    payable dated August 6, 2012. The Company entered into a purchase order (PO) financing agreement which provided $1,500,000
    in debt financing. This agreement also enabled us to receive a portion of the funds owed by customers in advance of when the
    customer is required to pay the balance (usually prior to shipment or delivery). We will be required to submit customer orders
    as collateral for the funds received under the agreement. Once the products are shipped and the end customer pays the remaining
    balance, those funds are then used to pay back the amount of the particular PO financed. The amount repaid is then available
    for us to borrow against other of our accounts receivable. The agreement calls for a 16% annual interest rate on any funds
    outstanding. As additional consideration for the financing agreement, we issued the financing party warrants to purchase up
    to 600,000 shares of our common stock, exercisable at any time during the 24 months from the date of issue, at an exercise
    price of $0.35 per share. The note was amended in March 2013 to include the outstanding accrued interest to date. Under the
    new terms, interest remains at 16%, and monthly principal payments are due as follows: month 1 - $275,000; month 4 and 5 -
    $30,000; months 6&amp;#150;11 - $60,000; and month 12 - $105,000. The May 31, 2013 balance is shown net of a $23,737 debt discount.&lt;/font&gt;&lt;/td&gt;

    due within five days of receipt by Company, in whole or in part, portion of funds collected on collateral sales order, or,
    Company may submit a new collateral sales order with value equal to or in excess of principal outstanding. Borrowings were
    originally due December 31, 2012, but notes were combined on April 1, 2013 under a simple promissory note due October 1, 2014.
    Under the new terms, interest remains at 16%, and monthly principal payments are due as follows: April 15, 2013 - month 1

    Interest rate is 10% annually. Under the note, outstanding accrued interest was added to principal as of the amendment date.&lt;/font&gt;&lt;/td&gt;
