the extent permitted by Section 2.06, and reborrow pursuant to this Section
2.01.

                  SECTION 2.02. REVOLVING CREDIT NOTES. The Revolving Credit
Loans of each Lender shall be evidenced by a single Revolving Credit Note,
substantially in the form of Exhibit A (each such note, a "REVOLVING CREDIT
NOTE"), dated the Closing Date in an aggregate principal amount equal to the
amount of such Lender's Revolving Credit Commitment, duly executed and delivered
and payable to such Lender. Each Lender shall record the date and amount of each
Revolving Credit Loan made by it, whether such Revolving Credit Loan was a
Working Capital Loan or an Acquisition Loan, and the date and amount of each
payment of principal made by the Company with respect thereto, and prior to any
transfer of its Revolving Credit Note shall endorse on Schedule A thereto (or
any continuation thereof) forming a part thereof appropriate notations to
evidence the foregoing information with respect to each such Revolving Credit
Loan then outstanding; provided that the failure of any Lender to make any such
recordation or endorsement shall not affect the obligations of the Company
hereunder or under the Revolving Credit Notes. Each Lender is hereby irrevocably
authorized by the Company so to endorse its Revolving Credit Note and to attach
to and make a part of its Revolving Credit Note a continuation of any such
schedule as and when required.

                  SECTION 2.03.  INTEREST ON THE REVOLVING CREDIT LOANS.

                  (a) The Company shall pay interest on the Revolving Credit
Loans to the Lenders monthly in arrears on the first day of each calendar month
immediately succeeding the month for which such interest accrues, commencing
with the first day of the calendar month following the calendar month in which
the Closing Date occurs. In all cases accrued interest on all of the Revolving
Credit Loans shall be payable by the Company to the Lenders on the Commitment
Termination Date. Interest at the Default Rate shall be payable upon demand by
the Lenders. If any interest on any of the Revolving Credit Loans accrues or
remains payable after the Commitment Termination Date, such interest shall be
payable by the Company upon demand by the Lenders.

                  (b)(i) Except as provided in paragraph (d) below, the Company
shall be obligated to pay interest to the Lenders on the outstanding principal
balance of each Revolving Credit Loan from the date such Revolving Credit Loan
is made until such Revolving Credit Loan is repaid in full at a floating rate
per annum equal, at the Company's option, to one of: (i) the Index Rate plus
three and one-quarter percentage points (3.25%), (ii) Adjusted LIBOR plus three
and one-quarter percentage points (3.25%), or (iii) the Prime Rate plus one-half
of one percentage point (.50%).

                  (ii) On the Closing Date, continuing through the last day of
the calendar month in which the Closing Date occurs and thereafter unless the
Company shall have selected another rate or shall be deemed to have selected
another rate as provided below, the Revolving Credit Loans shall bear interest
based on the Index Rate. Thereafter, provided that no Default or Event of
Default has occurred and is then continuing, and subject to the terms and
conditions set forth herein, the Company may by written notice (or by telephonic
notice confirmed promptly in writing) delivered to the Agent not later than the
second Business Day preceding the beginning of each calendar month, elect
whether the interest payable to the Lenders for such calendar month shall be
based on the Index Rate or Adjusted LIBOR or the Prime Rate (each such notice
being referred to as a "NOTICE OF FLOATING RATE ELECTION"). In the event that
the Company shall fail to deliver any Notice of Floating Rate Election on the
date required above, provided that no Default or Event of Default shall have
occurred and be continuing, the Company shall be deemed to have delivered a
Notice of Floating Rate Election that elects to continue in effect for the
calendar month the interest rate determination mechanism in effect for the
previous month.

                  (iii) The Agent shall be entitled to rely upon and shall be
fully protected under this Agreement in relying on any Notice of Floating Rate
Election believed by the Agent to be genuine and to assume that the persons
giving the same on behalf of the Company were duly authorized unless the
responsible individual acting thereon for the Agent shall have actual notice to
the contrary.

                  (c) All computations of interest hereunder or under the other
Financing Documents for Revolving Credit Loans shall be made by the Agent on the
basis of a 360 day year for the actual number of days occurring in the period
for which such interest is payable. 


                                      -23-
<PAGE>   29

Each determination by the Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error. The Agent agrees
that it shall, upon written request of the Company (but not more frequently than
once per month), provide a written calculation in reasonable detail of the most
recent interest rate determination.

                  (d) So long as any Event of Default shall have occurred and be
continuing, the interest rate applicable to the Loans, the Reimbursement
Obligations or any other obligations of the Company or any of its Subsidiaries
under the Financing Documents may be increased by the Required Lenders, at their
option, by up to two percentage points (2%) per annum above the rate otherwise
applicable (the "DEFAULT RATE").

                  SECTION 2.04. ADVANCING REVOLVING CREDIT LOANS. Except as
provided in the last sentence of this section, each Revolving Credit Loan shall
be made on notice by the Company to the Agent, given no later than 11:00 a.m.
(New York time) on the Business Day of the proposed Revolving Credit Loan. Such
notice (each a "NOTICE OF REVOLVING CREDIT LOAN") shall be substantially in the
form of Exhibit B hereto, shall be duly completed and executed by an Authorized
Signatory, and shall specify therein the requested date and amount of such
Revolving Credit Loan, and such other information as may be required by the
Agent. Each Notice of Revolving Credit Loan shall be given in writing (by
telecopy, telex or cable) or by telephone and confirmed immediately in writing.
Notwithstanding the foregoing, no Notice of Revolving Credit Loan that requests
an Acquisition Loan shall be effective until the Agent notifies the Company that
the Agent and the Required Lenders have consented to the proposed Acquisition
after having been provided such information respecting the proposed Acquisition
as is required to be delivered pursuant to Section 3.02 and such time to review
the same as the Agent and the Required Lenders shall reasonably deem necessary.

                  SECTION 2.05. MANDATORY REPAYMENTS AND PREPAYMENTS. (a) The
Revolving Credit Commitment of each Lender shall terminate at the opening of
business on July 1, 2004 (such date and such earlier date on which the Revolving
Credit Commitments shall terminate pursuant to Section 2.08, Section 7.01 or
otherwise, the "COMMITMENT TERMINATION DATE"), and there shall become due and
the Company shall pay on the Commitment Termination Date, the entire outstanding
principal amount of each Revolving Credit Loan, together with accrued and unpaid
interest thereon to but excluding the Commitment Termination Date.

                  (b) If at any time (i) the aggregate unpaid principal balance
of the Working Capital Loans and Letter of Credit Liabilities exceeds the
Working Capital Availability, or (ii) the aggregate unpaid principal balance of
the Revolving Credit Loans and Letter of Credit Liabilities exceeds the
Revolving Credit Commitments, then, on the next succeeding Business Day, the
Company shall prepay Working Capital Loans and/or Acquisition Loans in an
aggregate principal amount equal to such excess.

                  (c) Commencing on October 1, 2000 (the "AMORTIZATION
COMMENCEMENT DATE") and continuing on each Quarterly Date thereafter, the
Company shall repay the Acquisition Loans in quarterly installments of principal
in an amount equal to the percentage of 


                                      -24-

all Acquisition Loans outstanding on the Acquisition Loan Availability

                  (d) There shall become due and payable, and the Company shall
prepay, an aggregate principal amount of the Revolving Credit Loans in the
following amounts at the following times, and in the case of any prepayment of
any Class of Revolving Credit Loans in whole, accrued and unpaid interest on the
principal amount being prepaid to but excluding the date of such payment:

         (i)      on the 90th day following the last day of each Fiscal Year,
                  beginning with the Fiscal Year ending December 31, 2000, an
                  amount equal to 50% of the Excess Cash Flow for such Fiscal
                  Year;

         (ii)     promptly upon the receipt by the Company or any of its
                  Subsidiaries of any Major Casualty Proceeds (to the extent not
                  used for replacement or restoration as provided in the
                  definition of such term), an amount equal to 100% of such
                  Major Casualty Proceeds; and

         (iii)    promptly upon receipt by the Company or any Subsidiary of the
                  proceeds of any Asset Sale after the Closing Date, an amount
                  equal to 100% of the Net Cash Proceeds of such Asset Sale.


                                      -25-
<PAGE>   31

                  Any such prepayment to be applied first to Acquisition Loans
outstanding and then to Working Capital Loans, in either case, in inverse order
of maturity.

                  SECTION 2.06. OPTIONAL PREPAYMENTS. The Company may prepay the
Revolving Credit Loans in whole or in part (in minimum principal amounts of
$100,000 or in any larger integral multiple of $10,000, or the total remaining
amount outstanding) upon at least three Business Days' prior irrevocable written
notice to the Lenders, without premium or penalty. The aggregate principal
amount of the Revolving Credit Loans designated for prepayment in any notice of
optional prepayment given pursuant to this subsection shall become due and
payable on the date fixed for prepayment as specified in such notice. Unless
otherwise directed by the Company, optional prepayments shall be applied first
to Working Capital Loans outstanding and then to Acquisition Loans, in either
case, in inverse order of maturity.

                  SECTION 2.07. APPLICATION OF PAYMENTS. Unless otherwise
provided herein, each payment or prepayment of less than all the outstanding
aggregate principal amount of the Loans shall be applied pro rata to all Loans
according to their respective outstanding principal amounts, and shall be
applied to the Class of Loan required under this Agreement or, if not so
required, as directed by the Company. The principal amount of each payment on
the Acquisition Loans pursuant to Section 2.05(d) or 2.06 shall be applied to
reduce the remaining payments required by Section 2.05(c) in inverse order of
the maturity thereof. No payment of the principal amount of the Loans pursuant
to Section 2.05(c) or 2.06 shall reduce the amount of any payment required by
Section 2.05(d). Each payment of less than all of the outstanding aggregate
principal amount of Revolving Credit Loans of any Class shall be applied by the
Lender receiving such payment, pro rata to all Revolving Credit Loans of such
Class held by such Lender in according to their respective outstanding principal
amounts.

                  SECTION 2.08. REDUCTION OF COMMITMENTS. (a) The Revolving
Credit Commitment shall reduce to the sum of the aggregate outstanding principal
amount of the Acquisition Loans plus the Working Capital Sublimit on the
Acquisition Loan Availability Termination Date, and thereafter by the amount of
each payment made or required to be made pursuant to Section 2.05 or Section
2.06 which is applied against the Acquisition Loans.

                  (b) The Company shall have the right at any time to terminate
in whole this Agreement, or from time to time, irrevocably to reduce in part the
amount of the Revolving Credit Commitments upon at least 30 days' prior written
notice to the Agent. Such notice shall be irrevocable on the part of the Company
and shall specify the effective date of such reduction or termination, whether a
termination or reduction is being made, and, in the case of any reduction, the
amount thereof shall be in an amount of Two Million Five Hundred Thousand
Dollars ($2,500,000) or an integral multiple thereof. Upon any such reduction,
the Company shall simultaneously prepay any outstanding Revolving Credit Loans
to the extent necessary so that the aggregate outstanding principal amount of
the Revolving Credit Loans and Letter of Credit Liabilities does not exceed the
amount of the Revolving Credit Commitment after giving effect to any partial
reduction thereof. The aforesaid prior notice requirement shall not apply to the
Agent's exercise of remedies under Section 7.01. In the event the Company
exercises its


                                      -26-
<PAGE>   32

rights under this paragraph to prepay the Revolving Credit Loans and terminate
this Agreement or permanently reduce the Revolving Credit Commitments, the
Company agrees that such prepayment shall be accompanied by the payment by the
Company to the Agent for the ratable account of the Lenders of all accrued and
unpaid interest and, in the case of a termination of this Agreement, all accrued
fees and other remaining Obligations hereunder. The amount of any Revolving
Credit Commitment may not be reinstated if it is reduced or if this Agreement is
terminated by the Company.

                  SECTION 2.09.  LETTERS OF CREDIT.

                  (a)   Issuance of Letters of Credit. (i) Subject to the terms
and conditions hereof and such additional terms and conditions as the LC Issuer
may require, the LC Issuer agrees to issue upon the Company's written request
therefor from time to time from the Closing Date to but not including the
Acquisition Loan Availability Termination Date, Letters of Credit for the
account of the Company.

                  (ii)  Each Letter of Credit shall (x) have an expiration date
not later than the Commitment Termination Date, (y) be used only to secure
obligations of the Company or a Subsidiary in connection with Acquisitions
permitted under Section 6.07(d), and (z) be substantially in the form of Exhibit
G hereto and otherwise in form and substance satisfactory to the Agent and the
LC Issuer in all respects.

                  (iii) The Company shall deliver to the Agent and the LC Issuer
prior to noon (New York City time) at least 3 Business Days before the requested
date of issuance of a Letter of Credit, a written request for the issuance of
such Letter of Credit (a "LETTER OF CREDIT REQUEST"), together with all of the
documents, materials and evidences required to be delivered to the Agent
pursuant to Sections 3.02 and 3.03 prior to the issuance of such Letter of
Credit. Such request shall set forth: (v) the beneficiary of the Letter of
Credit, (w) the stated amount thereof, (x) the requested issue date, (y) the
requested expiration date and (z) the drawing conditions applicable thereto. On
the requested date of issuance of such Letter of Credit the Company shall
deliver to the Agent such documents, evidences and opinions as shall be required
by Section 3.02 or 3.03.

                  (b)   Reimbursement Obligations of the Company. The Company
agrees, as a separate obligation, independent from any other obligation it may
have hereunder, to reimburse the LC Issuer for any drawing under any Letter of
Credit for the full amount of such drawing on the date of such drawing, in like
currency, without presentment, demand, protest or other formalities of any kind.
All amounts paid by the LC Issuer under any Letter of Credit not reimbursed by
the Company as provided herein shall bear interest, payable on demand, for each
day until the Company reimburses the LC Issuer therefor, at a rate per annum
equal to the sum of the Index Rate plus five and one-quarter percent (5.25%).

                  (c)   Reimbursement and Other Payments by the Company. The
obligations of the Company to reimburse the LC Issuer shall be absolute,
unconditional and irrevocable, and


                                      -27-
<PAGE>   33

shall be performed strictly in accordance with the terms of this Agreement,
under all circumstances whatsoever, including without limitation the following
circumstances:

                  (i)   any lack of validity or enforceability of any Letter of
         Credit or any related document;

                  (ii)  any amendment or waiver of or any consent to departure
         from any Letter of Credit or any related document;

                  (iii) the existence of any claim, set-off, defense or other
         right which the Company may have at any time against the beneficiary of
         any Letter of Credit (or any Person or entity for whom such beneficiary
         may be acting), the Agent, the LC Issuer, any Lender or any other
         Person or entity, whether in connection with this Agreement, any other
         Financing Document or any unrelated transaction, provided that nothing
         herein shall prevent the assertion of any such claim by separate suit
         or compulsory counterclaim;

                  (iv)  any statement or any other document presented under any
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect whatsoever;

                  (v)   payment by the LC Issuer under any Letter of Credit
         against presentation of a draft or document which does not comply with
         the terms of such Letter of Credit;

                  (vi)  any affiliation between the LC Issuer and any Lender; or

                  (vii) to the extent permitted under applicable law, any other
         circumstance or happening whatsoever, whether or not similar to any of
         the foregoing.

                  (d)   Cash Collateralization of Letter of Credit Liabilities.
Upon any optional payment in full of the Loans and termination of the Revolving
Credit Commitments pursuant to and in accordance with the terms of Section 2.08,
and upon the occurrence and during the continuance of any Event of Default, the
Company on demand of the Agent shall deposit into an account established
pursuant to lockbox arrangements satisfactory to the Agent in its sole
discretion, an amount of cash or cash equivalents equal to all Letter of Credit
Liabilities then outstanding.

                  (e)   Purchase of Participation by Lenders. Upon the issuance
of each Letter of Credit, each Lender shall be deemed to have irrevocably and
unconditionally purchased and received without recourse or warranty, an
undivided interest and participation in such Letter of Credit (including,
without limitation, all Letter of Credit Liabilities and all obligations of the
Company and the Subsidiaries thereof with respect thereto except those expressly
stated to be payable to the LC Issuer hereunder or under the other Financing
Documents) and any documents or security therefor or guaranty pertaining
thereto, equal to such Lender's Proportionate Share of such Letter of Credit.


                                      -28-
<PAGE>   34

                  (f)   Notice to Lenders. Promptly upon receipt by the LC
Issuer of any draft upon, or other notice of drawing under, any Letter of
Credit, the LC Issuer shall give the Company, the Agent and each Lender written
or telephonic notice of the amount of such draft or notice of drawing and of the
date upon which the LC Issuer proposes to honor such draft.

                  (g)   Payments by Lenders. Each Lender hereby agrees that it
shall pay to the LC Issuer prior to 2:00 p.m. (New York City time) on the date
the LC Issuer honors each drawing under a Letter of Credit such Lender's
Proportionate Share of such Letter of Credit drawing; provided, that, if the
Company should pay in full or in part any Letter of Credit drawing on the date
thereof, the obligation of each Lender to pay to the LC Issuer pursuant to this
Section its Proportionate Share of such drawing shall be reduced by an amount
equal to such Lender's Proportionate Share of such payment. Amounts paid in
excess of the net amount so owed shall promptly be refunded by the LC Issuer to
such Lender.

                  (h)   Failure to Pay by Lenders. If any Lender shall fail to
pay the amount of its participation in a Letter of Credit drawing on the date
such amount is due in accordance with subsection (g) above, the LC Issuer shall
be deemed to have advanced funds on behalf of such Lender. Each such advance
shall be secured by such Lender's participation interest, and the LC Issuer
shall be subrogated to such Lender's rights hereunder in respect thereof. Such
advance may be repaid by application to such advance of any payment that such
Lender is otherwise entitled to receive under this Agreement. Any amount not
paid by such Lender to the LC Issuer hereunder shall bear interest for each day
from the day such payment was due until such payment shall be paid in full at a
rate per annum equal to the Federal Funds Rate.

                  (i)   Reimbursement and Other Payments by the Lenders. The
obligations of each Lender to reimburse the LC Issuer shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement, under all circumstances whatsoever, including
without limitation the following circumstances:

                  (i)   any lack of validity or enforceability of any Letter of
         Credit or any related document;

                  (ii)  any amendment or waiver of or any consent to departure
         from any Letter of Credit or any related document;

                  (iii) the existence of any claim, set-off, defense or other
         right which such Lender may have at any time against the beneficiary of
         any Letter of Credit (or any Person or entity for whom such beneficiary
         may be acting), the Company, any Subsidiary of any of the Company, the
         Agent, the LC Issuer, any Lender or any other Person or entity, whether
         in connection with this Agreement, any other Financing Document or any
         unrelated transaction, provided that nothing herein shall prevent the
         assertion of any such claim by separate suit or compulsory
         counterclaim;


                                      -29-
<PAGE>   35

                  (iv)  any statement or any other document presented under any
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect whatsoever;

                  (v)   payment by the LC Issuer under any Letter of Credit
         against presentation of a draft or document which does not comply with

                  SECTION 4.02. CORPORATE AND GOVERNMENTAL AUTHORIZATION; NO
CONTRAVENTION. The execution, delivery and performance by each of the Company
and its Subsidiaries of the Financing Documents to which it is a party are
within the Company's or such Subsidiaries' corporate powers, have been duly
authorized by all necessary corporate action, require no action by or in respect
of, or filing with, any governmental body, agency or official (other than the
filing of UCC-1 financing statements, all of which have been made and are in
full force and effect) and do not contravene, or constitute a default under, any
provision of applicable law or regulation or of the certificate of incorporation
or by-laws of the Company or any of its Subsidiaries or of any agreement,
judgment, injunction, order, decree or other instrument binding upon the Company
or any of its Subsidiaries or result in the creation or imposition of any Lien
(other than the Liens created by the Security Documents) on any asset of the
Company or any of its Subsidiaries.

                  SECTION 4.03. BINDING EFFECT; LIENS OF SECURITY DOCUMENTS. (a)
Each of the Financing Documents to which the Company is a party (other than the
Notes) constitutes a valid and binding agreement of the Company, and each of the
Notes when executed and delivered in accordance with this Agreement, will
constitute valid and binding obligations of the Company, enforceable in
accordance with its respective terms, subject to bankruptcy and insolvency laws
affecting the rights of creditors generally and general principles of equity.

                  (b) Each of the Financing Documents to which any Subsidiary of
the Company is a party constitutes a valid and binding agreement of such
Subsidiary enforceable in accordance with its terms, subject to bankruptcy and
insolvency laws affecting the rights of creditors generally and general
principles of equity.

                  (c) The Security Documents create valid security interests in
the Collateral purported to be covered thereby, which security interests are and

Permitted Liens. Each of the representations and warranties made by the Company
or any Subsidiary in the Security Documents is true and correct in all material
respects.

                  (c) The projected pro forma balance sheet of the Company as of
April 30, 1998, a copy of which has been delivered to each of the Lenders,
fairly presents, in conformity with GAAP applied on a basis consistent with the
financial statements referred to in Section 4.04(a), the consolidated financial
position of the Company as of such date, adjusted to give effect (as if such
events had occurred on such date) to (i) the IPO, (ii) the making of the Loans,
(iii) the application of the proceeds therefrom as contemplated by the
Disclosure Documents and the Financing Documents, and (iv) the payment of all
legal, accounting and other fees related thereto to the extent known at the time

taxes, long-term leases or forward or long-term commitments, which are not fully
reflected on such balance sheet.

                  (e) Since December 31, 1997, there has been no material
adverse change in the business, operations, properties, prospects or condition
(financial or otherwise) of the Company or any of its Consolidated Subsidiaries.

                  SECTION 4.05. LITIGATION. There is no action, suit or
proceeding pending against, or to the knowledge of the Company threatened
against or affecting the Company or any Subsidiary before any court or
arbitrator or any governmental body, agency or official in which there is a
reasonable possibility of an adverse decision which could result in a Material
Adverse Effect or which in any manner draws into question the validity of any of
the Financing Documents. There is no action, suit or proceeding pending against,
or to the knowledge of the Company threatened against or affecting, any party to
any of the Financing Documents (other than the Company) before any court or
arbitrator or any governmental body, agency or official which in any manner
draws into question the validity of any of the Financing Documents.

                  SECTION 4.06. OWNERSHIP OF PROPERTY, LIENS. On and as of the
Closing Date, each of the Company and its Subsidiaries is the lawful owner of,
has good title to and is in lawful possession of, or has valid leasehold
interests in, all material properties and other material assets (real or
personal, tangible, intangible or mixed) purported to be owned or leased (as the
case may be) by such Person on the balance sheet referred to in Section 4.04(a),
and none of such Person's material properties or material assets is subject to
any Liens, except Permitted Liens. The Company and each Subsidiary conduct their
respective businesses without infringement or claim of infringement of any
material license, patent, trademark, trade name, service mark, copyright, trade
secret or other intellectual property right of others and there is no
infringement or claim of infringement by others of any material license, patent,
trademark, trade name, service 


                                      -36-

mark, copyright, trade secret or other intellectual property right of the
Company or any Subsidiary.

                  SECTION 4.07. NO DEFAULT. No Default or Event of Default has
occurred and is continuing and neither the Company nor any Subsidiary is in
default under or with respect to any material contract, agreement, lease or
other instrument to which it is a party or by which its property is bound or
affected which default is reasonably likely to result in a Material Adverse
Effect.

                  SECTION 4.08. NO BURDENSOME RESTRICTIONS. No contract, lease,
agreement or other instrument to which the Company or any Subsidiary is a party
or by which any of its property is bound or affected, no charge, corporate
restriction, judgment, decree or order and no provision of applicable law or
governmental regulation is reasonably likely to have a Material Adverse Effect.

                  SECTION 4.09. LABOR MATTERS. There are no strikes or other
labor disputes pending or, to the best knowledge the Company, threatened,
against the Company or any Subsidiary, which are reasonably likely to have a
Material Adverse Effect. Hours worked and payments made to the employees of the
Company and its Subsidiaries have not been in violation of the Fair Labor
Standards Act or any other applicable law dealing with such matters. All
payments due from the Company or any Subsidiary, or for which any claim may be
made against any of them, on account of wages and employee and retiree health
and welfare insurance and other benefits have been paid or accrued as a
liability on the books of such Person, as the case may be. The consummation of
the transactions contemplated by the Financing Documents will not give rise to a
right of termination or right of renegotiation on the part of any union under
any collective bargaining agreement to which it is a party or by which it is
bound.

                  SECTION 4.10. SUBSIDIARIES; OTHER EQUITY INVESTMENTS. Other
than as set forth on Schedule 4.10, the Company has no Subsidiaries. Each such
Subsidiary is, and, in the case of any additional corporate Subsidiaries formed
after the Closing Date, each of such additional corporate Subsidiaries will be
at each time that this representation is made or deemed to be made after the
Closing Date, a wholly-owned Subsidiary that is a corporation duly incorporated,
validly existing and in good standing under the laws of its jurisdiction of
incorporation, and has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted. Neither the Company nor any Subsidiary is engaged in
any joint venture or partnership with any other Person.

                  SECTION 4.11. INVESTMENT COMPANY ACT. The Company is not an
"investment company" as defined in the Investment Company Act of 1940, as
amended. The consummation of the transactions contemplated by the Financing
Documents and the Disclosure Documents do not and will not violate any provision
of such Act or any rule, regulation or order issued by the Securities and
Exchange Commission thereunder.

the Loans have been or will be used, directly or indirectly, for the purpose of
purchasing or carrying any Margin Stock, for the purpose of reducing or retiring
any indebtedness which was originally incurred to purchase or carry any Margin
Stock or for any other purpose which might cause any of the loans under this
Agreement to be considered a "purpose credit" within the meaning of Regulation
G, U or X of the Board of Governors of the Federal Reserve Board.

                  SECTION 4.13. TAXES. The Company's federal tax identification

Group has fulfilled its obligations under the minimum funding standards of ERISA
and the Code with respect to each Plan and is in compliance in all material
respects with the presently applicable provisions of ERISA and the Code with
respect to each Plan. No member of the ERISA Group has (i) sought a waiver of

intended use of the proceeds of the Notes and the Letters of Credit, except that

any liability resulting from the gross negligence or willful misconduct of such
Indemnitee. To the extent that the undertaking set forth in the immediately
preceding sentence may be unenforceable, the Company shall contribute the
maximum portion which it is permitted to pay and satisfy under applicable law to

Indemnitees or any of them. 


                                      -61-
<PAGE>   67

Without limiting the generality of any provision of this Section, to the fullest
extent permitted by law, the Company hereby waives all rights for contribution
or any other rights of recovery with respect to liabilities, losses, damages,
costs and expenses arising under or relating to Environmental Laws that it might
have by statute or otherwise against any Indemnitee.

                  SECTION 8.06. TAXES. The Company agrees to pay all
governmental assessments, charges or taxes (except income or other similar taxes
imposed on any Lender or any holder of a Note), including any interest or
penalties thereon, at any time payable or ruled to be payable in respect of the
existence, execution or delivery of this Agreement, the other Financing
Documents, or the issuance of the Notes or the Letters of Credit, and to
indemnify and hold each Lender, the LC Issuer and each and every holder of the
Notes harmless against liability in connection with any such assessments,
charges or taxes.

                  SECTION 8.07. FUNDING LOSSES. If the Company fails to borrow
any Revolving Credit Loans after notice has been given to any Lender in
accordance with Section 2.04 or make any payment when due (including pursuant to
a notice of optional prepayment), the Company shall reimburse each Lender within
15 days after demand for any resulting loss or expense incurred by it (or by an
existing or prospective participant in the related Loan), including any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or failure to
borrow; provided that such Lender shall have delivered to the Company a
certificate as to the amount of such loss or expense, which certificate shall be
conclusive in the absence of manifest error.

                  SECTION 8.08. MAXIMUM INTEREST. (a) In no event shall the
interest charged with respect to the Notes or any other obligations of the
Company under the Financing Documents exceed the maximum amount permitted under
the laws of the State of Georgia or of any other applicable jurisdiction.

                  (b) Notwithstanding anything to the contrary herein or
elsewhere, if at any time the rate of interest payable for the account of any
Lender hereunder or under any Note or other Financing Document (the "STATED
RATE") would exceed the highest rate of interest permitted under any applicable
law to be charged by such Lender (the "MAXIMUM LAWFUL RATE"), then for so long
as the Maximum Lawful Rate would be so exceeded, the rate of interest payable
for the account of such Lender shall be equal to the Maximum Lawful Rate;
provided, that if at any time thereafter the Stated Rate is less than the
Maximum Lawful Rate, the Company shall, to the extent permitted by law, continue
to pay interest for the account of such Lender at the Maximum Lawful Rate until
such time as the total interest received by such Lender is equal to the total
interest which such Lender would have received had the Stated Rate been (but for
the operation of this provision) the interest rate payable. Thereafter, the
interest rate payable for the account of such Lender shall be the Stated Rate
unless and until the Stated Rate again would exceed the Maximum Lawful Rate, in
which event this provision shall again apply.


                                      -62-
<PAGE>   68

                  (c) In no event shall the total interest received by any
Lender exceed the amount which such Lender could lawfully have received had the
interest been calculated for the full term hereof at the Maximum Lawful Rate
with respect to such Lender.

                  (d) In computing interest payable with reference to the
Maximum Lawful Rate applicable to any Lender, such interest shall be calculated
at a daily rate equal to the Maximum Lawful Rate divided by the number of days
in the year in which such calculation is made.

                  (e) If any Lender has received interest hereunder in excess of
the Maximum Lawful Rate with respect to such Lender, such excess amount shall be
applied to the reduction of the principal balance of its Loans or to other
amounts (other than interest) payable hereunder, and if no such principal or
other amounts are then outstanding, such excess or part thereof remaining shall
be paid to the Company.

by the terms thereof, together with all such powers as are reasonably incidental
thereto.

                  SECTION 9.02. AGENT AND AFFILIATES. NationsCredit shall have
the same rights and powers under the Financing Documents as any other Lender and

of the Company as if it were not the Agent hereunder.

                  SECTION 9.03. ACTION BY AGENT. The obligations of the Agent

                  SECTION 9.04. CONSULTATION WITH EXPERTS. The Agent may consult
with legal counsel (who may be counsel for the Company), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

                  SECTION 9.05. LIABILITY OF AGENT. Neither the Agent nor any of
its directors, officers, agents or employees shall be liable for any action
taken or not taken by it in connection with the Financing Documents (i) with the
consent or at the request of the Required Lenders or (ii) in the absence of its
own gross negligence or willful misconduct. Neither the Agent nor any

representation made in connection with any Financing Document or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of the Company; (iii) the satisfaction of any condition specified in
Article III, except receipt of items required to be delivered to the Agent; or

Document or any other instrument or writing furnished in connection therewith.
The Agent shall not incur any liability by acting in reliance upon any notice,
consent, certificate, statement, or other writing (which may be a bank wire,
telex, facsimile transmission or similar writing) believed by it to be genuine
or to be signed by the proper party or parties.

                  SECTION 9.06. INDEMNIFICATION. Each Lender shall, ratably in
accordance with its Revolving Credit Commitment (whether or not the Revolving
Credit Commitments have been terminated), indemnify the Agent (to the extent not
reimbursed by the Company) against any cost, expense (including counsel fees and
disbursements), claim, demand, action, loss or liability (except such as result
from the Agent's gross negligence or willful misconduct) that the Agent may
suffer or incur in connection with the Financing Documents or any action taken
or omitted by the Agent hereunder or thereunder.

                  SECTION 9.07. CREDIT DECISION. Each Lender acknowledges that
it has, independently and without reliance upon the Agent or any other Lender,
and based on such documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement. Each Lender
also acknowledges that it will, independently and without reliance upon the
Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking any action under the Financing Documents.

                  SECTION 9.08. SUCCESSOR AGENT. The Agent may resign at any
time by giving written notice thereof to the Lenders and the Company. Upon any
such resignation, the Required Lenders shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent gives notice of resignation, then the retiring Agent may, on
behalf of the Lenders, appoint a successor Agent, which shall be an institution
organized or licensed under the laws of the United States of America or of any
State thereof. Upon the acceptance of its appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Article
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent.

Agreement or the Notes may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Company and the Required Lenders
(and, if the rights or duties of the Agent are affected thereby, by the Agent);
provided that no such amendment or waiver shall, unless signed by all the
Lenders, (i) increase or decrease any Commitment of any Lender (except for a
ratable decrease in the Commitments of all Lenders) or subject any Lender to any
additional 


                                      -65-
<PAGE>   71

obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees hereunder, (iii) postpone the date fixed for any payment of principal of
any Loan pursuant to Section 2.05, or of interest on any Loan or any fees
hereunder or for any termination of any Commitment or (iv) change the percentage
of the Commitments or of the aggregate unpaid principal amount of the Notes
which shall be required for the Lenders or any of them to take any action under
this Section or any other provision of this Agreement.

                  SECTION 10.06. SUCCESSORS AND ASSIGNS; REGISTRATION. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns (including any
transferee of any Note), except that the Company may not assign or otherwise
transfer any of its rights under this Agreement without the prior written
consent of all Lenders.

                  (b) The terms and provisions of this Agreement shall inure to
the benefit of any transferee or assignee of any Note and, in the event of such
transfer or assignment, the rights and privileges herein conferred upon the
assigning Lender shall automatically extend to and be vested in such transferee
or assignee, all subject to the terms and conditions hereof. Any assignment
shall be for an equal percentage of each Class of such assignor Lender's Loans
and its Revolving Credit Commitment, and any such assignee Lender shall, upon
its registration in the Note Register referred to below, become a "Lender" for
all purposes hereunder. Upon any such assignment, the assignor Lender shall be
released from its Revolving Credit Commitment to the extent assigned to and
assumed by the assignee Lender.

                  (c) Upon any assignment of any Note(s), the assigning Lender
shall surrender its Note(s) to the Company for exchange or registration of
transfer, and the Company will promptly execute and deliver in exchange therefor
a new Note or Note(s) of the same tenor and registered in the name of the
assignor Lender (if less than all of such Lender's Notes are assigned) and the
name of the assignee Lender.

                  (d) The Company shall maintain a register (the "NOTE
REGISTER") of the Lenders and all assignee Lenders that are the holders of all
the Notes issued pursuant to this Agreement. The Company will allow any Lender
to inspect and copy such list at the Company's principal place of business
during normal business hours. Prior to the due presentment for registration of
transfer of any Note, the Company may deem and treat the Person in whose name a
Note is registered as the absolute owner of such Note for the purpose of
receiving payment of principal of and premium and interest on such Note and for
all other purposes whatsoever, and the Company shall not be affected by notice
to the contrary.

                  (e) Each Lender (including any assignee Lender at the time of
such assignment) represents that it (i) is acquiring its Notes solely for
investment purposes and not with a view toward, or for sale in connection with,
any distribution thereof, (ii) has received and reviewed such information as it
deems necessary to evaluate the merits and risks of its investment in the Notes,
(iii) is an "accredited investor" within the meaning of Rule 501(a) under the
Securities Act and (iv) has such knowledge and experience in financial and
business matters 


                                      -66-
<PAGE>   72

as to be capable of evaluating the merits and risks of its investment in the
Notes, including a complete loss of its investment.

                  (f) Each Lender understands that the Notes are being offered
only in a transaction not involving any public offering within the meaning of
the Securities Act, and that, if in the future such Lender decides to resell,
pledge or otherwise transfer any of the Notes, such Notes may be resold, pledged
or transferred only (i) to the Company, (ii) to a person who such Lender
reasonably believes is a qualified institutional buyer that purchases for its
own account or for the account of a qualified institutional buyer to whom notice
is given that such resale, pledge or transfer is being made in reliance on Rule
144A under the Securities Act or (iii) pursuant to an exemption from
registration under the Securities Act.

                  (g) Each Lender understands that the Notes will, unless
otherwise agreed by the Company and the holder thereof, bear a legend to the
following effect:

         THIS SECURITY IS NOT BEING REGISTERED UNDER THE SECURITIES ACT OF 1933,
         AS AMENDED (THE "SECURITIES ACT"). THE HOLDER HEREOF, BY PURCHASING
         THIS SECURITY, AGREES FOR THE BENEFIT OF THE ISSUER THAT THIS SECURITY
         MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) TO THE
         COMPANY, (2) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A
         QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE
         SECURITIES ACT PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A
         QUALIFIED INSTITUTIONAL BUYER THAT IS AWARE THAT THE RESALE, PLEDGE OR
         OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A OR (3) PURSUANT
         TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

                  (h) If any Note becomes mutilated and is surrendered by the
Lender with respect thereto to the Company, or if any Lender claims that any of
its Notes has been lost, destroyed or wrongfully taken, the Company shall
execute and deliver to such Lender a replacement Note, upon the affidavit of
such Lender attesting to such loss, destruction or wrongful taking with respect
to such Note and such lost, destroyed, mutilated, surrendered or wrongfully
taken Note shall be deemed to be canceled for all purposes hereof. Such
affidavit shall be accepted as satisfactory evidence of the loss, wrongful
taking or destruction thereof and no indemnity shall be required as a condition
of the execution and delivery of a replacement Note. Any costs and expenses of
the Company in replacing any such Note shall be for the account of such Lender.

                  SECTION 10.07. COLLATERAL. Each of the Lenders represents to
the Agent and each of the other Lenders that it in good faith is not relying
upon any Margin Stock as collateral in the extension or maintenance of the
credit provided for in this Agreement.

inaction by the Agent or any Lender or any agent or attorney of the Agent or any
Lender in connection with this Agreement or any other Financing Document or the

of the Agent or any Lender or a defense to payment of any obligations of the
Company under this Agreement or any other Financing Document for any reason,
including commission of a tort or violation of any contractual duty or duty

(10) days after the Company has knowledge, or with the exercise of reasonable
diligence could have had knowledge, of any such action or inaction), the Company
shall not assert, and the Company shall be deemed to have waived, any claim or
defense arising therefrom to the extent that the Agent or any Lender could have
mitigated such claim or defense after receipt of such notice.

                  (A) The Company has good and marketable title to all of the
Collateral, free and clear of any Liens other than the Permitted Liens. The
Company has taken all actions necessary under the UCC to perfect its interest in
any Accounts purchased or otherwise acquired by or granted to it, as against its
assignors and grantors and creditors of its assignors and grantors.

the Agent from enforcing any of the terms of this Agreement or which would limit
the Agent in any such enforcement. Other than financing statements or other
similar or equivalent documents or instruments with respect to the Security
Interests and Permitted Liens, no financing statement, mortgage, security
agreement or similar or equivalent document or instrument covering all or any
part of the Collateral is on file or of record in any jurisdiction in which such
filing or recording would be effective to perfect a Lien on such Collateral. No
Collateral is in the possession of any Person (other than the Company) asserting
any claim thereto or security interest therein, except that the Agent or its
designee may have possession of Collateral as contemplated hereby.

the form specified in Schedule 6 to the Perfection Certificate shall have been
filed in the offices specified in the Perfection Certificate, the Security
Interests shall constitute perfected security interests in the Collateral
(except Inventory in transit) to the extent that a security interest therein may
be 


                                      F-4

perfected by filing pursuant to the UCC, prior to all other Liens and rights of
others therein except for the Permitted Liens.

the requirements of the Credit Agreement.

                  (F) Exhibit A (as updated by the Company from time to time
with the consent of the Agent, such consent not to be unreasonably withheld)
lists each bank account, money market account and investment account of the
Company.

SECTION 3.  THE SECURITY INTERESTS.

                  (A) In order to secure the full and punctual payment and
performance of the Secured Obligations in accordance with the terms thereof, the
Company hereby grants to the Agent for the ratable benefit of the Secured
Parties a continuing security interest in and to all of the following property

         Section 5(D) or otherwise and other monies and property of any kind of
         the Company in the possession or under the control of the Agent;

                  (8) All books and records (including customer lists, credit

<PAGE>   88

                  (9)  Insurance policies of the Company; and

                  (10) All Proceeds of all or any of the Collateral described in
         Clauses 1 through 9 hereof.

                  (B) The Security Interests are granted as security only and
shall not subject any Secured Party to, or transfer or in any way affect or
modify, any obligation or liability of the Company with respect to any of the
Collateral or any transaction in connection therewith.

thereof and delivered an opinion of counsel with respect thereto in accordance
with Section 4(L). The Company will not change the location of (i) its chief
executive office or chief place of business or (ii) the locations where it keeps
or holds any Collateral or any records relating thereto from the applicable
location described in the Perfection Certificate unless it shall have given the
Agent prior notice thereof and delivered an opinion of counsel with respect
thereto in accordance with Section 4(L). The Company shall not in any event
change the location of any Collateral without the prior written consent of the
Agent if such change would cause the Security Interests in such Collateral to
lapse or cease to be perfected.

                  (B) The Company shall not in any event change the location of
any Collateral without the prior written consent of the Agent if such change
would cause the Security Interests to lapse or cease to be perfected.

                  (C) To the extent permitted under applicable law, the Company
will, from time to time, at its expense, execute, deliver, file and record any
statement, assignment, instrument, document, agreement or other paper and take
any other action (including any filings of financing or continuation statements
under the UCC) that from time to time may be necessary or desirable, or that the
Agent may request, in order to create, preserve, perfect, confirm or validate
the Security Interests or to enable the Secured Parties to obtain the full
benefits of this Agreement, or to enable the Agent to exercise and enforce any
of its rights, powers and remedies hereunder with respect to any of the
Collateral. To the extent permitted by applicable law, the Company hereby
authorizes the Agent, and appoints the Agent as its true and lawful attorney
(with full power of substitution, in the name of the Company, the Secured
Parties or otherwise, for the sole use and benefit of the Secured Parties), to
execute and file financing statements or continuation statements without the
Company's signature appearing thereon. The Company agrees that a carbon,
photographic, photostatic or other reproduction of this Agreement or of a
financing


                                      F-6
<PAGE>   89

statement is sufficient as a financing statement. The Company shall pay the
costs of, or incidental to, any recording or filing of any financing or
continuation statements concerning the Collateral.

                  (D) If any Collateral is at any time in the possession or
control of any warehouseman, bailee or any of the Company's agents or
processors, the Company shall notify such warehouseman, bailee, agent or
processor of the Security Interests created hereby and to hold all such
Collateral for the Agent's account subject to the Agent's instructions.

                  (E) The Company shall keep full and accurate books and records
relating to the Collateral, and stamp or otherwise mark such books and records
in such manner as the Agent may reasonably require in order to reflect the
Security Interests.

                  (F) The Company will immediately deliver and pledge each
Instrument to the Agent, appropriately endorsed to the Agent, provided that so
long as no Event of Default shall have occurred and be continuing, the Company
may retain for collection in the ordinary course any Instruments (other than
checks and drafts constituting payments in respect of Accounts, as to which the
provisions of Section 5(B) shall apply) received by it in the ordinary course of
business and the Agent shall, promptly upon request of the Company, make
appropriate arrangements for making any other Instrument pledged by the Company
available to it for purposes of presentation, collection or renewal (any such
arrangement to be effected, to the extent deemed appropriate to the Agent,
against trust receipt or like document).

                  (G) The Company shall use its best efforts to cause to be
collected from its account debtors, as and when due, any and all amounts owing
under or on account of each Account (including Accounts which are delinquent,
such Accounts to be collected in accordance with lawful collection procedures
and the Company's customary practices) and shall apply forthwith upon receipt
thereof all such amounts as are so collected to the outstanding balance of such
Account. Subject to the rights of the Secured Parties hereunder upon the
occurrence and during the continuance of an Event of Default, the Company may
allow in the ordinary course of business as adjustments to amounts owing under
its Accounts (i) an extension or renewal of the time or times of payment, or
settlement for less than the total unpaid balance, which the Company finds
appropriate in accordance with sound business judgment unless such extension,
renewal or settlement results in causing such Account to not be an Eligible
Receivable and thereby causes the aggregate unpaid balance of Working Capital
Loans to exceed the Borrowing Base and (ii) a refund or credit due as a result
of returned or damaged merchandise or as a discount for prompt payment, all in
accordance with the Company's ordinary course of business consistent with its
historical collection practices. The costs and expenses (including attorney's




                                      F-7
<PAGE>   90

fees) of collection, whether incurred by the Company or the Agent, shall be
borne by the Company.

                  (H) Upon the occurrence and during the continuance of any
Event of Default, upon request of the Required Lenders through the Agent, to the
extent permitted by applicable law the Company will promptly notify (and the
Company hereby authorizes the Agent so to notify) each account debtor in respect
of any Account or Instrument that such Collateral has been assigned to the Agent
hereunder, and that any payments due or to become due in respect of such
Collateral are to be made directly to the Agent or its designee.

                  (I) The Company shall not permit any items of Equipment to
become a fixture to real estate (unless the Agent has a first priority Lien
thereon) or an accession to other personal property.

                  (J) Without the prior written consent of the Agent and except
in the ordinary course of business, the Company will not sell, lease, exchange,
assign or otherwise dispose of, or grant any option with respect to, any
Collateral except, subject to the rights of the Secured Parties hereunder if an
Event of Default shall have occurred and be continuing, as permitted under the
Credit Agreement including Section 8.06, whereupon, in the case of such a sale
or exchange, the Security Interests created hereby in such item (but not in any
Proceeds arising from such sale or exchange) shall cease immediately without any
further action on the part of the Agent, except the execution of UCC-3
termination statements.

                  (K) The Company will, promptly upon request, provide to the
Agent all information and evidence it may reasonably request concerning the
Collateral to enable the Agent to enforce the provisions of this Agreement.

                  (L) Not more than six months nor less than 30 days prior to
each date on which the Company proposes to take any action contemplated by
Section 4(A), the Company shall give notice to the Agent of such proposed
action, and, at the Company's cost and expense, cause to be delivered to the
Secured Parties with such notice, an opinion of counsel, reasonably satisfactory
to the Agent and substantially in the form of Exhibit C to the effect that all
financing statements and amendments or supplements thereto, continuation
statements and other documents required to be recorded or filed in order to
perfect and protect the Security Interests have been filed in each filing office
necessary for such purpose and that all filing fees and taxes, if any, payable
in connection with such filings have been paid in full.

                  (M) The Company shall not open or maintain any bank account,
money market account or investment account unless such account is first listed
on Exhibit A (as updated by the 


                                      F-8
<PAGE>   91

Company from time to time with the consent of the Agent, such consent not to be
unreasonably withheld) and is subject to a Lockbox Agreement.

                  (N) The Company shall (i) upon the occurrence of an Event of
Default and (ii) within 10 days after the aggregate value of all Equipment
consisting of motor vehicles, trucks and trailers owned by the Company and its
Subsidiaries shall exceed $150,000, deliver to the Agent any and all
certificates of title, applications for title or similar evidence of ownership
of such Equipment and shall cause the Agent to be named as lienholder on any
such certificate of title or other evidence of ownership.

SECTION 5.  LOCKBOX ACCOUNT AND INSURANCE ACCOUNT.

                  (A) On the Closing Date, the Company shall deliver to the
Agent for each account listed on Exhibit A hereto (each a "LOCKBOX ACCOUNT"), a
lockbox agreement substantially in form of Exhibit D hereto or in such other
form as shall be satisfactory to the Agent (each a "LOCKBOX AGREEMENT"), which
shall establish such account in the name "NationsCredit Commercial Corporation,
as Agent", and under the exclusive control of the Agent. From and after the
Closing Date, there shall be deposited from time to time into the Lockbox
Accounts the cash Proceeds of the Collateral required to be delivered to the
Agent pursuant to subsection (B) of this Section 5 or any other provision of
this Agreement. Any income received with respect to the balance from time to
time standing to the credit of each Lockbox Account, including any interest or
capital gains on Liquid Investments, may be withdrawn from such Lockbox Account
in accordance with subsection (C) below. All right, title and interest in and to
the cash amounts on deposit from time to time in the Lockbox Accounts together
with any Liquid Investments from time to time made pursuant to subsection (D) of
this Section shall vest in the Agent (pursuant to the Lockbox Agreement for each
Lockbox Account), shall constitute part of the Collateral hereunder and shall
not constitute payment of the Secured Obligations until applied thereto as
hereinafter provided.

                  (B) The Company shall instruct all account debtors and other
Persons obligated in respect of all Accounts, to make all payments in respect of
such Accounts and shall use its reasonable best efforts to cause such account
debtors and other Persons to remit all such payments directly to a Lockbox
Account (if paid by wire transfer). In addition to the foregoing, the Company
agrees that if the proceeds of any Collateral hereunder (including the payments
made in respect of Accounts) shall be received by it, the Company shall as
promptly as possible deposit such proceeds into a Lockbox Account. Until so
deposited, all such proceeds shall be held in trust by the Company for and as
the property of the Secured Parties and shall not be commingled with any other
funds or property of the Company.



                                      F-9
<PAGE>   92

                  (C) The balance from time to time standing to the credit of
the Lockbox Accounts shall, except upon the occurrence and continuation of an
Event of Default, be distributed to the Company in accordance with the
provisions of each Lockbox Agreement. If immediately available cash on deposit
in the Lockbox Accounts is not sufficient to make any distribution to the
Company referred to in the previous sentence of this Section 5(C), the Agent
shall cause to be liquidated as promptly as practicable Liquid Investments in
the Lockbox Accounts designated by the Company as required to obtain sufficient
cash to make such distribution and, notwithstanding any other provision of this
Section 5, such distribution shall not be made until such liquidation has taken
place. Upon the occurrence and continuation of an Event of Default, the Agent
shall, if so instructed by the Required Lenders, apply or cause to be applied
(subject to collection) any or all of the balance from time to time standing to
the credit of any Lockbox Accounts in the manner specified in Section 9.

                  (D) Amounts on deposit in the Lockbox Accounts shall be
invested and re-invested from time to time in such Liquid Investments as the
Company shall determine, which Liquid Investments shall be held in the name and
be under the control of the Agent; provided that, if an Event of Default has
occurred and is continuing, the Agent shall, if instructed by the Required
Lenders, cause such Liquid Investments to be liquidated and apply or cause to be
applied the proceeds thereof to the payment of the Secured Obligations in the
manner specified in Section 9. For this purpose, "Liquid Investments" means
Temporary Cash Investments; provided that (i) each Liquid Investment shall
mature within 30 days after it is acquired by the Agent and (ii) in order to
provide the Agent, for the benefit of the Secured Parties, with a perfected
security interest therein, each Liquid Investment shall be either:

                  (i)  evidenced by negotiable certificates or instruments, or
         if non-negotiable then issued in the name of the Agent, which (together
         with any appropriate instruments of transfer) are delivered to, and
         held by, the Agent or an agent thereof (which shall not be the Company
         or any of its Affiliates) in the State of Georgia; or

                  (ii) in book-entry form and issued by the United States and
         subject to pledge under applicable state law and Treasury regulations
         and as to which (in the opinion of counsel to the Agent) appropriate
         measures shall have been taken for perfection of the Security
         Interests.

         virtue thereof,

                  (ii)  to settle, compromise, compound, prosecute or defend any
         action or proceeding with respect thereto,

                  (iii) to sell, transfer, assign or otherwise deal in or with
         the same or the proceeds or avails thereof, as fully and effectually as
         if the Agent were the absolute owner thereof, and

                  (iv)  to extend the time of payment of any or all thereof and
         to make any allowance and other adjustments with reference thereto;

provided that the Agent shall give the Company not less than ten days' prior
written notice of the time and place of any sale or other intended disposition
of any of the Collateral, except any Collateral which is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market. The Company agrees that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC.

SECTION 7.  REMEDIES UPON EVENT OF DEFAULT.

                  (A) If any Event of Default has occurred and is continuing,
the Agent may exercise on behalf of the Secured Parties all rights of a secured
party under the UCC (whether or not in effect in the jurisdiction where such
rights are exercised) and, in addition, the Agent may, without being required to
give any notice, except as herein or in the Credit Agreement or any other
Financing Document provided or as may be required by mandatory provisions of
law, (i) withdraw all cash and Liquid Investments in the Collateral Accounts and
apply such cash and Liquid Investments and other cash, if any, then held by it
as Collateral as specified in Section 9 and (ii) if there shall be no such cash
or Liquid Investments or if such cash and Liquid Investments shall be
insufficient to pay all the Secured Obligations in full, sell the Collateral or


                                      F-11
<PAGE>   94

any part thereof at public or private sale, for cash, upon credit or for future
delivery, and at such price or prices as the Agent may deem satisfactory. The
Agent or any other Secured Party may be the purchaser of any or all of the
Collateral so sold at any public sale (or, if the Collateral is of a type
customarily sold in a recognized market or is of a type which is the subject of
widely distributed standard price quotations, at any private sale). The Company
will execute and deliver such documents and take such other action as the Agent
deems necessary or advisable in order that any such sale may be made in
compliance with law. Upon any such sale the Agent shall have the right to
deliver, assign and transfer to the purchaser thereof the Collateral so sold.
Each purchaser at any such sale shall hold the Collateral so sold to it
absolutely and free from any claim or right of whatsoever kind, including any
equity or right of redemption of the Company which may be waived, and the
Company, to the extent permitted by law, hereby specifically waives all rights
of redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted. The notice (if any) of such sale required by
Section 6 shall (1) in case of a public sale, state the time and place fixed for
such sale, and (2) in the case of a private sale, state the day after which such
sale may be consummated. Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the Agent
may fix in the notice of such sale. At any such sale the Collateral may be sold
in one lot as an entirety or in separate parcels, as the Agent may determine.
The Agent shall not be obligated to make any such sale pursuant to any such
notice. The Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for the sale, and such sale may be made at any time
or place to which the same may be so adjourned. In case of any sale of all or
any part of the Collateral on credit or for future delivery, the Collateral so
sold may be retained by the Agent until the selling price is paid by the
purchaser thereof, but the Agent shall not incur any liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold and, in
case of any such failure, such Collateral may again be sold upon like notice.
The Agent, instead of exercising the power of sale herein conferred upon it, may
proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction.

                  (B) For the purpose of enforcing any and all rights and
remedies under this Agreement the Agent may (i) require the Company to, and the
Company agrees that it will, at its expense and upon the request of the Agent,
forthwith assemble all or any part of the Collateral as directed by the Agent
and make it available at a place designated by the Agent which is, in its
opinion, reasonably convenient to the Agent and the Company, whether at the
premises of the Company or otherwise, (ii) to the extent permitted by applicable
law, enter, with or without process of law and without breach of the peace, any
premise where any of the Collateral is or may be located, and without charge or
liability to it seize and remove such Collateral from such premises, (iii) have
access to and use the Company's books and records relating to the Collateral


                                      F-12
<PAGE>   95

and (iv) prior to the disposition of the Collateral, store or transfer it
without charge in or by means of any storage or transportation facility owned or
leased by the Company, process, repair or recondition it or otherwise prepare it
for disposition in any manner and to the extent the Agent deems appropriate and,
in connection with such preparation and disposition, use without charge any
trademark, trade name, copyright, patent or technical process used by the
Company.

SECTION 8.  LIMITATION ON DUTY OF AGENT IN RESPECT OF COLLATERAL.

                  Beyond the exercise of reasonable care in the custody thereof,
the Agent shall have no duty as to any Collateral in its possession or control
or in the possession or control of any agent or bailee or any income thereon or
as to the preservation of rights against prior parties or any other rights
pertaining thereto. The Agent shall be deemed to have exercised reasonable care
in the custody of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which it accords its own property, and
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any warehouseman, carrier, forwarding agency, consignee or other
agent or bailee selected by the Agent in good faith.

SECTION 9.  APPLICATION OF PROCEEDS.

                  Upon the occurrence and during the continuance of an Event of
Default, the proceeds of any sale of, or other realization upon, all or any part
of the Collateral and any cash held in the Collateral Accounts shall be applied
by the Agent in the following order of priorities:

                  first, to payment of the expenses of such sale or other
         realization, including reasonable compensation to agents and counsel
         for the Agent, and all expenses, liabilities and advances incurred or
         made by the Agent in connection therewith, and any other unreimbursed
         expenses for which the Agent or any other Secured Party is to be
         reimbursed pursuant to Section 10.04 of the Credit Agreement or Section
         12 hereof and unpaid fees owing to the Agent under the Credit
         Agreement;

                  second, to the ratable payment of accrued but unpaid interest
         on the Secured Obligations in accordance with the provisions of the
         Credit Agreement;

                  third, to the ratable payment of unpaid principal of the
         Secured Obligations;

                  fourth, to the ratable payment of all other Secured
         Obligations, until all Secured Obligations shall have been paid in
         full; and


                                      F-13
<PAGE>   96

                  finally, to payment to the Company or its successors or
         assigns, or as a court of competent jurisdiction may direct, of any
         surplus then remaining from such proceeds.

The Agent may make distributions hereunder in cash or in kind or, on a ratable
basis, in any combination thereof.

SECTION 10.  CONCERNING THE AGENT.

                  The provisions of Section 10.05 and Article XI 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 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.

SECTION 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
Secured Parties 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).



                                      F-14
<PAGE>   97

SECTION 12.  EXPENSES.

                  In the event that the Company fails to comply with the
provisions of the Credit Agreement or this Agreement, such that the value of any
Collateral or the validity, perfection, rank or value of any Security Interest
is thereby diminished or potentially diminished or put at risk, the Agent if
requested by the Required Lenders may, but shall not be required to, effect such
compliance on behalf of the Company, and the Company shall reimburse the Agent
for the costs thereof on demand. All insurance expenses and all expenses of
protecting, storing, warehousing, appraising, insuring, handling, maintaining,
and shipping the Collateral, any and all excise, property, sales, and use taxes
imposed by any state, federal, or local authority on any of the Collateral, or
in respect of periodic appraisals and inspections of the Collateral to the
extent the same may be requested by the Required Lenders from time to time as
provided in the Credit Agreement, or in respect of the sale or other disposition
thereof shall be borne and paid by the Company; and if the Company fails to
promptly pay any portion thereof when due, the Agent or any other Secured Party
may, at its option, but shall not be required to, pay the same and charge the
Company's account therefor, and the Company agrees to reimburse the Agent or
such other Secured Party therefor on demand. All sums so paid or incurred by the
Agent or any other Secured Party for any of the foregoing and any and all other
sums for which the Company may become liable hereunder and all costs and
expenses (including attorneys' fees, legal expenses and court costs) reasonably
incurred by the Agent or any other Secured Party in enforcing or protecting the
Security Interests or any of their rights or remedies under this Agreement,
shall, together with interest thereon until paid as provided in Section 10.03 of
the Credit Agreement, be additional Secured Obligations hereunder.

SECTION 13.  TERMINATION OF SECURITY INTERESTS; RELEASE OF COLLATERAL.

                  Upon the repayment in full of all Secured Obligations (other
than contingent indemnity or similar claims not yet asserted) and the
termination of the Commitment under the Credit Agreement, the Security Interests
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, the Agent may release any of the Collateral with the prior written
consent of the Required Lenders. Upon any such termination of the Security
Interests or release of Collateral, the Agent will, at the expense of the
Company, promptly 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.

SECTION 14.  NOTICES.



                                      F-15
<PAGE>   98

                  All notices, communications and distributions hereunder shall
be given in accordance with Section 12.03 of the Credit Agreement.

SECTION 15.  WAIVERS, NON-EXCLUSIVE REMEDIES.

                  No failure on the part of the Agent to exercise, and no delay
in exercising and no course of dealing with respect to, any right under this
Agreement shall operate as a waiver thereof; nor shall any single or partial
exercise by the Agent or any Secured Party of any right under the Credit
Agreement, any of the other Financing Documents or this Agreement preclude any
other or further exercise thereof or the exercise of any other right. The rights
in this Agreement, the Credit Agreement and the other Financing Documents are
cumulative and are not exclusive of any other remedies provided by law.

SECTION 16.  SUCCESSORS AND ASSIGNS.

                  This Agreement is for the benefit of the Agent and the Secured
Parties and their successors and assigns, and in the event of an assignment of
all or any of the Secured Obligations, the rights hereunder, to the extent
applicable to the indebtedness so assigned, may be transferred with such
indebtedness. This Agreement shall be binding on the Company and its successors
and assigns.

SECTION 17.  CHANGES IN WRITING.

                  Neither this Agreement nor any provision hereof may be
changed, waived, discharged or terminated orally, but only in writing signed by
the Company and the Agent with the consent of the Required Lenders.

SECTION 18.  GEORGIA LAW.

                  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF GEORGIA (WITHOUT REFERENCE TO PRINCIPLES OR
CONFLICTS OF LAW), EXCEPT AS OTHERWISE REQUIRED BY MANDATORY PROVISIONS OF LAW
AND EXCEPT TO THE EXTENT THAT REMEDIES PROVIDED BY THE LAWS OF ANY JURISDICTION
OTHER THAN GEORGIA ARE GOVERNED BY THE LAWS OF SUCH JURISDICTION.

SECTION 19.  SEVERABILITY.

                  If any provision hereof is invalid or unenforceable in any
jurisdiction, then, to the fullest extent permitted by law, (i) the other
provisions hereof shall remain in full force and effect in such jurisdiction and
shall be liberally construed in favor of the Agent and the other Secured Parties
in order to carry out the intentions of the parties hereto as nearly as may be
possible; and (ii) the invalidity or unenforceability of any provision hereof in
any jurisdiction shall not affect the validity or enforceability of such
provision in any other jurisdiction.

SECTION 20.  COUNTERPARTS.

                  This Agreement may be signed in any number of counterparts,
each of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument.

listed in Schedule 7 to the Perfection Certificate (the "FILING JURISDICTIONS"),
which are all of the offices in which filings are required to perfect the
Security Interest, to the extent the Security Interest may be perfected by
filing under the UCC, and no further filing or recording of any document or
instrument or other action will be required so to perfect the Security Interest
in the Collateral in which a security interest may be perfected by filing a
financing statement under the UCC, except that (i) continuation statements with
respect to each Financing Statement must be filed in accordance with the UCC;
(ii) additional filings may be necessary if the Company changes its name,
identity or corporate structure or the jurisdiction in which its places of
business, its chief executive office or the Collateral are located; and (iii) we
express no opinion on the perfection of, or need for further filing or recording
to perfect, the Security Interest in goods now or hereafter located in any
jurisdiction other than the Filing Jurisdictions.

                  3. There are

                  (i)  Based on [describe search reports], as of that date of
         such reports, no UCC financing statements which name the Company as
         debtor or seller and cover any of the Collateral, other than the
         Financing Statements, [and the financing statements with respect to
         Permitted Liens annexed as Schedule 5(A) to the Perfection
         Certificate], listed in the available records in the UCC filing offices
         set forth in paragraphs 2 and 3 of the Perfection Certificate, which,
         based on the information provided to us as to the location of the
         Collateral, the Company and its books and records, include all of the
         offices prescribed under the UCC as the offices in which filings should
         have been made to perfect security interests in the Collateral; and

                  (ii) Based on [describe search reports], as of that date of
         such reports, no notices of the filing of any federal tax lien (filed
         pursuant to Section 6323 of the Internal 


                                      F-1
<PAGE>   107

         Revenue Code) or any lien of the Pension Benefit Guaranty Corporation
         (filed pursuant to Section 4068 of ERISA) covering any of the
         Collateral listed in the available records in the [UCC filing office in
         state of Company's chief executive office], which is the only office
         having files which must be searched in order to fully determine the
         existence of notices of the filing of federal tax liens (filed pursuant
         to Section 6323 of the Internal Revenue Code) on the Collateral and
         liens of the Pension Benefit Guaranty Corporation (filed pursuant to
         Section 4068 of ERISA) on the Collateral.

                  4. The Security Interest validly secures the payment of all
future Loans made by the Lenders to the Company, whether or not at the time such
Loans are made an Event of Default or other event not within the control of the
Lenders has relieved or may relieve the Lenders from their obligations to make
such Loans, and is perfected to the extent set forth in paragraph 2 above with
respect to such future Loans. Insofar as the priority thereof is governed by the
UCC, the Security Interest has the same priority with respect to such future
Loans as it does with respect to Loans made on the date hereof.

                  Such opinion may contain such assumptions, qualifications and
limitations as the opinion of counsel for the Company delivered in connection
with the making of the initial Loan under the Credit Agreement.

SECTION 2.  REPRESENTATIONS AND WARRANTIES.

                  Company represents and warrants as follows:

                  (A) Title to Pledged Securities. Company owns all of the
Pledged Securities, free and clear of any Liens other than the Security
Interests. All of the Pledged Stock has been duly authorized and validly issued,
and is fully paid and non-assessable, and is subject to no options to purchase
or similar rights of any Person. Company is not and will not become a party to
or otherwise bound by any agreement, other than this Agreement, which restricts
in any manner the rights of any present or future holder of any of the Pledged
Securities with respect thereto.

                  (B) Validity, Perfection and Priority of Security Interests.
Upon the delivery of certificates representing the Pledged Stock to the Agent in
accordance with Section 4 hereof, the Agent will have valid and perfected
security interests in the Collateral subject to no prior Lien. No registration,
recordation or filing with any governmental body, agency or official is


                                      G-2
<PAGE>   113

required in connection with the execution or delivery of this Agreement or
necessary for the validity or enforceability hereof or for the perfection or
enforcement of the Security Interests. Neither the Company nor the Subsidiaries
has performed or will perform any acts which might prevent the Agent from
enforcing any of the terms and conditions of this Agreement or which would limit
the Agent in any such enforcement.

                  (C) UCC Filing Locations. The chief executive office of the
Company is located at its address set forth on the signature pages of the Credit
Agreement. Under the Uniform Commercial Code as in effect in the state in which
such office is located, no local filing is required to perfect a security
interest in collateral consisting of general intangibles.

SECTION 3.  THE SECURITY INTERESTS.

                  In order to secure the full and punctual payment and
performance of the Secured Obligations in accordance with the terms thereof, and
to secure the performance of all the obligations of the Company hereunder:

                  (A) The Company hereby assigns and pledges to and with the
Agent for the benefit of the Secured Parties and grants to the Agent for the
benefit of the Secured Parties a security interest in the Pledged Securities,
and all of its rights and privileges with respect to the Pledged Securities, and
all income and profits thereon, and all interest, dividends and other payments
and distributions with respect thereto, and all proceeds of the foregoing (the
"COLLATERAL"). Contemporaneously with the execution and delivery hereof, the
Company is delivering the certificates representing the Subsidiaries Shares in
pledge hereunder.

                  (B) In the event that the Subsidiaries at any time issue any
additional or substitute shares of capital stock of any class or owes any other
Debt to the Company, the Company will immediately pledge and deposit with the
Agent certificates representing all such shares or an instrument evidencing such
other Debt as additional security for the Secured Obligations. All such shares
and instruments constitute Pledged Securities and are subject to all provisions
of this Agreement.

                  (C) The Security Interests are granted as security only and
shall not subject any Secured Party to, or transfer or in any way affect or
modify, any obligation or liability of the Company or the Subsidiaries with
respect to any of the Collateral or any transaction in connection therewith.

SECTION 4.  DELIVERY OF PLEDGED SECURITIES.

                  All certificates representing Pledged Stock delivered to the
Agent by the Company pursuant hereto shall be in suitable form for transfer by
delivery, or shall be accompanied by duly executed instruments of transfer or
assignment in blank, and accompanied by any required transfer tax stamps, all in
form and substance satisfactory to the Agent.


                                      G-3
<PAGE>   114

SECTION 5.  FILING; FURTHER ASSURANCES.

                  (A) The Company agrees that it will, at its expense and in
such manner and form as the Agent may require, execute, deliver, file and record
any financing statement, specific assignment or other paper and take any other
action that may be necessary or desirable, or that the Agent may request, in
order to create, preserve, perfect or validate any Security Interest or to
enable the Agent to exercise and enforce its rights hereunder with respect to
any of the Collateral. To the extent permitted by applicable law, the Company
hereby authorizes the Agent to execute and file, in the name of the Company or
otherwise, UCC financing statements (which may be carbon, photographic,
photostatic or other reproductions of this Agreement or of a financing statement
relating to this Agreement) which the Agent in its sole discretion may deem
necessary or appropriate to further perfect the Security Interests.

                  (B) The Company agrees that it will not change (i) its name,
identity or form of organization in any manner or (ii) the location of its chief
executive office unless it shall have given the Agent not less than 30 days'
prior notice thereof.

SECTION 6.  RECORD OWNERSHIP OF PLEDGED STOCK.

                  The Agent may at any time or from time to time, upon the
occurrence and during the continuance of an Event of Default, in its sole
discretion, cause any or all of the Pledged Stock to be transferred of record
into the name of the Agent or its nominee. The Company will promptly give to the
Agent copies of any notices or other communications received by it with respect
to Pledged Stock registered in the name of the Company and the Agent will
promptly give to the Company copies of any notices and communications received
by the Agent with respect to Pledged Stock registered in the name of the Agent
or its nominee.

SECTION 7.  RIGHT TO RECEIVE DISTRIBUTIONS ON COLLATERAL.

                  Upon the occurrence and during the continuance of any Event of
Default, the Agent shall have the right to receive and to retain as Collateral
hereunder all dividends, interest and other payments and distributions made upon
or with respect to the Collateral and the Company shall take all such action as
the Agent may deem necessary or appropriate to give effect to such right. Upon
the occurrence and during the continuance of an Event of Default, all such
dividends, interest and other payments and distributions which are received by
the Company shall be received in trust as Collateral for the benefit of the
Agent and the Secured Parties and, if the Agent so directs, shall be segregated
from other funds of the Company and shall, forthwith upon demand by the Agent
during the continuance of an Event of Default, be paid over to the Agent as
Collateral in the same form as received (with any necessary endorsement). After
all Events of Default that shall have occurred have been cured, the Agent's
right to retain dividends, interest and other payments and distributions under
this Section 7 shall cease and the Agent shall pay over to the Company any such
Collateral retained by the Agent during the continuance of an Event of Default.


                                      G-4
<PAGE>   115

SECTION 8.  RIGHT TO VOTE PLEDGED STOCK.

                  Unless an Event of Default shall have occurred and be
continuing, the Company shall have the right, from time to time, to vote and to
give consents, ratifications and waivers with respect to the Pledged Stock, and
the Agent shall, upon receiving a written request from the Company accompanied
by a certificate signed by its principal financial officer stating that no Event
of Default has occurred and is continuing, deliver to the Company or as
specified in such request such proxies, powers of attorney, consents,
ratifications and waivers in respect of any of the Pledged Stock which is
registered in the name of the Agent or its nominee as shall be specified in such
request and be in form and substance satisfactory to the Agent.

                  If an Event of Default shall have occurred and be continuing,
the Agent shall have the right to the extent permitted by law and the Company
shall take all such action as may be necessary or appropriate to give effect to
such right, to vote and to give consents, ratifications and waivers, and take
any other action with respect to any or all of the Pledged Stock with the same
force and effect as if the Agent were the absolute and sole owner thereof.

SECTION 9.  GENERAL AUTHORITY.

                  The Company hereby irrevocably appoints the Agent its true and
lawful attorney, with full power of substitution, in the name of the Company,
the Agent, the Secured Parties or otherwise, for the sole use and benefit of the
Agent and Secured Parties, but at the expense of the Company, to the extent
permitted by law to exercise, at any time and from time to time while an Event
of Default has occurred and is continuing, all or any of the following powers
with respect to all or any of the Collateral:

                  (i)   to demand, sue for, collect, receive and give
         acquittance for any and all monies due or to become due upon or by
         virtue thereof,

                  (ii)  settle, compromise, compound, prosecute or defend any
         action or proceeding with respect thereto,

                  (iii) to sell, transfer, assign or otherwise deal in or with
         the same or the proceeds or avails thereof, as fully and effectually as
         if the Agent were the absolute owner thereof, and

                  (iv)  to extend the time of payment of any or all thereof and
         to make any allowance and other adjustments with reference thereto;

provided that the Agent shall give the Company not less than ten days' prior
written notice of the time and place of any sale or other intended disposition
of any of the Collateral except any Collateral which is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market. The Agent and the Company agree that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC.


                                      G-5
<PAGE>   116

SECTION 10.  REMEDIES UPON EVENT OF DEFAULT.

                  If any Event of Default shall have occurred and be continuing,
the Agent may exercise on behalf of the Secured Parties all the rights of a
secured party under the UCC (whether or not in effect in the jurisdiction where
such rights are exercised) and, in addition, the Agent may, without being
required to give any notice, except as herein provided or as may be required by
mandatory provisions of law, (i) apply the cash, if any, then held by it as
Collateral as specified in Section 13 and (ii) if there shall be no such cash or
if such cash shall be insufficient to pay all the Secured Obligations in full,
sell the Collateral or any part thereof at public or private sale or at any
broker's board or on any securities exchange, for cash, upon credit or for
future delivery, and at such price or prices as the Agent may deem satisfactory.
Any Secured Party may be the purchaser of any or all of the Collateral so sold
at any public sale (or, if the Collateral is of a type customarily sold in a
recognized market or is of a type which is the subject of widely distributed
standard price quotations, at any private sale). The Agent is authorized, in
connection with any such sale, if it deems it advisable so to do, (i) to
restrict the prospective bidders on or purchasers of any of the Pledged
Securities to a limited number of sophisticated investors who will represent and
agree that they are purchasing for their own account for investment and not with
a view to the distribution or sale of any of such Pledged Securities, (ii) to
cause to be placed on certificates for any or all of the Pledged Securities or
on any other securities pledged hereunder a legend to the effect that such
security has not been registered under the Securities Act of 1933 and may not be
disposed of in violation of the provision of said Act, and (iii) to impose such
other limitations or conditions in connection with any such sale as the Agent
deems necessary or advisable in order to comply with said Act or any other law.
The Company covenants and agrees that it will execute and deliver such documents
and take such other action as the Agent deems necessary or advisable in order
that any such sale may be made in compliance with law. Upon any such sale the
Agent shall have the right to deliver, assign and transfer to the purchaser
thereof the Collateral so sold. Each purchaser at any such sale shall hold the
Collateral so sold absolutely and free from any claim or right of whatsoever
kind, including any equity or right of redemption of the Company which may be
waived, and the Company, to the extent permitted by law, hereby specifically
waives all rights of redemption, stay or appraisal which it has or may have
under any law now existing or hereafter adopted. The notice (if any) of such
sale required by Section 9 shall (1) in case of a public sale, state the time
and place fixed for such sale, (2) in case of sale at a broker's board or on a
securities exchange, state the board or exchange at which such sale is to be
made and the day on which the Collateral, or the portion thereof so being sold,
will first be offered for sale at such board or exchange, and (3) in the case of
a private sale, state the day after which such sale may be consummated. Any such
public sale shall be held at such time or times within ordinary business hours
and at such place or places as the Agent may fix in the notice of such sale. At
any such sale the Collateral may be sold in one lot as an entirety or in
separate parcels, as the Agent may determine. The Agent shall not be obligated
to make any such sale pursuant to any such notice. The Agent may, without notice
or publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by the Agent until
the selling price is paid by the purchaser thereof, but the Agent


                                      G-6
<PAGE>   117

shall not incur any liability in case of the failure of such purchaser to take
up and pay for the Collateral so sold and, in case of any such failure, such
Collateral may again be sold upon like notice. The Agent, instead of exercising
the power of sale herein conferred upon it, may proceed by a suit or suits at
law or in equity to foreclose the Security Interests and sell the Collateral, or
any portion thereof, under a judgment or decree of a court or courts of
competent jurisdiction.

SECTION 11.  EXPENSES.

                  The Company agrees that it will forthwith upon demand pay to
the Agent:

                  (i)  the amount of any taxes which the Agent may have been
         required to pay by reason of the Security Interests or to free any of
         the Collateral from any Lien thereon, and

                  (ii) the amount of any and all out-of-pocket expenses,
         including the reasonable fees and disbursements of counsel and of any
         other experts, which the Agent may incur in connection with (w) the
         administration or enforcement of this Agreement, including such
         expenses as are incurred to preserve the value of the Collateral and
         the validity, perfection, rank and value of any Security Interest, (x)
         the collection, sale or other disposition of any of the Collateral, (y)
         the exercise by the Agent of any of the rights conferred upon it
         hereunder or (z) any Default or Event of Default.

Any such amount not paid on demand shall bear interest as provided in Section
10.03 of the Credit Agreement.

SECTION 12.  LIMITATION ON DUTY OF AGENT IN RESPECT OF COLLATERAL.

                  Beyond the exercise of reasonable care in the custody thereof,
the Agent shall have no duty as to any Collateral in its possession or control
or in the possession or control of any agent or bailee or any income thereon or
as to the preservation of rights against prior parties or any other rights
pertaining thereto. The Agent shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which it accords
its own property, and shall not be liable or responsible for any loss or damage
to any of the Collateral, or for any diminution in the value thereof, by reason
of the act or omission of any agent or bailee selected by the Agent in good
faith.

SECTION 13.  APPLICATION OF PROCEEDS.

                  Upon the occurrence and during the continuance of an Event of
Default, the proceeds of any sale of, or other realization upon, all or any part
of the Collateral and any cash held shall be applied by the Agent in the
following order of priorities:

                  first, to payment of the expenses of such sale or other
         realization, including reasonable compensation to agents and counsel
         for the Agent, and all expenses, liabilities 


                                      G-7
<PAGE>   118

         and advances incurred or made by the Agent in connection therewith, and
         any other unreimbursed expenses for which the Agent or any Secured
         Party is to be reimbursed pursuant to Section 10.04 of the Credit
         Agreement or Section 11 hereof and unpaid fees owing to the Agent under
         the Credit Agreement;

                  second, to the ratable payment of accrued but unpaid interest
         on the Secured Obligations in accordance with the provisions of the
         Credit Agreement;

                  third, to the ratable payment of unpaid principal of the

         assigns, or as a court of competent jurisdiction may direct, of any

SECTION 14.  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.

SECTION 15.  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
Secured Parties 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 


                                      G-8

the protection of such co-agent or separate agent similar to the provisions of
Section 14).

SECTION 16.  TERMINATION OF SECURITY INTERESTS; RELEASE OF COLLATERAL.

                  Upon the repayment in full of all Secured Obligations (other
than contingent indemnity or similar claims not yet asserted) and the
termination of the Commitment under the Credit Agreement, the Security Interests
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, the Agent may release any of the Collateral with the prior written
consent of the Lenders. Upon any such termination of the 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.

                  All notices, communications and distributions hereunder shall
be given in accordance with Section 12.03 of the Credit Agreement.

SECTION 18.  WAIVERS, NON-EXCLUSIVE REMEDIES.

                  No failure on the part of the Agent to exercise, and no delay
in exercising and no course of dealing with respect to, any right under this
Agreement shall operate as a waiver thereof; nor shall any single or partial
exercise by the Agent of any right under the Credit Agreement, any other
Financing Document or this Agreement preclude any other or further exercise
thereof or the exercise of any other right. The rights in this Agreement, the
other Security Documents and the Credit Agreement are cumulative and are not
exclusive of any other remedies provided by law.

SECTION 19.  SUCCESSORS AND ASSIGNS.

                  This Agreement is for the benefit of the Agent and the other
Secured Parties and their successors and assigns, and in the event of an
assignment of all or any of the Secured Obligations, the rights hereunder, to
the extent applicable to the indebtedness so assigned, may be transferred with
such indebtedness. This Agreement shall be binding on the Company and its
successors and assigns.

SECTION 20.  CHANGES IN WRITING.

                  Neither this Agreement nor any provision hereof may be
changed, waived, discharged or terminated orally, but only in writing signed by
the Company and the Agent with the consent of the Required Lenders (or in the
case of Section 16, all of the Lenders).

SECTION 2.  REPRESENTATIONS AND WARRANTIES.

                  Each Pledgor represents and warrants as follows:

                  (A) Each Pledgor has good and marketable title to all of the
Collateral, free and clear of any Liens other than the Permitted Liens. Each
Pledgor has taken all actions necessary under the UCC to perfect its interest in
any Accounts purchased or otherwise acquired by or granted to it, as against its
assignors and grantors and creditors of its assignors and grantors.

                  (B) No Pledgor has performed any acts which might prevent the
Agent from enforcing any of the terms of this Agreement or which would limit the
Agent in any such enforcement. Other than financing statements or other similar
or equivalent documents or instruments with respect to the Security Interests
and Permitted Liens, no financing statement, mortgage, security agreement or
similar or equivalent document or instrument covering all or any part of the
Collateral is on file or of record in any jurisdiction in which such filing or
recording would be effective to perfect a Lien on such Collateral. No Collateral
is in the possession of any Person (other than a Pledgor or the Company)
asserting any claim thereto or security interest therein, except that the Agent
or its designee may have possession of Collateral as contemplated hereby.

                  (C) The information set forth in each Perfection Certificate
delivered to the Agent prior to the Closing Date is correct and complete as of
the Closing Date.

                  (D) The Security Interests constitute valid security interests
under the UCC securing the Secured Obligations. When UCC financing statements in
the form specified in Schedule 6 to the Perfection Certificate shall have been
filed in the offices specified in each Perfection Certificate, the Security
Interests shall constitute perfected security interests in the Collateral
(except Inventory in transit) to the extent that a security interest therein may
be perfected by filing pursuant to the UCC, prior to all other Liens and rights
of others therein except for the Permitted Liens.

                  (E) The Inventory and Equipment are insured in accordance with
the requirements of the Credit Agreement.

                  (F) Exhibit B (as updated by such Pledgor from time to time
with the consent of the Agent, such consent not to be unreasonably withheld)
lists each bank account, money market account and investment account for each
Pledgor.


                                      I-4
<PAGE>   127

SECTION 3.  THE SECURITY INTERESTS.

                  (A) In order to secure the full and punctual payment and
performance of the Secured Obligations in accordance with the terms thereof,
each Pledgor hereby grants to the Agent for the ratable benefit of the Secured
Parties a continuing security interest in and to all of the following property
of such Pledgor, whether now owned or existing or hereafter acquired or arising
and regardless of where located (all being collectively referred to as the
"COLLATERAL"):

                  (1)  Accounts;

                  (2)  Inventory;

                  (3)  General Intangibles;

                  (4)  Documents;

                  (5)  Instruments;

                  (6)  Equipment;

                  (7)  The Lockbox Accounts, all cash deposited in any of the
         foregoing from time to time, the Liquid Investments made pursuant to
         Section 5(D) and other monies and property of any kind of such Pledgor
         in the possession or under the control of the Agent;

                  (8)  All books and records (including customer lists, credit
         files, computer programs, printouts and other computer materials and
         records) of such Pledgor pertaining to any of the Collateral;

                  (9)  Insurance policies of such Pledgor; and

                  (10) All Proceeds of all or any of the Collateral described in
         Clauses 1 through 9 hereof.

                  (B) The Security Interests are granted as security only and
shall not subject any Secured Party to, or transfer or in any way affect or
modify, any obligation or liability of any Pledgor with respect to any of the
Collateral or any transaction in connection therewith.

SECTION 4.  FURTHER ASSURANCES; COVENANTS.

                  (A) No Pledgor will change its name, identity or form of
organization in any manner unless it shall have given the Agent prior notice
thereof and delivered an opinion of counsel with respect thereto in accordance
with Section 4(L). No Pledgor will change the location of (i) its chief
executive office or chief place of business or (ii) the locations where it keeps
or holds any Collateral or any records relating thereto from the applicable
location described in the Perfection Certificate of such Pledgor unless it shall
have given the Agent prior 


                                      I-5
<PAGE>   128

notice thereof and delivered an opinion of counsel with respect thereto in
accordance with Section 4(L).

                  (B) No Pledgor shall in any event change the location of any
Collateral without the prior written consent of the Agent if such change would
cause the Security Interests in such Collateral to lapse or cease to be
perfected.

                  (C) Each Pledgor will, from time to time, at its expense,
execute, deliver, file and record any statement, assignment, instrument,
document, agreement or other paper and take any other action (including any
filings of financing or continuation statements under the UCC) that from time to
time may be necessary or desirable, or that the Agent may request, in order to
create, preserve, perfect, confirm or validate the Security Interests or to
enable the Secured Parties to obtain the full benefits of this Agreement, or to
enable the Agent to exercise and enforce any of its rights, powers and remedies
hereunder with respect to any of the Collateral. To the extent permitted by
applicable law, each Pledgor hereby authorizes the Agent, and appoints the Agent
as its true and lawful attorney (with full power of substitution, in the name of
such Pledgor, the Secured Parties or otherwise, for the sole use and benefit of
the Secured Parties), to execute and file financing statements or continuation
statements without such Pledgor's signature appearing thereon. Each Pledgor
agrees that a carbon, photographic, photostatic or other reproduction of this
Agreement or of a financing statement is sufficient as a financing statement.
Each Pledgor shall pay the costs of, or incidental to, any recording or filing
of any financing or continuation statements concerning the Collateral.

                  (D) If any Collateral is at any time in the possession or
control of any warehouseman, bailee or any of any Pledgor's agents or
processors, such Pledgor shall notify such warehouseman, bailee, agent or
processor of the Security Interests created hereby and to hold all such
Collateral for the Agent's account subject to the Agent's instructions.

                  (E) Each Pledgor shall keep full and accurate books and
records relating to the Collateral, and stamp or otherwise mark such books and
records in such manner as the Agent may reasonably require in order to reflect
the Security Interests.

                  (F) Each Pledgor will immediately deliver and pledge each
Instrument to the Agent, appropriately endorsed to the Agent, provided that so
long as no Event of Default shall have occurred and be continuing, such Pledgor
may retain for collection in the ordinary course any Instruments.

                  (G) Each Pledgor shall use its reasonable best efforts to
cause to be collected from its Account Debtors, as and when due, any and all
amounts owing under or on account of each Account (including Accounts which are
delinquent, such Accounts to be collected in accordance with lawful collection
procedures and such Pledgor's customary practices) and shall apply forthwith
upon receipt thereof all such amounts as are so collected to the outstanding
balance of such Account. Subject to the rights of the Secured Parties hereunder
upon the occurrence and during the continuance of an Event of Default, each
Pledgor may allow in the ordinary course of business as adjustments to amounts
owing under its Accounts (i) an extension


                                      I-6
<PAGE>   129

or renewal of the time or times of payment, or settlement for less than the
total unpaid balance, which such Pledgor finds appropriate in accordance with
sound business judgment unless such extension, renewal or settlement results in
causing such Account to not be an Eligible Receivable and thereby causes the
aggregate unpaid balance of Working Capital Loans to exceed the Borrowing Base
and (ii) a refund or credit due as a result of returned or damaged merchandise
or as a discount for prompt payment, all in accordance with such Pledgor's
ordinary course of business consistent with its historical collection practices.
The costs and expenses (including attorney's fees) of collection, whether
incurred by any Pledgor or the Agent, shall be borne by such Pledgor.

                  (H) Upon the occurrence and during the continuance of any
Event of Default, upon request of the Required Lenders through the Agent, to the
extent permitted by applicable law each Pledgor will promptly notify (and hereby
authorizes the Agent so to notify) each Account Debtor in respect of any Account
or Instrument that such Collateral has been assigned to the Agent hereunder, and
that any payments due or to become due in respect of such Collateral are to be
made directly to the Agent or its designee.

                  (I) Each Pledgor shall not permit any items of Equipment to
become a fixture to real estate (unless the Agent has a first priority Lien
thereon) or an accession to other personal property.

                  (J) Without the prior written consent of the Agent and except
in the ordinary course of any Pledgor's business, no Pledgor will sell, lease,
exchange, assign or otherwise dispose of, or grant any option with respect to,
any Collateral except, subject to the rights of the Secured Parties hereunder if
an Event of Default shall have occurred and be continuing, as permitted under
the Credit Agreement including Section 6.06, whereupon, in the case of such a
sale or exchange, the Security Interests created hereby in such item (but not in
any Proceeds arising from such sale or exchange) shall cease immediately without
any further action on the part of the Agent.

                  (K) Each Pledgor will, promptly upon request, provide to the
Agent all information and evidence it may reasonably request concerning the
Collateral to enable the Agent to enforce the provisions of this Agreement.

                  (L) Not more than six months nor less than 30 days prior to
each date on which any Pledgor proposes to take any action contemplated by
Section 4(A), such Pledgor shall give notice to the Agent of such proposed
action, and, at such Pledgor's cost and expense, cause to be delivered to the
Secured Parties with such notice, an opinion of counsel, satisfactory to the
Agent and substantially in the form of Exhibit D to the effect that all
financing statements and amendments or supplements thereto, continuation
statements and other documents required to be recorded or filed in order to
perfect and protect the Security Interests have been filed in each filing office
necessary for such purpose and that all filing fees and taxes, if any, payable
in connection with such filings have been paid in full.

                  (M) No Pledgor shall open or maintain any bank account, money
market account or investment account unless such account shall first be listed
on Exhibit B (as updated by such Pledgor from time to time with the consent of
the Agent, such consent not to be unreasonably withheld) and, if the Agent
requires in its sole discretion, shall be subject to a Lockbox Agreement.

                  (N) Each Pledgor shall (i) upon the occurrence of an Event of
Default and (ii) within 10 days after the aggregate value of all Equipment
consisting of motor vehicles, trucks and trailers owned by the Company and its
Subsidiaries shall exceed $150,000, deliver to the Agent any and all
certificates of title, applications for title or similar evidence of ownership
of such Equipment and shall cause the Agent to be named as lienholder on any
such certificate of title or other evidence of ownership.

SECTION 5.  LOCKBOX ACCOUNT.

                  (A) On the Closing Date, each Pledgor shall deliver to the
Agent for each account listed for such Pledgor on Exhibit B hereto (each a
"LOCKBOX ACCOUNT"), a lockbox agreement substantially in form of Exhibit E
hereto or in such other form as shall be satisfactory to the Agent (each a
"LOCKBOX AGREEMENT") which shall establish such account in the name
"NationsCredit Commercial Corporation, as Agent", and under the exclusive
control of the Agent. From and after the Closing Date, there shall be deposited
from time to time into the Lockbox Accounts the cash Proceeds of the Collateral
required to be delivered to the Agent pursuant to subsection (B) of this Section
5 or any other provision of this Agreement and all other funds of such Pledgor.
Any income received with respect to the balance from time to time standing to
the credit of each Lockbox Account, including any interest or capital gains on
Liquid Investments, may be withdrawn by the Company from such Lockbox Account in
accordance with subsection (C) below. All right, title and interest in and to
the cash amounts on deposit from time to time in the Lockbox Accounts together
with any Liquid Investments from time to time made pursuant to subsection (D) of
this Section shall vest in the Agent (pursuant to the Lockbox Agreement for each
Lockbox Account), shall constitute part of the Collateral hereunder and shall
not constitute payment of the Secured Obligations until applied thereto as
hereinafter provided.

                  (B) Each Pledgor shall instruct all Account Debtors and other
Persons obligated in respect of all Accounts, to make all payments in respect of
such Accounts and shall use its reasonable best efforts to cause such Account
Debtors and other Persons to remit all such payments directly to a Lockbox
Account of such Pledgor (if paid by wire transfer). In addition to the
foregoing, each Pledgor agrees that if the proceeds of any Collateral hereunder
(including the payments made in respect of Accounts) shall be received by such
Pledgor, such Pledgor shall as promptly as possible deposit such proceeds into
its Lockbox Account. Until so deposited, all such proceeds shall be held in
trust by such Pledgor for and as the property of the Secured Parties and shall
not be commingled with any other funds or property of such Pledgor.

                  (C) The balance from time to time standing to the credit of
the Lockbox Accounts shall, except upon the occurrence and continuation of an
Event of Default, be 


                                      I-8
<PAGE>   131

distributed to each Pledgor in accordance with the provisions of each Lockbox
Agreement. If immediately available cash on deposit in the Lockbox Accounts is
not sufficient to make any distribution to any Pledgor referred to in the
previous sentence of this Section 5(C), the Agent shall cause to be liquidated
as promptly as practicable Liquid Investments in the Lockbox Accounts designated
by the Pledgors as required to obtain sufficient cash to make such distribution
and, notwithstanding any other provision of this Section 5, such distribution
shall not be made until such liquidation has taken place. Upon the occurrence
and continuation of an Event of Default, the Agent shall, if so instructed by
the Required Lenders, apply or cause to be applied (subject to collection) any
or all of the balance from time to time standing to the credit of any Lockbox
Accounts in the manner specified in Section 9.

                  (D) Amounts on deposit in the Lockbox Accounts shall be
invested and re-invested from time to time in such Liquid Investments as the
Pledgors shall determine, which Liquid Investments shall be held in the name and
be under the control of the Agent; provided that, if an Event of Default has
occurred and is continuing, the Agent shall, if instructed by the Required
Lenders, cause such Liquid Investments to be liquidated and apply or cause to be
applied the proceeds thereof to the payment of the Secured Obligations in the
manner specified in Section 9. For this purpose, "Liquid Investments" means
Temporary Cash Investments; provided that (i) each Liquid Investment shall
mature within 30 days after it is acquired by the Agent and (ii) in order to
provide the Agent, for the benefit of the Secured Parties, with a perfected
security interest therein, each Liquid Investment shall be either:

                  (i)  evidenced by negotiable certificates or instruments, or
         if non-negotiable then issued in the name of the Agent, which (together
         with any appropriate instruments of transfer) are delivered to, and
         held by, the Agent or an agent thereof (which shall not be the Company
         or any of its Affiliates) in the State of Georgia; or

                  (ii) in book-entry form and issued by the United States and
         subject to pledge under applicable state law and Treasury regulations
         and as to which (in the opinion of counsel to the Agent) appropriate
         measures shall have been taken for perfection of the Security
         Interests.

SECTION 6.  GENERAL AUTHORITY.

                  Each Pledgor hereby irrevocably appoints the Agent its true
and lawful attorney, with full power of substitution, in the name of such
Pledgor, the Secured Parties or otherwise, for the sole use and benefit of the
Secured Parties, but at such Pledgor's expense, to the extent permitted by law
to exercise, at any time and from time to time while an Event of Default has
occurred and is continuing, all or any of the following powers with respect to
all or any of the Collateral:

                  (i)  to demand, sue for, collect, receive and give acquittance
         for any and all monies due or to become due thereon or by virtue
         thereof,


                                      I-9
<PAGE>   132

                  (ii)  to settle, compromise, compound, prosecute or defend any
         action or proceeding with respect thereto,

                  (iii) to sell, transfer, assign or otherwise deal in or with
         the same or the proceeds or avails thereof, as fully and effectually as
         if the Agent were the absolute owner thereof, and

                  (iv)  to extend the time of payment of any or all thereof and
         to make any allowance and other adjustments with reference thereto;

provided that the Agent shall give such Pledgor not less than ten days' prior
written notice of the time and place of any sale or other intended disposition
of any of the Collateral, except any Collateral which is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market. Each Pledgor agrees that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC.

SECTION 7.  REMEDIES UPON EVENT OF DEFAULT.

                  (A) If any Event of Default has occurred and is continuing,
the Agent may exercise on behalf of the Secured Parties all rights of a secured
party under the UCC (whether or not in effect in the jurisdiction where such
rights are exercised) and, in addition, the Agent may, without being required to
give any notice, except as herein or in the Credit Agreement or any other
Financing Document provided or as may be required by mandatory provisions of
law, (i) withdraw all cash and Liquid Investments in the Collateral Accounts and
apply such cash and Liquid Investments and other cash, if any, then held by it
as Collateral as specified in Section 9 and (ii) if there shall be no such cash
or Liquid Investments or if such cash and Liquid Investments shall be
insufficient to pay all the Secured Obligations in full, sell the Collateral or
any part thereof at public or private sale, for cash, upon credit or for future
delivery, and at such price or prices as the Agent may deem satisfactory. The
Agent or any other Secured Party may be the purchaser of any or all of the
Collateral so sold at any public sale (or, if the Collateral is of a type
customarily sold in a recognized market or is of a type which is the subject of
widely distributed standard price quotations, at any private sale). Each Pledgor
will execute and deliver such documents and take such other action as the Agent
deems necessary or advisable in order that any such sale may be made in
compliance with law. Upon any such sale the Agent shall have the right to
deliver, assign and transfer to the purchaser thereof the Collateral so sold.
Each purchaser at any such sale shall hold the Collateral so sold to it
absolutely and free from any claim or right of whatsoever kind, including any
equity or right of redemption of any Pledgor which may be waived, and each
Pledgor, to the extent permitted by law, hereby specifically waives all rights
of redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted. The notice (if any) of such sale required by
Section 6 shall (1) in case of a public sale, state the time and place fixed for
such sale, and (2) in the case of a private sale, state the day after which such
sale may be consummated. Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the Agent
may fix in the notice of such sale. At any such sale the Collateral may be sold
in one lot as an entirety or in separate parcels, as the Agent may determine.
The Agent shall not be obligated to 


                                      I-10
<PAGE>   133

make any such sale pursuant to any such notice. The Agent may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by the Agent until
the selling price is paid by the purchaser thereof, but the Agent shall not
incur any liability in case of the failure of such purchaser to take up and pay
for the Collateral so sold and, in case of any such failure, such Collateral may
again be sold upon like notice. The Agent, instead of exercising the power of
sale herein conferred upon it, may proceed by a suit or suits at law or in
equity to foreclose the Security Interests and sell the Collateral, or any
portion thereof, under a judgment or decree of a court or courts of competent
jurisdiction.

                  (B) For the purpose of enforcing any and all rights and
remedies under this Agreement the Agent may (i) require each Pledgor to, and
each Pledgor agrees that it will, at its expense and upon the request of the
Agent, forthwith assemble all or any part of the Collateral as directed by the
Agent and make it available at a place designated by the Agent which is, in its
opinion, reasonably convenient to the Agent and such Pledgor, whether at the
premises of such Pledgor or otherwise, (ii) to the extent permitted by
applicable law, enter, with or without process of law and without breach of the
peace, any premise where any of the Collateral is or may be located, and without
charge or liability to it seize and remove such Collateral from such premises,
(iii) have access to and use any Pledgor's books and records relating to the
Collateral and (iv) prior to the disposition of the Collateral, store or
transfer it without charge in or by means of any storage or transportation
facility owned or leased by any Pledgor, process, repair or recondition it or
otherwise prepare it for disposition in any manner and to the extent the Agent
deems appropriate and, in connection with such preparation and disposition, use
without charge any trademark, trade name, copyright, patent or technical process
used by any Pledgor.

SECTION 8.  LIMITATION ON DUTY OF AGENT IN RESPECT OF COLLATERAL.

                  Beyond the exercise of reasonable care in the custody thereof,
the Agent shall have no duty as to any Collateral in its possession or control
or in the possession or control of any agent or bailee or any income thereon or
as to the preservation of rights against prior parties or any other rights
pertaining thereto. The Agent shall be deemed to have exercised reasonable care
in the custody of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which it accords its own property, and
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any warehouseman, carrier, forwarding agency, consignee or other
agent or bailee selected by the Agent in good faith.

SECTION 9.  APPLICATION OF PROCEEDS.

                  Upon the occurrence and during the continuance of an Event of
Default, the proceeds of any sale of, or other realization upon, all or any part
of the Collateral and any cash held in the Collateral Accounts shall be applied
by the Agent in the following order of priorities:


                                      I-11
<PAGE>   134

                  first, to payment of the expenses of such sale or other
         realization, including reasonable compensation to agents and counsel
         for the Agent, and all expenses, liabilities and advances incurred or
         made by the Agent in connection therewith, and any other unreimbursed
         expenses for which the Agent or any other Secured Party is to be
         reimbursed pursuant to Section 8.04 of the Credit Agreement or Section
         12 hereof and unpaid fees owing to the Agent under the Credit
         Agreement;

                  second, to the ratable payment of accrued but unpaid interest
         on the Secured Obligations in accordance with the provisions of the
         Credit Agreement;

                  third, to the ratable payment of unpaid principal of the
         Secured Obligations;

                  fourth, to the ratable payment of all other Secured
         Obligations, until all Secured Obligations shall have been paid in
         full; and

                  finally, to payment to the Pledgors or their successors or
         assigns, or as a court of competent jurisdiction may direct, of any
         surplus then remaining from such proceeds.

The Agent may make distributions hereunder in cash or in kind or, on a ratable
basis, in any combination thereof.

SECTION 10.  CONCERNING THE AGENT.

                  The provisions of Section 10.05 and Article XI 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 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
Pledgor.


                                      I-12
<PAGE>   135

SECTION 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
Secured Parties 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).

SECTION 12.  EXPENSES.

                  In the event that any Credit Party shall fail to comply with
the provisions of the Credit Agreement or this Agreement, such that the value of
any Collateral or the validity, perfection, rank or value of any Security
Interest is thereby diminished or potentially diminished or put at risk, the
Agent if requested by the Required Lenders may, but shall not be required to,
effect such compliance on behalf of the Credit Parties, and the Pledgors shall
reimburse the Agent for the costs thereof on demand. All insurance expenses and
all expenses of protecting, storing, warehousing, appraising, insuring,
handling, maintaining, and shipping the Collateral, any and all excise,
property, sales, and use taxes imposed by any state, federal, or local authority
on any of the Collateral, or in respect of periodic appraisals and inspections
of the Collateral to the extent the same may be requested by the Required
Lenders from time to time as provided in the Credit Agreement, or in respect of
the sale or other disposition thereof shall be borne and paid by the Pledgors;
and if any Pledgor fails to promptly pay any portion thereof when due, the Agent
or any other Secured Party may, at its option, but shall not be required to, pay
the same, and such Pledgor agrees to reimburse the Agent or such other Secured
Party therefor on demand. All sums so paid or incurred by the Agent or any other
Secured Party for any of the foregoing and any and all other sums for which the
Pledgors may become liable hereunder and all costs and expenses (including
reasonable attorney's fees, legal expenses and court costs) reasonably incurred
by the Agent or any other Secured Party in enforcing or protecting the Security
Interests or any of their rights or remedies under this Agreement, shall,
together with interest thereon until paid as provided in Section 10.03 of the
Credit Agreement, be additional Secured Obligations hereunder.

SECTION 13.  TERMINATION OF SECURITY INTERESTS; RELEASE OF COLLATERAL.

                  Upon the repayment in full of all Secured Obligations (other
than contingent indemnity or similar claims not yet asserted) and the
termination of the Commitment under the Credit Agreement, the Security Interests
shall terminate and all rights to the Collateral shall revert to the Pledgors.
At any time and from time to time prior to such termination of the Security
Interests, the Agent may release any of the Collateral with the prior written
consent of the Required Lenders. Upon any such termination of the Security
Interests or release of Collateral, the Agent will, at the expense of the
Pledgors, execute and deliver to the Pledgors such documents as the Pledgors
shall reasonably request to evidence the termination of the Security Interests
or the release of such Collateral, as the case may be.


                                      I-13
<PAGE>   136

SECTION 14.  OBLIGATIONS UNCONDITIONAL; DISCHARGE OF OBLIGATIONS, ETC.

                  (a) The Security Interests and the obligations of each Pledgor
hereunder shall not be released, discharged or otherwise affected by:

                  (i)   any extension, renewal, settlement, compromise, waiver
         or release in respect of any obligation of the Company or any other
         Person under any Financing Document, by operation of law or otherwise;

                  (ii)  any modification or amendment of or supplement to any
         Financing Document;

                  (iii) any release, non-perfection or invalidity of any direct
         or indirect security for any obligation of the Company or any other
         Person under any Financing Document;

                  (iv)  any change in the corporate existence, structure or
         ownership of the Company or any insolvency, bankruptcy, reorganization
         or other similar proceeding affecting the Company or any other Person
         or any of their respective assets or any resulting release or discharge
         of any obligation of the Company or any other Person contained in any
         Financing Document;

                  (v)   the existence of any claim, set-off or other rights
         which such Pledgor may have at any time against the Agent, any Lender
         or any other Person, whether in connection herewith or any unrelated
         transactions, provided that nothing herein shall prevent the assertion
         of any such claim by separate suit or compulsory counterclaim;

                  (vi)  any invalidity or unenforceability relating to or
         against the Company or any other Person for any reason of any Financing
         Document, or any provision of applicable law or regulation purporting
         to prohibit the payment by the Company of the principal of or interest
         on any Note or any other amount payable by the Company or any other
         Person under any Financing Document; or

                  (vii) any other act or omission to act or delay of any kind by
         the Agent, any Lender or any other Person or any other circumstance
         whatsoever which might, but for the provisions of this paragraph,
         constitute a legal or equitable discharge of the obligations of a
         surety.

                  (b) Each Pledgor irrevocably waives acceptance hereof,
presentment, demand, protest and any notice not provided for herein, as well as
any requirement that at any time any action be taken by any corporation or
Person against the Company or any other corporation or Person.


                                      I-14
<PAGE>   137

                  (c) Each Pledgor hereby waives any right or claim of
exoneration, reimbursement, subrogation, contribution or indemnity and any other
similar right or claim arising out of this Agreement.

                  (d) If acceleration of the time for payment of any amount
payable by the Company under the Credit Agreement or any Note is stayed upon the
insolvency, bankruptcy or reorganization of the Company, the Security Interests
and the obligations of each Pledgor hereunder may nonetheless be enforced as
fully as if such acceleration were effective.

SECTION 15.   NOTICES.

                  All notices, communications and distributions hereunder to the
Agent shall be given in accordance with Section 12.03 of the Credit Agreement.
All notices, communications and distributions hereunder to any Pledgor shall be
given in accordance with Section 12.03 of the Credit Agreement and sent to the
address of the Borrower set forth on the signature page of the Credit Agreement.

SECTION 16.  WAIVERS, NON-EXCLUSIVE REMEDIES.

                  No failure on the part of the Agent to exercise, and no delay
in exercising and no course of dealing with respect to, any right under this
Agreement shall operate as a waiver thereof; nor shall any single or partial
exercise by the Agent or any Secured Party of any right under the Credit
Agreement, any of the other Financing Documents or this Agreement preclude any
other or further exercise thereof or the exercise of any other right. The rights
in this Agreement, the Credit Agreement and the other Financing Documents are
cumulative and are not exclusive of any other remedies provided by law.

SECTION 17.  SUCCESSORS AND ASSIGNS.

                  This Agreement is for the benefit of the Agent and the Secured
Parties and their successors and assigns, and in the event of an assignment of
all or any of the Secured Obligations, the rights hereunder, to the extent
applicable to the indebtedness so assigned, may be transferred with such
indebtedness. This Agreement shall be binding on the Pledgor and their
respective successors and assigns.

SECTION 18.  CHANGES IN WRITING.

                  Neither this Agreement nor any provision hereof may be
changed, waived, discharged or terminated orally, but only in writing signed by
the Pledgors and the Agent with the consent of the Required Lenders.

SECTION 19.  GEORGIA LAW.

                  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF GEORGIA (WITHOUT


                                      I-15
<PAGE>   138

REFERENCE TO PRINCIPLES OR CONFLICTS OF LAW), EXCEPT AS OTHERWISE REQUIRED BY
MANDATORY PROVISIONS OF LAW AND EXCEPT TO THE EXTENT THAT REMEDIES PROVIDED BY
THE LAWS OF ANY JURISDICTION OTHER THAN GEORGIA ARE GOVERNED BY THE LAWS OF SUCH
JURISDICTION.

SECTION 20.  SEVERABILITY.

                  If any provision hereof is invalid or unenforceable in any
jurisdiction, then, to the fullest extent permitted by law, (i) the other
provisions hereof shall remain in full force and effect in such jurisdiction and
shall be liberally construed in favor of the Agent and the other Secured Parties
in order to carry out the intentions of the parties hereto as nearly as may be
possible; and (ii) the invalidity or unenforceability of any provision hereof in
any jurisdiction shall not affect the validity or enforceability of such
provision in any other jurisdiction.

SECTION 21.  COUNTERPARTS.

                  This Agreement may be signed in any number of counterparts,
each of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument.

                                   OPINION OF
                             COUNSEL FOR THE PLEDGOR

                                     * * * *

                  1. The Security Agreement creates a valid security interest,
for the benefit of the Secured Parties, in all the Pledgor's right, title and
interest in all Collateral to the extent the UCC is applicable thereto (the
"Security Interest").

                  2. UCC financing statements and amendments thereto
(collectively, the "Financing Statements") have been filed in the filing offices
listed in Schedule 7 to the Perfection Certificate (the "Filing Jurisdictions"),
which are all of the offices in which filings are required to perfect the
Security Interest, to the extent the Security Interest may be perfected by
filing under the UCC, and no further filing or recording of any document or
instrument or other action will be required so to perfect the Security Interest
in the Collateral in which a security interest may be perfected by filing a
financing statement under the UCC, except that (i) continuation statements with
respect to each Financing Statement must be filed in accordance with the UCC;
(ii) additional filings may be necessary if the Pledgor changes its name,
identity or corporate structure or the jurisdiction in which its places of
business, its chief executive office or the Collateral are located; and (iii) we
express no opinion on the perfection of, or need for further filing or recording
to perfect, the Security Interest in goods now or hereafter located in any
jurisdiction other than the Filing Jurisdictions.

                  3. There are

                  (i)  based on [describe search reports], as of the date of
         such reports, no UCC financing statements which name the Pledgor as
         Pledgor or seller and cover any of the Collateral, other than the
         Financing Statements, [and the financing statements with respect to
         Permitted Liens annexed as Schedule 5(A) to the Perfection
         Certificate], listed in the available records in the UCC filing offices
         set forth in paragraphs 2 and 3 of the Perfection Certificate, which,
         based on the information provided to us as to the location of the
         Collateral, the Company and its banks and records, include all of the
         offices prescribed under the UCC as the offices in which filings should
         have been made to perfect security interests in the Collateral; and

                  (ii) based on [describe search reports], as of the date of
         such reports, no notices of the filing of any federal tax lien (filed
         pursuant to Section 6323 of the Internal Revenue Code) or any lien of
         the Pension Benefit Guaranty Corporation (filed pursuant to Section
         4068 of ERISA) covering any of the Collateral listed in the available
         records in the [UCC filing office in state of Pledgor's chief executive
         office], which is the only office having files which must be searched
         in order to fully determine the existence of notices of the filing of
         federal tax liens (filed pursuant to Section 6323 of the Internal

<PAGE>   148

         Revenue Code) on the Collateral and liens of the Pension Benefit
         Guaranty Corporation (filed pursuant to Section 4068 of ERISA) on the
         Collateral.

                  4. The Security Interest validly secures the guaranty by the
Pledgor of the payment of all future Loans made by the Lenders to the Company,
whether or not at the time such Loans are made an Event of Default or other
event not within the control of the Lenders has relieved or may relieve the
Lenders from their obligations to make such Loans, and is perfected to the
extent set forth in paragraph 2 above with respect to such future Loans. Insofar
as the priority thereof is governed by the UCC, the Security Interest has the
same priority with respect to such future Loans as it does with respect to Loans
made on the date hereof.

                  Such opinion may contain such assumptions, qualifications and
limitations as the opinions of counsel for the Company delivered in connection
with the making of the initial Loan under the Credit Agreement.
