(d) Refusal of Registration: The Corporation will be entitled, and may direct the Warrant Agent, to refuse to recognize any transfer, or enter the name of any transferee, of any Warrant on the registers referred to in subsection 2.08(a) hereof, if such transfer would constitute a violation of the securities laws of any jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction. In particular, prior to the Registration Statement becoming effective, none of the Warrants and none of the Common Shares issuable on the exchange of the Warrants have been registered under the 1933 Act and such securities may not be offered or sold to a U.S. Person (except a Qualified U.S. Entity), a Person in the United States or a Person for the account or benefit of a U.S. Person (except a Qualified U.S. Entity), or a Person in the United States absent an exemption from the registration provisions of the 1933 Act.

(g) Location of Registers: The Corporation may at any time and from time to time change the place at which the registers referred to in subsection 2.08(a) hereof are kept, cause branch registers of holders or transfers to be kept at other places and close such branch registers or change the place at which such branch registers are kept, in each case subject

The Warrant Agent shall be entitled to process all preferred transfers and exercises of Warrants upon the presumption that such transfers or exercises are permissible pursuant to all Applicable Legislation and regulatory requirements and the terms of the Indenture and the related Warrant Certificates in the absence of prima facie evidence to the contrary. The Warrant Agent may assume for the purposes of this Indenture that the address on the register of Warrantholders of any Warrantholder is the actual address of such Warrantholder and is also determinative of the residency of such Warrantholder and that the address of any transferee to whom any Warrants or Common Shares or other securities issuable upon the exercise of any Warrants are to be registered, as shown on the transfer document, is the actual address of the transferee and is also determinative of the residency of the transferee.

(a) Owner: The Corporation and the Warrant Agent may deem and treat the person in whose name any Warrant is registered as the absolute owner of such Warrant for all purposes, and such person will for all purposes of this Indenture be and be deemed to be the absolute owner thereof, and the Corporation and the Warrant Agent will not be affected by any notice or knowledge to the contrary except as required by statute or by order of a court of competent jurisdiction.

(b) Rights of Registered Holder: The registered holder of any Warrant will be entitled to the rights evidenced thereby free from all equities and rights of set-off or counterclaim between the Corporation and the original or any intermediate holder thereof and all persons may act accordingly, and the issue and delivery to any such registered holder of the Common Shares issuable pursuant thereto will be a good discharge to the Corporation and the Warrant Agent therefor and neither the Corporation nor the Warrant Agent will be bound to inquire into the title of any such registered holder.

(a) Exercise: Subject to subsection 4.01(c) hereof, the holder of any Warrant may exercise the right thereby conferred on such holder to subscribe for and purchase Common Shares by surrendering, after the date of issue of the Warrant but prior to the Time of Expiry, to the Warrant Agent at the place specified in subsection 4.01(h) hereof or any other place or places that may be designated by the Corporation with the approval of the Warrant Agent:

(c) Exercise Mechanics if Registration Statement Not Effective: Notwithstanding any provision to the contrary contained in this Indenture, if the Corporation advises the Warrant Agent in writing that the issuance of Common Shares upon the exercise of Warrants requires the maintenance of an effective Registration Statement, with respect to such Common Shares under the 1933 Act, in no event shall such Common Shares be issued unless the Common Shares are registered under the 1933 Act pursuant to an effective Registration Statement; provided, however, that if the Registration Statement ceases to be effective, prior to the Time of Expiry Time and for so long as the Registration Statement is not effective, subject to applicable law, a holder of any Warrant may only exercise the right to purchase Common Shares issuable upon the exercise of the Warrants the circumstances noted below:

(e) Suspensions of Registration Statement, etc,…: If any Common Shares issuable upon the exercise of Warrants require the maintenance of a current Registration Statement, with respect to such Common Shares under the 1933 Act, the Corporation shall have the authority to suspend the exercise of any or all Warrants while such registration statement is not current. Similarly, a Warrantholder residing in a state where a required registration or governmental approval of issuance of the Common Shares is not in effect as of or has not been obtained within a reasonable time after the surrender date of the Warrant Certificate for exercise shall not be entitled to exercise Warrants, unless in the opinion of counsel to the Corporation such registration or approval in such state shall not be required or the Corporation otherwise authorizes the issuance. In such event, the Warrantholder shall be entitled to transfer the Warrants to others, but only prior to the Expiry Date for the Warrants being transferred. If no Registration Statement is effective at any time when any Warrant is exercised, such Warrantholder shall be notified forthwith by the Transfer Agent that such Warrantholder is entitled, at his or her option, to exercise the Warrant only in accordance with the conditions set forth in Sections 4.01(c)(i) and (ii) and upon delivery of a Warrant Exercise Certification (in the form attached hereto as Schedule B) to the Warrant Agent and the Corporation.

(f) No Additional Cash Payment for Warrants: Notwithstanding that the Corporation may not have maintained a current Registration Statement in respect of Common Shares under the 1933 Act, no Warrantholder (whether a U.S. Purchaser or otherwise) shall have any right to receive, and the Corporation shall be under no obligation to pay to any Warrantholder (whether a U.S. Purchaser or otherwise), any cash amount or other consideration or compensation upon exercise of the Warrants, other than as expressly provided by this Indenture, and the Corporation shall not be under any obligation to redeem or otherwise purchase any Warrants in any circumstance; provided, however, that nothing in this clause shall limit or restrict any remedies of the Transfer Agent or any Warrantholder or Warrantholders in respect of a breach by the Corporation of a representation, warranty or covenant hereunder, including without limitation the covenant in Section 7.01(j) of this Indenture.

(g) Subscription Form Completion: Any subscription form referred to in subsection 4.01(a) hereof shall be signed by the Warrantholder, or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Warrant Agent, acting reasonably, and shall specify (A) the number of Warrants that the holder desires to exercise, such number being not more than the number which the holder is entitled to exercise pursuant to the Warrant Certificate surrendered, (B) the person or persons in whose name or names Common Shares issuable upon such exercise are to be issued, (C) the address or addresses of such person or persons, or the office of the Warrant Agent at which the Warrant Certificate was surrendered and the certificates representing such Common

16 Shares are to be sent, and (D) the number of Common Shares to be issued to each such person if more than one is so specified. If any of the Common Shares subscribed for are to be issued to a person or persons other than the Warrantholder, the Warrantholder shall pay to the Warrant Agent all applicable transfer or similar taxes, if any, and, the Corporation and the Warrant Agent shall not be required to issue or deliver certificates representing Common Shares unless or until such Warrantholder shall have paid to the Warrant Agent the amount of such tax, if any, or shall have established to the satisfaction of the Warrant Agent that such tax has been paid or that no tax is due.

(h) Places for Exercise: The Corporation has designated the Warrant Agent, at its principal office in the City of Toronto, Ontario, as the place at which the Warrants may be exercised. The Corporation will give notice to the Warrantholders pursuant to article twelve hereof of the location of any other place appointed by the Corporation and approved by the Warrant Agent and of the change in the location of any new or existing place where Warrants may be exercised.

(i) Accounting to Corporation: The Warrant Agent shall as soon as practicable account to the Transfer Agent and the Corporation with respect to Warrants exercised. 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 in trust for, the Corporation. Within five Business Days of receipt thereof the Warrant Agent shall forward to the Corporation (or to an account or accounts of the Corporation with a bank or trust company designated in writing by the Corporation for that purpose) all monies received through the exercise of Warrants pursuant to this article four.

(j) Record of Exercise: The Warrant Agent shall record the particulars of the Warrants exercised for Common Shares which particulars shall include the names and addresses of the persons who become holders of Common Shares, if any, on exercise, the number of Common Shares issued, the Exercise Date and the Exercise Price. Within five Business Days of each Exercise Date, the Warrant Agent shall provide such particulars in writing to the Corporation and the Transfer Agent.

(a) Effect of Exercise: Upon compliance by the holder of any Warrant Certificate with the provisions of section 4.01 hereof, but subject to the provisions of subsection Section 2.02(d) hereof, the number of Common Shares subscribed for and purchased shall be deemed to have been issued and the person or persons to whom such Common Shares are to be issued shall be deemed to have become the holder or holders of record of such Common Shares on the Exercise Date thereof unless the transfer books of the Corporation shall be closed on such date, in which case the Common Shares subscribed for and purchased shall be deemed to have been issued, and such person or persons shall be deemed to have become the holder or holders of record of such Common Shares on the date on which such transfer books are reopened but such Common Shares shall be issued at the Exercise Price in effect on the Exercise Date.

(b) Issue of Share Certificates: As soon as practicable, and in any event no later than the third Business Day on which the transfer books of the Corporation have been opened after the exercise of a Warrant as aforesaid, the Corporation shall forthwith (A) cause to be mailed to the person or persons in whose name or names the Common Shares so

(f) Adjustments Prior to Effective Date: Notwithstanding any other provisions hereof, in the event that, at any time prior to the Effective Date, there shall have occurred one or more events which, if any Warrant was outstanding, would require an adjustment or adjustments thereto or to the exercise price thereof in accordance with the provisions hereof, then, notwithstanding anything to the contrary herein and notwithstanding that no Warrants may be outstanding at the applicable time under this Indenture, at the time of the issue of Warrants hereunder the same adjustment or adjustments in accordance with the adjustment provisions hereof shall be made to such Warrants, mutatis mutandis, as if such Warrants were outstanding and governed by the provisions hereof upon the occurrence of such event or events.

(a) Successive Adjustments: Any adjustment made pursuant to section 5.01 hereof shall be cumulative and made successively whenever an event referred to therein shall occur, subject to the following subsections of this section 5.02.

(b) Minimum Adjustments: No adjustment in the Exercise Price shall be required unless such adjustment would result in a change of at least 1% in the Exercise Price and no adjustment shall be made in the number of Common Shares purchasable upon exercise of a Warrant unless it would result in a change of at least one one-hundredth of a Common Share; provided, however, that any adjustments which, except for the provisions of this subsection 5.02(b), would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment, and provided further that in no event shall the Corporation be obligated to issue fractional Common Shares upon exercise of Warrants.

(d) No Adjustment for Certain Events: No adjustment in the Exercise Price or in the number of Common Shares purchasable upon the exercise of Warrants shall be made pursuant to section 5.01 hereof in respect of the issue from time to time of Common Shares pursuant to this Indenture or pursuant to any stock option, stock purchase or stock bonus plan in

23 effect from time to time for directors, officers or employees of the Corporation and/or any Subsidiary of the Corporation and any such issue, and any grant of options in connection therewith, shall be deemed not to be a Common Share Reorganization, a Rights Offering nor any other event described in section 5.01 hereof.

(e) Other Actions: If at any time after the Effective Date but prior to the Expiry Date the Corporation shall take any action affecting the Common Shares, other than an action described in section 5.01 hereof, which in the opinion of the Directors acting in good faith would materially affect the rights of Warrantholders, either or both the Exercise Price and the number of Common Shares purchasable upon exercise of Warrants shall be adjusted in such manner and at such time by action by the Directors, acting in good faith in their sole discretion, but subject to the prior written consent, if required, of any stock exchange upon which the Common Shares or Warrants may be listed, as may be equitable in the circumstances. Failure of the taking of action by the Directors so as to provide for an adjustment prior to the effective date of any action by the Corporation affecting the Common Shares shall be deemed to be conclusive evidence that the Directors have determined that it is equitable to make no adjustment in the circumstances.

(f) Abandonment of Event: If the Corporation shall set a record date to determine the holders of Common Shares for the purpose of entitling such holders to receive any dividend or distribution or any subscription or purchase rights and shall, thereafter and before the distribution to such Shareholders of any such dividend, distribution or subscription or purchase rights, legally abandon its plan to pay or deliver such dividend, distribution or subscription or purchase rights, then no adjustment in the Exercise Price or the number of Common Shares purchasable upon exercise of any Warrant shall be required by reason of the setting of such record date.

(g) Deemed Record Date: In the absence of a resolution of the Directors fixing a record date for a Common Share Reorganization, a Rights Offering or a Special Distribution, the Corporation shall be deemed to have fixed as the record date therefor the earlier of the date on which holders of record of Common Shares are determined for the purpose of participating in the Common Share Reorganization, Rights Offering or Special Distribution and the date on which the Common Share Reorganization, Rights Offering or Special Distribution becomes effective.

(h) Disputes: If a dispute shall at any time arise with respect to adjustments of the Exercise Price or the number of Common Shares purchasable upon exercise of Warrants, such disputes shall be conclusively determined by the Corporation’s Auditors or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by action by the Directors and acceptable to the Warrant Agent and any such determination shall be conclusive evidence of the correctness of any adjustment made under section 5.01 hereof and shall be binding upon the Corporation, the Warrant Agent and the Warrantholders. Such auditors or accountants shall be provided access to all necessary records of the Corporation for the purpose of such determination. In the event any determination is made, the Corporation shall deliver a Certificate of the Corporation to the Warrant Agent describing such determination.

(i) Corporate Affairs: As a condition precedent to the taking of any action which would require any adjustment in any of the subscription rights pursuant to the Warrants, including the Exercise Price and the number or class of shares or other securities which are to be received upon the exercise thereof, the Corporation shall take any action which

24 may, in the opinion of Counsel, be necessary in order that the Corporation may validly and legally issue as fully paid and non-assessable all the shares or other securities which all holders of Warrants are entitled to receive in accordance with the provisions thereof.

(a) issuing to the holder of any Warrant, to the extent that Warrants are exercised after such record date and before the occurrence of such event, the additional Common Shares or other securities issuable upon such exercise by reason of the adjustment required by such event; and

(b) delivering to such holder any distribution declared with respect to such additional Common Shares or other securities after such exercise date and before such event;

(a) Notice of Effective or Record Date: At least ten days prior to the effective date or record date, as the case may be, of any event which requires or might require an adjustment in any of the subscription rights pursuant to any of the Warrants, including the Exercise Price and the number of Common Shares which are purchasable upon the exercise thereof, the Corporation shall:

(b) Adjustment Not Determinable: In case any adjustment for which a notice pursuant to subsection 5.04(a) hereof has been given is not then determinable, the Corporation shall promptly after such adjustment is determinable:

(c) Duty of Warrant Agent: Subject to subsection 11.02(a) hereof, the Warrant Agent shall not:

26 (b) the Corporation will cause certificates representing the Common Shares, if any, from time to time subscribed and paid for pursuant to the exercise of Warrants to be issued and delivered in accordance with the terms hereof;

(e) the Corporation will give to the Warrantholders, in the manner provided in article twelve hereof, and to the Warrant Agent, notice of its intention to fix a record date, or effective date, as the case may be, for any event referred to in section 5.01 hereof which may give rise to an adjustment in the Exercise Price or in the number of Common Shares purchasable upon the exercise of Warrants and, in each case, such notice shall specify the particulars of such event and the record date, or the effective date, for such event; provided that the Corporation shall only be required to specify in such notice such particulars of such event as shall have been fixed and determined on the date on which such notice is given, and such notice shall be given in each case not less than 21 days prior to the applicable record date or effective date, as the case may be;

(f) the Corporation will not close its transfer books nor take any other action which might deprive a Warrantholder of the opportunity of exercising the right of purchase pursuant to the Warrants held by such person during the period of 21 days after the giving of a notice required by this section 7.01 or unduly restrict such opportunity;

(g) if the Corporation is a party to any transaction in which the Corporation is not the continuing corporation, the Corporation shall use commercially reasonable efforts to obtain all consents which may be necessary or appropriate under Canadian law to enable the continuing corporation to give effect to the Warrants;

(h) it will use its commercially reasonable efforts to obtain and maintain reporting issuer status or equivalent not in default, and not be in default in any material respect of the applicable requirements of, the applicable securities laws of each of the provinces of Canada and the federal securities laws of the United States;

(i) if at any time after the date of issue of the Warrants no Registration Statement is effective, the Corporation will give notice to the Transfer Agent forthwith and will give notice, in accordance with the provisions set out in Section 12.01, as soon as reasonably practicable, but in any event within 5 Business Days, after learning that no Registration Statement is effective. Such notice must be sent by fax, if possible, to any securities depositary that is a registered holder;

(n) the Corporation will promptly advise the Warrant Agent and the Warrantholder of any default under the terms of this Indenture; and

(c) for the form of the instrument appointing a proxy, the manner in which it may be executed and verification of the authority of a person who executes it on behalf of a Warrantholder; and

32 Warrants outstanding as of the date of such meeting are not present in person or by proxy within 30 minutes from the time fixed for holding the meeting, then the meeting, if called by Warrantholders or on a Warrantholders’ Request, shall be dissolved, but in any other case it shall stand adjourned to such day, being not less than 5 Business Days or more than 10 Business Days later, and to such place and time as may be determined by the chairman. Not less than three Business Days’ notice to Warrantholders shall be given of the time and place of such adjourned meeting in the manner provided in article twelve hereof. Such notice shall state that at the adjourned meeting the Warrantholders present in person or by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars. At the adjourned meeting the Warrantholders present in person or by proxy shall form a quorum notwithstanding the provisions of this subsection 9.12(a) to the contrary and may transact the business for which the meeting was originally called and a motion proposed at such adjourned meeting and passed by the affirmative vote of Warrantholders holding not less than 66 2/3% of the aggregate number of Warrants represented at the adjourned meeting and voted on the motion shall be an Extraordinary Resolution within the meaning of this Indenture, notwithstanding that Warrantholders holding 50% of the aggregate number of Warrants then outstanding Warrant Certificates are not present in person or by proxy at such adjourned meeting.

(e) giving effect to any resolution or Extraordinary Resolution passed as provided in article nine hereof;

(f) making such provisions not inconsistent with this Indenture as may be necessary or desirable with respect to matters or questions arising hereunder, provided that such

35 and skill that a reasonably prudent warrant agent would exercise in comparable circumstances. No provision of this Indenture shall be construed to relieve the Warrant Agent from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct or bad faith.

(b) Conditions for Action: Subject to subsection 11.02(a) hereof, the Warrant Agent shall not be bound to do any thing or take any act or action for the enforcement of any of the obligations of the Corporation under this Indenture unless and until the Warrant Agent shall have received a Warrantholders’ Request setting out the action which the Warrant Agent is required to take and the obligation of the Warrant Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional upon the Warrantholders furnishing, when required by notice by the Warrant Agent, sufficient funds to commence or continue such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent to protect and hold harmless the Warrant Agent against the costs, charges, expenses and liabilities to be incurred thereby and any loss or damage it may suffer by reason thereof.

(c) Deposit of Warrant Certificates: The Warrant Agent may, before commencing or at any time during the continuance of any act, action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder, require the Warrantholders at whose instance it is acting to deposit with the Warrant Agent the Warrant Certificates held by them, for which Warrant Certificates the Warrant Agent shall issue receipts.

(d) Supremacy of Applicable Legislation: Every 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 and of this article eleven.

(a) Entitlement to Rely on Evidence: Whenever it is provided in this Indenture 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 of the facts and opinions stated in all 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. The Warrant Agent may rely and shall be protected in acting upon any such documents deposited with it in purported compliance with any such provision or for any other purpose hereof, but may, in its discretion, require further evidence before acting or relying thereon. The Warrant Agent may also rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, letter, telegram, cablegram or other paper or document believed by it to be genuine and to have been signed, sent or presented by or on behalf of the proper party or parties.

(b) Additional Evidence: In 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

36 be prescribed by Applicable Legislation or as the Warrant Agent may reasonably require by written notice to the Corporation.

(c) Statutory Declarations: Whenever Applicable Legislation requires that evidence referred to in subsection 11.03(a) hereof be in the form of a statutory declaration, the Warrant Agent may accept such statutory declaration in lieu of a Certificate of the Corporation required by any provision hereof. Any such statutory declaration may be made by one or more of the President, any Vice-President, the Chief Financial Officer, the Secretary, the Treasurer, any Assistant Secretary or any Assistant Treasurer of the Corporation.

(d) Proof of Execution: Proof of execution of an instrument in writing 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 him 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.

(a) Protection: By way of supplement to the provisions of any law for the time being relating to warrant agents, it is expressly declared and agreed as follows:

(b) Indemnity: In addition to and without limiting any protection of the Warrant Agent hereunder or otherwise by law, the Corporation agrees to indemnify the Warrant Agent and save it harmless from all liabilities, suits, damages, costs, expenses and actions which may be brought against or suffered by it arising out of or connected with performance by it of its duties hereunder except to the extent that such liabilities, suits, damages, costs and actions are attributable to the negligence or wilful misconduct of the Warrant Agent. Notwithstanding any other provision hereof, this indemnity shall survive any removal or resignation of the Warrant Agent, discharge of this Indenture and termination of any duties and obligations hereunder.

(a) Resignation: The Warrant Agent may resign its duties and obligations and be discharged from all further duties and liabilities hereunder, subject to this subsection 11.07(a), by giving to the Corporation not less than 60 days’ prior notice in writing or such shorter prior notice as the Corporation may accept as sufficient. The Warrantholders, by Extraordinary Resolution, shall have power at any time to remove the Warrant Agent and to appoint a new warrant agent. In the event of the Warrant Agent resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new warrant agent unless such Extraordinary Resolution has appointed a new warrant agent; failing such appointment by the Corporation, the retiring Warrant Agent, at the expense of the Corporation, or any Warrantholder may apply to a judge of the Ontario Court of Justice (General Division), on such notice as such judge may direct for the appointment of a new warrant agent; provided that any new Warrant Agent so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Warrantholders. Any new warrant agent appointed under this subsection 11.07(a) shall be a corporation authorized to carry on the business of a trust company or transfer agent in the Province of Ontario and, if required by Applicable Legislation of any other province in Canada, in such other provinces. On any such appointment the new warrant agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant Agent without any further assurance, conveyance, act or deed, but there shall be immediately executed, at the expense of the Corporation, all such conveyances or other instruments as may, in the opinion of Counsel, be necessary or advisable for the purpose of assuring the same to the new warrant agent, provided that, following any resignation or removal of the Warrant Agent and appointment of a successor warrant agent, the successor warrant agent shall have executed an appropriate instrument accepting such appointment and, at the request of the Corporation, the predecessor Warrant Agent shall execute and deliver to the successor warrant agent an appropriate instrument transferring to such successor warrant agent all rights and powers of the Warrant Agent hereunder so ceasing to act.

38 (b) Notice of Successor: Upon the appointment of a successor warrant agent, the Corporation shall promptly notify the Warrantholders thereof in the manner provided for in article twelve hereof.

(c) No Further Act for Merger: Any corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom, or any corporation succeeding to the trust or transfer agency business of the Warrant Agent shall be the successor to the Warrant Agent hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for appointment as a successor warrant agent under subsection 11.07(a) hereof.

(d) Certification: Any Warrant Certificate countersigned but not delivered by a predecessor Warrant Agent may be delivered by the successor warrant agent in the name of the predecessor or successor warrant agent.

(a) Representation: The Warrant Agent represents to the Corporation that at the time of the execution and delivery hereof no material conflict of interest exists in the Warrant Agent’s role as a fiduciary hereunder and agrees that in the event of a material conflict of interest arising hereafter it will, within 90 days after ascertaining that it has such material conflict of interest, either eliminate the same or assign its duties and obligations hereunder to a successor warrant agent approved by the Corporation and meeting the requirements set forth in subsection 11.07(a) hereof.

(a) Notice: Unless herein otherwise expressly provided, a notice to be given hereunder to Warrantholders will be deemed to be validly given if the notice is sent by ordinary surface or air mail, postage prepaid, addressed to the Warrantholders or delivered (or so mailed to certain Warrantholders and so delivered to the other Warrantholders) at their respective addresses appearing on the registers of holders described in section 2.08 hereof, provided, however, that if, by reason of a strike, lockout or other work stoppage, actual or threatened, involving Canadian postal employees, the notice could reasonably be considered unlikely to reach or likely to be delayed in reaching its destination, the notice will be valid and effective only if it is so delivered or is given by publication twice in the Report on Business section in the national edition of The Globe and Mail newspaper.

(b) Date of Notice: A notice so given by mail or so delivered will be deemed to have been given on the first Business Day after it has been mailed or on the day on which it has been delivered, as the case may be, and a notice so given by publication will be deemed to have been given on the second day on which it has been published as required. In determining under any provision hereof the date when notice of a meeting or other event must be given, the date of giving notice will be included and the date of the meeting or other event will be excluded. Accidental failure or omission in giving notice or accidental failure to mail notice to any Warrantholder will not invalidate any action or proceeding founded thereon.

(a) Notices: Unless herein otherwise expressly provided, any notice to be given hereunder to the Corporation or to the Warrant Agent shall be deemed to be validly given if delivered by prepaid courier, if transmitted by telecopier or other means of prepaid, transmitted, recorded communication or if sent by registered mail, postage prepaid:

(c) Postal Disruption: If, by reason of a strike, lockout or other work stoppage, actual or threatened, involving postal employees, any notice to be given to the Warrant Agent or to the Corporation hereunder could reasonably be considered unlikely to reach its destination, such notice shall be valid and effective only if it is delivered by prepaid courier or transmitted by telecopier or other means of prepaid, transmitted, recorded communication, such notice to be deemed to have been received on the date of delivery or transmission.

If the Common Shares are also then listed on the Toronto Stock Exchange. certificates representing the Common Shares will also bear the following legend

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, THE SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON TSX.”

Section 4.02 Effect of Exercise of Warrants:

Section 4.03 Subscription for Less than Entitlement:

The holder of any Warrant Certificate may exercise a number of Warrants less than the maximum number represented by the surrendered Warrant Certificate subject to Section 2.02(d). In such event, the holder thereof upon exercise thereof shall be entitled to receive a new Warrant Certificate complying with section 2.02 hereof in respect of the balance of the Warrants not exercised.

Section 4.04 Warrant Certificates for Fractions of Common Shares:

To the extent that the holder of a Warrant Certificate is entitled to receive on the exercise or partial exercise thereof a fraction of a Common Share, such right may only be exercised in respect of such fraction in combination with another Warrant Certificate which in the aggregate entitles the Warrantholder to receive a whole number of Common Shares.

Section 4.05 Expiration of Warrants:

After the Time of Expiry all rights under any Warrant in respect of which the right of subscription and purchase therein and herein provided shall not theretofore have been exercised shall wholly cease and terminate and such Warrant shall be void, of no force or effect and of no value whatsoever.

Section 4.06 Securities Restrictions; Legends:

Notwithstanding any provision to the contrary contained in this Indenture, no Common Shares will be issued pursuant to the exercise of any Warrant if the issuance of such securities would constitute a violation of the securities laws of any applicable jurisdiction, and, without limiting the generality of the foregoing, the Corporation will legend the certificates representing the Common Shares if, in the opinion of counsel to the Corporation such legend is necessary in order to avoid a violation of any securities laws of any applicable jurisdiction or to comply with the requirements of any stock exchange on which the Common Shares are listed, provided that if, at any time, in the opinion of outside counsel to the Corporation, acting reasonably, such legends are no longer necessary in order to avoid a violation of any such laws, or the holder of any such legended certificate, at his expense, provides the Corporation with evidence satisfactory in form and substance to the Corporation (which may include an opinion of counsel of recognized standing satisfactory to the Corporation) to the effect that such holder is entitled to sell or otherwise transfer such securities in a transaction in which such legends are not required, such legended certificates may thereafter be surrendered to the Corporation in exchange for a certificate which does not bear such legends. For greater certainty, should no Registration Statement be effective, the Corporation shall issue legended Common Shares in accordance with 4.01(d).

ADJUSTMENTS

Section 5.01 Adjustment of Exercise Price and Number of Common Shares Purchasable Upon Exercise:

The Exercise Price and the number of Common Shares purchasable upon the exercise of the Warrants shall be subject to adjustment from time to time in the events and in the manner provided in the following subsections:

(any of such events in paragraphs 5.01(a)(i), (ii), (iii) and (iv) above being herein called a “Common Share Reorganization”), the Exercise Price shall be adjusted on the earlier of the record date on which holders of Common Shares are determined for the purposes of the Common Share Reorganization and the effective date of the Common Share Reorganization to the amount determined by multiplying the Exercise Price in effect immediately prior to such record date or effective date, as the case may be, by a fraction:

To the extent that any adjustment in the Exercise Price occurs pursuant to this subsection 5.01(a) as a result of the fixing by the Corporation of a record date for the distribution of securities exchangeable for or convertible into Common Shares, the Exercise Price shall be readjusted immediately after the expiry of any relevant exchange

or conversion 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 expiry and shall be further readjusted in such manner upon the expiry of any further such right. Any Warrantholder who has not exercised his right to subscribe for and purchase Common Shares on or prior to the record date of such stock dividend or distribution or the effective date of such subdivision or consolidation, as the case may be, upon the exercise of such right thereafter shall be entitled to receive and shall accept in lieu of the number of Common Shares then subscribed for and purchased by such Warrantholder, at the Exercise Price determined in accordance with this subsection 5.01(a) the aggregate number of Common Shares that such Warrantholder would have been entitled to receive as a result of such Common Share Reorganization, if, on such record date or effective date, as the case may be, such Warrantholder had been the holder of record of the number of Common Shares so subscribed for and purchased.

I. either (a) the product of the number of Common Shares offered during the Rights Period pursuant to the Rights Offering and the price at which such Common Shares are offered, or, (b) the product of the exchange or conversion price of the securities so offered and the number of Common Shares for or into which the securities offered pursuant to the Rights Offering may be exchanged or converted, as the case may be, by

II. the Current Market Price of the Common Shares as of the record date for the Rights Offering; and

I. the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such record date, and

II. the fair market value, as determined in good faith by the directors of the Corporation (whose determination shall be conclusive, subject to the prior written consent, if required, of any stock exchange on which the Common Shares are then listed), of such dividend, cash, securities, rights, options, warrants, evidences of indebtedness or property or assets to be issued or distributed in the Special Distribution, and

Any Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of such calculation. To the extent that any adjustment in the Exercise Price occurs pursuant to this subsection 5.01(c) as a result of the fixing by the Corporation of a record date for the issue or distribution of rights, options or warrants to acquire Common Shares or securities exchangeable for or

convertible into Common Shares referred to in this subsection 5.01(c), the Exercise Price shall be readjusted immediately after the expiry of any relevant exercise, exchange or conversion right to the amount which would then be in effect based upon the number of Common Shares issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

(any of such events being called a “Capital Reorganization”), after the effective date of the Capital Reorganization the Warrantholder shall be entitled to receive, and shall accept, for the same aggregate consideration, upon exercise of the Warrants, in lieu of the number of Common Shares to which the Warrantholder was theretofor entitled upon the exercise of the Warrants, the kind and aggregate number of shares and other securities or property resulting from the Capital Reorganization which the Warrantholder would have been entitled to receive as a result of the Capital Reorganization if, on the effective date thereof, the Warrantholder had been the registered holder of the number of Common Shares which the Warrantholder was theretofor entitled to purchase or receive upon the exercise of the Warrants. If necessary, as a result of any such Capital Reorganization, appropriate adjustments shall be made in the application of the provisions of this Warrant Indenture with respect to the rights and interests thereafter of the Warrantholder to the end that the provisions 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 the Warrants. Any such adjustments shall be made by and set forth in an indenture supplemental hereto with its successor or such corporation or other entity, as applicable, contemporaneously with such Capital Reorganization, provided that no such adjustments shall be prejudicial to the interests of any Warrantholders, and which supplemental indenture shall be approved by action by the directors and shall for all purposes be conclusively deemed to be an appropriate adjustment. To give effect to the provisions of this subsection, the Corporation shall or shall impose upon its successor or such purchasing corporation or entity, as the case may be, prior to or contemporaneously with the Capital Reorganization, an agreement or an undertaking which shall provide, to the extent possible, for the applications of the provisions set forth herein with respect to the rights and interests thereafter of the Warrantholder to the extent that the adjustment provisions set forth in this Warrant Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to which the Warrantholder is entitled on exercise of acquisition rights hereunder. Any such agreement or undertaking shall provide that such adjustments shall apply to successive Capital Reorganizations.

Section 5.02 Rules Regarding Calculation of Adjustment of Exercise Price and Number of Common Shares Purchasable Upon Exercise:

For the purposes of section 5.01 hereof the following subsections shall apply:

Section 5.03 Postponement of Subscription:

In any case in which this article five shall require that an adjustment shall be effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event:

provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing the right of such holder upon the occurrence of the event requiring the adjustment, to an adjustment in the Exercise Price or the number of Common Shares purchasable on the exercise of any Warrant and to such distributions declared with respect to any additional Common Shares issuable on the exercise of any Warrant.

Section 5.04 Notice of Adjustment of Exercise Price and Number of Common Shares Purchasable Upon Exercise:

Where a notice pursuant to this subsection 5.04(b) has been given, the Warrant Agent shall be entitled to act and rely on any adjustment calculation of the Corporation or of the auditors of the Corporation.

PURCHASES BY THE CORPORATION

Section 6.01 Optional Purchases by the Corporation:

Subject to applicable law, the Corporation may from time to time purchase Warrants on any stock exchange, in the open market, by private agreement or otherwise.

THIS IS TO CERTIFY THAT, for value received, <> (the “holder”) is entitled to subscribe for and to purchase, AT ANY TIME PRIOR TO 5:00 P.M., DENVER TIME, ON THE EXPIRY DATE (as hereinafter defined), fully paid and non-assessable common shares (“Common Shares”) of U.S. Gold Corporation (the “Corporation”) as constituted on the date hereof (as hereinafter defined), on the basis of one Common Share for each one Warrant (subject to adjustment in certain circumstances), at an exercise price of US$10.00 per Common Share (subject to adjustment in certain circumstances), by surrendering this Warrant Certificate to the warrant agent specified below with a subscription form (FORM 1) properly completed and executed, and a certified cheque, bank draft or money order in lawful money of the United States payable to or to the order of the Warrant Agent (as hereinafter defined), for the total purchase price of the Common Shares so subscribed for and purchased.

The Expiry Date is February 22, 2011.

The holder of this Warrant Certificate may subscribe for and purchase less than the number of Common Shares entitled to be subscribed for and purchased on surrender of this Warrant Certificate. If the subscription does not exhaust the Warrants represented by this Warrant Certificate, a Warrant Certificate representing the balance of the Warrants will be issued to the holder. No Warrant Certificate representing fractional Warrants will be issued and the holder hereof understands and agrees that such holder will not be entitled to any cash payment or other form of compensation in respect of a fractional Warrant. By acceptance hereof, the holder expressly waives any right to receive fractional Common Shares upon exercise hereof. If the number of Common Shares to which a Warrantholder would otherwise be entitled upon the exercise of this Warrant Certificate is not a whole number, then the number of Common Shares to be issued will be rounded down to the next whole number.

The principal office of Equity Transfer Services Inc. (the “Warrant Agent”) in the City of Toronto, Ontario, has been appointed the warrant agent to receive subscriptions for Common Shares and payments from holders of Warrant Certificates. This Warrant Certificate, the subscription form (FORM 1), and a certified cheque, bank draft or money order shall be deemed to be surrendered to the Warrant Agent only upon personal delivery thereof or, if sent by post or other means of transmission, upon receipt thereof by the Warrant Agent at the office specified above. The Corporation may also provide for other places at which this Warrant Certificate may be surrendered for exchange or exercise. If mail is used for delivery of a Warrant Certificate, for the protection of the holder, registered mail should be used and sufficient time should be allowed to avoid the risk of late delivery.

Certificates representing Common Shares subscribed for and purchased will be mailed to the persons specified in the subscription form (FORM 1) at the respective addresses specified therein or, if so specified in the subscription form (FORM 1), delivered to such persons at the office of the Warrant Agent where the applicable Warrant Certificate was surrendered, when the transfer books of the Corporation have been opened for three Business Days after the due surrender of such Warrant Certificate and payment as aforesaid, including any applicable taxes.

This Warrant Certificate may, upon compliance with the reasonable requirements and charges of the Warrant Agent, be divided by completing and executing FORM 2 and delivering the Warrant Certificate to the Warrant Agent.

The Warrants represented 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 office 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 executed in a manner 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 recorded 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.

If any Common Shares issuable upon the exercise of Warrants require the maintenance of a current Registration Statement, with respect to such Common Shares under the Securities Act of 1933, as amended (the “1933 Act”), in no event shall such Common Shares be issued unless the Common Shares are registered under the 1933 Act pursuant to an effective Registration Statement and the Company causes to be delivered to the holder a U.S. Prospectus; provided, however that, if the Registration Statement ceases to be effective, prior to the Expiry Time and for so long as the Registration Statement is not effective, subject to applicable law, a holder of any Warrant may, at its option: (i) exercise such Warrants, if the holder is not a U.S. Purchaser and the holder delivers a duly completed and executed Warrant Exercise Certification (in the form attached as Schedule B to the Indenture) certifying that the holder: (A)(1) is not in the United States; (2) is not a U.S. Person and is not exercising the Warrants for, or on behalf or benefit of, a U.S. Person or person in the United States; (3) did not execute or deliver the Warrant Subscription Form in the United States; (4) agrees not to engage in hedging transactions with regard to the Securities prior to the expiration of the one-year distribution compliance period set forth in Rule 903(b)(3) of Regulation S; (5) acknowledges that the Common Shares issuable upon exercise of the Warrants are “restricted securities” as defined in Rule 144 of the 1933 Act and upon the issuance thereof, and until such time as the same is no longer required under the applicable requirements of the 1933 Act or applicable U.S. state laws and regulations, the certificates representing the Common Shares will bear a restrictive legend; and (6) acknowledges that the Corporation shall refuse to register any transfer of the Common Shares not made in accordance with the provisions of Regulation S, pursuant to registration under the 1933 Act, or pursuant to an available exemption from registration under the 1933 Act; and (B) neither the Corporation nor the holder has engaged in any “directed selling efforts” (as defined in Regulation S) in the United States; or (ii) exercise such Warrants in a transaction that does not require registration under the 1933 Act or any applicable U.S. state laws and regulations and the holder has (A) delivered a duly completed and executed Warrant Exercise Certification (in the form attached hereto as Schedule B) certifying that the holder is exercising the Warrants pursuant to such exemptions and (B) furnished to the Corporation, prior to such exercise, an opinion of counsel of recognized standing in form and substance satisfactory to the Corporation to such effect. If no Registration Statement is effective at any time when any Warrant is exercised, the holder shall deliver a completed Warrant Exercise Certification (attached as Schedule B to the Indenture) to the Transfer Agent and the Corporation.

This Warrant Certificate represents warrants of the Corporation issued or issuable under the provisions of an indenture (which indenture together with all other instruments supplemental or ancillary thereto is herein referred to as the “Warrant Indenture”) dated as of February 22, 2006, between the Corporation and the Warrant Agent, to which reference is hereby made for particulars of the rights of the holders of the Warrant Certificates, the Corporation and the Warrant Agent in respect thereof and the terms and conditions upon which the Warrants represented hereby 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 of this Warrant Certificate by acceptance hereof assents, it being expressly understood that the provisions of the Warrant Indenture and this Warrant Certificate are for the sole benefit of the Corporation, the

Words and terms in this Warrant Certificate with the initial letter or letters capitalized and not defined herein shall have the meanings ascribed to such capitalized words and terms in the Warrant Indenture.

Nothing contained in this Warrant Certificate, the Warrant Indenture or otherwise shall be construed as conferring upon the holder hereof any right or interest whatsoever as a holder of Common Shares or other shareholder of the Corporation or any other right or interest except as herein and in the Warrant Indenture expressly provided.

The Warrant Indenture provides for adjustments to the exercise price of the Warrants and to the number and kind of securities purchasable upon exercise upon the happening of certain stated events including the subdivision or consolidation of the Common Shares, certain distributions of Common Shares or securities exchangeable for or convertible into Common Shares or of other assets or property of the Corporation, certain offerings of rights, warrants or options and certain reorganizations.

The Warrant Indenture provides for the giving of notice by the Corporation prior to taking certain actions specified therein. The Corporation may from time to time purchase any of the Warrants by private contract or otherwise. Any such Warrants purchased by the Corporation shall be cancelled.

This Warrant Certificate, the Warrants represented by this Warrant Certificate and the Warrant Indenture shall be governed by and performed, construed and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.
