REPRESENTATIONS AND WARRANTIES OF BEN

​

BEN represents and warrants to AUMN, as of the date of this Agreement and as at Closing, as follows and acknowledge that AUMN is relying on such representations and warranties in connection with its sale to BEN of the Silex Shares and its completion of the other transactions contemplated herein:

​

​

BEN is duly incorporated and organized and validly subsisting under the laws of the Province of British Columbia and has all requisite corporate power, capacity and authority to enter into this Agreement, carry out the transactions contemplated by this Agreement, and to otherwise carry on its business as presently conducted.  

​

This Agreement has been duly authorized, executed and delivered by BEN and is a legal, valid and binding obligation of BEN enforceable against it in accordance with its terms subject to:

There is no bankruptcy, insolvency, liquidation, winding-up or other similar proceeding in progress, pending or threatened by or against BEN before any court or regulatory or administrative agency, authority or tribunal.

BEN has or prior to the Closing will have, the legal power, capacity and competence and has or will have obtained all necessary approvals by its directors, shareholders partners and others, including all Governmental Authority and third parties, and has or will have taken all other necessary corporate and other actions and proceedings to authorize the entering into and execution of this Agreement and the taking of all actions required pursuant hereto;

There are no current, pending, or, to the knowledge of BEN, threatened, actions, claims, demands, lawsuits, assessments, arbitrations, judgments, awards, decrees, orders, injunctions, prosecutions and investigations, or other proceedings, of, by, against, or relating to, BEN, which would affect BEN’s ability to complete the transactions contemplated in this Agreement or have a Material Adverse Effect on BEN, and BEN is not aware of any basis for any such action, claim, demand, lawsuit, prosecution, assessment, arbitration, investigation or other proceeding.

​

There is no authorization, license, approval, consent, order or any other action or, or any registration, declaration, filing or notice with or to any Governmental Authority, court, board or arbitrator that is required for the execution or delivery by BEN of this Agreement, or the completion or performance by BEN of any of the transactions contemplated by this Agreement, or the validity or enforceability of this Agreement against BEN, other than the conditional approval of the TSXV.

The execution, delivery and performance by BEN of this Agreement and any documents contemplated hereunder and the consummation of the transactions contemplated hereby and thereby, do not and will not: (a) conflict with or result in a violation or breach of, or default under, any provision of the articles of incorporation, by-laws, or other organizational documents of BEN; (b) conflict with or result in a violation or breach of any provision of any Law or Governmental Order applicable to BEN; or (c) require the consent, notice or other action by any Person under any Contract to which BEN is a party.

To the best of BEN’s knowledge, none of the funds to pay the Purchase Price have been or will be derived directly or indirectly from or related to any activity that is deemed criminal under the laws of Canada, the United States of America, or any other jurisdiction, or are being tendered on behalf of a Person who has not been identified to BEN.

Any investigation pursuant to this section shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of Silex and the Assets.

From the date hereof until the Closing, each Party hereto shall use commercially reasonable efforts to take such actions as are necessary to expeditiously satisfy the closing conditions set forth in this Agreement.

To the extent that any such press release or public statement is required by applicable Regulations or by a Governmental Authority, the press release

​

or public announcement shall be issued or made after consultation with the other Party and after taking into account the other Party’s comments.

BEN shall, at its own expense, timely file any tax return or other document with respect to such Taxes or fees (and AUMN shall cooperate with respect thereto as necessary).

From the date of this Agreement until the earlier of Closing and the termination of this Agreement in accordance with Article 9, AUMN and Silex will not, directly or indirectly, through any officer, director, agent, affiliate, employee, advisor (“Representatives”) or otherwise: (i) solicit or initiate the submission of any proposal (other than the transactions contemplated herein) or offer from any Person relating to any acquisition of Silex and/or the Assets, or other similar transaction or business combination involving the business of Silex and/or the Assets (an “Alternative Transaction”), or (ii) participate in any negotiations or discussions regarding or furnish to any other Person any information with respect to, or otherwise cooperate in any way with or facilitate, any effort or attempt by any other Person to do or seek such Alternative Transaction.

Subject to the other terms and conditions of this Article 8, AUMN shall defend, indemnify and hold harmless BEN, their Affiliates and their respective stockholders, directors, officers and employees from and against all claims, judgments, damages, liabilities, settlements, Losses, costs and expenses, including legal fees and disbursements, arising from or relating to:

​

Whenever any claim shall arise for indemnification hereunder, the party entitled to indemnification (the “Indemnified Party”) shall promptly provide written notice of such claim to the other party (the “Indemnifying Party”). In connection with any claim giving rise to indemnity hereunder resulting from or arising out of any action by a Person who is not a party to this Agreement, the Indemnifying Party, at its sole cost and expense and upon written notice to the Indemnified Party, may assume the defense of any such action with counsel reasonably satisfactory to the Indemnified Party. The Indemnified Party shall be entitled to participate in the defense of any such action, with its counsel and at its own cost and expense. If the Indemnifying Party does not assume the defense of any such action, the Indemnified Party may, but shall not be obligated to, defend against such action in such manner as it may deem appropriate, including, but not limited to, settling such action, after giving notice and details of the proposed settlement to the Indemnifying Party, on such terms as the Indemnified Party may deem appropriate and no action taken by the Indemnified Party in accordance with such defense and settlement shall relieve the Indemnifying Party of its indemnification obligations herein provided with respect to any damages resulting therefrom. The Indemnifying Party shall not settle any action without the Indemnified Party’s prior written consent (which consent shall not be unreasonably withheld or delayed).

​

All indemnification payments made by either Party under this Agreement shall be treated by the Parties as an adjustment to the Purchase Price for tax purposes, unless otherwise required by law.

​

From and after the Closing, and except in the case of fraud, the sole and exclusive monetary remedy for any breach or failure to be true and correct, of any representation or warranty or any covenant or agreement in this Agreement shall be indemnification in accordance with this Article 8. In furtherance of the foregoing, each of the Parties hereby waives, from and after the Closing to the fullest extent permitted by law, any and all other rights, claims and causes of action known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against any BEN or AUMN, as the case may be, arising under or based upon any federal, state, provincial or local law (including any such law relating to environmental matters or arising under or based upon any securities law, common law or otherwise). Notwithstanding the foregoing, this Section 8.5 shall not operate to limit the rights of the Parties to seek equitable remedies (including specific performance or injunctive relief).

​

This Agreement may be terminated at any time prior to the Closing:

​

Subject to the limitations and other provisions of this Agreement, the representations and warranties contained herein shall survive the Closing and shall remain in full force and effect until the date that is twelve (12) months from the Closing Date. All covenants and agreements of the Parties contained herein which by their terms are to be performed after Closing shall survive the Closing in accordance with their respective terms. Notwithstanding the foregoing, any claims asserted in good faith with reasonable specificity (to the extent known at such time) and in writing by notice from the non-breaching Party to the breaching Party prior to the expiration date of the applicable survival period shall not thereafter be barred by the expiration of such survival period and such claims shall survive until finally resolved.

El Quevar Property Description

​

The El Quevar Project is located in northwestern Argentina, approximately 300 km northwest of the provincial capital of Salta, within the San Antonio de los Cobres municipality, Salta Province (Figure 1). The Project is located close to geographic coordinates 24.3° south latitude and 66.8° west longitude. The 1994 Argentinian Zone 3 GCS POSGAR coordinates for the Yaxtché zone are approximately 3,418,000 E and 7,307,000 N. The El Quevar Project consists of thirty-one (31) mining concessions (approx. 57,000 ha) (Table 1, Figure 2) and seven (7) easements (Table 2). Mining concessions and easements are held in the name of Silex Argentina S.A. (Silex Argentina). Mining concessions are granted in perpetuity as long as the mining protection conditions are met. The easements remain in force while the mining concession to which they serve subsists. Surface rights at the El Quevar Project are owned by the province of Salta.
