            "Amendment"), in respect of the Credit Agreement dated as of July
            16, 1999, as amended and restated as of July 17, 2000, as further
            amended by Amendment No. 3 dated as of May 30, 2002 (as heretofore
            amended, the "Credit Agreement" and, as amended by this Amendment,
            the "Amended Credit Agreement"), among Gartner, Inc. (the
            "Borrower"), the Lenders party thereto and JPMorgan Chase Bank, as
            Administrative Agent (in such capacity, the "Administrative Agent").

      The Borrower has requested that the Credit Agreement be amended to effect
the amendment set forth below, and the parties hereto are willing so to amend
the Credit Agreement. Each capitalized term used but not defined herein has the
meaning assigned thereto in the Amended Credit Agreement.

      In consideration of the premises and the agreements, provisions and
covenants herein contained, the parties hereto hereby agree, on the terms and
subject to the conditions set forth herein, as follows:

      SECTION 1. Amendment. Upon the effectiveness of this Amendment as provided
in Section 3 below, the Credit Agreement shall be amended as follows:

      (a) Section 6.08 of the Credit Agreement is hereby amended by replacing
the phrase "after May 29, 2002 does not exceed $50 million" in clause (vii)
therein with the phrase "after March 31, 2003 does not exceed $50 million".

      SECTION 2. Representations and Warranties. The Borrower represents and
warrants as of the date hereof to each of the Lenders that:

      (a) Before and after giving effect to this Amendment, the representations
and warranties set forth in the Credit Agreement and the other Loan Documents
are true and correct in all material respects with the same effect as if made on
the date hereof, except to the extent such representations and warranties
expressly relate to an earlier date.

      (b) Immediately before and after giving effect to this Amendment, no Event
of Default or Default has occurred and is continuing.

      SECTION 3. Conditions to Effectiveness. The amendment set forth in Section
1 of this Amendment shall become effective, as of the date hereof, on the date
(the "Amendment Closing Date") on which the Administrative Agent shall have
received (a) counterparts of this Amendment that, when taken together, bear the
signatures of the Borrower, the Administrative Agent, the Subsidiary Loan
Parties and the Required Lenders, (b) an amendment fee, for distribution to each
Lender that has returned a signed counterpart of this Amendment to the
Administrative Agent or its counsel by 5:00 p.m. New York City time on March 31,
2003, equal to 0.125% of the aggregate Commitments of each such signing Lender
and (c) payment of all fees and expenses (to the extent invoiced prior to the
Amendment Closing Date) payable to JPMorgan Chase Bank and J.P. Morgan
Securities Inc. in connection with this Amendment. The provisions of Section 1
shall terminate and cease to be of any force or effect if the Amendment Closing
Date shall not have occurred on or prior to March 31, 2003.

      SECTION 4. Agreement. Except as specifically stated herein, the provisions
of the Credit Agreement are and shall remain in full force and effect. As used
therein, the terms "Credit Agreement", "herein", "hereunder", "hereinafter",
"hereto", "hereof" and words of similar import shall, unless the context
otherwise requires, refer to the Amended Credit Agreement. The Subsidiary Loan
Parties are executing this Amendment to confirm that their obligations under the
Guarantee Agreement, the Pledge Agreement and the Indemnity, Subrogation and
Contribution Agreement remain in full force and effect with respect to the
Amended Credit Agreement and all references in the Guarantee Agreement, the
Pledge Agreement and the Indemnity, Subrogation and Contribution Agreement to
the Credit Agreement shall hereafter be deemed to refer to the Amended Credit
Agreement.

      SECTION 5. Applicable Law. THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

      SECTION 6. Counterparts. This Amendment may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract.

      SECTION 7. Expenses. The Borrower agrees to reimburse the Administrative
Agent for all reasonable out-of-pocket expenses incurred by it in connection
with this Amendment, including the reasonable fees, charges and disbursements of
Cravath, Swaine & Moore, counsel for the Administrative Agent.

      IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
duly executed by their respective authorized officers as of the day and year
first written above.
