                                    ARTICLE 1

                             RESTRICTIONS ON SHARES

         1.1 Restrictions on Transfer of Shares. The Shares shall be subject to
the following restrictions:

                  (a) Except for transfers made in compliance with Section

                  (b) A Shareholder (or any Transferee as defined in Section

         such Transferee only:

                           (i) to a Transferee, provided that all such Shares
                  shall remain subject to the restrictions set forth in this
                  Section 1.1 and all applicable rights in favor of the Company
                  set forth elsewhere herein in the hands of the Transferee and
                  any subsequent Transferee;


   2


                           (ii)  in connection with one of the following
                  transactions: (A) dissolution or liquidation of the Company,
                  (B) merger of the Company into another company, or any
                  consolidation, share exchange, combination, reorganization or
                  like transaction the consummation of which is subject to prior
                  approval by the shareholders of the Company, (C) sale or
                  transfer (other than as security for the Company's credit
                  obligations) of substantially all of the assets of the
                  Company, or (D) in a transfer pursuant to Articles 3 or 7
                  hereof; or

                           (iii) in strict compliance with the right of first
                  refusal described in Article 2 below.

                 (c) Any Transferee shall, as a condition to the transfer of any
         Shares to the Transferee, become a party to this Agreement and shall
         thereupon be deemed a "Shareholder" hereunder.


                                    ARTICLE 2

                             RIGHT OF FIRST REFUSAL

         2.1 Right of First Offer. If a Shareholder shall receive a bona fide
offer from a third party for such third party to purchase any Shares owned by
such Shareholder, which offer such Shareholder intends to accept, such
Shareholder, before accepting such third party offer or consummating the sale to
such third party, shall notify the Company in writing of such offer, which
notice shall state the number of Shares subject to such offer and the price and
terms of payment offered by such third party. The Company shall have thirty (30)
days after receipt by it of such notice within which to notify the Shareholder,
in writing, of its election to purchase all (but not less than all) of the
Shares that are the subject of such third party offer at the same price and upon
the same terms and conditions as are contained in such third party offer.
Failure by the Company to give such written notice within such thirty (30) day
period shall constitute a rejection of such offer by the Company. If the Company
rejects such offer or fails timely to accept such offer, or if after timely
accepting such offer the Company fails timely to consummate the purchase of the
Shares that are the subject of that offer, then such Shareholder shall be free
to sell the Shares that are the subject of such third party offer to the third
party at the price and upon the same terms and conditions as are set forth in
the third party offer; provided, however, if such Shareholder does not
consummate such sale to the third party within ninety (90) days after rejection
by the Company of the offer, or, if such offer is timely accepted by the
Company, after failure of the Company timely to consummate such purchase, the
Shares that were the subject of such third party offer shall once again become
subject to the provisions of this Section 2.1, and any subsequent disposition of
such Shares shall be made only after compliance with the terms of this Section
2.1. If the Company timely accepts such offer, the consummation by the Company
of the purchase of Shares that are the subject of the offer shall be held at the
offices of the Company not later than sixty (60) days following the date the
Company gives written notice of its acceptance of such offer.

                                    ARTICLE 3

                           COMPANY'S REPURCHASE RIGHT

         3.1 Right to Sell and Purchase Shares. Upon the occurrence of a
Repurchase Event (as defined in Section 9.12(f) hereof) with respect to a
Shareholder:

         (a) The Shareholder (or his personal representative, executor or
administrator, as the case may be) and/or a Transferee of such Shareholder shall
have the right to sell to the Company all or any portion of the Shares owned by
the Shareholder and/or such Transferee at a price per share equal to the
Purchase Price (as defined in Section 3.2) upon the terms and conditions set
forth herein. A Shareholder and/or a Transferee may exercise his right to sell
the Shares owned by such Shareholder and/or such Transferee by giving written
notice to the Company within one month following the occurrence of the
Repurchase Event giving rise to such right, provided, however, if the Repurchase
Event is the death or disability of a Shareholder, notice may be given within
six months following the Repurchase Event.

         (b) During the respective periods described in Section 3.1(a) and for
the period of ninety (90) days following the expiration of the applicable period
described in that Section, the Company shall have the right to purchase all or
any portion of the Shares owned by such Shareholder (or his personal
representative, executor or administrator, as the case may be) and/or a
Transferee of such Shareholder at a price per share equal to the Purchase Price
upon the terms and conditions set forth herein. The Company may exercise its
right to purchase the Shares owned by such Shareholder and/or such Transferee by
giving written notice to such Shareholder and/or Transferee within the
applicable period following the occurrence of the Repurchase Event giving rise
to such right or within the ninety (90) day period following the expiration of
such applicable period.

         3.2 Purchase Price. The Purchase Price shall be (a) upon the occurrence
of a Repurchase Event, (i) the greater of Fair Value Per Share (as defined in
Section 9.12(d) hereof) or Cost (as defined in Section 9.12(c) hereof) due to
the termination of such Shareholder's employment for any reason other than by
the Company for Cause, and (ii) the lesser of Fair Value Per Share or Cost due
to the termination of Shareholder's employment by the Company for Cause, and (b)
for any other purpose, Fair Value Per Share.

         3.3 Closing of Repurchase. The closing of any purchase of the Shares
owned by such Shareholder and/or such Transferee pursuant to this Article 3
shall take place at the principal office of the Company not earlier than thirty
(30) nor later than forty-five (45) days after the date of the written notice by
a Shareholder and/or a Transferee of the exercise of his right to sell, and the
date of the Company's written notice of the exercise of its right to purchase
such Shares pursuant to this Article 3. At the closing of any purchase of Shares
pursuant to this Article 3, such Shareholder (or his personal representative,
executor or administrator, or such Transferee, as the case may be) shall deliver
all stock certificates representing the Shares to be purchased, properly
endorsed for transfer, and the Company shall pay the transferor at such time and
against delivery of the Shares (a) the aggregate purchase price for the Shares
being purchased; provided, 



                                      -3-
   4

however, if the Board of Directors of the Company shall determine in good faith
that payment of the entire aggregate purchase price for the Shares is not
permitted by the Company's loan agreements or would constitute an unlawful
distribution by the Company, then the Company shall have the right, if the
Company's loan agreements permit the Company to incur the indebtedness created
by such deferred payment, to pay for such Shares by executing and delivering to
such Shareholder (or his personal representative, executor or administrator or
such Transferee, as the case may be), the Company's unsecured promissory note
for the aggregate purchase price. Such note shall be payable to the order of the
transferor and shall bear interest at the annual rate of interest equal to the
annual rate of interest the Company is paying on the date of the closing of such
repurchase on borrowings from its senior lenders, with accrued and unpaid
interest being due on each principal installment payment date. To the extent
that the loan agreements to which the Company is a party permit the payment
annually of an amount greater than the aggregate amount then payable annually
under any note or notes issued as above provided, the Company shall use its best
efforts to obtain the consent (if required) of the lenders who are parties to
such loan agreements to permit such additional amounts to be applied in
prepayment of any such note or notes, and if such consent is obtained (or if no
such consent is required) the Company shall pay such additional amounts in
prepayment of such note or notes (with such prepayment being made pro rata based
upon the outstanding principal amount of all such notes in the event more than
one such note shall be outstanding), with any such prepayment being applied in
inverse order of maturity.

         3.4 Death of Shareholder During Payout. In the event of the death of
such Shareholder after payment has commenced under Section 3.3, the terms and
amounts of payment due to such Shareholder shall continue unchanged, and
payments shall be made to such Shareholder's estate or personal representative.

                                    ARTICLE 4

                    ASSIGNMENT OF COMPANY'S RIGHT TO PURCHASE

         If the Company shall at any time during the term of this Agreement have
the right to purchase from a Shareholder and/or a Transferee of a Shareholder,
as the case may be, any shares of the capital stock of the Company then owned by
such Shareholder or such transferee, and the Company at such time is either
unable, or elects not, to exercise such right with respect to all or any part of
such shares of capital stock, the Company may, but shall not be obligated to,
assign its rights and delegate its obligations hereunder to CGW which may then
exercise all of the rights of the Company with respect to the purchase of such
shares of capital stock as to which such rights are assigned.

                                    ARTICLE 5

                            FAILURE TO DELIVER SHARES

         If a Shareholder or a Transferee, as the case may be, becomes obligated
to sell all or any portion of the Shares to the Company and/or to CGW under of
this Agreement but fails to present the certificate(s) for such Shares at the
closing of such purchase, then the Company and/or CGW, as the case may be, shall
transfer the purchase price for such Shares to a trustee (which shall be a bank
or trust company located in the State of Georgia), for the benefit of such
Shareholder and/or such Transferee, as the case may be, and thereupon such
portion of the Shares shall (a) in the case of a purchase by the Company be
deemed as of the date of such transfer of the purchase price to have been
redeemed and canceled and no longer outstanding, and (b) in the case of a
purchase by CGW be deemed transferred and conveyed to CGW, and the Company may
cancel certificates for such shares and may issue new certificates for such
shares in the name of CGW. The Company or CGW, as the case may be, shall
promptly inform such Shareholder and/or such Transferee, as the case may be, of
the name and address of the trustee. The Shareholder and/or such Transferee
shall have the right to obtain the purchase price from the trustee (or from the
Company and/or CGW, as the case may be, following a return of the purchase price
by the trustee as hereinafter provided) upon surrender to the trustee of the
certificates evidencing such portion of the Shares or, in the event such
certificates are missing or have been stolen, an affidavit of such Shareholder
and/or such Transferee, as the case may be, to that effect together with the
agreement of such Shareholder and/or such Transferee, as the case may be, to
indemnify the Company and/or CGW, as the case may be, against any loss incurred
as a result of such missing or stolen certificates. Any portion of the purchase
price remaining in the hands of the trustee following the lapse of a two (2)
year period commencing with the date of transfer of such purchase price to the
trustee may be returned to the Company and/or CGW, as the case may be, but such
return shall not vitiate the cancellation of such portion of the Shares to which
the returned portion of the purchase price relates, and the Shareholder and/or
such Transferee shall thereafter have the right to receive such purchase price
from the Company and/or CGW, as the case may be.

                                    ARTICLE 6

                                PREEMPTIVE RIGHTS

         6.1 Preemptive Rights. Except as provided in Section 6.2 below, if
after the date hereof the Company authorizes the issuance and sale of any shares
of its equity securities or any securities containing options or rights to
acquire any shares of capital stock or any other equity securities of the
Company, the Company will first offer in writing to sell to each Shareholder a
portion of such equity securities, options or rights equal to the percentage
determined by dividing (i) the number of shares of capital stock then held by
such Shareholder by (ii) the number of shares of capital stock outstanding (on a
fully diluted basis), at the most favorable price and on the most favorable
terms as such equity securities, options or rights are to be offered to any
other person. For purposes of this Section 6.1, capital stock acquirable upon
exercise or conversion of options or rights to acquire any shares of capital
stock or any other equity securities of the Company shall be deemed outstanding
only if the applicable conversion price, exercise price or 



                                      -5-
   6

other acquisition price per share is equal to or less than the then current Fair
Value Per Share. In the event any Shareholder shall not, within ten (10)
business days after receipt of such written offer, timely exercise his rights
under this Section 6.1 to purchase a portion of such equity securities, options
or rights, or if after timely exercising such right shall fail timely to
consummate such purchase (a "Non-Purchasing Shareholder"), each other
Shareholder that has fully exercised its right under this Section 6.1 to
purchase such Shareholder's portion of such equity securities, options or rights
and who has timely consummated such purchase (a "Purchasing Shareholder") shall
have the right to purchase such Purchasing Shareholder's pro rata share
(determined among all Purchasing Shareholders on the basis of their respective
ownership of capital stock of the Company) of the portion of such equity
securities, options or rights which the Non-Purchasing Shareholder had the right
to purchase under this Article 6. Any computation of the number of shares of
equity securities, options or rights that a Shareholder has the right to
purchase under this Article 6 shall be rounded to the nearest whole share. Each
Shareholder must exercise its purchase rights within thirty (30) days after
receipt of written notice from Company describing in reasonable detail the
equity securities, options or rights being offered, the purchase price thereof,
the payment terms and such Shareholder's percentage allotment or in the case of
the purchase by a Purchasing Shareholder of a portion of the equity securities,
options or rights that a Non-Purchasing Shareholder had the right to, but did
not purchase, within forty-five (45) days after receipt of such written notice.

         The provisions of this Section 6.1 shall terminate upon the
consummation of a Public Offering (as defined in Section 9.12(e) hereof).

         6.2 Exceptions for Stock Options. Section 6.1 above and the rights of
Shareholders thereunder shall not apply to capital stock or any securities of
the Company which are convertible into or exchangeable or exerciseable for
capital stock that are issued to employees of the Company or any direct or
indirect subsidiary, either directly or upon exercise of options, rights,
warrants, grants or awards, pursuant to the terms of any stock option or stock
incentive plan adopted by the Board of Directors of the Company primarily for
the benefit of employees of the Company and its subsidiaries.

                                    ARTICLE 7

                         CO-SALE RIGHTS AND OBLIGATIONS

         7.1 Co-Sale Rights of Shareholders. In the event that CGW receives a
bona fide offer from a third party including the Company or any Affiliate
thereof (a "Proposed Purchaser") to purchase all or any portion of the shares of
capital stock of the Company owned by CGW (a "Proposed Transfer"), then each
Shareholder shall have the right, as a precondition to such Proposed Transfer,
to cause CGW to require the Proposed Purchaser to purchase such percentage of
the Shares owned by such Shareholder as such Shareholder elects, up to and
including the percentage of CGW's shares being purchased by the Proposed
Purchaser. Any Shares purchased from such Shareholder pursuant to this Section
7.1 shall be paid and contracted for at the same price per share, with the same
form of consideration and otherwise upon the same terms and conditions as the
sale by CGW.



                                      -6-
   7

         7.2 Co-Sale Obligations of Shareholders. In the event of a proposed
Sale of the Company (as defined in Section 9.12(g)) that is effected through a
sale of the capital stock of the Company, CGW shall have the right to require
such Shareholder to sell to the Proposed Purchaser in such Sale of the Company
all of its respective Shares. Any Shares purchased from a Shareholder pursuant
to this Section 7.2 shall be paid and contracted for at the same price per
share, with the same form of consideration and otherwise upon the same terms and
conditions as the sale by CGW of its shares to the Proposed Purchaser in such
Sale of the Company. If the Proposed Purchaser in any Sale of the Company is an
Affiliate of CGW, such sale may only be made at a price per each Share to each
Shareholder equal to or greater than the Fair Value Per Share determined as
provided in Section 9.12(d).

         7.3 Participation Notice. CGW shall, not less than fifteen (15) nor
more than forty-five (45) days prior to any Proposed Transfer or Sale of the
Company, notify each Shareholder in writing of any such Proposed Transfer or
Sale of the Company (the "Participation Notice"). Such Participation Notice
shall set forth: (i) the number and type of securities proposed to be
transferred (the "Transferred Securities"); (ii) the name(s) and address(es) of
the Proposed Purchaser(s); (iii) the proposed amount and all forms of
consideration and terms and conditions of payment offered by such Proposed
Purchaser; (iv) the date, time and place at which the Proposed Transfer or Sale
of the Company is to be consummated (the "Scheduled Closing"); and (v) that the
Proposed Purchaser has been informed of the co-sale rights of the Shareholders
provided for in Section 7.1 hereof and has agreed to purchase the Transferred
Securities in accordance with the terms of that Section.

         7.4 Exercise of Co-Sale Rights or Obligations. The co-sale rights
described in Section 7.1 shall be deemed to have been exercised by a Shareholder
with respect to the maximum number of Shares that can be sold by such
Stockholder unless written notice of the Non-Exercise (the "Non-Exercise
Notice") of any of such rights is delivered to CGW at least five (5) days prior
to the Scheduled Closing. The co-sale obligations described in Section 7.2 may
be exercised by delivery of a written notice (the "Exercise Notice"), at least
five (5) days prior to the Scheduled Closing, to a Shareholder.

         7.5 Miscellaneous. In the event that a Shareholder exercises his
co-sale rights pursuant to Section 7.1 hereof and the Proposed Purchaser is not
willing to purchase Shares from such Shareholder on the same terms and
conditions as specified in the Participation Notice, then CGW shall not be
permitted to transfer or otherwise dispose of any of its shares to the Proposed
Purchaser pursuant to the Proposed Transfer unless the Proposed Purchaser agrees
to purchase (i) a lesser amount of CGW's shares and (ii) a pro rata amount of
the shares of such Shareholder on the same terms and conditions as CGW's shares
are purchased. Upon exercising his respective co-sale rights pursuant to this
Article 7, a Shareholder shall be obligated until the date of the Scheduled
Closing, to transfer such number and type of securities with respect to which
such exercise has been made, to the Proposed Purchaser on the terms and
conditions stated in the Participation Notice and in accordance with the
provisions of this Article 7.

         7.6 Inapplicability of Article. Notwithstanding anything to the
contrary set forth in this Article 7, the rights and obligations arising under
this Article 7 shall not apply to: (i) the sale by CGW of shares of capital
stock of the Company pursuant to a Public Offering in which the Shareholders are
permitted to sell Shares unless the inability of the Shareholders to sell Shares
in such Public Offering is due to advice to the Company from the managing
underwriter of such offering to the effect that the inclusion in such offering
of Shares of the Shareholders would adversely affect the marketing of the
securities of the Company proposed to be sold in such offering, or (ii) any
distribution by CGW of all or any portion of the shares owned by it to its
partners.


                                    ARTICLE 8

                              TERM AND TERMINATION

Agreement, (b) the effective date of a written agreement signed by all of the
parties hereto providing for the termination of this Agreement, or (c) upon the

Public Offering (as defined in Section 9.12(e)).

         8.2 Extension of Term. This Agreement may be extended for additional
ten (10) year periods if the Company, CGW, and Shareholders who own in the
aggregate more than fifty-one percent (51%) of Shares subject to this Agreement
at the time of the extension so agree in writing.

                                    ARTICLE 9

and/or conditions of this Agreement by any party, the other parties shall, in

         9.12 Certain Definitions. The capitalized terms listed below are used
herein with the meaning thereafter ascribed:

              (a) "AFFILIATE" of any party shall mean any natural person,
         corporation, general or limited partnership, joint venture, trust,
         association, or unincorporated entity of any kind (each a "Person")
         that controls or is controlled by or under common control with such
         other party. For the purpose of this definition, "control" of a Person
         shall mean the possession, directly or indirectly, of the power to
         direct or cause the direction of its 


                                      -10-
   11

         management and policies, whether through the ownership of voting
         capital stock, by contract or otherwise, and the terms "controlled" and
         "common control" shall have correlative meanings.

              (b) "CAUSE" shall mean as to a Shareholder (i) conduct
         amounting to fraud or dishonesty against the Company; (ii) such
         Shareholder's willful misconduct intended to injure or having the
         effect of injuring the reputation, business or business relationship of
         the Company, repeated refusal to follow the reasonable directions of
         the Board of Directors of the Company, or knowing violation of law in
         the course of performance of the duties of such Shareholder's
         employment with the Company, (iii) repeated absences from work without
         a reasonable excuse without being corrected upon fifteen (15) days
         prior written notice, (iv) a conviction or plea of guilty or nolo
         contendere to a felony or a crime involving dishonesty against the
         Company; or (v) a breach or violation by such Shareholder of the terms
         of this Agreement or any other agreement to which such Shareholder and
         the Company are a party without being corrected upon fifteen (15) days
         prior written notice.

              (c) "COST" shall mean the consideration per Share paid by the
         Shareholder for such Share.

              (d) "FAIR VALUE PER SHARE" shall mean the value of a share of
         capital stock of the Company (on a fully-diluted basis) assuming the
         sale of the Company and all its subsidiaries as a whole and as a going
         concern to a willing buyer on the date with respect to which such
         determination is made (whether such sale takes the form of a sale of
         stock, a sale of assets, a merger or a consolidation). The Company
         will, within fifteen (15) days after the date with respect to which
         such determination is made, deliver to the Shareholder with respect to
         whose Shares the determination is being made a written notice setting
         forth a proposed Fair Value Per Share. If, within fifteen (15) days
         after receipt of such notice, such Shareholder does not object to the
         determination of the Fair Value Per Share set forth therein, then the
         Fair Value Per Share will be as set forth in such notice. If within
         such fifteen (15) day period such Shareholder objects to the Company's
         determination of Fair Value Per Share, the Company and such Shareholder
         will attempt to agree within fifteen (15) days following the expiration
         of such period on an appraiser to determine the Fair Value Per Share.
         If the Company and such Shareholder fail to agree on a mutually
         acceptable appraiser during such fifteen (15) day period, then the
         Company and such Shareholder will each appoint an investment banking
         firm of national reputation and such two investment banking firms will
         select a third investment banking firm of national or regional
         reputation experienced in the appraisal of businesses similar to that
         of the Company and its subsidiaries to serve as the appraiser and shall
         direct such appraiser to independently determine the Fair Value Per
         Share and to submit its determination in writing at the earliest
         practicable date, but in any event within ninety (90) days following
         the date of such appraiser's selection. The Company and the Shareholder
         shall each bear the costs of their respective investment banking firms
         for purposes of appointing an appraiser, and the costs of the third
         appraiser shall be shared equally by the Company and such Shareholder;
         provided, however, that to the extent the Fair Value Per Share



                                      -11-
   12

         determined by the appraisers ("Appraisers' Value") shall exceed the
         Fair Value Per Share proposed by the Company ("Company's Value") to the
         Shareholder pursuant to this subsection (c), the Company shall pay an
         amount of the appraisal costs of the Shareholder equal to the amount
         per share the Appraiser's Value exceeds the Company's Value, multiplied
         by the number of Shares which are the subject of the appraisal. If
         either the Company or the Shareholder fails to appoint an investment
         banking firm of national reputation within fifteen (15) days after the
         expiration of such fifteen (15) day period, then the investment banking
         firm appointed by the other party will act as the appraiser and
         determine the Fair Value Per Share. All appraisal reports will be in
         writing, will be signed by the appraiser and will be delivered to the
         Company with copies to the Shareholder. If the appraiser expresses its
         opinion as to Fair Value Per Share in terms of a range of values, the
         mean of such range shall be deemed to be the Fair Value Per Share for
         purposes of this Agreement or if such opinion expresses Fair Value Per
         Share as an absolute number, such number shall be deemed to be the Fair
         Value Per Share. The Fair Value Per Share determined as herein provided
         will be final and binding upon Company and the Shareholder.

                  (e) "PUBLIC OFFERING" shall mean one or a series of firmly
         underwritten public offerings for sale by the Company of an aggregate
         number of shares of its Common Stock for all such offerings as will,
         immediately following the completion of such offerings, constitute not
         less than twenty percent (20%) of the total shares of the Common Stock
         of the Company then issued and outstanding, which public offerings
         shall be managed by one or more underwriters that the Company, in its
         discretion, reasonably believes to have appropriate experience in
         public offerings of similar size and type, and where the aggregate
         gross proceeds to the Company from such public offerings shall be not
         less than $20,000,000.

                  (f) "REPURCHASE EVENT" means, as to a Shareholder, the
         termination of such Shareholder's employment with the Company or any
         Affiliate of the Company for any reason, other than (i) in the case of
         a "put" by such Shareholder pursuant to Section 3.1(a) above,
         termination of such employment by the Shareholder or by the Company for
         Cause, and (ii) in the case of a "call" by the Company pursuant to
         Section 3.1(b) above, termination of such employment by the Company
         without Cause.

                  (g) "SALE OF THE COMPANY" shall mean the sale of the Company
         and all of its Subsidiaries (whether by merger, share exchange,
         consolidation, sale of all of the outstanding capital stock or sale of
         substantially all of their respective assets) to any person or entity.

                  (h) "TRANSFEREE" shall mean a spouse or any child, grandchild,
         parent or spouse of any child, grandchild or parent, or any trust
         created for the benefit of any of the foregoing.
