         WHEREAS, the Company acknowledges and agrees that the security interest

                                    ARTICLE 1

                                    THE LOANS

         Section 1.1       Extension of Credit.

                (a) Revolving Loans. Subject to the terms and conditions of, and
in reliance upon the representations and warranties made in, this Agreement and
the other Loan Documents, the Lender agrees to lend and relend to the Company,
prior to the Maturity Date, amounts which in the aggregate at any one time
outstanding do not exceed the lesser of (i) the Advance Rate and (ii) the
Commitment. Subject to the terms and conditions hereof and prior to the Maturity
Date, Advances under the Commitment may be repaid and reborrowed from time to
time on a revolving basis.

                (b) Overadvances. If at any time, the Revolving Loans exceed the
Advance Rate, the Commitment or any other applicable limitation set forth in
this Agreement, such Revolving Loans shall nevertheless constitute Obligations
that are secured by the Collateral and are entitled to all benefits thereof. In
no event, however, shall the Company have the right whatsoever to receive any
Revolving Loan if, before or after giving effect thereto, there shall exist a
Default or an overadvance. In the event that the Lender, in its sole and
absolute discretion, shall make any Revolving Loan which in such case gives rise
to an overadvance, the Revolving Loans in an aggregate principal amount equal to
such overadvance shall be payable on demand.




                                        2

                (c) Extension of Maturity Date. The Company may request the
Lender to extend the Maturity Date for an additional one year period by giving
notice of such request to the Lender in writing, not less than sixty (60) days
prior to the Maturity Date. The Lender shall respond to the Company as to its
approval or refusal to agree to so extend the Maturity Date not later than
thirty (30) days prior to the Maturity Date. The Lender is entitled to exercise
its sole, absolute and unconditional discretion in deciding whether or not to
agree to extend the Maturity Date.

         Section 1.2       Revolving Loan Borrowing Mechanics and Disbursement.

                (a) Choice of Interest Rate, etc. Any Advance under the
Commitment shall, at the option of the Company, be made as a Base Rate Advance
or a LIBOR Advance; provided, however, that (i) at such time as there shall have
occurred and be continuing a Default or an Event of Default hereunder, the
Company shall not have the right to reborrow any LIBOR Advance, and all
subsequent Advances during the period such Default or Event of Default continues
shall be made as Base Rate Advances and (ii) if the Company fails to give the
Lender written notice specifying whether an Advance is to be repaid or
reborrowed on a Payment Date, such Advance shall be deemed to be repaid and then
reborrowed as a Base Rate Advance on the Payment Date. Any notice given to the
Lender in connection with a requested Advance hereunder shall be given to the
Lender prior to 11:00 a.m. (Atlanta, Georgia time) in order for such Business
Day to count toward the minimum number of Business Days required. The Lender
shall, upon the reasonable request of the Company from time to time, provide to
the Company such information with regard to the LIBOR Basis as may be so
requested.

                (b) Base Rate Advances.

                     (i)         Initial and Subsequent Advances.  The Company
shall give the Lender in the case of Base Rate Advances not later than 11:00
a.m. (Atlanta, Georgia time) on the Business Day of the date of a proposed
Advance, irrevocable prior notice by telephone or telecopy and shall confirm any
notice by telephone or telecopy with a written Request for Advance or, as
applicable, a written Request for Acquisition Advance.

                     (ii)        Repayments and Reborrowings.  The Company may
repay or prepay a Base Rate Advance and (a) at any time reborrow all or a
portion of the principal amount thereof as one or more Base Rate Advances, (b)
upon at least two (2) Business Days' irrevocable prior written notice to the
Lender, reborrow all or a portion of the principal thereof as one or more LIBOR
Advances, or (c) not reborrow all or any portion of such Base Rate Advance. Upon
the date indicated by the Company, such Base Rate Advance shall be so repaid
and, as applicable, reborrowed.

                     (iii)       Miscellaneous.  Notwithstanding any term or

                (c) LIBOR Advances.

                     (i)         Initial and Subsequent Advances.  The Company
shall give the Lender in the case of LIBOR Advances at least two (2) Business
Days' irrevocable prior notice by telephone or telecopy and shall immediately
confirm any such notice with a written Request for Advance or, as applicable, a
written Request for Acquisition Advance.

                     (ii)        Repayments and Reborrowings.  At least two (2)
days prior to each Payment Date for a LIBOR Advance, the Company shall give the
Lender written notice specifying whether all or a portion of any LIBOR Advance
outstanding on the Payment Date (a) is to be repaid and then reborrowed in whole
or in part as a new LIBOR Advance, in which case such notice shall also specify
the LIBOR Advance Period which the Company shall have selected for such new
LIBOR Advance, (b) is to be repaid and then reborrowed in whole or in part as a
Base Rate Advance or (c) is to be repaid and not reborrowed. Upon such Payment
Date, such LIBOR Advance will, subject to the provisions hereof, be so repaid
and, as applicable, reborrowed.

                     (iii)       Miscellaneous.  Notwithstanding any term or
provision of this Agreement which may be construed to the contrary, (a) each
LIBOR Advance shall be in a principal amount of not less than $500,000 and in an
integral multiple of $100,000 and (b) at no time shall the aggregate number of
all LIBOR Advances then outstanding exceed five (5).

                (d) Telephonic Notice. The failure by the Company to confirm any
notice by telephone or telecopy with a Request for Advance, or a Request for
Acquisition Advance, as applicable, shall not invalidate any notice so given.
The Lender may rely upon telephonic instructions reasonably believed given by
any Authorized Signatory of the Company and shall have no obligation to inquire
into the propriety of any such instructions.

                (e) Disbursement. Prior to 3:00 p.m. (Atlanta, Georgia time) on
the date of an Advance hereunder, the Lender shall, subject to the satisfaction
of the conditions set forth in Section 2.2 hereof disburse the Advance by
depositing such amount in same day funds into the Company's account maintained
with the Lender or by wire transfer pursuant to the Company's instructions.

         Section 1.3       Interest.  Interest on Advances under the Revolving
Loans shall be payable as follows:

                (a) On Base Rate Advances. Interest on Base Rate Advances shall
be computed for the actual number of days elapsed on the basis of a hypothetical
year of 360 days and shall be payable in arrears on the first day of each
calendar month, commencing on August 1, 1998. Interest on Base Rate Advances
outstanding on the Maturity Date shall also be due and payable on the Maturity
Date. Interest shall accrue and be payable on each Base Rate Advance at the
simple per annum interest rate equal to the sum of (A) the Base Rate, plus (B)
the Applicable Interest Rate Margin in effect from time to time and as more
fully set forth in Section 1.3(c) below.

                (b) On LIBOR Advances. Interest on each LIBOR Advance shall be
computed on the basis of a hypothetical year of 360 days for the actual number
of days elapsed and shall be payable in arrears on (x) the Payment Date for such
Advance, and (y) if the LIBOR Advance Period for such Advance is greater than
three (3) months, each three month anniversary of such Advance. Interest on
LIBOR Advances outstanding on the Maturity Date shall also be due and payable on
the Maturity Date. Interest shall accrue and be payable on each LIBOR Advance at
the per annum interest rate equal to (A) the LIBOR Basis applicable to such
LIBOR Advance, plus (B) the Applicable Interest Rate Margin in effect from time
to time and as more fully set forth in Section 1.3(c) below.

                (c) Applicable Interest Rate Margin. The Applicable Interest
Rate Margin for Base Rate Advances shall be zero (0) percent per annum. The
Applicable Interest Rate Margin for LIBOR Advances shall be the interest rate
margin determined by the Lender based upon the Company's Total Funded Debt to
EBITDA ratio for the four quarter period ending on the last day of the most
recent fiscal quarter end, effective as of the second Business Day after the
financial statements referred to in Section 5.1 hereof, and an accompanying
certificate of an Authorized Signatory certifying the calculations of such ratio
as set forth in Section 5.3 hereof, are delivered by the Company to the Lender
for the fiscal quarter most recently ended, expressed as a per annum rate of
interest as follows:

interest on the outstanding Obligations shall accrue at the Default Rate from

be payable on demand and in any event on the Maturity Date and shall accrue
until the earliest to occur of (i) waiver in writing by the Lender of the
applicable Event of Default, (ii) agreement by the Lender to rescind the
charging of interest at the Default Rate or (iii) payment in full of the
Obligations. The Lender shall not be required to (i) accelerate the maturity of
the Revolving Loans or (ii) exercise any other rights or remedies under the Loan
Documents in order to charge interest hereunder at the Default Rate.

                (e) Computation of Interest. In computing interest on any
Advance, the date of making the Advance shall be included and the date of
payment shall be excluded; provided, however, that if an Advance is repaid on
the date that it is made, one (1) day's interest shall be due with respect to
such Advance.

         Section 1.4       Fees.

                (a) Loan Fee. The Company shall cause to be paid to the Lender
on or before the Agreement Date a fee with respect to the Revolving Loans in
amount equal to $30,000. Such fee shall be fully earned when due and
non-refundable when paid.

                (b) Commitment Fee. The Company shall pay an unused line fee to
the Lender for the period beginning on the Agreement Date to and including the
Maturity Date at a rate equal to two fifths of one percent (2/5%) per annum on
the amount by which the Commitment exceeds the aggregate outstanding principal
amount of the Revolving Loans. Such fees shall accrue daily but shall be payable
monthly in arrears on the last Business Day of each month and on the Maturity
Date. Such fee shall be fully earned when due and non-refundable when paid.

         Section 1.5       Repayment and Prepayment.

                (a) Prepayment. The principal amount of any Base Rate Advance
may be prepaid in full or in part at any time, upon written notice to the Lender
on the date of such prepayment, without penalty. LIBOR Advances may be prepaid
prior to the applicable Payment Date, upon at least three (3) Business Days'
prior written notice to the Lender, provided that the Company shall reimburse
the Lender, on the earlier of demand or the Maturity Date, for any loss
(excluding loss of anticipated profit other than loss resulting from any
interest rate differential) or out-of-pocket expense incurred by the Lender in
connection with such prepayment, as set forth in Section 1.8 hereof. Each notice
of prepayment shall be irrevocable, and all amounts prepaid on the Revolving
Loans shall be applied first to interest and fees and other amounts due and
payable hereunder as of such date, and then to principal.

                (b) Repayment. The principal balance of all Revolving Loans then
outstanding shall be due and payable in full on the Maturity Date.
Notwithstanding the foregoing, however, in the event that at any time and for
any reason there shall exist an overadvance, the Company shall immediately pay
to the Lender an amount equal to such overadvance pursuant to Section 1.1(b)
hereof, which payment shall constitute a mandatory payment of the Revolving
Loans hereunder.




         Section 1.6       Notes and Loan Accounts.

                (a) The Revolving Loans shall be payable in accordance with the
terms and provisions of this Agreement and shall be evidenced by the Revolving
Note. The Revolving Note shall be issued by the Company to the Lender and shall
be duly executed and delivered by the Authorized Signatories.

                (b) The Lender shall open and maintain on its books in the name
of the Company a loan account with respect to the Revolving Loans and interest
thereon. The Lender shall debit such loan account for the principal amount of
each Advance and accrued interest thereon, and shall credit such loan account
for each payment on account of principal of or interest on the Revolving Loans.
The records of the Lender with respect to the loan account shall be prima facie
evidence of the Revolving Loans and accrued interest thereon but the failure to
maintain such records shall not impair the obligation of the Company to repay
Indebtedness hereunder.

         Section 1.7       Manner of Payment.

                (a) Each payment (including any prepayment) by the Company on
account of the principal of or interest on the Revolving Loans and any other
amount owed to the Lender under this Agreement or the Revolving Note shall be
made not later than 1:00 p.m. (Atlanta, Georgia time) on the date specified for
payment under this Agreement to the Lender in lawful money of the United States
of America in immediately available funds. Any payment received by the Lender
after 1:00 p.m. (Atlanta, Georgia time) shall be deemed received on the next
Business Day.

                (b) If any payment under this Agreement or the Revolving Note
shall be specified to be made upon a day which is not a Business Day, it shall
be deemed made on the next succeeding day which is a Business Day, and such
extension of time shall in such case be included in computing interest and fees,
if any, in connection with such payment.

                (c) The Company agrees to pay principal, interest, fees and all
other amounts due hereunder or under the Revolving Note without set-off or
counterclaim or any deduction whatsoever.

         Section 1.8       Reimbursement. Whenever the Lender shall sustain or
incur any losses (excluding loss of anticipated profit other than loss resulting
from any interest rate differential) or out-of-pocket expenses in connection
with (i) failure by the Company to borrow or reborrow any LIBOR Advance, or
reborrow any Advance as a LIBOR Advance, in each case, after having given notice
of its intention to borrow in accordance with Section 1.2 hereof (whether by
reason of the election of the Company not to proceed or the non-fulfillment of
any of the conditions set forth in Article 3), or (ii) prepayment of any LIBOR
Advance in whole or in part, or (iii) the failure by the Company to prepay any
Advance after notice of prepayment has been given by the Company to the Lender
in accordance with Section 1.5(a) hereof, the Company agrees to pay to the
Lender, upon the earlier of the Lender's demand or the Maturity Date, an amount
sufficient to compensate the Lender for all such losses and out-of-pocket
expenses. The Lender's good faith determination of the amount of such losses and
out-of-pocket expenses, absent manifest error, shall be binding and conclusive.
The obligations of the Company under this Section shall survive the termination
of this Agreement and the payment of the Revolving Note.

         Section 1.9       Acquisition Advances.

                (a) Acquisition Advance. An Acquisition Advance shall be
available only to finance a Material Acquisition pursuant to the terms and
conditions of this Section 1.9.

The proceeds of any Acquisition Advance shall be limited to an amount not to
exceed one hundred percent (100%) of the cash portion of the purchase price of
the Acquisition to be financed thereby. An Acquisition Advance may be made
either as a Base Rate Advance or a LIBOR Advance in accordance with the terms
and conditions of Section 1.2 hereof with respect to such Advances.

                (b) Consent of the Lender. In the event that the aggregate
purchase price of all Acquisitions made after the date hereof through June 30,
1999, and, thereafter, during the immediately preceding twelve (12) calendar
months shall exceed $15,000,000 after giving effect to a requested Acquisition
Advance, the consent of the Lender shall be required in connection with such
Acquisition Advance. Such consent shall be within the sole discretion of the
Lender.

                (c) Request for Acquisition Advance. In connection with any
Acquisition Advance requiring the consent of the Lender pursuant to Section

         qualified and is in good standing as a foreign corporation and

                     (ii) Each Subsidiary of the Company is a corporation duly
         organized, validly existing and in good standing under the laws of its
         state of incorporation, having the Company as its sole shareholder.
         Each Subsidiary of the Company has the power and authority, to own or
         lease and operate its properties and to carry on its business as now
         being and hereafter proposed to be conducted, and, except as set forth
         on Schedule 3.1(a), is duly qualified and is in good standing as a
         foreign corporation and authorized to do business in each jurisdiction
         in which the character of its properties or the nature of its business
         requires such qualification or authorization.

                (b) Authorization: Enforceability. Each of the Company and its
Subsidiaries has the power and has taken all necessary action to authorize it to
execute, deliver and perform this Agreement and each of the other Loan Documents
to which it is a party in accordance with the terms thereof and to consummate
the transactions contemplated hereby and thereby. This Agreement has been duly
executed and delivered by the Company, and is, and each of the other Loan
Documents to which the Company or any of its Subsidiaries is a party is, a
legal, valid and binding obligation of the Company or such Subsidiary,
enforceable in accordance with its terms.

                (c) Subsidiaries. Except as set forth on Schedule 3.1(c)
attached hereto, the Company has no Subsidiaries. With respect to each
Subsidiary of the Company, Schedule 3.1(c) also sets forth (i) the state of its
incorporation, (ii) all jurisdictions in which the Subsidiary is qualified to do
business as a foreign corporation and (iii) the address of the principal place
of business of such Subsidiary.

                (d) Capital Stock and Related Matters. The authorized capital
stock of the Company together with the number of shares that are currently

all such shares are fully paid and non-assessable. All Persons known to the
Company to be the holders of more than five percent (5%) of such capital stock,
together with a description of such capital stock held by such Person, are
listed on Schedule 3.1(d) attached hereto.

                (e) Compliance with Laws, Other Loan Documents and Contemplated
Transactions. The execution, delivery and performance of this Agreement and each
of the other Loan Documents in accordance with their respective terms and the
consummation of the transactions contemplated hereby and thereby do not and will
not (i) violate any Applicable Law, (ii) conflict with, result in a breach of or
constitute a default under the Articles of Incorporation or By-Laws of the
Company, or under any indenture, agreement or other instrument to which the
Company or any of its Subsidiaries is a party or by which it or any of its
properties may be bound or (iii) result in or require the 


                                       13
<PAGE>   18

creation or imposition of any Lien upon or with respect to any property now
owned or hereafter acquired by the Company except Permitted Liens.

                (f) Real Property. All real property presently leased by the
Company and its Subsidiaries and the name of the lessor of such real property,
is set forth in Schedule 3.1(f). The leases of the Company and each of its
Subsidiaries are valid, enforceable and in full force and effect, and have not
been modified or amended, except as otherwise set forth in Schedule 3.1(f). The
Company, or the appropriate Subsidiary, is the sole holder of the lessee's
interests under each such lease, and has the right to pledge and assign the same
except as qualified in Schedule 3.1(f). Neither the Company or any of its
Subsidiaries has made any pledge or assignment (other than to the Lender) of any
of its rights under such leases except as set forth in Schedule 3.1(f) and, so
far as is known to the Company, except as set forth in Schedule 3.1(f), there is
no default or condition which, with the passage of time or the giving of notice,
or both, would constitute a material default on the part of any party under such
leases. All real property presently owned by the Company is set forth in
Schedule 3.1(h). The Company presently does not own, lease or use any real
property other than as set forth on Schedule 3.1(f) or Schedule 3.1(h).

                (g) Necessary Authorizations. The Company has secured all
Necessary Authorizations, and all such Necessary Authorizations are in full
force and effect and not subject to any pending attack or revocation.

                (h) Title to Properties. Each of the Company and its
Subsidiaries has good, marketable and legal title to, or a valid leasehold
interest in, all of their respective material properties and assets (including,
without limitation, the Accounts), and none of such properties or assets is
subject to any Liens, other than Permitted Liens, which materially detract from
the value of such properties or assets or materially interferes with the
respective business or operations of the Company and its Subsidiaries as
presently conducted or proposed to be conducted. Neither Company nor any of its
Subsidiaries owns any real property other than that listed on Schedule 3.1(h)
attached hereto.

                (i) Taxes. Except as detailed on Schedule 3.1(i) attached
hereto, all federal, state and other tax returns of the Company and each of its
Subsidiaries required by law to be filed have been duly filed, and all federal,
state and other taxes, assessments and other governmental charges or levies upon
the Company and each of its Subsidiaries and any of their respective properties,
income, profits and assets, which are due and payable, have been paid, except
any such sums the payment of which the Company or its Subsidiary is contesting
in good faith by appropriate proceedings and for which adequate reserves have
been provided on the books of the Company or its Subsidiary, as applicable.

                (j) Financial Statements. The Company has furnished, or caused
to be furnished, to the Lender financial statements for the Company and its
Subsidiaries which are complete and correct in all material respects and present
fairly in accordance with GAAP the financial position of the Company as at
September 30, 1996, and the results of operations for the period then ended.
Except as disclosed in such financial statements, the Company has had no
material liabilities required to be reflected in financial statements prepared
in accordance with GAAP, contingent or otherwise, and there are no 


                                       14
<PAGE>   19

material unrealized or anticipated losses of the Company which have not been
heretofore disclosed in writing to the Lender.

                (k) No Adverse Change. Except as set forth on Schedule 3.1(k),
since [March 31, 1998], there has occurred no event which would have a
Materially Adverse Effect.

                (l) Liabilities, Litigation, etc. Except for liabilities
incurred in the normal course of business, neither the Company nor any of its
Subsidiaries has had any material (individually or in the aggregate)
liabilities, direct or contingent, nor any litigation (pending or threatened)
except as disclosed or referred to in the financial statements referred to in
Section 3.1(j) above. Except as disclosed on Schedule 3.1(l), there is no
litigation, legal or administrative proceeding, investigation or other action of
any nature pending or, to the knowledge of the Company, threatened against or
affecting the Company, any of its Subsidiaries or any of its or their respective
properties which involves the possibility of any judgment or liability not fully
covered by insurance that, singly or in the aggregate, could reasonably be
expected to have a Materially Adverse Effect.

                (m) ERISA. The Company and each ERISA Affiliate and each of
their respective Plans are in substantial compliance with ERISA and the Code,
and neither the Company nor any of its ERISA Affiliates has incurred any
accumulated funding deficiency with respect to any such Plan within the meaning
of ERISA or the Code. The Company and each of its ERISA Affiliates have complied
with all requirements of ERISA Sections 601 through 608 and Code Section 4980B.
Neither the Company nor any of its ERISA Affiliates has made any promises of
retirement or other benefits to employees, except as set forth in the Plans. The
Company has not incurred any material liability to the Pension Benefit Guaranty
Corporation in connection with any such Plan. The assets of each such Plan which
is subject to Title IV of ERISA are sufficient to provide the benefits under
such Plan, the payment of which the Pension Benefit Guaranty Corporation would
guarantee if such Plan were terminated, and such assets are also sufficient to
provide all other "benefit liabilities" (as defined in ERISA Section 4001(a)(16)
due under the Plan upon termination. No Reportable Event has occurred and is
continuing with respect to any such Plan. No such Plan or trust created
thereunder, or party in interest (as defined in Section 3(14) of ERISA), or any
fiduciary (as defined in Section 3(21) of ERISA), has engaged in a "prohibited
transaction" (as such term is defined in Section 406 of ERISA or Section 4975 of
the Code) which would subject such Plan or any other Plan of the Company or any
of its ERISA Affiliates, any trust created thereunder, or any such party in
interest or fiduciary, or any party dealing with any such Plan or any such trust
to the penalty or tax on "prohibited transactions" imposed by Section 502 of
ERISA or Section 4975 of the Code. Neither the Company nor any of its ERISA
Affiliates is a participant in or is obligated to make any payment to a
Multiemployer Plan.

                (n) Compliance with Law; Absence of Default. The Company and
each of its Subsidiaries is in compliance with all Applicable Laws the
non-compliance with which would have a Materially Adverse Effect, and no event
has occurred or has failed to occur which has not been remedied or waived, the
occurrence or non-occurrence of which constitutes (i) a Default or (ii) a
default by the Company or any of its Subsidiaries under any other indenture,
agreement or other instrument, or any judgment, decree or order to 


                                       15
<PAGE>   20

which the Company or any of its Subsidiaries is a party or by which the Company
or any of its Subsidiaries or any of its or their properties may be bound, which
default could reasonably be considered to have a Materially Adverse Effect.

                (o) Casualties; Taking of Properties, etc. Since the date of the
most recent financial statements provided to the Lender by the Company, neither
the business nor the properties of the Company has been materially and adversely
affected as a result of any fire, explosion, earthquake, flood, drought,
windstorm, accident, strike or other labor disturbance, embargo, requisition or
taking of property or cancellation of contracts, permits or concessions by any
domestic or foreign government or any agency thereof, riot, activities of armed
forces, or acts of God or of any public enemy.

                (p) Accuracy and Completeness of Information. None of the
financial statements or any written statements delivered to the Lender pursuant
to this Agreement contains, as at the date of delivery thereof, any untrue
statement of material fact nor do such financial statements, and such written
statements, taken as a whole, omit to state a material fact or any fact
necessary to make the statements contained therein not misleading. As of the
Agreement Date, and as supplemented by the Company from time to time pursuant to
Section 5.4(6), Schedule 3.1(p) hereto lists each Material Customer Contract to
which the Company or any of its Subsidiaries is a party.

                (q) Compliance with Regulations G, T, U and X. Neither the
Company nor any of its Subsidiaries is engaged principally or as one of its
important activities in the business of extending credit for the purpose of
purchasing or carrying, and neither the Company nor any of its Subsidiaries own
or presently intend to acquire, any "margin security" or "margin stock" as
defined in Regulations G, T, U, and X (12 C.F.R. Parts 221 and 224) of the Board
of Governors of the Federal Reserve System (herein called "margin stock"). None
of the proceeds of the Revolving Loans will be used, directly or indirectly, for
the purpose of purchasing or carrying any margin stock or for the purpose of
reducing or retiring any Indebtedness which was originally incurred to purchase
or carry margin stock or for any other purpose which might constitute this
transaction a "purpose credit" within the meaning of said Regulations G, T, U
and X.

                (r) Solvency. The Company and each of its Subsidiaries is
Solvent.

                (s) Business. The Company's business includes providing
proprietary databases and related decision-support software and analytical
services to the United States healthcare industry.

                (t) Name of the Company and its Subsidiaries; Principal Place of
Business. Neither the Company nor any of its Subsidiaries has changed its name,
or transacted business under any other name or trade name, within the five (5)
years preceding the Agreement Date, except as disclosed on Schedule 3.1(t)
hereto. The principal place of business of the Company is as set forth in
Section 7.1 hereto.

                (u) Environmental Matters. Except as would not, individually or
in the aggregate, have a Materially Adverse Effect, and except as is described
on Schedule 3.1(u) attached hereto with respect to each of the Properties:


                                       16
<PAGE>   21

                         (i) To the knowledge of the Company, the Properties do
         not contain, in, on or under, including, without limitation, the soil
         and groundwater thereunder, any Hazardous Materials in violation of
         Environmental Laws or in amounts that could give rise to liability
         under Environmental Laws;

                        (ii) To the knowledge of the Company, the Properties and
         all operations and facilities at the Properties are in compliance with
         all Environmental Laws, and to the knowledge of the Company, there is
         no contamination or violation of any Environmental Law which could
         interfere with the continued operation of any of the Properties or
         impair the financial condition of the Company;

                       (iii) The Company has not received from any governmental
         authority any complaint, notice of violation, alleged violation,
         investigation or advisory action or notice of potential liability
         regarding matters of environmental protection or permit compliance
         under applicable Environmental Laws with regard to the Properties, nor
         is the Company aware that any governmental authority is contemplating
         delivering to the Company or any of its Subsidiaries any such notice.
         To the knowledge of the Company, there has been no pending or
         threatened complaint, notice of violation, alleged violation,
         investigation or notice of potential liability under Environmental Laws
         with regard to any of the Properties;

                        (iv) Neither the Company nor any of its Subsidiaries has
         generated, treated, stored, or disposed of any Hazardous Materials at,
         on or under any of the Properties in violation of any Environmental
         Laws or in a manner that could give rise to liability under
         Environmental Laws nor has the Company or any of its Subsidiaries
         transported or disposed of any Hazardous Materials from any of
         the Properties to any other location in violation of any Environmental
         Laws or in a manner that could give rise to liability under
         Environmental Laws;

                         (v) There are no governmental administrative actions or
         judicial proceedings pending under any Environmental Law to which the
         Company or any of its Subsidiaries is a party with respect to any of
         the Properties, nor to the knowledge of the Company, are there any
         consent decrees or other decrees, consent orders, administrative orders
         or other orders or other administrative or judicial requirements
         outstanding under any Environmental Law with respect to any of the
         Properties; and

                        (vi) To the knowledge of the Company, there has been no
         release or threat of release by the Company or any of its Subsidiaries
         of Hazardous Materials into the environment at or from any of the
         Properties, or arising from or relating to the operations of the
         Company, in violation of Environmental Laws or in amounts that could
         give rise to liability under Environmental Laws.

                (v) Patents, Trademarks, Franchises, etc. Except as set forth on
Schedule 3.1(v) attached hereto, neither the Company nor any of its Subsidiaries
owns any registered patents, trademarks, service marks or registered copyrights
and has no pending registration applications with respect to patents,
trademarks, service marks or copyrights. Except as set forth on Schedule 3.1(v),
no other patents, trademarks, service marks or 


                                       17
<PAGE>   22

registered copyrights are necessary for the operation of the business of the
Company or any of its Subsidiaries.

                (w) OSHA. All of the operations of each of the Company and its
Subsidiaries are conducted in material compliance with all applicable rules and
regulations promulgated by the Occupational Safety and Health Administration of
the United States Department of Labor.

                (x) Investment Company Act. Neither the Company nor any of its
Subsidiaries is required to register under the provisions of the Investment
Company Act of 1940, as amended, and neither the entering into or performance by
the Company of this Agreement nor the issuance of the Revolving Note violates
any provision of such Act or requires any consent, approval, or authorization
of, or registration with, any governmental or public body or authority pursuant
to any of the provisions of such Act.

                (y) Year 2000.

                    (i)  The Company has (A) begun analyzing the operations of
         the Company and its Subsidiaries that could be adversely affected by
         failure to become Year 2000 compliant (that is, that computer
         applications, imbedded microchips and other systems will be able to
         perform date-sensitive functions prior to and after December 31, 1999),
         and (B) developed a plan for becoming Year 2000 compliant in a timely
         manner, the implementation of which is on schedule in all material
         respects. The Company reasonably believes that it will become Year 2000
         compliant for its operations and those of its Subsidiaries on a timely
         basis except to the extent that a failure to do so could not reasonably

         of its ERISA Affiliates shall engage in a "prohibited transaction" (as
         such term is defined in Section 406 of ERISA or Section 4975 of the
         Code) which would subject any such Plan, any trust created thereunder,
         any trustee or administrator thereof, or any party dealing with any
         such Plan or trust to the tax or penalty on "prohibited transactions"
         imposed by Section 502 of ERISA or Section 4975 of the Code; or the
         Company or any of its ERISA Affiliates shall enter into or become
         obligated to contribute to a Multiemployer Plan;

                (l) There shall occur any default under any indenture, agreement

                (m) Any Loan Document or provision thereof shall at any time and
         for any reason be declared by a court of competent jurisdiction to be
         null and void, or a proceeding shall be commenced by the Company or any
         Affiliate or by any governmental authority having jurisdiction over the
         Company or any Affiliate seeking to establish the invalidity or
         unenforceability thereof (exclusive of questions of interpretation of

                (b)  Declare the principal of and interest on the Revolving

Lender's intent to require strict adherence to the terms of this Agreement in
the future.

         Section 8.4 Set-Off. In addition to any rights now or hereafter granted
under Applicable Law and not by way of limitation of any such rights, upon the
occurrence of a Default or an Event of Default, the Lender and any subsequent
holder of the Revolving Note are hereby authorized by the Company at any time or
from time to time, without notice to the Company, or to any other Person, any
such notice being hereby expressly waived, to set-off, to appropriate and to
apply any and all deposits (general or special, time or demand, including, but
not limited to, Indebtedness evidenced by certificates of deposit, in each case
whether matured or unmatured) and any other Indebtedness at any time held or
owing by the Lender or such holder to or for the credit or the account of the
Company, as the case may be, against and on account of the obligations and
liabilities of the Company, as the case may be, to the Lender or such holder
under this Agreement, the Revolving Note, and any other Loan Document,
including, but not limited to, all claims of any nature or description arising

declared the principal of and interest on the Revolving Loans and the Revolving

upon prior written notice to the Company. The Company hereby agrees that any
holder of a participation in, and any assignee or transferee of, all or any
portion of any amount owed by the Company under this Agreement and the Revolving
Note (i) shall be entitled to the benefits of the provisions of this Agreement
as a lender hereunder and (ii) may exercise any and all rights of banker's lien,
set-off or counterclaim with respect to any and all amounts owed by the Company

benefit or any legal or equitable right, remedy or other claim under this
Agreement or the Revolving Note.

         Section 8.6 Counterparts. This Agreement may be executed in any number
of counterparts, each of which shall be deemed to be an original, but all such

         Section 8.8  Severability. Any provision of this Agreement which is

Company in connection with the Revolving Loans, including, without limitation,

requirements, are and shall be deemed to be charges made to compensate the

performed and incurred, and to be performed and incurred, by the Lender in
connection with the Revolving Loans, and shall under no circumstances be deemed
to be charges for the use of money. All charges referred to herein shall be
fully earned when due and non-refundable when paid.

         Section 8.10 Headings.  Headings used in this Agreement are for 
convenience only and shall not be used in connection with the interpretation of
any provision hereof.

                                    ARTICLE 9

                                YIELD PROTECTION

         Section 9.1 LIBOR Rate Basis Determination. Notwithstanding anything
contained herein which may be construed to the contrary, if with respect to any
proposed LIBOR Rate Advance for any LIBOR Advance Period, the Lender determines
that deposits in dollars (in the applicable amount) are not being offered to the
Lender in the relevant market for such LIBOR Advance Period, the Lender shall
forthwith give notice thereof to the Company, whereupon until the Lender
notifies the Company that the circumstances giving rise to such situation no
longer exist, the obligations of the Lender to make such types of LIBOR Rate
Advances shall be suspended.

         Section 9.2 Illegality. If any applicable law, rule or regulation, or
any change therein, or any interpretation or change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the Lender with any request or directive (whether or not having the force of
law) of any such authority, central bank or 


                                       35
<PAGE>   40

comparable agency, shall make it unlawful or impossible for the Lender to make,
maintain or fund its LIBOR Rate Advances, the Lender shall so notify the
Company. Before giving any notice to the Company pursuant to this Section 9.2,
the Lender shall designate a different lending office if such designation will
avoid the need for giving such notice and will not, in the judgment of the
Lender, be otherwise disadvantageous to the Lender. Upon receipt of such notice,
notwithstanding anything contained in Article 1 hereof, the Company shall repay
in full the then outstanding principal amount of each affected LIBOR Rate
Advance, together with accrued interest thereon, either (a) on the last day of
the then current LIBOR Advance Period applicable to such LIBOR Rate Advance if
the Lender may lawfully continue to maintain and fund such LIBOR Rate Advance to
such day or (b) immediately if the Lender may not lawfully continue to fund and
maintain such LIBOR Rate Advance to such day; provided, however, that
notwithstanding any provision contained in this Agreement to the contrary, the
Company shall not be required to compensate the Lender for any losses, including
any loss or expenses incurred by reason of the liquidation, reemployment of
deposits or other funds acquired to obtain the LIBOR Rate Advance, incurred as a
consequence of any required conversion of a LIBOR Rate Advance to a Base Rate
Advance as hereinafter provided, as a result of the events described in this
Section. Concurrently with repaying each affected LIBOR Rate Advance,
notwithstanding anything contained in Article 1 hereof, the Company shall borrow
a Base Rate Advance (or the other type of LIBOR Rate Advance, if available) from
the Lender, and the Lender shall make such Advance in an amount such that the
outstanding principal amount of the Revolving Note shall equal the outstanding
principal amount of the Revolving Note immediately prior to such repayment.

         Section 9.3  Increased Costs.

                (a) If any Applicable Law, rule or regulation, or any change
therein, or any interpretation or change in interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof or compliance by the Lender
with any request or directive (whether or not having the any such authority,
central bank or comparable agency:

                   (i) Shall subject the Lender to any tax, duty or other charge
         with respect to its obligation to make LIBOR Rate Advances, or its
         LIBOR Rate Advances, or shall change the basis of taxation of payments
         to the Lender of the principal of or interest on its LIBOR Rate
         Advances or in respect of any other amounts due under this Agreement in
         respect of its LIBOR Rate Advances or its obligation to make LIBOR Rate
         Advances (except for changes in the rate of tax on the overall net
         income of the Lender imposed by the jurisdiction in which the Lender's
         principal executive office is located); or

                  (ii) Shall impose, modify, or deem applicable any reserve
         (including, without limitation, any imposed by the Board of Governors
         of the Federal Reserve System, but excluding any included in an
         applicable LIBOR Reserve Percentage), special deposit, capital
         adequacy, assessment or other requirement or condition against assets
         of, deposits with or for the account of, or commitments or credit
         extended by the Lender, or shall impose on the Lender or the eurodollar
         interbank borrowing market any other condition affecting its obligation
         to make such



                                       36
<PAGE>   41



         LIBOR Rate Advances or its LIBOR Rate Advances; and the result of any
         of the foregoing is to increase the cost to the Lender of making or
         maintaining any such LIBOR Rate Advances, or to reduce the amount of
         any sum received or receivable by the Lender under this Agreement or
         under the Revolving Note with respect thereto, and such increase is not
         given effect in the determination of the LIBOR Rate then,

on the earlier of demand by the Lender or the Maturity Date, the Company agrees
to pay to the Lender such additional amount or amounts as will compensate the
Lender for such increased costs. The Lender will promptly notify the Company of
any event of which it has knowledge, occurring after the date hereof, which will
entitle the Lender to compensation pursuant to this Section 9.3 and will
designate a different lending office if such designation will avoid the need
for, or reduce the amount of, such compensation and will not, in the sole
judgment of the Lender, be otherwise disadvantageous to the Lender.

                (b) A certificate of the Lender claiming compensation under this
Section 11.9 and setting forth the additional amount or amounts to be paid to it
hereunder and calculations therefor shall be conclusive in the absence of
manifest error. In determining such amount, the Lender may use any reasonable
averaging and attribution methods. If the Lender demands compensation under this
Section 9.3, the Company may at any time, upon at least five (5) Business Days'
prior notice to the Lender, prepay in full the then outstanding affected LIBOR
Rate Advances of the Lender, together with accrued interest thereon to the date
of prepayment, along with any reimbursement required under Section 1.8 hereof.
Concurrently with prepaying such LIBOR Rate Advances, the Company shall borrow a
Base Rate Advance, or a LIBOR Rate Advance not so affected, from the Lender, and
the Lender shall make such Advance in an amount such that the outstanding
principal amount of the Revolving Note shall equal the outstanding principal
amount of the Revolving Note immediately prior to such prepayment.

         Section 9.4 Effect On Other Advances. If notice has been given pursuant
to Section 9.1, 9.2 or 9.3 suspending the obligation of the Lender to make any
type of LIBOR Rate Advance, or requiring LIBOR Rate Advances of the Lender to be
repaid or prepaid, then, unless and until such Lender notifies the Company that
the circumstances giving rise to such repayment no longer apply, all Advances
which would otherwise be made by the Lender as to the type of LIBOR Rate
Advances affected shall, at the option of the Company, be made instead as Base
Rate Advances.

         Section 9.5 Capital Adequacy. If after the date hereof, the Lender (or
any Affiliate of the Lender) shall have reasonably determined that the adoption
of any applicable law, governmental rule, regulation or order regarding the
capital adequacy of banks or bank holding companies, or any change therein, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Lender (or any Affiliate of the
Lender) with any request or directive regarding capital adequacy (whether or not
having the force of law) of any such governmental authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on the Lender's (or any Affiliate of the Lender) capital as a consequence of the
Lender's Commitment or Obligations hereunder to a level below that which it
could have achieved but for such adoption, change or compliance (taking into
consideration the Lender's (or any Affiliate of the Lender) policies with
respect to capital adequacy immediately before such adoption, change or
compliance and assuming that the Lender's (or any Affiliate of the Lender)
capital was fully utilized prior to such adoption, 


                                       37
<PAGE>   42

change or compliance), then, upon demand by the Lender, the Company shall
immediately pay to the Lender such additional amounts as shall be sufficient to
compensate the Lender for any such reduction actually suffered; provided,
however, that there shall be no duplication of amounts paid to the Lender
pursuant to this sentence and Section 9.3 hereof. A certificate of the Lender
setting forth the amount to be paid to it by the Company as a result of any
event referred to in this paragraph shall, absent manifest error, be conclusive.

                                   ARTICLE 10

arising from an alleged tort, shall be determined by binding arbitration in
accordance with the Federal Arbitration Act (or if not applicable, the
applicable state law), the rules of practice and procedure for the arbitration
of commercial disputes of J.A.M.S./Endispute or any successor thereof
("J.A.M.S."), and the "special rules" set forth below. In the event of any
inconsistency, the "special rules" shall control. Judgment upon any arbitration
award may be entered in any court having jurisdiction. Any party to this
instrument, agreement or document may bring an action, including a summary or
expedited proceeding, to compel arbitration of any controversy or claim to which
this Agreement and the other Loan Documents applies in any court having
jurisdiction over such action.

         Section 12.2 Special Rules. The arbitration shall be conducted in
Atlanta, Georgia, and administered by J.A.M.S, who will appoint an arbitrator.
If J.A.M.S. is unable or legally precluded from administering the arbitration,
then the American Arbitration Association will serve as administrator. All
arbitration hearings will be commenced within ninety (90) days of the demand for
arbitration. Further, the arbitrator shall only, upon a showing of cause, be
permitted to extend the commencement of such hearing for up to an additional
sixty (60) days.

         Section 12.3 Reservation of Rights. Nothing in this arbitration
provision shall be deemed to (i) limit the applicability of any otherwise
applicable statutes of limitation or repose and any waivers contained in this
Agreement or the other Loan Documents; or (ii) be a waiver by the Lender of the
protection afforded to it, if applicable, by 12 U.S.C. Sec. 91 or any
substantially equivalent state law; or (iii) limit the right of the Lender (a)
to exercise self help remedies such as (but not limited to) setoff, or (b) to
foreclose against any real or personal property collateral, or (c) to obtain
from a court provisional or ancillary remedies such as (but not limited to)
injunctive relief, writ of possession or the appointment of a receiver. The
Lender may exercise such self help rights, foreclose upon such property, or
obtain such provisional or ancillary remedies before, during or after the
pendency of any arbitration proceeding brought pursuant to this Agreement.
Neither this exercise of self help remedies nor the institution or maintenance
of an action for foreclosure or provisional or ancillary remedies shall
constitute a waiver of the right of any party, including the claimant in any
such action, to arbitrate the merits of the controversy or claim occasioning
resort to such remedies.

its Subsidiaries' or subcontractor's plants and facilities which manufacture,
inspect or store products or provide services (or which have done so during the
prior six-month period) sold under any of the Trademarks, and to inspect the
products of and services and quality control records relating thereto upon
reasonable notice to Assignor and as often as may be reasonably requested.

                  4. Representations and Warranties. Assignor covenants and
warrants as follows:

                           (a) A true and complete list of all United States
         trademark and service mark registrations and applications for
         registration (the "U.S. Registrations") owned, held (whether pursuant
         to a license or otherwise) or used by Assignor, in whole or in part, in
         conducting its business is set forth on Schedule A hereto as such
         schedule may be supplemented and amended from time to time.

                           (b) The Trademarks are subsisting and have not been
         adjudged invalid or unenforceable and Assignor is not aware of any
         claim by any third party that the Trademarks are invalid or
         unenforceable.

                           (c) To the best of Assignor's knowledge, each of the
         Trademarks is valid and enforceable.

                           (d) No claim has been made that the practice of any
         of the Trademarks does or may violate the rights of any third person.

                           (e) Assignor is the legal and beneficial owner of the
         Collateral free and clear of any lien, security interest, charge or
         encumbrance, including, 


                                      -3-
<PAGE>   74

         without limitation, pledges, assignments, licenses, shop rights and
         covenants by Assignor not to sue third persons, except for (i) the
         security interest and assignment created by this Agreement and (ii)
         Permitted Liens. No effective financing statement or other instrument
         similar in effect covering all or any part of the Collateral is on file
         in any recording office, except such as may have been filed in favor of
         Assignee relating to this Agreement or for which duly executed
         termination statements have been recorded or delivered to Assignee.

                           (f) This Agreement will create in favor of Assignee a
         valid and perfected first priority security interest in the Collateral
         upon making the filings referred to in clause (g) below.

                           (g) Except for the filing of financing statements
         with the appropriate officer in Fulton County, Georgia under the UCC
         and filings with the United States Patent and Trademark Office, no
         authorization, approval or other action by, and no notice to or filing
         with, any governmental authority or regulatory body is required either
         (i) for the grant by Assignor of the security interest granted hereby
         or for the execution, delivery or performance of this Agreement by
         Assignor or (ii) for the perfection of or the exercise by Assignee of
         its rights and remedies hereunder to the U.S. Registrations.

                           (h) The chief executive office of Assignor is located
         at the address set forth above for Assignor.

                           (i) Except as disclosed on Schedule B attached
         hereto, none of Assignor's Affiliates or Subsidiaries has any right,
         title or interest in any Trademarks.

                  5. New Trademarks and Applications. If, during the term of the
Credit Agreement, Assignor shall obtain rights to any new Trademarks, the
provisions of this Agreement shall automatically apply thereto. With respect to
any new U.S. Registrations, Assignor shall give to Assignee prompt notice
thereof in writing.

                  6. Assignor's Covenants. On a continuing basis and at the
request of Assignee, Assignor shall make, execute, acknowledge and deliver, and
file and record in the proper filing and recording places, all such instruments,
including, without limitation, appropriate financing and continuation statements
and security agreements, and take all such action as may be deemed necessary or
advisable by Assignee to carry out the intent and purposes of this Agreement, or
for assuring and confirming to Assignee the grant or perfection of a security
interest in all Collateral. Without limiting the generality of the foregoing
sentence, Assignor (i) shall not enter into any agreement which would or might
in any way impair or conflict with Assignor's obligations hereunder without
Assignee's prior written consent; (ii) upon the written request of 


                                      -4-
<PAGE>   75

Assignee, shall use its best efforts to obtain any necessary consents of third
parties to the grant or perfection of a security interest to Assignee with
respect to the Collateral; (iii) authorizes Assignee in its sole discretion to
modify this Agreement without first obtaining Assignor's approval of or
signature to such modification by amending Schedule A thereof to include a
reference to any right, title or interest in any existing U.S. Registration and
any U.S. Registration acquired by Assignor after the execution hereof or to
delete any reference to any right, title or interest in any U.S. Registration in
which Assignor no longer has or claims any right, title or interest; (iv) shall,
from time to time upon Assignee's request, cause its books and records to be
marked with such legends or segregated in such manner as Assignee may reasonably
specify, and take or cause to be taken such other action and adopt such
procedures as Assignee may reasonably specify to give notice of or to perfect
the security interest in the Collateral intended to be created hereby; (v) shall
at all times keep at least one complete set of its records concerning
substantially all of the Trademarks at its chief executive office as set forth
above and will not change the location of its chief executive office or such
records without giving Assignee at least thirty (30) days' prior written notice
thereof; (vi) shall promptly, following its becoming aware thereof, notify
Assignee of the institution of, or any adverse determination in, any proceeding
in the United States Patent and Trademark Office or any United States or foreign
court regarding Assignee's claim of ownership in any of the Collateral; (vii)
shall promptly notify Assignee of the filing of an application for registration
of any trademark; (viii) shall not permit the inclusion in any contract to which
it becomes a party of any provisions which could or might in any way impair or
prevent the creation of a security interest in Assignor's rights and interest in
any property included within the definition of the Collateral acquired under
such contracts; (ix) shall properly maintain and care for the Collateral; (x)
shall not grant any security interest in any Collateral (other than Permitted
Liens) except in the name of Assignee; (xi) shall not sell, license, or contract
for sale or otherwise dispose of any Collateral except as may be permitted by
the Credit Agreement; (xii) upon any officer of Assignor obtaining knowledge
thereof, shall promptly notify Assignee of any event which materially adversely
affects the value of any Collateral, the ability of Assignor or Assignee to
dispose of any of the Trademarks or the rights and remedies of Assignee in
relation thereto including, without limitation, the levy of any legal process
against any of the Collateral; (xiii) until Assignee exercises its rights to
make collection, shall diligently keep reasonable records respecting the
Collateral; (xiv) shall promptly notify Assignee of any suspected infringement
of any of the Trademarks by any third party and of all steps, including the
commencement and course of litigation, taken to remedy such infringement; and
(xv) shall use proper statutory notice in conjunction with each of the U.S.
Registrations.

                  7. Amounts Payable in Respect of the Trademarks. Except as
otherwise provided in this Section 7 or in the Credit Agreement, Assignor shall
continue to collect, at its own expense, all amounts due or to become due to
Assignor in respect of the Trademarks. Upon the occurrence and during the
continuance of an Event of 


                                      -5-
<PAGE>   76

Default, Assignee is hereby given full power and authority, without notice or
demand, (i) to notify any and all obligors of Assignor with respect to any
Trademark obligation which Assignor, except for the execution hereof, could ask
for, and (ii) to demand, take, collect, sue for and receive for its own use all
amounts due or to become due Assignor in respect of the Trademarks, and in
connection therewith to enforce all rights and remedies with respect to any
Trademark which Assignor could enforce if this Agreement had not been made; and
Assignor hereby ratifies any action which Assignee shall lawfully take to
enforce Assignee's rights hereunder. Whether or not Assignee shall have so
notified any obligors, Assignor shall at its expense render all reasonable
assistance to Assignee in enforcing claims against such obligors.

                  8. Trademark Applications, Renewal and Litigation. Assignor
shall have the duty to prosecute diligently any application for trademark
registration of the U.S. Registrations specifically identified in Schedule A
annexed hereto pending as of the date of this Agreement or thereafter during the
term of the Credit Agreement, to make U.S. application on any existing or future
unregistered but registrable Trademark (except those having negligible
commercial value) and to preserve, renew and maintain all Trademarks as to which
a security interest has been granted pursuant to this Agreement. Any expenses
incurred in connection with such an application, or in protecting, maintaining
or preserving the Trademarks, shall be borne by Assignor.

                  Assignor shall have the right and obligation to commence and
diligently prosecute in its own name, as real party in interest, for its own
benefit and at its own expense, such suits, proceedings or other actions for
infringement, or other damage or opposition or cancellation proceedings as are
reasonable to protect any of the Trademarks. However, no such suit, proceeding
or other action shall be settled or voluntarily dismissed, nor shall any party
be released or excused of any claims of or liability for infringement, without
the prior written consent of Assignee. Assignor shall indemnify and hold
harmless Assignee for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
(including reasonable attorneys' fees) of any kind whatsoever which may be
imposed on, incurred by or asserted against Assignee in connection with or in
any way arising out of such suits, proceedings or other actions other than
actions caused by Assignee's gross negligence or willful misconduct.

                  9. Certain Remedies. If any Event of Default shall have
occurred and be continuing:

                           (a) Assignee may exercise in respect of the
         Collateral, in addition to other rights and remedies provided for
         herein or otherwise available to it, all the rights and remedies of a
         secured party in default under the UCC in effect in the State of
         Georgia at that time (whether or not the UCC applies to the affected
         Collateral) and also may (i) require Assignor to, and Assignor hereby
         agrees 

                                      -6-
<PAGE>   77

         that it will at its expense and upon request of Assignee forthwith,
         assemble all or part of the Collateral as directed by Assignee and make
         it available to Assignee at a place to be designated by Assignee which
         is reasonably convenient to both parties; (ii) without notice except as
         specified below, sell the Collateral or any part thereof in one or more
         parcels at public or private sale, at any of Assignee's offices or
         elsewhere, for cash, on credit or for future delivery, and upon such
         other terms as Assignee may deem commercially reasonable; (iii) occupy
         any premises owned or leased by Assignor where the Collateral or any
         part thereof is located for a reasonable period in order to effectuate
         its rights and remedies hereunder or under law, without obligation to
         Assignor in respect of such occupation; and (iv) exercise any and all
         rights and remedies of Assignor under or in connection with the
         contracts related to Collateral or otherwise in respect of the
         Collateral, including, without limitation, any and all rights of
         Assignor to demand or otherwise require payment of any amount under, or
         performance of any provision of, such contracts. Assignor agrees that,
         to the extent notice of sale shall be required by law, at least ten
         (10) days' written notice to Assignor of the time and place of any
         public sale or the time after which any private sale is to be made
         shall constitute reasonable notification. Assignee shall not be
         obligated to make any sale of Collateral regardless of notice of sale
         having been given. Assignee may adjourn any public or private sale from
         time to time by announcement at the time and place fixed therefor, and
         such sale may, without further notice, be made at the time and place to
         which it was so adjourned.

                           (b) Any cash held by Assignee as Collateral and all
         cash proceeds received by Assignee in respect of any sale of,
         collection from, or other realization upon all or any part of the
         Collateral may, in the discretion of Assignee, be held by Assignee as
         collateral for, and then or at any time thereafter applied in whole or
         in part by Assignee against, all or any part of the obligations of
         Assignor to the Lender in such order as is provided in the Credit
         Agreement. Any surplus of such cash or cash proceeds held by Assignee
         and remaining after payment in full of all such Obligations shall be
         paid over to Assignor or to whomsoever may be lawfully entitled to
         receive such surplus.

                  10. Power of Attorney. Assignor hereby authorizes and empowers
Assignee, upon the occurrence and during the continuation of an Event of
Default, to make, constitute and appoint any officer or agent of Assignee as
Assignor's true and lawful attorney-in-fact, with power (i) to endorse
Assignor's name on all applications, documents, papers and instruments necessary
for Assignee in the use or maintenance of the Collateral, (ii) to take any other
actions with respect to the Collateral, including without limitation,
commencement or continuation of any litigation or administrative proceeding, as
Assignee deems in its best interest, (iii) to grant or issue an exclusive or


                                      -7-
<PAGE>   78

non-exclusive license to the Trademarks to anyone, or (iv) to assign, pledge,
convey or otherwise transfer title in or dispose of the Collateral to anyone.

                  11. Amendments, etc. No amendment or waiver of any provision
of this Agreement nor consent to any departure by Assignor herefrom, shall in
any event be effective unless the same shall be in writing and signed by the
parties hereto, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given, except as
provided in Section 6, in which case the writing need only be signed by
Assignee.

                  12. Address for Notices. All notices and other communications
to any party provided for hereunder shall be in writing (including
telecommunications) and mailed or transmitted or delivered to such party,
addressed to it at the address first stated herein for such party, or as to
either party at such other address as shall be designated by such party in a
written notice to each other party complying as to delivery with the terms of
this Section. All such notices and other communications shall, when mailed,
telegraphed, telexed or cabled, be effective as provided in Section 8.1 of the
Credit Agreement.

                  13. Continuing Security Interest; Transfers by the Lender.
This Agreement shall create a continuing security interest in the Collateral and
shall (i) remain in full force and effect until the indefeasible payment in full
of all of the obligations of Assignor to the Lender, (ii) be binding upon
Assignor, its successors and assigns and (iii) inure to the benefit of Assignee,
and its successors, transferees and assigns. Without limiting the generality of
the foregoing clause (iii), Assignee may assign or otherwise transfer any
obligations held by it, and such other benefits in respect thereof granted to it
herein or otherwise, to any other person or entity, subject, however, to the
provisions of Section 8.5 of the Credit Agreement. Upon the indefeasible payment
in full of all of the obligations of Assignor to the Lender, the security
interest granted hereby shall terminate and all rights to the Collateral shall
revert to Assignor, subject to any disposition thereof which may have been made
by Assignee pursuant hereto or pursuant to the Credit Agreement. Upon any such
termination, Assignee shall, at Assignor's expense, execute and deliver to
Assignor such documents as Assignor shall reasonably request to evidence such
termination.

                  14. Cumulative Remedies; Effect on Credit Agreement. All of
Assignee's rights and remedies with respect to the Collateral, whether
established hereby or by the Credit Agreement, or by any other agreements or by
law shall be cumulative and may be exercised singularly or concurrently.
Assignor hereby acknowledges and agrees that this Agreement is not intended to
limit or restrict in any way the rights and remedies of Assignee under the
Credit Agreement and the other Loan Documents, but rather is intended to
facilitate the exercise of such rights and remedies.

                                      -8-
<PAGE>   79

                  15. Counterparts. This Agreement may be executed in any number
of counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument.

                  16. Severability. The provisions of this Agreement are
severable, and if any clause or provision shall be held invalid or unenforceable
in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such clause or provision
in any other jurisdiction, or any other clause or provision of this Agreement in
any jurisdiction.

                  17. Governing Law; Terms. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF GEORGIA (DETERMINED
WITHOUT REFERENCE TO PRINCIPLES OF CONFLICTS OF LAWS).

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed by their respective officers thereunder duly
authorized, as of the date first above written.

               AMENDED AND RESTATED REVOLVING LOAN PROMISSORY NOTE


                                                            AS OF JUNE ___, 1998
                                                                ATLANTA, GEORGIA



                      FOR VALUE RECEIVED, the undersigned, MEDIRISK, INC., a
Delaware corporation (the "Borrower"), unconditionally promises to pay to the
order of NATIONSBANK, N.A. (hereinafter, together with its successors and
assigns, called the "Lender"), at the principal office of the Lender located in
Atlanta, Georgia, or such other place as the Lender may designate in writing to
the Borrower, the principal sum of TWENTY-FIVE MILLION AND NO/100s Dollars
($25,000,000.00), or, if less, so much thereof as may from time to time be
advanced by the Lender to the Borrower hereunder, plus interest as hereinafter
provided.

                      All capitalized terms used herein shall have the meanings
ascribed to them in that certain Credit Agreement (as hereafter amended from
time to time, the "Credit Agreement") of even date herewith between the Borrower
and the Lender, except to the extent such capitalized terms are otherwise
defined or limited herein.

              Section 1.  Manner of Borrowing Revolving Loans.

                      (a) Advances. Advances hereunder shall be made in
accordance with Section 1.2 of the Credit Agreement.

                      (b) Amount of Advance. Notwithstanding any term or
provision of this Note which may be construed to the contrary, each Base Rate
Advance shall be in a principal amount of no less than $250,000 and in integral
multiples of $5,000, and each LIBOR Advance shall be in a principal amount of no
less than $500,000 and in integral multiples of $100,000.

                      (c) Revolving Loans. Subject to the terms and conditions

principal amount above stated, repay all or any portion thereof, and reborrow up
to such amount on a revolving basis. Such borrowings, to the extent not
evidenced by other notes, shall be evidenced by this Note and shall be subject
to its terms and the terms of the Credit Agreement.

                      (d) Revolving Loans in Excess of Advance Rate. If at any
time the Revolving Loans outstanding exceed the Advance Rate, or any other
applicable limitation set forth in the Credit Agreement, such Revolving Loans

<PAGE>   99



constitute Obligations that are secured by the Collateral and are entitled to
all benefits thereof.

              Section 2.  Repayment.

                      (a) The principal balance of the Revolving Loans then
outstanding shall be due and payable in full on the Maturity Date.
Notwithstanding the foregoing, however, in the event the Revolving Loans
outstanding shall at any time and for any reason exceed the Advance Rate, the
Borrower shall immediately pay to the Lender an amount equal to the difference
between the Revolving Loans and the Advance Rate, which payment shall constitute
a pro rata prepayment of the Revolving Loans evidenced by this Note.

                      (b) Prepayments of this Note may be made only as provided
in the Credit Agreement.

              Section 3. Interest. The Borrower shall pay interest on the daily
outstanding principal balance of this Note in accordance with Section 1.3 of the
Credit Agreement. Interest on each Advance hereunder shall be calculated on the
basis of three hundred and sixty days per year for the actual number of days
elapsed, and, to the extent accrued, shall be paid in arrears by the Borrower
monthly on the last day of each month, commencing on August 1, 1998, until the
principal amount of this Note has been paid in full. The entire principal amount
hereof, together with all accrued and unpaid interest hereon, shall be due and
payable on the Maturity Date.

              Section 4. Upon Default. If an Event of Default shall have
occurred and shall be continuing, the Lender shall have the option (but shall
not be required to give prior notice thereof to the Borrower, to accelerate the
maturity of this Note, or exercise any other rights or remedies hereunder in
connection with this right) to charge interest on the outstanding principal
balance of this Note at the Default Rate from the date of such Event of Default.
In addition, upon the occurrence and during the continuance of an Event of
Default, the Lender shall have all the rights and remedies set forth in the
Credit Agreement.

hereon shall be payable in lawful money of the United States of America, at the
Lender's principal office in Atlanta, Georgia, or at such other place as the
Lender may designate in writing to the Borrower. All payments hereunder received
from the Borrower by the Lender shall be applied to the Obligations as set forth
in the Credit Agreement.

              Section 6. Collateral. This Note is secured by Security Documents 
of even date herewith between the Lender, the Borrower or its Subsidiaries.

              Section 7.  Fees.  All parties liable for the payment of this Note

against liability for the payment of state intangible, documentary and recording
taxes, and other taxes (including interest and penalties, if any) which may be
determined to be payable with respect to this transaction.

              Section 8. Interest. In no event shall the amount of interest due
or payable hereunder exceed the maximum rate of interest allowed by Applicable
Law, and in the event any such payment is inadvertently paid by the Borrower or
inadvertently received by the Lender, then such excess sum shall be credited as
a payment of principal, unless the Borrower shall notify the Lender, in writing,
that the Borrower elects to have such excess sum returned to it forthwith. It is
the express intent hereof that the Borrower not pay and the Lender not receive,
directly or indirectly, in any manner whatsoever, interest in excess of that

              Section 9.  Remedies.

                      (a) The remedies of the Lender as provided herein and in
any Loan Documents or other documents governing or securing repayment hereof
shall be cumulative and concurrent and may be pursued singly, successively or
together, at the sole discretion of the Lender and may be exercised as often as
occasion therefor shall arise.

                      (b) No act of omission or commission of the Lender,
including specifically (but without limitation) any failure to exercise any
right, remedy or recourse, shall be effective unless set forth in a written
document executed by the Lender, and then only to the extent specifically
recited therein. A waiver or release with reference to one event shall not be
construed as continuing, as a bar to, or as a waiver or release of any
subsequent right, remedy or recourse as to any subsequent event.

                      (c) The Borrower hereby (a) waives demand, presentment of
payment, notice of nonpayment, protest, notice of protest and all other notice,
filing of suit and diligence in collecting this Note, or in enforcing any of its
rights under any guaranties securing the repayment hereof; (b) agrees to any
substitution, addition, or release of any party or Person primarily or
secondarily liable hereon; (c) agrees that the Lender shall not be required
first to institute any suit, or to exhaust its remedies against the Borrower or
any other Person or party to become liable hereunder, or against any Collateral
in order to enforce payment of this Note; (d) consents to any extension,
rearrangement, renewal or postponement of time of payment of this Note and to
any other indulgence with respect hereto without notice, consent or
consideration to any of them; and (e) agrees that, notwithstanding the
occurrence of any of the foregoing (except with the express written release by
the Lender or any such Person), the Borrower shall be and remain directly and
primarily liable for all sums due under this Note.

Note.

              (c) Unless expressly set forth herein, all contracts and contract
rights of the Company shall constitute Assigned Contracts and shall constitute
part of the Collateral.

verify the validity, amount or any other matter relating to any Accounts by
mail, telephone or otherwise.

              (b) Delivery of Instruments. In the event any of the Collateral
becomes evidenced by a promissory note, trade acceptance or any other
instrument, the Company shall immediately thereafter deliver such instrument to
the Lender, appropriately endorsed to the Lender.

              (c) Defense of Title. The Company shall at all times be the sole
owner of each and every item of Collateral and shall defend, at its sole cost
and expense, its title in and to, and the Security Interest of the Lender in,
the Collateral against the claims and demands of all Persons.

              (d) Maintenance of Collateral. The Company shall maintain all
physical property that constitutes Collateral in good and workable condition,
with reasonable allowance for wear and tear, and shall exercise proper custody
over all such property.

              (e) Insurance. The Company shall, at its own expense, maintain
insurance with respect to the Collateral in such amounts, against such risks, in
such form and with such insurers, as set forth in the Credit Agreement.

              (f) Location of Office. The Company's chief executive office,
principal place of business and its books and records relating to the Collateral
shall continue to be kept at the address of the Company set forth above, and the
Company shall not change the location of such office and place of business or
such books and records without giving the Lender thirty (30) days' prior written
notice thereof.

              (g) Location of Collateral. All Inventory, other than Inventory in
transit to any such location, and all Equipment shall at all times be kept by
the Company at the locations set forth on Schedule 2(f), and shall not, without
the thirty (30) days' prior written notice to the Lender, be removed therefrom
except in connection with sales thereof in the ordinary course of business.

              (h) Change of Name, Structure, Etc. Without giving the Lender

              (k) Other Information. The Company shall furnish to the Lender
such other information with respect to the Collateral as the Lender may
reasonably request from time to time.

              (l) Payments Directly to Lender. The Lender may at any time and
from time to time following the occurrence and during the continuation of an
Event of Default notify, or request the Company to notify, in writing or
otherwise, any account debtor or other obligor with respect to any one or more
of the Accounts or Assigned Contracts to make payment to the Lender or any agent
or designee of the Lender directly, at such address as may be specified by the
Lender. If, notwithstanding the giving of any notice, any account debtor or
other such obligor shall make payment to the Company, the Company shall hold all
such payments it receives in trust for the Lender, without commingling the same
with other funds or property of or held by the Company, and shall promptly
deliver the same to the Lender, or any such agent or designee, immediately upon
receipt by the Company in the identical form received, together with any
necessary endorsements.

              (m) Sale of Collateral. Except as permitted under the terms of the
Credit Agreement, the Company shall not sell, transfer, convey or dispose of any
Collateral outside the ordinary course of its business; provided, however, that
the Company may dispose of its Inventory in the ordinary course of its business
so long as no Default or Event of Default shall have occurred. The inclusion of
"proceeds" of the Collateral under the Security Interest shall not be deemed a
consent by the Lender to any other sale or other disposition of any part or all
of the Collateral.

              (n) Proceeds of Collateral. The Company shall account fully and
faithfully for, and, following the occurrence and during the continuation of an
Event of Default, upon the Lender's request, promptly pay or turn over to the
Lender, proceeds in whatever form received in disposition in any manner of any
of the Collateral. To the extent practicable, the Company shall at all times
keep the Collateral and proceeds thereof separate and distinct from other
property of the Company and shall keep accurate and complete records of the
Collateral and proceeds thereof.

              SECTION 6. THE LENDER APPOINTED ATTORNEY-IN-FACT. The Company
hereby irrevocably appoints the Lender the Company's attorney-in-fact, with full
authority in the place and stead of the Company and in the name of the Company
or otherwise, following the occurrence and during the continuation of an Event
of Default from time to time in the Lender's discretion, to take any action and
to execute any instrument or document which the Lender may deem necessary or
advisable to accomplish the purposes of this Agreement and to exercise any
rights and remedies the Lender may have under this Agreement or Applicable Law,
including, without limitation: (i) to obtain and adjust insurance required to be
maintained pursuant to Section 5(e) hereof; (ii) to ask, demand, collect, sue
for, recover, compromise, receive and give acquittance and receipts for moneys
due and to become due under or in respect of any of the Collateral, including,
without limitation, any Account; (iii) to receive, endorse and collect any
drafts or other instruments, documents and chattel paper, in connection with
clause (i) or (ii) above; (iv) to sell or assign any Account upon such terms,
for such amount and at such time or times as the Lender may deem advisable, to
settle, adjust, compromise, extend or renew any Account or to discharge and
release any Account; and (v) to file any claims or take any action or institute
any proceedings which the Lender may deem necessary or desirable for the
collection of any of the Collateral or otherwise to enforce the rights of the
Lender with respect to any of the Collateral. The power-of-attorney granted
hereby shall be irrevocable and coupled with an interest.

              SECTION 7. THE LENDER MAY PERFORM. If the Company fails to perform
any agreement contained herein, the Lender may, without notice to the Company,
itself perform, or cause performance of, such agreement, and the expenses of the
Lender incurred in connection therewith shall be payable by the Company under
Section 12 hereof.

              SECTION 8. THE LENDER'S DUTIES. The powers conferred on the Lender
hereunder are solely to protect its interest in the Collateral and shall not
impose any duty upon the Lender to exercise any such powers. Except for the safe
custody of any Collateral in its possession and the accounting for moneys
actually received by it hereunder, the Lender shall have no duty as to any
Collateral. The Lender 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 the Lender accords its own property;
it being understood that the Lender shall be under no obligation to take any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral, but may do so at its option, and all reasonable
expenses incurred in connection therewith shall be for the sole account of the
Company and shall be added to the Obligations.

              SECTION 9. REMEDIES. The Lender may take any or all of the
following actions upon the occurrence and during the continuation of an Event of
Default.

              (a)     Inventory and Equipment.

                    (i) Entry. The Lender may enter upon any premises on which
              Inventory or Equipment may be located and, without resistance or
              interference by the Company, take physical possession of any or
              all thereof and maintain such possession on such premises or move
              the same or any part thereof to such other place or places as the
              Lender shall choose, without being liable to the Company on
              account of any loss, damage or depreciation that may occur as a
              result thereof, other than for actions that were not taken in good
              faith.

                   (ii) Assembly. The Company shall, upon request of and without
              charge to the Lender, assemble the Inventory and Equipment and
              maintain or deliver it into the possession of the Lender or any
              agent or representative of the Lender at such place or places as
              the Lender may reasonably designate.

                  (iii) Warehousing. The Lender may, at the expense of the
              Company, cause any of the Inventory and Equipment to be placed in
              a public or field warehouse, and the Lender shall not be liable to
              the Company on account of any loss, damage or depreciation that
              may occur as a result thereof, other than for actions that were
              not taken in good faith.

              (b)     Use of Premises and Intellectual Property. The Lender 
              may:

                    (i) without notice, demand or other process, and without
              payment of any rent or any other charge enter any of the Company's
              premises and, without breach of the peace, until the Lender
              completes the enforcement of its rights in the Collateral, take
              possession of such premises or place custodians in exclusive
              control thereof, remain on such premises and use the same and any
              of the Company's equipment; and

                   (ii) in the exercise of the rights of the Lender under this
              Agreement, without payment or compensation of any kind, use any
              and all trademarks, trade


                                        7

<PAGE>   109



              styles, trade names, patents, patent applications, licenses,
              franchises and the like to the extent of the rights of the Company
              therein, and the Company hereby grants a license to the Lender for
              this purpose.

              (c) Lock Boxes. The Lender may establish or cause to be
established one or more lock boxes or other arrangement for the deposit of
proceeds of Accounts, and, in such case, the Company shall cause to be forwarded
to the Lender at the Lender's office set forth above, on a daily basis,
collection reports in form and substance satisfactory to the Lender.

              (d) Rights as a Secured Creditor. The Lender may exercise all of
the rights and remedies of a secured party under the Uniform Commercial Code and
under any other Applicable Law, including, without limitation, the right,
without notice except as specified below and with or without taking possession
thereof, to sell the Collateral or any part thereof in one or more parcels at
public or private sale at any location chosen by the Lender, for cash, on credit
or for future delivery, and at such price or prices and upon such other terms as
the Lender may deem commercially reasonable. The Company agrees that, to the
extent notice of sale shall be required by law, at least ten (10) days' notice
to the Company of the time and place of any public sale or the time after which
any private sale is to be made shall constitute reasonable notification, but
notice given in any other reasonable manner or at any other reasonable time
shall constitute reasonable notification. The Lender shall not be obligated to
make any sale of Collateral regardless of notice of sale having been given. The
Lender may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefor, and such sale may, without further notice,
be made at the time and place to which it was so adjourned. The Lender may bid
all or any portion of the Obligations at any such sale.

              (e) Waiver of Marshaling. The Company hereby waives any right to
require any marshaling of assets and any similar right.

              (f) Appointment of Receiver. The Lender shall be entitled to the
appointment of a receiver, without notice of any kind whatsoever and without
regard to the adequacy of any security for the Obligations or the solvency of
any party bound for its payment, to take possession of all or any portion of the
Collateral and the business operations of the Company and to exercise such power
as the court shall confer upon such receiver.

              (g) Accounts/Assigned Contracts. The Lender shall have the
exclusive right to assert, either directly or on behalf of the Company, any and
all rights and claims the Company may have under any Accounts and any of the
Assigned Contracts as the Lender may deem proper and to receive and collect any
and all Accounts and Assigned Contracts and any and all rent, fees, damages,
awards and other monies arising thereunder or resulting therefrom and to apply
the same on account of any of the Obligations.

              SECTION 10. APPLICATION OF PROCEEDS. All proceeds from each sale
of, or other realization upon, all or any part of the Collateral following an
Event of Default, and all insurance proceeds payable by reason of any damage or
destruction of any of the Collateral, shall be applied or paid over as follows:

              (a) First: to the payment of all costs and expenses incurred in
connection with such sale or other realization, including reasonable attorneys'
fees if the Lender endeavored to collect the Obligations by or through an
attorney at law;


                                        8

<PAGE>   110



              (b) Second: to the payment of the accrued interest upon the
Revolving Loans as provided in the Credit Agreement;

              (c) Third: to the payment of the outstanding principal of the
Revolving Loans as provided in the Credit Agreement;

              (d) Fourth: to the payment of the remaining outstanding
Obligations as provided in the Credit Agreement; and

              (e) Fifth: the balance (if any) of such proceeds shall be paid to
the Company or to whomsoever may be legally entitled thereto.

The Company shall remain liable and shall pay, on demand, any deficiency
remaining in respect of the Obligations, together with interest thereon at a
rate per annum equal to the highest rate then payable under the Credit Agreement
on such Obligations, which interest shall constitute part of the Obligations.

              SECTION 11. RIGHTS CUMULATIVE. The rights and remedies of the
Lender under this Agreement, the Credit Agreement and the other Loan Documents
shall be cumulative and not exclusive of any rights or remedies which it would
otherwise have, including, but not limited to, those rights afforded by the
Uniform Commercial Code and other Applicable Laws. In exercising its rights and
remedies the Lender may be selective, and no failure or delay by the Lender in
exercising any right shall operate as a waiver of it, nor shall any single or
partial exercise of any power or right preclude its other or further exercise or
the exercise of any other power or right.

              SECTION 12. EXPENSES. The Company shall pay, on demand, all
reasonable out-of-pocket expenses incurred by the Lender in connection with: (a)
the negotiation, preparation, execution, delivery and administration of this
Agreement and any document or instrument evidencing any of the Obligations
whenever the same shall be executed and delivered, including all appraisers'
fees, search fees, recording fees, intangibles and stamp taxes payable by the
Lender with respect to the Obligations and this Agreement and the Security
Interest created hereby and the fees and disbursements of counsel for the
Lender, and of each local counsel retained by the Lender; (b) the restructuring,
refinancing or "workout" of the transactions contemplated hereby and of the
Obligations, and the preparation, negotiation, execution and delivery of any
waiver, amendment or consent by the Lender relating to this Agreement or the
Obligations, including, without limitation, the fees, out-of-pocket expenses and
other disbursements of counsel to the Lender; (c) the collection or enforcement
of the Obligations including reasonable fees and disbursements of counsel to the
Lender if such collection or enforcement is done through or by an attorney; and
(d) the exercise by the Lender of any right or remedy granted to it under this
Agreement whether or not a Default or Event of Default has occurred, including,
without limitation, the expenses incurred by the Lender in connection with the
collection of Accounts directly from account debtors.

              SECTION 13. AMENDMENTS, ETC. No amendment or waiver of any
provision of this Agreement nor consent to any departure by the Company here
from shall in any event be effective unless the same shall be in writing and
signed by the parties hereto, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given.

              SECTION 14. NOTICES. Unless otherwise provided herein,
communications provided for hereunder shall be in writing and shall be mailed,
telecopied or delivered, to each party at


                                        9

<PAGE>   111



the address specified for such party in the Credit Agreement. All such notices
and other communications to the Company shall be effective upon satisfaction of
the conditions set forth for similar notices in the Credit Agreement.

              SECTION 15. CONTINUING SECURITY INTEREST. This Agreement shall
create a continuing security interest in the Collateral and shall (i) remain in
full force and effect until indefeasible payment in full of the Obligations,
(ii) be binding upon the Company, its successors and assigns and (iii) inure the
benefit of the Lender, and its successors and assigns. The Company's successors
and assigns shall include, without limitation, a receiver, trustee or
debtor-in-possession thereof or therefor. Upon the indefeasible payment in full
of all of the Obligations, the Security Interest granted hereby shall terminate
and all rights to the Collateral shall revert to the Company. Upon any such
termination, the Lender shall at the Company's expense, execute and deliver to
the Company such documents as the Company shall reasonably request to evidence
such termination.

              SECTION 16. APPLICABLE LAW; SEVERABILITY. THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA
APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE
(WITHOUT REGARD TO ANY CONFLICT OF LAWS PROVISIONS THAT INDICATE THE
APPLICABILITY OF ANY OTHER LAWS). Whenever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under Applicable Law, but if any provision of this Agreement shall be prohibited
by or invalid under Applicable Law, such provisions shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provisions or the remaining provisions of this Agreement.

              SECTION 17. LITIGATION/WAIVERS. (a) THE LENDER AND THE COMPANY
BOTH ACKNOWLEDGE AND AGREE THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS
AGREEMENT OR THE RELATIONSHIP OF THE COMPANY AND THE LENDER ESTABLISHED HEREBY
AND THE DOCUMENTS AND INSTRUMENTS EVIDENCING THE OBLIGATIONS WOULD BE BASED UPON
DIFFICULT AND COMPLEX ISSUES. ACCORDINGLY, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH OF THE LENDER AND THE COMPANY HEREBY WAIVES ITS RESPECTIVE
RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN
ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST THE
COMPANY OR THE LENDER ARISING OUT OF THIS AGREEMENT, THE OBLIGATIONS OR ANY
OTHER DOCUMENT EXECUTED AND DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR IN
CONNECTION WITH THE COLLATERAL OR THE SECURITY INTEREST THEREIN OR BY REASON OF
ANY OTHER CAUSE OR DISPUTE WHATSOEVER BETWEEN THE COMPANY AND THE LENDER OF ANY
KIND OR NATURE.

              (b) THE COMPANY AND THE LENDER EACH HEREBY AGREE THAT THE FEDERAL
COURT OF THE NORTHERN DISTRICT OF GEORGIA, OR AT THE OPTION OF LENDER, ANY STATE
COURT LOCATED IN FULTON COUNTY, GEORGIA, SHALL HAVE JURISDICTION TO HEAR AND
DETERMINE ANY CLAIMS OR DISPUTES BETWEEN THE COMPANY AND THE LENDER, PERTAINING
DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE OBLIGATIONS OR TO ANY MATTER
ARISING THEREFROM, THE COLLATERAL OR THE SECURITY INTEREST THEREIN OR ANY OTHER
DOCUMENT EXECUTED AND DELIVERED IN CONNECTION HEREWITH OR THEREWITH. THE COMPANY
EXPRESSLY SUBMIT


                                       10

<PAGE>   112



AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR PROCEEDING
COMMENCED IN SUCH COURTS. THE CHOICE OF FORUM SET FORTH IN THIS PARAGRAPH SHALL
NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE LENDER OR THE
ENFORCEMENT BY THE LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER
APPROPRIATE JURISDICTION.

              (c) FURTHER, THE COMPANY WAIVES (I) ANY NOTICE PRIOR TO THE TAKING
POSSESSION OR CONTROL OF THE COLLATERAL OR ANY POSTING OF ANY BOND OR SECURITY
WHICH MIGHT BE REQUIRED BY ANY COURT PRIOR TO ALLOWING THE LENDER TO EXERCISE
ANY OF THE LENDER'S REMEDIES SET FORTH HEREIN, INCLUDING THE ISSUANCE OF AN
IMMEDIATE WRIT OF POSSESSION AND (II) THE BENEFIT OF ALL VALUATION, APPRAISEMENT
AND EXEMPTION LAWS.

              (d) THE FOREGOING WAIVERS HAVE BEEN MADE WITH THE ADVICE OF
COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF.

              SECTION 18. INDEMNIFICATION. The Company agrees to indemnify the
Lender, from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may at any time be imposed on, incurred by or
asserted against the Lender in any way relating to or arising out of the
operation of the Company's business, any action taken by the Lender with respect
to any Account or Assigned Contract pursuant to this Agreement or any other
action taken by the Lender pursuant to the terms of this Agreement; provided,
however, that the Company shall not be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the Lender's gross
negligence or willful misconduct. Without limiting the generality of the
foregoing, the Company agrees to reimburse the Lender promptly upon demand for
any out-of-pocket expenses (including counsel fees of the counsel(s) of the
Lender's own choosing) incurred by the Lender in connection with the
preparation, execution, administration, or enforcement of, or legal advice with
respect to the rights or responsibilities of the parties under, this Agreement,
any suit or action brought by the Lender to enforce the terms of this Agreement,
any "lender liability" suit or claim brought against the Lender, and any claim
or suit brought against the Lender arising under any Federal or state
environmental statute, rule or regulation including, without limitation, the
Superfund Act, or the Federal Resource Conservation and Recovery Act of 1976, as
amended. Such out-of-pocket expenses (including counsel fees) shall be advanced
by the Company on the request of the Lender notwithstanding any claim or
assertion that the Lender is not entitled to indemnification hereunder upon
receipt of an undertaking by the Lender that the Lender will reimburse the
Company if it is actually and finally determined by a court of competent
jurisdiction that the Lender is not so entitled to indemnification. The
agreements in this Section shall survive the termination of this Agreement. The
Lender agrees to give the Company prompt notice of any suit or cause of action
brought against the Lender which is covered by this Section.

              SECTION 19. COUNTERPARTS. This Agreement may be executed in
several counterparts, each of which shall be an original and all of which, taken
together, shall constitute but one and the same instrument.

                               SUBSIDIARY GUARANTY


              This SUBSIDIARY GUARANTY (this "Guaranty") is made as of this ___
day of June, 1998, as follows:

                                    RECITALS

                      WHEREAS, Medirisk, Inc., a Delaware corporation (the
"Company") and NationsBank, N.A. (the "Lender") have entered into that certain
Amended and Restated Credit Agreement dated as of June __, 1998 (as the same may
be amended, supplemented or otherwise modified from time to time, the "Credit
Agreement") pursuant to which the Lender has agreed to make certain financial
accommodations to the Company in an aggregate principal amount not to exceed
$25,000,000 (the "Revolving Loans"), as evidenced by that certain Revolving Loan
Promissory Note issued by the Company to the order of the Lender (as such note
may be amended, modified, extended or renewed from time to time being
hereinafter referred to as the "Revolving Note"); and

                      WHEREAS, the entities listed on Exhibit A attached hereto,
and those additional entities that hereafter become parties hereto by executing
the form of Supplement attached hereto as Annex 1 (collectively, the
"Guarantors") are Subsidiaries of the Company; and

                      WHEREAS, the Company and the Guarantors are mutually
dependent on each other in the conduct of their respective businesses as an
integrated operation; and

                      WHEREAS, each of the Guarantors has determined that its
execution, delivery and performance of this Guaranty directly benefit, and are
within the corporate purposes and in the best interests of such Guarantor; and

                      WHEREAS, as a condition to the closing of the Credit
Agreement and the making of Revolving Loans thereunder, the Guarantors have
agreed to execute this Subsidiary Guaranty (the "Guaranty") guaranteeing the
payment and performance by the Subsidiaries of their Obligations (as defined in
the Loan Agreement) under the Revolving Note, the Credit Agreement and the other
Loan Documents executed by the Company (collectively, as such may be amended,
modified or extended from time to time, hereinafter referred to as the
"Guaranteed Agreements");

                      NOW, THEREFORE, in consideration of the above premises,
Ten Dollars ($10.00) in hand paid and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Guarantors hereby
guarantee to the Lender: (i) the full and prompt payment and performance of all
obligations of the Company to the Lender under the Guaranteed Agreements
(including, without limitation, any interest fees and other charges in respect
of the Guaranteed Agreements that would accrue but for the filing of a
bankruptcy action with respect to the Company, whether or not such claim is
allowed in such bankruptcy action); (ii) payment of any and all damages which
the Lender may suffer by reason of a breach of any obligation, covenant or
undertaking with respect to this Guaranty or any of the Guaranteed Agreements;
(iii) payment and performance of all of the obligations of any obligor to

<PAGE>   118

the Lender under this Guaranty and the Guaranteed Agreements, or as a result of
making the Revolving Loans; and (iv) any extensions, renewals or amendments of
any of the foregoing, however created, acquired, arising or evidenced, whether
direct or indirect, absolute or contingent, now or hereafter existing, or due or
to become due, including any interest thereon, plus reasonable attorneys' fees
and expenses if the obligations represented by this Guaranty are collected by
law, through an attorney-at-law, or under advice therefrom (all of the foregoing
obligations (i), (ii), (iii) and (iv) being hereinafter collectively referred to
as the "Obligations").

                      Each of the Guarantor and the Lender hereby further agree
that:

                      1.       Capitalized terms used herein and not otherwise
defined shall have the meanings ascribed thereto in the Credit Agreement.

                      2.       Regardless of whether any proposed guarantor or
any other Person or Persons is or are or shall become in any other way
responsible to the Lender for or in respect of the Obligations or any part
thereof, and regardless of whether or not any Person or Persons now or hereafter
responsible to the Lender for the Obligations or any part thereof, whether under
this Guaranty or otherwise, shall cease to be so liable, each Guarantor hereby
declares and agrees that this Guaranty shall be a several obligation, shall be a
continuing guaranty and shall be operative and binding until the earlier of such
time as (i) the Obligations shall have been paid or performed in full and the
Commitment shall have terminated or (ii) each Guarantor shall have satisfied all
of its obligations under this Guaranty.

                      3.       Upon the execution and delivery of this Guaranty
to the Lender, this Guaranty shall be deemed to be finally executed and
delivered by each Guarantor and shall not be subject to or affected by any
promise or condition affecting or limiting such Guarantor's liability, and no
statement, representation, agreement or promise on the part of the Lender or the
Company, or either of them, or any officer, employee or agent thereof, unless
contained herein, forms any part of this Guaranty or has induced the making
thereof or shall be deemed in any way to affect such Guarantor's liability
hereunder.

                      4.       No alteration or waiver of this Guaranty or of
any of its terms, provisions or conditions shall be binding upon the parties
against whom enforcement is sought unless made in writing and signed by an
authorized officer of such party.

                      5.       The Lender may from time to time, without 
exonerating or releasing any Guarantor in any way under this Guaranty, (i) take
such further or other security or securities for the Obligations or any part
thereof as the Lender may deem proper, (ii) release, discharge, abandon or
otherwise deal with or fail to deal with any guarantor of the Obligations or any
security or securities therefor or any part thereof now or hereafter held by the
Lender or (iii) amend, modify, extend, accelerate or waive in any manner any of
the provisions, terms, or conditions of the Guaranteed Agreements, all as the
Lender may consider expedient or appropriate in its sole discretion. Without
limiting the generality of the foregoing, or of Paragraph 6 hereof, it is
understood that the Lender may, without exonerating or releasing any Guarantor,
give up, modify or abstain from perfecting or taking advantage of any security
for the Obligations and accept or make any compositions or arrangements, and
realize upon


                                      -2-
<PAGE>   119

any security for the Obligations when, and in such manner, and with or without
notice, all as the Lender may deem expedient.

                      6.       Each Guarantor acknowledges and agrees that no 
change in the nature or terms of the Obligations or any of the Guaranteed
Agreements, or other agreements, instruments or contracts evidencing, related to
or attendant with the Obligations (including any novation), shall discharge all
or any part of the liabilities and obligations of such Guarantor pursuant to
this Guaranty; it being the purpose and intent of each Guarantor and the Lender
that the covenants, agreements and all liabilities and obligations of such
Guarantor hereunder are absolute, unconditional and irrevocable under any and
all circumstances. Without limiting the generality of the foregoing, each
Guarantor agrees that until each and every one of the covenants and agreements
of this Guaranty is fully performed, such Guarantor's undertakings hereunder
shall not be released, in whole or in part, by any action or thing which might,
but for this paragraph of this Guaranty, be deemed a legal or equitable
discharge of a surety or guarantor, or by reason of any waiver, omission of the
Lender or its failure to proceed promptly or otherwise, or by reason of any
action taken or omitted by the Lender whether or not such action or failure to
act varies or increases the risk of, or affects the rights or remedies of, such
Guarantor or by reason of any further dealings between the Company on the one
hand and the Lender on the other hand or any other guarantor or surety, and each
Guarantor hereby expressly waives and surrenders any defense to its liability
hereunder based upon, and shall be deemed to have consented to, any of the
foregoing acts, omissions, things, agreements or waivers.

                      7.       The Lender, without demand or notice of any kind
upon or to any Guarantor, at any time or from time to time when any amount shall
be due and payable hereunder by any Guarantor, if the Company shall not have
timely paid any of the Obligations after the lapse of any applicable cure
period, shall appropriate and apply to any portion of the Obligations hereby
guaranteed, and in such order of application as provided for in the Credit
Agreement, any property, balances, credit accounts or moneys of any Guarantor in
the possession of the Lender, or any affiliate of the Lender, or under its
control for any purpose.

                      8.       The creation or existence from time to time of
Obligations in excess of the amount committed to or outstanding on the date of
this Guaranty is hereby authorized, without notice to any Guarantor, and shall
in no way impair or affect this Guaranty or the rights of the Lender herein. It
is the intention of each Guarantor and the Lender that each Guarantor's
obligations hereunder shall be equal to, but not in excess of, the maximum
amount permitted by applicable Federal or state bankruptcy, insolvency,
fraudulent conveyance or transfer, or other Applicable Laws. To that end, but
only to the extent such obligations would otherwise be subject to avoidance
under the Applicable Laws if any Guarantor is not deemed to have received
valuable consideration, fair value or reasonably equivalent value for its
obligations under this Guaranty, such Guarantor's obligations under this
Guaranty shall be reduced to that amount which, after giving effect hereto,
would not render such Guarantor insolvent, or leave such Guarantor with
unreasonably small capital to conduct its business or cause such Guarantor to
have incurred debts (or intended to have incurred debts) beyond its ability to
pay such debts as they mature, at the time such obligations are deemed to have
been incurred under the Applicable Laws. As used herein, the terms "insolvent"


                                      -3-
<PAGE>   120

and "unreasonably small capital" shall likewise be determined in accordance with
the Applicable Laws.

                      9.       Upon the bankruptcy or winding up or other 
distribution of assets of the Company or of any surety or guarantor, or any of
the Guarantors, for any Obligations of the Company to the Lender, the Lender's
rights against all other Guarantors shall not be affected or impaired by the
Lender's omission to prove its claim, as appropriate, or to prove its full
claim, as appropriate, and the Lender may prove such claims as it sees fit, and
may refrain from proving any claim and, in its sole discretion, may value as it
sees fit or refrain from valuing any security held by it, without in any way
releasing, reducing or otherwise affecting the liability of any Guarantor
hereunder.

                      10.      Any amount received by the Lender from whatsoever
source and applied toward the payment of the Obligations shall be applied as
provided for in the Credit Agreement.

                      11.      Each Guarantor hereby expressly waives: (a)
notice of acceptance of this Guaranty; (b) notice of any liabilities,
indebtedness or Obligations to which it may apply, presentment, demand for
payment, protest, notice of dishonor or nonpayment of any liabilities; (c)
notice of intent to accelerate, notice of acceleration and notice of any suit or
the taking of other action by the Lender against the Company, any Guarantor or
any other person, any applicable statute of limitations and any other notice to
any party liable on any Loan Document (including Guarantor); (d) any claim,
right or remedy which such Guarantor may now have or hereafter acquire against
the Company that arises hereunder or from the performance by any other
guarantor, including, without limitation, any claim, remedy or right of
subrogation, reimbursement, exoneration, contribution, indemnification, or
participation in any claim, right or remedy of the Lender against the Company or
against any security which the Lender now has or hereafter acquires, whether or
not such claim, right or remedy arises in equity, under contract, by statute,
under common law or otherwise; and (e) the benefits of any provision of law
requiring that the Lender exhaust any right or remedy, or take any action,
against the Company, any other guarantor, any other person or property.

                      The Lender may at any time and from time to time (whether
before or after revocation or termination of this Guaranty) without notice to
the Guarantors (except as required by law), without incurring responsibility to
the Guarantors, without impairing, releasing or otherwise affecting the
obligations of the Guarantors, in whole or in part, and without the indorsement
or execution by any Guarantor of any additional consent, waiver or guaranty: (a)
change the manner, place or terms of payment, or change or extend the time of or
renew, or change any interest rate or alter any liability or Obligation or
installment thereof, or any security therefor; (b) loan additional monies or
extend additional credit to the Company, with or without security, thereby
creating new Obligations the payment or performance of which shall be guaranteed
hereunder, and the Guaranty herein made shall apply to the Obligations as so
changed, extended, surrendered, realized upon or otherwise altered; (c) sell,
exchange, release, surrender, realize upon or otherwise deal with in any manner
and in any order any property at any time pledged or mortgaged to secure the
Obligations and any offset there against; (d) exercise or refrain from
exercising any rights against the Company or others (including


                                      -4-
<PAGE>   121

any Guarantor) or act or refrain from acting in any other manner; (e) settle or
compromise any Obligation or any security therefor and subordinate the payment
of all or any part thereof to the payment of any Obligation of any other parties
primarily or secondarily liable on any of the Obligations; (f) release or
compromise any liability of the Guarantor hereunder or any liability or
obligation of any other parties primarily or secondarily liable on any of the
Obligations; or (g) apply any sums from any sources to any liability without
regard to any liabilities remaining unpaid.

                      12.      The Lender may, to the extent permitted under
the Credit Agreement, sell, assign or transfer all or any part of the
Obligations, and in such event each and every immediate and successive assignee,
transferee or holder of all or any of the Obligations, shall have the right to
enforce this Guaranty, by suit or otherwise, for the benefit of such assignee,
transferee or holder as fully as if such assignee, transferee or holder were
herein by name specifically given such rights, powers and benefits, but the
Lender shall have an unimpaired right, prior and superior to that of any such
assignee, transferee or holder, to enforce this Guaranty for the benefit of the
Lender, as to so much of the Obligations as the Lender shall have not sold,
assigned or transferred.

                      13.      No failure to exercise, and no delay in
exercising, any right hereunder or under any of the other Loan Documents held by
the Lender shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right preclude any other or future exercise thereof or the
exercise of any other right. The rights and remedies of the Lender provided
herein and in the other Loan Documents are cumulative and are in addition to,
and not exclusive of, any rights or remedies provided by law. The rights and
remedies of the Lender hereunder or under any other Loan Documents against any
party thereto are not conditional or contingent on any attempt by the Lender to
exercise any of its rights under any other Loan Document against such party or
against any other Person.

                      14.      This Guaranty shall be binding upon each 
Guarantor, its successors and assigns and inure to the benefit of the
successors and assigns of the Lender. No Guarantor shall assign its rights or
obligations under this Guaranty without the prior written consent of the
Lender.

                      15.      This is a guaranty of payment not of collection.
In the event the Lender makes a demand upon any Guarantor under this Guaranty,
such Guarantor shall be held and bound to the Lender directly as debtor in
respect of the payment of the amounts hereby guaranteed. All costs and expenses,
including reasonable attorneys' fees and expenses, incurred by the Lender in
obtaining performance of or collecting payments due under this Guaranty to the
extent permitted by the Credit Agreement, shall be deemed part of the
Obligations guaranteed hereby. Any notice or demand which the Lender may wish to
give shall be served upon the Guarantors in the fashion prescribed for notices
in Section 8.1 of the Credit Agreement, and the notice so sent shall be deemed
to be served as set forth in Section 8.1 of the Credit Agreement, to the address
of such Guarantor set forth on Exhibit A hereto or on any Supplement attached to
this Guaranty in accordance with Section 21 hereof.

                      16.      Each Guarantor expressly represents and 
acknowledges that any financial accommodations by the Lender to the Company,
including, without limitation, 


                                      -5-
<PAGE>   122

the extension of the Revolving Loans, are and will be of direct interest,
benefit and advantage to such Guarantor.

                      17.      Each Guarantor covenants and agrees that so long
as any amount is owing on account of the Revolving Loans, the Revolving Note or
otherwise pursuant to this Guaranty, such Guarantor shall permit, as provided in
the Credit Agreement with respect to the Company, representatives of the Lender
to visit and inspect properties of such Guarantor, inspect such Guarantor's
books and records and discuss with the principal officers of such Guarantor its
businesses, assets, liabilities, financial positions, results of operations and
business prospects.

                      18.      This Guaranty shall be construed in accordance
with and governed by the internal laws of the State of Georgia applicable to
contracts made and to be performed wholly within such state. This Guaranty,
together with all documents referred to herein, constitutes the entire agreement
between the Guarantors and the Lender with respect to the subject matter hereof
and may not be modified except by a writing executed by the Guarantors and the
Lender, and no waiver of any provision of this Guaranty, and no consent to any
departure by the Guarantors therefrom, shall in any event be effective unless
the same shall be in writing and signed by the Lender and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. This Guaranty shall be binding upon each Guarantor and
its successors and assigns, and shall inure to the benefit of the Lender and its
successors and assigns.

                      19.      In the event any term or condition contained
herein is inconsistent with the terms and conditions contained in the Credit
Agreement, the terms and conditions of the Credit Agreement shall control.

                      20.      Whenever possible each provision of this 
Guaranty shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Guaranty shall be prohibited or
invalid under such law, such provision shall be ineffective only to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision of this Guaranty.

                      21.      Pursuant to Section 4.9 of the Credit Agreement,
any new Subsidiary (whether by acquisition, creation or designation) of the
Company is required to enter into this Guaranty by executing and delivering to
the Lender an instrument in the form of Annex 1 attached hereto (a
"Supplement"). Upon the execution and delivery of a Supplement by such new
Subsidiary, such Subsidiary shall become a Guarantor hereunder with the same
force and effect as if originally named as a Guarantor herein. The execution and
delivery of any instrument adding an additional Guarantor as a party to this
Guaranty shall not require the consent of any other Guarantor hereunder. The
rights and obligations of each Guarantor hereunder shall remain in full force
and effect notwithstanding the addition of any new Guarantor hereunder.

              IN WITNESS WHEREOF, the Guarantors have caused this Guaranty to be
executed and sealed as of the date first above written.

as may be necessary or appropriate to evidence, protect and perfect the Security
Interest and shall cause its financial statements to reflect the Security
Interest.

                      SECTION 4.  COVENANTS REGARDING CONTRACTS.

                      (a)      Anything herein to the contrary notwithstanding, 
(i) each Guarantor shall remain liable under all Assigned Contracts (as
hereinafter defined) to which it is a party to the extent set forth therein to
perform its duties and obligations thereunder to the same extent as if this
Agreement had not been executed, (ii) the exercise by the Lender of any of its
rights hereunder shall not release any Guarantor from any of its duties or
obligations under any of the Assigned Contracts to which it is a party (except
to the extent that such exercise prevents such Guarantor from satisfying such
duties and obligations), and (iii) the Lender shall not have any duties,
obligations or liability under any of the Assigned Contracts or duties by reason
of this Agreement, nor shall the Lender be obligated to perform any of the
duties or obligations of any Guarantor thereunder, to make any payment, to make
any inquiry as to the nature or sufficiency of any payment received by any
Guarantor or the sufficiency of any performance by any party under any such


                                       -4-

contract or agreement, or to take any action to collect or enforce any claim for
payment assigned hereunder.

                      (b)      Each Guarantor shall at its expense:

                             (i) Perform and observe all the terms and
                      provisions of the Assigned Contracts to be performed or
                      observed by it, maintain the Assigned Contracts in full
                      force and effect to the extent of such Guarantor's normal
                      business practices, and enforce the Assigned Contracts in
                      accordance with their terms to the extent of such
                      Guarantor's normal business practices; and

                            (ii) Furnish to the Lender promptly upon receipt
                      thereof copies of all notices, requests and other
                      documents received by such Guarantor under or pursuant to
                      the Assigned Contracts, and from time to time (A) furnish
                      to the Lender such information and reports regarding the
                      Assigned Contracts as the Lender may reasonably request
                      and (B) upon request of the Lender, make to each other
                      party to the Assigned Contracts such demands and request
                      for information and reports or for action as such
                      Guarantor is entitled to make under the Assigned
                      Contracts.

                      (c)      Unless expressly set forth herein, all contracts
and contract rights of each Guarantor shall constitute Assigned Contracts and
shall constitute part of the Collateral.

                      SECTION 5.  COVENANTS REGARDING COLLATERAL GENERALLY.

                      (a)      Verification.  The Lender shall have the right at
any time and from time to time, in the name of the Lender or in the name of any
Guarantor, to verify the validity, amount or any other matter relating to any
Accounts by mail, telephone or otherwise.

                      (b)      Delivery of Instruments.  In the event any of 
the  Collateral becomes evidenced by a promissory note, trade acceptance or any
other instrument, the applicable Guarantor shall immediately thereafter deliver
such instrument to the Lender, appropriately endorsed to the Lender.

                      (c)      Defense of Title.  The Guarantors shall at all
times be the sole owners of each and every item of Collateral and shall defend,
at their sole cost and expense, their respective title in and to, and the
Security Interest of the Lender in, the Collateral against the claims and
demands of all Persons.

                      (d)      Maintenance of Collateral.  Each Guarantor shall 
maintain all physical property that constitutes Collateral in good and workable
condition, with reasonable allowance for wear and tear, and shall exercise
proper custody over all such property.

                      (e)      Insurance.  Each Guarantor shall maintain in
force with reputable insurers acceptable to the Lender such insurance with
respect to the Collateral as is required with respect to the Company under the
Credit Agreement. Each such insurance policy shall name the Lender as additional
named loss payee to the extent of the Guarantors' obligations hereunder and
shall provide for at least thirty (30) days' prior


                                       -5-

<PAGE>   133



written notice to the Lender of any expiration of, termination of or proposed
cancellation of such policy.

                      (f)      Location of Office.  Each Guarantor's chief
executive office, principal place of business and its books and records relating
to the Collateral shall continue to be kept at the address of such Guarantor set
forth above, and each Guarantor shall not change the location of such office and
place of business or such books and records without giving the Lender thirty
(30) days' prior written notice thereof.

                      (g)      Location of Collateral.  All Inventory, other
than Inventory in transit to any such location, and all Equipment shall at all
times be kept by the Guarantors at the locations set forth on Schedule 2(f), and
shall not, without the thirty (30) days' prior written notice to the Lender, be
removed therefrom except in connection with sales thereof in the ordinary course
of business.

                      (h)      Change of Name, Structure, Etc.  Without giving
the Lender thirty (30) days' prior written notice, none of the Guarantors shall
(i) change its name, identity or structure or (ii) conduct business under any
trade name or other fictitious name other than those set forth with respect to
such Guarantor on Schedule 2(a).

                      (i)      Records Relating to Collateral.  Each Guarantor
shall at all times keep complete and accurate records of Inventory, Equipment
and other Collateral.

                      (j)      Inspection.  The Lender (by any of its officers,
employees or agents) shall have the right, to the extent that the exercise of
such right shall be within the control of any Guarantor, at any time or times
during normal business hours: (i) to inspect the Collateral, all files relating
thereto and the premises upon which any of the Collateral is located, (ii) to
discuss such Guarantor's affairs and finances, insofar as the same are
reasonably related to the rights of the Lender hereunder with any Person, to
verify the amount, quantity, value and condition of, or any other matter
relating to, any of the Collateral and (iii) to review, audit and make extracts
from all records and files related to any of the Collateral.

                      (k)      Other Information.  Each Guarantor shall furnish
to the Lender such other information with respect to the Collateral as the
Lender may reasonably request from time to time.

                      (l)      Payments Directly to Lender.  Upon the
occurrence, and during the continuation, of an Event of Default, the Lender may
at any time and from time to time notify, or request any Guarantor to notify, in
writing or otherwise, any account debtor or other obligor with respect to any
one or more of the Accounts or Assigned Contracts to make payment to the Lender
or any agent or designee of the Lender directly, at such address as may be
specified by the Lender. If, notwithstanding the giving of any notice, any
account debtor or other such obligor shall make payment to any Guarantor, such
Guarantor shall hold all such payments it receives in trust for the Lender,
without commingling the same with other funds or property of or held by such
Guarantor, and shall promptly deliver the same to the Lender, or any such agent
or designee, immediately upon receipt by such Guarantor in the identical form
received, together with any necessary endorsements.

                      (m)      Sale of Collateral.  Except as permitted under
the terms of the Credit Agreement, none of the Guarantors shall sell, transfer,
convey or dispose of any Collateral

                                       -6-

<PAGE>   134



outside the ordinary course of its business; provided, however, that a Guarantor
may dispose of its Inventory in the ordinary course of its business so long as
no Default or Event of Default shall have occurred. The inclusion of "proceeds"
of the Collateral under the Security Interest shall not be deemed a consent by
the Lender to any other sale or other disposition of any part or all of the
Collateral.

                      (n)      Proceeds of Collateral.  Each Guarantor shall
account fully and faithfully for, and, following the occurrence and during the
continuation of an Event of Default, upon the Lender's request, promptly pay or
turn over to the Lender, proceeds in whatever form received in disposition in
any manner of any of the Collateral. To the extent practicable, each Guarantor
shall at all times keep the Collateral and proceeds thereof separate and
distinct from other property of such Guarantor and shall keep accurate and
complete records of the Collateral and proceeds thereof.

                      SECTION 6.  THE LENDER APPOINTED ATTORNEY-IN-FACT. Each
Guarantor hereby irrevocably appoints the Lender such Guarantor's
attorney-in-fact, with full authority in the place and stead of such Guarantor
and in the name of such Guarantor or otherwise, following the occurrence and
during the continuation of an Event of Default from time to time in the Lender's
discretion, to take any action and to execute any instrument or document which
the Lender may deem necessary or advisable to accomplish the purposes of this
Agreement and to exercise any rights and remedies the Lender may have under this
Agreement or Applicable Law, including, without limitation: (i) to obtain and
adjust insurance required to be maintained pursuant to Section 5(e) hereof; (ii)
to ask, demand, collect, sue for, recover, compromise, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Collateral, including, without limitation, any Account; (iii) to
receive, endorse and collect any drafts or other instruments, documents and
chattel paper, in connection with clause (i) or (ii) above; (iv) to sell or
assign any Account upon such terms, for such amount and at such time or times as
the Lender may deem advisable, to settle, adjust, compromise, extend or renew
any Account or to discharge and release any Account; and (v) to file any claims
or take any action or institute any proceedings which the Lender may deem
necessary or desirable for the collection of any of the Collateral or otherwise
to enforce the rights of the Lender with respect to any of the Collateral. The
power-of-attorney granted hereby shall be irrevocable and coupled with an
interest.

                      SECTION 7.  THE LENDER MAY PERFORM.  If any Guarantor
fails to perform any agreement contained herein, the Lender may, without notice
to any Guarantor, itself perform, or cause performance of, such agreement, and
the expenses of the Lender incurred in connection therewith shall be payable by
the Guarantors under Section 12 hereof.

                      SECTION 8.  THE LENDER'S DUTIES.  The powers conferred on
the Lender hereunder are solely to protect its interest in the Collateral and
shall not impose any duty upon the Lender to exercise any such powers. Except
for the safe custody of any Collateral in its possession and the accounting for
moneys actually received by it hereunder, the Lender shall have no duty as to
any Collateral. The Lender 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 the Lender accords its own property;
it being understood that the Lender shall be under no obligation to take any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral, but may do so at its option, and all reasonable
expenses incurred in

                                       -7-

<PAGE>   135



connection therewith shall be for the sole account of the Guarantors and shall
be added to the obligations of the Guarantors secured hereunder.

                      SECTION 9. REMEDIES. The Lender may take any or all of the
following actions upon the occurrence and during the continuation of an Event of
Default.

                      (a)      Inventory and Equipment.

                             (i) Entry. The Lender may enter upon any premises
                      on which Inventory or Equipment may be located and,
                      without resistance or interference by any Guarantor, take
                      physical possession of any or all thereof and maintain
                      such possession on such premises or move the same or any
                      part thereof to such other place or places as the Lender
                      shall choose, without being liable to any Guarantor on
                      account of any loss, damage or depreciation that may occur
                      as a result thereof, other than for actions that were not
                      taken in good faith.

                            (ii) Assembly. Each Guarantor shall, upon request of
                      and without charge to the Lender, assemble the Inventory
                      and Equipment and maintain or deliver it into the
                      possession of the Lender or any agent or representative of
                      the Lender at such place or places as the Lender may
                      reasonably designate.

                           (iii) Warehousing. The Lender may, at the expense of
                      the Guarantors, cause any of the Inventory and Equipment
                      to be placed in a public or field warehouse, and the
                      Lender shall not be liable to any Guarantor on account of
                      any loss, damage or depreciation that may occur as a
                      result thereof, other than for actions that were not taken
                      in good faith.

                      (b)      Use of Premises and Intellectual Property.  The
                      Lender may:

                             (i) without notice, demand or other process, and
                      without payment of any rent or any other charge enter any
                      of the Guarantors' premises and, without breach of the
                      peace, until the Lender completes the enforcement of its
                      rights in the Collateral, take possession of such premises
                      or place custodians in exclusive control thereof, remain
                      on such premises and use the same and any of the
                      Guarantors' equipment; and

                            (ii) in the exercise of the rights of the Lender
                      under this Agreement, without payment or compensation of
                      any kind, use any and all trademarks, trade styles, trade
                      names, patents, patent applications, licenses, franchises
                      and the like to the extent of the rights of any Guarantor
                      therein, and each Guarantor hereby grants a license to the
                      Lender for this purpose.

                      (c)      Lock Boxes.  The Lender may establish or cause to
be established one or more lock boxes or other arrangement for the deposit of
proceeds of Accounts, and, in such case, each Guarantor shall cause to be
forwarded to the Lender at the Lender's office set forth above, on a daily
basis, collection reports in form and substance satisfactory to the Lender.

                      (d)      Rights as a Secured Creditor.  The Lender may
exercise all of the rights and remedies of a secured party under the Uniform
Commercial Code and under any

                                       -8-

<PAGE>   136



other Applicable Law, including, without limitation, the right, without notice
except as specified below and with or without taking possession thereof, to sell
the Collateral or any part thereof in one or more parcels at public or private
sale at any location chosen by the Lender, for cash, on credit or for future
delivery, and at such price or prices and upon such other terms as the Lender
may deem commercially reasonable. Each Guarantor agrees that, to the extent
notice of sale shall be required by law, at least ten (10) days' notice to any
Guarantor of the time and place of any public sale or the time after which any
private sale is to be made shall constitute reasonable notification, but notice
given in any other reasonable manner or at any other reasonable time shall
constitute reasonable notification. The Lender shall not be obligated to make
any sale of Collateral regardless of notice of sale having been given. The
Lender may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefor, and such sale may, without further notice,
be made at the time and place to which it was so adjourned. The Lender may bid
all or any portion of the obligations of the Guarantors to the Lender secured
hereunder at any such sale.

                      (e)      Waiver of Marshaling.  Each Guarantor hereby
waives any right to require any marshaling of assets and any similar right.

                      (f)      Appointment of Receiver.  The Lender shall be
entitled to the appointment of a receiver, without notice of any kind whatsoever
and without regard to the adequacy of any security for all of the obligations of
the Guarantors to the Lender or the solvency of any party bound for its payment,
to take possession of all or any portion of the Collateral and the business
operations of any Guarantor and to exercise such power as the court shall confer
upon such receiver.

                      (g)      Accounts/Assigned Contracts.  The Lender shall 
have the exclusive right to assert, either directly or on behalf of any
Guarantor, any and all rights and claims any Guarantor may have under any
Accounts and any of the Assigned Contracts as the Lender may deem proper and to
receive and collect any and all Accounts and Assigned Contracts and any and all
rent, fees, damages, awards and other monies arising thereunder or resulting
therefrom and to apply the same on account of any of the obligations of the
Guarantors secured hereunder.

                      SECTION 10.  APPLICATION OF PROCEEDS.  All proceeds from 
each sale of, or other realization upon, all or any part of the Collateral
following an Event of Default, and all insurance proceeds payable by reason of
any damage or destruction of any of the Collateral, shall be applied or paid
over as follows:

                      (a)      First: to the payment of all costs and expenses
incurred in connection with such sale or other realization, including reasonable
attorneys' fees if the Lender endeavored to collect the Obligations by or
through an attorney at law;

                      (b)      Second: to the payment of the accrued interest
upon the Revolving Loans as provided in the Credit Agreement;

                      (c)      Third: to the payment of the outstanding 
principal of the Revolving Loans as provided in the Credit Agreement;

                      (d)      Fourth:  to the payment of the remaining 
outstanding Obligations as provided in the Credit Agreement; and


                                       -9-

<PAGE>   137



                      (e)      Fifth: the balance (if any) of such proceeds

shall be paid to the Guarantors or to whomsoever may be legally entitled
thereto.

Each Guarantor shall remain liable and shall pay, on demand, any deficiency
remaining in respect of the Obligations, together with interest thereon at a
rate per annum equal to the highest rate then payable under the Credit Agreement
on such Obligations, which interest shall constitute part of the Obligations.

                      SECTION 11.  RIGHTS CUMULATIVE.  The rights and remedies
of the Lender under this Agreement, the Credit Agreement and the other Loan
Documents shall be cumulative and not exclusive of any rights or remedies which
it would otherwise have, including, but not limited to, those rights afforded by
the Uniform Commercial Code and other Applicable Laws. In exercising its rights
and remedies the Lender may be selective, and no failure or delay by the Lender
in exercising any right shall operate as a waiver of it, nor shall any single or
partial exercise of any power or right preclude its other or further exercise or
the exercise of any other power or right.

                      SECTION 12.  EXPENSES.  The Guarantors, jointly and
severally, agree to pay, on demand, all reasonable out-of-pocket expenses
incurred by the Lender in connection with: (a) the negotiation, preparation,
execution, delivery and administration of this Agreement and any document or
instrument evidencing any of the Obligations whenever the same shall be executed
and delivered, including all appraisers' fees, search fees, recording fees,
intangibles and stamp taxes payable by the Lender with respect to the
Obligations and this Agreement and the Security Interest created hereby and the
fees and disbursements of counsel for the Lender, and of each local counsel
retained by the Lender; (b) the restructuring, refinancing or "workout" of the
transactions contemplated hereby and of the Obligations, and the preparation,
negotiation, execution and delivery of any waiver, amendment or consent by the
Lender relating to this Agreement or the Obligations, including, without
limitation, the fees, out-of-pocket expenses and other disbursements of counsel
to the Lender; (c) the collection or enforcement of the Obligations including
reasonable fees and disbursements of counsel to the Lender if such collection or
enforcement is done through or by an attorney; and (d) the exercise by the
Lender of any right or remedy granted to it under this Agreement whether or not
a Default or Event of Default has occurred, including, without limitation, the
expenses incurred by the Lender in connection with the collection of Accounts
directly from account debtors.

                      SECTION 13.  AMENDMENTS, ETC.  No amendment or waiver of
any provision of this Agreement nor consent to any departure by any Guarantor
here from shall in any event be effective unless the same shall be in writing
and signed by the parties hereto, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

                      SECTION 14.  NOTICES.  Unless otherwise provided herein, 
communications provided for hereunder shall be in writing and shall be mailed,
telecopied or delivered, to each party at the address specified for such party
on the signature pages hereof. All such notices and other communications shall
be effective upon satisfaction of the conditions set forth for similar notices
in Section 8.1 of the Credit Agreement.

                      SECTION 15.  CONTINUING SECURITY INTEREST.  This Agreement
shall create a continuing security interest in the Collateral and shall (i)
remain in full force and effect until indefeasible payment in full of the
Obligations, (ii) be binding upon each Guarantor, its successors and assigns and
(iii) inure the benefit of the Lender, and its successors and


                                      -10-

<PAGE>   138



assigns. Each Guarantor's successors and assigns shall include, without
limitation, a receiver, trustee or debtor-in-possession thereof or therefor.
Upon the indefeasible payment in full of all of the Obligations, the Security
Interest granted hereby shall terminate and all rights to the Collateral shall
revert to the applicable Guarantor. Upon any such termination, the Lender shall
at the Guarantors' expense, execute and deliver to such Guarantor such documents
as such Guarantor shall reasonably request to evidence such termination.

                      SECTION 16.  APPLICABLE LAW; SEVERABILITY.  THIS AGREEMENT
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
GEORGIA APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH
STATE (WITHOUT REGARD TO ANY CONFLICT OF LAWS PROVISIONS THAT INDICATE THE
APPLICABILITY OF ANY OTHER LAWS). Whenever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under Applicable Law, but if any provision of this Agreement shall be prohibited
by or invalid under Applicable Law, such provisions shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provisions or the remaining provisions of this Agreement.

                      SECTION 17.  LITIGATION/WAIVERS. (a) THE LENDER AND EACH
GUARANTOR ACKNOWLEDGE AND AGREE THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS
AGREEMENT OR THE RELATIONSHIP OF SUCH GUARANTOR AND THE LENDER ESTABLISHED
HEREBY AND THE DOCUMENTS AND INSTRUMENTS EVIDENCING THE OBLIGATIONS WOULD BE
BASED UPON DIFFICULT AND COMPLEX ISSUES. ACCORDINGLY, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, THE LENDER AND THE GUARANTORS EACH HEREBY WAIVE
THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY
KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY
OR AGAINST ANY GUARANTOR OR THE LENDER ARISING OUT OF THIS AGREEMENT, THE
OBLIGATIONS OR ANY OTHER DOCUMENT EXECUTED AND DELIVERED IN CONNECTION HEREWITH
OR THEREWITH OR IN CONNECTION WITH THE COLLATERAL OR THE SECURITY INTEREST
THEREIN OR BY REASON OF ANY OTHER CAUSE OR DISPUTE WHATSOEVER BETWEEN ANY
GUARANTOR AND THE LENDER OF ANY KIND OR NATURE.

                      (b)      EACH GUARANTOR AND THE LENDER HEREBY AGREE

JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN SUCH GUARANTOR
AND THE LENDER, PERTAINING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE
OBLIGATIONS OR TO ANY MATTER ARISING THEREFROM, THE COLLATERAL OR THE SECURITY

                      (c)      FURTHER, EACH GUARANTOR WAIVES (I) ANY NOTICE
PRIOR TO THE TAKING POSSESSION OR CONTROL OF THE COLLATERAL OR ANY POSTING OF
ANY BOND OR SECURITY WHICH MIGHT BE REQUIRED BY ANY COURT PRIOR TO ALLOWING THE
LENDER TO EXERCISE ANY OF THE LENDER'S REMEDIES SET FORTH HEREIN, INCLUDING THE
ISSUANCE OF AN IMMEDIATE WRIT OF POSSESSION AND (II) THE BENEFIT OF ALL
VALUATION, APPRAISEMENT AND EXEMPTION LAWS.

                      (d)      THE FOREGOING WAIVERS HAVE BEEN MADE WITH THE
ADVICE OF COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL
CONSEQUENCES THEREOF.

                      SECTION 18.       INDEMNIFICATION.  Each Guarantor agrees
to indemnify the Lender, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may at any time be imposed
on, incurred by or asserted against the Lender in any way relating to or arising
out of the operation of such Guarantor's business, any action taken by the
Lender with respect to any Account or Assigned Contract pursuant to this
Agreement or any other action taken by the Lender pursuant to the terms of this
Agreement; provided, however, that such Guarantor shall not be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from the
Lender's gross negligence or willful misconduct. Without limiting the generality
of the foregoing, each Guarantor agrees to reimburse the Lender promptly upon
demand for any out-of-pocket expenses (including counsel fees of the counsel(s)
of the Lender's own choosing) incurred by the Lender in connection with the
preparation, execution, administration, or enforcement of, or legal advice with
respect to the rights or responsibilities of the parties under, this Agreement,
any suit or action brought by the Lender to enforce the terms of this Agreement,
any "lender liability" suit or claim brought against the Lender, and any claim
or suit brought against the Lender arising under any Federal or state
environmental statute, rule or regulation including, without limitation, the
Superfund Act, or the Federal Resource Conservation and Recovery Act of 1976, as
amended. Such out-of-pocket expenses (including counsel fees) shall be advanced
by such Guarantor on the request of the Lender notwithstanding any claim or
assertion that the Lender is not entitled to indemnification hereunder upon
receipt of an undertaking by the Lender that the Lender will reimburse such
Guarantor if it is actually and finally determined by a court of competent
jurisdiction that the Lender is not so entitled to indemnification. The
agreements in this Section shall survive the termination of this Agreement. The
Lender agrees to give the Guarantors prompt notice of any suit or cause of
action brought against the Lender which is covered by this Section.

                      SECTION 19.  COUNTERPARTS.  This Agreement may be executed
in several counterparts, each of which shall be an original and all of which,
taken together, shall constitute but one and the same instrument.

                      SECTION 20.  DEFINITIONS. (a) For the purposes of this

security title to all of the Collateral (as defined in the Subsidiary Security
Agreement) of the New Guarantor and all additions thereto and replacements
thereof, and all other property of the New Guarantor whether now owned or
hereafter created, acquired or reacquired. The Schedules attached hereto
supplement the Schedules to the Subsidiary Security Agreement, and shall be
deemed a part thereof for all purposes of the Subsidiary Security Agreement.
Each reference to a 'Guarantor' in the Subsidiary Security Agreement shall be
deemed to include the New Guarantor. The Subsidiary Security Agreement is
incorporated herein by reference.

              SECTION 2. The New Guarantor represents and warrants to the Lender
that this Supplement has been duly executed and delivered by the New Guarantor
and constitutes its legal, valid and binding obligation, enforceable against it
in accordance with its terms, except as enforceability thereof may be limited by
bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other
similar laws affecting creditors' rights generally and general principles of
equity (regardless of whether such enforceability is considered in a proceeding
at law or in equity).

              SECTION 3. This Supplement may be executed in multiple
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

              SECTION 4. Except as expressly supplemented hereby, the Subsidiary
Security Agreement shall remain in full force and effect.

              SECTION 5. This Supplement shall be construed and interpreted in
accordance with the internal laws of the State of Georgia applicable to
agreements to be made and performed wholly within the State of Georgia.
