#PageNum#

SECTION 2.2.    Loans and Borrowings. (a)  Each Revolving Loan shall be made as
part of a Borrowing consisting of Revolving Loans made by the Lenders ratably in
accordance with their respective Commitments. The failure of any Lender to make
any Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder; provided that the Commitments of the Lenders are several
and no Lender shall be responsible for any other Lender’s failure to make Loans
as required.
(b)    At the time that each Revolving Borrowing is made, such Borrowing shall
be in an amount that is not less than $500,000; provided that a Revolving
Borrowing may be in an aggregate amount that is equal to the entire unused
balance of the total Commitments.
SECTION 2.3.    Requests for Revolving Borrowings. To request a Revolving
Borrowing, the Borrower shall notify the Administrative Agent of such request by
telephone, not later than 11:00 a.m., New York City time, one Business Day
before the date of the proposed Borrowing. Each such telephonic Borrowing
Request shall be irrevocable and shall be confirmed promptly by hand delivery or

required by the Administrative Agent and signed by the Borrower. Each such
telephonic and written Borrowing Request shall specify the following information
in compliance with SECTION 2.2:
(i)    the aggregate amount of the requested Borrowing;
(ii)    the date of such Borrowing, which shall be a Business Day; and
(iii)    the location and number of the account to which funds are to be
disbursed, which shall comply with the requirements of SECTION 2.4.
Promptly following receipt of a Borrowing Request in accordance with this
Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender’s Loan to be made as part of the
requested Borrowing.
SECTION 2.4.    Funding of Borrowings. Each Lender shall make each Loan to be
made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds by 12:00 noon, New York City time, to the account of
the Administrative Agent most recently designated by it for such purpose by
notice to the Lenders. The Administrative Agent will make such Loans available
to an account of the Borrower designated by the Borrower in the applicable
Borrowing Request.
SECTION 2.5.    Termination and Reduction of Commitments. (a) Unless previously
terminated, the Commitments shall terminate on the Maturity Date.
(b)    The Borrower may at any time terminate, or from time to time reduce, the
Commitments; provided that (i) each reduction of the Commitments shall be in an
amount that is an integral multiple of, and not less than, $100,000 and (ii) the
Borrower shall not terminate or reduce the Commitments if, after giving effect
to any concurrent prepayment of the Loans in accordance with SECTION 2.7, the
aggregate amount of outstanding Revolving Loans would exceed the total
Commitments.
(c)    The Borrower shall notify the Administrative Agent of any election to
terminate or reduce the Commitments under paragraph (b) of this Section at least
three Business Days prior to the effective date of such termination or
reduction, specifying such election and the effective date thereof. Promptly
following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant
to this Section shall be irrevocable; provided that a notice of termination of
the Commitments delivered by the Borrower may state that such

--------------------------------------------------------------------------------

#PageNum#

notice is conditioned upon the effectiveness of other credit facilities, in
which case such notice may be revoked by the Borrower (by notice to the
Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied. Any termination or reduction of the Commitments
shall be permanent. Each reduction of the Commitments shall be made ratably
among the Lenders in accordance with their respective Commitments.
SECTION 2.6.    Repayment of Loans; Evidence of Debt; Extension of Maturity
Date. (a) The Borrower hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Revolving Loan on the Maturity Date.
(b)    Each Lender shall maintain an account or accounts evidencing the
indebtedness of the Borrower to such Lender resulting from each Loan made by
such Lender, including the amounts of principal and interest payable and paid to
such Lender from time to time hereunder.
(c)    The Administrative Agent shall maintain accounts in which it shall record
(i) the amount of each Loan made hereunder, the date of such Loan and the Class
thereof, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iii) the
amount of any sum received by the Administrative Agent hereunder for the account
of the Lenders and each Lender’s share thereof.
(d)    The entries made in the accounts maintained pursuant to paragraph (b)
or (c) of this Section shall be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with the terms of this Agreement.
(e)    Any Lender may request that Loans made by it be evidenced by a promissory
note (a “Note”). In such event, the Borrower shall prepare, execute and deliver
to such Lender a promissory note payable to the order of such Lender (or, if
requested by such Lender, to such Lender and its registered assigns) and in a
form approved by the Administrative Agent. Thereafter, the Loans evidenced by
such promissory note and interest thereon shall at all times (including after
assignment pursuant to SECTION 9.4) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).
(f)    So long as no Default or Event of Default has occurred and is continuing
, the Borrower may extend the Maturity Date for six months on a single occasion,
by providing written notice to the Administrative Agent at least 30 days but no
more than 90 days prior to the Maturity Date. If on the initial Maturity Date
(i) no Default or Event of Default exists and is continuing, and (ii) the
Borrower has given written notice to the Administrative Agent of such election
to extend the Maturity Date within the time frame set forth in this SECTION
2.6(f), the Maturity Date shall be extended to June 30, 2007.
SECTION 2.7.    Prepayment of Loans. (a) The Borrower shall have the right at
any time and from time to time to prepay any Borrowing in whole or in part,
subject to prior notice in accordance with paragraph (b) of this Section.
(b)    The Borrower shall notify the Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder not later than 11:00 a.m.,
New York City time, one Business Day before the date of prepayment. Each such
notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Borrowing or portion thereof to be prepaid; provided
that, if a notice of prepayment is given in connection with a conditional notice
of termination of the Commitments

BUSDOCS/1480716.6

--------------------------------------------------------------------------------

#PageNum#

as contemplated by SECTION 2.5, then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with SECTION 2.5. Promptly
following receipt of any such notice relating to a Revolving Borrowing, the
Administrative Agent shall advise the Lenders of the contents thereof. Each
partial prepayment of any Revolving Borrowing shall be in an amount that would
be permitted in the case of an advance of a Revolving Borrowing as provided in
SECTION 2.2. Each prepayment of a Revolving Borrowing shall be applied ratably
to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied
by accrued interest to the extent required by SECTION 2.9.
SECTION 2.8.    Fees. The Borrower agrees to pay to the Administrative Agent for
the account of each Lender a set-up fee, payable in installments on the date of
each Borrowing, equal to, in each case, the amount of 1% of the positive
difference, if any, between (a) the outstanding principal amount of the Loans
after giving effect to such Borrowing and (b) the Maximum Outstanding Amount. In
no event shall the total amount of such set-up fee be greater than $200,000 in
the aggregate.
SECTION 2.9.    Interest. (a) The Loans comprising each Borrowing shall bear
interest for each Interest Period at a rate per annum equal to the LIBOR Rate
plus five percent (5%).
(b)    Notwithstanding the foregoing, if any principal of or interest on any
Loan or any fee or other amount payable by the Borrower hereunder is not paid
when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to 2% plus the rate otherwise applicable to Loans as provided in
the preceding paragraph of this Section.
(c)    Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date and upon termination of the Commitments; provided that (i)
interest accrued pursuant to paragraph (b) of this Section shall be payable on
demand and (ii) in the event that the Borrower has insufficient cash available
on any Interest Payment Date to pay both required interest and required
dividends payable on the next dividend payment date to the holders of the
Guarantor’s preferred stock, the Borrower may request a Loan on such Interest
Payment Date in accordance with SECTION 2.3 in the amount of all accrued and
unpaid interest on the Loans, and the proceeds of such Loans shall be used to
pay in full all such accrued and unpaid interest. If on any Interest Payment
Date the Borrower is not able to make a payment of interest in accordance with
clause (ii) of the proviso to this paragraph (c) due to a lack of availability
of the Commitments of the Lenders, the Commitment of each of the Lenders shall
be increased in accordance with its Applicable Percentages to an amount equal to
its share of the amount by which any unpaid accrued interest on such Interest
Payment Date exceeds the current Commitments of the Lenders; provided that the
Borrower may not make any Borrowings when the aggregate amount of the
Commitments exceeds $20,000,000 for any purposes other than the payment of
interest hereunder.
(d)    All interest hereunder shall be computed on the basis of a year of 365
days (or 366 days in a leap year), and shall be payable for the actual number of
days elapsed (including the first day but excluding the last day). The interest
rate shall be determined by the Administrative Agent, and such determination
shall be conclusive absent manifest error.
SECTION 2.10.    Increased Costs. (a) If any Change in Law shall:
(i)    impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit
extended by, any Lender; or

BUSDOCS/1480716.6

--------------------------------------------------------------------------------

#PageNum#

(ii)    impose on any Lender or the London interbank market any other condition
affecting this Agreement;
and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Loan (or of maintaining its obligation to
make any such Loan) or to increase the cost to such Lender or to reduce the
amount of any sum received or receivable by such Lender hereunder (whether of
principal, interest or otherwise), then the Borrower will pay to such Lender
such additional amount or amounts as will compensate such Lender for such
additional costs incurred or reduction suffered.
(b)    If any Lender determines that any Change in Law 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 or the Loans made by such Lender 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)    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 paragraph (a) or (b) of this Section shall be delivered to the
Borrower and shall 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)    Failure or delay on the part of any Lender to demand compensation
pursuant to 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 this Section for any increased costs or
reductions incurred more than 270 days 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;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 270-day period referred to above shall be
extended to include the period of retroactive effect thereof.
SECTION 2.11.    Taxes. (a) Any and all payments by or on account of any
obligation of the Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or 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 pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.
(b)    In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.
(c)    The Borrower shall indemnify the Administrative Agent and each Lender,
within 10 days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender, as the case may be, on or with respect to any payment by or on account
of any obligation of the Borrower hereunder (including Indemnified Taxes or
Other Taxes

imposed or asserted on or attributable to amounts payable under this Section)
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 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 or by the Administrative Agent on its own behalf or on
behalf of a Lender, shall be conclusive absent manifest error.
(d)    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)    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
located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate.
(f)    If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund 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 2.11, it shall pay
over such refund to the Borrower (but only to the extent of indemnity payments
made, or additional amounts paid, by the Borrower under this SECTION 2.11 with
respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent or such Lender and without
interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund); 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 to such Governmental Authority. This Section 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 which it deems confidential) to
the Borrower or any other Person.
SECTION 2.12.    Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
(a) The Borrower shall make each payment required to be made by it hereunder
(whether of principal, interest, fees, or of amounts payable under SECTION 2.10,
SECTION 2.11, or otherwise) prior to 12:00 noon, New York City time, on the date
when due, in immediately available funds, without set-off or counterclaim. Any
amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at One Beacon Street,
Boston, Massachusetts or as the Administrative shall otherwise designate to the
Borrower in writing, except that payments pursuant to SECTION 2.10, SECTION 2.11
and SECTION 9.3 shall be made directly to the Persons entitled thereto. The
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following
receipt thereof. If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding
Business Day, and, in the case of any payment accruing interest, interest
thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

--------------------------------------------------------------------------------

#PageNum#

(b)    If at any time insufficient funds are received by and available to the
Administrative Agent to pay fully all amounts of principal, interest and fees
then due hereunder, such funds shall be applied (i) first, towards payment of
interest and fees then due hereunder, ratably among the parties entitled thereto
in accordance with the amounts of interest and fees then due to such parties,
and (ii) second, towards payment of principal then due hereunder, ratably among
the parties entitled thereto in accordance with the amounts of principal then
due to such parties.
(c)    If any Lender shall, by exercising any right of set-off or counterclaim
or otherwise, obtain payment in respect of any principal of or interest on any
of its Revolving Loans resulting in such Lender receiving payment of a greater
proportion of the aggregate amount of its Revolving Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Revolving Loans of other Lenders to the extent necessary
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 Revolving Loans; 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 paragraph shall not be construed to apply to any payment made
by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to the Borrower or any Subsidiary or Affiliate thereof
(as to which the provisions of this paragraph 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 set-off 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.
(d)    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 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 Federal Funds Effective Rate.
(e)    If any Lender shall fail to make any payment required to be made by it
pursuant to SECTION 2.12(d), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender
to satisfy such Lender’s obligations under such Sections until all such
unsatisfied obligations are fully paid.
SECTION 2.13.    Mitigation Obligations; Replacement of Lenders. (a) If any
Lender requests compensation under SECTION 2.10, 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 2.11, then such Lender shall use
reasonable efforts to designate a different lending office for funding or
booking its Loans hereunder or to assign its 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 2.10 or SECTION 2.11, as the case may be, in the
future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not

#PageNum#

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)    If any Lender requests compensation under SECTION 2.10, 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 2.11,
or if any Lender defaults in its obligation to fund Loans hereunder, 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
SECTION 9.4), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) 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,
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) and
(iii) in the case of any such assignment resulting from a claim for compensation
under SECTION 2.10, such assignment will result in a reduction in such
compensation or payments. A Lender shall not be required to make any such
assignment and 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.

GUARANTY
SECTION 4A.1  Guaranty of Payment and Performance. Subject to SECTION 4A.7, the
Guarantor hereby absolutely, irrevocably and unconditionally guarantees to each
Lender the prompt payment and performance of the Obligations in full when due
(whether at stated maturity, as a mandatory prepayment, by acceleration or
otherwise). This Guaranty is a guaranty of payment and not of collection and is
a continuing guaranty and shall apply to all Obligations whenever arising.
SECTION 4A.2  Obligations Unconditional. The obligations of the Guarantor
hereunder are absolute, irrevocable and unconditional, irrespective of the
value, genuineness, validity, regularity or enforceability of any of the Loan
Documents or any other agreement or instrument referred to therein, to the
fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever which might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor. The Guarantor agrees that this
Guaranty may be enforced by the Lenders without the necessity at any time of
resorting to or exhausting any other security or collateral and without the
necessity at any time of having recourse to any notes issued hereunder or any
other of the Loan Documents or any collateral, if any, hereafter securing the
Obligations or otherwise and the Guarantor hereby waives the right to require
the Lenders to proceed against the Borrower or any other Person (including a
co-guarantor) or to require the Lenders to pursue any other remedy or enforce
any other right. The Guarantor further agrees that it shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower for
amounts paid under this Guaranty until such time as the Lenders have been paid
in full, all Commitments under this Agreement have been terminated and no Person
or Governmental Authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received under
the Loan Documents. The Guarantor further agrees that nothing contained herein
shall prevent the Lenders from suing on the Notes issued hereunder or any of the
other Loan Documents or foreclosing any security interest in or Lien on any
collateral, if any, securing the Obligations or from exercising any other rights
available to any of them under this Agreement, the Notes, any of the other Loan
Documents, or any other instrument of security, if any, and the exercise of any
of the aforesaid rights and the completion of any foreclosure proceedings shall
not constitute a discharge of any of the Guarantor’s obligations hereunder; it
being the purpose and intent of the Guarantor that its obligations hereunder
shall be absolute, independent, irrevocable and unconditional under any and all
circumstances. Neither the Guarantor’s obligations under this Guaranty nor any
remedy for the enforcement thereof shall be impaired, modified, changed or
released in any manner whatsoever by an impairment, modification, change,
release or limitation of the liability of the Borrower or by reason of the
bankruptcy or insolvency of the Borrower. The Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof of reliance of by the Administrative Agent or any Lender
upon this Guaranty or acceptance of this Guaranty. The Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon this Guaranty. All
dealings between the Borrower and the Guarantor, on the one hand, and the
Administrative Agent and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon this
Guaranty. The Guarantor further agrees to all rights of set-off as set forth in
SECTION 9.8.
SECTION 4A.3  Modifications. The Guarantor agrees that (a) all or any part of
the security now or hereafter held for the Obligations, if any, may be
exchanged, compromised or surrendered from time to time; (b) the Lenders shall

interests, liens or encumbrances now or hereafter held, if any, for the
Obligations or the properties subject thereto; (c) the time or place of payment
of the Obligations may be changed or extended, in whole or in part, to a time
certain or otherwise, and may be renewed or accelerated, in whole or in part;
(d) the

BUSDOCS/1480716.6

#PageNum#

Borrower and any other party liable for payment under the Loan Documents may be
granted indulgences generally; (e) any of the provisions of the Notes issued
hereunder or any of the other Loan Documents may be modified, amended or waived;
(f) any party (including any co-guarantor) liable for the payment thereof may be
granted indulgences or be released; and (g) any deposit balance for the credit
of the Borrower or any other party liable for the payment of the Obligations or
liable upon any security therefor may be released, in whole or in part, at,
before or after the stated, extended or accelerated maturity of the Obligations,
all without notice to or further assent by the Guarantor, which shall remain
bound thereon, notwithstanding any such exchange, compromise, surrender,
extension, renewal, acceleration, modification, indulgence or release.
SECTION 4A.4  Waiver of Rights. The Guarantor expressly waives to the fullest
extent permitted by applicable law: (a) notice of acceptance of this Guaranty by
the Lenders and of all extensions of credit to the Borrower by the Lenders; (b)
presentment and demand for payment or performance of any of the Obligations; (c)
protest and notice of dishonor or of default (except as specifically required in
this Agreement) with respect to the Obligations or with respect to any security
therefor; (d) notice of the Lenders obtaining, amending, substituting for,
releasing, waiving or modifying any security interest, lien or encumbrance, if
any, hereafter securing the Obligations, or the Lenders’ subordinating,
compromising, discharging or releasing such security interests, liens or
encumbrances, if any; (e) all other notices to which the Guarantor might
otherwise be entitled; and (f) the benefit of any laws that exonerate or limit
the liability of guarantors or sureties, and any defenses provided by these
laws.
SECTION 4A.5  Reinstatement. The obligations of the Guarantor under this
Guaranty shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Person in respect of the Obligations
is rescinded or must be otherwise restored by any holder of any of the
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and the Guarantor agrees that it will indemnify the
Administrative Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, reasonable fees of counsel) incurred by
the Administrative Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.
SECTION 4A.6  Remedies. The Guarantor agrees that, as amongst the Guarantor, the
Administrative Agent and the Lenders, the Obligations may be declared to be
forthwith due and payable as provided in ARTICLE VII (and shall be deemed to
have become automatically due and payable in the circumstances provided in
ARTICLE VII) notwithstanding any stay, injunction or other prohibition
preventing such declaration (or preventing such Obligations from becoming
automatically due and payable) as against any other Person and that, in the
event of such declaration (or such Obligations being deemed to have become
automatically due and payable), such Obligations (whether or not due and payable
by any other Person) shall forthwith become due and payable by the Guarantor.
SECTION 4A.7  Limitation of Guaranty. It is the intention and agreement of the
Guarantor, the Administrative Agent and the Lenders that the obligations of the
Guarantor hereunder shall be valid and enforceable against the Guarantor to the
maximum extent permitted by applicable law. Notwithstanding any provision to the
contrary contained herein or in any of the other Loan Documents, to the extent
the obligations of the Guarantor shall be adjudicated or declared to be invalid
or unenforceable for any reason (including, without limitation, because of any
applicable state or federal law relating to fraudulent conveyances or transfers)
then the obligations of the Guarantor hereunder shall be limited to the maximum
amount that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

ratios set forth in SECTION 6.1(a) as of the date of each Borrowing. The

the most recently available financial statements, and adding thereto any
Indebtedness incurred since the date of such financial statement (less any
Indebtedness repaid, retired, or forgiven during such period) and adding thereto
the value of such assets (determined at cost) acquired with such Indebtedness to
Total Value and, if applicable (less the value of any assets sold during such
period). The Borrower shall deliver an officer’s certificate, signed by the
Financial Officer of the Borrower, certifying that the pro forma calculations as
of the date of such Borrowing demonstrate the Borrower’s compliance with the
covenants and financial ratios set forth in SECTION 6.1(a).

transaction in which the Borrower is the surviving Person, (ii) any Person may
merge into any Subsidiary in a transaction in which the surviving entity is a

ARTICLE VIII    

THE ADMINISTRATIVE AGENT
Each of the Lenders hereby irrevocably appoints the Administrative Agent as its
agent and authorizes the Administrative Agent to take such actions on its behalf
and to exercise such powers as are delegated to the Administrative Agent by the
terms hereof, together with such actions and powers as are reasonably incidental
thereto.
The entity 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 such
entity and its Affiliates may lend money to and generally engage in any kind of
business with the Guarantor, the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.
The Administrative Agent shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing,
(a) the Administrative Agent shall not be subject to any fiduciary or other
implied duties, regardless of whether a Default has occurred and is continuing,
(b) the Administrative Agent shall not have any duty to take any discretionary
action or exercise any discretionary powers, except discretionary rights and
powers expressly contemplated hereby that the Administrative Agent is required
to exercise in writing as directed by the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary under the circumstances as
provided in SECTION 9.2), and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to the Guarantor,
the Borrower or any of its Subsidiaries that is communicated to or obtained by
the entity serving as 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 with the consent or at the request of the Required Lenders (or
such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in SECTION 9.2) or 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 written notice thereof is
given to the Administrative Agent by the Borrower or a Lender, and 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, (ii) the contents of any certificate, report or
other document delivered hereunder or in connection herewith, (iii) the
performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein, (iv) the validity, enforceability, effectiveness or
genuineness of this Agreement or any other 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.
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 believed by it to be genuine
and to have been signed or sent 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 be made by the proper Person, and shall not incur any liability for
relying thereon. 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.

The Administrative Agent may perform any and all its duties and exercise its
rights and powers 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 its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions of the preceding
paragraphs 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.
Subject to the appointment and acceptance of a successor Administrative Agent as
provided in this paragraph, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower. Upon any such resignation, the Required
Lenders shall have the right, in consultation with the Borrower, to appoint a
successor. If no 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. Upon the acceptance of its appointment as Administrative
Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. 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 Administrative Agent’s resignation hereunder, the provisions of this
Article and SECTION 9.3 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
while it was acting as Administrative Agent.
Each Lender acknowledges that it has, independently and without reliance upon
the Administrative Agent or any other Lender 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 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 related agreement or any
document furnished hereunder or thereunder.

the provisions of this Agreement shall be deemed to have been given on the date

SECTION 9.2.    Waivers; Amendments. (a) No failure or delay by the
Administrative Agent or any Lender in exercising any right or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power. The rights and remedies of the
Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the
Administrative Agent, any Lender may have had notice or knowledge of such
Default at the time.
(b)    Neither this Agreement nor any provision hereof may be waived, amended or
modified except pursuant to an agreement or agreements in writing entered into
by the Borrower and the Required Lenders or by the Borrower and the

written consent of such Lender except as expressly provided in SECTION 2.9(c) as

than as expressly permitted in SECTION 2.6(f) as in effect on the date hereof,
(iv) change SECTION 2.12(b) or SECTION 2.12(c) in a manner that would alter the
pro rata sharing of payments required thereby, without the written consent of
each Lender, or (v) change any of the provisions of this Section or the
definition of “Required Lenders” or any other provision hereof specifying the
number or percentage of Lenders required to waive, amend or modify any rights
hereunder or make any determination or grant any consent hereunder, without the
written consent of each Lender; provided further that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative
Agent hereunder without the prior written consent of the Administrative Agent.
SECTION 9.3.    Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay

fees, charges and disbursements of any counsel for any Indemnitee, incurred by
or asserted against any Indemnitee arising out of, in connection with, or as a

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 resulted from the gross
negligence or willful misconduct of such Indemnitee.
(c)    To the extent that the Borrower fails to pay any amount required to be
paid by it to the Administrative Agent under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Administrative Agent 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 in its capacity as such.
(d)    To the 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 or any agreement or instrument contemplated hereby, the Transactions,
any Loan or the use of the proceeds thereof.
(e)    All amounts due under this Section shall be payable promptly after
written demand therefor.
SECTION 9.4.    Successors and Assigns. (a) 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 (i) the Borrower
may not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender (and any attempted assignment
or transfer by the Borrower without such consent shall be null and void) and
(ii) no Lender may assign or otherwise transfer its rights or obligations
hereunder except in accordance with this Section. Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than

each of the Administrative Agent and the Lenders) any legal or equitable right,
remedy or claim under or by reason of this Agreement.
(b)    (i) Subject to the conditions set forth in paragraph (b)(ii) below, any
Lender may 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) with the prior written consent (such
consent not to be unreasonably withheld) of:
(A) the Borrower, provided that no consent of the Borrower shall be required for
an assignment to a Lender, an Affiliate of a Lender or, if an Event of Default
has occurred and is continuing, any other assignee; and
(B) the Administrative Agent.
(ii)    Assignments shall be subject to the following additional conditions:
(A)    except in the case of an assignment to a Lender or an Affiliate of a
Lender or an assignment of the entire remaining amount of the assigning Lender’s
Commitment or Loans of any Class, the amount of the Commitment or 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) shall not be less than $5,000,000 unless each of the
Borrower and the Administrative Agent otherwise consent, provided that no such
consent of the Borrower shall be required if an Event of Default under clause
(a), (b), (h) or (i) of Article VII has occurred and is continuing;
(B)    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,
provided that this clause shall not be construed to prohibit the assignment of a
proportionate part of all the assigning Lender’s rights and obligations in
respect of one Class of Commitments or Loans;
(C)    the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Assumption; and
(D)    the assignee, if it shall not be a Lender, shall provide to the
Administrative Agent a notice address for such Lender.
(iii)    Subject to acceptance and recording thereof pursuant to
paragraph (b)(iv) of this Section, from and after the effective date specified
in each Assignment and Assumption the assignee thereunder shall be a party
hereto 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 SECTION 2.10, SECTION 2.11 and SECTION 9.3). Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this SECTION 9.4 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 paragraph (c)
of this Section.
(iv)    The Administrative Agent, acting for this purpose as an agent of the
Borrower, shall maintain at one of its offices 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 Commitment of, and principal amount of the
Loans and 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 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.
(v)    Upon its receipt of a duly completed Assignment and Assumption executed
by an assigning Lender and an assignee, the assignee’s notice address
information (unless the assignee shall already be a Lender hereunder), the
processing and recordation fee referred to in paragraph (b) of this Section and
any written consent to such assignment required by paragraph (b) of this
Section, the Administrative Agent shall accept such Assignment and Assumption
and record the information contained therein in the Register. No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this paragraph.
(c)    (i) Any Lender may, without the consent of the Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a “Participant”) in all or a portion of such Lender’s rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it); provided that (A) such Lender’s obligations under this Agreement
shall remain unchanged, (B) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations and (C) the
Borrower, the Administrative Agent and the other 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, modification or waiver
described in the first proviso to SECTION 9.2(b) that affects such Participant.
Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each
Participant shall be entitled to the benefits of SECTION 2.10, and SECTION 2.11
to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of SECTION 9.8 as
though it were a Lender, provided such Participant agrees to be subject to
SECTION 2.12(c) as though it were a Lender.
(ii)    A Participant shall not be entitled to receive any greater payment under
SECTION 2.10 or SECTION 2.11 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 2.11 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 2.11(e) as
though it were a Lender.

(d)    Any Lender may at any time pledge or assign a security interest in all or
any portion of its rights under this Agreement to secure obligations of such
Lender, including without limitation any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section shall not apply to any
such pledge or assignment of a security interest; provided that no such pledge
or assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.
SECTION 9.5.    Survival. All covenants, agreements, representations and
warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any
Loans, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended hereunder, and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loan or
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Commitments have not expired or terminated. The
provisions of SECTION 2.10, SECTION 2.11 and Section 9.3 and Article VIII shall
survive and remain in full force and effect regardless of the consummation of
the transactions contemplated hereby, the repayment of the Loans, the expiration
or termination the Commitments or the termination of this Agreement or any
provision hereof.
SECTION 9.6.    Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative
Agent 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 4.1, 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 which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. 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.
SECTION 9.7.    Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.
SECTION 9.8.    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 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 obligations at any time owing
by such Lender or Affiliate to or for the credit or the account of the Borrower
against any of and all the obligations of the Borrower now or hereafter existing
under this Agreement held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender under this Section are
in addition to other rights and remedies (including other rights of setoff)
which such Lender may have.

from any thereof, in any action or proceeding arising out of or relating to this

now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement 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 law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

in the manner provided for notices in Section 9.1. Nothing in this Agreement

CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK

Agreement, (e) in connection with the exercise of any remedies hereunder or any
suit, action or proceeding relating to this Agreement or the enforcement of
rights hereunder, (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 (i) becomes publicly available other than as a
result of a breach of this Section or (ii) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower. For the purposes of this Section, “Information” means
all information received from the Borrower relating to the Borrower or its
business, other than any such information that is available to the
Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information received
from the Borrower 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.
SECTION 9.13.    USA PATRIOT Act. Each Lender hereby notifies the Borrower and
the Guarantor that pursuant to the requirements of the USA Patriot Act (Title
III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is
required to obtain, verify and record information that identifies the Borrower,
which information includes the name and address of the Borrower and other
information that will allow such Lender to identity the Borrower in accordance
with the Act.
SECTION 9.14.    Interest Rate Limitation. Notwithstanding anything herein to
the contrary, if at any time the interest rate applicable to any Loan, together
with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively the “Charges”), shall exceed the maximum
lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken,
received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.
SECTION 9.15.    Limitation of Liability. None of the Persons holding Equity
Interests in any of the Lenders or any Related Parties thereof (collectively,
“Upstream Persons”), other than such Lender, shall be personally liable for the
Commitments or any other amounts due hereunder or under any other Loan Document
from such Lender or for the performance of any obligations of any Lender
hereunder or thereunder. The sole recourse of the Borrower or the Guarantor for
satisfaction of the Commitments and obligations of the Lenders shall be against
such Lenders and its assets (and not against any assets or property of any
Upstream Persons). In the event that a Lender breaches its obligations
hereunder, no action shall be brought against any such Upstream Person.
