                                                                      Schedule 1

                                    AMENDMENT
                                       TO
                               SAPIENT CORPORATION
                            1998 STOCK INCENTIVE PLAN

      WHEREAS, Sapient Corporation (the "Company") established the 1998 Stock
Incentive Plan effective March 24, 1998 and authorized the issuance of options
to acquire common stock, .01 par value, of the Company thereunder up to a limit
specified in the Plan;

      WHEREAS, on May 8, 1998 the shareholders of the Company voted to approve
the Plan;

      WHEREAS, the Board of Directors of the Company delegated the
administration of the Plan and issuance of the options thereunder to the
Compensation Committee of the Board of Directors (the "Committee");

      WHEREAS, the terms of the Plan provide that, after March 24, 2008, no
further options will be permitted to be issued under the Plan;

      WHEREAS, the Committee has not granted awards for all of the shares of
common stock authorized under the Plan;

      WHEREAS, upon recommendation of the Committee, the Board desires to amend
the Plan to extend the time during which awards can be made under the Plan for a
period of up to 5 years, so that the Committee may grant awards for shares
remaining under the Plan that were authorized previously but remain available
for awards;

      WHEREAS, upon recommendation of the Committee, the Board desires to add a
Plan provision that authorizes the payment of performance-based cash bonuses to
eligible employees, subject to the limitations set forth herein; and

      WHEREAS, Section 11(d) of the Plan reserves to the Company the right to
amend the Plan, provided that no such amendment shall be effective unless and
until approved by stockholders of the Company as required by Section 162(m) of
the Internal Revenue Code of 1986, as amended (the "Code").

      NOW, THEREFORE, the Plan is hereby amended as follows, effective as of
date on which such amendment is approved by stockholders of the Company:

1.    Section 4(b) is amended in its entirety to read as follows:

<PAGE>

      "(b) Per Participant Limit. Subject to adjustment under Section 8, the
      maximum number of shares of Common Stock for which Options may be granted
      to any person in any calendar year and the maximum number of shares of
      Restricted Stock granted to any person in any calendar year will each be
      1,000,000. The maximum number of shares subject to other stock-based
      Awards granted to any person in any calendar year will be one million
      (1,000,000) shares. The maximum dollar amount of any cash bonus payable to
      any single Participant under Section 6A of the Plan in any calendar year
      shall be two million dollars (U.S. $2,000,000). The per-Participant limits
      described in this Section 4(b) shall be construed and applied consistently
      with Section 162(m) of the Code.

2.    A new Section 6A is hereby added to read in its entirety as follows:

      "6A. BONUSES. The Board may grant cash bonus awards ("Bonus Awards") to
      Participants on the terms and conditions set forth herein. The Board shall
      select those Participants (each a "Bonus Participant") under the Plan who
      shall be eligible to receive a Bonus Award, which may be a Performance
      Award, and the terms and conditions of each such Award, including, without
      limitation, with respect to Performance Criteria.

3.    Section 11(c) of the Plan shall be amended to read in its entirety as
      follows:

      "The Plan became effective on May 8, 1998, the date on which it was
      originally adopted by stockholders, and provided that no Awards could be
      granted after March 24, 2008. On March 29, 2007, the Plan was amended,
      subject to stockholder approval, so that no Awards could be granted after
      the first to occur of March 29, 2012, and the time at which no Common
      Stock is available for Awards. Accordingly, no Awards may be made after
      that date, but Awards previously granted may extend beyond that date in
      accordance with their terms. No Incentive Stock Option may be granted
      under the Plan after March 24, 2008.

4.    A new Section 12 is added to read in its entirety as follows:

      "12. PERFORMANCE AWARDS.

      (a) GENERALLY. A Performance Award is an Award that is subject to
      Performance Criteria. The Committee, in its discretion, may grant
      Performance Awards that are intended to qualify for the performance-based
      compensation exception under Section 162(m) of the Code and Performance
      Awards that are not intended so to qualify.

      (b) PERFORMANCE CRITERIA. Performance criteria ("Performance Criteria")
      are specified criteria, other than the mere continuation of Employment or
      the mere passage of time, the satisfaction of which is a condition for the
      grant, exercisability, vesting or full enjoyment of an Award. For purposes
      of Awards

<PAGE>

      that are intended to qualify for the performance-based compensation
      exception under Section 162(m) of the Code, a Performance Criterion will
      mean an objectively determinable measure of performance relating to any or
      any combination of the following (measured either absolutely or by
      reference to an index or indices and determined either on a consolidated
      basis or, as the context permits, on a divisional, subsidiary, line of
      business, project or geographical basis or in combinations thereof):
      sales; revenues; assets; expenses; earnings before or after deduction for
      all or any portion of interest, taxes, depreciation, or amortization,
      whether or not on a continuing operations or an aggregate or per share
      basis; return on equity, investment, capital or assets; one or more
      operating ratios; borrowing levels, leverage ratios or credit rating;
      market share; capital expenditures; cash flow; stock price; stockholder
      return; sales of particular products or services; customer satisfaction
      scores ; acquisitions and divestitures (in whole or in part); joint
      ventures and strategic alliances; spin-offs, split-ups and the like;
      reorganizations; or recapitalizations, restructurings, financings
      (issuance of debt or equity) or refinancings. A Performance Criterion and
      any targets with respect thereto determined by the Board need not be based
      upon an increase, a positive or improved result or avoidance of loss. To
      the extent consistent with the requirements for satisfying the
      performance-based compensation exception under Section 162(m) of the Code,
      the Board may provide, in the case of any Award intended to qualify for
      such exception, that one or more of the Performance Criteria applicable to
      such Award will be adjusted in an objectively determinable manner to
      reflect events (for example, but without limitation, acquisitions or
      dispositions) occurring during the performance period that affect the
      applicable Performance Criterion or Criteria. The Board shall have the
      authority to exercise subjective discretion to reduce (but not increase)
      awards payouts below the levels indicated by the strict application of the
      Performance Criteria, based on factors it deems appropriate in its sole
      discretion."

      Executed this 29th day of March, 2007.
