      This Option shall expire and is not exercisable after 5:00 p.m., Atlanta

      Notwithstanding the beginning date for exercise set forth in the second
preceding paragraph, but subject to the provisions of the preceding paragraph
with respect to expiration of this Option, this Option may be exercised as to

entity making such offer purchases or otherwise acquires shares of Common Stock
pursuant to such offer; or (b) any person or group (as such terms are defined in
Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the
'Act')), becomes the holder of 50% or more of the outstanding shares of Common

Option shall be fully exercisable: (x) in the event of (a) above, during the

and ending on the date such offer expires and is not extended; or (y) in the

more of the outstanding shares of Common Stock. In the case of (a) above, if the
Corporation, person or other entity making the offer does not purchase or
otherwise acquire shares of Common Stock pursuant to such offer, then the
Director's right under this paragraph to exercise this Option shall terminate,
the Director and the Corporation shall rescind any exercise of this Option
pursuant to this paragraph, and this Option shall be reinstated as if such
exercise had not occurred.

      4. Exercise Terms. Beginning on the date specified above, and prior to the
expiration of this Option as provided in Section 2 hereof, the Director may
exercise this Option as to all such number of shares, or as to any part thereof,
at any time and from time to time during the remaining term of this Option;
provided that the Director must exercise this Option for at least the lesser of
100 shares or the unexercised portion of the Option. In the event this Option is
not exercised with respect to all or any part of the shares prior to its
expiration, the shares with respect to which this Option was not exercised shall
no longer be subject to this Option.

      5. Option Non-Transferable. This Option and all rights hereunder are
neither assignable nor transferable by the Director otherwise than by will or
under the laws of descent and distribution, or pursuant to a Qualified Domestic
Relations Order, and during the Director's lifetime this Option is exercisable
only by him (or by his guardian or legal representative, should one be
appointed, or qualified transferee). More particularly (but without limiting the
generality of the foregoing), this Option may not be assigned, transferred
(except as aforesaid), pledged or hypothecated in any way (whether by operation
of law or otherwise) and shall not be subject to execution, attachment or
similar process. Any attempted assignment, transfer, pledge, hypothecation or
other disposition of this Option contrary to the provisions hereof shall be null
and void and without legal effect.

      6. Notice of Exercise of Option. This Option may be exercised by the
Director, or by his administrator, executor, personal representative or
qualified transferee, by a written notice (in substantially the form of the
"Notice of Exercise" attached hereto as Annex A) signed by the Director, or by
such administrator, executor, personal representative or qualified transferee,
and delivered or mailed to the Corporation at its principal office in Norcross,
Georgia, to the attention of the President, Treasurer or such other officer as
the Corporation may designate. Any such notice shall (a) specify the number of
shares of Common Stock which the Director or such administrator, executor,
personal representative or qualified transferee, as the case may be, then elects
to purchase hereunder, and (b) be accompanied by (i) a certified or cashier's
check payable to the Corporation, or personal check acceptable to the
Corporation, in payment of the total price applicable to such shares as provided
herein, or (ii) (subject to any restrictions referred to in Annex A) shares of
Common Stock, owned by him and duly endorsed or accompanied by stock transfer
powers, or in lieu thereof, the form of Attestation of Share Ownership attached
as Annex B executed with respect to such number of such shares, having a Fair
Market Value equal to the total purchase price applicable to

<PAGE>

the shares purchased hereunder, or (iii) such a check, and the number of such
shares (or attestation with respect thereto) whose Fair Market Value when added
to the amount of the check equals the total purchase price applicable to such
shares purchased hereunder. Such notice shall also be accompanied by such a
check or shares of Common Stock in payment of applicable withholding and
employment taxes, or the person exercising this Option shall authorize (by use
of Annex B or otherwise) the withholding of shares of Common Stock otherwise
issuable under this Option in payment of such taxes, all as set forth on Annex A
and subject to any restrictions referred to therein. Upon receipt of any such
notice and accompanying payment, and subject to the terms hereof, the
Corporation agrees to cause to be issued to the Director or to such
administrator, executor, personal representative or qualified transferee, as the
case may be, stock certificates for the number of shares specified in such
notice registered in the name of the person exercising this Option.

      7. Adjustment in Option. If prior to the complete exercise of this Option,
there shall be a change in the outstanding Common Stock by reason of one or more
stock splits, stock dividends, combinations or exchanges of shares,
recapitalizations or similar capital adjustments, then the number, kind and
option price of the shares remaining subject to this Option shall be equitably
adjusted in accordance with the terms of the Plan, so that the proportionate
interest in the Corporation represented by the shares then subject to the Option
shall be the same as before the occurrence of such event.

      8. Termination as a Director. If the Director for any reason ceases to be
a member of the Board of Directors of the Corporation (such event being
hereinafter referred to as a 'Termination'), then:

            (a)   To the extent this Option shall have become exercisable on or
                  prior to the date of Termination, it shall remain exercisable
                  until the Expiration Date; and

            (b)   Any portion of this Option that had not become exercisable on
                  or prior to the date of Termination shall immediately
                  terminate and shall not thereafter become exercisable.

      This Option does not confer upon the Director any right with respect to
continuance as a member of the Board of Directors of the Corporation.

      9. Competitive Activities. This Option is subject to Section 9.2 of the
Plan, which provides that if the Director provides services to a competitor of
the Corporation or any of its Subsidiaries, whether as an employee, officer,
director, independent contractor, consultant, agent or otherwise, such services
being of a nature that can reasonably be expected to involve the skills and
experience used or developed by the Director while an employee or Director of
the Corporation or any such Subsidiary, then the Director's rights under this
Option shall thereupon be forfeited and terminated, subject to a determination
to the contrary by the Committee.

      10. Binding Agreement. This Agreement shall be binding upon the parties
hereto and their representatives, successors and assigns.

      IN WITNESS WHEREOF, the Corporation has caused this Stock Option Agreement

the form of Attestation of Share Ownership attached as Annex B to the Agreement,
executed with respect to the number of such shares, having an aggregate Fair

equal, in the aggregate, to the purchase price per share set forth in Section 3

each instance subject to appropriate adjustment pursuant to Section 7 of the
Agreement).

      Also accompanying this Notice is my check in the amount of
$_______________,in payment of federal and state income withholding and
employment taxes applicable to this exercise. The amount of such payment is

may be determined to be necessary or appropriate to comply with Rule 16b-3 under
the Securities Exchange Act of 1934, or to avoid earnings charges or other
adverse consequences to the Corporation under applicable accounting or tax rules

            (1)   I deliver herewith an additional _______________ shares of the
                  Common Stock (or the form of Attestation of Share Ownership

                  this exercise, _______________ such shares having an aggregate
                  Fair Market Value at the date hereof of $ _______________.

      The sum of (i) any such check plus (ii) the Fair Market Value at the date
hereof of any shares of Common Stock specified in the foregoing clauses (1) and
(2) is not less than the amount of federal and state withholding and employment
taxes applicable to this exercise, and is not greater than the total of all
federal and state income and employment taxes to be owed by me as a result of
such exercise.

      IN WITNESS WHEREOF, the undersigned has set his or her hand and seal, this
day of
