13.2                        Notwithstanding the foregoing, the provisions of Sections 6, 7 and 12 shall survive any termination or expiration of this Agreement and the provisions of Section 2 shall survive any expiration or termination of this Agreement except for material breach by Affymax.  Termination of this Agreement or the License shall not relieve Affymax of liability for any portion of the Settlement Fee accruing prior to such termination or any Royalty with respect to sales occurring prior to such termination.
