2.4
Warrantholder Not a Shareholder
 
The Warrant shall not constitute the holder a shareholder of the Corporation, nor entitle it to any right or interest in respect thereof except as may be expressly provided in the Warrant. The Corporation may deem and treat the holder of the Warrant as the absolute owner thereof for all purposes and the Corporation shall not be affected by any notice to the contrary.

2.5
Register of Warrants
 
At all times while Warrants are outstanding, the Corporation shall maintain a register of all holders of Warrants on which shall be entered the names, latest known addresses of all holders and if available, the telecopier numbers of such holders and particulars of the Warrants held by them and a register of transfers in which shall be entered the particulars of all transfers of Warrants, such registers to be kept by and at the office of the Corporation.
 
2.6
Transfer
 
Warrants may only be transferred on the register of the Corporation by the holder thereof or its legal representatives or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Corporation in accordance with applicable laws. The Warrants and the Common Shares issuable thereunder are and may continue to be subject to resale restrictions and hold periods, and holders should consult their legal advisors in respect of the same. Such transfer will be effected upon surrender to the Corporation of this Warrant Certificate for cancellation and the duly completed and executed Transfer Form attached hereto as Appendix 1 and upon compliance, to the reasonable satisfaction of the Corporation, with:

(a)
the conditions herein;
 
(b)
such reasonable requirements as the Corporation may require; and
 
all applicable securities legislation and requirements of regulatory authorities and all stock exchanges upon which the Common Shares are listed from time to time, as applicable.

ARTICLE 3
 
EXERCISE OF THE WARRANT

3.1
Method of Exercise of The Warrant
 
The holder may exercise the right hereby conferred on the holder to acquire Common Shares (subject to the provisions of this Article 3) by:
 
(a)
duly completing and executing the Warrant Exercise Form attached hereto as Appendix 2; and
 
(b)
surrendering this certificate, together with the holder’s certified cheque or a bank draft, money order or wire transfer in the full amount of the total aggregate Exercise Price of the Common Shares being purchased, together with the duly completed and executed Warrant Exercise Form, to the Corporation at its offices,
 
at any time up until the Time of Expiry. This Warrant Certificate shall be deemed to be surrendered only upon personal delivery thereof to, or if sent by mail or other means of transmission, upon actual receipt thereof by, the Corporation at its offices.

5


3.2
Effect of Exercise of the Warrant
 
(a)
Upon surrender and payment as aforesaid the Common Shares so subscribed for shall be issued as fully paid and non-assessable shares, free from all liens, charges and encumbrances and the holder shall become the holder of record of such Common Shares on the date of such surrender and payment;
 
(b)
Within ten (10) business days after surrender and payment as aforesaid, the Corporation shall forthwith cause the issuance of and mail to the holder a certificate for the Common Shares purchased as aforesaid;
 
(c)
Notwithstanding anything herein contained including any adjustment provided for in Article 4, the Corporation shall not be required, upon the exercise of any Warrants, to issue fractions of Common Shares or to distribute certificates which evidence fractional Common Shares. Any fractional Common Shares that would otherwise be issuable upon the exercise of Warrants shall be cancelled by the Corporation without compensation to the holder thereof; and
 
(d)
Notwithstanding anything herein contained, no Common Shares will be issued pursuant to the exercise of any Warrant if the issuance of such Common Shares would constitute a violation of the securities laws of any applicable jurisdiction or the requirements of any applicable stock exchange, and without limiting the generality of the foregoing, in the event that any of the Warrants are exercised prior to expiry of any hold period or other resale restriction placed thereon by such laws or requirements, the certificates evidencing the Common Shares thereby issued will bear such legend as is required under applicable securities laws and that, in the opinion of legal counsel to the Corporation, is necessary in order to avoid a violation of any such laws or requirements.
 
3.3
Privilege to Exercise
 
Notwithstanding paragraph 3.2 above, any Common Shares which are obtained as a result of exercise of the Warrant will be held by the holder and will not be sold, transferred or assigned in any way until the product OvaRex® MAb has been approved for sale by the EMEA in a European country which is one of the Territories stipulated in the License Agreement.
 
3.4
Subscription for Less than Entitlement
 
The holder may subscribe for and purchase a number of Common Shares less than the number which it is entitled to purchase pursuant to the surrendered Warrant Certificate. In the event of any purchase of a number of Common Shares less than the number which can be purchased pursuant to the Warrant Certificate, the Corporation shall forthwith issue and deliver to the holder a new Warrant Certificate containing the same terms and conditions as disclosed herein to purchase that number of Common Shares with respect to which such partial exercise did not apply.

6


3.5
Resale Restrictions
 
Unless permitted under securities legislation, the holder of the Warrants and Common Shares issued upon their exercise shall not trade such securities before January 31, 2007.
 
3.6
Expiration of the Warrant
 
After the Time of Expiry all rights hereunder shall wholly cease and terminate and the Warrant Certificate and the Warrants shall be void and of no further force and effect.

ARTICLE 4
 
ADJUSTMENTS

4.1
Adjustments
 
The acquisition rights in effect at any date attaching to the Warrants shall be subject to adjustment from time to time as follows:

(a)
If and whenever at any time after the date hereof and prior to the Time of Expiry, any adjustment in the Exercise Price or in the calculation thereof pursuant to Section 4.2 shall occur as a result of:
 
(i) an event referred to in subsection 4.2(a);
 
 
(ii)
the fixing by the Corporation of a record date for an event referred to in subsection 4.2(b); or
 
 
(iii)
the fixing by the Corporation of a record date for an event referred to in subsection 4.2(c) if such event constitutes the issue or distribution to the holders of all or substantially all of its outstanding Common Shares of:
 
 
(A)
Common Shares, or
 
 
(B)
securities exchangeable for or convertible into Common Shares at less than the Current Market Price of the Common Shares on such record date, or
 
 
(C)
rights, options or warrants to acquire Common Shares at an exercise, exchange or conversion price per Common Share less than the Current Market Price of the Common Shares on such record date, the number of Common Shares obtainable upon the subsequent exercise of the Warrant shall be adjusted simultaneously with the adjustment in the Exercise Price pursuant to Section 4.2 by multiplying the number of Common Shares theretofore obtainable on the exercise thereof immediately prior to such adjustment by a fraction of which the numerator shall be the total number of Common Shares outstanding immediately after such date and the denominator shall be the total number of Common Shares outstanding immediately prior to such date. To the extent that any adjustment in subscription rights occurs pursuant to this subsection 4.1(a) as a result of the distribution of securities convertible into or exchangeable for Common Shares referred to in subsection 4.2(a) or as a result of the fixing by the Corporation of a record date for the distribution of rights, options or warrants referred to in subsection 4.2(b), the number of Common Shares purchasable upon exercise of a Warrant shall be readjusted immediately after the expiration of any relevant exchange, conversion or exercise right to the number of Common Shares which would be purchasable based upon the number of Common Shares actually issued and remaining issuable immediately after such expiration, and shall be further readjusted in such manner upon expiration of any further such right. To the extent that any such adjustment in subscription rights occurs pursuant to this subsection 4.1(a) as a result of the fixing by the Corporation of a record date for the distribution referred to in subsection 4.2(c) of rights, options or warrants or exchangeable or convertible securities, the number of Common Shares purchasable upon exercise of a Warrant shall be readjusted immediately after the expiration of any relevant exchange, conversion or exercise right to the number which would be purchasable pursuant to this subsection 4.1(a) if the fair market value of such rights, options or warrants or other exchangeable or convertible securities had been determined for the purposes of the adjustment pursuant to this subsection 4.1(a) on the basis of the number of Common Shares issued and remaining issuable immediately after such expiration, and shall be further readjusted in such manner upon expiration of any further right.
 
 

7

 

 
(b)
If and whenever at any time after the date hereof and prior to the Time of Expiry there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in subsection 4.2(a) or a consolidation, amalgamation or merger of the Corporation (including, without limitation, by way of plan of arrangement) 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, any Warrantholder who has not exercised his right of acquisition prior to the effective date of such reclassification, reorganization, consolidation, amalgamation, merger, sale or conveyance, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of Common Shares then sought to be acquired by it, the kind and number of shares or other securities or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such reclassification, reorganization, consolidation, amalgamation or merger, or to which such sale or conveyance may be made, as the case may be, that such holder would have been entitled to receive as a result of such reclassification, reorganization, consolidation, amalgamation, 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 Common Shares to which the holder was theretofore entitled upon exercise. If determined appropriate by the board of directors of the Corporation to give effect to or to evidence the provisions of this subsection 4.1(b), 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, reorganization, consolidation, amalgamation, merger, sale or conveyance, enter into an agreement or new Warrant Certificate which shall provide, to the extent possible, for the application of the provisions set forth in this Warrant Certificate with respect to the rights and interests thereafter of the Warrantholder to the end that the provisions set forth in this Warrant 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 and upon entering into such new Warrant Certificate or agreement, the Corporation shall cease to have any obligations (including the obligation to issue any Common Shares) hereunder and the holder shall cease to have any rights hereunder. Any Warrant Certificate or agreement entered into pursuant to the provisions of this subsection 4.1(b) shall be an agreement entered into pursuant to the provisions of Article 6. Any Warrant Certificate or agreement entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Article 4 and which shall apply to successive reclassifications, reorganizations, consolidations, amalgamations, mergers, sales or conveyances.
 

8


 
4.2
Adjustment of Exercise Price
 
The Exercise Price in effect at any date attaching to the Warrants shall be subject to adjustment from time to time as follows:

(a)
If and whenever after the date hereof and at any time prior to the Time of Expiry, the Corporation shall:
 
(i) subdivide, divide or change its outstanding Common Shares into a greater number of Common Shares;
 
(ii) consolidate, reduce or combine its outstanding Common Shares into a lesser number of Common Shares;
 
(iii) make any distribution, other than by way of Dividend Paid in the Ordinary Course, to the holders of all or substantially all of the outstanding Common Shares payable in Common Shares;
 
 
the Exercise Price in effect on the effective date of such events referred to in subsections 4.2(a)(i), 4.2(a)(ii), or 4.2(a)(iii) shall be adjusted to equal the price determined by multiplying the Exercise Price in effect immediately prior to such effective date by a fraction of which the numerator shall be the total number of Common Shares outstanding immediately prior to such date and the denominator shall be the total number of Common Shares immediately after such date. Such adjustment shall be made successively whenever any event referred to in this subsection 4.2(a) shall occur.
 
(b)
If and whenever at any time after the date hereof, the Corporation shall fix a record date which is prior to the Time of Expiry for the issue of rights, options or warrants to all or substantially all the holders of outstanding Common Shares under which such holders are entitled during a period expiring not more than sixty (60) days after the record date for such issue to subscribe for or purchase Common Shares, or securities convertible into or exchangeable for Common Shares, at a price per Common Share or having a conversion or exchange price per Common Share less than the Current Market Price per Common Share on such record date, 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 Common Shares outstanding on such record date plus a number of Common Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase, or the aggregate conversion or exchange price of the convertible securities so offered, by such Current Market Price per Common Share, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total number of additional Common Shares offered for subscription or purchase (or into which the convertible securities so offered are convertible or exchangeable). If by the terms of the rights, options or warrants referred to in this subsection 4.2(b), there is more than one purchase, conversion or exchange price per Common Share, the aggregate price of the total number of additional Common Shares offered for subscription or purchase, or the aggregate conversion or exchange price of the convertible securities so offered, shall be calculated for purposes of the adjustment on the basis of the lowest purchase, conversion or exchange price per Common Share, as the case may be. Any Common Shares owned by or held for the account of the Corporation or any subsidiary of the Corporation shall be deemed not to be outstanding for the purpose of any such computation. To the extent that any adjustment in Exercise Price occurs pursuant to this subsection 4.2(b) as a result of the fixing by the Corporation of a record date for the distribution of rights, options or warrants referred to in this subsection 4.2(b), the Exercise Price shall be readjusted immediately after the expiration of any relevant exchange, conversion or exercise right to the Exercise Price which would then be in effect based upon the number of Common Shares actually issued and remaining issuable after such expiration, and shall be further readjusted in such manner upon expiration of any further such right.
 

9

 
(c)
If and whenever at any time prior to the Time of Expiry, the Corporation shall fix a record date which is prior to the Time of Expiry for the issue or distribution to all or substantially all the holders of its outstanding Common Shares of:
 
(i) shares of any class other than Common Shares (excluding Dividends Paid in the Ordinary Course);
 
(ii) rights, options or warrants (excluding those referred to in subsection 4.2(b));
 
(iii) evidences of its indebtedness; or
 
(iv) any other property or assets (excluding Dividends Paid in the Ordinary Course);
 

10

 
then, and 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 Common Shares outstanding on such record date multiplied by the Current Market Price on such record date, less the aggregate fair market value (as determined by the Corporation, which determination shall be conclusive) of such shares, rights, options, warrants, evidences of indebtedness or assets so issued or distributed, and of which the denominator shall be the total number of Common Shares outstanding on such record date multiplied by such Current Market Price, and any Common Shares owned by or held for the account of the Corporation or any subsidiary of the Corporation 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, and to the extent that such distribution is not so made, the Exercise Price shall then 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, rights, options, warrants, evidences of indebtedness or assets actually distributed, as the case may be.
4.3
General Adjustments
 
(a)
If necessary, appropriate adjustments shall be made in the application of the provisions set forth in this Article 4 with respect to the rights and interests thereafter of the holders of Warrants to the end that the provisions set forth in this Article 4 shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other securities or property thereafter deliverable upon the exercise of any Warrant. Any such adjustments shall be made by and set forth in an amendment to this Warrant Certificate hereto approved by the directors of the Corporation and shall for all purposes conclusively be deemed to be an appropriate adjustment.
 
(b)
If any case in which this Article 4 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 Common 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 Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the relevant date of exercise or such later date as such holder would, but for the provisions of this subsection 4.3(b), have become the holder of record of such additional Common Shares as a result of the exercise of the Warrants.
 

11


(c)
No adjustment in the Exercise Price or in the number of shares to be issued pursuant to the exercise of the Warrants shall be required unless such adjustment would result in a change of at least 1% in the Exercise Price then in effect or unless the number of shares to be issued would change by at least 1/100th of a share, provided, however, that any adjustments which, except for the provisions of this subsection 4.3(c) would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.
 
(d)
The adjustments provided for in this Article 4 in the Exercise Price and in the number and classes of shares which are to be received on the exercise of Warrants are cumulative. After any adjustment pursuant to this Section, the term "Common Shares" where used in this Warrant shall be interpreted to mean the shares or other securities or property of the Corporation which, as a result of all prior adjustments pursuant to this Section, the Warrantholder is entitled to receive upon the exercise of his Warrant, and the number of Common Shares indicated in any subscription made pursuant to a Warrant shall be interpreted to mean the number and kind of securities or property which, as a result of all prior adjustments pursuant to this Article 4, a Warrantholder is entitled to receive upon the full exercise of a Warrant entitling the holder thereof to purchase the number of Common Shares so indicated.
 
(e)
All securities and property which a Warrantholder is at the time in question entitled to receive on the full exercise of his Warrant, whether or not as a result of adjustments made pursuant to this Section, shall, for the purposes of the interpretation of this Warrant be deemed to be securities and property which such Warrantholder is entitled to purchase pursuant to such Warrant.
 
4.4
Notice of Adjustment
 
Whenever the number of Common Shares purchasable upon the exercise of each Warrant or the Exercise Price of such Common Shares is adjusted, as herein provided, the Corporation shall promptly send to the Warrantholder by first class mail, postage prepaid, notice of such adjustment or adjustments.
 
ARTICLE 5

1.
If the Warrant Exercise Form indicates that Common Shares are to be issued to a person or persons other than the registered holder of the certificate, the signature of such holder of the Warrant Exercise Form must be guaranteed by an authorized officer of a chartered bank, trust corporation or an investment dealer who is a member of a recognized stock exchange.
 
2.
If the Warrant Exercise Form is signed by a trustee, executor, administrator, curator, guardian, attorney, officer of a corporation or any person acting in a judiciary or representative capacity, the certificate must be accompanied by evidence of authority to sign satisfactory to the Corporation.
 
3.
If the registered Holder exercises its right to receive Common Shares prior to expiry of any hold period or other resale restriction placed on the Warrants by the securities laws of any applicable jurisdiction or the requirements of any applicable stock exchange, the certificates evidencing the Common Shares thereby issued will bear such legend as is required under applicable securities laws and that, in the opinion of legal counsel to the Corporation, be necessary in order to avoid a violation of any such laws or requirements.
