Exhibit 10.31
PROMISSORY NOTE
| Principal Amount: $10,000 | Issue Date: June 11, 2010 |
FOR VALUE RECEIVED, XStream System, Inc., a Delaware corporation (the “Borrower”), with principal
offices at 00000 000xx Xxxxxxx, Xxxxx 000, Xxxxxxxxx, XX 00000, hereby promises to pay to the order
of Xxxxx Xxxxx, an individual, residing at ___________________________________ (the “Lender”), on order, without demand, the principal sum of ten thousand dollars and
00/100 ($10,000.00)(the “Loan”) together with interest on the unpaid principal amount until paid in
full, at the rate set forth hereunder. Unless retired earlier, this Promissory Note (the “Note”)
shall mature and the principal sum due hereunder, together with all accrued and unpaid interest
thereon and other sums due hereunder, if any, shall become due and payable in full on the closing
date of the Borrower’s initial public offering (the “Maturity Date”).
1. Interest Rate. The aggregate unpaid principal balance of the Loan shall bear
interest at a fixed rate equal to the one-month LIBOR rate on the date hereof, thirty-five
hundredths of one percent (0.35%), plus two percent (2%), until all sums due hereunder are paid in
full.
2. Interest Payments. All interest hereunder shall be due and payable on the Maturity
Date.
3. Prepayment. This Note may be prepaid in full or in part at any time without notice
or penalty to the Borrower, in its sole discretion.
4. Service Charge. If any payment of principal is not made when due, the Borrower will
automatically owe the Lender a service charge equal to five percent (5%) of any payment of
principal not paid on the date when due. The Borrower acknowledges that the aforesaid late payment
fees are not imposed as a charge for the use of money, but rather are imposed to permit the Lender
to recoup administrative charges, additional overhead and other costs in dealing with loans not
paid on time, and the late payment fees provided for hereunder shall in no way be deemed an
interest charge.
5. Successors and Assigns. All of the terms and provisions of this Note shall be
binding upon, inure to the benefit of and be enforceable by each of the parties hereto, and their
respective successors, heirs, personal representatives, and permitted assigns.
6. Severability. If any part of this Note is adjudged illegal, invalid or
unenforceable, such invalidity or unenforceability shall not affect any other provision of this
Note that can be given effect without such provision.
7. Governing Law. This Note shall be governed by, and construed in accordance with,
the laws of the State of Florida.
8. Amendments. This Note may not be varied, amended or modified except in writing
signed by the Borrower and the Lender.
