Item 1.01 Entry Into a Material Definitive Agreement.

On February 1, 2012, Jones Soda Co. (the “Company”) entered into a Securities Purchase Agreement by and among the Company and certain purchasers named therein (the “Purchasers”), pursuant to which the Company agreed to issue to the Purchasers in a registered offering up to 6,415,000 shares of its common stock (the “Common Stock”) and warrants to purchase up to 3,207,500 shares of Common Stock (the “Warrants”). The securities will be sold in units, consisting of one share of common stock and a warrant to purchase 0.5 of a share of common stock, at a price of $0.50 per unit, for an aggregate offering price of $3,207,500 (the “Offering”). The Purchase Agreement contains customary representations, warranties and indemnification by the Company. A copy of the Purchase Agreement is attached hereto as Exhibit 10.1 and incorporated herein by reference.

Each Warrant will have an exercise price of $0.70 per share, for total potential additional proceeds to the Company of up to approximately $2,245,250 upon exercise of the Warrants. The Warrants are exercisable at any time on or after the six-month anniversary of the closing date and have a five-year term. The Warrants are exercisable for cash or, solely in the absence of an effective registration statement, by cashless exercise. The exercise price of the Warrants is subject to adjustment in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions, and also upon any distributions to Company shareholders, business combinations, sale of substantially all assets and other fundamental transactions. The exercise of the Warrants is subject to certain beneficial ownership and other limitations set forth in the Warrants. A copy of the form of the Warrants is attached hereto as Exhibit 4.1 and incorporated herein by reference.

On January 26, 2012, the Company entered into a placement agent agreement with Rodman & Renshaw, LLC (the “Placement Agent Agreement”), pursuant to which the Placement Agent agreed to use its reasonable best efforts to arrange for the sale of registered securities of the Company. The Company has agreed to pay the Placement Agent an aggregate fee equal to 8% of the gross proceeds received in the offering. The Placement Agent Agreement contains customary representations, warranties, and indemnification by the Company. A copy of the Placement Agent Agreement is attached hereto as Exhibit 1.1 and incorporated herein by reference.

The net proceeds to the Company from the registered direct offering, after deducting the placement agent fee and the Company’s estimated offering expenses, and excluding the proceeds, if any, from the exercise of the Warrants issued in the Offering, are expected to be approximately $2.8 million. The Offering is expected to close on or about February 6, 2012.

The offer and sale of the Common Stock and Warrants (and the shares of Common Stock issuable upon exercise of the Warrants) are registered under the Securities Act of 1933 (the “Securities Act”), as amended, on a registration statement on Form S-3 (File No. 333-166556), which became effective on May 18, 2010. A copy of the opinion of Perkins Coie LLP relating to the legality of the issuance of the shares of Common Stock and the Warrants is attached hereto as Exhibit 5.1.

The foregoing summaries of the terms of the Placement Agent Agreement, the Securities Purchase Agreement and the Warrants are subject to, and qualified in their entirety by, such documents attached hereto as Exhibits 1.1, 10.1 and 4.1, respectively, and incorporated herein by reference.
