ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS.

         On November 15, 1999, pursuant to a Stock Purchase Agreement (the
"Stock Purchase Agreement") among Forrester Research, Inc. ("Forrester"), Neil
Bradford and William Reeve, Forrester acquired all of the outstanding capital
stock of Fletcher Research Limited ("Fletcher"), an Internet research company
located in the United Kingdom. The aggregate purchase price paid by Forrester
under the Stock Purchase Agreement consisted of approximately $19 million in
Forrester's common stock, valued at its average trading price on the Nasdaq
National Market for the 30 trading days ending on November 13, 1999. It is
expected that the transaction will be accounted for as a pooling of interests.
Forrester estimates that it will incur a one-time charge in the fourth-quarter
ranging from $500,000 to $700,000 for costs related to this transaction. In
connection with the acquisition, Forrester agreed to register 25% of the common
stock, or approximately 100,400 shares, paid to Messrs. Bradford and Reeve as
part of the purchase price for Fletcher.

         The foregoing description is qualified in its entirety by reference to
the Stock Purchase Agreement, as copy of which is attained hereto as Exhibit 2.1
and incorporated herein by reference.

ITEM 7.           FINANCIAL STATEMENTS AND EXHIBITS.
