unless such subsequent Bid Rate Quote is submitted solely to correct a manifest
error in such former Bid Rate Quote. The Agent's notice to the Borrower shall
specify (A) the aggregate principal amount of Bid Rate Loans for which offers
have been received for each Interest Period specified in the related Bid Rate
Quote Request, (B) the respective principal amounts and Bid Rate Margins or

                                     - 30 -
<PAGE>

Bid Rate Absolute Rates, as the case may be, so offered and (C) if applicable,
limitations on the aggregate principal amount of Bid Rate Loans for which offers
in any single Bid Rate Quote may be accepted.

         (v) ACCEPTANCE AND NOTICE BY BORROWER. Not later than 11:00 A.M.
(eastern time) on (x) the third Business Day prior to the proposed date of
Disbursement, in the case of a LIBOR Auction or (y) the proposed date of
Disbursement, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Agent shall have mutually agreed and
shall have informed the Lenders of not later than the date of the Bid Rate Quote
Request for the first LIBOR Auction or Absolute Rate Auction for which such
change is to be effective), the Borrower shall notify the Agent of its
acceptance or non-acceptance of the offers so presented to it pursuant to
Subsection (iv). In the case of acceptance, such notice (a "Notice of Bid Rate
Borrowing") shall specify the aggregate principal amount of offers for each
Interest Period that are accepted and the types of Commitments to be borrowed
against. The Borrower may accept any Bid Rate Quote in whole or in part;
PROVIDED that:

               (A) the aggregate principal amount of each Bid Rate Disbursement
may not exceed the applicable amount set forth in the related Bid Rate Quote
Request,

               (B) the principal amount of each Bid Rate borrowing must be
$5,000,000 or a larger multiple of $1,000,000 (subject to Subsection 2.2c(vi)

ascending Bid Rate Margins or Bid Rate Absolute Rates, as the case may be, and

               (D) the Borrower may not accept any offer that is described in
subsection (iii)(C) of this Section 2.2c or that otherwise fails to comply with
the requirements of this Agreement.

         (vi) ALLOCATION BY AGENT. If offers are made by two or more Lenders
with the same Bid Rate Margins or Bid Rate Absolute Rates, as the case may be,
for a greater aggregate principal amount than the amount in respect of which
such offers are accepted for the related Interest Period, the principal amount
of Bid Rate Loans in respect of which such offers are accepted shall be
allocated by the Agent among such Lenders as nearly as possible (in multiples of
$1,000,000, as the Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determinations by the Agent of the amounts of
Bid Rate Loans shall be conclusive in the absence of manifest error.

         (vii) NOTICE TO LENDERS. If the Borrower accepts one or more of the
offers made by any Lender pursuant to clause (v) of this Section 2.2c above, the
Agent shall in turn promptly notify (A) each Lender of the date of such Bid Rate
Loan, and the aggregate amount, interest rate, type of Commitment to be borrowed
against and maturity of such Bid Rate Loan and whether or not any offer or
offers made by such Lender pursuant to clause (iii) of this Section 2.2c above
have been accepted by the Borrower and (B) each Lender which is to make a Bid
Rate Loan, of the amount of each Bid Rate Loan to be made by such Lender. Each
Lender which is to make a Bid Rate Loan shall, before 1:00 p.m. (Pittsburgh,
Pennsylvania time) on the

pursuant to clause (A) of the preceding sentence or any later time when such
Lender shall have received notice from the Agent pursuant to clause (B) of the
preceding sentence, make available to the Agent such Lender's Bid Rate Loan, in
immediately available funds. Promptly after 1:00 p.m. (Pittsburgh, Pennsylvania
time) and in any event before 3:00 p.m. (Pittsburgh, Pennsylvania time) on each
date of the making of Bid Rate Loans, the Agent shall make the aggregate amount
available to the Borrower.

         (viii) BID RATE LOAN PREPAYMENT. No Bid Rate Loan shall be prepaid
prior to the end of the relevant Bid Rate Interest Period without the prior
consent of the Lender extending such Bid Rate Loan.

2.2d BID RATE LOAN INTEREST. Interest on the Bid Rate Loans for a Bid Rate
Interest Period shall accrue at the rate per annum agreed upon between the
Lender or Lenders making such Bid Rate Loans and the Borrower pursuant to the
Bid Rate selection procedures set forth in Subsection 2.2c above.

2.2e BASE RATE OPTION BORROWING IN EVENT OF CANCELLED BID RATE LOAN REQUEST. In
the event of cancellation by the Borrower of a Bid Rate Loan Request pursuant to
paragraph (v) of Subsection 2.2c, the Borrower may, before 1:00 P.M. (eastern

Disbursement under the Long Term Revolving Credit Commitment or the Short Term
Revolving Credit Commitment to be made on the day of such cancellation and to

to make their respective pro rata shares of such Disbursement available at the
office of the Borrower prior to 2:00 P.M. (eastern time) on the date of such
Disbursement in accordance with the procedures set forth in Subsection
2.1Ae(iii) or Subsection 2.1Be(iii), as applicable.

2.2f REDUCTION OF AVAILABLE COMMITMENTS. While each such Bid Rate Loan is
outstanding hereunder, the outstanding principal amount thereof shall reduce
correspondingly availability under either or both of (i) the Long Term Revolving
Credit Commitment and (ii) the Short Term Revolving Credit Commitment, as
applicable, and shall reduce, as to each Lender availability under either or
both of (i) that Lender's Long Term Revolving Credit Commitment or (ii) that
Lender's Short Term Revolving Credit Commitment, as applicable, by an amount
equal to such Lender's Long Term Revolving Credit Commitment Percentage or
Lender's Short Term Revolving Credit Commitment Percentage, as applicable, of
the aggregate outstanding principal balance of Bid Rate Loans issued by any
Lender.

any Swingline Quote in whole or in part; PROVIDED that:

               (A) the aggregate principal amount of each Swingline Disbursement
may not exceed the applicable amount set forth in the related Swingline Quote
Request,

               (B) the principal amount of each Swingline borrowing must be
$10,000 or a larger multiple of $10,000,

               (C) acceptance of offers may only be made on the basis of
ascending Swingline Interest Rate, and

               (D) the Borrower may not accept any offer that fails to comply
with the requirements of this Agreement.

         (vi) ALLOCATION BY BORROWER. If offers are made by two or more
Swingline Lenders with the same Swingline Interest Rate for a greater aggregate
principal amount than the amount in respect of which such offers are accepted
for the related Swingline Loan, the principal amount of Swingline Loans in
respect of which such offers are accepted shall be allocated by the Borrower
among such Swingline Lenders as nearly as possible (in multiples of $10,000, as
the Agent may deem appropriate) in proportion to the aggregate principal amounts
of such offers. Determinations by the Borrower of the amounts of Swingline Loans
shall be conclusive.

         (vii) SWINGLINE LOAN PREPAYMENT. A Swingline Loan may be prepaid at any
time without the prior consent of the Swingline Lender extending such Swingline
Loan.

                                     - 35 -
<PAGE>

2.3e  RISK PARTICIPATION. Upon the Disbursement of each Swingline Loan and
without any further action by or on behalf of such Lender, each Lender hereby
agrees to purchase, upon the occurrence of an Event of Default, an undivided
full risk non-recourse participation in such Swingline Loan, in an amount equal
to (i) such Lender's Long Term Revolving Credit Commitment Percentage (and in
the event the Long Term Revolving Credit Commitment is fully drawn at the time
of the Disbursement of such Swingline Loan, such Lender's Short Term Revolving
Credit Commitment Percentage), (ii) multiplied by the outstanding principal
amount of such Swingline Loan on the date of the Event of Default; PROVIDED
HOWEVER, no Lender shall participate in any Swingline Loan which Swingline Loan
is made after a notice of an Event of Default has been given. If and to the
extent any Swingline Lender receives payment of principal or interest on a
participated Swingline Loan, such Swingline Lender shall deliver to each Lender
such Lender's pro rata share of such payment.

2.3f  REDUCTION OF AVAILABLE COMMITMENTS. While each such Swingline Loan is
outstanding hereunder, the outstanding principal amount thereof shall
correspondingly reduce availability first under the Long Term Revolving Credit
Commitment and first shall reduce, as to each Lender availability under the
Lender's Long Term Revolving Credit Commitment by an amount equal to such
Lender's Long Term Revolving Credit Commitment Percentage share of the aggregate
outstanding principal balance of Swingline Loans issued by the Agent. If at any
time the sum of the Long Term Revolving Credit Loans outstanding plus the
Swingline Loans outstanding exceed the Long Term Revolving Credit Commitment,
such excess shall correspondingly reduce availability under the Short Term
Revolving Credit Commitment and shall reduce, as to each Lender availability
under the Lender's Short Term Revolving Credit Commitment by an amount equal to
such Lender's Short Term Revolving Credit Commitment Percentage share of such
excess.

2.4  INTEREST RATES, INTEREST PAYMENT AND CERTAIN PROVISIONS RELATING TO
INTEREST AND FEES.

2.4a  PAYMENTS OF INTEREST. The Borrower shall pay interest on the principal
amount of the Loans from time to time outstanding hereunder, from the date

conversion to or renewal of, either in whole or in part, the LIBOR Option on the
third Business Day prior to the proposed effective date for the conversion or
renewal; and (iii) shall set forth:

         (A) the effective date of such conversion or renewal, which shall be a
Business Day;

                                     - 39 -
<PAGE>

         (B) the new LIBOR Interest Period(s) selected; and

         (C) with respect to each such Interest Period, the aggregate principal
amount of the corresponding LIBOR Portion.

         At the expiration of each LIBOR Interest Period, any part (including
the whole) of the principal amount of the corresponding LIBOR Portion as to
which no notice of conversion or renewal has been received as provided above,
shall automatically be converted to the Base Rate Option. At the expiration of
each Bid Rate Interest Period or Swingline Interest Period, any part (including
the whole) of the principal amount of the corresponding Bid Rate Loan or
Swingline Loan, as applicable, as to which no notice of an invitation for bid
has been received as provided in Section 2.2 or Section 2.3, as applicable,
shall automatically be converted to Revolving Credit Loans under the Commitment
to which each was allocated and such principal amount shall bear interest at the
Base Rate Option.

2.4e  NOTIFICATION OF ELECTION OF AN INTEREST RATE OPTION. The Borrower, by an
Authorized Officer, shall notify the Agent of (i) each election or renewal of an
Option and each conversion from one Option to another, (ii) the Portion of the
Long Term Revolving Credit Loans, the Short Term Revolving Credit Loans or the
Term Loans, as applicable, then outstanding to be allocated to each Option and
(iii) where relevant, the Interest Periods applicable to each Option, by
communication as provided for in this Agreement. Any such communication may be
oral or written and if oral, it shall be followed immediately by written
confirmation of such Option election executed by an Authorized Officer.

2.4f  DEFAULT INTEREST. After the occurrence of and during the continuance of an
Event of Default and whether or not judgment has been entered against the
Borrower on the Revolving Credit Notes or the Term Notes, all Base Rate Portions
shall bear interest at a rate per annum which shall be two hundred (200) basis
points (2%) per annum above the rate otherwise in effect under the Base Rate
Option, such interest rate to change automatically from time to time, effective
as of the effective date of each change in the Base Rate. After the occurrence
of and during the continuance of an Event of Default and whether or not judgment
has been entered against the Borrower on the Revolving Credit Notes, the Term
Notes and the Bid Rate Notes, all such LIBOR Portions and Bid Rate Loans shall
bear interest (i) until the end of the then current Interest Period, at a rate
per annum which shall be two hundred (200) basis points (2%) per annum above the
rate otherwise in effect under the LIBOR Option and the Bid Rate Option, as the
case may be, and (ii) at the end of the then current Interest Period, and
thereafter at the sum of (A) the Base Rate PLUS (B) two hundred (200) basis
points (2%) per annum. After the occurrence of and during the continuance of an
Event of Default whether or not judgment has been entered against the Borrower
on the Swingline Notes, all Swingline Loans shall bear interest at the sum of
(A) the Base Rate plus (B) two hundred (200) basis points (2%) per annum.

2.5   YIELD-PROTECTION, CAPITAL ADEQUACY AND MISCELLANEOUS PROVISIONS RELATING
TO LIBOR.

2.5a  YIELD PROTECTION. Notwithstanding other provisions of this Section 2.5:

         (i) If any Governmental Rule (including, without limitation, Regulation
D), or if any change therein on or after the date hereof, or in the
interpretation thereof by any Governmental Authority charged with the
administration thereof, shall:

               (A) subject any Lender to any tax, levy, impost, charge, fee,
duty, deduction or withholding of any kind with respect to payments of principal
or interest or other amounts due hereunder (other than any tax imposed or based
upon the income of a Lender and payable to any Governmental Authority in the
United States of America or any state thereof); or

               (B) change the basis of taxation of any Lender with respect to
payments of principal or interest or other amounts due hereunder (other than any
change which affects, and only to the extent that it affects, the taxation by
the United States or any state thereof of the total net income of such Lender);
or

               (C) impose, modify or deem applicable any reserve, special
deposit or similar requirements against assets held by any Lender applicable to
the Letters of Credit Outstanding or to the Commitment or Loans made hereunder
(other than such requirements which are included in the determination of the
applicable rate of interest hereunder); or

               (D) impose upon any Lender any other obligation or condition with
respect to this Agreement,

and the result of any of the foregoing is to increase the cost to the affected
Lender, reduce the income receivable by the affected Lender, reduce the rate of
return on the affected Lender's capital, or impose any expenses upon the
affected Lender, all with respect to any of the Commitments, the Loans or the
Letters of Credit Outstanding (or any portion thereof) by an amount which the
affected Lender reasonably deems material, and if the affected Lender is then
demanding similar compensation for such occurrences from other borrowers who are
similarly situated and who have a similar relationship with the affected Lender
and from which the affected Lender has the right to demand such compensation,
then and in any such case:

                    (1) the affected Lender shall promptly notify the Borrower
of the happening of such event;

                    (2) the Borrower shall pay to the affected Lender, on
demand, such amount as will compensate the affected Lender for such reduction in
its rate of return; and

                    (3) the Borrower may pay the affected portion of the
affected Lender's Commitments, Loans or interest in the Letters of Credit
Outstanding in full without the payment of any additional amount, including
prepayment penalties, other than amounts payable on account of the affected
Lender's out-of-pocket losses (including funding loss, if any, as

                                     - 41 -
<PAGE>

provided in Section 2.11) which are not otherwise provided for in subparagraph
(2) immediately above.

         (ii) A certificate as to the increased cost or reduced amount as a
result of any event mentioned in this Subsection 2.5a shall be promptly
submitted by the affected Lender to the Borrower in accordance with the
provisions hereof. Such certificate shall be prima facie evidence as to the
amount of such increased cost or reduced amount.

         (iii) Notwithstanding the foregoing provisions of this Section 2.5a,
the Borrower shall not be required to indemnify a Lender for the imposition by
the Agent of any federal income tax withholding in the event that such Lender
fails to complete, execute and deliver to the Agent a Withholding Certificate (a
defined under sec. 1.1441-1(c)(16) of the federal Income Tax Regulations).

2.5b  CAPITAL ADEQUACY. If, after the date hereof, (i) any adoption of or any
change in or in the interpretation of any Governmental Rule, or (ii) compliance
with any Governmental Rule of any Governmental Authority exercising control over
banks or financial institutions generally or any court of competent
jurisdiction, requires that the Commitment (including, without limitation,
obligations in respect of any Revolving Credit Loans, Bid Rate Loans, Swingline
Loans or Letters of Credit Outstanding) hereunder be treated as an asset or
otherwise be included for purposes of calculating the appropriate amount of
capital to be maintained by any Lender or any corporation controlling any Lender
(a "Capital Adequacy Event"), the result of which is to reduce the rate of
return on a Lender's capital as a consequence of its Commitment to a level below
that which the affected Lender could have achieved but for such Capital Adequacy
Event, taking into consideration the Lender's policies with respect to capital
adequacy, by an amount which the affected Lender reasonably deems to be
material, the affected Lender shall promptly deliver to the Borrower a statement
of the amount necessary to compensate the affected Lender or the reduction in
the rate of return on its capital attributable to its Commitment (the "Capital
Compensation Amount"). The affected Lender shall determine the Capital
Compensation Amount in good faith, using reasonable attribution and averaging
methods. Each affected Lender shall from time to time notify the Borrower of the
amount so determined. Each such notification shall be prima facie evidence of
the amount of the Capital Compensation Amount set forth therein, and such
Capital Compensation Amount shall be due and payable by the Borrower to the
affected Lender thirty (30) days after such notice is given. As soon as
practicable after any Capital Adequacy Event, the affected Lender shall submit
to the Borrower estimates of the Capital Compensation Amounts that would be
payable as a function of the affected Lender's Commitment hereunder.
Notwithstanding the foregoing, however, no Lender shall demand Capital
Compensation Amounts hereunder unless it is demanding similar compensation from
other borrowers who are similarly situated and who have a similar relationship
with such Lender and from which such Lender has the right to demand such
compensation.

2.5c  LIBOR UNASCERTAINABLE. If, on any date on which the Adjusted Long Term
Revolving Credit LIBOR, the Adjusted Short Term Revolving Credit LIBOR or the
Adjusted Term Loan LIBOR would otherwise be set, the Agent reasonably shall have
determined (which determination shall be final and conclusive) that by reason of
circumstances affecting the

                                     - 42 -
<PAGE>

interbank Eurodollar market, adequate and reasonable means do not exist for
ascertaining the LIBOR, the Agent shall give prompt notice of such determination
to the Borrower and the Lenders and, until the Agent notifies the Borrower and
the Lenders that the circumstances giving rise to such determination no longer
exist, the right of the Borrower to borrow under, convert to or renew the LIBOR
Option shall be suspended. Any notice of borrowing under, conversion to or
renewal of the LIBOR Option which was to become effective during the period of
such suspension shall be treated as a request to borrow under, convert to or
renew at the Base Rate Option with respect to the principal amount therein
specified.

2.5d  ILLEGALITY. If a Lender shall determine in good faith (which determination
shall be final and conclusive) that compliance by such Lender with any
applicable law, treaty or other Governmental Rule, (whether or not having the
force of law), or the interpretation or application thereof by any Governmental
Authority, has made it unlawful for such Lender to make or maintain the
Revolving Credit Loans or the Term Loans under the LIBOR Option or Bid Rate
Loans to which the Bid Rate Margin applies (including but not limited to
acquiring Eurodollar liabilities to fund such Loans), such Lender shall give
notice of such determination to the Borrower and the other Lenders.
Notwithstanding any provision of this Agreement to the contrary, unless and
until the affected Lender shall have given notice to the Borrower and the other
Lenders that the circumstances giving rise to such determination no longer
apply:

         (i) with respect to any Interest Periods thereafter commencing,
interest on the Revolving Credit Loans or Term Loans bearing interest at the
Adjusted Long Term Revolving Credit LIBOR, the Adjusted Short Term Revolving
Credit LIBOR or the Adjusted Term Loan LIBOR, as applicable, (in any such case
whichever one or more have been determined by the affected Lender to be
unlawful) shall, unless the Borrower shall have selected a different Option
which is then available, be computed and payable under the Base Rate Option; and

         (ii) on such date, if any, as shall be required by law, any Loans
bearing interest at the Adjusted Long Term Revolving Credit LIBOR, the Adjusted
Short Term Revolving Credit LIBOR, the Adjusted Term Loan LIBOR or any Bid Rate
Loan to which the Bid Rate Margin applies then outstanding shall be
automatically converted to the Base Rate Option, and the Borrower shall pay to
the affected Lender the accrued and unpaid interest on such Loans to (but not
including) the date of such conversion at the applicable interest rate or rates
in effect for such Loans prior to such conversion.

2.6   FEES.

2.6a  LONG TERM REVOLVING CREDIT FACILITY. The Borrower agrees to pay to the
Lenders, on a pro rata basis, beginning on March 31, 2002, and continuing
quarterly in arrears thereafter on the last day of each December, March, June

elapsed from and including the Closing Date to and including March 31, 2002, and
the last payment under this

                                     - 43 -

benefit of all of the Lenders a fee (the "Utilization Fee") (i) equal to 0.125%
per annum on the aggregate amount of the sum of all outstanding Revolving Credit
Loans, Bid Rate Loans, Swingline Loans, plus Letters of Credit Outstanding

days) for each date that the aggregate amount of the sum of all outstanding
Revolving Credit Loans, Bid Rate Loans, Swingline Loans, plus Letters of Credit

2.6d  AGENT'S FEE. The Borrower shall pay to the Agent for its own account the
Agent's Fee in the amounts and at such times as set forth in the Agent's Letter.
The Agent's Fee shall be retained by the Agent for its own account.

Section 2.13. The Facility Fees and the Utilization Fees shall be calculated on
the basis of a 360 day year and actual number of days elapsed. The calculation
of the amount of the Facility Fees due and owing to each Lender shall be made by
each Lender and shall be evidenced by posting such amount due under the Loan

2.8  EXTENSION OF SHORT TERM REVOLVING CREDIT TERMINATION DATE.

2.8a REQUESTS; APPROVAL BY ALL LENDERS OR SUPERMAJORITY LENDERS; OPTIONAL
CONVERSION TO TERM LOANS FOR NON-AGREEING LENDERS.

         (i) No earlier than forty-five (45) days and no later than thirty (30)
days prior to the then applicable Short Term Revolving Credit Termination Date,
the Borrower may request a 364-day extension of the Short Term Revolving Credit
Termination Date by written notice to the Agent. Agent shall promptly notify the
Lenders of such request. No later than twenty (20) days prior to the then
applicable Short Term Revolving Credit Termination Date, each Lender shall
respond to the Agent in writing as to whether or not it agrees to the Borrower's
request for such extension; provided, however, that the failure of any Lender to
respond with such time period shall not in any manner constitute an agreement by
such Lenders to extend the Short Term Revolving Credit Termination Date and
shall be deemed a notice of an election not to extend the then applicable Short
Term Revolving Credit Termination Date.

         (ii) If all Lenders elect in writing to extend the then applicable
Short Term Revolving Credit Termination Date, the Agent shall so notify the
Lenders and the Borrower promptly, that such Short Term Revolving Credit
Termination Date shall be extended for an additional period of 364 days.
Borrower hereby agrees to execute such amendments and modifications to the Loan
Documents, prior to the extension of the Short Term Revolving Credit Termination
Date, as Agent shall reasonably request to evidence and govern the extension of
such date.

                                     - 45 -
<PAGE>

         (iii) In the event that Lenders with at least seventy-five percent
(75%) of the Short Term Revolving Credit Commitments (the "Supermajority
Lenders"), but less than all of the Lenders, shall agree in writing to an
extension of the Short Term Revolving Credit Termination Date in accordance with
this Section 2.8a(iii), the Agent shall so notify the Lenders and the Borrower
promptly, but in no event earlier than twenty (20) days prior to the then
applicable Short Term Revolving Credit Termination Date, and: (i) the Short Term
Revolving Credit Commitments of those Lenders not agreeing in writing to an
extension of the Short Term Revolving Credit Termination Date (the "Non-Agreeing
Lenders") shall be terminated on the Short Term Revolving Credit Termination
Date (without giving effect to the extension thereof) and all Short Term
Revolving Credit Loans owing to the Non-Agreeing Lenders together with all
interest thereon and costs and expenses related thereto shall be due and payable
on such Short Term Revolving Credit Termination Date except to the extent that
(A) the Borrower shall substitute for such Non-Agreeing Lender another financial
institution pursuant to a duly executed Assignment and Assumption Agreement and
in accordance with the terms and conditions of Section 9.6 (except that such
financial institution may be assigned only the Short Term Revolving Credit Loan
and Short Term Revolving Credit Commitment of such Non-Agreeing Lender), or (B)
the Borrower has elected, by written notice received by the Agent no later than
ten (10) days prior to the Short Term Revolving Credit Termination Date, to
convert all or any portion of the Short Term Revolving Credit Loans of the
Non-Agreeing Lenders to Term Loans in accordance with Section 2.1Bg and, to the
extent that the less than the full aggregate amount of Short Term Revolving
Credit Loans of the Lender are to be so converted, then the Borrower shall
convert each and every Non-Agreeing Lender's Short Term Revolving Credit Loans
on a PRO RATA basis, (ii) the Short Term Revolving Credit Commitments of the
Lenders agreeing to an extension of the Short Term Revolving Credit Termination
Date (the "Agreeing Lenders") shall be extended for an additional period of 364
days, and (iii) none of the Agreeing Lenders shall be required to increase its
Short Term Revolving Credit Commitment. The Borrower hereby agrees to execute
such amendments and modifications to the Loan Documents, prior to any extension
of the Short Term Revolving Credit Termination Date, as Agent shall reasonably
request to evidence and govern the extension of such date and the Term Loans, if
any, arising under this Section 2.8.

2.8b  FAILURE OF SUPERMAJORITY LENDERS TO EXTEND; OPTIONAL CONVERSION TO TERM
LOAN. In the event that less than the Supermajority Lenders shall agree to an
extension of the Short Term Revolving Credit Termination Date in accordance with
Section 2.8a (iii), the Agent shall promptly so notify the Borrower and the
Lenders, the Short Revolving Credit Commitments shall be terminated on the Short
Term Revolving Credit Termination Date, and all Short Term Revolving Credit
Loans, together with all interest thereon and costs and expenses related
thereto, shall be due and payable on the Short Term Revolving Credit Termination
Date, unless the Borrower has elected, by written notice received by the Agent
no later than ten (10) days prior to the Short Term Revolving Credit Termination
Date (which notice Agent shall promptly forward to the Lenders), to convert all
or a portion of the Short Term Revolving Credit Loans outstanding on the Short
Term Revolving Credit Termination Date to Term Loans in accordance with Section
2.1Bg. Term Loans advanced pursuant to this Section 2.8b shall be allocated pro
rata among the Lenders based upon their respective Short Term Revolving Credit
Commitment Percentage. Any failure of the Agent or any Lender to notify any
party hereto that the Short Term Revolving

                                     - 46 -
<PAGE>

Credit Termination Date will not be extended shall not constitute a commitment
or agreement of any nature to extend such date.

2.9  SUBSTITUTION OR REPLACEMENT OF A LENDER. The Borrower shall have the right
(provided that at such time, no Event of Default and no Potential Default has
occurred and is continuing), in its sole discretion, to either:

         (i) repay, (A) at any time if either no Loans are outstanding or if
Loans bearing interest under the Base Rate Option are the only Loans
outstanding, (B) subject to Section 2.11, upon three (3) days prior notice if
the Loans outstanding include Revolving Credit Loans bearing interest under the
LIBOR Option, the Bid Rate Loans or the Swingline Loans, the outstanding Loans
of a Lender described in clause (x) or (y) of this Section 2.9 in whole,
together with interest thereon and any other amount due such a Lender pursuant
to the terms of this Agreement, and to terminate the Commitment of such a
Lender; or

         (ii) seek a substitute lending institution or institutions (which may
be one or more of the other Lenders) to purchase the Notes and assume the Loans,
the Commitment and the other obligations of such a Lender under this Agreement,

if any of the following conditions occur:

         (x) the obligation of a Lender to make Revolving Credit Loans which
bear or are to bear interest under the LIBOR Option has been suspended pursuant
to Subsection 2.5d; or

         (y) a Lender has responded negatively to a request for extension of the
Short Term Revolving Credit Termination Date pursuant to Section 2.8.

         Any proposed substitute lending institution, which is not a Lender
prior to the Borrower's selection thereof, must be acceptable to the Agent,
whose consent shall not be unreasonably withheld, and the existing Lenders shall
be given an option to increase these respective Commitments before any outside
lending institution may purchase the Notes and assume the Loans, Commitments and
other obligations of the Lender the subject of clauses (x) or (y) of this
Section 2.9.

2.10  LOAN REPAYMENT. Each repayment of the Loans shall be in the minimum amount
of $1,000,000, in the aggregate, or an integral multiple thereof (other than the
Swingline Loans which shall be in the minimum amount of $10,000 and the Bid Rate
Loans which shall be in the minimum amount of $5,000,000 or integral multiples
of $1,000,000 for amounts in excess of $5,000,000), or such lesser amount as is
actually outstanding thereunder. The Borrower, upon (i) oral or written notice
to Agent by 11:00 A.M. (eastern time) on the day of the proposed repayment, in
the case of Revolving Credit Loans or Term Loans bearing interest at the Base
Rate or the Swingline Loans or (ii) three (3) Business Days' prior oral or
written notice to the Agent, in the case of Bid Rate Loans or Revolving Credit
Loans or Term Loans bearing interest at the Adjusted Long Term Revolving Credit
LIBOR, the Adjusted Short Term Revolving Credit LIBOR or the Adjusted Term Loan
LIBOR, followed immediately thereafter by the Borrower's written confirmation to
the Agent of any oral notice, may repay the outstanding amount of the

                                     - 47 -
<PAGE>

Loans in whole or in part with accrued interest, fees, additional payments due
pursuant to Section 2.11 hereof, if any, and other amounts then due and payable
on the amount repaid to the date of such repayment. The Borrower may repay any
Portion of the Revolving Credit Loans bearing interest at the Base Rate or the
Swingline Loans without premium or penalty. All prepayments of the Bid Rate
Loans or Revolving Credit Loans or Term Loans bearing interest at the LIBOR
Option are subject to the terms of Section 2.11 hereof.

         In the event that principal payments are received on a day on which
principal payments are due on Revolving Credit Loans, Term Loans, Bid Rate Loans
and Swingline Loans the principal payments shall be applied: first, to repay in
full outstanding Swingline Loans, if any; second, to repay in full the principal
amount of the Revolving Credit Loans and Term Loans then due and payable, if
any; and third, to repay in full the principal amount of the Bid Rate Loans then
due and payable, if any.

         Any repayment of the Long Term Revolving Credit Loans shall increase,
by the amount of that repayment, the unborrowed balance of the Long Term
Revolving Credit Commitment; it being contemplated that the Borrower may repay
and reborrow from time-to-time under the Long Term Revolving Credit Commitment
until the Long Term Revolving Credit Termination Date. Any repayment of the
Short Term Revolving Credit Loans shall increase, by the amount of that
repayment, the unborrowed balance of the Short Term Revolving Credit Commitment;
it being contemplated that the Borrower may repay and reborrow from time-to-time
under the Short Term Revolving Credit Commitment until the Short Term Revolving
Credit Termination Date.

2.11  ADDITIONAL PAYMENTS BY THE BORROWER. If (i) the Borrower shall fail to
make any payment due hereunder on the due date thereof, (ii) the Borrower shall
make a payment, prepayment or conversion of any LIBOR Portion of the Revolving
Credit Loans or the Term Loans or any Bid Rate Loan on a day other than the last
day of the applicable Interest Period, (iii) the Borrower shall convert any
Portion to the Base Rate Option from another Option pursuant to Subsection 2.5d
on a day other than the last day of the relevant Interest Period, or (iv) the
Borrower shall fail on the date specified therefor to consummate any borrowing,
conversion or renewal after giving a request for a Disbursement or notice of
conversion or renewal or Notice of Bid Rate Borrowing, and, as a result of any
such action or inaction, a Lender reasonably incurs any losses and expenses
which it would not have incurred but for such action or inaction, the Borrower
shall pay such additional amounts as will compensate the affected Lender for
such losses and expenses, including the cost of reemployment of any funds
prepaid at rates lower than the cost to the affected Lender of such funds. Such
losses and expenses, which the affected Lender shall exercise reasonable efforts
to minimize, shall be specified in writing (setting forth, in reasonable detail,
the basis of calculation) to the Borrower by the affected Lender, which writing
shall be prima facie evidence of the amounts set forth therein, and such amounts
shall be payable within thirty (30) days of demand therefor.

2.12  VOLUNTARY REDUCTION OF AVAILABILITY. At any time and from time to time
upon no less than three (3) Business Days prior written notice to the Agent, the
Borrower may terminate, in whole or in part, without penalty, the then unused
portion of the Commitments, thereby causing a corresponding abatement of the
applicable Facility Fee. Each such reduction

                                     - 48 -

shall be in a minimum principal amount of $10,000,000 or in integral multiples
thereof. The applicable Facility Fee shall cease to accrue with respect to any
unused portion of the commitments so terminated on either (i) the date five (5)
Business Days after receipt of such notice or (ii) the date so designated in the
written notice if such written notice is given to the Agent more than five (5)
Business Days prior to the effective date of such termination. Notice of
termination once given shall be irrevocable and the portion of the Commitments
so terminated shall not be available for borrowing once such notice has been
given under the terms hereof. The Agent shall promptly notify each Lender of its
pro rata share of such terminated unused portion and the date of each such
termination. On the effective date for the reduction of the Long Term Revolving
Credit Commitment, the sum of (i) Letters of Credit Outstanding, PLUS (ii) Long
Term Revolving Credit Loans outstanding hereunder, PLUS (iii) Bid Rate Loans and
Swingline Loans outstanding hereunder and allocated to the Long Term Revolving
Credit Commitment may not exceed the Long Term Revolving Credit Commitment as so
reduced. On the effective date for the reduction of the Short Term Revolving
Credit Commitment, the sum of (i) the Short Term Revolving Credit Loans
outstanding hereunder, PLUS (ii) Bid Rate Loans and Swingline Loans outstanding
hereunder and allocated to the Short Term Revolving Credit Commitment may not
exceed the Short Term Revolving Credit Commitment as so reduced.

2.13  LOAN ACCOUNT. Each Lender and the Agent shall open and maintain on its
books a Loan Account in the name of the Borrower with respect to Disbursements
made, the Letters of Credit Outstanding, repayments, prepayments, conversion to
Term Loans, the computation and payment of interest and the Fees and the
computation of other amounts due and sums paid and payable to such Lender or
Agent pursuant to this Article II. Such Loan Account shall be prima facie
evidence as to the amount at any time due to such Lender or Agent from the
Borrower pursuant to this Article II; PROVIDED, however, that the failure of a
Lender to make notations, or to make accurate notations, on its Loan Account
including without limitation notations with respect to interest and Fees shall
not limit, expand or otherwise affect any obligations of the Borrower hereunder.

2.14  PAYMENT FROM ACCOUNTS MAINTAINED BY BORROWER. In the event that any
payment of principal, interest, Reimbursement Obligation, Letter of Credit
Borrowing, Fee or any other amount due to the Lenders or the Agent under the
Agreement, the Notes or the other Loan Documents is not paid when due, the Agent
is hereby authorized to effect such payment by debiting any demand deposit
account of the Borrower maintained with the Agent (excluding however any special
purpose fiduciary accounts, which are designated as such at the time of their
creation, and mandated by applicable statutes, regulations or rules) and
distributing such payment to the party to whom such amounts are due. This right
of debiting accounts of the Borrower is in addition to any right of set-off
accorded the Lenders or the Agent hereunder or by operation of law.

2.15  TIME, PLACE AND MANNER OF PAYMENTS. All payments to be made by the
Borrower under the Notes (other than those provided for in Sections 2.5 and 2.11
hereof), and of all fees and any other amounts due hereunder shall be made at
the principal office of the Agent. The Agent will promptly pay each such payment
received to each Lender or its order. All payments due a Lender by reason of
Sections 2.5 or 2.11 hereof shall be paid at the principal office of the Lender
which invoices the Borrower for such payment. All payments to be made by

                                     - 49 -
<PAGE>

the Borrower under this Agreement shall be paid in immediately available funds
no later than 12:00 Noon (eastern time) on the date such payment is due.
Notwithstanding anything herein to the contrary, (i) the Agent's Fee, (ii) the
Fronting Fee, and (iii) any interest paid with respect to any Loan or any
unreimbursed draw on the Letter of Credit to the extent a Lender has not been
required to honor or has not honored its funding obligation with respect thereto
shall be solely for the account of the Agent.

2.16   LETTER OF CREDIT SUB-FACILITY.

2.16a  ISSUANCE OF LETTERS OF CREDIT. The Borrower may request the issuance of
a letter of credit (each a "Letter of Credit") by delivering to the Agent a
completed application and agreement for letters of credit in such form as the
Agent may specify from time to time by no later than 10:00 A.M., Pittsburgh,
Pennsylvania time, at least five (5) business Days, or such shorter period as
may be agreed to by the Agent, in advance of the proposed date of issuance. Each
Letter of Credit shall be denominated in Dollars. Subject to the terms and
conditions hereof and in reliance on the agreements of the other Lenders set
forth in this Section 2.16, the Agent will issue a Letter of Credit provided
that each Letter of Credit shall (A) have a maximum maturity of one year from
the date of issuance, and (B) in no event expire later than ten (10) Business
Days prior to the Long Term Revolving Credit Termination Date and providing that
in no event shall the aggregate amount of Letters of Credit Outstanding exceed,
at any one time, $50,000,000. The amount of Letters of Credit Outstanding at any
time shall reduce the maximum amount otherwise available for Long Term Revolving
Credit Loans under the Long Term Revolving Credit Commitments. No Letters of
Credit may be issued hereunder to the extent that such issuance would cause the
sum of (i) the Letters of Credit Outstanding PLUS (ii) the aggregate amount of
Long Term Revolving Credit Loans outstanding to exceed the aggregate amount of
Long Term Revolving Credit Commitments then in effect.

2.16b  LETTER OF CREDIT FEES. The Borrower shall pay to the Agent for the
ratable account of the Lenders a fee (the "Letter of Credit Fee") equal to the
Applicable Long Term Revolving Credit LIBOR Margin for Long Term Revolving
Credit Loans (computed on the basis of a year of 360 days and actual days
elapsed), which fees shall be computed on the daily average amount of the
Letters of Credit Outstanding and shall be payable quarterly in arrears
commencing with the last Business Day of each March, June, September and
December following issuance of each Letter of Credit. The Borrower shall also
pay to the Agent for the Agent's sole account (i) one-eighth of one percent
(.125%) per annum of the amount of any Letters of Credit Outstanding (the
"Fronting Fee") quarterly in arrears, and (ii) as incurred the Agent's then
current customary fees and 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.

2.16c  LETTER OF CREDIT FEES UPON DEFAULT. (A) Upon the occurrence of an Event
of Default, and during the continuance of such Event of Default, upon notice
from the Agent (acting upon the instructions of the Required Lenders) to the
Borrower, or (B) upon the acceleration of the Bank Indebtedness for any reason
hereunder, the Letter of Credit Fee shall be

                                     - 50 -
<PAGE>

automatically increased by two hundred (200) basis points (2%) per annum in
excess of the applicable Letter of Credit Fee then in effect.

2.16d  DISBURSEMENTS, REIMBURSEMENT.

         (A) Immediately upon the issuance of each Letter of Credit, each Lender
shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from the Agent a participation in such Letter of Credit and each
drawing thereunder in an amount equal to such Lender's Long Term Revolving
Credit Commitment Percentage of the maximum amount available to be drawn under
such Letter of Credit and the amount of such drawing, respectively.

         (B) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, the Agent will promptly notify the
Borrower of the amount of such drawing and the date such payment shall be made.
The Borrower shall reimburse (such obligation to reimburse the Agent shall
sometimes be referred to as a "Reimbursement Obligation") the Agent for any
amount paid by the Agent under any Letter of Credit (each such date of a payment
by the Agent under a Letter of Credit, a "Drawing Date") in an amount equal to
the amount so paid by the Agent. If the Agent gives the Borrower notice of the
presentation of, and payment date of, a drawing under a Letter of Credit at or
before 11:00 A.M., Pittsburgh, Pennsylvania time, on the Drawing Date, such
Reimbursement Obligation shall be paid prior to 3:00 P.M., Pittsburgh,
Pennsylvania time, on such Drawing Date; and if the Agent gives the Borrower
notice of the presentation of, and payment date of, a drawing under a Letter of
Credit after 11:00 A.M., Pittsburgh, Pennsylvania time, on a Drawing Date, such
Reimbursement Obligation shall be paid prior to 12:00 noon, Pittsburgh,
Pennsylvania time, on the Business Day following the Drawing Date. In the event
the Borrower fails to reimburse the Agent for the full amount of any drawing
under any Letter of Credit by 12:00 noon, Pittsburgh, Pennsylvania time, on the
date the payment of such Reimbursement Obligation is due hereunder, the Agent
will promptly notify each Lender thereof, and the Borrower shall be deemed to
have requested that Long Term Revolving Credit Loans be made by the Lenders
under the Base Rate Option to be disbursed on the Drawing Date under such Letter
of Credit, subject to the amount of the unutilized portion of the Long Term
Revolving Credit Commitments (without giving effect to outstanding Letters of
Credit) and subject to the conditions set forth in Section 6.1 other than any
notice requirements. Any notice given by the Agent pursuant to this Subsection
2.16d(B) may be oral if immediately confirmed in writing; PROVIDED that the lack
of such an immediate confirmation shall not affect the conclusiveness or binding
effect of such notice.

         (C) Each Lender shall upon any notice pursuant to Subsection 2.16d(B)
make available to the Agent an amount in immediately available funds equal to
its Long Term Revolving Credit Commitment Percentage of the amount of the
drawing, whereupon the participating Lenders shall (subject to Subsection
2.16d(D)) each be deemed to have made a Long Term Revolving Credit Loan under
the Base Rate Option to the Borrower in that amount. If any Lender so notified
fails to make available to the Agent for the account of the Agent the amount of
such Lender's Long Term Revolving Credit Commitment Percentage of such amount by
no later than 2:00 P.M., Pittsburgh, Pennsylvania time on the Drawing Date, then
interest shall accrue on such Lender's obligation to make such payment, from the
Drawing Date to the date on which such Lender makes such payment (i) at a rate
per annum equal to the Federal Funds

                                     - 51 -
<PAGE>

Effective Rate during the first three days following the Drawing Date and (ii)
at a rate per annum equal to the rate applicable to Long Term Revolving Credit
Loans under the Base Rate Option on and after the fourth day following the
Drawing Date. The Agent will promptly give notice of the occurrence of the
Drawing Date to each Lender, but failure of the Agent to give any such notice on
the Drawing Date or in sufficient time to enable any Lender to effect such
payment on such date shall not relieve such Lender from its obligation under
this Subsection 2.16d(C).

         (D) With respect to any unreimbursed drawing that is not converted into
Long Term Revolving Credit Loans under the Base Rate Option to the Borrower in
whole or in part as contemplated by Subsection 2.16d(B), because of the timing
of notice to the Borrower of the applicable Reimbursement Obligation or the
Borrower's failure to satisfy the conditions set forth in Section 6.1 other than
any notice requirements or for any other reason, the Borrower shall be deemed to
have incurred from the Agent a Letter of Credit Borrowing in the amount of such
drawing. Such Letter of Credit Borrowing shall be due and payable on demand
(together with interest) and shall bear interest at the rate per annum
applicable to the Long Term Revolving Credit Loans under the Base Rate Option as
adjusted to reflect the default rate provisions set forth in Subsection 2.4f.
Each Lender's payment to the Agent pursuant to Subsection 2.16d(C) shall be
deemed to be a payment in respect of its participation in such Letter of Credit
Borrowing and shall constitute an LC Participation Advance from such Lender in
satisfaction of its participation obligation under this Subsection 2.16d. The
provisions of this Subsection (D) are solely for the benefit of the Agent, as
issuer of the Letters of Credit, and shall not be deemed to excuse, waive or
consent to an Event of Default under Section 7.1 arising from an unreimbursed
drawing giving rise to an LC Participation Advance.

2.16e  REPAYMENT OF LC PARTICIPATION ADVANCES.

         (A) Upon (and only upon) receipt by the Agent for its account of
immediately available funds from the Borrower (i) in reimbursement of any
payment made by the Agent under the Letter of Credit with respect to which any
Lender has made a LC Participation Advance to the Agent, or (ii) in payment of
interest on such a payment made by the Agent under such a Letter of Credit, the
Agent will pay to each Lender, in the same funds as those received by the Agent,
the amount of such Bank's Long Term Revolving Credit Commitment Percentage of
such funds, except the Agent shall retain the amount of the Long Term Revolving
Credit Commitment Percentage of such funds of any Lender that did not make an LC
Participation Advance in respect of such payment by Agent.

         (B) If the Agent is required at any time to return to the Borrower, or
to a trustee, receiver, liquidator, custodian, or any official in any proceeding
described in Section 7.3, any portion of the payments made by the Borrower to
the Agent pursuant to Subsection 2.16d(B) in reimbursement of a payment made
under the Letter of Credit or interest or fee thereon, each Lender shall, on
demand of the Agent, forthwith return to the Agent the amount of its Long Term
Revolving Credit Commitment Percentage of any amounts so returned by the Agent
plus interest thereon from the date such demand is made to the date such amounts
are returned by such Lender to the Agent, at a rate per annum equal to the
Federal Funds Effective Rate in effect from time to time.

                                     - 52 -
<PAGE>

2.16f  DOCUMENTATION. The Borrower agrees to be bound by the terms of the
Agent's application and agreement for letters of credit and the Agent's written
regulations and customary practices relating to letters of credit, though such
interpretation may be different from the Borrower's own. In the event of a
conflict between such application or agreement and this Agreement, this
Agreement shall govern. It is understood and agreed that, except in the case of
gross negligence or willful misconduct, the Agent shall not be liable for any
error and/or mistakes, whether of omission or commission, in following the
Borrower's instructions or those contained in the Letters of Credit or any
modifications, amendments or supplements thereto.

2.16g  DETERMINATIONS TO HONOR DRAWING REQUESTS. In determining whether to honor
any request for drawing under any Letter of Credit by the beneficiary thereof,
the Agent shall be responsible only to determine that the documents and
certificates required to be delivered under such Letter of Credit have been
delivered and that they comply on their face with the requirements of such
Letter of Credit.

2.16h  NATURE OF PARTICIPATION AND REIMBURSEMENT OBLIGATIONS. Each Lender's
obligation in accordance with this Agreement to make the Long Term Revolving
Credit Loans or Participation Advances, as contemplated by Subsection 2.16d, as
a result of a drawing under an LC Letter of Credit, and the obligation of the
Borrower to reimburse the Agent upon a draw under a Letter of Credit, shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Section 2.16 under all circumstances,
including the following circumstances:

                  (i) any set-off, counterclaim, recoupment, defense or other
         right which such Lender may have against the Agent, the Borrower or any
         other Person for any reason whatsoever;

                  (ii) the failure of the Borrower or any other Person to
         comply, in connection with a Letter of Credit Borrowing, with the
         conditions set forth in this Agreement for the making of a Long Term
         Revolving Credit Loan, it being acknowledged that such conditions are
         not required for the making of a Letter of Credit Borrowing and the
         obligation of the Lenders to make LC Participation Advances under
         Subsection 2.16d; provided, however the aggregate amount thereof shall
         in no event exceed the unutilized Long Term Revolving Credit
         Commitments;

                  (iii) any lack of validity or enforceability of any Letter of
         Credit;

                  (iv) the existence of any claim, set-off, defense or other
         right which the Borrower or any Lender may have at any time against a
         beneficiary or any transferee of any Letter of Credit (or any Persons
         for whom any such transferee may be acting), the Agent or any Lender or
         any other Person or, whether in connection with this Agreement, the
         transactions contemplated herein or any unrelated transaction
         (including any underlying transaction between the Borrower and the
         beneficiary for which any Letter of Credit was procured);

                                     - 53 -
<PAGE>

                  (v) any draft, demand, certificate or other document presented
         under any Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect even if the Agent has been notified thereof;

                  (vi) payment by the Agent under any Letter of Credit against
         presentation of a demand, draft or certificate or other document which
         does not comply with the terms of such Letter of Credit;

                  (vii) any adverse change in the business, operations,
         properties, assets, condition (financial or otherwise) or prospects of
         the Borrower;

                  (viii) any breach of this Agreement or any other Loan Document
         by any party thereto;

                  (ix) the occurrence or continuance of any proceeding described
         in Section 7.3 with respect to the Borrower;

                  (x) the fact that an Event of Default shall have occurred and
         be continuing;

                  (xi) the fact that the Long Term Revolving Credit Termination
         Date shall have passed or this Agreement or the Long Term Revolving
         Credit Commitments hereunder shall have been terminated; and

                  (xii) any other circumstance or happening whatsoever, whether
         or not similar to any of the foregoing.

2.16i  INDEMNITY. In addition to amounts payable as provided in Section 9.15,
the Borrower hereby agrees to protect, indemnify, pay and save harmless the
Agent from and against any and all claims, demands, liabilities, damages,
losses, costs, charges and expenses (including reasonable fees, expenses and
disbursements of counsel and allocated costs of internal counsel) which the
Agent may incur or be subject to as a consequence, direct or indirect, of (i)
the issuance of any Letter of Credit, other than as a result of (A) gross
negligence or willful misconduct of the Agent as determined by a final judgment
of a court of competent jurisdiction or (B) subject to the following clause
(ii), the wrongful dishonor by the Agent of a proper demand for payment made
under any Letter of Credit, or (ii) the failure of the Agent to honor a drawing
under any such Letter of Credit as a result of any act or omission, whether
rightful or wrongful, of any present or future de jure or de facto Governmental
Authority (all such acts or omissions herein called "Governmental Acts").

2.16j  LIABILITY FOR ACTS AND OMISSIONS. As between the Borrower and the Agent,
the Borrower assumes all risks of the acts and omission of, or misuse of the
Letters of Credit by, the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, the Agent shall not be
responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or
legal effect of any document submitted by any party in connection with the
application for an issuance of any such Letter of Credit, even if it should in
fact prove to be in

                                     - 54 -
<PAGE>

any or all respects invalid, insufficient, inaccurate, fraudulent or forged;
(ii) the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) the failure of the beneficiary
of any such Letter of Credit, or any other party to which such Letter of Credit
may be transferred, to comply fully with any conditions required in order to
draw upon such Letter of Credit so long as the documents presented in connection
with such draw appear on their face to substantially comply with the terms and
conditions of the relevant Letter of Credit; (iv) any claim of the Borrower
against any beneficiary of any such Letter of Credit, or any transferee of such
Letter of Credit, or any dispute between or among the Borrower and any
beneficiary of any Letter of Credit or any such transferee; (v) errors,
omissions, interruptions or delays in transmission or delivery of any messages,
by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher;
(vi) errors in interpretation of technical terms; (vii) any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any such Letter of Credit or of the proceeds thereof; (viii) the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing under such Letter of Credit; or (ix) any consequences arising
from causes beyond the control of the Agent, including any Governmental Acts,
and none of the above shall affect or impair, or prevent the vesting of, any of
the Agent's rights or powers hereunder. Nothing in the preceding sentence shall
relieve the Agent from liability for the Agent's gross negligence or willful
misconduct in connection with actions or omissions described in such clauses (i)
through (viii) of such sentence.

2.16k  UNIFORM CUSTOMS. Except and to the extent inconsistent with the specific
provisions hereof, this Agreement, each Letter of Credit hereunder and all
transactions in connection therewith shall be interpreted, construed and
enforced according to: (i) the "Uniform Customs and Practice for Documentary
Credits" (1993 Revision), International Chamber of Commerce Publication No. 500
or the "International Standby Practices 1998", International Chamber of Commerce
Publication No. 590, as applicable, and in each case subsequent revisions

extent not prohibited by applicable law and (ii) the laws of the jurisdiction in
which the office of the Agent is located for purposes of issuing Letters of
Credit hereunder including, without limitation, the Uniform Commercial Code, and
excluding conflict of laws rules.

2.16l  CONDITIONS PRECEDENT TO ISSUANCE OF LETTERS OF CREDIT. The obligation of
the Agent to issue, or amend, any Letters of Credit hereunder is subject to the
satisfaction of each of the following conditions precedent:

                  (i) The Borrower shall have performed and complied, in all
         material respects, with all agreements and conditions herein required

         Default shall exist.

                  (ii) The representations and warranties contained in Article
         III hereof shall be correct in all material respects (A) when made and
         (B) at the time of each issuance of, or amendment of, a Letter of

                                     - 55 -
<PAGE>

         relate solely to an earlier date (in which case such representations
         and warranties shall have been true and correct in all material
         respects as of such date); PROVIDED, however, that for purposes of
         clause (B) of this Subsection 2.16l, the representations and warranties
         contained in Section 3.6 shall be deemed updated if, and to the extent
         that, an action, suit, investigation, litigation or governmental
         investigation is set forth in any Form 10-K or 10-Q filed by the
         Borrower in respect of any period subsequent to the date hereof or in

set forth in clause (i) and (ii) of this Subsections 2.16l are true and correct.

ARTICLE III.   REPRESENTATIONS AND WARRANTIES.

               To induce the Lenders and the Agent to enter into this Agreement
and to make the Loans and issue the Letters of Credit herein provided for, the
Borrower warrants to the Lenders and the Agent that:

3.1  CORPORATE EXISTENCE. The Borrower and each of its Significant Subsidiaries
is a corporation duly organized, validly existing and in good standing under the
laws of its respective state of incorporation and it is duly qualified and in
good standing as a foreign corporation authorized to do business in each
jurisdiction where, because of the nature of its respective properties or
businesses, such qualification is required or, if not so qualified or in good
standing in any state, the lack of such qualification or good standing will not
materially affect the Agent's or the Lender's ability to enforce this Agreement,
the Notes or the other Loan Documents or will not have a Material Adverse Effect
on the Borrower's or such Subsidiary's ability to carry on its business or the
Borrower's ability to comply with this Agreement, the Notes or the other Loan
Documents.

3.2  CORPORATE AUTHORITY. The Borrower is duly authorized to execute and deliver
this Agreement, the Notes and the other Loan Documents to which it is or will
become a party; all necessary corporate action to authorize the execution and
delivery of this Agreement, the Notes and the other Loan Documents to which it
is or will become a party has been properly taken; and it is and will continue
to be duly authorized to borrow hereunder and to perform all of the other terms
and provisions of this Agreement, the Notes and the other Loan Documents to
which it is or will become a party.

3.3  ENFORCEABILITY. This Agreement and the Notes have each been, and each other
Loan Document to which it will become a party will be, duly and validly executed
and delivered by the Borrower and each constitutes or will constitute a valid
and legally binding agreement of the Borrower enforceable in accordance with its
terms.

                                     - 56 -
<PAGE>

3.4  NO RESTRICTIONS. Neither the execution and delivery of this Agreement, the
Notes and the other Loan Documents to which it is or will become a party, the
consummation of the transactions herein contemplated nor compliance with the
terms and provisions hereof or of the Notes, will conflict with or result in a
breach of any of the terms, conditions or provisions of the certificate of
incorporation or the by-laws of the Borrower or of any law or of any regulation,
order, writ, injunction or decree of any court or governmental agency or of any
agreement, indenture or other instrument to which the Borrower or any
Significant Subsidiary is a party or by which any of them is bound or to which
it is subject, or constitute a default thereunder or result in the creation or
imposition of any Encumbrance of any nature whatsoever upon any of the property
or assets of the Borrower pursuant to the terms of any agreement, indenture or
other instrument, except those restrictions which, individually or in the
aggregate, would not have a Material Adverse Effect upon the Borrower and its
Consolidated Subsidiaries taken as a whole.

3.5  FINANCIAL STATEMENTS. The Borrower has furnished to the Lenders and the
Agent the consolidated balance sheets and the related consolidated statements of
income, shareholders' equity and changes in financial position of the Borrower
as at Borrower's Fiscal Year ending December 31, 2000 and for its Fiscal Quarter
ending September 30, 2001. All such financial statements, including the related
notes, have been prepared in accordance with GAAP, except as expressly noted
therein, and fairly present the consolidated financial position of the Borrower
as at the dates thereof and the results and consolidated results of the
operations and the changes in the financial position of the Borrower and its
Consolidated Subsidiaries. Other than the Bank Indebtedness there were no
material liabilities of the Borrower and its Consolidated Subsidiaries, taken as
a whole, contingent or otherwise, not reflected in such financial statements.

3.6  ABSENCE OF LITIGATION. Except as set forth in the Forms 10-K, 10-Q, or 8-K
most recently filed by the Borrower as of the Closing Date, respectively, there
are no actions, suits, investigations, litigation or governmental proceedings
pending or, to the Borrower's knowledge, threatened against the Borrower or any
Consolidated Subsidiary or any of their respective properties, which would have
a Material Adverse Effect on the Borrower and the Consolidated Subsidiaries

7.11  CONSEQUENCES OF AN EVENT OF DEFAULT. If one or more of the Events of
Default occur then (a) if such Event of Default is set forth in Sections 7.3 or
7.4, the Commitments shall automatically terminate and the Bank Indebtedness
then outstanding shall become immediately due and payable, without necessity of
demand, presentation, protest, notice of dishonor or notice of default; or (b)
if such Event of Default is set forth in any of the remaining Sections of this
Article VII, then the Agent, at the request of the Required Lenders, and without
notice to the Borrower, shall declare the Borrower in default hereunder, and
upon such declaration, shall, at the request of the Required Lenders, terminate
the Commitment and/or declare the Bank Indebtedness then outstanding immediately
due and payable, without necessity of any further demand, presentation, protest,
notice of dishonor or further notice of default, whereupon such Bank
Indebtedness shall be immediately due and payable.

7.12  REMEDIES UPON DEFAULT. Upon the termination of the Commitments and
acceleration of the Notes following the occurrence of an Event of Default, the
Lenders shall, unless such termination and acceleration subsequently have been
rescinded, have the full panoply of rights and remedies granted to them under
this Agreement and all those rights and remedies granted by law to creditors,
and the Agent, at the direction of the Required Lenders, shall proceed to
protect and enforce the Lenders' rights by an action at law, suit in equity or
other appropriate proceeding, whether for the specific performance of any
agreement contained herein, in the Notes or in any of the other Loan Documents,
or for an injunction against a violation of any of the terms hereof or thereof,
or in aid of the exercise of any power granted hereby or thereby or by law. No
right, power or remedy conferred by this Agreement, in the Notes, or by any
other Loan Document, upon the Agent or the Lenders shall be exclusive of any
other right, power or remedy referred to herein or therein or now or hereafter
available at law, in equity, by statute or otherwise. No exercise of any one
right or remedy shall be deemed a waiver of other rights or remedies. The rights
and remedies of the Agent and the Lenders specified herein are for the sole and
exclusive benefit, use and protection of the Agent and the Lenders, and the
Agent and the Lenders shall be entitled, but shall have no duty or obligation,
to exercise or to refrain from exercising any right or remedy reserved to the
Agent or the Lenders hereunder.

7.13  CASH COLLATERAL. Upon the occurrence of any Event of Default or upon the
declaration by the Required Lenders of any other Event of Default and the
termination of the Commitments, the obligation of the Agent to issue or amend
Letters of Credit shall terminate, and, in addition to the other amounts payable
hereunder with respect to Letters of Credit, an amount equal to the maximum
amount which may at any time be drawn under the Letters of Credit then
outstanding (whether or not any beneficiary of such Letters of Credit shall have
presented, or shall be entitled at such time to present, the drafts or other
documents required to draw under such Letters of Credit) shall automatically
become immediately due and payable, without presentment, demand, protest or
other requirements of any kind, all of which are hereby expressly waived by the
Borrower; PROVIDED that the foregoing shall not affect in any way the
obligations of the Lenders to purchase from the Agent participations in the
unreimbursed amount of any drawings under the Letters of Credit issued by it as
provided in Subsection 2.16d. So long as the Letters of Credit shall remain
outstanding, any amounts declared due pursuant to this Section with respect to
the outstanding Letters of Credit when received by the Agent shall be deposited
and held by the Agent in an interest bearing account denominated in the name of
the Agent for the benefit of the Agent and the Lenders over which the Agent
shall have sole

                                     - 70 -
<PAGE>

dominion and control of withdrawals (the "Cash Collateral Account") as cash
collateral for the obligation of the Borrower to reimburse the Agent in the
event of any drawing under the Letters of Credit and upon any drawing under such
Letters of Credit in respect of which the Agent has deposited in the Cash
Collateral Account any amounts declared due pursuant to this Section, the Agent
shall apply such amounts held by the Agent to reimburse the Agent for the amount
of such drawing. In the event that any Letter of Credit in respect of which the
Agent has deposited in the Cash Collateral Account any amounts described above
is cancelled or expires or in the event of any reduction in the maximum amount
available at any time for drawing under any of the Letters of Credit
outstanding, the Agent shall apply the amount then in the Cash Collateral
Account designated to reimburse the Agent for any drawings under the Letters of
Credit issued by it less the maximum amount available at any time for drawing
under the Letters of Credit remaining outstanding immediately after such
cancellation, expiration or reduction, if any, to the payment in full of the
outstanding Bank Indebtedness, and second, to the payment of any excess, to the
Borrower.

require the sharing among the Lenders of collections specifically relating to,
or of the proceeds of any collateral securing, any other Indebtedness of the
Borrower to any Lender.

8.9   SUCCESSOR AGENT.

Lenders have not appointed such a successor, the Agent shall use reasonable
commercial efforts to procure a successor reasonably satisfactory to the Lenders
and the Borrower, to serve as agent for the Lenders hereunder and under the

powers and duties of the Agent.

"Syndication Agent" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Each Lender acknowledges that it has not relied, and will not
rely, on any of the Lenders identified as Syndication Agents in deciding to
enter into this Agreement or in taking action hereunder.

Lenders and the Agent shall be restored to their former positions and rights,
and any Event of Default waived shall be deemed to be cured and not continuing,
but no such waiver shall extend to any subsequent or other Event of Default, or
impair any right consequent thereon.

         (f) In the case of a Website Posting, upon delivery of a Notice of such
posting (including the information necessary to access such site) by another
means set forth in this Section 9.3, and

         (g) If given by any other means (including by overnight courier), when
actually received. Any Lender giving a Notice to the Borrower shall concurrently
send a copy thereof to the Agent, and the Agent shall promptly notify the other
Lenders of its receipt of such Notice.

              All such notices shall be effective three (3) days after mailing,
the date of electronic transmission or when received, whichever is earlier. The
Borrower, the Lenders and the Agent may each change the address for service of
notice upon it by a notice in writing to the other parties hereto.

9.4   TAX WITHHOLDING. Each Lender or assignee or participant of a Lender that
is not incorporated under the Laws of the United States of America or a state
thereof (and, upon the written request of the Agent, each other Lender or
assignee or participant of a Lender) agrees that it will deliver to each of the
Borrower and the Agent two (2) duly completed appropriate valid Withholding
Certificates (as defined under sec. 1.1441-1(c)(16) of the Income Tax
Regulations ("Regulations")) certifying its status (i.e., U.S. or foreign
person) and, if appropriate, making a claim of reduced, or exemption from
withholding tax on the basis of an income tax treaty or an exemption provided by
the Internal Revenue Code. Such delivery may be made by electronic transmission
as described in sec. 1.1441-1(e)(4)(iv) of the Regulations if the Agent
establishes an electronic delivery system. The term "Withholding Certificate"
means a Form W-9; a Form W-8BEN; a Form W-8ECI; a Form W-8IMY and the related
statements and certifications as required under sec. 1.1441-1(e)(3) of the
Regulations; a statement described in sec. 1.871-14(c)(2)(v) of the Regulations;
or any other certificates under the Code or Regulations that certify or
establish the status of a payee or beneficial owner as a U.S. or foreign person.
Each Lender, assignee or participant required to deliver to the Borrower and the
Agent a valid Withholding Certificate pursuant to the preceding sentences shall
deliver such valid Withholding Certificate as follows: (A) each Lender which is
a party hereto on the Closing Date shall deliver such valid Withholding
Certificate at least five (5) Business Days prior to the first date on which any
interest or fees are payable by the Borrower hereunder for the account of such
Lender; and (B) each assignee or participant shall deliver such valid
Withholding Certificate at least five (5) Business Days before the effective
date of such assignment or participation (unless the Agent in its sole
discretion shall permit such assignee or participant to deliver such Withholding
Certificate less than five (5) Business Days before such date in which case it
shall be due on the

                                     - 77 -
<PAGE>

date specified by the Agent). Each Lender, assignee or participant which so
delivers a valid Withholding Certificate further undertakes to deliver to each
of the Borrower and the Agent two (2) additional copies of such Withholding
Certificate (or a successor form) on or before the date that such Withholding
Certificate expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent Withholding Certificate so delivered by
it, and such amendments thereto or extensions or renewals thereof as may be
reasonably requested by the Borrower or the Agent. Notwithstanding the
submission of a Withholding Certificate claiming a reduced rate of, or exemption
from, U.S. withholding tax, the Agent shall be entitled to withhold United
States federal income taxes at the full 30% withholding rate if in its
reasonable judgment it is required to do so under the due diligence requirements
imposed upon a withholding agent under sec. 1.1441-7(b) of the Regulations.
Further, the Agent is indemnified under sec. 2.1461-1(e) of the Regulations
against any claims and demands of any Lender or assignee or participant of a
Lender for the amount of any tax it deducts and withholds in accordance with
regulations under sec. 1441 of the Internal Revenue Code.

9.5  SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the Borrower,
the Agent and the Lenders and their respective successors and assigns, and shall
inure to the benefit of the Borrower, the Agent and the Lender and the
successors and assigns of the Agent and the Lender.

9.6  ASSIGNMENTS AND PARTICIPATIONS.

9.6a ASSIGNMENTS. Subject to the remaining provisions of this Subsection 9.6a,
any Lender (a "Transferor Lender"), at any time, in the ordinary course of its
commercial banking business and in accordance with applicable law, may sell to
one or more financial institutions (individually a "Purchasing Lender"), a
portion or all of its rights and obligations under this Agreement and the Notes
then held by it, pursuant to an Assignment and Assumption Agreement
substantially in the form of Exhibit "J" executed by the Transferor Lender, such
Purchasing Lender and the Agent; subject, however to the following requirements:

              (i) Each such assignment must be in a minimum amount of
$5,000,000, or, if in excess thereof, in integral multiples of $1,000,000,
unless such Lender's Commitment is less than $5,000,000, in which case such
assignment shall be in the full amount of such Lender's Commitment;

              (ii) During the first ninety (90) days following the Closing Date,
each assignment made shall become effective only on a date which coincides with
the expiration date of any LIBOR Interest Period then in effect, unless the
Agent agrees to waive this provision;

              (iii) The Borrower and the Agent shall consent to each such
assignment, which consent shall not be unreasonably withheld (provided, that the
Borrower shall not be deemed to have unreasonably withheld its consent if the
proposed assignee is a "foreign person" as defined in sec. 1.1441-1(c)(2) of the
Regulations); and

              (iv) The Transferor Lender shall pay to the Agent a $3,500 service
fee for each such transfer at the time of each such transfer;

                                     - 78 -
<PAGE>

PROVIDED, however (x) the restrictions set forth in items (i) and (iii) above
shall not apply in the case of an assignment by a Lender to an Affiliate of such
Lender (other than an Affiliate of such Lender which is also a "foreign person"
as defined in sec. 1.1441-1(c)(2) of the Regulations) and (y) the restriction
set forth in item (i) above shall not apply in the case of any assignment by any
Transferor Lender upon the occurrence and during the continuation of an Event of
Default; and PROVIDED FURTHER, that upon the occurrence and during the
continuance of an Event of Default the consent of the Borrower to any assignment
is not required.

         Upon the execution, delivery, acceptance and recording of any such
Assignment and Assumption Agreement, from and after the Transfer Effective Date
determined pursuant to such Assignment and Assumption Agreement, all parties
hereto agree that (a) the Purchasing Lender thereunder shall be a party hereto
as a Lender and, to the extent provided in such Assignment and Assumption
Agreement, shall have the rights and obligations of a Lender hereunder with a
Commitment as set forth therein, and (b) the Transferor Lender thereunder shall,
to the extent provided in such Assignment and Assumption Agreement, be released
from its obligations as a Lender under this Agreement. Such Assignment and
Assumption Agreement shall be deemed to amend this Agreement (without further
action) to the extent, and only to the extent, necessary to reflect the addition
of such Purchasing Lender as a Lender and the resulting adjustment of Commitment
Percentages arising from the purchase by such Purchasing Lender of all or a
portion of the rights and obligations of such Transferor Lender under this
Agreement and its Notes. On or prior to the Transfer Effective Date, the
Borrower shall execute and deliver to the Agent, in exchange for the surrendered
Notes held new Notes to the order of such Purchasing Lender in an amount equal
to the Commitment or the Loans assumed by it and purchased by it pursuant to
such Assignment and Assumption Agreement, and new Notes to the order of the
Transferor Lender in an amount equal to the Commitment or the Loans retained by
it hereunder.

         In addition to the assignments permitted above, any Lender may assign
and pledge all or any portion of its Loans and Notes to any Federal Reserve Bank
as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank. No such assignment shall release the assigning Lender from its obligations
and duties hereunder.

9.6b  ASSIGNMENT REGISTER. The Agent shall maintain, at its address referred to
in Subsection 9.3b, a copy of each Assignment and Assumption Agreement delivered
to it and a register (the "Register") for the recordation of the names and
addresses of the Lenders and the amount of the Loans owing to each Lender from
time to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrower, the Agent and the Lenders may treat each
Person whose name is recorded in the Register as the owner of the Loans recorded
therein for all purposes of this Agreement. The Register shall be available at
the office of the Agent set forth in Subsection 9.3b for inspection by either
Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

9.6c  PARTICIPATIONS. Each Lender, in the ordinary course of its commercial
banking business and in accordance with applicable law, may sell to one or more
Participants a participating interest in any Loan owing to such Lender, the
interest of such Lender in any Notes

                                     - 79 -
<PAGE>

or any Letters of Credit Outstanding or the Commitment of such Lender. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of its Notes
for all purposes under this Agreement and the Borrower, the other Lenders and
the Agent shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement or its
Notes and the Participants shall have voting rights only with respect to matters
described in items (B), (C), (D), (E) and (F) of Section 9.1. Each Lender agrees
to promptly notify the Agent of the sale of each participating interest in the
Loans and Commitments.

9.6d  TAX WITHHOLDING COMPLIANCE. 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 9.4 relating to federal income tax withholding.

9.7   SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining portions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

9.8   SURVIVAL. All representations, warranties, covenants and agreements of the
Borrower contained herein in the Notes or in the other Loan Documents or made in
writing in connection herewith or therewith shall survive the issuance of the
Notes and the Letters of Credit and shall continue in full force and effect so
long as the Borrower may borrow hereunder and so long thereafter until payment
in full of all the Notes and the Bank Indebtedness.

9.9   GOVERNING LAW. This Agreement, each Note and each other Loan Document
shall be a contract made under, governed by and construed in accordance with the
laws of the Commonwealth of Pennsylvania without reference to the provision
thereof regarding conflicts of law except where such law is superseded by
applicable Federal law.

9.10  NON-BUSINESS DAYS. Except as otherwise specifically required pursuant to
the terms of this Agreement, whenever any payment hereunder or under the Notes
is due and payable on a day which is not a Business Day, such payment may be
made on the next succeeding Business Day.

9.11  INTEGRATION. This Agreement constitutes the entire agreement between the
parties relating to this financing transaction and it supersedes all prior
understandings and agreements, whether written or oral, between the parties
hereto concerning the subject matter of this Agreement.

9.12  SET-OFF. The Borrower hereby gives to the Lenders a lien and security
interest for the amount of any Bank Indebtedness upon and in any property,
credits, securities or money of the Borrower which may at any time be delivered
to, or be in the possession of, or owed by any Lender in any capacity whatever,
including the balance of any deposit account but excluding any

                                     - 80 -
<PAGE>

trust or fiduciary accounts, in each case maintained by the Borrower with such
Lender. The Borrower hereby authorizes each Lender in case of an Event of
Default, at such Lender's option, at any time and from time to time, to apply,
at the discretion of such Lender, to the payment of Bank Indebtedness, any and
all such property, credits, securities or money now or hereafter in the hands of
such Lender belonging or owed to the Borrower. Nothing herein shall restrict any
Lender's ability to set off any property, credits, securities or money of the
Borrower which may at any time be delivered to, or be in possession or owed to
any Lender in any capacity whatever to satisfy an independent obligation of the
Borrower to the Lender.

9.13  FORUM. The parties hereto agree that any action or proceeding arising out
of or relating to this Agreement, the Notes or the other Loan Documents shall be
commenced only in the Court of Common Pleas of Allegheny County, Pennsylvania,
or in the District Court of the United States for the Western District of
Pennsylvania and each party agrees that a summons and complaint commencing an
action or proceeding in either of such courts shall be properly served and shall
confer personal jurisdiction if served personally or by certified mail to the
party at its respective address set forth in Section 9.3, or as otherwise
provided under the laws of the Commonwealth of Pennsylvania. Further, the
parties hereby specifically consent to the personal jurisdiction of the Court of
Common Pleas of Allegheny County, Pennsylvania, and the District Court of the
United States for the Western District of Pennsylvania, and waive and hereby
acknowledge that the parties are estopped from raising any claim that any such
court lacks personal jurisdiction over such party so as to prohibit either such
court from adjudicating any issues raised in a complaint filed with any such
court against the Borrower or the Lenders concerning this Agreement.

9.14  WAIVER OF JURY TRIAL. Each of the Agent, the Lenders and the Borrower
hereby knowingly, voluntarily and intentionally waive any rights they may have
to a trial by jury in respect of any litigation based hereon, or arising out of,
under, or in connection with, this Agreement or any other Loan Document, or any
course of conduct, course of dealing, statements (whether verbal or written) or
actions of the Agent, the Lenders or the Borrower relating hereto or thereto.
The Borrower acknowledges and agrees that it has received full and sufficient
consideration for this provision (and each other provision of each other Loan
Document to which it is a party) and that this provision is a material
inducement for the Lenders to enter into this Agreement and each such other Loan
Document.

9.15  INDEMNITY. The Borrower hereby agrees to indemnify the Agent, the
Syndication Agents, the Lenders and each of their respective directors,
officers, employees, attorneys, agents and Affiliates against, and hold each of
them harmless from, any loss, liabilities, damages, claims (including and to the
extent permitted by applicable law, any claim on any theory of liability for
special, indirect, consequential or punitive damages (as opposed to direct or
actual damages)), together with reasonable costs and expenses, joint or several,
(including reasonable attorneys' fees and disbursements reasonably incurred by
any such Person in connection with the preparation for or defense of any pending
or threatened claim, action or proceeding) suffered or incurred by any of them
under any applicable federal or state law or otherwise caused by, arising out
of, resulting from or in any manner connected with, the execution, delivery and
performance of each of the Loan Documents, the Loans and any and all
transactions related to or consummated in connection with the Loans or the
Letters of Credit. The indemnity set forth in

                                     - 81 -
<PAGE>

this Section 9.15 shall be in addition to any other obligations or liabilities
of the Borrower to the Agent, the Syndication Agents or the Lenders, or at
common law or otherwise. The provisions of this Section 9.15 shall survive the
payment of the Bank Indebtedness and the termination of this Agreement. The
foregoing provisions of this Section 9.15 to the contrary notwithstanding, the
Borrower shall not be obligated to indemnify the Agent, the Syndication Agents
or any Lender pursuant to this Section 9.15 for any losses, liabilities,
damages, claims, or costs which arise directly from the Agent's, such
Syndication Agent's or such Lender's gross negligence or willful misconduct. All
amounts owed pursuant to this Section 9.15 shall be part of the Bank
Indebtedness.

9.16  TERMINATION OF EXISTING BANK CREDIT AGREEMENTS. It is the intent of the
parties hereto that on the Closing Date the Borrower shall comply with each of
items (i) through (xiv) inclusive of Section 6.2. Upon satisfaction of all of
the provisions of Section 6.1 and Section 6.2 and the satisfaction of the terms
of any applicable payoff letter delivered in connection with the Existing Credit
Agreement, the Existing Bank Credit Agreements shall be terminated.

9.17  COUNTERPARTS. This Agreement and any amendment, modification, extension or
renewal hereto or hereof may be executed in several counterparts and by each
party on a separate counterpart, each of which, when so executed and delivered,
shall be an original, but all of which together shall constitute but one and the
same instrument. In proving this Agreement or any amendment, modification,
extension or renewal, it shall not be necessary to produce or account for more
than one such counterpart signed by the other party against whom enforcement is
sought.

9.18  PERMITTED ADJUSTMENTS TO COMMITMENT PERCENTAGES AND SHORT TERM REVOLVING
CREDIT COMMITMENT PERCENTAGES. In the event a Non-Agreeing Lender is repaid in
full on the Short Term Revolving Credit Termination Date and no substitute
Lender assumes the Short Term Revolving Credit Commitment of the Non-Agreeing
Lender, the Agent will calculate the applicable Short Term Revolving Credit
Commitment Percentage and Commitment Percentage of each Lender based on the
reduced aggregate Short Term Revolving Credit Commitment. In the event the
Borrower elects the Term-Out Option for one or more Non-Agreeing Lenders, then
upon the execution and delivery by the Borrower of a Term Note to any
Non-Agreeing Lender, such Non-Agreeing Lender shall be deemed to have, so long
as the related Term Loan remains outstanding, but solely for the purpose of
determining the Required Lenders at any time that Term Loans outstanding and for
the purpose of defining the term "Commitment Percentage" as used in Section 8.5
hereof such a Non-Agreeing Lender shall have a Commitment Percentage based on
the ratio of the outstanding principal balance of the Term Loan at the time of
determination to the sum of the aggregate outstanding Commitments plus the
outstanding Term Loans; and in such event the Commitment Percentages of the
other Lenders will be adjusted to reflect the funded Term Loan then outstanding
and due to Non-Agreeing Lender(s).

9.19  WAIVER OF CONSEQUENTIAL DAMAGES. To the extent permitted by applicable
law, the Borrower hereby waives its right to pursue any claim against the Agent,
the Syndication Agents, the Lenders and each of their respective directors,
officers, employees, attorneys, agents

                                     - 82 -
<PAGE>

and Affiliates on any theory of liability for special, indirect, consequential
or punitive damages (as opposed to direct or actual damages).

         Re:      Credit Agreement

Ladies and Gentlemen:

                  I have served as counsel to Allegheny Technologies
Incorporated (the "Borrower") in connection with the Credit Agreement by and
among the Borrower, the Lenders party thereto,
________________________________________________________________, as Syndication
Agents, and PNC Bank, National Association, as Documentation and Administrative
Agent thereunder dated as of December __, 2001 (the "Agreement"). You have
requested that I furnish to you my written opinion pursuant to Section _____ of
the Agreement. Terms not otherwise defined herein shall have the meanings
assigned to them in the Agreement.

                  I have reviewed the Agreement and Notes and such corporate
records of the Borrower, certificates of public officials, certificates of
officers of the Borrower and other documents and have made such examinations of
law as I have deemed necessary or relevant in connection with the opinions set
forth below.

                  I have also assumed, with your permission, the following:

                                     - 20 -
<PAGE>

         (i) the due completion and execution by duly authorized officers of
each Lender and the Agent and delivery of all documents and instruments to be
delivered by the Lenders and the Agent, if any; and

         (ii) that each of the Lenders and the Agent is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization or formation, that the Agreement constitutes the legal and binding
obligation of such Lender or the Agent, that the Agreement has been duly
authorized by all necessary action by each Lender and the Agent, and that each
Lender and the Agent has full corporate power and authority to perform its
obligations under the Agreement.

               I am a member of the Bar of the Commonwealth of Pennsylvania and
am opining herein only as to the effect on the subject transactions of the laws
of the Commonwealth of Pennsylvania (excluding conflict of laws rules), the
General Corporation Law of the State of Delaware and the federal laws of the
United States of America to the extent referred to specifically herein, all in
effect on the date hereof I express no opinion with respect to the laws of any
other jurisdiction.

               Based upon and subject to the foregoing as well as to the
additional qualifications and other matters hereinafter set forth, I am of the
opinion that:

               1. The Borrower is a corporation validly organized and existing
as a corporation under the laws of the State of Delaware.

               2. The Borrower has all requisite corporate power and authority
to own and operate its properties and assets and carry on its business as
presently conducted.

               3. The execution and delivery of the Agreement and the Notes by
the Borrower and the performance by the Borrower of its obligations under the
Agreement and the Notes have been duly authorized by all necessary corporate
action on the part of the Borrower The Borrower has the corporate power and
authority to enter into and perform its obligations under the Agreement and the
Notes.

               4. The execution and delivery of the Agreement and the Notes and
the performance by the Borrower of its obligations thereunder (A) do not violate
any provision of W the Borrower's Restated Certificate of Incorporation or its
Amended and Restated By-Laws, (ii) any material law binding upon or affecting
the Borrower, or (iii) any material agreement to which the Borrower is a party
or by which it or its properties are bound, or (B) result in the creation or
imposition of any Encumbrance in, of or on the property of the Borrower pursuant
to the terms of any such material agreement The Agreement and the Notes
constitute legal, valid binding obligations of the Borrower, enforceable in
accordance with their terms.

               5. Neither the execution and delivery nor the performance of the
Agreement and the Notes requires the giving of notice to, filing with, or
consent or approval of or other action by, any Governmental Authority except to
the extent that such notice or filing has been or will be accomplished or
obtained in the ordinary course without violating applicable law.

               6. The Borrower is not an "investment company" within the meaning
of the Investment Company Act of 1940, as amended, or "holding company", or an
"affiliate" of

                                     - 21 -
<PAGE>

a "holding company" or "subsidiary company" of a "holding company", within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

                           The opinions set forth herein are subject to the
following qualifications:

                  A. Insofar as the enforceability and binding effect of the
Agreement and Notes are concerned, the opinions set forth herein are subject to
limitations arising pursuant to applicable bankruptcy, insolvency, moratorium,
fraudulent transfer, preference and other laws and equitable principles
affecting the scope and enforcement of creditors, rights generally, and are also
limited by the Lenders' and the Agent's implied covenants of good faith, fair
dealing and commercially reasonable conduct, and by the effect of judicial
discretion on the availability of remedies and realization of benefits under the
enforceability of the Agreement and the Notes in all respects as written,
including, but not limited to, the recovery of attorneys, fees.

                  B. I express no opinion as to the enforceability of any
provision in any of the Agreement or the Notes (i) purporting to preclude the
modification of the Agreement or the Notes through conduct, custom or course of
performance, action or dealing, (ii) purporting to waive defenses or equitable,
constitutional or statutory rights or remedies, (iii) purporting to require the
payment or reimbursement or prepayment premiums, penalties, fees, costs,
expenses or other amounts which are unreasonable in nature or amount, (iv)
purporting to limit the liability of any Lender or the Agent or to indemnify any
Lender or the Agent for its acts or omissions, (v) constituting waivers of or
indemnification against violations by any Lender or the Agent, (vi) purporting
to restrict or prohibit the ability of the Borrower to transfer rights in the
property, or (vii) purporting to waive or restrict the right to a jury trial,
specify a means for service of process, select venue or consent to personal
jurisdiction.

                  Further and in response to your request, be advised that, to
my knowledge, except as set forth or incorporated by reference in the Borrower's
Registration Statement on Form S-4 filed under the Securities Act of 1933, as
amended, Registration No. 333-8235, or in the Forms 10-K, 10-Q or 8-K most
recently filed by Allegheny Ludlum Corporation and Teledyne, Inc., respectively,
there are no actions, suits, investigations, litigation or governmental
proceedings pending or, to my knowledge, threatened against or affecting the
Borrower or any of its Consolidated Subsidiaries before any court or arbitrator
or by or before any administrative agency or other governmental authority which
would have a Material Adverse Effect on the Borrower and its Consolidated
Subsidiaries taken as a whole, or which purport to affect the legality, validity
or enforceability of the Agreement or the Notes.

                  This letter is furnished to you specifically in connection
with the Agreement and solely for your information and benefit. It may not be
relied upon in any manner or for any other purpose by any other person without
my prior written consent. This opinion is rendered as of the date hereof, and I
have not undertaken to supplement this opinion with respect to factual matters
or changes of law that may occur hereafter. It is limited to the matters set
forth herein, and no opinion may be inferred or implied beyond the matters
expressly stated herein.

                                              Yours truly,

                                              Jon D. Walton
