U.S. SECURITIES AND EXCHANGE COMMISSION



          Litigation Release No.   15994 / December 7, 1998

          Securities and Exchange Commission v. Hahn Truong, Hieu Truong,
          Hen Truong, Nina Vinh, Mike Pirbazari and Christopher Nguyen,
          Civil Action No. C-98-21137 SW (N.D. Cal.)

               The Securities and Exchange Commission ("Commission")
          announced that on November 30, 1998, the Honorable Spencer
          Williams, Senior United States District Judge, entered a final
          judgment against Mike Pirbazari ("Pirbazari") permanently
          enjoining him from violating the antifraud provisions of the
          federal securities laws.  The final judgment also sets
          disgorgement of Pirbazari's ill-gotten gains, plus prejudgment
          interest, at $6,194.62 and imposes a civil penalty of $5,125.00.

               The Commission's complaint, filed on November 16, 1998,
          alleges that Hahn Truong used confidential corporate information
          in selling shares in his then-employer, Molecular Dynamics, Inc.
          ("Molecular"), and tipped his brothers Hieu Truong ("Hieu") and
          Hen Truong, and his friend Christopher Nguyen, each of whom sold
          all of his Molecular shares and sold short additional Molecular
          shares.  The Commission's complaint further alleges that Hieu in
          turn tipped his sister-in-law, Nina Vinh ("Nina"), who sold all
          of her Molecular shares, sold short additional Molecular shares
          and tipped her sister and her friend, Pirbazari, each of whom
          sold all of her/his Molecular shares.  The defendants and Nina's
          sister avoided losses totaling $294,151 and made short selling
          profits of $134,985.

               The final judgment enjoins Pirbazari from future violations
          of Section 17(a) of the Securities Act of 1933 and Section 10(b)
          of the Securities Exchange Act of 1934 and
          Rule 10b-5 thereunder.  Pirbazari consented to the entry of the
          final judgment without admitting or denying the Commission's
          allegations.
