                   (With Independent Auditors' Report Thereon)



                          INDEPENDENT AUDITORS' REPORT

To the Participants and Administrative Committee of the
Gartner, Inc. Savings and Investment Plan:

We have audited the accompanying statements of net assets available for benefits
of the Gartner, Inc. Savings and Investment Plan (the Plan) as of December 31,
2002 and 2001, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2002. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
the significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2002 and 2001 and the changes in the net assets available for
benefits for the year ended December 31, 2002 in conformity with accounting
principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule H, Line 4i-
schedule of assets (held at end of year) as of December 31, 2002 is presented
for the purpose of additional analysis and is not a required part of the basic
financial statements but is supplementary information required by the Department
of Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This supplemental schedule is the
responsibility of Plan's management. The supplemental schedule has been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, is fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                          Notes to Financial Statements
                           December 31, 2002 and 2001

(1)    DESCRIPTION OF THE PLAN

       The following description of the Gartner, Inc. Savings and Investment
       Plan (the Plan) provides only general information. Participants should
       refer to the plan agreement for a more complete description of the Plan
       provisions.

       (a)    GENERAL

              The Plan is a defined contribution retirement plan subject to the
              provisions of the Employee Retirement Income Security Act of 1974
              (ERISA). The Plan has been amended and restated at various times
              in order to comply with regulatory guidance, most recently as of
              April 9, 2003 (see note 4).

              The Plan covers substantially all domestic full-time employees of
              Gartner, Inc. and its wholly owned subsidiaries (collectively the
              Company or Employer). Any employee who customarily works at least
              20 hours per week (minimum of 1,000 hours per year) and is at
              least 18 years of age is eligible to participate in the Plan.

       (b)    ADMINISTRATION

              The Plan is administered by the Administrative Committee (the Plan
              Committee) which is appointed by the Company's Board of Directors.
              The Plan Committee is responsible for all administrative aspects
              of the Plan, including selection of trustees and investment
              managers, establishment of investment alternatives, determination
              of benefit eligibility and benefit calculations and interpretation
              of Plan provisions. The Plan Committee has appointed officers of
              the Company to act as trustees (the Trustees) to administer the
              Plan. Administrative expenses are to be paid by the Plan through
              the use of participant forfeitures. Any administrative expenses in
              excess of participant forfeitures will be paid by the Company. For
              the plan year ended December 31, 2002 all expenses were paid by
              the Plan.

       (c)    CONTRIBUTIONS

              Participating employees may make annual contributions to the Plan
              in percentages of not less than 1% or more than 60% of total
              annual compensation (50% pre-tax, 10% post-tax), as defined in the
              Plan agreement, subject to Internal Revenue Service (IRS)
              limitations. Participants who are eligible may make pre-tax
              Catch-Up Contributions effective January 1, 2002 subject to the
              IRS limitations.

              For 2002, the Plan requires the Company to match 100% of pre-tax
              participant contributions up to a maximum of 4% of a participant's
              total compensation, or $4,400, which is 40% of the IRS pre-tax
              contribution limitation for 2002.

              The Plan also provides for a profit sharing contribution comprised
              of the following elements:

              -      Fixed amount - an amount equal to 1% of a participant's
                     base compensation, subject to an IRS limitation.

                                       4



              -      Discretionary amount - an amount in excess of the fixed
                     amount solely at the discretion of the Company's Board of
                     Directors based on the financial results of the Company.

              Fixed profit sharing contributions of $1,999,371 and $2,073,272
              for the years ended December 31, 2002 and 2001, respectively, have
              been presented as employer contributions receivable in the Plan
              financial statements as of December 31, 2002 and 2001,
              respectively. There were no discretionary contributions made to
              the Plan for the Plan years ended December 31, 2002 and 2001.

              A participant may make "after tax" contributions of up to 10% of
              the participants compensation, subject to a maximum of $20,000
              per year in 2002.

       (d)    PARTICIPANTS ACCOUNTS

              Separate accounts are maintained for each participant of the Plan
              through the Fidelity Management Trust Company (Fidelity). The
              participants' accounts are adjusted to reflect contributions and
              investment earnings such as interest, dividends, and realized and
              unrealized investment gains and losses.

              At December 31, 2002 and 2001, forfeited nonvested accounts
              totaled $38,575 and $64,642, respectively. These accounts will be
              used to pay Plan expenses and reduce future employer
              contributions. Also, in 2002, employer contributions were reduced
              by $100,000 and plan expenses of $81,334 were paid from forfeited
              nonvested accounts.

       (e)    INVESTMENTS

              Participants may elect to invest in a variety of specialized
              investment funds and may make transfers among investment funds at
              their discretion in whole percentages. The Company's Board of
              Directors has authorized Fidelity to execute transactions upon
              direction from the participant within the framework of the trust
              instrument.

       (f)    VESTING

              Participants are immediately vested in their own contributions and
              in the Employer's matching contributions. Participants vest in the
              profit sharing contributions ratably over a five-year period based
              on date of hire. The date of hire for the employees of acquired
              companies continues to be their historical date of hire by the
              acquired company for vesting purposes.

       (g)    LOANS TO PARTICIPANTS

              Loans to participants are permitted, with the Trustees' consent,
              in accordance with the limits provided by the Internal Revenue
              Code. Loans bear interest at a rate equal to prime plus 1% which
              ranged between 5.25% and 6.0% for loans made during the year ended
              December 31, 2002, and 5.75% and 10.5% for loans made during the
              year ended December 31, 2001. Participants receiving loans from
              the Plan must execute an interest bearing promissory note in the
              amount of the loan. The terms of the promissory note require that
              all participants repay their loans based upon a fixed repayment
              schedule not to exceed a five-year period, except in the case of a
              primary residence loan for which the repayment period is extended
              to 15 years. Participant loans are subject to a $1,000 minimum
              amount and limited to 50% of a Participant's vested account
              balance, not to exceed $50,000.

                                       5



       (h)    PAYMENT OF BENEFITS

              Benefits are paid upon retirement (on or after age 55), death or
              termination of employment, and may also be distributed prior to
              termination of employment upon reaching age 59-1/2 or because of
              financial hardship. Participants' benefits are paid in a lump sum
              equal to the vested value of the Participant's account at the time
              of payment. With respect to accounts from the former Pension Plan
              that was merged into this Plan in 1993, an annuity (joint and 50%
              survivor for married Participants and single life for unmarried
              Participants) is the standard form of payment. With respect to
              such Pension Plan accounts, Participants may elect a lump sum
              payment instead of the annuity, with spousal consent as
              applicable.

       (i)    PLAN TERMINATION

              Although it has not expressed any intent to do so, the Company
              reserves the right to fully or partially terminate the Plan at any
              time by action of the Board of Directors or its designee. In such
              an event, all participants will become fully vested in their
              account balance as of the date of full or partial termination.

(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       (a)    BASIS OF ACCOUNTING

              The financial statements have been prepared using the accrual
              basis of accounting.

       (b)    VALUATION OF INVESTMENTS

              The Plan's investments are valued at fair value based upon market
              prices quoted on national stock exchanges for the respective
              funds. Shares of registered company investments are valued at the
              net asset value of shares held by the Plan at year end.

       (c)    USE OF ESTIMATES

              The preparation of financial statements in conformity with
              accounting principles generally accepted in the United States of
              America requires management to make significant estimates and
              assumptions that affect the reported amounts of assets and
              liabilities, the disclosures of contingent assets and liabilities
              at the date of the financial statements, and the reported amounts
              of additions to and deductions from net assets during the
              reporting period. Actual results could differ from those
              estimates.

       (d)    RISKS AND UNCERTAINTIES

              The Plan provides for various investment options. Investment
              securities are exposed to various risks such as interest rate,
              market and credit. Due to the risk associated with investment
              securities and the uncertainty related to changes in the value of
              such securities, it is at least reasonably possible that changes
              in risks in the near term could materially affect participant's
              account balances and the amounts reported in the statements of net
              assets available for plan benefits and the statements of changes
              in net assets available for plan benefits.

       (e)    INVESTMENT TRANSACTIONS AND RELATED INCOME

              Purchases and sales of interests in the investment funds, along
              with realized gains and losses, are accounted for on the trade
              date.

                                       6



              Dividends represent the Plan's share in dividend income of the
              investment funds in which the Plan participates. Dividends are
              recorded on the ex-dividend date. Income from other investments is
              recorded as earned on an accrual basis.

(3)    INVESTMENTS

       Substantially all of the Plan's assets are invested in mutual funds and a
       commingled investment fund managed by Fidelity. A brief description of
       the funds and investments is as follows:

       (a)    GARTNER, INC. STOCK FUND

              The assets of this fund are substantially invested in Gartner,
              Inc. Class A Common Stock. This Fund also maintains
              interest-bearing cash, $153,024 and $220,674 at December 31, 2002
              and 2001, respectively, to meet liquidity needs from participant
              withdrawals or transfers.

       (b)    FIDELITY RETIREMENT MONEY MARKET FUND

              Investments are held in a diversified portfolio of domestic and
              international short term fixed income securities such as corporate
              commercial paper, certificates of deposit, Treasury notes and
              bills and bankers acceptances.

       (c)    OTHER FUNDS

              The Magellan, Growth Company, OTC Portfolio and Overseas Funds
              invest in debt and equity securities of companies of varying sizes
              with above average growth potential to achieve long-term capital
              appreciation. The US Equity Index Fund seeks to match the total
              return of the Standard & Poor 500 Index. The Puritan, Equity
              Income and Intermediate Bond Funds seek current income and capital
              preservation as well as the potential for capital appreciation by
              investing in a diversified portfolio of common and preferred
              stocks and bonds. The Fidelity Freedom Funds are asset allocation
              funds that invest in other Fidelity mutual funds; there are five
              funds that are managed to specific target retirement dates - 2000,
              2010, 2020, 2030, and 2040 and a sixth fund, the Fidelity Freedom
              Income Fund, for those actively seeking high current income. The
              Fidelity Select Portfolios are mutual funds that invest in
              specific sectors or industries. Investors are able to obtain
              targeted diversification with industry specific mutual funds and
              an opportunity to invest in industries with high growth potential.

              The market value of investments exceeding 5% of Plan assets as of
              December 31, 2002 and 2001 are summarized as follows:



                                                     2002            2001
                                                  -----------     -----------
                                                            
Investments at fair value was determined by
  quoted market prices:
    Fidelity Retirement Money Market Fund         $18,275,416      17,006,407
    Fidelity Magellan Fund                         25,638,106      33,392,044

    Fidelity Equity Income Fund                    14,288,436      17,078,303
    Fidelity OTC Portfolio Fund                     7,599,065       9,403,824
    Fidelity Intermediate Bond Fund                 9,088,626       5,277,503


                                       7



              During 2002 the Plan's investments (including investments bought,
              sold, and held during the year) depreciated in value by
              $30,899,903 as follows:

                                         ============


(4)    PLAN TAX STATUS

       On February 28, 2002, the plan requested a favorable determination letter
       as to the continuing qualification of the Plan under IRC Section 401(a).
       This request included a request for review of the provisions required by
       the Uruguay Round Agreements Act (GATT), the Uniformed Services
       Employment and Reemployment Rights Act of 1994, the Small Business Job
       Protection Act of 1996, the Taxpayer Relief Act of 1997, the Internal
       Revenue Service Restructuring and Reform Act of 1998, and the Community
       Renewal Tax Relief Act of 2000 (collectively referred to as GUST). The
       Internal Revenue Service has determined and informed the Company by
       letter dated April 7, 2003, that the Plan and related trust, including
       the proposed amendments, which were subsequently adopted by the Plan on
       April 9, 2003, are designed in accordance with the applicable sections of
       the Internal Revenue Code (Code). Gartner, Inc. believes that the Plan
       currently is designed and being operated in compliance with the
       applicable requirements of the Code and that, therefore, the Plan
       qualifies under Section 401(a) and the related trust is tax-exempt as of
       December 31, 2002. Therefore, no provision for income taxes has been
       included in the Plan's financial statements.

(5)    RELATED PARTY TRANSACTIONS

       Certain Plan investments are shares of mutual funds managed by Fidelity
       Management & Research Company, an affiliate of Fidelity Management Trust
       Company, the Trustee as defined by the Plan, and therefore, these
       transactions qualify as party-in-interest. Another investment is an
       investment fund comprised primarily of shares of common stock issued by
       Gartner, Inc. Gartner, Inc. is the Plan sponsor as defined by the Plan.
