Section 8.2 based upon the Borrower's regularly prepared financial statements by
reason of the preceding sentence, then the parties hereto agree to endeavor, in
good faith, to agree upon an amendment to this Agreement that would adjust such
financial covenants in a manner that would not affect the substance thereof, but
would allow compliance therewith to be determined in accordance with the
Borrower's financial statements at that time.

               ------------------------------

                    Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, each Lender severally
agrees to make Revolving Credit Loans to the Borrower at any time or from time
to time on or after the date hereof to the Expiration Date provided that after
giving effect to such Loan the aggregate amount of Loans from such Lender shall
not exceed such Lender's Revolving Credit Commitment minus such Lender's Ratable
Share of the Letters of Credit Outstanding. Within such limits of time and

cancelable at any time for any reason whatsoever, make swing loans (the "Swing
Loans") to the Borrower at any time or from time to time after the date hereof

Credit Loans outstanding hereunder to the Borrower at any time shall never
exceed its Revolving Credit Commitment minus its Ratable Share of the Letters of
Credit Outstanding.  The obligations of each Lender hereunder are several.  The
failure of any Lender to perform its obligations hereunder shall not affect the
Obligations of the Borrower to any other party nor shall any other party be
liable for the failure of such Lender to perform its obligations hereunder.  The
Lenders shall have no obligation to make Revolving Credit Loans hereunder on or
after the Expiration Date.

          2.3  Commitment Fees.

agrees to pay to the Agent for the account of each Lender, as consideration for
such Lender's Revolving Credit Commitment hereunder, a nonrefundable commitment
fee (the "Commitment Fee") equal to the Applicable Commitment Fee Rate (computed
on the basis of a year of 365 or 366  days, as the case may be, and actual days
elapsed) on the average daily difference between the amount of (i) such Lender's
Revolving Credit Commitment as the same may be constituted from time to time
(for purposes of this computation, PNC Bank's Swing Loans shall be deemed to be
borrowed amounts under its Revolving Credit Commitment) and the (ii) the sum of
such Lender's Revolving Credit Loans outstanding plus its Ratable Share of
Letters of Credit Outstanding.  All Commitment Fees shall be payable in arrears
on the first Business Day of each January, April, July, and October after the
date hereof and on the Expiration Date or upon acceleration of the Notes.

          2.4  Revolving Credit Facility Fee.
               ------------------------------

               ----------------------------

                 2.10.1  Issuance of Letters of Credit.
                 --------------------------------------

                    Borrower may request the issuance of a letter of credit
(each a "Letter of Credit") on behalf of itself or another Loan Party by
delivering to the Agent a completed application and agreement for letters of
credit in such form as the Agent may specify from time to time by no later than

reliance on the agreements of the other Lenders set forth in this Section 2.9,
the Agent will issue a Letter of Credit provided that each Letter of Credit
shall (A) have a maximum maturity of twelve (12) months from the date of
issuance, and (B) in no event expire later than five (5) Business Days prior to
the Expiration Date. Any Letter of Credit with a one-year tenor may provide for
the renewal of this Letter of Credit for additional one-year periods as long as
no renewal would extend the expiry date of the Letter of Credit beyond ten (10)
Business Days before the Expiration Date. In no event shall (i) the Letters of
Credit Outstanding exceed, at any one time, $5,000,000 or (ii) the Revolving
Credit Lines outstanding and the Swing Loan exceed, at any one time, the
Revolving Credit Commitments.

                 ------------------------------

                    The Borrower shall pay (i) to the Agent for the ratable

of 360 days and actual days elapsed), which fees shall be computed on the daily
average Letters of Credit Outstanding and shall be payable quarterly in arrears

                 2.10.3  Disbursements, Reimbursement.
                 -------------------------------------

                         2.10.3.1  Immediately upon the Issuance of each Letter
of Credit, each Lender shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Agent a participation in such
Letter of Credit and each drawing thereunder in an amount equal to such Lender's
Ratable Share of the maximum amount available to be drawn under such Letter of
Credit and the amount of such drawing, respectively.

                         2.10.3.2  In the event of any request for a drawing
under a Letter of Credit by the beneficiary or transferee thereof, the Agent
will promptly notify the Borrower. Provided that it shall have received such
notice, the Borrower shall reimburse (such obligation to reimburse the Agent
shall sometimes be referred to as a "Reimbursement Obligation") the Agent prior
to 12:00 noon, Pittsburgh time on each date that an amount is paid by the Agent
under any Letter of Credit (each such date, an "Drawing Date") in an amount
equal to the amount so paid by the Agent. In the event the Borrower fails to
reimburse the Agent for the full amount of any drawing under any Letter of
Credit by 12:00 noon, Pittsburgh time, on the Drawing Date, the Agent will
promptly notify each Lender thereof, and the Borrower shall be deemed to have
requested that Revolving Credit Loans be made by the Lenders under the Base Rate
Option to be disbursed on the Drawing Date under such Letter of Credit, subject
to the amount of the unutilized portion of the Revolving Credit Commitment and
subject to the conditions set forth in Section 7.3 [Each Additional Loan] other
than any notice requirements. Any notice given by the Agent pursuant to this
Section 2.10.3.2 may be oral if immediately confirmed in writing; provided that
the lack of such an immediate confirmation shall not affect the conclusiveness
or binding effect of such notice.

                         2.10.3.3  Each Lender shall upon any notice pursuant to
Section 2.10.3.2 make available to the Agent an amount in immediately available
funds equal to its Ratable Share of the amount of the drawing, whereupon the
participating Lenders shall (subject to Section 2.10.3.4) each be deemed to have
made a Revolving Credit Loan under the Base Rate Option to the Borrower in that
amount. If any Lender so notified fails to make available to the Agent for the
account of the Agent the amount of such Lender's Ratable Share of such amount by
no later than 2:00 p.m., Pittsburgh time on the Drawing Date, then interest
shall accrue on such Lender's obligation to make such payment, from the Drawing
Date to the date on which such Lender makes such payment (i) at a rate per annum
equal to the Federal Funds Effective Rate during the first three days following
the Drawing Date and (ii) at a rate per annum equal to the rate applicable to
Loans under the Revolving Credit Base Rate Option on and after the fourth day
following the Drawing Date. The Agent will promptly give notice of the
occurrence of the Drawing Date, but failure of the Agent to give any such notice
on the Drawing Date or in sufficient time to enable any Lender to effect such
payment on such date shall not relieve such Lender from its obligation under
this Section 2.10.3.3.

                         2.10.3.4  With respect to any unreimbursed drawing that
is not converted into Revolving Credit Loans under the Base Rate Option to the
Borrower in whole or in part as contemplated by Section 2.10.3.2, because of the
Borrower's failure to satisfy the conditions set forth in Section 7.3 [Each
Additional Loan] other than any notice requirements or for any other reason, the
Borrower shall be deemed to have incurred from the Agent a Letter

                                      -24-
<PAGE>

of Credit Borrowing in the amount of such drawing. Such Letter of Credit
Borrowing shall be due and payable on demand (together with interest) and shall
bear interest at the rate per annum applicable to the Revolving Credit Loans
under the Base Rate Option. Each Lender's payment to the Agent pursuant to
Section 2.10.3.3 shall be deemed to be a payment in respect of its participation
in such Letter of Credit Borrowing and shall constitute a Participation Advance
from such Lender in satisfaction of its participation obligation under this
Section 2.10.3.

                 2.10.4  Repayment of Participation Advances.
                 --------------------------------------------

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

                         2.10.4.2  If the Agent is required at any time to
return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or
any official in any Insolvency Proceeding, any portion of the payments made by
any Loan Party to the Agent pursuant to Section 2.10.4.1 in reimbursement of a
payment made under the Letter of Credit or interest or fee thereon, each Lender
shall, on demand of the Agent, forthwith return to the Agent the amount of its
Ratable Share of any amounts so returned by the Agent plus interest thereon from
the date such demand is made to the date such amounts are returned by such
Lender to the Agent, at a rate per annum equal to the Federal Funds Effective
Rate in effect from time to time.

                 2.10.5  Documentation.
                 ----------------------

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

                 2.10.6  Determinations to Honor Drawing Requests.
                 -------------------------------------------------

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

                    In addition to amounts payable as provided in Section 10.5
[Reimbursement of Agent by Borrower, Etc.], the Borrower hereby agrees to
protect, indemnify, pay and save harmless the Agent from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable fees, expenses and disbursements of counsel and allocated
costs of outside counsel) which the Agent may incur or be subject to as a
consequence, direct or indirect, of (i) the issuance of any Letter of Credit,
other than as a result of (A) the gross negligence or willful misconduct of the
Agent as determined by a final judgment of a court of competent jurisdiction or
(B) subject to the following clause (ii), the wrongful dishonor by the Agent of
a proper demand for payment made under any Letter of Credit, or (ii) the failure
of the Agent to honor a drawing under any such Letter of Credit as a result of
any act or omission, whether rightful or wrongful, of any present or future de
jure or de facto government or governmental authority (all such acts or
omissions herein called "Governmental Acts").

                 2.10.9  Liability for Acts and Omissions.
                 -----------------------------------------

                    As between any Loan Party and the Agent, such Loan Party
assumes all risks of the acts and omissions of, or misuse of the Letters of
Credit by, the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, the Agent shall not be
responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or
legal effect of any document submitted by any party in connection with the
application for an issuance of any such Letter of Credit, even if it should in
fact prove to be in any or all respects invalid, insufficient, inaccurate,
fraudulent or forged (even if the Agent shall have been notified thereof); (ii)
the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) the failure of the beneficiary
of any such Letter of Credit, or any other party to which such Letter of Credit
may be transferred, to comply fully with any conditions required in order to
draw upon such Letter of Credit or any other claim of any Loan Party against any
beneficiary of such Letter of Credit, or any such transferee, or any dispute
between or among any Loan Party and any beneficiary of any Letter of Credit or
any such transferee; (iv) errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable,

                                      -27-

telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in
interpretation of technical terms; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under any such
Letter of Credit or of the proceeds thereof; (vii) the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any drawing under
such Letter of Credit; or (viii) any consequences arising from causes beyond the
control of the Agent, including any Governmental Acts, and none of the above
shall affect or impair, or prevent the vesting of, any of the Agent's rights or
powers hereunder. Nothing in the preceding sentence shall relieve the Agent from
liability for the Agent's gross negligence or willful misconduct in connection
with actions or omissions described in such clauses(i) through (viii) of such
sentence.

                    In furtherance and extension and not in limitation of the
specific provisions set forth above, any action taken or omitted by the Agent
under or in connection with the Letters of Credit issued by it or any documents
and certificates delivered thereunder, if taken or omitted in good faith, shall
not put the Agent under any resulting liability to the Borrower or any Lender.

                              4.   INTEREST RATES
                                   --------------

          4.1  Interest Rate Options.
               ---------------------

          The Borrower shall pay interest in respect of the outstanding unpaid
principal amount of the Loan as selected by it from the Base Rate Option or
Euro-Rate Option set forth below applicable to the Loan, it being understood
that, subject to the provisions of this Agreement, the Borrower may select
different Interest Rate Options and different Interest Periods to apply
simultaneously to the Loan comprising different Borrowing Tranches and may
convert to or renew one or more Interest Rate Options with respect to all or any
portion of the Loan comprising any Borrowing Tranche, provided that there shall
                                                      --------
not be at any one time outstanding more than eight (8) Borrowing Tranches in the
aggregate among all of the Loan, and provided further that only the Base Rate
                                     ----------------
Option shall apply to the Swing Loans.  If at any time the designated rate
applicable to any Loan made by any Lender exceeds such Lender's highest lawful
rate, the rate of interest on such Lender's Loan shall be limited to such
Lender's highest lawful rate.

                 4.1.1   Revolving Credit Interest Rate Options.
                 -----------------------------------------------

                    The Borrower shall have the right to select from the
following Interest Rate Options applicable to the Revolving Credit Loans

rate per annum (computed on the basis of a year of 365 or 366 days, as the case
may be, and actual days elapsed) equal to the Base Rate plus the Applicable
Margin, such interest rate to change automatically from time to time effective
as of the effective date of each change in the Base Rate; or

                         (ii) Revolving Credit Euro-Rate Option: A rate per
                              ---------------------------------
annum (computed on the basis of a year of 360 days and actual days elapsed equal
to the Euro-Rate plus the Applicable Margin.

                 4.1.2   Term Loan Interest Rate Options.
                 ----------------------------------------

                    The Borrower shall have the right to select from the

                         (i)  Term Loan Base Rate Option: A fluctuating rate per
                              --------------------------
annum (computed on the basis of a year of 365 or 366 days, as the case may be,
and actual days elapsed) equal to the Base Rate plus the Applicable Margin, such
interest rate to change

                                      -29-
<PAGE>

automatically from time to time effective as of the effective date of each
change in the Base Rate; or

                         (ii) Term Loan Euro-Rate Option: A rate per annum
                              --------------------------
(computed on the basis of a year of 360 days and actual days elapsed equal to
the Euro-Rate plus the Applicable Margin.

                 4.1.3   Rate Quotations.
                 ------------------------

                    The Borrower may call the Agent on or before the date on
which a Loan Request is to be delivered to receive an indication of the rates
then in effect, but it is acknowledged that such projection shall not be binding
on the Agent or the Lenders nor affect the rate of interest which thereafter is
actually in effect when the election is made.

                 4.1.4   Change in Fees or Interest Rates.
                 -----------------------------------------

                    If the Applicable Margin or Applicable Fee Amount is
increased or reduced with respect to any period for which the Borrower has
already paid interest, Letter of Credit Fees or Commitment Fees, the Agent shall
recalculate the additional interest, Letter of Credit Fees or Commitment Fees
due from or to the Borrower and shall, within fifteen (15) Business Days after
the Borrower notifies the Agent of such increase or decrease, give the Borrower
and the Lenders notice of such recalculation.

                         4.1.4.1  Any additional interest, Letter of Credit Fees
or Commitment Fee due from the Borrower shall be paid to the Agent for the
account of the Lenders on the next date on which an interest, Letter of Credit
Fees or fee payment is due; provided, however, that if there are no Loans
                            --------  -------
outstanding or if the Loans are due and payable, such additional interest,
Letter of Credit Fees or Commitment Fee shall be paid promptly after receipt of
written request for payment from the Agent.

                         4.1.4.2  Any interest, Letter of Credit Fees or
Commitment Fee refund due to the Borrower shall be credited against payments
otherwise due from the Borrower on the next interest or fee payment due date or,
if the Loans have been repaid and the Lenders are no longer committed to lend
under this Agreement, the Lenders shall pay the Agent for the account of the
Borrower such interest, Letter of Credit Fees or Commitment Fee refund not later
than five Business Days after written notice from the Agent to the Lenders.

          4.2  Interest Periods.
               ----------------

          At any time when the Borrower shall select, convert to or renew a
Euro-Rate Option, the Borrower shall notify the Agent thereof at least three (3)
Business Days prior to the effective date of such Euro-Rate Option by delivering
a Loan Request.  The notice shall specify an interest period (the " Interest
Period") during which such Interest Rate Option shall apply, such Interest
Period to be one, two, three or six Months; provided, however, that during the
Syndication Period, the Borrower will only select Interest Periods of one Month
each.  Notwithstanding the preceding sentence, the following provisions shall
apply to any selection of, renewal of, or conversion to a Euro-Rate Option:

                                      -30-
<PAGE>

               4.2.1  Ending Date and Business Day.
               ------------------------------------

                   any Interest Period which would otherwise end on a date which
is not a Business Day shall be extended to the next succeeding Business Day
unless such Business Day falls in the next calendar month, in which case such
Interest Period shall end on the next preceding Business Day;

               4.2.2  Amount of Borrowing Tranche.
               -----------------------------------

                   each Borrowing Tranche of Euro-Rate Loans shall be in
integral multiples of $250,000 and not less than $250,000;

               4.2.3  Termination Before Expiration Date.
               ------------------------------------------

                   the Borrower shall not select, convert to or renew an
Interest Period for any portion of the Loans that would end after the Expiration
Date; and

               4.2.4  Renewals.
               ----------------

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

     4.3  Interest After Default.
          ----------------------

     To the extent permitted by Law, upon the occurrence of an Event of
Default and until such time such Event of Default shall have been cured or
waived:

               4.3.1  Interest Rate.
               ---------------------

                   the rate of interest for each Loan otherwise applicable
pursuant to Section 2.10.2 [Letter of Credit Fees] or Section 4.1 [Interest Rate
Options], respectively, shall be increased by 2.0% per annum; and

               4.3.2  Other Obligations.
               -------------------------

                   each other Obligation hereunder if not paid when due shall

applicable under the Revolving Credit Base Rate Option plus an additional 2.0%
per annum from the time such Obligation becomes due and payable and until it is
paid in full.

               4.3.3  Acknowledgment.
               ----------------------

                   The Borrower acknowledges that the increase in rates referred
to in this Section 4.3 reflects, among other things, the fact that such Loans or
other amounts have become a substantially greater risk given their default
status and that the Lenders are entitled to

                                      -31-
<PAGE>

additional compensation for such risk; and all such interest shall be payable by
Borrower upon demand by Agent.

     4.4  Euro-Rate Unascertainable; Illegality; Increased Costs; Deposits Not
          --------------------------------------------------------------------
Available.
---------

               4.4.1  Unascertainable.
               -----------------------

                   If on any date on which a Euro-Rate would otherwise be
determined, the Agent shall have determined that:

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

                         (ii) a contingency has occurred which materially and
adversely affects the London interbank eurodollar market relating to the Euro-
Rate, the Agent shall have the rights specified in Section 4.4.3.

               4.4.2  Illegality; Increased Costs; Deposits Not Available.
               -----------------------------------------------------------

                   If at any time any Lender shall have determined that:

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

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

                         (iii) after making all reasonable efforts, deposits of
the relevant amount in Dollars for the relevant Interest Period for a Loan to
which a Euro-Rate Option applies, respectively, are not available to such Lender
with respect to such Loan, in the London interbank market,

then the Agent shall have the rights specified in Section 4.4.3.

               4.4.3  Agent's and Lender's Rights.
               -----------------------------------

                   In the case of any event specified in Section 4.4.1 above,
the Agent shall promptly so notify the Lenders and the Borrower thereof, and in
the case of an event specified in Section 4.4.2 above, such Lender shall
promptly so notify the Agent and endorse a certificate to such notice as to the
specific circumstances of such notice, and the Agent shall promptly send copies
of such notice and certificate to the other Lenders and the Borrower. Upon such
date as shall be specified in such notice (which shall not be earlier than the
date such notice is given), the obligation of (A) the Lenders, in the case of
such notice given by the Agent, or

                                      -32-
<PAGE>

(B) such Lender, in the case of such notice given by such Lender, to allow the
Borrower to select, convert to or renew a Euro-Rate Option shall be suspended
until the Agent shall have later notified the Borrower, or such Lender shall
have later notified the Agent, of the Agent's or such Lender's, as the case may
be, determination that the circumstances giving rise to such previous
determination no longer exist. If at any time the Agent makes a determination
under Section 4.4.1 and the Borrower has previously notified the Agent of its
selection of, conversion to or renewal of a Euro-Rate Option and such Interest
Rate Option has not yet gone into effect, such notification shall be deemed to
provide for selection of, conversion to or renewal of the Base Rate Option
otherwise available with respect to such Loans. If any Lender notifies the Agent
of a determination under Section 4.4.2, the Borrower shall, subject to the
Borrower's indemnification Obligations under Section 5.6.2 [Indemnity], as to
any Loan of the Lender to which a Euro-Rate Option applies, on the date
specified in such notice either convert such Loan to the Base Rate Option
otherwise available with respect to such Loan or prepay such Loan in accordance
with Section 5.4 [Voluntary Prepayments]. Absent due notice from the Borrower of
conversion or prepayment, such Loan shall automatically be converted to the Base
Rate Option otherwise available with respect to such Loan upon such specified
date.

          4.5  Selection of Interest Rate Options.
               -----------------------------------

          If the Borrower fails to select a new Interest Period to apply to any
Borrowing Tranche of Loans under the Euro-Rate Option at the expiration of an
existing Interest Period applicable to such Borrowing Tranche in accordance with
the provisions of Section 4.1.4 [Interest Periods], the Borrower shall be deemed
to have converted such Borrowing Tranche to the Revolving Credit Base Rate
Option or Term Loan Base Rate Option, as applicable, commencing upon the last
day of the existing Interest Period.

                                 5.   PAYMENTS

not distributed to the Lenders on the same day received by the Agent, the Agent
shall pay the Lenders the Federal Funds Effective Rate with respect to the
amount of such payments for each day held by the Agent and not distributed to
the Lenders. The Agent's and each Lender's statement of account, ledger or
other relevant record shall, in the absence of manifest error, be

                                      -33-
<PAGE>

conclusive as the statement of the amount of principal of and interest on the
Loans and other amounts owing under this Agreement and shall be deemed an

Share, and each selection of, conversion to or renewal of any Interest Rate

5.5 [Mandatory Prepayments] shall be due on the date such mandatory prepayment
is due. Interest on the principal amount of each Loan or other monetary

other monetary Obligation becomes due and payable (whether on the stated
maturity date, upon acceleration or otherwise).

Certain Circumstances]):

          All prepayment notices shall be irrevocable. The principal amount of
the Loans for which a prepayment notice is given, together with interest on such
principal amount except with respect to Loans to which the Base Rate Option
applies, shall be due and payable on the date specified in such prepayment
notice as the date on which the proposed prepayment is to be made. Except as
provided in Section 5.5, all Term Loan prepayments permitted pursuant to this
Section 5.4.1 shall be applied to the unpaid installments of principal of the
Term Loans in the inverse order of scheduled maturities. Except as provided in
Section 4.4.3 [Agent's and Lender's rights], if the Borrower prepays a Loan but
fails to specify the applicable Borrowing Tranche which the Borrower is
prepaying, the prepayment shall be applied (i) first to Revolving Credit Loans
and then to Term Loans; and (ii) after giving effect to the allocations in
clause (i) above and in the preceding sentence, first to Loans to which the Base
Rate Option applies, then to Loans to which the Euro-Rate Option applies. Any
prepayment hereunder shall be subject to the Borrower's Obligation to indemnify
the Lenders under Section 5.6.2 [Indemnity].

               5.4.2  Replacement of a Lender.
               -------------------------------

                   In the event any Lender (i) gives notice under Section 4.4
[Euro-Rate Unascertainable, Etc.] or Section 5.6.1 [Increased Costs, Etc.], (ii)
does not fund Loans because the making of such Loans would contravene any Law
applicable to such Lender, (iii) does not approve any action as to which consent
of the Required Lenders is requested by the Borrower and obtained hereunder, or
(iv) becomes subject to the control of an Official Body (other than normal and
customary supervision), then the Borrower shall have the right at its option,
with the consent of the Agent, which shall not be unreasonably withheld, to
prepay the Loans of such Lender in whole, together with all interest accrued
thereon, and terminate such Lender's Commitment within ninety (90) days after
(w) receipt of such Lender's notice under Section 4.4 [Euro-Rate
Unascertainable, Etc.] or 5.6.1 [Increased Costs, Etc.], (x) the date such

                                      -35-
<PAGE>

Lender has failed to fund Loans because the making of such Loans would
contravene Law applicable to such Lender, (y) the date of obtaining the consent
which such Lender has not approved, or (z) the date such Lender became subject
to the control of an Official Body, as applicable; provided that the Borrower
                                                   --------
shall also pay to such Lender at the time of such prepayment any amounts
required under Section 5.6 [Additional Compensation in Certain Circumstances]
and any accrued interest due on such amount and any related fees; provided,
                                                                  --------
however, that the Commitment and any Term Loan of such Lender shall be provided
by one or more of the remaining Lenders or a replacement Lender acceptable to
the Agent; provided, further, the remaining Lenders shall have no obligation
           --------
hereunder to increase their Commitments.  Notwithstanding the foregoing, the
Agent may only be replaced subject to the requirements of Section 10.14
[Successor Agent] and provided that all Letters of Credit have expired or been
                      --------
terminated or replaced.

               5.4.3  Change of Lending Office.
               --------------------------------

                   Each Lender agrees that upon the occurrence of any event
giving rise to increased costs or other special payments under Section 4.4.2
[Illegality, Etc.] or 5.6.1 [Increased Costs, Etc.] with respect to such Lender,
it will if requested by the Borrower, use reasonable efforts (subject to overall
policy considerations of such Lender) to designate another lending office for
any Loans or Letters of Credit affected by such event, provided that such
                                                       --------
designation is made on such terms that such Lender and its lending office suffer
no economic, legal or regulatory disadvantage, with the object of avoiding the
consequence of the event giving rise to the operation of such Section. Nothing
is this Section 5.4.3 shall affect or postpone any of the Obligations of the
Borrower or any other Loan Party or the rights of the Agent or any Lender
provided in this Agreement.

     5.5  Mandatory Prepayments.
          ---------------------

               5.5.1  Offerings and Dispositions. Within five (5) Business Days
               ---------------------------------
of (i) any equity offering by the Borrower (an "Offering") (whether such equity
is sold in a private placement or a public offering, but not including the
exercise of stock options granted in the ordinary course of business) or (ii)
the sale of a portion of a Loan Party's assets or business (a "Disposition")
(each a "Mandatory Prepayment Date"), the Borrower shall make a mandatory
prepayment of principal on the Term Loan equal to (y) 50% of the net cash
proceeds of the Offering or 100% of the net cash proceeds of the Disposition [to
the extent that Dispositions have involved, in the aggregate, assets with a fair
market value in excess of $1,000,000], as the case may be, together with accrued
interest on such principal amount. Each mandatory prepayment shall be applied
ratably to other remaining unpaid, scheduled principal amortization payments. To
the extent that a mandatory prepayment exceeds the outstanding principal amount
of the Term Loan, such prepayment shall be limited to the amount necessary to
prepay the Term Loan in full.

               5.5.2  Application Among Interest Rate Options.
               -----------------------------------------------

                   All prepayments required pursuant to this Section 5.5 shall
first be applied among the Interest Rate Options to the principal amount of the
Loans subject to the Base

                                      -36-
<PAGE>

Rate Option, then to Loans subject to a Euro-Rate Option. In accordance with
Section 5.6.2 [Indemnity], the Borrower shall indemnify the Lenders for any loss
or expense, including loss of margin, incurred with respect to any such
prepayments applied against Loans subject to a Euro-Rate Option on any day other
than the last day of the applicable Interest Period.

     5.6  Additional Compensation in Certain Circumstances.
          ------------------------------------------------

               5.6.1  Increased Costs or Reduced Return Resulting from Taxes,
               --------------------------------------------------------------
Reserves, Capital Adequacy Requirements, Expenses, Etc.
-------------------------------------------------------

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

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

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

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

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Lender with respect to this Agreement, the Notes or the making, maintenance or
funding of any part of the Loans (or, in the case of any capital adequacy or
similar requirement, to have the effect of reducing the rate of return on any
Lender's capital, taking into consideration such Lender's customary policies
with respect to capital adequacy) by an amount which such Lender in its sole
discretion deems to be material, such Lender shall from time to time notify the
Borrower and the Agent of the amount determined in good faith (using any
averaging and attribution methods employed in good faith) by such Lender to be
necessary to compensate such Lender for such increase in cost, reduction of
income, additional expense or reduced rate of return. Such notice shall set
forth in reasonable detail the basis for such determination. Such amount shall
be due and payable by the Borrower to such Lender ten (10) Business Days after
such notice is given.

               5.6.2  Indemnity.
               -----------------

                   In addition to the compensation required by Section 5.6.1
[Increased Costs, Etc.], the Borrower shall indemnify each Lender against all
liabilities, losses or

                                      -37-
<PAGE>

expenses (including loss of margin, any loss or expense incurred in liquidating
or employing deposits from third parties and any loss or expense incurred in
connection with funds acquired by a Lender to fund or maintain Loans subject to
a Euro-Rate Option), which such Lender sustains or incurs as a consequence of
any

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

                         (ii)  attempt by the Borrower to revoke (expressly, by
later inconsistent notices or otherwise) in whole or part any Loan Requests
under Section 2.5 [Revolving Credit Loan Requests] or Section 4.1.4 [Interest
Periods] or notice relating to prepayments under Section 5.4 [Voluntary
Prepayments], or

                         (iii) default by the Borrower in the performance or
observance of any covenant or condition contained in this Agreement or any other
Loan Document, including any failure of the Borrower to pay when due (by
acceleration or otherwise) any principal interest Committed Fee or any other
amount due hereunder.

                    If any Lender sustains or incurs any such loss or expense,
it shall from time to time notify the Borrower of the amount determined in good
faith by such Lender (which determination may include such assumptions,
allocations of costs and expenses and averaging or attribution methods as such
Lender shall deem reasonable) to be necessary to indemnify such Lender for such
loss or expense. Such notice shall set forth in reasonable detail the basis for
such determination. Such amount shall be due and payable by the Borrower to such
Lender ten (10) Business Days after such notice is given.

     5.7  Settlement Date Procedures.
          --------------------------

     In order to minimize the transfer of funds between the Lenders and the
Agent, the Borrower may borrow, repay and reborrow Swing Loans and PNC may make
Swing Loans as provided in Section 2.1.2 hereof during the period between
Settlement Dates. Not later than _________ on each Settlement Date, the Agent
shall notify each Lender of its Ratable Share of the total of the Revolving
Credit Loans and the Swing Loans (each a "Required Share"). Prior to _________,
Pittsburgh time, on such Settlement Date, each Lender shall pay to the Agent the
amount equal to the difference between its Required Share and its Revolving
Credit Loans, and the Agent shall pay to each Lender its Ratable Share of all
payments made by the Borrower to the Agent with respect to the Revolving Credit
Loans. The Agent shall also effect settlement in accordance with the foregoing
sentence on the proposed Borrowing Dates for Revolving Credit Loans and on
Mandatory Prepayment Dates and may at its option effect settlement on any other
Business Day. These settlement procedures are established solely as a matter of
administrative convenience, and nothing contained in this Section 5.7 shall
relieve the Lenders of their obligations to fund Revolving Credit Loans on dates
other than a Settlement Date pursuant to Section 2.1.2. The Agent may at any
time at its option for any reason whatsoever require each Lender to pay
immediately to the Agent such Lender's Ratable Share of the outstanding

                                      -38-
<PAGE>

Revolving Credit Loans and each Lender may at any time require the Agent to pay
immediately to such Lender its Ratable Share of all payments made by the
borrower to the Agent with respect to the Revolving Credit Loans.

necessity for any consent which has not previously been obtained upon
consummation of the transactions contemplated hereby. To the extent that the
leases of property of the Foreign Subsidiaries of each Loan Party are not in

Material Adverse Change.

               6.1.9  Financial Statements.
               ----------------------------

                      (i)  Historical Statements. The Borrower has delivered to
                           ---------------------
the Agent copies of its audited consolidated year-end financial statements for
and as of the end of the 1999 fiscal year ended June 30, 1999 (the "Annual
Statements"). In addition, the Borrower has delivered to the Agent copies of its
unaudited consolidated interim financial statements for the fiscal year to date
and as of the end of the fiscal quarter ended March 31, 2000 (the "Interim
Statements") (the Annual and Interim Statements being collectively referred to
as the "Historical Statements"). The Historical Statements were compiled from
the books and records maintained by the Borrower's management, are correct and
complete and fairly represent the consolidated financial condition of the
Borrower and its Subsidiaries as of their dates and the results of operations
for the fiscal periods then ended and have been prepared in accordance with GAAP
consistently applied, subject (in the case of the Interim Statements) to normal
year-end audit adjustments.

                      (ii) Financial Projections. The Borrower has delivered to
                           ---------------------
the Agent financial projections of the Borrower and its Subsidiaries for the
period from July 1, 1999 through June 30, 2005 derived from various assumptions
of the Borrower's management (the "Financial Projections"). The Financial
Projections represent a reasonable range of

                                      -41-
<PAGE>

possible results in light of the history of the business, present and
foreseeable conditions and the intentions of the Borrower's management. The
Financial Projections accurately reflect the liabilities of the Borrower and its
Subsidiaries upon consummation of the transactions contemplated hereby as of the
Closing Date.

                       (iii)  Accuracy of Financial Statements. Neither the
                              --------------------------------
Borrower nor any Subsidiary of the Borrower has any liabilities, contingent or
otherwise, or forward or long-term commitments that are not disclosed in the
Historical Statements or in the notes thereto, and except as disclosed therein
there are no unrealized or anticipated losses from any commitments of the
Borrower or any Subsidiary of the Borrower which may cause a Material Adverse
Change. Since June 30, 1999, no Material Adverse Change has occurred.

               6.1.10  Use of Proceeds; Margin Stock; Section 20 Subsidiaries.
               --------------------------------------------------------------

                       6.1.10.1  Permitted Uses.
                                 --------------

                    Up to $35,000,000 in aggregate of the Revolving Credit
Facility may be used on or after the Closing Date and until and including the
Acquisition Date (i) to fund the cash portion of and the fees and expenses
associated with the Acquisition of LPC, (ii) to refinance existing indebtedness
of the Borrower and, after the Tender Date, of LPC, (iii) to pay fees and
expenses associated with the Credit Facilities, and (iv) for working capital
purposes of the Loan Parties. After the Acquisition Date, the Revolving Credit
Facility may be used for working capital purposes of the Loan Parties.

                       6.1.10.2  Margin Stock.
                                 ------------

                    None of the Loan Parties or any Subsidiaries of any Loan
Party engages or intends to engage principally, or as one of its important
activities, in the business of extending credit for the purpose, immediately,
incidentally or ultimately, of purchasing or carrying margin stock in violation
of Regulation U. The Borrower does not intend to request Loans in an aggregate
amount more than the sum of (i) 50% of the fair market value of the margin stock
of the Loan Parties plus (ii) 100% of the good faith loan value (as defined in
Regulation U) of all other Collateral. No part of the proceeds of any Loan has
been or will be used, immediately, incidentally or ultimately, to purchase or
carry any margin stock to an extent that would violate Regulation U or to extend
credit to others for the purpose of purchasing or carrying any margin stock or
to refund Indebtedness originally incurred for such purpose, or for any purpose
which entails a violation of or which is inconsistent with the provisions of the
regulations of the Board of Governors of the Federal Reserve System. None of the
Loan Parties or any Subsidiary of any Loan Party holds or intends to hold margin
stock in such amounts that more than 50% of the reasonable value of the assets
of any Loan Party or Subsidiary of any Loan Party are or will be represented by
margin stock.

                       6.1.10.3  Section 20 Subsidiaries.
                                 -----------------------

                    The Loan Parties do not intend to use and shall not use any
portion of the proceeds of the Loans, directly or indirectly (i) knowingly to
purchase any Ineligible Securities from a Section 20 Subsidiary during any
period in which such Section 20

                                      -42-
<PAGE>

Subsidiary makes a market in such Ineligible Securities, (ii) knowingly to
purchase during the underwriting or placement period Ineligible Securities being
underwritten or privately placed by a Section 20 Subsidiary, or (iii) to make
payments of principal or interest on Ineligible Securities underwritten or
privately placed by as Section 20 Subsidiary and issued by or for the benefit of
any Loan Party or any Affiliate of any Loan Party.

                    6.1.11  Full Disclosure.
                    ------------------------

                         Neither this Agreement nor any other Loan Document, nor
any certificate, statement, agreement or other documents furnished to the Agent
or any Lender in connection herewith or therewith, contains any untrue statement

                                   ---------

          10.1   Appointment.
                 -----------

          Each Lender hereby irrevocably designates, appoints and authorizes PNC
Bank to act as Agent for such Lender under this Agreement and to execute and
deliver or accept on behalf of each of the Lenders the other Loan Documents.
Each Lender hereby irrevocably authorizes, and each holder of any Note by the
acceptance of a Note shall be deemed irrevocably to authorize the Agent to take
such action on its behalf under the provisions of this Agreement and the other
Loan Documents and any other instruments and agreements referred to herein, and
to exercise such powers and to perform such duties hereunder as are specifically
delegated to or required of the Agent by the terms hereof, together with such
powers as are reasonably incidental thereto.  PNC Bank agrees to act as the
Agent on behalf of the Lenders to the extent provided in this Agreement.


          10.2   Delegation of Duties.
                 --------------------

          The Agent may perform any of its duties hereunder by or through agents
or employees (provided such delegation does not constitute a relinquishment of
              --------
its duties as Agent) and, subject to Sections 10.5 [Reimbursement of Agent by
Borrower, Etc.] and 10.6, shall be entitled to engage and pay for the advice or
services of any attorneys, accountants or other experts concerning all matters
pertaining to its duties hereunder and to rely upon any advice so obtained.


          10.3   Nature of Duties; Independent Credit Investigation.
                 --------------------------------------------------

          The Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and no implied covenants, functions,
responsibilities, duties, obligations, or liabilities shall be read into this
Agreement or otherwise exist.  The duties of the Agent shall be mechanical and
administrative in nature; the Agent shall not have by reason of this Agreement a
fiduciary or trust relationship in respect of any Lender; and nothing in this
Agreement, expressed or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in respect of this Agreement except as
expressly set forth herein.  Without limiting the generality of

                                      -75-
<PAGE>

the foregoing, the use of the term "agent" in this Agreement with reference to
the Agent is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable Law. Instead, such
term is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship between independent contracting
parties. Each Lender expressly acknowledges (i) that the Agent has not made any
representations or warranties to it and that no act by the Agent hereafter
taken, including any review of the affairs of any of the Loan Parties, shall be
deemed to constitute any representation or warranty by the Agent to any Lender;
(ii) that it has made and will continue to make, without reliance upon the
Agent, its own independent investigation of the financial condition and affairs
and its own appraisal of the creditworthiness of each of the Loan Parties in
connection with this Agreement and the making and continuance of the Loans
hereunder; and (iii) except as expressly provided herein, that the Agent shall
have no duty or responsibility, either initially or on a continuing basis, to
provide any Lender with any credit or other information with respect thereto,
whether coming into its possession before the making of any Loan or at any time
or times thereafter.


          10.4   Actions in Discretion of Agent; Instructions From the Lenders.
                 -------------------------------------------------------------

          The Agent agrees, upon the written request of the Required Lenders, to
take or refrain from taking any action of the type specified as being within the
Agent's rights, powers or discretion herein, provided that the Agent shall not
                                             --------
be required to take any action which exposes the Agent to personal liability or
which is contrary to this Agreement or any other Loan Document or applicable
Law.  In the absence of a request by the Required Lenders, the Agent shall have
authority, in its sole discretion, to take or not to take any such action,
unless this Agreement specifically requires the consent of the Required Lenders
or all of the Lenders.  Any action taken or failure to act pursuant to such
instructions or discretion shall be binding on the Lenders, subject to Section
10.6 [Exculpatory Provisions, Etc.].  Subject to the provisions of Section 10.6,
no Lender shall have any right of action whatsoever against the Agent as a
result of the Agent acting or refraining from acting hereunder in accordance
with the instructions of the Required Lenders, or in the absence of such
instructions, in the absolute discretion of the Agent.

          10.5   Reimbursement and Indemnification of Agent by the Borrower.
                 ----------------------------------------------------------

          The Borrower unconditionally agrees to pay or reimburse the Agent and

(b) all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by the Agent
hereunder or thereunder, provided that the Borrower shall not be liable for any
                         --------
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements if the same results from the
Agent's gross negligence or willful misconduct, or if the Borrower was not given
notice of the subject claim and the opportunity to participate in the defense
thereof, at its expense (except that the Borrower shall remain liable to the
extent such failure to give notice does not result in a loss to the Borrower),
or if the same results from a compromise or settlement agreement entered into
without the consent of the Borrower, which shall not be unreasonably withheld.
In addition, the Borrower agrees to reimburse and pay all reasonable out-of-
pocket expenses of the Agent's regular employees and agents engaged periodically
to perform audits of the Loan Parties' books, records and business properties.

          10.6   Exculpatory Provisions; Limitation of Liability.
                 -----------------------------------------------

          Neither the Agent nor any of its directors, officers, employees,
agents, attorneys or Affiliates shall (a) be liable to any Lender for any action
taken or omitted to be taken by it or them hereunder, or in connection herewith
including pursuant to any Loan Document, unless caused by its or their own gross
negligence or willful misconduct, (b) be responsible in any manner to any of the
Lenders for the effectiveness, enforceability, genuineness, validity or the due
execution of this Agreement or any other Loan Documents or for any recital,
representation, warranty, document, certificate, report or statement herein or
made or furnished under or in connection with this Agreement or any other Loan
Documents, or (c) be under any obligation to any of the Lenders to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions hereof or thereof on the part of the Loan Parties, or the financial
condition of the Loan Parties, or the existence or possible existence of any
Event of Default or Potential Default. No claim may be made by any of the Loan
Parties, any Lender, the Agent or any of their respective Subsidiaries against
the Agent, any Lender or any of their respective directors, officers, employees,
agents, attorneys or Affiliates, or any of them, for any special, indirect or
consequential damages or, to the fullest extent permitted by Law, for any
punitive damages in respect of any claim or cause of action (whether based on
contract, tort, statutory liability, or any other ground) based on, arising out
of or related to any Loan Document or the transactions contemplated hereby or
any act, omission or event occurring in connection therewith, including the
negotiation, documentation, administration or collection of the Loans, and each
of the Loan Parties, (for itself and on behalf of each of its Subsidiaries), the
Agent and each Lender hereby waive, releases and agree never to sue upon any
claim for any such damages, whether such claim now exists or hereafter arises
and whether or not it is now known or suspected to exist in its favor. Each
Lender agrees that, except for notices, reports and other documents expressly
required to be furnished to the Lenders by the Agent hereunder or given to the
Agent for the account of or with copies for the Lenders, the Agent and each of
its directors, officers, employees, agents, attorneys or Affiliates shall not
have any duty or responsibility to provide any Lender with any credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of the Loan Parties

                                      -77-
<PAGE>

which may come into the possession of the Agent or any of its directors,
officers, employees, agents, attorneys or Affiliates.

          10.7   Reimbursement and Indemnification of Agent by Lenders.
                 -----------------------------------------------------

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

          10.8   Reliance by Agent.
                 -----------------

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

          10.9   Notice of Default.
                 -----------------

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

          10.10  Notices.
                 -------

          The Agent shall promptly send to each Lender a copy of all notices
received from the Borrower pursuant to the provisions of this Agreement or the
other Loan Documents

                                      -78-
<PAGE>

promptly upon receipt thereof. The Agent shall promptly notify the Borrower and
the other Lenders of each change in the Base Rate and the effective date
thereof.

          10.11  Lenders in Their Individual Capacities.
                 --------------------------------------

          With respect to its Revolving Credit Commitment, the Revolving Credit
Loans, the Term Loan Commitment and the Term Loan made by it and any other
rights and powers given to it as a Lender hereunder or under any of the other
Loan Documents, the Agent shall have the same rights and powers hereunder as any
other Lender and may exercise the same as though it were not the Agent, and the
term "Lenders" shall, unless the context otherwise indicates, include the Agent
in its individual capacity. PNC and its Affiliates and each of the Lenders and
their respective Affiliates may, without liability to account, except as
prohibited herein, make loans to, accept deposits from, discount drafts for, act
as trustee under indentures of, and generally engage in any kind of banking or
trust business with, the Loan Parties and their Affiliates, in the case of the
Agent, as though it were not acting as Agent hereunder and in the case of each
Lender, as though such Lender were not a Lender hereunder. The Lenders
acknowledge that, pursuant to such activities, the Agent or its Affiliates may
(i) receive information regarding the Loan Parties (including information that
may be subject to confidentiality obligations in favor of the Loan Parties) and
acknowledge that the Agent shall be under no obligation to provide such
information to them, and (ii) accept fees and other consideration from the Loan
Parties for services in connection with this Agreement and otherwise without
having to account for the same to the Lenders.

          10.12  Holders of Notes.
                 ----------------

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

          10.13  Equalization of Lenders.
                 -----------------------

          The Lenders and the holders of any participations in any Commitments
or Loans or other rights or obligations of a Lender hereunder agree among
themselves that, with respect to all amounts received by any Lender or any such
holder for application on any Obligation hereunder or under any Note or under
any such participation, whether received by voluntary payment, by realization
upon security, by the exercise of the right of set-off or banker's lien, by
counterclaim or by any other non-pro rata source, equitable adjustment will be
made in the manner stated in the following sentence so that, in effect, all such
excess amounts will be shared ratably among the Lenders and such holders in
proportion to their interests in payments, under the Notes, except as otherwise
provided in Section 4.4.3 [Agent's and Lender's Rights], 5.4.2 [Replacement of a
Lender] or 5.6 [Additional Compensation in Certain Circumstances].  The Lenders
or any such holder receiving any such amount shall purchase for cash from each
of the other Lenders an interest in such Lender's Loans in such amount as shall
result in a ratable

                                      -79-
<PAGE>

participation by the Lenders and each such holder in the aggregate unpaid amount
under the Notes, provided that if all or any portion of such excess amount is
                 --------
thereafter recovered from the Lender or the holder making such purchase, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, together with interest or other amounts, if any, required by law
(including court order) to be paid by the Lender or the holder making such
purchase.

          10.14  Successor Agent.
                 ---------------

          The Agent (i) may resign as Agent or (ii) shall resign if such
resignation is requested by the Required Lenders (if the Agent is a Lender, the
Agent's Loans and its Commitment shall be considered in determining whether the
Required Lenders have requested such resignation) or required by Section 5.4.2
[Replacement of a Lender], in either case of (i) or (ii) by giving not less than
thirty (30) days' prior written notice to the Borrower. If the Agent shall
resign under this Agreement, then either (a) the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, subject to the consent
of the Borrower, such consent not to be unreasonably withheld, or (b) if a
successor agent shall not be so appointed and approved within the thirty (30)
day period following the Agent's notice to the Lenders of its resignation, then
the Agent shall appoint, with the consent of the Borrower, such consent not to
be unreasonably withheld, a successor agent who shall serve as Agent until such
time as the Required Lenders appoint and the Borrower consents to the
appointment of a successor agent. Upon its appointment pursuant to either clause
(a) or (b) above, such successor agent shall succeed to the rights, powers and
duties of the Agent, and the term "Agent" shall mean such successor agent,
effective upon its appointment, and the former Agent's rights, powers and duties
as Agent shall be terminated without any other or further act or deed on the
part of such former Agent or any of the parties to this Agreement. After the
resignation of any Agent hereunder, the provisions of this Section 10 shall
inure to the benefit of such former Agent and such former Agent shall not by
reason of such resignation be deemed to be released from liability for any
actions taken or not taken by it while it was an Agent under this Agreement.

          10.15  Agent's Fee.
                 -----------

          The Borrower shall pay to the Agent a nonrefundable fee (the "Agent's
Fee") under the terms of a letter (the "Agent's Letter") between the Borrower
and Agent, as amended from time to time.

          10.16  Availability of Funds.
                 ---------------------

          The Agent may assume that each Lender has made or will make the
proceeds of a Loan available to the Agent unless the Agent shall have been
notified by such Lender on or before the later of (1) the close of Business on
the Business Day preceding the Borrowing Date with respect to such Loan or two
(2) hours before the time on which the Agent actually funds the proceeds of such
Loan to the Borrower (whether using its own funds pursuant to this Section 10.16
or using proceeds deposited with the Agent by the Lenders and whether such
funding occurs before or after the time on which Lenders are required to deposit
the proceeds of such Loan with the Agent). The Agent may, in reliance upon such
assumption (but shall not be

                                      -80-
<PAGE>

required to), make available to the Borrower a corresponding amount. If such
corresponding amount is not in fact made available to the Agent by such Lender,
the Agent shall be entitled to recover such amount on demand from such Lender
(or, if such Lender fails to pay such amount forthwith upon such demand from the
Borrower) together with interest thereon, in respect of each day during the
period commencing on the date such amount was made available to the Borrower and
ending on the date the Agent recovers such amount, at a rate per annum equal to
(i) the Federal Funds Effective Rate during the first three (3) days after such
interest shall begin to accrue and (ii) the applicable interest rate in respect
of such Loan after the end of such three-day period.

          10.17  Calculations.
                 ------------

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

          10.18  Beneficiaries.
                 -------------

          Except as expressly provided herein, the provisions of this Section 10
are solely for the benefit of the Agent and the Lenders, and the Loan Parties
shall not have any rights to rely on or enforce any of the provisions hereof.
In performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Lenders and does not assume and shall not be deemed to
have assumed any obligation toward or relationship of agency or trust with or
for any of the Loan Parties.

                              11.  MISCELLANEOUS
                                   -------------

          11.1   Modifications, Amendments or Waivers.
                 ------------------------------------

          With the written consent of the Required Lenders, the Agent, acting on
behalf of all the Lenders, and the Borrower, on behalf of the Loan Parties, may
from time to time enter into written agreements amending or changing any
provision of this Agreement or any other Loan Document or the rights of the
Lenders or the Loan Parties hereunder or thereunder, or may grant written
waivers or consents to a departure from the due performance of the Obligations
of the Loan Parties hereunder or thereunder.  Any such agreement, waiver or
consent made with such written consent shall be effective to bind all the
Lenders and the Loan Parties; provided, that, without the written consent of all
                              --------
the Lenders, no such agreement, waiver or consent may be made which will:

                                      -81-
<PAGE>

               11.1.1   Increase of Commitment; Extension or Expiration Date.

Term Loan Commitment of any Lender hereunder or extend the Expiration Date;

               11.1.2   Extension of Payment; Reduction of Principal Interest or
               -----------------------------------------------------------------
Fees; Modification of Terms of Payment.
--------------------------------------

                    Whether or not any Loans are outstanding, extend the time
for payment of principal or interest of any Loan (excluding the due date of any
mandatory prepayment of a Loan or any mandatory Commitment reduction in
connection with such a mandatory prepayment hereunder except for mandatory
reductions of the Commitments on the Expiration Date), the Commitment Fee or any
other fee payable to any Lender, or reduce the principal amount of or the rate
of interest borne by any Loan or reduce the Commitment Fee or any other fee
payable to any Lender, or otherwise affect the terms of payment of the
principal of or interest of any Loan, the Commitment Fee or any other fee
payable to any Lender;

               11.1.3   Release of Collateral or Guarantor.
               -------------------------------------------

                    Except for sales of assets permitted by Section 8.2.7
[Disposition of Assets or Subsidiaries], release any Collateral consisting of
capital stock or other ownership interests of any Loan Party or its Subsidiary
or substantially all of the assets of any Loan Party, any Guarantor from its
Obligations under the Guaranty Agreement or any other security for any of the
Loan Parties' Obligations; or

               11.1.4   Miscellaneous
               ----------------------

                    Amend Section 5.2 [Pro Rata Treatment of Lenders], 10.6
[Exculpatory Provisions, Etc.] or 10.13 [Equalization of Lenders] or this
Section 11.1, alter any provision regarding the pro rata treatment of the
Lenders, change the definition of Required Lenders, or change any requirement
providing for the Lenders or the Required Lenders to authorize the taking of any
action hereunder;

provided, further, that no agreement, waiver or consent which would modify the
--------
interests, rights or obligations of the Agent in its capacity as Agent or as the
issuer of Letters of Credit shall be effective without the written consent of
the Agent.

          11.2   No Implied Waivers; Cumulative Remedies; Writing Required.
                 ---------------------------------------------------------

          No course of dealing and no delay or failure of the Agent or any
Lender in exercising any right, power, remedy or privilege under this Agreement
or any other Loan Document shall affect any other or future exercise thereof or
operate as a waiver thereof, nor shall any single or partial exercise thereof or
any abandonment or discontinuance of steps to enforce such a right, power,
remedy or privilege preclude any further exercise thereof or of any other right,
power, remedy or privilege. The rights and remedies of the Agent and the Lenders
under this Agreement and any other Loan Documents are cumulative and not
exclusive of any rights or remedies which they would otherwise have. Any waiver,
permit, consent or approval of

                                      -82-
<PAGE>

any kind or character on the part of any Lender of any breach or default under
this Agreement or any such waiver of any provision or condition of this
Agreement must be in writing and shall be effective only to the extent
specifically set forth in such writing.

          11.3 Reimbursement and Indemnification of Lenders by the Borrower;
               -------------------------------------------------------------
               Taxes.
               -----

          The Borrower agrees unconditionally upon demand to pay or reimburse to
each Lender (other than the Agent, as to which the Borrower's Obligations are
set forth in Section 10.5 [Reimbursement of Agent By Borrower, Etc.]) and to
save such Lender harmless against (i) liability for the payment of all
reasonable out-of-pocket costs, expenses and disbursements (including fees and
expenses of counsel for each Lender except with respect to (a) and (b) below),
incurred by such Lender (a) in connection with the administration and
interpretation of this Agreement, and other instruments and documents to be
delivered hereunder, (b) relating to any amendments, waivers or consents
pursuant to the provisions hereof, (c) in connection with the enforcement of
this Agreement or any other Loan Document, or collection of amounts due
hereunder or thereunder or the proof and allowability of any claim arising under
this Agreement or any other Loan Document, whether in bankruptcy or receivership
proceedings or otherwise, and (d) in any workout or restructuring or in
connection with the protection, preservation, exercise or enforcement of any of
the terms hereof or of any rights hereunder or under any other Loan Document or
in connection with any foreclosure, collection or bankruptcy proceedings, or
(ii) all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against such Lender,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by such Lender
hereunder or thereunder, provided that the Borrower shall not be liable for any
                         --------
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements (A) if the same results from
such Lender's gross negligence or willful misconduct, or (B) if the Borrower was
not given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense (except that the Borrower shall remain liable to
the extent such failure to give notice does not result in a loss to the
Borrower), or (C) if the same results from a compromise or settlement agreement
entered into without the consent of the Borrower, which shall not be
unreasonably withheld.  The Lenders will attempt to minimize the fees and
expenses of legal counsel for the Lenders which are subject to reimbursement by
the Borrower hereunder by considering the usage of one law firm to represent the
Lenders and the Agent if appropriate under the circumstances.  The Borrower
agrees unconditionally to pay all stamp, document, transfer, recording or filing
taxes or fees and similar impositions now or hereafter determined by the Agent
or any Lender to be payable in connection with this Agreement or any other Loan
Document, and the Borrower agrees unconditionally to save the Agent and the
Lenders harmless from and against any and all present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees or impositions.

          11.4 Holidays.
               --------

          Whenever payment of a Loan to be made or taken hereunder shall be due
on a day which is not a Business Day such payment shall be due on the next
Business Day and such

                                      -83-
<PAGE>

extension of time shall be included in computing interest and fees, except that
the Loans shall be due on the Business Day preceding the Expiration Date if the
Expiration Date is not a Business Day. Whenever any payment or action to be made
or taken hereunder (other than payment of the Loans) shall be stated to be due
on a day which is not a Business Day, such payment or action shall be made or
taken on the next following Business Day (except as provided in Section 4.1.4
[Interest Periods] with respect to Interest Periods under the Euro-Rate Option),
and such extension of time shall not be included in computing interest or fees,
if any, in connection with such payment or action.

          11.5 Funding by Branch, Subsidiary or Affiliate.
               ------------------------------------------

                    11.5.1  Notional Funding.
                    ------------------------

                         Each Lender shall have the right from time to time,
without notice to the Borrower, to deem any branch, Subsidiary or Affiliate
(which for the purposes of this Section 11.5 shall mean any corporation or
association which is directly or indirectly controlled by or is under direct or
indirect common control with any corporation or association which directly or
indirectly controls such Lender) of such Lender to have made, maintained or
funded any Loan to which the Euro-Rate Option applies at any time, provided that
                                                                   --------
immediately following (on the assumption that a payment were then due from the
Borrower to such other office), and as a result of such change, the Borrower
would not be under any greater financial obligation pursuant to Section 5.6
[Additional Compensation in Certain Circumstances] than it would have been in
the absence of such change. Notional funding offices may be selected by each
Lender without regard to such Lender's actual methods of making, maintaining or
funding the Loans or any sources of funding actually used by or available to
such Lender.

                    11.5.2  Actual Funding.
                    ----------------------

                         Each Lender shall have the right from time to time to
make or maintain any Loan by arranging for a branch, Subsidiary or Affiliate of
such Lender to make or maintain such Loan subject to the last sentence of this
Section 11.5.2. If any Lender causes a branch, Subsidiary or Affiliate to make
or maintain any part of the Loans hereunder, all terms and conditions of this
Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the Loans to the same extent as if such Loans were
made or maintained by such Lender, but in no event shall any Lender's use of
such a branch, Subsidiary or Affiliate to make or maintain any part of the Loans
hereunder cause such Lender or such branch, Subsidiary or Affiliate to incur any
cost or expenses payable by the Borrower hereunder or require the Borrower to
pay any other compensation to any Lender (including any expenses incurred or

respective successors and assigns, except that none of the Loan Parties may
assign or transfer any of its rights and Obligations hereunder or any interest
herein. Each Lender may, at its own cost, make assignments of or sell

participant relating thereto and not to include any voting rights except with
respect to changes of the type referenced in Sections 11.1.1 [Increase of
Commitment, Etc.], 11.1.2 [Extension of Payment, Etc.], or 11.1.3 [Release of
Collateral or Guarantor], all of such Lender's obligations under this Agreement
or any other Loan Document shall remain unchanged, and all amounts payable by
any Loan Party hereunder or thereunder shall be determined as if such Lender had
not sold such participation.

Documents to any Federal Reserve Lender in accordance with Regulation A of the
FRB or U.S. Treasury Regulation 31 CFR Section 203.14 without notice to or

Commitments.
