                        AMENDMENT TO INVESTOR'S AGREEMENT

         THIS AMENDMENT (this "Amendment) is entered into as of April 28, 2000
to amend the INVESTOR'S AGREEMENT (the "Agreement") entered into as of June 16,
1997, among PAUL BENDER, an individual resident of the State of Virginia
("Bender"), SYNQUEST, INC., a Georgia corporation ("SynQuest"), and WARBURG,
PINCUS INVESTORS, L.P., a Delaware limited partnership ("Warburg").

         In consideration of the mutual promises, representations, warranties
and conditions set forth in this Amendment, Bender, SynQuest and Warburg
mutually agree to amend the Agreement as follows.

         Article V of the Agreement is deleted in its entirety and in its place
is inserted the following Article V:

         ARTICLE V.        PUT RIGHT. On the third anniversary of the Merger
         Agreement, and on each subsequent four (4) anniversaries of the Merger
         Agreement, Bender may elect to put up to twenty percent (20%) of the
         SynQuest Shares (that is, up to 150,000 of the SynQuest Shares per put)
         at a price equal to $8.00 per share (no dividends or accrued interest
         will be payable with respect to the shares).

                  In order to exercise his put rights under this Article, Bender
         must deliver a written notice of his election to SynQuest specifying
         the number of SynQuest Shares Bender elects to sell to SynQuest ("Put
         Election Notice"). Each Put Election Notice will constitute an
         irrevocable election to sell shares identified in the Put Election
         Notice and must be delivered by Bender to SynQuest no later than sixty
         (60) days prior to the anniversary date specified above.

                  Within thirty (30) days of delivery by Bender to SynQuest of
         any Put Election Notice, except as hereinafter provided, SynQuest will
         pay Bender an amount equal to $8.00 per share for the number of shares
         specified in the Put Election Notice, and Bender will deliver to
         SynQuest good title, free and clear of any liens, of such shares.

                  Notwithstanding the foregoing, SynQuest may elect in its sole
         discretion not to purchase the shares offered on the third, and only
         the third, anniversary of the Merger Agreement. SynQuest must notify
         Bender, in writing, of its election not to accept the SynQuest Shares
         ("Postponement Notice") no later than fifteen business days after
         receipt of the Put Election Notice. In the event that SynQuest issues a
         Postponement Notice, Bender may elect to put the shares subject to the
         Postponement Notice only on the earlier of (i) the sale of all or
         substantially all of the assets of SynQuest, or (ii) the fourth
         anniversary of the Merger Agreement in accordance with the notification
         provisions provided for in this Article 5, without forfeiting his
         rights to put any additional shares on subsequent anniversaries of the
         Merger Agreement.

                  Except for any SynQuest Shares subject to a Postponement
         Notice, the put rights granted under this Article automatically expire
         and will be null and void and have no other force and effect upon the
         closing of an underwritten public offering pursuant to an effective
         registration statement under the Securities Act of 1933, as amended
         (the "Securities Act"), covering the offer and sale of Common Stock for
         the account of SynQuest to the public generally.
