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. THE HOLDER HEREOF, BY PURCHASING THESE SECURITIES, AGREES FOR THE BENEFIT OF [ISSUER] THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY: (A) TO [ISSUER], (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT (“REGULATION S”), (C) IN ACCORDANCE WITH (1) RULE 144A UNDER THE U.S. SECURITIES ACT, IF AVAILABLE, OR (2) RULE 144 UNDER THE U.S. SECURITIES ACT, IF AVAILABLE, (D) UNDER AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT, OR (E) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT, AND IN EACH CASE IN ACCORDANCE WITH APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES; PROVIDED THAT IN THE CASE OF TRANSFERS PURSUANT TO (C)(2) OR (E) ABOVE, A LEGAL OPINION SATISFACTORY TO [ISSUER] MUST FIRST BE PROVIDED.

provided that, if the Underlying Shares are being sold outside of the United States in accordance with Rule 904 of Regulation S at a time when Issuer is a “foreign issuer” as defined in Rule 902 of Regulation S, the legend may be removed by providing a duly completed and signed declaration to Issuer’s transfer agent for the Underlying Shares, or such other organization or entity performing such functions for Issuer (the “Transfer Agent”) to the following effect (or as the Issuer may from time to time prescribe) and, if required by the Transfer Agent, an opinion of counsel of recognized standing satisfactory to the Transfer Agent, acting reasonably, that such legend is no longer required under the applicable requirements of the U.S. Securities Act:

“The undersigned seller (i) acknowledges that the sale of the securities of [Issuer] to which this declaration relates is being made in reliance on Rule 904 of Regulation S (“Regulation S”) under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”) and (ii) certifies that: (A) it is not an affiliate (as defined in Rule 405 under the U.S. Securities Act) of [Issuer]; (B) the offer of the securities was not made to a person in the United States and either (1) at the time the buy order was originated, the buyer was outside the United States, or the seller and any person acting on its behalf reasonably believed that the buyer was outside the United States, or (2) the transaction was executed on or through the facilities of the TSX, and neither the seller nor any person acting on its behalf knows that the transaction has been prearranged with a buyer in the United States; (C) neither the seller nor any affiliate of the seller nor any person acting on any of their behalf has engaged or will engage in any “directed selling efforts” (as such term is defined in Regulation S) in the United States in connection with the offer and sale of the securities; (D) the sale is bona fide and not for the purpose of “washing off” the resale restrictions imposed because the securities are “restricted securities” (as that term is defined in Rule 144(a)(3) under the U.S. Securities Act); (E) the seller does not intend to replace the securities sold in reliance on Rule 904

of Regulation S with fungible unrestricted securities; and (F) the contemplated sale is not a transaction, or part of a series of transactions which, although in technical compliance with Regulation S, is part of a plan or scheme to evade the registration provisions of the U.S. Securities Act.”;

and provided further, that if any Underlying Shares are being sold to a purchaser in the United States in accordance with Rule 144 under the U.S. Securities Act, the legend may be removed by delivery to the Transfer Agent of an opinion of counsel of recognized standing, satisfactory to the Issuer, acting reasonably, to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act;

(ii) the certificates representing Notes also will bear the following legend denoting the restrictions on transfer under Applicable Securities Laws (including, but not limited to, National Instrument 45-102 — Resale of Securities):

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY OR ANY COMMON SHARES ISSUED ON A CONVERSION OF ANY PRINCIPAL AMOUNT OF THIS SECURITY (OR INTEREST THEREON) BEFORE [INSERT THE DATE THAT IS FOUR MONTHS AND A DAY AFTER THE DISTRIBUTION DATE OF NOTES].

and, if at the date of the conversion of Notes the applicable restriction period has not expired, the certificates representing the Underlying Shares will bear such legend as well; and

(iii) in addition to the foregoing legends, the certificates representing the Underlying Shares shall, until the date that is four months and a day after the Closing Date, bear, in addition to any legend(s) required by Canadian securities laws and policies, the following legend:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF THE 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.

(d) the Subscriber will not sell, assign or transfer the Securities except in accordance with the provisions of Applicable Securities Laws and Exchange rules, if applicable, that are in effect as the time of such sale, assignment or transfer.

7.3 The Subscriber also acknowledges that it has been advised to consult its own legal advisors with respect to applicable resale restrictions and that it is solely responsible (and the Issuer is not in any manner responsible) for complying with such restrictions.

ECU Silver Mining Inc.

Convertible Senior Unsecured Notes

Exhibit A — Limitations on Uses
(all dollar amounts herein refer to Canadian currency)

June 24, 2011

Guiding Principals		· ECU Silver Mining Inc. (“ECU”) shall rely on operating cash flow, including cash flow generated from the sale of concentrates and doré produced at the Velardeña Property, as the primary source of funding ECU’s operations. · To the extent ECU’s operating cash flow is inadequate to fund the operating and capital cash requirements, ECU may use the proceeds from the Notes issuance to fund such shortfall. · ECU and Golden Minerals Company (the “Holder”) acknowledge that ECU shall maintain a cash balance of no less than $1.0 million at all times; provided, however, that failure by ECU to maintain such minimum balance shall not constitute a breach of this Exhibit A.

Permitted Uses		· Permitted uses (the “Permitted Uses”) of Escrowed Proceeds (defined below) shall include the following costs and expenses reasonably estimated by ECU to be incurred by it within 30 days following a request for disbursement from the Escrowed Proceeds: · expenses associated with development, exploration, operating and general and administrative costs (including base salaries and employee benefits) relating to the development and operating activities at the Velardeña Property; · general and administrative expenses, including base salaries, employee benefits and the various expenses incurred in connection with the transactions contemplated by the Arrangement Agreement, dated June 24, 2011, by and between Holder and ECU; · Regularly scheduled principal and interest payments on arm’s length indebtedness existing at the date of the Notes issuance; and · Such other expenditures (including funding any deficit in the minimum cash balance) as may be approved by the Holder. · Unless approved by the Holder, Escrowed Proceeds shall not be used for payments to employees, officers or directors other than for base salaries, including employee benefits, in the ordinary course. Bonus payments, severance payments, change of control payments, or other termination or extraordinary payments shall not be considered compensation in the ordinary course.

Escrow		· The proceeds from the Notes shall be deposited in an escrow account (the “Escrowed Proceeds”). · The escrow agent (the “Escrow Agent”), to be appointed upon the mutual consent of ECU and the Holder, shall disburse the Escrowed Proceeds in accordance with the escrow agreement to be entered into in connection with

the Notes issuance.

Disbursement of Escrowed Proceeds

· Use of Escrowed Proceeds from the escrow account will be controlled by the following cash draw process:

I. Draw requests will be in increments of no fewer than $250,000 until all of the Escrowed Proceeds have been drawn. The last draw may be for less than $250,000 if it represents the remaining Escrowed Proceeds in the escrow account.

a. The initial draw request from the escrow account must include a schedule of cash payments (including, for greater certainty, the Permitted Uses thereof) to be made with the following detail provided:

1. All individual payments equal to or greater than $15,000 to any one payee must be separately highlighted, with the expected payment date listed;

2. Total payments to any one payee of less than $15,000 can be grouped together into one “other” amount except that should such amount exceed $50,000, payments to any one payee for less than $15,000 should be separately identified, in order of largest to smallest, until the aggregate of all remaining payments to any one payee for less than $15,000 totals $50,000 or less;

3. Notwithstanding 2. above, payments to any of the following payees must be separately identified, regardless of amount:

(a) All payments made to employees or directors other than for normal payroll or employee benefit plans. For clarity, bonuses, severance or other termination or extraordinary payments will not be considered normal payroll;

(b) Any amounts paid on indebtedness of the Company; and

b. All subsequent draw requests must be prepared in the same manner as the initial draw request and be accompanied by an additional schedule reconciling actual spending to the amounts forecast in previous draw requests submitted and approved by the Holder. Line item variances greater than $10,000 or 10% of the amount forecast must include explanations as to the cause of the variance. If additional amounts remain to be paid on items included in a previous draw request, a forecast should be made of the expected amount and time for the payment.

· If, within 5 business days after receiving a disbursement request, (i) the Holder

approves the disbursement of the requested amount of Escrowed Proceeds or does not file a claim of default (a “Claim of Default”) with the Escrow Agent and ECU, the Escrow Agent shall disburse the Escrowed Proceeds immediately following approval of the Holder or the lapse of 5 calendar days, whichever is sooner, or (ii) the Holder has rejected a disbursement request by filing a disapproval notice (a “Disapproval Notice”) with the Escrow Agent and ECU on the basis that all or a portion of such request is not for a Permitted Use, the requested funds which are alleged not to be for a Permitted Use will not be disbursed.

Events of Default

· In an “Event of Default,” the Escrow Agent shall suspend all further disbursements of the Escrowed Proceeds and, at the request of the Holder, return all remaining Escrowed Proceeds to the Holder, provided that the Notes relating to the returned Escrowed Proceeds shall automatically be cancelled.

· An Event of Default shall include the following:

· ECU fails to materially comply with the process contemplated herein; or

· distributed Escrowed Proceeds are applied toward expenses other than for Permitted Uses or in material variance from what was set forth in the applicable disbursement request.

· In order to claim an Event of Default, the Holder must file a Claim of Default with the Escrow Agent and ECU detailing the reasons for the alleged default.

· Upon receipt of a Claim of Default or Disapproval Notice, ECU shall have 15 calendar days to file with the Escrow Agent and the Holder a challenge to the Claim of Default or Disapproval Notice and / or cure the alleged default (the “Challenge”). Any Challenge shall be accompanied by a detailed explanation for the reasons therefore. If the Holder does not dispute ECU’s Challenge within 5 calendar days, the Claim of Default or the Disapproval Notice will be deemed to have been withdrawn with prejudice.

· In the absence of a Challenge, the Claim of Default shall automatically become an Event of Default or the Disapproval Notice shall be deemed final and binding.

· If the Holder files a response to the Challenge within the prescribed time period (the “Holder Response”), the dispute will be referred to a mutually acceptable third-party arbiter (the “Arbiter”) within 3 days of the Holder Response and

(a) with respect to a Claim of Default, all further disbursements of Escrowed Proceeds shall be stayed until final resolution of the Claim of Default; and

(b) with respect to a Disapproval Notice, the requested funds which are alleged not to be for a Permitted Use shall be stayed until final resolution of the Disapproval Notice.

· The Arbiter will be charged with evaluating the Claim of Default or Disapproval Notcie, as the case may be, the Challenge, and the Holder Response and finalizing a decision within 30 calendar days of being engaged, such decision to be final and non-appealable.

· The costs and expenses of the Arbiter shall be borne by the losing party or, where the Arbiter’s decision takes exception to each of the parties’ positions, by both parties equally.
