2.12

U.S. Tax Matters

The Arrangement is intended to qualify as a reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Code and this Agreement and the Plan of Arrangement are intended to be a “plan of reorganization” within the meaning of the Treasury Regulations promulgated under Section 368 of the Code for purposes of Sections 354 and 361 of the Code. Each party hereto shall treat the Arrangement as a reorganization within the meaning of Section 368(a) of the Code for all U.S. federal income tax purposes, and shall treat this Agreement and the Plan of Arrangement as a “plan of reorganization” within the meaning of the U.S. Treasury Regulations promulgated under Section 368 of the Code, and shall not take any position on any Return or otherwise take any Tax reporting position inconsistent with such treatment, unless otherwise required by a “determination” within the meaning of Section 1313 of the Code that such treatment is not correct. Each Party hereto shall act in a manner that is consistent with the Parties’ intention that the Arrangement be treated as a reorganization within the meaning of Section 368(a) of the Code for all U.S. federal income tax purposes, and shall not take any action, or knowingly fail to take any action, if such action or failure to act would reasonably be expected to prevent the Arrangement from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

2.15

Withholding Taxes

Rio Alto, Tahoe and the Depositary will be entitled to deduct and withhold from any consideration otherwise payable to any Rio Alto Shareholder under the Plan of Arrangement (including any payment to Dissenting Rio Alto Shareholders) such amounts as Rio Alto, Tahoe or the Depositary is required to deduct and withhold with respect to such payment under the Tax Act, the Code, and the rules and regulations promulgated thereunder, or any provision of any provincial, state, local or foreign tax Law as counsel may advise is required to be so deducted and withheld by Rio Alto, Tahoe or the Depositary, as the case may be. For the purposes hereof, all such withheld amounts shall be treated as having been paid to the person in respect of which such deduction and withholding was made on account of the obligation to make payment to such person hereunder, provided that such deducted or withheld amounts are actually remitted to the appropriate Governmental Authority by or on behalf of Rio Alto, Tahoe or the Depositary, as the case may be. To the extent necessary, such deductions and withholdings may be effected by selling any Rio Alto Shares to which any such person may otherwise be entitled under the Plan of Arrangement, and any amount remaining following the sale, deduction and remittance shall be paid to the person entitled thereto as soon as reasonably practicable.

(f) Notwithstanding Section 5.1, in the event Rio Alto receives a bona fide Acquisition Proposal that is a Superior Proposal from any person after the date hereof and prior to the Rio Alto Meeting, then the Rio Alto Board may, prior to the Rio Alto Meeting, withdraw, modify, qualify or change in a manner adverse to Tahoe its approval or recommendation of the Arrangement and/or approve or recommend such Superior Proposal or enter into an Acquisition Agreement with respect to such Superior Proposal but only if:

	(vi)	Rio Alto has previously, or concurrently will have, paid to Tahoe the Termination Fee.

(g) The Rio Alto Board will review in good faith any offer made by Tahoe to amend the terms of this Agreement and the Arrangement in order to determine, in consultation with its financial advisors and outside legal counsel, whether the proposed amendments would, upon acceptance, result in the Acquisition Proposal previously constituting a Superior Proposal ceasing to be a Superior Proposal. Rio Alto agrees that, subject to Rio Alto’;s disclosure obligations under applicable Securities Laws, the fact of the making of, and each of the terms of, any such proposed amendments shall be kept strictly confidential and shall not be disclosed to any person (including without limitation, the person having made the Superior Proposal), other than Rio Alto’;s Representatives, without Tahoe’;s prior written consent. If the Rio Alto Board determines that such Acquisition Proposal would cease to be a Superior Proposal as a result of the amendments proposed by Tahoe, Rio Alto will forthwith so advise Tahoe and will promptly thereafter accept the offer by Tahoe to amend the terms of this Agreement and the Arrangement and the Parties agree to take such actions and execute such documents as are necessary to give effect to the foregoing. If the Rio Alto Board continues to believe in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal remains a Superior Proposal and therefore rejects Tahoe’;s offer to amend this Agreement and the Arrangement, if any, Rio Alto may, subject to compliance with the other provisions hereof, terminate this Agreement in accordance with Section 6.1(d)(i) to enter into an Acquisition Agreement in respect of such Superior Proposal.

(h) Each successive modification of any Superior Proposal shall constitute a new Superior Proposal for the purposes of Section 5.1(f) and shall require a new five full Business Day Superior Proposal Notice Period from the date described in Section 5.1(f)(ii) with respect to such new Superior Proposal. If the Rio Alto Meeting is scheduled to occur during a Superior Proposal Notice Period, upon the request of Tahoe, Rio Alto shall, adjourn or postpone the Rio Alto Meeting to (i) a date specified by Tahoe that is not later than six Business Days after the date on which the Rio Alto Meeting was originally scheduled to be held, or (ii) if Tahoe does not specify such date to the sixth day after the date on which the Rio Alto Meeting was originally scheduled to be held.

(i) The Rio Alto Board shall reaffirm its recommendation in favour of the Arrangement by news release promptly after (A) the Rio Alto Board has determined that any Acquisition Proposal is not a Superior Proposal if the Acquisition Proposal has been publicly announced or made; or (B) the Rio Alto Board makes the determination referred to in Section 5.1(g) that an Acquisition Proposal that has been publicly announced or made and which previously constituted a Superior Proposal has ceased to be a Superior Proposal. Tahoe shall be given a reasonable opportunity to review and comment on the form and content of any such news release. Such news release shall state that the Rio Alto Board has determined that such Acquisition Proposal is not a Superior Proposal.

(j) Rio Alto will not become a party to any Contract with any person subsequent to the date hereof that limits or prohibits Rio Alto from (x) providing or making available to Tahoe and its affiliates and Representatives any information provided or made available to such person or its officers, directors, employees, consultants, advisors, agents or other representatives (including solicitors, accountants, investment bankers and financial advisors) pursuant to any confidentiality agreement described in this Section 5.1 or (y) providing Tahoe and its affiliates and Representatives with any other information required to be given to it by Rio Alto under this Section 5.1

(k) Rio Alto agrees (i) not to release any persons from, or terminate, modify, amend or waive the terms of, any confidentiality agreement or standstill agreement or standstill provisions in any such confidentiality agreement that Rio Alto entered into prior to the date hereof, (ii) to promptly and diligently enforce all standstill, non-disclosure, non-disturbance, non-solicitation and similar covenants that it has entered into prior to the date hereof or enter into after the date hereof (it being acknowledged and agreed that the automatic termination of any standstill provisions of any such agreement as the result of entering into and announcement of this Agreement shall not be a violation of this Section 5.1(k)) . Rio Alto shall forthwith, if provided for in a confidentiality agreement with such person, request the return or destruction of all information provided to any third party that, has entered into a confidentiality agreement with Rio Alto to the extent that such information has not previously been returned or destroyed, and shall use all commercially reasonable efforts to ensure that such requests are honoured.

(l) Notwithstanding any of the provisions of this Section 5.1, the Rio Alto Board shall have the right to respond, within the time and in the manner required by applicable Securities Laws, to any take-over bid or tender or exchange offer made for the Rio Alto Shares that it determines is not a Superior Proposal.

(m) Rio Alto shall ensure that its Representatives are aware of the provisions of this Section 5.1, and Rio Alto shall be responsible for any breach of this Section 5.1 by any of its Representatives.

5.2

(A)

either Rio Alto or Tahoe shall have exercised its respective termination right under Section 6.1(b)(i) or Section 6.1(b)(ii), and

(B)

Rio Alto shall have (x) completed any Acquisition Proposal within twelve months after this Agreement is terminated or (y) entered into an Acquisition Agreement in respect of any Acquisition Proposal or the Rio Alto Board shall have recommended any Acquisition Proposal, in each case, within twelve months after this Agreement is terminated, which Acquisition Proposal in either case, as it may be modified or amended, is subsequently completed (whether before or after the expiry of such twelve -month period);

provided, however, that for the purposes of this Section 5.2(a)(i) all references to 20% in the definition of Acquisition Proposal shall be changed to 50%;

	(ii)	this Agreement shall have been terminated by Tahoe pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii); or

	(iii)	this Agreement shall have been terminated by Tahoe pursuant to Section 6.1(c)(iii) or Section 6.1(c)(vi) and Rio Alto shall have (x) completed any Acquisition Proposal within twelve months after this Agreement is terminated or (y) entered into an Acquisition Agreement in respect of any Acquisition Proposal or the Rio Alto Board shall have recommended any Acquisition Proposal, in each case, within twelve months after this Agreement is terminated, which Acquisition Proposal in either case, as it may be modified or amended, is subsequently completed (whether before or after the expiry of such twelve month period); and

	(iv)	this Agreement shall have been terminated by Rio Alto pursuant to Section 6.1(d)(i) .

(b) If a Termination Fee Event occurs, Rio Alto shall pay to Tahoe a termination fee of $57.6 million (the “Termination Fee) by wire transfer in immediately available funds to an account specified by Tahoe. Rio Alto shall pay the Termination Fee to Tahoe on or prior to completion of the applicable Acquisition Proposal (in the case of a Termination Fee Event referred to in Section 5.2(a)(i) or 5.2(a)(iii), within one Business Day following termination of this Agreement (in the case of a Termination Fee Event referred to in Section 5.2(a)(ii)), or prior to or concurrent with termination of this Agreement (in the case of a Termination Fee Event referred to in Section 5.2(a)(iv)) . If Rio Alto does not have sufficient financial resources to pay the Termination Fee, then it shall be a condition of (i) any Superior Proposal referred to in Section 6.1(d)(i), and (ii) any share or asset acquisition referred to in Section 5.2(a)(i)(B) or Section 5.2(a)(iii) where Rio Alto has entered into any agreement to support such share acquisition or to transfer such assets, as applicable, that the person making such Superior Proposal or acquisition, as applicable, shall advance or otherwise provide to Rio Alto the cash required for Rio Alto to pay the Termination Fee, which amount shall be so advanced or provided prior to the date on which Rio Alto is required to pay the Termination Fee. Tahoe acknowledges that in no event shall Rio Alto be obligated to pay more than one Termination Fee pursuant to this Section 5.2.

(c) Except as otherwise specified herein, each Party will pay its respective legal and accounting costs, fees and expenses incurred in connection with the preparation, execution and delivery of this Agreement and all documents and instruments executed pursuant to this Agreement and any other costs, fees and expenses whatsoever and howsoever incurred, and will indemnify and save harmless the others from and against any claim for any broker’s, finder’s or placement fee or commission alleged to have been incurred as a result of any action by it in connection with the transactions hereunder, except in the event this Agreement is terminated in connection with a Termination Fee Event, then Rio Alto shall promptly, but in no event later than the payment by Rio Alto of the Termination Fee, pay the reasonable costs, fees and expenses actually incurred by Tahoe in connection with the negotiation of this Agreement and the transactions contemplated hereby to a maximum amount of $2,500,000 as reimbursement to Tahoe payable by wire transfer in immediately available funds to an account specified by Tahoe.

(d) Each Party acknowledges that all of the payment amounts set out in this Section 5.2 are payments in consideration for the disposition of Tahoe’;s rights under this Agreement and represent liquidated damages which are a genuine pre-estimate of the damages which Tahoe will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement and are not penalties. Rio Alto irrevocably waives any right that it may have to raise as a defence that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that the payment of an amount pursuant to this Section 5.2 in the manner provided herein is the sole and exclusive remedy of Tahoe in respect of the event giving rise to such payment, provided, however, that nothing contained in this Section 5.2, and no payment of any such amount, shall relieve or have the effect of relieving Rio Alto in any way from liability for damages incurred or suffered by Tahoe as a result of an intentional or wilful breach of this Agreement, including the intentional or wilful making of a misrepresentation in this Agreement and nothing contained in this Section 5.2 shall preclude Rio Alto from seeking injunctive relief in accordance with Section 8.13 to restrain the breach or threatened breach of the covenants or agreements set forth in this Agreement or the Confidentiality Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith.

Article 3
ARRANGEMENT

3.1	The Arrangement

Commencing at the Effective Time, each of the events set out below shall occur and be deemed to occur in the following sequence, in each case without any further authorization, act or formality of or by Rio Alto, Tahoe or any other person:

	(a)	the rights issued under the Rio Alto Shareholder Rights Plan shall be cancelled, without any payment or other consideration to the Rio Alto Shareholders, and the Rio Alto Shareholder Rights Plan shall terminate and cease to have any further force or effect;

	(b)	Following the step in Section 3.1(a):

	(i)	each Rio Alto Share held by a Dissenting Rio Alto Shareholder shall be deemed to be transferred by the holder thereof, without any further act or formality on its part, free and clear of all liens, claims and encumbrances, to Tahoe and Tahoe shall thereupon be obliged to pay the amount therefor determined and payable in accordance with Article 4 hereof, and the name of such holder shall be removed from the central securities register of Rio Alto as a holder of Rio Alto Shares and Tahoe shall be recorded as the registered holder of the Rio Alto Shares so transferred and shall be deemed to be the legal owner of such Rio Alto Shares;

	(ii)	each issued Rio Alto Share held by a Former Rio Alto Shareholder (other than a Dissenting Rio Alto Shareholder or Tahoe or any subsidiary of Tahoe) shall be transferred to Tahoe (free and clear of any Liens) and in consideration therefor Tahoe shall issue Tahoe Shares on the basis of 0.227 of a fully paid and non- assessable Tahoe Share and $0.001 in cash for each Rio Alto Share, subject to Section 3.3 and Article 5 hereof;

A-7

(iii)

at the same time as the steps in Sections 3.1(b)(i) and 3.1(b)(ii), with respect to each Rio Alto Share,

	A.	the holder thereof will cease to be the holder thereof or to have any rights as a holder in respect of such Rio Alto Share and the name of the holder thereof will be removed from the central securities register of Rio Alto with respect to such Rio Alto Share;

	B.	legal and beneficial title to such Rio Alto Share will vest in Tahoe and Tahoe will be and be deemed to be the transferee and legal and beneficial owner of such Rio Alto Share (free and clear of any Liens) and will be entered in the central securities register of Rio Alto as the sole holder thereof;

	(iv)	all Rio Alto Options shall vest and in accordance with the terms of the Rio Alto Options, each outstanding Rio Alto Option shall, without any further action on the part of any holder of a Rio Alto Option, be deemed to have been exchanged for an option entitling the holder to receive, upon the due exercise of such Rio Alto Option (including without limitation, payment of the exercise price thereof), in lieu of Rio Alto Shares to which such holder was theretofore entitled upon such exercise, the number of Tahoe Shares equal to the product of: (A) the number of Rio Alto Shares subject to the Rio Alto Option immediately before the Effective Time, and (B) 0.227 plus the portion of a Tahoe Share that, immediately prior to the Effective Time, has a fair market value equal to $0.001 cash, provided that if the foregoing would result in the issuance of a fraction of a Tahoe Share on any particular exercise of a Rio Alto Option, then the number of Tahoe Shares otherwise issued shall be rounded down to the nearest whole number of Tahoe Shares. The exercise price per Tahoe Share subject to any such Rio Alto Option shall be an amount equal to the quotient of (A) the exercise price per Rio Alto Share subject to such Rio Alto Option immediately prior to the Effective Time divided by (B) 0.227 plus such portion of a Tahoe Share that, immediately prior to the Effective Time, has a fair market value equal to $0.001 cash (provided that the aggregate exercise price payable on any particular exercise of Rio Alto Options shall be rounded up to the nearest whole cent). Subject to the foregoing, each Rio Alto Option shall continue to be governed by and be subject to the terms of the Rio Alto Option Plan, subject to any supplemental exercise documents issued by Tahoe to holders of Rio Alto Options to facilitate the exercise of the Rio Alto Option and the payment of the corresponding portion of the exercise price with each of them. Each Rio Alto Option will remain exercisable for a period of one year from the date on which the holder of such options with Rio Alto is terminated in connection with the Arrangement, being the exercise period provided for in the Rio Alto Option Plan;

		If the adjustment to the Rio Alto Options contemplated by this paragraph results in a disposition of Rio Alto Options for options to acquire Tahoe Shares or “new” Rio Alto Options, it is intended that the provisions of subsection 7(1.4) of the Tax Act apply to any such disposition. Therefore, in the event that the Tahoe Option In-The-Money Amount in respect of a Rio Alto Option exceeds Rio Alto Option In- The-Money Amount in respect of the Rio Alto Option, the number of Tahoe Shares which may be acquired on exercise of the Rio Alto Option at and after the Effective Time will be adjusted accordingly with effect at and from the Effective Time to ensure that the Tahoe Option In-The-Money Amount in respect of the Rio Alto Option does not exceed Rio Alto Option In-The-Money Amount in respect of the Rio Alto Option and the ratio of the amount payable to acquire such shares to the value of such shares to be acquired shall be unchanged;

A-8

(v)

in accordance with the terms of the SGC Options, each outstanding SGC Option shall, without any further action on the part of any holder of an SGC Option, be deemed to have been exchanged for an option entitling the holder to receive, upon the due exercise of such SGC Option (including without limitation, payment of the exercise price thereof), in lieu of Rio Alto Shares to which such holder was theretofore entitled upon such exercise, the number of Tahoe Shares equal to the product of: (A) the number of Rio Alto Shares subject to the SGC Option immediately before the Effective Time, and (B) 0.227 plus the portion of a Tahoe Share that, immediately prior to the Effective Time, has a fair market value equal to $0.001 cash, provided that if the foregoing would result in the issuance of a fraction of a Tahoe Share on any particular exercise of a SGC Option, then the number of Tahoe Shares otherwise issued shall be rounded down to the nearest whole number of Tahoe Shares. The exercise price per Tahoe Share subject to any such SGC Option shall be an amount equal to the quotient of (A) the exercise price per Rio Alto Share subject to such SGC Option immediately prior to the Effective Time divided by (B) 0.227 plus such portion of a Tahoe Share that, immediately prior to the Effective Time, has a fair market value equal to $0.001 cash (provided that the aggregate exercise price payable on any particular exercise of SGC Options shall be rounded up to the nearest whole cent). Subject to the foregoing, each SGC Option shall continue to be governed by and be subject to the terms of the SGC Option Plan, subject to any supplemental exercise documents issued by Tahoe to holders of SGC Options to facilitate the exercise of the SGC Option and the payment of the corresponding portion of the exercise price with each of them.

A-9

		If the adjustment to the SGC Options contemplated by this paragraph results in a disposition of SGC Options for options to acquire Tahoe Shares or “new” SGC Options, it is intended that the provisions of subsection 7(1.4) of the Tax Act apply to any such disposition. Therefore, in the event that the Tahoe Option In-The-Money Amount in respect of a SGC Option exceeds SGC Option In- The-Money Amount in respect of the SGC Option, the number of Tahoe Shares which may be acquired on exercise of the SGC Option at and after the Effective Time will be adjusted accordingly with effect at and from the Effective Time to ensure that the Tahoe Option In-The-Money Amount in respect of the SGC Option does not exceed SGC Option In-The-Money Amount in respect of the SGC Option and the ratio of the amount payable to acquire such shares to the value of such shares to be acquired shall be unchanged; and

	(vi)	each holder of each Rio Alto Option, SGC Option and Rio Alto Share, with respect to each step set out above applicable to such holder, shall be deemed, at the time such step occurs, to have executed and delivered all consents, releases, assignments and waivers, statutory or otherwise, required to transfer such Rio Alto Option, SGC Option and Rio Alto Share, as the case may be, in accordance with such step;

	(vii)	each Rio Alto Share held by Tahoe shall be transferred to Subco in consideration of the issue by Subco to Tahoe of one common share of Subco for each Rio Alto Share so transferred, and the amount added to the stated capital of the Subco common shares will be equal to the paid up capital (as such term is defined in the Tax Act) of the Rio Alto Shares so transferred;

	(viii)	the stated capital in respect of the Rio Alto Shares shall be reduced to $1.00 without any repayment of capital in respect thereof;

	(ix)	Rio Alto will file an election with the CRA to cease to be a public corporation for the purposes of the Tax Act;

	(x)	Rio Alto and Subco shall amalgamate to continue as one corporation (“Amalco”) under Section 184(1) of the ABCA;

	(xi)	from and after the Effective Date:

	A.	Amalco will continue to be liable for all of the liabilities and obligations of Rio Alto and Subco;

	B.	all rights, contracts, permits and interests of Rio Alto and Subco will continue as rights, contracts, permits and interests of Amalco as if Rio Alto and Subco continued and, for greater certainty, the amalgamation will not constitute a transfer or assignment of the rights or obligations of either of Rio Alto or Subco under any such rights, contacts, permits and interests;

A-10

	C.	any existing cause of action, claim or liability prosecution will be unaffected;

	D.	a civil, criminal or administrative action or proceeding pending by or against either Subco or Rio Alto may be continued by or against Amalco;

	F.	the name of Amalco shall be “Rio Alto Mining Limited”;

The Arrangement is intended to qualify as a reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Code and this Plan of Agreement and the Arrangement Agreement are intended to be a “plan of reorganization” within the meaning of the Treasury Regulations promulgated under Section 368 of the Code for purposes of Sections 354 and 361 of the Code.

Article 4
WARRANTS

4.1	Rio Alto Warrants

In accordance with the terms of the Rio Alto Warrants, each holder of a Rio Alto Warrant shall be entitled to receive (and such holder shall accept) upon the exercise of such holder's Rio Alto Warrant, in lieu of Rio Alto Shares to which such holder was theretofore entitled upon such exercise, and for the same aggregate consideration payable therefor, the number of Tahoe Shares and cash which the holder would have been entitled to receive as a result of the transactions contemplated by this Arrangement if, immediately prior to the Effective Date, such holder had been the registered holder of the number of Rio Alto Shares to which such holder would have been entitled if such holder had exercised such holder's Rio Alto Warrants immediately prior to the Effective Time. Each Rio Alto Warrant shall continue to be governed by and be subject to the terms of the applicable Rio Alto Warrant certificate, subject to any supplemental exercise documents issued by Tahoe to holders of Rio Alto Warrants to facilitate the exercise of the Warrants and the payment of the corresponding portion of the exercise price with each them.

Article 5
DISSENT RIGHTS

5.1	Rights of Dissent

Pursuant to the Interim Order, each registered Rio Alto Shareholder may exercise rights of dissent (“Dissent Rights”) under Section 191 of the ABCA as modified by this Article 6 as the same may be modified by the Interim Order or the Final Order in respect of the Arrangement, provided that the written objection to the Arrangement Resolution contemplated by Section 191 of the ABCA must be sent to and received by Rio Alto at or before the Rio Alto Meeting or any date to which the Rio Alto Meeting may be postponed or adjourned. Rio Alto Shareholders who duly exercise such rights of dissent and who: (a) are ultimately determined to be entitled to be paid fair value from Tahoe, for the Dissenting Shares in respect of which they have exercised Dissent Rights, will be deemed to have irrevocably transferred such Dissenting Shares to Tahoe pursuant to Section 3.1(b)(i) in consideration of such fair value; or (b) are ultimately not entitled, for any reason, to be paid fair value for the Dissenting Shares in respect of which they have exercised Dissent Rights, will be deemed to have participated in the Arrangement on the same basis as a Rio Alto Shareholder who has not exercised Dissent Rights, as at and from the time specified in Section 3.1(b)(i), and be entitled to receive only the consideration set forth in Section 3.1(b)(ii);

but in no case will Rio Alto or Tahoe or any other person be required to recognize such holders as holders of Rio Alto Shares after the completion of the steps set forth in Section 3.1(b), and each Dissenting Rio Alto Shareholder will cease to be entitled to the rights of a Rio Alto Shareholder in respect of the Rio Alto Shares in relation to which such Dissenting Rio Alto Shareholder has exercised Dissent Rights and the central securities register of Rio Alto will be amended to reflect that such former holder is no longer the holder of such Rio Alto Shares as and from the completion of the steps in Section 3.1(b) .
