GARTNERGROUP ADOPTS STOCKHOLDER RIGHTS PLAN

      Wednesday, February 9, 2000 05:38 PM


STAMFORD, Conn.--(BUSINESS WIRE)--February 9, 2000--Gartner Group, Inc. (NYSE:
IT), the world's leading business technology advisor, today announced that its
board of directors has unanimously approved the adoption of a Stockholder Rights
Plan designed to protect GartnerGroup stockholders in the event of an
unsolicited bid for control of the company.

      In connection with this plan, preferred stock purchase rights will be
distributed as a dividend at the rate of one Class A Preferred Share Purchase
Right (a "Class A Right") on each outstanding share of the company's Class A
Common Stock and one Class B Preferred Share Purchase Right (a "Class B Right")
on each outstanding share of the company's Class B Common Stock. Each Right will
entitle the stockholders to buy one share of the company's Series A Junior
Participating Preferred Stock or one share of the company's Series B Junior
Participating Preferred Stock at an exercise price of $90.00 per share.

      Michael D. Fleisher, president and chief executive officer of
GartnerGroup, stated, "This stockholder rights plan was designed to assure that
all GartnerGroup stockholders receive fair and equal treatment in the event of
any proposed takeover of the company and to guard against partial tender offers
and tactics to gain control of GartnerGroup without paying all stockholders the
fair value of their shares."

      Details of the Plan

      The Rights will become exercisable on the eleventh day after a person or
group announces the acquisition of (i) 20 percent or more of the company's Class
A Common Stock; (ii) 20 percent or more of the company's Class B Common Stock;
(iii) 15 percent or more of the aggregate of the Class A Common Stock and the
Class B Common Stock (each item above is considered a "Threshold Amount"); or
(iv) announces commencement of a tender offer, the consummation of which would
result in ownership by the person or group of a Threshold Amount. Certain
exceptions will apply to existing institutional investors currently holding
passive investment positions in excess of the Threshold Amounts.

      If prior to redemption of the Rights, a person or group acquires a
Threshold Amount, each Right owned by stockholders (other than the proposed
acquirer) will entitle its holder to purchase, at the Right's then-current
exercise price, that number of shares of Class A
   2
Common Stock or Class B Common Stock of the company (or as determined by the
board, cash, other property or other securities) having a market value at that
time equal to twice the Right's exercise price. For example, if the stock is
trading at a price of $30.00 per share, the Right will enable the holder to
purchase $180.00 of stock (or 6 shares) for the $90.00 exercise price.
Alternatively, the board of directors may elect to exchange outstanding Rights
held by persons other than the proposed acquirer for Common Stock.

      All GartnerGroup stockholders of record on February 25, 2000, will receive
the dividend distribution of one Class A Right and one Class B Right on each
outstanding share of GartnerGroup's Class A Common Stock or Class B Common
Stock, respectively. All GartnerGroup Class A Common Stock and Class B Common
Stock issued after February 25, 2000, will have Rights attached. The Rights will
expire on February 25, 2010.

      Further details of the Rights are contained in a letter that will be
mailed to all of GartnerGroup's stockholders and will be posted on the company's
Web site at www.gartnerweb.com/investor.
