The Buyer hereby agrees to indemnify the Seller against and agrees to hold the Seller harmless from any and all damages, claims, losses, liabilities, fines, penalties and expenses (including reasonable legal fees) (a “Claim”) incurred or suffered by any of them arising out of any misrepresentation or breach of warranty, covenant or agreement made or to be performed by the Buyer pursuant to this Agreement or any Transaction Document.

The Seller hereby agrees to indemnify the Buyer and its directors, officers, employees and agents against and agree to hold them harmless from any and all Claims incurred or suffered by any of them arising out of: (i) any misrepresentation or breach of warranty, covenant or agreement made or to be performed by the Seller under this Agreement; or (ii) any failure of the Seller to file the requisite tax return with respect to the completion of the Transaction and the payment of applicable tax pursuant to the (Mexican) Income Tax Law (Ley del Impuesto Sobre la Renta).

- 37 -

9.3 Claims of Indemnity. Any indemnified Party under this Article 9 shall give prompt notice to the indemnifying Party or Parties of any claim, action, proceeding or circumstances that could reasonably give rise to such a Claim. Inadvertent failure to give such prompt notice will not preclude the indemnified Party from pursuing the claim unless and to the extent that the indemnifying Party is materially prejudiced by such failure. The indemnifying Party shall have the right, upon written notice to the indemnified Party, at its own expense and in the name of the indemnified Party or otherwise, to defend and dispute any Claim made, or any matter on which a Claim could be made, by a third party in respect of which a notice has been given by the indemnified Party under this section and may retain legal counsel to have conduct of any proceeding relating to such a Claim. The indemnified Party may employ separate counsel with respect to any such Claims brought by a third party and participate in the defence thereof, provided that the fees and expenses of such counsel shall be the responsibility of the indemnified Party unless the indemnifying Party fails to assume the defence of such Claim on behalf of the indemnified Party within ten days of receiving notice of such claim or the employment of such counsel at the indemnifying Party’s expense has been authorized by the indemnifying Party, in either of which cases the indemnifying Party shall not have the right to assume the defence of such suit on behalf of the indemnified Party but shall be liable to pay the reasonable fees and expenses of counsel for the indemnified Party. For the purpose of confirming or disputing such a claim, the indemnified Party shall provide full and complete disclosure to the indemnifying Party and complete access to and right of inspection by the representatives of the indemnifying Party of all documents and records in the possession or control of the indemnified Party relating to such Claim. If requested by the indemnifying Party, the indemnified Party shall provide reasonable assistance to the indemnifying Party in disputing or defending such Claim, provided that any material amount of assistance shall be at the expense of the indemnifying Party. If any security is required to be provided for the purpose of defending or contesting any such Claim, including without limitation, any appeal of any judgment, the indemnifying Party shall provide such security and all monies or property representing such security received by the indemnified Party as a result of a successful defence or contestation shall be held in trust by the indemnified Party for the benefit of the indemnifying Party and shall be remitted to the indemnifying Party on demand. Neither the indemnified Party nor the indemnifying Party shall settle, compromise or pay any Claim for which indemnity is sought hereunder except with the prior written consent of the other, such consent not to be unreasonably withheld, unless otherwise ordered to do so by a court of competent jurisdiction.

9.4 Agency for Representatives. Each of the Buyer and the Seller agrees that it accepts each indemnity in favour of any of its respective directors, officers, employees or agents, as the case may be, as agent and trustee of that director, officer, employee or agent. Each Party agrees that the Buyer and the Seller may enforce an indemnity in favour of any of that Party’s directors, officers, employees or agents.

- 38 -

9.5 Limitations. Notwithstanding anything else in this Agreement:

(a) the amount which an indemnifying Party is required to pay in respect of a Claim pursuant to this Article shall be reduced by any foreign or local Tax benefit to the indemnified Party applicable to the amount of the Claim (calculated on a net present value basis by the indemnified Party, acting reasonably) and by the amount of any insurance proceeds available to the indemnified Party in respect of the Claim; and

(b) in no event will any Party be liable for any indirect, consequential, special or incidental damages, including without limitation, damages resulting from loss of profits.

9.6 Survival of Representations and Warranties. The representations and warranties of each of the Parties set forth herein or in any Transaction Document shall survive for a period of two years from the Closing Date provided that (a) representations and warranties in respect of warranties in respect of Tax matters shall survive so long as assessments or reassessments can be made by the applicable Taxing authorities in respect thereof, and (b) the representations and warranties made by the Buyer pursuant to Section 2.3(c), if applicable, shall survive for a period of two years following the Buyer’s delivery of the certificate as contemplated in such section. However, the indemnity contained in section 9.2(ii) shall not be subject to any time limit and shall be for an indefinite period of time.

9.7 Exclusive Rights. The rights of indemnity set forth in this Article are intended to be and will be the sole and exclusive right and remedy of the Parties in respect of any Claim under this Agreement, any Transaction Document and the Transaction contemplated hereby and thereby.

9.8 Set Off. The Buyer shall have the right to set off first as against any or all of the Second Cash Payment, the Advance MII Payment, the MII Payment, the New MII Ounces Payment and the Third Cash Payment, any amounts that may be owing by the Seller further to indemnification Claims the Buyer that have against the Seller pursuant to section 9.2, all until the amount of any such Claim has been completely set off. The foregoing shall not constitute a waiver by the Buyer of any of its rights and remedies under this Agreement. Under no circumstances shall the aforesaid payments be the sole source against which the Buyer may seek indemnification for Claims and the Buyer’s right to indemnification shall not be deemed a limitation on the indemnification obligation of the Seller pursuant to section 9.2. If the Buyer chooses to offset any indemnification Claim against amounts otherwise due hereunder, and the Seller disputes and ultimately prevails in such dispute of the applicable Claim, the Seller shall be entitled, in addition to the prompt payment of the offset amount, from the Buyer (unless the Seller has already recovered any such amounts from a third Party). The Buyer shall also pay the Seller’s reasonable legal fees and expenses incurred in the dispute of such claim.

Details of Tax Litigation

Chihuahua, Chih. A 31 de Enero de 2012

Re: Embargo de concesiones mineras propiedad

de American Copper Mining S.A de C.V.

Xxxxxx X. Xxxxxxxx

President, Adit Resources Corp

Por medio de la presente nos permitimos hacerle llegar una breve exposición de los antecedentes, situación actual, y solución propuesta en relación a siete concesiones mineras propiedad de American Copper Mining S.A de C.V., (ACM) y el embargo impuesto por la Secretaria de Hacienda y Crédito Publico sobre dichas concesiones mineras.

1.- Xx 00 xx Xxxxx 0000, XXX adquiere mediante Contrato de Cesión Onerosa celebrado con el Sr. Xxxxxx Xxxxx la titularidad de ocho concesiones mineras que a continuación se describen:

Nombre de Concesión	Titulo.	Hectáreas

El Picacho	161838	21
Mis Recuerdos	214776	2.1708
Picacho II	218818	448.5564
Dos Amigos	222511	24.43
Picacho II	222789	4.9217
El Picacho I	222925	2155.6890
Creston	226154	84.

2.- El 14 xx Xxxx de 2010 se inscriben a favor de ACM en el Registro de Minería siete de las concesiones adquiridas a Xxxxxx Xxxxx descritas en el párrafo que antecede.

A partir de esta fecha, es público que el titular de las referidas concesiones lo viene a ser ACM.

3.- El 21 de Abril de 2011, se determino un crédito fiscal a cargo de diversa empresa minera denominada Corporación Amermin S.A. de C.V. (Amermin) razón por la cual la Secretaria de Hacienda y Crédito Publico (SHCP) por conducto de la Administración Local Jurídica de Chihuahua ordeno el requerimiento de pago y embargo en contra de Corporación Amermin.

Esta empresa, Amermin, es desde luego diversa entidad separada e independiente en todo sentido de ACM.

4.- El 00 xx Xxxx xx 0000, xx XXXX xxxxx a cabo el requerimiento de pago del crédito fiscal a Amermin y en razón de que en el momento de llevar a cabo el requerimiento no se realizo el pago, se procedió a embargar bienes para garantizar la cantidad adeudada xx xxxxx federal por parte de Amermin.

Para ello, la SHCP embargo diversas concesiones mineras propiedad de Amermin así como otras distintas concesiones mineras que al momento del embargo ya no eran propiedad de Amermin.

Específicamente, dicha autoridad, incorrectamente efectuó, adicionalmente el embargo sobre las siguientes concesiones propiedad de ACM:

Nombre de Concesión	Titulo.	Hectáreas

El Picacho	161838	21
Mis Recuerdos	214776	2.1708
Picacho II	218818	448.5564
Dos Amigos	222511	24.43
Picacho II	222789	4.9217
El Picacho I	222925	2155.6890
Creston	226154	84.

5.- Xx 00 xx Xxxxx xx 0000, Xxxxxxx, xxxxxx en contra de la SHCP un Juicio de Nulidad en el cual impugna y combate la determinación y procedencia del crédito fiscal determinado en su contra así como el embargo practicado en dicho procedimiento.

Este juicio se encuentra en curso actualmente y se lleva bajo el expediente Xx. 0000/00-00-00-0 xx xx Xxxx Xxxxxxxx Xxxxx Xxxxxx I del Tribunal Federal de Justicia Fiscal y Administrativa con sede en esta Ciudad de Chihuahua Chihuahua.

6.- El 22 de Xxxxx de 2011, se inscriben en el Registro de Minería, en cada una de las concesiones mineras de ACM, la existencia del embargo llevado a cabo por la SHCP, y desde esa fecha hasta el presente aparece la anotación de que dichas concesiones tienen el gravamen derivado del embargo antes descrito.

Evidentemente, este embargo carece de fundamento y por lo tanto es ilegal ya que ACM es ajeno a los créditos fiscales que tenga Amermin.

7.- A pesar de la evidente ilegalidad en el embargo, la SHCP no retira el embargo hasta no tener alguna de las siguientes situaciones.

a. Que xx xxxxx el crédito fiscal. Ello implica la aceptación y pago total del mismo por el contribuyente Amermin.

b. Que el Juicio de Nulidad que actualmente está en curso se finalice de manera favorable para Amermin. Por la carga de trabajo de los tribunales, esta resolución puede tardara hasta dos años en resolverse.

- 2 -

c. Que un Juez se lo ordene expresamente. Para ello se requiere iniciar un juicio en contra de la SHCP el cual, a pesar de acreditarse fácilmente el grave error del embargo, se lleva un por lo menos cuatro meses de duración.

d. Que se le sustituyan los bienes embargados por otra garantía. Esto se puede lograr mediante la obtención de una Fianza por parte de una Compañía Afianzadora.

8.- Ante este escenario y la necesidad de lograr la liberación del embargo lo antes posible, la recomendación que se le realiza a las empresas involucradas, ACM y Amermin, es que se utilice como primera opción la descrita en el inciso d referida en el párrafo que antecede, es decir, la sustitución de la garantía.

Esta opción es probablemente la más xxxxxx y más rápida de obtener, ya que al reunir todos los requisitos que pide la Compañía Afianzadora se expediría la fianza solicitada.

9.- Los pasos y tiempos aproximados para lograr la liberación del embargo bajo la opción de la obtención de la fianza serian los siguientes:

Expedir la Fianza, previo la entrega de los documentos requeridos y hacer el deposito solicitados por la Compañía Afianzadora…………. 2 Semanas.

Autorización de la aceptación de la fianza y la expedición de la orden al Registro de Minería de la cancelación de los embargos por parte de la SHCP………………………………………………………….……….5 Semanas.

Recepción y registro del oficio de cancelación ante el registro así como eliminación de la anotación de embargo sobre cada una de las concesiones embragadas por parte del registro de Minería….…8 Semanas.

Estos tiempos son estimados, ellos dependen de la carga de trabajo de cada dependencia y evidentemente en cada instancia se realizara el mejor esfuerzo para gestionar la rápida tramitación de cada fase del proceso.

Sin más por el momento, y esperando que la presente describa la situación actual que guardan las concesiones embargadas de ACM, quedamos a sus órdenes para comentar más ampliamente la presente.

Atentamente

Lic. Xxxxxxx Xxxxxxx Xxxx.

Dear Sirs:

RE: Tax Litigation

For good and valuable consideration, the receipt and sufficiency whereof being acknowledged, the undersigned Corporacion Amermin S.A. de C.V. (“Amermin”) does hereby acknowledge and agree as follows:

1. It is subject to tax claims as more particularly described in the tax litigation attached hereto as Schedule “A”.

2. As a result of the tax claims (the “Tax Claims”), certain properties (the “Encumbered Properties”) registered in the name of American Copper Mining S.A. de C.V. (“American Copper”) as set forth in Schedule “B” are subject to embargos to and in favour of the Government of Mexico (the “Government”) as set forth in Schedule “C” attached hereto (the “Embargos”).

3. Yamana Mexico Holdings B.V. (“Yamana Mexico”) has entered into an agreement of purchase and sale dated as of March 23, 2012 (the “Purchase Agreement”) pursuant to which Yamana Mexico has agreed to purchase from Adit Resources Corp. (“ADIT”) and others, all of the issued and shares of American Copper.

4. Closing documents pursuant to the completion of the transactions contemplated in the Purchase Agreement have been deposited in escrow (the “Escrow Deposit”) pending the release of the Embargos from the Encumbered Properties.

5. Yamana, Amermin and ADIT have signed an acknowledgement dated as of even date as to the amount of money (together with interest thereon, containing a buffer of approximately an additional month of interest and inflation updating) that is due and owing to the Government pursuant to the Tax Claims (the “Released Cash”).

6. The Released Cash does not form a part of the Escrow Deposit.

7. Amermin has agreed to grant an irrevocable power of attorney to Xxxxxxx Xxxxxxx Xxxxxxx Xxxxxxxx Xxxxxxx, Xxxx Xxxxxxx Xxxx Xxxxxxxx xx Xxxxxxx and Xxxxx Xxxxxxx Xxxxx, jointly and severally, each of Xxxxxxx-Xxxxxxxx Velasco y Ribe (“RSM”) in the form of Schedule “D” attached hereto (the “Embargo Power of Attorney”), it being understood and agreed that the grant by Amermin of the Embargo Power of Attorney does not detract from Amermin’s obligations to obtain the release of the Embargos from the Encumbered Properties and in such regard, the Embargo Power of Attorney is only granted for ease of administration.

8. The Embargo Power of Attorney is being executed and delivered by Amermin contemporaneous with the execution and delivery of this Amermin Side Letter.

9. For greater certainty and without limitation:

(a) RSM shall accept the Released Cash on Amermin’s behalf;

(b) RSM may shall pay the Released Cash to the Government on Amermin’s behalf;

(c) Amermin shall do all such acts and things and shall not omit to do any acts or things which shall be required to enable RSM to be in a position to make the payment of the Released Cash to the Government, including without limitation, the provision of any and all information from time to time which RSM shall reasonably require in order that the payment is properly applied to the Tax Claim;

(d) If judged necessary by RSM, RSM shall deal with the Government on Amermin’s behalf, on an administrative basis with a view to obtaining the release of the Embargos from the Encumbered Properties;

(e) Amermin shall advise ADIT and Yamana Mexico as and when the Embargos are released from the Encumbered Properties and provide documentary evidence thereof to RSM; and

(f) RSM shall advise Amermin, ADIT and Yamana Mexico as and when additional acts and/or documents are required in order to obtain the release of the Embargos from the Encumbered Properties.

9.

The Released Cash together with interest thereon as aforesaid shall be paid in cash by wire transfer to Yamana Mexico to an account specified by Yamana Mexico, all without set-off, deduction or defalcation.

TAX LITIGATION

Chihuahua, Chih. A 31 de Enero de 2012

Re: Embargo de concesiones mineras propiedad

de American Copper Mining S.A de C.V.

Xxxxxx X. Xxxxxxxx

President, Adit Resources Corp

1.- Xx 00 xx Xxxxx 0000, XXX adquiere mediante Contrato de Cesión Onerosa celebrado con el Sr. Xxxxxx Xxxxx la titularidad de ocho concesiones mineras que a continuación se describen:

Nombre de Concesión	Titulo.	Hectáreas

El Picacho	161838	21
Mis Recuerdos	214776	2.1708
Picacho II	218818	448.5564
Dos Amigos	222511	24.43
Picacho II	222789	4.9217
El Picacho I	222925	2155.6890
Creston	226154	84.

2.- El 14 xx Xxxx de 2010 se inscriben a favor de ACM en el Registro de Minería siete de las concesiones adquiridas a Xxxxxx Xxxxx descritas en el párrafo que antecede.

A partir de esta fecha, es público que el titular de las referidas concesiones lo viene a ser ACM.

Esta empresa, Amermin, es desde luego diversa entidad separada e independiente en todo sentido de ACM.

Para ello, la SHCP embargo diversas concesiones mineras propiedad de Amermin así como otras distintas concesiones mineras que al momento del embargo ya no eran propiedad de Amermin.

Específicamente, dicha autoridad, incorrectamente efectuó, adicionalmente el embargo sobre las siguientes concesiones propiedad de ACM:

Nombre de Concesión	Titulo.	Hectáreas

El Picacho	161838	21
Mis Recuerdos	214776	2.1708
Picacho II	218818	448.5564
Dos Amigos	222511	24.43
Picacho II	222789	4.9217
El Picacho I	222925	2155.6890
Creston	226154	84.

Evidentemente, este embargo carece de fundamento y por lo tanto es ilegal ya que ACM es ajeno a los créditos fiscales que tenga Amermin.

7.- A pesar de la evidente ilegalidad en el embargo, la SHCP no retira el embargo hasta no tener alguna de las siguientes situaciones.

a. Que xx xxxxx el crédito fiscal. Ello implica la aceptación y pago total del mismo por el contribuyente Amermin.

- 2 -

d. Que se le sustituyan los bienes embargados por otra garantía. Esto se puede lograr mediante la obtención de una Fianza por parte de una Compañía Afianzadora.

Esta opción es probablemente la más xxxxxx y más rápida de obtener, ya que al reunir todos los requisitos que pide la Compañía Afianzadora se expediría la fianza solicitada.

9.- Los pasos y tiempos aproximados para lograr la liberación del embargo bajo la opción de la obtención de la fianza serian los siguientes:

Expedir la Fianza, previo la entrega de los documentos requeridos y hacer el deposito solicitados por la Compañía Afianzadora…………. 2 Semanas.

Sin más por el momento, y esperando que la presente describa la situación actual que guardan las concesiones embargadas de ACM, quedamos a sus órdenes para comentar más ampliamente la presente.

Atentamente

Lic. Xxxxxxx Xxxxxxx Xxxx.
