Loans outstanding hereunder to the Borrower at any time shall never exceed its

Outstandings. The obligations of each Bank hereunder are several. The failure of
any Bank to perform its obligations hereunder shall not affect the obligations
of any other Bank or the Borrower to any other party nor shall any other party
be liable for the failure of such Bank to perform its obligations hereunder. The
Banks shall have no obligation to make Revolving Credit Loans hereunder on or
after the Expiration Date.

or warrants that its participation in Letters of Credit is without recourse to
the Agent, that it expressly assumes all risk of loss in connection with its
participation therein as if it had issued said Letter of Credit, that it has not
relied upon any statement, information or representation furnished or made by
the Agent and that it has made, and will continue to make, its own independent
investigation, evaluation and analysis of the Borrower and each of the other
Loan Parties, for whose account any Letter of Credit has been or may be issued.
Except as otherwise expressly provided herein, the Agent has no duty or
responsibility, either initially or on a continuing basis, to provide any Bank
with any credit, financial or other information with respect to the Borrower or
any other Loan Party, whether coming into its possession prior to the issuance
of any Letter of Credit or at any time thereafter.

2.15 Fees with Respect to Letters of Credit.

The Borrower agrees to pay to the Agent for the
ratable accounts of the Banks a fee for Letters of Credit from time to time
outstanding, computed on the average daily amount of Letters of Credit
Outstandings at the rate per annum equal to the Revolving Credit Euro-Rate
Spread (computed on the basis of a year of 365 or 366 days, as the case may be,
and actual days lapsed). Such Letter of Credit fee shall be payable in arrears
on the first Business Day of each October, January, April and July after the
date hereof and on the Expiration Date. The Borrower shall also pay to the Agent
for the Agent's sole account the Agent's then in effect customary fees
(excluding fronting fees which the Agent shall not charge) and such
administrative expenses payable with respect to the Letters of Credit as the
Agent may generally charge or incur from time to time in connection with the
issuance, maintenance, modification (if any), assignment or transfer (if any),
negotiation and administration of Letters of Credit.

3. TERM LOANS

3.1 Term Loan Commitments.

Subject to the terms and conditions hereof, relying upon the
representations and warranties herein set forth and without any requirement of
written notice from the Borrower, each Bank severally shall make a term loan
(the "Term Loan") to the Borrower on the Closing Date in such principal amount
equal to such Bank's Term Loan Commitment.

3.2 Nature of Banks' Obligations with Respect to Term
Loans.

The failure of any Bank to make a Term Loan shall not relieve
any other Bank of its obligations to make a Term Loan nor shall it impose any
additional liability on any other Bank hereunder. The Banks shall have no
obligation to make Term Loans hereunder after the Closing Date. The Term Loan
Commitments are not revolving credit commitments and the Borrower shall not have
the right to borrow, repay and reborrow under Section 3.1.

3.3 Term Loan Notes.

The Obligation of the Borrower to repay the unpaid principal
amount of the Term Loans made to it by each Bank, together with interest
thereon, shall be evidenced by a

-38-

Term Note dated the Closing Date payable to the order of each Bank in a face
amount equal to the Term Loan of such Bank. The principal amount of the Term
Notes shall be payable in 28 quarterly installments, in the amounts set forth in
the grid below for payments due during the periods set forth in such grid.
Payments of principal of the Term Notes shall be due on the first Business Day
of each calendar quarter with the first such payment due on January 1, 1997 and
the last such payment due on October 1, 2003.

Amount of Each
Quarterly Payment
Period Due During Period

Revolving Credit Base Rate Option or Revolving Credit Euro-Rate Option set forth
below applicable to the Revolving Credit Loans or the Term Loan Base Rate Option
or Term Loan Euro-Rate Option set forth below applicable to the Term Loans, it
being understood that subject to the provisions of this Agreement, the

-39-

Borrower may select different Interest Rate Options and different Interest
Periods to apply simultaneously to the Loans comprising different Borrowing
Tranches and may convert to or renew one or more Interest Rate Options with
respect to all or any portion of the Loans comprising any Borrowing Tranche
provided that there shall not be at any one time outstanding more than seven (7)
Borrowing Tranches in the aggregate (including the Base Rate Borrowing Tranche
which shall be deemed to be one Borrowing Tranche) and provided further that
only the Base Rate Option shall be applicable with respect to Swing Loans. The
Borrower shall have the right to select from the following Interest Rate Options
applicable to the Revolving Credit Loans:

(a) Revolving Credit Interest Rate Options.

The Borrower shall have the right to select from the
following Interest Rate Options described in clauses (i) and (ii) below to apply
to the Revolving Credit Loans:

of a year of 365 or 366 days, as the case may be, and actual days elapsed) equal
to the Base Rate, such interest rate to change automatically from time to time
effective as of the effective date of each change in the Base Rate; or

(iii) Revolving Credit Euro-Rate Option.

A rate per annum (computed on the basis of a year of
360 days and actual days elapsed) equal to the Euro-Rate plus a percentage rate
per annum (the "Revolving Credit Euro-Rate Spread") which shall be based on the
Leverage Ratio Level then in effect as follows :

Leverage Ratio Level in Effect Revolving Credit Euro-Rate Spread
------------------------------ ---------------------------------

I .50%

VI 1.375%

The Revolving Credit Euro-Rate Spread applicable to all Revolving Credit Loans
outstanding under the Revolving Credit Euro-Rate Option shall change on the
effective date of any change in the Leverage Ratio Level pursuant to the
definition of Leverage Ratio Level.

-40-

(b) Term Loan Interest Rate Options.

The Borrower shall have the right to select from the
Interest Rate Options described in clauses (i) and (ii) below to apply to the
Term Loans.

(i) Term Loan Base Rate Option:
A fluctuating rate per annum (computed on the basis of a year of 365 or 366
days, as the case may be, and actual days elapsed) equal to the Base Rate, such
interest rate to change automatically from time to time effective as of the
effective date of each change in the Base Rate; or

(ii) Term Loan Euro-Rate Option.

A rate per annum (computed on the basis of a year of
360 days and actual days elapsed) equal to the Euro-Rate plus a percentage rate
per annum (the "Term Loan Euro-Rate Spread") which shall be based on the
Leverage Ratio Level in then effect as follows:

Leverage Ratio Level in Effect Term Loan Euro-Rate Spread
------------------------------ --------------------------

I .50%
II .625%
III .75%
IV .875%
V 1.125%
VI 1.375%

The Term Loan Euro-Rate Spread applicable to all Term Loans outstanding under
the Term Loan Euro-Rate Option shall change on the effective date of any change
in the Leverage Ratio Level pursuant to the definition of Leverage Ratio Level.

4.2 Interest Periods.

At any time when the Borrower shall select, convert
to or renew a Euro-Rate Option, the Borrower shall provide at least two (2)
Business Days' notice prior to the commencement of such Euro-Rate Option and
shall elect an interest period during which such Interest Rate Option shall
apply, such periods to be one month in duration until the expiration of the
Syndication Period and one, two, three, six, nine or twelve months thereafter
("Interest Period"), provided that:

(a) any Interest Period which would otherwise end
on a date which is not a Business Day shall be extended to the next succeeding
Business Day unless such Business

-41-

Day falls in the next calendar month, in which case such Interest Period shall
end on the next preceding Business Day;

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

(c) the Euro-Rate Portion for each Interest
Period shall be in integral multiples of $1,000,000 and not less than
$2,000,000 ;

(d) the Borrower shall not select, convert to or
renew an Interest Period for Revolving Credit Loans that would end after the
Expiration Date; and

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

4.3 Default Interest.

To the extent permitted by Law, upon the occurrence
and during the continuation of an Event of Default, the Borrower (x) shall pay
interest on the entire principal amount of the then outstanding Loans, at a rate
per annum equal to two hundred (200) basis points (2% per annum) above the rate
of interest otherwise applicable with respect to such Loans, (y) shall pay
interest on all other Indebtedness due and payable by the Borrower to the Agent
or any Bank arising in connection with this Agreement, at a rate per annum equal
to two hundred (200) basis points (2% per annum) above the rate payable on
Revolving Credit Loans subject to the Base Rate Option and Swing Loans from time
to time, and (z) shall pay fees on Letters of Credit equal to two hundred (200)
basis points (2% per annum) more than the fees otherwise payable under Section
2.15(i). The rate of interest or increased fees payable under this Section 4.3
shall accrue before and after any judgment has been entered. The Borrower
acknowledges that such increased interest rate or fees reflect, among other
things, the fact that such Loans, Letters of Credit or other amounts have become
a substantially greater risk given their default status and that the Banks are
entitled to additional compensation for such risk.

4.4 Euro-Rate Unascertainable.

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

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

(ii) a contingency has occurred which
materially and adversely affects the London interbank market, or

-42-

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

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

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

(iii) if any Bank determines after making
all reasonable efforts that deposits of the relevant amount in Dollars
for the relevant Interest Period for a Loan to which a Euro-Rate Option
applies are not available to such Bank in the London interbank market,

then, in the case of any event specified in subsection (a) above, the Agent
shall promptly so notify the Banks and the Borrower thereof, and in the case of
an event specified in subsection (b) above, such Bank shall promptly so notify
the Agent and endorse a certificate to such notice as to the specific
circumstances of such notice, and the Agent shall promptly send copies of such
notice and certificate to the other Banks and the Borrower. 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 (A) the Banks, in the case of such notice
given by the Agent, or (B) such Bank, in the case of such notice given by such
Bank, to allow the Borrower to select, convert to or renew a Euro-Rate Option
shall be suspended until the Agent shall have later notified the Borrower or
such Bank shall have later notified the Agent of the Agent's or such Bank's, as
the case may be, determination (which determination shall be conclusive absent
manifest error) that the circumstances giving rise to such previous
determination no longer exist. If at any time the Agent makes a determination
under subsection (a) of this Section 4.4 and the Borrower has previously
notified the Agent of its selection of, conversion to or renewal of a Euro-Rate
Option and such Interest Rate Option has not yet gone into effect, such
notification shall be deemed to provide for selection of, conversion to or
renewal of the Base Rate Option otherwise available with respect to such Loans.
If any Bank notifies the Agent of a determination under subsection (b) of this
Section 4.4, the Borrower shall, subject to the Borrower's indemnification
obligations under Section 5.5(b), as to any Loan of the Bank to which a Euro-
Rate Option applies, on the date specified in such notice either convert such
Loan to the Base Rate Option otherwise available with respect to such Loan or
prepay such Loan in accordance with Section 5.4(b) hereof; provided, however,
that with respect to any notice of a determination under subsection (b)(i) of
this Section 4.4, if the Bank can lawfully maintain the Euro-Rate Option through
the end of the Interest Period, the Loan shall be converted to the Base Rate
Option on the last day of the Interest Period. Absent due notice from the
Borrower of conversion or prepayment, such Loan shall automatically be converted
to the Base Rate Option otherwise available with respect to such Loan upon such
specified date.

-43-

4.5 Selection of Interest Rate Options.

If the Borrower fails to select an Interest Period in
accordance with the provisions of Section 4.2 in the case of renewal of the
Euro-Rate Portion, the Borrower shall be deemed to have converted such Loan or
portion thereof to the Base Rate Option otherwise available with respect to such
Loans, commencing upon the last day of that Interest Period.

5. PAYMENTS

5.1 Payments.

All payments and prepayments to be made in respect of
principal, interest, Commitment Fees, Agent's Fees, fees and commissions with
respect to Letters of Credit or other amounts due from the Borrower hereunder
shall be payable prior to 12:00 noon Pittsburgh time on the date when due
without presentment, demand, protest or notice of any kind, all of which are
hereby expressly waived by the Borrower, and without setoff, counterclaim or
other deduction of any nature, and an action therefor shall immediately accrue.
Such payments shall be made to the Agent at the Principal Office for the account
of PNC with respect to the Swing Loans and for the ratable benefit of the Banks
with respect to all other Loans in U.S. Dollars and in immediately available
funds, and the Agent shall promptly distribute such amounts to the Banks in
immediately available funds, provided that in the event payments are received by
12:00 noon Pittsburgh time by the Agent with respect to the Loans and such
payments are not distributed to the Banks on the same day received by the Agent,
the Agent shall pay the Banks the Federal Funds Effective Rate during the first
five (5) calendar days and the Federal Funds Effective Rate plus two percent
(2%) thereafter with respect to the amount of such payments for each day held by
the Agent and not distributed to the Banks. The Agent's and each Bank's
statement of account, ledger or other relevant record shall, in the absence of
manifest error, be conclusive as the statement of the amount of principal of and
interest on the Loans and other amounts owing under this Agreement and shall be
deemed an "account stated."

5.2 Pro Rata Treatment of Banks.

Each borrowing, and each selection of, conversion to
or renewal of any Interest Rate Option, and each payment or prepayment by the
Borrower with respect to principal, interest, Commitment Fees, Facility Fees,
fees and commissions with respect to Letters of Credit or other amounts due from
the Borrower hereunder to the Banks with respect to Loans shall (except as
provided in Section 4.4(b), 5.4(b) or 5.5(a) hereof) be made in proportion to
the amount of such Loans outstanding from each Bank and, if no such Loans are
then outstanding, in proportion to the Ratable Share of each Bank.

5.3 Interest Payment Dates.

Interest on Loans to which a Base Rate Option applies
shall be due and payable in arrears on the first Business Day of each October,
January, April and July after the date hereof, on the Expiration Date and upon
acceleration of the Notes. Interest on Loans to which a Euro-Rate Option applies
shall be due and payable on the last day of each Interest

-44-

Period for those Loans and, if such Interest Period is longer than three months,
also on each quarterly anniversary of such first day of such Interest Period.

5.4 Voluntary Prepayments.

(a) The Borrower shall have the right at its
option from time to time to prepay the Revolving Credit Loans, Swing Loans or
Term Loans in whole or part without premium or penalty (except as provided below
or in Section 5.5 hereof):
(i) on any Business Day with respect to
the Swing Loans and on any day which is a Settlement Date with respect
to any Revolving Credit Loan or Term Loan to which the Base Rate Option
applies,

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

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

(iv) with the Agent's prior approval,
which approval will not be unreasonably withheld, on any Business Day
during an Interest Period with respect to any Loan to which a Euro-Rate
Option applies, provided such prepayment is accompanied by an amount
sufficient to compensate each of the Banks for the costs and losses
reimbursable under Section 5.5(b)(i).

Whenever Borrower desires to prepay any part of the
Revolving Credit Loans, Term Loans or Swing Loans, it shall provide a prepayment
notice to the Agent setting forth the following information:

(x) the date, which shall be a Business
Day and, with respect to prepayment under clause (i) above, a Settlement Date,
on which the proposed prepayment is to be made;

(y) a statement indicating the
application of the prepayment between Revolving Credit Loans, Term Loans and
Swing Loans and if the Borrower is prepaying any of the Term Loans, also a
statement indicating the allocation of such prepayment to unpaid principal
installments which shall be in accordance with Section 5.7(d); and

(z) the total principal amount of such
prepayment, which shall not be less than $250,000 in the case of Revolving
Credit Loans and $2,000,000 and an integral multiple of $500,000 in the case of
Term Loans.

Borrower shall deliver notices of prepayment of
Revolving Credit Loans to the Agent at least one (1) Business Day prior to the
date of such prepayment and of prepayment of the Term Loans at least three (3)
Business Days prior to the date of such

-45-

prepayment. All prepayment notices shall be irrevocable. The principal amount of
the Revolving Credit Loans, Swing Loans or Term Loans for which a prepayment
notice is given shall be due and payable on the date specified in such
prepayment notice as the date on which the proposed prepayment is to be made.

Unless otherwise specified by Borrower with respect
to prepayments of the Euro-Rate Portion of the Loans permitted under (ii) or
(iii) above, all prepayments shall be applied first to the Base Rate Portion and
then to the Euro-Rate Portion of such Loans, subject to Section 5.5(b) hereof.

(b) In the event any Bank (i) gives notice under
Section 4.4(b) or Section 5.5(a) hereof, (ii) does not fund Revolving Credit
Loans because the making of such Loans would contravene Law applicable to such
Bank, or (iii) does not approve any action as to which consent of the Required
Banks is requested by Borrower and obtained hereunder, Borrower shall have the
right, with the consent of the Agent, which shall not be unreasonably withheld,
to prepay the Loans of such Bank in whole, together with all interest accrued
thereon, within ninety (90) days after (x) receipt of such Bank's notice under
Section 4.4(b) or 5.5(a), (y) the date such Bank has failed to fund Revolving
Credit Loans pursuant to Section 7.2 because the making of such Loans would
contravene Law applicable to such Bank, or (z) the date of obtaining the consent
which such Bank has not approved, as applicable, provided Borrower shall also
pay to such Bank at the time of such prepayment any amounts required under
Section 5.5 and accrued Commitment Fees due on such amount, and provided further
that the Revolving Credit Commitment of such Bank shall be provided by all or
part of the remaining Banks or a replacement bank hereunder. The remaining Banks
shall have the right of first refusal to provide the amount of the Revolving
Credit Commitment of the Bank being replaced allocated on a pro rata basis to
the extent necessary.

5.5 Additional Compensation in Certain Circumstances.

(a) Increased Costs or Reduced Return Resulting
from Taxes, Reserves, Capital Adequacy Requirements, Expenses, Etc.

If any Law, guideline or interpretation or
any change in any Law, guideline or interpretation or application thereof by any
Official Body charged with the interpretation or administration thereof, or
compliance with any request or directive (whether or not having the force of
Law) of any central bank or other Official Body:

(i) subjects any Bank to any tax or
changes the basis of taxation with respect to this Agreement, the
Notes, the Loans or payments by the Borrower of principal, interest,
Commitment Fees or other amounts due from the Borrower hereunder or
under the Notes (except for taxes, including any franchise tax, on the
overall net income of such Bank),

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

-46-

(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 Bank, or (B) otherwise applicable to the
obligations of any Bank under this Agreement,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by or impose any expense (including loss of margin) upon any
Bank with respect to this Agreement, the Notes or the making, maintenance or
funding of any part of the Loans (or, in the case of any capital adequacy or
similar requirement, to have the effect of reducing the rate of return on any
Bank's capital, taking into consideration such Bank's customary policies with
respect to capital adequacy) by an amount which such Bank in its sole discretion
deems to be material, such Bank may from time to time notify the Borrower and
the Agent of the amount determined in good faith (using any averaging and
attribution methods employed in good faith) by such Bank (which determination
shall be conclusive absent manifest error) to be necessary to compensate such
Bank for such increase in cost, reduction of income or additional expense. Such
notice shall be delivered within one (1) year of such Bank becoming aware of the
increased costs or reduced return and shall set forth in reasonable detail the
basis for such determination. Such amount shall be due and payable by the
Borrower to such Bank ten (10) Business Days after such notice is given. Each
Bank agrees to use its reasonable efforts, at the request of the Borrower, to
make, fund or maintain any affected Euro-Rate Loans through another lending
office of the Bank if as a result thereof the amount payable to such Bank under
this Section in respect of such Loans would be materially reduced, but only to
the extent not inconsistent with such Bank's internal policies and not otherwise
materially adversely affecting such Bank or such Bank's Loans, as determined by
the Bank in its sole discretion, and provided the Borrower pays all reasonable
expenses incurred by such Bank in using another lending office.

(b) Indemnity.

In addition to the compensation required by
subsection (a) of this Section 5.5, the Borrower shall indemnify each Bank
against any loss or expense (including loss of margin and any loss incurred in
liquidating or employing deposits from third parties) which such Bank sustains
or incurs as a consequence of any

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

(ii) attempt by the Borrower to revoke
(expressly, by later inconsistent notices or otherwise) in whole or
part any notice relating to Revolving Credit Loan Requests under
Section 5.4(a) or prepayments under Section 5.4.

If any Bank sustains or incurs any such loss or expense, it shall from time to
time notify the Borrower of the amount determined in good faith by such Bank
(which determination shall be conclusive absent manifest error) to be necessary
to indemnify such Bank for such loss or expense within one (1) year of such Bank
becoming aware of such loss or expense. Such notice shall set forth in
reasonable detail the basis for such determination. Such amount shall be due

-47-

and payable by the Borrower to such Bank ten (10) Business Days after such
notice is given. Each Bank agrees that, as promptly as practicable after it
becomes aware of the occurrence of an event or the existence of a condition that
would cause it to be affected by any of the events described in Section 5.5(a),
it will make, fund or maintain the affected Loans of such Bank through another
lending office or take such other actions as are reasonably appropriate if (i)
as a result thereof the additional moneys which would otherwise be required to
be paid in respect of such Loans pursuant to this Section 5.5(b) would be
reduced or the illegality or other adverse circumstances would cease to exist
and (ii) as determined by such Bank in its sole discretion, the making, funding
or maintaining of such affected Loans through such other lending office or the
taking of such other actions would not otherwise be disadvantageous to such Bank
for any reason; provided that such Bank will not be obligated to use such other
lending office unless Borrower agrees to pay all expenses incurred by such Bank
in utilizing such lending office.

5.6 Settlement Date Procedures.

In order to minimize the transfer of funds between
the Banks and the Agent, the Borrower may borrow, repay and reborrow Swing
Loans, and PNC may make Swing Loans, as provided in Section 2.1(b) hereof during
the period between Settlement Dates. On each Settlement Date, the Banks agree
among themselves to effect a settlement so that each Bank shall have its Ratable
Share of all Revolving Credit Loans (including those Revolving Credit Loans
designated by PNC as Swing Loans) outstanding as of the close of business on the
Business Day immediately preceding such Settlement Date. Not later than 10:00
a.m. on each Settlement Date when Swing Loans are outstanding, the Agent shall
notify each Bank of its Ratable Share of the Revolving Credit Loans outstanding
as of the close of business on the Business Day immediately preceding such
Settlement Date. Prior to 3:00 p.m. Pittsburgh time on such Settlement Date,
each Bank shall pay to the Agent the amount, if any, necessary to effectuate the
settlement contemplated by this Section, and the Agent shall promptly pay to
each Bank its Ratable Share of all payments, if any, made by the Borrower to the
Agent with respect to the Revolving Credit Loans and any payments due such Bank
in settlement under this Section. The Agent shall also effect settlement in
accordance with this Section on the proposed Borrowing Dates for all Revolving
Credit Loans and may at its option effect settlement on any other Business Day.
If an Event of Default shall occur and on the date of such occurrence the sum of
PNC's Revolving Credit Loans shall be less than PNC's Ratable Share of all
Revolving Credit Loans, PNC shall pay to the Agent the amount, if any, necessary
to effectuate the settlement between the Banks as contemplated by this Section.
These settlement procedures are established solely as a matter of administrative
convenience, and nothing contained in this Section 5.6 shall relieve the Banks
of their obligations to fund Revolving Credit Loans on dates other than a
Settlement Date pursuant to Section 2.9. PNC may at any time, at its option, for
any reason whatsoever require each Bank to pay immediately to PNC such Bank's
Ratable Share of the outstanding Swing Loans, and each Bank may at any time
require the Agent to pay immediately to such Bank its Ratable Share of all
payments made by the Borrower to the Agent with respect to the Revolving Credit
Loans.

-48-

5.7 Mandatory Prepayments.

(a) Borrowing Base Exceeded. Whenever the
outstanding principal balance of Revolving Credit Loans by the Banks plus the
Letter of Credit Outstandings exceed the Borrowing Base, the Borrower shall
make, within five (5) Business Days after the Borrower learns of such excess and
whether or not the Agent has given notice to such effect, a mandatory prepayment
of principal equal to the excess of the outstanding principal balance of the
Revolving Credit Loans over the Borrowing Base, together with accrued interest
on such principal amount.

(b) Excess Cash Flow.

Within twenty (20) Business Days of delivery of the
Borrower's annual financial statements pursuant to Section 8.3(b), but in any
event no later than the date (each, a "Mandatory Prepayment Date") which is five
(5) Business Days after the due date for the delivery of such financial
statements, of each year during the term hereof beginning with the financial
statements for the fiscal year ending December 31, 1997, the Borrower shall make
a mandatory prepayment of principal on the Term Loans computed as set forth in
this Section 5.7(b) below (each, a "Mandatory Prepayment of Excess Cash Flow").
The amount of such Mandatory Prepayment of Excess Cash Flow shall be equal to
60% of Excess Cash Flow (i) for the immediately preceding five fiscal quarters
if the computation is made in 1998 after the due date for delivery of the 1997
financial statements and (ii) for the immediately preceding fiscal year for all
computations made after 1998 (in respect of the financial statements for 1998
and each subsequent year). Each Mandatory Prepayment of Excess Cash Flow shall
be computed as the sum of Excess Cash Flow (whether positive or negative) for
each quarter during the applicable period and shall be subject to a credit for
voluntary prepayments made pursuant to Section 5.4 between the immediately
preceding Mandatory Prepayment Date (or the Closing Date if there have been no
prior Mandatory Prepayment Dates) and the current Mandatory Prepayment Date.
Borrower shall pay any accrued interest on principal being prepaid on the date
on which Borrower makes each Mandatory Prepayment of Excess Cash Flow. If a
Mandatory Prepayment of Excess Cash Flow would cause the outstanding principal
amount of the Term Loans to be less than $50,000,000, such prepayment shall be
limited to the amount necessary to reduce the principal amount of the Term Loans
outstanding to equal $50,000,000 and thereafter Borrower shall not be required
to make any Mandatory Prepayments of Excess Cash Flow pursuant to this Section
5.7(b).

Within ten (10) Business Days of any sale of assets

Loan Party will pay and will cause each of its Subsidiaries to pay all such

reasonable detail and at such reasonable times and as often as the Agent or any
of the Banks may reasonably request, provided each Bank shall provide the
Borrower and the Agent (if the visit involves any examination of properties,
books or records) with reasonable notice prior to any visit or inspection. In

Each Loan Party shall, and shall cause each
of its Subsidiaries to, comply with all applicable Laws, including all
Environmental Laws, in all respects, provided that it shall not be deemed to be
a violation of this Section 8.1(h) as the result of any failure to comply with
any Law if such failure to comply would not result in fines, penalties, other
similar liabilities or injunctive relief which in the aggregate would result in
a Material Adverse Change.

(i) Ownership of the Restricted Subsidiaries.

Borrower shall directly or indirectly own all
of the issued and outstanding capital stock of CBCC, ▇▇▇▇▇▇▇ Tube, Holco and
each of Borrower's other Restricted Subsidiaries.

The Borrower shall comply, and cause each
member of the ERISA Group to comply, with ERISA, the Internal Revenue Code and
other applicable Laws except where such failure, alone or in conjunction with
any other failure, would not result in a Material Adverse Change and such
failure would not affect the validity of the Loans. Without limiting the
generality of the foregoing, the Borrower shall cause all of its Plans and all
Plans maintained by any member of the ERISA Group to be funded in accordance
with the minimum funding requirements of ERISA and shall make, and cause each
member of the ERISA Group to make, in a timely manner, all contributions due to

its expense, faithfully preserve and protect the Agent's Lien on and Prior
Security Interest in the Collateral as a continuing first priority perfected
Lien, subject only to Permitted Liens, and shall do such other acts and things

subsections (l) or (m) of Section 9.1 hereof shall occur, the Banks and the
Agent shall be under no further obligation to make Loans or issue Letters of
Credit hereunder, and the unpaid principal amount of the Notes then outstanding
and all interest accrued thereon and all other Indebtedness of the Loan Parties

under any other Senior Loan Document or any participant of such Bank which has
agreed in writing to be bound by the provisions of Section 10.13 hereof and any
branch, Subsidiary or Affiliate of such Bank or participant anywhere in the

to, and any other funds held in any manner for the account of, any Loan Party by
such Bank or participant or by such branch, Subsidiary or Affiliate, including,

general or special, provisionally credited or finally credited, or otherwise)
now or hereafter maintained by any Loan Party for its own account (but not
including funds held in custodian or trust accounts) with such Bank or
participant or such branch, Subsidiary or Affiliate. Such right shall exist
whether or not any Bank or the Agent shall have made any demand under this
Agreement or any other Senior Loan Document, whether or not such debt owing to
or funds held for the account of the Loan Party is or are matured or unmatured
and regardless of the existence or adequacy of any Collateral, Guaranty or any
other security, right or remedy available to any Bank or the Agent; and

or from the exercise of any other remedy by the Agent shall be applied as
follows:

the Loan Parties under any of the Senior Loan Documents, including
advances made by the Banks or any one of them or the Agent for the
reasonable maintenance, preservation, protection or enforcement of, or
realization upon, the Collateral, including advances for taxes,

on, any of the Collateral;

(ii) second, to the repayment of all
Indebtedness then due and unpaid of the Loan Parties to the Banks
incurred under this Agreement or any of the

-89-

Senior Loan Documents, whether of principal, interest, fees, expenses
or otherwise, in such manner as the Agent may determine in its
discretion; and

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

(e) In addition to all of the rights and remedies
contained in this Agreement or in any of the other Senior Loan Documents, the
Agent shall have all of the rights and remedies of a secured party under the
Uniform Commercial Code or other applicable Law, all of which rights and
remedies shall be cumulative and non-exclusive, to the extent permitted by Law.
The Agent may, and upon the request of the Required Banks shall, exercise all
post- default rights granted to the Agent and the Banks under the Senior Loan
Documents or applicable Law.

9.3 Notice of Sale.

Any notice required to be given by the Agent of a sale, lease,
or other disposition of the Collateral or any other intended action by the

other Senior Loan Documents and any other instruments and agreements referred to
herein, and to exercise such powers and to perform such duties hereunder as are

Agent on behalf of the Banks to the extent provided in this Agreement.

any attorneys, accountants or other experts concerning all matters pertaining to

The duties of the Agent shall be mechanical and administrative in nature; the
Agent shall not have by reason of this Agreement a fiduciary relationship in
respect of any Bank; and nothing in this Agreement, expressed or implied, is
intended to or shall be so construed as to impose upon the Agent any obligations
in respect of this Agreement except as expressly set forth herein. Each Bank
expressly acknowledges (i) that the Agent has not made any representations or
warranties to it and that no act by the Agent hereafter taken, including any
review of the affairs of the Loan Parties and their Affiliates, shall be deemed
to constitute any representation or warranty by the Agent to any Bank; (ii) that
it has made and will continue to make, without reliance upon the Agent, its own
independent investigation of the financial condition and affairs and its own
appraisal of the creditworthiness of the Loan Parties in connection with this
Agreement and the making and continuance of the Loans hereunder; and (iii)
except as expressly provided herein, that the Agent shall have no duty or

10.4 Actions in Discretion of Agent; Instructions from the
Banks.

specifically requires the consent of the Required Banks or all of the Banks. Any
action taken or failure to act pursuant to such instructions or discretion shall
be binding on the Banks, subject to Section 10.6 hereof. Subject to the
provisions of Section 10.6, no Bank shall have any right of action whatsoever
against the Agent as a result of the Agent acting or refraining from acting
hereunder in accordance with the instructions of the Required Banks or, in the
absence of such instructions, in the absolute discretion of the Agent.

assignments by PNC Bank to other banks after the Closing Date and before the end

or any other Senior Loan Documents or any action taken or omitted by the Agent
hereunder or thereunder, provided that the Borrower shall not be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements (a) if the same results from
the Agent's gross negligence or willful misconduct, (b) if the Borrower was not
given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense, or (c) if the same results from a compromise or
settlement agreement entered into without the consent of the Borrower. In
addition, the Borrower agrees to reimburse and pay all reasonable out of pocket
expenses of the Agent's regular employees and agent engaged not more frequently
than quarterly to perform audits of the Loan Parties' books, records and

connection with this Agreement or any other Senior Loan Documents, or (c) be
under any obligation to any of the Banks to ascertain or to inquire as to the

Potential Default.

10.7 Reimbursement and Indemnification of Agent by Banks.

Each Bank agrees to reimburse and indemnify the Agent
(to the extent not reimbursed by the Borrower and without limiting the obliga-
tion of the Borrower to do so) in proportion to its Ratable Share from and
against all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Senior Loan Documents or any action taken or omitted by the Agent
hereunder or thereunder, provided that no Bank shall be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements (a) if the same results from
the Agent's gross negligence or willful misconduct, or (b) if such Bank was not
given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense, or (c) if the same results from a compromise
and settlement agreement entered into without the consent of such Bank. In
addition, each Bank agrees promptly upon demand to reimburse the Agent (to the
extent not reimbursed by the Borrower and without limiting the Obligation of the
Borrower to do so) in proportion to its Ratable Share for all amounts due and
payable by the Borrower to the Agent in connection with the Agent's periodic
audit of the Loan Parties' books, records and business properties.

-92-

10.8 Reliance by Agent.

The Agent shall be entitled to rely upon any writing,
telegram, telex or teletype message, resolution, notice, consent, certificate,
letter, cablegram, statement, order or other document or conversation by
telephone or otherwise believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons, and upon the advice and
opinions of counsel and other professional advisers selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action
hereunder unless it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action.

10.9 Notice of Default.

The Agent shall not be deemed to have knowledge or
notice of the occurrence of any Potential Default or Event of Default unless the
Agent has received notice from a Bank or the Borrower referring to this
Agreement, describing such Potential Default or Event of Default and stating
that such notice is a "notice of default."

10.10 Notices.

The Agent shall promptly send to each Bank a copy of
all notices received from the Borrower or the Company pursuant to the provisions
of this Agreement or the other Senior Loan Documents promptly upon receipt
thereof. The Agent shall promptly notify the Borrower and the other Banks of
each change in the Base Rate and the effective date thereof.

10.11 PNC and the Banks in Their Individual Capacities.

With respect to its Commitments and the Loans made by
it, the Agent shall have the same rights and powers hereunder as any other Bank
and may exercise the same as though it were not the Agent, and the term "Banks"
shall, unless the context otherwise indicates, include the Agent in its
individual capacity. PNC and its Affiliates and each of the Banks and their
respective Affiliates may, without liability to account, except as prohibited
herein, make loans to, accept deposits from, discount drafts for, act as trustee
under indentures of, and generally engage in any kind of banking or trust
business with the Loan Parties and their respective Affiliates, in the case of
the Agent, as though it were not acting as Agent hereunder and, in the case of
each Bank, as though such Bank were not a Bank hereunder.

10.12 Holders of Notes.

The Agent may deem and treat any payee of any Note as
the owner thereof for all purposes hereof unless and until written notice of the
assignment or transfer thereof shall have been filed with the Agent. Any
request, authority or consent of any Person who at the time of making such
request or giving such authority or consent is the holder of any Note shall be
conclusive and binding on any subsequent holder, transferee or assignee of such
Note or of any Note or Notes issued in exchange therefor.

-93-

10.13 Equalization of Banks.

The Banks and the holders of any participations in
any Note agree among themselves that, with respect to all amounts received by
any Bank or any such holder for application on any obligation hereunder or under
any Note or under any such participation, whether received by voluntary payment,
by realization upon security, by the exercise of the right of setoff or banker's
lien, by counterclaim or by any other non-pro rata source, equitable adjustment
will be made in the manner stated in the following sentence so that, in effect,
all such excess amounts will be shared ratably among the Banks and such holders
in proportion to their interests in payments under the Notes, except as
otherwise provided in Section 4.4(b), 5.4(b) or 5.5 hereof. The Banks or any
such holder receiving any such amount shall purchase for cash from each of the
other Banks an interest in such Bank's Loans in such amount as shall result in a
ratable participation by the Banks and each such holder in the aggregate unpaid
amount under the Notes, provided that if all or any portion of such excess
amount is thereafter recovered from the Bank or the holder 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 (including court order) to be paid by the Bank or the holder making such
purchase.

10.14 Successor Agent.

The Agent may resign as Agent upon not less than
thirty (30) days' prior written notice to the Borrower and the Banks. If the
Agent shall resign under this Agreement, then either (a) the Required Banks
shall appoint from among the Banks a successor agent for the Banks which
appointment shall be subject to the consent of the Borrower which shall not be
unreasonably withheld provided that if the Agent requests such consent and
Borrower does not within thirty (30) days following such request either consent
to such appointment or select a successor agent from among the Banks and such
successor shall assume in writing the obligations of the Agent, then the Agent
shall no longer be required to obtain the Borrower's consent to assign its
rights and obligations as Agent hereunder to another Bank or (b) if a successor
agent shall not be so appointed and approved within the thirty (30) day period
following the Agent's notice to the Banks of its resignation, then the Agent
shall appoint, with the consent of the Borrower, which consent shall not be
unreasonably withheld, a successor agent who shall serve as Agent until such
time as the Required Banks appoint a successor agent. Upon its appointment
pursuant to either clause (a) or (b) above, such successor agent shall succeed
to the rights, powers and duties of the Agent and the term "Agent" shall mean
such successor agent, effective upon its appointment, and the former Agent's
rights, powers and duties as Agent shall be terminated without any other or
further act or deed on the part of such former Agent or any of the parties to
this Agreement. After the resignation of any Agent hereunder, the provisions of
this Article 10 shall inure to the benefit of such former Agent, and such former
Agent shall not by reason of such resignation be deemed to be released from
liability for any actions taken or not taken by it while it was an Agent under
this Agreement.

10.15 Agent's Fee.

The Borrower shall pay to the Agent the nonrefundable
fee (the "Agent's Fee") agreed to in the letter agreement between Borrower and
the Agent dated as of the Closing

-94-

Date, as amended from time to time (the "Agent's Fee Letter"), until all of the
Loans and other obligations of Borrower hereunder shall be paid in full, all
Letters of Credit shall have expired or been terminated and the Revolving Credit
Commitments are terminated.

10.16 Beneficiaries.

Except to the extent provided in Sections 10.5,
10.14, 10.15 and 10.18, the provisions of this Article 10 are solely for the
benefit of the Agent and the Banks, and the Loan Parties shall not have any
rights to rely on or enforce any of the provisions hereof. In performing its
functions and duties under this Agreement, the Agent shall act solely as agent
of the Banks and does not assume, and shall not be deemed to have assumed, any
obligation toward or relationship of agency or trust with or for any of the Loan
Parties.

10.17 Availability of Funds.

Unless the Agent shall have been notified by a Bank
prior to the date upon which a Loan is to be made that such Bank does not intend
to make available to the Agent such Bank's portion of such Loan, the Agent may
assume that such Bank has made or will make such proceeds available to the Agent
on such date and the Agent may, in reliance upon such assumption (but shall not
be required to), make available to the Borrower a corresponding amount. If such
corresponding amount is not in fact made available to the Agent by such Bank,
the Agent shall be entitled to recover such amount on demand from such Bank (or,
if such Bank fails to pay such amount forthwith upon such demand, from the
Borrower) and shall also be entitled to all interest accrued thereon, in respect
of each day during the period commencing on the date such amount was made
available to the Borrower and ending on the date the Agent recovers such amount,
at a rate per annum equal to the applicable interest rate in respect of the
Loan.

10.18 Calculations.

In the absence of gross negligence or willful
misconduct, the Agent shall not be liable for any error in computing the amount
payable to any Bank whether in respect of the Loans, fees or any other amounts
due to the Banks under this Agreement. In the event an error in computing any
amount payable to any Bank is made, the Agent, each of the Loan Parties and each
affected Bank shall, forthwith upon discovery of such error, make such
adjustments as shall be required to correct such error, and any compensation
therefor will be calculated at the Federal Funds Effective Rate.

11. MISCELLANEOUS

11.1 Modifications, Amendments or Waivers.

With the written consent of the Required Banks, the
Agent, acting on behalf of all the Banks, and the Loan Parties may from time to
time enter into written agreements amending or changing any provision of this
Agreement or any other Senior Loan Document or the rights of the Banks or the
Loan Parties hereunder or thereunder, or may grant

-95-

written waivers or consents to a departure from the due performance of the
obligations of the Loan Parties hereunder or thereunder. Any such agreement,
waiver or consent made with such written consent shall be effective to bind all
the Banks and the Loan Parties provided, that no such agreement, waiver or
consent may be made which will:

(i) Except as provided in Section 5.4(b), reduce or
increase the amount of the Commitment of any Bank hereunder, or alter
the provisions relating to any fee or other amount payable to any Bank
hereunder, or amend Sections 5.2, 10.6 and 10.13 hereof, without the
written consent of all the Banks; or

(ii) Whether or not any Loans are outstanding, extend
the time for payment of principal or interest of any Loan, or reduce
the principal amount of or the rate of interest borne by any Loan, or
otherwise affect the terms of payment of the principal of or interest
of any Loan, without the written consent of the Bank to whom such Loan
is owed; or

(iii) Waive the requirements of Section 8.1(a); or

(iv) Amend this Section 11.1, change the definition of
Required Banks or change any requirement providing for the Banks or the
Required Banks to authorize the taking of any action hereunder, without
the written consent of all the Banks.

(v) Except for sales of assets permitted by
Section 8.2(h) without the written consent of all of the Banks (with respect to
which the Agent shall release any Liens it holds on such assets), release any
Collateral, any Guarantor from its Obligations under the Guaranty Agreement or
any other security for any of the Loan Parties' obligations; or

No agreement, waiver or consent which would modify
the interests, rights or obligations of the Agent in its capacity as Agent or as
the issuer of Letters of Credit shall be effective without the written consent
of the Agent. The Agent and the Borrower may modify the Agent's Fee Letter
without the consent of or notice to any of the other Banks.

11.2 No Implied Waivers; Cumulative Remedies; Writing
Required.

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

11.3 Reimbursement and Indemnification of Banks by the
Borrower; Taxes.

The Borrower agrees unconditionally upon demand to
pay or reimburse to each Bank and to save such Bank harmless against (i)
liability for the payment of all reasonable out-of-pocket costs, expenses and
disbursements, including but not limited to reasonable fees and expenses of
counsel, incurred by such Bank (a) relating to any amendments, waivers or
consents pursuant to the provisions hereof, and (b) in connection with any
workout or restructuring, or in connection with the protection, preservation,
exercise or enforcement of this Agreement or any other Senior Loan Document or
collection of amounts due hereunder or thereunder or the proof and allowability
of any claim arising under this Agreement or any other Senior Loan Document,
whether in bankruptcy or receivership proceedings or otherwise, and (ii) all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against such Bank, in its capacity as such,
in any way relating to or arising out of this Agreement or any other Senior Loan
Documents or any action taken or omitted by such Bank hereunder or thereunder,
provided that the Borrower shall not be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements (a) if the same results from such Bank's gross
negligence or willful misconduct, (b) if the Borrower was not given notice of
the subject claim and the opportunity to participate in the defense thereof, at
its expense, or (c) if the same results from a compromise or settlement
agreement entered into without the consent of the Borrower. The Banks will
attempt to minimize the fees and expenses of legal counsel for the Banks which
are subject to reimbursement by the Borrower hereunder by considering the usage
of one law firm to represent the Banks and the Agent if appropriate under the
circumstances. The Borrower agrees unconditionally to pay all stamp, document,
transfer, recording or filing taxes or fees and similar impositions (except for
taxes, including any franchise tax, on the overall net income of any Bank or the
Agent) now or hereafter determined by the Agent or any Bank to be payable in
connection with this Agreement or any other Senior Loan Document, and the
Borrower agrees unconditionally to save the Agent and the Banks harmless from
and against any and all present or future claims, liabilities or losses with
respect to or resulting from any omission to pay or delay in paying any such
taxes, fees or impositions.

11.4 Holidays.

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

11.5 Funding by Branch, Subsidiary or Affiliate.

(a) Notional Funding.

Each Bank shall have the right from time to
time, without notice to the Borrower, to deem any branch, Subsidiary or
Affiliate (which for the purposes of this Section 11.5 shall mean any
corporation or association which is directly or indirectly controlled

-97-

by or is under direct or indirect common control with any corporation or
association which directly or indirectly controls such Bank) of such Bank to
have made, maintained or funded any Loan to which the Euro-Rate Option applies
at any time, provided that immediately following (on the assumption that a
payment were then due from the Borrower to such other office) and as a result of
such change the Borrower would not be under any greater financial obligation
pursuant to Section 5.5 hereof than it would have been in the absence of such
change. Notional funding offices may be selected by each Bank without regard to
the Bank's actual methods of making, maintaining or funding the Loans or any
sources of funding actually used by or available to such Bank.

(b) Actual Funding.

Each Bank shall have the right from time to
time to make or maintain any Loan by arranging for a branch, Subsidiary or
Affiliate of such Bank to make or maintain such Loan subject to the last
sentence of this Section 11.5(b). If any Bank causes a branch, Subsidiary or
Affiliate to make or maintain any part of the Loans hereunder, all terms and
conditions of this Agreement shall, except where the context clearly requires
otherwise, be applicable to such part of the Loans to the same extent as if such
Loan were made or maintained by such Bank, but in no event shall any Bank's use
of such a branch, Subsidiary or Affiliate to make or maintain any part of the
Loans hereunder cause such Bank or such branch, Subsidiary or Affiliate to incur
any costs or expenses payable by the Borrower hereunder or require the Borrower
to pay any other compensation to any Bank (including, without limitation, any
expenses incurred or payable pursuant to Section 5.5 hereof) which would
otherwise not be incurred.

11.6 Notices.

All notices, requests, demands, directions and other
communications (collectively "notices") given to or made upon any party hereto
under the provisions of this Agreement shall be by telephone or in writing
(including telex or facsimile communication) unless otherwise expressly
permitted hereunder and shall be delivered or sent by telex or facsimile to the
respective parties at the addresses and numbers set forth on Schedule 11.6
hereto or in accordance with any subsequent written direction from any party to
the others. All notices shall, except as otherwise expressly herein provided, be
effective (i) in the case of telex or facsimile, when received, (ii) in the case
of hand-delivered notice, when hand-delivered, (iii) in the case of telephone,
when telephoned, provided, however, that in order to be effective, telephonic
notices must be confirmed in writing no later than the next day by letter,
facsimile or telex, (iv) if given by mail, four (4) days after such
communication is deposited in the mails with first- class postage prepaid,
return receipt requested, and (v) if given by any other means (including by air
courier), when delivered; provided, that notices to the Agent with respect to
Revolving Credit Loan Requests and Swing Loan Requests, reduction of the
Revolving Credit Commitments, extensions of the Expiration Date, selection,
conversion or renewal of Interest Rate Options and prepayment notices shall not
be effective until received. Any Bank giving any notice to any Loan Party shall
simultaneously send a copy thereof to the Agent, and the Agent shall promptly
notify the other Banks of the receipt by it of any such notice.

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

11.8 Governing Law.

This Agreement shall be deemed to be a contract under
the laws of the Commonwealth of Pennsylvania and for all purposes shall be
governed by and construed and enforced in accordance with the laws of the

relating to the transactions provided for herein and therein, including any
prior confidentiality agreements and commitments.

11.10 Duration; Survival.

All representations and warranties of the Loan
Parties contained herein or made in connection herewith shall survive the making
of Loans and shall not be waived by the execution and delivery of this
Agreement, any investigation by the Agent or the Banks, the making of Loans, or
payment in full of the Loans and expiration or termination of all Letters of
Credit. All covenants and agreements of the Loan Parties contained in Sections
8.1, 8.2 and 8.3 herein shall continue in full force and effect from and after
the date hereof so long as the Borrower may borrow hereunder and until
termination of the Term Loan Commitments, Revolving Credit Commitments and Swing
Loan Commitment and repayment in full of the Loans and the expiration of all
outstanding Letters of Credit. All covenants and agreements of the Borrower
contained herein relating to the payment of principal, interest, premiums,

11.11 Successors and Assigns.

This Agreement shall be binding upon and shall inure
to the benefit of the Banks, the Agent, the Loan Parties and their respective
successors and assigns, except that none of the Loan Parties may assign or
transfer any of its rights and obligations hereunder or any interest herein.
Each Bank may, at its own cost, make assignments of or sell participations in
all or any part of any Loan or Loans made by it to one or more banks or other
entities, which shall be subject to the consent of the Agent and the Borrower
with respect to any assignee, which

-99-

consent shall not be unreasonably withheld ;provided that no consent of the
Borrower shall be required in the case of an assignment by a Bank to an
Affiliate of such Bank or if an Event of Default exists and is continuing.
Borrower acknowledges that each of the banks under the Existing Credit Agreement
immediately prior to the Closing Date is an acceptable assignee and consents to
an assignment by PNC Bank to such assignee. Assignments may not be made in
amounts less than the lesser of (i) $10,000,000 or (ii) 100% of the Revolving
Credit Commitment and outstanding Term Loans of the assigning Bank; provided,
however, that PNC may assign portions of its Revolving Credit Commitment and
outstanding Term Loans in an amount less than the amount specified in clauses
(i) and (ii) of this sentence so long as such assignment shall not cause the
Commitment of PNC to be less than (i) 25% of the total outstanding Commitments
if no Event of Default exists and is continuing, or (ii) 0% if an Event of
Default exists and is continuing. Any Bank which makes an assignment of any its
Loans or its Commitments must assign a percentage of its Term Loan and its Term
Loan Commitment which is equal to the percentage of its Revolving Credit Loans
and Revolving Credit Commitment which it is assigning. In the case of an
assignment, the Agent shall provide written notice thereof to the Borrower, and
upon receipt and acceptance by the Agent of the written agreement of such
assignee, in substantially the form attached as Exhibit 11.11 hereto, to be
bound by the terms hereof (including this Section 11.11 and Section 11.12) as if
it were an original Bank hereunder, the assignee shall have, to the extent of
such assignment (unless otherwise provided therein), the same rights, benefits
and obligations as it would have if it had been a signatory Bank hereunder, the
Revolving Credit Commitments and Term Loan Commitments shall be adjusted
accordingly, and upon surrender of the Notes subject to such assignment, the
Borrower shall execute and deliver a new Revolving Credit Note to the assignee
in an amount equal to the amount of the Revolving Credit Commitment assumed by
it and a new Term Note in an amount equal to the Term Loan purchased by it and a
new Revolving Credit Note to the assigning Bank in an amount equal to the
Revolving Credit Commitment retained by it hereunder and an new Term Note in an
amount equal to the Term Loan retained by it hereunder. The assigning Bank shall
pay to the Agent a service fee of $3,500 for each assignment. In the case of a
participation, the participant shall only have the rights specified in Section
9.2(c) (the participant's rights against such Bank in respect of such
participation to be those set forth in the agreement executed by such Bank in
favor of the participant relating thereto and not to include any voting rights
except with respect to matters of the type referenced in clauses (i), (ii),
(iii) or (iv) under Section 11.1 hereof), all of such Bank's obligations under
this Agreement or any other Senior Loan Document shall remain unchanged, and all
amounts payable by any Loan Party hereunder or thereunder shall be determined as
if such Bank had not sold such participation. Any assignee or participant which
is not incorporated under the Laws of the United States of America or a state
thereof shall deliver to the Borrower and the Agent the form of certificate
described in Section 11.17 relating to federal income tax withholding. Each Bank
may furnish any publicly available information concerning any Loan Party or its
Affiliates and any other information concerning any Loan Party or its Affiliates
in the possession of such Bank from time to time to assignees and participants
(including prospective assignees or participants) provided such assignees and
participants agree to be bound by the provisions of Section 11.12 hereof.
Notwithstanding anything contained herein to the contrary, each Bank and each
assignee of a Bank hereunder may only make assignments which are pro rata of all
of its rights, benefits and obligations under this Agreement.

connection with their respective capacities as the Agent or as a Bank, as the
case may be, under this Agreement and for the purposes contemplated hereby. The

Bank, assignee or participant which so delivers a Form W-8, W-9, 4224 or 1001
further undertakes to deliver to each of the Borrower and the Agent two (2)
additional copies of such form (or a successor form) on or before the date that
