OTHER EVENTS On October 15, 1997, Coeur d'Alene Mines Corporation (the "Company") consummated the sale of $143,750,000 principal amount of its 7 1/4% Convertible Subordinated Debentures due 2005 (the "Debentures") to Lazard Freres & Co. LLC (the "Purchaser") pursuant to the terms of a Purchase Agreement, dated as of October 7, 1997, between the Company and the Purchaser (the "Purchase Agreement"). That amount includes $18,750,000 principal amount of the Debentures sold by the Company upon the Purchaser's exercise of an over-allotment option. The offering of Debentures was not registered under the Securities Act of 1933 (the "Act") and the Debentures were sold only to "qualified institutional buyers" in reliance upon Rule 144A under the Act and in offshore transactions in accordance with Regulation S under the Act and may not be offered or sold in the United States absent registration under, or the availability of an exception from the registration requirements of, the Act. The Debentures are convertible into shares of common stock, par value $1.00 per share, of the Company (the "Common Stock") on or before October 31, 2005, unless previously redeemed, at a conversion price of $17.45 per share, subject to adjustment in certain events. The Debentures are redeemable, in whole or in part, at any time on and after October 31, 2000 at the redemption prices set forth in the Indenture, dated as of October 15, 1997, (the "Indenture") between the Company and Bankers Trust Company, as trustee (the "Trustee"), plus accrued interest. The Debentures are required to be repurchased at the option of the holder if a "Designated Event" (as defined in the Indenture) occurs at 100% of their principal amount plus accrued interest. The Debentures are unsecured and subordinate in right of payment to all Senior Debt (as defined in the Indenture) and are also effectively subordinated to liabilities of the Company's subsidiaries. Pursuant to a Registration Rights Agreement, dated as of October 15, 1997, between the Company and the Purchaser, the Company is obligated to file with the Securities and Exchange Commission, and to use its best efforts to cause to become effective, a shelf registration statement covering resales of the Debentures and the shares of Common Stock issuable upon conversion thereof and to maintain the effectiveness of such registration statement until October 31, 1999, subject to adjustment in certain circumstances. The Company plans to use approximately $42.9 million of the estimated $138,942,500 net proceeds of the sale of Debentures to repay bank indebtedness and to use the balance of the net proceeds for other corporate purposes, including the possible acquisition of or investment in additional silver and gold mining properties or businesses. 2 ITEM 7.
