                        PRODUCT RIGHTS TRANSFER AGREEMENT

The Product Rights Transfer Agreement ("Agreement"), is made and effective this
24th day of May, 1996 by and between Advanced Materials, Inc. ("Grantor"). a
California Corporation and Wilshire Technologies, Inc. (Grantee"), a California
Corporation.

Whereas, pursuant to an Asset Purchase Agreement dated November 23, 1993 (the
"Original Agreement"), the Grantee sold its OEM medical division to the Grantor;
and

Whereas, certain Products were included in that sale; and

Whereas, the Grantee wishes to purchase the rights to certain Products from the
Grantor;

NOW, THEREFORE, in consideration of the mutual agreements and promises set forth
herein, the parties agree as follows:

1. RIGHTS GRANTED.

         Grantor hereby conveys to Grantee, its successors and permitted assigns
         the exclusive right to manufacture, use, inventory, promote, market,
         sell and/or resell such of the Grantor's Products as are defined in the
         following section.

2. PRODUCTS.

         As used in this Agreement, the term "Product" or "Products" will refer
         exclusively to the following part numbers or derivative part numbers or
         directly derivative Products:

         NDM #5557                          NDM #5631
         NDM #5413                          NDM #5432

3. PAYMENT.

         As compensation for the rights granted by this Agreement, the Grantee
         agrees to pay the Grantor the total amount of $50,000. The "Payment" is
         calculated by multiplying (a) the number of units of the Product sold,
         or estimated to be sold, by the Grantee during the period May 17, 1995
         to May 16, 1998, by (b.) one and one half cent ($0.015) per unit. The
         calculation of the Payment is attached as Exhibit A.

         The payment shall be made as a reduction of $50,000 in the amount due
         from Grantor to Grantee pursuant to the Promissory Note dated November
         23, 1993.

4. RIGHTS TRANSFER.

         Upon execution of this agreement and the completion of the Payment
         under Section 3 by an amendment to the Promissory Note dated November
         23, 1993, all rights, title and interest to the Products will pass to
         the Grantee without further payment or obligation to the Grantor.

         5.1 By Grantor. Grantor represents and warrants that, except for 
         any matters disclosable by Grantee to Grantor pursuant to the
         Original Agreement, and to the knowledge of Steve F. Scott and J.
         Douglas Graven without independent inquiry, the exercise by Grantee of
         the rights granted in Section 1 hereof will not infringe any valid
         enforceable patent rights of third parties and will not violate any
         other intellectual property rights of third parties. Grantor agrees to
         protect Grantee and hold Grantee harmless from any loss, damage or
         claim arising from the breach of the representation and warranty

         Grantee or others with respect to the Products, either express or
         implied, including, without limitation, the implied warranties of
         merchantability of fitness for a particular purpose.

         5.2 By Grantee. Except as otherwise provided in Section 5.1, Grantee
         agrees to protect Grantor and hold Grantor harmless from any loss,
         damage or claim arising from the Grantee's exercise of any right
         granted under this agreement. This indemnification includes any
         representation or warranty made by grantee or its agents, employees or
         representatives to customers, users or third party consumers of the
         Products.

7. ASSIGNMENT.

         Neither this Agreement nor any right or interest in the Agreement 
         may be assigned without the express written approval of the Grantor, 
         except that no approval is required for the assignment to Horizon 
         Medical, Inc. or its subsidiaries of the rights (except the rights 
         under Section 5.1) granted under this Agreement.

         With regard to the Products, this Agreement shall constitute the entire
         understanding between the Grantor and Grantee and supersedes any
         previous communications, representations or agreements, whether oral or
