NOTE 1 - BASIS OF PRESENTATION

         The accompanying consolidated financial statements are unaudited. These
statements have been prepared in accordance with the rules and regulations of
the Securities and Exchange Commission and should be read in conjunction with
the Company's consolidated financial statements and notes thereto for the year
ended December 31, 1997 included in its Form 10-K filed with the Securities and
Exchange Commission on April 15, 1998. Certain information and note disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to such
rules and regulations. In the opinion of Company management, the consolidated
financial statements for the unaudited interim periods presented include all
adjustments, consisting only of normal recurring adjustments, necessary to
present a fair statement of the results for such interim periods.

         Certain prior period amounts have been reclassified to conform to the
current period presentation.

         Operating results for the three and nine month periods ended September
30, 1998 are not necessarily indicative of the results that may be expected for
a full year or any portion thereof.

NOTE 2 - INCOME TAXES

         The provision for income taxes is based on the Company's estimated
effective income tax rate for 1998. At December 31, 1997, the Company had net
operating loss carryforwards for federal income tax purposes of approximately
$10,000. The Company will only be able to use the net operating loss
carryforwards against future taxable earnings of the Company. In addition, as
specified in the Internal Revenue Code, the Company's ability to use certain of
the net operating loss carryforwards is limited as they were acquired by the
Company in a purchase of the stock of other companies. The carryforwards expire
in varying amounts through 2012. A valuation reserve has been established
against the potential future benefit of the net operating loss carryforwards and
other deferred tax assets.

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

             (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)


         The Company provides managed behavioral health services through full
and shared risk arrangements with employers and managed care organizations,
employee assistance programs and other programs, including third party clinical
case management and claims adjudication.

         In December 1997, the Company announced its plans to sell and divest
its outpatient behavioral health group practice operations . The Company entered
into an agreement to sell substantially all of the assets of the outpatient
behavioral practice business (the "Sale"), except for practices located in the
Western region of the United States which the Company has sold or shut down. The
Sale was completed effective May 18, 1998 and resulted in the divestiture by the
Company of substantially all the assets and business of the Company's outpatient
behavioral health practices. As of December 31, 1997, the outpatient behavioral
health practice business accounted for approximately eight-four percent (84%) of
the assets of the Company (before the impact of the write down of assets held
for sale and the impact of the restructuring charge); and for the year ended
December 31, 1997, approximately eighty-three percent (83%) of the Company's net
revenues. As a result of the Sale, the Company is significantly smaller in terms
of revenues and assets.

         In July 1998, the Company announced it received approval from its
shareholders to change the name of the Company from Apogee, Inc. (AMEX: APG) to
Integra, Inc. (AMEX: IGR). The new name reflects the Company's decision to focus
on the successful Integra behavioral managed care operation, which the Company
believes is well established and respected in the behavioral health market.

Sale and Divestiture of Outpatient Business

         On December 26, 1997, the Company entered into an Agreement of Purchase
and Sale (the "Purchase Agreement") with PsychPartners MidAtlantic, Inc.,
PsychPartners, Inc., and PsychPartners, LLC (collectively "PsychPartners" or the
"Purchasers"). Pursuant to the Purchase Agreement, the Company agreed to sell to
the Purchasers substantially all of the assets and business of the Company's
outpatient behavioral healthcare business, which consisted of (i) all of the
capital stock of one of the subsidiaries of the Company operating two outpatient
behavioral health practices and (ii) substantially all of the assets relating to
20 of the Company's outpatient behavioral health practices (the 22 practices are
collectively, the "Practices").

                                  Page 10 of 20
<PAGE>   11
On May 14, 1998, at a Special Meeting of the Shareholders of the Company, the
shareholders approved and adopted the terms of the Purchase Agreement with
PsychPartners. Effective on May 18, 1998, the Company closed the Sale. The
purchase price paid at closing consisted of: (a) $26,400 in cash, (b) a warrant
contingently issuable to purchase 230,000 Common Units of PsychPartners, L.L.C.
at a purchase price of $.05 per Common Unit and (c) the assumption of certain
liabilities. The purchase price is subject to adjustment if the cash, accounts
receivable, deposits and prepaid expenses of the Practices are less than the
liabilities and future contingent payment obligations of the Practices. 

TOTAL NET REVENUES 

Patient Service Revenue

         Patient service revenue is reported when earned at time of service at
the estimated amounts to be realized through payments from patients, third party
payors and others for services rendered. Third party reimbursement is initially
billed at "usual, customary and reasonable" market rates. Aggregate billings are
adjusted when recorded to reflect the estimated amounts realizable from third
party payors based on the Company's historical experience and contractual rates
established with the payors. Patient service revenue represents billings of the
Company's operations other than its behavioral managed care division, which are
principally comprised of the outpatient group practice business and long-term
care behavioral health business.

         Patient service revenue for the three and nine month periods ended
September 30, 1998 decreased significantly from the same periods of the prior
year. This decrease is essentially a result of the impact of operations sold to
PsychPartners and of Western region operations which have been sold or closed.

Premium Revenue

         Premium revenue pertains to the Company's managed behavioral care
operations which maintain a portfolio of agreements with managed care
organizations and corporations to provide inpatient and outpatient behavioral
health services. Revenues are primarily generated by capitated managed
behavioral health and employee assistance programs. The fees are defined by
contract and are primarily calculated on a fixed per-member per-month fee.
Revenues under these contracts are recorded in the month for which the member is
entitled to services. Generally, these membership contracts are on a one to
three year basis subject to cancellation by either party without cause at any
time with thirty to ninety days written notice.

         The Company estimates the cost of providing services under these
agreements, including a reserve for services incurred, but not reported, based
upon authorized services, past claim payment experience for member groups and
other facts. The Company typically does not subcapitate the risk of providing
services under these contracts, but the Company arranges discounted
fee-for-service rates with independent inpatient and outpatient behavioral
health providers, which the Company manages. In certain markets, as part of its
provider network, the Company utilizes certain of the outpatient behavioral
health practices which were sold to PsychPartners. The Company anticipates that
in these markets where practicable, it will continue to utilize these outpatient
behavioral health practices at the existing or comparable rates which it
believes are at fair market. The Company believes that there is a ready supply
of service providers in these markets, and accordingly, the Company is not
dependent on these outpatient behavioral health practices for the delivery of
service to their contracts.

                                  Page 11 of 20
<PAGE>   12
         Under capitated contracts, the Company is responsible for ensuring
appropriate access to care and bears the risk for utilization levels and pricing
of the cost of services performed under these contracts. The Company believes
the future revenues under these contracts will exceed the costs of services it
will be required to provide under the terms of the contracts. An underestimation
in the utilization or price of services for these contracts could result in
material losses to the Company. Historically, Integra has managed these
capitated contracts profitably. The Company maintains no re-insurance against
the risk of loss under these contracts.

         Premium revenues for the three and nine month periods ended September
30, 1998 increased from the same periods of the prior year as a result of new
contracts for capitated managed behavioral health services and employee
assistance programs.

GROSS PROFIT

         Gross profit comprises net revenues less personnel, field management,
facility and other costs and expenses directly associated with the delivery of
services. Gross profit decreased significantly for the three and nine month
periods ended September 30, 1998 from the comparable periods last year. This
decrease is primarily a result of the impact of operations which were sold to
PsychPartners on May 18, 1998 or which were discontinued in conjunction with the
Company's restructuring in the fourth quarter of 1997.

SELLING AND ADMINISTRATIVE EXPENSES

         Selling and administrative expenses are primarily comprised of
corporate office, divisional management, sales and administration. Selling and
administrative expenses decreased to $902 for the three months ended September
30, 1998 from $2,668 for the same period in 1997, and to $5,294 for the nine
months ended September 30, 1998 from $7,756 for the same period in 1997. The
decrease is essentially a result of the impact of operations sold to
PsychPartners and of Western region operations which have been sold or closed.

PROVISION OF DOUBTFUL ACCOUNTS

         The provision for doubtful accounts decreased for the three and nine
month periods ended September 30, 1998 from the comparable period in 1997. The
decrease results from the Sale and discontinuation of the outpatient operations.

INTEREST EXPENSE - RELATED PARTIES

         In order to provide for additional financing if the sale did not occur,
the Company entered into an agreement with certain investment partnerships (the
"Investment Partnerships"), which are significant stockholders of the Company
and are managed by Foster Management Company, an affiliated party, to obtain
their commitment to guarantee an additional $7,000 of financing. This additional
financing amount represented the Company's estimated additional cash needs
during 1998 for contingent payments, seller notes and for restructure related
activities.

                                  Page 12 of 20
<PAGE>   13
Under the terms of the agreement, in return for their guaranty the Investment
Partnerships were to receive the following: (i) a commitment fee of 2% of the
guaranteed amount; (ii) a draw down fee of 2% on Bank borrowings in excess of
$15,000; (iii) an unused commitment fee of 1/2% per annum; and (iv) warrants to
purchase 400,000 shares of common stock of the Company at a price of $0.05 per
share (the "Integra Warrants") or, in the event the Sale was not consummated, a
transaction fee of $3,500 payable on April 30, 1999. With the Sale completed,
the cost to the Company of this guarantee was $1,020 of which $140 was paid in
cash to the Investment Partnerships. The remaining portion represents a non-cash
charge of approximately $880, which is the difference between the exercise price
of the Integra Warrant and the fair market value of the underlying common stock
of the Company on the closing date of the Sale to PsychPartners. These charges,
which are non-recurring in nature, have been recorded in the Company's results
of operations for the quarter ended June 30, 1998.

INTEREST (INCOME) EXPENSE

         The Company recorded interest income of $77 for the three months ended
September 30, 1998 due primarily to remaining proceeds from the Sale. Interest
expense decreased to $529 for the nine months ended September 30, 1998 from
$1,061 for the same period in 1997 due primarily to the pay down of bank debt
with proceeds from the Sale.

OTHER MATTERS

         During 1996, certain of the Company's Medicare Part B and related
co-insurance billings previously submitted were selected for review by the
Office of the Inspector General of the Department of Health and Human Services
("OIG") and the Department of Justice ("DOJ"). The Company was notified by the
DOJ that the review is a civil matter relating to billings for services to
Medicare patients in long-term care facilities in the State of Florida during
the period from approximately January 1994 through mid-1995. In October 1998,
the Company executed a final settlement agreement with the DOJ and OIG, which
resolved all of the OIG's civil claims against the Company relating to this
matter. Terms of the settlement included a repayment of approximately $3,000.
This amount was fully accrued as of September 30, 1998.

         In March 1998, the Company received notification that the Medicare
intermediary in California has completed a post payment medical review of
billings previously submitted and paid between 1990 and 1994. Based on the
results of their review, the intermediary has requested a refund of
approximately $1,200. Payment for services were denied primarily on the basis of
medical necessity and incomplete documentation. The Company has not yet
completed its review of the intermediary 's findings, but anticipates requesting
an administrative hearing. The Company has fully reserved for the above amount.

         In April 1998, the Company received notice from the office of the
Attorney General of New York State that the New York Medicaid billings of one of
the operations with which it has an Administrative Services Agreement would be
audited. Due to the preliminary nature of the review, the Company cannot predict
when the audit will be completed, its ultimate outcome or its potential impact
of earnings. The Company believes that the outcome of the audit, including
repayments, if any, should not have a material adverse effect on the Company's
results of operations or financial condition.

                                  Page 13 of 20
<PAGE>   14
         Although management believes that the reserves established for the
above matters are sufficient, it is possible that the final resolution of these
matters may exceed the established reserves by an amount which could be material
to the Company's results of operations. The Company does not believe the
ultimate outcome of these matters will have a material adverse effect on the
Company's overall financial condition, liquidity or operations. 

Liquidity and Capital Resources

         Net cash used in operations was $2,463 for the nine months ended
September 30, 1998, compared to net cash provided by operations of $1,782 for
the same period in the prior year. Cash and cash equivalents increased to $4,210
at September 30, 1998 from $2,154 at December 31,1997 due to the remaining
proceeds of the Sale.

         At September 30, 1998, the Company had a working capital deficit of
($6,550). This deficit is primarily attributable to the current classification
of accrued liabilities of $7,322 which pertain to the Company's sale of and exit
from the outpatient behavioral group practice business and reserves established
for its long-term care operations which were discontinued in 1996. Although
these amounts are classified as current due to their nature, the Company does
not expect that all of these amounts will require payment within the next twelve
months.

         In October 1998, the Company entered into an agreement with PNC Bank
(the "Bank") to establish a revolving Credit Facility ("Credit Facility") for up
to a maximum of $10,000. Borrowings availability under this Credit Facility are
primarily based on the Company's earnings before interest, income taxes,
depreciation and amortization, subject to various financial and non-financial
covenants; and secured by substantially all of the assets of the Company.
Borrowings under this facility bear a variable rate interest ranging between the
Bank's prime rate plus 0.25% to 1.0% or LIBOR plus 1.75% to 2.50%. The proceeds
of this Credit Facility are available for future acquisitions, working capital
and general corporate purposes. There are currently no outstanding borrowings
under the Credit Facility.

         The Company believes that the cash flow generated by the Company's
operations together with its existing cash and Credit Facility will be
sufficient to meet the Company's current cash requirements.

         The Company's current ratio, working capital and debt to equity ratio
are set forth below for the dates indicated:

Inflation

         A significant portion of the Company's operating expenses have been
subject to inflationary increases, including clinical and administrative
salaries and rent expense. Based on management's assessment, the Company has
historically been unable to substantially offset inflationary increases through
price increases. The Company believes it has somewhat mitigated the effect by
expanding services and increasing operating efficiencies. There can be no
assurance that the Company will be able to offset future inflationary increases
in expenses, if any, which would result in a dilutive impact on the Company's
future earnings.

YEAR 2000 ISSUES



         The year 2000 problem is primarily the result of two potential
malfunctions that could have an impact on the Company's systems and equipment.
The first problem arises due to computers being programmed to use two rather
than four digits to define the applicable year.  The second problem arises in
embedded chips where microchips and microcontrollers have been designed using
two rather than four digits to define the applicable year.  Certain of the
Company's computers programs, and building infrastructure components (e.g.
alarm systems and HVAC systems) are date sensitive and may recognize a date
using "00" as the year 1900 rather than the year 2000.  If uncorrected, the
problems could result in computer system and program failures or could result
in a disruption of business operations or that could affect the Company's
ability to deliver service.

         The Company has undertaken a program to inventory, access and correct,
replace or otherwise address its computer hardware, systems software, business
software, and telecommunication equipment.  The Company has implemented a
program to contact vendors, analyze information provided, and to remediate,
replace or otherwise address products that may pose a material Year 2000
impact.  The Company anticipates completion, in all material respects of the
information technology infrastructure portion of its program by June 1999.  The
Company believes that the cost to correct its information technology
infrastructure will not be material and will not require an investment in
capital assets significantly in excess of the Company's historical levels.

     The Company presently believes that with modifications to existing
software or the installation of upgraded software the Year 2000 will not pose
material operational problems for its computer systems and information
technology infrastructure.  However, if such modifications or upgrades are not
accomplished in a timely manner, Year 2000 related failures may present a
material adverse impact on the operations of the Company.

         Due to the potentially far-reaching affects of the Year 2000 problem,
the Company believes it is also important to obtain an understanding of its key
payors and vendors readiness for Year 2000 issues.  To this extent, the Company
has initiated communications with its major customers.  The Company relies on
timely reimbursement, as well as member eligibility and benefit data often
through the use of electronic data interfaces.  Failure of these third party
systems could have a material adverse affect on the Company's results of
operations.  The Company also has initiated communications with its critical
suppliers and vendors (i.e. those suppliers and vendors whose products and
services are essential for day to day operations) to assure their continued
operation through the Year 2000. The Company is continuing its efforts to
obtain such assurances from all critical suppliers and vendors. Failure of
these third parties could have material impact on operations and/or the ability
to provide behavioral health services.


CAUTIONARY STATEMENT

         Matters discussed above contained forward-looking statements that are
based on the Company's estimates, assumptions and projections. Major factors
which could cause results to differ materially from those expected by management
include the timing and nature of reimbursement changes, the nature of changes in
laws and regulations that govern various aspects of the Company's business, new
criteria adopted to determine medical necessity for behavioral health services,
the outcome of post-payment reviews of the Company's billings to Medicare
patients in long-term care facilities, year 2000 issues, pricing of managed
care and other third party contracts, the utilization and cost of services
under the Company's capitated contracts, the direction and success of
competitors, management retention and unanticipated market changes.

PART II

ITEM 1 - LEGAL PROCEEDINGS

         From time to time, the Company is a party to certain claims, suits and
complaints which arise in the ordinary course of business. In March 1998, the
Company received notification that the Medicare intermediary in California has
completed a post payment medical review of billings previously submitted and
paid between 1990 and 1994. Based on the results of their review, the
intermediary has requested a refund of approximately $1,200. Services were
denied primarily on the basis of medical necessity and incomplete documentation.
The Company has not yet completed its review of the intermediary's findings, but
anticipates requesting an administrative hearing. The Company fully reserved for
the above amount.

         In April 1998, the Company received notice from the office of the
Attorney General of New York State that the New York Medicaid billings of one of
the operations with which it has an Administrative Services Agreement would be
audited. Due to the preliminary nature of the review, the Company can not
predict when the audit will be completed, its ultimate outcome or its potential
impact of earnings, but believes the outcome of the audit, including repayments,
if any, should not have a material adverse effect on the Company's results of
operations or financial condition.

to time and the (ii) the sum of all Revolving Credit Loans outstanding plus the
Letters of Credit Outstanding.

to time upon five (5) Business Days' prior written notice to the Bank to
permanently reduce, in a minimum amount of $1,000,000 of principal, or terminate
the Revolving Credit Commitment without penalty or premium, except as

by such Revolving Credit Loan.

of the Expiration Date by written notice to the Bank, and the Bank agrees to
respond to the Borrowers' request for an extension within thirty (30) calendar
days; provided, however, that the failure of the Bank to respond within such
time period shall not in any manner constitute an 


                                       20
<PAGE>   24
agreement by the Bank to extend the Expiration Date. If the Bank elects to

Borrower or Borrowers in accordance with Section 2.5, the Borrowers shall
internally account on an individual Borrower basis for the use of the proceeds
of the Revolving Credit Loans by each Borrower.

"Letters of Credit"); provided, however, that each Letter of Credit shall have a
maximum maturity of twelve (12) months from the date of issuance and shall in no
event expire later than one Business Day prior to the Expiration Date; provided,
further, however, that in no event shall (i) the aggregate undrawn face amount
of the Letters of Credit issued to all of the Borrowers pursuant to this Section
2.9 exceed, at any one time, $1,000,000; or (ii) the aggregate outstanding
principal balance of the Revolving Credit Loans made to the Borrowers pursuant
to Section 2.1 plus the Letters of Credit Outstandings exceed at any one time,
the Revolving Credit Commitment.

                           (b) The Borrower shall pay (i) to the Bank a fee (the

preceding clauses (i) and (ii) shall be computed on the daily average Letters of
Credit Outstanding and shall be payable quarterly in arrears commencing with the
first Business Day of each January, April, July and October following issuance

payable with respect to the Letters of Credit as the Bank may generally charge
or incur from time to time in connection with the issuance, maintenance,

Credit Loans from the Bank and shall bear interest initially at the Base Rate

contained in, Section 4.1.

                           (d) The Borrowers, jointly and severally, agree to be
bound by the terms of the Bank's application and/or agreement for Letters of
Credit (including the Bank's standard form application and reimbursement
agreements and documentation) and the Bank's written regulations and customary
practices relating to Letters of Credit, though such interpretation may be
different from the Borrowers' own, and it is understood and agreed that, except
in the case of gross negligence or willful misconduct, the Bank shall not be
liable for any error, negligence and/or mistakes, whether of omission or
commission, in following the Borrowers' instructions or those contained in the
Letters of Credit or any modifications, amendments or supplements thereto.

Loans comprising any Borrowing Tranche provided that there shall not be at any
one time outstanding more than seven (7) Borrowing Tranches in the aggregate
comprising the Revolving Credit Euro-Rate Portion. The Bank's determination of a

Consolidated Cash Flow from Operations. Such ratio shall be computed as of the
end of each fiscal quarter, with the calculation of Consolidated Cash Flow from
Operations made as provided in the definition of such term in Section 1.1.
Adjustments to interest attributable to a change in such ratio shall be
effective (a) on the Delivery Date for the Borrower's consolidated financial
statements for such quarter if the applicable interest rate is to be increased
and (b) on the later of the Delivery Date for such financial statements or the
date on which such financial statements are actually delivered to the Bank if
the applicable interest rate is to be decreased.

                           (b) Rate Quotations. Integra, as agent for the
Borrowers, may call the Bank on or before the date on which a Revolving Credit
Loan Request is to be delivered to receive an indication of the rates then in
effect, but it is acknowledged that such projection shall not be binding on the
Bank nor affect the rate of interest which thereafter is actually in effect when
the election is made.

                  4.2      Interest Periods.

                  At any time when Integra, as agent for the Borrowers, shall
select, convert to or renew a Revolving Credit Euro-Rate Option, Integra shall
notify the Bank thereof at least three (3) Business Days prior to the effective
date of such Revolving Credit Euro-Rate Option by delivering a Revolving Credit
Loan Request. The notice shall specify an interest period during which such
Interest Rate Option shall apply, such periods to be one, two, three or six
months ("Euro-Rate Interest Period"), provided, that:

                           (a) any Euro-Rate Interest Period which would
otherwise end on a date which is not a Business Day shall be extended to the
next succeeding Business Day unless such Business Day falls in the next calendar
month, in which case such Euro-Rate Interest Period shall end on the next
preceding Business Day;

                           (b) any Euro-Rate Interest Period which begins on the
last day of a calendar month for which there is no numerically corresponding day
in the subsequent calendar month during which such Euro-Rate Interest Period is
to end shall end on the last Business Day of such subsequent month;

                           (c) Revolving Credit Euro-Rate Portion for each
Euro-Rate Interest Period shall be in integral multiples of $50,000 and not less
than $300,000;

                           (d) Integra shall not select, convert to or renew a
Euro-Rate Interest Period for any portion of the Revolving Credit Loans that
would end after the Expiration Date; and

                           (e) in the case of the renewal of a Revolving Credit
Euro-Rate Option at the end of a Euro-Rate Interest Period, the first day of the
new Euro-Rate Interest Period shall be the last day of the preceding Euro-Rate
Interest Period, without duplication in payment of interest for such day.

                  4.3      Interest After Default.

                  To the extent permitted by Law, upon the occurrence and during
the continuation of an Event of Default, any principal, interest, fee or other
amount payable hereunder shall bear interest for each day thereafter until paid
in full (before and after judgment) at a rate per annum 



                                       24
<PAGE>   28
which shall be equal to two hundred (200) basis points (2% per annum) above the
rate of interest otherwise applicable with respect to such amount or two hundred
(200) basis points (2% per annum) above the interest rate calculated pursuant to
Section 4.1(a)(i) (in respect of the Base Rate) if no rate of interest is
otherwise applicable. Each Borrower acknowledges that such increased interest
rate reflects, among other things, the fact that such Revolving Credit Loans or
other amounts have become a substantially greater risk given their default
status and that the Bank is entitled to additional compensation for such risk.

                  4.4      Euro-Rate Unascertainable.

                           (a) If on any date on which a Euro-Rate would
otherwise be determined, the Bank shall have determined (which determination
shall be conclusive absent manifest error) that:

                                    (i) adequate and reasonable means do not
exist for ascertaining such Euro-Rate, or

                                    (ii) a contingency has occurred which
materially and adversely affects the secondary market for negotiable
certificates of deposit maintained by dealers of recognized standing relating to
the London interbank market relating to the Euro-Rate, or

                           (b) if at any time the Bank shall have determined
(which determination shall be conclusive absent manifest error) that:

                                    (i) the making, maintenance or funding of
any Revolving Credit Loan to which a Revolving Credit Euro-Rate Option applies
has been made impracticable or unlawful by compliance by the Bank in good faith
with any Law or any interpretation or application thereof by any Official Body
or with any request or directive of any such Official Body (whether or not
having the force of Law), or

                                    (ii) such Revolving Credit Euro-Rate Option
will not adequately and fairly reflect the cost to such Bank of the
establishment or maintenance of any such Revolving Credit Loan, or

                                    (iii) after making all reasonable efforts
that deposits of the relevant amount in Dollars for the relevant Euro-Rate
Interest Period for a Revolving Credit Loan to which a Revolving Credit
Euro-Rate Option applies, respectively, are not available to the Bank at the
effective cost of funding a proposed Revolving Credit Loan to which the
Revolving Credit Euro-Rate Option applies in the London interbank market, then,
in the case of any event specified in subsection (a) above, the Bank shall
promptly so notify Integra, as agent for the Borrowers, and in the case of an
event specified in subsection (b) above, the Bank shall promptly endorse a
certificate to such notice as to the specific circumstances of such notice and
the Bank shall promptly send copies of such notice and certificate to Integra,
as agent for the Borrowers. Upon such date as shall be specified in such notice
(which shall not be earlier than the date such notice is given) the obligation
of the Bank to allow Integra, as agent for the Borrowers, to select, convert to
or renew a Revolving Credit Euro-Rate Option shall be suspended until the Bank
shall 



                                       25
<PAGE>   29
have later notified Integra, in such capacity, of the Bank's determination
(which determination shall be conclusive absent manifest error) that the
circumstances giving rise to such previous determination no longer exist. If at
any time the Bank makes a determination under subsection (a) or (b) of this
Section 4.4 and Integra has previously notified the Bank of its selection of,
conversion to or renewal of a Revolving Credit Euro-Rate Option and such
Interest Rate Option has not yet gone into effect, such notification shall be
deemed to provide for selection of, conversion to or renewal of the Revolving
Credit Base Rate Option otherwise available with respect to such Revolving
Credit Loans (except that the interest thereon shall be the Base Rate plus
 .25%). If the Bank notifies Integra of a determination under subsection (b) of
this Section 4.4, the Borrowers shall, subject to the Borrowers' indemnification
obligations under Section 5.4(b), as to any Revolving Credit Loan of the Bank to
which a Revolving Credit Euro-Rate Option applies, on the date specified in such
notice either convert such Revolving Credit Loan to the Revolving Credit Base
Rate Option otherwise available with respect to such Revolving Credit Loan
(except that the interest thereon shall be the Base Rate plus .25%) or prepay
such Revolving Credit Loan in accordance with Section 5.3 hereof. Absent due
notice from Integra of conversion or prepayment, such Revolving Credit Loan
shall automatically be converted to the Revolving Credit Base Rate Option
otherwise available with respect to such Revolving Credit Loan upon such
specified date.

                  4.5      Selection of Interest Rate Options.

                  If Integra, as agent for the Borrowers, fails to select a
Euro-Rate Interest Period in accordance with the provisions of Section 4.2 in
the case of renewal of the Revolving Credit Euro-Rate Portion, Integra shall be
deemed to have converted such Revolving Credit Loan or portion thereof to the
Revolving Credit Euro-Rate Option with a three month Euro-Rate Interest Period,
commencing upon the last day of the prior Euro-Rate Interest Period.

                  5.1      Payments.

                  All payments and prepayments to be made in respect of
principal, interest, Closing Fee, Letter of Credit Fees or other fees or amounts
due from the Borrowers hereunder shall be payable prior to 2:00 P.M. (Pittsburgh
time) on the date when due without presentment, demand, protest or notice of any
kind, all of which are hereby expressly waived by the Borrowers, and without
setoff, counterclaim or other deduction of any nature, and an action therefor
shall immediately accrue. Such payments shall be made to the Bank at its
Principal Office with respect to the Revolving Credit Loans in U.S. Dollars and
in immediately available funds. The Bank's statement of account, ledger or other
relevant record shall, in the absence of manifest error, be conclusive as the
statement of the amount of principal of and interest on the Revolving Credit
Loans and other amounts owing under this Agreement and shall be deemed an
"account stated."

                  5.2      Interest Payment Dates.

                  Interest on Revolving Credit Loans to which the Revolving
Credit Base Rate Option applies shall be due and payable in arrears on the first
Business Day of each April, July, October and January, after the date hereof,
and on the Expiration Date or upon acceleration of the Revolving Credit Note.
Interest on Revolving Credit Loans to which the Revolving Credit Euro-Rate
Option applies shall be due and payable on the last day of each Euro-Rate
Interest Period. The Borrowers authorize the Bank to debit with two Business
Days' prior notice (but without prior notice if there exists a Potential Default
or Event of Default) any or all amounts due hereunder, when due, from accounts
regularly maintained with the Bank.

                  5.3      Prepayments.

                           (a) Voluntary Prepayments. Each Borrower shall have
the right at its option from time to time to prepay the Revolving Credit Loans
in whole or part without premium or penalty (except as provided in Section 5.4
hereof):

                                    (i) at any time with respect to any
Revolving Credit Loan to which the Revolving Credit Base Rate Option applies,

                                    (ii) on the last day of the applicable
Euro-Rate Interest Period with respect to Revolving Credit Loans to which a
Revolving Credit Euro-Rate Option applies, or

                                    (iii) on the date specified in a notice by
the Bank pursuant to Section 4.4(b) hereof with respect to any Revolving Credit
Loan to which a Revolving Credit Euro-Rate Option applies.

                  Whenever a Borrower desires to prepay any part of the
Revolving Credit Loans, it shall cause Integra, as its agent, to provide a
prepayment notice to the Bank at least one (1) Business Day prior to the date of
prepayment of Revolving Credit Loans setting forth the following information:

                                    (x) the date, which shall be a Business Day,
on which the proposed prepayment is to be made; and

                                    (y) the total principal amount of such
prepayment, which shall not be less than $50,000.

                  All prepayment notices shall be irrevocable unless otherwise
agreed to by the Bank. The principal amount of the Revolving Credit Loans for
which a prepayment notice is given, together with interest on such principal
amount except with respect to Revolving Credit Loans to which the Revolving
Credit Base Rate Option applies, shall be due and payable on the date specified
in such prepayment notice as the date on which the proposed prepayment is to be
made. Unless otherwise specified by Integra on behalf of such Borrower with
respect to prepayments of the Revolving Credit Euro-Rate Portion of the
Revolving Credit Loans permitted 



                                       27
<PAGE>   31
under (ii) or (iii) above, all prepayments shall be applied first to the
Revolving Credit Base Rate Portion of such Revolving Credit Loans, as the case
may be, and then to the Revolving Credit Euro-Rate Portion of such Revolving
Credit Loans, subject to Section 5.4 hereof.

                           (b) Mandatory Payments. Within thirty (30) Business
Days of any sale of assets, the Revolving Credit Commitment shall automatically
be reduced by an amount equal to the net after-tax proceeds of such sale (as
estimated in good faith by Integra), and the Borrowers shall make payments of
principal to the extent the principal amount of the Revolving Credit Loans and
Letter of Credit Outstandings together exceed the Revolving Credit Commitment as
so reduced, together with accrued interest on such principal amount except that
with respect to sales of assets made at any time after the Closing Date and
generating net proceeds not exceeding $2,000,000 in the aggregate, the Borrowers
may re-invest net proceeds in business assets used in the normal course of the
Borrowers' business provided that such assets are or become within thirty (30)
days after the underlying asset sale Collateral as to which the Bank has a Prior
Security Interest.

                  5.4      Additional Compensation in Certain Circumstances.

                           (a) Increased Costs or Reduced Return Resulting From
Taxes, Reserves, Capital Adequacy Requirements, Expenses, Etc. If any Law,
guideline or interpretation or any change in any Law, guideline or
interpretation or application thereof by any Official Body charged with the
interpretation or administration thereof or compliance with any request or
directive (whether or not having the force of Law) of any central bank or other
Official Body:

                                    (i) subjects the Bank to any tax or changes
the basis of taxation with respect to this Agreement, the Revolving Credit Note,
the Revolving Credit Loans or payments by any Borrower of principal, interest,
or other amounts due from any Borrower hereunder or under the Revolving Credit
Note (except for taxes on the net income of the Bank),

                                    (ii) imposes, modifies or deems applicable
any reserve, special deposit or similar requirement against credits or
commitments to extend credit extended by, or assets (funded or contingent) of,
deposits with or for the account of, or other acquisitions of funds by, the
Bank, or

                                    (iii) imposes, modifies or deems applicable
any capital adequacy or similar requirement (A) against assets (funded or
contingent) of, or letters of credit, other credits or commitments to extend
credit extended by, the Bank, or (B) otherwise applicable to the obligations of
the Bank under this Agreement, and the result of any of the foregoing is to
increase the cost to, reduce the income receivable by, or impose any expense
(including loss of margin) upon the Bank or its parent with respect to this
Agreement, the Revolving Credit Note or the making, maintenance or funding of
any part of the Revolving Credit Loans (or, in the case of any capital adequacy
or similar requirement, to have the effect of reducing the rate of return on the
capital of the Bank or its parent, taking into consideration the Bank's
customary policies with respect to capital adequacy) by an amount which the Bank
in its sole discretion deems to be material, the Bank shall from time to time
notify the Borrowers of the amount determined in 



                                       28
<PAGE>   32
good faith (using any averaging and attribution methods employed in good faith)
by the Bank (which determination shall be conclusive absent manifest error) to
be necessary to compensate the Bank for such increase in cost, reduction of
income or additional expense. Such notice shall set forth in reasonable detail
the basis for such determination. Such amount shall be due and payable by the
Borrowers, jointly and severally, to the Bank ten (10) Business Days after such
notice is given. For purposes of this Section 5.4(a), in calculating the amount
necessary to compensate the Bank for any such increase in cost, reduction of
income or additional expense, the Bank shall calculate the amount payable to it
in a manner consistent with the manner in which it shall calculate similar
compensation payable to it by other borrowers in the industry of the Borrowers
having provisions in their credit agreements comparable to this Section 5.4(a).

                           (b)      Indemnity.

                  In addition to the compensation required by subsection (a) of
this Section 5.4, the Borrowers, jointly and severally, shall indemnify the Bank
against all liabilities, losses or expenses (including loss of margin, any loss
or expense incurred in liquidating or employing deposits from third parties and
any loss or expense incurred in connection with funds acquired by the Bank to
fund or maintain Revolving Credit Loans subject to the Revolving Credit
Euro-Rate Option) which the Bank sustains or incurs as a consequence of any:

                                    (i) payment, prepayment, conversion or
renewal of any Revolving Credit Loan to which the Revolving Credit Euro-Rate
Option applies on a day other than the last day of the corresponding Euro-Rate
Interest Period (whether or not such payment or prepayment is mandatory,
voluntary or automatic and whether or not such payment or prepayment is then
due),

                                    (ii) attempt by the Borrowers to revoke
(expressly, by later inconsistent notices or otherwise) in whole or part any
notice relating to Revolving Credit Loan Requests under Section 2.5, a Euro-Rate
Interest Period designated under Section 4.2 or prepayments under Section 5.3,
or

                                    (iii) default by any Borrower in the
performance or observance of any covenant or condition contained in this
Agreement or any other Loan Document, including without limitation any failure
of any Borrower to pay when due (by acceleration or otherwise) any principal,
interest, or any other amount due hereunder.

                  If the Bank sustains or incurs any such loss or expense it
shall from time to time notify the Borrowers of the amount determined in good
faith by the Bank (which determination shall be conclusive absent manifest error
and may include such assumptions, allocations of costs and expenses and
averaging or attribution methods as the Bank shall deem reasonable) to be
necessary to indemnify the Bank for such loss or expense. Such notice shall set
forth in reasonable detail the basis for such determination. Such amount shall
be due and payable by the Borrowers, jointly and severally, to the Bank ten (10)
Business Days after such notice is given.

                         REPRESENTATIONS AND WARRANTIES

                  6.1      Representations and Warranties.

                  Each Loan Party represents and warrants to the Bank as
follows:

                           (a) Organization and Qualification. Each of the Loan
Parties is a corporation, partnership, limited liability company or business
trust, duly organized, validly existing and, except as set forth on Schedule
6.1(a), in good standing under the laws of its respective jurisdiction of
organization; each Loan Party has the corporate or partnership power (as the
case may be) to own or lease its respective properties and to engage in the
business it presently conducts or proposes to conduct; and each Loan Party is
duly qualified and in good standing in each jurisdiction where the property
owned or leased by it or the nature of the business transacted by it or both
makes such licensing or qualification necessary, except where the failure to be
so licensed or qualified would not cause or constitute a Material Adverse
Change.

                           (b) Capitalization and Ownership. All of the issued
and outstanding shares of authorized capital stock of Integra have been validly
issued and are fully paid and nonassessable.

                           (c) Subsidiaries; Dormant Subsidiaries.

                                    (i) Schedule 6.1(c) attached hereto states
the name of each Subsidiary of Integra, its jurisdiction of organization, and
with respect to each Restricted Subsidiary, its authorized capital stock and the
issued and outstanding shares of each Restricted Subsidiary (referred to herein
collectively as the "Subsidiary Shares") and the owners thereof if it is a
partnership. Integra has good and marketable title to all of the Subsidiary
Shares it purports to own, free and clear in each case of any Lien, except for
Liens in favor of the Bank, and each other Loan Party has good and marketable

validly issued. All Subsidiary Shares are fully paid and nonassessable. Except
as set forth on Schedule 6.1(c), there are no options, warrants or other rights
outstanding to purchase any such Subsidiary Shares.

                                    (ii) Each Subsidiary of Integra which is not
a Dormant Subsidiary is a Restricted Subsidiary and is a Loan Party hereunder
and is listed on the signature lines and Schedule 6.1(c), as a Guarantor and a
Borrower. The aggregate total assets of the Dormant Subsidiaries collectively is
less than $150,000 and the aggregate total liabilities of the Dormant
Subsidiaries collectively is less than $150,000.

                           (d) Power and Authority. Each Loan Party has full
corporate or partnership power to enter into, execute, deliver and carry out
this Agreement and the other Loan Documents to which it is a party, to incur the
Indebtedness contemplated by the Loan Documents 



                                       30

and to perform its obligations under the Loan Documents to which it is a party
and all such actions have been duly authorized by all necessary proceedings on
its part.

                           (e) Validity and Binding Effect. This Agreement has
been duly and validly executed and delivered by each Loan Party, and each other
Loan Document, when duly executed and delivered by each respective Loan Party
thereto, will have been duly and validly executed and delivered by such Loan
Parties. This Agreement and each other Loan Document delivered by the Loan
Parties pursuant to the provisions hereof will constitute legal, valid and
binding obligations of the Loan Parties thereto, enforceable against each
respective Loan Party in accordance with their respective terms, except to the
extent that enforceability of any of the foregoing Loan Documents may be limited
by bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforceability of creditors' rights generally or limiting the
right of specific performance or by general equitable principles.

                           (f) No Conflict. Neither the execution and delivery
of this Agreement or the other Loan Documents by the Loan Parties nor the
consummation of the transactions herein or therein contemplated or compliance
with the terms and provisions hereof or thereof by them will conflict with,
constitute a default under or result in any breach of (i) the terms and
conditions of the certificate of incorporation, bylaws or other organizational
documents of any Loan Party, or (ii) any Law or any material agreement or
instrument or order, writ, judgment, injunction or decree to which any Loan
Party is a party or by which it is bound or to which it is subject, or result in
the creation or enforcement of any Lien, charge or encumbrance whatsoever upon
any property (now or hereafter acquired) of any Loan Party (other than Liens
granted under the Loan Documents).

                           (g) Litigation. Except as set forth on Schedule
6.1(g), there are no actions, suits, proceedings or investigations pending or,
to the knowledge of any Loan Party, threatened against any Loan Party at law or
equity before any Official Body which individually or in the aggregate would
constitute a Material Adverse Change including, without limitation, any actions,
suits or proceedings by any Official Body to recover any Medicare or Medicaid
payments from any Loan Party or to otherwise exclude any Loan Party from
participation in any Medicare, Medicaid or similar program. No Loan Party is in
violation of any order, writ, injunction or any decree of any Official Body
which would constitute a Material Adverse Change.

                           (h) Title to Properties. Each of the Loan Parties has
good and marketable title to or valid leasehold interest in all properties,
assets and other rights which it purports to own or lease or which are reflected
as owned or leased on its books and records, free and clear of all Liens and
encumbrances except Permitted Liens. All leases of property are in full force
and effect without the necessity for any consent which has not previously been
obtained upon consummation of the transactions contemplated hereby. As of the
Closing Date, no Loan Party owns any fee interest in real property.

                           (i) Financial Statements.

                           (A) Historical Statements. Integra has delivered to
the Bank copies of its audited consolidated year-end financial statements for
and as of the end of the fiscal year ended December 31, 1997 (the "Annual
Statements") and its unaudited consolidated financial statements for and as of
the fiscal quarter ended June 30, 1998 (the "Interim Statements" and, together
with the Annual Statements, the "Historical Statements"). The Historical
Statements were compiled from the books and records maintained by Integra's
management, fairly present the consolidated financial condition of Integra and
its Subsidiaries as of their dates and the results of operations for the fiscal
periods then ended and have been prepared in accordance with GAAP consistently
applied.

                           (B) Financial Projections. Integra has delivered to
the Bank financial projections of Integra and its Subsidiaries through December
31, 2001 derived from various assumptions of Integra's management (the
"Financial Projections"). The Financial Projections represent a reasonable range
of possible results in light of the history of the business, present and
reasonably foreseeable conditions and the intentions of Integra's management.
The Financial Projections reasonably reflect the liabilities of Integra and its
Subsidiaries upon consummation of the transactions contemplated hereby as of the
Closing Date.

                           (C) Accuracy of Financial Statements. Neither Integra
nor any Subsidiary has any material liabilities, contingent or otherwise, or
material forward or long-term commitments that are not disclosed in the
Historical Statements or in the notes thereto and are required to be disclosed,
and except as disclosed therein there are no unrealized or anticipated losses
from any commitments of Integra or any Subsidiary which are required to be
disclosed. Since June 30, 1998 no Material Adverse Change has occurred.

                           (j) Full Disclosure. Neither this Agreement nor any
other Loan Document, nor any certificate, statement, agreement or other
documents furnished to the Bank in connection herewith or therewith or filed
with the Securities and Exchange Commission (on which the Bank is hereby
entitled to rely), contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained herein
and therein, in light of the circumstances under which they were made, not
misleading.

                           (k) Taxes. All material federal, state, local and
other tax returns required to have been filed with respect to each Loan Party
have been filed and payment or adequate provision has been made for the payment
of all taxes, fees, assessments and other governmental charges which have or may
become due pursuant to said returns or to assessments received except to the
extent that such taxes, fees, assessments and other charges are being contested
in good faith by appropriate proceedings diligently conducted and for which such
reserves or other appropriate provisions, if any, as shall be required by GAAP
shall have been made. There are no agreements or waivers extending the statutory
period of limitations applicable to any federal income tax return of any Loan
Party.

                           (l) Consents and Approvals. No consent, approval,
exemption, order or authorization of, or a registration or filing with any
Official Body or any other Person is 



                                       32
<PAGE>   36
required by any Law or any agreement in connection with the execution, delivery
and carrying out of this Agreement and the other Loan Documents by any Loan
Party, except as listed on Schedule 6.1(l) attached hereto, all of which shall
have been obtained or made on or prior to the Closing Date except as otherwise
indicated on Schedule 6.1(l); provided, however, that it is acknowledged that
consent of health care regulatory authorities issuing any licenses or regulating
any health care facilities may be required if the Bank exercises the rights and
remedies in respect of the Pledged Collateral and such exercise of remedies
results in or constitutes an assignment of any health care license issued by a
health care regulatory authority or constitutes a change of control with respect
to the ownership of a health care facility.

                  (m) No Event of Default; Compliance with Instruments. No event
has occurred and is continuing and no condition exists or will exist after
giving effect to the borrowings to be made on the Closing Date under the Loan
Documents which constitutes an Event of Default or Potential Default. No Loan
Party is in violation of (i) any term of its certificate of incorporation,
bylaws, or other organizational documents or (ii) any agreement or instrument to
which it is a party or by which it or any of its properties may be subject or
bound which would cause or constitute a Material Adverse Change.

                  (n) Patents, Trademarks, Copyrights, Etc. Each Loan Party owns
or possesses all the material patents, trademarks, service marks, trade names,
copyrights and other intellectual property rights necessary to own and operate
its properties and to carry on its business as presently conducted and planned
to be conducted by such Loan Party without known conflict with the rights of
others and is not a licensee of any such item used in its business except for
Compass software, other software and other similar licenses generally available.

                  (o) Solvency. The Loan Parties, taken as a whole, are Solvent
and after giving effect to the transactions contemplated by the Loan Documents,
including all Indebtedness incurred thereby, and the payment of all fees
relating thereto, will be Solvent, determined as of the Closing Date and as of
each Borrowing Date.

                  (p) Security Interests; Mortgage Liens; Status of the
Collateral.

                        (i) The Liens and security interests granted to the Bank
pursuant to the Patent, Trademark and Copyright Security Agreement, the Pledge
Agreements and the Security Agreement in the Collateral constitute and no Loan
Party will take away any action or fail to take any commercially reasonable
action which would cause them not to continue to constitute Prior Security
Interests under the Uniform Commercial Code as in effect in each applicable
jurisdiction (the "Uniform Commercial Code") or other applicable Law entitled to
all the rights, benefits and priorities provided by the Uniform Commercial Code
or such Law. Upon the filing of financing statements relating to said security
interests in each office and in each jurisdiction where required in order to
perfect the security interests described above, taking possession of any stock
certificates or other certificates evidencing the Pledged Collateral and
recordation of the Patent, Trademark and Copyright Security Agreement in the
United States Patent and Trademark Office and United States Copyright Office as
applicable, all 


                                       33
<PAGE>   37
such action as is necessary or advisable to establish such rights of the Bank
will have been taken, and there will be upon execution and delivery of the
Patent, Trademark and Copyright Security Agreement, the Pledge Agreements and
the Security Agreement, such filings and such taking of possession, no necessity
for any further action in order to preserve, protect and continue such rights,
except the filing of continuation statements with respect to such financing
statements within six months prior to each five-year anniversary of the filing
of such financing statements. All filing fees and other expenses in connection
with each such action have been or will be paid by the Borrowers.

                        (ii) When granted, the Liens granted to the Bank
pursuant to documents delivered pursuant to Section 8.1(m)(vi)(H) shall
constitute a valid first priority Lien under applicable law. All such action as
will be necessary or advisable to establish such Lien of the Bank and its
priority as described in the preceding sentence will be taken at or prior to the
time required for such purpose, and there will be as of the date of execution
and delivery of the documents delivered pursuant to Section 8.1(m)(vi)(H) no
necessity for any further action in order to protect, preserve and continue such
Lien and such priority.

                        (iii) All the shares of capital stock included in the
Pledged Collateral to be pledged pursuant to the Pledge Agreements are or will
be upon issuance validly issued and nonassessable and owned beneficially and of
record by the pledgor free and clear of any Lien or restriction on transfer,
except as otherwise provided by the Pledge Agreements and except as the right of
the Bank to dispose of the Shares may be limited by the Securities Act of 1933,
as amended, and the regulations promulgated by the Securities and Exchange
Commission thereunder and by applicable state securities laws. There are no
shareholder, partnership or other agreements or understandings with respect to
the Shares of capital stock included in the Pledged Collateral.

                  (q) Insurance. Schedule 6.1(q) hereto lists all insurance
policies and other bonds to which each Loan Party is a party on the date hereof,
all of which are valid and in full force and effect. No notice has been given or
claim made and no grounds exist to cancel or avoid any of such policies or bonds
or to reduce the coverage provided thereby. Such policies and bonds provide
adequate coverage from reputable and financially sound insurers in amounts
sufficient to insure the assets and risks of each Loan Party in accordance with
prudent business practice in the industry of each Loan Party.

                  (r) Compliance with Laws. All Loan Parties are in compliance
in all material respects with all applicable Laws (other than Environmental Laws
which are specifically addressed in subsection (x)) in all jurisdictions in
which such Loan Party is presently doing business except where the failure to do
so would not constitute a Material Adverse Change.

                  (s) Material Contracts, Licenses, Permits and Approvals. 

                        (A) As of the date hereof, Schedule 6.1(s) hereto lists
the following contracts relating to the business operations of the Loan Parties:
(i) all employee benefit plans, employment agreements with the executives and
labor contracts to which a 


                                       34
<PAGE>   38
Restricted Subsidiary is a party and other Earn-outs, (ii) the ten (10) largest
employee assistance program contracts and other administrative service
contracts, all existing managed care contracts and all Earn-out agreements;
(iii) all leases of real property to which any Loan Party is a party and under
which the payments made by such Loan Party exceeded or are expected to exceed
$200,000 in the current fiscal year, (iv) any contract or series of contracts
with the same Person for the furnishing or purchase of machinery, equipment or
goods, where the payments made by any Loan Party exceeded or are expected to
exceed $250,000 in the aggregate in the current fiscal year; (v) all provider
agreements where Integra shares capitated risk with a healthcare provider; (vi)
all licenses, permits, approvals, certificates of need, qualifications,
authorizations and accreditations (the lack or loss of which would cause or
constitute a Material Adverse Change ) of each Loan Party; (vii) all other
material contracts filed as exhibits to any report filed by Integra with the
Securities and Exchange Commission during the past twelve months. All such
material contracts are valid, binding and enforceable upon the Loan Party which
is a party to such contract, as the case may be, and, to the best knowledge of
each Loan Party, each of the other parties thereto in accordance with their
respective terms, and there is no material default thereunder, to the knowledge
of the Loan Parties, with respect to parties other than the Loan Parties.

                        (B) Except as set forth on Schedule 6.1(s), each Loan
Party has all material accreditations, authorizations, approvals, certificates
of need, consents, licenses, permits and qualifications (collectively,
"Approvals") required (i) for them to construct, acquire, own, manage, lease
and/or operate their facilities and provide services, or (ii) for them to
receive payment and reimbursement from any patient or third party payor, to the
extent in the case of (i) and (ii) such Approvals are now required. There are no
actions, suits, proceedings or investigations pending or, to the knowledge of
any Loan Party, threatened against any Loan Party at law or in equity before any
Official Body to modify, rescind or revoke any of the Approvals. There are no
actions, suits, proceedings or investigations pending, or to the knowledge of
any Loan Party, threatened against any Loan Party by any Official Body to impose
any sanctions, including any fines, penalties or other sanctions upon any
Borrower except those which would not be expected to cause or constitute a
Material Adverse Change. The Loan Parties have all other material Approvals
required for the lawful operation of their businesses. All material Approvals of
the Loan Parties are in full force and effect and have not been amended or
otherwise modified, rescinded, revoked or assigned except for modifications
which would not be expected to cause or constitute a Material Adverse Change,
and no notice has been received of any violation of applicable Laws or any
refusal to renew any Approval which could reasonably be expected to cause or
constitute a Material Adverse Change. The continuation, validity and
effectiveness of all such Approvals will in no way be adversely affected by the
transactions contemplated by this Agreement. No Loan Party knows of any reason
why any of them will not be able to maintain, after the Closing Date, all
material Approvals necessary or appropriate to construct, own, lease, manage and
operate all of their facilities and to otherwise conduct their businesses as now
conducted and presently proposed to be conducted. There are no deficiencies to
the conditions for participation by any Loan Party in any Medicare, Medicaid or
other reimbursement programs which would preclude or reduce such participation,
nor, other than routine, scheduled audits, is there any pending or, to the
knowledge of the Borrowers, threatened 


                                       35
<PAGE>   39
investigation, proceeding or other action by Medicare or Medicaid to exclude any
Loan Party from participation in such programs except as described in Schedule
6.1(g).

                  (t) Investment Companies. No Loan Party is an "investment
company" registered or required to be registered under the Investment Company
Act of 1940 or under the "control" of an "investment company" as such terms are
defined in the Investment Company Act of 1940 and shall not become such an
"investment company" or under such "control."

                  (u) Margin Stock. Neither Integra nor any of its Subsidiaries
is engaged or intends to engage principally, or as one of its important
activities, in the business of extending credit for the purpose, immediately,
incidentally or ultimately, of purchasing or carrying margin stock (within the
meaning of Regulation U). No part of the proceeds of any Revolving Credit Loan
has been or will be used, immediately, incidentally or ultimately, to purchase
or carry any margin stock or to extend credit to others for the purpose of
purchasing or carrying any margin stock or to refund Indebtedness originally
incurred for such purpose, or for any purpose which entails a violation of or
which is inconsistent with the provisions of the regulations of the Board of
Governors of the Federal Reserve System.

                  (v) Plans and Benefit Arrangements. Except as set forth on 
Schedule 6.1(v) hereto:

                        (i) Integra, its Subsidiaries and each member of the
ERISA Group are in compliance in all material respects with any applicable
provisions of ERISA with respect to all Benefit Arrangements, Plans and
Multiemployer Plans and each Benefit Arrangement and Plan has been administered
in all material respects in accordance with its terms and ERISA. There has been
no Prohibited Transaction with respect to any Benefit Arrangement or any Plan
or, to the best knowledge of Integra and its Subsidiaries, with respect to any
Multiemployer Plan or Multiple Employer Plan, which could result in any material
liability of Integra, its Subsidiaries or any other member of the ERISA Group.
Integra, its Subsidiaries and all members of the ERISA Group have made when due
any and all payments required to be made under any agreement relating to a
Multiemployer Plan or a Multiple Employer Plan or any Law pertaining thereto.
With respect to each Plan and Multiemployer Plan, Integra, its Subsidiaries and
each member of the ERISA Group (i) have fulfilled in all material respects their
obligations under the minimum funding standards of ERISA, (ii) have not incurred
any liability to the PBGC other than for the payment of required premiums and
(iii) have not had asserted against them any penalty for failure to fulfill the
minimum funding requirements of ERISA.

                        (ii) To the best knowledge of each Loan Party, each
Multiemployer Plan and Multiple Employer Plan is able to pay benefits thereunder
when due.

                        (iii) Neither Integra, its Subsidiaries nor any other
member of the ERISA Group has instituted or intends to institute proceedings to
terminate any Plan, which termination resulted or will directly or indirectly
result in any material liability to any Loan Party.


                                       36
<PAGE>   40
                        (iv) No event requiring notice to the PBGC under Section
302(f)(4)(A) of ERISA has occurred or is reasonably expected to occur with
respect to any Plan, and no amendment with respect to which security is required
under Section 307 of ERISA has been made or is reasonably expected to be made to
any Plan.

                        (v) The aggregate actuarial present value of all benefit
liabilities (whether or not vested) under each Plan, determined on a plan
termination basis, as disclosed in, and as of the date of, the most recent
actuarial report for such Plan, does not exceed the aggregate fair market value
of the assets of such Plan by a material amount.

                        (vi) Neither Integra, its Subsidiaries nor any other
member of the ERISA Group has incurred or reasonably expects to incur any
material withdrawal liability under ERISA to any Multiemployer Plan or Multiple
Employer Plan. Neither Integra, its Subsidiaries nor any other member of the
ERISA Group has been notified by any Multiemployer Plan or Multiple Employer
Plan that such Multiemployer Plan or Multiple Employer Plan has been terminated
within the meaning of Title IV of ERISA and, to the best knowledge of Integra
and its Subsidiaries, no Multiemployer Plan or Multiple Employer Plan is
reasonably expected to be reorganized or terminated, within the meaning of Title
IV of ERISA.

                        (vii) To the extent that any Benefit Arrangement is
insured, Integra, its Subsidiaries and all members of the ERISA Group have paid
when due all premiums required to be paid for all periods through and including
the Closing Date. To the extent that any Benefit Arrangement is funded other
than with insurance, Integra, its Subsidiaries and all members of the ERISA
Group have made when due all contributions required to be paid for all periods
through and including the Closing Date.

                  (w) Employment Matters. Each Loan Party is in compliance with
its labor contracts and all applicable federal, state and local labor and
employment Laws including, but not limited to, those related to equal employment
opportunity and affirmative action, labor relations, minimum wage, overtime,
child labor, medical insurance continuation, worker adjustment and relocation
notices, immigration controls and worker and unemployment compensation, except
for any failure to comply which would not be expected to cause or constitute a
Material Adverse Change. There are no outstanding grievances, arbitration awards
or appeals therefrom arising out of any Loan Party's labor contracts or current
or threatened strikes, picketing, handbilling or other work stoppages or
slowdowns at facilities of any Loan Party.

                  (x) Environmental Matters. Except as disclosed on Schedule 
6.1(x) hereto:

                        (i) Neither Integra nor any of its Subsidiaries has
received any Environmental Complaint from any Official Body or private person
alleging that Integra, any of its Subsidiaries or any prior or subsequent owner
of any real property of any Borrower is a potentially responsible party under
the Comprehensive Environmental Response, Cleanup and Liability Act, ("CERCLA")
42 U.S.C. Section 9601, et seq., or is potentially liable under the Solid Waste
Disposal Act, as amended, ("SWDA") 42 U.S.C. Section 6901, et seq., or any
comparable state 


                                       37
<PAGE>   41
or foreign law, statute or regulation of either CERCLA or SWDA and Integra has
no reason to believe that such an Environmental Complaint might be received.
There are no pending or, to any Loan Party's actual knowledge, threatened
Environmental Complaints relating to Integra, any of its Subsidiaries or, to any
Loan Party's knowledge, any prior or subsequent owner of any real property of
any Borrower pertaining to, or arising out of, any Environmental Conditions
which, individually or in the aggregate, if adversely determined could
reasonably be expected to constitute a Material Adverse Change.

                        (ii) To each Loan Party's actual knowledge, except for
conditions, violations or failures which individually and in the aggregate are
not reasonably likely to result in a Material Adverse Change, (A) there are no
circumstances at, on or, to the actual knowledge of each Loan Party, under any
real property of any Borrower that constitute a breach of or non-compliance with
any of the Environmental Laws, and (B) there are, to the actual knowledge of
each Loan Party, no past or present Environmental Conditions at, on or under any
real property of any Borrower or, to each Loan Party's actual knowledge, at, on
or under adjacent property, that prevent compliance with the Environmental Laws
at any real property of any Borrower.

                        (iii) To each Loan Party's actual knowledge, neither the
Real Property nor any structures, improvements, equipment, fixtures, activities
or facilities thereon or thereunder contain or use Regulated Substances except
in compliance in all material respects with Environmental Laws (other than any
noncompliance which individually and in the aggregate is not reasonably likely
to result in a Material Adverse Change). There are no processes, facilities,
operations, equipment or any other activities at, on or, to the actual knowledge
of each Loan Party, under the any real property of any Borrower, or, to each
Loan Party's actual knowledge, at, on or under adjacent property, that currently
result in the release or threatened release of Regulated Substances onto any
real property of any Borrower, except to the extent that such releases or
threatened releases are not a material breach of or otherwise not a material
violation of the Environmental Laws, or are not likely to result in a Material
Adverse Change.

                        (iv) To each Loan Party's actual knowledge, there are no
above ground storage tanks, underground storage tanks, or underground piping
associated with such tanks, used for the management of Regulated Substances at,
on or under any real property of any Borrower that (a) do not have, to the
extent required by applicable Environmental Laws, a full operational secondary
containment system in place, and (b) are not otherwise in compliance in all
material respects with all Environmental Laws (other than any noncompliance
which individually or in the aggregate is not reasonably likely to result in a
Material Adverse Change). To the actual knowledge of each Loan Party, there are
no abandoned underground storage tanks or underground piping associated with
such tanks, previously used for the management of Regulated Substances at, on or
under any real property of any Borrower that have not been either abandoned in
place, or removed, in accordance with the Environmental Laws (other than any
noncompliance which individually or in the aggregate is not reasonably likely to
result in a Material Adverse Change).


                                       38
<PAGE>   42
                        (v) Each Loan Party has all material permits, licenses,
authorizations, plans and approvals necessary under the Environmental Laws for
the conduct of the business of each Loan Party as presently conducted (except
where the failure to hold any such permit, license, authorization or approval is
not reasonably likely to result in a Material Adverse Change). Each Loan Party
has submitted all material notices, reports and other filings required by the
Environmental Laws to be submitted to an Official Body which pertain to past and
current operations on any real property of any Borrower (except where the
failure to make any such submission is not reasonably likely to result in a
Material Adverse Change).

                        (vi) To each Loan Party's actual knowledge, except for
violations which individually and in the aggregate are not likely to result in a
Material Adverse Change, (i) all present and, to the actual knowledge of each
Loan Party, past on-site generation, storage, processing, treatment, recycling,
reclamation or disposal of Regulated Substances at, on, or, to the actual
knowledge of each Loan Party, under any real property of any Borrower and, (ii)
to the actual knowledge of each Loan Party, all off-site transportation,
storage, processing, treatment, recycling, reclamation or disposal of Regulated
Substances by any Loan Party, and to the actual knowledge of each Loan Party, by
any other party, relating to the activities on any real property of any Borrower
has been done in accordance with the Environmental Laws.

                  (y) Senior Debt Status. The obligations of the Loan Parties
under this Agreement, the Revolving Credit Note and the Guaranties, do rank and
will rank at least pari passu in priority of payment with all other indebtedness
of the Loan Parties except indebtedness of the Loan Parties to the extent
secured by Permitted Liens. There is no Lien upon or with respect to any of the
properties or income of any Loan Party which secures indebtedness or other
obligations of any Person except for Permitted Liens.

                  (z) Existing Seller Debt. All Indebtedness owing by any Loan
Party to a seller of a practice is fully described in the seller notes delivered
to the Bank prior to the date hereof and is listed on Schedule 8.2a)(ii).

                  (aa) Year 2000. The Loan Parties have reviewed the areas
within their business and operations which could be adversely affected by, and
have developed a program to address on a timely basis, the risk that certain
computer applications used by the Loan Parties (or any of their material
suppliers, customers or vendors) may be unable to recognize and perform
date-sensitive functions involving dates prior to and after December 31, 1999
(the "Year 2000 Problem"). The Year 2000 Problem will not result in any Material
Adverse Change.

            6.2 Updates to Schedules.

            Should any of the information or disclosures provided on any of the
Schedules attached hereto become outdated or incorrect in any material respect,
the Loan Parties shall promptly provide the Bank in writing with such revisions
or updates to such Schedule as may be necessary or appropriate to update or
correct same; provided, however that no Schedule shall be deemed to have been
amended, modified or superseded by any such correction or update, nor shall any
breach of warranty or representation resulting from the inaccuracy or
incompleteness of any such Schedule be deemed to have been cured thereby, unless
and until the Bank, in its sole 


                                       39
<PAGE>   43
and absolute discretion, shall have accepted in writing such revisions or

obligations hereunder and termination of the Revolving Credit Commitment, each

permitted by Section 8.2(d), each Loan Party shall maintain its corporate
existence and its qualification and good standing in each jurisdiction in which
its ownership or lease of property or the nature of its business makes such
license or qualification necessary, except where the failure to be so licensed
or qualified would not cause or constitute a Material Adverse Change.

Party shall duly pay and discharge all material liabilities to which it is
subject or which are asserted against it, promptly as and when the same shall

income or profits, prior to the date on which penalties attach thereto, except
to the extent that such liabilities, including taxes, assessments or charges,
are being contested in good faith and by appropriate and lawful proceedings
diligently conducted and for which such reserve or other appropriate provisions,
if any, as shall be required by GAAP shall have been made, but only to the
extent that failure to discharge any such liabilities would not result in any
Material Adverse Change or adversely affect the Collateral, provided that such
Loan Party will pay all such liabilities forthwith upon the commencement of
proceedings to foreclose any Lien which may have attached as security therefor.

                  (c) Maintenance of Insurance. Each Loan Party shall insure its
properties and assets against loss or damage by fire and such other insurable
hazards as such assets are commonly insured (including fire, extended coverage,

interruption insurance) and against other risks in such amounts as similar
properties and assets are insured by prudent companies in similar circumstances
carrying on similar businesses, and with reputable and financially sound
insurers, including self-insurance to the extent customary. At the request of
the Bank, each Loan Party shall deliver on the Closing Date and annually
thereafter a certificate signed by such Loan Party's independent insurance
broker certifying as to all insurance then in force with respect to such Loan
Party.

                  (d) Maintenance of Properties and Leases. Each Loan Party
shall maintain in good repair, working order and condition (ordinary wear and
tear excepted) in accordance with the general practice of other businesses of
similar character and size, all of those material properties useful or necessary
to its business, and from time to time, each Loan Party will make or cause to be
made all appropriate repairs, renewals or replacements thereof.

                  (e) Maintenance of Patents, Trademarks, etc. Each Loan Party
shall maintain in full force and effect all patents, trademarks, trade names,
copyrights, licenses, franchises, permits and other authorizations reasonably
necessary for the ownership and operation of its properties and business except
where failure to do so would not cause or constitute a Material Adverse Change.

officers or authorized employees or representatives of the Bank to visit and
inspect any of its properties and to examine and make excerpts from its books
and records or discuss its business affairs, finances and accounts with its
officers, all in such detail and at such times during normal business hours and
as often as any of the Bank may reasonably request, provided that the Bank shall
provide Integra, on behalf of the Borrowers, with reasonable notice prior to any
visit or inspection.

                  (g) Keeping of Records and Books of Account. The Loan Parties
shall maintain and keep proper books of record and account which enable the Loan
Parties to issue financial statements in accordance with GAAP and as otherwise

1999, Consolidated Earnings Available for Fixed Charges and Consolidated Fixed

permit any of its Subsidiaries to, enter into or carry out any transaction
(including, without limitation, purchasing property or services or selling
property or services) with any Affiliate (other than the Loan Parties) unless
such transaction is not otherwise prohibited by this Agreement, is entered into
in the ordinary course of business upon fair and reasonable arm's-length terms

default consists of the failure to pay (beyond any period of grace permitted

right shall have been waived) or the termination of any commitment to lend;

                  (f) Any final judgments or orders for the payment of money in

limitation, the PBGC, or if any taxes or debts owing at any time or times
hereafter to any one of these become payable and the same are not paid within

benefit of creditors, or shall fail generally to pay its debts as they become
due, or shall take any action in furtherance of any of the foregoing.

            9.2 Consequences of Event of Default.

                  (a) If an Event of Default specified under subsections (a)
through (k) of Section 9.1 hereof shall occur and be continuing, the Bank shall
be under no further obligation to make Revolving Credit Loans or issue any
Letters of Credit hereunder and the Bank may (i) by written notice to Integra,
on behalf of the Loan Parties, declare the unpaid principal amount of the
Revolving Credit Note then outstanding and all interest accrued thereon, any
unpaid fees and all other Indebtedness of the Loan Parties to the Bank hereunder
and thereunder to be forthwith due and payable, and the same shall thereupon
become and be immediately due and payable to the Bank without presentment,
demand, protest or any other notice of any kind, all of which are hereby
expressly waived; and (ii) require each Borrower to, and each Borrower shall
thereupon, deposit in a non-interest bearing account with the Bank, as cash
collateral for its obligations under the Loan Documents, an amount equal to the
maximum amount currently or at any time thereafter available to be drawn on all
outstanding Letters of Credit issued on its account, and each Borrower hereby
pledges to the Bank, and grants to the Bank a security interest in, all such
cash as security for such obligations. Upon the curing of all existing Events of
Default to the satisfaction of the Bank, the Bank shall return such cash
collateral to the applicable Borrower; and

                  (b) If an Event of Default specified under subsections (l) or
(m) of Section 9.1 hereof shall occur, the Bank shall be under no further
obligations to make Revolving Credit Loans or issue any Letters of Credit
hereunder and the unpaid principal amount of the Revolving Credit Note then
outstanding and all interest accrued thereon, any unpaid fees and all other
Indebtedness of the Loan Parties to the Bank hereunder and thereunder shall be


                                       56
<PAGE>   60
immediately due and payable, without presentment, demand, protest or notice of
any kind, all of which are hereby expressly waived; and

                  (c) If an Event of Default shall occur and be continuing, any
branch, subsidiary or affiliate of the Bank or participant anywhere in the world
shall have the right, in addition to all other rights and remedies available to
it, without notice to the Loan Parties, to set-off against and apply to the then
unpaid balance of all the Revolving Credit Loans and all other obligations of
such Loan Party hereunder or under any other Loan Document any debt owing to,
and any other funds held in any manner for the account of, such Loan Party by
the Bank or participant or by such branch, subsidiary or affiliate, including,
without limitation, all funds in all deposit accounts (whether time or demand,
general or special, provisionally credited or finally credited, or otherwise)
now or hereafter maintained by such Loan Party for its own account (but not
including funds held in custodian or trust accounts) with the Bank or
participant or such branch, subsidiary or affiliate. The Bank agrees promptly to
notify Integra on behalf of the Loan Parties after any such set-off and
application made by the Bank; provided, however, that the failure to give such
notice shall not affect the validity of such set-off and application. Such right
shall exist whether or not the Bank shall have made any demand under this
Agreement or any other Loan Document, whether or not such debt owing to or funds
held for the account of such Loan Party is or are matured or unmatured and
regardless of the existence or adequacy of any collateral, Guaranty or any other
security, right or remedy available to the Bank; and

                  (d) If an Event of Default shall occur and be continuing, and
provided that the Bank shall have accelerated the maturity of Revolving Credit
Loans of the Borrower or such Loans otherwise shall have been accelerated or
come due pursuant to any of the foregoing provisions of this Section 9.2, the
Bank, may proceed to protect and enforce its rights by suit in equity, action at
law and/or other appropriate proceeding, whether for the specific performance of
any covenant or agreement contained in this Agreement or the Revolving Credit
Note, including as permitted by applicable Law the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of the Bank; and

                  (e) Following the occurrence and during the continuance of an
Event of Default, each Loan Party, at the cost and expense of the Loan Parties
(including the cost and expense of obtaining any of the following referenced
consents, approvals, etc.) will promptly execute and deliver or cause the
execution and delivery of all applications, certificates, instruments,
registration statements, and all other documents and papers the Bank may request
in connection with the obtaining of any consent, approval, registration,
qualification, permit, license, accreditation, or authorization of any Official
Body or other Person necessary or appropriate for the effective exercise of any
rights hereunder or under the other Loan Documents. Without limiting the
generality of the foregoing, each Loan Party agrees that in the event the Bank
shall exercise its rights, hereunder or pursuant to the other Loan Documents, to
sell, transfer, or otherwise dispose of, or vote, consent, operate, or take any
other action in connection with any of the Collateral, each Loan Party shall
execute and deliver (or cause to be executed and delivered) all applications,
certificates, assignments, and other documents that the Bank requests to
facilitate such actions and shall otherwise promptly, fully, and diligently
cooperate with the 


                                       57
<PAGE>   61
Bank and any other necessary persons in making any application for the prior
consent or approval of any Official Body or any other Person to the exercise by
the Bank of any of such rights relating to all or any of the Collateral.
Furthermore, because the Loan Parties agree that the remedies of the Bank at law
for failure of the Loan Parties to comply with the provisions of this Section
9.2(e) would be inadequate and that any such failure would not be adequately
compensable in damages, the Loan Parties agree that the covenants of this
Section 9.2(e) may be specifically enforced; and

                  (f) From and after the date on which the Bank has taken any
action pursuant to this Section 9.2 and until all obligations of the Loan
Parties have been paid in full, any and all proceeds received by the Bank from
any sale or other disposition of the Collateral, or any part thereof, or the
exercise of any other remedy by the Bank, shall be applied as follows:

                        (i) first, to reimburse the Bank for out-of-pocket
costs, expenses and disbursements, including without limitation reasonable
attorneys' fees and legal expenses, incurred by the Bank in connection with
realizing on the Collateral or collection of any obligations of the Loan Parties
under any of the Loan Documents, including advances made by the Bank for the
reasonable maintenance, preservation, protection or enforcement of, or
realization upon, the Collateral, including without limitation, advances for
taxes, insurance, repairs and the like and reasonable expenses incurred to sell
or otherwise realize on, or prepare for sale or other realization on, any of the
Collateral;

                        (ii) second, to the repayment of all Indebtedness then
due and unpaid of the Loan Parties to the Bank incurred under this Agreement or
any of the Loan Documents, provided that such proceeds shall be applied first to
interest, fees, expenses and other Indebtedness other than principal, in such
manner as the Bank may reasonably determine, and then to principal;

                        (iii) the balance, if any, as required by Law; and

                  (g) In addition to all of the rights and remedies contained in
this Agreement or in any of the other Loan Documents, the Bank shall have all of
the rights and remedies of a secured party under the Uniform Commercial Code or
other applicable Law, all of which rights and remedies shall be cumulative and
nonexclusive, to the extent permitted by Law. The Bank may exercise all
post-default rights granted to the Bank under the Loan Documents or applicable
Law.

            9.3 Notice of Sale.

            Any notice required to be given by the Bank of a sale, lease, or
other disposition of the Collateral or any other intended action by the Bank, if
given to Integra ten (10) Business Days prior to such proposed action, shall
constitute commercially reasonable and fair notice thereof to the Loan Parties.

                                  MISCELLANEOUS

            11.1 Modifications, Amendments or Waivers.

            The Bank and the Loan Parties (or Integra on behalf of the Loan
Parties) may from time to time enter into written agreements amending or
changing any provision of this Agreement or any other Loan Document or the
rights of the Bank or the Loan Parties hereunder or thereunder, or may grant
written waivers or consents to a departure from the due performance of the
obligations of the Loan Parties hereunder or thereunder.

            11.2 No Implied Waivers; Cumulative Remedies; Writing Required.

            No course of dealing and no delay or failure of the Bank in
exercising any right, power, remedy or privilege under this Agreement or any
other Loan Document shall affect any other or future exercise thereof or operate
as a waiver thereof; nor shall any single or partial exercise thereof or any
abandonment or discontinuance of steps to enforce such a right, power, remedy or
privilege preclude any further exercise thereof or of any other right, power,
remedy or privilege. The rights and remedies of the Bank under this Agreement
and any other Loan Documents are cumulative and not exclusive of any rights or
remedies which they would otherwise have. Any waiver, permit, consent or
approval of any kind or character on the part of the Bank of any breach or
default under this Agreement or any such waiver of any provision or condition of
this Agreement must be in writing and shall be effective only to the extent
specifically set forth in such writing.

            11.3 Reimbursement and Indemnification of Bank by the Borrowers;
Taxes.

            The Borrowers jointly and severally agree unconditionally upon
demand to pay or reimburse to the Bank and to save the Bank harmless against (i)
liability for the payment of all reasonable out-of-pocket costs, expenses and
disbursements including but not limited to development, negotiation,
preparation, printing, fees and expenses of counsel, accountants, appraisers,
and environmental consultants for the Bank (a) in connection with the
negotiation, preparation, printing, administration, interpretation and
performance of this Agreement, the other Loan Documents and other instruments
and documents to be delivered hereunder, (b) relating to any amendments, waivers
or consents pursuant to the provisions hereof or thereof, (c) in connection with
the enforcement of this Agreement or any other Loan Document, or collection of
amounts due hereunder or thereunder or the proof and allowability of any claim
arising under this Agreement or any other Loan Document, whether in bankruptcy
or receivership proceedings or otherwise, and (d) in any workout, restructuring
or in connection with the protection, preservation, exercise or enforcement of
any of the terms hereof or of any rights hereunder or under any other Loan
Document or in connection with any foreclosure, collection or bankruptcy
proceedings, or (ii) all liabilities, obligations, losses, damages, penalties,
actions, judgments, 


                                       59
<PAGE>   63
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by or asserted against the Bank in any way relating
to or arising out of this Agreement or any other Loan Documents or any action
taken or omitted by the Bank hereunder or thereunder, provided that the
Borrowers shall not be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements (A) if the same results from the Bank's gross negligence or
willful misconduct, or (B) if the Borrowers were not given notice of the subject
claim and the opportunity to participate in the defense thereof, at their
expense, or (C) if the same results from a compromise or settlement agreement
entered into without the consent of the Borrowers. The Borrowers jointly and
severally agree unconditionally to pay all stamp, document, transfer, recording
or filing taxes or fees and similar impositions now or hereafter determined by
the Bank to be payable in connection with this Agreement or any other Loan
Document, and the Borrowers jointly and severally agree unconditionally to save
the Bank harmless from and against any and all present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees or impositions.

            11.4 Holidays.

            Whenever any payment or action to be made or taken hereunder shall
be stated to be due on a day which is not a Business Day, such payment or action
shall be made or taken on the next following Business Day (except as provided in
Section 4.2(a)), and such extension of time shall be included in computing
interest or fees, if any, in connection with such payment or action.

            11.5 Funding by Branch, Subsidiary or Affiliate.

                  (a) Notional Funding. The Bank shall have the right from time
to time, without notice to the Loan Parties, to deem any branch, subsidiary or
affiliate (which for the purposes of this Section 11.5 shall mean any
corporation or association which is directly or indirectly controlled by or is
under direct or indirect common control with any corporation or association
which directly or indirectly controls the Bank) of the Bank to have made,
maintained or funded any Revolving Credit Loan to which the Revolving Credit
Euro-Rate Option applies at any time, provided that immediately following (on
the assumption that a payment were then due from the Borrowers to such other
office) and as a result of such change the Borrowers would not be under any
greater financial obligation pursuant to Section 5.4 than they would have been
in the absence of such change. Notional funding offices may be selected by the
Bank without regard to the Bank's actual methods of making, maintaining or
funding the Loans or any sources of funding actually used by or available to the
Bank.

                  (b) Actual Funding. The Bank shall have the right from time to
time to make or maintain any Loan by arranging for a branch, subsidiary or
affiliate of the Bank to make or maintain such Loan subject to the last sentence
of this Section 11.5(b). If the Bank causes a branch, subsidiary or affiliate to
make or maintain any part of the Loans hereunder, all terms and conditions of
this Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the Revolving Credit Loans to the same extent as if
such 


                                       60
<PAGE>   64
Revolving Credit Loans were made or maintained by the Bank but in no event shall
the Bank's use of such a branch, subsidiary or affiliate to make or maintain any
part of the Revolving Credit Loans hereunder cause the Bank or such branch,
subsidiary or affiliate to incur any cost or expenses payable by any Borrower
hereunder or require any Borrower to pay any other compensation to the Bank
(including, without limitation, any expenses incurred or payable pursuant to
Section 5.4 hereof) which would otherwise not be incurred.

            11.6 Notices.

            All notices, requests, demands, directions and other communications
(collectively "notices") given to or made upon any party hereto under the
provisions of this Agreement shall be by telephone, in person or in writing
(including facsimile communication) unless otherwise expressly permitted
hereunder and shall be delivered or sent by facsimile to the respective parties
at the addresses and numbers set forth under their respective names on the
signature pages hereof, provided, that, all notices to the Loan Parties shall be
sent in care of Integra, unless written direction is given by a Borrower to the
Bank to send notices to a different party and address. All notices shall, except
as otherwise expressly herein provided, be effective (a) in the case of
facsimile, when received, (b) in the case of hand-delivered notice, when hand
delivered, (c) in the case of telephone, when telephoned, provided, however,
that in order to be effective, telephonic notices must be confirmed in writing
no later than the next day by letter or facsimile, and (d) if given by any other
means (including by air courier), when delivered; provided, that notices to the
Bank shall not be effective until received by the Bank.

            11.7 Severability.

            The provisions of this Agreement are intended to be severable. If
any provision of this Agreement shall be held invalid or unenforceable in whole
or in part in any jurisdiction such provision shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without in any
manner affecting the validity or enforceability thereof in any other
jurisdiction or the remaining provisions hereof in any jurisdiction.

            11.8 Governing Law.

            This Agreement shall be deemed to be a contract under the laws of
the Commonwealth of Pennsylvania and for all purposes shall be governed by and
construed and enforced in accordance with the laws of the Commonwealth of
Pennsylvania without regard to its conflict of laws principles.

            11.9 Prior Understanding.

            This Agreement supersedes all prior understandings and agreements,
whether written or oral, between the parties hereto relating to the transactions
provided for herein, including any prior confidentiality agreements and
commitments.

<PAGE>   65
            11.10 Duration; Survival.

            All representations and warranties of the Borrowers contained herein
or made in connection herewith shall survive the making of Revolving Credit
Loans and shall not be waived by the execution and delivery of this Agreement,
any investigation by the Bank, the making of Revolving Credit Loans, or payment
in full of the Revolving Credit Loans. All covenants and agreements of the
Borrowers contained in Sections 8.1, 8.2 and 8.3 shall continue in full force
and effect from and after the date hereof so long as the Borrowers may borrow
hereunder and until termination of the Revolving Credit Commitment. All
covenants and agreements of the Borrowers contained herein relating to the
payment of principal, interest, premiums, additional compensation or expenses
and indemnification, including those set forth in the Revolving Credit Note,
Article V and Section 11.3, and relating to confidentiality shall survive
payment in full of the Revolving Credit Loans, termination or expiration of all
Letters of Credit and termination of the Revolving Credit Commitment.

            11.11 Successors and Assigns.

            This Agreement shall be binding upon and shall inure to the benefit
of the Bank, the Loan Parties and their respective successors and assigns,
except that the Loan Parties may not assign or transfer any of their rights and
obligations hereunder or any interest herein. The Bank may, at its own cost,
make assignments of or sell participations in all or any part of its Revolving
Credit Commitment and the Loans made by it to one or more banks or other
financial institutions, subject to the consent of Integra on behalf of the Loan
Parties with respect to any assignee or participant other than an affiliate of
the Bank, such consent not to be unreasonably withheld. In the case of an
assignment, upon receipt by the Bank of an Assignment and Assumption Agreement,
in form and substance satisfactory to the Bank, the assignee shall have, to the
extent of such assignment (unless otherwise provided therein), the same rights,
benefits and obligations as it would have if it had been a signatory Bank
hereunder, the Revolving Credit Commitment in Section 2.1 shall be adjusted
accordingly, and upon surrender of any Revolving Credit Note subject to such
assignment, the Borrowers shall execute and deliver a new Revolving Credit Note
to the assignee in an amount equal to the amount of the Revolving Credit
Commitment assumed by it and a Revolving Credit Note to the assigning Bank in an
amount equal to the Revolving Credit Commitment retained by it hereunder. In the
case of a participation, the participant shall only have the rights specified in
Section 9.2(c) (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 not to include any voting rights
except with respect to changes of the type referenced in Section 11.1 hereof),
all of the Bank's obligations under this Agreement or any other Loan Document
shall remain unchanged and all amounts payable by the Borrowers hereunder or
thereunder shall be determined as if the Bank had not sold such participation.
The Bank may furnish any publicly available information concerning the Borrowers
and any other information concerning the Borrowers in the possession of the Bank
from time to time to assignees and participants (including prospective assignees
or participants) provided such assignees and participants agree to be bound by
the provisions of Section 11.12.


                                       62
<PAGE>   66
            11.12 Confidentiality.

            The Bank agrees to keep confidential all information obtained from
the Borrowers which is nonpublic and confidential or proprietary in nature
(including any information the Borrowers specifically designate as
confidential), except as provided below, and to use such information only in
connection with its capacity under this Agreement and for the purposes
contemplated hereby. The Bank shall be permitted to disclose such information
(i) to outside legal counsel, accountants and other professional advisors who
need to know such information in connection with the administration and
enforcement of this Agreement, subject to agreement of such persons to maintain
the confidentiality thereof, (ii) to assignees and participants as contemplated
by Section 11.11 (subject to the agreement of such persons to maintain the
confidentiality thereof), (iii) to the extent requested by any bank regulatory
authority or, with notice to the Borrowers, as otherwise required by applicable
Law or by any subpoena or similar legal process, or in connection with any
investigation or proceeding arising out of the transactions contemplated by this
Agreement, (iv) if it becomes publicly available other than as a result of a
breach of this Agreement or becomes available from a source not subject to
confidentiality restrictions, or (v) if Integra shall have consented to such
disclosure.

            11.13 Counterparts.

            This Agreement may be executed by different parties hereto on any
number of separate counterparts, each of which, when so executed and delivered,
shall be an original, and all such counterparts shall together constitute one
and the same instrument.

            11.14 Bank's Consent.

            Whenever the Bank's consent is required to be obtained under this
Agreement or any of the other Loan Documents as a condition to any action,
inaction, condition or event, the Bank shall be authorized to give or withhold
such consent in its sole and absolute discretion (unless otherwise specifically
provided herein) and to condition its consent upon the giving of additional
collateral, the payment of money or any other matter.

            11.15 Exceptions.

            The representations, warranties and covenants contained herein shall
be independent of each other and no exception to any representation, warranty or
covenant shall be deemed to be an exception to any other representation,
warranty or covenant contained herein unless expressly provided, nor shall any
such exceptions be deemed to permit any action or omission that would be in
contravention of applicable Law.

            11.16 CONSENT TO FORUM; WAIVER OF JURY TRIAL.

            EACH BORROWER HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE
JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY, PENNSYLVANIA AND
THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND
WAIVES 


                                       63
<PAGE>   67
PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND CONSENTS THAT ALL SUCH
SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED MAIL DIRECTED TO SUCH
BORROWER AT THE ADDRESSES PROVIDED FOR IN SECTION 11.6 AND SERVICE SO MADE SHALL
BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF. EACH BORROWER WAIVES ANY
OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE. EACH BORROWER AND THE BANK HEREBY WAIVE TRIAL BY JURY IN
ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR
RELATED TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE COLLATERAL TO THE FULL
EXTENT PERMITTED BY LAW.

            11.17 Joinder of Loan Parties.

                  (i) All Subsidiaries of Integra acquired or created on or
after the Closing Date shall join this Agreement as a Guarantor and as a
