ARTICLE 2.  UNLIMITED GUARANTY.

         2.01 Guaranty of Obligations. The Guarantors, jointly and severally,
hereby absolutely and unconditionally guaranty to the Administrative Agent, for
the benefit of the Administrative Agent and the Banks, the prompt and complete
payment in cash when due and payable (whether at the stated or accelerated
maturity thereof, or otherwise) of all Obligations of the Borrower to the
Administrative Agent and the Banks and the performance of the Borrower's
covenants under all Loan Documents and instruments evidencing any of the
Obligations, or under which the Obligations may have been issued, created,
assumed or guaranteed, and all expenses incurred in collecting the same, all of
which shall conclusively be deemed to have been incurred in reliance upon this
Guaranty.

                                      -2-
<PAGE>
This Guaranty is a guaranty of payment and not of collection, and is absolute
and unconditional. In the event that any part of the Obligations shall not have
been so paid in full when due and payable, the Guarantors will, immediately upon
notice from the Administrative Agent or, without notice, immediately upon the
occurrence of an Event of Default under Section 7.1(f) or (g) of the Loan
Agreement, pay or cause to be paid to the Administrative Agent the unpaid amount
of the Obligations which are then due and payable. The obligations of each of
the Guarantors hereunder shall not be affected by the invalidity,
unenforceability or irrecoverability of any of the Obligations as against any of
the other Guarantors or as against any other Obligor. For purposes hereof, the
Obligations shall be due and payable when and as the same shall be due and
payable under the terms of the Loan Agreement or any other Loan Document
notwithstanding the fact that the collection or enforcement thereof may be
stayed or enjoined under the Federal Bankruptcy Code or other applicable law.

         2.02. Continuing Obligations. The Guarantors acknowledge that the
Administrative Agent and the Banks, in determining to enter into the Loan
Agreement, have relied upon the fact that this Guaranty constitutes the
continuing and irrevocable agreement of each of the Guarantors, and each
Guarantor agrees that its obligations hereunder may not be revoked in whole or
in part. The obligations of the Guarantors hereunder shall terminate when the
commitment of the Administrative Agent and the Banks to extend credit under the
Loan Agreement shall have terminated and all of the Obligations have been paid
in full in cash and discharged; provided, however, that:

                  (a) if a claim is made against the Administrative Agent or the
Banks at any time for repayment or recovery of any amounts or any property
received by the Administrative Agent or the Banks from any source on account of
any of the Obligations and the Administrative Agent or the Banks repay or return
any amounts or property so received (including interest thereon to the extent
required to be paid by the Administrative Agent or the Banks) or

                  (b) if the Administrative Agent or the Banks become liable for
any part of such claim by reason of (i) any judgment or order of any court or
administrative authority having competent jurisdiction, or (ii) any settlement
or compromise of any such claim, then the Guarantors shall remain liable under
this Guaranty for the amounts so repaid or property so returned or the amounts
for which the Administrative Agent or the Banks become liable (such amounts
being deemed part of the Obligations) to the same extent as if such amounts or
property had never been received by the Administrative Agent or the Banks,
notwithstanding any termination hereof or the cancellation of any instrument or
agreement evidencing any such Obligations. Not later than five days after
receipt of notice from the Administrative Agent, the Guarantors shall pay to the
Administrative Agent an amount equal to the amount of such repayment or return
for which the Administrative Agent or the Banks have so become liable. Payments
hereunder by the Guarantors may be required by the Administrative Agent on any
number of occasions.

                                      -3-

ARTICLE 3.  WAIVERS.

         3.01 Guarantor's Waivers. Except to the extent expressly required by
any of the Loan Documents, each Guarantor waives, to the fullest extent
permitted by law, all of the following (including all defenses, counterclaims
and other rights of any nature based upon any of the following):

                  (a) presentment, demand for payment and protest of nonpayment
of any of the Obligations, and notice of protest, dishonor or nonperformance;

                  (b) notice of acceptance of this Guaranty and notice that
credit has been extended in reliance on such Guarantor's guaranty of the
Obligations;

                  (c) notice of any Default or Event of Default, of any
inability to enforce the Obligations or any provision of the Loan Documents, or
any rights against any Collateral;

                  (d) demand for performance or observance of, and any
enforcement of any provision of any of the Loan Documents, or any pursuit or
exhaustion of rights or remedies with respect to the Obligations or the
Collateral, and any requirement of diligence or promptness on the part of the
Administrative Agent in connection with any of the foregoing;

                  (e) any act or omission on the part of the Administrative
Agent which may impair or prejudice any rights of such Guarantor, including
rights to obtain subrogation, exoneration, contribution, indemnification or any
other reimbursement from any Obligor or other Person, or otherwise operate as a
deemed release or discharge;

                  (f) failure or delay to perfect or continue the perfection of
any security interest in any Collateral or any other action which harms or
impairs the value of, or any failure to preserve or protect the value of, any
Collateral;

                  (g) any statute of limitations or other rule of law which
provides that the obligation of a surety must be neither larger in amount nor in
other respects more burdensome than the obligation of the principal;

                  (h) any "single action" or "anti-deficiency" law which would
otherwise prevent the Administrative Agent from bringing any action, including
any claim for a deficiency, against such Guarantor before or after the
Administrative Agent's commencement or completion of any foreclosure action,
whether judicially, by exercise of power of sale or otherwise, or any other law
which would otherwise require any election of remedies by the Administrative
Agent;

                  (i) all demands and notices of every kind with respect to the
foregoing; and

                                      -4-
<PAGE>
                  (j) to the extent not referred to above, all defenses (other
than payment) which the Borrower may now or hereafter have to the payment of the
Obligations, together with all suretyship defenses, which could otherwise be
asserted by such Guarantor.

Each Guarantor represents that it has obtained the advice of legal counsel as to
the availability of suretyship and other defenses with respect to its
obligations hereunder in the absence of the waivers contained in this Section
3.01.

         3.02 Administrative Agent's Power to Waive, Etc. Each Guarantor grants
to the Administrative Agent full power in its sole discretion, without notice to
or consent of such Guarantor (such notice and consent being expressly waived to
the fullest extent permitted by applicable law), and without in any way
affecting the liability of such Guarantor hereunder:

                  (a) to waive compliance with, and any Default or Event of
Default under, and to consent to any amendment to or modification or termination
of any terms or provisions of, or to give any waiver in respect of, any of the
Loan Documents, the Collateral, the Obligations or any guaranty thereof (each as
from time to time in effect);

                  (b) to grant any extensions of the Obligations, and any other
indulgence with respect thereto, and to effect any total or partial release (by
operation of law or otherwise), discharge, compromise or settlement with respect
to the obligations of the Obligors or any other Person in respect of the
Obligations, whether or not rights against any Guarantor hereunder are reserved
in connection therewith;

                  (c) to take security in any form for the Obligations, and to
consent to the addition to or the substitution, exchange, release or other
disposition of, or to deal in any other manner with, any part of any property
contained in the Collateral whether or not the property, if any, received upon
the exercise of such power shall be of a character or value the same as or
different from the character or value of any property disposed of, and to
obtain, modify or release any present or future guaranties of the Obligations
and to proceed against any of the Collateral or such guaranties in any order;

                  (d) to collect or liquidate or realize upon any of the
Obligations or the Collateral in any manner or to refrain from taking any such
action; and

                  (e) to extend credit under any of the Loan Documents, or
otherwise, in such amount and on such terms as the Administrative Agent may
determine in its sole discretion, including increasing the amount of credit and
the interest rate and fees with respect thereto, even though the condition of
the Obligors (financial or otherwise, on an individual or Consolidated basis)
may have deteriorated since the date hereof.

         3.03 Non-Waiver by Administrative Agent. No delay or omission on the
part of the Administrative Agent in exercising any right under this Guaranty or
any other Loan Document, or under any guaranty of the Obligations, or with
respect to the Collateral,

                                      -5-
<PAGE>
shall operate as a waiver or relinquishment of such right. No action which the
Administrative Agent or the Borrower may take or refrain from taking with
respect to the Obligations or any Collateral, including the amendment or
modification of any document relating thereto, or any waiver with respect
thereto, shall affect the provisions of this Guaranty or the obligations of any
Guarantor hereunder. None of the Administrative Agent's rights shall at any time
in any way be prejudiced or impaired by any act or failure to act on the part of
any Obligor, or by any noncompliance by the Borrower with the terms, provisions
and covenants of any Loan Document, regardless of any knowledge thereof which
the Administrative Agent may have or with which the Administrative Agent may be
charged.

ARTICLE 4. INFORMATION REGARDING THE BORROWER, ETC. Each Guarantor (a) has made
such investigation as it deems desirable of the risks undertaken by it in
entering into this Guaranty and is fully satisfied that it understands all such
risks, (b) releases the Administrative Agent and the Banks from any obligation
which may now or hereafter exist to disclose to such Guarantor (i) the risks
being undertaken by entering into this Guaranty or of any changes in such risks
or (ii) any matter related to the business, operations, character, collateral,
credit, condition (financial or otherwise), income or prospects of the Borrower
or its Affiliates or their respective properties or management, whether now or
hereafter known by the Administrative Agent. Each Guarantor represents, warrants
and agrees that it has sole responsibility for obtaining from the Borrower all
information concerning the Loan Documents and all other information as to the
Borrower and its Affiliates or their respective properties or management as such
Guarantor deems necessary or desirable, and, from and after the date hereof,
each Guarantor undertakes to keep itself so informed.

ARTICLE 5. CERTAIN GUARANTOR REPRESENTATIONS. Each Guarantor represents, as to
itself, as of the date hereof that:

                  (a) it is in the best interest of such Guarantor, is
consistent with the purposes for which such Guarantor was organized as an
integral part of the business conducted and proposed to be conducted by the
Borrower Affiliated Group, and is reasonably necessary and convenient to the
conduct of such business, to induce the Administrative Agent and the Banks to
enter into the Loan Agreement and to extend credit to the Borrower by
undertaking the obligations set forth in this Guaranty;

                  (b) the business of such Guarantor benefits from the
successful performance of the business of each other Guarantor and each other
member of the Borrower Affiliated Group, and the Borrower Affiliated Group as a
whole; the failure of any member of the Borrower Affiliated Group to cooperate
with all other members of the Borrower Affiliated Group in the conduct of their
respective businesses is reasonably likely to have an adverse impact on the
business of each other member of the Borrower Affiliated Group; and the failure
of any member of the Borrower Affiliated Group to associate or cooperate with
all other members of the Borrower Affiliated Group is reasonably likely to
impair the goodwill of the Borrower Affiliated Group as a whole;

                                      -6-
<PAGE>
                  (c) the credit to be made available by the Banks under the
Loan Documents will directly or indirectly inure to such Guarantor's benefit;

                  (d) by virtue of the foregoing such Guarantor is receiving at
least reasonably equivalent value from the Administrative Agent and the Banks
for its guaranty hereunder;

                  (e) such Guarantor (i) has the ability to pay its debts from
time to time incurred in connection therewith as such debts mature, (ii) has,
and will have, access to adequate capital for the conduct of its business, and
(iii) will not be rendered Insolvent as a result of entering into this Guaranty;

                  (f) after giving effect to the transactions contemplated by
this Guaranty, such Guarantor will have assets having a fair saleable value in
excess of the amount required to pay its probable liability on its existing
debts as such debts become absolute and matured; and

                  (g) such Guarantor has been advised by the Administrative
Agent that the Administrative Agent and the Banks are unwilling to enter into
the Loan Agreement unless such Guarantor provides to the Administrative Agent
the guaranty contained herein.

ARTICLE 6. SUBROGATION. Each Guarantor agrees that, until the Obligations are
paid in full in cash, it will not exercise any right of reimbursement,
subrogation, contribution, offset or other claims against any Obligor arising by
contract or operation of law in connection with any payment made or required to
be made by such Guarantor under this Guaranty.

ARTICLE 7. SUBORDINATION. Each Guarantor covenants and agrees that, after the
occurrence and during the continuance of a Default or Event of Default, all
indebtedness, claims and liabilities then or thereafter owing by any Obligor to
such Guarantor whether arising hereunder or otherwise are subordinated to the
prior payment in full of the Obligations, and are so subordinated as a claim
against the Borrower or such Obligor, or any of its assets, whether such claim
be in the ordinary course of business or in the event of voluntary or
involuntary liquidation, dissolution, insolvency or bankruptcy, so that no
payment with respect to any such indebtedness, claim or liability will be made
or received while any Default or Event of Default exists.

ARTICLE 7A. LIMITATION ON GUARANTY OF OBLIGATIONS. In any action or proceeding
with respect to any Guarantor involving any state corporate law, or any state or
Federal bankruptcy, insolvency, reorganization or other law affecting the rights
of creditors generally, if the obligations of such Guarantor under Section 2.01
hereof would otherwise be held or determined to be void, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account
of the amount of its liability under said Section 2.01, then, notwithstanding
any other provision hereof to the contrary, the amount of such liability shall,
without any further action by such Guarantor, any Bank, the

                                      -7-
<PAGE>
Administrative Agent or any other Person, be automatically limited and reduced
to the highest amount which is valid and enforceable and not subordinated to the
claims of other creditors as determined in such action or proceeding.
