1.Voting of Shares.

(a)From the period commencing with the execution and delivery of this Agreement and continuing until the Expiration Date, at every meeting of the shareholders of Parent (whether annual, special or otherwise) however called with respect to any of the following, and at every adjournment or postponement thereof, and on every action or approval by written consent of the shareholders of Parent proposed by Parent with respect to any of the following, when a meeting is held, the Shareholder shall appear at such meeting (in person or by proxy) or otherwise cause the Subject Shares to be counted as present thereat for the purpose of establishing a quorum and shall vote or cause to be voted the Subject Shares that the Shareholder is entitled to vote, and when a written consent is proposed, respond to each request by Parent for written consent and consent (a) in favor of the approval of the Share Issuance and any other matters necessary or reasonably requested by the Company for the approval of the Share Issuance and (b) against any other action or agreement that would reasonably be expected to (i) result in a breach of any covenant, representation or warranty or any other obligation or agreement of Parent under the Merger Agreement, (ii) result in any of the conditions to the consummation of the Merger under the Merger Agreement not being fulfilled or (iii) impede, frustrate, interfere with, delay, postpone or adversely affect the Merger and the other transactions contemplated by the Merger Agreement.

(b)From the period commencing with the execution and delivery of this Agreement and continuing until the Expiration Date, without limiting the obligations of the Shareholder under this Agreement, the Shareholder hereby irrevocably appoints as its proxy and attorney-in-fact the officers of the Company set forth on Annex A hereto, and any individual who shall hereafter succeed to any such officer of the Company, and any other Person designated in writing by the Company (collectively, the “Proxy Holders”), each of them individually, with full power of substitution, to vote the Subject Shares in accordance with Section 1(a); provided that the proxy and the power of attorney granted by the Shareholder shall be effective if, and only if, the Shareholder has not delivered to Parent at least three (3) Business Days prior to the date of any applicable meeting of the shareholders of Parent (or, as applicable, any adjournments or postponements thereof), a duly executed proxy card voting the Shareholder’s Subject Shares in accordance with Section 1(a) and has not revoked such duly executed proxy card. This proxy is coupled with an interest and shall be irrevocable, and the Shareholder shall take such further action or execute such other instruments as may be reasonably necessary to effectuate the intent of this proxy and hereby revokes any proxy previously granted by the Shareholder with respect to the Subject Shares. This proxy and the power of attorney is given by the Shareholder in connection with, and in consideration of, the execution of the Merger Agreement by Parent and to secure the performance of the duties of the Shareholder under this Agreement. The power of attorney granted by the Shareholder herein is a

2

durable power of attorney and shall survive the dissolution or bankruptcy of the Shareholder. The irrevocable proxy granted hereunder shall automatically terminate upon the Expiration Date.

2.Transfer of Shares.

(a)The Shareholder covenants and agrees that during the period from the date of this Agreement until the Expiration Date, the Shareholder will not, directly or indirectly, (i) transfer, assign, sell, pledge, encumber, hypothecate or otherwise dispose (whether by sale, liquidation, dissolution, dividend or distribution) of or consent to any of the foregoing (“Transfer”), or cause to be Transferred, any of the Subject Shares, (ii) deposit any of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Subject Shares or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement, (iii) enter into any contract, option or other arrangement or undertaking with respect to the Transfer of any Subject Shares or (iv) take any other action or enter into any agreement or undertaking that would reasonably be expected to restrict, limit or interfere with the performance of the Shareholder’s obligations hereunder. The foregoing restrictions on Transfers of Subject Shares shall not prohibit any such Transfers by the Shareholder in connection with the transactions contemplated by the Merger Agreement. Notwithstanding the foregoing, the Shareholder may Transfer the Subject Shares by will, for estate planning purposes, or to any of Shareholder’s controlled Affiliates (such Persons, collectively, the “Permitted Transferee”), in each case, provided that (A) the Subject Shares shall continue to be bound by this Agreement following such Transfer and (B) each Permitted Transferee that is not a party hereto agrees in writing to be bound by the terms and conditions of this Agreement. Notwithstanding the restrictions set forth herein, if, between the date hereof and the Expiration Date, the Shareholder shall be deemed to own more than 9.9% of the outstanding Parent Shares, including as a result of any stock repurchases by Parent, stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or similar transaction, the Shareholder may Transfer the number of Subject Shares so deemed to be owned by it in excess of 9.9% of the outstanding Parent Shares such that, immediately following such Transfer, the Shareholder owns 9.9% of the outstanding Parent Shares.

(b)At all times commencing with the execution and delivery of this Agreement and continuing until the Expiration Date, in furtherance of this Agreement, the Shareholder hereby authorizes Parent or its counsel to notify Parent’s transfer agent that there is a stop transfer order with respect to all of the Subject Shares (and that this Agreement places limits on the voting and Transfer of the Subject Shares). Parent shall not register, or permit Parent’s transfer agent to register, a Transfer of any of the Subject Shares in violation of this Agreement. Parent shall immediately withdraw and terminate any such stop transfer order and notice following the Expiration Date.

3.Acquisition Proposals. The Shareholder shall not, and shall cause its general partners, directors, executive officers and employees not to, and shall direct its

3

other Representatives not to, directly or indirectly, (a) solicit, initiate, induce or knowingly facilitate the making of any proposal that constitutes, or would reasonably be likely to lead to, a Parent Alternative Proposal, (b) engage in or otherwise participate in any discussions or negotiations with any other Person regarding, or furnish to any other Person any material non-public information for the purpose of facilitating, a Parent Alternative Proposal or (c) approve or recommend, make any public statement approving or recommending, or enter into any agreement relating to, any inquiry, proposal or offer that constitutes or would reasonably be expected to lead to a Parent Alternative Proposal, and the Shareholder shall not, alone or together with any other Person, make a Parent Alternative Proposal (the actions described in clause (a), (b) and (c), collectively, the “Restricted Activities”). Notwithstanding the foregoing, to the extent that Parent or the Parent Board is permitted to engage in any Restricted Activities pursuant to Section 5.03 of the Merger Agreement, the Shareholder may participate in such Restricted Activities; provided that such action by the Shareholder would be permitted to be taken by Parent or the Parent Board pursuant to Section 5.03 of the Merger Agreement.

For the avoidance of doubt, any securities of Parent that are subject to the foregoing lock-up agreement shall be eligible for participation in any share repurchase program conducted by Parent; provided, that any such securities are sold directly to Parent. For purposes of this Section 4, “Lock-Up Period” means the period from the date hereof through and including (i) the 225^th day following the date hereof with respect to one-third of the Subject Shares held or beneficially owned by the Shareholder on the date hereof, (ii) the 365^th day following the date hereof with respect to one-third of the Subject Shares held or beneficially owned by the Shareholder on the date hereof and (iii) the 450^th day following the Closing Date with respect to one-third of the Subject Shares held or beneficially owned by the Shareholder; provided, further, that the Shareholder and its Affiliates may request that Parent release additional Subject Shares from the applicable Lock-Up Period (such consent not to be unreasonably withheld or delayed) in order to facilitate an orderly sell-down of Subject Shares by the Shareholder and its Affiliates. Notwithstanding the foregoing, if during any Lock-Up Period the Shareholder shall be deemed to own more than 9.9% of the outstanding Parent Shares, including as a result of any stock repurchases by Parent, stock dividend, subdivision, reclassification,

4

recapitalization, split, combination, exchange of shares or similar transaction, the Shareholder may Transfer the number of Subject Shares so deemed to be owned by it in excess of 9.9% of the outstanding Parent Shares such that, immediately following such Transfer, the Shareholder owns 9.9% of the outstanding Parent Shares.

5.Fiduciary Duties. This Agreement is being entered into by the Shareholder solely as a record and/or beneficial owner of the Subject Shares. Nothing in this Agreement shall restrict or limit the ability of the Shareholder or any of its Affiliates who is a director, officer or employee of Parent to take any action in his or her capacity as a director, officer or employee of Parent, including the exercise of fiduciary duties to Parent or its shareholders.

6.No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in the Company any direct or indirect ownership or incidence of ownership of or with respect to the Subject Shares. All ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to the Shareholder. Except as otherwise provided herein, the Company shall have no authority to direct the Shareholder in the voting or disposition of any of the Subject Shares.

7.Regulatory Covenants. The Shareholder agrees to use reasonable best efforts to assist and cooperate with Parent, Merger Sub and the Company to obtain all necessary, proper or advisable actions or nonactions, consents, approvals, authorizations, waivers and qualifications from any Governmental Authority whose consent is required in connection with the proposed amendment of the Investment Management Agreement between Third Point LLC and Third Point Enhanced LP, dated July 31, 2018 (the “Investment Management Agreement”), and as amended and restated on February 28, 2019; provided that the Shareholder shall in no event be required to take (or not take) any actions pursuant to this Section 7 if such action or nonaction would adversely affect the Shareholder or its Affiliates (other than in respect of the Investment Management Agreement and the Third Amended and Restated Exempted Limited Partnership Agreement of Third Point Enhanced LP, by and among Third Point Advisors LLC, Third Point Reinsurance Company Ltd. and Third Point Reinsurance (USA) Ltd., and Parent, dated as of August 6, 2020, to which reasonable best efforts shall apply).

8.Additional Covenants.

(a)Further Assurances. From time to time and without additional consideration, the Shareholder shall (at its sole cost and expense) execute and deliver, or cause to be executed and delivered, such additional instruments, and shall (at its sole cost and expense) take such further actions, as the Company may reasonably request for the purpose of carrying out and furthering the intent of this Agreement and the transactions contemplated by the Merger Agreement.

(b)No Legal Action. The Shareholder shall not, and shall cause its Representatives not to, bring, commence, institute, maintain, prosecute or voluntarily aid any claim, appeal, or proceeding which (i) challenges the validity of or seeks to enjoin the

(c)Stock Dividends, etc. In the event of a stock split, stock dividend or distribution, or any change in the Parent Shares by reason of any split-up, subdivision, reverse stock split, consolidation, recapitalization, combination, reclassification, reincorporation, exchange of shares or the like, the terms “Parent Shares” and “Subject Shares” shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may be changed or exchanged or which are received in such transaction.
