THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”) OR ANY STATE SECURITIES LAWS, AND MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY (A) TO THE COMPANY, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH REGULATION S UNDER THE U.S. SECURITIES ACT, (D) IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS, OR (E) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE LAWS AND REGULATIONS GOVERNING THE OFFER AND SALE OF SECURITIES, AND, IN THE CASE OF (C), (D) OR (E), THE HOLDER HAS PRIOR TO SUCH TRANSFER FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE SATISFACTORY TO THE CORPORATION.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, SUCH SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON THE TSX.

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [insert date that is 4 months and a day after issuance].

Except for the specific representations and warranties expressly made by the Company in Section 2.1 of this Agreement, Buyers acknowledge that (a) neither the Company, its Affiliates nor any other Person has made any representation or warranty, express or implied, as to the Company, the Company’s business, assets, liabilities, operations, prospects, condition (financial or otherwise), including with respect to the effectiveness or success of the Company’s exploration activities or future capital raising activities, and (b) no officer, agent, representative or employee of the Company has any authority, express or implied, to make any representations, warranties or agreements not specifically set forth in this Agreement. Each Buyer specifically disclaims that it is relying upon or has relied upon any representations or warranties that may have been made by any Person except for the specific representations and warranties expressly made by the Company in Section 2.1.

The Company shall use its commercially reasonable efforts to promptly respond to comments from the SEC regarding the Initial Resale Registration Statement, to cause the Initial Resale Registration Statement to be declared effective under the Securities Act no later than September 30, 2010 (the “Effectiveness Deadline Date”), and to keep the Initial Resale Registration Statement (or any Subsequent Resale Registration Statement) continuously effective under the Securities Act until the expiration of the Effectiveness Period.

If the Initial Resale Registration Statement or any Subsequent Resale Registration Statement ceases to be effective for any reason at any time during the Effectiveness Period, the Company shall use its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within thirty (30) days of such cessation of effectiveness amend the Resale Registration Statement in a manner reasonably expected by the Company to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Resale Registration Statement covering all of the securities that as of the date of such filing are Registrable Securities (a “Subsequent Resale Registration Statement”). If a Subsequent Resale Registration Statement is filed, the Company shall use commercially reasonable efforts to cause the Subsequent Resale Registration Statement to become effective as promptly as is reasonably practicable after such filing or, if filed during a Deferral

Period, after the expiration of such Deferral Period, and to keep such Registration Statement (or Subsequent Resale Registration Statement) continuously effective until the end of the Effectiveness Period.

The Company shall supplement and amend the Initial or any Subsequent Resale Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Resale Registration Statement, if required by the Securities Act.

Each Holder of Registrable Securities agrees that if such Holder wishes to sell Registrable Securities pursuant to a Resale Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(d), Section 3(d) and Section 4. Each Holder of Registrable Securities wishing to sell Registrable Securities pursuant to any Resale Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company promptly upon becoming a Holder and notify the Company of any change in such information at least five (5) business days prior to the filing of the Initial Resale Registration Statement or Subsequent Resale Registration Statement, as applicable. From and after the date the Initial Resale Registration Statement is declared effective, the Company shall, as promptly as is reasonably practicable after the date a fully completed and legible Notice and Questionnaire is received by the Company, (i) if required by applicable law, file with the SEC a post-effective amendment to the Resale Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other document required by the SEC so that the Holder delivering such Notice and Questionnaire is named as a selling security holder in the Resale Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Registrable Securities in accordance with applicable law (other than laws not generally applicable to all Holders of Registrable Securities wishing to sell Registrable Securities pursuant to the Resale Registration Statement and related Prospectus) and using the manner of sale specified in the Notice and Questionnaire, and, if the Company shall file a post-effective amendment to the Resale Registration Statement, use commercially reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is reasonably practicable; (ii) provide such Holder copies of any documents filed pursuant to Section 2(d)(i); and (iii) notify such Holder as promptly as is reasonably practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2(d)(i); provided, that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with Section 3(d), provided, further, that if under applicable law the Company has more than one option as to the type or manner of making any such filing, the Company will make the required filing or filings in the manner or of a type that is reasonably expected to result in the earliest availability of the Prospectus for effecting resales of

Registrable Securities. Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling security holder in any Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder pursuant to the provisions of this Section 2(d) of this Agreement (whether or not such Holder was a Notice Holder at the time the Registration Statement was initially declared effective) shall be named as a selling security holder in the Registration Statement or related Prospectus subject to and in accordance with the requirements of this Section 2(d).

If a Registration Statement covering all the Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is (A) not filed with the SEC on or before the Filing Deadline Date (a “Filing Failure”) or (B) not declared effective by the SEC on or before the Effectiveness Deadline Date (an “Effectiveness Failure”), then, as liquidated damages to Buyers by reason of any such delay in or reduction of its ability to sell the Shares (which remedy shall be the exclusive remedy for any Filing Failure or Effectiveness Failure (each, a “Failure”)), the Company shall pay to Buyers an amount equal to 1.0% of the aggregate purchase price paid by Buyers for the Shares for every thirty (30) days following the Filing Deadline Date that the Registration Statement is not filed (in the case of a Filing Failure) and for every thirty (30) days following the Effectiveness Deadline Date that the Registration Statement is not effective (in the case of an Effectiveness Failure), as the case may be, on a per diem basis (the “Liquidated Damages”); provided, however, that the maximum Liquidated Damages payable to Buyers under this Section 2(e) shall not exceed 3.0% of the aggregate purchase price of the Shares. Liquidated Damages, if any, shall be paid by the Company within ten (10) days following the end of each thirty (30) day period (or shorter period, if applicable) for which Liquidated Damages are payable. The Company shall pay interest on Liquidated Damages not paid when due at a rate of interest equal to fifteen percent (15.0%) per annum. In the event a Registration Statement is filed but is withdrawn by the Company prior to being declared effective by the SEC, then such Registration Statement will be deemed to have not been filed for the purpose of this Section 2(e).

Registration Procedures.

In connection with the registration obligations of the Company under Section 2 hereof, the Company shall:

Prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable period specified in Section 2(a); cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and use commercially reasonable efforts to comply with the provisions of the Securities Act applicable to it with respect to the disposition of all securities covered by such Registration

Statement during the Effectiveness Period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement as so amended or such Prospectus as so supplemented.

Submit to the SEC, within two (2) Business Days after the Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff has no further comments on a particular Registration Statement, as the case may be, a request for acceleration of effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request.

Use commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in either case at the earliest possible moment or, if any such order or suspension is made effective during any Deferral Period, at the earliest possible moment after the expiration of such Deferral Period.

Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of the Resale Registration Statement or the initiation of proceedings with respect to the Resale Registration Statement under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any fact (a “Material Event”) as a result of which any Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (including, in any such case, as a result of the non-availability of financial statements), or (C) the occurrence or existence of any development, event, fact, situation or circumstance relating to the Company that, in the discretion of the Company, makes it appropriate to suspend the availability of the Resale Registration Statement and the related Prospectus, (i) in the case of clause (B) above, subject to the next sentence, as promptly as is reasonably practicable prepare and file a post-effective amendment to such Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference or file any other required document that would be incorporated by reference into such Registration Statement and Prospectus so that such Registration Statement does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and such Prospectus does not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, and, in the case of a post-effective amendment to a Registration Statement, subject to the next sentence, use commercially reasonable efforts to cause it to be

declared effective as promptly as is reasonably practicable, and (ii) give notice (via facsimile, telephone or electronic mail followed by a written notice by internationally recognized overnight courier) to the Notice Holders that the availability of the Resale Registration Statement is suspended (a “Deferral Notice”) and, upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to the Registration Statement until such Notice Holder’s receipt of copies of the supplemented or amended Prospectus provided for in clause (i) above, or until it is advised in writing by the Company that the Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. The Company will use commercially reasonable efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as is reasonably practicable, (y) in the case of clause (B) above, as soon as, in the sole reasonable judgment of the Company, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid unreasonable burden or expense, as soon as reasonably practicable thereafter and (z) in the case of clause (C) above, as soon as, in the reasonable discretion of the Company, such suspension is no longer appropriate. The period during which the availability of the Registration Statement and any Prospectus is suspended (the “Deferral Period”) is not to exceed (i) 20 consecutive days at any one time; (ii) 30 days in the aggregate in any three-month period; or (iii) 60 days in the aggregate during any 12-month period, or as otherwise required by applicable regulatory authority; provided that, the number of days the Company is required to keep the Registration Statement effective shall be extended by the number of days equal to the aggregate Deferral Period(s). The first day of any Deferral Period must be at least two (2) trading days after the last day of any prior Deferral Period.

During the Effectiveness Period (except during such periods that a Deferral Notice is outstanding and has not been revoked), deliver to each Notice Holder in connection with any sale of Registrable Securities pursuant to a Registration Statement, without charge, as many copies of the Prospectus or Prospectuses relating to such Registrable Securities and any amendment or supplement thereto as such Notice Holder may reasonably request; and the Company hereby consents (except during such periods that a Deferral Notice is outstanding and has not been revoked) to the use of such Prospectus or each amendment or supplement thereto by each Notice Holder in connection with any offering and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto in the manner set forth therein.

Subject to Section 3(d), prior to any public offering of the Registrable Securities pursuant to the Resale Registration Statement, use commercially reasonable efforts to register or qualify or cooperate with the Notice Holders in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Notice Holder reasonably requests in writing (which request may be included in the Notice and

Questionnaire), it being agreed that no such registration or qualification will be made unless so requested; prior to any public offering of the Registrable Securities pursuant to the Resale Registration Statement, use commercially reasonable efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period in connection with such Notice Holder’s offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption therefrom) and do any and all other acts or things necessary to enable the disposition in such jurisdictions of such Registrable Securities in the manner set forth in the relevant Registration Statement and the related Prospectus; provided, that the Company will not be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it is not otherwise qualified or (ii) take any action that would subject it to general service of process in suits or to taxation in any such jurisdiction where it is not then so subject.

Holder’s Obligations.

Each Holder agrees, by acquisition of the Registrable Securities, that no Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a properly completed Notice and Questionnaire as required pursuant to this Section 4 (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Holder agrees to deliver a Notice and Questionnaire to the Company promptly upon becoming a Holder and notify the Company of any change in such information at least five (5) business days prior to the filing of the Initial Resale Registration Statement or Subsequent Resale Registration Statement, as applicable. Each Notice Holder agrees promptly to furnish to the Company in writing all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading, any other information regarding such Notice Holder and the distribution of such Registrable Securities as may be required to be disclosed in the Registration Statement under applicable law or pursuant to SEC comments and any information otherwise required by the Company to comply with applicable law or regulations. Each Holder further agrees, following termination of the Effectiveness Period, to notify the Company, within ten (10) Business Days of a request, of the amount of Registrable Securities sold pursuant to the Registration Statement and, in the absence of a response, the Company may assume that all of the Holder’s Registrable Securities were so sold.

Registration Expenses.

The Company shall bear all fees and expenses incurred in connection with the performance by the Company of its obligations under Sections 2 and 3 of this Agreement whether or not any of the Registration Statements are declared effective. Such fees and expenses shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (x) with respect to filings required to be made with the Toronto Stock Exchange and the NYSE Amex (or such U.S. national securities exchange on which the Common Stock is then listed) and (y) of compliance with U.S. federal and state securities or “Blue Sky” laws to the extent such filings or compliance are required pursuant to this Agreement (including, without limitation,

The Company covenants that, if at any time before the end of the Effectiveness Period the Company is not subject to the reporting requirements of the Exchange Act, it will cooperate with any Holder of Registrable Securities and take such further reasonable action as any Holder of Registrable Securities may reasonably request in writing (including, without limitation, making such reasonable representations as any such Holder may reasonably request), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitations of Rule 144 under the Securities Act and customarily taken in connection with sales pursuant to such exemptions. Upon the written request of any Holder of Registrable Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with the filing requirements of Rule 144.

Indemnification and Contribution.

The Company agrees to indemnify and hold harmless each Holder of Registrable Securities covered by the Resale Registration Statement, the directors, officers, employees, Affiliates and agents of each such Holder and each person who controls any such Holder within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (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 the Resale Registration Statement or in any amendment thereof, in each case at the time such became effective under the Securities Act, or in any preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, 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 (in the case of any preliminary Prospectus or the Prospectus, in the light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability 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 the party claiming indemnification specifically for inclusion therein. This indemnity shall be in addition to any liability that the Company may otherwise have.

Each Holder of securities covered by the Resale Registration Statement severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Resale Registration Statement and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each such Holder, but only with reference to information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement shall be acknowledged by each Notice Holder that is not the Buyers in such Notice Holder’s Notice and Questionnaire and shall be in addition to any liability that any such Notice Holder may otherwise have.

Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless such failure results in the forfeiture by the indemnifying party of substantial rights and defenses or otherwise materially prejudices the indemnifying party; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including one local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed

counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

If the indemnification to which an indemnified party is entitled under this Section 7 is for any reason unavailable to or insufficient although applicable in accordance with its terms to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative fault of the Company on the one hand and the Holders of the Registrable Securities on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Holder of the Registrable Securities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7(d). The aggregate amount of losses, liabilities, claims, damages, and expenses incurred by an indemnified party and referred to above in this Section 7(d) shall be deemed to include any out-of-pocket 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 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 7, no Holder of any Registrable Securities shall be required to indemnify or contribute any amount in excess of

the amount by which the proceeds received from the sale of the Registrable Securities by such Holder of Registrable Securities exceeds the amount of any damages that such Holder of Registrable Securities has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

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 7(d), each person, if any, who controls Buyers or any Holder of Registrable Securities 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 Buyers or such Holder, 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 shall have the same rights to contribution as the Company.

The provisions of this Section 7 shall remain in full force and effect, regardless of any investigation made by or on behalf of any Holder or the Company or any of the indemnified persons referred to in this Section 7, and shall survive the sale by a Holder of Registrable Securities covered by the Resale Registration Statement.

Miscellaneous

Successors and Assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective permitted successors and assigns. If any permitted transferee of any Holder shall acquire Registrable Securities, such Registrable Securities shall be subject to all of the terms of this Agreement and by taking and holding such Registrable Securities such person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement. Nothing in this Agreement is intended to confer upon any party other than the parties hereto or their respective permitted successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

Amendments and Waivers.

Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders of Registrable Securities may be given by Holders of at least a majority of the Registrable Securities being sold by such Holders pursuant to such Registration Statement; provided, that the provisions of this sentence may not be amended, modified, or supplemented except in

accordance with the provisions of the immediately preceding sentence. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 8(c), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder.

Severability. Any term or provision of this Agreement that is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the parties agree that the court making such determination shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws (as opposed to the conflicts of law provisions) of the State of Colorado.

Submission to Jurisdiction. The parties hereby submit to the non-exclusive jurisdiction of any court of the State of Colorado or the United States District Court for the District of Colorado for the purpose of any suit, action, or other proceeding arising out of this Agreement, and waive any and all objections to jurisdiction that they may have under the laws of the State of Colorado or the United States and any claim or objection that any such court is an inconvenient forum.

Entire Agreement. This Agreement constitutes the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof.

Counterparts. This Agreement may be executed in two or more counterparts (including by facsimile or similar means of electronic communication), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Specific Performance. Buyers and the Company each agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by them in accordance with the terms hereof and that each party shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity. Each party hereto expressly waives any requirement that any other party hereto obtain any bond or provide any indemnity in connection

with any action seeking injunctive relief or specific enforcement of the provisions of the Agreement.

Expenses. All reasonable, documented out-of-pocket costs and expenses incurred by the parties in connection with the negotiation, preparation, execution and delivery of this Agreement, including the fees, expenses and disbursements of legal counsel and accountants, shall be paid by the Company. Except as otherwise set forth in this Agreement, costs and expenses incurred by the parties in connection with the performance of its obligations under this Agreement shall be paid by the party incurring such expenses. The prevailing party in any litigation or other proceeding to collect Liquidated Damages pursuant to this Agreement shall be entitled to collect from the non-prevailing party all reasonable costs and fees associated with such litigation or proceeding, including reasonable attorneys’ fees.

Approval of Holders. Whenever the consent or approval of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its Affiliates (other than Buyers or subsequent Holders of Registrable Securities if such subsequent Holders are deemed to be such Affiliates solely by reason of their holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

Termination. This Agreement and the obligations of the parties hereunder shall terminate upon the earlier to occur of (i) the expiration of the Effectiveness Period or (ii) such time as there shall be no Registrable Securities.

Golden Minerals Company Lock-Up Agreement

Ladies and Gentlemen:

This letter agreement (this “Agreement”) is being delivered pursuant to that certain Common Stock Purchase Agreement (the “Stock Purchase Agreement”) by and between Golden Minerals Company, a Delaware corporation (the “Company”), Sentient Global Resources Fund III, LP, a Cayman Islands exempted limited partnership, and SGRF III Parallel I, LP, a Cayman Islands exempted limited partnership, and relates to the proposed initial public offering (the “Offering”) by the Company of its common stock, $0.01 par value per share (the “Stock”).

In order to induce you and the other underwriters for which you will act as representative (the “Underwriters”) to underwrite the Offering, the undersigned hereby agrees that, without the prior written consent of Xxxxxxx Xxxx & Company, LLC (the “Lead Manager”), during the period from the date hereof until one hundred eighty (180) 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 Stock, any other equity security of the Company or any of its subsidiaries and any security convertible into, or exercisable or exchangeable for, any Stock or other such equity security.

Notwithstanding the foregoing, the undersigned may transfer Relevant Securities by bona fide gift, will or intestate succession, provided, 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.

Notwithstanding the preceding paragraph, if (1) during the last 17 days of the Lock-Up Period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the Lock-Up Period the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by the immediately preceding paragraph shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Lead Manager waives, in writing, such extension. The undersigned acknowledges that the Company has agreed in the underwriting agreement for the Offering to provide notice to the undersigned of any event that would result in an extension of the Lock-Up Period pursuant to this paragraph, and the undersigned agrees that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned.

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 stock 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 stock register and other records relating to, such Relevant Securities. The undersigned hereby further agree that, except as provided in the Registration Rights Agreement between Buyers and the Company dated the date hereof, 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 if the Offering is not completed by March 31, 2010.

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.
