Rate Loan to a Eurodollar Loan, the Borrower shall provide telephonic notice to
the Initial Lender if such Lender is the sole lender at such time, or to the
Administrative Agent, followed promptly by a written Notice of
Continuation/Conversion, in the form of Exhibit 2.2 setting forth (i) whether
the Borrower wishes to continue or convert such Loans and (ii) if the request is
to continue a Eurodollar Loan or convert a Base Rate Loan to a Eurodollar Loan,
the Interest Period(s) applicable thereto. Notwithstanding anything herein to
the contrary, (A) except as provided in Section 3.11, Eurodollar Loans may only
be continued or converted into Base Rate Loans on the last day of the Interest
Period applicable thereto, (B) Eurodollar Loans may not be continued nor may
Base Rate Loans be converted into Eurodollar Loans during the existence and
continuation of a Default or an Event of Default, (C) any request to continue a
Eurodollar Loan that fails to comply with the terms hereof or any failure to
request a continuation of a Eurodollar Loan at the end of an Interest Period
shall constitute a conversion to a Base Rate Loan on the last day of the
applicable Interest Period and (D) any failure to state the Interest Period with
respect to the continuation of a Eurodollar Loan or the conversion of a Base
Rate Loan to a Eurodollar Loan shall constitute a request for a one month
Interest Period.

     2.3 Minimum Amounts.

     Each request for a conversion or continuation shall be subject to the
requirements that (a) each Eurodollar Loan shall be in a minimum amount of
$10,000,000 and in integral multiples of $1,000,000 in excess thereof, (b) each
Base Rate Loan shall be in a minimum amount of the lesser of $5,000,000 (and in
integral multiples of $1,000,000 in excess thereof) and (c) no more than four


                                      -24-







Eurodollar Loans shall be outstanding hereunder at any one time. For the
purposes of this Section 2.3, all Eurodollar Loans with the same Interest
Periods that begin and end on the same date shall be considered as one
Eurodollar Loan, but Eurodollar Loans with different Interest Periods, even if
they begin on the same date, shall be considered as separate Eurodollar Loans.

                                    SECTION 3

                     GENERAL PROVISIONS APPLICABLE TO LOANS

     3.1 Interest.

          (a) Interest Rate. Subject to Section 3.1(b), (i) all Base Rate Loans
     shall accrue interest at the Base Rate and (ii) all Eurodollar Loans shall
     accrue interest at the Adjusted Eurodollar Rate.

          (b) Default Rate of Interest. Upon the occurrence, and during the
     continuation of an Event of Default pursuant to Section 9.1(a), the
     principal of and, to the extent permitted by law, interest on the Loans and
     any other amounts owing hereunder or under the other Credit Documents
     (including without limitation fees and expenses) shall bear interest,
     payable on demand, at a per annum rate equal to 2% plus the rate which
     would otherwise be applicable (or if no rate is applicable, then the Base
     Rate plus two percent (2%) per annum).

          (c) Interest Payments. Interest on Loans shall be due and payable in
     arrears on each Interest Payment Date.

     3.2 Place and Manner of Payments.

     All payments of principal, interest, fees, expenses and other amounts to be
made by a Credit Party under this Credit Agreement shall be made unconditionally
and without any setoff, deduction, counterclaim, defense, recoupment or
withholding of any kind and received not later than 2:00 p.m. on the date when
due, in Dollars and in immediately available funds, by the Administrative Agent.
Payments received after such time shall be deemed to have been received on the
next Business Day. The Borrower shall, at the time it makes any payment under
this Credit Agreement, specify to the Administrative Agent the Loans, fees or
other amounts payable by the Borrower hereunder to which such payment is to be
applied (and in the event that it fails to specify, or if such application would
be inconsistent with the terms hereof, the Administrative Agent shall, subject
to Section 3.7, distribute such payment to the Lenders in such manner as the
Administrative Agent may reasonably deem appropriate). The Administrative Agent
will distribute such payments to the Lenders on the same Business Day if any
such payment is received at or before 2:00 p.m.; otherwise the Administrative
Agent will distribute such payment to the Lenders on the next succeeding
Business Day. Whenever any payment hereunder shall be stated to be due on a day
which is not a Business Day, the due date thereof shall be extended to the next
succeeding Business Day (subject to accrual of interest and fees for the period
of such extension), except that, in the case of Eurodollar Loans (or interest
payable with respect thereto), if the extension would cause the payment to be
made in the


                                      -25-







next following calendar month, then such payment shall instead be made on the
next preceding Business Day.

     3.3 Prepayments.

          (a) Voluntary Prepayments. The Borrower shall have the right to prepay
     Loans in whole or in part from time to time without premium or penalty;
     provided, however, that (i) Eurodollar Loans may only be prepaid on three
     Business Days' prior written notice to the Administrative Agent and (ii)
     each such partial prepayment of Eurodollar Loans or Base Rate Loans shall
     be in the minimum principal amount of $5,000,000 and integral multiples of
     $1,000,000. Amounts prepaid pursuant to this Section 3.3(a) shall be
     applied (A) first to the next scheduled amortization payment set forth in
     Section 2.1(d) and (B) second to the remaining scheduled amortization
     payments set forth in Section 2.1(d) on a pro rata basis. Within the
     foregoing parameters, amounts prepaid pursuant to this Section 3.3(a) shall
     be applied first to Base Rate Loans and then to Eurodollar Loans in direct
     order of Interest Period maturities. All prepayments under this Section
     3.3(a) shall be subject to Section 3.14.

          (b) Revision of Amortization Schedule. If the Borrower makes a
     prepayment in accordance with this Section 3.3, and the Initial Lender is
     not the sole Lender at the time, the Administrative Agent shall recalculate
     the outstanding principal amount of the Term Loans following such
     prepayment, reschedule the remaining amortization payments giving effect to
     such prepayment, and promptly distribute to the Borrower and to each of the
     Lenders a revised version of the schedule which appears in Section 2.1(d).

     3.4 [intentionally omitted]

     3.5 Payment in full at Maturity or Otherwise.

     The entire outstanding principal balance of all Loans, together with
accrued but unpaid interest and all other sums owing with respect thereto, shall
be due and payable in full, unless accelerated sooner pursuant to Section 9 on
the Maturity Date.

     3.6 Computations of Interest and Fees.

          (a) Except for Base Rate Loans that are based upon the Prime Rate, in
     which case interest shall be computed on the basis of the actual number of
     days elapsed over a year of 365 or 366 days, as the case may be, all
     computations of interest and fees hereunder shall be made on the basis of
     the actual number of days elapsed over a year of 360 days. Interest shall
     accrue from and include the date of borrowing (or continuation or
     conversion) but exclude the date of payment.

          (b) It is the intent of the Lenders and the Credit Parties to conform
     to and contract in strict compliance with applicable usury law from time to
     time in effect. All agreements between the Lenders and the Credit Parties
     are hereby limited by the provisions of this paragraph which shall override
     and control all such agreements, whether now


                                      -26-







     existing or hereafter arising and whether written or oral. In no way, nor
     in any event or contingency (including but not limited to prepayment or
     acceleration of the maturity of any obligation), shall the interest taken,
     reserved, contracted for, charged, or received under this Credit Agreement,
     under the Notes or otherwise, exceed the maximum nonusurious amount
     permissible under applicable law. If, from any possible construction of any
     of the Credit Documents or any other document, interest would otherwise be
     payable in excess of the maximum nonusurious amount, any such construction
     shall be subject to the provisions of this paragraph and such documents
     shall be automatically reduced to the maximum nonusurious amount permitted
     under applicable law, without the necessity of execution of any amendment
     or new document. If any Lender shall ever receive anything of value which
     is characterized as interest on the Loans under applicable law and which
     would, apart from this provision, be in excess of the maximum nonusurious
     amount, an amount equal to the amount which would have been excessive
     interest shall, without penalty, be applied to the reduction of the
     principal amount owing on the Loans and not to the payment of interest, or
     refunded to the Borrower or the other payor thereof if and to the extent
     such amount which would have been excessive exceeds such unpaid principal
     amount of the Loans. The right to demand payment of the Loans or any other
     Indebtedness evidenced by any of the Credit Documents does not include the
     right to accelerate the payment of any interest which has not otherwise
     accrued on the date of such demand, and the Lenders do not intend to charge
     or receive any unearned interest in the event of such demand. All interest
     paid or agreed to be paid to the Lenders with respect to the Loans shall,
     to the extent permitted by applicable law, be amortized, prorated,
     allocated, and spread throughout the full stated term (including any
     renewal or extension) of the Loans so that the amount of interest on
     account of such Indebtedness does not exceed the maximum nonusurious amount
     permitted by applicable law.

     3.7 Pro Rata Treatment.

     Except to the extent otherwise provided herein or when the Initial Lender
is the sole Lender, each payment or prepayment of principal of any Loan, and
each conversion or continuation of any Loan shall (except as otherwise provided
in Section 3.11) be allocated pro rata among the Lenders in accordance with the
respective principal amounts of the outstanding Loans and Participation
Interests of the Lenders); provided that, in the event any amount paid to any
Lender pursuant to this Section 3.7 is rescinded or must otherwise be returned
by the Administrative Agent, each Lender shall, upon the request of the
Administrative Agent, repay to the Administrative Agent the amount so paid to
such Lender, with interest for the period commencing on the date such payment is
returned by the Administrative Agent until the date the Administrative Agent
receives such repayment at a rate per annum equal to, during the period to but
excluding the date two Business Days after such request, the Federal Funds Rate,
and thereafter, the Base Rate plus two percent (2%) per annum.

     3.8 Sharing of Payments.

     The Lenders agree among themselves that, except to the extent otherwise
provided herein, in the event that any Lender shall obtain payment in respect of
any Loan, or any other obligation owing to such Lender under this Credit
Agreement through the exercise of a right of setoff, banker's


                                      -27-







lien or counterclaim, or pursuant to a secured claim under Section 506 of the
Bankruptcy Code or other security or interest arising from, or in lieu of, such
secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, in excess
of its pro rata share of such payment as provided for in this Credit Agreement,
such Lender shall promptly pay in cash or purchase from the other Lenders a
participation in such Loans, and other obligations in such amounts, and make
such other adjustments from time to time, as shall be equitable to the end that
all Lenders share such payment in accordance with their respective ratable
shares as provided for in this Credit Agreement. The Lenders further agree among
themselves that if payment to a Lender obtained by such Lender through the
exercise of a right of setoff, banker's lien, counterclaim or other event as
aforesaid shall be rescinded or must otherwise be restored, each Lender which
shall have shared the benefit of such payment shall, by payment in cash or a
repurchase of a participation theretofore sold, return its share of that benefit
(together with its share of any accrued interest payable with respect thereto)
to each Lender whose payment shall have been rescinded or otherwise restored.
The Borrower agrees that any Lender so purchasing such a participation may, to
the fullest extent permitted by law, exercise all rights of payment, including
setoff, banker's lien or counterclaim, with respect to such participation as
fully as if such Lender were a holder of such Loan, or other obligation in the
amount of such participation. Except as otherwise expressly provided in this
Credit Agreement, if any Lender or the Administrative Agent shall fail to remit
to any other Lender an amount payable by such Lender or the Administrative Agent
to such other Lender pursuant to this Credit Agreement on the date when such
amount is due, such payments shall be made together with interest thereon for
each date from the date such amount is due until the date such amount is paid to
the Administrative Agent or such other Lender at a rate per annum equal to the
Federal Funds Rate. If under any applicable bankruptcy, insolvency or other
similar law, any Lender receives a secured claim in lieu of a setoff to which
this Section 3.8 applies, such Lender shall, to the extent practicable, exercise
its rights in respect of such secured claim in a manner consistent with the
rights of the Lenders under this Section 3.8 to share in the benefits of any
recovery on such secured claim.

     3.9 Capital Adequacy/Regulation D.

          (a) If, after the date thereof, any Lender determines that the
     introduction after the Closing Date of any law, rule or regulation or other
     Requirement of Law regarding capital adequacy or any change therein or in
     the interpretation thereof, or compliance by such Lender (or its Lending
     Office) therewith, has or would have the effect of reducing the rate of
     return on the capital or assets of such Lender or any corporation
     controlling such Lender as a consequence of such Lender's obligations
     hereunder (taking into consideration its policies with respect to capital
     adequacy and such Lender's desired return on capital), then from time to
     time upon demand of such Lender (with a copy of such demand to the
     Administrative Agent), the Borrower shall pay to such Lender such
     additional amounts as will compensate such Lender for such reduction.

          (b) The Borrower shall pay to each Lender, as long as such Lender
     shall be required under regulations of the Board of Governors of the
     Federal Reserve System of the United States of America to maintain reserves
     with respect to liabilities or assets consisting of or including
     Eurocurrency funds or deposits (currently known as "Eurocurrency
     liabilities"), additional interest on the unpaid principal amount of each
     Eurodollar Loan


                                      -28-







     equal to (i) (A) the applicable Eurodollar Rate divided by (B) one minus
     the Eurodollar Reserve Percentage minus (ii) the applicable Eurodollar
     Rate. Such additional interest shall be due and payable on each date on
     which interest is payable on such Loan; provided the Borrower shall have
     received at least five days' prior notice (with a copy to the
     Administrative Agent) of such additional interest from such Lender. If a
     Lender fails to give notice five days prior to the relevant Interest
     Payment Date, such additional interest shall be due and payable five days
     from the receipt by the Borrower of such notice.

     3.10 Inability To Determine Interest Rate.

     If the Administrative Agent (the Initial Lender if it is the sole Lender)
determines (which determination shall be conclusive and binding upon the
Borrower) in connection with any request for a Eurodollar Loan or a conversion
to or continuation of a Eurodollar Loan that (a) Dollar deposits are not being
offered to banks in the applicable offshore Dollar market for the applicable
amount and Interest Period of such Eurodollar Loan, (b) adequate and reasonable
means do not exist for determining the Eurodollar Rate for such Eurodollar Loan,
or (c) the Eurodollar Rate for such Eurodollar Loan does not adequately and
fairly reflect the cost to the Lenders of funding such Eurodollar Loan, the
Administrative Agent will promptly notify the Borrower and all the Lenders.
Thereafter, the obligation of the Lenders to make or maintain Eurodollar Loans
shall be suspended until the Administrative Agent revokes such notice. Upon
receipt of such notice, the Borrower may revoke any pending Notice of Borrowing
or Notice of Continuation/Conversion with respect to Eurodollar Loans or,
failing that, will be deemed to have converted such request into a request for a
borrowing of or conversion into a Base Rate Loan in the amount specified
therein.

     3.11 Illegality.

     If any Lender determines that any Requirement of Law has made it unlawful,
or that any Governmental Authority has asserted that it is unlawful, for any
Lender or its applicable Lending Office to make, maintain or fund Eurodollar
Loans, or materially restricts the authority of such Lender to purchase or sell,
or to take deposits of, Dollars in the applicable offshore Dollar market, or to
determine or charge interest rates based upon the Eurodollar Rate, then, on
notice thereof by such Lender to the Borrower through the Administrative Agent,
any obligation of such Lender to make or continue Eurodollar Loans or to convert
Base Rate Loans to Eurodollar Loans shall be suspended until such Lender
notifies the Administrative Agent and the Borrower that the circumstances giving
rise to such determination no longer exist. Upon receipt of such notice, the
Borrower shall, upon demand from such Lender (with a copy to the Administrative
Agent), prepay or, if applicable, convert all Eurodollar Loans of such Lender to
Base Rate Loans, either on the last day of the Interest Period thereof, if such
Lender may lawfully continue to maintain such Eurodollar Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such
Eurodollar Loans. Upon any such prepayment or conversion, the Borrower shall
also pay interest on the amount so prepaid or converted, together with any
amounts due with respect thereto pursuant to Section 3.14. Each Lender agrees to
designate a different Lending Office if such designation will avoid the need for
such notice and will not, in the good faith judgment of such Lender, otherwise
be materially disadvantageous to such Lender.


                                      -29-







     3.12 Requirements of Law.

     If any Lender determines that as a result of the introduction of or any
change in, or in the interpretation of, any Requirement of Law, or such Lender's
compliance therewith, there shall be any increase in the cost to such Lender of
agreeing to make or making, funding or maintaining Eurodollar Loans or a
reduction in the amount received or receivable by such Lender in connection with
any of the foregoing (excluding for purposes of this subsection (a) any such
increased costs or reduction in amount resulting from (i) Taxes or Other Taxes
(as to which Section 3.13 shall govern) and (ii) reserve requirements utilized
in the determination of the Eurodollar Rate), then from time to time, within 10
days of demand of such Lender (with a copy of such demand to the Administrative
Agent), the Borrower shall pay to such Lender such additional amounts as will
compensate such Lender for such increased cost or reduction in yield.

     3.13 Taxes.

          (a) Any and all payments by a Credit Party to or for the account of
     the Administrative Agent or any Lender under any Credit Document shall be
     made free and clear of and without deduction for any and all present or
     future income, stamp or other taxes, duties, levies, imposts, deductions,
     assessments, fees, withholdings or similar charges, and all liabilities
     with respect thereto, but excluding, in the case of the Administrative
     Agent and each Lender, taxes imposed on or measured by its net income, and
     franchise taxes imposed on it (in lieu of net income taxes), by the
     jurisdiction (or any political subdivision thereof) under the laws of which
     the Administrative Agent or such Lender, as the case may be, is organized
     or maintains its Lending Office (all such non-excluded present or future
     income, stamp or other taxes, duties, levies, imposts, deductions,
     assessments, fees, withholdings or similar charges, and liabilities being
     hereinafter referred to as "Taxes"). If a Credit Party shall be required by
     any Requirement of Law to deduct any Taxes from or in respect of any sum
     payable under any Credit Document to the Administrative Agent or any
     Lender, (i) the sum payable shall be increased as necessary so that after
     making all required deductions (including deductions applicable to
     additional sums payable under this Section 3.13(a)), the Administrative
     Agent or such Lender, as the case may be, receives an amount equal to the
     sum it would have received had no such deductions been made, (ii) such
     Credit Party shall make such deductions, (iii) such Credit Party shall pay
     the full amount deducted to the relevant taxation authority or other
     Governmental Authority in accordance with applicable Requirements of Law,
     and (iv) within 30 days after the date of such payment, such Credit Party
     shall furnish to the Administrative Agent (which shall forward the same to
     such Lender) the original or a certified copy of a receipt evidencing
     payment thereof, to the extent such receipt is issued therefor, or other
     written proof of payment thereof that is reasonably satisfactory to the
     Administrative Agent.

          (b) In addition, each Credit Party agrees to pay any and all present
     or future stamp, court or documentary taxes and any other excise or
     property taxes or charges or similar levies which arise from any payment
     made under any Credit Document or from


                                      -30-







     the execution, delivery, performance, enforcement or registration of, or
     otherwise with respect to, any Credit Document (hereinafter referred to as
     "Other Taxes").

          (c) If a Credit Party shall be required to deduct or pay any Taxes or
     Other Taxes from or in respect of any sum payable under any Credit Document
     to the Administrative Agent or any Lender, such Credit Party shall also pay
     to the Administrative Agent (for the account of such Lender) or to such
     Lender, at the time interest is paid, such additional amount that such
     Lender reasonably specifies by written notice to such Credit Party as
     necessary to preserve the after-tax yield (after factoring in all taxes,
     including taxes imposed on or measured by net income) such Lender would
     have received if such Taxes or Other Taxes had not been imposed; provided
     that if such Lender fails to provide such notice to such Credit Party
     before the date which is five days prior to the date such interest is paid,
     such Credit Party shall pay at the time such interest is paid such amount
     as such Credit Party reasonably estimates will preserve such Lender's
     after-tax yield (after factoring in only such Taxes or Other Taxes) and pay
     the balance within five days after receiving such notice.

          (d) Each Credit Party agrees to indemnify the Administrative Agent and
     each Lender for (i) the full amount of Taxes and Other Taxes (including any
     Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts
     payable under this Section 3.13(d)) paid by the Administrative Agent and
     such Lender, and (ii) any liability (including penalties, interest and
     reasonable expenses) arising therefrom or with respect thereto.

          (e) In the case of any payment hereunder or under any other Credit
     Document by or on behalf of a Credit Party through an account or branch
     outside the United States, or on behalf of a Credit Party by a payor that
     is not a United States person, if such Credit Party determines that no
     taxes are payable in respect thereof, such Credit Party shall furnish, or
     shall cause such payor to furnish, to the Administrative Agent, an opinion
     of counsel reasonably acceptable to the Administrative Agent stating that
     such payment is exempt from Taxes. For purposes of this subsection (e), the
     terms "United States" and "United States person" shall have the meanings
     specified in Section 7701 of the Code.

          (f) Each Lender that is a foreign corporation, foreign partnership or
     foreign trust within the meaning of the Code shall deliver to the
     Administrative Agent, prior to receipt of any payment subject to
     withholding under the Code, two duly signed completed copies of either IRS
     Form W-8BEN or any successor thereto (relating to such Lender and entitling
     it to an exemption from, or reduction of, withholding tax on all payments
     to be made to such Lender by the Credit Parties pursuant to this Credit
     Agreement) or IRS Form W-8ECI or any successor thereto (relating to all
     payments to be made to such Lender by a Credit Party pursuant to this
     Credit Agreement), as appropriate, or such other evidence satisfactory to
     the Borrower and the Administrative Agent that such Lender is entitled to
     an exemption from, or reduction of, United States withholding tax.
     Thereafter and from time to time, each such Lender shall (i) promptly
     submit to the Administrative Agent such additional duly completed and
     signed copies of one of such forms (or such successor forms as shall be
     adopted from time to time by the relevant


                                      -31-







     United States taxing authorities), as appropriate, as may reasonably be
     requested by the Borrower or the Administrative Agent and then be available
     under then current United States laws and regulations to avoid, or such
     evidence as is satisfactory to the Borrower and the Administrative Agent of
     any available exemption from or reduction of, United States withholding
     taxes in respect of all payments to be made to such Lender by the Borrower
     pursuant to this Credit Agreement, (ii) promptly notify the Administrative
     Agent of any change in circumstances which would modify or render invalid
     any claimed exemption or reduction, and (iii) take such steps as shall not
     be materially disadvantageous to it, in the reasonable judgment of such
     Lender, and as may be reasonably necessary (including the re-designation of
     its Lending Office) to avoid any Requirement of Law that the Credit Parties
     make any deduction or withholding for taxes from amounts payable to such
     Lender. If the forms or other evidence provided by such Lender at the time
     such Lender first becomes a party to this Credit Agreement indicate a
     United States interest withholding tax rate in excess of zero, withholding
     tax at such rate shall be considered excluded from Taxes unless and until
     such Lender provides the appropriate forms certifying that a lesser rate
     applies, whereupon withholding tax at such lesser rate only shall be
     considered excluded from Taxes for periods governed by such forms;
     provided, however, that, if at the date of any assignment pursuant to which
     a Lender becomes a party to this Credit Agreement, the Lender assignor was
     entitled to payments under subsection (a) of this Section 3.13 in respect
     of United States withholding tax with respect to interest paid at such
     date, then, to such extent, the term Taxes shall include (in addition to
     withholding taxes that may be imposed in the future or other amounts
     otherwise includable in Taxes) United States withholding tax, if any,
     applicable with respect to the Lender assignee on such date. If such Lender
     fails to deliver the above forms or other evidence, then the Administrative
     Agent may withhold from any interest payment to such Lender an amount equal
     to the applicable withholding tax imposed by Sections 1441 and 1442 of the
     Code, without reduction. If any Governmental Authority asserts that the
     Administrative Agent did not properly withhold any tax or other amount from
     payments made in respect of such Lender, such Lender shall indemnify the
     Administrative Agent therefor, including all penalties and interest, any
     taxes imposed by any jurisdiction on the amounts payable to the
     Administrative Agent under this Section 3.13(f), and costs and expenses
     (including Attorney Costs) of the Administrative Agent. For any period with
     respect to which a Lender has failed to provide the Borrower with the above
     forms or other evidence (other than if such failure is due to a change in
     the applicable law, or in the interpretation or application thereof,
     occurring after the date on which such form or other evidence originally
     was required to be provided or if such form or other evidence otherwise is
     not required, such Lender shall not be entitled to indemnification under
     subsection (a) or (c) of this Section 3.13 with respect to Taxes imposed by
     the United States by reason of such failure; provided, however, that should
     a Lender become subject to Taxes because of its failure to deliver such
     form or other evidence required hereunder, the Borrower shall take such
     steps as such Lender shall reasonably request to assist such Lender in
     recovering such Taxes. The obligation of the Lenders under this Section
     3.13(f) shall survive the payment of all Credit Party Obligations and the
     resignation or replacement of the Administrative Agent.


                                      -32-







          (g) In the event that an additional payment is made under Section
     3.13(a) or (c) for the account of any Lender and such Lender, in its
     reasonable judgment, determines that it has finally and irrevocably
     received or been granted a credit against or release or remission for, or
     repayment of, any tax paid or payable by it in respect of or calculated
     with reference to the deduction or withholding giving rise to such payment,
     such Lender shall, to the extent that it determines that it can do so
     without prejudice to the retention of the amount of such credit, relief,
     remission or repayment, pay to the Borrower such amount as such Lender
     shall, in its reasonable judgment, have determined to be attributable to
     such deduction or withholding and which will leave such Lender (after such
     payment) in no worse position than it would have been in if the Borrower
     had not been required to make such deduction or withholding. Nothing herein
     contained shall interfere with the right of a Lender to arrange its tax
     affairs in whatever manner it thinks fit nor oblige any Lender to claim any
     tax credit or to disclose any information relating to its tax affairs or
     any computations in respect thereof or require any Lender to do anything
     that would prejudice its ability to benefit from any other credits,
     reliefs, remissions or repayments to which it may be entitled.

     3.14 Compensation.

     Upon the written demand of any Lender, the Borrower shall promptly
compensate such Lender for and hold such Lender harmless from any loss, cost or
expense incurred by it as a result of:

          (a) any continuation, conversion, payment or prepayment of any
     Eurodollar Loan on a day other than the last day of the Interest Period for
     such Eurodollar Loan (whether voluntary, mandatory, automatic, by reason of
     acceleration, or otherwise); or

          (b) any failure by the Borrower (for a reason other than the failure
     of such Lender to make a Eurodollar Loan) to prepay, borrow, continue or
     convert any Eurodollar Loan on the date or in the amount previously
     requested by the Borrower.

The amount each such Lender shall be compensated pursuant to this Section 3.14
shall include, without limitation, (i) any loss incurred by such Lender in
connection with the re-employment of funds prepaid, repaid, not borrowed or
paid, as the case may be and (ii) any reasonable out-of-pocket expenses
(including Attorney Costs) incurred and reasonably attributable thereto.

For purposes of calculating amounts payable by the Borrower to the Lenders under
this Section 3.14, each Lender may deem that it funded each Eurodollar Loan made
by it at the Eurodollar Rate for such Eurodollar Loan by a matching deposit or
other borrowing in the applicable offshore Dollar interbank market for a
comparable amount and for a comparable period, whether or not such Eurodollar
Loan was in fact so funded.

     3.15 Determination and Survival of Provisions.

     All determinations by the Administrative Agent or a Lender of amounts owing
under Sections 3.9 through 3.14, inclusive, shall, absent manifest error, be
conclusive and binding on


                                      -33-







the parties hereto. In determining such amount, the Administrative Agent or such
Lender may use any reasonable averaging and attribution methods. Section 3.9
through 3.14, inclusive, shall survive the termination of this Credit Agreement
and the payment of all Credit Party Obligations.

     3.16 Notification by Lenders.

     Subject to Section 3.13(c), each Lender shall notify the Borrower (and any
applicable Credit Party) of any event that will entitle such Lender to
compensation under Section 3.9, 3.12, 3.13 or 3.14 as promptly as practicable,
but in any event within 90 days after such Lender obtains actual knowledge
thereof; provided, however, that if any Lender fails to give such notice within
90 days after it obtains actual knowledge of such an event, such Lender shall,
with respect to compensation payable pursuant to Section 3.9, 3.12, 3.13 or 3.14
in respect of any costs resulting from such event, only be entitled to payment
under Section 3.9, 3.12, 3.13 or 3.14 for costs incurred from and after the date
90 days prior to the date that such Lender gives such notice. If requested by
the Borrower, each Lender will furnish to Borrower within ten Business Days of
the time the Lender requests compensation under Section 3.9, 3.12, 3.13 or 3.14,
a certificate setting forth the basis, amount and reasonable detail of
computation of each request by such Lender for compensation under Section 3.9,
3.12, 3.13 or 3.14, which certificate shall, except for demonstrable error, be
final, conclusive and binding for all purposes.

     3.17 Mitigation; Mandatory Assignment.

     Each Lender shall use reasonable efforts to avoid or mitigate any increased
cost or suspension of the availability of an interest rate under Sections 3.9
through 3.14 above to the greatest extent practicable (including transferring
the Loans to another Lending Office or Affiliate of a Lender) unless, in the
reasonable opinion of such Lender, such efforts would be likely to have an
adverse effect upon it. In the event a Lender makes a request to the Borrower
for additional payments in accordance with Section 3.9, 3.11, 3.12, 3.13 or
3.14, then, provided that no Default or Event of Default has occurred and is
continuing at such time, the Borrower may, at its own expense (such expense to
include, without limitation, any transfer fee payable to the Administrative
Agent under Section 11.3(b)) and in its sole discretion, require such Lender to
transfer and assign in whole (but not in part), without recourse (in accordance
with and subject to the terms and conditions of Section 11.3(b)), all of its
interests, rights and obligations under this Credit Agreement to an Eligible
Assignee which shall assume such assigned obligations (which assignee may be
another Lender, if a Lender accepts such assignment); provided that (a) such
assignment shall not conflict with any law, rule or regulation or order of any
court or other Governmental Authority and (b) the Borrower or such assignee
shall have paid to the assigning Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the portion of
the Loans hereunder held by such assigning Lender and all other amounts owed to
such assigning Lender hereunder, including amounts owed pursuant to Sections 3.9
through 3.14 hereof.


                                      -34-







                                    SECTION 4

                                    GUARANTY

     4.1 Guaranty of Payment.

     Subject to Section 4.7 below, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Lender and the Administrative
Agent the prompt payment of the Credit Party Obligations in full when due
(whether at stated maturity, as a mandatory prepayment, by acceleration or
otherwise) and the timely performance of all other obligations under the Credit
Documents. This Guaranty is a guaranty of payment and not of collection and is a
continuing guaranty and shall apply to all Credit Party Obligations whenever
arising.

     4.2 Obligations Unconditional.

     The obligations of the Guarantors hereunder are absolute and unconditional,
irrespective of the value, genuineness, validity, regularity or enforceability
of any of the Credit Documents, or any other agreement or instrument referred to
therein, to the fullest extent permitted by applicable law, irrespective of any
other circumstance whatsoever which might otherwise constitute a legal or
equitable discharge or defense of a surety or guarantor. Each Guarantor agrees
that this Guaranty may be enforced by the Lenders without the necessity at any
time of resorting to or exhausting any other security or collateral and without
the necessity at any time of having recourse to the Notes or any other of the
Credit Documents or any collateral, if any, hereafter securing the Credit Party
Obligations or otherwise and each Guarantor hereby waives the right to require
the Lenders to proceed against the Borrower or any other Person (including a
co-guarantor) or to require the Lenders to pursue any other remedy or enforce
any other right. Each Guarantor further agrees that it shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other Guarantor of the Credit Party Obligations for amounts paid under this
Guaranty until such time as the Lenders have been paid in full and all
Commitments under the Credit Agreement have been terminated. Each Guarantor
further agrees that nothing contained herein shall prevent the Lenders from
suing on the Notes or any of the other Credit Documents or foreclosing its
security interest in or Lien on any collateral, if any, securing the Credit
Party Obligations or from exercising any other rights available to it under this
Credit Agreement, the Notes, any other of the Credit Documents, or any other
instrument of security, if any, and the exercise of any of the aforesaid rights
and the completion of any foreclosure proceedings shall not constitute a
discharge of any of such Guarantor's obligations hereunder; it being the purpose
and intent of each Guarantor that its obligations hereunder shall be absolute,
independent and unconditional under any and all circumstances. Neither any
Guarantor's obligations under this Guaranty nor any remedy for the enforcement
thereof shall be impaired, modified, changed or released in any manner
whatsoever by an impairment, modification, change, release or limitation of the
liability of the Borrower or by reason of the bankruptcy or insolvency of the
Borrower. Each Guarantor waives any and all notice of the creation, renewal,
extension or accrual of any of the Credit Party Obligations and notice of or
proof of reliance of by the Administrative Agent or any Lender upon this
Guaranty or acceptance of this Guaranty. The Credit Party Obligations, and any
of them, shall conclusively be deemed to have been created, contracted or
incurred, or renewed, extended, amended or waived, in reliance upon this
Guaranty. All dealings between the Borrower and any of the Guarantors, on the
one hand, and


                                      -35-







the Administrative Agent and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon this
Guaranty. The Guarantors further agree to all rights of set-off as set forth in
Section 11.2.

     4.3 Modifications.

     Each Guarantor agrees that (a) all or any part of the collateral, if any,
now or hereafter held for the Credit Party Obligations, if any, may be
exchanged, compromised or surrendered from time to time; (b) the Lenders shall
not have any obligation to protect, perfect, secure or insure any such security
interests, liens or encumbrances now or hereafter held, if any, for the Credit
Party Obligations or the properties subject thereto; (c) the time or place of
payment of the Credit Party Obligations may be changed or extended, in whole or
in part, to a time certain or otherwise, and may be renewed or accelerated, in
whole or in part; (d) the Borrower and any other party liable for payment under
the Credit Documents may be granted indulgences generally; (e) any of the
provisions of the Notes or any of the other Credit Documents may be modified,
amended or waived; (f) any party (including any co-guarantor) liable for the
payment thereof may be granted indulgences or be released; and (g) any deposit
balance for the credit of the Borrower or any other party liable for the payment
of the Credit Party Obligations or liable upon any security therefor may be
released, in whole or in part, at, before or after the stated, extended or
accelerated maturity of the Credit Party Obligations, all without notice to or
further assent by such Guarantor, which shall remain bound thereon,
notwithstanding any such exchange, compromise, surrender, extension, renewal,
acceleration, modification, indulgence or release.

     4.4 Waiver of Rights.

     Each Guarantor expressly waives to the fullest extent permitted by
applicable law: (a) notice of acceptance of this Guaranty by the Lenders and of
all extensions of credit to the Borrower by the Lenders; (b) presentment and
demand for payment or performance of any of the Credit Party Obligations; (c)
protest and notice of dishonor or of default (except as specifically required in
the Credit Agreement) with respect to the Credit Party Obligations or with
respect to any security therefor; (d) notice of the Lenders obtaining, amending,
substituting for, releasing, waiving or modifying any security interest, lien or
encumbrance, if any, hereafter securing the Credit Party Obligations, or the
Lenders' subordinating, compromising, discharging or releasing such security
interests, liens or encumbrances, if any; and (e) all other notices to which
such Guarantor might otherwise be entitled.

     4.5 Reinstatement.

     The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Credit Party Obligations is
rescinded or must be otherwise restored by any holder of any of the Credit Party
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Administrative Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, reasonable Attorney Costs) incurred by
the Administrative Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any


                                      -36-







claim alleging that such payment constituted a preference, fraudulent transfer
or similar payment under any bankruptcy, insolvency or similar law.

     4.6 Remedies.

     The Guarantors agree that, as between the Guarantors, on the one hand, and
the Administrative Agent and the Lenders, on the other hand, the Credit Party
Obligations may be declared to be forthwith due and payable as provided in
Section 9 (and shall be deemed to have become automatically due and payable in
the circumstances provided in Section 9) notwithstanding any stay, injunction or
other prohibition preventing such declaration (or preventing such Credit Party
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or such Credit Party
Obligations being deemed to have become automatically due and payable), such
Credit Party Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors.

     4.7 Limitation of Guaranty.

     Notwithstanding any provision to the contrary contained herein or in any of
the other Credit Documents, to the extent the obligations of any Guarantor shall
be adjudicated to be invalid or unenforceable for any reason (including, without
limitation, because of any applicable state or federal law relating to
fraudulent conveyances or transfers) then the obligations of such Guarantor
hereunder shall be limited to the maximum amount that is permissible under
applicable law (whether federal or state or otherwise and including, without
limitation, the Bankruptcy Code).

     4.8 Rights of Contribution.

     The Credit Parties agree among themselves that, in connection with payments
made hereunder, each Credit Party shall have contribution rights against the
other Credit Parties as permitted under applicable law. Such contribution rights
shall be subordinate and subject in right of payment to the obligations of the
Credit Parties under the Credit Documents and no Credit Party shall exercise
such rights of contribution until all Credit Party Obligations have been paid in
full and the Commitments terminated.

     4.9 Release of Guarantors.

     Subject to Section 7.12(b), if any of the Guarantors shall cease to be a
Material Domestic Subsidiary of the Borrower for any reason subject to and in
accordance with the terms of the Credit Agreement, then such Guarantor shall,
automatically and without any further action on the part of any party to any
Credit Document, and upon notice to the Administrative Agent, be fully released
and discharged from all its liabilities and obligations under or in respect of
the Credit Documents to which such Guarantor is a party (other than liabilities
and obligations resulting from a demand on such Guarantor's Guaranty pursuant to
Section 9.2) and, promptly upon the request of the Borrower and at the expense
of the Borrower, the Administrative Agent shall execute such documents and take
such other action as is reasonably requested by the Borrower to evidence the
release and discharge of such Guarantor from all such liabilities and
obligations and


                                      -37-







shall, if applicable, certify to the Borrower that such Guarantor has no
liabilities or obligations resulting from a demand on such Guarantor's Guaranty
pursuant to Section 9.2.

                                    SECTION 5

     the effect of which default or other event or condition is to cause, or
     permit, the holder or holders of such Indebtedness (or trustee or agent on
     behalf of such holders, if any) to require (determined without regard to
     whether any notice or lapse of time is required) any such Indebtedness to
     become due prior to its stated maturity; or (B) any such Indebtedness shall
     be declared due and payable, or required to be prepaid other than by a
     regularly scheduled required prepayment prior to the stated maturity
     thereof; or (C) any such Indebtedness shall mature and remain unpaid.

     extent not paid, covered by insurance provided by a carrier who has
     acknowledged coverage or covered by an indemnification from Corning
     Incorporated or SmithKline Beecham PLC) and such judgments, orders or
     decrees (i) are the subject of any enforcement proceeding commenced by any

     412 of the Code, whether or not waived, shall exist with respect to any
     Plan, other than a Multiemployer Plan, or any Lien shall arise on the
     assets of the Borrower, any Subsidiary of the Borrower or any ERISA
     Affiliate in favor of the PBGC or a Plan, other than a Multiemployer Plan;
     (ii) an ERISA Event shall occur with respect to a Single Employer Plan,
     which is reasonably likely to result in the termination of such Plan for
     purposes of Title IV of ERISA; (iii) an ERISA Event shall occur with
     respect to a Multiemployer Plan or Multiple Employer Plan, which is
     reasonably likely to result in (A) the termination of such plan for

                                      -60-







          (j) Ownership. There shall occur a Change of Control.

          (k) Cross Default. There shall occur an Event of Default as defined in
     the 2001 Senior Credit Agreement to the extent the 2001 Senior Credit
     Agreement has not been terminated, or an Event of Default as defined in the
     2002 Term Loan Agreement, unless the 2002 Term Loan Agreement has been
     fully repaid and the obligations thereunder satisfied (other than
     contingent obligations therein stated to survive termination).

     9.2 Acceleration; Remedies.

     Upon the occurrence and during the continuation of an Event of Default, the
Administrative Agent may or shall, upon the request and direction of the
Required Lenders, take the following actions without prejudice to the rights of
the Administrative Agent or any Lender to enforce its claims against the Credit
Parties, except as otherwise specifically provided for herein:

          (a) Termination of Commitments. Declare the Commitment terminated
     whereupon the Commitment shall be immediately terminated.

          (b) Acceleration of Loans. Declare the unpaid principal of and any
     accrued interest in respect of all Loans and any and all other Indebtedness
     or obligations of any and every kind owing by a Credit Party to any of the
     Lenders under the Credit Documents to be due whereupon the same shall be
     immediately due and payable without presentment, demand, protest or other
     notice of any kind, all of which are hereby waived by the Credit Parties.

          (c) Enforcement of Rights. To the extent permitted by law, enforce any
     and all rights and interests created and existing under the Credit
     Documents, including, without limitation, all rights and remedies against a
     Guarantor and all rights of set-off.

Notwithstanding the foregoing, if an Event of Default specified in Section
9.1(f) shall occur, then the Commitment shall automatically terminate and all
Loans, all accrued interest in respect thereof, all accrued and unpaid fees and
other indebtedness or obligations owing to the Lenders hereunder shall
immediately become due and payable without the giving of any notice or other
action by the Administrative Agent or the Lenders, which notice or other action
is expressly waived by the Credit Parties.

Notwithstanding the fact that enforcement powers reside primarily with the
Administrative Agent, each Lender has, to the extent permitted by law, a
separate right of payment and shall be considered a separate "creditor" holding
a separate "claim" within the meaning of Section 101(5) of the Bankruptcy Code
or any other insolvency statute.

     9.3 Allocation of Payments After Event of Default.

     Notwithstanding any other provisions of this Credit Agreement, after the
occurrence and during the continuation of an Event of Default, all amounts
collected or received by the


                                      -61-







Administrative Agent or any Lender on account of amounts outstanding under any
of the Credit Documents shall be paid over or delivered as follows:

          FIRST, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation reasonable Attorneys' Costs) of the
     Administrative Agent or any of the Lenders in connection with enforcing the
     rights of the Lenders under the Credit Documents, pro rata as set forth
     below;

          SECOND, to payment of any fees owed to the Administrative Agent or any
     Lender, pro rata as set forth below;

          THIRD, to the payment of all accrued interest payable to the Lenders
     hereunder, pro rata as set forth below;

          FOURTH, to the payment of the outstanding principal amount of the
     Loans, pro rata as set forth below;

          FIFTH, to all other obligations which shall have become due and
     payable under the Credit Documents and not repaid pursuant to clauses
     "FIRST" through "FOURTH" above; and

          SIXTH, to the payment of the surplus, if any, to whoever may be
     lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category; and (b) each of the Lenders shall receive an amount equal
to its pro rata share (based on the proportion that the then outstanding Loans
held by such Lender bears to the aggregate then outstanding Loans of amounts
available to be applied).

                                   SECTION 10

                                AGENCY PROVISIONS

     10.1 Appointment. Each Lender hereby irrevocably appoints, designates and
authorizes the Administrative Agent to take such action on its behalf under the
provisions of this Credit Agreement and each other Credit Document and to
exercise such powers and perform such duties as are expressly delegated to it by
the terms of this Credit Agreement or any other Credit Document, together with
such powers as are reasonably incidental thereto. Notwithstanding any provision
to the contrary contained elsewhere herein or in any other Credit Document, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, nor shall the Administrative Agent have or be deemed
to have any fiduciary or trustee relationship with any Lender or participant,
and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Credit


                                      -62-







Agreement or any other Credit Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Credit Documents 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.

     10.2 Delegation of Duties.

     The Administrative Agent may execute any of its duties under this Credit
Agreement or any other Credit Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel and other
consultants or experts concerning all matters pertaining to such duties. The
Administrative Agent shall not be responsible for the negligence or misconduct
of any agent or attorney-in-fact that it selects with reasonable care.

     10.3 Exculpatory Provisions.

     No Agent-Related Person shall (a) be liable for any action taken or omitted
to be taken by any of them under or in connection with this Credit Agreement or
any other Credit Document or the transactions contemplated hereby (except for
its own gross negligence or willful misconduct in connection with its duties
expressly set forth herein), or (b) be responsible in any manner to any Lender
or participant for any recital, statement, representation or warranty made by
any Credit Party or any officer thereof, contained herein or in any other Credit
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by the Administrative Agent under or in
connection with, this Credit Agreement or any other Credit Document, or the
validity, effectiveness, genuineness, enforceability or sufficiency of this
Credit Agreement or any other Credit Document, or for any failure of any Credit
Party or any other party to any Credit Document to perform its obligations
hereunder or thereunder. No Agent-Related Person shall be under any obligation
to any Lender or participant to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this Credit
Agreement or any other Credit Document, or to inspect the properties, books or
records of any Credit Party or any Affiliate thereof.

     10.4 Reliance on Communications.

          (a) The Administrative Agent shall be entitled to rely, and shall be
     fully protected in relying, upon any writing, communication, signature,
     resolution, representation, notice, consent, certificate, affidavit,
     letter, telegram, facsimile, telex or telephone message, statement or other
     document or conversation believed by it to be genuine and correct and to
     have been signed, sent or made by the proper Person or Persons, and upon
     advice and statements of legal counsel (including counsel to any Credit
     Party), independent accountants and other experts selected by the
     Administrative Agent. The Administrative Agent may deem and treat each
     Lender as the owner of its interests hereunder for all purposes unless a
     written notice of assignment, negotiation or transfer thereof shall have
     been delivered to the Administrative Agent in accordance with


                                      -63-







     Section 11.3(b). The Administrative Agent shall be fully justified in
     failing or refusing to take any action under any Credit Document unless it
     shall first receive such advice or concurrence of the Required Lenders as
     it deems appropriate and, if it so requests, 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. The Administrative Agent shall in all cases be fully
     protected in acting, or in refraining from acting, under this Credit
     Agreement or any other Credit Document in accordance with a request or
     consent of the Required Lenders or all the Lenders, if required hereunder,
     and such request and any action taken or failure to act pursuant thereto
     shall be binding upon all the Lenders and participants, and their
     respective successors and assigns. Where this Credit Agreement expressly
     permits or prohibits an action unless the Required Lenders otherwise
     determine, the Administrative Agent shall, and in all other instances, the
     Administrative Agent may, but shall not be required to, initiate any
     solicitation for the consent or a vote of the Lenders.

          (b) For purposes of determining compliance with the conditions
     specified in Section 5.1, each Lender that has signed this Credit Agreement
     shall be deemed to have consented to, approved or accepted or to be
     satisfied with, each document or other matter either sent by the
     Administrative Agent to such Lender for consent, approval, acceptance or
     satisfaction, or required thereunder to be consented to or approved by or
     acceptable or satisfactory to a Lender.

     10.5 Notice of Default.

     The Administrative Agent shall not be deemed to have knowledge or notice of
the occurrence of any Default or Event of Default, except with respect to
defaults in the payment of principal, interest and fees required to be paid to
the Administrative Agent for the account of the Lenders, unless the
Administrative Agent shall have received written notice from a Lender or the
Borrower referring to this Credit Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be reasonably directed by the Required Lenders in
accordance with Section 9.2; provided, however, that unless and until the
Administrative Agent has received any such direction, the Administrative Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default or Event of Default as it shall deem
advisable or in the best interest of the Lenders.

     10.6 Non-Reliance on Administrative Agent and Other Lenders.

     Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereinafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Credit Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related Person or any


                                      -64-







other Lender and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
prospects, operations, Property, financial and other condition and
creditworthiness of the Credit Parties and their respective Affiliates, and all
applicable bank or other regulatory laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Credit
Agreement and to extend credit to the Borrower hereunder. Each Lender also
represents that it will, independently and without reliance upon any
Agent-Related Person or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Credit Agreement and the other Credit Documents, and to make such
investigations as it deems necessary to inform itself as to the business,
prospects, operations, Property, financial and other condition and
creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent herein, the Administrative Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, Property, financial and other
condition or creditworthiness of any of the Credit Parties or any of their
respective Affiliates which may come into the possession of any Agent-Related
Person.

     10.7 Indemnification.

     Whether or not the transactions contemplated hereby are consummated, the
Lenders shall indemnify upon demand each Agent-Related Person (to the extent not
reimbursed by or on behalf of any Credit Party and without limiting the
obligation of any Credit Party to do so), pro rata, and hold harmless each
Agent-Related Person from and against any and all Indemnified Liabilities
incurred by it; provided, however, that no Lender shall be liable for the
payment to any Agent-Related Person of any portion of such Indemnified
Liabilities resulting from such Agent-Related Person's gross negligence or
willful misconduct; it being understood that no action taken in accordance with
the directions of the Required Lenders shall be deemed to constitute gross
negligence or willful misconduct for purposes of this Section 10.7. Without
limitation of the foregoing, each Lender shall reimburse the Administrative
Agent upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs) incurred by the Administrative Agent in connection
with the preparation, execution, delivery, administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Credit Agreement, any other Credit Document, or any document contemplated
by or referred to herein, to the extent that the Administrative Agent is not
reimbursed for such expenses by or on behalf of the Credit Parties. The
undertaking in this Section 10.7 shall survive termination of the Commitments,
the payment of all Obligations hereunder and the resignation or replacement of
the Administrative Agent.

     10.8 Administrative Agent in Its Individual Capacity.

     Sumitomo Mitsui Banking Corporation ("SMBC") may make loans to, issue
letters of credit for the account of, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial
advisory, underwriting or other business with each of the Credit Parties and
their respective Affiliates as though SMBC were not the Administrative Agent


                                      -65-







hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, SMBC or its Affiliates may
receive information regarding any Credit Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Credit Party or such Affiliate) and that the Administrative Agent shall be under
no obligation to provide such information to them. With respect to its Loan,
SMBC shall have the same rights and powers under this Credit Agreement as any
other Lender and may exercise such rights and powers as though it were not the
Administrative Agent, and the terms "Lender" and "Lenders" include SMBC in its
individual capacity.

     10.9 Successor Agent.

     The Administrative Agent may resign as Administrative Agent upon 30 days'
notice to the Lenders. If the Administrative Agent resigns under this Credit
Agreement, the Required Lenders shall appoint from among the Lenders a successor
administrative agent for the Lenders which successor administrative agent (such
appointment, absent the existence of an Event of Default, to be subject to the
consent of the Borrower, which consent of the Borrower shall not be unreasonably
withheld or delayed). If no successor administrative agent is appointed prior to
the effective date of the resignation of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Lenders and the
Borrower, a successor administrative agent from among the Lenders. Upon the
acceptance of its appointment as successor administrative agent hereunder, such
successor administrative agent shall succeed to all the rights, powers and
duties of the retiring Administrative Agent and the term "Administrative Agent"
shall mean such successor administrative agent and the retiring Administrative
Agent's appointment, powers and duties as Administrative Agent shall be
terminated. After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Section 10 and Sections 11.5 and
11.10 shall continue to inure to its benefit as to any actions taken or omitted
to be taken by it while it was Administrative Agent under this Credit Agreement.
If no successor administrative agent has accepted appointment as Administrative
Agent by the date which is 30 days following a retiring Administrative Agent's
notice of resignation, the retiring Administrative Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the
duties of the Administrative Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above.

                                   SECTION 11

                                  MISCELLANEOUS

     11.1 Notices.

postage prepaid, in each case to the respective


                                      -66-







parties at the address or telecopy numbers set forth on Schedule 11.1, or at
such other address as such party may specify by written notice to the other
parties hereto.

     11.2 Right of Set-Off.

          In addition to any rights now or hereafter granted under applicable
     law or otherwise, and not by way of limitation of any such rights, upon the
     occurrence of an Event of Default and the commencement of remedies
     described in Section 9.2, each Lender is authorized at any time and from
     time to time, without presentment, demand, protest or other notice of any
     kind (all of which rights being hereby expressly waived), to set-off and to
     appropriate and apply any and all deposits (general or special) and any
     other indebtedness at any time held or owing by such Lender (including,
     without limitation, branches, agencies or Affiliates of such Lender
     wherever located) to or for the credit or the account of any Credit Party
     against obligations and liabilities of such Credit Party to the Lenders
     hereunder, under the Notes, the other Credit Documents or otherwise,
     irrespective of whether the Administrative Agent or the Lenders shall have
     made any demand hereunder and although such obligations, liabilities or
     claims, or any of them, may be contingent or unmatured, and any such
     set-off shall be deemed to have been made immediately upon the occurrence
     of an Event of Default even though such charge is made or entered on the
     books of such Lender subsequent thereto. The Credit Parties hereby agree
     that any Person purchasing a participation in the Loans and Commitments
     hereunder pursuant to Sections 11.3(e) or 3.8 may exercise all rights of
     set-off with respect to its participation interest as fully as if such
     Person were a Lender hereunder.

     11.3 Benefit of Agreement.

          (a) Generally. This Credit Agreement shall be binding upon and inure
     to the benefit of and be enforceable by the respective successors and
     assigns of the parties hereto; provided that none of the Credit Parties may
     assign and transfer any of its interests (except as permitted by Section
     8.4 or 8.5) without the prior written consent of the Lenders; and provided
     further that the rights of each Lender to transfer, assign or grant
     participations in its rights and/or obligations hereunder shall be limited
     as set forth below in this Section 11.3.

          (b) Assignments. Each Lender may assign to one or more Eligible
     Assignees all or a portion of its rights and obligations under this Credit
     Agreement (including, without limitation, all or a portion of its Loans,
     its Notes and its Commitments); provided, however, that:

               (i) each such assignment shall be to an Eligible Assignee;

               (ii) except (A) in the case of an assignment to another Lender,
          (B) in the case of an assignment of all of a Lender's rights and
          obligations under this Credit Agreement, or (C) with the consent of
          the Administrative Agent and the Borrower, any such partial assignment
          shall be in an amount at least equal to $5,000,000 (or, if less, the
          remaining amount of the outstanding Term Loan, of such assigning
          Lender) or an integral multiple of $500,000 in excess thereof;


                                      -67-







               (iii) each such assignment by a Lender shall be of a constant,
          and not varying, percentage of all of its rights and obligations under
          this Credit Agreement and the Notes; and

               (iv) the parties to such assignment shall execute and deliver to
          the Administrative Agent for its acceptance an Assignment Agreement in
          substantially the form of Exhibit 11.3(b), together with a processing
          fee from the assignor of $3,500.

     Upon execution, delivery, and acceptance of such Assignment Agreement, the
     assignee thereunder shall be a party hereto and, to the extent of such
     assignment, have the obligations, rights, and benefits of a Lender
     hereunder and the assigning Lender shall, to the extent of such assignment,
     relinquish its rights and be released from its obligations under this
     Credit Agreement. Upon the consummation of any assignment pursuant to this
     Section 11.3(b), the assignor, the Administrative Agent and the Borrower
     shall make appropriate arrangements so that, if required or requested, new
     Notes are issued to the assignor and the assignee. If the assignee is a
     foreign corporation, foreign partnership or foreign trust within the
     meaning of the Code, it shall deliver to the Borrower and the
     Administrative Agent certification as to exemption from deduction or
     withholding of taxes in accordance with Section 3.13.

     By executing and delivering an assignment agreement in accordance with this
     Section 11.3(b), the assigning Lender thereunder and the assignee
     thereunder shall be deemed to confirm to and agree with each other and the
     other parties hereto as follows: (A) such assigning Lender warrants that it
     is the legal and beneficial owner of the interest being assigned thereby
     free and clear of any adverse claim and the assignee warrants that it is an
     Eligible Assignee; (B) except as set forth in clause (A) above, such
     assigning Lender makes no representation or warranty and assumes no
     responsibility with respect to any statements, warranties or
     representations made in or in connection with this Credit Agreement, any of
     the other Credit Documents or any other instrument or document furnished
     pursuant hereto or thereto, or the execution, legality, validity,
     enforceability, genuineness, sufficiency or value of this Credit Agreement,
     any of the other Credit Documents or any other instrument or document
     furnished pursuant hereto or thereto or the financial condition of any
     Credit Party or the performance or observance by any Credit Party of any of
     its obligations under this Credit Agreement, any of the other Credit
     Documents or any other instrument or document furnished pursuant hereto or
     thereto; (C) such assignee represents and warrants that it is legally
     authorized to enter into such assignment agreement; (D) such assignee
     confirms that it has received a copy of this Credit Agreement, the other
     Credit Documents and such other documents and information as it has deemed
     appropriate to make its own credit analysis and decision to enter into such
     assignment agreement; (E) such assignee will independently and without
     reliance upon the Administrative Agent, such assigning Lender or any other
     Lender, and based on such documents and information as it shall deem
     appropriate at the time, continue to make its own credit decisions in
     taking or not taking action under this Credit Agreement and the other
     Credit Documents; (F) such assignee appoints and authorizes the
     Administrative Agent to take such action on its behalf and to


                                      -68-







     exercise such powers under this Credit Agreement or any other Credit
     Document as are delegated to the Administrative Agent by the terms hereof
     or thereof, together with such powers as are reasonably incidental thereto;
     and (G) such assignee agrees that it will perform in accordance with their
     terms all the obligations which by the terms of this Credit Agreement and
     the other Credit Documents are required to be performed by it as a Lender.

          (c) Register. The Administrative Agent shall maintain a copy of each
     Assignment Agreement delivered to and accepted by it and a register for the
     recordation of the names and addresses of the Lenders and the Commitment
     of, and principal amount of the Loans owing to, each Lender from time to
     time (the "Register"). The entries in the Register shall be conclusive and
     binding for all purposes, absent manifest error, and the Borrower, the
     Administrative Agent and the Lenders may treat each Person whose name is
     recorded in the Register as a Lender hereunder for all purposes of this
     Credit Agreement. The Register shall be available for inspection by the
     Borrower or any Lender at any reasonable time and from time to time upon
     reasonable prior notice.

          (d) Acceptance. Upon its receipt of an Assignment Agreement executed
     by the parties thereto, together with any Note subject to such assignment
     and payment of the processing fee, the Administrative Agent shall, if such
     Assignment Agreement has been completed and is in substantially the form of
     Exhibit 11.3(b), (i) accept such Assignment Agreement, (ii) record the
     information contained therein in the Register and (iii) give prompt notice
     thereof to the parties thereto.

          (e) Participations. Each Lender may sell participations to one or more
     Persons in all or a portion of its rights, obligations or rights and
     obligations under this Credit Agreement (including all or a portion of its
     Commitment and its Loans); provided, however, that (i) such Lender's
     obligations under this Credit Agreement shall remain unchanged, (ii) such
     Lender shall remain solely responsible to the other parties hereto for the
     performance of such obligations, (iii) the participant shall be entitled to
     the benefit of the yield protection provisions contained in Sections 3.9
     through 3.15, inclusive (but not for a greater amount than the Lender would
     be entitled to), and of the right of set-off contained in Section 11.2,
     (iv) the Borrower shall continue to deal solely and directly with such
     Lender in connection with such Lender's rights and obligations under this
     Credit Agreement, and (v) such Lender shall retain the sole right to
     enforce the obligations of the Borrower relating to its Loans and its Notes
     and to approve any amendment, modification, or waiver of any provision of
     this Credit Agreement (other than amendments, modifications, or waivers
     decreasing the amount of principal of or the rate at which interest is
     payable on such Loans or Notes, extending any scheduled principal payment
     date or date fixed for the payment of interest on such Loans or Notes,
     extending its Commitment or releasing the Borrower or all or substantially
     all of the Guarantors from its or their respective obligations under the
     Credit Documents).

          (f) Unrestricted Assignments. Notwithstanding any other provision set
     forth in this Credit Agreement, any Lender may at any time (i) assign and
     pledge all or any portion of its Loans and its Notes to any Federal Reserve
     Bank as collateral security pursuant to Regulation A and any Operating
     Circular issued by such Federal Reserve


                                      -69-







     Bank or (ii) pledge all or any portion of its rights (but not its
     obligations to make Loans hereunder to any trustee or holders of
     obligations owed, or securities issued, by such Lender as security for such
     obligations or securities or to any other representative of such holders;
     provided that such trustee or holder shall not have the right to become a
     Lender hereunder. No such assignment shall release the assigning Lender
     from its obligations hereunder.

          (g) Information. Any Lender may furnish any information concerning the
     Borrower or any of its Subsidiaries in the possession of such Lender from
     time to time to assignees and participants (including prospective assignees
     and participants), subject, however, to the provisions of Section 11.15.

          (h) CLO's. Notwithstanding anything to the contrary contained herein,
     any Lender, (a "Granting Lender") may grant to a special purpose funding
     vehicle (an "SPC") the option to fund all or any part of any Loan that such
     Granting Lender would otherwise be obligated to fund pursuant to this
     Credit Agreement; provided that (i) nothing herein shall constitute a
     commitment by any SPC to fund any Loan, (ii) if an SPC elects not to
     exercise such option or otherwise fails to fund all or any part of such
     Loan, the Granting Lender shall be obligated to fund such Loan pursuant to
     the terms hereof, (iii) no SPC shall have any voting rights pursuant to
     Section 11.6 and (iv) with respect to notices, payments and other matters
     hereunder, the Credit Parties, the Administrative Agent and the Lenders
     shall not be obligated to deal with an SPC, but may limit their
     communications and other dealings relevant to such SPC to the applicable
     Granting Lender. The funding of a Loan by an SPC hereunder shall utilize
     the Loan Commitment of the Granting Lender to the same extent that, and as
     if, such Loan were funded by such Granting Lender. Each party hereto hereby
     agrees that no SPC shall be liable for any indemnity or payment under this
     Credit Agreement for which a Lender would otherwise be liable for so long
     as, and to the extent, the Granting Lender provides such indemnity or makes
     such payment. Notwithstanding anything to the contrary contained in this
     Credit Agreement, any SPC may disclose on a confidential basis any
     non-public information relating to its funding of Loans to any rating
     agency, commercial paper dealer or provider of any surety or guarantee to
     such SPC. This clause (h) may not be amended without the prior written
     consent of each Granting Lender, all or any part of whose Loan is being
     funded by an SPC at the time of such amendment.

     11.4 No Waiver; Remedies Cumulative.

     No failure or delay on the part of the Administrative Agent or any Lender
in exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Borrower or any Credit Party and
the Administrative Agent or any Lender shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
or under any other Credit Document preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder or
thereunder. The rights and remedies provided herein are cumulative and not
exclusive of any rights or remedies which the Administrative Agent or any Lender
would otherwise have. No notice to or demand on any Credit Party in any case
shall entitle any Credit Party to any other or further notice or demand in
similar or


                                      -70-







other circumstances or constitute a waiver of the rights of the Administrative
Agent or the Lenders to any other or further action in any circumstances without
notice or demand.

     11.5 Payment of Expenses; Indemnification.

     The Borrower agrees to: (a) pay all reasonable out-of-pocket costs and
expenses of the Administrative Agent and the Lenders in connection with (A)
enforcement of the Credit Documents and the documents and instruments referred
to therein, including, without limitation, in connection with any such
enforcement, the reasonable Attorneys' Costs of the Administrative Agent and
each of the Lenders and (B) any bankruptcy or insolvency proceeding of any
Credit Party, and (b) indemnify the Administrative Agent and each Lender, its
officers, directors, employees, representatives, counsel and agents from and
hold each of them harmless against any and all losses, liabilities, claims,
damages or expenses incurred by any of them as a result of, or arising out of,
or in any way related to, or by reason of, any investigation, litigation or
other proceeding (whether or not the Administrative Agent or any Lender is a
party thereto) related to the entering into and/or performance of any Credit
Document or the use of proceeds of any Loans (including other extensions of
credit) hereunder or the consummation of any other transactions contemplated in
any Credit Document, including, without limitation, reasonable Attorneys' Costs
incurred in connection with any such investigation, litigation or other
proceeding (but excluding any such losses, liabilities, claims, damages or
expenses to the extent incurred by reason of gross negligence or willful
misconduct on the part of the Person to be indemnified), (all of the foregoing,
collectively, "Indemnified Liabilities"). The agreements in this Section 11.5
shall survive the termination of the Commitments and the repayment of the Credit
Party Obligations.

     11.6 Amendments, Waivers and Consents.

     So long as the Initial Lender is the sole Lender under this Agreement and
is party to the 2001 Senior Credit Agreement, any amendment to the covenants of
the 2001 Senior Credit Agreement adopted in accordance with the terms thereof
and to which the Initial Lender shall have consented in its capacity as party to
the 2001 Senior Credit Agreement, shall represent the Initial Lender's consent
to amend this Agreement in a corresponding manner. It is agreed that, if lenders
party to the 2001 Senior Credit Agreement receive any fee in connection with any
such amendment, the Initial Lender shall receive a fee with respect to the
foregoing amendment of this Agreement, which shall be calculated in the same
manner as the fees received by the lenders parties to the 2001 Senior Credit
Agreement in connection with such amendment. If the Initial Lender participates
as a lender in a facility that replaces the 2001 Senior Credit Agreement (a
"Replacement Facility"), such participation shall represent its agreement to
amend this Agreement to conform to the covenants of such Replacement Facility,
and the Initial Lender agrees that it shall not be entitled to fees commensurate
with those paid to lenders in the Replacement Facility in connection with such
conforming amendment to this facility. The Initial Lender (or the Administrative
Agent if the Initial Lender is not the sole Lender under this facility) agrees
to use its best efforts to limit the cost to the Borrower of documenting any and
all amendments hereto, including the use of its internal legal counsel to
prepare documentation when feasible. In all other cases, neither this Credit
Agreement nor any other Credit Document nor any of the terms hereof or thereof
may be amended, changed, waived, discharged or terminated unless such amendment,
change, waiver, discharge or termination is in writing and signed by the
Required Lenders and the then Credit Parties; provided that no such


                                      -71-







amendment, change, waiver, discharge or termination shall without the consent of
each Lender affected thereby:

          (a) extend the Maturity Date or extend or postpone the time for any
     payment or prepayment of principal;

          (b) reduce the rate or extend the time of payment of interest (other
     than as a result of waiving the applicability of any post-default increase
     in interest rates) thereon or fees hereunder;

          (c) reduce or waive the principal amount of any Loan;

          (d) increase or extend the Commitment of a Lender (it being understood
     and agreed that a waiver of any Default or Event of Default shall not
     constitute a change in the terms of any Commitment of any Lender);

          (e) release the Borrower from its obligations or consent to the
     assignment or transfer by the Borrower of any of its rights and obligations
     under (or in respect of) the Credit Documents or release all or
     substantially all of the Guarantors from their respective obligations under
     the Credit Documents;

          (f) amend, modify or waive any provision of this Section 11.6 or
     Sections 3.7, 3.8, 5.2, 9.1(a), 11.2, 11.3 or 11.5; or

          (g) reduce any percentage specified in, or otherwise modify, the
     definition of Required Lenders.

Notwithstanding the above, no provisions of Section 10 or Section 3.4 may be
amended or modified without the consent of the Administrative Agent.

Notwithstanding the fact that the consent of all the Lenders is required in
certain circumstances as set forth above, (x) each Lender is entitled to vote as
such Lender sees fit on any reorganization plan that affects the Loans and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy
Code supersedes the unanimous consent provisions set forth herein and (y) the
Required Lenders may consent to allow a Credit Party to use cash collateral in
the context of a bankruptcy or insolvency proceeding.

     11.7 Counterparts/Telecopy.

     This Credit Agreement may be executed in any number of counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall constitute one and the same instrument. Delivery of executed counterparts
by telecopy shall be as effective as an original and shall constitute a
representation that an original will be delivered.


                                      -72-







     11.8 Headings.

     The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

     11.9 Defaulting Lender.

     Each Lender understands and agrees that if such Lender is a Defaulting
Lender then notwithstanding the provisions of Section 11.6 it shall not be
entitled to vote on any matter requiring the consent of the Required Lenders or
to object to any matter requiring the consent of all the Lenders; provided,
however, that all other benefits and obligations under the Credit Documents
shall apply to such Defaulting Lender.

     11.10 Survival of Indemnification.

     All indemnities set forth herein shall survive the execution and delivery
of this Credit Agreement, the making of the Loans, the repayment of the Loans
and other obligations and the termination of the Commitments hereunder.

     11.11 Governing Law; Venue; Jurisdiction.

          (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE
     RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE
     GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF
     THE STATE OF NEW YORK. Any legal action or proceeding with respect to this
     Credit Agreement or any other Credit Document may be brought in the courts
     of the State of New York or of the United States sitting in New York City,
     and, by execution and delivery of this Credit Agreement, each Credit Party
     hereby irrevocably accepts for itself and in respect of its Property,
     generally and unconditionally, the jurisdiction of such courts. Each Credit
     Party irrevocably consents to the service of process in any action or
     proceeding with respect to this Credit Agreement or any other Credit
     Document by the mailing of copies thereof by registered or certified mail,
     postage prepaid, to it at the address for notices pursuant to Section 11.1,
     such service to become effective 10 days after such mailing. Nothing herein
     shall affect the right of a Lender to serve process in any other manner
     permitted by law or to commence legal proceedings or otherwise proceed
     against a Credit Party in any other jurisdiction. Each Credit Party agrees
     that a final judgment in any action or proceeding shall be conclusive and
     may be enforced in other jurisdictions by suit on the judgment or in any
     other manner provided by law; provided that nothing in this Section
     11.11(a) is intended to impair a Credit Party's right under applicable law
     to appeal or seek a stay of any judgment.

          (b) Each Credit Party hereby irrevocably waives any objection which it
     may now or hereafter have to the laying of venue of any of the aforesaid
     actions or proceedings arising out of or in connection with this Credit
     Agreement or any other Credit Document in the courts referred to in
     subsection (a) hereof and hereby further irrevocably waives and


                                      -73-







     agrees not to plead or claim in any such court that any such action or
     proceeding brought in any such court has been brought in an inconvenient
     forum.

     11.12 Waiver of Jury Trial; Waiver of Consequential Damages.

     EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES ALL
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF
OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR THE
TRANSACTIONS CONTEMPLATED HEREBY. Each Credit Party agrees not to assert any
claim against the Administrative Agent, any Lender, any of their Affiliates, or
any of their respective directors, officers, employees, attorneys or agents, on
any theory of liability, for special, indirect, consequential or punitive
damages arising out of or otherwise relating to any of the transactions
contemplated herein.

     11.13 Severability.

     If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

     11.14 Further Assurances.

     The Credit Parties agree, upon the request of the Administrative Agent, to
promptly take such actions, as reasonably requested, as is necessary to carry
out the intent of this Credit Agreement and the other Credit Documents.

     11.15 Confidentiality.

     Each Lender agrees that it will use its reasonable best efforts to keep
confidential and to cause any representative designated under Section 7.11 to
keep confidential any non-public information from time to time supplied to it
under any Credit Document; provided, however, that nothing herein shall prevent
the disclosure of any such information to (a) the extent a Lender in good faith
believes such disclosure is required by Requirement of Law, (b) counsel for a
Lender or to its accountants, (c) bank examiners or auditors or comparable
Persons, (d) any Affiliate of a Lender, (e) any other Lender, or any assignee,
transferee or participant, or any potential assignee, transferee or participant,
of all or any portion of any Lender's rights under this Credit Agreement who is
notified of the confidential nature of the information or (f) any other Person
in connection with any litigation to which any one or more of the Lenders is a
party if required by a court of law of competent jurisdiction or (g) that a
Lender may disclose (without limitation) the tax treatment and tax structure of
this financing and any materials provided to any Lender relating to such tax
treatment or tax structure. No Lender shall have any obligation under this
Section 11.15 to the extent any such information becomes available on a
non-confidential basis from a source other than a Credit Party or that any
information becomes publicly available other than by a breach of this Section
11.15 by any Lender or representative thereof.


                                      -74-







     11.16 Entirety.

     This Credit Agreement together with the other Credit Documents represents
the entire agreement of the parties hereto and thereto, and supersede all prior
agreements and understandings, oral or written, if any, including any commitment
letters or correspondence relating to the Credit Documents or the transactions
contemplated herein and therein.

     11.17 Binding Effect; Continuing Agreement.

          (a) This Credit Agreement shall become effective at such time when all
     of the conditions set forth in Section 5.1 have been satisfied or waived by
     the Lenders and it shall have been executed by the Borrower, the Guarantors
     and the Administrative Agent, and the Administrative Agent shall have
     received copies hereof (telefaxed or otherwise) which, when taken together,
     bear the signatures of each Lender, and thereafter this Credit Agreement
     shall be binding upon and inure to the benefit of the Borrower, the
     Guarantors, the Administrative Agent and each Lender and their respective
     successors and assigns.

          (b) This Credit Agreement shall be a continuing agreement and shall
     remain in full force and effect until all Loans, interest, fees and other
     Credit Party Obligations have been paid in full and the Commitments have
     been terminated. Upon termination, the Credit Parties shall have no further
     obligations (other than the indemnification provisions that survive) under
     the Credit Documents; provided that should any payment, in whole or in
     part, of the Credit Party Obligations be rescinded or otherwise required to
     be restored or returned by the Administrative Agent or any Lender, whether
     as a result of any proceedings in bankruptcy or reorganization or
     otherwise, then the Credit Documents shall automatically be reinstated and
     all amounts required to be restored or returned and all costs and expenses
     incurred by the Administrative Agent or any Lender in connection therewith
     shall be deemed included as part of the Credit Party Obligations.


                                      -75-







     Each of the parties hereto has caused a counterpart of this Credit
Agreement to be duly executed and delivered as of the date first above written.
