ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.
- ----------------------------------------------

     On April 9, 1998, CMG Information Services, Inc. (the "Company"), a
Delaware corporation, acquired all the issued and outstanding shares of capital
stock of Accipiter, Inc. ("Accipiter"), a Delaware corporation, pursuant to a
merger of CMGI Acquisition Corporation, a Delaware corporation and wholly-owned
subsidiary of the Company, with and into Accipiter (the "Merger"), with
Accipiter becoming the surviving corporation and a wholly-owned subsidiary of
the Company. Accipiter is a Raleigh, North Carolina-based company specializing
in the development of software tools for the management of advertising over the
Internet. The acquisition was consummated pursuant to an Agreement and Plan of
Merger (the "Merger Agreement") dated April 8, 1998 among the Company, CMGI
Acquisition Corporation, Accipiter and certain stockholders of Accipiter. The
Company expects to ultimately merge Accipiter with the Company's subsidiary,
Engage Technologies, Inc.

     The acquisition will be accounted for as a purchase.  The purchase price
will be allocated to the assets acquired and liabilities assumed based on their
estimated fair values.  Results of operations for Accipiter will be included in
the Company's consolidated operating results for periods subsequent to the date
of acquisition.

     In the Merger, all outstanding shares of Common Stock and Preferred Stock
of Accipiter and vested rights to purchase Common Stock and Preferred Stock of
Accipiter were converted into approximately 632,000 shares of Common Stock, par
value $0.01 per share, of the Company (the "CMG Shares"). All unvested rights to
purchase Common Stock and Preferred Stock of Accipiter have been cancelled after
the Merger or provided for under the terms of the two escrow agreements
described below.

     The CMG Shares are not registered under the Securities Act of 1933 and are
subject to either Non-Employee Investment Representation and Lockup Letters or
Employee Investment Representation and Lockup Letters (together, the "Lockup
Agreements").  The Lockup Agreements prohibit transfer of the CMG Shares,
without the permission of the Company, for periods ranging from six to twenty-
four months.  The holders of the CMG Shares are entitled to two required
registrations under Form S-3 after six and twelve months from the date of the
Merger Agreement, as well as certain other registration rights, with respect to
CMG Shares no longer subject to the Lockup Agreements.

     Under the terms of the Merger Agreement and related Non-Employee and
Employee Stockholder Escrow Agreements, an aggregate of 91,655 of the CMG Shares
will be held in escrow for the purpose of indemnifying the Company against
certain liabilities of Accipiter and its stockholders.  Additionally, the
Employee Stockholder Escrow Agreement provides for the forfeiture to the Company
of a portion of the CMG Shares in the event that Accipiter does not meet certain
performance targets.  The Employee Stockholder Escrow Agreement and Non-Employee
Stockholder Escrow Agreement expire twelve and twenty-four months after April 8,
1998, respectively.
