                                OF THE GUARANTOR


The Guarantor does hereby represent and warrant to the Holder that:

SECTION 1.1. AUTHORITY OF THE GUARANTOR. The Guarantor represents and warrants
that it is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware, possesses full corporate power
and corporate capacity to consummate the transactions contemplated hereby and is
authorized to conduct business in all jurisdictions wherein the nature of its
activities requires such except where the failure to do so would not have a
material adverse effect upon the Guarantor.

SECTION 1.2. NO VIOLATION OF RESTRICTIONS. The Guaranty and all other documents
to be executed by the Guarantor in connection therewith, when executed and
delivered by the respective parties thereto, will constitute valid and binding
obligations of the Guarantor. The execution and delivery by the Guarantor of the
Financing Documents to which it is a party and the performance thereof by the
Guarantor (1) have been authorized by all necessary corporate action and (2) do
not and will not conflict with, or result in any breach of, or constitute a
default under the Guarantor's articles of incorporation or by-laws or any
indenture, mortgage, deed of trust, bank loan or credit agreement or any other
agreement or instrument to which the Guarantor is a party or by which the
Guarantor or any of its Property may be bound for which a valid consent has not
been secured except where the failure to do so would not have a material adverse
effect upon the Guarantor, or result in the creation of any Lien (other than
that created by the Financing Documents) upon or with respect to any Property of
the Guarantor.

SECTION  1.3.   GOVERNMENTAL  CONSENT.  No  approval  or  other  action  by  any
Governmental   Authority  is  required  in  connection  with  the  execution  or
performance by the Guarantor of the Guaranty.

SECTION 1.4. PENDING LITIGATION. As of the date hereof, there are no actions,
suits or proceedings at law or in equity, or before or by any Governmental
Authority, pending or, to the knowledge of the Guarantor, threatened against or
affecting the Guarantor which are reasonably likely to materially adversely
affect the financial condition of the Guarantor and of the Company taken as a
whole or involving the validity or enforceability of the Financing Documents to
which it is a party or the priority of the Liens thereof, and to the Guarantor's
knowledge it is not in default with respect to any material order, writ,
judgment, decree or demand of any court or any Governmental Authority.

SECTION 1.5. NO DEFAULTS. No event has occurred and no condition exists which,
upon the execution of this Guaranty, would constitute an Event of Default under
Article III hereof.

SECTION 1.6. TAXES. All material Federal, state, county, municipal and city
income and other tax returns and other reports and documents required to have
been filed by the Guarantor have been filed and the Guarantor has paid all fees
and taxes indicated as due pursuant to such returns, reports and documents or
pursuant to any assessments received by the Guarantor, and the Guarantor knows
of no basis for any additional material assessment in respect of any such taxes
which has not been or will not be reserved for in accordance with GAAP.

reserved to the Holder is intended to be exclusive of any other available remedy
or remedies, but each and every such remedy shall be cumulative and shall be in
addition to every other remedy given under this Guaranty or now or hereafter
existing at law or in equity or by statute.

     (B) No delay or omission to exercise any right or power accruing upon the

arising, upon and against all deposits, credits, collateral and property, now or
hereafter in the possession, custody, safekeeping or control of the Holder or
any entity under the control of FleetBoston Financial Corporation and its

occurrence and during the continuance of an Event of Default, without demand or
notice (any such notice being expressly waived by the Guarantor), the Holder may
set off the same or any part thereof and apply the same to any liability or
obligation of the Guarantor even though unmatured and regardless of the adequacy

WHICH SECURES THE NOTES, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO
SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE GUARANTOR, ARE HEREBY KNOWINGLY,
VOLUNTARILY AND IRREVOCABLY WAIVED.

terms, or in connection with the Holder's exercise, preservation or enforcement
of any of its rights, remedies or options hereunder, including, without
limitation, reasonable fees of outside legal counsel or the allocated costs of
in-house legal counsel, accounting, consulting, brokerage or other similar

connection with the loan or any collateral therefor, and the amount of all such
expenses shall, until paid, bear interest at the rate applicable to principal
hereunder (including any default rate) and be an obligation secured by any
collateral.
