         multiples of $100,000 in excess of such amount, and specifying the
         applicable Interest Period which shall be six months if the Borrower
         fails to specify the applicable Interest Period. On the terms and
         subject to the conditions of this Note, each LIBOR Rate Tranche shall
         be made available to the Borrower no later than 11:00 a.m. (prevailing
         time in Pittsburgh, Pennsylvania) on the first day of the applicable
         Interest Period by deposit to the account of the Borrower with the Bank
         or by wire transfer in accordance with written instructions as shall
         have been delivered to the Bank by the Borrower prior to the making of
         the requested LIBOR Rate Tranche. After giving effect to any borrowing,
         there shall not be more than three (3) LIBOR Rate Tranches outstanding
         at any time.

                  (c) By delivering an irrevocable written notice of
continuation/conversion to the Bank in a form acceptable to the Bank (a "Notice
of Continuation/Conversion")(or telephonic notice confirmed on the same day in a
Notice of Continuation/Conversion), the Borrower may from time to time
irrevocably elect to convert on the last day of an Interest Period any
outstanding Tranche to a Tranche bearing interest at a different Interest Rate
Option or having a different Interest Period, or continue on the last day of an
Interest Period a Tranche as a Tranche bearing interest at the same Interest
Rate Option with a similar Interest Period, subject to the following conditions:

                           (i) any Tranche to be continued as, or converted
         into, a LIBOR Rate Tranche must be in a minimum amount of $500,000 and
         integral multiples of $100,000 in excess of such amount;

                           (ii) no portion of a LIBOR Rate Tranche may be
         converted to, or continued as, a LIBOR Rate Tranche when an Event of
         Default has occurred and is continuing,

                           (iii) no portion of a LIBOR Rate Tranche may be
         converted to a LIBOR Rate Tranche of a different duration if such LIBOR
         Rate Tranche relates to any Hedging Contract, and

                           (iv) there shall be no more than three (3) LIBOR Rate
         Tranches outstanding at any time.

                           (v) each Notice of Conversion/Continuation must be
         received by the Bank (A) not later than 11:00 a.m. (prevailing time in
         Pittsburgh, Pennsylvania) at least two (2) Business Days in advance of
         the date of the requested date of continuation/conversion (the
         "Continuation/Conversion Date") if the Tranche is to be converted into
         or continued as a LIBOR Rate Tranche, or (B) not later than 11:00 a.m.
         (prevailing time in Pittsburgh, Pennsylvania) on the
         Continuation/Conversion Date, if the Tranche is to be converted into a
         Prime Rate Tranche or a LIBOR Advantage Tranche.

If no Interest Rate Option is timely selected at the end of any Interest Period
for a LIBOR Rate Tranche, the Borrower shall be deemed to have selected the
LIBOR Advantage Option for such Tranche. In the absence of a timely delivery of
a Notice of Continuation/Conversion with respect to any LIBOR Rate Tranche, such
Tranche shall, on the last day of the Interest Period relating to such Tranche
automatically convert to a LIBOR Advantage Tranche. If no Interest Rate Option
is timely selected at the end of any Interest Period for a LIBOR Advantage
Tranche, such Tranche shall automatically continue on the last day of the
Interest Period as a LIBOR Advantage Tranche with a similar Interest Period.

                                       6
<PAGE>

                  (d) Upon the occurrence and during the continuance of an Event
of Default, any outstanding LIBOR Rate Tranche or LIBOR Advantage Tranche may,
at the Bank's sole option, be converted to a Prime Rate Tranche on the last day
of the Interest Period relating thereto ending during the continuance of such
Event of Default.

                  (e) Each determination of an interest rate by the Bank shall
be conclusive and binding on the Borrower in the absence of manifest error. At
the request of the Borrower, the Bank will deliver to the Borrower a statement
showing the quotations used by the Bank in determining any interest rate and the
resulting interest rate. The Borrower may enter into Hedging Contracts covering
up to $300,000 of the outstanding principal amount of this Note or such greater
amount as may be approved in writing by the Bank in its sole discretion from
time to time. Any Hedging Contract will be cross-collateralized (to the extent
applicable), cross-defaulted, and cross-guaranteed (to the extent applicable)
with this Note. The fixed rate will be established the day that the Borrower
enters into a swap transaction with the Bank or its Affiliates.

                  (f) Interest shall be calculated on the basis of a 360-day
year, counting the actual number of days elapsed in the period during which it
accrues. The Borrower shall pay interest in arrears on each Interest Payment
Date and on the date the Bank makes demand for the payment in full of the
outstanding principal balance of this Note. In computing interest on any Line of
Credit Advance, the Borrowing Date or the first day of an Interest Period
applicable to such Line of Credit Advance shall be included, and the date of
payment of such Line of Credit Advance or the expiration date of an Interest
Period applicable to such Line of Credit Advance shall be excluded, provided,
that if a Line of Credit Advance is repaid on the same day on which it is made,
one day's interest shall be paid on that Line of Credit Advance.

                  (g) After the occurrence of an Event of Default (as
hereinafter defined), whether or not the Bank has made demand for payment,
interest shall accrue on the unpaid principal balance of this Note, before and
after judgment, at a rate per annum for each day equal to the Prime Rate plus
two percent (2.0%), and such interest shall be due and payable on demand.

                  (h) If, at any time, the rate of interest payable hereunder
shall be deemed by a competent court of law, governmental agency or tribunal to
exceed the maximum rate of interest permitted by applicable law, then for such
time as such rate would be deemed excessive, its application shall be suspended
and there shall be charged in lieu thereof the maximum rate of interest
permitted under such law. If any payment of interest or in the nature of
interest would cause the foregoing interest rate limitation to be exceeded, then
such excess payment shall be credited as a payment of principal, unless the
Borrower notify the Bank to return the excess payment to the Borrower.

                  (i) If the Bank shall reasonably determine (which
determination shall, upon notice thereof to the Borrower be conclusive and
binding on the Borrower) that the introduction of or any change in or in the
interpretation of any law, rule, regulation or guideline (whether or not having
the force of law) makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for the Bank to make, continue or
maintain any LIBOR Rate Tranche as, or to convert any loan into, a LIBOR Rate
Tranche of a certain duration, the obligations of the Bank to make, continue,
maintain or convert into any such LIBOR Rate Tranches shall, upon such
determination, forthwith be suspended until the Bank shall notify the Borrower
that the circumstances causing such suspension no longer exist, and all LIBOR
Rate Tranches of such type shall automatically convert into LIBOR Advantage
Tranches at the end of the then current Interest Periods with respect thereto or
sooner, if required by such law or assertion.

                  (j) If the Bank determines that it is unlawful to maintain any
LIBOR Rate Tranche, the Borrower shall, upon its receipt of notice of such fact
and demand from the Bank, prepay in full such

                                       7
<PAGE>

LIBOR Rate Tranches then outstanding, together with interest accrued thereon and
the LIBOR Rate Prepayment Fee, either on the last day of the Interest Period
thereof, if the Bank may lawfully continue to maintain such LIBOR Rate Tranches
to such day, or immediately, if the Bank may not lawfully continue to maintain
such LIBOR Rate Tranche. If the Borrower is required to so prepay any LIBOR Rate
Tranche, then concurrently with such prepayment, the Borrower shall borrow a
Prime Rate Tranche from the Bank in the amount of such prepayment.

                  (k) If the Bank shall have determined that (i) US dollar
deposits in the relevant amount and for the relevant Interest Period are not
available to the Bank in the London interbank market, (ii) by reason of
circumstances affecting the Bank in the London interbank, adequate means do not
exist for ascertaining the LIBOR Rate applicable hereunder to LIBOR Rate
Tranches of any duration, or (iii) the LIBOR Rate no longer adequately reflects
the Bank's cost of funding loans, then, upon notice from the Bank to the
Borrower, the obligations of the Bank to make or continue any Tranches as, or to
convert any Tranches into, LIBOR Rate Tranches of such duration shall forthwith
be suspended until the Bank shall notify the Borrower that the circumstances
causing such suspension no longer exist.

                  (l) If the obligation of the Bank to make or maintain LIBOR
Rate Tranches has been so terminated or suspended, the Borrower may elect, by
giving notice to the Bank that all Tranches which would otherwise be made by the
Bank as LIBOR Rate Tranches shall instead be made as LIBOR Advantage Tranches;
until such notice is delivered, if at all, all Tranches shall be LIBOR Advantage
Tranches.

                  (m) In addition to the LIBOR Rate Prepayment Fee, the Borrower
agrees to reimburse the Bank (without duplication) for any increase in the cost
to the Bank, or reduction in the amount of any sum receivable by the Bank, in
respect, or as a result of:

                           (i) any conversion or repayment or prepayment of the
         principal amount of any LIBOR Rate Tranches on a date other than the
         scheduled last day of the Interest Period applicable thereto;

                           (ii) any Tranches not being made as LIBOR Rate
         Tranches in accordance with the borrowing request thereof;

                           (iii) any LIBOR Rate Tranche not being continued as,
         or converted into, a LIBOR Rate Tranche in accordance with the Notice
         of Continuation/Conversion thereof, or

                           (iv) any costs associated with marking to market any
         Hedging Obligations that (in the reasonable determination of the Bank)
         are required to be terminated as a result of any conversion, repayment
         or prepayment of the principal amount of any LIBOR Rate Tranche on a
         date other than the scheduled last day of the Interest Period
         applicable thereto;

The Bank shall promptly notify the Borrower in writing of the occurrence of any
such event, such notice to state, in reasonable detail, the reasons therefor and
the additional amount required fully to compensate the Bank for such increased
cost or reduced amount. Such additional amounts shall be payable by the Borrower
to the Bank within five days of its receipt of such notice, and such notice
shall, in the absence of manifest error, be conclusive and binding on the
Borrower. The Borrower understands, agrees and acknowledges the following: (i)
the Bank does not have any obligation to purchase, sell and/or match funds in
connection with the use of LIBOR Rate as a basis for calculating the rate of
interest on a LIBOR Rate Tranche, (ii) the LIBOR Rate may be used merely as a
reference in determining such rate, and

                                       8
<PAGE>

(iii) the Borrower has accepted the LIBOR Rate as a reasonable and fair basis
for calculating such rate, the LIBOR Rate Prepayment Fee, and other funding
losses incurred by the Bank. Borrower further agrees to pay the LIBOR Rate
Prepayment Fee and other funding losses, if any, whether or not the Bank elects
to purchase, sell and/or match funds.

                  (n) If on or after the date hereof the adoption of any
applicable law, rule or regulation or guideline (whether or not having the force
of law), or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the Bank with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency:

                           (i) shall subject the Bank to any tax, duty or other
         charge with respect to its LIBOR Rate Tranches or its obligation to
         make LIBOR Rate Tranches, or shall change the basis of taxation of
         payments to the Bank of the principal of or interest on its LIBOR Rate
         Tranches or any other amounts due under this agreement in respect of
         its LIBOR Rate Tranches or its obligation to make LIBOR Rate Tranches
         (except for the introduction of, or change in the rate of, tax on the
         overall net income of the Bank or franchise taxes, imposed by the
         jurisdiction (or any political subdivision or taxing authority thereof)
         under the laws of which the Bank is organized or in which the Bank's
         principal executive office is located); or

                           (ii) shall impose, modify or deem applicable any
         reserve, special deposit or similar requirement (including, without
         limitation, any such requirement imposed by the Board of Governors of
         the Federal Reserve System of the United States) against assets of,
         deposits with or for the account of, or credit extended by, the Bank or
         shall impose on the Bank or on the London interbank market any other
         condition affecting its LIBOR Rate Tranches or its obligation to make
         LIBOR Rate Tranches;

         and the result of any of the foregoing is to increase the cost to the
         Bank of making or maintaining any LIBOR Rate Tranche, or to reduce the
         amount of any sum received or receivable by the Bank under this
         Agreement with respect thereto, by an amount deemed by the Bank to be
         material, then, within 15 days after demand by the Bank, the Borrower
         shall pay to the Bank such additional amount or amounts as will
         compensate the Bank for such increased cost or reduction.

                  (o) If any change in, or the introduction, adoption,
effectiveness, interpretation, reinterpretation or phase-in of, any law or
regulation, directive, guideline, decision or request (whether or not having the
force of law) of any court, central bank, regulator or other governmental
authority affects or would affect the amount of capital required or expected to
be maintained by the Bank, or person controlling the Bank, and the Bank
determines (in its sole and absolute discretion) that the rate of return on its
or such controlling person's capital as a consequence of its commitments or the
loans made by the Bank is reduced to a level below that which the Bank or such
controlling person could have achieved but for the occurrence of any such
circumstance, then, in any such case upon notice from time to time by the Bank
to the Borrower, the Borrower shall immediately pay directly to the Bank
additional amounts sufficient to compensate the Bank or such controlling person
for such reduction in rate of return. A statement of the Bank as to any such
additional amount or amounts (including calculations thereof in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
the Borrower. In determining such amount, the Bank may use any reasonable method
of averaging and attribution that it (in its sole and absolute discretion) shall
deem applicable.

                  (p) All payments by the Borrower of principal of, and interest
on, the LIBOR Rate Tranches and all other amounts payable hereunder shall be
made free and clear of and without deduction for any present or future income,
excise, stamp or franchise taxes and other taxes, assessments, imposts, duties,
deductions, fees, withholdings or similar charges, and all liabilities with
respect thereto of any nature whatsoever imposed by any taxing authority, but
excluding franchise taxes and taxes imposed on or measured by the Bank's net
income or receipts (such non-excluded items being called "Taxes"). In the event
that any withholding or deduction from any payment to be made by the Borrower
hereunder is required in respect of any Taxes pursuant to any applicable law,
rule or regulation, then the Borrower will

                           (i) pay directly to the relevant authority the full
         amount required to be so withheld or deducted;

                           (ii) promptly forward to the Bank an official receipt
         or other documentation satisfactory to the Bank evidencing such payment
         to such authority; and

                           (iii) pay to the Bank such additional amount or
         amounts as is necessary to ensure that the net amount actually received
         by the Bank will equal the full amount the Bank would have received had
         no such withholding or deduction been required.

                  (q) If any Taxes are directly asserted against the Bank with
respect to any payment received by the Bank hereunder, the Bank may pay such
Taxes and the Borrower will promptly pay such additional amount (including any
penalties, interest or expenses) as is necessary in order that the net amount
received by the Bank after the payment of such Taxes (including any Taxes on
such additional amount) shall equal the amount the Bank would have received had
not such Taxes been asserted.

                  (r) If the Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to the Bank the required receipts
or other required documentary evidence, the Borrower shall indemnify the Bank
for any incremental Taxes, interest or penalties that may become payable by the
Bank as a result of any such failure.

                  (s) The agreements and obligations of the Borrower in
Paragraph 2(i) through (r) shall survive the payment in full of the outstanding
principal balance of this Note.

         3. Payments; LIBOR Rate Prepayment Fee. (a) The outstanding principal
balance of this Note is due and payable ON DEMAND. Interest accrued on this Note
shall be due and payable in accordance with the provisions of Paragraph 2(f).

                  (b) Unless demand has been made prior thereto, each LIBOR Rate
Tranche shall mature and become payable in full on the last day of the Interest
Period relating to such LIBOR Rate Tranche. Upon maturity, a LIBOR Rate Tranche
may be continued for an additional Interest Period or may be converted as
permitted under Paragraph 2. LIBOR Rate Tranches may be prepaid upon the terms
and conditions set forth herein. For LIBOR Rate Tranches in connection with
which the Borrower has entered into Hedging Contracts, additional obligations
may be associated with prepayment, in accordance with the terms and conditions
of the applicable Hedging Contracts. The Borrower shall give the Bank, no later
than 10:00 a.m. (prevailing time in Pittsburgh, Pennsylvania) at least four (4)
Business Days prior notice of any proposed prepayment of any LIBOR Rate
Tranches, specifying the proposed date of payment of such LIBOR Rate Tranches,
and the principal amount to be paid. Each partial prepayment of the principal
amount of LIBOR Rate Tranches shall be in an integral multiple of $500,000 and
accompanied by the payment of all charges outstanding on such LIBOR Rate
Tranches and of all accrued interest on the principal repaid to the date of
payment. The Borrower acknowledges that prepayment or

                                       10
<PAGE>

acceleration of a LIBOR Rate Tranche during an Interest Period shall result in
the Bank incurring additional costs, expenses and/or liabilities and that it is
extremely difficult and impractical to ascertain the extent of such costs,
expenses and/or liabilities. Therefore, all full or partial prepayments of LIBOR
Rate Tranches shall be accompanied by, and the Borrower hereby promises to pay,
on each date a LIBOR Rate Tranche is prepaid or the date all sums payable
hereunder become due and payable, by acceleration or otherwise, in addition to
all other sums then owing, an amount (the "LIBOR Rate Prepayment Fee")
determined by the Bank pursuant to the following formula:

                           (i) the then current rate for United States Treasury
         securities (bills on a discounted basis shall be converted to a bond
         equivalent) with a maturity date closest to the end of the Interest
         Period as to which prepayment is made, subtracted from

                           (ii) the LIBOR Lending Rate plus the Applicable
         Margin applicable to the LIBOR Rate Tranche being prepaid.

If the result of this calculation is zero or a negative number, then there shall
be no LIBOR Rate Prepayment Fee. If the result of this calculation is a positive
number, then the resulting percentage shall be multiplied by the amount of the
LIBOR Rate Tranche being prepaid, and the resulting amount shall be divided by
360, and multiplied by the number of days remaining in the Interest Period as to
which the prepayment is being made. Said amount shall be reduced to present
value calculated by using the referenced United States Treasury securities rate
and the number of days remaining on the Interest Period for the LIBOR Rate
Tranche being prepaid. The resulting amount of these calculations shall be the
LIBOR Rate Prepayment Fee.

                  (c) All sums to be paid to the Bank under this Note shall be
paid directly to the Bank's Office on or before 2:00 p.m. prevailing time in
Pittsburgh, Pennsylvania, on the day when due, in lawful money of the United
States of America and in immediately available funds (subject to clearance),
without set-off, counterclaim or other deduction of any nature and without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived by the Borrower, and any action therefor shall immediately
accrue. Payments received after such time shall be deemed received by the Bank
on the next succeeding Business Day at such place of payment. All payments shall
be made free and clear of, and without deduction for, any present or future
taxes, levies, withholding, offsets, counterclaims or deductions of any nature
whatsoever ("Deductions"). In the event that the Borrower is compelled for any
reason to make any Deductions, the Borrower shall pay to the Bank such amounts
(after giving effect to all Deductions on all additional payments to be made
hereunder) as will result in the receipt by the Bank of the amount the Bank
would have received had no such Deductions been required to be made. Payments
shall be credited first to charges, fees and expenses accrued on this Note,
second to interest accrued on this Note and the remainder to reduction of the
outstanding principal balance hereof. Any payment otherwise due on a day which
is not a Business Day shall not be due until the next succeeding Business Day.

                  (d) In the event the Borrower fails to make any payment under
this Note within fifteen (15) days of when due (whether at maturity, upon the
occurrence of an Event of Demand, by acceleration or otherwise), in addition to
making payment of the amount then due, the Borrower shall, at the option of the
Bank, pay to the Bank a late charge in an amount equal to five percent (5.0%) of
such overdue amount. The foregoing late payment fees shall be immediately due
and payable without presentment, demand or notice by Bank

         4. Bank's Records. The Bank is hereby authorized to record in its books
and records the amount of all Line of Credit Advances, principal payments,
interest due, interest paid, and all other charges, fees and expenses paid or
due, and the like, under or in connection with this Note, and except in

                                       11
<PAGE>

the case of manifest error, such books and records shall be conclusive and
binding as to the amounts at any time due to the Bank from the Borrower under
this Note.

         5. Events of Default. The occurrence or existence of any one or more of
the following events or conditions (whatever the reason for such occurrence or
existence and whether voluntary, involuntary or effected by operation of Law)
shall constitute an "Event of Default" under this Note, however, THE BORROWER
ACKNOWLEDGES THAT THE OUTSTANDING PRINCIPAL BALANCE OF THIS NOTE IS PAYABLE ON
DEMAND AND THE ENUMERATION OF EVENTS OF DEMAND, CONDITIONS OR COVENANTS IN ANY
OF THE LOAN DOCUMENTS SHALL NOT BE CONSTRUED TO QUALIFY, DEFINE OR OTHERWISE
LIMIT IN ANY WAY THE BANK'S RIGHT, POWER OR ABILITY, AT ANY TIME, TO MAKE DEMAND
FOR THE PAYMENT OF THE OUTSTANDING PRINCIPAL BALANCE OF, AND ALL INTEREST
ACCRUED ON, THIS NOTE, AND THE BORROWER AGREES THAT THE OCCURRENCE OF AN EVENT
OF DEMAND IS NOT A CONDITION FOR DEMAND TO BE MADE BY THE BANK FOR PAYMENT OF
THE OUTSTANDING PRINCIPAL BALANCE OF THIS NOTE:

                           (i) The failure of the Borrower to pay any principal,
         interest, fee, indemnity, expense or other amount when due under this
         Note.

                           (ii) The breach by any Obligor of any covenant
         contained in the Loan Agreement, this Note, or in any separate
         security, guarantee or suretyship agreement, between the Bank and any
         Obligor, or the occurrence of any default hereunder or under the terms
         of any such agreement.

                           (iii) Any representation or warranty made by or on
         behalf of the Borrower in any certificate, financial statement or other
         document furnished to the Bank in connection with this Note or the Loan
         Agreement shall prove to have been false or misleading.

                           (iv) An Insolvency Proceeding shall be instituted by
         the Borrower or any other Obligor with respect to itself and its
         properties, or a Borrower or any other Obligor shall take any action in
         furtherance of any such Insolvency Proceeding.

                           (v) An Obligor (A) has an involuntary Insolvency
         Proceeding commenced or filed against it and any such proceeding or
         petition shall not be dismissed within sixty (60) days after
         commencement; (B) admits the material allegations of a petition in any
         Insolvency Proceeding, or an order for relief (or similar order under
         non-U.S. law) is ordered in any Insolvency Proceeding; or (iii)
         acquiesces in the appointment of a receiver, trustee, custodian,
         conservator, liquidator, mortgagee in possession (or agent therefor),
         or other similar person for itself or a substantial portion of its
         property or business.

                           (vi) An Obligor shall (A) become insolvent, or
         generally fail to pay, become unable to pay, or state that it is or
         will be unable to pay, its debts as they become due, or (B) make a
         general assignment for the benefit of creditors.

                           (vii) This Note, the Loan Agreement or any separate
         security, guarantee or suretyship agreement between the Bank and any
         Obligor, or any material term or provision thereof, shall cease to be
         in full force and effect (except in accordance with the express terms
         thereof), or an Obligor shall, or shall purport to, terminate (except
         in accordance with the terms hereof), repudiate, declare voidable or
         void or otherwise

                                       12
<PAGE>

         contest, this Note, the Loan Agreement or any separate security,
         guarantee or suretyship agreement between the Bank and any Obligor or
         any material term or provision hereof or thereof or any obligation or
         liability of an Obligor hereunder or thereunder.

                           (viii) The garnishment, attachment or taking by
         governmental authority of any property of the Borrower which is in the
         Bank's possession or which constitutes security for any indebtedness
         evidenced hereby.

                           (ix) A notice of lien or assessment in excess of
         $20,000 is filed of record with respect to all or any portion of the
         Borrower's assets by the United States of America, or any department,
         agency, or instrumentality thereof, or by any state, county, municipal,
         or other governmental agency.

         6. Consequences of an Event of Default; Remedies. (a) If an Event of
Default other than those specified in Paragraph 5(iv) or (v) hereof shall occur,
then, at the Bank's option, the unpaid principal balance of this Note and all
interest, fees, expenses and other charges accrued hereon may become immediately
due and payable without demand, presentment or notice of any kind (all of which
the Borrower hereby waives). THE FOREGOING SHALL NOT BE CONSTRUED TO LIMIT THE
BANK'S RIGHT TO DEMAND PAYMENT AT ANYTIME OF THE INDEBTEDNESS NOW OR HEREAFTER
EVIDENCED BY THIS NOTE WHETHER OR NOT AN EVENT OF DEFAULT HAS OCCURRED.

                  (b) If an Event of Default specified in Paragraph 5(iv) or (v)
hereof occurs, then the unpaid principal balance of this Note and all interest,
fees, expenses and other charges accrued hereon shall be immediately due and
payable without demand, presentment or notice of any kind (all of which the
Borrower hereby waives). THE FOREGOING SHALL NOT BE CONSTRUED TO LIMIT THE
BANK'S RIGHT TO DEMAND PAYMENT AT ANYTIME OF THE INDEBTEDNESS NOW OR HEREAFTER
EVIDENCED BY THIS NOTE WHETHER OR NOT AN EVENT OF DEFAULT HAS OCCURRED.

                  (c) After the occurrence of an Event of Default, the Bank may
set-off and apply against the unpaid principal balance of this Note and all
interest, fees, expenses and other charges accrued hereon, any and all debts
owing to, and any other funds held in any manner for the account of, the
Borrower by the Bank, including, without limitation, all deposit accounts
(general or special, time or demand, provisional or final) at any time
maintained by the Borrower with the Bank and any other indebtedness at any time
owing by the Bank to or for the account of the Borrower, irrespective of whether
or not the Bank shall have made any demand under this Note. In addition to and
independent of the Bank's right of set-off and to secure the payment of this
Note and all other liabilities, the Borrower grants to the Bank a continuing
lien upon and security interest in any and all monies, securities, and other
property of the Borrower and the proceeds thereof, now or hereafter held or
received by or in transit to the Bank from or for the Borrower, and also upon
any and all deposit (general or special), agency, escrow, and other accounts and
credits of the Borrower at the Bank, at any time and from time to time existing.

                  (d) The following paragraph sets forth a warrant of authority
for an attorney to confess judgment against the Borrower. In granting this
warrant to confess judgment against the Borrower, the Borrower hereby knowingly,
intentionally, voluntarily and, on the advice of separate counsel,
unconditionally waives any and all rights the Borrower has or may have to prior
notice and an opportunity for hearing before a judgment can be entered
hereunder:

         THE BORROWER UNCONDITIONALLY AND IRREVOCABLY AUTHORIZES AND EMPOWERS
ANY ATTORNEY OR ANY PROTHONOTARY, CLERK OF COURT OR COURT

                                       13
<PAGE>

OF RECORD, AS ATTORNEY FOR THE BORROWER, TO APPEAR FOR THE BORROWER IN SUCH
COURT AT ANY TIME AFTER THE OCCURRENCE OF AN EVENT OF DEFAULT AND CONFESS
JUDGMENT AGAINST THE BORROWER, IN FAVOR OF THE BANK, AND ITS SUCCESSORS AND
ASSIGNS, FOR ALL OR ANY PORTION OF THE OUTSTANDING PRINCIPAL BALANCE OF THIS
NOTE, TOGETHER WITH UNPAID INTEREST, COSTS OF SUIT AND ATTORNEYS' FEES ADDED FOR
COLLECTION IN AN AMOUNT EQUAL TO THE LESSER OF (1) TWENTY PERCENT (20.0%) OF
SUCH SUM AND INTEREST THEN DUE HEREUNDER OR $500.00, WHICHEVER IS GREATER, OR
(2) THE MAXIMUM PERMITTED BY LAW. THE BORROWER ALSO RELEASES ALL ERRORS, AND TO
THE EXTENT PERMITTED BY LAW, WAIVES AND RELEASES ALL RELIEF FROM ANY AND ALL
APPRAISEMENT, STAY OR EXEMPTION LAW OF ANY STATE NOW IN FORCE OR HEREAFTER
ENACTED. IF A COPY OF THIS NOTE, VERIFIED BY AFFIDAVIT OF THE BANK OR SOMEONE ON
BEHALF OF THE BANK, SHALL HAVE BEEN FILED IN SUCH ACTION, IT SHALL NOT BE
NECESSARY TO FILE AN ORIGINAL OF THIS NOTE AS A WARRANT OF ATTORNEY. THE
AUTHORITY AND POWER TO APPEAR FOR AND ENTER JUDGMENT AGAINST THE BORROWER SHALL
NOT BE EXHAUSTED BY THE INITIAL EXERCISE THEREOF OR BY ANY IMPERFECT EXERCISE
THEREOF AND SHALL NOT BE EXTINGUISHED BY ANY JUDGMENT ENTERED PURSUANT THERETO;
THE AUTHORITY AND POWER MAY BE EXERCISED ON ONE OR MORE OCCASIONS, FROM TIME TO
TIME, IN THE SAME OR DIFFERENT JURISDICTIONS, AS OFTEN AS THE BANK SHALL DEEM
NECESSARY OR DESIRABLE, FOR ALL OF WHICH THIS NOTE OR A VERIFIED COPY HEREOF
SHALL BE A SUFFICIENT WARRANT. TO THE EXTENT PERMITTED BY LAW, INTEREST SHALL
ACCRUE ON ANY JUDGMENT AT THE RATE OF INTEREST WHICH WOULD ACCRUE ON THE UNPAID
PRINCIPAL BALANCE OF THIS NOTE UPON THE OCCURRENCE OF AN EVENT OF DEFAULT UNDER
THIS NOTE.

                  (e) If the Bank retains the services of counsel in connection
with an Event of Default or to enforce a remedy under this Note, reasonable
attorney's fees shall be payable by the Borrower to the Bank, and such fees
shall be added to the amount due under this Note. The Borrower shall pay all
costs incurred by the Bank in connection with proceedings to recover any sums
due hereunder. The Borrower shall also pay any reasonable charge of the Bank in
connection with the satisfaction of this Note.

                  (f) The remedies of the Bank as provided herein and all
warrants of attorney provided herein shall be cumulative and concurrent, and may
be pursued singly, successively, or together against the Borrower at the sole
discretion of the Bank, and such warrants shall not be exhausted by any exercise
thereof but may be exercised as often as the occasion therefor shall occur; and
the failure to exercise any such rights or remedy shall in no event be construed
as a waiver or release of the same.

         7. Representations and Certain Covenants. (a) The Borrower hereby
represents and warrants to the Bank that (i) this Note has been duly executed
and delivered by the Borrower and constitutes the legal, valid and binding
obligations of the Borrower enforceable in accordance with its terms, and (ii)
for so long as any indebtedness evidenced hereby remains outstanding the
Borrower's Chief Executive Office is as stated below or as otherwise stated in a
subsequent written notice delivered to the Bank pursuant to the terms hereof.
The Borrower hereby ratifies, confirms and reaffirms, without condition, all the
terms and conditions of the Loan Agreement and agrees that it continues to be
bound by the terms and conditions thereof.

                  (b) The Borrower covenants and agrees that until all

writing of any change in its Chief Executive Office or jurisdiction of
formation; (iii) purchase and maintain

policies of insurance (including flood insurance) to protect against such risks
and casualties, and in such amounts, as shall be required by the Bank and/or
applicable law, which policies shall (A) be in form and substance satisfactory
to the Bank, (B) designate the Bank as loss payee and, at the Bank's option, as
additional insured, and (C) be (or certificates evidencing same shall be)

                  (c) The Borrower hereby authorizes the Bank, and the Bank
shall have the continuing right, at its sole option and discretion, to: (i) do
anything which the Borrower is required but fails to do hereunder, and in
particular the Bank may, if the Borrower fails to do so, obtain and pay any
premiums payable on any policy of insurance required to be obtained or
maintained hereunder, and add any amounts paid under this Paragraph 7(c) to the
principal amount of the indebtedness evidenced by this Note; or (ii) direct any
insurer to make payment of any insurance proceeds including any earned or
unearned premiums, directly to the Bank, and apply such moneys to any

Bank may elect

         8. Miscellaneous. (a) The Bank shall not be deemed, by any act of
omission or commission, to have waived any of its rights or remedies hereunder
unless such waiver is in writing and signed by the Bank, and then only to the
extent specifically set forth in the writing. A waiver as to one event shall not
be construed as continuing or as a bar to or waiver of any right or remedy as to
a subsequent event.

                  (b) Nothing herein contained nor any transaction related
hereto shall be construed or shall operate either presently or prospectively to
require the Borrower to make any payments or to do any act contrary to law, but
if any clause or provision herein contained shall otherwise so operate to
invalidate this Note, in whole or in part, then such clause or provision only
shall be held for naught as though not herein contained and the remainder of
this Note shall remain operative and in full force and effect.

                  (c) The provisions of this Note shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
or obligations under this Note without the prior written consent of the Bank,
such consent to be granted or withheld in the sole discretion of the Bank. The
Bank may, without notice to the Borrower and at any time whether or not this
Note is due (i) assign, pledge, or transfer this Note and any collateral
therefor, whereupon the Bank shall be relieved of all duties and
responsibilities hereunder and relieved from any and all liability with respect
to any collateral so pledged or transferred, and the rights and privileges of
the Bank under this Note shall inure to the benefit of its successors, assigns,
and any pledgee or transferee hereof, who shall for all purposes stand in the
place of the Bank and have all the rights of the Bank hereunder; (ii) grant
participations in this Note and other Loan Documents and the transactions
evidenced thereby; (iii) exercise all rights necessary or required, in the
Bank's sole discretion, to protect its interests hereunder; and (iv) provide
from time to time any information relating to the financial condition, business
preparations, or credit worthiness of the Borrower to or at the direction of any
governmental authority and to any person or entity which in the ordinary course
of its business makes credit reference inquiries or which may succeed to or
participate in all or part of the Bank's interest in this Note or any Line of
Credit Advance evidenced hereby.

                  (d) Any notice or consent required hereunder shall be in
writing and shall be delivered either in person, by facsimile transmission,
overnight courier or by certified mail, postage prepaid, return receipt
requested, to the addresses of the parties first above written, unless such
address is changed by written notice to the other parties. All notices and other
communications shall be deemed effective when delivered in person, when received
by registered or certified mail or overnight courier,

                                       15
<PAGE>

when transmitted by facsimile transmission during a Business Day (with
confirmation of receipt) or when refused by the addressee, as the case may be.

                  (e) The Bank shall in no event be construed for any purpose to
be a partner, joint venturer or associate of the Borrower or of any lessee,
operator, concessionaire or licensee of the Borrower in the conduct of their
respective businesses.

                  (f) This Note is intended as an instrument under seal and
shall be deemed made under and governed by, and construed and enforced in
accordance with, the laws of the Commonwealth of Pennsylvania in all respects
without giving effect to its conflict of laws principles, including matters of
construction, performance and enforcement. Each Borrower hereby agrees that any
action or proceeding against it may be commenced and maintained in any court in
the Commonwealth of Pennsylvania or in the United States District Court for the
Western District of Pennsylvania, and each Borrower further consents to service
of process in any such action by the mailing of copies of such process to the
Borrower in the manner and at the Borrower's Chief Executive Office. The
Borrower hereby waives any claim that Allegheny County, Pennsylvania is an
inconvenient forum and that any action or proceeding arising out of or relating
to this Note and commenced in any state or federal courts sitting in Allegheny
County, Pennsylvania lacks proper venue. The Borrower agrees that the courts
sitting in the Commonwealth of Pennsylvania and the United States District Court
for the Western District of Pennsylvania shall have exclusive jurisdiction for
any action or proceeding commenced by or through the Borrower with respect to
the subject matter hereof and all controversies and disputes arising hereunder.

                  (g) Wherever possible, each provision of this Note shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Note or portion thereof shall be prohibited by or
invalid under such law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Note.

                  (h) The Borrower waives and releases any right to require the
Bank to collect any of the indebtedness evidenced by this Note from any
particular collateral under any theory of marshalling of assets or otherwise and
specifically authorizes the Bank to apply any collateral for this Note in any
manner that the Bank, in its sole discretion, may determine. The Borrower
represents and warrants to the Bank that the proceeds of this Note will be used
solely for business or commercial purposes and agrees that any disbursement of
the proceeds of this Note, or any portion thereof, to or at the direction of the
Borrower whether for its own account or otherwise, shall be conclusively deemed
to constitute disbursement of such proceeds to and for the benefit of the
Borrower.

                  (i) THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE TO DEMAND A TRIAL BY JURY IN RESPECT
OF ANY LITIGATION ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR THE
TRANSACTIONS CONTEMPLATED HEREIN. FURTHER, EACH BORROWER HEREBY CERTIFIES THAT
NO REPRESENTATIVE OR AGENT OF THE BANK NOR THE BANK'S COUNSEL HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT, IN THE EVENT OF SUCH LITIGATION, THE BANK WOULD
NOT SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION. EACH BORROWER
FURTHER ACKNOWLEDGES THAT THE BANK HAS BEEN OR WILL BE INDUCED TO MAKE THE LINE
OF CREDIT ADVANCES EVIDENCED BY THIS NOTE BY, INTER ALIA, THE PROVISIONS OF THIS
PARAGRAPH.

                  (j) No delay or omission on the part of the Bank in exercising
any right hereunder shall operate as a waiver of such right or of any other
rights under this Note. Presentment, demand,

                                       16
<PAGE>

dishonor, protest, notice of dishonor, notice of protest and all other notices
and demands are hereby waived by the Borrower. The Borrower promises and agrees
to pay all costs, claims, taxes (other than taxes on the income of Bank),
penalties, judgments and expenses incurred by the Bank in connection with the
taking, administering, enforcing or collecting this Note or any other liability
or preserving any right or interest of the Bank hereunder including attorneys'
fees equal to the lesser of (A) 20% of the above sum and interest then due
hereunder or $500.00, whichever is greater, or (B) the maximum amount permitted
by law, and attorney's costs and all costs of legal proceedings.

                  (k) The Borrower hereby waives any and all now existing or
hereafter arising rights to recoup or offset any obligation of the Borrower
under or in connection with this Note against any claim or right of the Borrower
against the Bank.

                  (l) The Borrower hereby irrevocably appoints the Bank and each
holder hereof as the Borrower's attorney-in-fact to endorse the Borrower's name
to any draft or check which may be payable to the Borrower in order to collect
the proceeds of any insurance or any returned or unearned premiums in respect of
any policies of insurance required to be maintained hereunder.

                  (m) "Borrower" refers individually and collectively to all
makers of this Note, including, in the case of a partnership, all general
partners of such partnership individually and collectively, whether or not such
partners sign below, and each general partner shall be bound hereby both in such
general partner's individual and partnership capacities.

                  (n) The Borrower represents and warrants that the Bank has
duly performed or otherwise met all of its duties and obligations under the Loan
Agreement or otherwise owed to the Borrower and that there are no claims, causes
of action, suits, debts, liens, obligations, liabilities, demands, losses,
defenses, offsets, costs or expenses (including attorneys' fees) of any kind,
character or nature whatsoever, vested or contingent, at law, in equity or
otherwise (collectively, "Claims"), which the Borrower has or claims to have
against the Bank, arising out of or connected with any act or omission of the
Bank existing or occurring on or prior to the date of this Note.

                  (o) The Borrower releases, waives and forever discharges and
relieves the Bank and its subsidiaries and Affiliates and the officers,
directors, agents, attorneys and employees of each (hereinafter "Releasees")
from any and all Claims which the Borrower ever had, now has, or which may
result from the past or present state of things, against or related to
Releasees. The Borrower agrees to assume the risk of releasing any and all
unknown, unanticipated or misunderstood claims hereby.

         IN WITNESS WHEREOF, the Borrower, intending to be legally bound hereby,
has executed this Fifth Amended and Restated Note the day and year first above
written.

                                CREDIT AGREEMENT

         THIS CREDIT AGREEMENT (this "Agreement"), made effective as of the 3rd
day of June, 2004, is by and between BRADFORD RESOURCES, LTD., a Pennsylvania
limited partnership (the "Borrower"), SUPERIOR WELL SERVICES, LTD., a
Pennsylvania limited partnership ("Superior")and CITIZENS BANK OF PENNSYLVANIA,
a Pennsylvania state chartered bank (the "Lender").

                                   WITNESSETH:

         WHEREAS, the Borrower has requested the Lender to make a standby term
loan available to it in the principal amount of $10,000,000, and the Lender is
willing to make such a standby term loan available to the Borrower upon the
terms and conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, and intending to be legally bound hereby, the
Borrower and the Lender covenant and agree as follows:

ARTICLE I. DEFINITIONS AND INTERPRETATIONS

         SECTION 1.01 DEFINED TERMS AND INTERPRETATIONS. In addition to other
words and terms defined elsewhere in this Agreement (including the preamble and
recitals), when used in this Agreement and in the exhibits and schedules to this
Agreement, the capitalized words and terms set forth in Schedule One attached
hereto and incorporated herein by reference thereto shall have the meanings set
forth in Part I of Schedule One unless otherwise defined herein or the context
otherwise clearly requires. In addition, the provisions of Part II of Schedule
One shall, unless otherwise specified in this Agreement, apply to the
interpretation of the words and terms used herein.

         SECTION 1.02 ACCOUNTING MATTERS; CHANGES IN GAAP. (a) For purposes of
this Agreement and each of the other Loan Documents, all accounting and
financial terms used herein or therein shall be interpreted, all accounting
determinations and computations hereunder or thereunder shall be made, and all
financial statements required to be delivered hereunder or thereunder shall be
prepared, in accordance with GAAP.

                  (b) In the event that any accounting changes relating to GAAP
or other accounting principles and policies occur after the Closing Date and
such changes result in a change in the method of calculation of financial
covenants, standards or terms in this Agreement, then the Borrower and the
Lender agree to enter into negotiations in order to amend such provisions of
this Agreement to compensate for the effect of such changes so that the
restrictions, limitations and performance standards effectively imposed by such
covenants, as so amended, are substantially identical to the restrictions,
limitations and performance standards imposed by such covenants as in effect on
the Closing Date, provided, if the parties are unable to agree on an amendment
within a reasonable period of time, then calculation of compliance by the
Borrower with the covenants contained in this Agreement shall be determined in
accordance with GAAP as in effect immediately prior to such change.

         SECTION 1.03 CONFLICT IN LOAN DOCUMENTS. If there is any conflict
between this Agreement and any other Loan Document, this Agreement and such
other Loan Document shall be interpreted and construed, if possible, so as to
avoid or minimize such conflict but, to the extent (and only to the extent) of
such conflict, this Agreement shall prevail and control.

         SECTION 1.04 LEGAL REPRESENTATION OF PARTIES. This Agreement and the

or interpretation hereof or thereof.

ARTICLE II. THE CREDIT FACILITY

         SECTION 2.01 THE STANDBY TERM LOAN. (a) Subject to the terms and
conditions of this Agreement and in reliance upon the representations and
warranties of the Borrower contained in Article V, the Lender agrees to make a
standby term loan available to the Borrower on the Closing Date (the "Standby
Term Loan") in the aggregate principal amount not to exceed the Standby Term
Loan Commitment. Advances of the Standby Term Loan (each an "Advance") may be
made during the period (the "Standby Term Loan Period") commencing on the
Closing Date and ending on the earlier to occur of (i) the Borrower's draw of
the entire amount of the Standby Term Loan; or (ii) December 31, 2004. The
Standby Term Loan is a term loan that is non-revolving and the Borrower shall
not have the right to borrow, repay and reborrow under the Standby Term Loan.

         SECTION 2.02 BORROWING PROCEDURES. (a) Requests for Advances. Each
request for an Advance (a "Request for Advance") shall be made by either (i)
delivery by the Borrower to the Lender of an irrevocable written notice in the
form of Exhibit "A" attached hereto signed by a Responsible Officer of the
Borrower (a "Notice of Borrowing"), or (ii) by telephonic notice to the Lender
(confirmed on the same day by a Notice of Borrowing delivered to the Lender),
together with copies of invoices relating to the equipment to be purchased by
the Borrower for which the Advance is requested and such other information as
may reasonably be requested by the Lender. Each Notice of Borrowing shall
constitute the representation and warranty of the Borrower to the Lender that on
the date of such request, and before and after giving effect to the application
of the Advance requested thereby, (i) all representations and warranties set
forth in Article V are true and correct in all material respects as though made
on the date of such request, and (ii) no Potential Default or Event of Default
shall have occurred and be continuing.

                  (b) Prime Rate Tranche Requests. By delivering a Notice of
Borrowing to the Lender or by telephonic notice to the Lender (confirmed on the
same day by a Notice of Borrowing delivered to the Lender), in each case on or
before 10:00 a.m. (prevailing time in Pittsburgh, Pennsylvania) on the requested
Borrowing Date (which must be a Business Day), the Borrower may from time to
time irrevocably request that an Advance be made as a Prime Rate Tranche on the
requested Borrowing Date. On the terms and subject to the conditions of this
Agreement, each such Prime Rate Tranche shall be made available to the Borrower
on the requested Borrowing Date by deposit to the account of the Borrower with
the Lender or by wire transfer in accordance with written instructions as shall
have been delivered to the Lender by the Borrower prior to the making of the
requested Prime Rate Tranche.

                  (c) LIBOR Rate Tranche Requests. By delivering a Notice of
Borrowing to the Lender or by telephonic notice to the Lender (confirmed on the
same day by a Notice of Borrowing delivered to the Lender), in each case on or
before 10:00 a.m. (prevailing time in Pittsburgh, Pennsylvania) on a Business
Day, the Borrower may from time to time irrevocably request, on not less than
two nor more than five (5) Business Days' notice, that an Advance be made as a
LIBOR Rate Tranche in a minimum amount of $500,000 and integral multiples of
$100,000 in excess of such amount and specifying the applicable Interest Period
which shall be one month if the Borrower fails to make such a specification. On
the terms and subject to the conditions of this Agreement, each such LIBOR Rate
Tranche shall be made available to the Borrower on the first day of the
applicable Interest Period by deposit to the account of the Borrower with the
Lender or by wire transfer in accordance with written instructions as shall have
been delivered to the Lender by the Borrower prior to the making of the
requested LIBOR Rate Tranche. After giving effect to all Advances outstanding,
there shall not be more than five (5) LIBOR Rate Tranches outstanding at any
time.

         SECTION 2.03 STANDBY TERM LOAN NOTE. The Standby Term Loan shall be
evidenced by the Standby Term Loan Note, appropriately completed, signed by the
Borrower and dated the Closing Date.

         SECTION 2.04 REPAYMENT OF THE STANDBY TERM LOAN. Interest only shall be
payable from the Closing Date up to but not including January 1, 2005. Subject
to adjustment annually by the Lender in writing to the Borrower to take into
account Hedging Contracts in effect from time to time, commencing on January 1,
2005 and continuing on the first day of each consecutive month thereafter
through and including December 1, 2009, the Borrower shall pay to the Lender
equal and consecutive monthly installments of principal in an amount equal to
1/84th of the outstanding principal balance of the Standby Term Loan on January
1, 2005, and a final principal payment due and payable on the Standby Term Loan
Maturity Date in an amount equal to the then outstanding principal balance of
the Standby Term Loan; provided, during the period(s) that the Standby Term Loan
is classified as a LIBOR Rate Tranche, (i) the Standby Term Loan shall mature
and become payable in full on the last day of each Interest Period, and (ii)
subject to the provisions of Section 2.05(b) regarding continuation and
conversion of outstanding Tranches, upon such maturity, the Standby Term Loan
shall automatically be continued as a LIBOR Rate Tranche with an equal Interest
Period in an amount equal to the expiring LIBOR Rate Tranche LESS the principal
repayments made to the Lender during such the Interest Period applicable to the
expiring LIBOR Rate Tranche, provided, however, that no portion of the
outstanding principal amount of a LIBOR Rate Tranche may be continued as a LIBOR
Rate Tranche when any Event of Default has occurred and is continuing. If any
Event of Default has occurred and is continuing (if the Lender does not
otherwise elect to exercise any right to accelerate the Standby Term Loan it is
granted under this Agreement), the maturing LIBOR Rate Tranche shall
automatically be continued as a Prime Rate Tranche. Notwithstanding the
foregoing, the outstanding principal balance of the Standby Term Loan shall be
due and payable in full on the Standby Term Loan Maturity Date.

         SECTION 2.05 CONTINUATION AND CONVERSION OF TRANCHES. (a) Subject to
the terms and conditions of this Section 2.05, all or a portion of the Standby
Term Loan may be continued or converted into one or more Tranches bearing
interest at the same or different Interest Rate Options as the Borrower may
elect from time to time pursuant to this Section 2.05.

                  (b) By delivering an irrevocable written notice of
continuation/conversion to the Lender in the form of Exhibit "B" attached hereto
(a "Notice of Continuation/Conversion") or by telephonic notice (confirmed on
the same day by a Notice of Continuation/Conversion delivered to the Lender),
the Borrower may irrevocably elect to convert an outstanding Tranche to a
Tranche bearing interest at a different Interest Rate Option or having a
different Interest Period, or continue on the last day of an Interest Period a
Tranche as a Tranche bearing interest at the same Interest Rate Option with a
similar Interest Period, subject to the following conditions:

                           (i) Each Notice of Conversion/Continuation or
         telephonic notice thereof must be received by the Lender (A) not later
         than 10:00 a.m. (prevailing time in Pittsburgh, Pennsylvania) at least
         two (2) Business Days in advance of the date of the requested
         continuation/conversion (the "Continuation/Conversion Date") if the
         Tranche is to be converted into or continued as a LIBOR Rate Tranche,
         and (B) not later than 10:00 a.m. (prevailing time in Pittsburgh,
         Pennsylvania) on the Continuation/Conversion Date if the Tranche is to
         be converted into a Prime Rate Tranche;

                           (ii) A Prime Rate Tranche may be converted into a
         LIBOR Rate Tranche at any time;

                           (iii) A LIBOR Rate Tranche may only be converted to a
         Tranche bearing interest at a different Interest Rate Option or having
         a different Interest Period at the end of the then applicable Interest
         Period therefor;

                                       3
<PAGE>

                           (iv) Any Tranche to be continued as, or converted
         into, a LIBOR Rate Tranche must be in a minimum amount of $500,000 and
         integral multiples of $100,000 in excess of such amount;

                           (v) No portion of a LIBOR Rate Tranche may be
         converted to, or continued as, a LIBOR Rate Tranche when any Potential
         Default or Event of Default has occurred and is continuing;

                           (vi) No portion of a LIBOR Rate Tranche may be
         converted to a LIBOR Rate Tranche of a different duration if such LIBOR
         Rate Tranche relates to any Hedging Obligations; and

                           (vii) There shall be no more than five (5) LIBOR Rate
         Tranches outstanding at any time.

                  (c) If no Interest Rate Option is timely selected at the end
of any Interest Period for a LIBOR Rate Tranche, the Borrower shall be deemed to
have selected a Prime Rate Option for such Tranche. In the absence of a timely
delivery of a Notice of Continuation/Conversion with respect to any LIBOR Rate
Tranche, such Tranche shall, on the last day of the Interest Period relating to
such Tranche, automatically convert to a Prime Rate Tranche.

                  (d) Upon the occurrence and during the continuance of an Event
of Default, any outstanding LIBOR Rate Tranche shall be automatically converted
to a Prime Rate Tranche on the last day of the Interest Period relating thereto
ending during the continuance of such Event of Default.

         SECTION 2.06 REPAYMENTS, PREPAYMENTS, AND INTEREST. (a) Repayments,
Continuations and Conversions. Unless demand has been made prior thereto, LIBOR
Rate Tranches shall mature and become payable in full on the last day of the
Interest Period relating to such LIBOR Rate Tranche. Upon maturity, a LIBOR Rate
Tranche may be continued for an additional Interest Period or may be converted
as permitted under Section 2.05.

                  (b) Voluntary Prepayment of LIBOR Rate Tranches. LIBOR Rate
Tranches may be prepaid upon the terms and conditions set forth herein. For
LIBOR Rate Tranches in connection with which the Borrower has or may incur
Hedging Obligations, additional obligations may be associated with prepayment,
in accordance with the terms and conditions of the applicable Hedging Contracts.
The Borrower shall give the Lender, no later than 10:00 a.m. (prevailing time in
Pittsburgh, Pennsylvania) at least four (4) Business Days notice of any proposed
prepayment of any LIBOR Rate Tranche, specifying the proposed date of payment of
such LIBOR Rate Tranche, and the principal amount to be paid. Each partial
prepayment of the principal amount of a LIBOR Rate Tranche shall be in an
integral multiple of $500,000 and accompanied by the payment of all charges
outstanding on such LIBOR Rate Tranche and of all accrued interest on the
principal repaid to the date of payment. The Borrower acknowledges that
prepayment or acceleration of a LIBOR Rate Tranche during an Interest Period
shall result in the Lender incurring additional costs, expenses and/or
liabilities and that it is extremely difficult and impractical to ascertain the
extent of such costs, expenses and/or liabilities. Therefore, all full or
partial prepayments of LIBOR Rate Tranches shall be accompanied by, and the
Borrower hereby promises to pay, on each date a LIBOR Rate Tranche is prepaid or
the date all sums payable hereunder become due and payable, by acceleration or
otherwise, in addition to all other sums then owing, an amount (the "LIBOR Rate
Prepayment Fee") determined by the Lender pursuant to the following formula:

                           (i) the then current rate for United States Treasury
         securities (bills on a discounted basis shall be converted to a bond
         equivalent) with a maturity date closest to the end of the Interest
         Period as to which prepayment is made, SUBTRACTED FROM

                                       4
<PAGE>

                           (ii) the LIBOR Lending Rate plus the Applicable
         Margin applicable to the LIBOR Rate Tranche being prepaid.

If the result of this calculation is zero or a negative number, then there shall
be no LIBOR Rate Prepayment Fee. If the result of this calculation is a positive
number, then the resulting percentage shall be multiplied by the amount of the
LIBOR Rate Tranche being prepaid, and the resulting amount shall be divided by
360, and multiplied by the number of days remaining in the Interest Period as to
which the prepayment is being made. Said amount shall be reduced to present
value calculated by using the referenced United States Treasury securities rate
and the number of days remaining on the Interest Period for the LIBOR Rate
Tranche being prepaid. The resulting amount of these calculations shall be the
LIBOR Rate Prepayment Fee.

                  (c) Voluntary Prepayment of Prime Rate Tranches. Prime Rate
Tranches may be prepaid at any time without premium or penalty.

         SECTION 2.07 PAYMENTS TO THE LENDER. (a) All payments (including
prepayments) made by the Borrower under this Agreement, the Standby Term Loan
Note or any other Loan Document shall be made in Dollars and in immediately
available funds, without set-off, counterclaim, recoupment or other deduction of
any nature and without presentment, demand, protest or notice of any kind, all
of which are hereby expressly waived by the Borrower, and any action therefor
shall immediately accrue. Except as otherwise expressly provided herein, all
payments by the Borrower shall be made to the Lender at the Lender's Office no
later than 3:00 p.m. (prevailing time in Pittsburgh, Pennsylvania) on the date
specified herein. Any payment received by the Lender later than 3:00 p.m.
(prevailing time in Pittsburgh, Pennsylvania) shall be deemed to have been
received on the following Business Day and any applicable interest or fee shall
continue to accrue. Any payment required to be made by the Borrower to the
Lender under this Agreement or any other Loan Document may, at the Lender's
option, be deducted when due from any deposit or other account (general or
special, time or demand, provisional or final) of the Borrower with the Lender.

                  (b) So long as no Potential Default or Event of Default shall
have occurred and be continuing, payments matching specific scheduled payments
then due will be applied to those scheduled payments. As to each other payment
and all payments made after a Potential Default or Event of Default shall have
occurred and be continuing, the Borrower irrevocably agrees that the Lender
shall have the continuing exclusive right to apply any and all such payments
against such of the Obligations as the Lender may deem advisable in its sole
discretion.

                  (c) The Lender is authorized to, and at its sole election may,
on behalf of the Borrower, charge to the Standby Term Loan balance and cause to
be paid all fees, Reimbursable Costs and Expenses, charges, costs, interest and
principal (other than principal of the Standby Term Loan) owing by the Borrower
under this Agreement or any of the other Loan Documents if and to the extent the
Borrower fails to promptly pay any such amounts as and when due, but it is
expressly acknowledged and agreed that the Lender shall be under no obligation
to do any of the foregoing. At the Lender's option and to the extent permitted
by Law, any charges so made shall constitute part of the Standby Term Loan.

                  (d) Whenever any payment is due on a day other than a Business
Day, such payment shall be made on the following Business Day, and such
extension of time shall in such case be included in the computation of interest
or fees, as the case may be.

                  (e) If the Borrower fails to pay any installment of principal,
interest or other amount under this Agreement within ten (10) days of when due,
in addition to making payment of the installment then due, the Borrower shall
pay to the Lender a late charge in an amount equal to five percent (5.0%) of
such overdue installment.

                                       5
<PAGE>

         SECTION 2.08 LENDER'S RECORDS. The Lender is authorized to record in
its books and records the amount of all loans, advances, repayments, interest
due and paid, and all other charges, fees and expenses paid, or due, and the
like, in connection with this Agreement and the other Loan Documents, and,
except in the case of manifest error in posting or computation, such books and
records shall be presumptively true, correct and binding as to the amounts at
any time due to the Lender from the Borrower under this Agreement and the other
Loan Documents. Any failure so to record or any error in doing so shall not,
however, limit or otherwise affect the obligation of the Borrower hereunder to
pay any amount owing with respect to the Standby Term Loan.

ARTICLE III. INTEREST AND GENERAL LOAN PROVISIONS

         SECTION 3.01 INTEREST. (a) The Standby Term Loan shall bear interest on
the outstanding principal amount thereof for each day until paid (whether by
demand, at stated maturity, by acceleration, or otherwise), as follows:

                           (i) Interest on the outstanding principal amount of
         each LIBOR Rate Tranche shall accrue during the Interest Period
         applicable thereto at a rate per annum equal to the sum of the LIBOR
         Lending Rate for such Interest Period PLUS the Applicable Margin
         thereto (the "LIBOR Rate Option"); and

                           (ii) Interest on the outstanding principal amount of
         each Prime Rate Tranche shall accrue during the Interest Period
         applicable thereto at a rate per annum equal to the sum of the Prime
         Rate for such Interest Period PLUS the Applicable Margin thereto (the
         "Prime Rate Option").

                  (b) If the Lender shall have determined that:

                           (i) US dollar deposits in the relevant amount and for
         the relevant Interest Period are not available to the Lender in the
         London interbank market;

                           (i) by reason of circumstances affecting the Lender
         in the London interbank, adequate means do not exist for ascertaining
         the LIBOR Rate applicable to LIBOR Rate Tranches of any duration; or

                           (iii) the LIBOR Rate no longer adequately reflects
         the Lender's cost of funding the Tranches,

then, upon prior written notice from the Lender to the Borrower, the obligations
of the Lender to make or continue any Tranches as, or to convert any Tranches
into, LIBOR Rate Tranches shall forthwith be suspended until the Lender shall
notify the Borrower that the circumstances causing such suspension no longer
exist; until such notice is delivered, if at all, all Tranches made thereafter
shall be Prime Rate Tranches.

                  (c) Each determination of an interest rate by the Lender shall
be conclusive and binding on the Borrower in the absence of manifest error. At
the request of the Borrower, the Lender will deliver to the Borrower a statement
showing the quotations used by the Lender in determining any interest rate and
the resulting interest rate.

                  (d) Interest on the Standby Term Loan shall be calculated on
the basis of a 360-day year, counting the actual number of days elapsed in the
period during which it accrues. The Borrower shall pay interest on the Standby
Term Loan, in arrears, on each Interest Payment Date, on any date that the
Standby Term Loan is prepaid, at maturity (whether by demand, at stated
maturity, by acceleration, or otherwise), and, during the existence of any Event
of Default, on demand of the Lender. In computing

                                       6
<PAGE>

interest on the Standby Term Loan, the borrowing date or the first day of an
Interest Period applicable to such Tranche or, with respect to a Prime Rate
Tranche being converted from a LIBOR Rate Tranche, the date of conversion of
such LIBOR Rate Tranche to a Prime Rate Tranche, as the case may be, shall be
included, and the date of payment of such Tranche or the expiration date of an
Interest Period applicable to such Tranche or, with respect to a Prime Rate
Tranche being converted to a LIBOR Rate Tranche, the date of conversion of such
Prime Rate Tranche to a LIBOR Rate Tranche, as the case may be, shall be
excluded, provided, that if a Tranche is repaid on the same day on which it is
made, one day's interest shall be paid on that Tranche.

                  (e) Notwithstanding anything to the contrary in this
Agreement, after the occurrence and during the continuance of an Event of
Default or after maturity (whether by demand, stated maturity or otherwise), the
Borrower shall pay interest (after as well as before entry of judgment thereon
to the extent permitted by law) at the following rates:

                           (i) LIBOR Rate Tranches shall bear interest at the
         LIBOR Lending Rate PLUS the highest Applicable Margin for LIBOR Rate
         Tranches PLUS three percent (3.0%), provided, however, that, on and
         after the expiration of any Interest Period applicable to any LIBOR
         Rate Tranche outstanding on the date of occurrence of such Event of
         Default or acceleration, the principal amount of such Tranche shall,
         during the continuation of such Event of Default or after acceleration,
         bear interest at a rate per annum equal to the Prime Rate PLUS the
         highest Applicable Margin for Prime Rate Tranches PLUS three percent
         (3.0%)

                           (ii) Prime Rate Tranches shall bear interest at the
         Prime Rate PLUS the highest Applicable Margin for Prime Rate Tranches
         PLUS three percent (3.0%), and

                           (iii) All other Obligations shall bear interest at
         the Prime Rate PLUS the highest Applicable Margin for Prime Rate
         Tranches PLUS three percent (3.0%).

                  (f) If, at any time, any rate of interest payable hereunder
shall be deemed by any Authority to exceed the maximum rate of interest
permitted by applicable Law, then for such time as such rate would be deemed
excessive, its application shall be suspended and there shall be charged in lieu
thereof the maximum rate of interest permitted under such Law. If any payment of
interest or in the nature of interest would cause the foregoing interest rate
limitation to be exceeded, then such excess payment shall be credited as a
payment of principal, unless the Borrower notifies the Lender to return the
excess payment to the Borrower.

         SECTION 3.02 ILLEGALITY; SUSPENSION OF LIBOR RATE TRANCHES. (a) If the
Lender shall reasonably determine (which determination shall, upon notice
thereof to the Borrower be conclusive and binding on the Borrower) that the
introduction of or any change in or in the interpretation of any Law, rule,
regulation or guideline (whether or not having the force of law) makes it
unlawful, or any central bank or other Authority asserts that it is unlawful,
for the Lender to make, continue or maintain any LIBOR Rate Tranche as, or to
convert any loan into, a LIBOR Rate Tranche of a certain duration, the
obligations of the Lender to make, continue, maintain or convert into any such
LIBOR Rate Tranches shall, upon such determination, forthwith be suspended until
the Lender shall notify the Borrower that the circumstances causing such
suspension no longer exist, and all LIBOR Rate Tranches of such type shall
automatically convert into Prime Rate Tranches at the end of the then current
Interest Periods with respect thereto or sooner, if required by such law or
assertion.

                  (b) If the Lender determines that it is unlawful to maintain
any LIBOR Rate Tranche, the Borrower shall, upon its receipt of notice of such
fact and demand from the Lender, prepay in full such LIBOR Rate Tranches then
outstanding, together with interest accrued thereon and the LIBOR Rate
Prepayment Fee, either on the last day of the Interest Period thereof, if the
Lender may lawfully continue

                                       7
<PAGE>

to maintain such LIBOR Rate Tranches to such day, or immediately, if the Lender
may not lawfully continue to maintain such LIBOR Rate Tranche. If the Borrower
is required to so prepay any LIBOR Rate Tranche, then concurrently with such
prepayment, the Borrower shall borrow a Prime Rate Tranche from the Lender in
the amount of such repayment.

                  (c) If the Lender shall have determined that (i) US dollar
deposits in the relevant amount and for the relevant Interest Period are not
available to the Bank in the London interbank market, (ii) by reason of
circumstances affecting the Lender in the London interbank, adequate means do
not exist for ascertaining the LIBOR Rate applicable hereunder to LIBOR Rate
Tranches of any duration, or (iii) the LIBOR Rate no longer adequately reflects
the Lender's cost of funding loans, then, upon notice from the Lender to the
Borrower, the obligations of the Lender to make or continue any Tranches as, or
to convert any Tranches into, LIBOR Rate Tranches of such duration shall
forthwith be suspended until the Lender shall notify the Borrower that the
circumstances causing such suspension no longer exist.

                  (d) If the obligation of the Lender to make or maintain LIBOR
Rate Tranches has been so terminated or suspended, the Borrower may elect, by
giving notice to the Lender that all Tranches which would otherwise be made by
the Lender as LIBOR Rate Tranches shall instead be made as Prime Rate Tranches.

         SECTION 3.03 INDEMNITIES. In addition to the LIBOR Rate Prepayment Fee,
the Borrower agrees to reimburse the Lender (without duplication) for any
increase in the cost to the Lender, or reduction in the amount of any sum
receivable by the Lender, in respect, or as a result of:

                           (i) any conversion or repayment or prepayment of the
         principal amount of any LIBOR Rate Tranches on a date other than the
         scheduled last day of the Interest Period applicable thereto, whether
         pursuant to Section 3.02 or otherwise;

                           (ii) any Tranches not being made as LIBOR Rate
         Tranches in accordance with the borrowing request thereof;

                           (iii) any LIBOR Rate Tranche not being continued as,
         or converted into, a LIBOR Rate Tranche in accordance with the Notice
         of Continuation/Conversion thereof, or

                           (iv) any costs associated with marking to market any
         Hedging Obligations that (in the reasonable determination of the
         Lender) are required to be terminated as a result of any conversion,
         repayment or prepayment of the principal amount of any LIBOR Rate
         Tranche on a date other than the scheduled last day of the Interest
         Period applicable thereto, whether pursuant to Section 3.02 or
         otherwise.

The Lender shall promptly notify the Borrower in writing of the occurrence of
any such event, such notice to state, in reasonable detail, the reasons therefor
and the additional amount required fully to compensate the Lender for such
increased cost or reduced amount. Such additional amounts shall be payable by
the Borrower to the Lender within five days of its receipt of such notice, and
such notice shall, in the absence of manifest error, be conclusive and binding
on the Borrower. The Borrower understands, agrees and acknowledges the
following: (i) the Lender does not have any obligation to purchase, sell and/or
match funds in connection with the use of LIBOR Rate as a basis for calculating
the rate of interest on a LIBOR Rate Tranche, (ii) the LIBOR Rate may be used
merely as a reference in determining such rate, and (iii) the Borrower has
accepted the LIBOR Rate as a reasonable and fair basis for calculating such
rate, the LIBOR Rate Prepayment Fee, and other funding losses incurred by the
Lender. Borrower further agrees to pay the LIBOR Rate Prepayment Fee and other
funding losses, if any, whether or not the Lender elects to purchase, sell
and/or match funds.

         SECTION 3.04 INCREASED COSTS. If on or after the date hereof the
adoption of any applicable Law, rule or regulation or guideline (whether or not
having the force of law), or any change therein, or any change in the
interpretation or administration thereof by any Authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by the Lender with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency:

                           (i) shall subject the Lender to any tax, duty or
         other charge with respect to its LIBOR Rate Tranches or its obligation
         to make LIBOR Rate Tranches, or shall change the basis of taxation of
         payments to the Lender of the principal of or interest on its LIBOR
         Rate Tranches or any other amounts due under this agreement in respect
         of its LIBOR Rate Tranches or its obligation to make LIBOR Rate
         Tranches (except for the introduction of, or change in the rate of, tax
         on the overall net income of the Lender or franchise taxes, imposed by
         the jurisdiction (or any political subdivision or taxing authority
         thereof) under the laws of which the Lender is organized or in which
         the Lender's principal executive office is located), or

                           (ii) shall impose, modify or deem applicable any
         reserve, special deposit or similar requirement (including, without
         limitation, any such requirement imposed by the Board of Governors of
         the Federal Reserve System of the United States) against assets of,
         deposits with or for the account of, or credit extended by, the Lender
         or shall impose on the Lender or on the London interbank market any
         other condition affecting its LIBOR Rate Tranches or its obligation to
         make LIBOR Rate Tranches,

and the result of any of the foregoing is to increase the cost to the Lender of
making or maintaining any LIBOR Rate Tranche, or to reduce the amount of any sum
received or receivable by the Lender under this Agreement with respect thereto,
by an amount deemed by the Lender to be material, then, within 15 days after
demand by the Lender, the Borrower shall pay to the Lender such additional
amount or amounts as will compensate the Lender for such increased cost or
reduction.

         SECTION 3.05 INCREASED CAPITAL COSTS. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any Law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other Authority affects or would affect the amount of capital required or
expected to be maintained by the Lender, or person controlling the Lender, and
the Lender determines (in its sole and absolute discretion) that the rate of
return on its or such controlling person's capital as a consequence of its
commitments or the loans made by the Lender is reduced to a level below that
which the Lender or such controlling person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by the Lender to the Borrower, the Borrower shall immediately pay
directly to the Lender additional amounts sufficient to compensate the Lender or
such controlling person for such reduction in rate of return. A statement of the
Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrower. In determining such amount, the Lender
may use any reasonable method of averaging and attribution that it reasonably
shall deem applicable.

         SECTION 3.06 TAXES. (a) All payments by the Borrower of principal of,
and interest on, the LIBOR Rate Tranches and all other amounts payable hereunder
shall be made free and clear of and without deduction for any present or future
income, excise, stamp or franchise taxes and other taxes, assessments, imposts,
duties, deductions, fees, withholdings or similar charges, and all liabilities
with respect thereto of any nature whatsoever imposed by any taxing authority,
but excluding franchise taxes and taxes imposed on or measured by the Lender's
net income or receipts (such non-excluded items being called "Taxes"). In the
event that any withholding or deduction from any payment to be made by the

                                       9
<PAGE>

Borrower hereunder is required in respect of any Taxes pursuant to any
applicable law, rule or regulation, then the Borrower will

                           (i) pay directly to the relevant authority the full
         amount required to be so withheld or deducted;

                           (ii) promptly forward to the Lender an official
         receipt or other documentation satisfactory to the Lender evidencing
         such payment to such authority; and

                           (iii) pay to the Lender such additional amount or
         amounts as is necessary to ensure that the net amount actually received
         by the Lender will equal the full amount the Lender would have received
         had no such withholding or deduction been required.

                  (b) If any Taxes are directly asserted against the Lender with
respect to any payment received by the Lender hereunder, the Lender may pay such
Taxes and the Borrower will promptly pay such additional amount (including any
penalties, interest or expenses) as is necessary in order that the net amount
received by the Lender after the payment of such Taxes (including any Taxes on
such additional amount) shall equal the amount the Lender would have received
had not such Taxes been asserted.

                  (c) If the Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to the Lender the required
receipts or other required documentary evidence, the Borrower shall indemnify
the Lender for any incremental Taxes, interest or penalties that may become
payable by the Lender as a result of any such failure.

         SECTION 3.07 SURVIVAL. The agreements and obligations of the Borrower
in this Article III shall survive the payment of all other Obligations.

         SECTION 3.08 SECURITY. The prompt and full satisfaction of the
Obligations shall be secured by the Collateral Documents.

the issuance of any securities convertible or exchangeable, actually or
contingently, into partnership interests of the Borrower or Superior.

         SECTION 5.06 ADVERSE OCCURRENCES. No event or events have occurred
which, individually or in the aggregate, have had, or could reasonably be
expected to have, a Material Adverse Effect. No Event of Default exists or would
result from the incurring of any obligations by the Loan Parties under the Loan
Documents or from the grant or perfection of the Liens on the Collateral in
favor of the Lender.

<PAGE>

of all other personal property). All such properties and assets are free and
clear of all Liens except Permitted Liens.

                  (b) Schedule 5.09 attached hereto lists all insurance policies
and other bonds to which the Borrower or Superior is a party, all of which are
valid and in full force and effect. No notice has been given or claim made and
no grounds exist to cancel or avoid any of such policies or bonds or to reduce
the coverage provided thereby. Such policies and bonds provide adequate coverage
from reputable and financially sound insurers in amounts sufficient to insure
the assets and risks of the Borrower and Superior in accordance with prudent
business practice in the industry of the Borrower.

         SECTION 5.10 CONTRACTUAL OBLIGATIONS AND EQUIPMENT LEASES. (a) The
Borrower and Superior are in compliance with the provisions of all contracts,
licenses, instruments and other commitments of any kind material to the
financial condition, properties, assets or prospects of the Borrower and
Superior, and no event has occurred which, but for the passage of time or the
giving of notice, or both, would constitute a default thereunder except to the
extent that such failure to comply or such default could not reasonably be
expected to have in a Material Adverse Effect. Neither the Borrower nor Superior
is a party to or otherwise subject to any agreements or instruments or any
charter or other internal restrictions which, individually or in the aggregate,
compliance with which could reasonably be expected to have a Material Adverse
Effect.

                  (b) Schedule 5.10 attached hereto contains a complete list of
the amounts owing, due dates and other information with respect to all equipment
leased by the Borrower to Superior together with a description (including
identification and serial numbers, if applicable) of all of such equipment, and
the same are and will be correctly stated in all records of the Borrower. The
Borrower has delivered to the lender true and correct copies of the Equipment
Lease and all of its other equipment leases (including all amendments, exhibits
and schedules thereto), which are in full force and effect on the Closing Date.
All action by the Borrower necessary or desirable to protect and perfect the
Lender's Liens on the Equipment Lease has been duly taken. No event has occurred
which, but for the passage of time or the giving of notice, or both, would
constitute a default under the Equipment Lease.

         SECTION 5.11 TAXES. All tax returns required to be filed by the
Borrower and the other Loan Parties have been properly prepared, executed and
filed. All taxes, assessments, fees and other governmental charges upon the
Borrower and the other Loan Parties or upon any of their properties, income,
sales or franchises that are due and payable have been paid. The Borrower does
not know of any proposed additional assessment or basis for any material
assessment for additional taxes against the Borrower and the other Loan Parties
(whether or not reserved against by the Borrower and the other Loan Parties)
that would be material to the condition (financial or otherwise) of the Borrower
and the other Loan Parties. All tax liabilities of the Borrower and the other
Loan Parties are adequately provided for on the books of the Borrower and the
other Loan Parties.

         SECTION 5.12 MARGIN STOCK; INVESTMENT COMPANY. None of the proceeds of
the Standby Term Loan will be used by the Borrower for the purpose of buying or
carrying any margin stock ("Margin Stock") as such term is defined in Regulation
U, Regulation X or Regulation G promulgated by the Board of Governors of the
Federal Reserve System, as amended from time to time, or to reduce or retire any
loan or advance incurred to purchase or carry Margin Stock. The Borrower is not
and will not become engaged in the business of extending credit for the purpose
of buying or carrying Margin Stock, and no part of the proceeds of any borrowing
hereunder will be used to extend credit to others for the purpose of purchasing
or carrying any Margin Stock. The Borrower is not, nor will it become, an
"investment company" or a company "controlled" by an "investment company", as
each of such terms are defined in the Investment Company Act of 1940, as
amended. The Borrower is not subject to regulation under the Public Utility
Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce Act,
any state public utilities code, or any other Federal or state statute or
regulation limiting its ability to incur Indebtedness.

licenses, permits and franchises, and all rights in respect of the foregoing
required to conduct its business as now conducted, or as presently contemplated
to be conducted, without any conflict with, or infringement upon rights of,
other Persons, and the Borrower is not in violation of any valid rights of
others with respect to any of the foregoing.

         SECTION 5.14 ENVIRONMENTAL LAWS. (a) The Borrower, Superior and their
Environmental Affiliates are and have been in compliance with all applicable
Environmental Laws, except for such non-compliance which, individually or in the
aggregate, has not, and reasonably could not be expected to have, a Material
Adverse Effect. To the knowledge of the Borrower and Superior, there are no
circumstances that may prevent or interfere with such compliance in the future.

                  (b) Neither the Borrower nor Superior has received any notice
to the effect that its operations are not in material compliance with any of the
requirements of applicable Environmental Laws or are the subject of any federal
or state investigation evaluating whether any remedial action is needed to
respond to a release of any Hazardous Materials or substance into the
environment, which non-compliance or remedial action could reasonably be
expected to have a Material Adverse Effect.

         SECTION 5.15 COLLATERAL DOCUMENTS. The provisions of the Collateral
Documents executed or to be executed by the Loan Parties in favor of the Lender
will be, on and after the due execution and delivery thereof, effective to
create, for the benefit of the Lender, legal, valid and enforceable Liens in all
of the Collateral described therein, securing the Standby Term Loan Note and all
other Obligations from time to time outstanding.

         SECTION 5.16 BANKRUPTCY; INSOLVENCY. None of the Loan Parties has
applied for or consented to the appointment of a receiver, trustee, custodian or
liquidator for itself or any of its properties, admitted in writing its
inability to pay its debts as they mature, made a general assignment for the
benefit of creditors, been adjudicated a bankrupt or insolvent or filed a
voluntary petition in bankruptcy, or a petition or an answer seeking
reorganization or an arrangement with creditors or to take advantage of any
bankruptcy, reorganization, insolvency, readjustment of debt, dissolution or
liquidation law or statute, or an answer admitting the material allegations of a
petition filed against it in any proceeding under any such law, and no action
has been taken by the Borrower or any of the other Loan Parties for the purposes
of effecting any of the foregoing.

         SECTION 5.17 COMPLIANCE WITH LAWS. Neither the operation of the
business of the Borrower or any of the other Loan Parties nor the development,
manufacture, assembly or sale of the products or services of the Borrower or any
of the other Loan Parties violate any Law applicable to the Loan Parties, except
to the extent that any such violation has not, and reasonably could not be
expected to have, a Material Adverse Effect.

         SECTION 5.18 LOCATIONS. Schedule 5.18 attached hereto sets forth the
location of (i) the chief executive office of the Borrower and Superior, (ii)
the office where the Borrower and Superior keep their records concerning the

otherwise) to such locations.

         SECTION 5.19 ERISA PLANS. Except as disclosed in Schedule 5.19:

                           (i) Each Plan is in compliance in all material
         respects with the applicable provisions of ERISA, the Code and other
         federal or state law. Each Plan which is intended to qualify under
         Section 401(a) of the Code has received a favorable determination
         letter from the IRS and to the best knowledge of the Borrower, nothing
         has

                                       15
<PAGE>

         occurred which would cause the loss of such qualification. The
         Borrower and each ERISA Affiliate has made all required contributions
         to any Plan subject to Section 412 of the Code, and no application for
         a funding waiver or an extension of any amortization period pursuant to
         Section 412 of the Code has been made with respect to any Plan;

                           (ii) There are no pending or, to the knowledge of the
         Borrower, threatened claims, actions or lawsuits, or action by any
         Authority, with respect to any Plan that has or could reasonably be
         expected to have a Material Adverse Effect. There has been no
         prohibited transaction or violation of the fiduciary responsibility
         rules with respect to any Plan which has or could reasonably be
         expected to have a Material Adverse Effect; and

                           (iii) (A) No ERISA Event has occurred or is
         reasonably expected to occur; (B) no Pension Plan has any Unfunded
         Pension Liability; (C) neither the Borrower nor any ERISA Affiliate has
         incurred, or reasonably expects to incur, any liability under Title IV
         of ERISA with respect to any Pension Plan (other than premiums due and
         not delinquent under Section 4007 of ERISA); (D) neither the Borrower
         nor any ERISA Affiliate has incurred, or reasonably expects to incur,
         any liability (and no event has occurred which, with the giving of
         notice under Section 4219 of ERISA, would result in such liability)
         under Section 4201 or 4243 of ERISA with respect to a Multiemployer
         Plan; and (E) neither the Borrower nor any ERISA Affiliate has engaged
         in a transaction that could be subject to Section 4069 or 4212(c) of
         ERISA.

         SECTION 5.20 CONTEMPORANEOUS EXCHANGE. The attachment and perfection of
the security interests in the Collateral effected on the Closing Date by virtue
of the Collateral Documents executed and delivered pursuant to this Agreement
are intended to be a contemporaneous exchange for new value given by virtue of
the consummation of the transactions contemplated by this Agreement and are, in
fact, a substantially contemporaneous exchange for such new value.

         SECTION 5.21 DISCLOSURE. No representation or warranty made by the Loan
Parties in the Loan Documents, no statement made or to be made by the Loan
Parties in any financial information, certificate, report, exhibit or document
furnished or to be furnished by the Loan Parties to the Lender pursuant to or in
connection herewith or therewith contains or will contain any untrue material
statement or omits or will omit to state any material fact necessary to make the
statements contained therein not misleading in light of the circumstances under
which they were made. The Borrower has made full and true disclosure of all
information known to the Borrower, financial or otherwise, relating to the Loan
Parties or in connection with the transactions contemplated hereby which has
resulted, or which could reasonably be expected to result, in a Material Adverse
Effect.

         claims of materialmen, mechanics, carriers, warehousemen, landlords and
         other like Persons that, if unpaid, might result in the creation of a
         Lien upon any property of the Borrower or Superior;

                           (ii) on or prior to the date when due, all other

of the circumstances that existed at the time such statement was made.

         SECTION 6.14 SECURITY INTERESTS. (a) The Borrower and Superior will
defend the Collateral owned by it against all claims and demands of all Persons
at any time claiming the same or any interest therein. The Borrower and Superior
will comply with the requirements of all state and federal laws in order to
grant to the Lender valid and perfected first priority security interests in the
Collateral owned by it, subject to Permitted Liens. The Borrower and Superior
hereby irrevocably authorize the Lender at any

                                       22
<PAGE>

time and from time to time to file in any jurisdiction any initial financing
statements, amendments thereto and continuations thereof describing or relating
to the Collateral. The Borrower and Superior agree to furnish any such
information to the Lender promptly upon request. The Borrower and Superior also
ratify their authorization for the Lender to have filed in any jurisdiction any
like initial financing statements or amendments thereto if filed prior to the
Closing Date.

                  (b) The Borrower and Superior shall use their best efforts to
obtain a landlord's agreement, mortgagee agreement or bailee letter, as
applicable, from the lessor of each leased property or mortgagee of owned
property or with respect to any warehouse, processor or other location where
Collateral is located, which agreement or letter shall contain a waiver or
subordination of all Liens or claims that the landlord, mortgagee or bailee may
assert against the Collateral at that location, and shall otherwise be
satisfactory in form and substance to the Lender (each such agreement or letter
being a "Collateral Access Agreement"). After the Closing Date, no real property
or warehouse space shall be leased or acquired by the Borrower unless the
Borrower shall have first used its best efforts to obtain a Collateral Access
Agreement with respect to such location and all other terms and conditions of
this Agreement with respect to the Collateral shall have been complied with.

         SECTION 6.15 FURTHER ASSURANCES. (a) Promptly upon request by the
Lender, the Borrower and Superior will take such further actions and execute,
acknowledge, deliver, record, re-record, file, re-file, register and
re-register, any and all such further, security agreements, mortgages,
assignments, estoppel certificates, financing statements and continuations
thereof, termination statements, notices of assignment, transfers, certificates,
assurances and other instruments the Lender may reasonably require from time to
time in order to (i) subject to the Liens created by any of the Collateral
Documents any of the properties, rights or interests covered by any of the
Collateral Documents, (ii) perfect and maintain the validity, effectiveness and
priority of any of the Collateral Documents and the Liens intended to be created
thereby, and (iii) better assure, convey, grant, assign, transfer, preserve,
protect and confirm to the Lender the rights granted or now or hereafter
intended to be granted to the Lender under any Loan Document or under any other
document executed in connection therewith. The Borrower and Superior further
agree that a carbon, photographic, facsimile or other reproduction of any
financing statement or the Collateral Documents shall be sufficient as a
financing statement and amendments, renewals and continuations thereof, and may
be filed as such. THE BORROWER AND SUPERIOR AUTHORIZE THE LENDER TO FILE AND
RECORD, AND FURTHER IRREVOCABLY APPOINT THE LENDER, ITS AGENTS AND EMPLOYEES, AS
ITS ATTORNEY-IN-FACT TO EXECUTE, DELIVER, FILE AND RECORD IN THE NAME OF THE
BORROWER AND SUPERIOR, ANY FINANCING STATEMENTS OR ANY OF THE OTHER
AFOREMENTIONED ITEMS AT ANY TIME AFTER THE BORROWER OR SUPERIOR HAS FAILED TO
DELIVER THE SAME TO THE LENDER AFTER REQUEST THEREFOR BY THE LENDER. The
Borrower and Superior acknowledge that the provisions of 20 Pa.C.S. Section 5601
shall not apply to the foregoing power of attorney granted to the Lender.

                  (b) The Borrower and Superior will provide such additional
documents, and perform such additional acts, as the Lender may reasonably deem
necessary to effectively carry out the purposes of, or to confirm, this
Agreement, the Collateral Documents and the other Loan Documents, or to enable
the Lender to enforce any of rights hereunder or thereunder.

                           (i) If the Event of Default that has occurred is an
         Event of Default other than those specified in Section 8.05, then the
         Lender may (A) declare the Standby Term Loan Commitment to be
         terminated, and the Lender shall have no further obligation to make
         Advances, and (B) declare the unpaid principal amount of the Standby
         Term Loan, interest accrued thereon and all other Obligations to be
         immediately due and payable without presentment, demand, protest or
         further notice or act of any kind, all of which are hereby expressly
         waived by the Borrower, and an action therefor shall immediately
         accrue;

                           (ii) If the Event of Default that has occurred is an
         Event of Default specified in Section 8.05, then (A) the Standby Term

                                       29
<PAGE>

         accrued thereon and all other Obligations shall automatically become
         due and payable without presentment, demand, protest or further act or
         notice of the Lender of any kind, all of which are hereby expressly
         waived by the Borrower, and an action therefor shall immediately
         accrue;

                           (iii) With respect to the Collateral, the Lender
         shall have all of the rights and remedies of a secured party or
         otherwise afforded to it by Law and such additional rights and remedies
         as are contained in the Loan Documents;

                           (iv) At any time after ten (10) days' prior written
         notice from the Lender to the Borrower of its intention to apply for a
         receiver, the Lender shall be entitled to apply for and have a receiver
         appointed under state or federal law by a court of competent
         jurisdiction in any action taken by the Lender to enforce the Lender's
         rights and remedies under this Agreement, the Collateral Documents and
         the other Loan Documents in order to protect, preserve, manage, sell
         and otherwise dispose of all or any portion of the Collateral and
         continue the operation of the business of the Borrower and to collect
         all revenues and profits thereof and apply the same to the payment of
         all expenses and other charges of such receivership, including the
         compensation of the receiver, and to the payment of the Standby Term
         Loan and other Reimbursable Costs and Expenses due hereunder and under
         the Loan Documents until a sale or other disposition of such
         Collateral. TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER
         KNOWINGLY, INTENTIONALLY, VOLUNTARILY AND, ON THE ADVICE OF SEPARATE
         COUNSEL OF THE BORROWER, IRREVOCABLY CONSENTS TO AND WAIVES ANY RIGHT
         TO OBJECT TO OR OTHERWISE CONTEST THE APPOINTMENT OF A RECEIVER AS
         PROVIDED FOR HEREIN. THE BORROWER ACKNOWLEDGES THAT (i) RIGHT TO HAVE A
         RECEIVER APPOINTED WITHOUT CONTEST IS VERY IMPORTANT TO THE LENDER IN
         CONNECTION WITH THE ENFORCEMENT OF THE LENDER'S RIGHTS AND REMEDIES
         UNDER THIS AGREEMENT, THE COLLATERAL DOCUMENTS AND THE OTHER LOAN
         DOCUMENTS, AND (ii) THE AVAILABILITY OF SUCH APPOINTMENT AS A REMEDY
         WAS A MATERIAL INDUCEMENT TO THE LENDER TO ENTER INTO THIS AGREEMENT
         AND MAKE THE STANDBY TERM LOAN AVAILABLE TO THE BORROWER. THE BORROWER
         AGREES TO ENTER INTO ANY AND ALL STIPULATIONS IN ANY LEGAL ACTIONS, OR
         AGREEMENTS OR OTHER INSTRUMENTS IN CONNECTION WITH THE FOREGOING AND TO
         COOPERATE FULLY WITH THE LENDER IN CONNECTION WITH THE ASSUMPTION AND
         EXERCISE OF CONTROL BY THE RECEIVER OVER ALL OR ANY PORTION OF THE
         COLLATERAL;

                           (v) In addition to any rights and remedies of the
         Lender provided by Law, the Lender is authorized at any time and from
         time to time, without prior notice to the Borrower, any such notice
         being waived by the Borrower to the fullest extent permitted by law, to
         set off and apply any and all deposits (general or special, time or
         demand, provisional or final) at any time held by, and other
         Indebtedness at any time owing by, the Lender to or for the credit or
         the account of the Borrower against any and all Obligations owing to
         the Lender, now or hereafter existing, irrespective of whether or not
         the Lender shall have made demand under this Agreement or any Loan
         Document and although such Obligations may be contingent or unmatured.
         The Lender agrees promptly to notify the Borrower after any such
         set-off and application made by the Lender; provided, however, that the
         failure to give such notice shall not affect the validity of such
         set-off and application; and

                           (vi) The following paragraph sets forth a warrant of
         authority for an attorney to confess judgment against the Borrower. In
         granting this warrant to confess judgment, the Borrower hereby
         knowingly, intentionally, voluntarily and, on the advice of separate
         counsel of the Borrower, unconditionally waives any and all rights the
         Borrower has or may have to prior notice and an opportunity for hearing
         before a judgment can be entered hereunder:

                                       30
<PAGE>

                  THE BORROWER UNCONDITIONALLY AND IRREVOCABLY AUTHORIZES AND
         EMPOWERS ANY ATTORNEY OR ANY PROTHONOTARY, CLERK OF COURT OR COURT OF
         RECORD, AS ATTORNEY FOR THE BORROWER, TO APPEAR FOR THE BORROWER IN
         SUCH COURT AT ANY TIME AFTER THE OCCURRENCE OF AN EVENT OF DEFAULT AND
         CONFESS JUDGMENT AGAINST THE BORROWER IN FAVOR OF THE LENDER FOR (i)
         POSSESSION OF ANY OF THE COLLATERAL IN ANY ACTION FOR REPLEVIN
         INSTITUTED BY THE LENDER, AND (ii) FOR ALL OR ANY PORTION OF THE
         OUTSTANDING BALANCE OF THE OBLIGATIONS (INCLUDING WITHOUT LIMITATION,
         THE OUTSTANDING PRINCIPAL BALANCE OF THE TERM LOAN), TOGETHER WITH
         UNPAID INTEREST, COSTS OF SUIT AND ATTORNEYS' FEES ADDED FOR COLLECTION
         IN AN AMOUNT EQUAL TO THE GREATER OF FIVE PERCENT (5.0%) OF THE SUM DUE
         OR $15,000. THE BORROWER ALSO RELEASES ALL ERRORS, AND TO THE EXTENT
         PERMITTED BY LAW, WAIVES AND RELEASES ALL RELIEF FROM ANY AND ALL
         APPRAISEMENT, STAY OR EXEMPTION LAW OF ANY STATE NOW IN FORCE OR
         HEREAFTER ENACTED. IF A COPY OF THIS AGREEMENT, VERIFIED BY AFFIDAVIT
         OF THE LENDER OR SOMEONE ON BEHALF OF THE LENDER, SHALL HAVE BEEN FILED
         IN SUCH ACTION, IT SHALL NOT BE NECESSARY TO FILE AN ORIGINAL OF THIS
         AGREEMENT AS A WARRANT OF ATTORNEY. THE AUTHORITY AND POWER TO APPEAR
         FOR AND ENTER JUDGMENT AGAINST THE BORROWER SHALL NOT BE EXHAUSTED BY
         THE INITIAL EXERCISE THEREOF OR BY ANY IMPERFECT EXERCISE THEREOF AND
         SHALL NOT BE EXTINGUISHED BY ANY JUDGMENT ENTERED PURSUANT THERETO; THE
         AUTHORITY AND POWER MAY BE EXERCISED ON ONE OR MORE OCCASIONS, FROM
         TIME TO TIME, IN THE SAME OR DIFFERENT JURISDICTIONS, AS OFTEN AS THE
         LENDER SHALL DEEM NECESSARY OR DESIRABLE, FOR ALL OF WHICH THIS
         AGREEMENT OR A VERIFIED COPY HEREOF SHALL BE A SUFFICIENT WARRANT. TO
         THE EXTENT PERMITTED BY LAW, INTEREST SHALL ACCRUE ON ANY JUDGMENT AT
         THE DEFAULT RATE APPLICABLE TO THE PRIME RATE TRANCHES.

         SECTION 9.02 CUMULATIVE REMEDIES. The rights, remedies and powers of
the Lender under this Agreement and the other Loan Documents are cumulative,
irrevocable and non-exclusive of any rights, remedies or powers which the Lender
would otherwise have, including, without limitation, the right of specific
performance.

         SECTION 9.03 WAIVER OF RIGHT TO MARSHAL. Each of the Borrower, the
General Partner and Superior for itself and all who may claim through or under
it, hereby expressly waives and releases all rights to have the Collateral, or
any part thereof, or any other of its properties, marshaled on any foreclosure,
sale or other enforcement thereof, and the Lender, or any court in which the
foreclosure of the liens or security interests in the Collateral are sought,
shall have the right as aforesaid to sell the Collateral as an entirety in a
single parcel. The Borrower, the General Partner and Superior upon the request
of the Lender, shall provide the Lender with a specific written waiver to
evidence the intent of this Section 9.03.

ARTICLE X. MISCELLANEOUS

         SECTION 10.01 AUTOMATIC DEBITS OF FEES. With respect to any commitment
or other fee, or any other cost or expense (including attorneys' fees) due and
payable to the Lender under the Loan Documents, the Borrower hereby irrevocably
authorizes the Lender to debit any deposit account of the Borrower with the
Lender in an amount such that the aggregate amount debited from all such deposit
accounts does not exceed such fee or other cost or expense. If there are
insufficient funds in such deposit accounts to cover the amount of the fee or
other cost or expense then due, such debits will be reversed (in whole or in
part, in the Lender's sole discretion) and such amount not debited shall be
deemed to be unpaid. No such debit under this Section shall be deemed a set-off.

         SECTION 10.02 RIGHTS IN PROPERTY HELD BY THE LENDER. As security for
the prompt and full satisfaction of the Obligations, the Borrower hereby
assigns, transfers and sets over to each Lender all of its right, title and
interest in and to, and grants the Lender a lien on and security interest in,
all amounts that may be owing from time to time by the Lender to the Borrower in
any capacity, including, without limitation, any balance or share belonging to
the Borrower of any deposit or other account with the Lender (general or
special, time or demand, provisional or final), which lien and security interest
shall be independent of any right of set-off which the Lender may have
otherwise.

         SECTION 10.03 COLLATERAL. All Collateral of any kind held by the Lender
shall stand as one general, continuing collateral security for the Obligations
and all other liabilities and Indebtedness now existing or hereafter incurred by
the Borrower to the Lender, and may be retained by the Lender until all of such
Obligations have been paid in full.

         SECTION 10.04 NO THIRD PARTY RIGHTS. Nothing in this Agreement, whether
expressed or implied, shall be construed to give to any Person other than the
parties hereto any legal or equitable right, remedy or claim under or in respect
of this Agreement, it being expressly understood that this Agreement is intended
for the sole protection and legal benefit of the Borrower, the Lender and their
permitted successors and assigns, and no other Person shall be a direct or
indirect legal beneficiary of, or have any direct or indirect cause of action or
claim in connection with, this Agreement or any of the other Loan Documents.

         SECTION 10.05 CONSTRUCTION. The provisions of this Agreement shall be
in addition to those of the other Loan Documents, all of which shall be
construed as complementing each other and as augmenting and not restricting the
rights of the Lender. Nothing herein contained shall prevent the Lender from
enforcing, in accordance with their respective terms, any of the Loan Documents
on a several basis. In no event shall the rights of the Lender hereunder and
under the other Loan Documents be construed to grant the Lender the right to, or
be deemed to indicate that, the Lender is in control of the business, management
or properties of the Borrower or have power over the daily management functions
and operating decisions made by the Borrower. To the extent any provision of
this Agreement or the other Loan Documents shall be held to be in violation of
any applicable Law, then the Lender shall not be required, to the extent of such
violation, to perform its obligations in connection with such provision.

         SECTION 10.06 WAIVER. No course of dealing and no failure or delay on
the part of the Lender to exercise any right, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege preclude any other or further exercise
of any other right, power or privilege.

         SECTION 10.07 INDEMNIFICATION BY THE BORROWER. (a) Whether or not the
transactions contemplated hereby are consummated, the Borrower shall indemnify,
defend and hold the Lender and its officers, directors, employees, counsel,
agents and attorneys-in-fact (each, an "Indemnified Person") harmless from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, charges, expenses and disbursements (including
reasonable attorneys' fees) of any

                                       32
<PAGE>

kind or nature whatsoever which may at any time (including at any time following
repayment of the Standby Term Loan) be imposed on, incurred by or asserted
against any such Person in any way relating to or arising out of this Agreement
or any document contemplated by or referred to herein, or the transactions
contemplated hereby, or any action taken or omitted by any such Person under or
in connection with any of the foregoing, including with respect to any
investigation, litigation or proceeding (including any Insolvency Proceeding or
appellate proceeding) related to or arising out of this Agreement or the Standby
Term Loan or the use of the proceeds thereof, whether or not any Indemnified
Person is a party thereto (all the foregoing, collectively, the "Indemnified
Liabilities"); provided, that the Borrower shall have no obligation hereunder to
any Indemnified Person with respect to Indemnified Liabilities resulting solely
from the gross negligence or willful misconduct of such Indemnified Person. The
agreements in this Section shall survive payment of all other obligations.

                  (b) The Borrower shall indemnify, defend and hold harmless
each Indemnified Person, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, charges, expenses
or disbursements (including reasonable attorneys' fees and the allocated cost of
internal environmental audit or review services), which may be incurred by or
asserted against such Indemnified Person in connection with or arising out of
any pending or threatened investigation, litigation or proceeding, or any action
taken by any Person, with respect to any Environmental Claim arising out of or
related to any property subject to a mortgage or deed of trust in favor of the
Lender except to the extent resulting solely from the gross negligence or
willful misconduct of such Indemnified Person. In no event shall any site visit,
observation, or testing by the Lender (or any contractee of the Lender) be
deemed a representation or warranty that Environmental Concern Materials are or
are not present in, on, or under, the site, or that there has been or shall be
compliance with any Environmental Law. Neither the Borrower nor any other Person
is entitled to rely on any site visit, observation, or testing by the Lender.
The Lender owes no duty of care to protect the Borrower or any other Person
against, or to inform the Borrower or any other party of, any Environmental
Concern Materials or any other adverse condition affecting any site or property.

                  (c) The obligations in this Section shall survive payment of
all other Obligations. At the election of any Indemnified Person, the Borrower
shall defend such Indemnified Person using legal counsel satisfactory to such
Indemnified Person in such Person's sole discretion, at the sole cost and
expense of the Borrower. All amounts owing under this Section shall be paid
within thirty (30) days after demand.

         SECTION 10.08 PAYMENTS SET ASIDE. To the extent that the Borrower makes
a payment to the Lender, or the Lender exercises its right of set-off, and such
payment or the proceeds of such set-off or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Lender in its
discretion) to be repaid to a trustee, receiver or any other party, in
connection with any Insolvency Proceeding or otherwise, then to the extent of
such recovery the obligation or part thereof originally intended to be satisfied
shall be revived and continued in full force and effect as if such payment had
not been made or such set-off had not occurred.

         SECTION 10.09 WAIVER OF JURY TRIAL. THE BORROWER AND THE LENDER HEREBY
EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY OR ANY CLAIM, DEMAND, ACTION OR CAUSE
OF ACTION (I) ARISING UNDER THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR ANY OTHER
DOCUMENT OR INSTRUMENT ATTACHED HERETO, REFERRED TO HEREIN OR DELIVERED IN
CONNECTION HEREWITH, OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL
TO THE DEALINGS OF THE BORROWER WITH RESPECT TO THIS AGREEMENT, ANY OTHER LOAN
DOCUMENT OR INSTRUMENT ATTACHED HERETO, REFERRED TO HEREIN OR DELIVERED IN
CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE
WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND THE BORROWER AND THE

                                       33
<PAGE>

LENDER HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF
ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO
THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH
ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF BORROWER AND THE LENDER HERETO
TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

         SECTION 10.10 CONSENT TO JURISDICTION. The Borrower and the Lender
hereby irrevocably consent and agree that any action or proceeding against it
may be commenced and maintained in any state court sitting in Allegheny County,
Pennsylvania or in the United States District Court for the Western District of
Pennsylvania, and each waive personal service of any summons, complaint or other
process, which may be made by any other means permitted by Pennsylvania. The
Borrower irrevocably consents and agrees that the state courts sitting in
Allegheny County, Pennsylvania and the United States District Court for the
Western District of Pennsylvania shall have exclusive jurisdiction for any
action or proceeding commenced by or through it with respect to the subject
matter hereof. THE BORROWER AND THE LENDER EACH IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS
AGREEMENT OR ANY DOCUMENT RELATED HERETO.

         SECTION 10.11 SURVIVAL. All representations and warranties of the
Borrower contained herein or made in connection herewith are continuing and
shall survive the making of and shall not be waived by the execution and
delivery of the Loan Documents, the making of the Standby Term Loan.
Notwithstanding termination of this Agreement or the occurrence of an Event of
Default, all covenants and agreements of the Borrower shall continue in full
force and effect from and after the date of this Agreement until payment in full
of the Standby Term Loan, all interest accrued thereon and all other sums due
under the Loan Documents.

         SECTION 10.12 DISCLOSURE OF INFORMATION. So long as no Event of Default
has occurred and is continuing, the Lender shall hold all information obtained
from the Borrower pursuant to or in connection with this Agreement in confidence
in accordance with its customary practices for handling information of the
nature received from the Borrower and in accordance with safe and sound lending
practices, but in any event, the Lender may disclose any information concerning
the Borrower in its possession (i) upon the order of any court or administrative
agency, (ii) pursuant to any subpoena or other legal process, or in connection
with any litigation, (iii) upon the request or demand of any regulatory agency
or other Authority having jurisdiction over the Lender, (iv) which has been
publicly disclosed, (v) which has been obtained from any Person that is not a
party hereto provided such Person did not obtain such information in violation
of any confidentiality agreement binding on such Person, (vi) to the extent
required in connection with the exercise of any remedy under the Loan Documents
or to protect the Lender's rights under the Loan Documents or in and to the
Collateral, (vii) to the Lender's legal counsel, its regulators, affiliates,
outside auditors and other professional advisors, provided such Persons agree to
be bound by the provisions of this Section, (viii) to any other Person to whom
the Lender grants or proposes to grant a participation in or assignment or other
transfer of all or any part of the Standby Term Loan or other Obligations,
provided such Persons agree to be bound by the provisions of this Section. The
Lender shall endeavor to provide prompt notice to the Borrower of its disclosure
of information under the circumstances described in (i), (ii) and (iii) above
provided the Lender is not prohibited from providing such notice under
applicable Law, and provided further the Lender's failure to provide such notice
shall not constitute a default by the Lender in performance of their obligations
under this Agreement or otherwise result in liability of the Lender to the
Borrower.

         SECTION 10.13 NOTICES. (a) All notices, requests, consents, approvals,
waivers and other communications shall be in writing and mailed, faxed or
delivered, to the address or facsimile number

notices by telephone or facsimile is solely for the convenience and at the
request of the Borrower. The Lender shall be entitled to rely on the authority
of any Person purporting to be a Person authorized by the Borrower to give such

Person on account of any action taken or not taken by the Lender in reliance

any failure by the Lender to receive written confirmation of any telephonic or

         SECTION 10.23 USA PATRIOT ACT NOTIFICATION. The following notification

2001, 31 U.S.C. Section 5318:

                  (a) IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW
ACCOUNT. To help the government fight the funding of terrorism and money
laundering activities, Federal law requires all financial institutions to
obtain, verify, and record information that identifies each person or entity
that opens an account, including any deposit account, treasury management
account, loan, other extension of credit, or other financial services product.
What this means for the Borrower: When the Borrower opens an account, if the
Borrower is an individual, the applicable bank will ask for the Borrower's name,
taxpayer identification number, residential address, date of birth and other
information that will allow such bank to identify the Borrower, and, if the
Borrower is not an individual, such bank will ask for the Borrower's name,
taxpayer identification number, business address, and other information that
will allow such bank to identify the Borrower. The bank may also ask, if

                                       36

the Borrower is an individual, to see the Borrower's driver's license or other
identifying documents, and, if the Borrower is not an individual, to see the
Borrower's legal organizational documents or other identifying documents.

                  (b) GOVERNMENT REGULATION. The Borrower shall not (i) be or
become subject at any time to any law, regulation, or list of any government
agency (including, without limitation, the U.S. Office of Foreign Asset Control
list) that prohibits or limits the Lender from making any advance or extension
of credit to the Borrower or from otherwise conducting business with the
Borrower, or (ii) fail to provide documentary and other evidence of the
Borrower's identity as may be requested by the Lender at any time to enable the
Lender to verify the Borrower's identity or to comply with any applicable law or
regulation, including, without limitation, Section 326 of the USA Patriot Act of
2001, 31 U.S.C. Section 5318.

         IN WITNESS WHEREOF, the parties hereto, intending to be legally bound
hereby, have caused their duly authorized officers to execute and deliver this
Credit Agreement effective as of the day and year first above written.
