            REPRESENTATIONS AND WARRANTIES OF THE CORPORATE GUARANTOR

     SECTION 1.1 Corporate Guarantor's Representations and Warranties. The
Corporate Guarantor does hereby represent and warrant as follows:

     (a) Power. The Corporate Guarantor is a corporation duly incorporated in
         -----
the State of Delaware and in good standing in the State of New York, has power
to enter into and perform this Guaranty Agreement and to own its corporate
property and assets, has duly authorized the execution and delivery of this
Guaranty Agreement by proper corporate action and neither this Guaranty
Agreement, the authorization, execution, delivery and performance hereof, the
performance of the agreements herein contained nor the consummation of the
transactions herein contemplated will violate or be in conflict with or result
in a breach or constitute (with due notice and/or lapse of time) a default under
any provision of law, any order of any court or agency of government or any
agreement, indenture or other instrument to which such Corporate Guarantor is a
party or by which it or its property is bound, or any provision of its
certificates of incorporation, by-laws, or any other requirement of law. This
Guaranty Agreement constitutes the legal, valid and binding obligation of the
Corporate Guarantor enforceable against the Corporate Guarantor in accordance
with its terms, except to the extent that such enforceability may be limited by
bankruptcy or insolvency or other laws affecting creditor's rights generally or
by general principles of equity.

     (b) Benefit. The assumption by the Corporate Guarantor of its obligations
         -------
hereunder will result in a direct financial benefit to such Corporate Guarantor
and its shareholders.

     SECTION 1.2 Reserved.

                                       -3-

<PAGE>

                                   ARTICLE 2.

                             AGREEMENT TO GUARANTEE

     SECTION 2.1 Obligations Guaranteed. (a) The Corporate Guarantor hereby
                 ----------------------
irrevocably, absolutely and unconditionally guarantees to the Trustee for the
benefit of the Holders from time to time of the Bonds, the Bank and the Issuing
Agent (1) the full and prompt payment of the principal of the Bonds and the
indebtedness represented thereby, and the redemption premium, if any, on the
Bonds when and as the same shall become due and payable, whether at the stated
maturity thereof, by acceleration, call for redemption, purchase or otherwise,
(2) the full and prompt payment of interest on the Bonds when and as the same
shall become due and payable and, if the Letter of Credit is in effect, on any
amounts due and owing to the Bank, (3) the payment, performance and observance
of all obligations of the Lessee in favor of the Bank and the Issuing Agent
under the Reimbursement Agreement and in respect of the Letter of Credit, (4) to
the extent permitted by law, the full and prompt payment of an amount equal to
each and all of the rental payments and other sums, when and as the same shall
become due, required to be paid by the Lessee under the terms of the Lease
Agreement, and (5) to the extent permitted by law, the full and prompt
performance and observance by the Lessee of all of the obligations, covenants
and agreements required to be performed and observed by the Lessee under the
terms of the Lease Agreement (the payments, obligations, covenants and
agreements referred to above being collectively referred to as the "Guaranteed
Obligations"). The Corporate Guarantor further hereby irrevocably, absolutely
and unconditionally agrees that upon any default in the payment of any the
Guaranteed Obligations, the Corporate Guarantor will promptly pay the same. All
payments by the Corporate Guarantor shall be paid in lawful money of the United
States of America. Each and every default in the payment of any of the
Guaranteed Obligations shall give rise to a separate cause of action hereunder,
and separate suits may be brought hereunder as each cause of action arises.

     (b) The Corporate Guarantor agrees that this Guaranty Agreement constitutes
an absolute, unconditional, present and continuing guarantee of payment and not
of collection, and waives any right to require that any resort be had by the
Trustee, the Holders of the Bonds, the Bank or the Issuing Agent to (1) any
security held by or for the benefit of the Holders of the Bonds, the Bank or the
Issuing Agent for any of the Guaranteed Obligations, (2) the Trustee's, any
Bondholder's, the Bank's or the Issuing Agent's rights against any other person,
or (3) any other right or remedy available to the Trustee, any Holder of the
Bonds, the Bank or the Issuing Agent by contract, applicable law or otherwise.
The obligations of the Corporate Guarantor under this Guaranty Agreement are
direct, unconditional and completely independent of the obligations of any other
Person, and a separate cause of action or separate causes of action may be
brought and prosecuted against the Corporate Guarantor without the necessity of
joining the Agency or any other party or previously proceeding with or
exhausting any other remedy against any other Person who might have become
liable for any of the Guaranteed Obligations or of realizing upon any security
held by or for the benefit of the Holders of the Bonds, the Bank or the Issuing
Agent.

     (c) Reference is made to Article X of the Indenture which provides that,
subject to certain conditions, the Indenture may be discharged prior to the date
on which all of the Bonds have become due and payable if there shall be
deposited with the Trustee moneys and/or

                                       -4-

<PAGE>

Government Obligations in an amount sufficient to pay the entire principal of,
redemption premium, if any, and interest due and to become due on such Bonds on
or prior to the maturity or redemption thereof. If any lien, encumbrance or
charge based on any claim of any kind (including, without limitation, any claim
for income, franchise or other taxes, whether Federal, state or otherwise but
excluding any claim against any Bondholder) shall be asserted or filed against
any moneys so deposited with the Trustee (or the income therefrom) so as to:

         (1)     interfere with the due application by the Trustee of such
     moneys to the payment of the Bonds or the reimbursement of the Bank or the
     Issuing Agent for draws under the Letter of Credit, pursuant to the
     applicable provisions of the Indenture, or

         (2)     subject the Holders of the Bonds, the Bank or the Issuing Agent
     to any obligation to refund any moneys applied to payment of the Bonds or
     the reimbursement of amounts drawn under the Letter of Credit,

then the Corporate Guarantor promptly will take, or cause the taking of, such
action (including, but not limited to, the payment of money) as may be necessary
to prevent, or to nullify the cause or result of, such interference or such
obligation, as the case may be.

     The discharge of the lien and pledge of the Indenture prior to the date on
which all Bonds have become due and payable shall not release the Corporate
Guarantor from its obligations under this Guaranty Agreement except to the
extent the Bonds are defeased pursuant to Article X of the Indenture.

     The Corporate Guarantor further waives any benefits of any credit for the
fair market value of the Facility in any action for foreclosure or for a
deficiency judgment (including any credit under Section 1371 of the New York
Real Property Actions and Proceedings Law).

     SECTION 2.2 Obligations Unconditional. The obligations of the Corporate
                 -------------------------
Guarantor under this Guaranty Agreement shall be absolute and unconditional, and
shall remain in full force and effect until the Guaranteed Obligations shall
have been paid in full or provided for, and all costs, Trustee's fees and
commissions and expenses, if any, referred to in Section 2.5 hereof shall have
been paid in full, and, to the extent permitted by law, such obligations shall

of the close of the preceding fiscal year and at all times during such fiscal
year, the Corporate Guarantor was in compliance with all of the provisions in
each Security Document to which it is a party, and if such Authorized
Representative shall have obtained knowledge of any default in such compliance
or notice of such default, the Authorized Representative of the Corporate
Guarantor shall disclose in such certificate such default or defaults or notice
thereof and the nature thereof, whether or not the same shall constitute an
Event of Default hereunder, and any action proposed to be taken by the Corporate
Guarantor with respect thereto. In addition, upon twenty (20) days' prior
request (such request not to be made more frequently than semi-annually) by the
Agency, the Trustee, the Bank or the Issuing Agent, the Corporate Guarantor will
execute, acknowledge and deliver to the Agency, the Trustee, the Bank or the
Issuing Agent a certificate of an Authorized Representative of the Corporate
Guarantor either stating that to his knowledge no default or breach exists
hereunder or specifying each such default or breach of which he has knowledge.

     (b) The Corporate Guarantor covenants and agrees that so long as any
Guaranteed Obligations remain outstanding, the Corporate Guarantor will,
promptly after obtaining knowledge thereof, notify the Trustee, the Bank, the
Issuing Agent and the Agency in writing of the occurrence of any default under
any of the Security Documents and the occurrence of any event which, with the
giving of notice, could become an Event of Default of which the Corporate
Guarantor has knowledge. Any notice required to be given pursuant to this
Section shall be signed by an Authorized Representative of the Corporate
Guarantor and set forth a description of the default and the steps, if any,
being taken to cure said default. If no steps have been taken, this fact must be
plainly stated.

     SECTION 2.9 Benefit and Enforcement. This Guaranty Agreement is entered
                 -----------------------
into by the Corporate Guarantor for the benefit of the Trustee, the Agency, the
Holders from time to time of the Bonds, the Bank and the Issuing Agent, all of
whom shall be entitled in the same

manner as set forth in the Indenture to enforce performance and observance of
this Guaranty Agreement to the same extent as if all were parties signatory
hereto.

     SECTION 2.10 Survival of Guarantee Obligation. If the Trustee, the Bank or
                  --------------------------------
the Issuing Agent receives any payment on account of the Guaranteed Obligations,
which payment or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be transferred or
repaid to a trustee, receiver, assignee for the benefit of creditors or any
other party under any bankruptcy act or code, state or federal law or common law
or equitable doctrine or for any other reason whatsoever, then to the extent of
any sum not finally retained by the Trustee, the Bank or the Issuing Agent, this
Guaranty Agreement shall remain in full force and effect until the Corporate
Guarantor shall have indefeasibly made payment to the Trustee, the Bank or the
Issuing Agent, as the case may be, of such sum, which payment shall be due on
demand. If the Trustee, the Bank or the Issuing Agent chooses to contest any
such matter, the Corporate Guarantor agrees to indemnify and hold harmless the
Trustee, the Bank or the Issuing Agent, as the case may be, with respect to all
costs (including court costs and reasonable attorneys' fees) of such litigation.

     SECTION 2.11 Waiver of Rights of Trustee, Bank and the Issuing Agent. No
                  -------------------------------------------------------
payment hereunder by the Corporate Guarantor shall entitle the Corporate
Guarantor by subrogation to the rights of the Trustee, the Bank or the Issuing
Agent to any payment by any other obligor or out of the property of any other
obligor, except after payment and performance in full of the Guaranteed
Obligations, at which time the Corporate Guarantor shall succeed to all of the
rights and security held by the Bank and the Trustee. Until so subrogated, the
Corporate Guarantor waives any benefit of, or any right to participation in, any
security whatsoever now or hereafter held by or for the benefit of the Trustee,
the Bank or the Issuing Agent.
