                          2. REVOLVING CREDIT FACILITY

     2.1     COMMITMENTS.

             Subject to the terms and conditions hereof and relying upon the
representations and warranties herein set forth, each Lender severally agrees to
make Loans to the Borrower at any time or from time to time on or after the date
hereof to the Expiration Date provided that after giving effect to such Loan (1)
the aggregate amount of Loans from such Lender shall not exceed such Lender's
Commitment minus such Lender's Ratable Share of the Letters of Credit
Outstanding, (2) the Facility Usage shall not exceed the Commitments, and (3)
the Total Usage shall not exceed the Total Usage Limitation. 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     NATURE OF LENDERS' OBLIGATIONS WITH RESPECT TO LOANS.

             Each Lender shall be obligated to participate in each request for
Loans pursuant to Section 2.4 [Loan Requests] in accordance with its Ratable
Share. The aggregate of each Lender's Loans outstanding hereunder to the
Borrower at any time shall never exceed its Commitment minus its Ratable Share
of the Letters of Credit Outstanding. The obligations of each Lender hereunder
are several. The failure of any Lender to perform its obligations hereunder
shall not affect the Obligations of the Borrower to any other party nor shall
any other

                                     - 30 -
<Page>

party be liable for the failure of such Lender to perform its obligations
hereunder or affect the obligation of any Lender to perform its obligations
hereunder. The Lenders shall have no obligation to make Loans hereunder on or
after the Expiration Date.

     2.3     COMMITMENT FEES.

             Accruing from the date hereof until the Expiration Date, the
Borrower agrees to pay to the Administrative Agent for the account of each
Lender, as consideration for such Lender's Commitment hereunder, a nonrefundable
commitment fee (the "Commitment Fee") equal to the Applicable Commitment Fee
Rate per annum (computed on the basis of a year of 365 or 366 days, as the case
may be, and actual days elapsed) on the average daily difference between the
amount of (i) such Lender's Commitment as the same may be constituted from time
to time and (ii) the sum of such Lender's Loans outstanding plus its Ratable
Share of Letters of Credit Outstanding (it is acknowledged the amount of any
Lender-Provided Letters of Credit Outstanding shall not be deducted from any
Lender's Commitment in computing such average daily difference). All Commitment
Fees shall be payable in arrears on the last day of each June, September,
December and March after the date hereof and on the Expiration Date or upon
acceleration of the Notes.

     2.4     LOAN REQUESTS.

             Except as otherwise provided herein, the Borrower may from time to
time prior to the Expiration Date request the Lenders to make Loans, or renew or
convert the Interest Rate Option applicable to existing Loans pursuant to
Section 3.2 [Interest Periods], by delivering to the Administrative Agent, not
later than 10:00 a.m., Pittsburgh time, (i) three (3) Business Days prior to the
proposed Borrowing Date with respect to the making of Loans to which the
Euro-Rate Option applies or the conversion to or the renewal of the Euro-Rate
Option for any Loans; and (ii) the Business Day of either the proposed Borrowing
Date with respect to the making of a 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 request therefor
substantially in the form of EXHIBIT 2.4 or a request by telephone immediately
confirmed in writing by letter, facsimile or telex in such form (each, a "Loan
Request"), it being understood that the Administrative Agent may rely on the
authority of any individual making such a telephonic request for deposit into an
account of the Borrower without the necessity of receipt of such written
confirmation. Each Loan Request shall be irrevocable and shall specify (i) the
proposed Borrowing Date; (ii) the aggregate amount of the proposed Loans
comprising each Borrowing Tranche, 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 which shall be 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; and (iv) 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     MAKING  LOANS.

             The Administrative Agent shall, promptly after receipt by it of a
Loan Request pursuant to Section 2.4 [Loan Requests], notify the Lenders of its
receipt of such Loan Request specifying: (i) the proposed Borrowing Date and the
time and method of disbursement of the Loans requested thereby; (ii) the amount
and type of each such Loan and the applicable Interest Period (if any); and
(iii) the apportionment among the Lenders of such Loans as determined by the
Administrative Agent in accordance with Section 2.2 [Nature of Lenders'
Obligations]. Each Lender shall remit the principal amount of each Loan to the
Administrative Agent such that the Administrative Agent is able to, and the
Administrative Agent shall, to the extent the Lenders have made funds available
to it for such purpose and subject to Section 6.2 [Each Additional Loan], fund
such 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 Lender fails to remit such funds to the
Administrative Agent in a timely manner, the Administrative Agent may elect in
its sole discretion to fund with its own funds the Loans of such Lender on such
Borrowing Date, and such Lender shall be subject to the repayment obligation in
Section 9.16 [Availability of Funds].

     2.6     NOTES.

             The Obligation of the Borrower to repay the aggregate unpaid
principal amount of the Loans made to it by each Lender, together with interest
thereon, shall be evidenced by a Note dated the Closing Date payable to the
order of such Lender in a face amount equal to the Commitment of such Lender.

     2.7     USE OF PROCEEDS.

     The proceeds of the Loans shall be used to repay the amounts outstanding
     under the Prior Credit Agreement, to provide for ongoing working capital
     needs and for general corporate purposes and in accordance with Section
     7.1.10 [Use of Proceeds].

     2.8     LETTER OF CREDIT SUBFACILITY.

                    2.8.1.  ISSUANCE OF LETTERS OF CREDIT.

                    Borrower may request the issuance of a letter of credit
(each such letter of credit, together with each letter of credit issued under
the Prior Credit Agreement, outstanding on the date hereof and referred to on
Schedule 2.8 (each of which shall be a Letter of Credit hereunder) is referred
to as a "Letter of Credit") on behalf of itself or another Loan Party by
delivering or having such other Loan Party deliver to the Administrative Agent a
completed application and agreement for letters of credit in such form as the
Administrative Agent may specify from time to time by no later than 11:00 a.m.,
Pittsburgh time, at least five (5) Business Days, or such shorter period as may
be agreed to by the Administrative Agent, in advance of the proposed date of
issuance. Each Letter of Credit shall be a Standby Letter of Credit or a
Commercial Letter of Credit. Subject to the terms and conditions hereof and in
reliance on the agreements of the other Lenders set forth in this Section 2.8,
the Administrative Agent or any of

                                     - 32 -
<Page>

the Administrative Agent's Affiliates will issue a Letter of Credit provided
that each Letter of Credit shall (A) have a maximum maturity of twelve (12)
months from the date of issuance provided, that, a Letter of Credit may provide
for the automatic renewal thereof subject to the right of the Administrative
Agent or applicant, prior to such automatic renewal, to terminate such Letter of
Credit on its original expiration date, and (B) in no event expire later than
five (5) Business Days prior to the Expiration Date and providing that in no
event shall (i) the Letters of Credit Outstanding exceed, at any one time,
$40,000,000 less the amount of the Lender-Provided Letters of Credit
Outstanding, (ii) the Facility Usage exceed, at any one time, the Commitments,
or (iii) the Total Usage exceed the Total Usage Limitation.

                    2.8.2.  LETTER OF CREDIT FEES.

                    The Borrower shall pay (i) to the Administrative Agent for
the ratable account of the Lenders a fee (the "Letter of Credit Fee") per annum
equal to the Applicable Margin applicable to Loans under the Euro-Rate Option,
and (ii) to the Administrative 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 Letters of Credit
Outstanding and shall be payable quarterly in arrears commencing with the last
day of each June, September, December and March following issuance of each
Letter of Credit and on the Expiration Date. The Borrower shall also pay to the
Administrative Agent for the Administrative Agent's sole account the
Administrative Agent's then in effect customary fees and administrative expenses
payable with respect to the Letters of Credit as the Administrative 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.

                    2.8.3.  DISBURSEMENTS, REIMBURSEMENT.

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

                    2.8.3.2  In the event of any request for a drawing under a
Letter of Credit by the beneficiary or transferee thereof, the Administrative
Agent will promptly notify the Borrower. Provided that it shall have received
such notice, the Borrower shall reimburse (such obligation to reimburse the
Administrative Agent shall sometimes be referred to as a "Reimbursement
Obligation") the Administrative Agent prior to 12:00 noon, Pittsburgh time on
each date that an amount is paid by the Administrative Agent under any Letter of
Credit (each such date, an "Drawing Date") in an amount equal to the amount so
paid by the Administrative Agent. In the event the Borrower fails to reimburse
the Administrative Agent for the full amount of any drawing under any Letter of
Credit by 12:00 noon, Pittsburgh time, on the Drawing Date, the Administrative
Agent will promptly notify each Lender thereof, and the Borrower shall be deemed
to have requested that Loans be made by the Lenders under the Base Rate Option
to be

                                     - 33 -
<Page>

disbursed on the Drawing Date under such Letter of Credit, subject to the amount
of the unutilized portion of the Commitment and subject to the conditions set
forth in Section 6.2 [Each Additional Loan] other than any notice requirements.
Any notice given by the Administrative Agent pursuant to this Section 2.8.3.2
may be oral if immediately confirmed in writing; provided that the lack of such
an immediate confirmation shall not affect the conclusiveness or binding effect
of such notice.

                    2.8.3.3  Each Lender shall upon any notice pursuant to
Section 2.8.3.2 make available to the Administrative Agent an amount in
immediately available funds equal to its Ratable Share of the amount of the
drawing, whereupon the participating Lenders shall (subject to Section 2.8.3.4)
each be deemed to have made a Loan under the Base Rate Option to the Borrower in
that amount. If any Lender so notified fails to make available to the
Administrative Agent for the account of the Administrative Agent the amount of
such Lender's Ratable Share of such amount by no later than 2:00 p.m.,
Pittsburgh time on the Drawing Date, then interest shall accrue on such Lender's
obligation to make such payment, from the Drawing Date to the date on which such
Lender makes such payment (i) at a rate per annum equal to the Federal Funds
Effective Rate during the first three days following the Drawing Date and (ii)
at a rate per annum equal to the rate applicable to Loans under the Base Rate
Option on and after the fourth day following the Drawing Date. The
Administrative Agent will promptly give notice of the occurrence of the Drawing
Date, but failure of the Administrative Agent to give any such notice on the
Drawing Date or in sufficient time to enable any Lender to effect such payment
on such date shall not relieve such Lender from its obligation under this
Section 2.8.3.3.

                    2.8.3.4  With respect to any unreimbursed drawing that is
not converted into Loans under the Base Rate Option to the Borrower in whole or
in part as contemplated by Section 2.8.3.2, because of the Borrower's failure to
satisfy the conditions set forth in Section 6.2 [Each Additional Loan] other
than any notice requirements or for any other reason, the Borrower shall be
deemed to have incurred from the Administrative Agent a borrowing (each a
"Letter of Credit Borrowing") in the amount of such drawing. Such Letter of
Credit Borrowing shall be due and payable on demand (together with interest) and
shall bear interest at the rate per annum applicable to the Loans under the Base
Rate Option. Each Lender's payment to the Administrative Agent pursuant to
Section 2.8.3.3 shall be deemed to be a payment in respect of its participation
in such Letter of Credit Borrowing and shall constitute a "Participation
Advance" from such Lender in satisfaction of its participation obligation under
this Section 2.8.3.

                    2.8.4.  REPAYMENT OF PARTICIPATION ADVANCES.

                    2.8.4.1  Upon (and only upon) receipt by the Administrative
Agent for its account of immediately available funds from the Borrower (i) in
reimbursement of any payment made by the Administrative Agent under the Letter
of Credit with respect to which any Lender has made a Participation Advance to
the Administrative Agent, or (ii) in payment of interest on such a payment made
by the Administrative Agent under such a Letter of Credit, the Administrative
Agent will pay to each Lender, in the same funds as those received by the
Administrative Agent, the amount of such Lender's Ratable Share of such funds,
except the

                                     - 34 -
<Page>

Administrative Agent shall retain the amount of the Ratable Share of such funds
of any Lender that did not make a Participation Advance in respect of such
payment by Administrative Agent.

                    2.8.4.2  If the Administrative 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 Administrative Agent pursuant to Section 2.8.4.1 in
reimbursement of a payment made under the Letter of Credit or interest or fee
thereon, each Lender shall, on demand of the Administrative Agent, forthwith
return to the Administrative Agent the amount of its Ratable Share of any
amounts so returned by the Administrative Agent plus interest thereon from the
date such demand is made to the date such amounts are returned by such Lender to
the Administrative Agent, at a rate per annum equal to the Federal Funds
Effective Rate in effect from time to time.

                    2.8.5.  DOCUMENTATION.

                    Each Loan Party agrees to be bound by the terms of the
Administrative Agent's application and agreement for letters of credit and the
Administrative Agent's written regulations and customary practices relating to
letters of credit. 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
Administrative 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.

                    2.8.6.  DETERMINATIONS TO HONOR DRAWING REQUESTS.

                    In determining whether to honor any request for drawing
under any Letter of Credit by the beneficiary thereof, the Administrative 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.

                    2.8.7.  NATURE OF PARTICIPATION AND REIMBURSEMENT
OBLIGATIONS.

                    Each Lender's obligation in accordance with this Agreement
to make the Loans or Participation Advances, as contemplated by Section 2.8.3,
as a result of a drawing under a Letter of Credit, and the Obligations of the
Borrower to reimburse the Administrative 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 2.8 under all
circumstances, including the following circumstances:

                    (i)     any set-off, counterclaim, recoupment, defense or
other right which such Lender may have against the Administrative Agent or any

<Page>

                    (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 [Commitments], 2.4 [Loan Requests], 2.5 [Making Loans] or
6.2 [Each Additional Loan] or as otherwise set forth in this Agreement for the
making of a Loan, it being acknowledged that such conditions are not required
for the making of a Letter of Credit Borrowing and the obligation of the Lenders
to make Participation Advances under Section 2.8.3;

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

                    (iv)    any claim of breach of warranty that might be made
by any Loan Party or any Lender 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 Lender 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 Administrative Agent or its Affiliates or any
Lender or any other Person or, whether in connection with this Agreement, the
transactions contemplated herein or any unrelated transaction (including any
underlying transaction between 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
Administrative Agent or any of the Administrative Agent's Affiliates has been
notified thereof;

                    (vi)    payment by the Administrative 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

                    (viii)  any failure by the Administrative Agent or any of
Administrative Agent's Affiliates to issue any Letter of Credit in the form
requested by any Loan Party, unless the Administrative Agent has received
written notice from such Loan Party of such failure within three Business Days
after the Administrative 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;

                    (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.

                    2.8.8.  INDEMNITY.

                    In addition to amounts payable as provided in Section 9.5
[Reimbursement of Administrative Agent by Borrower, Etc.], the Borrower hereby
agrees to protect, indemnify, pay and save harmless the Administrative Agent and
any of Administrative 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 Administrative Agent or any of Administrative 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 or willful misconduct of the Administrative Agent as determined by a
final judgment of a court of competent jurisdiction or (B) the wrongful dishonor
by the Administrative Agent or any of Administrative 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").

                    2.8.9.  LIABILITY FOR ACTS AND OMISSIONS.

                    As between any Loan Party and the Administrative Agent, or
the Administrative 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 Administrative 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 Administrative Agent or the
Administrative 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

                                     - 37 -
<Page>

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 consequences arising
from causes beyond the control of the Administrative Agent or the Administrative
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
Administrative Agent's or the Administrative Agent's Affiliates rights or powers
hereunder. Nothing in the preceding sentence shall relieve the Administrative
Agent from liability for the Administrative Agent's 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 Administrative Agent or
the Administrative 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
Administrative Agent and each of its Affiliates (i) may rely on any oral or
other communication believed in good faith by the Administrative 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 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 Administrative
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, 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
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
Administrative Agent or the Administrative 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

                                     - 38 -
<Page>

put the Administrative Agent or the Administrative Agent's Affiliates under any
resulting liability to the Borrower or any Lender.

     2.9     REDUCTION OF COMMITMENTS.

                    The Borrower shall have the right at any time and from time
to time upon five (5) Business Days' prior written notice to the Administrative
Agent to permanently reduce, in whole multiples of $5,000,000 and in integral
multiples of $1,000,000 of principal, or terminate the Commitments without
penalty or premium, except as hereinafter set forth, provided that any such
reduction or termination shall be accompanied by (a) the payment in full of any
Commitment Fee then accrued on the amount of such reduction or termination and
(b) prepayment of the Notes, together with the full amount of interest accrued
on the principal sum to be prepaid (and all indemnity due under Section 4.5.2(i)
hereof), to the extent that the Facility Usage exceeds the Commitments as so
reduced or terminated, or the Total Usage exceeds the Total Usage Limitation.
From the effective date of any such reduction or termination the obligations of
Borrower to pay the Commitment Fee pursuant to Section 2.3 shall correspondingly
be reduced or cease.

                                3. INTEREST RATES

     3.1     INTEREST RATE OPTIONS.

             The Borrower shall pay interest in respect of the outstanding
unpaid principal amount of the Loans as selected by it from the Base Rate Option
or Euro-Rate Option set forth below applicable to the 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 Loans comprising different Borrowing Tranches and may
convert to or renew one or more Interest Rate Options with respect to all or any
portion of the Loans comprising any Borrowing Tranche, PROVIDED that there shall
not be at any one time outstanding more than ten (10) Borrowing Tranches in the
aggregate among all of the Loans. If at any time the designated rate applicable
to any Loan made by any Lender exceeds such Lender's highest lawful rate, the
rate of interest on such Lender's Loan shall be limited to such Lender's highest
lawful rate.

                    3.1.1.  OPTIONS.

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

                         (i)    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

                                     - 39 -
<Page>

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

                    3.1.2.  RATE QUOTATIONS.

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

     3.2     INTEREST PERIODS.

             At any time when the Borrower shall select, convert to or renew a
Euro-Rate Option, the Borrower shall notify the Administrative Agent thereof at
least three (3) Business Days prior to the effective date of such Euro-Rate
Option by delivering a Loan Request. The notice shall specify an Interest Period
during which such Interest Rate Option shall apply. Notwithstanding the
preceding sentence, the following provisions shall apply to any selection of,
renewal of, or conversion to a Euro-Rate Option:

                    3.2.1.  AMOUNT OF BORROWING TRANCHE.

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

                    3.2.2.  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.

     3.3     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:

                    3.3.1. LETTER OF CREDIT FEES, INTEREST RATE.

                    the Letter of Credit Fees and the rate of interest for each
Loan otherwise applicable pursuant to Section 2.8.2 [Letter of Credit Fees] or
Section 3.1 [Interest Rate Options], respectively, shall be increased by 2.0%
per annum; and

                    3.3.2.  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 Base Rate Option

                                     - 40 -
<Page>

plus an additional 2% per annum from the time such Obligation becomes due and
payable and until it is paid in full.

                    3.3.3.  ACKNOWLEDGMENT.

                    The Borrower acknowledges that the increase in rates
referred to in this Section 3.3 reflects, among other things, the fact that such
Loans or other amounts have become a substantially greater risk given their
default status and that the Lenders are entitled to additional compensation for
such risk; and all such interest shall be payable by Borrower upon demand by
Administrative Agent.

     3.4     EURO-RATE UNASCERTAINABLE; ILLEGALITY; INCREASED COSTS; DEPOSITS
             NOT AVAILABLE.

                    3.4.1.  UNASCERTAINABLE.

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

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

                    (ii)    a contingency has occurred which materially and
adversely affects the London interbank eurodollar market relating to the
Euro-Rate, the Administrative Agent shall have the rights specified in Section
3.4.3.

                    3.4.2.  ILLEGALITY; INCREASED COSTS; DEPOSITS NOT AVAILABLE.

                    If at any time any Lender shall have determined that:

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

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

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

then the Administrative Agent shall have the rights specified in Section 3.4.3.

                                     - 41 -
<Page>

                    3.4.3.  ADMINISTRATIVE AGENT'S AND LENDER'S RIGHTS.

                    In the case of any event specified in Section 3.4.1 above,
the Administrative Agent shall promptly so notify the Lenders and the Borrower
thereof, and in the case of an event specified in Section 3.4.2 above, such
Lender shall promptly so notify the Administrative Agent and endorse a
certificate to such notice as to the specific circumstances of such notice, and
the Administrative Agent shall promptly send copies of such notice and
certificate to the other Lenders and the Borrower. Upon such date as shall be
specified in such notice (which shall not be earlier than the date such notice
is given), the obligation of (A) the Lenders, in the case of such notice given
by the Administrative Agent, or (B) such Lender, in the case of such notice
given by such Lender, to allow the Borrower to select, convert to or renew a
Euro-Rate Option shall be suspended until the Administrative Agent shall have
later notified the Borrower, or such Lender shall have later notified the
Administrative Agent, of the Administrative Agent's or such Lender's, as the
case may be, determination that the circumstances giving rise to such previous
determination no longer exist. If at any time the Administrative Agent makes a
determination under Section 3.4.1 and the Borrower has previously notified the
Administrative Agent of its selection of, conversion to or renewal of a
Euro-Rate Option and such Interest Rate Option has not yet gone into effect,
such notification shall be deemed to provide for selection of, conversion to or
renewal of the Base Rate Option otherwise available with respect to such Loans.
If any Lender notifies the Administrative Agent of a determination under
Section 3.4.2, the Borrower shall, subject to the Borrower's indemnification
Obligations under Section 4.5.2 [Indemnity], as to any Loan of the Lender to
which a Euro-Rate Option applies, on the date specified in such notice either
convert such Loan to the Base Rate Option otherwise available with respect to
such Loan or prepay such Loan in accordance with Section 4.4 [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.

     3.5     SELECTION OF INTEREST RATE OPTIONS.

             If the Borrower fails to select a new Interest Period to apply to
any Borrowing Tranche of Loans under the Euro-Rate Option at the expiration of
an existing Interest Period applicable to such Borrowing Tranche in accordance
with the provisions of Section 3.2 [Interest Periods], the Borrower shall be
deemed to have converted such Borrowing Tranche to the Base Rate Option,
commencing upon the last day of the existing Interest Period.

                                   4. PAYMENTS

     4.1     PAYMENTS.

             All payments and prepayments to be made in respect of principal,
interest, Commitment Fees, Letter of Credit Fees, Administrative Agent's Fee or
other fees or amounts due from the Borrower hereunder shall be payable prior to
12:00 p.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

                                     - 42 -
<Page>

of any nature, and an action therefor shall immediately accrue. Such payments
shall be made to the Administrative Agent at the Principal Office for the
ratable accounts of the Lenders with respect to the Loans in U.S. Dollars and in
immediately available funds, and the Administrative Agent shall promptly
distribute such amounts to the Lenders in immediately available funds, PROVIDED
that in the event payments are received by 12:00 p.m., Pittsburgh time, by the
Administrative Agent with respect to the Loans and such payments are not
distributed to the Lenders on the same day received by the Administrative Agent,
the Administrative Agent shall pay the Lenders the Federal Funds Effective Rate
with respect to the amount of such payments for each day held by the
Administrative Agent and not distributed to the Lenders. The Administrative
Agent's and each Lender's statement of account, ledger or other relevant record
shall, in the absence of manifest error, be conclusive as the statement of the
amount of principal of and interest on the Loans and other amounts owing under
this Agreement and shall be deemed an "account stated."

     4.2     PRO RATA TREATMENT OF LENDERS.

             Each borrowing shall be allocated to each Lender according to its
Ratable Share, and each selection of, conversion to or renewal of any Interest
Rate Option and each payment or prepayment by the Borrower with respect to
principal, interest, Commitment Fees, Letter of Credit Fees, or other fees
(except for the Administrative Agent's Fee) or amounts due from the Borrower
hereunder to the Lenders with respect to the Loans, shall (except as provided in
Section 3.4.3 [Administrative Agent's and Lender's Rights] in the case of an
event specified in Section 3.4 [Euro-Rate Unascertainable; Etc.], 4.4.2
[Replacement of a Lender] or 4.5 [Additional Compensation in Certain
Circumstances]) be made in proportion to the applicable Loans outstanding from
each Lender and, if no such Loans are then outstanding, in proportion to the
Ratable Share of each Lender.

     4.3     INTEREST PAYMENT DATES.

             Interest on Loans to which the Base Rate Option applies shall be
due and payable in arrears on the last day of each June, September, December and
March after the date hereof and on the Expiration Date or upon acceleration of
the Notes. Interest on Loans to which the Euro-Rate Option applies shall be due
and payable 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 the principal amount of each Loan or other monetary
Obligation shall be due and payable on demand after such principal amount or
other monetary Obligation becomes due and payable (whether on the stated
maturity date, upon acceleration or otherwise).

     4.4     VOLUNTARY PREPAYMENTS.

                    4.4.1.  RIGHT TO PREPAY.

                    The Borrower shall have the right at its option from time to
time to prepay the Loans in whole or part without premium or penalty (except as
provided in Section 4.4.2 below or in Section 4.5 [Additional Compensation in
Certain Circumstances]):

                                     - 43 -
<Page>

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

                    (ii)    on the last day of the applicable Interest Period
with respect to Loans to which a Euro-Rate Option applies (provided that the
Borrower may repay such a Loan on a day other than the last day of the
applicable Interest Period if the Borrower indemnifies the Banks pursuant to
Section 4.5.2 [Indemnity],

                    (iii)   on the date specified in a notice by any Lender
pursuant to Section 3.4 [Euro-Rate Unascertainable, Etc.] with respect to any
Loan to which a Euro-Rate Option applies.

                    Whenever the Borrower desires to prepay any part of the
Loans, it shall provide a prepayment notice to the Administrative Agent by 2:00
p.m. at least one (1) Business Day prior to the date of prepayment of 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 Loans; and

                  (z)   the total principal amount of such prepayment, which
             shall not be less than $500,000.

                    All prepayment notices shall be irrevocable. The principal
amount of the Loans for which a prepayment notice is given, together with
interest on such principal amount except with respect to Loans to which the Base
Rate Option applies, shall be due and payable on the date specified in such
prepayment notice as the date on which the proposed prepayment is to be made.
Except as provided in Section 3.4.3 [Administrative Agent's and Lender's
rights], if the Borrower prepays a Loan but fails to specify the applicable
Borrowing Tranche which the Borrower is prepaying, the prepayment shall be
applied first to Loans to which the Base Rate Option applies, then to Loans to
which the Euro-Rate Option applies. Any prepayment hereunder shall be subject to
the Borrower's Obligation to indemnify the Lenders under Section 4.5.2
[Indemnity].

                    4.4.2.  REPLACEMENT OF A LENDER.

                    In the event any Lender (i) gives notice under Section 3.4
[Euro-Rate Unascertainable, Etc.] or Section 4.5.1 [Increased Costs, Etc.], (ii)
does not fund Loans because the making of such Loans would contravene any Law
applicable to such Lender, 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 Administrative
Agent, which shall not be unreasonably withheld or delayed, to prepay the Loans
of such Lender in whole, together with all interest accrued thereon, and
terminate such Lender's Commitment within ninety (90) days after (x) receipt of
such Lender's notice under Section 3.4 [Euro-Rate

                                     - 44 -
<Page>

Unascertainable, Etc.] or 4.5.1 [Increased Costs, Etc.], (y) the date such
Lender has failed to fund Loans because the making of such Loans would
contravene Law applicable to such Lender, or (z) the date such Lender became
subject to the control of an Official Body, as applicable; PROVIDED that the
Borrower shall also pay to such Lender at the time of such prepayment any
amounts required under Section 4.5 [Additional Compensation in Certain
Circumstances] and any accrued interest due on such amount and any related fees;
PROVIDED, however, that the Commitment of such Lender shall be provided by one
or more of the remaining Lenders or a replacement bank acceptable to the
Administrative Agent; PROVIDED, further, the remaining Lenders shall have no
obligation hereunder to increase their Commitments. Notwithstanding the
foregoing, the Administrative Agent may only be replaced subject to the
requirements of Section 9.14 [Successor Administrative Agent] and PROVIDED that
all Letters of Credit have expired or been terminated or replaced.

                    4.4.3.  CHANGE OF LENDING OFFICE.

                    Each Lender agrees that upon the occurrence of any event
giving rise to increased costs or other special payments under Section 3.4.2
[Illegality, Etc.] or 4.5.1 [Increased Costs, Etc.] with respect to such Lender,
it will if requested by the Borrower, use reasonable efforts (subject to overall
policy considerations of such Lender) to designate another lending office for
any Loans or Letters of Credit affected by such event, PROVIDED that such
designation is made on such terms that such Lender and its lending office suffer
no economic, legal or regulatory disadvantage, with the object of avoiding the
consequence of the event giving rise to the operation of such Section. Nothing
in this Section 4.4.3 shall affect or postpone any of the Obligations of the
Borrower or any other Loan Party or the rights of the Administrative Agent or
any Lender provided in this Agreement.

     4.5     ADDITIONAL COMPENSATION IN CERTAIN CIRCUMSTANCES.

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

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

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

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

                                     - 45 -
<Page>

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

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

                    4.5.2.  INDEMNITY.

                    In addition to the compensation required by Section 4.5.1
[Increased Costs, Etc.], the Borrower shall indemnify each Lender 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 Lender to fund or
maintain Loans subject to a Euro-Rate Option) which such Lender sustains or
incurs as a consequence of any

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

                    (ii)    attempt by the Borrower to revoke (expressly, by
later inconsistent notices or otherwise) in whole or part any Loan Requests
under Section 2.4 [Loan Requests] or Section 3.2 [Interest Periods] or notice
relating to prepayments under Section 4.4 [Voluntary Prepayments], or

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

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

                                     - 46 -
<Page>

Lender for such loss or expense. Such notice shall set forth in reasonable
detail the basis for such determination. Such amount shall be due and payable by
the Borrower to such Lender ten (10) Business Days after such notice is given.

                        5. REPRESENTATIONS AND WARRANTIES

     5.1     REPRESENTATIONS AND WARRANTIES.

             The Loan Parties, jointly and severally, represent and warrant to
the Administrative Agent and each of the Lenders as follows:

                    5.1.1.  ORGANIZATION AND QUALIFICATION.

                    Each Loan Party is a corporation, partnership or limited
liability company duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization except (in the case of each Loan
Party other than the Borrower) where the failure to do so would not cause a
Material Adverse Change. Each Loan Party has the lawful power to own or lease
its properties and to engage in the business it presently conducts or proposes
to conduct except where failure to do so would not cause a Material Adverse
Change. Each Loan Party is duly licensed or qualified and in good standing in
each jurisdiction where the property owned or leased by it or the nature of the
business transacted by it or both makes such licensing or qualification
necessary except where failure to do so would not cause a Material Adverse
Change and SCHEDULE 5.1.1 shall list such jurisdictions as of the Closing Date
and each SCHEDULE UPDATE DATE.

                    5.1.2.  CAPITALIZATION AND OWNERSHIP.

                    The authorized, issued and outstanding capital stock of the
Borrower as of March 31, 2002 was as set forth in the Interim Statements.

                    5.1.3.  SUBSIDIARIES.

                    As of the Closing Date and as of each of the Schedule Update

Subsidiaries (other than the Excluded Subsidiaries and Foreign Subsidiaries),
its jurisdiction of organization, its authorized capital stock, the issued and
outstanding shares of capital stock (referred to herein as the "Subsidiary
Shares") and the owners thereof if it is a corporation, its outstanding
partnership interests (the "Partnership Interests") if it is a partnership and
its outstanding limited liability company interests, interests assigned to
managers thereof and the voting rights associated therewith (the "LLC
Interests") if it is a limited liability company and (2) to the Borrower's
knowledge, shall state the name and jurisdiction of organization of each
Excluded Subsidiary. The Borrower and each Subsidiary (other than the Excluded
Subsidiaries) of the Borrower has good and marketable title to all of the
Subsidiary Shares, Partnership Interests and LLC Interests, as the case may be,
it purports to own, free and clear in each case of any Lien other than Permitted
Liens. All Subsidiary Shares, Partnership Interests and LLC Interests have been

                                     - 47 -
<Page>

validly issued, and all Subsidiary Shares are fully paid and nonassessable. All
capital contributions and other consideration required to be made or paid in
connection with the issuance of the Partnership Interests and LLC Interests have
been made or paid, as the case may be. As of the Closing Date and each of the
Schedule Update Dates, there are no options, warrants or other rights
outstanding to purchase any such Subsidiary Shares, Partnership Interests or LLC
Interests except as indicated on SCHEDULE 5.1.3 or as permitted by Sections
7.2.7 and 7.2.8.

                    5.1.4.  POWER AND AUTHORITY.

                    Each Loan Party has full power to enter into, execute,
deliver and carry out this Agreement and the other Loan Documents to which it is
a party, to incur the Indebtedness contemplated by the Loan Documents and to
perform its Obligations under the Loan Documents to which it is a party, and all
such actions have been duly authorized by all necessary proceedings on its part.

                    5.1.5.  VALIDITY AND BINDING EFFECT.

                    This Agreement has been duly and validly executed and
delivered by each Loan Party, and each other Loan Document which any Loan Party
is required to execute and deliver on or after the date hereof will have been
duly executed and delivered by such Loan Party on the required date of delivery
of such Loan Document. This Agreement and each other Loan Document constitutes,
or will constitute, legal, valid and binding obligations of each Loan Party
which is or will be a party thereto on and after its date of delivery thereof,
enforceable against such Loan Party in accordance with its terms, except to the
extent that enforceability of any of such Loan Document may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforceability of creditors' rights generally or limiting the
right of specific performance.

                    5.1.6.  NO CONFLICT.

                    Neither the execution and delivery of this Agreement or the
other Loan Documents by any Loan Party nor the consummation of the transactions
herein or therein contemplated or compliance with the terms and provisions
hereof or thereof by any of them will conflict with, constitute a default under
or result in any breach of (i) the terms and conditions of the certificate of
incorporation, bylaws, certificate of limited partnership, partnership
agreement, certificate of formation, limited liability company agreement or
other organizational documents of any Loan Party or (ii) any Law or any material

                    5.1.7.  LITIGATION.

                    There are no actions, suits, proceedings or investigations
pending or, to the knowledge of any Loan Party, threatened in writing against
such Loan Party or any Subsidiary of such Loan Party at law or equity before any
Official Body which individually or in the aggregate may result in any Material
Adverse Change. None of the Loan Parties or any Subsidiaries of any Loan Party

Body which may result in any Material Adverse Change.

                    5.1.8.  TITLE TO PROPERTIES.

leasehold interest in all material properties, assets and other rights which it
purports to own or lease or which are reflected as owned or leased on its books
and records, free and clear of all Liens and encumbrances except Permitted
Liens, and subject to the terms and conditions of the applicable leases. All
leases of material property are in full force and effect without the necessity

transactions contemplated hereby.

                    5.1.9.  FINANCIAL STATEMENTS.

                    (i)     HISTORICAL STATEMENTS. The Borrower has delivered to
the Administrative Agent copies of its audited consolidated year-end financial
statements for and as of the end of the fiscal year ended June 30, 2001 (the
"Annual Statements"). In addition, the Borrower has delivered to the
Administrative Agent copies of its unaudited consolidated interim financial
statements for the nine months ended March 31, 2002, and as of the end of the
fiscal quarter ended March 31, 2002 (the "Interim Statements") (the Annual and
Interim Statements being collectively referred to as the "Historical
Statements"). The Historical Statements were compiled from the books and records
maintained by the Borrower's management, are correct and complete in all
material respects and fairly present the consolidated financial condition of the
Borrower and its Subsidiaries as of their dates and the results of operations
for the fiscal periods then ended and have been prepared in accordance with GAAP
consistently applied, subject (in the case of the Interim Statements) to normal
year-end audit adjustments.

                    (ii)    FINANCIAL PROJECTIONS. The Borrower has delivered to
the Administrative Agent financial projections of the Borrower and its
Subsidiaries for the four quarterly periods ending September 30 and December 31,
2002 and March 31 and June 30, 2003 and the twelve-month periods ending June 30,
2004, 2005 and 2006 which are derived from various assumptions of the Borrower's
management (the "Financial Projections"). At the time made, the Financial
Projections were within the range of reasonably possible results in light of the
history of the business, present and foreseeable conditions and the intentions
of the Borrower's management.

                    (iii)   ACCURACY OF FINANCIAL STATEMENTS. Neither the
Borrower nor any Subsidiary of the Borrower had any material liabilities,
contingent or otherwise, or forward or long-term commitments that in accordance
with GAAP, were required to be included on a

                                     - 49 -
<Page>

balance sheet or in the notes thereto which were not disclosed in the Historical
Statements or in the notes thereto, and except as disclosed therein there are no
unrealized or anticipated losses from any commitments of the Borrower or any
Subsidiary of the Borrower which may cause a Material Adverse Change. Since June
30, 2001, no Material Adverse Change has occurred.

                    5.1.10. USE OF PROCEEDS; MARGIN STOCK; SECTION 20

                    5.1.10.1 GENERAL.

Party engages or intends to engage principally, or as one of its important
activities, in the business of extending credit for the purpose, immediately,
incidentally or ultimately, of purchasing or carrying margin stock (within the
meaning of Regulation U). No part of the proceeds of any Loan has been or will
be used, immediately, incidentally or ultimately, to purchase or carry any
margin stock or to extend credit to others for the purpose of purchasing or
carrying any margin stock or to refund Indebtedness originally incurred for such
purpose, or for any purpose which entails a violation of or which is
inconsistent with the provisions of the regulations of the Board of Governors of
the Federal Reserve System. None of the Loan Parties or any Subsidiary of any
Loan Party holds or intends to hold margin stock in such amounts that more than
25% of the reasonable value of the assets of any Loan Party or Subsidiary of any
Loan Party are or will be represented by margin stock.

                    5.1.10.3 SECTION 20 SUBSIDIARIES.

                    The Loan Parties do not intend to use and shall not use any

Securities being underwritten by a Section 20 Subsidiary.

or Subsidiary of any Loan Party which has not been set forth in this Agreement
or in the certificates, statements, agreements or other documents

payment of all taxes, fees, assessments and other governmental charges which
have or may become due pursuant to said returns or to assessments received,
except to the extent that such taxes, fees, assessments and other charges are

partnership agreement, certificate of formation, limited liability company
agreement or other organizational documents or (ii) any material agreement or
instrument to which it is a party or by which it or any of its properties may be
subject or bound where such violation would constitute a Material Adverse
Change.

                    5.1.15. PATENTS, TRADEMARKS, COPYRIGHTS, LICENSES, ETC.

                    Each Loan Party and each Subsidiary of each Loan Party owns

member of the ERISA Group (i) have fulfilled in all material respects their
obligations under the minimum funding standards of ERISA, (ii) have not incurred

penalty for failure to fulfill the minimum funding requirements of ERISA.

                    (ii)    To the best of the Borrower's knowledge, each
Multiemployer Plan and Multiple Employer Plan is able to pay benefits for which
an ERISA Group Member would have a material liability thereunder when due.

                    (iii)   Neither the Borrower nor any other member of the
ERISA Group has instituted or intends to institute proceedings to terminate any
Plan for which there would be a material liability for the Borrower or a member
of the ERISA Group.

                    (iv)    No event requiring notice to the PBGC under
Section 302(f)(4)(A) of ERISA has occurred or is reasonably expected to occur
with respect to any Plan, and no amendment with respect to which security is
required under Section 307 of ERISA has been made or is reasonably expected to
be made to any Plan which would constitute a Material Adverse Change.

                    (v)     The aggregate actuarial present value of all benefit
liabilities (whether or not vested) under each Plan, determined on a plan
termination basis, as disclosed in, and as of the date of, the most recent
actuarial report for such Plan, does not exceed the aggregate fair market value
of the assets of such Plan by an amount which would be a material liability for
the Borrower.

                    (vi)    Neither the Borrower nor any other member of the
ERISA Group has incurred or reasonably expects to incur any material withdrawal

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 any amount

Agent, shall be applied as follows:

                    (i)     first, to reimburse the Administrative Agent and the

including reasonable attorneys' and paralegals' fees and legal expenses,
incurred by the Administrative Agent or the Lenders in connection with realizing
on the Collateral or collection of any Obligations of any of the Loan Parties
under any of the Loan Documents, including advances made by the Lenders or their

sale or other realization on, any of the Collateral;

                    (ii)    second, to the repayment (or cash collateralization)
of all Obligations then due and unpaid of the Loan Parties to the Lenders
incurred under this Agreement or any of the other Loan Documents or a
Lender-Provided Letter of Credit Facility (including undrawn letters of credit)
or to any Lender or any Affiliate of a Lender which has entered into a
Lender-Provided Hedge, whether of principal, interest, fees, expenses or
otherwise, in such manner as the Administrative Agent may determine in its
discretion; and

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

                    8.2.5.2 COLLATERAL SHARING.

                    All Liens granted under the Security Agreement, the Patent
Trademark and Copyright Security Agreement, the Pledge Agreement and any other

PASSU basis (i) the Obligations in

                                     - 86 -
<Page>

favor of the Administrative Agent and the Lenders hereunder and (ii) the
Obligations incurred by any of the Loan Parties in favor of any Lender or
Affiliate of such Lender which provides a Lender-Provided Hedge (the "HEDGE
PROVIDER"). The Administrative Agent under the Collateral Documents shall be
deemed to serve as the collateral agent (the "COLLATERAL ADMINISTRATIVE AGENT")
for the Hedge Provider and the Lenders hereunder, provided that the Collateral
Administrative Agent shall comply with the instructions and directions of the
Administrative Agent (or the Lenders under this Agreement to the extent that
this Agreement or any other Loan Documents empowers the Lenders to direct the
Administrative Agent), as to all matters relating to the Collateral, including
the maintenance and disposition thereof. No Hedge Provider (except in its
capacity as a Lender hereunder) shall be entitled or have the power to direct or
instruct the Collateral Administrative Agent on any such matters or to control
or direct in any manner the maintenance or disposition of the Collateral.

                    8.2.6.  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 Administrative Agent
shall have all of the rights and remedies of a secured party under the Uniform
Commercial Code or other applicable Law, all of which rights and remedies shall
be cumulative and non-exclusive, to the extent permitted by Law. The
Administrative Agent may, and upon the request of the Required Lenders shall,
exercise all post-default rights granted to the Administrative Agent and the
Lenders under the Loan Documents or applicable Law.

     8.3     NOTICE OF SALE.

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

action, shall constitute commercially reasonable and fair notice thereof to the
Borrower.

                           9. THE ADMINISTRATIVE AGENT

     9.1     APPOINTMENT.

             Each Lender hereby irrevocably designates, appoints and authorizes
PNC Bank to act as Administrative Agent for such Lender under this Agreement and
to execute and deliver or accept on behalf of each of the Lenders the other Loan
Documents. Each Lender hereby irrevocably authorizes, and each holder of any
Note by the acceptance of a Note shall be deemed irrevocably to authorize, the
Administrative 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
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. PNC Bank agrees to act as the Administrative
Agent on behalf of the Lenders to the extent provided in this Agreement.

                                     - 87 -
<Page>

     9.2     DELEGATION OF DUTIES.

             The Administrative 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 Administrative Agent) and, subject to Sections
9.5 [Reimbursement of Administrative Agent by Borrower, Etc.] and 9.6, shall be
entitled to engage and pay for the advice or services of any attorneys,
accountants or other experts concerning all matters pertaining to its duties
hereunder and to rely upon any advice so obtained.

     9.3     NATURE OF DUTIES; INDEPENDENT CREDIT INVESTIGATION.

             The Administrative 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 Administrative Agent
shall be mechanical and administrative in nature; the Administrative Agent shall
not have by reason of this Agreement a fiduciary or trust relationship in
respect of any Lender; and nothing in this Agreement, expressed or implied, is
intended to or shall be so construed as to impose upon the Administrative Agent
any obligations in 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 Administrative Agent is not
intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable Law. Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties. Each
Lender expressly acknowledges (i) that the Administrative Agent has not made any
representations or warranties to it and that no act by the Administrative 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
Administrative Agent to any Lender; (ii) that it has made and will continue to
make, without reliance upon the Administrative 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 Administrative Agent shall have no
duty or responsibility, either initially or on a continuing basis, to provide
any Lender with any credit or other information with respect thereto, whether
coming into its possession before the making of any Loan or at any time or times
thereafter.

     9.4     ACTIONS IN DISCRETION OF ADMINISTRATIVE AGENT; INSTRUCTIONS FROM
             THE LENDERS.

             The Administrative Agent agrees, upon the written request of the
Required Lenders, to take or refrain from taking any action of the type
specified as being within the Administrative Agent's rights, powers or
discretion herein, PROVIDED that the Administrative Agent shall not be required
to take any action which exposes the Administrative Agent to personal liability
or which is contrary to this Agreement or any other Loan Document or applicable
Law. In the absence of a request by the Required Lenders, the Administrative
Agent shall have authority, in its sole discretion, to take or not to take any
such action, unless this Agreement specifically requires the consent of the
Required Lenders or all of the Lenders. Any

                                     - 88 -
<Page>

action taken or failure to act pursuant to such instructions or discretion shall
be binding on the Lenders, subject to Section 9.6 [Exculpatory Provisions,
Etc.]. Subject to the provisions of Section 9.6, no Lender shall have any right
of action whatsoever against the Administrative Agent as a result of the
Administrative Agent acting or refraining from acting hereunder in accordance
with the instructions of the Required Lenders, or in the absence of such
instructions, in the absolute discretion of the Administrative Agent.

     9.5     REIMBURSEMENT AND INDEMNIFICATION OF ADMINISTRATIVE AGENT BY THE
             BORROWER.

             The Borrower unconditionally agrees to pay or reimburse the
Administrative Agent and hold the Administrative Agent harmless against (a)
liability for the payment of all reasonable out-of-pocket costs, expenses and
disbursements, including fees and expenses of counsel (including the allocated
costs of staff counsel), appraisers and environmental consultants, incurred by
the Administrative 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, and
(iv) 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 (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 Administrative 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 Administrative 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
Administrative Agent's gross negligence, willful misconduct or violation of law,
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 Administrative Agent's regular
employees and agents engaged periodically to visit or perform audits of the Loan
Parties' books, records and business properties to the extent provided in
Section 7.1.6.

             Neither the Administrative Agent nor any of its directors,
officers, employees, agents, attorneys or Affiliates shall (a) be liable to any
Lender for any action taken or omitted to be taken by it or them hereunder, or
in connection herewith including pursuant to any Loan

                                     - 89 -

Document, unless caused by its or their own gross negligence, willful misconduct
or violation of law, (b) be responsible in any manner to any of the Lenders for
the effectiveness, enforceability, genuineness, validity or the due execution of
this Agreement or any other Loan Documents or for any recital, representation,
warranty, document, certificate, report or statement herein or made or furnished
under or in connection with this Agreement or any other Loan Documents, or (c)
be under any obligation to any of the Lenders to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions
hereof or thereof on the part of the Loan Parties, or the financial condition of
the Loan Parties, or the existence or possible existence of any Event of Default
or Potential Default. No claim may be made by any of the Loan Parties, any
Lender, the Administrative Agent or any of their respective Subsidiaries against
the Administrative Agent, any Lender or any of their respective directors,
officers, employees, agents, attorneys or Affiliates, or any of them, for any
special, indirect or consequential damages or, to the fullest extent permitted
by Law, for any punitive damages in respect of any claim or cause of action
(whether based on contract, tort, statutory liability, or any other ground)
based on, arising out of or related to any Loan Document or the transactions
contemplated hereby or any act, omission or event occurring in connection
therewith, including the negotiation, documentation, administration or
collection of the Loans, and each of the Loan Parties, (for itself and on behalf
of each of its Subsidiaries), the Administrative Agent and each Lender hereby
waive, releases and agree never to sue upon any claim for any such damages,
whether such claim now exists or hereafter arises and whether or not it is now
known or suspected to exist in its favor. Each Lender agrees that, except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Administrative Agent hereunder or given to the Administrative
Agent for the account of or with copies for the Lenders, the Administrative
Agent and each of its directors, officers, employees, agents, attorneys or
Affiliates shall not have any duty or responsibility to provide any Lender with
any credit or other information concerning the business, operations, property,
condition (financial or otherwise), prospects or creditworthiness of the Loan
Parties which may come into the possession of the Administrative Agent or any of
its directors, officers, employees, agents, attorneys or Affiliates.

     9.7     REIMBURSEMENT AND INDEMNIFICATION OF ADMINISTRATIVE AGENT BY
             LENDERS.

             Each Lender agrees to reimburse and indemnify the Administrative
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 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 Administrative 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 Administrative
Agent hereunder or thereunder, PROVIDED that no Lender shall be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements (a) if the same results from
the Administrative Agent's gross negligence or willful misconduct, or (b) if
such Lender was not given notice of the subject claim and the opportunity to
participate in the defense thereof, at its expense (except that such Lender
shall remain liable to the extent such failure to give notice does not result in
a loss to

                                     - 90 -

the Lender), or (c) if the same results from a compromise and settlement
agreement entered into without the consent of such Lender, which shall not be
unreasonably withheld. In addition, each Lender agrees promptly upon demand to
reimburse the Administrative 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
Administrative Agent in connection with the Administrative Agent's periodic
audit of the Loan Parties' books, records and business properties.

     9.8     RELIANCE BY ADMINISTRATIVE AGENT.

             The Administrative 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 Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action hereunder unless it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action.

     9.9     NOTICE OF DEFAULT.

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

     9.10    NOTICES.

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

     9.11    LENDERS IN THEIR INDIVIDUAL CAPACITIES; ADMINISTRATIVE AGENT IN ITS
             INDIVIDUAL CAPACITY.

             With respect to its Commitment and the Loans made by it and any
other rights and powers given to it as a Lender hereunder or under any of the
other Loan Documents, the Administrative Agent shall have the same rights and
powers hereunder as any other Lender and may exercise the same as though it were
not the Administrative Agent, and the term "Lender" and "Lenders" shall, unless
the context otherwise indicates, include the Administrative Agent in its
individual capacity. PNC Bank and its Affiliates and each of the Lenders 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

                                     - 91 -
<Page>

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 Administrative Agent, as
though it were not acting as Administrative Agent hereunder and in the case of
each Lender, as though such Lender were not a Lender hereunder, in each case
without notice to or consent of the other Lenders. The Lenders acknowledge that,
pursuant to such activities, the Administrative 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 Administrative Agent shall be under no obligation to
provide such information to them, and (ii) accept fees and other consideration
from the Loan Parties for services in connection with this Agreement and
otherwise without having to account for the same to the Lenders.

     9.12    HOLDERS OF NOTES.

             The Administrative 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 Administrative
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.

     9.13    EQUALIZATION OF LENDERS.

             The Lenders and the holders of any participations in any Notes
agree among themselves that, with respect to all amounts received by any Lender
or any such holder for application on any Obligation hereunder or under any Note
or under any such participation, whether received by voluntary payment, by
realization upon security, by the exercise of the right of set-off or banker's
lien, by counterclaim or by any other non-pro rata source, equitable adjustment
will be made in the manner stated in the following sentence so that, in effect,
all such excess amounts will be shared ratably among the Lenders and such
holders in proportion to their interests in payments under the Notes, except as
otherwise provided in Section 3.4.3 [Administrative Agent's and Lender's
Rights], 4.4.2 [Replacement of a Lender] or 4.5 [Additional Compensation in
Certain Circumstances]. The Lenders or any such holder receiving any such amount
shall purchase for cash from each of the other Lenders an interest in such
Lender's Loans in such amount as shall result in a ratable participation by the
Lenders and each such holder in the aggregate unpaid amount under the Notes,
PROVIDED that if all or any portion of such excess amount is thereafter
recovered from the Lender or the holder making such purchase, such purchase
shall be rescinded and the purchase price restored to the extent of such
recovery, together with interest or other amounts, if any, required by law
(including court order) to be paid by the Lender or the holder making such
purchase.

     9.14    SUCCESSOR ADMINISTRATIVE AGENT.

             The Administrative Agent (i) may resign as Administrative Agent or
(ii) shall resign if such resignation is requested by the Required Lenders (if
the Administrative Agent is a

                                     - 92 -
<Page>

Lender, the Administrative Agent's Loans and its Commitment shall be considered
in determining whether the Required Lenders have requested such resignation) or
required by Section 4.4.2 [Replacement of a Lender], in either case of (i) or
(ii) by giving not less than thirty (30) days' prior written notice to the
Borrower. If the Administrative Agent shall resign under this Agreement, then
either (a) the Required Lenders shall appoint from among the Lenders a successor
agent for the Lenders, subject to the consent of the Borrower, such consent not
to be unreasonably withheld, or (b) if a successor agent shall not be so
appointed and approved within the thirty (30) day period following the
Administrative Agent's notice to the Lenders of its resignation, then the
Administrative Agent shall appoint, with the consent of the Borrower, such
consent not to be unreasonably withheld, a successor agent who shall serve as
Administrative Agent until such time as the Required Lenders appoint and the
Borrower consents to the appointment of a successor agent. Upon its appointment
pursuant to either clause (a) or (b) above, such successor agent shall succeed
to the rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent, effective upon its
appointment, and the former Administrative Agent's rights, powers and duties as
Administrative Agent shall be terminated without any other or further act or
deed on the part of such former Administrative Agent or any of the parties to
this Agreement. After the resignation of any Administrative Agent hereunder, the
provisions of this Section 9 shall inure to the benefit of such former
Administrative Agent and such former Administrative 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 Administrative Agent under this Agreement.

     9.15    ADMINISTRATIVE AGENT'S FEE.

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

     9.16    AVAILABILITY OF FUNDS.

             The Administrative Agent may assume that each Lender has made or
will make the proceeds of a Loan available to the Administrative Agent unless
the Administrative Agent shall have been notified by such Lender on or before
the later of (1) the close of Business on the Business Day preceding the
Borrowing Date with respect to such Loan or two (2) hours before the time on
which the Administrative Agent actually funds the proceeds of such Loan to the
Borrower (whether using its own funds pursuant to this Section 9.16 or using
proceeds deposited with the Administrative Agent by the Lenders and whether such
funding occurs before or after the time on which Lenders are required to deposit
the proceeds of such Loan with the Administrative Agent). The Administrative
Agent may, in reliance upon such assumption (but shall not be required to), make
available to the Borrower a corresponding amount. If such corresponding amount
is not in fact made available to the Administrative Agent by such Lender, the
Administrative Agent shall be entitled to recover such amount on demand from
such Lender (or, if such Lender fails to pay such amount forthwith upon such
demand from the Borrower) together with interest thereon, in respect of each day
during the period commencing on the date such amount was made available to the
Borrower and ending on the date the Administrative

                                     - 93 -
<Page>

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.

     9.17    CALCULATIONS.

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

     9.18    BENEFICIARIES.

             Except as expressly provided herein, the provisions of this
Section 9 are solely for the benefit of the Administrative Agent and the
Lenders, and the Loan Parties shall not have any rights to rely on or enforce
any of the provisions hereof. In performing its functions and duties under this
Agreement, the Administrative Agent shall act solely as agent of the Lenders and
does not assume and shall not be deemed to have assumed any obligation toward or
relationship of agency or trust with or for any of the Loan Parties.

                                10. MISCELLANEOUS

     10.1    MODIFICATIONS, AMENDMENTS OR WAIVERS.

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

                    10.1.1. INCREASE OF COMMITMENT; EXTENSION OF EXPIRATION
DATE.

                    Increase the amount of the Commitment of any Lender

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

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

                    10.1.3. RELEASE OF COLLATERAL OR GUARANTOR.

capital stock or other ownership interests of any Loan Party or its Subsidiary
or substantially all of the assets of any Loan Party, any Guarantor from its
Obligations under the Guaranty Agreement or any other security for any of the
Loan Parties' Obligations; or

                    10.1.4. MISCELLANEOUS.

                    Amend Section 4.2 [Pro Rata Treatment of Lenders], 9.6
[Exculpatory Provisions, Etc.] or 9.13 [Equalization of Lenders] or this Section
10.1, alter any provision regarding the pro rata treatment of the Lenders,
change the definition of Required Lenders, or change any requirement providing
for the Lenders or the Required Lenders to authorize the taking of any action
hereunder;

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

     10.2    NO IMPLIED WAIVERS; CUMULATIVE REMEDIES; WRITING REQUIRED.

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

     10.3    REIMBURSEMENT AND INDEMNIFICATION OF LENDERS BY THE BORROWER;
             TAXES.

             The Borrower agrees unconditionally upon demand to pay or reimburse
to each Lender and its Affiliates, directors, officers, employees, counsel,
agents and attorneys-in-fact (collectively, "Indemnitees") (other than the
Administrative Agent, as to which the Borrower's Obligations are set forth in
Section 9.5 [Reimbursement of Administrative Agent By Borrower, Etc.]) and to
save such Indemnitees 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 Lender
except with respect to (a) and (b) below), incurred by such Lender (a) in
connection with the administration and interpretation of this Agreement, and
other instruments and documents to be delivered hereunder, (b) relating to any
amendments, waivers or consents pursuant to the provisions hereof, (c) in
connection with the enforcement of this Agreement or any other Loan Document, or
collection of amounts due hereunder or thereunder or the proof and allowability
of any claim arising under this Agreement or any other Loan Document, whether in
bankruptcy or receivership proceedings or otherwise, and (d) in any workout or
restructuring or in connection with the protection, preservation, exercise or
enforcement of any of the terms hereof or of any rights hereunder or under any
other Loan Document or in connection with any foreclosure, collection or
bankruptcy proceedings, or (ii) all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against such Indemnitee, in its capacity as such, in any way relating to or
arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the performance by the parties hereto
of their respective obligations hereunder or the consumation of the transactions
contemplated hereby or thereby, (ii) any Loan or the use of the proceeds
therefrom, (iii) any actual or alleged presence or release of Regulated
Substances on or from any property owned or operated by the Borrower or any of
its Subsidiaries, or (iv) any claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory and regardless of whether any Indemnitee is a party thereto, , 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 are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted results from
such Indemnitee's gross negligence or willful misconduct, or (B) if the Borrower
was not given notice of the subject claim and the opportunity to participate in
the defense thereof, at its expense (except that the Borrower shall remain
liable to the extent such failure to give notice does not result in a loss to
the Borrower), or (C) if the same results from a compromise or settlement
agreement entered into without the consent of the Borrower, which shall not be
unreasonably withheld. The Lenders will attempt to minimize the fees and
expenses of legal counsel for the Lenders which are subject to reimbursement by
the Borrower hereunder by considering the usage of one law firm to represent the
Lenders and the Administrative 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 Administrative Agent or any Lender to be payable in connection with this
Agreement or any other Loan Document, and the Borrower agrees unconditionally to
save the Administrative Agent and the Lenders harmless from and against any and
all present or future

                                     - 96 -
<Page>

claims, liabilities or losses with respect to or resulting from any omission to
pay or delay in paying any such taxes, fees or impositions.

     10.4    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 3.2 [Interest Periods] with respect
to Interest Periods under the Euro-Rate 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.

     10.5    FUNDING BY BRANCH, SUBSIDIARY OR AFFILIATE.

                    10.5.1. NOTIONAL FUNDING.

                    Each Lender shall have the right from time to time, without
notice to the Borrower, to deem any branch, Subsidiary or Affiliate (which for
the purposes of this Section 10.5 shall mean any corporation or association
which is directly or indirectly controlled by or is under direct or indirect
common control with any corporation or association which directly or indirectly
controls such Lender) of such Lender to have made, maintained or funded any Loan
to which the Euro-Rate Option applies at any time, PROVIDED that immediately
following (on the assumption that a payment were then due from the Borrower to
such other office), and as a result of such change, the Borrower would not be
under any greater financial obligation pursuant to Section 4.5 [Additional
Compensation in Certain Circumstances] than it would have been in the absence of
such change. Notional funding offices may be selected by each Lender without
regard to such Lender's actual methods of making, maintaining or funding the
Loans or any sources of funding actually used by or available to such Lender.

                    10.5.2. ACTUAL FUNDING.

                    Each Lender shall have the right from time to time to make
or maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such
Lender to make or maintain such Loan subject to the last sentence of this
Section 10.5.2. If any Lender causes a branch, Subsidiary or Affiliate to make
or maintain any part of the Loans hereunder, all terms and conditions of this
Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the Loans to the same extent as if such Loans were
made or maintained by such Lender, but in no event shall any Lender's use of
such a branch, Subsidiary or Affiliate to make or maintain any part of the Loans
hereunder cause such Lender or such branch, Subsidiary or Affiliate to incur any
cost or expenses payable by the Borrower hereunder or require the Borrower to
pay any other compensation to any Lender (including any expenses incurred or

                                     - 97 -
<Page>

payable pursuant to Section 4.5 [Additional Compensation in Certain
Circumstances]) which would otherwise not be incurred.

                    (iv)    In the case of a facsimile transmission, when sent
to the applicable party's facsimile machine's telephone number if the party
sending such Notice receives confirmation of the delivery thereof from its own
facsimile machine;

                    (v)     In the case of electronic transmission, when

                    (vii)   If given by any other means (including by overnight

thereof to the Administrative Agent, and the Administrative Agent shall promptly
notify the other Lenders of its receipt of such Notice.

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

     10.8    GOVERNING LAW.

     10.11   SUCCESSORS AND ASSIGNS.

                    (i)     This Agreement shall be binding upon and shall inure
to the benefit of the Lenders, the Administrative 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 Lender may, at its own cost, make assignments of or sell
participations in all or any part of its Commitments and the Loans made by it to
one or more banks or other entities, subject to the consent of the Borrower and
the Administrative Agent with respect to any assignee, such consent not to be
unreasonably withheld, 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 Lender to an Affiliate of such Lender, (2) any assignment
by a Lender to a Person may not be made in amounts less than the lesser of
$5,000,000 or the amount of the assigning Lender's Commitment provided that
assignments may be made in amounts less than $5,000,000 if the assignment is
either (i) to another Lender, provided that the amount of the assigning Lender's
Commitment equals or exceeds $5,000,000 after giving effect to such assignment,
or (ii) to an Affiliate of the assigning Lender. In the case of an assignment,
upon receipt by the Administrative 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 Lender hereunder, the Commitments shall be
adjusted accordingly, and upon surrender of any Note subject to such assignment,
the Borrower shall execute and deliver a new Note to the assignee in an amount
equal to the amount of the Commitment assumed by it and a new Note to the
assigning Lender in an amount equal to the Commitment retained by it hereunder.
Any Lender which assigns any or all of its Commitment or Loans to a Person other
than an Affiliate of such Lender shall pay to the Administrative 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 8.2.3 [Set-off]

respect to changes of the type referenced in Sections 10.1.1 [Increase of
Commitment, Etc.], 10.1.2 [Extension of Payment, Etc.], or 10.1.3 [Release of

                    (ii)    Any assignee or participant which is not
incorporated under the Laws of the United States of America or a state thereof

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

     10.12   CONFIDENTIALITY.

                    10.12.1.    GENERAL.

                    The Administrative Agent and the Lenders 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 Administrative Agent and the Lenders shall be permitted to disclose

administration and enforcement of this Agreement, subject to agreement of such
Persons to maintain the confidentiality, (ii) to assignees and participants as

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.

                    10.12.2.    SHARING INFORMATION WITH AFFILIATES OF THE
LENDERS.

                    Each Loan Party acknowledges that from time to time
financial 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 Lender or by one or more Subsidiaries or
Affiliates of such Lender and each of the Loan Parties hereby authorizes each
Lender to share any information delivered to such Lender by such Loan Party and
its Subsidiaries pursuant to this Agreement, or in connection with the decision
of such Lender to enter into this Agreement, to any such Subsidiary or Affiliate
of such Lender, it being understood that any such Subsidiary or affiliate of any
Lender receiving such information shall be bound by the provisions of Section
10.12.1 as if it were a Lender hereunder. Such Authorization shall survive the
repayment of the Loans and other Obligations and the termination of the
Commitments.

             This Agreement may be executed by different parties hereto on any

shall be an original, and all such counterparts shall together constitute one
and the same instrument.

     10.14   ADMINISTRATIVE AGENT'S OR LENDER'S CONSENT.

             Whenever the Administrative Agent's or any Lender'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 Administrative
Agent and each Lender 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.

PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE. EACH LOAN PARTY, THE ADMINISTRATIVE AGENT AND THE LENDERS

     10.17   TAX WITHHOLDING CLAUSE.

             Each Lender or assignee or participant of a Lender that is not
incorporated under the Laws of the United States of America or a state thereof
(and, upon the written request of the

                                     - 102 -
<Page>

Administrative Agent, each other Lender or assignee or participant of a Lender)
agrees that it will deliver to each of the Borrower and the Administrative 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 Lender, assignee
or participant required to deliver to the Borrower and the Administrative Agent
a Withholding Certificate pursuant to the preceding sentence shall deliver such
valid Withholding Certificate as follows: (A) each Lender which is a party
hereto on the Closing Date shall deliver such valid Withholding Certificate at
least five (5) Business Days prior to the first date on which any interest or
fees are payable by the Borrower hereunder for the account of such Lender; (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 Administrative 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 Administrative Agent). Each Lender,
assignee or participant which so delivers a valid Withholding Certificate
further undertakes to deliver to each of the Borrower and the Administrative
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 Administrative Agent. Notwithstanding the submission of a Withholding
Certificate claiming a reduced rate of or exemption from U.S. withholding tax,
the Administrative Agent shall be entitled to withhold United States federal
income taxes at the full 30% withholding rate if in its reasonable judgment it
is required to do so under the due diligence requirements imposed upon a
withholding agent under Section 1.1441-7(b) of the Regulations. Further, the
Administrative Agent is indemnified under Section 1.1461-1(e) of the Regulations
against any claims and demands of any Lender or assignee or participant of a
Lender for the amount of any tax it deducts and withholds in accordance with
regulations under Section 1441 of the Internal Revenue Code.

     10.18   JOINDER OF GUARANTORS.

             Any Subsidiary of the Borrower which is required to join this
Agreement as a Guarantor pursuant to Section 7.2.10 [Subsidiaries, Partnerships
and Joint Ventures] shall execute and deliver to the Administrative 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 6.1
[First Loans] modified as appropriate to relate to such Subsidiary; and (iii)
documents necessary to grant and perfect Prior Security Interests to the
Administrative

                                     - 103 -
<Page>

Agent for the benefit of the Lenders and their Affiliates in all Collateral held
by such Subsidiary. The Loan Parties shall deliver such Guarantor Joinder and
related documents to the Administrative Agent within five (5) Business Days
after the date of the filing of such Subsidiary's articles of incorporation if
the 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.

     10.19   CO-LEAD ARRANGERS AND CO-DOCUMENTATION AGENTS.

             The Co-Lead Arrangers and Co-Documentation Agents shall have no
responsibilities, obligations or duties in their capacities as Co-Lead Arrangers
and Co-Documentation Agents.
