(b)   Subject at all times to the workplace rules and supervision of Newco, and provided any rights of access do not interfere with any exploration, development, mining or processing work conducted on the Mining Properties, Primero and STB hereby grants, and agrees that each of them shall cause Newco to grant, to SWC and its representatives, at reasonable times and upon reasonable notice and at SWC’s sole risk and expense, the right to access the Mining Properties, the Mineral Processing Facility and any other facility owned or operated by Newco or any of its Affiliates where Minerals are milled or processed, and Primero and Newco’s personnel, in each case to monitor Newco’s silver mining and processing operations on the Mining Properties and to prepare technical reports in accordance with NI 43-101.

(c)   Each of Primero and STB shall, from the Reference Date and during the remainder of the Term, do and cause to be done all things necessary to (1) maintain each of their respective and Newco’s corporate existence and, (2) in the case of STB, remain a Barbados resident corporation, and in the case of Newco, remain a Mexican resident corporation and not become a resident in Canada for tax purposes pursuant to the Income Tax Act (Canada).  To the extent that STB is obligated to withhold, deduct, charge or levy any taxes, duties, assessments or governmental charges of whatever nature in respect of any deliveries of Refined Gold made hereunder after the Reference Date as a result of

- 29 -

any breach of this Section 12(c), then STB shall pay or deliver to SWC, in addition to such deliveries, such additional deliveries or payments as are necessary to ensure that the net amount received by SWC (free and clear and net of any such taxes, duties, assessments or governmental charges, including any of the foregoing required to be deducted, withheld, charged or levied on any such additional amounts) equal to the full amount SWC would have received had no such deductions, withholding, charge or levy been required.

(d)   Subject to Sections 6(g) and 16(c), the Permitted Encumbrances and the Encumbrances granted to SWC and Goldcorp, Primero and STB shall cause Newco to be the only owner (or lessee with respect to leased assets) of all of the assets, property and undertaking used or acquired for use in connection with the San Dimas Mine (other than the employees employed at the San Dimas Mine), including the Mining Properties, the San Dimas Mining Lots and the Mineral Processing Facility, and shall ensure that no other person (other than a lessor with respect to leased assets) holds or acquires any ownership right, title or interest in or to such assets, property and undertaking.

(e)   Primero and STB shall ensure that Newco does not abandon any of the Mining Properties or allow or permit any of the Mining Properties to lapse or cease conducting mining operations or activities on the Mining Properties, unless Primero and STB provide evidence satisfactory to SWC, acting reasonably, that it is not economical to mine Minerals from the Mining Properties that they propose to abandon or let lapse.

(f)   Primero and STB shall cause Minerals to not be stockpiled for more than 10 days before the end of each Contract Year.

13.Right of First Refusal

(a)   If, at any time and from time to time during the Term, Primero, STB, Newco or any of their respective Affiliates (the “Vendor”) receives a definitive offer from a third party (other than an Affiliate of the Vendor which enters into an agreement in favour of SWC, in form and substance satisfactory to SWC, acting reasonably, whereby such Affiliate agrees to assume, perform and be bound by the obligations of the Vendor set out in this Section 13) that would be binding upon acceptance by the Vendor to purchase a Primero ROFR Interest (a “Third Party Offer”), and the Vendor is willing to accept that Third Party Offer, then Primero shall cause the Vendor, by notice in writing delivered to SWC, to offer to sell all, but not less than all, of the Primero ROFR Interest so sought to be purchased by the third party under the Third Party Offer to SWC at the same price and otherwise upon the same terms and conditions as are contained in the Third Party Offer, together with best available information that the Vendor and any of its Affiliates has with respect to the Primero ROFR Interest (including any information provided to the third party bidder) (the “ROFR Offer”); provided that, if the Third Party Offer includes non-cash consideration that is personal to the third party (including shares of the third party), then SWC shall be entitled to substitute such non-cash consideration with non-cash consideration that is personal to SWC with the same or greater value, liquidity and marketability as the third party’s non-cash consideration; and further provided that, if the

- 30 -

Third Party Offer includes the purchase of any asset other than a Primero ROFR Interest from Vendor, then the ROFR Offer shall similarly include such other assets.

(b)   SWC may, within 30 days from the date of delivery of the ROFR Offer, accept the ROFR Offer by notice in writing delivered to the Vendor, in which event it shall then become a binding agreement of purchase and sale between SWC and the Vendor at the price and upon the terms and conditions contained in the ROFR Offer; provided that, if so elected by SWC in its acceptance notice, SWC may require that the terms and conditions contained in the ROFR Offer be amended to require that metal sales and deliveries be sold and delivered to SWC by STB (rather than the Vendor) pursuant to a transaction structure substantially similar to the transaction structure contemplated by this Agreement.

(c)   If SWC does not accept the ROFR Offer, then the Vendor shall be free to sell all (but not less than all) of such Primero ROFR Interest to the applicable third party pursuant to the Third Party Offer.  If the Vendor and the third party have not entered into a binding, written agreement pertaining to all (but not less than all) of such Primero ROFR Interest (the “Third Party Agreement”) within 90 days of the expiry of the 30-day period set forth in Section 13(b), then Primero and the Vendor shall again be required comply with the terms of this Section 13 with respect to that Third Party Offer before selling the Primero ROFR Interest that is the subject to the Third Party Offer to a third party.  Primero shall provide SWC with a copy of the Third Party Agreement promptly once it is executed and delivered, and shall execute and deliver to SWC at the completion of the transactions contemplated by the Third Party Agreement a certificate of a senior officer Primero certifying that the sale of the Primero ROFR Interest to the Third Party was completed pursuant to the terms of the Third Party Offer.

(d)   For the avoidance of doubt:

(i)    this Section 13 is intended to apply, mutatis mutandis, to any offer made by a Vendor to any third party to sell a Primero ROFR Interest, with such changes as are necessary to make this Section 13 applicable; and

(ii)   a Vendor shall be entitled at any time to negotiate with any third party the terms upon which such third party may purchase a Primero ROFR Interest, provided that before such terms are accepted, the Vendor complies with this Section 13.

(xiii)   any defence arising by reason of any failure by STB to obtain, perfect or maintain a perfected or prior (or any) security interest in or lien or encumbrance upon any property of SWC or any other person, or by reason of any interest of STB in any property, whether as owner thereof or the holder of a security interest therein or lien or encumbrance thereon, being invalidated, voided, declared fraudulent or preferential or otherwise set aside, or by reason of any impairment by STB of any right to recourse or collateral;

(xiv)  any defence arising by reason of the failure of STB to marshal any property;

 - 40 -

(xv)  any defence based upon any failure of STB to give to SWC or SLW notice of any sale or other disposition of any property securing any SWC Obligations or any guarantee thereof, or any defect in any notice that may be given in connection with any sale or other disposition of any such property, or any failure of STB to comply with any applicable law in enforcing any security interest in or lien upon any such property, including any failure by STB to dispose of any such property in a commercially reasonable manner;

(xvi)  any dealing whatsoever with SWC or any other person or any security, whether negligently or not, or any failure to do so;

(xvii)  any defence based upon or arising out of any bankruptcy, insolvency, reorganization, moratorium, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against SWC or any other person, including any discharge of, or bar against collecting, any SWC Obligations, in or as a result of any such proceeding; or

(xviii)  any other act or omission to act or delay of any kind by SWC, STB or any other person or any other circumstance whatsoever, whether similar or dissimilar to the foregoing, which might, but for the provisions of this paragraph (f), constitute a legal or equitable discharge, limitation or reduction of the obligations of SLW hereunder (other than the payment or performance in full of all of the SWC Obligations).  The foregoing provisions of this paragraph (f) apply (and the waivers set out therein will be effective) even if the effect of any action (or failure to take action) by STB is to destroy or diminish any subrogation rights of SLW or any rights of SLW to proceed against SWC for reimbursement or to recover any contribution from any other guarantor or any other right or remedy of SLW.

(g)   STB shall not be bound to exhaust its recourse against SWC or any other persons or to realize on any securities it may hold in respect of the SWC Obligations before being entitled to payment or performance from SLW under this Section 20 and SLW hereby renounces all benefits of discussion and division.

21.Events of Default

(a)   Each of the following events or circumstances constitutes an event of default by STB (each, an “Event of Default”):

(i)   STB fails to sell and deliver Refined Silver to SWC on the terms and conditions set forth in this Agreement within 10 Business Days of receipt of notice from SWC notifying STB of such default;

(ii)  Primero is in breach or default of any of its covenants or obligations set forth in Section  19;

(iii) any Primero Entity is in breach or default of any of its covenants or obligations set forth in this Agreement or any Security Agreement in any material respect (other than a breach or default of the covenants and obligations referenced in

- 41 -

Sections 21(a)(i) and 21(a)(ii) above or a breach or default of Section 3(b), which breach or default shall not constitute an Event of Default), and such breach or default is not remedied within the Cure Period;

(iv) any of the representations or warranties given by any Primero Entity in this Agreement or any Security Agreement is inaccurate in any material respect as of the date given, and such inaccuracy is not remedied within the Cure Period;

(v)  Newco does not observe and perform any covenant or obligation that Primero or STB are required to cause Newco to observe or perform under this Agreement or that otherwise relates to Newco, in any material respect, and such non-observance or non-performance is not remedied within the Cure Period;

(vi)     the Silver Wheaton Security shall not constitute first prior ranking charges and security interests in, to and upon the Collateral, subject only to Permitted Encumbrances and the registration of the Silver Wheaton Security in accordance with Section 6;

(vii) upon the occurrence of a Lender Event affecting any Primero Entity; and

(viii)   upon the occurrence of an Insolvency Event affecting any Primero Entity.

(b)   If an Event of Default occurs and is continuing, SWC shall have the right, upon written notice to STB, at its option and in addition to and not in substitution for any other remedies available at law or equity, to take any or all of the following actions:

(i)    demand all amounts owing by Primero and STB to SWC pursuant to this Agreement, including pursuant to Section 19(b);

(ii)      terminate this Agreement and demand any and all Losses resulting or arising from the occurrence of such Event of Default and termination, including a net present value calculation of the Refined Silver that would have been delivered by STB to SWC hereunder but for the occurrence of such Event of Default.  The net present value calculation of Refined Silver shall be based on reasonable assumptions and forecasts with respect to the applicable discount rates to use, the applicable metal prices to use, and the reasonably expected Payable Silver that would have been sold and delivered to SWC hereunder but for the occurrence of such Event of Default (based on, among other factors, the Reserves and Resources (as such terms are defined in NI 43-101), inferred resources and potential exploration success, the expected throughput through the Mineral Processing Facility and expected metal recoveries).  Upon demand from SWC, STB shall promptly pay all such Losses to SWC; and

(iii)   enforce the Silver Wheaton Security, subject to the inter-creditor agreements entered into pursuant to Section 6(d).

22.General Provisions

(b)   In the event that a new tax law is enacted, or there shall occur any revision in, implementation of, amendment to or interpretation of any tax law, in each case that has an adverse effect on any of the Parties or any of their Affiliates in respect of the transactions contemplated by this Agreement, then Primero and STB on the one hand, and SWC and SLW on the other hand, agree that they shall negotiate in good faith with each other to amend this Agreement so that the other Parties or their Affiliates are no longer adversely affected by any such enactment, revision, implementation, amendment or interpretation, as the case may be; provided that any amendment to this Agreement shall not have any adverse impact on STB or its Affiliates on the one hand, and SWC or its Affiliates on the other hand.

(c)   Nothing herein shall be construed to create, expressly or by implication, a joint venture, mining partnership, commercial partnership, or other partnership relationship between SWC and STB or Primero.

(d)   This Agreement shall be governed by and construed under the laws of the Province of Ontario and the laws of Canada applicable therein (without regard to its laws relating to any conflicts of laws). The United Nations Vienna Convention on Contracts for the International Sale of Goods shall not apply to this Agreement.

(e)   Time is of the essence in this Agreement.

(f)   If any provision of this Agreement is wholly or partially invalid, this Agreement shall be interpreted as if the invalid provision had not been a part hereof so that the invalidity shall not affect the validity of the remainder of the Agreement which shall be construed as if the Agreement had been executed without the invalid portion.  It is hereby declared to be the intention of the Parties that this Agreement would have been executed without reference to any portion which may, for any reason, hereafter be declared or held invalid.
