Subsequent Events	Note 10. Subsequent Event On June 30, 2017, the Company entered into a Securities Purchase Agreement with certain institutional investors (the “Purchasers”), pursuant to which the Company sold to the Purchasers, in a registered direct offering, an aggregate of 1,325,000 shares (the “Shares”) of common stock, par value $0.001 per share (the “Common Stock”) at a negotiated purchase price of $1.70 per share, for aggregate gross proceeds to the Company of approximately $2,252,500, before deducting fees to the placement agent and other estimated offering expenses payable by the Company. The Shares were offered by the Company pursuant to an effective shelf registration statement on Form S-3 (No. 333-19799). The registered direct offering was completed in July 2017. In a concurrent private placement, the Company also sold to each of the Purchasers a warrant to purchase one half of a share of the Common Stock for each Share purchased for cash in the offering, pursuant to a Common Stock Purchase Warrant, by and between the Company and each Purchaser (each, a “Warrant,” and collectively, the “Warrants”) representing in the aggregate rights to purchase 662,500 shares of common stock at the exercise price. The Warrants will be exercisable beginning on the six-month anniversary of the date of issuance (the “Initial Exercise Date”) at an exercise price of $2.35 per share and will expire on the five-year anniversary of the Initial Exercise Date. The exercise price and number of Warrant Shares will be subject to adjustment in the event of any stock dividend or split, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Warrants. The Warrants will be exercisable on a “cashless” basis if at any time after the six month anniversary there is not an effective registration statement for the resale of the Warrant Shares in place, or there is not a current resale prospectus then available.
