A. CLASS A COMMON SHARES

(1) General. The voting, dividend and liquidation rights of the holders of the Class A Common Shares are subject to and qualified by the rights, powers and preferences of the holders of the Preferred Shares set forth herein.

(2) Voting. The holders of the Class A Common Shares are entitled to notice of and to attend all general meetings of the Company and to one (1) vote for each Class A Common Share held at all general meetings of the Company (including, for greater certainty upon the adoption of resolutions in writing in lieu of a general meeting); provided, however, that, except as otherwise required by law, holders of Class A Common Shares, as such, shall not be entitled to vote on any amendment to the Memorandum of Association or to these Bye-laws that relates solely to the terms of one or more outstanding series of Preferred Shares if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Memorandum of Association, or pursuant to these Bye-laws or pursuant to the Act. There shall be no cumulative voting. The number of authorised Class A Common Shares may be increased or decreased (but not below the number of authorised Class A Common Shares then outstanding) by (in addition to any vote of the holders of one or more series of Preferred Shares that may be required by the terms of the Memorandum of Association or these Bye-laws) the affirmative vote of the holders of the Company’s issued shares representing a majority of the voting power of the issued and outstanding shares entitled to vote.

B. CLASS B COMMON SHARES

(1) General.

B Common Share held at all general meetings of the Company (including, for greater certainty upon the adoption of resolutions in writing in lieu of a general meeting); provided, however, that, except as otherwise required by law, holders of Class B Common Shares, as such, shall not be entitled to vote on any amendment to the Memorandum of Association or to these Bye-laws that relates solely to the terms of one or more outstanding series of Preferred Shares if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Memorandum of Association, or pursuant to these Bye-laws or pursuant to the Act. There shall be no cumulative voting. The number of authorised Class B Common Shares may be increased or decreased (but not below the number of authorised Class B Common Shares then outstanding) by (in addition to any vote of the holders of one or more series of Preferred Shares that may be required by the terms of the Memorandum of Association or these Bye-laws) the affirmative vote of the holders of the Company’s issued shares representing a majority of the voting power of the issued and outstanding shares entitled to vote.

The Company’s Register of Members shall be updated to effect such conversion immediately upon the effectiveness of such Transfer and each outstanding share certificate that, immediately prior to such Transfer, represented one or more Class B Common Shares subject to such Transfer shall, upon and after such Transfer, be deemed to represent an equal number of Class A Common Shares, without the need for surrender or exchange thereof. The Company shall, upon the request of each such holder and upon receipt of such holder’s outstanding certificate, issue and deliver to such holder new certificates representing such holder’s Class A Common Shares. Upon the conversion of any Class B Common Share pursuant to the foregoing provisions, the number of authorised Class B Common Shares shall be diminished by the number of Class B Common Shares that were so converted and the number of Class A Common Shares shall increase in the same amount.

The Company shall issue and deliver at such office to such holder of Class B Common Shares, or to the nominee or nominees or such holder, a certificate or certificates for the number of Class B1 Common Shares to which such holder shall be entitled as aforesaid. Such conversion

shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the Class B Common Shares to be converted and the delivery to the Company of a notice of conversion, and the person or persons entitled to receive the Class B1 Common Shares issuable upon such conversion shall be entered in the Company’s Register of Members as the record holder or holders of and treated for all purposes as the record holder or holders of such Class B1 Common Shares as of such date.

(3) Optional Conversion. Each Class A1 Common Share shall be convertible into one (1) fully paid and non-assessable Class A Common Share at the option of the holder thereof at any time by providing written notice to the Company; provided, however, that the holder of such Class A1 Common Shares shall be prohibited from converting such shares if, immediately prior to or following such conversion (or portion of such conversion thereof) the holder, together with its affiliates and any member of a Section 13(d) group, beneficially owns or would beneficially own as determined in accordance with Section 13(d) of the U.S. Securities Exchange Act of 1934, as amended, and the rules thereunder (the “Exchange Act”) more than 4.99% (the “Beneficial Ownership Limitation”) of the issued and outstanding Class A Common Shares or any other class of equity security (other than an exempted security) that is registered pursuant to Section 12 of the Exchange Act, which Beneficial Ownership Limitation may be increased, decreased or such limitation waived at such holder’s election upon sixty-one (61) days’ written notice to the Company.

The Company shall issue and deliver at such office to such holder of Class A1 Common Shares, or to the nominee or nominees or such holder, a certificate or certificates for the number of Class A Common Shares to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior the close of business on the date of such surrender of the Class A1 Common Shares to be converted and the delivery to the Company of a notice of conversion, and the person or persons entitled to receive the Class A Common Shares issuable upon such conversion shall be entered in the Company’s Register of Members as the record holder or holders of and treated for all purposes as the record holder or holders of such Class A Common Shares as of such date. Upon the conversion of any Class A1 Common Share pursuant to the foregoing provisions, the number of authorised Class A1 Common Shares shall be diminished by the number of Class A1 Common Shares that were so converted and the number of Class A Common Shares shall increase in the same amount. Any purported delivery of any number of Class A Common Shares or any other security upon conversion of Class A1 Common Shares shall be void and have no effect to the extent, but only to the extent, that before or after such delivery, the converting holder of Class A1 Common Shares would have beneficial ownership in excess of the Beneficial Ownership Limitation. All converting holders of Class A1 Common Shares shall disclose to the Company the number of Class A Common Shares or other applicable class of equity securities that it, its affiliates or any member of a Section 13(d) group with such holder owns or has the right to acquire through the exercise or conversion of derivative securities and any limitations on exercise or conversion analogous to the limitation contained herein contemporaneously or immediately prior to submitting a notice of conversion of Class A1 Common Shares to the Company.

The number of authorised Class B1 Common Shares may be increased or decreased (but not below the number of shares thereof then outstanding) by (in addition to any vote of the holders of one or more series of Preferred Shares that may be required by the terms of the Memorandum of Association or these Bye-laws) the affirmative vote of the holders of the Company’s issued shares representing a majority of the voting power of the issued and outstanding shares entitled to vote.

(3) Automatic Conversion. Each Class B1 Common Share shall automatically, without further action by the holder thereof, be converted into and shall become (in such manner as is permitted by Bermuda law) one (1) fully paid and non-assessable Class A Common Share upon the occurrence of a Transfer, other than a Permitted Transfer, of such Class B1 Common Share. The Company’s Register of Members shall be updated to effect such conversion immediately upon the effectiveness of such Transfer and each outstanding share certificate that, immediately prior to such Transfer, represented one or more Class B1 Common Shares subject to such Transfer shall, upon and after such Transfer, be deemed to represent an equal number of Class A Common Shares, without the need for surrender or exchange thereof. The Company shall, upon the request of each such holder and upon receipt of such holder’s outstanding certificate, issue and deliver to such holder new certificates representing such holder’s Class A Common Shares.

The Company shall, as soon as practicable thereafter (and in any event, within three trading days), convert such Class B1 Common Shares by updating its Register of Members and upon such action, to the extent permitted by applicable law, each affected Class B1 Common Share shall be converted into and shall become (in such manner as is permitted by Bermuda law) one (1) fully paid and non-assessable Class A Common Share. The Company shall issue and deliver at such office to such holder of Class B1 Common Shares, or to the nominee or nominees or such holder, a certificate or certificates for the number of Class A Common Shares to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior the close of business on the date of such surrender of the Class B1 Common Shares to be converted and the delivery to the Company of a notice of conversion, and the person or persons entitled to receive the Class A Common Shares issuable upon such conversion shall be entered in the Company’s Register of Members as the record holder or holders of and treated for all purposes as the record holder or holders of such Class A Common Shares as of such date.

Any purported delivery of any number of Class A Common Shares or any other security upon conversion of Class B1 Common Shares shall be void and have no effect to the extent, but only to the extent, that before or after such delivery, the converting holder of Class B1 Common Shares would have beneficial ownership in excess of the Beneficial Ownership Limitation. All converting holders of Class B1 Common Shares shall disclose to the Company the number of Class A Common Shares or other applicable class of equity securities that it, its affiliates or any member of a Section 13(d) group with such holder owns or has the right to acquire through the exercise or conversion of derivative securities and any limitations on exercise or conversion analogous to the limitation contained herein contemporaneously or immediately prior to submitting a notice of conversion of Class B1 Common Shares to the Company.

(4.2) Each Class B1 Common Share shall be convertible into one (1) fully paid and non-assessable Class B Common Share at the option of the holder thereof at any

time by providing written notice to the Company; provided, however, that the holder of such Class B1 Common Shares shall be prohibited from converting such shares if, immediately prior to or following such conversion (or portion of such conversion thereof), the holder, together with its affiliates, and any member of a Section 13(d) group, beneficially owns or would beneficially own as determined in accordance with Section 13(d) of the Exchange Act more than the Beneficial Ownership Limitation of the issued and outstanding Class A Common Shares or any other class of equity security (other than an exempted security) that is registered pursuant to Section 12 of the Exchange Act, which Beneficial Ownership Limitation may be increased, decreased or such limitation waived at such holder’s election upon sixty-one (61) days’ written notice to the Company. Before any holder of Class B1 Common Shares shall be entitled to convert any of such Class B1 Common Shares, such holder shall surrender the certificate or certificates therefor, duly endorsed, at the principal corporate office of the Company or of any transfer agent for the Class B1 Common Shares, and shall give written notice to the Company at its principal corporate office, of the election to convert the same. The Company shall, as soon as practicable thereafter (and in any event, within three trading days), convert such Class B1 Common Shares by updating its Register of Members and upon such action, to the extent permitted by applicable law, each affected Class B1 Common Share shall be converted into and shall become (in such manner as is permitted by Bermuda law) one (1) fully paid and non-assessable Class B Common Share.

Such conversion shall be deemed to have been made immediately prior the close of business on the date of such surrender of the Class B1 Common Shares to be converted and the delivery to the Company of a notice of conversion, and the person or persons entitled to receive the Class B Common Shares issuable upon such conversion shall be entered in the Company’s Register of Members as the record holder or holders of and treated for all purposes as the record holder or holders of such Class B Common Shares as of such date. Upon the conversion of any Class B1 Common Share pursuant to the foregoing provisions, the number of authorised Class B1 Common Shares shall be diminished by the number of Class B1 Common Shares that were so converted and the number of Class B Common Shares shall increase in the same amount. Any purported delivery of any number of Class B Common Shares or any other security upon conversion of Class B1 Common Shares shall be void and have no effect to the extent, but only to the extent, that before or after such delivery, the converting holder of Class B1 Common Shares would have beneficial ownership in excess of the Beneficial Ownership Limitation. All converting holders of Class B1 Common Shares shall disclose to the Company the number of Class A Common Shares or other applicable class of equity securities that it, its affiliates or any member of a Section 13(d) group with such holder owns or has the right to acquire through the exercise or conversion of derivative securities and any limitations on exercise or conversion analogous to the limitation contained herein

contemporaneously or immediately prior to submitting a notice of conversion of Class B1 Common Shares to the Company.

E. PREFERRED SHARES

(1) The Board is authorised to provide for the issuance of the Preferred Shares in one or more series, and to establish from time to time the number of shares to be included in each such series, and to fix the terms, including designation, powers, preferences, rights, qualifications, limitations and restrictions of the shares of each such series (and, for the avoidance of doubt, such matters and the issuance of such Preferred Shares shall not be deemed to vary the rights attached to the Common Shares or, subject to the terms of any other series of Preferred Shares, to vary the rights attached to any other series of Preferred Shares). The authority of the Board with respect to each series shall include, but not be limited to, determination of the following:

(a) the number of shares constituting that series and the distinctive designation of that series;

(b) the dividend rate on the shares of that series, whether dividends shall be cumulative and, if so, from which date or dates, and the relative rights of priority, if any, of the payment of dividends on shares of that series;

(c) whether the series shall have voting rights, in addition to the voting rights provided by law and, if so, the terms of such voting rights;

(d) whether the series shall have conversion or exchange privileges (including, without limitation, conversion into Common Shares) and, if so, the terms and conditions of such conversion or exchange, including provision for adjustment of the conversion or exchange rate in such events as the Board shall determine;

(e) whether or not the shares of that series shall be redeemable or repurchaseable and, if so, the terms and conditions of such redemption or repurchase, including the manner of selecting shares for redemption or repurchase if less than all shares are to be redeemed or repurchased, the date or dates upon or after which they shall be redeemable or repurchaseable, and the amount per share payable in case of redemption or repurchase, which amount may vary under different conditions and at different redemption or repurchase dates;

(f) whether that series shall have a sinking fund for the redemption or repurchase of shares of that series and, if so, the terms and amount of such sinking fund;

(g) the right of the shares of that series to the benefit of conditions and restrictions upon the creation of indebtedness of the Company or any subsidiary, upon the issue of any additional shares (including additional shares of such series or any

other series) and upon the payment of dividends or the making of other distributions on, and the purchase, redemption or other acquisition by the Company or any subsidiary of any issued shares of the Company;

(h) the rights of the shares of that series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Company, and the relative rights of priority, if any, of payment in respect of shares of that series;

(i) the rights of holders of that series to elect or appoint directors; and

(j) any other relative participating, optional or other special rights, qualifications, limitations or restrictions of that series.

(2) Conversion. Any Preferred Shares of any series which have been redeemed (whether through the operation of a sinking fund or otherwise) or which, if convertible or exchangeable, have been converted into or exchanged for shares of any other class or classes shall have the status of authorised and unissued Preferred Shares of the same series and may be reissued as a part of the series of which they were originally a part or may be reclassified and reissued as part of a new series of Preferred Shares to be created by resolution or resolutions of the Board or as part of any other series of Preferred Shares, all subject to the conditions and the restrictions on issuance set forth in the resolution or resolutions adopted by the Board providing for the issue of any series of Preferred Shares.

4.3 At the discretion of the Board, whether or not in connection with the issuance and sale of any shares or other securities of the Company, the Company may issue securities, contracts, warrants or other instruments evidencing any shares, option rights, securities having conversion or option rights, or obligations on such terms, conditions and other provisions as are fixed by the Board including, without limiting the generality of this authority, conditions that preclude or limit any person or persons owning or offering to acquire a specified number or percentage of the issued Common Shares, other shares, option rights, securities having conversion or option rights, or obligations of the Company or transferee of the person or persons from exercising, converting, transferring or receiving the shares, option rights, securities having conversion or option rights, or obligations.

4.4 All the rights attaching to a Treasury Share shall be suspended and shall not be exercised by the Company while it holds such Treasury Share and, except where required by the Act, all Treasury Shares shall be excluded from the calculation of any percentage or fraction of the share capital, or shares, of the Company.

5. Calls on Shares

5.1 The Board may make such calls as it thinks fit upon the Members in respect of any moneys (whether in respect of nominal value or premium) unpaid on the shares allotted to or held by such Members (and not made payable at fixed times by the terms and conditions of issue) 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 Board may differentiate between the holders as to the amount of calls to be paid and the times of payment of such calls.

5.2 Any amount which, by the terms of allotment of a share, becomes payable upon issue or at any fixed date, whether on account of the nominal value of the share or by way of premium, shall for the purposes of these Bye-laws be deemed to be an amount on which a call has been duly made 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, costs and expenses, forfeiture or otherwise shall apply as if such amount had become payable by virtue of a duly made and notified call.

5.3 The joint holders of a share shall be jointly and severally liable to pay all calls and any interest, costs and expenses in respect thereof.

5.4 The Company may accept from any Member the whole or a part of the amount remaining unpaid on any shares held by such Member, although no part of that amount has been called up or become payable.

6. Forfeiture of Shares

6.1 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 the following:

Notice of Liability to Forfeiture for Non-Payment of Call

Kiniksa Pharmaceuticals, Ltd. (the “Company”)

You have failed to pay the call of [amount of call] made on [date], in respect of the [number] share(s) [number in figures] standing in your name in the Register of Members of the Company, on [date], the day appointed for payment of such call. You are hereby notified that unless you pay such call together with interest thereon at the rate of [ ] per

annum computed from the said [date] at the registered office of the Company the share(s) will be liable to be forfeited.

Dated this [date]




[Signature of Secretary] By Order of the Board

6.2 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. Without limiting the generality of the foregoing, the disposal may take place by sale, repurchase, redemption or any other method of disposal permitted by and consistent with these Bye-laws and the Act.

6.3 A Member whose share or shares have been so forfeited 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, together with all interest due thereon and any costs and expenses incurred by the Company in connection therewith.

6.4 The Board may accept the surrender of any shares which it is in a position to forfeit on such terms and conditions as may be agreed. Subject to those terms and conditions, a surrendered share shall be treated as if it had been forfeited.

7. Share Certificates

7.1 Subject to the provisions of this Bye-law 7, every Member shall be entitled to a certificate under the common seal of the Company (or a facsimile thereof) or bearing the signature (or a facsimile thereof) of a Director or the Secretary or a person expressly authorised to sign 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, specifying the amount paid on such shares. 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.

7.2 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 the shares have been allotted.

7.3 If any share 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 it sees fit.

7.4 Notwithstanding any provisions of these Bye-laws:

(a) the Board shall, subject always to the Act and any other applicable laws and regulations and the facilities and requirements of any relevant system concerned, have power to implement any arrangements it may, in its absolute discretion, think fit in relation to the evidencing of title to and transfer of uncertificated shares and to the extent such arrangements are so implemented, no provision of these Bye-laws shall apply or have effect to the extent that it is in any respect inconsistent with the holding or transfer of shares in uncertificated form; and

(b) unless otherwise determined by the Board and as permitted by the Act and any other applicable laws and regulations, no person shall be entitled to receive a certificate in respect of any share for so long as the title to that share is evidenced otherwise than by a certificate and for so long as transfers of that share may be made otherwise than by a written instrument.

8. Fractional Shares

The Company may 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.

REGISTRATION OF SHARES

9. Register of Members

9.1 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.

9.2 The Register of Members shall be open to inspection without charge 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 in accordance with the Act, be closed for any time or times not exceeding in the whole thirty days in each year.

10. Registered Holder Absolute Owner

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 claim or other claim to, or interest in, such share on the part of any other person.

11. Transfer of Registered Shares

11.1 An instrument of transfer shall be in writing in the form of the following, or as near thereto as circumstances admit, or in such other form as the Board may accept:

Transfer of a Share or Shares

Kiniksa Pharmaceuticals, Ltd. (the “Company”)

FOR VALUE RECEIVED [amount], I, [name of transferor] hereby sell, assign and transfer unto [transferee] of [address], [number] shares of the Company.

DATED this [date]

Signed by:		In the presence of:


Transferor		Witness


Signed by:		In the presence of:


Transferee		Witness

11.2 Such instrument of transfer shall be signed by (or in the case of a party that is a corporation, 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 registered as having been transferred to the transferee in the Register of Members.

11.3 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 showing the right of the transferor to make the transfer.

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

11.5 The Board may in its absolute discretion and without assigning any reason therefor refuse to register the transfer of a share which is not fully paid up. The Board shall refuse to register a transfer unless all applicable consents, authorisations and permissions of any governmental body or agency in Bermuda have been obtained. If the Board refuses to register a transfer of any share the Secretary shall, within three months after the date on which the transfer was lodged with the Company, send to the transferor and transferee notice of the refusal.

11.6 Shares may be transferred without a written instrument if transferred by an appointed agent or otherwise in accordance with the Act.

11.7 Notwithstanding anything to the contrary in these Bye-laws, shares that are listed or admitted to trading on an appointed stock exchange may be transferred in accordance with the rules and regulations of such exchange.

12. Transmission of Registered Shares

12.1 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 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.

12.2 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 writing in the form, or as near thereto as circumstances admit, of the following:

Transfer by a Person Becoming Entitled on Death/Bankruptcy of a Member

Kiniksa Pharmaceuticals, Ltd. (the “Company”)

I/We, having become entitled in consequence of the [death/bankruptcy] of [name and address of deceased/bankrupt Member] to [number] share(s) standing in the Register of Members of the Company in the name of the said [name of deceased/bankrupt Member] instead of being registered myself/ourselves, elect to have [name of transferee] (the “Transferee”) registered as a transferee of such share(s) and I/we do hereby accordingly transfer the said share(s) to the Transferee to hold the same unto the Transferee, his or her executors, administrators and assigns, subject to the conditions on which the same were held at the time of the execution hereof; and the Transferee does hereby agree to take the said share(s) subject to the same conditions.

DATED this [date]

Signed by:		In the presence of:


Transferor		Witness


Signed by:		In the presence of:


Transferee		Witness

12.3 On the presentation of the foregoing materials 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. Notwithstanding the foregoing, the Board shall, in any 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, as the case may be.

12.4 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 such 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.

ALTERATION OF SHARE CAPITAL

13. Power to Alter Capital

13.1 The Company may if authorised by resolution of the Members increase, divide, consolidate, subdivide, change the currency denomination of, diminish or otherwise alter or reduce its share capital in any manner permitted by the Act.

13.2 Where, on any alteration or reduction 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.

14. Variation of Rights Attaching to Shares

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 the class at which meeting the necessary quorum shall be two persons at least holding or representing by proxy one-third of the issued shares of the class. The rights conferred upon the holders of the shares of any class or series issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class or series, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith.

DIVIDENDS AND CAPITALISATION

15. Dividends

15.1 The Board may, subject to these Bye-laws and in accordance with 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. No unpaid dividend shall bear interest as against the Company.

15.2 The Board may fix any date as the record date for determining the Members entitled to receive any dividend.

15.3 The Company may 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.

15.4 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. No unpaid distribution shall bear interest as against the Company.

16. Power to Set Aside Profits

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

17. Method of Payment

17.1 Any dividend, interest, or other moneys payable in cash in respect of the shares may be paid by cheque or bank draft sent through the post directed to the Member at such Member’s address in the Register of Members, or to such person and to such address as the Member may direct in writing, or by transfer to such account as the Member may direct in writing.

17.2 In the case of joint holders of shares, any dividend, interest or other moneys payable in cash in respect of shares may be paid by cheque or bank draft sent through the post directed to the address of the holder first named in the Register of Members, or to such person and to such address as the joint holders may direct in writing, or by transfer to such account as the joint holders may direct in writing. 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.

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

17.4 Any dividend and/or other moneys payable in respect of a share which has remained unclaimed for six years from the date when it became due for payment shall, if the Board so resolves, be forfeited and cease to remain owing by the Company. The payment of any unclaimed dividend or other moneys payable in respect of a share may (but need not) be paid by the Company into an account separate from the Company’s own account. Such payment shall not constitute the Company a trustee in respect thereof.

17.5 The Company shall be entitled to cease sending dividend cheques and drafts by post or otherwise to a Member if those instruments have been returned undelivered to, or left uncashed by, that Member on at least two consecutive occasions or, following one such occasion, reasonable enquiries have failed to establish the Member’s new address. The entitlement conferred on the Company by this Bye-law in respect of any Member shall cease if the Member claims a dividend or cashes a dividend cheque or draft.

18. Capitalisation

18.1 The Board may capitalise any 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 amount in paying up unissued shares to be allotted as fully paid bonus shares pro rata (except in connection with the conversion of shares of one class to shares of another class) to the Members.

18.2 The Board may capitalise any amount for the time being standing to the credit of a reserve account or amounts otherwise available for dividend or distribution by applying such amounts in paying up in full, partly or nil paid shares of those Members who would have been entitled to such amounts if they were distributed by way of dividend or distribution.

The Secretary may, and on the instruction of the chairman or president of the Company or the Board, the Secretary shall, postpone or cancel any general meeting called in accordance with these Bye-laws (other than a meeting requisitioned under these Bye-laws) provided that notice of postponement or cancellation is given to the Members before the time for such meeting.

25. Electronic Participation and Security in Meetings

25.1 Members may participate in any general meeting by such telephonic, electronic or other communication facilities or means 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.

25.2 The Board may, and at any general meeting, the chairman of such meeting may, make any arrangement and impose any requirement or restriction it or he considers appropriate to ensure the security of a general meeting including, without limitation, requirements for evidence of identity to be produced by those attending the meeting, the searching of their personal property and the restriction of items that may be taken into the meeting place. The Board and, at any general meeting, the chairman of such meeting are entitled to refuse entry to a person who refuses to comply with any such arrangements, requirements or restrictions.

26. Quorum at General Meetings

26.1 At any general meeting two or more persons present throughout the meeting and representing in person or by proxy a majority of the voting power of the issued and outstanding shares in the Company shall form a quorum for the transaction of business.

26.2 If within half an hour from the time appointed for the meeting a quorum is not present, then, in the case of a meeting convened on a requisition, the meeting shall be deemed cancelled and, in any other case, the meeting shall stand adjourned to the same day one week later, at the same time and place or to such other day, time or place as the Secretary may determine.

In their absence a chairman of the meeting shall be appointed or elected by those present at the meeting and entitled to vote.

28. Voting on Resolutions

28.1 Subject to the Act and these Bye-laws, any question proposed for the consideration of the Members at any general meeting shall be decided by the affirmative votes of a majority of the votes cast in accordance with these Bye-laws and in the case of an equality of votes the resolution shall fail.

28.2 No Member shall be entitled to vote at a general meeting unless such Member has paid all the calls on all shares held by such Member.

(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 amount paid up on all such shares conferring such right.

29.2 Where a poll is demanded, subject to any rights or restrictions for the time being lawfully attached to any class of shares, 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 by ballot as described herein, or in the case of a general meeting at which one or more Members are present by telephone, electronic or other communication facilities or means, 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. A person entitled to more than one vote need not use all his votes or cast all the votes he uses in the same way.

29.3 A poll demanded for the purpose of electing a chairman of the meeting or on a question of adjournment shall be taken forthwith. A poll demanded on any other question shall be taken at such time and in such manner during such meeting as the chairman (or acting chairman) of the meeting may direct. Any business other than that upon which a poll has been demanded may be conducted pending the taking of the poll.

29.4 Where a vote is taken by poll, each person physically present and entitled to vote shall be furnished with a ballot paper on which such person shall record his 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. Each person present by telephone, electronic or other communication facilities or means shall cast his vote in such manner as the chairman of the meeting shall direct. At the conclusion of the poll, the ballot papers and votes cast in accordance with such directions shall be examined and counted by one or more scrutineers appointed by the Board or, in the absence of such appointment, by a committee of not less than two Members or proxy holders appointed by the chairman of the meeting for the purpose, and the result of the poll shall be declared by the chairman of the meeting.

30. Voting by Joint Holders of Shares

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.

company, partnership, unincorporated association or other entity shall be presumed to have control of such entity, in the absence of proof by a preponderance of the evidence to the contrary; provided that notwithstanding the foregoing, such presumption of control shall not apply where such person holds voting shares, in good faith and not for the purpose of circumventing this provision, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group have control of such entity;

(v) “Interested Shareholder” means any person (other than the Company and any entity directly or indirectly wholly-owned or majority-owned by the Company) that (i) is the owner of 15% or more of the issued and outstanding voting shares of the Company, (ii) is an affiliate or associate of the Company and was the owner of 15% or more of the issued and outstanding voting shares of the Company at any time within the three-year period immediately prior to the date on which it is sought to be determined whether such person is an Interested Shareholder or (iii) is an affiliate or associate of any person listed in (i) or (ii) above; provided, however, that the term “Interested Shareholder” shall not include any person whose ownership of shares in excess of the 15% limitation set forth herein is the result of action taken solely by the Company unless such person referred to in this proviso acquires additional voting shares of the Company otherwise than as a result of further corporate action not caused, directly or indirectly, by such person. For the purpose of determining whether a person is an Interested Shareholder, the voting shares of the Company deemed to be issued and outstanding shall include voting shares deemed to be owned by the person through application of paragraph (8) below, but shall not include any other unissued shares which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise;

(vi) “person” means any individual, company, partnership, unincorporated association or other entity;

(vii) “voting shares” means, with respect to any company, shares of any class or series entitled to vote generally in the election of directors, provided that, when used in reference to a vote to approve a merger or amalgamation of the Company which the Act requires to be approved by the Members, such term includes any shares entitled to vote on such matter pursuant to the Act, whether or not they are otherwise entitled to vote and, with respect to any entity that is not a company, any equity interest entitled to vote generally in the election of the governing body

of such entity; and references to percentages of “voting shares” shall be read as references to shares carrying such percentages of votes;

(viii) “owner”, including the terms “own” and “owned”, when used with respect to any shares, means a person that individually or with or through any of its affiliates or associates:

(a) beneficially owns such shares, directly or indirectly; or

(b) has (A) the right to acquire such shares (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise; provided, however, that a person shall not be deemed the owner of shares tendered pursuant to a tender or exchange offer made by such person or any of such person’s affiliates or associates until such tendered shares are accepted for purchase or exchange; or (B) the right to vote such shares pursuant to any agreement, arrangement or understanding; provided, however, that a person shall not be deemed the owner of any shares because of such person’s right to vote such shares if the agreement, arrangement or understanding to vote such shares arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to 10 or more persons; or

(c) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in item (B) of subparagraph (b) of this paragraph), or disposing of such shares with any other person that beneficially owns, or whose affiliates or associates beneficially own, directly or indirectly, such shares.

74.2 In respect of any Business Combination to which the restrictions contained in Bye-law 74.1 do not apply but which the Act requires to be approved by the Members:

(a) where such Business Combination has been approved by the Board, the necessary general meeting quorum and Members’ approval shall be as set out in Bye-laws 26 and 28 respectively; and

(b) where such Business Combination has not been approved by the Board, the necessary Members’ approval shall require the affirmative vote of at least 662/3% of the voting power of the issued and outstanding voting shares of the Company.

74.3 In respect of any merger or amalgamation which is not a Business Combination but which the Act requires to be approved by the Members:

(a) where such merger or amalgamation has been approved by the Board, the necessary general meeting quorum and Members’ approval shall be as set out in Bye-laws 26 and 28 respectively; and

(b) where such merger or amalgamation has not been approved by the Board, the necessary Members’ approval shall require the affirmative vote of at least 66 2/3% of the voting power of the issued and outstanding voting shares of the Company.

74.4 The Board shall ensure that the bye-laws or other constitutional documents of each entity wholly-owned or majority-owned by the Company shall contain any provisions necessary to ensure that the intent of Bye-law 74.1, as it relates to the actions of such entities, is achieved.

VOLUNTARY WINDING-UP AND DISSOLUTION

75. Winding-Up

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 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 the 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.
