      Loan$3,900,000.00
            Funding
      Date: January 11, 2007




FOR VALUE RECEIVED, DPMG, INC., ("Maker"),
promises to pay to the order of Key Equipment Finance Inc.,
("Holder"), the sum of $3,900,000.00 in
lawful money of the United States of America (the "Principal"), with interest
thereon as hereafter provided ("Interest"), to be paid in the manner set forth
herein.  This Note is executed pursuant to and is secured by, the
Collateral pledged under that certain aircraft security agreement (the "Aircraft
Security Agreement") dated as of January 11, 2007 between Maker as grantor and
Holder as secured party. Capitalized terms used herein without definition shall
have the meaning given them in the Aircraft Security Agreement.




1.           Interest
Rate; Closing Rate Adjustment; Place of Payment.  (a) Interest
on the balance of the Principal outstanding on this Note shall accrue from the
Funding Date of this Note and shall be due and payable at a rate of 6.83% per
annum (the "Interest Rate") which rate shall be immediately and correspondingly
adjusted (pursuant to 2(b) hereof) with each change in the Actual Index (as
hereinafter defined).  Interest shall be calculated on the basis of a
360-day year consisting of twelve 30-day months.




(b) The
Interest Rate has been calculated on the assumption that the LIBOR Rate as
reported in the Wall Street Journal on the Funding Date (the “Assumed LIBOR
Rate”) will be 5.32%. If the LIBOR rate on the Funding Date is different from
the Assumed LIBOR Rate, Holder shall make a one time adjustment to the Interest
Rate on the Funding Date by increasing or decreasing, as applicable, the
Interest Rate by one (1) basis point for every one (1) basis point change in the
LIBOR Rate from the Assumed LIBOR Rate. Maker authorizes Holder to change the
amount of the Interest Rate in the Note accordingly. Holder shall notify Maker
in writing of such adjustment which shall remain in effect while any
indebtedness exists under the Note.




(c) Payment
of the Principal and Interest hereunder shall be made to Holder at 66 South
Pearl Street, Post Office Box 1865, Albany, NY 12201-1865, or at such other
place as Holder may designate from time to time in writing. Holder reserves the
right to require payment on this Note to be made by wired federal funds or other
immediately available funds.




2.           Repayment
Terms.  (a) Maker shall
repay the Principal and Interest hereunder in the installments set forth
below.  Each installment shall be due and payable on the first day of
each month during which any amount remains outstanding hereunder (each such date
being a "Note Payment Date") as follows:




(i) If
the Funding Date occurs on the first day of the month, Maker shall pay Holder 84
consecutive Monthly installments payable in arrears, each in an amount equal to
$34,916.63 commencing and payable on the next Note Payment Date after the
Funding Date and on each succeeding Note Payment Date thereafter;




OR




(ii) If
the Funding Date occurs on any day other than the first day of the month, then
(A) on the first Note Payment Date after the Funding Date, an amount equal to
$739.92 per day as interim interest for the period from the Funding Date through
and including the last day of the month in which the Funding Date occurs, which
interim interest was calculated by Holder using the Assumed Index plus 151 basis
points and is expressly not subject to adjustment pursuant to Section 2(b)
hereof; plus (B) 84 consecutive Monthly installments payable in arrears, each in
an amount equal to $34,916.63 commencing and payable on the second Note Payment
Date following the Funding Date and on each succeeding Note Payment Date
thereafter;




PLUS




(iii) On
the 84 and finalNotePayment Date, the
Balloon Payment. In addition, Maker will pay a late payment charge of five
percent of any payment due hereunder that is not paid on or before ten (10) days
after the date due hereunder.

(b) Maker
and Holder agree that each monthly installment hereunder will be increased or
decreased (but not below zero), as the case may be, by the Rate Differential as
follows: if, as of any Note Payment Date, (i) the Rate Differential is
greater than zero, the amount due on such Note Payment Date shall be increased
by such Rate Differential, and (ii) if the Rate Differential is less than zero,
the amount of the Note Payment due on such Note Payment Date shall be decreased
by such Rate Differential.


(c) As
used herein, the following terms have the respective meanings indicated
below:




(i)
“Assumed Index”
means 5.32%

      Index x Net Investment Balance
                12




3.           Security.
Payment of the Principal and Interest hereunder, and the performance and
observance by Maker of all agreements, covenants and provisions contained
herein, is secured by a first priority security interest in the
Collateral.




4.           Prepayment.
Except as contemplated by Section 3.1 of Article 3 of the Aircraft Security
Agreement, Maker may not prepay, in whole or in part, the Principal outstanding
hereunder; provided,
however, Maker may prepay, on any Note Payment Date and in whole but not
in part, the Principal outstanding hereunder including the Balloon Payment by
paying to Holder such outstanding Principal, together with all accrued and
unpaid interest thereon as of the date of payment, plus all fees or charges
incurred by Holder in connection with such prepayment, including, without
limitation, Holder’s reasonable attorney fees and expenses, FAA counsel fees and
expenses,  filing, registration and recording fees or charges of the
FAA, International Registry and the UCC and any applicable taxes (but excluding
internal costs to Holder related to such prepayment), plus a prepayment premium
("Prepayment Premium") equal to a percentage of the outstanding Principal
including the Balloon Payment calculated as follows:

Notwithstanding
anything to the contrary contained herein or in the Aircraft Security Agreement,
Holder will waive its right to require payment of the Prepayment Premium if (a)
Maker wishes to prepay the outstanding principal hereunder in connection with
Maker’s acquisition of a new aircraft, and (i) Maker wishes to finance the
purchase of such new aircraft through Holder, and (ii) Holder in its sole
discretion determines that it approves of the then credit-worthiness of Maker,
the new aircraft, and all aspects of the financing of the new aircraft, and
(iii) Maker enters into a new promissory note and aircraft security agreement
for the benefit of and on terms satisfactory to Holder to finance such new
aircraft; or (b) after the twelfth (12th) Note
Payment Date, Maker exercises the option to make no more than one (1) annual
additional principal reduction payment without penalty, provided that such
payment shall be equal to or greater than five percent (5%) of the original
Principal balance of this Note and the cumulative amount of all such prepayments
under this Section 4 (b) during the term hereof, shall not exceed twenty-five
percent (25%) of the original Principal balance of this Note.

5.           Transfer
or Assignment.  Holder may at any time assign or otherwise
transfer or negotiate this Note in whole or in part, without any notice to
Maker.  The rights and obligations of Maker may not be assigned or
delegated.
  6.           Application
of Payments.  Prior to an Event of Default, each payment
received on this Note shall be applied first to all costs of collection, then to
unpaid late payment charges (if any) and Prepayment Premium (if any) hereunder,
then to Interest as of the payment due date and the balance, if any, to the
outstanding Principal as of the date received.  Upon the occurrence,
and during the continuance, of an Event of Default, any payments in respect of
the Liabilities and any proceeds of the Collateral when received by Holder in
cash or its equivalent, will be applied first to costs of collection and,
thereafter, in reduction of the Liabilities in such order and manner as Holder
may direct in its sole discretion, and Maker irrevocably waives the right to
direct the application of such payments and proceeds and acknowledges and agrees
that Holder shall have the continuing and exclusive right to apply any and all
such payments and proceeds in the Holder's sole discretion, notwithstanding any
entry to the contrary upon any of its books and records.





7.           Events of
Default.  (a) Maker shall be in default if any of the following
happens  (an "Event of Default"): (1) Maker fails to make any
installment of the Principal or Interest, or any other payment due and owing,
under this Note within ten (10) days after the same becomes due and payable; or
(2) Maker fails to perform any other obligation required to be performed by
Maker under this Note, the Aircraft Security Agreement or any of the other Loan
Documents for thirty (30) days after written notice from Holder of such failure;
or (3) any representation, warranty or other statement by or on behalf of Maker
in connection with this  Note is false or misleading in any material
respect; or (4) an Event of Default has occurred and is continuing under the
Aircraft Security Agreement.


(b)
Notwithstanding anything to the contrary contained herein, upon the occurrence
of an Event of Default, Holder may declare the entire outstanding balance of the
Principal, together with all accrued and unpaid Interest thereon, immediately
due and payable without notice or demand which amounts shall, together with all
other sums due hereunder, accrue interest from such acceleration until the date
of actual payment at the Default Rate ("Default Rate" shall mean an annual
interest rate equal to the lesser of 18% or the maximum interest rate permitted
by Applicable Law).  Should there occur an Event of Default, and if a
voluntary or involuntary petition under the United States Bankruptcy Code is
filed by or against Maker while such default remains uncured, the entire
outstanding balance of the Principal automatically shall be accelerated and due
and payable with interest thereon at the Default Rate and Holder may exercise
any and all of its remedies hereunder, under the other Loan Documents and under
Applicable Law ("Applicable Law" shall mean all applicable Federal, state, local
and foreign laws, ordinances, judgments, decrees, injunctions, writs, rules,
regulations, orders, licenses, and permits of any governmental agency). The
remedies of Holder provided herein, in the Aircraft Security Agreement and under
Applicable Law shall be cumulative and concurrent and may be pursued singly,
successively or concurrently at the sole discretion of Holder and may be
exercised as often as occasion therefor shall occur.  The failure to
exercise, or any delay in the exercise of, any right or remedy shall in no event
be construed as a waiver, release or exhaustion of any such
remedies.
