      2.1.      THE LOANS.

                From time to time until the Business Day preceding the
Termination Date, each Lender severally agrees, on the terms and conditions set
forth in this Agreement, to make a loan (each


                                        17




a "Loan", and collectively, the "Loans"), to the Borrowers pursuant to this
SECTION 2.1 in amounts such that the aggregate principal amount of the Loans
by such Lender outstanding at any one time does not exceed such Lender's
Commitment.  Each Borrowing under this SECTION 2.1 shall be in an aggregate
amount of $500,000 or multiples thereof; PROVIDED, that the amount of any
Borrowing which would cause the aggregate Loans to equal the maximum aggregate
amount of Loans permitted under this Agreement need not equal an integral
multiple of $500,000.  Amounts borrowed hereunder and repaid or prepaid may be
reborrowed.  Notwithstanding the foregoing and any other provision of this
Agreement, the maximum principal amount of all Loans outstanding at any one time
shall not exceed Twenty Four Million Six Hundred Thousand Dollars ($24,600,000).

      2.2.      NOTICE OF BORROWING.  The Borrowers shall give notice to the
Agent by telephone, at the telephone number listed in the Schedule for Notices,
to Agent's account executive responsible for Borrowers' account, confirmed
immediately in writing, or in writing (by facsimile at the address listed in the
Schedule for Notices), substantially in the form of EXHIBIT B, or to such
other telephone or facsimile number as Agent may designate, (a "Notice of
Borrowing") no later than 12:00 Noon (Pittsburgh, Pennsylvania time) on the
Business Day immediately preceding the requested Loan, specifying:

                (a)   The date of such Borrowing;

                (b)   The aggregate amount of such Borrowing; and

                (c)   That the aggregate amount of such Borrowing, plus the
aggregate outstanding principal amount of the outstanding Loans, do not exceed
the aggregate amount of the Commitments and that all the conditions described in
Article V of this Agreement have been satisfied.

                The Borrowers shall deliver a Notice of Borrowing to the Agent
on the Business Day prior to the Closing Date in an amount equal to or greater
than the amount of Non-Metra Transit Expenditures spent or incurred by Borrowers
from and after July 1, 1995.

      2.3.      NOTICE TO LENDERS; FUNDING OF LOANS.

                (a)   Upon receipt of a Notice of Borrowing, the Agent shall
promptly notify each Lender of the contents thereof and of such Lender's Pro
Rata Share of such Borrowing, and such Notice of Borrowing shall not thereafter
be revocable by the Borrowers.

                (b)   Not later than 1:00 p.m. (Pittsburgh, Pennsylvania time)
on the date of each Borrowing, each Lender shall make available its Pro Rata
Share of such Borrowing, in Federal or other funds immediately available in
Pittsburgh,


                                        18




Pennsylvania, to the Agent at its address referred to in the Schedule for
Notices.  Unless the Agent determines that any applicable condition specified in
ARTICLE V has not been satisfied, the Agent will make the funds so received
from the Lenders available to the Borrowers at 3:00 p.m. (Pittsburgh,
Pennsylvania time) at the Agent's aforesaid address.

                (c)   Unless the Agent shall have received notice from a Lender
prior to the date of any Borrowing that such Lender will not make available to
the Agent such Lender's Pro Rata Share of such Borrowing, the Agent may assume
that such Lender has made such Pro Rata Share available to the Agent on the date
of such Borrowing in accordance with subsection (b) of this SECTION 2.3 and
the Agent may, in reliance upon such assumption, make available to the Borrowers
on such date a corresponding amount.  If and to the extent that such Lender
shall not have so made such Pro Rata Share available to the Agent, such Lender
and the Borrowers severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrowers until the date such amount is
repaid to the Agent, at (i) in the case of the Borrowers, a rate per annum equal
to the Prime Rate, and (ii) in the case of such Lender, the Federal Funds Rate.
If such Lender shall repay to the Agent such corresponding amount, such amount
so repaid shall constitute such Lender's Loan included in such Borrowing for
purposes of this Agreement.

      2.4.      NOTES.

                (a)   The Loans of each Lender to the Borrowers shall be
evidenced by a single Note of the Borrowers payable to the order of such Lender
in an original principal amount equal to such Lender's Commitment.

                (b)   Upon receipt of each Lender's Note pursuant to SECTION
5.1(b), the Agent shall forward such Note to such Lender.  Each Lender shall
record the date, amount and maturity of each Loan made by it to the Borrowers
and the date and amount of each payment of principal made by the Borrowers with
respect thereto, and may, if such Lender so elects in connection with any
transfer or enforcement of its Note, endorse on the schedule forming a part
thereof appropriate notations to evidence the foregoing information with respect
to each such Loan then outstanding; PROVIDED, that the failure of any Lender
to make any such recordation or endorsement shall not affect the obligations of
either Borrower hereunder or under the Notes absent manifest error.  Each Lender
is hereby irrevocably authorized by each Borrower so to endorse its Note and to
attach to and make a part of any Note a continuation of any such schedule as and
when required.


                                        19




      2.5.      MATURITY OF LOANS.  Each Loan included in any Borrowing shall
mature, and the principal amount thereof shall be due and payable, on the
Termination Date.

      2.6.      INTEREST RATES.

                (a)   Except as provided in SECTION 2.6(b), each Loan shall
bear interest on the outstanding principal amount thereof, for each day from the
date such Loan is made until it becomes due, at a rate per annum equal to the
Prime Rate for such day.  Interest shall be payable each calendar month on the
last day of such month and on the Termination Date.

                (b)   Any overdue principal of or interest on any Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the Default Rate.  In addition, from and after the occurrence of any
Special Event of Default (including any Event of Default resulting from the
filing of a bankruptcy case) and continuing until such Event of Default is cured
or has been waived in writing by the Agent in accordance with the terms of this
Agreement, interest shall accrue on the Obligations at the Default Rate and is
payable on demand.  Any interest, reasonable professional fees and expenses of
the Agent, or other reasonable professional fees, expenses and charges of the
Steering Committee Lenders due under SECTION 12.4, which are not paid as and
when due, shall bear interest at the Default Rate.  The interest rate increase
shall take effect immediately upon the occurrence of a Special Event of Default,
without prior notice to Borrowers.

      2.7.      OPTIONAL PREPAYMENTS.

                (a)   Subject to the terms and conditions of the Intercreditor
Agreements, the Borrowers may, upon at least one Business Day's notice to the
Agent, prepay any Borrowing, in each case in whole at any time, or from time to
time in part in amounts aggregating $1,000,000 or any larger multiple of
$1,000,000, by paying the principal amount to be prepaid together with accrued
interest thereon to the date of prepayment.  Each such optional prepayment shall
be paid to the Agent on account of the Obligations for the benefit of the
Lenders and applied to prepay each Lender's Loans in an amount equal to such
Lender's Pro Rata Share of such prepayment.

                (b)   Upon receipt of a notice of prepayment pursuant to this
Section, the Agent shall promptly notify each Lender of the contents thereof and
of such Lender's Pro Rata Share of such prepayment and such notice shall not
thereafter be revocable by the Borrowers.

      2.8.      MANDATORY PREPAYMENT.  If at any time the aggregate principal
amount of the Loans of any Lender outstanding at any time exceeds the amount of
such Lender's Commitment, the Borrowers shall immediately pay to the Agent, for
the benefit of


                                        20




such Lender, the amount necessary to reduce the aggregate principal amount of
such Loans to the amount of such Lender's Commitment.

    2.9.      APPLICATION OF PAYMENTS.  All payments (including
prepayments), other than regularly scheduled interest payments, on the Loans or
on any of the other Obligations (other than Obligations under the Cash
Management System) shall be made to the Agent for application against the
Borrowers' Obligations as follows (regardless of how each Lender may treat such
payments for purposes of its own accounting):  FIRST to then due and
outstanding fees, expenses or other charges of the Agent, or the Steering
Committee Lenders under this Agreement or any of the other Loan Documents to the
extent payable by the Borrowers; SECOND to then due interest on the Loans
accrued and unpaid prior to the date such funds are received by the Lenders; and
THIRD to the principal balance of the Loans.

      2.10.     GENERAL PROVISIONS AS TO PAYMENTS.  The Borrowers shall make
each payment of principal of, and interest on, the Loans and of fees and of all
other Obligations (other than Obligations payable under the Cash Management
System) hereunder, not later than 12:00 Noon (Pittsburgh, Pennsylvania time) on
the date when due, in Federal or other funds immediately available in
Pittsburgh, Pennsylvania, to the Agent at its address referred to in the
Schedule for Notices.  Subject to the provisions of SECTION 2.9, the Agent
will promptly distribute to each Lender entitled to receive a portion of such
payment its Pro Rata Share of each such payment received by the Agent for the
account of the Lenders.  The Borrowers agree to pay to the Agent, upon demand,
the amount of any payment received by the Agent pursuant to the terms of the
Cash Management System that is subsequently returned to any bank that has
transferred funds to the Concentration Account in accordance with the Cash
Management System, because such bank transferred funds in advance of final
collection and such funds are not finally collected.  If such payment has
already been applied in accordance with SECTION 2.9 and is not paid by the
Borrowers within one (1) Business Day after the Agent's demand therefor, then
each Lender shall pay to the Agent the share of such returned payment received
by it.  Upon receipt by Agent of any such payment from the Borrowers, or from
the Lenders in the event the Borrowers fail to make such payment after Agent's
demand, Agent shall pay such funds to Bank of America Illinois, Bank of America
National Trust and Savings Association or Key Bank of Idaho, as appropriate, in
such bank's capacity as a Deposit Bank in order to pay the bank that transferred
funds that were not finally collected and the Loans shall be reinstated to the
extent the Agent makes such payment.  Whenever any payment of principal of, or
interest on, the Loans or of fees with respect to the Loans or of any other
Obligations shall be due on a day which is not a Business Day, the date for
payment thereof shall be extended to the next succeeding Business Day.  If the
date for any payment of principal is extended by


                                        21




operation of law or otherwise, interest thereon shall be payable for such
extended time.

      2.11.     COMPUTATION OF INTEREST AND FEES.  Interest and fees shall be
computed on the basis of a year of 360 days and paid for the actual number of
days elapsed (including the first day but excluding the last day).

      2.12.     CASH MANAGEMENT SYSTEM.  Each Borrower will establish, on or
prior to the Closing Date, and each Borrower will maintain until the Obligations
have been paid in full and all Commitments have been terminated, the Cash
Management System described in SCHEDULE E.

adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Lender (or its Parent) as a consequence of such Lender's
obligations hereunder to a level below that which such Lender (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time, within 15 days
after demand by such Lender (with a copy to the Agent), the Borrowers shall pay
to such Lender such additional amount or amounts as will compensate such Lender
(or its Parent) for such reduction.

                (b)   Each Lender will promptly notify the Borrowers and the
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Lender to compensation pursuant to this SECTION 3.1.

setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive in the absence of manifest error.  In determining such amount,
such Lender may use any reasonable averaging and attribution methods.

Document shall be made without deduction for any Taxes or Other Taxes;

or Other Taxes from any such payments, (i) the sum payable shall be increased as

applicable to additional sums payable under this SECTION 3.2) such Lender or
the Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) such Borrower shall make such
deductions, (iii) such Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable law
and (iv) such Borrower shall furnish to the Agent, at its address referred to in
the Schedule for Notices, the original or a certified copy of a receipt
evidencing payment thereof.

                (b)   The Borrowers agree to indemnify each Lender and the Agent
for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes
imposed or asserted by any jurisdiction on amounts payable under this SECTION
3.2) paid by such Lender or the Agent (as the case may be) and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto.  This indemnification shall be paid within 15 days after such Lender or
the Agent (as the case may be) makes demand therefor.

                (c)   Each Lender organized under the laws of a jurisdiction
outside the United States, on or prior to the date of its execution and delivery
of this Agreement in the case of each Lender listed on the signature pages
hereof and on or prior to the date on which it becomes a Lender in the case of
each other Lender, and from time to time thereafter if requested in writing by
the Borrowers (but only so long as such Lender remains lawfully able to do so),
shall provide the Borrowers with Internal Revenue Service form 1001 or 4224, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Lender is entitled to benefits under an income tax treaty
to which the United States is a party which exempts the Lender from United
States withholding tax or reduces the rate of withholding tax on payments of
interest for the account of such Lender or certifying that the income receivable
pursuant to this Agreement is effectively connected with the conduct of a trade
or business in the United States.

                (d)   For any period with respect to which a Lender has failed
to provide the Borrowers with the appropriate form pursuant to SECTION 3.2(c)
(unless such failure is due to a change in treaty, law or regulation occurring
subsequent to the date on which such form originally was required to be
provided), such Lender shall not be entitled to indemnification under


                                        23




SECTION 3.2(b) or (c) with respect to Taxes imposed by the United States on
payments by such Borrower; PROVIDED, that if a Lender, which is otherwise
exempt from or subject to a reduced rate of withholding tax, becomes subject to
Taxes because of its failure to deliver a form required hereunder, such Borrower
shall take such steps as such Lender shall reasonably request to assist such
Lender to recover such Taxes.

                (e)   If either Borrower is required to pay additional amounts
to or for the account of any Lender pursuant to this SECTION 3.2, then such
Lender will change the jurisdiction of its lending office to an office it
maintains if, in the judgment of such Lender, such change (i) will eliminate or
reduce any such additional payment which may thereafter accrue and (ii) is not
otherwise disadvantageous to such Lender.

                       REPRESENTATIONS AND WARRANTIES

                In order to induce the Agent and the Lenders to enter into this
Agreement, and to make the Loans and other financial accommodations provided for
herein, the Borrowers hereby make the following representations and warranties
to the Agent and to each Lender:

      6.1.      ORGANIZATION AND QUALIFICATION.  Each of the Borrowers is a
corporation duly organized, validly existing and in good standing under the laws
of the state of its incorporation and is duly qualified and in good standing in
each jurisdiction wherein the conduct of its business or the ownership of its
properties requires such qualification, except for those jurisdictions in which
the failure to be qualified and in good standing would not have or result in a
Material Adverse Effect or would not materially adversely affect the ability of
the Collateral Agent to collect any material account receivable.

      6.2.      CORPORATE POWER AND AUTHORIZATION; BINDING EFFECT.  Each of
the Borrowers has the corporate power and has taken all


                                        27




corporate action necessary to authorize it to execute, deliver, and perform this
Agreement and each of the other Restructuring Documents executed by it and to
grant the security interests and liens granted or created thereunder.  This
Agreement constitutes, and when executed the other Restructuring Documents will
constitute, legal and valid obligations of each Borrower binding upon it and
enforceable in accordance with their respective terms, except as the
enforceability of each such Restructuring Document may be subject to or limited
by bankruptcy, insolvency, reorganization, arrangement, moratorium or other
similar laws relating to or affecting the rights of creditors and except as the
availability of equitable remedies are subject to the application of equitable
principles.

      6.3.      NO CONFLICT.  The execution, delivery and performance of this
Agreement, the Notes, the other Restructuring Documents and the secured
financing transactions contemplated hereby, the use of proceeds thereof, and the
performance by the Borrowers (a) do not conflict with or violate any provision
of the Articles of Incorporation or Certificate of Incorporation, as the case
may be, or By-Laws of any Borrower, any material Requirement of Law or any
Contractual Obligation of any Borrower, (b) do not conflict with, constitute a
default or require any consent under any Contractual Obligation of any Borrower,
and (c) do not result in the creation of any Lien other than a Permitted Lien
upon any property or assets of any Borrower.

      6.4.      NO CONSENTS.  All necessary consents, approvals and
authorizations of, filings with, and acts by or with respect to all Governmental
Authorities and other Persons required to be obtained, made or taken by the
Borrowers in connection with the secured financing transactions contemplated
hereby or with the execution, delivery, performance, validity or enforceability
of this Agreement or the other Restructuring Documents, have been obtained, made
or taken, and remain in effect.  All applicable waiting periods have expired
without any Governmental Authority or other Person taking any action which
restricts, prevents or imposes materially adverse conditions upon the
consummation of the secured financing transactions contemplated hereby.

      6.5.      ABSENCE OF LITIGATION.  Except as otherwise set forth in
SCHEDULE 6.5, there are no actions, suits, proceedings or other litigation
(including proceedings by or before any arbitrator or Governmental Authority)
pending, or, to the Borrowers' knowledge, threatened, against or affecting the
Borrowers or any of their Consolidated Subsidiaries or, to the knowledge of the
Borrowers, any basis therefor, (a) which challenge the validity or propriety of
the secured financing transactions contemplated hereby, (b) which could
reasonably be expected to have or result in, individually or in the aggregate, a
Material Adverse Effect, or (c) which could materially affect the ability of the
Borrowers to perform their obligations under this Agreement or the other
Restructuring Documents.


                                        28




      6.6.      NO DEFAULT UNDER THE RESTRUCTURING DOCUMENTS.  No Default or
Event of Default has occurred and is continuing.

      6.7.      CORRECTNESS OF SCHEDULES.  The Certification of Schedules
listed as ITEM NO. 4.24 of the Schedule of Documents and delivered to the
Agent in connection herewith is complete and correct in all material respects.

      6.8.      CORRECTNESS OF FINANCIAL INFORMATION.  The financial
statements described in ITEM NO. 2.00 of the Schedule of Documents and
delivered to the Agent in connection herewith are true and correct and (a)
present fairly, in all material respects, the Consolidated financial condition
of the Borrowers and their Consolidated Subsidiaries as of the date thereof, (b)
disclose all material liabilities of the Borrowers and their Consolidated
Subsidiaries, whether liquidated or unliquidated, fixed or contingent, that are
required to be disclosed under Generally Accepted Accounting Principles as of
the date thereof, and (c) have been prepared in accordance with Generally
Accepted Accounting Principles, consistently applied.  Each of the Budget and
the projections described in ITEM NOS. 1.41 AND 2.4 of the Schedule of
Documents and delivered to Agent in connection herewith are based upon
reasonable estimates and assumptions, and reflect the reasonable estimates of
the Borrowers and their Consolidated Subsidiaries of the results of operations
and other information projected therein.

      6.9.      SECURITY DOCUMENTS.  The Security Documents to which the
Borrowers are a party create in favor of the Collateral Agent for the benefit of
the Lenders to secure the Obligations valid, and, upon the proper filing by the
Collateral Agent of Financing Statements at appropriate offices, a first
priority, perfected security interests in the property and assets described in
the Security Documents capable of being perfected by the filing of a Financing
Statement, subject only to Permitted Liens.

      6.10.     TAXES.  The Borrowers have filed all tax returns which were
required to be filed in any jurisdiction, and paid all taxes shown thereon to be
due or otherwise due upon the Borrowers or any of their properties, income or
franchises, including interest, assessments, fees and penalties (other than any
immaterial amounts, which the Borrowers shall pay or make provision to pay), or
have provided adequate reserves for the payment thereof.  To the best knowledge
of the Borrowers, no claims are threatened, pending or being asserted with
respect to, or in connection with any return referred to in this SECTION 6.10,
which could reasonably be expected to have or result in a Material Adverse
Effect, or could reasonably be expected to affect the Borrowers' ability to
perform their Obligations under this Agreement and the other Restructuring
Documents.


                                        29




      6.11.     NO BURDENSOME RESTRICTIONS.  No Material Contract and no
material Requirement of Law relating to or otherwise affecting the Borrowers
will result in a Material Adverse Effect.

      6.12.     JUDGMENTS.  There are no outstanding or unpaid judgments
against the Borrowers in excess of (a) $100,000 individually, or (b) $2,000,000
in the aggregate, except as expressly set forth in SCHEDULE 6.12.

      6.13.     COMPLIANCE WITH LAWS.  The Borrowers are not and will not be
in violation of, or not in compliance with, any Requirement of Law binding upon
the Borrowers or their properties and assets, including any building, zoning,
occupational safety and health ordinances or regulations relating to their
structure or equipment, or the operation thereof or of its respective business,
or any applicable fair employment, equal opportunity or similar law, ordinance
or regulation, the noncompliance with which could reasonably be expected to have
or result in a Material Adverse Effect, and are not a party to any agreement or
instrument, or subject to any judgment, order, writ, rule, regulation, code or
ordinance which could reasonably be expected to have or result in a Material
Adverse Effect.

      6.14.     COMPLIANCE WITH ERISA.  Each member of the ERISA Group has
fulfilled its obligations under the minimum funding standards of ERISA and the
Internal Revenue Code with respect to each Plan and is in compliance in all
material respects with the presently applicable provisions of ERISA and the
Internal Revenue Code with respect to each Plan.  No member of the ERISA Group
has (i) sought a waiver of the minimum funding standard under Section 412 of the
Internal Revenue Code in respect of any Plan, (ii) failed to make any
contribution or payment to any Plan or Multi-employer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could reasonably result in the imposition of a Lien or the
posting of a bond or other security under ERISA or the Internal Revenue Code or
(iii) except as set forth on SCHEDULE 6.14, incurred any liability under Title
IV of ERISA other than a liability to the PBGC for premiums under Section 4007
of ERISA.

      6.15.     GOVERNMENTAL AUTHORIZATIONS; PERMITS, LICENSES AND
ACCREDITATIONS; OTHER RIGHTS.  The Borrowers have all licenses, permits,
approvals, qualifications, consents, certificates of needs and accreditations
(where such are required) and other authorizations necessary for the lawful
conduct of their respective businesses or operations wherever now conducted and
as planned to be conducted, pursuant to all applicable statutes, laws,
ordinances, rules and regulations of all Governmental Authorities having,
asserting or claiming jurisdiction over the Borrowers, except where such failure
could not have or result in a Material Adverse Effect.  Copies of all such
licenses, permits, approvals, qualifications, consents and other authorizations
shall be provided to the Agent upon request.  The Borrowers are


                                        30




not in default under any of such licenses, permits, approvals, consents,
qualifications or authorizations and no event has occurred, and no condition
exists, which, with the giving of notice, the passage of time, or both, would
constitute a default thereunder or would result in the suspension, revocation,
impairment, forfeiture or non-renewal of any such permit, license, authorization
or accreditation, except where such failure could not have or result in a
Material Adverse Effect.  The continuation, validity and effectiveness of all
material licenses, permits, approvals, consents, qualifications and
authorizations will not be adversely affected by the transactions contemplated
by this Agreement.  The Borrowers know of no reason why they will not be able to
maintain all licenses, permits, approvals, consents, qualifications,
accreditations and other authorizations necessary or appropriate to own and
operate their respective current businesses and to obtain such licenses,
permits, approvals, consents, qualifications and other authorizations necessary
to own and operate their respective current businesses, and otherwise conduct
the business of the Borrowers and their Consolidated Subsidiaries as now
conducted and presently proposed to be conducted.

      6.16.     ENVIRONMENTAL MATTERS.  In the ordinary course of their
business, the Borrowers conduct an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrowers and their
Consolidated Subsidiaries, in the course of which they identify and evaluate
associated liabilities and costs (including any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Materials, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses).  On the
basis of this review, the Borrowers have reasonably concluded that such
associated liabilities and costs, including the costs of compliance with
Environmental Laws, are unlikely to have or result in a Material Adverse Effect.

      6.17.     NO MATERIAL ADVERSE EFFECT.  Since June 26, 1995, there has
been no Material Adverse Effect, other than as disclosed in SCHEDULE 6.17.

      6.18.     CONSOLIDATED SUBSIDIARIES; SUBSIDIARIES.  Each of the
Borrowers' Consolidated Subsidiaries is a corporation or other entity duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, and has all legal powers and all material
governmental licenses,


                                        31




authorizations, consents and approvals required to carry on its business as now
conducted.  Set forth on SCHEDULE 6.18 is a complete and correct list of each
of the Borrower's Subsidiaries.

      6.19.     MARGIN SECURITIES.  Neither Borrower is engaged principally
in, nor has as one of its most important activities, the business of extending
credit for the purpose of purchasing or carrying "margin stock" as that term is
defined in Regulation U promulgated by the Board of Governors of the Federal
Reserve System, as now in effect.  No part of the Indebtedness evidenced by the
Notes, or Indebtedness otherwise created in connection with this Agreement or
the other Restructuring Documents, shall be used, directly or indirectly, for
the purpose of purchasing any such margin stock.  If requested by the Agent, the
Borrowers shall furnish or cause to be furnished to the Agent a statement, in
conformity with the requirements of Federal Reserve Form U-1 referred to in
Regulation U, to the foregoing effect.

      6.20.     INVESTMENT COMPANY ACT.  Neither of the Borrowers is an
"investment company" nor a company "controlled" by an investment company within
the meaning of the Investment Company Act of 1940, as now in effect.

      6.21.     BUSINESS LOCATIONS AND TRADE NAMES.  Set forth on  SCHEDULE
6.21A is a complete and correct list of each location where each of the
Borrowers maintains its chief executive office, its principal place of business,
an office, a place of business or any material financial records.  Set forth on
SCHEDULE 6.21B is a complete and correct list of each name under or by which
each Borrower conducts its business, or by which each Borrower (or its
predecessors in interest) has conducted its business during the past five years.

      6.22.     TITLE TO REAL PROPERTY AND OTHER ASSETS.  The Borrowers have
good and marketable title (or good and marketable leasehold interests with
respect to leased property) to all their Real Property and all personal property
assets and fixtures subject to no Liens other than Permitted Liens.

      6.23.     LABOR MATTERS.  There are no controversies pending between the
Borrowers or their Subsidiaries and their employees which may constitute or
result in a Material Adverse Effect.

      6.24.     NO MISSTATEMENTS.  Neither this Agreement, the Notes, the
other Restructuring Documents, nor any document, instrument and other agreement,
certificate, statement or other information referred to herein or expressly
furnished to the Agent or to any of the Lenders pursuant hereto or thereto,
contains any misstatement of a material fact or omits to state any material fact
or any fact necessary to make the statements contained herein or therein not
misleading on the date furnished or on the Closing Date, except as otherwise
subsequently disclosed to the Agent and all Lenders in writing on or prior to
the Closing Date.


                                        32




      6.25.     RESTRUCTURING.  The Restructuring has occurred.

      6.26.     CASH MANAGEMENT SYSTEM.  Each Borrower acknowledges that the
Cash Management System is part of this Agreement and each of the representations
and warranties made by each Borrower in the Cash Management System constitute
representations and warranties of this Agreement.

occurrence of a Special Event of Default or at any time thereafter, after notice
and the lapse of any cure period, where applicable, and in each and every case,
until such Event of Default shall have been remedied or waived in writing in
accordance with SECTION 12.6, either one or both of the following actions may
be taken: (a) upon the request of the Majority Lenders, the Agent shall, by
notice in writing to the Borrowers, terminate any or all of the Commitments,
whereupon such Commitments of the Lenders thereunder immediately shall
terminate; and (b) upon the request of the Majority Lenders, the Agent shall, by
notice in writing to the Borrowers (a "Notice of Acceleration") declare all the
Obligations due hereunder and under the Loan Documents to be immediately due and
payable, without presentment, demand, protest or notice of any kind (other than
notices provided herein), all of which are hereby expressly waived to the extent
permitted by applicable law; PROVIDED, HOWEVER, that upon the occurrence
of any event specified in either SECTION 9.1(f) or SECTION 9.1(g) (and, in
the case of SECTION 9.1(g), after the lapse of the 20 day period referred to
therein) the Commitments shall automatically terminate, and all amounts owing
under this Agreement, the Notes and the other Loan Documents immediately shall
automatically be due and payable in full without declaration or other notice

Special Event of Default, the Agent immediately, and without expiration of any
period of grace (other than that specifically provided herein), may enforce
payment of all Obligations of any Borrower to the Agent and the Lenders and the
Agent shall be entitled to all remedies available hereunder and thereunder.

                (b)   OCCURRENCE OF A STANDARD EVENT OF DEFAULT.  Upon the

to the Borrowers, terminate any or all of the Commitments, whereupon such
Commitments of the Lenders thereunder immediately shall terminate and may
deliver a Notice of Acceleration declaring all the Obligations due hereunder and
under the Loan Documents to be immediately due and payable, without presentment,
demand, protest or notice of any kind (other than notices provided herein), all
of which are hereby expressly waived to the extent permitted by applicable law.

that specifically provided herein), may enforce payment of all Obligations of
any Borrower to the Agent and the Lenders and the Agent shall be entitled to all
remedies available hereunder and thereunder.


                                        47




      9.3.      OTHER REMEDIES.  Subject to the Intercreditor Agreements, upon
the occurrence of an Event of Default or at any time thereafter, after notice
and the lapse of any cure period, where applicable, and in each and every case,
until such Event of Default shall have been remedied or waived in writing in
accordance with SECTION 12.6, in addition to the remedies listed in SECTION
9.2 upon the earlier of a Notice of Acceleration or acceleration of the
Obligations, the Lenders acting by and through the Agent shall have all rights,

law, including (i) enforcing the Collateral Agent's security interest in the
Collateral by means of one or more public or private sales thereof, (ii) taking
possession of all or any portion of the Collateral, in person or by means of a
court appointed receiver (who shall be appointed without regard to the value of

beneficiary or secured party pursuant to applicable law.  All rights, powers and
remedies of the Agent or the Lenders in connection with each of the Loan
Documents may be exercised at any time or from time to time, are cumulative and
not exclusive, and shall be in addition to any other rights, powers or remedies
provided by law or equity.  Upon the request of the Majority Lenders after the
occurrence of an Event of Default, the Agent shall instruct the Collateral Agent
to exercise any remedies under the Loan Documents, including collection of funds
in deposit accounts and commencement of or actions in court proceedings.

      9.4.      WAIVERS BY BORROWERS.  Except as otherwise provided for in
this Agreement and applicable law, the Borrowers waive (i) presentment, demand
and protest and notice of presentment, dishonor, notice of intent to accelerate,
notice of acceleration, protest, default, nonpayment, maturity, release,
compromise, settlement, extension or renewal of any or all commercial paper,
accounts, contract rights, documents, instruments, chattel paper and guaranties
at any time held by the Agent, the Collateral Agent or the Lenders on which the
Borrowers may in any way be liable and hereby ratify and confirm whatever the
Agent, the Collateral Agent or the Lenders may do in this regard, (ii) all
rights to notice and a hearing prior to the Collateral Agent's taking possession
or control of, or replevy, attachment or levy upon, the Collateral, or any bond
or security which might be required by any court prior to allowing the Agent or
the Collateral Agent to exercise any of its remedies, and (iii) the benefit of
all valuation, appraisal and exemption laws.  Each Borrower acknowledges that it
has been advised by counsel of its choice with respect to the effect of the
foregoing waivers and this Agreement, the other Loan Documents and the
transactions evidenced by this Agreement and the other Loan Documents,
generally.

exist against the Agent.

      10.2.     AGENT AND AFFILIATES.  The Agent shall have the same rights
and powers under this Agreement as any other Lender and may exercise or refrain
from exercising the same as though it were not the Agent, and the Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of business with either Borrower or any Subsidiary or Affiliate of either
Borrower as if it were not the Agent hereunder.

      10.3.     RETENTION OF DOCUMENTS AND INFORMATION TO THE LENDERS.  Agent
shall deliver to each Lender any material documents and written information
required under this Agreement to be delivered by the Borrowers to Agent within a
reasonable period after the Agent's receipt of such documents or information.

      10.4.     DELEGATION OF DUTIES.  The Agent may exercise any of its
powers or execute any of its duties under this Agreement and the other Loan
Documents by or through one or more agents or attorneys-in-fact and shall be
entitled to take, and to rely on, advice of counsel concerning all matters
pertaining to such rights and duties.  The Agent may utilize the services of
such agents and attorneys-in-fact as the Agent in its sole discretion reasonably
determines, and all fees and expenses of such agents and attorneys-in-fact shall
be paid by the Borrowers on demand.  The Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by the
Agent with reasonable care.

      10.5.     LIMITATION OF LIABILITY.  Neither the Agent, nor its officers,
directors, employees, agents, attorneys-in-fact or affiliates shall be (a)
liable for any waiver, consent or approval given or any action taken or omitted

Agreement or the other the Loan Documents or (b) responsible for the
consequences of any oversight or error in judgment by them or


                                        49




such Person whatsoever, except for their or such Person's own gross negligence
or willful misconduct.  The Agent shall not be responsible for (v) the
execution, validity, enforceability, effectiveness or genuineness of this
Agreement or the other Loan Documents, (w) the collectability of any amounts
owing under this Agreement or the other Loan Documents, (x) the value,
sufficiency, enforceability or collectability of any Collateral security
therefore, (y) the failure by any Borrower to perform its Obligations hereunder
or (z) the truth, accuracy and completeness of the recitals, statements,
representations or warranties made by any Borrower or any officer or agent
thereof contained in this Agreement, the other Loan Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent in connection with, this Agreement or the other Loan
Documents.

      10.6.     RELIANCE BY THE AGENT.  The Agent shall not have any
obligation (a) to ascertain or to inquire as to the observance or performance of
any of the conditions, covenants or agreements in this Agreement or the other
Loan Documents or in any document, instrument or agreement at any time
constituting, or intended to constitute, collateral security therefor, (b) to
ascertain or inquire as to whether any notice, consent, waiver or request
delivered to it shall have been duly authorized or is genuine, accurate and
complete, or (c) to inspect the properties, books or records of the Borrowers.
The Agent shall be entitled to rely, and shall be fully protected in relying,
(x) upon any writing, resolution, notice, consent, certificate, affidavit,
letter, cablegram, telegram, telecopy, telex or teletype message, statement,
order or other document, instrument or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons, or (y) upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent.  The Agent may deem and
treat each Lender party hereto or any Assignee as a Lender for all purposes
unless a written notice of the assignment, negotiation or transfer thereof, in
accordance with the provisions of this Agreement, shall have been delivered to
the Agent identifying the name of any successor or Assignee.  The Agent shall be
entitled to fail or refuse, and shall be fully protected in failing or refusing,
to take any action under this Agreement or the other Loan Documents unless (a)
it first shall receive such advice or concurrence of the Majority Lenders as it
deems appropriate, or (b) it first shall be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.  In all cases the
Agent shall be fully protected in acting, or in refraining from acting, under
this Agreement or the Loan Documents in accordance with a request of the
Majority Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of
the Notes.


                                        50




      10.7.     NOTICE OF DEFAULT.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default unless the Agent
has received notice from a Lender or the Borrowers referring to this Agreement,
describing such Event of Default and stating that such notice is a "notice of
default."  If the Agent receives such a notice or has actual knowledge of the
occurrence of an Event of Default, the Agent promptly shall give notice thereof
to the Lenders.  The Agent shall take such action with respect to such Event of
Default as shall be directed by the Majority Lenders; PROVIDED, HOWEVER,
that unless and until the Agent shall have received such directions, the Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Event of Default as it deems advisable in the
best interests of the Lenders.

      10.8.     NON-RELIANCE ON THE AGENT AND THE OTHER LENDERS.  Each Lender
expressly acknowledges that neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates has made any
representations or warranties to it.  The Agent shall have no obligation or
liability to any of the Lenders regarding the creditworthiness or financial
condition of any Borrower.  No act by the Agent hereinafter taken, including any
review of the Borrowers, shall be deemed to constitute any representation or
warranty by the Agent to any Lender.  Each Lender represents to the Agent that,
independently and without reliance upon the Agent or any other Lender and based
on such documents and information as it has deemed appropriate, it has made its
own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Borrowers and has made
its own decision to make its Loans hereunder and to enter into this Agreement.
Each Lender also represents that, independently and without reliance upon the
Agent or any other Lender, and based on such documents and information as it
deems appropriate at the time, it shall continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents and to make such investigation as it
deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrowers.  Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Agent hereunder, the Agent shall have no obligation or liability
to provide any Lender with any credit or other information concerning the
business, operations, property, financial and other condition or
creditworthiness of the Borrowers which may come into the possession of either
the Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

      10.9.     COLLATERAL.  Each of the Lenders represents to the Agent and
each of the other Lenders that it in good faith is not relying upon any "margin
stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.


                                        51




      10.10.    INDEMNIFICATION.  Each of the Lenders shall indemnify, defend
and hold harmless the Agent in its capacity as such (to the extent not
reimbursed by the Borrowers and without limiting the obligation of the Borrowers
to do so), ratably according to their Pro Rata Share, from and against any and
all claims, demands, lawsuits, costs, expenses, fees, liabilities, obligations,
losses, damages, actions, recoveries, judgments, suits, costs, expenses or
disbursements of any kind whatsoever, including interest, penalties and
attorneys' fees and costs, whether direct, indirect, consequential or
incidental, which at any time (including at any time following the payment of
all amounts payable under the Existing Agreements and the Restructuring
Documents) may be imposed on, incurred by or asserted against the Agent in its
capacity as such and not in its individual capacity in any way relating to,
resulting from or arising out of this Agreement, or the Restructuring Documents,
the transactions contemplated hereby or any action taken or omitted by the Agent
under or in connection with any of the foregoing; PROVIDED, HOWEVER, that
no Lender shall be liable for the payment of any portion of such claims,
demands, lawsuits, costs, expenses, fees, liabilities, obligations, losses,
damages, actions, remedies, judgments, suits, costs, expenses or disbursements
to the extent such result from the Agent's gross negligence or willful
misconduct.  The agreements in this SECTION 10.10 shall survive the payment of
all amounts payable under the Restructuring Documents and shall be in addition
to and not in lieu of any other indemnification agreements set forth in the
Restructuring Documents.

      10.11.    AGENT IN ITS INDIVIDUAL CAPACITY.  Agent, in its individual
capacity, and its Affiliates may make loans and other financial accommodations
to, accept deposits from, and generally engage in any kind of business with, the
Borrowers and their Subsidiaries as though Agent was not the Agent hereunder.
With respect to its Existing Indebtedness and any other Loans made or renewed by
it, Agent in its individual capacity shall have the same benefits, rights,
powers and privileges under this Agreement and the Loan Documents as any Lender
and may exercise the same as though it were not Agent, and the terms "Lender"
and "Lenders" shall include Agent in its individual capacity.

      10.12.    SUCCESSOR AGENT.  The Agent may resign as such upon ten days'
prior written notice to the Lenders.  The Agent shall concurrently provide the
Borrowers with a copy of such notice.  If the Agent shall resign as such under
this Agreement, then the Majority Lenders shall appoint from among the Lenders a
successor agent for the Lenders.  A successor agent may also be appointed by the
Majority Lenders if the Agent ceases to have any Loans hereunder, and upon such
appointment of a successor agent the Agent shall resign as such.  Upon
acceptance of its appointment as the successor agent in writing, (a) such
successor agent shall succeed to the rights, powers, privileges and duties of
the Agent, (b) the retiring Agent shall be discharged of all its obligations and
liabilities in such capacity under this Agreement


                                        52




and the Loan Documents, (c) the term "Agent" shall mean such successor agent
effective upon its appointment, and (d) the retiring Agent's rights, powers and
duties as the Agent shall be terminated, without any other or further act or
deed on the part of such former Agent or any of the parties to this Agreement or
their successors and assigns.  With respect to any actions taken or omitted to
be taken by the retiring Agent while it was the Agent (for which retiring Agent
may still have liability), the retiring Agent shall continue to receive the
benefits of this ARTICLE X, including SECTION 10.8.

      10.13.    APPLICABILITY OF SECTION TO THE BORROWERS.  Notwithstanding
any other provision contained in this ARTICLE X, the rights and obligations of
the Borrowers under this Agreement shall not be affected by any provision
otherwise included in this ARTICLE X.  The Borrowers shall be permitted to
rely on communications from the Agent which it reasonably believes are made on
behalf of the Agent and, if specified therein, the Lenders, and except as
otherwise set forth specifically herein, all notices and payments to be made by
the Borrowers hereunder shall be made to the Agent.  Further, if any Lender
shall be in default hereunder, such default shall not affect the rights and
obligations of the Borrowers hereunder.  The Agent shall provide the Borrowers
with prompt notice of any default by any Lender.

      10.14.    AUTHORIZATION TO AGENT TO ENTER INTO AND ABIDE BY FIVE-PARTY
Agreement.  Each Lender authorizes the Agent to enter into the Five-Party
Agreement on behalf of the Lenders and to act in accordance with the terms of
the Five-Party Agreement.  In the event that there is a conflict between the
terms of this Agreement and the terms of the Five-Party Agreement, the Agent is
authorized to comply with the terms of the Five-Party Agreement.


                                  ARTICLE XI

                         JOINT AND SEVERAL LIABILITY

      11.1.     JOINT AND SEVERAL LIABILITY.  Each Borrower agrees that such
Borrower is jointly and severally liable for the Obligations hereunder and that
all Obligations of each Borrower now or hereafter existing under this Agreement,
whether for principal, interest, fees, indemnification, expenses or otherwise,
will be paid strictly in accordance with the terms of this Agreement and the
other Loan Documents regardless of any law, regulation or order now or hereafter
in effect in any jurisdiction affecting any of such terms or the rights of the
Agent or the Lenders with respect thereto.  So long as the Obligations have not
been paid in full, the liability of each Borrower hereunder shall be absolute
and unconditional irrespective of:

                (a)   any taking, exchange, release or nonperfection of any
Collateral or any release or amendment or waiver of or


                                        53




consent to departure from any guaranty, for all or any of the Obligations; or

                (b)   any other circumstance which might otherwise constitute a
defense available to, or a discharge of, any Borrower.

      11.2.     THE GUARANTEES.  If and to the extent any Obligation of any
Borrower to the Agent or any Lender shall be considered an obligation of
guaranty or suretyship, each Borrower hereby unconditionally guarantees the full
and punctual payment (whether at stated maturity, upon acceleration or
otherwise) of the Obligations.  Upon failure by either Borrower to pay
punctually any such amount, the other Borrower shall forthwith on demand pay the
amount not so paid at the place and in the manner specified in this Agreement.

      11.3.     GUARANTEES UNCONDITIONAL.  The Obligations of each Borrower
hereunder shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by:

                (a)   Any extension, renewal, settlement, compromise, waiver or
release in respect of any Obligation of the other Borrower under this Agreement,
any Note, the other Restructuring Documents or by operation of law or otherwise;

                (b)   Any modification or amendment of or supplement to this
Agreement, any Note or the other Restructuring Documents;

                (c)   Any release, impairment, non-perfection or invalidity of
any direct or indirect security for any Obligation of the other Borrower under
this Agreement, any Note or the other Restructuring Documents;

                (d)   Any change in the corporate existence, structure or
ownership of the other Borrower, or any insolvency, bankruptcy, reorganization
or other similar proceeding affecting the other Borrower or its assets or any
resulting release or discharge of any Obligation of the other Borrower contained
in this Agreement, any Note or the other Restructuring Documents;

                (e)   The existence of any claim, set-off or other rights which
a Borrower may have at any time against the other Borrower, the Agent, any
Lender or any other Person, whether in connection herewith or any unrelated
transactions; PROVIDED, that nothing herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

                (f)   Any invalidity or unenforceability relating to or against
the other Borrower for any reason of this Agreement, any Note or the other
Restructuring Documents, or any provision of applicable law or regulation
purporting to prohibit the payment by the other Borrower of the principal of or
interest on


                                        54




any Note or any other amount payable by it under this Agreement or the other
Restructuring Documents; or

                (g)   Any other act or omission to act or delay of any kind by
the other Borrower, the Agent, any Lender or any other Person or any other
circumstance whatsoever which might, but for the provisions of this paragraph,
constitute a legal or equitable discharge of its Obligations under this
Agreement, any Note or the other Restructuring Documents.

      11.4.     DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
Circumstances.  The Borrowers' Obligations hereunder shall remain in full force
and effect until the Commitments shall have terminated and the principal of and
interest on the Notes and all other amounts payable by the Borrowers under this
Agreement shall have been paid in full.  If at any time any payment of the
principal of or interest on any Note or any other amount payable by a Borrower
under this Agreement is rescinded or must be otherwise restored or returned upon
the insolvency, bankruptcy or reorganization of a Borrower or otherwise, the
other Borrower's Obligations hereunder with respect to such payment shall be
reinstated at such time as though such payment had been due but not made at such
time.

      11.5.     WAIVERS BY THE BORROWERS.  The following waivers shall apply
to the guarantees under this ARTICLE XI:

                (a)   EACH BORROWER EXPRESSLY WAIVES THE RIGHT TO REQUIRE THE
AGENT, THE COLLATERAL AGENT OR ANY LENDER FIRST TO PURSUE THE OTHER BORROWER OR
ANY OTHER PERSON, THE COLLATERAL, OR ANY OTHER SECURITY OR GUARANTY THAT MAY BE
HELD FOR THE OBLIGATIONS, OR TO APPLY ANY SUCH SECURITY OR GUARANTY TO THE
OBLIGATIONS BEFORE SEEKING FROM SUCH BORROWER PAYMENT IN FULL OF ITS OBLIGATIONS
TO THE AGENT AND THE LENDERS OR PROCEEDING AGAINST SUCH BORROWER FOR SAME; AND

                (b)   SUCH BORROWER AGREES THAT THE AGENT AND THE LENDERS SHALL
BE UNDER NO OBLIGATION TO:  MARSHAL ANY ASSETS IN FAVOR OF SUCH PERSON; TO
PROCEED FIRST AGAINST ANY OTHER PERSON OR ANY PROPERTY OF ANY OTHER PERSON OR
AGAINST ANY COLLATERAL; ENFORCE FIRST ANY OTHER GUARANTY OBLIGATIONS WITH
RESPECT TO, OR SECURITY FOR, THE OBLIGATIONS; OR PURSUE ANY OTHER REMEDY IN THE
AGENT'S OR ANY LENDER'S POWER THAT SUCH BORROWER MAY NOT BE ABLE TO PURSUE
ITSELF AND THAT MAY LIGHTEN SUCH BORROWER'S BURDEN, ANY RIGHT TO WHICH SUCH
BORROWER HEREBY EXPRESSLY WAIVES.

                      EACH BORROWER ACKNOWLEDGES THAT THE FOREGOING WAIVERS ARE
A MATERIAL INDUCEMENT TO THE AGENT'S AND EACH LENDER'S ENTERING INTO THIS
AGREEMENT AND THAT THE AGENT AND EACH LENDER ARE RELYING UPON THE FOREGOING
WAIVERS IN THEIR FUTURE DEALINGS WITH SUCH BORROWER.  EACH BORROWER WARRANTS AND
REPRESENTS THAT IT HAS  REVIEWED THE FOREGOING WAIVERS WITH ITS LEGAL COUNSEL.



                                        55




      11.6.     SUBROGATION.  Each Borrower agrees that it shall have no right
of subrogation, contribution or reimbursement against the other Borrower until
the Obligations are paid in full.  Each Borrower agrees upon making any payment
hereunder to be subrogated to the rights of the payee against the other Borrower
with respect to such payment or against any direct or indirect security
therefor, or otherwise to be reimbursed, indemnified or exonerated by or for the
account of the other Borrower in respect thereof.

      11.7.     STAY OF ACCELERATION.  In the event that acceleration of the
time for payment of any amount payable by either Borrower under this Agreement
or its Notes is stayed upon insolvency, bankruptcy or reorganization of such
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement shall nonetheless be payable by the other Borrower hereunder
forthwith on demand by the Agent made at the request of the Majority Lenders.


                                  ARTICLE XII

      12.1.     NOTICES.  All notices, requests and other communications to

such other address or facsimile number as such party may hereafter specify for
the purpose by notice to the Agent and the Borrowers.  Each such notice, request

until received.

      12.2.     ENTIRE AGREEMENT.  The execution and delivery of this
Agreement, the Notes and the other Loan Documents supersede all the negotiations
or stipulations concerning matters thereof which preceded or accompanied the
execution and delivery hereof and thereof.  This Agreement, the Notes and the
other Loan Documents are intended, by the parties hereto and thereto, to be a
complete and exclusive statement of the terms and conditions hereof and thereof.

      12.3.     NO WAIVERS.  No failure or delay by the Agent or any Lender in
exercising any right, power or privilege hereunder or under any Note or the
other Restructuring Documents shall operate


                                        56




as a waiver thereof nor shall any single or partial exercise thereof preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege.  The rights and remedies herein provided shall be cumulative and
not exclusive of any rights or remedies provided by law.

      12.4.     EXPENSES; INDEMNIFICATION.

                (a)   The Borrowers shall pay (i) all reasonable out-of-pocket
expenses of the Agent and the Steering Committee Lenders as a group, as such
group is constituted on the Closing Date (as set forth on the attached SCHEDULE
12.4) and as such group may be reconstituted from time to time, including
reasonable fees and disbursements of the Professionals retained by the Steering
Committee Lenders as a whole, in connection with the preparation and
administration of this Agreement, any waiver or consent hereunder or any
amendment hereof or any Default or alleged Default hereunder, (ii) if an Event
of Default occurs, all reasonable out-of-pocket expenses incurred by the Agent
and each Steering Committee Lender, or their Professionals, including the
reasonable fees and disbursements of counsel (including allocated costs of
internal counsel), in connection with such Event of Default and collection,
bankruptcy, insolvency and other enforcement proceedings resulting therefrom,
and (iii) all reasonable out-of-pocket legal fees and expenses of each Lender
accruing from and after the Termination Date in connection with payment of the
Obligations.

                (b)   The Borrowers agree to indemnify the Agent and each
Lender, their respective Affiliates and the respective directors, officers,
agents and employees of the foregoing (each an "Indemnitee") and hold each
Indemnitee harmless from and against any and all liabilities, losses, damages,
costs and expenses of any kind, including the reasonable fees and disbursements
of counsel (including allocated costs of internal counsel), which may be
incurred by such Indemnitee in connection with any investigative, administrative
or judicial proceeding (whether or not such Indemnitee shall be designated a
party thereto) brought or threatened (i) relating to or arising out of this
Agreement or any actual or proposed use of proceeds of Loans hereunder or (ii)
directly or indirectly resulting from, arising out of, or based upon (x) the
presence, use, generation, manufacture, installation, release, discharge,
storage or disposal, at any time, of any Hazardous Materials on, under, in or
about, or the transportation of any such materials to or from, any Real Property
or Real Property owned, leased or operated by Borrower or any Affiliate of
Borrower (collectively, the "Subject Property") or (y) the violation or alleged
violation by Borrower or any Affiliate of Borrower of any law, statute,
ordinance, order, rule, regulation, permit, judgment or license relating to the
use, generation, manufacture, installation, release, discharge, storage or
disposal of Hazardous Materials to or from the Subject Property; PROVIDED,
that no Indemnitee shall have the right to be indemnified hereunder (a) for such
Indemnitee's own


                                        57




gross negligence or willful misconduct or (b) in the case of any Lender, for its
failure to perform the duties expressly required to be performed by it by the
terms of this Agreement, in each case as determined by a court of competent
jurisdiction.

      12.5.     SET-OFF; SHARING OF SET-OFFS.

                (a)   In addition to any rights and remedies of the Lenders
provided by law, the Lenders each shall have a security interest in any and all
deposits of the Borrowers (general or special, time or demand, provisional or
final) at any time held by any Lender which security interest shall secure the
Obligations.  Upon the occurrence and during the continuance of an Event of
Default, provided that it has first received the written consent of the Agent,
without prior notice to the Borrowers (any such notice being specifically waived
by the Borrowers to the fullest extent permitted by applicable law) each Lender
may set off and apply against any Obligations, whether matured or unmatured, of
the Borrowers to the Lenders, any amount owing from the Lenders to the
Borrowers.  No Lender shall exercise any right of set-off it may have against
any Borrower or Guarantor in connection with the Obligations without the prior
written consent of the Agent.  Each Lender promptly shall notify the Borrowers
and the Agent after any such setoff and application made by any such Lender;
PROVIDED, HOWEVER, that failure to give such notice shall not affect the
validity of such setoff and application.  Provided that an Event of Default
described in either SECTION 9.1(f) or SECTION 9.1(g) has not occurred, Bank
of America National Trust and Savings Association expressly agrees that it will
not exercise set-off rights with respect to cash in the Cash Management System
for application against any Indebtedness, liabilities or other obligations of
any of the Borrowers or any of their Consolidated Subsidiaries under any
agreements other than the Loan Documents.  Any such set-off rights will be
subject to the Intercreditor Agreements.

                (b)   Each Lender agrees that if it shall, by exercising any
right of set-off or counterclaim or otherwise, receive payment of a proportion
of the aggregate amount of principal and interest due to it which is greater
than the proportion received by any other Lender in respect of the aggregate
amount of principal and interest due to such other Lender, the Lender receiving
such proportionately greater payment shall purchase such participations in the
Loans held by the other Lenders, and such other adjustments shall be made, as
may be required so that all such payments of principal and interest with respect
to the Loans held by the Lenders shall be shared by the Lenders pro rata;
PROVIDED, that nothing in this Section shall impair the right of any Lender to
exercise any right of set-off or counterclaim it may have and to apply the
amount subject to such exercise to the payment of Indebtedness of a Borrower
other than its Indebtedness hereunder.  Each Borrower agrees, to the fullest
extent it may effectively do so under applicable law, that any holder of a
participation in a Loan, whether or not


                                        58




acquired pursuant to the foregoing arrangements, may exercise rights of set-off
or counterclaim and other rights with respect to such participation as fully as
if such holder of a participation were a direct creditor of such Borrower in the
amount of such participation.

      12.6.     AMENDMENTS AND WAIVERS.  Any provision of this Agreement, the
Notes or the other Loan Documents may be amended or waived only if permitted by
the Five-Party Agreement and if, but only if, such amendment or waiver is in
writing and is signed by the Borrowers, the Agent and the Majority Lenders;
PROVIDED, that (i) the consent of All Lenders shall be required to amend,
modify or waive any provision relating to (a) a change in the amount or the time
of payment of any amount owing on any of the Loans, (b) a change in the rate of
interest or fees to be paid by the Borrowers with respect to any of the Loans,
(c) a change in the definitions of "All Lenders", "Majority Lenders" or "Pro
Rata Share," (d) any increase in the total amounts of the Commitments or in any
Lender's Commitment or any change that subjects any Lender to any additional
obligation, (e) this SECTION 12.6, (f) the release of any Guarantor or any
Borrower, and (g) any change in the terms of the Letter of Credit; (ii) any
change in the duties of or indemnities in this Agreement in favor of any Lender
or in a Lender's Pro Rata Share shall require the consent of such Lender; and
(iii) any change in the duties of or indemnities in favor of the Agent shall
require the consent of the Agent.  Notwithstanding anything to the contrary
herein, the Agent and the Majority Lenders may modify, amend, restate,
supplement or waive any provision of ARTICLE XI, other than SECTION 10.12,
without the consent of the Borrowers; PROVIDED, FURTHER, that amendments or
waivers of this Agreement are subject to the Intercreditor Agreements and to the
Five-Party Agreement.

      12.7.     EFFECT OF WAIVERS; MODIFICATION OF DOCUMENTS.  The Agent's,
the Collateral Agent's, or the Lenders' failure, at any time or times, to
require strict performance by the Borrowers or any other Person of any provision
of this Agreement or any of the other Loan Documents shall not waive, affect or
diminish any right of the Agent, the Collateral Agent or the Lenders thereafter
to demand strict compliance and performance therewith.  Any suspension or waiver
by the Agent or the Lenders of a Default or Event of Default under this
Agreement or any of the other Loan Documents, shall not suspend, waive or affect
any other Default or Event of Default under this Agreement or any of the other
Loan Documents, whether the same is prior or subsequent thereto and whether of
the same or of a different type.  No waiver of any provision of this Agreement
or any other Loan Documents, nor consent to any departure by the Borrowers, or
any other person or entity therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Agent or the Majority Lenders or All
Lenders, as the case may be, necessary to effectuate such waiver or consent and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.


                                        59




      12.8.     SUCCESSORS AND ASSIGNS.

                (a)   The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that neither Borrower may assign or otherwise transfer any of
its rights under this Agreement without the prior written consent of All
Lenders.

                (b)   Any Lender may at any time grant to one or more of the
Existing Lenders (each a "Participant") participating interests in its
Commitment or any or all of its Loans.  In the event of any such grant by a
Lender of a participating interest to a Participant, whether or not upon notice
to the Borrowers and the Agent, such Lender shall remain responsible for the
performance of its obligations hereunder, and the Borrowers and the Agent shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement.  Any agreement pursuant to
which any Lender may grant such a participating interest shall provide that such
Lender shall retain the sole right and responsibility to enforce the Obligations
of the Borrowers hereunder, including the right to approve any amendment,
modification or waiver of any provision of this Agreement.  The Borrowers agree
that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of ARTICLE III with respect to its
participating interest.  An assignment or other transfer which is not permitted
by subsection (c) below shall be given effect for purposes of this Agreement
only to the extent of a participating interest granted in accordance with this
subsection (b).

                (c)   Lenders may at any time assign to one or more of the
Existing Lenders or an Affiliate thereof (each an "Assignee") all of its rights
and obligations under this Agreement and the Notes or any part thereof, and such
Assignee shall assume such rights and obligations, pursuant to an assignment and
assumption agreement executed by such Assignee and such transferor Lender in
substantially the form attached hereto as EXHIBIT E.  Upon execution and
delivery of such instrument and payment by such Assignee to such transferor
Lender of an amount equal to the purchase price agreed to between such
transferor Lender and such Assignee, such Assignee shall be deemed to be a
Lender under this Agreement and shall have all of the rights and obligations of
a Lender with a Commitment as set forth in such instrument of assumption, and
the transferor Lender shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required.  Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Lender, the Agent and the Borrowers shall make appropriate
arrangements so that new Notes are issued to the Assignee and an updated
Schedule of Lenders is annexed to the Credit Agreement.  If the Assignee is not
incorporated under the laws of the United States or a state thereof, then it
shall deliver to the Borrowers and the Agent


                                        60




certification as to its exemption from deduction or withholding of any United
States federal income taxes in accordance with SECTION 3.2.

      12.9.     HEADINGS AND CAPTIONS.  The headings and captions used in this

Agreements and subject to the Five-Party Agreement; PROVIDED, HOWEVER,
that any provision of the Security Documents which imposes additional burdens on
the Borrowers or further restricts the rights of the Borrowers or gives the
Lenders additional rights shall not be deemed to be in conflict or inconsistent
with this Agreement and shall be given full force and effect.

      12.12.    SEVERABILITY.  If any portion of this Agreement, the Notes and
the other Loan Documents shall be judged by a court of competent jurisdiction to
be unenforceable, the remaining portions shall be valid and enforceable to the
extent that the remaining terms thereof provide for the consummation of the
issuance of the Notes, the grant of collateral security therefor, and the
payment of principal and interest on the Loans substantially on the same terms
and subject to the same conditions as set forth herein and therein.

OTHER MANNER PERMITTED BY LAW OR AFFECT THE RIGHT OF THE AGENT OR ANY LENDER TO

COURTS OF ANY OTHER JURISDICTIONS.

      12.15.    WAIVER OF JURY TRIAL.  THE AGENT, EACH LENDER AND THE

counterparts each of which shall be deemed an original, but all of which
together shall constitute one and the same document.
