($            ) (or such lesser amounts as may be outstanding from time to time under this Note) on the Maturity Date, as defined in Section 1 below. Unless otherwise set forth herein,
all references to $ means United States dollars. 
 This Note is one of a series of Secured Promissory Notes made of even date

“Notes”). 
 1. Maturity. This Note shall be due and payable upon the earlier to occur (the “Maturity
Date”) of: (i) March 8, 2010, in the event the Buyers do not purchase substantially all of the assets of Kuchera from Kuchera by February 26, 2010, and (b) January [20] [22], 2013. 

2. Interest. Interest shall accrue on the unpaid principal balance hereof and on any interest payment that is not made when due at
the rate of fifteen percent (15%) per annum (the “Base Rate”) until the principal amount of this Note is paid in full. Accrued interest shall be due and payable quarterly, on the last day of each calendar quarter,
March 31, June 30, September 30 and December 31, of each year, with a final payment of accrued and unpaid interest due and payable on the Maturity Date. Upon the occurrence and during the continuation of an Event of
Default (as defined herein) interest shall accrue on all unpaid amounts due hereunder, including without limitation interest, at the rate of the Base Rate plus three percent (3%). If a judgment is entered against the Company on this Note, the amount
of the judgment so entered shall bear interest at the highest rate authorized by law as of the date of the entry of the judgment. 

 3. Payments. Payments of both principal and interest shall be made at the principal
executive office of the Company, or such other place as the holder hereof shall designate to the Company in writing, in lawful money of the United States of America. Payments shall be made pro rata among all holders of Notes in accordance with the
outstanding principal balances of their Notes. 
 So long as no Event of Default has occurred in this Note, all payments
hereunder shall first be applied to interest, then to principal. Upon the occurrence of an Event of Default in this Note, all payments hereunder shall first be applied to costs pursuant to Section 11.4, then to interest and the remainder to
principal. 
 4. Registration, Transfer and Exchange of Notes. The Company will keep at its principal office a register

exchange (accompanied in the case of registration of transfer or exchange by a written instrument of transfer in form satisfactory to the Company duly executed by or on behalf of the holder), the Company, at its expense, will deliver in exchange one
or more new notes in denominations of $10,000 or larger multiples of $1,000, as requested by the holder for the aggregate unpaid principal amount. Any note or notes issued in a transfer or exchange shall carry the same rights to increase notes
surrendered. The Holder agrees that prior to making any sale, transfer, pledge, assignment, hypothecation, or other disposition (each, a “Transfer”) of this Note, the Holder shall give written notice to the Company describing the manner in
which any such proposed Transfer is to be made and providing such additional information and documentation regarding the Transfer as the Company reasonably requests. If the Company so requests, the Holder shall at his expense provide the Company
with an opinion of counsel (which counsel must be reasonably satisfactory to the Company), in form and substance satisfactory to the Company, that the proposed Transfer complies with applicable federal and state securities laws. The Company shall
have no obligation to Transfer this Note unless the Holder thereof has complied with the foregoing provisions, and any such attempted Transfer shall be null and void. 

5. Registered Owner. Prior to due presentation for registration of transfer, the Company may treat the person in whose name this
Note is registered as the owner and holder of such Note for the purpose of receiving payment of principal of, and interest on, such Note and for all other purposes. 

6. Prepayment. 

6.1 Optional Prepayment. The Company, at its option, may prepay in whole or in part the principal amount of this
Note at any time; provided, however that if any such prepayment occurs (a) on or before January [20] [22], 2011 (the “Anniversary Date”) and such Prepayment Date is not the Maturity Date, the Company shall pay to Holder an additional
amount equal to the amount of interest that would have accrued on such prepaid amount from and after such Prepayment Date through the Anniversary Date or (b) on any date after the Anniversary Date but prior to the Maturity Date, the Company
shall pay to Holder an additional amount equal to 2% of such prepaid amount (the

pre-payment of this Note (the “Prepayment Notice”). The Prepayment Notice shall specify the date upon (“Prepayment Date”) and the place at which, payment may be obtained and shall call upon the Holder to surrender this Note to
the Company in the manner and at the place designated. On the Prepayment Date, the Holder shall surrender this Note to the Company in the manner and at the place designated in the Prepayment Notice, and thereupon prepayment shall be made to Holder
and this Note shall be cancelled. In the event that less than all the principal amount of this Note is prepaid, upon surrender of this Note to the Company, the Company shall execute and deliver to Holder a new note or notes in principal amount equal
