hereof applied on a basis consistent with those used in preparing the Annual

event of any change after the date hereof in GAAP, and if such change would
result in the inability to determine compliance with the financial covenants set

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

the Borrower shall object to determining such compliance on such basis at the
time of delivery of such financial statements due to any change in GAAP or the
rules promulgated with respect thereto or (b) either the Agent or the Required
Banks shall so object in writing within 60 days after delivery of such financial
statements (or after the Banks have been informed of the changes in GAAP
affecting such financial statements, if later), then for the period following
such objection, unless otherwise agreed by the Borrower and the Required Banks,
such calculations shall be made on a basis consistent with the most recent
financial statements delivered by the Borrower to the Banks as to which no such
objection shall have been made.

     2. REVOLVING CREDIT AND SWING LOAN FACILITIES

     2.1 REVOLVING CREDIT COMMITMENTS.

           2.1.1. REVOLVING CREDIT LOANS.

                  Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, each Bank severally agrees
to make Revolving Credit Loans in either Dollars or one or more Optional
Currencies to the Borrower at any time or from time to time on or after the date
hereof to the Expiration Date provided that (i) after giving effect to each such
Loan the aggregate Dollar Equivalent amount of Loans from such Bank shall not
exceed such Bank's Revolving Credit Commitment minus such Bank's Ratable Share
of the Dollar Equivalent amount of Letters of Credit Outstanding and further
minus such Bank's Ratable Share of outstanding Swing Loans, and (ii) no Loan to
which the Base Rate Option applies shall be made in an Optional Currency, and
PROVIDED, FURTHER that the Dollar Equivalent Revolving Facility Usage at any
time shall not exceed the Revolving Credit Commitments of all the Banks. Within
such limits of time and amount and subject to the other provisions of this
Agreement, the Borrower may borrow, repay and reborrow pursuant to this Section
2.1.

     2.2 SWING LOAN COMMITMENT.

           2.2.1. SWING LOANS.

                  Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, and in order to facilitate
loans and repayments between Settlement Dates, PNC Bank may, at its option,
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
to, but not including, the Expiration Date, in an aggregate principal amount up
to but not in excess of $10,000,000 (the "Swing Loan Commitment"), PROVIDED that
the Dollar Equivalent Revolving Facility Usage at any time, shall not exceed the
Revolving Credit Commitments of all the Banks. Within such limits of time and
amount and subject to the other provisions of this Agreement, the Borrower may
borrow, repay and reborrow pursuant to this Section 2.2.1.

     2.3 NATURE OF BANKS' OBLIGATIONS WITH RESPECT TO REVOLVING CREDIT LOANS.

     Each Bank shall be obligated to participate in each request for Revolving
Credit Loans pursuant to Section 2.5 [Revolving Credit Loan Requests] in
accordance with its Ratable Share. The aggregate Dollar Equivalent amount of
each Bank's Revolving Credit Loans outstanding hereunder to the Borrower at any
time shall never exceed its Revolving Credit Commitment minus its Ratable Share
of the Dollar Equivalent amount of Letters of Credit Outstanding, subject to
Section 5.4.6 [Mandatory Prepayment-Currency Fluctuations]. The obligations of
each Bank hereunder are several. The failure of any Bank 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 Bank to
perform its obligations hereunder. The


                                       29
<Page>

Banks shall have no obligation to make Revolving Credit Loans hereunder on or
after the Expiration Date.

     2.4 COMMITMENT FEES.

     Accruing from the date hereof until the Expiration Date, the Borrower
agrees to pay to the Agent in Dollars for the account of each Bank, as
consideration for such Bank'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 360 days, as the case
may be, and actual days elapsed) on the average daily difference between the
amount of (i) such Bank'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 Bank'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 day of each July,
October, January and April after the date hereof and on the Expiration Date or
upon acceleration of the Loans.

     2.5 REVOLVING CREDIT LOAN REQUESTS; SWING LOAN REQUESTS.

           2.5.1. REVOLVING CREDIT LOAN REQUESTS.

                  Except as otherwise provided herein, the Borrower may from
time to time prior to the Expiration Date request the Banks to make Revolving
Credit Loans, or renew or convert the Interest Rate Option applicable to
existing Revolving Credit Loans pursuant to Section 4.2 [Interest Periods], by
delivering to the Agent, not later than 11:00 a.m., Pittsburgh time, (i) three
(3) Business Days prior to the proposed Borrowing Date with respect to the
making of Revolving Credit Loans in Dollars to which the Euro-Rate Option
applies or the date of conversion to or the renewal of the Euro-Rate Option for
any such Loans and four (4) Business Days prior to the proposed Borrowing Date
with respect to the making of Revolving Credit Loans in an Optional Currency or
the date of conversion to or renewal of the Euro-Rate Option for Revolving
Credit Loans in an Optional Currency; and (ii) one (1) Business Day prior to
either the proposed Borrowing Date with respect to the making of a Revolving
Credit Loan to which the Base Rate Option applies or the last day of the
preceding Interest Period with respect to the conversion to the Base Rate Option
for any Loan, of a duly completed Loan Request therefor substantially in the
form of EXHIBIT 2.5.1. Each Loan Request shall be irrevocable and shall specify
(i) the proposed Borrowing Date; (ii) the aggregate amount of the proposed Loans
(expressed in the currency in which such Loans shall be funded if such Loans
shall be funded in an Optional Currency) comprising each Borrowing Tranche, the
Dollar Equivalent amount of which shall be in integral multiples of $1,000,000
and not less than $5,000,000 for each Borrowing Tranche to which the Euro-Rate
Option applies and in integral multiples of $100,000 and not less than the
lesser of $500,000 or the maximum amount available for Borrowing Tranches to
which the Base Rate Option applies; (iii) whether the Euro-Rate Option or Base
Rate Option shall apply to the proposed Loans comprising the applicable
Borrowing Tranche; (iv) the currency in which such Loans shall be funded if the
Borrower is electing the Euro-Rate Option; and (v) in the case of a Borrowing
Tranche to which the Euro-Rate Option applies, an appropriate Interest Period
for the Loans comprising such Borrowing Tranche.

           2.5.2. SWING LOAN REQUESTS.

                  Except as otherwise provided herein, the Borrower may from
time to time prior to the Expiration Date request PNC Bank to make Swing Loans
by delivery to PNC Bank not later than noon Pittsburgh time on the proposed
Borrowing Date of a duly completed request therefor substantially in the form of
EXHIBIT 2.5.2 hereto (each, a "Swing Loan Request"). Each Swing Loan Request
shall be irrevocable and shall specify the proposed Borrowing Date and the
principal amount of such Swing Loan, which shall be in integral multiples of
$500,000 and not less than $1,000,000.

     2.6 MAKING REVOLVING CREDIT LOANS AND SWING LOANS; REVOLVING CREDIT NOTES
AND SWING NOTES.

           2.6.1. MAKING REVOLVING CREDIT LOANS.

                  The Agent shall, promptly after receipt by it of a Loan
Request pursuant to Section 2.5 [Revolving Credit Loan Requests], notify the
Banks of its receipt of such Loan Request specifying: (i) the proposed Borrowing
Date and the time and method of disbursement of the Revolving Credit Loans
requested thereby; (ii) the amount and type of each such Revolving Credit Loan
and the applicable Interest Period (if any); and (iii) the apportionment among
the Banks of such Revolving Credit Loans as determined by the Agent in
accordance with Section 2.3 [Nature of Banks' Obligations]. Each Bank shall
remit the principal amount of each Revolving Credit Loan to the Agent such that
the Agent is able to, and the Agent shall, to the extent the Banks have made
funds available to it for such purpose and subject to Section 7.2 [Each
Additional Loan], fund such Revolving Credit Loans to the Borrower in U.S.
Dollars and immediately available funds at the Principal Office prior to 2:00
p.m., Pittsburgh time, on the applicable Borrowing Date, PROVIDED that if any
Bank fails to remit such funds to the Agent in a timely manner, the Agent may
elect in its sole discretion to fund with its own funds the Revolving Credit
Loans of such Bank on such Borrowing Date, and such Bank shall be subject to the
repayment obligation in Section 10.16 [Availability of Funds].

           2.6.2. MAKING SWING LOANS.

                  So long as PNC Bank elects to make Swing Loans, PNC Bank
shall, after receipt by it of a Swing Loan Request pursuant to Section 2.5.2,
fund such Swing Loan to the Borrower in U.S. Dollars and immediately available
funds at the Principal Office prior to two o'clock p.m. Pittsburgh time on the
Borrowing Date.

     2.7 SWING LOAN NOTE.

     The obligation of the Borrower to repay the unpaid principal amount of the
Swing Loans made to it by PNC Bank together with interest thereon shall be
evidenced by a demand promissory note of the Borrower dated the Closing Date in
substantially the form attached hereto as EXHIBIT 1.1(S)(2) payable to the order
of PNC Bank in a face amount equal to the Swing Loan Commitment.


                                       31
<Page>

     2.8 USE OF PROCEEDS.

     The proceeds of the Revolving Credit Loans shall be used for general
corporate purposes of the Borrower and in accordance with Section 8.1.10 [Use of
Proceeds]; provided, however, that none of the Commitments or the Loans shall be
used for currency speculation or similar purposes.

     2.9 BORROWINGS TO REPAY SWING LOANS.

     PNC may, at its option, exercisable at any time for any reason whatsoever,
demand repayment of the Swing Loans, and each Bank shall make a Revolving Credit
Loan in an amount equal to such Bank's Ratable Share of the aggregate principal
amount of the outstanding Swing Loans, plus, if PNC so requests, accrued
interest thereon, PROVIDED that no Bank shall be obligated in any event to make
Revolving Credit Loans in excess of its Revolving Credit Commitment. Revolving
Credit Loans made pursuant to the preceding sentence shall bear interest at the
Base Rate Option and shall be deemed to have been properly requested in
accordance with Section 2.5.1 without regard to any of the requirements of that
provision. PNC shall provide notice to the Banks that such Revolving Credit
Loans are to be made under this Section 2.9 and of the apportionment among the
Banks, and the Banks shall be unconditionally obligated to fund such Revolving
Credit Loans (whether or not the conditions specified in Section 2.5.1 are then
satisfied) by the time PNC so requests, which shall not be earlier than 3:00
p.m. Pittsburgh time on the Business Day next after the date the Banks receive
such notice from PNC.

     2.10 LETTER OF CREDIT SUBFACILITY.

          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 or
having such other Loan Party deliver 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 11:00 a.m., Pittsburgh time, at least three (3)
Business Days, or such shorter period as may be agreed to by the Agent, in
advance of the proposed date of issuance. Each Letter of Credit shall be a
Standby Letter of Credit (and may not be a Commercial Letter of Credit) and may
be denominated in either Dollars or an Optional Currency. Subject to the terms
and conditions hereof and in reliance on the agreements of the other Banks set
forth in this Section 2.10, the Agent or any of the Agent's Affiliates will
issue a Letter of Credit provided that each Letter of Credit shall (A) have a
maximum maturity of twenty four (24) months from the date of issuance in the
case of the Glenborough Letter of Credit and, in the case of each other Letter
of Credit, shall have a maximum maturity of twelve (12) months from the date of
issuance, (B) in no event expire later than ten (10) Business Days prior to the
Expiration Date and providing that in no event shall (i) the Dollar Equivalent
amount of Letters of Credit Outstanding exceed, at any one time, $15,000,000 or
(ii) the Dollar Equivalent Revolving Facility Usage exceed, at any one time, the
Revolving Credit Commitments and (C) in no event be amended to increase the
amount thereof following the issuance thereof unless the conditions set forth in
Section 7.2 have been satisfied as


                                       32
<Page>

of the date of such amendment (treating such date the same as the date of
issuance of a Letter of Credit). It is expressly agreed that the Existing Letter
of Credit shall be deemed to be a Letter of Credit for all purposes of this
Agreement and each other Loan Document.

          2.10.2. LETTER OF CREDIT FEES.

                  The Borrower shall pay in Dollars (i) to the Agent for the
ratable account of the Banks a fee (the "Letter of Credit Fee") equal to the
Applicable Letter of Credit Fee per annum, and (ii) to the Agent for its own
account a fronting fee equal to 1/8% per annum (computed on the basis of a year
of 360 days and actual days elapsed), which fees shall be computed on the daily
average Dollar Equivalent amount of Letters of Credit Outstanding and shall be
payable quarterly in arrears commencing with the first day of each January,
April, July and October following issuance of each Letter of Credit and on the
Expiration Date. The Borrower shall also pay to the Agent in Dollars for the
Agent's sole account the Agent's then in effect customary fees and
administrative expenses payable with respect to the Letters of Credit as the
Agent may generally charge or incur from time to time in connection with the
issuance, maintenance, modification (if any), assignment or transfer (if any),
negotiation, and administration of Letters of Credit.

          2.10.3. DISBURSEMENTS, REIMBURSEMENT.

                    2.10.3.1 Immediately upon the Issuance of each Letter of
Credit, each Bank 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 Bank'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 in Dollars
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 Dollar Equivalent amount so paid by the Agent. In the event
the Borrower fails to reimburse the Agent for the full Dollar Equivalent 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 Bank thereof, and the Borrower
shall be deemed to have requested that Revolving Credit Loans be made by the
Banks in Dollars 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 7.2 [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.


                                       33
<Page>

                    2.10.3.3 Each Bank shall upon any notice pursuant to Section
2.10.3.2 make available to the Agent an amount in Dollars in immediately
available funds equal to its Ratable Share of the Dollar Equivalent amount of
the drawing, whereupon the participating Banks shall (subject to Section
2.10.3.4) each be deemed to have made a Revolving Credit Loan in Dollars under
the Base Rate Option to the Borrower in that amount. If any Bank so notified
fails to make available in Dollars to the Agent for the account of the Agent the
amount of such Bank's Ratable Share of such Dollar Equivalent amount by no later
than 2:00 p.m., Pittsburgh time on the Drawing Date, then interest shall accrue
on such Bank's obligation to make such payment, from the Drawing Date to the
date on which such Bank 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 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 Bank to effect such payment on such date shall not
relieve such Bank 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 7.2 [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 borrowing (each a
"Letter of Credit Borrowing") in Dollars in the Dollar Equivalent 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 Bank'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 Bank 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 Bank 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 Bank, in the same funds as those received by the Agent,
the amount of such Bank's Ratable Share of such funds, except the Agent shall
retain the amount of the Ratable Share of such funds of any Bank 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 Bank
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


                                       34
<Page>

demand is made to the date such amounts are returned by such Bank
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 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.

          2.10.7. NATURE OF PARTICIPATION AND REIMBURSEMENT OBLIGATIONS.

                  Each Bank's obligation in accordance with this Agreement to
make the Revolving Credit Loans or Participation Advances, as contemplated by
Section 2.10.3, as a result of a drawing under a Letter of Credit, and the
Obligations of the Borrower to reimburse the Agent upon a draw under a Letter of
Credit, shall be absolute, unconditional and irrevocable, and shall be performed
strictly in accordance with the terms of this Section 2.10 under all
circumstances, including the following circumstances:

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

                    (ii) the failure of any Loan Party or any other Person to
comply, in connection with a Letter of Credit Borrowing, with the conditions set
forth in Section 2.1 [Revolving Credit Commitments], 2.5 [Revolving Credit Loan
Requests], 2.5.2 [Making Revolving Credit Loans] or 7.2 [Each Additional Loan]
or as otherwise set forth in this Agreement for the making of a Revolving Credit
Loan, it being acknowledged that such conditions are not required for the making
of a Letter of Credit Borrowing and the obligation of the Banks to make
Participation Advances under Section 2.10.3;

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

                                       35
<Page>

                    (iv) any claim of breach of warranty that might be made by
any Loan Party or any Bank against any beneficiary of a Letter of Credit, or the
existence of any claim, set-off, recoupment, counterclaim, crossclaim, defense
or other right which any Loan Party or any Bank may have at any time against a
beneficiary, successor beneficiary any transferee or assignee of any Letter of
Credit or the proceeds thereof (or any Persons for whom any such transferee may
be acting), the Agent or its Affiliates or any Bank or any other Person or,
whether in connection with this Agreement, the transactions contemplated herein
or any unrelated transaction (including any underlying transaction between any
Loan Party or Subsidiaries of a Loan Party and the beneficiary for which any
Letter of Credit was procured);

                    (v) the lack of power or authority of any signer of (or any
defect in or forgery of any signature or endorsement on) or the form of or lack
of validity, sufficiency, accuracy, enforceability or genuineness of any draft,
demand, instrument, certificate or other document presented under or in
connection with any Letter of Credit, or any fraud or alleged fraud in
connection with any Letter of Credit, or the transport of any property or
provisions of services relating to a Letter of Credit, in each case even if the
Agent or any of the Agent's Affiliates has been notified thereof;

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

                    (vii) the solvency of, or any acts of omissions by, any
beneficiary of any Letter of Credit, or any other Person having a role in any
transaction or obligation relating to a Letter of Credit, or the existence,
nature, quality, quantity, condition, value or other characteristic of any
property or services relating to a Letter of Credit;

                    (viii) any failure by the Agent or any of Agent's Affiliates
to issue any Letter of Credit in the form requested by any Loan Party, unless
the Agent has received written notice from such Loan Party of such failure
within three Business Days after the Agent shall have furnished such Loan Party
a copy of such Letter of Credit and such error is material and no drawing has
been made thereon prior to receipt of such notice;

                    (ix) any adverse change in the business, operations,
properties, assets, condition (financial or otherwise) or prospects of any Loan
Party or Subsidiaries of a Loan Party;

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

                    (xi) the occurrence or continuance of an Insolvency
Proceeding with respect to any Loan Party;

                    (xii) the fact that an Event of Default or a Potential
Default shall have occurred and be continuing;


                                       36
<Page>

                    (xiii) the fact that the Expiration Date shall have passed
or this Agreement or the Commitments hereunder shall have been terminated; and

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

          2.10.8. INDEMNITY.

                  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 and any of Agent's
Affiliates that has issued a Letter of Credit from and against any and all
claims, demands, liabilities, damages, taxes, penalties, interest, judgments,
losses, costs, charges and expenses (including reasonable fees, expenses and
disbursements of counsel and allocated costs of internal counsel) which the
Agent or any of Agent's Affiliates may incur or be subject to as a consequence,
direct or indirect, of the issuance of any Letter of Credit, other than as a
result of (A) the gross negligence, bad faith, or willful misconduct of the
Agent as determined by a final judgment of a court of competent jurisdiction or
(B) the wrongful dishonor by the Agent or any of Agent's Affiliates of a proper
demand for payment made under any Letter of Credit, except if such dishonor
resulted from 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, or the Agent's
Affiliates, 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 any of the following including any losses or
damages to any Loan Party or other Person or property relating therefrom: (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 or the Agent's Affiliates 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, 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


                                       37

consequences arising from causes beyond the control of the Agent or the Agent's
Affiliates, as applicable, including any Governmental Acts, and none of the
above shall affect or impair, or prevent the vesting of, any of the Agent's or
the Agent's Affiliates rights or powers hereunder. Nothing in the preceding
sentence shall relieve the Agent from liability for the Agent's bad faith, gross
negligence or willful misconduct in connection with actions or omissions
described in such clauses (i) through (viii) of such sentence. In no event shall
the Agent or the Agent's Affiliates be liable to any Loan Party for any
indirect, consequential, incidental, punitive, exemplary or special damages or
expenses (including without limitation attorneys' fees), or for any damages
resulting from any change in the value of any property relating to a Letter of
Credit.

                  Without limiting the generality of the foregoing, the Agent
and each of its Affiliates (i) may rely on any oral or other communication
believed in good faith by the Agent or such Affiliate to have been authorized or
given by or on behalf of the applicant for a Letter of Credit, (ii) may honor
any presentation if the documents presented appear on their face substantially
to comply with the terms and conditions of the relevant Letter of Credit; (iii)
may honor a previously dishonored presentation under a Letter of Credit, whether
such dishonor was pursuant to a court order, to settle or compromise any claim
of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to
the same extent as if such presentation had initially been honored, together
with any interest paid by the Agent or its Affiliate; (iv) may honor any drawing
that is payable upon presentation of a statement advising negotiation or
payment, upon receipt of such statement (even if such statement indicates that a
draft or other document is being delivered separately), and shall not be liable
for any failure of any such draft or other document to arrive, or to conform in
any way with the relevant Letter of Credit; (v) may pay any paying or
negotiating bank claiming that it rightfully honored under the laws or practices
of the place where such bank is located; and (vi) may settle or adjust any claim
or demand made on the Agent or its Affiliate in any way related to any order
issued at the applicant's request to an air carrier, a letter of guarantee or of
indemnity issued to a carrier or any similar document (each an "Order") and
honor any drawing in connection with any Letter of Credit that is the subject to
such Order, notwithstanding that any drafts or other documents presented in
connection with such Letter of Credit fail to conform in any way with such
Letter of Credit.

                  In furtherance and extension and not in limitation of the
specific provisions set forth above, any action taken or omitted by the Agent or
the Agent's Affiliates 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 or the Agent's Affiliates under
any resulting liability to the Borrower or any Bank.

     2.11 UTILIZATION OF COMMITMENTS IN OPTIONAL CURRENCIES.

          2.11.1. PERIODIC COMPUTATIONS OF DOLLAR EQUIVALENT AMOUNTS OF LOANS
AND LETTERS OF CREDIT OUTSTANDING.

                  The Agent will determine the Dollar Equivalent amount of (i)
proposed Revolving Credit Loans or Letters of Credit to be denominated in an
Optional Currency as of the requested Borrowing Date or date of issuance, as the
case may be, and


                                       38
<Page>

(ii) outstanding Revolving Credit Loans denominated in an Optional Currency as
of the end of each Interest Period (each such date under clauses (i) and (ii), a
"COMPUTATION DATE").

          2.11.2. NOTICES FROM BANKS THAT OPTIONAL CURRENCIES ARE UNAVAILABLE TO
FUND NEW LOANS.

                  The Banks shall be under no obligation to make the Revolving
Credit Loans requested by the Borrower which are denominated in an Optional
Currency if any Bank notifies the Agent by 5:00 p.m. (Pittsburgh time) four (4)
Business Days prior to the Borrowing Date for such Revolving Credit Loans that
such Bank cannot provide its share of such Revolving Credit Loans in such
Optional Currency due to the introduction of, or any change in, any applicable
Law or any change in the interpretation or administration thereof by any
Official Body charged with the administration or interpretation thereof, or
compliance by such Bank (or any of its lending offices) with any request or
directive (whether or not having the force of Law) of any such Official Body
which would make it unlawful or impossible for such Bank (or any of its lending
offices) to honor its obligations to make a Loan in an Optional Currency. In the
event the Agent timely receives a notice from a Bank pursuant to the preceding
sentence, the Agent will notify the Borrower no later than 12:00 noon
(Pittsburgh time) three (3) Business Days prior to the Borrowing Date for such
Revolving Credit Loans that the Optional Currency is not then available for such
Revolving Credit Loans, and the Agent shall promptly thereafter notify the Banks
of the same. If the Borrower receives a notice described in the preceding
sentence, the Borrower may, by notice to the Agent not later than 5:00 p.m.
(Pittsburgh time) three (3) Business Days prior to the Borrowing Date for such
Revolving Credit Loans, withdraw the Loan Request for such Revolving Credit
Loans. If the Borrower withdraws such Loan Request, the Agent will promptly
notify each Bank of the same and the Banks shall not make such Revolving Credit
Loans. If the Borrower does not withdraw such Loan Request before such time, (i)
the Borrower shall be deemed to have requested that the Revolving Credit Loans
referred to in its Loan Request shall be made in Dollars in an amount equal to
the Dollar Equivalent amount of such Revolving Credit Loans and shall bear
interest under the Base Rate Option, and (ii) the Agent shall promptly deliver a
notice to each Bank stating: (A) that such Revolving Credit Loans shall be made
in Dollars and shall bear interest under the Base Rate Option, (B) the aggregate
amount of such Revolving Credit Loans, and (C) such Bank's Ratable Share of such
Revolving Credit Loans.

          2.11.3. NOTICES FROM BANKS THAT OPTIONAL CURRENCIES ARE UNAVAILABLE TO
FUND RENEWALS OF THE EURO-RATE OPTION.

                  If the Borrower delivers a Loan Request requesting that the
Banks renew the Euro-Rate Option with respect to an outstanding Borrowing
Tranche of Revolving Credit Loans denominated in an Optional Currency, the Banks
shall be under no obligation to renew such Euro-Rate Option if any Bank delivers
to the Agent a notice by 5:00 p.m. (Pittsburgh time) four (4) Business Days
prior to effective date of such renewal that such Bank cannot continue to
provide Revolving Credit Loans in such Optional Currency due to the introduction
of, or any change in, any applicable Law or any change in the interpretation or
administration thereof by any Official Body charged with the administration or
interpretation thereof, or compliance by such Bank (or any of its lending
offices with) any request or directive (whether or


                                       39
<Page>

not having the force of Law) of any such Official Body which would make it
unlawful or impossible for such Bank (or any of its lending offices) to honor
its obligations to make a Loan in an Optional Currency. In the event the Agent
timely receives a notice from a Bank pursuant to the preceding sentence, the
Agent will notify the Borrower no later than 12:00 noon (Pittsburgh time) three
(3) Business Days prior to the renewal date that the renewal of such Revolving
Credit Loans in such Optional Currency is not then available, and the Agent
shall promptly thereafter notify the Banks of the same. If the Agent shall have
so notified the Borrower that any such continuation of Optional Currency Loans
is not then available, any notice of renewal with respect thereto shall be
deemed withdrawn, and such Optional Currency Loans shall be redenominated into
Loans in Dollars subject to the Base Rate Option with effect from the last day
of the Interest Period with respect to any such Optional Currency Loans. The
Agent will promptly notify the Borrower and the Banks of any such
redenomination, and in such notice, the Agent will state the aggregate Dollar
Equivalent amount of the redenominated Optional Currency Loans as of the
Computation Date with respect thereto and such Bank's Ratable Share thereof.

          2.11.4. EUROPEAN MONETARY UNION.

                    2.11.4.1 PAYMENTS IN EUROS UNDER CERTAIN CIRCUMSTANCES.

                  If, as a result of the implementation of the European monetary
union, (i) any Optional Currency ceases to be lawful currency of the nation
issuing the same and is replaced by a European common currency (the "Euro") or
(ii) any Optional Currency and the Euro are at the same time recognized by any
governmental authority of the nation issuing such currency as lawful currency of
such nation and the Agent or the Required Banks shall so request in a notice
delivered to the Borrower, then any amount payable hereunder by any part hereto
in such Optional Currency shall instead by payable in the Euro and the amount so
payable shall be determined by translating the amount payable in such Optional
Currency to the Euro at the exchange rate recognized by the European Central
Bank for the purpose of implementing the European monetary union (and the
provisions governing payments in Optional Currencies in this Agreement shall
apply to such payment in the Euro as if such payment in the Euro were a payment
in an Optional Currency). Prior to the occurrence of the event or events
described in clause (i) or (ii) of the preceding sentence, each amount payable
hereunder in any Optional Currency will, except as otherwise provided herein,
continue to be payable only in that currency.

                    2.11.4.2 ADDITIONAL COMPENSATION UNDER CERTAIN
CIRCUMSTANCES.

                  The Borrower agrees, at the request of any Bank to compensate
such Bank for any loss, cost, expense or reduction in return that such Bank
shall reasonably determine shall be incurred or sustained by such Bank as a
result of the implementation of European monetary union and that would not have
been incurred or sustained but for the transactions provided for herein. A
certificate of any Bank setting forth such Bank's determination of the amount or
amounts necessary to compensate such Bank shall be delivered to the Borrower and
shall be conclusive absent manifest error so long as such determination is made


                                       40
<Page>

on a reasonable basis. The Borrower shall pay such Bank the amount shown as due
on any such certificate within ten (10) days after receipt thereof.

                    2.11.4.3 AMENDMENT TO THIS AGREEMENT.

                  The parties hereto agree, at the time of or at any time
following the implementation of European monetary union, to use reasonable
efforts to enter into an agreement amending this Agreement in order to reflect
the implementation of such monetary union, to permit (if feasible) the Euro to
qualify as an Optional Currency under the terms and conditions of the definition
of such term and to place the parties hereto in the position with respect to the
settlement of payments of the Euro as they would have been with respect to the
settlement of the Optional Currencies it replaced.

          2.11.5. REQUESTS FOR ADDITIONAL OPTIONAL CURRENCIES.

                  The Borrower may deliver to the Agent a written request that
Revolving Credit Loans hereunder also be permitted to be made in any other
lawful currency (other than Dollars), in addition to the currencies specified in
the definition of "Optional Currency" herein provided that such currency must be
freely traded in the offshore interbank foreign exchange markets, freely
transferable, freely convertible into Dollars and available to the Banks in the
applicable interbank market. The Agent will promptly notify the Banks of any
such request promptly after the Agent receives such request. The Agent and each
Bank may grant or accept such request in their sole discretion. The Agent will
promptly notify the Borrower of the acceptance or rejection by the Agent and
each of the Banks of the Borrower's request. The requested currency shall be
approved as an Optional Currency hereunder only if the Agent and all of the
Banks approve of the Borrower's request.

     2.12 CURRENCY REPAYMENTS.

                  Notwithstanding anything contained herein to the contrary, the
entire amount of principal of and interest on any Loan made in an Optional
Currency (including the Euro as provided in Section 2.11.4) shall be repaid in
the same Optional Currency in which such Loan was made, provided, however, that
if it is impossible or illegal for Borrower to effect payment of a Loan in the
Optional Currency in which such Loan was made, or if Borrower defaults in its
obligations to do so, the Required Banks may at their option permit such payment
to be made (i) at and to a different location, subsidiary, affiliate or
correspondent of Agent, or (ii) in the Equivalent Amount of Dollars or (iii) in
an Equivalent Amount of such other currency (freely convertible into Dollars) as
the Required Banks may solely at their option designate. Upon any events
described in (i) through (iii) of the preceding sentence, Borrower shall make
such payment and Borrower agrees to hold each Bank harmless from and against any
loss incurred by any Bank arising from the cost to such Bank of any premium, any
costs of exchange, the cost of hedging and covering the Optional Currency in
which such Loan was originally made, and from any change in the value of
Dollars, or such other currency, in relation to the Optional Currency that was
due and owing. Such loss shall be calculated for the period commencing with the
first day of the Interest Period for such Loan and continuing through the date
of payment


                                       41
<Page>

thereof. Without prejudice to the survival of any other agreement of Borrower
hereunder, Borrower's obligations under this Section 2.12 shall survive
termination of this Agreement.

     2.13 OPTIONAL CURRENCY AMOUNTS.

                  Notwithstanding anything contained herein to the contrary,
Agent may, with respect to notices by Borrower for Loans in an Optional Currency
(including the Euro as provided in Section 2.11.4) or voluntary prepayments of
less than the full amount of an Optional Currency (or the Euro) Borrowing
Tranche, engage in reasonable rounding of the Optional Currency (or the Euro)
amounts requested to be loaned or repaid; and, in such event, Agent shall
promptly notify Borrower and the Banks of such rounded amounts and Borrower's
request or notice shall thereby be deemed to reflect such rounded amounts.

     2.14 RIGHT TO INCREASE REVOLVING CREDIT COMMITMENTS.

                  Provided that there is no Event of Default or Potential
Default, if the Borrower wishes to increase the Revolving Credit Commitments,
the Borrower shall notify the Agent thereof, provided that any such increase
shall be in a minimum of $10,000,000 and the aggregate of all such increases in
the Revolving Credit Commitments shall not exceed $50,000,000 from and after the
Closing Date. Each Bank shall have the right at any time within thirty (30) days
following such notice to increase its respective Revolving Credit Commitment so
as to provide such added commitment pro rata in accordance with such Bank's
Ratable Share, and any portion of such requested increase that is not provided
by any Bank shall: (i) first be available to the other Banks pro rata in
accordance with their Ratable Share, (ii) next be available to the other Banks
in such a manner as the Borrower, the Agent and those Banks shall agree, and
(iii) thereafter, to the extent not provided by the Banks, to any additional
bank proposed by the Borrower, which is approved by the Agent (which approval
shall not be unreasonably withheld) and that becomes a party to this Agreement
pursuant to Section 11.11 [Successors and Assigns]. In the event of any such
increase in the aggregate Revolving Credit Commitments effected pursuant to the
terms of this subsection 2.14, new Revolving Credit Notes shall, to the extent
necessary, be executed and delivered by the Borrower in exchange for the
surrender of the existing Revolving Credit Notes.

                  3. [INTENTIONALLY OMITTED.]

                    4. INTEREST RATES

     4.1 INTEREST RATE OPTIONS.

     The Borrower shall pay interest in respect of the outstanding unpaid
principal amount of the Revolving Credit Loans as selected by it from the Base
Rate Option or Euro-Rate Option set forth below applicable to the Revolving
Credit Loans, 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 Revolving Credit Loans
comprising different Borrowing Tranches and may convert to or renew one or more
Interest Rate Options


                                       42
<Page>

with respect to all or any portion of the Revolving Credit Loans 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
Revolving Credit Loans, and PROVIDED FURTHER that Swing Loans shall bear
interest at such rate, based upon the Base Rate, determined by PNC Bank. If at
any time the designated rate applicable to any Loan made by any Bank exceeds
such Bank's highest lawful rate, the rate of interest on such Bank's Loan shall
be limited to such Bank's highest lawful rate. Interest on the principal amount
of each Loan made in an Optional Currency (or the Euro as provided in Section
2.11.4, shall be paid by the Borrower in such Optional Currency (or the Euro).

          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 (subject to the
provisions above regarding Swing Loans), except that no Loan to which a Base
Rate shall apply may be made in an Optional Currency:

               (i) REVOLVING CREDIT 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 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, provided that, for
Loans made in an Optional Currency for which a 365-day basis is the only market
practice available to the Agent, such rate shall be calculated on the basis of a
year of 365 days, for the actual days) equal to the Euro-Rate plus the
Applicable Margin.

          4.1.2. 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 interest rates
and the applicable currency exchange rates then in effect, but it is
acknowledged that such projection shall not be binding on the Agent or the Banks
nor affect the rate of interest or the calculation of Equivalent Amounts which
thereafter are actually in effect when the election is made.

     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 by delivering a Loan Request
no later than 11:00 a.m. (Pittsburgh time) at least four (4) Business Days prior
to the effective date of such Interest Rate Option, with respect to an Optional
Currency Loan, and three (3) Business Days prior to the effective date of such
Interest Rate Option with respect to a Dollar Loan. The notice shall specify an
Interest Period during which such Interest Rate Option shall apply.


                                       43
<Page>

Notwithstanding the preceding sentence, the following provisions shall apply to
any selection of, renewal of, or conversion to a Euro-Rate Option:

          4.2.1. AMOUNT OF BORROWING TRANCHE.

          the Dollar Equivalent amount of each Borrowing Tranche of Euro-Rate
Loans shall be in integral multiples of $1,000,000 and not less than $5,000,000;
and

          4.2.2. 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. LETTER OF CREDIT FEES, INTEREST RATE.

                 the Letter of Credit Fees and 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 bear
interest at a rate per annum equal to the sum of the rate of interest applicable
under the Rate Option plus an additional two percent (2%) 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 Banks are entitled to 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:


                                       44
<Page>

                    (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 Bank 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 Bank in good faith with the adoption of any change in any Law or any
interpretation or application thereof occurring after the Closing Date 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 Bank of the establishment or maintenance of any such
Loan, or

                    (iii) after making all reasonable efforts, deposits of the
relevant amount in Dollars or in the Optional Currency (as applicable) for the
relevant Interest Period for a Loan, or to banks generally, to which a Euro-Rate
Option applies, respectively, are not available to such Bank with respect to
such Loan, or to banks generally, in the interbank eurodollar market,

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

          4.4.3. AGENT'S AND BANK'S RIGHTS.

                 In the case of any event specified in Section 4.4.1 above, the
Agent shall promptly so notify the Banks and the Borrower thereof, and in the
case of an event specified in Section 4.4.2 above, such Bank shall promptly so
notify the Agent and endorse a certificate to such notice as to the specific
circumstances of such notice, and the Agent shall promptly send copies of such
notice and certificate to the other Banks and the Borrower. Upon such date as
shall be specified in such notice (which shall not be earlier than the date such
notice is given), the obligation of (A) the Banks, in the case of such notice
given by the Agent, or (B) such Bank, in the case of such notice given by such
Bank, to allow the Borrower to select, convert to or renew a Euro-Rate Option or
select an Optional Currency (as applicable) shall be suspended until the Agent
shall have later notified the Borrower, or such Bank shall have later notified
the Agent, of the Agent's or such Bank's, as the case may be, determination 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 the selection of,
conversion to or renewal of the Base Rate Option otherwise available with
respect to such Loans. If any Bank notifies the Agent of a determination under
Section 4.4.2, the Borrower shall, subject to the


                                       45
<Page>

Borrower's indemnification Obligations under Section 5.5.2 [Indemnity], as to
any Loan of the Bank to which a Euro-Rate Option applies, on the date specified
in such notice either (i) as applicable, convert such Loan to the Base Rate
Option otherwise available with respect to such Loan or select a different
Optional Currency or Dollars, or (ii) 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 or Optional
Currency 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 4.2 [Interest Periods], the
Borrower shall be deemed to have converted such Borrowing Tranche to the Base
Rate Option or to a Dollar Loan, as applicable, commencing upon the last day of
the existing Interest Period.

                                   5. PAYMENTS

     5.1 PAYMENTS.

     All payments and prepayments to be made in respect of principal, interest,
Commitment Fees, Letter of Credit Fees, Agent's Fee, Optional Currency Loan
Processing Fees, or other fees or amounts due from the Borrower hereunder shall
be payable prior to 11:00 a.m., Pittsburgh time, on the date when due without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived by the Borrower, and without set-off, counterclaim or other
deduction of any nature, and an action therefor shall immediately accrue. Such
payments shall be made to the Agent at the Principal Office for the account of
PNC Bank with respect to the Swing Loans and for the ratable accounts of the
Banks with respect to the Revolving Credit Loans, in U.S. Dollars except that
payment of principal or interest shall be made in the currency in which such
Loan was made, and in immediately available funds, and the Agent shall promptly
distribute such amounts to the Banks in immediately available funds, PROVIDED
that in the event payments are received by 11:00 a.m., Pittsburgh time, by the
Agent with respect to the Loans and such payments are not distributed to the
Banks on the same day received by the Agent, the Agent shall pay the Banks the
Federal Funds Effective Rate in the case of Loans or other amounts due in
Dollars, or the Overnight Rate in the case of Loans or other amounts due in an
Optional Currency, with respect to the amount of such payments for each day held
by the Agent and not distributed to the Banks. The Agent's and each Bank's
statement of account, ledger or other relevant record shall, in the absence of
manifest error, be conclusive as the statement of the amount of principal of and
interest on the Loans and other amounts owing under this Agreement (including
the Equivalent Amounts of the applicable currencies where such computations are
required) and shall be deemed an "account stated."


                                       46
<Page>

     5.2 PRO RATA TREATMENT OF BANKS.

     Each borrowing of Revolving Credit Loans shall be allocated to each Bank
according to its Ratable Share, and each selection of, conversion to or renewal
of any Interest Rate Option applicable to Revolving Credit Loans and each
payment or prepayment by the Borrower with respect to principal or interest on
the Revolving Credit Loans or Commitment Fees, Letter of Credit Fees, or other
fees (except for the Agent's Fee or the Optional Currency Loan Processing Fee)
or amounts due from the Borrower hereunder to the Banks with respect to the

Bank's Rights] in the case of an event specified in Section 4.4 [Euro-Rate
Unascertainable; Etc.], 5.4.2 [Replacement of a Bank] or 5.5 [Additional
Compensation in Certain Circumstances]) be made in proportion to the applicable
Revolving Credit Loans outstanding from each Bank and, if no such Loans are then
outstanding, in proportion to the Ratable Share of each Bank. Notwithstanding
any of the foregoing, each borrowing or payment or prepayment by the Borrower of
principal, interest, fees or other amounts from the Borrower with respect to
Swing Loans shall be made by or to PNC Bank according to Section 2.

payable in the currency in which such Loan was made on the last day of each
Interest Period for those Loans and, if such Interest Period is longer than
three (3) Months, also on the 90th day of such Interest Period. Interest on

     5.4 VOLUNTARY PREPAYMENTS, MANDATORY PREPAYMENTS.

         5.4.1. RIGHT TO PREPAY.

                The Borrower shall have the right at its option from time to
time to prepay the Revolving Credit Loans in whole or part without premium or
penalty (except as provided in Section 5.4.2 below or in Section 5.5 [Additional
Compensation in Certain Circumstances]) in the currency in which such Loan was
made:

                    (i) at any time with respect to any Revolving Credit Loan to
which the Base Rate Option applies,

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


                                       47
<Page>

                    (iii) on the date specified in a notice by any Bank pursuant
to Section 4.4 [Euro-Rate Unascertainable, Etc.] with respect to any Revolving
Credit Loan to which a Euro-Rate Option applies.

               Whenever the Borrower desires to prepay any part of the Revolving
Credit Loans, it shall provide a prepayment notice to the Agent by 1:00 p.m. (at
least three (3) Business Days prior to the date of prepayment of the Revolving
Credit Loans made in Dollars to which the Euro-Rate Option applies, four (4)
Business Days prior to the date of prepayment of the Revolving Credit Loans made
in an Optional Currency and at least one (1) Business Day prior to the date of
prepayment of the Revolving Credit Loans to which the Base Rate Option applies)
or no later than 1:00 p.m., Pittsburgh time, on the date of prepayment of Swing
Loans, setting forth the following information:

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

          (y) a statement indicating the application of the prepayment between
     the Swing Loans and Revolving Credit Loans; and

          (z) the total principal amount and currency of such prepayment, the
     Dollar Equivalent amount of which shall not be less than $1,000,000 for any
     Swing Loan (or integral multiples of $500,000) or not less than $5,000,000
     (or integral multiples of $1,000,000) for any Revolving Credit Loan subject
     to the Euro-Rate Option, or not less than $500,000 (or integral multiples
     of $100,000) for any Revolving Credit Loan subject to the Base Rate Option.

          All prepayment notices shall be irrevocable. The principal amount of
the Revolving Credit Loans for which a prepayment notice is given, together with
interest on such principal amount except with respect to Revolving Credit 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 in the currency in which such Loan was made. Except as provided in
Section 4.4.3 [Agent's and Bank's rights], if the Borrower prepays a Revolving
Credit 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 to which the Base Rate Option applies, then to Dollar Revolving
Credit Loans to which the Euro-Rate Option applies, and then to Optional
Currency Loans. Any prepayment hereunder shall be subject to the Borrower's
Obligation to indemnify the Banks under Section 5.5.2 [Indemnity].

          5.4.2. REPLACEMENT OF A BANK.

                 In the event any Bank (i) gives notice under Section 4.4
[Euro-Rate Unascertainable, Etc.] or Section 5.5.1 [Increased Costs, Etc.], (ii)
does not fund Revolving Credit Loans because the making of such Loans would
contravene any Law applicable to such Bank, or (iii) 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 Bank in
whole,


                                       48
<Page>

together with all interest accrued thereon, and terminate such Bank's Commitment
within ninety (90) days after (x) receipt of such Bank's notice under Section
4.4 [Euro-Rate Unascertainable, Etc.] or 5.5.1 [Increased Costs, Etc.], (y) the
date such Bank has failed to fund Revolving Credit Loans because the making of
such Loans would contravene Law applicable to such Bank, or (z) the date such
Bank became subject to the control of an Official Body, as applicable; PROVIDED
that the Borrower shall also pay to such Bank at the time of such prepayment any
amounts required under Section 5.5 [Additional Compensation in Certain
Circumstances] and any accrued interest due on such amount and any related fees;
PROVIDED, however, that the Commitment, Revolving Credit Loan of such Bank shall
be provided by one or more of the remaining Banks or a replacement bank
acceptable to the Agent; PROVIDED, further, the remaining Banks 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 Bank 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 5.5.1 [Increased Costs, Etc.] with respect to such Bank,
it will if requested by the Borrower, use reasonable efforts (subject to overall
policy considerations of such Bank) to designate another Lending Office any
Loans or Letters of Credit affected by such event, PROVIDED that such
designation is made on such terms that such Bank 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
in 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 Bank provided
in this Agreement.

          5.4.4. VOLUNTARY REDUCTION OF REVOLVING CREDIT COMMITMENTS.

                 The Borrower shall have the right, upon not less than three (3)
Business Days' written irrevocable notice to the Agent provided no later than
11:00 a.m. on the date such notice is provided, to terminate the Revolving
Credit Commitments or, from time to time, to reduce the amount of the Revolving
Credit Commitments, which notice shall specify the date and amount of any such
reduction and otherwise be substantially in the form of EXHIBIT 5.4.4 (a
"Commitment Reduction Notice"). Any such reduction shall be in a minimum amount
equal to $1,000,000 or an integral multiple thereof, provided, that the
Revolving Credit Commitments may not be reduced below the aggregate principal
amount of all Dollar Equivalent Revolving Facility Usage. Each reduction of
Revolving Credit Commitments shall ratably reduce the Revolving Credit
Commitments of the Banks.

          5.4.5. APPLICATION AMONG INTEREST RATE OPTIONS.

                 All prepayments pursuant to this Section 5.4 shall first be
applied among the Interest Rate Options to the principal amount of the Loans
subject to the Base Rate Option, then to Dollar Loans subject to a Euro-Rate
Option and then to Optional Currency Loans. In accordance with Section 5.5.2
[Indemnity], the Borrower shall indemnify the Banks for any


                                       49
<Page>

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.

          5.4.6. MANDATORY PREPAYMENT - CURRENCY FLUCTUATIONS.

                 If on any Computation Date the Dollar Equivalent Revolving
Facility Usage is equal to or greater than 100% of the Commitments as a result
of a change in exchange rates between one (1) or more Optional Currencies and
Dollars, then the Agent shall notify the Borrower of the same. The Borrower
shall pay or prepay the Loans (subject to Borrower's indemnity obligations under
Sections 5.4 and 5.5) within one (1) Business Day after receiving such notice
such that the Dollar Equivalent Revolving Facility Usage shall not exceed the
aggregate Commitments after giving effect to such payments or prepayments.

     5.5 ADDITIONAL COMPENSATION IN CERTAIN CIRCUMSTANCES.


          5.5.1. INCREASED COSTS OR REDUCED RETURN RESULTING FROM TAXES,
RESERVES, CAPITAL ADEQUACY REQUIREMENTS, EXPENSES, ETC.

                 If the adoption of any Law, guideline or interpretation or any
change in any Law, guideline or interpretation or application thereof (in each
case occurring after the date hereof or, in the case of an assignment or
transfer, after the date of such assignment or transfer) by any Official Body
charged with the interpretation or administration thereof or compliance with any
request or directive (whether or not having the force of Law) of any central
bank or other Official Body:

                    (i) subjects any Bank to any tax or changes the basis of
taxation with respect to this Agreement, the 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, or measured by, the overall
net income of such Bank),

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

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Bank or its Lending Office with respect to this Agreement, the Notes or the
making, maintenance or funding of any part of the Loans (or, in the case of any
capital adequacy or similar requirement, to have the effect of reducing the rate
of return on any Bank's capital, taking into consideration such Bank's customary
policies with respect to capital adequacy) by an amount which such Bank in its
reasonable


                                       50
<Page>

discretion deems to be material, such Bank shall from time to time notify the
Borrower and the Agent of the amount reasonably determined in good faith (using
any averaging and attribution methods employed in good faith) by such Bank to be
necessary to compensate such Bank 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 Bank ten (10) Business Days after
such notice is given.

          5.5.2. INDEMNITY.

                 In addition to the compensation required by Section 5.5.1
[Increased Costs, Etc.], the Borrower shall indemnify each Bank against all
liabilities, losses or 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 Bank to fund or maintain
Loans subject to a Euro-Rate Option) which such Bank 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 4.2 [Interest Periods]
or notice relating to prepayments under Section 5.4 [Voluntary Prepayments] or
any Swing Loan Requests under Section 2.5.2 [Swing Loan Requests] or any
requests under Section 2.11 [Right to Increase Revolving Credit Commitments] or
any request under Section 5.4.4 [Voluntary Reduction of Revolving Credit
Commitments],

                    (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 of or interest on the Loans, Commitment
Fee or any other amount due hereunder.

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

     5.6 INTERBANK MARKET PRESUMPTION.

                 For all purposes of this Agreement and each Note with respect
to any aspects of the Euro-Rate, any Loan under the Euro-Rate Option or any
Optional Currency,


                                       51
<Page>

each Bank and Agent shall be presumed to have obtained rates, funding,
currencies, deposits, and the like in the applicable interbank market regardless
whether it did so or not; and, each Bank's and Agent's determination of amounts
payable under, and actions required or authorized by, Sections 4.4 and 5.5 shall
be calculated, at each Bank's and Agent's option, as though each Bank and Agent
funded each Borrowing Tranche of Loans under the Euro-Rate Option through the
purchase of deposits of the types and maturities corresponding to the deposits
used as a reference in accordance with the terms hereof in determining the
Euro-Rate applicable to such Loans, whether in fact that is the case.

     5.7 TAXES.

          5.7.1. NO DEDUCTIONS.

                 All payments made by Borrower hereunder and under each Note
shall be made free and clear of and without deduction for any present or future
taxes, levies, imposts, deductions, charges, or withholdings, and all
liabilities with respect thereto, excluding taxes imposed on or measured by the
net income of any Bank and all income and franchise taxes applicable to any Bank
(all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings, and liabilities being hereinafter referred to as "TAXES"). If
Borrower shall be required by Law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note, (i) the sum payable shall be increased
as may be necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 5.7.1) each
Bank receives an amount equal to the sum it would have received had no such
deductions been made, (ii) Borrower shall make such deductions and (iii)
Borrower shall timely pay the full amount deducted to the relevant tax authority
or other authority in accordance with applicable Law.

          5.7.2. STAMP TAXES.

                 In addition, Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges, or similar
levies which arise from any payment made hereunder or from the execution,
delivery, or registration of, or otherwise with respect to, this Agreement or
any Note, excluding taxes imposed on, or measured by, the net income of any Bank
and all income and franchise taxes applicable to any Bank (hereinafter referred
to as "Other Taxes").

          5.7.3. INDEMNIFICATION FOR TAXES PAID BY A BANK.

                 Borrower shall indemnify each Bank for the full amount of Taxes
or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed
by any jurisdiction on amounts payable under this Section 5.7.3) paid by any
Bank and any liability (including penalties, interest, and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted. This indemnification shall be made within 30 days
from the date a Bank makes written demand therefor.


                                       52
<Page>

          5.7.4. CERTIFICATE.

                 Within 30 days after the date of any payment of any Taxes by
Borrower, Borrower shall furnish to each Bank, at its address referred to
herein, the original or a certified copy of a receipt evidencing payment
thereof. If no Taxes are payable in respect of any payment by Borrower, such
Borrower shall, if so requested by a Bank, provide a certificate of an officer
of Borrower to that effect.

          5.7.5. EXCEPTION FOR CERTAIN TAXES AND OTHER TAXES

                 The Borrower shall not be required to pay any additional
amounts to any Bank in respect of Taxes or Other Taxes if the obligation to pay
such additional amounts would not have arisen but for (i) such Bank being
treated as a "conduit entity" within the meaning of section 1.881-3 of the
Treasury Regulations (or any successor provision thereto) but only if the
"financing entity" (within the meaning of the same Treasury Regulations) is
"related to" such Bank (also within the meaning of the same Treasury
Regulations), or (ii) a failure of such Bank to comply with the provisions of
section 11.17.1 hereof relating to the time and manner for furnishing
Withholding Certificates (including, without limitation, any such failure caused
by such Bank's inability to qualify for a total exemption or reduced rate of
withholding due to an event, factor or circumstance within the reasonable
control of such Bank), provided that this clause (ii) shall not apply in the
event any such failure is caused by a change in applicable treaty, law, or
regulation, or a change in official position regarding the application or
interpretation thereof, in each case after the date hereof (and, in the case of
an assignment or transfer, the date thereof).

          5.7.6. REFUND.

                 If the Agent or any Bank determines, in its reasonable
discretion, that it has received a refund or credit in respect of any Taxes or
Other Taxes as to which it has been indemnified by the Borrower or with respect
to which the Borrower has paid additional amounts pursuant to this Section 5.7,
it shall as promptly as reasonably possible pay over such refund or credit to
the Borrower (but only to the extent of indemnity payments made, or additional
amounts paid, by the Borrower under this Section 5.7 with respect to the Taxes
or Other Taxes giving rise to such refund or credit), net of all out-of-pocket
expenses of the Agent or such Bank and without interest (other than any interest
paid by the relevant Official Body with respect to such refund or credit);
PROVIDED, that the Borrower, upon the request of the Agent or such Bank, agrees
to repay the amount paid over to the Borrower (plus any penalties, interest or
other charges imposed by the relevant Official Body) to the Agent or such Bank
in the event the Agent or such Bank is required to repay such refund to such
Official Body. This paragraph shall not be construed to require the Agent or any
Bank to make available its tax returns (or any other information relating to its
taxes which it deems confidential) to the Borrower or any other Person.


                                       53
<Page>

          5.7.7. SURVIVAL.

                 Without prejudice to the survival of any other agreement of
Borrower hereunder, the agreements and obligations of Borrower contained in
Sections 5.7.1 through 5.7.7 shall survive the payment in full of principal and
interest hereunder and under any instrument delivered hereunder.

     5.8 NOTES.

     Upon the request of any Bank, the Revolving Credit Loans made by such Bank
may be evidenced by a Revolving Credit Note, dated the Closing Date and in an
amount equal to the Revolving Credit Commitment of such Bank, in the form of
EXHIBIT 1.1(R).

     5.9 SETTLEMENT DATE PROCEDURES.

     In order to minimize the transfer of funds between the Banks and the Agent,
the Borrower may borrow, repay and reborrow Swing Loans and PNC Bank may make
Swing Loans as provided in Section 2.2.1 hereof. On any Business Day, the Agent
may notify each Bank of its Ratable Share of the total of the Revolving Credit
Loans and the Swing Loans (each a "Required Share"). Prior to 2:30 p.m.
(Pittsburgh time) on the date of such notice, each Bank 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 Bank 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, on any date
where payments of principal of any Loan is required to be paid by any Loan Party
hereunder, and may at its option (and in consultation with the Borrower) 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 5.9 shall relieve the Banks of their obligations to
fund Revolving Credit Loans on dates other than a Settlement Date pursuant to
Section 2.9. The Agent may at any time at its option for any reason whatsoever
require each Bank to pay immediately to the Agent such Bank's Ratable Share of
the outstanding Revolving Credit Loans and each Bank may at any time require the
Agent to pay immediately to such Bank its Ratable Share of all payments made by
the Borrower to the Agent with respect to the Revolving Credit Loans.

     5.10 JUDGMENT CURRENCY.

          5.10.1. CURRENCY CONVERSION PROCEDURES FOR JUDGMENTS.

                  If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due hereunder or under a Note in any currency (the
"Original Currency") into another currency (the "Other Currency"), the parties
hereby agree, to the fullest extent permitted by Law, that the rate of exchange
used shall be that at which in accordance with normal banking procedures each
Bank could purchase the Original Currency with the Other Currency after any
premium and costs of exchange on the Business Day preceding that on which final
judgment is given.


                                       54
<Page>

          5.10.2. INDEMNITY IN CERTAIN EVENTS.

                  The obligation of Borrower in respect of any sum due from
Borrower to any Bank hereunder shall, notwithstanding any judgment in an Other
Currency, whether pursuant to a judgment or otherwise, be discharged only to the
extent that, on the Business Day following receipt by any Bank of any sum
adjudged to be so due in such Other Currency, such Bank may in accordance with
normal banking procedures purchase the Original Currency with such Other
Currency. If the amount of the Original Currency so purchased is less than the
sum originally due to such Bank in the Original Currency, Borrower agrees, as a
separate obligation and notwithstanding any such judgment or payment, to
indemnify such Bank against such loss.

                         6. REPRESENTATIONS AND WARRANTIES

          8.1.2.  PAYMENT OF LIABILITIES, INCLUDING TAXES, ETC.

                  Each Loan Party shall, and shall cause each of its

<Page>

promptly as and when the same shall become due and payable, including all taxes,
assessments and governmental charges upon it or any of its properties, assets,
income or profits, prior to the date on which penalties attach thereto, except
to the extent that such liabilities, including taxes, assessments or charges,
are being contested in good faith and by appropriate and lawful proceedings
diligently conducted and for which such reserve or other appropriate provisions,
if any, as shall be required by GAAP shall have been made, but only to the
extent that failure to discharge any such liabilities would not be reasonably
expected to result in a Material Adverse Effect.

          8.1.3.  MAINTENANCE OF INSURANCE.

businesses of similar character and size, all of those properties useful or
necessary to its business, and from time to time, such Loan Party will make or
cause to be made all appropriate repairs, renewals or replacements thereof.

Subsidiaries to, maintain in full force and effect all patents, trademarks,

authorizations necessary for the ownership and operation of its properties and
business if the failure so to maintain the same would reasonably be expected to
constitute a Material Adverse Effect.

          8.1.6.  VISITATION RIGHTS.

                  Upon reasonable prior notice to the Borrower and the Agent and
during normal business hours and in a manner that will not interfere with its

properties and to examine and make excerpts from its books and records and
discuss its business affairs, finances and accounts with its officers, all in

request. In the event any Bank desires to conduct an audit of any Loan Party,
such Bank shall make a reasonable effort to conduct such audit contemporaneously
with any audit to be performed by the Agent.

reasonably be expected to result in a Material Adverse Effect. Without limiting
the generality of the foregoing, the Borrower shall cause all of its Plans and
all Plans maintained by any member of the ERISA Group to be funded in accordance
with the minimum funding requirements of ERISA and shall make, and cause each
member of the ERISA Group to make, in a timely manner, all contributions due to

                  Each Loan Party shall, and shall cause each of its
Subsidiaries to, comply with all applicable Laws, including all Environmental
Laws and all Safety Laws, in all respects, PROVIDED that it shall not be deemed
to be a violation of this Section 8.1.9 if any failure to comply with any Law

Letters of Credit and related transactions as being a "reportable transaction"

of the Loan Parties determines to take any action inconsistent with such
intention, the Borrower will promptly (1) notify the Agent thereof, and (2)
deliver to the Agent a duly completed copy of IRS Form 8886 or any successor
form. If the Borrower so notifies the Agent, the Borrower acknowledges that one
or more of the Banks may treat its Loans and/or Letters of Credit as part of a
transaction that is subject to Treasury Regulation Section 301.6112-1, and such
Bank or Banks, as applicable, will maintain the lists and other records required
by such Treasury Regulation.

property blocked pursuant to the Executive Order No. 13224; or (iii) engage in

purpose of evading or avoiding, or attempts to violate, any of the prohibitions
set forth in the Executive Order No. 13224, the USA Patriot Act or any other
Anti-Terrorism Law, except where the failure to do so is not reasonably likely
to constitute a Material Adverse Effect or expose the Agent or any Bank to
liability. The Borrower shall deliver to Banks any certification or other
evidence reasonably requested from time to time by any Bank in its sole
discretion, confirming Borrower's compliance with this Section 8.1.13.

          8.1.14. FURTHER ASSURANCES.

in the Pledged Collateral as a continuing first priority perfected Liens and
shall do such other acts and things as the Agent in its sole discretion may deem

the foregoing.

          9.2.1. EVENTS OF DEFAULT OTHER THAN BANKRUPTCY, INSOLVENCY OR
REORGANIZATION PROCEEDINGS.

                  If an Event of Default specified under Sections 9.1.1 through
9.1.13 shall occur and be continuing, the Banks and the Agent shall be under no
further obligation to make Revolving Credit Loans or issue Letters of Credit, as
the case may be, and the Agent may, and upon the request of the Required Banks,
shall by written notice to the Borrower, take one or both of the following
actions: (i) terminate the Commitments and thereupon the Commitments shall be
terminated and of no further force and effect, or (ii) declare the unpaid
principal amount of the Revolving Credit Loans then outstanding and all interest
accrued thereon, any unpaid fees and all other Indebtedness of the Borrower to
the Banks hereunder and thereunder to be forthwith due and payable, and the same
shall thereupon become and be immediately due and payable to the Agent for the
benefit of each Bank without presentment, demand, protest or any other notice of
any kind, all of which are hereby expressly waived, and (ii) require the
Borrower to, and the Borrower shall thereupon, deposit in a non-interest-bearing
account with the Agent, as cash collateral for its Obligations under the Loan
Documents, an amount equal to the maximum amount currently or at any time
thereafter available to be drawn on all outstanding Letters of Credit, and the
Borrower hereby pledges to the Agent and the Banks, and grants to the Agent and
the Banks a security interest in, all such cash as security for such
Obligations. Upon the curing of all existing Events of Default to the
satisfaction of the Required Banks, the Agent shall return such cash collateral
to the Borrower; and

          9.2.2. BANKRUPTCY, INSOLVENCY OR REORGANIZATION PROCEEDINGS.

               If an Event of Default specified under Section 9.1.14
[Involuntary Proceedings] or 9.1.15 [Voluntary Proceedings] shall occur, the
Commitments shall automatically terminate and be of no further force and effect,
the Banks shall be under no further


                                       85
<Page>

obligations to make Revolving Credit Loans hereunder, PNC Bank shall be under no
further obligation to make Swing Loans hereunder and the unpaid principal amount
of the Loans then outstanding and all interest accrued thereon, any unpaid fees
and all other Indebtedness of the Borrower to the Banks hereunder and thereunder
shall be immediately due and payable, without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived; and

          9.2.3. SET-OFF.

               If an Event of Default shall occur and be continuing, any Bank to
whom any Obligation is owed by any Loan Party hereunder or under any other Loan
Document or any participant of such Bank which has agreed in writing to be bound
by the provisions of Section 10.13 [Equalization of Banks] and any branch,
Subsidiary or Affiliate of such Bank or participant anywhere in the world shall
have the right, in addition to all other rights and remedies available to it,
without notice to such Loan Party, to set-off against and apply to the then
unpaid balance of all the Loans and all other Obligations of the Borrower and
the other Loan Parties hereunder or under any other Loan Document any debt owing
to, and any other funds held in any manner for the account of, the Borrower or
such other Loan Party by such Bank or participant or by such branch, Subsidiary
or Affiliate, including all funds in all deposit accounts (whether time or
demand, general or special, provisionally credited or finally credited, or
otherwise) now or hereafter maintained by the Borrower or such other Loan Party
for its own account (but not including funds held in custodian or trust
accounts) with such Bank or participant or such branch, Subsidiary or Affiliate.
Such right shall exist whether or not any Bank or the Agent shall have made any
demand under this Agreement or any other Loan Document, whether or not such debt
owing to or funds held for the account of the Borrower or such other Loan Party
is or are matured or unmatured and regardless of the existence or adequacy of
any Guaranty, any Pledged Collateral or any other security, right or remedy
available to any Bank or the Agent; and

          9.2.4. SUITS, ACTIONS, PROCEEDINGS.

                  If an Event of Default shall occur and be continuing, and
whether or not the Agent shall have accelerated the maturity of the Loans
pursuant to any of the foregoing provisions of this Section 9.2, the Agent or
any Bank, if owed any amount with respect to the Loans, may proceed to protect
and enforce its rights by suit in equity, action at law and/or other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in this Agreement or the other Loan Documents, including as permitted
by applicable Law the obtaining of the EX PARTE appointment of a receiver, and,
if such amount shall have become due, by declaration or otherwise, proceed to
enforce the payment thereof or any other legal or equitable right of the Agent
or such Bank; and

          9.2.5. APPLICATION OF PROCEEDS; COLLATERAL SHARING.

                    9.2.5.1 APPLICATION OF PROCEEDS.

                    From and after the date on which the Agent has taken any
action pursuant to this Section 9.2 and until all Obligations of the Loan
Parties have been paid in full,


                                       86
<Page>

any and all proceeds received by the Agent from any sale or other disposition of
the Pledged Collateral, or any part thereof, or the exercise of any remedy by
the Agent, shall be applied as follows:

                    (i) first, to reimburse the Agent and the Banks for
out-of-pocket costs, expenses and disbursements, including reasonable attorneys'
and paralegals' fees and legal expenses, incurred by the Agent or the Banks in
connection with realizing on the Pledged Collateral or collection of any
Obligations of any of the Loan Parties under any of the Loan Documents,
including advances made by the Agent or the Banks for the reasonable
maintenance, preservation, protection or enforcement of, or realization upon,
the Pledged Collateral, including advances for taxes, insurance, repairs and the
like and reasonable expenses incurred to sell or otherwise realize on, or
prepare for sale or other realization on, any of the Pledged Collateral.

                    (ii) second, to the repayment of all Indebtedness then due
and unpaid of the Loan Parties to the Banks incurred under this Agreement or any
of the other Loan Documents or a Bank-Provided Hedge or the B of A/Glenborough
Letter of Credit (but only if Bank of America is a Bank hereunder), whether of
principal, interest, fees, expenses or otherwise, in such manner as the Agent
may determine in its discretion; and

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

                    9.2.5.2 COLLATERAL SHARING.

                    All Liens granted under any Loan Document (the "Collateral
Documents") shall secure ratably and on a pari passu basis (i) the Obligations
in favor of the Agent and the Banks hereunder, (ii) the Obligations incurred by
any of the Loan Parties in favor of any Bank which provides a Bank-Provided
Hedge (the "IRH Provider"), and (iii) the Obligations incurred by any of the
Loan Parties in favor of Bank of America (but only if it is a Bank hereunder)
("Bank of America") under the B of A/Glenborough Letter of Credit. The Agent
under the Collateral Documents shall be deemed to serve as the collateral agent
(the "Collateral Agent") for the IRH Provider, Bank of America (but only if it
is a Bank hereunder and only as it relates to Obligations incurred by the Loan
Parties in favor of Bank of America under the B of A/Glenborough Letter of
Credit) and the Banks hereunder, provided that the Collateral Agent shall comply
with the instructions and directions of the Agent (or the Banks under this
Agreement to the extent that this Agreement or any other Loan Documents empowers
the Banks to direct the Agent), as to all matters relating to the collateral
under the Collateral Documents, including the maintenance and disposition
thereof. No IRH Provider (except in its capacity as a Bank hereunder) shall be
entitled or have the power to direct or instruct the Collateral Agent on any
such matters or to control or direct in any manner the maintenance or
disposition of the collateral under the Collateral Documents. Bank of America
(except in its capacity as a Bank hereunder) shall not be entitled or have the
power to direct or instruct the Collateral Agent on any such matters or to
control or direct in any manner the maintenance or disposition of the collateral
under the Collateral Documents.

          9.2.6. OTHER RIGHTS AND REMEDIES.

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

          9.2.7. NOTICE OF SALE.

                  Any notice required to be given by the Agent or any Bank of a
sale, lease, or other disposition of the Pledged Collateral or any other
intended action by the Agent or any Bank, if given ten (10) days prior to such
proposed action, shall constitute commercially reasonable and fair notice
thereof to the Loan Parties.

                                 10. THE AGENT

     10.1 APPOINTMENT.

     Each Bank hereby irrevocably designates, appoints and authorizes PNC Bank
to act as Agent for such Bank under this Agreement and to execute and deliver or
accept on behalf of each of the Banks the other Loan Documents. Each Bank hereby
irrevocably authorizes, 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 Banks
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 [Exculpatory Provisions, Etc.], 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 Bank; and nothing in this
Agreement, expressed or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in


                                       88
<Page>

respect of this Agreement except as expressly set forth herein. Without
limiting the generality of 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 Bank expressly acknowledges (i) that the
Agent has not made any representations or warranties to it and that no act by
the Agent hereafter taken, including any review of the affairs of any of the
Loan Parties, shall be deemed to constitute any representation or warranty by
the Agent to any Bank; (ii) that it has made and will continue to make, without
reliance upon the Agent, its own independent investigation of the financial
condition and affairs and its own appraisal of the creditworthiness of 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 Bank 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 BANKS.

     The Agent agrees, upon the written request of the Required Banks, 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 Banks, 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 Banks or
all of the Banks. Any action taken or failure to act pursuant to such
instructions or discretion shall be binding on the Banks, subject to Section
10.6 [Exculpatory Provisions, Etc.]. Subject to the provisions of Section 10.6,
no Bank shall have any right of action whatsoever against the Agent as a result
of the Agent acting or refraining from acting hereunder in accordance with the
instructions of the Required Banks, or in the absence of such instructions, in
the absolute discretion of the Agent.

     10.5 REIMBURSEMENT AND INDEMNIFICATION OF AGENT BY THE BORROWER.

     The Borrower unconditionally agrees to pay or reimburse the Agent and hold
the Agent harmless against (a) liability for the payment of all reasonable
out-of-pocket costs, expenses and disbursements, including reasonable fees and
expenses of counsel (including, without duplication of legal work of outside
counsel, the allocated costs of staff counsel), appraisers and environmental
consultants, incurred by the Agent (i) in connection with the development,
negotiation, preparation, printing, execution, administration, syndication,
interpretation and performance of this Agreement and the other Loan Documents,
(ii) relating to any requested amendments, waivers or consents pursuant to the
provisions hereof, (iii) 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, (iv) in any workout or restructuring or in connection with the
protection, preservation,


                                       89
<Page>

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, and (v) in connection with any Environmental
Complaint threatened or asserted against the Agent or the Lenders in any way
relating to or arising out of this Agreement or any other Loan Documents
(including, without limitation, 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 in any workout or restructuring) 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 (i) this Agreement or any other Loan
Documents or any action taken or omitted by the Agent hereunder or thereunder
and (ii) any Environmental Complaint 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 bad faith, 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 Bank 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 bad faith,
gross negligence or willful misconduct, (b) be responsible in any manner to any
of the Banks 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 Banks 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 Bank, the Agent or any of their respective Subsidiaries against the
Agent, any Bank 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


                                       90
<Page>

Parties, (for itself and on behalf of each of its Subsidiaries), the
Agent and each Bank 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 Bank
agrees that, except for notices, reports and other documents expressly required
to be furnished to the Banks by the Agent hereunder or given to the Agent for
the account of or with copies for the Banks, the Agent and each of its
directors, officers, employees, agents, attorneys or Affiliates shall not have
any duty or responsibility to provide any Bank with any credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of the Loan Parties 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 BANKS.

     Each Bank 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
(including the allocated reasonable costs of staff counsel), 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 Bank shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements (a) if the same results from the Agent's gross
negligence or willful misconduct, or (b) if such Bank was not given notice of
the subject claim and the opportunity to participate in the defense thereof, at
its expense (except that such Bank shall remain liable to the extent such
failure to give notice does not result in a loss to the Bank), or (c) if the
same results from a compromise and settlement agreement entered into without the
consent of such Bank, which shall not be unreasonably withheld. In addition,
each Bank agrees promptly upon demand to reimburse the Agent (to the extent not
reimbursed by the Borrower and without limiting the Obligation of the Borrower
to do so) in proportion to its Ratable Share for all amounts due and payable by
the Borrower to the Agent in connection with the Agent's periodic audit of the
Loan Parties' books, records and business properties.

     10.8 RELIANCE BY AGENT.

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


                                       91
<Page>

     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 Bank or the Borrower referring to this Agreement,
describing such Potential Default or Event of Default and stating that such
notice is a "notice of default".

     10.10 NOTICES.

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

     10.11 BANKS IN THEIR INDIVIDUAL CAPACITIES; AGENTS IN ITS INDIVIDUAL
CAPACITY.

     With respect to its Revolving Credit Commitment and the Revolving Credit
Loans made by it and any other rights and powers given to it as a Bank hereunder
or under any of the other Loan Documents, the Agent shall have the same rights
and powers hereunder as any other Bank and may exercise the same as though it
were not the Agent, and the term "Bank" and "Banks" shall, unless the context
otherwise indicates, include the Agent in its individual capacity. PNC Bank and
its Affiliates and each of the Banks and their respective Affiliates may,
without liability to account, except as prohibited herein, make loans to, issue
letters of credit for the account of, acquire equity interests in, accept
deposits from, discount drafts for, act as trustee under indentures of, and
generally engage in any kind of banking, trust, financial advisory, underwriting
or other 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 Bank, as though such Bank were not a Bank hereunder, in each case without
notice to or consent of the other Banks. The Banks acknowledge that, pursuant to
such activities, the Agent or its Affiliates may (i) receive information
regarding the Loan Parties or any of their Subsidiaries or Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Loan Parties or such Subsidiary or Affiliate) 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 Banks.

     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.


                                       92

     10.13 EQUALIZATION OF BANKS.

     The Banks and the holders of any participations in any Commitments or Loans
or other rights or obligations of a Bank hereunder agree among themselves that,
with respect to all amounts received by any Bank or any such holder for
application on any Obligation hereunder or under any 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 Banks and such holders in proportion to their interests in
payments on the Loans, except as otherwise provided in Section 4.4.3 [Agent's
and Bank's Rights], 5.4.2 [Replacement of a Bank] or 5.5 [Additional
Compensation in Certain Circumstances]. The Banks or any such holder receiving
any such amount shall purchase for cash from each of the other Banks an interest
in such Bank's Loans in such amount as shall result in a ratable participation
by the Banks and each such holder in the aggregate unpaid amount of the Loans,
PROVIDED that if all or any portion of such excess amount is thereafter
recovered from the Bank or the holder making such purchase, such purchase shall
be rescinded and the purchase price restored to the extent of such recovery,
together with interest or other amounts, if any, required by law (including
court order) to be paid by the Bank or the holder making such purchase.

     10.14 SUCCESSOR AGENT.

     The Agent (i) may resign as Agent or (ii) shall resign if such resignation
is requested by the Required Banks (if the Agent is a Bank, the Agent's Loans
and its Commitment shall be considered in determining whether the Required Banks
have requested such resignation) or required by Section 5.4.2 [Replacement of a
Bank], 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 Banks shall appoint from among the Banks
a successor agent for the Banks, subject to the consent of the Borrower, such
consent not to be unreasonably withheld or delayed, or (b) if a successor agent
shall not be so appointed and approved within the thirty (30) day period
following the Agent's notice to the Banks of its resignation, then the Agent
shall appoint, with the consent of the Borrower, such consent not to be
unreasonably withheld or delayed, a successor agent who shall serve as Agent
until such time as the Required Banks 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.


                                       93

     10.15 AGENT'S FEE.

     The Borrower shall pay to the Agent a nonrefundable fee (the "Optional
Currency Loan Processing Fee") in connection with processing Revolving Credit
Loans denominated in any Optional currency and 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 Bank has made or will make the proceeds of a
Revolving Credit Loan available to the Agent in the applicable currency unless
the Agent shall have been notified by such Bank 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 Banks and whether such funding occurs before or after the time on which
Banks are required to deposit the proceeds of such Loan with the Agent). The
Agent may, in reliance upon such assumption (but shall not be required to), make
available to the Borrower a corresponding amount in the applicable currency. If
such corresponding amount is not in fact made available to the Agent by such
Bank in the applicable currency, the Agent shall be entitled to recover such
amount on demand from such Bank (or, if such Bank fails to pay such amount
forthwith upon such demand from the Borrower) 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 Bank whether
in respect of the Loans, fees or any other amounts due to the Banks under this
Agreement. In the event an error in computing any amount payable to any Bank is
made, the Agent, the Borrower and each affected Bank shall, forthwith upon
discovery of such error, make such adjustments as shall be required to correct
such error, and any compensation therefor will be calculated at the Federal
Funds Effective Rate or the Overnight Rate if such computation relates to a Loan
made in an Optional Currency.

     10.18 BENEFICIARIES.

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

     10.19 NO RELIANCE ON AGENT'S CUSTOMER IDENTIFICATION PROGRAM.

     Each Bank acknowledges and agrees that neither such Bank, nor any of its
Affiliates, participants or assignees, may rely on the Agent to carry out such
Bank's, Affiliate's, participant's or assignee's customer identification
program, or other obligations required or imposed under or pursuant to the USA
Patriot Act or the regulations thereunder, including the regulations contained
in 31 CFR 103.121 (as hereafter amended or replaced, the "CIP Regulations"), or
any other Anti-Terrorism Law, including any programs involving any of the
following items relating to or in connection with any of the Loan Parties, their
Affiliates or their agents, the Loan Documents or the transactions hereunder or
contemplated hereby: (1) any identity verification procedures, (2) any
recordkeeping, (3) comparisons with government lists, (4) customer notices or
(5) other procedures required under the CIP Regulations or such other Laws.

     10.20 CERTAIN RELEASES OF PLEDGED COLLATERAL.

     It is expressly agreed by each Bank, that upon the written request of the
Borrower (accompanied by such certificates and other documentation as the Agent
may reasonably request) the Agent on behalf of the Banks and without any consent
or action by any Bank, may, so long as no Event of Default exists after giving
effect thereto, release any portion of the Pledged Collateral in connection with
any sale, transfer, lease, disposition, merger or other transaction permitted by
this Agreement; provided, however, that the provisions set forth in this Section
10.20 apply only to releases of portions of the Pledged Collateral where this
Agreement does not otherwise expressly provide for the consent or approval of
all Banks. (By way of example, the provisions of this Section 10.20 would not
apply to any release of all or substantially all of the Pledged Collateral,
which release, in accordance with Section 11.1.3 [Release of Collateral or
Guarantor], would require the consent of all of the Banks).

                                 11. MISCELLANEOUS

     11.1 MODIFICATIONS, AMENDMENTS OR WAIVERS.

     With the written consent of the Required Banks, the Agent, acting on behalf
of all the Banks, and the 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 Banks 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 Banks and the Loan Parties;
PROVIDED, that, no such agreement, waiver or consent may be made which will:

          11.1.1. INCREASE OF COMMITMENT; EXTENSION OF EXPIRATION DATE.

          Without the written consent of the Required Banks and the Bank
effected thereby increase the amount of the Revolving Credit Commitment of such
Bank hereunder or without the written consent of all Banks extend the Expiration
Date;


                                       95
<Page>

          11.1.2. EXTENSION OF PAYMENT; REDUCTION OF PRINCIPAL INTEREST OR FEES;
MODIFICATION OF TERMS OF PAYMENT.

               Without the written consent of all Banks, 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 Bank, 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 Bank, or any other fee payable to
any Bank;

          11.1.3. RELEASE OF COLLATERAL OR GUARANTOR.

               Without the written consent of all Banks, release all or

          11.1.4. MISCELLANEOUS.

               Without the written consent of all Banks, amend Section 5.2 [Pro
Rata Treatment of Banks], 10.6 [Exculpatory Provisions, Etc.] or 10.13
[Equalization of Banks] or this Section 11.1, alter any provision regarding the
pro rata treatment of the Banks, change the definition of Required Banks, or
change any requirement providing for the Banks or the Required Banks to
authorize the taking of any action hereunder;

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

     11.3 REIMBURSEMENT AND INDEMNIFICATION OF BANKS BY THE BORROWER; TAXES.

     The Borrower agrees unconditionally upon demand to pay or reimburse to each
Bank (other than the Agent, as to which the Borrower's Obligations are set forth
in Section 10.5


                                       96
<Page>

[Reimbursement of Agent By Borrower, Etc.]) and to save such Bank harmless
against (i) liability for the payment of all reasonable out-of-pocket costs,
expenses and disbursements (including fees and expenses of counsel (including
allocated costs of staff counsel) for each Bank except with respect to (a) and
(b) below), incurred by such Bank (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, (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, and (e)
in connection with any Environmental Complaint threatened or asserted against
the Bank in any way relating to or arising out of this Agreement or any other
Loan Documents (including, without limitation, 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 in any workout or restructuring), 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 Bank, in its capacity as such,
in any way relating to or arising out of (y) this Agreement or any other Loan
Documents or any action taken or omitted by such Bank hereunder or thereunder
and (z) any Environmental Complaint in any way relating to or arising out of
this Agreement or any other Loan Documents or any action taken or omitted by
such Bank hereunder or thereunder, PROVIDED that the Borrower shall not be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements (A) if
the same results from such Bank's gross negligence or willful misconduct, 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 Banks will attempt to minimize the fees
and expenses of legal counsel for the Banks which are subject to reimbursement
by the Borrower hereunder by considering the usage of one law firm to represent
the Banks and the Agent if appropriate under the circumstances. The Borrower
agrees unconditionally to pay all stamp, document, transfer, recording or filing
taxes or fees and similar impositions now or hereafter determined by the Agent
or any Bank to be payable in connection with this Agreement or any other Loan
Document, and the Borrower agrees unconditionally to save the Agent and the
Banks harmless from and against any and all present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees or impositions.

     11.4 HOLIDAYS.

     Whenever 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 (except as provided in Section 4.2 [Interest Periods] with respect to
Interest Periods under the Euro-Rate


                                       97
<Page>

Option) and such 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, 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 Bank shall have the right from time to time, without notice
to the Borrower, to deem any branch, Subsidiary or Affiliate (which for the
purposes of this Section 11.5 shall mean any corporation or association which is
directly or indirectly controlled by or is under direct or indirect common
control with any corporation or association which directly or indirectly
controls such Bank) of such Bank to have made, maintained or funded any Loan to
which the Euro-Rate Option applies at any time, PROVIDED that immediately
following (on the assumption that a payment were then due from the Borrower to
such other office), and as a result of such change, the Borrower would not be
under any greater financial obligation pursuant to Section 5.5 [Additional
Compensation in Certain Circumstances] than it would have been in the absence of
such change. Notional funding offices may be selected by each Bank without
regard to such Bank's actual methods of making, maintaining or funding the Loans
or any sources of funding actually used by or available to such Bank.

          11.5.2. ACTUAL FUNDING.

               Each Bank shall have the right from time to time to make or
maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such
Bank to make or maintain such Loan subject to the last sentence of this Section
11.5.2. If any Bank causes a branch, Subsidiary or Affiliate to make or maintain
any part of the Loans hereunder, all terms and conditions of this Agreement
shall, except where the context clearly requires otherwise, be applicable to
such part of the Loans to the same extent as if such Loans were made or
maintained by such Bank, but in no event shall any Bank's use of such a branch,
Subsidiary or Affiliate to make or maintain any part of the Loans hereunder
cause such Bank or such branch, Subsidiary or Affiliate to incur any cost or
expenses payable by the Borrower hereunder or require the Borrower to pay any
other compensation to any Bank (including any expenses incurred or payable
pursuant to Section 5.5 [Additional Compensation in Certain Circumstances])
which would otherwise not be incurred.

     11.6 NOTICES; LENDING OFFICES.

of this Section 11.6 only, a "Notice") to be given to or made upon any party

of such Notice. SCHEDULE 1.1(B) lists the Lending Offices of each Bank. Each
Bank may change its Lending Office by written notice to the other parties
hereto.

     11.7 SEVERABILITY.

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

     11.11 SUCCESSORS AND ASSIGNS.

     (i) This Agreement shall be binding upon and shall inure to the benefit of
the Banks, the Agent, the Loan Parties and their respective successors and
assigns, except that none of the Loan Parties may assign or transfer any of its
rights and Obligations hereunder or any interest herein. Each Bank may, at its
own cost, make assignments of or sell participations in all or any part of its
Revolving Credit Commitments and the Loans made by it to one or more banks or
other entities, subject to the consent of the Borrower and the Agent with
respect to any assignee, such consent not to be unreasonably withheld or
delayed,


                                      100
<Page>

provided that (1) no consent of the Borrower shall be required (A) if an Event
of Default exists and is continuing, or (B) in the case of an assignment by a
Bank to an Affiliate of such Bank, and (2) any assignment by a Bank to a Person
other than an Affiliate of such Bank may not be made in amounts less than the
lesser of $5,000,000 or the amount of the assigning Bank's Commitment. In the
case of an assignment, upon receipt by the Agent of the Assignment and
Assumption Agreement, the assignee shall have, to the extent of such assignment
(unless otherwise provided therein), the same rights, benefits and obligations
as it would have if it had been a signatory Bank hereunder, the Commitments
shall be adjusted accordingly, and upon surrender of any Revolving Credit Note
subject to such assignment, the Borrower shall execute and deliver a new
Revolving Credit Note to the assignee in an amount equal to the amount of the
Revolving Credit Commitment assumed by it and a new Revolving Credit Note or
Term Note to the assigning Bank, in an amount equal to the Revolving Credit
Commitment retained by it hereunder. Any Bank which assigns any or all of its
Commitment or Loans to a Person other than an Affiliate of such Bank shall pay
to the Agent a service fee in the amount of $3,500 for each assignment. In the
case of a participation, the participant shall only have the rights specified in
Section 9.2.3 [Set-off] (the participant's rights against such Bank in respect
of such participation to be those set forth in the agreement executed by such
Bank in favor of the participant relating thereto and not to include any voting
rights except with respect to 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 Bank'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
Bank had not sold such participation.

     (ii) Any assignee or participant which is not incorporated under the Laws
of the United States of America or a state thereof shall deliver to the Borrower
and the Agent the form of certificate described in Section 11.17.1 [Tax
Withholding Clause] relating to federal income tax withholding. Each Bank may
furnish any publicly available information concerning any Loan Party or its
Subsidiaries and any other information concerning any Loan Party or its
Subsidiaries in the possession of such Bank from time to time to assignees and
participants (including prospective assignees or participants), PROVIDED that
such assignees and participants agree to be bound by the provisions of Section
11.12 [Confidentiality].

     (iii) Notwithstanding any other provision in this Agreement, any Bank may
at any time pledge or grant a security interest in all or any portion of its
rights under this Agreement, its Note and the other Loan Documents to any
Federal Reserve Bank in accordance with Regulation A of the FRB or U.S. Treasury
Regulation 31 CFR Section 203.14 without notice to or consent of the Borrower or
the Agent. No such pledge or grant of a security interest shall release the
transferor Bank of its obligations hereunder or under any other Loan Document.

     (iv) A bank which is to become a party to this Agreement pursuant to
Section 2.14 hereof or otherwise (each an "Additional Bank') shall execute and
deliver to Agent a Bank Joinder to this Agreement in substantially the form
attached hereto as EXHIBIT 1.1(B). Upon execution and delivery of a Bank
Joinder, such Additional Bank shall be a party hereto and a Bank under each of
the Loan Documents for all purposes, except


                                      101
<Page>

that such Additional Bank shall not participate in any Revolving Credit Loans to
which the Euro-Rate Option applies which are outstanding on the effective date
of such Bank Joinder. If Borrower should renew after the effective date of such
Bank Joinder the Euro-Rate Option with respect to Revolving Credit Loans
existing on such date, Borrower shall be deemed to repay the applicable
Revolving Credit Loans on the renewal date and then reborrow a similar amount on
such date so that the Additional Bank shall participate in such Revolving Credit
Loans after such renewal date. SCHEDULE 1.1(B) shall be automatically amended
and restated on the date of such Bank Joinder to revise the information
contained therein as appropriate to reflect the information on the attachment to
such Bank Joinder. Simultaneously with the execution and delivery of such Bank
Joinder, Borrower shall execute a Revolving Credit Note, and deliver it to such
Additional Bank together with originals of such other documents described in
Section 7.1 hereof as such Additional Bank may reasonably require.

     11.12 CONFIDENTIALITY.

          11.12.1. GENERAL.

               The Agent and the Banks each agree to keep confidential all
information obtained from any Loan Party or its Subsidiaries which is nonpublic
and confidential or proprietary in nature (including any information the
Borrower specifically designates as confidential), except as provided below, and
to use such information only in connection with their respective capacities
under this Agreement and for the purposes contemplated hereby. The Agent and the
Banks shall be permitted to disclose such information (i) to outside legal
counsel, accountants and other professional advisors who need to know such
information in connection with the administration and enforcement of this
Agreement, subject to agreement of such Persons to maintain the confidentiality,
(ii) to assignees and participants as contemplated by Section 11.11 [Successors
and Assigns], and prospective assignees and participants, (iii) to the extent
requested by any bank regulatory authority or, with notice to the Borrower, as
otherwise required by applicable Law or by any subpoena or similar legal
process, or in connection with any investigation or proceeding arising out of
the transactions contemplated by this Agreement, (iv) if it becomes publicly
available other than as a result of a breach of this Agreement or becomes
available from a source not known to be subject to confidentiality restrictions,
or (v) if the Borrower shall have consented to such disclosure. Notwithstanding
anything herein to the contrary, the information subject to this Section 11.12.1
shall not include, and the Agent and each Bank may disclose without limitation
of any kind, any information with respect to the "tax treatment" and "tax
structure" (in each case, within the meaning of Treasury Regulation Section
1.6011-4) of the transactions contemplated hereby and all materials of any kind
(including opinions or other tax analyses) that are provided to the Agent or
such Bank relating to such tax treatment and tax structure; PROVIDED that with
respect to any document or similar item that in either case contains information
concerning the tax treatment or tax structure of the transaction as well as
other information, this sentence shall only apply to such portions of the
document or similar item that relate to the tax treatment or tax structure of
the Loans, Letters of Credit and transactions contemplated hereby.

advisory, investment banking and other services may be offered or provided to
the Borrower or one or more of its Affiliates (in connection with this Agreement
or otherwise) by any Bank or by one or more Subsidiaries or Affiliates of such
Bank and each of the Loan Parties hereby authorizes each Bank to share any
information delivered to such Bank by such Loan Party and its Subsidiaries
pursuant to this Agreement, or in connection with the decision of such Bank to
enter into this Agreement, to any such Subsidiary or Affiliate of such Bank, it
being understood that any such Subsidiary or affiliate of any Bank receiving
such information shall be bound by the provisions of Section 11.12.1 as if it
were a Bank hereunder. Such Authorization shall survive the repayment of the
Loans and other Obligations and the termination of the Commitments.

     11.13 COUNTERPARTS.

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

     11.14 AGENT'S OR BANK'S CONSENT.

     Whenever the Agent's or any Bank's consent is required to be obtained under
this Agreement or any of the other Loan Documents as a condition to any action,
inaction, condition or event, the Agent and each Bank shall be authorized to
give or withhold such consent in its sole and absolute discretion and to
condition its consent upon the giving of additional collateral, the payment of
money or any other matter.

     11.15 EXCEPTIONS.

     The representations, warranties and covenants contained herein shall be
independent of each other, and no exception to any representation, warranty or
covenant shall be deemed to be an exception to any other representation,
warranty or covenant contained herein unless expressly provided, nor shall any
such exceptions be deemed to permit any action or omission that would be in
contravention of applicable Law.

     11.16 CONSENT TO FORUM; WAIVER OF JURY TRIAL.

     EACH LOAN PARTY HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE
JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY AND THE UNITED

          11.17.1. TAX WITHHOLDING CLAUSE.

               Each Bank or assignee or participant of a Bank that is not
incorporated under the Laws of the United States of America or a state thereof
(and, upon the written request of the Agent, each other Bank or assignee or
participant of a Bank) agrees that it will deliver to each of the Borrower and
the Agent two (2) duly completed appropriate valid Withholding Certificates (as
defined under SECTION 1.1441-1(c)(16) of the Income Tax Regulations (the
"Regulations")) certifying its status (i.e. U.S. or foreign person) and, if
appropriate, making a claim of reduced, or exemption from, U.S. withholding tax
on the basis of an income tax treaty or an exemption provided by the Internal
Revenue Code. The term "Withholding Certificate" means a Form W-9; a Form
W-8BEN; a Form W-8ECI; a Form W-8IMY and the related statements and
certifications as required under SECTION 1.1441-1(e)(2) and/or (3) of the
Regulations; a statement described in SECTION 1.871-14(c)(2)(v) of the
Regulations; or any other certificates under the Internal Revenue Code or
Regulations that certify or establish the status of a payee or beneficial owner
as a U.S. or foreign person. Each Bank, assignee or participant required to
deliver to the Borrower and the Agent a Withholding Certificate pursuant to the
preceding sentence shall deliver such valid Withholding Certificate as follows:
(A) each Bank which is a party hereto on the Closing Date shall deliver such
valid Withholding Certificate at least five (5) Business Days prior to the first
date on which any interest or fees are payable by the Borrower hereunder for the
account of such Bank; (B) each assignee or participant shall deliver such valid
Withholding Certificate at least five (5) Business Days before the effective
date of such assignment or participation (unless the Agent in its sole
discretion shall permit such assignee or participant to deliver such valid
Withholding Certificate less than five (5) Business Days before such date in
which case it shall be due on the date specified by the Agent). Each Bank,
assignee or participant which so delivers a valid Withholding Certificate
further undertakes to deliver to each of the Borrower and the Agent two (2)
additional copies of such Withholding Certificate (or a successor form) on or
before the date that such Withholding Certificate expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent
Withholding Certificate so delivered by it, and such amendments thereto or
extensions or renewals thereof as may be reasonably requested by the Borrower or
the Agent or as may be required by United States federal tax law.
Notwithstanding anything to the contrary, in the event that any Bank, assignee
or participant in any Bank fails to provide a Withholding Certificate on which
the Borrower and the Agent can reasonably rely, the Agent shall withhold U.S.
federal income taxes at the applicable rate prescribed under the Internal
Revenue Code and Regulations or any applicable treaty, taking into account any
Withholding Certificates on which it is entitled to rely, and shall have no
liability to any Bank for any amounts so withheld. In the event that a
Withholding Certificate is delivered to the Borrower or Agent by any Bank,
assignee or participant as to which the


                                      104
<Page>

Borrower or Agent, as the case may be, believe may not be valid, complete or
appropriate, the Borrower or Agent shall consult with such Bank, assignee, or
participant before declining to rely on such Withholding Certificate and shall
accept any reasonable attempt by the party delivering the Withholding
Certificate to correct any deficiencies in it. Notwithstanding the submission of
a Withholding Certificate claiming a reduced rate of or exemption from U.S.
withholding tax, the Agent shall be entitled to withhold United States federal
income taxes at the full applicable statutory withholding rate (30% as of the
date of this Agreement) if in its reasonable judgment it is required to do so
under the due diligence requirements imposed upon a withholding agent under
SECTION 1.1441-7(b) of the Regulations. Further, the Agent is indemnified under
SECTION 1.1461-1(e) of the Regulations against any claims and demands of any
Bank or assignee or participant of a Bank for the amount of any tax it deducts
and withholds in accordance with regulations under SECTION 1441 of the Internal
Revenue Code.

          11.17.2. USA PATRIOT ACT.

               Each Bank or assignee or participant of a Bank that is not
incorporated under the Laws of the United States of America or a state thereof
(and is not excepted from the certification requirement contained in Section 313
of the USA Patriot Act and the applicable regulations because it is both (i) an
affiliate of a depository institution or foreign bank that maintains a physical
presence in the United states or foreign county, and (ii) subject to supervision
by a banking authority regulating such affiliated depository institution or
foreign bank) shall deliver to the Agent the certification, or, if applicable,
recertification, certifying that such Bank is not a "shell" and certifying to
other matters as required by Section 313 of the USA Patriot Act and the
applicable regulations: (1) within 10 days after the Closing Date, and (2) as
such other times as are required under the USA Patriot Act.

     11.18 JOINDER OF GUARANTORS.

     Any Material Domestic Subsidiary of the Borrower which is required to join
this Agreement as a Guarantor pursuant to Section 8.2.9 [Subsidiaries,
Partnerships and Joint Ventures] shall execute and deliver to the Agent (i) a
Guarantor Joinder in substantially the form attached hereto as EXHIBIT 1.1(G)(1)
pursuant to which it shall join as a Guarantor each of the documents to which
the Guarantors are parties; (ii) documents in the forms described in Section 7.1
[First Loans] modified as appropriate to relate to such Material Domestic
Subsidiary, and (iii) documents necessary to grant and perfect Prior Security
Interests in all Pledged Collateral held by such Material Domestic Subsidiary.
The Loan Parties shall deliver such Guarantor Joinder and related documents to
the Agent within five (5) Business Days after the date of the filing of such
Material Domestic Subsidiary's articles of incorporation if the Material
Domestic Subsidiary is a corporation, the date of the filing of its certificate
of limited partnership if it is a limited partnership or the date of its
organization if it is an entity other than a limited partnership or corporation.

For purposes of determining the Applicable Margin, the Applicable Commitment Fee
Rate and the Applicable Letter of Credit Fee:

                  (A) The Applicable Margin, the Applicable Commitment Fee Rate,
and the Applicable Letter of Credit Fee shall be determined on the Closing Date
based on the Leverage Ratio computed on such date pursuant to that certificate
delivered pursuant to Section 7.1.11 [Certain Financial Conditions] hereof.

                  (B) The Applicable Commitment Fee Rate and the Applicable
Letter of Credit Fee shall be recomputed as of the end of each fiscal quarter
based on the Leverage Ratio as of such quarter end. The Applicable Margin shall
be recomputed as of the end of each fiscal quarter based on the Leverage Ratio
as of such quarter end. Any increase or decrease in the Applicable Margin, the
Applicable Commitment Fee Rate, or the Applicable Letter of Credit Fee computed
as of a quarter end shall be effective: (i) in the case of all Loans (other than
those described in the immediately following clause (ii) of this sentence), on
the date on which the Compliance Certificate and corresponding financial
statements evidencing such computation are due to be delivered under Section
8.3.3 [Certificate of the Borrower] (the "Reset Date"), and (ii) in the case of
each Borrowing Tranche of Loans made in an Optional Currency which Borrowing
Tranche is subject to an Interest Period the last day of which expires after the
current Reset Date, then as of the day following the last day of such Interest
Period; provided, however, that if the Borrower has failed to deliver, or caused
to be delivered, such Compliance Certificate and corresponding financial
statements on or before the date such delivery is due as required, as the case
may be, under Section 8.3.1 [Quarterly Financial Statements] or Section 8.3.2
[Annual Financial Statements] (the "Delivery Date"), then the Leverage Ratio
shall be deemed, solely for the purposes of determining the Applicable Margin,
the Applicable Commitment Fee Rate, and the Applicable Letter of Credit Fee, to
be greater than 2.0 to 1.0 from the Delivery Date until the


                               SCHEDULE 1.1(A) - 1
<Page>

Compliance Certificate and financial statements due for the fiscal quarter
subsequent to the fiscal quarter for which delivery did not timely occur by the
requisite Delivery Date are timely delivered as required, as the case may be,
under Section 8.3.2 [Quarterly Financial Statements] or Section 8.3.3 [Annual
Financial Statements].
