PART III -- NARRATIVE State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, or the transition report portion thereof, could not be filed within the prescribed time period. EMCORE has determined, based on consultation with its auditors, that the gain realized upon the retirement in February 2004 of approximately $146 million aggregate principal amount of its 5% Convertible Subordinated Notes due May 2006 in exchange for approximately $80.3 million of its new 5% Convertible Senior Subordinated Notes due May 15, 2011 and approximately 7.7 million shares of its common stock should be classified as other income (under "Other expenses") rather than as operating income (under "Operating expenses") in its statement of operations. Accordingly, we require additional time to revise our Quarterly Report on Form 10-Q for the quarter ended March 31, 2004. This reclassification does not affect EMCORE's balance sheet or statement of cash flows and has no effect on our previously reported earnings per share or net worth. We expect to file this Form 10-Q shortly. PART IV-- OTHER INFORMATION (1) Name and telephone number of person to contact in regard to this notification Howard W.
