         2.1     Revolving Credit Commitments.

                 Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, each Bank severally agrees
to make Revolving Credit Loans to the Borrower at any time or from time to time
on or after the date hereof to the Expiration Date provided that after giving
effect to such Loan the aggregate amount of Revolving Credit Loans from such
Bank shall not exceed such Bank's Revolving Credit Commitment minus such Bank's

and amount and subject to the other provisions of this Agreement, the Borrower

Credit Loans and the Letters of Credit Outstanding exceed the Borrowing Base.


                                      -19-

         2.2     Nature of Banks' Obligations with Respect to Revolving
                 Credit Loans.

                 Each Bank shall be obligated to participate in each request
for Revolving Credit Loans pursuant to Section 2.5 [Revolving Credit Loan
Requests] in accordance with its Ratable Share. The aggregate of each Bank's
Revolving Credit Loans outstanding hereunder to the Borrower at any time shall
never exceed its Revolving Credit Commitment minus its Ratable Share of the
Letter of Credit Outstandings. The obligations of each Bank hereunder are
several. The failure of any Bank to perform its obligations hereunder shall not
affect the Obligations of the Borrower to any other party nor shall any other
party be liable for the failure of such Bank to perform its obligations
hereunder. The Banks shall have no obligation to make Revolving Credit Loans
hereunder on or after the Expiration Date.

         2.3      Commitment Fees.

                  Accruing from the date hereof until the Expiration Date, the
Borrower agrees to pay to the Agent for the account of each Bank, as
consideration for such Bank's Revolving Credit Commitment hereunder, a
nonrefundable commitment fee (the "Commitment Fee") equal to .25% per annum
(computed on the basis of a year of 360 days, as the case may be, and actual
days elapsed) on the average daily difference between the amount of (i) such
Bank's Revolving Credit Commitment as the same may be constituted from time to
time and the (ii) the sum of such Bank's Revolving Credit Loans outstanding plus
its Ratable Share of Letters of Credit Outstanding . All Commitment Fees shall
be payable in arrears on the first Business Day of each January, April, July and
October after the date hereof and on the Expiration Date or upon acceleration of
the Notes.

         2.4      Revolving Credit Facility Fee.

                  The Borrower agrees to pay to the Agent for the account of
each Bank, as consideration for such Bank's Revolving Credit Commitment, a
nonrefundable facility fee equal to .25% of such Bank's Revolving Credit
Commitment, payable on the Closing Date.

         2.5      Revolving Credit Loan Requests.

                  Except as otherwise provided herein, the Borrower may from
time to time prior to the Expiration Date request the Banks to make Revolving
Credit Loans by delivering to the Agent, not later than 10:00 a.m., Pittsburgh
time, (i) one (1) Business Day prior to the proposed Borrowing Date with respect
to the making of a Revolving Credit Loan, of a duly completed request therefor
substantially in the form of Exhibit 2.5 or a request by telephone immediately
confirmed in writing by letter, facsimile or telex in such form (each, a "Loan
Request"), it being understood that the Agent may rely on the authority of any
individual making such a telephonic request without the necessity of receipt of
such written confirmation. Each Loan Request shall be irrevocable and shall
specify (i) the proposed Borrowing Date; and (ii) the aggregate amount of the
proposed Loans which shall be in integral multiples of $100,000 and not less
than $500,000. Each Loan Request shall be accompanied by a Borrowing Base
Certificate which certifies, in form and substance reasonably satisfactory to
the Agent, that after giving effect to the


                                      -20-
<PAGE>   28

Loan being requested, the sum of the aggregate outstanding Loans and Letters of
Credit Outstanding shall not exceed the Borrowing Base.

         2.6      Making Revolving Credit Loans.

                  The Agent shall, promptly after receipt by it of a Loan
Request pursuant to Section 2.5 [Revolving Credit Loan Requests], notify the
Banks of its receipt of such Loan Request specifying: (i) the proposed Borrowing
Date and the time and method of disbursement of the Revolving Credit Loans
requested thereby; and (ii) the apportionment among the Banks of such Revolving
Credit Loans as determined by the Agent in accordance with Section 2.2 [Nature
of Banks' Obligations]. Each Bank shall remit its Ratable Share of the principal
amount of each Revolving Credit Loan to the Agent such that the Agent is able
to, and the Agent shall, to the extent the Banks have made funds available to it
for such purpose and subject to Section 7.2 [Each Additional Loan], fund such
Revolving Credit Loans to the Borrower in U.S. Dollars and immediately available
funds at the Principal Office prior to 2:00 p.m., Pittsburgh time, on the
applicable Borrowing Date, provided that if any Bank fails to remit such funds
to the Agent in a timely manner, the Agent may elect in its sole discretion to
fund with its own funds the Revolving Credit Loans of such Bank on such
Borrowing Date, and such Bank shall be subject to the repayment obligation in
Paragraph 16 of Exhibit 10.

         2.7      Revolving Credit Notes.

                  The Obligation of the Borrower to repay the aggregate unpaid
principal amount of the Revolving Credit Loans made to it by each Bank, together
with interest thereon, shall be evidenced by a Revolving Credit Note dated the
Closing Date payable to the order of such Bank in a face amount equal to the
Revolving Credit Commitment of such Bank.

         2.8      Use of Proceeds.

                  The proceeds of the Revolving Credit Loans shall be used to
refinance outstanding indebtedness of the Loan Parties and for working capital
of the Loan Parties and for general corporate purposes of the Loan Parties, all
in accordance with Section 8.1.10 [Use of Proceeds].

         2.9      Letter of Credit Subfacility.

                  At the request of the Borrower, the Agent shall issue on
behalf of the Borrower, on the terms and conditions set forth in Exhibit 2.9,
one or more Letters of Credit; provided, that the aggregate amount of Letters of
Credit Outstanding at any one time shall not exceed $5,000,000.

         2.10     Extension of Expiration Date.

                  2.10.1   Requests; Approval by All Banks.

                           No sooner than ninety (90) but not less than sixty
(60) days prior to the Expiration Date, the Borrower may request a 364-day
extension of the Expiration Date by


                                      -21-
<PAGE>   29

written notice to the Agent and the Banks, and the Banks agree to respond to the
Borrower's request for an extension by the later of forty-five (45) days
following receipt of the request or September 30, 2001; provided, however, that
the failure of any Bank to respond within such time period shall not in any
manner constitute an agreement by such Bank to extend the Expiration Date. If
all Banks elect to extend, the Expiration Date shall be extended for a period of
364 days. If one or more Banks decline to extend or do not respond to Borrower's
request, the provisions of Section 2.10.2 shall apply.

                  2.10.2   Approval by Required Banks.

                           In the event that one or more Banks do not agree to
extend the Expiration Date or do not respond to Borrower's request for an
extension within the time required under Section 2.10.1 (each a "Bank to be
Terminated"), but the Required Banks agree to such extension within such time
then, on or before the existing Expiration Date, the Banks which have agreed to
such extension within the time required under Section 2.10.1 (each an "Extending
Bank") may, with the prior written approval of the Borrower and the Agent,
arrange to have one or more other banks (each an "Assignee Bank") purchase all
of the outstanding Loans, if any, of the Bank to be Terminated and succeed to
and assume the Commitments and all other rights, interests and obligations of
the Bank to be Terminated under this Agreement and the other Loan Documents. Any
such purchase and assumption shall be (1) pursuant to an Assignment and
Assumption Agreement, and (2) subject to and in accordance with Section 11.12.
The Borrower shall pay all amounts due and payable to the Bank to be Terminated
on the effective date of such Assignment and Assumption Agreement (but only to
the extent the rights to such amounts have not been assigned by the Bank to be
Terminated pursuant to such Assignment and Assumption Agreement). In the event
that the Agent shall become a Bank to be Terminated, the provisions of this
Section 2.10 shall be subject to item 14 of Exhibit 10. In the event that the
Loans and Commitments of a Bank to be Terminated are not fully assigned and
assumed pursuant to Section 2.10.2 on or before the existing Expiration Date,
then the Expiration Date shall not be extended for any Bank.

         2.11     Voluntary Reduction of Commitments.

                  The Borrower shall have the right, upon not less than five (5)
Business Days written irrevocable notice to the Agent, to terminate the
Revolving Credit Commitments or, from time to time, to reduce the amount of the
Revolving Credit Commitments, which notice shall specify the date and amount of
any such reduction. Any such reduction shall be in a minimum amount equal to
$1,000,000 or an integral multiple of $500,000 in excess thereof, provided, that
the Revolving Credit Commitments may not be reduced below the sum of the
aggregate principal amount of all Revolving Facility Usage. Each reduction of
Revolving Credit Commitments shall ratably reduce the Revolving Credit
Commitments of the Banks.

         2.12     Option to Increase Commitments.

                  As of the Closing Date, the aggregate amount of the Revolving
Credit Commitments is $20,000,000. Each Bank expressly agrees that so long as no
Event of Default exists, with the consent of the Agent and the Borrower, but
without further consent of any Bank



                                      -22-
<PAGE>   30

(except for a Bank agreeing to increase its Revolving Credit Commitment in
accordance with clause (ii) of this Section 2.12), the aggregate Revolving
Credit Commitments may increase to $25,000,000 (i) by the addition of one or
more lenders as a Bank hereunder (without any increase in the Revolving Credit
Commitment of any Bank party hereto as of such date unless pursuant to the
following clause (ii)) upon execution and delivery to the Agent of a joinder to
this Agreement and any other applicable Loan Document to which a Bank is
required to be a party to, with such joinders to be in form and substance
satisfactory to the Agent and the Borrower, and/or (ii) with the written consent
of a lender that is a Bank hereunder, to an increase in such Bank's Revolving
Credit Commitment.

                           3. [INTENTIONALLY OMITTED]

                                4. INTEREST RATES

         4.1 Interest Rate.

             4.1.1 Revolving Credit Base Rate.

                   The Loans shall bear interest at a fluctuating rate per annum
(computed on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed) equal to the Base Rate, such interest rate to change
automatically from time to time effective as of the effective date of each
change in the Base Rate.

             4.1.2 Rate Quotations.

                   The Borrower may call the Agent on or before the date on
which a 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 Agent or the Banks nor affect the rate of interest which thereafter is
actually in effect when the election is made.

         4.2 Interest After Default.

             To the extent permitted by Law, upon the occurrence of an Event of
Default and until such time such Event of Default shall have been cured or
waived:

             4.2.1 Letter of Credit Fees, Interest Rate.

                   the Letter of Credit Fees and the rate of interest for each
Loan otherwise applicable pursuant to Exhibit 2.9 or Section 4.1 [Interest
Rate], respectively, shall be increased by two percent (2%) per annum; and

             4.2.2 Other Obligations.

                   each other Obligation hereunder if not paid when due shall
bear interest at a rate per annum equal to the sum of the applicable Base Rate
plus an additional two percent


                                      -23-
<PAGE>   31


(2%) per annum from the time such Obligation becomes due and payable and until
it is paid in full.

             4.2.3 Acknowledgment.

                   The Borrower acknowledges that the increase in rates referred
to in this Section 4.2 reflects, among other things, the fact that such Loans or
other amounts have become a substantially greater risk given their default
status and that the Banks are entitled to additional compensation for such risk;
and all such interest shall be payable by Borrower upon demand by Agent.

                                  5. PAYMENTS

         5.1 Payments.

             All payments and prepayments to be made in respect of principal,
interest, Commitment Fees, Facility Fees, Letter of Credit Fees, Agent's Fee or
other fees or amounts due from the Borrower hereunder shall be payable prior to
11:00 a.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
Borrower, and without set-off, counterclaim or other deduction of any nature,
and an action therefor shall immediately accrue. Such payments shall be made to
the Agent at the Principal Office for the ratable accounts of the Banks with
respect to the Loans in U.S. Dollars and in immediately available funds, and the
Agent shall promptly distribute such amounts to the Banks in immediately
available funds, provided that in the event payments are received by 11:00 a.m.,
Pittsburgh time, by the Agent with respect to the Loans and such payments are
not distributed to the Banks on the same day received by the Agent, the Agent
shall pay the Banks the Federal Funds Effective Rate with respect to the amount
of such payments for each day held by the Agent and not distributed to the
Banks. The Agent's and each 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 Loans and other
amounts owing under this Agreement and shall be deemed an "account stated."

         5.2 Pro Rata Treatment of Banks.

             Each borrowing shall be allocated to each Bank according to its
Ratable Share, and each payment or prepayment by the Borrower with respect to
principal, interest, Commitment Fees, Facility Fees, Letter of Credit Fees, or
other fees (except for the Agent's Fee) or amounts due from the Borrower
hereunder to the Banks with respect to the Loans, shall (except as provided in
Section 5.6 [Additional Compensation in Certain Circumstances]) be made in
proportion to the applicable Loans outstanding from each Bank and, if no such
Loans are then outstanding, in proportion to the Ratable Share of each Bank.

         5.3 Interest Payment Dates.

             Interest on Loans shall be due and payable in arrears on the first
Business Day of each month, commencing on January 1, 2001 and on the Expiration
Date or upon acceleration of



                                      -24-
<PAGE>   32

the Notes. Interest on mandatory prepayments of principal under Section 5.5
[Mandatory Prepayments] shall be due on the date such mandatory prepayment is
due. Interest on the principal amount of each Loan or other monetary Obligation
shall be due and payable on demand after such principal amount or other monetary
Obligation becomes due and payable (whether on the stated maturity date, upon
acceleration or otherwise).

         5.4 Voluntary Prepayments.

             5.4.1 Right to Prepay.

                   The Borrower shall have the right at its option from time to
time to prepay the Loans in whole or part without premium or penalty (except as
provided in Section 5.6 [Additional Compensation in Certain Circumstances]) at
any time with respect to any Loan.

                   Whenever the Borrower desires to prepay any part of the
Loans, it shall provide a prepayment notice to the Agent by 1:00 p.m. at least
one (1) Business Day prior to the date of prepayment of Loans setting forth the
following information:

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

                   (z) the total principal amount of such prepayment, which
             shall not be less than $500,000.

                   All prepayment notices shall be irrevocable. The principal
amount of the Loans for which a prepayment notice is given, together with
interest on such principal amount 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. Any prepayment hereunder shall be subject to the Borrower's Obligation to
indemnify the Banks under Section 5.6.2 [Indemnity].

         5.5 Mandatory Prepayments.

             If at any time the Revolving Facility Usage exceeds the Borrowing
Base, the Borrower shall make, immediately upon the Borrower learning of such
excess and whether or not the Agent has given notice to such effect, a mandatory
prepayment of principal equal to the excess of the Revolving Facility Usage over
the Borrowing Base, together with accrued interest on such principal.

         5.6 Additional Compensation in Certain Circumstances.

             5.6.1  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:



                                      -25-
<PAGE>   33
                   (i) subjects any Bank to any tax or changes the basis of
taxation with respect to this Agreement, the Notes, the Loans or payments by the
Borrower of principal, interest, Commitment Fees, or other amounts due from the
Borrower hereunder or under the Notes (except for taxes on the overall net
income of such 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, any 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,
any Bank, or (B) otherwise applicable to the obligations of any 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 any
Bank with respect to this Agreement, the Notes or the making, maintenance or
funding of any part of the Loans (or, in the case of any capital adequacy or
similar requirement, to have the effect of reducing the rate of return on any
Bank's capital, taking into consideration such Bank's customary policies with
respect to capital adequacy) by an amount which such Bank in its sole discretion
deems to be material, such Bank shall from time to time notify the Borrower and
the Agent of the amount determined in good faith (using any averaging and
attribution methods employed in good faith) by such Bank to be necessary to
compensate such Bank for such increase in cost, reduction of income, additional
expense or reduced rate of return. Such notice shall set forth in reasonable
detail the basis for such determination. With respect to amounts due and payable
with respect to which a Bank gives notice at least ten (10) Business Days prior
to the end of a fiscal quarter, such amount shall be due and payable by the
Borrower to such Bank on the last Business Day of the fiscal quarter during
which such notice is given, and with respect to amounts due and payable with
respect to which a Bank gives notice ten (10) Business Days or less prior to the
end of a fiscal quarter, such amount shall be due and payable by the Borrower to
such Bank ten (10) Business Days after such notice is given

             5.6.2 Indemnity.

                   In addition to the compensation required by Section 5.6.1
[Increased Costs, Etc.], the Borrower shall indemnify each Bank against all
liabilities, losses or expenses (including loss of margin and any loss or
expense incurred in liquidating or employing deposits from third parties) which
such Bank sustains or incurs as a consequence of any

                   (i) attempt by the Borrower to revoke (expressly, by later
inconsistent notices or otherwise) in whole or part any Loan Requests under
Section 2.5 [Revolving Credit Loan Requests] or Section 4.2 or notice relating
to prepayments under Section 5.4 [Voluntary Prepayments], or


                                      -26-
<PAGE>   34

               (ii) default by the Borrower in the performance or observance of
any covenant or condition contained in this Agreement or any other Loan
Document, including any failure of the Borrower to pay when due (by acceleration
or otherwise) any principal, interest, Commitment Fee or any other amount due
hereunder.

             If any Bank sustains or incurs any such loss or expense, it shall

costs and expenses and averaging or attribution methods as such Bank shall deem
reasonable) to be necessary to indemnify such 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 Borrower to such Bank
on the last Business Day of the fiscal quarter during which such notice is
given.

of each Loan Party is duly licensed or qualified and in good standing in each
jurisdiction listed on Schedule 6.1.1 and in all other jurisdictions 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 qualified or licensed would not reasonably be expected to result in a
Material Adverse Change.

             6.1.2 Capitalization and Ownership.

                   The authorized capital stock of the Borrower, as of the

             6.1.4 Power and Authority.

                   Each Loan Party has full power to enter into, execute,

of such Loan Document. This Agreement and each other Loan Document constitutes,
or will constitute, legal, valid and binding obligations of each Loan Party
which is or will be a party thereto on and after its date of delivery thereof,
enforceable against such Loan Party in accordance with its terms, except to the
extent that enforceability of any of such Loan Document 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.

             6.1.6 No Conflict.

                   Neither the execution and delivery of this Agreement or the
other Loan Documents by any Loan Party nor the consummation of the transactions

hereof or thereof by any of 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, certificate of limited partnership, partnership

             6.1.7 Litigation.

                   Except as set forth on Schedule 6.1.7, there are no actions,
suits, proceedings or investigations pending or, to the knowledge of the
Borrower, threatened against such Loan Party or any Subsidiary of such Loan
Party at law or equity before any Official Body which, if determined adversely
to any Loan Party would reasonably be expected, individually or in the

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, and subject to the terms and conditions of
the applicable leases. 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.

             6.1.9 Financial Statements.

                   (i) Historical Statements. The Borrower has delivered to the
Agent copies of its audited consolidated year-end financial statements for and
as of the end of the fiscal year ended December 31, 1999 (the "Annual
Statements"). In addition, the Borrower has delivered to the Agent copies of its
unaudited consolidated interim financial statements for the fiscal year to date
and as of the end of the fiscal quarter ended June 30, 2000 (the "Interim
Statements") (the Annual and Interim Statements being collectively referred to
as the "Historical Statements"). The Historical Statements were compiled from
the books and records maintained by the Borrower's management, are correct and
complete in all material respects and fairly represent the consolidated
financial condition of the Borrower 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, subject (in the case of
the Interim Statements) to normal year-end audit adjustments.

 (ii) Financial Projections. The Borrower has delivered to the Agent financial
projections of the Borrower and its Subsidiaries for the period September 30,
2000 through December 31, 2001 derived from various assumptions of the
Borrower's management (the "Financial Projections"). In the good faith judgment
of the Borrower's management as of the Closing Date, the Financial Projections
represent a reasonable range of possible results in light of the history of the
business, present and foreseeable conditions and the intentions of the
Borrower's management. The Financial Projections accurately reflect the
liabilities of the Borrower and its Subsidiaries upon consummation of the
transactions contemplated hereby as of the Closing Date.

             (iii) Accuracy of Financial Statements. Neither the Borrower nor
any Subsidiary of the Borrower has any liabilities, contingent or otherwise, or
forward or long-term commitments that would be required to be disclosed in
accordance with GAAP and are not disclosed in the Historical Statements or in
the notes thereto (except liabilities incurred in the ordinary course of
business since the date of the Historical Statements). Since December 31, 1999,
no Material Adverse Change has occurred.

             6.1.10.2 Margin Stock.

                      None of the Loan Parties or any Subsidiaries of any Loan
Party engages or intends to engage principally, or as one of its important

incidentally or ultimately, of purchasing or carrying margin stock (within the
meaning of Regulation U). No part of the proceeds of any 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. None of the Loan Parties or any Subsidiary of any
Loan Party holds or intends to hold margin stock in such amounts that more than
25% of the reasonable value of the assets of any Loan Party or Subsidiary of any
Loan Party are or will be represented by margin stock.

             6.1.10.3 Section 20 Subsidiaries.

                      The Loan Parties do not intend to use and shall not use
any portion of the proceeds of the Loans, directly or indirectly, to purchase
during the underwriting period, or for thirty (30) days thereafter, Ineligible
Securities being underwritten by a Section 20 Subsidiary.

             6.1.11 Full Disclosure.

                    Neither this Agreement nor any other Loan Document, nor any
certificate, statement, agreement or other documents furnished by any Loan Party
to the Agent or any Bank in connection herewith or therewith, 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.

             6.1.12 Taxes.

                    All federal, state, local and other tax returns required to
have been filed with respect to each Loan Party and each Subsidiary of 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 or Subsidiary of any Loan Party for any period.

             6.1.13 Consents and Approvals.

                    Except for the filing of financing statements in the state
and county filing offices, no consent, approval, exemption, order or
authorization of, or a registration or filing with, any Official Body or any
other Person is 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 6.1.13, all of which
shall have been obtained or made on or prior to the Closing Date except as
otherwise indicated on Schedule 6.1.13.

             6.1.14 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 or other extensions
of credit to be made on the Closing Date under or pursuant to the Loan Documents
which constitutes an Event of Default or Potential Default. None of the Loan
Parties or any Subsidiaries of any Loan Party is in violation of (i) any term of
its certificate of incorporation, bylaws, certificate of limited partnership,
partnership agreement, certificate of formation, limited liability company
agreement or other organizational documents or (ii) any material agreement or
instrument to which it is a party or by which it or any of its properties may be
subject or bound where such violation would constitute a Material Adverse
Change.

rights necessary to own and operate its properties and to carry on its business

or possible, alleged or actual material conflict with, the rights of others.

             6.1.16 Security Interests.

                    The Liens and security interests granted to the Agent for
the benefit of the Banks pursuant to the Note Pledge Agreement, Pledge Agreement
and the Security Agreement (subject to the filing of all requisite financing
statements in the case of the Liens and security interests granted pursuant to
the Security Agreement) in the Collateral constitute and will 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 the Pledged Note, and taking possession of any stock
certificates or other certificates evidencing the Pledged Collateral, as
applicable, all such action as is necessary or advisable to establish such
rights of the Agent will have been taken, and there will be upon execution and
delivery of the Pledge Agreement 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 Borrower.

further obligation to make Loans or issue Letters of Credit, as the case may be,
and the Agent may, and upon the request of the Required Banks, shall (i) by
written notice to the Borrower, declare the unpaid principal amount of the Notes
then outstanding and all interest accrued thereon, any unpaid fees and all other
Indebtedness of the Borrower to the Banks hereunder and thereunder to be
forthwith due and payable, and the same shall thereupon become and be
immediately due and payable to the Agent for the benefit of each Bank without
presentment, demand, protest or any other notice of any kind, all of which are
hereby expressly waived, and (ii) require the Borrower to, and the Borrower
shall thereupon, deposit in a non-interest-bearing account with the Agent, 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

Events of Default to the satisfaction of the Required Banks, the Agent shall
return such cash collateral to the Borrower; and

             9.2.2 Bankruptcy, Insolvency or Reorganization Proceedings.

hereunder and thereunder shall be immediately due and payable, without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived; and

             9.2.3 Set-off.

                   If an Event of Default shall occur and be continuing, any

to be bound by the provisions of Exhibit 10 and any branch, Subsidiary or
Affiliate of such 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 such Loan Party, to set-off against and apply to the then unpaid
balance of all the Loans and all other Obligations of the Borrower and the other
Loan Parties hereunder or under any other Loan Document, any debt owing to, and
any other funds held in any manner for the account of, the Borrower or such
other Loan Party by such Bank or participant or by such branch, Subsidiary or

account (but not including funds held in custodian


                                      -55-
<PAGE>   63

or trust accounts) with such Bank or participant or such branch, Subsidiary or
Affiliate. Such right shall exist whether or not any Bank or the Agent 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 the Borrower or such
other 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 any Bank or the Agent; and

                  9.2.4 Suits, Actions, Proceedings.

                        If an Event of Default shall occur and be continuing,
and whether or not the Agent shall have accelerated the maturity of Loans
pursuant to any of the foregoing provisions of this Section 9.2, the Agent or
any Bank, if owed any amount with respect to the Loans, 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 other Loan Documents, 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 Agent
or such Bank; and

                  9.2.5 Application of Proceeds.

                        From and after the date on which the Agent 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 Agent from
any sale or other disposition of the Collateral, or any part thereof, or the
exercise of any other remedy by the Agent, shall be applied as follows:

                        (i) first, to reimburse the Agent and the Banks for
out-of-pocket costs, expenses and disbursements, including reasonable attorneys'
and paralegals' fees and legal expenses, incurred by the Agent or the Banks in
connection with realizing on the Collateral or collection of any Obligations of
any of the Loan Parties under any of the Loan Documents, including advances made
by the Banks or any one of them or the Agent for the reasonable maintenance,
preservation, protection or enforcement of, or realization upon, the Collateral,
including advances for taxes, insurance, repairs and the like and reasonable
expenses incurred to sell or otherwise realize on, or prepare for sale or other

                        (ii) second, to the repayment of all Indebtedness then
due and unpaid of the Loan Parties to the Banks incurred under this Agreement or
any of the other Loan Documents, whether of principal, interest, fees, expenses
or otherwise, in such manner as the Agent may determine in its discretion; and

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

                  9.2.6 Other Rights and Remedies.

                        In addition to all of the rights and remedies contained
in this Agreement or in any of the other Loan Documents, the Agent shall have
all of the rights and remedies of a


                                      -56-
<PAGE>   64

secured party under the Uniform Commercial Code or other applicable Law, all of
which rights and remedies shall be cumulative and non-exclusive, to the extent
permitted by Law. The Agent may, and upon the request of the Required Banks
shall, exercise all post-default rights granted to the Agent and the Banks under
the Loan Documents or applicable Law.

         9.3 Notice of Sale.

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

                                 10. THE AGENT

             In addition to the other provisions set forth in this Agreement,

Banks 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

Commitment Fee or any other fee payable to any Bank, or reduce the principal

interests, rights or obligations of the Agent in its capacity as Agent or as the
issuer of Letters of Credit shall be effective without the written consent of
the Agent.

         11.2 No Implied Waivers; Cumulative Remedies; Writing Required.

              No course of dealing and no delay or failure of the Agent or any
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 Agent and the Banks
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 any 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 Banks by the Borrower; Taxes.

              The Borrower agrees unconditionally upon demand to pay or
reimburse to each Bank (other than the Agent, as to which the Borrower's
Obligations are set forth in Paragraph 5 of Exhibit 10 [Reimbursement of Agent
By Borrower, Etc.]) and to save such Bank harmless against (i) liability for the
payment of all reasonable out-of-pocket costs, expenses and disbursements
(including fees and expenses of counsel (including allocated costs of staff


                                      -58-
<PAGE>   66

counsel) for each Bank except with respect to (a) and (b) below), incurred by
such Bank (a) in connection with the administration and interpretation of this
Agreement, and other instruments and documents to be delivered hereunder, (b)
relating to any amendments, waivers or consents pursuant to the provisions
hereof, (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 or 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, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by or asserted against such Bank, in its capacity as such, in any
way relating to or arising out of this Agreement or any other Loan Documents or
any action taken or omitted by such Bank hereunder or thereunder, provided that
the Borrower 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 such Bank's gross
negligence or willful misconduct, or (B) if the Borrower was not given notice of
the subject claim and the opportunity to participate in the defense thereof, at
its expense (except that the Borrower shall remain liable to the extent such
failure to give notice does not result in a loss to the Borrower), or (C) if the
same results from a compromise or settlement agreement entered into without the
consent of the Borrower, which shall not be unreasonably withheld. The Banks
will attempt to minimize the fees and expenses of legal counsel for the Banks
which are subject to reimbursement by the Borrower hereunder by considering the
usage of one law firm to represent the Banks and the Agent if appropriate under
the circumstances. The Borrower agrees unconditionally to pay all stamp,
document, transfer, recording or filing taxes or fees and similar impositions
now or hereafter determined by the Agent or any Bank to be payable in connection
with this Agreement or any other Loan Document, and the Borrower agrees
unconditionally to save the Agent and the Banks 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 payment of a Loan to be made or taken hereunder shall be
due on a day which is not a Business Day such payment shall be due on the next
Business Day and such extension of time shall be included in computing interest
and fees, except that the Loans shall be due on the Business Day preceding the
Expiration Date if the Expiration Date is not a Business Day. Whenever any
payment or action to be made or taken hereunder (other than payment of the
Loans) 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, and
such extension of time shall not be included in computing interest or fees, if
any, in connection with such payment or action.

11.5.1. If any 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 Loans to the same extent as if such Loans were made or
maintained by such Bank, but in no event shall any Bank's use of such a branch,
Subsidiary or Affiliate to make or maintain any part of the Loans hereunder
cause such Bank or such branch, Subsidiary or Affiliate to incur any cost or
expenses payable by the Borrower hereunder or require the Borrower to pay any
other compensation to any Bank (including any expenses incurred or payable
pursuant to Section 5.6 [Additional Compensation in Certain Circumstances])

relieved of its obligations as a result of any arrangement permitted by this

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,

         11.11 Intentionally Omitted.

         11.12 Successors and Assigns.

                  (i) This Agreement shall be binding upon and shall inure to

respective successors and assigns, except that the Borrower may not may assign
or transfer any of its rights and Obligations hereunder or any interest herein.

assignee, such consent not to be unreasonably withheld, provided that (1) no
consent of the Borrower shall be required (A) if an Event of Default exists and
is continuing, or (B) in the case of an assignment by a Bank to an Affiliate of
such Bank, and (2) any assignment by a Bank to a Person other than an Affiliate
of such Bank may not be made in amounts less than the lesser of $2,500,000 or
the amount of the assigning Bank's Commitment. In the case of an assignment,
upon receipt by the Agent of the Assignment and Assumption Agreement, 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 Commitments shall be adjusted accordingly,
and upon surrender of any Note subject to such assignment, the Borrower shall
execute and deliver a new Note to the assignee in an amount equal to the amount
of the Revolving Credit Commitment assumed by it and a new Revolving Credit Note
to the assigning Bank in an amount equal to the Revolving Credit Commitment
retained by it hereunder. Any Bank which assigns any or all of its Commitment or
Loans to a Person other than an Affiliate of such Bank shall pay to the Agent a
service fee in the amount of $3,500 for each assignment. In the case of a
participation, the participant shall only have the rights specified in Section

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 Sections 11.1.1
[Increase of Commitment, Etc.], 11.1.2 [Extension of Payment, Etc.], or 11.1.3
[Release of Collateral or Guarantor]), all of such Bank's obligations under this
Agreement or any other Loan Document shall remain unchanged, and all amounts
payable by any Loan Party hereunder or thereunder shall be determined as if such
Bank had not sold such participation.

                  (ii) Any assignee or participant which is not incorporated
under the Laws of the United States of America or a state thereof shall deliver
to the Borrower and the Agent the form of certificate described in Section 11.18
[Tax Withholding Clause] relating to federal income tax withholding. Each Bank
may furnish any publicly available information concerning any Loan Party or its
Subsidiaries and any other information concerning any Loan Party or its
Subsidiaries in the possession of such Bank from time to time to assignees and
participants (including prospective assignees or participants), provided that
such assignees and participants agree to be bound by the provisions of Section
11.13 [Confidentiality].

                  (iii) Notwithstanding any other provision in this Agreement,
any Bank may at any time pledge or grant a security interest in all or any
portion of its rights under this Agreement, its Note and the other Loan
Documents to any Federal Reserve Bank in accordance with Regulation A of the FRB
or U.S. Treasury Regulation 31 CFR Section 203.14 without notice to or consent
of the Borrower or the Agent. No such pledge or grant of a security interest
shall release the Transferor Bank of its obligations hereunder or under any
other Loan Document.

               11.13.1 General.

                       The Agent and the Banks each agree to keep confidential
all information obtained from any Loan Party or its Subsidiaries which is
nonpublic and confidential or proprietary in nature (including any information
the Borrower specifically designates as confidential), except as provided below,
and to use such information only in connection with their respective capacities
under this Agreement and for the purposes contemplated hereby. The Agent and the
Banks 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,
(ii) to assignees and participants as contemplated by Section 11.12, (iii) to
the extent requested by any bank regulatory authority or, with notice to the
Borrower, 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 known to be subject to confidentiality restrictions,
or (v) if the Borrower shall have consented to such disclosure.

               11.13.2 Sharing Information With Affiliates of the Banks.

                       The Borrower, on its own behalf and on behalf of each
other Loan Party, acknowledges that from time to time financial advisory,
investment banking and other services may be offered or provided to the Borrower
or one or more of its Affiliates (in connection with this Agreement or
otherwise) by any Bank or by one or more Subsidiaries or Affiliates of such Bank
and the Borrower, on its own behalf and on behalf of each other Loan Party,
hereby authorizes each Bank to share any information delivered to such Bank by
such Loan Party and its Subsidiaries pursuant to this Agreement, or in
connection with the decision of such Bank to enter into this Agreement, to any
such Subsidiary or Affiliate of such Bank, it being understood that any such
Subsidiary or Affiliate of any Bank receiving such information shall be bound by
the provisions of Section 11.13.1 as if it were a Bank hereunder. Such
authorization shall survive the repayment of the Loans and other Obligations and
the termination of the Commitments.

         11.14 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.

         11.15 Agent's or Bank's Consent.

               Whenever the Agent's or any 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 Agent and each Bank shall be
authorized to give or withhold such consent in its sole


                                      -63-
<PAGE>   71

and absolute discretion and to condition its consent upon the giving of
additional collateral, the payment of money or any other matter.

         11.16 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

nor shall any such exceptions be deemed to permit any action or omission that
would be in contravention of applicable Law.

         11.17 CONSENT TO FORUM; WAIVER OF JURY TRIAL.

               THE BORROWER HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE
JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY AND THE UNITED

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 THE
BORROWER AT THE ADDRESSES PROVIDED FOR IN SECTION 11.6 AND SERVICE SO MADE SHALL
BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF. THE 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. THE BORROWER, THE AGENT AND THE BANKS 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.

         11.18 Tax Withholding Clause.

               Each Bank or assignee or participant of a Bank that is not
incorporated under the Laws of the United States of America or a state thereof
agrees that it will deliver to each of the Borrower and the Agent two (2) duly
completed copies of the following: (i) Internal Revenue Service Form W-9, 4224
or 1001, or other applicable form prescribed by the Internal Revenue Service,
certifying that such Bank, assignee or participant is entitled to receive
payments under this Agreement and the other Loan Documents without deduction or
withholding of any United States federal income taxes, or is subject to such tax
at a reduced rate under an applicable tax treaty, or (ii) Internal Revenue
Service Form W-8 or other applicable form or a certificate of such Bank,
assignee or participant indicating that no such exemption or reduced rate is
allowable with respect to such payments. Each Bank, assignee or participant
required to deliver to the Borrower and the Agent a form or certificate pursuant
to the preceding sentence shall deliver such form or certificate as follows: (A)
each Bank which is a party hereto on the Closing Date shall deliver such form or
certificate at least five (5) Business Days prior to the first date on which any
interest or fees are payable by the Borrower hereunder for the account of such
Bank; (B) each assignee or


                                      -64-
<PAGE>   72

participant shall deliver such form or certificate at least five (5) Business
Days before the effective date of such assignment or participation (unless the
Agent in its sole discretion shall permit such assignee or participant to
deliver such form or certificate less than five (5) Business Days before such
date in which case it shall be due on the date specified by the Agent). Each
Bank, assignee or participant which so delivers a Form W-8, W-9, 4224 or 1001
further undertakes to deliver to each of the Borrower and the Agent two (2)
additional copies of such form (or a successor form) on or before the date that
such form expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent form so delivered by it, and such
amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Borrower or the Agent, either certifying that such Bank,
assignee or participant is entitled to receive payments under this Agreement and
the other Loan Documents without deduction or withholding of any United States
federal income taxes or is subject to such tax at a reduced rate under an
applicable tax treaty or stating that no such exemption or reduced rate is
allowable. The Agent shall be entitled to withhold United States federal income
taxes at the full withholding rate unless the Bank, assignee or participant
establishes an exemption or that it is subject to a reduced rate as established
pursuant to the above provisions.

         11.19 Joinder of Guarantors; Pledge of Stock and Security Interest in
Assets of Subsidiaries.

                  (1) each Significant Subsidiary of the Borrower to
