     (a)  SUBSTANTIAL RELATIONSHIP. Lender is a national banking association.
Borrower is a Delaware limited liability company with its principal place of
business in Illinois. It is understood and agreed that all of the Loan Documents
have been negotiated, executed and delivered in the State of Illinois and the
payment of obligations of Borrower will be made from Illinois, which state the
parties agree has a substantial relationship to the parties and to the
underlying transactions embodied by the Loan Documents.

     (b)  GOVERNING LAW. Except as otherwise provided in this section, this Note
and each of the other Loan Documents shall in all respects be governed,
construed, applied and enforced in accordance with the laws of the state of
Illinois ("GOVERNING STATE"), without regard to the principles of conflicts of

     (c)  EXCEPTIONS. Notwithstanding the foregoing choice of law:

          (1)  The Mortgage and its validity, enforcement and interpretation
               shall be governed by the laws of the state where the Property is
               located (without regard to any conflict of law principles).

          (2)  The procedures governing the enforcement by Lender of its
               foreclosure and other remedies against the Borrower under the
               Mortgage and the other Loan Documents including, by way of
               illustration, but not limitation,

                                        3

               actions for foreclosure, for injunctive relief or for the
               appointment of a receiver shall be governed by the laws of the
               state where the Property is located.

          (3)  Lender shall comply with applicable law in the state where the
               Property is located to the extent required by the law of such
               jurisdiction in connection with the foreclosure of the security
               interests and liens created under the Mortgage and the other Loan
               Documents, with respect to the Property.

               Nothing contained herein or any other provisions of the Loan
               Documents shall be construed to provide that the substance of the
               laws of the state where the Property is located shall apply to
               any parties' rights and obligations under any of the Loan
               Documents, which, except as expressly provided in clauses (1),
               (2), and (3) of this section, are and shall continue to be
               governed by the substantive laws of the Governing State. In
               addition, the fact that portions of the Loan Documents may
               include provisions drafted to conform to the law of the state
               where the Property is located is not intended, nor shall it be
               deemed, in any way, to derogate the parties' choice of law as set
               forth or referred to in this Note or in the other Loan Documents.
               The parties further agree that the Lender may enforce its rights
               under the Loan Documents including, but not limited to, its
               rights to sue the Borrower or to collect any outstanding
               indebtedness in accordance with applicable law.
