Cortez Joint Venture at the time of Closing (provided such inventory is not required to be distributed to Seller pursuant to the Joint Venture Agreement), and the net book value, as determined using the books and records of the Cortez Joint Venture, of any other tangible assets not considered an interest in the minerals in place. All remaining Tax Purchase Price shall be treated as a lease bonus paid for the transfer of Seller’s interests in minerals in place subject to the reserved Royalty described in Section 2.3. The amount treated as a lease bonus shall be allocated, as the Purchaser shall determine in the exercise of its reasonable discretion, between fee or leased properties (including patented claims) and unpatented claims in which Seller has an economic interest in the minerals in place. The allocation of the Tax Purchase Price to tangible property and lease bonus payment shall be set forth on the allocation schedule attached hereto as Exhibit C (the “Allocation Schedule”) and the allocation and characterization set forth in this paragraph shall be used by Purchaser and Seller for all applicable tax purposes and in all filings, declarations and reports with the IRS in respect thereof. Both Seller and Purchaser agree to act reasonably and in good faith to complete the Allocation Schedule by February 29, 2008.

2.5 Bonus Royalty. In addition to the Production Royalty, Purchaser shall pay the Seller a one time lump sum bonus royalty of Fifty Million Dollars ($50,000,00.00), which shall be paid, if at all, within thirty (30) days after the first date Purchaser and its Affiliates report, either publicly or pursuant to the reports to Seller contemplated by the following sentence, that there has been a cumulative addition to the “Total Gold Resource,” as defined below, of 12 million contained ounces of gold in excess of the 17.8 million contained ounces of Total Gold Resource reported on December 31, 2007, as reduced from time to time by the depletion of such Total Gold Resource from cumulative gold production from and after January 1, 2008. As used in this Section, the term “Total Gold Resource” means the proven and probable reserve and measured, indicated and inferred gold resources with respect to the Property (as defined in the Royalty Deed) (in its entirety and not just with respect to the 40% undivided interest of Purchaser). On or before each February 1 after the date of the Royalty Deed and until such time as the Bonus Royalty is paid, Purchaser and its Affiliates shall furnish to Seller a written report in reasonable detail, including the method and components of the calculation, of the Total Gold Resource within the Property, and the calculation of the addition and depletion of the same described above. The Total Gold Resource shall be determined in accordance with the applicable requirements of Canadian National Instrument 43-101 and the related standards of the Canadian Institute of Mining, Metallurgy and Petroleum. Purchaser and Seller agree to treat the Bonus Royalty described above as a contingent lease bonus eligible for open transaction treatment for all applicable federal, state and local income tax purposes. When and if paid, such lease bonus shall be allocated, as the Purchaser shall determine in the exercise of its reasonable discretion, between fee or leased properties (including patented claims) and unpatented claims in which Seller has an economic interest in the minerals in place, such determination to be made in the manner described in Exhibit C.

Purchaser agrees that for purposes of the Joint Venture Agreement, Seller shall not be deemed in default or subject to reduction of its Participating Interest as a result of Purchaser making such payments on behalf of Seller.

5.3 Rebalancing. If Closing does not occur, then within ninety (90) days of the date of termination of this Agreement or five (5) days after any rebalancing amount is finally determined under Section 5.4 (whichever is the later), the Parties shall reverse the economic effect of Section 5.2 by making a payment (the “Rebalancing Payment”) as follows:

(a) Purchaser shall pay to Seller a Rebalancing Payment equal to the excess, if any, of: (i) the value (as shown on the Venture’s books) of Seller’s share of Products taken and sold by Purchaser under Section 5.2(a) above; over (ii) the sum of (A) the payments made by Purchaser under Section 5.2(b) above on behalf of Seller, plus (B) any Tax (whether direct or indirect), excluding all Taxes based on income, payable by Purchaser on Product taken under Section 5.2(a); or

(b) Seller shall pay to Purchaser a Rebalancing Payment equal to the excess, if any, of: (i) the sum of (A) the payments made by Purchaser under Section 5.2(b) above on behalf of Seller, plus (B) any Tax (whether direct or indirect), excluding all Taxes based on income, payable by Purchaser on Product taken under Section 5.2(a) by Purchaser under Section 5.2(a); over (ii) the value (as shown on the Venture’s books) of Seller’s share of Products taken and sold by Purchaser under Section 5.2(a) above.

Purchaser must promptly provide Seller with: (i) notice of all payments due by Seller in accordance with its obligation under the Joint Venture Agreement (which under Section 5.2(b) are to be paid when due by Purchaser on Seller’s behalf during the Post-Effective Date Period); and (ii) full and complete details of the value of Seller’s share of Product during the Post-Effective Date Period taken by Purchaser in accordance with Section 5.2(a); and (iii) any other information reasonably requested by Seller to monitor compliance with this Section 5.3. In the event Closing occurs, no Rebalancing Payment shall be payable by either Party.

5.4 Calculation of the Rebalancing Amount and Dispute Resolution.

(a) For the purposes of Section 5.3, Purchaser must prepare and provide Seller with a draft calculation (in writing) showing Purchaser’s calculation of the Rebalancing Payment due under Section 5.3 (“Draft Calculation”) no later than thirty (30) days after the date of termination of this Agreement. Purchaser must ensure that Seller and its advisers are given full access to the working papers and other supporting material and information that Seller and its advisers reasonably require to verify the Draft Calculation.

(b) If Seller objects to the Draft Calculation by written notice given to Purchaser within ten (10) days of being provided with the Draft Calculation under Section 5.4(a), Purchaser and Seller must enter into good faith negotiations and use all reasonable efforts to resolve the dispute. If Seller has accepted the Draft Calculation or has not objected to it within the ten (10) day period referred to above, then the Draft Calculation will be deemed to be the final calculation of the Rebalancing Payment payable under Section 5.3, which will be conclusive, final and binding on the Parties.

(c) If Seller objects to any matter in the Draft Calculation in accordance with Section 5.4(b) above and Purchaser and Seller cannot resolve the objection within fifteen (15) days of the date that Seller notifies Purchaser in writing of an objection to the Draft Calculation, then the matter will be referred for resolution to an independent international accounting firm agreed upon by both Purchaser and Seller within a further seven (7) days. If within this period, the Parties cannot agree on the identity of that independent international accounting firm, either Purchaser or Seller may request that a court of competent jurisdiction designate and appoint an independent person to determine the dispute. The person agreed or nominated under this subsection will be the “Expert” for the purposes of this clause. The Purchaser and Seller must instruct the Expert to: (i) decide the procedures to be followed in order to resolve the dispute; (ii) decide within the shortest practicable time the matters of disagreement; and (iii) apply United States generally accepted accounting principles and other professional accounting reporting requirements issued by the joint accounting bodies to determine the Rebalancing Payment payable under Section 5.3.

(d) Purchaser must provide, and must ensure that Purchaser’s accountants provide, all information and assistance that the Expert reasonably requests for the purpose of resolving the dispute. The Expert will act as expert, not as an

arbitrator in determining the dispute. The determination of the Expert will be final, conclusive and binding, except in the case of manifest error. The cost of the Expert must be shared equally between Parties.

5.5 Releases of Claims. At the Closing, Seller shall deliver a release (the “Seller’s Release”), which Seller’s Release shall be in the form attached hereto as Exhibit D, releasing BCI, all predecessors in interest, the Venture, and Purchaser and Purchaser’s Affiliates from all liabilities or Claims of Seller and its Affiliates against BCI, the Manager, all predecessors in interest, the Venture and Purchaser or Purchaser’s Affiliates related to the Venture.

Seller agrees to indemnify, defend and hold Purchaser and its Affiliates, and each of its and their officers, directors, and employees (together with Purchaser, “Purchaser Indemnitees”) harmless from and against any and all liabilities, damages, obligations, claims and expenses, including, without limitation, reasonable costs of investigation and reasonable defense and attorneys’ fees (collectively “Losses”) that a Purchaser Indemnitee sustains or becomes subject to as a result of

(a) the breach of any of the warranties, representations, covenants or agreements of Seller set forth in this Agreement or in any operative document delivered pursuant to this Agreement;

(b) any and all matters as to which Seller remains liable under this Agreement (including the Schedules and Exhibits hereto) or any other agreement delivered pursuant to the terms of this Agreement; and

(c) any and all actions, suits, proceedings, demands, assessments, judgments, damages, awards, costs and expenses (including third-party fees and expenses) incident to any of the foregoing or incurred in connection with the enforcement of the rights of any Purchaser Indemnitee with respect to the foregoing.

Purchaser agrees to indemnify, defend and hold Seller and its Affiliates, and each of its and their officers, directors and employees (together with Seller, “Seller Indemnitees”) harmless from and against all Losses that a Seller Indemnitee sustains or becomes subject to arising out of or in connection with:

(a) the Assumed Liabilities (including any failure by Purchaser to pay, perform or otherwise discharge any of the Assumed Liabilities in accordance with their terms), whether such Assumed Liabilities are known or unknown, accrued, absolute, contingent, determined, determinable or otherwise, and whether such Assumed Liabilities relate to or arise from operations, events, occurrences, actions, omissions, facts, circumstances or matters occurring, existing or asserted, before, at or after the date of the Closing (but excluding items for which a Purchaser Indemnitee is entitled to indemnification pursuant to Section 9.1);

(b) the breach of any of the warranties, representations, covenants or agreements of Purchaser set forth in this Agreement or in any operative documents delivered pursuant to this Agreement; and

9.3 Third Party Claim. Upon receipt by any person seeking to be indemnified pursuant to this Article 9 (the “Indemnitee”) of notice of any legal proceedings, (each a “Claim”) against it which has or is expected to give rise to a claim for Losses, the Indemnitee shall give prompt written notice thereof (which shall be within ten (10) days after receipt by the Indemnitee of such Claim) to the person from which it seeks to be indemnified (the “Indemnitor”), indicating the nature of such Claim and the basis therefor; provided, however, that any delay or failure by the Indemnitee to give notice to the Indemnitor shall relieve the Indemnitor of its obligations hereunder only to the extent, if at all, that it is materially prejudiced by reason of such delay or failure. The Indemnitor shall have thirty (30) days after receipt of the Indemnitee’s notice to elect, at its option, to assume the defense of, at its own expense and by its own counsel reasonably acceptable to the Indemnitee, any such Claim. If the Indemnitor shall undertake to compromise or defend any such Claim, it shall promptly notify the Indemnitee of its intention to do so. Notwithstanding an election by the Indemnitor to assume the defense of such Claim, (i) the Indemnitee shall have the right to employ at its cost separate counsel and to participate in the defense of such Claim, and (ii) the Indemnitee shall have the right at any time after the Indemnitor assumes the defense of such Claim to assume the defense of such Claim if the Indemnitor subsequently determines that it does not believe the Claim is one for which the Indemnitee is entitled to indemnification, compensation or reimbursement under this Article 9 and requests that the Indemnitee assume the defense of such Claim (in which case the Indemnitee may retain the legal counsel previously retained by the Indemnitor to assist in the defense of such Claim). The Indemnitee and Indemnitor and their counsel shall cooperate fully in the compromise or defense of any Claim subject to this Article 9 and keep one another informed of all developments relating to any such Claims, and provide copies of all relevant correspondence and documentation relating thereto. If an Indemnitor receiving a notice of Claim does not elect to defend such Claim within the thirty (30) day period referred to above, the Indemnitee shall have the right, in addition to any other right or remedy it may have hereunder, at the Indemnitor’s expense, to defend such Claim. The Indemnitee’s defense of, or participation in the defense of, any such Claim shall not in any way diminish or lessen the obligations of the Indemnitor under this Article 9. In no event may an Indemnitor or an Indemnitee settle or compromise any Claim without the consent of the other (which consent will not be unreasonably withheld, conditioned or delayed).

9.4 Indemnity Exclusive Remedy. The indemnity in this Article 9 shall be the exclusive remedy for any misrepresentation or breach of warranty or breach of any covenant or agreement in this Agreement. Notwithstanding anything to the contrary in this Agreement, Purchaser and its successors and assigns understand and agree that the indemnification obligations of Seller under Article 9 of this Agreement shall constitute the sole and exclusive remedy of Purchaser with respect to any matters or claims arising under Environmental Laws.

The representations and warranties of the Parties made herein or in any other documentation delivered pursuant to this Agreement and the covenants and agreements to be performed on or prior to the Closing Date shall survive the Closing Date, and shall not merge with or be extinguished by delivery of any of the assignment and transfer documents contemplated by this Agreement. The absence or limitation of representations and warranties in such documents shall not diminish in any way the representations and warranties of the Parties in this Agreement.

9.6 Parent or Affiliate Guaranties. The Parties agree that each of them will cause that a Guaranty shall be executed and delivered, at the sole election of the Seller as to which parties shall deliver such Guaranties, (a) in the case of Seller, in the form attached hereto as Exhibit N (the “Seller’s Guaranty”), by either Rio Tinto PLC or Kennecott Holdings Corporation, and (b) in the case of Purchaser, in the form attached hereto as Exhibit O (the “Purchaser’s Guaranty”), by Barrick Gold Corporation, if Seller elects that Rio Tinto PLC shall deliver such Guaranty, or ABX Financeco, Inc., if Seller elects that Kennecott Holdings Corporation shall deliver such Guaranty.

13. MISCELLANEOUS MATTERS.

13.1 Succession. Purchaser may assign all or any part of its interest in this Agreement to any of its Affiliates, provided, however, that Purchaser shall continue to be bound by the terms and conditions of this Agreement unless Seller agrees otherwise. Otherwise, except as provided in Section 13.2 below, before the Closing, neither Party shall have the right to assign all or any part of its interest in this Agreement without the prior written consent of the other Party. This Agreement shall be binding upon and shall inure to the benefit of the Parties, their heirs, successors and permitted assigns.

13.2 Qualified Intermediary Assignment. Notwithstanding any provision in this Agreement, to facilitate a “like-kind” exchange under Section 1031 of the Internal Revenue Code of 1986, as amended (the “Code”), Seller may assign all or any portion of its rights (but not obligations) under this Agreement with respect to sale of the machinery and equipment, including the Purchase Price allocated thereto in Exhibit C, to a qualified intermediary, an exchange accommodation title holder or one or more single member limited liability companies that are owned by any of the foregoing persons (each a “Qualified Intermediary”) in accordance with the provisions of Section 1031 of the Code, the Treasury Regulations thereunder, and IRS Revenue Procedure 2000-37. Purchaser shall cooperate with the Seller as may be reasonably necessary in connection with such assignment and the deferred tax-free exchange to be accomplished in connection therewith, including acknowledging the execution of a written agreement between Seller and the Qualified Intermediary, subject to reimbursement by Seller for actual out-of-pocket expenses incurred by Purchaser as a

result of a request by Seller in connection with the foregoing; and provided Seller does not incur additional obligations or liability as a result of such cooperation or actions. No assignment of rights under this Agreement, under the foregoing provision, shall effect a release of such party from obligations under this Agreement or impose any additional obligation or liability on the other party.

13.3 Amendment. This Agreement may only be amended by an instrument in writing executed by Purchaser and Seller.

13.4 Law of Agreement; Exclusive Jurisdiction. This Agreement shall be interpreted and construed under and in accordance with the law of Nevada applicable to contracts made and to be performed wholly within the State of Nevada, without giving effect to any of the conflicts of law provisions thereunder. Any proceeding brought relating to this Agreement shall be brought only in the applicable state and federal courts located in Reno, Nevada and venue shall only be proper in such courts. Each Party hereto agrees and covenants that it will not raise any claim of inconvenient forum or any similar objection to jurisdiction to such courts.

13.5 Waiver. Any of the terms or conditions of this Agreement may be waived at any time and from time to time, in writing, by such Parties as are entitled to the benefit of such terms or conditions; provided, however, that except as otherwise specifically provided in this Agreement, no failure or delay on the part of either Party in exercising any of their respective rights hereunder upon any failure by the other Party to perform or observe any condition, covenant or provision herein contained shall operate as a waiver thereof, nor shall any single or partial exercise of any of such rights preclude any other or further exercise thereof or the exercise of any other right hereunder. No waiver or release of any of the terms, conditions or provisions of this Agreement shall be valid or asserted or relied upon by either Party hereto or offered in any judicial proceeding or otherwise, unless the same is in writing, duly executed by both Parties.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given (i) when delivered personally, (ii) when received by the addressee, if sent by Federal Express or other generally recognizable express delivery service, or (iii) on the day of transmittal if given by electronic mail (“email”) prior to 5:00 p.m. EST or EDT as may be applicable, on a business day, and on the next following business day if given by email after 5:00 p.m. EST or EDT, as may be applicable, on a business day and on the next business day if given on any day other than a business day at the following addresses (or to such other address for a Party as shall be specified by like notice; provided that notices of a change of address shall be effective only upon receipt thereof).

WHEREAS, Seller owns a forty percent (40%) Participating Interest in the Cortez Joint Venture (the “Venture”) and a corresponding forty percent (40%) undivided interest as a tenant-in-common in all of the Assets of the Venture.

WHEREAS, effective as of the date of this Assumption, Purchaser is purchasing Seller’s 40% Participating Interest in the Cortez Joint Venture, together with all of Seller’s right, title and interest in the Venture’s Assets (other than mineral interests held by Seller that were offered to the Venture pursuant to the terms of the Joint Venture Agreement and rejected by the Venture), and all other related property rights and assets of Seller located within the Area of Interest (excluding the interests of Seller under the Royalty Deed and the Production Royalty reserved under Section 2.3 of the Purchase Agreement) (the “Purchased Assets”), pursuant to the terms of that certain Purchase Agreement, by and between Purchaser and Seller, dated as of February 21, 2008 (the “Purchase Agreement”).

WHEREAS, pursuant to the provisions of the Purchase Agreement, Purchaser has agreed to assume the obligations of Seller related to the Cortez Mine, the Joint Venture Agreement and the Purchased Assets, as more fully set forth herein.

RIO TINTO PRODUCTION ROYALTY DEED

FOR GOOD AND VALUABLE CONSIDERATION, the receipt and sufficiency of which are hereby expressly acknowledged, by this Rio Tinto Production Royalty Deed (the “Rio Tinto Royalty Deed”), Kennecott Explorations (Australia) Ltd., a Delaware corporation (hereinafter referred to as “Royalty Holder”), hereby reserves to itself, its successors and assigns, from the transfers of interest to Barrick Gold Finance, Inc., a Delaware corporation (which, together with its transferees, successors and assigns, is hereinafter referred to as “Barrick”) made pursuant to the Purchase Agreement (as defined below), and certain deeds, assignments and assumptions pursuant to the Purchase Agreement, each of even date herewith, a certain “Production Royalty” as hereinafter defined and computed, with respect to the “Property” as defined below. The parties hereto are referred to individually as a “Party” and collectively as the “Parties”.

The Royalties described in this Rio Tinto Royalty Deed are reserved pursuant to that certain Purchase Agreement, dated February 21, 2008 (the “Purchase Agreement”) by which the Royalty Holder transferred all its rights, titles and interests in the Cortez Joint Venture, as defined in the Purchase Agreement, including its undivided 40% participating interest, other than the Royalty herein described and is subject to the terms and conditions of the Purchase Agreement. The Royalty herein applies to all production of Refined Gold and Refined Silver for the account of Barrick from the Property. Accordingly, there is reserved by Royalty Holder from the conveyance of Royalty Holder’s 40% undivided interest as a tenant in common in the Property made in this Rio Tinto Royalty Deed a Production Royalty in favor of and payable to Royalty Holder as follows.

1. Definition of Production Royalty. The production royalty means the royalty reserved by Royalty Holder pursuant to this Rio Tinto Royalty Deed, out of the 40% undivided tenancy in common interest transferred to Barrick pursuant to the Purchase Agreement, which shall be a percentage of the Returns realized with respect to Refined Gold and Refined Silver delivered with respect to such 40% undivided tenancy in

common interest from and after the Commencement Date. The percentages of such royalty shall be determined upon Returns realized from Refined Gold and Refined Silver in accordance with the following schedule:


Monthly Average Gold Price
for Applicable Month	Percentage Royalty
Less than $400		0	%
$400 and up to but not including $500		0.5	%
$500 and up to but not including $600		1.0	%
$600 and up to but not including $700		1.5	%
$700 and up to but not including $800		2.0	%
$800 and up to but not including $900		2.5	%
Greater than $900		3.0	%

As an example of the foregoing, if 100 ounces of Refined Gold are delivered from a refinery from all operations on the Property (regardless of ownership), and if the monthly average gold price is then $1000 per ounce, then the Production Royalty payable under this Rio Tinto Royalty Deed (without taking into account any Allowable Deductions), would be 3% of the product of 40 ounces of Refined Gold attributed to Barrick’s undivided 40% interest (40% of 100 ounces) multiplied by $1,000, or $1,200.

2. Definitions. Additional terms governing the determination and payment of the Production Royalty are as follows:

A. Property means all interests held as of the date hereof by Barrick in the Cortez Joint Venture properties, including without limitation, the undivided 40% interest held in the following:

(1) the patented and unpatented mining claims and millsites and fee land identified on Exhibit A-1 attached hereto;

(2) the leased areas covered by the leases identified on Exhibit A-2 attached hereto (the “Leases”), subject to the provisions of such leases;

(3) the joint venture agreements identified on Exhibit A-3 attached hereto (the “Joint Venture Agreements”) as to which the Cortez Joint Venture holds, or has the right to acquire, a participating interest, subject to the provisions of such joint venture agreements;

For greater certainty, the term “Property” does not include any properties within the “Area of Interest” (as such term is defined in the Cortez Joint Venture) in which, as of the date of this Rio Tinto Royalty Deed, neither Barrick nor any of its Affiliates hold any mining claims or other real property interest or the right to acquire the same.

B. Refined Gold means gold recovered after the treatment of ores mined from the Property that has been refined to meet or exceed generally accepted commercial standards for the “good delivery” of gold bullion on the U.S. or London commodity exchanges. If only a portion of the gold mined from any part of the Property is delivered to the Cortez Joint Venture as a participant in a Joint Venture Agreement, only the refined gold that is attributable to such portion shall be considered to be Refined Gold for purposes of determining the Royalty.

C. Refined Silver means silver that is recovered after the treatment of ores mined from the Property that has been refined to meet or exceed generally accepted commercial standards for the “good delivery” of silver bullion on the U.S. or London commodity exchanges. If only a portion of the silver mined from any part of the Property is delivered to the Cortez Joint Venture as a participant in a Joint Venture Agreement, only the refined silver that is attributable to such portion shall be considered to be Refined Silver for purposes of determining the Royalty.

D. Gold Production means for a calendar month the number of troy ounces of Refined Gold delivered by a refinery attributable to Barrick’s 40% undivided interest as a tenant in common in the Property and delivered to, or for the account of Barrick (or to any Affiliate of Barrick to be allocated to Barrick) during that month.

E. Silver Production means for a calendar month the number of troy ounces of Refined Silver delivered by a refinery attributable to Barrick’s 40% undivided interest as a tenant in common in the Property and delivered to, or for the account of Barrick (or to any Affiliate of Barrick to be allocated to Barrick) during that month.

F. Monthly Average Gold Price means the average London Bullion Market Association P.M. Gold Fix in U.S. Dollars for a calendar month, calculated by dividing the sum of all such prices reported for the applicable month by the number of days for which such prices were reported, in each case as shown in the Financial Times or other similar publication, but corrected to the actual London Bullion Market Association price in the case of errors. If the London Bullion Market Association P.M. Gold Fix ceases to be made or published, all such references shall be replaced with references to prices of gold for immediate delivery in the most nearly comparable established market selected by Barrick, acting reasonably, as such prices are published in “Metals Week” or a similar publication.

G. Monthly Average Silver Price means the average London Bullion Market Association daily price fixing for silver in U.S. Dollars for a calendar month, calculated by dividing the sum of all such prices reported for the applicable month by the number of days for which such prices were reported, as reported in the Financial Times or other similar publication, but corrected to the actual London Bullion Market Association price in the case of errors. If the London Bullion Market Association daily price fixing for silver ceases to be made or published, all such references shall be replaced with references to prices of silver for immediate delivery in the most nearly comparable established market selected by Barrick, acting reasonably, as such prices are published in “Metals Week” or a similar publication.

H. Gross Value of Refined Gold for a calendar month means the Gold Production for such month multiplied by the Monthly Average Gold Price for that month.

I. Gross Value of Refined Silver for a calendar month means the Silver Production for such month multiplied by the Monthly Average Silver Price for that month.

J. Allowable Deductions means the pro rata portion of royalties as currently exist that are payable to lessors under the Leases or to other parties in respect of production from the Property with respect to the undivided 40% interest of Barrick in the Property. Provided, however, that such deduction shall not continue to apply in respect of any such royalty that Barrick buys out or buys down.

K. Returns means the sum of (i) the Gross Value of Refined Gold and (ii) of the Gross Value of Refined Silver for a calendar month; less Allowable Deductions.

L. Commencement Date means the date when the number of troy ounces of Refined Gold and gold equivalent of Refined Silver delivered after January 1, 2008, from the Property to Barrick and all other Affiliates of Barrick (and not just with respect to the undivided 40% interest held by Barrick) total fifteen (15) million ounces. Gold equivalent of Refined Silver shall be determined by determining the Gross Value of Refined Silver delivered to Barrick and all other Affiliates of Barrick during each month after January 1, 2008 and dividing such amount by the Monthly Average Gold Price for such month. The number so determined shall then be added to the number of ounces of Refined Gold delivered in such month for purposes of determining the Commencement Date.

M. Affiliate means, with respect to any person or entity, any other person or entity that directly or indirectly controls, is controlled by, or is under common control with such person or entity. For purposes of the preceding sentence, “control” means possession, directly or indirectly, of the power to direct or cause direction of management and policies through ownership of voting securities, contract, voting trust, or otherwise.

N. Ounces means troy ounces.

O. Trading Activities means any and all price hedging and price protection activities undertaken by Barrick or its Affiliates with respect to any production from the Property, raw materials, interest rates or currency exchanges including without limitation, any forward sale and/or purchase contracts, spot-deferred contracts, option contracts, speculative purchases and sales of forward, futures and option contracts, both on and off commodity exchanges.

3. Negation of Trading Activities. Trading Activities, and the profits and losses generated thereby, shall not, in any manner, be taken into account in the calculation of royalties due to Royalty Holder, whether in connection with the determination of price, the date of sale, or the date any royalty payment is due. The Royalty Holder acknowledges that Barrick and its Affiliates engaging in Trading Activities may result in

Barrick and its Affiliates realizing from time to time fewer or more profits for Products than does Royalty Holder, since Royalty Holder’s Production Royalty is established by published prices. Similarly, Royalty Holder shall not be obligated to share in any losses generated by any such Trading Activities with respect to the sales of any product covered by this Rio Tinto Royalty Deed, or otherwise.

4. Obligation to Refine. Barrick shall cause gold and silver obtained from ores mined from the Property to be refined to Refined Gold and Refined Silver on an arm’s length basis from reputable independent first class refineries such as Johnson Mathey, or other similar first class refineries. Should any gold or silver ore be required to be processed at any facility of Barrick or its Affiliates outside of the Property in order to produce a product that can be shipped to a refinery to produce Refined Gold and Refined Silver, such processing will be done on arm’s length terms that are no less advantageous to Barrick as to any other Barrick Affiliate using such facilities. Barrick shall at all times be responsible for tracking and accounting for such gold and silver through delivery of Refined Gold and Refined Silver from the refinery for purposes of the determining the Royalty Commencement Date and the Royalty. In the event any gold or silver ore or any intermediate products are lost after transport off of the Property (other than through normal processing loss), then the amount of the ounces of gold and silver in such lost material shall be included as the Gross Value of Refined Gold or the Gross Value of Refined Silver, as the case may be.

5. Calculation and Payment of Royalty.

A. Prior to Commencement Date. Prior to the Commencement Date, Barrick shall provide statements in reasonable detail by each February 1 showing the quantity of Refined Gold (including gold equivalent of Refined Silver) that has been delivered to Barrick and to each other Affiliate of Barrick during the prior calendar year and the cumulative quantity of Refined Gold (including gold equivalent of Refined Silver) that has been so delivered since the Effective Date. Barrick shall promptly give notice to Royalty Holder when the Commencement Date has occurred.

B. Production Royalty After Commencement Date. Beginning on the Commencement Date the Production Royalty shall be computed and accrued on a monthly basis and shall be paid on a quarterly basis within 45 days after the end of each calendar quarter. Production Royalty payments shall be accompanied by a statement in reasonable detail sufficient to allow Royalty Holder to determine the method of computation of each Production Royalty payment and the accuracy thereof.

C. Method of Making Payments. All payments of money required to be made by Barrick to Royalty Holder hereunder shall be made by wire transfer in immediately available funds to Royalty Holder on or before the due date at an account designated by Royalty Holder. Upon making payment as provided herein, Barrick shall be relieved of any responsibility for the distribution of such payment among Royalty Holder and any of its successors and assigns.

6. Accounting Principles.

A. Standards. Barrick shall maintain, or cause to be maintained, true and correct records in accordance with GAAP of all ores mined from the Property and the amounts of gold and silver recovered therefrom and converted to Refined Gold and Refined Silver and any intermediate treatment, including without limitation, records with respect to tonnage, volume of products, analyses of products, weight, moisture, assays of payable metal content and other records, as appropriate. All royalty calculations affecting the Production Royalty shall be determined in accordance with GAAP as applied by Barrick.

B. Audit. Royalty Holder shall have the right to audit such records at Barrick’s office, or at such other office where such records are kept, during normal business hours upon reasonable prior notice, provided such audit is conducted by Royalty Holder or by an accounting firm of recognized standing, at least one of whose members is a member of the American Institute of Certified Public Accountants. Royalty Holder shall make available all books and records, refinery statements, and other invoices, receipts and records necessary for purposes of such audit, and shall make available work space and copying facilities, or permit Royalty Holder’s representatives to install copying facilities for use in connection with its audit activities.

7. General.

A. Right to Inspect. The Royalty Holder or its authorized representative during normal business hours upon reasonable prior notice and not more frequently than twice annually, may inspect and copy all records and data directly pertaining to the computation of its interest and valuation at the office where such records are kept, including without limitation such records and data which are maintained electronically. The Royalty Holder or its authorized representative on reasonable notice to Barrick may enter upon all surface and subsurface portions of the Property for the purpose of inspection the Property, all improvements thereto and operations thereon for the limited purpose of verifying procedures directly related to computation of the Production Royalty and only to the extent and at such frequency as is reasonably necessary to achieve such verification. Royalty Holder shall enter such property at the Royalty Holder’s own risk and may not unreasonably hinder operations on or pertaining to the Property. The Royalty Holder shall indemnify and hold harmless Barrick and its Affiliates (including without limitation direct and indirect parent companies), and its or their respective directors, officers, shareholders, employees, agents and attorneys, from and against any liabilities which may be imposed upon, asserted against or incurred by any of them by reason of injury to the Royalty Holder or any of its agents or representatives caused by the Royalty Holder’s exercise of its rights herein on such property.

B. No Development Covenants. Barrick shall have no obligation to mine, to continue mining, or to mine any particular quantities of gold-bearing or silver-bearing ores from the Property or to recover gold or silver therefrom in respect of the Royalty. Barrick’s only obligation is to pay the Royalty to Royalty Holder on any gold or silver

that is recovered from ores mined from the Property subject to the terms and conditions in this Rio Tinto Royalty Deed. Royalty Holder’s interest in the Property shall be solely that of a non-participating royalty holder and it shall have no rights to participate or influence management or decision-making regarding operations on the Property. Royalty Holder expressly disclaims any implied covenants of diligence with respect to operations on the Property, including without limitation all exploration, development, mining, and processing operations.

C. Interest in Real Property. The Royalty interest provided in this Rio Tinto Royalty Deed shall attach to (i) any amendments, relocations, adjustments, resurvey, additional locations of any existing mining claims or conversions of any mining claims comprising the Property, and any extralateral rights claimed by Barrick pertaining to any interests within the Property, and (ii) to any renewal, amendment or other modification or extensions of any leases of any real property interests now existing or hereafter arising comprising the Property. The Royalty interest is a real property interest that runs with the Property, is perpetual, and shall be applicable to Barrick and its transferees, successors and assigns of the Property; provided, however, that the Royalty shall not be applicable to any lands subject to a joint venture agreement as to which the Cortez Joint Venture has no further participating interest. Barrick acknowledges that the Royalty Holder will record this Rio Tinto Royalty Deed, the costs of which shall be borne by Royalty Holder.

D. Confidentiality. Except as provided in Subsection 7D(1), all information and data provided to the Royalty Holder under the terms of this Rio Tinto Royalty Deed shall not be disclosed by the Royalty Holder to any third party or the public without the prior written consent of Barrick, which consent shall not be unreasonably withheld.

(1) The consent required by this Section shall not apply to a disclosure:

(a) By a Royalty Holder to a potential successor of all or any significant portion of its interests under this Rio Tinto Royalty Deed, or to a potential successor by consolidation or merger, or to a proposed joint venture or partnership in which such Royalty Holder may become a participating partner or venturer;

(b) To an Affiliate or representative that has a bona fide need to be informed (but subject to the obligations of confidentiality herein);

(c) To a governmental agency or to the public which the disclosing Party believes in good faith is required by applicable laws or the rules of any stock exchange;

(d) Made in connection with litigation or arbitration involving a Party where such disclosure is required by the applicable tribunal or is, on the advice of counsel for such Party, necessary for the prosecution of the case, but subject to prior notification to the other Party to enable such Party to seek appropriate protective orders.

(2) Prior to any disclosure described in Subsections 7D(1)(a) or (b) above, such third party shall first agree to protect the confidential information from further disclosure to the same extent as the Parties are obligated under this Section 7D.

E. Commingling. Barrick shall have the right to commingle ore mined from the Property or intermediate products derived after the treatment thereof with ores or intermediate products from lands other than the Property after such ores or products have been weighed or measured, sampled and analyzed in accordance with sound mining and metallurgical practices such that Royalty Holder’s Royalty can be reasonably and accurately determined. Upon request to Barrick, and at Royalty Holder’s expense, Royalty Holder shall have the right to have a representative present at the time all such samples and measurements are taken. Royalty Holder’s representative shall have the right to secure sample splits for the purpose of confirming the accuracy of all measurements. If Royalty Holder’s assay results differ from Barrick’s, Barrick shall perform a check assay. Any remaining disputes concerning assays, or other disputes concerning commingling procedures or results, shall be subject to arbitration as provided in Section 6D hereof.

F. Transfers.

(1) Right of First Offer. Royalty Holder shall not assign or otherwise sell all or any portion of its Royalty interest or its rights established herein as to the Royalty unless Royalty Holder first offers to sell the interest to be assigned or otherwise transferred (the “Offered Interest”) to Barrick as provided in this Section 7F(1). Within thirty (30) days of receipt of such offer, Barrick shall deliver to Royalty Holder the proposed terms of sale of the Offered Interest which shall provide for a price payable in cash in U.S. currency. The said delivery shall constitute an offer by Barrick to purchase the Offered Interest at the price and upon the terms set out in the offer. The Royalty Holder shall have 30 days after receipt of the offer within which to deliver written notice to Barrick of its acceptance or rejection of the offer. If Royalty Holder delivers written notice accepting the offer within the period provided, both parties shall be bound by the terms thereof. If Royalty Holder fails to deliver such acceptance notice within the period provided, the offer shall be deemed not to have been accepted by Royalty Holder. If the Royalty Holder does not deliver the acceptance notice within such period, Royalty Holder may sell the Offered Interest to any other third party upon terms that are no less favorable to Royalty Holder than the terms set forth in the offer from Barrick. If Royalty Holder does not close the transaction within 180 days after expiration of the 30-day acceptance or rejection period referred to above, then Royalty Holder shall once again be obligated to comply with the provisions of this Section prior to selling the Offered Interest. Provided, however, that nothing in the foregoing shall be deemed to apply to any pledge or assignment of the Royalty Interest as collateral in connection with any financing by the Royalty Holder by a non-Affiliate third party.

(2) Notice of Transfer. No assignment or other transfer of all or any portion of Royalty Holder’s Royalty interest or its rights established herein as to the Royalty shall

be binding upon Barrick, regardless of whether Barrick has actual or constructive knowledge of the change of ownership, until the date upon which Barrick has received from the transferee a certified copy of the instrument or instruments of transfer satisfactory, in the opinion of Barrick acting reasonably to evidence the change of ownership and to establish the right, title, or interest of the claiming party and the extent thereof.

(3) Transfer Conditions. No change or division in the ownership of the Production Royalty, however accomplished, shall enlarge the obligations or diminish the rights of Barrick. Royalty Holder covenants that any change in ownership of the Production Royalty shall be accomplished in such a manner that Barrick shall be required to make payments and give notice to no more than one Person, and upon breach of this covenant, Barrick and its Affiliates may retain all payments otherwise due in escrow until the breach has been cured. No change or division in the ownership of the Royalties shall be binding on Barrick until a certified copy of the recorded instrument evidencing the change or division in ownership has been received by Barrick.

(4) Assignment by Barrick. Subject always to this Rio Tinto Royalty Deed, if Barrick transfers all or any portion of its interest in the Property, upon obtaining from the transferee a written assumption of the obligations of Barrick pursuant to this Rio Tinto Royalty Deed with respect to the interest so transferred, Barrick shall thereupon be relieved of all liability for payment of Royalties under this Rio Tinto Royalty Deed for any Royalties that may thereafter arise with respect to such transferred interest, so long as the Royalty established hereby remains a real property interest running with the Property and the effect of which is not thereby threatened. Barrick shall not be relieved of any accrued Royalties unpaid at the time of the transfer.

G. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given (i) when delivered personally, (ii) when received by the addressee, if sent by Federal Express or other generally recognizable express delivery service, (iii) five business days after being sent by certified mail, return receipt requested, or (iv) on the day of transmittal if given by electronic mail (“email”) prior to 5:00 p.m. EST or EDT as may be applicable, on a business day, and on the next following business day if given by email after 5:00 p.m. EST or EDT, as may be applicable, on a business day and on the next business day if given on any day other than a business day at the following addresses (or to such other address for a Party as shall be specified by like notice; provided that notices of a change of address shall be effective only upon receipt thereof).

Email address:

A party may change its address by notice to the other party.

H. Governing Law. The provisions hereof regarding the Royalty shall be interpreted and enforced in accordance with the internal laws of the State of Nevada, excluding any conflict of law principles that would require the application of the laws of any other jurisdiction.

I. Amendment and Waiver. This Rio Tinto Royalty Deed may only be amended by an instrument in writing signed by the Parties hereto. Any term or provision of this Agreement may be waived at any time by the Party or Parties entitled to the benefits thereof but (a) no such waiver shall be effective unless in writing and signed by the Party claimed to have made such waiver, and (b) no waiver of any term, provision or breach of this Rio Tinto Royalty Deed shall operate or be construed as a waiver of the same or any other term or provision, or any other breach of this Rio Tinto Royalty Deed, on any other occasion.

J. Severability. In case any one or more of the provisions contained in this Rio Tinto Royalty Deed shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not effect any other provision hereof, and this Rio Tinto Royalty Deed shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

K. Limitation of Damages. No Party shall be liable to the other hereunder for special, punitive, exemplary, consequential or liquidated damages, loss of profits or any other monetary damages that are not measured by the prevailing Party’s actual damages.

Exhibit C
to
Purchase Agreement

ALLOCATION SCHEDULE

The Tax Purchase Price shall be allocated as follows:

1. Inventory: The fair market value of gold and silver inventory shall be computed by subtracting from the final selling price of the gold and silver produced from the inventory on hand at the Closing Date (or if such data is not available with respect to the Closing Date, the most recent prior date for which such information is available) (“Pricing Date”) the average cost for the month in which the Pricing Date occurs to process said inventory into salable gold and silver.

2. Tangible property other than inventory and Seller’s economic interest in minerals in place: The agreed fair market value of each asset in this category shall be as set forth on the most recent monthly balance sheet available on the Closing Date which has been prepared by the Cortez Joint Venture in a manner consistent with past practice.

3. Seller’s economic interest in minerals in place: The agreed fair market value shall be equal to the Tax Purchase Price minus the portions thereof previously allocated in paragraphs 1 and 2 above.

Of the total amount allocated pursuant to this paragraph 3 to Seller’s economic interest in minerals in place, Purchaser shall prepare and submit to Seller for Seller’s review no later than 20 days after the Closing Date an apportionment of this total amount between Seller’s interest in all fee and leasehold interests (including patented claims) and Seller’s interest in unpatented claims in which Seller has an economic interest in minerals in place. This apportionment shall be made in Purchaser’s reasonable discretion and Seller shall have 10 days to review such apportionment. Following such review, if Purchaser and Seller cannot agree on the apportionment of this item in 15 days, the matter shall be submitted to mediation before a mutually agreed upon accountant experienced in such matters from a major accounting firm.

B. Capitalized terms used but not defined herein shall have the meanings given to them in the Purchase Agreement.

C. In consideration of the Purchase Agreement and the benefits to be obtained by Guarantor and Seller thereunder, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Guarantor has agreed to guarantee, all of the liabilities and obligations of Seller under the Agreements, as hereinafter defined.

GUARANTY

For good and valuable consideration, Guarantor and Beneficiary agree as follows:

1. Guaranty. Guarantor unconditionally and irrevocably guarantees to the Beneficiary the due and punctual payment and performance of all obligations, covenants, liabilities, indemnities and other agreements (whether known or unknown, accrued, absolute, contingent, determined, determinable or otherwise, and whether to be performed, or relating to or arising from events, occurrences, actions, omissions, operations, facts, circumstances or matters occurring, existing or asserted, before, at or after the date of this Guaranty) agreed to, made, or owed, by Seller to Beneficiary and its Affiliates and their directors, officers, agents and employees under the Purchase Agreement and any other agreements or documents delivered in connection with the Purchase Agreement (the Purchase Agreement and all such other agreements and documents collectively, the “Agreements”) (collectively, the “Liabilities and Obligations”).

2. Nature of Guaranty. Guarantor agrees that this Guaranty is an absolute, unconditional, present and continuing guarantee of payment and performance, not of collection, and that its obligations under this Guaranty shall be primary obligations, it being agreed by Guarantor that its obligations under this Guaranty shall not be discharged until the payment and performance in full of the Liabilities and Obligations by Seller or Guarantor. Guarantor

expressly waives all rights it may have now or in the future under any statute, or at common law, or at law or in equity, or otherwise, to compel the Beneficiary to proceed in respect of the Liabilities and Obligations against Seller or any other party or against any security for the payment and performance of the Liabilities and Obligations before proceeding against, or as a condition to proceeding against, Guarantor. In no event shall the Beneficiary have any obligation (although it is entitled, at its option) to proceed against Seller before seeking satisfaction from Guarantor. The Beneficiary may proceed under any of the Agreements, prior or subsequent to, or simultaneously with, the enforcement of the Beneficiary’s rights hereunder.

3. Waiver. Guarantor unconditionally waives, to the fullest extent permitted by law, (a) notice of any matters described herein, (b) all notices which may be required by statute, rule or law to preserve intact any rights against Guarantor, including, without limitation, any demand, presentment and protest, proof of notice of nonpayment under the Agreements and notice of default or any failure of Seller and its Affiliates and its and their successors and assigns to perform or comply with any term, covenant or condition of the Agreements, (c) any requirement of diligence or to exhaust any remedies or to mitigate damages resulting from default under the Agreements, (d) any defense based on any statute of limitations, and (e) any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety or which might otherwise limit recourse against Guarantor. Beneficiary, in its sole discretion, may, without any prejudice to its rights under this Guaranty, at any time or times, without notice to or the consent of Guarantor, modify or amend (with the consent of the Seller) the Liabilities and Obligations under the Agreements. The provisions of this Guaranty are for the benefit of the Beneficiary, and nothing herein contained shall impair, as between Seller and the Beneficiary, the obligations of Seller under the Agreements.

4. Continued Effectiveness. This Guaranty shall remain in full force and effect and continue to be effective in the event any petition is filed by or against Seller or Guarantor for dissolution, liquidation or reorganization; in the event Seller or Guarantor becomes insolvent or makes an assignment for the benefit of creditors; in the event a receiver or trustee is appointed for all or any significant part of Seller’s or Guarantor’s assets; and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Liabilities and Obligations, or any part hereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by the Beneficiary, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Liabilities and Obligations shall be reinstated and deemed reduced only by such amount paid or performed and not so rescinded, reduced, restored or returned.

5. Miscellaneous.

(a) Representations and Warranties. Guarantor hereby represents and warrants to the Beneficiary as of the date hereof that:

been duly and validly executed and delivered by Guarantor and constitutes the legal, valid and binding obligation of each of Guarantor, enforceable against Guarantor in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency or other similar laws from time to time in effect which affect the enforcement of creditors’ rights generally and by general principles of equity.

Guarantor shall not assign, delegate or otherwise transfer its obligations hereunder, in whole or in part, and any attempt to so transfer in violation of the foregoing shall be void ab initio. Guarantor acknowledges and agrees that Beneficiary may assign its rights hereunder to any of its Affiliates.
