Item 1.01

Entry into a Material Definitive Agreement.

On January 16, 2009, Nanogen, Inc. (the “Company”) entered into a Consent and Waiver with Financière Elitech SAS (“Elitech”) and stockholders of Elitech (“Sellers”) to waive certain obligations of the Company and Elitech under the Share Exchange Agreement, dated as of August 14, 2008, between the Company, Elitech and Sellers (the “Share Exchange Agreement”). Pursuant to the Consent and Waiver, Elitech and Sellers agree to waive, among other things, the Company’s obligations not to solicit, negotiate or implement any third party proposal for acquisition transaction with respect to the Company, and consent to the Company engaging in such solicitation activities. Under the Consent and Waiver, the Company agrees to waive, among other things, Elitech’s obligations to prepare, as soon as practicable after the date of the Share Exchange Agreement, audited consolidated financial statements and other financial statements of Elitech and its subsidiaries as requested by the Company in order to comply on a timely basis with applicable federal securities laws. Instead, Elitech agrees to use reasonable commercial efforts to prepare such financial statements as required under the Share Exchange Agreement and may suspend or termination such preparation if it deems commercially reasonable to do so. If Elitech suspends or terminates the preparation of such financial statements, the Company will not be obligated to pay certain termination and reimbursement fees to Elitech under the Share Exchange Agreement.

As previously disclosed in a Form 8-K filed on August 15, 2008, the Company and Elitech proposed to combine the two companies pursuant to the terms of the Share Exchange Agreement (the “Business Combination”). If the Business Combination is not consummated by March 31, 2009, each party has the right to terminate the Share Exchange Agreement. The Company, Elitech and Sellers acknowledge that, despite their best efforts and due to events beyond their control, it has become unlikely that the Business Combination will be completed by March 31, 2009. As such, the parties believe that it is in the best interest of all participants to enter into the Consent and Waiver to remove certain restrictions on the Company with respect to its solicitation activities, and to waive certain obligations of the parties under the Share Exchange Agreement.

The foregoing is a summary description of certain terms of the Consent and Waiver. It is qualified in its entirety by the text of a copy of such document attached as exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
