In addition to the foregoing, all Royalty Deposits payable to Unitholders under this Indenture shall be made free and clear of and without deduction or withholding for or on account of any non-U.S. tax, except to the extent that the Trustee or the Corporation, as the case may be, is required by law to make payment subject to any such non-U.S. tax.

ARTICLE IV

CONVERSION OF UNITS

Section 4.01

Conversion Option and Conversion Price

(1)

Subject to and upon compliance with the provisions of this Article IV and applicable laws, and subject to compliance with any applicable restrictions set forth in the legends set forth on the Units, the holder of any Unit shall have the right, at such holder’s option, at any time and from time to time prior to 4:00 p.m. (Vancouver time) on the Business Day immediately preceding the Expiry Date, to convert the Conversion Amount with respect to that Unit into fully paid and non-assessable Common Shares at the Conversion Price then in effect.

(2)

Notwithstanding (1), subject to and upon compliance with the provisions of this Article IV and applicable laws, the Corporation shall have the right, at its option, prior to 4:00 p.m. (Vancouver time) on the earlier of: (a) the fifth Business Day following any Forced Conversion Event and (b) the Expiry Date, to convert the Conversion Amount with respect to that Unit into fully paid and non-assessable Common Shares at the Conversion Price then in effect. The procedures set forth in Sections 4.02 through 4.11 shall apply to the Conversion Option of the Corporation exercised pursuant this Section 4.01(2)(c), mutatis mutandis, except that Units need not be surrendered to the Trustee.

Section 4.02

Conversion Procedure

(1)

In order to exercise the Conversion Option, the holder of any Unit to be converted shall, within the time specified in Section 4.01(1)(c), surrender such Units to the Trustee at its principal office in Golden, Colorado accompanied by a written notice (which shall be irrevocable) substantially in the form of Schedule “C” attached hereto, duly signed by such 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 Trustee, stating:

- 20 -

(a)

that such holder elects to convert such Units; and

(b)

the names (with addresses) in which the certificates representing the Common Shares issuable upon such conversion are to be registered and, if there is more than one name, the number of shares to be registered in each of such names.

If any of the Common Shares into which such Units are to be converted are to be issued to a Person or Persons other than the holder of such Units, such notice shall be accompanied by payment to the Trustee of any transfer tax which may be payable by reason thereof and an executed form of transfer. Upon the surrender of the Units accompanied by such written notice:

(c)

the holder of such Units shall have subscribed for the number of Common Shares which such holder shall be entitled to receive on such conversion;

(d)

subject to Section 4.02(2) and (3), the holder of such Units shall have and be deemed to have released the Corporation from all liability with respect to such Units to be converted effective upon such conversion;

(e)

such surrender shall constitute full payment of the Conversion Price for the Common Shares issuable upon such conversion; and

(f)

all Common Shares issued upon exercise of the Conversion Option shall be duly and validly issued as fully paid and non-assessable.

The date of receipt by the Trustee of the Units to be converted and such notice is herein referred to as the “Conversion Date” of such Unit.

(2)

The Trustee shall promptly notify the Corporation and the Transfer Agent of the receipt of a Conversion Notice and within five Business Days of such notification and surrender of any Units to be converted, the Corporation shall, by instruction to the Transfer Agent, issue or cause to be issued to the holder of such Units, or on the written order of such holder, a certificate or certificates in the name or names of the Person or Persons specified in the written notice referred to in Section 4.02(1) for the number of Common Shares deliverable upon the conversion of such Units and provision shall be made in respect of any fraction of a share as provided in Section 4.03. Upon receipt of the instruction of the Corporation relating to the issuance of Common Shares upon the conversion of Units, the Transfer Agent shall deliver the share certificates set out in such instruction to the Trustee to be delivered to the holder whose Units were surrendered for conversion or the Person designated in the Conversion Notice. Such conversion shall be deemed to have been effected immediately at 4:00 p.m. (Vancouver time) on the Conversion Date and, at that time, the rights of the holder of such Units as a Unitholder shall cease and the Person or Persons in whose name or names any certificate or certificates for Common Shares shall be deliverable upon such conversion shall be deemed to have become on such date the holder or holders of record of the Common Shares represented thereby; provided, however, that the surrender of a certificate for Units for conversion on any date on which the transfer registers for Common Shares or for the Units shall be closed shall not be effective to constitute the Person or Persons entitled to receive the Common Shares upon such conversion as the holder or holders of record of such Common Shares on such date, but such surrender shall be

- 21 -

effective to constitute the Person or Persons entitled to receive such Common Shares as the holder or holders of record thereof for all purposes at 4:00 p.m. (Vancouver time) on the next succeeding Business Day on which such transfer registers are open. No payment or adjustment shall be made upon any conversion on account of any dividends on the Common Shares issuable upon conversion.

(3)

Upon surrender to the Trustee of any certificate representing the Units which are to be converted in part only, the holder thereof shall be entitled to receive, without expense to such holder, one or more new certificates representing the unconverted Units evidenced by such certificate.

Section 4.03

No Fractional Shares

Notwithstanding anything herein contained, the Corporation shall in no case be required to issue fractional Common Shares upon the conversion of any Unit. If any fractional interest in a Common Share would, except for the provisions of this Section 4.03, be deliverable upon the conversion of any Unit, the Corporation shall adjust such fractional interest by payment to the holder of such surrendered Unit of an amount equal (to the nearest cent) to the product of such fractional interest and the Conversion Price in effect on the Conversion Date of such Unit.

Section 4.04

Effect of Conversion

Provided that all Common Shares issuable upon exercise of the conversion right are issued, all Remaining Obligations with respect to the Units so converted will be deemed to have been satisfied in full as at the applicable Conversion Date. Notwithstanding any provisions of this Indenture to the contrary, provided that the Common Shares issuable upon exercise of the Conversion Option are issued, from and after the Conversion Date, any Remaining Obligations of the Corporation under the Units so converted will cease.

Section 4.05

Adjustment of Conversion Option

(1)

From and after the date hereof, the Conversion Price will be subject to adjustment in the following events and in the following manner:

(a)

if and whenever the Corporation shall:

(i)

subdivide, redivide or change its outstanding Common Shares into a greater number of shares;

(ii)

reduce, combine or consolidate its outstanding Common Shares into a smaller number of shares; or

(iii)

issue to all or substantially all of the holders of the Common Shares, by way of stock distribution, stock dividend or otherwise, Common Shares or securities convertible into Common Shares,

(any of the events described in (i), (ii) and (iii) being referred to as a “Share Reorganization”), the Conversion Price shall be adjusted,

- 22 -

effective immediately after the record date at which the holders of Common Shares are determined for the purposes of the Share Reorganization or, if no record date is fixed, the effective date of the Share Reorganization, by multiplying the Conversion Price in effect on such record or effective date, as the case may be, by a fraction of which:

(A)

the numerator shall be the number of Common Shares outstanding on such record or effective date before giving effect to the Share Reorganization; and

(B)

the denominator shall be the number of Common Shares outstanding after giving effect to such Share Reorganization, including, in the case of a distribution of Convertible Securities, the number of Common Shares that would have been outstanding if such securities had been converted into or exchanged for Common Shares on such record or effective date;

(b)

if and whenever there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in Section 4.05(1õõõõÿ or a consolidation, amalgamation or merger of the Corporation with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the Collateral as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity (any such event being called a “Capital Reorganization”), any holder who has not exercised its Conversion Option prior to the effective date of such Capital Reorganization, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of Common Shares such holder would otherwise be entitled to acquire, the number of shares and warrants or other securities or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such Capital Reorganization, or to which such sale or conveyance may be made, as the case may be, that such holder would have been entitled to receive on such Capital Reorganization, if, on the record date or the effective date thereof, as the case may be, the holder had been the registered holder of the number of Common Shares sought to be acquired by it. If necessary, appropriate adjustments shall be made in the application of the provisions set forth in this Section 4.05 with respect to the rights and interests thereafter of the Unitholder to the end that the provisions set forth in this Section 4.05 shall thereafter correspondingly be made applicable as nearly as may be reasonable in relation to any shares or other securities or property thereafter deliverable upon the conversion of the Units;

(c)

if and whenever the Corporation shall issue rights, options or warrants to all or substantially all the holders of the Common Shares pursuant to

- 23 -

which those holders are entitled to subscribe for, purchase or otherwise acquire Common Shares, Participating Shares or Convertible Securities within a period of 45 days from the date of issue thereof at a price, or at a conversion price, of less than 95% of the Current Market Price at the record date for such distribution (any such issuance being herein called a “Rights Offering” and Common Shares, Convertible Securities or Participating Shares that may be acquired in exercise of the Rights Offering or upon conversion of the Convertible Securities offered by the Rights Offering being herein called the “Offered Shares”), the Conversion Price shall be adjusted, effective immediately after the record date at which holders of Common Shares are determined for the purposes of the Rights Offering, by multiplying the Conversion Price in effect on such record date by a fraction of which:

(i)

the numerator shall be the sum of:

(A)

the number of Common Shares outstanding on such record date; and

(B)

a number obtained by dividing:

either,

01.

the product of the total number of Offered Shares offered pursuant to the Rights Offering and the price at which such shares are so offered, or

02.

the product of the maximum number of Common Shares into or for which the Offered Shares may be converted or exchanged and the conversion or exchange price of such shares,

as the case may be, by

II.

the Current Market Price of the Common Shares on such record date; and

(ii)

the denominator shall be the sum of:

(A)

the number of Common Shares outstanding on such record date; and

(B)

the number of Offered Shares so offered for subscription or purchase (or, in the case of Convertible Securities, the maximum number of Common Shares for or into which the

- 24 -

securities so offered for subscription or purchase may be converted or exchanged).

Any Offered Shares owned by or held for the account of the Corporation or its Affiliates shall be deemed not to be outstanding for the purpose of any computation; if all the rights, options or warrants are not so issued or if all rights, options or warrants are not exercised prior to the expiration thereof, the Conversion Price shall be readjusted to the Conversion Price in effect immediately prior to the record date and the Conversion Price shall be further adjusted based upon the number of Offered Shares (or Convertible Securities into Offered Shares) actually delivered upon the exercise of the rights, options or warrants, as the case may be, but subject to any other adjustment required hereunder by reason of any event arising after that record date; and

(d)

if and whenever the Corporation shall issue or distribute to all or substantially all the holders of the Common Shares (i) shares of any class other than Common Shares, or (ii) rights, options or warrants other than rights, options or warrants exercisable within 45 days from the date of issue thereof at a price, or at a conversion price, of less than 95% of the Current Market Price at the record date for such distribution, or (iii) evidences of indebtedness, or (iv) any other assets (excluding Cash Dividends Paid in the Ordinary Course) and that issuance or distribution does not constitute a Share Reorganization or a Rights Offering (any of those events being herein called a “Special Distribution”), the Conversion Price shall be adjusted, effective immediately after the record date at which the holders of Common Shares are determined for purposes of the Special Distribution, by multiplying the Conversion Price in effect on such record date by a fraction of which:

(i)

the numerator shall be the difference between:

(A)

the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such date; and

(B)

the fair market value, as determined by the Directors (whose determination shall be conclusive), to the holders of Common Shares of the shares, rights, options, warrants, evidences of indebtedness or property or other assets issued or distributed in the Special Distribution, and

(ii)

the denominator shall be the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such date.

- 25 -

Any Common Shares owned by or held for the account of the Corporation or its Affiliates shall be deemed not to be outstanding for the purpose of any such computation. To the extent that the distribution of shares, rights, options, warrants, evidences of indebtedness or assets if not so made or to the extent that any rights, options or warrants so distributed are not exercised, the Conversion Price shall be readjusted to the Conversion Price that would then be in effect based upon the shares, rights, options, warrants, evidences of indebtedness or assets actually distributed or based upon the number of Common Shares or Convertible Securities actually delivered upon the exercise of the rights, options or warrants, as the case may be, but subject to any other adjustment required hereunder by reason of any event arising after the record date.

Section 4.06

Adjustment Rules

(1)

The adjustments provided for in Section 4.05 in the number of Common Shares and classes of securities which are to be received on the conversion of Units are cumulative and shall apply to successive issues, subdivisions, combinations, consolidations, distributions and any other events that would require an adjustment of the Conversion Price or the number or kind securities issuable hereunder.

(2)

No adjustment in the Conversion Price shall be required unless such adjustment would result in a change of at least 1% in the Conversion Price then in effect; provided, however, that any adjustments which, but for the provisions of this Section 4.06(2)(c), would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.

(3)

If and whenever at any time from the Closing Date, the Corporation shall reclassify or otherwise change the outstanding Common Shares, the Conversion Option shall be adjusted effective immediately upon the reclassification becoming effective so that Unitholders who exercise their Conversion Option thereafter shall be entitled to receive Common Shares as they would have received had the Units been converted immediately prior to the effective date, subject to adjustment thereafter in accordance with provisions the same, as nearly as may be possible, as those contained in Section 4.05.

(4)

Notwithstanding the foregoing, no adjustment will be made in respect of an event described in Section 4.05(1)(c) or (d) if the Unitholders are entitled to participate in the event on the same terms, mutatis mutandis, as if they had exercised their Conversion Option immediately before the effective date of or record date for the event, such participation being subject to the prior written consent of any stock exchange upon which the Common Shares are listed for trading.

(5)

No adjustment in the Conversion Price shall be made pursuant to Section 4.05 in respect of the issue from time to time of Common Shares or Convertible Securities to holders of Common Shares who exercise an option to receive substantially equivalent dividends in Common Shares or Convertible Securities in lieu of receiving Cash Dividends Paid in the Ordinary Course in the form of cash payments.

- 26 -

(6)

In the event of any question arising with respect to the adjustments provided in Section 4.05, such question shall conclusively be determined by a firm of chartered accountants or certified public accountants appointed by the Corporation and acceptable to the holder (who may be the Corporation’s Auditors). Such independent accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation and the holder.

(7)

As a condition precedent to the taking of any action which would require an adjustment in the Conversion Option, including the number of Common Shares which are to be received upon the exercise thereof, the Corporation shall take any corporate action which may, in the opinion of its Counsel, be necessary in order that the Corporation or a Successor Corporation has unissued and reserved in its authorized capital and may validly and legally issue as fully paid and non-assessable all the shares which the holders of such Units issued by it are entitled to receive on the full exercise of the Conversion Option in accordance with the provisions hereof.

(8)

At least 21 Business Days before the earlier of the record date (if one is fixed) or the effective date for any event referred to in Section 4.05, that requires or might require an adjustment in the Conversion Option, including the Conversion Price and the number of Common Shares issuable on the exercise of the Conversion Option, the Corporation will give notice to the Trustee and the Unitholders of the particulars of the event and, to the extent determinable, any adjustment required. If it is not reasonably practicable for the Corporation to give 21 Business Days’ notice as aforesaid, the Corporation will give as much notice as is reasonably practicable in the circumstances.

(9)

The Corporation covenants with the holder that it will not close its transfer books or take any other corporate action which might deprive the holder of the opportunity to exercise its Conversion Option during the period of 21 Business Days after the giving of the notice set forth in Section 4.06(8)(c).

(10)

If and whenever the Corporation shall take any action affecting or relating to the Common Shares, other than any action described in this Article, which in the opinion of the Directors would prejudicially affect the rights of any Unitholders, the Conversion Price and, if required, the Directors shall use reasonable commercial efforts, subject to the approval of any stock exchange(s) on which the Common Shares are listed and posted for trading, to adjust the number of Common Shares issuable upon the exercise of the Conversion Option in such manner as the Directors, acting in good faith, reasonably determine to be equitable in the circumstances to such holders.

Section 4.07

Postponement of Issuance

(1)

In any case where the application of Section 4.05 results in an adjustment to the Conversion Price taking effect immediately after the record or effective date for a specific event, if any Conversion Option is exercised after that record or effective date and prior to completion of the event, the Corporation may postpone the issuance to the holder of the Units of the Common Shares to which he is entitled by reason of the adjustment to the Conversion Price but such Common Shares shall be so issued and delivered to that holder upon completion of that event, with the number of such Common Shares calculated on the basis of the Conversion Price

- 27 -

on the Conversion Date adjusted for completion of that event, and the Corporation shall deliver to the Person or Persons in whose name or names the Common Shares are to be issued an appropriate instrument evidencing his or their right to receive such Common Shares.

(2)

Notwithstanding Section 4.07(1), neither the Corporation nor the Trustee shall be required to effect a Conversion for a period of three (3) Business Days immediately preceding any Royalty Record Date.

Section 4.08

Certificate as to Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment in the Conversion Price or Conversion Option lodge with the Trustee a Certificate of the Corporation specifying the nature of the event requiring the adjustment and the amount of the adjustment necessitated thereby and setting forth, in reasonable detail, the method of calculation and the facts upon which such calculation is based, and the Trustee shall be entitled to rely exclusively on such Certificate. The Corporation shall forthwith give to the Unitholders notice, in the manner provided in Article X, of such adjustment, specifying the event requiring such adjustment and the Conversion Price after giving effect to such adjustment. Any Certificate of the Corporation delivered pursuant to this Section 4.08 and the amount of the adjustment specified therein shall, subject to the provisions of Section 4.06(6)(c) and absent manifest error, be conclusive and binding on all parties in interest.

Section 4.09

Cancellation of Units

All Units surrendered for conversion shall be cancelled by the Trustee and no Units shall be issued in substitution therefor, except if all of the Units represented by a certificate surrendered for conversion are not converted, in which case a certificate representing the unconverted Units shall be issued.

Section 4.10

Reservation of Shares

The Corporation shall at all times while any of the Units remain outstanding reserve and keep available out of its authorized and unissued Common Shares, for the purpose of effecting the conversion of the Units, such number of Common Shares as shall from time to time be sufficient to effect the conversion of all Units. As a condition precedent to the taking of any action which would require an adjustment to the Conversion Price, the Corporation shall take any corporate action which may, in the opinion of Counsel, be necessary in order that the Corporation shall have unissued and reserved in its authorized capital, and may validly and legally issue, the shares to which the Unitholders are entitled on the full exercise of their Conversion Option in accordance with the provisions hereof.

Section 4.11

Governmental Requirements

If any Common Shares of the Corporation, reserved or to be reserved for the purpose of conversion of the Units hereunder, require qualification with or approval of any governmental authority under any federal or provincial law applicable in British Columbia before such Common Shares may be validly issued upon conversion, the Corporation shall take such action as may be necessary to secure such qualification or approval, as the case may be.

In addition, the Corporation shall not declare any dividend to the holders of its issued and outstanding Common Shares or securities ranking junior to the Units if at the time the Board of Directors resolves to make the said declaration, the Corporation

Section 5.12

any action that authorizes, creates or issues indebtedness which upon winding up, dissolution, liquidation, insolvency, receivership, bankruptcy

or similar event (collectively, “Liquidation”) has preferences superior to or on a parity with the Units;

(b)

any action that restructures any existing indebtedness having Liquidation preferences senior to or on a parity with the Units;

(c)

any amendment of the Corporation's charter documents or bylaws or entering into any indenture or similar agreement that materially adversely affects the rights of the Units; and

(d)

any action that would have a material adverse effect on or would result in the transfer, assignment or sale of any of the Collateral by the Corporation;

provided, however, that if any proposed action or event would trigger prior approval under clause (1) above, no such prior approval shall be required if the Corporation provides at least twenty (20) days’ advance written notice of such action or event to the Trustee and takes such actions as are necessary and appropriate to provide that upon consummation of any such action or event the Units are paid-in-full as of consummation thereof.

(2)

Notwithstanding the foregoing, no approval shall be required for the Corporation to:

(a)

enter into or amend the terms of a Subject Agreement;

The Corporation shall deliver to the Trustee, on the date hereof and each anniversary date thereafter, and at any other reasonable time if the Trustee so requests, a Certificate of the Corporation stating that the Corporation has complied with all covenants, conditions and other requirements contained in this Indenture, non-compliance with which would, with the giving of notice or the lapse of time or both, constitute an Event of Default hereunder or, if such is not the case, giving particulars as to each non-compliance and the action, if any, the Corporation proposes to take with respect thereto.

(2)

Upon the occurrence of an Event of Default, without the necessity of any further act or formality, but subject to applicable law, the security hereby created and created by the Security Agreement shall become enforceable.

- 35 -

Section 6.05

Enforcement by the Trustee

(1)

Subject to the provisions of Section 6.04 and Section 11.14 and to the provisions of any Extraordinary Resolution that may be passed by the Unitholders, in case the Corporation shall fail to pay to the Trustee, forthwith after the same shall have been declared to be due and payable under Section 6.03 hereof, the aggregate Remaining Royalty Entitlement on the Units then outstanding, together with any other amounts due thereunder, the Trustee may in its discretion and shall upon receipt of a Unitholders’ Request and being indemnified by the Corporation to its reasonable satisfaction against all costs, expenses and liabilities to be incurred and upon receiving such funds as it reasonably considers necessary as security for such indemnity, proceed in its name as Trustee hereunder to obtain or enforce payment of the said Remaining Royalty Entitlement on all the Units then outstanding together with any other amounts due thereunder by such proceedings authorized by this Indenture or by law or equity as the Trustee in such request shall have been directed to take, or if such request contains no such direction, or if the Trustee shall act without such request, then by such proceedings authorized by this Indenture or by suit at law or in equity as the Trustee shall deem expedient.

(2)

The Trustee shall be entitled and empowered, either in its own name or as trustee of an express trust, or as attorney-in-fact for the holders of the Units or in any one or more of such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the claim of the Trustee and of the holders of the Units allowed in any insolvency, bankruptcy, liquidation or other judicial proceedings relative to the Corporation or its creditors or relative to or affecting its property. The Trustee is hereby irrevocably appointed (and the successive respective holders of the Units by taking and holding the same shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective holders of the Units with authority to make and file in the respective names of the holders of the Units, subject to deduction from any such claims of the amounts of any claims filed by any of the holders of the Units themselves, any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any such other papers and documents and to do and perform any and all such acts and things for and on behalf of such holders of the Units as may be necessary or advisable in the opinion of the Trustee, in order to have the respective claims of the Trustee and of the holders of the Units against the Corporation or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that nothing contained in this Indenture shall be deemed to give to the Trustee, unless so authorized by Extraordinary Resolution, any right to accept or consent to any plan of reorganization or otherwise by action of any character in such proceeding to waive or change in any way any right of any Unitholder.

(3)

The Trustee shall also have the power at any time and from time to time to institute and to maintain such suits and proceedings as it may be advised shall be necessary or advisable to preserve and protect its interest and the rights of the holders of the Units.

(4)

All rights of action hereunder may be enforced by the Trustee without the possession of any of the Units or the production thereof on the trial or other proceedings relative thereto. Any such suit or proceeding instituted by the Trustee may be brought in the name of the Trustee as trustee of an express trust, and any recovery of judgment shall be for the rateable benefit of

- 36 -

the holders of the Units subject to the provisions of this Indenture. In any proceeding brought by the Trustee (and also any proceeding in which a declaratory judgment of a court may be sought as to the interpretation or construction of any provision of this Indenture, to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Units and it shall not be necessary to make any holders of the Units parties to any such proceeding.

(5)

The Corporation shall be liable to the Trustee for all costs incurred by the Trustee in connection with the enforcement of rights under this Indenture.

Section 6.06

Suits by Unitholders

No holder of any Unit shall have any right to institute any action, suit or proceeding at law or in equity for the purpose of enforcing payment of the aggregate Remaining Royalty Entitlement on the Units or for the execution of any trust or power hereunder or for the appointment of a liquidator or receiver or for a receiving order or to have the Corporation wound up or to file or prove a claim in any liquidation or bankruptcy proceeding or for any other remedy hereunder unless (1) such holder shall previously have given to the Trustee written notice of the happening of an Event of Default or a breach of one of the covenants of the Corporation provided for in Article V and such breach shall have continued unremedied for a period of 60 days; and (2) the holders of Units by a Unitholders’ Request to the Trustee have requested the Trustee to take such action (unless such request is subsequently rescinded by instrument in writing signed by the holders of a majority in number of the outstanding Units); and (3) the Corporation, as provided hereunder, has indemnified the Trustee against the costs, expenses and liabilities to be incurred therein or thereby; and (4) the Trustee shall have failed to act within 30 days after such notification, request and offer of indemnity. If any holder of a Unit shall, acting on behalf of himself and all other holders of Units, be entitled to institute any action or proceeding in accordance with this Section 6.06, the Corporation shall, in addition to the other moneys payable hereunder, pay to such holder if such action or proceeding is substantially successful the reasonable costs and expenses incurred in connection therewith.

Section 6.07

Application of Moneys by Trustee

(1)

Except as herein otherwise expressly provided, any moneys received by the Trustee from the Corporation pursuant to the foregoing provisions of this Article, or as a result of legal or other proceedings or from any trustee in bankruptcy or liquidator of the Corporation shall be applied, together with any other moneys in the hands of the Trustee available for such purposes, subject to Section 6.08 as follows:

(a)

For greater certainty, no payment shall be made pursuant to Section 6.07(1)(b) in respect of the Remaining Royalty Entitlement on any Units held, directly or indirectly, by or for the benefit of the Corporation or any of its Affiliates (other than any Unit pledged for value and in good faith to a Person other than the Corporation or any of its Affiliates, but only to the extent of such Person’s interest therein) except subject to the prior payment in full of the aggregate Remaining Royalty Entitlement on the Units which are not so held.

Section 6.08

Distribution of Proceeds

Payments to holders of Units pursuant to Section 6.07(1)(b) shall be made as follows:

(a)

at least 10 Business Days’ notice of every such payment shall be given in the manner provided in Section 10.02 specifying the time when and the place or places where the Units are to be presented and the amount of the payment;

(b)

payment of any Unit shall be made upon presentation thereof at any one of the places specified in such notice and any such Unit thereby paid in full shall be surrendered, otherwise a memorandum of such payment shall be endorsed thereon; but the Trustee may in its discretion dispense with presentation and surrender or endorsement in any special case upon such indemnity being given as it shall deem sufficient; and

(c)

the Trustee shall not be required to make any interim payment to Unitholders until the earlier of (i) the day the moneys in the Trustee’s hands, after reserving therefrom such amount as the Trustee may think necessary to provide for the payments mentioned in Section 6.07(1)(a), exceeds 5% of the Remaining Royalty Entitlement of the Units then outstanding, and (ii) the last Business Day of the calendar month in which the Event of Default occurs.

Section 6.09

Remedies Cumulative

No remedy herein conferred upon or reserved to the Trustee, or upon or to the holders of Units, is intended to be exclusive of any other remedy, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now existing or hereafter to exist by law or by statute.

Section 6.10

Judgment Against the Corporation

The Corporation covenants and agrees with the Trustee that, in case of any judicial or other proceeding to enforce the rights of the Unitholders, judgment may be rendered against it in favour of the Unitholders or in favour of the Trustee, as trustee for the Unitholders,

- 38 -

for any amount which may remain due in respect of the Units and any other moneys owing hereunder.

Section 6.11

No Waiver

No delay or omission of the Trustee or of the Unitholders to exercise any remedy referred to in Section 6.05 shall impair any such remedy or shall be construed to be a waiver of any Event of Default hereunder or acquiescence therein.
