PROMISSORY NOTE B

Exhibit 10.5

PROMISSORY NOTE B

FOR VALUE RECEIVED, the undersigned, CONSTITUTION TRAIL, LLC, a Nebraska limited liability company (“Borrower”), having an address in care of Dial Properties, Co, 11506 Nicholas Street, Suite 200, Omaha, Nebraska 68154, unconditionally promises to pay to the order, of M&I MARSHALL & ILSLEY BANK, having an address of 11301 Nall Avenue, Leawood, Kansas 66211 (together with its successors and assigns called “Lender”) the principal sum of $1,600,000.00, together with interest upon the principal balance remaining outstanding from time to time as set forth below, in payments as set forth below. The indebtedness evidenced by this Promissory Note B (the “Note B”) is referred to herein as the “Loan B”.

1. TERM. The “Maturity Date” of this Note B shall be the earlier of: a) April 5, 2015; or b) the date on which Lender exercises its right to accelerate the debt evidenced by this Note B upon the occurrence of an Event of Default (as defined below) and expiration of any applicable cure period (if any).

2. INTEREST.

2.1 Interest Rate. The “Note Rate” prior to the occurrence of an Event of Default shall be a fixed rate equal to six percent (6%). All interest shall be calculated for the actual number of days elapsed over a year assumed to Consist of 360 days, commencing on the date Lender disburses the $1,600,000.00.

2.2 Default Rate. At any time that an uncured Event of Default is outstanding, this Note B will bear interest at a rate of interest which is the lesser of five (5) percentage points in excess of the Note Rate from time to time or the maximum rate allowed by applicable law (“Default Rate”). The Default Rate shall be paid without prejudice to Lender’s rights to collect other amounts due under the Note B or to declare a default under any Loan Document (as defined below). If the Event of Default is cured interest will begin to accrue at the Note Rate commencing on the date the Event of Default is cured.

3. PAYMENTS. Borrower shall make payments according to the following paragraphs to Lender at its address appearing above or as later communicated to Borrower in writing, in immediately payable U.S. funds. All payments shall be first applied to Lender’s fees, costs, and expenses which are reimbursable under the terms of this Note B or any Loan Document (as defined below); then to accrued and unpaid interest; and finally to unpaid principal. If any payment due date is a Saturday, Sunday, or banking holiday observed by Lender, the due date of the payment shall automatically be extended to the next following banking business day.

3.1 Scheduled Interest and Principal Payments. On May 5, 2010 and continuing on the fifth (5th) day of each month thereafter through the Maturity Date (each a “Payment Date”), Borrower shall make monthly payments of principal and interest based upon a five (5) year amortization at the Note Rate, such payments to be applied first in payment of interest due on unpaid principal, and the balance to be applied in reduction of the principal.

3.2 Final Payment. All outstanding principal, accrued and unpaid interest, late payment charges, and other amounts chargeable under this Note B and the Loan Documents shall be due and payable in full on the Maturity Date.

3.3 Prepayment. Borrower shall be entitled to prepay this Note B in full or in part at any time without penalty.

4. LATE PAYMENT CHARGE. If Borrower fails to make any monthly payment within ten (10) days after the Payment Date, a late charge equal to five percent (5%) of the amount of any such payment (the “Late Payment Charge”) shall, to the extent now or hereafter permitted by law, become immediately due to Lender to defray the legal and administrative costs of collecting delinquent accounts. A tender to Lender of any monthly payment more than ten (10) days past the Payment Date which does not include the Late Payment Charge may be rejected as insufficient or Lender may accept the tendered amount as a partial payment without waiving Lender’s right to receive the Late Payment Charge. This Note B will remain in default and interest at the Default Rate will accrue until the Late Payment Charge is paid. The Late Payment Charge shall be paid without prejudice to Lender’s rights to collect other amounts due hereunder or to declare a default under this Note B or any other Loan Document.

5. SECURITY. This Note B shall be secured by the following instruments executed by Borrower and other individuals and entities on or about even date herewith, except as otherwise noted:

5.1 The Loan Documents; and

If any judgment is hereafter entered holding any

provision of this Note B to be invalid or unenforceable, then the remainder of this Note B shall not be affected by such judgment, and the remaining terms of this Note B shall be carried out as nearly as possible according to its original terms. g) The term “person” includes, but is not limited to, natural persons, corporations, partnerships, trusts, limited liability companies, joint ventures, and/or other legal entities. h) No inference in favor of, or against, any person shall be drawn from the fact that such person has drafted all or any part of this Note B or any other Loan Document. i) The term “modified” means amended, changed, extended, renewed, altered, terminated, or canceled.
