              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)



1.  BUSINESS AND ORGANIZATION

     Organization

     OrthAlliance, Inc. ("OrthAlliance" or the "Company"), a Delaware
corporation, was founded in October, 1996 to provide practice management and
consulting services (collectively "management services") to orthodontic
practices in the United States. Effective prior to the closing of the initial
public offering (the "Offering" or "IPO"), Premier Orthodontic Group, Inc.
("Premier") and US Orthodontic Care, Inc. ("USOC") merged with and into
OrthAlliance. In the merger, the outstanding common stock of USOC and Premier
converted into shares of Class A Common Stock ("Common Stock") and shares of
Class B Common Stock ("Class B Common Stock"). On August 26, 1997, OrthAlliance
acquired (the "Acquisitions") simultaneously with the closing of the IPO of its
Class A Common Stock certain operating assets of or the stock of entities
holding certain tangible and intangible assets and assumed certain liabilities
of 55 orthodontic practices (collectively, the "Founding Practices") in exchange
for shares of Common Stock and cash. The Acquisitions have been accounted for in
accordance with the Securities and Exchange Commission's Staff Accounting
Bulletin No. 48.

    OrthAlliance has two wholly-owned subsidiaries, PedoAlliance, Inc.
("PedoAlliance") and OrthAlliance Finance, Inc. ("OA Finance"). PedoAlliance was
formed in December 1997 to provide practice management or consulting services to
pediatric dental practices. Unless otherwise indicated, certain references
herein to "Orthodontists" also include Allied Dentists. The Founding Practices
and any practice that affiliated with OrthAlliance or PedoAlliance subsequent to
the Company's IPO, shall be referred to collectively as "Allied Practices." OA
Finance was formed in October 1997 to offer financing alternatives to the
patients of the Allied Practices. OrthAlliance, PedoAlliance and OA Finance are
sometimes collectively referred to as the "Company."

     Basis of Presentation

     The condensed consolidated financial statements included herein have been
prepared by the Company without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission (the "SEC"). Pursuant to such
regulations, certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. The Company believes the presentation
and disclosure herein are adequate to make the information not misleading. The
financial statements reflect all elimination entries and normal adjustments that
are necessary for a fair presentation of the results for the interim period
ended March 31, 1999.

     Operating results for interim periods are not necessarily indicative of the
results for full years. These condensed consolidated financial statements should
be read in conjunction with the Financial Statements of OrthAlliance and related
notes thereto, and management's discussion and analysis related thereto, all of
which are included in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1998, No. 000-22975 (the "Annual Report").

     In the opinion of Company management, the accompanying consolidated
financial statements include the accounts of the Company and all adjustments
necessary to present fairly the Company's financial position at March 31, 1999
and December 31, 1998, and its results of operations and cash flows for the
three months ended March 31, 1999 and March 31, 1998.

     The Company currently does not consolidate the operations of the Allied
Practices that it manages because the Company's arrangement with its Allied
Practices do not meet the requirements for consolidation as set forth in
EITF 97-2.

    Prior year reclassifications

Certain prior year amounts have been reclassified to conform to current year
presentation.


2.  NEW ORTHODONTIST AFFILIATIONS

     From January 1, 1999 to March 31, 1999, the Company entered into agreements
with 11 Allied Practices which included six orthodontists and seven pediatric
dentists to provide management services and acquire certain operating assets for
a total



                                       6
<PAGE>   7


consideration (including acquisition costs) of $10.9 million. This consideration
consisted of 93,584 shares of Common Stock with an aggregated value at various
acquisition costs of $0.8 million and a cash payment of $10.1 million. These
Allied Practices operate 23 locations and generated patient revenue of
approximately $10.0 million during a 12-month period prior to the date of
affiliation. Prior patient revenue is not necessarily indicative of the level of
revenue these practices may be expected to generate in the future.

3.  SUBSEQUENT EVENTS

     New Orthodontic Affiliations

     Subsequent to March 31, 1999, three practices affiliated with the Company,
which included one orthodontist and three pediatric dentists. The Company 
entered into agreements with these practices to provide management services and
to acquire certain operating assets for a total consideration (including
acquisition costs) of $2.2 million, paid in cash. The Allied Practices that
affiliated with the Company since March 31, 1999 operate four locations and
generated historical patient revenue over the prior 12 months of approximately
$2.0 million. Prior patient revenue is not necessarily indicative of the level
of revenue that these practices may be expected to generate in the future.

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

     The following discussion and analysis contains certain forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995. These statements are based on current plans and expectations of the
Company and involve risks and uncertainties that could cause actual future
activities and results of operations to be materially different from those set
forth in the forward-looking statements. Important factors that could cause
actual results to differ include, among others, risks associated with
affiliations, fluctuations in operating results because of affiliations and
variations in stock price, changes in government regulations, competition, risks
of operations and growth of existing and newly affiliated orthodontic practices,
and risks detailed in the Company's SEC filings.

General

     The Company began providing practice management services to Allied
Practices in the United States on August 26, 1997. The initial 55 Allied
Practices included 82 Allied Orthodontists operating 147 offices in 16 states.
By the end of 1997, the Company had affiliated with 11 new practices, including
17 additional practitioners operating out of 31 new locations. In 1998, the
Company affiliated with 36 new practices, including 45 additional orthodontists
and pediatric dentists operating out of 70 locations. In the first quarter of
1999, the Company affiliated with 11 new practices, including 13 additional
orthodontists and pediatric dentists operating out of 23 locations. The Company
anticipates that future growth will come from new affiliations, satellite
expansion of Allied Practices, the development of new orthodontic practices and
through improved operating efficiencies.

     The Company earns revenue by providing services pursuant to long-term
service agreements or consulting agreements (collectively, "Management
Agreements") with Allied Practices. The Company provides management or
consulting services to each Allied Practice and assumes substantially all
operating expenses except for compensation to Allied Orthodontists and other
employees that the Company cannot employ according to applicable state laws. In
exchange for assuming these expenses and providing services, the Company records
revenues in amounts equal to the assumed expenses plus a service fee or
consulting fee, as described below. In general, the Management Agreements
provide for the recognition of fees to the Company based on a negotiated
percentage of the "Adjusted Patient Revenue" of Allied Practices. The timing of
the payment of such service fees is based upon cash collected. Adjusted Patient
Revenue is net patient revenue, as determined under generally accepted
accounting principles, including adjustments for contractual allowances and
other discounts, plus an adjustment for uncollectible accounts. Patient revenue
is recognized as services are performed. For orthodontic services, approximately
20% of the orthodontic contract revenue is recognized at the time of initial
treatment. The balance of the contract revenue is realized evenly over the
remaining treatment period. The 20% estimated revenue at the initial treatment
date is based on the estimated costs incurred by the practice at that time as
compared to the total costs of providing the contracted services and is
consistent with industry standards. The percentage includes the estimated costs
of diagnosis and treatment plan development, initial treatment by orthodontic
personnel, orthodontic supplies, and associated administrative services.

     The service fee is earned and paid monthly to the Company by each Allied
Practice using one of three different fee structures set forth in the Management
Agreements:




                                       7
<PAGE>   8


         (i) a designated percentage of Adjusted Patient Revenue, ranging from
     13.5% to 20%, subject to an annual adjustment based upon improvements in
     the Allied Practice's operating margin in the most recent calendar year as
     compared with the immediately preceding calendar year. No annual adjustment
     shall be made which would result in reducing the designated percentage
     below the percentage applicable during the first year of the Management
     Agreement. Operating margin is defined as the percentage determined by
     dividing operating profit by Adjusted Patient Revenue. Operating profit is
     equal to Adjusted Patient Revenue less operating expenses, excluding the
     management fee and such expenses associated with the Allied Practices which
     the Company is prohibited from incurring, primarily consisting of
     orthodontist compensation. The average designated percentage is 16.9% for
     the Allied Practices subject to this fee structure.

         (ii) a designated percentage ranging from 13.5% to 20% of Adjusted
     Patient Revenue with a potential annual adjustment of 25% of the increase
     in operating margin (as defined in subparagraph (i) above) in a calendar
     year as compared to the preceding calendar year multiplied by the Adjusted
     Patient Revenue for the current calendar year. The supplemental fee for
     improvement in operating margin, if applicable, is paid in a lump sum
     payment upon final determination of the Allied Practice's operating margin
     for the calendar year. The average designated percentage is 16.7% for the
     Allied Practices subject to this fee structure. In some cases, the Allied
     Orthodontist must guarantee a minimum level of management fees to be paid
     by the Allied Practice for a portion of the agreement ranging from one to
     25 years.

         (iii) a fixed dollar fee with annual fixed dollar increases for each
     year of the term of the Management Agreement.

     The Company has entered into agreements with certain Allied Practices to
make the payment of management fees after the first two years contingent on
various factors, including practice profitability compared to acquisition
consideration, timely reporting of information, participation in practice
improvement programs and orthodontist hours worked.

     Expenses reported by the Company include certain of the expenses to operate
the orthodontic offices and all of the expenses of any corporate offices,
facilities or functions. Therefore, salaries and benefits include the wages,
benefits, taxes or other employment costs for all employees of the Company,
including practice office staff, business office staff and management personnel.
Rent includes facility expenses for both practice offices and corporate offices.
Advertising and marketing includes practice activities to attract new patients
and corporate activities to attract new orthodontists to join the Company.
General and administrative expenses include professional services, such as legal
and accounting, utilities, advertising, marketing, insurance, telephone, license
fees, office supplies and shipping expenses. Practice supplies include only
those expenses required by the Allied Orthodontist to provide treatment to
patients.

     Net Revenue. Net revenue for the three-month period ended March 31, 1999
was $21.3 million, an increase of 45.4% over the same period in 1998. This was
attributable to the new affiliations of Allied Practices and an increase in
internal growth of the existing



                                       8
<PAGE>   9


Allied Practices. Net Revenue reported by the Company generally includes the
Company's management fee plus reimbursed operating expenses of the Allied
Practices.

     Operating Expenses. Total operating expenses, as a percentage of net
revenue, remained at a consistent percentage of net revenue. The operating
expense categories are consistent with management's expectations.

     Depreciation and Amortization. Depreciation and amortization expense
increased approximately $336,000 or 69.1% for the three months ended March 31,
1999 as compared to the same period in 1998. This increase was attributable to
the increase in intangible assets associated with the affiliations of Allied
Practices. Intangible assets, net, increased $9.5 million from $50.9 million to
$60.4 million from December 31, 1998 to March 31, 1999. Depreciation and
amortization expense primarily relates to the depreciation of capital assets and
the amortization of excess cost over the fair value of net assets acquired and
certain other intangibles. The Company's policy is to amortize goodwill over the
expected period to be benefited, not to exceed the term of the Management
Agreements or other related agreements. For the three months ended March 31,
1999 and 1998, depreciation and amortization were $822,000 and $486,000,
respectively.

     Interest Expense. For the three months ended March 31, 1999 and 1998,
interest expense was $394,000 and $7,000, respectively. This increase is due to
a greater average outstanding principal balance on the Company's revolving line
of credit, for the three months ending March 31, 1999 compared to the three
months ending March 31, 1998. The outstanding balance of this line of credit was
$26.0 million and $15.5 million at March 31, 1999 and December 31, 1998,
respectively. See further discussion in the Liquidity and Capital Resources
section below.

     Provision for Income Taxes. For the three months ended March 31, 1999 and
1998, the provision for income taxes was $1.7 million and $1.3 million,
respectively. The Company's effective income tax rates for the three months
ended March 31, 1999 and 1998, were higher than the statutory tax rate due to
the non-deductibility of the amortization of certain intangible assets.

LIQUIDITY AND CAPITAL RESOURCES

     As of March 31, 1999 and December 31, 1998, the Company had a working
capital balance of approximately $15.8 million and $13.2 million, respectively.
The Company anticipates the primary uses of capital will include additional
affiliations with orthodontic and pediatric dental practices, certain costs
related to the development of satellite offices, and funding the working capital
needs of the Company and Allied Practices.

     On December 30, 1997, the Company entered into a credit agreement with
First Union National Bank to provide a $25 million revolving line of credit.
Management expanded the credit facility on March 26, 1999 from $25 million to
$55 million. The agreement terminates on March 26, 2002. The interest on
borrowings accrues at either the bank's prime rate or LIBOR, plus a margin.
Amounts borrowed are secured by security interests in the Company's assets,
which include accounts receivable, Management Agreements and the capital stock
of the Company's wholly-owned subsidiaries. As of March 31, 1999 and December
31, 1998, the outstanding balance under this credit facility was $26.0 million
and $15.5 million, respectively. As of March 31, 1999, the Company was in
compliance with all applicable covenants.

     The working capital requirements and capital resources needed to continue
acquisition and development efforts will be funded through a combination of cash
flows provided by ongoing operations and from the Company's revolving line of
credit. Management believes that these sources of capital will be sufficient to
meet the Company's funding requirements for the next twelve months. The Company
may choose to issue debt or equity to meet its future long-term capital needs as
management deems appropriate.

     The Management Agreements provide for short-term advances by the Company to
the Allied Practices for working capital requirements and other purposes on
terms to be mutually agreed upon. These items are advanced and repaid in a
revolving manner. Generally, advances are repaid when Allied Practices deposit
patient revenue into their depository accounts. Advances occur when the Allied
Practice operating expenses paid exceeded patient revenue earned.

STOCK REPURCHASE PLAN

On October 22, 1998 the Company announced that the Board of Directors approved
the repurchase of shares of its Common Stock up to $5 million. The Company is
authorized to purchase shares over a 12-month period on Nasdaq Stock Market's
National Market at prices prevailing on that market. As of March 31, 1999, the
Company repurchased 22,500 shares under this Stock Repurchase Plan.

YEAR 2000 COMPLIANCE

     The Year 2000 issue arose as a result of certain computer hardware and
software using two digits rather than four digits to define the applicable year.
As a result, some of the Company's hardware and software systems have
date-sensitive software or embedded chips which may incorrectly recognize a date
using "00" rather than the year 2000 or not recognize the year at all. This
could result in system failures or miscalculations leading to disruptions in the
Company's activities and operations.

Corporate Office

     The Company has performed a comprehensive Year 2000 evaluation of the
hardware and software systems utilized by the corporate office in all areas of
office automation, including payroll, payables, general ledger and data
management. As far as can be determined, all computer network systems are in
full compliance. Necessary certificates of compliance have been obtained from
hardware and software vendors.

     In the event the Company fails to identify all of the systems at risk for
possible failure due to the Year 2000 issue, the Company plans to retain a
complete backup of the systems and data in use prior to December 31, 1999. If,
after the Company begins operations in the Year 2000, it is determined that a
system has failed, the Company can reset all system clocks to a date prior to
January 1, 2000 and restore the affected systems from the copy. This will
provide the Company with more time to repair the affected systems.

     The Company has requested Year 2000 compliance certificates from its
material third parties. The Company received compliance certificates from
approximately 60% of such requests. The Company will verify the status of the
remaining material third parties through follow-up requests. The Company is
uncertain whether the risks of non-Year 2000 compliance by material third
parties will materially affect the Company's operations or financial position.
The Company has determined it is not substantially reliant on any one vendor and
expects to use alternate resources in order to continue daily operations. There
can be no assurance that material third parties will not suffer a Year 2000
business disruption which could have an adverse effect on the Company's results
of operations or financial position.

     The corporate office does not have any "Non-IT" systems that might be
affected by the Year 2000 issue. As an example, the Company does not own any
automated machinery, elevators, telephone switches, or other equipment that
might contain micro-controllers. Therefore, the Company does not believe that it
is at risk from any failure associated with these kinds of devices.

     Because the Company started operations in August 1997, most of the
corporate office systems were already Year 2000 compliant. Accordingly, any
costs associated with Year 2000 upgrades, including fiscal year 1998 and
year-to-date as of May 14, 1999 have not been significant. Additionally, the
Company does not expect to incur any significant costs in the future.

Allied Practice Locations

     The Company has completed a survey of all practice hardware and software to
identify non-compliant systems and to make the necessary recommendations for
achieving compliance. The Company is currently advising the Allied Practices to
install upgrades and replace hardware and software as necessary. The Allied
Practices are contractually responsible to reimburse the Company for any costs
the Company incurs to upgrade its hardware and software, whether owned by
themselves or the Company.

     The Company believes that the significant systems that may impact the
Allied Practice's operations are the practice management and billing system and
the accounts payable system. In the event that the Allied Practices have not
upgraded or replaced their hardware, software or non-IT devices, the Company
believes that the impact on Allied Practice operations would be minimal.

     In the event that these systems are not Year 2000 compliant, certain
procedures can be utilized to minimize the affect on practice operations. These
procedures may include the following: manual billings, manual posting of
payments to patient records and manual preparation of vendor payments. Although
additional staffing may be necessary to perform these tasks without the benefit
of the affected automated systems, these functions are not critical to providing
orthodontic or pediatric dental services.




                                       10
<PAGE>   11

     Additionally, the Company plans to advise the Allied Practice to have a
contingency plan, including a complete backup of all systems and data prior to
December 31, 1999. If the Allied Practices determine that a system has failed
after operations commence in the year 2000, they can reset all system clocks to
a date prior to January 1, 2000 and restore the affected systems from the
backup. This will provide the Allied Practice with more time to repair the
affected systems.

     The Company has advised the Allied Practices to request Year 2000
compliance certificates from their key material third parties. The Company is
uncertain whether the risks of non-Year 2000 compliance by third parties of the
Allied Practices will materially affect the Company's operations or financial
position. The Company has determined that the Allied Practices are not
substantially reliant on any individual third party and expects them to use
alternate resources if necessary to continue daily operations.

     The Company may own some "Non-IT" systems in practice offices that might be
affected by the Year 2000 issue. The Company has not yet determined which
offices may contain such devices. The Company has advised each Allied Practice
to evaluate all equipment to determine if any such devices exist. In the event
that some of the Allied Practices have not upgraded their significant non-IT
systems, such as x-ray and imaging machines, the Allied Practices can outsource
the procedures in order to continue its daily operations. The Allied Practices
are contractually responsible to reimburse the Company for any costs the Company
incurs to repair or replace any non-compliant devices, whether owned by
themselves or the Company.

NEW ACCOUNTING PRONOUNCEMENTS

     Effective January 1, 1998, the Company adopted SFAS 130, "Reporting
Comprehensive Income." This statement establishes disclosure requirements
related to the reporting of comprehensive income and its components. The
Company did not have any comprehensive income for the year ended December 31,
1998 and for the three months ended March 31, 1999.

     Effective January 1, 1998, the Company implemented SFAS 131, "Disclosures
about Segments of an Enterprise and Related Information." This standard
established disclosure requirements related to the reporting of the Company's
operating segments. As of March 31, 1999, the Company does not have any
reportable segments.

     The Emerging Issues Task Force of the Financial Accounting Standards Board
issued its Consensus Opinion 97-2 ("EITF 97-2"), which addresses certain
specific matters pertaining to the physician, dentistry and veterinary practice
management industries. EITF 97-2 became effective for the Company for its year
ending December 31, 1998. EITF 97-2 addresses the ability of certain practice
management companies to consolidate the results of certain practices with which
it has an existing contractual relationship. The Company currently does not
consolidate the operations of the practices that it manages. The guidance in
EITF 97-2 did not change the Company's accounting method because the Company's
arrangements with its Allied Practices do not meet the requirements for
consolidation as set forth in EITF 97-2.

     Effective January 1, 1999, the Company implemented SOP 98-5 "Reporting on
Costs of Start-up Activities." The SOP requires net costs of start-up
activities, including organizational costs, to be expenses as incurred. In
addition, the SOP requires that previously capitalized start-up costs be
expenses upon the effective date. The Company does not have any start-up costs
capitalized as of March 31, 1999.

                                   ARTICLE II.

                          AMOUNT AND TERMS OF THE LOANS

         2.1     Commitments. Each Lender severally agrees, subject to and on
the terms and conditions of this Agreement, to make loans (each, a "Loan," and
collectively, the "Loans") to the Borrower, from time to time on any Business
Day during the period from and including the Closing Date to but not including
the Termination Date, provided that (i) the aggregate principal amount of Loans
at any time outstanding for any Lender shall not exceed such Lender's Commitment
at such time, and (ii) no Borrowing shall be made if, immediately after giving
effect thereto, the sum of the aggregate principal amount of Loans outstanding
at such time would exceed the aggregate Commitments at such time. Subject to and
on the terms and conditions of this Agreement, the Borrower may borrow, repay
and reborrow Loans.

         2.2     Borrowings.

         (a)     The Loans shall, at the option of the Borrower and subject to
the terms and conditions of this Agreement, be either Base Rate Loans or LIBOR
Loans (each, a "Type" of Loan), provided that (i) all Loans comprising the same
Borrowing shall, unless otherwise specifically provided herein, be of the same
Type and (ii) any Loans made on the Closing Date shall be made initially as Base
Rate Loans.

         (b)     In order to make a Borrowing (other than Borrowings involving
continuations or conversions of outstanding Loans, which shall be made pursuant
to SECTION 2.11), the Borrower will give the Agent written notice not later than
12:00 noon, Charlotte time, three (3) Business Days prior to each Borrowing to
be comprised of LIBOR Loans and one (1) Business Day prior to each Borrowing to
be comprised of Base Rate Loans; provided, however, that requests for the
Borrowing of any Loans to be made on the Closing Date may, at the discretion of
the Agent, be given later than the times specified hereinabove. Each such notice
(each, a "Notice of Borrowing") shall be irrevocable, shall be given in the form
of EXHIBIT B-1 and shall specify (1) the aggregate principal amount and initial
Type of the Loans to be made pursuant to such Borrowing, (2) in the case of a
Borrowing of LIBOR Loans, the initial Interest Period to be applicable thereto,






                                       21
<PAGE>   23

and (3) the requested date of such Borrowing (the "Borrowing Date"), which shall
be a Business Day. Upon its receipt of a Notice of Borrowing, the Agent will
promptly notify each Lender of the proposed Borrowing. Notwithstanding anything
to the contrary contained herein:

                   (i) the aggregate principal amount of each Borrowing
         comprised of Base Rate Loans shall not be less than $1,000,000, or, if
         greater, an integral multiple of $100,000 in excess thereof, and the
         aggregate principal amount of each Borrowing comprised of LIBOR Loans
         shall not be less than $3,000,000 or, if greater, an integral multiple
         of $1,000,000 in excess thereof;

                  (ii) if the Borrower shall have failed to designate the Type
         of Loans comprising a Borrowing, the Borrower shall be deemed to have
         requested a Borrowing comprised of Base Rate Loans; and

                 (iii) if the Borrower shall have failed to select the duration
         of the Interest Period to be applicable to any Borrowing of LIBOR
         Loans, then the Borrower shall be deemed to have selected an Interest
         Period with a duration of one month.

         (c) Not later than 1:00 p.m., Charlotte time, on the requested
Borrowing Date, each Lender will make available to the Agent at its office
referred to in SECTION 10.5 (or at such other location as the Agent may
designate) an amount, in Dollars and in immediately available funds, equal to
the amount of the Loan or Loans to be made by such Lender. To the extent the
Lenders have made such amounts available to the Agent as provided hereinabove,
the Agent will make the aggregate of such amounts available to the Borrower in
accordance with SECTION 2.3(A) and in like funds as received by the Agent.

         2.3      Disbursements; Funding Reliance; Domicile of Loans.

         (a) The Borrower hereby authorizes the Agent to disburse the proceeds
of each Borrowing in accordance with the terms of any written instructions from
any of the Authorized Officers, provided that the Agent shall not be obligated
under any circumstances to forward amounts to any account not listed in an
Account Designation Letter. The Borrower may at any time deliver to the Agent an
Account Designation Letter listing any additional accounts or deleting any
accounts listed in a previous Account Designation Letter.

         (b) Unless the Agent has received, prior to 1:00 p.m., Charlotte time,
on the relevant Borrowing Date, written notice from a Lender that such Lender
will not make available to the Agent such Lender's ratable portion, if any, of
the relevant Borrowing, the Agent may assume that such Lender has made such
portion available to the Agent in immediately available funds on such Borrowing
Date in accordance with the applicable provisions of SECTION 2.2, and the Agent
may, in reliance upon such assumption, but shall not be obligated to, make a
corresponding amount available to the Borrower on such Borrowing Date. If and to
the extent that such Lender shall not have made such portion available to the
Agent, and the Agent shall have made such corresponding amount available to the
Borrower, such Lender, on the one hand, and the Borrower, on the other,
severally agree to pay to the Agent forthwith on demand such corresponding
amount, together with interest thereon for each day from the date such amount is





                                       22
<PAGE>   24

made available to the Borrower until the date such amount is repaid to the
Agent, (i) in the case of such Lender, at the Federal Funds Rate, and (ii) in
the case of the Borrower, at the rate of interest applicable at such time to the
Type of Loan comprising such Borrowing, as determined under the provisions of
SECTION 2.8. If such Lender shall repay to the Agent such corresponding amount,
such amount shall constitute such Lender's Loan as part of such Borrowing for
purposes of this Agreement. The failure of any Lender to make any Loan required
to be made by it as part of any Borrowing shall not relieve any other Lender of
its obligation, if any, hereunder to make its Loan as part of such Borrowing,
but no Lender shall be responsible for the failure of any other Lender to make
the Loan to be made by such other Lender as part of any Borrowing.

         (c) Each Lender may, at its option, make and maintain any Loan at, to
or for the account of any of its Lending Offices, provided that any exercise of
such option shall not affect the obligation of the Borrower to repay such Loan
to or for the account of such Lender in accordance with the terms of this
Agreement.

         2.4      Notes.

         (a) The Loans made by each Lender shall be evidenced by a Note
appropriately completed in substantially the form of EXHIBIT A.

         (b) Each Note issued to a Lender with a Commitment shall (i) be
executed by the Borrower, (ii) be payable to the order of such Lender, (iii) be
dated as of the Closing Date, (iv) be in a stated principal amount equal to such
Lender's Commitment, (v) bear interest in accordance with the provisions of
SECTION 2.8, as the same may be applicable from time to time to the Loans made
by such Lender, and (vi) be entitled to all of the benefits of this Agreement
and the other Credit Documents and subject to the provisions hereof and thereof.

         (c) Each Lender will record on its internal records the amount and Type
of each Loan made by it and each payment received by it in respect thereof and
will, in the event of any transfer of any of its Notes, either endorse on the
reverse side thereof or on a schedule attached thereto (or any continuation
thereof) the outstanding principal amount and Type of the Loans evidenced
thereby as of the date of transfer or provide such information on a schedule to
the Assignment and Acceptance relating to such transfer; provided, however, that
the failure of any Lender to make any such recordation or provide any such
information, or any error therein, shall not affect the Borrower's obligations
under this Agreement or the Notes.

         2.5      Termination and Reduction of Commitments.

         (a) The Commitments shall be automatically and permanently terminated
on the Termination Date (or on April 15, 1999, but only if the Closing Date
shall not have occurred on or prior to such date).

         (b) At any time and from time to time, upon at least five (5) Business
Days' prior written notice to the Agent, the Borrower may terminate in whole or
reduce in part the aggregate Unutilized Commitments, provided that any such
partial reduction shall be in an aggregate amount of not less than $1,000,000 or
integral multiples thereof. The amount of any such termination or reduction made
under this subparagraph (b) shall be applied ratably to the Commitments and may
not thereafter be reinstated.






                                       23
<PAGE>   25

         2.6      Mandatory Payments and Prepayments.

         (a) Except to the extent due or paid sooner pursuant to the provisions
of this Agreement, the aggregate outstanding principal of the Loans shall be due
and payable in full on the Maturity Date.

         (b) In the event that, at any time, the aggregate principal amount of
Loans outstanding at such time shall exceed the aggregate Commitments at such
time, the Borrower will immediately prepay the outstanding principal amount of
the Loans in the amount of such excess.

         (c) Each payment or prepayment of a LIBOR Loan made pursuant to the
provisions of this Section on a day other than the last day of the Interest
Period applicable thereto shall be made together with all amounts required under
SECTION 2.18 to be paid as a consequence thereof.

         2.7      Voluntary Prepayments.

         (a) At any time and from time to time, the Borrower shall have the
right to prepay the Loans, in whole or in part, without premium or penalty
(except as provided in clause (iii) below), upon written notice given to the
Agent not later than 12:00 noon, Charlotte time, three (3) Business Days prior
to each intended prepayment of LIBOR Loans and one (1) Business Day prior to
each intended prepayment of Base Rate Loans, provided that (i) each partial
prepayment shall be in an aggregate principal amount of not less than $1,000,000
or, if greater, an integral multiple of $100,000 in excess thereof, (ii) no
partial prepayment of LIBOR Loans made pursuant to any single Borrowing shall
reduce the aggregate outstanding principal amount of the remaining LIBOR Loans
under such Borrowing to less than $3,000,000 or to any greater amount not an
integral multiple of $1,000,000 in excess thereof, and (iii) unless made
together with all amounts required under SECTION 2.18 to be paid as a
consequence of such prepayment, a prepayment of a LIBOR Loan may be made only on
the last day of the Interest Period applicable thereto. Each such notice shall
specify the proposed date of such prepayment and the aggregate principal amount
and Type of the Loans to be prepaid (and, in the case of LIBOR Loans, the
Interest Period of the Borrowing pursuant to which made), and shall be
irrevocable and shall bind the Borrower to make such prepayment on the terms
specified therein. Loans prepaid pursuant to this subsection (a) may be
reborrowed, subject to the terms and conditions of this Agreement.

         (b) Each prepayment of the Loans made pursuant to subsection (a) above
shall be applied ratably among the Lenders holding the Loans being prepaid, in
proportion to the principal amount held by each.

         2.8      Interest.

         (a) The Borrower will pay interest in respect of the unpaid principal
amount of each Loan, from the date of Borrowing thereof until such principal
amount shall be paid in full, (i) at the Adjusted Base Rate applicable to such
Loan, as in effect from time to time during such periods as such Loan is a Base
Rate Loan, and (ii) at the Adjusted LIBOR Rate applicable to such Loan, as in
effect from time to time during such periods as such Loan is a LIBOR Loan.




                                       24
<PAGE>   26

         (b) Upon the occurrence and during the continuance of an Event of
Default as the result of failure by the Borrower to pay any principal of or
interest on any Loan, any fees or other amount hereunder when due (whether at
maturity, pursuant to acceleration or otherwise), and (at the election of the
Required Lenders) upon the occurrence and during the continuance of any other
Event of Default, all outstanding principal amounts of the Loans and, to the
greatest extent permitted by law, all interest accrued on the Loans and all
other accrued and outstanding fees and other amounts hereunder, shall bear
interest at a rate per annum equal to the interest rate applicable from time to
time thereafter to such Loans (whether the Adjusted Base Rate or the Adjusted
LIBOR Rate) plus 2% (or, in the case of fees and other amounts, at the Adjusted
Base Rate plus 2%), and, in each case, such default interest shall be payable on
demand. To the greatest extent permitted by law, interest shall continue to
accrue after the filing by or against the Borrower of any petition seeking any
relief in bankruptcy or under any law pertaining to insolvency or debtor relief.

         (c) Accrued (and theretofore unpaid) interest shall be payable as
follows:

                   (i) in respect of each Base Rate Loan (including any Base
         Rate Loan or portion thereof paid or prepaid pursuant to the provisions
         of SECTION 2.6 OR 2.7, except as provided hereinbelow), in arrears on
         the last Business Day of each calendar quarter, beginning with the
         first such day to occur after the Closing Date; provided, that in the
         event the Loans are repaid or prepaid in full and the Commitments have
         been terminated, then accrued interest in respect of all Base Rate
         Loans shall be payable together with such repayment or prepayment on
         the date thereof;

                  (ii) in respect of each LIBOR Loan (including any LIBOR Loan
         or portion thereof paid or prepaid pursuant to the provisions of
         SECTION 2.6 OR 2.7, except as provided hereinbelow), in arrears on the
         last Business Day of the Interest Period applicable thereto (subject to
         the provisions of clause (iv) in SECTION 2.10); provided, that in the
         event all LIBOR Loans made pursuant to a single Borrowing are repaid or
         prepaid in full, then accrued interest in respect of such LIBOR Loans
         (and all amounts owing pursuant to SECTION 2.18) shall be payable
         together with such repayment or prepayment on the date thereof; and

                 (iii) in respect of any Loan, on the Termination Date and,
         after the Termination Date, on demand.

         (d) Nothing contained in this Agreement or in any other Credit Document
shall be deemed to establish or require the payment of interest to any Lender at
a rate in excess of the maximum rate permitted by applicable law. If the amount
of interest payable for the account of any Lender on any interest payment date
would exceed the maximum amount permitted by applicable law to be charged by
such Lender, the amount of interest payable for its account on such interest
payment date shall be automatically reduced to such maximum permissible amount.
In the event of any such reduction affecting any Lender, if from time to time
thereafter the amount of interest payable for the account of such Lender on any
interest payment date would be less than the maximum amount permitted by
applicable law to be charged by such Lender, then the amount of interest payable
for its account on such subsequent interest payment date shall be automatically
increased to such maximum permissible amount, provided that at no time shall the





                                       25
<PAGE>   27

aggregate amount by which interest paid for the account of any Lender has been
increased pursuant to this sentence exceed the aggregate amount by which
interest paid for its account has theretofore been reduced pursuant to the
previous sentence.

         (e) The Agent shall promptly notify the Borrower and the Lenders upon
determining the interest rate for each Borrowing of LIBOR Loans after its
receipt of the relevant Notice of Borrowing or Notice of
Conversion/Continuation, and upon each change in the Base Rate; provided,
however, that the failure of the Agent to provide the Borrower or the Lenders
with any such notice shall neither affect any obligations of the Borrower or the
Lenders hereunder nor result in any liability on the part of the Agent to the
Borrower or any Lender. Each such determination (including each determination of
the Reserve Requirement) shall, absent manifest error, be conclusive and binding
on all parties hereto.

         2.9      Fees.  The Borrower agrees to pay:

         (a) To First Union, for its own account, on the date of its execution
of this Agreement, the fees described in the Fee Letter, in the amounts set
forth therein as due and payable on such date and to the extent not theretofore
paid to First Union;

         (b) To the Agent, for the account of each Lender, a commitment fee for
each calendar quarter (or portion thereof) for the period from the date of this
Agreement to the Termination Date, at a per annum rate equal to the Applicable
Margin Percentage in effect for such fee from time to time during such quarter,
on such Lender's ratable share (based on the proportion that its Commitment
bears to the aggregate Commitments) of the average daily aggregate Unutilized
Commitments, payable in arrears (i) on the last Business Day of each calendar
quarter, beginning with the first such day to occur after the Closing Date, and
(ii) on the Termination Date;

         (c) To the Agent, for its own account, an annual administrative fee in
the amount and on the terms as may be agreed by the Borrower and the Agent upon
the primary syndication of the Facility.

         2.10 Interest Periods. Concurrently with the giving of a Notice of
Borrowing or Notice of Conversion/Continuation in respect of any Borrowing
comprised of Base Rate Loans to be converted into, or LIBOR Loans to be
continued as, LIBOR Loans, the Borrower shall have the right to elect, pursuant
to such notice, the interest period (each, an "Interest Period") to be
applicable to such LIBOR Loans, which Interest Period shall, at the option of
the Borrower, be a one, two or three-month period; provided, however, that:

                   (i)     all  LIBOR  Loans  comprising  a  single  Borrowing  
shall at all times have the same Interest Period;

                  (ii) the initial Interest Period for any LIBOR Loan shall
         commence on the date of the Borrowing of such LIBOR Loan (including the
         date of any continuation of, or conversion into, such LIBOR Loan), and
         each successive Interest Period applicable to such LIBOR Loan shall
         commence on the day on which the next preceding Interest Period
         applicable thereto expires;




                                       26
<PAGE>   28

                 (iii) LIBOR Loans may not be outstanding under more than five
         (5) separate Interest Periods at any one time (for which purpose
         Interest Periods shall be deemed to be separate even if they are
         coterminous);

                  (iv) if any Interest Period otherwise would expire on a day
         that is not a Business Day, such Interest Period shall expire on the
         next succeeding Business Day unless such next succeeding Business Day
         falls in another calendar month, in which case such Interest Period
         shall expire on the next preceding Business Day;

                   (v) the Borrower may not select any Interest Period that
         begins prior to the Closing Date or that expires after the Maturity
         Date, with respect to Loans that are to be maintained as LIBOR Loans;

                  (vi) if any Interest Period begins on a day for which there is
         no numerically corresponding day in the calendar month during which
         such Interest Period would otherwise expire, such Interest Period shall
         expire on the last Business Day of such calendar month; and

                 (vii) if, upon the expiration of any Interest Period applicable
         to a Borrowing of LIBOR Loans, the Borrower shall have failed to elect
         a new Interest Period to be applicable to such LIBOR Loans, then the
         Borrower shall be deemed to have elected to convert such LIBOR Loans
         into Base Rate Loans as of the expiration of the then current Interest
         Period applicable thereto.

         2.11     Conversions and Continuations.

         (a) The Borrower shall have the right, on any Business Day occurring on
or after the Closing Date, to elect (i) to convert all or a portion of the
outstanding principal amount of any Base Rate Loans into LIBOR Loans, or to
convert any LIBOR Loans the Interest Periods for which end on the same day into
Base Rate Loans, or (ii) to continue all or a portion of the outstanding
principal amount of any LIBOR Loans the Interest Periods for which end on the
same day for an additional Interest Period, provided that (x) any such
conversion of LIBOR Loans into Base Rate Loans shall involve an aggregate
principal amount of not less than $1,000,000 or, if greater, an integral
multiple of $100,000 in excess thereof; any such conversion of Base Rate Loans
into, or continuation of, LIBOR Loans shall involve an aggregate principal
amount of not less than $3,000,000 or, if greater, an integral multiple of
$1,000,000 in excess thereof; and no partial conversion of LIBOR Loans made
pursuant to a single Borrowing shall reduce the outstanding principal amount of
such LIBOR Loans to less than $3,000,000 or to any greater amount not an
integral multiple of $1,000,000 in excess thereof, (y) except as otherwise
provided in SECTION 2.16(D), LIBOR Loans may be converted into Base Rate Loans
only on the last day of the Interest Period applicable thereto (and, in any
event, if a LIBOR Loan is converted into a Base Rate Loan on any day other than
the last day of the Interest Period applicable thereto, the Borrower will pay,
upon such conversion, all amounts required under SECTION 2.18 to be paid as a
consequence thereof), and (z) no conversion of Base Rate Loans into LIBOR Loans
or continuation of LIBOR Loans shall be permitted during the continuance of a
Default or Event of Default.




                                       27
<PAGE>   29

         (b) The Borrower shall make each such election by giving the Agent
written notice not later than 12:00 noon, Charlotte time, three (3) Business
Days prior to the intended effective date of any conversion of Base Rate Loans
into, or continuation of, LIBOR Loans and one (1) Business Day prior to the
intended effective date of any conversion of LIBOR Loans into Base Rate Loans.
Each such notice (each, a "Notice of Conversion/Continuation") shall be
irrevocable, shall be given in the form of EXHIBIT B-2 and shall specify (x) the
date of such conversion or continuation (which shall be a Business Day), (y) in
the case of a conversion into, or a continuation of, LIBOR Loans, the Interest
Period to be applicable thereto, and (z) the aggregate amount and Type of the
Loans being converted or continued. Upon the receipt of a Notice of
Conversion/Continuation, the Agent will promptly notify each Lender of the
proposed conversion or continuation. In the event that the Borrower shall fail
to deliver a Notice of Conversion/Continuation as provided herein with respect
to any outstanding LIBOR Loans, such LIBOR Loans shall automatically be
converted to Base Rate Loans upon the expiration of the then current Interest
Period applicable thereto (unless repaid pursuant to the terms hereof). In the
event the Borrower shall have failed to select in a Notice of
Conversion/Continuation the duration of the Interest Period to be applicable to
any conversion into, or continuation of, LIBOR Loans, then the Borrower shall be
deemed to have selected an Interest Period with a duration of one month.

         2.12     Method of Payments; Computations.

         (a) All payments by the Borrower hereunder shall be made without
setoff, counterclaim or other defense, in Dollars and in immediately available
funds to the Agent, for the account of the Lenders entitled to such payment
(except as otherwise provided herein as to payments required to be made to the
Agent for its own account or directly to the Lenders) at its office referred to
in SECTION 10.5, prior to 12:00 noon, Charlotte time, on the date payment is
due. Any payment made as required hereinabove, but after 12:00 noon, Charlotte
time, shall be deemed to have been made on the next succeeding Business Day. If
any payment falls due on a day that is not a Business Day, then such due date
shall be extended to the next succeeding Business Day (except that in the case
of LIBOR Loans to which the provisions of clause (iv) in SECTION 2.10 are
applicable, such due date shall be the next preceding Business Day), and such
extension of time shall then be included in the computation of payment of
interest, fees or other applicable amounts.

         (b) The Agent will distribute to the Lenders like amounts relating to
payments made to the Agent for the account of the Lenders as follows: (i) if the
payment is received by 12:00 noon, Charlotte time, in immediately available
funds, the Agent will make available to each relevant Lender on the same date,
by wire transfer of immediately available funds, such Lender's ratable share of
such payment (based on the percentage that the amount of the relevant payment
owing to such Lender bears to the total amount of such payment owing to all of
the relevant Lenders), and (ii) if such payment is received after 12:00 noon,
Charlotte time, or in other than immediately available funds, the Agent will
make available to each such Lender its ratable share of such payment by wire
transfer of immediately available funds on the next succeeding Business Day (or
in the case of uncollected funds, as soon as practicable after collected). If
the Agent shall not have made a required distribution to the appropriate Lenders
as required hereinabove after receiving a payment for the account of such
Lenders, the Agent will pay to each such Lender, on demand, its ratable share of





                                       28
<PAGE>   30

such payment with interest thereon at the Federal Funds Rate for each day from
the date such amount was required to be disbursed by the Agent until the date
repaid to such Lender.

         (c) Unless the Agent shall have received written notice from the
Borrower prior to the date on which any payment is due to any Lender hereunder
that such payment will not be made in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date, and the Agent
may, in reliance on such assumption, but shall not be obligated to, cause to be
distributed to such Lender on such due date an amount equal to the amount then
due to such Lender. If and to the extent the Borrower shall not have so made
such payment in full to the Agent, and without limiting the obligation of the
Borrower to make such payment in accordance with the terms hereof, such Lender
shall repay to the Agent forthwith on demand such amount so distributed to such
Lender, together with interest thereon for each day from the date such amount is
so distributed to such Lender until the date repaid to the Agent, at the Federal
Funds Rate.

         (d) Each Lender for whose account any payment is to be made hereunder
may, but shall not be obligated to, debit the amount of any such payment not
made as and when required hereunder to any ordinary deposit account of the
Borrower with such Lender (with prompt notice to the Agent and the Borrower);
provided, however, that the failure to give such notice shall not affect the
validity of such debit by such Lender.

         (e) All computations of interest and fees hereunder (including
computations of the Reserve Requirement) shall be made on the basis of a year
consisting of 360 days and the actual number of days (including the first day,
but excluding the last day) elapsed for LIBOR Loans and of 365/366 days and the
actual number of days (including the first day, but excluding the last day)
elapsed for Base Rate Loans.

         2.13     Recovery of Payments.

         (a) The Borrower agrees that to the extent the Borrower makes a payment
or payments to or for the account of the Agent or any Lender, which payment or
payments or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party under any bankruptcy, insolvency or similar state or
federal law, common law or equitable cause, then, to the extent of such payment
or repayment, the Obligation intended to be satisfied shall be revived and
continued in full force and effect as if such payment had not been received.

         (b) If any amounts distributed by the Agent to any Lender are
subsequently returned or repaid by the Agent to the Borrower or its
representative or successor in interest, whether by court order or by settlement
approved by the Lender in question, such Lender will, promptly upon receipt of
notice thereof from the Agent, pay the Agent such amount. If any such amounts
are recovered by the Agent from the Borrower or its representative or successor
in interest, the Agent will redistribute such amounts to the Lenders on the same
basis as such amounts were originally distributed.

         2.14 Use of Proceeds. The proceeds of the Loans shall be used solely
(i) to provide working capital for the Borrower's and the Subsidiaries' general
business purposes, including (x) financing of Permitted Acquisitions together





                                       29
<PAGE>   31

with legal and accounting fees and other transaction costs incurred in
connection therewith, (y) financing of patient receivables to the extent
permitted pursuant to Section 7.5(ix) and (z) repurchases of the Borrower's
Common Stock to the extent permitted pursuant to SECTION 7.6(A)(III) and (ii) to
pay certain fees and expenses in connection with this Facility.

         2.15     Pro Rata Treatment.

         (a) All fundings, continuations and conversions of Loans shall be made
by the Lenders pro rata on the basis of their respective Commitments to provide
Loans (in the case of the initial funding of Loans pursuant to SECTION 2.2) or
on the basis of their respective outstanding Loans (in the case of continuations
and conversions of Loans pursuant to SECTION 2.11, and additionally in all cases
in the event the Commitments have expired or have been terminated), as the case
may be from time to time. All payments on account of principal of or interest on
any Loans, fees or any other Obligations owing to or for the account of any one
or more Lenders shall be apportioned ratably among such Lenders in proportion to
the amounts of such principal, interest, fees or other Obligations owed to them
respectively.

         (b) Each Lender agrees that if it shall receive any amount hereunder
(whether by voluntary payment, realization upon security, exercise of the right
of setoff or banker's lien, counterclaim or cross action, or otherwise, other
than pursuant to SECTION 2.16, SECTION 2.18 or SECTION 10.7) applicable to the
payment of any of the Obligations that exceeds its ratable share (according to
the proportion of (i) the amount of such Obligations due and payable to such
Lender at such time to (ii) the aggregate amount of such Obligations due and
payable to all Lenders at such time) of payments on account of such Obligations
then or therewith obtained by all the Lenders to which such payments are
required to have been made, such Lender shall forthwith purchase from the other
Lenders such participations in such Obligations as shall be necessary to cause
such purchasing Lender to share the excess payment or other recovery ratably
with each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Lender, such purchase from
each such other Lender shall be rescinded and each such other Lender shall repay
to the purchasing Lender the purchase price to the extent of such recovery,
together with an amount equal to such other Lender's ratable share (according to
the proportion of (i) the amount of such other Lender's required repayment to
(ii) the total amount so recovered from the purchasing Lender) of any interest
or other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to the provisions of this subsection
may, to the fullest extent permitted by law, exercise any and all rights of
payment (including, without limitation, setoff, banker's lien or counterclaim)
with respect to such participation as fully as if such participant were a direct
creditor of the Borrower in the amount of such participation. If under any
applicable bankruptcy, insolvency or similar law, any Lender receives a secured
claim in lieu of a setoff to which this subsection applies, such Lender shall,
to the extent practicable, exercise its rights in respect of such secured claim
in a manner consistent with the rights of the Lenders entitled under this
subsection to share in the benefits of any recovery on such secured claim.

         2.16     Increased Costs; Change in Circumstances; Illegality; etc.

         (a) If, at any time after the date hereof and from time to time, the
introduction of or any change in any applicable law, rule or regulation or in
the interpretation or administration thereof by any Governmental Authority
charged with the interpretation or administration thereof, or compliance by any
Lender with any guideline or request from any such Governmental Authority
(whether or not having the force of law), shall (i) subject such Lender to any
tax or other charge, or change the basis of taxation of payments to such Lender,
in respect of any of its LIBOR Loans or any other amounts payable hereunder or
its obligation to make, fund or maintain any LIBOR Loans (other than any change
in the rate or basis of tax on the overall net income of such Lender or its
applicable Lending Office), (ii) impose, modify or deem applicable any reserve,
special deposit or similar requirement (other than as a result of any change in
the Reserve Requirement) against assets of, deposits with or for the account of,
or credit extended by, such Lender or its applicable Lending Office, or (iii)
impose on such Lender or its applicable Lending Office any other condition, and
the result of any of the foregoing shall be to increase the cost to such Lender
of making or maintaining any LIBOR Loans or to reduce the amount of any sum
received or receivable by such Lender hereunder, the Borrower will, promptly
upon demand therefor by such Lender, pay to such Lender such additional amounts
as shall compensate such Lender for such increase in costs or reduction in
return.

         (b) If, at any time after the date hereof and from time to time, any
Lender shall have reasonably determined that the introduction of or any change
in any applicable law, rule or regulation regarding capital adequacy or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof, or compliance by such Lender
with any guideline or request from any such Governmental Authority (whether or
not having the force of law), has or would have the effect, as a consequence of
such Lender's Commitment or Loans hereunder, of reducing the rate of return on
the capital of such Lender or any Person controlling such Lender to a level
below that which such Lender or controlling Person could have achieved but for
such introduction, change or compliance (taking into account such Lender's or
controlling Person's policies with respect to capital adequacy), the Borrower
will, promptly upon demand therefor by such Lender therefor, pay to such Lender
such additional amounts as will compensate such Lender or controlling Person for
such reduction in return.

         (c) If, on or prior to the first day of any Interest Period, (y) the
Agent shall have determined that adequate and reasonable means do not exist for
ascertaining the applicable LIBOR Rate for such Interest Period or (z) the Agent
shall have received written notice from the Required Lenders of their
determination that the rate of interest referred to in the definition of "LIBOR
Rate" upon the basis of which the Adjusted LIBOR Rate for LIBOR Loans for such
Interest Period is to be determined will not adequately and fairly reflect the
cost to such Lenders of making or maintaining LIBOR Loans during such Interest
Period, the Agent will forthwith so notify the Borrower and the Lenders. Upon
such notice, (i) all then outstanding LIBOR Loans shall automatically, on the
expiration date of the respective Interest Periods applicable thereto (unless
then repaid in full), be converted into Base Rate Loans, (ii) the obligation of
the Lenders to make, to convert Base Rate Loans into, or to continue, LIBOR
Loans shall be suspended (including pursuant to the Borrowing to which such
Interest Period applies), and (iii) any Notice of Borrowing or Notice of
Conversion/Continuation given at any time thereafter with respect to LIBOR Loans





                                       31
<PAGE>   33

shall be deemed to be a request for Base Rate Loans, in each case until the
Agent or the Required Lenders, as the case may be, shall have determined that
the circumstances giving rise to such suspension no longer exist (and the
Required Lenders, if making such determination, shall have so notified the
Agent), and the Agent shall have so notified the Borrower and the Lenders.

         (d) Notwithstanding any other provision in this Agreement, if, at any
time after the date hereof and from time to time, any Lender shall have
determined in good faith that the introduction of or any change in any
applicable law, rule or regulation or in the interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof, or compliance with any guideline or request from any
such Governmental Authority (whether or not having the force of law), has or
would have the effect of making it unlawful for such Lender to make or to
continue to make or maintain LIBOR Loans, such Lender will forthwith so notify
the Agent and the Borrower. Upon such notice, (i) each of such Lender's then
outstanding LIBOR Loans shall automatically, on the expiration date of the
respective Interest Period applicable thereto (or, to the extent any such LIBOR
Loan may not lawfully be maintained as a LIBOR Loan until such expiration date,
upon such notice), be converted into a Base Rate Loan, (ii) the obligation of
such Lender to make, to convert Base Rate Loans into, or to continue, LIBOR
Loans shall be suspended (including pursuant to any Borrowing for which the
Agent has received a Notice of Borrowing but for which the Borrowing Date has
not arrived), and (iii) any Notice of Borrowing or Notice of
Conversion/Continuation given at any time thereafter with respect to LIBOR Loans
shall, as to such Lender, be deemed to be a request for a Base Rate Loan, in
each case until such Lender shall have determined that the circumstances giving
rise to such suspension no longer exist and shall have so notified the Agent,
and the Agent shall have so notified the Borrower.

         (e) Determinations by the Agent or any Lender for purposes of this
Section of any increased costs, reduction in return, market contingencies,
illegality or any other matter shall, absent manifest error, be conclusive,
provided that such determinations are made in good faith. No failure by the
Agent or any Lender at any time to demand payment of any amounts payable under
this Section shall constitute a waiver of its right to demand payment of any
additional amounts arising at any subsequent time. Nothing in this Section shall
require or be construed to require the Borrower to pay any interest, fees, costs
or other amounts in excess of that permitted by applicable law.

         2.17     Taxes.

         (a) Any and all payments by the Borrower hereunder or under any Note
shall be made, in accordance with the terms hereof and thereof, free and clear
of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, other than net income and franchise taxes imposed on the Agent or any
Lender by the United States or by the jurisdiction under the laws of which the
Agent or such Lender, as the case may be, is organized or in which its principal
office or (in the case of a Lender) its applicable Lending Office is located, or
any political subdivision or taxing authority thereof (all such nonexcluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder or under any





                                       32
<PAGE>   34

Note to the Agent or any Lender, (i) the sum payable shall be increased as may
be necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section), the Agent or such
Lender, as the case may be, receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower will make such
deductions, (iii) the Borrower will pay the full amount deducted to the relevant
taxation authority or other authority in accordance with applicable law and (iv)
the Borrower will deliver to the Agent or such Lender, as the case may be,
evidence of such payment.

         (b) The Borrower will indemnify the Agent and each Lender for the full
amount of Taxes (including, without limitation, any Taxes imposed by any
jurisdiction on amounts payable under this Section) paid by the Agent or such
Lender, as the case may be, and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
were correctly or legally asserted. This indemnification shall be made within 30
days from the date the Agent or such Lender, as the case may be, makes written
demand therefor.

         (c) Each of the Agent and the Lenders agrees that if it subsequently
recovers, or receives a permanent net tax benefit with respect to, any amount of
Taxes (i) previously paid by it and as to which it has been indemnified by or on
behalf of the Borrower or (ii) previously deducted by the Borrower (including,
without limitation, any Taxes deducted from any additional sums payable under
clause (i) of subsection (a) above), the Agent or such Lender, as the case may
be, shall reimburse the Borrower to the extent of the amount of any such
recovery or permanent net tax benefit (but only to the extent of indemnity
payments made, or additional amounts paid, by or on behalf of the Borrower under
this Section with respect to the Taxes giving rise to such recovery or tax
benefit); provided, however, that the Borrower, upon the request of the Agent or
such Lender, agrees to repay to the Agent or such Lender, as the case may be,
the amount paid over to the Borrower (together with any penalties, interest or
other charges), in the event the Agent or such Lender is required to repay such
amount to the relevant taxing authority or other Governmental Authority. The
determination by the Agent or any Lender of the amount of any such recovery or
permanent net tax benefit shall, in the absence of manifest error, be conclusive
and binding.

         (d) If any Lender is incorporated or organized under the laws of a
jurisdiction other than the United States of America or any state thereof (a
"Non-U.S. Lender") and claims exemption from United States withholding tax
pursuant to the Internal Revenue Code, such Non-U.S. Lender will deliver to each
of the Agent and the Borrower, on or prior to the Closing Date (or, in the case
of a Non-U.S. Lender that becomes a party to this Agreement as a result of an
assignment after the Closing Date, on the effective date of such assignment),
(i) in the case of a Non-U.S. Lender that is a "bank" for purposes of Section
881(c)(3)(A) of the Internal Revenue Code, a properly completed Internal Revenue
Service Form 4224 or 1001, as applicable (or successor forms), certifying that
such Non-U.S. Lender is entitled to an exemption from or a reduction of
withholding or deduction for or on account of United States federal income taxes
in connection with payments under this Agreement or any of the Notes, together
with a properly completed Internal Revenue Service Form W-8 or W-9, as
applicable (or successor forms), and (ii) in the case of a Non-U.S. Lender that
is not a "bank" for purposes of Section 881(c)(3)(A) of the Internal Revenue
Code, a certificate in form and substance reasonably satisfactory to the Agent





                                       33
<PAGE>   35

and the Borrower and to the effect that (x) such Non-U.S. Lender is not a "bank"
for purposes of Section 881(c)(3)(A) of the Internal Revenue Code, is not
subject to regulatory or other legal requirements as a bank in any jurisdiction,
and has not been treated as a bank for purposes of any tax, securities law or
other filing or submission made to any governmental authority, any application
made to a rating agency or qualification for any exemption from any tax,
securities law or other legal requirements, (y) is not a 10-percent shareholder
for purposes of Section 881(c)(3)(B) of the Internal Revenue Code and (z) is not
a controlled foreign corporation receiving interest from a related person for
purposes of Section 881(c)(3)(C) of the Internal Revenue Code, together with a
properly completed Internal Revenue Service Form W-8 or W-9, as applicable (or
successor forms). Each such Non-U.S. Lender further agrees to deliver to each of
the Agent and the Borrower an additional copy of each such relevant form on or
before the date that such form expires or becomes obsolete or after the
occurrence of any event (including a change in its applicable Lending Office)
requiring a change in the most recent forms so delivered by it, in each case
certifying that such Non-U.S. Lender is entitled to an exemption from or a
reduction of withholding or deduction for or on account of United States federal
income taxes in connection with payments under this Agreement or any of the
Notes, unless an event (including, without limitation, any change in treaty, law
or regulation) has occurred prior to the date on which any such delivery would
otherwise be required, which event renders all such forms inapplicable or the
exemption to which such forms relate unavailable and such Non-U.S. Lender
notifies the Agent and the Borrower that it is not entitled to receive payments
without deduction or withholding of United States federal income taxes. Each
such Non-U.S. Lender will promptly notify the Agent and the Borrower of any
changes in circumstances that would modify or render invalid any claimed
exemption or reduction.

         (e) If any Lender is entitled to a reduction in (and not a complete
exemption from) the applicable withholding tax, the Borrower and the Agent may
withhold from any interest payment to such Lender an amount equivalent to the
applicable withholding tax after taking into account such reduction. If any of
the forms or other documentation required under subsection (d) above are not
delivered to the Agent as therein required, then the Borrower and the Agent may
withhold from any interest payment to such Lender not providing such forms or
other documentation an amount equivalent to the applicable withholding tax.

         2.18 Compensation. The Borrower will compensate each Lender upon demand
for all losses, expenses and liabilities (including, without limitation, any
loss, expense or liability incurred by reason of the liquidation or reemployment
of deposits or other funds required by such Lender to fund or maintain LIBOR
Loans) that such Lender may incur or sustain (i) if for any reason (other than a
default by such Lender) a Borrowing or continuation of, or conversion into, a
LIBOR Loan does not occur on a date specified therefor in a Notice of Borrowing
or Notice of Conversion/Continuation, (ii) if any repayment, prepayment or
conversion of any LIBOR Loan occurs on a date other than the last day of an
Interest Period applicable thereto (including as a consequence of acceleration
of the maturity of the Loans pursuant to SECTION 8.2), (iii) if any prepayment
of any LIBOR Loan is not made on any date specified in a notice of prepayment
given by the Borrower or (iv) as a consequence of any other failure by the
Borrower to make any payments with respect to any LIBOR Loan when due hereunder.
Calculation of all amounts payable to a Lender under this Section shall be made
as though such Lender had actually funded its relevant LIBOR Loan through the
purchase of a Eurodollar deposit bearing interest at the LIBOR Rate in an amount
equal to the amount of such LIBOR Loan and having a maturity comparable to the
relevant Interest Period; provided, however, that each Lender may fund its LIBOR





                                       34
<PAGE>   36

Loans in any manner it sees fit, and the foregoing assumption shall be utilized
only for the calculation of amounts payable under this Section. Determinations
by any Lender for purposes of this Section of any such losses, expenses or
liabilities shall, absent manifest error, be conclusive, provided that such
determinations are made in good faith.


                                  ARTICLE III.

                             CONDITIONS OF BORROWING

         (g) The Agent shall have received evidence in form and substance

         (b) Each of the representations and warranties contained in ARTICLE IV

the statements contained in subsections (b) and (c) above are true, both as of
the date of such notice or request and as of the relevant Borrowing Date.


                                   ARTICLE IV.

                         REPRESENTATIONS AND WARRANTIES

         To induce the Agent and the Lenders to enter into this Agreement and to
induce the Lenders to extend the credit contemplated hereby, the Borrower
represents and warrants to the Agent and the Lenders as follows:

         4.1 Corporate Organization and Power. Each of the Borrower and its
Subsidiaries (i) is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and (ii) is
duly qualified to do business as a foreign corporation and is in good standing
in each jurisdiction where the nature of its business or the ownership of its
properties requires it to be so qualified, except where the failure to be so
qualified would not, individually or in the aggregate, be reasonably likely to
have a Material Adverse Effect; and each of the Borrower and the Subsidiary
Guarantors has the full corporate power and authority to execute, deliver and
perform the Credit Documents to which it is or will be a party, to own and hold
its property and to engage in its business as presently conducted.




                                       38
<PAGE>   40

         4.2 Authorization; Enforceability. Each of the Borrower and its
Subsidiaries has taken, or on the Closing Date will have taken, all necessary
corporate action to execute, deliver and perform each of the Credit Documents to
which it is or will be a party, and has, or on the Closing Date (or any later
date of execution and delivery) will have, validly executed and delivered each
of the Credit Documents to which it is or will be a party. This Agreement and
each of the other Credit Documents constitutes, or upon execution and delivery
will constitute, the legal, valid and binding obligation of each of the Borrower
and its Subsidiaries that is a party hereto or thereto, enforceable against it
in accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting creditors' rights generally, by general equitable principles or by
principles of good faith and fair dealing.

         4.3 No Violation. The execution, delivery and performance by each of
the Borrower and its Subsidiaries of this Agreement and each of the other Credit
Documents to which it is or will be a party, and compliance by it with the terms
hereof and thereof, do not and will not (i) violate any provision of its
articles or certificate of incorporation or bylaws or contravene any other
Requirement of Law applicable to it, (ii) conflict with, result in a breach of
or constitute (with notice, lapse of time or both) a default under any
indenture, agreement or other instrument to which it is a party, by which it or
any of its properties is bound or to which it is subject, (iii) result in a
Limitation on any Licenses applicable to the operations of the Borrower or any
of its Subsidiaries or adversely affect the ability of the Borrower or any of
its Subsidiaries to participate in any Third Party Payor Arrangement or (iv)
except for the Liens granted in favor of the Agent pursuant to the Security
Documents, result in or require the creation or imposition of any Lien upon any
of its properties or assets. No Subsidiary is a party to any agreement or
instrument or otherwise subject to any restriction or encumbrance that restricts
or limits its ability to make dividend payments or other distributions in
respect of its Capital Stock, to repay Indebtedness owed to the Borrower or any
other Subsidiary, to make loans or advances to the Borrower or any other
Subsidiary, or to transfer any of its assets or properties to the Borrower or
any other Subsidiary, in each case other than such restrictions or encumbrances
existing under or by reason of the Credit Documents or applicable Requirements
of Law.

         4.4      Governmental and Third-Party Authorization; Permits.

         (a) No consent, approval, authorization or other action by, notice to,
or registration or filing with, any Governmental Authority or other Person is or
will be required as a condition to or otherwise in connection with the due
execution, delivery and performance by each of the Borrower and its Subsidiaries
of this Agreement or any of the other Credit Documents to which it is or will be
a party or the legality, validity or enforceability hereof or thereof, other
than (i) filings of Uniform Commercial Code financing statements and other
instruments and actions necessary to perfect the Liens created by the Security
Documents, (ii) consents, authorizations and filings that have been (or on or






                                       39
<PAGE>   41

prior to the Closing Date will have been) made or obtained and that are (or on
the Closing Date will be) in full force and effect, which consents,
authorizations and filings are listed on SCHEDULE 4.4, and (iii) consents and
filings the failure to obtain or make which would not, individually or in the
aggregate, have a Material Adverse Effect.

         (b) Each of the Borrower and its Subsidiaries has, and is in good
standing with respect to, all governmental approvals, Licenses, Reimbursement
Approvals and other authorizations necessary to conduct its business as
presently conducted and to own or lease and operate its properties, except for
those the failure to obtain which would not be reasonably likely, individually
or in the aggregate, to have a Material Adverse Effect. Without limitation of
the foregoing, the Borrower and each Subsidiary has, to the extent applicable,
(i) obtained and maintains in good standing all required Licenses and
Reimbursement Approvals, except where the failure to do so would not have a
Material Adverse Effect, and (ii) to the extent prudent and customary in the
industry in which the Borrower and such Subsidiary is engaged, obtained and
maintains accreditation from all generally recognized accrediting agencies for
the Borrower and its Subsidiaries. No Medicaid or Medicare certifications are
required for the operation of the business of the Borrower or any Subsidiary and
neither the Borrower nor any Subsidiary is required to have entered into
Medicaid or Medicare provider agreements for the operation of its business.

         4.5 Litigation. There are no actions, investigations, suits or
proceedings pending or, to the knowledge of the Borrower, threatened, at law, in
equity or in arbitration, before any court, other Governmental Authority or
other Person, (i) against or affecting the Borrower, any of its Subsidiaries or
any of their respective properties that would, if adversely determined, be
reasonably likely to have a Material Adverse Effect, or (ii) with respect to
this Agreement or any of the other Credit Documents.

         4.6 Taxes. Each of the Borrower and its Subsidiaries has timely filed
all federal, state and local tax returns and reports required to be filed by it
and has paid all taxes, assessments, fees and other charges levied upon it or
upon its properties that are shown thereon as due and payable, other than those
that are being contested in good faith and by proper proceedings and for which
adequate reserves have been established in accordance with GAAP. Such returns
accurately reflect in all material respects all liability for taxes of the
Borrower and its Subsidiaries for the periods covered thereby. There is no
ongoing audit or examination or, to the knowledge of the Borrower, other
investigation by any Governmental Authority of the tax liability of the Borrower
or any of its Subsidiaries, and there is no unresolved claim by any Governmental
Authority concerning the tax liability of the Borrower or any of its
Subsidiaries for any period for which tax returns have been or were required to
have been filed, other than claims for which adequate reserves have been
established in accordance with GAAP. Neither the Borrower nor any of its
Subsidiaries has waived or extended or has been requested to waive or extend the
statute of limitations relating to the payment of any taxes.

         4.7 Subsidiaries. SCHEDULE 4.7 sets forth a list, as of the Closing
Date, of all of the Subsidiaries of the Borrower and, as to each such
Subsidiary, the percentage ownership (direct and indirect) of the Borrower in
each class of its capital stock and each direct owner thereof. Except for the
shares of capital stock expressly indicated on SCHEDULE 4.7, there are no shares
of capital stock, warrants, rights, options or other equity securities, or other
Capital Stock of any Subsidiary of the Borrower outstanding or reserved for any
purpose. All outstanding shares of capital stock of each Subsidiary of the
Borrower are duly and validly issued, fully paid and nonassessable. The Borrower






                                       40
<PAGE>   42

is the sole legal, record and beneficial owner of, and has good and valid title
to, all such capital stock, free and clear of all Liens other than the Liens
created pursuant to the Pledge and Security Agreement.

         4.8 Full Disclosure. All factual information heretofore or
contemporaneously furnished to the Agent or any Lender in writing by or on
behalf of the Borrower or any of its Subsidiaries for purposes of or in
connection with this Agreement and the transactions contemplated hereby is, and
all other such factual information hereafter furnished to the Agent or any
Lender in writing by or on behalf of the Borrower or any of its Subsidiaries
will be, true and accurate in all material respects on the date as of which such
information is dated or certified (or, if such information has been amended or
supplemented, on the date as of which any such amendment or supplement is dated
or certified) and not made incomplete by omitting to state a material fact
necessary to make the statements contained therein, in light of the
circumstances under which such information was provided, not misleading.

         4.9 Margin Regulations. Neither the Borrower nor any of its
Subsidiaries is engaged principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying
Margin Stock. No proceeds of the Loans will be used, directly or indirectly, to
purchase or carry any Margin Stock, to extend credit for such purpose or for any
other purpose that would violate or be inconsistent with Regulations T, U or X
or any provision of the Exchange Act.

         4.10 No Material Adverse Change. There has been no Material Adverse
Change since December 31, 1997, and there exists no event, condition or state of
facts that could reasonably be expected to result in a Material Adverse Change.

         4.11     Financial Matters.

         (a) The Borrower has heretofore furnished to the Agent copies of (i)
the audited financial statements as of December 31, 1997, and (ii) the unaudited
consolidated balance sheet of the Borrower and its Subsidiaries as of December
31, 1998, and the related statements of income and cash flows for the
twelve-month period then ended. Such financial statements have been prepared in
accordance with GAAP (subject, with respect to the unaudited financial
statements, to the absence of notes required by GAAP and to normal year-end
adjustments) and present fairly the financial condition of the Borrower and its
Subsidiaries on a consolidated basis as of the respective dates thereof and the
consolidated results of operations of the Borrower and its Subsidiaries for the
respective periods then ended. Except as fully reflected in the most recent
financial statements referred to above and the notes thereto, there are no
material liabilities or obligations with respect to the Borrower or any of its
Subsidiaries of any nature whatsoever (whether absolute, contingent or otherwise
and whether or not due).

         (b) The Borrower has prepared, and has heretofore furnished to the
Agent a copy of, annual projected balance sheets and statements of income and
cash flows of the Borrower for the years ended December 31, 1999 through
December 31, 2002, giving effect to the extensions of credit made under this
Agreement, and the payment of transaction fees and expenses related to the
foregoing (the "Projections"). In the opinion of management of the Borrower, the
assumptions used in the preparation of the Projections were fair, complete and
reasonable when made and continue to be fair, complete and reasonable as of the
date hereof. The Projections have been prepared in good faith by the executive





                                       41
<PAGE>   43


and financial personnel of the Borrower, are complete and represent a reasonable
estimate of the future performance and financial condition of the Borrower,
subject to the uncertainties and approximations inherent in any projections.

         (c) Each of the Borrower and its Subsidiaries, after giving effect to
the consummation of the transactions contemplated hereby, (i) has capital
sufficient to carry on its businesses as conducted and as proposed to be
conducted, (ii) has assets with a fair saleable value, determined on a going
concern basis, (y) not less than the amount required to pay the probable
liability on its existing debts as they become absolute and matured and (z)
greater than the total amount of its liabilities (including identified
Contingent Obligations, valued at the amount that can reasonably be expected to
become absolute and matured), and (iii) does not intend to, and does not believe
that it will, incur debts or liabilities beyond its ability to pay such debts
and liabilities as they mature.

         4.12 Ownership of Properties. Each of the Borrower and its Subsidiaries
(i) has good and marketable title to all real property owned by it, (ii) holds
interests as lessee under valid leases in full force and effect with respect to
all material leased real and personal property used in connection with its
business, except to the extent that the Borrower and Subsidiaries are not
correctly reflected as lessees under leases acquired by or assigned to the
Borrower or a Subsidiary, so long as the Borrower is making reasonable efforts
to correct such leases and such condition is not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect, (iii) possesses or
has rights to use licenses, patents, copyrights, trademarks, service marks,
trade names and other assets sufficient to enable it to continue to conduct its
business substantially as heretofore conducted and without any material conflict
with the rights of others, and (iv) has good title to all of its other
properties and assets reflected in the most recent financial statements referred
to in SECTION 4.11(A) (except as sold or otherwise disposed of since the date
thereof in the ordinary course of business), in each case under (i), (ii), (iii)
and (iv) above free and clear of all Liens other than Permitted Liens. SCHEDULE
4.12 lists, as of the Closing Date, all real property interests of the Borrower
and its Subsidiaries, indicating in each case the address of the property, the
nature of use of the premises, and whether such interest is a leasehold or fee
ownership interest.

         4.13 ERISA. Each Plan is and has been administered in compliance in all
material respects with all applicable Requirements of Law, including, without
limitation, the applicable provisions of ERISA and the Internal Revenue Code. No
ERISA Event has occurred and is continuing or, to the knowledge of the Borrower,
is reasonably expected to occur with respect to any Plan, in either case that
would be reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect. No Plan has any Unfunded Pension Liability, and neither the
Borrower nor any ERISA Affiliate has engaged in a transaction that could be
subject to Section 4069 or 4212(c) of ERISA, in either instance where the same
would be reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect. Neither the Borrower nor any ERISA Affiliate is required to
contribute to or has, or has at any time had, any liability to a Multiemployer
Plan. To the best of the Borrower's actual knowledge, no condition or event
exists, with respect to any Plan (other than a Multiemployer Plan) which is
sponsored by other than the Borrower or any ERISA Affiliate, and with respect to





                                       42
<PAGE>   44


which the Borrower or any ERISA Affiliate and the sponsor thereof are considered
members of an affiliated service group, which would have a Material Adverse
Effect.

         4.14     Environmental Matters.

         (a) No Hazardous Substances are or have been generated, used, located,
released, treated, disposed of or stored by the Borrower or any of its
Subsidiaries or, to the knowledge of the Borrower, by any other Person
(including any predecessor in interest) or otherwise, in, on or under any
portion of any real property, leased or owned, of the Borrower or any of its
Subsidiaries, except in material compliance with all applicable Environmental
Laws, and no portion of any such real property or, to the knowledge of the
Borrower, any other real property at any time leased, owned or operated by the
Borrower or any of its Subsidiaries, has been contaminated by any Hazardous
Substance, in either case except to the extent the existence of any Hazardous
Substance(s) is not reasonably likely, individually or in the aggregate, to have
a Material Adverse Effect; and no portion of any real property, leased or owned,
of the Borrower or any of its Subsidiaries has been or is presently the subject
of an environmental audit, assessment or remedial action.

         (b) No portion of any real property, leased or owned, of the Borrower
or any of its Subsidiaries has been used by the Borrower or any of its
Subsidiaries or, to the knowledge of the Borrower, by any other Person, as or
for a mine, a landfill, a dump or other disposal facility, a gasoline service
station, or (other than for petroleum substances stored in the ordinary course
of business) a petroleum products storage facility; no portion of such real
property or any other real property at any time leased, owned or operated by the
Borrower or any of its Subsidiaries has, pursuant to any Environmental Law, been
placed on the "National Priorities List" or "CERCLIS List" (or any similar
federal, state or local list) of sites subject to possible environmental
problems; and there are not and have never been any underground storage tanks
situated on any real property, leased or owned, of the Borrower or any of its
Subsidiaries, except to the extent any such tanks are not reasonably likely,
individually or in the aggregate, to have a Material Adverse Effect.

         (c) All activities and operations of the Borrower and its Subsidiaries
are in compliance with the requirements of all applicable Environmental Laws,
except to the extent the failure so to comply, individually or in the aggregate,
would not be reasonably likely to have a Material Adverse Effect. Each of the
Borrower and its Subsidiaries has obtained all licenses and permits under
Environmental Laws necessary to its respective operations; all such licenses and
permits are being maintained in good standing; and each of the Borrower and its
Subsidiaries is in compliance with all terms and conditions of such licenses and
permits, except for such licenses and permits the failure to obtain, maintain or
comply with which would not be reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect. Neither the Borrower nor any of
its Subsidiaries is involved in any suit, action or proceeding, or has received
any notice, complaint or other request for information from any Governmental
Authority or other Person, with respect to any actual or alleged Environmental
Claims that, if adversely determined, would be reasonably likely, individually
or in the aggregate, to have a Material Adverse Effect; and, to the knowledge of
the Borrower, there are no threatened actions, suits, proceedings or
investigations with respect to any such Environmental Claims, nor any basis
therefor.




                                       43
<PAGE>   45

         4.15 Compliance With Laws. Each of the Borrower and its Subsidiaries
has timely filed all material reports, documents and other materials required to
be filed by it under all applicable Requirements of Law with any Governmental
Authority, has retained all material records and documents required to be
retained by it under all applicable Requirements of Law, and is otherwise in
compliance with all applicable Requirements of Law in respect of the conduct of
its business and the ownership and operation of its properties, except for such
Requirements of Law the failure to comply with which, individually or in the
aggregate, would not be reasonably likely to have a Material Adverse Effect.

         4.16 Regulated Industries. Neither the Borrower nor any of its
Subsidiaries is (i) an "investment company," a company "controlled" by an
"investment company," or an "investment advisor," within the meaning of the
Investment Company Act of 1940, as amended, or (ii) a "holding company," a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," within the meaning
of the Public Utility Holding Company Act of 1935, as amended.

         4.17 Insurance. SCHEDULE 4.17 sets forth a true and complete summary of
all insurance policies or arrangements carried or maintained by the Borrower and
its Subsidiaries as of the Closing Date, indicating in each case the insurer,
policy number, expiration, amount and type of coverage and deductibles. The
assets, properties and business of the Borrower and its Subsidiaries are insured
against such hazards and liabilities, under such coverages and in such amounts,
as are customarily maintained by prudent companies similarly situated and under
policies issued by insurers of recognized responsibility.

         4.18 Material Contracts. SCHEDULE 4.18 lists, as of the Closing Date,
each "material contract" (within the meaning of Item 601(b)(10) of Regulation
S-K under the Exchange Act) to which the Borrower or any of its Subsidiaries is
a party, by which any of them or their respective properties is bound or to
which any of them is subject (collectively, "Material Contracts"), and also
indicates the parties, subject matter and term thereof. As of the Closing Date,
(i) each Material Contract is in full force and effect and is enforceable by the
Borrower or the Subsidiary that is a party thereto in accordance with its terms,
and (ii) neither the Borrower nor any of its Subsidiaries (nor, to the knowledge
of the Borrower, any other party thereto) is in breach of or default under any
Material Contract in any material respect or has given notice of termination or
cancellation of any Material Contract.

         4.19 Security Documents. The provisions of each of the Security
Documents (whether executed and delivered prior to or on the Closing Date or
thereafter) are and will be effective to create in favor of the Agent, for its
benefit and the benefit of the Lenders, a valid and enforceable security
interest in and Lien upon all right, title and interest of each of the Borrower
and its Subsidiaries that is a party thereto in and to the Collateral purported
to be pledged by it thereunder and described therein, and upon (i) the initial
extension of credit hereunder, (ii) the filing of appropriately completed
Uniform Commercial Code financing statements and continuations thereof in the
jurisdictions specified therein, (iii) the filing of appropriately completed
short-form assignments in the U.S. Patent and Trademark Office and the U.S.
Copyright Office, (iv) in the case of uncertificated securities, compliance with
Section 8-313 (or its successor provision) of the applicable Uniform Commercial
Code, and (v) the possession by the Agent of any certificates evidencing the
securities pledged thereby, such security interest and Lien shall constitute a






                                       44
<PAGE>   46

fully perfected and first priority security interest in and Lien upon such
right, title and interest of the Borrower or such Subsidiary, as applicable, in
and to such Collateral, to the extent that such security interest and Lien can
be perfected by such filings, actions and possession, subject only to Permitted
Liens.

         4.20 Labor Relations. Neither the Borrower nor any of its Subsidiaries
is engaged in any unfair labor practice within the meaning of the National Labor
Relations Act of 1947, as amended. There is (i) no unfair labor practice
complaint before the National Labor Relations Board, or grievance or arbitration
proceeding arising out of or under any collective bargaining agreement, pending
or, to the knowledge of the Borrower, threatened, against the Borrower or any of
its Subsidiaries, (ii) no strike, lock-out, slowdown, stoppage, walkout or other
labor dispute pending or, to the knowledge of the Borrower, threatened, against
the Borrower or any of its Subsidiaries, and (iii) to the knowledge of the
Borrower, no petition for certification or union election or union organizing
activities taking place with respect to the Borrower or any of its Subsidiaries.

         4.21 Year 2000 Compatibility. Any reprogramming required to permit the
proper functioning, before, on and after January 1, 2000, of (i) the Borrower's
and its Subsidiaries' computer-based systems and (ii) equipment containing
embedded microchips (including systems and equipment supplied by others or with
which the Borrower's or any of its Subsidiaries' systems interface), and the
testing of all such systems and equipment, as so reprogrammed, will be completed
by June 30, 1999. The cost to the Borrower and its Subsidiaries of such
reprogramming and testing and of the reasonably foreseeable consequences of the
year 2000 to the Borrower and its Subsidiaries (including, without limitation,
reprogramming errors and the failure of others' systems or equipment) will not
result in a Default or Material Adverse Effect. Except for such of the
reprogramming referred to in the preceding sentence as may be necessary, the
computer and management information 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 to permit the Borrower and its
Subsidiaries to conduct their respective businesses without a Material Adverse
Effect.


                                   ARTICLE V.

                              AFFIRMATIVE COVENANTS

         The Borrower covenants and agrees that, until the termination of the
Commitments and the payment in full of all principal and interest with respect
to the Loans together with all other amounts then due and owing hereunder:

         5.1 Financial Statements. The Borrower will deliver to each Lender:

         (a) As soon as available and in any event within fifty (50) days after

<PAGE>   47

figures, if applicable, as of the end of and for the corresponding period in the
preceding fiscal year together with comparative budgeted figures for the fiscal

         individual's knowledge, (x) the consummation of such Permitted

         Borrowings made in connection therewith, the Borrower will be in
         compliance with the financial covenants contained in SECTIONS 6.1
         through 6.4, such compliance determined with regard to calculations
         made on a pro forma basis in accordance with GAAP as if each Target had

         such covenants (such calculations to be attached to the certificate),

this Section and in the description furnished under clause (i) of subsection (b)
above have been satisfied, that the same is permitted in accordance with the
terms of this Agreement, and that the matters certified to by the Financial

correct in all material respects as of the date such certificate is given, which
representation and warranty shall be deemed to be a representation and warranty
as of the date thereof for all purposes hereunder, including, without
limitation, for purposes of SECTIONS 3.2 and 8.1.

purchases or otherwise, have become, after the date hereof, the "beneficial
owner" (within the meaning of such term under Rule 13d-3 under the Exchange Act)
of securities of the Borrower representing 20% or more of the combined voting
power of the then outstanding securities of the Borrower ordinarily (and apart
from rights accruing under special circumstances) having the right to vote in
the election of directors; or (ii) the Board of Directors of the Borrower shall
cease to consist of a majority of the individuals who constituted the Board of
Directors as of the date hereof or who shall have become a member thereof
subsequent to the date hereof after having been nominated, or otherwise approved
in writing, by at least a majority of individuals who constituted the Board of
Directors of the Borrower as of the date hereof (or their replacements approved
as herein required).

         8.2 Remedies: Termination of Commitments, Acceleration, etc. Upon and
at any time after the occurrence and during the continuance of any Event of
Default, the Agent shall at the direction, or may with the consent, of the
Required Lenders, take any or all of the following actions at the same or
different times:

         (a) Declare the Commitments to be terminated, whereupon the same shall
terminate (provided that, upon the occurrence of an Event of Default pursuant to
SECTION 8.1(F) or SECTION 8.1(G), the Commitments shall automatically be
terminated);

         (b) Declare all or any part of the outstanding principal amount of the
Loans to be immediately due and payable, whereupon the principal amount so
declared to be immediately due and payable, together with all interest accrued
thereon and all other amounts payable under this Agreement, the Notes and the
other Credit Documents, shall become immediately due and payable without
presentment, demand, protest, notice of intent to accelerate or other notice or
legal process of any kind, all of which are hereby knowingly and expressly
waived by the Borrower (provided that, upon the occurrence of an Event of
Default pursuant to SECTION 8.1(F) or SECTION 8.1(G), all of the outstanding
principal amount of the Loans and all other amounts described in this subsection
(b) shall automatically become immediately due and payable without presentment,
demand, protest, notice of intent to accelerate or other notice or legal process
of any kind, all of which are hereby knowingly and expressly waived by the
Borrower); and

         (c) Exercise all rights and remedies available to it under this
Agreement, the other Credit Documents and applicable law.

         8.3 Remedies: Set-Off. In addition to all other rights and remedies
available under the Credit Documents or applicable law or otherwise, upon and at
any time after the occurrence and during the continuance of any Event of
Default, each Lender may, and each is hereby authorized by the Borrower, at any
such time and from time to time, to the fullest extent permitted by applicable
law, without presentment, demand, protest or other notice of any kind, all of
which are hereby knowingly and expressly waived by the Borrower, to set off and
to apply any and all deposits (general or special, time or demand, provisional
or final) and any other property at any time held (including at any branches or
agencies, wherever located), and any other indebtedness at any time owing, by
such Lender to or for the credit or the account of the Borrower against any or
all of the Obligations to such Lender now or hereafter existing, whether or not
such Obligations may be contingent or unmatured, the Borrower hereby granting to
each Lender a continuing security interest in and Lien upon all such deposits






                                       62
<PAGE>   64

and other property as security for such Obligations. Each Lender agrees promptly
to notify the Borrower and the Agent after any such set-off and application;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application.


                                   ARTICLE IX.

                                    THE AGENT

         9.1 Appointment. Each Lender hereby irrevocably appoints and authorizes
First Union to act as Agent hereunder and under the other Credit Documents and
to take such actions as agent on its behalf hereunder and under the other Credit
Documents, and to exercise such powers and to perform such duties, as are
specifically delegated to the Agent by the terms hereof or thereof, together
with such other powers and duties as are reasonably incidental thereto.

         9.2 Nature of Duties. The Agent shall have no duties or
responsibilities other than those expressly set forth in this Agreement and the
other Credit Documents. The Agent shall not have, by reason of this Agreement or
any other Credit Document, a fiduciary relationship in respect of any Lender;
and nothing in this Agreement or any other Credit Document, express or implied,
is intended to or shall be so construed as to impose upon the Agent any
obligations or liabilities in respect of this Agreement or any other Credit
Document except as expressly set forth herein or therein. The Agent may execute
any of its duties under this Agreement or any other Credit Document by or
through agents or attorneys-in-fact and shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact that it selects with
reasonable care. The Agent shall be entitled to consult with legal counsel,
independent public accountants and other experts selected by it with respect to
all matters pertaining to this Agreement and the other Credit Documents and its
duties hereunder and thereunder and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts. The Lenders hereby acknowledge that the Agent
shall not be under any duty to take any discretionary action permitted to be
taken by it pursuant to the provisions of this Agreement or any other Credit
Document unless it shall be requested in writing to do so by the Required
Lenders (or, where a higher percentage of the Lenders is expressly required
hereunder, such Lenders).

         9.3 Exculpatory Provisions. Neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates shall be (i)
liable for any action taken or omitted to be taken by it or such Person under or
in connection with the Credit Documents, except for its or such Person's own
gross negligence or willful misconduct, (ii) responsible in any manner to any
Lender for any recitals, statements, information, representations or warranties
herein or in any other Credit Document or in any document, instrument,
certificate, report or other writing delivered in connection herewith or
therewith, for the execution, effectiveness, genuineness, validity,
enforceability or sufficiency of this Agreement or any other Credit Document, or
for the financial condition of the Borrower, its Subsidiaries or any other
Person, or (iii) required to ascertain or make any inquiry concerning the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any other Credit Document or the existence or possible existence of
any Default or Event of Default, or to inspect the properties, books or records
of the Borrower or any of its Subsidiaries.




                                       63
<PAGE>   65

         9.4 Reliance by Agent. The Agent shall be entitled to rely, and shall
be fully protected in relying, upon any notice, statement, consent or other
communication (including, without limitation, any thereof by telephone,
telecopy, telex, telegram or cable) believed by it in good faith to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons. The Agent may deem and treat each Lender as the owner of its interest
hereunder for all purposes hereof unless and until a written notice of the
assignment, negotiation or transfer thereof shall have been given to the Agent
in accordance with the provisions of this Agreement. The Agent shall be entitled
to refrain from taking or omitting to take any action in connection with this
Agreement or any other Credit Document (i) if such action or omission would, in
the reasonable opinion of the Agent, violate any applicable law or any provision
of this Agreement or any other Credit Document or (ii) unless and until it shall
have received such advice or concurrence of the Required Lenders (or, where a
higher percentage of the Lenders is expressly required hereunder, such Lenders)
as it deems appropriate or it shall first have been indemnified to its
satisfaction by the Lenders against any and all liability and expense (other
than liability and expense arising from its own gross negligence or willful
misconduct) that may be incurred by it by reason of taking, continuing to take
or omitting to take any such action. Without limiting the foregoing, no Lender
shall have any right of action whatsoever against the Agent as a result of the
Agent's acting or refraining from acting hereunder or under any other Credit
Document in accordance with the instructions of the Required Lenders (or, where
a higher percentage of the Lenders is expressly required hereunder, such
Lenders), and such instructions and any action taken or failure to act pursuant
thereto shall be binding upon all of the Lenders (including all subsequent
Lenders).

         9.5 Non-Reliance on Agent and Other Lenders. Each Lender expressly
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representation
or warranty to it and that no act by the Agent or any such Person hereinafter
taken, including any review of the affairs of the Borrower and its Subsidiaries,
shall be deemed to constitute any representation or warranty by the Agent to any
Lender. Each Lender represents to the Agent that (i) it has, independently and
without reliance upon the Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, properties, financial
and other condition and creditworthiness of the Borrower and its Subsidiaries
and made its own decision to enter into this Agreement and extend credit to the
Borrower hereunder, and (ii) it will, independently and without reliance upon
the Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action hereunder and under the
other Credit Documents and to make such investigation as it deems necessary to
inform itself as to the business, prospects, operations, properties, financial
and other condition and creditworthiness of the Borrower and its Subsidiaries.
Except as expressly provided in this Agreement and the other Credit Documents,
the Agent shall have no duty or responsibility, either initially or on a
continuing basis, to provide any Lender with any credit or other information
concerning the business, prospects, operations, properties, financial or other
condition or creditworthiness of the Borrower, its Subsidiaries or any other
Person that may at any time come into the possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.




                                       64
<PAGE>   66

         9.6 Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default unless the Agent
shall have received written notice from the Borrower or a Lender referring to
this Agreement, describing such Default or Event of Default and stating that
such notice is a "notice of default." In the event that the Agent receives such
a notice, the Agent will give notice thereof to the Lenders as soon as
reasonably practicable; provided, however, that if any such notice has also been
furnished to the Lenders, the Agent shall have no obligation to notify the
Lenders with respect thereto. The Agent shall (subject to SECTIONS 9.4 and 10.6)
take such action with respect to such Default or Event of Default as shall
reasonably be directed by the Required Lenders; provided that, unless and until
the Agent shall have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interests of the Lenders.

         9.7 Indemnification. To the extent the Agent is not reimbursed by or on
behalf of the Borrower, and without limiting the obligation of the Borrower to
do so, the Lenders agree (i) to indemnify the Agent and its officers, directors,
employees, agents, attorneys-in-fact and Affiliates, ratably in proportion to
their respective percentages as used in determining the Required Lenders as of
the date of determination, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including, without limitation, attorneys' fees and expenses) or
disbursements of any kind or nature whatsoever that may at any time (including,
without limitation, at any time following the repayment in full of the Loans and
the termination of the Commitments) be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement or any
other Credit Document or any documents contemplated by or referred to herein or
the transactions contemplated hereby or thereby or any action taken or omitted
by the Agent under or in connection with any of the foregoing, and (ii) to
reimburse the Agent upon demand, ratably in proportion to their respective
percentages as used in determining the Required Lenders as of the date of
determination, for any expenses incurred by the Agent in connection with the
preparation, negotiation, execution, delivery, administration, amendment,
modification, waiver or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement or any of the other Credit Documents
(including, without limitation, reasonable attorneys' fees and expenses and
compensation of agents and employees paid for services rendered on behalf of the
Lenders); provided, however, that no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements to the extent resulting from the gross
negligence or willful misconduct of the party to be indemnified.

         9.8 The Agent in its Individual Capacity. With respect to its
Commitment, the Loans made by it and the Note or Notes issued to it, the Agent
in its individual capacity and not as Agent shall have the same rights and
powers under the Credit Documents as any other Lender and may exercise the same
as though it were not performing the agency duties specified herein; and the
terms "Lenders," "Required Lenders," "holders of Notes" and any similar terms
shall, unless the context clearly otherwise indicates, include the Agent in its
individual capacity. The Agent and its Affiliates may accept deposits from, lend
money to, make investments in, and generally engage in any kind of banking,
trust, financial advisory or other business with the Borrower, any of its
Subsidiaries or any of their respective Affiliates as if the Agent were not






                                       65
<PAGE>   67

performing the agency duties specified herein, and may accept fees and other
consideration from any of them for services in connection with this Agreement
and otherwise without having to account for the same to the Lenders.

         9.9 Successor Agent. The Agent may resign at any time by giving ten
(10) days' prior written notice to the Borrower and the Lenders, provided that,
subject to the last sentence of this section, such resignation shall not be
effective until a successor Agent shall have accepted the appointment. Upon any
notice of resignation by the Agent, the Required Lenders will, with the prior
written consent of the Borrower (which consent shall not be unreasonably
withheld), appoint from among the Lenders a successor to the Agent (provided
that the Borrower's consent shall not be required in the event a Default or
Event of Default shall have occurred and be continuing). If no successor to the
Agent shall have been so appointed by the Required Lenders and shall have
accepted such appointment within such ten-day period, then the retiring Agent
may, on behalf of the Lenders and after consulting with the Lenders and the
Borrower, appoint a successor Agent from among the Lenders. Upon the acceptance
of any appointment as Agent by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder and under the other Credit Documents.
After any retiring Agent's resignation as Agent, the provisions of this Article
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent. If no successor to the Agent has accepted appointment as
Agent by the thirtieth (30th) day following a retiring Agent's notice of
resignation, the retiring Agent's resignation shall nevertheless thereupon
become effective, and the Lenders shall thereafter perform all of the duties of
the Agent hereunder and under the other Credit Documents until such time, if
any, as the Required Lenders appoint a successor Agent as provided for
hereinabove.

         9.10     Collateral Matters.

         (a) The Agent is hereby authorized on behalf of the Lenders, without
the necessity of any notice to or further consent from the Lenders, from time to
time (but without any obligation) to take any action with respect to the
Collateral and the Security Documents that may be necessary to perfect and
maintain perfected the Liens upon the Collateral granted pursuant to the
Security 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 in full of all of
the Obligations, (ii) constituting property sold or to be sold or disposed of as
part of or in connection with any disposition expressly permitted hereunder or
under any other Credit Document or to which the Required Lenders have consented
or (iii) otherwise pursuant to and in accordance with the provisions of any
applicable Credit Document. Upon request by the Agent at any time, the Lenders
will confirm in writing the Agent's authority to release Collateral pursuant to
this subsection (b).

and the preparation, negotiation, execution, delivery and syndication of, this
Agreement and the other Credit Documents, and any amendment, modification or
waiver hereof or thereof or consent with respect hereto or thereto, (x) the
administration, monitoring and review of the Loans and the Collateral
(including, without limitation, out-of-pocket expenses for travel, meals,
long-distance telephone calls, wire transfers, facsimile transmissions and
copying and with respect to the engagement of appraisers, consultants, auditors
or similar Persons by the Agent at any time, whether before or after the
Closing, to render opinions concerning the Borrower's financial condition and
the value of the Collateral), (y) any attempt to inspect, verify, protect,
collect, sell, liquidate or otherwise dispose of any Collateral and (z) the
creation, perfection and maintenance of the perfection of the Agent's Liens upon
the Collateral, including, without limitation, Lien search, filing and recording
fees, (ii) to pay upon demand all reasonable out-of-pocket costs and expenses of
the Agent and each Lender (including, without limitation, reasonable attorneys'
fees and expenses) in connection with (y) any refinancing or restructuring of
the credit arrangement provided under this Agreement, whether in the nature of a
"work-out," in any insolvency or bankruptcy proceeding or otherwise and whether
or not consummated, and (z) the enforcement, attempted enforcement or
preservation of any rights or remedies under this Agreement or any of the other
Credit Documents, whether in any action, suit or proceeding (including any
bankruptcy or insolvency proceeding) or otherwise, and (iii) to pay and hold the
Agent and each Lender harmless from and against all liability for any
intangibles, documentary, stamp or other similar taxes, fees and excises, if
any, including any interest and penalties, and any finder's or brokerage fees,

finders or brokers engaged by the Agent or any Lender), that may be payable in
connection with the transactions contemplated by this Agreement and the other
Credit Documents.

         10.2 Indemnification. The Borrower agrees, whether or not the
transactions contemplated by this Agreement shall be consummated, to indemnify
and hold the Agent and each Lender and each of their respective directors,
officers, employees, agents and Affiliates (each, an "Indemnified Person")
harmless from and against any and all claims, losses, damages, obligations,
liabilities, penalties, costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses) of any kind or nature whatsoever,
whether direct, indirect or consequential (collectively, "Indemnified Costs"),
that may at any time be imposed on, incurred by or asserted against any such
Indemnified Person as a result of, arising from or in any way relating to the
preparation, execution, performance or enforcement of this Agreement or any of
the other Credit Documents, any of the transactions contemplated herein or
therein or any transaction financed or to be financed in whole or in part,
directly or indirectly, with the proceeds of any Loans (including, without
limitation, in connection with the actual or alleged generation, presence,
discharge or release of any Hazardous Substances on, into or from, or the

transportation of Hazardous Substances to or from, any real property at any time
owned or leased by the Borrower or any of its Subsidiaries, any other
Environmental Claims or any violation of or liability under any Environmental
Law), or any action, suit or proceeding (including any inquiry or investigation)
by any Person, whether threatened or initiated, related to any of the foregoing,
and in any case whether or not such Indemnified Person is a party to any such
action, proceeding or suit or a subject of any such inquiry or investigation;
provided, however, that no Indemnified Person shall have the right to be
indemnified hereunder for any Indemnified Costs to the extent resulting from the
gross negligence or willful misconduct of such Indemnified Person. All of the
foregoing Indemnified Costs of any Indemnified Person shall be paid or
reimbursed by the Borrower, as and when incurred and upon demand.

         10.3 Governing Law; Consent to Jurisdiction. THIS AGREEMENT AND THE
OTHER CREDIT DOCUMENTS HAVE BEEN EXECUTED, DELIVERED AND ACCEPTED IN, AND SHALL
BE DEEMED TO HAVE BEEN MADE IN, NORTH CAROLINA AND SHALL BE GOVERNED BY AND
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH
CAROLINA (WITHOUT REGARD TO THE CONFLICTS OF LAW PROVISIONS THEREOF). THE
BORROWER HEREBY CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF ANY STATE COURT
WITHIN MECKLENBURG COUNTY, NORTH CAROLINA OR ANY FEDERAL COURT LOCATED WITHIN
THE WESTERN DISTRICT OF THE STATE OF NORTH CAROLINA FOR ANY PROCEEDING
INSTITUTED HEREUNDER OR UNDER ANY OF THE OTHER CREDIT DOCUMENTS, OR ARISING OUT
OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS, OR
ANY PROCEEDING TO WHICH THE AGENT OR ANY LENDER OR THE BORROWER IS A PARTY,
INCLUDING ANY ACTIONS BASED UPON, ARISING OUT OF, OR IN CONNECTION WITH ANY
COURSE OF CONDUCT, COURSE OF DEALING, STATEMENT (WHETHER ORAL OR WRITTEN) OR
ACTIONS OF THE AGENT OR ANY LENDER OR THE BORROWER. THE BORROWER IRREVOCABLY
AGREES TO BE BOUND (SUBJECT TO ANY AVAILABLE RIGHT OF APPEAL) BY ANY JUDGMENT
RENDERED OR RELIEF GRANTED THEREBY AND FURTHER WAIVES ANY OBJECTION THAT IT MAY
HAVE BASED ON LACK OF JURISDICTION OR IMPROPER VENUE OR FORUM NON CONVENIENS TO
THE CONDUCT OF ANY SUCH PROCEEDING. THE BORROWER CONSENTS THAT ALL SERVICE OF
PROCESS BE MADE BY REGISTERED OR CERTIFIED MAIL DIRECTED TO IT AT ITS ADDRESS
SET FORTH HEREINBELOW, AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED UPON
THE EARLIER OF ACTUAL RECEIPT THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE
UNITED STATES MAILS, PROPER POSTAGE PREPAID AND PROPERLY ADDRESSED. NOTHING IN
THIS SECTION SHALL AFFECT THE RIGHT TO SERVE LEGAL PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR AFFECT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING ANY
ACTION OR PROCEEDING AGAINST THE BORROWER IN THE COURTS OF ANY OTHER
JURISDICTION.

         10.4     Arbitration; Preservation and Limitation of Remedies.

         (a) Upon demand of any party hereto, whether made before or after
institution of any judicial proceeding, any dispute, claim or controversy
arising out of, connected with or relating to this Agreement or any other Credit






                                       68
<PAGE>   70

Document ("Disputes") between or among the Borrower, its Subsidiaries, the Agent
and the Lenders, or any of them, shall be resolved by binding arbitration as
provided herein. Institution of a judicial proceeding by a party does not waive
the right of that party to demand arbitration hereunder. Disputes may include,
without limitation, tort claims, counterclaims, claims brought as class actions,
claims arising from documents executed in the future, or claims arising out of
or connected with the transactions contemplated by this Agreement and the other
Credit Documents. Arbitration shall be conducted under and governed by the
Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of the
American Arbitration Association (the "AAA"), as in effect from time to time,
and Title 9 of the U.S. Code, as amended. All arbitration hearings shall be
conducted in the city in which the principal office of the Agent is located. The
expedited procedures set forth in Rule 51 et seq. of the Arbitration Rules shall
be applicable to claims of less than $1,000,000. All applicable statutes of
limitation shall apply to any Dispute. A judgment upon the award may be entered
in any court having jurisdiction. The panel from which all arbitrators are
selected shall be comprised of licensed attorneys. The single arbitrator
selected for expedited procedure shall be a retired judge from the highest court
of general jurisdiction, state or federal, of the state where the hearing will
be conducted. Notwithstanding the foregoing, this arbitration provision does not
apply to Disputes under or related to Hedge Agreements. The parties do not waive
applicable federal or state substantive law except as provided herein.

         (b) Notwithstanding the preceding binding arbitration provisions, the
parties hereto agree to preserve, without diminution, certain remedies that any
party hereto may employ or exercise freely, either alone, in conjunction with or
during a Dispute. Any party hereto shall have the right to proceed in any court
of proper jurisdiction or by self-help to exercise or prosecute the following
remedies, as applicable: (i) all rights to foreclose against any Collateral by
exercising a power of sale granted pursuant to any of the Credit Documents or
under applicable law or by judicial foreclosure and sale, including a proceeding
to confirm the sale; (ii) all rights of self-help, including peaceful occupation
of real property and collection of rents, set-off, and peaceful possession of
personal property; (iii) obtaining provisional or ancillary remedies, including
injunctive relief, sequestration, garnishment, attachment, appointment of a
receiver and filing an involuntary bankruptcy proceeding; and (iv) when
applicable, a judgment by confession of judgment. Preservation of these remedies
does not limit the power of an arbitrator to grant similar remedies that may be
requested by a party in a Dispute. The parties hereto agree that no party shall
have a remedy of punitive or exemplary damages against any other party in any
Dispute, and each party hereby waives any right or claim to punitive or
exemplary damages that it has now or that may arise in the future in connection
with any Dispute, whether such Dispute is resolved by arbitration or judicially.
The parties acknowledge that by agreeing to binding arbitration they have
irrevocably waived any right they may have to a jury trial with regard to a
Dispute.

         10.5 Notices. All notices and other communications provided for
hereunder shall be in writing (including telegraphic, telex, facsimile
transmission or cable communication) and mailed, telegraphed, telexed,

unless in a writing signed by the Required Lenders (or by the Agent at the
direction or with the consent of the Required Lenders), and then the same shall
be effective only in the specific instance and for the specific purpose for
which given; provided, however, that no such amendment, modification, waiver,
discharge, termination or consent shall:

         (a) unless agreed to by each Lender directly affected thereby, (i)

forgive any interest thereon, or reduce or forgive any fees or other Obligations
(other than fees payable to the Agent for its own account), or (ii) extend the

interest on any Loan (other than additional interest payable under SECTION
2.8(B) at the election of the Required Lenders, as provided therein), any fees
(other than fees payable to the Agent for its own account) or any other
Obligations;

         (b) unless agreed to by all of the Lenders, (i) increase or extend any
Commitment of any Lender (it being understood that a waiver of any Event of
Default, if agreed to by the requisite Lenders hereunder, shall not constitute
such an increase), (ii) change the percentage of the aggregate Commitments or of
the aggregate unpaid principal amount of the Loans, or the number or percentage
of Lenders, that shall be required for the Lenders or any of them to take or
approve, or direct the Agent to take, any action hereunder (including as set
forth in the definition of "Required Lenders"), (iii) except as may be otherwise
specifically provided in this Agreement or in any other Credit Document, release






                                       70
<PAGE>   72

all or substantially all of the Collateral or release any Subsidiary Guarantor
from its obligations under the Subsidiary Guaranty, or (iv) change any provision
of SECTION 2.15 or this Section; and

         (c) unless agreed to by the Agent in addition to the Lenders required
as provided hereinabove to take such action, affect the rights or obligations of
the Agent, as applicable, hereunder or under any of the other Credit Documents;

and provided further that the Fee Letter may be amended or modified, and any
rights thereunder waived, in a writing signed by the parties thereto.

         10.7     Assignments, Participations.

         (a) Each Lender may assign to one or more other Eligible Assignees
(each, an "Assignee") all or a portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Commitments,
the outstanding Loans made by it and the Note or Notes held by it; provided,
however, that (i) any such assignment (other than an assignment to a Lender or
an Affiliate of a Lender) shall not be made without the prior written consent of
the Agent and the Borrower (to be evidenced by its counterexecution of the
relevant Assignment and Acceptance), which consent shall not be unreasonably
withheld (provided that the Borrower's consent shall not be required in the
event a Default or Event of Default shall have occurred and be continuing), (ii)
each such assignment shall be of a uniform, and not varying, percentage of all
of the assigning Lender's rights and obligations under this Agreement, (iii)
except in the case of an assignment to a Lender or an Affiliate of a Lender, no
such assignment shall be in an aggregate principal amount (determined as of the
date of the Assignment and Acceptance with respect to such assignment) less than
$5,000,000, determined by combining the amount of the assigning Lender's
outstanding Loans and Unutilized Commitment being assigned pursuant to such
assignment (or, if less, the entire Commitment of the assigning Lender) and (iv)
the parties to each such assignment will execute and deliver to the Agent, for
its acceptance and recording in the Register, an Assignment and Acceptance,
together with any Note or Notes subject to such assignment, and will pay a
nonrefundable processing fee of $3,000 to the Agent for its own account. Upon
such execution, delivery, acceptance and recording of the Assignment and
Acceptance, from and after the effective date specified therein, which effective
date shall be at least five Business Days after the execution thereof (unless
the Agent shall otherwise agree), (A) the Assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, shall have the rights
and obligations of the assigning Lender hereunder with respect thereto and (B)
the assigning Lender shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights (other than rights under the provisions of this Agreement and the
other Credit Documents relating to indemnification or payment of fees, costs and
expenses, to the extent such rights relate to the time prior to the effective
date of such Assignment and Acceptance) and be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all or the remaining portion of such assigning Lender's rights and obligations
under this Agreement, such Lender shall cease to be a party hereto). The terms
and provisions of each Assignment and Acceptance shall, upon the effectiveness






                                       71
<PAGE>   73

thereof, be incorporated into and made a part of this Agreement, and the
covenants, agreements and obligations of each Lender set forth therein shall be
deemed made to and for the benefit of the Agent and the other parties hereto as
if set forth at length herein.

         (b) The Agent will maintain at its address for notices referred to
herein a copy of each Assignment and Acceptance delivered to and accepted by it
and a register for the recordation of the names and addresses of the Lenders and
the Commitments of, and principal amount of the Loans owing to, each Lender from
time to time (the "Register"). The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and 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 shall be
available for inspection by the Borrower and each Lender at any reasonable time
and from time to time upon reasonable prior notice.

         (c) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an Assignee and, if required,
counterexecuted by the Borrower, together with the Note or Notes subject to such
assignment and the processing fee referred to in subsection (a) above, the Agent
will (i) accept such Assignment and Acceptance, (ii) on the effective date
thereof, record the information contained therein in the Register and (iii) give
notice thereof to the Borrower and the Lenders. Within five (5) Business Days
after its receipt of such notice, the Borrower, at its own expense, will execute
and deliver to the Agent, in exchange for the surrendered Note or Notes, a new
Note or Notes to the order of the Assignee (and, if the assigning Lender has
retained any portion of its rights and obligations hereunder, to the order of
the assigning Lender), prepared in accordance with the applicable provisions of
SECTION 2.4 as necessary to reflect, after giving effect to the assignment, the
Commitments of the Assignee and (to the extent of any retained interests) the
assigning Lender, dated the date of the replaced Note or Notes and otherwise in
substantially the form of EXHIBIT A. The Agent will return cancelled Notes to
the Borrower.

         (d) Each Lender may, without the consent of the Borrower, the Agent or
any other Lender, sell to one or more other Persons (each, a "Participant")
participations in any portion comprising less than all of its rights and
obligations under this Agreement (including, without limitation, a portion of
its Commitments, the outstanding Loans made by it and the Note or Notes held by
it; provided, however, that (i) such Lender's obligations under this Agreement
shall remain unchanged and such Lender shall remain solely responsible for the
performance of such obligations, (ii) no Lender shall sell any participation
that, when taken together with all other participations, if any, sold by such
Lender, covers all of such Lender's rights and obligations under this Agreement,
(iii) the Borrower, the Agent and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and no Lender shall permit any Participant to
have any voting rights or any right to control the vote of such Lender with
respect to any amendment, modification, waiver, consent or other action
hereunder or under any other Credit Document (except as to actions that would
(x) reduce or forgive the principal amount of any Loan, reduce the rate of or
forgive any interest thereon, or reduce or forgive any fees or other
Obligations, (y) extend the Maturity Date or any other date fixed for the
payment of any principal of or interest on any Loan, any fees or any other
Obligations, or (z) increase or extend any Commitment of any Lender), and (iv)
no Participant shall have any rights under this Agreement or any of the other
Credit Documents, each Participant's rights against the granting Lender in
respect of any participation to be those set forth in the participation






                                       72
<PAGE>   74

agreement, and all amounts payable by the Borrower hereunder shall be determined
as if such Lender had not granted such participation. Notwithstanding the
foregoing, each Participant shall have the rights of a Lender for purposes of
SECTIONS 2.16(A), 2.16(B), 2.17, 2.18 and 8.3, and shall be entitled to the
benefits thereto, to the extent that the Lender granting such participation
would be entitled to such benefits if the participation had not been made,
provided that no Participant shall be entitled to receive any greater amount
pursuant to any of such Sections than the Lender granting such participation
would have been entitled to receive in respect of the amount of the
participation made by such Lender to such Participant had such participation not
been made.

         (e) Nothing in this Agreement shall be construed to prohibit any Lender
from pledging or assigning all or any portion of its rights and interest
hereunder or under any Note to any Federal Reserve Bank as security for
borrowings therefrom; provided, however, that no such pledge or assignment shall
release a Lender from any of its obligations hereunder.

         (f) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section,
disclose to the Assignee or Participant or proposed Assignee or Participant any
information relating to the Borrower and its Subsidiaries furnished to it by or
on behalf of any other party hereto, provided that such Assignee or Participant
or proposed Assignee or Participant agrees in writing to keep such information
confidential to the same extent required of the Lenders under SECTION 10.13.

         10.8 No Waiver. The rights and remedies of the Agent and the Lenders
expressly set forth in this Agreement and the other Credit Documents are
cumulative and in addition to, and not exclusive of, all other rights and
remedies available at law, in equity or otherwise. No failure or delay on the
part of the Agent or any Lender in exercising any right, power or privilege
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right, power or privilege preclude other or further exercise thereof or
the exercise of any other right, power or privilege or be construed to be a
waiver of any Default or Event of Default. No course of dealing between any of
the Borrower and the Agent or the Lenders or their agents or employees shall be
effective to amend, modify or discharge any provision of this Agreement or any
other Credit Document or to constitute a waiver of any Default or Event of
Default. No notice to or demand upon the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the right of the Agent or any Lender to
exercise any right or remedy or take any other or further action in any
circumstances without notice or demand.

         10.9 Successors and Assigns. This Agreement shall be binding upon,
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto, and all references herein to any party shall be
deemed to include its successors and assigns; provided, however, that (i) the
Borrower shall not sell, assign or transfer any of its rights, interests, duties
or obligations under this Agreement without the prior written consent of all of
the Lenders and (ii) any Assignees and Participants shall have such rights and
obligations with respect to this Agreement and the other Credit Documents as are
provided for under and pursuant to the provisions of SECTION 10.7.

         10.10 Survival. All representations, warranties and agreements made by
or on behalf of the Borrower or any of its Subsidiaries in this Agreement and in
the other Credit Documents shall survive the execution and delivery hereof or
thereof and the making and repayment of the Loans. In addition, notwithstanding
anything herein or under applicable law to the contrary, the provisions of this
Agreement and the other Credit Documents relating to indemnification or payment
of fees, costs and expenses, including, without limitation, the provisions of
SECTIONS 2.16(A), 2.16(B), 2.17, 2.18, 9.7, 10.1 and 10.2, shall survive the
payment in full of all Loans, the termination of the Commitments and any
termination of this Agreement or any of the other Credit Documents.

         10.11 Severability. To the extent any provision of this Agreement is
prohibited by or invalid under the applicable law of any jurisdiction, such
provision shall be ineffective only to the extent of such prohibition or
invalidity and only in such jurisdiction, without prohibiting or invalidating
such provision in any other jurisdiction or the remaining provisions of this
Agreement in any jurisdiction.

         10.12 Construction. The headings of the various articles, sections and
subsections of this Agreement have been inserted for convenience only and shall
not in any way affect the meaning or construction of any of the provisions
hereof. Except as otherwise expressly provided herein and in the other Credit
Documents, in the event of any inconsistency or conflict between any provision
of this Agreement and any provision of any of the other Credit Documents, the
provision of this Agreement shall control.

         10.13 Confidentiality. Each Lender agrees to keep confidential,
pursuant to its customary procedures for handling confidential information of a
similar nature and in accordance with safe and sound banking practices, all
nonpublic information provided to it by or on behalf of the Borrower or any of
its Subsidiaries in connection with this Agreement or any other Credit Document;
provided, however, that any Lender may disclose such information (i) to its
directors, employees, agents and affiliates and to its auditors, counsel and
other professional advisors, provided that such persons shall be subject to this
SECTION 10.13, (ii) at the demand or request of any bank regulatory authority,
court or other Governmental Authority having or asserting jurisdiction over such
Lender, as may be required pursuant to subpoena or other legal process, or
otherwise in order to comply with any applicable Requirement of Law, (iii) in
connection with any proceeding to enforce its rights hereunder or under any
other Credit Document or any other litigation or proceeding related hereto or to
which it is a party, (iv) to the Agent or any other Lender, (v) to the extent
the same has become publicly available other than as a result of a breach of
this Agreement and (vi) pursuant to and in accordance with the provisions of
SECTION 10.7(F).

         10.14 Counterparts; Effectiveness. This Agreement may be executed in
any number of counterparts and by different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original,
but all of which shall together constitute one and the same instrument. This
Agreement shall become effective upon the execution of a counterpart hereof by
each of the parties hereto and receipt by the Agent and the Borrower of written
or telephonic notification of such execution and authorization of delivery
thereof.

Sheets and other similar bank trade publications. Such information will consist
of deal terms and other information customarily found in such publications.

INSTRUMENTS EXECUTED AND DELIVERED IN CONNECTION HEREWITH (A) EMBODY THE ENTIRE

LETTER FROM FIRST UNION TO THE BORROWER DATED FEBRUARY 17, 1999, BUT

CONTRADICTED OR OTHERWISE MODIFIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
