(4) 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 by a meeting of the relevant class of Members, as the case may be, and any reference in any Bye-law to a meeting at which a resolution is passed or to Members voting in favour of a resolution shall be construed accordingly.

(5) A resolution in writing made in accordance with this Bye-law shall constitute minutes for the purposes of Sections 81 and 82 of the Act.

(2) No Member shall be entitled to vote at any general meeting unless such Member has paid all the calls on all shares held by such Member.

43. Voting on show of hands

At any general meeting a resolution put to the vote of the meeting shall, in the first instance, be voted upon by a show of hands and, subject to any rights or restrictions for the time being lawfully attached to any class of shares and subject to the provisions of these Bye-laws,

every Member present in person and every person holding a valid proxy at such meeting shall be entitled to one vote and shall cast such vote by raising his or her hand.

44. Decision of chairman

At any general meeting a declaration by the chairman of the meeting that a question proposed for consideration has, on a show of hands, been carried, or carried unanimously, or by a particular majority, or lost, and an entry to that effect in a book containing the minutes of the proceedings of the Company shall, subject to the provisions of these Bye-laws, be conclusive evidence of that fact.

45. Demand for a poll

(1) Notwithstanding the provisions of the immediately preceding two Bye-laws, at any general meeting of the Company, in respect of any question proposed for the consideration of the Members (whether before or on the declaration of the result of a show of hands as provided for in these Bye-laws), a poll may be demanded by any of the following persons:

(a) the chairman of such meeting; or

(b) at least two Members present in person or represented by proxy; or

(c) any Member or Members present in person or represented by proxy and holding between them not less than one-tenth of the total voting rights of all the Members having the right to vote at such meeting; or

(d) any Member or Members present in person or represented by proxy holding shares in the Company 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 of the total sum paid up on all such shares conferring such right.

(2) Where, in accordance with the provisions of paragraph (1) of this Bye-law, a poll is demanded, subject to any rights or restrictions for the time being lawfully attached to any class of shares, including any limitation on the voting power of any Controlled Shares pursuant to Bye-law 50, every Person present at such meeting shall have one vote for each share of which such Person is the holder or for which such person holds a proxy and such vote shall be counted in the manner set out in paragraph (4) of this Bye-law or in the case of a general meeting at which one or more Members are present by telephone in such manner as the chairman of the meeting may direct and the result of such poll shall be deemed to be the resolution of the meeting at which the poll was demanded and shall replace any previous resolution upon the same matter which has been the subject of a show of hands.

(3) A poll demanded in accordance with the provisions of paragraph (1) of this Bye-law, for the purpose of electing a chairman or on a question of adjournment, shall be taken forthwith and a poll demanded on any other question shall be taken in such manner and at such

time and place as the chairman may direct and any business other than that upon which a poll has been demanded may be proceeded with pending the taking of the poll.

(4) Where a vote is taken by poll each person present and entitled to vote shall be furnished with a ballot paper on which such person shall record his or her vote in such manner as shall be determined at the meeting having regard to the nature of the question on which the vote is taken, and each ballot paper shall be signed or initialled or otherwise marked so as to identify the voter and the registered holder in the case of a proxy. At the conclusion of the poll the ballot papers shall be examined and counted by a committee of not less than two Members or proxy holders appointed by the chairman for the purpose and the result of the poll shall be declared by the chairman.

46. Seniority of joint holders voting

In the case of joint holders 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 of Members.

47. Instrument of proxy

The instrument appointing a proxy shall be in writing in the form, or as near thereto as circumstances admit, of Form “A” in the Schedule hereto, under the hand of the appointor or of his attorney duly authorised in writing, or if the appointor is a corporation, either under its seal, or under the hand of a duly authorised officer or attorney. The decision of the chairman of any general meeting as to the validity of any instrument of proxy shall be final.

48. Representation of corporations at meetings

A corporation which is a Member may by written instrument authorise such person as it thinks fit to act as its representative at any meeting of the Members and the person so authorised shall be entitled to exercise the same powers on behalf of the corporation which such person represents as that corporation could exercise if it were an individual Member. Notwithstanding the foregoing, the chairman of the meeting may accept such assurances as he or she thinks fit as to the right of any person to attend and vote at general meetings on behalf of a corporation which is a Member.

SHARE CAPITAL AND SHARES

49. Rights of shares

(1) Subject to any resolution of the Members to the contrary (and without prejudice to any special rights conferred thereby on the holders of any other shares or class of shares), the

share capital of the Company shall be divided into Common Shares, the holders of which shall, subject to the provisions of these Bye-laws:

(a) be entitled to one vote per Common Share or, in the case of Controlled Shares, if applicable, a fraction of a vote per Controlled Share as determined pursuant to Bye-law 50;

(b) be entitled to such dividends as the Board may from time to time declare;

(c) in the event of a liquidation, winding-up or dissolution of the Company, whether voluntary or involuntary or for the purpose of a reorganisation or otherwise or upon any distribution of capital, be entitled to share equally and ratably in the assets of the Company, if any, remaining after the payment of all debts and liabilities of the Company; and

(d) generally be entitled to enjoy all of the rights attaching to shares.

50. Limitation on voting rights of Controlled Shares

(1) Subject to any rights or restrictions for the time being attached to any class or classes of shares, on a poll at a general meeting every Member of record present in person or by proxy shall have one vote for each Common Share registered in his name in the register; provided, however, that, subject to the following provisions of this Bye-law 50, if and for so long as the number of issued Controlled Shares of any Person would constitute more than nine and one half percent (9.5%) of the total combined voting rights attaching to the issued Common Shares of the Company (calculated after giving effect to any prior reduction in voting rights attaching to Common Shares of other Persons as provided in this Bye-law 50), each such issued Controlled Share, regardless of the identity of the registered holder thereof, shall confer only a fraction of a vote as determined by the following formula (the “Formula”):

(T - C) ÷ (9.525 x C)

Where: “T” is the aggregate number of votes conferred by all the issued Common Shares immediately prior to that application of the Formula with respect to such issued Controlled Shares, adjusted to take into account each reduction in such aggregate number of votes that results from a prior reduction in the exercisable votes conferred by any issued Controlled Shares pursuant to Bye-law 50(4) as at the same date; and

“C” is the number of issued Controlled Shares attributable to such Person.

(2) The Directors may, by notice in writing, require any Member to provide, within not less than ten (10) Business Days, complete and accurate information to the registered office or such other place as the Directors may designate in respect of any or all of the following matters:

(a) the number of Common Shares in which such Member is legally or beneficially interested;

(b) the Persons who are beneficially interested in Common Shares in respect of which such Member is the registered holder;

(c) the relationship, association or affiliation of such Member with any other Member or Person whether by means of common control or ownership or otherwise; or

(d) any other facts or matters which the Directors may consider relevant to the determination of the number of Controlled Shares attributable to any Person.

(3) If any Member does not respond to any notice given pursuant to Bye-law 50(2) above within the time specified therein or the Directors shall have reason to believe that any information provided in relation thereto is incomplete or inaccurate, the Directors may determine that the votes attaching to any Common Shares registered in the name of such Member shall be disregarded for all purposes until such time as a response (or additional response) to such notice reasonably satisfactory to the Directors has been received as specified therein.

(4) The Formula shall be applied successively as many times as may be necessary to ensure that no Person shall be a 9.5% Shareholder at any time. For the purposes of determining the votes exercisable by Members as at any date, the Formula shall be applied to the shares of each Member in declining order based on the respective numbers of total Controlled Shares attributable to each Member. Thus, the Formula will be applied first to the votes of shares held by the Member to whom the largest number of total Controlled Shares is attributable and thereafter sequentially with respect to the Member with the next largest number of total Controlled Shares. In each case, calculations are made on the basis of the aggregate number of votes conferred by the issued Common Shares as of such date, as reduced by the application of the Formula to any issued Common Shares of any Member with a larger number of total Controlled Shares as of such date.

(5) If, after giving effect to the provisions of Bye-law 50(1), the votes conferred by the Common Shares directly held by any Related Group would otherwise represent more than 9.5% of the votes conferred by all of the issued and outstanding Common Shares, the votes conferred by such Common Shares are hereby reduced (and shall be automatically reduced in the future) proportionately among all the Common Shares directly held by such Related Group in accordance with the relative voting power of such Common Shares, by whatever amount is necessary so that after any such reduction the votes conferred by the Common Shares directly held by such Related Group shall not exceed 9.5% of the votes conferred by all of the issued and outstanding Common Shares. The amount of any reduction in votes pursuant to this Bye-law 50(5) shall then be allocated and conferred proportionately among the Common Shares held directly by all shareholders or members of the Company who are not in such Related Group in accordance with the relative voting power of such Common Shares, provided, however, that no Common Shares shall be conferred votes to the extent that so doing shall cause any person to be treated as a 9.5% Shareholder.

(6) Notwithstanding the provisions of paragraphs (1) and (2) of this Bye-law 50 above, having applied the provisions thereof as best as they consider reasonably practicable, the Directors may make such final adjustments to the aggregate number of votes attaching to the Common Shares of any Member that they consider fair and reasonable in all the circumstances to ensure that no Person shall be a 9.5% Shareholder at any time.

(7) This Bye-law 50 shall only be effective for and at such times when the Company shall have eleven (11) or more Members holding Common Shares.

51. Power to issue shares

(1) Subject to the restrictions, if any that are provided for in these Bye-laws from time to time and without prejudice to any special rights previously conferred on the holders of any existing shares or class of shares, the Board shall have power to issue any unissued shares of the Company on such terms and conditions as it may determine and any shares or class of shares may be issued with such preferred, deferred or other special rights or such restrictions, whether in regard to dividend, voting, return of capital or otherwise as the Board may determine. Further, the Board may create and issue shares of a new class or of any existing class of shares and the Board may generally exercise the powers of the Company set out in sections 45(1)(b), (c), (d) and (e) of the Act, without the need of any approval of the Members as might otherwise be required by such sections of the Act. The Board may also issue options, warrants or other rights to purchase or acquire shares or, subject to Section 43 of the Act, securities convertible into or exchangeable for shares (including any employee benefit plan providing for the issue of shares or options or rights in respect thereof), at such times, for such consideration and on such terms and conditions as it may determine. The Board may create and issue shares including, but not limited to, series of preferred shares (which may or may not be separate classes of preferred shares), at such times, for such consideration and on such terms and conditions, with similar or different rights or restriction as any other series (or class) and to establish from time to time the number of preferred shares to be included in each such series (or class), and to fix the designation, powers, preferences, voting rights, dividend rights, repurchase provisions, and other rights, qualifications, limitations or restrictions thereof, as it may determine, provided that if any shares so created by the Board confer any voting rights that entitle the holders thereof to vote generally with the Common Shares, such new shares shall also be subject to Bye-law 50 in the same manner as are the Common Shares and shall be included with the Common Shares in determining the limitation on voting rights pursuant to Bye-law 50.

(2) Notwithstanding the foregoing provisions of this Bye-law, the Company shall not issue any shares in a manner that the Board believes would cause, by reason of such issuance, any Person to become or continue to be a 9.5% Shareholder, other than Tower Group, Inc. or any of its Affiliates. Notwithstanding the foregoing provisions of this Bye-law, the restrictions of this Bye-law 51(2) shall not apply to any issuance of shares to a person acting as an underwriter in the ordinary course of its business, purchasing such shares pursuant to a purchase agreement to which the Company is a party, for resale.

(3) The Board shall, in connection with the issue of any share, have the power to pay such commission and brokerage as may be permitted by law.

(4) The Company shall not give, whether directly or indirectly, whether by means of loan, guarantee, provision of security or otherwise, any financial assistance for the purpose of or in connection with a purchase or subscription made or to be made by any person of or for any shares in the Company, but nothing in this Bye-law shall prohibit transactions mentioned in Sections 39A, 39B, and 39C of the Act.

(5) The Company may (and the Board may exercise such power) from time to time do any one or more of the following things:

(a) make arrangements on the issue of shares for a difference between the Members in the amounts and times of payments of calls on their shares;

(b) accept from any Member the whole or a part of the amount remaining unpaid on any shares held by him, although no part of that amount has been called up;

(c) pay dividends in proportion to the amount paid up on each share where a larger amount is paid up on some shares than on others; and

(d) issue its shares in fractional denominations and deal with such fractions to the same extent as its whole shares and shares in fractional denominations shall have in proportion to the respective fractions represented thereby all of the rights of whole shares including (but without limiting the generality of the foregoing) the right to vote, to receive dividends and distributions and to participate in a winding up.

52. Variation of rights and alteration of share capital

(1) If at any time the share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the terms of issue of the shares of that class) may, whether or not the Company is being wound-up, be varied with the consent in writing of the holders of three-fourths of the issued shares of that class or with the sanction of a resolution passed by a majority of the votes cast at a separate general meeting of the holders of the shares of that class in accordance with Section 47(7) of the Act. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith.

(2) The Company may from time to time by resolution of the Members change the currency denomination of, increase, alter or reduce its share capital in accordance with the provisions of Sections 45 and 46 of the Act. Where, on any alteration of share capital, fractions of shares or some other difficulty would arise, the Board may deal with or resolve the same in

such manner as it thinks fit including, without limiting the generality of the foregoing, the issue to Members, as appropriate, of fractions of shares and/or arranging for the sale or transfer of the fractions of shares of Members.

(3) Subject to the restrictions, if any, that are provided for in these Bye-laws from time to time, the Company may from time to time purchase its own shares in accordance with the provisions of Section 42A of the Act.

53. Registered holder of shares

(1) The Company shall be entitled to treat the registered holder of any share as the absolute owner thereof and accordingly shall not be bound to recognise any equitable or other claim to, or interest in, such share on the part of any other person.

(2) Any dividend, interest or other moneys payable in cash in respect of shares may be paid by cheque or draft sent through the post directed to the Member at such Member’s address in the Register of Members or, in the case of joint holders, to such address of the holder first named in the Register of Members, or to such person and to such address as the holder or joint holders may in writing direct. If two or more persons are registered as joint holders of any shares any one can give an effectual receipt for any dividend paid in respect of such shares.

54. Death of a joint holder

Where two or more persons are registered as joint holders of a share or shares then in the event of the death of any joint holder or holders the remaining joint holder or holders shall be absolutely entitled to the said share or shares and the Company shall recognise no claim in respect of the estate of any joint holder except in the case of the last survivor of such joint holders.

55. Share certificates

(1) Every Member shall be entitled to a certificate under the seal of the Company (or a facsimile thereof) specifying the number and, where appropriate, the class of shares held by such Member and whether the same are fully paid up and, if not, how much has been paid thereon. The Board may by resolution determine, either generally or in a particular case, that any or all signatures on certificates may be printed thereon or affixed by mechanical means.

(2) 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 such shares have been allotted.

(3) If any such certificate shall be proved to the satisfaction of the Board to have been worn out, lost, mislaid or destroyed the Board may cause a new certificate to be issued and request an indemnity for the lost certificate if they see fit.

56. Calls on shares

(1) The Board may from time to time make such calls as it thinks fit upon the Members in respect of any monies unpaid on the shares allotted to or held by such Members and, if a call is not paid on or before the day appointed for payment thereof, the Member may at the discretion of the Board be liable to pay the Company interest on the amount of such call at such rate as the Board may determine, from the date when such call was payable up to the actual date of payment. The joint holders of a share shall be jointly and severally liable to pay all calls in respect thereof.

(2) The Board may, on the issue of shares, differentiate between the holders as to the amount of calls to be paid and the times of payment of such calls.

57. Forfeiture of Shares

(1) If any Member fails to pay, on the day appointed for payment thereof, any call in respect of any share allotted to or held by such Member, the Board may, at any time thereafter during such time as the call remains unpaid direct the Secretary to forward such Member a notice in writing in the form, or as near thereto as circumstances admit, of Form “B” in the Schedule hereto.

(2) If the requirements of such notice are not complied with, any such share may at any time thereafter before the payment of such call and the interest due in respect thereof be forfeited by a resolution of the Board to that effect, and such share shall thereupon become the property of the Company and may be disposed of as the Board shall determine.

(3) A Member whose share or shares have been forfeited as aforesaid shall, notwithstanding such forfeiture, be liable to pay to the Company all calls owing on such share or shares at the time of the forfeiture and all interest due thereon.

REGISTER OF MEMBERS

58. Contents of Register of Members

The Board shall cause to be kept in one or more books a Register of Members and shall enter therein the particulars required by the Act.

59. Inspection of Register of Members

The Register of Members shall be open to inspection at the registered office of the Company on every Business Day, subject to such reasonable restrictions as the Board may impose, so that not less than two hours in each business day be allowed for inspection. The Register of Members may, after notice has been given by advertisement in an appointed newspaper to that effect, be closed for any time or times not exceeding in the whole thirty days in each year.

60. Determination of record dates

Notwithstanding any other provision of these Bye-laws, the Board may fix any date as the record date for:

(a) determining the Members entitled to receive any dividend; and

(b) determining the Members entitled to receive notice of and to vote at any general meeting of the Company.

TRANSFER OF SHARES

61. Instrument of transfer

(1) An instrument of transfer shall be in the form or as near thereto as circumstances admit of Form “C” in the Schedule hereto or in such other common form as the Board may accept. Such instrument of transfer shall be signed by or on behalf of the transferor and transferee provided that, in the case of a fully paid share, the Board may accept the instrument signed by or on behalf of the transferor alone. The transferor shall be deemed to remain the holder of such share until the same has been transferred to the transferee in the Register of Members.

(2) The Board may refuse to recognise any instrument of transfer unless it is accompanied by the certificate in respect of the shares to which it relates and by such other evidence as the Board may reasonably require to show the right of the transferor to make the transfer.

62. Restrictions on transfer

(1) Subject to the Act, this Bye-law 62 and such other of the restrictions contained in these Bye-laws and elsewhere as may be applicable, and except, in the case of any shares other than the Common Shares, as may otherwise be provided by the terms of issuance thereof, any Member may sell, assign, transfer or otherwise dispose of shares of the Company at the time owned by it and, upon receipt of a duly executed form of transfer in writing, the Directors shall procure the timely registration of the same. If the Directors refuse to register a transfer for any reason they shall notify the proposed transferor and transferee within thirty days of such refusal.

(2) Except for shares held by Tower Group, Inc. or any of its Affiliates, the Directors shall decline to register a transfer of shares if the Directors have reason to believe that the effect of such transfer would be that any Person would become or continue to be a 9.5% Shareholder or a United States 25% Shareholder.

(3) The Directors may, in their absolute and unfettered discretion, decline to register the transfer of any shares if the Directors have reason to believe (i) that such transfer may expose the Company, any subsidiary thereof, any Member or any Person ceding insurance to the Company or any such subsidiary to adverse tax or regulatory treatment in any jurisdiction or (ii) that registration of such transfer under the Securities Act or under any blue sky or other U.S. state securities laws or under the laws of any other jurisdiction is required and such registration has not been duly effected (provided, however, that in this case (ii) the Directors shall be entitled to request and rely on an opinion of counsel to the transferor or the transferee, in form and substance satisfactory to the Directors, that no such approval or consent is required and no such violation would occur, and the Directors shall not be obligated to register any transfer absent the receipt of such an opinion).

(4) Without limiting the foregoing, the Board shall decline to approve or register a transfer of shares unless all applicable consents, authorisations, permissions or approvals of any governmental body or agency in Bermuda, the United States or any other applicable jurisdiction required to be obtained prior to such transfer shall have been obtained.

(5) The registration of transfers may be suspended at such time and for such periods as the Directors may from time to time determine; provided that such registration shall not be suspended for more than forty-five days in any period of three hundred and sixty five (365) consecutive days.

(6) The Directors may require any Member, or any Person proposing to acquire shares of the Company, to certify or otherwise provide information in writing as to such matters as the Directors may request for the purpose of giving effect to Bye-laws 10(2), 51(2), 62(2) and 62(3), including as to such Person’s status as a U.S. Person, its Controlled Shares and other matters of the kind contemplated by Bye-law 50(2). Such request shall be made by written notice

and the certification or other information requested shall be provided to such place and within such period (not less than ten (10) Business Days after such notice is given unless the Directors and such Member or proposed acquiror otherwise agree) as the Directors may designate in such request. If any Member or proposed acquiror does not respond to any such request by the Directors as requested, or if the Directors have reason to believe that any certification or other information provided pursuant to any such request is inaccurate or incomplete, the Directors may decline to register any transfer or to effect any issuance or purchase of shares to which such request relates.

(7) The restrictions on transfer authorized by this Bye-law 62 shall not be imposed in any circumstance in a way that would interfere with the settlement of trades or transactions in the Common Shares entered into through the facilities of the PORTAL market; provided, however, that the Company may decline to register transfers in accordance with these Bye-laws or resolutions of the Board after a settlement has taken place.

63. Transfers by joint holders

The joint holders of any share or shares may transfer such share or shares to one or more of such joint holders, and the surviving holder or holders of any share or shares previously held by them jointly with a deceased Member may transfer any such share or shares to the executors or administrators of such deceased Member.

64. Lien on Shares

(1) The Company shall have a first and paramount lien and charge on all shares (whether fully paid-up or not) registered in the name of a Member (whether solely or jointly with others) for all debts, liabilities or engagements to or with the Company (whether presently payable or not) by such Member or his estate, either alone or jointly with any other Person, whether a Member or not, but the Directors may at any time declare any share to be wholly or in part exempt from the provisions of this Bye-law. The registration of a transfer of any such share shall operate as a waiver of the Company’s lien (if any) thereon. The Company’s lien (if any) on a share shall extend to all dividends or other monies payable in respect thereof.

(2) The Company may sell, in such manner as the Directors think fit, any shares on which the Company has a lien, but no sale shall be made unless a sum in respect of which the lien exists is then presently payable, nor until the expiration of fourteen days after a notice in writing stating and demanding payment of such part of the amount in respect of which the lien exists as is presently payable, has been given to the relevant Member, or the Person, of which the Company has notice, entitled thereto by reason of such Member’s death or bankruptcy. Effective upon such sale, any certificate representing such shares prior to such sale shall become null and void, whether or not it was actually delivered to the Company.

(3) To give effect to any such sale the Directors may authorise some Person to transfer the shares sold to the purchaser thereof. The purchaser shall be registered as the holder of the shares comprised in any such transfer, and he shall not be bound to see to the application of the purchase money, nor shall his title to the shares be affected by any irregularity or invalidity in the proceedings in reference to the sale.

(4) The proceeds of such sale shall be received by the Company and applied in payment of such part of the amount in respect of which the lien exists as is presently payable and the residue, if any, shall (subject to a like lien for sums not presently payable as existed upon the shares before the sale) be paid to the Person entitled to the shares immediately prior to such sale.

TRANSMISSION OF SHARES

65. Registration on death or bankruptcy

Any Person becoming entitled to a share in consequence of the death or bankruptcy of any Member may be registered as a Member upon such evidence as the Board may deem sufficient or may elect to nominate some Person to be registered as a transferee of such share, and in such case the Person becoming entitled shall execute in favour of such nominee an instrument of transfer in the form, or as near thereto as circumstances admit, of Form “D” in the Schedule hereto. On the presentation thereof to the Board, accompanied by such evidence as the Board may require to prove the title of the transferor, the transferee shall be registered as a Member but the Board shall, in either case, have the same right to decline or suspend registration as it would have had in the case of a transfer of the share by that Member before such Member’s death or bankruptcy.

66. Representative of deceased Member

In the case of the death of a Member, the survivor or survivors where the deceased Member was a joint holder, and the legal personal representatives of the deceased Member where the deceased Member was a sole holder, shall be the only Persons recognised by the Company as having any title to the deceased Member’s interest in the shares. Nothing herein contained shall release the estate of a deceased joint holder from any liability in respect of any share which had been jointly held by such deceased Member with other Persons. Subject to the provisions of Section 52 of the Act, for the purpose of this Bye-law, legal personal representative means the executor or administrator of a deceased Member or such other Person as the Board may in its absolute discretion decide as being properly authorised to deal with the shares of a deceased Member.

DIVIDENDS AND OTHER DISTRIBUTIONS

67. Declaration of dividends by the Board

Subject to any rights or restrictions at the time lawfully attached to any class of shares and subject to these Bye-laws, the Board may, in accordance with Section 54 of the Act, declare a dividend to be paid to the Members, in proportion to the number of shares held by them, and such dividend may be paid in cash or wholly or partly in specie in which case the Board may fix the value for distribution in specie of any assets.

68. Other distributions

The Board may declare and make such other distributions (in cash or in specie) to the Members as may be lawfully made out of the assets of the Company.

69. Reserve fund

The Board may from time to time before declaring a dividend set aside, out of the surplus or profits of the Company, such sum as it thinks proper as a reserve fund to be used to meet contingencies or for equalising dividends or for any other special purpose.

70. Deduction of amounts due to the Company

The Board may deduct from the dividends or distributions payable to any Member all monies due from such Member to the Company on account of calls or otherwise.

71. Unclaimed dividends

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

72. Interest on dividend

No dividend or distribution shall bear interest against the Company.

73. Issue of bonus shares

(1) Subject to Bye-law 51(2), the Board may resolve to capitalise any part of the amount for the time being standing to the credit of any of the Company’s share premium or other reserve accounts or to the credit of the profit and loss account or otherwise available for distribution by applying such sum in paying up unissued shares to be allotted as fully paid bonus shares pro rata to the Members.

(2) The Company may capitalise any sum standing to the credit of a reserve account or sums otherwise available for dividend or distribution by applying such amounts in paying up in full partly paid shares of those Members who would have been entitled to such sums if they were distributed by way of dividend or distribution.

ACCOUNTS AND FINANCIAL STATEMENTS

(c) the assets and liabilities of the Company.

Subject to Section 88 of the Act, at the annual general meeting or at a subsequent special general meeting in each year, an independent representative of the Members shall be appointed by them as Auditor of the accounts of the Company. Such Auditor may be a Member but no

Director, Officer or employee of the Company shall, during his or her continuance in office, be eligible to act as an Auditor of the Company.

78. Remuneration of Auditor

The remuneration of the Auditor shall be fixed by the Company in general meeting or in such manner as the Members may determine, or, by the Board as permitted under the Act.

79. Vacation of office of Auditor

If the office of Auditor becomes vacant by the resignation or death of the Auditor, or by the Auditor becoming incapable of acting by reason of illness or other disability at a time when the Auditor’s services are required, the Board shall, as soon as practicable, convene a special general meeting to fill the vacancy thereby created.

80. Access to books of the Company

NOTICES

82. Notices to Members of the Company

A notice may be given by the Company to any Member either by delivering it to such Member in person or by sending it to such Member’s address in the Register of Members or to

such other address given in writing for the purpose. For the purposes of this Bye-law, a notice may be sent by mail, courier service, cable, telex, telecopier, facsimile or other mode of representing words in a legible and non-transitory form.

83. Notices to joint Members

Any notice required to be given to a Member shall, with respect to any shares held jointly by two or more persons, be given to whichever of such persons is named first in the Register of Members and notice so given shall be sufficient notice to all the holders of such shares.

84. Service and delivery of notice

Any notice shall be deemed to have been served at the time when the same would be delivered in the ordinary course of transmission and, in proving such service, it shall be sufficient to prove that the notice was properly addressed and prepaid, if posted, and the time when it was posted, delivered to the courier or to the cable company or transmitted by telex, facsimile or other method as the case may be.

85. The Seal

The seal of the Company shall be in such form as the Board may from time to time determine. The Board may adopt one or more duplicate seals for use outside Bermuda.

WINDING-UP

87. Winding-up/distribution by liquidator

Subject to the Act, the Company may be wound up voluntarily by resolution of the Members. If the Company shall be wound up the liquidator may, with the sanction of a resolution of the Members, divide amongst the Members in specie or in kind the whole or any part of the assets of the Company (whether they shall consist of property of the same kind or not) and may, for such purpose, set such value as he or she deems fair upon any property to be divided as aforesaid and may determine how such division shall be carried out as between the

Members or different classes of Members. The liquidator may, with the like sanction, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the Members as the liquidator shall think fit, but so that no Member shall be compelled to accept any shares or other securities or assets whereon there is any liability.

ALTERATION OF BYE-LAWS

88. Alteration of Bye-laws

No Bye-law shall be rescinded, altered or amended and no new Bye-law shall be made until the same has been approved by a resolution of the Board and by a resolution of the Members, in accordance with Bye-law 42.
