       Naples, Florida and Phoenix, Arizona -- June 5, 2000--Allen Systems
Group, Inc., ASG Sub, Inc. and Viasoft, Inc. (Nasdaq NM: VIAS) today announced
the preliminary results of their cash tender offer for all of the outstanding
shares of common stock of Viasoft at the offer price of $8.40 per share.

        The offer and withdrawal rights expired, as scheduled, at 12:00
midnight, Eastern time, on Friday, June 2, 2000. Based on the preliminary report
of Equiserve, the depositary for the offer, approximately 16,926,908 Viasoft
shares were validly tendered and not withdrawn (including approximately 788,100
shares subject to guarantee of delivery), representing approximately 93% of
Viasoft's outstanding shares. ASG Sub, Inc. and Viasoft, Inc. have accepted
these shares for payment (excluding shares subject to guarantee of delivery,
which shall be accepted and paid for upon completion of delivery). Payment for
shares properly tendered and accepted will be made as promptly as practical and,
in the case of shares tendered by guaranteed delivery procedures, promptly after
delivery of the shares and required documentation.

        Allen Systems intends to acquire the remaining shares of Viasoft. Allen
Systems intends to cause ASG Sub to be merged into Viasoft, pursuant to which
each share of Viasoft's common stock still outstanding, other than those held by
ASG Sub, will be converted into the right to receive $8.40 in cash, the same
consideration paid for shares in the tender offer, subject to appraisal rights.
After the merger, Viasoft will be a wholly-owned subsidiary of Allen Systems
