Stockholders' Equity | 9. STOCKHOLDERS’ EQUITY Common Stock Issued, Net of Issuance Costs Reverse Stock Split Immediately following the close of trading on March 7, 2016, the Company effected a one-for-twelve reverse stock split of its common stock. With the reverse stock split, every twelve shares of the Company’s issued and outstanding common stock were combined into one issued and outstanding share of common stock. The reverse stock split reduced the number of shares outstanding from approximately 61.8 million shares to approximately 5.2 million shares. In addition, effective upon the reverse stock split, the number of authorized shares of the Company’s common stock was reduced from 200 million to 100 million. The reverse stock split did not have any effect on the par value of the Company’s common stock. No fractional shares were issued as a result of the reverse stock split. Any fractional shares that would have resulted were settled in cash. All share data herein has been retroactively adjusted for the reverse stock split. Registered Direct Offerings On February 3, 2016, URI and Aspire Capital entered into a stock purchase agreement whereby URI sold 296,666 shares of its common stock in a registered direct offering for gross and net proceeds of $0.8 million. There were no underwriting discounts or placement agent fees. On April 4, 2016, URI and Aspire Capital completed a registered direct offering whereby URI sold 375,000 shares of its common stock at a price of $2.17 per share and 200,000 pre-funded common stock purchase warrants at a price of $2.16 per warrant, which was paid at closing. Gross proceeds from the offering were $1.2 million, including $0.4 million from the sale of the pre-funded warrants. The warrants have an exercise price of $0.01 per share and a term of three years. On June 3, 2016, Aspire Capital exercised all outstanding common stock purchase warrants and the Company issued 200,000 shares of common stock to Aspire Capital as a result. Common Stock Purchase Agreement with Aspire Capital On April 8, 2016, the Company entered into the CSPA with Aspire Capital to place up to $12.0 million in the aggregate of the Company’s common stock on an ongoing basis when required by the Company over a term of 30 months. The Company will control the timing and amount of sales to Aspire Capital, and at a price based on market prices at that time. As consideration for Aspire Capital entering into the purchase agreement, the Company issued 240,000 shares of its common stock to Aspire Capital upon the Company’s receipt of stockholder approval at its Annual General Meeting of Stockholders which was held on June 7, 2016. Following effectiveness of an S-1 registration statement relating to the resale of the shares subject to the CSPA on June 3, 2016 and receipt of stockholder approval for the issuance of up to 5.0 million shares of its common stock on June 7, 2016, the Company began selling shares of its common stock to Aspire Capital under the terms of the CSPA. During the year ended December 31, 2016, the Company sold 4,760,000 shares of common stock for net proceeds of $6.7 million under the CSPA. As of March 2, 2017, approximately $4.3 million of the aggregate $12.0 million remained available for future sales under the CSPA. The Company would need to obtain stockholder approval before issuing additional shares to Aspire Capital. Option Agreement On February 3, 2016, the Company issued 75,000 shares of common stock, with a fair value on the date of issuance of $0.3 million, to Aspire Capital as consideration for Aspire Capital entering into an option agreement (the “Option Agreement”) by which Aspire Capital granted the Company the right at any time or times prior to April 30, 2017 to require Aspire Capital to enter into up to two common stock purchase agreements, each having a term of up to 24 months and collectively requiring Aspire Capital to purchase up to $10 million in the aggregate of our common stock at such times and in such amounts as elected by the Company under the terms of the option agreement. The parties terminated the Option Agreement upon entering into the CSPA. At-the-Market Sales On October 31, 2011, the Company entered into an At-The-Market Sales Agreement with BTIG LLC (the “ATM Sales Agreement”), a global securities trading firm that acts as our sales agent. Under the ATM Sales Agreement, the Company may from time to time sell shares of its common stock having an aggregate offering amount up to $15.0 million in “at-the-market” offerings, which shares are registered under the Company’s currently effective registration statement on Form S-3. The Company filed a prospectus supplement dated November 17, 2015 with the Securities and Exchange Commission in connection with the offering, relating to shares of its common stock having an aggregate offering price of up to $6.0 million. The Company pays BTIG a commission equal to 3.0% of the gross proceeds from the sale of any shares pursuant to the ATM Sales Agreement. During the year ended December 31, 2016 the Company sold 3,298,396 shares of common stock for net proceeds of $5.8 million under the ATM Sales Agreement. As of December 31, 2016, the Company had fully utilized its ATM Sales Agreement and, as a result, no capacity remained available for future sales. Common Stock Issued for Extinguishment of Debt As discussed in Note 6, above, on December 5, 2016 the Company issued 2,487,562 shares of its common stock to Esousa in exchange for the retirement of $2.5 million in principal of the Company’s RCF Loan.

This $5.8 million increase represents the $2.5 million principal amount that was extinguished and the $3.3 million loss recorded upon the extinguishment of the debt. Common Stock Issued for RCF Loan Interest and Fees As discussed in Note 6 above, unless RCF elects to receive cash, RCF receives common shares of the Company for the payment of interest owing on the RCF Loan. For the year ended December 31, 2016, the Company issued 38,086 shares of common stock for the payment of $0.2 million in accrued interest and fees for the three-month period ended December 31, 2015.
