Ladies/Gentlemen:

Silver Standard Resources Inc., a corporation organized and existing under the laws of British Columbia (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the several underwriters named in Schedule I hereto (the “Underwriters”) an aggregate of 5,450,000 common shares (the “Firm Shares”), without par value, and, for the sole purpose of covering over-allotments in connection with the sale of the Firm Shares, at the option of the Underwriters, up to an additional 817,500 common shares (the “Additional Shares”). The Firm Shares and any Additional Shares purchased by the Underwriters are referred to herein as the “Shares”. UBS Securities Canada Inc. is acting as lead manager (“UBS” or the “Lead Manager”) in connection with the offering and sale of the Shares contemplated herein (the “Offering”).

The Company understands that the Underwriters propose to make a public offering of the Shares in the United States and each of the provinces of Canada, except Quebec,

Any Shares sold by a Sub-Underwriter will be purchased by the Sub-Underwriter from its respective U.S. broker-dealer affiliate at the Closing Date (as defined below) at a price equal to the price set forth in Section 2(a) below or such purchase price less an amount to be mutually agreed upon by the Sub-Underwriter and its respective U.S. broker-dealer affiliate, which amount shall not be greater than the underwriting commission set forth in Annex IV hereto.

any Material Subsidiary is a party or by which the Company or any Material Subsidiary or their respective properties, operations or assets may be bound or (ii) violate or conflict with any provision of the certificate or articles of incorporation, by-laws, certificate of formation, limited liability company agreement, partnership agreement or other organizational documents of the Company or any Material Subsidiary, or (iii) violate or conflict with any statute, law, rule, regulation, ordinance, directive, judgment, decree or order of any judicial, regulatory or other legal or governmental agency or body, Canadian, U.S. or other, except (in the case of clauses (i) and (iii) above) as could not reasonably be expected to have a Material Adverse Effect.

(r) No Consent of, with or from any judicial, regulatory or other legal or governmental agency or body or any third party, Canadian, U.S. or foreign, is required for the execution, delivery and performance of this Agreement or consummation of the transactions contemplated by this Agreement, except the registration under the Securities Act of the Shares, the qualification of the Shares for distribution in the Canadian Jurisdictions as contemplated by this Agreement, necessary approvals of the Toronto Stock Exchange (the “TSX”), the filing of a Notification Form: Change in the Number of Outstanding Shares with the Nasdaq Stock Market (“Nasdaq”) and any consents as may be required under state or foreign securities or blue sky laws, or the by-laws and rules of the Financial Industry Regulatory Authority (“FINRA”) in connection with the purchase and distribution of the Shares by the Underwriters or the Sub-Underwriters, each of which has been obtained and is in full force and effect (on a conditional basis, in the case of the Consent of the TSX).

(s) Except as disclosed in the Registration Statement, the Pricing Prospectuses and the Prospectuses, there is no judicial, regulatory, arbitral or other legal or governmental proceeding or other litigation or arbitration, Canadian, United States or foreign, pending to which the Company or any Subsidiary is a party or of which any property, operations or assets of the Company or any Subsidiary is the subject which, individually or in the aggregate, if determined adversely to the Company or any Subsidiary, could reasonably be expected to have a Material Adverse Effect; to the Company’s knowledge, no such proceeding, litigation or arbitration is threatened or contemplated; and the defense of all such proceedings, litigation and arbitration against or involving the Company or any Subsidiary could not reasonably be expected to have a Material Adverse Effect.

(t) The consolidated financial statements, including the notes thereto, included or incorporated by reference in the Registration Statement, the Pricing Prospectuses and the Prospectuses present fairly, in all material respects, the financial position as of the dates indicated and the cash flows and results of operations for the periods specified of the Company and its consolidated Subsidiaries; except as otherwise stated in the Registration Statement, the Pricing Prospectuses and the Prospectuses, said consolidated financial statements have been prepared in conformity with Canadian generally accepted accounting principles applied on a consistent basis throughout the periods involved and have been reconciled to United States generally accepted accounting principles in accordance with Item 18 of Form 20-F under the Exchange Act. No other financial statements or supporting schedules are required to be included in the Registration Statement, the Pricing Prospectuses and the Prospectuses by Canadian Securities Laws, the Securities Act, the Exchange Act or the Rules and Regulations. The other

financial and statistical information included or incorporated by reference in the Registration Statement, the Pricing Prospectuses and the Prospectuses, including the selected consolidated financial data set forth under the captions “Selected Consolidated Financial Data” and “Capitalization” in the Pricing Prospectuses and the Prospectuses, present fairly the information included therein and have been prepared on a basis consistent with that of the financial statements that are included or incorporated by reference in the Registration Statement, the Pricing Prospectuses and the Prospectuses and the books and records of the Company.

(u) There has not been any reportable event (within the meaning of National Instrument 51-102 of the Canadian Securities Administrators) between the Company and its auditors.

(v) The statistical, industry-related and market-related data included in the Registration Statement, the Pricing Prospectuses and the Prospectuses are based on or derived from sources which the Company reasonably and in good faith believes are reliable and accurate, and such data agree with the sources from which they are derived.

(w) The common shares of the Company have been registered pursuant to Section 12(b) of the Exchange Act. The common shares of the Company are listed on the TSX and on the Nasdaq Global Market, and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the common shares of the Company under the Exchange Act or de-listing the common shares of the Company from the TSX or Nasdaq, nor has the Company received any notification that the Commission, the Canadian Qualifying Authorities, the TSX or Nasdaq is contemplating terminating such registration or listing.

(x) The Company and its Material Subsidiaries maintain a system of internal accounting and other controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accounting for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company believes that the Company’s and its Material Subsidiaries’ internal control over financial reporting is effective and the Company and its Material Subsidiaries are not aware of any material weakness in their internal control over financial reporting.

(y) Since the date of the latest audited consolidated financial statements included or incorporated by reference in the Pricing Prospectuses and the Prospectuses there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(z) The Company and its Subsidiaries maintain disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act and Canadian Securities Laws) that comply with the requirements of the Exchange Act and Canadian Securities Laws; such disclosure controls and procedures have been designed to ensure that

material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within those entities. Such disclosure controls and procedures are effective.

(aa) There is and has been no failure on the part of the Company or any of its directors or officers, in their capacities as such, to comply with any provision of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated in connection therewith, including, without limitation, Section 402 related to loans and Sections 302 and 906 related to certifications.

(bb) Neither the Company nor, to the Company’s knowledge, any of its affiliates (within the meaning of Rule 144 under the Securities Act) has taken, directly or indirectly, any action which constitutes or is designed to cause or result in, or which could reasonably be expected to constitute, cause or result in, the stabilization or manipulation of the price of any security to facilitate the sale or resale of the Shares.

(cc) Neither the Company nor, to the Company’s knowledge, any of its affiliates (within the meaning of Rule 144 under the Securities Act) has, prior to the date hereof, made any offer or sale of any securities which could be “integrated” (within the meaning of the Securities Act and the Rules and Regulations) with the offer and sale of the Shares pursuant to the Registration Statement.

(dd) The statements set forth in the Base Prospectuses under the captions “Description of Share Capital”, “Enforceability of Civil Liabilities”, “Risk Factors – Risks Related to our Common Shares – Under U.S. federal tax rules, we may be classified as a passive foreign investment company….” and “Risk Factors – Risks Related to our Common Shares – Enforcement of judgments or bringing actions outside the United States….”, in the Canadian Prospectus Supplement and the U.S. Prospectus Supplement under the captions “Certain income tax considerations for U.S. holders,” “Certain income tax considerations for Canadian holders” and “Enforceability of Civil Liabilities,” in the Canadian Prospectus Supplement under “Eligibility for Investment” and in the Registration Statement under “Part II - Indemnification”, insofar as such statements summarize legal matters, agreements, documents or proceedings discussed therein, are, in all material respects, accurate, complete and fair summaries of such legal matters, agreements, documents or proceedings.

(ee) There is no franchise, contract or other document of a character required to be described in the Registration Statement, the Pricing Prospectuses or the Prospectuses, or to be filed as an exhibit thereto, which is not described or filed as required; insofar as such descriptions summarize legal matters, agreements, documents or proceedings discussed therein, such descriptions are accurate and fair summaries of such legal matters, agreements, documents or proceedings.

(ff) The Company is subject to the reporting requirements of Section 13 of the Exchange Act and files periodic reports with the Commission. All conditions for use of Form F-10 to register the Shares under the Securities Act have been satisfied.

(hh) Except as disclosed in the Pricing Prospectuses and the Prospectuses, there are no contracts, agreements or understandings between the Company and any person that would give rise to a valid claim against the Company or any Underwriter or Sub-Underwriter for a brokerage commission, finder’s fee or other like payment in connection with the transactions contemplated by this Agreement or, to the Company’s knowledge, any arrangements, agreements, understandings, payments or issuance with respect to the Company or any of its officers, directors, shareholders, partners, employees, Subsidiaries or affiliates that may affect the Underwriters’ compensation as determined by FINRA.

(jj) Except as disclosed in the Pricing Prospectuses and the Prospectuses, (i) the Company and each Material Subsidiary owns or leases all such properties as are necessary to the conduct of its business as presently operated and as proposed to be operated as described in the Pricing Prospectuses and the Prospectuses; (ii) to the knowledge of the Company, it and the Material Subsidiaries have good and marketable title to all real property and good and marketable title to all personal property owned by them, in each case free and clear of any and all Liens except such as are described in the Pricing Prospectuses and the Prospectuses or such as do not (individually or in the aggregate) materially affect the value of such property or materially interfere with the use made or proposed to be made of such property by the Company and the Material Subsidiaries; and any real property and buildings held under lease or sublease by the Company and the Material Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material to, and do not materially interfere with, the use made and proposed to be made of such property and buildings by the Company and the Material Subsidiaries; and (iii) neither the Company nor any Material Subsidiary has received any notice of any claim adverse to its ownership of any real or personal property or of any claim against the continued possession of any real property, whether owned or held under lease or sublease by the

Company or any Material Subsidiary, except as could not reasonably be expected to have a Material Adverse Effect.

(kk) All interests in material mining claims, concessions, exploitation or extraction rights or similar rights (“Mining Claims”) that are held by the Company or any of its Material Subsidiaries are in good standing, are valid and enforceable, are free and clear of any material liens or charges, and no material royalty is payable in respect of any of them, except as disclosed in the Pricing Prospectuses and the Prospectuses. Except as disclosed in the Pricing Prospectuses and the Prospectuses, no other material property rights are necessary for the conduct of the Company’s business as described therein, and there are no material restrictions on the ability of the Company and its Material Subsidiaries to use, transfer or otherwise exploit any such property rights except as required by applicable law or as set forth in the agreements listed in Exhibit B hereto (collectively, the “Material Agreements”). Except as disclosed in the Pricing Prospectuses and the Prospectuses, the Mining Claims held by the Company or its Material Subsidiaries cover the properties required by the Company for the purposes described therein.

(ll) Except as disclosed in the Pricing Prospectuses and the Prospectuses, the information relating to estimates by the Company of the proven and probable reserves and the measured, indicated and inferred resources associated with its mineral property projects contained in the Pricing Prospectuses and the Prospectuses has been prepared in all material respects in accordance with National Instrument 43-101- “Standards of Disclosure for Mineral Projects.” The Company believes that all of the assumptions underlying such reserve and resource estimates are reasonable and appropriate, and that the projected production and operating results relating to its projects and summarized in the Pricing Prospectuses and the Prospectuses are achievable by the Company.

(mm) The Company and the Material Subsidiaries maintain insurance in such amounts and covering such risks as the Company reasonably considers adequate for the conduct of its business and the value of its properties and as is customary for companies engaged in similar businesses in similar industries, all of which insurance is in full force and effect, except where the failure to maintain such insurance could not reasonably be expected to have a Material Adverse Effect. There are no material claims by the Company or any Material Subsidiary under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause. The Company reasonably believes that it will be able to renew its existing insurance as and when such coverage expires or will be able to obtain replacement insurance adequate for the conduct of the business and the value of its properties at a cost that would not have a Material Adverse Effect.

(nn) The Company and each Subsidiary has accurately prepared and timely filed all U.S., Canadian and foreign tax returns that are required to be filed by it and has paid or made provision for the payment of all taxes, assessments, governmental or other similar charges, including without limitation, all sales and use taxes and all taxes which the Company or any Subsidiary is obligated to withhold from amounts owing to employees, creditors and third parties, with respect to the periods covered by such tax returns (whether or not such amounts are shown as due on any tax return), except in any such case as could not reasonably be expected to have a Material Adverse Effect. No deficiency assessment with respect to a proposed adjustment

of the Company’s or any Subsidiary’s Canadian federal and provincial, U.S. federal and state, local or foreign taxes is pending or, to the best of the Company’s knowledge, threatened. The accruals and reserves on the books and records of the Company and the Subsidiaries in respect of tax liabilities for any taxable period not finally determined are adequate to meet any assessments and related liabilities for any such period and, since the date of the most recent audited consolidated financial statements, the Company and the Subsidiaries have not incurred any liability for taxes other than in the ordinary course of its business. There is no tax lien, whether imposed by any U.S., Canadian or other taxing authority, outstanding against the assets, properties or business of the Company or any Subsidiary.

(oo) There are no transfer taxes or other similar fees or charges under Canadian or U.S. federal law or the laws of any state, province or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Company or sale by the Company of the Shares.

(pp) No stamp duty, registration or documentary taxes, duties or similar charges are payable under the federal laws of Canada or the laws of any province in connection with the creation, issuance, sale and delivery to the Underwriters of the Shares or the authorization, execution, delivery and performance of this Agreement or the resale of Shares by an Underwriter to U.S. residents.

(qq) No dispute between the Company and any local, native or indigenous group exists or is threatened or imminent with respect to any of the Company’s properties or exploration activities that could reasonably be expected to have a Material Adverse Effect.

(rr) No labor disturbance by the employees of the Company or any Material Subsidiary exists or, to the best of the Company’s knowledge, is imminent and the Company is not aware of any existing or imminent labor disturbances by the employees of any of its or any Material Subsidiary’s principal suppliers, manufacturers, customers or contractors, which, in either case (individually or in the aggregate), could reasonably be expected to have a Material Adverse Effect.

(ss) There has been no storage, generation, transportation, handling, use, treatment, disposal, discharge, emission, contamination, release or other activity involving any kind of hazardous, toxic or other wastes, pollutants, contaminants, petroleum products or other hazardous or toxic substances, chemicals or materials (“Hazardous Substances”) by, due to, on behalf of, or caused by the Company or any Subsidiary (or, to the Company’s knowledge, any other entity for whose acts or omissions the Company is or may be liable) upon any property now or previously owned, operated, used or leased by the Company or any Subsidiary, or upon any other property, which would be a violation of or give rise to any liability under any applicable law, rule, regulation, order, judgment, decree or permit, common law provision or other legally binding standard relating to pollution or protection of human health and the environment (“Environmental Law”), except for violations and liabilities which, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. There has been no disposal, discharge, emission contamination or other release of any kind at, onto or from any such property or into the environment surrounding any such property of any Hazardous

Substances with respect to which the Company or any Subsidiary has knowledge, except as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. There is no pending or, to the best of the Company’s knowledge, threatened administrative, regulatory or judicial action, claim or notice of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any Subsidiary. No property of the Company or any Subsidiary is subject to any Lien under any Environmental Law. Except as disclosed in the Pricing Prospectuses and the Prospectuses, neither the Company nor any Subsidiary is subject to any order, decree, agreement or other individualized legal requirement related to any Environmental Law, which, in any case (individually or in the aggregate), could reasonably be expected to have a Material Adverse Effect.

(tt) In the ordinary course of its business, the Company periodically reviews the effect of Environmental Laws on the business, operations and properties of the Company and its Subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure or remediation of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, have a Material Adverse Effect.

(uu) None of the Company, any Subsidiary or, to the Company’s knowledge, any of its employees or agents, has at any time during the last five years (i) made any unlawful contribution to any candidate for non-United States office, or failed to disclose fully any such contribution in violation of law, or (ii) made any payment to any federal or state governmental officer or official, or other person charged with similar public or quasi-public duties, other than payments required or permitted by the laws of the United States of any jurisdiction thereof. The operations of the Company and each Subsidiary are and have been conducted at all times in compliance with applicable financial record-keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any Subsidiary with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened. Neither the Company nor any Subsidiary nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any Subsidiary is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of the Offering, or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(vv) Neither the Company nor any Material Subsidiary (i) is in violation of its certificate or articles of incorporation, by-laws, certificate of formation, limited liability company

agreement, partnership agreement or other organizational documents, (ii) is in default under, and no event has occurred which, with notice or lapse of time or both, would constitute a default under or result in the creation or imposition of any Lien upon any property or assets of the Company or any Material Subsidiary pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which it is a party or by which it is bound or to which any of its property or assets is subject, or (iii) is in violation of any statute, law, rule, regulation, ordinance, directive, judgment, decree or order of any judicial, regulatory or other legal or governmental agency or body, Canadian, U.S. or foreign, except in any such case for violations or defaults that could not (individually or in the aggregate) reasonably be expected to have a Material Adverse Effect.

(ww) The Company has complied with the requirements of Rule 433 under the Securities Act with respect to each Issuer Free Writing Prospectus including, without limitation, all prospectus delivery, filing, record retention and legending requirements applicable to any such Issuer Free Writing Prospectus.

(zz) The minute books and corporate records of the Company and its Material Subsidiaries are true and correct in all material respects and contain all minutes of all meetings and all resolutions of the directors (and any committees of such directors) and shareholders of the Company and its Material Subsidiaries as at the date hereof and at the Closing Date will contain the minutes of all meetings and all resolutions of the directors (and any committees of such directors) and shareholders of the Company and its Material Subsidiaries.

(aaa) The Company is, and upon completion of the transactions described herein, will be, a “foreign private issuer” within the meaning of Rule 3b-4 under the Exchange Act.

Any certificate signed by or on behalf of the Company and delivered to the Lead Manager or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company to each Underwriter and Sub-Underwriter as to the matters covered thereby.

2. Purchase, Sale and Delivery of the Shares.

(a) On the basis of the representations, warranties, covenants and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the U.S. purchase price set forth in Annex IV hereto, the number of Firm Shares set forth opposite their respective names on Schedule I hereto together with any additional number of Shares which such Underwriter may become obligated to purchase pursuant to the provisions of Section 9 hereof.

(b) Payment of the purchase price for, and delivery of certificates representing, the Firm Shares shall be made at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP or at such other place as shall be agreed upon by the Lead Manager and the Company, at 5:45 A.M., Vancouver time, on February 27, 2009, or such other time and date as the Lead Manager and the Company may agree upon in writing (such time and date of payment and delivery being herein called the “Closing Date”). Delivery of certificates for the Firm Shares shall be made to the Lead Manager through the facilities of The Depository Trust Company for the respective accounts of the several Underwriters against payment of the purchase price for the Firm Shares by wire transfer in same day funds to or as directed in writing by the Company.

(c) In addition, on the basis of the representations, warranties, covenants and agreements herein contained, but subject to the terms and conditions herein set forth, the Company hereby grants to the Underwriters, acting severally and not jointly, the option to purchase up to 817,500 Additional Shares at the same purchase price per share to be paid by the Underwriters for the Firm Shares and at the same commission per share to be received by the Underwriters as set forth in Section 2(a) above, for the sole purpose of covering over-allotments in the sale of Firm Shares by the Underwriters. This option may be exercised at any time and

from time to time, in whole or in part on one or more occasions, on or before the thirtieth day following the Closing Date, by written notice from the Lead Manager to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised and the date and time, as reasonably determined by the Lead Manager, when the Additional Shares are to be delivered (any such date and time being herein sometimes referred to as the “Additional Closing Date”); provided, however, that no Additional Closing Date shall occur earlier than the Closing Date or earlier than the second full business day after the date on which the option shall have been exercised nor later than the eighth full business day after the date on which the option shall have been exercised.

4. Covenants of the Company. In addition to the other covenants and agreements of the Company contained herein, the Company further covenants and agrees with each of the Underwriters and the Sub-Underwriters that:

(a) The Company will comply with the Shelf Procedures and General Instruction II.L of Form F-10 under the Securities Act. Prior to the later of the last date on which an Additional Closing Date, if any, may occur, and the termination of the Offering of the Shares, the Company will not file any amendment to the Registration Statement or supplement or amendment to the Prospectuses unless the Company has furnished a copy to the Lead Manager and its legal counsel for their review prior to filing and will not file any such proposed amendment or supplement to which the Lead Manager reasonably objects. The Company will cause the Prospectuses, properly completed, and any supplement thereto to be filed, each in a form approved by the Lead Manager with the Canadian Qualifying Authorities in accordance with the Shelf Procedures (in the case of the Canadian Prospectus) and with the Commission pursuant to General Instruction II.L of Form F-10 (in the case of the U.S. Prospectus) within the time period prescribed and will provide evidence satisfactory to the Lead Manager of such timely filings.

(f) The Company has complied and will comply in all material respects with the requirements of Rule 433 with respect to each Issuer Free Writing Prospectus including, without limitation, all prospectus delivery, filing, record retention and legending requirements applicable to each such Issuer Free Writing Prospectus.

(o) The Company shall provide the Lead Manager with a draft of any press release to be issued in connection with the Offering of the Shares, and will provide the Lead Manager and its counsel sufficient time to comment thereon and will accept all reasonable comments of the Lead Manager and its counsel on such press releases.

(p) Each Underwriter, severally and not jointly, covenants and agrees with the Company that such Underwriter will not use or refer to any “free writing prospectus” (as defined in Rule 405 under the Securities Act) without the prior written consent of the Company, except for any Issuer Free Writing Prospectus set forth in Annex IV hereto and any electronic road show previously approved by the Lead Manager. The Company and each Underwriter, severally and not jointly, agrees that any such free writing prospectus, the use of which has been consented to by the Company and the Underwriters, is listed in Annex IV hereto.

The several obligations of the Underwriters to purchase and pay for the Firm Shares and the Additional Shares, as provided herein, shall be subject to the accuracy of the representations and warranties of the Company herein contained, as of the date hereof and as of the Closing Date (for purposes of this Section 6, “Closing Date” shall refer to the Closing Date for the Firm Shares and any Additional Closing Date, if different, for the Additional Shares), to the performance by the Company of all of its obligations hereunder, and to each of the following additional conditions:

7. Indemnification.

(a) The Company shall indemnify and hold harmless each Underwriter and Sub-Underwriter and each person, if any, who controls any Underwriter or Sub-Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under Canadian Securities Laws, the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages

or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Pricing Prospectus or Prospectus, as originally filed or in any supplement thereto or amendment thereof, in the Registration Statement, as originally filed or any amendment thereof, or in any Issuer Free Writing Prospectus, or in any “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or (B) in any other materials or information provided to investors by, or with the approval of, the Company in connection with the Offering, including in any “road show” (as defined in Rule 433 under the Securities Act) for the Offering (“Marketing Materials”), or (ii) the omission or alleged omission to state in any Pricing Prospectus or Prospectus, as originally filed or in any supplement thereto or amendment thereof, in the Registration Statement, as originally filed or any amendment thereof, or in any Issuer Free Writing Prospectus, or in any “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or in any Marketing Materials, a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made (in the case of any prospectus), not misleading; provided, however, that the Company will not be liable in any such case to the extent but only to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter or Sub-Underwriter through the Lead Manager expressly for use therein. The parties agree that such information provided by or on behalf of any Underwriter or Sub-Underwriter through the Lead Manager consists solely of the material referred to in Section 16 hereof. This indemnity agreement will be in addition to any liability which the Company may otherwise have, including but not limited to other liability under this Agreement.

(b) Each Underwriter and Sub-Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each of the officers and directors of the Company, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under Canadian Securities Laws, the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Pricing Prospectus or Prospectus, as originally filed or any amendment thereof or amendment thereto, or in the Registration Statement, as originally filed or any amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter or Sub

Underwriter through the Lead Manager specifically for use therein; provided, however, that in no case shall any Underwriter or Sub-Underwriter be liable or responsible for any amount in excess of the underwriting commission applicable to the Shares to be purchased by such Underwriter or Sub-Underwriter hereunder. The parties agree that such information provided by or on behalf of any Underwriter or Sub-Underwriter through the Lead Manager consists solely of the material referred to in Section 16 hereof.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claims or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have under this Section 7, unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial right and defenses). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate, at its own expense in the defense of such action, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party acting reasonably; provided however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case (including one local counsel in each relevant jurisdiction), but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, (iii) the indemnifying party does not diligently defend the action after assumption of the defense, or (iv) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which indemnity or contribution may be or could have been sought by an indemnified party under this Section 7 or Section 8 hereof (whether or not the indemnified party is an actual or potential party thereto), unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party. If at any time an indemnified party shall have requested in writing an indemnifying party to reimburse the indemnified party for any fees and expenses as contemplated by this Section 7(c), then the indemnifying party agrees that it shall be liable for

any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days' prior written notice of its intention to settle.

8. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company and the Underwriters and Sub-Underwriters shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims, damages, liabilities and expenses suffered by the Company, any contribution received by the Company from persons, other than the Underwriters and Sub-Underwriters, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Canadian Prospectuses and the Registration Statement and each director of the Company) as incurred to which the Company and one or more of the Underwriters or Sub-Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company and the Underwriters and Sub-Underwriters from the Offering or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company and the Underwriters and Sub-Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters and Sub-Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the Offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bears to (y) the underwriting discount or commissions received by the Underwriters and Sub-Underwriters, in each case as set forth in the table on the cover page of the U.S. Prospectus. The relative fault of each of the Company and of the Underwriters and Sub-Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and Sub-Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters and Sub-Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters and Sub-Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any

investigation or proceeding by any judicial, regulatory or other legal or governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 8, (i) no Underwriter or Sub-Underwriter shall be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Shares underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter or Sub-Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person, if any, who controls an Underwriter or Sub-Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter or Sub-Underwriter, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and each officer and director of the Company shall have the same rights to contribution as the Company subject in each case to clauses (i) and (ii) of the immediately preceding sentence. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. The obligations of the Underwriters and Sub-Underwriters to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares to be purchased by each of the Underwriters and Sub-Underwriters hereunder and not joint.

9. Underwriter Default.

(a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Shares or Additional Shares hereunder, and if the Firm Shares or Additional Shares with respect to which such default relates (the “Default Shares”) do not (after giving effect to arrangements, if any, made by the Lead Manager pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Firm Shares or Additional Shares, each non-defaulting Underwriter, acting severally and not jointly, agrees to purchase from the Company that number of Default Shares that bears the same proportion of the total number of Default Shares then being purchased as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto bears to the aggregate number of Firm Shares set forth opposite the names of the non-defaulting Underwriters, subject, however, to such adjustments to eliminate fractional shares as the Lead Manager in its sole discretion shall make.

(b) In the event that the aggregate number of Default Shares exceeds 10% of the number of Firm Shares or Additional Shares, as the case may be, the Lead Manager may in its discretion arrange for itself or for another party or parties (including any non-defaulting Underwriter or Underwriters who so agree) to purchase the Default Shares on the terms contained herein. In the event that within five calendar days after such a default the Lead Manager do not arrange for the purchase of the Default Shares as provided in this Section 9, this

Agreement or, in the case of a default with respect to the Additional Shares, the obligations of the Underwriters to purchase and of the Company to sell the Additional Shares shall thereupon terminate, without liability on the part of the Company with respect thereto (except in each case as provided in Sections 5, 7, 8, 10 and 11(d)) or the non-defaulting Underwriters, but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder.

(c) In the event that any Default Shares are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, the Lead Manager or the Company shall have the right to postpone the Closing Date or Additional Closing Date, as the case may be for a period, not exceeding five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectuses or in any other documents and arrangements, and the Company agrees to file promptly any amendment or supplement to the Registration Statement or the Prospectuses which, in the opinion of Underwriters’ Counsel, may thereby be made necessary or advisable. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 9 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and Additional Shares.

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Underwriters, the Sub-Underwriters and the Company contained in this Agreement or in certificates of officers of the Company or any Subsidiary submitted pursuant hereto, including the agreements contained in Section 5, the indemnity agreements contained in Section 7 and the contribution agreements contained in Section 8, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter, Sub-Underwriter or any controlling person thereof or by or on behalf of the Company, any of its officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Shares to and by the Underwriters. The representations contained in Section 1 and the agreements contained in Sections 5, 7, 8, 10 and 11 hereof shall survive any termination of this Agreement, including termination pursuant to Section 9 or 11 hereof.

11. Effective Date of Agreement; Termination.

(a) This Agreement shall become effective when the parties hereto have executed and delivered this Agreement.

(b) The Underwriters shall have the right to terminate this Agreement at any time prior to the Closing Date or to terminate the obligations of the Underwriters to purchase the Additional Shares at any time prior to the Additional Closing Date, as the case may be, if, at or after the Applicable Time, (i) any domestic or international event or act or occurrence has materially disrupted, or in the opinion of the Underwriters will in the immediate future materially disrupt, the market for the Company’s securities or securities in general; or (ii) trading in the Company’s common shares shall have been suspended by the Commission, the Canadian Qualifying Authorities, the TSX or Nasdaq, or trading in securities generally on the New York

Stock Exchange (“NYSE”), Nasdaq or on the TSX shall have been suspended or been made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE, Nasdaq or TSX or by order of the Commission or any other governmental authority having jurisdiction; or (iii) a banking moratorium has been declared by any U.S. state or U.S. or Canadian federal authority or any material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (iv) any downgrading shall have occurred in the Company’s corporate credit rating or the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Securities Act) or any such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities or any notice or announcement shall have been given or made of any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded; or (v) (A) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States or (B) there shall have been any other calamity or crisis or any change in political, financial or economic conditions if the effect of any such event in (A) or (B), in the judgment of the Underwriters, makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Shares or the Additional Shares, as the case may be, on the terms and in the manner contemplated by the Prospectuses.

(d) If this Agreement shall be terminated pursuant to any of the provisions hereof (other than pursuant to Section 9(b) hereof), or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters or the Sub-Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Underwriters, reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and expenses of their counsel), incurred by the Underwriters in connection herewith.

14. Governing Law and Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by and construed in accordance with the laws of the State of New York. The Company irrevocably (a) submits to the jurisdiction of any court of the State of New York or the United States District Court for the Southern District of the State of New York (each a “New York Court”) for the purpose of any suit, action, or other proceeding arising out of this Agreement, or any of the agreements or transactions contemplated by this Agreement, the Registration Statement and the Prospectuses (each, a “Proceeding”), (b) agrees that all claims in respect of any Proceeding may be heard and determined in any New York Court, (c) waives, to the fullest extent permitted by law, any immunity from jurisdiction of any New York Court or from any legal process therein, (d) agrees not to commence any Proceeding other than in a New York Court, and (e) waives, to the fullest extent permitted by law, any claim that such Proceeding is brought in an inconvenient forum. The Company hereby irrevocably designates CT Corporation System, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, as agent upon whom process against the Company may be served. THE COMPANY (ON BEHALF OF ITSELF AND, TO THE FULLEST EXTENT PERMITTED BY LAW, ON BEHALF OF ITS RESPECTIVE EQUITY HOLDERS AND CREDITORS) HEREBY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED UPON, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, THE REGISTRATION STATEMENT AND THE PROSPECTUS.

15. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase U.S. dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligations of the Company in respect of any sum due from it to any Underwriter shall, notwithstanding any judgment in any currency

other than U.S. dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Underwriter hereunder.

16. The parties acknowledge and agree that, for purposes of Sections 1(c), 1(d), 1(e), 1(f) and 7 hereof, the information provided by or on behalf of any Underwriter or Sub-Underwriter consists solely of the material included in paragraphs 6, 12, 13, and 14 in each case under the caption “Underwriting” in the Prospectuses, only insofar as such statements relate to selling concession and stabilization activities that may undertaken by any Underwriter or Sub-Underwriter.

17. No Fiduciary Relationship. The Company hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Company’s securities contemplated hereby. The Company further acknowledges that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Company, its management, shareholders or creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of such purchase and sale of the Company’s securities, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company and the Underwriters agree that the Underwriters are acting as principal and not the agent or fiduciary of the Company and no Underwriter has assumed, and no Underwriter will assume, any advisory responsibility in favor of the Company with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether any Underwriter has advised or is currently advising the Company on other matters). The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of any fiduciary, advisory or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

18. Miscellaneous. UBS, an indirect, wholly owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS

AG. Because UBS is a separately incorporated entity, it is solely responsible for its own contractual obligations and commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by UBS are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

19. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument. Delivery of a signed counterpart of this Agreement by facsimile transmission shall constitute valid and sufficient delivery thereof.

20. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

21. Time is of the Essence. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

If the foregoing correctly sets forth your understanding, please so indicate in the space provided below for that purpose, whereupon this letter shall constitute a binding agreement among us.

1. Joint venture agreement, dated September 6, 2005, between ▇▇▇▇▇▇▇▇▇ Silver Corporation and the Company.

ANNEX I

Form of Opinion of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP

Each of the Company and Silver Standard Ventures Inc. and 777666 B.C. Ltd. (the “Canadian Subsidiaries”) has been duly incorporated and validly exists as a corporation in good standing with respect to the filing of returns under the laws of its jurisdiction of incorporation, with all necessary corporate power and capacity to own, lease or license, as the case may be, its properties and conduct its business as described in the Prospectuses. The Company and the Canadian Subsidiaries are extra-provincially registered in [Provinces to be specified].

The Company has an authorized capitalization as set forth in the Prospectuses. The share capital of the Company conforms in all material respects to the description thereof contained under the heading “Description of Share Capital” in the Prospectuses. The Shares to be delivered on the Closing Date and the Additional Closing Date, if any, have been duly and validly authorized and, when delivered in accordance with the Underwriting Agreement, will be duly and validly issued, fully paid and non-assessable. The holders of the outstanding common shares of the Company are not entitled to subscribe for the Shares pursuant to preemptive or similar rights under the Company’s constating documents or the Material Agreements. All of the issued shares in the share capital of the Canadian Subsidiaries as reflected in the securities registers of the Canadian Subsidiaries are registered in the name of the Company. The form of certificates for the common shares of the Company complies with British Columbia statutory requirements, with any applicable requirements of the constating documents of the Company and with the requirements of the TSX.

3.	To the knowledge of such counsel, no holders of securities of the Company have rights to the qualification of such securities under the Canadian Prospectus.

4.	The outstanding common shares of the Company are listed on the TSX and the Shares have been conditionally approved for listing on the TSX.

5.	The Underwriting Agreement has been duly and validly authorized, executed and delivered by the Company (to the extent that execution and delivery are governed by the laws of British Columbia).

To such counsel’s knowledge and other than as set forth in the Pricing Prospectuses and the Prospectuses, there are no judicial, regulatory or other legal or governmental proceedings pending by or before any court or governmental agency, authority or body to which the Company or any of its Subsidiaries is a party or of which any property of the Company or any of its Subsidiaries is the subject which, if determined adversely to the Company or any of its Subsidiaries, would individually or in the aggregate have a Material Adverse Effect; and, to such counsel’s knowledge, no such proceedings are threatened.

The execution, delivery, and performance of the Underwriting Agreement and consummation of the transactions contemplated by the Underwriting Agreement and the Prospectuses do not and will not (A) conflict with or result in a breach of any of the terms and provisions of, or constitute a default (or an event which with notice or lapse of time, or both, would constitute a default) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its Subsidiaries pursuant to the Material Agreements, or (B) violate or conflict with any provision of the constating documents of the Company or the Canadian Subsidiary, or, to the knowledge of such counsel, any judgment, decree, order, statute, rule or regulation of any Canadian court or judicial, regulatory or other legal or governmental agency or body.

8.	The Company is a “reporting issuer” under the securities legislation of each of the Canadian Jurisdictions which provide for such status and is not on the list of defaulting issuers maintained thereunder.

The statements under the captions “Eligibility for Investment”, “Certain Income Tax Considerations for U.S. Holders – Certain Canadian Federal Income Tax Considerations”, “Certain Income Tax Considerations for Canadian Holders” and “Statutory Rights of Withdrawal and Rescission” in the Canadian Prospectus and Part II - Indemnification of the Registration Statement, insofar as such statements constitute a summary of the legal matters, documents or proceedings referred to therein, are, in all material respects, accurate summaries of such legal matters, documents and proceedings.

10.

A Decision Document has been obtained in respect of the Canadian Preliminary Base Shelf Prospectus and the Canadian Final Base Shelf Prospectus from the Reviewing Authority and, subject to the filing of standard post-closing notices of distribution, all necessary documents have been filed, all necessary proceedings have been taken and all necessary consents, approvals, and authorizations have been obtained, in each case by the Company, under Canadian Securities Laws to permit the Shares to be offered, sold and delivered, as contemplated by the Underwriting Agreement in the Canadian Jurisdictions by or through investment dealers or brokers duly and properly registered under Canadian Securities Laws who have complied with the relevant provisions of such laws and the terms of such registration; to the knowledge of such counsel, no order suspending the distribution of the Shares has been issued, no proceedings for that purpose have been instituted or threatened by any of the Canadian Qualifying Authorities.

11.	If the Underwriting Agreement is sought to be enforced in the Province of British Columbia in the first instance, in a court of competent jurisdiction (a “B.C. Court”):

(a)

a B.C. Court will only take jurisdiction over such an action if it concludes it has territorial competence to do so pursuant to section 3 of the Court Jurisdiction and Proceedings Transfer Act, S.B.C. 2003, c. 28, or if it has a basis for exercising its residual discretion to take jurisdiction pursuant to section 6 of that Act;

(b)	a B.C. Court, despite concluding that it has territorial competence, retains the discretion to decline to take jurisdiction on the following grounds:

(i)	to do so would be contrary to public policy, as that term is understood under the laws of the Province of British Columbia and the laws of Canada applicable therein (“Public Policy”);

(ii)	the B.C. Court concludes that it should decline to exercise its territorial competence to hear such an action pursuant to section 11 of the Court Jurisdiction and Proceedings Transfer Act on the ground that a court of another state is a more appropriate forum in which to hear the action;

(iii)

the B.C. Court concludes that by way of a clause in the Underwriting Agreement (the “Forum Selection Clause”), the parties have selected the courts of the State of New York as the exclusive jurisdiction for the resolution of any disputes arising out of or relating to the Underwriting Agreement, the action in question falls within the Forum Selection Clause and that there is no strong cause not to give effect to the Forum Selection Clause. A B.C. Court may conclude there is strong cause not to enforce the Forum Selection Clause where: A) it offends Public Policy; B) it was the product of grossly uneven bargaining positions; C) it is otherwise unconscionable; or D) the agreement in which the clause is found is void.

(c)

a B.C. Court would give effect to the choice of the law of the State of New York (“New York law”) as the governing law of contract claims under the Underwriting Agreement, provided that such choice of law is bona fide (in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction), provided that such choice of law is not contrary to Public Policy, and provided that such choice of law is not in conflict with a mandatory system of laws that would otherwise be the proper law of the Underwriting Agreement. We have no reason to believe that the choice of New York law to govern the Underwriting Agreement (except as to provisions in the Underwriting Agreement relating to indemnity or contribution, as to which we need express no opinion) is not bona fide, would be contrary to Public Policy, or would conflict with a mandatory system of laws that would otherwise be the proper law of the Underwriting Agreement;

(d)

a B.C. Court would, if it took jurisdiction over the action, subject to paragraph (c) above, recognize the choice of New York law and, upon appropriate evidence as to such law being adduced, apply such law with respect to those matters which under the laws of the Province of British Columbia are to be determined by the proper law of the Underwriting Agreement (and in particular, but without limitation, not with respect to matters of procedure), provided that none of the provisions of Underwriting Agreement, or of applicable New York law, is contrary to Public Policy and that those laws are not foreign revenue, expropriatory or penal laws or other laws of a public nature; provided, however, that, in matters of procedure, the laws of the Province of British Columbia will be applied, and a B.C. Court may not enforce an obligation enforceable under New

York law where performance of the obligation would be illegal by the law of the place of performance.

12.

The laws of the Province of British Columbia and the laws of Canada applicable therein permit an action to be brought in a B.C. Court on a final and conclusive judgment in personam of a New York Court that is subsisting and unsatisfied respecting the enforcement of the Underwriting Agreement that is not impeachable as void or voidable under New York law for a sum certain if: (A) the New York Court rendering such judgment had jurisdiction, as determined under British Columbia Law, over the judgment debtor and the subject matter of the action. In this context, the B.C. Court would give effect to the appointment by the Company of CT Corporation as its agent to receive service of process in the United States of America and to the provisions of Underwriting Agreement whereby the Company submits to the jurisdiction of a New York Court; (B) such judgment was not obtained by fraud or in a manner contrary to natural justice and the enforcement thereof would not be inconsistent with Public Policy or contrary to any order made by the Attorney-General of Canada under the Foreign Extraterritorial Measures Act (Canada) or any order made by the Competition Tribunal under the Competition Act (Canada); (C) the enforcement of such judgment does not constitute, directly or indirectly, the enforcement of foreign revenue, expropriatory or penal laws or other laws of a public nature; (D) the action to enforce such judgment is commenced within the applicable limitation period; (E) in the case of a judgment obtained by default, there has been no manifest error in the granting of such judgment; and (F) no new admissible evidence, right or defence relevant to the action is discovered prior to the rendering of judgment by a B.C. Court. Under the Currency Act (Canada), a B.C. Court may only give judgment in Canadian dollars. However, pursuant to the Foreign Money Claims Act, R.S.B.C. 1996, c. 155, a B.C. court must order that the money payable under an order will be that amount of Canadian currency that is necessary to purchase the equivalent amount of a foreign currency at a chartered bank located in British Columbia at the close of business on the conversion date, if the court considers that the person in whose favour the order will be made will be most truly and exactly compensated if all or part of the money payable under the order is measured in a currency other than the currency of Canada. The conversion date under the Foreign Money Claims Act is the last day, before the day on which a payment under the order is made by the judgment debtor to the judgment creditor that said chartered bank quotes a Canadian dollar equivalent to the other currency.

13.

No stamp or other issuance or transfer taxes or duties or withholding taxes are payable by or on behalf of the Underwriters to the Government of Canada or the Government of British Columbia or any political subdivision thereof or any authority or agency thereof or therein having power to tax in connection with (A) the issue, sale and delivery of the Shares by the Company to or for the respective accounts of the Underwriters or (B) the sale and delivery outside Canada by the Underwriters of the Shares in the manner contemplated in the Underwriting Agreement.

In addition, such counsel shall also state in a separate letter:

“The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many determinations involved in the preparation of the Canadian Prospectus and the documents incorporated by reference therein are of a wholly or partially non-legal character or relate to legal matters outside the scope of the Opinion. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Canadian Prospectus (other than as explicitly stated in paragraph 9 of the Opinion).

In the course of acting as Canadian counsel to the Company in connection with the offering of the Shares, we have participated in conferences and telephone conversations with officers and other representatives of the Company, its U.S. counsel, your representatives and your legal counsel and the independent registered public accountants for the Company during which conferences and conversations the contents of the Canadian Pricing Prospectus and the Canadian Prospectus and related matters were discussed. Based upon such participation (and relying as to materiality with respect to factual matters to the extent we deemed reasonable on officers, employees and other representatives of the Company), we hereby advise you that our work in connection with this matter did not disclose any information that gave us reason to believe that (i) as of the Applicable Time, the Pricing Disclosure Package (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference and the information derived from the reports of, or prepared under the supervision of or reviewed by (as stated therein), Mine Development Associates, Inc., ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇, CPG, ▇▇▇▇▇▇▇ Mining Industry Consultants Inc., ▇▇▇▇ ▇. ▇▇▇▇▇, ▇.▇▇., P.

For purposes of this letter, the term “Pricing Disclosure Package” means the Canadian Pricing Prospectus taken together with the information set forth in Annex IV to the Underwriting Agreement, to the extent determined at the Applicable Time.”

ANNEX II

Form of Opinion of ▇▇▇▇, Weiss, Rifkind, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP

Mina Pirquitas, Inc. has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware and has all necessary corporate power and authority to own and hold its properties and conduct its business as described in the Registration Statement and the U.S. Prospectus.

2.	All of the issued shares of capital stock of Mina Pirquitas, Inc. are owned of record directly or indirectly by the Company.

3.	To such counsel’s knowledge, there are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by the Underwriting Agreement.

Assuming the due authorization, execution and delivery of the Underwriting Agreement under the laws of the Province of British Columbia and the federal laws of Canada applicable therein, the Underwriting Agreement (to the extent that execution and delivery are governed by the laws of the State of New York) has been duly authorized, executed and delivered by the Company.

5.	To such counsel’s knowledge, there are no legal proceedings pending or overtly threatened against the Company or any of its subsidiaries which could reasonably be expected to have a material adverse effect on the Company and its subsidiaries, taken as a whole.

The issuance and sale of the Shares by the Company, the compliance by the Company with all of the provisions of the Underwriting Agreement and the performance by the Company of its obligations thereunder will not violate Applicable Law or any judgment, order or decree of any court or arbitrator known to such counsel. For purposes of this letter, the term “Applicable Law” means the General Corporation Law of the State of Delaware and those laws, rules and regulations of the United States of America and the State of New York, in each case which in such counsel’s experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement, except that, “Applicable Law” does not include the anti-fraud provisions of the securities laws of any applicable jurisdiction or any state securities or Blue Sky laws of the various states.

No consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made is required by the Company under any Applicable Law for the issuance or sale of the Shares or the performance by the Company of its obligations under the Underwriting Agreement. For purposes of this letter, the term “Governmental Authority” means any

executive, legislative, judicial, administrative or regulatory body of the State of New York, the State of Delaware or the United States of America.

The Registration Statement and the U.S. Prospectus, as of their respective effective or issue times, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission under the Act (the “Rules and Regulations”), except for the financial statements, financial statement schedules and other financial data included or incorporated by reference in or omitted from either of them, as to which such counsel expresses no opinion.

The Company’s Annual Report on Form 20-F for the fiscal year ended December 31, 2007, as amended, which is incorporated by reference in the Registration Statement and U.S. Prospectus (except for financial statements, financial statement schedules and other financial data included or incorporated by reference, in or omitted from either of them, as to which such counsel expresses no opinion) appeared on its face to be appropriately responsive in all material respects when so filed to the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations thereunder.

10.	The Form F-X appears on its face to be appropriately responsive in all material respects to the requirements of the Act and the Rules and Regulations.

11.

The statements in the U.S. Prospectus under the headings “Certain income tax considerations for U.S. holders—Certain U.S. Federal Income Tax Considerations” and “Underwriting” to the extent that they constitute summaries of United States federal law or regulation or legal conclusions or documents, have been reviewed by such counsel and fairly summarize the matters described under that heading in all material respects.

12.

The Company is not and, after giving effect to the offering and sale of the Shares, and the application of their proceeds as described in the U.S. Prospectus under the heading “Use of proceeds,” will not be required to be registered as an investment company under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission promulgated thereunder.

Under the laws of the State of New York relating to submission to jurisdiction, the Corporation has, pursuant to Section 14 of the Underwriting Agreement, validly and irrevocably submitted to the personal jurisdiction of any state or federal court located in the State of New York, in any action arising out of or relating to the Underwriting Agreement or the transactions contemplated thereby, has validly and irrevocably waived any objection to the venue of a proceeding in any state court located in the State of New York, and has validly and irrevocably appointed CT Corporation System as its authorized agent for the purpose described in the Underwriting Agreement. This opinion 13 is subject to the qualification that such counsel expresses no opinion as to the enforceability of forum selection clauses in the federal courts.

In addition, such counsel shall also state in a separate letter:

“The Company has filed with the Commission a Registration Statement on Form F-10 (File No. 333-157223) under the Securities Act. The Registration Statement was filed on February 11, 2009 and was amended on February 19, 2009. The Registration Statement became effective pursuant to Rule 467(b) under the Securities Act on February 23, 2009. All filings required by Item II.L. of Form F-10 under the Securities Act have been made in the manner and in the time period required therein. The Form F-X of the Company dated February 10, 2009 (the “Form F-X”) was filed with the Commission prior to the effectiveness of the Registration Statement.

We have been advised orally by the staff of the Commission that no stop order suspending the effectiveness of the Registration Statement has been issued and to our knowledge no proceedings for that purpose have been initiated or are pending or are threatened by the Commission.

The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many determinations involved in the preparation of the Registration Statement, U.S. Pricing Prospectus and the U.S. Prospectus and the documents incorporated by reference therein are of a wholly or partially non-legal character or relate to legal matters outside the scope of the Opinion. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the U.S. Pricing Prospectus or the U.S. Prospectus or the documents incorporated by reference therein (other than as explicitly stated in paragraph 11 of the Opinion).

In the course of acting as special U.S. counsel to the Company in connection with the offering of the Shares, we have participated in conferences and telephone conversations with officers and other representatives of the Company, its Canadian counsel, your representatives and your legal counsel and the independent registered public accountants for the Company during which conferences and conversations the contents of the Registration Statement, the U.S. Pricing Prospectus, the U.S. Prospectus and related matters were discussed. Based upon such participation (and relying as to materiality with respect to factual matters to the extent we deemed reasonable on officers, employees and other representatives of the Company), we hereby advise you that our work in connection with this matter did not disclose any information that gave us reason to believe that (i) at the time it became effective, the Registration Statement or any amendment thereto prior to the Closing Date (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference, and the information derived from the reports of, or prepared under the supervision of or reviewed by (as stated therein) Mine Development Associates, Inc., ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇, CPG, ▇▇▇▇▇▇▇ Mining Industry Consultants Inc., ▇▇▇▇ ▇. ▇▇▇▇▇, ▇.▇▇., P.

c/o UBS Securities Canada Inc.

Silver Standard Resources Inc. Lock-Up Agreement

Ladies and Gentlemen:

This letter agreement (this “Agreement”) relates to the proposed public offering (the “Offering”) by Silver Standard Resources Inc., a British Columbia corporation (the “Company”), of its common shares, without par value (the “Shares”).

In order to induce you and the other underwriters for which you act as representatives (the “Underwriters”) to underwrite the Offering, the undersigned hereby agrees that, without the prior written consent of UBS Securities Canada Inc. (the “Lead Manager”), during the period from the date hereof until ninety (90) days from the date of the final prospectus for the Offering (the “Lock-Up Period”), the undersigned (a) will not, directly or indirectly, offer, sell, agree to offer or sell, solicit offers to purchase, grant any call option or purchase any put option with respect to, pledge, borrow or otherwise dispose of any Relevant Security (as defined below), and (b) will not establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” with respect to any Relevant Security (in each case within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder), or otherwise enter into any swap, derivative or other transaction or arrangement that transfers to another, in whole or in part, any economic consequence of ownership of a Relevant Security, whether or not such transaction is to be settled by delivery of Relevant Securities, other securities, cash or other consideration. As used herein “Relevant Security” means the Shares, any other equity security of the Company or any of its subsidiaries and any security convertible into, or exercisable or exchangeable for, any Shares or other such equity security. Notwithstanding the foregoing, (i) the undersigned may transfer Relevant Securities by bona fide gift, will or intestate succession, and (ii) the undersigned may transfer Relevant Securities to any corporate entity or partnership controlled by the undersigned, provided as to (i) and (ii) above, each resulting transferee of Relevant Securities executes and delivers to you an agreement satisfactory to you certifying that such transferee is bound by the terms of this Agreement and has been in compliance with the terms hereof since the date first above written as if it had been an original party hereto.

This Agreement shall not apply to the exercise of an option to purchase any shares of the Company’s capital stock pursuant to existing stock option plans of the Company. In addition, this Agreement shall not restrict the sale or other disposition of Relevant Securities

that are acquired by the undersigned in the open market after the Offering is priced, provided that any such sale or other disposition fully complies with, and is not required to be disclosed or reported under, applicable law (including but not limited to Section 16 under the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder).

The undersigned hereby authorizes the Company during the Lock-Up Period to cause any transfer agent for the Relevant Securities to decline to transfer, and to note stop transfer restrictions on the share register and other records relating to, Relevant Securities for which the undersigned is the record holder and, in the case of Relevant Securities for which the undersigned is the beneficial but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to transfer, and to note stop transfer restrictions on the share register and other records relating to, such Relevant Securities. The undersigned hereby further agrees that, without the prior written consent of the Lead Manager, during the Lock-up Period the undersigned (x) will not file or participate in the filing with the Securities and Exchange Commission of any registration statement, or circulate or participate in the circulation of any preliminary or final prospectus or other disclosure document with respect to any proposed offering or sale of a Relevant Security and (y) will not exercise any rights the undersigned may have to require registration with the Securities and Exchange Commission of any proposed offering or sale of a Relevant Security.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that this Agreement constitutes the legal, valid and binding obligation of the undersigned, enforceable in accordance with its terms. Upon request, the undersigned will execute any additional documents necessary in connection with enforcement hereof. Any obligations of the undersigned shall be binding upon the successors and assigns of the undersigned from the date first above written.

This Agreement shall terminate and be of no further force and effect in the event the Company has not consummated the Offering by March 31, 2009.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York. Delivery of a signed copy of this letter by facsimile transmission shall be effective as delivery of the original hereof.
