All material Returns relating to, or required to be filed in connection with, any Taxes required to be filed by or on behalf of Viceroy or any subsidiary or material joint venture of Viceroy on or before the date of this Agreement have

been duly filed on a timely basis and such Returns are true, complete and correct in all material respects.

	(ii)		Each of Viceroy, its predecessors and each of their respective subsidiaries and material joint ventures, has duly and timely paid all Taxes (except to the extent immaterial, individually or in the aggregate), including all instalments on account of Taxes for the current year, that are due and payable by it on or before the date of this Agreement whether or not assessed and whether or not shown on any Return. Adequate provision has been made on the consolidated financial statements of Viceroy for amounts at least equal to the amount of all Taxes assessed and all Taxes owing by any of Viceroy, its subsidiaries or any material joint venture of Viceroy that are not yet due and payable and that relate to periods ending on or prior to the date of this Agreement, including income taxes and related deferred taxes, in conformity with GAAP and all other applicable accounting rules and principles.

	(k)		Compliance with Laws. Viceroy, its subsidiaries and its material joint ventures have complied with and are not in violation of any applicable Laws, other than non-compliance or violations which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect with respect to Viceroy, or which would not materially impair the ability of Viceroy to perform its obligations hereunder or reasonably be expected to prevent or materially delay the consummation of the Offer, any Compulsory Acquisition or any subsequent amalgamation of Yamana and Viceroy.

All such policies of insurance shall remain in force and effect (subject to taking into account insurance market conditions and offerings and industry practices) and shall not be cancelled or otherwise terminated as a result of any of the Contemplated Transactions other than such cancellations as would not individually or in the aggregate have a Material Adverse Effect with respect to Viceroy or such cancellations as have been disclosed to Yamana.

Viceroy, its material subsidiaries and its material joint ventures hold all mineral rights required to continue their respective business and operations as currently conducted and as proposed to be conducted as Disclosed Publicly, except to the extent that a failure to do so would not constitute a Material Adverse Effect with respect to Viceroy.

Since December 31, 2005, there has been no change in Yamana’s accounting policies, except as described in the notes to the Yamana Financial Statements.

	(g)		Absence of Undisclosed Liabilities. Except as disclosed in the Yamana Public Disclosure Record or the Yamana Financial Statements, neither Yamana nor any of its material subsidiaries has any material obligations or liabilities of any nature (matured or unmatured, fixed or contingent) other than liabilities incurred since June 30, 2006 in the ordinary course of business.
	(h)		No Material Adverse Effect. Except as disclosed in the Yamana Financial Statements or Yamana Public Disclosure record, since December 31, 2005 there has not been any Material Adverse Effect on Yamana.
	(i)		Tax Matters. Except as would not have a Material Adverse Effect on Yamana:

	(i)		all Returns relating to, or required to be filed in connection with, any Taxes required to be filed by or on behalf of Yamana or any material subsidiary of Yamana on or before the date of this Agreement have been duly filed on a timely basis and such Returns are true, complete and correct in all material respects.
	(ii)		each of Yamana and its material subsidiaries has duly and timely paid all Taxes (except to the extent immaterial, individually or in the aggregate), including all instalments on account of Taxes for the current year, that are due and payable by it on or before the date of this Agreement whether or not assessed and whether or not shown on any Return. Adequate provision has been made on the consolidated financial statements of Yamana for amounts at least equal to the amount of all Taxes assessed and all Taxes owing by any of Yamana or its material subsidiaries that are not yet due and payable and that relate to periods ending on or prior to the date of this Agreement, including income taxes and related deferred taxes, in conformity with GAAP and all other applicable accounting rules and principles.
	(iii)		except as disclosed to Viceroy, no deficiencies exist or have been asserted with respect to Taxes of Yamana or any material subsidiary of Yamana, neither Yamana nor any material subsidiary of Yamana is a party to any action or proceeding for assessment or collection of Taxes, nor has such event been asserted or threatened against Yamana or any material subsidiary of Yamana, or any of their respective assets.

	(j)		Compliance with Laws. Yamana and its material subsidiaries have complied with and are not in violation of any applicable Laws, other than non-compliance or violations which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect with respect to Yamana, or which would not materially impair the ability of Yamana to perform its obligations hereunder or reasonably be expected to prevent or materially delay the consummation of the Offer, any Compulsory Acquisition or any Subsequent Acquisition Transaction of Viceroy and Yamana.
	(k)		Licences, Etc. Yamana and each of its material subsidiaries owns, possesses, or has obtained and is in compliance with, all licences, permits, certificates, orders, grants and other authorizations of or from any governmental authority necessary to conduct its businesses substantially as now conducted except for where failure to do so would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect with respect to Yamana, or would not reasonably be expected to materially impair the ability of Yamana to perform its obligations hereunder or prevent or materially delay the consummation of any of the Contemplated Transactions.

	(l)		Insurance. Policies of insurance in force as of the date hereof naming Yamana as an insured adequately cover all risks reasonably and prudently foreseeable in the operation and conduct of the business of Yamana and its material subsidiaries for which, having regard to the nature of such risk and the relative cost of obtaining insurance, it is in the opinion of Yamana reasonable to seek such insurance rather than provide for self insurance. All such policies of insurance shall remain in force and effect (subject to taking into account insurance market conditions and offerings and industry practices) and shall not be cancelled or otherwise terminated as a result of any of the Contemplated Transactions other than such cancellations as would not individually or in the aggregate have a Material Adverse Effect with respect to Yamana or such cancellations as have been disclosed to Viceroy.
	(m)		Environmental. All operations of Yamana and its material subsidiaries have been and are now being conducted in compliance with all applicable Laws, including applicable Environmental Laws, except where the failure to be in compliance would not, individually or in the aggregate, have a Material Adverse Effect with respect to Yamana.

	(n)		Property and Title. Applying customary standards in the Canadian mining industry, each of Yamana and its material subsidiaries has sufficient title, clear of any title defect or Liens (other than as Disclosed Publicly), to its operating properties and properties with estimated proven and probable mineral reserves and/or estimated mineral resources (other than property to which it is lessee, in which case it has a valid leasehold interest) and has good and sufficient title to the real property interests including, without limitation, fee simple estate of and in real property, leases, easements, rights of way, permits or licences from landowners or authorities permitting the use of land by Yamana and its material subsidiaries necessary to permit the operation of their respective businesses as presently owned and conducted. Yamana and its material subsidiaries hold all mineral rights required to conduct their respective business and operations as currently conducted, except to the extent that a failure to do so would not constitute a Material Adverse Effect with respect to Yamana. All mineral rights held by Yamana and its material subsidiaries are free and clear of all Liens and royalty burdens (other than as Disclosed Publicly), and none of such mineral rights are subject to reduction by reference to mine payout or otherwise except for those created in the

5.6

Directors’ and Officers’ Insurance

     From and after the Effective Date, Yamana agrees that for the period from the Expiry Time until six years after the Expiry Time, Yamana will cause Viceroy or any successor to Viceroy to maintain Viceroy’s current directors’ and officers’ insurance policy or a policy reasonably equivalent subject in either case to terms and conditions no less advantageous to the directors and officers of Viceroy than those contained in the policy in effect on the date hereof, for all present and former directors and officers of Viceroy, covering claims made prior to or within six years after the Expiry Time.

ADDITIONAL AGREEMENTS

7.1

Non-Solicitation

     (1) Viceroy shall not, directly or indirectly, through any officer, director, employee, representative (including, for greater certainty, any financial or other advisors) or agent of Viceroy or any of its subsidiaries, take any action to (i) solicit, assist, initiate, encourage or otherwise facilitate (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) any inquiries, proposals or offers regarding, constituting or that may reasonably be expected to lead to, an Acquisition Proposal, (ii) participate in any discussions or negotiations regarding an Acquisition Proposal, (iii) withdraw, modify, or qualify or propose publicly to withdraw, modify or qualify, in a manner adverse to Yamana, the approval of the Board of Directors, or any committee thereof, of the Offer, (iv) approve, recommend or remain neutral with respect to, or propose publicly to approve or recommend, any Acquisition Proposal or (v) accept, support or enter into, or propose publicly to accept or enter into, any agreement, understanding or arrangement in respect of an Acquisition Proposal; provided that nothing contained in this Agreement shall prevent the Board of Directors from taking any of the actions described in clauses (i) through (v) above in respect of a bona fide, written Acquisition Proposal received after the date hereof that constitutes a Superior Proposal or which the Board of Directors reasonably believes could likely lead to a Superior Proposal or which is otherwise permitted under this Section 7.1.

     (2) Viceroy has notified Yamana of all Acquisition Proposals currently under consideration and shall, and shall cause the officers, directors, employees, representatives and agents of Viceroy and its subsidiaries to, immediately terminate any existing discussions or negotiations with any parties (other than Yamana) with respect to any proposal that constitutes, or may reasonably be expected to constitute, an Acquisition Proposal and in connection therewith Viceroy will discontinue access to any data rooms (virtual or otherwise) and will request (and exercise all rights it has to require) the destruction of all material including incorporating or otherwise reflecting any information regarding Viceroy and its subsidiaries. Viceroy shall not release any third party from any confidentially agreement or standstill agreement (except to allow such party to propose a Superior Proposal), and shall not waive the application of the Rights Plan in favour of any third party (except to the extent such third party makes a Superior Proposal or as otherwise required by the terms of the Rights Plan). Prior to the Effective Date, Viceroy shall confirm to Yamana that it has demanded that all third parties: (i) with whom Viceroy has discussed any Acquisitions Proposals; (ii) to whom Viceroy has delivered a confidential information memorandum regarding Viceroy; or (iii) who have otherwise received any confidential information regarding Viceroy, in each case since January 1, 2005, must either return any such confidential information or certify its destruction.

     (3) Viceroy shall promptly (and in any event within 24 hours) notify Yamana of, at first orally and then in writing, any Acquisition Proposal or written inquiry that could lead to an Acquisition

Proposal, in each case received after the date hereof of which any of its directors or officers become aware, or any amendments to the foregoing, or any request for non-public information relating to Viceroy or any of its subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records of Viceroy or any of its subsidiaries by any person that informs Viceroy or such subsidiary that it is considering making, or has made, an Acquisition Proposal and any amendment thereto and, provided Yamana agrees to such requests as to the confidentiality to be afforded in respect of such Acquisition Proposal that the person proposing the Acquisition Proposal may reasonably request, Viceroy shall provide Yamana with a written description of the material terms and conditions of any such Acquisition Proposal or inquiry, and shall provide the identity of the person making any such Acquisition Proposal or inquiry and such other details of the proposal or inquiry as Yamana may reasonably request. Viceroy shall keep Yamana (i) fully informed of the status, including any change to the material terms of any such Acquisition Proposal or inquiry; and (ii) provide Yamana with copies of all correspondence and other written material sent or provided to Viceroy from any person in connection with any Acquisition Proposal or inquiry or sent or provided by Viceroy to any person in connection with any Acquisition Proposal or inquiry immediately after receipt or delivery thereof.

     (4) If Viceroy receives a request for material non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal and the Board of Directors of Viceroy determines that such proposal would be, if consummated in accordance with its terms, a Superior Proposal or reasonably determines that such Acquisition-Proposal could likely lead to a Superior Proposal, then, and only in such case, the Board of Directors of Viceroy may, subject to the execution by such person of a confidentiality agreement having substantially the same terms as the Confidentiality Agreement, provide such person with access to information regarding Viceroy; provided, however, that the person making the Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal, and provided further that Viceroy sends a copy of any such confidentiality agreement to Yamana immediately upon its execution and Yamana is immediately provided with a list of all information provided to such person and is immediately provided with access to information similar to that which was provided to such person.

     (5) Viceroy shall ensure that its officers and directors and those of its subsidiaries and any financial or other advisors or representatives retained by it are aware of the provisions of this Section, and it shall be responsible for any breach of this Section by any such person or its advisors or representatives.

     (6) Nothing contained in this Section 7.1 shall prohibit the Board of Directors of Viceroy from withdrawing, modifying, qualifying or changing its recommendations to Viceroy Shareholders in respect of the Offer or from making any disclosure to Viceroy Shareholders prior to the Expiry Date if, in the good faith judgment of the Board of Directors, after consultation with outside counsel, such action is necessary for the Board of Directors to act in a manner consistent with its fiduciary duties or is otherwise required under applicable Laws, provided that, in the case of any proposal in respect of any such withdrawal, modification, qualification or change which does not relate to an Acquisition Proposal or a Superior Proposal and except as may be necessary for the Board of Directors to act in a manner consistent with its fiduciary duties, not less than 48 hours before the Board of Directors considers any proposal in respect of any such withdrawal, modification, qualification or change, Viceroy shall give Yamana written notice of such proposal and promptly advise Yamana of the proposed consideration of such proposal.

7.2

Right to Match

     (1) Subject to Section 7.2(2), Viceroy covenants that it will not accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Acquisition Proposal (other than a confidentiality agreement permitted by Section 7.1(4)) unless:

(a)

the Acquisition Proposal constitutes a Superior Proposal;

	(b)		Viceroy has complied with its obligations under Section 7.1 and the other provisions of this Article VII;
	(c)		Viceroy has provided Yamana with notice in writing that there is a Superior Proposal together with all documentation related to and detailing the Superior Proposal (including a copy of the confidentiality agreement between Viceroy and the person making the Superior Proposal if not previously delivered) at least four business days prior to the date on which the Board of Directors proposes to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal;
	(d)		a period (the “Response Period”) of four business days shall have elapsed from the later of the date Yamana received notice of Viceroy’s proposed determination to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal, and the date Yamana received a copy of the written proposal in respect of the Acquisition Proposal and, if Yamana has offered to amend the terms of the Offer in accordance with this Section, during such four business day period, the Board of Directors (after receiving advice from its financial advisors and outside legal counsel) shall have determined in good faith and by formal resolution that the Acquisition Proposal continues to be a Superior Proposal compared to the proposed amendment to the terms of the Offer by Yamana;
	(e)		Viceroy concurrently terminates this Agreement pursuant to Section 8.2(1)(f), and
	(f)		Viceroy has previously paid, or concurrently will pay, to Yamana the Termination Payment.

     (2) During the Response Period, Yamana will have the right, but not the obligation, to offer to amend the terms of the Offer. The Board of Directors will review, in good faith in exercise of its fiduciary duties, any such proposal by Yamana to amend the terms of the Offer, including an increase in, or modification of, the consideration to be received by the holders of Common Shares, to determine whether the Acquisition Proposal to which Yamana is responding would be a Superior Proposal when assessed against the Offer as it is proposed by Yamana to be amended. If the Board of Directors does not so determine, the Board of Directors of Viceroy will promptly reaffirm its recommendation of the Offer as amended in the same manner as described in Section 2.4. Yamana and its legal counsel shall be given a reasonable opportunity to review and comment on the form and content of any such press release prior to its issue. If the Board of Directors does so determine, Viceroy may on termination of this Agreement in accordance with Section 8.2(1)(f) and payment of the fee to Yamana pursuant to Section 7.3, approve, recommend, accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal.

     (3) Each successive amendment to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the holders of Common Shares shall constitute a new Acquisition Proposal for the purposes of this Section 7.2 and Yamana shall be afforded a new Response Period in respect of each such Acquisition Proposal.

7.3

Termination Payments

     Notwithstanding and in addition to any other provision relating to the payment of fees, including the payment of brokerage fees, if after the execution of this Agreement the Offer is not consummated because:

(a)

Yamana shall have terminated this Agreement pursuant to Section 8.2(1)(d);

	(b)		Viceroy shall have terminated this Agreement pursuant to Section 8.2(1)(f); or
	(c)		Viceroy shall have materially breached its obligations under Section 7.1 or Section 7.2,

then Viceroy shall pay to Yamana, within two business days of the first to occur of (a), (b) or (c) above, the amount of Cdn. $20.1 million in immediately available funds to an account designated by Yamana.

7.4

Access to Information; Confidentiality

     (1) From the date hereof until the earlier of the Effective Time and the termination of this Agreement, Viceroy shall, and shall cause its subsidiaries and officers, directors, employees, independent auditors, accounting advisers and agents to, afford Yamana and to its officers, employees, agents and representatives of the other Party such access as may reasonably be required at all reasonable times, including for the purpose of facilitating integration business planning, to Viceroy’s officers, employees, agents, properties, books, records and Contracts, and shall furnish Yamana with all data and information as may reasonably be requested. Yamana and Viceroy acknowledge and agree that information furnished pursuant to this Section shall be subject to the terms and conditions of the Confidentiality Agreement.

     (2) Yamana and Viceroy acknowledge that information received pursuant to Section 7.4 may be personal information under applicable Laws, or non-public or proprietary in nature and therefore all such information shall be deemed to be “Confidential Information” for purposes of the Confidentiality Agreement. Yamana and Viceroy further acknowledge their obligation to maintain the confidentiality of such Confidential Information in accordance with the Confidentiality Agreement. If any material is withheld by Viceroy or Yamana or any of their subsidiaries (the “Disclosing Party”) because of the confidential nature of such material, or otherwise, the Disclosing Party or such subsidiary shall inform the other (the “Receiving Party”) as to the general nature of what is being withheld and such information may, in the sole discretion of the Disclosing Party, be disclosed to external advisors of the Receiving Party.

     (3) Without limiting the generality of Sections 7.4(1) and (2) above, until the Mailing Date, each party shall make available to the other such information, documentation and access to personnel and advisors to allow the offer to conduct confirmatory due diligence with respect to corporate, financial, legal and title due diligence. The purpose of such due diligence shall be solely to permit each party to confirm the accuracy in all material respects of representations and warranties, the material compliance with all covenants and the absence of any undisclosed fact which would have a Material Adverse Effect on the other party.

7.5

Alternative Transaction

     Viceroy agrees to cooperate in good faith with Yamana and to take all reasonable steps and actions to assist Yamana to complete the Offer as promptly as practicable. In addition, in the event that Yamana concludes that it is necessary or desirable to proceed with another form of transaction (such as a plan of arrangement or amalgamation) whereby Yamana or its affiliates would effectively acquire all of the Common Shares within the same time periods and on economic terms having consequences to the Viceroy Shareholder that are equivalent to or better than those contemplated by this Agreement (an “Alternative Transaction”), Viceroy agrees to support the completion of such Alternative Transaction in the same manner as the Offer and shall otherwise fulfill its covenants contained in this Agreement in respect of such Alternative Transaction.
