               force before or after the date hereof, provided that:

               fees and court costs, from amounts otherwise due to EWR and CRC hereunder;

               payments and incur all expenditures required to keep the Property in good
               standing; and

               amount of such deficiency within 15 days following receipt of notice of such

|(d) |  | deliver to the Owners an acknowledgement of abandonment and release of any

               opportunity sometimes applied to persons occupying a relationship similar
               to that of the Participants shall not apply with respect to participation by any
               Participant in any business activity or endeavour outside the Joint Venture,
               and, without implied limitation, a Participant shall not be accountable to the
               others for participation in any such business activity or endeavour outside the

               any Mineral Products or any other Participants share of production in any

Article 5

INTERESTS OF
PARTICIPANTS

Interests

5.1 On the Participation Date
contemplated in §3.10(a), Teck Cominco shall have an undivided 51% Interest, EWR
shall have an undivided 24.5% Interest and CRC shall have an undivided 24.5% Interest. On
the Participation Date contemplated in §3.10(c), Teck Cominco shall have an undivided
60% Interest, EWR shall have an undivided 20% Interest and CRC shall have an undivided 20%
Interest. Thereafter, each Participant shall have such Interest as is determined from time
to time in accordance with the provisions of this Agreement.

Dilution Formula

5.2 Subsequent to the Participation
Date, the respective Interests of the Participants shall be determined from time to time
as being equal to the product obtained by multiplying 100% by a fraction of which the
numerator is as follows:

(a)    
          If the Participation Date was established under 3.10(a):

`Teck Cominco:         $775,000, being its Expenditures underss.3.2(a)
                  EWR                   24.5/51 of $775,000
                  CRC:                  24.5/51 of $775,000`

(b)    
          If the Participation Date was established under 3.10(c):

`Teck Cominco:         $2,275,000, being its Expenditures under 3.2(a) and 3.2(b)
                  EWR:                  20/60 of $2,275,000
                  CRC:                  20/60 of $2,275,000`

| | plus,
in each case, above that Participants respective contribution to Expenditures and
Production Program Costs made subsequent to the Participation Date;
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------

and the denominator is $775,000, if
the Participation Date is established under §3.10(a), or $2,275,000, if the
Participation Date was established under §3.10(c), plus in each case, the amount of
all contributions to Expenditures and Production Program Costs made subsequent to the
Participation Date by all Participants.

Multiple Participants

5.3 If there are more than two
Participants the dilution formula in §5.2 shall be applied mutatis mutandis as
required provided, that an assignment by a Participant of all or part of its Interest
shall carry with it an assignment of that proportion of the aggregate of the
Participants Expenditures and Production Program Costs to the time of assignment
which equals the percentage of the Participants Interest which is being assigned.

Dilution and Conversion of an
Interest to a Royalty 5.4 The respective Interests of the Participants shall not change so
long as they each contribute their respective Cost Share of every Program as set out in
Article 8 and Production Program as set out in Article 9. At any time and from time to
time after a Participant elects or is deemed to have elected not to contribute to a
Program or Production Program, its respective Interest shall be reduced, and each other
Participants Interest shall be proportionately increased, in accordance with the
formula set out in §5.2. If, as a result of such calculation, the Interest of a
Participant is reduced to or below 15%, its Interest shall be deemed to be converted to a
Net Profits Royalty and thereafter such party shall have no further rights or interest in
respect of the Assets or under this Agreement, save and except for the Net Profits
Royalty, provided however, that if a Participant assigns part of its Interest the
percentage Interest to which the Participants and the assignees Interest must
be diluted prior to its Interest being converted to a Net Profits Royalty shall remain at
15% for each of them and the Net Profits Royalty to which the assigning Participants
or the assignees Interest shall be converted shall be that derived by multiplying
the Net Profits Royalty to which the assigning Participants Interest would have been
converted to prior to the assignment by the fraction, the numerator of which is the
Participants Interest immediately after the assignment and the denominator of which
is the assigning Participants Interest immediately prior to the assignment and such
shall be applied in like fashion for any additional assignments.

Royalty Calculation and
Payment

5.5 Any Net Profits Royalty shall be
calculated pursuant to Schedule 2 by the Operator if it is the sole Participant, or if
there is more than one Participant, by each Participant as to its respective share of the
Net Profits Royalty and the Operator or the Participants, as the case may be, shall pay
the Net Profits Royalty as described in Schedule 2.

Article 6

MANAGEMENT COMMITTEE

Management Committee

6.1 The Participants shall, as soon
as is practicable after the Participation Date, establish a Management Committee which
shall direct and control the operations of the Joint Venture.

Members

6.2 Each Participant having an
Interest shall be entitled to two members on the Management Committee. A Participant may
from time to time revoke in writing the appointment of any of its nominees on the
Management Committee and appoint in writing another in his place. A Participant may from
time to time in writing appoint one alternate member for any member theretofore appointed
by such Participant. Alternate members may attend meetings of the Management Committee
and, in the absence of the member, his alternate may vote and otherwise act in the place
and stead of a member. Whenever any member or alternate member votes or acts, his votes or
actions shall for all purposes of this Agreement be considered the actions of the
Participant whom he represents. The Participants shall give written notice to each other
from time to time as to names, addresses, telephone numbers and facsimile numbers of their
respective members and alternates on the Management Committee.

Time and Place of Meetings

6.3 All meetings of the Management
Committee shall be held in Vancouver, B.C. unless all members of the Management Committee
agree otherwise and any member of the Management Committee may call a meeting at any time
by giving seven days notice to the other members of the time and place of such
meeting and the general nature of the business to be conducted, but no Participant other
than the Operator shall be entitled to call a meeting less than three months after the
date of the last meeting of the Management Committee. Any member of the Management
Committee, or his alternate, may waive in writing the giving of such notice before or
after such meeting. Otherwise, the giving of notices under this Article shall be governed
by Article 18.

Resolutions in Writing

6.4 Any resolution in writing signed
by all members of the Management Committee in one or more counterparts shall be as valid
and binding as if passed at a meeting of the Management Committee duly called and
constituted. The Chairman of a meeting of the Management Committee may require that a
resolution duly passed at such meeting be reduced to writing and signed by all of the
Participants present at such meeting in order to properly record such resolution.

Quorum

6.5 Except as herein set out, a
quorum for any meeting of the Management Committee shall consist of a member or members
representing a Participant or Participants whose Interest or Interests aggregate in excess
of 50%. If a quorum is not present within 30 minutes after the time fixed for holding any
such meeting, the meeting shall be adjourned to the sixth Business Day thereafter at the
same time and place. Notice of any adjournment shall be given forthwith to each member of
the Management Committee who was not present at the adjourned meeting. At the meeting to
which the prior meeting was adjourned, the members (or their respective alternates)
present in person shall form a quorum and may transact the business for which the meeting
was originally convened.

Voting

6.6 Except as herein set out, the
members of the Management Committee or their respective alternates shall have a number of
votes equal in number to the Interest held by the Participant that he or they represent.
The Management Committee shall decide all matters coming before it at a meeting by the
affirmative vote of a majority of the votes entitled to be cast by members at the meeting.
The representative of the Operator shall act as Chairman of each meeting of the Management
Committee and, as such, shall have an additional or casting vote in the case of an
equality of votes on any matter.

Secretary and Records

6.7 The Management Committee shall
appoint a secretary (who need not be a member of the Management Committee) who shall keep
a record of the meetings of the Management Committee, and circulate to all members minutes
of each meeting promptly after the conclusion thereof. Each Participant shall have the
right to examine and take extracts of all records of the Management Committee (which shall
be maintained by the Operator), at reasonable times and on reasonable notice at the
Operators offices during regular business hours.

Abandonment of Property

6.8 The Management Committee may
decide to surrender or abandon a portion of the Property, provided such decision is made
at least 90 days prior to the date on which such portion shall cease to be in good
standing in the records of the appropriate governmental authority, and provided further
that notice of such proposed abandonment is forthwith given to any Participant which was
not represented at the meeting at which such decision was made. Those Participants which
did not vote in favour of the abandonment may elect, by notice to the Operator within 30
days following the meeting or such notification, as the case may be, that the portion to
be abandoned be transferred to it, or if more than one, to them in proportion to their
respective Interests, whereupon the Operator and those Participants that voted in favour
of the abandonment shall, forthwith after the expiry of the applicable 30-day period,
transfer, assign and quit claim the subject portion to the Participant or Participants so
electing. Failing any such election, the subject portion may be abandoned or surrendered
as decided upon. Following a transfer or abandonment under this paragraph, the portion so
transferred or abandoned shall thereafter cease to form part of the Property and shall no
longer be subject to this Agreement, save and except with respect to such obligations or
liabilities of the Participants as have accrued hereunder up to the date of such transfer
or abandonment.

               end of each Operating Year;
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(g) |  | to permit the Participants, at their own expense, to inspect, take abstracts

               not perform such work in a manner that is consistent with good exploration,

|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Non-Performance by the
Operator

7.4 If the Operator fails to perform
in a manner that is consistent with good exploration, engineering and mining practices or
fails to perform in a manner consistent with its duties and responsibilities under this
Agreement, or is adjudged to be bankrupt or insolvent or a receiver is appointed for its
business and assets, then the Management Committee shall give to the Operator written
notice setting forth particulars of the Operators default. The Operator shall within
30 days of receipt of such notice commence to remedy the default. Failure of the Operator
to commence to remedy the default within such 30-day period (and thereafter to proceed
continuously and diligently to complete all required remedial action) shall be grounds for
termination of the Operators appointment; provided that if there shall be any
disagreement between the Management Committee and the Operator as to whether a default has
occurred, the matter may be submitted to arbitration under Article 17, and the Operator
shall not be considered in default of any obligation determined on the arbitration if it
commences to remedy the default within 10 days after the arbitration decision or within
such longer period as may be fixed in the arbitration award. On any termination of the
Operators appointment hereunder, a meeting of the Management Committee shall
forthwith be convened to appoint another party who consents to act as Operator, and
determine its terms of engagement. At such meeting, an Operator in default hereunder shall
not be entitled to vote as a Participant for the purposes of this paragraph and the
remaining Participant or Participants shall be sufficient to form a quorum for such
purposes.

Delivery of Assets by
Former Operator to Successor Operator

7.5 Upon ceasing to be Operator, the
former Operator shall forthwith deliver to the successor Operator custody of all Assets
and any books and records pertaining to the Assets which it prepared or maintained in its
capacity as Operator. The successor Operator shall assume all of the rights,
responsibilities, duties, and status of the previous Operator as provided in this
Agreement. The successor Operator shall have no obligation to hire any of the employees of
the former Operator.

Termination of Joint
Venture if No Operator

7.6 If the Operator resigns or is
removed and no other party consents to act as Operator, the Joint Venture shall be
terminated and the Assets shall be liquidated or sold and the Assets or proceeds from the
sale thereof distributed to the Participants, net of liabilities hereunder or related
thereto, in accordance with their Interests. Each Participant shall be responsible for its
Cost Share of all costs and expenses related to such termination and liquidation. The
party which was the Operator may, if it consents to act, continue to act as Operator to
effect such termination and liquidation and it shall have a lien on the Participants
respective interests in the Assets and any proceeds therefrom as security for their
respective Cost Shares of all costs, expenses and other liabilities owing in respect of or
as of the date of such termination.

Indemnification of
Operator

7.7 Subject to §7.8, each
Participant shall, pro rata to its Interest, indemnify and save the Operator and any
former Operator harmless from and against any loss, liability, claim, demand, damage,
expense, injury and death (including, without limiting the generality of the foregoing,
legal fees) resulting from any acts or omissions of the Operator or its officers,
employees or agents.

No Indemnification of
Operator

7.8 Notwithstanding §7.7, the
Operator shall not be indemnified nor held harmless by any of the Participants for any
loss, liability, claim, demand, damage, expense, injury or death (including, without
limiting the generality of the foregoing, legal fees) resulting from the gross negligence
or wilful misconduct of the Operator or its officers, employees or agents; provided
however that in no case shall indemnification be withheld if the act or omission of the
Operator or its officers, employees or agents was done or omitted to be done: (a) at the
direction, or within the scope of the direction, of the unanimous consent of the
Management

Committee;

(b)    
          with the concurrence of the unanimous consent of the Management Committee; or
          (c) unilaterally and in good faith by the Operator to protect life, limb or
          property.

Indemnification in
Proportion to Interests

7.9 The obligation of a Participant
to indemnify and save the Operator harmless pursuant to §7.7 shall be in proportion
to its Interest as at the date that the loss, liability, claim, demand, damage, expense,
injury or death occurred or arose.

No Liability for Special
Damages

7.10 The Operator shall not be liable
to any Participant nor shall any Participant be liable to the Operator in contract, tort
or otherwise for special or consequential damages, including, without limiting the
generality of the foregoing, loss of profits or revenues.

Emergency Expenditures

7.11 Notwithstanding anything herein
contained to the contrary, the Operator shall be entitled to incur, and the Participants
shall be responsible for their respective Cost Share of, any costs expended which the
Operator deems necessary to preserve or protect life, limb, property or the environment in
respect of the Property and the operations hereunder.

Article 8

PROGRAMS

Expenditures to be
Incurred Under Programs

8.1 After the Participation Date, but
subject to §8.2, Expenditures shall only be incurred under and pursuant to Programs
prepared by the Operator and approved by the Management Committee as provided in this
Article. Any Preliminary Feasibility Report or Feasibility Report shall be prepared
pursuant to a separate Program.

Programs in Progress on
Participation Date

8.2 Upon the occurrence of the
Participation Date, Expenditures incurred by Teck Cominco or the Operator as part of
ongoing exploration work then in progress, up to a maximum of $100,000, shall be deemed to
have been approved as a Program and each Participant shall be liable for its Cost Share
thereof, upon being invoiced by Teck Cominco or Operator, as the case may be. Thereafter,
the Operator shall, within 120 days following completion of each Program, prepare and
submit to the Management Committee a Program of not less than 6 months and a maximum of 12
months in duration, which shall include at least such Expenditures as are necessary to
maintain the Property in good standing. A Program for the preparation of a Feasibility
Report and a Production Program may be for such duration as the Operator estimates is
required for the completion thereof.

Election to Participate
in Programs

8.3 Within 30 days after the approval
by the Management Committee of a Program, the Participants shall each give written notice
to the Operator stating whether or not they elect to contribute their respective Cost
Shares of such Program. Failure by a Participant to give notice pursuant to this paragraph
within such 30-day period shall be deemed to be an election by that Participant not to
contribute to such Program.

Effect of Election to Not
Contribute

8.4 If a Participant (for the
purposes hereof a Non-Contributor) elects or is deemed to have elected not to
contribute its Cost Share of a Program, each other Participant (for the purposes hereof a
Contributor) that has elected to contribute its Cost Share of the Program may
give notice in writing to the Operator stating that it shall contribute, in addition to
its own Cost Share, the Cost Share of the Non-Contributor. If more than one Participant
gives such notice, they shall contribute pro rata to their Interests or as they may
otherwise agree. In such event, subject to §8.5, the Operator shall proceed with such
Program and, on completion of such Program, the Interests of the parties shall be adjusted
in accordance with §5.4; provided that, if such Program is completed to the extent of
less than 80% of the originally estimated Expenditures thereunder, the Interests of the
parties shall not be adjusted unless notice is first given to the Non-Contributor that the
Program was abated, together with notice of the amount of the actual Expenditures
thereunder, and the Non-Contributor does not, within 20 days thereafter, reimburse the
Contributor or Contributors to the extent of its Cost Share thereof (being the amount
which the respective Contributor elected to and did contribute instead of the
Non-Contributor), together with interest thereon from the date contributed by the
Contributor, at a per annum rate equal to the Prime Rate plus 2%. If the Non-Contributor
so reimburses the Contributor or Contributors within such 20-day period, it shall be
deemed to have elected to contribute its Cost Share of such Program and the Interests of
the parties shall not be adjusted. A Participant that elects or is deemed to have elected
not to contribute to a Program may, subject to §5.4, participate in future Programs.

Operator Not to Proceed
Unless Program is Fully Funded

8.5 The Operator shall not proceed
with any Program which is not fully subscribed except that the Operator shall at all times
be entitled to incur such Expenditures as are necessary pursuant to §7.11, pursuant
to a Property Holding Program or to maintain the Property in good standing and the
Participants shall be liable for their Cost Share thereof, regardless of any election
hereunder. If the Participants fully subscribe to a Program, the Operator shall proceed
with such Program.

Obligation to Pay
Expenditures and Overruns

8.6 An election by a Participant to
contribute to a Program shall make that Participant liable to pay its respective share of
Expenditures actually incurred under or pursuant to the Program including Program
Overruns, as hereinafter defined, of up to but not exceeding 20%.

Procedures for Payment

8.7 After having elected to
contribute to a Program which is proceeded with or if a Participant is otherwise obligated
to pay its Cost Share, a Participant shall, within 15 days after being requested in
writing to do so by the Operator, pay such portion of its Cost Share as the Operator may
require, including cash calls for anticipated Expenditures, but the Operator shall not
require payment of any funds more than 45 days in advance of the anticipated date of
disbursement thereof.

Meeting Required to
Approve Excess Program Overruns

8.8 If it appears to the Operator
that Expenditures shall exceed those estimated under a Program, the Operator shall
immediately give written notice to the Participants contributing to that Program outlining
the nature and extent of the additional costs and expenses (herein called Program
Overruns) and the reasons therefor. If Program Overruns are estimated to exceed by
20% those approved under the Program (herein called Excess Program Overruns),
the notice of the Operator shall contain a notice of a meeting of the Management
Committee, to be held no sooner than five Business Days after the date of delivery of the
notice, for the purpose of considering, and if deemed advisable, approving the Excess
Program Overruns. If the Excess Program Overruns are approved by the Management Committee,
the Participants contributing to that Program shall, within 15 days after the receipt of a
written request from the Operator, provide the Operator with their Cost Share of such
Excess Program Overruns. If such Excess Program Overruns are not approved by the
Management Committee, the Operator shall curtail or abandon such Program.

Effect of Default in
Paying Expenditures

8.9 If a Participant at any time
fails to pay its Cost Share in accordance with §8.5, §8.7 or §8.8, the
Operator may give written notice to that Participant demanding payment and, if that
Participant has not paid such amount, together with interest thereon at Prime Rate plus 2%
from the date on which payment was due, within 15 days after receipt of such notice, the
Interest of that Participant shall be deemed to be converted to a Net Profits Royalty and
thereafter that party shall have no further rights or interest in respect of the Assets or
under this Agreement, save and except its Net Profits Royalty. Notwithstanding the
conversion of a defaulting partys Interest pursuant to this paragraph, the Operator
shall be entitled to take action to recover the amount owing by such defaulting party, and
such conversion shall otherwise not relieve the defaulting party of any liability or
obligation incurred up to the time of such default and conversion. The Operator shall have
a lien on the Net Profits Royalty of the defaulting party to recover any amounts so owing,
together with interest thereon, and may deduct same from any payments due in respect of
the defaulting partys Net Profits Royalty until so recovered in full. Any interest
paid by or recovered from the defaulting Participant shall be for the account of the
Participants that provided funds required of them as a result of the default, pro rata to
their contributions, or otherwise shall be paid to the Participants not in default, pro
rata to their Interests.

Program for a Preliminary
Feasibility Report

8.10 Any of the Participants holding
in the aggregate not less than a 40% Interest, shall be entitled to request, by written
notice to the Operator, that the Operator propose a Program for the preparation of a
Preliminary Feasibility Report.

Program for a Feasibility
Report

8.11 Any of the Participants holding
in the aggregate not less than a 40% Interest, shall be entitled to request, by written
notice to the Operator, that the Operator propose a Program for the preparation of a
Feasibility Report. If the Operator fails to do so within 60 days following receipt of
such notice, the Participants giving such notice shall be entitled to prepare, at their
own expense, a Feasibility Report and, forthwith upon completion of same, shall deliver
copies thereof to the Operator and the other Participants. The preparation of a
Feasibility Report by a Participant or Participants under this paragraph shall not affect
the rights of the Operator to continue to propose and carry out Programs as otherwise set
forth in this Article.

Participants
Feasibility Report

8.12 In the event that a Feasibility
Report prepared by one or more Participants does not demonstrate that the Property or a
part thereof may be economically placed into Commercial Production, no further action
shall be taken in respect thereof and any expenses incurred by the Participants which
prepared such Feasibility Report shall be for their own account and shall not be
considered Expenditures made under this Agreement.

Favourable Feasibility
Report

8.13 In the event that a Feasibility
Report prepared by the Operator as a Program or by one or more Participants pursuant to
§8.11 demonstrates that the Property or a part thereof may be economically placed
into Commercial Production, the Feasibility Report shall be delivered to the Participants
or other Participants, as the case may be, and the provisions of Article 9 shall apply.

Provision of Security

8.14 To the extent that security
(whether in the form of cash, negotiable securities, letters of guarantee, irrevocable
letters of credit or otherwise) is required to be posted with or in favour of any
regulatory authority or government in connection with Programs, a Production Program or
Operating Plan, each of the Participants shall lodge security, in such form as may be
acceptable to the particular authority, in an amount proportionate to its Interest at the
time and to the total amount of security then required by the authority; and if the
security shall expire at a particular time a Participant shall replace or renew its
security before that time if required by the authority.

Article 9

PRODUCTION PROGRAM

Delivery of Proposed
Production Program

9.1 At any time after delivery to the
Participants of a Feasibility Report pursuant to §8.13, the Operator may, and shall
within 120 days of receipt by it from Participants holding in the aggregate not less than
a 40% Interest of a request in writing to do so, prepare and deliver to the Participants a
Production Program which shall be based on such Feasibility Report. The preparation of the
Production Program shall be deemed to be pursuant to a Program in which each Participant
has elected to pay its Cost Share of Expenditures incurred thereunder. Within 180 days of
the receipt by each Participant from the Operator of a Production Program, each such
Participant shall give written notice to the Operator stating whether it elects to
contribute its Cost Share of the Production Program (subject to §5.2(b)). Failure to
give such notice within such 180-day period shall be deemed to be an election by such
Participant not to contribute to the Production Program.

Operator to Proceed with
Adopted Production Program

9.2 If Participants holding Interests
aggregating not less than 51% elect to contribute their respective Cost Share of a
Production Program, together with the Cost Share of those Participants who have elected or
are deemed to have elected not to participate in the Production Program, the Operator
shall, subject to §9.3, proceed with such Production Program and the provisions of
§5.4 shall apply. If the Feasibility Report on which such Production Program is based
was prepared by one or more Participants pursuant to §8.11, then 125% of the costs
thereof as incurred by such Participants and as supported by written evidence shall be
deemed to be Expenditures and, within 15 days following a written demand therefor
(together with such evidence), the other Participants shall reimburse the Participant or
Participants that prepared such Feasibility Report to the extent of their respective Cost
Shares thereof. Failure by a Participant to reimburse its Cost Share thereof shall result
in dilution of its Interest under §5.4, with the non-reimbursed portion as aforesaid
deemed to have been contributed (in addition to its own Cost Share) by the Participant
that prepared the Feasibility Report, or, if more than one Participant, such shall be
apportioned among them in accordance with their respective contributions to the Costs of
preparing the Feasibility Report.

Obligation to Pay
Production Program Costs and Overruns

9.3 An election to contribute to a
Production Program shall make a Participant liable to pay its Cost Share of all of the
Production Program Costs actually incurred under or pursuant to such Production Program,
including Production Program Overruns (as hereinafter defined) up to but not exceeding
15%. The Operator need not proceed with a Production Program until each Participant has
delivered proof, satisfactory to the Operator, of the Participants ability to pay
its Cost Share of such Production Program including, if required by the Operator from any
Participant whose net worth (according to its last available balance sheet) is less than
300% of its Cost Share of anticipated Production Program Costs, Letters of Credit or other
reasonable guarantee of availability of funds.

Procedures for Payment

9.4 After having elected to
contribute to a Production Program which is proceeded with, each Participant shall, within
15 days after being requested in writing to do so by the Operator, pay such portion of its
Cost Share of the Production Program Costs as the Operator may require, including cash
calls for anticipated Production Program Costs, and provide such security or additional
security as may then be required under §8.14, but the Operator shall not require
payment of any funds more than 45 days in advance of the proposed expenditure thereof.

Meeting Required to
Approve Excess Production Program Cost Overruns

9.5 If it appears to the Operator
that Production Program Costs shall exceed those estimated under the Production Program,
the Operator shall immediately give written notice to the Participants outlining the
nature and extent of the additional costs and expenses (herein called Production
Program Overruns) and the reasons therefor. If Production Program Overruns are
estimated to exceed by 15% those estimated under the Production Program (herein called
Excess Production Program Overruns), the notice of the Operator shall contain
a notice of a meeting of the Management Committee, to be held no sooner than five Business
Days after the date of delivery of the notice, for the purpose of considering, and if
deemed advisable, approving the Excess Production Program Overruns. If the Excess
Production Program Overruns are approved by the Management Committee, each Participant
shall, within 15 days after the receipt of a written request from the Operator, provide
the Operator with its Cost Share of such Excess Production Program Overruns.

Curtailment of Production
Program

9.6 If Excess Production Program
Overruns are not approved by the Management Committee, as provided in §9.5, the
Operator shall have the right to curtail or abandon the Production Program. Alternatively,
any Participant that has approved such Excess Production Program Overruns may advance the
amount of such Excess Production Program Overruns which have not been accepted (if more
than one of them, pro rata to their respective Interests or as they may otherwise agree)
and, on so doing, such Participants shall be entitled to recover the amount of such
advances from the sale of Mineral Products of the other Participant or Participants,
together with interest thereon from the date advanced at a per annum rate equal to the
Prime Rate plus 4%, and the provisions of §11.3 shall apply with respect thereto.

Effect of Default in
Paying Production Program Costs

9.7 If a Participant at any time
fails to pay its Cost Share of Production Program Costs (including Production Program
Overruns and approved Excess Production Program Overruns) in accordance with §9.4 or
§9.5, the Operator may give written notice to such Participant demanding payment and,
if such Participant has not paid such amount, together with interest thereon at Prime Rate
plus 2% from the date on which payment was due, within 15 days after receipt of such
notice, such Participant shall be deemed to be in default hereunder and either, as the
Management Committee (excluding the Participant in default) may determine, (a) its
Interest shall be deemed converted to a Net Profits Royalty, or (b) it shall be liable for
all damages occasioned to the other Participants by its default hereunder, unaffected by
any dilution in its Interest arising from failure or delay in making contributions. If the
Management Committee adopts alternative (a), thereafter, such defaulting Participant shall
have no further rights or interest in respect of the Assets or under this Agreement, save
and except for such Net Profits Royalty. For the purposes of the calculation of Net
Profits under Schedule 2, it is understood that cumulative Costs thereunder shall include,
inter alia, all Expenditures and Production Program Costs whether or not a portion of such
costs were contributed by the holder of the Net Profits Royalty. Any interest paid by or
recovered from the defaulting Participant shall be for the account of the Participants
that provided funds required of them as a result of the default pro rata to their
contributions, or otherwise shall be paid to the Participants not in default, pro rata to
their Interests.

Operators Right to
Curtail Production Program Upon Default

9.8 If, upon the default of a
Participant pursuant to §9.7, the other Participant or Participants, if more than
one, do not thereafter elect to contribute pro rata to their Interests or as otherwise
agreed by them, what would have been the defaulting Participants Cost Share of
remaining Production Program Costs, the Operator shall have the right to curtail or
abandon the Production Program.

Article 10

OPERATING PLANS

Obligation to Pay
Operating Costs and Overruns

10.1 Following the Completion Date,
each Participant shall be liable to pay its Cost Share of all Operating Costs incurred
under Operating Plans, including Operating Cost Overruns (as hereinafter defined) up to
but not exceeding 20%.

Operating Plans

10.2 At least 90 days prior to the
date the Operator anticipates the Completion Date shall occur, the Operator shall propose
and deliver to the Participants an Operating Plan for the first Operating Year.
Subsequently, at least 90 days before the commencement of each succeeding Operating Year,
the Operator shall propose an Operating Plan by delivery of such to each Participant, for
such succeeding Operating Year. Within 30 days of delivery of a proposed Operating Plan
hereunder, a meeting of the Management Committee shall be convened to review, amend (if
deemed appropriate) and approve same.

Excess Operating Cost
Overruns

10.3 Except as herein provided, the
Operator shall have the power and authority to deviate from or make modifications to
Operating Plans from time to time, in accordance with good engineering and mining
practices. If it appears to the Operator that Operating Costs shall exceed those estimated
under an Operating Plan, the Operator shall immediately give written notice to the
Participants outlining the nature and extent of the additional costs and expenses (herein
called Operating Cost Overruns) and the reasons therefor. If Operating Cost
Overruns are estimated to exceed by 20% those estimated under the Operating Plan (herein
called Excess Operating Cost Overruns), the notice of the Operator shall
contain a notice of a meeting of the Management Committee, to be held no sooner than five
Business Days after the date of delivery of the notice, together with a proposed amendment
to the Operating Plan. The meeting of the Management Committee shall be convened to
review, amend (if deemed appropriate) and approve same.

No Agreement on Operating
Plans

10.4 In the event that a proposed
Operating Plan or amendment thereto is not approved by the Management Committee as
hereinbefore provided, the Operating Plan shall be deemed to be approved as submitted and
shall be implemented by the Operator provided that it is consistent with:

(a)    
          the Feasibility Report; or (b) the most recently approved Operating Plan.

If the Management Committee does not
approve an Operating Plan for 3 successive Operating Years, the Operator shall prepare a
shut-down plan for the mine and budget therefor which shall be implemented within 90 days
after it is submitted to each Participant. Each Participant shall pay or to the
satisfaction of the Operator provide security for, its entire Cost Share of the shut-down
budget.

For the purposes of this paragraph,
an Operating Plan shall be consistent with the Feasibility Report or prior Operating Plan
if the proposed production rate has not changed by more than 20% and projected Operating
Costs have not changed by more than 20% from those depicted in the later of the
Feasibility Report or prior Operating Plan and if the capital costs included in the
proposed Operating Plan are generally consistent with those provided in the Feasibility
Report for post-commencement of Commercial Production or in the prior Operating Plan.

Statements of Operating
Costs

10.5 Following the Completion Date,
the Operator shall, on or before the 15th day of each month, submit to the Participants a
statement of Operating Costs, which the Operator estimates shall be incurred to the end of
the next month (taking into account any current cash shortfall or surplus), and Operating
Costs at the time incurred and unpaid), and on or before the last day of the month in
which such statement is submitted, each Participant shall pay to the Operator its
respective Cost Share thereof.

Effect of Default in
Paying Operating Costs

10.6 If a Participant (for the
purposes hereof a Defaulting Participant) fails to pay all or any part of its
Cost Share pursuant to §10.5, the other Participant or Participants if more than one,
shall be entitled, pro rata to their Interests or as otherwise agreed by them, to pay all
or a portion of the unpaid Cost Share of the Defaulting Participant. If the other
Participants decline to pay all of such unpaid Cost Share, the Operator shall be entitled
to pay the unpaid portion thereof. If the other Participants and/or the Operator pay such
unpaid share, then they or it shall be entitled to recover the amount so paid, together
with interest thereon from the date so paid at a per annum rate equal to the Prime Rate
plus 4%, and the provisions of §11.3 shall apply.

Participant may Require
Operations to be Shut Down

10.7 Any Participant holding a 30%
Interest or greater shall be entitled, by notice in writing to the Operator and the other
Participant, to require that operations be suspended if: (a) for a period of 6 consecutive
months such Participant can demonstrate (as set forth in such notice) that

its
Cost Share of Operating Costs has exceeded its proceeds from the sale of Mineral Products;
(b) within 30 days after receipt of such notice, the other Participant has not
demonstrated to the Operator

| | that
its proceeds from the sale of Mineral Products have equalled or exceeded its Cost Share of
Operating Costs during such six month period; and
| | -------------------------------------------------------------------------------------------------------------------------------------------------

|(c) |  | such Participant has provided assurances acceptable to the Operator that the
               Participant is capable of bearing its share of the care and maintenance costs of
               the mine on the Property.
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If such notice is given to the
Operator it shall prepare an Operating Plan for placing the mine on care and maintenance
and shall convene a meeting of the Management Committee to approve such.

Resumption of Operations

10.8 If at any time after the
suspension of operations pursuant to §10.7, the Operator determines that the mine can
be placed back into Commercial Production with the Participants Cost Share of
Operating Costs being not more than 80% of the proceeds which they should realize on the
sale of their share of Mineral Products, the Operator shall prepare an Operating Plan for
the resumption of Operations and shall convene a meeting of the Management Committee to
consider that Operating Plan.

Permanent Suspension

10.9 The Operator, at the direction
of the Management Committee, may at any time following a period of at least one year
during which operations have been continuously suspended under §10.7, by notice to
all Participants holding greater than a 25% Interest, request their agreement to a
permanent termination of operations. Within 90 days after receipt of that notice, each of
such Participants may give notice to the Operator stating that it agrees to the request of
the Operator or that it does not agree. If a Participant fails to give notice within that
90 day period, it shall be deemed to have agreed to the request of the Operator. If one or
more Participants holding greater than a 25% Interest gives notice that it does not agree
to a permanent termination of operations, the Management Committee may elect to have the
Operator resume operations or replace the Operator with another Participant (the objecting
Participants deciding amongst themselves who shall be the Operator), in which case that
Participant shall become the new Operator and shall resume operations. If the Operator has
not resumed operations within one year after the end of the 90 day period, the Management
Committee shall cause the Operator to remove, sell and dispose of the Assets other than
timbers and structures affixed to the underground workings and shafts of the mine as may
be removed pursuant to applicable environmental and mining laws. The net revenues shall be
divided among Participants in proportion to their respective Interests.

Article 11

DISPOSITION OF
PRODUCTION

Taking in Kind

11.1 Each Participant shall, subject
to Article 16, take in kind and separately dispose of its share (in proportion to its
respective Interest) of Mineral Products. However, unless otherwise specified by a
particular Participant, that Participant hereby appoints the Operator as its sole
marketing agent to sell and dispose of its share of Mineral Products and, upon completing
any such sale and disposition on behalf of a Participant, the Operator shall, subject to
Article 16, remit to such Participant its respective share of the proceeds, after making
such deductions as are permitted under §11.2.

Valuing Mineral Products

11.2 For the purposes of determining
the value of Mineral Products taken in kind pursuant to §11.1 or §11.3, each
Participants share of Mineral Products shall be valued and accounted for as of the
time of delivery to or settlement with the purchaser or purchasers thereof, after
deduction of all costs of or related to the marketing thereof, including without
limitation:

|(a) |  | all costs of storage and transportation, including insurance; (b) all
               commissions and discounts;
|--- |  | ---------------------------------------------------------------------------------------------------------------

|(c) |  | such reasonable charge for marketing Mineral Products as is consistent with
               generally accepted industry marketing practices; and
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------

|(d) |  | all taxes (other than income taxes), royalties or other charges or imposts
               provided for pursuant to any law or legal obligation imposed by any government
               if paid by the Operator for the account of such Participant in connection with
               the disposition of Mineral Products hereunder.
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Priority

11.3 If the Operator or a Participant
makes any payment on behalf of a Defaulting Participant pursuant to §10.6, or if a
Participant advances Excess Production Program Overruns pursuant to §9.6, the
Operator or such Participant, as the case may be, shall have the prior and first right to
receive the share of Mineral Products of the Defaulting Participant or the Participant
which did not advance Excess Production Program Overruns, as the case may be, pursuant to
§11.1 until the Operator or such Participant has received Mineral Products in kind of
a value equal to the amount advanced, together with interest thereon at the rate specified
in §9.6 or §10.6, as the case may be.

Accounting by Operator

11.4 Proceeds from the sale by the
Operator of Mineral Products hereunder shall be calculated by the Operator separately for
each Participant at the end of each calendar month and shall be paid monthly within 20
days after the end of each such calendar month following payment to the Operator by each
Participant of its respective Cost Share of Operating Costs outstanding as at the end of
that calendar month, and otherwise subject to Article 16 and the foregoing provisions of
this Article.

Records

11.5 The records relating to Mineral
Products taken in kind or to the calculation of proceeds from the sale thereof may, at the
direction of the Management Committee, be audited annually at the end of each Operating
Year. Any adjustments required by such audit shall be made forthwith and a copy of the
audited statements shall be delivered to the Participants. Any of the Participants shall,
at reasonable times and upon reasonable notice in writing to the Operator, have the right
to inspect, audit and copy the Operators accounts and records relating to the
accounting for Mineral Products taken in kind or to the determination of proceeds from the
sale thereof for any Operating Year within 12 months following the end of such Operating
Year. All such accounts and records shall be deemed to be correct and accurate unless
questioned by a Participant within 12 months following the end of the Operating Year to
which the accounts relate. The Participants shall make all reasonable efforts to conduct
audits in a manner which shall result in a minimum of inconvenience to the Operator.

Non-Arms Length
Sale of Product

11.6 If the Operator or an Affiliate
of the Operator is a purchaser of Mineral Products hereunder, and if the value of such
Mineral Products is used to determine any matter arising under this Article, the Operator
shall be required to receive competitive prices for all Mineral Products so sold.

Article 12, if a party discovers that, in its opinion, another partys publicly
disclosed information (the Prior Disclosure) relating to the Property or work
thereon is inconsistent with the data or other information regarding the Property,

the Prior Disclosure is or could be materially misleading to the public, the discovering
party shall advise the other party of such inconsistency and (a) the other party shall
promptly publish or disseminate, to an extent no less broad than the dissemination

of
the Prior Disclosure, a statement correcting the Prior Disclosure, or

|(b) |  | if the other party fails to promptly disseminate a correcting statement, the

Operator sells its Interest or transfers or assigns its rights under this Agreement to a
third party, its rights and obligations as Operator under this Agreement shall not be
included in such sale unless the third party is capable of assuming and performing the
duties and obligations of the Operator imposed under this Agreement and the consent of all
Participants is first had and obtained, such consent not to be unreasonably withheld.

of §15.1, a Participant may pledge, mortgage, charge or otherwise encumber (in this
paragraph a Charge) the whole or any part of its respective Interest in order
to finance its Cost Share of Production Program Costs and Operating Costs, but only upon
the condition that the holder of such Charge, (in this paragraph a Chargee),
first enters into a written agreement with the other Participants in form satisfactory to
counsel for such other Participants, binding upon the Chargee, to the effect that: (a) the
Chargee shall not enter into possession or institute any proceedings for foreclosure or

Enforcement of Lien by
the Operator

16.2 Such lien in respect of a
Participant who is in default of one or more of its obligations as specified in §16.1
(in this Article 16 a Defaulting Participant) may be enforced by the Operator
against the Defaulting Participant by any one or more of the following:

|(a) |  | the sale or lease (either to one or more of the other Participants, or to a
               third party, but subject to Article 14, save and except for §14.2) of all
               or part of the Interest of the Defaulting Participant for cash or on credit or
               partly for cash and partly on credit;
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(b) |  | the sale of the Defaulting Participants share of Mineral Products for cash
               or on credit or partly for cash and partly on credit;
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------

|(c) |  | the collection and/or retention of receipts due to the Defaulting Participant
               from the sale of Mineral Products or any other Assets and the application of the
               receipts so collected to the obligations, amounts and costs referred to in
               §16.1(d) to §16.1(g), inclusive; or
|--- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(d) |  | without restricting the provisions of §(a), (b) and (c), the exercise by
               the Operator of any other rights and remedies available at law or in equity,
               which may be exercised in the alternative, concurrently or cumulatively.
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the case of the sale of the
Defaulting Participants Interest or the sale of Mineral Products pursuant to
§(a) and (b) respectively, the Defaulting Participant shall execute and deliver to
the purchaser on demand any instrument reasonably necessary to confirm to the purchaser
the title to the property so sold and the Operator is hereby irrevocably authorized by
each Participant to execute on its behalf and in its name any such confirmatory
instrument.

Right of Participant to
Deal With Mineral Product

16.3 The security interest hereby
granted by each Participant to the Operator shall in no way hinder or prevent a
Participant, at any time or from time to time until the security interest hereby
constituted shall have become enforceable pursuant to the provisions of §16.1, from:

|(a) |  | selling, assigning, transferring, conveying or otherwise disposing of all or any
               part of its Mineral Products, free from such security interest, in the ordinary
               course of its business and for the purpose of carrying on the same; provided
               that any forward sale commitment by a Participant shall be without prejudice to
               enforcement by the Operator of its security interest in respect of any Mineral
               Products that have not at the time been delivered to meet that commitment;
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(b) |  | selling, assigning, conveying, transferring or otherwise disposing of all or an
               undivided part of its Interest in accordance with the provisions of Article 14;
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(c) |  | subject always to compliance with the provisions of Article 15, entering into a
               security agreement in accordance with that Article;
|--- |  | --------------------------------------------------------------------------------------------------------------------------------------------------

provided that any such action is not
in breach of any provision of this Agreement.

Participants Lien

16.4 A Participant other than the
Operator which makes a payment on behalf of a defaulting Participant pursuant to
§10.6 or advances a portion of Excess Production Program Overruns on behalf of
another Participant pursuant to §9.6, or has a right to damages pursuant to
§9.7, shall have a lien on the defaulting Participants Interest, the right of
the defaulting Participant to receive either Mineral Products in kind or proceeds from the
sale thereof or from the sale of any other Assets, the interest of the defaulting
Participant in any contracts for the sale of Mineral Products, other Assets and Mineral
Products received in kind by the defaulting Participant, as security for repayment by the
defaulting Participant of all amounts paid or advanced by the Participant pursuant to
§9.6, §10.6 and to which it may be entitled pursuant to §9.7, together with
interest thereon at the rate specified in §9.6, §9.7 or §10.6, as the case
may be.

The lien under this §16.4 shall
rank pari passu with the Operators lien under §16.1 insofar as it secures
amounts referred to in §16.1(f) and subordinate to the lien of the Operator insofar
as it secures amounts referred to in §16.1(d), §16.1(e) or §16.1(g) and the
provisions of §16.2 and §16.3 shall apply with respect thereto mutatis mutandis.

the subject matter herein. This Agreement may not be amended or modified except by an
instrument in writing signed by each of the parties hereto except that amendments to any

               of any proceeds therefrom, net of liabilities, to the Participants to the extent
               of their Interests therein, provided that all reclamation associated with a
               permanent shut-down of the Facilities has been carried out as required by
               applicable laws and regulations.

party, the Defaulting Party has failed to take reasonable steps to cure the default by the
appropriate performance or the Defaulting Party fails to dispute the notice of default.

               payments, a reasonable provision may be made for anticipated Costs for the
               remainder of the Operating Year; and
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(b) |  | calculated by the Operator if it is the sole Participant, or if there is more
               than one Participant, by each Participant as to its respective share of Royalty
               and each Participant and the Operator shall keep separate accounts relating to
               its respective operations related to the Property.
|--- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(a) |  | each payment of Royalty shall be accompanied by an unaudited statement
               indicating the calculation of the Royalty hereunder in reasonable detail and the
               Holder shall receive, within 3 months of the end of each Operating Year, an
               annual summary unaudited statement (an Annual Statement) showing in
               reasonable detail the calculation of the Royalty for the last completed
               Operating Year and showing all credits and deductions added to or deducted from
               the amount due to the Holder;
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(b) |  | the Holder shall have 45 days from the time of receipt of the Annual Statement
               to question the accuracy thereof in writing and, failing such objection, the
               Annual Statement shall be deemed to be correct and unimpeachable thereafter;
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(c) |  | if the Annual Statement is questioned by the Holder, and if such questions
               cannot be resolved between the Holder and the Operator or Participant that
               prepared the Annual Statement, as the case may be, the Holder shall have 12
               months from the time of receipt of the Annual Statement to have such audited,
               which shall initially be at the expense of the Holder;
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(d) |  | the audited Annual Statement shall be final and determinative of the calculation
               of the Royalty for the audited period and shall be binding on the Holder and the
               party that prepared the Annual Statement and any overpayment of Royalty shall be
               deducted from future payments of Royalty and any underpayment of Royalty shall
               be paid to the Holder forthwith;
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(e) |  | the costs of the audit shall be borne by the Holder if the Annual Statement
               overstated the Royalty payable or understated the Royalty payable by not more
               than 1% and shall be borne by the party that prepared the Annual Statement if
               such statement understated the Royalty payable by greater than 1%. If the party
               that prepared the Annual Statement is obligated to pay for the audit it shall
               forthwith reimburse the Holder for any of the audit costs which it had paid; and
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(f) |  | the Holder shall be entitled to examine, on reasonable notice and during normal
               business hours, such books and records as are reasonably necessary to verify the
               payment of the Royalty to it from time to time, provided however that such
               examination shall not unreasonably interfere with or hinder the Operators
               or Participants operations or procedures.
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. |  | Inclusion of Income Taxes in Costs
|-- |  | ----------------------------------

4.1 Notwithstanding anything to the
contrary herein contained, if there is any tax (Tax) on income paid or payable
by a Participant by reason of the fact that the Royalty, in whole or in part, is or
becomes non-deductible to the Participant for the purposes of calculating its taxable
income: (a) if the Royalty is not required to be included in determining the taxable
income of the Holder, the

| | Participant
may deduct from the amount of Royalty otherwise payable by it hereunder, the full amount
of the Tax; and
| | --------------------------------------------------------------------------------------------------------------------

|(b) |  | if the Royalty is in whole or in part required to be included by the Holder in
               its taxable income, the Participant may deduct from the amount of Royalty
               otherwise payable by it hereunder, that percentage of such Tax that equals the
               percentage which the Royalty is of Net Profits in order for the Tax to be shared
               pro rata by the parties.
|--- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

5. Segregation of Property

5.1 The determination of Net Profits
hereunder is based on the premise that production shall be developed solely on the
Property. Other mining properties may be incorporated with the Property into a single
mining project and the metals, ores or concentrates pertaining to each may be blended at
the time of mining or at any time thereafter, provided however, that the respective mining
properties (including the Property) shall bear and have allocated to them their
proportionate part of expenditures relating to the bringing of such single mining project
into commercial production and thereafter operating the same and shall have allocated to
them the proportionate part of the revenues realized from such single operation, all as
determined in accordance with generally accepted accounting principles and from records
maintained by the Operator. The Holder shall have the right, during reasonable business
hours and upon prior notice to the Operator and Participants, to enter upon the mining
properties and to inspect the plant and procedures followed with respect to allocations
made under this paragraph provided that such entry shall be at the sole risk and cost of
the Holder. If the parties disagree on the allocation of actual proceeds received and
deductions therefrom, such shall be referred to arbitration in the manner provided in
Article 17 of the Agreement and the arbitrator shall have reference first to the
Agreement, and then, if necessary, to practices used in mining operations that are of a
similar nature. The arbitrator shall be entitled to retain such independent mining
consultants and financial advisors as he considers necessary. The decision of the
arbitrator shall be final and binding on the parties.
