SELECTION OF PARTICIPANTS AND DETERMINATION OF AWARDS

The Committee, in its sole discretion, also may designate as Participants one or more individuals (by name or position) who are expected to become Employees during a Performance Period. Participation in the Plan is in the sole discretion of the Committee, and shall be determined on a Performance Period by Performance Period basis. Accordingly, an Employee who is a Participant for a given Performance Period in no way is guaranteed or assured of being selected for participation in any subsequent Performance Period.

     3.2 Determination of Performance Goals. The Committee, in its sole discretion, shall establish the Performance Goals for each Participant for the Performance Period. Such Performance Goals shall be set forth in writing.

     3.3 Determination of Target Awards. The Committee, in its sole discretion, shall establish a Target Award for each Participant. Each Participant’s Target Award shall be determined by the Committee in its sole discretion, and each Target Award shall be set forth in writing.

     3.4 Determination of Payout Formula or Formulae. On or prior to the Determination Date for a Performance Period, the Committee, in its sole discretion, shall establish a Payout Formula or Formulae for purposes of determining the Actual Award (if any) payable to each Participant. Each Payout Formula shall (a) be in writing, (b) be based on a comparison of actual performance to the Performance Goals, (c) provide for the payment of a Participant’s Target Award if the Performance Goals for the Performance Period are achieved at the predetermined level, and (d) provide for the payment of an Actual Award greater than or less than the Participant’s Target Award, depending upon the extent to which actual performance exceeds or falls below the Performance Goals. Notwithstanding the preceding, in no event shall a Participant’s Actual Award for any Performance Period exceed the Maximum Award.

     3.5 Date for Determinations. The Committee shall make all determinations under Sections 3.1 through 3.4 on or before the Determination Date.

     3.6 Determination of Actual Awards. After the end of each Performance Period, the Committee shall certify in writing (for example, in its meeting minutes) the extent to which the Performance Goals applicable to each Participant for the Performance Period were achieved or exceeded, as determined by the Committee. The Actual Award for each Participant shall be determined by applying the Payout Formula to the level of actual performance that has been certified in writing by the Committee. Notwithstanding any contrary provision of the Plan, the Committee, in its sole discretion, may (a) eliminate or reduce the Actual Award payable to any Participant below that which otherwise would be payable under the Payout Formula, and (b) determine whether or not any Participant will receive an Actual Award in the event the Participant incurs a Termination of Employment prior to the date the Actual Award is to be paid pursuant Section 4.2 below.

SECTION 4
PAYMENT OF AWARDS

     4.1 Right to Receive Payment. Each Actual Award that may become payable under the Plan shall be paid solely from the general assets of the Company or the Affiliate that employs the Participant (as the case may be), as determined by the Committee. Nothing in this Plan shall be construed to create a trust or to establish or evidence any Participant’s claim of any right to payment of an Actual Award other than as an unsecured general creditor with respect to any payment to which he or she may be entitled.

     4.2 Timing of Payment. Subject to Section 3.6, payment of each Actual Award shall be made as soon as administratively practicable, but in no event later than two and one-half months after the end of the applicable Performance Period.

     4.3 Form of Payment. Each Actual Award shall be paid in cash (or its equivalent) in a single lump sum.

     4.4 Termination of Employment. If a Participant incurs a Termination or Employment for any reason prior to the end of the Performance Period, such Participant shall not be entitled to an Award. If a Participant incurs a Termination of Employment due to death, disability or an involuntary termination prior to the payment of an Actual Award (determined under Section 3.6) that was scheduled to be paid to him or her prior to such Termination of Employment for a prior Performance Period, the Award shall be paid to the Participant or, if applicable, to his or her designated beneficiary or, if no beneficiary has been designated, to his or her estate.

SECTION 5
ADMINISTRATION

     5.1 Committee is the Administrator. The Plan shall be administered by the Committee. The Committee shall consist of not less than two (2) members of the Board. The members of the Committee shall be appointed from time to time by, and serve at the pleasure of, the Board. Each member of the Committee shall qualify as an “outside director” under Section 162(m) of the Code.

If it is later determined that one or more members of the Committee do not so qualify, actions taken by the Committee prior to such determination shall be valid despite such failure to qualify. Any member of the Committee may resign at any time by notice in writing mailed or delivered to the Secretary of the Company. As of the Effective Date of the Plan, the Plan shall be administered by the Compensation Committee of the Board.

     5.2 Committee Authority. It shall be the duty of the Committee to administer the Plan in accordance with the Plan’s provisions. The Committee shall have all powers and discretion necessary or appropriate to administer the Plan and to control its operation, including, but not limited to, the power to (a) determine which Employees shall be granted awards, (b) prescribe the terms and conditions of awards, (c) interpret the Plan and the awards, (d) adopt such procedures and subplans as are necessary or appropriate to permit participation in the Plan by Employees who are foreign nationals or employed outside of the United States, (e) adopt rules for the administration, interpretation and application of the Plan as are consistent therewith, and (f) interpret, amend or revoke any such rules.

     5.3 Decisions Binding. All determinations and decisions made by the Committee, the Board, and any delegate of the Committee pursuant to the provisions of the Plan shall be final, conclusive, and binding on all persons, and shall be given the maximum deference permitted by law.

     5.4 Delegation by the Committee. The Committee, in its sole discretion and on such terms and conditions as it may provide, may delegate all or part of its authority and powers under the Plan to one or more directors and/or officers of the Company; provided, however, that the Committee may not delegate its authority and/or powers with respect to awards that are intended to qualify as performance-based compensation under Section 162(m) of the Code.

SECTION 6
GENERAL PROVISIONS

     6.1 Tax Withholding. The Company or an Affiliate, as determined by the Committee, shall withhold all applicable taxes from any Actual Award, including any federal, state, local and other taxes.

     6.2 No Effect on Employment. Nothing in the Plan shall interfere with or limit in any way the right of the Company or an Affiliate, as applicable, to terminate any Participant’s employment or service at any time, with or without cause. For purposes of the Plan, transfer of employment of a Participant between the Company and any one of its Affiliates (or between Affiliates) shall not be deemed a Termination of Employment. Employment with the Company and its Affiliates is on an at-will basis only. The Company expressly reserves the right, which may be exercised at any time and without regard to when during or after a Performance Period such exercise occurs, to terminate any individual’s employment with or without cause, and to treat him or her without regard to the effect which such treatment might have upon him or her as a Participant.

     6.3 Participation. No Employee shall have the right to be selected to receive an award under this Plan, or, having been so selected, to be selected to receive a future award.

     6.4 Indemnification. Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified and held harmless by the Company against and from (a) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or any award, and (b) from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Certificate of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any power that the Company may have to indemnify them or hold them harmless.

     6.5 Successors. All obligations of the Company and any Affiliate under the Plan, with respect to awards granted hereunder, shall be binding on any successor to the Company and/or such Affiliate, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business or assets of the Company or such Affiliate.

     6.6 Beneficiary Designations.

     a. Designation. Each Participant may, pursuant to such uniform and nondiscriminatory procedures as the Committee may specify from time to time, designate one or more Beneficiaries to receive any Actual Award payable to the Participant at the time of his or her death. Notwithstanding any contrary provision of this Section 6.6 shall be operative only after (and for so long as) the Committee determines (on a uniform and nondiscriminatory basis) to permit the designation of Beneficiaries.

     b. Changes. A Participant may designate different Beneficiaries (or may revoke a prior Beneficiary designation) at any time by delivering a new designation (or revocation of a prior designation) in like manner. Any designation or revocation shall be effective only if it is received by the Committee. However, when so received, the designation or revocation shall be effective as of the date the designation or revocation is executed (whether or not the Participant still is living), but without prejudice to the Committee on account of any payment made before the change is recorded. The last effective designation received by the Committee shall supersede all prior designations.

     c. Failed Designation. If the Committee does not make this Section 6.6 operative or if Participant dies without having effectively designated a Beneficiary, the Participant’s Account shall be payable to the general beneficiary shown on the records of the Employer. If no Beneficiary survives the Participant, the Participant‘s Account shall be payable to his or her estate.

     6.7 Nontransferability of Awards. No award granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will, by the laws of descent and distribution, or to the limited extent provided in Section 6.6. All rights with respect to an award granted to a Participant shall be available during his or her lifetime only to the Participant.

     6.8 Deferrals. The Committee, in its sole discretion, may permit a Participant to defer receipt of the payment of cash that would otherwise be delivered to a Participant under the Plan. Any such deferral elections shall be made into the Gartner, Inc. Deferred Compensation Plan (or such other similar nonqualified deferred compensation plan in effect at the time) and subject to such rules and procedures as shall be determined by the Committee in its sole discretion.

SECTION 7
AMENDMENT, TERMINATION AND DURATION

     7.1 Amendment, Suspension or Termination. The Board or the Committee, each in its sole discretion, may amend or terminate the Plan, or any part thereof, at any time and for any reason. The amendment, suspension or termination of the Plan shall not, without the consent of the Participant, alter or impair any rights or obligations under any Target Award theretofore granted to such Participant. No award may be granted during any period of suspension or after termination of the Plan.

     7.2 Duration of the Plan. The Plan shall commence on the date specified herein, and subject to Section 7.1 (regarding the Board or the Committee’s right to amend or terminate the Plan), shall remain in effect thereafter.

     8.3 Requirements of Law. The granting of awards under the Plan shall be subject to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required.
