K.        Disclosures. Each of the Participants represents and warrants that it is unaware of any material facts or circumstances that have not been disclosed in this Agreement, which should be disclosed to the other Participant in order to prevent the representations and warranties in this Article from being materially misleading.

O. Indemnities/Limitation of Liability.

1. Each Participant shall defend, indemnify and hold the other Participant, its directors, officers, employees, agents and attorneys, and Affiliates (collectively “Indemnified Participant”) harmless from and against the entire amount of any Material Loss. A “Material Loss” shall mean all costs, expenses, damages or liabilities, including reasonable attorneys’ fees and other costs of litigation (either threatened or pending) arising out of or based on a breach by a Participant (“Indemnifying Participant”) of any representation, warranty or covenant contained in this Agreement, including without limitation:

(iv)      any Material Loss arising out of Operations conducted by it during the Exploration Period;

(v)       any action taken for or obligation or responsibility assumed on behalf of the other Participant, its directors, officers, employees, agents and attorneys, or Affiliates by a Participant, any of its directors, officers, employees, agents and attorneys, or Affiliates, in violation of Section 4.1;

2. If any claim or demand is asserted against an Indemnified Participant in respect of which such Indemnified Participant may be entitled to indemnification under this Agreement, written notice of such claim or demand shall promptly be given to the Indemnifying Participant. The Indemnified Participant’s failure to provide such notice promptly, however, shall not relieve the Indemnifying Participant of any of its obligations under this Section 3.7 unless the Indemnifying Participant is materially prejudiced by such failure. At the request of any Indemnified Participant, the Indemnifying Participant shall defend the Indemnified Participant against any Liabilities for which the Indemnifying Participant is required to indemnify and hold harmless the Indemnified Parties pursuant to the indemnity provisions set forth in this Agreement. Subject to the Indemnified Participant’s approval, which shall not be unreasonably withheld, delayed or conditioned, the Indemnifying Participant shall retain legal counsel for the purpose of defending any Indemnified Participant in such suit or action. The Indemnified Participant

7

shall have the right to retain legal counsel, at its expense, to participate in the defense of any such suit or action. No such suit or action shall be settled, discontinued, nor shall judgment be permitted to be entered without the written consent of the Indemnified Participant, which consent shall not be unreasonably withheld, delayed or conditioned. Any damages to the assets or business of the Indemnified Participant caused by a failure by the Indemnifying Participant to defend, compromise, or settle a claim or demand in a reasonable and expeditious manner requested by the Indemnified Participant, after the Indemnifying Participant has given notice that it will assume control of the defense, compromise, or settlement of the matter, shall be included in the damages for which the Indemnifying Participant shall be obligated to indemnify the Indemnified Participant. Any settlement or compromise of a matter by the Indemnifying Participant shall include a full release of claims against the Indemnified Participant which has arisen out of the indemnified claim or demand.

CONTRIBUTIONS BY PARTICIPANTS

X.        Exploration Rights and Obligations. During the Exploration Period and subject to Barrick making the Exploration Expenditures as provided in Section 5.2, MGC grants to Barrick the exclusive right to conduct Exploration on the Properties and the option to earn an undivided sixty percent (60%) interest in the Properties.

1. Except as to the first year’s Exploration Expenditures, which is a firm commitment, and subject to Barrick incurring the minimum required annual Exploration Expenditures under Section 5.2 below, Barrick shall have the sole right to determine the nature, timing, scope, extent and method of all Operations during the Exploration Period, without any obligation to hold meetings of the Management Committee, to prepare Programs and Budgets for review, comment or approval by MGC, or to obtain the approval or consent of MGC or the Management Committee. Barrick shall conduct all such Operations in a manner consistent with the standards set forth in the first sentence of Section 8.3, and in

9

conducting such Operations Barrick shall be required to fulfill all of the applicable obligations of the Manager set forth in Subsections 8.2(c), (e), (f), (g(i)), and (q). In addition, until Barrick has completed its Initial Contribution it shall not be entitled (without MGC’s prior written consent) or required to perform the activities described in Subsections 8.2(g), (i), and (l) that would otherwise require consent of the Management Committee or of both participants as applicable. For all such Operations, Barrick shall provide for accrual of reasonably anticipated Environmental Compliance expenses, which may be included as Exploration Expenditures, and upon completion of its Initial Contribution, Barrick shall transfer any accrued but unexpended amounts to the Environmental Compliance Fund established under Paragraph 2.14 of Exhibit B. Prior to completion of its Initial Contribution, Barrick, in lieu of any reporting requirements under Section 8.2, shall:

(i)        within 60 days following each anniversary of the Effective Date, provide MGC with a reasonably detailed written report of all Operations conducted during the preceding Agreement year, with a copy of all data, in digital format, including PDF, JPG, ASCII, DXF, Access, Excel, PowerPoint software/file formats copied to an Annual, Comprehensive Project Data update CD or DVD. The annual report will also include a statement of Exploration Expenditures incurred during the annual period in question (as well as such back-up information as is reasonably necessary for MGC to confirm the reported amounts and nature of the reported Exploration Expenditures) and a summary of the upcoming year’s planned Operations;

(ii)       provide MGC with quarterly update reports, including all material data received during the period, including assays, drill logs and drill hole locations within thirty (30) days following the end of each calendar quarter, which shall include a current estimate of Exploration Expenditures incurred; and

(iii)      make available for inspection and copying by MGC when reasonably requested by MGC all factual data and information and interpretive reports, studies and analyses concerning the Properties, and make all core and other samples available for inspection by MGC.

Barrick makes no representation or warranty, express or implied, as to the accuracy of the data and information provided to MGC in accordance with (i), (ii) and (iii) above, but does represent and warrant that the data and information will be complete, in a form that can be independently verified as per industry standards and timely, and will consist of all of the material data and information available for the periods covered.

2. MGC shall provide Barrick with written notice of any exceptions it may have to the annual statement of Exploration Expenditures submitted to it as provided

10

above within three months after receipt of the statement. Failure to provide such notice within the three-month period shall constitute acceptance by MGC of the stated Exploration Expenditures. During that three-month period, as reasonably requested by MGC, Barrick shall make available to MGC and its representatives all back-up data and information used by Barrick to calculate the reported Exploration Expenditures, in order to allow MGC to confirm the amounts and nature of the reported Exploration Expenditures. If MGC identifies any shortfall in Exploration Expenditures for an annual period, it shall notify Barrick, and the amount of any such shortfall shall be paid by Barrick to MGC within 30 days after Barrick’s receipt of such notice.

3. During the Exploration Period, MGC and its representatives, at MGC’s sole risk and expense, shall have the right, exercisable during regular business hours, at a mutually convenient time, and in a reasonable manner conforming to Barrick’s safety rules and regulations and so as not to unreasonably interfere with Barrick’s operations, to go upon the Properties for the purpose of inspecting those Operations and confirming that Barrick is conducting its Operations in the manner required by this Agreement.

4. Barrick and MGC each agrees to carry such insurance, covering its respective employees conducting Operations at or on the Properties for Barrick, and will fully comply with the requirements of the statutes of the State of Nevada pertaining to worker’s compensation and occupational disease and disabilities as are now in force or as may be hereafter amended or enacted. In addition, during the Exploration Period, Barrick agrees to comply with the insurance standards set forth in Exhibit F.

Y. Barrick’s Obligations During the Exploration Period.

1. During the Exploration Period, to maintain its option to earn a 60% interest in the Properties under this Agreement, Barrick shall incur the amounts of Exploration Expenditures by the dates set forth below. The obligation to incur at least $4,000,000 in Exploration Expenditures during the first period beginning on Effective Date and ending on December 31, 2009 is a firm commitment. In subsequent periods, Barrick is not obligated to make any additional Exploration Expenditures.

Date	Exploration Expenditures	Aggregate
By December 31, 2009	$ 4,000,000	$ 4,000,000
By December 31, 2010	$ 5,000,000	$ 9,000,000
By December 31, 2011	$ 7,000,000	$ 16,000,000
By December 31, 2012	$ 7,000,000	$ 23,000,000
By December 31, 2013	$ 7,000,000	$ 30,000,000

11

2. At its sole discretion, if Barrick has timely incurred the required amounts of Exploration Expenditures to earn a 60% interest in the Properties, then Barrick will have the exclusive option to earn an additional 10% interest in the Properties (70% total) by incurring an additional $8,000,000 in Exploration Expenditures on or before December 31, 2014, for an aggregate of $38,000,000 in Exploration Expenditures. Barrick shall give MGC written notice as to whether or not Barrick intends to earn the additional 10% interest no later than 30 days after earning a 60% interest and confirmation or deemed confirmation by MGC of acceptance of the expenditures. If Barrick fails to timely provide such notice, then Barrick shall be deemed to have made an election not to acquire the additional 10% interest, and the provisions of Subsection 5.4(a)(i) shall apply.

3. If Barrick has timely incurred the required amounts of Exploration Expenditures to earn a 70% interest in the Properties, and MGC has exercised its option to enter into a joint venture pursuant to Subsection 5.4(a), then MGC at its sole discretion will have the exclusive option (the “Carry Option”) to require Barrick to: (i) fund MGC’s proportionate share of the Exploration Expenses in excess of $38,000,000 that are incurred prior to a decision by the Management Committee to approve a Program and Budget for the Development and construction of a mine based on the Management Assessment Study by Barrick; and (ii) arrange financing for MGC Development Costs until the commencement of Commercial Production. If Barrick complies with those obligations, it will earn an additional 5% Participating Interest (75% total). If MGC elects to exercise the Carry Option, MGC shall give Barrick written notice of its election no later than 120 days after MGC has given notice to Barrick of MGC’s confirmation that Barrick has incurred a total of $38,000,000 in Exploration Expenditures. If Barrick earns the additional 5% interest, Barrick shall recover the MGC Development Costs that it incurs, plus accrued interest as described below, from, but only from, 90% of MGC’s share of Products from the Properties. The amount of MGC Development Costs advanced by Barrick shall bear interest from the date incurred until recovered at an annual rate equal to the Prime Rate plus 2%.

4. Any Exploration Expenditures incurred in any period in excess of the amount required for that period shall apply against any future year’s obligation.

5. Except as otherwise set forth in Subsection 5.2(f), in the event of a shortfall in Exploration Expenditures is anticipated by Barrick during any period, Barrick may elect to maintain this Agreement in force by paying to MGC the difference between the required and actual Exploration Expenditures for the period no later than the end of the period.

6. Barrick’s failure to make Exploration Expenditures in accordance with the provisions of Subsection 5.2(a) above, or to pay cash in lieu under Subsections

12

5.1(b) or 5.2(e) above, if not cured within 30 days after notice by MGC of such default, shall be deemed to be a withdrawal of Barrick from the Business, and this Agreement shall terminate. Upon such event, Barrick shall have no further right, title or interest in the Assets and it shall take such actions as are necessary to ensure that all Assets are free and clear of any Encumbrances arising by, through or under it, except for such Encumbrances to which the Participants may have agreed. Subject to Subsection 5.2(g) below, Barrick’s withdrawal shall be effective upon such failure, but such withdrawal shall not relieve Barrick of its obligation to MGC to fund Operations up to the amount of Barrick’s contractual obligations to third parties, nor shall such withdrawal relieve Barrick of its responsibility to fund and satisfy Barrick’s liabilities to third persons (regardless of whether such liabilities accrue before or after such withdrawal), including Environmental Liabilities, Continuing Obligations and Environmental Compliance, arising out of Barrick’s Operations with respect to the Properties under this Agreement prior to Barrick’s withdrawal. In addition, if such failure pertains to the first annual period after the Effective Date, then Barrick shall, at MGC’s election, either (i) pay to MGC the difference between the amount of Exploration Expenditures actually incurred and $4,000,000, although in that event such a payment shall not allow Barrick to maintain the Agreement in force, or (ii) complete the expenditure of the required amount of Exploration Expenditures in a timely and miner-like manner. Except as provided in this Subsection, Barrick’s withdrawal shall relieve Barrick from any other obligation to make contributions hereunder.

7. During the Exploration Period, Barrick shall timely perform or cause to be performed all actions required of MGC under the Mining Leases and other contracts, timely perform or cause to be performed all assessment and other work, and timely pay all payments required under the Mining Leases and other contracts, real property taxes and other costs, including Governmental Fees, required by Law in order to maintain the unpatented mining claims, mill sites, tunnel sites and fee properties included within the Properties, and to timely make all required filings and recordings associated therewith and provide notice to MGC of the same. If Barrick withdraws from or terminates this Agreement on or after May 15^th of any calendar year during the Exploration Period, Barrick shall nonetheless be obligated to timely and properly pay all Governmental Fees required to maintain all of the unpatented mining claims, mill sites and tunnels sites included within the Properties through the next subsequent assessment year, and to timely make all required filings and recordings associated therewith.

8. Barrick acknowledges that there are existing disturbances at the Properties which are subject to existing reclamation obligations, which Barrick shall timely perform in conducting Operations during the Exploration Period. Following the Effective Date, MGC shall, to the extent allowed by applicable Law, maintain each Existing Permit in full force and effect and MGC shall allow Barrick to use

13

and operate under each such Existing Permit until Barrick has obtained a replacement permit (or any alternative permit as it desires) in its own name. Barrick and MGC shall use commercially reasonable efforts to obtain replacements for the Existing Permits (and related Existing Bonds, as defined below) as expeditiously as possible. MGC shall maintain any related bond, letter of credit, guarantee or other security or support required by Law for each such Existing Permit (the “Existing Bonds”) until Barrick has finalized the transfer or replacement of such Existing Permit and any corresponding Existing Bond. Barrick agrees to reimburse MGC for bond premiums, fee payments and other direct costs incurred by MGC in connection with the maintenance of the Existing Permits and the Existing Bonds after the Effective Date, up to the date that the transfer or reissuance of the Existing Permit occurs and the Existing Bond related thereto is released. Such costs (not including any principal amount of any bond) shall constitute Exploration Expenditures hereunder. If MGC receives a notice of violation under any Existing Permit following the Effective Date but before the transfer or replacement of such Existing Permit, which is based on or arises out of the Operations of Barrick after the Effective Date, MGC will promptly notify Barrick, and Barrick shall use commercially reasonable efforts to cure such violation and any obligation or liability associated therewith as provided in Section 3.7 above. If Barrick fails to incur the Exploration Expenditures necessary to earn a 60% interest in the Properties as provided in Section 5.2(a), MGC and Barrick shall use commercially reasonable efforts to obtain replacements in the name of MGC for the Existing Permits and any new permits acquired by Barrick (and related Existing Bonds, or new bonds) as expeditiously as possible.

Z.        Barrick’s Initial Contribution. Barrick shall have the right, but except as provided in Subsection 5.3(a), not the obligation to make the following investments as its Initial Contribution.

1. Upon timely incurring Exploration Expenditures in an amount at least equal to $30,000,000, Barrick shall provide notice thereof to MGC, such notice shall include a statement setting forth the Exploration Expenditures incurred in reasonable detail, and, subject to confirmation by MGC of the amount of Exploration Expenditures incurred, as set forth in Subsection 5.1(a)(i), Barrick shall earn an interest in the Properties to be determined as follows.

(iv)      If Barrick timely incurs Exploration Expenditures in an amount at least equal $30,000,000 during the Exploration Period, in accordance with the provisions of Subsection 5.2(a), but elects not to earn an additional 10% interest, Barrick shall earn a 60% interest in the Properties. MGC shall convey or assign (by special warranty deed or other appropriate conveyance of that nature) to Barrick an undivided 60% interest in the Properties within 10 days after notifying Barrick that it has

14

confirmed that Barrick has timely incurred the required amount of Exploration Expenditures.

(v)       Upon timely incurring Exploration Expenditures in an amount at least equal to $38,000,000, Barrick shall provide notice thereof to MGC and such notice shall include a statement setting forth the Exploration Expenditures incurred in reasonable detail. If Barrick timely incurs Exploration Expenditures of at least $38,000,000 during the Exploration Period, in accordance with the provisions of Subsection 5.2(b), Barrick shall earn a 70% interest in the Properties. MGC shall convey or assign (by special warranty deed or other appropriate conveyance of that nature) to Barrick an undivided 70% interest in the Properties within 10 days after notifying Barrick that it has confirmed that Barrick has timely incurred the required amount of Exploration Expenditures.

(vi)      If Barrick elects to earn an additional 10% interest in the Properties as provided in Subsection 5.2(b), but fails to incur Exploration Expenditures of at least $38,000,000 in the one year immediately following vesting at 60%, then Barrick’s interest in the Properties shall remain at 60% and MGC shall convey or assign (by special warranty deed or other appropriate conveyance of that nature) to Barrick an undivided 60% interest in the Properties within 10 days after receiving notice from Barrick that Barrick did not incur $38,000,000 in the one year immediately following vesting at 60%. The provisions of Section 5.4 shall then apply.

(vii)     Within 45 days of any notice delivered by Barrick pursuant to this Subsection 5.3(a) Barrick shall submit a proposed Budget for Operations going forward from and after the date of such proposal through the commencement of Commercial Production, and a proposed Program and Budget for the next year. With respect to the proposed Program and Budget for the next year only, unless (A) Barrick makes the election to earn an additional interest pursuant to Subsection 5.2(b), or (B) MGC elects not to go forward with a joint venture as provided in Subsection 5.4(d), MGC shall have a period of 75 days (rather than 30 days) to submit the response called for in Section 9.4.

2. If Barrick has earned a 70% interest in the Properties and MGC elects to exercise the Carry Option as provided in Subsection 5.2(c), upon completion of construction of the mine, Barrick shall earn an additional 5% interest in the Properties. Upon the commencement of Commercial Production, Barrick shall provide notice thereof to MGC and such notice shall include a statement setting forth the amount of MGC Development Costs advanced by Barrick in reasonable

15

detail. MGC shall convey or assign to Barrick an undivided 5% interest in the Properties within 10 days after notifying Barrick that it has confirmed that Barrick has timely incurred the required amount of MGC Development Costs advanced by Barrick. MGC shall have the right to audit the amount of reported MGC Development Costs in the same manner as set forth in Subsection 5.1(b).

AA. Joint Venture Option.

1. MGC shall have a period of 120 days from the last of the following events to occur to elect to enter into a joint venture with Barrick with respect to the Properties:

(viii)    upon receipt of notice from Barrick as provided in Subsection 5.3(a), if Barrick elects not to earn an additional 10% interest as provided in Subsection 5.2(b),

(ix)      upon receipt of notice from Barrick as provided in Subsection 5.3(a)(ii), if Barrick elects to and earns an additional 10% interest as provided in Section 5.2(b), or

(x)       upon receipt of notice from Barrick as provided in Subsection 5.3(a)(iii), if Barrick fails to timely incur an additional $8,000,000 in Exploration Expenditures.

2. MGC shall exercise its option to enter into a joint venture by written notice to Barrick. If MGC fails to give notice to Barrick within the applicable 120-day period, MGC shall be deemed to have elected to enter into a joint venture with Barrick with respect to the Properties.

3. If MGC elects or is deemed to have elected to enter into a joint venture this Agreement shall govern the relationship, obligations and rights of the Participants in the joint venture and the following shall occur.

(xi)      As its Initial Contribution, MGC shall contribute the Assets described in Exhibit A to the purposes of this Agreement.

(xii)     As its Initial Contribution, Barrick shall contribute its funding of Exploration Expenditures to the purposes of this Agreement.

(xiii)    The Participants’ Participating Interests and Equity Accounts shall be established as follows:

(A)      If Barrick has incurred a total of $30,000,000 in Exploration Expenditures and has earned a 60% interest in the Properties, then the Participating Interests of the Participants shall be:

16

Barrick – 60%

MGC – 40%

and the amounts of $36,000,000 and $24,000,000 shall be credited to Barrick’s and MGC’s Equity Accounts, respectively.

(B)      If Barrick has incurred a total of $38,000,000 in Exploration Expenditures and has earned a 70% interest in the Properties, then the Participating Interests of the Participants shall be:

Barrick – 70%

MGC – 30%

and the amounts of $44,000,000 and $19,000,000 shall be credited to Barrick’s and MGC’s Equity Accounts, respectively.

(xiv) Barrick shall become the Manager of the Business.

4. If MGC elects not to enter into a joint venture, then one of the following will occur:

(xv)     Barrick shall have the option to purchase MGC’s interest in the Assets, which Barrick shall elect by notice to MGC within 365 days after MGC elects not to enter into a joint venture. If Barrick fails to provide notice to MGC within the 365-day period, Barrick shall be deemed to have elected not to purchase MGC’s interest in the Assets. If Barrick elects to purchase MGC’s interest in the Assets, then there shall be a closing within 30 days of Barrick’s notice. At the closing, Barrick shall pay to MGC $40,000,000 and grant to MGC a 2% Net Smelter Return Royalty on Production from the Properties and MGC shall convey and assign (by special warranty deed or other appropriate conveyance of that nature) all of its interests in the Assets to Barrick.

(xvi)    If Barrick elects not to purchase MGC’s interest in the Assets, then the joint venture shall be formed as provided in Subsection 5.4(c). In that event, (A) MGC shall be deemed to have exercised the Carry Option, effective as of the date of its original notice to Barrick electing not to enter into a joint venture, and (B) MGC’s share of any costs of Operations incurred by Barrick during the 365-day period referred to in Subsection 5.4(d)(i) shall be MGC Development Costs.

5. During the 120-day period referred to in Subsection 5.4(a), Barrick may continue to fund Operations. If MGC elects to enter into a joint venture, MGC’s share of the costs of such Operations shall be treated as MGC Development Costs.

17

BB.     Additional Contributions. At such time as Barrick has contributed the full amount of its Initial Contribution, the Participants, subject to MGC’s right to exercise the Carry Option and any election permitted by Subsection 9.5(a), shall be obligated to contribute funds to adopted Programs and Budgets in proportion to their respective Participating Interests.

CC.     Alternative Programs and Budgets. After completion by Barrick of its Initial Contribution, and if MGC has not elected to exercise the Carry Option, whenever Barrick proposes a Program and Budget for any annual period of less than $350,000, MGC shall have a period of 30 days from and after its receipt of such a proposed Program and Budget to propose a substitute Program and Budget that calls for expenditures in excess of $350,000. If Barrick elects not to participate in that substitute Program and Budget at a level that is in accordance with its Participating Interest (with respect to any substitute Program and Budget, Barrick shall have the right only to participate fully in any such substitute Program and Budget, or not at all), then MGC may elect to require the Management Committee to adopt that Program and Budget, and in that event MGC’s Participating Interest shall be increased by one percentage point for each complete $500,000 increment spent by it pursuant to that substitute Program and Budget. By way of example (but not limitation), if Barrick had elected only to earn a 60% Participating Interest, and if during the relevant time period MGC proposed a substitute Program and Budget calling for expenditures of $1,000,000, and Barrick elected not to participate, upon completion and full funding of that Program and Budget, MGC’s Participating Interest would automatically increase from 40% to 42%, and Barrick’s Participating Interest would automatically decrease from 60% to 58%. Subsequently, if MGC proposed a substitute Program and Budget calling for expenditures of $2,500,000, and Barrick elected not to participate, upon completion and full funding of that Program and Budget MGC’s Participating Interest would automatically increase from 42% to 45%, and Barrick’s Participating Interest would automatically decrease from 58% to 55%. The provisions of this Section 5.6 shall apply until such time, if any, as MGC has increased its Participating Interest to at least 70%. Thereafter, the standard dilution formula (as described in Section 9.5) shall apply.

ARTICLE VI

INTERESTS OF PARTICIPANTS

DD.     Changes in Participating Interests. Upon formation of the joint venture, the Participating Interests shall be eliminated or changed as follows:

1. Upon completion by Barrick of the obligations set forth in Subsection 5.2(b) or Subsection 5.2(c);

2. Upon withdrawal or deemed withdrawal as provided in Section 6.2 and Article XII;

3. Upon an election by either Participant pursuant to Section 9.5 to contribute less to an adopted Program and Budget than the percentage equal to its Participating Interest, or to contribute nothing to an adopted Program and Budget;

18

4. In the event of default by either Participant in making its agreed-upon contribution to an adopted Program and Budget, followed by an election by the other Participant to invoke any of the remedies in Section 10.5;

5. Upon Transfer by either Participant of part or all of its Participating Interest in accordance with Article XV; or

6. Upon acquisition by either Participant of part or all of the Participating Interest of the other Participant, however arising.

EE. Elimination of Minority Interest.

1. If MGC’s Participating Interest becomes less than 10% MGC shall be deemed to have withdrawn from the Business and to have assigned to Barrick all of its Participating Interest free and clear of any Encumbrances arising by, through or under MGC, except any such Encumbrances listed in Exhibit A or to which the Participants have agreed. Such relinquished Participating Interest shall be deemed to have accrued automatically to Barrick. However, MGC shall be deemed to have reserved a Net Smelter Return Royalty of 2%. The right to receive a Net Smelter Return Royalty under this Subsection 6.2(a) may be transferred by MGC to any third party.

2. In addition to the provisions of Subsection 6.2(a), a Reduced Participant whose Recalculated Participating Interest is reduced to 10% shall be deemed to have withdrawn from the Business and shall relinquish its entire Participating Interest free and clear of any Encumbrances arising by, through or under the Reduced Participant, except any such Encumbrances listed in Exhibit A or to which the Participants have agreed. Such relinquished Participating Interest shall be deemed to have accrued automatically to the other Participant. The Reduced Participant shall have the right to receive 10% of Net Proceeds, if any, to a maximum amount of 75% percent of the Reduced Participant’s Equity Account balance as of the effective date of the withdrawal. Upon receipt of such amount, and subject to Section 6.3, the Reduced Participant shall thereafter have no further right, title, or interest in the Assets or under this Agreement. In such event, the Reduced Participant shall execute and deliver an appropriate conveyance of all of its right, title and interest in the Assets to the remaining Participant.

3. The relinquishment, withdrawal and entitlements for which this Section provides shall be effective as of the effective date of the recalculation under Sections 9.5 or 10.5. However, if the final adjustment provided under Section 9.6 for any recalculation under Section 9.5 results in a Recalculated Participating Interest of ten percent (10%) or more: (i) the Recalculated Participating Interest shall be deemed, effective retroactively as of the first day of the Program Period, to have automatically revested; (ii) the Reduced Participant shall be reinstated as a Participant, with all of the rights and obligations pertaining thereto; (iii) the right

19

to a Net Smelter Returns Royalty (if applicable) and Net Proceeds under Subsection 6.2(a) shall terminate; and (iv) the Manager, on behalf of the Participants, shall make any necessary reimbursements, reallocations of Products, contributions and other adjustments as provided in Subsection 9.6(d). Similarly, if such final adjustment under Section 9.6 results in a Recalculated Participating Interest for either Participant of less than ten percent (10%) for a Program Period as to which the provisional calculation under Section 9.5 had not resulted in a Participating Interest of less than ten percent (10%), then such Participant, at its election within thirty (30) days after notice of the final adjustment, may contribute an amount resulting in a revised final adjustment and resultant Recalculated Participating Interest as provided for in Section 9.6. If no such election is made, such Participant shall be deemed to have withdrawn under the terms of Subsection 6.2(b) as of the beginning of such Program Period, and the Manager, on behalf of the Participants, shall make any necessary reimbursements, reallocations of Products, contributions and other adjustments as provided in Subsection 9.6(d), including of any Net Proceeds, or any Net Smelter Returns (if applicable) to which such Participant may be entitled for such Program Period.

FF.      Continuing Liabilities Upon Adjustments of Participating Interests. Any reduction or elimination of either Participant’s Participating Interest under Section 6.2 shall not relieve such Participant of its share of any liability, including, without limitation, Continuing Obligations, Environmental Liabilities and Environmental Compliance, whether arising, before or after such reduction or elimination, out of acts or omissions occurring or conditions existing prior to the Effective Date or out of Operations conducted during the term of this Agreement but prior to such reduction or elimination, regardless of when any funds may be expended to satisfy such liability. For purposes of this Section, such Participant’s share of such liability shall be equal to its Participating Interest at the time the act or omission giving rise to the liability occurred, or, as to such liability arising out of acts or omissions occurring or conditions existing prior to the Effective Date, equal to such Participant’s initial Participating Interest. Should the cumulative cost of satisfying Continuing Obligations be in excess of cumulative amounts accrued or otherwise charged to the Environmental Compliance Fund as described in Exhibit B, each of the Participants shall be liable for its proportionate share (i.e., Participating Interest at the time of the act or omission giving rise to such liability occurred of the cost of satisfying such Continuing Obligations, notwithstanding that either Participant has previously withdrawn from the Business or that its Participating Interest has been reduced or converted to an interest in Net Proceeds pursuant to Subsection 6.2(b)).

GG.     Documentation of Adjustments to Participating Interests. Adjustments to the Participating Interests need not be evidenced during the term of this Agreement by the execution and recording of appropriate instruments, but each Participant’s Participating Interest and related Equity Account balance shall be shown in the accounting records of the Manager, and any adjustments thereto shall be made monthly. However, either Participant, at any time upon the request of the other Participant, shall execute and acknowledge instruments necessary to

20

evidence such adjustments in form sufficient for filing and recording in the jurisdiction where the Properties are located.

HH. Grant of Lien and Security Interest.

1. Subject to Section 6.6, and effective only upon completion by Barrick of its Initial Contribution, each Participant grants to the other Participant a lien upon and a security interest in its Participating Interest, including all of its right, title and interest in the Assets, whenever acquired or arising, and the proceeds from and accessions to the foregoing; provided, however, that where a Participant’s Participating Interest is adjusted pursuant to the provisions of Section 10.5 below, then notwithstanding any other provision of this Agreement, the non-contributing Participant shall have no further liability to the other Participant for the amount which caused the adjustment.

2. The liens and security interests granted by Subsection 6.5(a) shall secure every obligation or liability of the Participant granting such lien or security interest created under this Agreement, including the obligation to repay a Cover Payment in accordance with Section 10.4. Each Participant hereby agrees to take all action necessary to perfect such lien and security interest and hereby appoints the other Participant its attorney-in-fact to execute, file and record all financing statements and other documents necessary to perfect or maintain such lien and security interest.

II.        Subordination of Interests. Each Participant shall, from time to time, take all necessary actions, including execution of appropriate agreements, to pledge and subordinate its Participating Interest, any liens it may hold which are created under this Agreement other than those created pursuant to Section 6.5 hereof, and any other right or interest it holds with respect to the Assets (other than any statutory lien of the Manager) to any secured borrowings for Operations approved by the Management Committee, including any secured borrowings relating to Project Financing, and any modifications or renewals thereof.

ARTICLE VII

MANAGEMENT COMMITTEE

JJ.        Organization and Composition. If a joint venture is formed as provided in Section 5.4, the Participants will establish a Management Committee to determine overall policies, objectives, procedures, methods and actions under this Agreement. The Management Committee shall consist of two members appointed by MGC and two members appointed by Barrick. Each Participant may appoint one or more alternates to act in the absence of a regular member. Any alternate so acting shall be deemed a member. Appointments by a Participant shall be made or changed by notice to the other members. Barrick shall designate one of its members to serve as the chair of the Management Committee.

21

1. Decisions. After Barrick has completed its Initial Contribution, each Participant, acting through its appointed member(s) in attendance at the meeting, shall have the votes on the Management Committee in proportion to its Participating Interest. Unless otherwise provided in this Agreement, the vote of the Participant with a Participating Interest over 50% shall determine the decisions of the Management Committee. Provided however that the following decision will require a unanimous vote of the participants: Acquisition of any asset for the Business which would materially change the conduct of the business as contemplated by this agreement.

KK. Meetings.

(a)       After Barrick has completed its Initial Contribution, the Management Committee shall hold regular meetings at least quarterly in Elko, Nevada, or at other agreed places. The Manager shall give 10 days notice to the Participants of such meetings. Additionally, either Participant may call a special meeting upon seven days notice to the other Participant. In case of an emergency, reasonable notice of a special meeting shall suffice. There shall be a quorum if at least one member representing each Participant is present; provided, however, that if a Participant fails to attend two consecutive properly called meetings, then a quorum shall exist at the second meeting if the other Participant is represented by at least one appointed member, and a vote of such Participant shall be considered the vote required for the purposes of the conduct of all business properly noticed unless such vote would otherwise require unanimity.

1. If business cannot be conducted at a regular or special meeting due to the lack of a quorum, either Participant may call the next meeting upon two days notice to the other Participant.

2. Each notice of a meeting shall include an itemized agenda prepared by the Manager in the case of a regular meeting or by the Participant calling the meeting in the case of a special meeting, but any matters may be considered if either Participant adds the matter to the agenda at least five days before the meeting or with the consent of the other Participant. The Manager shall prepare minutes of all meetings and shall distribute copies of such minutes to the other Participant within 30 days after the meeting. Either Participant may electronically record the proceedings of a meeting with the consent of the other Participant. The other Participant shall sign and return or object to the minutes prepared by the Manager within 30 days after receipt, and failure to do either shall be deemed acceptance of the minutes as prepared by the Manager. The minutes, when signed or deemed accepted by both Participants, shall be the official record of the decisions made by the Management Committee. Decisions made at a Management Committee meeting shall be implemented in accordance with adopted Programs and Budgets. If a Participant timely objects to minutes proposed by the Manager, the members of the Management Committee shall seek, for a period not to exceed 30 days from receipt by the Manager of notice of the objections, to agree upon minutes

22

acceptable to both Participants. If the Management Committee does not reach agreement on the minutes of the meeting within such 30 day period, the minutes of the meeting as prepared by the Manager together with the other Participant’s proposed changes shall collectively constitute the record of the meeting. If personnel employed in Operations are required to attend a Management Committee meeting, reasonable costs incurred in connection with such attendance shall be charged to the Business Account. All other costs shall be paid by the Participants individually.

LL.      Action Without Meeting in Person. In lieu of meetings in person, the Management Committee may conduct meetings by telephone or video conference, so long as minutes of such meetings are prepared in accordance with Subsection 7.3(c). The Management Committee may also take actions in writing signed by all members.

MM.    Matters Requiring Approval. Except as provided in Subsection 5.1(a) and as otherwise delegated to the Manager in Section 8.2, the Management Committee shall have exclusive authority to determine all matters related to overall policies, objectives, procedures, methods and actions under this Agreement.

ARTICLE VIII

7. (i) The Manager shall notify the other Participant promptly of any litigation, arbitration or administrative proceeding commenced against the Business or with regard to the Assets or Operations. (ii) The Manager shall prosecute and defend, but shall not initiate without consent of the Management Committee, all litigation or administrative proceedings arising out of Operations. The non-managing Participant shall have the right to participate, at its own expense, in such litigation

Without the prior authorization from both Participants, the Manager shall not (i) begin a liquidation of the Business; or (ii) dispose of all or a substantial part of the Assets necessary to achieve the purposes of the Business.

10. The Manager shall have the right to carry out its responsibilities hereunder through agents, Affiliates or independent contractors.

11. The Manager shall perform or cause to be performed all assessment and other work, and shall pay all Governmental Fees required by Law in order to maintain the unpatented mining claims, mill sites and tunnel sites included within the Properties. The Manager shall have the right to perform the assessment work required hereunder pursuant to a common plan of exploration and continued actual occupancy of such claims and sites shall not be required. The Manager shall not be liable on account of any determination by any court or governmental agency that the work performed by the Manager does not constitute the required annual assessment work or occupancy for the purposes of preserving or maintaining ownership of the claims, provided that the work done is pursuant to an adopted Program and Budget and is performed in accordance with the Manager’s standard of care under Section 8.3. The Manager shall timely record with the appropriate county and file with the appropriate United States agency any required affidavits, notices of intent to hold and other documents in proper form attesting to the payment of Governmental Fees, the performance of assessment work or intent to hold the claims and sites, in each case in sufficient detail to reflect compliance with the requirements applicable to each claim and site. The Manager shall not be liable on account of any determination by any court or governmental agency that any such document submitted by the Manager does not comply with applicable requirements, provided that such document is prepared and recorded or filed in accordance with the Manager’s standard of care under Section 8.3.

25

The Manager shall keep and maintain all required accounting and financial records pursuant to the procedures described in Exhibit B and in accordance with customary cost accounting practices in the mining industry, and shall ensure appropriate separation of accounts unless otherwise agreed by the Participants.

14. The Manager shall maintain Equity Accounts for each Participant. Each Participant’s Equity Account shall be credited with the value of such Participant’s contributions under Subsections 5.4(c), and shall be credited with amounts credited by each Participant under Section 5.3, or on behalf of MGC pursuant to Subsection 5.2(c). Each Participant’s Equity Account shall be charged with the cash and the fair market value of property distributed to such Participant (net of liabilities assumed by such Participant and liabilities to which such distributed property is subject). Contributions and distributions shall include all cash contributions or distributions plus the agreed value (expressed in dollars) of all in-kind contributions or distributions. Solely for purposes of determining the Equity Account balances of the Participants, the value of all Products distributed to the Participants shall be calculated based on the Spot Price for such Products on the date such Products are shipped to a smelter or refiner, and such value shall be used regardless of the actual amount received by each Participant upon disposition of such Products. 

15. Subject to Subsection 5.1(a), the Manager shall keep the Management Committee advised of all Operations by submitting in writing to the members of the Management Committee: (i) monthly progress reports that include statements of expenditures and comparisons of such expenditures to the adopted Budget; (ii) periodic summaries of data acquired; (iii) copies of reports concerning Operations; (iv) a detailed final report within 60 days after completion of each Program and Budget, which shall include comparisons between actual and budgeted expenditures and comparisons between the objectives and results of Programs; and (v) such other reports as any member of the Management

26

Committee may reasonably request. Subject to Article XVII, at all reasonable times the Manager shall provide the Management Committee, or other representative of a Participant upon the request of such Participant’s member of the Management Committee, access to, and the right to inspect and, at such Participant’s cost and expense, copies of the Existing Data and all maps, drill logs and other drilling data, core, pulps, reports, surveys, assays, analyses, production reports, operations, technical, accounting and financial records, and other Business Information, to the extent preserved or kept by the Manager, subject to Article XVII. In addition, the Manager shall allow the non-managing Participant, at the latter’s sole risk, cost and expense, and subject to reasonable safety regulations, to inspect the Assets and Operations at all reasonable times, so long as the non-managing Participant does not unreasonably interfere with Operations.

16. The Manager shall prepare an Environmental Compliance plan for all Operations consistent with the requirements of any applicable Laws or contractual obligations and shall include in each Program and Budget sufficient funding to implement the Environmental Compliance plan and to satisfy the financial assurance requirements of any applicable Law or contractual obligation pertaining to Environmental Compliance.

17. The Manager shall undertake to perform Continuing Obligations when and as economic and appropriate, whether before or after termination of the Business. The Manager shall have the right to delegate performance of Continuing Obligations to persons having demonstrated skill and experience in relevant disciplines. As part of each Program and Budget submittal, the Manager shall specify in such Program and Budget the measures to be taken for performance of Continuing Obligations and the cost of such measures. The Manager shall keep the other Participant reasonably informed about the Manager’s efforts to discharge Continuing Obligations. Authorized representatives of each Participant shall have the right from time to time to enter the Properties to inspect work directed toward satisfaction of Continuing Obligations and audit books, records, and accounts related thereto.

18. The funds that are to be deposited into the Environmental Compliance Fund shall be maintained by the Manager in a separate, interest bearing cash management account, which may include, but is not limited to, money market investments and money market funds, and/or in longer term investments if approved by the Management Committee. Such funds shall be used solely for Environmental Compliance and Continuing Obligations, including the committing of such funds, interests in property, insurance or bond policies, or other security to satisfy Laws regarding financial assurance for the reclamation or restoration of the Properties, and for other Environmental Compliance requirements.

27

19. If Participating Interests are adjusted in accordance with this Agreement the Manager shall propose from time to time one or more methods for fairly allocating costs for Continuing Obligations in a manner consistent with Article VI.

20. The Manager shall undertake all other activities reasonably necessary to fulfill the foregoing, and to implement the policies, objectives, procedures, methods and actions determined by the Management Committee pursuant to Section 7.1.

PP.      Standard of Care. The Manager shall discharge its duties under Section 8.2 and conduct all Operations in a good, workmanlike and efficient manner, in accordance with sound mining and other applicable industry standards and practices, and in accordance with Laws and with the terms and provisions of leases, licenses, permits, contracts and other agreements pertaining to the Assets. So long as it is performing all of its obligations under this Agreement, the Manager shall not be liable to the other Participant for any act or omission resulting in damage or loss except to the extent caused by or attributable to the Manager’s willful misconduct or gross negligence. The Manager shall not be in default of any of its duties under Section 8.2 if its inability or failure to perform results from the failure of the other Participant to perform acts or to contribute amounts required of it by this Agreement.

QQ.     Resignation; Deemed Offer to Resign. The Manager may resign upon not less than three months’ prior notice to the other Participant, in which case the other Participant may elect to become the new Manager by notice to the resigning Participant within 30 days after the notice of resignation. If any of the following shall occur, the Manager shall be deemed to have resigned upon the occurrence of the event described in each of the following Subsections, with the successor Manager to be appointed by the other Participant at a subsequently called meeting of the Management Committee, at which the Manager shall not be entitled to vote. The other Participant may appoint itself or a third party as the Manager.

1. The aggregate Participating Interest of the Manager and its Affiliates becomes less than 50%;

2. The Manager fails to perform a material obligation imposed upon it under this Agreement and such failure continues for a period of 60 days after notice from the other Participant demanding performance;

3. The Manager fails to pay or contest in good faith its bills and Business debts as such obligations become due;

4. A receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official for a substantial part of its assets is appointed and such appointment is neither made ineffective nor discharged within 60 days after the making thereof, or such appointment is consented to, requested by, or acquiesced in by the Manager;

28

5. The Manager commences a voluntary case under any applicable bankruptcy, insolvency or similar law now or hereafter in effect; or consents to the entry of an order for relief in an involuntary case under any such law or to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or other similar official of any substantial part of its assets; or makes a general assignment for the benefit of creditors; or takes corporate or other action in furtherance of any of the foregoing; or

6. Entry is made against the Manager of a judgment, decree or order for relief affecting its ability to serve as Manager, or a substantial part of its Participating Interest or its other assets by a court of competent jurisdiction in an involuntary case commenced under any applicable bankruptcy, insolvency or other similar law of any jurisdiction now or hereafter in effect.

Under Subsections (d), (e) or (f) above, the appointment of a successor Manager shall be deemed to pre-date the event causing a deemed resignation.

RR.     Payments To Manager. The Manager shall be compensated for its services and reimbursed for its costs hereunder in accordance with Exhibit B.

SS.      Transactions With Affiliates. If the Manager engages Affiliates to provide services hereunder, it shall do so on terms no less favorable than would be the case in arm’s-length transactions with unrelated persons.

TT.      Activities During Deadlock. If the Management Committee for any reason fails to adopt an Exploration, Pre-Feasibility Study, Management Assessment Study or Development Program and Budget, the Manager shall continue Operations at levels sufficient to maintain the Properties. If the Management Committee for any reason fails to adopt an initial Mining Program and Budget or any Expansion or Modification Programs and Budgets, the Manager shall continue Operations at levels sufficient to maintain the then current Operations and Properties. If the Management Committee for any reason fails to adopt Mining Programs and Budgets subsequent to the initial Mining Program and Budget, subject to the contrary direction of the Management Committee and receipt of necessary funds, the Manager shall continue Operations at levels comparable with the last adopted Mining Program and Budget. All of the foregoing shall be subject to the contrary direction of the Management Committee and the receipt of necessary funds.

ARTICLE IX

PROGRAMS AND BUDGETS

UU.     Initial Program and Budget. Upon the formation of the joint venture, Barrick shall prepare and submit to the Participants an Initial Program and Budget which will be reviewed and approved as provided in this Article IX.

29

VV.     Operations Pursuant to Programs and Budgets. Except as otherwise provided in Subsection 5.2, Section 9.12, and Article XII, Operations shall be conducted, expenses shall be incurred, and Assets shall be acquired only pursuant to adopted Programs and Budgets. Every Program and Budget adopted pursuant to this Agreement shall provide for accrual of reasonably anticipated Environmental Compliance expenses for all Operations contemplated under the Program and Budget.

WW.   Presentation of Programs and Budgets. Proposed Programs and Budgets shall be prepared by the Manager for a period of one year or any other shorter period as approved by the Management Committee, and shall be submitted to the Management Committee for review and consideration. All proposed Programs and Budgets may include Exploration, Pre-Feasibility Studies, Management Assessment Study, Development, Mining and Expansion or Modification Operations components, or any combination thereof, and shall be reviewed and adopted upon a vote of the Management Committee in accordance with Sections 7.2 and 9.4. Each Program and Budget adopted by the Management Committee, regardless of length, shall be reviewed at least once a year at a meeting of the Management Committee. During the period encompassed by any Program and Budget, and at least two months prior to its expiration, a proposed Program and Budget for the succeeding period shall be prepared by the Manager and submitted to the Management Committee for review and consideration.

XX.     Review and Adoption of Proposed Programs and Budgets. Within 30 days after submission of a proposed Program and Budget, each Participant shall submit in writing to the Management Committee:

1. Notice that the Participant approves any or all of the components of the proposed Program and Budget;

2. Modifications proposed by the Participant to the components of the proposed Program and Budget; or

3. Notice that the Participant rejects any or all of the components of the proposed Program and Budget.

If a Participant fails to give any of the foregoing responses within the allotted time, the failure shall be deemed to be a vote by the Participant for adoption of the Manager’s proposed Program and Budget. If a Participant makes a timely submission to the Management Committee pursuant to Subsections 9.4(a), (b) or (c), then the Manager working with the other Participant shall seek for a period of time not to exceed 20 days to develop a complete Program and Budget acceptable to both Participants. The Manager shall then call a Management Committee meeting in accordance with Section 7.3 for purposes of reviewing and voting upon the proposed Program and Budget.

30

YY. Election to Participate.

1. By notice to the Management Committee within 20 days after the final vote adopting a Program and Budget, and notwithstanding its vote concerning adoption of a Program and Budget, a Participant may elect to participate in the approved Program and Budget: (i) in proportion to its respective Participating Interest, (ii) in some lesser amount than its respective Participating Interest, or (iii) not at all. In case of an election under Subsection 9.5(a)(ii) or (iii), its Participating Interest shall be recalculated as provided in Subsection 9.5(b) below, with dilution effective as of the first day of the Program Period for the adopted Program and Budget, provided that such Program and Budget is actually completed. If a Participant fails to so notify the Management Committee of the extent to which it elects to participate, the Participant shall be deemed to have elected to contribute to such Program and Budget in proportion to its respective Participating Interest as of the beginning of the Program Period.

2. If a Participant elects to contribute to an adopted Program and Budget some lesser amount than in proportion to its respective Participating Interest, or not at all, and the other Participant elects to fund all or any portion of the deficiency, the Participating Interest of the Reduced Participant shall be recalculated as follows:

(i)        for an election made before Payout, by dividing: (A) the sum of (1) the amount credited to the Reduced Participant’s Equity Account with respect to its Initial Contribution under Section 5.4(c)(iii), (2) the amount of all of the Reduced Participant’s contributions under Section 5.5, and (3) the amount, if any, the Reduced Participant elects to contribute to the adopted Program and Budget; by (B) the sum of (1), (2) and (3) above for both Participants; and then multiplying the result by one hundred; or

(ii)       for an election made after Payout, by reducing its Participating Interest in an amount equal to two times the amount by which it would have been reduced under Subsection 9.5(b)(i) if such election were made before Payout.

The Participating Interest of the other Participant shall be increased by the amount of the reduction in the Participating Interest of the Reduced Participant, and if the other Participant elects not to fund the entire deficiency, the Manager shall adjust the Program and Budget to reflect the funds available.

3. Whenever the Participating Interests are recalculated pursuant to this Subsection 9.5, (i) the Equity Accounts of both Participants shall be revised to bear the same ratio to each other as their recalculated Participating Interests.

31

ZZ.      Recalculation or Restoration of Reduced Interest Based on Actual Expenditures.

1. If a Participant makes an election under Subsection 9.5(a)(ii) or (iii), then within 30 days after the conclusion of such Program and Budget, the Manager shall report the total amount of money expended plus the total obligations incurred by the Manager for such Budget.

2. If the Manager expended or incurred obligations that were more or less than the adopted Budget, the Participating Interests shall be recalculated pursuant to Subsection 9.5(b) by substituting each Participant’s actual contribution to the adopted Budget for that Participant’s estimated contribution at the time of the Reduced Participant’s election under Subsection 9.5(a).

3. If the Manager expended or incurred obligations of less than seventy-five percent (75%) of the adopted Budget, within 60 days of receiving the Manager’s report on expenditures, the Reduced Participant may notify the other Participant of its election to reimburse the other Participant for the difference between any amount contributed by the Reduced Participant to such adopted Program and Budget and the Reduced Participant’s proportionate share (at the Reduced Participant’s former Participating Interest) of the actual amount expended or incurred for the Program, plus interest on the difference accruing at the Prime Rate plus two percentage points. The Reduced Participant shall deliver the appropriate amount (including interest) to the other Participant with such notice. Failure of the Reduced Participant to so notify and tender such amount shall result in dilution occurring in accordance with this Article IX and shall bar the Reduced Participant from its rights under this Subsection 9.6(c) concerning the relevant adopted Program and Budget.

4. All recalculations under this Article IX shall be effective as of the first day of the Program Period for the Program and Budget. The Manager, on behalf of both Participants, shall make such reimbursements, reallocations of Products, contributions and other adjustments as are necessary so that, to the extent possible, each Participant will be placed in the position it would have been in had its Participating Interests as recalculated under this Section been in effect throughout the Program Period for such Program and Budget. If the Participants are required to make contributions, reimbursements or other adjustments pursuant to this Section, the Manager shall have the right to purchase or sell a Participant’s share of Products in the same manner as under Section 11.2 and to apply the proceeds of such sale to satisfy that Participant’s obligation to make such contributions, reimbursements or adjustments.

5. Whenever the Participating Interests are recalculated pursuant to this Section, the Participants’ Equity Accounts shall be revised to bear the same ratio to each other as their Recalculated Participating Interests.

32

AAA. Pre-Feasibility Study Program and Budgets.

1. At such time as either Participant is of the good faith and reasonable opinion that economically viable Mining Operations may be possible on the Properties, the Participant may propose to the Management Committee that a Pre-Feasibility Study Program and Budget, or a Program and Budget that includes Pre-Feasibility Studies, be prepared. Such proposal shall be made in writing to the other Participant, shall reference the data upon which the proposing Participant bases its opinion, and shall call a meeting of the Management Committee pursuant to Section 7.3. If such proposal is adopted by the Management Committee, the Manager shall prepare or have prepared a Pre-Feasibility Study Program and Budget as approved by the Management Committee and shall submit the same to the Management Committee within 60 days following adoption of the proposal.

2. Pre-Feasibility Studies may be conducted by the Manager, Feasibility Contractors, or both, or may be conducted by the Manager and audited by Feasibility Contractors, as the Management Committee determines. A Pre-Feasibility Study Program shall include the work necessary to prepare and complete the Pre-Feasibility Study approved in the proposal adopted by the Management Committee, which may include some or all of the following:

(iii)      analyses of various alternatives for mining, processing and beneficiation of Products;

(iv)      analyses of alternative mining, milling, and production rates;

(v)       analyses of alternative sites for placement of facilities (i.e., water supply facilities, transport facilities, reagent storage, offices, shops, warehouses, stock yards, explosives storage, handling facilities, housing, public facilities);

(vi)      analyses of alternatives for waste treatment and handling (including a description of each alternative of the method of tailings disposal and the location of the proposed disposal site);

(vii)     estimates of recoverable proven and probable reserves of Products and of related substances, in terms of technical and economic constraints (extraction and treatment of Products), including the effect of grade, losses, and impurities, and the estimated mineral composition and content thereof, and review of mining rates commensurate with such reserves;

(viii)    analyses of environmental impacts of the various alternatives, including an analysis of the permitting, environmental

33

liability and other Environmental Law implications of each alternative, and costs of Environmental Compliance for each alternative;

(ix)      conduct of appropriate metallurgical tests to determine the efficiency of alternative extraction, recovery and processing techniques, including an estimate of water, power, and reagent consumption requirements;

(x)       conduct of hydrology and other studies related to any required dewatering; and

(xi)      conduct of other studies and analyses approved by the Management Committee.

3. The Manager shall have the discretion to base its and any Feasibility Contractors’ Pre-Feasibility Study on the cumulative results of each discipline studied, so that if a particular portion of the work would result in the conclusion that further work based on these results would be unwarranted for a particular alternative, the Manager shall have no obligation to continue expenditures on other Pre-Feasibility Studies related solely to such alternative.

BBB.   Completion of Pre-Feasibility Studies and Selection of Approved Alternatives. As soon as reasonably practical following completion of all Pre-Feasibility Studies required to evaluate fully the alternatives studied pursuant to Pre-Feasibility Programs, the Manager shall prepare a report summarizing all Pre-Feasibility Studies and shall submit the same to the Management Committee. Such report shall incorporate the following:

1. the results of the analyses of the alternatives and other matters evaluated in the conduct of the Pre-Feasibility Programs;

2. reasonable estimates of capital costs for the Development and start-up of the mine, mill and other processing and ancillary facilities required by the Development and Mining alternatives evaluated (based on flowsheets, piping and instrumentation diagrams, and other major engineering diagrams), which cost estimates shall include reasonable estimates of:

(xii)     capitalized pre-stripping expenditures, if an open pit or surface mine is proposed;

(xiii)    expenditures required to purchase, construct and install all machinery, equipment and other facilities and infrastructure (including contingencies) required to bring a mine into Commercial Production, including an analysis of costs of equipment or supply contracts in lieu of Development costs for each Development and Mining alternative evaluated;

34

(xiv)    expenditures required to perform all other related work required to commence Commercial Production of Products and, if applicable, process Products (including reasonable estimates of working capital requirements); and

(xv)     all other direct and indirect costs and general and administrative expenses that may be required for a proper evaluation of the Development and Mining alternatives and annual production levels evaluated. The capital cost estimates shall include a schedule of the timing of the estimated capital requirements for each alternative;

3. a reasonable estimate of the annual expenditures required for the first year of Operations after completion of the capital program described in Subsection 9.8(b) for each Development alternative evaluated, and for subsequent years of Operations, including estimates of annual production, processing, administrative, operating and maintenance expenditures, taxes (other than income taxes), working capital requirements, royalty and purchase obligations, equipment leasing or supply contract expenditures, work commitments, Environmental Compliance costs, post-Operations Environmental Compliance and Continuing Obligations funding requirements and all other anticipated costs of such Operations. This analysis shall also include an estimate of the number of employees required to conduct such Operations for each alternative;

4. a review of the nature, extent and rated capacity of the mine, machinery, equipment and other facilities preliminarily estimated to be required for the purpose of producing and marketing Products under each Development and Mining alternative analyzed;

5. an analysis (and sensitivity analyses reasonably requested by either Participant), based on various target rates of return and price assumptions requested by either Participant, of whether it is technically, environmentally, and economically feasible to place a prospective ore body or deposit within the Properties into Commercial Production for each of the Development and Mining alternatives analyzed (including a discounted cash flow rate of return investment analysis for each alternative and net present value estimate using various discount rates requested by either Participant); and

6. such other information as the Management Committee deems appropriate.

Within 60 days after delivery of the Pre-Feasibility Study summary to the Participants, a Management Committee meeting shall be convened for the purposes of reviewing the Pre-Feasibility Study summary and selecting one or more Approved Alternatives, if any.

CCC.   Programs and Budgets for Management Assessment Study. Within 30 days following the selection of an Approved Alternative, the Manager shall submit to the

35

Management Committee a Program and a Budget, which shall include necessary Operations, for the preparation of a Management Assessment Study. A Management Assessment Study may be prepared by the Manager, Feasibility Contractors, or both, or may be prepared by the Manager and audited by Feasibility Contractors, as the Management Committee determines.

DDD.  Development Programs and Budgets. Unless otherwise determined by the Management Committee, the Manager shall not submit to the Management Committee a Program and Budget including Development of the mine described in a completed Management Assessment Study until 90 days following the receipt by Manager of the Management Assessment Study. The Program and Budget, which includes Development of the mine described in the completed Management Assessment Study, shall be based on the estimated cost of Development described in the Management Assessment Study for the Approved Alternative, unless otherwise directed by the Management Committee.

EEE.   Expansion or Modification Programs and Budgets. Any Program and Budget proposed by the Manager involving Expansion or Modification shall be based on a Management Assessment Study prepared by the Manager, Feasibility Contractors, or both, or prepared by the Manager and audited by Feasibility Contractors, as the Management Committee determines. The Program and Budget, which include Expansion or Modification, shall be submitted for review and approval by the Management Committee within 90 days following receipt by the Manager of such Management Assessment Study.

FFF.    Budget Overruns; Program Changes. For Programs and Budgets adopted after completion of Barrick’s Initial Contribution, the Manager shall immediately notify the Management Committee of any material departure from an adopted Program and Budget. If the Manager exceeds an adopted Budget by more than 10% in the aggregate, then the excess over 10%, unless directly caused by an emergency or unexpected expenditure made pursuant to Section 9.13 or unless otherwise authorized or ratified by the Management Committee, shall be for the sole account of the Manager and such excess shall not be included in the calculations of the Participating Interests nor deemed a contribution under this Agreement. Budget overruns of 10% or less in the aggregate shall be borne by the Participants in proportion to their respective Participating Interests.

GGG.  Emergency or Unexpected Expenditures. In case of emergency, the Manager may take any reasonable action it deems necessary to protect life or property, to protect the Assets or to comply with Laws. The Manager may make reasonable expenditures on behalf of the Participants for unexpected events that are beyond its reasonable control and that do not result from a breach by it of its standard of care. The Manager shall promptly notify the Participants of the emergency or unexpected expenditure, and the Manager shall be reimbursed for all resulting costs by the Participants in proportion to their respective Participating Interests.

36

ARTICLE X

ACCOUNTS AND SETTLEMENTS

HHH.  Monthly Statements. After completion of Barrick’s Initial Contribution, and subject to Barrick electing to carry MGC to Commercial Production pursuant to Subsection 5.2(c) above, the Manager shall promptly submit to the Management Committee monthly statements of account reflecting in reasonable detail the charges and credits to the Business Account during the preceding month.

III.       Cash Calls. Unless MGC has elected to exercise the Carry Option, on the basis of each Program and Budget adopted by the Management Committee, the Manager shall submit prior to the last day of each month a billing for estimated cash requirements for the next month. Within 10 days after receipt of each billing, or a billing made pursuant to Section 9.12 or 12.4, each Participant shall advance its proportionate share of such cash requirements. The Manager shall record all funds received in the Business Account. All funds in excess of immediate cash requirements shall be invested by the Manager for the benefit of the Business in cash management accounts and investments selected at the discretion of the Manager, which accounts may include, but are not limited to, money market investments and money market funds.

JJJ.      Failure to Meet Cash Calls. A Participant that fails to meet cash calls in the amount and at the times specified in Section 10.2 shall be in default, and the amounts of the defaulted cash call shall bear interest from the date due at an annual rate equal to two percentage points over the Prime Rate, but in no event shall the rate of interest exceed the maximum permitted by Law. Such interest shall accrue to the benefit of and be payable to the non-defaulting Participant, but shall not be deemed as amounts contributed by the non-defaulting Participant in the event dilution occurs in accordance with Article VI. In addition to any other rights and remedies available to it by Law, the non-defaulting Participant shall have those other rights, remedies, and elections specified in Sections 10.4 and 10.5.

KKK.  Cover Payment. If a Participant defaults in making a contribution or cash call required by an adopted Program and Budget, the non-defaulting Participant may, but shall not be obligated to, advance some portion or all of the amount in default on behalf of the defaulting Participant (a ”Cover Payment”). Each and every Cover Payment shall constitute a demand loan bearing interest from the date of the advance at the rate provided in Section 10.3. If more than one Cover Payment is made, the Cover Payments shall be aggregated and the rights and remedies described herein pertaining to an individual Cover Payment shall apply to the aggregated Cover Payments. The failure to repay such loan upon demand shall be a default.

LLL.   Remedies. The Participants acknowledge that if either Participant defaults in making a contribution required by Section 5.5 or a cash call, or in repaying a loan, as required under Sections 10.2, 10.3 or 10.4, whether or not a Cover Payment is made, it will be difficult to measure the damages resulting from such default (it being hereby understood and agreed that the Participants have attempted to determine such damages in advance and determined that the calculation of such damages cannot be ascertained with reasonable certainty). Both Participants acknowledge and recognize that the damage to the non-defaulting Participant could be

37

significant. In the event of such default, as reasonable liquidated damages, the non-defaulting Participant may, with respect to any such default not cured within 90 days after notice to the defaulting Participant of such default, elect the following remedy of diluting or eliminating the defaulting Participant’s Participating Interest by giving notice to the defaulting Participant. Such election may be made with respect to each failure to meet a cash call relating to a Program and Budget, regardless of the frequency of such cash calls, provided such cash calls are made in accordance with Section 10.2.

1. The non-defaulting Participant may elect to have the defaulting Participant’s Participating Interest diluted or eliminated as follows:

(i)        For a default occurring before Payout relating to a Program and Budget covering in whole or in part Exploration, Pre-Feasibility Study or Management Assessment Study Operations, the Reduced Participant’s Participating Interest shall be recalculated by dividing: (X) the sum of (1) the value of the Reduced Participant’s Initial Contribution under Section 5.4 (c)(iii), (2) the total of all the Reduced Participant contributed under 5.5, and (3) the amount, if any, the Reduced Participant contributed to the adopted Program and Budget with respect to which the default occurred; by (Y) the sum of (1), (2) and (3) above for both Participants; and then multiplying the result by one hundred. For such a default occurring after Payout, the Reduced Participant’s Participating Interest shall be reduced in an amount equal to two times the amount by which it would have been reduced if such default had occurred before Payout. For such a default, whether occurring before or after Payout, the Recalculated Participating Interest shall then be further reduced:

(A)      for a default relating exclusively to an Exploration Program and Budget, by multiplying the Recalculated Participating Interest by 80%; or

(B)      for a default relating to a Program and Budget covering in whole or in part Pre-Feasibility Study and/or Management Assessment Study Operations, by multiplying the Recalculated Participating Interest by 60%.

The Participating Interest of the other Participant shall be increased by the amount of the reduction in the Participating Interest of the Reduced Participant, including the further reduction under Subsections 10.5(a)(i)(A) or (B).

(ii)       For a default relating to a Program and Budget covering in whole or in part Development or Mining, at the non-defaulting Participant’s election, the defaulting Participant shall be deemed to have withdrawn and to have automatically relinquished its interest in the Assets to the non-defaulting Participant; provided, however, the defaulting

38

Participant shall have the right to receive only from 10% of Net Proceeds, if any, and not from any other source, an amount equal to 75% of the defaulting Participant’s Equity Account balance at the time of such default. Upon receipt of such amount the defaulting Participant shall thereafter have no further right, title or interest in the Assets (except for MGC’s right under Subsection 6.2(a) to receive a Net Smelter Returns Royalty), and shall be relieved from any further liability to the non-defaulting Participant to the extent that such amount forms the basis for the reduction or elimination of the defaulting Participant’s Participating Interest.

(iii)      Dilution under this Subsection 10.5(a) shall be effective as of the date of the original default, and for greater certainty shall be subject to the provisions of Section 6.2. The amount of any Cover Payment under Section 10.4 and interest thereon, or any interest accrued in accordance with Section 10.3, shall be deemed to be amounts contributed by the non-defaulting Participant, and not as amounts contributed by the defaulting Participant.

(iv)      Whenever the Participating Interests are recalculated pursuant to this Subsection 10.5(a), the Equity Accounts of both Participants shall be adjusted to bear the same ratio to each other as their recalculated Participating Interests.

MMM. Audits.

1. After completion of Barrick’s Initial Contribution, within 90 days after the end of each calendar year, at the request of a Participant, an audit shall be completed by certified public accountants selected by, and independent of, the Manager. The audit shall be conducted in accordance with generally accepted auditing standards and shall cover all books and records maintained by the Manager pursuant to this Agreement, all Assets and Encumbrances, and all transactions and Operations conducted during such calendar year, including production and inventory records and all costs for which the Manager sought reimbursement under this Agreement, together with all other matters customarily included in such audits. All written exceptions to and claims upon the Manager for discrepancies disclosed by such audit shall be made not more than three months after receipt of the audit report, unless either Participant elects to conduct an independent audit pursuant to Subsection 10.6(b) which is ongoing at the end of such three month period, in which case such exceptions and claims may be made within the period provided in Subsection 10.6(b). Failure to make any such exception or claim within such period shall mean the audit is deemed to be correct and binding upon the Participants. The cost of all audits under this Subsection shall be charged to the Business Account.

39

2. Notwithstanding the annual audit conducted by certified public accountants selected by the Manager, each Participant shall have the right to have an independent audit of all Business books, records and accounts, including all charges to the Business Account. This audit shall review all issues raised by the requesting Participant, with all costs borne by the requesting Participant. The requesting Participant shall give the other Participant 30 days prior notice of such audit. Any audit conducted on behalf of either Participant shall be made during the Manager’s normal business hours and shall not interfere with Operations. A Participant shall not have the right to audit records and accounts of the Business relating to transactions or Operations more than 24 months after the calendar year during which such transactions, or transactions related to such Operations, were charged to the Business Account. All written exceptions to and claims upon the Manager for discrepancies disclosed by such audit shall be made not more than three months after completion and delivery of such audit, or they shall be deemed waived.

ARTICLE XI

DISPOSITION OF PRODUCTION

NNN.  Taking In Kind. Each Participant shall take in kind or separately dispose of its share of all Products in proportion to its Participating Interest. Any extra expenditure incurred in the taking in kind or separate disposition by either Participant of its proportionate share of Products shall be borne by such Participant. Nothing in this Agreement shall be construed as providing, directly or indirectly, for any joint or cooperative marketing or selling of Products or permitting the processing of Products owned by any third party at any processing facilities constructed by the Participants pursuant to this Agreement. The Manager shall give notice in advance of the anticipated delivery date upon which Products will be available.

OOO.  Failure of Participant to Take In Kind. If a Participant fails to take its proportionate share of Products in kind, the Manager shall have the right, but not the obligation, for a period of time consistent with the minimum needs of the industry, but not to exceed one year from the notice date described in Section 11.1, to purchase the Participant’s share for its own account or to sell such share as agent for the Participant at not less than the prevailing market price in the area. Subject to the terms of any such contracts of sale then outstanding, during any period that the Manager is purchasing or selling a Participant’s share of production, the Participant may elect by notice to the Manager to take in kind. The Manager shall be entitled to deduct from proceeds of any sale by it for the account of a Participant reasonable expenses incurred in such a sale.

PPP.    Hedging. Neither Participant shall have any obligation to account to the other Participant for, nor have any interest or right of participation in any profits or proceeds nor have any obligation to share in any losses from, futures contracts, forward sales, trading in puts, calls, options or any similar hedging, price protection or marketing mechanism employed by a

40

Participant with respect to its proportionate share of any Products produced or to be produced from the Properties.

ARTICLE XII

WITHDRAWAL AND TERMINATION

QQQ.  Termination by Expiration or Agreement. This Agreement shall terminate as expressly provided herein, unless earlier terminated by written agreement.

RRR.   Termination by Deadlock. If the Management Committee fails to adopt a Program and Budget for 12 months after the expiration of the latest adopted Program and Budget, either Participant may elect to terminate the Business by giving 90 days notice of termination to the other Participant.

SSS.    Withdrawal. A Participant may elect to withdraw from the Business by (i) in the case of Barrick, failing to make the Exploration Expenditures as required by Subsection 5.2, or (ii) giving notice to the other Participant of the effective date of withdrawal, which shall be the later of the end of the then current Program Period or 30 days after the date of the notice. Upon such withdrawal, the Business shall terminate, and the withdrawing Participant shall be deemed to have transferred to the remaining Participant all of its Participating Interest, including all of its interest in the Assets, without cost and free and clear of all Encumbrances arising by, through or under such withdrawing Participant, except those described in Exhibit A and those to which both Participants have agreed. The withdrawing Participant shall execute and deliver all instruments as may be necessary in the reasonable judgment of the other Participant to effect the transfer of its interests in the Assets to the other Participant. If within a 60 day period both Participants elect to withdraw, then the Business shall instead be deemed to have been terminated by the consent of the Participants pursuant to Section 12.1.

TTT.   Continuing Obligations and Environmental Liabilities. On termination of the Business under Sections 12.1, 12.2 or 12.3, each Participant shall remain liable for its respective share of liabilities to third persons (whether such arises before or after such withdrawal), including Environmental Liabilities and Continuing Obligations.

Barrick and MGC and their respective Affiliates for their separate account shall be free to acquire lands and interests in lands outside the Area of Interest and to locate mining claims outside the Area of Interest. Failure of any Affiliate of either Participant to comply with this Article XIII shall be a breach by such Participant of this Agreement.

ZZZ.   Acquisitions During Exploration Period. During the Exploration Period, Barrick shall promptly notify MGC of any acquisitions by Barrick of any interests in real property wholly or partially within the Area of Interest, and all such interests shall automatically

42

become part of the Properties and subject to this Agreement. Barrick may include the costs of such acquisitions as Exploration Expenditures.

AAAA.           Notice to Non-Acquiring Participant. If the Participants have entered into a joint venture, than the remaining provisions of this Article XIII shall apply. Within 15 days after the acquisition or proposed acquisition, as the case may be, of any interest or the right to acquire any interest in real property or water rights wholly or partially within the Area of Interest (except real property acquired by the Manager pursuant to a Program), the Acquiring Participant shall notify the other Participant of such acquisition by it or its Affiliate; provided further that if the acquisition of any interest or right to acquire any interest pertains to real property or water rights partially within the Area of Interest, then all such real property (i.e., the part within the Area of Interest and the part outside the Area of Interest) shall be subject to this Article XIII. The Acquiring Participant’s notice shall describe in detail the acquisition, the acquiring party if that party is an Affiliate, the lands and minerals covered thereby, any water rights related thereto, the cost thereof, and the reasons why the Acquiring Participant believes that the acquisition (or proposed acquisition) of the interest is in the best interests of the Participants under this Agreement. In addition to such notice, the Acquiring Participant shall make any and all information concerning the relevant interest available for inspection by the other Participant.

BBBB.Option Exercised. Within 30 days after receiving the Acquiring Participant’s notice, the other Participant may notify the Acquiring Participant of its election to accept a proportionate interest in the acquired interest equal to its Participating Interest.

The acquired interests shall become a part of the Properties for all purposes of this Agreement immediately upon such notice. The other Participant shall promptly pay to the Acquiring Participant its proportionate share of the latter’s actual out of pocket acquisition costs.

CCCC.Option Not Exercised. If the other Participant does not give such notice within the 30-day period set forth in Section 13.4, it shall have no interest in the acquired interests, and the acquired interests shall not be a part of the Assets or continue to be subject to this Agreement.

DDDD.           Water Rights. If either Participant acquires any water rights for the use on or for the benefit of the Properties, that Participant shall contribute those acquired water rights for the benefit of the Business, and shall contribute those water rights to the Business, or if such water rights are acquired by Barrick and Barrick does not complete its Initial Contribution, Barrick shall convey such water rights to MGC.

ARTICLE XIV

ABANDONMENT AND SURRENDER OF PROPERTIES

Either Participant may request the Management Committee to authorize the Manager to surrender or abandon part or all of the Properties. If the Management Committee does not authorize such surrender or abandonment, or authorizes any such surrender or abandonment over the objection of either Participant, the Participant that desires to surrender or abandon shall assign to the objecting Participant, by special warranty deed and without cost to the objecting Participant, all of the abandoning Participant’s interest in the Properties sought to be abandoned or surrendered, free and clear of all Encumbrances created by, through or under the abandoning Participant other than those to which both Participants have agreed. Upon the assignment, such properties shall cease to be part of the Properties. The Participant that desires to abandon or surrender shall remain liable for its share (determined by its Participating Interest as of the date of such abandonment, after first taking into account any reduction, readjustment and restoration of Participating Interest under Sections 6.2, 9.5, 9.6 or 10.5) of any liability with respect to such Properties, including, without limitation, Continuing Obligations, Environmental Liabilities and Environmental Compliance, whether accruing before or after such abandonment, arising out of activities prior to the Effective Date and out of Operations conducted prior to the date of such abandonment, regardless of when any funds may be expended to satisfy such liability.

EEEE. General. A Participant shall have the right to Transfer to a third party an interest in its Participating Interest, including an interest in this Agreement or the Assets, solely as provided in this Article XV.

1. Neither Participant shall Transfer any interest in this Agreement or the Assets (including, but not limited to, any royalty, profits, or other interest in the Products) except in conjunction with the Transfer of part or all of its Participating Interest;

2. No transferee of all or any part of a Participant’s Participating Interest shall have the rights of a Participant unless and until the transferring Participant has provided to the other Participant notice of the Transfer, and, except as provided in Subsections 15.2(f) and 15.2(g), the transferee, as of the effective date of the Transfer, has committed in writing to assume and be bound by this Agreement to the same extent as the transferring Participant;

44

3. Neither Participant, without the consent of the other Participant, shall make a Transfer that shall violate any Law, or result in the cancellation of any permits, licenses, or other similar authorization;

4. No Transfer permitted by this Article XV shall relieve the transferring Participant of its share of any liability, whether accruing before or after such Transfer, which arises out of Operations conducted prior to such Transfer or exists on the Effective Date;

5. In the event of a Transfer of less than all of a Participating Interest, the transferring Participant and its transferee shall act and be treated as one Participant; provided however, that in order for such Transfer to be effective, the transferring Participant and its transferee must first:

(i)        agree, as between themselves, that one of them is authorized to act as the sole agent (“Agent”) on their behalf with respect to all matters pertaining to this Agreement and the Business; and

(ii)       notify the other Participant of the designation of the Agent, and in such notice warrant and represent to other Participant that:

(A)      the Agent has the sole authority to act on behalf of, and to bind, the transferring Participant and its transferee with respect to all matters pertaining to this Agreement and the Business;

(B)      the other Participant may rely on all decisions of, notices and other communications from, and failures to respond by, the Agent, as if given (or not given) by the transferring Participant and its transferee; and

(C)      all decisions of, notices and other communications from, and failures to respond by, the other Participant to the Agent shall be deemed to have been given (or not given) to the transferring Participant and its transferee.

The transferring Participant and its transferee may change the Agent (but such replacement must be one of them) by giving notice to the other Participant, which notice must conform to Subsection 15.2(e)(ii).

6. If the Transfer is the grant of an Encumbrance in a Participating Interest to secure a loan or other indebtedness of either Participant in a bona fide transaction, other than a transaction approved unanimously by the Management Committee or Project Financing approved by the Management Committee, such Encumbrance shall be granted only in connection with such Participant’s financing payment or performance of that Participant’s obligations under this Agreement and shall be

45

subject to the terms of this Agreement and the rights and interests of the other Participant hereunder (including without limitation under Section 6.7). Any such Encumbrance shall be further subject to the condition that the holder of such Encumbrance (“Chargee”) first enter into a written agreement with the other Participant in form satisfactory to the other Participant, acting reasonably, binding upon the Chargee, to the effect that:

(iii)      the Chargee shall not enter into possession or institute any proceedings for foreclosure or partition of the encumbering Participant’s Participating Interest and that such Encumbrance shall be subject to the provisions of this Agreement;

(iv)      the Chargee’s remedies under the Encumbrance shall be limited to the sale of the whole (but only of the whole) of the encumbering Participant’s Participating Interest to the other Participant, or, failing such a sale, at a public auction to be held at least 15 days after prior notice to the other Participant, such sale to be subject to the purchaser entering into a written agreement with the other Participant whereby such purchaser assumes all obligations of the encumbering Participant under the terms of this Agreement. The price of any preemptive sale to the other Participant shall be the remaining principal amount of the loan plus accrued interest and related expenses, and such preemptive sale shall occur within 60 days of the Chargee’s notice to the other Participant of its intent to sell the encumbering Participant’s Participating Interest. Failure of a sale to the other Participant to close by the end of such period, unless failure is caused by the encumbering Participant or by the Chargee, shall permit the Chargee to sell the encumbering Participant’s Participating Interest at a public sale; and

(v)       the charge shall be subordinate to any then-existing debt, including Project Financing previously approved by the Management Committee, encumbering the transferring Participant’s Participating Interest;

7. If a sale or other commitment or disposition of Products or proceeds from the sale of Products by either Participant upon distribution to it pursuant to Article XI creates in a third party a security interest by Encumbrance in Products or proceeds therefrom prior to such distribution, such sales, commitment or disposition shall be subject to the terms and conditions of this Agreement including, without limitation, Section 6.7.

GGGG.           Preemptive Right. Any Transfer by either Participant under Section 15.1 and any Transfer by an Affiliate of Control of either Participant shall be subject to a preemptive right of the other Participant to the extent provided in Exhibit G. Failure of a Participant’s

46

Affiliate to comply with this Article XV and Exhibit G shall be a breach by such Participant of this Agreement.

ARTICLE XVI

47

before and after the termination of the Business, all Business Information may be used by either Participant for any purpose, whether or not competitive with the Business, without consulting with, or obligation to, the other Participant. Except as provided in Sections 17.3 and 17.4, or with the prior written consent of the other Participant, each Participant shall keep confidential and not disclose to any third party or the public any portion of the Business Information that constitutes Confidential Information.

KKKK.           Participant Information. In performing its obligations under this Agreement, neither Participant shall be obligated to disclose any Participant Information. If a Participant elects to disclose Participant Information in performing its obligations under this Agreement, such Participant Information, together with all improvements, enhancements, refinements and incremental additions to such Participant Information that are developed, conceived, originated or obtained by either Participant in performing its obligations under this Agreement (“Enhancements”), shall be owned exclusively by the Participant that originally developed, conceived, originated or obtained such Participant Information. Each Participant may use and enjoy the benefits of such Participant Information and Enhancements in the conduct of the Business hereunder, but the Participant that did not originally develop, conceive, originate or obtain such Participant Information may not use such Participant Information and Enhancements for any other purpose. Except as provided in Section 17.4, or with the prior written consent of the other Participant, which consent may be withheld in such Participant’s sole discretion, each Participant shall keep confidential and not disclose to any third party or the public any portion of Participant Information and Enhancements owned by the other Participant that constitutes Confidential Information.

LLLL. Permitted Disclosure of Confidential Business Information. Either Participant may disclose Business Information that is Confidential Information:

1. to a Participant’s officers, directors, partners, members, employees, Affiliates, shareholders, agents, attorneys, accountants, consultants, contractors, subcontractors or advisors, for the sole purpose of such Participant’s performance of its obligations under this Agreement;

2. to any party to whom the disclosing Participant contemplates a Transfer of all or any part of its Participating Interest, for the sole purpose of evaluating the proposed Transfer;

3. to any actual or potential lender, underwriter or investor for the sole purpose of evaluating whether to make a loan to or investment in the disclosing Participant (or any of its Affiliates); or

4. to a third party with whom the disclosing Participant (or any of its Affiliates) contemplates any independent business activity or operation.

The Participant disclosing Confidential Information pursuant to this Section 17.3, shall disclose such Confidential Information to only those parties who have a bona fide need to have access to

48

such Confidential Information for the purpose for which disclosure to such parties is permitted under this Section 17.3 and who have agreed in writing supplied to, and enforceable by, the other Participant to protect the Confidential Information from further disclosure, to use such Confidential Information solely for such purpose and to otherwise be bound by the provisions of this Article XVII. Such writing shall not preclude parties described in Subsection 17.3(b) from discussing and completing a Transfer with the other Participant. The Participant disclosing Confidential Information shall be responsible and liable for any use or disclosure of the Confidential Information by such parties in violation of this Agreement and such other writing.

MMMM.        Disclosure Required By Law.

Prior to any disclosure of Confidential Information under this Section 17.4, the disclosing Participant shall give the other Participant at least 10 days prior written notice (unless less time is permitted by such rules, regulations or proceeding) and, in making such disclosure, the disclosing Participant shall disclose only that portion of Confidential Information required to be disclosed and shall take all reasonable steps to preserve the confidentiality thereof, including, without limitation, obtaining protective orders and supporting the other Participant in intervention in any such proceeding.

NNNN.           Public Announcements. Prior to making or issuing any press release or other public announcement or disclosure of Business Information that is not Confidential Information, a Participant (or any of its Affiliates) shall first consult with the other Participant as to the content and timing of such announcement or disclosure, unless in the good faith judgment of such Participant, there is not sufficient time to consult with the other Participant before such announcement or disclosure must be made under applicable Laws; but in such event, the disclosing Participant shall notify the other Participant, as soon as possible, of the pendency of such announcement or disclosure, and it shall notify the other Participant before such announcement or disclosure is made if at all reasonably possible. Any press release or other public announcement or disclosure to be issued by either Participant (or any of its Affiliates) relating to this Business shall also identify the other Participant. Notwithstanding any of the provisions of the Article XVII to the contrary, the Participants agree that MGC (or any Affiliate of MGC) may issue quarterly press releases based on the information provided by Barrick to MGC in the quarterly reports referred to in Subsection 5.1(a)(ii), in accordance with the provisions of this Section 17.5.

4. the Discloser shall be entitled to access to all pertinent information related to the Assets as necessary for it to prepare the Technical Report; and

5. The information generated by a Participant concerning the Assets and Properties may contain estimates and forecasts that are interpretive and/or speculative in nature. The accuracy of such estimates and forecasts generated by one Participant is in no manner warranted to the other Participant. Instead, each Discloser shall rely only on its own forecasts, interpretations, and estimates for its business planning and reporting purposes and may release such forecasts, interpretations and estimates only so long as they are clearly identified as having been prepared by the Discloser.

It is the intent of the Participants that neither of them shall lose or profit by reason of the designation of one of them to exercise the duties and responsibilities of the Manager. The Participants shall meet and in good faith endeavor to agree upon changes deemed necessary to correct any unfairness or inequity. In the event of a conflict between the provisions of these Accounting Procedures and those of the Agreement, the provisions of the Agreement shall control.

The Manager shall maintain detailed and comprehensive cost accounting records in accordance with these Accounting Procedures, including general ledgers, supporting and subsidiary journals, invoices, checks and other customary documentation, sufficient to provide a record of revenues and expenditures and periodic statements of financial position and the results of Operations for managerial, tax, regulatory or other financial, regulatory, or legal reporting purposes related to the Business. Such records shall be retained for the duration of the period allowed the Participants for audit or the period necessary to comply with tax or other regulatory requirements. The records shall reflect all obligations, advances and credits of the Participants.

All written exceptions to and claims upon the Manager for incorrect charges, billings or statements shall be made upon the Manager within such 24 month period.

Whenever Material is not readily obtainable at published or listed prices because of national emergencies, strikes or other unusual circumstances over which the Manager has no control, the Manager may charge the Business Account for the required Material on the basis of the Manager’s direct cost and expenses incurred in procuring such Material and making it suitable for use. The Manager shall give written notice of the proposed charge to the Participants prior to the time when such charge is to be billed, whereupon either Participant shall have the right, by notifying the Manager within 10 days of the delivery of the notice from the Manager, to furnish at the usual receiving point all or part of its share of Material suitable for use and acceptable to the Manager.

(b) In the case of Products (including refined metals) that are not Refined Precious Metals and which are sold by the remaining Participant, the gross amount actually received by the remaining Participant from the purchaser for the Products so sold, less the deductions as provided in Paragraph 1(d). If the purchaser of any such Products is an Affiliate of the seller, the Products will be valued at fair market value. If the parties fail to agree on such fair market value, the matter shall be resolved as provided in Article XVI of the Agreement.

(c) “Deemed Sales Price” means: In the case of gold, the average of the London PM fixings in U.S. Dollars for refined gold (as shown in the column of the Wall Street Journal entitled “Cash Prices” under the sub-entry entitled “Precious Metals”) for each trading day during the calendar month in which the final settlement date with the refinery falls, such date to be evidenced by the refinery metal return statements and, for any subsequent adjustment, for the calendar month in which such adjustment is made. In the case of silver, the average of the Handy & Harmon base price for silver in U.S. Dollars (as shown in the column of the Wall Street Journal entitled “Cash Prices” under the sub-entry entitled “Precious Metals”) for each trading day during the calendar month in which the final settlement date with the refinery falls, such date to be evidenced by the refinery metal return statements and, for any subsequent adjustment, for the calendar month in which such adjustment is made. If either of such fixings or prices are not available for any reason for more than half of the trading days in the relevant month, or are
