    There currently exists wide disparity in the methods of recording revenue in
the physician practice management (PPM) industry. The Company believes the
following unaudited supplemental information, which includes patient service
revenue of both owned as well as managed practices ("system wide" revenue)
allows a reader of the Company's financial statements to evaluate comparability
with other PPM companies recording patient services revenue on a consolidated
basis for financial reporting purposes. The unaudited supplemental "system wide"
information is being presented for supplemental purposes only and should be read
in conjunction with the Company's financial statements.

NOTE 6.  INTANGIBLE ASSETS
    The Company's physician practice acquisitions involve the purchase of
tangible and intangible assets and the assumption of certain liabilities of the
acquired practices. As part of the purchase price allocation, the Company
allocates the purchase price to the tangible and identifiable intangible assets
acquired and liabilities assumed based on estimated fair market values. Costs of
acquisitions in excess of the net estimated fair value of tangible and
identifiable intangible assets acquired and liabilities assumed are amortized
using the straight line method over a period of 25 years. At September 30, 1998,
the amount of such intangible assets was approximately $24,907,000, with
accumulated amortization totaling approximately $770,000.

NOTE 7.  NEW ACCOUNTING PRONOUNCEMENTS

    In June 1997, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income." SFAS No. 130 is designed to improve the reporting of
changes in equity from period to period. SFAS No. 130 is effective for fiscal
years beginning after December 15, 1997. The adoption of SFAS No. 130 for fiscal
1998 was not material to the Company's financial statements.

    In March 1998, the Emerging Issues Task Force of the FASB issued its
Consensus on Issue 97-2 ("EITF 97-2"). EITF 97-2 addresses certain specific
matters pertaining to the physician practice management industry. EITF 97-2
would be effective for the Company for its year ending December 31, 1998. EITF
97-2 addresses the ability of physician practice management companies to
consolidate the results of physician practices with which it has an existing
contractual relationship. The Company is in the process of analyzing the effect
of all its contractual relationships but currently believes that certain
contracts would meet the criteria of EITF 97-2 for consolidating the results of
operations of the related physician practices, which would require the Company
to restate its prior period financial statements to conform to such
consideration. The Company anticipates incorporating the provisions of EITF97-2
effective for its year ending December 31, 1998. EITF 97-2 also has addressed
the accounting method for future combinations with individual physician
practices. The Company believes that, based on the criteria set forth in EITF
97-2, virtually all of its future acquisitions of individual physician practices
will continue to be accounted for under the purchase method of accounting.

NOTE 8.  EARNINGS PER SHARE

      The Company has calculated its basic and diluted earnings per share in
accordance with SFAS No. 128, "Earnings Per Share". Basic earnings per share are
calculated by dividing net income available to common stockholders by the
weighted average number of common shares outstanding for the periods presented.
Diluted earnings per share reflects the potential dilution that could occur if
securities and other contracts to issue common stock where exercised or
converted into common stock or resulted in the issuance of common stock that
then shared in the earnings of the entity.

      A reconciliation of the number of weighted average shares used in
calculating basic and diluted earnings per share is as follows:

NOTE 9.  CREDIT AGREEMENT


    On July 31, 1998, the Company closed on a four year $45 million amended and
restated senior credit facility syndicated by Nationsbanc Montgomery Securities
LLC. Syndicate lenders include NationsBank, N.A., PNC Bank and Rabobank
Nederland (the "Credit Facility"). The Credit Facility replaced the Company's
$20 million senior credit facility. Borrowings under the Credit Facility (i) are
secured by the assignment to the banks of the Company's stock in all of its
subsidiaries and the Company's accounts receivable, including the accounts
receivable assigned to the Company by affiliated practices pursuant to
management services agreements, (ii) are guaranteed by all subsidiaries
(including future subsidiaries) and (iii) restrict the Company from pledging its
assets to any other party. Advances under the Credit Facility will be used to
fund acquisitions and working capital, will be governed by a borrowing base
related primarily to the Company's earnings before interest, taxes, depreciation
and amortization ("EBITDA") and will bear interest, at the Company's option,
based upon either a prime-based or LIBOR-based rate. EBITDA is used by the
Company as an indicator of a company's ability to incur and service debt. EBITDA
should not be considered an alternative to operating income, net income, cash
flows or any other measure of performance as determined in accordance with
generally accepted accounting principles, as an indicator of operating
performance, or as a measure of liquidity. The Credit Facility contains
affirmative and negative covenants which, among other things, require the
company to maintain certain financial ratios (including maximum indebtedness to
pro forma EBITDA, maximum indebtedness to capital, minimum net worth, minimum
current ratio and minimum fixed charges coverage), limit the amounts of
additional indebtedness, dividends, advances to officers, shareholders and
physicians, acquisitions, investments and advances to subsidiaries, and restrict
changes in management and the Company's business. As of November 13, 1998, the
Company had approximately $3.7 million of borrowings under the Credit Facility.

NOTE 10.  SUBSEQUENT EVENTS

    On October 12, 1998, pursuant to an asset acquisition agreement, the Company
completed the acquisition of the assets of Cleveland Ear, Nose and Throat
Center, Inc. ("Cleveland ENT"), a ten physician ENT physician practice with
eight allied health care professionals and eight clinical offices in
metropolitan Cleveland, Ohio. Cleveland ENT had previously been affiliated with
MedPartners, Inc. ("MedPartners"). In connection with the transaction, the
Company entered into an amended and restated Clinic

<PAGE>   11


Services Agreement with Cleveland ENT maintaining the percentage of net income
management fee structure which existed in the MedPartners/Cleveland ENT Clinic
Services Agreement. The Company is discussing modifying the percentage of net
income arrangement consistent with the Company's historical practices. In
connection therewith, the Company has granted Cleveland ENT a one time option,
which expires on December 15, 1998, to unwind the transaction with the Company
as of December 31, 1998 and repurchase all Cleveland ENT non-medical assets
acquired by the Company for a total cash purchase price equal to the price paid
by the Company to MedPartners for such assets, plus amounts invested by the
Company in Cleveland ENT.


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

    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; risks associated with combined operations; and risks
relating to acquisitions and managing growth; dependence on affiliated
physicians; dependence on managed care organizations; risks associated with
capitated arrangements, including potential reductions in reimbursement;
competition; regulatory risks; risks relating to credit facility and substantial
leverage; and other risks.

GENERAL

    The Company is a physician practice management company which provides
comprehensive management services to physician practices specializing in the
treatment and management of ENT diseases and disorders, including specialists
practicing in the fields of allergy, audiology, oral surgery, plastic surgery
and sleep medicine. In March 1997, simultaneously with the closing of the
Company's IPO, the Company effected the Reorganization in which the Company
acquired all of the common stock of the ENT Networks and substantially all of
the assets of the Initial Practices. Since the consummation of the
Reorganization through November 3, 1998, the Company has acquired substantially
all of the assets of (i) four ENT physician practices with ten physicians in the
metropolitan Atlanta area, (ii) one ENT physician practice with two physicians
in North Georgia, (iii) one ENT physician practice with four physicians in the
metropolitan Chicago area, (iv) four ENT physician practices with five
physicians in South Florida, and (v) one ENT physician practice with ten
physicians in the metropolitan Cleveland, Ohio area. In addition, the Company
has acquired (i) the stock and related assets of six professional associations
comprising one ENT physician practice group with seven physicians in South
Florida, and (ii) the stock and related assets of three corporations that are
successors to three ENT physician practices employing an aggregate of 20
physicians in Southern New York and Northern New Jersey. The Company also
acquired substantially all of the tangible assets of Physicians' Domain, a White
Plains, New York based ENT physician practice management company and a 17.5%
equity interest in 3 ambulatory surgery centers containing 14 operating rooms.
As a result of these acquisitions as of November 3, 1998, the Company was
affiliated with 81 physicians, one TMJ specialist and 79 allied health care
professionals with 66 clinical offices in Alabama, Florida, Georgia, Illinois,
New York, New Jersey and Ohio.

    The Company's revenue is derived (i) under management services agreements
with affiliated practices; (ii) from capitated managed care contracts held by
the ENT Networks, wholly-owned subsidiaries of the Company; (iii) from patient
service revenue generated by the Company's wholly owned subsidiary, ENT &
Allergy Associates, which directly employs physicians in Birmingham, Alabama;
and (iv) from earnings from the Company's unconsolidated subsidiary determined
on the equity basis of accounting.

    Management fees consist of either a stipulated percentage of revenue
generated by or on behalf of physicians practicing at (non-owned) affiliated
practices, a fixed dollar amount of management fee or a stipulated percentage of
practice income before physician compensation, along with reimbursement of
Practice Expenses (as defined). Capitation revenue consists of fixed monthly
payments received by the Company directly from health maintenance organizations
("HMOs") (or payors subcontracting with HMOs) or third party payors. Patient
service revenue consists of gross charges, less allowances for bad debts and
contractual adjustments, generated by or on behalf of physicians practicing at
the Company's wholly-owned subsidiary, ENT & Allergy Associates.

    Operating expenses consist of (i) provider claims, wages and benefits, (ii)
general and administrative expenses and (iii) depreciation and amortization.
Provider claims include claims paid or incurred in connection with medical
surgical services provided to managed care enrollees covered under the Company's
capitated managed care agreements. Wages and benefits include all salary and
benefit costs associated with corporate and clinic level personnel. General and
administrative expenses include all other corporate and clinic level operating
expenses, including real and personal property rent, medical and office
supplies, utilities and professional




                                      -11-
<PAGE>   12


fees. Depreciation and amortization expense includes non-cash charges related to
corporate and clinic level equipment depreciation, along with amortization of
intangible assets, including the costs of acquisitions in excess of the fair
value of tangible and identifiable intangible assets acquired. Depreciation is
computed utilizing the straight-line method over lives ranging from three to
seven years, while intangible assets are amortized utilizing the straight-line
method primarily over a period of 25 years.

    The Company's relationships with its affiliated physicians are set forth in
various asset acquisition agreements and management services agreements. The
management services agreements, which have a term of 40 years, delineate the
responsibilities and obligations of the physician practices and the Company.
These agreements provide for the affiliated practices to assign to the Company
all of its non-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, 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, the Company retains as a
part of its management fee, a stipulated percentage (typically 12.5%) of all
revenues (after adjustment for contractual allowances) generated by or on behalf
of physicians practicing at such practice, a fixed dollar amount of management
fee or a stipulated percentage of practice income before physician compensation,
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. 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.

    The Company holds, manages and administers capitated managed care contracts
with Cigna HealthCare of Georgia, Inc. ("CIGNA"), United HealthCare of Georgia,
Inc. ("United"), and The Morgan Health Group, Inc. ("Morgan"), which require the
Company to contract for the provision of substantially all of the ENT medical
and surgical professional services required by the enrollees of these managed
care companies in the metropolitan Atlanta area. The Company has contracted with
associated physicians, including those at the Company's affiliated practices in
Atlanta and North Georgia, to provide substantially all of such medical
professional services in exchange for compensation on a discounted
fee-for-service basis. At September 30, 1998, the Company's three capitated
managed care contracts covered an aggregate of 347,390 enrollees.

    In September 1998, the Company entered into an exclusive specialty provider
contract with United HealthCare of Alabama, Inc. covering approximately 80,000
commercial and Medicare members of United HealthCare of Alabama, Inc., in the
Birmingham, Alabama, metropolitan area. United HealthCare of Alabama, Inc. will
pay Alabama ENT on a prepaid basis for the provision of such services.
Additionally, the contract provides for the expansion of the exclusive prepaid
arrangement into other United HealthCare of Alabama, Inc., markets throughout
Alabama. The contract, effective October 1, 1998, has an initial term of two (2)
years and automatically renews for successive one (1) year terms thereafter upon
the mutual agreement of the parties.

RESULTS OF OPERATIONS

      Comparisons of the nine month period ended September 30, 1998 with data
for the nine month period ended September 30, 1997 are not meaningful since the
Company did not commence business operations until the closing of the
reorganization and its IPO on March 26, 1997.

      Revenue. Management fees increased to $9,185,413 for the three months
ended September 30, 1998 as compared with $3,462,249 for the same period in
1997, an increase of $5,723,164 or 165%. The increase in management fees is
primarily attributable to an increase in the number of physicians affiliated
with the Company at September 30, 1998 to 82 as compared with 33 for the same
period in 1997 as a result of the Company's acquisitions since the
Reorganization. Capitation revenues increased to $1,208,506 for the three months
ended September 30, 1998 as compared with $1,135,825 for the same period in
1997, an increase of $72,681 or 6%. The increase in capitation revenues is
primarily attributable to an increase in the aggregate number of enrollees to
approximately 347,000 at September 30, 1998, an increase of approximately 6%.
Patient service revenues increased to $410,743 for the three months ended
September 30, 1998 as compared with $339,886 for the same period in 1997, an
increase of $70,907 or 20.1%. The increase in patient service revenues is
primarily attributable to an increase in the aggregate number of patient office
visits and surgeries performed during the three months period ended September
30, 1998 as compared with the same period in 1997.



                                      -12-
<PAGE>   13


      For the three month period ended September 30, 1998, the Company recorded
as revenue earnings from its 17.5% equity interest in Atlanta Surgery Center in
the amount of $267,440.

      On a supplemental basis, patient service revenue generated by physicians
who were affiliated with the Company for both periods ended September 30, 1997
and 1998 increased on average approximately 2% per physician.

      As a result of the foregoing factors, the Company's net revenue increased
to $11,072,152 for the three months ended September 30, 1998 as compared with
$4,937,960 for the same period in 1997, an increase of $6,134,192 or 124%.

      Provider claims, wages, and benefits. Provider claims, wages and benefits,
increased to $4,868,739 for the three months ended September 30, 1998 as
compared with $2,436,570 for the same period in 1997, an increase of $2,432,169
or 99%. The dollar increase in provider claims, wages and benefits was primarily
attributable to the addition of non-medical personnel at the Company's
affiliated practices required to support the increase in the number of
affiliated physician groups managed by the Company. As a percent of net revenue,
provider claims, wages and benefits decreased to 44% for the three months ended
September 30, 1998 as compared to 49% for the same period in 1997. This decrease
was primarily attributable to the increase in net revenue that was greater than
the incremental increase in wages and benefits.

      General and administrative. General and administrative expenses increased
to $3,376,666 for the three months ended September 30, 1998 as compared with
$1,409,034 for the same period in 1997, an increase of $1,967,632 or 140%. This
increase was primarily attributable to the addition of personnel and greater
support costs associated with the Company's rapid expansion since September 30,
1997. As a percent of net revenue, general and administrative expenses increased
to 30% for the three months ended September 30, 1998 as compared to 29% for the
same period in 1997, as a result of the foregoing factors.

      Depreciation and Amortization. Depreciation and amortization expenses
increased to $519,987 for the three months ended September 30, 1998 as compared
with $130,166 for the same period in 1997, an increase of $389,821 or 300%. This
increase was primarily the result of the increases in intangible assets
resulting from additional acquisitions and resulting increases in amortization
of intangible assets associated with the Company's affiliation with physician
groups, as well as investments in equipment, leasehold improvements and
management information systems. As a percent of net revenue, depreciation and
amortization expense increased to 5% for the three months ended September 30,
1998 as compared with 3% for the same period in 1997, as a result of the
foregoing factors.

      Other Income (expense). Other expense for the three months ended September
30, 1998 was $83,773 and is derived from interest income earned on the short
term investment of excess cash and cash equivalents which was offset by (i)
interest charges to affiliated practices for additions to clinical equipment,
leasehold improvements and other fixed assets and (ii) interest expense related
primarily to the subordinated seller notes and the commitment fee in conjunction
with the $45 million senior credit facility. Other income for the three months
ended September 30, 1997 was $126,877 and is derived from interest income earned
on the short term investment in cash and cash equivalents of the IPO proceeds,
net of amounts of immaterial interest expense.

      Income Taxes. Income taxes for the quarters ended September 30, 1998 and
1997 were provided for at 39% effective tax rate.

LIQUIDITY AND CAPITAL RESOURCES

      The Company utilizes capital primarily (i) to acquire assets or equity of
physician practices, (ii) to acquire equipment utilized by affiliated practices,
(iii) to fund corporate capital expenditures including management information
systems and (iv) to fund ongoing corporate working capital requirements.

      At September 30, 1998, the Company had working capital of $16,486,043,
compared to $10,469,429 at December 31, 1997, an increase of $6,016,614. The
increase in working capital was due primarily to an increase in net accounts
receivable of $6,003,601.

      For the nine month period ended September 30, 1998 net cash provided by
operating activities was $1,012,004 compared to net cash used in operating
activities of $718,690 for the same period in 1997. Net cash used in investing
activities for the nine months ended September 30, 1998 was $18,216,013 with
$16,577,826 expended as cash consideration for acquisitions. Net cash provided
by financing activities for the nine months ended September 30, 1998 was
$16,650,511 with $16,577,826 received pursuant to the Company's public offering
in May 1998, net of offering costs.



                                      -13-
<PAGE>   14



      During the three month period ended September 30, 1998, the Company
acquired substantially all of the assets (other than certain excluded assets
such as employment agreements and patient charts, records and files) and assumed
certain contractual liabilities of (i) Maliner, (ii) Leonard, and (iii) acquired
in the aggregate a 17.5% limited partnership interest in Atlanta Surgery Center.
In connection with the acquisition of assets of Maliner, Leonard and limited
partnership interest, the Company (i) paid an aggregate of $5,455,000 in cash,
(ii) issued an aggregate of 34,552 shares of Common Stock of the Company, (iii)
agreed to issue an aggregate of 34,552 shares of Common Stock of the Company and
(iv) issued a $150,000 non-interest bearing contingent promissory note which is
payable at the Company's option, in cash or the Company's Common Stock, upon the
holder achieving certain performance targets. In connection with these
transactions, the Company paid approximately $219,500 in fees to Premier
HealthCare, an affiliate of the Company's Vice Chairman and Secretary, for
advisory services rendered.

      On October 12, 1998, pursuant to an asset acquisition agreement, the
Company completed the acquisition of the assets of Cleveland ENT, a ten
physician ENT physician practice with eight allied health care professionals and
eight clinical offices in metropolitan Cleveland, Ohio. Cleveland ENT had
previously been affiliated with MedPartners. In connection with the transaction,
the Company entered into an amended and restated Clinic Services Agreement with
Cleveland ENT maintaining the percentage of net income management fee structure
which existed in the MedPartners/Cleveland ENT Clinic Services Agreement. The
Company is discussing modifying the percentage of net income arrangement
consistent with the Company's historical practices. In connection therewith, the
Company has granted Cleveland ENT a one time option, which expires on December
15, 1998, to unwind the transaction with the Company as of December 31, 1998 and
repurchase all Cleveland ENT non-medical assets acquired by the Company for a
total cash purchase price equal to the price paid by the Company to MedPartners
for such assets, plus amounts invested by the Company in Cleveland ENT. In
connection with this transaction, the Company borrowed approximately $3.7
million under the Company's Credit Facility and used a portion of the net
proceeds received from the Company's public offering in May 1998.

      Several multi-specialty companies in the physician practice management
("PPM") industry have recently announced that they will be discontinuing PPM
activities or will be divesting certain assets related to physician practice
management. The Company believes that as a result of this and other market
conditions, there has been and will continue to be a decrease in acquisition
activity in the PPM industry which will likely affect the Company. As a result,
the Company believes that it and other PPM companies may see a slow down in
revenue growth attributable to acquisitions. As previously announced, the
Company intends to focus its efforts on ancillary service development, practice
acquisitions in the Company's existing markets and enhancing the operations of
affiliated practices. The Company also intends to continue to pursue new market
acquisitions on a highly selective basis. There are additional factors, such as
health care and government regulation and general economic conditions which may
also affect the PPM industry. As a result of these and other conditions, there
can be no assurance that acquisition opportunities will be available to the
Company or that the Company will be able to consummate future acquisitions.


YEAR 2000

      The Year 2000 issue is the result of using only the last two digits to
indicate the year in computer hardware and software programs and embedded
technology such as micro-controllers. As a result, these programs do not
properly recognize a year that begins with "20" instead of the familiar "19." If
uncorrected, such programs will be unable to interpret dates beyond the year
1999, which could cause computer system failure or miscalculations which could
disrupt the Company's operations and adversely affect its cash flows and results
of operations.
    
      The Company recognizes the importance of the Year 2000 issue and has given
it high priority. The Company's objective is to ensure an uninterrupted
transition to the year 2000 by assessing, testing and modifying products and
information technology ("IT") systems and non-IT systems so that such systems
and software will perform as intended and information and dates can be processed
with expected results ("Year 2000 Compliant"). The scope of the Company's
compliance efforts include (i) identifying and assessment of risks, including
the risks of non-compliance by third parties, (ii) development of remediation
and contingency plans, (iii) implementation and (iv) testing. The Company has
not yet determined the extent of contingency planning that may be required.

      There are three major IT system applications that the Company relies upon
to process transactions and provide information for managing its operations.
These applications have been identified as follows:

      -     Accounting and financial reporting system
      -     Practice management billing and accounts receivable systems
      -     Capitated claims processing and reporting system

      Accounting and financial reporting system - During 1998 the Company fully
implemented the Great Plains accounting and financial reporting software
applications at all of its affiliated practices, its subsidiaries and its
corporate locations. The Great Plains accounting package has been modified and
tested and is Year 2000 compliant.

      Practice management billing and accounts receivable systems - The
Company's affiliated practices currently utilize software packages which were
developed by large third party software development companies such as Medic,
Medical Manager, Verysis and Reynolds & Reynolds. The Company has been in
contact with all of these companies and believes that all
Year 2000 compliant modified programs will be fully tested and implemented by
the Company and its affiliates during the first quarter of 1999.

      Capitated claims processing and reporting system - The Company has
developed internally a capitated claims processing and reporting system which is
Year 2000 compliant.

      The Company is also highly dependent on receiving payments from third
party payors for capitated fees and for insurance reimbursement for claims
submitted by its affiliated practices, and as such, the ability of such payors
to process claims submitted by affiliated practices accurately and timely,
constitutes a significant risk to the Company's cash flow and could materially
adversely affect the Company's operations. The Company and its affiliated
practices have been or will be in communication with these payors to insure that
these payors will be Year 2000 Compliant and will be able to process claims
uninterrupted. However, there can be no assurance that such third party payors
will be Year 2000 Compliant.

      Like virtually every company, the Company is at risk for the failure of
major infrastructure providers to adequately address potential Year 2000
problems. The Company is highly dependent on a variety of public and private
infrastructure providers to conduct its business. Failures of banking systems,
basic utility providers, telecommunication providers and other services to
achieve Year 2000 compliance, could have a material adverse effect on the
ability of the Company and its affiliated practices to conduct business. While
the Company is aware of these risks, a complete assessment of all such risks is
beyond the scope of the Company's Year 2000 project or ability to address.

      Through September 30, 1998, the Company has incurred costs of
approximately $125,000 related to the Year 2000 issue. The Company does not
anticipate that it will incur any additional material costs associated with
addressing Year 2000 issues.

      The Company's current estimates of the amount of time and costs necessary
to remediate and test its computer systems are based on the facts and
circumstances existing at this time. The estimates were made using assumptions
of future events including the continued availability of certain resources, Year
2000 modification plans, implementation success by key third-parties, and other
factors. New developments may occur that could affect the Company's estimates of
the amount of time and costs needed to modify and test its IT and non-IT systems
for Year 2000 compliance. These developments include, but are not limited to:
(i) the availability and cost of personnel trained in this area; (ii) the
ability to locate and correct all relevant date-sensitive codes in both IT and
non-IT systems; (iii) unanticipated failures in its IT and non-IT systems; and
(iv) the planning and Year 2000 compliance success that third-parties attain.

      The Company cannot determine the impact of these potential developments on
the current estimate of probable costs of making its products and IT and non-IT
systems Year 2000 Compliant. Accordingly, the Company is not able to estimate
its possible future costs beyond the current estimates of costs. As new
developments occur, these cost estimates may be revised to reflect the impact
of these developments on the costs to the Company of making its products and IT
and non-IT systems Year 2000 Compliant. Such revisions in costs could have a
material adverse impact on the Company's results of operations in the quarterly
period in which they are recorded. Although the Company considers it unlikely,
such revisions could also have a material adverse effect on the business,
financial condition or results of operations of the Company.

Borrower in consideration for such Acquisition; (b) the aggregate amount of
Indebtedness acquired, incurred or assumed by the Borrower and its Subsidiaries

SECTION 2.9.  VOLUNTARY REDUCTIONS OF THE COMMITMENT.

         The Borrower shall have the right to terminate or reduce the aggregate
unused amount of the Commitments (for which purpose use of the Commitments shall

Borrower, during the period from the Effective Date to but excluding the

the aggregate outstanding principal amount of the Swingline Loans exceeds the
Swingline Commitment in effect at such time, the Borrower shall immediately pay
to the Agent for the account of Swingline Lender the amount of such excess.
Subject to the terms and conditions of this Agreement, the Borrower may borrow,
repay and reborrow Swingline Loans hereunder. Except as otherwise provided in
Section 2.9., the borrowing of a Swingline Loan shall not constitute usage of
any Lender's Commitment for purposes of calculation of the fee payable under
Section 3.6.(b) or otherwise.

         (b) Procedure for Borrowing Swingline Loans. With respect to any
Swingline Loan not being made to the Borrower as contemplated under subsection
(f) below, the Borrower shall give the Agent and Swingline Lender notice
pursuant to a Notice of Swingline Borrowing or otherwise given to the Agent and
Swingline Lender in such manner, and no later than such time, as may be agreed
to by the Borrower and the Swingline Lender in writing from time to time. Each
Swingline Loan, other than one deemed requested as contemplated by subsection
(f) below, shall be in the minimum amount of $100,000 and integral multiples of
$50,000 in excess thereof, or such other minimum amounts agreed to by the
Swingline Lender and the Borrower. Not later than such time as may be agreed to
by the Borrower and the Swingline Lender from time to time and subject to
satisfaction of the applicable conditions set forth in Article V. for such
borrowing, the Swingline Lender will make the proceeds of such Swingline Loan

account specified by the Borrower in the Notice of Swingline Borrowing or as
otherwise directed by the Borrower in writing.

rate equal to the Base Rate (as in effect from time to time) per annum or (ii)
at such other rate or rates as the Borrower and Swingline Lender may agree from
time to time in writing. Interest payable on Swingline Loans is solely for the
account of the Swingline Lender. All accrued and unpaid interest on Swingline
Loans shall be payable on the dates and in the manner provided in Section 2.2.
with respect to interest on Base Rate Loans (except as the Swingline Lender and
the Borrower may otherwise agree in writing in connection with any particular
Swingline Loan).

         (d) Swingline Note. The Swingline Loans shall, in addition to this
Agreement, be evidenced by the Swingline Note.



                                      -25-

         (e) Repayment and Participations of Swingline Loans. The Borrower
agrees to repay each Swingline Loan within one Business Day of demand therefor
by the Swingline Lender and in any event, within 10 Business Days after the date
such Swingline Loan was made. Notwithstanding the foregoing, the Borrower shall
repay the entire outstanding principal amount of, and all accrued but unpaid
interest on, the Swingline Loans on the Termination Date (or such earlier date
as the Swingline Lender and the Borrower may agree in writing). In lieu of
demanding repayment of any outstanding Swingline Loan from the Borrower, the
Swingline Lender may at any time, on behalf of the Borrower (which hereby
irrevocably directs the Swingline Lender to act on its behalf), request a
borrowing of Base Rate Loans from the Lenders in an amount equal to the
principal balance of such Swingline Loan. The Swingline Lender shall give notice
to the Agent of any such borrowing of Base Rate Loans not later than 11:00 a.m.
on the proposed date of such borrowing. Each Lender will make available to the
Agent for the account of the Swingline Lender, in immediately available funds,
the proceeds of the Loan to be made by such Lender. The Agent shall pay the
proceeds of such Loans to the Swingline Lender, which shall apply such proceeds
to repay such Swingline Loan. If Lenders are prohibited from making Loans
required to be made under this subsection for any reason whatsoever, including
without limitation, the occurrence of any of the Defaults or Events of Default
described in Sections 10.1.(e) or 10.1.(f), each Lender shall purchase from the
Swingline Lender, without recourse or warranty, an undivided interest and
participation to the extent of such Lender's Pro Rata Share of such Swingline
Loan, by directly purchasing a participation in such Swingline Loan in such
amount and paying the proceeds thereof to the Agent for the account of the
Swingline Lender in Dollars and in immediately available funds. A Lender's
obligation to purchase such a participation in a Swingline Loan shall be
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including without limitation, (i) any claim of setoff, counterclaim,
recoupment, defense or other right which such Lender or any other Person may
have or claim against the Agent, the Swingline Lender or any other Person
whatsoever, (ii) the occurrence or continuation of a Default or Event of Default
(including without limitation, any of the Defaults or Events of Default
described in Sections 10.1.(e) or (f)) or the termination of any Lender's
Commitment, (iii) the existence (or alleged existence) of an event of condition
which has had or could have a Material Adverse Effect, (iv) any breach of any
Loan Document by the Agent, any Lender or the Borrower or (v) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing. If such amount is not in fact made available to the Swingline
Lender by any Lender, the Swingline Lender shall be entitled to recover such
amount on demand from such Lender, together with accrued interest thereon for
each day from the date of demand thereof, at the Federal Funds Rate. If such
Lender does not pay such amount forthwith upon the Swingline Lender's demand
therefor, and until such time as such Lender makes the required payment, the
Swingline Lender shall be deemed to continue to have outstanding Swingline Loans
in the amount of such unpaid participation obligation for all purposes of the
Loan Documents (other than those provisions requiring the other Lenders to
purchase a participation therein). Further, such Lender shall be deemed to have
assigned any and all payments made of principal and interest on its Loans, and
any other amounts due to it hereunder, to the Swingline Lender to fund Swingline
Loans in the amount of the participation in Swingline Loans that such Lender
failed to purchase pursuant to this Section until such amount has been purchased
(as a result of such assignment or otherwise).

the Borrower a Swingline Loan in an amount equal to the amount by which drafts
against the Operating Account exceed the available balance of funds then on
deposit in the Operating Account. The Agent shall notify the Swingline Lender of
the amount of such excess. The Swingline Lender shall make the proceeds of each
such Swingline Loan available to the Borrower by paying the same to the Agent
for deposit into the Operating Account. At 5:00 p.m. on each Business Day, the
Borrower shall repay a principal amount of Swingline Loans by an amount equal to
the positive balance, if any, of available funds then on deposit in the
Operating Account as determined by the Agent at such time. The Borrower hereby
authorizes the Agent to deduct such amount from the Operating Account without
notice to the Borrower, and to pay such amount to the Swingline Lender in
repayment of the then outstanding principal balance of Swingline Loans. The
provisions of this subsection shall not become effective until the Borrower has
executed and delivered the Swingline Lender's customary documentation relating
to its "Auto Borrow" and "Auto Sweep" programs.

SECTION 2.11.  AMOUNT LIMITATIONS.

         Notwithstanding any other term of this Agreement or any other Loan
Document, at no time may the aggregate principal amount of all outstanding
Revolving Loans, together with the aggregate principal amount of all outstanding
Swingline Loans, exceed the aggregate amount of the Commitments.

              ARTICLE III. PAYMENTS, FEES AND OTHER GENERAL PROVISIONS

SECTION 3.1.   PAYMENTS.

         Except to the extent otherwise provided herein, all payments of
principal, interest and other amounts to be made by the Borrower under this
Agreement or any other Loan Document shall be made in Dollars, in immediately
available funds, without deduction, set-off or counterclaim, to the Agent at its
Principal Office, not later than 2:00 p.m. on the date on which such payment
shall become due (each such payment made after such time on such due date to be
deemed to have been made on the next succeeding Business Day) and shall be made
as otherwise directed in writing by the Agent from time to time. The Borrower
shall, at the time of making each payment under this Agreement or any Note,
specify to the Agent the amounts payable by the Borrower hereunder to which such
payment is to be applied. Each payment received by the Agent for the account of
a Lender under this Agreement or any Note shall be paid to such Lender at the
applicable Lending Office of such Lender no later than 5:00 p.m. on the date of
receipt. Each payment received by Agent for the account of Swingline Lender
under this Agreement or the Swingline Note shall be paid to Swingline Lender by
wire transfer of immediately available funds in accordance with the wiring
instructions provided by Swingline Lender to the Agent from time to time. If the
due date of any payment under this Agreement or any other Loan Document would
otherwise fall on a day which is not a Business Day such date shall be extended
to the next succeeding Business Day and interest shall be payable for the period
of such extension.

SECTION 3.2.  PRO RATA TREATMENT.

         Except to the extent otherwise provided herein: (a) each borrowing from
the Lenders under Section 2.1.(a) shall be made from the Lenders, each payment
of the Fees under Section 3.6.(a) and 3.6.(b) shall be made for the account of
the Lenders, and each termination or reduction of the amount of the Commitments
under Section 2.9. shall be applied to the respective Commitments of the
Lenders, pro rata according to the amounts of their respective Commitments; (b)
each payment or prepayment of principal of Revolving Loans by the Borrower shall
be made for the account of the Lenders pro rata in accordance with the
respective unpaid principal amounts of the Revolving Loans held by them,
provided that if immediately prior to giving effect to any such payment in
respect of any Revolving Loans the outstanding principal amount of the Revolving
Loans shall not be held by the Lenders pro rata in accordance with their
respective Commitments in effect at the time such Loans were made, then such
payment shall be applied to the Revolving Loans in such manner as shall result,
as nearly as is practicable, in the outstanding principal amount of the
Revolving Loans being held by the Lenders pro rata in accordance with their
respective Commitments; (c) each payment of interest on Revolving Loans by the
Borrower shall be made for the account of the Lenders pro rata in accordance
with the amounts of interest on such Loans then due and payable to the
respective Lenders; (d) the making, Conversion and Continuation of Revolving
Loans of a particular Type (other than Conversions provided for by Section 4.6.)
shall be made pro rata among the Lenders according to the amounts of their
respective Commitments (in the case of making of Loans) or their respective
Loans of such Type (in the case of Conversions and Continuations of Loans) and
the then current Interest Period for each Lender's portion of each Loan of such
Type shall be coterminous and (e) the Lenders' participation in, and payment
obligations in respect of, Swingline Loans under Section 2.10., shall be pro
rata in accordance with their respective Commitments.

SECTION 3.3.  SHARING OF PAYMENTS, ETC.

         The Borrower agrees that, in addition to (and without limitation of)
any right of set-off, banker's lien or counterclaim a Lender or the Agent may
otherwise have, each Lender shall be entitled, at its option but subject to
receipt of the Agent's prior written consent, to offset balances held by such
Lender for the account of the Borrower at any of such Lender's offices, in
Dollars or in any other currency, against any principal of, or interest on, any
of such Lender's Loans hereunder (or other Obligations owing to such Lender
hereunder) which is not paid when due (regardless of whether such balances are
then due to the Borrower), in which case such Lender shall promptly notify the
Borrower, all other Lenders and the Agent thereof; provided, however, such
Lender's failure to give such notice shall not affect the validity of such
offset. If a Lender shall obtain payment of any principal of, or interest on,
any Loan made by it to the Borrower under this Agreement, or shall obtain
payment on any other Obligation owing by the Borrower or a Loan Party through
the exercise of any right of set-off, banker's lien or counterclaim or similar
right or otherwise or through voluntary prepayments directly to a Lender or
other payments made by the Borrower to a Lender not in accordance with the terms
of this Agreement and such payment should be distributed to the Lenders pro rata
in accordance with Section 3.2. or Section 10.3., as applicable, such Lender
shall promptly purchase from the other Lenders participations in (or, if and to
the extent specified by such Lender, direct interests in) the Loans made by the
other Lenders or other Obligations owed to such other Lenders in such amounts,
pay


                                      -28-
<PAGE>   34

such amounts to the other Lenders and make such other adjustments from time to
time as shall be equitable, to the end that all the Lenders shall share the
benefit of such payment (net of any reasonable expenses which may be incurred by
such Lender in obtaining or preserving such benefit) pro rata in accordance with
Section 3.2. or Section 10.3. To such end, all the Lenders shall make
appropriate adjustments among themselves (by the resale of participations sold
or otherwise) if such payment is rescinded or must otherwise be restored. The
Borrower agrees that any Lender so purchasing a participation (or direct
interest) in the Loans or other Obligations owed to such other Lenders may
exercise all rights of set-off, banker's lien, counterclaim or similar rights
with respect to such participation as fully as if such Lender were a direct
holder of Loans in the amount of such participation. Nothing contained herein
shall require any Lender to exercise any such right or shall affect the right of
any Lender to exercise, and retain the benefits of exercising, any such right
with respect to any other indebtedness or obligation of the Borrower. All
payments of principal, interest, fees and other amounts in respect of the
Swingline Loans shall be for the account of Swingline Lender only (except to the
extent any Lender shall have acquired a participating interest in any such
Swingline Loan pursuant to Section 2.10.(e)).

SECTION 3.4.  SEVERAL OBLIGATIONS.

         No Lender shall be responsible for the failure of any other Lender to
make a Loan or to perform any other obligation to be made or performed by such
other Lender hereunder, and the failure of any Lender to make a Loan or to
perform any other obligation to be made or performed by it hereunder shall not
relieve the obligation of any other Lender to make any Loan or to perform any
other obligation to be made or performed by such other Lender.

SECTION 3.5.  MINIMUM AMOUNTS.

         (a) Borrowings. Each borrowing of Base Rate Loans shall be in an
aggregate minimum amount of $1,000,000 and integral multiples of $100,000 in
excess thereof. Each borrowing of LIBOR Loans, and each Conversion of a Loan to
a LIBOR Loan, shall be in an aggregate minimum amount of $1,000,000 and integral
multiples of $100,000 in excess thereof.

         (b) Prepayments. Each voluntary prepayment of Revolving Loans shall be
in an aggregate minimum amount of $1,000,000 and integral multiples of $100,000
in excess thereof.

         (c) Reductions of Commitment. Each reduction of the Commitments under
Section 2.9. shall be in an aggregate minimum amount of $100,000 and integral
multiples of $50,000 in excess thereof.

SECTION 3.6.  FEES.

         (a) Closing Fee. In consideration of the extension of the credit
facility established hereby, the Borrower agrees to pay to the Agent for the
account of each Lender on the Effective Date a closing fee in an amount equal to
one-quarter of one percent (0.25%) of the amount of such Lender's Commitment.

                                      -29-
<PAGE>   35

         (b) Commitment Fee. The Borrower agrees to pay to the Agent for the
account of the Lenders a commitment fee on the average daily amount by which the
Commitments (as the amount of the Commitments may be reduced from time to time
pursuant to Section 2.9. or otherwise) exceed the aggregate outstanding
principal balance of Revolving Loans at a rate per annum equal to the Applicable
Commitment Fee for the period from and including the Agreement Date to but
excluding the date the Commitments are terminated or reduced to zero or the
Termination Date. Such facility fee shall be payable in arrears on (i) the last
Business Day of March, June, September and December in each year commencing with
September 30, 1998, (ii) on the Termination Date, (iii) on the date the
Commitments are otherwise terminated or reduced to zero and (iv) thereafter from
time to time on demand of the Agent.


         (c) Agent, Arranger and Other Fees. The Borrower agrees to pay the
administrative fees, arrangement fees and other fees of the Agent and NMS as may
be agreed to in writing from time to time.

SECTION 3.7.  COMPUTATIONS.

         Unless otherwise expressly set forth herein, (a) any accrued interest
on any Base Rate Loan and any Fees due hereunder shall be computed on the basis
of a year of 365 or 366 days, as appropriate, and the actual number of days
elapsed and (b) any accrued interest on any LIBOR Loan shall be computed on the
basis of a year of 360 days and the actual number of days elapsed.

SECTION 3.8.  USURY.

         In no event shall the amount of interest due or payable on the Loans or
other Obligations exceed the maximum rate of interest allowed by Applicable Law
and, if any such payment is paid by the Borrower or received by any Lender, then
such excess sum shall be credited as a payment of principal, unless the Borrower
shall notify the respective Lender (with a copy to the Agent) 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 Lenders
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 3.9.  AGREEMENT REGARDING INTEREST AND CHARGES.

         The parties hereto hereby agree and stipulate that the only charge
imposed upon the Borrower for the use of money in connection with this Agreement
is and shall be the interest specifically described in Section 2.2.(a) and, with
respect to Swingline Loans, in Section 2.10.(c). Notwithstanding the foregoing,
the parties hereto further agree and stipulate that all commitment fees,
underwriting fees, agency fees, syndication fees, default charges, late charges,
funding or "breakage" charges, increased cost charges, attorneys' fees and
reimbursement for costs and expenses paid by the Agent or any Lender to third
parties or for damages incurred by the Agent or any Lender, are charges made to
compensate the Agent or such Lender for underwriting or administrative services
and costs or losses performed or incurred, and to be performed or incurred, by
the Agent and the Lenders in connection with this Agreement and shall under no


                                      -30-
<PAGE>   36

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.

SECTION 3.10.  STATEMENTS OF ACCOUNT.

         The Agent 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 Agent shall be
deemed presumptively correct. The failure of the Agent to deliver such a
statement of accounts shall not relieve or discharge the Borrower from any of
its obligations hereunder.

SECTION 3.11.  DEFAULTING LENDERS.

         (a) Generally. If for any reason any Lender (a "Defaulting Lender")
shall fail or refuse to perform any of its obligations under this Agreement or
any other Loan Document to which it is a party within the time period specified
for performance of such obligation or, if no time period is specified, if such
failure or refusal continues for a period of two Business Days after notice from
the Agent, then, in addition to the rights and remedies that may be available to
the Agent or the Borrower under this Agreement or Applicable Law, such
Defaulting Lender's right to participate in the administration of the Loans,
this Agreement and the other Loan Documents, including without limitation, any
right to vote in respect of, to consent to or to direct any action or inaction
of the Agent or to be taken into account in the calculation of the Requisite
Lenders, shall be suspended during the pendency of such failure or refusal. If a
Lender is a Defaulting Lender because it has failed to make timely payment to
the Agent of any amount required to be paid to the Agent hereunder (without
giving effect to any notice or cure periods), in addition to other rights and
remedies which the Agent or the Borrower may have under the immediately
preceding provisions or otherwise, the Agent shall be entitled (i) to collect
interest from such Defaulting Lender on such delinquent payment for the period
from the date on which the payment was due until the date on which the payment
is made at the Federal Funds Rate, (ii) to withhold or setoff and to apply in
satisfaction of the defaulted payment and any related interest, any amounts
otherwise payable to such Defaulting Lender under this Agreement or any other
Loan Document and (iii) to bring an action or suit against such Defaulting
Lender in a court of competent jurisdiction to recover the defaulted amount and
any related interest. Any amounts received by the Agent in respect of a
Defaulting Lender's Loans shall not be paid to such Defaulting Lender and shall
be held uninvested by the Agent and either applied against the purchase price of
such Loans under the following subsection (b) or paid to such Defaulting Lender
upon the Defaulting Lender's curing of its default.

         (b) Purchase of Defaulting Lender's Commitment. Any Lender who is not a
Defaulting Lender shall have the right, but not the obligation, in its sole
discretion, to acquire all of a Defaulting Lender's Commitment. Any Lender
desiring to exercise such right shall give written notice thereof to the Agent
no sooner than 10 Business Days and not later than 15 Business Days after such
Defaulting Lender became a Defaulting Lender. If more than one Lender exercises
such right, each such Lender shall have the right to acquire an amount of such
Defaulting Lender's Commitment in proportion to the Commitments of the other
Lenders 


                                      -31-
<PAGE>   37

exercising such right. Upon any such purchase, the Defaulting Lender's
interest in the Loans and its rights hereunder (but not its liability in respect
thereof or under the Loan Documents or this Agreement to the extent the same
relate to the period prior to the effective date of the purchase) shall
terminate on the date of purchase, and the Defaulting Lender shall promptly
execute all documents reasonably requested to surrender and transfer such
interest to the purchaser thereof, including an appropriate Assignment and
Acceptance Agreement and, notwithstanding Section 12.6.(d), shall pay to the
Agent an assignment fee in the amount of $7,000. The purchase price for the
Commitment of a Defaulting Lender shall be equal to the amount of the principal
balance of the Loans outstanding and owed by the Borrower to the Defaulting
Lender. Prior to payment of such purchase price to a Defaulting Lender, the
Agent shall apply against such purchase price any amounts retained by the Agent
pursuant to the last sentence of the immediately preceding subsection (a). The
Defaulting Lender shall be entitled to receive amounts owed to it by the
Borrower under the Loan Documents which accrued prior to the date of the default
by the Defaulting Lender, to the extent the same are received by the Agent from
or on behalf of the Borrower. There shall be no recourse against any Lender or
the Agent for the payment of such sums except to the extent of the receipt of
payments from any other party or in respect of the Loans.

SECTION 3.12. 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 Agent or a Lender and the
jurisdiction imposing such taxes (other than a connection arising solely by
virtue of the activities of the Agent or such 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, (iv) any taxes imposed on
or measured by the Agent's or any Lender's assets, net income, receipts or
branch profits and (v) any taxes arising after the Agreement Date solely as a
result of or attributable to a Lender changing its designated Lending Office
after the date such Lender becomes a party hereto (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 Agent an official receipt or
         other documentation satisfactory to the Agent evidencing such payment
         to such Governmental Authority; and

             (iii) pay to the Agent for its account or the account of the
         applicable Lender, as the case may be, such additional amount or
         amounts as is necessary to ensure that the net 


                                      -32-
<PAGE>   38

         amount actually received by the Agent or such Lender will equal the
         full amount that the Agent or such 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 Agent for
its account or the account of the respective Lender, as the case may be, the
required receipts or other required documentary evidence, the Borrower shall
indemnify the Agent and the Lenders for any incremental Taxes, interest or
penalties that may become payable by the Agent or any Lender as a result of any
such failure. For purposes of this Section, a distribution hereunder by the
Agent or any Lender to or for the account of any Lender shall be deemed a
payment by the Borrower.

         (c) Tax Forms. Prior to the date that any Lender or participant
organized under the laws of a jurisdiction outside the United States of America
becomes a party hereto, such Person shall deliver to the Borrower and the Agent
such certificates, documents or other evidence, as required by the Internal
Revenue Code or Treasury Regulations issued pursuant thereto (including Internal
Revenue Service Forms 4224 or 1001, as applicable, or appropriate successor
forms), properly completed, currently effective and duly executed by such Lender
or participant establishing that payments to it hereunder and under the Notes
are (i) not subject to United States Federal backup withholding tax or (ii) not
subject to United States Federal withholding tax under the Code because such
payment is either effectively connected with the conduct by such Lender or
participant of a trade or business in the United States or totally exempt from
United States Federal withholding tax by reason of the application of the
provisions of a treaty to which the United States is a party or such Lender is
otherwise exempt.

                        ARTICLE IV. YIELD PROTECTION, ETC.

SECTION 4.1. ADDITIONAL COSTS; CAPITAL ADEQUACY.

         (a) Additional Costs. The Borrower shall promptly pay to the Agent for
the account of a Lender from time to time such amounts as such Lender may
reasonably determine to be necessary to compensate such Lender for any costs
incurred by such 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 such 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 such 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 such Lender under this Agreement or any of the other Loan Documents in
respect of any of such Loans or its Commitments (other than taxes imposed on or
measured by the overall net income of such Lender or of its Lending Office for
any of such Loans by the jurisdiction in which such Lender has its principal
office or such Lending Office); or (ii) imposes or modifies any reserve, special
deposit or similar requirements (including, without limitation, any reserves
required to be maintained against (1) "Eurocurrency liabilities" as specified in
Regulation D of the Board of Governors of the Federal Reserve System or (2) any
other category of liabilities which includes deposits by reference to which the
interest rate on 


                                      -33-
<PAGE>   39

LIBOR Loans is determined or (3) any category of extensions of credit or other
assets which includes loans by an office of any 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, such Lender, or any commitment of such Lender (including,
without limitation, the Commitments of such Lender); or (iii) has or would have
the effect of reducing the rate of return on capital of such Lender to a level
below that which such Lender could have achieved but for such Regulatory Change
(taking into consideration such 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, any 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 such 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 such 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 such
Lender so elects by notice to the Borrower (with a copy to the Agent), the
obligation of such 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 4.6. shall
apply).

         (c) Notification and Determination of Additional Costs. Each Lender
agrees to notify the Borrower (with a copy to the Agent) of any event occurring
after the Agreement Date entitling such Lender to compensation under any of the
preceding subsections of this Section as promptly as practicable; provided,
however, subject to the last sentence of this subsection, the failure of any
Lender to give such notice shall not release the Borrower from any of its
obligations hereunder. Such Lender agrees to furnish to the Borrower a
certificate setting forth in reasonable detail the basis and amount of each
request by such Lender for compensation under this Section. Determinations by
such 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. A
Lender shall only be entitled to compensation under this Section for events of
which the Borrower has been provided notice during the 180 day period after the
occurrence of any such event entitling such 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 Agent determines (which determination shall be
         conclusive) that by reason of circumstances affecting the relevant
         market, adequate and reasonable means do not exist for ascertaining
         LIBOR for such Interest Period, or

                                      -34-
<PAGE>   40

                  (b) the Agent determines (which determination shall be
         conclusive) that LIBOR will not adequately and fairly reflect the cost
         to the Lenders of making or maintaining LIBOR Loans for such Interest
         Period;

then the Agent shall give the Borrower and each Lender prompt notice thereof
and, so long as such condition remains in effect, the Lenders 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 any Lender or its Lending Office to honor its obligation to make or
maintain LIBOR Loans hereunder, then such Lender shall promptly notify the
Borrower thereof (with a copy to the Agent) and such 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 such Lender may again make and maintain LIBOR Loans
(in which case the provisions of Section 4.6. shall be applicable).

SECTION 4.4  COMPENSATION.

         The Borrower shall pay to the Agent for the account of each Lender,
upon the request of such Lender through the Agent, such amount or amounts as
shall be sufficient (in the reasonable opinion of such Lender) to compensate it
for any loss, cost or expense that such 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 such 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 such 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 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 such 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 


                                      -35-
<PAGE>   41

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 such Lender). Upon the Borrower's
request, if any Lender shall request compensation under this Section, such
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.  AFFECTED LENDERS.

         If any Lender requests compensation pursuant to Section 3.12. or 4.1.,
or the obligation of any 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), 4.2. or 4.3., then, so long as there does not then exist any Default or
Event of Default, the Borrower may either (a) demand that such Lender (the
"Affected Lender"), and upon such demand the Affected Lender shall promptly,
assign its Commitments to an Eligible Assignee subject to and in accordance with
the provisions of Section 12.6.(d) for a purchase price equal to the aggregate
principal balance of Loans then owing to the Affected Lender plus any accrued
but unpaid interest thereon and accrued but unpaid fees owing to the Affected
Lender, or (b) pay to the Affected Lender the aggregate principal balance of
Loans then owing to the Affected Lender plus any accrued but unpaid interest
thereon and accrued but unpaid fees owing to the Affected Lender, whereupon the
Affected Lender shall no longer be a party hereto or have any rights or
obligations hereunder or under any of the other Loan Documents. Each of the
Agent and the Affected Lender shall reasonably cooperate in effectuating the
replacement of such Affected Lender under this Section, but at no time shall the
Agent, such Affected Lender nor any other Lender be obligated in any way
whatsoever to initiate any such replacement or to assist in finding an Eligible
Assignee. The exercise by the Borrower of its rights under this Section shall be
at the Borrower's sole cost and expenses and at no cost or expense to the Agent,
the Affected Lender or any of the other Lenders. The terms of this Section shall
not in any way limit the Borrower's obligation to pay to any Affected Lender
compensation owing to such Affected Lender pursuant to Section 3.12. or 4.1.

SECTION 4.6.  TREATMENT OF AFFECTED LOANS.

         If the obligation of any 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 of such Lender's 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 such
Lender may specify to the Borrower (with a copy to the Agent)) and, unless and
until such 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 such Lender's LIBOR Loans have been so
         Converted, all payments and prepayments of principal that would
         otherwise be applied to such Lender's LIBOR Loans shall be applied
         instead to its Base Rate Loans; and

                                      -36-
<PAGE>   42

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

If such Lender gives notice to the Borrower (with a copy to the Agent) that the
circumstances specified in Section 4.1. or 4.3. that gave rise to the Conversion
of such Lender's LIBOR Loans pursuant to this Section no longer exist (which
such Lender agrees to do promptly upon such circumstances ceasing to exist) at a
time when LIBOR Loans made by other Lenders are outstanding, then such Lender's
Base Rate Loans shall be automatically Converted, on the first day(s) of the
next succeeding Interest Period(s) for such outstanding LIBOR Loans, to the
extent necessary so that, after giving effect thereto, all Loans held by the
Lenders holding LIBOR Loans and by such Lender are held pro rata (as to
principal amounts, Types and Interest Periods) in accordance with their
respective Commitments.

SECTION 4.7.  CHANGE OF LENDING OFFICE.

         Each Lender agrees that it will use reasonable efforts to designate an
alternate Lending Office with respect to any of its Loans affected by the
matters or circumstances described in Sections 3.12., 4.1. or 4.3. to reduce the
liability of the Borrower or avoid the results provided thereunder, so long as
such designation is not disadvantageous to such Lender as determined by such
Lender in its sole discretion, except that such Lender shall have no obligation
to designate a Lending Office located in the United States of America.

<PAGE>   45

         (c) the Agent 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 Lenders and the Swingline Lender to enter into
this Agreement and to make Loans and the Swingline Loans, as applicable, the
Borrower represents and warrants to the Agent, the Lenders and the Swingline
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) no Subsidiary of the Borrower has issued to any third
party any securities convertible into 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.

         (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 accordance with its respective terms, except
that the enforceability thereof may be limited by


                                      -40-
<PAGE>   46
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 Agent for the benefit of the Lenders.

         (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
material 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, any other Loan Party, any
of their respective property or any Transaction in any court or before any
arbitrator of any kind or before or by any Governmental Authority which if
adversely 


                                      -41-
<PAGE>   47

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 Agent and
each Lender each of the following financial statements: (i) the audited
consolidated balance sheets of the Borrower and its Subsidiaries as at December
31, 1996 and December 31, 1997, and the related consolidated statements of
income, retained earnings and cash flow for the fiscal years then ended; (ii) an
unaudited consolidated balance sheet of the Borrower and its Subsidiaries as at
March 31, 1998, and the related unaudited consolidated statements of income,
retained earnings and cash flow for the fiscal quarter then ended (together with
the financial statements referenced in the immediately proceeding clause (i),
the "Historical Financial Statements"); (iii) a pro forma projected unaudited
consolidated balance sheet of the Borrower and its Subsidiaries as of March 31,
1998 after giving effect to any Acquisition effected prior to the Effective Date
but after December 31, 1997 (the "Pro Forma Financial Statements"); and (iv) 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 four-year period ending
December 31, 2002 (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, 1997, 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
Agent and the Lenders 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


                                      -42-
<PAGE>   48

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 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 shall be submitted (within the applicable
         remedial amendment period, as described in Section 401(b) of the
         Internal Revenue Code) to the Internal Revenue Service for
         determination that it isso qualified, and each trust related to such
         plan shall also be timely submitted to the Internal Revenue Service for
         a determination that it is 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 


                                      -43-
<PAGE>   49

         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.

                  (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.

         (m) Absence of Defaults. No Loan Party is in default under its articles
of incorporation, or other applicable organizational documents, and no event has
occurred, which has not been remedied, cured or waived: (i) which constitutes a
Default or an Event of Default; or (ii) which constitutes, or which with the
passage of time, the giving of notice or otherwise, would constitute a default
or event of default of any Loan Party under any agreement or judgment, decree or
order to which any Loan Party is a party or by which any Loan Party or any of
its properties may be bound which could reasonably be expected to have a
Material Adverse Effect.

         (n) Environmental Laws. Each other Loan Party has obtained all
Governmental Approvals which are required under Environmental Laws and is in
compliance with all terms and conditions of such Governmental Approvals, except
where the failure to be in compliance could not reasonably be expected to have a
Material Adverse Effect. Each of the Borrower, its Subsidiaries and each other
Loan Party is also in compliance with all other limitations, restrictions,
conditions, standards, prohibitions, requirements, obligations, schedules, and
timetables contained in the Environmental Laws, except where the failure to be
in compliance could not reasonably be expected to have a Material Adverse
Effect. The Borrower is not aware of, and has not received notice of, any past,
present, or future events, conditions, circumstances, activities, practices,
incidents, actions, or plans which, with respect to the Borrower, its
Subsidiaries and each other Loan Party, may interfere with or prevent compliance
or continued compliance with Environmental Laws, or may give rise to any
common-law or legal liability, or otherwise form the basis of any claim, action,
demand, suit, proceeding, hearing, study, or investigation, based on or related
to the manufacture, processing, distribution, use, treatment, storage, disposal,
transport, or handling or the emission, discharge, release or threatened release
into the environment, of any pollutant, contaminant, chemical, or industrial,
toxic, or other Hazardous Material which could reasonably be expected to have a
Material Adverse Effect; and there is no civil, criminal, or administrative
action, suit, demand, claim, hearing, notice, or demand letter, notice of
violation, investigation, or proceeding pending or, to the Borrower's knowledge,
threatened, against the Borrower, its Subsidiaries and each other Loan Party
relating in any way to Environmental Laws which, if adversely determined, could
reasonably be expected to have a Material Adverse Effect.



                                      -44-
<PAGE>   50

         (o) Adverse Contracts. None of the Loan Parties has assumed liability
under or is a party to nor is it or any of its property subject to or bound by
any forward purchase contract, futures contract, covenant not to compete,
unconditional purchase, take or pay or other agreement which restricts its
ability to conduct its business, or which, singly or in the aggregate, could
reasonably be expected to have a Material Adverse Effect.

         (p) Investment Company; Public Utility Holding Company. Neither the
Borrower, nor any Subsidiary nor any other Loan Party is (i) an "investment
company" or a company "controlled" by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended, (ii) a "holding company" or a

buying or carrying "margin stock" within the meaning of Regulations U and X of
the Board of Governors of the Federal Reserve System, and no part of the
proceeds of any extension of credit hereunder will be used to buy or carry any

         (r) Affiliate Transactions. As of the Agreement Date, except as set

         (aa) Accuracy and Completeness of Information. All written information,
reports and other papers and data (other than Projections (as defined below))
furnished to the Agent, any Lender or the Swingline Lender by, on behalf of, or
at the direction of, the Borrower or any other Loan Party were, at the time the
same were so furnished, complete and correct in all material respects, to the
extent necessary to give the recipient a true and accurate knowledge of the
subject matter, or, in the case of financial statements, present fairly, in
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. All financial projections concerning the
Borrower or any of its Subsidiaries that have been or are hereafter made
available to the Agent or any Lender by, on behalf of, or at the direction of,
the Borrower or any other Loan Party ("Projections") have been or will be
prepared in good faith based on reasonable assumptions. 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 they engage), no fact is known to the Borrower which
has had, or which would reasonably be expected in the future to have (so far as
the Borrower can reasonably foresee), a Material Adverse Effect which has not
been set forth in the financial statements, information, reports or other papers
or data furnished to, or otherwise disclosed in writing to, the Agent, the
Lenders and the Swingline Lender prior to the Effective Date. No document
furnished or written statement made to the Agent, any Lender or the Swingline
Lender in connection with the negotiation, preparation of execution of this
Agreement or any of the other Loan Documents contains or will contain any untrue
statement of a fact material to the creditworthiness of the Borrower or any
other Loan Party or omits or will omit to state a material fact necessary in
order to make the statements contained therein not misleading.

         (bb) Year 2000. The Borrower reasonably believes that the "Year 2000
Problem" (that is, the inability of computers, as well as embedded microchips in
non-computing devices, to perform properly, including performance of
date-sensitive functions with respect to certain dates prior to and after
December 31, 1999), including costs of remediation, could not reasonably be
expected to result in a Default or Event of Default or to have a Material
Adverse Effect. The computer systems of the Borrower and its Subsidiaries are
and, with ordinary course upgrading and maintenance, will continue for the term
of this Agreement to be, sufficient for the conduct of their business as
currently conducted.

SECTION 6.2. SURVIVAL OF REPRESENTATIONS AND WARRANTIES, ETC.

other instrument delivered by or on behalf of any Loan Party to the Agent, any

the Agent, any Lender or the Swingline Lender in connection with closing the

(b) the date of the making of a Loan any of the proceeds of which are used in
whole or in part to finance such Acquisition.

SECTION 6.4.  REPRESENTATIONS AND WARRANTIES IN ACQUISITION DOCUMENTS

         Each representation and warranty made or deemed made by any Loan Party
in any of the other Loan Documents or the Acquisition Documents is hereby deemed
made to and for the benefit of the Agent, the Lenders and the Swingline Lender
as if the same were set forth herein in full. Except as disclosed by the
Borrower to the Agent, the Lenders and the Swingline Lender in writing, the
Borrower is not aware, and the Borrower has no reason to be aware, that any
representation or warranty by any other party to an Acquisition Document
contained in such Acquisition Document is or was untrue in any material respect
at the time made or deemed made.

which adequate reserves have been established on the books of the Borrower or

expiration of any cure or grace periods set forth herein. In such event, the
Borrower shall, at the request of the Agent, promptly pay any amount reasonably
expended by the Agent in such performance or attempted performance to the Agent,
together with interest thereon at the applicable Post-Default Rate from the date

<PAGE>   76

any of them may otherwise have under Applicable Law. In exercising their
respective rights and remedies the Agent and the Lenders may be selective and no
failure or delay by the Agent or any 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.

                              ARTICLE XI. THE AGENT

SECTION 11.1. AUTHORIZATION AND ACTION.

         Each Lender hereby appoints and authorizes the Agent to take such
action as contractual representative on such Lender's behalf and to exercise
such powers under this Agreement and the other Loan Documents as are
specifically delegated to the Agent by the terms hereof and thereof, together
with such powers as are reasonably incidental thereto. Nothing herein shall be
construed to deem the Agent a trustee or fiduciary for any Lender nor to impose
on the Agent duties or obligations other than those expressly provided for
herein. At the request of a Lender, the Agent will forward to such Lender copies
or, where appropriate, originals of the documents delivered to the Agent
pursuant to this Agreement or the other Loan Documents. The Agent will also
furnish to any Lender, upon the request of such Lender, a copy of any
certificate or notice furnished to the Agent by the Borrower, any Loan Party or
any other Affiliate of the Borrower, pursuant to this Agreement or any other
Loan Document not already delivered to such Lender pursuant to the terms of this
Agreement or any such other Loan Document. As to any matters not expressly
provided for by the Loan Documents (including, without limitation, enforcement
or collection of any of the Obligations), the Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Requisite Lenders (or all of the
Lenders if explicitly required under any other provision of this Agreement), and
such instructions shall be binding upon all Lenders and all holders of any of
the Obligations; provided, however, that, notwithstanding anything in this
Agreement to the contrary, the Agent shall not be required to take any action
which exposes the Agent to personal liability or which is contrary to this
Agreement or any other Loan Document or Applicable Law. Not in limitation of the
foregoing, the Agent shall not exercise any right or remedy it or the Lenders
may have under any Loan Document upon the occurrence of a Default or an Event of
Default unless the Requisite Lenders have so directed the Agent to exercise such
right or remedy.

SECTION 11.2. AGENT'S RELIANCE, ETC.

         Notwithstanding any other provisions of this Agreement or any other
Loan Documents, neither the Agent nor any of its directors, officers, agents,
employees or counsel shall be liable for any action taken or omitted to be taken
by it or them under or in connection with this Agreement, except for its or
their own gross negligence or willful misconduct. Without limiting the
generality of the foregoing, the Agent: (a) may treat the payee of any Note as
the holder thereof until the Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form satisfactory to the Agent; (b)
may consult with legal counsel (including its own counsel or counsel for the
Borrower or any Loan Party), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken 


                                      -71-
<PAGE>   77

in good faith by it in accordance with the advice of such counsel, accountants
or experts; (c) makes no warranty or representation to any Lender or any other
Person and shall not be responsible to any Lender or any other Person for any
statements, warranties or representations made by any Person in or in connection
with this Agreement or any other Loan Document; (d) shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the terms,
covenants or conditions of any of this Agreement or any other Loan Document or
the satisfaction of any conditions precedent under this Agreement or any Loan
Document on the part of the Borrower or other Persons or inspect the property,
books or records of the Borrower or any other Person; (e) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or any other
Loan Document, any other instrument or document furnished pursuant thereto or
any Collateral covered thereby or the perfection or priority of any Lien in
favor of the Agent on behalf of the Lenders in any such Collateral; and (f)
shall incur no liability under or in respect of this Agreement or any other Loan
Document by acting upon any notice, consent, certificate or other instrument or
writing (which may be by telephone or telecopy) believed by it to be genuine and
signed, sent or given by the proper party or parties.

SECTION 11.3.  NOTICE OF DEFAULTS.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of a Default or Event of Default unless the Agent has received notice
from a Lender or the Borrower referring to this Agreement, describing with
reasonable specificity such Default or Event of Default and stating that such
notice is a "notice of default." If any Lender becomes aware of any Default or
Event of Default, it shall promptly send to the Agent such a "notice of
default." Further, if the Agent receives such a "notice of default", the Agent
shall give prompt notice thereof to the Lenders.

SECTION 11.4. NATIONSBANK AS LENDER.

         NationsBank, as a Lender, shall have the same rights and powers under
this Agreement and any other Loan Document as any other Lender and may exercise
the same as though it were not the Agent; and the term "Lender" or "Lenders"
shall, unless otherwise expressly indicated, include NationsBank in each case in
its individual capacity. NationsBank and its affiliates may each accept deposits
from, maintain deposits or credit balances for, invest in, lend money to, act as
trustee under indentures of, serve as financial advisor to, and generally engage
in any kind of business with the Borrower, any other Loan Party or any other
affiliate thereof as if it were any other bank and without any duty to account
therefor to the other Lenders. Further, the Agent and any affiliate may accept
fees and other consideration from the Borrower for services in connection with
this Agreement and otherwise without having to account for the same to the other
Lenders.

SECTION 11.5.  APPROVALS OF LENDERS.

         All communications from the Agent to any Lender requesting such
Lender's determination, consent, approval or disapproval (a) shall be given in
the form of a written notice to such Lender, (b) shall be accompanied by a
description of the matter or issue as to which such 


                                      -72-
<PAGE>   78

determination, approval, consent or disapproval is requested, or shall advise
such Lender where information, if any, regarding such matter or issue may be
inspected, or shall otherwise describe the matter or issue to be resolved, (c)
shall include, if reasonably requested by such Lender and to the extent not
previously provided to such Lender, written materials and a summary of all oral
information provided to the Agent by the Borrower in respect of the matter or
issue to be resolved, and (d) shall include the Agent's recommended course of
action or determination in respect thereof. Each Lender shall reply promptly,
but in any event within 10 Business Days (or such lesser period as may be
required under the Loan Documents for the Agent to respond). Unless a Lender
shall give written notice to the Agent that it objects to the recommendation or
determination of the Agent (together with a written explanation of the reasons
behind such objection) within the applicable time period for reply, such Lender
shall be deemed to have conclusively approved of or consented to such
recommendation or determination.

SECTION 11.6.  LENDER CREDIT DECISION, ETC.

         Each Lender expressly acknowledges and agrees that neither the Agent,
NMS nor any of their respective officers, directors, employees, agents, counsel,
attorneys-in-fact or other affiliates has made any representations or warranties
as to the financial condition, operations, creditworthiness, solvency or other
information concerning the business or affairs of the Borrower, any other Loan
Party, any Subsidiary or other Person to such Lender and that no act by the
Agent hereinafter taken, including any review of the affairs of the Borrower,
shall be deemed to constitute any such representation or warranty by the Agent
to any Lender. Each Lender acknowledges that it has, independently and without
reliance upon the Agent, NMS, any other Lender or counsel to the Agent or any of
their respective officers, directors, employees and agents, and based on the
financial statements of the Borrower, the Subsidiaries or any other Affiliate
thereof, and inquiries of such Persons, its independent due diligence of the
business and affairs of the Borrower, the Loan Parties, the Subsidiaries and
other Persons, its review of the Loan Documents, the legal opinions required to
be delivered to it hereunder, the advice of its own counsel and such other
documents and information as it has deemed appropriate, made its own credit and
legal analysis and decision to enter into this Agreement and the transaction
contemplated hereby. Each Lender also acknowledges that it will, independently
and without reliance upon the Agent, NMS, any other Lender or counsel to the
Agent or any of their respective officers, directors, employees and agents, and
based on such review, advice, documents and information as it shall deem
appropriate at the time, continue to make its own decisions in taking or not
taking action under the Loan Documents. Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Agent under this Agreement or any of the other Loan Documents, the Agent
shall have no duty or responsibility to provide any Lender with any credit or
other information concerning the business, operations, property, financial and
other condition or creditworthiness of the Borrower, any other Loan Party or any
other Affiliate thereof which may come into possession of the Agent or any of
its officers, directors, employees, agents, attorneys-in-fact or other
Affiliates. Each Lender acknowledges that the Agent's legal counsel in
connection with the transactions contemplated by this Agreement is only acting
as counsel to the Agent and is not acting as counsel to such Lender.

SECTION 11.7.  INDEMNIFICATION OF AGENT.

         Each Lender agrees to indemnify the Agent (to the extent not reimbursed
by the Borrower and without limiting the obligation of the Borrower to do so)
pro rata in accordance with such Lender's respective Commitment Percentage, 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 Agent (in its capacity as Agent but not as a Lender) in any way
relating to or arising out of the Loan Documents, any transaction contemplated
hereby or thereby or any action taken or omitted by the Agent under the Loan
Documents (collectively, "Indemnifiable Amounts"); provided, however, that no
Lender shall be liable for any portion of such Indemnifiable Amounts to the
extent resulting from the Agent's gross negligence or willful misconduct or if
the Agent fails to follow the written direction of the Requisite Lenders unless
such failure is pursuant to the advice of counsel of which the Lenders have
received notice. Without limiting the generality of the foregoing, each Lender
agrees to reimburse the Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including counsel fees of the counsel(s) of the Agent's
own choosing) incurred by the Agent in connection with the preparation,
execution, administration, or enforcement of, or legal advice with respect to
the rights or responsibilities of the parties under, the Loan Documents, any
suit or action brought by the Agent to enforce the terms of the Loan Documents
and/or collect any Obligations, any "lender liability" suit or claim brought
against the Agent and/or the Lenders, and any claim or suit brought against the
Agent and/or the Lenders arising under any Environmental Laws, to the extent
that the Agent is not reimbursed for such expenses by the Borrower. Such
out-of-pocket expenses (including counsel fees) shall be advanced by the Lenders
on the request of the Agent notwithstanding any claim or assertion that the
Agent is not entitled to indemnification hereunder upon receipt of an
undertaking by the Agent that the Agent will reimburse the Lenders if it is
actually and finally determined by a court of competent jurisdiction that the
Agent is not so entitled to indemnification. The agreements in this Section
shall survive the payment of the Loans and all other amounts payable hereunder
or under the other Loan Documents and the termination of this Agreement. If the
Borrower shall reimburse the Agent for any Indemnifiable Amount following
payment by any Lender to the Agent in respect of such Indemnifiable Amount
pursuant to this Section, the Agent shall share such reimbursement on a ratable
basis with each Lender making any such payment.

SECTION 11.8. COLLATERAL MATTERS.

         (a)  The Agent is authorized on behalf of all of the Lenders, without
the necessity of any notice to or further consent from any Lender, from time to
time prior to an Event of Default, to take any action with respect to any
Collateral or Loan Documents which may be necessary to perfect and maintain
perfected the Liens upon the Collateral granted pursuant to any of the Loan
Documents.

         (b)  The Lenders hereby authorize the Agent, at its option and in its
discretion, to release any Lien granted to or held by the Agent upon any
Collateral (i) upon termination of the Commitments and payment and satisfaction
of all of the Obligations at any time arising under or in respect of this
Agreement or the Loan Documents or the transactions contemplated hereby or
thereby; (ii) as explicitly permitted by, but only in accordance with, the terms
of the applicable 


                                      -74-
<PAGE>   80

Loan Document; or (iii) if approved, authorized or ratified in writing by the
Requisite Lenders, unless such release is required to be approved by all of the
Lenders hereunder. Upon request by the Agent at any time, the Lenders will
confirm in writing the Agent's authority to release particular types or items of
Collateral pursuant to this Section.

         (c) Upon any sale and transfer of Collateral which is expressly
permitted pursuant to the terms of this Agreement, or consented to in writing by
the Requisite Lenders or all of the Lenders, as applicable, and upon at least 5
Business Days' prior written request by the Borrower, the Agent shall (and is
hereby irrevocably authorized by the Lenders to) execute such documents as may
be necessary to evidence the release of the Liens granted to the Agent for the
benefit of the Lenders herein or pursuant hereto upon the Collateral that was
sold or transferred; provided, however, that (i) the Agent shall not be required
to execute any such document on terms which, in the Agent's opinion, would
expose the Agent to liability or create any obligation or entail any consequence
other than the release of such Liens without recourse or warranty; and (ii) such
release shall not in any manner discharge, affect or impair the Obligations or
any Liens upon (or obligations of the Borrower or any Loan Party in respect of)
all interests retained by the Borrower or any Subsidiary, including (without
limitation) the proceeds of the sale, all of which shall continue to constitute
part of the Collateral. In the event of any sale or transfer of Collateral, or
any foreclosure with respect to any of the Collateral, the Agent shall be
authorized to deduct all of the expenses reasonably incurred by the Agent from
the proceeds of any such sale, transfer or foreclosure.

         (d) The Agent shall have no obligation whatsoever to the Lenders or to
any other Person to assure that the Collateral exists or is owned by the
Borrower or any Subsidiary or is cared for, protected or insured or that the
Liens granted to the Agent herein or pursuant hereto have been properly or
sufficiently or lawfully created, perfected, protected or enforced or are
entitled to any particular priority, or to exercise or to continue exercising at
all or in any manner or under any duty of care, disclosure or fidelity any of
the rights, authorities and powers granted or available to the Agent in this
Section or in any of the Loan Documents, it being understood and agreed that in
respect of the Collateral, or any act, omission or event related thereto, the
Agent may act in any manner it may deem appropriate, in its sole discretion,
given the Agent's own interest in the Collateral as one of the Lenders and that
the Agent shall have no duty or liability whatsoever to the Lenders, except for
its gross negligence or willful misconduct.

SECTION 11.9. SUCCESSOR AGENT.

         The Agent may resign at any time as Agent under the Loan Documents by
giving written notice thereof to the Lenders and the Borrower. Upon any such
resignation or removal, the Requisite Lenders shall have the right to appoint a
successor Agent which appointment shall, provided no Default or Event of Default
shall have occurred and be continuing, be subject to the Borrower's approval,
which approval shall not be unreasonably withheld or delayed (except that
Borrower shall, in all events, be deemed to have approved each Lender as a
successor Agent). If no successor Agent shall have been so appointed by the
Requisite Lenders, and shall have accepted such appointment, within 30 days
after the resigning Agent's giving of notice of resignation or the Requisite
Lenders' removal of the resigning Agent, then the resigning or 


                                      -75-
<PAGE>   81

removed Agent may, on behalf of the Lenders, appoint a successor Agent, which
shall be a Lender, if any Lender shall be willing to serve, and otherwise shall
be a commercial bank having total combined assets of at least $50,000,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning Agent, and the retiring
Agent shall be discharged from its duties and obligations under the Loan
Documents. After any resigning Agent's resignation or removal hereunder as
Agent, the provisions of this Article XI. shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent under the Loan
Documents.

Agent in connection with the negotiation, preparation, execution and delivery of

and the Lenders in connection with the exercise by the Agent and the Lenders of

and any other indebtedness at any time held or owing by the Agent, such Lender
or any affiliate of the Agent or such Lender, to or for the credit or the

irrespective of whether or not any or all of the Loans and all other Obligations
have been declared to be due and payable as permitted by Section 10.2.

SECTION 12.5. LITIGATION; JURISDICTION; OTHER MATTERS; WAIVERS.

         (a)      EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY
BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON
DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND
EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW,
EACH OF THE LENDERS, THE AGENT AND THE BORROWER HEREBY WAIVES ITS RIGHT TO A
TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR
TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO
ARISING OUT OF THIS AGREEMENT, THE NOTES, 


                                      -78-
<PAGE>   84

OR ANY OTHER LOAN DOCUMENT OR IN CONNECTION WITH ANY COLLATERAL OR ANY LIEN OR
BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER BETWEEN OR
AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS OF ANY KIND OR NATURE.

         (b)      EACH OF THE BORROWER, THE AGENT AND EACH LENDER HEREBY AGREES
THAT THE FEDERAL DISTRICT COURT OF THE NORTHERN DISTRICT OF GEORGIA OR, AT THE
OPTION OF THE AGENT, ANY STATE COURT LOCATED IN FULTON COUNTY, GEORGIA SHALL
HAVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG
THE BORROWER, THE AGENT OR ANY OF THE LENDERS, PERTAINING DIRECTLY OR INDIRECTLY
TO THIS AGREEMENT, THE LOANS, THE NOTES OR ANY OTHER LOAN DOCUMENT OR TO ANY
MATTER ARISING HEREFROM OR THEREFROM OR THE COLLATERAL. THE BORROWER AND EACH OF
THE LENDERS EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN
ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS.

         (c)      EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT
OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH
AGREES NOT TO PLEAD OR CLAIM THE SAME.

         (d)      THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE
DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY LENDER OR THE
ENFORCEMENT BY THE AGENT OR ANY LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN
ANY OTHER APPROPRIATE JURISDICTION.

SECTION 12.6.  SUCCESSORS AND ASSIGNS.

         (a)      The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or otherwise transfer any of
its rights under this Agreement without the prior written consent of all of the
Lenders.

         (b)      Any Lender may make, carry or transfer Loans at, to or for the
account of, any of its branch offices or the office of an affiliate of such
Lender except to the extent such transfer would result in increased costs to the
Borrower.

         (c)      Any Lender may at any time grant to one or more banks or other
financial institutions (each a "Participant") participating interests in its
Commitment or the Obligations owing to such Lender; provided, however, (i) any
such participating interest must be for a constant and not a varying percentage
interest, and (ii) after giving effect to any such participation by a Lender,
the amount of its Commitment, or if the Commitments have been terminated, the
aggregate outstanding principal balance of the Note held by it, in which it has
not


                                      -79-
<PAGE>   85

granted any participating interests must be at least $5,000,000. Except as
otherwise provided in Section 12.4., no Participant shall have any rights or
benefits under this Agreement or any other Loan Document. In the event of any
such grant by a Lender of a participating interest to a Participant, such Lender
shall remain responsible for the performance of its obligations hereunder, and
the Borrower and the Agent shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement. Any agreement pursuant to which any Lender may grant such a
participating interest shall provide that such Lender shall retain the sole
right and responsibility to enforce the obligations of the Borrower hereunder
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement; provided, however, such Lender may
agree with the Participant that it will not, without the consent of the
Participant, agree to (i) increase, or extend the term or extend the time or
waive any requirement for the reduction or termination of, such Lender's
Commitment, (ii) extend the date fixed for the payment of principal of or
interest on the Loans or portions thereof owing to such Lender, (iii) reduce the
amount of any such payment of principal, (iv) reduce the rate at which interest
is payable thereon or (v) any release of all or substantially all of the
Collateral. An assignment or other transfer which is not permitted by subsection
(d) or (f) below shall be given effect for purposes of this Agreement only to
the extent of a participating interest granted in accordance with this
subsection (c). The selling Lender shall notify the Agent and the Borrower of
the sale of any participation hereunder and the terms thereof.

         (d)      Any Lender may with the prior written consent of the Agent and
the Borrower (which consent, in each case, shall not be unreasonably withheld)
assign to one or more Eligible Assignees (each an "Assignee") all or a portion
of its Commitment and its other rights and obligations under this Agreement and
the Notes; provided, however, (i) no such consent by the Borrower shall be
required in the case of any assignment to another Lender or any affiliate of
such Lender or another Lender or if an Event of Default shall have occurred and
be continuing; (ii) any partial assignment shall be in an amount at least equal
to $5,000,000 and after giving effect to such assignment the assigning Lender
retains Commitment, or if the Commitments have been terminated, holds a Note
having an aggregate outstanding principal balance, of at least $5,000,000; and
(iii) each such assignment shall be effected by means of an Assignment and
Acceptance Agreement. Upon execution and delivery of such instrument and payment
by such Assignee to such transferor Lender of an amount equal to the purchase
price agreed between such transferor Lender and such Assignee, such Assignee
shall be deemed to be a Lender party to this Agreement as of the effective date
of the Assignment and Acceptance Agreement and shall have all the rights and
obligations of a Lender with a Commitment as set forth in such Assignment and
Acceptance Agreement, and the transferor Lender shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (d), the transferor Lender, the Agent and the
Borrower shall make appropriate arrangements so that new Notes are issued to the
Assignee and such transferor Lender, as appropriate. In connection with any such
assignment, the transferor Lender shall pay to the Agent an administrative fee
for processing such assignment in the amount of $3,500.

                                      -80-
<PAGE>   86

         (e)      The Agent shall maintain at the Principal Office a copy of
each Assignment and Acceptance Agreement delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the
Commitment of each Lender from time to time (the "Register"). The Agent shall
give each Lender and the Borrower notice of the assignment by any Lender of its
rights as contemplated by this Section. The Borrower, the Agent and the Lenders
may treat each Person whose name is recorded in the Register as a Lender
hereunder for all purposes of this Agreement. The Register and copies of each
Assignment and Acceptance Agreement shall be available for inspection by the
Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice to the Agent. Upon its receipt of an Assignment and
Acceptance Agreement executed by an assigning Lender, together with each Note

furnished pursuant thereto; (iii) makes no representation or warranty and
assumes no responsibility with respect to the financial condition of any Loan

the Revolving Notes in respect of the interest assigned hereby (including,
without limitation, all payments of principal, interest and Fees with respect
thereto) to the Assignee. The Assignor and Assignee shall make all appropriate

     7.   This Assignment and Acceptance Agreement shall be governed by, and

proceeding at law or in equity); provided, however, no representation or
warranty is being made with respect to the enforceability of provisions of any

Services Agreement or (ii) could not reasonably be expected to have a Material
Adverse Effect.

         (d)      Neither such Assignor nor any other Person a party to any
Management Agreement Document is in default under any of the terms, covenants or
conditions of any Management Agreement Document nor, to such Assignor's
knowledge, does there exist any event of default or any state of facts which
would, with the passage of time or the giving of notice, or both, constitute a
default or event of default on the part of such Assignor or any such other
Person under any of said terms, covenants or conditions, which, in either case,
could reasonably be expected to have a Material Adverse Effect.

         (e)      Such Assignor has taken all steps necessary or appropriate to
protect and preserve its rights under the Management Agreement Documents,
including without limitation, the filing of financing statements under the
Uniform Commercial Code as in effect in all applicable jurisdictions.

         (f)      Such Assignor has not assigned any of its right, title or
interest in, to or under any of the Collateral to any Person.

         (g)      Such Assignor has full authority and the legal right to assign
to the Agent, and to grant to the Agent a security interest in, the Management
Agreement Documents and the other Collateral and such Assignor has obtained all
consents necessary for the valid and binding assignment of and the effectiveness
and enforceability of such security interest under this Agreement.

         (h)      All of the Collateral is free and clear of all Liens other
than Permitted Liens.

         SECTION 3. COVENANTS. Each Assignor covenants and agrees as to
each Management Agreement Document as follows:

         (a)      Such Assignor will not sell, assign, grant a Lien in, suffer
to exist any Lien in, or otherwise transfer to any Person any of such Assignor's
right, title or interest in, to or under any of the Collateral.

         (b)      Anything herein to the contrary notwithstanding, (i) such
Assignor shall remain liable under all Management Agreement Documents to the
extent set forth therein to perform its duties and obligations thereunder to the
same extent as if this Agreement had not been executed, (ii) the exercise by the
Agent of any of its rights hereunder shall not release such Assignor from any of
its duties or obligations under any of the Management Agreement Documents, and
(iii) neither the Agent, any Lender nor the Swingline Lender shall have any
duties, obligations or liability under any of the Management Agreement Documents
or duties by reason of this Agreement, nor shall the Agent, any Lender or the
Swingline Lender be obligated to perform any



                                      C-3
<PAGE>   108


of the duties or obligations of such Assignor thereunder, to make any payment,
to make any inquiry as to the nature or sufficiency of any payment received by
such Assignor or the sufficiency of any performance by any party under any such
contract or agreement, or to take any action to collect or enforce any claim for
payment assigned hereunder.

         (c)      Such Assignor shall at its sole cost and expense:

                  (i)      Perform and observe all the terms and provisions of
         the Management Agreement Documents to be performed or observed by it,
         maintain the Management Agreement Documents in full force and effect,
         and enforce the Management Agreement Documents in accordance with their
         terms, except where the failure to do so could not reasonably be
         expected to have a Material Adverse Effect; and

                  (ii)     From time to time (A) furnish to the Agent such
         information and reports regarding the Management Agreement Documents as
         the Agent may reasonably request and (B) upon request of the Agent and
         upon the occurrence and during the continuation of an Event of Default,
         make to each other party to the Management Agreement Documents such
         demands and request for information and reports or for action as such
         Assignor is entitled to make under the Management Agreement Documents.

         SECTION 4. PAYMENTS. So long as no Event of Default shall have
occurred and be continuing, each Assignor shall have the right to receive all
amounts paid or payable in connection with the Management Agreement Documents.
Upon and after the occurrence and continuation of any Event of Default, all
rights of any Assignor to receive any of the payments pursuant to the
immediately preceding sentence shall cease, and all such rights shall thereupon
become vested in the Agent, and the Agent shall have the sole and exclusive
right to receive and retain the payments which any Assignor would otherwise be
authorized to receive and retain pursuant to such sentence.

         SECTION 5. ASSIGNOR'S RIGHT TO ENFORCE. So long as no Event of
Default shall have occurred and be continuing, the Agent will not exercise or
enforce, or seek to exercise or enforce, or avail itself of, any of the rights,
powers, privileges, authorizations and benefits assigned and transferred to the
Agent pursuant to this Agreement, and each Assignor may exercise or enforce, or
seek to exercise or enforce, such rights, powers, privileges, authorizations and
benefits in conformity with the provisions of this Agreement. If any Assignor
shall fail to perform or comply with any term or condition imposed upon such
Assignor under any of the Management Agreement Documents, or any Assignor shall
fail to exercise any right or remedy of such Assignor thereunder, and in either
such case either (a) such failure could reasonably be excepted to have a
Material Adverse Effect or (b) an Event of Default shall have occurred and be
continuing, then, without waiving or releasing such Assignor from any of its
obligations hereunder or under such Management Agreement Document, the Agent may
(but shall not obligated to) take any action the Agent deems necessary or
desirable to preserve and protect any of such Assignor's rights thereunder or
the Agent's rights thereunder.

         SECTION 6. REMEDIES. Upon the occurrence and during the
continuation of an Event of Default, the Agent shall, at its election, without
notice of election and without demand, have the right to do any one or more of
the following acts, all of which are hereby authorized by each Assignor: (a)
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 remedies
under the Credit Agreement and the other Loan Documents.

         SECTION 7. AGENT AND LENDERS NOT OBLIGATED. Notwithstanding any
other provision of this Assignment to the contrary, each 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 Agent, any Lender or the Swingline 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.

         SECTION 8. FURTHER ASSURANCES. At any time and from time to time,
upon the written request of the Agent, and at the sole expense of the Assignors,
each Assignor will promptly execute and deliver such further instruments and
documents and take such further action as the Agent 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
Agent, the Lenders and the Swingline Lender under this Agreement are cumulative
and not exclusive of any rights or remedies which any of them would otherwise
have. In exercising their rights and remedies the Agent, the Lenders and the
Swingline 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. AGENT APPOINTED ATTORNEY-IN-FACT. Each Assignor hereby
irrevocably appoints the Agent as such Assignor's attorney-in-fact, with full
authority in the place and stead of such Assignor and in the name of such
Assignor or otherwise, from time to time upon the occurrence and during the
continuation of an Event of Default in the Agent's discretion, to take any
action and to execute any instrument or document which the Agent may deem
necessary or advisable to accomplish the purposes of this Agreement and to
exercise any rights and remedies the Agent, the Lenders and the Swingline 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 which
the Agent may deem necessary or desirable for the collection of any of the
Collateral or otherwise to enforce the rights of the Agent with respect



                                      C-5

demand, all reasonable fees and expenses actually incurred by the Agent in
connection with (a) the collection or enforcement of the Obligations including
the reasonable fees and disbursements of counsel to the Agent actually incurred
by the Agent and (b) the exercise by the Agent 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. TERMINATION. Upon indefeasible payment in full of all
of the Obligations, this Agreement shall terminate.

         SECTION 14. 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 15. AMENDMENTS, ETC. No amendment or waiver of any
provision of this Agreement, nor consent to any departure by any Assignor
herefrom, shall in any event be effective unless the same shall be done in
accordance with the applicable provisions of the Credit Agreement.

         SECTION 16. SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under Applicable Law, but if any provision of this Agreement shall be prohibited
by or invalid under Applicable Law, such provisions shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provisions or the remaining provisions of this Agreement.

         SECTION 17. GOVERNING LAW. THIS ASSIGNMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA.

         SECTION 18. BENEFITS. This Assignment shall be binding on, and
inure to the benefit of, the parties hereto and their respective successors and

                                    EXHIBIT D

               FORM OF AMENDED, RESTATED AND CONSOLIDATED GUARANTY

         THIS AMENDED, RESTATED AND CONSOLIDATED GUARANTY dated as of July 31,
1998 (this "Guaranty"), executed by each of the undersigned "Guarantors" and the
other Persons from time to time party hereto pursuant to the execution and
delivery of an Accession Agreement in the form of Exhibit A to the Credit
Agreement (as defined below) (all of the undersigned, together with such other
Persons each a "Guarantor" and collectively, the "Guarantors"), in favor of (a)
NATIONSBANK, N.A., successor to NationsBank, N.A. (South), in its capacity as
Agent (the "Agent") for the Lenders under that certain Amended and Restated
Credit Agreement dated as of the date hereof (as the same may be amended,
restated, supplemented or otherwise modified from time to time in accordance
with its terms, the "Credit Agreement") by and among Physicians' Specialty Corp.
(the "Borrower"), the financial institutions initially party thereto and their
assignees under Section 12.6 thereof (the "Lenders") and the Agent and (b) the
Lenders and the Swingline Lender.

         WHEREAS, pursuant to the Credit Agreement the Lenders and the Swingline
Lender have agreed to make available to the Borrower certain financial
accommodations on the terms and conditions set forth in the Credit Agreement;

         WHEREAS, all of the Guarantors are Subsidiaries of the Borrower;

         WHEREAS, the Borrower, each of the Guarantors 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 Lenders and the Swingline Lender through their
collective efforts;

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

         WHEREAS, it is a condition precedent to the continued extension of such
financial accommodations to the Borrower by the Lenders and the Swingline Lender
that each Guarantor execute and deliver this Guaranty.

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

         SECTION 1. GUARANTY. Each 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 




                                      D-1
<PAGE>   114


Agent, the Lenders or the Swingline 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 Revolving
Loans and the Swingline Loans and the payment of all interest, fees, charges,
reasonable attorneys' fees and other amounts payable to the Agent, the Lenders
or the Swingline 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 Agent, the Lenders or
the Swingline Lender in the enforcement of any of the foregoing or any
obligation of such 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 each Guarantor for
its own account. Accordingly, none of the Agent, the Lenders or the Swingline
Lender shall be obligated or required before enforcing this Guaranty against any
Guarantor: (a) to pursue any right or remedy the Agent, any Lender or the
Swingline 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 Agent, any Lender or the
Swingline Lender which may secure any of the Guarantied Obligations. In this
connection, each Guarantor hereby waives the right of such Guarantor to require
any holder of the Guarantied Obligations to take action against the Borrower as
provided in Official Code of Georgia Annotated ss.10-7-24.

         SECTION 3. GUARANTY ABSOLUTE. Each 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
Agent, the Lenders or the Swingline Lender with respect thereto. The liability
of each 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 such 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;



                                      D-2
<PAGE>   115


         (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 Agent, any Lender or the Swingline
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)      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 such
Guarantor, the Borrower, 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, any other Loan
Party or any other Person which may adversely affect such 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 Agent, the
Lenders or the Swingline 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, such Guarantor hereunder.

         SECTION 4. ACTION WITH RESPECT TO GUARANTIED OBLIGATIONS. Each of the
Agent, the Lenders and the Swingline Lender may, at any time and from time to
time, without the consent of, or notice to, any Guarantor, and without
discharging any 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, 



                                      D-3
<PAGE>   116


to the Guarantied Obligations in such order as the Agent, the Lenders or the
Swingline Lender shall elect.

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

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

         SECTION 7. WAIVER. Each 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 such Guarantor or which otherwise might operate to
discharge such Guarantor from its obligations hereunder.

         SECTION 8. INABILITY TO ACCELERATE. If the Agent, any Lender or the
Swingline 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 Agent, such Lender or the Swingline Lender
shall be entitled to receive from such 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
Agent, any Lender or the Swingline Lender for repayment or recovery of any
amount or amounts received in payment or on account of any of the Guarantied
Obligations, and the Agent, such Lender or the Swingline 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 Agent, such Lender or the Swingline
Lender with any such claimant (including the Borrower or a trustee in bankruptcy
for the Borrower), then and in such event such 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, except as expressly provided otherwise in
such judgment, decree, order, settlement or compromise, such Guarantor shall be
and remain liable to the Agent, such Lender and the Swingline Lender for the
amounts so repaid or recovered to the same extent as if such amount had never
originally been paid to the Agent, such Lender or the Swingline Lender.

         SECTION 10. SUBROGATION. Upon the making by any Guarantor of any
payment hereunder for the account of the Borrower, such Guarantor shall be
subrogated to the rights of the payee against such Borrower; provided, however,
that such 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 such Guarantor may have against the Borrower arising by reason of any
payment or performance by such Guarantor pursuant to this Guaranty, unless and
until all of the 



                                      D-4
<PAGE>   117


Guarantied Obligations have been indefeasibly paid and performed in full. If any
amount shall be paid to such Guarantor on account of or in respect of such
subrogation rights or other claims or causes of action, such Guarantor shall
hold such amount in trust for the benefit of the Agent, the Lenders and the
Swingline Lender and shall forthwith pay such amount to the Agent, the Lenders
and the Swingline 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 Agent, the Lenders or the Swingline Lender
as collateral security for any Guarantied Obligations existing.

         SECTION 11. PAYMENTS FREE AND CLEAR. All sums payable by each 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 Taxes), and if a Guarantor is
required by Applicable Law or by any Governmental Authority to make any such
deduction or withholding, such Guarantor shall pay to the Agent, the Lenders or
the Swingline Lender such additional amount as will result in the receipt by the
Agent, the Lenders or the Swingline 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, each Guarantor hereby authorizes each of the
Agent, the Lenders and the Swingline Lender, at any time or from time to time,
without any prior notice to such Guarantor or to any other Person, any such
notice being hereby expressly waived, but subject to receipt of the Agent's
prior written consent, 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 Agent, the Lenders or the
Swingline Lender, or any affiliate of the Agent, the Lenders or the Swingline
Lender, to or for the credit or the account of such Guarantor against and on
account of any of the Guarantied Obligations, although such obligations shall be
contingent or unmatured.

         SECTION 13. SUBORDINATION. Each Guarantor hereby expressly covenants
and agrees for the benefit of the Agent, the Lenders and the Swingline Lender
that all obligations and liabilities of the Borrower to such Guarantor of
whatever description, including without limitation, all intercompany receivables
of such 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 no Guarantor shall
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 each Guarantor,
the Agent, each Lender and the Swingline Lender that in any Proceeding, such
Guarantor's maximum obligation hereunder shall equal, but not exceed, the
maximum amount which would not otherwise cause the obligations of such Guarantor
hereunder (or any other obligations of such Guarantor to the Agent, the Lenders
or the Swingline Lender) to be avoidable or unenforceable against such 



                                      D-5
<PAGE>   118


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 such Guarantor
hereunder (or any other obligations of such Guarantor to the Agent, the Lenders
or the Swingline Lender) shall be determined in any such Proceeding are referred
to as the "Avoidance Provisions". Accordingly, to the extent that the
obligations of any Guarantor hereunder would otherwise be subject to avoidance
under the Avoidance Provisions, the maximum Guarantied Obligations for which
such 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 such
Guarantor hereunder (or any other obligations of such Guarantor to the Agent,
the Lenders or the Swingline Lender), to be subject to avoidance under the
Avoidance Provisions. This Section is intended solely to preserve the rights of
the Agent, the Lenders and the Swingline Lender hereunder to the maximum extent
that would not cause the obligations of any Guarantor hereunder to be subject to
avoidance under the Avoidance Provisions, and no Guarantor or any other Person
shall have any right or claim under this Section as against the Agent, the
Lenders or the Swingline Lender that would not otherwise be available to such
Person under the Avoidance Provisions.

         SECTION 15. INFORMATION. Each Guarantor assumes all responsibility for
being and keeping itself informed of the financial condition of the Borrower and
the other 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 such Guarantor assumes and incurs hereunder, and agrees that
neither the Agent, the Lenders nor the Swingline Lender nor any Lender shall
have any duty whatsoever to advise any 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. LITIGATION; JURISDICTION; OTHER MATTERS; WAIVERS.

         (a)      EACH GUARANTOR AND THE AGENT, AND EACH LENDER AND THE
SWINGLINE LENDER BY ACCEPTING THE BENEFITS HEREOF, ACKNOWLEDGES THAT ANY DISPUTE
OR CONTROVERSY BETWEEN OR AMONG A GUARANTOR, THE AGENT, ANY OF THE LENDERS OR
THE SWINGLINE LENDER WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND
FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE
EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE GUARANTORS, THE AGENT, THE
LENDERS AND THE SWINGLINE LENDER HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN
ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH
AN ACTION MAY BE COMMENCED BY OR AGAINST ANY SUCH PARTY ARISING OUT OF THIS
GUARANTY, OR ANY OTHER




                                      D-6

LOAN DOCUMENT OR IN CONNECTION WITH ANY COLLATERAL OR ANY LIEN OR BY REASON OF
ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER BETWEEN OR AMONG A
GUARANTOR, THE AGENT, ANY LENDER OR THE SWINGLINE LENDER OF ANY KIND OR NATURE.

         (b)      EACH GUARANTOR AND THE AGENT, AND EACH LENDER AND THE
SWINGLINE LENDER BY ACCEPTING THE BENEFITS HEREOF, HEREBY AGREES THAT THE
FEDERAL DISTRICT COURT OF THE NORTHERN DISTRICT OF GEORGIA OR, AT THE OPTION OF
THE AGENT, ANY STATE COURT LOCATED IN FULTON COUNTY, GEORGIA, SHALL HAVE
JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG EACH
GUARANTOR, THE AGENT, ANY LENDER OR THE SWINGLINE LENDER, PERTAINING DIRECTLY OR
INDIRECTLY TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING
HEREFROM OR THEREFROM OR ANY OF THE COLLATERAL. EACH GUARANTOR, THE AGENT AND
EACH LENDER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN
ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS.

         (c)      EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT
OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH
AGREES NOT TO PLEAD OR CLAIM THE SAME.

         (d)      THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE
DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY ANY GUARANTOR, THE AGENT, ANY
LENDER OR THE SWINGLINE LENDER OR THE ENFORCEMENT BY ANY GUARANTOR, THE AGENT,
ANY LENDER OR THE SWINGLINE LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY
OTHER APPROPRIATE JURISDICTION.

         SECTION 18. LOAN ACCOUNTS. The Agent may maintain books and accounts
setting forth the amounts of principal, interest and other sums paid and payable
with respect to the Guarantied Obligations, and in the case of any 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
respect thereto. The failure of the Agent to maintain such books and accounts
shall not in any way relieve or discharge any Guarantor of any of its
obligations hereunder.

         SECTION 19. WAIVER OF REMEDIES. No delay or failure on the part of the
Agent, any Lender or the Swingline Lender in the exercise of any right or remedy
it may have against any Guarantor hereunder or otherwise shall operate as a
waiver thereof, and no single or partial exercise by the Agent, any Lender or
the Swingline Lender of any such right or remedy shall preclude other or further
exercise thereof or the exercise of any other such right or remedy.

any Lender or the Swingline Lender shall be deemed to include the permitted
successors and assigns of the Agent, such Lender and the Swingline Lender
(including, but not limited to, any holder of any of the Guarantied Obligations)
in whose favor the provisions of this Guaranty also shall inure, and each
reference herein to each Guarantor shall be deemed to include such Guarantor's

Obligations, or grant or sell participations in any Guarantied Obligations, to
any Person without the consent of, or notice to, any Guarantor and without
releasing, discharging or modifying any Guarantor's obligations hereunder. Each
Guarantor hereby consents to the delivery by the Agent, the Lenders or the
Swingline Lender to any Assignee or Participant (or any prospective Assignee or
Participant) of any financial or other information regarding any Guarantor to
the extent permitted by and in accordance with the Credit Agreement, including,
without limitation, the confidentiality provisions therein. A Guarantor may not
assign or transfer its obligations hereunder to any Person.

         SECTION 22. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE
GUARANTORS HEREUNDER SHALL BE JOINT AND SEVERAL AND ACCORDINGLY, EACH GUARANTOR
CONFIRMS THAT IT IS LIABLE FOR THE FULL AMOUNT OF THE "GUARANTEED OBLIGATIONS"
AND ALL OF THE OBLIGATIONS AND LIABILITIES OF EACH OF THE OTHER GUARANTORS
HEREUNDER.

         SECTION 23. AMENDMENTS. This Guaranty may not be amended, and the

         WHEREAS, the Junior Creditor has extended certain financial

         WHEREAS, it is a condition precedent to the Lenders' continued

         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:

         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 Creditor shall have not received a notice from the Agent
that an Event of Default under and as defined in the Credit Agreement has
occurred and is continuing, the Debtor may pay, and the Creditor may receive,
regularly scheduled payments of interest and principal on the Subordinated 


                                      I-1
<PAGE>   133

         Section 2. 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 Agent 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 Agent) 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.

         Section 3. Bankruptcy of Debtor. In the event of any Bankruptcy
Proceeding, the Junior Creditor will, at the request of the Agent, 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 Agent and assign, transfer and pay over to the Agent,
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 take such action requested by the
Agent, the Agent 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 Agent 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 Agent's own name or in the name of the Junior
Creditor as the Agent may deem necessary or advisable for the enforcement of
this Agreement. The Junior Creditor will execute and deliver to the Agent such
other and further powers of attorney or other instruments as the Agent may
request in order to accomplish the foregoing. The Junior Creditor further grants
to the Agent 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 4. Warranties and Representations of the Junior Creditor. The
Junior Creditor represents and warrants to the Agent, the Lenders and the
Swingline Lender that: (a) no part of the Subordinated Debt is evidenced by any
instrument other than the Subordinated Note; (b) 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 5. Covenants. For so long as this Agreement is in effect the

other writing evidencing any part of the Subordinated Debt other than the

                                      I-2

provision of the Subordinated Note without the prior written consent of the
Agent or (c) 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 6. 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 Agent in the form received (together with any endorsement
necessary to effect a transfer of all rights therein to the Agent) for
application to the Senior Debt. The Junior Creditor irrevocably authorizes the
Agent 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 Agent and shall not be commingled with other
funds or property of the Junior Creditor.

         Section 7. Waivers. To the fullest extent permitted by law, the Junior
Creditor each hereby waives the right to require the Agent, any Lender or the
Swingline Lender to marshal any assets, or to enforce any security interest or
lien the Agent 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 Agent's entitlement to receive any payment on
account of the Subordinated Debt. The Agent, the Lenders and the Swingline
Lender each 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 8. Validity of Subordinated Debt. This Agreement defines the
relative rights of the Junior Creditor, the Agent, the Lenders and the Swingline
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 9. Specific Performance. In addition to any other remedies
available to the Agent, any Lender or the Swingline 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 Agent may, on its behalf
or on behalf of the Lenders and the Swingline Lender, 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 



                                      I-3
<PAGE>   135


defense or dilatory plea this Agreement and the Agent is irrevocably authorized
to intervene and to interpose such defense or plea in the Debtor's name.

         Section 10. Indulgences Not Waivers. Neither the failure nor any delay
on the part of the Agent, any Lender or the Swingline 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 11. Duration. This Agreement shall become effective when

when so accepted, shall constitute a continuing agreement of subordination, and

permit any such Issuer to amend or modify its articles or certificate of
incorporation in a manner which would affect the voting, liquidation, preference

                  (i)  each 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 such 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) each 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,

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


                                      L-4
<PAGE>   147

         (b)      Upon the occurrence and during the continuation of an Event of
Default, all rights of such Pledgor to exercise the voting and/or consensual
rights and powers which such Pledgor is entitled to exercise pursuant to
subsection (a)(i) above and/or to receive the dividends which such 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 such Pledgor shall otherwise be entitled to exercise pursuant
to subsection (a)(i) above and/or to receive and retain the dividends which such
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 such Pledgor shall receive any
dividends or other property which it is not entitled to receive under this
Section, such Pledgor shall hold the same in trust for the Pledgee, without
commingling the same with other funds or property of or held by such Pledgor,
and shall promptly deliver the same to the Pledgee upon receipt by such 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)      Any Pledgor shall fail to observe or perform any covenant or
agreement contained in Sections 4(a), 5, or 7(b) hereof;

         (b)      Any 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 such Pledgor by the Pledgee; and

         (c)      an Event of Default under and as defined in the Credit
Agreement 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 




                                      L-5
<PAGE>   148


purchaser at any sale of Pledged Collateral shall take and hold the property
sold absolutely free from any claim or right on the part of any Pledgor, and
each Pledgor hereby waives (to the fullest extent permitted by Applicable Law)
all rights of redemption, stay and/or appraisal which such Pledgor now has or
may at any time in the future have under any Applicable Law now existing or
hereafter enacted. Each Pledgor agrees that, to the extent notice of sale shall
be required by Applicable Law, at least ten days' prior written notice to such
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 any 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 any 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 such 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 such 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 no Pledgor shall 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. Each 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.

         (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 as provided for under the applicable provisions of the Credit
Agreement. Each 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. Each Pledgor hereby
constitutes and appoints the Pledgee as the attorney-in-fact of such 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 such
Pledgor to do any of the following: (a) to perform any obligation of such
Pledgor hereunder in such 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 such
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 such 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 such 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 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 any 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. Each 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, 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 such 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. Each 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. Each
Pledgor agrees to take, and authorizes the Pledgee to take on such 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 each 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. Each 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 such Pledgor and to sign such Pledgor's name thereto. Each Pledgor authorizes
the Pledgee to file any such financing statement, document or instrument without
the signature of such 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 accompanied by proper instruments of assignment duly executed by each Pledgor
and by such other instruments or documents as the Pledgee may reasonably
request.

         SECTION 14. SECURITIES ACT. In view of the position of each Pledgor in
relation to the Pledged Collateral, or because of other current or future
circumstances, a question may arise under the Securities Act or any similar
Applicable Law hereafter enacted analogous in purpose or 



                                      L-8
<PAGE>   151


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. Each 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. Each
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. Each 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. Each 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. Each Pledgor agrees to indemnify and hold
the Pledgee, each Lender, the Swingline Lender, any corporation controlling,
controlled by, or under common control with, the Pledgee, a Lender or the
Swingline Lender and any officer, attorney, director, shareholder, agent or
employee of the Pledgee, a Lender or the Swingline Lender 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 (each an "Indemnified Claim"), 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, no Pledgor
shall be obligated to indemnify or hold harmless an Indemnified Person for an
Indemnified Claim to the extent that such Indemnified Claim resulted from the
gross negligence or willful misconduct of such Indemnified Person. Each
Pledgor's obligations under this section shall survive the termination of this
Pledge Agreement and the payment in full of the Secured Obligations.

<PAGE>   152


         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. Each 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 such 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,
any Lender or the Swingline Lender to exercise, nor the delay on its part in
exercising any right, power or remedy hereunder, nor any course of dealing
between the Pledgee, any Lender or any Swingline Lender, on the one hand and
such Pledgor on the other hand 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 or Guaranty, as applicable (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 each 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.

         SECTION 21. BINDING AGREEMENT; ASSIGNMENT. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns, except that no Pledgor shall be permitted to
assign this Pledge Agreement or any interest herein or in the Pledged
Collateral, or any part thereof, or any cash or property held by the Pledgee as
collateral under this Pledge Agreement.

         SECTION 22. TERMINATION. Upon indefeasible payment in full of all of
the Secured Obligations, this Pledge Agreement shall terminate. Upon termination
of this Pledge Agreement in accordance with its terms the Pledgee agrees to take
such actions as any Pledgor may reasonably request, and at the sole cost and
expense of such Pledgor, (a) to return the Pledged Collateral to such Pledgor,
and (b) to evidence the termination of this Pledge Agreement, including, without
limitation, the filing of any releases or any termination statements under the
Uniform Commercial Code.

<PAGE>   153


         SECTION 23. SEVERABILITY. Whenever possible, each provision of this
Pledge Agreement shall be interpreted in such a manner as to be effective and
valid under applicable law, but if any provision of this Pledge 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 Pledge Agreement.

         SECTION 24. HEADINGS. Section headings used herein are for convenience
only and are not to affect the construction of or be taken into consideration in
interpreting this Pledge Agreement.

         SECTION 25. COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which shall be deemed an original and all of which
shall constitute but one agreement.

         SECTION 26. EXPENSES. Each Pledgor will pay, within 10 days of demand,
all reasonable fees and expenses actually incurred by the Pledgee in connection
with (a) the collection or enforcement of the Obligations including the
reasonable fees and disbursements of counsel to the Pledgee actually incurred by
the Pledgee and (b) the exercise by the Pledgee 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 27. DEFINITIONS. Terms not otherwise defined herein are used
herein with the respective meanings given to them in the Credit Agreement.

         SECTION 28. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE
PLEDGORS HEREUNDER SHALL BE JOINT AND SEVERAL, AND ACCORDINGLY, EACH PLEDGOR
CONFIRMS THAT IT IS LIABLE FOR ALL OF THE OBLIGATIONS AND LIABILITIES OF THE
OTHER PLEDGORS HEREUNDER.

         SECTION 29. AMENDMENT, RESTATEMENT AND CONSOLIDATION. PRIOR TO THE DATE
HEREOF, CERTAIN OF THE PLEDGORS EXECUTED AND DELIVERED PLEDGE AGREEMENTS IN
FAVOR OF NATIONSBANK IN CONNECTION WITH THE EXISTING CREDIT AGREEMENT (THE
"EXISTING PLEDGE AGREEMENTS"). SUCH PLEDGORS AND THE PLEDGEE ARE ENTERING INTO
THIS PLEDGE AGREEMENT SOLELY TO AMEND, RESTATE AND CONSOLIDATE IN THEIR ENTIRETY
THE TERMS OF, AND THE OBLIGATIONS OWING UNDER AND IN CONNECTION WITH, THE
EXISTING PLEDGE AGREEMENTS. THE PARTIES DO NOT INTEND THIS PLEDGE AGREEMENT NOR

TRANSACTIONS CONTEMPLATED HEREBY SHALL NOT BE DEEMED OR CONSTRUED TO BE, A
NOVATION OF ANY OF THE OBLIGATIONS OWING BY ANY SUCH PLEDGOR UNDER OR IN
CONNECTION WITH ANY OF THE EXISTING PLEDGE AGREEMENTS. FURTHER, THE PARTIES DO
NOT INTEND THIS PLEDGE AGREEMENT NOR THE TRANSACTIONS CONTEMPLATED HEREBY TO
AFFECT THE PERFECTION OR

          FORM OF AMENDED, RESTATED AND CONSOLIDATED SECURITY AGREEMENT


         THIS AMENDED, RESTATED AND CONSOLIDATED SECURITY AGREEMENT is dated as
of July 31, 1998 (this "Security Agreement"), and executed and delivered by each
of the undersigned "Debtors" and the other Persons from time to time party
hereto pursuant to the execution and delivery of an Accession Agreement in the
form of Exhibit A to the Credit Agreement (as defined below) (all of such
undersigned, together with such other Persons each an "Debtor" and collectively,
the "Debtors"), in favor of NATIONSBANK, N.A., successor to NationsBank, N.A.
(South), as Agent (the "Secured Party").

         WHEREAS, Physicians' Specialty Corp. (the "Borrower"), the financial
institutions initially party thereto and their assignees under Section 12.6
thereof (the "Lenders") and the Secured Party have entered into that certain
Amended and Restated Credit Agreement dated as of the date hereof (as the same
may be amended, supplemented, restated or otherwise modified from time to time,
the "Credit Agreement") pursuant to which the Lenders and the Swingline Lender
have agreed to extend certain financial accommodations to the Borrower subject
to the terms thereof;

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

         WHEREAS, the Borrower, the other Debtors and the other Subsidiaries of
the Borrower, though separate legal entities, are mutually dependent on each

        WHEREAS, each Debtor other than the Borrower acknowledges that it will

         (b)      Each Debtor shall, at its sole cost and expense, take all
action that may be necessary or desirable, or that the Secured Party may
request, so as at all times to maintain the validity, perfection, enforceability
and priority of the Security Interest in the Collateral in conformity with the
requirements of Section 3(a), or to enable the Secured Party to exercise or
enforce its rights hereunder including, without limitation:

                  (i)      Paying all taxes, assessments and other claims
         lawfully levied or assessed on any of the Collateral, except to the
         extent that such taxes, assessments and other claims constitute
         Permitted Liens;

                  (ii)     Delivering to the Secured Party, endorsed or
         accompanied by such instruments of assignment as the Secured Party 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 Collateral;

                  (iii)    At the request of the Secured Party, marking
         conspicuously each document included in the Collateral and marking all
         chattel paper and each of its records pertaining to the Collateral,
         with a legend, in form and substance satisfactory to the Secured Party,
         indicating that such document, chattel paper, or Collateral is subject
         to the Security Interest; and

                  (iv)     Executing and delivering financing statements,
         pledges, designations, hypothecations, notices and assignments, in each
         case in form and substance satisfactory to the Secured Party, relating

         Security Interest under the Uniform Commercial Code or other Applicable
         Law.

         (c)      The Secured Party is hereby authorized to execute and file in
all necessary and appropriate jurisdictions (as determined by the Secured Party)
one or more financing or continuation statements (or any other document or
instrument referred to in Section 3(b)(iv) above) in the name of each Debtor and
to sign each Debtor's name thereto. Each Debtor authorizes the Secured Party to
file any such financing statement, document or instrument without the signature
of such 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 financing statement.

         (d)      Each 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 Secured Party shall have the right at any
time and from time to time, in its name in the name of a 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
in favor of a Debtor, such Debtor will immediately thereafter deliver such
instrument to the Secured Party, appropriately endorsed to the Secured Party.

         (c)      Defense of Title. Each Debtor shall at all times be the sole
owner, sole lessee or licensee, as applicable, of each and every item of its
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. Each Debtor shall maintain all
physical property that constitutes its Collateral in good and workable
condition, with reasonable allowance for wear and tear, and shall exercise
proper custody over all such property.

         (e)      Insurance. Each Debtor shall maintain, or cause to be
maintained, such insurance, if any, as may be required under Section 7.5 of the
Credit Agreement.

         (f)      Location of Office. Each 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 on Schedule 2(c) of
this Security Agreement or on Schedule I of the Accession Agreement by which
such Debtor became a party to this Agreement and such Debtor will not change the
location of such office and place of business or such books and records without
giving the Secured Party at least 30 days' prior written notice thereof.

         (g)      Change of Name, Structure, Etc. Without giving the Secured
Party at least 30 days' prior written notice, no Debtor will (i) change its
name, identity or structure or (ii) conduct business under any trade name or
other fictitious name other than those set forth on Schedule 2(a) hereto or on
Schedule I of the Accession Agreement by which such Debtor became a party to
this Agreement.

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

         (i)      Inspection. The Secured Party (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 a 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 such Debtor's affairs and finances, insofar as the same are
reasonably related to the rights of the Secured Party hereunder with any Person,
to verify the amount, quantity, value and condition of, 




                                      M-4
<PAGE>   161


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. Each Debtor shall furnish to the Secured
Party such other information with respect to the Collateral as the Secured Party
may reasonably request from time to time.

         (k)      Payments Directly to Secured Party. The Secured Party may at
any time and from time to time after the occurrence and during continuation of a
Default or Event of Default notify, or request any 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 Secured Party or any agent or
designee of the Secured Party directly, at such address as may be specified by
the Secured Party. If, notwithstanding the giving of any notice, any account
debtor or other such obligor shall make payment to a Debtor, such Debtor shall
hold all such payments it receives in trust for the Secured Party, without
commingling the same with other funds or property of or held by such Debtor, and
shall promptly deliver the same to the Secured Party or any such agent or
designee immediately upon receipt by such 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, no Debtor shall 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 be deemed a
consent by the Secured Party, any Lender or the Swingline Lender to any other
sale or other disposition of any part or all of the Collateral.

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

         SECTION 5. THE SECURED PARTY APPOINTED ATTORNEY-IN-FACT. Each Debtor
hereby irrevocably appoints the Secured Party as such Debtor's attorney-in-fact,
with full authority in the place and stead of such Debtor and in the name of
such Debtor or otherwise, from time to time upon the occurrence and during the
continuance of a Default or Event of Default in the Secured Party's discretion
to take any action and to execute any instrument or document which the Secured
Party may deem necessary or advisable to accomplish the purposes of this
Security Agreement and to exercise any rights and remedies the Secured Party 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 



                                      M-5
<PAGE>   162


amount and at such time or times as the Secured Party 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 Secured Party may deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
the rights of the Secured Party with respect to any of the Collateral. The
power-of-attorney granted hereby shall be irrevocable and coupled with an
interest.

         SECTION 6. THE SECURED PARTY MAY PERFORM. If a Debtor fails to perform
any agreement contained herein, the Secured Party may, with notice to such
Debtor, itself perform, or cause performance of, such agreement, and the
reasonable expenses of the Secured Party incurred in connection therewith shall
be payable by each Debtor under Section 12 hereof; provided, however, the
Secured Party's failure to give such notice shall not in any way affect the
validity of any action taken by the Secured Party under this Section.

         SECTION 7. THE SECURED PARTY'S DUTIES. The powers conferred on the
Secured Party hereunder are solely to protect its interest in the Collateral and
shall not impose any duty upon the Secured Party 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 Secured Party shall
have no duty as to any Collateral. The Secured Party 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
Secured Party accords its own property; it being understood that the Secured
Party shall be under no obligation to take any necessary steps to preserve
rights against prior parties or any other rights pertaining to any Collateral,
but may do so at its option, and all reasonable expenses incurred in connection
therewith shall be for the sole account of the Debtors and shall be added to the
Obligations.

         SECTION 8. REMEDIES. The Secured Party 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 Secured Party may:

                  (i)      without notice, demand or other process, and without
         payment of any rent or any other charge enter any of a Debtor's
         premises and, without breach of the peace, until the Secured Party
         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 such
         Debtor's equipment; and

                  (ii)     in the exercise of the rights of the Secured Party
         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 any Debtor therein, and each Debtor hereby grants a
         license to the Secured Party for this purpose.

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



                                      M-6
<PAGE>   163


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 Secured Party, for cash, on credit or for future
delivery, and at such price or prices and upon such other terms as the Secured
Party may deem commercially reasonable. Each Debtor agrees that, to the extent
notice of sale shall be required by law, at least ten days' notice to such
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 Secured Party shall not be obligated to
make any sale of Collateral regardless of notice of sale having been given. The
Secured Party 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
Secured Party may bid all or any portion of the Obligations at any such sale.

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

         (d)      Appointment of Receiver. The Secured Party 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 any Debtor and to
exercise such power as the court shall confer upon such receiver.

         (e)      Receivables. The Secured Party shall have the exclusive right
to assert, either directly or on behalf of any Debtor, any and all rights and
claims such Debtor may have under any Receivables as the Secured Party 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 provided in the applicable provisions of the Credit Agreement.
Each 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, a Debtor may receive
any insurance proceeds payable by reason of any damage or destruction of any of
the Collateral. If the Secured Party shall receive any such insurance proceeds
which it is not otherwise entitled to retain, the Secured Party shall promptly
turn over such proceeds to the applicable Debtor or to whomsoever may be legally
entitled thereto.

         SECTION 10. RIGHTS CUMULATIVE. The rights and remedies of the Secured
Party, each Lender and the Swingline Lender under this Security Agreement, the
Credit Agreement and each 



                                      M-7
<PAGE>   164


other document or instrument evidencing or securing the Obligations shall be
cumulative and not exclusive of any rights or remedies which any of them would
otherwise have, including, but not limited to, those rights afforded by the
Uniform Commercial Code and other Applicable Laws. In exercising its respective
rights and remedies the Secured Party, each Lender and the Swingline Lender may
be selective and no failure or delay 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. Each Debtor will pay, within 10 days of demand,
all reasonable fees and expenses actually incurred by the Secured Party in
connection with (a) the collection or enforcement of the Obligations including
the reasonable fees and disbursements of counsel to the Secured Party actually
incurred by the Secured Party and (b) the exercise by the Secured Party 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 any Debtor herefrom
shall in any event be effective unless the same shall be made in accordance with
the applicable provisions of the Credit Agreement.

         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 in the case of the Borrower or the Guaranty in the case of any other
Debtor.

         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 each Debtor, its successors and assigns and (iii) inure the
benefit of the Secured Party, the Lenders and the Swingline Lender, and their
respective successors and assigns. A 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, each Lender and the Swingline Lender 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. INDEMNIFICATION. Each Debtor agrees to indemnify and hold
the Secured Party, each Lender, the Swingline Lender, any corporation
controlling, controlled by, or under 



                                      M-8
<PAGE>   165


common control with, the Secured Party, a Lender or the Swingline Lender and any
officer, attorney, director, shareholder, agent or employee of the Secured
Party, a Lender or the Swingline Lender 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 (each an "Indemnified Claim"), brought against or incurred by
an Indemnified Person, in any manner arising out of or, directly or indirectly,
related to or connected with this Agreement, including without limitation, the
exercise by the Secured Party of any of its rights and remedies under this
Agreement or any other action taken by the Secured Party pursuant to the terms
of this Agreement; provided, however, no Debtor shall be obligated to indemnify
or hold harmless an Indemnified Person for any Indemnified Claim to the extent
that such Indemnified Claim resulted from the gross negligence or willful
misconduct of such Indemnified Person. Each Debtor's obligations under this
section shall survive the termination of this Agreement and the payment in full
of the Obligations.

         SECTION 17. COUNTERPARTS. This Security 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 18. DEFINITIONS. (a) For the purposes of this Security
Agreement:

                  Manager to, correct, within 60 days of receipt of written
                  notice, any such deficiencies and provide Plan written notice

execution by Providers of all Participation Agreements. Plan shall have the
right to determine acceptance of all Otolaryngologists, and shall notify Company
upon acceptance or rejection by Plan of any Otolaryngologist.

another agreement, and to the extent the other agreement directly conflicts with
the Participation Agreement, the Participation Agreement shall supersede and
replace the other agreement, but only for the provision of Otolaryngology
services to Members.

If this Agreement terminates, Company's participation under the Participation
Agreement shall also terminate, and, payment to Providers for Health Services
rendered to Capitated Members shall then be paid by Payor pursuant to Appendix B
of the Participation Agreement.

2.5  SERVICE AREA AND AVAILABILITY OF HEALTH SERVICES.

         1.       Company shall assure that Providers' offices are distributed
                  throughout Plan's Service Area, in a manner acceptable to Plan
                  and in locations which are reasonably accessible to all
                  Members. Company shall identify to Plan all office locations
                  and all types of health care professionals providing health
                  care services under the direction of Providers at each
                  location. Company shall provide 30 days prior written
                  notification to Plan of any changes in Provider office
                  locations or types of health care professionals.

         2.       Plan may require Company to establish new office locations and
                  increase the number of Providers upon 60 days prior written
                  notice if (1) Plan decides the then-current locations and
                  Providers are not adequate for the then-current Service Area;
                  or (2) the then-current Service Area is expanded. However,
                  Company shall establish such new office locations and increase
                  the number of Providers within the above time frame as long
                  as, within the first 30 days after receiving such notice from
                  Plan, Company determines it is economically feasible to do so.

         3.       If Company determines it is not economically feasible for
                  Company to establish such new locations and Providers due to
                  2.5.2(1), Company shall immediately notify Plan, at which time
                  the Exclusivity provision set forth in this Agreement, with
                  respect to the then-current Service Area, shall be cancelled,
                  and Plan shall be free to contract directly with the
                  Otolaryngologist in the then-current Service Area.

         4.       If Company determines it is not economically feasible for
                  Company to establish such new locations and Providers due to
                  2.5.2(2), Company shall immediately notify Plan, at which time
                  the Exclusivity provision set forth in this Agreement, with
                  respect to the expanded Service Area, shall be cancelled, and
                  Plan shall be free to contract directly with the
                  Otolaryngologist in the expanded Service Area.

2.6 EXCLUSIVITY. During the term of this Agreement, Plan shall not enter into an
agreement, for the provision of Health Services to Members, with any other
health care providers or networks of providers that specialize in Otolaryngology
and that are located in the Service Area, as modified from time to time by Plan.
This provision shall be in force beginning on the Effective Date and shall
continue to be in force until one of the following occurs: (1) one party gives
notice to the other party of its intent to terminate this Agreement; or (2) in
Plan's judgment and in accordance with Section 2.5, Company can not, for
whatever reason, provide or arrange for adequate access for Members.

2.7 PAYMENT TO PROVIDERS. Company shall be solely responsible for compensating
Providers for all Health Services rendered to Members, and Company and Providers
shall hold harmless and indemnify Plan and Payor against any claims for
compensation by a Provider for Health Services. The method and amount of
compensation to Provider shall be set forth in the Participation Agreement.

                          OBLIGATIONS OF PLAN OR PAYOR

3.1 PAYMENT TO COMPANY. On or before the 15th day of each month, Plan, on behalf
of Payor, shall pay Company for its services and for the provision of Health
Services rendered to Members by Providers, a per Member per month payment, as
set forth below ("Capitation Payment"). The Capitation Payment shall be
calculated based on the total number of Members for which payment of Health
Services is provided under this Agreement. The obligation for payment to Company
under this Agreement is solely that of Payor. Upon reasonable request by
Company, Plan shall provide Company with certain demographic information
relating to Members.


                                      [*]


3.2 ADJUSTMENTS TO CAPITATION PAYMENTS. Any adjustments to the Capitation
Payment shall be reflected in the subsequent month's calculations. Such
adjustments shall be made as deemed necessary by Plan, based solely on the
difference between the actual number of Members and the estimated numbers of
Members.

3.3 LIMITATION OF LOSS. Within 120 days after the end of each Contract Year,
Plan shall determine what the cost of Health Services rendered to each Member by
Providers would have been if paid for on a fee schedule basis for that Contract
Year, using information from claims submitted, including a reasonable estimate
for incurred but not reported claims. The fee schedules will be determined by
Plan and, as of the Effective Date, shall be the then-current fee schedules for
Plan's HMO commercial ("Non-Medicare") and Medicare Benefit Contracts in the
Service Area, net of any Copayments and Deductibles and any withhold that would
have applied to such fee schedule payments.

         1.       Non-Medicare. Payor will reimburse Company [*] of all such
                  costs which would have exceeded [*] for any one
                  Non-Medicare Member. In addition, based on

filed with the Commission.



                  information maintained by Plan and information provided by
                  Company, Plan will calculate the amounts paid to Company for
                  Non-Medicare Members, pursuant to section 3.1 and compare that
                  amount to [*] of the commercial fee schedule for that Contract
                  Year. If the amounts paid to Company are less than [*] of the
                  commercial fee schedule, net of any Copayments and Deductibles
                  and any withhold that would have applied to such fee schedule
                  payments, Company will be paid the difference. Payments to
                  Company pursuant to this section will be made within 30 days
                  after the amounts to be paid are determined by Plan.

         2.       Medicare. Payor will reimburse Company [*] of all such costs
                  which would have exceeded [*] for any one Medicare Member. In
                  addition, based on information maintained by Plan and
                  information provided by Company, Plan will calculate the
                  amounts paid to Company for Medicare Members, pursuant to
                  section 3.1 and compare that amount to [*] of the United
                  HealthCare Medicare fee schedule for that Contract Year. If
                  the amounts paid to Company are less than [*] of the United
                  HealthCare Medicare fee schedule, net of any Copayments and
                  Deductibles and any withhold that would have applied to such
                  fee schedule payments, Company will be paid the difference.
                  Payments to Company pursuant to this section will be made
                  within 30 days after the amounts to be paid are determined by
                  Plan.

3.4 RISK CORRIDOR FOR NON-PARTICIPATING PROVIDER SERVICES. Within 120 days after
the end of each Contract Year, Plan shall determine the total amounts paid to
non-Participating Providers who are Otolaryngologists in the Service Area, for
Health Services rendered to Open Access Members ("Out-of-Network Costs") during
the preceding Contract Year. Plan shall compare the total Capitation Payments
paid to Company for Open Access Members, as defined above, to the total
Out-of-Network Costs. Company shall reimburse Plan any amounts which exceed [*]
of the total Capitation Payments for Open Access Members, up to a maximum of
[*] of the total Capitation Payments for Open Access Members. Such amounts are
payable 30 days after Company receives notice from Plan of the amount due.

3.5 RECOVERIES FROM COORDINATION OF BENEFITS OR SUBROGATION. Plan or Payor will
retain 100% of any amounts recovered by Plan or Payor due to coordination of
benefits or subrogation. Except where otherwise required by Plan's COB rules,
Company or Provider shall retain 100% of any amounts collected by Provider due
to Copayments and Deductibles.

3.6 CLAIMS CONTACT PERSON. Upon request by Company, Plan shall provide Company
with the names of Plan contact persons who are assigned to Company to handle
specific types of questions regarding payment to Providers of claims for health
care services.

3.7 MEMBER PROTECTION PROVISION. The following shall apply when the Member is
covered under Benefit Contract sponsored or issued by a health maintenance
organization, including Plan and United HealthCare of Alabama, Inc. - FQ, and in
all other instances where required by applicable statutes and regulations:

Company hereby agrees that in no event, including, but not limited to,
non-payment, insolvency of Payor, or breach of this Agreement, shall Company
bill, charge, collect a deposit from, seek compensation, remuneration or
reimbursement from, or have any recourse against any Member or persons other
than Payor acting on behalf of the Member for Health Services provided pursuant
to this Agreement. This provision shall not prohibit collection of Copayments or
Deductibles on Payor's behalf, made in accordance with the terms of the Member's
Benefit Contract.

Company further agrees that (a) this provision shall survive the termination of
this Agreement regardless of the cause giving rise to termination and shall be
construed to be for the benefit of the Members; and (b) this provision
supersedes any oral or written contrary agreement, now existing or thereafter
entered into, between Company and a Member or person acting on a Member's
behalf.

Company may not change, amend or waive any provision of this contract without
the prior written consent of Plan. Any attempts to change, amend, or waive this
contract are void.

authority and discretion in its reasonable business judgment to reallocate cost
and expense line items within the budget, so long as the pre-tax income targets
within such budgets are not adversely impacted and Manager's staffing
obligations under Sections 3.8, 3.9 and 3.10 are not materially adversely
affected.

                  (c)      Manager agrees that expenses of the Practice which
are shared by any other practices which are managed by Manager in Cleveland,
Ohio shall be allocated as "Clinic Expenses" to Practice and such other

         covered by such policy or policies pursuant to the Physician Employment
         Agreement;

                  (vii)    maintain Physician's board-certified or board
         eligible status in Physician's practice specialties;

                  (viii)   qualify and maintain Physician's qualification as a
         participating provider in the Medicare and State of Ohio Medicaid
         programs;

                  (ix)     abide by the Principles of Medical Ethics of the
         American Medical Association, and the ethical principles or statements
         as adopted and amended from time to time by the American Board of
         Otolaryngology;

                  (x)      comply with all laws applicable to the conduct of
         Physician's activities, as well as with the articles of incorporation,
         bylaws and other corporate governance documents of Practice and other
         rules or regulations adopted from time to time by Practice;

                  (xi)     promptly disclose to Practice (i) the commencement or
         pendency of any legal action, administrative proceeding or
         investigation, medical staff or professional disciplinary actions
         against Physician or (ii) the existence of any circumstances that could
         reasonably be expected to form the basis of or lead to any such action,
         proceeding or investigation;

                  (xii)    abide by any guidelines adopted by Practice or any
         person or entity providing management services to Practice designed to
         encourage the appropriate, efficient and cost-effective delivery of
         medical services, subject always to the clinical judgment of Physician,
         and cooperate with and participate in all Practice programs regarding
         quality assurance, utilization review, risk management and peer review;

                  (xiii)   maintain appropriate and accurate medical records in
         accordance with accepted medical standards and Practice policies with
         respect to all patients evaluated and treated; and

                  (xiv)    satisfy such other reasonable requirements as are
         established from time to time by Practice.

         4.3      PROVIDER AND PAYOR RELATIONSHIPS. Manager, upon request of
Practice, shall consult with Practice on matters relating to the establishment
or maintenance of relationships with institutional healthcare providers and
third-party payors, including, but not limited to, managed care programs, health
maintenance organizations and preferred provider organizations. Practice shall
not be required by Manager to sign up or contract with any particular provider
or payor.

         4.4      PHYSICIAN POWERS OF ATTORNEY. Practice shall require all
Physician Shareholders and physician Practice Employees to execute and deliver

         4.5      RESTRICTIVE COVENANTS.

                  (a)      Practice acknowledges and agrees that the services to
be provided by Manager hereunder are feasible only if Practice operates a
vigorous medical practice to which its Physician Shareholders and Practice
Employees devote their full time and attention. Accordingly, Practice agrees
that, during the term of this Agreement, it shall not, without the prior written
consent of Manager, establish, operate or provide physician services at any
medical office, clinic or other health care facility providing services
substantially similar to those offered by the Clinic. Practice shall cause its
Physician Shareholders and physician Practice Employees to enter into written
agreements, satisfactory in form and substance to Manager, pursuant to which
Physician Shareholders and physician Practice Employees shall agree not to
establish, operate or provide physician services, without the prior written
consent of Manager, at any medical office, clinic or other health care facility
providing services substantially similar to those provided by the Clinic during
the term of this Agreement. If such person shall cease to be a Physician
Shareholder or physician Practice Employee during the term of this Agreement,
for a period of eighteen (18) months following the termination of the
professional relationship between such person and Practice such person shall
agree not to establish, operate, or provide physician services, without the
prior written consent of Manager, at any medical office, clinic or other health
care facility providing services substantially similar to those provided by the
Clinic within Cleveland, Ohio or any location within a ten (10) mile radius of
the Medical Offices. Manager shall be expressly named as a third-party
beneficiary to such agreements between Practice and each Physician Shareholder
and physician Practice Employee. Notwithstanding the foregoing, the Advisory
Board may waive the restrictive covenant set forth in this Section 4.5(a) as it
applies to any individual physician who ceases to be a Physician Shareholder or
physician Practice Employee.

                  (b)      During the term of this Agreement and for a period of
eighteen (18) months following the termination or expiration of this Agreement,
Practice shall not, without the prior written consent of Manager, employ, hire
or contract for services with any employee or former employee of Manager, nor
shall Practice solicit any such person to leave the employ of Manager. For
purposes of this Section 4.5(b), a "former employee" shall be any person who was
employed by Manager within six (6) months prior to the termination or expiration
of this Agreement. Practice shall cause its Physician Shareholders and physician
Practice Employees to enter into written agreements, satisfactory in form and
substance to Manager, pursuant to which such persons shall agree to be bound by
the same restrictions as set forth in this Section 4.5(b) with respect to
Practice, and Manager shall be expressly named as a third-party beneficiary to
such agreements between Practice and each Physician Shareholder and physician
Practice Employee. This Section 4.5(b) shall not apply to the individuals set
forth on Schedule 4.5(b).

                  (c)      If this Agreement is terminated by Manager pursuant
to Sections 6.2(a) hereof, Practice shall not, for a period of eighteen (18)
months following the effective date of such termination, engage or contract with
any person, firm or entity (or group of affiliated entities) for the provision
of comprehensive management services to the Clinic of the kind contemplated by
this Agreement.



                                       15
<PAGE>   20

                  (d)      Manager and Practice acknowledge and agree that
Manager's remedy at law for any breach or attempted breach of the foregoing
provisions will be inadequate and that Manager shall be entitled to specific
performance, injunction or other equitable relief in the event of any such
breach or attempted breach, in addition to any other remedies which might be
available at law or in equity. If the duration, scope or geographic area
contemplated by the foregoing provisions is determined to be unenforceable by a
court of competent jurisdiction, the parties agree that such duration, scope or
geographic area shall be deemed to be reduced to the greatest scope, duration or
geographic area which would be enforceable.

                  (e)      If the equitable relief contemplated by the foregoing
paragraph is not available for any reason, or if any court of competent
jurisdiction shall refuse to enforce the foregoing paragraph for reasons of
public policy or otherwise, the parties agree that Manager shall be entitled to
receive liquidated damages from the breaching party in an amount equal to two
times the then-current Practice Compensation (as hereinafter defined), or, in
the event of a breach by a Physician Shareholder or physician Practice Employee,
two times the breaching person's aliquot share of the then-current Practice
Compensation. The parties acknowledge and agree that such liquidated damages are
appropriate because actual damages to Manager would be speculative and difficult
to determine at the time of any such breach.

         4.6      PROFESSIONAL DUES AND EDUCATION EXPENSES. Practice and its
Physician Shareholders and Practice Employees shall be solely responsible for
all costs and expenses associated with membership in professional associations
and continuing professional education. Practice shall ensure that each of its
Physician Shareholders and Practice Employees participates in such continuing
medical education activities as are necessary for such physicians to remain
current in their respective specialties, including, but not limited to, the
minimum continuing medical education requirements imposed by applicable laws and
policies of applicable specialty boards.

         4.7      COOPERATION. Practice shall, and shall cause its Physician
Shareholders and Practice Employees to, exercise diligence in assisting Manager
in keeping costs and expenses of the Clinic to a minimum without sacrificing
professional standards or high quality patient care. Practice shall exercise due
care to ensure that, when being used by Physician Shareholders and Practice
Employees, medical equipment of the Clinic is being used in a safe and efficient
manner, and shall timely report any unsafe or unsatisfactory medical equipment
of which Practice, or any of its Physician Shareholders or Practice Employees,
is aware. Practice acknowledges and agrees that on execution of this Agreement,
Manager will implement its own policies and procedures, including, but not
limited to, policies and procedures regarding cash management and revenue
controls. These policies and procedures will be implemented as soon as
reasonably practicable after execution of this Agreement and may be revised or
amended by Manager from time to time thereafter during the term of this
Agreement. Practice agrees to



                                       16
<PAGE>   21

cooperate with any such implementation, revision, or amendment of Manager's
policies and procedures. Practice also agrees to cooperate with, and participate
in, any patient satisfaction surveys and/or outcomes management surveys or
programs instituted or implemented by Manager.

         4.8      CORPORATION AND EMPLOYMENT AGREEMENTS. Practice represents
that it has delivered to Manager a true and correct copy of the Close
Corporation Agreement and Physician Employment Agreements between Practice and
its Physician Shareholders and will cause all new shareholders of Practice to
execute such agreements prior to becoming a shareholder (or employee) in
Practice. Practice shall not amend the Close Corporation Agreement so as to
cause the Close Corporation Agreement to contravene or conflict with this
Agreement and shall not amend the Physician Employment Agreements between
Practice and its physician employees. Practice shall not waive any material
rights thereunder without the prior consent of Manager. The shareholders of the
Practice are and shall be individual physicians.

SECTION 5.        PRACTICE COMPENSATION.

         5.1      COMPENSATION TO MANAGER. As compensation for services rendered
in connection with the Clinic ("Manager Compensation"), Manager shall receive
compensation determined as set forth on Appendix A, attached hereto and made a
part hereof, which amends, restates and replaces Appendix A in the Prior
Agreement. Practice hereby releases MAC, MPI, Manager and Parent, and their
respective successors and assigns, from any obligation to pay compensation under
Part 2 of Appendix A of the Prior Agreement. Manager shall be entitled, on a
monthly basis, to pay itself from Net Clinic Revenues the amount specified in
Section 5.1 and Appendix A as Manager Compensation for providing its services
under this Agreement. Practice acknowledges and agrees that the amount to be
retained by Manager as Manager Compensation in accordance with this Agreement is
reasonable and fair, given the undertakings of Manager as set forth in this
Agreement and the other benefits and value that accrue to Practice as a result
of Manager's services under this Agreement.

         5.2      PAYMENT OF CLINIC EXPENSES. Manager shall pay all Clinic
Expenses, as they fall due, out of Net Clinic Revenues; provided, however, that
Manager may, in the name of and on behalf of Practice, contest in good faith any
claimed Clinic Expenses as to which there is any dispute regarding the nature,
existence or validity of such claimed Clinic Expenses.

         5.3      DRAWS.

                  (a)      Following the end of each month, Manager shall make
an estimate of the collection percentage ("Estimated Collection Percentage") for
such month's gross production. The Estimated Collection Percentage may vary
depending on historical collection percentages, changes in fee schedules,
changes in third party reimbursement, bad debt write-offs and similar
adjustments. The Estimated Collection Percentage will then be applied to such
month's gross production, resulting in estimated Net Clinic Revenues for such
month. Clinic Expenses will



                                       17
<PAGE>   22

then be subtracted from estimated Net Clinic Revenues, resulting in estimated
Pre-Distribution Margin for such month. Draws attributable to such month are
determined by applying the formula discussed under Section 5.1 and Appendix A to
the estimated Pre-Distribution Margin. Manager shall pay Practice such amount by
the 15th day of the following month.

                  (b)      Practice and Manager mutually recognize and
acknowledge that it is the intent of the parties that all management fees paid
to Manager under this Agreement be reasonable and approximate Manager's actual
costs and expenses plus a reasonable profit. Payment of the management fee is
not intended to be, and shall not be, interpreted or applied as permitting the
Manager to share in Practice's fees for professional services rendered, but is
acknowledged as the parties' negotiated agreement as to the reasonable, fair
market value of the management services being furnished by the Manager pursuant
to this Agreement, considering the nature and volume of such services.

         5.4      DETERMINATION AND PAYMENT OF PRACTICE COMPENSATION.

                  (a)      Within one hundred eighty (180) days after the end of
each calendar year, Manager will adjust the Estimated Collection Percentage
based on actual net cash collections attributable to the gross production for
such year, and shall determine actual Net Clinic Revenues and actual
Pre-Distribution Margin. Within forty-five (45) days after the end of such one
hundred eighty (180) day period, Manager shall cause a payment to be made to
Practice in the following amount, as determined from the financial statements
prepared by Manager pursuant to Section 3.7: Practice shall be paid an amount
equal to the aggregate Practice Compensation payable with respect to such
calendar year, less the aggregate sum of all draws by Practice pursuant to
Section 5.3 during such period. All Pre-Distribution Margin in excess of
Practice Compensation shall be the sole property of Manager.

                  (b)      In the event that, after making the calculation
contemplated by Section 5.4(a), it is determined that draws by Practice under
Section 5.3 for the applicable calendar year exceed the amount which Practice is
ultimately entitled to receive with respect to such year (an "overdraft"),
Practice shall pay the amount of such overdraft to Manager within thirty (30)
days after receipt by Practice of written notice from Manager specifying the
amount of such overdraft or, at the option of Practice, Practice shall have the
amounts payable to it pursuant to Section 5.1 with respect to the next
succeeding four months reduced pro rata by the amount of such overdraft. In the
event Practice disagrees with Manager's computation of Net Clinic Revenues,
Pre-Distribution Margin or Practice Compensation, it shall have the right to
review, upon reasonable notice to Manager, the books and records, and other
documents used in determining such amounts.

         5.5      ASSIGNMENT OF FEES FOR MEDICAL SERVICES.

                  (a)      The parties acknowledge and agree that the
compensation and benefits payable to Practice pursuant to Section 5.1 are
intended to be in lieu of charges which Practice or 



                                       18
<PAGE>   23

its Physician Shareholders or Practice Employees would otherwise earn for the
provision of medical services to patients of their medical practice and which
Practice or the Physician Shareholders or Practice Employees would otherwise
bill and retain for their own account. Accordingly, Practice hereby irrevocably
assigns and sets over to Manager all of its rights to receive payment for such
services and retain such payment for its own account, and shall obtain a like
assignment from all Physician Shareholders and Practice Employees; provided,
that in the case of revenue and accounts receivable generated as a result of
billing for services under Medicare or Medicaid such assignment shall only be an
assignment of proceeds of accounts receivable consistent with the provisions of
applicable law. Except as otherwise provided in Section 3.5(e) and the Billing
Agreement, Practice shall endorse (and shall cause each Physician Shareholder or
Practice Employee to endorse) any payments received on account of such services
to the order of Manager and shall take such other actions as may be necessary to
confirm to Manager the rights set forth in this Section 5.5(a).

                  (b)      Without limiting the generality of the foregoing, it
is the intent of the parties that the assignment to Manager of the rights
described in Section 5.5(a) above shall be inclusive of the rights of Practice
and the Physician Shareholders and Practice Employees to receive payment with
respect to any services rendered prior to the effective date of any expiration
or termination of this Agreement. Practice agrees and shall cause each Physician
Shareholder and Practice Employee to agree, that Manager shall retain the right
to collect and retain for its own account any accounts receivable relating to
any such services rendered prior to the effective date of any such expiration or
termination ("Pre-Termination Accounts Receivable"), and that the proceeds
thereof will be transferred to Manager's account to be applied in accordance
with Section 3.5 and 3.6 and the other provisions of this Agreement and the
Billing Agreement.

                  (c)      Practice acknowledges that it is the intent of
Manager and Parent to grant a security interest in the Pre-Termination Accounts
Receivable to the lender(s) under its working capital credit facility (whether
one or more, "Credit Facility Lender"), as in effect from time to time. Practice
agrees that such security interest of the Credit Facility Lender is intended to
be a first priority security interest and is superior to any right, title or
interest which may be asserted by Practice or any Physician Shareholder or
Practice Employee with respect to Pre-Termination Accounts Receivable or the
proceeds thereof. Practice further agrees, and shall cause each Physician
Shareholder and Practice Employee to agree, that, upon the occurrence of an
event which, under the terms of such working capital credit facility, would
allow the Credit Facility Lender to exercise its right to collect
Pre-Termination Accounts Receivable and apply the proceeds thereof toward
amounts due under such working capital credit facility, the Credit Facility
Lender will succeed to all rights and powers of Manager under the powers of
attorney provided for in Sections 3.6 and 4.4 above as if such Credit Facility
Lender had been named as the attorney-in-fact therein.

                  (d)      If, contrary to the mutual intent of Manager and
Practice, the assignment of rights described in this Section 5.5 shall be
deemed, for any reason, to be ineffective as an outright assignment, then
Practice and each Physician Shareholder and Practice Employee shall, effective
as of the date of this Agreement, be deemed to have granted (and Practice does
hereby



                                       19
<PAGE>   24

grant, and shall cause each Physician Shareholder and Practice Employee to
grant) to Manager a first priority lien on and security interest in and to any
and all interests of Practice and such Physician Shareholders and Practice
Employees in any accounts receivable generated by the medical practice of
Practice and its Physician Shareholders and Practice Employees or otherwise
generated through the operations of the Clinic, and all proceeds with respect
thereto, to secure the payment to Manager of all Net Clinic Revenues in excess
of Practice Compensation, and this Agreement shall be deemed to be a security
agreement to the extent necessary to give effect to the foregoing. Practice
shall execute and deliver, and cause each Physician Shareholder and Practice
Employee to execute and deliver, all such financing statements as Manager may
request in order to perfect such security interest. Practice shall not grant
(and shall not suffer any Physician Shareholder or Practice Employee to grant)
any other lien on or security interest in or to such accounts receivable or any
proceeds thereof.


SECTION 6.        TERM AND TERMINATION.

         6.1      TERM. The term of this Agreement shall continue from the
Effective Date and end on July 30, 2036. Thereafter, this Agreement may be
extended for separate and successive five-year periods (each such five-year
period referred to hereinafter as an "extended term"), under such terms and
conditions as stated herein with respect to any such extended term; provided,
however, that: (a) Practice and Manager mutually agree to extend the term hereof
and mutually agree upon the documents to be in effect during any such extended
term hereto, not less than sixty (60) days prior to expiration of the initial
term or extended term then in effect; and (b) Practice is not in material
default hereunder on the date of commencement of the extended term.

         6.2      TERMINATION.

                  (a)      Manager may terminate this Agreement, and have no
further liability or obligation hereunder, upon the occurrence of one or more of
the following events:

                           (i)      Practice ceases to materially perform its
material duties and responsibilities hereunder or materially breaches any
material term or condition of this Agreement, and such cessation or breach
continues uncured for a period of sixty (60) days (or such longer period as is
reasonably necessary to cure if such cessation or breach is of such a nature
that it cannot be cured within such sixty (60) day period and if Practice
commences the cure within such sixty (60) day period and diligently prosecutes
such cure to completion) after Practice's receipt of written notice specifying
such breach; provided, however, that if Practice or any Physician Shareholder or
Practice Employee breaches Section 4.5 hereof, Manager may terminate this
Agreement immediately upon written notice to Practice.

                           (ii)     Practice voluntarily files a petition in
bankruptcy or makes an assignment for the benefit of creditors or otherwise
seeks relief from creditors under any federal



                                       20
<PAGE>   25

or state bankruptcy, insolvency, reorganization or moratorium statute, or
Practice is the subject of an involuntary petition in bankruptcy which is not
set aside within sixty (60) days of its filing.

                           (iii)    Practice materially breaches or defaults
under any other written agreement with Manager, subject to any applicable notice
and cure periods provided in any such agreement.

                           (iv)     The representations and warranties made by
Practice in this Agreement cease to be true and correct.

                           (v)      If the license of any Physician Shareholder
or physician Practice Employee to practice medicine in the State of Ohio is
suspended or revoked, or he is subjected to any final disciplinary action by the
Ohio State Board of Medicine or any similar body on any grounds, other than
minor, immaterial or insubstantial grounds, or he dies or becomes mentally or
physically disabled and, by reason of such disability, is in the reasonable
judgment of Manager unable to conduct his medical practice on substantially the
same basis as it was conducted prior to such disability, or if any Physician
Shareholder retires or sells his interest in Practice and ceases to practice
medicine on substantially a full-time basis as a Practice Employee; provided,
however, that in any such event Practice shall have one hundred eighty (180)
days from the date on which Manager gives Practice written notice of its intent
to terminate this Agreement pursuant to this Section 6.2(a)(v) to replace the
affected physician with another physician satisfactory to Manager, in its
reasonable discretion; provided further, however, that Manager and Practice may
agree to bring in a locum tenens to provide physician services during such one
hundred eighty (180) day period.

                  (b)      Practice may terminate this Agreement, and have no
further liability hereunder, upon the occurrence of one or more of the following
events:

                           (i)      Manager ceases to materially perform its
material duties and responsibilities hereunder or materially breaches any term
or condition of this Agreement, and such cessation or breach continues uncured
for a period of sixty (60) days (or such longer period as is reasonably
necessary to cure if such cessation or breach is of such a nature that it cannot
be cured within such sixty (60) day period and if Practice commences the cure
within such sixty (60) day period and diligently prosecutes such cure to
completion) after Manager's receipt of written notice specifying such breach.

                           (ii)     Manager voluntarily files a petition in
bankruptcy or makes an assignment for the benefit of creditors or otherwise
seeks relief from creditors under federal or state bankruptcy, insolvency,
reorganization or moratorium statute, or Manager is the subject of an
involuntary petition in bankruptcy which is not set aside within sixty (60) days
of its filing.





                                       21
<PAGE>   26

                           (iii)    Manager fails to remit to Practice the
balance of the Pre-Distribution Margin minus Manager Compensation when due and
payable hereunder and such failure continues uncured for a period of ten (10)
days after Manager's receipt of written notice from Practice specifying such
failure.

         6.3      DUTIES AND REMEDIES UPON EXPIRATION OR TERMINATION. Upon the
expiration or earlier termination of this Agreement, neither party shall have
any further obligation hereunder with the exception of: (a) obligations accruing
prior to the date of such expiration or earlier termination; and (b)
obligations, promises and covenants contained herein which are expressly
provided to extend beyond the term hereof, including, without limitation, any
indemnities, restrictive covenants, and access to books and records. Upon the
expiration or earlier termination of this Agreement, Manager Compensation shall
be prorated between the parties to reflect any partial calendar year. Manager
shall disburse funds for such payment on the closing date of the repurchase of
assets provided for in Section 6.5. If this Agreement is terminated pursuant to
Sections 6.2(a)(i), 6.2(a)(iii), 6.2(b)(i) or 6.2(b)(iii) hereof, the
non-breaching party may pursue such other legal or equitable relief as may be
available in addition to such proration. From and after any termination, each
party shall provide the other with reasonable access to books and records then
owned by it to permit such requesting party to satisfy reporting and contractual
obligations which may be required of it.

         6.4      REPURCHASE OF ASSETS.

                  (a)      Upon the expiration, or earlier termination by either
Practice or Manager (other than termination pursuant to Section 6.2(b)), of this
Agreement, Practice shall:

                           (i)      Purchase from Manager the accounts
receivable of the Clinic at the closing under Section 6.5 at an amount equal to
the net realizable value of the accounts receivable as determined in accordance
with GAAP;

                           (ii)     Purchase from Manager the FFE, all then
unused supplies and inventory, and other tangible and intangible personal
property, located at the Medical Offices or purchased for specific use for the
Clinic (except pharmaceutical supplies), for cash in an amount equal to the book
value thereof as reflected by Manager's books and records of account.
Notwithstanding any provision in this Agreement to the contrary, nothing in this
Agreement is intended, nor should it be construed, to give Practice any right to
acquire any proprietary software of Manager (including software licensed by
Manager from others) used by Manager in its provision of the Management
Services;

                           (iii)    Purchase from Manager any real estate owned
by Manager and associated with the Clinic, and acquired through the Asset
Purchase Agreement or with the Approval of the Advisory Board, at the greater of
(i) the appraised fair market value thereof, or (ii) the then book value thereof
as reflected by Manager's books and records of account. In the event of any
repurchase of such real property, the appraised fair market value shall be
determined 



                                       22
<PAGE>   27

by each of Manager and Practice selecting a duly qualified appraiser, who will
then select a third appraiser. This third appraiser shall perform the appraisal,
which appraisal shall be binding on Manager and Practice. If either party fails
to select an appraiser within fifteen (15) days of the selection of an appraiser
by the other party, the appraiser selected by the other party shall make the
selection of the third-party appraiser;

                           (iv)     Purchase from Manager all improvements,
additions and leasehold improvements, which were acquired through the Asset
Purchase Agreement or with the approval of the Advisory Board, and which relate
primarily to the operation of the Clinic, at book value as reflected by
Manager's books and records of account;

                           (v)      Purchase from Manager the service agreement
costs and any other intangible assets of Manager primarily relating to the
operation of the Clinic (other than those intangible assets accounted for in
Section 6.4(a)(ii)), including goodwill, at book value as if purchase accounting
were used to record the transaction, which transaction includes, without
limitation this Agreement and the Asset Purchase Agreement, and as adjusted
through the last day of the month most recently ended prior to the date of such
expiration or earlier termination, in accordance with GAAP to reflect the
amortization or depreciation of restrictive covenants and intangibles, including
goodwill; and

                           (vi)     Assume all debt and all payables, leases and
other contracts entered into or assumed in connection with and primarily related
to the operation of the Clinic, on such terms and conditions of such obligations
and instruments, such assumption to be accomplished by execution and delivery of
an assumption agreement, in form reasonably satisfactory to Manager and
Practice.

In the event that Practice is unable for any reason to fulfill its obligations
and requirements set forth in this Section 6.4(a) or Section 6.5 below, then the
undersigned Physician Shareholders shall fulfill such obligations and duties as
if such Physician Shareholders were the primary obligors hereunder.

                  (b)      Upon termination of this Agreement by Practice
pursuant to Section 6.2(b) Practice shall:

                           (i)      Purchase from Manager the accounts
receivable of the Clinic at the closing under Section 6.5 at an amount equal to
the net realizable value of the accounts receivable as determined in accordance
with GAAP;

                           (ii)     Purchase from Manager the FFE, all then

Notwithstanding any provision in this Agreement to the contrary, nothing in this
Agreement is intended, nor should it be construed, to give Practice any right to
acquire any proprietary software of Manager (including software licensed by
Manager from others) used by Manager in its provision of the Management
Services;

                           (iii)    Purchase from Manager any real estate owned
by Manager and associated with the Clinic, and acquired through the Asset
Purchase Agreement or with the Approval of the Advisory Board, at the greater of
(i) the appraised fair market value thereof, or (ii) the then book value thereof
as reflected by Manager's books and records of account. In the event of any
repurchase of such real property, the appraised fair market value shall be
determined by each of Manager and Practice selecting a duly qualified appraiser,
who will then select a third appraiser. This third appraiser shall perform the
appraisal, which appraisal shall be binding on Manager and Practice. If either
party fails to select an appraiser within fifteen (15) days of the selection of
an appraiser by the other party, the appraiser selected by the other party shall
make the selection of the third-party appraiser;

                           (iv)     Purchase from Manager all improvements,
additions and leasehold improvements, which were acquired through the Asset
Purchase Agreement or with the approval of the Advisory Board, and which relate
primarily to the operation of the Clinic, at book value as reflected by
Manager's books and records of account;

                           (v)      Assume all debt and all payables, leases and
other contracts entered into or assumed in connection with and primarily related
to the operation of the Clinic, on such terms and conditions of such obligations
and instruments, such assumption to be accomplished by execution and delivery of
an assumption agreement, in form reasonably satisfactory to Manager and
Practice.

In the event that Practice is unable for any reason to fulfill its obligations
and requirements set forth in this Section 6.4(b) or Section 6.5 below, then the
undersigned Physician Shareholders shall fulfill such obligations and duties as
if such Physician Shareholders were the primary obligors hereunder.

         6.5      CLOSING OF REPURCHASE OF ASSETS. Practice shall pay cash for
the repurchased assets, as contemplated by Section 6.4. The amount of the
purchase price shall be reduced by the amount of debt and liabilities (other
than contingent liabilities, such as leases) of Manager assumed by Practice and
shall also be reduced by any payment Manager has failed to make under this
Agreement. Practice, Physician Shareholders and physician Practice Employees
shall execute such documents as may be required to assume the liabilities set
forth in Section 6.4(a)(vi) or 6.4(b)(v) and to remove Manager and Parent from
any liability or guaranty with respect to such repurchased assets and with
respect to any property leased or subleased by Manager. The closing date for the
repurchase shall be determined by the parties hereto, but in no event shall
occur later than ninety (90) days from the date of termination or the notice of
termination, as applicable.

SECTION 9.        ASSIGNMENT.

         The parties hereby agree that this Agreement shall not be assigned or

other; provided, however, that this Agreement may be assigned by Manager, in its
sole discretion, without the consent of Practice, to any parent, subsidiary or
affiliate of Manager or to any person or entity that acquires all or
substantially all of the assets of Manager or Parent. Notwithstanding the
foregoing, the Practice agrees and consents to the Manager granting to the
Credit Facility Lender a security interest in all of the Manager's right, title
and interest in and under this Agreement as security for the Manager's
obligations under a guaranty of all of the Parent's indebtedness and other
obligations owing to the Credit Facility Lender.


SECTION 10.       COMPLIANCE WITH REGULATIONS.

         10.1     PRACTICE OF MEDICINE. The parties hereto acknowledge that
Manager is not authorized or qualified to engage in any activity which may be
construed or deemed to constitute the practice of medicine. To the extent any
act or service herein required of Manager should be construed or deemed to
constitute the practice of medicine, the performance of said act or service by
Manager shall be deemed waived and forever unenforceable. The Practice shall
have unfettered control in the exercise of its professional medical judgment
with respect to medical matters.

         10.2     SUBCONTRACTS. Pursuant to Title 42 of the United States Code
and applicable rules and regulations thereunder, until the expiration of four
(4) years after termination of this Agreement, Manager shall make available,
upon appropriate written request by the Secretary of the United States
Department of Health and Human Services or the Comptroller General of the United
States General Accounting Office, or any of their duly authorized
representatives, a copy of this Agreement and such books, documents and records
as are necessary to certify the nature and extent of the costs of the services
provided by Manager under this Agreement. Manager further agrees that if it
carries out any of its duties under this Agreement through a subcontract with a
value or cost of Ten Thousand and No/100 Dollars ($10,000.00) or more over a
twelve (12) month period with a related organization, such subcontract shall
contain a clause to the effect that until the expiration of four (4) years after
the furnishing of such services pursuant to such subcontract, the related
organization shall make available, upon appropriate written request by the
Secretary of the United States Department of Health and Human Services or the
Comptroller General of the United States General Accounting Office, or any of
their duly authorized representatives, a copy of such subcontract and such
books, documents and records of such



                                       27
<PAGE>   32

organization as are necessary to verify the nature and extent of such costs.
Disclosure pursuant to this Section shall not be construed as a waiver of any
other legal right to which Manager may be entitled under law or regulation.


SECTION 11.       INDEPENDENT RELATIONSHIP.

         11.1     INDEPENDENT CONTRACTOR STATUS.

                  (a)      It is acknowledged and agreed that Practice and
Manager are at all times acting and performing hereunder as independent
contractors. Manager shall neither have nor exercise any control or direction
over the methods by which Practice, Physician Shareholders and Practice
Employees practice medicine. The sole function of Manager hereunder is to
provide all Management Services in a competent, efficient and satisfactory
manner. Manager shall not, by entering into and performing its obligations under
this Agreement, become liable for any of the existing obligations, liabilities
or debts of Practice unless otherwise specifically provided for under the terms
of this Agreement. In its management role, Manager will have only an obligation
to exercise reasonable care in the performance of the Management Services.
Manager shall have no liability whatsoever for damages suffered on account of
the willful misconduct or negligence of any employee, agent or independent
contractor of Practice. Each party shall be solely responsible for compliance
with all state and federal laws pertaining to employment taxes, income
withholding, unemployment compensation contributions and other employment
related statutes regarding their respective employees, agents and servants.

                  (b)      If any court or regulatory authority shall determine
that the independent contractor relationship established hereby violates any
statutes, rules or regulations (or in the event that Manager, in good faith,
determines that there is a material risk that such a determination would be made
by any court or regulatory authority), then, at the request of Manager given by
written notice to Practice, the parties will negotiate in good faith to enter
into an employment arrangement between Manager and the then-current Physician
Shareholders and Practice Employees which substantially preserves for the
parties the relative economic benefits of this Agreement. If the parties cannot
reach agreement on such an arrangement after a period of 30 days of good faith
negotiations which shall commence after the aforesaid determination or opinion
is delivered, then either Practice or Manager may elect by notice to the other
to require that the parties enter into binding mediation in accordance with this
Section 11.1(b) to determine such arrangement. Pursuant to any such notice of
mediation Manager and Practice shall each choose an expert possessing knowledge
regarding health care management arrangements in the State of Ohio, and the two
experts so chosen shall select a third expert (the "Mediator") who shall be a
lawyer or accountant with a nationally recognized firm possessing knowledge and
experience regarding health care management arrangements in the State of Ohio.
Following selection the Mediator shall meet with Manager and Practice and, if
the parties are still unable to agree after two (2) such meetings, the Mediator
shall propose in a writing labeled "Binding



                                       28
<PAGE>   33

Arrangement" an arrangement which best complies with statutes, rules and
regulations and which substantially preserves for the parties the relative
economic benefits of this Agreement, and such proposed binding arrangement shall
be final and binding on the parties. Each party shall bear the costs associated
with the retention of its chosen expert, and the costs associated with the
Mediator shall be paid by Manager in a percentage amount equal to a fraction,
the numerator of which is Manager's annual Manager Compensation for the most
recent fiscal year ended, and the denominator of which is Net Practice Revenues
for such fiscal year. The balance of the Mediator's cost shall be a Practice
Expense.

         11.2     REFERRAL ARRANGEMENTS. The parties hereby acknowledge and
agree that no benefits to Practice hereunder require or are in any way
contingent upon the admission, recommendation, referral or any other arrangement
for the provision of any item or service offered by Manager or any of its
affiliates, to any patients of Practice, Practice's employees, leased employees
or agents.


SECTION 12.       CONFIDENTIAL INFORMATION.

         Except as required to perform its obligations under this Agreement,
Manager shall not, without the express written consent of Practice, distribute,
market, publish, or divulge to any person or entity, or use or modify for use,
directly or indirectly, any "Practice Confidential Information" during the term
of this Agreement and for a period of three (3) years after the final date of
the term of this Agreement; provided, however, that Manager may disclose
Practice Confidential Information, (i) to other medical practices which are
potential acquisition or merger partners for Manager or the Clinic, (ii) as
required by law, governmental order or regulation, or by subpoena or other legal
process (provided Practice will be provided advance notice of such disclosure in
order to afford it the opportunity to seek an appropriate protective order),
(iii) in any litigation involving Practice, Manager or a Physician Shareholder,
and (iv) to Manager's lenders, financial advisors, accountants, investment
bankers, investors, and attorneys. For purposes of this Agreement "Practice
Confidential Information" shall mean valuable, non-public competitively
sensitive data and information relating to Practice that is not generally known
by or readily available to competitors of Practice, including payor and managed
care contract fees and rates under exclusive arrangements of Practice with third
party payors, and Practice revenue and expense reports and related financial
information.

SECTION 13.       GUARANTY BY PARENT.

         To induce Practice to execute and deliver this Agreement, Parent hereby
absolutely and unconditionally guarantees the full, prompt and faithful
performance by Manager of all covenants and obligations to be performed by
Manager under this Agreement, including, but not limited to, the payment of all
sums stipulated to be paid by Manager pursuant to this Agreement. If Manager
fails to fully perform all such covenants and obligations in accordance with
their terms or pay all or any part of such sums when due, Parent will perform
all such covenants and obligations in accordance with their terms or immediately
pay to Practice (or such other payee as



                                       29
<PAGE>   34

may be provided in any such agreement) the amount due and unpaid by Manager, it
being understood that each such covenant or obligation and each obligation to
pay any such amount constitutes the direct and primary obligation of Parent.
Parent hereby waives presentment, demand of payment, protest, dishonor, notice
of protest or dishonor, and notice of acceptance of the guaranty set forth in
this Section 13 and all rights to require Practice to proceed against Manager,
or to pursue any other remedy it may have against Manager in the event of a
breach by Manager of any obligation or covenant contained in this Agreement. If
Manager is not liable to perform any such obligation or covenant because the act
creating such obligation or covenant is ultra vires or unauthorized, and for
such reason such obligation or covenant cannot be enforced against Manager, such
fact shall not affect Parent's liability under this Section 13. In the event of
termination, liquidation or dissolution of Manager, this unconditional guaranty
shall continue in full force and effect.


SECTION 14.       MISCELLANEOUS.

Agreement, prohibit, restrict or in any way materially and adversely change the
method or amount of reimbursement or payment for services rendered by Practice
pursuant to this Agreement or of the method of compensation for either party
provided for in this Agreement, then the Practice and Manager shall each have
the option to request the other that the parties consider negotiating in good
faith to amend this Agreement to provide for payment of compensation in a manner
consistent with any such prohibition, restriction or limitation and which takes
into account any materially adverse change in reimbursement or payment from such
third party payors for such physician services. If the parties cannot reach

or interpretation, this Agreement shall continue in full force and effect in
accordance with its terms.

<PAGE>   36

Agreement may not be changed or terminated orally, but may only be changed by an

reason of that party's role in drafting this Agreement.

         14.9     COUNTERPARTS. This Agreement may be executed in several
counterparts, each of which, when so executed, shall be deemed to be an
original, and such counterparts shall, together, constitute and be one and the

assigns.

         14.11    ENFORCEMENT RIGHTS. Practice acknowledges that both Practice
and Manager will be directly or indirectly affected by the enforcement of
Practice's contractual and other legal rights against Physician Shareholders and
Practice Employees with respect to the restrictive covenants and liquidated

Practice appoints Manager its nonexclusive true and lawful attorney-in-fact to
enforce any and all rights of Practice, to the extent not contrary to applicable
law, with respect to the provisions pertaining to restrictive covenants and
liquidated damages in the Physician Employment Agreements. Practice agrees to
execute any instrument reasonably requested by Manager to evidence such
appointment or to reappoint Manager as such attorney-in-fact upon any
termination of the appointment made hereby. Such appointment is coupled with an
interest and irrevocable during the term of this Agreement.

party" shall mean the party in whose favor final judgment after appeal (if any)
is rendered with respect to the claims asserted in the Complaint. "Reasonable
attorneys' fees" are those attorneys' fees actually incurred in obtaining a

SECTION 15.       PHYSICIANS' GUARANTY.

         To induce Manager and Parent to execute and deliver this Agreement,
each of the undersigned Physician Shareholders during the term of his or her
employment with Practice and for a period of five (5) years thereafter, hereby
absolutely and unconditionally guarantees the full, prompt and faithful
performance by Practice of all covenants and obligations to be performed by
Practice under Sections 3.6, 4.4, 4.5, 5.5, 6.4, 6.5, 8.1, 8.3, and 14.7 of this
Agreement. If Practice fails to fully perform all such covenants and obligations
in accordance with their terms or pay all or any part of such sums when due, the
Physician Shareholders will perform all such covenants and obligations in
accordance with their terms or immediately pay to Manager the amount due and
unpaid, it being understood that each such covenant or obligation and each
obligation to pay any such amount constitutes the direct and primary obligation
of the Physician Shareholders. The Physician Shareholders hereby waive
presentment, demand of payment, protest, dishonor, notice of protest or
dishonor, and notice of acceptance of the guaranty set forth in this Section 15
and all rights to require Manager to proceed against Practice, or to pursue any
other remedy it may have against Practice in the event of a breach by Practice
of any obligation or covenant contained in the aforesaid sections of this
Agreement. If Practice is not liable to perform any such obligation or covenant
because the act creating such obligation or covenant is ultra vires or
unauthorized, and for such reason such obligation or covenant cannot be enforced
against Practice, such fact shall not affect the Physician Shareholders'
liability under this Section 15. In the event of termination, liquidation or
dissolution of Practice, this unconditional guaranty shall continue in full
force and effect.

                               BILLING AGREEMENT
                                      for
                            GOVERNMENTAL RECEIVABLES

     THIS BILLING AGREEMENT ("Agreement") is entered into this _____ day of 
___________, 1998, by and between PSC MANAGEMENT CORP., a Delaware corporation 
("Manager"), and CLEVELAND EAR, NOSE AND THROAT CENTER, INC., an Ohio 
corporation, and the Physician Shareholders who are signatories hereto 
(collectively referred to as "Practice").

                                  WITNESSETH:

     WHEREAS, the parties entered into an Amended and Restated Clinic Services
Agreement dated ________ __, 1998 (the "Service Agreement"), under which Manager
provides certain management services to Practice, including billing and
collection services for Medicare, Medicaid and CHAMPUS receivables; and,

     WHEREAS, the parties wish to set forth in detail the mechanisms under 
which Manager provides and is compensated for such billing services.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties agree as follows:

     1.  Appointment and Authority  Manager shall, on behalf of Practice, bill 
and collect from Medicare, Medicaid and CHAMPUS the professional fees for 
medical services rendered by Practice to Medicare, Medicaid and CHAMPUS 
patients. Practice hereby appoints Manager for the term hereof to be Practice's 
true and lawful attorney-in-fact for the following purposes:

         a.  to bill Medicare, Medicaid and CHAMPUS in the name and on behalf of
             Practice;

         b.  to collect all accounts receivable resulting from such billings in
             the name and on behalf of Practice;

         c.  to take possession of and endorse in the name and on behalf of
             Practice (and/or in the name of an individual physician who has
             properly reassigned benefits to Practice) any notes, checks, money
             orders, electronic payments, and other forms of payment of such
             accounts receivable;
<PAGE>   44

         d.  to deposit all such amounts collected, including electronic
             payments, into an account owned by Practice (the "Physician Deposit
             Account") with a bank whose deposits are insured by the Federal
             Deposit Insurance Corporation, which account shall at all times be
             maintained in accordance with the provisions of Section 2 below;
             and,

         e.  to withdraw funds from the Physician Deposit Account in accordance
             with the provisions of Section 2 below on behalf and in the name of
             Practice for the payment of Practice Expenses, and remittance of
             funds to Practice as provided in the Service Agreement.

     2.  Physician Deposit Account.

         a.  Manager shall have access to the Physician Deposit Account solely
             for the purpose of paying Practice Expenses incurred by or on
             behalf of Practice, including the payment of Manager's fee, in
             accordance with the terms of the Service Agreement. Practice agrees
             to execute and deliver to the bank any and all documents necessary
             to evidence or effect the special power of attorney granted to
             Manager in accordance with Section 1 above.

         b.  Medicare and Medicaid payments shall be deposited directly to the
             Physician Deposit Account. Practice and Manager hereby agree that
             if any Medicare and Medicaid payments are received by Manager on
             behalf of Practice, such amounts shall be forwarded to the
             Physician Deposit Account for deposit. Funds from the Physician
             Deposit Account will only be drawn in the name of Practice.
             Practice hereby agrees that this payment arrangement will continue
             in effect only so long as Practice has sole control of the
             Physician Deposit Account, and the bank is subject only to
             Practice's instructions regarding the Physician Deposit Account.

         c.  In the event that Practice revokes Manager's right to withdraw
             funds form the Physician Deposit Account, or if Practice withdraws
             funds from the Physician Deposit Account or takes any other actions
             with respect to the Physician Deposit Account (unless such actions
             are required by applicable law) without first obtaining the
             approval of the Advisory Board in accordance with the Service
             Agreement (it being understood that all proceeds are intended to be
             paid over to Manager to pay Practice Expenses and repay any
             advances made by Manager in accordance with the Service Agreement),
             and if any such actions remain uncured after notice and ten (10)
             days opportunity to cure, such actions shall constitute grounds for
             immediate termination of this Agreement and the Service Agreement
             as a "Practice Event of Default" thereunder, and Practice hereby
             acknowledges that Practice has granted to Manager a security
             interest in Practice's cash

                                       2
<PAGE>   45
             proceeds from all collections covered by this Agreement in
             accordance with Section 5.5 of the Service Agreement. Practice
             further agrees in the event Practice revokes Manager's right to
             withdraw funds from the account that Practice shall be deemed to
             have received any and all amounts retained in the Physician Deposit
             Account when determining the amount to be remitted by Manager to
             Practice under the Service Agreement.

     3.  Compensation.  As reimbursement for services provided under the 
Service Agreement and this Agreement, Manager shall receive the fees set forth 
in Section 5.1 and Appendix A of the Service Agreement. The parties have agreed 
to such fees at arms' length and have determined that such fees represent fair 
market value for the services provided hereunder and under the Service 
Agreement.

     4.  Construction of Terms.  The terms of the Service Agreement shall, to 
the fullest extent reasonably possible, be construed so as to be consistent 
with the terms of this Agreement, and all capitalized terms herein shall, 
except as otherwise expressly provided herein, have the same definitions as set 
forth in the Service Agreement. In the event of any ambiguity or inconsistency 
between the terms and conditions of this Agreement and the Service Agreement, 
the terms and conditions of this Agreement shall govern.

     5.  Changes in Reimbursement Laws and Regulations.  In the event of 
changes in laws and regulations that would cause any portion of this Agreement 
to be illegal or unenforceable, the parties shall promptly amend this Agreement 
as necessary to comply with such laws and regulations.

     6.  Binding on Successors.  This Agreement shall be binding upon the 
parties hereto, and their successors, assigns, heirs and beneficiaries. Without 
limitation of the foregoing, Manager shall have the same rights to assign this 
Agreement as provided in Section 14.10 of the Service Agreement with respect to 
assignment of the Service Agreement.

     7.  Governing Law.  The validity, interpretation, and performance of this 
Agreement shall be governed by the laws designated to govern the terms of the 
Service Agreement.

     8.  Severability.  The provisions of this Agreement shall be deemed 
severable and if any portion shall be held invalid, illegal or unenforceable 
for any reason, the remainder of this Agreement shall be effective and binding 
upon the parties.

     9.  Amendments.  This Agreement shall not be modified or amended except by 
a written document executed by both parties to this Agreement, and any such 
written modifications or amendments shall be attached hereto.
