                          Physicians' Specialty Corp.
           Notes to the Consolidated Financial Statements (Unaudited)
                                 March 31, 1997

Note 1. ORGANIZATION

     Physicians' Specialty Corp. (the "Company") was organized in July 1996 to
provide comprehensive physician practice management services to physician
practices and health care providers specializing in the treatment and
management of diseases and disorders of the ear, nose, throat, head and neck
("ENT").  The Company commenced its business activities upon consummation of
the reorganization, as described in Note 3, on March 26, 1997. The Company
provides financial and administrative management, enhancement of clinical
operations, network development and payor contracting services, including the
negotiation and administration of capitated arrangements.


Note 2. BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries and have been prepared in accordance with
generally accepted accounting principles for interim financial reporting and in
accordance with Rule 10-01 of Regulation S-X. Accordingly, they do not include
all of the information and notes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, the
accompanying unaudited consolidated financial statements contain all
adjustments (consisting of normal recurring items) necessary for a fair
presentation of the results for the interim periods presented. These financial
statements and footnote disclosures should be read in conjunction with the
audited financial statements and unaudited pro-forma combined financial
statements and the notes thereto included in the Company's prospectus dated
March 20, 1997.

     The Company's  consolidated operations for the quarter ended March 31,
1997 consisted of only five business days in light of the closing of the
Company's initial public offering ("IPO") and practice asset acquisitions on
March 26, 1997. Because the Company was incorporated in July 1996 there is no
comparative information available at or for the period ended March 31, 1996.

Note 3. REORGANIZATION

     Concurrently with the closing of the IPO, the Company acquired
substantially all of the assets of Atlanta Ear, Nose & Throat Associates, P.C.,
three additional ENT  practices in the metropolitan Atlanta area (collectively,
"Atlanta ENT"), and one ENT practice in Birmingham, Alabama ("Birmingham ENT").
In addition the Company purchased the common stock of three corporations (the
"ENT Networks") which at March 31, 1997 held, managed and administered
capitated ENT managed care contracts covering an aggregate of 399,096 
enrollees of health maintenance organizations ("HMOs") sponsored by United
Healthcare of Georgia ("United Healthcare"), Aetna Health Plans of Georgia,
("Aetna") and Cigna HealthCare of Georgia ("Cigna").

     In connection with the acquisitions, the Company entered into management
services agreements with the physician practices providing for the
comprehensive management of the practices by the Company, while enabling the
practices to retain



                                      6


<PAGE>   7

authority over the provision of medical care. The management services agreement
with Atlanta ENT provides for the assignment to the Company by Atlanta ENT of
all or substantially all of its non-governmental accounts receivable and all of
its rights and interest in the proceeds of its governmental accounts receivable
and grants to the Company the right to collect and retain the proceeds of the
accounts receivable for the Company's account to be applied in accordance with
the agreement. The Company is responsible for the payment of operating and
non-operating expenses of Atlanta ENT (excluding compensation to physicians and
physician assistants) and is responsible to pay for all such expenses directly
out of the proceeds of the accounts receivable assigned to the Company by
Atlanta ENT. In addition, the Company retains a management fee equal to 12.5%
of all revenues (after adjustment for contractual allowances) generated by or
on behalf of physicians practicing at Atlanta ENT, subject to specified maximum
annual amounts, as payment for the Company's services and non-allocable costs
incurred by the Company attributable to the provision of management services
under the management services agreement. In addition, the Company is entitled
to incentive compensation under the management services agreement upon the
receipt by the Company of specified maximum annual management fees. The
remaining revenues are remitted to Atlanta ENT to pay physician and physician
assistant compensation and benefits.

     Simultaneous with the acquisition of substantially all of the assets of
Birmingham ENT, the physicians at Birmingham ENT entered into employment
agreements with PSC Alabama, a wholly-owned subsidiary of the Company ("PSC
Alabama"). The  assignment of accounts receivable, realization of revenues, and
allocation of costs and expenses are governed by a management services
agreement between PSC Alabama and the Company which is substantially similar to
the management services agreement between Atlanta ENT and the Company.

     At March 31, 1997 the Company was affiliated with 23 physicians, 1
dentist, and 26 allied healthcare professionals operating 19 clinical
facilities


NOTE 4.  INITIAL PUBLIC  OFFERING
     On March 26, 1997, the Company completed its IPO of 2,200,000 shares of
its common stock. The net proceeds of the offering were approximately
$14,981,000,  and were and will be used for repayment of indebtedness of the
acquired practices, repayment of indebtedness of the Company, payment of a
consulting fee, and working capital requirements.

NOTE 5. SUBSEQUENT EVENTS

        In April 1997 the Company announced that it received notification that
Aetna is modifying its delivery system of physician specialty services in the
Atlanta market. As part of this modification, Aetna is terminating its
capitated managed care contracts with each physician specialty group including
the Company effective June 30, 1997. The Company's affiliated physicians will
be able to  continue to provide services to Aetna enrollees subsequent to June
30, 1997 upon execution of new physician provider agreements. The Company
anticipates that these new provider agreements will reimburse physicians on a
modified fee-for-service basis. As described in Note 3, the Company's three
capitated managed care contracts covered an aggregate of


                                      7


<PAGE>   8

399,096 enrollees at March 31, 1997 (of which 50,331 were enrollees covered by
the Aetna contract).  The Company does not believe the Aetna contract
termination will have a material adverse effect on the Company's business,
financial condition or results of operations.

     On April 30, 1997, the Company closed on a five year $20.0 million
senior working capital and acquisition credit facility provided by NationsBank,
N.A. (South). Advances under the credit facility will bear interest, at the
Company's option, at either a prime-based rate or a LIBOR-based rate with
interest only payments required during the first three years of the credit
agreement. Thereafter, in years four and five of the agreement, the term loan
commitment will be reduced to $13,333,333 and $6,666,666 respectively.
Borrowings under the credit facility are secured by the capital stock of the
Company's subsidiaries and the Company's accounts receivable, and will be
secured by acquisition documents in connection with physician practice equity
or assets acquired.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


GENERAL

     The Company is a physician practice management company organized in July
1996 that provides management services to physician practices and health care
providers specializing in the treatment and management of diseases and
disorders of the ear, nose, throat, head and neck . The Company commenced
business activities upon consummation of the reorganization, as described in
Note 3 of the Notes to Consolidated Financial Statements, on March 26, 1997.
Prior to this date, the Company conducted only limited activities primarily
consisting of acquiring computer hardware and negotiating the agreements
relating to the reorganization and the initial public offering.  The Company
provides financial and administrative management, enhancement of clinical
operations, network development and payor contracting services, including the
negotiation and administration of capitated arrangements.

     The Company's unaudited consolidated results for the quarter ended March
31, 1997 consisted of only five business days of operations following the
consummation of the acquisition of the assets of the acquired practices which
included Atlanta ENT and Birmingham ENT, and the acquisition of the common
stock of the ENT Networks (the "Reorganization"). Each of the acquisitions was
accounted for as a combination of promoter interest at historical costs, and
was based upon the historical statements of each entity. The accounts
receivable were generally purchased at the net realizable value.

     The Company's relationships with its affiliated physicians are set
forth in various asset acquisition agreements, management services agreements,
and physician employment agreements. The management services agreements, which
have a term of 40 years, delineate the responsibilities and obligations of the
physician practices and the Company. In connection with the Reorganization, the
Company entered into management services agreements with Atlanta ENT and with
PSC Alabama (which directly employed the physicians of Birmingham ENT. These
management services agreements provide for the affiliated practices to assign
to the Company all of its non-governmental accounts receivable and all of its
right and interest in the proceeds of its governmental accounts receivable and
grant to the Company the right to collect and retain the proceeds of the
accounts receivable for the Company's account to be applied in accordance with
the agreement.

     The Company is responsible for the payment of operating expenses of the
affiliated physician practices, including salaries and benefits of non-medical
employees of the practices, lease obligations for office space and equipment,
medical and office supplies,



                                      9


<PAGE>   10

and the non-operating expenses of the affiliated physician practices, including
depreciation, amortization and interest. The Company pays for all such expenses
directly out of the proceeds of the accounts receivable assigned to the Company
by the affiliated physician practices. In addition, under the management
services agreements with Atlanta ENT and PSC Alabama, the Company retains as
a part of its management fee, a stipulated percentage (12.5%) of all revenues
(after adjustment for contractual allowances) generated by or on behalf of
physicians practicing at such practice, as payment for the Company's management
services and non-allocable costs incurred by the Company attributable to the
provision of management services. Contractual allowances are the difference
between the amounts customarily charged by physicians practicing at such
practice and the amounts received pursuant to negotiated fee schedules from
payors under indemnity arrangements, managed care contracts and preferred
provider arrangements.


     Under the management services agreements with Atlanta ENT and PSC Alabama,
the Company retains on an annual basis, 12.5% of affiliated physician
practice revenue until such revenue equals 150% of such practice's annual
revenue in the year prior to its affiliation with the Company (the "Threshold
Amount"). In the event the affiliated practice's revenue exceeds the Threshold
Amount in any fiscal year, the Company is entitled to incentive compensation
(in lieu of the 12.5% amount) for the remainder of such fiscal year in amounts
ranging from 20% to 25% of the affiliated practice's income (net practice
revenues less practice expenses), prior to the payment of physician
compensation and benefits. The Company will remit the remaining revenues to the
affiliated practice to pay compensation and benefits to physicians pursuant to
employment agreements between the practice and each physician, and to physician
assistants. The percentage components of the management fee to be retained by
the Company under future management services agreements will be determined
based upon negotiations between the Company and future affiliating practices
and may vary significantly in the future.

     At March 31, 1997 the ENT Networks held capitated managed care contracts
with Cigna, Aetna, and United Healthcare which require the ENT Networks to
contract for the provision of substantially all of the ENT medical and surgical
services required by the enrollees of these HMOs in the Atlanta market. In
exchange, the ENT Networks receive pre-determined amounts per patient per
month. The ENT Networks have contracted with participating physicians,
including those at Atlanta ENT, to provide substantially all of such medical
services in exchange for compensation on a discounted fee-for-service basis.
Such contracts pass much of the financial risk of providing care, such as
over-utilization from the payor to the provider.

     In April 1997 the Company announced that it received notification that
Aetna is modifying its delivery system of physician specialty services in the
Atlanta market. As part of this modification, Aetna is terminating its
capitated managed care contracts with each physician specialty group including
the Company effective June 30, 1997. The Company's affiliated physicians will
be able to continue to provide services to Aetna enrollees



                                      10


<PAGE>   11

subsequent to June 30, 1997 upon execution of new physician provider
agreements. The Company anticipates that these new provider agreements will
reimburse physicians on a modified fee-for-service basis. The Company's three
capitated managed care contracts covered an aggregate of 399,096 enrollees at
March 31, 1997 (of which 50,331 were enrollees covered by the Aetna contract).
Excluding the Aetna enrollees, the number of enrollees covered under the
remaining contracts with United Healthcare and Cigna increased at March 31,
1997 by 9.5% from the number of enrollees at December 31, 1996. As a result of
the foregoing, the Company does not believe the Aetna contract termination will
have a material adverse effect on the Company's business, financial condition
or results of operation.

     The Company's revenues are derived (i) under the management services
agreement with Atlanta ENT, (ii) from patient service revenues generated by the
Company's wholly-owned subsidiary, PSC Alabama, which directly employs the
Birmingham ENT physicians, and (iii) under capitated managed care contracts
held by the ENT Networks, which are wholly-owned subsidiaries of the Company.

     Except for the descriptions of historical facts contained herein,
statements concerning future results, performance or expectations are
forward-looking statements. Actual results, performance or developments could
differ materially from those expressed or implied by such forward-looking
statements as a result of known and unknown risks, uncertainties and other
factors including those described from time to time in the Company's filings
with the Securities and Exchange Commission, under "Risk Factors" and
elsewhere, including the Company's limited operating history and risks relating
to acquisitions and managing growth; dependence on affiliated physicians;
dependence on managed care organizations and risks associated with capitated
arrangements, including potential reductions in reimbursement; competition;
regulatory risks; risks relating to credit facility and substantial leverage;
and other risks.



RESULTS OF OPERATIONS

     Net revenues were $238,951 for the quarter ended March 31, 1997,
consisting of $156,742 of management fees, $26,361 of patient service revenue,
and $55,848 of capitated revenue.

     Total operating expenses were $219,074 for the quarter ended March 31,
1997  consisting largely of provider claims, wages and benefits and
administrative expenses.

     Interest income of $13,193 was earned for the quarter ended March 31, 1997
as a result of the investment of the IPO proceeds for a five day period.

     The provision for income taxes was established at an estimated 39%
effective tax rate.

LIQUIDITY AND CAPITAL RESOURCES


     Net cash provided by operating activities for the three month period ended
March 31, 1997 was $432,063, while cash used in investing activities was
$13,256. Cash provided by financing activities was  $15,432,000 for the three
month period primarily due to the net proceeds received from the Company's
initial public offering of 2.2 million shares of common stock

     As of March 31, 1997 the Company had working capital of $14,913,544
including cash and cash equivalents of $15,986,975.

     During April, 1997, the Company repaid outstanding indebtedness in the
aggregate amount of $1,764,843 incurred in conjunction with the Reorganization
and assumption of certain liabilities of certain of the physician practices,
the assets of which were acquired in the Reorganization.

     On April 30, 1997 the Company closed on a five year $20.0 million
senior working capital and acquisition credit facility provided by NationsBank,
N.A. (South). Advances under the credit facility will be governed by a
borrowing base formula and will bear interest, at the Company's option, at
either a prime-based rate or a LIBOR-based rate with  interest only payments
required during the first three years of the agreement. Thereafter, in years
four and five of the agreement, the term loan commitment is reduced to
$13,333,333 and $6,666,666, respectively. The bank credit facility contains
affirmative and negative covenants, which among other things require the
Company to maintain certain financial ratios including the ratio of funded debt
(as defined in the credit agreement) to earnings before interest, taxes,
depreciation and amortization (as defined in the credit agreement); the ratio
of funded debt to net worth; the ratio of current assets to current
liabilities; and debt service and interst coverage ratios, and sets certain
restrictions on investments, mergers and sale of assets. Borrowings under the
credit facility are secured by the capital stock of the Company's subsidiaries
and the Company's accounts receivable, and will be secured by acquisition
documents in connection with physician practice equity or assets acquired.

     The Company is currently in discussions related to the acquisition of the
assets or the equity of additional  ENT and complimentary physician practices,
although it has not executed definitive agreements with respect to any specific
acquisition. The Company intends to fund future acquisitions with cash or cash
equivalents, borrowings under the bank credit facility, issuance of long-term
or short-term indebtedness and/or the issuance of additional equity securities.
There can be no assurance as to the terms of any such acquisitions or as to the
Company's ability to complete future acquisitions.

SECTION 2.2 RATES AND PAYMENT OF INTEREST ON LOANS.

       (a) Rates. The Borrower promises to pay to the Lender interest on the
unpaid principal amount of each Loan for the period from and including the date
of the making of such Loan to but excluding the date such Loan shall be paid in
full, at the following per annum rates:

           (i)  during such periods as such Loan is a Base Rate Loan, at the

       and

           (ii) during such periods as such Loan is a LIBOR Loan, at LIBOR

date thereof to but excluding the date the same is paid in full.

       (b) Payment. Accrued interest on each Loan shall be payable (i) in the
case of a Base Rate Loan, on the last day of each calendar month, (ii) in the
case of a LIBOR Loan, on the last day of each Interest Period therefor and (iii)

outstanding Term Loans shall exceed the lesser of (A) the Maximum Acquisition
Loan Amount and (B) the Term Loan Commitment or (iii) the aggregate amount of

in the case of clause (iii) above, prepay the Loans in an amount sufficient to

Period therefor, the Borrower shall pay all amounts due under Section 4.4.

Borrower may on any Business Day, with respect to any LIBOR Loan, elect to
maintain such LIBOR Loan or any portion thereof as a LIBOR Loan by selecting a
new Interest Period for such LIBOR Loan. Each new Interest Period selected under
this Section shall commence on the last day of the immediately preceding
Interest Period. Each selection of a new Interest Period shall be made by the
Borrower giving to the Lender a Notice of Continuation not later than 12:00 noon
on the third Business Day prior to the date of any such Continuation. Such
notice by the Borrower of a Continuation shall be by telephone or telecopy,
confirmed immediately in writing if by telephone, in the form of a Notice of

into a Base Rate Loan notwithstanding failure of the Borrower to comply with
Section 2.7.

SECTION 2.7  CONVERSION.

       So long as no Default or Event of Default shall have occurred, the
Borrower may on any Business Day, upon the Borrower's giving of a Notice of
Conversion to the Lender, Convert all or a portion of a Loan of one Type into a
Loan of another Type. Any Conversion of a LIBOR Loan into a Base Rate Loan shall
be made on, and only on, the last day of an Interest Period for such LIBOR Loan
and, upon Conversion of a Base Rate Loan into a LIBOR Loan, the Borrower shall
pay accrued interest to the date of Conversion on the principal amount so
Converted. Each such Notice of Conversion shall be given not later than 12:00
noon on the Business Day prior to the date of any proposed Conversion into Base
Rate Loans and on the third Business Day prior to the date of any proposed
Conversion into LIBOR Loans. Subject to the restrictions specified above, each

amount of the Commitment at any time and from time to time without penalty or
premium upon not less than three Business Days prior written notice to the
Lender of each such termination or reduction, which notice shall specify the
effective date thereof, whether such reduction is a reduction of the Revolving
Loan Commitment or the Term Loan Commitment and the amount of any such reduction
and shall be irrevocable once given and effective only upon receipt by the
Lender. The Commitment, once terminated or reduced, may not be increased or

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 of the parties hereto
that the Borrower not pay and the Lender not receive, directly or indirectly, in
any manner whatsoever, interest in excess of that which may be lawfully paid by
the Borrower under Applicable Law.

SECTION 3.6  AGREEMENT REGARDING INTEREST AND CHARGES.

Notwithstanding the foregoing, the parties hereto further agree and stipulate
that all facility fees, underwriting fees, default charges, late charges,
funding or "breakage" charges, increased cost charges, attorneys' fees and

damages incurred by the Lender, are charges made to compensate the Lender for
underwriting or administrative services and costs or losses performed or
incurred, and to be performed or incurred, by the Lender in connection with this
Agreement and shall under no circumstances be deemed to be charges for the use
of money pursuant to Official Code of Georgia Annotated Sections 7-4-2 and
7-4-18. All charges other than charges for the use of money shall be fully
earned and nonrefundable when due.

       The Lender will account to the Borrower with a statement of Loans,
accrued interest and Fees, charges and payments made pursuant to this Agreement
and the other Loan Documents, and such account rendered by the Lender shall be

statement of accounts shall not relieve or discharge the Borrower from any of
its obligations hereunder.

<PAGE>   27

SECTION 3.8   TAXES.

       (a)    Taxes Generally. All payments by the Borrower of principal of, and
interest on, the Loans and all other Obligations shall be made free and clear of
and without deduction for any present or future excise, stamp or other taxes,
fees, duties, levies, imposts, charges, deductions, withholdings or other
charges of any nature whatsoever imposed by any taxing authority, but excluding
(i) franchise taxes, (ii) any taxes (other than withholding taxes) that would
not be imposed but for a connection between the Lender and the jurisdiction
imposing such taxes (other than a connection arising solely by virtue of the
activities of the Lender pursuant to or in respect of this Agreement or any
other Loan Document), (iii) any withholding taxes payable with respect to
payments hereunder or under any other Loan Document under Applicable Law in
effect on the Agreement Date, and (iv) any taxes imposed on or measured by the
Lender's assets, net income, receipts or branch profits (such non-excluded items
being collectively called "Taxes"). If any withholding or deduction from any
payment to be made by the Borrower hereunder is required in respect of any Taxes
pursuant to any Applicable Law, then the Borrower will:

              (i)   pay directly to the relevant Governmental Authority the full
       amount required to be so withheld or deducted;

              (ii)  promptly forward to the Lender an official receipt or other
       documentation satisfactory to the Lender evidencing such payment to such
       Governmental Authority; and

              (iii) pay to the Lender such additional amount or amounts as is
       necessary to ensure that the net amount actually received by the Lender
       will equal the full amount that the Lender would have received had no
       such withholding or deduction been required.

       (b)    Tax Indemnification. If the Borrower fails to pay any Taxes when
due to the appropriate Governmental Authority or fails to remit to the Lender
the required receipts or other required documentary evidence, the Borrower shall
indemnify the Lender for any incremental Taxes, interest or penalties that may
become payable by the Lender as a result of any such failure.

                       ARTICLE IV. YIELD PROTECTION, ETC.

SECTION 4.1   ADDITIONAL COSTS; CAPITAL ADEQUACY.

       (a)    Additional Costs. The Borrower shall promptly pay to the Lender
from time to time such amounts as the Lender may reasonably determine to be
necessary to compensate the Lender for any costs incurred by the Lender that
it determines are attributable to its making or maintaining of any LIBOR Loans
or its obligation to make any LIBOR Loans hereunder, any reduction in any amount
receivable by the Lender under this Agreement or any of the other Loan Documents
in respect of any of such Loans or such obligations or the maintenance by the
Lender of capital in respect of its Loans or its Commitment (such increases in
costs and reductions in amounts receivable being herein called "Additional
Costs"), resulting from any Regulatory Change that: (i) changes the basis of
taxation of any amounts payable to the Lender under this Agreement or any of the
other Loan Documents in respect of any of such Loans or its Commitment (other
than taxes imposed on or measured by the overall net income of the Lender or of
its Principal 



                                      -27-
<PAGE>   28

Office for any of such Loans by the jurisdiction in which the Lender has such
Office); or (ii) imposes or modifies any reserve, special deposit or similar
requirements (including, without limitation, any reserves required to be
maintained against (i) "Eurocurrency liabilities" as specified in Regulation D
of the Board of Governors of the Federal Reserve System or (ii) any other
category of liabilities which includes deposits by reference to which the
interest rate on LIBOR Loans is determined or (iii) any category of extensions
of credit or other assets which includes loans by an office of the Lender
outside of the United States of America to residents of the United States of
America)) relating to any extensions of credit or other assets of, or any
deposits with or other liabilities of, the Lender, or any commitment of the
Lender (including, without limitation, the Commitment); or (iii) has or would
have the effect of reducing the rate of return on capital of the Lender to a
level below that which the Lender could have achieved but for such Regulatory
Change (taking into consideration the Lender's policies with respect to capital
adequacy).

       (b) Lender's Suspension of LIBOR Loans. Without limiting the effect of
the provisions of the immediately preceding subsection (a), if by reason of any
Regulatory Change, the Lender either (i) incurs Additional Costs based on or
measured by the excess above a specified level of the amount of a category of
deposits or other liabilities of the Lender that includes deposits by reference
to which the interest rate on LIBOR Loans is determined as provided in this
Agreement or a category of extensions of credit or other assets of the Lender
that includes LIBOR Loans or (ii) becomes subject to restrictions on the amount
of such a category of liabilities or assets that it may hold, then, if the
Lender so elects by notice to the Borrower, the obligation of the Lender to make
or Continue, or to Convert Base Rate Loans into, LIBOR Loans hereunder shall be
suspended until such Regulatory Change ceases to be in effect (in which case the
provisions of Section 4.5. shall apply).

       (c) Notification and Determination of Additional Costs. The Lender agrees
to notify the Borrower of any event occurring after the Agreement Date entitling
the Lender to compensation under any of the preceding subsections of this
Section as promptly as practicable; provided, however, that the failure of the
Lender to give such notice shall not release the Borrower from any of its
obligations hereunder. The Lender agrees to furnish to the Borrower a
certificate setting forth in reasonable detail the basis and amount of each
request by the Lender for compensation under this Section. Determinations by the
Lender of the effect of any Regulatory Change shall be conclusive, provided that
such determinations are made on a reasonable basis and in good faith. The Lender
shall only be entitled to compensation under this Section for events occurring
during the 180 day period ending on the date the Borrower has actual knowledge
of the occurrence of any such event entitling the Lender to compensation under
this Section.

SECTION 4.2   SUSPENSION OF LIBOR LOANS.

       Anything herein to the contrary notwithstanding, if, on or prior to the
determination of LIBOR for any Interest Period:

              (a) the Lender reasonably determines (which determination shall be
       conclusive) that quotations of interest rates for the relevant deposits
       referred to in the definition of LIBOR are not being provided in the
       relevant amounts or for the relevant maturities for



                                      -28-
<PAGE>   29

       purposes of determining rates of interest for LIBOR Loans as provided
       herein or is otherwise unable to determine LIBOR, or

              (b) the Lender reasonably determines (which determination shall be
       conclusive) that the relevant rates of interest referred to in the
       definition of LIBOR upon the basis of which the rate of interest for
       LIBOR Loans for such Interest Period is to be determined are not likely
       adequately to cover the cost to the Lender of making or maintaining LIBOR
       Loans for such Interest Period;

then the Lender shall give the Borrower prompt notice thereof and, so long as
such condition remains in effect, the Lender shall be under no obligation to,
and shall not, make additional LIBOR Loans, Continue LIBOR Loans or Convert
Loans into LIBOR Loans and the Borrower shall, on the last day of each current
Interest Period for each outstanding LIBOR Loan, either prepay such Loan or
Convert such Loan into a Base Rate Loan.

SECTION 4.3   ILLEGALITY.

       Notwithstanding any other provision of this Agreement, if it becomes
unlawful for the Lender to honor its obligation to make or maintain LIBOR Loans
hereunder, then the Lender shall promptly notify the Borrower thereof and the
Lender's obligation to make or Continue, or to Convert Loans of any other Type
into, LIBOR Loans shall be suspended until such time as the Lender may again
make and maintain LIBOR Loans (in which case the provisions of Section 4.5.
shall be applicable).

SECTION 4.4   COMPENSATION.

       The Borrower shall pay to the Lender, upon the request of the Lender,
such amount or amounts as shall be sufficient (in the reasonable opinion of the
Lender) to compensate it for any loss, cost or expense that the Lender
reasonably determines is attributable to:

              (a) any payment or prepayment (whether mandatory or optional) of a
       LIBOR Loan, or Conversion of a LIBOR Loan, made by the Lender for any
       reason (including, without limitation, acceleration) on a date other than
       the last day of the Interest Period for such Loan; or

              (b) any failure by the Borrower for any reason (including,
       without limitation, the failure of any of the applicable
       conditions precedent specified in Article V. to be satisfied) to
       borrow a LIBOR Loan from the Lender on the date for such
       borrowing, or to Convert a Base Rate Loan into a LIBOR Loan or
       Continue a LIBOR Loan on the requested date of such Conversion or
       Continuation,

such compensation to include in the case of a LIBOR Loan, without limitation, an
amount equal to the excess, if any, of (i) the amount of interest that otherwise
would have accrued on the principal amount so paid, prepaid or Converted or not
borrowed for the period from the date of such payment, prepayment, Conversion or
failure to borrow or Convert to the last day of the then current Interest Period
for such Loan (or, in the case of a failure to borrow or Convert, the





                                      -29-
<PAGE>   30

Interest Period for such Loan that would have commenced on the date specified
for such borrowing or Conversion) at the applicable rate of interest for such
Loan provided for herein plus the Lender's normal administrative charges, if
any, associated with such payment, prepayment, Conversion or failure to borrow
over (ii) the amount of interest that otherwise would have accrued on such
principal amount at a rate per annum equal to LIBOR at such time for an amount
comparable to such principal amount and for a maturity comparable to such period
(as reasonably determined by the Lender). Upon the Borrower's request, if the
Lender shall request compensation under this Section, the Lender shall provide
the Borrower with a statement setting forth in reasonable detail the basis for
requesting such compensation and the method for determining the amount thereof.
Any such statement shall be conclusive if made on a reasonable basis and in good
faith.

SECTION 4.5  TREATMENT OF AFFECTED LOANS.

       If the obligation of the Lender to make LIBOR Loans or to Continue, or to
Convert Base Rate Loans into, LIBOR Loans shall be suspended pursuant to Section
4.1.(b), Section 4.2. or Section 4.3., then all LIBOR Loans shall be
automatically Converted into Base Rate Loans on the last day(s) of the then
current Interest Period(s) for LIBOR Loans (or, in the case of a Conversion
required by Section 4.1.(b) or 4.3., on such earlier date as the Lender may
specify to the Borrower) and, unless and until the Lender gives notice as
provided below that the circumstances specified in Section 4.1., Section 4.2. or
4.3. that gave rise to such Conversion no longer exist:

              (a) to the extent that LIBOR Loans have been so Converted, all
       payments and prepayments of principal that would otherwise be applied to
       such LIBOR Loans shall be applied instead to Base Rate Loans; and

              (b) all Loans that would otherwise be made or Continued by the
       Lender as LIBOR Loans shall be made or Continued instead as Base Rate
       Loans, and all Base Rate Loans that would otherwise be Converted into
       LIBOR Loans shall remain as Base Rate Loans.

SECTION 4.6  EFFORTS TO MITIGATE CERTAIN LIABILITY.

       The Lender agrees that it will take reasonable steps to reduce the
liability of the Borrower under, or avoid the results provided under, Sections
4.1 and 4.3., so long as such steps are not disadvantageous to the Lender as
determined by the Lender in its sole discretion.

       (a) no Default or Event of Default shall have occurred and be continuing;

       (b) the representations and warranties made or deemed made by the Loan
Parties in each of the Loan Documents shall be true, complete and correct in all

       (c) the Lender shall have timely received a duly executed Notice of

                   ARTICLE VI. REPRESENTATIONS AND WARRANTIES

SECTION 6.1   REPRESENTATIONS AND WARRANTIES.

       In order to induce the Lender to enter into this Agreement and to make
Loans, the Borrower represents and warrants to the Lender as follows:

       (a) Organization; Power; Qualification. Each of the Loan Parties is a
corporation, duly organized, validly existing and in good standing under the
jurisdiction of its incorporation, has the power and authority to own or lease
its respective properties and to carry on its respective business as now being
and hereafter proposed to be conducted and 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, except where the failure
to be so qualified and in good standing could not reasonably be expected to have
a Material Adverse Effect.

       (b) Ownership Structure. Schedule 6.1.(b) correctly sets forth as of the
Agreement Date the corporate structure of the Borrower and its Subsidiaries, the
correct legal name of the Borrower and each Subsidiary, the Persons holding
equity interests in the Borrower's Subsidiaries and their percentage equity or
voting interest in such Subsidiaries. Except as set forth in such Schedule as of
the Agreement Date: (i) neither the Borrower nor any of its Subsidiaries has
issued to any third party any securities convertible into Borrower's or such
Subsidiary's capital stock or any options, warrants or other rights to acquire
any securities convertible into such capital stock; and (ii) the outstanding
stock and securities of, or other equity interests, as applicable, in the
Borrower's Subsidiaries are owned by the Persons indicated on such Schedule,
free and clear of all Liens, warrants, options and rights of others of any kind
whatsoever. The Shell Subsidiaries were formed only for the purpose of
preserving their respective corporate names. Neither of the Shell Subsidiaries
has conducted any business since the respective date of its formation and
neither of the Shell Subsidiaries has any assets.

       (c) Authorization. The Borrower and each other Loan Party has the right
and power, and has taken all necessary action to authorize it, to execute,
deliver and perform each of the Loan Documents and Acquisition Documents to
which it is a party in accordance with their respective terms and to consummate
the Transactions. Each of the Loan Documents and Acquisition Documents to which
the Borrower or any other Loan Party is a party has been duly executed and
delivered by the duly authorized officers or other representatives of such
Person and each is a legal, valid and binding obligation of such Person
enforceable against such Person in


                                      -34-
<PAGE>   35


accordance with its respective terms, except that the enforceability thereof may
be limited by applicable bankruptcy, reorganization, insolvency, moratorium and
other laws from time to time in effect affecting creditors' rights generally and
general equitable principles.

       (d) Compliance of Documents With Laws, etc. The execution, delivery and
performance of each of the Loan Documents and the Acquisition Documents to which
any Loan Party is a party in accordance with their respective terms and the
consummation of the Transactions do not and will not, by the passage of time,
the giving of notice, or otherwise: (i) require any Governmental Approval, other
than such as already have been obtained and are in full force and effect or
those the failure to obtain which could not reasonably be expected to have a
Material Adverse Effect, or violate any Applicable Law relating to any Loan
Party, other than violations which could not reasonably be expected, singly or
in the aggregate, to have a Material Adverse Effect; (ii) conflict with, result
in a breach of or constitute a default under the articles of incorporation or
the bylaws of the Borrower or the organizational documents of any other Loan
Party, or any indenture, agreement or other instrument to which any Loan Party
is a party or by which it or any of its properties may be bound; or (iii) result
in or require the creation or imposition of any Lien upon or with respect to any
property now owned or hereafter acquired by any Loan Party other than Liens in
favor of the Lender.

       (e) Compliance with Law; Governmental Approvals. The Borrower and each
other Loan Party is in compliance with each Governmental Approval applicable to
it and in compliance with all other Applicable Law relating to the Borrower or
such Loan Party except for noncompliances which, and Governmental Approvals the
failure to possess which, would not, singly or in the aggregate, (i) cause a
Default or Event of Default or (ii) have a Material Adverse Effect.

       (f) Title to Properties; Liens. Each of the Loan Parties has good,
marketable and legal title to, or a valid leasehold interest in, its respective
assets, free and clear of all Liens except for those described in Schedule
6.1.(f) and other Permitted Liens.

       (g) Indebtedness and Guarantees. Schedule 6.1.(g) is, as of the Agreement
Date, a complete and correct listing of all Funded Debt of the Borrower, its
Subsidiaries and the other Loan Parties. No default or event of default, or
event or condition which with the giving of notice, the lapse of time or
otherwise, would constitute such a default or event of default, exists with
respect to any such Indebtedness.

       (h) Material Contracts. Schedule 6.1.(h) is a true, correct and complete
listing of all Material Contracts as of the Agreement Date. No default or event
of default, or event or condition which with the giving of notice, the lapse of
time or otherwise, would constitute such a default or event of default, exists
with respect to any such Material Contract.

       (i) Litigation. There are no actions, suits or proceedings pending (nor,
to the knowledge of the Borrower, are there any actions, suits or proceedings
threatened, nor is there any basis therefor) against or in any other way
relating adversely to or affecting the Borrower or any other Loan Party or any
of its respective property in any court or before any arbitrator of any



                                      -35-
<PAGE>   36

kind or before or by any Governmental Authority which (x) relates to any
Acquisition Document or any Transaction or (y) if adversely determined, could
reasonably be expected to have a Material Adverse Effect. There are no strikes,
slow downs, work stoppages or walkouts or other labor disputes in progress or
threatened relating to the Borrower or any other Loan Party which could
reasonably be expected to have a Material Adverse Effect.

       (j) Taxes. All federal, state and other tax returns of the Borrower, any
of its Subsidiaries or any of the other Loan Parties required by Applicable Law
to be filed have been duly filed, and all federal, state and other taxes,
assessments and other governmental charges or levies upon the Borrower and each
Loan Party and its respective properties, income, profits and assets which are
due and payable have been paid, except any such nonpayment which is at the time
permitted under Section 7.6. As of the Agreement Date, none of the United States
income tax returns of the Borrower, its Subsidiaries or any other Loan Party are
under audit. No tax liens have been filed and no claims are being asserted with
respect to any such taxes. All charges, accruals and reserves on the books of
the Borrower and each of its Subsidiaries in respect of any taxes or other
governmental charges are in accordance with GAAP.

       (k) Financial Statements. The Borrower has furnished to the Lender each
of the following financial statements: (i) audited consolidated balance sheet of
the Borrower and its Subsidiaries as at December 31, 1996, and the related
consolidated statements of income, retained earnings and cash flow for the
fiscal year then ended (the "Historical Financial Statements"); (ii) a pro forma
projected unaudited consolidated balance sheet of the Borrower and its
Subsidiaries as of March 31, 1997 after giving effect to the Transactions being
consummated as of the Effective Date and any Acquisition effected prior to the
Effective Date but after December 31, 1996 (the "Pro Forma Financial
Statements"), and (iii) pro forma projected consolidated financial statements
reflecting the forecasted financial condition and results of operations of the
Borrower and its Subsidiaries on a quarterly and an annual basis for the
five-year period ending March 31, 2001 (the "Projected Financial Statements").
The Historical Financial Statements are complete and correct in all material
respects and fairly present in all material respects the financial condition and
results of operations of the Borrower and its Subsidiaries as of and for the
periods covered thereby. Since December 31, 1996, there has been no material
adverse change in the business, property, assets, liabilities, condition
(financial or otherwise), operations or results of operations of the Borrower
and its Subsidiaries considered as a whole, and after giving effect to each
Transaction each Loan Party will be Solvent. The Pro Forma Financial Statements
fairly present the pro forma financial condition and results of operations of
the Borrower and its Subsidiaries as of and for the periods covered thereby. The
Projected Financial Statements are based on the assumptions set forth in the
supporting schedules thereto and constitute, in the good faith judgment of the
Borrower, reasonable estimations of future performance as of such date. With
respect to any given Acquisition, and except as disclosed by the Borrower to the
Lender in writing, the Borrower is not aware, and the Borrower has no reason to
be aware, that any of the following statements are untrue: (A) the Acquisition
Historical Financial Statements fairly present, in all material respects, the
financial condition and results of operations of the Target as of and for the
periods covered thereby; and (B) the Combined Financial Statements, if any,
delivered under Section 9.6. in connection with such Acquisition, fairly
present, in all material



                                      -36-
<PAGE>   37

respects, the financial condition and results of operations of the Target and
the Company, on a combined basis for the periods covered thereby.

       (l)    ERISA.

              (i)     Each of the Borrower, its Subsidiaries, and each other 
       ERISA Affiliate, is in compliance with all applicable provisions of
       ERISA and the regulations and published interpretations thereunder
       except for noncompliances which could not, singly or in the aggregate,
       reasonably be expected to have a Material Adverse Effect. Each Employee
       Benefit Plan that is intended to be qualified under Section 401(a) of
       the Internal Revenue Code has been determined by the Internal Revenue
       Service to be so qualified, and each trust related to such plan has been
       determined to be exempt under Section 501(a) of the Internal Revenue
       Code. No liability has been incurred by the Borrower, any Subsidiary or
       any other ERISA Affiliate which remains unsatisfied for any taxes or
       penalties with respect to any Employee Benefit Plan or any       
       Multiemployer Plan.

              (ii)    Neither the Borrower, any Subsidiary nor any other ERISA
       Affiliate has (A) engaged in a nonexempt prohibited transaction described
       in Section 4975 of the Internal Revenue Code or Section 406 of ERISA
       affecting any of the Employee Benefit Plans or the trusts created
       thereunder which could subject any such Employee Benefit Plan or trust to
       a tax or penalty on prohibited transactions imposed under Section 4975 of
       the Internal Revenue Code or under ERISA, (B) incurred any accumulated
       funding deficiency with respect to any Employee Benefit Plan, whether or
       not waived, or any other liability to the PBGC which remains outstanding
       other than the payment of premiums and there are no premium payments
       which are due and unpaid, (C) failed to make a required contribution or
       payment to a Multiemployer Plan, or (D) failed to make a required
       installment or other required payment under Section 412 of the Internal
       Revenue Code, Section 302 of ERISA or the terms of such Employee Benefit
       Plan.

              (iii)   No Termination Event has occurred or is reasonably 
       expected to occur with respect to any Pension Plan or Multiemployer
       Plan, and neither the Borrower, any Subsidiary nor any other ERISA
       Affiliate has incurred   any unpaid withdrawal liability with respect to
       any Multiemployer Plan.

              (iv)    The present value of all vested accrued benefits under 
       each Employee Benefit Plan which is subject to Title IV of ERISA, did
       not, as of the most recent valuation date for each such plan, exceed the
       then current     value of the assets of such Employee Benefit Plan
       allocable to such benefits.

              (v)     To the best of the Borrower's knowledge, each Employee 
       Benefit Plan subject to Title IV of ERISA, maintained by the Borrower,
       any Subsidiary or any other ERISA Affiliate, has been administered in
       accordance with its terms in all respects and is in compliance in all
       respects with all applicable requirements of ERISA and other Applicable
       Laws, except where the failure to be so administered or in compliance
       could not reasonably be expected to have a Material Adverse Effect.



                                      -37-
<PAGE>   38
                    
              (vi)  The consummation of the Loans provided for herein will
       not involve any prohibited transaction under ERISA which is not subject
       to a statutory or administrative exemption.

              (vii) No proceeding, claim, lawsuit and/or investigation exists
       or, to the best knowledge of the Borrower after due inquiry, is
       threatened concerning or involving any Employee Benefit Plan which, if
       adversely determined, could reasonably be expected to have a Material
       Adverse Effect.

accordance with GAAP consistently applied throughout the periods involved, the
financial position of the Persons involved as at the date thereof and the
results of operations for such periods. Except for general economic and industry
conditions (as opposed to economic or industry conditions uniquely applicable to
the Borrower and its Subsidiaries because of the nature of the business in which

statements contained therein not misleading.

                                      -42-

such earlier date) and except for changes in factual circumstances specifically
permitted hereunder.

SECTION 6.3   REPRESENTATIONS REGARDING ACQUISITIONS

       (c) Applicable Law. The Lender may exercise all other rights and remedies
it may have under any Applicable Law.

       (d) Appointment of Receiver. To the extent permitted by Applicable Law,
the Lender shall be entitled to the appointment of a receiver for the assets and
properties of the Borrower and its Subsidiaries, 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/or the business
operations of the Borrower and its Subsidiaries and to exercise such power as
the court shall confer upon such receiver.

SECTION 10.3   PERFORMANCE BY LENDER.

       If the Borrower shall fail to perform any covenant, duty or agreement
contained in any of the Loan Documents, the Lender may perform or attempt to
perform such covenant, duty or agreement on behalf of the Borrower after the
expiration of any cure or grace periods set forth herein. In such event, the
Borrower shall, at the request of the Lender, promptly pay any amount reasonably
expended by the Lender in such performance or attempted performance to the
Lender, together with interest thereon at the applicable Post-Default Rate from
the date of such expenditure until paid. Notwithstanding the foregoing, the

SECTION 10.4   RIGHTS CUMULATIVE.

       The rights and remedies of the Lender under this Agreement and each of
the other Loan Documents shall be cumulative and not exclusive of any rights or
remedies which it may otherwise have under Applicable Law. 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.

        (b)    The Lender may assign to one or more Persons, or sell
participations to one or more Persons in, all or a portion of its rights and
obligations hereunder, under the Notes and the other Loan Documents. The Lender
may, in connection with any assignment or proposed assignment or sale or
proposed sale of a participation, disclose to the assignee or proposed assignee
or participant or proposed participant any information relating to the Borrower

of the Lender (and, in the case of an amendment to any Loan Document, the
written consent of the Borrower). No waiver shall extend to or affect any
obligation not expressly waived or impair any right consequent thereon and any
amendment, waiver or consent shall be effective only in the specific instance

omission on the part of the Lender in exercising any right shall operate as a

demand upon the Borrower shall entitle the Borrower to other or further notice
or demand in similar or other circumstances.

the Borrower or any other Loan Party of the proceeds of any of the extensions of
credit hereunder or the past, present or future business activities of the
Borrower or any other Loan Party, including without limitation, the reasonable
fees and disbursements of counsel incurred in connection with any such

         (a)     The Assignor shall at all times duly and punctually perform in

degree the rights or obligations of the parties thereto; and (iii) will not

party thereto, enforceable against the Assignor and each such Person in
accordance with its terms except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting
the rights of creditors generally and by general principles of equity
(regardless of whether enforcement thereof is sought in a proceeding at law or
in equity); provided, however, no representation or warranty is being made with
respect to the enforceability of provisions of such Acquisition Documents
against such other Persons which, if not enforceable, could not reasonably be
expected to have a Material Adverse Effect.

         (c)     Neither the Assignor, nor to the Assignor's knowledge any

irrevocably appoints the Lender as the Assignor's attorney-in-fact, with full

Assignor or otherwise, from time to time upon the occurrence and during the
continuance of an Event of Default in the Lender's discretion, to take any

amounts paid or payable in connection with the Management Agreement Documents.
Upon and after the occurrence and continuation of any Event of Default, all

seek to exercise or enforce, such rights, powers, privileges, authorizations
and benefits in conformity with the provisions of this Agreement.  If the

Assignor shall fail to exercise any right or remedy of the Assignor thereunder,
then, without waiving or releasing the Assignor from any of its





                                      C-4

obligations hereunder or under such Management Agreement Document, the Lender
may (but shall not obligated to) take any action the Lender deems necessary or
desirable to preserve and protect any of the Assignor's rights thereunder or
the Lender's rights thereunder.

         SECTION 6.  REMEDIES.  Upon the occurrence and during the continuation

exercise any or all of the rights available to a secured party under the UCC or
any other Applicable Law; and (b) exercise any or all of its rights and

of this Assignment to the contrary, the Assignor expressly acknowledges and
agrees that it shall continue to observe and perform in accordance with the
terms of the Management Agreement Documents all of the conditions and
obligations therein contained to be observed and performed by it, and that
neither this Assignment, nor any action taken pursuant hereto, shall cause the
Lender to be under any obligation or liability in any respect whatsoever to any
party to any of the Management Agreement Documents or to any other Person for
the observance or performance of any of the representations, warranties,
conditions, covenants, agreements or terms contained in any of the Management
Agreement Documents or any other document, instrument or agreement relating
thereto.

upon the written request of the Lender, and at the sole expense of the
Assignor, the Assignor will promptly execute and deliver such further
instruments and documents and take such further action as the Lender may
reasonably request for the purpose of obtaining or preserving the full benefits
of this Agreement and of the rights and powers herein granted.

         SECTION 9.  RIGHTS CUMULATIVE.  The rights and remedies of the Lender
under this Agreement are cumulative and not exclusive of any rights or remedies
which it would otherwise have.  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 10.  LENDER APPOINTED ATTORNEY-IN-FACT.  The Assignor hereby
irrevocably appoints the Lender as the Assignor's attorney-in-fact, with full
authority in the place and stead of the Assignor and in the name of the
Assignor or otherwise, from time to time upon the occurrence and during the
continuation of an Event of Default 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 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; (ii) to
receive, endorse, and collect any drafts or other instruments, documents and
chattel paper in connection with clause (i) above and (iii) to file any claims
or take any action or institute any proceedings

<PAGE>   89

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 is irrevocable and
coupled with an interest.

         SECTION 11.  EXPENSES.  The Assignor will pay, within 10 days of
demand, all reasonable fees and expenses actually incurred by the Lender in
connection with (a) the collection or enforcement of the Obligations including
the reasonable fees and disbursements of counsel to the Lender actually
incurred by the Lender and (b) the exercise by the Lender of any right or
remedy granted to it under this Agreement if such exercise is done by, through
or with the assistance of any attorney.

         SECTION 12.  NOTICES.  Notices, requests and other communications
required or permitted hereunder shall be given in accordance with the
applicable terms of the Guaranty.

         SECTION 13.  INDEMNIFICATION.  The Assignor agrees to indemnify and
hold the Lender harmless from and against any claim, loss, damage, action,
cause of action, liability, cost and expense or suit of any kind or nature
whatsoever (an "Indemnified Claim"), brought against or incurred by the Lender
in any manner arising out of or, directly or indirectly, related to or
connected with this Agreement, including without limitation, the exercise by
the Lender of any of its rights and remedies under this Agreement or under any
of the Management Agreement Documents or any other action taken by the Lender
pursuant to the terms of this Agreement; provided, however, the Assignor shall
not be obligated to indemnify or hold harmless the Lender from any Indemnified
Claim to the extent that it results from the Lender's gross negligence or
willful misconduct.  The Lender agrees to give the Assignor prompt notice of
any suit or cause of action brought against the Lender which is covered by this
Section.

         SECTION 14.  TERMINATION.  Upon indefeasible payment in full of all of
the Obligations, this Agreement shall terminate.

         SECTION 15.  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 16.  AMENDMENTS, ETC.  No amendment or waiver of any provision
of this Agreement, nor consent to any departure by the 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.

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

                                FORM OF GUARANTY


         THIS GUARANTY dated as of ____________, _____ (this "Guaranty"),
executed by [NAME OF LOAN PARTY], a _________________ organized under the laws
of _____________ (the "Guarantor"), in favor of NATIONSBANK, N.A. (SOUTH) (the
"Lender").

         WHEREAS, Physicians' Specialty Corp. (the "Borrower") and the Lender
have entered into that certain Credit Agreement dated as of April ___, 1997 (as
amended, supplemented, restated or otherwise modified from time to time in
accordance with its terms, the "Credit Agreement"), pursuant to which the
Lender has agreed, subject to the terms thereof, to extend certain financial
accommodations to the Borrower; and

         WHEREAS, the Borrower owns, directly or indirectly, all of the issued
and outstanding capital stock of, or other equity interests in, the Guarantor;

         WHEREAS, the Guarantor and the other Subsidiaries of the Borrower,
though separate legal entities, are mutually dependent on each other in the
conduct of their respective businesses as an integrated operation and have
determined it to be in their mutual best interests to obtain financing from the
Lender through their collective efforts;

         WHEREAS, the Guarantor acknowledges that it will receive direct and
indirect benefits from the Lender making such financial accommodations
available to the Borrower under the Credit Agreement and, accordingly, the
Guarantor is willing to guarantee the Borrower's obligations to the Lender on
the terms and conditions contained herein; and

         WHEREAS, the Guarantor's execution and delivery of this Guaranty is
one of the conditions precedent to the Lender making, or continuing to make,
such financial accommodations to the Borrower;

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the Guarantor, the Guarantor
agrees as follows:

         SECTION 1.  GUARANTY.  The Guarantor hereby absolutely, irrevocably
and unconditionally guaranties the due and punctual payment and performance
when due, whether at stated maturity, by acceleration or otherwise, of all of
the following (collectively referred to as the "Guarantied Obligations"):  (a)
all indebtedness and obligations owing by the Borrower to the Lender under or
in connection with the Credit Agreement and any other Loan Document to which
the Borrower is a party, including without limitation, the repayment of all
principal of the Loans and the payment of all interest, fees, charges,
reasonable attorneys' fees and other amounts payable to the Lender thereunder
or in connection therewith; (b) any and all extensions, renewals,
modifications, amendments or substitutions of the foregoing; (c) all expenses,
including without limitation, reasonable attorneys' fees and disbursements,
that are actually incurred by the Lender





                                      D-1
<PAGE>   95

in the enforcement of any of the foregoing or any obligation of the Guarantor
hereunder; and (d) all other Obligations of the Borrower.

         SECTION 2.  GUARANTY OF PAYMENT AND NOT OF COLLECTION.  This Guaranty
is a guaranty of payment, and not of collection, and a debt of the Guarantor
for its own account.  Accordingly, the Lender shall not be obligated or
required before enforcing this Guaranty against the Guarantor: (a)  to pursue
any right or remedy the Lender may have against any other Loan Party or any
other Person or commence any suit or other proceeding against any other Loan
Party or any other Person in any court or other tribunal; (b) to make any claim
in a liquidation or bankruptcy of any other Loan Party or any other Person; or
(c) to make demand of any other Loan Party or any other Person or to enforce or
seek to enforce or realize upon any collateral security held by the Lender
which may secure any of the Guarantied Obligations.  In this connection, the
Guarantor hereby waives the right of the Guarantor to require any holder of the
Guarantied Obligations to take action against the Borrower as provided in
Official Code of Georgia Annotated Section 10-7-24.

         SECTION 3.  GUARANTY ABSOLUTE.  The Guarantor guarantees that the
Guarantied Obligations will be paid strictly in accordance with the terms of
the documents evidencing the same, regardless of any Applicable Law now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Lender with respect thereto.  The liability of the Guarantor
under this Guaranty shall be absolute and unconditional in accordance with its
terms and shall remain in full force and effect without regard to, and shall
not be released, suspended, discharged, terminated or otherwise affected by,
any circumstance or occurrence whatsoever, including without limitation, the
following (whether or not the Guarantor consents thereto or has notice
thereof):

         (a)     (i) any change in the amount, interest rate or due date or
other term of any of the Guarantied Obligations, (ii) any change in the time,
place or manner of payment of all or any portion of the Guarantied Obligations,
(iii) any amendment or waiver of, or consent to the departure from or other
indulgence with respect to, the Credit Agreement, any other Loan Document, or
any other document or instrument evidencing or relating to any Guarantied
Obligations, or (iv) any waiver, renewal, extension, addition, or supplement
to, or deletion from, or any other action or inaction under or in respect of,
the Credit Agreement, any of the other Loan Documents, or any other documents,
instruments or agreements relating to the Guarantied Obligations or any other
instrument or agreement referred to therein or evidencing any Guarantied
Obligations or any assignment or transfer of any of the foregoing;

         (b)     any lack of validity or enforceability of the Credit
Agreement, any of the other Loan Documents, or any other document, instrument
or agreement referred to therein or evidencing any Guarantied Obligations or
any assignment or transfer of any of the foregoing;

         (c)     any furnishing to the Lender of any security for the
Guarantied Obligations, or any sale, exchange, release or surrender of, or
realization on, any collateral securing any of the Guarantied Obligations;





                                      D-2
<PAGE>   96

         (d)     any settlement or compromise of any of the Guarantied
Obligations, any security therefor, or any liability of any other party with
respect to the Guarantied Obligations, or any subordination of the payment of
the Guarantied Obligations to the payment of any other liability of the
Borrower or any other Loan Party;

         (e)     any bankruptcy, insolvency, reorganization, composition,
adjustment, dissolution, liquidation or other like proceeding relating to the
Guarantor, any other Loan Party or any other Person, or any action taken with
respect to this Guaranty by any trustee or receiver, or by any court, in any
such proceeding;

         (f)     any act or failure to act by the Borrower or any other Person
which may adversely affect the Guarantor's subrogation rights, if any, against
the Borrower to recover payments made under this Guaranty;

         (g)     any application of sums paid by any other Loan Party or any
other Person with respect to the liabilities of the Borrower to the Lender,
regardless of what liabilities of such Borrower remain unpaid;

         (h)     any defect, limitation or insufficiency in the borrowing
powers of the Borrower or in the exercise thereof; or

         (i)     any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Guarantor hereunder.

         SECTION 4.  ACTION WITH RESPECT TO OBLIGATIONS.  The Lender may, at
any time and from time to time, without the consent of, or notice to, the
Guarantor, and without discharging the Guarantor from its obligations hereunder
take any and all actions described in Section 3. and may otherwise: (a) amend,
modify, alter or supplement the terms of any of the Guarantied Obligations,
including, but not limited to, extending or shortening the time of payment of
any of the Guarantied Obligations or changing the interest rate that may accrue
on any of the Guarantied Obligations; (b) amend, modify, alter or supplement
the Credit Agreement or any other Loan Document; (c) sell, exchange, release or
otherwise deal with all, or any part, of any collateral securing any of the
Guarantied Obligations; (d) release any Loan Party or other Person liable in
any manner for the payment or collection of the Guarantied Obligations; (e)
exercise, or refrain from exercising, any rights against any other Loan Party
or any other Person; and (f) apply any sum, by whomsoever paid or however
realized, to the Guarantied Obligations in such order as the Lender shall elect.

         SECTION 5.  REPRESENTATIONS AND WARRANTIES.  The Guarantor hereby
makes to the Lender all of the representations and warranties made by the
Borrower with respect to or in any way relating to the Guarantor in the Credit
Agreement and the other Loan Documents, as if the same were set forth herein in
full.





                                      D-3
<PAGE>   97

         SECTION 6.  COVENANTS.  The Guarantor will comply with all covenants
which the Borrower is to cause the Guarantor to comply with under the terms of
the Credit Agreement or any of the other Loan Documents.

         SECTION 7.  WAIVER.  The Guarantor, to the fullest extent permitted by
Applicable Law, hereby waives notice of acceptance hereof or any presentment,
demand, protest or notice of any kind, and any other act or thing, or omission
or delay to do any other act or thing, which in any manner or to any extent
might vary the risk of the Guarantor or which otherwise might operate to
discharge the Guarantor from its obligations hereunder.

         SECTION 8.  INABILITY TO ACCELERATE.  If the Lender is prevented under
Applicable Law or otherwise from demanding or accelerating payment of any of
the Guarantied Obligations by reason of any automatic stay or otherwise, the
Lender shall be entitled to receive from the Guarantor, upon demand therefor,
the sums which otherwise would have been due had such demand or acceleration
occurred.

         SECTION 9.  REINSTATEMENT OF OBLIGATIONS.  If claim is ever made on
the Lender for repayment or recovery of any amount or amounts received in
payment or on account of any of the Guarantied Obligations, and the Lender
repays all or part of said amount by reason of (a) any judgment, decree or
order of any court or administrative body of competent jurisdiction, or (b) any
settlement or compromise of any such claim effected by the Lender with any such
claimant (including the Borrower or a trustee in bankruptcy for the Borrower),
then and in such event the Guarantor agrees that any such judgment, decree,
order, settlement or compromise shall be binding on it, notwithstanding any
revocation hereof or the cancellation of the Credit Agreement, any of the other
Loan Documents, or any other instrument evidencing any liability of the
Borrower, and the Guarantor shall be and remain liable to the Lender for the
amounts so repaid or recovered to the same extent as if such amount had never
originally been paid to the Lender.

         SECTION 10.  SUBROGATION.  Upon the making by the Guarantor of any
payment hereunder for the account of the Borrower, the Guarantor shall be
subrogated to the rights of the payee against such Borrower; provided, however,
that the Guarantor shall not enforce any right or receive any payment by way of
subrogation or otherwise take any action in respect of any other claim or cause
of action the Guarantor may have against the Borrower arising by reason of any
payment or performance by the Guarantor pursuant to this Guaranty, unless and
until all of the Guarantied Obligations have been indefeasibly paid and
performed in full.  If any amount shall be paid to the Guarantor on account of
or in respect of such subrogation rights or other claims or causes of action,
the Guarantor shall hold such amount in trust for the benefit of the Lender and
shall forthwith pay such amount to the Lender to be credited and applied
against the Guarantied Obligations, whether matured or unmatured, in accordance
with the terms of the Credit Agreement or to be held by the Lender as
collateral security for any Guarantied Obligations existing.

         SECTION 11.  PAYMENTS FREE AND CLEAR.  All sums payable by the
Guarantor hereunder, whether of principal, interest, fees, expenses, premiums
or otherwise, shall be paid in full, without set-off or counterclaim or any
deduction or withholding whatsoever (including any





                                      D-4
<PAGE>   98

Taxes), and if the Guarantor is required by Applicable Law or by any
Governmental Authority to make any such deduction or withholding, the Guarantor
shall pay to the Lender such additional amount as will result in the receipt by
the Lender of the full amount payable hereunder had such deduction or
withholding not occurred or been required.

         SECTION 12.  SET-OFF.  In addition to any rights now or hereafter
granted under any of the other Loan Documents or Applicable Law and not by way
of limitation of any such rights, the Guarantor hereby authorizes the Lender,
at any time or from time to time, without any prior notice to the Guarantor or
to any other Person, any such notice being hereby expressly waived, to set-off
and to appropriate and to apply any and all deposits (general or special,
including, but not limited to, indebtedness evidenced by certificates of
deposit, whether matured or unmatured) and any other indebtedness at any time
held or owing by the Lender, or any affiliate of the Lender, to or for the
credit or the account of the Guarantor against and on account of any of the
Guarantied Obligations, although such obligations shall be contingent or
unmatured.

         SECTION 13.  SUBORDINATION.  The Guarantor hereby expressly covenants
and agrees for the benefit of the Lender that all obligations and liabilities
of the Borrower to the Guarantor of whatever description, including without
limitation, all intercompany receivables of the Guarantor from the Borrower
(collectively, the "Junior Claims") shall be subordinate and junior in right of
payment to all Guarantied Obligations.  If an Event of Default shall have
occurred and be continuing, then the Guarantor shall not accept any direct or
indirect payment (in cash, property, securities by setoff or otherwise) from
the Borrower on account of or in any manner in respect of any Junior Claim
until all of the Guarantied Obligations have been indefeasibly paid in full.

         SECTION 14.  AVOIDANCE PROVISIONS.  It is the intent of the Guarantor
and the Lender that in any Proceeding, the Guarantor's maximum obligation
hereunder shall equal, but not exceed, the maximum amount which would not
otherwise cause the obligations of the Guarantor hereunder (or any other
obligations of the Guarantor to the Lender) to be avoidable or unenforceable
against the Guarantor in such Proceeding as a result of Applicable Law,
including without limitation, (a) Section 548 of the Bankruptcy Code of 1978,
as amended (the "Bankruptcy Code") and (b) any state fraudulent transfer or
fraudulent conveyance act or statute applied in such Proceeding, whether by
virtue of Section 544 of the Bankruptcy Code or otherwise.  The Applicable Laws
under which the possible avoidance or unenforceability of the obligations of
the Guarantor hereunder (or any other obligations of the Guarantor to the
Lender) shall be determined in any such Proceeding are referred to as the
"Avoidance Provisions".  Accordingly, to the extent that the obligations of the
Guarantor hereunder would otherwise be subject to avoidance under the Avoidance
Provisions, the maximum Guarantied Obligations for which the Guarantor shall be
liable hereunder shall be reduced to that amount which, as of the time any of
the Guarantied Obligations are deemed to have been incurred under the Avoidance
Provisions, would not cause the obligations of the Guarantor hereunder (or any
other obligations of the Guarantor to the Lender), to be subject to avoidance
under the Avoidance Provisions.  This Section is intended solely to preserve
the rights of the Lender hereunder to the maximum extent that would not cause
the obligations of the Guarantor hereunder to be subject to avoidance under the
Avoidance Provisions, and neither the Guarantor nor any other Person shall have
any right or claim under this Section as against the Lender that would not
otherwise be available to such Person under the Avoidance Provisions.

<PAGE>   99

         SECTION 15.  INFORMATION.  The Guarantor assumes all responsibility
for being and keeping itself informed of the financial condition of the Loan
Parties, and of all other circumstances bearing upon the risk of nonpayment of
any of the Guarantied Obligations and the nature, scope and extent of the risks
that the Guarantor assumes and incurs hereunder, and agrees that neither the
Lender nor any Lender shall have any duty whatsoever to advise the Guarantor of
information regarding such circumstances or risks.

         SECTION 16.  GOVERNING LAW.  THIS GUARANTY SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA.

         SECTION 17.  DISPUTE RESOLUTION.  ANY CONTROVERSY OR CLAIM BETWEEN THE
GUARANTOR AND THE LENDER, INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR
RELATING TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT, INCLUDING ANY CLAIM BASED
ON OR 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 JUDICIAL ARBITRATION AND MEDIATION SERVICES, INC.
(J.A.M.S.), OR THE COMMERCIAL ARBITRATION RULES OF THE AMERICAN ARBITRATION
ASSOCIATION, AS APPLICABLE, 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 GUARANTY MAY BRING AN ACTION, INCLUDING A SUMMARY OR EXPEDITED
PROCEEDING, TO COMPEL ARBITRATION OF ANY CONTROVERSY OR CLAIM TO WHICH THIS
GUARANTY APPLIES IN ANY COURT HAVING JURISDICTION OVER SUCH ACTION.

         A.      SPECIAL RULES.  THE ARBITRATION SHALL BE CONDUCTED IN THE CITY
OF THE GUARANTOR'S DOMICILE AT THE TIME OF THIS GUARANTY'S EXECUTION AND
ADMINISTERED BY J.A.M.S. OR THE AMERICAN ARBITRATION ASSOCIATION AS AGREED BY
THE PARTIES.  ALL ARBITRATION HEARINGS WILL BE COMMENCED WITHIN 90 DAYS OF THE
DEMAND FOR ARBITRATION; FURTHER, THE ARBITRATOR(S) SHALL ONLY, UPON A SHOWING
OF CAUSE, BE PERMITTED TO EXTEND THE COMMENCEMENT OF SUCH HEARING FOR UP TO AN
ADDITIONAL 60 DAYS.

         B.      RESERVATION OF RIGHTS.  NOTHING IN THIS AGREEMENT SHALL BE
DEEMED TO (I) LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF
LIMITATION OR REPOSE AND ANY WAIVERS CONTAINED IN THIS GUARANTY; OR (II) BE A
WAIVER BY THE LENDER OF THE PROTECTION AFFORDED TO IT BY 12 U.S.C. SEC. 91 OR
ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR (III) LIMIT THE RIGHT OF THE LENDER

dispute relating to any of the outstanding amount, payment or receipt of any of
the Guarantied Obligations or otherwise, the entries in such books and accounts
shall, absent manifest error, constitute conclusive evidence of the outstanding
amount of such Guarantied Obligations and the amounts paid and payable with

shall not in any way relieve or discharge the Guarantor of any of its
obligations hereunder.

         SECTION 19.  WAIVER OF REMEDIES.  No delay or failure on the part of
the Lender in the exercise of any right or remedy it may have against the

single or partial exercise by the Lender of any such right or remedy shall
preclude other or further exercise thereof or the exercise of any other such
right or remedy.

         SECTION 20.  TERMINATION.  This Guaranty shall remain in full force
and effect until the indefeasible payment in full of the Guarantied Obligations
and the termination or cancellation of the Credit Agreement.

         SECTION 21.  SUCCESSORS AND ASSIGNS.  Each reference herein to the
Lender shall be deemed to include the Lender's permitted successors and assigns
(including, but not limited to, any holder of the Guarantied Obligations) in
whose favor the provisions of this Guaranty also shall inure, and each
reference herein to the Guarantor shall be deemed to include the Guarantor's
successors and assigns, upon whom this Guaranty also shall be binding.  The
Lender may, in accordance with the applicable provisions of the Credit
Agreement, assign, transfer or sell any Guarantied Obligations, or grant or
sell participations in any Guarantied Obligations, to any Person without the
consent of, or notice to, the Guarantor and without releasing, discharging or
modifying the Guarantor's obligations hereunder.  The Guarantor hereby consents
to the delivery by the Lender to any assignee or participant (or any
prospective assignee or participant) of any financial or other information
regarding the Guarantor to the extent permitted by and in accordance with the
Credit Agreement, including, without limitation, the confidentiality provisions
therein.  The Guarantor may not assign or transfer its obligations hereunder to

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the parties hereto, the parties
hereto agree as follows:





                                      H-1
<PAGE>   111

         Section 1.  Subordination of Debt.  The Junior Creditor agrees and
covenants that, to the extent set forth herein and on the terms and conditions
set forth herein, the Subordinated Debt is and shall be subordinate in right of
payment and collection to the payment in full of all of the Senior Debt.  The
Debtor shall not make, and the Junior Creditor shall not accept, any payment
with respect to, or on account of, any of the Subordinated Debt; provided,
however, so long as the Junior Creditor shall have not received a notice from
the Lender that an Event of Default under and as defined in the Credit
Agreement has occurred and is continuing, the Debtor may pay, and the Junior
Creditor may receive, regularly scheduled payments of interest and principal on
the Subordinated Note, as such Subordinated Note may be amended with the
consent of the Lender.  In no event shall the Junior Creditor be entitled to
receive any prepayments of principal or interest in respect of any of the
Subordinated Debt.

         Section 2.  Subordination of Security Interest.  Irrespective of the
order of the execution of any security agreement or the filing of any financing
statements or the lapse thereof or the physical possession of any collateral,
or of the order or method of attachment or perfection of any security interest
or other lien in the Lender Collateral or the Junior Creditor Collateral, and
irrespective of anything contained in any filing or agreement to which the
Lender or the Junior Creditor may now or hereinafter be a party, all of the
rights, claims, liens and security interests, if any, of the Junior Creditor,
whether now existing or hereinafter acquired, arising in any of the Lender
Collateral shall be and are hereby made subject, subordinate and inferior to
the rights, claims, liens and security interests of the Lender, whether now
existing or hereinafter acquired, arising in any of the Lender Collateral.
Accordingly, the proceeds of any repossession, setoff, foreclosure or other
judicial sale or any other disposition of the Lender Collateral shall be
applied first to the payment in full of all amounts owing to the Lender with
respect to the Senior Debt.

         Section 3.  No Action.  Unless and until the Senior Debt shall have
been paid in full, the Junior Creditor shall not, without the prior written
consent of the Lender and whether or not an Event of Default under and as
defined in the Credit Agreement shall have occurred and be continuing, commence
any action or proceeding seeking in any way to collect on the Subordinated
Debt, or commence, or join with any other creditor (other than the Lender) in
commencing, a Bankruptcy Proceeding and if taken any such action shall be
ineffective or if in process of being taken shall be terminated and rescinded.
Not in limitation of the foregoing, the Junior Creditor shall not demand,
institute an action for, take, receive or repossess from the Debtor or any
other person whether by court proceeding, self-help, repossession, setoff or
otherwise, the whole or any portion of the Junior Creditor Collateral or
foreclose upon the whole or any portion of the Junior Creditor Collateral,
whether by judicial action, public or private sale, by notification of account
debtors, by power of sale or otherwise, without first obtaining the prior
written consent of the Lender.

         Section 4.  Bankruptcy of Debtor.  In the event of any Bankruptcy
Proceeding, the Junior Creditor will, at the request of the Lender, file any
claim, proof of claim, or other instrument of similar character necessary to
enforce the obligations of the Debtor in respect of the Subordinated Debt and
will hold in trust for the Lender and assign, transfer and pay over to the
Lender, in the form received, to be applied on the Senior Debt, any and all
monies, dividends or other assets received in any such Bankruptcy Proceeding on
account of the Subordinated Debt, unless and until the Senior Debt shall have
been paid in full.  If the Junior Creditor shall fail to





                                      H-2
<PAGE>   112

take such action requested by the Lender, the Lender may, as attorney-in-fact
for the Junior Creditor, take such action on behalf of the Junior Creditor, and
the Junior Creditor hereby appoints the Lender and any of its officers as
attorney-in-fact for the Junior Creditor to demand, sue for, collect and
receive any and all such monies, dividends or other assets and give acquittance
therefor and to file any claim, proof of claim or other instrument of similar
character and to take any such action in any Bankruptcy Proceeding in the
Lender's own name or in the name of the Junior Creditor as the Lender may deem
necessary or advisable for the enforcement of this Agreement.  The Junior
Creditor will execute and deliver to the Lender such other and further powers
of attorney or other instruments as the Lender may request in order to
accomplish the foregoing.  The Junior Creditor further grants to the Lender an
irrevocable proxy to exercise any voting rights the Junior Creditor may have
with respect to the approval or disapproval of a plan of reorganization of the
Debtor proposed by any person or class of persons in any Bankruptcy Proceeding.

         Section 5.  Warranties and Representations of the Junior Creditor.
The Junior Creditor represents and warrants to the Lender that: (a) no part of
the Subordinated Debt is evidenced by any instrument other than the
Subordinated Note; (b) except for the Junior Creditor's security interest in
the Junior Creditor Collateral, none of the Subordinated Debt is secured by any
security interest, lien or other encumbrance in any of the assets of the Debtor
or any other person or entity; (c) the Junior Creditor is the lawful owner of
the Subordinated Debt; (d) the Junior Creditor has not assigned or transferred
any of the Subordinated Debt, or any interest therein; (e) the Junior Creditor
has not given any subordination in respect of the Subordinated Debt; and (f) no
default is in existence with respect to the Subordinated Debt.

         Section 6.  Covenants.  For so long as this Agreement is in effect the
Junior Creditor agrees that it will not: (a) accept any instrument, security or
other writing evidencing any part of the Subordinated Debt other than the
Subordinated Note, (b) amend, alter or modify any provision of the Subordinated
Note without the prior written consent of the Lender or (c) except for the
Junior Creditor's security interest in the Junior Creditor Collateral, accept
any security interest, lien or other encumbrance in any of the assets of the
Debtor or any other person or entity as security for any of the Subordinated
Debt.

         Section 7.  Turnover of Prohibited Transfers.  If the Junior Creditor
shall receive any payment or other transfer of property which it is not
entitled to receive or accept under the terms hereof, the Junior Creditor shall
forthwith deliver same to the Lender in the form received (together with any
endorsement necessary to effect a transfer of all rights therein to the Lender)
for application to the Senior Debt.  The Junior Creditor irrevocably authorizes
the Lender to supply any required endorsement or assignment which may have been
omitted.  Until so delivered any such payment or property shall be held by the
Junior Creditor in trust for the Lender and shall not be commingled with other
funds or property of the Junior Creditor.

         Section 8.  Waivers.  To the fullest extent permitted by law, the
Junior Creditor each hereby waives the right to require the Lender to marshal
any assets, or to enforce any security interest or lien the Lender may now or
hereafter have in any collateral securing the Senior Debt or to pursue any
claim it may have against any guarantor of the Senior Debt, as a condition to
the Lender's entitlement to receive any payment on account of the Subordinated
Debt.  The Lender





                                      H-3
<PAGE>   113

may, at any time and from time to time, without the consent of or notice to the
Junior Creditor and without incurring any responsibility or liability to the
Junior Creditor and without impairing or releasing the obligations of the
Junior Creditor hereunder:  (a) change the manner, place or terms of payment or
change or extend the time of payment of or renew or alter the Senior Debt or
any portion thereof; (b) sell, exchange, release or otherwise deal with any
collateral or any other property by whomsoever at any time pledged or mortgaged
to secure, or however securing, the Senior Debt or any portion thereof; (c)
release anyone liable in any manner for the payment or collection of the Senior
Debt or any portion thereof; (d) exercise or refrain from exercising any rights
against the Debtor and others; and (e) apply any sums by whomsoever paid or
however realized to the Senior Debt or any portion thereof.

         Section 9.  Validity of Subordinated Debt.  This Agreement defines the
relative rights of the Junior Creditor and the Lender.  Nothing in this
Agreement shall impair, as between the Debtor and the Junior Creditor, the
obligation of the Debtor, which is absolute and unconditional, to pay the
Subordinated Debt in accordance with its terms, except as payment thereof may
be postponed or otherwise directed in accordance with this Agreement.

         Section 10.  Specific Performance.  In addition to any other remedies
available to the Lender hereunder or otherwise, at any time the Junior Creditor
fails to comply with any provision of this Agreement applicable to the Junior
Creditor, the Lender may demand specific performance of this Agreement.  The
Junior Creditor hereby irrevocably waives any defense based on the adequacy of
a remedy at law that might be asserted as a bar to such remedy of specific
performance.  If the Junior Creditor, in violation of this Agreement, shall
institute or participate in any action, suit or proceeding against the Debtor,
the Debtor may interpose as a defense or dilatory plea this Agreement and the
Lender is irrevocably authorized to intervene and to interpose such defense or
plea in the Debtor's name.

         Section 11.  Indulgences Not Waivers.  Neither the failure nor any
delay on the part of the Lender to exercise any right, remedy, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, remedy, power or privilege with respect to any
occurrence be construed as a waiver of such right, remedy, power or privilege
with respect to any other occurrence.  No waiver by a party hereunder shall be
effective unless it is in writing and signed by the party making such waiver,
and then only to the extent specifically stated in such writing.

         Section 12.  Duration.  This Agreement shall become effective when
executed by the Debtor and the Junior Creditor and accepted by the Lender, and,
when so accepted, shall constitute a continuing agreement of subordination, and
shall remain in effect until all of the Senior Debt has been paid in full.

         Section 13.  LITIGATION.  IN THE EVENT OF ANY LITIGATION WITH RESPECT
TO ANY MATTER CONCERNED WITH THIS AGREEMENT OR THE SENIOR DEBT, THE JUNIOR
CREDITOR AND THE LENDER EACH HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY.  THE
JUNIOR CREDITOR HEREBY IRREVOCABLY CONSENTS TO THE JURISDICTION OF THE COURTS
OF THE STATE OF GEORGIA AND OF ANY FEDERAL COURT LOCATED IN THE STATE OF
GEORGIA, IN CONNECTION WITH





                                      H-4

ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY OR ALL OF THE SENIOR
DEBT OR THIS AGREEMENT.

         Section 14.  Adequate Assurances.  The Junior Creditor agrees to
execute any further documents, instruments and agreements and take such other
actions as may be necessary to effect the purposes of this Agreement, including
the filing of any financing statements or other instruments in any applicable
public records, all as directed by the Lender.  The Junior Creditor agrees that

evidencing the Subordinated Debt, and each document or instrument creating or
otherwise evidencing the Junior Creditor's security interest in the Junior
Creditor Collateral, the following legend:

as follows:

         SECTION 1.  PLEDGE.  The Pledgor hereby pledges, hypothecates,

any of the foregoing, together with any and all other rights, titles,
interests, powers, privileges and preferences pertaining to said property.

         SECTION 2.  OBLIGATIONS SECURED.  This Agreement is made, and the

the Pledged Collateral are located at ___________________, ______ County,

sentence of this Section 3(c).  The Social Security number, or the Internal
Revenue Service taxpayer identification number, as applicable, of the Pledgor

         (d)     Authority, etc.  The Pledgor (i) has the power and authority
to pledge the Collateral in the manner hereby done or contemplated and (ii)
will defend its title or interest thereto or therein against any and all Liens
(other than the Lien created by this Pledge Agreement and Permitted Liens),
however arising, of all persons.

         (e)     No Approval.  No consent or approval of any Governmental
Authority or any securities exchange was or is necessary to the validity of the

stock of [the] [each] Issuer.

         SECTION 4.  COVENANTS.  The Pledgor hereby unconditionally covenants
and agrees as follows:

         (a)     No Liens; No Sale of Pledged Collateral.  The Pledgor will not
create, assume, incur or permit or suffer to exist or to be created, assumed or
incurred, any Lien on any of the Pledged Collateral (or any interest therein),
other than Permitted Liens, and will not, without the prior written consent of
the Pledgee, sell, lease, assign, transfer or otherwise dispose of all or any
portion of the Pledged Collateral (or any interest therein).

         (b)     Change of Locations, Name, Etc.  Without giving the Pledgor
sixty-day's prior written notice, the Pledgor will not (i) change the Pledgor's
chief executive office, principal place of business, or the location of its
books and records relating to the Pledged Collateral or (ii) change its name,
identity or structure.

         SECTION 5.  ADDITIONAL SHARES.

         (a)     During the period this Pledge Agreement is in effect, the
Pledgor shall not permit any Issuer to issue any additional shares of capital
stock or other equity securities or interests to any Person other than the

its articles or certificate of incorporation in a manner which would affect the
voting, liquidation, preference or other rights of a holder of the shares of
stock pledged hereunder.





                                      K-3
<PAGE>   125

         (b)     The Pledgor agrees that, until this Pledge Agreement has
terminated in accordance with its terms, any additional Securities of an Issuer
at any time issued to the Pledgor or otherwise acquired by the Pledgor shall be
promptly delivered or otherwise transferred to the Pledgee as additional
Pledged Collateral and shall be subject to the Lien of, and the terms and
conditions of, this Pledge Agreement.

         SECTION 6.  REGISTRATION IN NOMINEE NAME, DENOMINATIONS.  The Pledgee
shall have the right (in its sole and absolute discretion) to hold the Pledged
Securities in its own name as pledgee, the name of its nominee (as Pledgee or
as sub-agent) or the name of the applicable Pledgor, endorsed or assigned in
blank or in favor of the Pledgee.  The Pledgor will promptly give to the
Pledgee copies of any notices or other communications received by it with
respect to Pledged Securities registered in the name of the Pledgor.  The
Pledgee shall at all times have the right to exchange the certificates
representing Pledged Securities for certificates of smaller or larger numbers
of shares for any purpose consistent with this Pledge Agreement.

         SECTION 7.  VOTING RIGHTS; DIVIDENDS, ETC.

         (a)     So long as no Event of Default shall have occurred and be
continuing:

                 (i)      the Pledgor shall be entitled to exercise any and all
         voting and/or consensual rights and powers accruing to an owner of the
         Pledged Collateral or any part thereof for any purpose not
         inconsistent with the terms and conditions of this Pledge Agreement or
         any agreement giving rise to or otherwise relating to any of the
         Secured Obligations; provided, however, that the Pledgor shall not
         exercise, or refrain from exercising, any such right or power if any
         such action would have a materially adverse effect on the value of
         such Pledged Collateral in the reasonable judgment of the Pledgee;

                 (ii)     the Pledgor shall be entitled to retain and use any
         and all cash dividends paid on the Pledged Collateral, but any and all
         stock and/or liquidating dividends, other distributions in property,
         return of capital or other distributions made on or in respect of
         Pledged Securities, whether resulting from a subdivision, combination
         or reclassification of outstanding Securities of an Issuer which are
         pledged hereunder or received in exchange for Pledged Collateral or
         any part thereof or as a result of any merger, consolidation,
         acquisition or other exchange of assets or on the liquidation, whether
         voluntary or involuntary, of an Issuer, or otherwise, shall be and
         become part of the Pledged Collateral pledged hereunder and, if
         received by the Pledgor, shall forthwith be delivered to the Pledgee
         to be held as collateral subject to the terms and conditions of this
         Pledge Agreement.

The Pledgee agrees to execute and deliver to the Pledgor, or cause to be
executed and delivered to the Pledgor, as appropriate, at the sole cost and
expense of the Pledgor, all such proxies, powers of attorney, dividend orders
and other instruments as the Pledgor may reasonably request for the purpose of
enabling the Pledgor to exercise the voting and/or consensual rights and powers
which Pledgor is entitled to exercise pursuant to clause (i) above and/or to
receive the dividends which Pledgor is authorized to retain pursuant to clause
(ii) above.





                                      K-4
<PAGE>   126

         (b)     Upon the occurrence and during the continuation of an Event of
Default, all rights of the Pledgor to exercise the voting and/or consensual
rights and powers which Pledgor is entitled to exercise pursuant to subsection
(a)(i) above and/or to receive the dividends which Pledgor is authorized to
receive and retain pursuant to subsection (a)(ii) above shall cease, and all
such rights thereupon shall become immediately vested in the Pledgee, which
shall have, to the extent permitted by law, the sole and exclusive right and
authority to exercise such voting and/or consensual rights and powers which the
Pledgor shall otherwise be entitled to exercise pursuant to subsection (a)(i)
above and/or to receive and retain the dividends which the Pledgor shall
otherwise be authorized to retain pursuant to subsection (a)(ii) above.  Any
and all money and other property paid over to or received by the Pledgee
pursuant to the provisions of this subsection (b) shall be retained by the
Pledgee as additional collateral hereunder and shall be applied in accordance
with the provisions of Section 10.  If the Pledgor shall receive any dividends
or other property which it is not entitled to receive under this Section, the
Pledgor shall hold the same in trust for the Pledgee, without commingling the
same with other funds or property of or held by the Pledgor, and shall promptly
deliver the same to the Pledgee upon receipt by the Pledgor in the identical
form received, together with any necessary endorsements.

         SECTION 8.  EVENT OF DEFAULT DEFINED.  For purposes of this Pledge
Agreement, "Event of Default" shall mean:

         (a)     The Pledgor shall fail to observe or perform any covenant or
agreement contained in Sections 4(a), 5, or 7(b) hereof;

         (b)     The Pledgor shall fail to observe or perform any covenant or
agreement contained in this Pledge Agreement (other than those covered by the
immediately preceding clause (a)) for a period of 30 days after written notice
thereof has been given to the Pledgor by the Pledgee; and

         (c)     an Event of Default under and as defined in the [Credit
Agreement][Guaranty] shall occur.

         SECTION 9.  REMEDIES UPON DEFAULT.

         (a)     In addition to any right or remedy that the Pledgee may have
under the Credit Agreement, the other Loan Documents or otherwise under
Applicable Law, if an Event of Default shall have occurred and be continuing,
the Pledgee may exercise any and all the rights and remedies of a secured party
under the Uniform Commercial Code as in effect in any applicable jurisdiction
(the "Code") and may otherwise sell, assign, transfer, endorse and deliver the
whole or, from time to time, any part of the Pledged Collateral at a public or
private sale or on any securities exchange, for cash, upon credit or for other
property, for immediate or future delivery, and for such price or prices and on
such terms as the Pledgee in its discretion shall deem appropriate.  The
Pledgee shall be authorized at any sale (if it deems it advisable to do so) to
restrict the prospective bidders or purchasers to Persons who will represent
and agree that they are purchasing the Pledged Collateral for their own account
in compliance with the Securities Act and upon consummation of any such sale
the Pledgee shall have the right to assign, transfer, endorse and deliver to
the purchaser or purchasers thereof the Pledged Collateral so sold.  Each
purchaser at any sale of Pledged Collateral shall take and hold the property
sold absolutely free





                                      K-5
<PAGE>   127

from any claim or right on the part of the Pledgor, and the Pledgor hereby
waives (to the fullest extent permitted by Applicable Law) all rights of
redemption, stay and/or appraisal which the Pledgor now has or may at any time
in the future have under any Applicable Law now existing or hereafter enacted.
The Pledgor agrees that, to the extent notice of sale shall be required by
Applicable Law, at least ten days' prior written notice to the Pledgor 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.  Such notice, in case of public sale, shall state the
time and place for such sale, and, in the case of sale on a securities
exchange, shall state the exchange on which such sale is to be made and the day
on which the Pledged Collateral, or portion thereof, will first be offered for
sale at such exchange.  Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the Pledgee
may fix and shall state in the notice or publication (if any) of such sale.  At
any such sale, the Pledged Collateral, or portion thereof to be sold, may be
sold in one lot as an entirety or in separate parcels, as the Pledgee may
determine in its sole and absolute discretion.  The Pledgee shall not be
obligated to make any sale of the Pledged Collateral if it shall determine not
to do so regardless of the fact that notice of sale of the Pledged Collateral
may have been given.  The Pledgee may, without notice or publication, adjourn
any public or private sale or cause the same to be adjourned from time to time
by announcement at the time and place fixed for sale, and such sale may,
without further notice, be made at the time and place to which the same was so
adjourned.  In case the sale of all or any part of the Pledged Collateral is
made on credit or for future delivery, the Pledged Collateral so sold may be
retained by the Pledgee until the sale price is paid by the purchaser or
purchasers thereof, but the Pledgee shall not incur any liability to the
Pledgor in case any such purchaser or purchasers shall fail to take up and pay
for the Pledged Collateral so sold and, in case of any such failure, such
Pledged Collateral may be sold again upon like notice.  At any public sale made
pursuant to this Pledge Agreement, the Pledgee, to the extent permitted by
Applicable Law, may bid for or purchase, free from any right of redemption,
stay and/or appraisal on the part of the Pledgor (all said rights being also
hereby waived and released to the extent permitted by Applicable Law), any part
of or all the Pledged Collateral offered for sale and may make payment on
account thereof by using any claim then due and payable to the Pledgee from the
Pledgor as a credit against the purchase price, and the Pledgee may, upon
compliance with the terms of sale and to the extent permitted by Applicable
Law, hold, retain and dispose of such property without further accountability
to the Pledgor therefor.  For purposes hereof, a written agreement to purchase
all or any part of the Pledged Collateral shall be treated as a sale thereof;
the Pledgee shall be free to carry out such sale pursuant to such agreement and
the Pledgor shall not be entitled to the return of any Pledged Collateral
subject thereto, notwithstanding the fact that after the Pledgee shall have
entered into such an agreement all Events of Default may have been remedied or
the Secured Obligations may have been paid in full as herein provided.  The
Pledgor hereby waives any right to require any marshaling of assets and any
similar right.

         (b)     In addition to exercising the power of sale herein conferred
upon it, the Pledgee shall also have the option to proceed by suit or suits at
law or in equity to foreclose this Pledge Agreement and sell the Pledged
Collateral or any portion thereof pursuant to judgment or decree of a court or
courts having competent jurisdiction.





                                      K-6
<PAGE>   128

         (c)     The rights and remedies of the Pledgee under this Pledge
Agreement are cumulative and not exclusive of any rights or remedies which it
would otherwise have.

         SECTION 10.  APPLICATION OF PROCEEDS OF SALE AND CASH.  The proceeds
of any sale of the whole or any part of the Pledged Collateral, together with
any other moneys held by the Pledgee under the provisions of this Pledge
Agreement, shall be applied by the Pledgee in the following order:

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

         (b)     Second:  to the payment of the interest due upon any of the
Secured Obligations, in any order which the Pledgee may elect;

         (c)     Third:  to the payment of the principal due upon any of the
Secured Obligations in any order which the Pledgee may elect; and

         (d)     Fourth:  the balance (if any) of such proceeds shall be paid
to the Pledgor or to whomsoever may be legally entitled thereto.

The Pledgor shall remain liable and will pay, on demand, any deficiency
remaining in respect of the Secured Obligations.

         SECTION 11.  PLEDGEE APPOINTED ATTORNEY-IN-FACT.  The Pledgor hereby
constitutes and appoints the Pledgee as the attorney-in-fact of the Pledgor
upon the occurrence and during the continuation of an Event of Default with
full power of substitution either in the Pledgee's name or in the name of the
Pledgor to do any of the following: (a) to perform any obligation of the
Pledgor hereunder in the Pledgor's name or otherwise; (b) to ask for, demand,
sue for, collect, receive, receipt and give acquittance for any and all moneys
due or to become due under and by virtue of any Pledged Collateral; (c) to
prepare, execute, file, record or deliver notices, assignments, financing
statements, continuation statements, applications for registration or like
papers to perfect, preserve or release the Pledgee's security interest in the
Pledged Collateral or any of the documents, instruments, certificates and
agreements described in Section 13(b); (d) to verify facts concerning the
Pledged Collateral in its own name or a fictitious name; (e) to endorse checks,
drafts, orders and other instruments for the payment of money payable to the
Pledgor, representing any interest or dividend or other distribution payable in
respect of the Pledged Collateral or any part thereof or on account thereof and
to give full discharge for the same; (f) to exercise all rights, powers and
remedies which the Pledgor would have, but for this Pledge Agreement, under the
Pledged Collateral; and (g) to carry out the provisions of this Pledge
Agreement and to take any action and execute any instrument which the Pledgee
may deem necessary or advisable to accomplish the purposes hereof, and to do
all acts and things and execute all documents in the name of the Pledgor or
otherwise, deemed by the Pledgee as necessary, proper and convenient in
connection with the preservation, perfection or enforcement of its rights
hereunder.  Nothing herein contained shall be construed as requiring or
obligating the Pledgee to make any commitment or to make any inquiry as to the
nature or sufficiency of any





                                      K-7
<PAGE>   129

payment received by it, or to present or file any claim or notice, or to take
any action with respect to the Pledged Collateral or any part thereof or the
moneys due or to become due in respect thereof or any property covered thereby,
and no action taken by the Pledgee or omitted to be taken with respect to the
Pledged Collateral or any part thereof shall give rise to any defense,
counterclaim or offset in favor of the Pledgor or to any claim or action
against the Pledgee.  The power of attorney granted herein is irrevocable and
coupled with an interest.

         SECTION 12.  REIMBURSEMENT OF PLEDGEE.  The Pledgor agrees to pay upon
demand to the Pledgee the amount of any and all reasonable expenses, including
the reasonable fees disbursements and other charges of its counsel and of any
experts or agents, and its fully allocated internal costs, that the Pledgee may
incur in connection with (i) the administration of this Pledge Agreement, (ii)
the custody or preservation of, or any sale of, collection from, or other
realization upon, any of the Pledged Collateral, (iii) the exercise or
enforcement of any of the rights of the Pledgee hereunder, or (iv) the failure
by the Pledgor to perform or observe any of the provisions hereof.  Any such
amounts payable as provided hereunder shall be additional obligations secured
hereby and by the other Security Documents.

         SECTION 13.  FURTHER ASSURANCES.  The Pledgor shall, at its sole cost
and expense, take all action that may be necessary or desirable in the
Pledgee's sole but reasonable discretion, so as at all times to maintain the
validity, perfection, enforceability and priority of the Pledgee's security
interest in the Pledged Collateral, or to enable the Pledgee to exercise or
enforce its rights hereunder, including without limitation (a) delivering to
the Pledgee, endorsed or accompanied by such instruments of assignment as the
Pledgee may specify, any and all chattel paper, instruments, letters of credit
and all other advices of guaranty and documents evidencing or forming a part of
the Pledged Collateral and (b) executing and delivering financing statements,
pledges, designations, notices and assignments, in each case in form and
substance satisfactory to the Pledgee, relating to the creation, validity,
perfection, priority or continuation of the security interest granted
hereunder.  The Pledgor agrees to take, and authorizes the Pledgee to take on
the Pledgor's behalf, any or all of the following actions with respect to any
Pledged Collateral as the Pledgee shall deem necessary to perfect the security
interest and pledge created hereby or to enable the Pledgee to enforce its
rights and remedies hereunder: (i) to register on the books of the Issuer in
the name of the Pledgee any Pledged Collateral in certificated or
uncertificated form; (ii) to endorse in the name of the Pledgee any Pledged
Collateral issued in certificated form; and (iii) by book entry or otherwise,
identify as belonging to the Pledgee a quantity of securities that constitutes
all or part of the Pledged Collateral registered in the name of the Pledgee.
Notwithstanding the foregoing the Pledgor agrees that Pledged Collateral which
is not in certificated form or is otherwise in book-entry form shall be held
for the account of the Pledgee.  The Pledgor hereby authorizes the Pledgee to
execute and file in all necessary and appropriate jurisdictions (as determined
by the Pledgee) one or more financing or continuation statements (or any other
document or instrument referred to in the immediately preceding clause (b)) in
the name of the Pledgor and to sign the Pledgor's name thereto.  The Pledgor
authorizes the Pledgee to file any such financing statement, document or
instrument without the signature of the Pledgor to the extent permitted by
applicable law.  To the extent permitted by Applicable Law, a carbon,
photographic, xerographic or other reproduction of this Pledge Agreement or any
financing statement is sufficient as a financing statement.  Any property
comprising part of the Pledged Collateral required to be delivered to the
Pledgee pursuant to this Pledge Agreement shall be

<PAGE>   130

accompanied by proper instruments of assignment duly executed by the Pledgor
and by such other instruments or documents as the Pledgee may reasonably
request.  In the event any Pledged Collateral in certificated form becomes
eligible for book-entry treatment, the Pledgor will use its best efforts to
effectuate such book-entry treatment with respect to such Pledged Collateral.

         SECTION 14.  SECURITIES ACT.  In view of the position of the Pledgor
in relation to the Pledged Collateral, or because of other current or future
circumstances, a question may arise under the Securities Act of 1933, as now or
hereafter in effect, or any similar Applicable Law hereafter enacted analogous
in purpose or effect (such Act and any such similar Applicable Law as from time
to time in effect being called the "Federal Securities Laws") with respect to
any disposition of the Pledged Collateral permitted hereunder.  The Pledgor
understands that compliance with the Federal Securities Laws might very
strictly limit the course of conduct of the Pledgee if the Pledgee were to
attempt to dispose of all or any part of the Pledged Collateral in accordance
with the terms hereof, and might also limit the extent to which or the manner
in which any subsequent transferee of any Pledged Collateral could dispose of
the same.  Similarly, there may be other legal restrictions or limitations
affecting the Pledgee in any attempt to dispose of all or part of the Pledged
Collateral in accordance with the terms hereof under applicable Blue Sky or
other state securities laws or similar Applicable Law analogous in purpose or
effect.  The Pledgor recognizes that in light of the foregoing restrictions and
limitations the Pledgee may, with respect to any sale of the Pledged
Collateral, limit the purchasers to those who will agree, among other things,
to acquire such Pledged Collateral for their own account, for investment, and
not with a view to the distribution or resale thereof.  The Pledgor
acknowledges and agrees that in light of the foregoing restrictions and
limitations, the Pledgee, in its sole and absolute discretion, may, in
accordance with Applicable Law, (a) proceed to make such a sale whether or not
a registration statement for the purpose of registering such Pledged Collateral
or part thereof shall have been filed under the Federal Securities Laws and (b)
approach and negotiate with a single potential purchaser to effect such sale.
The Pledgor acknowledges and agrees that any such sale might result in prices
and other terms less favorable to the seller than if such sale were a public
sale without such restrictions.  In the event of any such sale, the Pledgee
shall incur no responsibility or liability for selling all or any part of the
Pledged Collateral in accordance with the terms hereof at a price that the
Pledgee, in its sole and absolute discretion, may in good faith deem reasonable
under the circumstances, notwithstanding the possibility that a substantially
higher price might have been realized if the sale were deferred until after
registration as aforesaid or if more than a single purchaser were approached.
The provisions of this Section will apply notwithstanding the existence of
public or private market upon which the quotations or sales prices may exceed
substantially the price at which the Pledgee sells.

         SECTION 15.  INDEMNIFICATION.  The Pledgor agrees to indemnify and
hold the Pledgee and any corporation controlling, controlled by, or under
common control with, the Pledgee and any officer, attorney, director,
shareholder, agent or employee of the Pledgee or any such corporation (each an
"Indemnified Person"), harmless from and against any claim, loss, damage,
action, cause of action, liability, cost and expense or suit of any kind or
nature whatsoever (collectively, "Losses"), brought against or incurred by an
Indemnified Person, in any manner arising out of or, directly or indirectly,
related to or connected with this Pledge Agreement, including without
limitation, the exercise by the Pledgee of any of its rights and remedies under
this Pledge Agreement or any other action taken by the Pledgee pursuant to the
terms of this Pledge Agreement; provided, however, the Pledgor shall not be
liable to an Indemnified Person for any Losses to the extent that such Losses
result from the gross negligence or willful misconduct of such Indemnified
Person.  The Pledgor's obligations under this section shall survive the
termination of this Pledge Agreement and the payment in full of the Secured
Obligations.

         SECTION 16.  CONTINUING SECURITY INTEREST.  This Agreement shall
create a continuing security interest in the Pledged Collateral and shall
remain in full force and effect until it terminates in accordance with its
terms.  The Pledgor and the Pledgee hereby agree that the security interest
created by this Pledge Agreement in the Pledged Collateral shall not terminate
and shall continue and remain in full force and effect notwithstanding the
transfer to the Pledgor or any person designated by it of all or any portion of
the Pledged Collateral.

         SECTION 17.  NO WAIVER.  Neither the failure on the part of the
Pledgee to exercise, nor the delay on its part in exercising any right, power
or remedy hereunder, nor any course of dealing between the Pledgee and the
Pledgor shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power, or remedy hereunder preclude any other or
the further exercise thereof or the exercise of any other right, power or 
remedy.

         SECTION 18.  NOTICES.  Notices, requests and other communications
required or permitted hereunder shall be given in accordance with the
applicable terms of the [Credit Agreement][Guaranty] (or at such other address
a party may specify to the other party by like notice.  All such notices and
other communications shall be effective (i) if mailed, when received; (ii) if
telecopied, when transmitted; or (iii) if hand delivered, when delivered.

         SECTION 19.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA.

         SECTION 20.  AMENDMENTS.  No amendment or waiver of any provision of
this Pledge Agreement nor consent to any departure by the Pledgor 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.

                 (ii)     Obtaining landlords', mortgagees', mechanics',

         waivers with respect to any or all of the Collateral, in form and
         substance reasonably satisfactory to the Lender;

                 (iii)    Delivering to the Lender, endorsed or accompanied by
         such instruments of assignment as the Lender may specify, any and all
         chattel paper, instruments, letters of credit and all other advices of

                 (iv)     At the request of the Lender, marking conspicuously
         each document included in the Collateral and marking all chattel paper

         Applicable Law.

         (c)     The Lender is hereby authorized to execute and file in all
necessary and appropriate jurisdictions (as determined by the Lender) one or
more financing or continuation statements (or any other document or instrument
referred to in Section 3(b)(v) above) in the name of the Debtor and to sign the
Debtor's name thereto.  The Debtor authorizes the Lender to file any such
financing statement, document or instrument without the signature of the Debtor
to the extent permitted by Applicable Law.  Further, to the extent permitted by
Applicable Law, a carbon, photographic, xerographic or other reproduction of
this Security Agreement or of any Financing Statement is sufficient as a

         (d)     The Debtor shall mark its books and records 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 COLLATERAL GENERALLY.

         (a)     Verification.  The Lender shall have the right at any time and
from time to time, in its name in the name of the Debtor, to verify the
validity, amount or any other matter relating to any Receivables 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 Debtor will immediately thereafter deliver such instrument to
the Lender, appropriately endorsed to the Lender.

         (c)     Defense of Title.  The Debtor 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 in, the Collateral
against the claims and demands of all Persons.

         (d)     Maintenance of Collateral.  The Debtor 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 Debtor shall at all times maintain insurance
on its inventory and equipment against loss or damage by fire, theft, burglary,
pilferage, loss in transit and such other hazards and risks as the Lender shall
reasonably specify, under policies issued by the Debtor's present insurers or
other insurers acceptable to the Lender and in such amounts as is customarily
maintained by similar businesses, as may be required by Applicable Law or as
may be satisfactory to the Lender.  All premiums on such insurance shall be
paid by the Debtor and certified copies of the policies, or other evidence of
insurance acceptable to the Lender, shall be delivered to the Lender promptly
upon the Lender's request.  The Debtor will not use or permit the Collateral to
be used unlawfully or outside of any insurance coverage.  All insurance
policies required under this Section shall contain loss payable clauses on New
York standard loss payee forms or other forms satisfactory to the Lender,
naming the Lender as loss payee, and providing that:

                 (i)      All proceeds thereunder shall be payable directly to
         the Lender as its interest may appear;

                 (ii)     No such insurance shall be affected by any act or
         neglect of the insured or owner of the property described in such
         policy;

                 (iii)    Such policies and loss payable clauses may not be
         canceled, amended or terminated with respect to the Lender unless at
         least thirty days' prior written notice is given to the Lender; and





                                      L-5
<PAGE>   141

                 (iv)     There shall be no recourse against the Lender for
         payment of premiums or other amounts with respect thereto.

Any proceeds of insurance referred to in this Section shall be applied in
accordance with Section 9 hereof.

         (f)     Location of Office.  The Debtor's chief executive office,
principal place of business, and its books and records relating to the
Collateral will continue to be kept at the address set forth in the first
paragraph of this Security Agreement and the Debtor will not change the
location of such office and place of business or such books and records without
giving the Lender thirty days' prior written notice thereof.

         (g)     Change of Name, Structure, Etc.  Without giving the Lender
thirty days' prior written notice, the Debtor will not (i) change its name,
identity or structure (ii) conduct business under any trade name or other
fictitious name other than those set forth on Schedule 2(a), as modified from
time to time.

         (h)     Records Relating to Collateral.  The Debtor will at all times
keep complete and accurate records of all other Collateral.

         (i)     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 the Debtor, at any time or times during normal
business hours: (i) to inspect all files relating to the Collateral and the
premises upon which any information relating to the Collateral is located, (ii)
to discuss the Debtor'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.

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

         (k)     Payments Directly to Lender.  The Lender may at any time and
from time to time after the occurrence and continuation of a Default or Event
of Default notify, or request the Debtor to notify, in writing or otherwise,
any account debtor or other obligor with respect to any one or more of the
Receivables 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 Debtor, the Debtor 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 Debtor, and shall promptly deliver
the same to the Lender or any such agent or designee immediately upon receipt
by the Debtor in the identical form received, together with any necessary
endorsements.

         (l)     Sale of Collateral.  Except as permitted under the terms of
the Credit Agreement, the Debtor shall not sell, transfer, convey or dispose of
any Collateral outside the ordinary course of its business.  The inclusion of
"proceeds" of the Collateral under the Security Interest shall not





                                      L-6
<PAGE>   142

be deemed a consent by the Lender to any other sale or other disposition of any
part or all of the Collateral.

         (m)     Proceeds of Collateral.  The Debtor shall account fully and
faithfully for, and upon the Lender's request during the continuance of an
Event of Default, 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 Debtor shall at all times keep the Collateral and
proceeds thereof separate and distinct from other property of the Debtor and
shall keep accurate and complete records of the Collateral and proceeds thereof.

         SECTION 5.  THE LENDER APPOINTED ATTORNEY-IN-FACT.  The Debtor hereby
irrevocably appoints the Lender the Debtor's attorney-in-fact, with full
authority in the place and stead of the Debtor and in the name of the Debtor or
otherwise, from time to time upon the occurrence and during the continuance of
a Default or Event of Default 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 Security Agreement and to exercise
any rights and remedies the Lender may have under this Security 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 any Receivable; (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 Receivable
upon such terms, for such amount and at such time or times as the Lender deems
advisable, to settle, adjust, compromise, extend or renew any Receivable or to
discharge and release any Receivable; 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 6.  THE LENDER MAY PERFORM.  If the Debtor fails to perform
any agreement contained herein, the Lender may, with notice to the Debtor,
itself perform, or cause performance of, such agreement, and the reasonable
expenses of the Lender incurred in connection therewith shall be payable by the
Debtor under Section 12 hereof; provided, however, the Lender's failure to give
such notice shall not in any way affect the validity of any action taken by the
Lender under this Section.

         SECTION 7.  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





                                      L-7
<PAGE>   143

connection therewith shall be for the sole account of the Debtor and shall be
added to the Obligations.

         SECTION 8.  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)     Use of Premises and Patents.  The Lender may:

                 (i)      without notice, demand or other process, and without
         payment of any rent or any other charge enter any of the Debtor'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 Debtor's equipment;
         and

                 (ii)     in the exercise of the rights of the Lender under
         this Security 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 the Debtor therein, and the Debtor hereby grants a license
         to the Lender for this purpose.

         (b)     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 Debtor agrees that,
to the extent notice of sale shall be required by law, at least ten days'
notice to the Debtor 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.

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

         (d)     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/or the business operations of the Debtor and to exercise
such power as the court shall confer upon such receiver.





                                      L-8
<PAGE>   144

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

         SECTION 9.  APPLICATION OF PROCEEDS.  All proceeds from each sale of,
or other realization upon, all or any part of the Collateral following the
occurrence and continuation of an Event of Default, and all insurance proceeds
payable following the occurrence and continuation of an Event of Default 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 reasonable costs and expenses
actually incurred in connection with such sale or other realization, including
reasonable attorneys' fees actually incurred 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 any of
the Obligations in any order which the Lender may elect;

         (c)     Third:  to the payment of the outstanding principal of the
Obligations in any order which the Lender may elect; and

         (d)     Fourth:  the balance (if any) of such proceeds shall be paid
to the Debtor or to whomsoever may be legally entitled thereto.

The Debtor 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 Post-Default Rate then payable hereunder on such
Obligations, which interest shall constitute part of the Obligations.  So long
as no Event of Default shall have occurred and be continuing, the Debtor may
receive any insurance proceeds payable by reason of any damage or destruction
of any of the Collateral.  If the Lender shall receive any such insurance
proceeds which it is not otherwise entitled to retain, the Lender shall
promptly turn over such proceeds to the Debtor or to whomsoever may be legally
entitled thereto.

         SECTION 10.  RIGHTS CUMULATIVE.  The rights and remedies of the Lender
under this Security Agreement, the Credit Agreement and each other document or
instrument evidencing or securing the Obligations 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 11.  EXPENSES.  The Debtor will pay, within 10 days of
demand, all reasonable fees and expenses actually incurred by the Lender in
connection with (a) the collection or enforcement of the Obligations including
the reasonable fees and disbursements of counsel to the





                                      L-9
<PAGE>   145

Lender actually incurred by the Lender and (b) the exercise by the Lender of
any right or remedy granted to it under this Agreement if such exercise is done
by, through or with the assistance of an attorney.

         SECTION 12.  AMENDMENTS, ETC.  No amendment or waiver of any provision
of this Security Agreement nor consent to any departure by the Debtor 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.

         SECTION 13.  NOTICES.  Unless otherwise provided herein,
communications provided for hereunder shall be in writing and shall be mailed,
telecopied or delivered, in accordance with the notice provision set forth in
the [Credit Agreement][Guaranty].

         SECTION 14.  CONTINUING SECURITY INTEREST.  This Security 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 Debtor, its successors and assigns and
(iii) inure the benefit of the Lender, and its successors and assigns.  The
Debtor's successors and assigns shall include, without limitation, a receiver,
trustee or debtor-in-possession thereof or therefore.

         SECTION 15.  APPLICABLE LAW; SEVERABILITY.  THIS SECURITY AGREEMENT
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE
OF GEORGIA.  Whenever possible, each provision of this Security Agreement shall
be interpreted in such a manner as to be effective and valid under Applicable
Law, but if any provision of this Security 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 Security Agreement.  The
Secured Party may assign, transfer or sell any of the Obligations, or grant or
sell participation interests in any of the Obligations, to any Person pursuant
to the terms of the Credit Agreement.

         SECTION 16.  ARBITRATION.

         ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES HERETO INCLUDING
BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS SECURITY AGREEMENT
OR ANY OTHER LOAN DOCUMENT, INCLUDING ANY CLAIM BASED ON OR 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

JUDICIAL ARBITRATION AND MEDIATION SERVICES, INC. (J.A.M.S.) OR THE COMMERCIAL
ARBITRATION RULES OF THE AMERICAN ARBITRATION ASSOCIATION, AS APPLICABLE, AND
THE "SPECIAL RULES" SET FORTH BELOW.  IN THE EVENT OF ANY INCONSISTENCY, THE

STATUTES OF LIMITATION OR REPOSE AND ANY WAIVERS CONTAINED IN THIS SECURITY
AGREEMENT; OR (II) BE A WAIVER BY THE LENDER OF THE PROTECTION AFFORDED TO IT
BY 12 U.S.C. SEC. 91 OR ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR (III) LIMIT
THE RIGHT OF THE LENDER HERETO (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT

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 SECURITY AGREEMENT.  NEITHER THE 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.

         SECTION 17.  INDEMNIFICATION.  The Debtor 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 Debtor's business, any action taken by the Lender with respect

however, that the Debtor shall not be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Lender's gross
negligence or willful misconduct.  Without limiting the generality of the
foregoing, the Debtor agrees to reimburse the





                                      L-11
<PAGE>   147

Lender promptly upon demand for any reasonable out-of-pocket expenses
(including reasonable 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 Security Agreement, any suit or
action brought by the Lender to enforce the terms of this Security Agreement,
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.  The agreements in this Section shall survive the termination
of this Security Agreement.  The Lender agrees to give the Debtor prompt notice
of any suit or cause of action brought against the Lender which is covered by
