                                                                    ------------

                                 PROMISSORY NOTE
                                 ---------------
                                  (SINGLE PAY)

$500,100                                                           June 17, 2005

     FOR VALUE RECEIVED, the undersigned (hereinafter "Maker"), hereby promises
to pay to the order of Robert B. Rosene, Jr., his successors, heirs, and
assigns, the principal sum of FIVE HUNDRED THOUSAND ONE HUNDRED DOLLARS AND
NO/100 ($500,100) with interest on the unpaid balance thereof from the date
hereof at the rate of Seven and One-Half percent (7.5%) per annum, with accrued
interest payable quarterly on a non-cash basis (Greystone equity or accrued at
Rosene's option) on the 1st day of each successive calendar month and the first
payment of interest due on or before March 31, 2006, and with principal plus all
accrued but unpaid interest due and payable as follows: one-third (1/3) January
2008; one-third (1/3) January 2009; and one-third (1/3) January 2010.

     If principal or any installment of interest, or any portion thereof, shall
not be paid when due, either according to the maturity dates above stated or by
acceleration under the terms hereof, then the same shall bear interest at the
rate of eighteen percent (18%) per annum until paid.

     The Maker hereof may prepay all or any portion of the principal hereof at
any time without prepayment penalty or premium. Any and all principal
prepayments permitted hereby must be accompanied by full payment of all interest
accrued on the amount of principal so prepaid.

     The Maker and any endorsers, sureties, guarantors and assignors of this
Note hereby severally waive demand, presentment for payment, notice of dishonor
or nonpayment, protest and notice of protest and any other notice, and agree and
consent that either before or after the maturity of this Note or any interest
installment hereof, the time for its payment or for the payment of any
installment may be extended from time to time by the holder hereof, without
notice and that after such extension or extensions each of them shall remain
bound for the payment hereof, notwithstanding such extension or extensions.

     Time is of the essence on this Note. If any installment of interest hereof
should not be paid when due, or if the Maker or any endorsers, sureties, or
guarantors should die, be dissolved, make an assignment for the benefit of
creditors, be adjudicated a bankrupt, or institute or have instituted against
them any insolvency or bankruptcy proceedings and any such involuntary
bankruptcy or involuntary insolvency proceedings are not dismissed within thirty
(30) days after commencement thereof, this Note shall become immediately due and
payable at the option of the holder, and notice of the election of this option
is expressly waived.

     If this Note or any portion of the principal or interest is not paid when
due, and is given to an attorney for collection, or suit is filed hereon, and as
often as any of such events occur, the Maker, and any endorsers, sureties and
guarantors, jointly and severally, agree to pay a reasonable attorney's fee and
court costs.
