                                                                  Execution Copy

                    SEPARATION AND NON-COMPETITION AGREEMENT

This Separation and Non-Competition Agreement (the "Agreement") is made as of
February 25, 2004 by and between Manhattan Associates, Inc. ("Company") and
Peter F. Sinisgalli ("Executive").

NOW, THEREFORE, for good and valuable consideration, the sufficiency of which is
hereby acknowledged, and in consideration of the mutual promises and covenants
set forth in this Agreement, the parties agree as follows:

     1.  Employment. Company has agreed to employ Executive as President and
         Chief Operating Officer effective as of April 12, 2004, and as
         President and Chief Executive Officer effective as of July 1, 2004, in
         accordance with the terms and conditions set forth in this Agreement
         and in the Executive Employment Agreement dated as of even date
         herewith between the Company and the Executive (the "Employment
         Agreement"), and Executive has accepted such employment. This Agreement
         governs the terms by which Executive shall receive certain payments in
         return for a promise not to compete with the business of the Company in
         the event of a termination of his employment.

     2.  Severance. In the event of a termination or Constructive Termination
         (as defined below) of employment by the Company or its successors,
         other than a termination for Cause or the expiration of the Employment
         Agreement, Executive shall receive a severance payment equal to
         eighteen (18) months of Executive's then current base salary, subject
         to all payroll and income tax and other authorized deductions, payable
         in eighteen (18) equal monthly payments from the date of termination,
         including COBRA payments for Executive's family for medical and dental
         coverage. Company's obligation to make the severance payment shall be
         conditioned upon Executive's (i) execution of a release agreement in
         the form attached hereto as Exhibit A, and (ii) compliance with the
         restrictive covenants and all post-termination obligations contained in
         this Agreement.

     3.  Cause. For purposes of this Agreement, Cause shall include but not be
         limited to an act or acts or an omission to act by the Executive
         involving (i) willful and continual failure to substantially perform
         his duties with the Company (other than a failure resulting from the
         Executive's disability) and such failure continues after written notice
         to the Executive providing a reasonable description of the basis for
         the determination that the Executive has failed to perform his duties,
         (ii) indictment for a criminal offense other than a misdemeanor not
         disclosable under the federal securities laws, (iii) breach of this
         Agreement in any material respect where such breach is not susceptible
         to remedy or cure or has not already materially damaged the Company, or
         is susceptible to remedy or cure and no such damage has occurred, is
         not cured or remedied reasonably promptly after written notice to the
         Executive providing a reasonable description of the breach, or (iv)
         conduct that the Board of Directors of the Company has determined, in
         good faith, to be dishonest, fraudulent, unlawful or grossly negligent
         or which is not in compliance with the Company's Code of Conduct or
         similar applicable set of standards or conduct and business practices
         set forth in writing and provided to the Executive prior to such
         conduct.

     4.  Constructive Termination. For purposes of this Agreement, Constructive
         Termination shall mean a situation where (A) (i) the Executive is not
         serving as President and Chief Operating Officer of the Company through
         June 30, 2004 or as President and Chief Executive Officer of the
         Company thereafter through April 12, 2008, the Executive is not timely
         paid his compensation under this Agreement or the assignment to the
         Executive of any duties or responsibilities that are inconsistent with
         the status, title, position or responsibilities of such positions
         (which assignment is not rescinded after the Company receives written
         notice from the Executive providing a reasonable description of such
         inconsistency); (ii) after a Change of Control, the Company's
         headquarters being outside of the Atlanta, Georgia greater metropolitan
         area or the Company requiring the Executive to be based at any place
         outside of the Atlanta, Georgia greater metropolitan area; (iii) after
         a Change of Control, the failure by the Company to provide the

<PAGE>

         Executive with compensation and benefits substantially comparable, in
         the aggregate, to those provided for under the employee benefit plans,
         programs and practices in effect immediately prior to the Change of
         Control (other than stock option and other equity based compensation
         plans); (iv) after a Change of Control, the insolvency or the filing
         (by any party including the Company) of a petition for bankruptcy of
         the Company; or (v) after a Change of Control, the failure of the
         Company to obtain an agreement from any successor or assignee of the
         Company to assume and agree to perform this Agreement unless such
         successor or assignee is bound to the performance of this Agreement as
         a matter of law; provided however, that the aforementioned situations
         will not be deemed to be a Constructive Termination hereunder until
         such time as the Executive has given written notice to the Chairman of
         the Board of the situation constituting a "Constructive Termination"
         hereunder, and the Chairman of the Board has failed to cure such
         situation within thirty (30) days following receipt of such written
         notice, and (B) the Executive terminates his employment with the
         Company.

     5.  Change of Control. In the event of a Change of Control of the Company,
         as defined below, all options, whether vested or non-vested shall vest
         as of the date of the Change of Control. "Change of Control" shall mean
         the happening of an event that shall be deemed to have occurred upon
         the earliest to occur of the following events: (i) the date the
         shareholders of the Company (or the Board, if shareholder action is not
         required) approve a plan or other arrangement pursuant to which the
         Company will be dissolved or liquidated; (ii) the date the shareholders
         of the Company (or the Board, if shareholder action is not required)
         approve a definitive agreement to sell or otherwise dispose of all or
         substantially all of the assets of the Company; or (iii) the date the
         shareholders of the Company (or the Board, if shareholder action is not
         required) and the shareholders of the other constituent corporations
         (or their respective boards of directors, if and to the extent that
         shareholder action is not required) have approved a definitive
         agreement to merge or consolidate the Company with or into another
         corporation, other than, in either case, a merger or consolidation of
         the Company in which holders of shares of the Company's voting capital
         stock immediately prior to the merger or consolidation will have at
         least fifty percent (50%) of the ownership of voting capital stock of
         the surviving corporation immediately after the merger or consolidation
         (on a fully diluted basis), which voting capital stock is to be held by
         each such holder in the same or substantially similar proportion (on a
         fully diluted basis) as such holder's ownership of voting capital stock
         of the Company immediately before the merger or consolidation.

     6.  Non-Competition. As a condition to any payment based on a termination,
         Executive agrees that he will not work for any of the direct
         competitors to Company listed in Schedule A for a period of eighteen
         (18) months from the date of termination without written consent of
         Employer. Further, Executive agrees that he will not recruit or hire,
         another executive of Employer for a period of eighteen (18) months from
         the date of termination or cause another executive of Employer to be
         hired by any competitor of Employer for a period of eighteen (18)
         months from the date of termination.

     7.  Effect of Violations. Executive agrees and understands that any action
         by him in violation of this Agreement shall void Employer's payment to
         the Executive of all severance provided for herein and shall require
         immediate repayment by the Executive of the value of all consideration
         paid to Executive by Employer pursuant to this Agreement, and shall
         further require Executive to pay all reasonable costs and attorneys'
         fees incurred by Company in defending any action Executive brings, plus
         any other damages to which the Employer may be entitled. Company agrees
         and understands that any failure by it to pay Executive any amounts due
         hereunder in violation of this Agreement shall require Company to pay
         all reasonable costs and attorneys' fees incurred by Executive in
         defending any action Company brings, plus any other damages to which
         Executive may be entitled.

     8.  Severability. If any provision, or portion thereof, of this Agreement
         is held invalid or unenforceable under applicable statute or rule of
         law, only that provision shall be deemed omitted from this Agreement,
         and only to the extent to which it is held invalid and the remainder of
         the Agreement shall remain in full force and effect.

     9.  This Agreement shall be governed under the laws of the United States.
