execute, deliver and perform the terms and provisions of this Guaranty and has
taken all necessary action to authorize the execution, delivery and performance

   3

            (e) No Offsets. The undersigned has no offsets, defenses or
counterclaims to the enforcement of this Guaranty.

      4.      Other Provisions.

            (a) Continuing Guaranty. This is a continuing guaranty and shall
remain in full force and effect and be binding upon the undersigned, and the
undersigned's successors and assigns. Nothing except cash payment in full of all
Obligations shall release the undersigned from liability under this Guaranty.
This Guaranty is a guaranty of payment and not of collection, and neither the
Agent nor any Lender shall be under no obligation to take any action against
Borrower or any other person liable with respect to any of the Obligations or
resort to any collateral security held by it to secure any of the Obligations as
a condition precedent to the undersigned being obligated to perform as agreed
herein.

            (b) Acknowledgment. The undersigned hereby acknowledges that it has
derived or expects to derive a financial or other advantage from each and every
Obligation incurred by Borrower to the Lender.

            (c) Subrogation. Until such time as the Lender shall have received
payment in full in cash in satisfaction of all of the Obligations, the
undersigned waives any rights to be subrogated to the rights of the Lender with
respect to the Obligations and the undersigned waives any right to and agrees
that it will not institute or take any action against the Borrower seeking
contribution, reimbursement or indemnification by the Borrower with respect to
any payments made by the undersigned to the Lender hereunder.

            (d) Waivers. The undersigned waives notice of the acceptance of this
Guaranty and of the making of any such loans or extensions of credit,
presentment to or demand of payment from anyone whomsoever liable upon any of
the Obligations, protest, notice of presentment, non-payment or protest and
notice of any sale of collateral security or any default of any sort. The
undersigned hereby agrees that, in the event that any property of the
undersigned is or may be hypothecated with property of Borrower as security for
any Obligations, any right of the undersigned to have such property of Borrower
first applied to the discharge of such Obligations is hereby irrevocably waived
by the undersigned. The undersigned waives any and all notice of the creation,
renewal, extension or accrual of any of the Obligations or of the reliance by
Agent or the Lenders upon this Guaranty. The Obligations, and each of them,
shall conclusively be deemed to have been created, contracted or incurred in
reliance upon this Guaranty. This Guaranty shall be construed as a continuing,
absolute and unconditional guaranty without regard to 
   4

the validity, regularity or enforceability of the Obligations and any other
indebtedness at any time held or owing by the Agent and the Lenders to or for
the credit or the account of the undersigned against and on account of the
Obligations and liabilities of the undersigned hereunder. The undersigned hereby
waives any and all legal requirements that require or compel the Agent and the
Lenders to institute any action or proceedings at law or in equity against
Borrower, or anyone else, in respect of the Loans or any other document executed
in connection with the Loans or resort to or seek to realize upon or exhaust the
security held by the Agent or the Lenders or pursue any other remedy in the
Agent's or the Lenders' power, as a condition precedent to bringing an action
against the undersigned upon this Guaranty, and failure of the Agent or the
Lenders to do any of the foregoing shall not exonerate, release or discharge the
undersigned from its absolute, unconditional and independent liabilities to the
Agent and the Lenders hereunder. The undersigned hereby waives any rights to
interpose any defense (other than the defense of payment), counterclaim (other
than counterclaims which are required by law to be brought as part of the
proceedings brought by the holder hereof) or offset of any nature and
description which it may have or which may exist between and among the Agent,
any Lender, Borrower and/or the undersigned and any right to plead any election
of remedies.

            (e) Rights of the Agent and the Lenders. The Agent, on behalf of the
Lenders, may bring and prosecute a separate action against the undersigned to
enforce its liabilities hereunder, whether or not any action is brought against
Borrower or any other person and whether or not Borrower or any other person is
joined in any such action or actions. Nothing shall prohibit the Agent from
exercising its rights against the undersigned, the Borrower, the security, if
any, for the Obligations, and any other person simultaneously, jointly and/or
severally. The undersigned shall be bound by each and every ruling, order and
judgment obtained by the Agent against Borrower in respect of the Obligations,
whether or not the undersigned is a party to the action or proceeding in which
such ruling, order or judgment is issued or rendered.

            (f) No Discharge. The undersigned shall not be discharged, released
or exonerated, in any way, from its absolute, unconditional and independent
liabilities hereunder, even though any rights or defenses which the undersigned
may have against Borrower, the Lender or others may be destroyed, diminished or
otherwise affected by:

            (i)         Any declaration by the Agent or the Lenders of a default
                  in respect of any of the Obligations;

            (ii)        The exercise by the Agent or any Lender of any rights or
                  remedies against Borrower or any other person;
   5

            (iii)       The failure of the Agent or the Lenders to exercise any 
                  rights or remedies against Borrower or any other person;

            (iv)        The sale or enforcement of, or realization upon (through
                  judicial foreclosure, power of sale or any other means) any
                  security for any of the Obligations, even though (i) recourse
                  may not thereafter be had against Borrower for any deficiency,
                  or (ii) the failure of the Agent or any Lender to pursue any
                  such recourse which might otherwise be available; whether by
                  way of deficiency judgment following judicial foreclosure, or
                  otherwise;

            (v)         Any bankruptcy or reorganization of Borrower;

            (vi)        The release of any other guarantor by operation of law 
                  or otherwise; or

            (vii)       The voluntary or involuntary participation by Borrower 
                  in any settlement or composition for the benefit of Borrower's
                  creditors either in liquidation, readjustment, receivership,
                  bankruptcy or otherwise.

            (g) Unconditional Nature of Guaranty. This Guaranty is absolute and
unconditional and shall not be changed or affected by any representation, oral
agreement, act or thing whatsoever, except as herein otherwise expressly
provided. No modification or amendment of any provisions of this Guaranty shall
be effective unless in writing and signed by a duly authorized officer of the
Agent.

            (h) Preservation of Rights. No failure on the part of the Agent or
any Lender to exercise, and no delay in exercising, any right, remedy or power
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise by the Agent or the Lenders of any right, remedy or power hereunder
preclude any other or future exercise of any other right, remedy or power. Each
and every right, remedy and power hereby granted to the Agent and the Lenders or
allowed it by law or other agreement shall be cumulative and not exclusive of
any other, and may be exercised by the Agent and Lenders at any time and from
time to time.
