GUARANTY

Section 2.01 Guaranty; Limitation of Liability. (a) Guarantor hereby absolutely,
unconditionally and irrevocably guarantees the punctual payment when due,
whether at scheduled maturity or on any date of a required prepayment or by
acceleration, demand or otherwise, of all Obligations of the Borrower
(including, without limitation, any extensions, modifications, substitutions,
amendments, amendments and restatements, replacements or renewals of any or all
of the foregoing Obligations), whether direct or indirect, absolute or
contingent, and whether for principal, interest, premiums, fees, indemnities,
contract causes of action, costs, expenses or otherwise (the Obligations of the
Borrower being the “Guaranteed Obligations” of Guarantor), and agrees to pay any
and all expenses (including, without limitation, all reasonable fees, charges
and disbursements of counsel) incurred by the Administrative Agent or any other
Credit Party in enforcing any rights under this Agreement or any other Loan
Document. Without limiting the generality of the foregoing, Guarantor’s
Obligations hereunder shall extend to all amounts that constitute part of the
Guaranteed Obligations that would be owed by the Borrower to any Credit Party
under or in respect of the Loan Documents but for the fact that they are
unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Borrower.

(b) Guarantor, and the Administrative Agent, for itself and each other Credit
Party, hereby confirms that it is the intention of all such Persons that this
Agreement and the

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

Obligations of Guarantor hereunder not constitute a fraudulent transfer or
conveyance for purposes of Debtor Relief Laws, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar Law to the extent
applicable to this Agreement and the Obligations of Guarantor hereunder. To
effectuate the foregoing intention, the Administrative Agent, the other Credit
Parties and the Guarantor hereby irrevocably agree that the Obligations of
Guarantor under this Agreement at any time shall be limited to the maximum
amount as will result in the Obligations of Guarantor under this Agreement not
constituting a fraudulent transfer or conveyance.

(c) Guarantor hereby unconditionally and irrevocably agrees that in the event
any payment shall be required to be made to any Credit Party under this
Agreement, Guarantor will contribute, to the maximum extent permitted by Law,
such amounts to each other guarantor (if any) so as to maximize the aggregate
amount paid to the Credit Parties under or in respect of the Loan Documents.

Section 2.02 Guaranty Absolute. Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of the Loan
Documents, regardless of any Law now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of any Credit Party with respect
thereto. The Obligations of Guarantor under or in respect of this Agreement are
independent of the Guaranteed Obligations, and a separate action or actions may
be brought and prosecuted against Guarantor to enforce this Agreement,
irrespective of whether any action is brought against the Borrower or whether
the Borrower is joined in any such action or actions. This Agreement is a
present and continuing, absolute and unconditional guarantee of payment when
due, and not of collection, by Guarantor. The liability of Guarantor under this
Agreement shall be irrevocable, absolute and unconditional irrespective of, and
Guarantor hereby irrevocably waives any defenses it may now have or hereafter
acquire in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of any Loan Document or any agreement
or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term
of, all or any of the Obligations of the Borrower under or in respect of the
Loan Documents, or any other amendment or waiver of or any consent to departure
from any Loan Document, including, without limitation, any increase in the
Guaranteed Obligations resulting from the extension of additional credit to the
Parent or any of its Subsidiaries or otherwise;

(c) any taking, release, subordination or amendment or waiver of, or consent to
departure from, any other guarantee (if any), for all or any of the Guaranteed
Obligations;

(d) any change, restructuring or termination of the corporate structure or
existence of the Parent or any of its Subsidiaries or any insolvency,
bankruptcy, reorganization or other similar proceeding under Debtor Relief Laws
affecting the Parent, the Borrower or their assets or any resulting release or
discharge of any Guaranteed Obligation;

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

(e) the existence of any claim, setoff or other right which Guarantor may have
at any time against the Borrower, the Administrative Agent, any Lender or any
other Person, whether in connection herewith or any unrelated transaction;

(f) any provision of applicable Law purporting to prohibit the payment or
performance by the Parent or the Borrower of any of the Obligations of such
Person;

(g) any failure of any Credit Party to disclose to the Parent or the Borrower
any information relating to the business, financial condition, operations,
performance, properties or prospects of the Parent or the Borrower now or
hereafter known to such Credit Party (Guarantor waives any duty on the part of
the Credit Parties to disclose such information);

(h) the failure of any other Person to execute or deliver any other guarantee or
agreement or the release or reduction of liability of Guarantor or other
guarantor (if any) or surety (if any) with respect to the Guaranteed
Obligations; or

(i) any other circumstance (including, without limitation, any statute of
limitations) or any existence of or reliance on any representation by any Credit
Party that might otherwise constitute a defense available to, or a discharge of,
the Parent, the Borrower or any other guarantor or surety.

Section 2.03 Waivers and Acknowledgments.

(a) Guarantor hereby unconditionally and irrevocably waives, to the extent
permitted by applicable Law, promptness, diligence, notice of acceptance,
presentment, demand for performance, notice of nonperformance, default,
acceleration, protest or dishonor and any other notice with respect to any of
the Guaranteed Obligations and this Agreement and any requirement that any
Credit Party protect, secure, perfect or insure any Lien or any property subject
thereto or exhaust any right or take any action against the Borrower or any
other Person.

(b) Guarantor hereby unconditionally and irrevocably waives, to the extent
permitted by applicable Law, any right to revoke this Agreement and acknowledges
that this Agreement is continuing in nature and applies to all Guaranteed
Obligations, whether existing now or in the future.

(c) Guarantor hereby unconditionally and irrevocably waives, to the extent
permitted by applicable Law, (i) any defense arising by reason of any claim or
defense based upon an election of remedies by any Credit Party that in any
manner impairs, reduces, releases or otherwise adversely affects the
subrogation, reimbursement, exoneration, contribution or indemnification rights
of Guarantor or other rights of Guarantor to proceed against the Borrower, any
other guarantor (if any) or any other Person and (ii) any defense based on any
right of setoff or counterclaim against or in respect of the Obligations of
Guarantor hereunder.

(d) Guarantor hereby unconditionally and irrevocably waives any duty on the part
of any Credit Party to disclose to it any matter, fact or thing relating to the
business, financial condition, operations, performance, properties or prospects
of the Borrower or any of its Subsidiaries now or hereafter known by such Credit
Party.

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

(e) Guarantor acknowledges that it will receive substantial direct and indirect
benefits from the financing arrangements contemplated by the Loan Documents and
that the waivers set forth in Section 2.02 and this Section 2.03 are knowingly
made in contemplation of such benefits.

Section 2.04 Subordination. (a) Guarantor hereby unconditionally and irrevocably
agrees not to exercise any rights that it may now have or hereafter acquire
against the Borrower or any other insider guarantor (if any) that arise from the
existence, payment, performance or enforcement of Guarantor’s Obligations under
or in respect of this Agreement or any other Loan Document, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution
(pursuant to Section 2.01(c) or otherwise) or indemnification and any right to
participate in any claim or remedy of any Credit Party against the Borrower,
Guarantor or any other insider guarantor (if any) whether or not such claim,
remedy or right arises in equity or under contract, statute or common law,
including, without limitation, the right to take or receive from the Borrower or
any other insider guarantor (if any), directly or indirectly, in cash or other
property or by setoff or in any other manner, payment or security on account of
such claim, remedy or right without the prior written consent of the
Administrative Agent, unless and until the Termination Date has occurred.

(b) Guarantor hereby agrees that any and all debts, liabilities and other
obligations owed to it by the Borrower, including pursuant to Section 2.01(c)
(collectively, the “Subordinated Obligations”), are hereby subordinated to the
prior payment in full in cash of the Obligations of the Borrower under the Loan
Documents to the extent and in the manner hereinafter set forth in this
Section 2.04(b):

(A) Except during the continuance of an Event of Default (including the
commencement and continuation of any proceeding under any Debtor Relief Law
relating to the Borrower), Guarantor may receive regularly scheduled payments
from the Borrower on account of the Subordinated Obligations. After the
occurrence and during the continuance of any Event of Default (including the
commencement and continuation of any proceeding under any Debtor Relief Law
relating to the Borrower), however, unless the Administrative Agent otherwise
agrees in writing, Guarantor shall not demand, accept or take any action to
collect any payment on account of the Subordinated Obligations.

(B) In any proceeding under any Debtor Relief Law relating to the Borrower,
Guarantor agrees that, unless the Administrative Agent otherwise agrees in
writing, the Credit Parties shall be entitled to receive payment in full in cash
of all Obligations (including all interest and expenses accruing after the
commencement of a proceeding under any Debtor Relief Law, whether or not
constituting an allowed claim in such proceeding (“Post Petition Interest”)) of
the Borrower before Guarantor receives payment of any Subordinated Obligations
of the Borrower.

(C) After the occurrence and during the continuance of any Event of Default
(including the commencement and continuation of any proceeding under any Debtor
Relief Law relating to the Borrower), Guarantor shall, if the Administrative
Agent so requests, collect, enforce and receive payments on account of any
Subordinated

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

Obligations due to Guarantor from the Borrower as trustee for the Credit Parties
and deliver such payments to the Administrative Agent for application to the
Guaranteed Obligations (including all Post Petition Interest), together with any
necessary endorsements or other instruments of transfer, but without reducing or
affecting in any manner the liability of Guarantor under the other provisions of
this Agreement.

(D) After the occurrence and during the continuance of any Event of Default
(including the commencement and continuation of any proceeding under any Debtor
Relief Law relating to the Borrower), the Administrative Agent is authorized and
empowered (but without any obligation to so do), in its discretion, (A) in the
name of Guarantor, to collect and enforce, and to submit claims in respect of,
Subordinated Obligations due to Guarantor and to apply any amounts received
thereon to the Guaranteed Obligations (including any and all Post Petition
Interest), and (B) to require Guarantor (1) to collect and enforce, and to
submit claims in respect of, Subordinated Obligations due to Guarantor and
(2) to pay any amounts received on such obligations to the Administrative Agent
for application to the Guaranteed Obligations (including any and all Post
Petition Interest).

(c) If any amount shall be paid to Guarantor in violation of this Section 2.04
at any time prior to the Termination Date, such amount shall be received and
held in trust for the benefit of the Credit Parties, shall be segregated from
other property and funds of Guarantor and shall forthwith be paid or delivered
to the Administrative Agent in the same form as so received (with any necessary
endorsement or assignment) to be credited and applied to the Guaranteed
Obligations and all other amounts payable under this Agreement, whether matured
or unmatured, in accordance with the terms of the Loan Documents.

(d) If the Termination Date shall have occurred, the Administrative Agent will,
at Guarantor’s request and expense, execute and deliver to Guarantor appropriate
documents, without recourse and without representation or warranty, necessary to
evidence the transfer by subrogation to Guarantor of an interest in the
Guaranteed Obligations resulting from any payment made by Guarantor pursuant to
this Agreement.

Section 2.05 Payments Free and Clear of Taxes, Etc. (a) Any and all payments
made by Guarantor under or in respect of this Agreement or any other Loan
Document shall be made, in accordance with Section 3.01 of the Credit Agreement,
free and clear of and without reduction or withholding for any Indemnified Taxes
(including Other Taxes), provided that if Guarantor shall be required by any
Laws to deduct any Indemnified Taxes (including 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 2.05), each of the Administrative Agent or applicable
Lender, as the case may be, receives an amount equal to the sum it would have
received had no such deductions been required to be made, (ii) Guarantor shall
make such deductions, and (iii) Guarantor shall timely pay the full amount
deducted to the relevant Governmental Authority in accordance with Law.

(b) Without limiting the provisions of subsection (a) above, Guarantor shall
timely pay any Other Taxes that arise from any payment made by or on behalf of
Guarantor under or in respect of this Agreement or from the execution, delivery,
performance, enforcement or registration of, or otherwise with respect to, this
Agreement to the relevant Governmental Authority in accordance with Law.

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

(c) Guarantor shall indemnify the Administrative Agent and each Lender within 10
days after demand therefor, for the full amount of Indemnified Taxes or Other
Taxes (including any Indemnified Taxes or Other Taxes imposed or asserted or
attributable to amounts payable under this Section) paid by the Administrative
Agent or such Lender, as the case may be, 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 Guarantor by a Lender (with a copy to
the Administrative Agent), or by the Administrative Agent on its own behalf or
on behalf of a Lender, shall be conclusive absent manifest error.

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