authorization of any other person or entity.

                  (d) The execution, delivery and performance of this Agreement,

encumbrance on any assets of the Borrower.

                  (e) This Agreement, the Note, and the other Loan Documents

law, regulation, order or agreement applicable to the Borrower or any of its
assets.

agrees that from the date hereof and until the later of the payment of all
Obligations or the termination of this Agreement, it will, unless the Lender

                  1.5 EVENTS OF DEFAULT. Upon the occurrence of any Event of
Default (as defined below), and at any time thereafter while such Event of
Default shall continue, the Lender may [in the case of any Event of Default
other than an event described in Sections 2.5(f) or (g) below] by written notice
to the Borrower:

                  (I) immediately terminate this Agreement; and/or

                  (II) immediately declare the principal of, and interest
accrued on, the Note forthwith due and payable, whereupon the same shall become
immediately due and payable, and/or provided, however, that upon the occurrence
of any event described in Sections 1.5 (f) or (g), the Lender hereunder shall
automatically and without notice terminate this Agreement, without any action on
the part of the Lender, and the principal of, and accrued interest on, the Note
and all other Obligations then outstanding, shall all become immediately due and
payable, both as to principal, interest and otherwise, without presentment,
demand, protest, or other notice of any kind, all of which are hereby expressly
waived, anything contained herein, or in the Note or any of the other Loan
Documents to the contrary notwithstanding. Upon the happening and continuance of
any Event of Default specified below, the Lender shall be permitted to proceed
to protect and enforce its rights under this Agreement and the other Loan
Documents, and each of them, and any of the other documents and instruments
executed and delivered in connection with this Agreement by such suits, actions
or special proceedings in equity or at law, or by proceedings in the office of
any board or officer having jurisdiction, either for specific performance of any
covenant or agreement contained herein or in aid or execution of any power
herein or therein granted or for the enforcement of any proper legal or
equitable remedy, as the Lender, being advised by counsel chosen by the Lender,
shall deem most effectual to protect and enforce such rights. In the enforcement
of any remedy described above, the Lender shall be entitled to sue for, enforce
payment of and receive any and all amounts then or during any Event of Default
becoming or remaining due from the Borrower for principal, interest or otherwise
under any of the provisions of this Agreement, the Note or any of the other Loan
Documents, as the case may be, together with interest on overdue payments at the
default rate as provided in the Note and all costs and expenses of collection
and of all proceedings hereunder. The rights and remedies provided hereunder are
cumulative, and are not exclusive of any other rights, powers, privileges, or
remedies, now or hereafter existing, at law or in equity or otherwise.
