Item 2:     Changes in Securities and Use of Proceeds

        (c) As disclosed in the Report on Form 10-Q filed by HNC Software Inc.
("HNC") for its fiscal quarter ended March 31, 1998, on March 31, 1998 HNC
issued 142,862 shares of its common stock (after elimination of fractional
shares) as consideration for HNC's acquisition of Practical Control Systems
Technologies, Inc. ("PCS"), a distribution center management software vendor
based in Cincinnati, Ohio. These shares were issued by HNC in a merger
transaction in which PCS became a wholly-owned subsidiary of HNC. Of the 142,862
shares of common stock issued to the former PCS shareholders, 14,286 shares
owned by the largest former shareholder of PCS are subject to an escrow to
secure certain indemnification obligations of such shareholder to HNC. The PCS
shareholders also have the contingent right, subject to PCS' achievement of
certain financial objectives during calendar 1998 and 1999, to receive
additional shares of HNC common stock based on a formula. The shares issued by
HNC in this transaction were offered and sold solely to the shareholders of PCS
in exchange for the transfer of their entire ownership interests in PCS in the
merger. The shares of HNC common stock issued in the PCS merger were issued
without registration under the Securities Act of 1933, as amended (the "1933
Act") in reliance on the exemptions afforded by Section 4(2) of the 1933 Act and
Rule 506 of Regulation D promulgated under the 1933 Act. In relying upon the
foregoing exemptions, HNC took into account the limited number of PCS's
shareholders (13 in total), the limitation of HNC's offering to such
shareholders, the information regarding PCS , HNC and the merger furnished to
such shareholders, the representation of PCS and certain of its shareholders by
legal counsel in connection with the transaction and representations and
warranties made by PCS and the PCS shareholders to HNC in connection with the
transaction.
