        11.2    Procedure. Licensor's indemnification obligations set forth in
Section 11.1 shall be contingent upon: (i) Licensor promptly notifying Licensee

conditions of that certain Mutual Confidentiality and Disclosure Agreement dated
November 27, 2000 ("NDA") in connection with all Confidential Information (as
defined in the "NDA" and modified herein) contemplated under this Agreement.
