Summary of COEUR D ALENE MINES CORP

Item 1.01. Entry into a Material Definitive Agreement.

Arrangement Agreement

On February 20, 2013, Coeur d'Alene Mines Corporation (the "Company" or "Coeur") entered into an Arrangement Agreement (the "Arrangement Agreement"), among the Company, 0961994 B.C. Ltd., a corporation wholly-owned by the Company and incorporated under the laws of British Columbia ("Subco"), and Orko Silver Corp., a corporation incorporated under the laws of British Columbia ("Orko"), pursuant to which the Company will acquire (the "Arrangement") all of the issued and outstanding common shares of Orko (the "Orko Shares") pursuant to a plan of arrangement (the "Plan of Arrangement") under the Business Corporations Act (British Columbia). The consummation of the Arrangement is subject to approval by the Supreme Court of British Columbia (the "Court") and other customary closing conditions described further below.

Pursuant to, and subject to the terms and conditions of, the Arrangement Agreement and the Plan of Arrangement, Orko shareholders (the "Orko Shareholders") may elect to receive in exchange for each Orko Share: (i) 0.0815 common shares of Coeur (the "Coeur Shares"), CAD$0.70 cash and 0.01118 conditioned warrants to purchase Coeur Shares (the "Coeur Warrants");
(ii) 0.1118 Coeur Shares and 0.01118 Coeur Warrants, subject to pro-ration as to the number of Coeur Shares if the total number of Coeur Shares elected by Orko Shareholders exceeds approximately 11.6 million; or (iii) CAD$2.60 in cash and
0.01118 Coeur Warrants, subject to pro-ration as to the amount of cash if the total cash elected by Orko Shareholders exceeds CAD$100 million. If all Orko Shareholders elect either the all cash (and Coeur Warrants) or the all share (and Coeur Warrants) alternative, each Orko Shareholder would receive 0.0815 Coeur Shares and CAD$0.70 in cash, together with 0.01118 Coeur Warrants, for each Orko Share. One whole Coeur Warrant is expected in certain circumstances, including the effectiveness of a registration statement with respect to underlying Coeur Shares (to the extent required by applicable U.S. securities laws), to be exercisable for one whole Coeur Share for a period of four years commencing on the later of (i) the date the Arrangement is consummated and
(ii) the date that the U.S. Securities and Exchange Commission (the "SEC") initially declares effective a registration statement qualifying the Coeur Shares issuable on exercise of the Coeur Warrants, at an exercise price of US$30.00, all subject to adjustment in accordance with the terms of the Coeur Warrant. The Company has agreed to use commercially reasonable efforts to register the Coeur Shares issuable upon the valid exercise of the Coeur Warrants under applicable U.S. securities laws and have the Coeur Warrants listed on the Toronto Stock Exchange and the New York Stock Exchange, but the completion of such registration and listings will not be a closing condition of the Arrangement.

The parties have agreed to use commercially reasonable efforts to make any necessary amendments to the Agreement and the Plan of Arrangement, prior to the mailing of the management proxy circular to Orko Shareholders, to permit Orko Shareholders who are residents of Canada and who would receive Coeur Shares under the Arrangement to receive, instead of each Coeur Share that they would otherwise receive under the Plan of Arrangement, one share of a Canadian-incorporated subsidiary of Coeur that is exchangeable into one Coeur Share (collectively, the "Exchangeable Shares"). The Exchangeable Shares
(i) shall be exchangeable for a period of five years from the date of issue provided that 500,000 Exchangeable Shares remain outstanding and (ii) shall not be listed or quoted on any exchange or market. The Company has agreed to use commercially reasonable efforts to register the Coeur Shares issuable on exchange of the Exchangeable Shares (to the extent required by applicable U.S. securities laws), but the completion of such registration will not be a closing condition of the Arrangement.

Consummation of the Arrangement is subject to various closing conditions, including, among others: (i) the approval of the Arrangement by no less than two-thirds of the Orko securityholders, voting as a single class, voting at a special meeting to be called to consider the Arrangement (the "Orko Meeting") and any other necessary actions related thereto; (ii) obtaining from the Court an Interim Order and Final Order (as both terms are defined below) on terms satisfactory to each of Coeur and Orko; (iii) obtaining all antitrust clearances . . .

Item 3.02. Unregistered Sales of Equity Securities.

As described in Item 1.01 above, the Company has agreed in the Arrangement Agreement that, if the Plan of Arrangement becomes effective and its acquisition of the Orko Shares is thereby completed, the Company may issue, as consideration for all of the issued and outstanding Orko Shares: (i) depending on the elections of the Orko Shareholders, a combination of Coeur Shares and conditioned Exchangeable Shares not to exceed 11,600,000 in the aggregate and
(ii) 1,160,000 conditioned Coeur Warrants. Upon the fulfillment of certain conditions, the Exchangeable Shares are expected to be exchangeable on a one-for-one basis for Coeur Shares and the warrants are expected to be exercisable for up to 1,160,000 Coeur Shares.

Section 3(a)(10) of the Securities Act of 1933, as amended (the "Securities Act"), exempts from the registration requirements under the Securities Act the issuance and exchange of securities which have been approved, after a hearing upon the fairness of the terms and conditions on which all persons to whom it is proposed the securities will be issued shall have the right to appear, by any court expressly authorized by law to grant such approval. Under the Arrangement Agreement, Orko will submit the Plan of Arrangement to the Court for the Interim Order permitting notice to all persons to which the Coeur Shares, Coeur Warrants and Exchangeable Shares, as applicable, will potentially be issuable. Following the requisite approval by the Orko Shareholders and a hearing at which such persons will have the right to appear, Orko will seek the Final Order from the Court as to the fairness of the Plan of Arrangement. The Final Order is a condition to the consummation of the Plan of Arrangement and the issuance of the Coeur Shares, Coeur Warrants and Exchangeable Shares, as applicable. The Company therefore anticipates that, if the Plan of Arrangement becomes effective under the terms and conditions described in the Arrangement Agreement (including the receipt of the Final Order from the Court), the issuance of the Coeur Shares, Coeur Warrants and Exchangeable Shares, as applicable, to the Orko Shareholders upon the consummation of the Arrangement will be exempt from the registration requirements under the Securities Act pursuant to Section 3(a)(10) thereof. To the extent other exemptions from registration under the Securities Act are available in connection with the securities to be issued pursuant to the Arrangement, Coeur and Subco may also choose to rely upon such exemptions.

Item 7.01. Regulation FD Disclosure.

Promissory Note

In connection with the Arrangement Agreement, on February 20, 2013, Orko executed and delivered a promissory note (the "Note") in the principal amount of CAD$11,600,000 in favor of the Company in connection with the Company's payment, on behalf of Orko, of the termination fee due to First Majestic Silver Corp. ("First Majestic") pursuant to Orko's and First Majestic's arrangement agreement, dated as of December 16, 2012 (the "First Majestic Arrangement Agreement"). Orko and First Majestic terminated the First Majestic Arrangement Agreement in accordance with its terms on February 20, 2013. The indebtedness due under the Note will not accrue interest. The Note has a maturity date of August 20, 2014; provided, however, that earlier repayment may be required upon the occurrence of certain events of default or upon a Termination Payment becoming payable pursuant to the Arrangement Agreement. The Note includes customary representations, warranties and covenants by the parties thereto.

Subject to the terms and conditions set forth in the Note, Orko is entitled, at is option, upon the indebtedness under the Note becoming due and payable on any date, so long as (i) the indebtedness has not become due and payable on such date as a result of certain events of default and (ii) the Termination Payment under the Arrangement Agreement is not payable on such date, to convert all of the principal amount of the indebtedness into common stock of Orko (the "Borrower Stock"). The indebtedness will be convertible into Borrower Stock at a price per share equal to CAD$2.25 (such price, subject to adjustment, the "Conversion Price"), and the number of Borrower Stock to be deliverable to the Company upon conversion will be equal to the quotient of (x) the amount of indebtedness under the Note divided by (y) the Conversion Price.

Coeur Shares issuable upon (i) the exercise of Coeur Warrants to be issued by Coeur in connection with the proposed Transaction and (ii) the exchange of Exchangeable Shares to be issued by a subsidiary of Coeur in connection with the proposed Transaction may be registered pursuant to a registration statement on Form S-1 to be filed with the SEC or issued pursuant to an available exemption. This information is not a substitute for any registration statement or any other document that Coeur may file with the SEC or send to its shareholders in connection with the offer and/or issuance of Coeur Shares in connection with the exercise of the Coeur Warrants and exchange of the Exchangeable Shares. Investors who may receive Coeur Warrants or Exchangeable Shares in the Transaction are urged to read Coeur's registration statement on Form S-1, if and when filed, including the prospectus, and all other relevant documents that may be filed with the SEC as and if they become available because they will contain important information about the issuance of Coeur Shares upon the exercise of any Coeur Warrants and exchange of any Exchangeable Shares.
