ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On October 15, 2004, Gartner, Inc. (the "Company") entered into an Employment
Agreement (the "Agreement") with Mr. Eugene A. Hall, with an effective date of
August 1, 2004, pursuant to which Mr. Hall will serve as Chief Executive Officer
and a director of the Company.

The Agreement has an initial term of three years, with automatic one year
renewals commencing on the third anniversary, unless either party provides the
other with at least 90 days prior written notice that the term shall not be
extended. Under the Agreement, Mr. Hall's annual base salary initially is
$650,000 and he will be eligible to receive a bonus upon the achievement of
certain performance objectives. The annual target bonus shall be equal to 100%
of Mr. Hall's annual base salary, with the actual bonus being subject to
adjustment for over- or under-achievement of Company and individual objectives,
provided, however, that the maximum actual bonus will not exceed 200% of Mr.
Hall's base salary. The bonus for the first (12) months of Mr. Hall's employment
will be guaranteed at 100% of Mr. Hall's base salary.

The Agreement further provides that Mr. Hall will receive a nonqualifed stock
option to purchase an aggregate of 800,000 shares of Class A Common Stock of the
Company, with a per-share exercise price equal to the per-share fair market
value of Class A Common Stock of the Company on the date of grant. The option
shall vest in equal annual installments on the first four anniversaries of the
date of grant, subject to Mr. Hall's continued employment with the Company on
each vesting date. Notwithstanding the preceding sentence, the option shall vest
in full upon a change in control.

The Agreement also provides that Mr. Hall will be granted 500,000 restricted
shares of Class A Common Stock of the Company, with a par value purchase price.
Restrictions shall lapse as to (i) 300,000 shares when the Company's Class A
Common Stock trades at an average price of $20 or more for sixty (60)
consecutive trading days, (ii) 100,000 shares when the Company's Class A Common
Stock trades at an average price of $25 or more for sixty (60) consecutive
trading days, and (iii) 100,000 shares when the Company's Class A Common Stock
trades at an average price of $30 or more for sixty (60) consecutive trading
days, subject to Mr. Hall's continued employment with the Company through each
such date. Notwithstanding the preceding sentence, all restrictions shall lapse
in full upon a change in control.

Pursuant to the Agreement, Mr. Hall is also entitled to receive all benefits
provided to senior executives, executives and employees of the Company generally
from time to time, including medical, dental, life insurance and long-term
disability, in each case so long as and to the extent the same exist.

Pursuant to the Agreement, if the Company terminates the employment of Mr. Hall
involuntarily and without business reasons or a constructive termination occurs,
or if the Company elects not to renew the Agreement upon the expiration of the
employment term and Mr. Hall within ninety (90) days following the expiration of
the employment term terminates his employment, then, subject to Mr. Hall signing
and not revoking a general release of claims against the Company and its
successors, Mr. Hall shall be entitled to receive the following: (i) base salary
and paid time off ("PTO") accrued through the termination date plus continued
base salary for a period of twenty-four months following the termination date,
payable in accordance with the Company's regular payroll schedule as in effect
from time to time, (ii) at the termination date, 200% of Mr. Hall's target bonus
for the fiscal year in which the termination date occurs, and any earned but
unpaid bonus from the prior fiscal year, (iii) 24 months' continued vesting
under all outstanding stock options and other equity arrangements subject to
vesting and held by Mr. Hall (with a post-termination exercise period of
approximately 24 months, subject to the maximum term of the award), and (iv)
reimbursement for premiums incurred to continue group health benefits (or, at
the Company's election, to obtain substantially similar health benefits through
a third party carrier) for twenty-four (24) months for Mr. Hall, his spouse and
any children, provided that Mr. Hall makes the appropriate election.

In the event of a change in control, Mr. Hall shall be entitled to receive the
following: (i) base salary and PTO accrued through the date of the change in
control plus an amount equal to three (3) years of Mr. Hall's base salary as
then in effect, (ii) an amount equal to three (3) times Mr. Hall's target bonus
for the fiscal year in which the change in control occurs, and (iii) (a) for at
least three (3) years following the date of the change in control (even if Mr.
Hall ceases employment), continuation of group health benefits at the Company's
cost pursuant to the Company's


standard programs as in effect from time to time (or at the Company's election
substantially similar health benefits as in effect at the termination date (if
applicable), through a third party carrier) for Mr. Hall, his spouse and any
children, and (b) thereafter, to the extent COBRA shall be applicable,
continuation of health benefits for such persons at Mr. Hall's cost, for a
period of 18 months or such longer period as may be applicable under the
Company's policies then in effect, provided that Mr. Hall makes the appropriate
election and payments.

Pursuant to the Agreement, Mr. Hall will also receive additional payments equal
to any excise tax and related income tax incurred as a result of any payments
made by the Company that would not have been imposed absent such payments
(including excise taxes on change in control payments made to Mr. Hall)
sufficient to restore him to the same after-tax position he would have been in
if the excise tax had not been imposed.

The Employment Agreement between the Company and Mr. Hall is attached hereto as
Exhibit 10.1 and incorporated herein by reference.

On October 15, 2004, the Company also entered into a Restricted Stock Agreement
with Mr. Hall, the material terms of which are included in the description
above.

The Restricted Stock Agreement between the Company and Mr. Hall is attached
hereto as Exhibit 10.2 and incorporated herein by reference.
