EXECUTION COPY

STOCK PURCHASE AGREEMENT

     This Stock Purchase Agreement (the “Agreement”) is made as of September 15, 2006 by and among ValueAct Capital Master Fund III, L.P., a limited partnership organized under the laws of the British Virgin Islands (the “Purchaser”), Silver Lake Partners, L.P., a Delaware limited partnership, Silver Lake Investors, L.P., a Delaware limited partnership, and Silver Lake Technology Investors, L.L.C., a Delaware limited liability company (collectively, “Silver Lake”).

R E C I T A L S

     A. WHEREAS, as of the date hereof, Silver Lake owns of record 25,615,128 shares of common stock, par value $0.0005 per share (the “Common Stock”), of Gartner Inc. (the “Company”), which constitutes approximately 22.5% of the issued and outstanding shares of Common Stock of the Company;

     B. WHEREAS, ValueAct Capital Master Fund, L.P. which is an affiliate of the Purchaser, owns of record 18,631,646 shares of Common Stock, which constitutes approximately 16.3% of the issued and outstanding shares of common stock of the Company.

     C. WHEREAS, VA Partners III, L.L.C. (“VA Partners”) is the General Partner of the Purchaser, and Jeffrey W. Ubben, a director of the Company, is a Managing Member, principal owner and controlling person of VA Partners.

     D. WHEREAS, Silver Lake desires and voluntarily agrees to sell certain shares of Common Stock held by Silver Lake to the Purchaser, and the Purchaser desires to purchase such shares from Silver Lake.

     E. WHEREAS, the parties understand that shortly after the consummation of the transactions contemplated by this agreement the Company shall cause a registration statement to be filed to register the Shares (as defined below) for resale pursuant to the Securities Act of 1933 (the “Offering”); and

     F. WHEREAS, the Purchaser and Silver Lake desire to make certain covenants and agreements with one another pursuant to this Agreement.

     NOW THEREFORE, in consideration of the covenants and promises set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

     1. Purchase and Sale of the Shares; the Closing.

          1.1 Purchase and Sale of Common Stock. Subject to the terms and conditions of this Agreement, and on the basis of the representations, warranties and covenants set forth herein, Silver Lake agrees to sell to the Purchaser, and the Purchaser agrees to purchase from Silver Lake, 2,000,000 shares of Common Stock (the “Shares”). The allocation of the Shares to be sold by each Silver Lake entity at the

Closing shall be pro rata based on the number of shares of Common Stock held of record by each of Silver Lake Partners, L.P., Silver Lake Investors, L.P., and Silver Lake Technology Investors, L.L.C., rounded to the nearest whole share, or in such other proportion as Silver Lake may determine.

          1.2 Purchase Price. The “Per Share Purchase Price” for the Shares shall be equal to $15.75 per share. The “Purchase Price” shall equal the Per Share Purchase Price specified in this Section 1.2 multiplied by the number of Shares purchased by each Purchaser from Silver Lake pursuant to Section 1.1 of this Agreement.

          1.3 The Closing. Subject to the terms and conditions hereof, the purchase and sale of the Shares contemplated by this Agreement (the “Closing”) will take place at the offices of Simpson Thacher & Bartlett LLP, 425 Lexington Avenue, New York, New York 10017 at 9:00 a.m. New York City time, on September 18, 2006, or such other day and place as the parties may mutually agree. At the Closing, (i) Silver Lake will deliver to the Purchaser certificates representing the Shares to be purchased by the Purchaser duly endorsed or accompanied by stock powers duly executed in blank and otherwise in form acceptable for transfer on the books of the Company (or shall deliver the shares in such other manner as shall be reasonably agreed), (ii) the Purchaser shall deliver the Purchase Price to Silver Lake by wire transfer of immediately available funds to one or more accounts specified by Silver Lake at least one business day prior to the Closing and (iii) Silver Lake and the Purchaser shall deliver executed cross-receipts evidencing delivery of the items set forth in sections (i) and (ii) of this Section.

     2. Representations and Warranties of Silver Lake. In order to induce the Purchaser to enter into this Agreement, Silver Lake hereby represents and warrants to the Purchaser as follows:

          2.1 Ownership of Shares. Silver Lake owns of record the number of issued and outstanding shares of Common Stock set forth in the recitals to this Agreement. The Shares to be sold to the Purchaser by Silver Lake when delivered to the Purchaser shall be free and clear of any liens, claims or encumbrances, including rights of first refusal and similar claims except for restrictions of applicable state and federal securities laws. There are no restrictions on the transfer of such Shares imposed by any shareholder or similar agreement or any law, regulation or order, other than applicable state and federal securities laws.

          2.2 Authorization. Silver Lake has full right, power and authority to execute, deliver and perform this Agreement and to sell, assign and deliver the Shares to be sold by it to the Purchaser. This Agreement is the legal, valid and, assuming due execution and delivery by the other parties hereto, binding obligation of Silver Lake, enforceable in accordance with its terms, except to the extent that the enforceability thereof may be limited by (i) principles of public policy, (ii) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors’ rights generally, and (iii) rules of law governing the availability of equitable remedies.

          2.3 No Violation; No Consent. The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby by Silver Lake (i) will not constitute a breach or violation of or default under any judgment, decree or order or any agreement or instrument of Silver Lake or to which Silver Lake is subject, (ii) will not result in the creation or imposition of any lien upon the Shares to be sold by Silver Lake, and (iii) will not require the consent of or notice to any governmental entity or any party to any contract, agreement or arrangement with Silver Lake.

          2.4 Brokerage. There are no claims for brokerage commissions or finder’s fees or similar compensation in connection with the transactions contemplated by this Agreement based on any arrangement or agreement made by or on behalf of Silver Lake.

     3. Representations and Warranties of the Purchaser. In order to induce Silver Lake to enter into this Agreement, the Purchaser represents and warrants as follows:

          3.1 Organization and Corporate Power; Authorization. This Agreement and any other agreements, instruments, or documents entered into by the Purchaser pursuant to this Agreement have been duly executed and delivered by the Purchaser and are the legal, valid and, assuming due execution by the other parties hereto, binding obligations of the Purchaser, enforceable against the Purchaser in accordance with their terms except to the extent that the enforceability thereof may be limited by (i) principles of public policy, (ii) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors’ rights generally, and (iii) rules of law governing the availability of equitable remedies.

          3.2 No Violation; No Consent.

Each certificate representing the Shares will bear a legend on the face thereof substantially to the following effect (with such additions thereto or changes therein as the Company may be advised by counsel are required by law):

     “THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES OR BLUE SKY LAWS. THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID EXEMPTION THEREFROM UNDER SAID ACT OR LAWS.”

The Purchaser is a sophisticated purchaser with respect to the Shares and has information concerning the business and financial condition of the Company, including, without limitation, information received on a confidential basis directly or indirectly from the Company, to make an informed decision regarding the purchase of the Shares and has independently, and without reliance on Silver Lake, and based on such information it has deemed appropriate in its independent judgment, made its own analysis and decision to purchase the Shares. The Purchaser is an “affiliate,” as defined in Rule 144 under the

3

Securities Act, of the Company. The Purchaser acknowledges that it has had the opportunity to consult with legal counsel with respect to the matters referred to in this Agreement.
