Item 1.02   Termination of a Material Definitive Agreement.

      By letter dated April 26, 2007 and received on April 27, 2007, Key
Pharmaceuticals, Inc. notified the registrant that it had terminated the License
Agreement between the parties dated March 13, 2000 as a result of its failure to
make royalty payments due under the agreement. The License Agreement granted
Hercon Laboratories Corporation, 98.5% of the outstanding stock of which is
owned by Transderm Laboratories Corporation, the right to use certain
intellectual property developed by Key, including technology covered by a US
patent, in the transdermal nitroglycerin patch products the company sells. The
letter demands that Hercon immediately cease manufacturing, using, importing and
selling drug-in-adhesive transdermal nitroglycerin patch products that
incorporate Key's technology.

      Transderm's board of directors continues to negotiate with Key in the hope
that it can enter into a settlement with Key as to the payment of the past due
royalties.
