All Warrants issued to the Depository may be in either a certificated or uncertificated form, such uncertificated form being evidenced by a book position on the register of Warrantholders to be maintained by the Warrant Agent in accordance with Section 2.8. For greater certainty, any Registered Warrantholder holding Warrants represented by an Uncertificated Warrant may, at any time prior to the Expiry Time, request that such Warrants be evidenced by a Warrant Certificate.

2.5.2Each Warrantholder, by purchasing Warrants, acknowledges and agrees that the terms and conditions set forth in the form of Warrant Certificate set out in Schedule A hereto shall apply to all Warrants and Warrantholders, regardless of whether such Warrants are issued in certificated or  uncertificated form, or whether such Warrantholders are Registered Warrantholders or owners of Warrants who beneficially hold securities entitlements in respect of the Warrants through a Book-Based Participant.

2.6Beneficial Holders of Warrants

2.6.1The Warrants may be represented in the form of one or more Global Certificate registered in the name of the Depository or its nominee and held by, or on behalf of, the Depository, as Depository of the Global Certificates for the participants of CDS, and any such Global Certificate will bear, or be deemed to bear the legend included on the form of Global Certificate appended as Schedule A hereto.

2.6.2Registration of beneficial interests in and transfers of Warrants held by the Depository shall be made only through the Book-Based System and no Warrant Certificates shall be issued in respect of such Warrants except where physical certificates evidencing ownership in such securities are required or as set out herein or as may be requested by the Depository, as determined by the Corporation, from time to time. Except as provided in this Section 2.6, owners of beneficial interests in any Global Certificates shall not be entitled to have Warrants registered in their names and shall not receive or be entitled to receive Warrants in definitive form or to have their names appear in the register referred to in Section 2.8 herein.

12

2.6.3Notwithstanding any other provision in this Indenture, no Global Certificate may be exchanged in whole or in part for Warrants registered, and no transfer of Global Certificates in whole or in part may be registered, in the name of any person other than the Depository for such Global Certificates or a nominee thereof unless:

(i)the Depository notifies the Corporation that it is unwilling or unable to continue to act as depository in connection with the Book-Based Warrants and the Corporation is unable to locate a qualified successor;

(ii)the Corporation determines that the Depository is no longer willing, able or qualified to discharge properly its responsibilities as holder of the Global Certificates and the Corporation is unable to locate a qualified successor;

(iii)the Depository ceases to be a clearing agency or otherwise ceases to be eligible to be a depository and the Corporation is unable to locate a qualified successor;

(iv)the Corporation determines that the Warrants shall no longer be held as Book-Based Warrants through the Depository;

(v)such right is required by Applicable Legislation, as determined by the Corporation and the Corporation's counsel; or

(vi)such registration is effected in accordance with the Internal Procedures as well as with the internal procedures of the Depository;

following which Warrants for those holders requesting such exchange shall be issued to the beneficial owners of such Warrants or their nominees as directed by the holder. The Corporation shall provide an officer's certificate giving notice to the Warrant Agent of the occurrence of any event outlined in this Section 2.6.3(i)-(v).

2.6.4Subject to the provisions of this Section 2.6, any exchange of Global Certificates for Warrants which are not Global Certificates may be made in whole or in part in accordance with the provisions of Section 2.10, mutatis mutandis. All such Warrants issued in exchange for a Global Certificate or any portion thereof shall be registered in such names as the Depository for such Global Certificates shall direct and shall be entitled to the same benefits and subject to the same terms and conditions (except insofar as they relate specifically to Global Certificates) as the Global Certificates or portion thereof surrendered upon such exchange.

13

2.6.5Every Warrant Authenticated upon registration of transfer of Global Certificates, or in exchange for or in lieu of Global Certificates or any portion thereof, whether pursuant to this Section 2.6, or otherwise, shall be Authenticated in the form of, and shall be, a Global Certificate, unless such Warrant is registered in the name of a person other than the Depository for such Global Certificate or a nominee thereof.

2.6.6Notwithstanding anything to the contrary in this Indenture, subject to Applicable Legislation, any Global Certificate will be issued as an Uncertificated Warrant, unless otherwise requested in writing by the Depository or the Corporation.

2.6.7The rights of beneficial owners of Warrants who hold securities entitlements in respect of the Warrants through the Book-Based System shall be limited to those established by applicable law and agreements between the Depository and the Book-Based Participants and between such Book-Based Participants and the beneficial owners of Warrants who hold securities entitlements in respect of the Warrants through the Book-Based System, and such rights must be exercised through a Book-Based Participant in accordance with the rules and procedures of the Depository.

2.6.8Notwithstanding anything herein to the contrary, neither the Corporation nor the Warrant Agent nor any agent thereof shall have any responsibility or liability for:

(i)any aspects of the records relating to any beneficial ownership interests in the Warrants or the Book-Based System, or payments made by the Depository or its nominee on account of any beneficial ownership interest of any person in any Warrant represented by an electronic position in the Book-Based System;

(ii)maintaining, supervising or reviewing any records of the Depository or its nominee or any Book-Based Participant relating to any such interest; or

(iii)any advice or representation made or given by the Depository or those contained herein that relate to the rules and regulations of the Depository or any action to be taken by the Depository on its own direction or at the direction of any Book-Based Participant.

2.6.9The Corporation may terminate the application of this Section 2.6 in its sole discretion in which case all Warrants shall be evidenced by Warrant Certificates registered in the name of person(s) other than the Depository.

2.7Warrant Certificate

2.7.1For Warrants issued in certificated form, the form of certificate representing Warrants shall be substantially as set out in Schedule A hereto or such other form as is authorized from time to time by the Warrant Agent. Each Warrant Certificate shall be Authenticated manually on behalf of the Warrant Agent. Each Warrant Certificate shall be signed by any duly authorized signatory of the Corporation; whose signature shall appear on the Warrant Certificate and may be printed, lithographed or otherwise mechanically reproduced thereon and, in such event, certificates so signed are as valid and binding upon the Corporation as if it had been signed manually. Any Warrant Certificate shall be valid notwithstanding that any person whose signature is printed, lithographed or mechanically reproduced no longer holds office at the date of issuance of such certificate. The Warrant Certificates may be engraved, printed or lithographed, or partly in one form and partly in another, as the Warrant Agent may determine.

14

2.7.2Any Warrant Certificate validly issued in accordance with the terms of this Indenture in effect at the time of issue of such Warrant Certificate shall, subject to the terms of this Indenture and applicable law, validly entitle the holder to acquire Shares, notwithstanding that the form of such Warrant Certificate may not be in the form currently required by this Indenture.

2.7.3The Warrant Agent shall Authenticate Uncertificated Warrants (whether upon original issuance, exchange, partial exercise, registration of transfer, or otherwise) by completing its Internal Procedures and the Corporation shall, and hereby acknowledges that it shall, thereupon be deemed to have duly and validly issued such Uncertificated Warrants under this Indenture. Such Authentication shall be conclusive evidence that such Uncertificated Warrants have been duly issued hereunder and that the holder or holders are entitled to the benefits of this Indenture. The register shall be final and conclusive evidence as to all matters relating to Uncertificated Warrants with respect to which this Indenture requires the Warrant Agent to maintain records or accounts. In case of differences between the register at any time and any other time the register at the later time shall be controlling, absent manifest error.

2.7.4No Certificated Warrant shall be considered issued and Authenticated or, if Authenticated, shall be obligatory or shall entitle the holder thereof to the benefits of this Indenture, until it has been Authenticated by manual signature by or on behalf of the Warrant Agent substantially as contemplated in the form of the Warrant set out in Schedule A hereto. Such Authentication on any such Certificated Warrant shall be conclusive evidence that such Certificated Warrant is duly Authenticated and is valid and a binding obligation of the Corporation and that the holder is entitled to the benefits of this Indenture. The Authentication by the Warrant Agent on any such Certificated Warrant hereunder shall not be construed as a representation or warranty by the Warrant Agent as to the validity of this Indenture or of such Warrant or its issuance (except the due Authentication thereof) or as to the performance by the Corporation of its obligations under this Indenture and the Warrant Agent shall in no respect be liable or answerable for the use made of the Warrants or any of them or the proceeds thereof.

15

2.7.5No Uncertificated Warrant shall be considered issued and shall be obligatory or shall entitle the holder thereof to the benefits of this Indenture, until it has been Authenticated by entry on the register of the particulars of the Uncertificated Warrant. Such entry on the register of the particulars of an Uncertificated Warrant shall be conclusive evidence that such Uncertificated Warrant is a valid and binding obligation of the Corporation and that the holder is entitled to the benefits of this Indenture. Authenticating by way of entry on the register shall not be construed as a representation or warranty by the Warrant Agent as to the validity of this Indenture or of such Warrants (except the due Authentication thereof) or as to the performance by the Corporation of its obligations under this Indenture and the Warrant Agent shall in no respect be liable or answerable for the use made of the Uncertificated Warrants or any of them or the proceeds thereof.

2.8Register of Warrants

2.8.1The Warrant Agent shall maintain records and accounts concerning the Warrants, whether certificated or uncertificated, which shall contain the information called for below with respect to each Warrant, together with such other information as may be required by Applicable Legislation or as the Warrant Agent may elect to record. All such information shall be kept in one set of accounts and records which the Warrant Agent shall designate (in such manner as shall permit it to be so identified as such by an unaffiliated party) as the register of the holders of Warrants. The information to be entered for each account in the register of Warrants at any time shall include (without limitation):

(i)the name and address of the holder of the Warrants, the date of Authentication thereof and the number of Warrants;

(ii)whether such Warrant is a Certificated Warrant or an Uncertificated Warrant and, if a Warrant Certificate, the unique number or code assigned to and imprinted thereupon and, if an Uncertificated Warrant, the unique number or code assigned thereto if any;

(iii)whether such Warrant has been cancelled; and

(iv)a register of transfers in which all transfers of Warrants and the date and other particulars of each transfer shall be entered.

2.8.2The register shall be available for inspection by the Corporation or any Warrantholder during the Warrant Agent's regular business hours on a Business Day. Any Warrantholder exercising such right of inspection shall first provide an affidavit in form satisfactory to the Corporation and the Warrant Agent, each acting reasonably, stating the name and address of the Warrantholder and agreeing not to use the information therein except in connection with an effort to call a meeting of Warrantholders or to influence the voting of Warrantholders at any meeting of Warrantholders.

16

2.8.3Once an Uncertificated Warrant has been Authenticated, the information set forth in the register with respect thereto at the time of Authentication may be altered, modified, amended, supplemented or otherwise changed only to reflect exercise or proper instructions to the Warrant Agent from the Registered Warrantholder as provided herein, except that the Warrant Agent may act unilaterally to make purely administrative changes internal to the Warrant Agent and changes to correct errors. Each person who becomes a holder of an Uncertificated Warrant, by his, her or its acquisition thereof shall be deemed to have irrevocably (i) consented to the foregoing authority of the Warrant Agent to make such error corrections and (ii) agreed to pay to the Warrant Agent, promptly upon written demand, the full amount of all loss and expense (including without limitation reasonable legal fees of the Warrant Agent) plus interest, at an appropriate then prevailing rate of interest, sustained by the Warrant Agent as a proximate result of such error if but only if and only to the extent that such present or former holder realized any benefit as a result of such error and could reasonably have prevented, forestalled or minimized such loss and expense by prompt reporting of the error or avoidance of accepting benefits thereof whether or not such error is or should have been timely detected and corrected by the Warrant Agent; provided, that no person who is a bona fide purchaser shall have any such obligation to the Warrant Agent.

2.9Issue in Substitution for Warrant Certificates Lost, etc.

2.9.1If any Warrant Certificate becomes mutilated or is lost, destroyed or stolen, the Corporation, subject to applicable law, shall issue and thereupon the Warrant Agent shall certify and deliver, a new Warrant Certificate of like tenor and bearing the same legend, as applicable, as the one mutilated, lost, destroyed or stolen in exchange for and in place of and upon cancellation of such mutilated Warrant Certificate, or in lieu of and in substitution for such lost, destroyed or stolen Warrant Certificate, and the substituted Warrant Certificate shall be in a form approved by the Warrant Agent and the Warrants evidenced thereby shall be entitled to the benefits hereof and shall rank equally in accordance with its terms with all other Warrants issued or to be issued hereunder.

2.9.2The applicant for the issue of a new Warrant Certificate pursuant to this Section 2.9 shall bear the cost of the issue thereof and in case of loss, destruction or theft shall, as a condition precedent to the issuance thereof, furnish to the Corporation and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft of the Warrant Certificate so lost, destroyed or stolen as shall be satisfactory to the Corporation and to the Warrant Agent, in their sole discretion, and such applicant may also be required to furnish an indemnity, surety bond or security in amount and form satisfactory to the Corporation and the Warrant Agent, in their sole discretion, and shall pay the reasonable charges of the Corporation and the Warrant Agent in connection therewith.

2.9.3Warrant Certificates may be replaced only at the Warrant Agency or at any other place that is designated by the Corporation with the approval of the Warrant Agent.

17

2.10Exchange of Warrant Certificates

2.10.1Any one or more Warrant Certificates representing any number of Warrants may, upon compliance with the reasonable requirements of the Warrant Agent (including compliance with applicable securities legislation), be exchanged for one or more other Warrant Certificates representing the same aggregate number of Warrants as represented by the Warrant Certificate or Warrant Certificates so exchanged. Warrant Certificates exchanged for Warrant Certificates that bear the legend set forth in Section 2.14 shall bear the same legend.

2.10.2Warrant Certificates may be exchanged only at the Warrant Agency or at any other place that is designated by the Corporation with the approval of the Warrant Agent. Any Warrant Certificate tendered for exchange shall be cancelled and surrendered by the Warrant Agency to the Warrant Agent.

2.11Transfer and Ownership of Warrants

2.11.1The Warrants may only be transferred on the register kept by the Warrant Agent at the Warrant Agency by the Registered Warrantholder or its legal representatives or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent only upon (a) in the case of a Warrant Certificate, surrendering to the Warrant Agent at the Warrant Agency the Warrant Certificates representing the Warrants to be transferred together with a duly executed transfer form as set forth in Schedule A, (b) in the case of Book-Based Warrants, in accordance with procedures prescribed by the Depository under the Book-Based System, (c) in the case of Uncertificated Warrants, surrendering to the Warrant Agent at the Warrant Agency, a duly executed Transaction Instruction from the Registered Warrantholder (or such other instructions, in form satisfactory to the Warrant Agent), and (d) upon compliance with:

(i)the conditions herein;

(ii)such reasonable requirements as the Warrant Agent may prescribe; and

(iii)all applicable securities legislation and requirements of regulatory authorities;

and such transfer shall be duly noted in such register by the Warrant Agent. Upon compliance with such requirements, the Warrant Agent shall issue to the transferee of a Certificated Warrant, a Warrant Certificate, and to the transferee of an Uncertificated Warrant, an Uncertificated Warrant (or it shall Authenticate and deliver a Certificated Warrant instead, upon request), representing the Warrants transferred and the transferee of a Book-Based Warrant shall be recorded through the relevant Book-Based Participant in accordance with the Book-Based System as the entitlement holder in respect of such Warrants. Transfers within the Book-Based System are not the responsibility of the Warrant Agent and will not be noted on the register maintained by the Warrant Agent.

18

2.11.2Subject to the provisions of this Indenture and applicable law, the Warrantholder shall be entitled to the rights and privileges attaching to the Warrants, and the issue of Shares by the Corporation upon the exercise of Warrants in accordance with the terms and conditions herein contained shall discharge all responsibilities of the Corporation and the Warrant Agent with respect to such Warrants and neither the Corporation nor the Warrant Agent shall be bound to inquire into the title of any such holder.

2.12Charges for Exchange or Transfer

The transfer or the exchange of any Warrant Certificate or the issue of a new Warrant Certificate pursuant hereto shall be subject to the payment of a reasonable fee levied by the Warrant Agent in addition to the reimbursement of the Warrant Agent or the Corporation for any and all transfer, stamp or similar taxes or other governmental charges required to be paid, and such payment shall be made by the holder requesting a transfer or exchange as a condition precedent to such transfer or exchange.

2.13Cancellation of Surrendered Warrants

2.13.1All Warrants surrendered pursuant to Article 3 shall be cancelled by the Warrant Agent and all such Warrants shall be deemed cancelled and so noted on the register by the Warrant Agent.

2.13.2Upon written request by the Corporation, the Warrant Agent shall furnish to the Corporation a cancellation certificate identifying the number of Warrants so cancelled, identifying the Warrant Certificates, if any, evidencing such Warrants, the number of Shares, if any, issued pursuant to such Warrants and the details of any Warrant Certificates issued in substitution or exchange for any such Warrant Certificates cancelled.

2.14Legended Warrant Certificates

2.14.1Any Global Certificate shall bear a legend in substantially the following form, subject to modification as required by the Depository:

"UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. ("CDS") TO INTELGENX TECHNOLOGIES CORP. (THE "ISSUER") OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO., OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL WITH THIS CERTIFICATE."

2.14.2If the Shares issuable upon the exercise of the Warrants are not registered under the U.S. Securities Act and the securities laws of all applicable states of the United States, the certificate representing the Shares issued upon the exercise of the Warrants shall bear the following restrictive legend:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”). THESE SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) IF THE SECURITIES HAVE BEEN REGISTERED IN COMPLIANCE WITH THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS (C) IN COMPLIANCE WITH THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT IN ACCORDANCE WITH RULE 144 THEREUNDER, IF APPLICABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE LAWS AND REGULATIONS GOVERNING THE OFFER AND SALE OF SECURITIES, AND THE HOLDER HAS, PRIOR TO SUCH SALE, FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING, OR OTHER EVIDENCE OF EXEMPTION, REASONABLY SATISFACTORY TO THE CORPORATION. HEDGING TRANSACTIONS INVOLVING THE SECURITIES REPRESENTED HEREBY MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH U.S. SECURITIES LAWS”.

19

3.EXERCISE OF WARRANTS

3.1Limitation on and Method of Exercise of Warrants

3.1.1The holder of any Warrant may exercise the right conferred on such holder to acquire Shares by surrendering, after the Issue Date and prior to the Expiry Time, to the Warrant Agency, (i) the Warrant Certificate representing such Warrant, with a duly completed and executed Warrant Exercise Form, (ii) together with a certified cheque, money order or bank draft, in lawful money of Canada payable to or to the order of the Corporation at par in the city where the Warrant Agency is located in an amount equal to the Exercise Price multiplied by the number of Shares subscribed for. In accordance with subsection 2.6, if Warrants are exercised through the Depository, the payment of such exercise will be done electronically by the Depository to the Warrant Agent. The Warrant Agent will, within three (3) days, send such payment to the Corporation.

3.1.2A Warrant Certificate with the duly completed and executed Warrant Exercise Form referred to in this Section 3.1 shall be deemed to be surrendered only upon personal delivery thereof or, if sent by mail or other means of transmission, upon actual receipt thereof at, in each case, the Warrant Agency, provided that such Warrant Certificate is accompanied by the requisite certified cheque, bank draft or money order in the amount of the aggregate Exercise Price for the Warrants represented thereby that are being exercised.

3.1.3Any Warrant Exercise Form referred to in Section 3.1 shall be signed by the Warrantholder and shall specify:

(i)the number of Shares which the holder wishes to acquire (being not more than those which the holder is entitled to acquire pursuant to the Warrant Certificate(s) surrendered);

(ii)the person or persons in whose name or names such Shares are to be issued;

(iii)the address or addresses of such person or persons;

(iv)if an individual, the social insurance number of such person or persons; and

(v)the number of Shares to be issued to each such person if more than one is so specified.

If any of the Shares subscribed for are to be issued and registered in the name or names of a person or persons other than the Warrantholder, the Warrantholder shall pay to the Corporation or the Warrant Agency on behalf of the Corporation, all applicable transfer or similar taxes and the Corporation shall not be required to issue or deliver certificates evidencing Shares unless or until such Warrantholder shall have paid to the Corporation, or the Warrant Agency on behalf of the Corporation, the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid or that no tax is due.

20

3.1.4In connection with the exchange of Warrant Certificates and exercise of Warrants and compliance with such other terms and conditions hereof as may be required, the Corporation has appointed the principal offices of the Warrant Agent in Toronto, Ontario as the Warrant Agencies at which Warrant Certificates may be surrendered for exchange, transfer or repurchase or at which Warrants may be exercised and the Warrant Agent has accepted such appointment. The Corporation may from time to time designate alternate or additional places as a Warrant Agency upon notice to and consent of the Warrant Agent of any change of any Warrant Agency. The Corporation shall give notice to Warrantholders of any change of a Warrant Agency.

3.1.5Subject to and upon compliance with the terms of this Section 3, a beneficial holder of Uncertificated Warrants evidenced by a security entitlement in respect of Warrants in the Book-Based System may exercise the right of purchase by causing a Book-Based Participant to deliver to the Depository on behalf of the entitlement holder, notice of the owner's intention to exercise the Warrants in a manner acceptable to the Depository. Forthwith upon receipt by the Depository of such notice, as well as payment for the Exercise Price, the Depository shall deliver to the Warrant Agent a Transaction Instruction confirming its intention to exercise Warrants in a manner acceptable to the Warrant Agent, including by electronic means through the Book-Based System.

3.1.6Payment representing the aggregate Exercise Price must be provided to the appropriate office of the Book-Based Participant in a manner acceptable to it. A notice in form acceptable to the Book-Based Participant and payment from such beneficial holder should be provided to the Book-Based Participant sufficiently in advance so as to permit the Book-Based Participant to deliver notice and payment to the Depository and for the Depository in turn to deliver notice and payment to the Warrant Agent prior to the Expiry Time. The Depository will initiate the exercise by way of the Transaction Instruction and will forward the aggregate Exercise Price electronically to the Warrant Agent and the Warrant Agent will provide delivery instructions to the Corporation following which the Corporation will execute the exercise by facilitating, directly or through its transfer agent, the settlement through the Book-Based System of electronic deposits representing the Shares to which such Warrantholder is entitled pursuant to the exercise. Any expense associated with the exercise process will be for the account of the entitlement holder exercising the Warrants and/or the Book-Based Participant exercising the Warrants on its behalf.

3.1.7By causing a Book-Based Participant to deliver notice to the Depository, a Warrantholder shall be deemed to have irrevocably surrendered his or her Warrants so exercised and appointed such Book-Based Participant to act as his or her exclusive settlement agent with respect to the exercise and the receipt of Shares in connection with the obligations arising from such exercise.

21

3.1.8Any notice which the Depository determines to be incomplete, not in proper form, or not duly-executed shall for all purposes be void and of no effect and the exercise to which it relates shall be considered for all purposes not to have been exercised thereby. A failure by a Book-Based Participant to exercise or to give effect to the settlement thereof in accordance with the Warrantholder's instructions will not give rise to any obligations or liability on the part of the Corporation or Warrant Agent to the Book-Based Participant or the Warrantholder.

3.1.9Any exercise form or other Transaction Instruction referred to in this Section 3 shall be signed by the registered Warrantholder, or its executors or administrators or other legal representatives or an attorney of the registered Warrantholder, duly appointed by an instrument in writing satisfactory to the Warrant Agent but such exercise form need not be executed by the Depository.

3.1.10Any exercise referred to in this Section 3.1 shall require that the entire Exercise Price for Shares subscribed must be paid at the time of subscription and such Exercise Price and original exercise form or other Transaction Instruction executed by the registered Warrantholder or the Depository must be received by the Warrant Agent prior to the Warrant Expiry Time.

3.1.11Notwithstanding any provision to the contrary contained in this Indenture, no Warrantholder may exercise any Warrant at any time when the Registration Statement registering the Shares under the U.S. Securities Act is not effective, unless an exemption from the registration requirements is available and such holder provides evidence of the availability of such exemption satisfactory to the Corporation. The Corporation shall give notice to the Warrant Agent in accordance with Section 5.2.11 if at any time the Registration Statement is not effective.

3.2Effect of Exercise of Warrants

3.2.1Upon the exercise of Warrants pursuant to Section 3.1 and subject to Section 3.3, the Shares to be issued pursuant to the Warrants exercised shall be deemed to have been issued and the person or persons to whom such Shares are to be issued and registered shall be deemed to have become the holder or holders of record of such Shares on the Exercise Date unless the transfer registers of the Corporation shall be closed on such date, in which case the Shares subscribed for shall be deemed to have been issued and such person or persons deemed to have become the holder or holders of record of such Shares, on the date on which such transfer registers are reopened. It is hereby understood that in order for persons to whom Shares are issued to become holders of Shares on record on the Exercise Date, beneficial holders must commence the exercise process sufficiently in advance so that the Warrant Agent is in receipt of all items of exercise at least one Business Day prior to such Exercise Date.

22

3.2.2Within five (5) Business Days after the Exercise Date with respect to a Warrant, the Corporation shall (i) cause to be mailed to the person or persons in whose name or names such Warrant is registered or, (ii) if so specified in writing by the holder, cause to be delivered to such person or persons at the Warrant Agency where the Warrant Certificate was surrendered, a certificate or certificates for the appropriate number of Shares subscribed for or any other appropriate evidence of the issuance of Shares to such person or persons in respect of Shares issued under the Book-Based System.

3.3Partial Exercise of Warrants; Fractions

3.3.1A Warrantholder may exercise his right to acquire a number of Shares less than the aggregate number which the holder is entitled to acquire pursuant to the Warrants he holds. In the event of any exercise of a number of Warrants less than the number which the holder is entitled to exercise, the holder of the Warrants upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new Warrant Certificate(s) bearing the same legend, if applicable, or if he holds Uncertificated Warrants, the Book-Based System will be updated, in respect of the balance of the Warrants which were not then exercised.

3.3.2Notwithstanding anything herein contained including any adjustment provided for in Article 4, neither the Corporation nor the Warrant Agent shall be required, upon the exercise of any Warrants, to issue fractions of Shares or to distribute certificates which evidence fractional Shares. Any fractional entitlements will be rounded down to the nearest whole number.

3.4Expiration of Warrants

Immediately after the Expiry Time, all rights under any Warrant in respect of which the right of acquisition provided for herein shall not have been exercised shall cease and terminate and each Warrant shall be void and of no further force or effect.

3.5Accounting and Recording

3.5.1The Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised and forward to the Corporation (or into an account or accounts of the Corporation with the bank or trust company designated by the Corporation for that purpose), all monies received by the Warrant Agent on the subscription for Shares through the exercise of Warrants. All such monies and any securities or other instruments, from time to time received by the Warrant Agent shall be received in trust for, and shall be segregated and kept apart by the Warrant Agent, the Warrantholders and the Corporation as their interests may appear.

3.5.2The Warrant Agent shall record the particulars of Warrants exercised, which particulars shall include the names and addresses of the persons who become holders of Shares on exercise and the Exercise Date, in respect thereof. The Warrant Agent shall provide such particulars in writing to the Corporation within five (5) Business Days of any request by the Corporation therefor.

23

4.ADJUSTMENT OF NUMBER OF SHARES AND EXERCISE PRICE

4.1Adjustment of Number of Shares and Exercise Price

The acquisition rights as they relate to Shares, in effect at any date attaching to the Warrants, and the Exercise Price in respect thereof, shall be subject to adjustment from time to time as follows:

4.1.1if and whenever at any time during the Adjustment Period, the Corporation shall: (i) subdivide, redivide or change its outstanding Shares into a greater number of shares; (ii) reduce, combine or consolidate its outstanding Shares into a smaller number of shares; or (iii) issue Shares or securities exchangeable for or convertible into Shares to the holders of all or substantially all of the outstanding Shares by way of a stock dividend (other than the issue of Shares to such holders as a dividend paid in the ordinary course), the Exercise Price in effect on the effective date of such subdivision, redivision, change, reduction, combination, consolidation or on the record date of such stock dividend, as the case may be, shall in the case of the events referred to in (i) or (iii) above be decreased in proportion to the number of outstanding Shares resulting from such subdivision, redivision or stock dividend, or shall, in the case of the events referred to in (ii) above, be increased in proportion to the number of outstanding Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this subsection 4.1.1 shall occur. Upon any adjustment of the Exercise Price pursuant to subsection 4.1.1, the number of Shares subject to the right of purchase under each Warrant shall be contemporaneously adjusted by multiplying the number of Shares theretofore obtainable on the exercise thereof by a fraction of which the numerator shall be the respective Exercise Price in effect immediately prior to such adjustment and the denominator shall be the respective Exercise Price resulting from such adjustment;

4.1.2if and whenever at any time during the Adjustment Period, the Corporation shall fix a record date for the issuance of rights, options or warrants to all or substantially all the holders of its outstanding Shares entitling them, for a period expiring not more than forty-five (45) days after such record date, to subscribe for or purchase Shares (or securities convertible or exchangeable into Shares) at a price per share (or having a conversion or exchange price per share) less than ninety-five percent (95%) of the Current Market Price on such record date, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the amount determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Shares outstanding on such record date plus a number of Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by such Current Market Price, and of which the denominator shall be the total number of Shares outstanding on such record date plus the total number of additional Shares offered for subscription or purchase or into which the convertible or exchangeable securities so offered are convertible or exchangeable; any Shares owned by or held for the account of the Corporation or any Subsidiary shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that any such rights or warrants are not exercised prior to the expiration thereof the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based upon the number of Shares (or securities convertible or exchangeable into Shares) actually issued upon the exercise of such rights or warrants, as the case may be. Upon any adjustment of the Exercise Price pursuant to this subsection 4.1.2, the number of Shares subject to the right of purchase under each Warrant shall be contemporaneously adjusted by multiplying the number of Shares theretofore obtainable on the exercise thereof by a fraction of which the numerator shall be the respective Exercise Price in effect immediately prior to such adjustment and the denominator shall be the respective Exercise Price resulting from such adjustment;

24

4.1.3if and whenever at any time during the Adjustment Period the Corporation shall fix a record date for the payment, issue or distribution to all or substantially all the holders of its outstanding Shares of (i) shares of any class, whether of the Corporation or any other corporation (other than Shares and other than shares distributed to holders of Shares pursuant to their exercise of options to receive dividends in the form of such shares in lieu of dividends paid in the ordinary course on the Shares), (ii) rights, options or warrants to subscribe for or purchase Shares (or other securities convertible into or exchangeable for Shares) for a period expiring not more than forty-five (45) days after such record date at a price per share (or having a conversion or exercise price per share) not less than ninety-five percent (95%) of the Current Market Price on such record date), (iii) evidences of its indebtedness or (iv) any property or other assets (excluding dividends paid in the ordinary course) then, in each such case, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Shares outstanding on such record date multiplied by such Current Market Price less the aggregate fair market value (as determined by the directors, acting reasonably, which determination shall be conclusive) of such shares or rights, options or warrants or evidences of indebtedness or assets actually distributed, as the case may be, and of which the denominator shall be the total number of Shares outstanding on such record date multiplied by the Current Market Price on such record date; and Shares owned by or held for the account of the Corporation or any Subsidiary shall be deemed not be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that such distribution is not so made, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based upon such shares or rights, options or warrants or evidences of indebtedness or assets actually distributed, as the case may be. Upon any adjustment of the Exercise Price pursuant to this subsection 4.1.3, the number of Shares subject to the right of purchase under each Warrant shall be contemporaneously adjusted by multiplying the number of Shares theretofore obtainable on the exercise thereof by a fraction of which the numerator shall be the respective Exercise Price in effect immediately prior to such adjustment and the denominator shall be the respective Exercise Price resulting from such adjustment;

25

4.1.4if and whenever at any time during the Adjustment Period, there is a reclassification of the Shares or a capital reorganization of the Corporation other than as described in subsection 4.1.1 or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity in which the holders of Shares are entitled to receive shares, other securities or property, including cash, any Warrantholder who has not exercised its right of acquisition prior to the effective date of such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, upon the exercise of such right thereafter, shall be entitled to receive and shall accept for the same aggregate consideration, in lieu of the number of Shares then sought to be acquired by it, the number of shares or other securities or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such Warrantholder would have been entitled to receive on such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, if, on the record date or the effective date thereof, as the case may be, the Warrantholder had been the registered holder of the number of Shares sought to be acquired by it and to which it was entitled to acquire upon the exercise of the Warrants. If determined appropriate by the Warrant Agent, relying on an opinion of counsel, to give effect to or to evidence the provisions of this subsection 4.1.4, the Corporation, its successor, or such purchasing body corporate, partnership, trust or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, sale or conveyance, enter into an indenture which shall provide, to the extent possible, for the application of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the Warrantholders to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to which a Warrantholder is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Warrant Agent pursuant to the provisions of this subsection 4.1.4 shall be a supplemental indenture entered into pursuant to the provisions of Article 8 hereof. Any indenture entered into between the Corporation; any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Warrant Agent shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 4.1 and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, sales or conveyances;

26

4.1.5in any case in which this Section 4.1 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the holder of any Warrant exercised after such event the additional Shares issuable upon such conversion by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder's right to receive such additional Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Shares declared in favour of holders of record of Shares on and after the relevant date of exercise or such later date as such holder would, but for the provisions of this Section 4.1.5, have become the holder of record of such additional Shares pursuant to Section 4.1.4;

4.1.6in any case in which Sections 4.1.2 or 4.1.3 require that an adjustment be made to the Exercise Price, no such adjustment shall be made if the holders of the outstanding Warrants receive the rights, options or warrants referred to in Section 4.1.2 or the shares, rights, options, warrants, evidences of indebtedness, property or assets referred to in Section 4.1.3, as the case may be, in such kind and number as they would have received if they had been holders of Shares on the applicable record date or effective date, as the case may be, by virtue of their outstanding Warrants having then been exercised into Shares at the Exercise Price in effect on the applicable record date or effective date, as the case may be. Any such issuance of share, rights, options, or warrants will be subject to regulatory approval;

4.1.7the adjustments provided for in this Section 4.1 are cumulative, and shall, in the case of adjustments to the Exercise Price, be computed to the nearest whole cent and shall apply to successive subdivisions, redivisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section 4.1, provided that, notwithstanding any other provision of this Section, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least one (1%) percent in the Exercise Price then in effect; provided, however, that any adjustments which by reason of this subsection 4.1.7 are not required to be made shall be carried forward and taken into account in any subsequent adjustment; and

4.1.8after any adjustment pursuant to this Section 4.1, the term "Shares" where used in this Indenture shall be interpreted to mean securities of any class or classes which, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, the Warrantholder is entitled to receive upon the exercise of his Warrant, and the number of Shares indicated by any exercise made pursuant to a Warrant shall be interpreted to mean the number of Shares or other property or securities a Warrantholder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, upon the full exercise of a Warrant.

27

4.2Entitlement to Shares on Exercise of Warrant

All shares of any class or other securities which a Warrantholder is at the time in question entitled to receive on the exercise of its Warrant, whether or not as a result of adjustments made pursuant to this Article 4, shall, for the purposes of the interpretation of this Indenture, be deemed to be shares which such Warrantholder is entitled to acquire pursuant to such Warrant.

4.3No Adjustment for Certain Transactions

Notwithstanding anything in this Article 4, no adjustment shall be made in the acquisition rights attached to the Warrants if the issue of Shares is being made pursuant to or in connection with:

4.5Proceedings Prior to any Action Requiring Adjustment

As a condition precedent to the taking of any action which would require an adjustment in any of the acquisition rights pursuant to any of the Warrants, including the number of Shares which are to be received upon the exercise thereof, the Corporation shall take any corporate action which may, in the opinion of counsel, be necessary in order that the Corporation has unissued and reserved in its authorized capital and may validly and legally issue as fully paid and non-assessable all the shares (or other securities or property) which the holders of such Warrants are entitled to receive on the full exercise thereof in accordance with the provisions hereof.

4.6Certificate of Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Article 4, deliver a certificate of the Corporation to the Warrant Agent specifying the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate shall be supported by a certificate of the Corporation's Auditor verifying such calculation.

4.9Other Actions

In case the Corporation, after the date hereof, shall take any action affecting the Shares other than action described in Section 4.1, which in the reasonable opinion of the directors of the Corporation would materially affect the rights of Warrantholders, the number of Shares which may be acquired upon exercise of the Warrants shall be adjusted in such manner and at such time, by action of the directors, acting reasonably, in their sole discretion as they may determine to be equitable in the circumstances, provided that no such adjustment will be made unless prior approval of any stock exchange on which the Shares are listed for trading has been obtained, if required by any such stock exchange.

4.10Protection of Warrant Agent

Except as provided in Section 9.1, the Warrant Agent shall not:

4.10.1at any time be under any duty or responsibility to any Warrantholder to determine whether any facts exist which may require any adjustment contemplated by Sections 4.1 and 4.9, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same;

7.MEETINGS OF WARRANTHOLDERS

The notice convening any such meeting may be signed by an appropriate officer of the Warrant Agent or of the Corporation or the person or persons designated by such Warrantholders, as the case may be.

34

7.3Chairman

An individual (who need not be a Warrantholder) designated in writing by the Warrant Agent shall be chairman of the meeting and if no individual is so designated, or if the individual so designated is not present within fifteen (15) minutes from the time fixed for the holding of the meeting, the Warrantholders present in person or by proxy shall choose some individual present to be chairman.

7.4Quorum

Subject to the provisions of Section 7.11, at any meeting of the Warrantholders a quorum shall consist of Warrantholders present in person or by proxy and entitled to purchase at least twenty-five percent (25%) of the aggregate number of Shares which could be acquired pursuant to all the then outstanding Warrants, provided that at least two persons entitled to vote thereat are personally present.

7.6Show of Hands

Every question submitted to a meeting shall be decided in the first place by a majority of the votes given on a show of hands except that votes on an Extraordinary Resolution shall be given in the manner hereinafter provided.

On a show of hands, every person who is present and entitled to vote, whether as a Warrantholder or as proxy for one or more absent Warrantholders, or both, shall have one vote. On a poll, each Warrantholder present in person or represented by a proxy duly appointed by instrument in writing shall be entitled to one vote in respect of each Share of Common Stock which it is entitled to acquire pursuant to the Warrant or Warrants then held or represented by it. A proxy need not be a Warrantholder. In the case of joint holders, any one of them present in person or by proxy at the meeting may vote in the absence of the other or others, but in case more than one of them shall be present in person or by proxy, they shall vote together in respect of Warrants of which they are joint registered holders. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Warrants, if any, held or represented by him.

Save as such regulations may provide, the only persons who shall be recognized at any meeting as a Warrantholder, or be entitled to vote or be present at the meeting in respect thereof (subject to Section 7.9), shall be Warrantholders or their counsel, or proxies of Warrantholders.

9.2.3The Warrant Agent may, before commencing or at any time during the continuance of any such act, action or proceeding, require the Warrantholders, at whose instance it is acting to deposit with the Warrant Agent the Warrants held by them, for which Warrants the Warrant Agent shall issue receipts.

9.2.4Every provision of this Indenture that by its terms relieves the Warrant Agent of liability or entitles it to rely upon any evidence submitted to it is subject to the provisions of Applicable Legislation.

9.2.5No duty shall rest with the Warrant Agent to determine compliance of the transferor or transferee with applicable securities laws. The Warrant Agent shall be entitled to assume that all transfers comply with applicable securities laws.

9.2.6The Warrant Agent shall retain the right not to act and shall not be held liable for refusing to act unless it has received clear and reasonable documentation which complies with the terms of this Indenture, which documentation does not require the exercise of any discretion or independent judgment.

9.3Evidence, Experts and Advisers

9.3.1In addition to the reports, certificates, opinions and other evidence required by this Indenture, the Corporation shall furnish to the Warrant Agent such additional evidence of compliance with any provision hereof, and in such form, as may be prescribed by Applicable Legislation or as the Warrant Agent may reasonably require by written notice to the Corporation.

9.3.3Whenever it is provided in this Indenture or under Applicable Legislation that the Corporation shall deposit with the Warrant Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the truth, accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each and every such case, be conditions precedent to the right of the Corporation to have the Warrant Agent take the action to be based thereon.

9.3.4Proof of the execution of an instrument in writing, including a Warrantholders’ Request, by any Warrantholder may be made by the certificate of a notary public, or other officer with similar powers, that the person signing such instrument acknowledged to it the execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Warrant Agent may consider adequate, and in respect of a corporate Warrantholder, shall include a certificate of incumbency of such Warrantholder together with a certified resolution authorizing the person who signs such instrument to sign such instrument.

9.3.5The Warrant Agent may employ or retain such counsel, accountants, appraisers or other experts or advisers as it may reasonably require for the purpose of determining and discharging its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any counsel, and shall not be responsible for any misconduct or negligence on the part of any such experts or advisers who have been appointed with due care by the Warrant Agent.

9.3.6The Warrant Agent  shall have the right to consult with and obtain advice from legal counsel employed or appointed by it, who may but need not be legal counsel for the  Corporation, or from any expert, in the event of any questions as to any of the provisions hereof or its duties hereunder and it shall incur no liability and it shall be fully protected in acting or not acting in good faith in accordance with any opinion or instruction of such counsel or other expert.  The cost of such services shall be added to and be part of the Warrant Agent's expenses hereunder.

All amounts held by the Warrant Agent pursuant to this Agreement shall be held by the Warrant Agent for the Corporation and the delivery of the funds to the Warrant Agent shall not give rise to a debtor-creditor or other similar relationship. The amounts held by the Warrant Agent pursuant to this Indenture are at the sole risk of the Corporation and, without limiting the generality of the foregoing, the Warrant Agent shall have no responsibility or liability for any diminution of any funds resulting from any deposit made with an Approved Bank pursuant to this section including any losses resulting from a default by the Approved Bank or other credit losses (whether or not resulting from such a default). The parties hereto acknowledge and agree that the Warrant Agent will have acted prudently in depositing the funds at any Approved Bank, and that the Warrant Agent is not required to make any further inquiries in respect of any such bank. The Warrant Agent may hold cash balances constituting part or all of such monies and need not, invest same; the Warrant Agent, its affiliates or a Canadian chartered bank shall not be liable to account for any profit to any parties to this Indenture or to any other person or entity.

46

9.8.4Any Warrant Certificates Authenticated but not delivered by a predecessor warrant agent may be authenticated by the successor warrant agent in the name of the predecessor or successor warrant agent.

9.8.5Upon payment by the Corporation to the retiring Warrant Agent of any and all outstanding fees or charges still properly owing to it, the retiring Warrant Agent shall undertake to transfer all requisite files, inventory and other records to the successor warrant agent upon request of the Corporation.

10.8Shares or Warrants Owned by the Corporation or its Subsidiaries - Certificate to be Provided

For the purpose of disregarding any Warrants owned legally or beneficially by the Corporation or any Subsidiary of the Corporation in Section 7.16, the Corporation shall provide to the Warrant Agent, from time to time, a certificate of the Corporation setting forth as at the date of such certificate:

Should a holder of Warrants exercise any legal, statutory, contractual or other right of withdrawal or rescission that may be available to it, and the holder's funds which were paid on exercise have already been released to the Corporation by the Warrant Agent, the Warrant Agent shall not be responsible for ensuring the exercise is cancelled and a refund is paid back to the holder. In such cases, the holder shall seek a refund directly from the Corporation and subsequently, the Corporation, upon surrender to the Corporation or the Warrant Agent of any underlying shares that may have been issued, or such other procedure as agreed to by the parties hereto, shall instruct the Warrant Agent in writing, to cancel the exercise transaction and any such underlying shares on the register, which may have already been issued upon the Warrant exercise. In the event that any payment is received from the Corporation by virtue of the holder being a shareholder for such Warrants that were subsequently rescinded, such payment must be returned to the Corporation by such holder. The Warrant Agent shall not be under any duty or obligation to take any steps to ensure or enforce that the funds are returned pursuant to this section, nor shall the Warrant Agent be in any other way responsible in the event that any payment is not delivered or received pursuant to this section. Notwithstanding the foregoing, in the event that the Corporation provides the refund to the Warrant Agent for distribution to the holder, the Warrant Agent shall return such funds to the holder as soon as reasonably practicable, and in so doing, the Warrant Agent shall incur no liability with respect to the delivery or non-delivery of any such funds.

10.11.2The Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Warrant Agent, in its sole judgment, acting reasonably, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering, anti-terrorist or economic sanctions legislation, regulation or guideline.

WARRANTS
Exercisable to Acquire
Shares
of
IntelGenx Technologies Corp.
(Incorporated under the laws of Delaware)

THIS IS TO CERTIFY THAT, for value received, ● (the "Holder") is the registered holder of the number of Warrants of IntelGenx Technologies Corp. (the "Corporation") specified above and, for each Warrant held, is thereby entitled to be issued, subject to adjustment and except as otherwise described herein, one fully paid and non-assessable share of common stock of the Corporation (each, a "Common Share") and subject to the limitation referred to below by surrendering to TSX Trust Company (the "Warrant Agent") at its principal transfer offices in Toronto, Ontario during the exercise period hereinafter referred to, a certified cheque or bank draft made payable to the Corporation in the amount of the Exercise Price as hereinafter determined in respect of each Common Share to be issued, this Warrant Certificate and a notice of exercise in the form set forth in Appendix 1 annexed hereto duly completed and executed, provided notice is also sent to the Corporation by delivering to it a copy of such documents.

Capitalized terms which are not otherwise defined herein shall have the same meaning as in the Warrant indenture (which indenture, together with all instruments supplemental or ancillary thereto, is herein referred to as the "Warrant Indenture") dated February 11, 2020 between the Corporation and the Warrant Agent.

55

Surrender of this Warrant Certificate will be deemed to have been effected only on personal delivery thereof to, or, if sent by mail or other means of transmission, on actual receipt thereof by, the Warrant Agent at the office specified above.

This Warrant Certificate evidences Warrants of the Corporation issued or issuable under the provisions of the Warrant Indenture. Reference is made to the Warrant Indenture for particulars of the rights of the holders of the Warrants and of the Corporation and of the Warrant Agent in respect thereof and of the terms and conditions upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth in full, to all of which the holder, by acceptance hereof, assents. To the extent of any inconsistency between the terms of the Warrant Indenture and the terms of this Warrant Certificate, the terms of the Warrant Indenture shall prevail. The Corporation will furnish to the holder, on request and upon payment of a reasonable charge for photocopying and postage, a copy of the Warrant Indenture.

The Warrants evidenced by this Warrant Certificate may be exercised by the holder (including, if applicable, any agent under any power of attorney granted by such holder) at any time until 5:00 pm (Toronto Time) on February 11, 2023 (the "Expiry Time").

On and after the date of any exercise of the Warrants evidenced by this Warrant Certificate, the holder will have no rights hereunder except to receive certificates representing the Shares thereby issued to him upon delivery of a certified cheque or bank draft payable to the Corporation in respect of each Common Share to be issued in the amount of $0.75 the "Exercise Price"), this Warrant Certificate and a duly completed notice of exercise as set out in Appendix  1" thereto to the Warrant Agent at its principal offices in Toronto, Ontario. After the Expiry Time, all rights under any unexercised Warrant evidenced hereby will wholly cease and terminate and this Warrant Certificate will be void.

The Corporation will not be obligated to issue any fraction of a Common Share on the exercise of any Warrant. To the extent that a holder of Warrants would otherwise have been entitled to receive, on the exercise of Warrants, a fraction of a Common Share, such right may only be exercised in respect of such fraction in connection with another Warrant or Warrants which in the aggregate entitle the holder to receive a whole number of Shares. If a Warrantholder is not able to combine Warrants so as to be entitled to acquire a whole number of Shares, the number of Shares which such Warrantholder is entitled to receive shall be rounded down to the prior whole number, as applicable.

The Warrant Indenture provides for adjustments to the number of Shares issuable and to the Exercise Price in certain events set forth therein.

The Warrant Indenture contains provisions making binding on all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders held in accordance with such provisions and instruments in writing signed by holders of a specified majority of all outstanding Warrants.

On presentation at the principal offices of the Warrant Agent in Toronto Ontario, subject to the provisions of the Warrant Indenture and on compliance with the reasonable requirements of the Warrant Agent, one or more Warrant Certificates may be exchanged for one or more Warrant Certificates of different denominations evidencing in the aggregate the same number of Warrants as the Warrant Certificate or Warrant Certificates being exchanged.

56

The Warrants evidenced by this Warrant Certificate may only be transferred, upon compliance with the conditions prescribed in the Warrant Indenture, on the register of transfers to be kept at the principal offices of the Warrant Agent in Toronto, Ontario by the holder or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent, and, upon compliance with such requirements and such other reasonable requirements as the Warrant Agent may prescribe, such transfer will be duly noted on such register of transfers by the Warrant Agent. Notwithstanding the foregoing, the Corporation will be entitled, and may direct the Warrant Agent, to refuse to record any transfer of any Warrant on such register if such transfer would constitute a violation of the securities laws of any jurisdiction or require the Corporation to qualify the Shares for distribution in any jurisdiction other than the Qualifying Jurisdictions.

No Shares will be issued pursuant to any exercise of any Warrant if the issue of such security would constitute a violation of the securities laws of any applicable jurisdiction.

The Warrants evidenced hereby shall not be exercised by any person during any time that no registration statement under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), registering the Common Shares issuable upon the exercise of the Warrants evidenced hereby is effective, unless an exemption from the registration requirements of the U.S. Securities Act is available and such holder provides evidence of the availability of such exemption satisfactory to the Corporation.

The holding of this Warrant Certificate will not constitute the holder a shareholder of the Corporation or entitle such holder to any right or interest in respect thereof except as otherwise provided in the Warrant Indenture.

This Warrant Certificate will not be valid for any purpose until it has been authenticated by or on behalf of the Warrant Agent for the time being under the Warrant Indenture. Time will be of the essence hereof.

THE WARRANTS REPRESENTED BY THIS CERTIFICATE WILL BE VOID AND OF NO VALUE UNLESS EXERCISED PRIOR TO 5:00 P.M. (TORONTO TIME) ON OR BEFORE FEBRUARY 11, 2023, IN ACCORDANCE WITH THE PROVISIONS OF THE WARRANT INDENTURE.
