1. BASIS OF PREPARATION
 
    The accompanying unaudited condensed consolidated financial statements have
been prepared by Alliance Imaging, Inc. ("the Company") 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 of the
Securities and Exchange Commission. 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 the Company, all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included. Operating results for the nine month
period ended September 30, 1998 are not necessarily indicative of the results
that may be expected for the year ending December 31, 1998. 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.
 
    The provision for income taxes for the nine month period ended September 30,
1998 is higher than the statutory federal rate primarily as a result of
non-deductible goodwill amortization expense. The provision for income taxes for
the nine month period ended September 30, 1997 is less than the statutory
federal rate due to the utilization of certain net operating loss carryforwards
during the period.
 
    Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income," ("SFAS 130")
which establishes standards for reporting and displaying comprehensive income
and its components in the financial statements. For the nine months ended
September 30, 1998 and 1997, the Company did not have any components of other
comprehensive income as defined in SFAS 130.

2. ACQUISITIONS
 
    On March 12, 1998, the Company acquired Mobile Technology Inc. ("MTI"). The
purchase price consisted of $58,300 for all of the equity interests in MTI, plus
direct acquisition costs of approximately $2,000. In connection with the
acquisition, the Company also refinanced $37,400 of MTI's outstanding debt and
paid MTI direct transaction costs of $3,500. To finance these expenditures, the
Company increased its existing term loan facility by $20,000 to provide total
availability of $70,000, established a new $50,000 term loan facility and
borrowed an aggregate of $90,000 thereunder, for which the Company incurred debt
issuance costs of approximately $2,800. The Company also borrowed $5,400 under
its revolving loan facility and used $8,500 of cash on hand at MTI to complete
the financing requirements. The acquisition has been accounted for as a purchase
and, accordingly, the results of operations of MTI have been included in the
Company's consolidated financial statements from the date of acquisition. The
goodwill recorded as a result of this acquisition was approximately $79,000,
which is being amortized on a

    Also on March 12, 1998, the Company announced it had signed a definitive
agreement to acquire all of the equity interests in two operating subsidiaries
of American Shared Hospital Services ("American Shared"), which provide
diagnostic imaging services, for approximately $13,600 in cash and assumption of
approximately $23,000 of debt. On November 3, 1998, the Company was notified
that the U. S. Federal Trade Commission had concluded its review regarding the
Company's purchase of American Shared. No changes in the terms of the
transaction resulted from the review. The sale is now subject to the approval of
a majority of the shareholders of American Shared. American Shared has scheduled
a Special Meeting of Shareholders to be held on November 13, 1998 to consider
approval of the sale. The sale is expected to close promptly after the November
13 Shareholder Meeting.
 
    On May 19, 1998, the Company acquired Medical Diagnostics, Inc. ("MDI"), a
subsidiary of U. S. Diagnostic, Inc. The purchase price consisted of
approximately $31,000 plus the assumption of approximately $5,900 in financing
arrangements. The Company borrowed $30,000 under its revolving loan facility to
finance the transaction. The acquisition has been accounted for as a purchase
and, accordingly, the results of operations of MDI have been included in the
Company's consolidated financial statements from the date of acquisition. The
goodwill recorded as a result of this acquisition was approximately $25,400 and
is being amortized on a straight-line basis over 20 years. The allocation of the
MDI purchase price is tentative pending completion of fair value determinations
for the net assets acquired. The allocation may change with the completion of
these determinations.

ITEM 2 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS
 
OVERVIEW
 
    The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides magnetic resonance imaging ("MRI") systems and services to
hospitals and other health care providers on a mobile, shared user basis. The
Company also provides dedicated, full-time MRI systems and services as well as
full-service management of imaging operations for selected hospitals. The
Company's services enable small to mid-size hospitals to gain access to advanced
diagnostic imaging technology and related value-added services without making a
substantial investment in equipment and personnel. The Company operates a fleet
of 214 MRI systems and services 836 customers in 43 states as of September 30,
1998.
 
    The Company's revenues are principally a function of the number of systems
in service, scan volumes and fees per scan. The Company generates substantially
all of its revenues under exclusive one to eight-year contracts with hospitals
and health care providers. The Company's contracts typically offer tiered
pricing with lower fees per scan on incremental scans, allowing customers to
benefit from increased scan volumes and the Company to benefit from the
operating leverage associated with increased scan volumes. The Company expects
modest continuing downward pressure on pricing levels as a result of cost
containment measures in the health care industry. However, in many cases higher
scan volumes justify lower prices on incremental scans.
 
    The principal components of the Company's operating costs include salaries
paid to technologists and drivers, annual system maintenance costs, insurance
and transportation costs. Because a majority of these expenses are fixed,
increased revenues as a result of higher scan volumes significantly improve the
Company's profitability while lower scan volumes result in lower profitability.
 
    Since the beginning of 1995, the Company has substantially increased
revenues by adding new customers and increasing scan volumes at existing
customer sites. The Company has also substantially increased revenue through
acquisitions. During the same period, the growth rate of the Company's EBITDA
(income before income taxes, plus depreciation, amortization and net interest
expense), excluding expenses associated with the Recapitalization Merger (as
hereinafter defined), has exceeded the growth rate of revenues as a result of
spreading costs (which are primarily fixed) over a larger revenue base and
implementing cost reduction and containment measures.
 
    The Company has historically focused on maximizing cash flow and return on
invested capital nationwide, deploying new and upgraded systems in high volume
markets and redeploying older, less advanced systems with lower carrying values
in lower volume markets. The Company's ongoing equipment trade-in and upgrade
program has substantially improved the marketability and productivity of its MRI
systems. Because the Company owns substantially all of its MRI systems, it
periodically evaluates its older, less marketable MRI systems to determine if it
is more beneficial to continue to use such systems in lower volume markets which
are profitable but produce less revenue, or to trade in such equipment in
connection with new system purchases. The Company currently maintains one of the
most advanced fleets in the industry.
 
    The Company also provides computed tomography ("CT") services, lithotripsy
services, nuclear medicine services, and other imaging services. Revenues from
CT services, lithotripsy services, nuclear medicine services, and other imaging
services accounted for approximately 7% of the Company's revenues for the nine
months ended September 30, 1998.
 
    On November 21, 1997, the Company acquired Medical Consultants Imaging Co.
("MCIC"), a Cleveland, Ohio based provider of mobile MRI services, CT services
and other outsourced health care services. The acquisition also included MCIC's
one-half interest in a limited liability company in Michigan. The purchase price
consisted of $12.3 million cash plus the assumption of approximately $5.5
million in
 
                                       10
<PAGE>
financing arrangements. MCIC operated 14 mobile MRI systems and several other
diagnostic imaging systems, primarily in Ohio, Michigan, Indiana and
Pennsylvania.
 
    On December 18, 1997, after obtaining the approval of stockholders, the
Company completed a series of transactions contemplated by an Agreement and Plan
of Merger between Newport Investment LLC (the "Investor") and the Company (the
"Recapitalization Merger") whereby the Company: obtained proceeds from debt
financing aggregating $215.0 million; issued 150,000 shares of non-voting
redeemable Series F preferred stock to the Investor for proceeds of $15.0
million; issued 3,632,222 shares of its common stock in exchange for all of the
outstanding stock of Newport Acquisition Corporation, a subsidiary of the
Investor, and received net proceeds of $40.0 million from cash placed into
Newport Acquisition Corporation by the Investor; and converted all shares of its
common stock held by existing stockholders in excess of 411,358 shares that were
retained by electing existing stockholders into the right to receive $11 in
cash.
 
    As a result of these transactions, the Company experienced an approximate
90% ownership change. The Investor, which was formed and is wholly owned by
certain affiliates of Apollo Management, L.P., ("Apollo") obtained ownership of
approximately 83.6% of the Company's outstanding common stock, and the Company
became highly leveraged.
 
    On March 12, 1998, the Company acquired Mobile Technology Inc. ("MTI"),
which management believes was the second largest provider of mobile MRI services
in the United States, in a transaction accounted for as a purchase. The Company
has included the operations of MTI in its consolidated financial statements from
the date of acquisition. This acquisition added 68 MRI systems operating in 31
states, 3 CT systems, 9 lithotripsy systems, and 3 brachytherapy systems to the
Company's equipment fleet. The purchase price consisted of $58.3 million for all
of the equity interests in MTI plus direct acquisition costs of approximately
$2.0 million. In connection with the acquisition, the Company also refinanced
$37.4 million of MTI's outstanding debt and paid MTI direct transaction costs of
$3.5 million. To finance these expenditures, the Company increased its existing
term loan facility by $20.0 million to provide total availability of $70.0
million, established a new $50.0 million term loan facility and borrowed an
aggregate of $90.0 million thereunder, for which the Company incurred debt
issuance costs of approximately $2.8 million. The Company also borrowed $5.4
million under its revolving loan facility and used $8.5 million of cash on hand
at MTI to complete the financing requirements. The goodwill recorded as a result
of this acquisition was approximately $79.0 million, which is being amortized on
a straight-line basis over 20 years. The allocation of the MTI purchase price is
tentative pending completion of fair value determinations for the net assets
acquired. The allocation may change with the completion of these determinations.
 
    On May 19, 1998, the Company acquired Medical Diagnostics, Inc. ("MDI"), a
subsidiary of U. S. Diagnostic, Inc. The purchase price consisted of
approximately $31.0 million plus the assumption of approximately $7.4 million in
financing arrangements. The Company borrowed $30.0 million under its revolving
loan facility to finance the transaction. The acquisition has been accounted for
as a purchase and, accordingly, the results of operations of MDI have been
included in the Company's consolidated financial statements from the date of
acquisition. The goodwill recorded as a result of this acquisition was
approximately $25.4 million and is being amortized on a straight-line basis over
20 years. The allocation of the MDI purchase price is tentative pending
completion of fair value determinations for the net assets acquired. The
allocation may change with the completion of these determinations.
 
RESULTS OF OPERATIONS
 
    NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1997 -- Revenues for the first nine months of 1998 were $138.7 million, an
increase of $76.4 million, or 122.7%, over 1997, primarily due to the MTI and
MDI acquisitions. These acquisitions accounted for approximately $49.7 million
of the increase. The remaining increase reflects higher scan-based MRI revenue,
MRI revenue under fixed fee contracts and other revenue items (including revenue
for other modalities). Overall, MRI revenue increased $63.0 million, as a result
of a 18.6% increase in total scan volume partially offset by a
 
                                       11
<PAGE>
3.6% decrease in the average revenue realized per MRI scan. The average daily
scan volume per MRI system increased 15.3% to 8.3 from 7.2 in 1997. Management
attributes the non-acquisition volume increase to the Company's continuing MRI
systems upgrade program, which has enabled the Company to obtain new, long-term
contracts from both existing and new customers, and to the continuing positive
effect of marketing programs implemented in early 1997. Management believes the
decrease in average revenue realized per scan is the result of many customers
achieving discount price levels in incremental scan volume; obtaining contracts
with customers that have high scan volumes which justify lower scan prices; and
continuing competitive pressure in the MRI service industry and cost containment
efforts by health care payors. Other revenue increased $13.4 million, or 288.5%
partly due to a $4.3 million increase in lithotripsy revenue associated with the
MTI acquisition, as well as a $4.3 million increase in contract management
service revenue as a result of the Company commencing these service arrangements
primarily in connection with the MCIC acquisition. The remainder of the increase
in other revenue was primarily due to an increase in nuclear medicine revenue.
 
    The Company operated 214 MRI systems at September 30, 1998 compared to 95
MRI systems at September 30, 1997. The increase was primarily a result of the
MTI acquisition and to a lesser degree the MCIC and MDI acquisitions.
 
    Operating expenses, excluding depreciation, totaled $66.8 million in the
first nine months of 1998, an increase of $39.3 million, or 143.0% from the
first nine months of 1997. Payroll and related employee expenses increased $15.3
million, or 132.4%, primarily as a result of acquisitions, an increase in
operating staffing levels necessary to support new units in operation and
increased scans per unit. Preventative maintenance and cryogen expense increased
$5.6 million, or 83.1%, due to an increase in the number of systems in service
and the expiration of warranties on an increased number of MRI systems.
Equipment rental expense increased $5.9 million, or 358.3%, resulting from a
higher number of leased MRI systems in operation and the Company's leasing of 25
new tractors during the third quarter of 1997. Medical supplies expense
increased $1.8 million, or 344.8%, primarily as a result of the increased level
of nuclear medicine operations. Expenses associated with contract management
services increased $2.7 million as a result of the Company commencing these
service arrangements primarily in connection with the MCIC acquisition.
 
    Depreciation expense during the first nine months of 1998 totaled $18.9
million, an increase of $7.7 million, or 68.5% from the 1997 level principally
due to a higher amount of depreciable assets associated with equipment additions
and upgrades and equipment acquired through acquisitions. Amortization expense
during the first nine months of 1998 increased $3.0 million, or 168.5%, over the
1997 period as a result of the acquisitions made after the first nine months of
1997.
 
    Selling, general and administrative expenses totaled $12.9 million in the
first nine months of 1998, an increase of $6.6 million or 106.0%, from the same
period in 1997. Payroll and related expenses increased $3.4 million, or 94.2%,
primarily as a result of increased employee compensation related to increased
staffing levels necessary to support the Company's increased level of
operations. Bad debt expense increased $2.1 million primarily as a result of the
growth in revenues and the application of Alliance's more conservative bad debt
reserve policy to the acquired MTI and MDI operations.
 
    The transaction related costs primarily represent a special non-recurring
bonus paid in connection with the MTI acquisition and internal-use software
development costs associated with accounting and billing systems conversions of
the acquired companies.
 
    Interest expense of $25.1 million in the first nine months of 1998 was $19.8
million, or 373.0%, higher than 1997, as a result of higher average outstanding
debt balances during 1998 as compared to 1997. This increase was primarily
related to debt incurred in connection with the Recapitalization Merger and the
MTI and MDI acquisitions.
 
                                       12
<PAGE>
    An income tax provision of $4.5 million was recorded in the first nine
months of 1998. The effective tax rate increased to 51.2% in 1998 from 34.0% in
1997 primarily as a result of an increase in non-deductible goodwill
amortization expense.
 
    The Company's income before extraordinary loss was $4.3 million in the first
nine months of 1998 compared to income before extraordinary gain of $6.8 million
in the first nine months of 1997, a decrease of $2.5 million, primarily
attributable to increased interest, depreciation, and amortization costs and
transaction related costs. The Company reported an extraordinary loss of $2.3
million, net of income tax benefit, on early extinguishment of debt in the first
nine months of 1998. The Company reported an extraordinary gain, net of income
taxes, in the first nine months of 1997 of $1.3 million, on early extinguishment
of debt. The earnings per common share calculations reflect preferred dividend
requirements and financing fee accretion of $1.6 million in the first nine
months of 1998 and none in the first nine months of 1997.
 
    QUARTER ENDED SEPTEMBER 30, 1998 COMPARED TO QUARTER ENDED SEPTEMBER 30,
1997 -- Revenues for the third quarter of 1998 were $56.2 million, an increase
of $33.9 million, or 151.3%, over 1997, primarily due to the MTI and MDI
acquisitions. These acquisitions accounted for $24.0 million of the increase.
The remaining increase reflects higher scan-based MRI revenue, MRI revenue under
fixed fee contracts and other revenue items (including revenue for other
modalities). Overall, MRI revenue increased $28.2 million, as a result of a
139.7% increase in total scan volume partially offset by a 1.2% decrease in the
average revenue realized per MRI scan. The average daily scan volume per MRI
system increased 13.3% to 8.5 from 7.5 in the third quarter of 1997. Management
attributes the non-acquisition volume increase to the Company's continuing MRI
systems upgrade program, which has enabled the Company to obtain new, long-term
contracts from both existing and new customers, and to the continuing positive
effect of marketing programs implemented in early 1997. Management believes the
decrease in average revenue realized per scan is the result of many customers
achieving discount price levels in incremental scan volume; obtaining contracts
with customers that have high scan volumes which justify lower scan prices; and
continuing competitive pressure in the MRI service industry and cost containment
efforts by health care payors. Other revenue increased $5.6 million, or 322.4%
partly related to a $2.0 million increase in lithotripsy revenue associated with
the MTI acquisition, as well as a $1.7 million increase in contract management
service revenue as a result of the Company commencing these service arrangements
primarily in connection with the MCIC acquisition. The remainder of the increase
in other revenue was primarily due to an increase in nuclear medicine revenue.
 
    Operating expenses, excluding depreciation, totaled $27.1 million in the
third quarter of 1998, an increase of $17.4 million, or 179.8%, from the third
quarter of 1997. Payroll and related employee expenses increased $6.5 million,
or 152.9%, primarily as a result of acquisitions, an increase in operating
staffing levels necessary to support new units in operation and increased scans
per unit. Preventative maintenance and cryogen expense increased $1.1 million,
or 80.5%, due to an increase in the number of systems in service and the
expiration of warranties on an increased number of MRI systems. Equipment rental
expense increased $2.4 million, or 454.0%, resulting from a higher number of
leased MRI systems in operation. Medical supplies expense increased $0.9
million, or 474.5%, primarily as a result of the increased level of nuclear
medicine operations. Expenses associated with contract management services
increased $0.9 million as a result of the Company commencing these service
arrangements primarily in connection with the MCIC acquisition.
 
    Depreciation expense during the third quarter of 1998 totaled $7.2 million,
an increase of $3.1 million, or 77.1% from the 1997 level principally due to a
higher amount of depreciable assets associated with equipment additions and
upgrades and equipment acquired through acquisitions. Amortization expense
during the third quarter of 1998 increased $1.5 million, or 246.7%, over the
1997 period as a result of the acquisitions made after the third quarter of
1997.
 
                                       13
<PAGE>
    Selling, general and administrative expenses totaled $5.1 million in the
third quarter of 1998, an increase of $2.8 million or 124.6%, from the same
period in 1997. Payroll and related expenses increased $1.3 million, or 101.4%,
primarily as a result of increased employee compensation related to increased
staffing levels necessary to support the Company's increased level of
operations. Bad debt expense increased $1.1 million primarily as a result of the
growth in revenues and the application of Alliance's more conservative bad debt
reserve policy to the acquired MTI and MDI operations.
 
    The transaction related costs primarily represent internal-use software
development costs associated with accounting and billing systems conversions of
the acquired companies.
 
    Interest expense of $9.5 million in the third quarter of 1998 was $7.7
million, or 439.2%, higher than 1997, as a result of higher average outstanding
debt balances during 1998 as compared to 1997. This increase was primarily
related to debt incurred in connection with the Recapitalization Merger and the
MTI and MDI acquisitions.
 
    An income tax provision of $2.4 million was recorded in the third quarter of
1998. The effective tax rate increased to 50.6% in 1998 from 34.0% in 1997
primarily as a result of an increase in non-deductible goodwill amortization
expense.
 
    The Company's income before extraordinary loss was $2.4 million in the third
quarter of 1998 compared to income before extraordinary gain of $2.6 million in
the third quarter of 1997, a decrease of $0.2 million, primarily attributable to
increased interest, depreciation, and amortization costs. The Company reported
an extraordinary loss of $1.0 million, net of income tax benefit, on early
extinguishment of debt in the third quarter of 1998. The earnings per common
share calculations reflect preferred dividend requirements and financing fee
accretion of $0.6 million in the third quarter of 1998 and none in the third
quarter of 1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company generated $26.7 million and $22.1 million from operating
activities during the first nine months of 1998 and 1997, respectively. Capital
expenditures, consisting primarily of new equipment purchases, totaled $47.4
million and $34.2 million during the nine months ended September 30, 1998 and
1997, respectively. Since January 1, 1998, the Company has purchased 29 new MRI
systems, including replacement systems. The Company expects to purchase
additional equipment under binding commitments in 1998 and finance such
purchases with the Company's revolving loan facility.
 
    The Company's primary cash needs consist of capital expenditures and debt
service. The Company incurs capital expenditures for the purposes of (i)
providing routine upgrades of its MRI systems; (ii) replacing or making major
upgrades to older, less advanced systems with new state-of-the-art systems; and
(iii) purchasing new systems. The Company expects capital expenditures to be
approximately $65.0 million in 1998, which primarily reflects the anticipated
purchase of 39 new MRI systems, including replacement systems. The Company's
decision to purchase a new system is typically predicated on obtaining new or
extending existing customer contracts, which serve as the basis of demand for
the new system.
 
    As a result of the Recapitalization Merger, the Company issued $185.0
million of Notes (consisting of $140.0 million Senior Subordinated Notes due
2005, bearing interest at the rate of 9 5/8% per annum; and $45.0 million
Floating Interest Rate Subordinated Term Securities due 2005, bearing interest
at a rate per annum equal to LIBOR plus 4.19%) which are payable semiannually,
and require no principal repayments until maturity. The Company also entered
into a $125.0 million Credit Agreement consisting of a $50.0 million Term Loan
Facility ($50.0 million of which was funded at September 30, 1998) and a $75.0
million Revolving Loan Facility ($9.4 million of which was funded at September
30, 1998), and carried over approximately $12.7 million of other obligations.
The Term Loan matures on the sixth anniversary of the initial borrowing and
requires annual principal repayments of one percent per year during the first
five years and the outstanding principal amount in the sixth year. The Revolving
Loan Facility matures on the
 
                                       14
<PAGE>
fifth anniversary of the initial borrowing and has mandatory commitment
reductions of $37.5 million on the fourth and fifth anniversaries of the initial
borrowing. The Credit Agreement contains restrictive covenants, which, among
other things, limit the incurrence of additional indebtedness, dividends,
transactions with affiliates, asset sales, acquisitions, mergers and
consolidations, liens and encumbrances, and prepayments of other indebtedness.
In addition, the Credit Agreement requires loans to be prepaid with 100% of the
net proceeds of non-ordinary-course asset sales or other dispositions of
property, issuances of debt obligations and certain preferred stock and certain
insurance proceeds, 75% of annual excess cash flow and 50% of the net proceeds
from common equity and certain preferred stock issuances, in each case subject
to limited exceptions. Voluntary prepayments are permitted in whole or in part.
 
    Also as part of the Recapitalization Merger, the Company issued $15.0
million of Series F Preferred Stock. The Series F Preferred Stock pays dividends
at the rate of 13.5% per annum, payable quarterly in arrears, with such
dividends payable in kind for the first five years from the issue date and
thereafter in cash. The Series F Preferred Stock is mandatorily redeemable for
its liquidation preference plus accrued and unpaid dividends on the 10th
anniversary of the issue date. The Series F Preferred Stock is redeemable at the
option of the Company prior to the 10th anniversary at premiums (expressed as a
percentage of the accreted face value) declining over ten years from 13.5% to
0%. The Company does not currently intend to redeem the Series F Preferred Stock
prior to the mandatory redemption date.
 
    On November 21, 1997, the Company acquired Medical Consultants Imaging Co.
("MCIC"), a Cleveland, Ohio based provider of mobile MRI services, CT services
and other outsourced health care services. The acquisition also included MCIC's
one-half interest in a limited liability company in Michigan. The purchase price
consisted of $12.3 million cash plus the assumption of approximately $5.5
million in financing arrangements. MCIC operated 14 mobile MRI systems and
several other diagnostic imaging systems, primarily in Ohio, Michigan, Indiana
and Pennsylvania.
 
    On March 12, 1998, the Company acquired Mobile Technology Inc. ("MTI"),
another nationwide provider of diagnostic imaging services. The Company funded
the MTI acquisition with $20.0 million of existing Term Loan availability under
tranche A, $5.4 million of revolver borrowings, a $20.0 million increase to the
Term Loan Facility under tranche A, and a new $50.0 million Term Loan Facility
under tranche B. The Credit Agreement was amended to provide for the increased
Term Facilities.
 
    Also on March 12, 1998, the Company announced it had signed a definitive
agreement to acquire all of the equity interests in two operating subsidiaries
of American Shared Hospital Services ("American Shared"), which provide
diagnostic imaging services, for approximately $13.6 million in cash and
assumption of approximately $23.0 million of debt. On November 3, 1998, the
Company was notified that the U. S. Federal Trade Commission had concluded its
review regarding the Company's purchase of American Shared. No changes on the
terms of the transaction resulted from the review. The sale is now subject to
the approval of a majority of the shareholders of American Shared. American
Shared has scheduled a Special Meeting of Shareholders to be held on November
13, 1998 to consider approval of the sale. The sale is expected to close
promptly after the November 13 Shareholder Meeting.
 
    On May 19, 1998, the Company acquired Medical Diagnostics, Inc. ("MDI"), a
subsidiary of U. S. Diagnostic, Inc. The Company borrowed $30.0 million under
its revolving loan facility to finance the transaction.
 
    On September 24, 1998, the Company completed a $90.0 million expansion of
its Credit Agreement. The transaction added a new $85.0 million Term Loan
Facility under tranche C ($55.0 million of which was funded at September 30,
1998) and increased the Revolving Loan Facility to $80.0 million. The increased
Loan Facilities will provide funds to complete the American Shared acquisition
and also provide funds for future acquisitions and capital expenditures.
 
    The Company believes that subsequent to the Recapitalization Merger and
acquisitions previously mentioned and the incurrence of indebtedness related
thereto, based on current levels of operations and
 
                                       15
<PAGE>
anticipated growth, its cash from operations, together with other available
sources of liquidity, including borrowings available under the Revolving Loan
Facility, will be sufficient over the next several years to fund necessary
capital expenditures and make required payments of principal and interest on its
debt, including payments due on the Notes and obligations under the Credit
Agreement.
 
    The Company's expansion and acquisition strategy may require substantial
capital, and no assurance can be given that the Company will be able to raise
any necessary additional funds through bank financing or the issuance of equity
or debt securities on terms acceptable to the Company, if at all.
 
    Certain statements contained in Management's Discussion and Analysis of
Financial Condition and Results of Operations, particularly in the preceding

YEAR 2000
 
    The Company has assessed and continues to assess the impact of the Year 2000
Issue on its financial reporting systems and operations. The Year 2000 Issue is
the result of computer programs being written using two digits (rather than
four) to define the applicable year. Any of the Company's programs or equipment
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000 or not recognize the date at all, which could
result in system and/or equipment failures or system and/or equipment
miscalculations. During the nine months ended September 30, 1998, the Company
purchased new Year 2000 compatible financial reporting software which has now
been successfully implemented. The cost of this software was approximately $0.6
million, including installation. As a result, the Company does not believe that
its financial reporting capabilities will be adversely affected by the Year 2000
Issue. The Company is also developing a plan to modify other systems and
equipment applications. Based on preliminary information, costs of addressing
these items are currently not expected to have a material adverse impact on the
Company's financial position, results of operations or cash flows in future
periods. However, if the Company, its customers or vendors are unable to resolve
such processing issues in a timely manner, it could result in a material
financial risk. Accordingly, the Company plans to devote the necessary resources
to resolve all significant Year 2000 Issues in a timely manner.

         the proceeds of, and simultaneously with the incurrence of, the 
         respective incurrence of Revolving Loans) then outstanding, exceeds 
         an amount equal to the Total Revolving Loan Commitment then in 
         effect.

On and immediately after the occurrence of the Second Restatement Effective
Date, the Revolving Loan Commitment of each RL Bank shall be the amount set
forth opposite such RL Bank's name in Schedule I hereto directly below the
column entitled "Revolving Loan Commitment" (as same may be (x) reduced from
time to time pursuant to Sections 3.02, 3.03, 4.02 and/or 10 or (y) adjusted
from time to time as a result of assignments to or from such RL Bank pursuant to
Section 1.13 or 13.04(b)), such that the Total Revolving Loan Commitment (as of
the Second Restatement Effective Date) shall represent an increase of $5,000,000
over the Total Revolving Loan Commitment as in effect immediately before the
occurrence of the Second Restatement Effective Date. In connection with such
increase, the Borrower shall repay in full all Revolving Loans outstanding
immediately prior to the Second Restatement Effective Date (although Revolving
Loans may be incurred hereunder on the Second Restatement Effective Date in
accordance with the provisions hereof, so that the RL Banks participate in each
Borrowing of outstanding Revolving Loans PRO RATA on the basis of their
Revolving Loan Commitments (as in effect on the Second Restatement Effective
Date) as provided herein), it being understood and agreed that the Borrower
shall pay all breakage or similar costs of the type described in Section 1.11
incurred by the RL Banks in connection with any repayment or reborrowing of
Revolving Loans.

                  (c) Subject to and upon the terms and conditions herein set
forth, BTCo in its individual capacity agrees to make at any time and from time
to time on and after the Second Restatement Effective Date and prior to the
Swingline Expiry Date, a loan or loans to the Borrower (each, a "Swingline Loan"
and, collectively, the "Swingline Loans"), which Swingline Loans:

                    (i)    shall be denominated in U.S. Dollars;

                   (ii)    shall be made and maintained as Base Rate Loans;

                  (iii)    may be repaid and reborrowed in accordance with the
         provisions hereof;

                   (iv)    shall not exceed in aggregate principal amount at any
         time outstanding, 


                                     -3-

<PAGE>

         when combined with the aggregate principal amount of (x) all 
         Revolving Loans made by Non-Defaulting Banks then outstanding and 
         (y) the Letter of Credit Outstandings at such time, an amount equal 
         to the Adjusted Total Revolving Loan Commitment at such time (after 
         giving effect to any changes thereto on such date); and

                    (v)    shall not exceed in aggregate principal amount at any
         time outstanding the Maximum Swingline Amount.

BTCo shall not be obligated to make any Swingline Loans at a time when a Bank
Default exists unless BTCo has entered into arrangements satisfactory to it and
the Borrower to eliminate BTCo's risk with respect to the Defaulting Bank's or
Banks' participation in such Swingline Loans, including by cash collateralizing
such Defaulting Bank's or Banks' RL Percentage of the outstanding Swingline
Loans. BTCo will not make a Swingline Loan after it has received written notice
from the Borrower or the Required Banks stating that a Default or an Event of
Default exists until such time as BTCo shall have received a written notice of
(i) rescission of such notice from the party or parties originally delivering
the same or (ii) a waiver of such Default or Event of Default from the Required
Banks.

                  (d) On any Business Day, BTCo may, in its sole discretion,
give notice to the RL Banks that its outstanding Swingline Loans shall be funded
with a Borrowing of Revolving Loans (PROVIDED that each such notice shall be
deemed to have been automatically given upon the occurrence of a Default or an
Event of Default under Section 10.05 or upon the exercise of any of the remedies
provided in the last paragraph of Section 10), in which case a Borrowing of
Revolving Loans constituting Base Rate Loans (each such Borrowing, a "Mandatory
Borrowing") shall be made on the immediately succeeding Business Day by all RL
Banks PRO RATA based on each RL Bank's Adjusted RL Percentage, and the proceeds
thereof shall be applied directly to repay BTCo for such outstanding Swingline
Loans. Each RL Bank hereby irrevocably agrees to make Base Rate Loans upon one
Business Day's notice pursuant to each Mandatory Borrowing in the amount and in
the manner specified in the preceding sentence and on the date specified in
writing by BTCo notwithstanding (i) that the amount of the Mandatory Borrowing
may not comply with the Minimum Borrowing Amount otherwise required hereunder,
(ii) whether any conditions specified in Section 5 or 6 are then satisfied,
(iii) whether a Default or an Event of Default has occurred and is continuing,
(iv) the date of such Mandatory Borrowing and (v) the amount of the Total
Revolving Loan Commitment or the Adjusted Total Revolving Loan Commitment at
such time. In the event that any Mandatory Borrowing cannot for any reason be
made on the date otherwise required above (including, without limitation, as a
result of the commencement of a proceeding under the Bankruptcy Code in respect
of the Borrower), each RL Bank (other than BTCo) hereby agrees that it shall
forthwith purchase from BTCo (without recourse or warranty) such assignment of
the outstanding Swingline Loans as shall be necessary to cause the RL Banks to
share in such Swingline Loans ratably based upon their respective Adjusted 


                                     -4-

RL Percentages (determined before giving effect to any termination of the 
Revolving Loan Commitments pursuant to the last paragraph of Section 10), 
PROVIDED that (x) all interest payable on the Swingline Loans shall be for 
the account of BTCo until the date the respective assignment is purchased 
and, to the extent attributable to the purchased assignment, shall be payable 
to the RL Bank purchasing same from and after such date of purchase and (y) 
at the time any purchase of assignments pursuant to this sentence is actually 
made, the purchasing RL Bank shall be required to pay BTCo interest on the 
principal amount of assignment purchased for each day from and including the 
day upon which the Mandatory Borrowing would otherwise have occurred to but 
excluding the date of payment for such assignment, at the rate otherwise 
applicable to Revolving Loans maintained as Base Rate Loans hereunder for 
each day thereafter.

                  (e) Subject to and upon the terms and conditions set forth
herein, each Existing Tranche B Term Loan Bank severally agrees to continue, on
the Second Restatement Effective Date, the Existing Tranche B Term Loans made by
such Existing Tranche B Term Loan Bank to the Borrower pursuant to the First
Amended and Restated Credit Agreement and outstanding on the Second Restatement
Effective Date (immediately prior to giving effect thereto) (such Existing
Tranche B Term Loans continued as provided above, the "Tranche B Term Loans"),
which Tranche B Term Loans:

                    (i)    shall be denominated in U.S. Dollars;

                   (ii)    except as hereafter provided, shall, at the option of
         the Borrower, be continued and maintained as, and/or converted into,
         Base Rate Loans or Eurodollar Loans, PROVIDED that except as otherwise
         specifically provided in Section 1.10(b), all Tranche B Term Loans made
         as part of the same Borrowing shall at all times consist of Tranche B
         Term Loans of the same Type; and

                  (iii)    shall not exceed for any Existing Tranche B Term Loan
         Bank, in initial principal amount, that amount which equals the
         aggregate outstanding principal amount of the Existing Tranche B Term
         Loans, if any, made by such Existing Tranche B Term Loan Bank and
         outstanding on the Second Restatement Effective Date (immediately prior
         to giving effect thereto) as set forth on Schedule I hereto.

Once repaid, Tranche B Term Loans incurred hereunder may not be reborrowed.

                  (f) Subject to and upon the terms and conditions set forth
herein, each Bank with a Tranche C Term Loan Commitment severally agrees to make
a term loan or term loans (each, a "Tranche C Term Loan" and, collectively, the
"Tranche C Term Loans") to the Borrower, which Tranche C Term Loans:


                                     -5-

                    (i)    shall be incurred pursuant to one or more drawings, 
         with (x) the first such drawing to be made on the Second Restatement
         Effective Date for the purposes described in Section 7.05(a)(i), (y)
         the last such drawing to be made on the ASHS Acquisition Date for the
         purposes described in Section 7.05(a)(ii) and (z) any other such
         drawing to be made after the Second Restatement Effective Date and
         prior to the ASHS Acquisition Date for the purposes described in
         Section 7.05(a)(iii);

                   (ii)    shall be denominated in U.S. Dollars;

                  (iii)    except as hereafter provided, shall, at the option of
         the Borrower, be incurred and maintained as, and/or converted into,
         Base Rate Loans or Eurodollar Loans, PROVIDED that (x) except as
         otherwise specifically provided in Section 1.10(b), all Tranche C Term
         Loans made as part of the same Borrowing shall at all times consist of
         Tranche C Term Loans of the same Type and (y) unless the Agents have
         determined that the Syndication Date has occurred (at which time this
         clause (y) shall no longer be applicable), no more than three
         Borrowings of Tranche C Term Loans to be maintained as Eurodollar Loans
         may be incurred prior to the 90th day after the Second Restatement
         Effective Date (or, if later, the last day of the Interest Period
         applicable to the third Borrowing of Eurodollar Loans referred to
         below), each of which Borrowings of Eurodollar Loans may only have an
         Interest Period of one month, and the first of which Borrowings may
         only be made on, or within five Business Days after, the Second
         Restatement Effective Date, the second of which Borrowings may only be
         made on the last day of the Interest Period of the first such Borrowing
         and the third of which Borrowings may only be made on the last day of
         the Interest Period of the second such Borrowing;

                   (iv)    shall not exceed for any Bank, in initial principal
         amount for the Tranche C Term Loans being made by such Bank on the
         Second Restatement Effective Date, that amount which equals the lesser
         of (x) such Bank's C TL Percentage of $55,000,000 or (y) the Tranche C
         Term Loan Commitment of such Bank as in effect on the Second
         Restatement Effective Date (before giving effect to any reduction
         thereto on such date pursuant to Section 3.03(b)(i) but after giving
         effect to any reductions thereto on or prior to such date pursuant to
         Section 3.03(b)(iii)); and

                    (v)    shall not exceed for any Bank, in initial principal 
         amount for the Tranche C Term Loans being made by such Bank on any 
         Tranche C Term Loan Borrowing Date occurring after the Second 
         Restatement Effective Date, that amount which equals the Tranche C Term
         Loan Commitment of such Bank as in effect on such Tranche C Term Loan

         3.03(b)(iii)).

Once repaid, Tranche C Term Loans incurred hereunder may not be reborrowed.

                  1.02 MINIMUM BORROWING AMOUNTS, ETC. The aggregate principal
amount of each Borrowing of Loans under a respective Tranche shall not be less
than the Minimum Borrowing Amount applicable to such Tranche, PROVIDED that
Mandatory Borrowings shall be made in the amounts required by Section 1.01(d).
More than one Borrowing may be incurred on any day, PROVIDED that at no time
shall there be outstanding more than seven Borrowings of Eurodollar Loans.

                  1.03 NOTICE OF BORROWING. (a) Whenever the Borrower desires to
make a Borrowing hereunder (excluding Borrowings of Swingline Loans and
Mandatory Borrowings), it shall give the Administrative Agent at its Notice
Office, prior to 12:00 Noon (New York time), at least three Business Days' prior
written notice (or telephonic notice promptly confirmed in writing) of each
Borrowing of Eurodollar Loans and at least one Business Day's prior written
notice (or telephonic notice promptly confirmed in writing) of each Borrowing of
Base Rate Loans to be made hereunder. Each such notice (each, a "Notice of
Borrowing") shall, except as otherwise expressly provided in Section 1.10, be
irrevocable, and, in the case of each written notice and each confirmation of
telephonic notice, shall be in the form of Exhibit A, appropriately completed to
specify: (i) the aggregate principal amount of the Loans to be made pursuant to
such Borrowing, (ii) the date of such Borrowing (which shall be a Business Day),
(iii) whether the respective Borrowing shall consist of Tranche A Term Loans,
Tranche B Term Loans, Tranche C Term Loans or Revolving Loans, (iv) whether the
respective Borrowing shall consist of Base Rate Loans or, to the extent
permitted hereunder, Eurodollar Loans and, if Eurodollar Loans, the Interest
Period to be initially applicable thereto and (v) in the case of a Borrowing of
Revolving Loans the proceeds of which are to be utilized to finance, in whole or

the aggregate principal amount of such Revolving Loans to be utilized in
connection with such Permitted Acquisition and (z) the Total Unutilized
Revolving Loan Commitment then in effect after giving effect to the respective
Permitted Acquisition (and all payments to be made in connection therewith). The
Administrative Agent shall promptly give each Bank which is required to make
Loans of the Tranche specified in the respective Notice of Borrowing, written
notice (or telephonic notice promptly confirmed in writing) of each proposed
Borrowing, of such Bank's proportionate share thereof and of the other matters
required by the immediately preceding sentence to be specified in the Notice of
Borrowing.

                  (b) (i) Whenever the Borrower desires to incur Swingline Loans
hereunder, it shall give BTCo not later than 12:00 Noon (New York time) on the
day such Swingline Loan is to be made, written notice (or telephonic notice
promptly confirmed in writing) of each Swingline Loan to be made hereunder. Each
such notice shall be irrevocable and shall 


                                     -7-

<PAGE>

specify in each case (x) the date of such Borrowing (which shall be a 
Business Day) and (y) the aggregate principal amount of the Swingline Loan to 
be made pursuant to such Borrowing.

                  (ii) Mandatory Borrowings shall be made upon the notice

                  (c)  Without in any way limiting the obligation of the 
Borrower to confirm in writing any telephonic notice permitted to be given 
hereunder, the Administrative Agent or BTCo (in the case of a Borrowing of 
Swingline Loans) or the Letter of Credit Issuer (in the case of the issuance 
of Letters of Credit), as the case may be, may prior to receipt of written 
confirmation act without liability upon the basis of such telephonic notice, 
believed by the Administrative Agent, BTCo or the Letter of Credit Issuer, as 
the case may be, in good faith to be from an Authorized Officer of the 
Borrower. In each such case, the Administrative Agent's, BTCo's or the 
respective Letter of Credit Issuer's, as the case may be, record of the terms 
of such telephonic notice shall be conclusive evidence of the contents of 
such notice, absent manifest error.

                  1.04 DISBURSEMENT OF FUNDS. (a) Not later than 1:00 P.M. (New
York time) on the date specified in each Notice of Borrowing (or (x) in the case
of Swingline Loans, not later than 2:00 P.M. (New York time) on the date
specified in Section 1.03(b)(i) or (y) in the case of Mandatory Borrowings, not
later than 12:00 Noon (New York time) on the date specified in Section 1.01(d)),
each Bank with a Commitment of the respective Tranche will make available its
PRO RATA share (determined in accordance with Section 1.07), if any, of each
Borrowing requested to be made on such date (or in the case of Swingline Loans,
BTCo shall make available the full amount thereof) in the manner provided below.
All amounts shall be made available to the Administrative Agent in U.S. Dollars
and in immediately available funds at the Payment Office and the Administrative
Agent promptly will make available to the Borrower by depositing to its account
at the Payment Office the aggregate of the amounts so made available in the type
of funds received. Unless the Administrative Agent shall have been notified by
any Bank prior to the date of Borrowing that such Bank does not intend to make
available to the Administrative Agent its portion of the Borrowing or Borrowings
to be made on such date, the Administrative Agent may assume that such Bank has
made such amount available to the Administrative Agent on such date of
Borrowing, and the Administrative Agent, in reliance upon such assumption, may
(in its sole discretion and without any obligation to do so) make available to
the Borrower a corresponding amount. If such corresponding amount is not in fact
made available to the Administrative Agent by such Bank and the Administrative
Agent has made available same to the Borrower, the Administrative Agent shall be
entitled to recover such corresponding amount on demand from such Bank. If such
Bank does not pay such corresponding amount forthwith upon the Administrative
Agent's demand therefor, the Administrative Agent shall 


                                     -8-

<PAGE>

promptly notify the Borrower, and the Borrower shall immediately pay such
corresponding amount to the Administrative Agent. The Administrative Agent
shall also be entitled to recover on demand from such Bank or the Borrower,
as the case may be, interest on such corresponding amount in respect of each
day from the date such corresponding amount was made available by the
Administrative Agent to the Borrower to the date such corresponding amount is
recovered by the Administrative Agent, at a rate per annum equal to (x) if
paid by such Bank, the overnight Federal Funds Rate or (y) if paid by the
Borrower, the then applicable rate of interest, calculated in accordance with
Section 1.08.

                  (b) Nothing in this Agreement shall be deemed to relieve
any Bank from its obligation to fulfill its commitments hereunder or to
prejudice any rights which the Borrower may have against any Bank as a result
of any default by such Bank hereunder.

                  1.05 NOTES. (a) The Borrower's obligation to pay the

the Agents have determined that the Syndication Date has occurred (at which 
time this clause (iii) shall no longer be applicable), prior to the 90th day 
after the Second Restatement Effective Date, Tranche C Term Loans maintained 
as Base Rate Loans may not be converted into Eurodollar Loans unless any such 
conversion is effective on the first day of the first, second or third 
Interest Period referred to in clause (y) of Section 1.01(f)(iii) and so long 
as such conversion does not result in a greater number of Borrowings of 
Eurodollar Loans prior to the 90th day after the Second Restatement Effective 

                                     -11-
<PAGE>

Date as are permitted under Section 1.01(f)(iii) and (iv) Borrowings of 
Eurodollar Loans resulting from this Section 1.06 shall be limited in number 
as provided in Section 1.02. Each such conversion shall be effected by the 
Borrower by giving the Administrative Agent at its Notice Office, prior to 
11:00 A.M. (New York time), at least three Business Days' (or one Business 
Day's in the case of a conversion into Base Rate Loans) prior written notice 
(or telephonic notice promptly confirmed in writing) (each, a "Notice of 
Conversion") specifying the Loans to be so converted, the Borrowing(s) 
pursuant to which the Loans were made and, if to be converted into a 
Borrowing of Eurodollar Loans, the Interest Period to be initially applicable 
thereto. The Administrative Agent shall give each Bank prompt notice of any 
such proposed conversion affecting any of its Loans. Upon any such 
conversion, the proceeds thereof will be deemed to be applied directly on the 
day of such conversion to prepay the outstanding principal amount of the 
Loans being converted.

                  1.07 PRO RATA BORROWINGS. All Borrowings of Tranche A Term
Loans, Tranche B Term Loans, Tranche C Term Loans and Revolving Loans under
this Agreement shall be incurred by the Borrower from the Banks PRO RATA on
the basis of such Banks' Tranche A Term Loan Borrowing Amounts, Tranche B
Term Loan Borrowing Amounts, Tranche C Term Loan Commitments or Revolving
Loan Commitments, as the case may be; PROVIDED that all Borrowings of
Revolving Loans made pursuant to a Mandatory Borrowing shall be incurred from
the RL Banks PRO RATA on the basis on their Adjusted RL Percentages. It is
understood that no Bank shall be responsible for any default by any other
Bank of its obligation to make Loans hereunder and that each Bank shall be
obligated to make the Loans to be made by it hereunder, regardless of the
failure of any other Bank to fulfill its commitments hereunder.

                  1.08 INTEREST. (a) The unpaid principal amount of each Base
Rate Loan shall bear interest from the date of the Borrowing thereof until
the earlier of (i) the maturity (whether by acceleration or otherwise) of
such Base Rate Loan and (ii) the conversion of such Base Rate Loan to a
Eurodollar Loan pursuant to Section 1.06, at a rate per annum which shall at
all times be the relevant Applicable Margin PLUS the Base Rate in effect from
time to time.

                  (b) The unpaid principal amount of each Eurodollar Loan
shall bear interest from the date of the Borrowing thereof until the earlier
of (i) the maturity (whether by acceleration or otherwise) of such Eurodollar
Loan and (ii) the conversion of such Eurodollar Loan to a Base Rate Loan
pursuant to Section 1.06, 1.09 or 1.10(b), as applicable, at a rate per annum
which shall at all times be the relevant Applicable Margin plus the
Eurodollar Rate for such Interest Period.

                  (c) Overdue principal and, to the extent permitted by law,
overdue interest in respect of each Loan shall bear interest at a rate per
annum equal to the greater of (x) the rate which is 2% in excess of the rate
borne by the respective such Loans immediately prior

                                     -12-
<PAGE>

to the respective payment default and (y) the rate which is 2% in excess of
the rate otherwise applicable to Base Rate Loans from time to time. Interest
which accrues under this Section 1.08(c) shall be payable on demand.

                  (d) Interest shall accrue from and including the date of
any Borrowing to but excluding the date of any repayment thereof and shall be
payable (i) in respect of each Base Rate Loan, quarterly in arrears on each
Quarterly Payment Date, (ii) in respect of each Eurodollar Loan, on (x) the
date of any conversion into a Base Rate Loan pursuant to Section 1.06, 1.09
or 1.10(b), as applicable (on the amount converted) and (y) the last day of
each Interest Period applicable thereto and, in the case of an Interest
Period in excess of three months, on each date occurring at three month
intervals after the first day of such Interest Period and (iii) in respect of
each Loan, on (x) the date of any prepayment or repayment thereof (on the
amount prepaid or repaid), (y) at maturity (whether by acceleration or
otherwise) and (z) after such maturity, on demand.

                  (e) All computations of interest hereunder shall be made in
accordance with Section 13.07(b).

                  (f) Upon each Interest Determination Date, the
Administrative Agent shall determine the Eurodollar Rate for the respective
Interest Period or Interest Periods and shall promptly notify the Borrower
and the Banks thereof. Each such determination shall, absent manifest error,
be final and conclusive and binding on all parties hereto.

                  1.09 INTEREST PERIODS. At the time the Borrower gives a
Notice of Borrowing or Notice of Conversion in respect of the making of, or
conversion into, a Borrowing of Eurodollar Loans (in the case of the initial
Interest Period applicable thereto) or prior to 11:00 A.M. (New York time) on
the third Business Day prior to the expiration of an Interest Period
applicable to a Borrowing of Eurodollar Loans (in the case of any subsequent
Interest Period), the Borrower shall have the right to elect by giving the
Administrative Agent written notice (or telephonic notice promptly confirmed
in writing) of the Interest Period applicable to such Borrowing, which
Interest Period shall, at the option of the Borrower (but otherwise subject
to clause (y) of the proviso to Section 1.01(f)(iii) and clause (iii) of the
proviso to Section 1.06), be a one, two, three or six month period.
Notwithstanding anything to the contrary contained above:

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

                   (ii) the initial Interest Period for any Borrowing of
         Eurodollar Loans shall commence on the date of such Borrowing
         (including the date of any conversion from a Borrowing of Base Rate
         Loans) and each Interest Period occurring thereafter in respect of
         such Borrowing shall commence on the day on which the next preced-

                                     -13-
<PAGE>

         ing Interest Period applicable thereto expires;

                  (iii) if any Interest Period for any Borrowing of
         Eurodollar Loans begins on a day for which there is no numerically
         corresponding day in the calendar month at the end of such Interest
         Period, such Interest Period shall end on the last Business Day of
         such calendar month;

                   (iv) if any Interest Period would otherwise expire on a
         day which is not a Business Day, such Interest Period shall expire
         on the next succeeding Business Day, PROVIDED that if any Interest
         Period for any Borrowing of Eurodollar Loans would otherwise expire
         on a day which is not a Business Day but is a day of the month after
         which no further Business Day occurs in such month, such Interest
         Period shall expire on the next preceding Business Day;

                    (v) no Interest Period for a Borrowing under a Tranche
         shall be selected which would extend beyond the respective Maturity
         Date for such Tranche;

                   (vi) no Interest Period may be elected at any time when a
         Default or an Event of Default is then in existence;

                  (vii) no Interest Period in respect of any Borrowing of
         Revolving Loans shall be elected which extends beyond any date upon
         which a Scheduled Commitment Reduction will be required to be made
         under Section 3.03(c) if the aggregate principal amount of such
         Revolving Loans which have Interest Periods which will expire after
         such date, when added to the Stated Amount of all Letters of Credit
         which by their terms expire after such date, will be in excess of
         the Total Revolving Loan Commitment as the same will be in effect
         after giving effect to the respective Scheduled Commitment
         Reduction; and

                 (viii) no Interest Period in respect of any Borrowing of
         Tranche A Term Loans, Tranche B Term Loans or Tranche C Term Loans
         shall be elected which extends beyond any date upon which a
         Scheduled Repayment of such Tranche of Term Loans will be required
         to be made under Section 4.02(b) if, after giving effect to the
         election of such Interest Period, the aggregate principal amount of
         such Tranche A Term Loans, Tranche B Term Loans or Tranche C Term
         Loans, as the case may be, which have Interest Periods which will
         expire after such date will be in excess of the aggregate principal
         amount of such Tranche A Term Loans, Tranche B Term Loans or Tranche
         C Term Loans, as the case may be, then outstanding less the
         aggregate amount of such required Scheduled Repayment.

                  If upon the expiration of any Interest Period applicable to a
Borrowing of Eurodollar Loans, the Borrower has failed to elect, or is not
permitted to elect, a new

                                     -14-
<PAGE>


Interest Period to be applicable to the respective Borrowing of Eurodollar
Loans as provided above, the Borrower shall be deemed to have elected to
convert such Borrowing into a Borrowing of Base Rate Loans effective as of
the expiration date of such current Interest Period.

                  1.10 INCREASED COSTS; ILLEGALITY; ETC. (a) In the event
that (x) in the case of clause (i) below, the Administrative Agent or (y) in
the case of clauses (ii) and (iii) below, any Bank, shall have determined
(which determination shall, absent manifest error, be final and conclusive
and binding upon all parties hereto):

                    (i) on any Interest Determination Date, that, by reason
         of any changes arising after the Second Restatement Effective Date
         affecting the interbank Eurodollar market, adequate and fair means
         do not exist for ascertaining the applicable interest rate on the
         basis provided for in the definition of Eurodollar Rate; or

                   (ii) at any time, that such Bank shall incur increased
         costs or reductions in the amounts received or receivable hereunder
         with respect to any Eurodollar Loans because of (x) any change since
         the Second Restatement Effective Date in any applicable law,
         governmental rule, regulation, guideline, order or request (whether
         or not having the force of law), or in the interpretation or
         administration thereof and including the introduction of any new law
         or governmental rule, regulation, guideline, order or request, such
         as, for example, but not limited to, (A) a change in the basis of
         taxation of payment to any Bank of the principal of or interest on
         such Eurodollar Loans or any other amounts payable hereunder (except
         for changes with respect to any tax imposed on, or determined by
         reference to, the net income, net profits or capital (including
         branch profits tax) of such Bank or any franchise tax based on the
         net income or net profits of such Bank pursuant to the laws of the
         jurisdiction in which such Bank is organized, or in which such
         Bank's principal office or applicable lending office is located or
         any subdivision thereof or therein), or (B) a change in official
         reserve requirements, but, in all events, excluding reserves
         required under Regulation D to the extent included in the
         computation of the Eurodollar Rate and/or (y) other circumstances
         affecting such Bank, the interbank Eurodollar market or the position
         of such Bank in such market; or

                  (iii) at any time since the Second Restatement Effective Date,
         that the making or continuance of any Eurodollar Loan has become
         unlawful by compliance by such Bank with any law, governmental rule,
         regulation, guideline or order (or would conflict with any governmental
         rule, regulation, guideline, request or order not having the force of
         law but with which such Bank customarily complies even though the
         failure to comply therewith would not be unlawful), or has become
         impracticable as a result of a contingency occurring after the Second
         Restatement

                                     -15-
<PAGE>

         Effective Date which materially and adversely affects the interbank
         Eurodollar market;

then, and in any such event, such Bank (or the Administrative Agent in the
case of clause (i) above) shall promptly give notice (by telephone confirmed
in writing) to the Borrower and (except in the case of clause (i)) to the
Administrative Agent of such determination (which notice the Administrative
Agent shall promptly transmit to each of the other Banks). Thereafter, (x) in
the case of clause (i) above, Eurodollar Loans shall no longer be available
until such time as the Administrative Agent notifies the Borrower and the
Banks that the circumstances giving rise to such notice by the Administrative
Agent no longer exist, and any Notice of Borrowing or Notice of Conversion
given by the Borrower with respect to Eurodollar Loans which have not yet
been incurred (including by way of conversion) shall be deemed rescinded by
the Borrower, (y) in the case of clause (ii) above, the Borrower agrees,
subject to the provisions of Section 13.18 (to the extent applicable), to pay
to such Bank, upon written demand therefor, such additional amounts (in the
form of an increased rate of, or a different method of calculating, interest
or otherwise as such Bank in its sole discretion shall determine) as shall be
required to compensate such Bank for such increased costs or reductions in
amounts received or receivable hereunder but without duplication of any
payments due under Section 4.04 (a written notice as to the additional
amounts owed to such Bank, showing in reasonable detail the basis for the
calculation thereof, submitted to the Borrower by such Bank shall, absent
manifest error, be final and conclusive and binding upon all parties hereto,
although the failure to give any such notice shall not release or diminish
any of the Borrower's obligations to pay additional amounts pursuant to this
Section 1.10(a) upon the subsequent receipt of such notice) and (z) in the
case of clause (iii) above, the Borrower shall take one of the actions
specified in Section 1.10(b) as promptly as possible and, in any event,
within the time period required by law.

                  (b) At any time that any Eurodollar Loan is affected by the
circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may
(and in the case of a Eurodollar Loan affected pursuant to Section
1.10(a)(iii), the Borrower shall) either (i) if the affected Eurodollar Loan
is then being made pursuant to a Borrowing, cancel said Borrowing by giving
the Administrative Agent telephonic notice (confirmed promptly in writing)
thereof on the same date that the Borrower was notified by a Bank pursuant to
Section 1.10(a)(ii) or (iii)), or (ii) if the affected Eurodollar Loan is
then outstanding, upon at least three Business Days' notice to the
Administrative Agent, require the affected Bank to convert each such
Eurodollar Loan into a Base Rate Loan (which conversion, in the case of the
circumstance described in Section 1.10(a)(iii), shall occur no later than the
last day of the Interest Period then applicable to such Eurodollar Loan or
such earlier day as shall be required by applicable law); PROVIDED that if
more than one Bank is affected at any time, then all affected Banks must be
treated the same pursuant to this Section 1.10(b).

                  (c) If any Bank shall have determined that after the Second
Restatement

                                     -16-

Effective Date, the adoption or effectiveness of any applicable law, rule or
regulation regarding capital adequacy, or any change therein, or any change
in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation
or administration thereof, or compliance by such Bank or any corporation
controlling such Bank with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing
the rate of return on such Bank's or such other corporation's capital or
assets as a consequence of such Bank's Commitment or Commitments hereunder or
its obligations hereunder to a level below that which such Bank or such other
corporation could have achieved but for such adoption, effectiveness, change
or compliance (taking into consideration such Bank's or such other
corporation's policies with respect to capital adequacy), then from time to
time, upon written demand by such Bank (with a copy to the Administrative
Agent), accompanied by the notice referred to in the last sentence of this
clause (c), the Borrower agrees, subject to the provisions of Section 13.18
(to the extent applicable), to pay to such Bank such additional amount or
amounts as will compensate such Bank or such other corporation for such
reduction in the rate of return to such Bank or such other corporation. Each
Bank, upon determining in good faith that any additional amounts will be
payable pursuant to this Section 1.10(c), will give prompt written notice
thereof to the Borrower (a copy of which shall be sent by such Bank to the
Administrative Agent), which notice shall set forth in reasonable detail the
basis of the calculation of such additional amounts, although the failure to
give any such notice shall not release or diminish the Borrower's obligations
to pay additional amounts pursuant to this Section 1.10(c) upon the
subsequent receipt of such notice. A Bank's reasonable good faith
determination of compensation owing under this Section 1.10(c) shall, absent
manifest error, be final and conclusive and binding on all the parties hereto.

                  1.11 COMPENSATION. The Borrower agrees, subject to the
provisions of Section 13.18 (to the extent applicable), to compensate each Bank,
promptly upon its written request (which request shall set forth in reasonable
detail the basis for requesting such compensation), for all losses, expenses and
liabilities (including, without limitation, any loss, expense or liability
incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Bank to fund its Eurodollar Loans) which such Bank may sustain:
(i) if for any reason (other than a default by such Bank or any Agent) a
Borrowing of, or conversion from or into, Eurodollar Loans does not occur on a
date specified therefor in a Notice of Borrowing or Notice of Conversion given
by the Borrower (whether or not withdrawn by the Borrower or deemed withdrawn
pursuant to Section 1.10(a)); (ii) if any repayment (including any repayment
made pursuant to Section 4.01 or 4.02 or as a result of an acceleration of the
Loans pursuant to Section 10 or as a result of the replacement of a Bank
pursuant to Section 1.13 or 13.12(b)) or conversion of any Eurodollar Loans of
the Borrower occurs on a date which is not the last day of an Interest Period
applicable thereto; (iii) if any prepayment of any Eurodollar Loans is not made
on any date specified in a notice of prepayment given by the Borrower; or (iv)
as a consequence of (x) any other default by

                                     -17-
<PAGE>

the Borrower to repay its Eurodollar Loans when required by the terms of this
Agreement or (y) an election made by the Borrower pursuant to Section
1.10(b). Each Bank's calculation of the amount of compensation owing pursuant
to this Section 1.11 shall be made in good faith. A Bank's basis for
requesting compensation pursuant to this Section 1.11 and a Bank's
calculation of the amount thereof, shall, absent manifest error, be final and
conclusive and binding on all parties hereto.

                  1.12 CHANGE OF LENDING OFFICE. Each Bank agrees that, upon
the occurrence of any event giving rise to the operation of Section
1.10(a)(ii) or (iii), 1.10(c), 2.05 or 4.04 with respect to such Bank, it
will, if requested by the Borrower, use reasonable efforts (subject to
overall policy considerations of such Bank) to designate another lending
office for any Loans or Letters of Credit affected by such event; PROVIDED
that such designation is made on such terms that, in the sole judgment of
such Bank, such Bank and its lending office suffer no economic, legal or
regulatory disadvantage, with the object of avoiding the consequences of the
event giving rise to the operation of any such Section. Nothing in this
Section 1.12 shall affect or postpone any of the obligations of the Borrower
or the right of any Bank provided in Section 1.10, 2.05 or 4.04.

                  1.13 REPLACEMENT OF BANKS. (x) If any Bank becomes a
Defaulting Bank, (y) upon the occurrence of any event giving rise to the
operation of Section 1.10(a)(ii) or (iii), Section 1.10(c), Section 2.05 or
Section 4.04 with respect to any Bank which results in such Bank charging to
the Borrower increased costs in a material amount in excess of those being
generally charged by the other Banks or (z) in the case of a refusal by a
Bank to consent to a proposed change, waiver, discharge or termination with
respect to this Agreement which has been approved by the Required Banks as
provided in Section 13.12(b), the Borrower shall have the right, in
accordance with Section 13.04(b), if no Default or Event of Default then
exists or would exist after giving effect to such replacement, to replace
such Bank (the "Replaced Bank") with one or more other Eligible Transferee or
Transferees, none of whom shall constitute a Defaulting Bank at the time of
such replacement (collectively, the "Replacement Bank") and each of whom
shall be reasonably acceptable to the Administrative Agent or, at the option
of the Borrower, to replace only (a) the Revolving Loan Commitment (and
outstandings pursuant thereto) of the Replaced Bank with an identical
Revolving Loan Commitment provided by the Replacement Bank or (b) in the case
of a replacement as provided in Section 13.12(b) where the consent of the
respective Bank is required with respect to less than all Tranches of its
Loans or Commitments, the Commitments and/or outstanding Loans of such Bank
in respect of each Tranche where the consent of such Bank would otherwise be
individually required, with identical Commitments and/or Loans of the
respective Tranche provided by the Replacement Bank; PROVIDED that:

                    (i) at the time of any replacement pursuant to this Section
         1.13, the Replacement Bank shall enter into one or more Assignment and
         Assumption

         pursuant to said Section 13.04(b) to be paid by the Replacement
         Bank) pursuant to which the Replacement Bank shall acquire all of
         the Commitments and outstanding Loans (or, in the case of the
         replacement of only (a) the Revolving Loan Commitment, the Revolving
         Loan Commitment and outstanding Revolving Loans and participations

         Loans and Term Loan Commitment of any Tranche, the outstanding Term
         Loans and Term Loan Commitment of the respective Tranche or
         Tranches) of, and in each case (except for the replacement of only
         the outstanding Term Loans and Term Loan Commitment of any or all
         Tranches of Term Loans of the respective Bank) participations in
         Letters of Credit by, the Replaced Bank and, in connection
         therewith, shall pay to (x) the Replaced Bank in respect thereof an
         amount equal to the sum of (A) an amount equal to the principal of,
         and all accrued interest on, all outstanding Loans (or of the Loans
         of the respective Tranche or Tranches being replaced) of the
         Replaced Bank, (B) an amount equal to all Unpaid Drawings (unless
         there are no Unpaid Drawings with respect to the Tranche being
         replaced) that have been funded by (and not reimbursed to) such
         Replaced Bank, together with all then unpaid interest with respect
         thereto at such time and (C) an amount equal to all accrued, but
         theretofore unpaid, Fees owing to the Replaced Bank (but only with
         respect to the relevant Tranche, in the case of the replacement of
         less than all Tranches of Loans then held by the respective Replaced
         Bank) pursuant to Section 3.01, (y) except in the case of the
         replacement of only the outstanding Term Loans and Term Loan
         Commitment of any or all Tranches of Term Loans of a Replaced Bank,

         Adjusted RL Percentage of any Unpaid Drawing relating to Letters of
         Credit issued by such Letter of Credit Issuer (which at such time
         remains an Unpaid Drawing) to the extent such amount was not
         theretofore funded by such Replaced Bank and (z) in the case of any
         replacement of Revolving Loan Commitments, BTCo an amount equal to
         such Replaced Bank's Adjusted RL Percentage of any Mandatory
         Borrowing to the extent such amount was not theretofore funded by
         such Replaced Bank; and

                   (ii) all obligations of the Borrower then owing to the
         Replaced Bank (other than those (a) specifically described in clause
         (i) above in respect of which the assignment purchase price has
         been, or is concurrently being, paid, but including all amounts, if
         any, owing under Section 1.11 or (b) relating to any Tranche of
         Loans and/or Commitments of the respective Replaced Bank which will
         remain outstanding after giving effect to the respective

Commitment hereunder, the Replaced Bank shall cease to constitute a Bank
hereunder, except with respect to indemnification provisions under this
Agreement (including, without limitation, Sections 1.10, 1.11, 2.05, 4.04,
13.01 and 13.06), which shall survive as to such Replaced Bank and (y) except
in the case of the replacement of only outstanding Term Loans and Term Loan
Commitments, the Adjusted RL Percentages of the Banks shall be automatically

                  SECTION 2.  LETTERS OF CREDIT.

                  2.01 LETTERS OF CREDIT. (a) Subject to and upon the terms
and conditions herein set forth, the Borrower may request a Letter of Credit
Issuer at any time and from time to time on or after the Second Restatement
Effective Date and prior to the tenth Business Day (or the 30th day in the
case of Trade Letters of Credit) preceding the Revolving Loan Maturity Date
to issue, (x) for the account of the Borrower and for the benefit of any
holder (or any trustee, agent or other similar representative for any such
holders) of L/C Supportable Indebtedness, irrevocable sight standby letters
of credit in a form customarily used by such Letter of Credit Issuer or in
such other form as has been approved by such Letter of Credit Issuer (each
such standby letter of credit, a "Standby Letter of Credit") in support of
such L/C Supportable Indebtedness and (y) for the account of the Borrower and
for the benefit of sellers of goods to the Borrower or any Subsidiary
Guarantor in the ordinary course of business, irrevocable sight trade letters
of credit in a form customarily used by such Letter of Credit Issuer or in
such other form as has been approved by such Letter of Credit Issuer (each
such trade letter of credit, a "Trade Letter of Credit", and each such
Standby Letter of Credit and Trade Letter of Credit, a "Letter of Credit"
and, collectively, the "Letters of Credit").

                  (b) Subject to and upon the terms and conditions set forth
herein, each Letter of Credit Issuer hereby agrees that it will, at any time
and from time to time on and after the Second Restatement Effective Date and
prior to the tenth Business Day (or the 30th day in the case of Trade Letters
of Credit) preceding the Revolving Loan Maturity Date, following its receipt
of the respective Letter of Credit Request, issue for the account of the
Borrower one or more Letters of Credit, (x) in the case of Trade Letters of
Credit, in support of trade obligations of the Borrower or any Subsidiary
Guarantor that arise in the ordinary course of business or (y) in the case of
Standby Letters of Credit, in support of such L/C Supportable Indebtedness as
is permitted to remain outstanding hereunder. Notwithstanding the foregoing,
no Letter of Credit Issuer shall be under any obligation to issue any Letter
of Credit if at the time of such issuance:

                                     -20-
<PAGE>


                    (i) any order, judgment or decree of any governmental
         authority or arbitrator shall purport by its terms to enjoin or
         restrain such Letter of Credit Issuer from issuing such Letter of
         Credit or any requirement of law applicable to such Letter of Credit
         Issuer or any request or directive (whether or not having the force of
         law) from any governmental authority with jurisdiction over such Letter
         of Credit Issuer shall prohibit, or request that such Letter of Credit
         Issuer refrain from, the issuance of letters of credit generally or
         such Letter of Credit in particular or shall impose upon such Letter of
         Credit Issuer with respect to such Letter of Credit any restriction or
         reserve or capital requirement (for which such Letter of Credit Issuer
         is not otherwise compensated) not in effect on the date hereof, or any
         unreimbursed loss, cost or expense which was not applicable, in effect
         or known to such Letter of Credit Issuer as of the date hereof and
         which such Letter of Credit Issuer in good faith deems material to it;
         or

                   (ii) such Letter of Credit Issuer shall have received written
         notice from the Borrower or the Required Banks prior to the issuance of
         such Letter of Credit of the type described in clause (vi) of Section
         2.01(c) or the last sentence of Section 2.02(b).

                  (c) Notwithstanding the foregoing, (i) no Letter of Credit
shall be issued the Stated Amount of which, when added to the Letter of
Credit Outstandings (exclusive of Unpaid Drawings which are repaid on the
date of, and prior to the issuance of, the respective Letter of Credit) at
such time, would exceed either (x) $15,000,000 or (y) when added to the
aggregate principal amount of all Revolving Loans made by the Non-Defaulting
Banks and then outstanding and all Swingline Loans then outstanding, the
Adjusted Total Revolving Loan Commitment at such time; (ii) (x) each Standby
Letter of Credit shall have an expiry date occurring not later than one year
after such Standby Letter of Credit's date of issuance, PROVIDED that any
such Standby Letter of Credit may be extendable for successive periods of up
to one year, but not beyond the tenth Business Day preceding the Revolving
Loan Maturity Date, on terms acceptable to the Letter of Credit Issuer and
(y) each Trade Letter of Credit shall have an expiry date occurring not later
than 180 days after such Trade Letter of Credit's date of issuance; (iii) (x)
no Standby Letter of Credit shall have an expiry date occurring later than
the tenth Business Day preceding the Revolving Loan Maturity Date and (y) no
Trade Letter of Credit shall have an expiry date occurring later than 30 days
prior to the Revolving Loan Maturity Date; (iv) each Letter of Credit shall
be denominated in U.S. Dollars; (v) the Stated Amount of each Letter of
Credit shall not be less than $100,000 or such lesser amount as is acceptable
to the respective Letter of Credit Issuer; and (vi) no Letter of Credit
Issuer will issue any Letter of Credit after it has received written notice
from the Borrower or the Required Banks stating that a Default or an Event of
Default exists until such time as such Letter of Credit Issuer shall have
received a written notice of (x) rescission of such notice from the party or
parties originally delivering the same or (y) a waiver of such Default or
Event of Default by the Required Banks.

                                     -21-
<PAGE>

                  (d) Notwithstanding the foregoing, in the event a Bank
Default exists, no Letter of Credit Issuer shall be required to issue any
Letter of Credit unless the respective Letter of Credit Issuer has entered
into arrangements satisfactory to it and the Borrower to eliminate such
Letter of Credit Issuer's risk with respect to the participation in Letters
of Credit of the Defaulting Bank or Banks, including by cash collateralizing
such Defaulting Bank's or Banks' Adjusted RL Percentage of the Letter of
Credit Outstandings, as the case may be.

                  (e) Schedule XI hereto contains a description of all
letters of credit issued pursuant to the First Amended and Restated Credit
Agreement and outstanding on the Second Restatement Effective Date. Each such
letter of credit, including any extension or renewal thereof (each, as
amended from time to time in accordance with the terms hereof and thereof, an
"Existing Letter of Credit") shall constitute a "Letter of Credit" for all
purposes of this Agreement, issued, for purposes of Section 2.03(a), on the
Second Restatement Effective Date. In addition, each letter of credit
designated as a "Standby Letter of Credit" or "Trade Letter of Credit" on
Schedule XI shall constitute a "Standby Letter of Credit" or "Trade Letter of
Credit", as the case may be, for all purposes of this Agreement. Any Bank
hereunder to the extent it has issued an Existing Letter of Credit shall
constitute the "Letter of Credit Issuer" with respect to such Letter of
Credit for all purposes of this Agreement.

                  2.02 LETTER OF CREDIT REQUESTS. (a) Whenever the Borrower
desires that a Letter of Credit be issued, the Borrower shall give the
Administrative Agent and the respective Letter of Credit Issuer written
notice thereof prior to 12:00 Noon (New York time) at least five Business
Days (or such shorter period as may be acceptable to the respective Letter of
Credit Issuer) prior to the proposed date of issuance (which shall be a
Business Day) which written notice shall be in the form of Exhibit C (each, a
"Letter of Credit Request"). Each Letter of Credit Request shall include any
other documents as such Letter of Credit Issuer customarily requires in
connection therewith.

                  (b) The making of each Letter of Credit Request shall be
deemed to be a representation and warranty by the Borrower that such Letter
of Credit may be issued in accordance with, and it will not violate the
requirements of, Section 2.01(c). Unless the respective Letter of Credit
Issuer has received notice from the Required Banks before it issues a Letter
of Credit that one or more of the applicable conditions specified in Section
5 or 6, as the case may be, are not then satisfied, or that the issuance of
such Letter of Credit would violate Section 2.01(c), then such Letter of
Credit Issuer may issue the requested Letter of Credit for the account of the
Borrower in accordance with such Letter of Credit Issuer's usual and
customary practice.

                  2.03 LETTER OF CREDIT PARTICIPATIONS. (a) Immediately upon the
issuance by

                                     -22-
<PAGE>

a Letter of Credit Issuer of any Letter of Credit, such Letter of Credit
Issuer shall be deemed to have sold and transferred to each other RL Bank,
and each such RL Bank (each, a "Participant") shall be deemed irrevocably and
unconditionally to have purchased and received from such Letter of Credit
Issuer, without recourse or warranty, an undivided interest and
participation, to the extent of such Participant's Adjusted RL Percentage, in
such Letter of Credit, each substitute Letter of Credit, each drawing made
thereunder and the obligations of the Borrower under this Agreement with
respect thereto (although Letter of Credit Fees shall be payable directly to
the Administrative Agent for the account of the RL Banks as provided in
Section 3.01(b) and the Participants shall have no right to receive any
portion of any Facing Fees with respect to such Letters of Credit) and any
security therefor or guaranty pertaining thereto. Upon any change in the
Revolving Loan Commitments or the Adjusted RL Percentages of the RL Banks
pursuant to Section 1.13 or 13.04(b) or as a result of a Bank Default, it is
hereby agreed that, with respect to all outstanding Letters of Credit and
Unpaid Drawings with respect thereto, there shall be an automatic adjustment
to the participations pursuant to this Section 2.03 to reflect the new
Adjusted RL Percentages of the assigning and assignee Bank or of all RL
Banks, as the case may be.

                  (b) In determining whether to pay under any Letter of
Credit, no Letter of Credit Issuer shall have any obligation relative to the
Participants other than to determine that any documents required to be
delivered under such Letter of Credit have been delivered and that they
appear to substantially comply on their face with the requirements of such
Letter of Credit. Any action taken or omitted to be taken by any Letter of
Credit Issuer under or in connection with any Letter of Credit issued by it
if taken or omitted in the absence of gross negligence or willful misconduct,
shall not create for such Letter of Credit Issuer any resulting liability.

                  (c) In the event that any Letter of Credit Issuer makes any
payment under any Letter of Credit issued by it and the Borrower shall not
have reimbursed such amount in full to the Letter of Credit Issuer pursuant
to Section 2.04(a), such Letter of Credit Issuer shall promptly notify the
Administrative Agent, and the Administrative Agent shall promptly notify each
Participant of such failure, and each such Participant shall promptly and
unconditionally pay to the Administrative Agent for the account of such
Letter of Credit Issuer, the amount of such Participant's Adjusted RL
Percentage of such payment in U.S. Dollars and in same day funds. If the
Administrative Agent so notifies any Participant required to fund a payment
under a Letter of Credit prior to 11:00 A.M. (New York time) on any Business
Day, such Participant shall make available to the Administrative Agent at the
Payment Office for the account of the respective Letter of Credit Issuer such
Participant's Adjusted RL Percentage of the amount of such payment on such
Business Day in same day funds (and, to the extent such notice is given after
11:00 A.M. (New York time) on any Business Day, such Participant shall make
such payment on the immediately following Business Day). If and to the extent
such Participant shall not have so made its Adjusted RL Percentage of the
amount of such payment available to the Administrative Agent for the account
of the respective Letter of Credit Issuer, such Participant agrees to pay to
the Administrative Agent for the account of such Letter of Credit Issuer,
forthwith on demand such amount, together with interest thereon, for each day
from such date until the date such amount is paid to the Administrative Agent
for the account of the Letter of Credit Issuer at the overnight Federal Funds
Rate. The failure of any Participant to make available to the Administrative


                                     -23-
<PAGE>

Agent for the account of the respective Letter of Credit Issuer its Adjusted
RL Percentage of any payment under any Letter of Credit issued by it shall
not relieve any other Participant of its obligation hereunder to make
available to the Administrative Agent for the account of such Letter of
Credit Issuer its applicable Adjusted RL Percentage of any payment under any
such Letter of Credit on the date required, as specified above, but no
Participant shall be responsible for the failure of any other Participant to
make available to the Administrative Agent for the account of such Letter of
Credit Issuer such other Participant's Adjusted RL Percentage of any such
payment.

                  (d) Whenever any Letter of Credit Issuer receives a payment
of a reimbursement obligation as to which the Administrative Agent has
received for the account of such Letter of Credit Issuer any payments from
the Participants pursuant to clause (c) above, such Letter of Credit Issuer
shall pay to the Administrative Agent and the Administrative Agent shall
promptly pay to each Participant which has paid its Adjusted RL Percentage
thereof, in U.S. Dollars and in same day funds, an amount equal to such
Participant's Adjusted RL Percentage of the principal amount thereof and
interest thereon accruing after the purchase of the respective participations.

                  (e) Each Letter of Credit Issuer shall, promptly after each
issuance of, or amendment or modification to, a Standby Letter of Credit
issued by it, give the Administrative Agent, each Participant and the
Borrower written notice of the issuance of, or amendment or modification to,
such Standby Letter of Credit, which notice shall be accompanied by a copy of
the Standby Letter of Credit or Standby Letters of Credit issued by it and
each such amendment or modification thereto.

                  (f) Each Letter of Credit Issuer (other than BTCo) shall
deliver to the Administrative Agent, promptly on the first Business Day of
each week, by facsimile transmission, the aggregate daily Stated Amount
available to be drawn under the outstanding Trade Letters of Credit issued by
such Letter of Credit Issuer for the previous week. The Administrative Agent
shall, within 10 days after the last Business Day of each calendar month,
deliver to each Participant a report setting forth for such preceding
calendar month the aggregate daily Stated Amount available to be drawn under
all outstanding Trade Letters of Credit during such calendar month.

                  (g) The obligations of the Participants to make payments to
the Administrative Agent for the account of the respective Letter of Credit
Issuer with respect to Letters of Credit issued by it shall be irrevocable
and not subject to counterclaim, set-off or other

                                     -24-
<PAGE>

defense or any other qualification or exception whatsoever and shall be made
in accordance with the terms and conditions of this Agreement under all
circumstances, including, without limitation, any of the following
circumstances:

                    (i)    any lack of validity or enforceability of this
     Agreement or any of the other Credit Documents;

                   (ii) the existence of any claim, set-off, defense or other
     right which the Borrower or any of its Subsidiaries may have at any
     time against a beneficiary named in a Letter of Credit, any
     transferee of any Letter of Credit (or any Person for whom any such
     transferee may be acting), any Agent, any Letter of Credit Issuer,
     any Bank, or other Person, whether in connection with this
     Agreement, any Letter of Credit, the transactions contemplated
     herein or any unrelated transactions (including any underlying
     transaction between the Borrower or any of its Subsidiaries and the
     beneficiary named in any such Letter of Credit);

                  (iii) any draft, certificate or other document presented
     under the Letter of Credit proving to be forged, fraudulent, invalid
     or insufficient in any respect or any statement therein being untrue
     or inaccurate in any respect;

                   (iv) the surrender or impairment of any security for the
     performance or observance of any of the terms of any of the Credit
     Documents; or

                    (v) the occurrence of any Default or Event of Default.

                  2.04 AGREEMENT TO REPAY LETTER OF CREDIT DRAWINGS. (a) The
Borrower hereby agrees to reimburse each Letter of Credit Issuer, by making
payment to the Administrative Agent in immediately available funds at the
Payment Office, for any payment or disbursement made by such Letter of Credit
Issuer under any Letter of Credit issued by it (each such amount so paid or
disbursed until reimbursed, an "Unpaid Drawing") immediately after, and in
any event on the date of such payment or disbursement, with interest on the
amount so paid or disbursed by such Letter of Credit Issuer, to the extent
not reimbursed prior to 1:00 P.M. (New York time) on the date of such payment
or disbursement, from and including the date paid or disbursed to but not
including the date such Letter of Credit Issuer is reimbursed therefor at a
rate per annum which shall be the Applicable Margin for Revolving Loans
maintained as Base Rate Loans as in effect from time to time (plus an
additional 2% per annum if not reimbursed by the third Business Day after the
date of such payment or disbursement), such interest also to be payable on
demand; PROVIDED that it is understood and agreed, however, that the notices
referred to above in this clause (a) shall not be required to be given if a
Default or an Event of Default under such Section 10.05 shall have occurred
and be continuing (in which case the Unpaid Drawings shall be due and payable
immediately without presentment, demand, protest or notice of any kind (all
of

                                     -25-
<PAGE>

which are hereby waived by each Credit Party) and shall bear interest at a
rate per annum which shall be Applicable Margin for Revolving Loans
maintained as Base Rate Loans plus 2% on and after the third Business Day
following the respective Drawing). Each Letter of Credit Issuer shall provide
the Borrower prompt notice of any payment or disbursement made by it under
any Letter of Credit issued by it, although the failure of, or delay in,
giving any such notice shall not release or diminish the obligations of the
Borrower under this Section 2.04(a) or under any other Section of this
Agreement.

                  (b) The Borrower's obligation under this Section 2.04 to
reimburse the respective Letter of Credit Issuer with respect to drawings on
Letters of Credit (including, in each case, interest thereon) shall be
absolute and unconditional under any and all circumstances and irrespective
of any setoff, counterclaim or defense to payment which the Borrower or any
of its Subsidiaries may have or have had against such Letter of Credit
Issuer, any Agent or any Bank, including, without limitation, any defense
based upon the failure of any drawing under a Letter of Credit issued by it
to conform to the terms of the Letter of Credit or any nonapplication or
misapplication by the beneficiary of the proceeds of such drawing; PROVIDED,
HOWEVER, that the Borrower shall not be obligated to reimburse such Letter of
Credit Issuer for any wrongful payment made by such Letter of Credit Issuer
under a Letter of Credit issued by it as a result of acts or omissions
constituting willful misconduct or gross negligence on the part of such
Letter of Credit Issuer as determined by a court of competent jurisdiction.

                  2.05 INCREASED COSTS. If after the Second Restatement
Effective Date, any Letter of Credit Issuer or any Participant determines
that the adoption or effectiveness of any applicable law, rule or regulation,
order, guideline or request or any change therein, or any change in the
interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Letter of Credit Issuer or any
Participant with any request or directive (whether or not having the force of
law) by any such authority, central bank or comparable agency shall either
(i) impose, modify or make applicable any reserve, deposit, capital adequacy
or similar requirement against Letters of Credit issued by such Letter of
Credit Issuer or such Participant's participation therein (except as
contemplated by Section 4.04), or (ii) impose on any Letter of Credit Issuer
or any Participant any other conditions directly or indirectly affecting this
Agreement, any Letter of Credit or such Participant's participation therein;
and the result of any of the foregoing is to increase the cost to such Letter
of Credit Issuer or such Participant of issuing, maintaining or participating
in any Letter of Credit, or to reduce the amount of any sum received or
receivable by such Letter of Credit Issuer or such Participant hereunder or
reduce the rate of return on its capital with respect to Letters of Credit,
then, upon written demand to the Borrower by such Letter of Credit Issuer or
such Participant (a copy of which notice shall be sent by such Letter of
Credit Issuer or such Participant to the Administrative Agent), accompanied
by the certificate described in the last sentence of this Section 2.05, the
Borrower agrees, subject to the provisions of Section

                                     -26-
<PAGE>

13.18 (to the extent applicable), to pay to such Letter of Credit Issuer or
such Participant such additional amount or amounts as will compensate such
Letter of Credit Issuer or such Participant for such increased cost or
reduction. A certificate submitted to the Borrower by such Letter of Credit
Issuer or such Participant, as the case may be (a copy of which certificate
shall be sent by such Letter of Credit Issuer or such Participant to the
Administrative Agent), setting forth in reasonable detail the basis for the
determination of such additional amount or amounts necessary to compensate
such Letter of Credit Issuer or such Participant as aforesaid shall be final
and conclusive and binding on the Borrower absent manifest error, although
the failure to deliver any such certificate shall not release or diminish the
Borrower's obligations to pay additional amounts pursuant to this Section
2.05 upon subsequent receipt of such certificate.

                  SECTION 3.  FEES; COMMITMENTS.

                  3.01 FEES. (a) The Borrower shall pay to the Administrative
Agent for distribution to each Non-Defaulting Bank with a Revolving Loan
Commitment, a commitment fee (the "RL Commitment Fee") for the period from
the Original Effective Date to but not including the Revolving Loan Maturity
Date (or such earlier date as the Total Revolving Loan Commitment shall have
been terminated), computed at a rate for each day equal to the Applicable RL
Commitment Fee Percentage on the daily average Unutilized Revolving Loan
Commitment of such Non-Defaulting Bank. Accrued RL Commitment Fees shall be
due and payable quarterly in arrears on each Quarterly Payment Date and on
the Revolving Loan Maturity Date (or such earlier date upon which the Total
Revolving Loan Commitment is terminated).

                  (b) The Borrower shall pay to the Administrative Agent for
distribution to each Non-Defaulting Bank with a Tranche C Term Loan
Commitment, a commitment fee (the "C TL Commitment Fee") for the period from
the Second Restatement Effective Date to but not including the Tranche C Term
Loan Commitment Termination Date (or such earlier date as the Total Tranche C
Term Loan Commitment shall have been terminated), computed at a rate for each
day equal to 1/2 of 1% on the daily average Tranche C Term Loan Commitment of
such Non-Defaulting Bank. Accrued C TL Commitment Fees shall be due and
payable quarterly in arrears on each Quarterly Payment Date and on the
Tranche C Term Loan Termination Date (or such earlier date upon which the
Total Tranche C Term Loan Commitment is terminated).

                  (c) The Borrower shall pay to the Administrative Agent for PRO
RATA distribution to each Non-Defaulting Bank with a Revolving Loan Commitment
(based on their respective Adjusted RL Percentages), a fee in respect of each
Letter of Credit (the "Letter of Credit Fee") computed at a rate per annum equal
to the Applicable Margin for Revolving Loans maintained as Eurodollar Loans then
in effect on the daily Stated Amount of such

                                     -27-
<PAGE>

Letter of Credit. Accrued Letter of Credit Fees shall be due and payable
quarterly in arrears on each Quarterly Payment Date and upon the first day on
or after the termination of the Total Revolving Loan Commitment upon which no
Letters of Credit remain outstanding.

                  (d) The Borrower shall pay to each Letter of Credit Issuer
a fee in respect of each Letter of Credit issued by such Letter of Credit
Issuer (the "Facing Fee") computed at the rate of 1/4 of 1% per annum on the
daily Stated Amount of such Letter of Credit; PROVIDED that in no event shall
the annual Facing Fee with respect to each Letter of Credit be less than
$500; it being agreed that (x) on the date of issuance of any Letter of
Credit and on each anniversary thereof prior to the termination of such
Letter of Credit, if $500 will exceed the amount of Facing Fees that will
accrue with respect to such Letter of Credit for the immediately succeeding
12-month period, the full $500 shall be payable on the date of issuance of
such Letter of Credit and on each such anniversary thereof prior to the
termination of such Letter of Credit and (y) if on the date of the
termination of any Letter of Credit, $500 actually exceeds the amount of
Facing Fees paid or payable with respect to such Letter of Credit for the
period beginning on the date of the issuance thereof (or if the respective
Letter of Credit has been outstanding for more than one year, the date of the
last anniversary of the issuance thereof occurring prior to the termination
of such Letter of Credit) and ending on the date of the termination thereof,
an amount equal to such excess shall be paid as additional Facing Fees with
respect to such Letter of Credit on the next date upon which Facing Fees are
payable in accordance with the immediately succeeding sentence. Except as
provided in the immediately preceding sentence, accrued Facing Fees shall be
due and payable quarterly in arrears on each Quarterly Payment Date and upon
the first day on or after the termination of the Total Revolving Loan
Commitment upon which no Letters of Credit remain outstanding.

                  (e) The Borrower shall pay directly to each Letter of
Credit Issuer upon each issuance of, payment under, and/or amendment of, a
Letter of Credit issued by such Letter of Credit Issuer such amount as shall
at the time of such issuance, payment or amendment be the administrative
charge which such Letter of Credit Issuer is customarily charging for
issuances of, payments under or amendments of, letters of credit issued by it.

                  (f) The Borrower shall pay to each Agent, for its own
account, such other fees as may be agreed to in writing from time to time
between the Borrower and such Agent, when and as due.

                  (g)  All computations of Fees shall be made in accordance
with Section 13.07(b).

<PAGE>

                  3.02 VOLUNTARY TERMINATION OR REDUCTION OF TOTAL UNUTILIZED
COMMITMENT. (a) Upon at least three Business Days' prior notice to the
Administrative Agent at its Notice Office (which notice the Administrative
Agent shall promptly transmit to each of the Banks), the Borrower shall have
the right, without premium or penalty, to terminate or partially reduce the
Total Tranche C Term Loan Commitment or the Total Unutilized Revolving Loan
Commitment, PROVIDED that (v) any such termination or partial reduction shall
apply to proportionately and permanently reduce the Total Tranche C Term Loan
Commitment or the Revolving Loan Commitment, as the case may be, of each Bank
with such a Commitment, (w) any partial reduction pursuant to this Section
3.02(a) shall be in integral multiples of $1,000,000, (x) no reduction to the
Total Unutilized Revolving Loan Commitment shall be in an amount which would
cause the Revolving Loan Commitment of any RL Bank to be reduced (as required
by the preceding clause (v)) by an amount which exceeds the remainder of (A)
the Unutilized Revolving Loan Commitment of such RL Bank as in effect

purposes of this Agreement, except with respect to indemnifications under
this Agreement (including, without limitation, Sections 1.10, 1.11, 2.05,
4.04, 13.01 and 13.06), which shall survive as to such repaid Bank. Unless

Total Revolving Loan Commitment on the other hand, pursuant to this Section
3.02(b) shall apply to reduce the remaining Tranche C Term Loan Scheduled
Repayments (in the case of preceding clause (x)) or Scheduled Commitment
Reductions (in the case of preceding clause (y)), on a PRO RATA basis (based
upon the then remaining amount of each such Tranche C Term Loan Scheduled
Repayment or Scheduled Commitment Reduction, as the case may be, after giving
effect to all prior reductions thereto).

     Loans or Swingline Loans, the amount of such prepayment, the Types
     of Loans to be repaid and (in the case of Eurodollar Loans) the

     less than the Minimum Borrowing Amount applicable thereto;

                  (iii) at the time of any prepayment of Eurodollar Loans
     pursuant to this Section 4.01 on any date other than the last day of

     consent to certain proposed changes, waivers, discharges or 
     terminations with respect to this Agreement which have been

     interest, Fees and all other amounts then owing to such Bank (or 
     owing to such Bank with respect to each Tranche which gave rise to 
     the need to obtain such Bank's individual consent) in accordance

     time Schedule I shall be deemed modified to reflect the changed
     Revolving Loan Commitments), (B) in the case of the repayment of
     Tranche C Term Loans of any Bank pursuant to this clause (b), the
     Tranche C Term Loan Commitment of such Bank (to the extent not

     consents required by Section 13.12(b) in connection with the
     repayment pursuant to this clause (b) shall have been obtained;

                   (vi) each prepayment of Term Loans pursuant to this

     Repayments of the respective Tranche after giving effect to all
     prior reductions thereto).

                       4.02  MANDATORY REPAYMENTS AND COMMITMENT REDUCTIONS.
(a) (i) If on any date the sum of (x) the aggregate outstanding principal
amount of Revolving Loans made by Non-Defaulting Banks and Swingline Loans
(after giving effect to all other repayments thereof on such date) and (y)
the Letter of Credit Outstandings on such date exceeds the Adjusted Total
Revolving Loan Commitment as then in effect, the Borrower shall repay on such
date the principal of Swingline Loans, and if no Swingline Loans are or
remain outstanding, Revolving Loans of Non-Defaulting Banks in an aggregate
amount equal to such excess. If, after giving effect to the prepayment of all
outstanding Swingline Loans and all outstanding Revolving Loans of
Non-Defaulting Banks, the aggregate amount of Letter of Credit Outstandings
exceeds the Adjusted Total Revolving Loan Commitment as then in effect, the
Borrower shall pay to the Administrative Agent at the Payment Office on such
date an amount in cash and/or Cash Equivalents equal to such excess (up to
the aggregate amount of Letter of Credit Outstandings at such time) and the
Administrative Agent shall hold such payment as security for the obligations
of the Borrower to Non-Defaulting Banks hereunder pursuant to a cash
collateral agreement to be entered into in form and substance reasonably
satisfactory to the Administrative Agent.

         (ii) On any date on which the aggregate outstanding principal amount
of the

Effective Date upon which the Borrower or any of its Subsidiaries receives
Net Sale Proceeds from any Asset Sale, an amount equal to the Applicable
Prepayment Percentage of the Net Sale Proceeds from such Asset Sale shall be
applied as a mandatory repayment and/or commitment reduction in accordance

respect to any such Net Sale Proceeds received by the Borrower or any of its
Subsidiaries in connection with a Healthcare Unit Replacement, such Net Sale
Proceeds shall not give rise to a mandatory repayment (and/or commitment
reduction, as the case may be) on such date to the extent that no Default or

remaining portion shall be applied on the last day of such period as a
mandatory repayment and/or commitment reduction as provided above and (II)
(x) with respect to no more than $2,500,000 in the aggregate of such Net Sale
Proceeds received by the Borrower or its Subsidiaries in any fiscal year of

repayment (and/or commitment reduction, as the case may be) on such date to
the extent that no Default or Event of Default then exists and the Borrower
delivers a certificate to the Administrative Agent on or prior to such date
stating that such Net Sale Proceeds shall be used or contractually committed

extent permitted by Section 9.02), the purchase of the capital stock of a
Person engaged in such businesses) within 270 days following the date of

all or any portion of such Net Sale Proceeds are not so used within such
270-day period referred to in clause (i) of this clause (II)(y) because such
amount is contractually committed to be used and subsequent to such date such
contract is terminated or expires without such portion being so used, such
remaining portion shall be applied on the date of such termination or
expiration as a mandatory repayment and/or commitment reduction as provided
above.

permitted to be incurred pursuant to Section 9.04 as in effect on the Second
Restatement Effective Date) or issuance of Preferred Stock (other than (x)
Disqualified Preferred Stock to the extent the proceeds therefrom are used to

Credit Agreement) after the Original Effective Date do not exceed 
$2,500,000), an amount equal to the Applicable Prepayment Percentage of the 
Net Cash Proceeds of the respective equity issuance or capital contribution 
shall be applied as a mandatory repayment and/or commitment reduction in 
accordance with the requirements of Sections 4.02(h) and (i); provided that 
Net Cash Proceeds received by the Borrower from additional sales or issuances 
of Borrower Common Stock or Qualified Preferred Stock shall not be required 
to be applied as a mandatory repayment (and/or commitment reduction, as the 
case may be) on the date of receipt thereof, to the extent that (x) no

portion being so used, such remaining portion shall be applied on the date of
such termination or expiration as a mandatory repayment and/or commitment
reduction as provided above.

                  (f) In addition to any other mandatory repayments or
commitment reductions pursuant to this Section 4.02, within 10 days following
each date on or after the Original Effective Date on which the Borrower or
any of its Subsidiaries receives any proceeds from any Recovery Event (other
than proceeds from Recovery Events in an amount less than $1,000,000 per
Recovery Event), an amount equal to 100% of the proceeds of such Recovery
Event (net of reasonable costs (including, without limitation, legal costs
and expenses) and taxes incurred in connection with such Recovery Event and
the amount of such proceeds required to be used to repay any Indebtedness
(other than Indebtedness of the Banks pursuant to this Agreement) which is
secured by the respective assets subject to such Recovery Event) shall be
applied as a mandatory repayment and/or commitment reduction in accordance
with the requirements of Sections 4.02(h) and (i); PROVIDED that (x) so long
as no Default or Event of Default then exists and such proceeds do not exceed
$2,500,000, such proceeds shall not be required to be so applied on such date
to the extent that an Authorized Officer of the Borrower has delivered a
certificate to the Administrative Agent on or prior to such date stating that
such proceeds shall be used or shall be committed to be used to replace or
restore any properties or assets in respect of which such proceeds were paid
within 360 days following the date of such Recovery Event (which certificate
shall set forth the estimates of the proceeds to be so expended) and (y) so
long as no Default or Event of Default then exists and to the extent that (a)
the amount of such proceeds exceeds $2,500,000, (b) the amount of such
proceeds, together with other cash available to the Borrower and its
Subsidiaries and permitted to be spent by them on Capital Expenditures during
the relevant period, equals at least 100% of the cost of replacement or
restoration of the properties or assets in respect of which such proceeds
were paid as determined by the Borrower and as supported by such estimates or
bids from contractors or subcontractors or such other supporting information
as the Administrative Agent may reasonably accept, (c) an Authorized Officer
of the Borrower has delivered to the Administrative Agent a certificate on or
prior to the date the application would otherwise be required pursuant to
this Section 4.02(f) in the form described in clause (x) above and also
certifying its determination as required by preceding clause (b) and
certifying the sufficiency of business interruption insurance as required by
succeeding clause (d), and (d) an Authorized Officer of the Borrower has
delivered to the Administrative Agent such evidence as the Administrative
Agent may reasonably request in form and substance reasonably satisfactory to
the Administrative Agent establishing that the Borrower has sufficient
business interruption insurance and that the Borrower will receive payment
thereunder in such amounts and at such times as are necessary to satisfy all
obligations and expenses of the Borrower (including, without limitation, all

                                     -39-

debt service requirements, including pursuant to this Agreement), without any
delay or extension thereof, for the period from the date of the respective
casualty, condemnation or other event giving rise to the Recovery Event and
continuing through the completion of the replacement or restoration of
respective properties or assets, then the entire amount of the proceeds of
such Recovery Event and not just the portion in excess of $2,500,000 shall be
deposited with the Administrative Agent pursuant to a cash collateral
arrangement reasonably satisfactory to the Administrative Agent whereby such
proceeds shall be disbursed to the Borrower from time to time as needed to
pay or reimburse the Borrower or such Subsidiary actual costs incurred by it
in connection with the replacement or restoration of the respective
properties or assets (pursuant to such certification requirements as may be
established by the Administrative Agent), PROVIDED FURTHER, that at any time
while an Event of Default has occurred and is continuing, the Required Banks
may direct the Administrative Agent (in which case the Administrative Agent
shall, and is hereby authorized by the Borrower to, follow said directions)
to apply any or all proceeds then on deposit in such collateral account to
the repayment of Obligations hereunder in the same manner as proceeds would
be applied pursuant to the Security Agreement, and PROVIDED FURTHER, that if
all or any portion of such proceeds not required to be applied as a mandatory
repayment and/or commitment reduction pursuant to the second preceding
proviso (whether pursuant to clause (x) or (y) thereof) are either (A) not so
used or committed to be so used within 360 days after the date of the
respective Recovery Event or (B) if committed to be used within 360 days
after the date of receipt of such net proceeds and not so used within 18
months after the date of respective Recovery Event then, in either such case,
such remaining portion not used or committed to be used in the case of
preceding clause (A) and not used in the case of preceding clause (B) shall
be applied on the date occurring 360 days after the date of the respective
Recovery Event in the case of clause (A) above or the date occurring 18
months after the date of the respective Recovery Event in the case of clause
(B) above as a mandatory repayment and/or commitment reduction in accordance
with the requirements of Sections 4.02(h) and (i).

                  (g) In addition to any other mandatory repayments or
commitment reductions pursuant to this Section 4.02, on each Excess Cash Flow
Payment Date, an amount equal to the Applicable Excess Cash Flow Percentage
of the Adjusted Excess Cash Flow for the relevant Excess Cash Flow Payment
Period shall be applied as a mandatory repayment and/or commitment reduction
in accordance with the requirements of Sections 4.02(h) and (i).

                  (h) Each amount required to be applied pursuant to Sections
4.02(c), (d), (e), (f) and (g) in accordance with this Section 4.02(h) shall
be applied (i) first, to repay the outstanding principal amount of Term
Loans, with each such amount required to be applied to repay outstanding Term
Loans to be applied PRO RATA to each Tranche of Term Loans based upon the
then remaining principal amounts of the respective Tranches (with each
Tranche of Term Loans to be allocated that percentage of the amount to be
applied as is

                                     -40-
<PAGE>

equal to a fraction (expressed as a percentage) the numerator of which is
equal to the then outstanding principal amount of such Tranche of Term Loans
and the denominator of which is equal to the then outstanding principal
amount of all Term Loans), (ii) second, to the extent in excess of the
amounts required to be applied pursuant to preceding clause (i), to reduce
the Total Tranche C Term Loan Commitment and (iii) third, to the extent in
excess of the amounts required to be applied pursuant to the preceding
clauses (i) and (ii), to reduce the Total Revolving Loan Commitment (it being
understood and agreed that (x) the amount of any reduction to the Total
Tranche C Term Loan Commitment and/or Total Revolving Loan Commitment as
provided in immediately preceding clauses (ii) and (iii) shall be deemed to
be an application of proceeds for purposes of this Section 4.02(h) even
though cash is not actually applied and (y) any cash received by the Borrower
or such Subsidiary will be retained by such Person except to the extent that
such cash is otherwise required to be applied as provided in Section 4.02(a)
as a result of any reduction to the Total Revolving Loan Commitment). All
repayments or commitment reductions, as the case may be, of (x) outstanding
Term Loans and Tranche C Term Loan Commitments, on the one hand and (y)
Revolving Loan Commitments, on the other hand, pursuant to Sections 4.02(c),
(d), (e), (f) or (g) shall be applied to reduce the then remaining Scheduled
Repayments of the respective Tranche of Term Loans (in the case of preceding
clause (x)) or Scheduled Commitment Reductions (in the case of preceding
clause (y)), on a PRO RATA basis (based upon the then remaining Scheduled
Repayments of the respective Tranche or Scheduled Commitment Reductions, as
the case may be, after giving effect to all prior reductions thereto).

                  (i) With respect to each repayment of Loans required by
this Section 4.02, the Borrower may designate the Types of Loans of the
respective Tranche which are to be repaid and, in the case of Eurodollar
Loans, the specific Borrowing or Borrowings of the respective Tranche
pursuant to which made, PROVIDED that: (i) repayments of Eurodollar Loans
pursuant to this Section 4.02 may only be made on the last day of an Interest
Period applicable thereto unless (x) all Eurodollar Loans of the respective
Tranche with Interest Periods ending on such date of required repayment and
all Base Rate Loans of the respective Tranche have been paid in full and/or
(y) concurrently with such repayment, the Borrower pays all breakage costs
and other amounts owing to each Bank pursuant to Section 1.11; (ii) if any
repayment of Eurodollar Loans made pursuant to a single Borrowing shall
reduce the outstanding Eurodollar Loans made pursuant to such Borrowing to an
amount less than the Minimum Borrowing Amount applicable thereto, such
Borrowing shall be converted at the end of the then current Interest Period
into a Borrowing of Base Rate Loans; and (iii) each repayment of any Tranche
of Loans made pursuant to a Borrowing shall be applied PRO RATA among such
Tranche of Loans. In the absence of a designation by the Borrower as
described in the preceding sentence, the Administrative Agent shall, subject
to the above, make such designation in its sole discretion with a view, but
no obligation, to minimize breakage costs owing under Section 1.11.
Notwithstanding the foregoing provisions of this Section 4.02, if at any time
the mandatory repayment of Loans pursuant to Section 4.02(c), (d), (e), (f)
or (g) would result, after giving effect to the procedures set forth in this
clause

                                     -41-
<PAGE>

(i) above, in the Borrower incurring breakage costs under Section 1.10 as a
result of Eurodollar Loans being repaid other than on the last day of an
Interest Period applicable thereto (any such Eurodollar Loans, "Affected
Loans"), the Borrower may elect, by written notice to the Administrative
Agent, to have the provisions of the following sentence be applicable. At the
time any Affected Loans are otherwise required to be prepaid the Borrower may
elect to deposit 100% (or such lesser percentage elected by the Borrower as
not being repaid) of the principal amounts that otherwise would have been
paid in respect of the Affected Loans with the Administrative Agent to be
held as security for the obligations of the Borrower hereunder pursuant to a
cash collateral agreement to be entered into in form and substance
satisfactory to the Administrative Agent, with such cash collateral to be
released from such cash collateral account (and applied to repay the
principal amount of such Eurodollar Loans) upon each occurrence thereafter of
the last day of an Interest Period applicable to Eurodollar Loans of the
respective Facility (or such earlier date or dates as shall be requested by
the Borrower), with the amount to be so released and applied on the last day
of each Interest Period to be the amount of such Eurodollar Loans to which
such Interest Period applies (or, if less, the amount remaining in such cash
collateral account).

                  (j) Notwithstanding anything to the contrary contained
elsewhere in this Agreement, (i) all then outstanding Swingline Loans shall
be repaid in full on the Swingline Expiry Date and (ii) all other then
outstanding Loans shall be repaid in full on the respective Maturity Date for
such Loans.

                  4.03 METHOD AND PLACE OF PAYMENT. Except as otherwise
specifically provided herein, all payments under this Agreement or any Note
shall be made to the Administrative Agent for the ratable account of the Bank
or Banks entitled thereto not later than 12:00 Noon (New York time) on the
date when due and shall be made in immediately available funds and in U.S.
Dollars at the Payment Office. Any payments under this Agreement or under any
Note which are made later than 12:00 Noon (New York time) shall be deemed to
have been made on the next succeeding Business Day. Whenever any payment to
be made hereunder or under any Note shall be stated to be due on a day which
is not a Business Day, the due date thereof shall be extended to the next
succeeding Business Day and, with respect to payments of principal, interest
shall be payable during such extension at the applicable rate in effect
immediately prior to such extension.

                  4.04 NET PAYMENTS. (a) All payments made by the Borrower
hereunder or under any Note will be made without setoff, counterclaim or
other defense. Except as provided in Section 4.04(b), all such payments will
be made free and clear of, and without deduction or withholding for, any
present or future taxes, levies, imposts, duties, fees, assessments or other
charges of whatever nature now or hereafter imposed by any jurisdiction or by
any political subdivision or taxing authority thereof or therein with respect
to such payments (but excluding, except as provided in the second succeeding
sentence, any tax imposed on or measured by the net income, net profits or
capital (including branch profits

                                     -42-

tax) of a Bank pursuant to the laws of the jurisdiction in which it is
organized or the jurisdiction in which the principal office or applicable
lending office of such Bank is located or any subdivision thereof or therein)
and all interest, penalties or similar liabilities with respect to such
nonexcluded taxes, levies, imposts, duties, fees, assessments or other
charges (all such nonexcluded taxes, levies, imposts, duties, fees,
assessments or other charges being referred to collectively as "Taxes"). If
any Taxes are so levied or imposed, the Borrower agrees to pay the full
amount of such Taxes, and such additional amounts as may be necessary so that
every payment of all amounts due under this Agreement or under any Note,
after withholding or deduction for or on account of any Taxes, will not be
less than the amount provided for herein or in such Note. If any amounts are
payable in respect of Taxes pursuant to the preceding sentence, the Borrower
agrees to reimburse each Bank, upon the written request of such Bank, for
taxes imposed on or measured by the net income, net profits or capital
(including branch profits tax) of such Bank pursuant to the laws of the
jurisdiction in which such Bank is organized or in which the principal office
or applicable lending office of such Bank is located or under the laws of any
political subdivision or taxing authority of any such jurisdiction in which
such Bank is organized or in which the principal office or applicable lending
office of such Bank is located and for any withholding of taxes as such Bank
shall determine are payable by, or withheld from, such Bank in respect of
such amounts so paid to or on behalf of such Bank pursuant to the preceding
sentence and in respect of any amounts paid to or on behalf of such Bank
pursuant to this sentence. The Borrower will furnish to the Administrative
Agent within 45 days after the date the payment of any Taxes is due pursuant
to applicable law certified copies of tax receipts evidencing such payment by
the Borrower. The Borrower agrees to indemnify and hold harmless each Bank,
and reimburse such Bank upon its written request, for the amount of any Taxes
so levied or imposed and paid by such Bank.

                  (b) Each Bank party to this Agreement on the Second
Restatement Effective Date hereby represents that, as of the Second
Restatement Effective Date, all payments of principal, interest, and fees to
be made to it by the Borrower pursuant to this Agreement will be totally
exempt from withholding of United States federal tax. Each Bank that is not a
United States person (as such term is defined in Section 7701(a)(30) of the
Code) for U.S. Federal income tax purposes agrees to deliver to the Borrower
and the Administrative Agent on or prior to the Original Effective Date (or
the First Restatement Effective Date or the Second Restatement Effective Date
in the case of any Bank that first becomes a party hereto on the First
Restatement Effective Date or the Second Restatement Effective Date, as the
case may be), or in the case of a Bank that is an assignee or transferee of
an interest under this Agreement pursuant to Section 1.13 or 13.04 (unless
the respective Bank was already a Bank hereunder immediately prior to such
assignment or transfer), on the date of such assignment or transfer to such
Bank, (i) two accurate and complete original signed copies of Internal
Revenue Service Form 4224 or 1001 (or successor forms) certifying to such
Bank's entitlement to a complete exemption from United States withholding tax
with respect to payments to be made under this Agreement and under any Note,
or (ii) if the Bank is not a

                                     -43-
<PAGE>

"bank" within the meaning of Section 881(c)(3)(A) of the Code and cannot
deliver either Internal Revenue Service Form 1001 or 4224 pursuant to clause
(i) above, (x) a certificate substantially in the form of Exhibit D (any such
certificate, a "Section 4.04(b)(ii) Certificate") and (y) two accurate and
complete original signed copies of Internal Revenue Service Form W-8 (or
successor form) certifying to such Bank's entitlement to a complete exemption
from United States withholding tax with respect to payments of interest to be
made under this Agreement and under any Note. In addition, each Bank agrees
that from time to time after the Second Restatement Effective Date, when a
lapse in time or change in circumstances renders the previous certification
obsolete or inaccurate in any material respect, and that upon the Borrower's
reasonable request after the occurrence of any other event requiring the
delivery of a Form 1001 and Form 4224 in addition to or in replacement of the
forms previously delivered, it will deliver to the Borrower and the
Administrative Agent two new accurate and complete original signed copies of
Internal Revenue Service Form 4224 or 1001, or Form W-8 and a Section
4.04(b)(ii) Certificate, as the case may be, and such other forms as may be
required in order to confirm or establish the entitlement of such Bank to a
continued exemption from or reduction in United States withholding tax with
respect to payments under this Agreement and any Note, or it shall
immediately notify the Borrower and the Administrative Agent of its inability
to deliver any such Form or Certificate in which case such Bank shall not be
required to deliver any such Form or Certificate pursuant to this Section
4.04(b). Notwithstanding anything to the contrary contained in Section
4.04(a), but subject to Section 13.04(b) and the immediately succeeding
sentence, (x) the Borrower shall be entitled, to the extent it is required to
do so by law, to deduct or withhold income or similar taxes imposed by the
United States (or any political subdivision or taxing authority thereof or
therein) from interest, fees or other amounts payable hereunder for the
account of any Bank which is not a United States person (as such term is
defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax
purposes to the extent that such Bank has not provided to the Borrower U.S.
Internal Revenue Service Forms that establish a complete exemption from such
deduction or withholding and (y) the Borrower shall not be obligated pursuant
to Section 4.04(a) hereof to gross-up payments to be made to a Bank in
respect of income or similar taxes imposed by the United States if (I) such
Bank has not provided to the Borrower the Internal Revenue Service Forms
required to be provided to the Borrower pursuant to this Section 4.04(b) or
(II) in the case of a payment, other than interest, to a Bank described in
clause (ii) above, to the extent that such Forms do not establish a complete
exemption from withholding of such taxes. Notwithstanding anything to the
contrary contained in the preceding sentence or elsewhere in this Section
4.04 and except as set forth in Section 13.04(b), the Borrower agrees to pay
additional amounts and to indemnify each Bank in the manner set forth in
Section 4.04(a) (without regard to the identity of the jurisdiction requiring
the deduction or withholding) in respect of any Taxes deducted or withheld by
them as described in the immediately preceding sentence as a result of any
changes after the Second Restatement Effective Date in any applicable law,
treaty, governmental rule, regulation, guideline or order, or in the
interpretation thereof, relating to the deducting or withholding of such
Taxes (or, if later, the date such Bank

                                     -44-
<PAGE>

became party to this Agreement). The Borrower shall not be required to pay
any additional amounts or indemnification under Section 4.04(a) to any Bank
to the extent that the obligation to pay such additional amounts or
indemnification would not have arisen but for the representation set forth in
the first sentence of Section 4.04(b) above made by the Bank not being true.

                  (c) If the Borrower pays any additional amount under this
Section 4.04 to a Bank and such Bank determines in its sole discretion that
it has actually received or realized in connection therewith any refund or
any reduction of, or credit against, its Tax liabilities in or with respect
to the taxable year in which the additional amount is paid, such Bank shall
pay to the Borrower an amount that the Bank shall, in its sole discretion,
determine is equal to the net benefit, after tax, which was obtained by the
Bank in such year as a consequence of such refund, reduction or credit.

                  (d) Each Bank shall use reasonable efforts (consistent with
legal and regulatory restrictions and subject to overall policy
considerations of such Bank) (i) to file any certificate or document or to
furnish any information as reasonably requested by the Borrower pursuant to
any applicable treaty, law or regulation or (ii) to designate a different
applicable lending office of such Bank, if the making of such filing or the
furnishing of such information or the designation of such other lending
office would avoid the need for or reduce the amount of any additional
amounts payable by the Borrower and would not, in the sole discretion of such
Bank, be disadvantageous to such Bank.

                  (e) The provisions of this Section 4.04 are subject to the
provisions of Section 13.18 (to the extent applicable).

the ASHS Acquisition Date, the ASHS Acquired Subsidiaries) of any nature 
whatsoever (whether absolute, accrued, contingent or otherwise and whether or 
not due) which, either individually or in the aggregate, could reasonably be 
expected to be material to the Borrower and its Subsidiaries taken as a whole 
or the Borrower (or, in the event this representation is made as of the ASHS 
Acquisition Date, the ASHS Acquired Subsidiaries) and (ii) the Borrower does 
not know of any basis for the assertion against the Borrower or any of its

Adverse Effect.

                  (e) On and as of the Second Restatement Effective Date, the

furnished to the Banks for use in connection with the transactions 
contemplated hereby.

Restatement Effective Date and after giving effect to the Original

are no pending or past or, to the best knowledge of the Borrower after due 
inquiry, threatened Environmental Claims against the Borrower or any of its 
Subsidiaries or any Real Property owned or operated by the Borrower or any of 
its Subsidiaries. There are no facts, circumstances, conditions or 
occurrences on any Real Property owned or operated by the Borrower or any of 
its Subsidiaries or on any property adjoining or in the vicinity of any such 
Real Property that would reasonably be expected (i) to form the basis of an

untrue if the aggregate effect of all conditions, failures, noncompliances, 
Environmental Claims, Releases and presence of underground storage tanks, in 
each case of the types described above, would reasonably be expected to have

course of business since the dates of the respective financial statements 
referred to therein), free and clear of all Liens, other than Permitted Liens.

of the Borrower) for the payment of, all federal, state and foreign income 
taxes applicable for all prior fiscal years and for the current fiscal year 
to date. There is no material action, suit, proceeding, investigation, audit, 
or claim now pending or, to the knowledge of the Borrower or any of its 
Subsidiaries, threatened by any authority regarding any taxes relating to the 
Borrower or any of its Subsidiaries. Neither the Borrower nor any of its 
Subsidiaries has entered into an agreement or waiver or been requested to 
enter into an agreement or waiver extending any statute of limitations 
relating to the payment or collection of taxes of the Borrower or any of its 
Subsidiaries, or is aware of any circumstances that would cause the taxable 
years or other taxable periods of the Borrower or any of its Subsidiaries not 
to be subject to the normally applicable statute of limitations.

         with reasonable promptness, such other information or documents
         (financial or otherwise) as any Agent on its own behalf or on behalf of
         the Required Banks may reasonably request from time to time.

                  8.02 BOOKS, RECORDS AND INSPECTIONS. The Borrower will, and

Subsidiaries to, permit, upon notice to the chief financial officer or other
Authorized Officer of the Borrower, officers and designated representatives of
the Agents or the Required Banks to visit and inspect any of the properties or
assets of the Borrower and any of its Subsidiaries in whomsoever's possession,

companies, insurance on all its property in at least such amounts and against at
least such risks as is consistent and in accordance with industry practice and
(ii) furnish to each Agent and each of the Banks, upon request, full information
as to the insurance carried. In addition to the requirements of the immediately
preceding sentence, the Borrower will at all times cause insurance of the types
described in Schedule VIII to be maintained (with the same scope of coverage as
that 

                                     -77-
<PAGE>

described in Schedule VIII) at levels which are consistent with its practices 
immediately before the Second Restatement Effective Date, taking into account 
the age and fair market value of equipment. Such insurance shall include 
physical damage insurance on all real and personal property (whether now 
owned or hereafter acquired) on an all risk basis and business interruption 
insurance. The provisions of this Section 8.03 shall be deemed supplemental 
to, but not duplicative of, the provisions of any Security Documents that 
require the maintenance of insurance.

                  (b) The Borrower will, and will cause each of its 
Subsidiaries to, at all times keep the respective property of the Borrower 
and its Subsidiaries (except real or personal property leased or financed 
through third parties in accordance with this Agreement) insured in favor of 
the Collateral Agent, and all policies or certificates with respect to such 
insurance (and any other insurance maintained by, or on behalf of, the 
Borrower or any Subsidiary of the Borrower) (i) shall be endorsed to the 
Collateral Agent's satisfaction for the benefit of the Collateral Agent 
(including, without limitation, by naming the Collateral Agent as certificate 
holder, mortgagee and loss payee with respect to real property, certificate 
holder and loss payee with respect to personal property, additional insured 
with respect to general liability and umbrella liability coverage and 
certificate holder with respect to workers' compensation insurance), (ii) 
shall state that such insurance policies shall not be cancelled or materially 
changed without at least 30 days' prior written notice thereof by the 
respective insurer to the Collateral Agent and (iii) shall be deposited with 
the Collateral Agent.

                  (c) If the Borrower or any of its Subsidiaries shall fail 
to maintain all insurance in accordance with this Section 8.03, or if the 
Borrower or any of its Subsidiaries shall fail to so name the Collateral 
Agent as an additional insured, mortgagee or loss payee, as the case may be, 
or so deposit all certificates with respect thereto, the Administrative Agent 
and/or the Collateral Agent shall have the right (but shall be under no 
obligation) to procure such insurance, and the Credit Parties agree to 
jointly and severally reimburse the Administrative Agent or the Collateral 
Agent, as the case may be, for all costs and expenses of procuring such 
insurance.

                  8.04 PAYMENT OF TAXES. The Borrower will pay and discharge, 
and will cause each of its Subsidiaries to pay and discharge, all taxes, 
assessments and governmental charges or levies imposed upon it or upon its 
income or profits, or upon any properties belonging to it, prior to the date 
on which penalties attach thereto, and all lawful claims for sums that have 
become due and payable which, if unpaid, might become a Lien not otherwise 
permitted under Section 9.03(a); PROVIDED that neither the Borrower nor any 
of its Subsidiaries shall be required to pay any such tax, assessment, 
charge, levy or claim which is being contested in good faith and by proper 
proceedings if it has maintained adequate reserves with respect thereto in 
accordance with GAAP.

and keep in full force and effect its existence and its material rights, 
franchises, authority to do business, licenses, certifications, 
accreditations and patents, except for rights, franchises, authority to do 
business, licenses, certifications, accreditations and patents the loss of 
which (individually and in the aggregate) could not reasonably be expected to 
have a Material Adverse Effect; provided, however, that any transaction 
permitted by Section 9.02 will not constitute a breach of this Section 8.05.

                  8.06 COMPLIANCE WITH STATUTES; ETC. The Borrower will, and
will cause each of its Subsidiaries to, comply with all applicable statutes,
regulations and orders of, and all applicable restrictions imposed by, all
governmental bodies, domestic or foreign, in respect of the conduct of its
business and the ownership of its property, except for such noncompliance as
would not have a Material Adverse Effect or a material adverse effect on the
ability of any Credit Party to perform its obligations under any Credit Document
to which it is a party.

                  8.07  COMPLIANCE WITH ENVIRONMENTAL LAWS.  (a)(i)  The

transportation of Hazardous Materials to or from any such Real Property, 
unless the failure to comply with the requirements specified in clause (i) or 
(ii) above, either individually or in the aggregate, would not reasonably be 
expected to have a Material Adverse Effect.  If the Borrower or any of its 
Subsidiaries, or any tenant or occupant of any Real Property owned or 
operated by the Borrower or any of its Subsidiaries, cause or permit any 
intentional or unintentional act or omission resulting in the presence or 
Release of any Hazardous Material (except in compliance with applicable 
Environmental Laws), the Borrower agrees to undertake, and/or to cause any of 
its Subsidiaries, tenants or occupants to undertake, at their sole expense, 
any clean up, removal, remedial or other action required pursuant to 
Environmental Laws to remove and clean up any Hazardous Materials from any 
Real Property except where the failure to do so would not reasonably be 
expected to have a Material Adverse Effect; PROVIDED that neither the 
Borrower nor any of its Subsidiaries shall be required to comply with 
any such order or directive which is being contested in good faith and by 
proper proceedings so long as it has maintained adequate reserves with 
respect to such compliance to the extent required in accordance with GAAP.

Section 8.12 is operative, each of its Foreign Subsidiaries) to, grant to the 
Collateral Agent security interests and mortgages in such assets and real 
property of the Borrower and its Wholly-Owned Subsidiaries as are not covered 
by the original Security Documents, and as may be requested from time to time 
by the Administrative Agent or the Required Banks (collectively, the 
"Additional Security Documents"). All such security interests and mortgages 
shall be granted pursuant to documentation reasonably satisfactory in form 
and substance to the Collateral Agent and shall constitute valid and 
enforceable perfected security interests and mortgages superior to and prior 
to the rights of all third Persons and subject to no other Liens except for 
Permitted Liens. The Additional Security Documents or instruments related

mobile Healthcare Unit in any state in which such Healthcare Unit primarily

discretion, that such action is required to ensure the perfection of its

to be delivered to the Collateral Agent such opinions of counsel, title 
insurance and other related documents as may be reasonably requested by the 
Collateral Agent to assure itself that this Section 8.11 has been complied 
with.

                  (c) Each of the Credit Parties agrees that each action 
required above by this Section 8.11 shall be completed as soon as possible, 
but in no event later than 90 days after such action is either requested to

Banks or required to be taken by the Borrower and its Subsidiaries pursuant 
to the terms of this Section 8.11.

evidence, in form and substance mutually satisfactory 

                                     -82-
<PAGE>

to the Administrative Agent and the Borrower, with respect to any Foreign 
Subsidiary of the Borrower which has not already had all of its stock pledged 
pursuant to the Pledge Agreement that (i) a pledge of 66-2/3% or more of the 
total combined voting power of all classes of capital stock of such Foreign 
Subsidiary entitled to vote, (ii) the entering into by such Foreign 
Subsidiary of a security agreement in substantially the form of the Security 
Agreement and (iii) the entering into by such Foreign Subsidiary of a 
guaranty in substantially the form of the Subsidiaries Guaranty, in any such 
case could reasonably be expected to cause (I) the undistributed earnings of 
such Foreign Subsidiary as determined for Federal income tax purposes to be 
treated as a deemed dividend to such Foreign Subsidiary's United States 
parent for Federal income tax purposes or (II) other material adverse Federal 
income tax consequences to the Credit Parties, then in the case of a failure 
to deliver the evidence described in clause (i) above, that portion of such 
Foreign Subsidiary's outstanding capital stock so issued by such Foreign 
Subsidiary, in each case not theretofore pledged pursuant to the Pledge 
Agreement shall be pledged to the Collateral Agent for the benefit of the 
Secured Creditors pursuant to the Pledge Agreement (or another pledge 
agreement in substantially similar form, if needed), and in the case of a 
failure to deliver the evidence described in clause (ii) above, such Foreign 
Subsidiary shall execute and deliver the Security Agreement (or another 
security agreement in substantially similar form, if needed), granting the 
Secured Creditors a security interest in all of such Foreign Subsidiary's 
assets and securing the Obligations of the Borrower under the Credit 
Documents and under any Interest Rate Protection Agreement or Other Hedging 
Agreement and, in the event the Subsidiaries Guaranty shall have been 
executed by such Foreign Subsidiary, the obligations of such Foreign 
Subsidiary thereunder, and in the case of a failure to deliver the evidence 
described in clause (iii) above, such Foreign Subsidiary shall execute and 
deliver the Subsidiaries Guaranty (or another guaranty in substantially 
similar form, if needed), guaranteeing the Obligations of the Borrower under 
the Credit Documents and under any Interest Rate Protection Agreement or 
Other Hedging Agreement, in each case to the extent that the entering into of 
such Security Agreement or Subsidiaries Guaranty is permitted by the laws of 
the respective foreign jurisdiction and with all documents delivered pursuant 
to this Section 8.12 to be in form and substance reasonably satisfactory to 
the Administrative Agent and/or the Collateral Agent.

                  8.13 USE OF PROCEEDS. All proceeds of the Loans shall be used
as provided in Section 7.05.

this Section 8.14 and the requirements contained in the definition of Permitted
Acquisition, the Borrower and any of its Wholly-Owned Domestic Subsidiaries may
from time to time effect Permitted Acquisitions, so long as (in each case except
to the extent the Required Banks otherwise specifically agree in writing in the
case of a specific Permitted Acquisition): (i) no Default or Event of Default
shall be in existence at the time of the consummation of the proposed Permitted
Acquisition or immediately after giving effect thereto; (ii) the Borrower shall
have given the Administrative Agent and the Banks at least 5 Business Days'
prior written notice 

                                     -83-


<PAGE>

of any Permitted Acquisition; (iii) calculations are made by the Borrower of 
compliance with the covenants contained in Sections 9.08, 9.09, 9.10 and 9.11 
(in the case of Section 9.11, giving effect to the last sentence appearing 
therein) for the period of four (except in the case of any determination of 
Consolidated EBITDA for purposes of such Sections, which shall be measured on 
a two-quarter annualized basis as provided in the definition thereof) 
consecutive fiscal quarters (taken as one accounting period) most recently 
ended prior to the date of such Permitted Acquisition (each, a "Calculation 
Period"), on a PRO FORMA Basis as if the respective Permitted Acquisition (as 
well as all other Permitted Acquisitions theretofore consummated after the 
first day of such Calculation Period) had occurred on the first day of such 
Calculation Period, and such recalculations shall show that such financial 
covenants would have been complied with if the Permitted Acquisition had 
occurred on the first day of such Calculation Period (for this purpose, if 
the first day of the respective Calculation Period occurs prior to the 
Original Effective Date, the First Restatement Effective Date or the Second 
Restatement Effective Date, calculated as if the covenants contained in said 
Sections 9.08, 9.09, 9.10 and 9.11 (in the case of Section 9.11, giving 
effect to the last sentence appearing therein) had been applicable from the 
first day of the Calculation Period); (iv) based on good faith projections 
prepared by the Borrower for the period from the date of the consummation of 
the Permitted Acquisition to the date which is one year thereafter, the level 
of financial performance measured by the covenants set forth in Sections 
9.08, 9.09, 9.10 and 9.11 (in the case of Section 9.11, giving effect to the 
last sentence appearing therein) shall be better than or equal to such level 
as would be required to provide that no Default or Event of Default would 
exist under the financial covenants contained in Sections 9.08, 9.09, 9.10 
and 9.11 (in the case of Section 9.11, giving effect to the last sentence 
appearing therein) of this Agreement as compliance with such covenants would 
be required through the date which is one year from the date of the 
consummation of the respective Permitted Acquisition; (v) calculations are 
made by the Borrower demonstrating compliance with an Adjusted Senior 
Leverage Ratio not to exceed 3.0:1.0 on the last day of the relevant 
Calculation Period, on a PRO FORMA Basis as if the respective Permitted 
Acquisition (as well as all other Permitted Acquisitions theretofore 
consummated after the first day of such Calculation Period) had occurred on 
the first day of such Calculation Period; (vi) all representations and 
warranties contained herein and in the other Credit Documents shall be true 
and correct in all material respects with the same effect as though such 
representations and warranties had been made on and as of the date of such 
Permitted Acquisition (both before and after giving effect thereto), unless 
stated to relate to a specific earlier date, in which case such 
representations and warranties shall be true and correct in all material 
respects as of such earlier date; (vii) the Borrower provides to the 
Administrative Agent and the Banks as soon as available but not later than 5 
Business Days after the execution thereof, a copy of any executed purchase 
agreement or similar agreement with respect to such Permitted Acquisition;

all post-closing purchase price adjustments required (in the good faith 
determination of the Borrower) in connection therewith and all capital 
expenditures (and the financing thereof) reasonably anticipated by the 
Borrower to be made in the business acquired pursuant to such 

                                     -84-
<PAGE>

Permitted Acquisition within 90 days following such Permitted Acquisition), 
the Total Unutilized Revolving Loan Commitment shall equal or exceed 
$10,000,000; and (ix) the Borrower shall have delivered to the Administrative 
Agent an officer's certificate executed by an Authorized Officer of the 
Borrower, certifying to the best of his knowledge, compliance with the 
requirements of preceding clauses (i) through (vi), inclusive, and (viii) and 
containing the calculations required by the preceding clauses (iii), (iv), 
(v) and (viii).

                  (b) At the time of each Permitted Acquisition involving the 
creation or acquisition of a Subsidiary, or the acquisition of capital stock 
or other equity interest of any Person, the capital stock or other equity 
interests thereof created or acquired in connection with such Permitted 
Acquisition shall be pledged for the benefit of the Secured Creditors 
pursuant to the Pledge Agreement in accordance with the requirements of 
Section 9.15.

                  (c) The Borrower shall cause each Subsidiary which is 
formed to effect, or is acquired pursuant to, a Permitted Acquisition to 
comply with, and to execute and deliver, all of the documentation required 
by, Sections 8.11 and 9.15, to the satisfaction of the Administrative Agent.

                  (d) The consummation of each Permitted Acquisition shall be 
deemed to be a representation and warranty by the Borrower that the 
certifications by the Borrower (or by one or more of its Authorized Officers) 
pursuant to Section 8.14(a) are true and correct and that all conditions 
thereto have been satisfied and that same is permitted in accordance with the 
terms of this Agreement, which representation and warranty shall be deemed to 
be a representation and warranty for all purposes hereunder, including, 
without limitation, Sections 6 and 10.

                  8.15  MAINTENANCE OF COMPANY SEPARATENESS.  The Borrower 
will, and will cause each of its Subsidiaries to, satisfy customary Company 
formalities, including, as applicable, the holding of regular board of 
directors' and shareholders' meetings or action by directors or shareholders 
without a meeting and the maintenance of Company offices and records.  
Neither the Borrower nor any of its Subsidiaries shall take any action, or 
conduct its affairs in a manner, which is likely to result in the Company 
existence of the Borrower or any of its Subsidiaries being ignored, or in the 
assets and liabilities of the Borrower or any of its Subsidiaries being 
substantively consolidated with those of any other such Person in a 
bankruptcy, reorganization or other insolvency proceeding.

                  8.16 PERFORMANCE OF OBLIGATIONS. The Borrower will, and will
cause each of its Subsidiaries to, perform all of its obligations under the
terms of each mortgage, deed of trust, indenture, loan agreement or credit
agreement and each other material agreement, contract or instrument by which it
is bound, except such non-performances as could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

promptly upon detecting any material failure of the Information Systems and
Equipment to be Year 2000 Compliant. In addition, the Borrower shall provide the
Administrative Agent and any Bank with such information about its year 2000

                  9.01  CHANGES IN BUSINESS.  (a)   The Borrower and its 
Subsidiaries will not engage in any business other than a Permitted Business.

         reasonable opinion of such Person, are obsolete, uneconomic or no

action, or refrain from taking such action, with respect to such Default or 
Event of Default as it shall deem advisable in the best interests of the 
Banks.

     12.06 NONRELIANCE ON AGENTS AND OTHER BANKS. Each Bank expressly 
acknowledges that none of the Administrative Agent, the Syndication Agent or 
any of their respective officers, directors, employees, agents, 
attorneys-in-fact or affiliates has made any representations or warranties to 
it and that no act by the Administrative Agent or the Syndication Agent 
hereinafter taken, including any review of the affairs of the Borrower or any 
of its Subsidiaries, shall be deemed to constitute any representation or 
warranty by the Administrative Agent or the Syndication Agent to any Bank. 
Each Bank represents to the Administrative Agent and the Syndication Agent 
that it has, independently and without reliance upon the Administrative 
Agent, the Syndication Agent or any other Bank, and based on such documents 
and information as it has deemed appropriate, made its own appraisal of and 
investigation into the business, assets, operations, property, financial and 
other condition, prospects and creditworthiness of the Borrower or its 
Subsidiaries and made its own decision to make its Loans hereunder and enter 
into this Agreement. Each Bank also represents that it will, independently 
and without reliance upon the Administrative Agent, the Syndication 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 analysis, appraisals 
and decisions in taking or not taking action under this Agreement, and to 
make such investigation as it deems necessary to inform itself as to the 
business, assets, operations, property, financial and other condition, 
prospects and creditworthiness of the Borrower or its Subsidiaries. Neither 
the Administrative Agent nor the Syndication Agent shall have any duty or 
responsibility to provide any Bank with any credit or other information 
concerning the business, operations, assets, property, financial and other 
condition, prospects or creditworthiness of the Borrower or its Subsidiaries 
which may come into the possession of the Administrative Agent, the 
Syndication Agent or any of their respective officers, directors, employees, 
agents, attorneys-in-fact or affiliates.

     12.07 INDEMNIFICATION. The Banks agree to indemnify each of the 

                                     -158-


<PAGE>

Administrative Agent and the Syndication Agent in their respective capacities
as such ratably according to their respective "percentages" as used in
determining the Required Banks at such time or, if the Commitments have
terminated and all Loans have been repaid in full, as determined immediately
prior to such termination and repayment (with such "percentages" to be
determined as if there are no Defaulting Banks), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, reasonable expenses or disbursements of any kind whatsoever
which may at any time (including, without limitation, at any time following
the payment of the Obligations) be imposed on, incurred by or asserted
against the Administrative Agent or the Syndication Agent in their respective
capacities as such in any way relating to or arising out of this Agreement or
any other Credit Document, or any documents contemplated by or referred to
herein or the transactions contemplated hereby or any action taken or omitted
to be taken by the Administrative Agent or the Syndication Agent under or in
connection with any of the foregoing, but only to the extent that any of the
foregoing is not paid by the Borrower or any of its Subsidiaries; PROVIDED
that no Bank shall be liable to the Administrative Agent or the Syndication
Agent for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting primarily from the gross negligence or willful
misconduct of the Administrative Agent or the Syndication Agent. If any
indemnity furnished to the Administrative Agent or the Syndication Agent for
any purpose shall, in the opinion of the Administrative Agent or the
Syndication Agent, be insufficient or become impaired, the Administrative
Agent or the Syndication Agent, as the case may be, may call for additional
indemnity and cease, or not commence, to do the acts indemnified against
until such additional indemnity is furnished. The agreements in this Section
12.07 shall survive the payment of all Obligations.

                  12.08 AGENTS IN THEIR INDIVIDUAL CAPACITIES. Each of the
Administrative Agent and the Syndication Agent and their respective
affiliates may make loans to, accept deposits from and generally engage in
any kind of business with the Borrower and its Subsidiaries as though the
Administrative Agent or the Syndication Agent, as the case may be, were not
the Administrative Agent or the Syndication Agent, as the case may be,
hereunder. With respect to the Loans made by it and all Obligations owing to
it, each of the Administrative Agent and the Syndication Agent shall have the
same rights and powers under this Agreement as any Bank and may exercise the
same as though it were not the Administrative Agent or the Syndication Agent,
as the case may be, and the terms "Bank" and "Banks" shall include the
Administrative Agent and the Syndication Agent in their individual capacities.

                  12.09 HOLDERS. The Administrative Agent may deem and treat
the payee of any Note as the owner thereof for all purposes hereof unless and
until a written notice of the assignment, transfer or endorsement thereof, as
the case may be, shall have been filed with the Administrative Agent. Any
request, authority or consent of any Person or entity who, at the time of
making such request or giving such authority or consent, is the holder of any

                                    -159-
<PAGE>

Note shall be conclusive and binding on any subsequent holder, transferee,
assignee or indorsee, as the case may be, of such Note or of any Note or
Notes issued in exchange therefor.

                  12.10  RESIGNATION OF THE AGENTS.  (a)  The Administrative
Agent may resign from the performance of all its functions and duties
hereunder and/or under the other Credit Documents at any time by giving 30
Business Days' prior written notice to the Borrower and the Banks.  Such
resignation shall take effect upon the appointment of a successor
Administrative Agent pursuant to clauses (b) and (c) below or as otherwise
provided below.

                  (b) Upon any such notice of resignation, the Required Banks
shall appoint a successor Administrative Agent hereunder or thereunder who
shall be a commercial bank or trust company reasonably acceptable to the
Borrower.

                  (c) If a successor Administrative Agent shall not have been
so appointed within such 30 Business Day period, the Administrative Agent,
with the consent of the Borrower (which consent shall not be unreasonably
withheld or delayed), shall then appoint a successor Administrative Agent who
shall serve as Administrative Agent hereunder or thereunder until such time,
if any, as the Required Banks appoint a successor Administrative Agent as
provided above.

                  (d) If no successor Administrative Agent has been appointed
pursuant to clause (b) or (c) above by the 30th Business Day after the date
such notice of resignation was given by the Administrative Agent, the
Administrative Agent's resignation shall become effective and the Required
Banks shall thereafter perform all the duties of the Administrative Agent
hereunder and/or under any other Credit Document until such time, if any, as
the Banks appoint a successor Administrative Agent as provided above.

                  (e) The Syndication Agent may resign from the performance
of all its functions and duties hereunder and/or under the other Credit
Documents at any time by giving five Business Days' prior written notice to
the Banks. Such resignation shall take effect at the end of such five
Business Day period. Upon the effectiveness of the resignation of the
Syndication Agent, the Administrative Agent shall assume all of the functions
and duties of the Syndication Agent hereunder and/or under the other Credit
Documents.

                  SECTION 13.  MISCELLANEOUS.

                                    -160-
<PAGE>

                  13.01 PAYMENT OF EXPENSES, ETC. The Borrower agrees to: (i)
whether or not the transactions herein contemplated are consummated, pay all
reasonable out-of-pocket costs and expenses of the Agents (including, without
limitation, the reasonable fees and disbursements of White & Case and local
counsel) in connection with the negotiation, preparation, execution and
delivery of the Credit Documents and the documents and instruments referred
to therein and any amendment, waiver or consent relating thereto and in
connection with the Agents' syndication efforts with respect to this
Agreement; (ii) pay all reasonable out-of-pocket costs and expenses of each
Agent, each Letter of Credit Issuer and each of the Banks in connection with
the enforcement of the Credit Documents and the documents and instruments
referred to therein and, after an Event of Default shall have occurred and be
continuing, the protection of the rights of each Agent, each Letter of Credit
Issuer and each of the Banks thereunder (including, without limitation, the
reasonable fees and disbursements of counsel (including in-house counsel) for
each Agent, for each Letter of Credit Issuer and for each of the Banks);
(iii) pay and hold each of the Banks harmless from and against any and all
present and future stamp and other similar taxes with respect to the
foregoing matters and save each of the Banks harmless from and against any
and all liabilities with respect to or resulting from any delay or omission
(other than to the extent attributable to such Bank) to pay such taxes; and
(iv) indemnify each Agent, the Collateral Agent, each Letter of Credit Issuer
and each Bank, their respective officers, directors, employees,
representatives, trustees and agents from and hold each of them harmless
against any and all losses, liabilities, claims, damages or expenses incurred
by any of them as a result of, or arising out of, or in any way related to,
or by reason of, (a) any investigation, litigation or other proceeding
(whether or not any Agent, the Collateral Agent, any Letter of Credit Issuer
or any Bank is a party thereto and whether or not any such investigation,
litigation or other proceeding is between or among any Agent, the Collateral
Agent, any Letter of Credit Issuer, any Bank, any Credit Party or any third
Person or otherwise) related to the entering into and/or performance of this
Agreement or any other Document or the use of the proceeds of any Loans
hereunder or the Original Transaction, the MTI Transaction or the Transaction
or the consummation of any other transactions contemplated in any Document
(but excluding any such losses, liabilities, claims, damages or expenses to
the extent incurred by reason of the gross negligence or willful misconduct
of the Person to be indemnified), or (b) the actual or alleged presence of
Hazardous Materials in the air, surface water or groundwater or on the
surface or subsurface of any Real Property or any Environmental Claim, in
each case, including, without limitation, the reasonable fees and
disbursements of counsel and independent consultants incurred in connection
with any such investigation, litigation or other proceeding.

                  13.02 RIGHT OF SETOFF. In addition to any rights now or
hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence of an Event of Default, each
Agent, each Letter of Credit Issuer and each Bank is hereby authorized at any
time or from time to time, without presentment, demand, protest

                                    -161-
<PAGE>

or other notice of any kind to the Borrower or any of its Subsidiaries or to
any other Person, any such notice being hereby expressly waived, to set off
and to appropriate and apply any and all deposits (general or special) and
any other Indebtedness at any time held or owing by such Agent, such Letter
of Credit Issuer or such Bank (including, without limitation, by branches and
agencies of such Agent, such Letter of Credit Issuer and such Bank wherever
located) to or for the credit or the account of the Borrower or any of its
Subsidiaries against and on account of the Obligations of the Borrower or any
of its Subsidiaries to such Agent, such Letter of Credit Issuer or such Bank
under this Agreement or under any of the other Credit Documents, including,
without limitation, all interests in Obligations of the Borrower or any of
its Subsidiaries purchased by such Bank pursuant to Section 13.06(b), and all
other claims of any nature or description arising out of or connected with
this Agreement or any other Credit Document, irrespective of whether or not
such Agent, such Letter of Credit Issuer or such Bank shall have made any
demand hereunder and although said Obligations shall be contingent or
unmatured.

                  13.03 NOTICES. Except as otherwise expressly provided
herein, all notices and other communications provided for hereunder shall be
in writing (including telegraphic, telex, facsimile or cable communication)
and mailed, telegraphed, telexed, telecopied, cabled or delivered, if to any
Credit Party, at the address specified opposite its signature below or in the
other relevant Credit Documents, as the case may be; if to any Bank, at its
address specified for such Bank on Schedule II; or, at such other address as
shall be designated by any party in a written notice to the other parties
hereto. All such notices and communications shall be mailed, telegraphed,
telexed, telecopied or cabled or sent by overnight courier, and shall be
effective when received.

                  13.04 BENEFIT OF AGREEMENT. (a) This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the respective
successors and assigns of the parties hereto; PROVIDED, HOWEVER, the Borrower
may not assign or transfer any of its rights, obligations or interest
hereunder or under any other Credit Document without the prior written
consent of the Banks and, PROVIDED FURTHER, that, although any Bank may grant
participations in its rights hereunder, such Bank shall remain a "Bank" for
all purposes hereunder (and may not transfer or assign all or any portion of
its Commitments or Loans hereunder except as provided in Section 13.04(b))
and the participant shall not constitute a "Bank" hereunder and, PROVIDED
FURTHER, that no Bank shall transfer or grant any participation under which
the participant shall have rights to approve any amendment to or waiver of
this Agreement or any other Credit Document except to the extent such
amendment or waiver would (i) extend the final scheduled maturity of any
Loan, Note or Letter of Credit (unless such Letter of Credit is not extended
beyond the Revolving Loan Maturity Date) in which such participant is
participating, or reduce the rate or extend the time of payment of interest
or Fees thereon (except in connection with a waiver of applicability of any
post-default increase in interest rates) or reduce the principal amount
thereof, or increase the amount of the participant's participation over the
amount thereof then in effect (it being

                                    -162-
<PAGE>

understood that a waiver of any Default or Event of Default or of a mandatory
reduction in the Total Commitment or of a mandatory repayment of Loans shall
not constitute a change in the terms of such participation, that an increase
in any Commitment or Loan shall be permitted without the consent of any
participant if the participant's participation is not increased as a result
thereof and that any amendment or modification to the financial definitions
in this Agreement shall not constitute a reduction in any rate of interest or
fees for purposes of this clause (i)), (ii) consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement or (iii) release all or substantially all of the Collateral under
all of the Security Documents (except as expressly provided in the Security
Documents) supporting the Loans hereunder in which such participant is
participating. In the case of any such participation, the participant shall
not have any rights under this Agreement or any of the other Credit Documents
(the participant's rights against such Bank in respect of such participation
to be those set forth in the agreement executed by such Bank in favor of the
participant relating thereto) and all amounts payable by the Borrower
hereunder shall be determined as if such Bank had not sold such participation.

                  (b) Notwithstanding the foregoing, any Bank (or any Bank
together with one or more other Banks) may (x) assign all or a portion of its
Revolving Loan Commitment (and related outstanding Obligations hereunder)
and/or its outstanding Term Loans (or, if prior to the termination of the
Total Tranche C Term Loan Commitment, Tranche C Term Loan Commitments) to (i)
its parent company and/or any affiliate of such Bank which is at least 50%
owned by such Bank or its parent company or to one or more Banks or (ii) in
the case of any Bank that is a fund that invests in bank loans, any other
fund that invests in bank loans and is managed by the same investment advisor
of such Bank or by an Affiliate of such investment advisor or (y) assign all,
or if less than all, a portion equal to at least $5,000,000 in the aggregate
for the assigning Bank or assigning Banks, of such Revolving Loan Commitments
(and related outstanding Obligations hereunder) and outstanding principal
amount of Term Loans (or, if prior to the termination of the Total Tranche C
Term Loan Commitment, Tranche C Term Loan Commitments) to one or more
Eligible Transferees (treating (x) any fund that invests in bank loans and
(y) any other fund that invests in bank loans and is managed by the same
investment advisor as such fund or by an Affiliate of such investment
advisor, as a single Eligible Transferee), each of which assignees shall
become a party to this Agreement as a Bank by execution of an Assignment and
Assumption Agreement, PROVIDED that (i) at such time Schedule I shall be
deemed modified to reflect the Commitments and/or outstanding Term Loans, as
the case may be, of such new Bank and of the existing Banks, (ii) upon
surrender of the old Notes (or the furnishing of a standard indemnity letter
from the respective assigning Bank in respect of any lost Notes), new Notes
will be issued, at the Borrower's expense, to such new Bank and to the
assigning Bank, such new Notes to be in conformity with the requirements of
Section 1.05 (with appropriate modifications) to the extent needed to reflect
the revised Commitments and/or outstanding Term Loans, as the case may be,
(iii) the consent of the Administrative Agent and, so long as no Default or
Event of Default is then in existence, the Borrower shall be required in

                                    -163-
<PAGE>

connection with any assignment to an Eligible Transferee pursuant to clause
(y) of this Section 13.04(b) (which consent, in each case, shall not be
unreasonably withheld or delayed), (iv) the consent of each Letter of Credit
Issuer shall be required in connection with any assignment of Revolving Loan
Commitments pursuant to clause (y) of this Section 13.04(b) (which consent
shall not be unreasonably withheld or delayed) and (v) the Administrative
Agent shall receive at the time of each assignment, from the assigning or
assignee Bank, the payment of a non-refundable assignment fee of $3,500 and,
provided further, that such transfer or assignment will not be effective
until recorded by the Administrative Agent on the Register pursuant to
Section 13.17. To the extent of any assignment pursuant to this Section
13.04(b), the assigning Bank shall be relieved of its obligations hereunder
with respect to its assigned Commitments and/or outstanding Term Loans. At
the time of each assignment pursuant to this Section 13.04(b) to a Person
which is not already a Bank hereunder and which is not a United States person
(as such term is defined in Section 7701(a)(30) of the Code) for Federal
income tax purposes, the respective assignee Bank shall provide to the
Borrower and the Administrative Agent the appropriate Internal Revenue
Service Forms (and, if applicable a Section 4.04(b)(ii) Certificate)
described in Section 4.04(b). To the extent that an assignment of all or any
portion of a Bank's Commitment and outstanding Obligations pursuant to
Section 1.13 or this Section 13.04(b) would, due to circumstances existing at
the time of such assignment, result in increased costs under Section 1.10,
1.11, 2.05 or 4.04 from those being charged by the respective assigning Bank
prior to such assignment, then the Borrower shall not be obligated to pay
such increased costs (although the Borrower shall be obligated to pay any
other increased costs of the type described above resulting from changes
after the date of the respective assignment). Notwithstanding anything to the
contrary contained above, at any time after the termination of the Total
Revolving Loan Commitment, if any Revolving Loans or Letters of Credit remain
outstanding, assignments may be made as provided above, except that the
respective assignment shall be of a portion of the outstanding Revolving
Loans of the respective RL Bank and its participation in Letters of Credit
and its obligation to make Mandatory Borrowings, although any such assignment
effected after the termination of the Total Revolving Loan Commitment shall
not release the assigning RL Bank from its obligations as a Participant with
respect to outstanding Letters of Credit or to fund its share of any
Mandatory Borrowing (although the respective assignee may agree, as between
itself and the respective assigning RL Bank, that it shall be responsible for
such amounts).

                  (c) Nothing in this Agreement shall prevent or prohibit any
Bank or BTCo from pledging its Loans and Notes hereunder to a Federal Reserve
Bank in support of borrowings made by such Bank from such Federal Reserve
Bank and, with the consent of the Administrative Agent, any Bank which is a
fund may pledge all or any portion of its Notes or Loans to its trustee in
support of its obligations to its trustee. No pledge pursuant to this clause
(c) shall release the transferor Bank from any of its obligations hereunder.

                  13.05 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay
on the part of

                                    -164-
<PAGE>

any Agent or any Bank in exercising any right, power or privilege hereunder
or under any other Credit Document and no course of dealing between any
Credit Party and any Agent or any Bank shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege
hereunder or under any other Credit Document preclude any other or further
exercise thereof or the exercise of any other right, power or privilege
hereunder or thereunder. The rights and remedies herein expressly provided
are cumulative and not exclusive of any rights or remedies which any Agent or
any Bank would otherwise have. No notice to or demand on any Credit Party in
any case shall entitle any Credit Party to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the rights
of the Agents or the Banks to any other or further action in any
circumstances without notice or demand.

                  13.06 PAYMENTS PRO RATA. (a) The Administrative Agent
agrees that promptly after its receipt of each payment from or on behalf of
any Credit Party in respect of any Obligations of such Credit Party, it
shall, except as otherwise provided in this Agreement, distribute such
payment to the Banks (other than any Bank that has consented in writing to
waive its PRO RATA share of such payment) PRO RATA based upon their
respective shares, if any, of the Obligations with respect to which such
payment was received.

                  (b) Each of the Banks agrees that, if it should receive any
amount hereunder (whether by voluntary payment, by realization upon security,
by the exercise of the right of setoff or banker's lien, by counterclaim or
cross action, by the enforcement of any right under the Credit Documents, or
otherwise) which is applicable to the payment of the principal of, or
interest on, the Loans, Unpaid Drawings or Fees, of a sum which with respect
to the related sum or sums received by other Banks is in a greater proportion
than the total of such Obligation then owed and due to such Bank bears to the
total of such Obligation then owed and due to all of the Banks immediately
prior to such receipt, then such Bank receiving such excess payment shall
purchase for cash without recourse or warranty from the other Banks an
interest in the Obligations of the respective Credit Party to such Banks in
such amount as shall result in a proportional participation by all of the
Banks in such amount; PROVIDED, that if all or any portion of such excess
amount is thereafter recovered from such Bank, such purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest.

                  13.07 CALCULATIONS; COMPUTATIONS. (a) The financial
statements to be furnished to the Banks pursuant hereto shall be made and
prepared in accordance with GAAP consistently applied throughout the periods
involved (except as set forth in the notes thereto or as otherwise disclosed
in writing by the Borrower to the Banks); PROVIDED that except as otherwise
specifically provided herein, all computations determining compliance with
Sections 4.02, 8.14 and 9, including definitions used therein shall, in each
case, utilize accounting principles and policies in effect at the time of the
preparation of, and in conformity with those used to prepare, the December
31, 1997 financial statements of the Borrower delivered

                                    -165-
<PAGE>

to the Banks pursuant to Section 7.10(b); PROVIDED FURTHER, that (i) to the
extent expressly required pursuant to the provisions of this Agreement,
certain calculations shall be made on a PRO FORMA Basis, (ii) to the extent
compliance with any of Sections 9.08, 9.09, 9.10 or 9.11 would include
periods occurring prior to the Original Effective Date, the First Restatement
Effective Date or the Second Restatement Effective Date, such calculation
shall be adjusted on a PRO FORMA Basis to give effect to the Original
Transaction, the MTI Transaction or the Transaction (other than the ASHS
Acquisition and the ASHS Acquired Subsidiaries Refinancing), as the case may
be, as if same had occurred on the first day of the respective period and
(iii) in the case of any determinations of Consolidated Interest Expense and
Consolidated Fixed Charges for any portion of any Test Period which ends
prior to the Second Restatement Effective Date or the ASHS Acquisition Date,
all computations determining compliance with Sections 9.08 and 9.10 shall be
calculated in accordance with the definition of Test Period contained herein.

                  (b) All computations of interest and Fees hereunder shall
be made on the actual number of days elapsed over a year of 360 days.

                  13.08 GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE. (a)
THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH
AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. Any legal action or
proceeding with respect to this Agreement or any other Credit Document may be
brought in the courts of the State of New York or of the United States for
the Southern District of New York, and, by execution and delivery of this
Agreement, the Borrower hereby irrevocably accepts for itself and in respect
of its property, generally and unconditionally, the jurisdiction of the
aforesaid courts. The Borrower hereby irrevocably designates, appoints and
empowers CT Corporation System, with offices on the date hereof at 1633
Broadway, New York, New York 10019 as its designee, appointee and agent to
receive, accept and acknowledge for and on its behalf, and in respect of its
property, service of any and all legal process, summons, notices and
documents which may be served in any such action or proceeding. If for any
reason such designee, appointee and agent shall cease to be available to act
as such, the Borrower agrees to designate a new designee, appointee and agent
in New York City on the terms and for the purposes of this provision
satisfactory to the Administrative Agent under this Agreement. The Borrower
hereby further irrevocably waives any claim that any such courts lack
jurisdiction over the Borrower, and agrees not to plead or claim, in any
legal action or proceeding with respect to this Agreement or any other Credit
Document brought in any of the aforesaid courts, that any such court lacks
jurisdiction over the Borrower. The Borrower further irrevocably consents to
the service of process in any such action or proceeding by the mailing of
copies thereof by registered or certified mail, postage prepaid, to the
Borrower, at its address for notices pursuant to Section 13.03, such service

                                    -166-
<PAGE>

to become effective 30 days after such mailing. The Borrower hereby
irrevocably waives any objection to such service of process and further
irrevocably waives and agrees not to plead or claim in any action or
proceeding commenced hereunder or under any other Credit Document that
service of process was in any way invalid or ineffective. Nothing herein
shall affect the right of any Agent, any Bank or the holder of any Note to
serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against any Credit Party in any other
jurisdiction.

                  (b) The Borrower hereby irrevocably waives any objection
which it may now or hereafter have to the laying of venue of any of the
aforesaid actions or proceedings arising out of or in connection with this
Agreement or any other Credit Document brought in the courts referred to in
clause (a) above and hereby further irrevocably waives and agrees not to
plead or claim in any such court that any such action or proceeding brought
in any such court has been brought in an inconvenient forum.

                  13.09 COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an
original, but all of which shall together constitute one and the same
instrument. A complete set of counterparts executed by all the parties hereto
shall be lodged with the Borrower and the Administrative Agent.

                  13.10 EFFECTIVENESS. This Agreement shall become effective
on the date (the "Second Restatement Effective Date") on which (i) each of
the Borrower, each New Bank, each Bank with a Tranche C Term Loan Commitment,
each Existing Tranche B Term Loan Bank, the Required Banks (determined
immediately before the occurrence of the Second Restatement Effective Date
and without giving effect thereto), the Administrative Agent and the
Syndication Agent shall have signed a counterpart hereof (whether the same or
different counterparts) and shall have delivered the same (including by way
of facsimile transmission) to the Administrative Agent and (ii) the
conditions contained in Sections 5 and 6 are met to the satisfaction of the
Agents and the Required Banks (determined immediately after the occurrence of
the Second Restatement Effective Date). Unless the Administrative Agent has
received actual notice from any Bank that the conditions contained in
Sections 5 and 6 have not been met to its satisfaction, upon the satisfaction
of the condition described in clause (i) of the immediately preceding
sentence and upon the Administrative Agent's good faith determination that
the conditions described in clause (ii) of the immediately preceding sentence
have been met, then the Second Restatement Effective Date shall have been
deemed to have occurred, regardless of any subsequent determination that one
or more of the conditions thereto had not been met (although the occurrence
of the Second Restatement Effective Date shall not release the Borrower from
any liability for failure to satisfy one or more of the applicable conditions
contained in Section 5 or 6). The Administrative Agent will give the Borrower
and each Bank prompt written notice of the occurrence of the Second
Restatement Effective Date.

                  13.11 HEADINGS DESCRIPTIVE. The headings of the several
sections and subsections of this Agreement are inserted for convenience only
and shall not in any way affect the meaning or construction of any provision
of this Agreement.

                  13.12 AMENDMENT OR WAIVER; ETC. (a) Neither this Agreement
nor any other Credit Document nor any terms hereof or thereof may be changed,
waived, discharged or terminated unless such change, waiver, discharge or
termination is in writing signed by the respective Credit Parties party
thereto and the Required Banks, PROVIDED that no such change, waiver,
discharge or termination shall, without the consent of each Bank (other than
a Defaulting Bank) (with Obligations being directly affected thereby in the
case of the following clause (i)), (i) extend the final scheduled maturity of
any Loan or Note or extend the stated maturity of any Letter of Credit beyond
the Revolving Loan Maturity Date, or reduce the rate or extend the time of
payment of interest or Fees thereon, or reduce the principal amount thereof
(it being understood that any amendment or modification to the financial
definitions in this Agreement shall not constitute a reduction in any rate of
interest or fees for purposes of this clause (i)), (ii) release all or
substantially all of the Collateral (except as expressly provided in the
Security Documents) under all the Security Documents, (iii) amend, modify or
waive any provision of this Section 13.12, (iv) reduce the percentage

on substantially the same basis as the extensions of Term Loans and Revolving
Loan Commitments are included on the Effective Date) or (v) consent to the
assignment or transfer by the Borrower of any of its rights and obligations
under this Agreement; PROVIDED FURTHER, that no such change, waiver,
discharge or termination shall (v) increase the Commitments of any Bank over
the amount thereof then in effect without the consent of such Bank (it being
understood that waivers or modifications of conditions precedent, covenants,
Defaults or Events of Default or of a mandatory reduction in the Total
Commitment shall not constitute an increase of the Commitment of any Bank,
and that an increase in the available portion of any Commitment of any Bank
shall not constitute an increase in the Commitment of such Bank), (w) without
the consent of each Letter of Issuer, amend, modify or waive any provision of
Section 2 or alter its rights or obligations with respect to Letters of
Credit, (x) without the consent of BTCo, alter its rights or obligations with
respect to Swingline Loans, (y) without the consent of the Agent, amend,
modify or waive any provision of Section 12 as same applies to the Agent or
any other provision as same relates to the rights or obligations of the Agent
and (z) without the consent of the Collateral Agent, amend, modify or waive
any provision relating to the rights or obligations of the Collateral Agent.

                  (b) If, in connection with any proposed change, waiver,
discharge or termination of or to any of the provisions of this Agreement as
contemplated by clauses (i) through (v), inclusive, of the first proviso to
Section 13.12(a), the consent of the Required Banks is obtained but the
consent of one or more of such other Banks whose consent is

                                    -168-
<PAGE>

required is not obtained, then the Borrower shall have the right, so long as
all non-consenting Banks whose individual consent is required are treated as
described in either clause (A) or (B) below, to either (A) replace each such
non-consenting Bank or Banks (or, at the option of the Borrower if the
respective Bank's consent is required with respect to less than all Tranches
of Loans (or related Commitments), to replace only the Revolving Loan
Commitments and/or Loans of the respective non-consenting Bank which gave
rise to the need to obtain such Bank's individual consent) with one or more
Replacement Banks pursuant to Section 1.13 so long as at the time of such
replacement, each such Replacement Bank consents to the proposed change,
waiver, discharge or termination or (B) terminate such non-consenting Bank's
Revolving Loan Commitment (if such Bank's consent is required as a result of
its Revolving Loan Commitment), Term Loan Commitment (if prior to the Term
Loan Commitment Termination Date and if such Bank's consent is required as a
result of its Term Loan Commitment) and/or repay each Tranche of outstanding
Loans of such Bank which gave rise to the need to obtain such Bank's consent
and/or cash collateralize its applicable Adjusted RL Percentage of the Letter
of Credit of Outstandings, in accordance with Sections 3.02(b) and/or
4.01(b), PROVIDED that, unless the Commitments which are terminated and Loans
which are repaid pursuant to preceding clause (B) are immediately replaced in
full at such time through the addition of new Banks or the increase of the
Commitments and/or outstanding Loans of existing Banks (who in each case must
specifically consent thereto), then in the case of any action pursuant to
preceding clause (B), the Required Banks (determined after giving effect to
the proposed action) shall specifically consent thereto, PROVIDED FURTHER,
that the Borrower shall not have the right to replace a Bank, terminate its
Revolving Loan Commitment or Term Loan Commitment or repay its Loans solely
as a result of the exercise of such Bank's rights (and the withholding of any
required consent by such Bank) pursuant to the second proviso to Section
13.12(a).

                  13.13 SURVIVAL. All indemnities set forth herein including,
without limitation, in Sections 1.10, 1.11, 2.05, 4.04, 12.07 and 13.01,
shall, subject to the provisions of Section 13.18 (to the extent applicable),
survive the execution and delivery of this Agreement and the making and
repayment of the Loans.

                  13.14  DOMICILE OF LOANS AND COMMITMENTS.  Each Bank may
transfer and carry its Loans and/or Commitments at, to or for the account of
any branch office, subsidiary or affiliate of such Bank; PROVIDED, that the
Borrower shall not be responsible for costs arising under Section 1.10, 1.11,
2.05 or 4.04 resulting from any such transfer (other than a transfer pursuant
to Section 1.12) to the extent such costs would not otherwise be applicable
to such Bank in the absence of such transfer.

                  13.15 CONFIDENTIALITY. (a) Each of the Banks agrees that it
will use its reasonable efforts not to disclose without the prior consent of the
Borrower (other than to its directors, employees, auditors, counsel or other
professional advisors, to affiliates or to another Bank if the Bank or such
Bank's holding or parent company in its sole discretion

                                    -169-
<PAGE>

determines that any such party should have access to such information) any
information with respect to the Borrower or any of its Subsidiaries which is
furnished pursuant to this Agreement; PROVIDED that any Bank may disclose any
such information (a) as has become generally available to the public, (b) as
may be required or appropriate (x) in any report, statement or testimony
submitted to any municipal, state or Federal regulatory body having or
claiming to have jurisdiction over such Bank or to the Federal Reserve Board
or the Federal Deposit Insurance Corporation or similar organizations
(whether in the United States or elsewhere) or their successors or (y) in
connection with any request or requirement of any such regulatory body, (c)
as may be required or appropriate in response to any summons or subpoena or
in connection with any litigation, (d) to comply with any law, order,
regulation or ruling applicable to such Bank, and (e) to any prospective
transferee in connection with any contemplated transfer of any of the Notes
or any interest therein by such Bank; PROVIDED that such prospective
transferee agrees to be bound by this Section 13.15 to the same extent as
such Bank.

                  (b) The Borrower hereby acknowledges and agrees that each
Bank may share with any of its affiliates any information related to the
Borrower or any of its Subsidiaries (including, without limitation, any
nonpublic customer information regarding the creditworthiness of the Borrower
and its Subsidiaries), PROVIDED that such Persons shall be subject to the
provisions of this Section 13.15 to the same extent as such Bank.

                  13.16  WAIVER OF JURY TRIAL.  EACH OF THE PARTIES TO THIS
AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS
AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY
OR THEREBY.

                  13.17 REGISTER. The Borrower hereby designates the
Administrative Agent to serve as the Borrower's agent, solely for purposes of
this Section 13.17, to maintain a register (the "Register") on which it will
record the Commitments from time to time of each of the Banks, the Loans made
by each of the Banks and each repayment in respect of the principal amount of
the Loans of each Bank. Failure to make any such recordation, or any error in
such recordation shall not affect the Borrower's obligations in respect of
such Loans. With respect to any Bank, the transfer of any Commitment of such
Bank and the rights to the principal of, and interest on, any Loan shall not
be effective until such transfer is recorded on the Register maintained by
the Administrative Agent with respect to ownership of such Commitment and
Loans and prior to such recordation all amounts owing to the transferor with
respect to such Commitment and Loans shall remain owing to the transferor.
The registration of assignment or transfer of all or part of any Commitment
and Loans shall be recorded by the Administrative Agent on the Register only
upon the acceptance by the Administrative Agent of a properly executed and
delivered Assignment and Assumption Agreement pursuant to Section 13.04(b).
Coincident with the delivery of

                                    -170-
<PAGE>

such an Assignment and Assumption Agreement to the Administrative Agent for
acceptance and registration of assignment or transfer of all or part of a
Commitment and/or Loan, or as soon thereafter as practicable, the assigning
or transferor Bank shall surrender the Note evidencing such Commitment and/or
Loan, and thereupon one or more new Notes in the same aggregate principal
amount shall be issued to the assigning or transferor Bank and/or the new
Bank. The Borrower agrees to indemnify the Administrative Agent from and
against any and all losses, claims, damages and liabilities of whatsoever
nature which may be imposed on, asserted against or incurred by the
Administrative Agent in performing its duties under this Section 13.17.

                  13.18 LIMITATION ON ADDITIONAL AMOUNTS, ETC.
Notwithstanding anything to the contrary contained in Section 1.10, 1.11,
2.05 or 4.04 of this Agreement, unless a Bank gives notice to the Borrower
that it is obligated to pay an amount under such Section within six months
after the later of (x) the date the Bank incurs the respective increased
costs, Taxes, loss, expense or liability, reduction in amounts received or
receivable or reduction in return on capital or (y) the date such Bank has
actual knowledge of its incurrence of the respective increased costs, Taxes,
loss, expense or liability, reductions in amounts received or receivable or
reduction in return on capital, then such Bank shall only be entitled to be
compensated for such amount by the Borrower pursuant to said Section 1.10,
1.11, 2.05 or 4.04, as the case may be, to the extent of the costs, Taxes,
loss, expense or liability, reduction in amounts received or receivable or
reduction in return on capital that are incurred or suffered on or after the
date which occurs six months prior to such Bank giving notice to the Borrower
that it is obligated to pay the respective amounts pursuant to said Section
1.10, 1.11, 2.05 or 4.04, as the case may be. This Section 13.18 shall have
no applicability to any Section of this Agreement other than said Sections
1.10, 1.11, 2.05 and 4.04.

                  13.19 POST-CLOSING ACTIONS. Notwithstanding anything to the
contrary contained in this Agreement or the other Credit Documents, the parties
hereto acknowledge and agree that:

                  (a) SECURITY DOCUMENT FILINGS. Form UCC-1 financing statements
         delivered by the Borrower to the Collateral Agent on the ASHS
         Acquisition Date shall be filed in the appropriate governmental office
         within 10 days following the ASHS Acquisition Date.

                  (b) UCC-3 TERMINATION STATEMENTS. (i) Within 60 days
         following the Second Restatement Effective Date (or such later date
         as shall have been determined by the Administrative Agent in its
         sole discretion), the Administrative Agent shall have received Form
         UCC-3 termination statements in respect of the Liens listed on Part
         B of Schedule IX hereto and same shall be filed in the appropriate
         governmental office within 75 days following the Second Restatement
         Effective Date (or such later date 

                                    -171-
<PAGE>

         as shall have been determined by the Administrative Agent in its sole 
         discretion).

                           (ii) Within 30 days following the ASHS Acquisition
         Date (or such later date as shall have been determined by the
         Administrative Agent in its sole discretion), the Administrative
         Agent shall have received Form UCC-3 termination statements in
         respect of the Liens listed on Part C of Schedule IX (as amended on
         the ASHS Acquisition Date) and same shall be filed in the
         appropriate governmental office within 45 days following the ASHS
         Acquisition Date (or such later date as shall have been determined
         by the Administrative Agent in its sole discretion).

                  All provisions of this Credit Agreement and the other
Credit Documents (including, without limitation, all conditions precedent,
representations, warranties, covenants, events of default and other
agreements herein and therein) shall be deemed modified to the extent
necessary to effect the foregoing (and to permit the taking of the actions
described above within the time periods, required above, rather than as
otherwise provided in the Credit Documents); PROVIDED that (x) to the extent
any representation and warranty would not be true because the foregoing
actions were not taken on the Second Restatement Effective Date or the ASHS
Acquisition Date, as the case may be, the respective representation and
warranty shall be required to be true and correct in all material respects at
the time the respective action is taken (or was required to be taken) in
accordance with the foregoing provisions of this Section 13.19 and (y) all
representations and warranties relating to the Collateral Documents shall be
required to be true immediately after the actions required to be taken by
Section 13.19 have been taken (or were required to be taken). The acceptance
of the benefits of the Loans shall constitute a representation, warranty and
covenant by the Borrower to each of the Banks that the actions required
pursuant to this Section 13.19 will be, or have been, taken within the
relevant time periods referred to in this Section 13.19 and that, at such
time, all representations and warranties contained in this Credit Agreement
and the other Credit Documents shall then be true and correct without any
modification pursuant to this Section 13.19. The parties hereto acknowledge
and agree that the failure to take any of the actions required above, within
the relevant time periods required above, shall give rise to an immediate
Event of Default pursuant to this Agreement.

                  13.20 ADDITIONS OF NEW BANKS. On and as of the occurrence
of the Second Restatement Effective Date in accordance with Section 13.10
hereof, each New Bank shall become a "Bank" under, and for all purposes of,
this Agreement and the other Credit Documents.
