    AMOUNTS
AND TERMS OF THE ADVANCES

     

    Section
2.01 The
Advances.  Each Bank severally agrees, on the terms and
conditions hereinafter set forth, to make Advances in Dollars to the Borrower
from time to time on any Business Day during the Availability Period in an
aggregate amount not to exceed such Bank's Unused Commitment at such time; provided that no
Advance shall be required to be made, except as a part of a Borrowing that is in
an aggregate amount not less than $5,000,000 and in an integral multiple of
$1,000,000, and each Borrowing shall consist of Advances of the same Type made
on the same day by the Banks ratably according to their respective
Commitments.  Within the limits of each Bank's Unused Commitment in
effect from time to time, the Borrower may borrow, prepay pursuant to Section
2.09 and reborrow under this Section 2.01.  The Borrower agrees to
give a Notice of Borrowing in accordance with Section 2.02(a) as to each
Advance.

     

    Section
2.02  Making the
Advances.  (a) Each Borrowing
shall be made on notice in the form of Exhibit B (a "Notice of
Borrowing"), given not later than 11:00 A.M. (New York City time) (i) on
the date of a proposed Borrowing comprised of Base Rate Advances and (ii) on the
third Business Day prior to the date of a proposed Borrowing comprised of
Eurodollar Rate Advances, by the Borrower to the Agent, which shall give to each
Bank prompt notice thereof by facsimile.  Each Notice of Borrowing
shall be consistent with the requirements of Section 2.01 and shall be by
facsimile, confirmed immediately in writing, in substantially the form of
Exhibit B, specifying therein the requested (i) date of such Borrowing, (ii)
Type of Advances comprising such Borrowing, (iii) aggregate amount of such
Borrowing, and (iv) if such Borrowing is to be comprised of Eurodollar Rate
Advances, the initial Interest Period for each such Advance.  Each
Bank shall, before 2:00 p.m. (New York City time) on the date of such Borrowing,
make available for the account of its Applicable Lending Office to the Agent at
its address referred to in Section 8.02, in same day funds, such Bank's ratable
portion of such Borrowing.  After the Agent's receipt of such funds,
the Agent will make such funds available to the Borrower at the Agent's
aforesaid address; provided that the Agent shall not be required to make such
funds available if the applicable conditions set forth in Article III have not
been fulfilled.

     

    (b) Notwithstanding
any other provision in this Agreement, at no time on or prior to the Commitment
Termination Date shall there be more than ten Borrowings outstanding; provided that for
purposes of the limitation set forth in this sentence, all Borrowings consisting
of Base Rate Advances shall constitute a single Borrowing.

     

    (c) Each
Notice of Borrowing shall be irrevocable and binding on the
Borrower.  In the case of any Borrowing that the related Notice of
Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower
shall indemnify each Bank against any loss, cost or expense incurred by such
Bank as a result of any failure to fulfill on or before the date specified in
such Notice of Borrowing for such Borrowing the applicable conditions set forth
in Article III, including, without limitation, any loss (excluding loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Bank to fund the
Advance to be made by such Bank as part of such Borrowing when such Advance, as
a result of such failure, is not made on such date.

     

    (d) Unless
the Agent shall have received notice from a Bank prior to the time of any
Borrowing that such Bank will not make available to the Agent such Bank's
ratable portion of such Borrowing, the Agent may assume that such Bank has made
such portion available to the Agent on the date of such Borrowing in accordance
with subsection (a) of this Section 2.02 and the Agent may, in reliance upon
such assumption, make available to the Borrower on such date a corresponding
amount.  If

     

    
       

      
        12

        
          

        

      

       

    

    and to
the extent that such Bank shall not have so made such ratable portion available
to the Agent, such Bank and the Borrower severally agree to repay to the Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower until
the date such amount is repaid to the Agent, at (i) in the case of the Borrower,
the interest rate applicable at the time to Advances comprising such Borrowing
and (ii) in the case of such Bank, the Federal Funds Rate.  If such
Bank shall repay to the Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Advance as part of such Borrowing for all
purposes.

     

    (e) The
failure of any Bank to make the Advance to be made by it as part of any
Borrowing shall not relieve any other Bank of its obligation, if any, hereunder
to make its Advance on the date of such Borrowing, but no Bank shall be
responsible for the failure of any other Bank to make the Advance to be made by
such other Bank on the date of any Borrowing.

     

    Section
2.03 Fees.  (a)  Facility
Fees.  The Borrower agrees to pay to the Agent for the account
of each Bank a facility fee through the Commitment Termination Date on the

any of the Commitments shall be permanent.

of the Borrower or the issuance or incurrence of any debt securities (excluding
commercial paper and advances under the Existing Revolving Facility) of the
Borrower in an aggregate amount equal to such Net Securities Proceeds. The
amount of any prepayments required pursuant to this clause (i) of Section
2.09(b) shall be applied, first, to the prepayment of
outstanding Advances under this Facility, accompanied by a permanent reduction
of the Commitments in an amount equal to the amount of the Advances so prepaid
and, second, to the
extent no Advances are outstanding on the date of any required prepayment, to
the permanent reduction of the Commitments.

     

    (ii)           Application of Prepayments
to Base Rate Advances and Eurodollar Rate Advances. Considering Advances
being prepaid separately, any prepayment thereof shall be applied first to Base
Rate Advances to the full extent thereof before
application to Eurodollar Rate Advances. The Borrower shall bear all costs
related to the prepayment of a Eurodollar Rate Advance prior to the last day of
any Interest Period in accordance with Section 8.06(b).

     

    Section
2.10 Payments and
Computations.  (a)  The
Borrower shall make each payment hereunder and under the Notes not later than
11:00 A.M. (New York City time) on the day when due in Dollars to the Agent
(except that payments under Section 2.07 shall be paid directly to the Bank
entitled thereto) at Two Penns Way, Suite 200, New Castle, Delaware 19720, in
same day funds.  The Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal, interest or
Facility Fees ratably (except amounts payable pursuant to Section 2.11, Section
2.12 or 2.16 and except that (i) any Bank may receive less than its ratable
share of interest to the extent Section 8.06 is applicable to it and (ii) if, in
respect of any Change in Control, not all Banks are Exercising Banks, then
payments due from the Borrower pursuant to Section 2.18 shall be
distributed ratably among all such Exercising Banks (and not to those Banks that
are not Exercising Banks)) to the Banks for the account of their respective
Applicable Lending Offices, and like funds relating to the payment of any other
amount payable to any Bank to such Bank for the account of its Applicable
Lending Office, in each case to be applied in accordance with the terms of this
Agreement.  Upon its acceptance of an Assignment and Acceptance and
recording of the information contained therein in the Register pursuant to
Section 8.08(c), from and after the effective date specified in such Assignment
and Acceptance, the Agent shall make all payments hereunder and under the Notes
in respect of the interest assigned thereby to the Bank assignee thereunder, and
the parties to such Assignment and Acceptance shall make all appropriate
adjustments in such payments for periods prior to such effective date directly
between themselves.  At the time of each payment of any principal of
or interest on any Borrowing to the Agent, the Borrower shall notify the Agent
of the Borrowing to which such payment shall apply.  In the absence of
such notice the Agent may specify the Borrowing to which such payment shall
apply.

     

    (b) All
computations of interest based on the Base Rate (except during such times as the
Base Rate is determined pursuant to clause (b) or (c) of the definition thereof)
and of Facility Fees shall be made by the Agent on the basis of a year of 365 or
366 days, as the case may be, and all computations of interest based on the
Eurodollar Rate, the Federal Funds Rate or, during such times as the Base Rate
is determined pursuant to clause (b) or (c) of the definition thereof, the Base
Rate shall be made by the Agent, on  the basis of  a year of
360 days, in  each case for  the actual number of days
(including the first

     

    
       

      
        16

        
          

        

      

       

    

    day but
excluding the last day) occurring in the period for which such interest or fees
are payable.  Each determination by the Agent of an interest rate
hereunder shall be conclusive and binding for all purposes, absent manifest
error.

     

    (c) Whenever
any payment hereunder or under the Notes shall be stated to be due on a day
other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of payments of interest and Facility Fees, as the case may be; provided, however, if such
extension would cause payment of interest on or principal of Eurodollar Rate
Advances to be made in the next following calendar month, such payment shall be
made on the next preceding Business Day.

     

    (d) Unless
the Agent shall have received notice from the Borrower prior to the date on
which any payment is due to the Banks hereunder that the Borrower will not make
such payment in full, the Agent may assume that the Borrower has made such
payment in full to the Agent on such date and the Agent may, in reliance upon
such assumption, cause to be distributed to each Bank on such due date an amount
equal to the amount then due such Bank.  If and to the extent that the
Borrower shall not have so made such payment in full to the Agent, each Bank
shall repay to the Agent forthwith on demand such amount distributed to such
Bank together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Agent, at the Federal Funds Rate.

     

    Section
2.11 Increased Costs and Capital
Requirements.  (a)  If,
due to either (i) the introduction of or any change (other than any change by
way of imposition or increase of reserve requirements included in the Eurodollar
Rate Reserve Percentage) in or in the interpretation of any law or regulation by
any governmental authority charged with the interpretation or administration
thereof or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Bank of agreeing to make or
making, funding or maintaining any Eurodollar Rate Advance (excluding, for
purposes of this Section 2.11, any such increased costs resulting from (x) Taxes
or Other Taxes (as to which Section 2.12 shall govern) and (y) changes in the
basis of taxation of overall net income or overall gross income by the United
States or by the foreign jurisdiction or state under the laws of which such Bank
is organized or has its Applicable Lending Office or any political subdivision
thereof), then the Borrower shall from time to time, within 15 days after demand
by such Bank (with a copy of such demand to the Agent), pay to the Agent for the
account of such Bank additional amounts sufficient to compensate such Bank for
such increased cost; provided, however, that the Borrower shall not be required
to pay to such Bank any portion of such additional amounts that are incurred
more than 90 days prior to any such demand, unless such additional amounts had
not been imposed or were not determinable on the date that is 90 days prior to
such demand.  A certificate setting forth in reasonable detail the
amount of such increased cost, submitted to the Borrower and the Agent by such
Bank, shall be conclusive and binding for all purposes, absent manifest
error.

     

    (b) If
following the introduction of or any change in any applicable law or regulation
or any guideline or request from any central bank or other governmental
authority (whether or not having the force of law) any Bank determines that
compliance by such Bank with any such law or regulation or guideline or request
regarding capital adequacy affects or would affect the amount of capital
required or expected to be maintained by such Bank or any Person controlling
such Bank and that the amount of such capital is increased by or based upon the
existence of such Bank's commitment to lend hereunder and other commitments of
such type (or similar contingent obligations), then, within 15 days after demand
by such Bank (with a copy of such demand to the Agent), the Borrower shall pay
to the Agent for the account of such Bank, from time to time as specified by
such Bank, additional amounts sufficient to compensate  such Bank
or  such  Person in  the light of  such
circumstances,  to the  extent that such Bank

     

    
       

      
        17

        
          

        

      

       

    

    reasonably
determines such increase in capital to be allocable to the existence of such
Bank's commitment to lend hereunder; provided, however, that the
Borrower shall not be required to pay to such Bank any portion of such
additional amounts that are incurred more than 90 days prior to any such demand,
unless such additional amounts had not been imposed or were not determinable on
the date that is 90 days prior to such demand.  A certificate setting
forth in reasonable detail such amounts submitted to the Borrower and the Agent
by such Bank shall be conclusive and binding for all purposes, absent manifest
error.

     

    (c) Each Bank
shall make reasonable efforts (consistent with its internal policies and legal
and regulatory restrictions) to select a jurisdiction for its Applicable Lending
Office or change the jurisdiction of its Applicable Lending Office, as the case
may be, so as to avoid the imposition of any increased costs under this Section
2.11 or to eliminate the amount of any such increased cost which may thereafter
accrue; provided that no such
selection or change of the jurisdiction for its Applicable Lending Office shall
be made if, in the reasonable judgment of such Bank, such selection or change
would be disadvantageous to such Bank.

     

    Section
2.12 Taxes.  (a)  Any
and all payments by the Borrower hereunder or under the Notes shall be made, in
accordance with Section 2.10, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges and
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Bank and the Agent, taxes imposed on its overall net income (including
branch profits), and franchise taxes imposed on or measured by net income, by
the jurisdiction under the laws of which such Bank or the Agent (as the case may
be) is organized or any political subdivision thereof and, in the case of each
Bank, taxes imposed on its overall net income (including branch profits), and
franchise taxes imposed on or measured by net income, by the jurisdiction of
such Bank's Applicable Lending Office or principal executive office or any
political subdivision thereof, and all liabilities with respect thereto (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"), except as
may otherwise be required by law.  If the Borrower shall be required
by law to deduct any Taxes from or in respect of any sum payable hereunder or
under any Note to any Bank or the Agent, (i) the sum payable shall be increased
by such amount (an "Additional Amount")
as may be necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 2.12) such
Bank or the Agent (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 pay the full amount deducted
to the relevant taxation authority or other authority in accordance with
applicable law.  Any such payment by the Borrower shall be made in the
name of the relevant Bank or the Agent (as the case may be).

     

    (b) In
addition, the Borrower agrees to pay any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies which
arise from any payment made hereunder or under the Notes or from the execution,
delivery or registration of, performing under, or otherwise with respect to,
this Agreement or any of the Notes (hereinafter referred to as "Other
Taxes").

     

    (c) The
Borrower will indemnify each Bank and the Agent for the full amount of Taxes and
Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by
any jurisdiction on amounts payable under this Section 2.12) imposed on or paid
by such Bank or the Agent (as the case may be) and any liability (including
penalties, interest and reasonable expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted.  Payments under any indemnification provided for in this
Section 2.12(c) shall be made within 30 days from the date such Bank or the
Agent (as the case may be) makes written demand therefor describing such Taxes
or Other Taxes in reasonable detail.

     

    
       

      
        18

        
          

        

      

       

    

    (d) If the
Agent or a Bank reasonably determines that it has finally and irrevocably
received a refund in respect of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower, or with respect to which the Borrower has paid
Additional Amounts, pursuant to this Section 2.12, it shall within 30 days from
the date of such receipt pay over such refund to the Borrower (but only to the
extent such refund is attributable, as reasonably determined by such Agent or
Bank, to such indemnity payments made, or Additional Amounts paid, by the
Borrower under this Section 2.12 with respect to the Taxes or Other Taxes giving
rise to such refund), net of all reasonable out-of-pocket expenses of the Agent
or Bank and without interest (other than interest paid by the relevant taxation
authority with respect to such refund); provided, however, that the
Borrower, upon the request of the Agent or Bank, agrees to repay the amount paid
over to the Borrower (plus penalties, interest or other charges, if any, imposed
by the relevant taxation authority in respect of such repayment) to the Agent or
Bank in the event the Agent or Bank is required to repay such refund to the
applicable taxation authority.  Nothing contained in this Section
2.12(d) shall interfere with the right of the Agent or any Bank to arrange its
tax affairs in whatever manner it determines appropriate nor oblige the Agent or
any Bank to claim any tax credit or to disclose any information relating to its
tax affairs or any computations in respect thereof or require the Agent or any
Bank to do anything that would prejudice its ability to benefit from any other
tax relief to which it may be entitled.

     

    (e) Within 30
days after the date of any payment of Taxes, the Borrower will furnish to the
Agent, at its address referred to in Section 8.02, the original or a certified
copy of a receipt evidencing payment thereof (or other evidence of payment
reasonably satisfactory to the Agent).  In the case of any payment
hereunder or under the Notes by or on behalf of the Borrower through an account
or branch outside the United States or by or on behalf of the Borrower by a
payor that is not a United States person, if the Borrower determines that no
Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause
such payor to furnish, to the Agent, at such address, an opinion of counsel
reasonably acceptable to the Agent stating that such payment is exempt from
Taxes imposed by the jurisdiction from which such payment is
made.  For purposes of this Section 2.12(e) and Section 2.12(f), the
terms "United
States" and "United States person"
shall have the meanings specified in Section 7701 of the Code.

     

    (f) Each Bank
organized under the laws of a jurisdiction outside the United States, (i) on or
prior to the date of the Initial Extension of Credit in the case of each such
Bank listed on the signature pages hereof, (ii) on the date of the Assignment
and Acceptance pursuant to which it becomes a Bank, (iii) on or before the date,
if any, it changes its Applicable Lending Office, and (iv) from time to time
thereafter if reasonably requested in writing by the Borrower or the Agent or
promptly upon the obsolescence or invalidity of any form previously delivered by
such Bank (but only so long as such Bank remains lawfully able to do so), shall
provide the Agent and the Borrower with two original Internal Revenue Service
Forms W-8BEN or W-8ECI (or, in the case of a Bank that is entitled to claim
exemption from withholding of United States federal income tax under Section
871(h) or 881(c) of the Code, (A) a certificate representing that such Bank is
not a "bank" for purposes of Section 881(c) of the Code, is not a 10-percent
shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the
Borrower and is not a controlled foreign corporation related to the Borrower
(within the meaning of Section 864(d)(4) of the Code) and (B) Internal Revenue
Service Form W-8BEN), as appropriate, or any successor or other form prescribed
by the Internal Revenue Service, properly completed and duly executed by such
Bank, certifying that such Bank is exempt from or entitled to a reduced rate of
United States withholding tax on payments pursuant to this Agreement or the
Notes (or, in the case of a Bank providing the certificate described in clause
(A), certifying that such Bank is a foreign corporation, partnership, estate or
trust).  If the forms provided by a Bank at the time such Bank first
becomes a party to this Agreement indicate or require a United States interest
withholding tax rate in excess of zero, withholding tax at such rate shall be
considered excluded from Taxes for purposes of this Section 2.12 unless and
until such Bank provides the appropriate forms certifying that a lesser rate
applies, whereupon withholding tax at such lesser rate only shall  be
considered excluded from Taxes for  periods governed by such forms;
provided, however, that
if,

     

    
       

      
        19

        
          

        

      

       

    

    at the
effective date of the Assignment and Acceptance pursuant to which a Bank becomes
a party to this Agreement (or the date, if any, a Bank changes its Applicable
Lending Office), the Bank assignor (or such Bank) was entitled to payments under
subsection (a) of this Section 2.12 in respect of United States withholding tax
with respect to interest paid at such date, then, to such extent, the term Taxes
shall include (in addition to withholding taxes that may be imposed in the
future or other amounts otherwise includable in Taxes, subject to the provisions
of this subsection (f)) United States withholding tax, if any, applicable with
respect to the Bank assignor (or such Bank) on such date.

     

    (g) For any
period with respect to which a Bank has failed to provide the Borrower with the
appropriate form described in subsection (f) above (other than if such failure
is due to a change in law, or in the interpretation or application thereof by
any governmental authority charged with the interpretation or application
thereof, occurring after the date on which a form originally was required to be
provided or if such form otherwise is not required under subsection (f) above),
such Bank shall not be entitled to indemnification or payment of an Additional
Amount under subsection (a) or (c) of this Section 2.12 with respect to Taxes
imposed by the United States to the extent such United States Taxes exceed the
United States Taxes that would have been imposed had such form been provided;
provided, however, that should
a Bank become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Bank shall reasonably
request to assist such Bank to recover such Taxes.

     

    (h) Any Bank
claiming any indemnity payment or Additional Amounts payable pursuant to this
Section 2.12 shall use commercially reasonable efforts (consistent with its
generally applicable internal policy and legal and regulatory restrictions) to
file any certificate or document reasonably requested in writing by the Borrower
or to designate a different Applicable Lending Office following the reasonable
request in writing of the Borrower if the making of such a filing or change
would avoid the need for or reduce the amount of any such indemnity payment or
Additional Amounts that may thereafter accrue and would not, in the sole
determination of such Bank, require the disclosure of information that the Bank
reasonably considers confidential, or be otherwise disadvantageous to such
Bank.

     

    Section
2.13 Sharing of Payments,
Etc.  If any Bank shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) on
account of the principal of or interest on the Advances owing to it (except
amounts payable pursuant to Section 2.07, 2.11, 2.12, 2.16 or 8.08 and except
that (a) any Bank may receive less than its ratable share of interest to the
extent Section 8.06 is applicable to it and (b) if, in respect of any Change in
Control, not all Banks are Exercising Banks, then payments due from the Borrower
pursuant to Section 2.18 shall be distributed ratably among all such
Exercising Banks (and not to those Banks that are not Exercising Banks)) in
excess of its ratable share of payments on account of the principal of or
interest on the Advances obtained by all the Banks, such Bank shall forthwith
purchase from the other Banks such participations in the Advances owing to them
as shall be necessary to cause such purchasing Bank to share the excess payment
ratably with each of them, provided, however, that if all or any portion of such
excess payment is thereafter recovered from such purchasing Bank, such purchase
from each Bank shall be rescinded and such Bank shall repay to the purchasing
Bank the purchase price to the extent of such Bank's ratable share (according to
the proportion of (i) the amount of the participation purchased from such Bank
as a result of such excess payment to (ii) the total amount of such excess
payment) of such recovery together with an amount equal to such Bank's ratable
share (according to the proportion of (x) the amount of such Bank's required
repayment to (y) the total amount so recovered from the purchasing Bank) of any
interest or other amount paid or payable by the purchasing Bank in respect of
the total amount so recovered.  The Borrower agrees that any Bank so
purchasing a participation from another Bank pursuant to this Section 2.13 may,
to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Bank were the direct creditor of the Borrower in the amount of such
participation.

    Section
2.14 Illegality.  Notwithstanding
any other provision of this Agreement, if any Bank ("Affected Bank") shall
notify the Borrower and the Agent that the introduction of or any change in any
law or regulation makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for any Bank, or its Eurodollar Lending
Office, to perform its obligations hereunder to make Eurodollar Rate Advances or
to fund or maintain Eurodollar Rate Advances hereunder, (i) the obligation of
the Affected Bank to make, or to Convert Advances into, Eurodollar Rate Advances
shall forthwith be suspended (and any request by the Borrower for a Borrowing
comprised of Eurodollar Rate Advances shall, as to each Affected Bank, be deemed
a request for a Base Rate Advance to be made on the same day as the Eurodollar
Rate Advances of the Banks that are not Affected Banks and such Base Rate
Advance shall be considered as part of such Borrowing) until the Affected Bank
shall notify the Borrower, the Banks and the Agent that the circumstances
causing such suspension no longer exist and (ii) forthwith after such notice
from an Affected Bank to the Agent and the Borrower, all Eurodollar Rate
Advances of such Affected Bank shall be deemed to be Converted to Base Rate
Advances (but will otherwise continue to be considered as a part of the
respective Borrowings that they were a part of prior to such Conversion);
provided, however, that, before making any such demand, such Bank agrees to use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different Eurodollar Lending Office if the making
of such a designation would allow such Bank or its Eurodollar Lending Office to
continue to perform its obligations to make Eurodollar Rate Advances or to
continue to fund or maintain Eurodollar Rate Advances and would not, in the
judgment of such Bank, be otherwise materially disadvantageous to such
Bank.  In the event any Bank shall notify the Agent of the occurrence
of any circumstance contemplated under this Section 2.14, all payments and
prepayments of principal that would otherwise have been applied to repay the
Eurodollar Rate Advances that would have been made by such Bank or the Converted
Eurodollar Rate Advances shall instead be applied to repay the Base Rate
Advances made by such Bank in lieu of such Eurodollar Rate Advances or resulting
from the Conversion of such Eurodollar Rate Advances and shall be made at the
time that payments on the Eurodollar Rate Advances of the Banks that are not
Affected Banks are made.  Each Bank that has delivered a notice of
illegality pursuant to this Section 2.14 above agrees that it will notify the
Borrower as soon as practicable if the conditions giving rise to the illegality
cease to exist.

     

    Section
2.15 Conversion of
Advances.  The Borrower may on any Business Day, upon notice
given to the Agent not later than 11:00 A.M. (New York City time) on the third
Business Day prior to the date of the proposed Conversion and subject to the
provisions of Sections 2.02(b), 2.08 and 2.14, Convert all Advances of one Type
comprising the same Borrowing into Advances of the other Type; provided,
however, that (i) any Conversion of any Eurodollar Rate Advances into Base Rate
Advances shall be made on, and only on, the last day of an Interest Period for
such Eurodollar Rate Advances, except as provided in Section 2.14, and (ii)
Advances comprising a Borrowing may not be Converted into Eurodollar Rate
Advances if the outstanding principal amount of such Borrowing is less than
$5,000,000 or if any Event of Default under Section 6.01(a) shall have occurred
and be continuing on the date the related notice of Conversion would otherwise
be given pursuant to this Section 2.15.  Each such notice of a
Conversion shall, within the restrictions specified above, specify (i) the date
of such Conversion, (ii) the Advances to be Converted, and (iii) if such
Conversion is into Eurodollar Rate Advances, the duration of the initial
Interest Period for each such Advance.  Each notice of Conversion
shall be irrevocable and binding on the Borrower.  If any Event of
Default under Section 6.01(a) shall have occurred and be continuing on the third
Business Day prior to the last day of any Interest Period for any Eurodollar
Rate Advances, the Borrower agrees to Convert all such Advances into Base Rate
Advances on the last day of such Interest Period.

     

    Section
2.16 Replacement or Removal of
Bank.  In the event that any Bank shall claim payment of any
increased costs pursuant to Section 2.11 or the Borrower is required to pay any
Additional Amounts, Taxes or Other Taxes to or on account of any Bank pursuant
to Section 2.12, or any Bank exercises its  rights under Section 2.14,
or  if any Bank fails to  execute and deliver a consent,

    or waiver
to this Agreement requested by the Borrower by the date specified by the
Borrower (or gives the Borrower written notice prior to such date of its
intention not to do so), the Borrower shall have the right, if no Default or
Event of Default then exists, to (a) replace such Bank with an Eligible Assignee
in accordance with Section 8.08(a), (b) and (d) (including execution of an
appropriate Assignment and Acceptance); provided that such
Eligible Assignee (i) shall unconditionally offer in writing (with a copy to the
Agent) to purchase on a date therein specified all of such Bank's rights
hereunder and interest in the Advances owing to such Bank and the Note held by
such Bank without recourse at the principal amount of such Note plus interest
and Facility Fees accrued but unpaid thereon to the date of such purchase and
(ii) shall execute and deliver to the Agent an Assignment and Acceptance, as
assignee, pursuant to which such Eligible Assignee becomes a party hereto with a
Commitment equal to that of the Bank being replaced (plus, if such Eligible
Assignee is already a Bank, the amount of its Commitment prior to such
replacement), provided, further,
that no Bank or other Person shall have any obligation to increase its
Commitment or otherwise to replace, in whole or in part, any Bank or (b) remove
such Bank without replacing it by (x) giving notice to such Bank and the Agent
of such removal and (y) simultaneously with such notice paying to the Agent for
the account of such Bank all principal owed to such Bank, all accrued interest
and Facility Fees owed to such Bank, all requested costs accruing to the date of
removal which the Borrower is obligated to pay to such Bank under Section 8.04
and all other amounts owed by the Borrower to such Bank under this Agreement;
provided that
the Borrower may not remove a Bank pursuant to this clause (b) if the aggregate
Commitments of all Banks so removed would exceed $150,000,000 or, if immediately
after giving effect to such removal and payment, the aggregate Unused
Commitments of the Banks not so removed would be less than zero.  Upon
satisfaction of the requirements for replacement set forth in the first sentence
of this Section 2.16, payment to such Bank of the purchase price in immediately
available funds by the Eligible Assignee replacing such Bank, execution of such
Assignment and Acceptance by such Bank (which Bank shall execute such Assignment
and Acceptance contemporaneously with or prior to the payment of all amounts
required to be paid to it pursuant to this sentence), such Eligible Assignee and
the Agent, the payment by the Borrower of all requested costs accruing to the
date of purchase which the Borrower is obligated to pay under Section 8.04 and
all other amounts owed by the Borrower to such Bank under this Agreement (other
than Facility Fees accrued for the account of such Bank and the principal of and
interest on the Advances of such Bank purchased by such Eligible Assignee) and
notice by the Borrower to the Agent that such payment has been made, such
Eligible Assignee shall constitute a "Bank" hereunder with a Commitment as so
specified and the Bank being so replaced shall no longer constitute a "Bank"
hereunder except that the rights under Sections 2.07, 2.11, 2.12 and 8.04 of the
Bank being so replaced shall continue with respect to events and occurrences
occurring before or concurrently with its ceasing to be a "Bank"
hereunder.  If, however, such Eligible Assignee fails to purchase such
rights and interest on such specified date in accordance with the terms of such
offer or such Eligible Assignee or the Agent fails to execute the relevant
Assignment and Acceptance, the Borrower shall continue to be obligated to pay
the increased costs to such Bank pursuant to Section 2.11 or the additional
amounts pursuant to Section 2.12, as the case may be.  Upon
satisfaction of the requirements for removal set forth in the first sentence of
this Section 2.16, the Bank being so removed shall no longer constitute a "Bank"
hereunder except that the rights under Sections 2.07, 2.11, 2.12 and 8.04 of the
Bank being so removed shall continue with respect to events and occurrences
occurring before or concurrently with its ceasing to be a "Bank"
hereunder.  

     

    Section
2.17 Evidence of
Indebtedness.  Each Bank shall maintain in accordance with its
usual practice an account or accounts evidencing the indebtedness of the
Borrower to such Bank resulting from each Advance owing to such Bank from time
to time, including the amounts of principal and interest payable and paid to
such Bank from time to time hereunder.  The Borrower agrees that upon
notice by any Bank to the Borrower (with a copy of such notice to the Agent) to
the effect that a promissory note or other evidence of indebtedness is required
or appropriate in order for such Bank to evidence (whether for purposes of
pledge, enforcement or otherwise) the Advances owing to, or to be made by, such
Bank, the
Borrower  shall  promptly  execute  and  deliver  to  such  Bank,  with  a  copy  to  the  Agent,  a  Note  in

     

    
       

      
        22

        
          

        

      

       

    

    substantially
the form of Exhibit A  hereto, payable to the order of such Bank in a
principal amount equal to the Commitment of such Bank.  All references
to Notes in the Loan Documents shall mean Notes, if any, to the extent issued
hereunder.

     

    Section
2.18 Change in
Control.  (a) If a Change in Control occurs, (i) the Borrower
shall promptly notify the Agent (which shall promptly notify the Banks) of such
occurrence and specify in such notice a date (the "Early Maturity Date")
on which the matters referred to in clause (ii) of this Section 2.18(a) shall
occur as to each Bank, at the option of such Bank, which date shall be any
Business Day not earlier than 60 days after, and not later than 90 days after,
the Borrower gives such notice, (ii) any Bank may, at its sole option, elect to
require the following to occur on the Early Maturity Date: (x) termination of
its Commitment, if any and (y) payment in full by the Borrower of all
Obligations owed to such Bank; provided that any such election
shall elect all (and not less than all) of the actions referred to in such
clauses (x) and (y).  

     

    (b)   Any
Bank (an "Exercising
Bank") may exercise its rights pursuant to Section 2.18(a) by giving the
Agent and the Borrower a written notice of such exercise not earlier than 20
days after, and not later than 40 days after, such Bank's receipt of a notice
from the Agent under Section 2.18(a) (but the failure to so exercise such rights
in respect of any Change in Control shall not impair the exercise of any such
rights in respect of any other Change in Control).

     

    (c)    On
the relevant Early Maturity Date, each Exercising Bank's Commitment shall
terminate, and the Borrower shall pay in full all Obligations owed to such Bank
hereunder, including all of such Bank's outstanding Advances together with
interest thereon accrued to such Early Maturity Date and any amounts payable
pursuant to subsection 8.04(b), all Facility Fees accrued to such Early Maturity
Date with respect to such Bank's Commitment and all amounts then owing to such
Bank pursuant to Sections 2.07, 2.11, 2.12 and 8.04.  Upon termination
of such Bank's Commitment in accordance with this Section 2.18(c), such Bank
shall cease to be a party hereto, except that (i) rights of such Bank under
Sections 2.07, 2.11, 2.12 and 8.04 shall continue with respect to events and
occurrences occurring before or on such Early Maturity Date, (ii) the
obligations of such Bank under Section 7.05 shall continue as to events, actions
and circumstances arising on or prior to such Early Maturity Date. Nothing
contained in this Section 2.18 shall impair the obligation of the Borrower to
pay any amount owing to the Banks hereunder when due prior to an Early Maturity
Date.

     

    (d)    The
Borrower shall have the right, on or before the Early Maturity Date, to replace
each Exercising Bank with, and add as "Banks" under this Agreement in place
thereof, one or more Eligible Assignees (each, an "Additional Change in Control
Commitment Bank") as provided in Section 8.08, each of which Additional
Change in Control Commitment Banks shall have entered into an Assignment and
Acceptance pursuant to which such Additional Change in Control Commitment Bank
shall, effective as of such Early Maturity Date, undertake a Commitment (and, if
any such Additional Change in Control Commitment Bank is already a Bank, its
Commitment shall be in addition to any other Commitment of such Bank hereunder
on such date).

its business as now being conducted and to execute, deliver and perform each
Loan Document to which it is or is to be a party, except for any failures to be

Material Adverse Effect.

     

    
       

      
        25

that are subject to any arrangement with the Agent or any Bank (herein or
otherwise) whereby the Borrower's right or ability to sell, pledge or otherwise
dispose of assets is in any way restricted (or pursuant to which the exercise of

portion of the Advances or any other amount payable hereunder or under any such
other arrangement), will be margin stock (within the meaning of Regulation U);

certificate or statement furnished to the Agent or the Banks by or on behalf of

Agreement or the Notes (as modified or supplemented by other information
furnished) contains as of the date such statement, information, document or
certificate was so furnished any untrue statement of a material fact or omitted

respect to any such information, exhibit or report consisting of statements,
estimates, pro forma financial information, forward-looking statements and
projections regarding the future performance of the Borrower or any of its

representation or warranty is made other than that such Projections have been
prepared in good faith based upon assumptions believed to be reasonable at the
time.

organization in each jurisdiction in which qualification is necessary or
desirable in view of its business and operations or the ownership of its

the Borrower nor any Subsidiary shall be required to pay and discharge any such
tax, assessment, charge, levy or claim if (x) the failure to do so (in the

    (h) Transactions
with Affiliates.  Conduct, and cause each of its Subsidiaries to
conduct, all transactions otherwise permitted under this Agreement with any of
their Affiliates on terms that are fair and reasonable and, if a comparable

transaction with a Person not an Affiliate; provided, however, that the
foregoing restriction shall not apply to

extent permitted by law, customary loans, advances, fees and compensation paid
to, and indemnity provided on behalf of, officers, directors, employees or

    Section
7.01 Authorization and
Action.  Each Bank hereby appoints and authorizes the Agent to
take such action as Agent on its behalf and to exercise such powers under the
Loan Documents as are delegated to the Agent by the terms hereof or of any other
Loan Document, together with such powers and discretion as are reasonably
incidental thereto.  As to any matters not expressly provided for by
this Agreement (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Required Banks and such instructions shall be binding upon all Banks and all
holders of Notes; provided, however, that the Agent shall not be required to
take any action which exposes the Agent to personal liability or which is
contrary to any Loan Document or applicable law.  The Agent agrees to
give to each Bank prompt notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement.

     

    Section
7.02 Agent's Reliance,

action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants or experts; (ii) makes no warranty or
representation to any Bank and shall not be responsible to any Bank for any
statements, warranties or representations (whether written or oral) made in or
in connection with any of the Loan Documents or any other instrument or
document; (iii) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of any of
Loan Documents or any other instrument or document on the part of the Borrower
or any Subsidiary of the Borrower or to inspect the Property (including the
books and records) of the Borrower or any Subsidiary of the Borrower; (iv) shall
not be responsible to any Bank for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of any of the Loan Documents
or any other instrument or document; and (v) shall incur no liability under or
in respect of any of Loan Documents or any other instrument or document by
acting upon any notice (including telephonic notice), consent, certificate or

believed by it to be genuine and signed, given or sent by the proper party or
parties.

     

    Section
7.03 The Agent and its
Affiliates.  With respect to its Commitment, the Advances owed
to it and the Notes issued to it, each Bank which is also the Agent shall have
the same rights and powers under this Agreement as any other Bank and may
exercise the same as though it were not the Agent; and the term "Bank" or
"Banks" shall, unless otherwise expressly indicated, include any Bank serving as
the Agent in its individual capacity.  Any Bank serving as the Agent

any Person who may do business with or own securities of the Borrower or any
Affiliate of the Borrower, all as if such Bank were not the Agent and without

or any of its affiliates shall be or become an indenture trustee under the Trust
Indenture Act of 1939 (as amended, the "Trust Indenture Act")
in respect of any securities issued or guaranteed by the Borrower, the parties
hereto acknowledge and agree that any payment or property received in

Trust Indenture Act.  

     

    Section
7.04 Bank Credit
Decision.  Each Bank acknowledges that it has, independently

Statements and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this

and without reliance upon the Agent or any other Bank and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the Loan
Documents or any other instrument or document.

     

    Section
7.05 Indemnification.  The
Banks agree to indemnify the Agent (to the extent not promptly reimbursed by the
Borrower), ratably according to the respective principal amounts of the Advances
then held by each of such Banks (or if no Advances are at the time outstanding
or if any Advances are held by Persons which are not such Banks, ratably
according to either (a) the respective amounts of the Banks' Commitments, or (b)
if no Commitments are at the time outstanding, the respective amounts of the
Commitments immediately prior to the time the Commitments ceased to be
outstanding), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses and disbursements
of any kind or nature whatsoever which may be imposed on, incurred by, or
asserted against the Agent in any way relating to or arising out of any of the
Loan Documents or any other instrument or document furnished pursuant hereto or
in connection herewith, or any action taken or omitted by the Agent under any of
the Loan Documents or any other instrument or document furnished pursuant hereto
or in connection herewith ("Indemnified Costs"); provided that no Bank shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Agent's gross negligence or willful misconduct as found in a final,
non-appealable judgment by a court of competent jurisdiction.  Without
limitation of the foregoing, each Bank agrees to reimburse the Agent promptly
upon demand for such Bank's ratable share of any costs and expenses (including,
without limitation, counsel fees) incurred by the Agent in connection with the

or legal advice in respect of rights or responsibilities under, any of the Loan
Documents or any other instrument or document furnished pursuant hereto or in
connection herewith to the extent that the Agent is not reimbursed for such
expenses by the Borrower.  In the case of any investigation,
litigation or proceeding giving rise to any Indemnified Costs, this

proceeding is brought by the Agent, any other Agent, any Bank or a third
party.

notice thereof to the Banks and the Borrower and may be removed at any time with
or without cause by the Required Banks.  Upon any such resignation or
removal, the Required Banks shall have the right to appoint a successor Agent
which, if such successor Agent is not a Bank, is approved by the Borrower (which
approval will not be unreasonably withheld).  If no successor Agent
shall have been so appointed by the Required Banks (and, if not a Bank, approved
by the Borrower), and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation or the Required Banks'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Banks, appoint a successor Agent, which shall be a commercial bank organized or
licensed under the laws of the United States of America or of any State thereof

or any Note, nor consent to any departure by the Borrower therefrom, shall in
any event be effective unless the same shall be in writing and signed by the
Required Banks, and then such waiver or consent shall be effective only in the

Agent.

     

    (b) The
Borrower hereby agrees that it will provide to the Agent all information,
documents and other materials that it is obligated to furnish to the Agent
pursuant to the Loan Documents, including, without limitation, all notices,
requests, financial statements, financial and other reports, certificates and
other information materials, but excluding any such communication that (i)
relates to a request for a new, or a Conversion of an existing, Borrowing or
other extension of credit (including any election of an interest rate or
interest period relating thereto), (ii) relates to the payment of any principal
or other amount due under this Agreement prior to the scheduled date therefor,
(iii) provides notice of any Default or Event of Default, (iv) is required to be
delivered to satisfy any condition precedent to the effectiveness of this
Agreement and/or any Borrowing or other extension of credit hereunder or (v) is
delivered by posting to a website as provided in Section 5.01(d) (all such
non-excluded communications being referred to herein collectively as "Communications"), by
transmitting the Communications in an electronic/soft medium in a format
acceptable to the Agent to oploanswebadmin@citigroup.com.  In
addition, the Borrower agrees to continue to provide the Communications to the
Agent in the manner specified in the Loan Documents but only to the extent
requested by the Agent.  The Borrower further agrees that the Agent
may make the Communications available to the Banks by posting the Communications
on Intralinks or a substantially similar electronic transmission system (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 communications, or the
adequacy of the Platform and expressly disclaim liability for errors or
omissions in the communications.  No warranty of any kind, express,
implied or statutory, including, without limitation, 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 the Agent
Parties in connection with the Communications or the Platform.  In no
event shall the Agent or any of its affiliates or any of their respective
officers, directors, employees, agents, advisors or representatives
(collectively, "Agent
Parties") have any
liability to the Borrower, any Bank or any other Person or entity for damages of
any kind, including, without limitation, direct or indirect, special, incidental
or consequential damages, losses or expenses (whether in tort, contract or
otherwise) arising out of the Borrower's or the Agent's transmission of
Communications through the internet, except to the extent the liability of any
Agent Party is found in a final non-appealable judgment by a court of competent
jurisdiction to have resulted primarily from such Agent Party's gross negligence
or willful misconduct.  The Agent agrees that the receipt of
the Communications by the Agent at its e-mail address set forth above shall
constitute effective delivery of the Communications to the Agent for purposes of
the Loan Documents.

     

    
       

      
        38

        
          

        

      

       

    

    (c) Each Bank
agrees that notice to it (as provided in the next sentence) (a "Notice") specifying
that any Communications have been posted to the Platform shall constitute
effective delivery of such information, documents or other materials to such
Bank for purposes of this Agreement; provided that if
requested by any Bank the Agent shall deliver a copy of the Communications to
such Bank by email or facsimile.  Each Bank agrees (i) to notify the
Agent in writing of such Bank's e-mail address to which a Notice may be sent by
electronic transmission (including by electronic communication) on or before the
date such Bank becomes a party to this Agreement (and from time to time
thereafter to ensure that the Agent has on record an effective e-mail address
for such Bank) and (ii) that any Notice may be sent to such e-mail
address.

     

    (d) Nothing
herein shall prejudice the right of the Agent or any Bank to give any notice or
other communication pursuant to any Loan Document in any other manner specified
in such Loan Document.

     

    Section
8.03 No Waiver;
Remedies.  No failure on the part of any Bank or the Agent to
exercise, and no delay in exercising, any right hereunder or under any Note
shall operate as a waiver thereof; nor shall any single or partial exercise of
any such right preclude any other or further exercise thereof or the exercise of
any other right.  The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

     

    Section
8.04 Expenses and Taxes;
Compensation.  (a)  The
Borrower agrees to pay on demand (i) all reasonable out-of-pocket costs and
expenses (including, without limitation, reasonable fees and expenses of
counsel) of the Co-Lead Arrangers and the Agent and each of their respective
affiliates in connection with the preparation, execution, delivery and
administration of the Loan Documents and the other documents and instruments
delivered hereunder or in connection with any amendments, modifications,
consents or waivers in connection with the Loan Documents, (ii) all reasonable
fees and expenses of counsel for the Co-Lead Arrangers and the Agent and, during
the existence of any Event of Default, any Bank with respect to advising either
Co-Lead Arranger or the Agent or, during the existence of any Event of Default,
any Bank as to its rights and responsibilities under the Loan Documents and
(iii) all reasonable out-of-pocket costs and expenses (including, without
limitation, reasonable fees and expenses of counsel) of the Co-Lead Arrangers,
the Agent and each Bank in connection with the enforcement (whether through
negotiations, legal proceedings or otherwise) of the Loan Documents (including
the enforcement of rights under this Section 8.04(a)) and the other documents
and instruments delivered hereunder and rights and remedies hereunder and
thereunder.

     

    (b) If any
payment or purchase of principal of, or Conversion of, any Eurodollar Rate
Advance is made other than on the last day of the Interest Period for such
Advance, as a result of a payment, purchase or Conversion pursuant to Section
2.08, Section 2.09, Section 2.14, Section 2.15 or Section 2.16, acceleration of
the maturity of the Advances pursuant to Section 6.01 or for any other reason,
the Borrower shall, within 15 days after demand by any Bank (with a copy of such
demand to the Agent), pay to the Agent for the account of such Bank any amounts
required to compensate such Bank for any additional losses, costs or expenses
which it may reasonably incur as a result of such payment, purchase or
Conversion, including, without limitation, any loss (excluding loss of
anticipated profits), cost or expense reasonably incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by any Bank to
fund or maintain such Advance.  A certificate as to the amount of such
additional losses, costs or expenses, submitted to the Borrower and the Agent by
such Bank, shall be conclusive and binding for all purposes, absent manifest
error.

     

    
       

      
        39

        
          

        

      

       

    

    (c) The
Borrower agrees to indemnify and hold harmless the Agent, the Banks, the Co-Lead
Arrangers and their respective directors, officers, employees, affiliates,
advisors, attorneys and agents (each, an "Indemnified Party")
from and against any and all claims, damages, losses, liabilities and expenses
(including, without limitation, fees and expenses of counsel) for which any of
them may become liable or which may be incurred by or asserted against any of
the Indemnified Parties in connection with or arising out of (i) any Loan
Document or any other document or instrument delivered in connection herewith or
the actual or proposed use of the proceeds of any Advance or any of the
transactions contemplated hereby or thereby, (ii) the existence of any condition
on any property of the Borrower or any of its Subsidiaries that constitutes a
violation of any environmental protection law or any other law, rule, regulation
or order, or (iii) any investigation, litigation, or proceeding, whether or not
any of the Indemnified Parties is a party thereto, related to or in connection
with any of the foregoing or any Loan Document, including, without limitation,
any transaction in which any proceeds of any Advance are applied, including,
without limitation, in each of the foregoing cases, any such claim, damage,
loss, liability or expense resulting from the negligence of any Indemnified
Party, but excluding any such claim, damage, loss, liability or expense sought
to be recovered by any Indemnified Party to the extent such claim, damage, loss,
liability or expense is found in a final, non-appealable judgment by a court of
competent jurisdiction to have resulted from the gross negligence or willful
misconduct of such Indemnified Party.

     

    (d) Except as
set forth in the next succeeding sentence, each of the Banks and the Agent and
each of their respective directors, officers, employees, affiliates, advisors
and agents shall not be liable to the Borrower for, and the Borrower agrees not
to assert any claim for, amounts constituting special, indirect, consequential,
punitive, treble or exemplary damages arising out of or in connection with any
breach by such Bank or the Agent of any of its obligations
hereunder.  If the Borrower becomes liable to a third party for
amounts constituting punitive, treble or exemplary damages as a result of a
breach of an obligation hereunder by a Bank or the Agent, as the case may be,
the Borrower shall be entitled to claim and recover (and does not waive its
rights to claim and recover) such amounts from such Bank or the Agent, as the
case may be, to the extent such Bank or the Agent, as the case may be, would be
liable to the Borrower for such amounts but for the limitation set forth in the
preceding sentence.

     

    (e) Without
prejudice to the survival of any other agreement of the Borrower hereunder, all
obligations of the Borrower under Section 2.11, Section 2.12 and this Section
8.04 shall survive the termination of the Commitments and this Agreement and the
payment in full of all amounts hereunder and under the Notes.

     

    Section
8.05 Right of
Set-Off.  Upon (i) the occurrence and during the continuance of
any Event of Default and (ii) the making by the Required Banks of the request or
the granting by the Required Banks of the consent specified by Section 6.01 to
authorize the Agent to declare the Advances due and payable pursuant to the
provisions of Section 6.01, each Bank is hereby authorized at any time and from
time to time, to the fullest extent permitted by law, to set off and apply any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Bank (or by any
branch, agency, subsidiary or other Affiliate of such Bank, wherever located) 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 Note held by such Bank, whether or not such Bank shall have made any demand
under this Agreement or any such Note and although such obligations may be
unmatured.  Each Bank agrees promptly to notify the Borrower after any
such set-off and application made by such Bank, provided that the failure to
give such notice shall not affect the validity of such set-off and
application.  The rights of each Bank under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of setoff) which such Bank may have.

     

    
       

      
        40

        
          

        

      

       

    

    Section
8.06 Limitation and Adjustment of
Interest.  (a)  Notwithstanding
anything to the contrary set forth herein, in any other Loan Document or in any
other document or instrument, no provision of any of the Loan Documents or any
other instrument or document furnished pursuant hereto or in connection herewith
is intended or shall be construed to require the payment or permit the
collection of interest in excess of the maximum non-usurious rate permitted by
applicable law.  Accordingly, if the transactions with any Bank
contemplated hereby would be usurious under applicable law, if any, then, in
that event, notwithstanding anything to the contrary in any Note payable to such
Bank, this Agreement or any other document or instrument, it is agreed as
follows: (i) the aggregate of all consideration which constitutes interest under
applicable law that is contracted for, taken, reserved, charged or received by
such Bank under any Note payable to such Bank, this Agreement or any other
document or instrument shall under no circumstances exceed the maximum amount
allowed by such applicable law, and any excess shall be canceled automatically
and, if theretofore paid, shall, at the option of such Bank, be credited by such
Bank on the principal amount of the indebtedness owed to such Bank by the
Borrower or refunded by such Bank to the Borrower, and (ii) in the event that
the maturity of any Note payable to such Bank is accelerated or in the event of
any required or permitted prepayment, then such consideration that constitutes
interest under law applicable to such Bank may never include more than the
maximum amount allowed by such applicable law and excess interest, if any, to
such Bank provided for in this Agreement or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if
theretofore paid, shall, at the option of such Bank, be credited by such Bank on
the principal amount of the indebtedness owed to such Bank by the Borrower or
refunded by such Bank to the Borrower.  In determining whether or not
the interest contracted for, taken, reserved, charged or received by any Bank
exceeds the maximum non-usurious rate permitted by applicable law, such
determination shall be made, to the extent that doing so does not result in a
violation of applicable law, by amortizing, prorating, allocating and spreading,
in equal parts during the period of the full stated term of the loans hereunder,
all interest at any time contracted for, taken, charged, received or reserved by
such Bank in connection with such loans.

     

    (b) In the
event that at any time the interest rate applicable to any Advance made by any
Bank would exceed the maximum non-usurious rate allowed by applicable law, the
rate of interest to accrue on the Advances by such Bank shall be limited to the
maximum non-usurious rate allowed by applicable law, but shall accrue, to the
extent permitted by law, on the principal amount of the Advances made by such
Bank from time to time outstanding, if any, at the maximum non-usurious rate
allowed by applicable law until the total amount of interest accrued on the
Advances made by such Bank equals the amount of interest which would have
accrued if the interest rates applicable to the Advances pursuant to Article II
had at all times been in effect.  In the event that upon the final
payment of the Advances made by any Bank and termination of the Commitment of
such Bank, the total amount of interest paid to such Bank hereunder and under
the Notes is less than the total amount of interest which would have accrued if
the interest rates applicable to such Advances pursuant to Article II had at all
times been in effect, then the Borrower agrees to pay to such Bank, to the
extent permitted by law, an amount equal to the excess of (a) the lesser of (i)
the amount of interest which would have accrued on such Advances if the maximum
non-usurious rate allowed by applicable law had at all times been in effect or
(ii) the amount of interest which would have accrued on such Advances if the
interest rates applicable to such Advances pursuant to Article II had at all
times been in effect over (b) the amount of interest otherwise accrued on such
Advances in accordance with this Agreement.

     

    Section
8.07 Binding
Effect.  This Agreement shall become effective as provided in
Section 3.01 hereof and thereafter shall be binding upon and inure to the
benefit of the Borrower and the Agent and each Bank and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights or obligations hereunder or under any other Loan Document or
any interest herein or therein without the prior written consent of all of the
Banks.

    Section
8.08 Assignments and
Participations.  (a)  Each
Bank may assign to one or more banks or other entities all or a portion of its
rights and obligations under this Agreement (including, without limitation, all
or a portion of its Commitment, the Advances owing to it and the Notes held by
it); provided, however, that (i) each such assignment shall be of a constant,
and not a varying, percentage of all rights and obligations under this
Agreement, (ii) except in the case of an assignment of all of a Bank's
rights and obligations under this Agreement, the amount of the Commitment of the
assigning Bank being assigned pursuant to each such assignment (determined as of
the date of the Assignment and Acceptance with respect to such assignment) shall
in no event be less than $5,000,000, (iii) each such assignment shall be to an
Eligible Assignee, and (iv) the parties to each such assignment shall execute
and deliver to the Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with the Notes subject to such assignment
and a processing and recordation fee of $3,000.  Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, (x) the assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, have the rights and
obligations of a Bank hereunder and (y) the Bank assignor thereunder shall, to
the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all of an assigning Bank's rights and
obligations under this Agreement, such Bank shall cease to be a party
hereto).

     

    (b) By
executing and delivering an Assignment and Acceptance, the Bank assignor
thereunder and the assignee thereunder confirm to and agree with each other and
the other parties hereto as follows: (i) other than as provided in such
Assignment and Acceptance, such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with any Loan Document or
any other instrument or document furnished pursuant hereto or in connection
herewith or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Loan Document or any other instrument or document
furnished pursuant hereto or in connection herewith; (ii) such assigning Bank
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of the Borrower or any other Person or the
performance or observance by the Borrower or any other Person of any of its
respective obligations under any Loan Document or any other instrument or
document furnished pursuant hereto or in connection herewith; (iii) such
assignee confirms that it has received a copy of this Agreement, together with
copies of the Financial Statements and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon the Agent, such assigning Bank or any other Bank and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement, any of the other Loan Documents or any other instrument or
document; (v) such assignee confirms that it is an Eligible Assignee; (vi) such
assignee appoints and authorizes the Agent to take such action as Agent on its
behalf and to exercise such powers and discretion under the Loan Documents as
are delegated to the Agent by the terms hereof or thereof, together with such
powers and discretion as are reasonably incidental thereto; and (vii) such
assignee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Bank.

     

    (c) The Agent
shall maintain at its address referred to in Section 8.02 a copy of each
Assignment and Acceptance delivered to and accepted by it and a register for the
recordation of the names and addresses of the Banks and the Commitment of, and
the principal amount of the Advances owing to, each Bank from time to time (the
"Register").  The
entries in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, the Agent and the Banks may treat
each  Person  whose name is recorded in the Register as
a Bank hereunder for all purposes of this

     

    
       

      
        42

        
          

        

      

       

    

    Agreement.  The
Register shall be available for inspection by the Borrower or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

     

    (d) Upon its
receipt of an Assignment and Acceptance executed by an assigning Bank and an
assignee representing that it is an Eligible Assignee, together with the Notes,
if any, subject to such assignment, the Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of Exhibit D, (i)
accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register and (iii) give prompt notice thereof to the
Borrower.  Within five Business Days after its receipt of such notice,
the Borrower shall execute and deliver to the Agent in exchange for the
surrendered Notes, if any, a new Note (if requested by the assignee) payable to
the order of such Eligible Assignee in an amount equal to the Commitment assumed
by it pursuant to such Assignment and Acceptance (plus any Commitment already
held by it) and, if the assigning Bank has retained a Commitment hereunder, a
new Note payable to the order of the assigning Bank in an amount equal to the
Commitment retained by it hereunder (such new Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Notes, shall be dated the effective date of such Assignment and Acceptance and
shall otherwise be in substantially the form of Exhibit A).

     

    (e) Each Bank
may sell participations to one or more banks or other entities (other than the
Borrower or any of its Affiliates) in or to all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the Advances owing to it and the Notes held by it);
provided, however, that (i)
such Bank's obligations under this Agreement (including, without limitation, its
Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Bank
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) such Bank shall remain the holder of any such Notes
for all purposes of this Agreement, (iv) the Borrower, the Agent and the other
Banks shall continue to deal solely and directly with such Bank in connection
with such Bank's rights and obligations under this Agreement, and (v) the terms
of any such participation shall not restrict such Bank's ability to make any
amendment or waiver of this Agreement or any Note or such Bank's ability to
consent to any departure by the Borrower therefrom without the approval of the
participant, except that the approval of the participant may be required to the
extent that such amendment, waiver or consent would reduce the principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, or postpone any date fixed for
any payment of principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation.

     

    (f) Any Bank
may, in connection with any assignment or participation or proposed assignment
or participation pursuant to this Section 8.08, disclose to the assignee or
participant or proposed assignee or participant, any information relating to the
Borrower or any of its Subsidiaries furnished to such Bank by or on behalf of
the Borrower or any of its Subsidiaries; provided that, prior
to any such disclosure, the assignee or participant or proposed assignee or
participant shall agree to comply with Section 8.14.

     

    (g) Notwithstanding
any other provision set forth in this Agreement, any Bank may at any time create
a security interest in all or any portion of its rights under this Agreement
(including, without limitation, the Advances owing to it and the Note or Notes
held by it) in favor of any Federal Reserve Bank in accordance with Regulation A
of the Federal Reserve Board.

     

    Section
8.09 Execution in
Counterparts.  This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.  Delivery of a
copy of a signature page to this Agreement by facsimile shall be as effective as
delivery of a manually executed counterpart of this Agreement.

    Section
8.10 Judgment.  (a)  If for
the purposes of obtaining judgment in any court it is necessary to convert a sum
due hereunder in Dollars into another currency, the parties hereto agree, to the
fullest extent that they may effectively do so, that the rate of exchange used
shall be that at which in accordance with normal banking procedures the Agent
could purchase Dollars with such other currency at Citibank's principal office
in London at 11:00 A.M. (London time) on the Business Day preceding that on
which final judgment is given.

     

    (b) If for
the purposes of obtaining judgment in any court it is necessary to convert a sum
due hereunder in a Foreign Currency into Dollars, the parties agree to the
fullest extent that they may effectively do so, that the rate of exchange used
shall be that at which in accordance with normal banking procedures the Agent
could purchase such Foreign Currency with Dollars at Citibank's principal office
in London at 11:00 A.M. (London time) on the Business Day preceding that on
which final judgment is given.

     

    (c) The
obligation of the Borrower in respect of any sum due from it in any currency
(the "Primary
Currency") to any Bank or the Agent hereunder shall, notwithstanding any
judgment in any other currency, be discharged only to the extent that on the
Business Day following receipt by such Bank or the Agent (as the case may be),
of any sum adjudged to be so due in such other currency, such Bank or the Agent
(as the case may be) may in accordance with normal banking procedures purchase
the applicable Primary Currency with such other currency; if the amount of the
applicable Primary Currency so purchased is less than such sum due to such Bank
or the Agent (as the case may be) in the applicable Primary Currency, the
Borrower agrees, as a separate obligation and notwithstanding any such judgment,
to indemnify such Bank or the Agent (as the case may be) against such loss, and
if the amount of the applicable Primary Currency so purchased exceeds such sum
due to any Bank or the Agent (as the case may be) in the applicable Primary
Currency, such Bank or the Agent (as the case may be) agrees to remit to the
Borrower such excess.

     

    Section
8.11 Governing
Law.  THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (EXCEPT AS
OTHERWISE EXPRESSLY SET FORTH IN ANY SUCH LOAN DOCUMENT), AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY, AND
SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE
STATE OF NEW YORK (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF
THE STATE OF NEW YORK), WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THAT
WOULD REQUIRE APPLICATION OF ANOTHER LAW.

     

    Section

    "Applicable Facility Fee
Rate" means, for any date, the rate per annum set forth in the table
below under the heading "Applicable Facility Fee Rate" opposite the debt rating
from S&P and Moody's, respectively, in effect on such date for the senior
unsecured long-term debt of the Borrower, with the higher of the two ratings to
be determinative in the case where the ratings from S&P and Moody's would
result in different Applicable Facility Fee Rates; provided, that if the
debt rating from one of the Rating Agencies is more than one level below the
debt rating from the other Rating Agency, then the debt rating one level below
the higher of the two shall be used in determining the Applicable Facility Fee
Rate; provided
further that
(a) if only one Rating Agency has a rating in effect on such date for the senior
unsecured long-term debt of the Borrower, then only such rating shall be used in
determining the Applicable Facility Fee Rate and (b) if neither Rating Agency
has a rating in effect on such date for the senior unsecured long-term debt of
the Borrower, then the lowest level (i. e., highest Applicable Facility Fee
Rate) shall be used in determining the Applicable Facility Fee
Rate.

     

    “Applicable
Margin” means,
for any date, the rate per annum set forth in the table below opposite the debt
rating from S&P and Moody’s, respectively, in effect on such date for the
senior unsecured long-term debt of the Borrower, with the higher of the two
ratings to be determinative; provided that if the
debt rating from one of the Rating Agencies is more than one level below the
debt rating from the other Rating Agency, then the debt rating one level below
the higher of the two shall be used in determining the Applicable Margin; provided further that (a) if
only one Rating Agency has a relevant debt rating in effect on such date, then
only such rating shall be used and (b) if neither Rating Agency has a relevant
debt rating in effect on such date, then the lowest level (i.e., highest
Applicable Margin) shall be used:
