Exhibit 10.3 COLLATERAL ASSIGNMENT COLLATERAL ASSIGNMENT (this "Assignment") dated January 14, 2000 from CLINICAL NEURO SYSTEMS HOLDINGS LLC, a Delaware limited liability company (the "Assignor"), to CLINICAL NEURO SYSTEMS, INC., a Delaware corporation ("CNS"), and GEORGE J. CONNELL ("Connell"; together with CNS, the "Assignee"). BACKGROUND A. The Assignor and the Assignee are parties to an Asset Purchase Agreement dated as of January 14, 2000 (the "Asset Purchase Agreement"), pursuant to which the Assignor is purchasing substantially all of the assets of CNS for $4,004,000 in cash plus a secured promissory note (the "CNS Note") in the principal amount of $2,800,000. B. Assignor is the holder of a subordinated promissory note payable to Assignor by its sole member, Integra LifeSciences Corporation ("Integra"), in the principal sum of $2,800,000 (the "Integra Note"), which represents a contribution of capital by Integra to Assignor, its wholly owned subsidiary. C. Assignor intends to secure its obligations under the CNS Note, in part, by assigning the Integra Note to Assignee as collateral pursuant to this Agreement. D. CNS is willing to accept the CNS Note in payment of a portion of the purchase price under the Asset Purchase Agreement only on the condition that the Assignor executes and delivers this collateral assignment of the Integra Note to Assignee. E. CNS intends to liquidate and dissolve promptly after the date of this Agreement, whereupon CNS intends to distribute the CNS Note and the Integra Note and its rights under the Asset Purchase Agreement and this Agreement to George J. Connell as its sole stockholder, and upon such distribution, George J. Connell shall be the sole Assignee hereunder. NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby agree as follows: 1. Assignment. (a) As security for the repayment of the CNS Note and the performance and satisfaction of all other obligations of the Assignor under the CNS Note, Assignor hereby collaterally assigns, transfers and sets over to the Assignee and grants to the Assignee a security interest in and to all of Assignor's right, title, and interest in and to the Integra Note and all monies due and to become due under the Integra Note, and all rights, remedies and benefits arising thereunder, with full power and right in the Assignee's own name or in Assignor's name to take all such legal or other action as may be necessary to enforce the provisions of the Integra Note; (b) Upon the occurrence and during the continuance of an event of default under the CNS Note, Assignor irrevocably appoints the Assignee its attorney, with power of substitution, to sue for, receive, collect, compromise and adjust, and give releases for the monies due or to become due, and authorizes and empowers the Assignee to endorse Assignor's name on, and collect, all checks or other proceeds received by the Assignor under the Integra Note. 2. Payments under the Note. Until the occurrence of an event of default under the CNS Note, all payments under the Integra Note shall be made to Assignor. Upon the occurrence and during the continuance of an event of default under the CNS Note, at the Assignee's discretion, all payments under the Integra Note (whether upon demand or otherwise) shall be made to the Assignee and shall be applied by the Assignee against the sums due under the CNS Note, and the Assignee shall be permitted to take all actions to collect all payments under the Integra Note.
