2.14	U.S. Tax Matters

Pan American, Acquireco and Minefinders intend to adopt this Agreement as a “plan of reorganization” within the meaning of Treasury Regulation section 1.368-2(g) and to treat Pan American’s acquisition of Minefinders as a “reorganization” within the meaning of section 368(a) of the Code. To that end, it is acknowledged that the exchange of Minefinders Shares for the Consideration pursuant to this Agreement and the Plan of Arrangement, the transfer of the Minefinders Shares to Acquireco, and the amalgamation of Acquireco and Minefinders with Minefinders surviving, are interdependent steps in a single transaction, to which the Parties hereto are legally committed as provided herein, and which may be fairly characterized as a tax-deferred “reorganization” within the meaning of section 368(a) of the Code. Both Parties agree to treat the Arrangement as a reorganization within the meaning of Section 368(a) of the Code for all United States federal income tax purposes, and to not take any position on any Tax 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. The Parties agree to 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 United States federal income tax purposes. Notwithstanding the foregoing, Pan American and Minefinders make no representation, warranty or covenant to each other, to any Minefinders Shareholder, or any holder of securities of Minefinders (including without limitation any holder of Minefinders Options and Minefinders Convertible Notes) regarding the U.S. federal income tax consequences of the transactions contemplated by this Agreement to Minefinders, any Minefinders Shareholder, or any holder of securities of Minefinders.

- 24 -

(b) Fairness Opinion and Recommendation. As of the date hereof:

(ii) the Minefinders Board has determined, after receiving financial and legal advice, that the Arrangement is fair to Minefinders Shareholders (other than Pan American and its affiliates) and that the Arrangement is in the best interests of Minefinders, and the Minefinders Board has resolved to recommend that the Minefinders Shareholders and holders of Minefinders Options vote in favour of the Arrangement Resolution.

This Agreement has been duly executed and delivered by Minefinders and constitutes a valid and binding obligation of Minefinders, enforceable by Pan American against Minefinders in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency and other applicable Laws affecting the enforcement of creditors’ rights generally and subject to the qualification that equitable remedies may be granted only in the discretion of a court of competent jurisdiction.

ADDITIONAL AGREEMENTS

7.1	Minefinders Non-Solicitation

(ii) engage in any discussions or negotiations regarding, or provide any information with respect to, or otherwise co-operate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any other Person to make or complete any Acquisition Proposal for Minefinders, provided, however, that, for greater certainty, Minefinders may advise any Person making an unsolicited Acquisition Proposal for Minefinders that such Acquisition Proposal does not constitute a Superior Proposal when the Minefinders Board has so determined;

(iii) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in any manner adverse to Pan American, the recommendation of the Minefinders Board or any committee thereof of the Arrangement Resolution;

(iv) approve, recommend or remain neutral with respect to, or propose publicly to approve, recommend or remain neutral with respect to, any Acquisition Proposal for Minefinders (it being understood that publicly taking no position or a neutral position with respect to an Acquisition Proposal for a period

- 72 -

of five (5) business days following the public announcement of such Acquisition Proposal or (B) in respect of which no public announcement has been made and a confidentiality agreement has been executed in accordance with Subsection 7.1(d), shall not be considered a violation of this Subsection 7.1(a)(iv); or

(v) accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, arrangement or undertaking related to any Acquisition Proposal for Minefinders,

provided, however, that nothing contained in this Subsection 7.1(a) or any other provision of this Agreement shall prevent Minefinders from, and Minefinders shall be permitted to engage in discussions or negotiations with, or respond to enquiries from any Person that has made an unsolicited written Acquisition Proposal for Minefinders that the Minefinders Board has determined constitutes or could reasonably be expected to result in a Superior Proposal, or provide information and access to properties, facilities, books or records of Minefinders pursuant to Subsection 7.1(d) to any Person where the requirements of that Subsection are met.

(b) Minefinders shall immediately cease and cause to be terminated any existing discussions or negotiations with any Person (other than Pan American) with respect to any potential Acquisition Proposal and, in connection therewith, Minefinders will discontinue access to any of its confidential information (and not establish or allow access to any of its confidential information, or any data room, virtual or otherwise) and shall as soon as possible request the return or destruction of all confidential information provided within two (2) years prior to the date of this Agreement in connection therewith to the extent such information has not already been returned or destroyed. Minefinders agrees not to release any third party from any confidentiality, non-solicitation or standstill agreement to which such third party is a party (except as required under any such agreement), or terminate, modify, amend or waive the terms thereof and Minefinders undertakes to enforce, or cause its Subsidiaries to enforce, all standstill, non-disclosure, non-disturbance, non-solicitation and similar covenants that it or any of its Subsidiaries have entered into prior to the date hereof or entered into after the date hereof.

Such notice to Pan American shall be made, from time to time, first immediately orally and then promptly (and in any event within 24 hours) in writing and shall indicate the identity of the Person making such proposal, inquiry or contact, all material terms thereof and such other details of the proposal, inquiry or contact known to Minefinders, and shall include copies of any such proposal, inquiry, offer or request or any amendment to any of the foregoing. Minefinders shall keep Pan American promptly and fully informed of the status, including any change to the material terms, of any such Acquisition Proposal, offer, inquiry or request and will respond promptly to all inquiries by Pan American with respect thereto.

- 73 -

(d) If Minefinders receives a request for material non-public information from a Person who proposes to Minefinders an unsolicited written Acquisition Proposal and: (x) the Minefinders Board determines that such Acquisition Proposal constitutes or could reasonably be expected to result in a Superior Proposal; and (y) in the opinion of the Minefinders Board, acting in good faith and on advice from its outside legal advisors, the failure to provide such party with access to information regarding Minefinders and its Subsidiaries would be inconsistent with the fiduciary duties of the Minefinders Board, then, and only in such case, Minefinders may provide such Person with access to information regarding Minefinders and its Subsidiaries, subject to the execution of a confidentiality and standstill agreement which is customary in such situations and which, in any event and taken as a whole, is no less favourable to Minefinders than the Confidentiality Agreement; provided that Minefinders sends a copy of any such confidentiality and standstill agreement to Pan American promptly upon its execution and Pan American is provided with a list of, and, at the request of Pan American, copies of, the information provided to such Person and immediately provided with access to similar information to which such Person was provided.

(e) Minefinders agrees that it will not accept, approve or enter into any agreement (a “Proposed Minefinders Agreement”), other than a confidentiality agreement as contemplated by Subsection 7.1(d), with any Person providing for or to facilitate any Acquisition Proposal for Minefinders unless:

(ii) the Minefinders Meeting has not occurred;

(iii) Minefinders has complied with Subsections 7.1(a) through 7.1(d) inclusive;

(iv) Minefinders has provided Pan American with a notice in writing that there is a Superior Proposal for Minefinders together with all documentation related to and detailing the Superior Proposal, including a copy of any Proposed Minefinders Agreement relating to such Superior Proposal, and a written notice from the Minefinders Board regarding the value in financial terms that the Minefinders Board has in consultation with its financial advisors determined should be ascribed to any non-cash consideration offered under the Superior Proposal, such documents to be so provided to Pan American not less than five (5) business days prior to the proposed acceptance, approval, recommendation or execution of the Proposed Minefinders Agreement by Minefinders;

(v) five (5) business days shall have elapsed from the date Pan American received the notice and documentation referred to in Subsection 7.1(e)(iv) from Minefinders (the “Response Period”) and, if Pan American has proposed to amend the terms of the Arrangement in accordance with Subsection 7.1(f), the Minefinders Board shall have determined, in good faith, after consultation with its financial advisors and outside legal counsel, that the Acquisition Proposal for Minefinders is a Superior Proposal compared to the proposed amendment to the terms of the Arrangement by Pan American;

(vi) Minefinders concurrently terminates this Agreement pursuant to Subsection 8.2(a)(iv)(C); and

- 74 -

(vii) Minefinders has previously, or concurrently will have, paid to Pan American the Minefinders Termination Payment,

and Minefinders further agrees that it will not withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to Pan American the recommendation of the Arrangement Resolution, nor accept, approve or recommend any Acquisition Proposal unless the requirements of this Subsection 7.1(e)(i) through Subsection 7.1(e)(vii) have been satisfied or pursuant to Subsection 7.1(h).

(f) Minefinders acknowledges and agrees that, during the Response Period, or such longer period as Minefinders may approve (in its sole and absolute discretion) for such purpose, Pan American shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement and Minefinders shall co-operate with Pan American with respect thereto, including negotiating in good faith with Pan American during the Response Period. The Minefinders Board will review any proposal received from Pan American during the Response Period to amend the terms of this Agreement in order to determine, in good faith in the exercise of its fiduciary duties, whether Pan American’s proposal to amend this Agreement would result in the Acquisition Proposal for Minefinders ceasing to be a Superior Proposal compared to the proposed amendment to the terms of this Agreement. If the Minefinders Board determines that the Acquisition Proposal for Minefinders would thereby cease to be a Superior Proposal, it will cause Minefinders to enter into an amendment to this Agreement reflecting the offer by Pan American to amend the terms of the Agreement and will further agree not to enter into the applicable Proposed Minefinders Agreement.

(g) The Minefinders Board shall promptly reaffirm its recommendation of the Arrangement Resolution by press release after: (x) any Acquisition Proposal for Minefinders which the Minefinders Board determines not to be a Superior Proposal is publicly announced or made; or (y) the Minefinders Board determines that a proposed amendment to the terms of the Agreement would result in an Acquisition Proposal for Minefinders which has been publicly announced or made ceasing to be a Superior Proposal, and Pan American has so amended the terms of the Arrangement. Pan American and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such press release, recognizing that whether or not such comments are appropriate will be determined by Minefinders, acting reasonably.

(h) Nothing in this Agreement shall:

(i) prohibit the Minefinders Board from withdrawing, modifying, or qualifying, or failing to reaffirm publicly, its recommendation of the Arrangement Resolution as a result of a Pan American Material Adverse Effect; or

(ii) prevent the Minefinders Board from responding through a directors’ circular or otherwise as required by applicable Securities Laws to an Acquisition Proposal for Minefinders that it determines is not a Superior Proposal. Further, nothing in this Agreement shall prevent the Minefinders Board from making any disclosure to the securityholders of Minefinders if the Minefinders Board, acting in good faith and upon the advice of its legal advisors, shall have first determined that the failure to make such disclosure would be inconsistent with the fiduciary duties of the Minefinders Board or such disclosure is otherwise required under

- 75 -

applicable Law; provided, however, that, notwithstanding the Minefinders Board shall be permitted to make such disclosure, the Minefinders Board shall not be permitted to make a Minefinders Change in Recommendation, other than as permitted by Subsection 7.1(e) or 7.1(h)(i). Pan American and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such disclosure, recognizing that whether or not such comments are appropriate will be determined by Minefinders, acting reasonably.

(i) Minefinders acknowledges and agrees that each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for the purposes of this Section 7.1.

(j) Minefinders shall ensure that the officers, directors and employees of Minefinders and its Subsidiaries and any investment bankers or other advisors or representatives retained by Minefinders and/or its Subsidiaries in connection with the transactions contemplated by this Agreement are aware of the provisions of this Section, and Minefinders shall be responsible for any breach of this Section 7.1 by such officers, directors, employees, investment bankers, advisors or representatives.

(k) If Minefinders provides Pan American with the notice of an Acquisition Proposal for Minefinders contemplated in this Section 7.1 on a date that is less than seven (7) calendar days prior to the Minefinders Meeting, if requested by Pan American, Minefinders shall adjourn the Minefinders Meeting to a date that is not less than seven (7) calendar days and not more than ten (10) calendar days after the date of such notice; provided, however, that in the event that the Meeting is so adjourned, the Meeting Deadline and the Outside Date shall be extended by the same number of days as the Meeting has been adjourned or postponed.

ARRANGEMENT

3.1	Arrangement

Commencing at the Effective Time, except as otherwise noted herein, the following shall occur and shall be deemed to occur in one minute intervals, in the following order, without any further act or formality required on the part of any person:

(a)

all Minefinders Shares to be issued to Minefinders Optionholders who have tendered Conditional Exercise Notices, together with the applicable exercise price, for any Minefinders Options that are vested at or prior to the Effective Time (including any unvested Minefinders Options whose vesting was accelerated pursuant to section 3.4(f) of the Minefinders 2003 Option Plan or section 6 of the Minefinders 2011 Option Plan), will be deemed to be issued to such Minefinders Optionholders, as fully paid and non-assessable common shares in the capital of Minefinders, such Minefinders Optionholders will be entered in the share register of Minefinders as the registered holder thereof and no share certificates in respect of such Minefinders Shares shall be issued;

(b)

each Dissenting Share held by a Dissenting Shareholder shall be deemed to have been transferred to Pan American, and

(i)

the Dissenting Shareholder shall cease to be the registered holder of such Dissenting Shares and shall cease to have any rights as a Minefinders Shareholder in respect of such Dissenting Shares other than the right to be paid fair value by Pan American for such Dissenting Shares as set out in Article 4 of this Plan of Arrangement;

(ii)

the Dissenting Shareholder’s name shall be removed as the holder of such Dissenting Shares from the register of Minefinders Shareholders; and

A-7

(iii)

Pan American will be the holder of all of the Dissenting Shareholder’s Dissenting Shares and the register of Minefinders Shareholders shall be revised accordingly;

(c)

subject to Sections 3.2, 3.3 and 3.5 of this Plan of Arrangement, each Minefinders Share held by a Minefinders Shareholder (other than Minefinders Shares held by Pan American and its Affiliates and (without duplication) Dissenting Shares but, for greater certainty, including Minefinders Shares acquired by former Minefinders Optionholders pursuant to Subsection 3.1(a) of this Plan of Arrangement) shall be transferred by the holder thereof to Pan American in exchange for (as elected or deemed to be elected by the holder in accordance with the Minefinders Shareholder’s Letter of Transmittal or (in respect of Minefinders Shares issued to former Minefinders Optionholders in accordance with subsection 3.1(a) of this Plan of Arrangement) Conditional Exercise Notice:

(i)

the Cash Option;

(ii)

the Pan American Share Option; or

(iii)

the Full Proration Option,

and (1) the Former Minefinders Shareholder shall cease to be the registered holder of each Minefinders Share so transferred and shall be the holder of the Pan American Shares received by it pursuant to Subsection 3.1(c) of this Plan of Arrangement (if any), and the name of such Former Minefinders Shareholder shall be removed from the register of Minefinders Shareholders and shall be entered into the register of holders of Pan American Shares as the holder of the Pan American Shares received by it pursuant to Subsection 3.1(c) (if any); (2) the Former Minefinders Shareholder shall be deemed to have executed and delivered all consents, releases, assignments and waivers, statutory or otherwise, required to transfer and assign such Minefinders Share hereunder; (3) Pan American will be the holder of all of the outstanding Minefinders Shares and the register of Minefinders Shareholders shall be revised accordingly; and (4) unless the Minefinders Shareholder receives only cash for Minefinders Shares owned by such Minefinders Shareholder, a pro rata portion of the total amount of cash and the total number of Pan American Shares received by such Minefinders Shareholder pursuant to this Subsection 3.1(c) as adjusted by Sections 3.2 and 3.5 of this Plan of Arrangement, if applicable, will be allocated to every Minefinders Share transferred by such Minefinders Shareholder hereunder, so that such Minefinders Shareholder will receive for each such Minefinders Share the same combination of Pan American Shares and cash as it receives for each other Minefinders Share held by it and neither Pan American Shares nor cash will be considered to have been received for any specific portion or fraction of such Minefinders Share;

(d)

each outstanding Minefinders Option in respect of which Pan American Shares are not issued in accordance with Subsection 3.1(a) of this Plan of Arrangement shall be exchanged for an option (each, a “Replacement Option”) to purchase from Pan American the number of Pan American Shares equal to: (i) the Option Exchange Ratio multiplied by (ii) the number of Minefinders Shares subject to such Minefinders Option immediately prior to the Effective Time. Such Replacement Option shall provide for an exercise price per Pan American Share (rounded up to the nearest whole cent) equal to: (x) the exercise price per Minefinders Share otherwise purchasable pursuant to such Minefinders Option; divided by (y) the Option Exchange Ratio. If the foregoing

A-8

calculation results in the total Replacement Options of a particular holder being exercisable for a number of Pan American Shares that includes a fractional Pan American Share, the total number of Pan American Shares subject to such holder’s total Replacement Options shall be rounded down to the nearest whole number of Pan American Shares. All terms and conditions of a Replacement Option, including the term to expiry, conditions to and manner of exercise, will be the same as the Minefinders Option for which it was exchanged, except that the expiry date for all Replacement Options for which Minefinders 2011 Options are exchanged and which are held by employees, officers, directors or consultants of Minefinders or its Affiliates:

(i)

who cease to be employees, officers, directors or consultants of Minefinders of any of its Affiliates on the Effective Date will be extended to the earlier of (a) 12 months from the Effective Date, and (b) the original expiry date (absent such cessation) of any such Minefinders 2011 Option; and

(ii)

whose service with Minefinders, Pan American or any Affiliate thereof is terminated other than for cause after the Effective Date will be extended to the earlier of (a) the later of (1) 12 months from the Effective Date, and (2) 90 days from the date of such termination, and (b) the original expiry date (absent such termination) of any such Minefinders 2011 Option.

Notwithstanding the foregoing, if required, the exercise price of each Replacement Option of any particular holder shall be, and shall be deemed to be, adjusted by the amount, and only to the extent, necessary to ensure that the In the Money Amount of the Replacement Option does not exceed the In the Money Amount of the original Minefinders Option immediately before the exchange;

(e)

each outstanding Minefinders Share (including any Minefinders Share held by Pan American or any Affiliate thereof) shall be transferred without any further act or formality by the holder thereof to Acquireco in exchange for one common share of Acquireco;

(f)

the stated capital in respect of the Minefinders Shares shall be reduced to $1.00 without any repayment of capital in respect thereof;

(g)

Minefinders and Acquireco will merge (the “Amalgamation”) to form one corporate entity with the same effect as if they were amalgamated under sections 174 through 179 (other than section 177) of Part XIV of the OBCA, except that the separate legal existence of Minefinders will not cease and Minefinders will survive the Amalgamation (Minefinders, as such surviving entity, “Amalco”) and, for the avoidance of doubt, the Plan of Arrangement is intended to qualify as a reorganization within the meaning of sections 368(a)(1)(A) and 368(a)(2)(E) of the Code for all United States federal income tax purposes and as an amalgamation as defined in subsection 87(1) of the Tax Act;

(h)

without limiting the generality of the foregoing or Subsection 3.1(i) of this Plan of Arrangement,

(i)

at the time of the Amalgamation the separate legal existence of Acquireco will cease without Acquireco being liquidated or wound-up, and Minefinders and Acquireco will continue as one company; and

A-9

(ii)

the Amalgamation will otherwise be effected in such manner that by virtue or because of the Amalgamation (A) all of the property of Acquireco or Minefinders immediately before the Amalgamation (except amounts receivable from either of them, and shares in the capital stock of either of them) will be or become property of Amalco, (B) all of the liabilities of Acquireco or Minefinders immediately before the Amalgamation (except amounts payable to either of them) will be or become liabilities of Amalco, (C) each issued share of Acquireco will be exchanged for one fully-paid and non-assessable Amalco common share which shall be issued by Amalco and all such Acquireco shares will be cancelled without any payment of capital in respect thereof, and (D) all of the Minefinders Shares held by Acquireco will be cancelled without any payment of capital in respect thereof;

(i)

with effect from the time of the Amalgamation but subject to Subsection 3.1(h):

(A)

Amalco will continue to own and hold all property of Minefinders and will own and hold all property of Acquireco, and shall continue to be liable for the obligations of Minefinders and will be liable for the obligations of Acquireco, including civil, criminal and quasi-criminal liabilities and all contracts, disabilities, options and debts of each of Minefinders and Acquireco;

(B)

all rights, contracts, permits and interests of Minefinders or Acquireco will continue as rights, contracts, permits and interests of Amalco and, for greater certainty, the merger will not constitute a transfer or assignment of the rights or obligations of either of Minefinders or Acquireco under any such rights, contracts, permits and interests;

(C)

any existing cause of action, claim or liability to prosecution is unaffected;

(D)

a civil, criminal or administrative action or proceeding pending by or against Minefinders or Acquireco may continue to be prosecuted by or against Amalco;

(E)

a conviction against, or ruling, order or judgment in favour of or against, Minefinders or Acquireco may be enforced by or against Amalco;

(F)

the name of Amalco shall be Minefinders;

(G)

Amalco shall be authorized to issue an unlimited number of common shares;

(H)

the articles and by-laws of Amalco shall be substantially in the form of Minefinders’ articles and by-laws;

(I)

the first annual general meeting of Amalco will be held within 18 months from the Effective Date;

(J)

the first directors of Amalco following the merger shall be ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇, A. ▇▇▇▇▇▇ ▇▇▇▇▇ and ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇; and

A-10

(K)

the stated capital of the Amalco common shares will be an amount equal to the paid-up capital, as that term is defined in the Tax Act, attributable to the common shares of Acquireco immediately prior to the Amalgamation,

provided that none of the foregoing will occur or be deemed to occur unless all of the foregoing occurs or is deemed to occur.

3.2 Adjustments to Cash and Share Elections

For the purposes of determining the amount of cash and/or Pan American Shares which each Minefinders Shareholder is entitled to receive for each Minefinders Share transferred pursuant to Subsection 3.1(c), the following proration rules shall apply:

(a)

if the Elected Cash Amount exceeds the Available Cash Amount, then, notwithstanding the election of the Cash Option by a Minefinders Shareholder in respect of any particular Minefinders Share, each Minefinders Shareholder (other than Pan American and its Affiliates and Dissenting Shareholders) who has elected the Cash Option in respect of any Minefinders Shares:

(i)

will receive cash equal in amount to the amount that such Minefinders Shareholder would have received if such Minefinders Shareholder had elected the Cash Option in respect of the number of Minefinders Shares that is equal to the product of (1) the total number of Minefinders Shares in respect of which the Minefinders Shareholder elected the Cash Option, and (2) the number obtained by dividing (i) (a) the Available Cash Amount less (b) $1.84 multiplied by the aggregate number of Minefinders Shares in respect of which all Minefinders Shareholders have elected or are deemed to have elected the Full Proration Option, by (ii) (a) the Elected Cash Amount less (b) $1.84 multiplied by the aggregate number of Minefinders Shares in respect of which all Minefinders Shareholders have elected or are deemed to have elected the Full Proration Option, and rounding such resulting number up to the nearest whole number, and

(ii)

(b)

if the Elected Share Amount exceeds the Available Share Amount, then, notwithstanding the election of the Pan American Share Option by a Minefinders Shareholder in respect of any particular Minefinders Share, each Minefinders Shareholder (other than Pan American and its Affiliates and Dissenting Shareholders) who has elected the Pan American Share Option in respect of any Minefinders Shares:

(i)

will receive Pan American Shares and cash equal in amount to the amount that such Minefinders Shareholder would have received if such Minefinders Shareholder had elected the Pan American Share Option in respect of the number of Minefinders Shares that is equal to the product of (1) the total number of Minefinders Shares in respect of which the Minefinders Shareholder elected the Pan American Share Option, by (2) the number obtained by dividing

A-11

(i) (a) the Available Share Amount less (b) 0.55 multiplied by the aggregate number of Minefinders Shares in respect of which all Minefinders Shareholders have elected or are deemed to have elected the Full Proration Option, by (ii) (a) the Elected Share Amount less (b) 0.55 multiplied by the aggregate number of Minefinders Shares in respect of which all Minefinders Shareholders have elected or are deemed to have elected the Full Proration Option, and rounding such resulting number up to the nearest whole number, and

(ii)

will receive cash equal in amount to the amount that such Minefinders Shareholder would have received if such Minefinders Shareholder had elected the Cash Option for the remainder of the Minefinders Shares in respect of which it elected the Pan American Share Option.

3.3 Manner of Making Elections

(a)

Subject to Sections 3.2 and 3.5 hereof, each Minefinders Shareholder shall, in respect of such holder’s aggregate holdings of Minefinders Shares, have the opportunity to elect the Cash Option, the Pan American Share Option, the Full Proration Option or a combination thereof by depositing, or by causing its agent or other representative to deposit, with the Depositary prior to the Election Deadline, a duly completed Letter of Transmittal (or in the case of a former Minefinders Optionholder to whom Minefinders Shares are issued in accordance with Subsection 3.1(a) of this Plan of Arrangement, a Conditional Exercise Notice) indicating such holder’s election together with the certificates representing such holder’s Minefinders Shares.

(b)

Subject to Sections 3.2 and 3.5 hereof, of each Minefinders Shareholder who (i) does not deposit with the Depositary a duly completed Letter of Transmittal (or in the case of a former Minefinders Optionholder to whom Minefinders Shares are issued in accordance with Subsection 3.1(a) of this Plan of Arrangement, a Conditional Exercise Notice) prior to the Election Deadline or (ii) otherwise fails to comply fully with the requirements of Subsection 3.3(a) hereof and the Letter of Transmittal (or in the case of a former Minefinders Optionholder to whom Minefinders Shares are issued in accordance with Subsection 3.1(a) of this Plan of Arrangement, a Conditional Exercise Notice) in respect of such Minefinders Shareholder’s election of the Cash Option, the Pan American Share Option or the Full Proration Option, shall be deemed to have elected the Full Proration Option in respect of each of the Minefinders Shareholder’s Minefinders Shares.

(c)

A deposit of a Letter of Transmittal or Conditional Exercise Notice and accompanying certificates may be made at any of the offices of the Depositary specified in the Letter of Transmittal or Conditional Exercise Notice, as the case may be.

3.4	Post-Effective Time Procedures

(a)

For greater certainty, no Minefinders Optionholder to whom Minefinders Shares are issuable pursuant to Subsection 3.1(a) of this Plan of Arrangement shall be required to deliver share certificates representing the Minefinders Shares issued to such former Minefinders Optionholder pursuant to Subsection 3.1(a) of this Plan of Arrangement in order to receive the Consideration to which it is entitled for such Minefinders Shares in accordance with Subsection 3.1(c) of this Plan of Arrangement and no other Minefinders Optionholder who exercises Minefinders Options prior to or at the Effective Time shall be required to deliver share certificates representing Minefinders Shares to the extent that

A-12

such certificates were not issued prior to the Election Deadline and provided such other Minefinders Optionholder otherwise provides satisfactory documentation evidencing due exercise of each Minefinders Option.

(b)

Following the receipt of the Final Order and prior to the Effective Date, Pan American shall deliver or arrange to be delivered to the Depositary sufficient cash and certificates representing the Pan American Shares required to be issued to Former Minefinders Shareholders in accordance with the provisions of Subsection 3.1(c) hereof, to be held by the Depositary as agent and nominee for such Former Minefinders Shareholders for distribution to such Former Minefinders Shareholders in accordance with the provisions of Article 5 hereof.

(c)

An Eligible Holder whose Minefinders Shares are exchanged for Consideration that includes Pan American Shares pursuant to the Arrangement shall be entitled to make an income tax election, pursuant to section 85 of the Tax Act (and any analogous provision of provincial income tax law) (a “Section 85 Election”) with respect to the exchange by providing the necessary information and two properly completed copies of the election form prescribed by the Tax Act (and, if applicable, any provincial tax statute) (collectively, a “Section 85 Tax Election Form”) in accordance with the procedures set out in the tax instruction letter on or before 90 days after the Effective Date (the “Section 85 Election Period”). Provided such information is correct and complete and in compliance with requirements imposed under the Tax Act (or applicable provincial income tax law), Pan American shall, within 90 days after the end of the Section 85 Election Period, deliver two signed copies of each Section 85 Tax Election Form so delivered to it to such Eligible Holders for filing with the applicable Government Entities. Notwithstanding the previous sentence, but provided that Pan American signs and returns each properly completed Section 85 Tax Election Form received by it before the end of the Section 85 Election Period to the applicable Eligible Holders, neither Minefinders, Pan American nor any successor corporation shall be responsible for ensuring the proper completion of any Section 85 Tax Election Form nor, for any taxes, interest or penalties resulting from the failure of an Eligible Holder to complete or file such election forms properly in the form and manner and within the time prescribed by the Tax Act (or any applicable provincial legislation). In its sole discretion, Pan American or any successor corporation may choose to execute and deliver a Section 85 Tax Election Form to an Eligible Holder that does not provide the necessary information within the Section 85 Election Period, but will have no obligation to do so.

(d)

Pan American will deliver a tax instruction letter to an Eligible Holder promptly upon receipt of a Letter of Transmittal in which the Eligible Holder has indicated that such holder wishes to receive a tax instruction letter. The tax instruction letter will provide general instructions on how to make a Section 85 Election with Pan American in respect of the sale of the Eligible Holder’s Minefinders Shares to Pan American.

3.5	No Fractional Pan American Shares and Rounding of Cash Consideration

(a)

In no event shall a Minefinders Shareholder be entitled to a fractional Pan American Share. Where the aggregate number of Pan American Shares to be issued to a Minefinders Shareholder as consideration under this Arrangement would result in a fraction of a Pan American Share being issuable, the number of Pan American Shares to be received by such Minefinders Shareholder shall be rounded down to the nearest whole Pan American Share and in lieu of a fractional Pan American Share, the Minefinders

A-13

Shareholder will receive a cash payment in Canadian dollars (rounded down to the nearest cent) determined on the basis of an amount equal to (i) the Pan American Share Closing Price, multiplied by the (ii) fractional share amount.

(b)

If the aggregate amount of cash consideration which a Minefinders Shareholder is entitled to receive for all Minefinders Shares transferred by such Minefinders Shareholder pursuant to the Plan would otherwise include a fraction of $0.01, then the aggregate cash consideration to which such Minefinders Shareholder shall be entitled to receive for all of its Minefinders Shares transferred pursuant to the Plan shall be rounded up to the nearest whole $0.01.

ARTICLE 4

DISSENT RIGHTS

4.1	Rights of Dissent

(a)

Pursuant to the Interim Order, registered Minefinders Shareholders may exercise rights of dissent (“Dissent Rights”) under section 185 of the OBCA, as modified by this Article 4, the Interim Order and the Final Order, with respect to Minefinders Shares in connection with the Arrangement; provided, however, that the written notice setting forth the objection of such registered Minefinders Shareholders to the Arrangement and exercise of Dissent Rights must be received by Minefinders not later than 5:00 p.m. on the Business Day that is two (2) Business Days before the Minefinders Meeting or any date to which the Minefinders Meeting may be postponed or adjourned; and provided further that Dissenting Shareholders who:

(i)

are ultimately entitled to be paid fair value for their Minefinders Shares by Pan American, which fair value, notwithstanding anything to the contrary contained in the OBCA, shall be determined as of the close of business on the day before the Effective Date, shall be deemed to have transferred their Minefinders Shares to Pan American in accordance with Subsection 3.1(b); or

(ii)

are ultimately not entitled, for any reason, to be paid fair value for their Minefinders Shares shall be deemed to have participated in the Arrangement, as of the Effective Time, on the same basis as a non-dissenting holder of Minefinders Shares and shall be entitled to receive only the Consideration that such holder would have received pursuant to the Arrangement if such holder had not exercised Dissent Rights on the basis determined in accordance with Subsections 3.1(c) and 3.3(b) above (subject to Section 3.5).

(b)

In no circumstances shall Minefinders, Pan American or any other Person be required to recognize a Person as a Dissenting Shareholder unless such Person is a registered holder of those Minefinders Shares in respect of which such rights are sought to be exercised.

(c)

For greater certainty, in no case shall Minefinders, Pan American or any other Person be required to recognize Dissenting Shareholders as holders of Minefinders Shares after the Effective Time, and the names of all Dissenting Shareholders shall be deleted from the register of Minefinders Shareholders as of the Effective Time. In addition to any other restrictions under section 185 of the OBCA and, for greater certainty, none of the following shall be entitled to exercise Dissent Rights: (i) holders of Minefinders Options; and (ii) Minefinders Shareholders who vote, or who have instructed a proxyholder to vote, in favour of the Arrangement Resolution.

A-14

ARTICLE 5

DELIVERY OF PAN AMERICAN SHARES

5.1	Delivery of Pan American Shares

(a)

Subject to Section 5.5 of this Plan of Arrangement, as soon as practicable following the later of the Effective Time and the date of surrender to the Depositary for cancellation of a certificate (if any) that immediately before the Effective Time represented one or more outstanding Minefinders Shares that were exchanged for Pan American Shares in accordance with Subsection 3.1(c) hereof, together with such other documents and instruments contemplated by the Letter of Transmittal and such additional documents and instruments as the Depositary may reasonably require, the Former Minefinders Shareholder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall, and Pan American shall cause the Depositary to:

(i)

forward or cause to be forwarded by first class mail (postage prepaid) to the Former Minefinders Shareholder at the address specified in the Letter of Transmittal; or

(ii)

if requested by the holder in the Letter of Transmittal, make available at the offices of the Depositary specified in the Letter of Transmittal for pick-up by the Former Minefinders Shareholder; or

(iii)

a certificate representing the Pan American Shares that such Former Minefinders Shareholder is entitled to receive, together with a cheque payable to such Minefinders Shareholders for the cash consideration payable to such Former Minefinders Shareholders, in accordance with Subsection 3.1(c) of this Plan of Arrangement.

(b)

After the Effective Time and until surrendered for cancellation as contemplated by Subsection 5.1(a) hereof, each certificate that immediately prior to the Effective Time represented one or more Minefinders Shares shall be deemed at all times to represent only the right to receive in exchange therefor the Consideration that the holder of such certificate is entitled to receive in accordance with Subsection 3.1(c) hereof.

(c)

As soon as practicable following the Effective Date but in any event within five (5) Business Days after the Effective Date, each former Minefinders Optionholder to whom Minefinders Shares are deemed to have been issued in accordance with Subsection 3.1(a) of this Plan of Arrangement, shall be entitled to receive, and the Depositary shall, and Pan American shall cause the Depositary to:

(i)

forward or cause to be forwarded by first class mail (postage prepaid) to the holder at the address specified in the Conditional Exercise Notice; or

A-15

(ii)

if requested by the holder in the Conditional Exercise Notice, make available at the offices of the Depositary specified in the Conditional Exercise Notice for pick-up by the holder; or

(iii)

if the Conditional Exercise Notice neither specifies an address as described in (i) above nor contains a request as described in (ii) above, forward or cause to be forwarded by mail (postage prepaid) to the holder at the address of such holder as shown on the register of Minefinders Options maintained by or on behalf of Minefinders as at the Effective Time,

a certificate representing the Pan American Shares that such former Minefinders Optionholder is entitled to receive, together with a cheque payable to such Minefinders Optionholder for the cash consideration payable to such former Minefinders Optionholder, in accordance with Subsection 3.1(c) of this Plan of Arrangement.

5.2	Lost Certificates

If any certificate, that immediately prior to the Effective Time represented one or more outstanding Minefinders Shares that were exchanged for the Consideration in accordance with Section 3.1 hereof, shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder claiming such certificate to be lost, stolen or destroyed, the Depositary shall deliver in exchange for such lost, stolen or destroyed certificate, the Consideration that such holder is entitled to receive in accordance with Section 3.1 hereof. When authorizing such delivery of Consideration that such holder is entitled to receive in exchange for such lost, stolen or destroyed certificate, the holder to whom such Consideration is to be delivered shall, as a condition precedent to the delivery of such Consideration, give a bond satisfactory to Pan American and the Depositary in such amount as Pan American and the Depositary may direct, or otherwise indemnify Pan American and the Depositary in a manner satisfactory to Pan American and the Depositary, against any claim that may be made against Pan American or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed and shall otherwise take such actions as may be required by the articles and by-laws of Minefinders.

5.3	Distributions with Respect to Unsurrendered Certificates

No dividend or other distribution declared or made after the Effective Time with respect to Pan American Shares with a record date after the Effective Time shall be delivered to the holder of any unsurrendered certificate that, immediately prior to the Effective Time, represented outstanding Minefinders Shares unless and until the holder of such certificate shall have complied with the provisions of Section 5.1 or Section 5.2 hereof. Subject to applicable Law and to Section 5.4 hereof, at the time of such compliance, there shall, in addition to the delivery of Consideration to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of all dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such Pan American Shares.

5.4	Withholding Rights

Pan American, Minefinders and the Depositary shall be entitled to deduct and withhold from all dividends, distributions or other amounts otherwise payable to any Former Minefinders Shareholder such amounts as Pan American, Minefinders or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the Code or any provision of any applicable federal, provincial, state, local or foreign tax Law or treaty, in

A-16

each case, as amended (a “Withholding Obligation”). To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the Former Minefinders Shareholder in respect of which such deduction and withholding was made, provided, however, that such withheld amounts are actually remitted to the appropriate taxing authority. Pan American, Minefinders and the Depositary shall also have the right to withhold and sell, on their own account or through a broker (the “Broker”), and on behalf of any Former Minefinders Shareholder, such number of Pan American Shares issued or issuable to such Former Minefinders Shareholder pursuant to this Plan of Arrangement as is necessary to produce sale proceeds (after deducting commissions payable to the Broker and other costs and expenses) sufficient to fund any Withholding Obligations. Any such sale of Pan American Shares shall be affected on a public market and as soon as practicable following the Effective Date. None of Pan American, Minefinders, the Depositary or the Broker will be liable for any loss arising out of any sale of such Pan American Shares, including any loss relating to the manner or timing of such sales, the prices at which the Pan American Shares are sold or otherwise.

5.5	Limitation and Proscription

To the extent that a Former Minefinders Shareholder shall not have complied with the provisions of Section 5.1 or Section 5.2 hereof on or before the date that is six (6) years after the Effective Date (the “Final Proscription Date”), then the Consideration that such Former Minefinders Shareholder was entitled to receive shall be automatically cancelled without any repayment of capital in respect thereof and the Consideration to which such Former Minefinders Shareholder was entitled, shall be delivered to Pan American by the Depositary and certificates representing Pan American Shares forming the Consideration shall be cancelled by Pan American, and the interest of the Former Minefinders Shareholder in such Pan American Shares to which it was entitled shall be terminated as of such Final Proscription Date.

5.6	No Encumbrances
