This
Second Amendment to Security Agreement (this Amendment) effective as of January 1, 2003, by and between Polar Molecular Corporation, a Delaware corporation (the Company), and each of the employees and advisors of the
Company set forth on Exhibit A hereto (collectively, the Secured Parties) hereby amends the Security Agreement dated as of January 30, 2002, by and between the Company and the Secured Parties, as amended (the

security interest granted to the Secured Parties pursuant to the Security Agreement.



NOW, THEREFORE, in consideration of the promises set forth therein and herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company hereby agrees as

read in its entirety as follows:
