ARTICLE II

CONVERSION OF COMPANY SECURITIES; EXCHANGE OF CERTIFICATES

Section 2.1Effect on Share Capital. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of the holders of any common shares of the Company, each having a par value of US$1.00 (each, a “Company Common Share”), as evidenced by share certificates registered in the name of a shareholder and representing outstanding Company Common Shares (each, a “Company Certificate”) and by way of entry in the register of shareholders of the Company (the “Company Share Register”):

(a)Conversion of Company Common Shares. Each Company Common Share issued and outstanding immediately before the Effective Time (other than Dissenting Shares) shall be cancelled and converted into the right to receive (A) 0.04315 (the “Exchange Ratio”) validly issued, fully paid and non-assessable Parent voting common shares, without par value (each, a “Parent Common Share”), together with any cash paid in lieu of fractional shares in

accordance withSection 2.2(e) (collectively, the “Stock Consideration”) and (B) $10.00 in cash, without interest (the “Cash Consideration”, and together with the Stock Consideration, the “Consideration”). Upon such conversion, each Company Common Share shall be cancelled and each holder of a Company Common Shares registered in the Company Share Register immediately before the Effective Time shall thereafter cease to have any rights with respect to such Company Common Shares except the right to receive the Consideration. The Consideration shall be appropriately adjusted to reflect fully the effect of any stock split, reverse stock split, stock dividend (including any dividend or similar distribution of securities convertible into Parent Common Shares or Company Common Shares), reorganization, recapitalization, reclassification or other like change with respect to Parent Common Shares or Company Common Shares having a record date on or following the date hereof and before the Effective Time, it being understood that (i) the intent of such adjustment is to provide the holders of Company Common Shares with the same economic effect as contemplated by this Agreement and the Merger Agreement before any such change and (ii) nothing in thisSection 2.1(a) shall be construed to permit the Company or Parent to take any action with respect to its securities that is prohibited by the terms of this Agreement or the Merger Agreement.

(b)Cancellation of Parent-Owned Securities. Notwithstanding anything in this Agreement to the contrary, all Company Common Shares that are held by the Company as treasury stock or owned by Parent or by any Subsidiary of Parent immediately before the Effective Time shall, by virtue of the Merger, and without any action on the part of the holder thereof, automatically be cancelled and retired without any conversion thereof and shall cease to exist, and no payment shall be made in respect thereof.

(c)Shares of Dissenting Holders. Notwithstanding anything in this Agreement to the contrary, any Dissenting Shares shall be cancelled and converted into the right to receive the fair value thereof under section 106(2) of the Companies Act. The Company shall give Parent (i) prompt notice of (A) any demands for appraisal of Dissenting Shares or attempted withdrawal or withdrawals of such demands received by the Company and any other instruments served under the Companies Act and received by the Company relating to any Dissenting Shareholder’s right to be paid the fair value of such Dissenting Shareholder’s Dissenting Shares and (B) to the extent that the Company has Knowledge, any applications to the Supreme Court of Bermuda for appraisal of the fair value of the Dissenting Shares and (ii) to the extent permitted by applicable Law, the opportunity to participate with the Company in any and all negotiations and proceedings with respect to any written demands for appraisal under the Companies Act. Neither the Company nor Parent shall, without the prior written consent of the other party, voluntarily make any payment with

respect to, or settle, or offer to settle, any such demands or applications, or waive any failure to timely deliver a written demand for appraisal or timely take any other action to perfect appraisal rights in accordance with the Companies Act.

(d) Each common share of the Merger Sub issued and outstanding immediately before the Effective Time shall be converted into one validly issued, fully paid and non-assessable share, par value US$1.00 per share, of the Surviving Company.

Section 2.2Exchange Procedures.

(a)Exchange Agent. At least five Business Days before the Effective Time, Parent shall designate an exchange and paying agent reasonably acceptable to the Company (the “Exchange Agent”) for the purpose of exchanging Company Common Shares outstanding immediately before the Effective Time. On the Closing Date, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent in accordance with thisArticle II, (i) certificates, or at Parent’s option, shares in book-entry form representing Parent Common Shares to be exchanged in the Merger and (ii) cash (which, for the avoidance of doubt may include the proceeds of the Alterra Insurance Company Dividend) in an amount sufficient to pay the aggregate Cash Consideration payable underSection 2.1(a) and any cash payable in lieu of fractional shares underSection 2.2(e). Following the Effective Time, Parent shall deposit promptly, or cause to be deposited, with the Exchange Agent cash in respect of any dividends or distributions to which the shareholders of the Company may be entitled underSection 2.2(c) in an amount sufficient to pay such dividends or distributions to shareholders of the Company that have not, as of such date, exchanged their Company Common Shares. Such Consideration and cash so deposited are hereinafter referred to as the “Exchange Fund.” No interest shall be paid or accrued for the benefit of holders of the Company Common Shares on cash amounts payable under thisSection 2.2. The Exchange Agent shall invest any cash in the Exchange Fund as directed by Parent;provided that such investments shall be in direct obligations of or fully guaranteed by the United States of America or in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of investment. Any interest and other income resulting from such investments shall be promptly paid to Parent and any amounts in excess of the amounts payable underSection 2.2(b),2.2(c) and2.2(e) shall be promptly returned to Parent. To the extent that there are any losses with respect to any such investments, or such cash diminishes for any reason below the level required for the Exchange Agent to make prompt cash payment of amounts underSection 2.2(b),2.2(c) and2.2(e), Parent shall promptly replace or restore the cash so as to ensure that there is sufficient cash for the Exchange Agent to make all such payments.

(b)Exchange Procedures. Promptly following the Effective Time and in any event not later than five Business Days following the Effective Time, Parent or the Surviving Company shall cause the Exchange Agent to mail, to each shareholder of the

Company, (i) a letter of transmittal (which shall be in such form and have such other provisions as the parties may reasonably specify at least three Business Days before the Effective Time), and (ii) instructions for use in effecting the surrender of Company Common Shares in exchange for the Consideration. Following the Effective Time, upon surrender of title to the Company Common Shares previously held by a shareholder of the Company in accordance with thisSection 2.2, together with such letter of transmittal duly executed and such other documents as the Exchange Agent may reasonably require, a holder of Company Common Shares shall be entitled to receive in exchange therefor (A) a certificate or book-entry representing that number of whole Parent Common Shares (rounded down) which such shareholder has the right to receive in respect of the Company Common Shares after taking into account all Company Common Shares then held by such shareholder, (B) any cash in lieu of fractional shares that such shareholder has the right to receive underSection 2.2(e) and (C) the amount of the Cash Consideration which such shareholder has the right to receive in respect of the Company Common Shares and any Company Certificate surrendered in respect thereof shall forthwith be marked as cancelled. In the event of a transfer of ownership of Company Common Shares that is not registered in the transfer records of the Company, a certificate or book-entry representing the proper number of Parent Common Shares may be issued to a transferee if the Company Certificate representing such Company Common Shares (if any) is presented to the Exchange Agent, accompanied by documents normally required to evidence and effect such transfer (reasonably satisfactory to Parent) and by reasonable evidence that any applicable stock transfer taxes have been paid.

(c)Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made with respect to Parent Common Shares with a record date on or following the Effective Time shall be paid to any shareholder of the Company holding any unexchanged Company Common Shares with respect to Parent Common Shares represented thereby, nor shall any Cash Consideration or the cash payment in lieu of fractional shares be paid to any such shareholder underSection 2.2(e), until such shareholder shall exchange such Company Common Shares in accordance with the procedures set forth in thisArticle II. Following the exchange of any such Company Common Shares in accordance with the procedures set forth in thisArticle II, such shareholder shall be entitled to receive, in addition to the Consideration set forth inSection 2.1(a), without interest, (i) at the time of such exchange, the amount of any dividends or other distributions with a record date on or following the Effective Time theretofore paid (but withheld under the immediately preceding sentence) with respect to such whole Parent Common Shares that a shareholder holding such Company Common Shares is entitled to receive hereunder and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date on or following the Effective Time but before exchange and a payment date after the exchange payable with respect to such whole Parent Common Shares that a shareholder holding such Company Common Shares is entitled to receive hereunder.

(d)No Further Rights in Company Common Shares. All Consideration paid or issued upon the surrender of title to Company Common Shares in accordance with the terms of thisArticle II (including any cash paid under thisArticle II) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shareholders of the Company in their capacity as shareholders of the Company before the Effective Time. There shall be no further registration of transfers on the share transfer books of the Surviving Company of the Company Common Shares that were outstanding immediately before the Effective Time. If, after the Effective Time, Company Certificates are presented to Parent or to the Surviving Company or to the Exchange Agent for any reason, they shall be marked as cancelled and exchanged in accordance with thisArticle II, except as otherwise required by applicable Law.

(e)No Fractional Shares. Notwithstanding anything in this Agreement to the contrary, no fraction of a Parent Common Share shall be issued in connection with the Merger, and in lieu thereof any shareholder of the Company who would otherwise have been entitled to a fraction of a Parent Common Share, shall be paid upon surrender of Company Common Shares for exchange (and after taking into account and aggregating Company Common Shares represented by all Company Certificates surrendered by such holder, or as set out in the Company Share Register, as applicable) cash in an amount (without interest) equal to the product obtained by multiplying (i) the fractional share interest to which such shareholder (after taking into account and aggregating all Company Common Shares represented by all Company Certificates surrendered by such shareholder, or as set out in the Company Share Register, as applicable) would otherwise be entitled by (ii) the Average Parent Share Price.

(f)Lost, Stolen or Destroyed Certificates. If any Company Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed certificates, upon the making of an affidavit of that fact by the holder thereof, the Consideration and any dividends or other distributions as may be required under thisArticle II in respect of the Company Common Shares represented by such lost, stolen or destroyed Company Certificates;provided that Parent may, in its reasonable discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificates to deliver a bond in such sum as it may reasonably direct or otherwise indemnify Parent in a manner reasonably satisfactory to Parent against any claim that may be made against Parent or the Exchange Agent with respect to the Company Certificates alleged to have been lost, stolen or destroyed.

(g)Termination of Exchange Fund. Unless a longer period is prescribed by applicable Law or Parent’s agreement with the Exchange Agent, any portion of the Exchange Fund that remains undistributed to the shareholders of the Company for one year following the Effective Time shall be delivered to Parent, upon demand, and any shareholders of the Company who have not theretofore complied with thisArticle II shall thereafter look only to Parent for payment of their claim for the Consideration and any dividends or distributions with respect to Parent Common Shares.

(h)No Liability. To the extent permitted under applicable Law, any Consideration and any dividends or other distributions payable to any shareholder of the Company in accordance withSection 2.1(c) that remain undistributed to the shareholders of the Company shall be delivered to and become the property of Parent on the Business Day immediately before the day that such property is required to be delivered to any public official under any applicable abandoned property, escheat or similar Law. Notwithstanding anything in the Agreement to the contrary, to the extent permitted under applicable Law, none of Parent, the Merger Sub, the Surviving Company or the Exchange Agent shall be liable to any shareholder of the Company for any such property delivered to Parent or to a public official under any applicable abandoned property, escheat or similar Law.

(i)Withholding. The Exchange Agent, Parent, and the Surviving Company (without duplication) shall be entitled to deduct and withhold from the consideration otherwise payable under this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of applicable Tax Law. To the extent that amounts are so withheld by the Exchange Agent, Parent, or the Surviving Company, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. The parties agree to cooperate reasonably with each other for purposes of determining whether any Taxes are required to be withheld with respect to the Merger.

Section 2.3Treatment of Company Stock Options and other Company Stock-Based Awards.

(a) Each right to purchase Company Common Shares granted by the Company under the Company Share Plans that is outstanding and unexercised immediately before or as of the Effective Time (the “Company Stock Options”), whether or not exercisable and whether or not vested, at the Effective Time, shall remain outstanding following the Effective Time. At the Effective Time, all of the Company Stock Options shall, by virtue of the Merger and without any further action on the part of the Company or the holder thereof, be assumed in full by Parent, which shall have assumed the Company Share Plans as of the Effective Time by virtue of this Agreement and without any further action by Parent. From and after the Effective Time, all references to the Company in the Company Share Plans and in any agreement granting or governing Company Stock Options shall be deemed to refer to Parent. Each Company Stock Option assumed by Parent (each, a “Company Converted Option”) shall be converted automatically into an option to purchase Parent Common Shares upon the same terms and conditions as are in effect immediately before the Effective Time with respect to such Company Stock Option, including vesting schedule (taking into account any

accelerated vesting of such Company Stock Options as a result of the transactions contemplated hereby in accordance with their terms) and term of exercise, except (i) that each such Company Converted Option shall represent the right to acquire the number of Parent Common Shares equal to the number of Company Common Shares subject to such Company Stock Option multiplied by the Incentive Award Exchange Ratio, and (ii) that the exercise price per share of each Company Converted Option shall be an amount (rounded up to the nearest whole cent) equal to the option exercise price per share of the related Company Stock Option divided by the Incentive Award Exchange Ratio;provided that the conversion of the Company Converted Options shall in any event be in accordance with Treasury Regulation Section 1.409A-1(b)(5)(v)(D); andprovidedfurther that no fractional Parent Common Shares shall be issuable upon exercise of each Company Stock Option, and instead, at the Effective Time, such right to purchase such fractional share shall be cancelled and the Company shall pay the holder thereof the value of such fractional Parent Common Share in cash based on the Average Parent Share Price. For purposes of this Agreement, the “Incentive Award Exchange Ratio” shall be the sum of (x) plus (y), where (x) is the Exchange Ratio and (y) is the quotient of (i) the Cash Consideration divided by (ii) the Average Parent Share Price.

(b) At the Effective Time, each Company Restricted Award that does not become fully-vested on an accelerated basis as a result of the transactions contemplated hereby in accordance with their terms shall be assumed in full by Parent (each, a “Company Converted Restricted Award”) and shall be converted into the number of restricted Parent Common Shares or restricted stock units of Parent Common Shares, as applicable, equal to the number of Company Common Shares underlying such Company Restricted Award in effect immediately before the Effective Time multiplied by the Incentive Award Exchange Ratio;provided that no fractional restricted Parent Common Shares shall be issuable upon such conversion, and instead, at the Effective Time, such right to receive such fractional share shall be cancelled and the Company shall pay the holder thereof the value of such fractional Parent Common Share in cash based on the Average Parent Share Price. Each such Company Converted Restricted Award will otherwise have the same terms and conditions as the corresponding Company Restricted Award, including vesting schedule. All other Company Restricted Awards that become fully-vested on an accelerated basis as a result of the transactions contemplated hereby in accordance with their terms shall be canceled and converted into the right to receive the Consideration and each holder thereof shall thereafter cease to have any rights with respect to such Company Restricted Awards except the right to receive the Consideration. From and after the Effective Time, all references to the Company in the Company Share Plans and in any agreement granting or governing Company Converted Restricted Awards shall be deemed to refer to Parent. For the avoidance of doubt, all Company Restricted Awards that become fully-vested on an accelerated basis as a result of the transactions contemplated hereby in accordance with their terms shall be treated as Company Common Shares in accordance withSection 2.1, and awards of restricted stock and restricted stock units granted under the Company Share Plans which became vested

before the Closing Date in accordance with their terms and not on an accelerated basis as a result of the transactions contemplated hereby shall not be considered Company Restricted Awards for purposes of thisSection 2.3.

(c) Before the Closing, the board of directors of Parent (or the Compensation Committee of the board of directors of Parent) shall adopt such resolutions and take such other actions as are necessary or appropriate in order to effectuate the actions contemplated by thisSection 2.3, which such actions shall include: (i) reserving for issuance a sufficient number of Parent Common Shares for delivery upon the exercise of the Company Converted Options and the issuance of the Company Converted Restricted Awards; (ii) as promptly as practicable (and in no event later than five Business Days following the Effective Time) filing with the SEC a registration statement on Form S-8 (or any successor or other appropriate form) with respect to Parent Common Shares subject to the Company Converted Options and Company Converted Restricted Awards; and (iii) such other actions reasonably requested by the Company to give effect to the foregoing;provided that such resolutions and actions shall expressly be conditioned upon the consummation of the Merger and the other transactions contemplated hereby and shall be of no force and effect if this Agreement and the Merger Agreement are terminated. Parent shall use its reasonable best efforts to maintain the effectiveness of such registration statement for as long as any such Company Converted Options, and Company Converted Restricted Awards remain outstanding. As promptly as practicable, and in any event not later than ten Business Days following the Effective Time, Parent shall deliver, or cause to be delivered, to each holder of a Company Converted Option and Company Converted Restricted Award a reasonably detailed notice setting forth such holder’s rights thereunder. Parent shall comply with the terms of all such Company Converted Options and Company Converted Restricted Awards and shall ensure that the conversion and assumption of the Company Stock Options provided in thisSection 2.3 shall be effected in a manner consistent with the requirements of Section 409A of the Code.

(d) Before the Closing, the board of directors of the Company (or the Compensation Committee of the board of directors of the Company) shall adopt such resolutions and take such other actions as are necessary or appropriate in order to effectuate the actions contemplated by thisSection 2.3 and shall take such other actions reasonably requested by Parent to give effect to the foregoing, without any obligation to pay any consideration or incur any debts or obligations on behalf of the Company or any of its respective Subsidiaries (other than fees and expenses of advisors);provided that such resolutions and actions shall expressly be conditioned upon the consummation of the Merger and the other transactions contemplated hereby and shall be of no force and effect if this Agreement and the Merger Agreement are terminated.

(e) The board of directors of Parent, or a committee of “Non-Employee Directors” thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), in consultation with the Company, shall adopt a resolution before the Closing providing that the receipt by Company Insiders of Parent Common Shares in exchange for Company Common Shares (including Company Converted Restricted Awards) and, as applicable, Company Converted Options, in each case, under the transactions contemplated by this Agreement based on the Section 16 Information provided by the Company to Parent, are intended to be exempt from liability under Section 16(b) under the Exchange Act in accordance with the procedures set forth in Rule 16b-3 promulgated under the Exchange Act and additional guidance issued thereunder.

(f) Following completion of the current offering period ending on December 31, 2012 (and the share purchase relating thereto), notwithstanding anything to the contrary inSection 5.9, (i) subsequent offering periods under the Company’s employee stock purchase plan described inSection 2.3(f) of the Company Disclosure Letter (the “ESPP”) shall be suspended for periods prior to the Effective Time and (ii) prior to the Effective Time, the Company shall provide notice to all participants in the ESPP that the ESPP will be terminated as soon as practicable following the Effective Time. The Company shall take all action necessary to give full effect to thisSection 2.3(f). ESPP Shares shall be treated as Company Common Shares for all purposes of this Agreement. As used in this Agreement, “ESPP Shares” shall mean Company Common Shares purchased under an ESPP.

Section 2.4Treatment of Company Warrants.

applicable authorized and empowered committee thereof) as of the date hereof) (a “Parent Intervening Event”) if such Parent’s board of directors (or applicable authorized and empowered committee thereof) determines in good faith, after consultation with its outside legal counsel, that the failure to take such action would be reasonably likely to violate its fiduciary (or similar) duties under applicable Law. Notwithstanding anything to the contrary contained in this Agreement, (x) no event, development, occurrence, circumstance or fact that affects or relates to Parent or any of its Subsidiaries shall be deemed to be, or contribute to, any Company Intervening Event unless such event, development, occurrence, circumstance or fact also affects or relates to the Company and/or any of its Subsidiaries, and, in such case, the board of directors of the Company (or applicable authorized and empowered committee thereof) shall only consider the extent to which such event, development, occurrence, circumstance or fact affects or relates to the Company and its Subsidiaries (not including any effect on Parent and its Subsidiaries) in determining whether a Recommendation Withdrawal is appropriate in response to such Company Intervening Event, (y) no event, development, occurrence, circumstance or fact that affects or relates to the Company or any of its Subsidiaries shall be deemed to be, or contribute to, any Parent Intervening Event unless such event, development, occurrence, circumstance or fact also affects or relates to Parent and/or any of its Subsidiaries, and, in such case, the board of directors of Parent (or applicable authorized and empowered committee thereof) shall only consider the extent to which such event, development, occurrence, circumstance or fact affects or relates to Parent and its Subsidiaries (not including any effect on the Company and its Subsidiaries) in determining whether a Recommendation Withdrawal is appropriate in response to such Parent Intervening Event and (z) with respect to Parent, no Takeover Proposal shall be deemed to be a Parent Intervening Event unless (1) such Takeover Proposal isbona fide and in writing, (2) such Takeover Proposal has not been obtained in breach ofSection 5.4 and (3) the board of directors of Parent (or applicable authorized and empowered committee thereof) has determined, in the good faith exercise of its fiduciary (or similar) duties, that it shall recommend such Takeover Proposal to its shareholders. For purposes of thisSection 5.4(c), each reference to “10% or more” in the definition of “Takeover Proposal” shall be deemed to be a reference to “more than 50%.” For the avoidance of doubt, no increase in the share price of Parent or Company from the date hereof shall be deemed to be a Parent Intervening Event or Company Intervening Event, respectively,provided that this limitation shall not prevent or otherwise affect a determination that any material event, development, occurrence, or change in circumstances or facts underlying such increase in share price has resulted in a Parent Intervening Event or Company Intervening Event.

(d) Notwithstanding anything to the contrary contained in this Agreement, neither party’s board of directors (nor any authorized and empowered committee thereof) shall be entitled to make a Recommendation Withdrawal underSection 5.4(c), unless (i) such party shall have provided to the other party at least three Business Days before taking such action written notice that it intends to make a Recommendation Withdrawal

and specifying the reasons therefor (and, if applicable, the information required bySection 5.4(f)), (ii) during such three Business Day period, if requested by the other party, the party delivering such written notice shall have engaged in good faith negotiations with the other party regarding any amendment or waiver to this Agreement proposed by the other party which shall be kept confidential by such party (except to the extent required to be disclosed under applicable Law), (iii) such party has not materially breached its obligations under thisSection 5.4 and (iv) solely in the case of a Recommendation Withdrawal by the Company’s board of directors (or an authorized and empowered committee thereof) in response to a Takeover Proposal, the Company’s board of directors (or an authorized and empowered committee thereof) shall have determined, after taking into account all amendments and waivers to this Agreement made in response to such Takeover Proposal, and after consultation with its outside legal counsel and financial advisor, that such Takeover Proposal continues to constitute a Superior Proposal.

Section 5.6Alterra Insurance Company Dividend. Without limiting the generality ofSection 5.3, promptly following the date of this Agreement, the Company shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or

to cause to be done all things necessary, proper or advisable, including the obtaining of all necessary approvals from relevant Governmental Entities, for Alterra Bermuda Limited to declare and pay one or more cash dividends or distributions (collectively, the “Alterra Insurance Company Dividend”) to the Company on or before the Closing Date in the aggregate amount necessary so that on the Closing Date the Company shall have no less than $500,000,000 in immediately available unrestricted funds.

Section 5.7Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, Parent shall and, to the extent applicable, shall cause the Surviving Company to, to the fullest extent permitted by applicable Law (and, in the case of former directors and officers, to the extent permitted by the bye-laws of the Company in effect immediately before the Closing), indemnify, defend and hold harmless, and provide advancement of expenses to, each Person who is now, or has been at any time before the date hereof or who becomes before the Effective Time, a director or officer of the Company or its Subsidiaries (the “Company Indemnified Parties”) from and against all losses, claims, damages, costs, expenses, liabilities, penalties or judgments or amounts that are paid in settlement of or in connection with any claim, action, suit, proceeding or investigation based in whole or in part on or arising in whole or in part out of the fact that such Person is or was a director or officer of the Company or any of its Subsidiaries, and pertaining to any matter existing or occurring, or any acts or omissions occurring, at or before the Effective Time, whether asserted or claimed before, at or following, the Effective Time, including matters, acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby.

(b) Subject toSection 5.7(c), the bye-laws of the Surviving Company shall include provisions for indemnification, advancement of expenses and exculpation of the Company Indemnified Parties at least as favorable as those set forth in the bye-laws of the Company in effect on the date of this Agreement. The parties hereby agree that the form of bye-laws attached hereto as Exhibit C satisfies such requirement. Following the Effective Time, the Surviving Company shall, and Parent shall cause the Surviving Company to, maintain in effect the provisions in its bye-laws providing for indemnification, advancement of expenses and exculpation of the Company Indemnified Parties, as applicable, with respect to the facts or circumstances occurring at or before the Effective Time, to the fullest extent permitted from time to time under applicable Law, which provisions shall not be amended except as required by applicable Law or except to make changes permitted by applicable Law that would enlarge the scope of the Company Indemnified Parties’ indemnification rights thereunder.

(c) Subject to the remaining provisions of thisSection 5.7(c), the Surviving Company shall, and Parent shall cause the Surviving Company to, at no expense to the beneficiaries, either (i) continue to maintain in effect for six years from the Effective Time directors’ and officers’ liability insurance and fiduciary liability insurance having

terms and conditions at least as favorable to the Company Indemnified Parties as the Company’s current directors’ and officers’ liability insurance and fiduciary liability insurance (the “Company Current Insurance”) with respect to matters existing or occurring at or before the Effective Time (including the transactions contemplated hereby), or (ii) purchase a six year extended reporting period endorsement with respect to the Company Current Insurance (a “Company Reporting Tail Endorsement”) and maintain this endorsement in full force and effect for its full term. To the extent purchased after the date hereof and before the Effective Time, such insurance policies shall be placed through such broker(s) and with such insurance carriers as may be specified by the Company and as are reasonably acceptable to Parent. Notwithstanding the foregoing, in no event shall Parent or the Surviving Company be required to expend for any such policies contemplated by thisSection 5.7(c) an annual premium (measured for purposes of any “tail” by reference to 1/6th the aggregate premium paid therefor) amount in excess of 350% of the annual premiums currently paid by the Company for such insurance;provided,further, that if the annual premiums of such insurance coverage exceed such amount, Parent or the Surviving Company shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(d) If Parent or the Surviving Company or any of its successors or assigns (i) consolidates or amalgamates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or amalgamation or (ii) transfers or conveys all or substantially all of its properties and assets to any Person (including by dissolution), then, and in each such case, Parent shall cause proper provision to be made so that the successors and assigns of Parent or the Surviving Company assume and honor the obligations set forth in thisSection 5.7.

(e) From and after the Effective Time, Parent and the Surviving Company agree not to, directly or indirectly, amend, modify, limit or terminate the indemnification, advancement of expenses and exculpation provisions contained in the agreements listed inSection 5.7(e) of the Company Disclosure Letter.

(f) The provisions ofSection 5.7(a) through(e) above: (i) are expressly intended to be for the benefit of, and shall (subject to the second sentence ofSection 5.7(b)) be enforceable by, each Company Indemnified Party, his or her heirs and legal representatives; and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise.

Section 5.8Public Announcements. The press release to be issued after the execution of this Agreement by all parties regarding the Merger shall be a joint press release and thereafter each of Parent and the Company shall, except as may be required by applicable Law or by obligations under any listing agreement with or rules of the NYSE (in the case of Parent) or NASDAQ Global Select Market (in the case of the Company) or by request of any Governmental Entity, give the other party and its Representatives a reasonable opportunity in advance of issuing any press release or

otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby to review and comment on any such press release or public statement (and shall address or include, as applicable, in such press release or public statement comments reasonably proposed by the other party);provided,however, that this consultation obligation shall not apply to any press release or other public statement relating to any actual or contemplated dispute among the parties to this Agreement.

(a) As of the Closing Date, Parent shall, or shall cause one of its Subsidiaries to, continue to employ each Person employed by Parent or the Company or any of their respective Subsidiaries as of the Closing Date (such employees, collectively, the “Employees”). Nothing contained in this Agreement shall (i) restrict Parent in the future in the exercise of its independent, good-faith business judgment as to the terms and conditions under which such employment shall continue, the duration of such employment, the basis on which such employment is terminated or the benefits provided to any Employee or (ii) constitute a guarantee of continued employment of any Employee.

(b) From the Closing Date through December 31, 2013, Parent shall (or shall cause its Subsidiaries to) provide to those Employees who immediately before the Closing were employed by the Company or any of its Subsidiaries such employee benefits and compensation opportunities (including salary, wages and bonus and long-term incentive opportunities) that are the same or substantially comparable in the aggregate to the employee benefits and compensation opportunities in effect for such Employees immediately before the Closing (but excluding any change in control, severance, retention or other pay or benefits with respect to a transaction occurring after the Closing Date);provided, that, the Compensation Committee of the board of directors of Parent may, in its reasonable discretion, (i) implement a transition over at least two years to convert any incentive compensation payment to any such Employee who is an underwriter so that the timing of such payment is consistent with the timing of comparable incentive compensation payments made to those Employees of Parent and its Subsidiaries who are underwriters and (ii) determine that any incentive compensation that would have customarily been granted or paid by the Company in the form of equity may be granted and paid by Parent in cash in lieu of equity.

(c) With respect to any Employee whose employment is terminated by Parent, the Company or any of their respective Subsidiaries from and after the Closing Date and before the first anniversary of the Closing Date, Parent shall provide, or shall cause the Company and its Subsidiaries to provide, severance benefits to such Employee which shall be determined and payable in accordance with the severance benefit plan or agreement set forth onSection 5.9(c) of the Company Disclosure Letter maintained by the Company or any of its Subsidiaries for the benefit of such Employee immediately before the Closing Date, in each case taking into account all service with the Company, Parent and their respective Subsidiaries in determining the amount of severance benefits payable.

(d) Parent and its Subsidiaries shall ensure that any Compensation and Benefit Plan in which the Employees are eligible to participate after the Closing Date shall take into account for purposes of eligibility and vesting thereunder, except for purposes of qualifying for subsidized early retirement benefits (other than under a Company Benefit Plan in effect immediately before the Closing) or to the extent it would result in a duplication of benefits, service by the Employees with the Company and any of its Subsidiaries before the Closing Date, to the same extent such service was credited before the Closing Date under a comparable Compensation and Benefit Plan of the Company.

(e) From and after the Closing Date, Parent shall honor all Company Benefit Plans, in accordance with their terms as in effect immediately before the Closing Date;provided that nothing herein shall limit the right of Parent to amend or terminate any such plan in accordance with its terms.

(f) Notwithstanding the foregoing, nothing herein shall (i) be construed to establish or be treated as an amendment or modification of any Compensation and Benefit Plan, (ii) alter or limit Parent’s or any of its Subsidiaries’ (including the Company and its Subsidiaries, following the Closing) ability to amend, modify or interpret or terminate any Compensation and Benefit Plan at any time in accordance with the terms of such plan and applicable Law or (iii) give any third party, including any Employee, any right to rely upon or demand or enforce the provisions of thisSection 5.9.

Section 5.10Listing; Reservation for Issuance. Parent shall use its reasonable best efforts to cause all the following shares to be approved for listing and quotation on the NYSE, subject to official notice of issuance, no later than the Closing Date: (a) all Parent Common Shares to be issued in the Merger to Company shareholders (including in respect of Company Restricted Awards), and (b) all Parent Common Shares to be reserved for issuance upon exercise or vesting of the Company Converted Warrants, Company Converted Options or Company Converted Restricted Awards (collectively, the “Listed Parent Common Shares”). Parent shall take all action necessary to reserve for issuance, before the Closing Date, any Listed Parent Common Shares that, by their terms and in accordance with this Agreement, will not be issued until after the Effective Time.

Section 5.11Tax Treatment. The parties intend the Merger to be treated for United States federal income Tax purposes as a fully taxable purchase of Company Common Shares by Parent and not qualify as a reorganization within the meaning of Section 368(a) of the Code and to file all U.S. Tax Returns consistent with such treatment.

Section 5.12Notification. The Company shall promptly notify Parent, and Parent shall promptly notify the Company, of (a) any notice or other communication received by such party from any Governmental Entity in connection with the transactions

contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, if the subject matter of such communication or the failure of such party to obtain such consent would reasonably be expected to have a Material Adverse Effect on Company or Parent, as applicable, (b) any matter (including a breach of any representation, warranty, covenant or agreement contained in this Agreement) that would reasonably be expected to lead to the failure to satisfy any of the conditions to the Closing inArticle VI or would trigger a right of termination underSection 7.1 and (c) any action, suit, claim, investigation or proceeding commenced or, to such party’s Knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries that relate to the transactions contemplated hereby. Failure to comply with thisSection 5.12 shall not result in the failure of any condition underArticle VI to be satisfied, unless such condition would have otherwise been satisfied but for such failure to comply with thisSection 5.12.

Section 5.13Obligations of the Merger Sub. Parent shall cause the Merger Sub to perform all of its obligations in connection with this Agreement and the Merger Agreement.

Section 5.14Book Value Calculations.

(a) Within two Business Days following the date of its shareholder meeting held underSection 5.1, unless this Agreement is earlier terminated underSection 7.1 (or such other time as specified inSection 7.2(e)(ii) or Section 7.2(f)(ii)), a party (the “Requesting Party”), may request, by providing notice in writing delivered to the other party (the “Non-Requesting Party”), that the Non-Requesting Party prepare an estimate of the Non-Requesting Party’s Book Value as of the date that is one Business Days before the Requesting Party’s shareholder meeting (such date, the “Measurement Date”, and such estimate of book value, a “Book Value Estimate”). If a Requesting Party makes a request under thisSection 5.14(a), then the Non-Requesting Party shall promptly, and in any event within five days, prepare a Book Value Estimate and provide such Book Value Estimate, together with reasonable supporting analysis, to the Requesting Party.

(b) The Requesting Party shall have five days from and after the time that the Non-Requesting Party delivers its Book Value Estimate to the Requesting Party to review the Non-Requesting Party’s Book Value Estimate and supporting analysis and such other information as the Requesting Party may reasonably request in connection with its review of the Non-Requesting Party’s Book Value Estimate.

(c) (i) If the parties are unable to agree on the Non-Requesting Party’s Book Value within five days following the date that the Non-Requesting Party delivers its Book Value Estimate, and the Requesting Party believes in good faith that the items remaining in dispute would give (or in the case ofSection 7.2(e)(ii) or Section 7.2(f)(ii), would have given) the Requesting Party the right to terminate this Agreement under

Section 7.1(h) orSection 7.1(i) hereof, as applicable, then the Requesting Party shall have the right to refer the determination of such Book Value to an independent accounting firm reasonably acceptable to the Non-Requesting Party (the “Accounting Referee”). The parties shall use their reasonable best efforts to engage the Accounting Referee within two Business Days following the selection of the Accounting Referee.

(ii) If the Non-Requesting Party’s Book Value Estimate is referred to the Accounting Referee, each of Parent and the Company shall within three Business Days following the date of such referral submit to the Accounting Referee its final proposal (with copies thereof simultaneously delivered to the other party) with respect to such disputed Book Value Estimate (which final proposal shall specify any items as to which the parties have been able to agree underSection 5.14(b) and such party’s proposal as to the items in dispute). Parent and the Company shall reasonably cooperate and assist the Accounting Referee in its review of the disputed items and the calculation of Book Value, including giving reasonable access to all relevant information, with due consideration being given to privilege issues and procedures for resolving them. The Accounting Referee shall have the right, upon reasonable notice, to request that the parties make an oral presentation to the Accounting Referee regarding the items in dispute so long as each party shall be afforded a full and equal opportunity to be heard but without unduly prolonging the date by which the Accounting Referee’s determination shall be made in accordance withSection 5.14(d). None of the parties shall disclose to the Accounting Referee, and the Accounting Referee shall not consider for any purpose, any settlement discussions or settlement offer made by any of the parties with respect to any dispute under thisSection 5.14(c), unless otherwise agreed by the parties.

(d) The parties shall use their reasonable best efforts to cause the Accounting Referee to select, within five Business Days of the submission of such final proposals in accordance with the first sentence ofSection 5.14(c)(ii), one of the two final proposals (with no compromise or split decisions being allowed) as being the most representative of the Non-Requesting Party’s Book Value, and the proposal so selected shall be final and binding between the parties. In making such determination, the Accounting Referee shall consider only those items or amounts as to which the parties have been unable to agree underSection 5.14(b), and the proposal of the party so selected by the Accounting Referee shall represent the resolution as to all remaining items or amounts in their entirety. The fees and expenses of the Accounting Referee shall be borne in their entirety by the party whose final proposal is not selected by the Accounting Referee.

Section 8.3Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. If an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. When a reference is made in this Agreement to sections or subsections, such reference shall be to a section or subsection of this Agreement unless otherwise indicated. The phrases “the date of this Agreement”,

“the date hereof” and terms of similar import, will be deemed to refer to December 18, 2012. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “herein,” “hereof,” “hereunder” and words of similar import shall be deemed to refer to this Agreement as a whole, including the Disclosure Letters and the Exhibits hereto, and not to any particular provision of this Agreement. Any pronoun shall include the corresponding masculine, feminine and neuter forms. References to “party” or “parties” in this Agreement mean the Company, the Merger Sub and/or Parent, as the case may be. References to “dollars” or “$” in this Agreement are to the lawful currency of the United States of America. Time periods within or following which any payment is to be made or act is to be done shall be calculated by excluding the day on which the period commences and including the day on which the period ends and by extending the period to the next Business Day following if the last day of the period is not a Business Day. Each section or subsection of a Disclosure Letter qualifies the correspondingly numbered representation, warranty or covenant of the Agreement;provided that information disclosed in one section or subsection of a Disclosure Letter shall be deemed to be included in each other section or subsection of such Disclosure Letter in which the relevance of such information would be readily apparent on the face thereof. Representations and warranties inArticle III that are made in reference to a party’s Disclosure Letter or “in the case of” or “with respect to” a certain party and its Subsidiaries or Affiliates are being made only by that party.

Section 8.4Counterparts. This Agreement may be executed in separate counterparts, each of which shall be considered one and the same agreement and shall become effective when each of the parties has delivered a signed counterpart to the other parties, it being understood that all parties need not sign the same counterpart. Delivery of an executed signature page of this Agreement by facsimile transmission or electronic “.pdf” shall be effective as delivery of a manually executed counterpart hereof.

Section 8.5Entire Agreement; No Third Party Beneficiaries.

(a) This Agreement (including the Exhibits, the Parent Disclosure Letter and the Company Disclosure Letter) constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, other than the Confidentiality Agreement, which shall survive the execution and delivery of this Agreement and shall terminate in accordance with its terms, or if the Closing occurs, as set forth inSection 5.2(b).

(b) This Agreement is not intended to, and shall not, confer upon any other Person any rights or remedies hereunder, except (i) as set forth in or contemplated by the terms and provisions ofSection 5.7, (ii) that, subject toSection 7.3(b), the Company shall have the right to pursue damages (including damages for their loss of economic benefits)

on behalf of the holders of Company Common Shares in the event of any material breach of this Agreement by Parent or Merger Sub (which right is hereby acknowledged by Parent and Merger Sub) and (iii) from and after the Effective Time, the rights of holders of Company Common Shares to receive the Consideration set forth inArticle II.

Section 8.6Governing Law. This Agreement shall be governed by, and construed with regard to, in all respects, including as to validity, interpretation and effect, the Laws of Bermuda, without giving effect to its principles or rules of conflict of laws.

Section 8.7Severability. Any term or provision of this Agreement that is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability and, unless the effect of such invalidity or unenforceability would prevent the parties from realizing a material portion of the economic benefits of the Merger that they currently anticipate obtaining therefrom, shall not render invalid or unenforceable the remaining terms and provisions of this Agreement or affect the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

Section 8.8Assignment. Neither this Agreement nor any of the rights, interests or obligations of the parties hereunder shall be assigned by any of the parties (whether by operation of Law or otherwise) without the prior written consent of the other parties, which may be granted or withheld in the sole discretion of the other parties. Any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns.

Section 8.9Enforcement. The parties agree that money damages would be both incalculable and an insufficient remedy and that irreparable damage would occur if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, subject to the discretion of the Chosen Courts, the parties shall be entitled to an injunction or other equitable relief to prevent breaches or violations of this Agreement and to enforce specifically the terms and provisions of this Agreement in any Chosen Court, this being in addition to any other remedy to which they are entitled at law or in equity. Moreover, and in recognition of the foregoing, each of the parties hereby waives (a) any defense in any action for specific performance of this Agreement that a remedy at law would be adequate and (b) any requirement under any law for any party to post security as a prerequisite to obtaining equitable relief.

Section 8.10Submission to Jurisdiction. Each party irrevocably and unconditionally consents, agrees and submits to the exclusive jurisdiction of the Supreme Court of Bermuda (and appropriate appellate courts therefrom) (the “Chosen Courts”),

for the purposes of any litigation, action, suit or other proceeding with respect to the subject matter hereof. Each party agrees to commence any litigation, action, suit or proceeding relating hereto only in the Supreme Court of Bermuda, or if such litigation, action, suit or other proceeding may not be brought in such court for reasons of subject matter jurisdiction, in the other appellate courts therefrom or other courts of Bermuda. Each party irrevocably and unconditionally waives any objection to the laying of venue of any litigation, action, suit or proceeding with respect to the subject matter hereof in the Chosen Courts, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. Each party further irrevocably and unconditionally consents to and grants any such court jurisdiction over the Person of such parties and, to the extent legally effective, over the subject matter of any such dispute and agrees that mailing of process or other documents in connection with any such action or proceeding in the manner provided inSection 8.2 hereof or in such other manner as may be permitted by applicable Law, shall be valid and sufficient service thereof. The parties agree that a final judgment in any such litigation, action, suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

Section 8.11Amendment. This Agreement may be amended by the parties, by action taken or authorized by their respective boards of directors, at any time before or after receipt of the Required Parent Vote or Required Company Vote;provided that after receipt of any such vote, no amendment shall be made which by Law (or in the case of the Company, the rules and regulations of the NASDAQ Global Select Market or in the case of Parent, the rules and regulations of the NYSE) requires further approval by such shareholders without obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties by their duly authorized representatives.

Section 8.12Extension; Waiver. At any time before the Effective Time, the parties may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other party, (ii) waive any breach of the representations or warranties contained herein or in any document delivered pursuant hereto or (iii) waive compliance with any of the covenants, agreements or conditions contained herein. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. The failure of a party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights. No single or partial exercise of any right, remedy, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. Any waiver shall be effective only in the specific instance and for the specific purpose for which given and shall not constitute a waiver to any subsequent or other exercise of any right, remedy, power or privilege hereunder.

Subject to any special rights conferred on the holders of any share or class of shares, any share in the Company may be issued with or have attached thereto such preferred, deferred, qualified or other special rights or such restrictions, whether in regard to dividend, voting, return of capital or otherwise, as the Company may by Resolution determine or, if there has not been any such determination or so far as the same shall not make specific provision, as the Board may determine.

3.2

Subject to the Companies Acts, any preference shares may, with the sanction of a resolution of the Board, be issued on terms:

3.2.1

that they are to be redeemed on the happening of a specified event or on a given date; and/or,

3.2.2

that they are liable to be redeemed at the option of the Company; and/or,

3.2.3

if authorised by the memorandum of association of the Company, that they are liable to be redeemed at the option of the holder.

The terms and manner of redemption shall be provided for in such resolution of the Board and shall be attached to but shall not form part of these Bye-Laws.

3.3

The Board may, at its discretion and without the sanction of a Resolution, authorise the purchase by the Company of its own shares upon such terms as the Board may in its discretion determine, provided always that such purchase is effected in accordance with the provisions of the Companies Acts.

C-6

3.4

The Board may, at its discretion and without the sanction of a Resolution, authorise the acquisition by the Company of its own shares, to be held as treasury shares, upon such terms as the Board may in its discretion determine, provided always that such acquisition is effected in accordance with the provisions of the Companies Acts. The Company shall be entered in the Register as a Shareholder in respect of the shares held by the Company as treasury shares and shall be a Shareholder of the Company but subject always to the provisions of the Companies Acts and for the avoidance of doubt the Company shall not exercise any rights and shall not enjoy or participate in any of the rights attaching to those shares save as expressly provided for in the Companies Acts.

4	Modification of Rights

4.1

Subject to the Companies Acts, all or any of the special rights for the time being attached to any class of shares for the time being issued may from time to time (whether or not the Company is being wound up) 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 of such shares voting in person or by proxy. To any such separate general meeting, all the provisions of these Bye-Laws as to general meetings of the Company shallmutatis mutandis apply, but so that the necessary quorum shall be one or more persons holding or representing by proxy any of the shares of the relevant class, that every holder of shares of the relevant class shall be entitled on a poll to one vote for every such share held by him and that any holder of shares of the relevant class present in person or by proxy may demand a poll.

4.2

The special rights conferred upon the holders of any shares or class of shares shall not, unless otherwise expressly provided in the rights attaching to or the terms of issue of such shares, be deemed to be altered by the creation or issue of further shares ranking pari passu therewith.

5.1

Subject to the provisions of these Bye-Laws, the unissued shares of the Company (whether forming part of the original capital or any increased capital) shall be at the disposal of the Board, which may offer, allot, grant options over or otherwise dispose of them to such persons, at such times and for such consideration and upon such terms and conditions as the Board may determine.

5.2

Subject to the provisions of these Bye-Laws, any shares of the Company held by the Company as treasury shares shall be at the disposal of the Board, which may hold all or any of the shares, dispose of or transfer all or any of the shares for cash or other consideration, or cancel all or any of the shares.

5.3

The Board may in connection with the issue of any shares exercise all powers of paying commission and brokerage conferred or permitted by law.

C-7

5.4

Except as ordered by a court of competent jurisdiction or as required by law, no person shall be recognised by the Company as holding any share upon trust and the Company shall not be bound by or required in any way to recognise (even when having notice thereof) any equitable, contingent, future or partial interest in any share or in any fractional part of a share or (except only as otherwise provided in these Bye-Laws or by law) any other right in respect of any share except an absolute right to the entirety thereof in the registered holder.

6	Certificates

6.1

The Company shall be under no obligation to complete and deliver a share certificate unless specifically called upon to do so by the person to whom the shares have been issued. In the case of a share held jointly by several persons, delivery of a certificate to one of several joint holders shall be sufficient delivery to all.

6.2

If a share certificate is defaced, lost or destroyed, it may be replaced without fee but on such terms (if any) as to evidence and indemnity and to payment of the costs and out of pocket expenses of the Company in investigating such evidence and preparing such indemnity as the Board may think fit and, in case of defacement, on delivery of the old certificate to the Company.

6.3

All certificates for share or loan capital or other securities of the Company (other than letters of allotment, scrip certificates and other like documents) shall, except to the extent that the terms and conditions for the time being relating thereto otherwise provide, be issued under the Seal or signed by a Director, the Secretary or any person authorised by the Board for that purpose. The Board may by resolution determine, either generally or in any particular case, that any signatures on any such certificates need not be autographic but may be affixed to such certificates by some mechanical means or may be printed thereon or that such certificates need not be signed by any persons.

Lien

7.1

The Company shall have a first and paramount lien on every share (not being a fully paid share) for all monies, whether presently payable or not, called or payable, at a date fixed by or in accordance with the terms of issue of such share in respect of such share, and the Company shall also have a first and paramount lien on every share (other than a fully paid share) standing registered in the name of a Shareholder, whether singly or jointly with any other person, for all the debts and liabilities of such Shareholder or his estate to the Company, whether the same shall have been incurred before or after notice to the Company of any interest of any person other than such Shareholder, and whether the time for the payment or discharge of the same shall have actually arrived or not, and notwithstanding that the same are joint debts or liabilities of such Shareholder or his estate and any other person, whether a Shareholder or not. The Company’s lien on a share shall extend to all dividends payable thereon. The Board may at any time, either generally or in any particular case, waive any lien that has arisen or declare any share to be wholly or in part exempt from the provisions of this Bye-Law.

C-8

7.2

The Company may sell, in such manner as the Board may think fit, any share on which the Company has a lien but no sale shall be made unless some sum in respect of which the lien exists is presently payable nor until the expiration of fourteen (14) days after a notice in writing, stating and demanding payment of the sum presently payable and giving notice of the intention to sell in default of such payment, has been served on the holder for the time being of the share.

7.3

The net proceeds of sale by the Company of any shares on which it has a lien shall be applied in or towards payment or discharge of the debt or liability in respect of which the lien exists so far as the same is presently payable, and any residue shall (subject to a like lien for debts or liabilities not presently payable as existed upon the share prior to the sale) be paid to the person who was the holder of the share immediately before such sale. For giving effect to any such sale, the Board may authorise some person to transfer the share sold to the purchaser thereof. The purchaser shall be registered as the holder of the share and he shall not be bound to see to the application of the purchase money, nor shall his title to the share be affected by any irregularity or invalidity in the proceedings relating to the sale.

8	Calls on Shares

8.1

The Board may from time to time make calls upon the Shareholders (for the avoidance of doubt excluding the Company in respect of any nil or partly paid shares held by the Company as treasury shares) in respect of any monies unpaid on their shares (whether on account of the par value of the shares or by way of premium) and not by the terms of issue thereof made payable at a date fixed by or in accordance with such terms of issue, and each Shareholder shall (subject to the Company serving upon him at least fourteen (14) days notice specifying the time or times and place of payment) pay to the Company at the time or times and place so specified the amount called on his shares. A call may be revoked or postponed as the Board may determine.

8.2

A call may be made payable by instalments and shall be deemed to have been made at the time when the resolution of the Board authorising the call was passed.

8.3

The joint holders of a share shall be jointly and severally liable to pay all calls in respect thereof.

8.4

If a sum called in respect of the share shall not be paid before or on the day appointed for payment thereof the person from whom the sum is due shall pay interest on the sum from the day appointed for the payment thereof to the time of actual payment at such rate as the Board may determine, but the Board shall be at liberty to waive payment of such interest wholly or in part.

C-9

8.5

Any sum which, by the terms of issue of a share, becomes payable on allotment or at any date fixed by or in accordance with such terms of issue, whether on account of the nominal amount of the share or by way of premium, shall for all the purposes of these Bye-Laws be deemed to be a call duly made, notified and payable on the date on which, by the terms of issue, the same becomes payable and, in case of non-payment, all the relevant provisions of these Bye-Laws as to payment of interest, forfeiture or otherwise shall apply as if such sum had become payable by virtue of a call duly made and notified.

8.6

The Board may on the issue of shares differentiate between the allottees or holders as to the amount of calls to be paid and the times of payment.

9	Forfeiture of Shares

9.1

If a Shareholder fails to pay any call or instalment of a call on the day appointed for payment thereof, the Board may at any time thereafter during such time as any part of such call or instalment remains unpaid serve a notice on him requiring payment of so much of the call or instalment as is unpaid, together with any interest which may have accrued.

9.2

The notice shall name a further day (not being less than fourteen (14) days from the date of the notice) on or before which, and the place where, the payment required by the notice is to be made and shall state that, in the event of non-payment on or before the day and at the place appointed, the shares in respect of which such call is made or instalment is payable will be liable to be forfeited. The Board may accept the surrender of any share liable to be forfeited hereunder and, in such case, references in these Bye-Laws to forfeiture shall include surrender.

9.3

If the requirements of any such notice as aforesaid are not complied with, any share in respect of which such notice has been given may at any time thereafter, before payment of all calls or instalments and interest due in respect thereof has been made, be forfeited by a resolution of the Board to that effect. Such forfeiture shall include all dividends declared in respect of the forfeited shares and not actually paid before the forfeiture.

9.4

When any share has been forfeited, notice of the forfeiture shall be served upon the person who was before forfeiture the holder of the share but no forfeiture shall be in any manner invalidated by any omission or neglect to give such notice as aforesaid.

9.5

A forfeited share shall be deemed to be the property of the Company and may be sold, re-offered or otherwise disposed of either to the person who was, before forfeiture, the holder thereof or entitled thereto or to any other person upon such terms and in such manner as the Board shall think fit, and at any time before a sale, re-allotment or disposition the forfeiture may be cancelled on such terms as the Board may think fit.

C-10

9.6

A person whose shares have been forfeited shall thereupon cease to be a Shareholder in respect of the forfeited shares but shall, notwithstanding the forfeiture, remain liable to pay to the Company all monies which at the date of forfeiture were presently payable by him to the Company in respect of the shares with interest thereon at such rate as the Board may determine from the date of forfeiture until payment, and the Company may enforce payment without being under any obligation to make any allowance for the value of the shares forfeited.

9.7

An affidavit in writing that the deponent is a Director of the Company or the Secretary and that a share has been duly forfeited on the date stated in the affidavit shall be conclusive evidence of the facts therein stated as against all persons claiming to be entitled to the share. The Company may receive the consideration (if any) given for the share on the sale, re-allotment or disposition thereof and the Board may authorise some person to transfer the share to the person to whom the same is sold, re-allotted or disposed of, and he shall thereupon be registered as the holder of the share and shall not be bound to see to the application of the purchase money (if any) nor shall his title to the share be affected by any irregularity or invalidity in the proceedings relating to the forfeiture, sale, re-allotment or disposal of the share.

REGISTER OF SHAREHOLDERS

10	Register of Shareholders

The Secretary shall establish and maintain the Register at the Registered Office in the manner prescribed by the Companies Acts. Unless the Board otherwise determines, the Register shall be open to inspection in the manner prescribed by the Companies Acts between 10:00 a.m. and 12:00 noon on every working day. Unless the Board so determines, no Shareholder or intending Shareholder shall be entitled to have entered in the Register any indication of any trust or any equitable, contingent, future or partial interest in any share or any fractional part of a share and if any such entry exists or is permitted by the Board it shall not be deemed to abrogate any of the provisions of Bye-Law 5.4.

REGISTER OF DIRECTORS AND OFFICERS

11	Register of Directors and Officers

The Secretary shall establish and maintain a register of the Directors and Officers of the Company as required by the Companies Acts. The register of Directors and Officers shall be open to inspection in the manner prescribed by the Companies Acts between 10:00 a.m. and 12:00 noon on every working day.

C-11

TRANSFER OF SHARES

12 Transfer of Shares

12.1

Subject to the Companies Acts and to such of the restrictions contained in these Bye-Laws as may be applicable, any Shareholder may transfer all or any of his shares by an instrument of transfer in the usual common form or in any other form which the Board may approve. No such instrument shall be required on the redemption of a share or on the purchase by the Company of a share.

12.2

The instrument of transfer of a share shall be signed by or on behalf of the transferor and where any share is not fully-paid, the transferee. The transferor shall be deemed to remain the holder of the share until the name of the transferee is entered in the Register in respect thereof. All instruments of transfer when registered may be retained by the Company. The Board may, in its absolute discretion and without assigning any reason therefor, decline to register any transfer of any share which is not a fully-paid share. The Board may also decline to register any transfer unless:

12.2.1

the instrument of transfer is duly stamped (if required by law) and lodged with the Company, accompanied by the certificate for the shares to which it relates, and such other evidence as the Board may reasonably require to show the right of the transferor to make the transfer,

12.2.2

the instrument of transfer is in respect of only one class of share, and

12.2.3

where applicable, the permission of the Bermuda Monetary Authority with respect thereto has been obtained.

12.3

Subject to any directions of the Board from time to time in force, the Secretary may exercise the powers and discretions of the Board under this Bye-Law.

12.4

If the Board declines to register a transfer it shall, within three (3) months after the date on which the instrument of transfer was lodged, send to the transferee notice of such refusal.

12.5

No fee shall be charged by the Company for registering any transfer, probate, letters of administration, certificate of death or marriage, power of attorney, stop notice, order of court or other instrument relating to or affecting the title to any share, or otherwise making an entry in the Register relating to any share.

C-12

TRANSMISSION OF SHARES

13 Transmission of Shares

13.1

In the case of the death of a Shareholder, the survivor or survivors, where the deceased was a joint holder, and the estate representative, where he was sole holder, shall be the only person recognised by the Company as having any title to his shares; but nothing herein contained shall release the estate of a deceased holder (whether the sole or joint) from any liability in respect of any share held by him solely or jointly with other persons. For the purpose of this Bye-Law, estate representative means the person to whom probate or letters of administration has or have been granted in Bermuda or, failing any such person, such other person as the Board may in its absolute discretion determine to be the person recognised by the Company for the purpose of this Bye-Law.

13.2

Any person becoming entitled to a share in consequence of the death of a Shareholder or otherwise by operation of applicable law may, subject as hereafter provided and upon such evidence being produced as may from time to time be required by the Board as to his entitlement, either be registered himself as the holder of the share or elect to have some person nominated by him registered as the transferee thereof. If the person so becoming entitled elects to be registered himself, he shall deliver or send to the Company a notice in writing signed by him stating that he so elects. If he shall elect to have his nominee registered, he shall signify his election by signing an instrument of transfer of such share in favour of his nominee. All the limitations, restrictions and provisions of these Bye-Laws relating to the right to transfer and the registration of transfer of shares shall be applicable to any such notice or instrument of transfer as aforesaid as if the death of the Shareholder or other event giving rise to the transmission had not occurred and the notice or instrument of transfer was an instrument of transfer signed by such Shareholder.

13.3

A person becoming entitled to a share in consequence of the death of a Shareholder or otherwise by operation of applicable law shall (upon such evidence being produced as may from time to time be required by the Board as to his entitlement) be entitled to receive and may give a discharge for any dividends or other monies payable in respect of the share, but he shall not be entitled in respect of the share to receive notices of or to attend or vote at general meetings of the Company or, save as aforesaid, to exercise in respect of the share any of the rights or privileges of a Shareholder until he shall have become registered as the holder thereof. The Board may at any time give notice requiring such person to elect either to be registered himself or to transfer the share and, if the notice is not complied with within sixty (60) days, the Board may thereafter withhold payment of all dividends and other monies payable in respect of the shares until the requirements of the notice have been complied with.

C-13

13.4

Subject to any directions of the Board from time to time in force, the Secretary may exercise the powers and discretions of the Board under this Bye-Law.

SHARE CAPITAL

14.1

The Company may from time to time increase its capital by such sum to be divided into shares of such par value as the Company by Resolution shall prescribe.

14.2

The Company may, by the Resolution increasing the capital, direct that the new shares or any of them shall be offered in the first instance either at par or at a premium or (subject to the provisions of the Companies Acts) at a discount to all the holders for the time being of shares of any class or classes in proportion to the number of such shares held by them respectively or make any other provision as to the issue of the new shares.

14.3

The new shares shall be subject to all the provisions of these Bye-Laws with reference to lien, the payment of calls, forfeiture, transfer, transmission and otherwise.

GENERAL MEETINGS AND RESOLUTIONS IN WRITING

17 General Meetings and Resolutions in Writing

17.1

Save and to the extent that the Company elects to dispense with the holding of one or more of its Annual General Meetings in the manner permitted by the Companies Acts, the Board shall convene and the Company shall hold general meetings as Annual General Meetings in accordance with the requirements of the Companies Acts at such times and places as the Board shall appoint. The Board may, whenever it thinks fit, and shall, when required by the Companies Acts, convene general meetings other than Annual General Meetings which shall be called Special General Meetings.

17.2

Except in the case of the removal of Auditors or Directors, anything which may be done by resolution of the Shareholders in general meeting or by resolution of any class of Shareholders in a separate general meeting may be done by resolution in writing, signed by the Shareholders (or the holders of such class of shares) who at the date of the notice of the resolution in writing represent the majority of votes that would be required if the resolution had been voted on at a meeting of the Shareholders. Such resolution in writing may be signed by the Shareholder or its proxy, or in the case of a Shareholder that is a corporation (whether or not a company within the meaning of the Companies Acts) by its representative on behalf of such Shareholder, in as many counterparts as may be necessary.

C-15

17.3

Notice of any resolution in writing to be made under this Bye-Law shall be given to all the Shareholders who would be entitled to attend a meeting and vote on the resolution. The requirement to give notice of any resolution in writing to be made under this Bye-Law to such Shareholders shall be satisfied by giving to those Shareholders a copy of that resolution in writing in the same manner as that required for a notice of a general meeting of the Company at which the resolution could have been considered, except that the length of the period of notice shall not apply. The date of the notice shall be set out in the copy of the resolution in writing.

17.4

The accidental omission to give notice, in accordance with this Bye-Law, of a resolution in writing to, or the non-receipt of such notice by, any person entitled to receive such notice shall not invalidate the passing of the resolution in writing.

17.5

For the purposes of this Bye-Law, the date of the resolution in writing is the date when the resolution in writing is signed by, or on behalf of, the Shareholder who establishes the majority of votes required for the passing of the resolution in writing and any reference in any enactment to the date of passing of a resolution is, in relation to a resolution in writing made in accordance with this Bye-Law, a reference to such date.

17.6

A resolution in writing made in accordance with this Bye-Law is as valid as if it had been passed by the Company in general meeting or, if applicable, by a meeting of the relevant class of Shareholders of the Company, as the case may be. A resolution in writing made in accordance with this Bye-Law shall constitute minutes for the purposes of the Companies Acts and these Bye-Laws.

18 Notice of General Meetings

18.1

An Annual General Meeting shall be called by not less than five (5) days notice in writing and a Special General Meeting shall be called by not less than five (5) days notice in writing.

Notice of every general meeting shall be given in any manner permitted by these Bye-Laws to all Shareholders other than such as, under the provisions of these Bye-Laws or the terms of issue of the shares they hold, are not entitled to receive such notice from the Company and every Director and to any Resident Representative who or which has delivered a written notice upon the Registered Office requiring that such notice be sent to him or it.

Notwithstanding that a meeting of the Company is called by shorter notice than that specified in this Bye-Law, it shall be deemed to have been duly called if it is so agreed:

C-16

18.1.1

in the case of a meeting called as an Annual General Meeting, by all the Shareholders entitled to attend and vote thereat;

18.1.2

in the case of any other meeting, by a majority in number of the Shareholders having the right to attend and vote at the meeting, being a majority together holding not less than ninety-five percent (95%) in nominal value of the shares giving that right.

18.2

The accidental omission to give notice of a meeting or (in cases where instruments of proxy are sent out with the notice) the accidental omission to send such instrument of proxy to, or the non-receipt of notice of a meeting or such instrument of proxy by, any person entitled to receive such notice shall not invalidate the proceedings at that meeting.

18.3

The Board may cancel or postpone a meeting of the Shareholders after it has been convened and notice of such cancellation or postponement shall be served in accordance with these Bye-Laws upon all Shareholders entitled to notice of the meeting so cancelled or postponed setting out, where the meeting is postponed to a specific date, notice of the new meeting in accordance with this Bye-Law.

19 Proceedings at General Meetings

19.1

In accordance with the Companies Acts, a general meeting may be held with only one individual present provided that the requirement for a quorum is satisfied. No business shall be transacted at any general meeting unless a quorum is present when the meeting proceeds to business, but the absence of a quorum shall not preclude the appointment, choice or election of a chairman, which shall not be treated as part of the business of the meeting. Save as otherwise provided by these Bye-Laws, at least one Shareholder present in person or by proxy and entitled to vote shall be a quorum for all purposes.

19.2

If within five (5) minutes (or such longer time as the chairman of the meeting may determine to wait) after the time appointed for the meeting, a quorum is not present, the meeting, if convened on the requisition of Shareholders, shall be dissolved. In any other case, it shall stand adjourned to such other day and such other time and place as the chairman of the meeting may determine and at such adjourned meeting one Shareholder present in person or by proxy and entitled to vote shall be a quorum. The Company shall give not less than five (5) days notice of any meeting adjourned through want of a quorum and such notice shall state that the one Shareholder present in person or by proxy (whatever the number of shares held by them) and entitled to vote shall be a quorum.

19.3

A meeting of the Shareholders or any class thereof may be held by means of such telephone, electronic or other communication facilities (including, without limiting the generality of the foregoing, by telephone, or by video conferencing) as permit all persons participating in the meeting to communicate with each other simultaneously and instantaneously, and participation in such a meeting shall constitute presence in person at such meeting.

C-17

19.4

Each Director, and upon giving the notice referred to in Bye-Law 18.1 above, the Resident Representative, if any, shall be entitled to attend and speak at any general meeting of the Company.

19.5

The Board may choose one of their number to preside as chairman at every general meeting. If there is no such chairman, or if at any meeting the chairman is not present within five (5) minutes after the time appointed for holding the meeting, or is not willing to act as chairman, the Directors present shall choose one of their number to act or if only one Director is present he shall preside as chairman if willing to act. If no Director is present, or if each of the Directors present declines to take the chair, the persons present and entitled to vote on a poll shall elect one of their number to be chairman.

19.6

The chairman of the meeting may, with the consent by resolution of any meeting at which a quorum is present (and shall if so directed by the meeting), adjourn the meeting from time to time and from place to place but no business shall be transacted at any adjourned meeting except business which might lawfully have been transacted at the meeting from which the adjournment took place. When a meeting is adjourned for three (3) months or more, notice of the adjourned meeting shall be given as in the case of an original meeting. Save as expressly provided by these Bye-Laws, it shall not be necessary to give any notice of an adjournment or of the business to be transacted at an adjourned meeting.

20 Voting

20.1

Save where a greater majority is required by the Companies Acts or these Bye-Laws, any question proposed for consideration at any general meeting shall be decided on by a simple majority of votes cast.

20.2

At any general meeting, a resolution put to the vote of the meeting shall be decided on a show of hands or by a count of votes received in the form of electronic records, unless (before or on the declaration of the result of the show of hands or count of votes received as electronic records or on the withdrawal of any other demand for a poll) a poll is demanded by:

20.2.1

the chairman of the meeting; or

20.2.2

at least three (3) Shareholders present in person or represented by proxy; or

20.2.3

any Shareholder or Shareholders present in person or represented by proxy and holding between them not less than one tenth (1/10) of the total voting rights of all the Shareholders having the right to vote at such meeting; or

C-18

20.2.4

a Shareholder or Shareholders present in person or represented by proxy holding shares conferring the right to vote at such meeting, being shares on which an aggregate sum has been paid up equal to not less than one tenth (1/10) of the total sum paid up on all such shares conferring such right.

The demand for a poll may be withdrawn by the person or any of the persons making it at any time prior to the declaration of the result. Unless a poll is so demanded and the demand is not withdrawn, a declaration by the chairman that a resolution has, on a show of hands or count of votes received as electronic records, been carried or carried unanimously or by a particular majority or not carried by a particular majority or lost shall be final and conclusive, and an entry to that effect in the minute book of the Company shall be conclusive evidence of the fact without proof of the number or proportion of votes recorded for or against such resolution.

20.3

If a poll is duly demanded, the result of the poll shall be deemed to be the resolution of the meeting at which the poll is demanded.

20.4

A poll demanded on the election of a chairman, or on a question of adjournment, shall be taken forthwith. A poll demanded on any other question shall be taken in such manner and either forthwith or at such time (being not later than three (3) months after the date of the demand) and place as the chairman shall direct. It shall not be necessary (unless the chairman otherwise directs) for notice to be given of a poll.

20.5

The demand for a poll shall not prevent the continuance of a meeting for the transaction of any business other than the question on which the poll has been demanded and it may be withdrawn at any time before the close of the meeting or the taking of the poll, whichever is the earlier.

20.6

On a poll, votes may be cast either personally or by proxy.

20.7

A person entitled to more than one vote on a poll need not use all his votes or cast all the votes he uses in the same way.

20.8

In the case of an equality of votes at a general meeting, whether on a show of hands or count of votes received as electronic records or on a poll, the chairman of such meeting shall not be entitled to a second or casting vote and the resolution shall fail.

20.9

In the case of joint holders of a share, the vote of the senior who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders, and for this purpose seniority shall be determined by the order in which the names stand in the Register in respect of the joint holding.

C-19

20.10

A Shareholder who is a patient for any purpose of any statute or applicable law relating to mental health or in respect of whom an order has been made by any Court having jurisdiction for the protection or management of the affairs of persons incapable of managing their own affairs may vote, whether on a show of hands or on a poll, by his receiver, committee, curator bonis or other person in the nature of a receiver, committee orcurator bonis appointed by such Court and such receiver, committee,curator bonis or other person may vote on a poll by proxy, and may otherwise act and be treated as such Shareholder for the purpose of general meetings.

20.12

If:

20.12.1

any objection shall be raised to the qualification of any voter; or,

20.12.2

any votes have been counted which ought not to have been counted or which might have been rejected; or,

20.12.3

any votes are not counted which ought to have been counted,

the objection or error shall not vitiate the decision of the meeting or adjourned meeting on any resolution unless the same is raised or pointed out at the meeting or, as the case may be, the adjourned meeting at which the vote objected to is given or tendered or at which the error occurs. Any objection or error shall be referred to the chairman of the meeting and shall only vitiate the decision of the meeting on any resolution if the chairman decides that the same may have affected the decision of the meeting. The decision of the chairman on such matters shall be final and conclusive.

21 Proxies and Corporate Representatives

21.1

The instrument appointing a proxy or corporate representative shall be in writing executed by the appointor or his attorney authorised by him in writing or, if the appointor is a corporation, either under its seal or executed by an officer, attorney or other person authorised to sign the same.

21.2

Any Shareholder may appoint a proxy or (if a corporation) representative for a specific general meeting, and adjournments thereof, or may appoint a standing proxy or (if a corporation) representative, by serving on the Company at the Registered Office, or at such place or places as the Board may otherwise specify for the purpose, a proxy or (if a corporation) an authorisation. Any standing proxy or authorisation shall be valid for all general meetings and adjournments thereof or resolutions in writing, as the case may be, until notice of revocation is received at the Registered Office or at such place or places as the Board may otherwise specify

C-20

for the purpose. Where a standing proxy or authorisation exists, its operation shall be deemed to have been suspended at any general meeting or adjournment thereof at which the Shareholder is present or in respect to which the Shareholder has specially appointed a proxy or representative. The Board may from time to time require such evidence as it shall deem necessary as to the due execution and continuing validity of any standing proxy or authorisation and the operation of any such standing proxy or authorisation shall be deemed to be suspended until such time as the Board determines that it has received the requested evidence or other evidence satisfactory to it.

21.3

Notwithstanding Bye-law 21.2, a Shareholder may appoint a proxy which shall be irrevocable in accordance with its terms and the holder thereof shall be the only person entitled to vote the relevant shares at any meeting of the shareholders at which such holder is present. Notice of the appointment of any such proxy shall be given to the Company at its Registered Office, and shall include the name, address, telephone number and electronic mail address of the proxy holder. The Company shall give to the proxy holder notice of all meetings of Shareholders of the Company and shall be obliged to recognise the holder of such proxy until such time as the holder notifies the Company in writing that the proxy is no longer in force.

21.4

Subject to Bye-Law 21.2 and 21.3, the instrument appointing a proxy or corporate representative together with such other evidence as to its due execution as the Board may from time to time require, shall be delivered at the Registered Office (or at such place as may be specified in the notice convening the meeting or in any notice of any adjournment or, in either case or the case of a resolution in writing, in any document sent therewith) prior to the holding of the relevant meeting or adjourned meeting at which the person named in the instrument proposes to vote or, in the case of a poll taken subsequently to the date of a meeting or adjourned meeting, before the time appointed for the taking of the poll, or, in the case of a resolution in writing, prior to the effective date of the resolution in writing and in default the instrument of proxy or authorisation shall not be treated as valid.

21.5

Subject to Bye-Law 21.2 and 21.3, the decision of the chairman of any general meeting as to the validity of any appointments of a proxy shall be final.

21.6

Instruments of proxy or authorisation shall be in any common form or in such other form as the Board may approve and the Board may, if it thinks fit, send out with the notice of any meeting or any resolution in writing forms of instruments of proxy or authorisation for use at that meeting or in connection with that resolution in writing. The instrument of proxy shall be deemed to confer authority to demand or join in demanding a poll, to speak at the meeting and to vote on any amendment of a resolution in writing or amendment of a resolution put to the meeting for which it is given as the proxy thinks fit. The instrument of proxy or authorisation shall, unless the contrary is stated therein, be valid as well for any adjournment of the meeting as for the meeting to which it relates.

C-21

21.7

A vote given in accordance with the terms of an instrument of proxy or authorisation shall be valid notwithstanding the previous death or unsoundness of mind of the principal, or revocation of the instrument of proxy or of the corporate authority, provided that no intimation in writing of such death, unsoundness of mind or revocation shall have been received by the Company at the Registered Office (or such other place as may be specified for the delivery of instruments of proxy or authorisation in the notice convening the meeting or other documents sent therewith) at least one hour before the commencement of the meeting or adjourned meeting, or the taking of the poll, or the day before the effective date of any resolution in writing at which the instrument of proxy or authorisation is used.

21.8

Subject to the Companies Acts, the Board may at its discretion waive any of the provisions of these Bye-Laws related to proxies or authorisations and, in particular, may accept such verbal or other assurances as it thinks fit as to the right of any person to attend, speak and vote on behalf of any Shareholder at general meetings or to sign resolutions in writing.

22.2

The Company may by Resolution increase the maximum number of Directors. Any one or more vacancies in the Board not filled by the Shareholders at any general meeting of the Shareholders shall be deemed casual vacancies for the purposes of these Bye-Laws. Without prejudice to the power of the Company by Resolution in pursuance of any of the provisions of these Bye-Laws to appoint any person to be a Director, the Board, so long as a quorum of Directors remains in office, shall have power at any time and from time to time to appoint any person to be a Director so as to fill a casual vacancy.

24 Alternate Directors

24.1

A Director may appoint and remove his own Alternate Director. Any appointment or removal of an Alternate Director by a Director shall be effected by delivery of a written notice of appointment or removal to the Secretary at the Registered Office, signed by such Director, and such notice shall be effective immediately upon receipt or on any later date specified in that notice. Any Alternate Director may be removed by resolution of the Board. Subject as aforesaid, the office of Alternate Director shall continue until the next annual election of Directors or, if earlier, the date on which the relevant Director ceases to be a Director. An Alternate Director may also be a Director in his own right and may act as alternate to more than one Director.

24.2

An Alternate Director shall be entitled to receive notices of all meetings of Directors, to attend, be counted in the quorum and vote at any such meeting at which any Director to whom he is alternate is not personally present, and generally to perform all the functions of any Director to whom he is alternate in his absence.

24.3

Every person acting as an Alternate Director shall (except as regards powers to appoint an alternate and remuneration) be subject in all respects to the provisions of these Bye-Laws relating to Directors and shall alone be responsible to the Company for his acts and defaults and shall not be deemed to be the agent of or for any Director for whom he is alternate. An Alternate Director may be paid expenses and shall be entitled to be indemnified by the Company to the same extentmutatis mutandis as if he were a Director. Every person acting as an Alternate Director shall have one vote for each Director for whom he acts as

C-23

alternate (in addition to his own vote if he is also a Director). The signature of an Alternate Director to any resolution in writing of the Board or a committee of the Board shall, unless the terms of his appointment provides to the contrary, be as effective as the signature of the Director or Directors to whom he is alternate.

25 Directors’ Fees and Additional Remuneration and Expenses

The amount, if any, of Directors’ fees shall from time to time be determined by the Company by Resolution or in the absence of such a determination, by the Board. Unless otherwise determined to the contrary, such fees shall be deemed to accrue from day to day. Each Director may be paid his reasonable travel, hotel and incidental expenses in attending and returning from meetings of the Board or committees constituted pursuant to these Bye-Laws or general meetings and shall be paid all expenses properly and reasonably incurred by him in the conduct of the Company’s business or in the discharge of his duties as a Director. Any Director who, by request, goes or resides abroad for any purposes of the Company or who performs services which in the opinion of the Board go beyond the ordinary duties of a Director may be paid such extra remuneration (whether by way of salary, commission, participation in profits or otherwise) as the Board may determine, and such extra remuneration shall be in addition to any remuneration provided for by or pursuant to any other Bye-Law.

26 Directors’ Interests

26.1

A Director may hold any other office or place of profit with the Company (except that of Auditor) in conjunction with his office of Director for such period and upon such terms as the Board may determine, and may be paid such extra remuneration therefor (whether by way of salary, commission, participation in profits or otherwise) as the Board may determine, and such extra remuneration shall be in addition to any remuneration provided for by or pursuant to any other Bye-Law.

26.2

A Director may act by himself or his firm in a professional capacity for the Company (otherwise than as Auditor) and he or his firm shall be entitled to remuneration for professional services as if he were not a Director.

26.3

The Board may also cause the voting power conferred by the shares in any other company held or owned by the Company to be exercised in such manner in all respects as it thinks fit, including the exercise thereof in favour of any resolution appointing the Directors or any of them to be directors or officers of such other company, or voting or providing for the payment of remuneration to the directors or officers of such other company.

C-24

26.4

So long as, where it is necessary, he declares the nature of his interest at the first opportunity at a meeting of the Board or by writing to the Directors as required by the Companies Acts, a Director shall not by reason of his office be accountable to the Company for any benefit which he derives from any office or employment to which these Bye-Laws allow him to be appointed or from any transaction or arrangement in which these Bye-Laws allow him to be interested, and no such transaction or arrangement shall be liable to be avoided on the ground of any interest or benefit.

26.5

Subject to the Companies Acts and any further disclosure required thereby, a general notice to the Directors by a Director or Officer declaring that he is a director or officer or has an interest in a person and is to be regarded as interested in any transaction or arrangement made with that person, shall be a sufficient declaration of interest in relation to any transaction or arrangement so made.

34	Dividends and Other Payments

34.1

The Board may from time to time declare dividends or distributions out of contributed surplus to be paid to the Shareholders according to their rights and interests, including such interim dividends as appear to the Board to be justified by the position of the Company. The Board, in its discretion, may determine that any dividend shall be paid in cash or shall be satisfied, subject to Bye-Law 36, in paying up in full shares in the Company to be issued to the Shareholders credited as fully paid or partly paid or partly in one way and partly the other. The Board may also pay any fixed cash dividend which is payable on any shares of the Company half yearly or on such other dates, whenever the position of the Company, in the opinion of the Board, justifies such payment.

34.2

Except insofar as the rights attaching to, or the terms of issue of, any share otherwise provide:

C-30

34.2.1

all dividends or distributions out of contributed surplus may be declared and paid according to the amounts paid up on the shares in respect of which the dividend or distribution is paid, and an amount paid up on a share in advance of calls may be treated for the purpose of this Bye-Law as paid-up on the share;

34.2.2

dividends or distributions out of contributed surplus may be apportioned and paid pro rata according to the amounts paid-up on the shares during any portion or portions of the period in respect of which the dividend or distribution is paid.

34.3

The Board may deduct from any dividend, distribution or other monies payable to a Shareholder by the Company on or in respect of any shares all sums of money (if any) presently payable by him to the Company on account of calls or otherwise in respect of shares of the Company.

34.4

No dividend, distribution or other monies payable by the Company on or in respect of any share shall bear interest against the Company.

34.5

Any dividend, distribution or interest, or part thereof payable in cash, or any other sum payable in cash to the holder of shares may be paid by cheque or warrant sent through the post or by courier addressed to the holder at his address in the Register or, in the case of joint holders, addressed to the holder whose name stands first in the Register in respect of the shares at his registered address as appearing in the Register or addressed to such person at such address as the holder or joint holders may in writing direct. Every such cheque or warrant shall, unless the holder or joint holders otherwise direct, be made payable to the order of the holder or, in the case of joint holders, to the order of the holder whose name stands first in the Register in respect of such shares, and shall be sent at his or their risk and payment of the cheque or warrant by the bank on which it is drawn shall constitute a good discharge to the Company. Any one of two (2) or more joint holders may give effectual receipts for any dividends, distributions or other monies payable or property distributable in respect of the shares held by such joint holders.

34.6

Any dividend or distribution out of contributed surplus unclaimed for a period of six (6) years from the date of declaration of such dividend or distribution shall be forfeited and shall revert to the Company and the payment by the Board of any unclaimed dividend, distribution, interest or other sum payable on or in respect of the share into a separate account shall not constitute the Company a trustee in respect thereof.

34.7

The Board may also, in addition to its other powers, direct payment or satisfaction of any dividend or distribution out of contributed surplus wholly or in part by the distribution of specific assets, and in particular of paid-up shares or debentures of any other company, and where any difficulty arises in regard to such distribution or dividend, the Board may settle it as it thinks expedient, and in particular, may authorise any person to sell and transfer any fractions or may ignore fractions

C-31

altogether, and may fix the value for distribution or dividend purposes of any such specific assets and may determine that cash payments shall be made to any Shareholders upon the footing of the values so fixed in order to secure equality of distribution and may vest any such specific assets in trustees as may seem expedient to the Board, provided that such dividend or distribution may not be satisfied by the distribution of any partly paid shares or debentures of any company without the sanction of a Resolution.

Reserves

The Board may, before declaring any dividend or distribution out of contributed surplus, set aside such sums as it thinks proper as reserves which shall, at the discretion of the Board, be applicable for any purpose of the Company and pending such application may, also at such discretion, either be employed in the business of the Company or be invested in such investments as the Board may from time to time think fit. The Board may also without placing the same to reserve carry forward any sums which it may think it prudent not to distribute.

CAPITALISATION OF PROFITS

36	Capitalisation of Profits

36.1

The Board may from time to time resolve to capitalise all or any part of any amount for the time being standing to the credit of any reserve or fund which is available for distribution or to the credit of any share premium account and accordingly that such amount be set free for distribution amongst the Shareholders or any class of Shareholders who would be entitled thereto if distributed by way of dividend and in the same proportions, on the footing that the same be not paid in cash but be applied either in or towards paying up amounts for the time being unpaid on any shares in the Company held by such Shareholders respectively or in payment up in full of unissued shares, debentures or other obligations of the Company, to be allotted and distributed credited as fully paid amongst such Shareholders, or partly in one way and partly in the other, provided that for the purpose of this Bye-Law, a share premium account may be applied only in paying up of unissued shares to be issued to such Shareholders credited as fully paid.

36.2

Where any difficulty arises in regard to any distribution under this Bye-Law, the Board may settle the same as it thinks expedient and, in particular, may authorise any person to sell and transfer any fractions or may resolve that the distribution should be as nearly as may be practicable in the correct proportion but not exactly so or may ignore fractions altogether, and may determine that cash payments should be made to any Shareholders in order to adjust the rights of all parties, as may seem expedient to the Board. The Board may appoint any person to sign on behalf of the persons entitled to participate in the distribution any contract necessary or desirable for giving effect thereto and such appointment shall be effective and binding upon the Shareholders.

C-32
