      necessary, to an integral multiple of $1,000,000) equal to the then
      outstanding principal amount of the Senior Notes as of such effectiveness
      plus all make-whole amounts that would have been paid on such Senior Notes
      if they had been prepaid on the date of such effectiveness.

            (e)   Once reduced in accordance with this Section, the Aggregate
      Commitment may not be increased. Any reduction of the Aggregate Commitment
      shall be applied to reduce the amount of the Commitment of each Bank
      according to its Pro Rata Share. All accrued commitment fees to the
      effective date of any reduction or termination of the Aggregate Commitment
      shall be paid on the effective date of such reduction or termination.

      2.6   Prepayments.

            (a)   The Borrower may, at any time or from time to time, upon not
      less than one Business Day's irrevocable notice to the Agent, ratably
      prepay Loans in whole or in part, in a minimum amount of $5,000,000 or any
      higher integral multiple of $1,000,000. Such notice of prepayment shall
      specify the date and amount of such prepayment and the Type(s) of Advances
      to be prepaid. If such notice is given by the Borrower, the payment amount
      specified in such notice shall be due and payable on the date specified
      therein.

            (b)   Concurrently with the receipt by the Borrower of any Net Cash
      Proceeds, the Borrower shall make a prepayment of the Loans in an amount
      (the "Proceeds Application Amount") equal to the remainder (rounded down,
      if necessary, to an integral multiple of $1,000,000) of (i) all Net Cash
      Proceeds received since the date hereof minus (ii) the sum of (x) the
      aggregate amount of such Net Cash Proceeds previously applied to prepay
      Loans pursuant to this Section 2.6(b) plus (y) the aggregate amount of Net
      Cash Proceeds previously applied to reduce the Aggregate Commitment
      pursuant to Section

                                       24
<PAGE>

      2.5(c) (and, if all outstanding Loans have been paid in full, the
      remainder of the Proceeds Application Amount shall be applied in
      accordance with Section 2.5(c)); provided that, unless an Event of Default
      has occurred and is continuing, if and to the extent that any prepayment
      required by the foregoing would result in an obligation of the Borrower to
      pay any amount pursuant to Section 3.4, the Borrower may, upon notice to
      the Agent, deposit the amount of such required prepayment in an escrow
      account on terms satisfactory to the Agent to be applied to the prepayment
      of the Loans on the last day of each Interest Period ending thereafter
      until such prepayment has been made in full (or on such earlier date as
      the Loans become payable in accordance with the terms hereof).

            (c)   The Agent will promptly notify each Bank (i) of its receipt of
      any notice of prepayment pursuant to clause (a) above and (ii) upon
      receipt of notice of any mandatory prepayment pursuant to clause (b)
      above. All prepayments shall be applied ratably to the Loans of the Banks
      in accordance with their respective Pro Rata Shares and to such Advances
      as the Borrower shall specify. Concurrently with any prepayment, the
      Borrower shall pay accrued interest on the amount prepaid and all amounts
      required pursuant to Section 3.4.

            (d)   The Borrower shall have no right to reborrow any portion of a
      Loan which has been prepaid.

      2.7   Repayment. The Borrower shall repay all outstanding Loans on the
Maturity Date.

      2.8   Interest. (a) Each Advance shall bear interest on the outstanding
principal amount thereof from the applicable Drawdown Date at a rate per annum
equal to the Offshore Rate or the Federal Funds Rate, as the case may be (and
subject to the Borrower's right to convert to the other Type of Advance under
Section 2.4), plus the Applicable Margin.

            (b)   Interest on each Advance shall be paid in arrears on each
      Interest Payment Date and on the date of any prepayment thereof (as
      provided in Section 2.6(c)). During the existence of any Event of Default,
      interest shall be paid on demand of the Agent at the request or with the
      consent of the Majority Banks.

            (c)   The Pricing Level in effect on the date hereof shall be
      Pricing Level II. Any change in the Applicable Margin or the Applicable
      Facility Fee Rate resulting from a change in the Pricing Level in
      accordance with the Pricing Grid shall be effective on the tenth day after
      the earlier of (i) the delivery of the certificate required pursuant to
      Section 6.1(c) or (ii) the date by which the delivery of such certificate
      is required under Section 6.1(c), based on the Leverage Ratio as of the
      last day of the applicable fiscal quarter or fiscal year; it being
      understood that if the Borrower fails to deliver the financial statements
      or certificate required by Section 6.1(c) by the required delivery date
      for any fiscal quarter or fiscal year, commencing on such required
      delivery date, until the date such financial statements or certificate are
      delivered, the Pricing Level in effect shall be Pricing Level III.

                                       25
<PAGE>

            (d)   Notwithstanding clause (a) above, while any Event of Default
      exists or after acceleration, the Borrower shall pay interest (after as
      well as before entry of judgment thereon to the extent permitted by law)
      on the principal amount of all outstanding Advances, at a rate per annum
      which is determined by adding 2% per annum to the rate of interest then in
      effect for such Advances; provided that, on and after the expiration of
      any Interest Period applicable to any Borrowing of Offshore Rate Advances
      outstanding on the date of occurrence of such Event of Default or
      acceleration, the principal amount of such Advances shall, during the
      continuation of such Event of Default or after acceleration, bear interest
      at a rate per annum equal to the Federal Funds Rate plus 2%.

            (e)   Anything herein to the contrary notwithstanding, the
      obligations of the Borrower to any Bank hereunder shall be subject to the
      limitation that payments of interest shall not be required for any period
      for which interest is computed hereunder, to the extent (but only to the
      extent) that contracting for or receiving such payment by such Bank would
      be contrary to the provisions of any law applicable to such Bank limiting
      the highest rate of interest that may be lawfully contracted for, charged
      or received by such Bank, and in such event the Borrower shall pay such
      Bank interest at the highest rate permitted by applicable law.

      2.9   Fees. (a) Arrangement, Agency Fees. The Borrower shall pay certain
fees to the Arranger and the Agent as provided in the letter agreement (the "Fee
Letter") dated March 25, 2005 among the Borrower, the Arranger and the Agent.

            (b)   Facility Fees. The Borrower agrees to pay to the Agent for the
      account of each Bank a facility fee on the average daily amount of the sum
      of (i) the amount of such Bank's Commitment (as reduced from time to time)
      plus (ii) the principal amount of such Bank's outstanding Loan, computed
      on a quarterly basis in arrears on the last Business Day of each calendar
      quarter for that quarter as calculated by the Agent, equal to the
      Applicable Facility Fee Rate per annum. Such facility fee shall accrue at
      all times after the earlier to occur of (i) the satisfaction (or waiver by
      the Majority Banks at the request of the Borrower) of each condition
      precedent set forth in Article IV and (ii) April 11, 2005 to the date on
      which the Aggregate Commitment is reduced to zero or the Commitments are
      otherwise terminated and shall be due and payable quarterly in arrears on
      the last Business Day of each calendar quarter, commencing on June 30,
      2005, and on the Maturity Date (and, if applicable, thereafter on demand);
      provided that, in connection with any reduction or termination of the
      Commitments under Section 2.5, the accrued facility fee calculated for the
      period ending on such date shall also be paid on the date of such
      reduction or termination, with the following quarterly payment being
      calculated on the basis of the period from such reduction or termination
      date to such quarterly payment date. If the Loans and facility fees are
      not paid on the Maturity Date, facility fees shall accrue after the
      Maturity Date on the amount of outstanding Loans (as opposed to
      Commitments) and shall be paid concurrently with the repayment of the
      Loans.

      2.10  Computation of Fees and Interest. (a) All computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed
(which results in more interest being paid than if computed on the basis of a
365-day year). Interest and fees shall accrue during

                                       26
<PAGE>

each period during which interest or such fees are computed from the first day
thereof to the last day thereof.

            (b)   Each determination of an interest rate by the Agent shall be
      conclusive and binding on the Borrower and the Banks in the absence of
      manifest error. The Agent will, at the request of the Borrower or any
      Bank, deliver to the Borrower or such Bank, as the case may be, a
      statement showing the quotations used by the Agent in determining any
      interest rate and the resulting interest rate.

      2.11  Payments by the Borrower. (a) All payments to be made by the
Borrower shall be made without set-off, recoupment or counterclaim. Except as
otherwise expressly provided herein, all payments by the Borrower shall be made
to the Agent for the account of the Banks at the Agent's Payment Office, and
shall be made in dollars and in immediately available funds, no later than 3:00
p.m. on the date specified herein. The Agent will promptly distribute to each
Bank its Pro Rata Share (or other applicable share as expressly provided herein)
of such payment in like funds as received. Any payment received by the Agent
later than 3:00 p.m. shall be deemed to have been received on the following
Business Day and any applicable interest or fee shall continue to accrue.

            (b)   Subject to the provisions set forth in the definition of
      "Interest Period" herein, whenever any payment is due on a day other than
      a Business Day, such payment shall be made on the following Business Day,
      and such extension of time shall in such case be included in the
      computation of interest or fees, as the case may be.

            (c)   Unless the Agent receives notice from the Borrower prior to
      the date on which any payment is due to the Banks that the Borrower will
      not make such payment in full as and when required, the Agent may assume
      that the Borrower has made such payment in full to the Agent on such date
      in immediately available funds and the Agent may (but shall not be so
      required), in reliance upon such assumption, distribute to each Bank on
      such due date an amount equal to the amount then due such Bank. If and to
      the extent the Borrower has not made such payment in full to the Agent,
      each Bank shall repay to the Agent on demand such amount distributed to
      such Bank, together with interest thereon at the Federal Funds Rate for
      each day from the date such amount is distributed to such Bank until the
      date repaid. A notice of the Agent to any Bank with respect to any amount
      owing under this clause (c) shall be conclusive absent manifest error.

      2.12  Payments by the Banks to the Agent. (a) Unless the Agent receives
notice from a Bank on or prior to the Closing Date or, with respect to any
drawdown after the Closing Date, at least one Business Day prior to the date of
such drawdown, that such Bank will not make available as and when required
hereunder to the Agent for the account of the Borrower the amount of such Bank's
Pro Rata Share of such drawdown, the Agent may assume that such Bank has made
such amount available to the Agent in immediately available funds on the
Drawdown Date and the Agent may (but shall not be so required), in reliance upon
such assumption, make available to the Borrower on such date a corresponding
amount. If and to the extent any Bank shall not have made its full amount
available to the Agent in immediately available funds and the Agent in such
circumstances has made available to the Borrower such amount, such Bank shall

                                       27
<PAGE>

on the Business Day following such Drawdown Date make such amount available to
the Agent, together with interest at the Federal Funds Rate for each day during
such period. A notice of the Agent submitted to any Bank with respect to amounts
owing under this clause (a) shall be conclusive, absent manifest error. If such
amount is so made available, such payment to the Agent shall constitute such
Bank's Pro Rata Share of the drawdown on the Drawdown Date for all purposes of
this Agreement. If such amount is not made available to the Agent on the
Business Day following the Drawdown Date, the Agent will notify the Borrower of
such failure to fund and, upon demand by the Agent, the Borrower shall pay such
amount to the Agent for the Agent's account within two Business Days, together
with interest thereon for each day elapsed since the date of such drawdown (but
without any additional payment under Section 3.4), at a rate per annum equal to
the interest rate applicable at the time to the Advances comprising such
drawdown.

            (b)   The failure of any Bank to make available its Pro Rata Share
      of any drawdown on any Drawdown Date shall not relieve any other Bank of
      any obligation hereunder to make available its Pro Rata Share of any
      drawdown on such Drawdown Date, but no Bank shall be responsible for the
      failure of any other Bank to make available its Pro Rata Share of the
      drawdown to be made by such other Bank on any Drawdown Date.

      2.13  Sharing of Payments, Etc. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of its Loan any payment
(whether voluntary, involuntary, through the exercise of any right of set-off,
or otherwise) in excess of its Pro Rata Share, such Bank shall immediately (a)
notify the Agent of such fact, and (b) purchase from the other Banks such
participations in the Loans made by them as shall be necessary to cause such
purchasing Bank to share the excess payment pro rata with each of them; provided
that if all or any portion of such excess payment is thereafter recovered from
the purchasing Bank, such purchase shall to that extent be rescinded and each
other Bank shall repay to the purchasing Bank the purchase price paid therefor,
together with an amount equal to such paying Bank's ratable share (according to
the proportion of (i) the amount of such paying Bank's required repayment to
(ii) the total amount so recovered from the purchasing Bank) of any interest or
other amount paid or payable by the purchasing Bank in respect of the total
amount so recovered. The Borrower agrees that any Bank so purchasing a
participation from another Bank may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 9.11) with respect to such participation as fully as if such Bank
were the direct creditor of the Borrower in the amount of such participation.
The Agent will keep records (which shall be conclusive and binding in the
absence of manifest error) of participations purchased under this Section and
will in each case notify the Banks following any such purchases or repayments.
Each Bank that purchases a participation pursuant to this Section shall from and
after such purchase have the right to give all notices, requests, demands,
directions and other communications under this Agreement with respect to the
portion of the Obligations purchased to the same extent as though the purchasing
Bank were the original owner of the Obligations purchased.

                                  ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

      3.1   Taxes.

      (a)   Any and all payments by the Borrower to or for the account of the
Agent or any Bank under any Loan Document shall be made free and clear of and
without deduction for any and all present or future taxes, duties, levies,
imposts, deductions, assessments, fees, withholdings or similar charges, and all
liabilities with respect thereto, excluding, in the case of the Agent and each
Bank, taxes imposed on or measured by its overall 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 Agent or such Bank,
as the case may be, is organized or maintains a lending office (all such
non-excluded taxes, duties, levies, imposts, deductions, assessments, fees,
withholdings or similar charges, and liabilities being hereinafter referred to
as "Taxes"). If the Borrower shall be required by any law to deduct any Taxes
from or in respect of any sum payable under any Loan Document to the Agent or
any Bank, (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), each of the Agent and such Bank receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law, and (iv) within 30 days after the date of such
payment, the Borrower shall furnish to the Agent (which shall forward the same
to such Bank) the original or a certified copy of a receipt evidencing payment
thereof.

      (b)   In addition, the Borrower 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 Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "Other Taxes"). If the Borrower shall be required to deduct or
pay any Taxes or Other Taxes from or in respect of any sum payable under any
Loan Document to the Agent or any Bank, the Borrower shall also pay to the Agent
or to such Bank, as the case may be, at the time interest is paid, such
additional amount that the Agent or such Bank specifies is necessary to preserve
the after-tax yield (after factoring in all taxes in respect of such additional
amount, including taxes imposed on or measured by net income) that the Agent or
such Bank would have received if such Taxes or Other Taxes had not been imposed.

      (c)   The Borrower agrees to indemnify the Agent and each Bank 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) paid by
the Agent and such Bank, (ii) amounts payable under this Section 3.1(c) and
(iii) any liability (including additions to tax, penalties, interest and
expenses) arising therefrom or with respect thereto, in each case whether or not
such Taxes or Other Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority; provided, however, any claim under this Section
3.1 must be reasonable. Payment under this clause (c) shall be made within 30
days after the date the

                                       29
<PAGE>

applicable Bank or the Agent makes a demand therefor, stating in reasonable
detail the basis for the indemnification claim.

      3.2   Illegality. If any Bank determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for such Bank or its applicable Lending Office to maintain
tranches of its Loans as Offshore Rate Advances, then, on notice thereof by such
Bank to the Borrower through the Agent (and continuing for so long as the
circumstances giving rise to such determination exist), (a) any obligation of
such Bank to make Advances as, or convert Advances into, Offshore Rate Advances
shall be suspended, and (b) on the last day of the Interest Period for each
outstanding Offshore Rate Advance of such Bank (or on such earlier date as may
be required by any Requirement of Law), such Advance shall convert into a
Federal Funds Rate Advance. If a Bank makes a determination under this Section
3.2, then such Bank shall use reasonable efforts (consistent with legal and
regulatory restrictions) to change the jurisdiction of its Lending Office so as
to eliminate any such illegality, if such change in the judgment of such Bank is
not otherwise materially disadvantageous to such Bank.

      3.3   Increased Costs and Reduction of Return. (a) If any Bank determines
that, due to either (i) the introduction of or any change (other than any change
by way of imposition of or increase in reserve requirements included in the
calculation of the Offshore Rate) in the interpretation of any law or regulation
or (ii) the compliance by such Bank with any guideline or request from any
central bank or other Governmental Authority (whether or not having the force of
law), there shall be any increase in the cost to such Bank of agreeing to make
or making, funding or maintaining any Offshore Rate Advances, then the Borrower
shall be liable for, and shall from time to time, upon demand (with a copy of
such demand to be sent to the Agent), pay to the Agent for the account of such
Bank, additional amounts as are sufficient to compensate such Bank for such
increased costs; provided that the Borrower shall not be required to pay any
such expense if the applicable Bank shall not notify the Borrower of such
expense within 180 days of such Bank being aware of its incurrence.

            (b)   If any Bank determines that (i) the introduction of any
      Capital Adequacy Regulation, (ii) any change in any Capital Adequacy
      Regulation, (iii) any change in the interpretation or administration of
      any Capital Adequacy Regulation by any central bank or other Governmental
      Authority charged with the interpretation or administration thereof or
      (iv) compliance by such Bank (or its Lending Office) or any corporation
      controlling such Bank with any Capital Adequacy Regulation, increases or
      would increase the amount of capital required or expected to be maintained
      by such Bank or any corporation controlling such Bank (taking into
      consideration such Bank's or such corporation's policies with respect to
      capital adequacy and such Bank's desired return on capital) as a
      consequence of its Commitment, Loan, credits or obligations under this
      Agreement, then, upon demand of such Bank to the Borrower through the
      Agent, the Borrower shall pay to such Bank, from time to time as specified
      by such Bank, additional amounts sufficient to compensate such Bank for
      such increase; provided that the Borrower shall not be required to pay any
      such expense if the applicable Bank shall not notify the Borrower of such
      expense within 180 days of such Bank being aware of its incurrence.

                                       30
<PAGE>

            (c)   If the Borrower is required to pay additional amounts to any
Bank or the Agent pursuant to this Section 3.3, then such Bank shall use
reasonable efforts (consistent with legal and regulatory restrictions) to change
the jurisdiction of its Lending Office so as to eliminate any such additional
payment by the Borrower which may thereafter accrue, if such change in the
judgment of such Bank is not otherwise materially disadvantageous to such Bank.

      3.4   Funding Losses. The Borrower shall reimburse each Bank and hold each
Bank harmless from any loss or expense which such Bank may sustain or incur as a
consequence of:

            (a)   the failure of the Borrower to make on a timely basis any
      payment of principal of any Offshore Rate Advance;

            (b)   the failure of the Borrower to make a drawdown, or to continue
      or convert an Advance, after the Borrower has given (or is deemed to have
      given) a Notice of Drawdown or a Notice of Conversion/ Continuation, as
      applicable;

            (c)   the failure of the Borrower to make any prepayment in
      accordance with any notice delivered under Section 2.6; or

            (d)   the prepayment or other payment (including after acceleration
      thereof) or conversion (including pursuant to Section 3.2) of an Offshore
      Rate Advance on a day that is not the last day of the relevant Interest
      Period,

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Advances or from fees
payable to terminate the deposits from which such funds were obtained. The
Borrower shall also pay any customary administrative fees charged by such Bank
in connection with the foregoing. For purposes of calculating amounts payable by
the Borrower to the Banks under this Section and under Section 3.3(a), each
Offshore Rate Advance made by a Bank (and each related reserve, special deposit
or similar requirement) shall be conclusively deemed to have been funded at the
Offshore Base Rate used in determining the Offshore Rate for such Offshore Rate
Advance by a matching deposit or other borrowing in the interbank eurodollar
market for a comparable amount and for a comparable period, whether or not such
Offshore Rate Advance is in fact so funded.

      3.5   Inability to Determine Rates. If the Agent determines that for any
reason adequate and reasonable means do not exist for determining the Offshore
Rate for any requested Interest Period with respect to a proposed Offshore Rate
Advance, or that the Offshore Rate applicable pursuant to Section 2.8(a) for any
requested Interest Period with respect to a proposed Offshore Rate Advance does
not adequately and fairly reflect the cost to the Banks of funding such Advance,
the Agent will promptly so notify the Borrower and each Bank. Thereafter, the
obligation of the Banks to make or maintain Offshore Rate Advances hereunder
shall be suspended until the Agent revokes such notice in writing. Upon receipt
of such notice, the Borrower may revoke any Notice of Drawdown or Notice of
Conversion/Continuation then submitted by it. If the Borrower does not revoke
such Notice, the Banks shall make the drawdown, or convert or continue the
Advances, as proposed by the Borrower and in the amount specified in the
applicable notice submitted by the Borrower, but such drawdown shall be

                                       31
<PAGE>

comprised of, and such Advances shall be converted to or continued as, Federal
Funds Rate Advances.

      3.6   Certificates of Banks. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Borrower (with a copy
to the Agent) a certificate setting forth in reasonable detail the amount
payable to such Bank hereunder and such certificate shall be presumptively
correct and binding on the Borrower in the absence of manifest error.

      3.7   Substitution of Banks. Upon the receipt by the Borrower from any
Bank (an "Affected Bank") of a claim for compensation under Section 3.1 or 3.3,
or any determination of illegality under Section 3.2, the Borrower may: (a)
request the Affected Bank to use its best efforts to obtain a replacement bank
or financial institution satisfactory to the Borrower to acquire and assume all
or a ratable part of all of such Affected Bank's Loan and Commitment (a
"Replacement Bank"); (b) request one more of the other Banks to acquire and
assume all or part of such Affected Bank's Loans and Commitment or (c) designate
a Replacement Bank. Any such designation of a Replacement Bank under clause (a)
or (c) shall be subject to the prior written consent of the Agent (which consent
shall not be unreasonably withheld).

      3.8   Survival. The agreements and obligations of the Borrower in this
Article III shall survive the payment of all other Obligations.

                                   ARTICLE IV

                              CONDITIONS PRECEDENT

      4.1   Conditions of Initial Loans. The obligation of each Bank to make the
initial drawdown hereunder is subject to the condition that the Agent shall have

<PAGE>

            (b)   Continuation of Representations and Warranties. The

provision herein (other than (a) any obligation of the Borrower to pay facility
fees pursuant to Section 2.9(b) prior to such date of termination and (b)

                                   ARTICLE V

                          REPRESENTATIONS AND WARRANTIES

      The Borrower represents and warrants to the Agent and each Bank that:

      5.1   Corporate Existence; Conduct of Business. Each of the Borrower and
each Subsidiary (a) is duly formed, validly existing and in good standing under
the laws of its jurisdiction of formation, (b) is duly qualified and in good
standing in each jurisdiction in which its ownership or lease of property or the
conduct of its business requires such qualification, except where failure to be
so qualified will not have a Material Adverse Effect, and (c) possesses all
licenses, registrations and authorizations from and with any Governmental
Authority, self-regulatory organization or securities exchange necessary or
material to the conduct of its business as presently conducted. Nuveen
Investments is (a) a broker-dealer duly registered under the Exchange Act, (b) a
member in good standing of the NASD, (c) not in arrears in regard to any
assessment of the SIPC and (c) has received no notice from the SEC, MSRB, NASD
or any other Governmental Authority, self-regulatory organization or securities
exchange of any alleged rule violation or other circumstance which could
reasonably be expected to have a Material Adverse Effect.

      5.2   Authorization and Validity. The Borrower has all requisite power and
authority (corporate and otherwise) to execute and deliver each of the Loan
Documents to which it is a party and to perform its obligations thereunder. The
execution and delivery by the Borrower of the Loan Documents to which it is a
party and the performance of its obligations thereunder have been duly
authorized by proper corporate proceedings and such Loan Documents constitute
legal, valid and binding obligations of the Borrower, enforceable against the
Borrower in accordance with their terms, except as enforceability may be limited
by bankruptcy, insolvency

                                       34
<PAGE>

or similar laws affecting the enforcement of creditors' right generally or by
general principles of equity limiting the availability of equitable remedies.

      5.3   Compliance with Laws and Contracts. The Borrower and its
Subsidiaries have complied in all material respects with all applicable domestic
and foreign laws (including environmental laws), statutes, rules, regulations,
orders and restrictions of any Governmental Authority, self-regulatory
organization or securities exchange having jurisdiction over the conduct of
their respective businesses or the ownership of their respective properties
(including the Exchange Act, the Advisers Act, the Investment Company Act and
the applicable rules and regulations of the SEC, NASD, NYSE, MSRB and CFTC),
except where the failure to so comply could not reasonably be expected to have a
Material Adverse Effect. Neither the execution and delivery by the Borrower of
the Loan Documents, the application of the proceeds of the Loans, the
consummation of any transaction contemplated by the Loan Documents, nor
compliance with the provisions of the Loan Documents will, or at the relevant
time did, (a) violate any law, rule, regulation (including Regulations T, U and
X), order, writ, judgment, injunction, decree or award binding on the Borrower
or any Subsidiary or the Borrower's or any Subsidiary's charter, articles or
certificate of incorporation or by-laws (or similar governing documents), (b)
violate the provisions of or require the approval or consent of any party to any
indenture, instrument or agreement to which the Borrower or any Subsidiary is a
party or is subject, or by which it, or its property, is bound or conflict with
or constitute a default thereunder, or result in the creation or imposition of
any Lien (other than Liens permitted by Section 6.17) in, of or on the property
of the Borrower or any Subsidiary pursuant to the terms of any such indenture,
instrument or agreement, or (c) require the consent or approval of any Person,
except for any violation of, or failure to obtain an approval or consent
required under, any such indenture, instrument or agreement that could not have
a Material Adverse Effect.

      5.4   Governmental Consents. No order, consent, approval, qualification,
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, or other action in respect of, any Governmental
Authority, self-regulatory organization or securities exchange is necessary or
required in connection with the execution, delivery, consummation performance
of, or the legality, validity, binding effect or enforceability of, any of the
Loan Documents, the application of the proceeds of the Loans, or the
consummation of any other transaction contemplated by the Loan Documents.
Neither the Borrower nor any Subsidiary is in default under or in violation of
any foreign, federal, state or local law, rule, regulation, order, writ,
judgment, injunction, decree or award binding upon or applicable to the Borrower
or such Subsidiary, in each case the consequence of which default or violation
could reasonably be expected to have a Material Adverse Effect.

      5.5   Financial Statements. The Borrower has heretofore furnished to each
of the Banks the December 31, 2004 audited consolidated financial statements for
the Borrower and its Subsidiaries (the "Financial Statements"). The Financial
Statements were prepared in accordance with GAAP and fairly present the
consolidated financial condition, results of operations, changes in
stockholders' equity and cash flows of the Borrower and its Subsidiaries at such
date and for the period then ended.

                                       35
<PAGE>

      5.6 Material Adverse Change. No material adverse change in the business,
Property, condition (financial or otherwise), performance or results of
operations of the Borrower and its Subsidiaries taken as a whole has occurred
since December 31, 2004.

      5.7 Taxes. The Borrower and its Subsidiaries have filed or caused to be
filed on a timely basis and in correct form all United States federal and
applicable state tax returns and other material tax returns which are required
to be filed and have paid all material taxes due pursuant to such returns or
pursuant to any assessment received by the Borrower or any Subsidiary, except
such taxes, if any, as are being contested in good faith and as to which
adequate reserves have been provided in accordance with GAAP. As of the date
hereof, the United States income tax returns of the Borrower on a consolidated
basis have been audited by the Internal Revenue Service through its fiscal year
ending December 31, 1997 and, to the Borrower's knowledge, there are no pending
audits or investigations regarding the Borrower's or its Subsidiaries' federal,
state or local tax returns which could reasonably be expected to have a Material
Adverse Effect. No tax liens have been filed and no claims are being asserted
with respect to any such taxes which could reasonably be expected to have a
Material Adverse Effect. The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries in respect of any taxes or other governmental
charges are in accordance with GAAP.

      5.8 Litigation and Contingent Obligations. There is no litigation,
arbitration, proceeding, inquiry or investigation by any Governmental Authority,
self-regulatory organization or securities exchange pending or, to the knowledge
of any of the Borrower's officers, threatened against or affecting the Borrower
or any Subsidiary or any of their respective Properties which could reasonably
be expected to have a Material Adverse Effect or to prevent, enjoin or unduly
delay the making of the Loans or the consummation of the transactions
contemplated by this Agreement. Neither the Borrower nor any Subsidiary has any
material contingent obligations not provided for or disclosed in the Financial
Statements.

      5.9 Subsidiaries. Schedule 5.9 contains an accurate list of all
Subsidiaries as of the date of this Agreement, setting forth their respective
jurisdictions of formation and the percentage of their capital stock or other
equity interests owned by the Borrower or other Subsidiaries. Except as set
forth on Schedule 5.9 and except for Seed Money, as of the date hereof, the
Borrower does not own or hold, directly or indirectly, any capital stock or
equity security of, or any equity partnership interest in, any Person other than
such Subsidiaries.

      5.10 ERISA. Except as disclosed on Schedule 5.10, neither the Borrower nor
any other member of the Controlled Group maintains any Single Employer Plan, and
no Single Employer Plan has any Unfunded Liability. Neither the Borrower nor any
other member of the Controlled Group maintains, or is obligated to contribute
to, any Multiemployer Plan or has incurred, or is reasonably expected to incur,
any withdrawal liability to any Multiemployer Plan. Each Plan complies in all
material respects with all applicable requirements of law and regulations.
Neither the Borrower nor any other member of the Controlled Group has, with
respect to any Plan, failed to make any contribution or pay any amount required
under Section 412 of the Code or Section 302 of ERISA or the terms of such Plan
which could reasonably be expected to be in excess of $5,000,000. There are no
pending or, to the knowledge of the Borrower, threatened claims, actions,
investigations or lawsuits against any Plan, any fiduciary thereof, or the
Borrower or any other member of the Controlled Group with respect to a Plan

                                       36
<PAGE>

which could reasonably be expected to have a Material Adverse Effect. Neither
the Borrower nor any other member of the Controlled Group has engaged in any
prohibited transaction (as defined in Section 4975 of the Code or Section 406 of
ERISA) in connection with any Plan which would subject such Person to any
material liability. Within the last five years neither the Borrower nor any
other member of the Controlled Group has engaged in a transaction which resulted
in a Single Employer Plan with an Unfunded Liability being transferred out of
the Controlled Group. No Termination Event has occurred or is reasonably
expected to occur with respect to any Plan which is subject to Title IV of
ERISA.

      5.11 Defaults. No Event of Default or Default has occurred and is
continuing.

      5.12 Federal Reserve Regulations. Neither the Borrower nor any Subsidiary
is engaged, directly or indirectly, principally, or as one of its important
activities, in the business of extending or arranging for the extension of,
credit for the purpose of purchasing or carrying Margin Stock (other than in
connection with the Stock Repurchase). No part of the proceeds of any Loan will
be used in a manner which would violate, or result in any violation of,
Regulation T, Regulation U or Regulation X. Neither the making of a Loan
hereunder or the use of the proceeds thereof will violate or be inconsistent
with the provisions of, Regulation T, Regulation U or Regulation X. Following
the application of the proceeds of the Loans, less than 25% of the value (as
determined by any reasonable method) of the assets of the Borrower and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder taken as a whole have been, and will continue to be,
represented by Margin Stock.

      5.13 Investment Company; Public Utility Holding Company. The Borrower is
not an "investment company" or a company "controlled" by an "investment company"
within the meaning of the Investment Company Act of 1940, as amended. Neither
the Borrower nor any Subsidiary is subject to regulation under the Public
Utility Holding Company Act of 1935, as amended.

      5.14 Certain Fees. No broker's or finder's fee or commission was, is or
will be payable by the Borrower or any Subsidiary with respect to any of the
transactions contemplated by this Agreement. The Borrower agrees to indemnify
the Agent and the Banks against, and agrees that it will hold each of them
harmless from, any claim, demand or liability for any broker's fees, finder's
fees or commissions alleged to have been incurred by the Borrower in connection
with any of the transactions contemplated by this Agreement and any expenses
(including Attorney Costs for the Agent or any Bank) arising in connection with
any such claim, demand or liability. No other similar fee or commissions will be
payable by the Borrower or any Subsidiary for any other services rendered to the
Borrower or such Subsidiary ancillary to any of the transactions contemplated by
this Agreement.

      5.15 Ownership of Properties. The Borrower and its Subsidiaries have a
subsisting leasehold interest in, or good and marketable title, free of all
Liens, other than those permitted by Section 6.17, to all of the properties and
assets reflected in the Financial Statements as being owned by it, except for
assets sold, transferred or otherwise disposed of in the ordinary course of
business since the date thereof and such defects of title and Liens as could
not, individually or in the aggregate, have a Material Adverse Effect. To the
knowledge of the Borrower, there are no actual, threatened or alleged defaults
with respect to any lease of real property under which

                                       37
<PAGE>

the Borrower or any Subsidiary is lessee or lessor which, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

      5.16 Material Agreements. Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any charter or other company
restriction which could reasonably be expected to have a Material Adverse
Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfilment of any of the obligations, covenants or
conditions contained in any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect.

      5.17 Insurance. The Borrower and its Subsidiaries maintain with
financially sound and reputable insurance companies insurance on their Property
in such amounts and covering such risk as is consistent with sound business
practice.

      5.18 Disclosure. None of the (a) information, exhibits or reports
furnished or to be furnished by the Borrower or any Subsidiary to the Agent or
to any Bank in connection with the negotiation of the Loan Documents, taken as a
whole, or (b) representations or warranties of the Borrower or any Subsidiary
contained in this Agreement, the other Loan Documents or any other document,
certificate or written statement furnished to the Agent or the Banks by or on
behalf the Borrower or any Subsidiary pursuant to this Agreement contained,
contains or will contain any untrue statement of a material fact or omitted,
omits or will omit to state a material fact necessary in order to make the
statements contained herein or therein not misleading in light of the
circumstances in which they were made. There is no fact known to the Borrower
(other than matters of a general economic nature) that has had or could
reasonably be expected to have a Material Adverse Effect and that has not been
disclosed herein or in such other documents, certificates and statements
furnished to the Banks for use in connection with the transactions contemplated
by this Agreement.

      5.19 Solvency. The Borrower is, and after giving effect to the incurrence
of the Obligations will be, Solvent.

      5.20 Senior Debt. The Obligations shall be at least pari passu with all
other senior unsecured debt of the Borrower.

                                   ARTICLE VI

                                    COVENANTS

Subsidiary, a system of accounting established and administered in accordance
with GAAP, consistently applied, and will furnish to the Agent, with sufficient

                                       38
<PAGE>

      with GAAP on a consolidated and consolidating basis (consolidating
      statements need not be certified by such accountants) for itself and its
      Subsidiaries, including balance sheets as of the end of such period and
      related statements of income, and changes in stockholders' equity and cash
      flows (provided that so long as the common stock of the Borrower is listed
      for trading on the NYSE, the foregoing requirement as to the Borrower's
      consolidated financial statements may be satisfied by the delivery of the
      Borrower's Annual Report to Stockholders and its Annual Report on Form
      10-K filed with the SEC containing such information) and accompanied by
      (i) any management letter prepared by such accountants and (ii) a
      certificate of such accountants that, in the course of the examination
      necessary for their certification of the foregoing, they have obtained no
      knowledge of any Event of Default or Default, or if, in the opinion of
      such accountants, any Event of Default or Default shall exist, stating the
      nature and status thereof.

            (b) As soon as practicable and in any event within 45 days after the
      close of the first three fiscal quarters of each of its fiscal years, for
      itself and its Subsidiaries, consolidated unaudited balance sheets as at
      the close of each such period and consolidated statements of income,
      changes in stockholders' equity and cash flows for the period from the
      beginning of such fiscal year to the end of such fiscal quarter, all
      certified by its chief financial officer (provided that so long as the
      common stock of the Borrower is listed for trading on the NYSE, the
      foregoing requirement as to the Borrower's consolidated financial
      statements may be satisfied by the delivery of the Borrower's Quarterly
      Report on Form 10-Q as filed with the SEC containing such information.

            (c) Together with the financial statements required by clauses (a)
      and (b) above and additionally for purposes of determining the Applicable
      Margin within 45 days after the close of the fourth fiscal quarter of each
      fiscal year (which preliminary determination shall be subject to
      adjustment upon receipt of audited annual financial statements (or Form
      10-K) and shall not be deemed to constitute a misrepresentation or breach
      if prepared in good faith and the audited numbers differ from the
      unaudited fourth quarter results), a compliance certificate in
      substantially the form of Exhibit C signed by its chief financial officer
      showing the calculations necessary to determine compliance with this
      Agreement and stating that no Event of Default or Default exists, or if

      officer of the Borrower knows that any Termination Event has occurred with
      respect to any Plan, a statement, signed by the chief financial officer of
      the Borrower, describing such Termination Event and the action which the
      Borrower proposes to take with respect thereto.

            (e) As soon as possible and in any event within 10 days after any
      officer of the Borrower learns thereof, notice of the assertion or
      commencement of any claim, action, litigation, suit or proceeding against
      or affecting the Borrower or any Subsidiary, including any investigation
      or proceeding commenced by the SEC, NASD, MSRB,

                                       39
<PAGE>

      NYSE or any other Governmental Authority, self-regulatory organization or
      securities exchange, which could have a Material Adverse Effect.

            (f) Promptly upon the furnishing thereof to the shareholders of the
      Borrower copies of all financial statements, reports and proxy statements
      so furnished.

            (g) Within 15 days after the filing thereof, copies of all
      registration statements and annual, quarterly, monthly or other regular
      reports which the Borrower or any Subsidiary files with the SEC.

            (h) Such other information (including non-financial information) as
      the Agent or any Bank may from time to time reasonably request.

      Documents required to be delivered pursuant to Section 6.1 (to the extent
any such documents are included in materials otherwise filed with the SEC) may
be delivered electronically and if so delivered, shall be deemed to have been
delivered on the date (i) on which the Borrower posts such documents, or
provides a link thereto on the Borrower's website on the Internet at the website
address listed on Schedule 9.2; or (ii) on which such documents are posted on
the Borrower's behalf on IntraLinks/IntraAgency or another relevant website, if
any, to which each Bank and the Agent have access (whether a commercial,
third-party website or whether sponsored by the Agent); provided that: (i) the
Borrower shall deliver paper copies of such documents to the Agent or any Bank
that requests the Borrower to deliver such paper copies until a written request
to cease delivering paper copies is given by the Agent or such Bank and (ii) the
Borrower shall notify (which may be by facsimile or electronic mail) the Agent
and each Bank of the posting of any such documents and provide to the Agent by
electronic mail electronic versions (i.e., soft copies) of such documents.
Notwithstanding anything contained herein, in every instance the Borrower shall
be required to provide paper copies of the Compliance Certificates required by
Section 6.1(c) to the Agent and each of the Banks. Except for such Compliance
Certificates, the Agent shall have no obligation to request the delivery or to
maintain copies of the documents referred to above, and in any event shall have
no responsibility to monitor compliance by the Borrower with any such request
for delivery, and each Bank shall be solely responsible for requesting delivery
to it or maintaining its copies of such documents.

      6.2 Use of Proceeds. The Borrower will use the proceeds of the Loans
solely to (a) consummate the Stock Repurchase and/or (b) to repay and retire all
or a portion of the Senior Notes, and in each case to pay related transaction
fees and expenses. The Borrower will not, and will not permit any Subsidiary to,
use any of the proceeds of the Loans to purchase or carry any Margin Stock in
violation of Regulation T, Regulation U or Regulation X.

      6.3 Notice of Default. Within five days after any officer of the Borrower
has knowledge thereof, the Borrower will give notice in writing to the Banks of
the occurrence of (a) any Event of Default or Default and (b) any other event or
development, financial or other, relating specifically to the Borrower or any
Subsidiary (and not of a general economic or political nature) which could
reasonably be expected to have a Material Adverse Effect.

      6.4 Conduct of Business. The Borrower will, and will cause each Subsidiary
to, (a) subject to Section 6.12(c), preserve and maintain its corporate
existence, rights, franchises and

                                       40
<PAGE>

privileges in the jurisdiction of its formation, (b) maintain all registrations,
licenses, consents, approvals and authorizations from and with any Governmental
Authority, self-regulatory organization or securities exchange necessary or
material to the conduct of its business and (c) qualify and remain qualified in
each other jurisdiction in which its ownership or lease of property or the
conduct of its business requires such qualification, except where failure to
qualify could not have a Material Adverse Effect. The Borrower will not, and
will not permit any Subsidiary to, engage in any material line of business
substantially different from those lines of business carried on by them on the
date hereof (provided that further entry into the financial services business,
as well as service businesses related thereto, will not be prohibited by this
Section 6.4).

      6.5 Taxes. The Borrower will, and will cause each Subsidiary to, timely

                                    THE AGENT

      8.1 Appointment and Authorization of Agent. Each Bank hereby irrevocably
(subject to Section 8.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement

                                       48

or any other Loan Document, together with such powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary contained
elsewhere in this Agreement or in any other Loan Document, the Agent shall not
have any duties or responsibilities, except those expressly set forth herein,
nor shall the Agent have or be deemed to have any fiduciary relationship with
any Bank, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the Agent. Without limiting the generality
of the foregoing sentence, the use of the term "agent" herein and in the other
Loan Documents with reference to the Agent is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties.

      8.2 Delegation of Duties. The Agent may execute any of its duties under
this Agreement or any other Loan 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
Agent shall not be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful
misconduct.

      8.3 Liability of Agent. 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 Agreement or any other Loan 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 Bank for any recital, statement, representation or warranty made by the
Borrower or any officer thereof, contained herein or in any other Loan Document,
or in any certificate, report, statement or other document referred to or
provided for in, or received by the Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of the Borrower or any other party to any Loan
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Bank to ascertain or to inquire as
to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of the Borrower or any Affiliate thereof.

      8.4 Reliance by Agent. The 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,
facsimile, electronic communication 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 the Borrower), independent
accountants and other experts selected by the Agent. The Agent shall be fully
justified in failing or refusing to take any action under this Agreement or any
other Loan Document unless it shall first receive such advice or concurrence of
the Majority Banks as it deems appropriate and, if it so requests, it shall
first be indemnified to its satisfaction by the Banks against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this

                                       49
<PAGE>

Agreement or any other Loan Document in accordance with a request or consent of
the Majority Banks or all Banks, if required hereunder, and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Banks. Where this Agreement expressly permits or prohibits an action unless the
Majority Banks or all Banks otherwise determine, the Agent shall, and in all
other instances, the Agent may, but shall not be required to, initiate any
solicitation for the consent or a vote of the Banks. For purposes of determining
compliance with the conditions specified in Section 4.1, each Bank that has
signed this 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 Agent
to such Bank for consent, approval, acceptance or satisfaction, or required
thereunder to be consented to or approved by or acceptable or satisfactory to a
Bank.

      8.5 Notice of Default. The 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 Agent for the account of the Banks, unless the Agent shall have received
written notice from a Bank or the Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default". The Agent will notify the Banks of its receipt of any such
notice. The Agent shall take such action with respect to such Default or Event
of Default as may be requested by the Majority Banks in accordance with Article
VII; provided that unless and until the Agent has received any such request, the
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 Banks.

      8.6 Credit Decision; Disclosure of Information by Agent. Each Bank
acknowledges that no Agent-Related Person has made any representation or
warranty to it, and that no act by the Agent hereafter taken, including any
consent to and acceptance of any assignment or review of the affairs of the
Borrower or any Affiliate thereof, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Bank as to any
matter, including whether Agent-Related Persons have disclosed material
information in their possession. Each Bank represents to the Agent that it has,
independently and without reliance upon any Agent-Related Person 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 Borrower and
its Subsidiaries, and all applicable bank or other regulatory laws relating to
the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to the Borrower hereunder. Each Bank also
represents that it will, independently and without reliance upon any
Agent-Related Person 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 Agreement and
the other Loan 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 Banks by
the Agent herein, the Agent shall not have any duty or responsibility to provide
any Bank with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of the Borrower or any of its Affiliates which may come into
the possession of any Agent-Related Person.

                                       50

      8.7 Indemnification of Agent. Whether or not the transactions contemplated
hereby are consummated, the Banks shall indemnify upon demand each Agent-Related
Person (to the extent not reimbursed by or on behalf of the Borrower and without
limiting the obligation of the Borrower to do so), pro rata, and hold harmless
each Agent-Related Person from and against any and all liabilities indemnified
by the Borrower pursuant to Section 9.5; provided that no Bank shall be liable
for the payment to any Agent-Related Person of any portion of such indemnified
liabilities to the extent determined in a final, non-appealable judgment by a
court of competent jurisdiction to have resulted from such Person's own gross
negligence or willful misconduct; provided that no action taken in accordance
with the directions of the Majority Banks shall be deemed to constitute gross
negligence or willful misconduct for purposes of this Section. Without
limitation of the foregoing, each Bank shall reimburse the Agent upon demand for
its ratable share of any costs or out-of-pocket expenses (including Attorney
Costs and the costs and expenses incurred in connection with the use of
Intralinks, Inc. or other comparable information transmission systems in
connection with this Agreement) incurred by the 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 Agreement,
any other Loan Document, or any document contemplated by or referred to herein,
to the extent that the Agent is not reimbursed for such expenses by or on behalf
of the Borrower. The undertaking in this Section shall survive termination of
the Commitments, the payment of all Obligations and the resignation of the
Agent.

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

      8.9 Successor Agent. The Agent may, and at the request of the Majority
Banks shall, resign as Agent upon 30 days' notice to the Banks. If the Agent
resigns under this Agreement, the Majority Banks shall appoint from among the
Banks a successor administrative agent for the Banks which successor
administrative agent shall be consented to by the Borrower at all times other
than during the existence of an Event of Default (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 Agent,
the Agent may appoint, after consulting with the Banks and the Borrower, a
successor administrative agent from among the Banks. Upon the acceptance of its
appointment as successor administrative agent hereunder, the Person acting as
such successor administrative agent shall succeed to all the rights, powers and
duties of the retiring Agent, and the term "Agent" shall mean such successor
administrative agent, and the retiring Agent's appointment, powers and duties as
Agent shall be terminated without any other or further act or deed on the part
of any other Bank. After any retiring Agent's resignation

                                       51
<PAGE>

hereunder as Agent, the provisions of this Article VIII and Sections 9.4 and 9.5
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent under this Agreement. If no successor administrative agent
has accepted appointment as Agent by the date which is 30 days following a
retiring Agent's notice of resignation, the retiring Agent's resignation shall
nevertheless thereupon become effective and the Banks shall perform all of the
duties of the Agent hereunder until such time, if any, as the Majority Banks
appoint a successor agent as provided for above.

      8.10 Other Agents. None of the Banks identified on the facing page or
signature pages of this agreement as a "Syndication Agent" or a "Documentation
Agent" (or a similar title other than "Administrative Agent") or as the
"Arranger" shall have any right, power, obligation, liability, responsibility or
duty under this Agreement other than those applicable to all Banks as such.
Without limiting the foregoing, none of the Banks so identified shall have or be
deemed to have any fiduciary relationship with any Bank. Each Bank acknowledges
that it has not relied, and will not rely, on any of the Banks so identified in
deciding to enter into this Agreement or in taking or not taking action
hereunder.

      8.11 Withholding Tax. (a) (i) Each Bank that is not a "United States
person" within the meaning of Section 7701(a)(30) of the Code (a "Foreign Bank")
shall deliver to the Agent, prior to receipt of any payment subject to
withholding under the Code (or upon accepting an assignment of an interest
herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Foreign Bank and entitling it to an
exemption from, or reduction of, withholding tax on all payments to be made to
such Foreign Bank by the Borrower pursuant to this Agreement) or IRS Form W-8ECI
or any successor thereto (relating to all payments to be made to such Foreign
Bank by the Borrower pursuant to this Agreement) or such other evidence
satisfactory to the Borrower and the Agent that such Foreign Bank is entitled to
an exemption from, or reduction of, U.S. withholding tax, including any
exemption pursuant to Section 881(c) of the Code. Thereafter and from time to
time, each such Foreign Bank shall (A) promptly submit to the 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 United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Borrower and the Agent of any available exemption from or reduction of, United
States withholding taxes in respect of all payments to be made to such Foreign
Bank by the Borrower pursuant to this Agreement, (B) promptly notify the Agent
of any change in circumstances which would modify or render invalid any claimed
exemption or reduction and (C) take such steps as shall not be materially
disadvantageous to it, in the reasonable judgment of such Bank, and as may be
reasonably necessary (including the re-designation of its Lending Office) to
avoid any Requirement of Law that the Borrower make any deduction or withholding
for taxes from amounts payable to such Foreign Bank.

            (ii) Each Foreign Bank, to the extent it does not act or ceases to
      act for its own account with respect to any portion of any sums paid or
      payable to such Bank under any of the Loan Documents (for example, in the
      case of a typical participation by such Bank), shall deliver to the Agent
      on the date when such Foreign Bank ceases to act for its own account with
      respect to any portion of any such sums paid or payable, and at such other
      times as may be necessary in the determination of the Agent (in the
      reasonable exercise

                                       52
<PAGE>

      of its discretion), (A) two duly signed completed copies of the forms or
      statements required to be provided by such Bank as set forth above, to
      establish the portion of any such sums paid or payable with respect to
      which such Bank acts for its own account that is not subject to U.S.
      withholding tax, and (B) two duly signed completed copies of IRS Form
      W-8IMY (or any successor thereto), together with any information such Bank
      chooses to transmit with such form, and any other certificate or statement
      of exemption required under the Code, to establish that such Bank is not
      acting for its own account with respect to a portion of any such sums
      payable to such Bank.

            (iii) The Borrower shall not be required to pay any additional
      amount to any Foreign Bank under Section 3.1 (A) with respect to any Taxes
      required to be deducted or withheld on the basis of the information,
      certificates or statements of exemption such Bank transmits with an IRS
      Form W-8IMY pursuant to this Section 8.11(a) or (B) if such Bank shall
      have failed to satisfy the foregoing provisions of this Section 8.11(a);
      provided that if such Bank shall have satisfied the requirement of this
      Section 8.11(a) on the date such Bank became a Bank or ceased to act for
      its own account with respect to any payment under any of the Loan
      Documents, nothing in this Section 8.11(a) shall relieve the Borrower of
      its obligation to pay any amounts pursuant to Section 3.1 in the event
      that, as a result of any change in any applicable law, treaty or
      governmental rule, regulation or order, or any change in the
      interpretation, administration or application thereof, such Bank is no
      longer properly entitled to deliver forms, certificates or other evidence
      at a subsequent date establishing the fact that such Bank or other Person
      for the account of which such Bank receives any sums payable under any of
      the Loan Documents is not subject to withholding or is subject to
      withholding at a reduced rate.

            (iv) The Agent may, without reduction, withhold any Taxes required
      to be deducted and withheld from any payment under any of the Loan
      Documents with respect to which the Borrower is not required to pay
      additional amounts under this Section 8.11(a).

      (b) Upon the request of the Agent, each Bank that is a "United States
person" within the meaning of Section 7701(a)(30) of the Code shall deliver to
the Agent two duly signed completed copies of IRS Form W-9. If such Bank fails
to deliver such forms, then the Agent may withhold from any interest payment to
such Bank an amount equivalent to the applicable back-up withholding tax imposed
by the Code, without reduction.

      (c) If any Governmental Authority asserts that the Agent did not properly
withhold or backup withhold, as the case may be, any tax or other amount from
payments made to or for the account of any Bank, such Bank shall indemnify the
Agent therefor, including all penalties and interest, any taxes imposed by any
jurisdiction on the amounts payable to the Agent under this Section, and costs
and expenses (including Attorney Costs) of the Agent. The obligation of the
Banks under this Section shall survive the termination of the Commitments,
repayment of all other Obligations hereunder and the resignation of the Agent.

      8.12 Agent May File Proofs of Claim. In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceeding relative to the Borrower,
the Agent (irrespective of whether the

                                       53
<PAGE>

principal of any Loan shall then be due and payable as herein expressed or by
declaration or otherwise and irrespective of whether the Agent shall have made
any demand on the Borrower) shall be entitled and empowered, by intervention in
such proceeding or otherwise

            (a) to file and prove a claim for the whole amount of the principal
      and interest owing and unpaid in respect of the Loans and all other
      Obligations that are owing and unpaid and to file such other documents as
      may be necessary or advisable in order to have the claims of the Banks and
      the Agent (including any claim for the reasonable compensation, expenses,
      disbursements and advances of the Banks and the Agent and their respective
      agents and counsel and all other amounts due the Banks and the Agent under
      Sections 2.9, 9.4 and 9.5) allowed in such judicial proceeding; and

            (b) to collect and receive any monies or other property payable or
      deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Bank to make such payments to the Agent and, in the event that the Agent
shall consent to the making of such payments directly to the Banks, to pay to
the Agent any amount due for the reasonable compensation, expenses,
disbursements and advances of the Agent and its agents and counsel, and any
other amounts due the Agent under Sections 2.9, 9.4 and 9.5.

      Nothing contained herein shall be deemed to authorize the Agent to
authorize or consent to or accept or adopt on behalf of any Bank any plan of
reorganization, arrangement, adjustment or composition affecting the Obligations
or the rights of any Bank or to authorize the Agent to vote in respect of the
claim of any Bank in any such proceeding.

                                   ARTICLE IX

                                  MISCELLANEOUS

      9.1 Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent with respect to any
departure by the Borrower therefrom, shall be effective unless the same shall be
in writing and signed by the Majority Banks (or by the Agent at the written
request of the Majority Banks) and the Borrower and acknowledged by the Agent,
and then any such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided that no such
waiver, amendment, or consent shall:

            (a) increase or extend the Commitment of any Bank (or reinstate any
      Commitment terminated pursuant to Section 7.2) without the written consent
      of such Bank;

            (b) postpone or delay any date fixed by this Agreement or any other
      Loan Document for any payment of principal, interest, fees or other
      amounts due to the Banks (or any of them) hereunder or under any other
      Loan Document without the written consent of each Bank directly affected
      thereby;

                                       54
<PAGE>

            (c) reduce the principal of, or the rate of interest specified
      herein on any Loan, or (subject to clause (ii) below) any fee or other
      amount payable hereunder or under any other Loan Document without the
      written consent of each Bank directly affected thereby; provided that only
      the consent of the Majority Banks shall be necessary to amend the
      definition of Default Rate or to waive any obligation of the Borrower to
      pay interest at the Default Rate;

            (d) change the aggregate Pro Rata Shares which is required for the
      Banks or any of them to take any action hereunder without the consent of
      each Bank; or

            (e) amend this Section or Section 2.13, or any provision herein
      providing for consent or other action by all Banks without the written
      consent of each Bank;

and provided, further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Majority Banks or all the
Banks, as the case may be, affect the rights or duties of the Agent under this
Agreement or any other Loan Document, and (ii) the Fee Letter may be amended, or
rights or privileges thereunder waived, in a writing executed by the parties
thereto.

      9.2 Notices. (a) All notices, requests and other communications shall be
in writing (including, unless the context expressly otherwise provides, by
facsimile transmission, provided that any matter transmitted by facsimile (i)
shall be immediately confirmed by a telephone call to the recipient at the
number specified on Schedule 9.2, and (ii) shall be followed promptly by
delivery of a hard copy original thereof) and mailed, faxed or delivered, to the
address or facsimile number specified for notices on Schedule 9.2; or, as
directed to the Borrower or the Agent, to such other address as shall be
designated by such party in a written notice to the other parties, and as
directed to any other party, at such other address as shall be designated by
such party in a written notice to the Borrower and the Agent.

            (b) All such notices, requests and communications shall, when
      transmitted by overnight delivery, or faxed, be effective when delivered
      for overnight (next-day) delivery, or transmitted in legible form by
      facsimile machine, respectively, or if mailed, upon the third Business Day
      after the date deposited into the U.S. mail, or if delivered, upon
      delivery; except that notices pursuant to Article II or VIII shall not be
      effective until actually received by the Agent.

            (c) Any agreement of the Agent and the Banks herein to receive
      certain notices by telephone or facsimile is solely for the convenience
      and at the request of the Borrower. The Agent and the Banks shall be
      entitled to rely on the authority of any Person purporting to be a Person
      authorized by the Borrower to give such notice and the Agent and the Banks
      shall not have any liability to the Borrower or other Person on account of
      any action taken or not taken in good faith by the Agent or the Banks in
      reliance upon such telephonic or facsimile notice. The obligation of the
      Borrower to repay the Loans shall not be affected in any way or to any
      extent by any failure by the Agent and the Banks to receive written
      confirmation of any telephonic or facsimile notice or the receipt by the
      Agent and the Banks of a confirmation which is at variance with the

                                       55
<PAGE>

      terms understood  by  the  Agent  and  the  Banks  to be  contained  in
      the telephonic or facsimile notice.

      9.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising,  on the part of the Agent or any Bank, any right,  remedy,  power or
privilege hereunder,  shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further  exercise  thereof or the exercise of any other right,  remedy,
power or privilege.

      9.4 Costs and Expenses. The Borrower shall:

            (a)  whether  or  not  the  transactions   contemplated  hereby  are
      consummated,  pay or reimburse  CNAI  (including in its capacity as Agent)
      within five Business Days after demand for all costs and expenses incurred
      by CNAI  (including  in its  capacity  as  Agent) in  connection  with the
      development,  preparation,  delivery, administration and execution of, and
      any  amendment,  supplement,  waiver  or  modification  to (in each  case,
      whether or not  consummated),  this  Agreement,  any Loan Document and any
      other  document  prepared in  connection  herewith or  therewith,  and the
      consummation  of  the  transactions   contemplated   hereby  and  thereby,
      including  Attorney Costs  incurred by CNAI  (including in its capacity as
      Agent) with respect thereto; and

            (b) pay or  reimburse  the Agent,  the Arranger and each Bank within
      five  Business  Days after  demand for all costs and  expenses  (including
      Attorney  Costs)  incurred  by them in  connection  with the  enforcement,
      attempted  enforcement,  or  preservation  of any rights or remedies under
      this Agreement or any other Loan Document during the existence of an Event
      of Default or after  acceleration  of the Loans  (including  in connection
      with any "workout" or restructuring  regarding the Loans, and including in
      any Insolvency Proceeding or appellate proceeding).

      9.5 Indemnity.  Whether or not the  transactions  contemplated  hereby are
consummated,  the Borrower  shall  indemnify  and hold  harmless the Agent,  the
Arranger, each Bank and each of their Affiliates and their respective directors,
officers, employees, advisors and agents (each, an "Indemnified Party") from and
against (and will reimburse each Indemnified Party as the same are incurred) any
and all losses, claims, damages,  liabilities,  and expenses (including Attorney
Costs) that may be incurred  by or asserted or awarded  against any  Indemnified
Party,  in each  case  arising  out of or in  connection  with or by  reason  of
(including in  connection  with any  investigation,  litigation or proceeding or
preparation of a defense in connection  therewith) any matters  contemplated  by
this Agreement,  any related  transaction or any use made or proposed to be made
with  the  proceeds  thereof  unless  and  only to the  extent  that,  as to any
Indemnified Party, it shall be determined in a final nonappealable judgment by a
court of competent jurisdiction that such losses, claims,  damages,  liabilities
or expenses resulted  primarily from the gross negligence or willful  misconduct
of such Indemnified  Party.  Notwithstanding  the foregoing,  the Borrower shall
have no  obligation  to any  Indemnified  Party in respect  of  losses,  claims,
damages,  liabilities or expenses  arising from (a) disputes  between Banks, the
Agent  and/or  the  Arranger  or  (b)  disputes  between  the  Borrower  and  an
Indemnified  Party,  with respect to which the Borrower is the prevailing  party
unless such losses, claims,  damages,  liabilities or expenses under this clause
(b) arise from the negligence (but not gross

                                       56
<PAGE>

negligence or willful  misconduct) of such Indemnified  Party. In no event shall
any Indemnified Party be liable for special, consequential, punitive or indirect
damages.

      9.6 [RESERVED.]

      9.7 Payments Set Aside. To the extent that the Borrower makes a payment to
the Agent or the Banks, or the Agent or any Bank exercises its right of set-off,
and such  payment  or the  proceeds  of such  set-off  or any part  thereof  are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
or required  (including  pursuant to any settlement entered into by the Agent or
such Bank in its  discretion)  to be repaid to a trustee,  receiver or any other
party,  in connection with any Insolvency  Proceeding or otherwise,  then (a) to
the extent of such recovery the obligation or part thereof  originally  intended
to be  satisfied  shall be revived and  continued in full force and effect as if
such  payment had not been made or such set-off had not  occurred,  and (b) each
Bank severally  agrees to pay to the Agent upon demand its pro rata share of any
amount so recovered from or repaid by the Agent,  plus interest thereon from the
date of such  demand to the date such  payment is made at a rate per annum equal
to the Federal Funds Rate from time to time in effect.

      9.8  Successors and Assigns.  The  provisions of this  Agreement  shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns,  except that the Borrower may not assign or transfer any
of its rights or  obligations  under this  Agreement  without the prior  written
consent of the Agent and each Bank.

      9.9 Assignments,  Participations,  etc. (a) Any Bank may, with the written
consent of the Borrower at all times other than during the existence of an Event
of  Default  and  the  Agent,  which  consent  of  the  Borrower  shall  not  be
unreasonably  withheld,  at any time assign and delegate to one or more Eligible
Assignees  (provided that no written  consent of the Borrower or the Agent shall
be required in connection  with any  assignment  and  delegation by a Bank to an
Approved Fund or to another Eligible Assignee that is an Affiliate of such Bank)
(each  an  "Assignee")  all,  or any  ratable  part of  all,  of the  Loan,  the
Commitments and the other rights and  obligations of such Bank  hereunder,  in a
minimum  amount (which minimum amount shall not apply during the existence of an
Event of Default) of  $5,000,000;  provided  that the Borrower and the Agent may
continue  to deal  solely and  directly  with such Bank in  connection  with the
interest so assigned to an Assignee until (i) written notice of such assignment,
together  with payment  instructions,  addresses  and related  information  with
respect to the Assignee,  shall have been given to the Borrower and the Agent by
such Bank and the Assignee; (ii) such Bank and its Assignee shall have delivered
to the  Borrower  and the  Agent an  Assignment  and  Acceptance  in the form of
Exhibit E  ("Assignment  and  Acceptance")  and (iii) the  assignor  Bank or the
Assignee has paid to the Agent a processing fee in the amount of $3,500.

            (b) From and after the date that the  Agent  notifies  the  assignor
      Bank that it has received (and provided its and the Borrower's consent, if
      applicable,  with respect to) an executed  Assignment  and  Acceptance and
      payment  of  the   above-referenced   processing  fee,  (i)  the  Assignee
      thereunder  shall be a party  hereto  and,  to the extent  that rights and
      obligations hereunder have been assigned to it pursuant to such Assignment
      and Acceptance,  shall have the rights and obligations of a Bank under the
      Loan  Documents,  and (ii) the  assignor  Bank  shall,  to the extent that
      rights and  obligations

                                       57
<PAGE>

      hereunder  and under the other Loan  Documents  have been  assigned  by it
      pursuant to such Assignment and  Acceptance,  relinquish its rights and be
      released from its obligations under the Loan Documents.

            (c) Within  five  Business  Days after its  receipt of notice by the
      Agent that it has  received  an executed  Assignment  and  Acceptance  and
      payment of the processing fee, (and provided that it and the Borrower,  if
      applicable, consent to such assignment in accordance with Section 9.9(a)),
      the Borrower shall, at the request of the applicable new Assignee, execute
      and deliver to the Agent, a Note evidencing a new Assignee's assigned Loan
      and Commitment. Immediately upon each Assignee's making its processing fee
      payment under the  Assignment  and  Acceptance,  this  Agreement  shall be
      deemed to be amended to the extent,  but only to the extent,  necessary to
      reflect the addition of the Assignee and the  resulting  adjustment of the
      Commitment  arising therefrom.  The Commitment  allocated to each Assignee
      shall reduce the Commitment of the assigning Bank pro tanto.

            (d) The Agent,  acting  solely  for this  purpose as an agent of the
      Borrower,  shall  maintain  at the Agent's  Payment  Office (or such other
      office  determined  by the  Agent)  a copy  of each  assignment  agreement
      delivered  to it and a  register  for the  recordation  of the  names  and
      addresses of the Banks,  and the Commitment  of, and principal  amounts of
      the Loan owing to,  each Bank  pursuant  to the terms  hereof from time to
      time (the  "Register").  The entries in the Register  shall be conclusive,
      and the Borrower, the Agent and the Banks may treat each Person whose name
      is  recorded  in the  Register  pursuant  to the  terms  hereof  as a Bank
      hereunder for all purposes of this  Agreement,  notwithstanding  notice to
      the  contrary.  The Register  shall be  available  for  inspection  by the
      Borrower and any Bank, at any  reasonable  time and from time to time upon
      reasonable prior notice.

            (e) Any Bank,  with notice to the Borrower,  may at any time sell to
      one or more  commercial  banks  or other  Persons  not  Affiliates  of the
      Borrower  (a  "Participant")  participating  interests  in the  Loan,  the
      Commitment and the other interests of such Bank (the  "originating  Bank")
      hereunder  and under  the  other  Loan  Documents;  provided  that (i) the
      originating   Bank's   obligations   under  this  Agreement  shall  remain
      unchanged,  (ii) the originating Bank shall remain solely  responsible for
      the  performance  of such  obligations,  (iii) the  Borrower and the Agent
      shall  continue to deal solely and directly with the  originating  Bank in
      connection with the originating  Bank's rights and obligations  under this
      Agreement and the other Loan  Documents and (iv) no Bank shall transfer or
      grant any participating interest under which the Participant has rights to
      approve any  amendment  to, or any consent or waiver with respect to, this
      Agreement or any other Loan Document, except to the extent such amendment,
      consent  or  waiver  would  require  unanimous  consent  of the  Banks  as
      described  in the first  proviso to Section  9.1.  In the case of any such
      participation,  the  Participant  shall  be  entitled  to the  benefit  of
      Sections  3.1,  3.3 and 9.5 as though it were also a Bank  hereunder,  and
      shall not have any rights under this  Agreement,  or any of the other Loan
      Documents,  and all amounts  payable by the  Borrower  hereunder  shall be
      determined as if such Bank had not sold such  participation;  except that,
      if amounts  outstanding  under this Agreement are due and unpaid, or shall
      have  been  declared  or  shall  have  become  due and  payable  upon  the

                                       58
<PAGE>

      occurrence  of an Event of Default,  each  Participant  shall be deemed to
      have the right of  set-off in respect  of its  participating  interest  in
      amounts owing under this  Agreement to the same extent as if the amount of
      its participating  interest were owing directly to it as a Bank under this
      Agreement.  A  Participant  shall not be  entitled  to receive any greater
      payment under Section 3.1 or 3.3 than the applicable  Bank would have been
      entitled  to  receive  with  respect  to the  participation  sold  to such
      Participant,  unless the sale of the  participation to such Participant is
      made with the Borrower's prior written  consent.  A Participant that would
      be a Foreign  Bank if it were a Bank shall not be entitled to the benefits
      of Section 3.1 unless the Borrower is notified of the  participation  sold
      to such  Participant and such Participant  agrees,  for the benefit of the
      Borrower, to comply with Section 8.11 as though it were a Bank.

            (f) Notwithstanding any other provision in this Agreement,  any Bank
      may at any time  create a  security  interest  in, or  pledge,  all or any
      portion of its rights  under and interest in this  Agreement  and the Note
      held  by it in  favor  of any  Federal  Reserve  Bank in  accordance  with
      Regulation A of the FRB or U.S. Treasury Regulation 31 CFR Section 203.14,
      and such Federal Reserve Bank may enforce such pledge or security interest
      in any manner permitted under applicable law.

      9.10 Confidentiality. Each Bank agrees to take and to cause its Affiliates
to take normal and reasonable  precautions and exercise due care to maintain the
confidentiality  of all information  identified as "confidential" or "secret" by
the Borrower and  provided to it by the  Borrower or any  Subsidiary,  or by the
Agent on the Borrower's or any Subsidiary's  behalf, under this Agreement or any
other Loan Document, and neither it nor any of its Affiliates shall use any such
information  other than in connection  with or in  enforcement of this Agreement
and the other  Loan  Documents  or in  connection  with  other  business  now or
hereafter  existing or contemplated with the Borrower or any Subsidiary;  except
to the extent such  information  (i) was or becomes  generally  available to the
public other than as a result of  disclosure  by the Bank or (ii) was or becomes
available on a  non-confidential  basis from a source  other than the  Borrower,
provided that such source is not bound by a  confidentiality  agreement with the
Borrower known to the Bank; provided that any Bank may disclose such information
(A) at the request or pursuant to any requirement of any Governmental  Authority
to which the Bank is subject or in connection  with an  examination of such Bank
by any such authority; (B) pursuant to subpoena or other court process; (C) when
required  to  do  so  in  accordance  with  the  provisions  of  any  applicable
Requirement of Law; (D) to the extent reasonably required in connection with any
litigation  or  proceeding  to which  the  Agent,  any Bank or their  respective
Affiliates  may be party;  (E) to the extent  reasonably  required in connection
with the exercise of any remedy hereunder or under any other Loan Document;  (F)
to such Bank's independent  auditors and other  professional  advisors (it being
understood  that such auditors and other  advisors shall be required to maintain
the confidentiality of such information to the same extent as such Bank); (G) to
any  Participant  or Assignee,  actual or  potential,  provided that such Person
agrees in  writing  to keep such  information  confidential  to the same  extent
required  of the  Banks  hereunder;  (H) as to any  Bank  or its  Affiliate,  as
expressly permitted under the terms of any other document or agreement regarding
confidentiality  to which the Borrower or any  Subsidiary  is party or is deemed
party with such Bank or such Affiliate; and (I) to its Affiliates which shall be
bound by the terms of this Section 9.10.

      9.11 Set-off. In addition to any rights and remedies of the Banks provided
by law, if an Event of Default exists or the Loans have been  accelerated,  each
Bank is  authorized  at any time and from time to time,  without prior notice to
the Borrower, any such notice being waived by the Borrower to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time  or  demand,  provisional  or  final)  at  any  time  held  by,  and  other
indebtedness at any time owing by, such Bank to or for the credit or the account
of the  Borrower  against  any and all  Obligations  owing to such Bank,  now or
hereafter existing,  irrespective of whether or not the Agent or such Bank shall
have made demand  under this  Agreement or any Loan  Document and although  such
Obligations may be contingent or unmatured.  Each Bank agrees promptly to notify
the Borrower and the Agent after any such set-off and  application  made by such
Bank;  provided  that the  failure  to give such  notice  shall not  affect  the
validity of such set-off and application.

      9.12 Automatic  Debits of Fees. With respect to any fee, or any other cost
or expense (including  Attorney Costs) due and payable to the Agent, CNAI or the
Arranger,  the Borrower irrevocably authorizes CNAI to debit any deposit account
of the Borrower  with CNAI in an amount such that the aggregate  amount  debited
from  all  such  deposit  accounts  does not  exceed  such fee or other  cost or
expense.  If there are insufficient  funds in such deposit accounts to cover the
amount  of the fee or other  cost or  expense  then  due,  such  debits  will be
reversed (in whole or in part,  in CNAI's sole  discretion)  and such amount not
debited shall be deemed to be unpaid.  No such debit under this Section shall be
deemed a set-off.

      9.13  Notification  of Addresses,  Lending  Offices,  Etc. Each Bank shall
notify the Agent in writing of any  changes in the  address to which  notices to
the Bank should be  directed,  of addresses  of any Lending  Office,  of payment
instructions  in respect of all payments to be made to it hereunder  and of such
other administrative information as the Agent shall reasonably request.

      9.14  Counterparts.  This  Agreement  may be  executed  in any  number  of
separate  counterparts,  each of  which,  when so  executed,  shall be deemed an
original,  and all of such  counterparts  taken  together  shall  be  deemed  to
constitute but one and the same instrument.  Delivery of a counterpart signature
page  hereto  by  facsimile  shall  be  effective  as  delivery  of an  original
counterpart hereof.

      9.15 Severability.  The illegality or unenforceability of any provision of
this Agreement or any instrument or agreement  required  hereunder  shall not in
any way  affect  or impair  the  legality  or  enforceability  of the  remaining
provisions of this Agreement or any instrument or agreement required hereunder.

      9.16 No Third Parties Benefitted.  This Agreement is made and entered into
for the sole protection and legal benefit of the Borrower,  the Banks, the Agent
and the Agent-Related  Persons,  and their permitted successors and assigns, and
no other Person shall be a direct or indirect legal  beneficiary of, or have any
direct or indirect cause of action or claim in connection  with,  this Agreement
or any of the other Loan Documents.

      9.17  Governing  Law and  Jurisdiction.  (a) THIS  AGREEMENT AND THE NOTES
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE  WITH, THE LAW OF

                                       60
<PAGE>

THE STATE OF NEW YORK (INCLUDING  SECTION 5-1401 OF THE GENERAL  OBLIGATIONS LAW
OF THE STATE OF NEW YORK),  WITHOUT  REGARD TO  PRINCIPLES OF CONFLICTS OF LAWS;
PROVIDED  THAT THE AGENT AND THE BANKS  SHALL  RETAIN ALL RIGHTS  ARISING  UNDER
FEDERAL LAW.

            (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
      ANY OTHER LOAN  DOCUMENT  MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW
      YORK OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF NEW YORK, AND BY
      EXECUTION AND DELIVERY OF THIS AGREEMENT,  EACH OF THE BORROWER, THE AGENT
      AND THE BANKS CONSENTS,  FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE
      NON-EXCLUSIVE  JURISDICTION  OF THOSE COURTS.  EACH OF THE  BORROWER,  THE
      AGENT  AND THE BANKS  IRREVOCABLY  WAIVES  ANY  OBJECTION,  INCLUDING  ANY
      OBJECTION  TO THE  LAYING  OF VENUE OR BASED ON THE  GROUNDS  OF FORUM NON
      CONVENIENS,  WHICH IT MAY NOW OR  HEREAFTER  HAVE TO THE  BRINGING  OF ANY
      ACTION OR PROCEEDING IN SUCH  JURISDICTION IN RESPECT OF THIS AGREEMENT OR
      ANY DOCUMENT  RELATED HERETO.  THE BORROWER,  THE AGENT AND THE BANKS EACH
      WAIVE PERSONAL SERVICE OF ANY SUMMONS,  COMPLAINT OR OTHER PROCESS,  WHICH
      MAY BE MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

      9.18  Waiver of Jury  Trial.  THE  BORROWER,  THE BANKS AND THE AGENT EACH
WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION
BASED  UPON OR  ARISING  OUT OF OR  RELATED  TO THIS  AGREEMENT,  THE OTHER LOAN
DOCUMENTS,  OR THE TRANSACTIONS  CONTEMPLATED  HEREBY OR THEREBY, IN ANY ACTION,
PROCEEDING  OR OTHER  LITIGATION  OF ANY TYPE  BROUGHT BY ANY PARTY  AGAINST ANY
OTHER PARTY OR ANY AGENT-RELATED PERSON,  PARTICIPANT OR ASSIGNEE,  WHETHER WITH
RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE.  THE BORROWER,  THE BANKS
AND THE AGENT EACH  AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION  SHALL BE TRIED
BY A COURT TRIAL WITHOUT A JURY.  WITHOUT  LIMITING THE  FOREGOING,  THE PARTIES
FURTHER  AGREE  THAT  THEIR  RESPECTIVE  RIGHT TO A TRIAL BY JURY IS  WAIVED  BY
OPERATION OF THIS  SECTION AS TO ANY ACTION,  COUNTERCLAIM  OR OTHER  PROCEEDING
WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR THE OTHER LOAN  DOCUMENTS OR ANY PROVISION  HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,  RENEWALS,  SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

      9.19  Entire  Agreement.  This  Agreement,  together  with the other  Loan
Documents,  embodies the entire agreement and understanding  among the Borrower,
the Banks and the Agent, and supersedes all prior or contemporaneous  agreements
and understandings of such Persons,  verbal or written,  relating to the subject
matter hereof and thereof.

      9.20 USA PATRIOT ACT NOTIFICATION.  The following notification is provided
to the  Borrower  pursuant to Section  326 of the USA  Patriot  Act of 2001,  31
U.S.C. Section 5318:

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

      The Borrower agrees that it will provide any such requested information to
the Agent and the Banks promptly upon request.
