A.            The Company currently requires funds for product development and other general corporate purposes.

B.             The Purchaser is willing to advance funds to the Company in exchange for the issuance to it of a convertible promissory note evidencing the Company’s obligation to repay the Purchaser’s loan of the advanced funds, all as provided in this Agreement.

NOW THEREFORE, the parties hereby agree as follows:

ARTICLE 1

PURCHASE, SALE AND TERMS OF NOTE

1.01         The Note. The Company has authorized the issuance and sale to the Purchaser of the Company’s Convertible Promissory Note, in the original aggregate principal amount of $1,500,000, in the form attached hereto as Exhibit A (the “Note”).

1.02         Purchase and Sale of the Note.

(a)     The Closing. The Company agrees to issue and sell to the Purchaser, and, subject to and in reliance upon the representations, warranties, covenants, terms and conditions of this Agreement, the Purchaser agrees to purchase the Note in the principal amount of $1,500,000 (such amount, the “Purchase Price”). Such purchase and sale shall take place at a closing (the “Closing”) to be held at the Washington D.C. offices of Goodwin Procter LLP, on the date hereof at 12:00 p.m., local time, or at such other time or place as may be mutually agreed upon by the Company and the Purchaser. At the Closing, the Purchaser will deliver to the Company, as payment in full for the Note to be purchased by the Purchaser at the Closing, an amount equal to the Purchase Price by wire transfer of immediately available funds to the Company. At the Closing, the Company will issue and deliver to the Purchaser the duly executed Note. The Company shall send the Note to the Purchaser at the address furnished to the Company for that purpose.

1.03         No Usury. Each of this Agreement and the Note issued pursuant to the terms of this Agreement is hereby expressly limited so that in no event whatsoever, whether by reason of deferment or advancement of loan proceeds, acceleration of maturity of the loan evidenced hereby, or otherwise, shall the amount paid or agreed to be paid to the Purchaser hereunder for the loan, use, forbearance or detention of money exceed the maximum interest rate permitted by the laws of the State of New York. If at any time the performance of any provision hereof or any Note involves a payment exceeding the limit of the price that may be validly charged for the loan, use, forbearance or detention of money under applicable law, then automatically and retroactively, ipso facto, the agreed upon interest rate as set forth in the Note shall be reduced to such limit, it being the specific intent of the Company and the Purchaser hereof that all payments by the Company under the Note shall be applied first to any fees and expenses due and payable thereunder, then to the accrued interest due and payable thereunder and the remainder, if any, to the outstanding principal. All payments by the Company under the Note shall be made without set-off or counterclaim and be free and clear and without any deduction or withholding for any taxes or fees of any nature whatever, unless the obligation to make such deduction or withholding is imposed by law.
