FOUNDERS AGREEMENT

THIS FOUNDERS AGREEMENT (this “Agreement”) dated as of December 22, 2011, is by and among Third Point Reinsurance Company Ltd., a Bermuda Class 4 insurance company (the “Company” and together with any Participant who joins this Agreement as a “Payor”, the “Payors” and each, a “Payor”), KEP TP Bermuda Ltd. and KIA TP Bermuda Ltd. (collectively, “Kelso Bermuda”), Pine Brook LVR, L.P. (“Pine Brook”), P RE Opportunities Ltd. (“PROL”), Dowling Capital Partners I, L.P. (“Dowling” and together with Kelso Bermuda, Pine Brook and PROL the “Founders” and together with the Company, the “Parties”). Capitalized terms used and not defined herein shall have the meaning given to such terms in the joint venture and investment management agreement dated the date hereof by and among the Company, Holdco, Third Point LLC and Third Point Advisors LLC (the “JV/IMA”).

WHEREAS, in connection with certain investments in the Company made directly or indirectly by KEP TP Holdings, L.P. and KIA TP Holdings, L.P. (collectively, “Kelso”), Pine Brook, PROL and Dowling the Payor desires to make or cause to be made a monthly payment to the Founders; and

WHEREAS, the parties wish to specify in this Agreement the terms of the monthly amounts payable by the Payor to the Founders.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises herein contained and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Founders’ Payment.

(a) Each of Kelso, Pine Brook, PROL and Dowling has made an investment in the Company as of the date hereof.

(b) In consideration for the investments described in Section 1(a) above, as of the first day of each month following the date hereof and until December 31, 2016, the Payor will pay to each Founder, in cash, such Founder’s Individual Founders Payment (together with any amount of such Individual Founders Payment previously accrued and not yet paid), provided that a Founder will not be entitled to the payment of its Individual Founders Payment following an IRR Satisfaction Event with respect to such Founder (or, in the case of Kelso Bermuda, Kelso). For the avoidance of doubt, following an IRR Satisfaction Event with respect to a Founder (or, in the case of Kelso Bermuda, Kelso), the Payor’s obligation to pay such Founder its Individual Founders Payment expires and such Founder’s Individual Founders Payment will not be allocated to the other Founders. Such forfeited Individual Founders Payments are referred to herein as “Forfeited Founders Payments”.

(c) All applicable Participant Payments accrue from the beginning of each month (or from the Commencement Date in the case of the first month or partial month following an initial capital contribution by a Participant (other than TP GP)) with respect to each Participant, based on the Capital Account balance of each such Participant (other than TP GP) as of the beginning of such month (or on the Commencement Date with respect to such Participant (other than TP GP) in the case of any such first month or partial month following an initial capital contribution). For the avoidance of doubt, each Founder will refund to the Payor the unearned portion of the Individual Founders Payment if a withdrawal is made by a Participant prior to the end of the month. All payments of the Individual Founders Payments to the Founders under this Agreement shall be made without any reduction, deduction or withholding for or on account of any tax (including without limitation, any value added tax), unless required by Law.

2. Transfers to Affiliates. In the event Pine Brook transfers any of its Shares to one of its Affiliates (the “Selling Founder” and such affiliate transferee, an “Affiliate Transferee”), then, for purposes of this Agreement and the Structuring Agreement, (i) such Affiliate Transferee shall be deemed to have been a party to this Agreement as a “Founder” as of the date hereof and shall execute a joinder to this Agreement in a form acceptable to the Company, (ii) such Affiliate Transferee will be allocated an Individual Percentage equal to such Affiliate Transferee’s Pro-Rata Portion and the Individual Percentage of the Selling Founder will be reduced by an amount equal to the Affiliate Transferee’s Pro-Rata Portion and Annex A automatically will be deemed to be amended to give effect to the foregoing (iii) such Affiliate Transferee will be deemed to have paid to the Payor a consideration for its Shares equal to the product of (a) the aggregate consideration paid by the Selling Founder to the Company and (b) the Affiliate Transferee’s Pro-Rata portion; and the consideration paid by the Selling Founder to the Company will be deemed to be reduced by the amount of the consideration allocated to the Affiliate Transferee; (iv) such Affiliate Transferee will be deemed to have received from the Payor an amount of distributions equal to the product of (a) the aggregate distributions received by the Selling Founder from the Payor and (b) the Affiliate Transferee’s Pro-Rata portion; and the distributions received by the Selling Founder from the Payor will be deemed to be reduced by the amount of the distributions allocated to the Affiliate Transferee and (v) such Affiliate Transferee will be deemed to have received (or be entitled to, in the case of Founders Payments accrued and not yet paid) a Founders Payment equal to the product of (a) the amount of Founders Payment paid to (or accrued for the benefit of and not yet paid to) the Selling Founder and (b) the Affiliate Transferee’s Pro-Rata Portion; and the Founders Payment received by (or accrued for the benefit of and not yet paid to) the Selling Founder will be deemed to be reduced by the amount of the Founders Payment allocated to the Affiliate Transferee. The provisions of this Section 2 will apply to subsequent transfers of Shares from an Affiliate Transferee to another Affiliate Transferee as though the initial Affiliate Transferee is the “Selling Founder” and the subsequent Affiliate Transferee is the “Affiliate Transferee”.

3. Covenant of the Founders. In the event that Third Point LLC or any of its Affiliates is no longer acting as the investment manager pursuant to the JV/IMA and to the extent the Founders (including in the case of Kelso Bermuda, Kelso) enter into any arrangement with any New Investment Manager to otherwise share in the economic benefits afforded to such New Investment Manager, then for so long as Daniel S. Loeb holds any Shares, Daniel S. Loeb shall have the right to participate with the Founders (including in the case of Kelso Bermuda, Kelso) in any such arrangement pro-rata based on the number of Shares held by Daniel S. Loeb and the Founders (including in the case of Kelso Bermuda, Kelso) at the time of the Closing.
