     FOR VALUE RECEIVED, the undersigned (hereinafter, together with their
successors in title and assigns, collectively, called the "Borrowers"), by this
promissory note (hereinafter, together with the Schedule annexed hereto, called
"this Note"), absolutely and unconditionally and jointly and severally promise
to pay to the order of ____________ (hereinafter, together with its successors
in title and assigns, called the "Bank"), the principal sum of _____________
___________________________, or so much thereof as shall have been advanced by
the Bank to the Borrowers by way of revolving credit loans under the Loan
Agreement (as hereinafter defined) and shall remain outstanding, such payment to
be made as hereinafter provided, and to pay interest on the principal sum
outstanding hereunder from time to time from the date hereof until the said
principal sum or the unpaid portion thereof shall have become due and payable as
hereinafter provided.

     Capitalized terms used herein without definition shall have the meaning set
forth in the Loan Agreement.

     The unpaid principal (not at the time overdue) under this Note shall bear
interest at the rate or rates from time to time in effect under the Loan
Agreement. Accrued interest on the unpaid principal under this Note shall be
payable on the dates specified in the Loan Agreement.

     On December 31, 2006, the date of the final maturity of this Note, there
shall become absolutely due and payable by the Borrowers hereunder, and the
Borrowers hereby jointly and severally promise to pay to the Bank, the balance
(if any) of the principal hereof then remaining unpaid, all of the unpaid
interest accrued hereon and all (if any) other amounts payable on or in respect
of this Note or the indebtedness evidenced hereby.

     Each overdue amount (whether of principal, interest or otherwise) payable
on or in respect of this Note or the indebtedness evidenced hereby shall (to the
extent permitted by applicable law) bear interest at the rates and on the terms
provided by the Loan Agreement. The unpaid interest accrued on each overdue
amount in accordance with the foregoing terms of this paragraph shall become and
be absolutely and jointly and severally due and payable by the Borrowers to the
Bank on demand by the Administrative Agent. Interest on each overdue amount will
continue to accrue as provided by the foregoing terms of this paragraph, and
will (to the extent permitted by applicable law) be compounded daily until the
obligations of the Borrowers in respect of the payment of such overdue amount
shall be discharged (whether before or after judgment).

     Each payment of principal, interest or other sum payable on or in respect
of this Note or the indebtedness evidenced hereby shall be made by the Borrowers
directly to the Administrative Agent in dollars, for the account of the Bank, at
the address of the Administrative Agent set forth in the Loan Agreement, on the
due date of such payment, and in immediately available and

indebtedness evidenced hereby shall be made without set-off or counterclaim and
free and clear of and without any deductions, withholdings, restrictions or
conditions of any nature.

     This Note is made and delivered by the Borrowers to the Bank pursuant to
the Revolving Credit and Term Loan Agreement, dated as of June 24, 2003, among
(i) the Borrowers, (ii) the Banks and (iii) the Administrative Agent
(hereinafter, as originally executed, and as now or hereafter varied or
supplemented or amended and restated, called the "Loan Agreement"), to which
reference is hereby made for a statement of the terms and conditions (to the
extent not set forth herein) under which the Loans evidenced by this Note were
made and are to be repaid. This Note evidences the joint and several obligation
of the Borrowers (a) to repay the principal amount of the Bank's Commitment

provided, on the principal amount hereof remaining unpaid from time to time; and
(c) to pay other amounts which may become due and payable hereunder or
thereunder as herein and therein provided. The payment of the principal of and
the interest on this Note and the payment of all (if any) other amounts as may
become due and payable on or in respect of this Note are secured by certain
collateral, as evidenced by the Security Documents. Reference is hereby made to
the Loan Agreement (including the EXHIBITS and SCHEDULES annexed thereto) and to

Agreement, the entire unpaid principal of this Note, all of the interest accrued
on the unpaid principal of this Note and all (if any) other amounts payable on
or in respect of this Note or the indebtedness evidenced hereby may be declared

Note, all of the interest accrued on the unpaid principal of this Note and all
(if any) other amounts payable on or in respect of this Note or the indebtedness
evidenced hereby shall (if not already due and payable) forthwith become and be
due and payable to the Bank without presentment, demand, protest or any other
formalities of any kind, all of which are hereby expressly and irrevocably
waived by the Borrowers, excepting only for notice expressly provided for in the
Loan Agreement.

     All computations of interest payable as provided in this Note shall be made
by the Administrative Agent in accordance with the terms of the Loan Agreement.

reasonably incurred or sustained by the holder of this Note.

     No delay or omission on the part of the Bank or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Bank or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any further occasion.

irrevocably waives notice of acceptance, presentment, demand, notice of
nonpayment, protest, notice of protest, suit and all other demands, notices and
