This Amendment with the Effective Date of December 15, 2000 is to the License Agreement dated May 9, 1996 between Sangamo BioSciences, Inc. and Massachusetts Institute of Technology, which was amended on December 10, 1997, December 2, 1998, September 1, 1999 and February 10, 2000.

The parties thereto now further agree as follows:

and;

any product, compound or derivative thereof that, in the absence of the use of PATENT RIGHTS relating to M.I.T. Case No. 8775H would not have been discovered, identified, selected or determined to have biological activity or utility for commercial use (hereinafter “IDENTIFIED PRODUCTS”).

(a) LICENSEE shall pay M.I.T. an Amendment Issue Fee of $[***], payable as follows:

*** CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION

(c) For sublicenses granted to M.I.T. Case No. 8775H, the Sublicense Issue Fees due under Paragraph 4.1(h) shall be [***] dollars ($[***]) per sublicense and the Sublicense Maintenance Fees shall be [***] dollars ($[***]) per sublicense.

(d) LICENSEE shall be responsible for payment of seventy-five percent (75%) of all fees and costs relating to the U.S. filing, prosecution and maintenance of M.I.T. Case No. 8775H and 100% of all fees and costs relating to foreign filing prosecution and maintenance of Case No. 8775H whether such fees and costs were incurred before or after the effective date of this Amendment. In the case of any divisionals, continuations, continuation-in-part applications to the extent the claims are directed to subject matter specifically described in M.I.T. Case No. 8775H and confined solely to claims involving protein-DNA interactions (exclusive field in Section 3(a)(i) above), LICENSEE shall have the primary responsibility for filing, prosecution and maintenance of such patent applications. LICENSEE shall seek broad claims in prosecuting such claims, with M.I.T.’s review and approval, such approval not to be unreasonably withheld. LICENSEE shall provide guidance to patent counsel on prosecution matters, with ultimate decisionmaking authority resting with M.I.T. In the case of foreign filings, LICENSEE shall have the right to determine in which territories it will file, and inform M.I.T. on a timely basis of such decisions. If LICENSEE elects to drop coverage in a country or countries, it shall inform M.I.T. on a timely basis, and M.I.T. at its sole discretion may assume these costs. LICENSEE shall receive copies of all documents relating to the U.S. or foreign filing, prosecution and maintenance of M.I.T. Case No. 8775H and all derivative patents and patent applications.

(e) Paragraph 4.1(c) shall be amended to read in its entirety Running Royalties in an amount equal to [***] Percent ([***]%) of NET SALES of the LICENSED PRODUCTS and LICENSED PROCESSES used, leased or sold by and/or for LICENSEE and/or its sublicensees, except that if the PATENT RIGHTS of only case 8775H cover the LICENSED PRODUCT then:

(f) Running Royalties due under Paragraph 4.1(c), shall be as follows:
