Closing pursuant to the terms of the Merger Agreement and (c) substantially concurrently, Parent has received the funds pursuant to certain other equity commitment letters (the “Other Investor Equity Commitment Letters” and the equity financing pursuant thereto, the “Other Investor Equity Financing”), dated as of the date hereof, by and between Parent and certain other investors (the “Other Investors”), each of the undersigned (each, an “Investor” and, collectively, the “Investors”) hereby severally (and not jointly or jointly and severally) agrees that, at and subject to the consummation of the Closing, it will contribute, or cause to be contributed to Parent (directly, or indirectly through one or more parent companies of Parent, or otherwise), an amount, in immediately available funds, equal to the product of such Investor’s respective “Commitment Percentage” set forth opposite such Investor’s name on Schedule A attached hereto multiplied by $650,000,000 (each such Investor’s respective commitment to Parent, its “Equity Commitment”), which Equity Commitment shall be used by Parent, together with the proceeds of the Other Investors’ Equity Commitments and Other Investor Equity Financing, to pay the Required Amounts at the Closing, in each case, on the terms and subject to the conditions of the Merger Agreement and not for any other purpose; provided that, no Investor shall, under any circumstances, be obligated to contribute to Parent more than its Equity Commitment; provided, however, that the satisfaction or failure of the condition set forth in clause (c) of this Section 1 shall not limit or impair the ability of the Company to enforce the obligations of Parent under, and in accordance with, Section 3 of this Commitment Letter if either (i) the Company is also seeking enforcement of each Other Investor’s Other Investor Equity Financing under Section 3 of such Other Investor’s Equity Commitment Letter or (ii) each Other Investor has satisfied and performed, or has irrevocably confirmed in writing that it is prepared to satisfy and perform, in full, its obligations with respect to such Other Investor’s Other Investor Equity Financing under such Other Investor’s Other Investor Equity Commitment Letter (but with any actual performance by the Investors hereunder subject in each case to each Other Investor’s satisfaction and performance in full of its obligations with respect to such Other Investor’s Equity Financing under such Other Investor’s Other Investor Equity Commitment Letter and in no event will an Investor be required to fund all or any portion of its Equity Commitment unless each Other Investor satisfies and performs in full such obligations with respect to such Other Investor’s Other Investor Equity Financing.

2.

3. This Commitment Letter shall be binding solely on each Investor and inure solely to the benefit of Parent, and nothing set forth in this Commitment Letter (other than as set forth in this Section 3 and in Section 7 hereof) shall be construed to confer upon or give to any Person other than Parent any benefits, rights or remedies under or by reason of, or any rights to enforce or cause Parent to enforce, any Investor’s respective Equity Commitment or any other provisions of this Commitment Letter; provided, however, that, upon the terms and subject to the conditions of the Merger Agreement, including, without limitation, Section 9.5(b) thereof, the Company is hereby expressly made a third party beneficiary of the rights granted Parent hereby only for the purpose of seeking specific performance of Parent’s right to cause the Equity Commitment to be funded by each of the Investors under Section 1 hereunder (solely to the extent that Parent can enforce such Equity Commitments pursuant to the terms hereof), and for no other purpose (including, without limitation, any claim for monetary damages hereunder).

Neither the Investors nor Parent may assign its rights, interests or obligations hereunder to any other Person (except by operation of law) without the prior written consent of Parent (in the case of an assignment by the Investors) or the Investors (in the case of an assignment by Parent); provided, however, that each Investor may assign all or a portion of its rights, interests or obligations to any co-investor, any Affiliate, any fund managed or otherwise controlled by or under common control with such Investor or any other Person (provided that any such assignment shall not relieve such Investor of its obligations hereunder unless and to the extent actually performed). Any attempted assignment in violation of this section shall be null and void.

5. Notwithstanding anything that may be expressed or implied in this Commitment Letter or any document or instrument delivered contemporaneously herewith, and notwithstanding the fact that any Investor may be a limited partnership or limited liability company, Parent, by its acceptance of the benefits of this Commitment Letter, covenants, agrees and acknowledges that no Person other than the Investors shall have any obligation under this Commitment Letter and no claim may be asserted against any other Person that is not a Permitted Claim. Accordingly, Parent agrees that, except as set forth in the immediately preceding sentence, it has no rights of recovery against, and no recourse hereunder or under any documents or instruments delivered in connection herewith or in respect of any oral representations made or alleged to be made in connection herewith or therewith, shall be had against, any former, current or future director, officer, agent, Affiliate, member, general or limited partner, manager, assignee, equityholder or employee of an Investor (or any of their successors or permitted assignees), or any Affiliate thereof or against any former, current or future director, officer, agent, employee, Affiliate, assignee, general or limited partner, equityholder, manager or member (or any of their successors or permitted assigns) of any of the foregoing (each, an “Investor/Parent Affiliate”), whether by or through attempted piercing of the corporate veil, by or through an Action (whether in tort, contract or otherwise) by or on behalf of Parent against the Investor/Parent Affiliates, by the enforcement of any judgment or assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law, or otherwise. The parties hereto expressly agree and acknowledge that no personal liability whatsoever shall attach to, be imposed on, or otherwise be incurred by any Investor/Parent Affiliate (other than the Investors, Parent or Stone Point with respect to any applicable Permitted Claim), as such, for any obligations of the Investors under this Commitment Letter or the transactions contemplated hereby, under any documents or instruments delivered in connection herewith, in respect of any oral representations made or alleged to be made in connection herewith or therewith, or for any claim (whether at law or in equity, in tort, contract or otherwise) based on, in respect of, or by reason of, such obligations or their creation.

6. Parent further agrees that neither it nor any of its Affiliates shall have any right of recovery against any of the Investors or any Investor/Parent Affiliate, whether by piercing of the corporate veil, by a claim on behalf of Parent against any Investor or any Investor/Parent Affiliate, or otherwise, except for Parent’s right to be funded by such Investor under and to the extent provided in this Commitment Letter and subject to the terms and conditions hereof and of the Merger Agreement. Parent hereby covenants and agrees that it shall not institute, and shall cause its Affiliates not to institute, any Action (whether at law or in equity, in tort, contract or otherwise) arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby, or in respect of any oral representations made or alleged to be made in connection therewith, against any Investor or any Investor/Parent Affiliate, except for an Action to enforce Parent’s right to cause the Equity Commitment to be funded by each of the Investors under Section 1 hereunder.

7. Concurrently with the execution and delivery of this Commitment Letter, the Investors are executing and delivering to the Company the Investor Limited Guarantee related to certain payment obligations of Parent under the Merger Agreement. The Company’s remedies against an Investor under the Investor Limited Guarantee, subject to the express terms and conditions thereof, shall, and are intended to, be the exclusive remedy available to the Company and its Affiliates against such Investor or any of its Investor/Parent Affiliates in respect of any liabilities or obligations arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby, or in respect of any oral representations made or alleged to be made in connection therewith, including in the event Parent breaches its obligations under the Merger Agreement, whether or not any such breach is caused by such Investor’s breach of its obligations under this Commitment Letter, except for the right of Parent or the Company to specifically enforce the provisions of this Commitment Letter to cause such Investor to contribute to Parent, or cause to be contributed to Parent, an aggregate amount of the Equity Commitment, upon the terms and subject to the conditions set forth in this Commitment Letter and the Merger Agreement.

8. Each party hereto hereby represents and warrants, with respect to itself, to each other party that (a) it is duly organized, validly existing and in good standing under the Laws of the jurisdiction of its formation; (b) it has all necessary power and authority to execute, deliver and perform this Commitment Letter in accordance with the terms hereof; (c) the execution, delivery and performance of this Commitment Letter have been duly authorized by all necessary action and do not conflict with, contravene or result in any default, breach, violation or infringement (with or without notice or lapse of time or both) of any provision of such party’s charter, partnership agreement, operating agreement or similar organizational documents or any law, regulation, rule, decree, order or judgment; and (d) this Commitment Letter constitutes a legal, valid and binding obligation of such party enforceable against such party in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar Laws affecting creditors’ rights generally, and (ii) general equitable principles (whether considered in a proceeding in equity or at law). Each Investor hereby represents and warrants to Parent that it has the financial capacity to pay and perform its obligations under this Commitment Letter, and all funds necessary for it to fulfill its obligations hereunder shall be available to it on a timely basis for so long as this Commitment Letter shall remain in effect in accordance with Section 2 hereof.

All counterparts shall be construed together and shall constitute one and the same instrument. In addition, facsimile or PDF signatures of authorized signatories of any party shall be valid and binding and delivery of a facsimile or PDF signature by any party shall constitute due execution and delivery of this Commitment Letter.

Each of the parties hereto irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Action relating to this Commitment Letter, for and on behalf of itself or any of its properties or assets, in such manner as may be permitted by applicable Law.
