INFORMATION of the other party, whether disclosed prior to, or after the date
hereof, and further agrees not to use any such CONFIDENTIAL INFORMATION for any
purpose, except pursuant to, and in order to carry out, the terms and objectives
of this Agreement, provided that each party may disclose CONFIDENTIAL
INFORMATION of the other party to the officers, directors, employees, agents,
consultants, permitted subcontractors or other representatives of the receiving
party or its AFFILIATES (the "Representatives"), who, in each case, need to know
such CONFIDENTIAL INFORMATION for purposes of the implementation and performance
by the receiving party of this Agreement and will use such CONFIDENTIAL
INFORMATION only for such limited purposes.

8.2     Each party agrees to use at least the same standard of care as it uses
to protect proprietary or CONFIDENTIAL INFORMATION of its own of comparable
sensitivity and to exercise every reasonable precaution to prevent and restrain
the unauthorized disclosure of such CONFIDENTIAL INFORMATION by any of its
Representatives.

8.3     Each party warrants that each of its Representatives to whom any
CONFIDENTIAL INFORMATION is revealed shall previously have been informed of the
confidential nature of the CONFIDENTIAL INFORMATION and shall have agreed to be
bound by the terms and conditions of this Article 8 applicable to the receiving
party.

8.4     The provisions of Section 8.1 shall not apply to any CONFIDENTIAL
INFORMATION disclosed hereunder which:
        a)      was known by the receiving party prior to its disclosure to the
receiving party by the other party, as evidenced by the prior written records of
the receiving party; or

<Page>

        b)      either before or after the date of disclosure to the receiving
party by the other party is lawfully disclosed to receiving party by an
independent, unaffiliated third party rightfully in possession of the
CONFIDENTIAL INFORMATION, provided that disclosure and use is in conformity with
the obligations of confidentiality and non-use imposed by such third party; or
        c)      either before or after the date of disclosure to the receiving
party by the other party becomes published or generally known to the public
through no fault or omission on the part of the receiving party or its
Representatives; or
        d)      is developed independently by the receiving party without use of
CONFIDENTIAL INFORMATION of the other party, as evidenced by the written records
of the receiving party; or
        e)      is required to be disclosed by the receiving party to comply

prior written notice of such disclosure to the other party and takes reasonable
and lawful actions to avoid and/or minimize the degree of such disclosure.

8.5     Notwithstanding anything herein to the contrary, the parties agree that
disclosure and use by MOMENTA or SIEGFRIED of CONFIDENTIAL INFORMATION of the
other party pursuant to any of the licenses granted in Sections 7.6 through 7.8

valid subpoena or other judicial order, neither party shall disclose the terms

and attorneys, provided any such attorney or accountant agrees to be bound by
the confidentiality obligations of this Section 8.6.

8.7     Except as otherwise set forth in this Agreement, nothing herein shall be
construed as giving either party any right, title, interest in or ownership of
the CONFIDENTIAL INFORMATION of the other party. For the purposes of this
Agreement, any specific item disclosed as part of CONFIDENTIAL INFORMATION shall
not be deemed to be in the public domain or in the prior possession of the
receiving party merely because it is embraced by more general information in the
public domain or by more general information in the prior possession of the
receiving party.

Article 8 shall remain binding on both parties during the term of this Agreement

written notice to the other party upon the occurrence of any of the following
events:

<Page>

        a)      the other party breaches a material obligation of this Agreement
and, after written notification from the non-breaching party, fails to remedy
the breach within fifteen (15) days of such written notification; or
        b)      either party reasonably determines that, for valid scientific or
technical reasons, the goals for the DEVELOPMENT or PRODUCTION cannot be
achieved within the parameters or timelines agreed to in Appendices B and E and
the parties cannot agree on a modification of such goals, parameters or
timelines within thirty (30) days of the date of the determination, it being
understood that each party shall be obligated to use good faith efforts to agree
on as minimal a modification of such goals, parameters or timelines as is
reasonably required by the scientific or technical obstacle; or
        c)      solely to the extent permitted by law, the other party opens
bankruptcy proceedings, goes into receivership, or allows its creditors to place
the company in receivership.

9.3     MOMENTA may terminate this Agreement, at any time, upon the giving of
thirty (30) days prior written notice to SIEGFRIED.

9.4     Upon any termination of this Agreement, the parties shall determine the
total amount of (a) the cost of all raw materials purchased by SIEGFRIED for
purposes of DEVELOPMENT and PRODUCTION plus (b) a reasonable estimate of the
cost of the labor associated with the proportion of the DEVELOPMENT and
PRODUCTION performed up to the date of the determination in the case of a
termination pursuant to clause (b) of Section 9.2 or up to the date of the
termination in the case of all other terminations of this Agreement (the "Actual
Cost"). For purposes of the foregoing calculation, fifty percent (50%) of the
fee set forth in Section 10.1 shall be attributed to the DEVELOPMENT and fifty
percent (50%) of the fee set forth in Section 10.1 shall be attributed to the
PRODUCTION. In the event of a termination by MOMENTA pursuant to clause (b) of
Section 9.2 or Section 9.3 or a termination by SIEGFRIED, subject to SIEGFRIED's
compliance with Section 3.3, SIEGFRIED shall be entitled to retain or receive
the Actual Cost. In determining whether an actual payment shall be due SIEGFRIED
from MOMENTA, all amounts previously paid by MOMENTA pursuant to Section 10.1
for DEVELOPMENT and PRODUCTION shall be taken into account. In the event that
MOMENTA shall have previously paid SIEGFRIED an amount greater than the Actual
Cost, SIEGFRIED shall pay MOMENTA an amount equal to the difference between the
amount previously paid by MOMENTA and the Actual Cost. In the event of a
termination by MOMENTA pursuant to clause (a) or (c) of Section 9.2, SIEGFRIED
shall not be entitled to any further payments from MOMENTA but, subject to
SIEGFRIED's compliance with Section 3.3, shall be entitled to retain all amounts
previously paid by MOMENTA pursuant to Section 10.1 for DEVELOPMENT and
PRODUCTION unless MOMENTA shall have previously paid SIEGFRIED an amount greater
than the Actual Cost. In any such case, SIEGFRIED shall pay MOMENTA an amount
equal to the difference between the amount previously paid by MOMENTA and the
Actual Cost.

9.5     All rights and obligations as set forth in Sections 3.3, 5.2, 7.1, 7.2,
7.3, 7.4, 7.5, 7.7, 7.8, 7.9, 9.4, 13.3, 13.4 and 13.5 and Articles 8 and 12
shall continue irrespective of any expiration or termination of this Agreement.

9.6     The waiver by the parties of any breach, covenant or condition herein
contained shall not be deemed to be a waiver of any subsequent breach of the
same or any other term, covenant or condition herein.

<Page>

10.     PAYMENT AND DELIVERIES

10.1    MOMENTA shall pay SIEGFRIED a total fee of Four Hundred Twenty-Five
Thousand U.S. Dollars ($425,000) for the DEVELOPMENT and PRODUCTION. Such fee
shall become due in accordance with the timetable set forth in Appendix D.
SIEGFRIED shall invoice MOMENTA as payments become due and MOMENTA shall pay
such invoices within thirty (30) days thereafter.

10.2    If, during the course of DEVELOPMENT, it becomes reasonably apparent to
SIEGFRIED that (a) circumstances exist which could not have been foreseen by the
parties or which were excluded from the assumptions made by both parties in
agreeing to the fee set forth in Section 10.1 and (b) such circumstances render
the completion of the DEVELOPMENT and PRODUCTION materially more costly than had
been foreseen by the parties, SIEGFRIED shall notify MOMENTA in writing. Upon
receipt of such notification, the parties shall use good faith efforts to agree
on as minimal a modification of the fee set forth in Section 10.1 as is
reasonably required by the unforseen or changed circumstance. If the parties
agree on an associated increase in cost, SIEGFRIED shall proceed with the
DEVELOPMENT and PRODUCTION. If the parties do not agree on an associated
increase in cost, SIEGFRIED shall have the right to proceed with DEVELOPMENT and
PRODUCTION or treat the circumstances as a technical obstacle and terminate this
Agreement in accordance with clause (b) of Section 9.2.

10.3    Delivery of ENOXAPARIN and PRODUCT shall be "ex works PENNSVILLE, NEW
JERSEY" as defined in the current INCOTERMS.

11.     SUBCONTRACTING

11.1    SIEGFRIED shall not be entitled to engage any subcontractor for the
DEVELOPMENT or the PRODUCTION without the prior written consent of MOMENTA. If a
subcontractor is appointed, SIEGFRIED shall be responsible for all work
performed by such subcontractor. The parties acknowledge in advance that
SIEGFRIED does not have the in-house capability to assay for certain biological
activities for quality control purposes, and that MOMENTA and SIEGFRIED will
mutually agree on appropriate third party subcontractors to conduct such assays
on behalf of SIEGFRIED.

11.2    In the event that MOMENTA requests a modification of the process
pertaining to the DEVELOPMENT of ENOXAPARIN or the PRODUCTION of PRODUCT for
which SIEGFRIED believes the expertise of a subcontractor is reasonably
necessary and MOMENTA is unwilling to approve such a subcontractor, SIEGFRIED
shall have the right to treat such refusal as a technical obstacle and terminate
this Agreement pursuant to clause (b) of Section 9.2.

11.3    MOMENTA shall be entitled to join any audit conducted by SIEGFRIED of a
supplier of raw material or of a subcontractor.

12.     WARRANTIES

12.1    Each party represents and warrants that, as of the effective date of
this Agreement, it is not a party to any agreement, contract, arrangement or the
like with any third party, or under any obligation or restriction, including,
without limitation, pursuant to its charter documents or by laws, which in any
way limits or conflicts with its ability to fulfill any of its obligations under
this Agreement.

<Page>

12.2    SIEGFRIED makes no representation or warranty that the processes used in
developing or producing ENOXAPARIN or PRODUCT or that the production, use or
importation of ENOXAPARIN or PRODUCT, would not infringe any patent or other
proprietary right belonging to a third party. Notwithstanding the foregoing,
SIEGFRIED represents and warrants to MOMENTA that, as of the effective date of
this Agreement, it has not received any notice from any third party that the
practice of the SIEGFRIED IP infringes any patent or other proprietary rights of
any third party and SIEGFRIED has no knowledge of any third party patent or
proprietary rights that might be infringed by the practice of the SIEGFRIED IP.
Further, SIEGFRIED represents and warrants to MOMENTA that it will not knowingly
use any infringing or misappropriated SIEGFRIED IP in the DEVELOPMENT or
PRODUCTION.

13.     PRODUCT QUALITY, INDEMNIFICATION AND INSURANCE

13.1    In the case of a material error by SIEGFRIED which results in an
inability to achieve the goals for the DEVELOPMENT or PRODUCTION within the
parameters or timelines agreed to in Appendices B and E, SIEGFRIED shall inform
MOMENTA immediately and exercise diligent efforts to correct the error so that
the goals for the DEVELOPMENT and PRODUCTION are achieved within the parameters
agreed to in Appendix B as soon as possible thereafter.

13.2    In the event that MOMENTA believes it is justified in rejecting PRODUCT
because it does not meet the requirements of Section 2.5, MOMENTA shall inform
SIEGFRIED accordingly with a written notice delivered within forty-five (45)
days from the date of receiving the PRODUCT. In any such case, the parties shall
repeat the disagreed upon sampling and analysis. Should MOMENTA still believe it
is justified in rejecting the PRODUCT following such repeated sampling and
analysis, MOMENTA shall have the right to engage an independent third party to
perform the disagreed upon sampling and analysis. Should the results show that
the PRODUCT does not meet the requirements of Section 2.5, SIEGFRIED shall
exercise diligent efforts to replace the PRODUCT as soon as possible thereafter
and shall be responsible for the cost of the replacement raw materials (other
than the heparin) and the sampling and analysis conducted by the independent
third party.

13.3    MOMENTA shall, at all times during the term of this Agreement and
thereafter, indemnify, defend and hold harmless SIEGFRIED, and its directors,
officers, employees and AFFILIATES (the "Other SIEGFRIED Indemnified Parties"),
from and against any and all third party product liability claims, proceedings,
demands and liabilities, of any kind whatsoever, including legal expenses and
reasonable attorneys' fees, arising out of the death of or injury to any person
or out of any damage to property resulting from the production, use or
consumption of any ENOXAPARIN or PRODUCT developed or produced pursuant to this
Agreement, excluding any such losses resulting from the failure of the PRODUCT
to meet the requirements of Section 2.5 or the negligence or misconduct of
SIEGFRIED.

13.4    SIEGFRIED shall, at all times during the term of this Agreement and
thereafter, indemnify, defend and hold harmless MOMENTA, and its directors,
officers, employees and AFFILIATES (the "Other MOMENTA Indemnified Parties"),
from and against any and all third party product liability claims, proceedings,
demands and liabilities, of any kind whatsoever, including legal expenses and
reasonable attorneys' fees, arising out of the death of or injury to any person
or out of any damage to property resulting from the production, use or
consumption of any ENOXAPARIN or PRODUCT developed or produced pursuant to this
Agreement where

<Page>

such losses result from the failure of the PRODUCT to meet the requirements of
Section 2.5 or the negligence or misconduct of SIEGFRIED.

13.5    Prior to the first use in humans of any ENOXAPARIN or PRODUCT developed
or produced pursuant to this Agreement, each party shall obtain and carry in
full force and effect commercial general liability insurance, including clinical
trial product liability insurance, which shall protect the other party with
respect to events covered by Sections 13.3 and 13.4. Such insurance shall be
written by a reputable insurance company authorized to do business in the United
States of America, shall list the other party as an additional named insured
thereunder, and shall require thirty (30) days written notice to be given to the
other party prior to any cancellation or material change thereof. The limits of
such insurance shall not be less than one million dollars ($1,000,000) per
occurrence with an aggregate of three million dollars ($3,000,000) for personal
injury, including death, and one million dollars ($1,000,000) per occurrence
with an aggregate of three million dollars ($3,000,000) for property damage.
Each party shall provide the other party with a certificate of insurance
evidencing the same.

13.6    MOMENTA shall, at all times during the term of this Agreement and
thereafter, indemnify, defend and hold harmless SIEGFRIED and the Other
SIEGFRIED Indemnified Parties, from and against any and all third party
liability claims, proceedings, demands and liabilities, of any kind whatsoever,
including legal expenses and reasonable attorneys' fees, arising out of any
alleged infringement of any patent or other intellectual property right held by
a third party in connection with the DEVELOPMENT or PRODUCTION or the use or
importation of any ENOXAPARIN or PRODUCT developed or produced pursuant to this
Agreement, excluding any such losses resulting from a breach by SIEGFRIED of the
representation and warranty set forth in Section 12.2.

13.7    SIEGFRIED shall, at all times during the term of this Agreement and
thereafter, indemnify, defend and hold harmless MOMENTA and the Other MOMENTA
Indemnified Parties, from and against any and all third party liability claims,
proceedings, demands and liabilities, of any kind whatsoever, including legal
expenses and reasonable attorneys' fees, arising out of any alleged infringement
of any patent or other intellectual property right held by a third party in
connection with the DEVELOPMENT or PRODUCTION or the use or importation of any
ENOXAPARIN or PRODUCT developed or produced pursuant to this Agreement where
such losses resulting from a breach by SIEGFRIED of the representation and
warranty set forth in Section 12.2.

13.8    If party or any of its associated indemnified parties intends to claim
indemnification under this Article 13, such party shall promptly notify the
other party in writing of the action, claim or other matter in respect of which
such party or any of its associated indemnified parties intends to claim such
indemnification. Such party shall permit, and, in order for any of its
associated indemnified parties to be indemnified pursuant to this Article 13,
shall cause such associated indemnified parties to permit, the other party to
solely control the defense and/or settlement of such action, claim or other
matter. No such action, claim or other matter shall be settled by such party or
any of its associated indemnified parties without the prior written consent of
the other party. Such party and its associated indemnified parties who seek to
be indemnified pursuant to this Article 13 shall fully cooperate with the other
party and its legal representatives in the investigation and defense of any
action, claim or other matter covered by the indemnification obligations of this
Article 13. Such party and its associated indemnified parties shall have the
right, but not the obligation, to be represented in such defense by counsel of
their own selection and at their own expense.

<Page>

13.9    In the event a claim is based partially on an indemnified claim and
partially on a non-indemnified claim, or based partially on a claim indemnified
by one party and partially on a claim indemnified by the other party, any
payments in connection with such claims are to be apportioned between the
parties in accordance with the degree of cause attributable to each party.

Agreement, the execution of this Agreement, and the interpretation of the terms
of this Agreement shall be the English language.

14.2    Neither this Agreement, nor any of the rights or obligations hereunder,

shall be null and void and of no effect.

14.3    Either party shall be excused from performing its obligation under this
Agreement if its performance is delayed or prevented by any cause beyond such
party's control, including but not limited to, act of God, fire, explosion,
weather, disease, war, insurrection, civil strife, riots, government action, or
power failure. Performance shall be excused only to the extent of and during the
reasonable continuance of such disability. Any deadline or time for performance
specified in an appendix to this Agreement that falls due during or subsequent

other party, and neither party will have authority to speak for, represent or
obligate the other party in any way without prior written authority from the
other party.

14.5    This Agreement and the appendices to this Agreement, which appendices
are deemed to be a part of this Agreement for all purposes, contain the full
understanding of the parties with respect to the subject matter hereof and
supersede all prior understandings and writings relating thereto. No waiver,
alteration or modification of any of the provisions hereof shall be binding
unless made in writing and signed by the parties.

14.6    In the event that any term of this Agreement shall violate any
applicable statute, ordinance or rule of law in any jurisdiction in which it is
used, or otherwise be unenforceable, such provision shall be ineffective to the
extent of such violation without invalidating any other provision hereof.

14.7    Each party represents and warrants to the other that it has the legal
power, authority and right to enter into this Agreement and to perform its
respective obligations set forth herein. This Agreement has been duly executed
and delivered by each party and constitutes the valid and binding obligation of
such party, enforceable against such party in accordance with its terms.

Dear Scott:

Reference is made to the Development and Production Agreement for Active
Pharmaceutical Ingredient between Siegfried (USA), Inc. and Siegfried Ltd.
("SIEGFRIED") and Momenta Pharmaceuticals, Inc. ("MOMENTA") dated October 10,
2003 (the "Agreement"). Capitalized terms used herein and not otherwise defined
shall have the meanings given such terms in the Agreement.

MOMENTA hereby engages SIEGFRIED to undertake the additional development work
set forth on Appendix A to this Letter Agreement (the "ADDITIONAL DEVELOPMENT
WORK"). The ADDITIONAL DEVELOPMENT WORK shall be conducted under the terms and
conditions of the Agreement, with the following modifications:

     1.   SIEGFRIED shall use commercially diligent efforts to undertake the
          ADDITIONAL DEVELOPMENT WORK with the goal of completing the work
          within [**] of initiation of the work.

     2.   MOMENTA shall pay SIEGFRIED a total fee of Two Hundred Thousand
          U.S. Dollars ($200,000) for the ADDITIONAL DEVELOPMENT WORK. Fifty
          percent (50%) of such fee shall be due and payable upon initiation
          of the work and the remaining Fifty percent (50%) shall be due and
          payable upon the issuance of a final development report by SIEGFRIED
          which is reasonably satisfactory to MOMENTA. Invoicing and payment
          shall be in accordance with Section 10.1 of the Agreement. For
          purposes of Section 9.4 of the Agreement, the foregoing fee shall be
          attributed to the ADDITIONAL DEVELOPMENT WORK.

     3.   MOMENTA shall be responsible for supplying the necessary quantities of

          ENOXAPARIN and/or PRODUCT to be undertaken by SIEGFRIED under the
          Agreement.

If the foregoing is in conformity with your understanding, please execute both
copies of this Letter Agreement and return one fully-executed copy to me.

                             Very truly yours,

      an intended offer by the Optionor, disclose the person or persons to whom
      the Optionor intends to offer its interest and, if the offer received by
      the Optionor from the Proposed Purchaser provides for any consideration
      payable to the Optionor otherwise than in cash, the Offer shall include
      the Optionor's good faith estimate of the cash equivalent of the non-cash
      consideration. 
	 	 	 	 
	 	 	 (iii)      	 If within a period of 60 days of the receipt of the Offer the
      Optionee notifies the Optionor in writing that it will accept the Offer,
      the Optionor 

 9

	 	 	 	shall be bound to sell such interest to the Optionee on the
      terms and conditions of the Offer. If the Offer so accepted by the Optionee
      contains the Optionor's good faith estimate of the cash equivalent of the
      non cash consideration as aforesaid, and if the Optionee disagrees with
      the Optionor's best estimate, the Optionee shall so notify the Optionor
      at the time of acceptance and the Optionee shall, in such notice, specify
      what it considers, in good faith, the fair cash equivalent to be and the
      resulting total purchase price. If the Optionee so notifies the Optionor,
      the acceptance by the Optionee shall be effective and binding upon the Optionor
      and the Optionee, and the cash equivalent of any such non-cash consideration
      shall be determined by binding arbitration and shall be payable by the Optionee,
      subject to prepayment as hereinafter provided, within 60 days following
      its determination by arbitration. The Optionee shall in such case pay to
      the Optionor, against receipt of an absolute transfer of clear and unencumbered
      title to the interest of the Optionor being sold, the total purchase price
      which is specified in its notice to the Optionor and such amount shall be
      credited to the amount determined following arbitration of the cash equivalent
      of any non-cash consideration. 
	 	 	 	 
	 	 	 (iv)      	 If the Optionee fails to notify the Optionor before the expiration
      of the time limited therefor that it will purchase the interest offered,
      the Optionor may sell and transfer such interest to the Proposed Purchaser
      at the price and on the terms and conditions specified in the Offer for
      a period of 60 days, but the terms of this paragraph shall again apply to
      such interest if the sale to the Proposed Purchaser is not completed within
      such 60 days. 
	 	 	 	 
	 	    	 (v)      	 Any sale hereunder shall be conditional upon the Proposed Purchaser
      delivering a written undertaking to the Optionee, in form and substance
      satisfactory to its counsel, to be bound by the terms and conditions of
      this Agreement. 

SURRENDER OF PROPERTY INTERESTS PRIOR TO TERMINATION OF AGREEMENT

 12.           The Optionee
  may at any time during the Option Period elect to abandon any one or more of
  the mineral claims comprised in the Property by giving notice to the Optionor

  laws of the jurisdiction in which they are situate for at least 12 months from
  the date of abandonment. Upon any such abandonment, the mineral claims so abandoned
  shall for all purposes of this Agreement cease to form part of the Property
  and, if title to such claims has been transferred to the Optionee the Optionee
  shall retransfer such title to the Optionor at the Optionee's expense. 

FORCE MAJEURE

	 13.      	(a)	 If the Optionee is at any time either during the Option Period

      fuel shortages, fires, wars, acts of God, governmental regulations restricting
      normal operations, 

 10

	 	 	shipping delays or any other reason or reasons, other than lack
      of funds, beyond the control of the Optionee, the time limited for the performance

      of time equal in length to the period of each such prevention or delay,
      but nothing herein shall discharge the Optionee from its obligations hereunder
      to maintain the Property in good standing;
	 	 	 
	 	 (b)      	 The Optionee shall give prompt notice to the Optionor of each
      event of force majeure and upon cessation of such event shall furnish to
      the Optionor with notice to that effect together with particulars of the
      number of days by which the obligations of the Optionee hereunder have been
      extended by virtue of such event of force majeure and all preceding events
      of force majeure. 
	 	 	 
	 	 (c)      	 After the Commencement of Commercial Production, the Optionee
      shall work, mine and operate the Property during such time or times as the
      Optionee in its sole judgment considers such operations to be profitable.
      The Optionee may suspend or curtail operations, both before and after Commencement
      of Commercial Production, during periods when the products derived from
      the Property cannot be profitably sold at prevailing prices or if an unreasonable
      inventory thereof, in the Optionee's sole judgment, has accumulated or would
      otherwise accumulate. 

CONFIDENTIAL INFORMATION

 14.           No information
  furnished by the Optionee to the Optionor hereunder in respect of the activities
  carried out on the Property by the Optionee, or related to the sale of minerals,
  ore, bullion or other product derived from the Property, shall be published
  or disclosed by the Optionor without the prior written consent of the Optionee,
  but such consent in respect of the reporting of factual data shall not be unreasonably
  withheld, and shall not be withheld in respect of information required to be
  publicly disclosed pursuant to applicable securities or corporation laws, regulations
  or policies. 

ARBITRATION

	 15.      	(a) 	 All questions or matters in dispute under this Agreement shall
      be submitted to arbitration pursuant to the terms hereof. 
	 	 	 

	 	 (b)      	 It shall be a condition precedent to the right of any party
      to submit any matter to arbitration pursuant to the provisions hereof, that
      any party intending to refer any matter to arbitration shall have given
      not less than 10 days' prior notice of its intention to do so to the other
      party, together with particulars of the matter in dispute. On the expiration
      of such 10 days, the party who gave such notice may proceed to refer the
      dispute to arbitration as provided in paragraph (c). 
	 	 	 
	 	 (c)      	 The party desiring arbitration shall appoint one arbitrator,
      and shall notify the other party of such appointment, and the other party
      shall, within 15 days after receiving such notice, either consent to the
      appointment of such arbitrator which shall then carry out the arbitration
      or appoint an arbitrator, and the two arbitrators so named, before proceeding
      to act, shall, within 30 days of the appointment of 

11

	 	the last appointed arbitrator, unanimously agree on the appointment
      of a third arbitrator to act with them and be chairman of the arbitration
      herein provided for. If the other party shall fail to appoint an arbitrator
      within 15 days after receiving notice of the appointment of the first arbitrator,
      the first arbitrator shall be the only arbitrator. If the two arbitrators
      appointed by the parties shall be unable to agree on the appointment of
      the chairman, the chairman shall be appointed under the provisions of the
      Commercial Arbitration Act of British Columbia. Except as specifically
      otherwise provided in this section, the arbitration herein provided for
      shall be conducted in accordance with such Act. The chairman, or in the
      case where only one arbitrator is appointed, the single arbitrator, shall
      fix a time and place in Vancouver, British Columbia, for the purpose of
      hearing the evidence and representations of the parties, and he shall preside
      over the arbitration and determine all questions of procedure not provided
      for under such Act or this section. After hearing any evidence and representations
      that the parties may submit, the single arbitrator, or the arbitrators,
      as the case may be, shall make an award and reduce the same to writing,
      and deliver one copy thereof to each of the parties. The expense of the
      arbitration shall be paid as specified in the award. 
	 	 
	 (d)      	 The parties agree that the award of a majority of the arbitrators,
      or in the case of a single arbitrator, of such arbitrator, shall be final
      and binding upon each of them. 
	 	 

DEFAULT

 16.           If at any
  time during the Option Period the Optionee is in default of any provision in
  this Agreement (other than the provisions of subparagraph 4(b) for which no
  notice of default need be given), the Optionor may terminate this Agreement,
  but only if: 

	 	 (a)      	 it shall have first given to the Optionee a notice of default
      containing particulars of the obligation which the Optionee has not performed,
      or the warranty breached; and 
	 	 	 
	 	 (b)      	 the Optionee has not, within 45 days following delivery of
      such notice of default, cured such default or commenced proceedings to cure
      such default by appropriate payment or performance, the Optionee hereby
      agreeing that should it so commence to cure any default it will prosecute
      the same to completion without undue delay. 

                  Should
  the Optionee fail to comply with the provision of subparagraph (b), the Optionor
  may thereafter terminate this Agreement by giving notice thereof to the Optionee.

TERMINATION OF MINING OPERATIONS

 17.           The Optionee
  may permanently discontinue mining operations on the Property at any time after
  the Commencement of Commercial Production when in its opinion no further mining
  operations can be economically carried out thereon. At such time, the Optionee
  shall dispose of all mining plant and equipment used on the Property, effect
  all reclamation work as required by law,

12

and otherwise dispose of the Property as it thinks fit.  Any purchaser of the Property after termination of mining operations on the Property shall take the Property free and clear of all claims by the Optionor. The accounts of the Optionee relating
to its mining operations on the Property shall be audited by the auditors of the Optionee as soon as practicable after the sale or disposition of all mining plant, equipment and the Property, and completion of reclamation. Final settlement of any
Royalty payable shall be effected without delay after receipt of the final audited statements. After receipt of such final audited statements and payment of Royalty, if any, this Agreement and the mutual obligations of the Optionee and the Optionor
hereunder shall terminate. 

RULE AGAINST PERPETUITIES 

 18.           If any right,
  power or interest held by or to be acquired by any party in the Property under
  this Agreement would violate the rule against perpetuities, then such right,
  power or interest shall terminate after the death of the last survivor of all
  the lineal descendants of Her Majesty, Queen Elizabeth II of England, living
  on the date of the execution of this Agreement.

  demand or other communication required or permitted to be given under this Agreement
  shall be in writing and shall be delivered, telegraphed or telecopied to such
  party at the address for such party specified above. The date of receipt of
  such notice, demand or other communication shall be the date of delivery thereof

 7.4           
  The Operator shall have the sole and exclusive right and authority to manage
  and carry out all Mining Operations and to enter into contracts and sub-contracts
  on behalf of the Joint Operation with third parties in respect thereof and incur
  the Costs required for that purpose. In so doing the Operator shall, unless

        are in accordance with accounting principles generally accepted in the
        mining industry in Canada;

	 	 
	(g)	perform its duties and obligations hereunder
        in a sound and workmanlike manner in accordance with sound mining and

        rules and regulations and this Agreement; and

	 	 
	(h)	prepare and submit draft Programs for
        each calendar year for consideration by the Management Committee by the

 8.            
  EXPLORATION PROGRAMS 

 8.1           Draft
  Programs submitted by the Operator to the Management Committee shall contain
  a statement in reasonable detail of the proposed Program and estimates of all
  Exploration Costs to be incurred. 

 10 

 8.2           
  The Management Committee shall review the draft Program prepared and, if it
  deems fit, adopt the same with such modifications, if any, as the Management
  Committee deems necessary. The Operator shall be entitled to an allowance for
  a Cost overrun of 10% of a Program budget and any Costs so incurred shall be
  deemed to be included in the Program. 

 8.3           
  The Operator shall forthwith submit the approved Program to the Parties. Each
  Party may, within 30 days of receipt of the Program, give notice to the Operator
  committing to contribute its Proportionate Share of the Exploration Costs on
  that Program. A Party which fails to give notice within the 30 day period shall
  be deemed to have elected not to contribute. 

 8.4           
  If any party elects or is deemed to have elected not to contribute to an approved
  Program the amounts to be contributed by the Participants who elected to contribute
  to that Program shall be increased pro rata, subject to the right
  of any of them to elect not to contribute more than the amount initially committed
  by them. If a Participant elects not to contribute more than the amount initially
  committed the Operator may elect not to proceed with the approved Program or
  may prepare an amended Program and the provisions of this Article shall apply
  to such amended Program. 

 8.5           
  The Operator shall be entitled to invoice each Participant: 

	(a)	no more frequently than monthly for
        its Proportionate Share of Exploration Costs incurred and paid by the
        Operator; or

	 	 
	(b)	in advance of requirements but not more
        than 30 days for an advance of that Participant's Proportionate Share
        of Exploration Costs.

 Each invoice shall be signed by some responsible official
  of the Operator. Each Participant shall pay to the Operator the amount invoiced
  within 30 days of receipt of the invoice. If a Participant protests the correctness
  of an invoice it shall nevertheless be required to make the payment subject
  to later adjustment if such protest is sustained. 

 8.6           
  If after electing to participate any Participant (the "Defaulting Party") fails
  to pay its Proportionate Share within the 30 day period referred to in Paragraph
  8.5 the Operator may by notice demand payment. If no payment is made within
  the period of 30 days next succeeding the receipt of the demand notice the Interest
  of the Defaulting Party shall be deemed to be less than 10% and that interest
  will be converted to a 5% Net Profits Royalty to be calculated and paid in accordance
  with Appendix II hereto, and that Party shall have no further Interest. The
  Interests of the other Parties shall be increased pro rata. 

 8.7           The
  Operator shall expend all monies advanced by a Participant ratably with the
  advances of the other Participants. If the Operator suspends or prematurely
  terminates a Program any funds advanced by a Participant in excess of that Participant's
  Proportionate Share of Exploration Costs incurred prior to the suspension or
  premature termination shall be refunded forthwith. 

 8.8           
  If any Program is altered, suspended or terminated prematurely so that the 

 11 

 Exploration Costs incurred on that Program as altered, suspended
  or terminated are less than 80% of the Exploration Costs originally proposed,
  any Party which elected or which is deemed to have elected not to contribute
  its Proportionate Share of the Exploration Costs incurred on that Program shall
  be given notice of the alteration, suspension or termination by the Operator
  and shall be entitled to contribute its Proportionate Share of the Exploration
  Costs incurred on that Program by payment thereof to the Operator within 30
  days after receipt of the notice. If payment is not made by that Party within
  the 30 days aforesaid it shall, without a demand for payment being required
  to be made thereafter by the Management Committee, forfeit its right to contribute
  to that Program. 

 8.9           
  If a Party elects or is deemed to have elected not to contribute to the Exploration
  Costs of any Program the Interest of that Party shall be decreased and the Interest
  of each Participant contributing in excess of its Proportionate Share of the
  Exploration Costs shall be increased so that at all times during the Exploration
  Period the Interest of each Party will be equal to its Exploration Costs and
  Prior Exploration Costs expressed as a percentage of the Exploration Costs and
  Prior Exploration Costs of all Parties. The party whose Interest has been reduced
  shall be entitled to receive details of and to contribute to future Programs
  to the extent of its then Interest. 

 8.10          
  If a Party's Interest is reduced to 10% or less, that Interest will be converted
  to a 5% Net Profits Royalty to be calculated and paid in accordance with Appendix
  II hereto, and that Party shall have no further Interest. The Interests of the
  other Parties shall be increased pro rata. 

 8.11          
  If the Operator fails to submit a draft Program for an Operating Year by November
  30 of the year preceding such Operating Year: 

	(a)	the Operator shall not be entitled to
        submit a draft Program for the Operating Year;

	 	 
	(b)	the other Party, and if there is more
        than one, the Party with the greatest Interest, may submit a draft Program
        (the "Non-Operator's Program") for the Operating Year for consideration
        by the Management Committee;

	 	 
	(c)	the Management Committee shall review
        the Non-Operator's draft Program and, if it deems fit (the Operator not
        being entitled to vote with respect thereto), adopt the Program with such
        modifications, if any, as the Management Committee deems necessary and
        the adopted Program shall then be submitted to the parties according to
        this Article;

	 	 
	(d)	if the Operator is a Party and elects
        not to contribute to the Program it shall cease to be the Operator and
        the Management Committee shall appoint a new Operator (the former Operator
        not being entitled to vote with respect thereto).

 8.12          If
  the Management Committee for any reason fails to adopt a Program for an Operating
  Year by December 31 of the preceding year, the Operator shall, subject to direction
  to the contrary by the Management Committee and the receipt of the necessary
  funds, carry out such work and make such disbursements as to meet the minimum
  requirements to maintain the Property in good standing. 

 12

 9.            
  FEASIBILITY REPORT 

 9.1           
  A Feasibility Report shall only be prepared with the approval of the Management
  Committee. The Operator shall provide copies of the completed Feasibility Report
  to each of the Parties forthwith upon receipt. 

 9.2           
  The Management Committee shall meet at reasonable intervals and times to review
  the Feasibility Report and discuss whether the establishing of a Mine and bringing
  the Property into Commercial Production in accordance with the Feasibility Report
  is feasible or desirable. 

 9.3           
  If the Operator has not provided copies of a completed Feasibility Report to
  each of the Parties with an Interest by the fifth anniversary of this Agreement,
  any Party whose Interest is not less than 20% and if there is more than one,
  the Party with the greatest Interest, may prepare a Feasibility Report at its
  own expense (the "Non-Operator's Feasibility Report") and submit it to the Management
  Committee. 

 10.          
  PRODUCTION NOTICE 

 10.1         The Operator
  shall call a meeting of the Management Committee to consider the Feasibility
  Report for a date no sooner than six months after the Feasibility Report was
  provided to each of the Parties. 

 10.2         The Management
  Committee shall consider each Feasibility Report prepared and may approve any
  Feasibility Report with such modifications, if any, as it considers necessary
  or desirable. Such approval by the Management Committee must be given by Participants
  holding aggregate Interests of not less than 75%. If the Feasibility Report
  is a Non-Operator's Feasibility Report the Operator is not entitled to vote
  with respect to the approval thereof. If a Feasibility Report is approved as
  aforesaid the Management Committee shall forthwith cause a Production Notice
  to be given to each of the Parties with an Interest by the Operator stating
  that the Management Committee intends to establish and bring a Mine into production
  pursuant to the Feasibility Report as so approved. 

 11.          
  ELECTION TO CONTRIBUTE 

 11.1         Each Party
  with an Interest may, within 120 days of receipt of the Production Notice, give
  the Operator notice committing to contribute its Proportionate Share of the
  Mine Costs. A Party which fails to give notice within the 120 day period shall
  be deemed to have elected not to contribute. 

 11.2         If any such
  Party fails to give such notice, that Party (a "non-Participant") shall forfeit
  the right to contribute to Mine Costs and shall suffer dilution and conversion
  of its Interest as provided in this paragraph. Those Parties which elected to
  contribute as aforesaid may thereupon elect to increase their contribution to
  the Mine Costs, if more than one Party then in 

 13 

 proportion to their respective Interests, by the amount which
  any Party has declined to contribute. If elections are made so that Mine Costs
  are fully committed the Interest of each Participant shall be increased and
  that of each non-Participant shall be decreased so that the Interest of each
  Party at all times is equal to: 

	(a)	the sum of its Exploration Costs, its Prior Exploration Costs
      and its contribution to Mine Costs;
	 	 
	 	                     divided
      by
	 	 
	(b)	the sum of the total Exploration Costs, total Prior Exploration
      Costs and the total Mine Costs of all the Parties;
	 	 
	 	                     multiplied
      by
	 	 
	(c)	100.

 If any Party's Interest is thereby less than 20% it shall
  forfeit its Interest to the Participants, if more than one then in proportion
  to their respective Interests, and that Party shall be entitled to receive as
  its sole remuneration and benefit in consideration of that assignment and conveyance,
  a 5% Net Profits Royalty calculated in accordance with Appendix II. Each Participant
  shall severally cause to be paid to each non-Participant any Net Profits Royalty
  derived from the Property in the manner provided in Appendix II. 

 11.3         If Mine Costs
  are not fully committed the Production Notice shall be deemed to be withdrawn.

 11.4         If Mine Costs
  are fully committed, the Operator shall diligently proceed to implement the
  Feasibility Report in accordance with normal standards in the mining industry.
  If the Operator fails to so implement the Feasibility Report within 12 months
  of the issuance of the Production Notice for reasons other than general economic
  conditions in the mining industry, any Party which forfeited the right to contribute
  to Mine Costs pursuant to section 11.2 shall have the right, exercisable during
  the 30 days following the expiration of such 12 month period, to reacquire from
  the Participants all of its Interest as last held, by paying its Proportionate
  Share of Mine Costs together with interest at the Prime Rate plus 2% to the
  Participants in proportion to their Interests. 

 11.5         During the
  12 month period referred to in section 11.4 the Participants shall not be obligated
  to provide any non-Participant with the results of any work carried out on the
  Property, the Participants' sole obligation during such period being to provide
  any non-Participant, on the written request of such non-Participant, but only
  once during the said 12 months, with a summary of the nature of the work carried
  out and the total Costs thereof. 

 12.           
  MINE FINANCING 

 12.1         The contributions
  of the Participants toward the Mine Costs shall be individually and separately
  provided by them. 

 14 

12.2         Any Party may
  pledge, mortgage, charge or otherwise encumber its Interest in order to secure
  monies borrowed and used by that Party for the sole purpose of enabling it to
  finance its participation under this Agreement or in order to secure by way
  of a general security interest as a part of the general corporate assets of
  that Party monies borrowed for its general corporate purposes, provided that
  the pledgee, mortgagee, holder of the charge or encumbrance (in this section
  called the "Chargee") shall hold such interest subject to the provisions of
  this Agreement and that if the Chargee realizes upon any of its security it
  will comply with this Agreement. The agreement between the Party, as borrower,
  and the Chargee shall contain specific provisions to the same effect as the
  provisions of this section. 

 13.         CONSTRUCTION

 13.1         Subject to
  Article 11, the Management Committee shall cause the Operator to, and the Operator
  shall, proceed with Construction with all reasonable dispatch after a Production
  Notice has been given. Construction shall be substantially in accordance with
  the Feasibility Report subject to any variations proposed in the Production
  Notice, and subject also to the right of the Management Committee to cause such
  other reasonable variations in Construction to be made as the Management Committee
  deems advisable. 

 14.          
  OPERATION OF THE MINE 

 14.1         Commencing
  with the Completion Date all Mining Operations shall be planned and conducted
  and all estimates, reports and statements shall be prepared and made on the
  basis of an Operating Year. 

 14.2         With the exception
  of the first Operating Year an operating plan for each Operating Year shall
  be submitted by the Operator to the Participants not later than the end of the
  third quarter in the year immediately preceding the Operating Year to which
  the Operating Plan relates. Each Operating Plan shall contain the following:

	(a)	a plan for the proposed Mining Operation;

	 	 
	(b)	a detailed estimate of all Mine Costs
        plus a reasonable allowance for contingencies;

	 	 
	(c)	an estimate of the quantity and quality
        of the ore to be mined and the concentrates or metals to be produced;
        and

	 	 
	(d)	such other facts as may be necessary
        to reasonably illustrate the results intended to be achieved by the Operating
        Plan,

 and upon request of any Participant the Operator shall meet
  with that Participant to discuss the Operating Plan and shall provide such additional
  or supplemental information as that Participant may reasonably require with
  respect thereto. 

 15 

 14.3         The Management
  Committee shall adopt each Operating Plan, with such changes as it deems necessary,
  at least three months before the commencement of the Operating Year to which
  the Operating Plan relates but the Management Committee may from time to time
  during the Operating Year amend any Operating Plan as required. 

 14.4         The Operator
  shall be entitled to include in the estimate of Mine Costs referred to in paragraph
  14.2(b) the reasonably estimated costs of satisfying continuing obligations
  that may remain after this Agreement terminates in excess of amounts actually
  expended. Such continuing obligations are or will be incurred as a result of
  the Joint Operation and shall include such things as monitoring, stabilization,
  reclamation or restoration obligations, severance and other employee benefit
  costs and all other obligations incurred or imposed as a result of the Joint
  Operation which continue or arise after termination of this Agreement and settlement
  of all accounts. The amount accrued from time to time for the satisfaction of
  such continuing obligations shall be classified as Costs hereunder but shall
  be segregated into a separate account. 

 15.           PAYMENT
  OF MINE COSTS 

 15.1         The Operator
  may invoice each Participant, from time to time, for that Participant's Proportionate
  Share of Mine Costs incurred to the date of the invoice, or at the beginning
  of each month for an advance equal to that Participant's Proportionate Share
  of the estimated cash disbursements to be made during the month. Each Participant
  shall pay its Proportionate Share of the Mine Costs or the estimated cash disbursements
  aforesaid to the Operator within 30 days after receipt of the invoice. If the
  payment or advance requested is not so made the amount of the payment or advance
  shall bear interest calculated monthly not in advance from the 30th day after
  the date of receipt of the invoice thereof by that Participant at a rate equivalent
  to the weighted average Prime Rate for the month plus 2% per annum until paid.
  The Operator shall have a lien on each Participant's Interest in order to secure
  that payment or advance together with interest which has accrued thereon. 

 15.2         If any Participant
  (in this section 15.2 called a "Defaulting Participant") fails to pay an invoice
  within the 30 day period as aforesaid, the Operator may, by notice, demand payment.
  If no payment is made within 30 days of the Operator's demand notice the Operator
  may, without limiting its other rights at law, enforce the lien created by section
  15.1 by taking possession of all or any part of the Defaulting Participant's
  Interest. The Operator may sell and dispose of the Interest which it has so
  taken into its possession by: 

	(a)	first offering that Interest to the
        non-Defaulting Participants, and if there is more than one then in proportion
        to the respective Interests of the Participants who wish to accept that
        offer, for that price which is the fair market value stated in the lower
        of two appraisals obtained by the Operator from independent, well recognized
        appraisers competent in the appraisal of mining properties; and

	 	 
	(b)	if the non-Defaulting Participants have
        not purchased all or part of that Interest as aforesaid, then by selling
        the balance, if any, either in whole or in part or in separate parcels
        at public auction or by private tender (neither the Participants nor the
        Defaulting Participant being entitled to bid) at a time and on whatever
        terms the Operator shall arrange, having first given notice to the Defaulting
        Participant of the time and place of the sale. 

 16 

As a condition of the sale as contemplated in subsection 15.2(b)
  the purchaser shall agree to be bound by this Agreement and, prior to acquiring
  the Interest, shall deliver notice to that effect to the parties in form acceptable
  to the Operator. The proceeds of the sale shall be applied by the Operator in
  payment of the amount due from the Defaulting Participant and interest as aforesaid,
  and the balance remaining, if any, shall be paid to the Defaulting Participant
  after deducting reasonable costs of the sale. Any sale or disposal made as aforesaid
  shall be a perpetual bar both at law and in equity by the Defaulting Participant
  and its successors and assigns against all other Participants and the Operator.

 16.           DISTRIBUTION
  IN KIND 

 16.1         It is expressly
  intended that, upon implementation of any Production Notice hereunder, the association
  of the parties shall be limited to the efficient production of Minerals from
  the Property and that each of the parties shall be entitled to use, dispose
  of or otherwise deal with its Proportionate Share of Minerals as it sees fit.
  Each Participant shall take in kind, f.o.b. truck or railcar on the Property
  and separately dispose of its Proportionate Share of the Minerals produced from
  the Mine. Extra costs and expenses incurred by reason of the Participants taking
  in kind and making separate dispositions shall be paid by each Participant directly
  and not through the Operator or Management Committee. 

 16.2         Each Participant
  shall construct, operate and maintain, all at its own cost and expense, any
  and all facilities which may be necessary to receive and store and dispose of
  its Proportionate Share of the Minerals at the rate they are produced. 

 16.3         If a Participant
  has not made the necessary arrangements to take in kind and store its share
  of production as aforesaid the Operator shall, at the sole cost and risk of
  that Participant store, in any location where it will not interfere with Mining
  Operations, the production owned by that Participant. The Operator and the other
  parties shall be under no responsibility with respect thereto. All of the Costs
  involved in arranging and providing storage shall be billed directly to, and
  be the sole responsibility of, the Participant whose share of production is
  so stored. The Operator's charges for such assistance and any other related
  matters shall be billed directly to an be the sole responsibility of the Participant.
  All such billings shall be subject mutatis mutandis to the provisions
  of sections 15.1 and 15.2 thereof.

        on its then Interest, of all obligations and liabilities which arose at
        any time prior to the date of surrender;

	 	 	 
	(ii) 	 	if the Operator has not included in
        Mine Costs the costs of continuing obligations as set out in section 14.4
        hereof, pay its reasonably estimated Proportionate Share, based on the
        surrendering Party's then Interest, of the Costs of rehabilitating the
        Mine site and of reclamation as at the date of surrender; and

	 	 	 
	(iii)	 	 hold in confidence, for a period of
        two years from the date of surrender, all information and data which it
        acquired pursuant to this Agreement.

 17.2         Upon the surrender
  of its entire Interest as contemplated in section 17.1 and upon delivery of
  a release in writing in form acceptable to counsel for the Operator releasing
  the other parties from all claims and demand hereunder, the surrendering party
  shall be relieved of all obligations or liabilities hereunder except for those
  which arose or accrued or were accruing due on or before the date of the surrender.

 17.3         A Party to
  whom a notice of surrender has been given may elect, by notice within 90 days
  to the Party which first gave the notice, to accept the surrender, in which
  case the provisions of this Article shall apply, or to join in the surrender.
  If all of the Parties join in the surrender the Joint Operation shall be terminated

  of Mining Operations. The Operator's recommendation shall include a plan and
  budget (in this Article called the "Mining Maintenance Plan") in reasonable
  detail of the activities to be performed to maintain the Assets and Property
  during the period of suspension and the Costs to be incurred. The Management
  Committee may at any time subsequent to the Completion Date, cause the Operator
  to suspend Mining Operations in accordance with the Operator's recommendation
  with such changes to the Mine Maintenance Plan as the Management Committee deems
  necessary. The Participants shall be committed to contribute their Proportionate
  Share of the Costs incurred in connection with the Mine Maintenance Plan. The

 18.2         The Operator
  may at any time following a period of at least 90 days during which Mining Operations
  have been suspended, upon at least 30 days notice to all Participants, or in
  the events described in section 18.1, recommend that the Management Committee
  approve the permanent termination of Mining Operations. The Operator's recommendation
  shall include a plan and budget (in this Article called the "Mine Closure Plan")
  in reasonable detail of the activities 

 18 

 to be performed to close the Mine and reclaim the Property.
  The Management Committee may, by unanimous approval of the representatives of
  all Participants, approve the Operator's recommendation with such changes to
  the Mine Closure Plan as the Management Committee deems necessary. 

 18.3         If the Management
  Committee approves the Operator's recommendation to permanently terminate Mining
  Operations it shall cause the Operator to: 

  	(a)
   	implement the Mine Closure Plan whereupon
          the Participants shall be committed to pay, in proportion to their respective
          Interests, such Costs as may be required to implement that Mine Closure
          Plan;

          as may reasonably be removed and disposed of profitably and such other
          Assets as the Operator may be required to remove pursuant to applicable
          environmental and mining laws; and

	 	 
	(c)	sell, abandon or otherwise dispose
          of the Property.

 The disposal price for the Assets and the Property shall be
  the best price obtainable and the net revenues, if any, from the removal and
  sale shall be credited to the Participants in proportion to their respective
  Interests. 

 18.4         If the Management
  Committee does not approve the Operator's recommendation contemplated to permanently
  terminate Mining Operations the Operator shall maintain Mining Operations in
  accordance with the Mine Maintenance Plan.

  Committee, or giving 60 days notice of its intention to do so to the other Parties
  with an Interest. In this latter event the Parties, other than the Operator,
  shall be entitled to receive from the Operator, on request prior to the date
  of the surrender or lapse, a conveyance of that portion of the Property intended
  for surrender or lapse, together with copies of any plans, assay maps, diamond
  drill records and factual engineering data in the Operator's possession and

 28.9         If the Other
  Parties do accept the Offer within the period provided for in section 28.6 but
  fail to close the transaction contemplated thereby within 90 days following
  receipt of such Offer, the Transferring Party may complete a sale and purchase
  of its Interest or a portion thereof on any terms and conditions but in any
  event such sale and purchase shall be completed within nine months from the
  expiration of the right of the Other Parties to accept such Offer or the Transferring
  Party must again comply with the provisions of this article. 

 28.10       While any Offer is outstanding
  no other Offer may be made until the first mentioned Offer is disposed of and
  any sale resulting therefrom completed or abandoned in accordance with the provisions

  NET PROFITS ROYALTY

  "Owner") shall be entitled to a 100% beneficial interest in the Property subject
  to the Net Profits Royalty. The Net Profits Royalty shall be calculated as follows:

  the Royalty Account. While there is any debit balance in the Royalty Account,
  the Owner shall retain all Product or Net Profits (in proportion to their Interests
  if more than one Owner). Whenever the Royalty Account shows no debits, Net Profits
  in an amount equal to the credit balance in the Royalty Account shall be distributed
  to the Royalty Holder in an amount equal to the applicable Net Profits Royalty,
  and the balance to the Owner. 

 3.          The Operator
  shall debit or credit amounts to the Royalty Account, whichever is applicable,
  on a monthly basis and distribution of Net Profits shall be made on an interim
  basis within 20 days of the end of each month. A final settlement of the distribution
  of Net Profits shall be made within 90 days of the end of each calendar year.
  The Owner shall be entitled to deduct any overpayment of Net Profits as revealed
  in the annual calculation for purposes of the final settlement from future payments
  due to the Royalty Holder. Any underpayment shall be paid by the Owner to the
  Royalty Holder forthwith. 

 4.          The Owner
  shall at all times maintain adequate records which shall be made available to
  the Royalty Holder in order that the Royalty Holder may verify the correctness
  of any entries in the Royalty Account or in the determination of Net Profits.
  The Owner shall utilize methods of weighing and sampling ore which are generally
  accepted within the industry. 

 5.          The terms
  which are defined in the Agreement shall have the same defined meanings in this
