CLINTRIALS RESEARCH INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of
ClinTrials Research Inc. (the "Company") have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for fair presentation have been included. Certain
prior year amounts have been reclassified to conform to the current year
presentation. Operating results for the three months ended March 31, 1998, are
not necessarily indicative of the results that may be expected for other
quarters or the entire year. For further information, refer to the consolidated
financial statements and footnotes thereto included in the Company's annual
report on Form 10-K for the year ended December 31, 1997.

On June 1, 1997, the Company completed a merger with Ovation Healthcare
Research, Incorporated ("Ovation"), a privately held pharmacoeconomic and
consulting firm based in Highland Park, Illinois. The Company issued 250,000
shares of its common stock in the merger transaction, which was accounted for as
a pooling of interests and, accordingly, the accompanying condensed consolidated
financial statements give retroactive effect to the merger and include the
combined operations of the Company and Ovation.

NOTE 2 -EARNINGS (LOSS) PER SHARE

The Company adopted Financial Accounting Standards Board Statement of Financial
Accounting Standards No. 128, "Earnings per Share" ("SFAS No. 128") on December
31, 1997. SFAS No. 128 requires presentation of both Basic Earnings per Share
("Basic EPS") and Diluted Earnings per Share ("Diluted EPS"). Basic EPS is based
on the weighted average number of shares of common stock outstanding during the
year. Diluted EPS also includes the dilutive effect of common stock equivalents,
which consists of stock options representing 405,000 equivalent shares for the
three months ended March 31, 1997. Diluted loss per share for the three months
ended March 31, 1998 does not include common stock equivalents of 276,000 as
their effect would be anti-dilutive. Prior period earnings per share amounts
have been restated to present Basic EPS and Diluted EPS. The Company's stock is
currently traded in the Nasdaq Stock Market and sale information is included on
the Nasdaq National Market Issues System under the symbol "CCRO".

NOTE 3 -COMPREHENSIVE INCOME (LOSS)

The Company adopted Financial Accounting Standards Board Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130")
on January 1, 1998. SFAS No. 130 establishes new rules for reporting and
displaying comprehensive income and its components; however, the adoption of
SFAS No. 130 has no impact on the Company's net income or stockholders' equity.
SFAS No. 130 requires the Company to include foreign currency translation
adjustments, which were previously reported by the Company as a separate
component of stockholders' equity, in other comprehensive income. Accumulated
other comprehensive income consists entirely of accumulated foreign currency
translation adjustments and is a separate


                                       4

<PAGE>   7


component of stockholders' equity under SFAS No. 130. Prior period amounts have
been reclassified to conform to the requirements of SFAS No. 130.

The components of comprehensive income (loss), net of related tax, for the three
months ended March 31 are as follows (in thousands):

</TABLE>


NOTE 4 -PROVISION (BENEFIT) FOR INCOME TAXES

The effective tax benefit rate was 38.3% for the three months ended March 31,
1998, compared to an effective tax rate of 14.1% for the three months ended
March 31, 1997. The effective tax benefit rate for the 1998 period is primarily
the result of the tax benefit associated with operating losses combined with
research and development tax credits generated by the Company's Canadian
subsidiary, while the effective tax rate for the 1997 period was primarily the
result of the provision for income taxes partially offset by such research and
development tax credits. Significant items that create the difference between
the Company's federal statutory and effective tax rates are state and local
taxes and nondeductible amortization of goodwill. The Company, in general, will
not record a tax asset related to a foreign jurisdiction for losses incurred in
its foreign operations until such time, if any, that it has three years of
profits in the applicable jurisdiction. However, the Company will recognize a
tax benefit for losses incurred in its foreign operations as the subsidiary
generates taxable income to the extent of the cumulative losses.

NOTE 5 -LONG-TERM DEBT

In March 1998, the Company replaced its $10.0 million domestic credit facility
with a $15.0 million domestic credit facility which has expansion capabilities
to $40.0 million. Credit availability under the Company's new domestic line of
credit and its foreign line of credit ("Credit Facilities") totals approximately
$18.5 million. The lines are collateralized by certain of the Company's assets
and bear interest at a fluctuating rate based either on the respective bank's
prime interest rate or the London Interbank Offered Rate ("LIBOR"), as elected
by the Company. On March 31, 1998, there were no borrowings outstanding under
the lines of credit. Commitment availability at March 31, 1998 has been reduced
by issued letters of credit of approximately $750,000. Borrowings available
under the lines of credit are subject to certain financial and operating
covenants.

In March 1998, the Company's Canadian subsidiary borrowed approximately $382,000
from the Canadian government. This borrowing bears no interest and is repayable
in four annual installments beginning in 1999.

NOTE 6 -CONTINGENCIES

In 1991, a customer commenced legal action against the predecessor of the
Company's preclinical subsidiary claiming damages resulting from statistical
errors in carrying out two research studies. Judgment was rendered in February
1997 by the Superior Court of Montreal against the Company's preclinical
subsidiary in the amount of approximately $560,000 plus interest to accrue from
September 1991. The Company's preclinical subsidiary, now responsible for this
action, has reserves adequate to cover the current judgment amount. The
Company's preclinical subsidiary has appealed the amount of the judgment and the
subsidiary's insurance company has appealed the portion of the judgment which
obligates the insurance company to pay the insurance claim related to this
litigation. The Company believes it is entitled, subject to certain limitations,
to indemnification from a former owner of the predecessor for a portion of this
claim. In the opinion of management, the ultimate resolution of such pending
legal proceedings will not have a material effect on the Company's financial
position or results of operations.

NOTE 7 -RESTRUCTURING CHARGES

In the fourth quarter of 1997, the Company determined that its current revenue
levels would not support its general and administrative cost structure. As a
result, the Company accrued $1.6 million at December 31, 1997, for restructuring
costs to be incurred in 1998 in reducing its administrative workforce, primarily
in Europe. In the first quarter of 1998, the Company paid $852,000 of the
restructuring costs, primarily in severance costs to approximately 30
employees. At March 31, 1998, $798,000 remains in accrued expenses for
restructuring costs expected to be paid over the remainder of 1998.

On April 24, 1998, the Company announced that its data management operations in
Lexington, Kentucky will be consolidated into its new clinical research center
in Research Triangle Park, North Carolina. In connection with the closing of the
Company=s Lexington facility, the Company will incur a restructuring charge
estimated to approximate $5.0 million for the write-off of goodwill, lease
costs, and involuntary termination benefits which will be recorded in the second
quarter of 1998.

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

The following discussion should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
included in the Company's annual report on Form 10-K for the year ended December
31, 1997.

The information set forth and discussed below for the three months ended March
31, 1998 and 1997 is derived from the Condensed Consolidated Financial
Statements included elsewhere herein. The financial information set forth and
discussed below is unaudited but, in the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. The Company's results of operations for a
particular quarter may not be indicative of the results that may be expected for
other quarters or the entire year.


                                       6
<PAGE>   9


The Company's Form 10-Q includes forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995, including, without
limitation, statements containing the words "believes," "anticipates,"
"intends," "expects" and words of similar import. Such statements include
statements concerning the Company's ability to obtain new business and to
accurately estimate the timing of recognition of revenue in the backlog due to
variability in size, scope and duration of projects, regulatory delays, study
results which lead to reductions or cancellations of projects, other decisions
totally within the control of its clients and its ability to immediately affect
the level of operating expenses, as well as statements concerning the Company's
business strategy, acquisition strategy, operations, cost savings initiatives,
industry, economic performance, financial condition, liquidity and capital
resources, existing government regulations and changes in, or the failure to
comply with, governmental regulations. Such statements are subject to various
risks and uncertainties. The Company's actual results may differ materially from
the results discussed in such forward-looking statements because of a number of
factors, including those identified in this Management's Discussion and Analysis
of Financial Condition and Results of Operations. Although the Company believes
that the assumptions underlying the forward-looking statements contained herein
are reasonable, any of the assumptions could be inaccurate, and therefore, there
can be no assurance that such statements included in this document will prove to
be accurate. In light of the significant uncertainties inherent in the
forward-looking statements included herein, the inclusion of such information
should not be regarded as a representation by the Company or any other person
that the objectives and plans of the Company will be achieved. The
forward-looking statements are made as of the date of this document and the
Company assumes no obligation to update such statements or to update the reasons
that actual results could differ from those projected in the forward-looking
statements.

OVERVIEW

The Company is a full-service contract research organization ("CRO") serving the
pharmaceutical, biotechnology and medical device industries. The Company
designs, monitors and manages preclinical and clinical trials, provides clinical
data management and biostatistical services and offers product registration and
pharmacoeconomic services throughout the United States, Canada and Europe. The
Company generates substantially all of its revenue from the preclinical and
clinical testing of new pharmaceutical and biotechnology products.

The Company's contracts are typically fixed-price, multi-year contracts that
usually require a portion of the contract amount to be paid at or near the time
the trial is initiated. The Company generally bills its clients upon the
completion of negotiated performance requirements and, to a lesser extent, on a
date certain basis. The Company's contracts generally may be terminated with or
without cause. In the event of termination, the Company is typically entitled to
all sums owed for work performed through the notice of termination and all costs
associated with termination of the study. In addition, at times some of the
Company's contracts provide for an early termination fee, the amount of which
usually declines as the trial progresses. Termination or delay in the
performance of a contract may occur for various reasons, including, but not
limited to, unexpected or undesired results, inadequate patient enrollment or
investigator recruitment, production problems resulting in shortages of the
drug, adverse patient reactions to the drug, or the client's decision to
de-emphasize a particular trial.

Revenue for contracts is recognized on a percentage of completion basis as work
is performed. Revenue is affected by the mix of trials conducted and the degree
to which labor and facilities are utilized. The Company


                                       7
<PAGE>   10


routinely subcontracts with third party investigators in connection with
multi-site clinical trials and with other third party service providers for
laboratory analysis and other specialized services. These costs are passed
through to clients and, in accordance with industry practice, are included in
service revenue. Subcontractor services may vary significantly from contract to
contract; therefore, changes in gross service revenue may not be indicative of
trends in revenue growth. Accordingly, the Company views net service revenue,
which consists of service revenue less subcontractor costs, as its primary
measure of revenue growth. The Company has had, and will continue to have,
certain clients from which at least 10% of the Company's overall revenue is
generated over multiple contracts. Such concentrations of business are not
uncommon within the CRO industry.

The Company's core European operation consists of offices in Maidenhead, United
Kingdom and Brussels, Belgium. The Company expanded its ability to perform
international clinical trials by opening offices in Australia, Chile, France,
and Israel in 1996 and Italy and Scotland in 1997. The Company has made
significant investments in the marketing and infrastructure of its core European
operations; however, net revenue has not sufficiently grown to cover the
increased expense levels and in the fourth quarter of 1997 the Company decided
to reduce its general and administrative workforce (see restructuring charge
discussion below). The Company is focused on generating new business while
controlling its cost structure.

Contracts between the Company's subsidiaries (primarily in Canada and to a
lesser extent in the United Kingdom) and their clients may be denominated in a
currency other than the local currency of the subsidiary. Because substantially
all of the subsidiaries' expenses are paid in the local currency of the
subsidiary, such subsidiaries' earnings related to these contracts could be
affected by fluctuations in exchange rates. Generally, the Company attempts to
contractually limit its future foreign exchange risks with its clients. In
addition, the Company may use future foreign exchange contracts to hedge the
risk of changes in foreign currency exchange rates associated with contracts in
which the expenses for providing services are incurred in one currency and paid
for by the client in another currency. The Company's subsidiaries located
outside the United States generated approximately 50% of its net revenue for the
year ended December 31, 1997. More than half of the non U.S. revenue was
generated by the Company's Canadian subsidiary. Therefore, fluctuations in
exchange rates may have a material effect on the earnings of the Company.

The Company's consolidated financial statements are denominated in U.S. dollars
and, accordingly, changes in the exchange rates between the Company's
subsidiaries' local currency and the U.S. dollar will affect the translation of
such subsidiaries' financial results into U.S. dollars for purposes of reporting
the Company's consolidated financial results. Translation adjustments are
reported as a component of other comprehensive income (loss) in stockholders'
equity. Such adjustments may in the future be material to the Company's
financial statements.

RECENT DEVELOPMENTS

The Company developed a new business plan in April, 1998 which includes
consolidation of the Company's Lexington, Kentucky data management operations
into the Company's new clinical research center in Research Triangle Park, North
Carolina (see Restructuring Charges below); enhancement of the management team
with the recent hirings of individuals with extensive experience in clinical
drug development, information technology and


                                       8
<PAGE>   11


business development; implementation of a $3.0 million incremental capital
expenditure program to improve the Company's information technology platform;
and acceleration of marketing efforts for renewed growth of sales.

The Company's new business contracted in the first quarter of 1998 of $11.4
million was significantly less than expected, primarily as a result of lower
clinical sales as the Company focused on implementing the restructuring
announced in December 1997 and developing and implementing its new business plan
discussed above. As a result of previously announced contract cancellations in
the fourth quarter of 1996 and first quarter of 1997, a level of new orders
insufficient to cover these cancellations and the underperformance of the
Company's European operations, the Company incurred a loss in fiscal 1997 and
expects to incur a loss for fiscal 1998. With the Company's new business plan in
place, the Company is now concentrating its energies on generating new study
proposals, streamlining the proposal review process and improving customer
focus.

MERGER WITH OVATION

On June 1, 1997, the Company completed a merger with Ovation Healthcare
Research, Incorporated ("Ovation"), a privately held pharmacoeconomic and
consulting firm based in Highland Park, Illinois. The Company issued 250,000
shares of its Common Stock in the merger transaction, which was accounted for as
a pooling of interests and, accordingly, the accompanying consolidated financial
statements give retroactive effect to the merger and include the combined
operations of the Company and Ovation.

RESTRUCTURING CHARGES

In the fourth quarter of 1997, the Company determined that its current revenue
levels would not support its general and administrative cost structure. As a
result, the Company recorded a $1.6 million restructuring charge for costs to be
incurred in reducing its administrative workforce, primarily in Europe. At
December 31, 1997, the entire $1.6 million restructuring charge is included in
accrued expenses as no termination benefits were paid as of year end. In the
first quarter of 1998, the Company paid $852,000 of the restructuring costs,
primarily in severance costs to 30 employees. At March 31, 1998, approximately
$798,000 remains in accrued expenses for restructuring costs expected to be paid
over the remainder of 1998.

On April 24, 1998, the Company announced that its data management operations in
Lexington, Kentucky will be consolidated into its new clinical research center
in Research Triangle Park, North Carolina. In connection with the closing of the
Company's Lexington facility, the Company will incur a restructuring charge
estimated to approximate $5.0 million for the write-off of goodwill, lease costs
and involuntary termination benefits which will be recorded in the second
quarter of 1998.

RESULTS OF OPERATIONS

Three Months Ended March 31, 1998 Compared to Three Months Ended March 31, 1997

Net loss for the three months ended March 31, 1998 was $2.2 million, or $0.12
diluted loss per share, compared to net income in the same period of 1997 of
$0.7 million or $0.04 diluted earnings per share. This decrease is primarily
attributable to the cancellations of contracts, aggregating approximately $37
million in backlog, which


                                       9

<PAGE>   12


occurred in the fourth quarter of 1996 and first quarter of 1997, a level of new
orders insufficient to cover the previously noted cancellations and the
underperformance of the European operations. The decrease in backlog left the
Company with unbillable resources related to those projects as well as a higher
level of direct costs and selling, general and administrative expenses incurred
to cover the expected higher revenue levels. None of the cancellations were
related to service or quality problems. Due to the mix of contracts in backlog
and the underperformance of the Company's European operations, revenue
recognized was not sufficient to cover expenses and the Company incurred a loss
in the first quarter of 1998.

Net service revenue decreased 17.3% to $23.6 million in the 1998 period from
$28.6 million in 1997. This decrease resulted primarily from the cancellations
of contracts and a level of new orders insufficient to cover these cancellations
previously discussed.

Direct costs decreased 7.6% to $16.5 million in the three months ended March 31,
1998 from $17.9 million in the same period in 1997. Direct costs increased as a
percentage of net service revenue to 69.9% from 62.5% due to unbillable
resources resulting from the previously discussed project cancellations and
underperformance of the Company's European operations. Direct costs are based on
the mix of contracts in progress and as a percentage of net revenue may
fluctuate from period to period dependent upon the mix of contracts in the
backlog. In addition, direct costs will fluctuate due to changes in labor and
facility utilization.

Selling, general and administrative costs increased 8.2% to $9.6 million in the
three months ended March 31, 1998 from $8.9 million in the same period in 1997
primarily due to the opening of the Glasgow facility in November 1997 and
increases in lease costs. Selling, general and administrative costs increased as
a percentage of net service revenue to 40.7% from 31.1%. The increase as a
percentage of net revenue is primarily attributable to lower levels of revenue
resulting from project cancellations and underperformance of the European
operations. Selling, general and administrative costs, which primarily includes
compensation for administrative employees and costs related to facilities,
information technology and marketing, are relatively fixed in the near term
while revenue is subject to fluctuation, therefore, minor variations in the
timing of contracts or the progress of clinical trials (both delays and
accelerations) may cause significant variations in quarterly operating results.
In addition, the Company has incurred and will continue to incur costs related
to expanded infrastructure required to open new offices or expand existing
offices as described previously.

Depreciation and amortization expense increased 12.4% to $1.5 million in the
three months ended March 31, 1998 compared to $1.3 million in the same period in
1997.

Interest income, net of interest expense, was $328,000 in the first quarter of
1998 compared to $342,000 in the same period of 1997.

The Company's benefit for income taxes was $1.4 million in the three months
ended March 31, 1998 as compared to a provision of $0.1 million in the first
quarter of 1997. The effective tax benefit rate in 1998 was 38.3% compared to an
effective tax rate of 14.1% in 1997. The effective tax benefit rate for the 1998
period is primarily the result of the tax benefit associated with operating
losses combined with research and development tax credits generated by the
Company's Canadian subsidiary, while the effective tax rate for the 1997 period
was primarily the result of the provision for income taxes partially offset by
such research and development tax credits. Other


                                       10

<PAGE>   13


significant items that create the difference between the Company's federal
statutory and effective tax rates are state and local taxes and nondeductible
amortization of goodwill. The Company, in general, will not record a tax asset
related to a foreign jurisdiction for losses incurred in its foreign operations
until such time, if any, that it has three years of profits in the applicable
jurisdiction. However, the Company will recognize a tax benefit for losses
incurred in its foreign operations as the subsidiary generates taxable income to
the extent of the cumulative losses.

LIQUIDITY AND CAPITAL RESOURCES

The Company's primary operating cash needs on both a short-term and long-term
basis are the payment of salaries, office rent and travel expenses, as well as
capital expenditures. The Company has historically financed these expenditures,
as well as acquisitions, with cash flow from operations, issuances of equity
securities and borrowings under its Credit Facilities as defined below. The
Company utilizes its working capital to finance these expenditures pending
receipt of its receivables. Contract receipts from the Company's clients vary
according to the terms of each contract.

The Company's contracts usually require a portion of the contract amount to be
paid at or near the time the trial is initiated. Payments are generally received
upon the completion of negotiated performance requirements and, to a lesser
extent, on a date certain basis throughout the life of the contract. Cash
receipts do not correspond to costs incurred and revenue recognition (which is
based on cost-to-cost type of percentage of completion accounting). Therefore,
the Company's cash flow is influenced by the interaction of changes in
receivables and advance billings. The Company typically receives a low volume of
large-dollar cash receipts.

The Company has experienced a trend, which it expects will continue, in which
clients place less emphasis on prepayments and greater emphasis on negotiated
performance requirements. This trend has increased, and may continue to
increase, days sales outstanding in accounts receivable. This trend could have
an impact on the Company's ability to maintain its current level of working
capital. The number of days sales outstanding in accounts receivable was 109
days at March 31, 1998, compared to 117 days at December 31, 1997 and 86 days at
March 31, 1997. The number of days sales outstanding in accounts receivable net
of advance billings was 75 days at March 31, 1998 compared to 82 days at
December 31, 1997 and 61 days at March 31, 1997. The increase is primarily due
to the change in payment methodology discussed above as well as a reduction in
revenue resulting from the previously discussed contract cancellations.

The Company had cash and cash equivalents of $19.7 million at March 31, 1998 as
compared to $28.3 million at December 31, 1997 and $27.7 million at March 31,
1997.

During the three months ended March 31, 1998, net cash used by operating
activities totaled $6.5 million, primarily due to a loss before depreciation and
amortization of $0.5 million, an increase in accounts receivable of $2.3
million, an increase in net tax receivables of $1.5 million, a decrease in
accounts payables and accrued expenses of $2.6 million, and an increase in other
current assets of $2.3 million, which was partially offset by an increase in net
payables to investigators of $2.7 million.


                                       11

<PAGE>   14


Cash used in investing activities of $2.6 million during the first quarter of
1998 consisted of capital expenditures of $1.0 million and the purchase of an
option to acquire MPI, Inc. for $1.6 million. Capital expenditures have
primarily been made for computer system additions and upgrades, personal
computer equipment and expenditures on facility improvements. Capital
expenditures are estimated to be approximately $15.0 million in 1998, of which
approximately one-half relates to leasehold improvements to be paid when the
Company moves into its new clinical research center in Research Triangle Park,
North Carolina, improvements to be made to the Company's information technology
platform, and expansion of the Company's preclinical Canadian facility.

In the first quarter of 1998, the Company replaced its $10.0 million domestic
credit facility with a $15.0 million domestic credit facility which has
expansion capabilities to $40.0 million. Credit availability under the Company's
new domestic line of credit and its foreign line of credit (the "Credit
Facilities") totals approximately $18.5 million. There were no borrowings
outstanding under the lines of credit at March 31, 1998. Commitment availability
at March 31, 1998 has been reduced by issued letters of credit of approximately
$750,000. The lines are collateralized by certain of the Company's assets and
amounts outstanding would bear interest at a fluctuating rate based either on
the respective banks' prime interest rate or the London Interbank Offered Rate
("LIBOR"), as elected by the Company. Borrowings available under the lines of
credit are subject to certain financial and operating covenants. The Company's
Canadian subsidiary borrowed approximately $382,000 from the Canadian government
in March 1998. This borrowing bears no interest and is repayable in four annual
installments beginning in 1999.

The Company expects to continue expanding its operations through internal growth
and strategic acquisitions. The Company expects such activities will be funded
from existing cash and cash equivalents, cash flow from operations, and
available borrowings under its Credit Facilities. Although pressure on cash
reserves is expected, the Company estimates that its sources of cash will be
sufficient to fund the Company's current operations, including planned capital
expenditures, over the next year. There may be acquisition or other growth
opportunities which require additional external financing, and the Company may
from time to time seek to obtain additional funds from public or private
issuances of equity or debt securities. There can be no assurances that such
financings will be available on terms acceptable to the Company.

QUARTERLY RESULTS

The Company's quarterly operating results may fluctuate as a result of factors
such as delays experienced in implementing or completing particular clinical
trials and termination of clinical trials, the costs associated with integrating
acquired operations, foreign exchange fluctuations, as well as the costs
associated with opening new offices. Since a high percentage of the Company's
operating costs are relatively fixed while revenue is subject to fluctuation,
minor variations in the timing of contracts or the progress of clinical trials
(both delays and accelerations) may cause significant variations in quarterly
operating results. Results of one quarter are not necessarily indicative of
results for the next quarter.

YEAR 2000 COMPLIANCE

The Year 2000 Issue is the result of certain computer programs being written
using two digits rather than four digits to define the applicable year. This
software recognizes a date using "00" as the year 1900 rather than 2000


                                       12

<PAGE>   15


which could result in system failures, miscalculations, etc. Based upon a recent
assessment, the Company has determined certain software programs and computer
hardware will be modified or replaced as part of its on-going capital
expenditure program so that such programs are Year 2000 compliant. The cost
associated with these modifications and/or replacement is not expected to be
material to the Company. However, there can be no guarantee that the software of
outside vendors on which the Company's systems rely will be timely converted.

EXCHANGE RATE FLUCTUATIONS

The Company conducts business in several foreign countries and as a result
exposure exists to potentially adverse movement in foreign currency rates. The
Company uses foreign exchange contracts to hedge the risk of changes in foreign
currency exchange rates associated with contracts in which the expenses for
providing services are incurred in one currency and paid for by the client in
another currency. The objective of these contracts is to reduce the effect of
foreign exchange rate fluctuations on the Company's operating results.

INCOME TAXES

The Company's financial statements do not reflect U.S. or additional foreign
taxes on the possible distribution of undistributed earnings of foreign
subsidiaries as those earnings have been permanently reinvested. Should the
Company determine the need to distribute these undistributed earnings of foreign
subsidiaries, it would be subject to both U.S. income taxes (subject to an
adjustment for foreign tax credits) and withholding taxes payable to various
countries.

                           LOAN AND SECURITY AGREEMENT


         THIS AGREEMENT, made this 27th day of March, 1998, is by and among
NationsBank of Tennessee, N.A., a national banking association ("NationsBank",
and together with any other banks executing this Agreement, the "Banks"),

wholly-owned Subsidiaries of the Borrower listed in Exhibit A attached hereto
(the "Guarantors"), and NationsBank of Tennessee, N.A., as agent for the Banks
(the "Agent").

                                    RECITALS

         Borrower has requested that the Banks make a revolving line of credit
available to Borrower for general corporate purposes, including working capital,
the issuance of letters of credit and the funding of acquisitions of operating
companies within similar or complementary lines of business to that of the
Borrower. The Banks are willing to make such line of credit available to
Borrower on the terms and conditions set forth in this Agreement.

         "PRO-FORMA EFFECT" means, in making any calculation to determine if the
Borrower and its Subsidiaries and Foreign Subsidiaries are in compliance with
Subparagraph 6.15(b), to determine if the conditions precedent to a Permitted
Acquisition under Subparagraph 7.15(a) have been met, or to calculate the
Applicable LIBO Rate Margin or Applicable Floating Rate Margin, that the
calculation will be made assuming that (a) any Permitted Acquisition made during
the twelve-month period ending on the date of determination (the "Reference
Period"), and (b) any Indebtedness associated with (a) incurred during the
Reference Period or to be incurred as of the date of determination, were made or
incurred on the first day of the Reference Period. Any funds to be used by
Borrower or any Subsidiary or Foreign Subsidiary in consummating a Permitted
Acquisition will be assumed to have been used for that purpose as of the first
day of the Reference Period. EBITDA for the Reference Period associated with the
assets acquired or to be acquired in any Permitted Acquisition will be included
in the calculation of EBITDA for Borrower and its Subsidiaries and Foreign
Subsidiaries. Any Indebtedness to be incurred by Borrower or any Subsidiary or
Foreign Subsidiary in connection with the consummation of any Permitted
Acquisition will be assumed to have been incurred on the first day of the
Reference Period. Interest Expense with respect to such Indebtedness assumed to
have been incurred on the first day of the Reference Period which bears interest
at a floating rate shall be calculated at the current rate under the agreement
governing such Indebtedness (including this Agreement if the Indebtedness is
incurred hereunder). Any Interest Expense incurred during the Reference Period
which was or is to be refinanced with the proceeds of Indebtedness assumed to
have been incurred as of the first day of the Reference Period will be excluded
from the calculation for which a Pro-Forma Effect is being given.

account, and if any such instrument or chattel paper is received, the Borrower
or any Subsidiary will immediately notify Bank and, at the latter's request,

Foreign Subsidiary pledged hereunder, the Banks agree that, so long as no
Default exists hereunder, the consent of the Banks to such release shall not be

                              SECTION 2. THE LOANS.

         2.1      The Loan Commitments.

                  (a) Subject to the terms and conditions of and relying on the
representations, warranties and covenants contained in this Agreement, each Bank
agrees to fund severally but not jointly to the Borrower an aggregate maximum
principal amount of up to $40,000,000; provided, no more than $15,000,000.00
shall be initially committed and funded hereunder unless and until each of the
following occur:

                            (i) The Borrower elects to increase the Commitments 
by an additional amount up to $25,000,000.00 (the "Increase Amount") to a total
not to exceed $40,000,000.00 pursuant to a writing (the "Expansion Option");

                            (ii) Such Expansion Option is made by the Borrower 
and delivered to the Agent on or prior to the earlier to occur of (A) March 31,

below) and is accompanied by an additional commitment fee of 0.15% of the
Increase Amount;

                           (iii) No Event of Default or Unmatured Default is in 
existence hereunder.

Subject to the foregoing provisions for increases in the Commitments, each
advance of Loans made hereunder shall be made by each Bank ratably in accordance
with its respective Commitment Percentage of such advance. The Borrower may
obtain Loans, repay without penalty or premium except as set forth in Paragraph
2.10 below and reborrow hereunder, from the date of this Agreement up to the
date prior to the earlier to occur of (i) March 31, 2000, or (ii) the delivery

$100,000.00 and in an integral multiple of $100,000.00 if in excess thereof.

                  (b) The Credit Facility shall be evidenced initially by the  
$15,000,000.00 Note of Borrower payable to the order of NationsBank.

                  (c) Loans may be used by the Borrower for general corporate
purposes, including working capital, the issuance of Letters of Credit and the
funding of Permitted Acquisitions; provided, that the Banks shall have no
obligation to fund if the conditions precedent in Paragraph 3.2 below have not
been satisfied, including, without limitation, the requirement that the
Borrowing Base exceed the total amount outstanding under the Credit Facility
(including the face amount of any outstanding Letters of Credit) following any
such advance.

                  (d) The failure of any Bank to make any advances hereunder
pursuant to its Loan Commitment shall not relieve any other Bank of its
obligation, if any, hereunder to make its advances pursuant to its Loan
Commitment. However, no Bank shall be responsible for any other Bank's failure
or refusal to make any advances pursuant to such other Bank's Loan Commitment.



                                       16
<PAGE>   17


                  (e) If, at any time, the aggregate outstanding principal
balance of the Credit Facility (including the face amount of any outstanding
Letters of Credit) exceeds the Borrowing Base, a principal payment in the amount
of such excess shall be immediately due and payable. All outstanding principal
and interest on the Credit Facility shall be due and payable in full in a
balloon installment on March 31, 2000, unless and until each of the following
occur:

                           (i) The Borrower elects to term out the balance of 
the Credit Facility and extend the Loan Termination Date pursuant to a writing
(the "Extension Option") delivered to the Agent;

                            (ii) Such Extension Option is made by the Borrower 
and delivered to the Agent on or prior to March 1, 2000, and is accompanied by
an additional commitment fee equal to .30% of the then outstanding balance of
the Credit Facility;

                           (iii) No Event of Default or Unmatured Default is in 
existence hereunder.

If the Borrower satisfies each of the conditions set forth in clauses (i), (ii)
and (iii) above, the Loan Termination Date shall be extended to the eighth
Quarterly Date after the delivery of the Extension Option. In such event, the
then outstanding balance of the Credit Facility shall be termed out over two (2)
years, and no further advances shall be permitted under the Credit Facility. In
addition to interest due on each Interest Payment Date, quarterly principal
payments, each in the amount of 5% of the Total Commitments, shall be due and
payable on each Quarterly Date, beginning on the second Quarterly Date after the
delivery of the Extension Option.

         2.2      Borrowing Notices, Interest Rates and Payments of Interest.

                  (a) Loans made hereunder may be either Eurodollar Loans,
Floating Rate Loans, or a combination thereof; provided, Eurodollar Loans shall
be in the minimum amount of $100,000.00 and shall be in an integral multiple of
$100,000.00.

                  (b) The Borrower shall give the Agent irrevocable notice in
the form attached hereto as Exhibit 2.2(b)(i) (a "Borrowing Notice"),
accompanied by a completed and certified Borrowing Base Certificate in the form
attached hereto as Exhibit 2.2(b)(ii), not later than 10:00 a.m. Nashville time,
at least three (3) Business Days prior to the date of any requested disbursement
of Eurodollar Loans and one (1) Business Day prior to any requested disbursement
of Floating Rate Loans. Each Borrowing Notice shall be filled in and signed and
may be made by telecopier, telex or cable in addition to the means set forth for
giving notice in Paragraph 10.5. Each Borrowing Notice shall specify the
requested date of such requested disbursement; the aggregate amount of such
disbursement; the type of Loan, i.e., Eurodollar or Floating Rate; and if a
Eurodollar Loan, the designated Interest Period. The Agent shall promptly advise
the other Banks of any Borrowing Notice given pursuant to this Subparagraph and
each Bank's portion of the requested Loan. Not later than noon (12:00 p.m.)
Nashville time on each disbursement date, and subject to the terms and
conditions hereof, Agent will credit the proceeds of the Loans received by Agent
from the Banks to the Borrower's deposit account with Agent. Each such Borrowing
Notice shall obligate the Borrower to accept the Loan disbursement requested
thereby.



                                       17
<PAGE>   18


                  (c) The Borrower shall have the right at any time, on prior
irrevocable written or telex notice to the Agent not later than 10:00 a.m.,
Nashville time, three (3) Business Days prior to the date of any requested
conversion, to convert any Floating Rate or Eurodollar Loan into a Loan of
another type, or to continue any Eurodollar Loan for another Interest Period
(specifying in each case the Interest Period to be applicable thereto), subject
in each case to the following:

                           (i) Each conversion or continuation shall be made  
         prorata among the Banks in accordance with the respective principal 
         amounts of the Loan converted or continued;

                           (ii) No Eurodollar Loan shall be converted at any 
         time other than at the end of the Interest Period applicable thereto;

                           (iii) Each conversion shall be effected by applying
         the proceeds of the new Eurodollar and/or Floating Rate Loan, as the
         case may be, to the Loan (or portion thereof) being converted;

                           (iv) The number of Eurodollar Loans outstanding at 
         one time may not exceed six (6); and

                           (v) No Interest Period may be selected for any
         Eurodollar Loan that would end later than a repayment date occurring on
         or after the first day of such Interest Period if the aggregate
         outstanding amount of Eurodollar Loans with Interest Periods ending
         prior to such repayment date plus the aggregate outstanding amount of
         all Floating Rate Loans is not equal to or greater than the principal
         amount(s) of the Loan(s) to be paid on such repayment date.

                  (d) Each notice pursuant to this Paragraph shall be
irrevocable and shall refer to this Agreement and specify (1) the identity and
principal amount of the particular Loan that the Borrower requests be converted
or continued, (2) if such notice requests conversion, the date of such
conversion (which shall be a Business Day), and (3) if a Loan is to be converted
to a Eurodollar Loan or a Eurodollar Loan is to be continued, the Interest
Period with respect thereto. In the event that the Borrower shall not give
notice to continue any Eurodollar Loan for a subsequent period, such Eurodollar
Loan (unless repaid) shall automatically be converted into a Floating Rate Loan.
If the Borrower shall fail to specify in any Borrowing Notice the type of
borrowing or, in the case of a Eurodollar Loan, the applicable Interest Period,
the Borrower will be deemed to have requested a Floating Rate Loan. If Agent
reasonably believes that any failure by Borrower to specify the type of
borrowing or the applicable Interest Period shall have resulted from failure of
communications equipment or clerical error, then prior to funding any such
borrowing the Agent shall use reasonable efforts to obtain confirmation from
Borrower of the contents of such Borrowing Notice; however, in the absence of
prompt confirmation by Borrower which specifies the type of borrowing and/or the
applicable Interest Period, the Borrower will be deemed to have requested a
Floating Rate Loan. Notwithstanding anything to the contrary contained above, if
an Event of Default shall have occurred and be continuing, no Eurodollar Loan
may be continued and no Floating Rate Loan may be converted into a Eurodollar
Loan.


                                       18

<PAGE>   19

                  (e) Interest shall be charged and paid on each Loan from the
date of the initial advance thereunder until such Loan is paid or converted as
follows:

                           (i) For a Floating Rate Loan, at an annual rate equal
         to the Prime Rate plus the Applicable Prime Rate Margin, said rate to
         change contemporaneously with any change in the Prime Rate;

                           (ii) For a Eurodollar Loan, at a rate equal to the 
         LIBO Rate plus the Applicable LIBO Rate Margin;

                           (iii) The Borrower shall pay to any Bank, if and so
         long as such Bank shall be required under regulations of the Board of
         Governors of the Federal Reserve System to maintain reserves with
         respect to liabilities or assets consisting of or including Eurodollar
         Liabilities, additional interest on the unpaid principal amount of each
         Eurodollar Loan, from the date of such advance until said principal
         amount is paid in full, at an interest rate per annum equal at all
         times to the remainder obtained by subtracting (i) the LIBO Rate for
         the Interest Period from (ii) the rate obtained by dividing the LIBO
         Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve
         Percentage for such Interest Period, payable on each date on which
         interest is payable. Such additional interest shall be determined by
         such Bank who shall notify Borrower thereof.

                           (iv) Interest for both Floating Rate Loans and 
Eurodollar Loans shall be computed on the basis of a 360-day year counting the
actual number of days elapsed, and shall be due and payable without notice on
each Interest Payment Date.

                  (f) Notwithstanding the foregoing, upon the occurrence of an
Event of Default interest may be charged at the Default Rate as defined and set
forth in the Notes if the Majority Banks so elect, regardless of whether the
Majority Banks have elected to exercise any other remedies under Section 8
hereof, including, without limitation, acceleration of the maturity of the
outstanding principal of the Notes. All such interest shall be paid at the time
of and as a condition precedent to the curing of any such default to the extent
any right to cure is given.

                  (g) All agreements herein made are expressly limited so that
in no event whatsoever shall the interest and loan charges agreed to be paid to
the Banks for the use of the money advanced or to be advanced pursuant to this
Agreement exceed the maximum amounts collectible under applicable laws in effect
from time to time. If for any reason whatsoever the interest or loan charges
paid or contracted to be paid in respect of the Loans shall exceed the maximum
amounts collectible under applicable laws in effect from time to time, then,
ipso facto, the obligation to pay such interest and/or loan charges shall be
reduced to the maximum amounts collectible under applicable laws in effect from
time to time, and any amounts collected by the Banks that exceed such maximum
amounts shall be applied to the reduction of the principal balance of the Loans
and/or refunded to Borrower so that at no time shall the interest or loan
charges paid or payable in respect of the Loans exceed the maximum amounts
permitted from time to time by applicable law. This provision shall control
every other provision herein and in any and all other agreements and instruments
now existing or hereafter arising between Borrower and the Banks with respect to
the Loans.

         2.3 Letters of Credit. Subject to the terms and conditions of this
Agreement, the Commitments may be utilized, upon the request of the Borrower, in
addition to the Loans provided for by Paragraph 2.1, for the issuance by the
Issuing Bank of letters of credit (collectively, the "Letters of Credit") for
the account of the Borrower; provided that in no event shall (i) the aggregate
amount of all Letter of Credit Liabilities, together with the aggregate
principal amount of the Loans exceed the aggregate amount of the Total
Commitments as in effect from time to time, and (ii) the expiration date of any
Letter of Credit extend beyond the earlier of March 31, 2000, and the date
twelve months following the issuance of such Letter of Credit. The following
additional provisions shall apply to Letters of Credit:

                  (a) The Borrower shall give the Agent at least three Business
Days' irrevocable prior notice (effective upon receipt) specifying the Business
Day (which shall be no later than 30 days preceding the Loan Termination Date)
each Letter of Credit is to be issued and describing in reasonable detail the
proposed terms of such Letter of Credit (including its beneficiary) and the
nature of the transactions or obligations proposed to be supported. The Borrower
shall be the account party for each Letter of Credit, including Letters of
Credit issuable to a beneficiary having a claim or potential claim against a
Subsidiary of the Borrower.

                  (b) On each day during the period commencing with the issuance
by the Issuing bank of any Letter of Credit and until such Letter of Credit
shall have expired or been terminated or, if drawn upon, until the resulting
Reimbursement Obligations have been reimbursed in full by the Borrower (whether
by a borrowing under this Agreement or otherwise), the Commitment of each Bank
shall be deemed to be utilized for all purposes of this Agreement in an amount
equal to such Bank's Commitment Percentage of the then Letter of Credit
Liabilities associated with such Letter of Credit. Each Bank (other than the
Issuing Bank) agrees that, upon the issuance of any Letter of Credit it shall
automatically acquire a participation in the Issuing Bank's liability under such
Letter of Credit in an amount equal to such Bank's Commitment Percentage of such
liability, and each Bank (other than the Issuing Bank) thereby shall absolutely,
unconditionally and irrevocably assume, as primary obligor and not as surety,
and shall be unconditionally obligated to the Issuing Bank to pay and discharge
when due, its Commitment Percentage of the Issuing Bank's liability under such
Letter of Credit.

                  (c) Upon receipt from the beneficiary of any Letter of Credit
or any demand for payment under such Letter of Credit, the Issuing Bank shall
promptly notify the Borrower (through the Agent) of the amount to be paid by the
Issuing Bank as a result of such demand and the date on which payment is to be
made by the Issuing Bank to such beneficiary in respect of such demand. The
Borrower hereby unconditionally agrees to pay and reimburse the Agent for the
account of the Issuing Bank and other Banks with respect to their Letter of
Credit Interest for the amount of each demand for payment under such Letter of
Credit at or prior to the date on which payment is to be made by the Issuing
Bank to the beneficiary under such Letter of Credit, without presentment,
demand, protest or other formalities of any kind. Any amounts not so paid or
borrowed as set forth in Subparagraph 2.3(d) below shall bear interest at the
rate(s) specified in the Letter of Credit Documents or, if higher, at the
rate(s) specified on the Notes (including the Default Rate, if applicable).



                                       20

<PAGE>   21


                  (d) Forthwith upon its receipt of a notice referred to in
clause Subparagraph 2.3(c), the Borrower shall advise the Agent whether or not
the Borrower intends to borrow under Paragraph 2.1 to finance its obligation to
reimburse the Issuing Bank for the amount of the related demand for payment and,
if it does, submit a notice of such borrowing as provided in Paragraph 2.2. In
the event that the Borrower fails to so advise the Agent, and if the Borrower
fails to reimburse the Issuing Bank for a demand for payment under a Letter of
Credit by the date of such payment, the Agent shall give each Bank prompt notice
of the amount of the demand for payment, specifying such Bank's Commitment
Percentage of the amount of the related demand for payment, and the Borrower
shall be deemed in default hereunder for breaching Subparagraph 2.3(c) above.

                  (e) Each Bank (other than the Issuing Bank) shall pay to the
Agent for the account of the Issuing Bank in Dollars and in immediately
available funds, the amount of such Bank's Commitment Percentage of any payment
under a Letter of Credit upon notice by the Agent to such Bank requesting such
payment and specifying such amount as provided in clause (d) of the Paragraph
2.3. Each such Bank's obligation to make such payments to the Agent for the
account of the Issuing Bank under this clause (e), and the Issuing Bank's right
to receive the same, shall be absolute and unconditional and shall not be
affected by any circumstance whatsoever, including (i) the failure of any other
Bank to make its payment under this clause (e), the financial condition of the
Borrower (or any other account party), the existence of any Default or (ii) the
termination of the Commitments. Each such payment to the Issuing Bank shall be
made without any offset, abatement, withholding or reduction whatsoever;
provided, nothing contained in the foregoing shall limit the Issuing Bank's
liability for its gross negligence or willful misconduct in improperly honoring
a draft drawn under a Letter of Credit.

                  (f) Upon the making of each payment by a Bank to the Issuing
Bank pursuant to clause (e) above in respect of any Letter of Credit, such Bank
shall, automatically and without any further action on the part of the Agent,
the Issuing Bank or such Bank, acquire (i) a participation in any amount equal
to such payment in the Reimbursement Obligation owing to the Issuing Bank by the
Borrower under this Agreement and under the Letter of Credit Documents relating
to such Letter of Credit and (ii) a participation in a percentage equal to such
Bank's Commitment Percentage in any interest or other amounts payable by the
Borrower under such Letter of Credit Documents and the other Loan Documents in
respect of such Reimbursement Obligation (other than the commissions, charges,
costs and expenses payable to the Issuing Bank pursuant to clause (g) of this
Paragraph 2.3). Upon receipt by the Issuing Bank from or for the account of the
Borrower of any payment in respect of any Reimbursement Obligation or any such
interest or other amount (including by way of set-off or application of proceeds
of any collateral security) the Issuing Bank shall promptly pay to the Agent for
the account of each Bank who shall have previously assumed a participation in
such payment under clause (ii) above, such Bank's Commitment Percentage of such
payment, each such payment by the Issuing Bank to be made in the same money and
funds in which received by the Issuing Bank. In the event any payment received
bye the Issuing Bank and so paid t the Banks is rescinded or must otherwise be
returned by the Issuing Bank, each Bank shall, upon request of the Issuing Bank
(through the Agent), repay to the Issuing Bank (through the Agent) the amount of
such payment paid to such Bank, with interest at the rate specified in clause
(j) of this Paragraph 2.3.

                  (g) Borrower shall pay the Agent for the account of each Bank
a letter of credit fee in respect of each Letter of Credit on the daily average
undrawn face amount of such Letter of 



                                       21

<PAGE>   22

Credit for the period from and including the date of issuance of such Letter of
Credit to and including the date such Letter of Credit is drawn in full, expires
or is terminated (such fee to be non-refundable, to be paid in arrears on each
Quarterly Date and on the Loan Termination Date and to be calculated, for any
day, after giving effect to any payments made under such Letter of Credit on
such day) in an amount equal to the Applicable LIBOR Rate Margin per annum. All
calculations of Letter of Credit fees shall be based on a 360 day year counting
the actual number of elapsed days.

                  (h) Upon the request of any Bank from time to time, the
Issuing Bank shall deliver any information reasonably requested by such Bank
with respect to each Letter of Credit then outstanding.

                  (i) The issuance by the Issuing Bank of each Letter of Credit
shall be subject, in addition to the conditions precedent set forth in Paragraph
3.2, to the conditions precedent that (i) such Letter of Credit shall be in such
form, contain such terms and support such transactions as shall be satisfactory
to the Issuing Bank consistent with its then current practices as shall be
satisfactory to the Issuing Bank consistent with its then current practices and
procedures with respect to letters of credit of the same type and (ii) the
Borrower shall have executed and delivered such applications, agreements and
other instruments relating to such Letter of Credit as the Issuing Bank shall
have reasonably requested consistent with its then current practices and
procedures with respect to letters of credit of the same type; provided that in
the event of any conflict between any such application, agreement or other
instrument and the provisions of this Agreement, the provisions of this
Agreement shall control.

                  (j) In the event that any Bank fails to pay any amount
required to be paid pursuant to clause (e) or (f) of this Paragraph 2.3 when
due, such Bank shall pay interest to the Issuing Bank (through the Agent) on
such amount from and including such due date to but excluding the date such
payment is made (i) during the period from and including such due date to but
excluding the date three Business Days thereafter, at a rate per annum equal to
the Federal Funds Rate (as in effect from time to time) and (ii) thereafter, at
a rate per annum equal to the Prime Rate plus 2.0%.

                  (k) The issuance by the Issuing Bank of any modification or
supplement to any Letter of Credit shall be subject to the same conditions
applicable under this Paragraph 2.3 to the issuance of new Letters of Credit,
and no such modification or supplement shall be issued unless either (x) the
respective Letter of Credit as affected by such action would have complied with
such conditions had it originally been issued in such modified or supplemented
form or (y) each Bank shall have consented to such modification or supplement.

                  (l) The obligations of the Borrower under this Paragraph 2.3
shall be unconditional and absolute and shall not be affected, modified or
impaired, upon the happening at any time or from time to time of any event,
including any of the following, whether or not with notice to or the consent of
the Borrower:

                           (i) the compromise, settlement, release,
         modification, amendment (whether material or otherwise) or termination
         of any or all of the obligations, conditions covenants or agreements of
         any Person in respect of any of the Loan Documents:

<PAGE>   23


                           (ii) the occurrence, or the failure by the Agent, any
         Bank or any other Person to give notice to the Borrower of the
         occurrence, of any Event of Default or any default under any of the
         other Loan Documents;

                           (iii) the waiver of the payment, performance or  
         observance of any of the obligations, conditions, covenants or 
         agreements of any Person contained in any of the Loan Documents;

                           (iv) the extension of the time for performance of any
         other obligations, covenants or agreements of any Person under or 
         arising out of any of the Loan Documents;

                           (v) the taking or the omission of any of the actions 
         referred to in any of the Loan Documents;

                           (vi) any failure, omission or delay on the part of
         the Agent, any Bank, the Borrower or the beneficiary of any Letter of
         Credit to enforce, assert or exercise any right, remedy, power or
         privilege conferred by this Agreement or any of the Loan Documents, or
         any other act or acts on the part of the Agent, any Bank, the Borrower
         or the beneficiary of any Letter of Credit;

                           (vii) the voluntary or involuntary liquidation,
         dissolution, sale or other disposition of all or substantially all the
         assets of, the marshaling of assets and liabilities, receivership,
         insolvency, bankruptcy, assignment for the benefit of creditors,
         reorganization, arrangement, composition with creditors or readjustment
         of, or other similar proceedings which affect, the Borrower or any
         other party to any of the Loan Documents;

                           (viii) any lack of validity or enforceability of this
         Agreement, any Letter of Credit or any other Loan Document, or any
         allegation of invalidity or unenforceability or any contest of such
         validity or enforceability;

                           (ix) the existence of any claim, set-off, defense or
         other right which the Borrower may have at any time against the Agent,
         any Bank or any beneficiary or any transferee of any Letter of Credit
         (or any persons or entities for whom the Bank or any such beneficiary
         of transferee may be acting), or any other Person, whether in
         connection with this Agreement or any other Loan Document or any of the
         transactions contemplated by any Loan Document or any unrelated
         transaction;

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

                           (xi) payment by the Issuing Bank under any Letter of
         Credit against presentation of a demand or certificate which does not
         comply with the terms of such Letter of Credit;



                                       23
<PAGE>   24

                           (xii) the release or discharge by operation of law of
         the Borrower from the performance or observance of any obligation,
         covenant or agreement contained in any of the Loan Documents; or

                           (xiii) any circumstance or happening whatsoever,  
         whether or not similar to any of the foregoing.

                  (m) Without affecting the Borrower's liability under Paragraph
10.7, the Borrower agrees to indemnify each of the Issuing Bank, the Agent and
the Banks and their respective affiliates, directors, officers, employees,
attorneys and agent from, and hold each of them harmless against, any and all
losses, liabilities, damages or expenses incurred by any of them in connection
with or by reason of any actual or threatened investigation, litigation or other
proceeding (including, in respect of the Issuing Bank and the Agent, any such
Bank) relating to (a) the execution and delivery of any Letter of Credit; (b)
the use of the proceeds of any drawing under any Letter of Credit; or (c) the
transfer or substitution of, or payment or failure to pay under, any Letter of
Credit, including the reasonable fees and disbursements of counsel incurred in
connection with any such investigation, litigation or other proceeding, but
excluding damages, losses, liabilities or expenses to the extent, but only to
the extent, incurred by reason of (x) the willful misconduct or gross negligence
of the Issuing Bank in determining whether a document presented under any Letter
of Credit complies with the terms of such Letter of Credit or (y) in the case of
the Issuing Bank, such Bank's failure to pay under any such Letter of Credit
after presentation to it of documents strictly complying with the terms and
condition of such Letter of Credit. It shall not be a condition to any such
indemnification that the Issuing Bank, the Agent or any Bank shall be a party to
any such investigations, litigation or other proceeding. Nothing in this
Paragraph 2.3 is intended to limit the Borrower's payment obligations under this
Agreement.

                  (n) The Borrower assumes all risks of the acts or omissions of
any beneficiary of any Letter of Credit with respect to the use of the Letter of
Credit. None of the Agent, any Bank nor any of their respective affiliates,
officers, directors, employees, attorneys or agents shall be liable or
responsible for: (a) the use which may be made of the Letter of Credit or for
any acts or omissions of any beneficiary of any Letter of Credit in connection
with such Letter of Credit; (b) the validity, sufficiency or genuineness of
documents presented to the Issuing Bank, or of any endorsement on such
documents, even if such documents should in fact prove to be in any or all
respects invalid, insufficient, fraudulent or forged; (c) payment by the Issuing
Bank against presentation of documents which do not comply with the terms of any
Letter of Credit, including failure of any documents to bear any reference or
adequate reference to such Letter of Credit; or (d) any other circumstances
whatsoever in making or failure to make payment under any Letter of Credit;
provided however, that Subparagraph 2.3(l) above notwithstanding, the Borrower
shall have a claim against the Issuing Bank to the extent, but only to the
extent, of any direct, as opposed to consequential, damages suffered by the
Borrower which the Borrower proves were caused by (i) the Issuing Bank's willful
misconduct or gross negligence in determining whether a document presented under
any Letter of Credit complies with the terms of such Letter of Credit or (ii)
the Issuing Bank's willful failure to pay under the Letter of Credit after
presentation to it of documents strictly complying with the terms and conditions
of such Letter of Credit. In furtherance and not in limitation of the foregoing,
the Issuing bank may accept documents that appear on their face to be in order,
without responsibility for further investigation.

         2.4 Arrangement Fee. An aggregate nonrefundable Arrangement Fee of  
$22,500 shall be due and payable in full at Closing to the Agent.

         2.5 Commitment Fee. An aggregate commitment fee equal to the product of
(i) 0.15% per annum multiplied by (ii) then current Total Commitments, without
regard to the Borrowing Base, less the average outstanding daily balance of the
Credit Facility (including the face amount of any letters of credit then
outstanding) during the immediately preceding quarter shall be due and payable
quarterly in arrears.

         2.6 Agent's Fee. An agent's fee of $5,000 per annum for each Bank other
than NationsBank that is a party to this Agreement shall be due and payable by
Borrower to the Agent annually commencing with the date of the admission of the
Bank hereto other than NationsBank and an each anniversary thereof.

          2.7     Alternate Rate of Interest.

                  a. In the event, and on such occasion, that on the date of
commencement of any Interest Period for a Eurodollar Loan, any Bank shall have
reasonably determined:

                        (i) That dollar deposits in the amount of the requested 
principal amount of such Eurodollar Loan are not generally available to
first-class banks in the London Interbank Market;

                        (ii) That the rate at which such dollar deposits are  
being offered will not adequately and fairly reflect the cost to Bank of making
or maintaining such Eurodollar Loan during such Interest Period; or

                        (iii) That reasonable means do not exist for 
ascertaining the LIBO Rate generally,

such Bank shall, as soon as practicable thereafter, give written or telephonic
notice of such determination to the Agent and the Borrower. In the event of any
such determination, any request by the Borrowers for a Eurodollar Loan pursuant
to Section 2.2 shall, until the circumstances giving rise to such notice no
longer exist, be deemed to be a request for a Floating Rate Loan. Each
determination by such Bank hereunder shall be conclusive absent manifest error.

          2.8     Change in Circumstances.

                  a. Notwithstanding any other provision herein, if after the
date of this Agreement any change in applicable Laws or regulations or in the
interpretation or administration thereof by any governmental authority charged
with the interpretation or administration thereof (whether or not having the
force of law) shall change the basis of taxation of payments to a Bank under any
Eurodollar Loan made by Bank or any other fees or amounts payable hereunder
(other than taxes imposed on the overall net income of a Bank by the country in
which such Bank is located, or by the jurisdiction in which such Bank has its
principal office, or by any political subdivision or taxing authority therein),
or shall impose, modify, or deem applicable any reserve requirement, special
deposit, insurance charge 



                                       25

<PAGE>   26

(including FDIC insurance on Eurodollar deposits) or similar requirements
against assets of, deposits with or for the account of, or credit extended by,
such Bank or shall impose on such Bank or the London Interbank Market any other
condition affecting this Agreement or Eurodollar Loans made by such Bank, and
the result of any of the foregoing shall be to increase the cost to such Bank of
making or maintaining its Eurodollar Loan or to reduce the amount of any sum
received or receivable by such Bank for any of its Eurodollar Loans hereunder
(whether of principal, interest or otherwise) by an amount reasonably deemed by
such Bank to be material, then the Borrowers will pay to such Bank such
additional amount or amounts as will reasonably compensate Bank for such
additional costs.

                  b.    If either:

                        (i) The introduction of, or any change in, or in the  
interpretation of, any United States or foreign law, rule or regulation; or

                        (ii) Compliance with any directive, guidelines or 
request from any central bank or other United States or foreign governmental
authority (whether or not having the force of law) promulgated or made after the
date hereof (but excluding, however, any law, rule, regulation, interpretation,
directive, guideline or request contemplated by or resulting from the report
dated July, 1988, entitled "International Convergence of Capital Measurement and
Capital Standards" issued by the Basic Committee on Banking Regulations and
Supervisory Practices), affects or would affect the amount of capital required
or expected to be maintained by such Bank (or any lending office of such Bank)
or any corporation directly or indirectly owning or controlling such Bank (or
any lending office of such Bank) based upon the existence of this Agreement, and
such Bank shall have determined that such introduction, change or compliance has
or would have the effect of reducing the rate of return on such Bank's capital
or on the capital of such owning or controlling corporation as a consequence of
its obligations hereunder (including its Commitment) to a level below that which
such Bank or such owning or controlling corporation could have achieved but for
such introduction, change or compliance (after taking into account that Bank's
policies or the policies of such owning or controlling corporation, as the case
may be, regarding capital adequacy) by an amount deemed by such Bank (in its
sole discretion) to be material, then the Borrowers will pay to such Bank such
additional amount or amounts as will compensate such Bank for such reduction
attributable to making, funding and maintaining its Commitment, Loans and
Letters of Credit hereunder.

                  c. A certificate of a Bank setting forth such amount or
amounts as shall be necessary to compensate such Bank (or its participating
banks or other entities pursuant to this Agreement), as specified in Paragraph
(a) or (b) above, as the case may be, shall be delivered to Borrower and shall
be conclusive absent manifest error; provided, however, that the Borrower shall
be responsible for compliance herewith and the payment of increased costs only
to the extent:

                        (i) Any change in applicable Laws giving rise to  
increased costs occurs after the date of this Agreement; and

                        (ii) Such change in Laws or the application thereof 
applies generally to the banking industry and is not the result of one or more
of the Banks having inadequate or substandard capital as determined by its
regulators; and



                                       26

<PAGE>   27


                        (iii) The affected Bank gives notice of the change  
giving rise to increased costs within one hundred eighty (180) Business Days
after the date on which such Bank has, or with reasonable diligence should have
had, knowledge of the change, or else such Bank can only collect costs from and
after the date of the notice.

Subject to the foregoing, the Borrower shall pay the affected Bank the amount
shown as due on any such certificate within ten (10) days after its receipt of
such certificate.

                  d. The protection of this Section 2.8 shall be available to
Bank regardless of any possible contention of invalidity or inapplicability of
the law, regulation or condition that shall have been imposed.

          2.9     Change in Legality.

                  a. Notwithstanding anything to the contrary herein contained,
if any change in any law or regulation or in interpretation thereof by any
governmental authority charged with the administration or interpretation thereof
shall make it unlawful for any Bank to make or maintain any Eurodollar Loan or
to give effect to its obligations to make Eurodollar Loans as contemplated
hereby, then, by written notice to the Agent and the Borrower, such Bank may:

                        (i) Declare that Eurodollar Loans will not thereafter be
made by such Bank hereunder, whereupon the Borrowers shall be prohibited from
requesting Eurodollar Loans from such Bank hereunder unless such declaration is
subsequently withdrawn; and

                        (ii) Require that all outstanding Eurodollar Loans made 
by it be converted to Floating Rate Loans, in which event (A) all such
Eurodollar Loans shall be automatically converted to Floating Rate Loans as of
the effective date of such notice as provided in Paragraph(b) below, and (B) all
payments and prepayments of principal that would otherwise have been applied to
repay the converted Eurodollar Loans shall instead be applied to repay the
Floating Rate Loans resulting from the conversion of such Eurodollar Loans.

                  b. For purposes of this Section 2.9, a notice to Borrower and
Agent by any Bank, pursuant to (a) above, shall be effective, if lawful, on the
last day of the then current Interest Periods; in all other cases, such notice
shall be effective on the date of receipt by the Borrower.

         2.10     Optional Prepayment - Premiums in Certain Events.

                  (a) The Borrower may, upon three (3) Business Day's prior
written notice to the Agent, and upon payment of all premiums set forth in
Subparagraph (d) below, prepay any outstanding Eurodollar Loans prior to any
Interest Payment Date for such Eurodollar Loans, in whole or in part.

                  (b) The Borrower may at any time prepay any outstanding
Floating Rate Loans in whole or in part without premium or penalty.


                                       27

<PAGE>   28

                  (c) Each notice of prepayment of any Eurodollar Loan shall
specify the date and amount of such prepayment and shall be irrevocable. The
Agent shall promptly notify the Banks of its receipt of a notice of prepayment.
Each partial prepayment of any Eurodollar Loans shall be in an aggregate
principal amount which is the lesser of (1) the then outstanding principal
balance of the one or more Eurodollar Loans to be prepaid, or (2) $100,000.00 or
an integral multiple thereof. Interest on the amount prepaid accrued to the
prepayment date shall be paid on such date.

                  (d) Upon prepayment of any Eurodollar Loan on a date other
than the relevant Interest Payment Date for such borrowing, Borrower shall pay
to Agent for the account of each Bank, in addition to all other payments then
due and owing the Banks, premiums which shall be equal to an amount, if any,
reasonably determined by each Bank to be the difference between the rate of
interest then applicable to the relevant Eurodollar Loan and the yield each Bank
receives upon reinvestment of so much of the relevant Eurodollar Loans as is
prepaid for the remainder of the term of the relevant Eurodollar Loan or Loans.
Anything in this Section 2.10(d) to the contrary notwithstanding, the premiums
payable upon any such prepayment shall not exceed the amount, if any, reasonably
determined by each Bank to be the difference between the rate of interest then
applicable to the relevant Eurodollar Loan and the yield that each Bank could
receive upon reinvestment in the "Floor Reinvestment" of so much of the relevant
Eurodollar Loan as is prepaid for the remainder of the term of the relevant
Eurodollar Loan. For purposes hereof, "Floor Reinvestment" shall mean an
investment for the time period from the date of such prepayment to the end of
the relevant Interest Period applicable to such Eurodollar Loan at an interest
rate per annum equal to the Federal Fund Rate "offered" as published in the Wall
Street Journal on the date of such prepayment. All determinations, estimates,
assumptions, allocations and the like required for the determination of such
premiums shall be made by each Bank in good faith and shall be presumed correct
absent demonstrable error.

         2.11     Prepayment to the Agent.

                  (a) The Agent shall send the Borrower statements of all
amounts due hereunder (or the Banks may in the case of Section 2.7 above), which
statements shall be considered correct and conclusively binding on the Borrower
unless the Borrower notifies the Agent to the contrary within one hundred eighty
(180) days of its receipt of any statement to which it objects. All sums payable
to the Banks hereunder shall be paid directly to the Agent for the account of
each Bank in immediately available funds prior to 12:00 noon, Nashville time, on
the date when such sums are due and payable. Any amounts received by the Agent
after 12:00 noon Nashville time on any Business Day shall be deemed to have been
received on the next Business Day. Alternatively, at its sole discretion, the
Agent may charge against any deposit account of the Borrower maintained with any
of the Banks all or any part of any amount due pursuant to this Agreement.

                  (b) Each payment made to the Agent on the notes or for other
sums or fees due hereunder for the account of the Banks shall in like funds be
properly remitted by the Agent to each Bank, no later than 2:00 p.m. Nashville
time on the date on which Agent receives such payment.

                  (i) Join with the Agent in executing such additional  
Financing Statements (including amendments thereto and continuation statements
thereof) in form satisfactory to the Banks as the Banks may specify;

                  (ii) pay or reimburse the Agent and/or the Banks for all costs

Agreement shall be sufficient as a financing statement and may be filed in any
appropriate office in lieu thereof.

              (c) To the extent lawful, the Borrower hereby appoints the
Agent as its attorney-in-fact (without requiring the Agent to act as such) to

security interest in, and to protect and preserve, the Collateral.

         4.6 Collection of Notes and Receivables. Following the occurrence of
any Event of Default and for so long as such Event of Default remains uncured,
upon demand of the Majority Banks, Borrower and each of the Subsidiaries shall
deposit or cause to be deposited, all checks, drafts, cash, and other
remittances received in payment of services rendered or in payment or on account
of its accounts and notes receivable, immediately upon receipt thereof with
Agent in a special "lockboxed" bank account maintained with Agent, over which
the Agent alone shall have power or withdrawal. The funds in said special bank
account shall be held by the Agent on behalf of the Banks as security for all
loans made hereunder and all other Obligations to the Banks secured hereby. Said
proceeds shall be deposited in precisely the form received, except for the
endorsement of Borrower where necessary to permit collection, which endorsement
Borrower and each of the Subsidiaries agree to make and which Agent also hereby
is irrevocably authorized to make on its behalf. Pending such deposit, Borrower
agrees that it will not commingle any such checks, drafts, cash and other
remittances with any of its funds or property, but will hold them separate and
apart therefrom and upon an express trust for the Banks until deposit thereof is
made in the said special bank account. On a daily basis, Agent will apply the
whole or any part, as the Majority Banks deem appropriate, of the collected
funds on deposit in the said special bank account against the principal and/or
interest of any loans made hereunder and/or on Borrower's other Obligation's
secured hereby, the order and method of such application to be in the discretion
of the Majority Banks. Any portion of said funds on deposit in the special bank
account that the Majority Banks elect not to apply will be paid over by Agent to
Borrower.

covenants with the Agent for the benefit of the Banks, neither Borrower nor any
Subsidiary will (i) pledge, assign, encumber, or hypothecate the outstanding
stock or other ownership interest of any Foreign

grace periods) all Indebtedness for borrowed money (whether direct or indirect,
including Guarantee Obligations) due any Person, except when the amount thereof
is being contested in good faith by appropriate proceedings and with adequate
security therefor being set aside in a manner satisfactory to the Banks. If
default is made by the Borrower or any Subsidiary in the payment of any
principal (or installment thereof) of, or interest on, any such Indebtedness,
the Banks shall have the right, in their discretion, to pay such interest or
principal for the account of the Borrower or such Subsidiary and be reimbursed
by the Borrower therefor.

         6.10 Notice of Litigation. The Borrower will give immediate notice to
the Agent and provide copies to the Agent of: (1) any litigation or proceeding
in which the Borrower or any Subsidiary or Foreign Subsidiaries is a party if an
adverse decision therein would require them to pay over more than $1,000,000.00
or deliver assets the value of which exceeds such sum (if such claim is not
considered to be covered by insurance) or pay over more than $2,500,000.00 (if
such claim is considered to be covered by insurance); and (2) the institution of
any other suit or proceeding involving any of them, or the overt threat thereof,

         6.13 Environmental Compliance. In the event that the Banks have reason
to believe that the Borrower or any Subsidiary has failed to comply with any
material Environmental Laws, or there exists a threat of material harm to the
environment or Persons, the Banks of their agents shall have the right, but no
obligation, at any time during business hours and upon reasonable written
notice, to enter upon any property operated by a Borrower or Subsidiary and
conduct or cause to be conducted an Environmental Phase I audit (or an update of
any audit completed in connection with the execution of this Agreement) at
Borrower's sole expense and if such Phase I audit (or update) recommends further
testing, then the Banks or their agents may require, but shall not be obligated
to require, upon reasonable written notice, such further testing at Borrower's
sole expense. The Banks or their agents shall use their best efforts to invoke
and maintain all applicable privileges over all audit information generated
pursuant to this provision.

neutralization of any environmental activity;

then it shall provide the Agent and each Bank with a copy of such notice within
ten (10) Business Days of the Borrower's or such Subsidiary's receipt thereof.
Subject to the right of the Borrower or any Subsidiary to contest in good faith

promptly as possible resolve, cure and/or have dismissed with prejudice any such
actions or proceedings, to the reasonable satisfaction of the Banks. The

<PAGE>   44


(including, without limitation, the purchase, sale, lease or exchange of any
property or the rendering of any service) with any Affiliate (other than any
Subsidiary of Borrower) on terms that are less favorable to the Borrower or its
Subsidiaries than those that would be obtainable at the time from any Person who
is not an Affiliate.

         7.14 ERISA Compliance. The Borrower will not, and will not allow any of
its Subsidiaries or Foreign Subsidiaries to establish or set up any Defined

cause to be cured such failure, with such thirty (30) day period commencing
after notice of such failure from the Agent or Banks.

applicable grace period in any other Indebtedness (excluding the Obligations)

<PAGE>   46


         8.2 Acceleration. Upon the occurrence of any of such Events of Default,
the Majority Banks may, at their option, immediately terminate the obligation to
make any further advances and/or declare the principal and interest accrued on
the Notes and all other Obligations to be immediately due and payable, whereupon
the same shall become forthwith due and payable, without presentment, demand,
protest, or any notice of any kind except as set forth above; provided, that in
the case of the Events of Default specified in clause (g), (h) or (i) above with
respect to Borrower, without any notice to Borrower or any act by Agent or the
Banks, the Commitments shall thereupon terminate and the Notes and all other
Obligations shall become immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are waived by the
Borrower. In addition, and regardless of whether the Notes have been
accelerated, the Majority Banks may upon the occurrence of any Event of Default
elect to charge interest at the Default Rate set forth in the Notes.

         8.3 Remedies. After any acceleration, as provided for in Paragraph 8.2,
the Agent and/or Banks shall have, in addition to the rights and remedies given
it by the Loan Documents, all those allowed by all applicable Laws, including,
but without limitation, the UCC as enacted in any jurisdiction in which any
Collateral may be located. Without limiting the generality of the foregoing, the
Agent may immediately, without demand of performance and without other notice
(except as specifically required by the Loan Documents) or demand whatsoever to
the Borrower, all of which are hereby expressly waived, and without
advertisement, sell at public or private sale, in any manner and at any location
authorized by Laws, or otherwise realize upon, the whole, or, from time to time,
any part of the Collateral, or any interest which the Borrower may have therein.
After deducting from the proceeds of sale or other disposition of the Collateral
all expenses (including all reasonable expenses for legal services), the Agent
shall apply such proceeds toward the satisfaction of the Obligations. Any
remainder of the proceeds after satisfaction in full of the Obligations shall be
distributed as required by applicable Laws. Notice of any sale or other
disposition shall be given to the Borrower at least ten (10) days before the
time of any intended public sale or of the time after which any intended private
sale or other disposition of the Collateral is to be made, which the Borrower
hereby agrees shall be reasonable notice of such sale or other disposition. The
Borrower agrees to assemble, or to cause to be assembled, at its own expense,
the Collateral at such place or places as the Banks shall designate. At any such
sale or other disposition, the Banks may, to the extent permissible under
applicable Laws, purchase the whole or any part of the Collateral, free from any
right of redemption on the part of the Borrower, which right is hereby expressly
waived and released.

                  Without limiting the generality of any of the rights and
remedies conferred upon the Agent and/or Banks under this Paragraph 8.3, the
Agent and/or Banks may, to the full extent permitted by applicable Laws:

                  (a) Enter upon the premises of the Borrower, exclude therefrom
the Borrower, any Subsidiary or any Affiliate thereof, and take immediate
possession of the Collateral, either personally or by means of a receiver
appointed by a court of competent jurisdiction, using all necessary and lawful
self-help to do so;

                  (b) At the Banks' option, use, operate, manage and control the
Collateral in any lawful manner;


                                       46

<PAGE>   47


                  (c) Collect and receive all receivables, rents, income,  
revenue, earnings, issues and profits therefrom; and

                  (d) Maintain, repair, renovate, alter or remove the Collateral
as the Banks may determine in their discretion.


                              SECTION 9. THE AGENT

         This Section 9 is between and among the Agent and the Banks only.
Except as specifically set forth in Paragraph 9.8 below, neither the Borrower
nor any other creditor of the Borrower shall have any rights under this section,
whether as a third party beneficiary or otherwise, and this section may be
amended by the Agent and the Banks acting alone.

         9.1 Authorization. Each Bank authorizes the Agent to act on behalf of
such Bank or holder to the extent provided herein or in any document or
instrument delivered hereunder or in connection herewith and signed by such
Bank, and to take such other action as may be reasonably incidental thereto. The
Agent shall be considered as acting solely in an administrative and ministerial
capacity, not as trustee or other fiduciary of the Banks. The Agent shall not be
construed as having any agency or fiduciary relationship with the Borrower. The
Agent shall not have any duties or obligations to the Banks other than those
expressly provided for herein. The Agent shall not be required to exercise any
discretion or take any action, but shall be fully protected in so acting or in
refraining from acting, upon the instructions of the Majority Banks (except as
otherwise provided in Paragraph 10.3, for matters which require the consent of
all Banks), and such instructions shall be binding upon all Banks holders of the
Notes, and the Agent shall not be liable to any party hereto for any consequence
of any such action or refraining from action. Notwithstanding any instructions
of the Majority Banks, the Agent shall not be required to take any action that
exposes the Agent to personal liability or that is contrary to any loan document
or applicable law.

         9.2 Standard of Care. Neither the agent nor any of its officers,
directors, agents, employees or representatives shall be liable for any action
taken or omitted to be taken by it or any of them under or in connection with
this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the Agent:
(a) may treat the payee of any Notes as the holder thereof and as a Bank
hereunder until the Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to the Agent (which notice
shall be binding on all parties thereto); (b) may consult with legal counsel,
independent public accounts and other experts and advisors selected by it 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 other advisors;
(c) makes no warranty or representation to any Bank and shall not be responsible
to any Bank for any statements, warranties or representations made in or in
connection with this Agreement or for any failure or delay in performance by the
Borrower or any Bank under this Agreement; (d) shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the terms,
covenants or conditions of this Agreement; (e) shall not be responsible to any
Bank for the due execution, legality, validity, enforceability, perfection,
collectibility, genuineness, sufficiency or value of this Agreement, the Notes,
or any other 




                                       47

<PAGE>   48


instrument or document furnished pursuant thereto or for the accuracy or
completeness of any credit or other information provided to the Banks; (f) shall
incur no liability under or in respect of this Agreement by acting upon any
notice, consent, certificate of other instrument or writing (which may be by
telecopier, telegram, cable or telex) believed by it to be genuine and signed or
sent by the proper party or parties; and (g) shall incur no liability for
relying upon any matters of fact that might reasonably be expected to be within
the knowledge of the Borrower, upon a certificate or other writing signed by
Borrower, or upon telephone communications with Borrower which are reasonably
believed to be true and value.

         9.3 No Waiver of Rights. With respect to the Notes, the Agent shall
have the same rights and powers hereunder as any other Bank and may exercise the
same as though it were not the Agent, and the Agent may accept deposits from,
and generally engage in any kind of business with, the Borrower.

         9.4 Payments. The Agent shall use its best efforts to deliver to each
Bank on the same day as received by Agent in immediately available funds such
Bank's pro rata share of all payments received by the Agent for the benefit of
the Banks, but in the event Agent is unable to deliver such payments to any Bank
on the same day of receipt, Agent agrees to pay such Bank interest on the
payment for each day the Agent is unable to deliver the payments after the date
of its receipt based on the overnight Federal Funds Rate of interest. Any
payment due for any reason under this Agreement that is required to be made on a
date on which the Agent is not open for business shall be extended until the
next day on which the Agent is open for the transaction of business. The Agent
shall make available to any Bank for inspection, upon reasonable request, the
Agent's records with respect to all sums received or disbursed by the Agent in
connection with the Loans and the Loan Documents. The Agent shall provide to any
Bank, upon request, information as to the amount of the then outstanding Loans.

         9.5 Indemnification. The Agent shall not be required to do any act
hereunder or under any other document or instrument delivered hereunder or in
connection herewith or take any action toward the execution or enforcement of
the agency hereby created, or to prosecute or defend any suit in respect of this
Agreement or the Notes or to advance funds hereunder upon the failure by any
Bank to fund its pro rata share of the Commitment hereunder, unless ratably
indemnified to its satisfaction (to the extent not reimbursed by Borrower) by
the holders of the Not against loss, cost, liability and expense (including
reasonable fees and out-of-pocket expenses of counsel), claim, demand, action,
loss or liability (except such as result from Agent's gross negligence or
willful misconduct) that Agent may suffer or incur in connection with this
Agreement or any action taken or omitted by Agent hereunder. If any indemnity
furnished to the Agent for or against any loss, cost, liability, and expense or
for any purpose shall, in the opinion of ht Agent, be insufficient or become
impaired, the Agent may call for additional indemnify and not commence or cease
to do the acts indemnified against until such additional indemnity is furnished.
Each Bank agrees to reimburse the Agent promptly upon demand for such Bank's pro
rata share of any expenses referred to in Paragraph 10.4 incurred by the Agent
to the extent that the Agent is not reimbursed for such expenses by the
Borrower.

         9.6 Exculpation. Neither Agent nor any of its directors, officers,
employees or agents shall be liable for any action taken or not taken by it in
connection herewith (a) with the consent or 



                                       48

<PAGE>   49


at the request of the Banks or Majority Banks, as appropriate, or (b) in the
absence of its own gross negligence or willful misconduct. Neither Agent nor any
of its directors, officers, employees or agent shall (i) be responsible for any
recitals, representations or warranties contained in, or for the execution,
validity, genuineness, effectiveness or enforceability of this Agreement, any
Note or any other instrument or document delivered hereunder or in connection
herewith, or (ii) be under any duty to inquire into or pass upon any of the
foregoing matters, or to make any inquiry concerning the performance by Borrower
or any other obligor of its obligations.

         9.7 Credit Investigation. Each Bank acknowledges that it has made such
inquiries and taken such care of its own behalf as would have been the case had
the Commitment been granted and the Loan made directly by such Bank to the
Borrower. Each Bank agrees and acknowledges that the Agent makes no
representations or warranties about the creditworthiness of the Borrower or any
other party to this Agreement or with respect to the legality, validity,
sufficiency or enforceability of this Agreement, the Notes or the value of any
security therefor and that each Bank has not entered into this Agreement in
reliance upon any action, statement, representation, or warranty of any other
Bank or Agent. Each Bank agrees that it will, independently and without reliance
upon the Agent or any other bank and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement. Neither the Agent nor any
other Bank shall have any obligation whatsoever to make any such credit analysis
or decisions for a Bank or to provide any credit or other information with
respect to the Borrower nor or in the future in the possession of the Agent or
such other Bank, except that the Agent shall promptly forward to the Banks a
copy of any notice received by the Agent from the Borrower of the occurrence of
an Event of Default hereunder and copies of all material documents delivered to
it by the Borrower pursuant to the terms hereof.

         9.8 Resignation. The Agent may resign at any time as the Agent under
this Agreement by giving written notice thereof to the Banks and the Borrower,
which resignation shall be effective upon a successor Agent's acceptance of its
appointment. Upon any such resignation, the Majority Banks shall have the right
to appoint a successor Agent hereunder; provided, if the successor Agent is not
already a Bank hereunder, the Majority Banks must also obtain the consent of the
Borrower, which shall not be unreasonably withheld. If no such successor Agent
shall have been so appointed by the Majority Banks, or Borrower shall have
reasonably rejected such appointment, within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be a commercial bank
organized under the laws of the United States of America or of any State thereof
having assets of at least One Billion and 00/100 Dollars ($1,000,000,000.00),
and which shall be reasonably acceptable to the Borrower. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder After any retiring Agent's
resignation as an Agent hereunder, the provisions of this Section 9 shall inure
to the benefit as to any actions taken or omitted to be taken by it while it was
an Agent under the Loan Documents.

         9.9 Proration of Payments. Except as may be provided in other sections
of this Agreement, all funds received by Banks, or any of them, shall be
allocated pro rata among all Banks in proration to their respective share of
outstanding Loan balances. If any Bank or other holder of




                                       49

<PAGE>   50


any Notes shall obtain any payment or other recovery (whether voluntary,
involuntary, by application of offset, or otherwise) on account of principal of
or interest on the Note then held by it in excess of its pro rata share of
payments and other recoveries obtained by all Banks or other holders on account
of principal of and interest on the Notes then held by them, such Bank or other
holder shall purchase from the other Banks or holders such participation in the
Notes held by them as shall be necessary to cause such purchasing Bank or other
holder to share the excess payment or other recovery ratably with each of them;
provided, however, if all or any portion of the excess payment or other recovery
is thereafter recovered from such purchasing holder, the purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest. Notwithstanding the foregoing, no Bank shall have any
obligation to account for or share any amount, property or profit of any kind
received by it for its own account arising out of a banking or other
relationship with the Borrower apart from the obligations under the Loan
Documents.

         9.10 No Liability for Errors. The Agent shall not be liable for any
error in computing the amounts payable to any Bank in respect of any amounts due
to the Banks hereunder or in making payment of such amounts. In the event of an
error in computing any amount payable to any Bank or in the making of a payment,
the Agent, the Borrower and such Bank shall, forthwith upon discovery of such
error, make such adjustment as shall be required to correct such error,
including the payment of interest on any amounts that were incorrectly paid or
not paid from the date paid or of the date due to the date returned or paid, all
as the case may be, at the daily rate for the overnight sale of Federal Funds by
the Agent in effect for such period.

         9.11 Offset. In addition to and not in limitation of all rights of
offset that any Bank or other holder of any Note may have under applicable Laws,
each Bank or other holder of a Not shall, upon the occurrence of any Event of
Default described in this Agreement or in the Note in question, shall have the
right to appropriate and apply to the payment of such Notes any and all
balances, credits, deposits, accounts or moneys of the Borrower then or
thereafter with such Bank or other holder; provided, however, all funds received
as a result of such offsets shall be applied pro rata among the Banks in
proportion to the respective outstanding Loan amounts. Each Bank agrees to
notify to the Borrower and other Banks immediately after the exercise by it of
this right of offset.


                            SECTION 10. MISCELLANEOUS

         10.1 Construction. The provisions of this Agreement shall be in
addition to those of any guaranty, pledge or security agreement, note or other
evidence of liability held by the Banks, all of which shall be construed as
complementary to each other; provided, in the event of any inconsistency, the
provisions of this Agreement shall control. Nothing herein contained shall
prevent the Banks from enforcing any or all other notes, guaranties, pledge or
security agreements in accordance with their respective terms.

         10.2 Further Assurance.  From time to time, the Borrower will execute 
and deliver to the Banks such additional documents and will provide such
additional information as the Banks may reasonably require to carry out the
terms of this Agreement and be informed of the Borrower's operations, business
and condition



                                       50

<PAGE>   51



         10.3 Enforcement and Waiver by the Banks. The Majority Banks shall have
the sole and exclusive right to administer, amend, or modify the Loan Documents,
and are hereby empowered to act for the Banks with regard to the aggregate
Commitments and the documentation thereof as if said Majority Banks were the
sole lenders or extenders of credit under the Loan Documents; provided, however,
that it shall take an affirmative vote of all Banks to: (i) increase any of the
several Commitments; (ii) decrease any of the interest rates or fees on the
Loans; (iii) extend the Loan Termination Date; (iv) reduce or postpone the
principal payments due on any Loans; (v) postpone any payments of interest or
interest payment dates; (vi) release Collateral having a value greater than
fifteen percent (15%) of the total book value of the Collateral, either in a
single transaction or in a series of related transactions consummated over a six
(6) month period; (vii) amend the definition of Majority Banks; and (viii) amend
this Paragraph 10.3. The Banks shall have the right at all time to enforce the
provisions of the Loan Documents in strict accordance with the terms thereof,
notwithstanding any conduct or custom on the part of the Banks and/or Agent in
refraining from so doing at any time or times. The failure of the Banks at any
time or times to enforce their rights under such provisions, strictly in
accordance with the same, shall not be construed as having created a custom in
any way or manner contrary to specific provisions of the Loan Documents or as
having in any way or manner modified or waived the same. All rights and remedies
of the Banks are cumulative and concurrent and the exercise of one right or
remedy shall not be deemed a waiver or release of any other right or remedy.

         10.4 Expenses of the Banks. The Borrower will, on demand, reimburse the
Agent and the Banks for all out-of-pocket expenses, including the reasonable
fees and expenses of legal counsel for the Agent and the Banks, incurred by the
Agent and the Banks in connection with the preparation, administration,
amendment, modification, or enforcement of the Loan Documents and the collection
or attempted collection of the Notes.

         10.5 Notices. Any notices or consents required or permitted by this
Agreement shall be in writing and shall be deemed delivered when delivered in
person, or when sent by certified mail, postage prepaid, return receipt
requested, by overnight courier service, or by facsimile to the address and/or
telecopy number as follows, unless such address or number is changed by written
notice hereunder.

applicable Laws, the Borrower:

held by the Banks on which the Borrower or any Subsidiary is in any way liable;

required hereby or by any applicable Laws, notice of any other action taken by
the Banks; and

                  (b) Releases the Agent, the Banks, and their officers,

<PAGE>   53



         10.7 Indemnification. Without limiting the provisions of Paragraph
10.4, Borrower hereby indemnifies and holds the Agent, the Banks, and their
officers, directors, attorneys, employees and agents free and harmless from and
against any and all actions, causes of action, suits, losses, liabilities and
damages, and expenses in connection therewith, including, without limitation,
reasonable counsel fees and disbursements, incurred by the Agent, the Banks or
any of them as a result of, or arising out of, or relating to the execution,
delivery, performance or enforcement of the Loan Documents or any instrument
contemplated therein, except for the Agent's or any Bank's gross negligence or
willful misconduct. If and to the extent that the foregoing undertaking may be
unenforceable for any reason, Borrower and each Subsidiary thereby agrees to
make the maximum contribution to the payment and satisfaction of such
liabilities and costs permitted under applicable Laws.

         10.8     Participations and Assignments.

                  (a) This Agreement and the other Loan Documents shall be
binding upon and inure to the benefit of Borrower, Banks, and Agent and their
respective successors and assigns; provided, however, that Borrower may not
assign, transfer or delegate any of its rights, duties or obligations under this
Agreement or the other Loan Documents without the prior written consent of Agent
and Banks. Banks may assign, sell and transfer their interests, rights and
obligations under this Agreement and the other Loan Documents only in accordance
with this Paragraph 10.8.

                  (b) With the prior written consent of the Agent and the
Borrower, any Bank may assign to one or more Eligible Assignees all, or a
proportionate part of all, of its interests, rights and obligations under this
Agreement and the other Loan Documents; provided, however, that (i) each such
assignment shall be of a constant, and not a varying, percentage of all of the
assigning Bank's interests, rights and obligations under this Agreement, (ii)
the amount of each such assignment (determined as of the date the Assignment and
Acceptance with respect to such assignment) shall not be less than the lesser of
(A) the entire amount of such Bank's Loans or (B) the principal amount of
$3,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) no
more than three (3) Banks may be parties hereto without first obtaining the
prior written consent of the Agent and Borrower; and (iv) the parties to each
such assignment shall execute and/or deliver to Agent, for its acceptance and
recording in the Register, and Assignment and Acceptance, together with the
Notes subject to such assignment, and a processing and recordation fee of $2,500
payable to Agent. Upon such execution, delivery, acceptance and recording, from
and after the "Effective Date" specified in the Assignment and Acceptance, which
"Effective Date, " unless Agent otherwise agrees, shall be not earlier than five
Business Days after the date of acceptance and recording by Agent (provided,
however, that, as between the assigning Bank and the assignee thereunder only,
the effective date shall be the effective date of execution and delivery as
between such Persons as specified in the Assignment and Acceptance), (A) the
assignee thereunder shall be a Bank under this Agreement and, to the extent
provided in such Assignment and Acceptance, have the interests, rights and
obligations of a Bank hereunder and (B) the assigning Bank thereunder shall, to
the extent provided in such Assignment and Acceptance, be released from its
contractual obligations under this Agreement (and, in the case of an Assignment
and Acceptance covering all or the remaining portion of the assigning Bank's
interests, rights and obligations under this Agreement, such assigning Bank
shall cease to be a Bank under this Agreement). Each Bank shall, in a reasonably
prompt fashion after it has engaged in any material discussions with an Eligible
Assignee that may lead to an assignment referred to in 




                                       53

<PAGE>   54


this Paragraph 10.8, notify Agent and Borrower of the identity of such Eligible
Assignee so that they will have sufficient time to determine if they are willing
to consent.

                  (c) By executing and delivering an Assignment and Acceptance,
the assigning Bank thereunder and the Eligible Assignee thereunder shall be
deemed to confirm to and agree with each other and the other parties hereto as
follows: (i) such assignee is an Eligible Assignee; (ii) other than as provided
in the Assignment and Acceptance, such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to any representations,
warranties or other statements made in or in connection with this Agreement or
any other Loan Document or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other Loan Document
or any Collateral; (iii) such assigning Bank makes no representation or warranty
and assumes no responsibility with respect to the financial conditions of
Borrower or any Subsidiary or the performance or observance by Borrower or any
Subsidiary of any of its obligations under this Agreement or any other Loan
Document; (iv) such assignee confirms that it has received a copy of this
Agreement, together with copies of the most recent Financial Statements and such
other agreements, documents, instruments, certificates and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (v) such assignee will independently and without
reliance upon Agent, such assigning Bank or any other Bank and based on such
agreements, documents, instruments, certificates and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement and the other Loan Documents;
(vi) such assignee appoints and authorizes Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement and the other Loan
Documents as are delegated to the Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; (vii) such assignee agrees that it
will perform in accordance with their terms all the obligations which by the
terms of this Agreement and the other Loan Documents are required to be
performed by it as a Bank; and (viii) such assignee makes loans in the ordinary
course of its business.

                  (d) Upon its receipt of an Assignment and Acceptance executed
by an assigning Bank and an Eligible Assignee and the required processing and
recordation fee, Agent shall, if such Assignment and Acceptance is duly
completed and is in the required form, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to Banks and Borrower. Within five Business
Days after its receipt of any such notice from Agent, Borrower, at its own
expense, shall execute and deliver to Agent, in exchange for the surrendered
Note or Notes, a new Note or Notes payable to the order of such assignee in the
appropriate principal amount(s) evidencing such assignee's assigned Loans and
Commitments, and, if the assignor Bank has retained a portion of its Loans and
Commitments, a new Note or Notes payable to the order of such assignor in the
appropriate principal amount(s) evidencing such assignor's Loans and Commitments
retained by it. Such new Note(s) shall be dated the date of the surrendered
Note(s) which they replace and shall otherwise be in substantially the form of
the surrendered Notes, as appropriate.

                  (e) Each Bank may, without the consent of Borrower, any
Subsidiary or Agent, sell participations to one or more banks in all or a
portion of its interests, rights and obligations under this Agreement (including
all or a portion of its Loans or Commitments) held by it; provided, however,
that (i) such Bank shall remain a Bank for all purposes of this Agreement and
the 



                                       54

<PAGE>   55


transferee of such participation shall not constitute a Bank under this
Agreement, (ii) such Bank's obligations under this Agreement shall remain
unchanged, (iii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iv) the participating banks or
other entities shall be entitled to the benefit of the provisions contained in
Paragraphs 2.6 and 2.7 to the same extent as if they were Banks, except that no
such participant shall be entitled to receive any greater benefit pursuant to
Paragraph 2.6 than its assignor Bank would have been entitled to receive with
respect to the rights participated, and (v) Borrower, Subsidiaries, Agent and
the other Banks shall continue to deal solely and directly with such Bank in
connection with such Bank's interests, rights and obligations under this
Agreement, and such Bank shall retain the sole right to enforce the obligations
of Borrower of any provision of this Agreement, provided that such participation
agreement may provide that such Bank will not agree to any amendment,
modification or waiver of this Agreement or the other Loan Documents, without
the consent of such participant, that would (A) reduce the principal or the rate
of interest payable by Borrower on any Loan or reduce any fees payable by
Borrower, (B) postpone any date fixed for the payment of principal of or
interest on the Loans or any fees payable by Borrower, (C) increase any
Commitment of any Bank or subject any Bank to any obligation to make Loans, or
(D) amend Paragraph 10.3, 10.8(E) or any other provision of this Agreement
requiring the consent or other action of all Banks.

                  (f) Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Paragraph
10.8, disclose to the assignee or participant or proposed assignee or
participant any information relating to Borrower or any Subsidiary, the
Collateral or the Loan Documents furnished to such Bank by or on behalf of the
Borrower or any Subsidiary; provided, however, that, prior to any such
disclosure, each such assignee or participant or proposed assignee or
participant shall execute an agreement whereby such assignee or participant
shall agree (subject to customary exceptions) to preserve the confidentiality of
any non-public information received from such Bank.

                  (g) If (i) any Bank has demanded compensation under Paragraph
2.9 in an aggregate amount exceeding $5,000 during any calendar year, (ii) it
becomes unlawful, impossible or impractical for any Bank to make or continue to
maintain Eurodollar Loans pursuant to Paragraph 2.8 and such circumstance is not
applicable to NationsBank, or (iii) any Bank is or becomes insolvent or a
receiver, conservator or similar authority is appointed for any Bank, then Agent
and/or Borrower shall have the right, but not the obligation, upon notice to
such Bank and Borrower or Agent, as applicable, to designate, with the consent
of such assignee, an assignee for any such Bank, which assignee shall be an
Eligible Assignee mutually satisfactory to Agent and Borrower, to purchase such
Bank's Loans and Commitments and assume such Bank's obligations; provided,
however, that Borrower shall not have the right to designate any assignee for
NationsBank. Within ten Business Days after any such notice to such Bank and
Borrower or Agent, as applicable, such Bank shall be obligated to sell its Loans
and Commitments, and such assignee shall be obligated to purchase such Loans and
assume such Bank's obligations, pursuant to an Assignment and Acceptance. The
purchase price therefor shall be an amount equal to the sum of (A) the
outstanding principal amount of the Loans payable to such Bank, plus (B) all
accrued and unpaid interest on such Loans, plus (C) all accrued and unpaid fees
and other amounts due to such Bank pursuant to this Agreement.

                  (h) Notwithstanding anything to the contrary contained in this
Paragraph 10.8, any Bank may at any time or from time to time assign as
collateral all or any portion of its rights under this Agreement with respect to
its Loans, Commitments and Notes to a Federal Reserve Bank. No such assignment
shall release the assigning Bank from its obligations under this Agreement.

         10.9 Confidentiality. Agent and each Bank agree (on behalf of itself
and each of its Affiliates, directors, officers, employees and representatives)
to use reasonable precautions to keep confidential, in accordance with customary
procedures for handling confidential information of the nature involved and in
accordance with safe and sound banking practices, any non-public information
supplied to it by Borrower or any Subsidiary pursuant to this Agreement,
provided that Agent and each Bank may disclose (and shall not be required to
keep confidential) such non-public information (a) to the extent authorized by
Borrower or any Subsidiary, (b) to the extent required by law, rule, regulations
or judicial process of any tribunal, (c) to its counsel or to other agents in
connection with this Loan, (d) to bank examiners, regulators, auditors or
accountants, (e) to Agent or any other Bank, (f) in connection with any action,
suit or proceeding to which it or any one or more of Banks is a party, (g) to
any assignee or participant (or prospective assignee or participant) or
Affiliate of a Bank so long as such assignee or participant (or prospective
assignee or participant) or Affiliate agrees to preserve the confidentiality of
any non-public information to the extent required of Banks pursuant to this
Paragraph 10.9, (h) which has become public knowledge through no violation of
this Agreement, (i) to the extent such information becomes available through a
Person other than Borrower or a Subsidiary without knowledge by Agent or such
Bank (as the case may be) of any requirements of, Agent or such Bank, as the
case may be, without restriction on disclosure thereof at the time such
information was supplied by Borrower or any Subsidiary, or (k) to the extent
such information is also furnished to Agent or any Bank by a third party not
having any similar duty of confidentiality to Borrower. Except as otherwise
provided in the immediately preceding sentence, all such non-public information
supplied to Agent or any Bank shall not be copied or distributed to any Person
other than Agent and Banks without the prior written consent of Borrower. The
obligations of confidentiality under this Paragraph 10.9 shall supersede and
replace the obligations of Agent and each Bank under any confidentiality letter
or other confidentiality agreement in respect of this financing initially signed
and delivered to Borrower prior to the date hereof.

         10.10 Applicable Laws. The Laws of the State of Tennessee, other than
its conflicts of laws rules, shall govern the construction and interpretation of
this Agreement and the validity and enforceability of this Agreement, and of its
provisions and the transactions pursuant to this Agreement, except for those
transactions for which the parties have chosen other laws to govern or for which
other mandatory choice of law rules apply.

         10.11 Binding Effect, Assignment and Entire Agreement. This Agreement
shall inure to the benefit of, and shall be binding upon, the respective
successors and permitted assigns of the parties hereto. The Borrower has no
right to assign any of its rights or obligations hereunder without the prior
written consent of the Banks. This Agreement and the documents executed and
delivered pursuant hereto constitute the entire agreement between the parties,
and supersede all prior agreements and understandings among the parties hereto.
This Agreement may be amended only by a writing signed on behalf of each party.

         10.12 Severability. If any provision of this Agreement shall be held
invalid under any applicable Laws, such invalidity shall not affect any other
provision of this Agreement that can be given effect without the invalid
provision, and, to this end, the provisions hereof are severable.

         10.13 Counterparts. This Agreement may be executed by the parties
independently in any number of counterparts, all of which together shall
constitute but one and the same instrument which is valid and effective as if
all parties had executed the same counterpart.

         10.14 Venue. It is agreed that venue for any action arising in
connection with this Agreement or the Obligations secured hereby shall lie
exclusively with courts sitting in the State of Tennessee, unless the Banks and
Agent otherwise agree in writing.

         10.15 Arbitration. Any controversy or claim between or among the
parties hereto including, but not limited to, those arising out of or relating
to this instrument, agreement or document or any related instruments, agreements
or documents, including any claim based on or arising from an alleged tort,
shall be determined by binding arbitration in accordance with the Federal
Arbitration Act (or if not applicable, the applicable state law), the Rules of
Practice and Procedure for the Arbitration of Commercial Disputes of
J.A.M.S./Endispute or any successor thereof ("J.A.M.S."), and the "Special
Rules" set forth below. In the event of any inconsistency, the Special Rules
shall control. Judgment upon any arbitration award may be entered in any court
having jurisdiction. Any party to this Agreement may bring an action, including
a summary or expedited proceeding, to compel arbitration of any controversy or
claim to which this Agreement applies in any court having jurisdiction over such
action.

                  (a) Special Rules. The arbitration shall be conducted in the
city of the Borrower's domicile at time of the execution of this instrument,
agreement or document and administered by J.A.M.S. who will appoint an
arbitrator; if J.A.M.S. is unable or legally precluded from administering the
arbitration, then the American Arbitration Association will serve. All
arbitration hearings will be commenced within 90 days of the demand for
arbitration; further, the arbitrator shall only, upon a showing of cause, be
permitted to extend the commencement of such hearing for up to an additional 60
days.

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