ITEM 5   OTHER EVENTS

         On June 13, 1999, Abacus Direct Corporation, a Delaware corporation
("Abacus") entered into an Agreement and Plan of Merger and Reorganization (the
"Merger Agreement") with DoubleClick, Inc., a Delaware corporation
("DoubleClick"), pursuant to which DoubleClick has agreed to acquire Abacus. A
copy of the Merger Agreement is attached hereto as Exhibit 2.1 and incorporated
herein by reference. The acquisition is to be effected through the issuance of
1.05 shares of DoubleClick common stock in exchange for each share of common
stock of Abacus outstanding immediately prior to the consummation of the
transaction and the assumption of Abacus' stock options outstanding at the
effective date of the merger, based on such exchange ratio. Upon consummation of
the transaction the stockholders of Abacus will own approximately 20.5% of the
issued and outstanding common stock of DoubleClick. The amount of such
consideration was determined based upon arm's-length negotiations between
DoubleClick and Abacus. The Merger Agreement also provides for the payment by
Abacus to DoubleClick under certain circumstances of a fee (the "Termination
Fee") of $30 million plus a maximum of $2.5 million in DoubleClick expenses in
the event the Merger Agreement is terminated. The transaction is intended to
qualify as a tax-free reorganization under the Internal Revenue Code of 1986, as
amended, and is intended to be accounted for as a pooling of interests. The
consummation of the transaction is subject to the satisfaction of certain
conditions, including certain regulatory approvals and the approval of the
stockholders of Abacus and DoubleClick.

         In connection with the transaction, DoubleClick and Abacus also entered
into a Stock Option Agreement on June 13, 1999, pursuant to which Abacus has
granted to DoubleClick an option to purchase up to 1,974,516 newly-issued shares
of Abacus common stock under certain circumstances similar to those requiring
the payment of the Termination Fee. A copy of the Stock Option Agreement is
attached hereto as Exhibit 10.1 and incorporated herein by reference. In
addition, certain affiliates of Abacus have agreed to vote in favor of approval
of the Merger Agreement.

         Certain of the matters discussed herein include forward-looking
statements within the meaning of  Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Statements that are
predictive in nature, that depend upon or refer to future events or conditions,
or that include words such as "experts", "anticipates", "intends", "plans",
"believes", "estimates" and similar expressions are forward-looking statements.
The actions of current and potential new competitors, changes in technology,
seasonality, business cycles, new regulatory requirements, general economic and
market conditions and other uncertainties and events outside Abacus' control may
cause Abacus' actual results to differ from the expectations expressed in such
forward-looking statements.
