                               AMENDMENT NO. 1 TO
                          SUBORDINATED PROMISSORY NOTES

         This Amendment No. 1 (the "Amendment"), dated as of August 7, 2000, is
entered into by and between SynQuest, Inc., a Georgia corporation formerly known
as Factory Automation & Computer Technologies, Inc. ("Maker"), and Warburg,
Pincus Investors, L.P., a Delaware limited partnership ("Holder").

                                   WITNESSETH:

         WHEREAS, Maker and Holder entered into series of Subordinated
Promissory Notes (the "Notes"), between May 10, 1995 and July 20, 1997, as more
specifically described on Exhibit A attached hereto; and

         WHEREAS, Maker and Holder desire to amend each of the Notes as set
forth below.

         NOW, THEREFORE, in consideration of the foregoing promises and
covenants set forth below, and for other good and valuable consideration, the
receipt and sufficiency of which are acknowledged hereby, Maker and Holder
hereby agree to amend each of the Notes as follows:

         1.       Amendment. Each of the Notes is hereby amended by inserting a
new section immediately following the section entitled "Subordination" as
follows:

                                   "CONVERSION

         Holder shall have the right to convert this Note into shares of Maker's
common stock, par value $0.01 per share ("Common Stock"), as follows:

                  (1)      Holder shall have the right, at its option, at any
time prior to the completion of an initial public offering of Maker's Common
Stock, to convert this Note into shares of Maker's Common Stock by giving
written notice to Maker (a "Conversion Notice") that Holder has elected to
convert all, but not less than all, of the outstanding principal amount plus
accrued interest through the Conversion Date of this Note into shares of Common
Stock (a "Conversion") on the terms described below. Any such Conversion shall
be in full and complete satisfaction of this Note effective as of the Conversion
Date. This Note shall be convertible into such number of whole shares of Maker's
Common Stock as is determined by dividing (a) (i) the outstanding principal
amount of this Note as of the Conversion Date plus (ii) all accrued interest
thereon as of the Conversion Date by (b) the Conversion Price For purposes of
this section, (i) "Conversion Date" shall mean the later of the date on which
the Conversion Notice is delivered or the date that this Note is surrendered to
Maker in connection therewith;

<PAGE>   2

provided, however, that if the Conversion Date is prior to completion of Maker's
initial public offering of Common Stock, the Conversion Date shall be
automatically and without any further action on the part of either Maker or
Holder delayed to the date of completion of the initial public offering and (ii)
"Conversion Price" shall mean the "price to public" of the shares of Common
Stock sold in connection with Maker's initial public offering of Common Stock,
less underwriting discounts and commissions.

                  (2)      In order to exercise the Conversion right, Holder
shall (i) deliver the Conversion Notice described in paragraph (1) and (ii)
surrender this Note, duly endorsed or assigned to Maker or in blank, at the
principal office of Maker. In connection with a Conversion, Holder shall execute
and deliver to Maker such agreements as are reasonably requested by Maker,
including, without limitation, such representations, warranties and covenants
that, in Maker's judgment are necessary for compliance with applicable
securities laws. As promptly as practicable after the completion of Maker's
initial public offering of Common Stock, Maker shall issue and shall deliver to
Holder a certificate or certificates for the number of shares of Common Stock
issuable upon the Conversion of this Note in accordance with the terms hereof,
and any fractional interest in respect of a share of Common Stock arising upon
such Conversion shall be settled as provided in paragraph (3) below. Any
Conversion shall be deemed to have been effected on the applicable Conversion
Date, and Holder shall be deemed to have become the holder of record of the
Common Stock issued in connection with such Conversion at such time on such
date, unless the stock transfer books of Maker shall be closed on that date, in
which event Holder shall be deemed to have become the holder of record at the
close of business on the next succeeding day on which such stock transfer books
are open. All shares of Common Stock delivered upon Conversion of this Note will
upon delivery be duly and validly issued and fully paid and nonassessable.

                  (3)      No fractional shares or scrip representing fractions
of shares of Common Stock shall be issued upon Conversion of this Note. Instead
of any fractional interest in a share of Common Stock that would otherwise be
deliverable upon the Conversion of this Note, Maker shall pay to Holder an
amount in cash (rounded to the nearest cent) equal to the Conversion Price
multiplied by the fraction of a share of Common Stock represented by such
fractional interest.

                  (4)      Maker covenants that it will at all times reserve and
keep available, free from preemptive rights, out of the aggregate of its
authorized but unissued shares of Common Stock or its issued shares of Common
Stock held in its treasury, or both, for the purpose of effecting Conversion of
this Note, the full number of shares of Common Stock deliverable upon the
Conversion of this Note."

         2.       Entire Agreement. Each of the Notes, as amended by this
Amendment, sets forth the entire understanding of the parties with respect to
the Notes.

         3.       Effect of Amendment. On or after the date hereof, each
reference in the Notes to "this Note," "hereunder," "hereof," "herein," or words
of like import, and each

                                       2
<PAGE>   3

reference in any other documents entered into in connection with the Notes,
shall mean and be a reference to each such Note, as amended hereby.

         4.       No Further Amendment. Except as specifically amended above,
each of the Notes shall remain in full force and effect and is hereby ratified
and confirmed.

         5.       Governing Law. This Amendment shall be governed by and
construed in accordance with the laws of the State of Georgia.

         6.       Counterparts. This Amendment may be executed in multiple
counterparts, each of which when executed and delivered is an original but all
of which taken together constitute one and the same instrument.

                                       3

         IN WITNESS THEREOF, this Amendment No. 1 to Subordinated Promissory
Notes has been duly executed as of the date first written above.

                                    AGREEMENT
                                    ---------

     THIS AGREEMENT, entered into this 26th day of April, 2000 by and
between Potters Financial Corporation, a savings and loan holding company
incorporated under Ohio law (hereinafter referred to as "PFC"); Potters Bank, a
savings bank incorporated under Ohio law and a wholly-owned subsidiary of PFC
(hereinafter referred to as "PB"); and Edward L. Baumgardner, an individual
(hereinafter referred to as the "ELB");

                                  WITNESSETH:

     WHEREAS, ELB is the President of PFC and PB (hereinafter collectively
referred to as "POTTERS");

     WHEREAS, the Boards of Directors of POTTERS desire to retain the
services of ELB as the President of POTTERS;

     WHEREAS, ELB desires to continue to serve as the President of POTTERS;
and

     WHEREAS, ELB and POTTERS desire to enter into this Agreement to set
forth the rights and obligations of ELB and POTTERS in the event of the
termination of ELB's employment under the circumstances set forth in this
Agreement;

     NOW, THEREFORE, in consideration of the premises and mutual covenants
herein contained, POTTERS and ELB hereby agree as follows:

     Section l.    TERMINATION OF EMPLOYMENT.

     (a) In the event of the termination of the employment of ELB (i)
without ELB's prior written consent, (ii) for any reason other than JUST CAUSE
(hereinafter defined) and (iii) in connection with or within one year following
a CHANGE OF CONTROL (hereinafter defined) of POTTERS, then the following shall
occur:
              (I) POTTERS shall pay to ELB or, in the event of the
         death of ELB, to the estate of ELB, an amount equal to the
         SEVERANCE PAYMENT (hereinafter defined), subject to standard
         withholding, within ten (10) days after such termination;

              (II) To the extent permitted by the benefit plans of
         POTTERS, ELB and his dependents shall continue to be covered
         under all such plans at POTTERS' expense as if ELB were still
         employed by POTTERS until

<PAGE>   2

                  the earliest of the expiration of the TERM (hereinafter
                  defined) or the date on which ELB is included in another
                  employer's benefit plans as a full-time employee; and

              (III) ELB shall not be required to mitigate the
         amount of any payment provided for in this Agreement by
         seeking other employment or otherwise, nor shall any amounts
         received from other employment or otherwise by ELB offset in
         any manner the obligations of POTTERS hereunder, except as
         specifically stated in subparagraph (II).

In the event that payments pursuant to this Section 1(a) would result in the
imposition of a penalty tax pursuant to Section 280G(b) (3) of the Internal
Revenue Code of 1986, as amended, and the regulations promulgated thereunder,
such payments shall be reduced to the maximum amount which may be paid under
Section 280G without exceeding such limits.

     (b) In the event of the occurrence of any of the following events (i)
without the prior written consent of ELB and (ii) within one year following a
CHANGE OF CONTROL of POTTERS, ELB may voluntarily terminate his employment with
POTTERS:

                           (i) The requirement that ELB move his personal
                  residence or perform his principal executive functions more
                  than thirty-five (35) miles from his primary office as of the
                  date of this Agreement;

                           (ii) A reduction in ELB's base compensation as in
                  effect on the date of this Agreement or as the same may have
                  been increased from time to time;

                           (iii) The failure by POTTERS to continue to provide
                  ELB with compensation and benefits substantially similar to
                  those provided to him under any of the employee benefit plans
                  in which ELB becomes a participant or the taking of any action
                  by POTTERS which would directly or indirectly reduce any of
                  such benefits or deprive ELB of any material fringe benefit
                  potentially enjoyed by him at the time of the CHANGE OF
                  CONTROL;

                           (iv) The assignment to ELB of material duties and
                  responsibilities other than those normally associated with his
                  position as referenced in the recitals above; or

                           (v) A material diminution or reduction in ELB's
                  responsibilities or authority (including reporting
                  responsibilities) in connection with his employment with
                  POTTERS.

                                      -2-
<PAGE>   3

Within ten (10) days after the voluntary termination of ELB's employment in
accordance with this Section 1(b), POTTERS shall pay to ELB or, in the event of
the death of ELB, to the estate of ELB, an amount equal to the SEVERANCE
PAYMENT, subject to standard withholding.

     (c) In the event the  employment of ELB is  terminated  under
circumstances other than as set forth in paragraphs (a) and (b) of this Section
1, ELB shall not be entitled to any severance pay or benefits. Without limiting
the generality of the foregoing sentence, ELB acknowledges that this Agreement
is not a contract of employment; that ELB has no guaranteed term of employment;
and that ELB is an employee at will, subject to termination at any time, with or
without notice or cause.

     Section 2. DEFINITIONS. (a) A "CHANGE OF CONTROL" shall be deemed to
have occurred in the event that, at any time during the TERM, either any person
or entity obtains "conclusive control" of POTTERS within the meaning of 12
C.F.R. Section 574.4(a), or any person or entity obtains "rebuttable control" of
POTTERS within the meaning of 12 C.F.R. Section 574.4(b) and has not rebutted
control in accordance with 12 C.F.R. Section 574.4(e).

     (b) "JUST CAUSE" shall mean personal dishonesty, incompetence, willful
misconduct, breach of fiduciary duty involving personal profit, failure or
refusal to perform the duties and responsibilities assigned by the Boards of
Directors of POTTERS,  violation of any law, rule, regulation or final
cease-and-desist order (other than traffic violations or similar offenses),
conviction of a felony or for fraud or embezzlement, or material breach of any
provision of this Agreement.

     (c) "SEVERANCE PAYMENT" shall mean the product of 2.0, multiplied by
the TOTAL REMUNERATION paid by POTTERS to ELB for the calendar year preceding
termination of employment.

     (d) "TOTAL REMUNERATION" shall mean the sum of (i) base salary, (ii)
bonuses, (iii) incentives, (iv) commissions and (v) other benefits, including,
but not limited to, health and life insurance, club dues, contributions made by
POTTERS to the 401-K plan and the Employee Stock Ownership Plan and the taxable
value of an employer-provided automobile, if any.

     Section 3. TERM. The term of this Agreement shall commence on the date
first above written and shall continue for a period of three (3) years
thereafter (herein referred to as the "TERM"); provided, however, that in the
event of a CHANGE OF CONTROL during the third year of the TERM, the TERM shall,
automatically and without further act, be extended for a period of fifteen (15)
months following such CHANGE OF CONTROL.

     Section 4. SPECIAL REGULATORY EVENTS. Notwithstanding Section 1 of this
Agreement, the obligations of POTTERS to ELB shall be as follows in the event of
the following circumstances:

     (a) If ELB is suspended and/or temporarily prohibited from
participating in the conduct of the POTTERS' affairs by a notice served under
section 8(e) (3) or (g) (1) of the

                                      -3-
<PAGE>   4

Federal Deposit Insurance Act (hereinafter referred to as the "FDIA"), POTTERS'
obligations under this Agreement shall be suspended as of the date of service of
such notice, unless stayed by appropriate proceedings.

     (b) If ELB is removed and/or permanently prohibited from participating
in the conduct of POTTERS' affairs by an order issued under Section 8(e) (4) or
(g) (l) of the FDIA, all obligations of POTTERS under this Agreement shall
terminate as of the effective date of such order; provided, however, that vested
rights of ELB shall not be affected by such termination.

     (c) If POTTERS is in default, as defined in section 3(x) (1) of the
FDIA, all obligations under this Agreement shall terminate as of the date of
default; provided, however, that vested rights of ELB shall not be affected.

     (d) All obligations under this Agreement shall be terminated, except to
the extent of a determination that the continuation of this Agreement is
necessary for the continued operation of POTTERS, (i) by the Federal Deposit
Insurance Corporation (hereinafter referred to as the "FDIC") at the time that
the FDIC enters into an agreement to provide assistance to or on behalf of
POTTERS under the authority contained in Section 13(c) of the FDIA or (ii) by
the FDIC at any time the FDIC approves a supervisory merger to resolve problems
related to the operation of POTTERS or when POTTERS is determined by the FDIC to
be in an unsafe or unsound condition. No vested rights of ELB shall be affected
by any such action.

     Section 5. NONASSIGNABILITY. Neither this Agreement nor any right or
interest hereunder shall be assignable by ELB without POTTERS' prior written
consent; provided, however, that nothing in this Section 5 shall preclude ELB
from designating a beneficiary to receive any benefits payable hereunder upon
his death.

     Section 6. NO ATTACHMENT. Except as required by law, no right to
receive payment under this Agreement shall be subject to  anticipation,
commutation, alienation, sale, assignment, encumbrance, charge, pledge or
hypothecation or to execution,  attachment, levy, or similar process of
assignment by operation of law, and any attempt, voluntary or involuntary, to
effect any such action shall be null, void and of no effect.

     Section 7. BINDING AGREEMENT. This Agreement shall be binding upon, and
inure to the benefit of, ELB and POTTERS and their respective heirs, executors,
personal representatives, successors and assigns.

     Section 8. WAIVER. No term or condition of this Agreement shall be
deemed to have been waived, nor shall there be an estoppel against the
enforcement of any provision of this Agreement, except by written instrument of
the party charged with such waiver or estoppel. No such written waiver shall be
deemed a continuing waiver, unless specifically stated therein, and each waiver
shall operate only as to the specific term or condition waived and shall not
constitute a waiver of such term or condition for the future or as to any act
other than the act specifically waived.

         Section 9. SEVERABILITY. If, for any reason, any provision of this
Agreement is held invalid, such invalidity shall not affect the other provisions
of this Agreement not held so invalid, and each such other provision shall, to
the full extent consistent with applicable law, continue in full force and
effect. If this Agreement is held invalid or cannot be enforced, then any prior
Agreement between POTTERS (or any predecessor thereof) and ELB shall be deemed
reinstated to the full extent permitted by law, as if this Agreement had not
been executed.

         Section 10. HEADINGS. The headings of the paragraphs herein are

delivered in the State of Ohio and its validity, interpretation, performance,
and enforcement shall be governed by the laws of the State of Ohio, except to
the extent that federal law is governing.

         Section 12. EFFECT OF PRIOR AGREEMENTS. This Agreement contains the
entire understanding between the parties hereto and supersedes any prior
employment agreement between POTTERS and ELB, each of which is hereby terminated
and is of no further force or effect.
