With this Amendment, the termination date of the Agreement has been extended to March 31, 2006, subject to Kinross filing its financial statements no later than December 31, 2005. The transaction is subject to regulatory approvals, a minimum two-thirds approval at a special meeting of Crown shareholders and other customary closing conditions. Both parties are working to close the transaction as rapidly as possible. Under the terms of the Amendment, shareholders of Crown will receive 0.34 shares of Kinross for each share of Crown, an increase of 0.0489 over the original exchange ratio of 0.2911. A valuation collar has also been agreed upon in which the aggregate maximum value of Kinross common shares to be issued to Crown shareholders is US$110 million and the minimum value is US$77.5 million, excluding shares held by Kinross. Kinross has also agreed to purchase a US$10.0 million convertible debenture (the "Debenture") from Crown. The Debenture is convertible into 5.8 million shares of Crown. In the event the Agreement is terminated, Crown shall have the right to convert all amounts due under this Debenture by providing 30 days prior notice to Kinross. Assuming all of the outstanding Crown warrants and options are converted, a total of approximately 16.6 million common shares of Kinross will be issued upon the completion of the transaction. Tye Burt, President and C.E.O. of Kinross said "We are driving hard to complete the appropriate filings to make this transaction happen. We remain 100% committed to the deal, and look forward to starting work on the property as soon as possible."

Under the terms of the Amendment to the Agreement, shareholders of Crown will receive 0.34 shares of Kinross for each share of Crown, an increase to the original exchange ratio of 0.2911. A valuation collar has also been agreed upon whereby the aggregate maximum value of Kinross common shares to be issued to Crown shareholders is US$110 million and the minimum value is $77.5 million. Crown shares held by Kinross are not included in the valuation calculation. The transaction is subject to regulatory approvals, a minimum two-thirds approval at a special meeting of Crown shareholders and other customary closing conditions. With this Amendment, the termination date of the Agreement has been extended to March 31, 2006 except that, if Kinross has not filed its 2004 audited financial statements with the Securities and Exchange Commission on or before December 31, 2005, the termination date of the Agreement will be December 31, 2005. The Agreement was due to expire on May 31, 2005, but additional time is necessary for Kinross to complete its corporate filings with the Securities and Exchange Commission ("SEC") and completion and SEC acceptance of a definitive registration statement. Kinross has also agreed to fund a US$10.0 million convertible debenture ("Debenture") investment into Crown. Funds from the investment may be used to pay a special dividend to Crown shareholders of up to $0.21 per share of Crown before September 30, 2005. The special dividend, if one is declared, will be determined by Crown's board of directors based upon the future financial requirements of Crown. Payment of the special dividend will change the tax status of the transaction from tax-deferred to taxable. Neither the financing nor any conversion of the Debenture will affect the exchange ratio of 0.34 shares of Kinross common stock for each share of Crown that was set in the Amendment. The Debenture will have a term of five years, an interest rate of 4% payable annually with a provision to forego interest for the first two annual payments, at Crown's election. The Debenture is convertible into 5.8 million shares of Crown, plus accrued interest. In the event the Agreement is terminated other than as a result of a default by Crown, Crown shall have the right to convert all amounts due under the Debenture by providing 30 days prior notice to Kinross. Crown currently has approximately 40.0 million shares outstanding and 48.3 million on a fully diluted basis, both amounts excluding 0.5 million shares currently held by Kinross and shares that could be issued to Kinross upon the conversion of the Debenture.
