Notes") in substantially the form attached hereto as Exhibit A, with the blanks

Credit Loans shall be due and payable on the Revolving Credit Maturity Date.

         2.02. Fees; Reduction of the Committed Amounts.

         (a) Commitment Fee. The Borrower shall pay to the Agent for the account

Maturity Date, of the amount (not less than zero) equal to (i) such Lender's
Revolving Credit Committed Amount on such day, minus (ii) such Lender's

Agent for the account of each Lender a closing fee equal to 0.05% of such
Lender's Revolving Credit Committed Amount.

other fees at the times and in the amounts previously agreed upon among the
Agent and the Borrower.

         (d) Optional Reduction of the Revolving Credit Committed Amounts. The
Borrower may at any time or from time to time reduce Pro Rata the Revolving
Credit Committed Amounts of the Lenders to an aggregate amount (which may be
zero) not less than the sum of the outstanding Revolving Credit Loans plus the
principal amount of Revolving Credit Loans not yet outstanding as to which
notice has been given by Borrower under Section 2.05 hereof. Any reduction of
the Revolving Credit Committed Amounts shall be in an aggregate amount not less
than $5,000,000 which is an integral multiple of $1,000,000. Reduction of the
Revolving Credit Committed Amounts shall be made by providing not less than 10
days notice (which notice shall be irrevocable) to such effect to the Agent.

         2.03. Extension of Revolving Credit Maturity Date. On and after the
first Anniversary Date hereof, the Revolving Credit Maturity Date may be
extended for successive one year periods at the request of the Borrower with the
express consent of each Lender as provided below. Not later than the date 60
days prior to each Anniversary Date, the Borrower shall, at its option, in a
written notice to the Agent request (an "Extension Request") that the Revolving
Credit Maturity Date be extended for a period of one year. The Agent shall
promptly inform the Lenders of such Extension Request. Each Lender that agrees
with such Extension Request shall deliver to the Agent its express written
consent thereto no later than such Anniversary Date. If (i) any Lender notifies
the Agent in writing prior to such Anniversary Date that it will not consent to
such Extension Request or (ii) all of the Lenders have not in writing expressly
consented to any such Extension Request as provided in the preceding sentence,
then the Agent shall so notify the Borrower and the Borrower, at its option, may
replace each Lender which has not agreed to such Extension Request (a
"Nonextending Lender") with another commercial lending institution (a
"Replacement Lender") by giving (not later than 90 days after such Anniversary
Date) notice of the name of such Replacement Lender to the Agent. Upon notice
from


                                      -16-


the Agent, each Nonextending Lender shall promptly (but in no event later than
the date which is 120 days after such Anniversary Date) assign all of its
interests hereunder to such Replacement Lender in accordance with the provisions
of Section 9.14(c) hereof. If, prior to the date which is 120 days after such
Anniversary Date some, but not all, of the Lenders have agreed to such Extension
Request, and each Nonextending Lender has not been replaced by the Borrower in
accordance with the terms of this Section 2.03, the Revolving Credit Maturity
Date shall be extended in accordance with such Extension Request; provided,
however, that on the original Revolving Credit Maturity Date (as such date may
have been previously extended), the Borrower shall pay to the Agent for the
account of such Nonextending Lender such Nonextending Lender's Pro Rata share of
all outstanding Revolving Credit Loans, together with interest thereon, and all
fees due and payable to such Nonextending Lender and the total Revolving Credit
Commitment shall be irrevocably reduced by an amount equal to the Commitment of
each Nonextending Lender. If all Lenders consent to any such Extension Request
(or, if any Nonextending Lenders are replaced in accordance with this Section),
then as of 5:00 p.m. Pittsburgh time on the date which is 120 days after such
Anniversary Date the Revolving Credit Maturity Date shall be deemed to have been
extended for, and shall be the date, one year after the then effective Revolving
Credit Maturity Date.

         2.04. Maximum Aggregate Amount of Revolving Credit Loans. No Loan shall
be made or requested or permitted to remain outstanding hereunder if the making 
or maintenance of such Loan would cause the aggregate amount of all Revolving
Credit Loans outstanding hereunder to exceed the sum of the aggregate Revolving
Credit Committed Amounts of all Lenders.

         2.05. Making of Loans. Whenever the Borrower desires that the Lenders
make Revolving Credit Loans, the Borrower shall provide Standard Notice to the
Agent setting forth the following information (a separate notice being required
for each such type of Loans):

                  (a) The date, which shall be a Business Day, on which such
         proposed Loans are to be made;

                  (b) The aggregate principal amount of such proposed Loans,
         which shall be the sum of the principal amounts selected pursuant to
         clause (c) of this Section 2.05, and which shall be an integral
         multiple of $1,000,000 not less than $5,000,000;

                  (c) The interest rate Option or Options selected in accordance
         with Section 2.06(a) hereof and the principal amounts selected in
         accordance with Section 2.06(d) hereof of the Base Rate Portion and
         each Funding Segment of the CD Rate Portion and the Euro-Rate Portion,
         as the case may be, of such proposed Loans; and


                                      -17-



                  (d) With respect to each such Funding Segment of such proposed
         Loans, the Funding Period to apply to such Funding Segment, selected in
         accordance with Section 2.06(c) hereof.

Standard Notice having been so provided, the Agent shall promptly notify each
Lender of the information contained therein and of the amount of such Lender's
Loan. Unless any applicable condition specified in Article IV hereof has not
been satisfied, on the date specified in such Standard Notice each Lender shall
make the proceeds of its Loan available to the Agent at the Agent's Office, no
later than 12:00 o'clock Noon, Pittsburgh time, in funds immediately available
at such Office.

                  2.06. Interest Rates.

                  (a) Optional Bases of Borrowing. The unpaid principal amount
of the Revolving Credit Loans shall bear interest for each day from and
including the date on which funds are made available to the Borrower by the
Agent and to but excluding the date of repayment on one or more bases selected
by the Borrower from among the interest rate Options set forth below. Subject to
the provisions of this Agreement the Borrower may select different Options to
apply simultaneously to different Portions of the Loans and may select different
Funding Segments to apply simultaneously to different parts of the CD Rate
Portion or the Euro-Rate Portion of the Loans. Each selection of a rate Option
shall apply separately and without overlap to the Revolving Credit Loans as a
class. The aggregate number of Funding Segments applicable to the CD Rate
Portion and the Euro-Rate Portion of the Revolving Credit Loans at any time
shall not exceed six unless otherwise permitted by the Agent.

                  (i) Base Rate Option: A rate per annum (computed on the basis
         of a year of 365 or 366 days and actual days elapsed) for each day
         equal to the Base Rate for such day plus the Applicable Margin for such
         day. The "Base Rate" for any day shall mean the greater of (A) the
         Prime Rate for such day or (B) 0.50% plus the Federal Funds Effective
         Rate for such day, such interest rate to change automatically from time
         to time effective as of the effective date of each change in the Prime
         Rate or the Federal Funds Effective Rate.

                  (ii) CD Rate Option: A rate per annum (based on a year of 360
         days and actual days elapsed) for each day equal to the CD Rate for
         such day plus the Applicable Margin for such day. "CD Rate" for any day
         shall mean for each Funding Segment of the CD Rate Portion
         corresponding to a proposed or existing CD Rate Funding Period the rate
         per annum determined by the Agent by adding

                           (A) the rate per annum (which shall be the same for
                  each day in such CD Rate Funding Period) determined

                                      -18-



         in good faith by the Agent in accordance with its usual procedures
         (which determination shall be conclusive absent manifest error) to be
         the arithmetic average of the rates offered to the Reference Banks at
         or about 11:00 a.m., Eastern time, on the first day of such CD Rate
         Funding Period by dealers of recognized standing in negotiable
         certificates of deposit for the purchase at face value of negotiable
         certificates of deposit of major money center banks for delivery on
         such day in amounts comparable to such Funding Segment and having
         maturities comparable to such CD Rate Funding Period plus

                 (B) the Assessment Rate.

         "Assessment Rate" for any day shall mean the rate per annum (rounded
upward to the nearest 1/100 of 1%) determined in good faith by the Agent in
accordance with its usual procedures (which determination shall be conclusive
absent manifest error) to be the maximum effective rate per annum payable by a
depository institution insured by the Federal Deposit Insurance Corporation (or
any successor) for such day as an assessment for insurance on Dollar time
deposits, exclusive of any credit that is or may be allowed against such
assessment on account of assessment payments made or to be made by such
depository institution. The CD Rate shall be adjusted automatically as of the
effective date of each change in the Assessment Rate. The CD Rate Option shall
be calculated in accordance with the foregoing if any Lender is actually
required to pay FDIC assessments or, if required to pay such assessments, is
required to pay such assessments at the "Assessment Rate" as herein defined.

         The Agent shall give prompt notice to the Borrower and to the Lenders
of the CD Rate determined or adjusted in accordance with the definition of CD
Rate, which determination or adjustment shall be conclusive if made in good
faith.

         (iii) Euro-Rate Option: A rate per annum (based on a year of 360 days
and actual days elapsed) for each day equal to the Euro-Rate for such day plus,
in each case, the Applicable Margin for such day. "Euro-Rate" for any day, as
used herein, shall mean for each Funding Segment of the Euro-Rate Portion
corresponding to a proposed or existing Euro-Rate Funding Period the rate per
annum determined by the Agent to be the rate of interest (which shall be the
same for each day in such Euro-Rate Funding Period) determined in good faith by
the Agent in accordance with its usual procedures (which determination shall be
conclusive absent manifest error) to be the average of the rates per annum for
deposits in Dollars offered to the Reference Banks in the London interbank
market at approximately 11:00 a.m., London time,

                                      -19-



         two Business Days prior to the first day of such Euro-Rate Funding
         Period for delivery on the first day of such Euro-Rate Funding Period
         in amounts comparable to such Funding Segment and having maturities
         comparable to such Funding Period.

                  The Agent shall give prompt notice to the Borrower and to the
         Lenders of the Euro-Rate determined in accordance with the definition
         of the Euro-Rate, which determination shall be conclusive if made in
         good faith.

                  (b) Applicable Margins. The "Applicable Margin" and interest
rate Option for any day shall mean the percentage set forth below:



             Interest Rate Option      Applicable Margin
             --------------------      -----------------
                                      
             Base Rate Option              0.000%
             CD Rate Option                0.625%
             Euro-Rate Option              0.500%





provided, however, that the Applicable Margin for each day on which the
Borrower's Consolidated Leverage Ratio is equal to or greater than 1.45:1 (but
less than or equal to 1.55:1) shall mean the percentage set forth below:



             Interest Rate Option       Applicable Margin
             --------------------       -----------------
                                       
             Base Rate Option              0.125%
             CD Rate Option                0.750%
             Euro-Rate Option              0.625%



                  (c) Funding Periods. At any time when the Borrower shall
select, convert to or renew the CD Rate Option or the Euro-Rate Option to apply
to any part of the Loans, the Borrower shall specify one or more periods (the
"Funding Periods") during which each such Option shall apply, such Funding
Periods being as set forth below:

Interest Rate Option                         Available Funding Periods
- --------------------                         -------------------------

CD Rate Option                               30, 60, 90 or 180 days or such
                                             longer period as may be offered by
                                             all of the Lenders ("CD Rate
                                             Funding Period"); and

Euro-Rate Option                             One, two, three or six months or
                                             such longer period as may be
                                             offered by all of the Lenders
                                             ("Euro-Rate Funding Period");


                                      -20-



provided, that:

                  (i) Each CD Rate Funding Period which would otherwise end on a
         day which is not a Business Day shall be extended to the next
         succeeding Business Day;

                  (ii) Each Euro-Rate Funding Period shall begin on a Business
         Day, and the term "month", when used in connection with a Euro-Rate
         Funding Period, shall be construed in accordance with prevailing
         practices in the interbank eurodollar market at the commencement of
         such Euro-Rate Funding Period, as determined in good faith by the Agent
         (which determination shall be conclusive);

                  (iii) The Borrower may not select a Funding Period that would
         end after the Revolving Credit Maturity Date; and

                  (iv) The Borrower shall, in selecting any Funding Period,
         allow for scheduled mandatory payments of the Loans.

         (d) Transactional Amounts. Every selection of, conversion from,
conversion to or renewal of an interest rate Option and every payment or
prepayment of any Loans shall be in a principal amount such that after giving
effect thereto the aggregate principal amount of the Base Rate Portion of the
Revolving Credit Loans shall be $1,000,000 and integral multiples thereof, and
the aggregate principal amount of each Funding Segment of the CD Rate Portion or
the Euro-Rate Portion of the Revolving Credit Loans shall be $5,000,000 and
integral multiples of $1,000,000 thereof.

         (e) CD Rate or Euro-Rate Unascertainable; Impracticability. If

                  (i) on any date on which a CD Rate or a Euro-Rate would
         otherwise be set the Agent (in the case of clauses (A) or (B) below)
         shall have determined in good faith (which determination shall be
         conclusive absent manifest error) that:

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

                           (B) a contingency has occurred which materially and
                  adversely affects the secondary market for negotiable
                  certificates of deposit maintained by dealers of recognized
                  standing or the interbank eurodollar market, as the case may
                  be, or

                  (ii) at any time any Lender shall have determined in good
         faith (which determination shall be conclusive absent manifest error)
         that the making, maintenance or funding of any part of the CD Rate
         Portion or the Euro-Rate Portion has


                                      -21-



         been made impracticable or unlawful by compliance by such Lender or a
         Notional Euro-Rate Funding Office in good faith with any Law or
         guideline or interpretation or administration thereof by any
         Governmental Authority charged with the interpretation or
         administration thereof or with any request or directive of any such
         Governmental Authority (whether or not having the force of law);

then, and in any such event, the Agent or such Lender, as the case may be, may
notify the Borrower of such determination (and any Lender giving such notice
shall notify the Agent). Upon such date as shall be specified in such notice
(which shall not be earlier than the date such notice is given), the obligation
of each of the Lenders to allow the Borrower to select, convert to or renew the
CD Rate Option or Euro-Rate Option, as the case may be, shall be suspended until
the Agent or such Lender, as the case may be, shall have later notified the
Borrower (and any Lender giving such notice shall notify the Agent) of the
Agent's or such Lender's determination in good faith (which determination shall
be conclusive absent manifest error) that the circumstance giving rise to such
previous determination no longer exist.

         If any Lender notifies the Borrower of a determination under subsection
(ii) of this Section 2.06(e), the CD Rate Portion or the Euro-Rate Portion, as
the case may be, of the Loans of such Lender (the "Affected Lender") shall,
subject to Section 2.12(b) hereof, automatically be converted to the Base Rate
Option as of the last day of the then current Funding Period with respect to
such Loans (in the case of a determination that the making, maintenance or
funding of any CD Rate Portion or Euro-Rate Portion of such Loans is
impracticable) and the last day on which the making, maintenance or funding of
any CD Rate Portion or Euro-Rate Portion of such Loans is not unlawful (in the
case of a determination that the making, maintenance or funding of any CD Rate
Portion or Euro-Rate Portion of such Loans is unlawful) and accrued interest
thereon shall be due and payable on such date.

         If at the time the Agent or a Lender makes a determination under
subsection (i) or (ii) of this Section 2.06(e), the Borrower previously has
notified the Agent that it wishes to select, convert to or renew the CD Rate
Option or the Euro-Rate Option, as the case may be, with respect to any proposed
Loans but such Loans have not yet been made, such notification shall be deemed
to provide for selection of, conversion to or renewal of the Base Rate Option
instead of the CD Rate Option or the Euro-Rate Option, as the case may be, with
respect to such Loans or, in the case of a determination by a Lender, such Loans
of such Lender.

         2.07. Conversion or Renewal of Interest Rate Options.

         (a) Conversion or Renewal. Subject to the provisions of Section 2.12(b)
hereof, so long as no Event of Default or



                                      -22-



Potential Default shall have occurred or be continuing hereunder, the Borrower
may convert any part of its Loans from any interest rate Option or Options to
one or more different interest rate Options and may renew the CD Rate Option or
the Euro-Rate Option as to any Funding Segment of the CD Rate Portion or the
Euro-Rate Portion:

                  (i) At any time with respect to conversion from the Base Rate
         Option; or

                  (ii) At the expiration of any Funding Period with respect to
         conversions from or renewals of the CD Rate Option or the Euro-Rate
         Option, as the case may be, as to the Funding Segment corresponding to
         such expiring Funding Period.

Whenever the Borrower desires to convert or renew any interest rate Option or
Options, the Borrower shall provide to the Agent Standard Notice setting forth
the following information:

                  (w) The date, which shall be a Business Day, on which the
         proposed conversion or renewal is to be made;

                  (x) The principal amounts selected in accordance with Section
         2.06(d) hereof of the Base Rate Portion and each Funding Segment of the
         CD Rate Portion and the Euro-Rate Portion, as the case may be, to be
         converted from or renewed;

                  (y) The interest rate Option or Options selected in accordance
         with Section 2.06(a) hereof and the principal amounts selected in
         accordance with Section 2.06(d) hereof of the Base Rate Portion and
         each Funding Segment of the CD Rate Portion and the Euro-Rate Portion,
         as the case may be, to be converted to; and

                  (z) With respect to each Funding Segment to be converted to or
         renewed, the Funding Period selected in accordance with Section 2.06(c)
         hereof to apply to such Funding Segment.

Standard Notice having been so provided, on and after the date specified in such
Standard Notice, interest shall be calculated upon the principal amount of the
Loans as so converted or renewed. Interest on the principal amount of any part
of the Loans converted or renewed (automatically or otherwise) shall be due and
payable on the conversion or renewal date.

                  (b) Failure to Convert or Renew. Absent payment of a Loan or
due notice from the Borrower of conversion or renewal in the circumstances
described in Section 2.07(a)(ii) hereof, any part of the CD Rate Portion or
Euro-Rate Portion for which such notice is not received shall be converted
automatically to the Base Rate Option on the last day of the expiring Funding
Period.


                                      -23-




         2.08. Prepayments Generally. Whenever the Borrower desires or is
required to prepay any part of its Loans, it shall provide Standard Notice to
the Agent setting forth the following information:

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

                  (b) The total principal amount of such prepayment, which shall
         be the sum of the principal amounts selected pursuant to clause (c) of
         this Section 2.08; and

                  (c) The principal amounts selected in accordance with Section
         2.06(d) hereof of the Base Rate Portion and each part of each Funding
         Segment of the CD Rate Portion and the Euro-Rate Portion, as the case
         may be, to be prepaid.

Standard Notice having been so provided, on the date specified in such Standard
Notice, the principal amounts of the Base Rate Portion and each part of the CD
Rate Portion and the Euro-Rate Portion specified in such notice, together with
interest on each such principal amount to such date, shall be due and payable.

         2.09. Prepayments. (a) The Borrower shall have the right at its option
from time to time to prepay its Revolving Credit Loans in whole or part without
premium or penalty (subject, however, in the case of clause (iii) below, to
Section 2.12(b) hereof):

                  (i) At any time (other than a time when Standard Notice
         requesting the making of Revolving Credit Loans bearing interest under
         the Euro-Rate Option has been given by the Borrower but such Loans have
         not yet been made) with respect to any part of the Base Rate Portion;

                  (ii) At the expiration of any Funding Period with respect to
         prepayment of the CD Rate Portion or the Euro-Rate Portion, as the case
         may be, with respect to any part of the Funding Segment corresponding
         to such expiring Funding Period; or

                  (iii) Prior to the expiration of any Funding Period with
         respect to prepayment of the CD Rate Portion or the Euro-Rate Portion,
         as the case may be, with respect to any part of the Funding Segment
         corresponding to such expiring Funding Period, upon payment of the
         indemnity payment set forth in Section 2.12(b) hereof.

         (b) All prepayments shall be made in accordance with Section 2.08
hereof.



                                      -24-



         2.10. Interest Payment Dates. Interest on the Base Rate Portion shall
be due and payable on the date of any conversion of all or part of the Base Rate
Portion to a different interest rate Option, any prepayment of any part of the
Base Rate Portion on the amount prepaid, and on each Regular Payment Date.
Interest on each Funding Segment of the CD Rate Portion shall be due and payable
on the last day of the corresponding CD Rate Funding Period and, if such CD Rate
Funding Period is longer than 90 days, also every 90th day during such CD Rate
Funding Period. Interest on each Funding Segment of the Euro-Rate Portion shall
be due and payable on the last day of the corresponding Euro-Rate Funding Period
and, if such Euro-Rate Funding Period is longer than three months, also on the
last day of every third month during such Funding Period. After maturity of any
part of the Loans (by acceleration or otherwise), interest on such part of the
Loans shall be due and payable on demand.

         2.11. Pro Rata Treatment; Payments Generally.

         (a) Pro Rata Treatment. Each borrowing of Revolving Credit Loans
hereunder and each conversion and renewal of interest rate Options hereunder
shall be made, and all payments made in respect of principal, interest and fees
due from the Borrower hereunder or under the Notes shall be applied, Pro Rata
from and to each Lender, except for payments of agency and arrangement fees
pursuant to Section 2.02(c) hereof, payments of interest involving an Affected
Lender as provided in Section 2.06(e) hereof and payments to a Lender subject to
a withholding deduction under Section 2.14(c) hereof. The failure of any Lender
to make a Revolving Credit Loan shall not relieve any other Lender of its
obligation to lend hereunder, but neither the Agent nor any Lender shall be
responsible for the failure of any other Lender to make a Revolving Credit Loan.

                  (b) Payments Generally. All payments and prepayments to be
made by the Borrower in respect of principal, interest, fees, indemnity,
expenses or other amounts due from the Borrower to the Agent for the account of
the Lenders hereunder or under any Loan Document in Dollars shall be payable at
2:00 p.m., Pittsburgh time, on the day when due without presentment, demand,
protest or notice of any kind, all of which are hereby expressly waived, and an
action therefor shall immediately accrue, without setoff, counterclaim,
withholding or other deduction of any kind or nature, except for payments to a
Lender subject to a withholding deduction under Section 2.14(c) hereof. Except
for payments under Sections 2.12 and 9.06 hereof, such payments shall be made to
the Agent at its Office in Dollars in funds immediately available at such
Office, and payments under Sections 2.12 and 9.06 hereof shall be made to the
applicable Lender at such domestic account as it shall specify to the Borrower
from time to time in funds immediately available at such account. Any payment or
prepayment received by the Agent or such Lender after 2:00 p.m., Pittsburgh
time, on any day shall be deemed to have been received on the next



                                      -25-



succeeding Business Day. The Agent shall distribute to the Lenders all such
payments received by it from the Borrower as promptly as practicable after
receipt by the Agent.

          (c) Interest on Overdue Amounts. To the extent permitted by law, after
there shall have become due (by acceleration or otherwise) principal, interest,
fees, indemnity, expenses or any other amounts due from the Borrower hereunder
or under any other Loan Document, such amounts shall bear interest for each day
until paid (before and after judgment), payable on demand, at a rate per annum
based on a year of 365 or 366 days, as the case may be, and actual days elapsed
(in the case of any Portion of Loans bearing interest at the Base Rate Option)
and 360 days and actual days elapsed (in the case of any Portion of Loans
bearing interest at the CD Rate Option or the Euro-Rate Option) which for each
day shall be equal to the following:

                  (i) In the case of any part of the CD Rate Portion or
         Euro-Rate Portion of any Loans, (A) until the end of the applicable
         then-current Funding Period at a rate per annum 200 basis points above
         the rate otherwise applicable to such part, and (B) thereafter in
         accordance with the following clause (ii); and

                  (ii) In the case of any other amount due from the Borrower
         hereunder or under any Loan Document, 200 basis points above the then
         current Base Rate.

                  2.12. Additional Compensation in Certain Circumstances.

         (a) Increased Costs or Reduced Return Resulting From Taxes, Reserves,
Capital Adequacy Requirements, Expenses, Etc. If any Law or change therein or
guideline or interpretation or application thereof by any Governmental Authority
charged with the interpretation or administration thereof or compliance with any
request or directive of any Governmental Authority (whether or not having the
force of law) adopted or made after the date hereof:

                  (i) subjects any Lender or any Notional Euro-Rate Funding
         Office 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 fee or other amounts due from the
         Borrower hereunder or under the Notes (except for taxes on the overall
         net income or overall gross receipts of such Lender or such Notional
         Euro-Rate Funding Office imposed by the jurisdictions (federal, state
         and local) in which the Lender's principal office or Notional Euro-Rate
         Funding Office is located),

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



                                      -26-



         acquisitions of funds by, such Lender or any Notional Euro-Rate Funding
         Office (other than requirements expressly included herein in the
         determination of the CD Rate, the Euro-Rate, or the determination of
         additional interest pursuant to Section 2.12(c) hereof, as the case may
         be, hereunder),

                  (iii) imposes, modifies or deems applicable any capital
         adequacy or similar requirement (A) against assets (funded or
         contingent) of, or credits or commitments to extend credit extended by,
         any Lender or any Notional Euro-Rate Funding Office, or (B) otherwise
         applicable to the obligations of any Lender or any Notional Euro-Rate
         Funding Office under this Agreement, or

                  (iv) imposes upon any Lender or any Notional Euro-Rate Funding
         Office any other condition or expense directly related to this
         Agreement, the Notes or its making, maintenance or funding of any Loan

and the result of any of the foregoing is determined by any Lender to increase
the cost to, reduce the income receivable by, or impose any expense (including
loss of margin) upon such Lender, any Notional Euro-Rate Funding Office or, in
the case of clause (iii) hereof, any Person controlling a Lender, with respect
to this Agreement, the Notes or the making, maintenance or funding of any Loan
(or, in the case of any capital adequacy or similar requirement, to have the
effect of reducing the rate of return on such Lender's or controlling Person's
capital, taking into consideration such Lender's or controlling Person's
policies with respect to capital adequacy) by an amount which such Lender deems
to be material (such Lender being deemed for this purpose to have made,
maintained or funded each Funding Segment of the CD Rate Portion and the
Euro-Rate Portion from a Corresponding Source of Funds), such Lender may from
time to time promptly notify the Borrower of the amount determined in good faith
(using any averaging and attribution methods) by such Lender (which
determination shall be conclusive absent manifest error) to be necessary to
compensate such Lender or such Notional Euro-Rate Funding Office for such
increase, reduction or imposition. Each Lender will notify the Borrower and the
Agent of any event occurring after the date of this Agreement which will entitle
such Lender to compensation pursuant to this Section 2.12 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation. Each Lender will furnish the Borrower and Agent with a statement
setting forth in reasonable detail the basis, the manner of calculation and the
amount of each request by such Lender for compensation from the Borrower under
this Section 2.12. Such amount shall be due and payable by the Borrower to such
Lender 20 days after such notice is given.


                                      -27-


          (b) Funding Breakage. In addition to the compensation required under
Section 2.12(a) hereof, the Borrower shall indemnify each Lender against any
loss or expense (including loss of margin) which such Lender has incurred as a
consequence of:

                  (i) any payment, prepayment or conversion of any part of any
         Funding Segment of any CD Rate Portion or Euro-Rate Portion of the
         Loans on a day other than the last day of the corresponding Funding
         Period (whether or not such payment, prepayment or conversion is
         mandatory or automatic and whether or not such payment or prepayment is
         then due),

                  (ii) any attempt by the Borrower to revoke (expressly, by
         later inconsistent notices or otherwise) in whole or in part any notice
         stated herein to be irrevocable (the Agent having in its sole
         discretion the options (A) to give effect to such attempted revocation
         provided that indemnity under this Section 2.12(b) is obtained or (B)
         to treat such attempted revocation as having no force or effect, as if
         never made), or

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

          If any Lender sustains or incurs any such loss or expense it shall
from time to time notify the Borrower and the Agent in writing setting forth in
reasonable detail the amount determined in good faith by such Lender (which
determination shall be conclusive absent manifest error) to be necessary to
indemnify such Lender for such loss or expense. Such amount shall be due and
payable by the Borrower to the Agent for the account of such Lender, 20 days
after such notice is given.

                  (c) Additional Interest. (i) So long as any Lender shall be
         required under regulations of the Board of Governors of the Federal
         Reserve System to maintain reserves with respect to liabilities or
         assets consisting of or including loans made with reference to the CD
         Rate, such Lender may require the Borrower to pay, but only in respect
         of any period during which such reserves shall actually be maintained
         by such Lender, additional interest on the unpaid principal amount of
         the CD Rate Portion of the Loans, at an interest rate per annum equal
         at all times during each CD Rate Funding Period to the difference
         obtained by subtracting (A) the CD Rate for such CD Rate Funding Period
         from (B) the rate obtained by dividing such CD Rate referred to in
         clause (A) above by that percentage equal to 100% minus the CD Rate
         Reserve Percentage of such Lender for such CD Rate Funding Period.



                                      -28-



                  (ii) So long as any Lender shall be required under regulations
         of the Board of Governors of the Federal Reserve System to maintain
         reserves with respect to liabilities or assets consisting of or
         including Eurocurrency Liabilities, such Lender may require the
         Borrower to pay, but only in respect of any period during which such
         reserves shall actually be maintained by such Lender, additional
         interest on the unpaid principal amount of the Euro-Rate Portion of the
         Loans, at an interest rate per annum equal at all times during each
         Euro-Rate Funding Period to the difference obtained by subtracting (A)
         the Euro-Rate for such Euro-Rate Funding Period from (B) the rate
         obtained by dividing such Euro-Rate referred to in clause (A) above by
         that percentage equal to 100% minus the Euro-Rate Reserve Percentage of
         such Lender for such Euro-Rate Funding Period.

                  (iii) If any Lender shall claim entitlement to any additional
         amount pursuant to this Section 2.12(c), then such Lender shall deliver
         to the Borrower a certificate setting forth the basis for the
         determination thereof as promptly as practicable. More than one such
         certificate may be so delivered. Each such certificate shall be
         conclusive and binding for all purposes as to the amount due absent
         manifest error. The Borrower shall pay to such Lender the amount shown
         as due on any such certificate within 20 days after its receipt of the
         same.

         2.13. HLT Classification. The Agent shall promptly give notice to the
Borrower and each Lender if at any time

         (a) the Agent determines in its reasonable judgment (based upon any Law
or guideline or interpretation or application thereof by any Governmental
Authority charged with the interpretation or administration thereof or
compliance with any request or directive of any Governmental Authority (whether
or not having the force of law), now existing or hereafter adopted), that any
portion of the Loans under this Agreement should be classified as a "highly
leveraged transaction" (or any similar or successor classification then in
effect) (an "HLT Classification"),

         (b) the Agent is informed by any Governmental Authority that any
portion of the Loans under this Agreement are or should be subject to HLT
Classification, or

         (c) any Lender is informed by any Governmental Authority that any
portion of the Loans under this Agreement contemplated hereby are or should be
subject to HLT Classification, and such Lender in its discretion gives notice of
such fact to the Agent.


                                      -29-



In such event the parties hereto shall commence negotiations in good faith with
a view to agreeing on revised interest rates, fees and other terms and
conditions hereof, consistent with then-current market requirements for
transactions subject to HLT Classification. If the parties hereto fail to agree
on such matters in their respective absolute discretion within 30 days of the
notice given by the Agent referred to above, then the Agent, acting at the
request of the Required Lenders, may give a further notice to the Borrower, and
effective as of the date of such further notice (i) each Applicable Margin set
forth in Section 2.06(b) hereof shall be increased by 2.50%, and (ii) the
percentage applicable to calculation of the Revolving Credit Commitment Fee in
Section 2.02(a) hereof shall be increased by .250%. Except as set forth above,
this Agreement shall remain in full force and effect.

         2.14 Taxes.

         (a) Payments Net of Taxes. All payments made by the Borrower under this
Agreement shall be made free and clear of, and without reduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, and all liabilities with respect thereto, excluding

                  (i) in the case of the Agent and each Lender, income or
         franchise taxes imposed on the Agent or such Lender by the jurisdiction
         under the laws of which the Agent or such Lender is organized or any
         political subdivision or taxing authority thereof or therein or as a
         result of a connection between such Lender and any jurisdiction other
         than a connection resulting solely from this Agreement and the
         transactions contemplated hereby, and

                  (ii) in the case of each Lender, income or franchise taxes
         imposed by any jurisdiction in which such Lender's lending offices
         which make or book Loans are located or any political subdivision or
         taxing authority thereof or therein

(all such non-excluded taxes, levies, imposts, deductions, charges or
withholdings being hereinafter called "Taxes"). If any Taxes are required to be
withheld or deducted from any amounts payable to the Agent or any Lender under
this Agreement or any other Loan Document, the Borrower shall pay the relevant
amount of such Taxes and the amounts so payable to the Agent or such Lender
shall be increased to the extent necessary to yield to the Agent or such Lender
(after payment of all Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement and the
other Loan Documents. Whenever any Taxes are paid by the Borrower with respect
to payments made in connection with this Agreement, as promptly as possible

                                      -30-



thereafter, the Borrower shall send to the Agent for its own account or for the
account of such Lender, as the case may be, a certified copy of an original
official receipt received by the Borrower showing payment thereof.

          (b) Indemnity. The Borrower hereby indemnifies the Agent and each of
the Lenders for the full amount of all Taxes attributable to payments by or on
behalf of the Borrower hereunder or under any of the other Loan Documents, any
such Taxes paid by the Agent or such Lender, as the case may be, any present or
future claims, liabilities or losses with respect to or resulting from any
omission to pay or delay in paying any Taxes (including any incremental Taxes,
interest or penalties that may become payable by the Agent or such Lender as a
result of any failure to pay such Taxes), whether or not such Taxes were
correctly or legally asserted. Such indemnification shall be made within 30 days
from the date such Lender or the Agent, as the case may be, makes written demand
therefor.

          (c) Withholding and Backup Withholding. Each Lender that is
incorporated or organized under the laws of any jurisdiction other than the
United States or any State thereof agrees that, on or prior to the Closing Date
(or, with respect to any Lender which becomes a party to this Agreement pursuant
to Section 9.14 hereof, the Transfer Effective Date), it will furnish to the
Borrower and the Agent

                  (i) two valid, duly completed copies of United States Internal
         Revenue Service Form 4224 or United States Internal Revenue Form 1001
         or successor applicable form, as the case may be, certifying in each
         case that such Lender is entitled to receive payments under this
         Agreement and the other Loan Documents without deduction or withholding
         of any United States federal income taxes, and

                  (ii) a valid, duly completed Internal Revenue Service Form W-8
         or W-9 or successor applicable form, as the case may be, to establish
         an exemption from United States backup withholding tax.

Each Lender which so delivers to the Borrower and the Agent a Form 1001 or 4224
and Form W-8 or W-9 applicable forms (the "Forms") agrees to deliver to the
Borrower and the Agent two further copies of the Forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or otherwise is required to be resubmitted as a
condition to obtaining an exemption from withholding tax, or after the
occurrence of any event requiring a change in the most recent form previously
delivered by it, and such extensions or renewals thereof as may reasonably be
requested by the Borrower and the Agent, certifying in the case of a Form 1001
or Form 4224 that such Lender is entitled to receive payments under this
Agreement or any other Loan Document without deduction or

                                      -31-



withholding of any United States federal income taxes, unless in any such cases
an event (including any changes in Law) has occurred prior to the date on which
any such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Lender from duly completing and
delivering any such letter or form with respect to it and such Lender advises
the Borrower and the Agent that it is not capable of receiving payments without
any deduction or withholding of United States federal income tax, and in the
case of a Form W-8 or W-9, establishing an exemption from United States backup
withholding tax. Notwithstanding anything to the contrary contained herein, the
Borrower shall not be required to pay any additional amounts pursuant to this
Section 2.14 or pursuant to Section 2.12 if the obligation to pay such
additional amounts would not have arisen but for the failure by any Lender to
comply with its obligations hereunder, or if such Lender shall have delivered
the appropriate Forms and such Lender is not entitled to exemption from
deduction or withholding of U.S. federal income tax in respect of payments made
by the Borrower hereunder for any reason other than a change in U.S. law or
regulations or in the official interpretation thereof after the date of delivery
of such Forms.

         2.15. Funding by Branch, Subsidiary or Affiliate.

         (a) Notional Funding. Each Lender shall have the right from time to
time, prospectively or retrospectively, without notice to the Borrower, to deem
any branch, subsidiary or affiliate of such Lender to have made, maintained or
funded any part of the Euro-Rate Portion at any time. Any branch, subsidiary or
affiliate so deemed shall be known as a "Notional Euro-Rate Funding Office."
Such Lender shall deem any part of the Euro-Rate Portion of the Loans or the
funding therefor to have been transferred to a different Notional Euro-Rate
Funding Office if such transfer would avoid or cure an event or condition
described in Section 2.06(e)(ii) hereof or would lessen compensation payable by
the Borrower under Sections 2.12(a) or 2.14(b) hereof, and provided that such
Lender determines in its sole discretion that such transfer would be practicable
and would not have a material adverse effect on such part of the Loans, such
Lender or any Notional Euro-Rate Funding Office (it being assumed for purposes
of such determination that each part of the Euro-Rate Portion is actually made
or maintained by or funded through the corresponding Notional Euro-Rate Funding
Office). Notional Euro-Rate Funding Offices may be selected by such Lender
without regard to such Lender's actual methods of making, maintaining or funding
Loans or any sources of funding actually used by or available to such Lender.

         (b) Actual Funding. Each Lender shall have the right from time to time
to make or maintain any part of the Euro-Rate Portion by arranging for a branch,
subsidiary or affiliate of such Lender to make or maintain such part of the
Euro-Rate Portion.


                                      -32-


Such Lender shall have the right to (i) hold any applicable Note payable to its
order for the benefit and account of such branch, subsidiary or affiliate or
(ii) request the Borrower to issue one or more promissory notes in the principal
amount of such Euro-Rate Portion, in substantially the form attached hereto as
Exhibit A with the blanks appropriately filled, payable to such branch,
subsidiary or affiliate and with appropriate changes reflecting that the holder
thereof is not obligated to make any additional Loans to the Borrower. The
Borrower agrees to comply promptly with any request under subsection (ii) of
this Section 2.15(b). If any Lender causes a branch, subsidiary or affiliate to
make or maintain any part of the Euro-Rate Portion hereunder, all terms and
conditions of this Agreement shall, except where the context clearly requires
otherwise, be applicable to such part of the Euro-Rate Portion and to any note
payable to the order of such branch, subsidiary or affiliate to the same extent
as if such part of the Euro-Rate Portion were made or maintained and such note
were a Revolving Credit Note payable to such Lender's order.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

         The Borrower hereby represents and warrants to the Agent and each
Lender as follows:

         3.01. Corporate Status. The Borrower and each Subsidiary thereof (a)
is a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation; (b) has corporate power and authority
to own its property and to transact the business in which it is engaged or
presently proposes to engage; and (c) is duly qualified to do business as a
foreign corporation and is in good standing in all jurisdictions in which the
ownership of its properties or the nature of its activities or both makes such
qualification necessary, except for matters that, individually or in the
aggregate, could not have a Material Adverse Effect. Schedule 3.01 hereof states
as of the date hereof the jurisdiction of incorporation of the Borrower and each
Subsidiary.

         3.02. Corporate Power and Authorization. The Borrower has the corporate
power to execute, deliver and perform the Loan Documents to be executed by it,
has the power to borrow hereunder and has taken all necessary corporate action
and obtained all necessary consents and approvals to authorize the borrowings
hereunder on the terms and conditions of this Agreement, has taken all necessary
action, corporate or otherwise, to authorize the execution, delivery and
performance of this Agreement and the other Loan Documents to be executed by it.
No consent or approval of stockholders of the Borrower generally, no consent or
approval of any landlord or mortgagee, and no waiver of any Lien of right or
distraint or other similar right, is or will be required in


                                      -33-



connection with the execution, delivery or performance by it, or the validity,
enforcement or priority, of the Loan Documents to be executed by it.

         3.03. Execution and Bindinq Effect. This Agreement and each other Loan
Document to which the Borrower is a party has been, or upon its execution and
delivery will be, duly executed and delivered by the Borrower and each
constitutes, or upon its execution and delivery will constitute, the valid and
legally binding obligation of the Borrower, enforceable in accordance with its
terms, except as such enforcement may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, or other similar laws, now or hereafter
in effect, relating to or affecting the enforcement of creditors' rights
generally and except that the remedy of specific performance and other equitable
remedies are subject to judicial discretion. There is no action, suit,
proceeding or investigation pending or, to the knowledge of the Borrower,
threatened against or affecting the Borrower or any of its Subsidiaries which
questions the validity or the enforceability of any of the Loan Documents.

         3.04. Governmental Approvals and Filings. No approval, order, consent,
authorization, certificate, license, permit or validation of, or exemption or
other action by, or filing, recording or registration with, or notice to, any

necessary or advisable in connection with execution and delivery of this
Agreement or any other Loan Document, consummation by the Borrower of the
transactions herein or therein contemplated, or performance of or compliance
with the terms and conditions hereof or thereof. Neither the Borrower nor any
Subsidiary thereof is subject to regulation under the Public Utility Holding
Company Act of 1935, the Federal Power Act or the Investment Company Act of 1940
or to any Federal or state statute or regulation limiting the Borrower's ability
to incur Indebtedness for money borrowed. Neither the Borrower nor any
Subsidiary thereof is an "investment company" or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

         3.05. Absence of Conflicts. The execution and delivery by the Borrower
of this Agreement and each other Loan Document to which it is a party and
performance by it hereunder and thereunder, will not violate any Law (including,
without limitation, Regulations G, U, T and X of the Federal Reserve Board) and
will not conflict with or result in a breach of any order, writ, injunction,
ordinance, resolution, decree, or other similar document or instrument of any
court or governmental authority, bureau or agency, domestic or foreign, or its
certificate of incorporation or by-laws or create (with or without the giving of
notice or lapse of time, or both) a default under or breach of any agreement,
bond, note or indenture to which it is a party (by successor in interest or
otherwise), or by which it is

                                      -34-



bound or any of its properties or assets is affected, or result in the
imposition of any Lien of any nature whatsoever upon any of the properties or
assets owned by or used in connection with the business of the Borrower or any
of its Subsidiaries.

         3.06. Audited Financial Statements. The Borrower has heretofore
furnished to the Agent and each Lender consolidated balance sheets of the
Borrower and its consolidated Subsidiaries as of December 31, 1990 and the
related consolidated statements of income, cash flows and changes in
stockholders' equity for the fiscal year then ended, as examined and reported on
by Ernst & Young, independent certified public accountants for the Borrower, who
delivered an unqualified opinion in respect thereof. Such financial statements
(including the notes thereto) present fairly the financial condition of the
Borrower and its consolidated Subsidiaries as of the end of each such fiscal
year and the results of their operations and their cash flows for the fiscal
years then ended, all in conformity with GAAP.

         3.07. Absence of Undisclosed Material Liabilities. Except as disclosed
in writing by the Borrower to the Lenders and except as to the possible effect
of the application of FAS 106, neither the Borrower nor any Subsidiary of the
Borrower has any liability or obligation of any nature whatever (including
without limitation Environmental Matters) which, to the knowledge of any
Responsible Officer, will more likely than not have a Material Adverse Effect.
As of September 30, 1991, neither the Borrower nor any Subsidiary of the
Borrower has any Indebtedness other than the Indebtedness of the Borrower and
its Subsidiaries set forth on Schedule 3.07 hereto.

         3.08. Absence of Material Adverse Change. Except as to the possible
effect of the application of FAS 106, since December 31, 1990, there has been no
change in the business, properties, assets or financial condition of the
Borrower and its Subsidiaries taken as a whole which is likely to have a
Material Adverse Effect.

         3.09. Accurate and Complete Disclosure. The Borrower has furnished to
the Lenders copies of its Annual Report on Form 10-K for the fiscal year ended
December 31, 1990, its Quarterly Report on Form 10-Q for the quarter ended June
30, 1991 and its Annual Report for the year ended December 31, 1990. None of
such documents contains any untrue statement of a material fact or omits to
state any material fact necessary to make such information (taken as a whole)
not misleading at such time in light of the circumstances in which it was
provided.

         3.10. Margin Regulations. No part of the proceeds of any Loan hereunder
will be used for the purpose of buying or carrying any "margin stock", as such
term is used in Regulations G and U of the Board of Governors of the Federal
Reserve System, as amended from time to time, except margin stock issued by the

                                      -35-



Borrower, or to extend credit to others for the purpose of buying or carrying
any "margin stock." Neither the Borrower nor any Subsidiary thereof is engaged
in the business of extending credit to others for the purpose of buying or
carrying "margin stock." Neither the making of any Loan nor any use of proceeds
of any such Loan will violate or conflict with the provisions of Regulation G,
T, U or X of the Board of Governors of the Federal Reserve System, as amended
from time to time.

         3.11. Subsidiaries. Schedule 3.11 hereof states as of the Closing Date
each Subsidiary of the Borrower and the percentage of outstanding shares owned
by the Borrower and by each Subsidiary. The outstanding shares of each
Subsidiary of the Borrower have been duly authorized and validly issued and are
fully paid and nonassessable. The Borrower and each Subsidiary thereof owns
beneficially and of record and has good title to all of the shares represented
by the ownership percentage shown in such Schedule 3.11, free and clear of any
Lien. There are no options, warrants, calls, subscriptions, conversion rights,
exchange rights, preemptive rights or other rights, agreements or arrangements
(contingent or otherwise) which may in any circumstances now or hereafter
obligate any Subsidiary to issue any shares of its capital stock or any other
securities. As of the Closing Date, no Subsidiary has outstanding any class of
preferred stock or any class of common stock with a prior right to dividends.

          3.12. Partnerships, etc. As of the Closing Date, neither the Borrower
nor any Subsidiary thereof is a partner (general or limited) of any partnership,
is a party to any joint venture or owns (beneficially or of record) any material
equity or similar interest in any Person (including but not limited to any
interest pursuant to which the Borrower or such Subsidiary has or may in any
circumstance have an obligation to make capital contributions to, or be
generally liable for or on account of the liabilities, acts or omissions of such
other Person), except for the partnership interests set forth in Schedule 3.12
hereof.

         3.13. Litigation. Except as disclosed in writing by the Borrower to the
Lenders, there is no pending or (to the Borrower's knowledge) threatened action,
suit, proceeding or investigation by or before any Governmental Authority
against or affecting the Borrower or any Subsidiary of the Borrower, which will
more likely than not, individually or in the aggregate, have a Material Adverse
Effect.

         3.14. Absence of Events of Default. No event has occurred and is
continuing and no condition exists which constitutes an Event of Default or
Potential Default.

         3.15. Insurance. The policies, binders or self-insurance programs for
fire, liability, product liability, worker's compensation, vehicular and other
insurance currently



                                      -36-



held by or on behalf of the Borrower and each Subsidiary thereof insure its
properties and business activities against such losses and risks as are adequate
to protect its properties in accordance with customary industry practice when
entered into or renewed. To the best knowledge of the Borrower, all such
policies, binders and self-insurance programs are in full force and effect.
Neither the Borrower nor, to the best knowledge of the Borrower, any of its
Subsidiaries has received notice from any insurer or agent of such insurer that
substantial capital improvements or other expenditures will have to be made in
order to continue such insurance and, to the best knowledge of the Borrower, no
such improvements or expenditures are required. Neither the Borrower nor, to the
best knowledge of the Borrower, any of its Subsidiaries has received notice of
cancellation of any material insurance policy or binder.


         3.16. Title to Properties. Except where the failure to possess good and
marketable title in fee simple or good title, as the case may be, would not have
a Material Adverse Effect, the Borrower and each Subsidiary thereof has good and
marketable title in fee simple to all real property owned or purported to be
owned by it and necessary for the operation of its business and good title to
all other property of whatever nature owned or purported to be owned by it,
including but not limited to all property reflected in the most recent audited
balance sheet referred to in Section 3.06 hereof or submitted pursuant to
Section 5.01(a) hereof, as the case may be (except as sold or otherwise disposed
of in the ordinary course of business after the date of such balance sheet or,
after the Closing Date, as otherwise expressly permitted by the Loan Documents)
in each case free and clear of all Liens, other than Liens permitted by Section
6.02 hereof.

         3.17. Intellectual Property. The Borrower and each Subsidiary thereof
owns, or is licensed or otherwise has the right to use, all the patents,
trademarks, service marks, names (trade, service, fictitious or otherwise),
copyrights, technology (including but not limited to computer programs and
software), processes, data bases and other rights, free from burdensome
restrictions, necessary to own and operate its properties and to carry on its
business as presently conducted and presently planned to be conducted without
conflict with the rights of others.

         3.18. Taxes. Consolidated federal income tax returns for the Borrower
and its domestic Subsidiaries have been examined by the IRS for all years up to
and including the year ended December 31, 1987. The Borrower and each of its
Subsidiaries have filed or caused to be filed all federal, state and local tax
returns which, to the knowledge of any Responsible Officer of the Borrower, are
required to be filed and have paid or caused to be paid all taxes as shown on
such returns or on any assessment received by it or by any of them, to the
extent that such taxes have become due, except any such tax or assessment the
validity of which is being contested in good faith by appropriate proceedings


                                      -37-


and with respect to which the Borrower or a Subsidiary of the Borrower, as
appropriate, has set aside on its books adequate reserves to the extent the
Borrower or any Subsidiary of the Borrower and a nationally recognized
independent certified public accountant believes such reserves are necessary. To
the extent that the Borrower in good faith believes is necessary, the Borrower
and its Subsidiaries have set up reserves which are believed by the Borrower to
be adequate for the payment of additional taxes. All assessed deficiencies
resulting from examinations by the IRS up to and including the year ended
December 31, 1987 have been discharged, reserved against or will not impair the
Borrower's ability to repay the Loans.

         3.19. Employee Benefits. (a) No borrowing contemplated by this
Agreement is a transaction which is subject to the prohibitions of Section 406
of ERISA or in connection with which a tax could be imposed pursuant to Section
4975 of the Code or a civil penalty assessed pursuant to Section 502(i) of ERISA
(assuming that monies other than monies representing plan assets are borrowed
hereunder). Neither the Borrower, any of its Subsidiaries nor any other Person,
including any fiduciary, has engaged in any prohibited transaction (as defined
in Section 4975 of the Code or Section 406 of ERISA) which could subject any of
the Benefit Plans, the Borrower, or any Subsidiary (or any entity which they
have an obligation to indemnify) to any tax or penalty imposed under 4975 of the
Code or Section 502(i) of ERISA or any other material liability under a foreign
law of similar nature which alone or together with any other item described in
this Section 3.19 would have a Material Adverse Effect.

         (b) Neither the Borrower nor any of its Subsidiaries (including any
member of their respective Controlled Group) (i) has incurred or expects to
incur any liability under Title IV of ERISA or Section 502(g) of ERISA or any
analogous provision relating to Section 515 of ERISA or (ii) has become subject
or expects to be subject to the lien described in Section 412(n) of the Code,
which alone or together with any other item described in this Section 3.19 would
have a Material Adverse Effect.

         (c) The Pension Plans do not have an "accumulated funding deficiency"
(whether or not waived) within the meaning of Section 412 of the Code or Section
302 of ERISA. No Pension Plan has benefit liabilities as defined in Section
4001(a)(16) of ERISA which exceed the assets of such Pension Plan by such an
amount that the termination of such Pension Plan alone or together with any
other item described in this Section would have a Material Adverse Effect. The
Borrower has received a favorable determination letter from the IRS with respect
to all Pension Plans except for such Pension Plans with respect to which the
failure to receive such a favorable determination would not alone or together
with any other item described in this Section 3.19 have a Material Adverse
Effect and nothing has happened since the date of such letter that has adversely
affected such

                                      -38-



qualification. There is no Lien outstanding or security interest given in
connection with a Pension Plan or under Title IV of ERISA which would exceed the
percentage limitations of Section 6.02(g) hereof. As of the date hereof, the
Borrower has filed all required notices with respect to any terminated Benefit
Plans subject to Title IV of ERISA, no objections relating to any such
termination by the IRS or the PBGC are pending and the time period for making
such objections has lapsed.

          (d) Neither the Borrower nor any of its Subsidiaries (including any
member of their respective Controlled Group) is in default in any material
respect under any Benefit Plan and all Benefit Plans are administered in
accordance with their terms and are in all material respects in compliance with
all applicable Laws, except where any such default or failure to comply would
not alone or together with any other item described in this Section 3.19 have a
Material Adverse Effect.

         3.20 Environmental Matters

         (a) The Borrower and each Subsidiary of the Borrower, to its knowledge,
has been operated in compliance with all applicable Requirements of Law, except
for matters which, individually or in the aggregate, are not likely to have a
Material Adverse Effect.

         (b) The Borrower and each Subsidiary of the Borrower, to its knowledge,
has not received notice from any governmental authority that any of them is a
potentially responsible party under any Requirements of Law at any disposal site
containing Hazardous Materials, nor received any notice that any lien under any
Requirements of Law against any property of the Borrower or Subsidiary of the
Borrower exists, except for matters which, individually or in the aggregate, are
not likely to have a Material Adverse Effect.

                                   ARTICLE IV

         Borrower relative to this Agreement and the other Loan Documents and
         (iii) the incumbency and signature of the respective officers of the
         Borrower executing this Agreement and the other Loan Documents to which

         have received, with a copy for each Lender, certificates from the

         Authorities dated not more than 30 days before the Closing Date showing
         the good standing of the Borrower in its state of incorporation.

         E. Besser, Esquire, General Counsel of the Borrower, in the form
         attached hereto as Exhibit C.

                  (e) Fees, Expenses, etc. All fees and other compensation
         required to be paid to the Agent or the Lenders pursuant hereto or
         pursuant to any other written agreement on or prior to the Closing Date
         shall have been paid or received.

                  (f) Additional Matters. All corporate and other proceedings,
         and all documents, instruments and other matters in connection with the
         transactions contemplated by this Agreement and the other Loan
         Documents shall be reasonably satisfactory in form and substance to the
         Agent and each Lender.

         4.02. Conditions to All Loans. The obligation of each Lender to make

                  (b) Representations and Warranties. Each of the
         representations and warranties made by the Borrower herein shall be
         true and correct in all material respects on and as of such date as if
         made on and as of such date (except with respect to representations and
         warranties which specifically refer to an earlier date, which shall be
         true and correct in all material respects as of such earlier date),
         both before and after giving effect to the Loans requested to be made
         on such date.

                  (c) No Defaults. No Event of Default or Potential Default
         shall have occurred and be continuing on such date or after giving
         effect to the Loans requested to be made on such date.

                  (d) No Violations of Law, etc. Neither the making nor use of
         the Loans shall cause any Lender to violate or conflict with any Law.

warranty by the Borrower that the conditions set forth in this Section 4.02 have
been satisfied as of the date of such request. Failure of the Agent to receive
notice from the Borrower to the contrary before such Loan is made shall
constitute a further representation and warranty by the Borrower that the

such Loan is made.

                                    ARTICLE V
                             AFFIRMATIVE COVENANTS

         The Borrower hereby covenants to the Agent and each Lender as follows:

         5.01. Basic Reporting Requirements.

         (a) Annual Audit Reports. The Borrower shall deliver to the Agent, with
a copy for each Lender, as soon as available, but in any event within 90 days
after the last day of each of its fiscal years, a consolidated balance sheet of
the Borrower as at such last day of the fiscal year, and the related
consolidated statement of income, consolidated statement of changes in common
shareholders equity and consolidated statement of cash flows for such fiscal
year, each prepared in accordance with GAAP (except as required by any change in
accounting principles or concurred in by the Borrower's independent certified
public accountants), in reasonable detail, and, as to the financial statements,
certified without qualification (other than relating to a change in accounting
principles with which such accountants concur and other than any other
qualification which the Agent and the Required Lenders deem, in their reasonable
judgment, to be immaterial) by Ernst & Young or another firm of independent
certified public

                                      -41-



accountants satisfactory to the Agent as fairly presenting the financial
position at year end and the consolidated results of operations of the Borrower
consolidated for the year ending on such date and as having been prepared in
accordance with GAAP.

          (b) Quarterly Consolidated Reports. The Borrower shall deliver to the
Agent, with a copy for each Lender, as soon as available, but in any event
within 60 days after the end of each of the Borrower's fiscal quarterly periods,
a consolidated balance sheet of the Borrower as of the last day of such quarter
and consolidated statement of income, consolidated statement of changes in
common shareholders' equity and consolidated statement of cash flows, for such
quarter, and on a comparative basis figures for the corresponding period of the
immediately preceding fiscal year, all in reasonable detail, each such statement
to be certified in a certificate of a Responsible Officer of the Borrower, as
the case may be, as fairly presenting the financial position and the
consolidated results of operations of the Borrower consolidated for such quarter
and as having been prepared in accordance with GAAP for interim financial
statements (subject to customary year-end audit adjustments).

          (c) Quarterly Compliance Certificates. The Borrower shall deliver to
the Agent, with a copy for each Lender, a Quarterly Compliance Certificate in
substantially the form set forth as Exhibit D hereto, duly completed and signed
by a Responsible Officer of the Borrower concurrently with the delivery of the
financial statements referred to in subsections (a) and (b) of this Section
5.01.
        
         (d) Other Financial Statements. The Borrower shall deliver to the
Agent, with a copy for each Lender, for each Subsidiary and Subsidiary
Investment which is subject to any restriction on its ability to make Stock
Payments in respect of its capital stock (except for restrictions applicable to
corporations generally in such entity's place of incorporation) and in which
there has been an investment of cash or assets since the Closing Date, as soon
as possible but in any event within 90 days after the end of each fiscal year, a
certificate, duly executed by a Responsible Officer of the Borrower, as to
amount of the Borrower's investment, direct or indirect, in each Subsidiary and
Subsidiary Investment, together with a balance sheet and an income statement for
each Subsidiary subject to any such restriction.

         (e) Certain Other Reports and Information. Promptly upon their becoming
available to the Borrower, the Borrower shall deliver to the Agent, with a copy
for each Lender, a copy of (i) all regular or special reports, registration
statements and amendments to the foregoing which the Borrower or any Subsidiary
shall file with the Securities and Exchange Commission (or any

                                      -42-



successor thereto), and (ii) all reports, proxy statements, financial statements
and other information distributed by the Borrower to its stockholders or
bondholders.

          (f) Further Information. The Borrower will promptly furnish to the
Agent, with a copy for each Lender, such other information and in such form as
the Agent or any Lender may reasonably request from time to time.

          (g) Notice of Certain Events. Promptly upon becoming aware of any of
the following, the Borrower shall give the Agent notice thereof, together with a
written statement of a Responsible Officer of the Borrower setting forth the
details thereof and any action with respect thereto taken or proposed to be
taken by the Borrower:

                  (i) Any Event of Default or Potential Default.

                  (ii) Any material correspondence with the PBGC, the Secretary
         of Labor or any representative of the IRS with respect to any Benefit
         Plan or Pension Plan, relating to an actual or threatened change or
         development which would have a Material Adverse Effect; and copies of
         any notices from the PBGC to the Borrower with respect to the intent of
         the PBGC to institute involuntary proceedings.

                  (iii) Any Environmental Claim pending or threatened against
         the Borrower or any Subsidiary of the Borrower, which Environmental
         Claim, if adversely resolved, individually or in the aggregate, could
         have a Material Adverse Effect; provided, however, that no such notice
         is required to be given with respect to any Environmental Claim if the
         Borrower reasonably determines that its liability, if any, with respect
         to such Environmental Claim will not exceed $1,000,000.

         (h) Visitation; Verification. The Borrower shall, and shall cause each
of its Subsidiaries to, permit the Lenders to make or cause to be made,
reasonable inspections of any of its books, records and papers and to make
extracts therefrom and copies thereof, or to make reasonable inspections and
examinations of any of its properties and facilities, and to discuss the
affairs, finances and accounts of the Borrower and its Subsidiaries with the
principal officers of the Borrower and with the Borrower's independent
accountants, all at all such reasonable times and as often as any Lender may
reasonably require, in order to assure that the Borrower and its Subsidiaries
are and will be in compliance with their respective obligations under the Loan
Documents or to evaluate the Lenders' investment in the then outstanding Notes.


                                      -43-



          The Agent shall promptly deliver to each Lender copies of all notices,
financial statements and other information received pursuant to this Section
5.01.

          5.02. Insurance. The Borrower shall, and shall cause each of its
Subsidiaries to, maintain, at its expense, and keep in effect with responsible
insurance companies, such liability insurance for bodily injury and third party
property damage as is customary in the case of corporations engaged in the same
or similar business or having similar properties, similarly situated. The
Borrower shall, and shall cause each of its Subsidiaries to, keep and maintain,
at its expense, its real and personal property insured against loss or damage by
fire, theft, explosion, spoilage, and all other risks ordinarily insured against
by other owners or users of such properties in similar businesses in an amount
equal to the full replacement or cash value thereof, subject to deductible
amounts which the Borrower, in its reasonable judgment, deems prudent.

         5.03. Payment of Taxes and Other Potential Charges and Priority Claims.
Except for situations where the failure to pay or discharge would not have a
Material Adverse Effect, the Borrower shall, and shall cause each Subsidiary to,
pay or discharge

                  (a) on or prior to the date on which penalties are imposed by
         a taxing authority with respect thereto, all taxes, assessments and
         other governmental charges imposed upon it or any of its properties;

                  (b) on or prior to the date when due, all lawful claims of
         materialmen, mechanics, carriers, warehousemen, landlords and other
         like Persons which, if unpaid, might result in the creation of a Lien
         upon any such property; and

                  (c) on or prior to the date when due, all other lawful claims
         which, if unpaid, might result in the creation of a Lien upon any such
         property or which, if unpaid, might give rise to a claim entitled to
         priority over general creditors of the Borrower or such Subsidiary in a
         case under Title 11 (Bankruptcy) of the United States Code, as amended;

provided, that unless and until foreclosure, distraint, levy, sale or similar
proceedings shall have been commenced the Borrower or such Subsidiary need not
pay or discharge any such tax, assessment, charge or claim so long as (x) the
validity thereof is contested in good faith and by appropriate proceedings
diligently conducted, (y) such reserves or other appropriate provisions as are
required by GAAP shall have been made therefor, and (z) such failure will not
have a Material Adverse Effect.

         5.04. Preservation of Corporate Status. The Borrower shall, and shall
cause each of its Subsidiaries to, do, or cause

                                      -44-



to be done, all things necessary to preserve, renew and keep in full force and
effect its corporate existence, permits and franchises, and use its best efforts
to comply with all Laws (including without limitation environmental Laws)
applicable to it except where such noncompliance could not have Material Adverse
Effect; provided, however, that nothing in this Section 5.04 shall prevent the
abandonment or termination of the Borrower's authorization to do business in any
foreign jurisdiction or of the corporate existence, rights and franchises of any
Subsidiary of the Borrower if such abandonment or termination is in the interest
of the Borrower and not disadvantageous in any material respect to the Lenders.

          5.05. Governmental Approvals and Filings. The Borrower shall, and
shall cause each Subsidiary to, keep and maintain in full force and effect all
Governmental Actions necessary, if any, in connection with execution and

surviving entity shall not, immediately after such merger or consolidation, be
in default of any of the Borrower's obligations under this Agreement or the
Notes, (iii) the continuing or surviving entity shall be a corporation organized
under the laws of the United States of America or any state thereof, (iv) after
giving effect to such consolidation or merger no Potential Default or Event of
Default would then exist and (v) such consolidation or merger shall not have a
Material Adverse Effect.

         6.06. ERISA Obligations. Except for matters which are not likely to

         provided to such Pension Plan under Section 401(a)(29) of the Code; or

                  (g) permit any Pension Plan to be terminated other than in a

of by the Borrower and its Subsidiaries in the then current fiscal year of the
Borrower would exceed an amount equal to 10% of the book value (computed in
accordance with GAAP) of all properties and assets of the Borrower and its
consolidated Subsidiaries at the end of the preceding fiscal year.

          6.09. Transactions with Affiliates. Neither the Borrower nor any
Subsidiary shall enter into any transaction (except transactions which do not in
any one calendar year involve in the aggregate an amount in excess of $500,000),

substantial part of its or his property; shall dissolve, wind-up, revoke or

substantial part of its property; or shall take any action in furtherance of any

         7.02. Consequences of an Event of Default.

         (a) If an Event of Default specified in subsections (a) through (i) of
Section 7.01 hereof shall occur and be continuing or shall exist, then, in
addition to all other rights and remedies which the Agent or any Lender may have
hereunder or under any other Loan Document, at law, in equity or otherwise, the
Lenders shall be under no further obligation to make Loans hereunder, and the
Agent may, and upon the written request of the Required Lenders shall, by notice
to the Borrower, from time to time do any or all of the following:

                                      -54-



                  (i) Declare the Commitments terminated, whereupon the
         Commitments will terminate and any fees hereunder shall be immediately
         due and payable without presentment, demand, protest or further notice
         of any kind, all of which are hereby waived, and an action therefor
         shall immediately accrue.

                  (ii) Declare the unpaid principal amount of the Loans,
         interest accrued thereon and all other Obligations to be immediately
         due and payable without presentment, demand, protest or further notice
         of any kind, all of which are hereby waived, and an action therefor
         shall immediately accrue.

          (b) If an Event of Default specified in subsection (j) or (k) of
Section 7.01 hereof shall occur or exist, then, in addition to all other rights
and remedies which the Agent or any Lender may have hereunder or under any other
Loan Document, at law, in equity or otherwise, the Commitments shall
automatically terminate and the Lenders shall be under no further obligation to
make Loans, and the unpaid principal amount of the Loans, interest accrued
thereon and all other Obligations shall become immediately due and payable
without presentment, demand, protest or notice of any kind, all of which are
hereby waived, and an action therefor shall immediately accrue.

         7.03. Application of Proceeds. After the occurrence of an Event of
Default and acceleration of the Loans, any payments received by any Lender on
account of Obligations shall be applied by the Agent to payment of the
Obligations in the following order:

                  First, to payment of that portion of the Obligations
         constituting accrued and unpaid interest on Loans, accrued and unpaid
         Revolving Credit Commitment Fees, ratably among the Lenders in
         proportion to the respective amounts described in this clause "First"
         due to them;

                  Second, to payment of that portion of the Obligations
         constituting unpaid principal of the Loans, ratably among the Lenders
         in proportion to the respective amounts described in this clause
         "Second" due to them;

                  Third, to payment of all other Obligations, ratably among the
         Lenders in proportion to the respective amounts described in this
         clause "Third" due to them; and

                  Fourth, to payment of that portion of the Obligations
         constituting fees, indemnities and other amounts due to the Agent in
         its capacity as such;

                                      -55-



                  Finally, the balance, if any, after all of the Obligations
         have been satisfied and all Commitments shall have terminated, to the
         Borrower or as otherwise required by law.

                                  ARTICLE VIII
                                    THE AGENT

          8.01. Appointment. Each Lender hereby irrevocably appoints Mellon
Bank, N.A. to act as Agent for such Lender under this Agreement and the other
Loan Documents. Each Lender hereby irrevocably authorizes the Agent to take such
action on behalf of such Lender under the provisions of this Agreement and the
other Loan Documents, and to exercise such powers and to perform such duties, as
are expressly delegated to or required of the Agent by the terms hereof or
thereof, together with such powers as are reasonably incidental thereto. Mellon
Bank, N.A. hereby agrees to act as Agent on behalf of the Lenders on the terms
and conditions set forth in this Agreement and the other Loan Documents, subject
to its right to resign as provided in Section 8.10 hereof. Each Lender hereby
irrevocably authorizes the Agent to execute and deliver each of the Loan
Documents and to accept delivery of such of the other Loan Documents as may not
require execution by the Agent. Each Lender agrees that the rights and remedies
granted to the Agent under the Loan Documents shall be exercised exclusively by
the Agent, and that no Lender shall have any right individually to exercise any
such right or remedy, except to the extent expressly provided herein or therein.

         8.02. General Nature of Agent's Duties. Notwithstanding anything to the
contrary elsewhere in this Agreement or in any other Loan Document:

                  (a) The Agent shall not have any duties or responsibilities
         except those expressly set forth in this Agreement and the other Loan
         Documents, and no implied duties or responsibilities on the part of the
         Agent shall be read into this Agreement or any Loan Document or shall
         otherwise exist.

                  (b) The duties and responsibilities of the Agent under this
         Agreement and the other Loan Documents shall be mechanical and
         administrative in nature, and the Agent shall not have a fiduciary
         relationship in respect of any Lender.

                  (c) The Agent is and shall be solely the agent of the Lenders.
         The Agent assumes no, and shall not at any time be deemed to have, any
         relationship of agency or trust with or any other duty or
         responsibility to, the Borrower, and Subsidiary of the Borrower or any
         other Person (except only for (i) its relationship as agent for, and
         its express duties



                                      -56-



         and responsibilities to, the Lenders and (ii) its express duties and
         responsibilities to, the Borrower, all as provided in this Agreement
         and the other Loan Documents).

                  (d) The Agent shall not be under any obligation to take any
         action hereunder or under any other Loan Document if the Agent believes
         in good faith after consultation with counsel that taking such action
         may conflict with any Law or any provision of this Agreement or any
         other Loan Document, or may require the Agent to qualify to do business
         in any jurisdiction where it is not then so qualified.

          8.03. Exercise of Powers. The Agent shall take any action of the type
specified in this Agreement or any other Loan Document as being within the
Agent's rights, powers or discretion in accordance with directions from the
Required Lenders (or, to the extent this Agreement or such Loan Document
expressly requires the direction or consent of some other Person or set of
Persons, then instead in accordance with the directions of such other Person or
set of Persons). In the absence of such directions, the Agent shall have the
authority (but under no circumstances shall be obligated), in its sole
discretion, to take any such action, except to the extent this Agreement or such
Loan Document expressly requires the direction or consent of the Required
Lenders (or some other Person or set of Persons), in which case the Agent shall
not take such action absent such direction or consent. Any action or inaction
pursuant to such direction, discretion or consent shall be binding on all the
Lenders. The Agent shall not have any liability to any Person as a result of (x)
the Agent acting or refraining from acting in accordance with the directions of
the Required Lenders (or other applicable Person or set of Persons), (y) unless
expressly required to act under the terms hereof, the Agent refraining from
acting in the absence of instructions to act from the Required Lenders (or other
applicable Person or set of Persons), whether or not the Agent has discretionary
power to take such action, or (z) the Agent taking discretionary action it is
authorized to take under this Section absent gross negligence or willful
misconduct.

          8.04. General Exculpatory Provisions. Notwithstanding anything to 
the contrary elsewhere in this Agreement or any other Loan Document:

                  (a) The Agent shall not be liable for any action taken or
         omitted to be taken by it under or in connection with this Agreement or
         anY other Loan Document, unless caused by its own gross negligence or
         willful misconduct.

                  (b) Except for the records to be maintained by the Agent
         pursuant to Section 9.02, the Agent shall not be responsible for (i)
         the execution, delivery, effectiveness, enforceability, genuineness,
         validity or adequacy of this Agreement or any other Loan Document, (ii)
         any recital,


                                      -57-


         representation, warranty, document, certificate, report or statement
         in, provided for in, or received under or in connection with, this
         Agreement or any other Loan Document or (iii) any failure of the
         Borrower or any Subsidiary of the Borrower or Lender to perform any of
         their respective obligations under this Agreement or any other Loan
         Document.

                  (c) Except as otherwise expressly provided herein, the Agent
         shall not be under any obligation to ascertain, inquire or give any
         notice relating to (i) the performance or observance of any of the
         terms or conditions of this Agreement or any other Loan Document on the
         part of the Borrower or any Subsidiary of the Borrower, (ii) the
         business, operations, condition (financial or otherwise) or prospects
         of the Borrower or any other Person, or (iii) except to the extent set
         forth in Section 8.05(f) hereof, the existence of any Event of 
         Default or Potential Default.

                  (d) The Agent shall not be under any obligation, either
         initially or on a continuing basis, to provide any Lender with any
         notices, reports or information of any nature, whether in its
         possession presently or hereafter, except for such notices, reports and
         other information expressly required by this Agreement or any other
         Loan Document to be furnished by the Agent to such Lender.

                  8.05. Administration by the Agent.

          (a) The Agent may rely in good faith upon any notice or other
communication of any nature (written or oral, including but not limited to
telephone conversations, whether or not such notice or other communication is
made in a manner permitted or required by this Agreement or any Loan Document)
purportedly made by or on behalf of the proper party or parties, and Agent shall
not have any duty to verify the identity or authority of any Person giving such
notice or other communication.

          (b) The Agent may consult with legal counsel (including, without
limitation, in-house counsel for the Agent or in-house or other counsel for the
Borrower), independent public accountants and any other experts selected by it
from time to time, and the Agent shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts.

         (c) The Agent may conclusively rely upon the truth of the statements
and the correctness of the opinions expressed in any certificates or opinions
furnished to the Agent in accordance with the requirements of this Agreement or
any other Loan Document. Whenever the Agent shall deem it necessary or desirable
that a matter be proved or established with respect to the Borrower or any
Lender, such matter may be established by a


                                      -58-



certificate of the Borrower or Lender, as the case may be, and the Agent may
conclusively rely upon such certificate (unless other evidence with respect to
such matter is specifically prescribed in this Agreement or another Loan
Document).

          (d) The Agent may fail or refuse to take any action unless it shall be
indemnified to its reasonable satisfaction from time to time against any and all
amounts, liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature which
may be imposed on, incurred by or asserted against the Agent by reason of taking
or continuing to take any such action.

          (e) The Agent may perform any of its duties under this Agreement or
any other Loan Document by or through agents or attorneys-in-fact. The Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

          (f) The Agent shall not be deemed to have any knowledge or notice of
the occurrence of any Event of Default or Potential Default unless the Agent has
actual knowledge or has received notice from a Lender or the Borrower referring
to this Agreement, describing such Event of Default or Potential Default, and
stating that such notice is a "notice of default." If the Agent receives such a
notice, the Agent shall give prompt notice thereof to each Lender.

         8.06. Lender Not Relying on Agent or Other Lenders. Each Lender
acknowledges as follows: (a) Neither the Agent nor any other Lender has made any
representations or warranties to it, and no act taken hereafter by the Agent or
any other Lender shall be deemed to constitute any representation or warranty by
the Agent or such other Lender to it. (b) It has, independently and without
reliance upon the Agent or any other Lender, and based upon such documents and
information as it has deemed appropriate, made its own credit and legal analysis
and decision to enter into this Agreement and the other Loan Documents. (c) It
will, independently and without reliance upon the Agent or any other Lender, and
based upon such documents and information as it shall deem appropriate at the
time, make its own decisions to take or not take action under or in connection
with this Agreement and the other Loan Documents.

         8.07. Indemnification. Each Lender agrees to reimburse and indemnify
the Agent and its directors, officers, employees and agents (to the extent not
reimbursed by the Borrower and without limitation of the obligations of the
Borrower to do so), Pro Rata, from and against any and all amounts, losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements of any kind or nature (including,
without limitation, the reasonable fees and disbursements of counsel for the
Agent or such other Person in connection with any

                                      -59-



investigative, administrative or judicial proceeding commenced or threatened,
whether or not the Agent or such other Person shall be designated a party
thereto) that may at any time be imposed on, incurred by or asserted against the
Agent or such other Person as a result of, or arising out of, or in any way
related to or by reason of, this Agreement, any other Loan Document, any
transaction from time to time contemplated hereby or thereby, or any transaction
financed in whole or in part or directly or indirectly with the proceeds of any
Loan, provided that no Lender shall be liable for any portion of such amounts,
losses, liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements resulting from the gross negligence or
willful misconduct of the Agent or such other Person, as finally determined by a
court of competent jurisdiction.

          8.08. Agent in its Individual Capacity. With respect to its
Commitments and the Obligations owing to it, the Agent shall have the same
rights and powers under this Agreement and each other Loan Document as any other
Lender and may exercise the same as though it were not the Agent, and the terms
"Lenders," "holders of Notes" and like terms shall include the Agent in its
individual capacity as such. The Agent and its affiliates may, without liability
to account, make loans to, accept deposits from, acquire debt or equity
interests in, act as trustee under indentures of, and engage in any other
business with, the Borrower and any stockholder, Subsidiary or Affiliate of the
Borrower, as though the Agent were not the Agent hereunder.

         8.09. Holders of Notes. The Agent may deem and treat the Lender which
is payee of a Note as the owner and holder of such Note for all purposes hereof
unless and until a Transfer Supplement with respect to the assignment or
transfer thereof shall have been filed with the Agent in accordance with Section
9.14 hereof. Any authority, direction or consent of any Person who at the time
of giving such authority, direction or consent is shown in the Register as being
a Lender shall be conclusive and binding on each present and subsequent holder,
transferee or assignee of any Note or Notes payable to such Lender or of any
Note or Notes issued in exchange therefor.


          8.10. Successor Agents. The Agent may resign at any time by giving 30
days' written notice thereof to the Lenders and the Borrower. The Agent may be
removed by the Required Lenders upon 30 days' written notice thereof to the
Agent, the Lenders and the Borrower. Upon receipt of notice of any such
resignation or removal, the Borrower shall have the right to appoint a successor
Agent; provided, that the Required Lenders shall have the right to disapprove
such successor Agent. If no successor Agent shall have been so appointed and
consented to, and shall have accepted such appointment, within 20 days after
such notice of resignation or removal, then the Required Lenders shall appoint a
successor Agent to succeed to the obligations of the Agent hereunder. Each


                                      -60-



successor Agent shall be a commercial bank or trust company organized under the
laws of the United States of America or any State thereof. Upon the acceptance
by a successor Agent of its appointment as Agent hereunder, such successor Agent
shall thereupon succeed to and become vested with all the properties, rights,
powers, privileges and duties of the former Agent, without further act, deed or
conveyance. Upon the effective date of resignation or removal of a retiring
Agent, such Agent shall be discharged from its duties under this Agreement and
the other Loan Documents, but the provisions of this Agreement shall inure to
its benefit as to any actions taken or omitted by it while it was Agent under
this Agreement. If and so long as no successor Agent shall have been appointed,
then any notice or other communication required or permitted to be given by the
Agent shall be sufficiently given if given by the Required Lenders, all notices
or other communications required or permitted to be given to the Agent shall be
given to each Lender, and all payments to be made to the Agent shall be made
directly to the Borrower or Lender for whose account such payment is made.

          8.11. Calculations. The Agent shall not be liable for any calculation,
apportionment or distribution of payments made by it in good faith except for
gross negligence. If such calculation, apportionment or distribution is
subsequently determined to have been made in error, the sole recourse of any
Lender to whom payment was due but not made shall be to recover from the other
Lenders any payment in excess of the amount to which they are determined to be
entitled or, if the amount due was not paid by the Borrower, to recover such
amount from the Borrower.

         8.12. Funding by Agent. Unless the Agent shall have been notified in
writing by any Lender not later than the close of business on the day before the
day on which Loans are requested by the Borrower to be made that such Lender
will not make its ratable share of such Loans, the Agent may assume that such
Lender will make its ratable share of the Loans, and in reliance upon such
assumption the Agent may (but in no circumstances shall be required to) make
available to the Borrower a corresponding amount. If and to the extent that any
Lender fails to make such payment to the Agent on such date, such Lender shall
pay such amount on demand (or, if such Lender fails to pay such amount on
demand, the Borrower shall pay such amount on demand), together with interest,
for the Agent's own account, for each day from and including the date of the
Agent's payment to and including the date of repayment to the Agent (before and
after judgment) at the Federal Funds Effective Rate for the first day and
thereafter at the rate or rates per annum applicable to such Loans. All payments
to the Agent under this Section shall be made to the Agent at its Office in
Dollars in funds immediately available at such Office, without set-off,
withholding, counterclaim or other deduction of any nature.



                                      -61-



                                   ARTICLE IX
                                 MISCELLANEOUS

         9.01. Holidays. Whenever any payment or action to be made or taken
hereunder or under any other Loan Document 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 be included in
computing interest or fees, if any, in connection with such payment or action.

         9.02. Records. The unpaid principal amount of the Loans owing to each
Lender, the unpaid interest accrued thereon, the interest rate or rates
applicable to such unpaid principal amount, the duration of such applicability,
each Lender's Committed Amount and the accrued and unpaid Commitment Fees shall
at all times be ascertained from the records of the Agent, which shall be
conclusive absent manifest error.

         9.03. Amendments and Waivers. Neither this Agreement nor any Loan
Document may be amended, modified or supplemented except in accordance with the
provisions of this Section. The Required Lenders and the Borrower may from time
to time amend, modify or supplement the provisions of this Agreement or any
other Loan Document for the purpose of amending, adding to, or waiving any
provisions or changing in any manner the rights and duties of the Borrower, the
Agent or any Lender. Any such amendment, modification or supplement made by the
Borrower, the Agent and the Required Lenders in accordance with the provisions
of this Section shall be in writing and shall be binding upon the Borrower, each
Lender and the Agent; provided, that no such amendment, modification or
supplement may be made which will:

                  (a) Increase the Committed Amount of any Lender over the
         amount thereof then in effect, subject any Lender to additional
         obligations hereunder or extend the Revolving Credit Maturity Date
         without the written consent of each Lender affected thereby;

                  (b) Reduce the principal amount of or extend the time for any
         payment of any Loan, or reduce the amount of or rate of interest or
         extend the time for payment of interest borne by any Loan or extend the
         time for payment of or reduce the amount of any Commitment Fee or
         reduce or postpone the date for payment of any other fees, expenses,
         indemnities or amounts payable under any Loan Document, without the
         written consent of each Lender affected thereby;

                  (c) Change the definition of "Required Lenders" or amend this
         Section 9.03, without the written consent of all the Lenders;



                                      -62-



                  (d) Amend or waive any of the provisions of Article IX hereof,
         or impose additional duties upon the Agent or otherwise adversely
         affect the rights, interests or obligations of the Agent, without the
         written consent of the Agent; or

                  (e) Amend Section 2.13 hereof, without the written consent of
         all Lenders.

provided further, that Transfer Supplements may be entered into in the manner
provided in Section 9.14 hereof. Any such amendment, modification or supplement
must be in writing and shall be effective only to the extent set forth in such
writing. Any Event of Default or Potential Default waived or consented to in any
such amendment, modification or supplement shall be deemed to be cured and not
continuing to the extent and for the period set forth in such waiver or consent,
but no such waiver or consent shall extend to any other or subsequent Event of
Default or Potential Default or impair any right consequent thereto.

         9.04. No Implied Waiver; Cumulative Remedies. No course of dealing and
no delay or failure of the Agent or any Lender in exercising any right, power or
privilege under this Agreement or any other Loan Document shall affect any other
or future exercise thereof or exercise of any other right, power or privilege;
nor shall any single or partial exercise of any such right, power or privilege
or any abandonment or discontinuance of steps to enforce such a right, power or
privilege preclude any further exercise thereof or of any other right, power or
privilege. The rights and remedies of the Agent and the Lenders under this
Agreement and any other Loan Document are cumulative and not exclusive of any
rights or remedies which the Agent or any Lender would otherwise have hereunder
or thereunder, at law, in equity or otherwise.

         9.05. Notices.

          (a) Except to the extent otherwise expressly permitted hereunder or
thereunder, all notices, requests, demands, directions and other communications

be sent by first-class mail, or by nationally-recognized overnight courier, or

by such an overnight courier), or by personal delivery. All notices shall be

Days after deposit in the mail.

          (b) Any Lender giving any notice to the Borrower shall simultaneously
send a copy thereof to the Agent, and the Agent shall promptly notify the other
Lenders of the receipt by it of any such notice.

          (c) The Agent and each Lender may rely on any notice (whether or not
such notice is made in a manner permitted or required by this Agreement or any
Loan Document) purportedly made by or on behalf of the Borrower, and neither the
Agent nor any Lender shall have any duty to verify the identity or authority of
any Person giving such notice.

         9.06. Expenses; Taxes; Indemnity.

         (a) The Borrower agrees to pay or cause to be paid and to save the
Agent and each of the Lenders harmless against liability for the payment of all
reasonable out-of-pocket costs and expenses (including but not limited to
reasonable fees and expenses of counsel to the Agent, local counsel, auditors,
consulting engineers, appraisers, and all other professional, accounting,

negotiation, preparation, execution, delivery, administration and performance of
this Agreement and the other Loan Documents, (ii) any requested amendments,
modifications, supplements, waivers or consents (whether or not ultimately

related in any way to this Agreement or the Loan Documents).

similar impositions now or hereafter determined by the Agent or any Lender to be
payable in connection with this Agreement or any other Loan Documents or any
other documents, instruments or transactions pursuant to or in connection
herewith or therewith, and the Borrower agrees to save the Agent and each Lender
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 fees, taxes or impositions.

                                      -64-



         (c) The Borrower hereby agrees to reimburse and indemnify each of the
Indemnified Parties from and against any and all losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements of any kind or nature whatsoever (including, without limitation,
the reasonable fees and disbursements of counsel for such Indemnified Party in
connection with any investigative, administrative or judicial proceeding
commenced or threatened, whether or not such Indemnified Party shall be
designated a party thereto) that may at any time be imposed on, asserted against
or incurred by such Indemnified Party as a result of, or arising out of, or in
any way related to or by reason of, any transaction financed in whole or in part
or directly or indirectly with the proceeds of any Loan (and without in any way
limiting the generality of the foregoing, including any violation or breach of
any Requirement of Law or any other Law by the Borrower or any Subsidiary); or
any exercise by the Agent or any Lender of any of its rights or remedies under
this Agreement or any other Loan Document; but excluding any such losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements resulting solely from the gross
negligence or willful misconduct of such Indemnified Party. If and to the extent
that the foregoing obligations of the Borrower under this subsection (c), or any
other indemnification obligation of the Borrower hereunder or under any other
Loan Document, are unenforceable for any reason, the Borrower hereby agrees to
make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable Law.

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

         9.08. Prior Understandings. This Agreement and the other Loan Documents
supersede all prior and contemporaneous understandings and agreements, whether
written or oral, among the parties hereto relating to the transactions provided
for herein and therein.

         9.09. Duration; Survival. All representations and warranties of the
Borrower contained herein or in any other Loan Document or made in connection
herewith shall survive the making of, and shall not be waived by the execution
and delivery, of this Agreement or any other Loan Document, any investigation by
or knowledge of the Agent or any Lender, the making of any Loan, or any other
event or condition whatever. All covenants and agreements of the Borrower
contained herein or in any other Loan Document shall continue in full force and
effect from and after

                                      -65-



the date hereof so long as any Borrower may borrow hereunder and until payment
in full of all Obligations. Without limitation, all obligations of the Borrower
hereunder or under any other Loan Document to make payments to or indemnify the
Agent or any Lender shall survive the payment in full of all other Obligations,
termination of the Borrower's right to borrow hereunder, and all other events
and conditions whatever. In addition, all obligations of each Lender to make
payments to or indemnify the Agent or the other Lenders shall survive the
payment in full by the Borrower of all Obligations, termination of the
Borrower's right to borrow hereunder, and all other events or conditions
whatever.

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

         9.11. Limitation on Payments. The parties hereto intend to conform to
all applicable Laws in effect from time to time limiting the maximum rate of
interest that may be charged or collected. Accordingly, notwithstanding any
other provision hereof or of any other Loan Document, the Borrower shall not be
required to make any payment to or for the account of any Lender, and each
Lender shall refund any payment made by the Borrower, to the extent that such
requirement or such failure to refund would violate or conflict with nonwaivable
provisions of applicable Laws limiting the maximum amount of interest which may
be charged or collected by such Lender.

         9.12. Set-Off. The Borrower hereby agrees that, to the fullest extent
permitted by law, if any Obligation of the Borrower shall be due and payable (by
acceleration or otherwise), each Lender shall have the right, without notice to
the Borrower, to set-off against and to appropriate and apply to the Obligation
any indebtedness, liability or obligation of any nature owing to the Borrower by
such Lender, including but not limited to all deposits (whether time or demand,
general or special, provisionally credited or finally credited, whether or not
evidenced by a certificate of deposit) now or hereafter maintained by the
Borrower with such Lender. Such right shall be absolute and unconditional in all
circumstances and, without limitation, shall exist whether or not such Lender or
any other Person shall have given notice or made any demand to the Borrower or
any other Person, whether such indebtedness, obligation or liability owed to the
Borrower is contingent, absolute, matured or unmatured (it being agreed that
such Lender may deem such indebtedness, obligation or liability to be then due
and payable at the time of such setoff), and regardless of the existence or
adequacy of any collateral, guaranty or any other security, right or remedy
available to any Lender or any other Person. The Borrower hereby agrees that, to
the fullest extent permitted by law, any Participant and any branch, subsidiary
or affiliate of any Lender

                                      -66-



or any Participant shall have the same rights of set-off as a Lender as provided
in this Section (regardless of whether such Participant, branch, subsidiary or
affiliate would otherwise be deemed in privity with or a direct creditor of such
Borrower). The rights provided by this Section are in addition to all other
rights of set-off and banker's lien and all other rights and remedies which any
Lender (or any such Participant, branch, subsidiary or affiliate) may otherwise
have under this Agreement, any other Loan Document, at law or in equity, or
otherwise, and nothing in this Agreement or any Loan Document shall be deemed a
waiver or prohibition of or restriction on the rights of set-off or bankers'
lien of any such Person.

         9.13. Sharinq of Collections. The Lenders hereby agree among themselves
that if any Lender shall receive (by voluntary payment, realization upon
security, set-off or from any other source) any amount on account of the Loans,
interest thereon, or any other Obligation contemplated by this Agreement or the
other Loan Documents to be made by the Borrower pro rata to all Lenders in
greater proportion than any such amount received by any other Lender, then the
Lender receiving such proportionately greater payment shall notify each other
Lender and the Agent of such receipt, and equitable adjustment will be made in
the manner stated in this Section so that, in effect, all such excess amounts
will be shared ratably among all of the Lenders. The Lender receiving such
excess amount shall purchase (which it shall be deemed to have done
simultaneously upon the receipt of such excess amount) for cash from the other
Lenders a participation in the applicable Obligations owed to such other Lenders
in such amount as shall result in a ratable sharing by all Lenders of such
excess amount (and to such extent the receiving Lender shall be a Participant).
If all or any portion of such excess amount is thereafter recovered from the
Lender making such purchase, such purchase shall be rescinded and the purchase
price restored to the extent of such recovery, together with interest or other
amounts, if any, required by Law to be paid by the Lender making such purchase.
The Borrower hereby consents to and confirms the foregoing arrangements. Each
Participant shall be bound by this Section as fully as if it were a Lender
hereunder.

         9.14. Successors and Assigns; Participations; Assignments.

         (a) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the Borrower, the Lenders, all future holders of the
Notes, the Agent and their respective successors and assigns, except that the
Borrower may not assign or transfer any of its rights hereunder or interests
herein without the prior written consent of all the Lenders and the Agent, and
any purported assignment without such consent shall be void.

                                      -67-


          (b) Participations. Any Lender may, in the ordinary course of its
commercial banking business and in accordance with applicable Law, at any time
sell participations to one or more commercial banks or other Persons (each a
"Participant") in all or a portion of its rights and obligations under this
Agreement and the other Loan Documents (including, without limitation, all or a
portion of its Commitments and the Loans owing to it and any Note held by it);
provided, that

                  (i) any such Lender's obligations under this Agreement and the
         other Loan Documents shall remain unchanged,

                  (ii) such Lender shall remain solely responsible to the other
         parties hereto for the performance of such obligations,

                  (iii) the parties hereto shall continue to deal solely and
         directly with such Lender in connection with such Lender's rights and
         obligations under this Agreement and each of the other Loan Documents,

                  (iv) such Participant shall be bound by the provisions of
         Section 9.13 hereof, and the Lender selling such participation shall
         obtain from such Participant a written confirmation of its agreement to
         be so bound,

                  (v) no Participant (unless such Participant is an affiliate of
         such Lender, or is itself a Lender) shall be entitled to require such
         Lender to take or refrain from taking action under this Agreement or
         under any other Loan Document, except that such Lender may agree with
         such Participant that such Lender will not, without such Participant's
         consent, take action of the type described in subsections (a), (b),
         (c), (d) or (e) of Section 9.03 hereof; notwithstanding the foregoing,
         in no event shall any participation by an Lender have the effect of
         releasing such Lenders from its obligations hereunder, and

                  (vi) no Participant shall be an Affiliate of the Borrower.

The Borrower agrees that any such Participant shall be entitled to the benefits
of Sections 2.12, 2.14 and 9.06 with respect to its participation in the
Commitments and the Loans outstanding from time to time but only to the extent
such Participant sustains such losses; provided, that no such Participant shall
be entitled to receive any greater amount pursuant to such Sections than the
transferor Lender would have been entitled to receive in respect of the amount
of the participation transferred to such Participant had no such transfer
occurred.

         (c) Assignments. Any Lender may, in the ordinary course of its
commercial banking business and in accordance with applicable Law, at any time
assign all or a portion of its rights

                                      -68-


and obligations under this Agreement and the other Loan Documents (including,
without limitation, all or any portion of its Commitments and Obligations owing
to it and any Note held by it) to any Lender, any affiliate of a Lender or to
one or more additional commercial banks or other Persons (each a "Purchasing
Lender"); provided, that

                  (i) any such assignment to a Purchasing Lender which is not a
         Lender shall be made only with the consent of the Borrower and the
         Agent which shall not be unreasonably withheld,

                  (ii) if a Lender makes such an assignment of less than all of
         its then remaining rights and obligations under this Agreement and the
         other Loan Documents, such transferor Lender shall retain, after such
         assignment, a minimum principal amount of $5,000,000 of the Commitments
         and Revolving Credit Loans then outstanding, and such assignment shall
         be in a minimum aggregate principal amount of $5,000,000 of the
         Commitments and Revolving Credit Loans then outstanding,

                  (iii) each such assignment shall be of a constant, and not a
         varying, percentage of each Commitment of the transferor Lender and of
         all of the transferor Lender's rights and obligations under this
         Agreement and the other Loan Documents, and

                  (iv) each such assignment shall be made pursuant to a Transfer
         Supplement in substantially the form of Exhibit C to this Agreement,
         duly completed (a "Transfer Supplement").

In order to effect any such assignment, the transferor Lender and the Purchasing
Lender shall execute and deliver to the Agent a duly completed Transfer
Supplement (including the consents required by clause (i) of the preceding
sentence) with respect to such assignment, together with any Note or Notes
subject to such assignment (the "Transferor Lender Notes") and a processing and
recording fee of $2,500; and, upon receipt thereof, the Agent shall accept such
Transfer Supplement. Upon receipt of the Purchase Price Receipt Notice pursuant
to such Transfer Supplement, the Agent shall record such acceptance in the
Register. Upon such execution, delivery, acceptance and recording, from and
after the Transfer Effective Date specified in such Transfer Supplement

                  (x) the Purchasing Lender shall be a party hereto and, to the
         extent provided in such Transfer Supplement, shall have the rights and
         obligations of a Lender hereunder, and

                  (y) the transferor Lender thereunder shall be released from
         its obligations under this Agreement to the extent so transferred (and,
         in the case of an Transfer Supplement

                                      -69-



         covering all or the remaining portion of a transferor Lender's rights
         and obligations under this Agreement, such transferor Lender shall
         cease to be a party to this Agreement) from and after the Transfer
         Effective Date.

On or prior to the Transfer Effective Date specified in an Transfer Supplement,
the Borrower, at its expense, shall execute and deliver to the Agent (for
delivery to the Purchasing Lender) new Notes evidencing such Purchasing Lender's
assigned Commitments or Loans and (for delivery to the transferor Lender)
replacement Notes in the principal amount of the Loans or Commitments retained
by the transferor Lender (such Notes to be in exchange for, but not in payment
of, those Notes then held by such transferor Lender). Each such Note shall be
dated the date and be substantially in the form of the predecessor Note. The
Agent shall mark the predecessor Notes "exchanged" and deliver them to the
Borrower. Accrued interest and accrued fees shall be paid to the Purchasing
Lender at the same time or times provided in the predecessor Notes and this
Agreement.

          (d) Register. The Agent shall maintain at its office a copy of each
Transfer Supplement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Obligations owing to, each Lender from time to time. The
entries in the Register shall be conclusive absent manifest error and the
Borrower, the Agent and the Lenders may treat each person whose name is recorded
in the Register as a Lender hereunder for all purposes of the Agreement. The
Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

          (e) Financial and Other Information. The Borrower authorizes the Agent
and each Lender to disclose to any Participant or Purchasing Lender (each, a
"transferee") and any prospective transferee any and all financial and other
information in such Person's possession concerning the Borrower and its
Subsidiaries and Affiliates which has been or may be delivered to such Person by
or on behalf of the Borrower in connection with this Agreement or any other Loan
Document or such Person's credit evaluation of the Borrower and its Subsidiaries
and Affiliates.

                  9.15. Governing Law; Submission to Jurisdiction.

         (a) Governing Law. THIS AGREEMENT AND ALL OTHER LOAN DOCUMENTS (EXCEPT
TO THE EXTENT, IF ANY, OTHERWISE EXPRESSLY STATED IN SUCH OTHER LOAN DOCUMENTS)
SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK, WITHOUT REGARD TO CHOICE OF LAW PRINCIPLES.

         (b) Certain Waivers. THE BORROWER HEREBY IRREVOCABLY AND
UNCONDITIONALLY:

                                      -70-



         (i) AGREES THAT ANY ACTION, SUIT OR PROCEEDING BY ANY PERSON ARISING
FROM OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY STATEMENT,
COURSE OF CONDUCT, ACT, OMISSION, OR EVENT OCCURRING IN CONNECTION HEREWITH OR
THEREWITH (COLLECTIVELY, "RELATED LITIGATION") MAY BE BROUGHT IN ANY STATE OR
FEDERAL COURT OF COMPETENT JURISDICTION SITTING IN THE CITY AND COUNTY OF NEW
YORK, NEW YORK, AND SUBMITS TO THE JURISDICTION OF SUCH COURTS;

         (ii) WAIVES ANY OBJECTION WHICH IT MAY HAVE AT ANY TIME TO THE LAYING
OF VENUE OF ANY RELATED LITIGATION BROUGHT IN ANY SUCH COURT, WAIVES ANY CLAIM
THAT ANY SUCH RELATED LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, AND
WAIVES ANY RIGHT TO OBJECT, WITH RESPECT TO ANY RELATED LITIGATION BROUGHT IN
ANY SUCH COURT, THAT SUCH COURT DOES NOT HAVE JURISDICTION OVER THE BORROWER;
AND

         (iii) CONSENTS AND AGREES TO SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER
LEGAL PROCESS IN ANY RELATED LITIGATION BY REGISTERED OR CERTIFIED U.S. MAIL,
POSTAGE PREPAID, TO THE BORROWER AT THE ADDRESS FOR NOTICES DESCRIBED IN SECTION
9.05 HEREOF, AND CONSENTS AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE IN EVERY
RESPECT VALID AND EFFECTIVE SERVICE (BUT NOTHING HEREIN SHALL AFFECT THE
VALIDITY OR EFFECTIVENESS OF PROCESS SERVED IN ANY OTHER MANNER PERMITTED BY
LAW).

         9.16. Replacement of Lender. If (a) a change in control shall have
occurred with respect to any Lender or (b) any Lender shall impose increased
costs on the Borrower pursuant to Section 2.12(a) or 2.12(c) hereof, the
Borrower may, upon not less than 30 Business Days' notice to the Agent, cause a
Replacement Lender reasonably satisfactory to the Agent (which may be one of the
other Lenders) to purchase all of such Lender's interests in accordance with the
provisions of Section 9.14(c) hereof.


                                      -71-


         IN WITNESS WHEREOF, the parties hereto, by their officers thereunto
duly authorized, have executed and delivered this Agreement as of the date first
above written.

                               TRANSFER SUPPLEMENT


         THIS TRANSFER SUPPLEMENT, dated as of the date specified in Item 1 of
Schedule I hereto, among the Transferor Lender specified in Item 2 of Schedule I
hereto (the "Transferor Lender"), each Purchasing Lender specified in Item 3 of
Schedule I hereto (each a "Purchasing Lender") and Mellon Bank, N.A., as Agent
for the Lenders under the Revolving Credit Agreement described below.

                                    Recitals:

         A. This Transfer Supplement is being executed and delivered in
accordance with Section 9.14(c) of the Revolving Credit Agreement, dated as of
December 1, 1991 by and among Barnes Group Inc., a Delaware corporation (the
"Borrower"), the Lenders parties thereto, and Mellon Bank, N.A., a national
banking association, as Agent (as the same may be amended, modified or
supplemented from time to time, the "Credit Agreement"). Capitalized terms used
herein without definition have the meaning specified in the Credit Agreement.

         B. Each Purchasing Lender (if it is not already a Lender) wishes to
become a Lender party to the Credit Agreement.

         C. The Transferor Lender is selling and assigning to each Purchasing
Lender, and each Purchasing Lender is purchasing and assuming, a certain portion
of the Transferor Lender's rights and obligations under the Credit Agreement,
including, without limitation, the Transferor Lender's Commitments and Loans
owing to it and any Notes held by it (the "Transferor Lender's Interests").

         NOW, THEREFORE, the parties hereto, intending to be legally bound,
hereby agree as follows:

         1. Transfer Effective Notice. Upon receipt by the Agent of five
counterparts of this Transfer Supplement (to each of which is attached a fully
completed Schedule I and Schedule II), and each of which has been executed by
the Transferor Lender, by each Purchasing Lender and by any other Person
required by Section 9.14(c) of the Credit Agreement to execute this Transfer
Supplement, the Agent will transmit to the Borrower, the Transferor Lender and
each Purchasing Lender a transfer effective notice, substantially in the form of
Schedule III to this Transfer Supplement (a "Transfer Effective Notice"). The
date specified in such Transfer Effective Notice as the date on which the
transfer effected by this Transfer Supplement shall become effective (the
"Transfer Effective Date") shall be the fifth Business Day following the date of
such Transfer Effective Notice or such other date as shall be agreed upon among
the Transfer Lender, the Purchasing Lender, the Agent and the Borrower. From and
after the Transfer Effective Date each Purchasing Lender (if not already a







Lender party to the Credit Agreement) shall be a Lender party to the Credit
Agreement for all purposes thereof having the respective interests in the
Transferor Lender's interests reflected in this Transfer Supplement.

         2. Purchase Price; Sale. At or before 12:00 Noon, local time at the
Transferor Lender's office specified in Schedule III, on the Transfer Effective
Date, each Purchasing Lender shall pay to the Transferor Lender, in immediately
available funds, an amount equal to the purchase price, as agreed between the
Transferor Lender and such Purchasing Lender (the "Purchase Price"), of the
portion being purchased by such Purchasing Lender (such Purchasing Lender's
"Purchased Percentage") of the Transferor Lender's Interests. Effective upon
receipt by the Transferor Lender of the Purchase Price from a Purchasing Lender,
the Transferor Lender hereby irrevocably sells, assigns and transfers to such
Purchasing Lender, without recourse, representation or warranty (express or
implied) except as set forth in Section 6 hereof, and each Purchasing Lender
hereby irrevocably purchases, takes and assumes from the Transferor Lender such
Purchasing Lender's Purchased Percentage of the Transferor Lender's Interests.
The Transferor Lender shall promptly notify the Agent of the receipt of the
Purchase Price from a Purchasing Lender ("Purchase Price Receipt Notice"). Upon
receipt by the Agent of such Purchase Price Receipt Notice, the Agent shall
record in the Register the information with respect to such sale and purchase as
contemplated by Section 9.14(d) of the Credit Agreement.

         3. Principal, Interest and Fees. All principal payments, interest, fees
and other amounts that would otherwise be payable from and after the Transfer
Effective Date to or for the account of the Transferor Lender in respect of the
Transferor Lender's Interests shall, instead, be payable to or for the account
of the Transferor Lender and the Purchasing Lenders, as the case may be, in
accordance with their respective interests as reflected in this Transfer
Supplement.

         4. Closing Documents. Concurrently with the execution and delivery
hereof, the Transferor Lender will request that the Borrower provide to each
Purchasing Lender (if it is not already a Lender party to the Credit Agreement)
conformed copies of all documents delivered to such Transferor Lender on the
Closing Date in satisfaction of conditions precedent set forth in the Credit
Agreement.

         5. Further Assurances. Each of the parties to this Transfer Supplement
agrees that at any time and from time to time upon the written request of any
other party, it will execute and deliver such further documents and do such
further acts and things as such other party may reasonably request in order to
effect the purposes of this Transfer Supplement.

this Transfer Supplement, the Transferor Lender and each Purchasing Lender
confirm to and agree with each other and the Agent and the Lenders as follows:

                  (a) Other than the representation and warranty that it is the
         legal and beneficial owner of the interest being assigned hereby free
         and clear of any adverse claim, the Transferor Lender makes no
         representation or warranty and assumes no responsibility with respect
         to (i) the execution, delivery, effectiveness, enforceability,
         genuineness, validity or adequacy of the Credit Agreement or any other
         Loan Document, (ii) any recital, representation, warranty, document,
         certificate, report or statement in, provided for in, received under or
         in connection with, the Credit Agreement or any other Loan Document, or

         priority, adequacy or value, now or hereafter, of any Lien or other
         direct or indirect security afforded or purported to be afforded by any
         of the Loan Documents or otherwise from time to time.

                  (b) The Transferor Lender makes no representation or warranty
         and assumes no responsibility with respect to (i) the performance or
         observance of any of the terms or conditions of the Credit Agreement or
         any other Loan Document on the part of the Borrower or any other
         Borrower, (ii) the business, operations, condition (financial or
         otherwise) or prospects of the Borrower or any other Borrower or any
         other Person, or (iii) the existence of any Event of Default or
         Potential Default.

                  (c) Each Purchasing Lender confirms that it has received a
         copy of the Credit Agreement and each of the other Loan Documents,
         together with copies of the financial statements referred to in Section
         3.06 thereof, the most recent financial statements delivered pursuant
         to Section 5.01 thereof, if any, and such other documents and
         information as it has deemed appropriate to make its own credit and
         legal analysis and decision to enter into this Transfer Supplement.
         Each Purchasing Lender confirms that it has made such analysis and
         decision independently and without reliance upon the Agent, the
         Transferor Lender or any other Lender.

                  (d) Each Purchasing Lender, independently and without reliance
         upon the Agent, the Transferor Lender or any other Lender, and based on
         such documents and information as it shall deem appropriate at the
         time, will make its own decisions to take or not take action under or
         in connection with the Credit Agreement or any other Loan Document.



                                      -3-




                  (e) Each Purchasing Lender irrevocably appoints the Agent to
         act as Agent for such Purchasing Lender under the Agreement and the
         other Loan Documents, all in accordance with Article IX of the Credit
         Agreement and the other provisions of the Credit Agreement and the
         other Loan Documents.

                  (f) Each Purchasing Lender agrees that it will perform in
         accordance with their terms all of the obligations which by the terms
         of the Credit Agreement and the other Loan Documents are required to be
         performed by it as a Lender.

information with respect to each Purchasing Lender.

without regard to principles of choice of law.

         9. Counterparts. This Transfer Supplement may be executed on any number

counterparts shall constitute but one and the same instrument.

Gentlemen/Mesdames:

          I am Vice President, General Counsel and Secretary of Barnes Group
Inc., a Delaware corporation (the "Borrower"), and have acted as counsel to the
Borrower in connection with the Revolving Credit Agreement dated as of December
1, 1991 between you and the Borrower (the "Agreement"). This opinion is being
delivered to the Lenders pursuant to Section 4.01(d) of the Agreement.
Capitalized terms used herein without definition are used as defined in the
Agreement.

          In this connection, I have examined and am familiar with the originals
or copies, certified or otherwise identified to my satisfaction, of the
Agreement, the Revolving Credit Notes, the Restated Certificate of Incorporation
and By-Laws of the Company, as currently in effect, resolutions of the Company's
Board of Directors authorizing the Agreement and the issuance of the Notes, and
such other documents as I have deemed necessary or appropriate as a basis for
the opinions set forth below. In my examination, I have assumed the genuineness
of all signatures (except for signatures of officers of the Borrower), the legal
capacity of natural persons, the authenticity of all documents submitted to me
as originals, the conformity to original documents of all documents submitted to
me as certified or photostatic copies and the authenticity of the originals of
such copies. As to the facts material to this opinion which I did not
independently establish or verify, I have relied upon statements and
representations of officers and other representatives of the Borrower and
others.

          I am admitted to the bar in the State of Missouri and am not admitted
in any of the jurisdictions in which the Foreign Subsidiaries are incorporated.
With respect to Foreign Subsidiaries, I am generally familiar with their
organizational structure, have put in place

                                                                 .    .    .

procedures designed to ensure their continued qualification to do business and
good standing in their respective jurisdictions, and am generally familiar with
their current business activities and financial status.

         Based upon and subject to the forgoing, I am of the opinion that:

1.       The Borrower is a corporation duly organized, validly existing and in
         good standing under the laws of the State of Delaware, has the
         corporate power to own its property and to carry on its business as now
         conducted and is qualified to do business in every jurisdiction where
         such qualification is necessary and in which the failure to be so
         qualified would have a Material Adverse Effect.

2.       Each Subsidiary incorporated in the United States ("Domestic
         Subsidiary") is a corporation duly organized, validly existing and in
         good standing under the laws of its state of incorporation, has the
         corporate power to own its property and to carry on its business as now
         conducted and is qualified to do business in every jurisdiction where
         such qualification is necessary and in which the failure to be so
         qualified would have a Material Adverse Effect. The shares of stock of
         each Domestic Subsidiary purported to be owned by the Borrower are
         validly issued, fully paid and nonassessable and are owned by the
         Borrower free and clear of any mortgage, lien, pledge, charge, security
         interest or other encumbrance.

3.       To the best of my knowledge, without any special investigation by me,
         (a) each subsidiary not incorporated in the United States ("Foreign
         Subsidiary") is a corporation duly organized, validly existing and in
         good standing under the laws of the jurisdiction of its incorporation,
         has the corporate power to own its property and to carry on its
         business as now conducted and is qualified to do business in every
         jurisdiction where such qualification is necessary and in which the
         failure to be so qualified would have a Material Adverse Effect, and
         (b) the shares of stock of each Foreign Subsidiary purported to be
         owned by the Borrower or another Subsidiary are validly issued, fully
         paid and

                                                                 .   .    .

         nonassessable and are owned by the Borrower or another Subsidiary
         (except in the case of Director's qualifying shares) free and clear of
         any mortgage, lien, pledge, charge, security interest or other
         encumbrance.

4.       The Borrower has the corporate power to execute, deliver and perform
         the Agreement, to borrow under the Agreement, and to execute and
         deliver the Notes.

5.       As of the date hereof, the execution, delivery and performance of the
         Agreement, any borrowings under the Agreement and the execution and
         delivery of the Notes by the Borrower, (a) have been duly authorized by
         all requisite corporate action (including, without limitation, any
         requisite action of the stockholders of the Borrower), (b) will not
         violate any provision of the Restated Certificate of Incorporation or
         By-Laws of the Borrower or any Subsidiary and (c) will not be in
         conflict with, result in a breach of or constitute (with due notice or
         lapse of time or both) a default with respect to Indebtedness for
         borrowed money (including but not limited to the Guarantee).

6.       To the best of my knowledge, without any special investigation by me
         other than the laws and documents referred to above, as of the date
         hereof the execution, delivery and performance of the Agreement, any
         borrowings under the Agreement and the execution and delivery of the
         Notes by the Borrower (a) will not (i) violate (A) any provision of Law
         (including, without limitation, Regulations G, U, T, and X of the
         Federal Reserve Board), any order of any court or other agency of
         government or (B) any indenture, agreement or other instrument to which
         the Company or any Subsidiary of the Company is a party, or by which it
         or any of its property is bound, (ii) be in conflict with, result in a
         breach of or constitute (with due notice or lapse of time or both) a
         default under any such indenture, agreement or other instrument or
         (iii) result in the creation or imposition of any lien, charge or
         encumbrance of any nature whatsoever upon any property or assets of the
         Borrower or any Subsidiary of the Borrower and (b) do not require the
         Borrower or any Subsidiary to obtain the consent or approval of any
         Federal, State, municipal or other governmental

                                                                 .    .     .

         department, commission, board, bureau, agency or instrumentality,
         domestic or foreign.

7.       Neither the Borrower nor any Subsidiary thereof is subject to
         regulation under the Public Utility Holding Company Act of 1935, the
         Federal Power Act, or the Investment Company Act of 1940. Neither the
         Borrower nor any Subsidiary thereof is an "investment company" or a
         company "controlled" by an "investment company," within the meaning of
         the Investment Company Act of 1940, as amended.

8.       The Agreement and the Revolving Credit Notes have each been duly
         executed and delivered and, assuming that the Agreement is a valid and
         binding obligation of you, each constitutes the legal, valid and
         binding obligation of the Borrower, enforceable against the Borrower in
         accordance with its terms, except (a) that such enforcement may be
         subject to bankruptcy, insolvency, reorganization, moratorium or other
         similar laws nor or hereafter in effect relating to creditors' rights
         generally, and (b) such enforcement may be subject to general
         principles of equity (regardless of whether enforcement is sought in a
         proceeding in equity or at law).

9.       To the best of my knowledge after due inquiry, there is no pending or
         threatened action, suit, proceeding or investigation by or before any
         Governmental Authority against or affecting the Borrower or any
         Subsidiary of the Borrower, which will more likely than not,
         individually or in the aggregate, have a Material Adverse Effect.

          I am furnishing this opinion to you solely in connection with the
transactions contemplated by the Agreement. This opinion is solely for your
benefit and is not to be used, circulated, quoted or otherwise referred to for
any other purpose without my written permission. In connection with the
transactions contemplated by this Agreement, the law firm of Reed Smith Shaw &
McClay may also rely on this opinion.

                                            Very truly yours,

                                            /s/ John E. Besser

                                                                              to

                        Quarterly Compliance Certificate

         I have conducted a review of the terms and conditions of the Revolving
Credit Agreement dated as of December 1, 1991 (the "Agreement"), the Notes and
the other Loan Documents, and the financial statements of the Borrower. Defined
terms used herein without definition are used as defined in the Agreement. Such
review has not disclosed nor does the signer have any knowledge of the existence
as of the date of this certificate of any condition or event which constitutes a
Potential Default or Event of Default.

         Enclosed are condensed financial statements relating to the most recent
quarter. In my opinion they present fairly the consolidated financial position
of Barnes Group at the end of the quarter and the results of operations for the
indicated periods. These statements were prepared in accordance with generally
accepted accounting principles for interim financial statements.

         Also enclosed are true and correct schedules demonstrating compliance
with the covenants contained in Sections 6.01, 6.02 and 6.03 of the Agreement as
of the date of this certificate.
