In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to the Applicable Issuing Party (1) the Letter of Credit to be amended; (2) the proposed date of amendment thereof (which shall be a Business Day); (3) the nature of the proposed amendment; and (4) such other matters as the Applicable Issuing Party may require.

Unless the Applicable Issuing Party has received written notice from any Lender, the Administrative Agent or a Borrower, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in Article IV shall not then be satisfied (such conditions, for the avoidance of doubt, being inapplicable to any such amendment that does not constitute an L/C Credit Extension), then, subject to the terms and conditions hereof, the Applicable Issuing Party shall, on the requested date, issue a Letter of Credit for the account of such L/C Applicant or enter into the applicable amendment, as the case may be, in each case in accordance with the Applicable Issuing Party's usual and customary business practices. The Applicable Issuing Party will promptly notify the Administrative Agent of any L/C Credit Extension, and any decrease in the stated amount of or termination of a Letter of Credit prior to its stated expiry date. Immediately upon the issuance of each Fronted Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, without recourse or warranty, purchase from the Fronting Bank a risk participation in such Fronted Letter of

Credit in an amount equal to the product of such Lender's Applicable Percentage times the amount of such Fronted Letter of Credit.

(b) The L/C Administrator is hereby authorized to execute and deliver each Several Letter of Credit and each amendment to a Several Letter of Credit on behalf of each Lender (unless such Lender has advised the L/C Administrator that it is a Participating Bank) provided that, upon request of an L/C Applicant, such Several Letter of Credit or amendment will be executed by each Lender (other than a Participating Bank). The L/C Administrator shall use the Applicable Percentage of each Lender as its “Commitment share” under each Several Letter of Credit provided that the Participating Bank Issuer shall be severally (and not jointly) liable for an amount equal to its Applicable Percentage plus the Applicable Percentage of its Participating Bank under any such Several Letter of Credit. The L/C Administrator shall not amend any Several Letter of Credit to change the “Commitment shares” of an L/C Issuer or add or delete an L/C Issuer liable thereunder unless such amendment is done in connection with an assignment in accordance with Section 11.06, a change in the Lenders and/or the Applicable Percentages as a result of any increase in the Aggregate Commitments pursuant to Section 2.13 or any other addition or replacement of a Lender in accordance with the terms of this Agreement or a change in status of a Lender as a Participating Bank or Defaulting Lender. Fees owed by any Participating Bank to its Participating Bank Issuer pursuant to Section 2.03(j) shall accrue for the account of such Participating Bank only during such period as such Lender is a Participating Bank with respect to any such Several Letter of Credit. Each Lender hereby irrevocably constitutes and appoints the L/C Administrator its true and lawful attorney-in-fact for and on behalf of such Lender with full power of substitution and revocation in its own name or in the name of the L/C Administrator to issue, execute and deliver, as the case may be, each Several Letter of Credit and each amendment to a Several Letter of Credit and to carry out the purposes of this Agreement with respect to Several Letters of Credit. Upon request, each Lender shall execute such powers of attorney or other document as any beneficiary of any Several Letter of Credit may reasonably request to evidence the authority of the L/C Administrator to execute and deliver such Several Letter of Credit and any amendment or other modification thereto on behalf of the Lenders. Immediately upon issuance of each Several Letter of Credit, each Participating Bank shall be deemed to, and hereby irrevocably and unconditionally agrees to, without recourse or warranty, purchase from its Participating Bank Issuer a risk participation in such Several Letter of Credit in an amount equal to the product of such Participating Bank's Applicable Percentage times the amount of such Several Letter of Credit.

(A)subject to Section 2.03(b)(v), the expiry date of such requested Letter of Credit would occur more than twelve months after the date of issuance or last extension (or in the case of Letters of Credit denominated in Canadian Dollars, thirteen months solely if necessary for regulatory purposes) unless the Lenders have approved such expiry date;

(B)the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless all the Lenders have approved such expiry date;

(D) if the Letter of Credit is a Several Letter of Credit, a Participating Bank does not have a Participating Bank Issuer for such Letter of Credit.

(ii) An L/C Issuer shall not be under any obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such L/C Issuer from issuing such Letter of Credit, or any Law applicable to such L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such L/C Issuer shall prohibit, or request that such L/C Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such L/C Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such L/C Issuer is not otherwise compensated hereunder) not in effect on the Effective Date, or shall impose upon such L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Effective Date and which such L/C Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it;

(B) except as otherwise agreed by the Administrative Agent and the Applicable Issuing Party, such Letter of Credit is in an initial stated amount less than $50,000;

(C) such Letter of Credit is to be denominated in a currency other than Dollars or an Alternative Currency or, after giving effect to such issuance the Dollar Equivalent of the stated amount of all Letters of Credit denominated in an Alternative Currency would exceed the Alternative Currency L/C Sublimit;

(D) such Letter of Credit is not substantially in the form of Exhibit B-1 or B-2, as applicable; provided that the Applicable Issuing Party can and will agree to reasonable changes to such forms, not adverse to interests of the Lenders, necessary to satisfy any then applicable requirements of the applicable insurance regulators and/or of any rating agency; or

(E) if the Letter of Credit is a Fronted Letter of Credit, a default of any Lender's obligations to fund under Section 2.03(c) exists or any Lender is at such time a Defaulting Lender hereunder, unless the Fronting Bank has entered into satisfactory arrangements to eliminate the Fronting Bank's risk with respect to such Lender.

(iii) The Applicable Issuing Party shall not amend any Letter of Credit if (A) the Applicable Issuing Party would not be permitted at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit.

(iv) The L/C Administrator shall act on behalf of the Lenders with respect to any Several Letters of Credit issued hereunder and the documents associated thereto and the Fronting Bank shall act on behalf of the Lenders with respect to any Fronted Letters of Credit issued by the Fronting Bank hereunder and the documents associated therewith, and each of the L/C Administrator and the Fronting Bank shall have all of the benefits and immunities (A) provided to the Administrative Agent in Article IX with respect to any acts taken or omissions suffered by the L/C Administrator or the Fronting Bank, as the case may be, in connection with Letters of Credit issued or proposed to be issued hereunder and Issuer Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article IX included the L/C Administrator and the Fronting Bank with respect to such acts or omissions, and (B) as additionally provided herein with respect to the L/C Administrator and the Fronting Bank.

(v) If an L/C Applicant so requests in any applicable Letter of Credit Application, the Applicable Issuing Party may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the Applicable Issuing Party to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the Applicable Issuing Party, the applicable L/C Applicant shall not be required to make a specific request to the Applicable Issuing Party for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the Applicable Issuing Party to permit the extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date; provided, that the Applicable Issuing Party shall not permit any such extension if (A) the Applicable Issuing Party has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (i) or (ii) of Section 2.03(b) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the Non-Extension Notice Date (1) from the applicable L/C Applicant that it does not wish to have such Letter of Credit extended, (2) from the Administrative Agent that the Lenders have elected not to permit such extension or (3) from the Administrative Agent, any Lender or any Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied, and in each such case directing the Applicable Issuing Party not to permit such extension.

(c)	Drawings and Reimbursements; Funding of Participations.

(i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit (a “Drawing Request”), the Applicable Issuing Party shall notify the applicable L/C Applicant and the Administrative Agent of the receipt of such Drawing Request and of the date the Applicable Issuing Party will honor such request (each such date, an “Honor Date”). Not later than 11:00 a.m. on such Honor Date in the case of Letters of Credit to be reimbursed in Dollars or the Applicable Time on the Honor Date with respect to Letters of Credit to be reimbursed in an Alternative Currency, the applicable L/C Applicant shall reimburse the respective L/C Issuers through the Administrative Agent in Same Day Funds the amount of the Drawing Request. In the case of a Letter of Credit denominated in an Alternative Currency, the applicable L/C Applicant shall reimburse the Fronting Bank through the Administrative Agent in such Alternative Currency, unless (A) the Fronting Bank (at its option) shall have specified in such notice that it will require reimbursement in Dollars, or (B) in the absence of any such requirement for reimbursement in Dollars, such L/C Applicant shall have notified the Fronting Bank promptly following receipt of notice of drawing that such L/C Applicant will reimburse the Fronting Bank in Dollars. In the case of any such reimbursement in Dollars of a drawing under a Letter of Credit denominated in an Alternative Currency, the Administrative Agent shall notify the applicable L/C Applicant of the Dollar Equivalent of the amount of the drawing promptly following the determination thereof. To the extent that Same Day Funds are received by the Administrative Agent from the applicable L/C Applicant prior to 11:00 a.m. (or the Applicable Time in the case of any Letter of Credit to be reimbursed in an Alternative Currency) on the Honor Date, the Administrative Agent shall remit the funds so received to the Applicable Issuing Party. Any notice given by the Applicable Issuing Party or the Administrative Agent pursuant to this Section 2.03(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) With respect to any Drawing Request, if Same Day Funds are not received by the Administrative Agent from the applicable L/C Applicant prior to 11:00 a.m. (or the Applicable Time in the case of any Letter of Credit to be reimbursed in an Alternative Currency) on the Honor Date in the amount of such Drawing Request, the Administrative Agent shall promptly notify each Lender of such Drawing Request, the amount of the unreimbursed drawing (the “Unreimbursed Amount”) and such Lender's Applicable Percentage of such Unreimbursed Amount. If such Unreimbursed Amount relates to a Letter of Credit issued in an Alternative Currency, such Unreimbursed Amount shall be the Dollar Equivalent (as calculated by the Administrative Agent using the Spot Rate) of the Drawing Request. Each Lender shall make funds available to the Administrative Agent for the account of the Applicable Issuing Party at the Administrative Agent's Office in an amount equal to its Applicable Percentage of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent (the “L/C Advance Date”). The Administrative Agent shall remit the funds so received to the Applicable Issuing Party. To the extent that Same Day Funds are received by the Administrative Agent from the Lenders (or the Participating Bank Issuer on behalf of a Participating Bank) with respect to a Several Letter of Credit prior to 2:00 p.m. on

the L/C Advance Date, the Administrative Agent shall notify the L/C Administrator and the L/C Administrator shall promptly make such funds available to the beneficiary of such Several Letter of Credit on such date. To the extent that the L/C Administrator has not delivered funds to any beneficiary of a Several Letter of Credit on behalf of a Lender on the L/C Advance Date, if Same Day Funds are received by the Administrative Agent from such Lender: (i) after 2:00 p.m. on the L/C Advance Date, the L/C Administrator shall make such funds available to such beneficiary on the next Business Day; (ii) prior to 2:00 p.m. on any Business Day after the L/C Advance Date, the L/C Administrator shall make those funds available to such beneficiary on such Business Day; and (iii) after 2:00 p.m. on any Business Day after the L/C Advance Date, the L/C Administrator shall make those funds available to such beneficiary on the next Business Day following such Business Day.

(iii) Unless the Administrative Agent or L/C Administrator receives notice from a Lender prior to any L/C Advance Date with respect to a Several Letter of Credit that such Lender will not make available as and when required hereunder to the Administrative Agent the amount of such Lender's L/C Advance on such L/C Advance Date, the Administrative Agent and the L/C Administrator may assume that such Lender has made such amount available to the Administrative Agent in Same Day Funds on the L/C Advance Date and the L/C Administrator may (but shall not be required), in reliance upon such assumption, make available to the beneficiary of the related Several Letter of Credit on such date such Lender's L/C Advance.

(iv) With respect to any Unreimbursed Amount, the applicable L/C Applicant shall be deemed to have incurred an L/C Advance in the Dollar Equivalent of the Unreimbursed Amount from (x) in the case of Fronted Letters of Credit, the Fronting Bank and (y) in the case of Several Letters of Credit, from the Lenders to the extent that they have provided funds with respect to such Several Letter of Credit pursuant to Section 2.03(c)(ii), from the Participating Bank Issuer or from the L/C Administrator to the extent it has made funds available on behalf of a Lender pursuant to Section 2.03(c)(iii). L/C Advances shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. Each Lender's or Participating Bank's payment to the Administrative Agent for the account of the Applicable Issuing Party pursuant to Section 2.03(c)(ii) shall be deemed payment in respect of its participation in such L/C Advance and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03. Any payment by an L/C Applicant in respect of such L/C Advance shall be made to the Administrative Agent and upon receipt applied by the Administrative Agent in accordance with Section 2.03(d).

(v) Until each Lender funds its L/C Advance pursuant to this Section 2.03(c) to reimburse the Applicable Issuing Party for any amount drawn under any Letter of Credit, interest in respect of such Lender's Applicable Percentage of such Unreimbursed Amount shall be solely for the account of the Fronting Bank or the L/C Administrator, as applicable.

(vi) Each Lender's obligation to make L/C Advances to reimburse the Applicable Issuing Party for amounts drawn under Letters of Credit, as contemplated by

this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Administrative Agent, the Applicable Issuing Party, any Lender, any L/C Applicant, any beneficiary named in any Letter of Credit, any transferee of any Letter of Credit (or any Persons for whom any such transferee may be acting) or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, (C) any lack of validity or enforceability of such Letter of Credit, this Agreement or any other Loan Document, (D) any draft, certificate or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect, (E) the surrender or impairment of any security for the performance or observance of any of the terms of the Loan Documents, (F) any matter or event set forth in Section 2.03(b)(i), or (G) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such making of an L/C Advance shall relieve or otherwise impair the obligation of the applicable L/C Applicant to reimburse the respective L/C Issuers for the amount of any payment made by the respective L/C Issuers under any Letter of Credit, together with interest as provided herein.

(vii) If any Lender fails to make available to the Administrative Agent for the account of the Applicable Issuing Party any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.03(c) by the time specified in the third sentence of Section 2.03(c)(ii), the Applicable Issuing Party, shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Applicable Issuing Party, as the case may be, at a rate per annum equal to the Federal Funds Rate, plus any administrative, processing or similar fees customarily charged by the Applicable Issuing Party in connection with the foregoing. A certificate of the Applicable Issuing Party, submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vii) shall be conclusive absent manifest error.

(d) Repayment of Participations.

(i) At any time after the Applicable Issuing Party has made a payment under any Letter of Credit and has received from any Lender such Lender's L/C Advance in respect of such payment in accordance with Section 2.03(c), if the Administrative Agent receives any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the applicable L/C Applicant or otherwise, including proceeds of Cash Collateral or other Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Applicable Percentage thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender's L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

(ii) If any payment received by the Administrative Agent pursuant to Section 2.03(c)(i) is required to be returned under any of the circumstances described in Section 11.05 (including pursuant to any settlement entered into by the Applicable Issuing Party

in its discretion), each Lender shall pay to the Administrative Agent for the account of the Applicable Issuing Party its Applicable Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Obligations Absolute. The obligation of each L/C Applicant to reimburse the respective L/C Issuers for each drawing under each Letter of Credit issued for the account of such L/C Applicant and to repay each related L/C Advance shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other Loan Document;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that any Borrower or any Subsidiary for whose account such Letter of Credit was issued may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the Applicable Issuing Party or any L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) any payment by the Applicable Issuing Party under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the Applicable Issuing Party under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law;

(v) waiver by the Applicable Issuing Party of any requirement that exists for the Applicable Issuing Party's protection and not the protection of the L/C Applicant;

(vi) any payment made by the L/C Issuer in respect of an otherwise complying item presented after the date specified as the expiration date of, or the date by which documents must be received under such Letter of Credit if presentation after such date is authorized by the UCC, the ISP or the UCP to the extent the UCC, the ISP or the UCP applies to such Letter of Credit by its terms;

(vii) any adverse change in the relevant exchange rates or in the availability of the relevant Alternative Currency to the applicable L/C Applicant or in the relevant currency markets generally; or

(viii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Borrower or any L/C Applicant.

Each L/C Applicant shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with such L/C Applicant’s instructions or other irregularity, such L/C Applicant will promptly notify the Applicable Issuing Party. Such L/C Applicant shall be conclusively deemed to have waived any such claim against the Applicable Issuing Party and its correspondents unless such notice is given as aforesaid.

(f) Role of Applicable Issuing Party. Each Lender and each L/C Applicant agrees that, in paying any drawing under a Letter of Credit, the Applicable Issuing Party shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the Applicable Issuing Parties, the L/C Issuers, the Lenders, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of an Applicable Issuing Party or L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Required Lenders; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. Each L/C Applicant hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, that this assumption is not intended to, and shall not, preclude such L/C Applicant from pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Applicable Issuing Parties, the L/C Issuers, the Lenders, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of an Applicable Issuing Party or L/C Issuer shall be liable or responsible for any of the matters described in clauses (i) through (viii) of Section 2.03(e); provided, that anything in such clauses to the contrary notwithstanding, the applicable L/C Applicant may have a claim against the Applicable Issuing Party and/or the L/C Issuers, and the Applicable Issuing Party and/or the L/C Issuers may be liable to such L/C Applicant to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by such L/C Applicant which such L/C Applicant proves were caused by the Applicable Issuing Party's or L/C Issuer's willful misconduct or gross negligence or the Applicable Issuing Party's or L/C Issuer's willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the Applicable Issuing Party may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and neither the Applicable Issuing Party nor any L/C Issuer shall be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or

assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason. The Applicable Issuing Party may send a Letter of Credit or conduct any communication to or from the beneficiary via the Society for Worldwide Interbank Financial Telecommunication (“SWIFT”) message or overnight courier, or any other commercially reasonable means of communicating with a beneficiary (unless such beneficiary or the L/C Applicant on behalf of such beneficiary has advised the Applicable Issuing Party of the preferred means of communication).

(g) Cash Collateral.

(i) If the Administrative Agent notifies Alterra Capital at any time that the Total Outstanding Amount of L/C Obligations with respect to Alternative Currency denominated Letters of Credit at such time exceeds 103% of the Alternative Currency L/C Sublimit, then, within two Business Days after receipt of such notice, the applicable Borrower(s) shall either Cash Collateralize the L/C Obligations of such Borrower(s) in an amount equal to such excess or post additional Eligible Collateral having an Adjusted Fair Market Value equal to such excess. Upon the request of the applicable Borrower(s) made within two Business Days following any Revaluation Date, the Administrative Agent will, so long as no Default then exists, release Cash Collateral to such Borrower(s) in an amount up to the excess of (x) the aggregate amount of Cash Collateral on deposit with respect to Alternative Currency denominated Letters of Credit over (y) 103% of the Alternative Currency L/C Sublimit.

(ii) The Administrative Agent or the Fronting Bank may, at any time and from time to time after the initial deposit of Cash Collateral pursuant to clause (i) above, request additional Cash Collateral to the extent the amount of Cash Collateral with respect to Alternative Currency denominated Letters of Credit is less than the positive difference between the Total Outstanding Amount of all L/C Obligations for Alternative Currency denominated Letters of Credit and 103% of the Alternative Currency L/C Sublimit due to exchange rate fluctuations.

(h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the Applicable Issuing Party and the applicable L/C Applicant when a Letter of Credit is issued either the rules of the ISP or the UCP at the option of such L/C Applicant shall apply to each Letter of Credit.

(i) Letter of Credit Fees. Each L/C Applicant shall pay to the Administrative Agent for the account of each Lender in accordance, subject to Section 2.17, with its Applicable Percentage in Dollars, a letter of credit fee (the “Letter of Credit Fee”) for each Letter of Credit issued for the account of such L/C Applicant equal to the Applicable Rate times the Dollar Equivalent of the daily amount available to be drawn under such Letter of Credit. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.08. Letter of Credit Fees shall be (i) computed on a quarterly basis in arrears and (ii) due and payable on the first Business Day after the end of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand; provided that with respect to the Existing Letters of

Credit and any Letters of Credit issued on or before December, 31, 2011, Letter of Credit fees for such Letters of Credit shall be payable on March 31, 2012 and such date thereafter . Notwithstanding anything to the contrary contained herein, upon the request of the Required Lenders, while any Event of Default exists, all Letter of Credit Fees shall accrue at the Default Rate.

(j) Fronting Fee and Documentary and Processing Charges.

(i) Each L/C Applicant shall pay directly to the Fronting Bank for its own account in Dollars a fronting fee with respect to each Fronted Letter of Credit issued for the account of such L/C Applicant by the Fronting Bank, at the rate per annum specified in the Bank of America Fee Letter, computed on the Dollar Equivalent of the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears. Such fronting fee shall be due and payable at such times (no more frequently than quarterly) as the Fronting Bank advises such L/C Applicant, on the Letter of Credit Expiration Date and thereafter on demand, it being understood that the Fronting Bank will invoice each L/C Applicant directly for amounts due under this Section 2.03(j). For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.08. In addition, each L/C Applicant shall pay directly to the Applicable Issuing Party for its own account letter of credit processing fees as set forth in the Bank of America Fee Letter. Such fees are due and payable on demand and are nonrefundable.

(ii) Each Participating Bank with respect to a Several Letter of Credit shall pay to its Participating Bank Issuer a fronting fee (the “Several L/C Fronting Fee”) computed on the risk participation purchased by such Participating Bank from such Participating Bank Issuer with respect to such Several Letter of Credit at the rate per annum and at the times and in the manner agreed upon by such Participating Bank and its Participating Bank Issuer.

(k) Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control.

(l) Existing Letters of Credit.

(i) On and after the Effective Date, the Existing Letters of Credit shall be deemed to be issued under this Agreement for all purposes, including for purposes of the fees to be collected pursuant to Sections 2.03(i) and (j), and reimbursement of costs and expenses to the extent provided herein and, in the case of Existing Letters of Credit issued for someone other than Alterra Bermuda, Alterra Bermuda shall be liable for such Existing Letters of Credit as if they had been issued for the account of Alterra Bermuda originally.

(ii) On the Effective Date, the risk participation of each Lender in the Existing Letters of Credit issued as Fronted Letters of Credit shall be equal to each Lender's Applicable Percentage and the risk participation of each Lender in the Existing Letters of

Credit issued as Several Letters of Credit (the “Existing Several Letters of Credit”) shall be equal to each Lender's Applicable Percentage.

(iii) Bank of America shall promptly amend each Existing Several Letter of Credit to reflect the applicable Lenders as L/C Issuers and the correct Applicable Percentages of such Lenders under such Existing Several Letter of Credit. The Borrowers shall cooperate with Bank of America and provide any necessary documents as may reasonably be requested by a beneficiary in connection with such amendment. From the Effective Date until the date on which an Existing Several Letter of Credit has been amended to reflect the applicable Lenders' Applicable Percentages, each Lender hereby irrevocably and unconditionally purchases from each lender who has issued such Existing Several Letter of Credit, a risk participation in such Existing Several Letter of Credit in an amount such that after giving effect to such purchase, each applicable Lender has its Applicable Percentage of such Existing Several Letter of Credit.

(iv) Prior to the date when all Existing Several Letters of Credit have been amended to delete any Person shown as a “Letter of Credit Bank” who is not a Lender hereunder (each such Person, a “Prior Lender”), the L/C Applicants of the Existing Several Letters of Credit and the Lenders agree that in the event of a draw under an Existing Several Letter of Credit for which funds have not been provided by the L/C Applicant or the Lenders in accordance with the terms hereof (such amount not so provided, the Prior Lender Liability”), the Administrative Agent shall withdraw Collateral from the Collateral Account of the L/C Applicant in an amount equal to the Prior Lender Liability and deliver such amount to the beneficiary of such Existing Several Letter of Credit. The amount withdrawn and paid to the beneficiary shall be deemed payment by such L/C Applicant with respect to the remaining Unreimbursed Amount with respect to such drawing. Any Lender whose failure to fund gave rise to such Prior Lender Liability shall be a Defaulting Lender.

2.04 Prepayments.

Each Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay its Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than 11:00 a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Applicable Percentage of such prepayment. If such notice is given by a Borrower, such Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein; provided, that any such notice may state that it is conditioned on the effectiveness of new credit facilities or other specified events in which case such notice may be revoked if such conditions are not satisfied and such prepayment will not be required but such

Borrower shall be obligated to pay amounts due pursuant to Section 3.05(b). Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05. Each such prepayment shall be applied to the Loans of the Lenders in accordance with their respective Applicable Percentages. In the event that any of the provisions of Sections 2.01 (A) through (D) have been violated and there are Loans outstanding, Alterra Capital shall cause the applicable Borrower(s) to prepay Loans in such amount as is necessary to cure such violation together with any additional amounts due pursuant to Section 3.05(b).

2.05 Termination or Reduction of Commitments. Alterra Capital may, upon notice to the Administrative Agent, terminate the Aggregate Commitments, or from time to time permanently reduce the Aggregate Commitments; provided that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m. three Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of $500,000 in excess thereof, and (iii) Alterra Capital shall not terminate or reduce the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Outstanding Amount would exceed the Aggregate Commitments: provided, that any such notice may state that it is conditioned on the effectiveness of new credit facilities or other specified events in which case such notice may be revoked if such conditions are not satisfied but such Borrower shall be obligated to pay amounts due pursuant to Section 3.05(b) to the extent that any concurrent prepayment of Eurodollar Loans would have been made in connection with such termination. The Administrative Agent will promptly notify the Lenders of any such notice of termination or reduction of the Aggregate Commitments. Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Lender according to its Applicable Percentage. All fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

2.06 Repayment of Loans. Each Borrower shall repay to the Lenders on the Maturity Date the aggregate principal amount of its respective Loans outstanding on such date.

2.07 Interest.

(a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate; and (ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate, if any.

(b) (i) If any amount of principal of any Loan or any L/C Advance is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(ii) If an Event of Default under Section 8.01(b) has occurred and is continuing, the overdue amount shall bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iii) Upon the request of the Required Lenders, while any Event of Default has occurred and is continuing (other than as set forth in clauses (b)(i) and (b)(ii) above), the Borrowers shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iv) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

2.08 Fees. In addition to certain fees described in subsections (g) and (h) of Section 2.03:

(a) Commitment Fee. Alterra Capital and Alterra Bermuda shall pay to the Administrative Agent for the account of each Lender in accordance with its Applicable Percentage, a commitment fee equal to 0.125% per annum times the Dollar Equivalent of the actual daily amount by which the Aggregate Commitments exceeds the Total Outstanding Amount. The commitment fee shall accrue at all times during the Availability Period, including at any time during which one or more of the conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the fiscal quarter ending on March 30, 2012), and on the Maturity Date. The commitment fee shall be calculated quarterly in arrears.

(b) Other Fees. (i) Alterra Capital and Alterra Bermuda shall pay to the Arrangers and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in the Fee Letters. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

(ii) Alterra Capital and Alterra Bermuda shall pay to the Lenders such upfront fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

2.09 Computation of Interest and Fees. All computations of interest for Base Rate Loans (including Base Rate Loans determined by reference to the Eurodollar Rate) shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Loan for the day on which the Loan is

made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall bear interest for one day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

2.10 Evidence of Debt.

(a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business in which it shall record the amount of each Loan made, the Type and the Interest Period thereof and the amount of repayments thereon. The accounts or records maintained by the Administrative Agent and each Lender shall be prima facie evidence of the amount of the Credit Extensions made by the Lenders to the Borrowers and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of a Borrower hereunder to pay any amount owing with respect to its Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the applicable Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such Lender's Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto.

(b) In addition to the accounts and records referred to in subsection (a) above, each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.11 Payments Generally; Administrative Agent’s Clawback.

(a) General. All payments to be made by the Borrowers shall be made free and clear of and without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrowers hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent's Office in Dollars and in Same Day Funds not later than 2:00 p.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Applicable Percentage (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender's Lending Office. All payments received by the Administrative Agent after 2:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment to be made by the Borrowers shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurodollar Rate Loans (or, in the case of any Borrowing of Base Rate Loans, prior to 12:00 noon on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of Base Rate Loans, that such Lender has made such share available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and applicable Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in Same Day Funds with interest thereon, for each day from and including the date such amount is made available to the applicable Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (B) in the case of a payment to be made by the applicable Borrower, the interest rate applicable to Base Rate Loans. If the applicable Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the applicable Borrower the amount of such interest paid by the applicable Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender's Loan included in such Borrowing. Any payment by the applicable Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(ii) Payments by Borrowers; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received written notice from the applicable Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders, the L/C Issuers or the Fronting Bank hereunder that the applicable Borrower will not make such payment, the Administrative Agent may assume that the applicable Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the applicable Person the amount due. In such event, if the applicable Borrower has not in fact made such payment, then each of the Lenders, the L/C Issuers and the Fronting Bank severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Person, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

A written notice of the Administrative Agent to any Lender or a Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

(c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the

foregoing provisions of this Article II, and such funds are not made available to the applicable Borrower by the Administrative Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall promptly return such funds (in like funds as received from such Lender) to such Lender, without interest.

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans, to fund Several Letters of Credit and purchase participations in Letters of Credit and to make payments pursuant to Section 11.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any Several Letter of Credit or any such participation or to make any payment under Section 11.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to fund a Several Letter of Credit, to purchase its participation or to make its payment under Section 11.04(c).

(e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan, any Letter of Credit or any L/C Advance in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan, any Letter of Credit or any L/C Advance in any particular place or manner.

2.12 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans or L/C Advances made by it or the participations in L/C Obligations resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Loans or L/C Advances or participations and accrued interest thereon greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and subparticipations in L/C Obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Total Outstanding Amount and other amounts owing them, provided, that:

(i) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(ii) the provisions of this Section shall not be construed to apply to (x) any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (y) the application of Cash Collateral provided for in Section 2.16(c), or (z) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or subparticipations in L/C Obligations to any assignee or participant, other than to Alterra Capital or any Subsidiary or Affiliate thereof (as to which the provisions of this Section shall apply).

Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

2.13 Increase in Commitments.

(a) Increase Request. Alterra Capital shall have the right at any time prior to the date that is 30 days prior to the Maturity Date to increase the aggregate Commitments hereunder by an amount (for all such requests) not exceeding $500,000,000 by adding to this Agreement one or more other Eligible Assignees (which may include any existing Lender, with the consent of such Lender in its sole discretion) (each such bank, a “Supplemental Lender”) with the approval of (x) the Administrative Agent (which approval shall not be unreasonably withheld or delayed); provided that no consent of the Administrative Agent will be required in the case of any such Eligible Assignee that is a Lender or an Affiliate of a Lender and (y) the Fronting Bank (which approval shall not be unreasonably withheld or delayed), provided that (i) each Supplemental Lender shall have entered into an agreement pursuant to which such Supplemental Lender shall undertake a Commitment (or, if such Supplemental Lender is an existing Lender, pursuant to which its Commitment shall be increased), (ii) such Commitment of any Supplemental Lender that is not an existing Lender shall be in an amount of at least $25,000,000, (iii) such Commitment (together with the increased Commitment(s) of all other Supplemental Lenders being provided at such time) shall be in an aggregate amount of at least $25,000,000, and (iv) if such Supplemental Lender will need to be a Participating Bank, it has a Participating Bank Issuer.

(b) Required Supplemental Lender Documentation. Each such Supplemental Lender shall enter into an agreement in form and substance satisfactory to Alterra Capital and the Administrative Agent pursuant to which such Supplemental Lender shall, as of the effective date of such increase in the Commitments (which shall be a Business Day and, unless the Administrative Agent otherwise agrees, on which no issuance, amendment, renewal or extension of any Letter of Credit is scheduled to occur or no Borrowing is scheduled to be made, each a “Supplemental Commitment Date”), undertake a Commitment (or, if any such Supplemental Lender is an existing Lender, its Commitment shall be in addition to such Lender's Commitment hereunder on such date) and such Supplemental Lender shall thereupon become (or continue to be) a “Lender” for all purposes hereof.

(c) Conditions to Effectiveness of Increase. Notwithstanding the foregoing, no increase in the aggregate Commitments hereunder pursuant to this Section shall be effective unless:

(i) Alterra Capital shall have given the Administrative Agent written notice of any such increase at least three Business Days prior to the applicable Supplemental Commitment Date;

(ii) no Default shall have occurred and be continuing on the applicable Supplemental Commitment Date;

(iii) Alterra Capital shall deliver to the Administrative Agent a certificate of each Borrower dated as of the Supplemental Commitment Date signed by a Responsible Officer of such Borrower (x) certifying and attaching the resolutions adopted by such Borrower approving or consenting to such increase, and (y) in the case of Alterra Capital, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article V and the other Loan Documents shall be true in all material respects on and as of the applicable Supplemental Commitment Date with the same force and effect as if made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and (B) no Default exists; and

(iv) on each Supplemental Commitment Date, the Administrative Agent shall reallocate any outstanding Loans so that, after giving effect thereto, the Loans are held ratably by the Lenders in accordance with their respective Commitments (after giving effect to such increase) and each Borrower shall (A) prepay the interest due on such Loans prior to such Supplemental Commitment Date and (B) pay to the Lenders the amounts, if any, payable under Section 3.05 as if such Loans had been prepaid it being understood that the Administrative Agent and Alterra Capital will cooperate, to the extent feasible to set the Supplemental Commitment Date on a date which minimizes or eliminates the obligation of the Borrowers to pay additional amounts under Section 3.05.

(d) Revised Percentages and Letter of Credit Amendments. The Administrative Agent shall promptly notify the Lenders of the new Applicable Percentages after giving effect to the Supplemental Commitment. Promptly after the Supplemental Commitment Date, the L/C Administrator shall amend the outstanding Several Letters of Credit to reflect the new “Commitment share” of each Lender (including the Supplemental Lenders) and prior to the date a Several Letter of Credit has been amended to give effect to such new “Commitment share”, each Supplemental Lender shall be deemed to irrevocably and unconditionally purchase from each Lender who has issued such Several Letter of Credit, a risk participation in such Several Letter of Credit in an amount such that after giving effect to such purchase, each Lender (including the Supplemental Lender) has its Applicable Percentage of such Several Letter of Credit.

(e) Conflicting Provisions. This Section shall supersede any provisions in Section 2.12 or 11.01 to the contrary

2.14 Designated Borrower.

(a) Alterra Capital may designate any Wholly-Owned direct or indirect Subsidiary (an “Applicant Borrower”) as a Designated Borrower to request Letters of Credit and receive Loans hereunder by delivering to the Administrative Agent a duly executed Designated Borrower Request at least 15 Business Days (unless such Applicant Borrower is (i) organized in Bermuda, Ireland, the United Kingdom or the United States, in which case at least ten Business Days or (ii) Alterra Reinsurance USA, in which case at least five Business Days) prior to the proposed date specified in such Designated Borrower Request (the “Designated Date”) on which such Applicant Borrower is requested to become a Designated Borrower (or, in each case, such

shorter period as may be agreed by the Administrative Agent in its sole discretion). Promptly following its receipt of a Designated Borrower Request, the Administrative Agent shall deliver a copy thereof to each Lender and, if such Applicant Borrower is organized in a jurisdiction other than Bermuda, Ireland, the United Kingdom or the United States, such Lender shall, not later than the Designated Date specified therein, notify the Administrative Agent whether such Lender consents to such Applicant Borrower becoming a Designated Borrower. Each Lender agrees that it consents to the designation of any Applicant Borrower organized in Bermuda, Ireland, the United Kingdom or the United States as a Designated Borrower entitled to request Loans and Letters of Credit.

(b) Promptly following receipt of the necessary consents (if any) and satisfaction of the conditions set forth in Section 4.02(e), the Administrative Agent shall send a notice in substantially the form of Exhibit I (a “Designated Borrower Notice”) to Alterra Capital and the Lenders specifying the effective date upon which the applicable Applicant Borrower shall constitute a Designated Borrower for purposes hereof, whereupon each of the Lenders agrees to permit such Designated Borrower to request Letters of Credit and subject to receipt of consent from all the Lenders (if required under Section 2.14(a)), request Loans hereunder, on the terms and conditions set forth herein, and each of the parties agrees that such Designated Borrower otherwise shall be a Borrower for all purposes of this Agreement; provided that other than with regard to Alterra Reinsurance USA, no Loan Notice or Letter of Credit Application may be submitted by or on behalf of such Designated Borrower until the date five Business Days after the applicable Designated Date.

(c) If there are outstanding Letters of Credit which show the Designated Borrower as the account party, then on the applicable Designated Date, such Letters of Credit shall be deemed to be L/C Obligations of such Designated Borrower (and Alterra Bermuda shall cease to be liable for such Letters of Credit), such Designated Borrower shall execute such documents as may be reasonably requested by the Applicable Issuing Parties to reflect the same and such Designated Borrower shall comply with the provisions of Section 6.10 with respect to such Letters of Credit.

(d) Each Subsidiary that becomes a “Designated Borrower” pursuant to this Section 2.14 hereby irrevocably appoints Alterra Capital as its agent for all purposes relevant to this Agreement and each of the other Loan Documents, including (i) the giving and receipt of notices, (ii) the execution and delivery of all documents, instruments and certificates contemplated herein and all modifications hereto, and (iii) the receipt of the proceeds of any Loans, if any, made by the Lenders, to any such Designated Borrower hereunder. Any acknowledgment, consent, direction, certification or other action which might otherwise be valid or effective only if given or taken by all Borrowers, or by each Borrower acting singly, shall be valid and effective if given or taken only by Alterra Capital, whether or not any such other Borrower joins therein. Any notice, demand, consent, acknowledgement, direction, certification or other communication delivered to Alterra Capital in accordance with the terms of this Agreement shall be deemed to have been delivered to each Designated Borrower.

(e) Alterra Capital may from time to time, upon not less than 10 Business Days' notice from Alterra Capital to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), terminate a Designated Borrower's

status as such, provided that there are no outstanding Loans payable by or Letters of Credit issued for the account of such Designated Borrower, or other amounts payable by such Designated Borrower on account of any Loans or Letters of Credit made to it, as of the effective date of such termination. The Administrative Agent will promptly notify the Lenders of any such termination of a Designated Borrower's status.

2.15 Several Obligations of Borrowers. Except as otherwise expressly provided herein, the obligations of each Borrower shall be several in nature; it being understood that no Borrower that is an Insurance Subsidiary (other than Alterra Bermuda as expressly provided herein) shall be liable for the obligations of any other Borrower.

2.16 Cash Collateral.

(a) Certain Credit Support Events. If there shall exist a Defaulting Lender who has not provided Cash Collateral pursuant to Section 2.17(b) or whose L/C Obligations have not been reallocated pursuant to Section 2.17(a)(iv), each L/C Applicant shall be required to provide Cash Collateral in an amount sufficient to cover the Fronting Exposure with respect to such Defaulting Lender within five Business Days following the request of the Fronting Bank.

(b) Grant of Security Interest. Each L/C Applicant, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the Fronting Bank and the Lenders, and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as Cash Collateral pursuant to Sections 2.03(g), 2.16 or 8.02 or , and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.16(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent or the Fronting Bank as herein provided or Liens of the type described in Section 7.06(b) or Liens permitted under any control agreement with respect to such Cash Collateral, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the applicable Person providing such Cash Collateral will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America. The Person providing such Cash Collateral shall pay on demand therefor from time to time all customary account opening, activity and other administrative fees and charges in connection with the maintenance and disbursement of such Cash Collateral.

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of Sections 2.03, 2.17 or 8.02 in respect of Letters of Credit shall be held and applied to the satisfaction of the specific L/C Obligations, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or to secure other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 11.06(b)(vi)) or (ii) the determination by the Administrative Agent and the Fronting Bank that there exists excess Cash Collateral; provided, that the Person providing Cash Collateral and the Fronting Bank may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

2.17 Defaulting Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law:

(i) Waivers and Amendments. Such Defaulting Lender's right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of “Required Lenders” and Section 11.01.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender, whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise or received by the Administrative Agent from a Defaulting Lender pursuant to Section 11.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Fronting Bank hereunder; third, to Cash Collateralize the Fronting Bank's Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.16; fourth, as Alterra Capital may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and Alterra Capital, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender's potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the Fronting Bank's future Fronting Exposure and such Defaulting Lender's future L/C Obligations with respect to Several Letters of Credit with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.16; sixth, to the payment of any amounts owing to the Lenders or the Fronting Bank as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Fronting Bank against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the applicable Borrower as a result of any judgment of a court of competent jurisdiction obtained by the applicable Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and eighth, to such

Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Advances in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 4.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Obligations owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Obligations are held by the Lenders pro rata in accordance with the Commitments hereunder without giving effect to Section 2.17(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.17(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees.

(A) No Defaulting Lender shall be entitled to receive any fee payable under Section 2.08(a) for any period during which that Lender is a Defaulting Lender (and Alterra Capital and Alterra Bermuda shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender) except to the extent that it has provided Cash Collateral for its unfunded Commitment.

(B) Each Defaulting Lender shall be entitled to receive Letter of Credit Fees for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral.

(C) With respect to any Letter of Credit Fee not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such Letter of Credit fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender's participation in L/C Obligations that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to the Fronting Bank the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to the Fronting Bank's Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Applicable Percentages to Reduce Fronting Exposure. All or any part of such Defaulting Lender's participation in L/C Obligations shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to such Defaulting Lender's Commitment) but only to the extent that (x) the conditions set forth in Section 4.02(a) and (b) are satisfied at the time of such reallocation (and, unless Alterra Capital shall have otherwise notified the Administrative Agent at such time, the Borrowers shall be deemed to have represented and warranted that such conditions are satisfied at such

time), and (y) such reallocation does not cause the aggregate Total Outstanding Amount of any Non-Defaulting Lender to exceed such Non-Defaulting Lender's Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender's increased exposure following such reallocation.

(v) Cash Collateral. If the reallocation described in clause (a)(iv) above cannot, or can only partially, be effected, the applicable L/C Applicant shall, without prejudice to any right or remedy available to it hereunder or under applicable Law, Cash Collateralize the Fronting Bank's Fronting Exposure in accordance with the procedures set forth in Section 2.16 to the extent such Fronting Exposure has not been Cash Collateralized by the Defaulting Lender.

(b) Defaulting Lender Cure. If Alterra Capital, the Administrative Agent and the Fronting Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 2.17(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided, that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of a Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the Borrowers, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Payments Free of Taxes; Obligation to Withhold; Payments on Account of Taxes.

(i) Any and all payments by or on account of any obligation of the respective Borrower hereunder or under any other Loan Document shall be made without reduction or withholding for any Indemnified Taxes or Other Taxes except as required by applicable Laws. If any applicable Laws (as determined in the good faith discretion of the Administrative Agent) require the deduction or withholding of any Tax from any such payment by the Administrative Agent or a Borrower, then the Administrative Agent or such Borrower shall be entitled to make such deduction or withholding upon the basis of the information and documentation to be delivered pursuant to subsection (e) below.

(ii) If any Borrower or the Administrative Agent shall be required by the Code to withhold or deduct any Taxes, including both United States federal backup withholding and withholding taxes, from any payment, then (A) the Administrative Agent shall withhold or make such deductions as are determined by the Administrative Agent to be required based upon the information and documentation it has received pursuant to subsection (e) below, (B) the Administrative Agent shall timely pay the full amount withheld or deducted to the relevant Governmental Authority in accordance with the Code, and (C) to the extent that the withholding or deduction is made on account of Indemnified Taxes the sum payable by the applicable Borrower shall be increased as necessary so that after any required withholding or the making of all required deductions (including deductions applicable to additional sums payable under this Section 3.01) the applicable Recipient receives an amount equal to the sum it would have received had no such withholding or deduction been made.

(b) Payment of Other Taxes by the Borrowers. Without limiting the provisions of subsection (a) above, the respective Borrower shall timely pay any Other Taxes attributable to such Borrower's Obligations to the relevant Governmental Authority in accordance with applicable Law.

(c) Indemnification. (i) Each Borrower shall, and does hereby, severally, indemnify each Recipient, and shall make payment in respect thereof within 15 Business Days after receipt of written demand therefor made on such Borrower, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient with respect to such Borrower's Obligations and any penalties, interest and reasonable expenses arising therefrom or with respect thereto (provided that such penalties, interests and expenses are not attributable to the gross negligence, fraud or willful misconduct of the Person making such demand), whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability setting forth in reasonable detail the basis of such amount delivered to the applicable Borrower by a Lender or the Fronting Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, the Fronting Bank or the L/C Administrator, shall be conclusive absent manifest error. Each of the Borrowers shall also, and does hereby, severally (and not jointly) indemnify the Administrative Agent, and shall make payment in respect thereof within 10 days after demand therefor, for any amount with respect to such Borrower or its Obligations, other than amounts attributable to Excluded Taxes, which a Lender or the Fronting Bank for any reason fails to pay indefeasibly to the Administrative Agent as required pursuant to Section 3.01(c)(ii) below.

(ii) Each Lender and the Fronting Bank shall, and does hereby, severally indemnify the Administrative Agent, and shall make payment in respect thereof within 10 days after demand therefor, against (x) any Indemnified Taxes attributable to such Lender or the Fronting Bank (but only to the extent that the applicable Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrowers to do so), (y) any Taxes attributable to such Lender's failure to comply with the provisions of Section 11.06(c) relating to the maintenance of a

Participant Register and (z) any Excluded Taxes attributable to such Lender or the Fronting Bank, in each case, that are payable or paid by the Administrative Agent or a Borrower in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender and the Fronting Bank hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender or the Fronting Bank, as the case may be, under this Agreement or any other Loan Document against any amount due to the Administrative Agent under this clause (ii).

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower to a Governmental Authority with respect to such Borrower's Obligations, such Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Status of Lenders; Tax Documentation. Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to Alterra Capital and the Administrative Agent, at the time or times reasonably requested by Alterra Capital or the Administrative Agent, such properly completed and executed documentation reasonably requested by the applicable Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Alterra Capital or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by Alterra Capital or the Administrative Agent as will enable Alterra Capital or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.01(e)(i)(A) and (i)(B) below) shall not be required if in the Lender's reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(i) Without limiting the generality of the foregoing,

(A) any Lender that is a U.S. Person shall deliver to Alterra Capital and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Alterra Capital or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is entitled to do so under applicable Law, deliver to Alterra Capital and the Administrative Agent (in such

number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Alterra Capital or the Administrative Agent), whichever of the following is applicable:

(i) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii) executed originals of IRS Form W-8ECI;

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of Alterra Capital within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or

(iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Alterra Capital and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Alterra Capital or the Administrative Agent), executed originals of any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be

prescribed by applicable Law to permit Alterra Capital or the Administrative Agent to determine the withholding or deduction required to be made;

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to Alterra Capital and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by Alterra Capital or the Administrative Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by Alterra Capital or the Administrative Agent as may be necessary for Alterra Capital and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement; and

(E) if a Lender claims an exemption from withholding tax in a jurisdiction other than the United States, such Lender agrees with and in favor of the Administrative Agent, to deliver to the Administrative Agent any such form or forms, as may be required under the laws of such jurisdiction as a condition to exemption from, or reduction of, foreign withholding or backup withholding tax before receiving its first payment under this Agreement, but only if such Lender is legally able to deliver such forms, provided, that nothing in this Section 3.01(e)(i)(E) shall require a Lender to disclose any information that it deems to be confidential (including without limitation, its tax returns).

(ii) Each Lender agrees that if any form or certification it previously delivered pursuant to this Section 3.01 expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Alterra Capital and the Administrative Agent in writing of its legal inability to do so.

(f) Treatment of Certain Refunds. If the Administrative Agent, any Lender or the Fronting Bank determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified by a Borrower or with respect to which such Borrower has paid additional amounts pursuant to this Section, it shall pay to such Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 3.01 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (excluding Taxes) of the Administrative Agent, such Lender or the Fronting Bank, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund which shall not be subject to the limitations set forth in the immediately preceding parenthetical), provided that such Borrower, upon the request of the Administrative Agent, such Lender or the Fronting Bank, agrees to repay the amount paid over to such Borrower (plus any

penalties (other than any penalties attributable to gross negligence of or fraud or willful misconduct by such Administrative Agent, such Lender or the Fronting Bank as determined by a court of competent jurisdiction by a final and nonappealable judgment), interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or the Fronting Bank in the event the Administrative Agent, such Lender or the Fronting Bank is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this subsection, in no event will the applicable Recipient be required to pay any amount to any Borrower pursuant to this subsection the payment of which would place the Recipient in a less favorable net after-Tax position than such Recipient would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This subsection shall not be construed to require the Administrative Agent, any Lender or the Fronting Bank to make available its tax returns (or any other information relating to its taxes that it deems confidential) to such Borrower or any other Person.

(g) Survival. Each party's obligations under this Section 3.01 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender or the Fronting Bank, the termination of the Commitments and the repayment, satisfaction or discharge of all other Obligations.

3.02 Illegality. If any Lender determines that any Change in Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its Lending Office to make, maintain or fund Loans whose interest is determined by reference to the Eurodollar Rate, or to determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on written notice thereof by such Lender to the Borrowers through the Administrative Agent, (i) any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended, and (ii) if such notice asserts the illegality of such Lender making or maintaining Base Rate Loans the interest rate on which is determined by reference to the Eurodollar Rate component of the Base Rate, the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Eurodollar Rate component of the Base Rate, in each case until such Lender notifies the Administrative Agent and Alterra Capital that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (x) the Borrowers shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans (the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Eurodollar Rate component of the Base Rate), either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans and (y) if such notice asserts the illegality of such Lender determining or charging interest rates based upon the Eurodollar Rate, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender without reference to the Eurodollar Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the Eurodollar Rate.

Upon any such prepayment or conversion, the Borrowers shall also pay accrued interest on the amount so prepaid or converted.

3.03 Inability to Determine Rates. If the Required Lenders determine that for any reason in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan or in connection with an existing or proposed Base Rate Loan, or (c) the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will promptly so notify Alterra Capital and each Lender in writing. Thereafter, (x) the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended, and (y) in the event of a determination described in the preceding sentence with respect to the Eurodollar Rate component of the Base Rate, the utilization of the Eurodollar Rate component in determining the Base Rate shall be suspended, in each case until the Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the Borrowers may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement contemplated by Section 3.04(e)) or the Fronting Bank;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or the Fronting Bank or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Rate Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making converting to, continuing or maintaining any Eurodollar Rate Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the Fronting Bank of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the Fronting Bank hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or the Fronting Bank, the applicable Borrower

will pay to such Lender or the Fronting Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Fronting Bank, as the case may be, for such additional costs incurred or reduction suffered with respect to such Borrower’s Obligations.

(b) Capital Requirements. If any Lender or the Fronting Bank determines that any Change in Law affecting such Lender or the Fronting Bank or any Lending Office of such Lender or such Lender's or the Fronting Bank's holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender's or the Fronting Bank's capital or on the capital of such Lender's or the Fronting Bank's holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Fronting Bank or such Lender, to a level below that which such Lender or the Fronting Bank or such Lender's or the Fronting Bank's holding company could have achieved but for such Change in Law (taking into consideration such Lender's or the Fronting Bank's policies and the policies of such Lender's or the Fronting Bank's holding company with respect to capital adequacy), then from time to time the applicable Borrower will pay to such Lender or the Fronting Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Fronting Bank or such Lender's or the Fronting Bank's holding company for any such reduction suffered with respect to such Borrower's Obligations.

(c) Certificates for Reimbursement. A certificate of a Lender or the Fronting Bank setting forth in reasonable detail the amount or amounts (and the basis for such amount or amounts) necessary to compensate such Lender or the Fronting Bank or its holding company, as the case may be, as specified in Subsection (a) or (b) of this Section and delivered to Alterra Capital shall be conclusive absent manifest error so long as the determination of such amount or amounts is made by such Lender or the Fronting Bank in good faith and is applied to the Borrowers in a non-discriminatory manner as compared to similarly situated borrowers or similar credit facilities. Each Borrower shall pay such Lender or the Fronting Bank, as the case may be, the amount shown as due from such Borrower on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or the Fronting Bank to demand compensation pursuant to the foregoing provisions of this Section 3.04 shall not constitute a waiver of such Lender's or the Fronting Bank's right to demand such compensation, provided that the Borrowers shall not be required to compensate a Lender or the Fronting Bank pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than six months prior to the date that such Lender or the Fronting Bank, as the case may be, notifies Alterra Capital of the Change in Law giving rise to such increased costs or reductions and of such Lender's or the Fronting Bank's intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof).

(e) Reserves on Eurodollar Rate Loans. Each Borrower with respect to its Loans shall pay to each Lender, as long as such Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional interest on the unpaid principal

amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Loan, provided such Borrower shall have received at least 10 days' prior written notice (with a copy to the Administrative Agent) of such additional interest from such Lender. If a Lender fails to give written notice 10 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 10 days from receipt of such notice.

3.05 Compensation for Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, each Borrower with respect to its Loans shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

(b) any failure by such Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by such Borrower; or

(c) any assignment of a Eurodollar Rate Loan on a day other than the last day of the Interest Period therefor as a result of a request by Alterra Capital pursuant to Section 11.13 provided that this clause (c) shall not apply to any Defaulting Lender;

including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. Each Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by a Borrower to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

3.06 Mitigation Obligations; Replacement of Lenders or Fronting Bank.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or a Borrower is required to pay any indemnity or additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, or if any Lender gives a notice pursuant to Section 3.02, then at the request of Alterra Capital such Lender shall use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the good faith judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject such Lender to any

unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Alterra Capital hereby agrees to pay all reasonable out-of-pocket costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if a Borrower is required to pay any indemnity or additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 3.06(a), Alterra Capital may replace such Lender in accordance with Section 11.13.

(c) Replacement of Fronting Bank. If the Fronting Bank requests compensation under Section 3.04 or is entitled not to issue any Letter of Credit pursuant to Section 2.03(b)(ii) or if a Borrower is required to pay any indemnity or additional amount to the Fronting Bank or any Governmental Authority for the account of the Fronting Bank pursuant to Section 3.01, or the Fronting Bank ceases to be an NAIC Approved Bank, Alterra Capital may request that the Fronting Bank resign as the Fronting Bank hereunder and Alterra Capital may designate a new Lender as the Fronting Bank in accordance with Section 11.06(g).

3.07 Survival. All of the Borrowers’ obligations under this Article III shall survive termination of the Aggregate Commitments and repayment of all other Obligations hereunder.

ARTICLE IV.

6.09 Further Assurances. Promptly upon the request of the Administrative Agent, Alterra Capital shall cause each Borrower to execute, acknowledge, deliver and record and do any and all such further acts and deeds as the Administrative Agent may reasonably request from time to time in order to ensure that the Obligations of such Borrower are secured by a first

priority (subject only to Liens described in Sections 7.06(b) and (n)) perfected interest in the assets of such Borrower stated to be pledged pursuant to its Security Agreement and to perfect and maintain the validity, effectiveness and priority of its Security Agreement and the Liens intended to be created thereby.

At any time an Event of Default has occurred and is continuing, at the request of the Administrative Agent, Alterra Capital shall cause such Borrower to take such actions as may be necessary to ensure that its Collateral consists solely of Cash and Cash Equivalents; provided, that the concentration limits with regard to Cash Equivalents shall not apply.

(b) The minimum weighted average credit quality rating of the Eligible Collateral in each Collateral Account shall be at least AA/Aa2 or the equivalent; provided, that a Borrower shall not be in violation of this Section 6.10(b) if such violation occurs as a result of a change in the Fair Market Value or ratings of such Eligible Collateral (as opposed to a change in the makeup of such Eligible Collateral) unless such deficiency exists for 30 days.

ARTICLE IX.

ADMINISTRATIVE AGENT

9.01 Appointment and Authority. Each of the Lenders, each L/C Issuer, the L/C Administrator and the Fronting Bank hereby irrevocably appoints Bank of America to act on its behalf as the Administrative Agent hereunder (including the guaranty set forth in Article X) and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto except for Alterra Capital’s approval right set forth in Section 9.06 and Bank of America hereby accepts such appointment. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders, the L/C Issuers, the L/C Administrator and the Fronting Bank, and no Borrower shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

9.02 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Alterra Capital or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

9.03 Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be

expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable Law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Alterra Capital or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 11.01 and 8.02) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment.

The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by a Borrower, a Lender or the Fronting Bank.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

9.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Applicable Issuing Party, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Applicable Issuing Party unless the Administrative Agent shall have received notice to the contrary from such Lender or the Applicable Issuing Party prior to the making of such Loan or the issuance of such Letter of

Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

9.05 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub‑agents appointed by the Administrative Agent. The Administrative Agent and any such sub‑agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub‑agent and to the Related Parties of the Administrative Agent and any such sub‑agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and non appealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

9.06 Resignation of Administrative Agent. (A) The Administrative Agent may at any time give notice of its resignation to the Lenders, the Fronting Bank and Alterra Capital. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, with the prior written consent of Alterra Capital (except during the existence of an Event of Default), to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders, the L/C Issuers, the L/C Administrator and the Fronting Bank, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b) If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable Law, by notice in writing to Alterra Capital and such Person remove such Person as Administrative Agent and, with the prior written consent of Alterra Capital (except during the existence of an Event of Default), appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c) With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders, the L/C Issuers, the L/C Administrator or the Fronting Bank under any of the Loan Documents, the

retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) except for any indemnity payments or other amounts then owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender, the L/C Administrator and the Fronting Bank directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor's appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or removed) Administrative Agent (other than as provided in Section 3.01(g) and other than any rights to indemnity payments or other amounts owed to the retiring or removed Administrative Agent as of the Resignation Effective Date or the Removal Effective Date, as applicable), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided for above in this Section). The fees payable by Alterra Capital and Alterra Bermuda to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between Alterra Capital, Alterra Bermuda and such successor. After the retiring or removed Administrative Agent's resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 11.04 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent.

(d) Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also constitute its resignation as L/C Administrator and as the Fronting Bank provided, that prior to a termination of the Commitments that Bank of America may not resign as L/C Administrator and Fronting Bank unless either (x) there is another Fronting Bank under this Agreement and the Fronting Bank agrees to act as L/C Administrator hereunder or (y) the successor Administrative Agent or another Person who is an NAIC Approved Bank has agreed to assume the obligations of Bank of America as Fronting Bank and L/C Administrator hereunder. If Bank of America resigns as the Fronting Bank and L/C Administrator, it shall retain all the rights, powers, privileges and duties of the Fronting Bank and L/C Administrator hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as Fronting Bank and L/C Administrator and all L/C Obligations with respect thereto, including the right to require the Lenders to make L/C Advances with respect to Fronted Letters of Credit pursuant to Section 2.03(c). Upon the appointment of a successor Fronting Bank or L/C Administrator hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Fronting Bank or L/C Administrator, as applicable, (b) the retiring Fronting Bank or L/C Administrator shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents, and (c) the successor Fronting Bank or L/C Administrator shall issue letters of credit in substitution for (or amendments to) the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Fronting Bank or L/C Administrator, as the case may be, to effectively assume the obligations of the retiring Fronting Bank or L/C Administrator, as the case may be with respect to such Letters of Credit.

9.07 Non-Reliance on Administrative Agent and Other Lenders. Each Lender, the L/C Administrator and the Fronting Bank acknowledges that it has, independently and without reliance upon the Administrative Agent, the L/C Administrator, the Fronting Bank or any other Lender, or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender, the L/C Administrator and the Fronting Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent, the L/C Administrator, the Fronting Bank or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the Bookrunners, Arrangers, Syndication Agents, and Documentation Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender, the Fronting Bank or the L/C Administrator hereunder.

9.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Borrower, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on any Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the L/C Issuers, the L/C Administrator, the Fronting Bank and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuers, the L/C Administrator, the Fronting Bank and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuers, the L/C Administrator, the Fronting Bank and the Administrative Agent under Sections 2.03(i) and (j), 2.09 and 11.04) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender, each L/C Issuer, the L/C Administrator and the Fronting Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, the L/C Issuers, the L/C Administrator and the Fronting Bank, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.09 and 11.04.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender, any L/C Issuer, the L/C Administrator or the Fronting Bank any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender, any L/C Issuer, the L/C Administrator or the Fronting Bank or to authorize the Administrative Agent to vote in respect of the claim of any Lender any L/C Issuer, the L/C Administrator or the Fronting Bank in any such proceeding.

9.10 Collateral Matters. The Lenders and the Fronting Bank irrevocably authorize the Administrative Agent, at its option and in its discretion, to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (i) upon termination of the Aggregate Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit, (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted hereunder or under any other Loan Document, or (iii) upon approval of the requisite Lenders pursuant to Section 11.01(e); and (iv) as permitted under Sections 2.16, 2.17 and 6.10. Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release its interest in particular types or items of property, pursuant to this Section 9.10.

The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any Borrower in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders, the L/C Issuers, the L/C Administrator or the Fronting Bank for any failure to monitor or maintain any portion of the Collateral.

ARTICLE X.

ALTERRA CAPITAL GUARANTEE

10.01 Unconditional Guarantee. For valuable consideration, receipt whereof is hereby acknowledged, and to induce the Fronting Bank and each Lender to make Loans to and Issue Letters of Credit (or purchase participations therein) for the account of each Guaranteed Borrower and to induce the Administrative Agent to act hereunder, Alterra Capital hereby unconditionally and irrevocably guarantees to each Lender, the Fronting Bank and the Administrative Agent the punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all Obligations of the Guaranteed Borrowers, whether for principal, interest, fees, expenses, indemnification or otherwise, whether direct or indirect, absolute or contingent or now existing or hereafter arising (such Obligations being the “Guaranteed Obligations”). Without limiting the generality of the foregoing, Alterra Capital’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by each Guaranteed Borrower to the Administrative Agent, the Fronting Bank or any other Lender under this Agreement but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving any Guaranteed Borrower or its Affiliates. This is a guarantee of payment and not of collection merely.

10.02 Guarantee Absolute. Alterra Capital guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of this Agreement, regardless of any law or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Lender, the Fronting Bank or the Administrative Agent with respect thereto. The Obligations of Alterra Capital under this Article X are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against Alterra Capital to enforce this Article X, irrespective of whether any action is brought against any Guaranteed Borrower or whether any Guaranteed Borrower is joined in any such action or actions. The liability of Alterra Capital under this guarantee shall be irrevocable, absolute and unconditional irrespective of, and Alterra Capital hereby irrevocably waives any defense it may now or hereafter have in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of this Agreement, any other Loan Document or any other agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from this Agreement (other than this Article X);

(c) any taking, exchange, release or non-perfection of any collateral or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations;

(d) any change, restructuring or termination of the corporate structure or existence of any Guaranteed Borrower or any insolvency, bankruptcy, reorganization or other similar proceeding affecting any Guaranteed Borrower or any of its assets or any resulting release or discharge of any obligation of any Guaranteed Borrower under this Agreement; or

(e) any other circumstance (including, without limitation, any statute of limitations to the fullest extent permitted by applicable Law) which might otherwise constitute a defense available to, or a legal or equitable discharge of, Alterra Capital or any Guaranteed Borrower (other than a discharge arising from the payment in full of the Guaranteed Obligations).

This guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Lender, the Fronting Bank or the Administrative Agent upon the insolvency, bankruptcy or reorganization of Alterra Capital or otherwise, all as though such payment had not been made.

10.03 Waivers. Alterra Capital hereby expressly waives promptness, diligence, notice of acceptance, presentment, demand for payment, protest, any requirement that any right or power be exhausted or any action be taken against any of the Guaranteed Borrowers or against any other guarantor of all or any portion of the Guaranteed Obligations, and all other notices and demands whatsoever.

(a) Alterra Capital hereby waives any right to revoke this guaranty, and acknowledges that this guaranty is continuing in nature and applies to all Guaranteed

Obligations, whether existing now or in the future and regardless of whether Guaranteed Obligations are reduced to zero at any time or from time to time (other than a reduction to zero due to the payment in full in cash of the Guaranteed Obligations concurrently with or after the termination of all Commitments).

(b) Alterra Capital acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated herein and that the waivers set forth in this Article X are knowingly made in contemplation of such benefits.

10.04 Subrogation. Alterra Capital will not exercise any rights that it may now or hereafter acquire against any of the Guaranteed Borrowers or any other insider guarantor that arise from the existence, payment, performance or enforcement of the Guaranteed Obligations under this Agreement, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Administrative Agent, the Fronting Bank or any other Lender against any of the Guaranteed Borrowers or any other insider guarantor or any collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from any of the Guaranteed Borrowers or any other insider guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations shall have been paid in full in cash and the Commitments shall have terminated. If any amount shall be paid to Alterra Capital in violation of the preceding sentence at any time prior to the later of the payment in full in cash of the Guaranteed Obligations and the termination of the Commitments, such amount shall be held in trust for the benefit of the Administrative Agent, the Fronting Bank and the other Lenders and shall forthwith be paid to the Administrative Agent to be credited and applied to the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of this Agreement, or to be held as collateral for any Guaranteed Obligations thereafter arising.

10.05 Survival. This guaranty is a continuing guarantee and shall (a) remain in full force and effect until payment in full in cash of the Guaranteed Obligations and the termination of the Commitments and the expiration or cancellation of all Letters of Credit, (b) be binding upon Alterra Capital and its successors and assigns, (c) inure to the benefit of and be enforceable by each Lender (including each assignee Lender pursuant to Section 11.06), the Fronting Bank and the Administrative Agent and their respective successors, transferees and assigns and (d) shall be reinstated if at any time any payment to a Lender, the Fronting Bank or the Administrative Agent hereunder is required to be restored by such Lender, the Fronting Bank or the Administrative Agent. Without limiting the generality of the foregoing clause (c), any transferee of any interest in any Loan or Commitment of a Lender pursuant to Section 11.06 shall become vested with all the rights in respect thereof granted to such Lender herein or otherwise.

10.06 Severability. Notwithstanding any other provision of this Article X to the contrary, in the event that any action is brought seeking to invalidate Alterra Capital’s obligations under this Article X under any fraudulent conveyance or fraudulent transfer theory, Alterra Capital shall be liable under this Article X only for an amount equal to the maximum amount of liability that could have been incurred under applicable Law by Alterra Capital under

any guarantee of the Obligations of the Guaranteed Borrowers (or any portion thereof) at the time of the execution and delivery of this Agreement (or, if such date is determined not to be the appropriate date for determining the enforceability of Alterra Capital’s obligations under this Article X for fraudulent conveyance or transfer purposes, on the date determined to be so appropriate) without rendering such a hypothetical guarantee voidable under applicable Law relating to fraudulent conveyance or fraudulent transfer (the “Maximum Guaranteed Obligations”) and not for any greater amount, as if the stated amount of the Guaranteed Obligations had instead been the Maximum Guaranteed Obligations.

ARTICLE XI.

The obligations of the Lenders under this subsection (c) are subject to the provisions of Section 2.11(d).

11.05 Payments Set Aside. To the extent that any payment by or on behalf of a Borrower is made to the Administrative Agent, the Fronting Bank, the L/C Administrator or any Lender, or the Administrative Agent, the Fronting Bank, the L/C Administrator or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent, the Fronting Bank, the L/C Administrator or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender, the Fronting Bank and the L/C Administrator severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders, the Fronting Bank and the L/C Administrator under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

11.06 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors

102

and assigns permitted hereby, except that no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent, the Fronting Bank and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the L/C Administrator, the Fronting Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including for purposes of this subsection (b), direct obligations under and L/C Advances or participations in L/C Obligations) at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender's Commitment and/or the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender, no minimum amount need be assigned; and

(B) in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, Alterra Capital otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned;

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

103

(A) the consent of Alterra Capital (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender or an Affiliate of a Lender;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender or an Affiliate of such Lender; and

(C) the consent of the Fronting Bank shall be required for any assignment and, if such Assignee could not be an L/C Issuer of a Several Letter of Credit under applicable regulatory requirements, the Fronting Bank must have agreed (in its sole discretion) to front for such Assignee under Several Letters of Credit.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount of $3,500; provided, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire, and unless otherwise agreed between the assigning Lender and such Assignee, if any Several Letters of Credit are outstanding, all such outstanding Letters of Credit are either amended or replaced to give effect to such assignment on the Trade Date.

(v) No Assignment to Certain Persons. No such assignment shall be made (A) to Alterra Capital or any of Alterra Capital’s Subsidiaries or Affiliates, (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) to a natural Person.

(vi) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of Alterra Capital and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Fronting Bank or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans, obligations under Several Letters of Credit and participations in Fronted Letters of Credit in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become

104

effective under applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and 11.04 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by Alterra Capitals, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Upon request, each Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain at the Administrative Agent's Office a copy of each Assignment and Assumption and participation delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by each of the Borrowers, the Lenders, the L/C Administrator and the Fronting Bank at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to any Person (other than a natural person or Alterra Capital or any of Alterra Capital's Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender's rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender's participations in L/C Obligations and/or L/C Advances) owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers, the Administrative Agent, the Lenders and the Fronting Bank shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 11.04(d) with respect to any payments made by such Lender to its Participant(s).

105

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in Sections 11.01(b), (d), (e) and (h) that directly affects such Participant. Each Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section, (it being understood that the documentation required under Section 3.01(e) shall be delivered to the Lender who sells the participation) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided, that such Participant (A) agrees to be subject to the provisions of Sections 3.06 and 11.13 as if it were an assignee under paragraph (b) of this Section and (B) shall not be entitled to receive any greater payment under Sections 3.01 or 3.04, with respect to any participation, than the Lender from whom it acquired the applicable participation would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at Alterra Capital’s request and expense, to use reasonable efforts to cooperate with Alterra Capital to effectuate the provisions of Section 3.06 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.08 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.13 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of Alterra Capital, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with Alterra Capital's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless Alterra Capital is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Sections 3.01(e) and Section 3.06 as though it were a Lender.

106

(f) Certain Pledges. Any Lender may at any time pledge, assign or grant a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge, assignment or grant of a security interest to secure obligations to a Federal Reserve Bank or any central bank having jurisdiction over such Lender; provided that no such pledge, assignment or grant of a security interest shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee or grantee for such Lender as a party hereto.

(g) Resignation as L/C Administrator or Fronting Bank After Assignment or Request. Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Commitment and Loans pursuant to subsection (b) above, Bank of America may, upon 30 days' notice to Alterra Capital and the Lenders, resign as L/C Administrator and/or Fronting Bank. In the event of any such resignation as L/C Administrator and/or Fronting Bank, Alterra Capital shall be entitled to appoint from among the Lenders a successor L/C Administrator and/or Fronting Bank hereunder; provided, that prior to a termination of the Commitments that Bank of America may not resign as L/C Administrator and Fronting Bank unless either (x) there is another Fronting Bank under this Agreement and the Fronting Bank agrees to act as L/C Administrator hereunder or (y) the successor Administrative Agent or another Person who is an NAIC Approved Bank has agreed to assume the obligations of Bank of America as Fronting Bank and L/C Administrator hereunder. If Bank of America resigns as Fronting Bank and L/C Administrator, it shall retain all the rights, powers, privileges and duties of the Fronting Bank and L/C Administrator hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as Fronting Bank and L/C Administrator and all L/C Obligations with respect thereto (including the right to require the Lenders to make L/C Advances pursuant to Section 2.03(c)). Upon the appointment of a successor Fronting Bank and L/C Administrator, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Fronting Bank and L/C Administrator, and (b) the successor Fronting Bank and L/C Administrator shall issue letters of credit in substitution for (or amendments of) the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

11.07 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Lenders, the Fronting Bank and the L/C Administrator agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the NAIC), (c) to the extent required by applicable Laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement or any Eligible Assignee invited to be a Lender pursuant to Section 2.16(c) or (ii) any

107

actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to a Borrower and its obligations, this Agreement or payments hereunder, (g) on a confidential basis to (i) any rating agency in connection with rating Alterra Capital or its Subsidiaries or the credit facilities provided hereunder or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the credit facilities provided hereunder, (h) with the consent of Alterra Capital or (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent, any Lender, the Fronting Bank or any of their respective Affiliates on a nonconfidential basis from a source other than a Borrower (unless the receiving Person knows that such source is breaching a confidentiality agreement or any confidentiality obligation with any Borrower).

For purposes of this Section, “Information” means all information received from Alterra Capital or any Subsidiary relating to Alterra Capital or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the Fronting Bank on a nonconfidential basis prior to disclosure by Alterra Capital or any Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. Each Lender shall be responsible for a any breach of this confidentiality undertaking by any of its Related Parties.

Each of the Administrative Agent, the Lenders, the L/C Administrator and the Fronting Bank acknowledges that (a) the Information may include material non-public information concerning Alterra Capital or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use of material non-public information and (c) it will handle such material non-public information in accordance with applicable Law, including United States Federal and state securities Laws.

11.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender, the Fronting Bank, the L/C Administrator and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the Fronting Bank, the L/C Administrator or any such Affiliate to or for the credit or the account of any Borrower against any and all of the Obligations of such Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender, the Fronting Bank or the L/C Administrator, irrespective of whether or not such Lender, the Fronting Bank or the L/C Administrator shall have made any demand under this Agreement or any other Loan Document and although such obligations of such Borrower may be contingent or unmatured or are owed to a branch or office of such Lender, the Fronting Bank or the L/C Administrator different from the branch or office holding such deposit or obligated on such indebtedness; provided, that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.17 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in

108

trust for the benefit of the Administrative Agent, the Fronting Bank and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender, the L/C Administrator, the Fronting Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Administrator, the Fronting Bank or their respective Affiliates may have. Each Lender, the L/C Administrator and the Fronting Bank agrees to notify the applicable Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

11.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the applicable Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

11.10 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic imaging means (e.g. “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement.

11.11 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof it being understood that such representation and warranties shall only be made when made or deemed made hereunder. Such representations and warranties have been or will be relied upon by the Administrative Agent, the Fronting Bank and each Lender, regardless of any investigation made by the Administrative Agent, the Fronting Bank or any Lender or on their behalf and notwithstanding that the Administrative Agent, the Fronting Bank or any Lender may have had notice or knowledge of any Default at the time of any Credit

109

Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

11.12 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 11.12, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent or the Fronting Bank, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

11.13 Replacement of Lenders. If Alterra Capital is entitled to replace a Lender pursuant to the provisions of Section 3.06, or if any Lender is a Defaulting Lender or a Non-Consenting Lender or if any Lender ceases to be a NAIC Approved Bank and does not have a Participating Bank Issuer, then Alterra Capital may, at its sole expense and effort (but subject to all rights that Alterra Capital may have against a Defaulting Lender), upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.06), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(a) Alterra Capital shall have paid to the Administrative Agent the assignment fee specified in Section 11.06(b);

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or Alterra Capital (in the case of all other amounts) and any outstanding Several Letters of Credit have been amended or returned and reissued to reflect such assignment;

(c) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter;

The obligation of each Borrower in respect of any such sum due from it to the Administrative Agent or the Lenders hereunder or under the other Loan Documents shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the Administrative Agent of any sum adjudged to be so due in the Judgment Currency, the Administrative Agent may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the sum

113

originally due to the Administrative Agent from any Borrower in the Agreement Currency, such Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent or the Person to whom such obligation was owing against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Administrative Agent in such currency, the Administrative Agent agrees to return the amount of any excess to such Borrower (or to any other Person who may be entitled thereto under applicable Law).

114

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.
