Item 2.   Acquisition or Disposition of Assets.

     On March 11, 1999 (the "Effective Date"), SS&C Technologies, Inc. (the
"Company") completed its acquisition of HedgeWare, Inc. ("HedgeWare") pursuant
to an Agreement and Plan of Merger, dated as of March 11, 1999 (the "Merger
Agreement"), among the Company, HedgeWare, Asset Management Acquisition Corp., a
wholly owned subsidiary of the Company (the "Merger Subsidiary"), Michael J.
Lazarcheck, Robert H. Pontbriand and Matthew J. Cosciello (collectively the
"Stockholders") and Andrew Appell, Eugene Barra, Ellis Horowitz, Ronald Kashden,
Brook F. Seitz, Mark E. Tarantina and Alan Zenreich (collectively the
"Performance Unit Holders").  The Stockholders and Performance Unit Holders are
referred to collectively herein as the "Holders."

     Pursuant to the Merger Agreement, the Merger Subsidiary was merged with and
into HedgeWare (the "Merger") on the Effective Date, whereupon HedgeWare became
a wholly owned subsidiary of the Company. In connection with the Merger, (i) all
of the outstanding shares of common stock of HedgeWare held by the Stockholders
were converted into an aggregate of 499,718 shares of Common Stock of the
Company (the "Common Stock"), (ii) all of the outstanding performance units
under HedgeWare's Performance Unit Plan held by the Performance Unit Holders
were converted into an aggregate of 124,930 shares of Common Stock and (iii)
outstanding loans, interest and dividends aggregating approximately $1,000,000
and owed by HedgeWare to the Stockholders were converted into an aggregate of
61,035 shares of Common Stock. The Company used authorized but previously
unissued shares of Common Stock in connection with the Merger, which will be
accounted for as a pooling of interests.

     The Company, HedgeWare and the Holders have entered into an Escrow
Agreement providing, among other things, that 89,139 shares of Common Stock
received by the Holders in the Merger will be held in escrow to reimburse the
Company in connection with the breaches of representations, warranties or
covenants made by HedgeWare and the Holders in the Merger Agreement, as well as
potential rental obligations and sales tax liabilities of HedgeWare.

     The Company has agreed, upon the written request of the holders of a
majority of the shares of Common Stock issued in connection with the Merger at
any time prior to March 11, 2000 (subject to certain limitations), to file a
registration statement on Form S-3 covering the resale to the public of such
shares of Common Stock.

     Prior to the Merger, HedgeWare engaged in the development and marketing of
portfolio, financial partnership and tax accounting software and service support
to hedge fund managers and traders.  The Company currently intends to continue
HedgeWare's business substantially in the manner conducted by HedgeWare
immediately prior to the Merger.

     The Merger Agreement and the Merger were approved by the Board of Directors
of the Company and the Board of Directors and stockholders of HedgeWare.  The
terms of the Merger Agreement and the Merger were determined on the basis of
arm's-length negotiations.  Prior to the execution of the Merger Agreement,
neither the Company nor any of its affiliates, nor any director or officer of
the Company nor any associate of any such director or officer, had any material
relationship with HedgeWare or any of the Holders.

     The foregoing description of the Merger Agreement does not purport to be
complete and is qualified in its entirety by reference to the full text of the
Merger Agreement, which is filed as Exhibit 2 to this Current Report on Form 8-K
and incorporated herein by reference.  The Company's press release dated March
11, 1999, which is filed as Exhibit 99 to this Current Report on Form 8-K, is
also incorporated herein by reference.
