               cash; or

               the case may be, in kind; and

     (b)  with respect to Other Metals, two per cent (2%) of the Gross Value of
          all Other Metals, in cash.

     If the Concessionaire incurs Incremental Costs, the Beneficiary will
     reimburse the Concessionaire for an amount equal to 2% of such Incremental
     Costs. The Beneficiary will pay its share of Incremental Costs, in respect
     of Royalty payments made in cash, by way of a deduction from such payment
     by the Payor prior to remittance to the Beneficiary and, in respect of
     Royalty payments made in kind, by way of a cash payment by the Beneficiary
     to or to the direction of the Concessionaire based upon the
     Concessionaire's invoice therefor.

2.2  If the Concessionaire sells raw ores principally valuable for their metal
     content or concentrates of precious metals or dore produced from ores mined
     or otherwise recovered from the Property then, for the purposes of
     calculating Gross Value, Gold Production, Silver Production and Other Metal
     Production will, in each case, be equal to the gold, silver and other
     metals contained in such raw ores, concentrates or dole sold in a specified
     month multiplied by,

     (b)  in the absence of a contractually determined recovery rate, an assumed
          recovery rate equal to the average actual recovery rate for such metal
          during



          beneficiation by or on behalf of the Concessionaire for the latest
          calendar quarter ended prior to such month in which ores of such metal
          from the Property were beneficiated by or on behalf of the
          Concessionaire.

     In the event that such ores have not been so beneficiated by or on behalf
     of the Concessionaire during any such calendar quarter, the recovery rate
     will be the actual recovery rate experienced by the purchaser of such ores,
     concentrates or dare determined in good faith by the Concessionaire.

2.3  The Royalty will be paid to the Beneficiary within thirty (30) days after
     the end of each calendar quarter in accordance with written instructions
     given to the Concessionaire's Refiner or the Concessionaire's Payer, as the
     case may be, by the Beneficiary as provided in Sections 2A and 2.5 below
     and once such Refiner or Payor, as the case may be, has received
     instructions from the Beneficiary, such instructions will remain in effect
     until the Refiner or Payor, as the case may be, has received different
     instructions from the Beneficiary. All contractual or other arrangements
     entered into by the Concessionaire with any Refiner or Payer will contain
     provisions implementing the terms and conditions of payment set forth in
     Sections 2.4 and 2.5 hereof. The Beneficiary may, from time to time in its
     discretion, change such payment instructions by giving written notice
     thereof to the Concessionaire and the Refiner or Payer, as the case may be,
     and such notice will be effective upon actual receipt by the recipient, or
     upon the tenth (10th) day after deposit of such notice in the mail, first
     class postage prepaid, whichever occurs first.

2.4  The Concessionaire will pay the Royalty in respect of Precious Metals as
     directed by the Beneficiary either:

     (a)  in kind, in the form of Refined Gold or Refined Silver, as the case
          may be, in which case the Concessionaire will irrevocably instruct the
          Refiner to pay the Royalty, in kind, directly to the Beneficiary's
          separate consignment account maintained with the Refiner as directed
          by the Beneficiary; or

     (b)  in cash, in which case the Concessionaire will irrevocably instruct
          the Payor to pay the Royalty, in cash, by delivery of a cheque, bank
          draft or wire transfer payable to the Beneficiary or as the
          Beneficiary may direct.

2.5  The Concessionaire will pay the Royalty in respect of all Other Metals in
     cash, in which case the Concessionaire will irrevocably instruct the Payor
     to pay the Royalty, in cash, by delivery of a cheque, bank draft or wire
     transfer payable to the Beneficiary or as the Beneficiary may direct.

2.6  All payments of the Royalty, whether in cash or in. kind, will be
     accompanied by a



                                       (v)


     detailed statement from the Refiner or Payer, as the case may be, or the
     Concessionaire explaining the manner in which the payment was calculated.
     In no event will payment of the Royalty be made later than the date
     specified in Section 2.3. Such payments and statements will be deemed
     conclusively correct unless the Beneficiary objects to them in writing
     within twelve (12) months after receipt thereof. In the event any Royalty
     payment is not made within the time provided in Section 2.3, the
     Beneficiary may give the Concessionaire notice in writing of such default
     and, unless within thirty (30) days of receipt of such notice the
     Beneficiary has received such Royalty payment, the Concessionaire will pay
     an. additional sum equal to ten percent (10%) of the delinquent payment
     ("late charge") plus interest on the delinquent payment at the prime rate
     charged by the Bank of Montreal (or its successors) on the day the
     delinquent payment was due. Interest will accrue from the day the
     delinquent payment was due to the date of payment of the Royalty payment,
     late charge and accrued interest.

3.   RECORDS AND CONFIDENTIALITY

3.1  The Concessionaire will keep true and accurate books and records of all of
     its operations and activities in respect of the Property. Such books and

     than annually the Beneficiary may, at the Beneficiary's sole expense,
     perform an audit or other examination of all of Concessionaire's books and
     records relating to the Royalty. All financial information will
     conclusively be deemed correct for purposes of the Royalty unless the
     Beneficiary has given timely notice that it desires to audit or examine
     Concessionaire's books and records relating to the Royalty based on an
     objection pursuant to Section 2.6. The Beneficiary will promptly commence
     any such audits and will diligently complete such audits in a timely
     manner.

3.2  The Beneficiary will not, without the express written consent of
     Concessionaire, which consent will not be unreasonably withheld, knowingly
     disclose to any third party any information obtained pursuant hereto which
     is not generally available to the public provided, however, that the
     Beneficiary may disclose data or information obtained hereunder without the
     consent of the Concessionaire:

     (a)  if required for compliance with applicable laws, rules, regulations or

          over the Beneficiary or its parent or affiliated corporations or
          companies;

     (b)  to any of the Beneficiary's consultants;

     (c)  to any third party to whom the Beneficiary, in good faith, anticipates

          Royalty; or

     (d)  to a prospective lender;



                                      (vi)

4.   MAINTENANCE OF PROPERTY

4.1  Subject to Section. 4.2 below, the Concessionaire will maintain its
     interest in the Property and perform all work or other matters necessary to

     requirements, policies and guidelines (collectively "Applicable Laws"). The
     Concessionaire will pay or use its best efforts to have paid all taxes and
     other payments when due on or with respect to the Property, and will do all
     things and make all payments necessary or appropriate to maintain the
     right, title and interest of Concessionaire and Beneficiary, respectively,
     in the Property.

4.2  The Concessionaire will in no. way be prohibited or in any way restricted
     from abandoning its interest in the Property if the Concessionaire
     concludes in its sole discretion that continued exploration, development or
     mining activities in respect of the Property are uneconomic or not in the
     best interests of the Concessionaire provided, however, that in the event
     Concessionaire intends to abandon any of its interests in the Property
     ("Abandonment Property"), the Concessionaire will first give notice of such
     intention to the Beneficiary at least forty-five (45) days in advance of
     the proposed date of abandonment. If the Concessionaire receives from the
     Beneficiary written notice not later than ten (10) days before the proposed
     date of abandonment that the Beneficiary desires the Concessionaire to
     convey the Abandonment Property to the Beneficiary, the Concessionaire will
     not abandon the Abandonment Property but will convey the Abandonment
     Property in good standing, without warranty, to the Beneficiary. Following
     such conveyance or, in the event the Beneficiary does not elect such
     conveyance and the Abandonment Property is abandoned, the Concessionaire
     will have no further obligations to maintain the title to or its interest
     in the Abandonment Property. Any action taken by the Concessionaire under
     this Section 4.2 will not affect the Concessionaire's obligations hereunder
     with respect to those portions of the Property not abandoned. The
     obligations of the Concessionaire under this Section 4.2 are subject to any
     provisions under the Tenures, Applicable Laws or any agreement affecting
     the Abandonment Property in effect on the date the Royalty is granted
