SECTION 4. DIVIDENDS.

(a) RATE. Holders of Series C Preferred Shares shall be entitled to receive, only when, as and if declared by the Board of Directors or a duly authorized committee of the Board of Directors, out of available funds for the payment of dividends under Bermuda law, non-cumulative cash dividends at the annual rate of 6.350% applied to the liquidation preference amount of US$25,000 per share of Series C Preferred Shares. Such dividends shall be payable quarterly in arrears (as provided below in this Section 4(a)), but only when, as and if declared by the Board of Directors or a duly authorized committee of the Board of Directors, on March 15, June 15, September 15 and December 15 of each year (each, a “Dividend Payment Date”), commencing on March 15, 2016; provided that if any such Dividend Payment Date would otherwise occur on a day that is not a Business Day, such Dividend Payment Date shall instead be (and any dividend payable on the Series C Preferred Shares on such Dividend Payment Date shall instead be payable on) the immediately succeeding Business Day.

Dividends, if so declared, that are payable on Series C Preferred Shares on any Dividend Payment Date will be payable to holders of record of Series C Preferred Shares as they appear on the share register of the Company on the applicable record date, which shall be the 15th calendar day before such Dividend Payment Date or such other record date fixed by the Board of Directors or a duly authorized committee of the Board of Directors that is not more than 60 nor less than 10 days prior to such Dividend Payment Date (each, a “Dividend Record Date”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day.

3

Each dividend period (a “Dividend Period”) shall commence on and include a Dividend Payment Date (other than the initial Dividend Period, which shall commence on and include the date of original issue of the Series C Preferred Shares, provided that, for any Series C Preferred Shares issued after such original issue date, the initial Dividend Period for such shares may commence on and include such other date as the Board of Directors or a duly authorized committee of the Board of Directors shall determine and publicly disclose at the time such additional shares are issued) and shall end on and include the calendar day preceding the next Dividend Payment Date. Dividends payable on the Series C Preferred Shares in respect of any Dividend Period shall be computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends payable in respect of a Dividend Period shall be payable in arrears (i.e., on the first Dividend Payment Date after such Dividend Period).

Dividends on the Series C Preferred Shares shall be non-cumulative. Accordingly, if the Board of Directors or a duly authorized committee of the Board of Directors does not declare a dividend on the Series C Preferred Shares payable in respect of any Dividend Period before the related Dividend Payment Date, in full or otherwise, then such undeclared dividends shall not cumulate and will not accrue and will not be payable and the Company shall have no obligation to pay such undeclared dividends for the applicable Dividend Period on the related Dividend Payment Date or at any future time or to pay interest with respect to such dividends, whether or not dividends are declared on Series C Preferred Shares or any other preference shares the Company may issue in the future.

Holders of Series C Preferred Shares shall not be entitled to any dividends or other distributions, whether payable in cash, securities or other property, other than dividends (if any) declared and payable on the Series C Preferred Shares as specified in this Section 4 (subject to the other provisions of this Certificate of Designations).

(b) PRIORITY OF DIVIDENDS. So long as any Series C Preferred Shares remain outstanding, unless full dividends on all outstanding Series C Preferred Shares and any Parity Shares payable on a Dividend Payment Date have been declared and paid (or declared and a sum sufficient for the payment thereof has been set aside), (1) no dividend shall be declared or paid on the Ordinary Shares or any other Junior Shares (other than a dividend payable solely in Ordinary Shares or in other Junior Shares) during the following Dividend Period, and (2) no Ordinary Shares or other Junior Shares shall be purchased, redeemed or otherwise acquired for consideration by the Company, directly or indirectly (other than (i) as a result of a reclassification of Junior Shares for or into other Junior Shares, or the exchange or conversion of one Junior Share for or into another Junior Share, (ii) through the use of the proceeds of a substantially contemporaneous sale of Junior Shares and (iii) as permitted by the Bye-Laws in effect on the date of issuance of the Series C Preferred Shares).

When dividends are not paid (or declared and a sum sufficient for payment thereof set aside) in full on any Dividend Payment Date (or, in the case of Parity Shares having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within a Dividend Period) upon the Series C Preferred Shares and any Parity Shares, all dividends declared by the Board of Directors or a duly authorized committee thereof on the Series C Preferred Shares and all such Parity Shares and payable on such Dividend Payment Date (or, in the case of Parity Shares having dividend payment dates different from the Dividend

4

Payment Dates, on a dividend payment date falling within the Dividend Period related to such Dividend Payment Date) shall be declared by the Board of Directors or such committee of the Board of Directors pro rata in accordance with the respective aggregate liquidation preference of the Series C Preferred Shares and any Parity Shares so that the respective amounts of such dividends shall bear the same ratio to each other as all declared but unpaid dividends per share on the Series C Preferred Shares and all Parity Shares payable on such Dividend Payment Date (or, in the case of Parity Shares having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such Dividend Payment Date) bear to each other.

(c) RESTRICTIONS ON PAYMENT OF DIVIDENDS. Pursuant to and subject to the Companies Act, the Company may not lawfully declare or pay a dividend if the Company has reasonable grounds for believing that the Company is, and would after payment of the dividend be, unable to pay its liabilities as they become due, or that the realizable value of the Company’s assets would, after payment of the dividend, be less than the aggregate value of the Company’s liabilities, issued share capital and share premium accounts.

SECTION 5. PAYMENT OF ADDITIONAL AMOUNTS.

(a) The Company will make all payments on the Series C Preferred Shares free and clear of and without withholding or deduction at source for, or on account of, any present or future taxes, fees, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any relevant taxing jurisdiction, unless such taxes, fees, duties, assessments or governmental charges are required to be withheld or deducted by (x) the laws (or any regulations or rulings promulgated thereunder) of any relevant taxing jurisdiction or (y) an official position regarding the application, administration, interpretation or enforcement of any such laws, regulations or rulings (including, without limitation, a holding by a court of competent jurisdiction or by a taxing authority in any relevant taxing jurisdiction). If a withholding or deduction at source is required, the Company will, subject to certain limitations and exceptions described below, pay to the holders of the Series C Preferred Shares such additional amounts as dividends as may be necessary so that the net amounts paid will be equal to the amounts the Company would otherwise have been required to pay had no such withholding or deduction been required.

(b) The Company will not be required to pay any additional amounts for or on account of:

(i) any tax, fee, duty, assessment or governmental charge of whatever nature that would not have been imposed but for the fact that such holder was a resident, domiciliary or national of, or engaged in business or maintained a permanent establishment or was physically present in, the relevant taxing jurisdiction or any political subdivision thereof or otherwise had some connection with the relevant taxing jurisdiction other than by reason of the mere ownership of, or receipt of payment under, such Series C Preferred Shares or any Series C Preferred Shares presented for payment more than 30 days after the Relevant Date (except to the extent that the holder would have been entitled to such amounts if it had presented such shares for payment on any day within such 30 day period). The “Relevant Date” means, in respect of any payment,

5

the date on which such payment first becomes due and payable, but if the full amount of the moneys payable has not been received by the dividend disbursing agent on or prior to such due date, it means the first date on which, the full amount of such moneys having been so received and being available for payment to holders, notice to that effect shall have been duly given to the holders of the Series C Preferred Shares;

(ii) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge or any tax, assessment or other governmental charge that is payable otherwise than by withholding or deduction from payment of the liquidation preference or of any dividends on the Series C Preferred Shares;

(iii) any tax, fee, duty, assessment or other governmental charge that is imposed or withheld by reason of the failure by the holder of such Series C Preferred Shares to comply with any reasonable request by the Company addressed to the holder within 90 days of such request (a) to provide information concerning the nationality, residence or identity of the holder or (b) to make any declaration or other similar claim or satisfy any information or reporting requirement, which is required or imposed by statute, treaty, regulation or administrative practice of the relevant taxing jurisdiction as a precondition to exemption from all or part of such tax, fee, duty, assessment or other governmental charge; or

(iv) any combination of items (i), (ii) and (iii).

(c) In addition, the Company will not pay additional amounts with respect to any payment on any such Series C Preferred Shares to any holder who is a fiduciary, partnership, limited liability company or other pass-through entity other than the sole beneficial owner of such Series C Preferred Shares if such payment would be required by the laws of the relevant taxing jurisdiction to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership, limited liability company or other pass-through entity or a beneficial owner to the extent such beneficiary, partner or settlor would not have been entitled to such additional amounts had it been the holder of the Series C Preferred Shares.

SECTION 6. LIQUIDATION RIGHTS.

(a) VOLUNTARY OR INVOLUNTARY LIQUIDATION. In the event of any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, holders of Series C Preferred Shares shall be entitled to receive, out of the assets of the Company or proceeds thereof (whether capital or surplus) available for distribution to shareholders of the Company, after satisfaction of all liabilities and obligations to creditors of the Company, if any, but before any distribution of such assets or proceeds is made to or set aside for the holders of Ordinary Shares and any other Junior Shares, in full an amount equal to US$25,000 per Series C Preferred Share, plus declared and unpaid dividends, if any.

6

(b) PARTIAL PAYMENT. If in any distribution described in Section 6(a) above, the assets of the Company or proceeds thereof are not sufficient to pay the Liquidation Preferences (as defined below) in full to all holders of Series C Preferred Shares and all holders of any Parity Shares, the amounts paid to the holders of Series C Preferred Shares and to the holders of all such other Parity Shares shall be paid pro rata in accordance with the respective aggregate Liquidation Preferences of the holders of Series C Preferred Shares and the holders of all such other Parity Shares but only to the extent the Company has assets or proceeds thereof available after satisfaction of all liabilities to creditors. In any such distribution, the “Liquidation Preference” of any holder of Preferred Shares of the Company shall mean the amount otherwise payable to such holder in such distribution (assuming no limitation on the assets of the Company available for such distribution), including any declared and unpaid dividends (and, in the case of any holder of shares other than Series C Preferred Shares and on which dividends accrue on a cumulative basis, an amount equal to any unpaid, accrued cumulative dividends, whether or not declared, as applicable).

(c) RESIDUAL DISTRIBUTIONS. If the Liquidation Preference has been paid in full to all holders of Series C Preferred Shares and any holders of Parity Shares, the holders of other shares of the Company shall be entitled to receive all remaining assets of the Company (or proceeds thereof) according to their respective rights and preferences.

(d) MERGER, CONSOLIDATION AND SALE OF ASSETS NOT LIQUIDATION. For purposes of this Section 6, the consolidation, amalgamation, merger, arrangement, reincorporation, de-registration or reconstruction involving the Company or the sale or transfer of all or substantially all of the shares or the property or business of the Company shall not be deemed to constitute a liquidation, dissolution or winding-up.

SECTION 7. REDEMPTION.

(a) OPTIONAL REDEMPTION.

(1) The Series C Preferred Shares may not be redeemed by the Company prior to December 15, 2020, subject to the exceptions set forth in Section 7(a)(2) and Section 7(f) and (g). On or after December 15, 2020, the Company, at its option, may redeem, in whole at any time or in part from time to time, the shares of Series C Preferred Shares at the time outstanding, upon notice given as provided in Section 7(c) below, at a redemption price equal to US$25,000 per share, together (except as otherwise provided herein below) with an amount equal to any dividends that have been declared but not paid prior to the redemption date (but with no amount in respect of any dividends that have not been declared prior to such date). The redemption price for any shares of Series C Preferred Shares shall be payable on the redemption date to the holder of such shares against book-entry transfer or surrender of the certificate(s) evidencing such shares to the Company or its agent. Any declared but unpaid dividends payable on a redemption date that occurs subsequent to the Dividend Record Date for a Dividend Period shall not be paid to the holder entitled to receive the redemption price on the redemption date, but rather shall be paid to the holder of record of the redeemed shares on such Dividend Record Date relating to the Dividend Payment Date as provided in Section 4 above.

Prior to delivering notice of redemption as provided below, the Company will file with its corporate records a certificate signed by one of the Company’s officers affirming the Company’s compliance with the redemption provisions under the Companies Act relating to the Series C Preferred Shares, and stating that there are reasonable grounds for believing that the

7

Company is, and after the redemption will be, able to pay its liabilities as they become due and that the redemption will not render the Company insolvent or cause it to breach any provision of applicable Bermuda law or regulation. The Company will mail a copy of this certificate with the notice of any redemption.

(2) At any time prior to December 15, 2020, if the Company shall have submitted to the holders of Ordinary Shares a proposal for an amalgamation, consolidation, merger, arrangement, reconstruction, reincorporation, deregistration or any other similar transaction involving the Company that requires, or the Company shall have submitted any proposal for any other matter that, as a result of any change in Bermuda law after such Series C Preferred Shares are issued (whether by enactment or official interpretation), that requires, in either case, a vote of the holders of the Series C Preferred Shares at the time outstanding, voting separately as a single class (alone or with one or more other classes or series of preference shares), the Company shall have the option, by not less than 30 days nor more than 60 days prior written notice, to the relevant holders, in such form and given in such manner as to be in accordance with Section 7(c) below, to redeem all and not less than all of the outstanding Series C Preferred Shares pursuant to this clause for cash at a redemption price of US$26,000 per share being redeemed, plus all declared and unpaid dividends, if any, to the date of redemption, without interest on such unpaid dividends.

(b) NO SINKING FUND. The Series C Preferred Shares will not be subject to any mandatory redemption, sinking fund, retirement fund or purchase fund or other similar provisions. Holders of Series C Preferred Shares will have no right to require redemption, repurchase or retirement of any shares of Series C Preferred Shares.

(c) NOTICE OF REDEMPTION. Notice of every redemption of Series C Preferred Shares shall be given by first class mail, postage prepaid, addressed to the holders of record of the shares to be redeemed at their respective last addresses appearing on the share register of the Company. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this subsection shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of Series C Preferred Shares designated for redemption shall not affect the validity of the proceedings for the redemption of any other Series C Preferred Shares. Notwithstanding the foregoing, if the Series C Preferred Shares or any depositary shares representing interests in the Series C Preferred Shares are issued in book-entry form through DTC or any other similar facility, notice of redemption may be given to the holders of Series C Preferred Shares at such time and in any manner permitted by such facility. Each such notice given to a holder shall state: (1) the redemption date; (2) the number of Series C Preferred Shares to be redeemed and, if less than all the Series C Preferred Shares held by such holder are to be redeemed, the number of such Series C Preferred Shares to be redeemed from such holder; (3) the redemption price; and (4) that the Series C Preferred Shares should be delivered via book-entry transfer or the place or places where certificates for such Series C Preferred Shares are to be surrendered for payment of the redemption price.

8

(d) PARTIAL REDEMPTION. In case of any redemption of only part of the Series C Preferred Shares at the time outstanding, the shares to be redeemed shall be selected either pro rata or in such other manner as the Company may determine to be fair and equitable. Subject to the provisions hereof, the Company shall have full power and authority to prescribe the terms and conditions upon which Series C Preferred Shares shall be redeemed from time to time. If fewer than all the shares represented by any certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without charge to the holder thereof.

(e) EFFECTIVENESS OF REDEMPTION. If notice of redemption has been duly given and if on or before the redemption date specified in the notice all funds necessary for the redemption have been set aside by the Company, separate and apart from its other funds, in trust for the pro rata benefit of the holders of the Series C Preferred Shares called for redemption, so as to be and continue to be available therefor, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation or transferred via book-entry, on and after the redemption date, no further dividends will be declared on all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption, without interest.

(f) REDEMPTION UPON CAPITAL DISQUALIFICATION EVENT. At any time within 90 days following the occurrence of the date (a “Capital Redemption Trigger Date”) on which the Company has reasonably determined that, as a result of:

(i) any amendment to, or change in, the laws or regulations of Bermuda that is enacted or becomes effective after the initial issuance of the Series C Preferred Shares;

(ii) any proposed amendment to, or change in, the laws or regulations of Bermuda that is announced or becomes effective after the initial issuance of the Series C Preferred Shares; or

(iii) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying the laws or regulations of Bermuda that is announced after the initial issuance of the Series C Preferred Shares, a Capital Disqualification Event has occurred;

the Series C Preferred Shares will be redeemable at the Company’s option, in whole or in part, upon notice given as provided in Section 7(c), at a redemption price equal to US$25,000 per Series C Preferred Share, plus all declared and unpaid dividends, if any, to, but excluding, the date of redemption, without accumulation of any undeclared dividends; provided that any such redemption in part may only be made if (x) the Company has reasonably determined that the portion of the Series C Preferred Shares to be redeemed are the subject of the Capital Disqualification Event and (y) after giving effect to such redemption, the Company has reasonably determined that a Capital Disqualification Event will not exist with respect to the then-outstanding Series C Preferred Shares and such redemption will not result in the suspension or removal of the depositary shares representing the Series C Preferred Shares from listing on the New York Stock Exchange.

9

(g) TAX REDEMPTION. (1) If as a result of a “change in tax law” there is a substantial probability that the Company or any successor company would be required to pay additional amounts with respect to the Series C Preferred Shares on the next succeeding Dividend Payment Date, and the payment of those additional amounts cannot be avoided by the use of any reasonable measures available to the Company or any successor company (a “Tax Event”), the Company shall be entitled at any time thereafter, by not less than 30 days nor more than 60 days prior written notice to the relevant holders of the Series C Preferred Shares in such form and given in such manner as in accordance with Section 7(c) above, to redeem all Series C Preferred Shares pursuant to this clause for cash at a redemption price of US$25,000 per share, plus all declared and unpaid dividends, if any, to the date of redemption, without interest on such unpaid dividends. A “change in tax law” shall be (a) a change in or amendment to laws, regulations or rulings of any relevant taxing jurisdiction, (b) a change in the official application or interpretation of those laws, regulations or rulings, (c) any execution of or amendment to any treaty affecting taxation to which any relevant taxing jurisdiction is party or (d) a decision rendered by a court of competent jurisdiction in any relevant taxing jurisdiction, whether or not such decision was rendered with respect to the Company, in each case described in clauses (a) – (d) above, occurring after November 17, 2015. As used herein, a “relevant taxing jurisdiction” is (a) Bermuda or any political subdivision or governmental authority of or in Bermuda with the power to tax, (b) any jurisdiction from or through which the Company or its dividend disbursing agent is making payments on the Series C Preferred Shares or any political subdivision or governmental authority of or in that jurisdiction with the power to tax, or (c) any other jurisdiction in which the Company or any successor company is organized or generally subject to taxation or any political subdivision or governmental authority of or in that jurisdiction with the power to tax.

(2) If there is a substantial probability that the entity formed by a consolidation, merger or amalgamation involving the Company or the entity to which the Company conveys, transfers or leases substantially all of its properties and assets will be required to pay additional amounts in respect of any tax, assessment or governmental charge imposed on any holder of Series C Preferred Shares as a result of a change in tax law that occurred after the date of the consolidation, merger, amalgamation, conveyance, transfer or lease, and the payment of those additional amounts cannot be avoided by the use of any reasonable measures available to the Company or any successor company, the Company shall be entitled at any time thereafter by not less than 30 days nor more than 60 days prior written notice to the relevant holders of Series C Preferred Shares, in such form and given in such manner as in accordance with Section 7(c) above, to redeem, in whole, the Series C Preferred Shares pursuant to this clause for cash at a redemption price of US$25,000 per share, plus all declared and unpaid dividends, if any, to the date of redemption, without interest on such unpaid dividends.

SECTION 8. SUBSTITUTION OR VARIATION

(a) In lieu of redemption, at any time following a Tax Event or at any time following a Capital Disqualification Event, the Company may, without the consent of any holders of the Series C Preferred Shares, vary the terms of the Series C Preferred Shares such that they remain securities, or exchange the Series C Preferred Shares with new securities, which (i) in the case of a Tax Event, would eliminate the substantial probability that the Company or any successor corporation would be required to pay any additional amounts with respect to the

10

Series C Preferred Shares as a result of a change in tax law, or (ii) in the case of a Capital Disqualification Event, for purposes of determining the solvency margin, capital adequacy ratios or any other comparable ratios, regulatory capital resource or level of the Company or any member thereof, where subdivided into tiers, qualify as Tier 1 or Tier 2 capital securities under then-applicable Capital Adequacy Regulations imposed upon the Company by the BMA (or any successor agency or then-applicable regulatory authority) which may include enhanced capital adequacy regulation designed to achieve full equivalency under the Solvency II Directive (Directive 2009/13/EC) and, which includes the Company’s individual and group Enhanced Capital Requirements. In either case, the terms of the varied securities or new securities considered in the aggregate cannot be less favorable to holders than the terms of the Series C Preferred Shares prior to being varied or exchanged; provided that no such variation of terms or securities received in exchange shall change the specified denominations of, dividend payable on, the redemption dates (other than any extension of the period during which an optional redemption may not be exercised by the Company) or currency of, the Series C Preferred Shares, reduce the liquidation preference thereof, lower the ranking in right of payment with respect to the payment of dividends or the distribution of assets upon liquidation, dissolution or winding-up of the Series C Preferred Shares, or change the foregoing list of items that may not be so amended as part of such variation or exchange. Further, no such variation of terms or securities received in exchange shall impair the right of a holder of the securities to institute suit for the payment of any amounts due (as provided under this Certificate of Designations), but unpaid with respect to such holder’s securities.

(b) Prior to any variation or exchange, the Company will be required to receive an opinion of independent legal advisers of recognized standing to the effect that holders and beneficial owners of the Series C Preferred Shares (including as holders and beneficial owners of the varied or exchanged securities) will not recognize income, gain or loss for United States federal income tax purposes as a result of such variation or exchange and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case had such variation or exchange not occurred.

(c) Any variation or exchange of the Series C Preferred Shares described above will be made after notice is given to the holders of the Series C Preferred Shares not less than 30 days nor more than 60 days prior to the date fixed for variation or exchange, as applicable.

SECTION 9. VOTING RIGHTS.

(a) GENERAL. The holders of Series C Preferred Shares shall not have any voting rights except as set forth below or as otherwise from time to time required by law.

(b) RIGHT TO ELECT TWO DIRECTORS UPON NONPAYMENT EVENTS. If and whenever dividends on any Series C Preferred Shares shall not have been declared and paid for the equivalent of at least six Dividend Periods, whether or not consecutive (a “Nonpayment Event”), the holders of Series C Preferred Shares, together with the holders of any outstanding shares of Voting Preferred Shares, voting together as a single class, shall be entitled to elect two additional directors to the Board of Directors (the “Preferred Shares Directors”), provided that it shall be a qualification for election for any such Preferred Shares

11

Director that the election of such director shall not cause the Company to violate the corporate governance requirements of the U.S. Securities and Exchange Commission or the New York Stock Exchange (or any other securities exchange or other trading facility on which securities of the Company may then be listed or traded) that listed or traded companies must have a majority of independent directors. Each Preferred Shares Director will be added to an already existing class of directors. The number of Preferred Shares Directors on the Board of Directors shall never be more than two at any one time.

In the event that the holders of the Series C Preferred Shares, and any such other holders of Voting Preferred Shares, shall be entitled to vote for the election of the Preferred Shares Directors following a Nonpayment Event, such directors shall be initially elected following such Nonpayment Event only at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series C Preferred Shares or of any other such series of Voting Preferred Shares then outstanding (unless such request for a special meeting is received less than 90 days before the date fixed for the next annual or special meeting of the shareholders of the Company, in which event such election shall be held only at such next annual or special general meeting of shareholders), and at each subsequent annual general meeting of shareholders of the Company, so long as the rights related to a Nonpayment Event remain in effect. Such request to call a special general meeting for the initial election of the Preferred Shares Directors after a Nonpayment Event shall be made by written notice, signed by the requisite holders of Series C Preferred Shares or Voting Preferred Shares, and delivered to the Secretary of the Company in person, by first class mail, by any manner as permitted in the Bye-laws or by any other manner as permitted by Bermuda law. Each Preferred Shares Director will be added to an already existing class of directors. The number of Preferred Share Directors shall never be more than two at any one time.

When dividends have been paid (or declared and a sum sufficient for payment thereof set aside) in full on the Series C Preferred Shares for at least four consecutive Dividend Periods after a Nonpayment Event, then the right of the holders of Series C Preferred Shares to elect the Preferred Shares Directors shall cease (but subject always to revesting of such voting rights in the case of any future Nonpayment Event pursuant to this Section 9) and the number of Dividend Periods in which dividends have not been declared and paid shall be reset to zero, and, if and when any rights of holders of Series C Preferred Shares and Voting Preferred Shares to elect the Preferred Shares Directors shall have ceased, the terms of office of all the Preferred Shares Directors shall forthwith terminate and the number of directors constituting the Board of Directors shall automatically be reduced accordingly.

Any Preferred Shares Director may be removed at any time without cause by the holders of record of a majority of the aggregate voting power, as determined by the Bye-laws of the Company, of Series C Preferred Shares and Voting Preferred Shares then outstanding (voting together as a single class), when they have the voting rights described above. Until the right of the holders of Series C Preferred Shares and any Voting Preferred Shares to elect the Preferred Shares Directors shall cease, any vacancy in the office of a Preferred Shares Director (other than prior to the initial election of Preferred Shares Directors after a Nonpayment Event) may be

12

filled by the written consent of the Preferred Shares Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding shares of the Series C Preferred Shares and any Voting Preferred Shares (voting together as a single class), when they have the voting rights described above. Any such vote of holders of Series C Preferred Shares and Voting Preferred Shares to remove, or to fill a vacancy in the office of, a Preferred Shares Director may be taken only at a special meeting of such shareholders, called as provided above for an initial election of Preferred Shares Directors after a Nonpayment Event (unless such request is received less than 90 days before the date fixed for the next annual or special general meeting of the shareholders of the Company, in which event such election shall be held at such next annual or special general meeting of shareholders). The Preferred Shares Directors shall each be entitled to one vote per director on any matter that shall come before the Board of Directors for a vote, unless otherwise adjusted pursuant to the Bye-Laws. Each Preferred Shares Director elected at any special general meeting of shareholders of the Company or by written consent of the other Preferred Shares Director shall hold office until the next annual general meeting of the shareholders of the Company if such office shall not have previously terminated as above provided.

(c) VARIATION OF RIGHTS. Other than as provided for in Section 8(a) (which permits certain variations without consent by the holders of the Series C Preference Shares), any or all of the special rights of the Series C Preferred Shares may be altered or abrogated with the consent in writing of the holders of not less than seventy-five percent (75%) of the issued shares of that class or with the sanction of a resolution passed at a separate general meeting of the holders by not less than seventy-five percent (75%) of such shares voting in person or proxy. The necessary quorum requirements for the separate general meeting shall be two or more persons holding or representing by proxy more than fifty percent (50%) of the aggregate voting power of the shares of the relevant class. The rights attaching to or the terms of issue of such shares or class of shares, as the case may be, shall not be deemed to be altered by (i) the creation or issue of further shares ranking pari passu therewith; (ii) the creation or issue for full value (as determined by the Board of Directors) of further shares ranking as regards participation in profits or assets of the Company or otherwise in priority to them; or (iii) the purchase or redemption by the Company of any of its own shares.

(d) CHANGES FOR CLARIFICATION. Without the consent of the holders of the Series C Preferred Shares, so long as such action does not affect the special rights, preferences, privileges and voting powers, and limitations and restrictions, of the Series C Preferred Shares taken as a whole, the Company may amend, alter, supplement or repeal any terms of the Series C Preferred Shares:

(i) to cure any ambiguity, or to cure, correct or supplement any provision contained in this Certificate of Designations that may be defective or inconsistent; or

(ii) to make any provision with respect to matters or questions arising with respect to the Series C Preferred Shares that is not inconsistent with the provisions of this Certificate of Designations.

13

(e) CHANGES AFTER PROVISION FOR REDEMPTION. No vote or consent of the holders of Series C Preferred Shares shall be required pursuant to Section 9(b), (c) or (d) above if, at or prior to the time when the act with respect to which such vote or consent would otherwise be required pursuant to such Section shall be effected, all outstanding Series C Preferred Shares shall have been redeemed, or shall have been called for redemption upon proper notice and sufficient funds shall have been set aside by the Company for such redemption, in each case pursuant to Section 8 above.

(f) PROCEDURES FOR VOTING AND CONSENTS. The rules and procedures for calling and conducting any meeting of the holders of Series C Preferred Shares (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules the Board of Directors or a duly authorized committee of the Board of Directors, in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Memorandum of Association, the Bye-Laws, applicable law and any national securities exchange or other trading facility on which the Series C Preferred Shares is listed or traded at the time. Whether the vote or consent of the holders of a plurality, majority or other portion of the shares of Series C Preferred Shares and any Voting Preferred Shares has been cast or given on any matter on which the holders of shares of Series C Preferred Shares are entitled to vote shall be determined by the Company by reference to the aggregate voting power, as determined by the Bye-laws of the Company, of the shares voted or covered by the consent.

SECTION 10. RANKING. The Series C Preferred Shares will, with respect to the payment of dividends and distributions of assets upon liquidation, dissolution and winding-up, rank senior to Junior Shares and pari passu with any Parity Shares of the Company, including other series of Preferred Shares of the Company that the Company may issue from time to time in the future.

SECTION 11. RECORD HOLDERS. To the fullest extent permitted by applicable law, the Company and the transfer agent for the Series C Preferred Shares may deem and treat the record holder of any share of Series C Preferred Shares as the true and lawful owner thereof for all purposes, and neither the Company nor such transfer agent shall be affected by any notice to the contrary.

SECTION 12. NOTICES. All notices or communications in respect of Series C Preferred Shares shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Certificate of Designations, Bye-Laws or by applicable law. Notwithstanding the foregoing, if Series C Preferred Shares or depositary shares representing an interest in Series C Preferred Shares are issued in book-entry form through DTC, such notices may be given to the holders of the Series C Preferred Shares in any manner permitted by DTC.

SECTION 13. NO PREEMPTIVE RIGHTS. No share of Series C Preferred Shares shall have any rights of preemption whatsoever as to any securities of the Company, or any warrants, rights or options issued or granted with respect thereto, regardless of how such securities, or such warrants, rights or options, may be designated, issued or granted.

14

SECTION 14. OTHER RIGHTS. The shares of Series C Preferred Shares shall not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth herein or in the Memorandum of Association, Bye-laws or as provided by applicable law.
