Constitution 2A. "A" Class Shares I Allens Arthur Robinson_1 _ Shares bearing the consecutive numbers 10,001 to 15,010,000 shall be known as "A" Class Shares but otherwise than for such designation the same shall have and be deemed to have all the rights of ordinary shares. 3. Board's power to issue shares Except as provided by contract or this Constitution to the contrary, all unissued shares are under the control of the Board which may grant options on the shares, issue or otherwise dispose of the shares on the terms and conditions and for the consideration it thinks fit. An issue of shares of the same class as an existing class of shares is not to be considered to constitute a variation of the rights of the holders of shares in the existing class. Any Director or any person who is an associate of a Director may participate in any issue by the Company of securities. 4. Surrender of shares In its discretion, the Board may accept a surrender of shares by way of compromise of any question as to whether or not those shares have been validly issued or in any other case where the surrender is within the powers of the Company. Any shares surrendered may be sold or re-issued in the same manner as forfeited shares. 5. Joint holders Where two or more persons are registered as the holders of any shares, they are considered to hold the shares as joint tenants with benefits of survivorship subject to the following provisions: (a) Number of holders the Company is not bound to register more than three persons as the holders of the shares (except in the case of personal representatives of a deceased shareholder); (b) Liability for payments the joint holders of the shares are liable severally as well as jointly in respect of all payments which ought to be made in respect of the shares; (c) Death of joint holder on the death of any one of the joint holders, the survivor is the only person recognised by the Company as having any title to the shares but the Board may require evidence of death and the estate of the deceased joint holder is not released from any liability in respect of the shares; (d) Power to give receipt any one of the joint holders may give a receipt for any dividend, bonus or return of capital payable to the joint holders; ljhp P0110103481v1 60-4955093 Page 3

Constitution I Allens Arthur Robinson_!'_ (e) Notices and certificates only the person whose name stands first in the Register as one of the joint holders of the shares is entitled, if the Company determines to issue certificates for shares, to delivery of a certificate relating to the shares or to receive notices from the Company and any notice given to that person is considered to be notice to all the joint holders; and (f) Votes of joint holders any one of the joint holders may vote at any meeting of the Company either personally or by duly authorised representative, proxy or attorney, in respect of the shares as if that joint holder was solely entitled to the shares. If more than one of the joint holders are present personally or by duly authorised representative, proxy or attorney, only the vote of the joint holder whose name appears first in the Register counts. 6. Non-recognition of equitable or other interests Except as otherwise provided in this Constitution, or as required by law, the Company is entitled to treat the registered holder of any share as the absolute owner of the share and is not bound to recognise (even when having notice) any equitable or other claim to or interest in the share on the part of any other person. Certificates 7. Certificates Calls The Board may determine to issue certificates for shares or other securities of the Company, to cancel any certificates on issue, to replace lost, destroyed or defaced certificates on issue on the basis and in the form it thinks fit from time to time. 8. Power to make calls Subject to the terms on which any shares may have been issued, the Board may make calls on the shareholders in respect of money unpaid on their shares. Each shareholder is liable to pay the amount of each call in the manner, at the time and at the place specified by the Board. Calls may be made payable by instalments. 9. Obligation for calls The Company may make arrangements on the issue of shares for a difference between the holders of those shares in the amount of calls to be paid and the time of payment of the calls. ljhp P0110103481v1 60-4955093 Page4

Constitution 10. When a call is made I Allens Arthur Robinson-,- A call is taken to have been made at the time when the resolution of the Board authorising the call was passed. The call may be revoked or postponed at the discretion of the Board at any time prior to the date on which payment in respect of the call is due. The non­ receipt of a notice of any call by, or the accidental omission to give notice of any call to, any shareholder, does not invalidate the call. 11. Interest on the late payment of calls If any sum payable in respect of a call is not paid on or before the date for payment, the shareholder from whom the sum is due is to pay interest on the unpaid amount from the due date to the date of payment at the rate the Board determines. The Board may waive the whole or part of any interest paid or payable under this Rule. 12. Instalments If, by the terms of an issue of shares, any amount is payable in respect of any shares by instalments, every instalment is payable as if it is a call duly made by the Board of which due notice had been given, and all provisions of this Constitution with respect to the payment of calls and of interest or to the forfeiture of shares for non-payment of calls or with respect to liens or charges apply to the instalment and to the shares in respect of which it is payable. Forfeiture and Lien 13. Notice requiring payment of sums payable If any shareholder fails to pay any sum payable in respect of any shares, either for issue money, calls or instalments, on or before the day for payment, the Board may serve a notice on the shareholder requiring that shareholder to pay the sum together with interest accrued and all expenses incurred by the Company by reason of the non-payment. The notice may be served at any time whilst any part of the sum remains unpaid. 14. Time and place for payment The notice referred to in Rule 13 is to name a day on or before which the sum, interest and expenses (if any) are to be paid and the place where payment is to be made and that, if payment is not made by the time and at the place specified, the shares in respect of which the sum is payable are liable to be forfeited. 15. Forfeiture on non-compliance with notice If there is non-compliance with the requirements of any notice given under Rule 13, any shares in respect of which notice has been given may be forfeited by a resolution of the Board passed at any time after the day specified in the notice for payment. The forfeiture ljhp P0110103481v1 60-4955093 Page 5

Constitution I Allens Arthur Robinson _1 _ is to include all dividends, interest and other money payable by the Company in respect of the forfeited shares and not actually paid before the forfeiture. 16. Notice of forfeiture When any share is forfeited, notice of the resolution of the Board must be given to the shareholder in whose name the share was registered immediately prior to the forfeiture, and an entry of the forfeiture and the date of forfeiture must be made in the Register. Failure to give notice or make the entry as required by this Rule does not invalidate the forfeiture. 17. Disposal of forfeited shares Any forfeited share is considered to be the property of the Company and the Board may sell or otherwise dispose of or deal with the share in any manner it thinks fit and with or without any money paid on the share by any former holder being credited as paid up. 18. Annulment of forfeiture At any time before any forfeited share is sold or otherwise disposed of, the Board may annul the forfeiture of the share on any condition it thinks fit. 19. Liability despite forfeiture ·Any shareholder whose shares have been forfeited is, despite the forfeiture, liable to pay and must immediately pay to the Company all sums of money, interest and expenses owing on or in respect of the forfeited shares at the time of forfeiture, together with expenses and interest from that time until payment at the rate the Board determines. The Board may enforce the payment or waive the whole or part of any sum paid or payable under this Rule as it thinks fit. 20. Company's lien or charge The Company has a first and paramount lien or charge for unpaid calls, instalments, interest due in relation to any calls or instalments and any amounts the Company is called on by law to pay in respect of the shares of a shareholder on shares registered in the name of the shareholder in respect of which the calls, instalments and interest are due and unpaid (whether then payable or not) or in respect of which the amounts are paid and on the proceeds of sale of the shares. The lien or charge extends to all dividends and bonuses declared in respect of the shares but, if the Company registers a transfer of any shares on which it has a lien or charge without giving the transferee notice of any claim it may have at that time, the shares are freed and discharged from the lien or charge of the Company in respect of that claim. ljhp P0110103481v1 60-4955093 Page 6

_I_ Constitution Allens Arthur Robinson 1 21. Sale of shares to enforce lien For the purpose of enforcing a lien or charge, the Board may sell the shares which are subject to the lien or charge in any manner it thinks fit and with or without giving any notice to the shareholder in whose name the shares are registered. 22. Title to shares forfeited or sold to enforce lien (a) • In a sale or a re-issue of forfeited shares or in the sale of shares to enforce a lien or charge, an entry in the Board's minute book that the shares have been forfeited, sold or re-allotted in accordance with this Constitution is sufficient evidence of that fact as against all persons entitled to the shares immediately before the forfeiture, sale or re-issue of the shares. The Company may receive the purchase money or consideration (if any) given for the shares on any sale or re-issue. (b) In a re-issue, a certificate signed by a Director or the Secretary to the effect that the shares have been forfeited and the receipt of the Company for the price of the shares constitutes a good title to them. (c) In a sale, the Company may appoint a person to execute a transfer in favour of the person to whom the shares are sold. (d) On the issue of the receipt or the execution of the transfer the person to whom the shares have been re-allotted or sold is to be registered as the holder of the shares, discharged from all calls or other money due in respect of the shares prior to the re-issue or purchase and the person is not bound to see to the regularity of the proceedings or to the application of the purchase money or consideration and the person's title to the shares is not affected by any irregularity or invalidity in the proceedings relating to the forfeiture, sale or re-issue. (e) The net proceeds of any sale or re-issue are to be applied first in payment of all costs in relation to the enforcement of the lien or charge or the forfeiture and of the sale or re-issue, next in satisfaction of the amount in respect of which the lien or charge exists as is then payable to the Company (including interest) or the amount in respect of the forfeited shares then payable to the Company (including interest) and the residue (if any) paid to, or at the direction of, the person registered as the holder of the shares immediately prior to the sale or re-issue or to the person's executors, administrators or assigns on the production of any evidence as to title required by the Board. Payments by the Company 23. Payments by the Company If any law of any place imposes or purports to impose any immediate or future or possible liability on the Company to make any payment, or empowers any government or taxing authority or government official to require the Company to make any payment, in respect of any securities held either jointly or solely by any holder or in respect of any transfer of ljhp P0110103481v1 60-4955093 Page 7

Constitution I Allens Arthur Robinson-,- those securities or in respect of any interest, dividends, bonuses or other money due or payable or accruing due or which may become due or payable to the holder by the Company on or in respect of any securities or for or on account or in respect of any holder of securities, whether because of: (a) the death of the holder; (b) the non-payment of any income tax or other tax by the holder; (c) the non-payment of any estate, probate, succession, death, stamp or other duty by the holder or personal representative of that holder or by or out of the holder's estate; (d) any assessment of income tax against the Company in respect of interest or dividends paid or payable to the holder; or (e) any other act or thing, the Company in each case: (i) is to be fully indemnified from all liability by the holder or the holder's personal representative and by any person who becomes registered as the holder of the securities on the distribution of the deceased holder's estate; (ii) has a lien or charge on the securities for all money paid by the Company in respect of the securities because of any law; (iii) has a lien on all dividends, bonuses and other money payable in respect of the securities registered in the Register as held either jointly or solely by the holder for all money paid or payable by the Company in respect of the securities because of any law, together with interest at a rate the Board may determine from the date of payment to the date of repayment, and may deduct or set off against any dividend, bonus or other money payable any money paid or payable by the Company together with interest; (iv) may recover as a debt due from the holder or the holder's personal representative or any person who becomes registered as the holder of the securities on the distribution of the deceased holder's estate, any money paid by the Company because of any law which exceeds any dividend, bonus or other money then due or payable by the Company to the holder together with interest at a rate the Board may determine from the date of payment to the date of repayment; and (v) may, if any money is paid or payable by the Company under any law, refuse to register a transfer of any securities by the holder or the holder's personal representative until the money and interest is set off or deducted or, where the money and interest exceeds the amount of any dividend, bonus or other money then due or payable by the Company to the holder or the holder's personal representative, until the excess is paid to the Company. Nothing in this Rule prejudices or affects any right or remedy which any law confers on the Company and any right or remedy enforceable by the Company, whether against the holder or the holder's personal representative. ljhp P0110103481v1 60-4955093 Page8

Constitution Transfer and transmission of securities 24. Instrument of transfer required I Allens Arthur Robinson_1 _ No transfer of any securities may be registered unless a proper instrument of transfer, in writing in the usual or common form or in any form the Board may prescribe or in a particular case accept, signed by both the transferee and transferor and duly stamped (if necessary) is delivered to the Company (but the Board may dispense with the execution of the instrument by the transferee if the Board thinks fit). 25. Board may refuse to register The Board in its discretion may refuse to register any transfer of shares and may decline to give its reasons and grounds for doing so. 26. When transfer effective The transferor is deemed to remain the holder of the securities transferred until the name of the transferee is entered in the Register. 27. Closing Register The Register may be closed at any time the Board thinks fit. 28. Instrument of transfer and certificate (if any) (a) Every transfer must be left for registration at the Office or any other place the Board determines. Unless the Board otherwise determines either generally or in a particular case, the transfer is to be accompanied by the certificate for the securities to be transferred. In addition, the transfer is to be accompanied by any other evidence which the Board may require to prove the title of the transferor, the transferor's right to transfer the securities, due execution of the transfer or due compliance with the provisions of any law relating to stamp duty. (b) Subject to Rule 28(a), on each application to register the transfer of any securities or to register any person as the holder in respect of any securities transmitted to that person by operation of law or otherwise, the certificate (if any) specifying the securities in respect of which registration is required must be delivered to the company for cancellation and on registration the certificate is taken to have been cancelled. (c) Each transfer which is registered may be retained by the Company for any period determined by the Board after which the Company may destroy it. ljhp P0110103481v1 60-4955093 Page9

Constitution 29. Transmission on death I Allens Arthur Robinson-,- The personal representative of a deceased shareholder (who is not one of several joint holders) is the only person recognised by the Company as having any title to securities registered in the name of the deceased shareholder. Subject to compliance by the transferee with this Constitution, the Board may register any transfer signed by a shareholder prior to the shareholder's death despite the Company having notice of the shareholder's death. 30. Transmission by operation of law A person (a transmittee) who establishes to the satisfaction of the Board that the right to any securities has devolved on the transmittee by will or by operation of law may be registered as a holder in respect of the securities or may (subject to the provisions in this Constitution relating to transfers) transfer the securities. The Board has the same right to refuse to register the transmittee as would apply under Rule 25 if the transmittee was the transferee named in a transfer presented for registration. Alteration of capital 31. Power to alter share capital The Company in general meeting may reduce or alter its share capital in any manner provided by the Corporations Act. The Board may do anything which is required to give effect to any resolution authorising reduction or alteration of the share capital of the Company and, without limitation, may make provision for the issue of fractional certificates or sale of fractions of shares and distribution of net proceeds as it thinks fit. General Meetings 32. General meetings A Director may convene a general meeting of the Company whenever the Director thinks fit. 33. Notice of general meeting A notice of a general meeting must specify the place and time of the meeting, the general nature of the business to be transacted at the meeting and any other matters required by the Corporations Act. The non-receipt of a notice of any general meeting by, or the accidental omission to give notice to, any person entitled to notice does not invalidate any resolution passed at that meeting. ljhp P0110103481v1 60-4955093 Page 10

Constitution I Allens Arthur Robinson_!'_ 34. Quorum Two shareholders present constitute a quorum for a meeting unless there is only one shareholder in which case their membership constitutes a quorum for a meeting. No business may be transacted at any meeting, except the election of a Chairman and the adjournment of the meeting, unless a quorum is present at the commencement of the meeting. 35. Adjournment in absence of quorum If there is not a quorum at a general meeting within 30 minutes after the time specified in the notice of meeting, the meeting is dissolved, unless the Board adjourns the meeting to a date time and place determined by it. If no quorum is present at any adjourned meeting within 30 minutes after the time for the meeting, the meeting is dissolved. 36. Chairman (a) If the Board has elected a Chairman of the Board that person is entitled to chair every general meeting. (b) If at any general meeting the Chairman of the Board: (i) is not present at the specified time for holding the meeting; or (ii) is present but is unwilling to act as chairman of the meeting, the Deputy Chairman of the Board is entitled to chair the meeting. (c) If at any general meeting: (i) there is no Chairman of the Board or Deputy Chairman of the Board; (ii) the Chairman of the Board and Deputy Chairman of the Board are not present at the specified time for holding the meeting; or (iii) the Chairman of the Board and the Deputy Chairman of the Board are present but each is unwilling to chair the meeting, the Directors present may choose another Director to chair the meeting and if no Director is present or if each of the Directors present is unwilling to chair the meeting, a shareholder chosen by the shareholders present may chair the meeting. 37. General conduct of meeting (a) The general conduct of each general meeting of the Company and the procedures to be adopted at the meeting are as determined at, during or prior to the meeting by the Chairman. (b) At any time the Chairman considers it necessary or desirable for the proper and orderly conduct of the meeting, the Chairman may demand the cessation of debate or discussion on any business, question, motion or resolution being considered by ljhp P0110103481v1 60-4955093 Page 11

Constitution I Allens Arthur Robinson-,- the meeting and require the business, question, motion or resolution to be put to a vote of the shareholders present. (c) The Chairman may require the adoption of any procedures which are in the Chairman's opinion necessary or desirable for the proper and orderly casting or recording of votes at any general meeting of the Company, whether on a show of hands or on a poll. (d) Any determination by the Chairman in relation to matters of procedure or any other matter arising directly or indirectly from the business is fixed. Any challenge to a right to vote (whether on a show of hands or on a poll) may only be made at the meeting and may be determined by the Chairman whose decision is final. 38. Adjournment During the course of the meeting the Chairman may adjourn the meeting or any business, motion, question or resolution being considered or remaining to be considered by the meeting or any debate or discussion either to a later time at the same meeting or to an adjourned meeting. If the Chairman exercises a right of adjournment of a meeting under this Rule, the Chairman has the sole discretion to decide whether to seek the approval of the shareholders present to the adjournment and, unless the Chairman exercises that discretion, no vote may be taken by the shareholders present in respect of the adjournment. No business may be transacted at any adjourned meeting other than the business left unfinished at the meeting from which the adjournment took place. 39. Voting on show of hands Each question submitted to a general meeting is to be decided by a show of hands of the shareholders present and entitled to vote, unless a poll is demanded. In the case of an equality of votes, the Chairman has, both on a show of hands and at a poll, a casting vote in addition to the vote or votes to which the Chairman may be entitled as a shareholder or as a proxy, attorney or duly appointed representative of a shareholder. Unless a poll is demanded, a declaration by the Chairman that a resolution has been passed or lost is conclusive. 40. When a poll may be demanded A poll may be demanded by a shareholder in accordance with the Corporations Act (and not otherwise) or by the Chairman. No poll may be demanded on the election of a chairman of a meeting or, unless the Chairman otherwise determines, the adjournment of the meeting. The demand for a poll may be withdrawn. ljhp P0110103481v1 60-4955093 Page 12

Constitution I Allens Arthur Robinson_1 _ 41. Taking a poll (a) If a poll is demanded as provided in Rule 40, it is to be taken in the manner and at the time and place as the Chairman directs, and the result of the poll is the meeting's resolution of the motion on which the poll was demanded. (b) A demand for a poll does not prevent the continuance of a meeting for the transaction of any business other than the question on which a poll has been demanded. A poll demanded on any question of adjournment is to be taken at the meeting and without adjournment. 42. Special meetings All the provisions of this Constitution as to general meetings apply to any special meeting of any class of shareholders which may be held under the operation of this Constitution or the Corporations Act. Votes of shareholders 43. Voting rights Subject to restrictions on voting affecting any class of shares and subject to Rules S(f) and 46: (a) on a show of hands: (i) subject to paragraphs (ii) and (iii), each shareholder present has one vote; (ii) where a shareholder has appointed more than one person as representative, proxy or attorney for the shareholder, none of the representatives, proxies or attorneys is entitled to vote; (iii) where a person is entitled to vote because of paragraph (i) in more than one capacity, that person is entitled only to one vote; and (b) on a poll, each shareholder present: (i) has one vote for each fully paid share held; and (ii) for each other share held, has a vote in respect of the share which carries the same proportionate value as the proportion of the amount paid up or agreed to be considered as paid up on the total issue price of that share at the time the poll is taken bears to the total issue price of the share. 44. Voting rights of personal representatives, etc Where a person satisfies the Board at least 48 hours (or a lesser period as the Board may determine and stipulate in the notice of meeting) before the holding of a general meeting (unless the person has previously satisfied the Board as to the person's right to vote) that the person is a personal representative as referred to in Rule 29 or a transmittee as referred to in Rule 30, the person may vote at the general meeting in the same manner as ljhp P0110103481v1 60-4955093 Page 13

_ I_ Constitution Allens Arthur Robinson 1 if the person were the registered holder of the securities referred to in Rule 29 or 30, as the case requires. 45. Proxies (a) A shareholder who is entitled to attend and cast a vote at a meeting of the Company may appoint a person as a proxy to attend and vote for the member in accordance with the Corporations Act but not otherwise. A proxy appointed to attend and vote in accordance with the Corporations Act may exercise the rights of the shareholder on the basis and subject to the restrictions provided in the Corporations Act but not otherwise.

Constitution Managing Director 59. Appointment of a Managing Director I Allens Arthur Robinson_1 _ The Board may appoint one or more of its members to be Managing Director (who may bear that title or any other title determined by the Board) for a period ending on the happening of events (if any) stipulated by the Board (and, in any event, upon the Managing Director ceasing to hold office as a Director), and at a remuneration which may be by way of salary or commission on or participation in profits or by any or all of these methods and otherwise on terms determined by the Board. The Board may confer on and withdraw from a Managing Director any of the powers exercisable under this Constitution by the Board as it thinks fit and on any conditions it thinks expedient but the conferring of powers by the Board on a Managing Director does not exclude the exercise of those powers by the Board. A Managing Director's appointment automatically terminates if the Managing Director ceases to be a Director for any reason. Proceedings of Directors 60. Procedures relating to Board meetings The Board may meet together, adjourn and otherwise regulate its meetings as it thinks fit. Until otherwise determined by the Board, two Directors form a quorum. The Board may at any time, and the Secretary, on the request of any two Directors, must, convene a meeting of the Board.

Meetings by telephone or other means of communication The Board may meet either in person or by telephone or by using any other technology consented to by all the Directors. A consent may be a standing one. A Director may only withdraw consent within a reasonable period before the meeting. A meeting conducted by telephone or by other means of communication is considered to be held at the place agreed on by the Directors attending the meeting if at least one of the Directors present at the meeting was at that place for the duration of the meeting. 62. Votes at meetings Questions arising at any meeting of the Board are decided (where there is more than one Director of the Company) by a majority of votes. In the case of an equality of votes, the chairman of the meeting appointed under Rule 63 has (except when only two Directors are present or except when only two Directors are competent to vote on the question then at issue) a second or casting vote. ljhp P0110103481v1 60-4955093 Page 19

Constitution 63. Chairman and Deputy Chairman I Allens Arthur Robinson_1 _ The Board may elect a chairman and a deputy chairman of its meetings and determine the period for which each is to hold office.

Committees (a) The Board may delegate any of its powers to Committees consisting of any one or more Directors or any other person or persons as the Board thinks fit. In the exercise of delegated powers, any Committee formed or person or persons appointed to the Committee must conform to any regulations that may be imposed by the Board. A delegate of the Board may be authorised to sub-delegate any of the powers for the time being vested in the delegate. (b) The meetings and proceedings of any Committee are to be governed by the provisions of this Constitution for regulating the meetings and proceedings of the Board so far as they are applicable and are not superseded by any regulations made by the Board under Rule 65{a). 66. Validity of acts (a) All actions at any meeting of the Board or by a Committee or by any person acting as a Director are, despite the fact that it is afterwards discovered that there was some defect in the appointment of any of the Directors or the Committee or the person acting as a Director or that any of them were disqualified, as valid as if every person had been duly appointed and was qualified and continued to be a Director or a member of the Committee. {b) If the number of Directors is reduced below the minimum number fixed under this Constitution, the continuing Directors may act for the purpose of increasing the number of Directors to that number or of calling a general meeting of the Company but for no other purpose. 67. Resolution in writing (a) Subject to Rule 67{b), a resolution in writing signed by all Directors or a resolution in writing of which notice has been given to all Directors and which is signed by a majority of the Directors entitled to vote on the resolution (not being less than the ljhp P0110103481v1 60-4955093 Page 20

Constitution I Allens Arthur Robinson_1 _ number required for a quorum at a meeting of the Board) is a valid resolution of the Board and is effective when signed by the last of all the Directors or the last of the Directors constituting the majority, as required. The resolution may consist of several documents in the same form, each signed by one or more of the Directors. For the purposes of this Rule the references to Directors include any alternate Director for the time being present in Australia who is appointed by a Director not for the time being present in Australia but do not include any other alternate Director. A facsimile transmission or other document produced by mechanical or electronic means under the name of a Director with the Director's authority is considered to be a document in writing signed by the Director. {b) Where there is only one Director of the Company, nothing in this Constitution limits the powers of that Director under the Corporations Act to: (i) pass a resolution; or (ii) make a declaration, by recording it and signing the record. Powers of the Board 68.

Power to borrow and guarantee Without limiting the generality of Rule 68, the Board may exercise all the powers of the Company to raise or borrow money, may guarantee the debts or obligations of any person and may enter into any other financing arrangement, in each case in the manner and on the terms it thinks fit. 70. Power to give security Without limiting the generality of Rule 68, the Board may charge any property or business of the Company or any of its uncalled capital and may issue debentures or give any other security for a debt, liability or obligation of the Company or of any other person, in each case in the manner and on the terms it thinks fit. 71. Power to authorise debenture holders, etc to make calls Without limiting the generality of Rule 68, if any uncalled capital of the Company is included in or charged by any debenture, mortgage or other security, the Board, may authorise the ljhp P0110103481 v1 60-4955093 Page 21

Constitution I Allens Arthur Robinson_1 _ person in whose favour the debenture, mortgage or other security is executed or any other person in trust for the person to make calls on the shareholders in respect of that uncalled capital and to sue in the name of the Company or otherwise for the recovery of money becoming due in respect of calls made and to give valid receipts for that money, and the authority continues for the duration of the debenture, mortgage or other security, despite any change in the Directors, and is assignable if expressed to be. 72. Po~er to issue bond, debenture or other security Any bond, debenture or other security may be issued with or without the right of or obligation on the holder to exchange the bond, debenture or security in whole or in part for shares in the Company at any time and with any special privileges as to redemption, surrender, drawings, allotment of shares, attending and voting at general meetings of the Company, appointment of Directors and with the general rights and on the conditions as the Board thinks fit. 73.

Constitution Dividends 75. Declaration of dividend I Allens Arthur Robinson_1 _ The Board may declare a dividend to be paid to the shareholders entitled. The dividend is (subject to the rights of, or any restrictions on, the holders of shares created or raised under any special arrangement as to dividend) payable on each share on the basis of the proportion which the amount paid is of the total amounts paid, agreed to be considered to be paid or payable on the share. The dividend may be declared at a rate per annum in respect of a specified period but no amount paid on a share in advance of calls is to be treated as paid on that share. 76. Interim Dividends The Board may pay to the shareholders on account of any dividend any interim dividend it thinks fit. 77. Distribution otherwise than in cash When declaring a dividend, the Board may determine that: (a) payment of the dividend be effected wholly or in part by the distribution of specific assets or documents of title and in particular by the issue or transfer of paid-up shares, debentures, debenture stock or grant of options of the Company or any other corporation. Where any difficulty arises in regard to the distribution, the Board may settle the difficulty as it thinks fit and in particular may issue fractional certificates, may fix the value for distribution of the specific assets, may determine that cash payments are to be made to any shareholders on the basis of the value fixed in order to adjust the rights of all parties and may vest the specific assets in trustees on trusts for the persons entitled to the dividend as the Board thinks fit; and (b) the dividend be payable to particular shareholders wholly or partly out of any particular fund or reserve or out of profits derived from any particular source and to the remaining shareholders wholly or partly out of any other particular fund or reserve or out of profits derived from any other particular source. The Board may determine this despite the fact that the dividend may form part of the assessable income for taxation purposes of some shareholders, and may not form part of the assessable income of others. 78. Capitalisation of profits (a) The Board may resolve that the whole or any portion of any sum forming part of the undivided profits of the Company or standing to the credit of any reserve or other account, and which is available for distribution, be capitalised and distributed to shareholders in the same proportions in which the shareholders would be entitled ljhp P0110103481v1 60-4955093 Page 23

Constitution I Allens Arthur Robinson-c to receive it if distributed by way of dividend or in accordance with either the terms of issue of any shares or the terms of any plan for the issue of securities for the benefit of officers or employees and that all or any part of the sum be applied on their behalf either in paying up the amounts for the time being unpaid on any issued shares held by them, or in paying up in full unissued shares or other securities of the Company to be issued to them accordingly, or partly in one way and partly in the other. (b) The Board may specify the manner in which any fractional entitlements and any difficulties relating to distribution are to be dealt with, including specifying that fractions are to be disregarded or that any fractional entitlements are to be increased to the next whole number or that payments in cash in lieu of fractional entitlements be made. (c) The Board may make all necessary appropriations and applications of the amount to be capitalised under Rule 78(a) and all necessary allotments and issues of fully paid shares or debentures. (d) Where required, the Board may appoint a person to sign a contract on behalf of the shareholders entitled on a capitalisation to any shares or other securities, which provides for the issue to them, credited as fully paid, of any further shares or other securities or for the payment by the Company on their behalf of the amounts or any part of the amounts remaining unpaid on their existing shares or other securities by the application of their respective proportions of the sum resolved to be capitalised. 79. Transfer of shares A transfer of shares registered after the transfer books close for dividend purposes, but before a dividend is payable, does not pass the right to any dividend declared before the books are closed. 80. Retention of dividends The Board may retain the dividends payable on securities referred to in Rules 29 and 30 until the personal representative or the transmittee (as the case requires) becomes registered as the holder of the securities or duly transfers them. The Board may retain any dividends in respect of which (or in respect of the shares on which the dividend is payable) the Company has a lien or charge under Rule 20 and may apply any retained dividends towards satisfaction of the calls, instalments or sums owing in respect of which the lien or charge exists. 81. How dividends are payable; currency of payments (a) Payment of any dividend may be made in any manner and by any means as determined by the Board. Without affecting any other method of payment which the Board may adopt, in each case at the risk of the shareholder, payment may be made to the shareholder entitled to the dividend or, in the case of joint holders, to ljhp P0110103481v1 60-4955093 Page 24

-'- Constitution Allens Arthur Robinson 1 the shareholder whose name stands first in the Register in respect of the joint holding. (b) Payments of dividends and other distributions by the Company may be made in Australian dollars or any other currency determined by the Board in its discretion. Payments in different currencies may be made to different shareholders as determined by the Board in its discretion. If a payment is made in a currency other than Australian dollars the Board may determine in its discretion the appropriate exchange rate and the time of calculation to calculate the amount payable in the relevant currency. The determinations of the Board are, in the absence of manifest error, final. 82. Unclaimed dividends All unclaimed dividends may be invested or otherwise made use of by the Board for the benefit of the Company until claimed or otherwise disposed of according to law. Notices 83. Service of notices A notice may be given by the Company to any shareholder, or in the case of joint holders to the shareholder whose name stands first in the Register, personally, by leaving it at the shareholder's registered address or by sending it by prepaid post or facsimile transmission addressed to the shareholder's registered address or, in any other case, by other electronic means determined by the Board. If the notice is signed, the signature may be original or printed. 84. When notice taken to be served Any notice sent by post is taken to have been served at the expiration of 24 hours after the envelope containing the notice is posted and, in proving service, it is sufficient to prove that the envelope containing the notice was properly addressed and posted. Any notice served on a shareholder personally or left at the shareholder's registered address is taken to have been served when delivered. Any notice served on a shareholder by facsimile transmission is taken to have been served when the transmission is sent. 85. Shareholder not known at registered address Where a shareholder does not have a registered address or where the Company has a reason in good faith to believe that a shareholder is not known at the shareholder's registered address, a notice is taken to be given to the shareholder if the notice is exhibited in the Office for a period of 48 hours (and is taken to be duly served at the commencement of that period) unless and until the shareholder informs the Company of a registered place of address. ljhp P0110103481v1 60-4955093 Page 25

Constitution 86. Calculation of period of notice I Allens Arthur Robinson_1 _ If a given number of days' notice or notice extending over any other period is required to be given the day of service is not to be counted in the number of days or other period. 87. Notice to transferor binds transferee Eve~ person who, by operation of law, transfer or any other means, becomes entitled to be registered as the holder of any shares is bound by every notice which, prior to the person's name and address being entered in the Register in respect of the shares, was duly given to the person from whom the title to the shares is derived. 88. Service on deceased shareholders A notice served in accordance with this Constitution is (despite the fact that the shareholder is then dead and whether or not the Company has notice of the shareholder's death) taken to have been duly served in respect of any registered shares, whether held solely or jointly with other persons by the shareholder, until some other person is registered in the shareholder's place as the holder or joint holder. The service is sufficient service of the notice or document on the shareholder's personal representative and any persons jointly interested with the shareholder in the shares. Winding up 89. Distribution in specie If the Company is wound up, whether voluntarily or otherwise, the liquidator may divide among all or any of the contributories as the liquidator thinks fit in specie or kind any part of the assets of the Company, and may vest any part of the assets of the Company in trustees on any trusts for the benefit of all or any of the contributories as the liquidator thinks fit. 90. Variation of rights of contributories Any division may be otherwise than in accordance with the legal rights of the contributories and, in particular, any class may be given preferential or special rights or may be excluded altogether or in part, but if any division otherwise than in accordance with the legal rights of the contributories is determined, any contributory who would be prejudiced by the division has a right to dissent and ancillary rights as if the determination were a special resolution passed under the Corporations Act relating to the sale or transfer of the Company's assets by a liquidator in a voluntary winding up. 91. Liability to calls If any shares to be divided in accordance with Rule 89 involve a liability to calls or otherwise, any person entitled under the division to any of the shares may, by notice in ljhp P0110103481v1 60-4955093 Page26
