meanings provided for therein); and

                  WHEREAS, the Company is the owner or holder of the promissory

                  WHEREAS, in order to induce the Lenders to advance to the

the Company does hereby covenant and agree as follows:

                  1.       CONVEYANCE. (a) Subject to the terms and conditions

profits, accounts, contract rights and benefits from, under and in connection
with the Assigned Documents or any collateral therefor, whether now or hereafter
due or arising, together with any and all monies, proceeds and distributions of
every kind and description now or hereafter due or payable with respect thereto

made and intended to secure the full, prompt and complete payment of the Bridge
Loan and any and all other indebtedness, obligations and liabilities of the
Company to the Agent or the Lenders now or hereafter arising under this
Agreement or the Bridge Loan Note issued pursuant to the Credit Agreement, or
any renewal or renewals, extension or extensions, or modification or
modifications of, or any substitution or substitutions for, any of the
foregoing. The indebtedness, obligations and liabilities which this instrument
is given to secure are hereinafter sometimes collectively called the
"INDEBTEDNESS".

                  2.       POWER OF ATTORNEY. The Company does hereby authorize
and empower the Agent, whether before or after an Event of Default and without
notice to or demand upon the Company, and does hereby irrevocably and duly
constitute the Agent as the Company's attorney-in-fact, to receive any and all
of the Payments, to demand and to collect any and all of the Payments by such
means and taking such actions as the Agent shall deem necessary, and to act in
all other ways with respect to the Collateral for the Company and in the
Company's place and stead, including the power to: agree to the modification,
amendment, compromise, extension or release of any of the Collateral or any
person obligated thereunder; perform any obligation of the Company hereunder;
send any Collateral to any person, entity or agent for collection, sale,
redemption or substitution without liability for loss in transit or for any act
or default of the person, entity or agent to whom such Collateral may be sent;
exercise any right, remedy, power or privilege of the holder of the Collateral;
and endorse any check or other instrument evidencing payment of any of the
Payments. The Agent shall have the right, as attorney-in-fact for the Company,
but not the obligation, to take any action hereby authorized, in the name of the
Company or in the Agent's own name, and to exercise any and all of the Company's
rights and remedies, whether available at law or in equity or otherwise, with
respect to any of the Collateral, all without releasing, impairing, affecting or
lessening the liability of the Company. The foregoing appointment of the Agent
as attorney-in-fact for the Company is coupled with an interest, cannot be
revoked by bankruptcy, insolvency, incompetency, death, dissolution or
otherwise, and shall not terminate until the Indebtedness has been paid and
satisfied in full.

                  3.       PAYMENTS PAYABLE TO THE AGENT. The Company shall
direct, instruct, demand and cause Marshall B. Hunt and Hunt Family Investments,
L.L.L.P. (collectively, the

"MAKER") and each and every other person, partnership, corporation, limited
liability company, association and other entity or organization now or hereafter
owing any of the Payments to pay any and all amounts so owed promptly and
directly to the Agent. The Company hereby represents and warrants that all
payments so made shall have the same effect in satisfaction of obligations owed
to the Company as if made directly to the Company, and the Company shall not
question or otherwise contest any such payment authorized hereby. The Company
agrees that the Agent shall apply any and all such payments to the Indebtedness
in such manner as the Agent deems appropriate.

                  4.       NOTIFICATION OF OBLIGATIONS. Upon or prior to the
execution hereof, the Company shall deliver to the Agent the originals of the
Assigned Documents, duly endorsed by the Company to the Agent if necessary to
facilitate collection or enforcement, and the Company shall notify Maker and any
other party or parties obligated on any of the Assigned Documents of the content
and existence of this Agreement and of the agreements and obligations of the
Company with respect to payment of the Payments as set forth in paragraphs 2 and
3 hereof. Any and all notices, consents and agreements required hereunder shall
be in such form and substance as the Agent may approve.

other similar laws affecting the rights of creditors generally; and (v) each of
the Assigned Documents is and will be genuine and free from forgery,
counterfeit, and all adverse liens, claims, prepayments, and defenses.

                  6.       COVENANTS OF THE COMPANY. (i) The Company will
promptly pay or cause to be paid and discharge all taxes and assessments levied
or imposed upon, or assessed against, the Collateral, and any and all liens
which may attach to the Collateral; (ii) the Company will fully and completely
perform all of the duties and obligations of the holder or the Agent of the
Assigned Documents and do all acts otherwise necessary to maintain and preserve
the Payments, it being expressly understood and agreed that the Agent neither

Collateral; (iii) the Company shall not further transfer, assign or convey the
Collateral or any portion thereof or any interest


                                      -3-

therein; and (iv) the Company shall not amend, terminate, waive, supplement or

                  7.       EVENTS OF DEFAULT. The following shall constitute
events of default ("EVENTS OF DEFAULT") by the Company hereunder:

                           (a)      Breach of Covenant. If the Company should
                  violate or breach, or should fail fully and completely to
                  observe, perform, satisfy or comply with, any of the terms,
                  covenants or conditions set forth in this Agreement; or

                           (b)      Credit Agreement. If any Event of Default
                  under (and as such term is defined in) the Credit Agreement
                  shall exist.

                  8.       REMEDIES AND POWER OF SALE. If any Event of Default
shall exist, at the Agent's option and election, without demand or notice of any
kind, the Agent may do any one or more of the following:

                           (a)      Acceleration of Indebtedness. The Agent may
                  declare all or any portion of the Indebtedness to be
                  immediately due and payable, whereupon the same shall be and
                  shall become due and payable immediately, without presentment,
                  demand, notice of demand, notice for payment, notice of
                  dishonor, protest or notice of any kind, all of which are
                  expressly waived by the Company.

                           (b)      Payments. The Agent may pay any sum or sums
                  deemed necessary or appropriate by the Agent to protect the
                  Collateral or any part thereof or the Agent's interest
                  therein. Any such sum or sums paid or incurred by the Agent
                  shall become a part of the Indebtedness, shall be payable on
                  demand, and shall bear interest at the lesser of (i) the
                  highest rate of interest payable on any of the Indebtedness,
                  or (ii) the highest rate permissible under applicable law,
                  from the date incurred until reimbursed by the Company.

                           (c)      Other Remedies. The Agent may exercise all
                  rights and remedies contained in the Credit Agreement or in
                  any of the other Financing Documents.

                           (d)      UCC Remedies. The Agent may exercise any or
                  all of the rights accruing to a secured party under this
                  Agreement, the Georgia Uniform Commercial Code and any other
                  applicable law. Any notice required to be given by the Agent
                  of a public or private sale or other disposition of the
                  Collateral, or any other intended action by the Agent, if
                  given at least ten (10) days prior to such proposed action,
                  shall constitute reasonable and fair notice to the Company of
                  any such action. The Agent shall have, without limiting the
                  generality of the foregoing or any other of its rights and
                  remedies, the right (but not the obligation)


                                      -4-
<PAGE>   5

                  to foreclose the liens and security interests created under
                  this Agreement or under any other agreement relating to the
                  Collateral by any available judicial procedure or without
                  judicial process, and full power and authority to sell,
                  assign, transfer or deliver the whole of the Collateral, or
                  any part thereof, in such order as the Agent may elect, at
                  public or private sale or sales in accordance with the Georgia
                  Uniform Commercial Code, or other applicable law or agreement,
                  and the Agent shall also have the right (but not the
                  obligation) to collect any and all Payments due under the
                  Assigned Documents. At any sale of the Collateral, the Agent
                  may, if it be the highest bidder, purchase any or all of the
                  Collateral so sold, and may apply any unpaid Indebtedness on
                  account of or in full satisfaction of the purchase price. The
                  Company hereby constitutes and appoints the Agent as the
                  Company's attorney-in-fact to sign and execute any transfer,
                  conveyance, instrument or other writing, in the name of the
                  Company or in the Agent's own name, and to do or cause to be
                  done any other act, which may be necessary for the purposes
                  herein, and the Company hereby ratifies and confirms all of
                  the acts and doings of the Agent as its attorney-in-fact
                  hereunder. The Agent's powers as attorney-in-fact hereunder
                  are coupled with an interest, cannot be revoked by bankruptcy,
                  insolvency, incompetency, death, dissolution or otherwise, and
                  shall not be exhausted until the Indebtedness has been paid
                  and satisfied in full. The proceeds of any collection or any
                  sale by the Agent hereunder of any of the Collateral shall be
                  applied, first, to the actual and reasonable costs and
                  expenses of the collection or sale and of all proceedings in
                  connection therewith, including attorneys' fees (but not to
                  exceed actual attorneys' fees incurred), if applicable, then
                  to the payment of the Indebtedness, and the remainder, if any,
                  shall be paid as provided by law. If the proceeds of any such
                  collection or sale are not sufficient to pay the Indebtedness
                  in full, the Agent shall determine, at the Agent's option and
                  in the Agent's discretion, the portions of the Indebtedness to
                  which the proceeds (after deducting therefrom the costs and
                  expenses of the collection or sale and all proceedings in
                  connection therewith) shall be applied and in what order the
                  proceeds shall be so applied. The Company shall be liable to
                  the Agent and the Lenders for any deficiency.

                  All of the foregoing rights and remedies are cumulative of and
in addition to, and not restrictive of, any right or remedy otherwise provided
for herein or provided for by statute, or now or hereafter existing at law or in
equity, and the Agent may, at the Agent's election and at the Agent's sole
discretion, exercise each and every such right and remedy concurrently or
separately.

                  9.       LIABILITY OF THE AGENT. The Agent shall not be liable
to the Company for a failure to collect any part or all of the Payments, and the
Agent may be required to account for only such sums as the Agent actually
collects. The Agent shall be under no duty or obligation whatsoever to (and the
Company waives any right it may have to require the Agent to) make or


                                      -5-
<PAGE>   6

give any presentments, demands, notices of demand, notices for payment, notices
of non-performance, protests, notices of protest, notices of dishonor or notices
of any kind in connection with any Collateral. Upon the transfer of all or any
part of the Indebtedness, the Agent may transfer all or any part of the
Collateral and shall be fully discharged thereafter from all liability and
responsibility with respect to such Collateral so transferred, and the
transferee shall be vested with all the rights and powers of the Agent hereunder
with respect to such Collateral so transferred, but with respect to any
Collateral not so transferred the Agent shall retain all rights and powers
herein given.

                  10.      CONCERNING THE AGENT.

                  The provisions of Article IX of the Credit Agreement shall
inure to the benefit of the Agent in respect of this Agreement and shall be
binding upon the parties to the Credit Agreement in such respect. In furtherance
and not in derogation of the rights, privileges and immunities of the Agent
therein set forth:

                           (a)      The Agent is authorized to take all such
                  action as is provided to be taken by it as Agent hereunder and
                  all other action reasonably incidental thereto. As to any
                  matters not expressly provided for herein (including, without
                  limitation, the timing and methods of realization upon the
                  Collateral) the Agent shall act or refrain from acting in
                  accordance with written instructions from the Required Lenders
                  or, in the absence of such instructions, in accordance with
                  its discretion.

                           (b)      The Agent shall not be responsible for the
                  existence, genuineness or value of any of the Collateral or
                  for the validity, perfection, priority or enforceability of
                  the security interests in any of the Collateral, whether
                  impaired by operation of law or by reason of any action or
                  omission to act on its part hereunder. The Agent shall have no
                  duty to ascertain or inquire as to the performance or
                  observance of any of the terms of this Agreement by the
                  Company.

                  11.      APPOINTMENT OF CO-AGENTS.

                  At any time or times, in order to comply with any legal
requirement in any jurisdiction, the Agent may appoint another bank or trust
company or one or more other persons, either to act as co-agent or co-agents,
jointly with the Agent, or to act as separate agent or agents on behalf of the
Agent and the Lenders with such power and authority as may be necessary for the
effectual operation of the provisions hereof and may be specified in the
instrument of appointment (which may, in the discretion of the Agent, include
provisions for the protection of such co-agent or separate agent similar to the
provisions of Section 10).

                  12.      TERMINATION OF SECURITY INTERESTS; RELEASE OF
COLLATERAL.

                  Upon the repayment in full of all Indebtedness secured hereby
(other than contingent indemnity or similar claims not yet asserted), the
security interests granted hereunder shall terminate and all rights to the
Collateral shall revert to the Company. At any time and from time to time prior
to such termination of the security interests granted hereunder, the Agent may
release any of the Collateral with the prior written consent of the Lenders.
Upon any such termination of such security interests or release of Collateral,
the Agent will, at the expense of the Company, execute and deliver to the
Company such documents as the Company shall reasonably request to evidence the
termination of the security interests or the release of such Collateral, as the
case may be.

                  13.      NOTICES. All notices, communications and
distributions hereunder shall be given in accordance with Section 10.03 of the
Credit Agreement.

                  14.      APPLICABLE LAW. This Agreement shall be governed by,
construed under and interpreted and enforced in accordance with the internal
laws of the State of Georgia.

                  15.      FORBEARANCE, MODIFICATION. The Agent shall not be
deemed to waive any of the Agent's rights or remedies hereunder unless such
waiver be in writing and signed by or on behalf of the Agent. No delay, omission
or forbearance by the Agent in exercising any of the Agent's rights or remedies
shall operate as a waiver of such rights or remedies, and a waiver in writing on
one occasion shall not be construed as a consent to or a waiver of any right or
any remedy on any future occasion. This Agreement shall not be modified or
amended except by a writing signed by or on behalf of the Company and the Agent.

                  16.      TIME. Time is and shall be the essence of this
Agreement and the covenants and agreements by the Company.

affect, alter, modify, diminish, impede or impair in any manner whatsoever any
