   Washington, DC

LITIGATION RELEASE NO. 15723 / April 28, 1998

   SECURITIES AND EXCHANGE COMMISSION v. Technigen Corporation, et. al.,
   Civil Action No. 98-S-933 (USDC D. Colo.)

   The Commission announced the filing of a complaint alleging a scheme
   to manipulate the market price of two microcap companies, Technigen
   Corporation ("Technigen") of Vancouver, British Columbia, and TV
   Communications Network, Inc. ("TVCN") of Englewood, Colorado.
   According to the Commission's complaint, filed in federal district
   court in Denver, Colorado on April 27, 1998, the objective of the
   manipulations was to support the market in both stocks to profitably
   absorb substantial distributions of unregistered stock which the
   defendants carried out from January 1992 through May 1993. While the
   manipulative scheme was ongoing, the price of both stocks remained in
   the $2-$4 range despite substantial increases in the outstanding
   shares of both companies resulting from the unregistered
   distributions.

   Named as defendants in the action are Technigen and its former
   president Lawrence J. Nesis of Vancouver, British Columbia, Douglas E.
   Mallach of Aurora, Colorado, Sovereign Equity Management Corporation
   of Boca Raton, Florida and its president Glen T. Vittor, and Morton J.
   Glickman of Ontario, Canada.

   The complaint alleges that, while engaged in an illegal distribution
   of unregistered Technigen and TVCN stock, the defendants participated
   in manipulative trading activities including prearranged and matched
   trading and trading through nominee accounts. The complaint further
   alleges that, to further inflate the market price of Technigen and
   TVCN stock, defendants Dambro and Mallach orchestrated a fraudulent
   promotional campaign for the two companies. Among other things, the
   complaint alleges that Dambro, Mallach and Nesis participated in
   preparing and disseminating a brochure which misrepresented
   Technigen's business operations, including purported contracts with
   Sony Corporation. In addition, the complaint alleges that Technigen
   made false and misleading filings with the Commission during the
   fraudulent scheme.

   The complaint, which seeks injunctive relief, disgorgement of proceeds
   raised through the unregistered distributions, and penalties, alleges
   violations by some or all of the defendants of Sections 5(a), 5(c),
   17(a) and 17(b) of the Securities Act of 1933, Sections 10(b), 13(a),
   13(d), and 13(g) of the Securities Exchange Act of 1934, and Rules
   10b-5, 10b-6, 12b-20, 13a-16, 13d-1 and 13d-2 thereunder.
