forth herein.

Lender shall be determined based on the Applicable Percentage of such Lender
most recently in effect, giving effect to any subsequent assignments. The

     determined by either S&P or Moody's (collectively, the "Debt Ratings") of
     the Borrower's non-credit-enhanced, senior unsecured long-term debt;
     provided that (a) if the respective Debt Ratings issued by the foregoing
     rating agencies differ by one level, then the Pricing Level for the higher
     of such Debt Ratings shall apply (with the Debt Rating for Pricing Level 1

Thereafter, each change in the Applicable Rate resulting from a publicly
announced change in the Debt Rating shall be effective during the period
commencing on the date of the public announcement thereof and ending on the date
immediately preceding the effective date of the next such change. If the rating
system of Moody's or S&P shall change, or if either such rating agency shall
cease to be in the business of rating corporate debt obligations, the Borrower
and the Lenders shall negotiate in good faith to amend this provision to reflect

     2.01 COMMITTED LOANS. Subject to the terms and conditions set forth herein,
each Lender severally agrees to make a single loan (such loan, a "Committed
Loan") denominated in Dollars to the Borrower in one draw on any single Business
Day during the Availability Period, in an aggregate amount not to exceed at any
time outstanding the amount of such Lender's Commitment; provided, however, that
after giving effect to any Committed Borrowing, (i) the Total Outstandings shall
not exceed the Aggregate Commitments, and (ii) the aggregate Outstanding Amount
of the Committed Loans of any Lender shall not exceed such Lender's Commitment.
The Borrowing shall consist of Committed Loans made simultaneously by the
Lenders in accordance with their respective Applicable Percentage. Amounts
borrowed under this Section 2.01 and repaid or prepaid may not be reborrowed.
Committed Loans may be Base Rate Loans or Eurodollar Rate Loans, as further
provided herein. Notwithstanding the foregoing, it is acknowledged and agreed
that there shall only be a single Borrowing, Committed Borrowing and Credit
Extension made under this Agreement, and after such event the Commitments shall
be automatically terminated.

     2.02 BORROWING, CONVERSIONS AND CONTINUATIONS OF COMMITTED LOANS.

     (a) The Committed Borrowing, each conversion of Committed Loans from one
Type to the other, and each continuation of Eurodollar Rate Loans shall be made
upon the Borrower's irrevocable notice to the Administrative Agent, which may be
given by telephone. Each such notice must be received by the Administrative
Agent not later than 11:00 a.m. (i) three Business Days prior to the requested
date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans
or of any conversion of Eurodollar Rate Loans to Base Rate Loans, and (ii) on
the requested date of any Borrowing of Base Rate Loans. Each telephonic notice
by the Borrower pursuant to this Section 2.02(a) must be confirmed promptly by
delivery to the Administrative Agent of a written Committed Loan Notice,
appropriately completed and signed by a Responsible Officer of the Borrower.
Each conversion to or continuation of Eurodollar Rate Loans shall be in a
principal amount of $5,000,000 or a whole multiple of $1,000,000 in


                                       20



excess thereof. Each conversion to Base Rate Loans shall be in a principal
amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each
Committed Loan Notice (whether telephonic or written) shall specify (i) whether
the Borrower is requesting a Committed Borrowing, a conversion of Committed
Loans from one Type to the other, or a continuation of Eurodollar Rate Loans,
(ii) the requested date of the Borrowing, conversion or continuation, as the
case may be (which shall be a Business Day), (iii) the principal amount of
Committed Loans to be borrowed, converted or continued, (iv) the Type of
Committed Loans to be borrowed or to which existing Committed Loans are to be
converted, and (v) if applicable, the duration of the Interest Period with
respect thereto. If the Borrower fails to specify a Type of Committed Loan in a
Committed Loan Notice or if the Borrower fails to give a timely notice
requesting a conversion or continuation, then the applicable Committed Loans
shall be made as, or converted to, Base Rate Loans. Any such automatic
conversion to Base Rate Loans shall be effective as of the last day of the
Interest Period then in effect with respect to the applicable Eurodollar Rate
Loans. If the Borrower requests a Borrowing of, conversion to, or continuation
of Eurodollar Rate Loans in any such Committed Loan Notice, but fails to specify
an Interest Period, it will be deemed to have specified an Interest Period of
one month.

     (b) Following receipt of a Committed Loan Notice, the Administrative Agent
shall promptly notify each Lender of the amount of its Applicable Percentage of
the applicable Committed Loans, and if no timely notice of a conversion or
continuation is provided by the Borrower, the Administrative Agent shall notify
each Lender of the details of any automatic conversion to Base Rate Loans
described in the preceding subsection. In the case of a Committed Borrowing,
each Lender shall make the amount of its Committed Loan available to the
Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 1:00 p.m. on the Business Day specified in the
applicable Committed Loan Notice. Upon satisfaction of the applicable conditions
set forth in Section 4.02 (and, if such Borrowing is the Credit Extension,
Section 4.01), the Administrative Agent shall make all funds so received
available to the Borrower in like funds as received by the Administrative Agent
either by (i) crediting the account of the Borrower on the books of Merrill
Lynch Capital Corporation (or one of its Affiliates) with the amount of such
funds or (ii) wire transfer of such funds, in each case in accordance with
instructions provided to (and reasonably acceptable to) the Administrative Agent
by the Borrower.

     (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be
continued or converted only on the last day of an Interest Period for such
Eurodollar Rate Loan. During the existence of a Default, no Loans may be
requested as, converted to or continued as Eurodollar Rate Loans without the
consent of the Required Lenders.

     (d) The Administrative Agent shall promptly notify the Borrower and the
Lenders of the interest rate applicable to any Interest Period for Eurodollar
Rate Loans upon determination of such interest rate.

     (e) After giving effect to all Committed Borrowings, all conversions of
Committed Loans from one Type to the other, and all continuations of Committed
Loans as the same Type, there shall not be more than ten (10) Interest Periods
in effect with respect to Committed Loans.

Each such notice shall specify the date and amount of such prepayment and the
Type(s) of Committed Loans to be prepaid and, if Eurodollar Rate Loans are to be
prepaid, the Interest Period(s) of such Loans. The Administrative Agent will
promptly notify each Lender of its receipt of each such notice, and of the
amount of such Lender's Applicable Percentage of such prepayment. If such notice
is given by the Borrower, the Borrower shall make such prepayment and the
payment amount specified in such notice shall be due and payable on the date
specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied

Administrative Agent on or prior to the date of such Disposition), and so long
as no Default shall have occurred and be continuing, the Borrower or such
Subsidiary may reinvest all or any portion of such Net Cash Proceeds in
operating assets so long as within 180 days after the receipt of such Net Cash
Proceeds, either the purchase of such assets shall have been consummated (as
certified by the Borrower in writing to the Administrative Agent) or the
Borrower shall have entered into a definitive agreement to make such a purchase,
and such purchase shall be consummated within 30 days thereafter; and provided
further, however, that any Net Cash Proceeds not subject to such definitive
agreement or so reinvested shall be immediately applied to the prepayment of the
Loans as set forth in this Section 2.05(b)(i).

     (ii) Upon the sale or issuance by the Borrower or any of its Subsidiaries
of any of its Equity Interests (other than any sales or issuances of Equity
Interests by any Subsidiary to the Borrower or another Subsidiary or by the
Borrower to its employees or directors or by the


                                       22

interest shall be made on the basis of a 360-day year and actual days elapsed
(which results in more fees or interest, as applicable, being paid than if
computed on the basis of a 365-day year). Interest shall accrue on each Loan for
the day on which the Loan is made, and shall not accrue on a Loan, or any
portion thereof, for the day on which the Loan or such portion is paid, provided
that any Loan that is repaid on the same day on which it is made shall, subject
to Section 2.12(a), bear interest for one day. Each determination by the
Administrative Agent of an interest rate or fee hereunder shall be conclusive
and binding for all purposes, absent manifest error.

     2.11 EVIDENCE OF DEBT.

     The Committed Loans made by each Lender shall be evidenced by one or more
accounts or records maintained by such Lender and by the Administrative Agent in
the ordinary course of business. The accounts or records maintained by the
Administrative Agent and each Lender shall be conclusive absent manifest error
of the amount of the Committed Loans made by the Lenders to the Borrower and the
interest and payments thereon. Any failure to so record or any error in doing so
shall not, however, limit or otherwise affect the obligation of the Borrower
hereunder to pay any amount owing with respect to the Obligations. In the event
of any conflict between the accounts and records maintained by any Lender and
the accounts and records of the Administrative


                                       24



Agent in respect of such matters, the accounts and records of the Administrative
Agent shall control in the absence of manifest error. Upon the request of any
Lender made through the Administrative Agent, the Borrower shall execute and
deliver to such Lender (through the Administrative Agent) a Note, which shall
evidence such Lender's Loans in addition to such accounts or records. Each
Lender may attach schedules to its Note and endorse thereon the date, Type (if
applicable), amount and maturity of its Loans and payments with respect thereto.

     2.12 PAYMENTS GENERALLY; ADMINISTRATIVE AGENT'S CLAWBACK.

     (a) General. All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Borrower
hereunder shall be made to the Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Administrative Agent's
Office in Dollars and in immediately available funds not later than 2:00 p.m. on
the date specified herein. The Administrative Agent will promptly distribute to
each Lender its Applicable Percentage (or other applicable share as provided
herein) of such payment in like funds as received by wire transfer to such
Lender's Lending Office. All payments received by the Administrative Agent after
2:00 p.m. shall be deemed received on the next succeeding Business Day and any
applicable interest or fee shall continue to accrue. If any payment to be made
by the Borrower shall come due on a day other than a Business Day, payment shall
be made on the next following Business Day, and such extension of time shall be
reflected in computing interest or fees, as the case may be.

     (b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the
Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Committed Borrowing of Eurodollar Rate Loans (or, in the
case of any Committed Borrowing of Base Rate Loans, prior to 12:00 noon on the
date of such Committed Borrowing) that such Lender will not make available to
the Administrative Agent such Lender's share of such Committed Borrowing, the
Administrative Agent may assume that such Lender has made such share available
on such date in accordance with Section 2.02 (or, in the case of a Committed
Borrowing of Base Rate Loans, that such Lender has made such share available in
accordance with and at the time required by Section 2.02) and may, in reliance
upon such assumption, make available to the Borrower a corresponding amount. In
such event, if a Lender has not in fact made its share of the applicable
Committed Borrowing available to the Administrative Agent, then the applicable
Lender and the Borrower severally agree to pay to the Administrative Agent
forthwith on demand such corresponding amount in immediately available funds
with interest thereon, for each day from and including the date such amount is
made available to the Borrower to but excluding the date of payment to the
Administrative Agent, at (A) in the case of a payment to be made by such Lender,
the greater of the Federal Funds Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank
compensation, plus any administrative, processing or similar fees customarily
charged by the Administrative Agent in connection with the foregoing, and (B) in
the case of a payment to be made by the Borrower, the interest rate applicable
to Base Rate Loans. If the Borrower and such Lender shall pay such interest to
the Administrative Agent for the same or an overlapping period, the
Administrative Agent shall promptly remit to the Borrower the amount of such
interest paid by the Borrower for such period. If such Lender pays its share of
the applicable Committed Borrowing to the Administrative Agent, then the amount
so paid shall constitute such Lender's Committed Loan


                                       25



included in such Committed Borrowing. Any payment by the Borrower shall be
without prejudice to any claim the Borrower may have against a Lender that shall
have failed to make such payment to the Administrative Agent.

     (ii) Payments by Borrower; Presumptions by Administrative Agent. Unless the
Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of
the Lenders hereunder that the Borrower will not make such payment, the
Administrative Agent may assume that the Borrower has made such payment on such
date in accordance herewith and may, in reliance upon such assumption,
distribute to the Lenders the amount due. In such event, if the Borrower has not
in fact made such payment, then each of the Lenders severally agrees to repay to
the Administrative Agent forthwith on demand the amount so distributed to such
Lender in immediately available funds with interest thereon, for each day from
and including the date such amount is distributed to it to but excluding the
date of payment to the Administrative Agent, at the greater of the Federal Funds
Rate and a rate determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation.

     A notice of the Administrative Agent to any Lender or the Borrower with
respect to any amount owing under this subsection (b) shall be conclusive,
absent manifest error.

     (c) Failure to Satisfy Conditions Precedent. If any Lender makes available
to the Administrative Agent funds for any Loan to be made by such Lender as
provided in the foregoing provisions of this Article II, and such funds are not
made available to the Borrower by the Administrative Agent because the
conditions to the Credit Extension set forth in Article IV are not satisfied or
waived in accordance with the terms hereof, the Administrative Agent shall
return such funds (in like funds as received from such Lender) to such Lender,
without interest.

     (d) Obligations of Lenders Several. The obligations of the Lenders
hereunder to make Committed Loans and to make payments pursuant to Section
10.04(c) are several and not joint. The failure of any Lender to make any
Committed Loan or to make any payment under Section 10.04(c) on any date
required hereunder shall not relieve any other Lender of its corresponding
obligation to do so on such date, and no Lender shall be responsible for the
failure of any other Lender to so make its Committed Loan or to make its payment
under Section 10.04(c).

     (e) Funding Source. Nothing herein shall be deemed to obligate any Lender
to obtain the funds for any Loan in any particular place or manner or to
constitute a representation by any Lender that it has obtained or will obtain
the funds for any Loan in any particular place or manner.

     2.13 SHARING OF PAYMENTS BY LENDERS. If any Lender shall, by exercising any
right of setoff or counterclaim or otherwise, obtain payment in respect of any
principal of or interest on any of the Committed Loans made by it resulting in
such Lender's receiving payment of a proportion of the aggregate amount of such
Committed Loans or accrued interest thereon greater than its pro rata share
thereof as provided herein, then the Lender receiving such greater proportion
shall (a) notify the Administrative Agent of such fact, and (b) purchase (for
cash at face value) participations in the Committed Loans of the other Lenders,
or make such other


                                       26



adjustments as shall be equitable, so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount
of principal of and accrued interest on their respective Committed Loans and
other amounts owing them, provided that:

          (i) if any such participations are purchased and all or any portion of
     the payment giving rise thereto is recovered, such participations shall be
     rescinded and the purchase price restored to the extent of such recovery,
     without interest; and

          (ii) the provisions of this Section shall not be construed to apply to
     (x) any payment made by the Borrower pursuant to and in accordance with the
     express terms of this Agreement or (y) any payment obtained by a Lender as
     consideration for the assignment of or sale of a participation in any of
     its Committed Loans to any assignee or participant, other than to the
     Borrower or any Subsidiary thereof (as to which the provisions of this
     Section shall apply).

     The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the
Borrower rights of setoff and counterclaim with respect to such participation as
fully as if such Lender were a direct creditor of the Borrower in the amount of
such participation.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 TAXES.

     (a) Payments Free of Taxes. Any and all payments by or on account of any
obligation of the Borrower hereunder or under any other Loan Document shall be
made free and clear of and without reduction or withholding for any Indemnified
Taxes or Other Taxes, provided that if the Borrower shall be required by
applicable law to deduct any Indemnified Taxes (including any Other Taxes) from
such payments, then (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) the Administrative Agent or Lender,
as the case may be, receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions
and (iii) the Borrower shall timely pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

     (b) Payment of Other Taxes by the Borrower. Without limiting the provisions
of subsection (a) above, the Borrower shall timely pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

     (c) Indemnification by the Borrower. The Borrower shall indemnify the
Administrative Agent, each Lender, within 10 days after demand therefor, for the
full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes
or Other Taxes imposed or asserted on or attributable to amounts payable under
this Section) paid by the Administrative Agent or such Lender and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or


                                       27



legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender (with a copy to the Administrative Agent), or by the
Administrative Agent on its own behalf or on behalf of a Lender shall be
conclusive absent manifest error.

     (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority,
the Borrower shall deliver to the Administrative Agent the original or a
certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of
such payment reasonably satisfactory to the Administrative Agent.

     (e) Status of Lenders. Any Foreign Lender that is entitled to an exemption
from or reduction of withholding tax under the law of the jurisdiction in which
the Borrower is resident for tax purposes, or any treaty to which such
jurisdiction is a party, with respect to payments hereunder or under any other
Loan Document shall deliver to the Borrower (with a copy to the Administrative
Agent), at the time or times prescribed by applicable law or reasonably
requested by the Borrower or the Administrative Agent, such properly completed
and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate of withholding. In
addition, any Lender, if requested by the Borrower or the Administrative Agent,
shall deliver such other documentation prescribed by applicable law or
reasonably requested by the Borrower or the Administrative Agent as will enable
the Borrower or the Administrative Agent to determine whether or not such Lender
is subject to backup withholding or information reporting requirements.

     Without limiting the generality of the foregoing, in the event that the
Borrower is resident for tax purposes in the United States, any Foreign Lender
shall deliver to the Borrower and the Administrative Agent (in such number of
copies as shall be requested by the recipient) on or prior to the date on which
such Foreign Lender becomes a Lender under this Agreement (and from time to time
thereafter upon the request of the Borrower or the Administrative Agent, but
only if such Foreign Lender is legally entitled to do so), whichever of the
following is applicable:

          (i) duly completed copies of Internal Revenue Service Form W-8BEN
     claiming eligibility for benefits of an income tax treaty to which the
     United States is a party,

          (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

          (iii) in the case of a Foreign Lender claiming the benefits of the
     exemption for portfolio interest under section 881(c) of the Code, (x) a
     certificate to the effect that such Foreign Lender is not (A) a "bank"
     within the meaning of section 881(c)(3)(A) of the Code, (B) a "10 percent
     shareholder" of the Borrower within the meaning of section 881(c)(3)(B) of
     the Code, or (C) a "controlled foreign corporation" described in section
     881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue
     Service Form W-8BEN, or

          (iv) any other form prescribed by applicable law as a basis for
     claiming exemption from or a reduction in United States Federal withholding
     tax duly completed


                                       28



     together with such supplementary documentation as may be prescribed by
     applicable law to permit the Borrower to determine the withholding or
     deduction required to be made.

     (f) Treatment of Certain Refunds. If the Administrative Agent or any Lender
determines, in its good faith discretion, that it has received a refund or
credit of any Taxes or Other Taxes as to which it has been indemnified by the
Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section, it shall pay to the Borrower an amount equal to such
refund or credit (but only to the extent of indemnity payments made, or
additional amounts paid, by the Borrower under this Section with respect to the
Taxes or Other Taxes giving rise to such refund or credit), net of all
reasonable out-of-pocket expenses of the Administrative Agent or such Lender, as
the case may be, and without interest (other than any interest paid by the
relevant Governmental Authority with respect to such refund or credit), provided
that the Borrower, upon the request of the Administrative Agent or such Lender,
agrees to repay the amount paid over to the Borrower (plus any penalties,
interest or other charges imposed by the relevant Governmental Authority) to the
Administrative Agent or such Lender in the event the Administrative Agent or
such Lender is required to repay such refund or credit to such Governmental
Authority. This subsection shall not be construed to require the Administrative
Agent or any Lender to make available its tax returns (or any other information
relating to its taxes that it deems confidential) to the Borrower or any other
Person.

     3.02 ILLEGALITY. If any Lender determines in good faith that any Law has
made it unlawful, or that any Governmental Authority has asserted that it is
unlawful, for any Lender or its applicable Lending Office to make, maintain or
fund Eurodollar Rate Loans, or to determine or charge interest rates based upon
the Eurodollar Rate, or any Governmental Authority has imposed material
restrictions on the authority of such Lender to purchase or sell, or to take
deposits of, Dollars in the London interbank market, then, on notice thereof by
such Lender to the Borrower through the Administrative Agent, any obligation of
such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate
Loans to Eurodollar Rate Loans shall be suspended until such Lender in good
faith notifies the Administrative Agent and the Borrower that the circumstances
giving rise to such determination no longer exist. Upon receipt of such notice,
the Borrower shall, upon demand from such Lender (with a copy to the
Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate
Loans of such Lender to Base Rate Loans, either on the last day of the Interest
Period therefor, if such Lender may lawfully continue to maintain such
Eurodollar Rate Loans to such day, or immediately, if such Lender may not
lawfully continue to maintain such Eurodollar Rate Loans. Upon any such
prepayment or conversion, the Borrower shall also pay accrued interest on the
amount so prepaid or converted.

     3.03 INABILITY TO DETERMINE RATES. If the Required Lenders determine that
for any reason in connection with any request for a Eurodollar Rate Loan or a
conversion to or continuation thereof that (a) Dollar deposits are not being
offered to banks in the London interbank eurodollar market for the applicable
amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and
reasonable means do not exist for determining the Eurodollar Base Rate for any
requested Interest Period with respect to a proposed Eurodollar Rate Loan, or
(c) the Eurodollar Base Rate for any requested Interest Period with respect to a
proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to
such Lenders of funding such Loan, the Administrative Agent will promptly so
notify the Borrower and each Lender. Thereafter, the obligation of the Lenders
to make or maintain Eurodollar Rate Loans shall be


                                       29



suspended until the Administrative Agent (upon the instruction of the Required
Lenders) revokes such notice. Upon receipt of such notice, the Borrower may
revoke any pending request for a Borrowing of, conversion to or continuation of
Eurodollar Rate Loans or, failing that, will be deemed to have converted such
request into a request for a Committed Borrowing of Base Rate Loans in the
amount specified therein.

     3.04 INCREASED COSTS.

     (a) Increased Costs Generally. If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit,
     compulsory loan, insurance charge or similar requirement against assets of,
     deposits with or for the account of, or credit extended or participated in
     by, any Lender (except any reserve requirement reflected in the Eurodollar
     Rate);

          (ii) subject any Lender to any tax of any kind whatsoever with respect
     to this Agreement or any Eurodollar Rate Loan made by it, or change the
     basis of taxation of payments to such Lender in respect thereof (except for
     Indemnified Taxes or Other Taxes covered by Section 3.01 and the imposition
     of, or any change in the rate of, any Excluded Tax payable by such Lender);
     or

          (iii) impose on any Lender or the London interbank market any other
     condition, cost or expense affecting this Agreement or Eurodollar Rate
     Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Rate Loan (or of maintaining its
obligation to make any such Loan), or to reduce the amount of any sum received
or receivable by such Lender hereunder (whether of principal, interest or any
other amount) then, upon request of such Lender, the Borrower will pay to such
Lender, as the case may be, such additional amount or amounts as will compensate
such Lender, as the case may be, for such additional costs incurred or reduction
suffered.

     (b) Capital Requirements. If any Lender determines in good faith that any
Change in Law affecting such Lender or any Lending Office of such Lender or such
Lender's holding company, if any, regarding capital requirements has or would
have the effect of reducing the rate of return on such Lender's capital or on
the capital of such Lender's holding company, if any, as a consequence of this
Agreement, the Commitments of such Lender or the Loans made by such Lender
hereunder, to a level below that which such Lender or such Lender's holding
company could have achieved but for such Change in Law (taking into
consideration such Lender's policies and the policies of such Lender's holding
company with respect to capital adequacy), then from time to time the Borrower
will pay to such Lender such additional amount or amounts as will compensate
such Lender or such Lender's holding company for any such reduction suffered.

     (c) Certificates for Reimbursement. A certificate of a Lender setting forth
the amount or amounts necessary to compensate such Lender or its holding
company, as the case may be, as specified in subsection (a) or (b) of this
Section and delivered to the Borrower shall


                                       30


be conclusive absent manifest error. The Borrower shall pay such Lender the
amount shown as due on any such certificate within 10 days after receipt
thereof.

     (d) Delay in Requests. Failure or delay on the part of any Lender to demand
compensation pursuant to the foregoing provisions of this Section shall not
constitute a waiver of such Lender's right to demand such compensation, provided
that the Borrower shall not be required to compensate a Lender pursuant to the
foregoing provisions of this Section for any increased costs incurred or
reductions suffered more than six months prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender's intention to claim compensation therefor
(except that, if the Change in Law giving rise to such increased costs or
reductions is retroactive, then the six-month period referred to above shall be
extended to include the period of retroactive effect thereof).

     3.05 COMPENSATION FOR LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Borrower shall promptly compensate
such Lender for and hold such Lender harmless from any loss (other than loss of
Applicable Rate), cost or expense incurred by it as a result of:

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

     (b) any failure by the Borrower (for a reason other than the failure of
such Lender to make a Loan) to prepay, borrow, continue or convert any Loan
other than a Base Rate Loan on the date or in the amount notified by the
Borrower; or

     (c) any assignment of a Eurodollar Rate Loan on a day other than the last
day of the Interest Period therefor as a result of a request by the Borrower
pursuant to Section 10.13;

excluding any loss of anticipated profits and including any loss or expense
arising from the liquidation or reemployment of funds obtained by it to maintain
such Loan 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 Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under
this Section 3.05, each Lender shall be deemed to have funded each Eurodollar
Rate Loan made by it at the Eurodollar Base Rate used in determining the
Eurodollar Rate for such Loan by a matching deposit or other borrowing in the
London interbank eurodollar market for a comparable amount and for a comparable
period, whether or not such Eurodollar Rate Loan was in fact so funded.

     3.06 MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.

     (a) Designation of a Different Lending Office. If any Lender requests
compensation under Section 3.04, or the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority for the account of
any Lender pursuant to Section 3.01, or if any Lender gives a notice pursuant to
Section 3.02, then such Lender shall use reasonable efforts to designate a
different Lending Office for funding or booking its Loans hereunder or to assign
its


                                       31



rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Lender, such designation or assignment
(i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04,
as the case may be, in the future, or eliminate the need for the notice pursuant
to Section 3.02, as applicable, and (ii) in each case, would not subject such
Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment.

     (b) Replacement of Lenders. If any Lender requests compensation under
Section 3.04 or gives a notice under Section 3.02, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 3.01, the Borrower
may replace such Lender in accordance with Section 10.13.

     3.07 SURVIVAL. All of the Borrower's obligations under this Article III
shall survive termination of the Aggregate Commitments and repayment of all
other Obligations hereunder.

                                  ARTICLE IV.

     Agreement and the other Loan Documents to which the Borrower is a party;

          (iv) such documents and certifications as the Administrative Agent may

     formed, and that the Borrower is validly existing, in good standing and
     qualified to engage in business in the jurisdiction of its organization;

          (v) a favorable opinion of Ropes & Gray LLP, counsel to the Borrower,

such fees, charges and disbursements as shall constitute its reasonable estimate
of such fees, charges and disbursements incurred or to be incurred by it through
the closing proceedings (provided that such estimate shall not thereafter
preclude a final settling of accounts between the Borrower and the
Administrative Agent).

     Without limiting the generality of the provisions of the last paragraph of
Section 9.03, for purposes of determining compliance with the conditions
specified in this Section 4.01, each Lender 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 required thereunder to be consented to or approved
by or acceptable or satisfactory to a Lender unless the Administrative Agent
shall have received notice from such Lender prior to the proposed Closing Date
specifying its objection thereto.

     4.02 CONDITIONS TO THE CREDIT EXTENSION. The obligation of each Lender to

expired and there shall be no governmental or judicial action, actual or
threatened, that has or could have a reasonable likelihood of restraining,
preventing or imposing materially burdensome or materially adverse conditions on

     Each Request for Credit Extension (other than a Committed Loan Notice

                                   ARTICLE V.
                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Administrative Agent and the
Lenders that:

qualified and is licensed and, as applicable, in good standing under the Laws of
each jurisdiction where its ownership, lease or operation of properties or the

case referred to in clause (b)(i) or (c), to the extent that failure to do so
could not reasonably be expected to have a Material Adverse Effect.


                                       34



     5.02 AUTHORIZATION; NO CONTRAVENTION. The execution, delivery and

been duly authorized by all necessary corporate or other organizational action,
and do not and will not (a) contravene the terms of any of the Borrower's
Organization Documents; (b) conflict with or result in any breach or
contravention of, or the creation of any Lien under, or require any payment to
be made under (i) any material Contractual Obligation to which the Borrower is a
party or affecting the Borrower or the properties of the Borrower or any of its
Subsidiaries or (ii) any order, injunction, writ or decree of any Governmental
Authority or any arbitral award to which the Borrower or its property is
subject; or (c) violate any Law.

     5.03 GOVERNMENTAL AUTHORIZATION; OTHER CONSENTS. No approval, consent,
exemption, authorization, or other action by, or notice to, or filing with, any
Governmental Authority or any other Person is necessary or required in
connection with the execution, delivery or performance by, or enforcement
against, the Borrower of this Agreement or any other Loan Document.

     5.04 BINDING EFFECT. This Agreement has been, and each other Loan Document,
when delivered hereunder, will have been, duly executed and delivered by the
Borrower. This Agreement constitutes, and each other Loan Document when so
delivered will constitute, a legal, valid and binding obligation of the
Borrower, enforceable against the Borrower in accordance with its terms, subject
to bankruptcy, insolvency, moratorium and other laws of general application
affecting creditors and general principles of equity.

     5.05 FINANCIAL STATEMENTS; NO MATERIAL ADVERSE EFFECT.

     (a) The Audited Financial Statements (i) were prepared in accordance with
GAAP consistently applied throughout the period covered thereby, except as
otherwise expressly noted therein; (ii) fairly present in all material respects
the financial condition of the Borrower and its Subsidiaries as of the date
thereof and their results of operations for the period covered thereby in
accordance with GAAP consistently applied throughout the period covered thereby,
except as otherwise expressly noted therein; and (iii) show all material
indebtedness and other material liabilities, direct or contingent, of the
Borrower and its Subsidiaries as of the date thereof, including material
liabilities for taxes, material commitments and indebtedness.

     (b) The unaudited consolidated balance sheet of the Borrower and its
Subsidiaries dated March 31, 2007, and the related consolidated statements of
income or operations and cash flows for the fiscal quarter ended on that date
(i) were prepared in accordance with GAAP consistently applied throughout the
period covered thereby, except as otherwise expressly noted therein, and (ii)
fairly present in all material respects the financial condition of the Borrower
and its Subsidiaries as of the date thereof and their results of operations for
the period covered thereby, subject, in the case of clauses (i) and (ii), to the
absence of footnotes and to normal year-end audit adjustments.

     (c) Since the date of the Audited Financial Statements, there has been no
event or circumstance, either individually or in the aggregate, that has had or
could reasonably be expected to have a Material Adverse Effect.


                                       35



     5.06 LITIGATION. There are no actions, suits, proceedings, claims or
disputes pending or, to the knowledge of the Borrower after due and diligent
investigation, threatened or contemplated (to the extent contemplated in
writing), at law, in equity, in arbitration or before any Governmental
Authority, by or against the Borrower or any of its Subsidiaries or against any
of their properties or revenues that (a) purport to affect or pertain to this
Agreement or any other Loan Document, or any of the transactions contemplated
hereby, or (b) except for litigation disclosed in the Borrower's Annual Report
on Form 10-K for the year ended December 31, 2006, either individually or in the
aggregate could reasonably be expected to have a Material Adverse Effect.

     5.07 NO DEFAULT. Neither the Borrower nor any Subsidiary thereof is in
default under or with respect to any material Contractual Obligation that could,
either individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. No Default has occurred and is continuing or would
result from the consummation of the transactions contemplated by this Agreement
or any other Loan Document.

     5.08 OWNERSHIP OF PROPERTY. Each of the Borrower and each Subsidiary has
good record and marketable title in fee simple to, or valid leasehold interests
in, all real property necessary or used in the ordinary conduct of its business,
except for such defects in title as could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. The property of the
Borrower and its Subsidiaries is subject to no Liens, other than Liens permitted
by Section 7.01.

     5.09 ENVIRONMENTAL COMPLIANCE. The Borrower and its Subsidiaries conduct in
the ordinary course of business a review of the effect of existing Environmental
Laws and claims alleging potential liability or responsibility for violation of
any Environmental Law on their respective businesses, operations and properties,
and as a result thereof the Borrower has reasonably concluded that such
Environmental Laws and claims could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

     5.10 USE OF PROCEEDS. The Borrower and its Subsidiaries will have only used
the proceeds of the Credit Extension as permitted by Section 6.11.

     5.11 TAXES. The Borrower and its Subsidiaries have filed all Federal, state
and other material tax returns and reports required to be filed, and have paid
all Federal, state and other material taxes, assessments, fees and other
governmental charges levied or imposed upon them or their properties, income or
assets otherwise due and payable, except those which are being contested in good
faith by appropriate proceedings diligently conducted and for which adequate
reserves have been provided in accordance with GAAP. There is no proposed tax
assessment against the Borrower or any Subsidiary that would reasonably be
expected to have a Material Adverse Effect. Neither the Borrower nor any
Subsidiary thereof is party to any tax sharing agreement.

     5.12 ERISA COMPLIANCE.

     (a) Each Plan is in compliance with the applicable provisions of ERISA, the
Code and other Federal or state Laws, except to the extent failure so to comply
would not reasonably


                                       36



be expected to result in a Material Adverse Effect. Each Plan that is intended
to qualify under Section 401(a) of the Code has received a favorable
determination letter from the IRS or an application for such a letter is
currently being processed by the IRS with respect thereto and, to the best
knowledge of the Borrower, nothing has occurred which would prevent, or cause
the loss of, such qualification. The Borrower and each ERISA Affiliate have made
all required contributions to each Plan subject to Section 412 of the Code, and
no application for a funding waiver or an extension of any amortization period
pursuant to Section 412 of the Code has been made with respect to any Plan.

     (b) There are no pending or, to the best knowledge of the Borrower,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan that could reasonably be expected to have a Material
Adverse Effect. There has been no non-exempt prohibited transaction or violation
of the fiduciary responsibility rules of ERISA or the Code with respect to any
Plan that has resulted or could reasonably be expected to result in a Material
Adverse Effect.

     (c) (i) No ERISA Event has occurred or is reasonably expected to occur,
which has resulted or could reasonably be expected to result in liability of the
Borrower in an aggregate amount in excess of the Threshold Amount; (ii) no
Pension Plan has any Unfunded Pension Liability in excess of the Threshold
Amount; (iii) neither the Borrower nor any ERISA Affiliate has incurred, or
reasonably expects to incur, any liability under Title IV of ERISA with respect
to any Pension Plan (other than premiums due and not delinquent under Section
4007 of ERISA) in excess of the Threshold Amount; (iv) neither the Borrower nor
any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
(and no event has occurred which, with the giving of notice under Section 4219
of ERISA, would result in such liability) under Section 4201 or 4243 of ERISA
with respect to a Multiemployer Plan; and (v) neither the Borrower nor any ERISA
Affiliate has engaged in a transaction that could be subject to Section 4069 or
4212(c) of ERISA.

     5.13 MATERIAL SUBSIDIARIES. The Borrower has no Material Subsidiaries other
than those specifically disclosed in Schedule 5.13 (as supplemented from time to
time), and all of the outstanding Equity Interests in such Subsidiaries have
been validly issued, are fully paid and nonassessable and are owned by the
Borrower in the amounts specified on Schedule 5.13 free and clear of all Liens.

     5.14 MARGIN REGULATIONS; INVESTMENT COMPANY ACT.

     (a) The Borrower is not engaged and will not engage, principally or as one
of its important activities, in the business of purchasing or carrying margin
stock (within the meaning of Regulation U issued by the FRB), or extending
credit for the purpose of purchasing or carrying margin stock in a manner that
would result in a violation of Regulation U of the FRB.

     (b) None of the Borrower, any Person Controlling the Borrower, or any
Subsidiary is or is required to be registered as an "investment company" under
the Investment Company Act of 1940.


                                       37



     5.15 DISCLOSURE. The Borrower has disclosed to the Administrative Agent and
the Lenders all agreements, instruments and corporate or other restrictions to
which it or any of its Subsidiaries is subject, and all other matters known to
it, that, individually or in the aggregate, could reasonably be expected to
result in a Material Adverse Effect. No report, financial statement, certificate
or other information furnished (whether in writing or orally) by or on behalf of
the Borrower to the Administrative Agent or any Lender in connection with the
transactions contemplated hereby and the negotiation of this Agreement or
delivered hereunder or under any other Loan Document (in each case, as modified
or supplemented by other information so furnished) contains any material
misstatement of fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; provided that, with respect to projected financial
information, the Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time.

     5.16 COMPLIANCE WITH LAWS. The Borrower and each Subsidiary thereof is in
compliance in all material respects with the requirements of all Laws (including
the Act defined in Section 10.17) and all orders, writs, injunctions and decrees
applicable to it or to its properties, except in such instances in which (a)
such requirement of Law or order, writ, injunction or decree is being contested
in good faith by appropriate proceedings diligently conducted or (b) the failure
to comply therewith, either individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

     5.17 SOLVENCY. The Borrower and its Subsidiaries taken as a whole are, and
after giving effect to the transactions occurring on the Closing Date will be
Solvent.

     5.18 INTELLECTUAL PROPERTY; LICENSES, ETC. The Borrower and its
Subsidiaries own, or possess the right to use, all of the trademarks, service
marks, trade names, copyrights, patents, patent rights, franchises, licenses and
other intellectual property rights (collectively, "IP Rights") that are
reasonably necessary for the operation of their respective businesses, without
conflict with the rights of any other Person in a manner reasonably likely to
result in a Material Adverse Effect. To the best knowledge of the Borrower, no
slogan or other advertising device, product, process, method, substance, part or
other material now employed, or now contemplated to be employed, by the Borrower
or any Subsidiary infringes upon any rights held by any other Person in a manner
reasonably likely to result in a Material Adverse Effect. No claim or litigation
regarding any of the foregoing is pending or, to the best knowledge of the
Borrower, threatened, which, either individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect.


                                       38



                                   ARTICLE VI.

     So long as any Lender shall have any Commitment hereunder, any Loan or
other Obligation hereunder shall remain unpaid or unsatisfied, the Borrower
shall, and shall (except in the case of the covenants set forth in Sections
6.01, 6.02, and 6.03) cause each Subsidiary to:

GAAP, audited and accompanied by a report and opinion of an independent
certified public accountant of nationally recognized standing reasonably
acceptable to the Required Lenders, which report and opinion shall be prepared
in accordance with generally accepted auditing standards and shall not be
subject to any "going concern" or like qualification or exception or any
qualification or exception as to the scope of such audit; and

     (b) as soon as available, but in any event within 45 days after the end of
each of the first three fiscal quarters of each fiscal year of the Borrower

quarter, and the related consolidated statements of income or operations and
cash flows for such fiscal quarter and for the portion of the Borrower's fiscal

the corresponding fiscal quarter of the previous fiscal year and the

adjustments and the absence of footnotes.

     As to any information contained in materials furnished pursuant to Section
6.02(c), the Borrower shall not be separately required to furnish such
information under clause (a) or (b) above, but the foregoing shall not be in
derogation of the obligation of the Borrower to furnish the information and
materials described in clauses (a) and (b) above at the times specified therein.

     6.02 CERTIFICATES; OTHER INFORMATION. Deliver to the Administrative Agent

     (e) promptly, and in any event within five Business Days after receipt

other operational results of the Borrower or any Subsidiary thereof; and

     (f) promptly, such additional information regarding the business, financial
or corporate affairs of the Borrower or any Subsidiary, or compliance with the
terms of the Loan Documents, as the Administrative Agent or any Lender may from
time to time reasonably request.

     Documents required to be delivered pursuant to Section 6.01(a) or (b) or
Section 6.02(c) (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 10.02; or (ii)
on which such documents are posted on the Borrower's behalf on an Internet or

access (whether a commercial, third-party website or whether sponsored by the
Administrative Agent); provided that: (i) the Borrower shall deliver paper
copies of such documents to the Administrative Agent or any Lender that requests
the Borrower to deliver such paper copies until a written request to cease
delivering paper copies is given by the Administrative Agent or such Lender and
(ii) the Borrower shall notify the Administrative Agent (by telecopier or

Certificates required by Section 6.02(b) to the Administrative Agent. Except for
such Compliance Certificates, the Administrative 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


                                       40



responsibility to monitor compliance by the Borrower with any such request for
delivery, and each Lender shall be solely responsible for requesting delivery to
it or maintaining its copies of such documents.

     The Borrower hereby acknowledges that (a) the Administrative Agent and/or
the Arrangers will make available to the Lenders materials and/or information
provided by or on behalf of the Borrower hereunder (collectively, "Borrower
Materials") by posting the Borrower Materials on IntraLinks or another similar
electronic system (the "Platform") and (b) certain of the Lenders (each, a
"Public Lender") may have personnel who do not wish to receive material
non-public information with respect to the Borrower or its Affiliates, or the
respective securities of any of the foregoing, and who may be engaged in
investment and other market-related activities with respect to such Persons'
securities. The Borrower hereby agrees that (w) all Borrower Materials that are
to be made available to Public Lenders shall be clearly and conspicuously marked
"PUBLIC" which, at a minimum, shall mean that the word "PUBLIC" shall appear
prominently on the first page thereof; (x) by marking Borrower Materials
"PUBLIC," the Borrower shall be deemed to have authorized the Administrative
Agent, the Arranger and the Lenders to treat such Borrower Materials as not
containing any material non-public information with respect to the Borrower or
its securities for purposes of United States Federal and state securities laws
(provided, however, that to the extent such Borrower Materials constitute
Information, they shall be treated as set forth in Section 10.07); (y) all
Borrower Materials marked "PUBLIC" are permitted to be made available through a
portion of the Platform designated "Public Investor;" and (z) the Administrative
Agent and the Arranger shall be entitled to treat any Borrower Materials that
are not marked "PUBLIC" as being suitable only for posting on a portion of the
Platform not designated "Public Investor."

     6.03 NOTICES. Promptly notify the Administrative Agent and each Lender:

     (a) of the occurrence of any Default;

     (b) of any matter that has resulted or could reasonably be expected to
result in a Material Adverse Effect, including such matters arising from (i)
breach or non-performance of, or any default under, a Contractual Obligation of
the Borrower or any Subsidiary; (ii) any dispute, litigation, investigation,
proceeding or suspension between the Borrower or any Subsidiary and any
Governmental Authority; or (iii) the commencement of, or any material
development in, any litigation or proceeding affecting the Borrower or any
Subsidiary, including pursuant to any applicable Environmental Laws;

     (c) of the occurrence of any ERISA Event;

shall be accompanied by a statement of a Responsible Officer of the Borrower
setting forth details of the occurrence referred to therein and stating what
action the Borrower has taken and proposes to take with respect thereto. Each
notice pursuant to Section 6.03(a) shall describe with


                                       41



particularity any and all provisions of this Agreement and any other Loan
Document that have been breached.

     6.04 PAYMENT OF OBLIGATIONS. Pay and discharge as the same shall become due
and payable, all its obligations and liabilities, including (a) all tax
liabilities, assessments and governmental charges or levies upon it or its
properties or assets, unless the same are being contested in good faith by
appropriate proceedings diligently conducted and adequate reserves in accordance
with GAAP are being maintained by the Borrower or such Subsidiary; (b) all
lawful claims which, if unpaid, would by law become a Lien upon its property;
and (c) all Indebtedness, as and when due and payable, but subject to any
subordination provisions contained in any instrument or agreement evidencing
such Indebtedness.

     6.05 PRESERVATION OF EXISTENCE, ETC. (a) Preserve, renew and maintain in

the jurisdiction of its organization except in a transaction permitted by
Section 7.04 or 7.05; (b) take all reasonable action to maintain all rights,
privileges, permits, licenses and franchises necessary or desirable in the
normal conduct of its business, except to the extent that failure to do so could
not reasonably be expected to have a Material Adverse Effect; and (c) preserve
or renew all of its registered patents, trademarks, trade names and service
marks, the non-preservation of which could reasonably be expected to have a
Material Adverse Effect.

     6.06 MAINTENANCE OF PROPERTIES. (a) Maintain, preserve and protect all of
its material properties and equipment necessary in the operation of its business
in good working order and condition, ordinary wear and tear excepted; and (b)
make all necessary repairs thereto and renewals and replacements thereof except
where the failure to do so could not reasonably be expected to have a Material
Adverse Effect.

     6.07 MAINTENANCE OF INSURANCE. Maintain with financially sound and
reputable insurance companies not Affiliates of the Borrower, insurance with
respect to its properties and business against loss or damage of the kinds
customarily insured against by Persons engaged in the same or similar business,
of such types and in such amounts as are customarily carried under similar
circumstances by such other Persons.

     6.08 COMPLIANCE WITH LAWS. Comply in all material respects with the
requirements of all Laws (including Environmental Laws) and all orders, writs,
injunctions and decrees applicable to it or to its business or property, except
in such instances in which (a) such requirement of Law or order, writ,
injunction or decree is being contested in good faith by appropriate proceedings
diligently conducted; or (b) the failure to comply therewith could not
reasonably be expected to have a Material Adverse Effect.

     6.09 BOOKS AND RECORDS. Maintain proper books of record and account, in
which full, true and correct entries in conformity with GAAP consistently
applied shall be made of all financial transactions and matters involving the
assets and business of the Borrower or such Subsidiary, as the case may be.

     6.10 INSPECTION RIGHTS. Permit representatives and independent contractors
of the Administrative Agent and each Lender to visit and inspect any of its
properties, to examine its


                                       42



corporate, financial and operating records, and make copies thereof or abstracts
therefrom, and to discuss its affairs, finances and accounts with its directors,
officers, and independent public accountants, all at such reasonable times
during normal business hours and as often as may be reasonably desired, upon
reasonable advance notice to the Borrower; provided, however, that (a) absent
the existence of an Event of Default, only one such visit or inspection may be
made during any calendar year and (b) when an Event of Default exists the
Administrative Agent or any Lender (or any of their respective representatives
or independent contractors) may do any of the foregoing at the expense of the
Borrower at any time during normal business hours and without advance notice.

     6.11 USE OF PROCEEDS. Use the proceeds of the Credit Extension to pay a
portion of the consideration for the Tender and Offer and to pay related fees
and expenses, corporate purposes not in contravention of any Law or of any Loan
Document and not to purchase or carry margin stock (within the meaning of
Regulation U of the FRB) or to extend credit to others for the purpose of
purchasing or carrying margin stock or to refund indebtedness originally
incurred for such purpose, in each case so as to result in a violation of
Regulation U of the FRB.

                                  ARTICLE VII.
                               NEGATIVE COVENANTS

     So long as any Lender shall have any Commitment hereunder, any Loan or

                                       50



     9.02 RIGHTS AS A LENDER. The Person serving as the Administrative Agent
hereunder shall have the same rights and powers in its capacity as a Lender as
any other Lender and may exercise the same as though it were not the
Administrative Agent and the term "Lender" or "Lenders" shall, unless otherwise
expressly indicated or unless the context otherwise requires, include the Person
serving as the Administrative Agent hereunder in its individual capacity. Such
Person and its Affiliates may accept deposits from, lend money to, act as the
financial advisor or in any other advisory capacity for and generally engage in
any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if such Person were not the Administrative Agent hereunder and
without any duty to account therefor to the Lenders.

     9.03 EXCULPATORY PROVISIONS. The Administrative Agent shall not have any
duties or obligations except those expressly set forth herein and in the other
Loan Documents. Without limiting the generality of the foregoing, the
Administrative Agent:

          (a) shall not be subject to any fiduciary or other implied duties,
     regardless of whether a Default has occurred and is continuing;

          (b) shall not have any duty to take any discretionary action or
     exercise any discretionary powers, except discretionary rights and powers
     expressly contemplated hereby or by the other Loan Documents that the
     Administrative Agent is required to exercise as directed in writing by the
     Required Lenders (or such other number or percentage of the Lenders as
     shall be expressly provided for herein or in the other Loan Documents),
     provided that the Administrative Agent shall not be required to take any
     action that, in its opinion or the opinion of its counsel, may expose the
     Administrative Agent to liability or that is contrary to any Loan Document
     or applicable law; and

          (c) shall not, except as expressly set forth herein and in the other
     Loan Documents, have any duty to disclose, and shall not be liable for the
     failure to disclose, any information relating to the Borrower or any of its
     Affiliates that is communicated to or obtained by the Person serving as the
     Administrative Agent or any of its Affiliates in any capacity.

     The Administrative Agent shall not be liable for any action taken or not
taken by it (i) with the consent or at the request of the Required Lenders (or
such other number or percentage of the Lenders as shall be necessary, or as the
Administrative Agent shall believe in good faith shall be necessary, under the
circumstances as provided in Sections 10.01 and 8.02) or (ii) in the absence of
its own gross negligence or willful misconduct. The Administrative Agent shall
be deemed not to have knowledge of any Default unless and until notice
describing such Default is given to the Administrative Agent by the Borrower or
a Lender.

     The Administrative Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with this Agreement or any other Loan Document, (ii) the
contents of any certificate, report or other document delivered hereunder or
thereunder or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein or therein or the occurrence of any Default, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan
Document or any other


                                       51



agreement, instrument or document or (v) the satisfaction of any condition set
forth in Article IV or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent.

     9.04 RELIANCE BY ADMINISTRATIVE AGENT.

     The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing (including any electronic
message, Internet or intranet website posting or other distribution) believed by
it to be genuine and to have been signed, sent or otherwise authenticated by the
proper Person. The Administrative Agent also may rely upon any statement made to
it orally or by telephone and believed by it to have been made by the proper
Person, and shall not incur any liability for relying thereon. In determining
compliance with any condition hereunder to the making of a Loan that by its
terms must be fulfilled to the satisfaction of a Lender, the Administrative
Agent may presume that such condition is satisfactory to such Lender unless the
Administrative Agent shall have received notice to the contrary from such Lender
prior to the making of such Loan. The Administrative Agent may consult with
legal counsel (who may be counsel for the Borrower), independent accountants and
other experts selected by it, and shall not be liable for any action taken or
not taken by it in accordance with the advice of any such counsel, accountants
or experts.

     9.05 DELEGATION OF DUTIES. The Administrative Agent may perform any and all
of its duties and exercise its rights and powers hereunder or under any other
Loan Document by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may
perform any and all of its duties and exercise its rights and powers by or
through their respective Related Parties. The exculpatory provisions of this
Article shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent.

     9.06 RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative Agent may at
any time give notice of its resignation to the Lenders and the Borrower. Upon
receipt of any such notice of resignation, the Required Lenders shall have the
right, with approval of the Borrower, which approval shall not be unreasonably
withheld or delayed and which shall not be required if an Event of Default has
occurred and is then continuing, to appoint a successor, which shall be a bank
with an office in the United States, or an Affiliate of any such bank with an
office in the United States. If no such successor shall have been so appointed
by the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of its resignation, then
the retiring Administrative Agent may on behalf of the Lenders, appoint a
successor Administrative Agent meeting the qualifications set forth above;
provided that if the Administrative Agent shall notify the Borrower and the
Lenders that no qualifying Person has accepted such appointment, then such
resignation shall nonetheless become effective in accordance with such notice
and (1) the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder and under the other Loan Documents and (2) all
payments, communications and determinations provided to be made by, to or
through the Administrative Agent shall instead be made by or to each Lender
directly, until such time as the Required Lenders appoint a successor
Administrative Agent as provided for above in this


                                       52



Section. Upon the acceptance of a successor's appointment as Administrative
Agent hereunder, such successor shall succeed to and become vested with all of
the rights, powers, privileges and duties of the retiring (or retired)
Administrative Agent, and the retiring Administrative Agent shall be discharged
from all of its duties and obligations hereunder or under the other Loan
Documents (if not already discharged therefrom as provided above in this
Section). The fees payable by the Borrower to a successor Administrative Agent
shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After the retiring Administrative
Agent's resignation hereunder and under the other Loan Documents, the provisions
of this Article and Section 10.04 shall continue in effect for the benefit of
such retiring Administrative Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them

     9.07 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each Lender
acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender or any of their Related Parties and
based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender or any of their Related Parties and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement, any other Loan Document or any related
agreement or any document furnished hereunder or thereunder.

Letter, no amendment or waiver of any provision of this Agreement, and no
consent to any departure by the Borrower therefrom, shall be effective unless in
writing signed by the Required Lenders and the Borrower, and acknowledged by the
Administrative Agent, and each such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given; provided,
however, that no such amendment, waiver or consent shall:

     (a) waive any condition set forth in Section 4.01(a) without the written

                                       53



hereunder or under any other Loan Document (other than any mandatory prepayment
under Section 2.05(b)) without the written consent of each Lender directly
affected thereby;

     (d) reduce the principal of, or the rate of interest specified herein on,
any Loan, or (subject to clause (iv) of the second proviso to this Section
10.01) any fees or other amounts payable hereunder or under any other Loan
Document without the written consent of each Lender directly affected thereby;
provided, however, that only the consent of the Required Lenders 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;

     (e) change Section 2.13 or Section 8.03 in a manner that would alter the
pro rata sharing of payments required thereby without the written consent of

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Lenders
required above, affect the rights or duties of the Administrative Agent under
this Agreement or any other Loan Document and (ii) until completion of
"Successful Syndication" (as defined in the Engagement Letter), any such
amendment, waiver or consent shall also require the consent of the Syndication
Agent. Notwithstanding anything to the contrary herein, no Defaulting Lender
shall have any right to approve or disapprove any amendment, waiver or consent
hereunder, except that the Commitment of such Lender may not be increased or
extended without the consent of such Lender.

     10.02 NOTICES; EFFECTIVENESS; ELECTRONIC COMMUNICATION.

     (a) Notices Generally. Except in the case of notices and other

                                       54



recipient). Notices delivered through electronic communications to the extent
provided in subsection (b) below, shall be effective as provided in such
subsection (b).

     (b) Electronic Communications. Notices and other communications to the
Lenders hereunder may be delivered or furnished by electronic communication
(including e-mail and Internet or intranet websites) pursuant to procedures
approved by the Administrative Agent, provided that the foregoing shall not
apply to notices to any Lender pursuant to Article II if such Lender has
notified the Administrative Agent that it is incapable of receiving notices
under such Article by electronic communication. The Administrative Agent or the
Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to
procedures approved by it, provided that approval of such procedures may be
limited to particular notices or communications.

     Unless the Administrative Agent otherwise prescribes, (i) notices and other
communications sent to an e-mail address shall be deemed received upon the
sender's receipt of an acknowledgement from the intended recipient (such as by
the "return receipt requested" function, as available, return e-mail or other
written acknowledgement), provided that if such notice or other communication is
not sent during the normal business hours of the recipient, such notice or
communication shall be deemed to have been sent at the opening of business on
the next business day for the recipient, and (ii) notices or communications
posted to an Internet or intranet website shall be deemed received upon the
deemed receipt by the intended recipient at its e-mail address as described in
the foregoing clause (i) of notification that such notice or communication is

     (c) The Platform. THE PLATFORM IS PROVIDED "AS IS" AND "AS AVAILABLE." THE
AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF
THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM
LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF
ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD
PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT
PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. In no event
shall the Administrative Agent or any of its Related Parties (collectively, the
"Agent Parties") have any liability to the Borrower, any Lender or any other
Person for losses, claims, damages, liabilities or expenses of any kind (whether
in tort, contract or otherwise) arising out of the Borrower's or the
Administrative Agent's transmission of Borrower Materials through the Internet,
except to the extent that such losses, claims, damages, liabilities or expenses
are determined by a court of competent jurisdiction by a final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
such Agent Party; provided, however, that in no event shall any Agent Party have
any liability to the Borrower, any Lender or any other Person for indirect,
special, incidental, consequential or punitive damages (as opposed to direct or
actual damages).

     (d) Change of Address, Etc. Each of the Borrower and the Administrative
Agent may change its address, telecopier or telephone number for notices and
other communications hereunder by notice to the other parties hereto. Each other
Lender may change its address,


                                       55



telecopier or telephone number for notices and other communications hereunder by
notice to the Borrower and the Administrative Agent. In addition, each Lender
agrees to notify the Administrative Agent from time to time to ensure that the
Administrative Agent has on record (i) an effective address, contact name,
telephone number, telecopier number and electronic mail address to which notices
and other communications may be sent and (ii) accurate wire instructions for
such Lender. Furthermore, each Public Lender agrees to cause at least one
individual at or on behalf of such Public Lender to at all times have selected
the "Private Side Information" or similar designation on the content declaration
screen of the Platform in order to enable such Public Lender or its delegate, in
accordance with such Public Lender's compliance procedures and applicable Law,
including United States Federal and state securities Laws, to make reference to
Borrower Materials that are not made available through the "Public Side
Information" portion of the Platform and that may contain material non-public
information with respect to the Borrower or its securities for purposes of
United States Federal or state securities laws.

     (e) Reliance by Administrative Agent and Lenders. The Administrative Agent
and the Lenders shall be entitled to rely and act upon any notices (including
telephonic Committed Loan Notices) purportedly given by or on behalf of the
Borrower even if (i) such notices were not made in a manner specified herein,
were incomplete or were not preceded or followed by any other form of notice
specified herein, or (ii) the terms thereof, as understood by the recipient,
varied from any confirmation thereof. The Borrower shall indemnify the
Administrative Agent, each Lender and the Related Parties of each of them from
all losses, costs, expenses and liabilities resulting from the reliance by such
Person on each notice purportedly given by or on behalf of the Borrower. All
telephonic notices to and other telephonic communications with the
Administrative Agent may be recorded by the Administrative Agent, and each of
the parties hereto hereby consents to such recording.

     10.03 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or the
Administrative Agent to exercise, and no delay by any such Person in exercising,
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. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

     10.04 EXPENSES; INDEMNITY; DAMAGE WAIVER.

     (a) Costs and Expenses. The Borrower shall pay (i) all reasonable
out-of-pocket expenses incurred by the Arrangers, the Administrative Agent, the
Syndication Agent and their respective Affiliates (including the reasonable
fees, charges and disbursements of counsel for the Administrative Agent), in
connection with the syndication of the credit facilities provided for herein,
the preparation, negotiation, execution, delivery and administration of this
Agreement and the other Loan Documents or any amendments, modifications or
waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), and (ii) all reasonable
out-of-pocket expenses incurred by the Administrative Agent or any Lender
(including the reasonable fees, charges and disbursements of any counsel for the
Administrative Agent and one additional counsel for all Lenders other than the


                                       56



Administrative Agent, in connection with the enforcement or protection of its
rights (A) in connection with this Agreement and the other Loan Documents,
including its rights under this Section, or (B) in connection with the Loans
made hereunder, including all such out-of-pocket expenses incurred during any
workout, restructuring or negotiations in respect of such Loans or Letters of
Credit.

     (b) Indemnification by the Borrower. The Borrower shall indemnify each
Arranger, the Administrative Agent (and any sub-agent thereof), the Syndication
Agent, each Lender and each Related Party of any of the foregoing Persons (each
such Person being called an "Indemnitee") against, and hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related
reasonable expenses (including the reasonable fees, charges and disbursements of
any counsel for any Indemnitee), incurred by any Indemnitee or asserted against
any Indemnitee by any third party or by the Borrower arising out of, in
connection with, or as a result of (i) the execution or delivery of this
Agreement, any other Loan Document or any agreement or instrument contemplated
hereby or thereby, the performance by the parties hereto of their respective
obligations hereunder or thereunder, the consummation of the transactions
contemplated hereby or thereby, or, in the case of the Administrative Agent (and
any sub-agent thereof) and its Related Parties only, the administration of this
Agreement and the other Loan Documents, (ii) any Loan or the use or proposed use
of the proceeds therefrom, (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property owned or operated by the Borrower or
any of its Subsidiaries, or any Environmental Liability related in any way to
the Borrower or any of its Subsidiaries, or (iv) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory, whether brought by a third
party or by the Borrower, and regardless of whether any Indemnitee is a party
thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the bad faith, gross
negligence or willful misconduct of such Indemnitee or its Related Parties in
performing services in connection with this Agreement or (y) result from a claim
brought by the Borrower against an Indemnitee for material breach of such
Indemnitee's obligations hereunder or under any other Loan Document, if the
Borrower has obtained a final and nonappealable judgment in its favor on such
claim as determined by a court of competent jurisdiction.

     (c) Reimbursement by Lenders. To the extent that the Borrower for any
reason fails to indefeasibly pay any amount required under subsection (a) or (b)
of this Section to be paid by it to the Administrative Agent (or any sub-agent
thereof) or any Related Party thereof, each Lender severally agrees to pay to
the Administrative Agent (or any such sub-agent) or such Related Party, as the
case may be, such Lender's Applicable Percentage (determined as of the time that
the applicable unreimbursed expense or indemnity payment is sought) of such
unpaid amount, provided that the unreimbursed expense or indemnified loss,
claim, damage, liability or related expense, as the case may be, was incurred by
or asserted against the Administrative Agent (or any such sub-agent) in its
capacity as such, or against any Related Party of any of the foregoing acting
for the Administrative Agent (or any such sub-agent) in connection with such
capacity. The obligations of the Lenders under this subsection (c) are subject
to the provisions of Section 2.12(d).


                                       57



     (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted
by applicable law, the Borrower shall not assert, and hereby waives, any claim
against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages)
arising out of, in connection with, or as a result of, this Agreement, any other
Loan Document or any agreement or instrument contemplated hereby, the
transactions contemplated hereby or thereby, any Loan or the use of the proceeds
thereof. No Indemnitee referred to in subsection (b) above shall be liable for
any damages arising from the use by unintended recipients of any information or
other materials distributed to such unintended recipients by such Indemnitee
through telecommunications, electronic or other information transmission systems
in connection with this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby other than for direct or actual
damages resulting from the gross negligence or willful misconduct of such
Indemnitee as determined by a final and nonappealable judgment of a court of
competent jurisdiction.

     (e) Payments. All amounts due under this Section shall be payable not later
than ten Business Days after demand therefor.

     (f) Survival. The agreements in this Section shall survive the resignation
of the Administrative Agent, the replacement of any Lender, the termination of
the Aggregate Commitments and the repayment, satisfaction or discharge of all
the other Obligations.

     10.05 PAYMENTS SET ASIDE. To the extent that any payment by or on behalf of
the Borrower is made to the Administrative Agent or any Lender, or the
Administrative Agent or any Lender exercises its right of setoff, and such
payment or the proceeds of such setoff or any part thereof is subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent
or such Lender in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any proceeding under any Debtor Relief Law 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 setoff had
not occurred, and (b) each Lender severally agrees to pay to the Administrative
Agent upon demand its applicable share (without duplication) of any amount so
recovered from or repaid by the Administrative 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. The obligations of
the Lenders under clause (b) of the preceding sentence shall survive the payment
in full of the Obligations and the termination of this Agreement.

     10.06 SUCCESSORS AND ASSIGNS.

     (a) Successors and Assigns Generally. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that the Borrower may
not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of the Administrative Agent and each Lender
and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an assignee in accordance with the provisions of
subsection (b) of this Section, (ii) by way of participation in accordance with
the provisions of subsection (d) of this Section, or (iii) by way of pledge or
assignment of a security interest subject to the restrictions of


                                       58



subsection (f) of this Section (and any other attempted assignment or transfer
by any party hereto shall be null and void). Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than
the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in subsection (d) of this Section and, to
the extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent and the Lenders) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

     (b) Assignments by Lenders. Any Lender may at any time assign to one or
more assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment and the Loans at the
time owing to it); provided that any such assignment shall be subject to the
following conditions:

          (i) Minimum Amounts.

               (A) in the case of an assignment of the entire remaining amount
          of the assigning Lender's Commitment and the Loans at the time owing
          to it or in the case of an assignment to a Lender, an Affiliate of a
          Lender or an Approved Fund, no minimum amount need be assigned; and

               (B) in any case not described in subsection (b)(i)(A) of this
          Section, the aggregate amount of the Commitment (which for this
          purpose includes Loans outstanding thereunder) or, if the Commitment
          is not then in effect, the principal outstanding balance of the Loans
          of the assigning Lender subject to each such assignment, determined as
          of the date the Assignment and Assumption with respect to such
          assignment is delivered to the Administrative Agent or, if "Trade
          Date" is specified in the Assignment and Assumption, as of the Trade
          Date, shall not be less than $5,000,000 unless each of the
          Administrative Agent and, so long as no Event of Default has occurred
          and is continuing, the Borrower otherwise consents (each such consent
          not to be unreasonably withheld or delayed); provided, however, that
          concurrent assignments to members of an Assignee Group and concurrent
          assignments from members of an Assignee Group to a single Eligible
          Assignee (or to an Eligible Assignee and members of its Assignee
          Group) will be treated as a single assignment for purposes of
          determining whether such minimum amount has been met.

          (ii) Proportionate Amounts. Each partial assignment shall be made as
     an assignment of a proportionate part of all the assigning Lender's rights
     and obligations under this Agreement with respect to the Loans or the
     Commitment assigned;

          (iii) Required Consents. No consent shall be required for any
     assignment except to the extent required by subsection (b)(i)(B) of this
     Section and, in addition:

               (A) the consent of the Borrower (such consent not to be
          unreasonably withheld or delayed) shall be required unless (1) an
          Event of Default under Section 8.01(a), 8.01(f) or 8.01(g) has
          occurred and is continuing at the time of such assignment, (2) such
          assignment is to a Lender, an Affiliate of a Lender or


                                       59



          an Approved Fund or (3) if such assignment is reasonably determined by
          the Administrative Agent and the Syndication Agent to be necessary to
          achieve a "Successful Syndication" (as defined in the Engagement
          Letter); and

               (B) the consent of the Administrative Agent (such consent not to
          be unreasonably withheld or delayed) shall be required if such
          assignment is to a Person that is not a Lender, an Affiliate of a
          Lender or an Approved Fund with respect to such Lender.

          (iv) Assignment and Assumption. The parties to each assignment shall
     execute and deliver to the Administrative Agent an Assignment and
     Assumption, together with a processing and recordation fee in the amount of
     $3,500; provided, however, that the Administrative Agent may, in its sole
     discretion, elect to waive such processing and recordation fee in the case
     of any assignment. The assignee, if it is not a Lender, shall deliver to
     the Administrative Agent an Administrative Questionnaire.

          (v) No Assignment to Borrower. No such assignment shall be made to the
     Borrower or any of the Borrower's Affiliates or Subsidiaries.

          (vi) No Assignment to Natural Persons. No such assignment shall be
     made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant
to subsection (c) of this Section, from and after the effective date specified
in each Assignment and Assumption, the assignee thereunder shall be a party to
this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto) but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04 with
respect to facts and circumstances occurring prior to the effective date of such
assignment. Upon request, the Borrower (at its expense) shall execute and
deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
subsection shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
subsection (d) of this Section.

     (c) Register. The Administrative Agent, acting solely for this purpose as
an agent of the Borrower, shall maintain at the Administrative Agent's Office a
copy of each Assignment and Assumption delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The


                                       60



Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

     (d) Participations. Any Lender may at any time, without the consent of, or
notice to, the Borrower or the Administrative Agent, sell participations to any
Person (other than a natural person or the Borrower or any of the Borrower's
Affiliates or Subsidiaries) (each, a "Participant") in all or a portion of such
Lender's rights and/or obligations under this Agreement (including all or a
portion of its Commitment and/or the Loans; provided that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrower, the Administrative Agent and the
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement.

     Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, waiver or other modification described in the first proviso to
Section 10.01 that affects such Participant. Subject to subsection (e) of this
Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to subsection (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 10.08 as though it were a Lender, provided
such Participant agrees to be subject to Section 2.13 as though it were a
Lender.

     (e) Limitations upon Participant Rights. A Participant shall not be
entitled to receive any greater payment under Section 3.01 or 3.04 than the
applicable Lender 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 Lender if it were a Lender shall not be
entitled to the benefits of Section 3.01 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 3.01(e) as though it were a
Lender.

     (f) Certain Pledges. Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement (including
under its Note, if any) to secure obligations of such Lender, including any
pledge or assignment to secure obligations to a Federal Reserve Bank; provided
that no such pledge or assignment shall release such Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

     (g) Electronic Execution of Assignments. The words "execution," "signed,"
"signature," and words of like import in any Assignment and Assumption shall be
deemed to include electronic signatures or the keeping of records in electronic
form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in
any applicable law, including the Federal Electronic Signatures in Global and
National Commerce


                                       61



Act, the New York State Electronic Signatures and Records Act, or any other
similar state laws based on the Uniform Electronic Transactions Act.

     10.07 TREATMENT OF CERTAIN INFORMATION; CONFIDENTIALITY. Each of the
Arrangers, the Administrative Agent, the Syndication Agent and the Lenders
agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its Affiliates and to its and
its Affiliates' respective partners, directors, officers, employees, agents,
advisors and representatives (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority purporting to have jurisdiction
over it (including any self-regulatory authority, such as the National
Association of Insurance Commissioners), (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party hereto, (e) in connection with the exercise of any remedies
hereunder or under any other Loan Document or any action or proceeding relating
to this Agreement or any other Loan Document or the enforcement of rights
hereunder or thereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement or (ii) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
the Borrower and its obligations, (g) with the consent of the Borrower or (h) to
the extent such Information (x) becomes publicly available other than as a
result of a breach of this Section or (y) becomes available to any Arranger, the
Administrative Agent, the Syndication Agent, any Lender or any of their
respective Affiliates on a nonconfidential basis from a source other than the
Borrower.

     For purposes of this Section, "Information" means all information received
from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary
or any of their respective businesses, other than any such information that is
available to any Arranger, the Administrative Agent, the Syndication Agent or
any Lender on a nonconfidential basis prior to disclosure by the Borrower or any
Subsidiary, provided that, in the case of information received from the Borrower
or any Subsidiary after the date hereof, such information is clearly identified
at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

     Each of the Arrangers, the Administrative Agent, the Syndication Agent and
the Lenders acknowledges that (a) the Information may include material
non-public information concerning the Borrower or a Subsidiary, as the case may
be, (b) it has developed compliance procedures regarding the use of material
non-public information and (c) it will handle such material non-public
information in accordance with applicable Law, including United States Federal
and state securities Laws.

     10.08 RIGHT OF SETOFF. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any
time and from time to time, to the fullest extent permitted by applicable law,
to set off and apply any and all deposits (general or special, time or demand,
provisional or final, in whatever currency) at any time held and other


                                       62



obligations (in whatever currency) at any time owing by such Lender or any such
Affiliate to or for the credit or the account of the Borrower against any and
all of the obligations of the Borrower now or hereafter existing under this
Agreement or any other Loan Document to such Lender, irrespective of whether or
not such Lender shall have made any demand under this Agreement or any other
Loan Document and although such obligations of the Borrower may be contingent or
unmatured or are owed to a branch or office of such Lender different from the
branch or office holding such deposit or obligated on such indebtedness. The
rights of each Lender and its Affiliates under this Section are in addition to
other rights and remedies (including other rights of setoff) that such Lender or
its Affiliates may have. Each Lender agrees to notify the Borrower and the
Administrative Agent promptly after any such setoff and application, provided
that the failure to give such notice shall not affect the validity of such
setoff and application.

     10.09 INTEREST RATE LIMITATION. Notwithstanding anything to the contrary
contained in any Loan Document, the interest paid or agreed to be paid under the
Loan Documents shall not exceed the maximum rate of non-usurious interest
permitted by applicable Law (the "Maximum Rate"). If the Administrative Agent or
any Lender shall receive interest in an amount that exceeds the Maximum Rate,
the excess interest shall be applied to the principal of the Loans or, if it
exceeds such unpaid principal, refunded to the Borrower. In determining whether
the interest contracted for, charged, or received by the Administrative Agent or
a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by
applicable Law, (a) characterize any payment that is not principal as an
expense, fee, or premium rather than interest, (b) exclude voluntary prepayments
and the effects thereof, and (c) amortize, prorate, allocate, and spread in
equal or unequal parts the total amount of interest throughout the contemplated
term of the Obligations hereunder.

     10.10 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement may be
executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and the other
Loan Documents constitute the entire contract among the parties relating to the
subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof that, when taken together, bear the
signatures of each of the other parties hereto. Delivery of an executed
counterpart of a signature page of this Agreement by telecopy shall be effective
as delivery of a manually executed counterpart of this Agreement.

     10.11 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default at the time of any Credit Extension, and shall continue in full
force and effect as long as any Loan or any other Obligation hereunder shall
remain unpaid or unsatisfied.


                                       63



     10.12 SEVERABILITY. If any provision of this Agreement or the other Loan
Documents is held to be illegal, invalid or unenforceable, (a) the legality,
validity and enforceability of the remaining provisions of this Agreement and
the other Loan Documents shall not be affected or impaired thereby and (b) the
parties shall endeavor in good faith negotiations to replace the illegal,
invalid or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     10.13 REPLACEMENT OF LENDERS. If any Lender requests compensation under
Section 3.04, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.01, or if any Lender gives a notice under Section 3.02, or if any
Lender does not consent to a proposed amendment, waiver or other modification of
any Loan Agreement requiring consent of all of the Lenders and which is
consented to by the Required Lenders, or if any Lender is a Defaulting Lender,
then the Borrower may, at its sole expense and effort, upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in, and consents required by, Section 10.06), all of its interests, rights and
obligations under this Agreement and the related Loan Documents to an assignee
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment), provided that:

     (a) the Borrower shall have paid to the Administrative Agent the assignment
fee specified in Section 10.06(b);

     (b) such Lender shall have received payment of an amount equal to the
outstanding principal of its Loans, accrued interest thereon, accrued fees and
all other amounts payable to it hereunder and under the other Loan Documents
(including any amounts under Section 3.05) from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts);

     (c) in the case of any such assignment resulting from a claim for
compensation under Section 3.04 or payments required to be made pursuant to
Section 3.01, such assignment will result in a reduction in such compensation or
payments thereafter; and

     (d) such assignment does not conflict with applicable Laws.

     A Lender shall not be required to make any such assignment or delegation
if, prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation
cease to apply.

     10.14 GOVERNING LAW; JURISDICTION; ETC.

     (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK

     (b) SUBMISSION TO JURISDICTION. THE BORROWER IRREVOCABLY AND
UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE


                                       64

IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH
ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT
OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT.
EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR
PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY

AGREEMENT OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE
ADMINISTRATIVE AGENT OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE
BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

     (c) WAIVER OF VENUE. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW
OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT
REFERRED TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE
DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING
IN ANY SUCH COURT.

     (d) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE
OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 10.02. NOTHING IN THIS
AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY
OTHER MANNER PERMITTED BY APPLICABLE LAW.

     10.15 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS


                                       65



BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     10.16 NO ADVISORY OR FIDUCIARY RESPONSIBILITY. In connection with all

Document), the Borrower acknowledges and agrees that: (i) (A) the arranging and
