ARTICLE 7
COVENANTS

7.1 Conduct of Operations

(a) All decisions regarding the Prosperity Project, including all decisions concerning the methods, extent, times, procedures and techniques of any (i) exploration, development and mining related to the Prosperity Project, including spending on capital expenditures, (ii) leaching, milling, processing or extraction, (iii) materials to be introduced on or to the Prosperity Project, and (iv) except as provided herein, the sales of Minerals and terms thereof shall be made by Taseko, in its sole discretion. Without limiting the generality of the foregoing, Taseko shall be permitted to amend the mine plan for the Prosperity Project at any time and from time to time in its sole discretion, provided that it is acting in a commercially reasonable manner and not inconsistent with accepted Canadian mining practice.

(b) Notwithstanding Section 7.1(a), Taseko agrees that it shall carry out and perform all mining operations and activities pertaining to or in respect of the Prosperity Project in a commercially reasonable manner and in accordance with Applicable Laws, all applicable licences, permits and other authorizations and accepted mining, processing, engineering and environmental practices prevailing in the mining industry. For greater certainty, nothing in this Agreement shall require Taseko or any of its Affiliates or any other person to construct, operate or continue operating the Prosperity Project or to explore or develop the Prosperity Project.

(c) Notwithstanding Section 7.1(a), Taseko shall ensure that (i) all cut-off grade, short term mine planning and production decisions concerning the Prosperity Project shall be based on copper and gold prices typical of normal industry practice and consistent with the practices of Taseko and its Affiliates as at the date of this Agreement in connection with such decisions (and not on the Fixed Price), and (ii) all longer term planning and resource and reserve calculations concerning the Prosperity Project shall use copper and gold prices based on normal industry practice and consistent with the historical practices of Taseko and its Affiliates in connection with such planning and calculations. For greater certainty, the intent of this provision is that Taseko and its Affiliates operate the Prosperity Project as though Taseko had a full economic interest in all the gold produced from the Prosperity Property.

7.2 Preservation of Corporate Existence

(a) Taseko shall at all times during the term of this Agreement do and cause to be done all things necessary or advisable to maintain its corporate existence.

7.3 Processing/Commingling

(a) Taseko shall not, and shall cause each of its Affiliates to not, process Other Minerals through the Prosperity Processing Plant in priority to, or commingle Other Minerals with, Minerals mined, produced, extracted or otherwise recovered from the Prosperity Property, unless Taseko (or such Affiliate) has adopted and employs reasonable practices and procedures for weighing, determining moisture content, sampling and assaying and determining recovery factors and

Taseko or such Affiliate keeps appropriate records in this regard and Taseko shall compensate the Purchaser for any disadvantage incurred or suffered by the Purchaser if and to the extent that the processing of Minerals mined, produced, extracted or otherwise recovered from the Prosperity Property through the Prosperity Processing Plant is delayed solely as a result of such Other Minerals being processed through the mill.

(b) If during the Term of the Agreement ore is processed through the Prosperity Processing Plant that is not sourced from the Prosperity Property and as a result ore which is in the reserve category at the Prosperity Property is displaced from the Prosperity Processing Plant then the amount of Produced Gold will be calculated based on the deemed amount of gold in concentrate, which amount shall be the amount of gold in concentrate that would have been produced had ore which is in the reserve category at the Prosperity Property not been displaced. The calculation of the deemed amount of gold in concentrate shall only deviate from the actual amount of gold in concentrate in respect of that amount of ore which is 70,000tpd less the amount of ore processed that is sourced from the Prosperity Property, multiplied by the average grade of remaining reserves, multiplied by the weighted average life of mine gold recovery. The deemed amount of gold in concentrate shall be calculated in the sole discretion of the Independent Engineer.

7.4 Mineral Offtake Agreements

(a) During the Term, Taseko shall be a party to the Mineral Offtake Agreements and Taseko shall be responsible for delivering all Minerals that include Produced Gold to each Offtaker, in such quantity, description and amounts and at such times and places as required under and in accordance with each Mineral Offtake Agreement. Taseko shall notify the Purchaser in writing that a Lot is being delivered to an Offtaker at least one Business Day before the Lot leaves the Prosperity Processing Facility. Taseko shall deliver by e-mail to the Purchaser, within five Business Days after such are available and/or prepared, copies of all documents, certificates and instruments pertaining to each Lot, including without limitation, all invoices, credit notes, bills of lading, certificates indicating Taseko’s provisional shipped moisture content and provisional shipped assays and any and all documentation prepared or produced by the Offtaker in respect of the Produced Gold, including without limitation, all analyses and assays.

Taseko shall notify the Purchaser in writing when any dispute arising out of or in connection with any such Mineral Offtake Agreement is commenced in respect of Produced Gold and shall provide the Purchaser with timely updates of the status of any such dispute and the final decision and award of the court or arbitration panel with respect to such dispute, as the case may be.

(d) Taseko shall ensure that the final sale and delivery of Produced Gold (as opposed to the sale and delivery of Refined Gold credited to the account of Taseko or its Affiliate in respect of any Gold Delivery of Produced Gold to an Offtaker) shall only be made to an Offtaker. For greater certainty, nothing in this Section 7.4(d) shall prohibit the processing of Produced Gold by Taseko and its Affiliates, provided that such Produced Gold is eventually sold to an Offtaker.

7.5 Insurance

(a) Taseko shall maintain with reputable insurance companies insurance with respect to the Prosperity Project and the operations conducted on and in respect of the Prosperity Project against such casualties and contingencies and of such types and in such amounts as is customary in the case of similar operations and shall have the Purchaser added as a named insured and loss payee in the insurance policies.

(b) Taseko shall ensure that each shipment of Produced Gold is adequately insured in such amounts and with such coverage as is customary in the mining industry, until the time that risk of loss and damage for such Produced Gold is transferred to the Offtaker.

(c) Where Taseko or its Affiliate receives payment under any insurance policy in respect of a shipment of Produced Gold that is lost or damaged after leaving the Prosperity Project and before the risk of loss or damage is transferred to the Offtaker, Taseko shall sell and deliver to the Purchaser (without duplication to the extent previously sold and delivered to the Purchaser by Taseko) an amount of Refined Gold having a value on the date of delivery (based on the Market Price on the date of delivery) of 100% of the amount of the insurance payment received by Taseko or its Affiliate in respect of the Designated Percentage of such shipment of Produced Gold.

(d) Taseko shall insure the Prosperity Project in such amounts and with such coverage as is customary in the Canadian mining industry for the construction, Development and operation of the Prosperity Project, including the Property Processing Plant. Taseko covenants and agrees that in the event of any loss or damage that is insured prior to the date on which the uncredited balance of the Payment Deposit has been reduced to nil, Taseko shall either (i) use all insurance proceeds to rebuild or repair all damaged facilities forming part of the Prosperity Project, or (ii) pay to the Purchaser within 30 days after receipt of such proceeds by Taseko the Purchaser’s share of the insurance proceeds, calculated as the ratio of the Payment Deposit to the original Project Costs prior to any adjustments.

7.6 Project Financing and Other Permitted Debt Financings and Permitted Encumbrances

(a) Taseko agrees that, with respect to any secured Project Financing that Taseko arranges for the Prosperity Project, the Project Financing shall provide that the Project Lenders (or any agent or trustee that holds their Project Security) will enter into an intercreditor agreement with the Purchaser and Taseko on terms acceptable to the Purchaser, acting reasonably, under which, inter alia, the Project Lenders and the Purchaser and the other parties thereto would agree that:

(i) Taseko’s obligation to deliver the Designated Percentage of Produced Gold to the Purchaser against payment of the Gold Purchase Price (and subject to Taseko’s right to credit the relevant portion of the Gold Purchase Price against the Payment Deposit pursuant to this Agreement) shall rank ahead of any obligation to the Project Lenders, provided however that the Project Lenders’ obligations will not in any event include the obligation to make the minimum delivery obligations under Section 7.8 during any period that the Project Lenders or any receiver or receiver manager are in possession of the Prosperity Project of any part thereof during a realization or insolvency proceeding, with each minimum delivery obligation that is not made when due accruing as a continuing obligation to the Purchaser, together with interest at a rate equal to the six month LIBO Rate plus 4 % per annum calculated and compounded monthly in arrears from the date that such minimum delivery obligation becomes due until it is made;

(ii) subject to the foregoing, the Purchaser would subordinate the Purchaser’s security interest under the Security Agreements to the Project Security for the Project Financing with respect to the application of proceeds on a distribution on a realization;

(iii) for the purposes of determining the amount owing to the Purchaser on a distribution on a realization, such amount would be the then uncredited Payment Deposit and any produced, but undelivered, Refined Gold;

(iv) either the Project Lenders or the Purchaser would be entitled to take action on the occurrence of an event of default under the Project Financing or this Agreement, as applicable, on 10 days prior written notice to the other (provided that the Project Lenders or the Purchaser may give notice to Taseko under the Bankruptcy and Insolvency Act (Canada) before the end of such 10 day period and without notice to the other);

(v) the Project Lenders’ rights of realization and sale in a default situation would be subject to the obligation to make any transferee of the Prosperity Project or any portion of the Prosperity Project (including the Project Lenders if they take title to the Prosperity Project or any such portion) acknowledge, and agree directly with the Purchaser to assume severally (in proportion to their interests) with any other holders of an interest in the Prosperity Project:

(A) the obligation of Taseko to deliver after the date of the transfer, the Designated Percentage of Produced Gold to the Purchaser against payment of the Gold Purchase Price on the terms of this Agreement (and subject to Taseko’s right to credit the relevant portion of the Gold Purchase Price against the Payment Deposit);

(B) the Security Agreements as security for the uncredited Payment Deposit and other obligations under this Agreement assumed by such transferee; and

(vi) the carriage of the realization process would be with the person with the greater claim at the commencement of the realization; and

(vii) other reasonable terms and provisions, including any relating to mutual cure rights, notices, and other remedies, would be included.

(b) The Purchaser agrees that it will permit secured debt on the Prosperity Project (in addition to Project Financing) where, in the Purchaser’s opinion, acting reasonably, such debt could be supported by the Prosperity Project, and the Purchaser will subordinate the Purchaser’s security interest under the Security Agreement to the security for such additional debt by entering into an

intercreditor agreement substantially on the terms and conditions set out in the preceding paragraph.

(c) If there is more than one secured Project Financing at any one time, Taseko, the Purchaser and all Project Lenders, will enter into a single intercreditor agreement.

(d) Financing that Taseko arranges for the Prosperity Project, that is secured only by mobile mining equipment, motor vehicles, office equipment or assets not required to operate the Prosperity Project is permitted and the secured party(ies) under such financing shall be entitled to priority over the Security Agreements and shall not be required to enter into an intercreditor agreement with the Purchaser. Operating leases of mobile mining equipment, motor vehicles, office equipment and assets not required to operate the Prosperity Project are also permitted.

(e) Debt financing that Taseko arranges that is unsecured or is secured only by assets not forming part of the Prosperity Project are permitted and the lender(s) under such debt financing shall be entitled to priority over the Security Agreements and shall not be required to enter into an intercreditor agreement with the Purchaser.

(f) Taseko may pledge to an Offtaker warehouse holding certificates in respect of Minerals that have been delivered to a warehouse for delivery to an Offtaker as security for any prepayment by the Offtaker on credit terms for the purchase of Minerals by the Offtaker pending delivery of, and transfer of title to, the Minerals, and such pledges shall have priority over the Security Agreements, subject to the parties agreeing on a protocol to estimate the Produced Gold in Minerals .

(g) The security interests referred to herein which are registered in the Personal Property Security Registry are Permitted Encumbrances.

7.7 Confidentiality

(a) Each Party (a “Receiving Party”) agrees that it shall maintain as confidential and shall not disclose, and shall cause its Affiliates, employees, officers, directors, advisors, agents and representatives to maintain as confidential and not to disclose, the terms contained in this Agreement and all information (whether written, oral or in electronic format) received or reviewed by it as a result of or in connection with this Agreement, including any draft or final technical reports provided under Section 6.4(b), any Mineral Offtake Agreement provided under Section 7.4(a) and the information received by it pursuant to the confidentiality agreement dated January 20, 2010 between the Purchaser and Taseko (“Confidential Information”), provided that a Receiving Party may disclose Confidential Information in the following circumstances:

(i) to its auditor, legal counsel, lenders, brokers, underwriters and investment bankers and to persons with which it is considering or intends to enter into a transaction for which such Confidential Information would be relevant, provided that such persons are advised of the confidential nature of the confidential information, undertake to maintain the confidentiality of it and are strictly limited in their use of the confidential information to those purposes necessary for such persons to perform the services for which they were, or are proposed to be, retained by the Receiving Party or to consider or effect the applicable transaction, as applicable;

(ii) subject to Sections 7.7(c) and 13.6, where that disclosure is necessary to comply with Applicable Laws or court order, provided that such disclosure is limited to only that

Neither Party shall file this Agreement on SEDAR without reasonable prior consultation with the other Party, provided that such reasonable prior consultation shall not prohibit either Party from filing this Agreement on SEDAR redacted only to the extent such Party considers it permitted pursuant to Applicable Laws.

(d) Taseko and the Purchaser will consult with each other before issuing any press release or otherwise making any public disclosure and shall not issue any such press release or make any such public disclosure before receiving the consent of the other party. Nothing in this Section 7.7(d) prohibits any party from making a press release or other disclosure required by Applicable Laws or by the policies of any stock exchange if the party making the disclosure has first consulted with the other party hereto.

7.8 Minimum Delivery

Taseko shall deliver to the Purchaser, for the period commencing on the earlier of the Operations Start Date and 27 months after the Commencement Date, on a monthly basis, a minimum amount of Produced Gold [REDACTED — CALCULATION]. The first month that such minimum delivery is applicable will correspond to the first month of production in the Detailed Operating Plan.

The obligation to deliver a minimum amount of Produced Gold will end on the date that is the earlier of the Completion Date and the Adjustment Date as defined in clause 3 of Schedule J.

7.9 Amendments to Development Plan and Project Costs

If, at any time, the Development Plan, the Operating Plan, the Permitting Schedule (Schedule D) and/or Project Costs are subject to a material amendment or amendments as required by the progress of the Development or operation of the Prosperity Project, then, within 15 days after such amendment or amendments is or are made, the amended plan or schedule shall be provided by Taseko to the Purchaser and the Independent Engineer.

7.11 Mineral Tenures and Security

With respect to the Mineral Claims, Mining Leases and Surface Rights now or hereafter forming part of the Prosperity Project, Taseko covenants and agrees that:

(b) it will notify the Purchaser within five days after the conversion of any Mineral Claim into a Mining Lease of such conversion;

(c) it shall use reasonable commercial efforts to have such of the Prosperity Property titles raised to the Land Titles system as is contemplated by Schedule G;

(e) it will update Schedule G from time to time to reflect any of (a) to (c) above and the acquisition of any additional Mining Leases, Mineral Claims or Surface Rights (without increasing the physical or subsurface area of the Prosperity Project outside of the Mineral Claims existing as of the date hereof).

7.12 Negative Pledge

Taseko shall not mortgage, charge, grant any right, title or interest in or to, grant or allow to exist any Encumbrance in respect of or otherwise encumber, the Prosperity Project or the Prosperity Property or its rights, benefits and privileges under this Agreement, except in accordance with Section 7.6.

7.13 Expropriation

In the event of any act of eminent domain, expropriation or nationalization of all or part of the Prosperity Property having the effect of reducing the amount of Produced Gold (an “Expropriation”), Taseko shall pay to the Purchaser the Purchaser’s share of the compensation received by Taseko for such Expropriation within 30 days after receipt of such compensation by Taseko, the Purchaser’s share being calculated as the ratio of the fair value of the Purchaser’s interest in the Prosperity Project as represented by its rights under this Agreement to the value of Taseko’s interests in the Prosperity Project when measured by the same criterion which establishes the value of the Purchaser’s interest. A failure to agree on the foregoing proportion is arbitrable under Section 12.6.

ARTICLE 8
THE PURCHASER PURCHASE RIGHTS, TASEKO TRANSFERS AND CONTROL

8.1 Right of First Offer on Gold Interest

(a) Subject to Section 8.4, if, at any time and from time to time , Taseko or any of its Affiliates (together in Section 8.1 the “Vendor”) wishes to offer for sale to any third party or, following the offer by a third party (other than an Affiliate of the Vendor which enters into an agreement in favour of the Purchaser, in form and substance satisfactory to the Purchaser, acting reasonably, whereby such Affiliate agrees to assume, perform and be bound by the obligations of the Vendor set out in this Section 8.1) to purchase (i) a gold royalty, (ii) an amount of gold based on production from any portion of the Prosperity Property, or (iii) any participating interest in gold based on production, then the Vendor shall, by notice in writing to the Purchaser, first offer to sell such gold, royalty or participating interest to the Purchaser at the price and upon substantially the terms that the Vendor proposes to offer or accept from to a third party (the “Vendor Offer”). Notwithstanding anything to the contrary herein, if the gold, royalty or participating interest represents less than 50% of the fair market value of the assets the Vendor wishes to offer for sale to a third party, then this Section 8.1(a) shall not apply to such offer to sell to a third party.

(b) Upon receipt of a Vendor Offer, the Vendor, and the Purchaser shall negotiate in good faith for a period of up to 45 days commencing on the date of delivery by the Vendor to the Purchaser of the Vendor Offer (the “Negotiation Period”) the definitive terms of an agreement for the purchase and sale of the gold, royalty or participating interest which is the subject of the Vendor Offer (the “Definitive Agreement”).

(i) Vendor shall keep confidential and shall not disclose to any third party any of the terms under negotiation between the Purchaser and Taseko or the Vendor or that such negotiations are occurring; and

(ii) Vendor shall not solicit expressions of interest with respect to, or otherwise negotiate or enter into any agreement with third parties for, the sale of the gold which is the subject of the Vendor Offer.

(d) If, during the Negotiation Period, the Vendor and the Purchaser agree on the terms of the Definitive Agreement, then the Vendor, and the Purchaser shall enter into the Definitive Agreement and proceed to close the transaction as soon as possible thereafter pursuant to the terms of such Definitive Agreement.

(e) If, during the Negotiation Period, the Vendor and the Purchaser are unable to agree on the terms of, and enter into, the Definitive Agreement, then, on the earlier of (i) the last day of the Negotiation Period, and (ii) the day on which the Vendor, and the Purchaser agree that negotiations have ended, the Vendor may commence negotiations with a third party for the sale of the gold, royalty or participating interest which is the subject of the Vendor Offer, and, either directly or through an Affiliate, sell the gold, royalty or participating interest that is the subject of the Vendor Offer to a third party; provided that the terms of sale are no more favourable to such third party than those offered to the Purchaser in the Vendor Offer (prorated to the extent that the Vendor sells only a portion of the gold, royalty or participating interest to such third party).

(f) For the avoidance of doubt, this Section 8.1 shall not apply to any (i) gold spot sales, (ii) gold forward sales or options or other gold sales or gold loans to a financial institution or bullion bank, (iii) internal transfers among Vendor and its Affiliates, provided that any such transfer complies with Section 7.4(d), (iv) any private or public offering of securities that are backed by gold, paid in gold, priced based on gold prices or have payment obligations based on gold prices, or (v) any Mineral Offtake Agreement.

(g) This Section 8.1 shall survive termination of this Agreement for a period of three years following any termination.

8.2 Transfers of the Prosperity Project

(a) Subject to Section 8.4(b), Taseko shall not sell, transfer, assign, convey, grant any right, title or interest in or to, or otherwise dispose of, all or any part of the Prosperity Project except with the prior written consent of the Purchaser, such consent not to be unreasonably withheld. If the Purchaser consents to any such transfer of all or any part of the Prosperity Project pursuant to this Section 8.2(a), then the Purchaser shall release Taseko from its obligations under this Agreement provided such obligations are assumed by the transferee or guaranteed by a person who is a person with sufficient financial resources to perform such obligations (as determined by the Purchaser, acting reasonably) by an instrument in writing in favour of the Purchaser;

(b) Notwithstanding Section 8.2(a) above, this Section 8.2 shall not prohibit any relinquishment, surrender or termination of all or any part of any mining rights, leases, or mineral claims constituting the Prosperity Project if Taseko determines that the cost of maintaining such relinquished, surrendered or terminated mining rights, leases, or mineral claims is not justified. If Taseko acquires or reacquires any mining rights, leases, or mineral claims that cover or relate to any previously released portion of the Prosperity Project, this Agreement shall apply fully to such acquired or reacquired portion.

(c) Notwithstanding Section 8.2(a) above, this Section 8.2 shall not require Taseko to obtain the consent of the Purchaser to entering into a joint venture with another person or persons with respect to the Prosperity Project provided that:

(i) Taseko retains at least a 50% undivided interest in the Prosperity Project;

(ii) Taseko is at all times the operator of the Prosperity Project; and

(iii) each joint venture participant agrees in a document, or documents, acceptable to the Purchaser, acting reasonably, with Taseko, the Purchaser and any other joint venture participant to assume its proportionate share of all of the obligations and duties under this

Agreement and to acknowledge and assume the obligations under the Security Agreement or

(iv) Taseko agrees to be responsible for the full Designated Percentage of Produced Gold as if Taseko were still the 100% owner; and

(v) in either event, all filings have been made and all other actions have been taken that are required in order for the Purchaser to continue at all times following such transfer to have a valid and perfected security interest in the Prosperity Property and the Produced Gold.

The Purchaser agrees that it not be reasonable to withhold consent to a public listed operator of ability equal to Taseko becoming the operator of the Prosperity Property.

(d) In addition to the conditions set forth in Section 8.2(a) above, neither Taseko nor any Project lender shall sell, transfer, assign, convey, grant a right, title or interest in or to, or otherwise dispose of, all or any part of the Prosperity Project to a Restricted Person.

8.3 Change in Control of Taseko

Prior to the Operations Start Date, Taseko shall not agree to or enter into any agreement, arrangement or transaction with any person that would cause, or otherwise allow or permit to exist a Change of Control of Taseko, unless the party that acquires control of Taseko acknowledges, confirms and agrees in favour of the Purchaser that Taseko’s obligations under this Agreement, continue in full force and effect despite such Change of Control.

8.4 Exceptions

(a) The rights of the Purchaser pursuant to Section 8.1 shall be subject to the provisions of any intercreditor agreement pursuant to Section 7.6 and shall not terminate upon a realization by the Project Lenders, if applicable.

(b) Section 8.2 shall not apply to any grant of an Encumbrance on all or any portion of the Prosperity Project that is permitted under Section 7.6. Section 8.2 shall apply to any sale, transfer, assignment, conveyance, grant of any right, title or interest in or to or other disposition of all or any portion of any the Prosperity Project in connection with or resulting from a realization by the Project Lenders, if applicable, which realization shall be subject to the provisions of any Intercreditor Agreement pursuant to Section 7.6.

(b) For greater certainty, if the Purchaser does not exercise its right under Section 10.2(a), the obligation of Taseko or any successor on a realization hereunder shall continue in full force and effect.

1. Initiation of Arbitration Proceedings

(a) If either Party to this Agreement wishes to have any matter under this Agreement arbitrated in accordance with the provisions of this Agreement, it shall give notice to the other Party hereto specifying particulars of the matter or matters in dispute and proposing the name of the person it wishes to be the single arbitrator. Within 20 days after receipt of such notice, the other Party to this Agreement shall give notice to the first Party advising whether such Party accepts the arbitrator proposed by the first Party. If such notice is not given within such 20-day period, the other Party shall be deemed to have accepted the arbitrator proposed by the first Party.

Within 20 days of the appointment of the Arbitrator, the Party initiating the arbitration (the “Claimant”) shall send the other Party (the “Respondent”) a statement of claim setting out in sufficient detail the facts and any contentions of law on which it relies, and the relief that it claims.

(i) Within 15 days of the receipt of the statement of claim, the Respondent shall send the Claimant a statement of defence stating in sufficient detail which of the facts and contentions of law in the statement of claim it admits or denies, on what grounds, and on what other facts and contentions of law he relies.

(ii) Within ten days of receipt of the statement of defence, the Claimant may send the Respondent a statement of reply.

(iii) All statements of claim, defence and reply shall be accompanied by copies (or, if they are especially voluminous, lists) of all essential documents on which the Party concerned relies and which have not previously been submitted by any Party, and (where practicable) by any relevant samples.

(iv) After submission of all the statements, the Arbitrator will give directions for the further conduct of the arbitration.

3. Meetings and Hearings

(a) The arbitration shall take place in Toronto, Ontario or in such other place as the Claimant and the Respondent shall agree upon in writing. The arbitration shall be conducted in English unless otherwise agreed by such Parties and the Arbitrator. Subject to any adjournments which the Arbitrator allows, the final hearing will be continued on successive working days until it is concluded.

(b) All meetings and hearings will be in private unless the Parties otherwise agree.

(d) Each Party may examine, cross-examine and re-examine all witnesses at the arbitration.

4. The Decision

(a) The Arbitrator will make a decision in writing and, unless the Parties otherwise agree, will set out reasons for decision in the decision.

(vi) receive and take into account such written or oral evidence tendered by the Parties as the Arbitrator determines is relevant, whether or not strictly admissible in law;

(vii) make one or more interim awards;

(viii) hold meetings and hearings, and make a decision (including a final decision) in Toronto, Ontario or elsewhere with the concurrence of the Parties thereto;

(c) all Proceeds and Replacements of or to Collateral referred to in clauses (a) and (b) above, including all rights thereto.

2.2 Attachment

Taseko acknowledges that value has been given, that Taseko and the Purchaser have not agreed to postpone the time for attachment of the Security and that the Security is intended to attach, as to all of the Collateral in which Taseko now has rights, when Taseko executes this Security Agreement, and, as to all Collateral in which Taseko only has rights after the execution of this Security Agreement, when Taseko first has such rights. For certainty,

Taseko confirms and agrees that the Security is intended to attach to all present and future Collateral of Taseko and each successor of Taseko.

2.3 Permitted Dispositions

Taseko shall not sell, consign, lease, move, destroy or otherwise dispose of, impair or abandon any Collateral except as permitted by this Agreement or the Purchase Agreement.

2.4 Proceeds Held in Trust

After an Event of Default occurs, Taseko shall receive and hold all Proceeds in trust, separate and apart from other monies, instruments or property, and shall forthwith endorse as necessary and pay over or deliver them to the Purchaser.

2.5 Surface Rights, Mineral Claims and Mining Leases

(a) The last day of the term of any lease, oral or written, or any agreement therefor, now held or hereafter acquired by Taseko shall be excepted from the Security and shall not form part of the Collateral but Taseko shall stand possessed of such one day remaining upon trust to assign and dispose of the same as the Purchaser directs. Subject to Section 2.5(c), if any such lease or agreement therefor contains a provision which provides in effect that such lease or agreement may not be assigned, sub-leased, charged or made the subject of any Lien without the consent of the lessor, the application of the Security to any such lease or agreement shall be conditional upon such consent being obtained.

(b) Upon any sale by the Purchaser or any Receiver of any leasehold interest pursuant to this Security Agreement, the Purchaser or any Receiver, for the purpose of vesting the one day residue of the term or renewal thereof in any purchaser or purchasers, shall be entitled by deed or writing to appoint such purchaser or purchasers or any other Person or Persons a new trustee or trustees of the aforesaid reside of any such term or renewal thereof in the place and stead of Taseko and to vest the same accordingly in the new trustee or trustees so appointed free from any obligation respecting the same.

(c) Notwithstanding anything to the contrary contained herein, if Taseko cannot lawfully grant the Security in any Surface Right, Mineral Claim or Mining Lease comprised in the Collateral in which it now or hereafter has rights because the Surface Right, Mineral Claim or Mining Lease prohibits or restricts such Security, the Surface Right, Mineral Claim or Mining Lease requires the consent of any Person which has not been obtained or the grant of such Security in the Surface Right, Mineral Claim or Mining Lease would contravene Applicable Law, that Surface Right, Mineral Claim or Mining Lease shall not, to the extent it would be illegal or result in a breach or default under that Surface Right, Mineral Claim or Mining Lease (each, a “Prescribed Right”), be subject to the Security (save to the extent provided below) unless and until such agreements, consents, waivers

and approvals as may be required to avoid such illegality, breach or default have been obtained (“Required Approvals”). The Security shall nonetheless immediately attach to any rights of Taseko arising under, by reason of, or otherwise in respect of such Surface Right, Mineral Claim or Mining Lease such as the right to receive payments thereunder and all Proceeds and Replacements of the Surface Right, Mineral Claim or Mining Lease (“Related Rights”), if and to the extent and as at the time such attachment to the Related Rights is not illegal or would not result in a breach or default thereunder.

(d) To the extent permitted by Applicable Law and the Prescribed Rights, Taseko will hold in trust for the Purchaser, and provide the Purchaser with the benefits of, each Prescribed Rights and will enforce all Related Rights at the direction of the Purchaser or at the direction of such other Person (including any purchaser of Collateral from the Purchaser or any Receiver) as the Purchaser may designate.

updated version of such Schedule 2.1, showing additions and deletions to the Collateral since the prior version forming a part hereof, provided however that any such addition shall not result in increasing the physical or subsurface area of the Prosperity Project outside of the Mineral Claims existing as of the date hereof.

ARTICLE 6
REMEDIES ON DEFAULT

6.1 Remedies of Purchaser

If the Security becomes enforceable in accordance with Article 5, the Purchaser shall have the rights set out in this Article 6.

6.2 Right to Appoint a Receiver

expressly provided in the instrument appointing them, so act severally and not jointly and severally. The appointment of any Receiver or anything done by a Receiver or the removal or termination of any Receiver shall not have the effect of constituting the Purchaser a mortgagee in possession in respect of the Collateral.

6.3 Rights of a Receiver

Any Receiver appointed by the Purchaser shall have the following rights:

(a) Power of Entry. Taseko shall forthwith upon demand deliver to a Receiver possession of any Collateral at the place specified by the Receiver. Any Receiver may at any time enter upon any premises owned, leased or otherwise occupied by Taseko or where any Collateral is located to take possession of, disable or remove any Collateral, and may use whatever means the Receiver considers advisable to do so.

(b) Power of Sale. Any Receiver may sell, lease, consign, license, assign or otherwise dispose of any Collateral by public auction, private tender or private contract with or without notice, advertising or any other formality, all of which are hereby waived by Taseko to the extent permitted by Applicable Law. Any Receiver may, at its discretion, establish the terms of such disposition, including terms and conditions as to credit, upset, reserve bid or price. All payments made pursuant to such dispositions shall be credited against the Obligations only as they are actually received. Any Receiver may buy in, rescind or vary any contract for the disposition of any Collateral and may dispose of any Collateral again without being answerable for any loss occasioned thereby. Any such disposition may take place whether or not the Receiver has taken possession of the Collateral. The exercise by the Receiver of any power of sale does not preclude the Receiver from further exercise of its power of sale in accordance with this clause.

(c) Carrying on Business. With respect to, and to the extent of, the Collateral and the Prosperity Property, any Receiver may carry on, or concur in the carrying on of, any of the business or undertaking of Taseko and may, to the exclusion of all others, including Taseko after five Business Days written notice, enter upon, occupy and use any of the premises, buildings, plant and undertaking of, or occupied or used by, Taseko and, for such time and such purposes as the Receiver sees fit, may use any of the equipment and intangibles of Taseko that Taseko has not removed from the Prosperity Property within five Business Days after the Purchaser or the Receiver has given Taseko written notice to do so. No Receiver shall be liable to Taseko for any negligence in so doing or in respect of any rent, charges, costs, depreciation or damages in connection with any such action.

(d) Any Receiver may complete any unfinished construction upon or in the Collateral including having the power to:

(i) appoint and engage superintendents, architects, engineers, miners, geologists, consultants, contractors, managers, advisors and such other

personnel which, in the discretion of the Receiver, may be required to construct, furnish or operate the Collateral;

(ii) enter into contracts for the supply of materials and services which the Receiver deems necessary to complete or operate the Collateral;

(e) Pay Liens. Any Receiver may pay any liability secured by any actual or threatened Lien against any Collateral. A Receiver may borrow money for the maintenance, preservation or protection of any Collateral or for carrying on any of the business or undertaking of Taseko with respect to, and to the extent of, the Collateral and the Prosperity Property and may grant Liens in any Collateral in priority to the Security as security for the money so borrowed. Taseko will forthwith on demand reimburse the Receiver for all such payments and borrowings.

(f) Dealing with Collateral. Any Receiver may seize, collect, realize, dispose of, enforce, release to third parties or otherwise deal with any Collateral in such manner, upon such terms and conditions and at such time as it deems advisable without notice to Taseko (except as otherwise required by Applicable Law), and may charge on its own behalf and pay to others its costs and expenses (including legal, Receiver’s and accounting fees and expenses on a full indemnity basis) incurred in connection with such actions. Taseko will forthwith upon demand reimburse the Receiver for all such costs or expenses.

(g) Powers re Collateral. Any Receiver may have, enjoy and exercise all of the rights of and enjoyed by Taseko with respect to the Collateral or incidental, ancillary, attaching or deriving from the ownership by Taseko of the Collateral, the right to commence or continue Litigation to preserve or protect Collateral and the right to grant or agree to Liens and grant or reserve profits a prendre, easements, rights of ways, rights in the nature of easements and licenses over or pertaining to the whole or any part of the Collateral.

(h) Retain Services. Any Receiver may retain the services of such real estate brokers and agents, lawyers, accountants, appraisers and other consultants as the Receiver may deem necessary or desirable in connection with anything done or to be done by the Receiver or with any of the rights of the Receiver set out herein and pay their commissions, fees and disbursements (which payment shall constitute part of the Receiver’s disbursements reimbursable by Taseko hereunder). Taseko shall forthwith on demand reimburse the Receiver for all such payments.

6.4 Right to have Court Appoint a Receiver

The Purchaser may, at any time, apply to a court of competent jurisdiction for the appointment of a Receiver, or other official, who may have powers the same as, greater or lesser than, or otherwise different from, those capable of being granted to a Receiver appointed by the Purchaser pursuant to this Security Agreement.

6.5 Purchaser may exercise rights of a Receiver

In lieu of, or in addition to, exercising its rights under Sections 6.3 and 6.4, the Purchaser has, and may exercise, any of the rights which are capable of being granted to a Receiver appointed by the Purchaser pursuant to this Security Agreement.

6.6 Retention of Collateral

The Purchaser may elect to retain any Collateral in satisfaction of the Obligations. The Purchaser may designate any part of the Obligations to be satisfied by the retention of particular Collateral which the Purchaser considers to have a net realizable value approximating the amount of the designated part of the Obligations, in which case only the designated part of the Obligations shall be deemed to be satisfied by the retention of the particular Collateral.

6.7 Limitation of Liability

Neither the Purchaser nor any Receiver shall be liable or accountable for any failure of the Purchaser or any Receiver to seize, collect, realize, dispose of, enforce or otherwise deal with any Collateral nor shall any of them be bound to institute Litigation for any such purposes or for the purpose of preserving any rights of the Purchaser, Taseko or any other Person in respect of any Collateral. Neither the Purchaser nor any Receiver shall be liable or responsible for any loss and expense whatever which may accrue in consequence of any such failure resulting from any negligence of the Purchaser, any Receiver or any of their respective Representatives or otherwise. If any Receiver or the Purchaser takes possession of any Collateral, neither the Purchaser nor any Receiver shall have any liability as a mortgagee in possession or be accountable for anything except actual receipts.

other Liens as the Purchaser may see fit, all without prejudice to the liability of Taseko to the Purchaser or the rights of the Purchaser and any Receiver under this Security Agreement.

Any Recovery received by the Purchaser in respect of the Obligations from time to time and any Recovery realized by the Purchaser on any Collateral shall be appropriated and applied by the Purchaser in accordance with Section 6.17.

6.10 Set-Off, Combination of Accounts met and/or Crossclaims

The Obligations will be paid by Taseko without regard to any equities between Taseko and the Purchaser or any right of set-off or cross-claim. Any indebtedness owing by the Purchaser to Taseko, direct or indirect, extended or renewed, actual or contingent, mutual or not, may be set off or applied against, or combined with, the Obligations by the Purchaser at any time either before or after maturity, without demand upon or notice to anyone.

6.11 Deficiency

If the proceeds of the realization of any Collateral are insufficient to repay all liquidated Obligations, Taseko shall forthwith pay or cause to be paid to the Purchaser such deficiency.

6.12 Validity of Sale

No Person dealing with the Purchaser or any Receiver or with any Representative of the Purchaser or any Receiver shall be concerned to inquire whether the Security has become enforceable, whether any right of the Purchaser or any Receiver has become exercisable, whether any Obligations remain outstanding or otherwise as to the propriety or regularity of any dealing by the Purchaser or any Receiver with any Collateral or to see to the application of any money paid to the Purchaser or any Receiver, and in the absence of fraud on the part of such Person such dealings shall be deemed, as regards such Person, to be within the rights hereby conferred and to be valid and effective accordingly.

6.13 Purchaser or Receiver may Perform

If Taseko fails to perform any Obligations, without limiting any other provision hereof, the Purchaser or any Receiver may perform those Obligations as attorney for Taseko in accordance with Section 4.6. Taseko shall remain liable under each agreement, Surface Right, Mineral Claim, Mining Lease and License to which it is party or by which it or any of its Business Assets is bound and shall perform all of its obligations thereunder, and shall not be released from any of its obligations under any such agreement, Surface Right, Mineral Claim or Mining Lease by the exercise of any rights by the Purchaser or any Receiver. Neither the Purchaser nor any Receiver shall have any obligation under any such agreement, Surface Right, Mineral Claim or Mining Lease by reason of this Security Agreement, nor shall the Purchaser or any Receiver be obliged to perform any of the obligations of Taseko thereunder or to take any action to collect or enforce any claim made subject to the security of this Security Agreement. The rights conferred on the Purchaser and any Receiver under this Security Agreement are for

the purpose of protecting the Security in the Collateral and shall not impose any obligation upon the Purchaser or any Receiver to exercise any such rights.

6.14 Effect of Appointment of Receiver

As soon as the Purchaser takes possession of any Collateral or appoints a Receiver over any Collateral, all rights of each of the Representatives of Taseko with respect to that Collateral shall cease, unless specifically continued by the written consent of the Purchaser or the Receiver.

6.15 Time for Payment

If any Obligations are due by maturity, demand or acceleration, it shall be deemed reasonable for the Purchaser to exercise its rights under this Security Agreement immediately if such payment is not made, and any days of grace or any time for payment which might otherwise be required to be afforded to Taseko by any agreement or Applicable Law is hereby irrevocably waived to the extent permitted by law.

6.16 Rights in Addition

The rights conferred by this Article 6 are in addition to, and not in substitution for, any other rights the Purchaser may have under this Security Agreement, at law, in equity or by or under Applicable Law or the Purchase Agreement or any other security agreement. The Purchaser may proceed by way of any action, suit or other proceeding at law or in equity including (a) the right to take proceedings in any court of competent jurisdiction for the sale or foreclosure of the Collateral and (b) filing proofs of claim and other documentation to establish the claims of the Purchaser in any Litigation relating to Taseko. No right of the Purchaser or any Receiver shall be exclusive of or dependent on any other. Any such right may be exercised separately or in combination, and at any time. The exercise by the Purchaser or any Receiver of any right hereunder does not preclude the Purchaser or any Receiver from further exercise of such right in accordance with this Security Agreement.

7.2 No Merger

This Security Agreement shall not operate by way of a merger of the Obligations or of any agreement or other document by which the Obligations now or at any time hereafter may be represented or evidenced. Neither the taking of any judgment nor the exercise of any power of seizure or disposition shall extinguish the liability of Taseko to pay and perform the Obligations nor shall the acceptance of any payment or alternate security constitute or create any novation.

7.3 Notices

Any notice, demand, consent, approval or other communication to be made or given under or in connection with this Security Agreement shall be given in accordance with the Purchase Agreement.

Time is and shall remain of the essence of this Security Agreement and each of its provisions.

7.5 Governing Law

This Security Agreement shall be governed by, and interpreted in accordance with, the laws in force in the Province of British Columbia, including the federal laws of Canada applicable therein (excluding any conflict of laws rule or principle which might refer such construction to the laws of another jurisdiction). Taseko irrevocably attorns to and submits to the non-exclusive jurisdiction of the Courts of British Columbia with respect to any matter arising hereunder or related hereto. Such choice of law shall, however, be without prejudice to or limitation of any other rights available to the Purchaser under the laws of any other jurisdiction where Collateral may be located.

7.6 Doctrine of Consolidation

Pursuant to section 31(2) of the Property Law Act (British Columbia), the doctrine of consolidation shall apply to this Security Agreement.

7.7 Security Effective Immediately

Neither the issuance nor registration of, or any filings with respect to, this Security Agreement, nor any partial advance of the Payment Deposit by the Purchaser, shall bind the Purchaser to advance any amounts of the Payment Deposit to Taseko, but the Security shall take effect forthwith upon the issuance of this Security Agreement by Taseko.

7.8 Entire Agreement

Agreement or other security agreements granted contemporaneously herewith by Taseko to the Purchaser and other than as may be expressed in any other written agreement entered into between Taseko and the Purchaser contemporaneously herewith. The execution of this Security Agreement has not been induced by, nor does Taseko rely upon or regard as material, any representations, warranties, conditions, other agreements or acknowledgments not expressly made in this Security Agreement and the other written agreements and other documents to be delivered pursuant hereto or contemporaneously herewith.

7.9 Provisions Reasonable

Taseko acknowledges that the provisions of this Security Agreement and, in particular, those respecting rights of the Purchaser or any Receiver against Taseko, its Business Assets and any Collateral upon a Default, are commercially reasonable and not manifestly unreasonable.

7.10 Invalidity

If any provision of this Security Agreement is found to be invalid or unenforceable, by a court of competent jurisdiction from which no further appeal right lies, that provision shall be deemed to be severed herefrom and the remaining provisions of this Security Agreement shall not be affected thereby but shall remain valid and enforceable.

7.11 Binding Effect

This Security Agreement shall enure to the benefit of the Purchaser and any Receiver and their respective successors and assigns permitted under the Purchase Agreement and shall be binding on Taseko, its legal representatives (including receivers) and its successors and assigns permitted under the Purchase Agreement. Each reference to Taseko in this Security Agreement shall be construed so as to include the successors and such permitted assigns of Taseko to the extent the context so admits.

7.12 Survival

The Obligations payable under Sections 4.10 and 6.17 (the “Indemnity Obligations”) shall survive the Payment in Full of all other Obligations and shall continue in full force and effect until Payment in Full has been irrevocably made of such Indemnity Obligations.

7.13 Statutory Waivers

To the fullest extent permitted by Applicable Law, Taseko waives all of the rights, benefits and protections given by the provisions of any existing or future statute which imposes limitations upon the rights of a secured party or upon the methods of realization of security, including any seize or xxx or anti-deficiency statute or any similar provisions of any other statute.

7.14 Currency

All references in this Security Agreement to monetary amounts, unless specifically provided, are to lawful currency of the United States of America. All sums of money payable under this Security Agreement shall be paid in the currency in which such sums are incurred or expressed as due hereunder.

7.15 Currency Conversions

If the Purchaser receives or recovers any amount payable under this Security Agreement in a currency (the “Recovered Amount”) which is different than the currency of the United States of America (the “Contract Currency”), the Purchaser may convert the Recovered Amount to the Contract Currency at the rate of exchange which the Purchaser is able, acting in a reasonable manner and in good faith, to purchase the relevant amount of the Contract Currency. The amount of the Contract Currency resulting from any such conversion shall then be applied in accordance with the provisions of Section 6.9.

7.16 Judgment Currency

If, for the purposes of obtaining or enforcing judgment in any court in any jurisdiction, it becomes necessary to convert into the currency of the country giving such judgment (the “Judgment Currency”) an amount due hereunder in a different currency (the “Agreed Currency”), then the date on which the rate of exchange for conversion is selected by the court is referred to herein as the “Conversion Date”. If there is a change in the rate of exchange between the Judgment Currency and the Agreed Currency between the Conversion Date and the actual receipt by the Purchaser or any Receiver of the amount due hereunder or under any such judgment, Taseko will, notwithstanding any such judgment, pay all such additional amounts as may be necessary to ensure that the amount received by the Purchaser or Receiver in the Judgment Currency, when converted at the rate of exchange prevailing on the date of receipt, will produce the amount due in the Agreed Currency. Taseko’s liability hereunder constitutes a separate and independent liability which shall not merge with any judgment or any partial payment or enforcement of payment of sums due under this Security Agreement.

7.17 Amendment

Subject to Section 1.5, no agreement purporting to change this Security Agreement shall be binding upon either Taseko or the Purchaser unless that agreement is in writing and signed by Taseko and the Purchaser.

7.18 Information

At any time the Purchaser may provide to any Person that claims an interest in Collateral copies of this Security Agreement or information about it or about the Collateral or the Obligations.

7.19 Date of Reference

For convenience of reference, this Security Agreement may be referred to as being dated for reference May 12, 2010 irrespective of its actual date of execution.
