Each of Peregrine and the Peregrine Subsidiaries shall cooperate, and shall cause their respective affiliates, officers, employees, agents, auditors and representatives reasonably to cooperate, in preparing and filing all Tax Returns, resolving all disputes and audits with respect to all taxable periods relating to Taxes, and in any other matters relating to Taxes, including by maintaining and making available to Stillwater all books, records and other information of Peregrine and the Peregrine Subsidiaries related to Taxes and shall timely pay all Taxes arising before the Effective Date.

Covenants of Peregrine Regarding Non-Solicitation

4.2 (a)

Peregrine shall, and Peregrine shall direct and cause its representatives and the Peregrine Subsidiaries and their respective representatives to, immediately cease and cause to be terminated any solicitation, encouragement, activity, discussion, negotiation or process with any Person that may be ongoing with respect to any proposal that constitutes, or may reasonably be expected to constitute, an Acquisition Proposal whether or not initiated by Peregrine or any of the Peregrine Subsidiaries. Peregrine further agrees not to release any such Person from any standstill or confidentiality agreement or provision to which such Person is a party with Peregrine or any of the Peregrine Subsidiaries and to take all required actions to enforce such standstill and confidentiality agreements and provisions.

(b)

Subject to subsection 4.2(c) hereof and section 4.3 hereof, Peregrine hereby covenants and agrees that it shall not, and Peregrine shall not authorize or permit any of the Peregrine Subsidiaries, and Peregrine shall not authorize or permit any of the representatives of Peregrine or of any of the Peregrine Subsidiaries, directly or indirectly, to:

(i)

make, solicit, initiate, encourage, entertain, promote or facilitate, including by way of furnishing information, permitting any visit to facilities or properties of Peregrine or any of the Peregrine Subsidiaries or entering into any form of agreement, written or verbal, any inquiries or the making of any proposal which does or could constitute an Acquisition Proposal or potential Acquisition Proposal;

44.

(ii)	participate, directly or indirectly, in any discussions or negotiations regarding any Acquisition Proposal or potential Acquisition Proposal;

(iii)

withdraw, modify, qualify or change in a manner adverse to Stillwater, or publicly state that it intends to withdraw, modify, qualify or change in a manner adverse to Stillwater, the approval or recommendation of the Peregrine Board of the Arrangement (it being understood that failing to affirm the approval or recommendation of the Peregrine Board of the Arrangement after an Acquisition Proposal has been publicly announced shall be considered a modification which is adverse to Stillwater for the purposes of this subsection if the Peregrine Board has not affirmed the approval or recommendation of the Arrangement on the date which is the earlier of (A) 10 calendar days after the date on which the Acquisition Proposal has been publicly announced and (B) five Business Days prior to the Peregrine Meeting);

(iv)	approve or recommend any Acquisition Proposal; or

(v)

enter into any agreement, written or verbal, related to any Acquisition Proposal or requiring Peregrine to abandon, terminate or fail to consummate the Arrangement or any other transaction contemplated herein or providing for the payment of any break, termination or other fee or expense to any Person in the event that Peregrine or any of the Peregrine Subsidiaries completes the Arrangement and the other transactions contemplated herein or any other transaction with Stillwater or the Stillwater Subsidiaries agreed to prior to the termination of this Agreement.

None of Peregrine or any Peregrine Subsidiary shall, directly or indirectly, consider, discuss, negotiate, accept, approve or recommend an Acquisition Proposal or provide information to any Person proposing an Acquisition Proposal, in each case after the date of the approval of the Arrangement by the Peregrine Shareholders.

(c)

Notwithstanding subsection 4.2(b) hereof or any other provision of this Agreement, the Peregrine Board may, prior to the approval of the Arrangement Resolution by the Peregrine Shareholders, consider and participate, directly or indirectly, in any discussions or negotiations with, or provide information to, or permit any visit to the properties or facilities of Peregrine or any of the Peregrine Subsidiaries by, any Person who has delivered a bona fide written Acquisition Proposal:

(i)	which was not solicited or encouraged after the date of this Agreement;

(ii)	did not otherwise result from a breach of this section 4.2; and

(iii)

that the Peregrine Board determines in good faith, after consultation with a Financial Advisor and outside legal counsel, is or would, if completed, reasonably be expected to constitute, a Superior Proposal;

45.

provided, however, that prior to taking any such action, Peregrine must;

(iv)	give notice to Stillwater of such Acquisition Proposal as provided in subsection 4.2(d) hereof; and

(v)

obtain a confidentiality agreement from the Person making such Acquisition Proposal that is substantively the same as the Confidentiality Agreement, and containing terms no more favourable to such Person than the Confidentiality Agreement including a standstill provision at least as stringent as that contained in the Confidentiality Agreement.

If Peregrine or any of the Peregrine Subsidiaries receives a request for material non-public information from a Person who has made an unsolicited bona fide written Acquisition Proposal and Peregrine is permitted, as contemplated under this subsection 4.2(c), to consider and participate, directly or indirectly, in any discussions or negotiations with, or provide information to, or permit any visit to the properties or facilities of Peregrine or any of the Peregrine Subsidiaries, subject to the execution by such Person of the confidentiality agreement as described above, provide such Person with such information and access; provided that Peregrine sends a copy of any such confidentiality agreement to Stillwater promptly upon its execution and Stillwater is provided with a list of, and a copy of, the information provided to such Person (if not previously provided with such information) and is immediately provided with access to similar information to which such Person is provided (if not previously provided with such access).

(d)

From and after the date of this Agreement, Peregrine shall promptly (and in any event within 24 hours) notify Stillwater, at first orally and then in writing, of any inquiry, proposal or offer relating to or constituting an Acquisition Proposal, or any request for non-public information relating to Peregrine or any of the Peregrine Subsidiaries. Such notice shall include a description of the terms and conditions of any such proposal, inquiry or offer, the identity of the Person making such proposal, inquiry or offer and provide such other details of the proposal, inquiry or offer as Stillwater may reasonably request. Peregrine shall keep Stillwater fully informed on a prompt basis of the status, including any change to the material terms, of any such inquiry, proposal or offer.

(e)

Nothing contained in subsection 4.2(b) above shall prohibit the Peregrine Board from taking any action prohibited by subsection 4.2(b)(iii), if the Peregrine Board determines, in good faith (after consultation with outside legal counsel) that such action or inaction is necessary for the Peregrine Board to act in a manner consistent with its fiduciary duties or Applicable Laws, provided that Peregrine may not proceed with the announcement of such decision before giving written notice of such decision to Stillwater. The foregoing shall not relieve Peregrine from its obligation to proceed to call and hold the Peregrine Meeting and to hold a vote of the Peregrine Shareholders on the Arrangement Resolution, except in circumstances where this Agreement is terminated in accordance with the terms hereof prior to the date of the Peregrine Meeting.

(f)

Peregrine shall ensure that each of its officers and directors and the Peregrine Subsidiaries and their respective officers and directors and all advisors and representatives retained by any of them are aware of the provisions of this section 4.2, and it shall be responsible for any breach of this section 4.2 by such officers, directors, advisors or representatives.

46.

Right to Accept a Superior Proposal

4.3 (a)

If Peregrine and the Peregrine Subsidiaries have complied with section 4.2 of this Agreement with respect thereto, Peregrine may accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Superior Proposal prior to the approval of the Arrangement Resolution by the Peregrine Shareholders and terminate this Agreement if, and only if (with the exception of a confidentiality agreement which complies with section 4.2 hereof the execution of which shall not be subject to the conditions of this section 4.3):

(i)	Peregrine has provided Stillwater with a copy of the document containing the Superior Proposal;

(ii)

five Business Days have elapsed from the later of (A) the date Stillwater received written notice (a “Superior Proposal Notice”) advising Stillwater that the Peregrine Board has resolved, subject only to compliance with this section 4.3, to accept, approve, recommend or enter into an agreement in respect of such Superior Proposal, specifying the terms and conditions of such Superior Proposal and identifying the Person making such Superior Proposal, and (B) the date Stillwater received a copy of the document containing such Superior Proposal;

(iii)

the Peregrine Board has determined in good faith (after consultation with outside legal counsel) that it is necessary for the Peregrine Board to take such action in order to discharge properly its fiduciary duties;

(iv)

such Superior Proposal does not provide for the payment of any break, termination or other fee or expense to the Person making the Superior Proposal in the event that Peregrine or any of the Peregrine Subsidiaries completes the Arrangement and the other transactions contemplated in this Agreement or any other transaction with Stillwater or the Stillwater Subsidiaries agreed to prior to the termination of this Agreement,

(v)	taking into account any revised proposal made by Stillwater since receipt of the Superior Proposal Notice, such Superior Proposal remains a Superior Proposal and the Peregrine Board has again made the determinations referred to in this subsection 4.3(a); and

(vi)	Peregrine has previously or concurrently paid or caused to be paid to Stillwater the Termination Fee payable in accordance with section 7.3 of this Agreement.

In the event that Peregrine provides Stillwater with a Superior Proposal Notice on a date that is less than five Business Days prior to the Peregrine Meeting, Peregrine shall adjourn the Peregrine Meeting to a date that is not less than five Business Days and not more than 10 Business Days after the date of receipt by Stillwater of the Superior Proposal Notice.

47.

(b)

During the five Business Day period referred to in paragraph 4.3(a)(ii) above, Stillwater shall have the right, but not the obligation, to offer to amend the terms of this Agreement. The Peregrine Board will review any proposal by Stillwater to amend the terms of this Agreement in good faith in order to determine whether Stillwater’s amended proposal upon acceptance by Peregrine would result in such Superior Proposal ceasing to be a Superior Proposal. If the Peregrine Board so determines, Peregrine shall enter into an amended agreement with Stillwater reflecting Stillwater’s amended proposal. If the Peregrine Board continues to believe, in good faith and after consultation with the Financial Advisor and outside legal counsel, that such Superior Proposal remains a Superior Proposal and therefore rejects Stillwater’s amended proposal, Peregrine may, on termination of this Agreement in accordance with section 7.1 hereof and payment of the Termination Fee as required pursuant to section 7.3 hereof, accept, approve, recommend or enter into an agreement, understanding or arrangement in respect of such Superior Proposal.

(c)

Peregrine hereby acknowledges and agrees that each successive material modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of section 4.2 hereof and the requirement under paragraph 4.3(a)(ii) hereof to initiate an additional five Business Day notice period.

(d)

If the Peregrine Information Circular has been sent to the Peregrine Shareholders prior to the expiry of the five Business Day period set forth in subsection 4.3(a) hereof and, during such period, Stillwater requests in writing that the Peregrine Meeting proceed, unless otherwise ordered by the Court, Peregrine shall continue to take all reasonable actions necessary to hold the Peregrine Meeting and to cause the Arrangement to be voted on at the Peregrine Meeting provided that such obligation shall cease to apply upon termination of this Agreement in accordance with section 7.1 hereof and payment of the Termination Fee, if applicable, pursuant to section 7.3 hereof.

Covenants of Peregrine Regarding Reorganization

4.4

Subject to applicable Laws, Peregrine and the Peregrine Subsidiaries shall effect only such reorganizations of the business, operations and assets of Peregrine and the Peregrine Subsidiaries or such other transactions as Stillwater may request, acting reasonably (each a “Pre-Acquisition Reorganization”), and co-operate with Stillwater and its advisors in order to determine the nature of any Pre-Acquisition Reorganization that might be undertaken and the manner in which they might most effectively be undertaken; provided, however, that any Pre-Acquisition Reorganization: (i) will not require Peregrine to obtain the prior approval of the Peregrine Shareholders in respect of such Pre-Acquisition Reorganization other than at the Peregrine Meeting; (ii) will not impede or materially delay the completion of the Arrangement; (iii) will not result in the withdrawal or material modification of the valuation by Peregrine’ Financial Adviser; and (iv) cannot either be completed immediately prior to or contemporaneously with the Effective Time, or cannot be reversed or unwound, without materially adversely affecting Peregrine, the Peregrine Subsidiaries or the Peregrine Shareholders. Stillwater shall provide written notice to Peregrine of any proposed Pre-Acquisition Reorganization at least ten Business Days prior to the Effective Time. Upon receipt of such notice, Stillwater and Peregrine shall, if Peregrine is required to do so pursuant to the immediately preceding sentence, work co-operatively and use commercially reasonable efforts to prepare prior to the Effective Time all documentation necessary and do all such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganization at least two Business Days prior to the Effective Time, or such later time as may be agreed to by Stillwater. In addition:

48.

(a)

Stillwater shall reimburse Peregrine for all direct or indirect costs and liabilities of Peregrine and its Subsidiaries, including employment costs, Taxes and liabilities as well as any costs, Taxes and liabilities that may be incurred in accordance with this Section 4.4 (including actual out-of-pocket costs and expenses for filing fees and external counsel and any costs of unwinding a Pre-Acquisition Reorganization);

(b)

any Pre-Acquisition Reorganization or required cooperation of Peregrine in structuring, planning and implementing any Pre-Acquisition Reorganization shall not unreasonably interfere in material operations prior to the Effective Time of Peregrine or any Peregrine Subsidiary (it being understood that any combination of the business, operations or assets of Peregrine or any of the Peregrine Subsidiaries with the business, operations or assets of one or more other Peregrine Subsidiaries by way of amalgamation, merger, winding-up or otherwise shall not be considered to unreasonably interfere in material operations);

(c)	unless the Parties otherwise agree, any Pre-Acquisition Reorganization shall not require any pre-approval from any Governmental Entity; and

(d)	any Pre-Acquisition Reorganization shall not require Peregrine or any Peregrine Subsidiary to contravene any applicable Laws or any material contract.

Stillwater acknowledges and agrees that the planning for and implementation of any Pre-Acquisition Reorganization shall not be considered a breach of any covenant under this Arrangement Agreement and shall not be considered in determining whether a representation or warranty of Peregrine hereunder has been breached. Stillwater and Peregrine shall work cooperatively and use reasonable commercial efforts to prepare prior to the Effective Time all documentation necessary and do such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganization.

(iii)

After the Effective Time and until surrendered as contemplated by paragraph 5(c)(i) hereof, each certificate which immediately prior to the Effective Time represented one or more Peregrine Shares shall be deemed at all times to represent only the right to receive in exchange therefor a certificate representing the Share Consideration and the Cash Consideration to which the holder of such certificate is entitled to receive in accordance with paragraph 5(c)(i) hereof.

(d)

Lost Certificates. In the event that any certificate which immediately prior to the Effective Time represented one or more Peregrine Shares which were exchanged for Stillwater Shares in accordance with section 3 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, certificates representing the Stillwater Shares and Cash Consideration which such Peregrine Shareholder is entitled to receive in accordance with section 3 hereof. When authorizing such delivery of certificates representing the Stillwater Shares and the Cash Consideration which such Peregrine Shareholder is entitled to receive in exchange for such lost, stolen or destroyed certificate, the Peregrine Shareholder to whom certificates representing such Stillwater Shares and Cash Consideration are to be delivered shall, as a condition precedent to the delivery of such Stillwater Shares and the Cash Consideration, give a bond satisfactory to Stillwater, AcquireCo, Peregrine and the Depositary in such amount as Stillwater, AcquireCo, Peregrine and the Depositary may direct, or otherwise indemnify Stillwater, AcquireCo, Peregrine and the Depositary in a manner satisfactory to Stillwater, AcquireCo, Peregrine and the Depositary, against any claim that may be made against Stillwater, AcquireCo, Peregrine 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 by-laws of Stillwater, AcquireCo and Peregrine as the case may be.

(e)

Dividends or other Distributions. No dividends or distributions declared or made after the Effective Date with respect to Stillwater Shares with a record date after the Effective Date will be payable or paid to the holder of any unsurrendered certificate or certificates which, immediately prior to the Effective Date, represented outstanding Peregrine Shares unless and until the holder of such certificate shall have complied with the provisions of this section 5. Subject to applicable law and to section 5 hereof, at the time of such compliance, there shall, in addition to the delivery of a certificate representing the Stillwater Shares to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of the dividend or other distribution with a record date after the Effective Time theretofore paid with respect such Stillwater Shares.

(f)

Termination of Rights. Any certificate formerly representing Peregrine Shares that is not deposited, with all other documents as provided in this section 5 on or before the sixth anniversary of the Effective Date, shall cease to represent any claim or interest of any kind or nature (including, without limitation dividends or distributions set out in section 5(d) hereof) against Stillwater, AcquireCo, Peregrine or the Depositary.

(g)

Withholding Rights. Stillwater, AcquireCo, Peregrine and the Depositary shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable to any person hereunder and from all dividends or other distributions otherwise payable to any Peregrine Shareholder such amounts as Stillwater, AcquireCo, Peregrine and the Depositary is required 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, in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the person in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority

IPEEM holds title to all of the Rio Cenicero concessions, and Minera Peregrine Argentina SA holds valid contractual and legal rights to conduct exploration for a term of five years, at the end of which Peregrine may decide to mine the properties. Payments of US$2,500 per month and US$1.7 million in total exploration expenditures until November 4, 2013 are required to maintain the agreement in good standing. If Peregrine decides to mine the Rio Cenicero concessions, it must execute a mining agreement with the IPEEM for 30 years (subject to extension by mutual agreement).
