                             EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT ("Agreement"), made and entered into as of
December 31, 1997 by and between Tracy A. Dixon, a resident of the State of
Georgia ("Employee") and First Community Bank of Southwest Georgia, a Georgia
corporation ("FCB").

                             W I T N E S S E T H:

     WHEREAS, Employee is currently an executive officer of Bainbridge National
Bank, a wholly owned subsidiary of Investors Financial Corp. ("Investors").
Investors has entered into an Agreement and Plan of Merger (the "Merger
Agreement") with FCB's parent corporation, PAB Bankshares, Inc. ("PAB"),
pursuant to which Investors will be merged with and into PAB (the "Merger"), and
subsequently Bainbridge National Bank will be merged with FCB;

     WHEREAS, upon consummation of the Merger, FCB and Employee each desire to
enter into an employment relationship with the other; and

     WHEREAS, FCB and Employee each deem it necessary and desirable, for their
mutual protection, to execute a written document setting forth the terms and
conditions of said relationship;

     NOW, THEREFORE, in consideration of the employment of Employee by FCB, of
the premises and the mutual promises and covenants contained herein, and of
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto, intending to be legally bound, agree as
follows:

     1.  Employment and Duties.

     FCB hereby employs Employee to serve as Chief Executive Officer and to
perform such duties and responsibilities as customarily performed by persons
acting in such capacity.  During the terms of this Agreement, Employee will
devote his full time and effort to his duties hereunder.  Employee will report
directly to the Chief Executive Officer of PAB.

     2.   Term.  Subject to the provisions of Sections 12 and 14 of this
Agreement, the period of Employee's employment under this Agreement shall be
deemed to have commenced as 
<PAGE>
 
of the effective date of the Merger, and shall continue for a period of thirty-
six (36) calendar months thereafter, and any extensions thereafter, unless the
Merger is not consummated or the Employee dies before the end of such thirty-six
(36) months, in which case the period of employment shall continue until the end
of the month of such death. The said thirty-six (36) month period of employment
shall automatically be extended for additional twelve (12) full calendar months
terms without further action by the parties, commencing on the third anniversary
of this Agreement and each anniversary thereafter. No such automatic extension
shall occur if either party shall, at least ninety (90) days prior to any said
anniversary, have served written notice upon the other of its intention that
this Agreement shall not be so extended.

     3.  Compensation.

     For all services to be rendered by Employee during the term of this
Agreement, FCB agrees to pay Employee an annual base salary equal to his
compensation paid by Bainbridge National Bank as of the date of the Merger
Agreement subject to normal annual increase through the Effective Date of the
Merger (the "Base Salary"), less normal withholdings, payable in equal monthly
or more frequent installments as are customary under FCB's payroll practices
from time to time.  FCB's Board of Directors shall review Employee's Base Salary
annually and in its sole discretion may adjust Employee's Base Salary from year
to year, but any reduction during the term of this Agreement shall not occur
unless a similar reduction is made in the base salary of all similarly situated
officers of PAB.  The annual compensation (regardless of form), by the Board
will be done after taking into account, among other things, changes in the cost
of living, Employee's own performance and the performance of FCB.  Any action or
review by the Board may be delegated to an appropriate committee thereof.

     4.   Expenses.

     So long as Employee is employed hereunder, Employee is entitled to receive
reimbursement for, or seek payment directly by FCB of, all reasonable expenses
which are consistent with the normal policy of FCB in the performance of
Employee's duties hereunder, provided that Employee accounts for such expenses
in writing.

                                       2
<PAGE>
 
     5.  Employee Benefits.

     So long as Employee is actively employed hereunder, Employee will be
entitled to participate in the employee benefit, option, bonus and any other
compensation programs covering executive officers of FCB and its affiliated
companies substantially similar to those amounts received by the group of
executive officers of FCB and its affiliated companies disclosed in any PAB
filings as the group of highly compensated employees or similar designation.

     6.  Vacation.

     Employee shall be entitled to a vacation in accordance with FCB's vacation
policy in effect at the time the vacation is to be taken but in no event less
than the current vacation benefit provided to Employee by Bainbridge National
Bank.

     7.  Confidentiality.

     In Employee's position as an employee of FCB, Employee has had and will
have access to confidential information, trade secrets and other proprietary
information of vital importance to FCB and has and will also develop
relationships with customers, employees and others who deal with FCB which are
of value to FCB.  FCB requires as a condition to Employee's employment with FCB
that Employee agrees to certain restrictions on Employee's use of the
proprietary information and valuable relationships developed during Employee's
employment with FCB.  In consideration of the terms and conditions contained
herein, the parties hereby agree as follows:

          7.1  FCB and Employee mutually agree and acknowledge that FCB may
entrust Employee with highly sensitive confidential, restricted and proprietary
information concerning various Business Opportunities (as hereinafter defined),
customer lists, and personnel matters.  Employee acknowledges that he shall bear
a fiduciary responsibility to FCB to protect such information from use or
disclosure that is not necessary for the performance of Employee's duties
hereunder, as an essential incident of Employee's employment with FCB.

                      (i)   that is or becomes generally known to the public;

                      (ii)  that is already known by Employee or is developed by
Employee after termination of employment through entirely independent efforts;

                      (iii) that Employee obtains from an independent source
having a bona fide right to use and disclose such information;

                                       4
<PAGE>
 
                    (iv) that is required to be disclosed by law, except to the
extent eligible for special treatment under an appropriate protective order; or

                    (v) that FCB's Board of Directors approves for release.

     7.3  Employee shall not, without the prior approval of FCB's Board, during
his employment with FCB and for so long thereafter as the information or data
remain Trade Secrets, use or disclose, or negligently permit any unauthorized
person who is not an employee of FCB to use, disclose, or gain access to, any
Trade Secrets of FCB, its affiliates, or of any other person or entity making
Trade Secrets available for FCB's use.

     7.4  Employee shall not, without the prior written consent of FCB, during

disclose, or gain access to, any Confidential Information to which the Employee
obtained access by virtue of his employment with FCB, except as provided in
Section 7.2 of this Agreement.

     Upon the request of FCB and, in any event, upon the termination of his
employment with FCB, Employee shall deliver to FCB all memoranda, notes,
records, manuals or other documents, including all copies of such materials
containing Trade Secrets or Confidential Information, whether made or compiled
by Employee or furnished to him from any source by virtue of his employment with
FCB.

     10.  Severability.

     Employee acknowledges and agrees that the covenants contained in Sections 7
through 9 of this Agreement shall be construed as covenants independent of one
another and distinct from 

                                       5
<PAGE>
 
the remaining terms and conditions of this Agreement, and severable from every
other contract and course of business between FCB and Employee, and that the
existence of any claim, suit or action by Employee against FCB, whether
predicated upon this or any other agreement, shall not constitute a defense to
FCB's enforcement of any covenant contained in Sections 7 through 9 of this
Agreement.

     11.  Specific Performance.

     Employee acknowledges and agrees that the covenants contained in Sections 7
through 9 of this Agreement shall survive any termination of employment, as
applicable, with or without Cause, at the instigation or upon the initiative of
either party.  Employee further acknowledges and agrees that the ascertainment
of damages in the event of Employee's breach of any covenant contained in
Sections 7 through 9 of this Agreement would be difficult, if at all possible.
Employee therefore acknowledges and agrees that FCB shall be entitled in
addition to and not in limitation of any other rights, remedies, or damages
available to FCB in arbitration, at law or in equity, upon submitting whatever
affidavit the law may require, and posting any necessary bond, to have a court
of competent jurisdiction enjoin Employee from committing any such breach.

in Section 14 of this Agreement, if this Agreement is terminated either (i) by
FCB at any time for any reason other than for Cause, (ii) by Employee for Good
Reason or (iii) upon FCB's breach of this Agreement, then FCB shall pay to

FCB, including salary, bonuses, all perquisites, and all other forms of
compensation paid to Employee for his benefit or the benefit of his family,
however characterized, for the fiscal year during the term of this Agreement for

<PAGE>
 
          ALTERNATIVE B

     (i)   twelve (12) payments, each in an amount equal to (A) the product of

Employee and his spouse in this Section 14.2.1 (ii) shall be reduced to the
extent equivalent benefits are provided by the subsequent employer; and

which Employee is entitled under any compensation plan of FCB, at the time such
payments are due.

          14.4.2    During the remaining term of this Agreement following the
effective date of a Change in Control, if FCB takes any of the following
actions, such action shall be deemed to be a termination without Cause.  Those
actions are: (i) a reduction in Employee's salary, bonus provisions or other
perquisites as were in effect immediately prior to a Change in Control, (ii) a

relocate more than fifty (50) 

                                       11

miles from the Main Office. In any such event, Employee shall be entitled to all
payments provided for in Section 14.4.1 of this Agreement.

          15.  Covenant Not to Compete and Not to Solicit.

          15.1 For purposes of this Section 15, FCB and Employee conduct the
following business in the following geographic areas:

               15.1.1  FCB is engaged in the business of transacting business as
a bank which accepts deposits, makes loans, cash checks and otherwise engages in
the business of banking ("Business of FCB").

               15.1.2  After merging with Bainbridge National Bank, FCB will
actively conduct business in the geographic areas of Georgia and Florida from
its main office located at 226 South Broad Street, Bainbridge, Georgia 31717-
3616 (the "Main Office").

               15.1.3  Employee has established business relationships and
performs the duties described in Section 1 of this Agreement in the geographic
area covered by a circle having a radius of fifty (50) miles from the Main
Office, and will work primarily in such area while in the employ of FCB.

          15.2 Employee covenants and agrees that for a period of eighteen (18)
months after the termination of his employment with FCB for any reason, Employee
shall not, directly or indirectly, as principal, agent, trustee, consultant or
through the agency of any corporation, partnership, association, trust or other
entity or person, on Employee's own behalf or for others, provide the duties
described in Section 1 of this Agreement for any entity or person conducting the
Business of FCB within the geographic area covered by a circle having a radius
of fifty (50) miles from the Main Office.

          15.3 Employee acknowledges that an important factor leading to the
Merger is the loyalty of Bainbridge National Bank's employees.  Accordingly,
Employee agrees that both during the term of this Agreement and for a period of
eighteen (18) months after the termination of this Agreement for any reason,
Employee will not enter into, and will not participate in, any plan or
arrangement to cause any FCB employee to terminate his or her employment with
FCB, 

                                       12
<PAGE>
 
and, Employee further agrees that for a period of at least eighteen (18)
months after the termination of employment by any employee of FCB, Employee will
not hire such employee in connection with any business initiated by Employee or
any other person, firm or corporation.  Employee further agrees that information
as to the capabilities of FCB's employees, their salaries and benefits, and any
other terms of their employment is Confidential Information and proprietary to
FCB.

          15.4 Employee and FCB shall periodically amend this Agreement by
updating the address referenced in Section 15.1.2 of this Agreement so that it
at all times lists the then current geographic area served by FCB for which
