This Note is the Revolving Promissory Note described in the Loan
Agreement, to which reference is hereby made for a more complete statement of
the terms and conditions under which the Advances and Credit Extensions
evidenced hereby are made. The indebtedness evidenced by this Note amends and
restates in its entirety that certain Revolving Promissory Note dated as of
January 14, 2003 (the Prior Note) in the maximum principal amount of Twenty
Million Dollars ($20,000,000) from the Borrower in favor of the Bank, as
amended prior to the date hereof. It is expressly agreed that the indebtedness
evidenced by the Prior Note has not been extinguished or discharged hereby.
The Borrower agrees that the execution of and delivery of this Note is not
intended to and shall not cause or result in a novation with respect to the
Prior Note. This Note may be secured as provided in the Loan Agreement. All
capitalized terms used herein and not otherwise defined shall have the meanings
given to such terms in the Loan Agreement. Each Borrower irrevocably waives the right to direct the application of
any and all payments at any time hereafter received by Bank from or on behalf
of any Borrower and each Borrower irrevocably agrees that Bank shall have the
continuing exclusive right to apply any and all such payments against the then
due and owing obligations of either Borrower as Bank may deem advisable. In
the absence of a specific determination by Bank with respect thereto, all
payments shall be applied in the following order: (a) then due and payable fees
and expenses; (b) then due and payable interest payments and mandatory
prepayments; and (c) then due and payable principal payments and optional
prepayments. Bank is hereby authorized by each Borrower to endorse on Banks books and
records each Advance made by Bank under this Note and the amount of each
payment or prepayment of principal of each such Advance received by Bank; it
being understood, however, that failure to make any such endorsement (or any
error in notation) shall not affect the joint and several obligations of each
Borrower with respect to Advances made hereunder, and payments of principal by
any Borrower shall be credited to Borrowers notwithstanding the failure to make
a notation (or any errors in notation) thereof on such books and records. The occurrence of any one or more of the following events shall constitute
an event of default (individually, an Event of Default and collectively, the
Events of Default) under the terms of this Note: (a) The failure of either Borrower to pay to Bank within three (3)
Business Days of when due any and all amounts payable by either Borrower to
Bank under the terms of this Note; or (b) The occurrence of an Event of Default (as defined therein) under the
terms and conditions of any of the other Loan Documents. Upon the occurrence of an Event of Default, at the option of Bank, all
amounts payable by either Borrower to Bank under the terms of this Note shall
immediately become due and payable by Borrowers to Bank without notice to any
Borrower or any other Person, and Bank shall have all of the rights, powers,
and remedies available under the terms of this Note, any of 2

the other Loan Documents and all applicable laws. Each Borrower and all
endorsers, guarantors, and other parties who may now or in the future be
primarily or secondarily liable for the payment of the indebtedness evidenced
by this Note hereby severally waive presentment, protest and demand, notice of
protest, notice of demand and of dishonor and non-payment of this Note and
expressly agree that this Note or any payment hereunder may be extended from
time to time without in any way affecting the joint and several liability of
Borrowers, guarantors and endorsers. Until such time as Bank is not committed to extend further credit to the
Borrowers and all Obligations of the Borrowers to Bank have been indefeasibly
paid in full in cash, and subject to and not in limitation of the provisions
set forth in the next following paragraph below, no Borrower shall have any
right of subrogation (whether contractual, arising under the bankruptcy code or
otherwise), reimbursement or contribution from any Borrower or any guarantor,
nor any right of recourse to its security for any of the debts and obligations
of any Borrower which are the subject of this Note. Except as otherwise
expressly permitted by the Loan Agreement, any and all present and future debts
and obligations of any Borrower to any other Borrower are hereby subordinated
to the full payment and performance of all present and future debts and
obligations to Bank under this Note and the Loan Agreement and the Loan
Documents, provided, however, notwithstanding anything set forth in this Note
to the contrary, prior to the occurrence of a payment default, the Borrowers
shall be permitted to make payments on account of any of such present and
future debts and obligations from time to time in accordance with the terms
thereof. Each Borrower further agrees that, if any payment made by any Borrower or
any other person is applied to this Note and is at any time annulled, set
aside, rescinded, invalidated, declared to be fraudulent or preferential or
otherwise required to be refunded or repaid, or the proceeds of any property
hereafter securing this Note is required to be returned by Bank to any
Borrower, its estate, trustee, receiver or any other party, including, without
limitation, such Borrower, under any bankruptcy law, state or federal law,
common law or equitable cause, then, to the extent of such payment or
repayment, such Borrowers liability hereunder (and any lien, security interest
or other collateral securing such liability) shall be and remain in full force
and effect, as fully as if such payment had never been made, or, if prior
thereto any such lien, security interest or other collateral hereafter securing
such Borrowers liability hereunder shall have been released or terminated by
virtue of such cancellation or surrender, this Note (and such lien, security
interest or other collateral) shall be reinstated in full force and effect, and
such prior cancellation or surrender shall not diminish, release, discharge,
impair or otherwise affect the obligations of such Borrower in respect of the
amount of such payment (or any lien, security interest or other collateral
securing such obligation). The JOINT AND SEVERAL obligations of each Borrower under this Note shall
be absolute, irrevocable and unconditional and shall remain in full force and
effect until the outstanding principal of and interest on this Note and all
other Obligations or amounts due hereunder and under the Loan Agreement and the
Loan Documents shall have been indefeasibly paid in full in cash in accordance
with the terms thereof and this Note shall have been canceled. 3

and all other notices and demands in connection with the delivery, acceptance,
performance default or enforcement of this Note, as well as any applicable
statutes of limitations. No delay by Bank in exercising any power or right
hereunder shall operate as a waiver of any power or right. Time is of the
essence as to all obligations hereunder. This Note is issued pursuant to the Loan Agreement, which shall govern the
rights and obligations of Borrowers with respect to all obligations hereunder. Each Borrower acknowledges and agrees that this Note shall be governed by
