FIRST PROSPECTUS SUPPLEMENT DATED FEBRUARY 13, 2004

(TO PROSPECTUS DATED OCTOBER 10, 2003)

 

Nanogen, Inc.

 

This document supplements the prospectus, dated October 10, 2003, relating to the resale by the selling security holders identified in the prospectus of 4,228,791 shares of our common stock, of which 2,107,580 shares are issuable upon the exercise of existing warrants. This prospectus supplement is not complete without, and may not be delivered or utilized except in connection with the prospectus, including any amendments or supplements thereto.

 

The following table supplements, or amends, as noted, the information contained in the table set forth in the prospectus under the caption “Selling Security Holders.” The table sets forth the number of shares beneficially owned by the selling security holders identified therein. Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting or investment power with respect to securities. The shares of common stock issuable upon the exercise of warrants exercisable within 60 days after February 13, 2004 are deemed outstanding and to be beneficially owned by the selling security holders holding such warrants. The percentage ownership for the selling security holders identified therein and the percentage ownership after this offering for each selling security holder are based on the assumptions that all of the shares being offered are sold pursuant to this offering, and that no other shares of common stock are acquired or disposed of by the selling security holders prior to the termination of this offering. The selling security holders may sell all, some or none of their shares or may acquire or dispose of other shares of common stock. Thus, we cannot estimate the aggregate number of shares that will be sold in this offering or the number or percentage of shares of common stock that the selling security holders listed in the table will own beneficially upon completion of the offering. The selling security holders, including their respective donees, transferees, pledgees or other successors-in-interest, may offer their shares of common stock for sale from time to time at market prices prevailing at the time of sale or at negotiated prices.
