(1) Also includes any sale of the debentures and the underlying common stock by pledgees, donees, transferees or other successors in interest that receive such securities by pledge, gift, distribution or other non-sale related transfer from the named selling securityholders. Information about other selling securityholders will be set forth in prospectus supplements

	or in other documents that we file from time to time with the Securities and Exchange Commission that are incorporated by reference in this prospectus, if required. See “Where You Can Find More Information.”
(2)	Assumes conversion of all of the selling securityholder’s debentures at a conversion rate of 37.8508 per $1,000 principal amount at maturity of debentures and a cash payment in lieu of the issuance of any fractional share interest. However, this conversion rate is subject to adjustment as described under “Description of Debentures-Conversion Rights.” As a result, the number of shares of common stock issuable upon conversion of the debentures may increase or decrease in the future.
(3)	Reflects rounding down of fractional common stock issuable to each selling securityholder upon conversion of the debentures.
(4)	Calculated based on Rule 13d-3 of the Securities Exchange Act of 1934, as amended, using 54,226,350 shares of common stock outstanding as of March 7, 2004. In calculating this amount, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that particular holder’s debentures. However, we did not treat as outstanding the common stock issuable upon conversion of any other holder’s debentures.

Our common stock is quoted on the Nasdaq National Stock Market under the symbol “EFII.” On April 1, 2004, the last reported sale price of our common stock was $24.95 per share.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined that this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.
