Item 1.01 Entry into a Material Definitive Agreement.

On July 27, 2016, we entered into a purchase agreement (the “Purchase Agreement”), together with a registration rights agreement (the “Registration Rights Agreement”), with Lincoln Park Capital Fund, LLC (“Lincoln Park”), an Illinois limited liability company. Upon signing the Purchase Agreement, LPC agreed to purchase 133,690 shares of our common stock for $500,000 as an initial purchase under the agreement.

Under the terms and subject to the conditions of the Purchase Agreement, we have the right to sell to and Lincoln Park is obligated to purchase up to an additional $10.0 million in amounts of shares, as described below, of our common stock (“Common Stock”), subject to certain limitations, from time to time, over the 36-month period commencing on the date that a registration statement, which we agreed to file with the Securities and Exchange Commission (the “SEC”) pursuant to the Registration Rights Agreement, is declared effective by the SEC and a final prospectus in connection therewith is filed. We may direct Lincoln Park, at its sole discretion and subject to certain conditions, to purchase up to 10,000 shares of Common Stock on any business day (such purchases, “Regular Purchases”), provided that at least one business day has passed since the most recent purchase, and provided that the amount we may sell to Lincoln Park under a single Regular Purchase may increase under certain circumstances as described in the Purchase Agreement but in no event will the amount of a single Regular Purchase exceed $500,000. The purchase price of shares of Common Stock related to the future funding will be based on the prevailing market prices of such shares at the time of sales. In addition, we may direct Lincoln Park to purchase additional amounts as accelerated purchases if on the date of a Regular Purchase the closing sale price of the Common Stock is not below the threshold price as set forth in the Purchase Agreement. Our sales of shares of Common Stock to Lincoln Park under the Purchase Agreement are limited to no more than the number of shares that would result in the beneficial ownership by Lincoln Park and its affiliates, at any single point in time, of more than 4.99% of the then outstanding shares of Common Stock which amount may be increased to an amount not more than 9.99% of the then outstanding shares of Common Stock by written notice to us by Lincoln Park, effective 61 days after delivery of such notice.

The Purchase Agreement and the Registration Rights Agreement contain customary representations, warranties, agreements and conditions to completing future sale transactions, indemnification rights and obligations of the parties. We have the right to terminate the Purchase Agreement at any time, at no cost or penalty. Actual sales of shares of Common Stock to Lincoln Park under the Purchase Agreement will depend on a variety of factors to be determined by us from time to time, including, among others, market conditions, the trading price of the Common Stock and determinations by us as to the appropriate sources of funding for us and our operations. Lincoln Park has no right to require any sales by us, but is obligated to make purchases from us as it directs in accordance with the Purchase Agreement. Lincoln Park has covenanted not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of our shares.

The net proceeds under the Purchase Agreement to us will depend on the frequency and prices at which we sell shares of our stock to Lincoln Park. We expect that any proceeds received by us from such sales to Lincoln Park under the Purchase Agreement will be used for general corporate purposes and working capital requirements.

In connection with the Purchase Agreement, we issued as a commitment fee to Lincoln Park 52,500 shares of Common Stock. Lincoln Park represented to us, among other things, that it was an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”)), and we sold the securities in reliance upon an exemption from registration contained in Section 4(2) under the Securities Act. The securities sold may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

Joseph Gunnar & Co., LLC (“Joseph Gunnar”) and Fordham Financial Management, Inc. (“Fordham”) acted as Financial Advisor on our behalf. Upon the execution of the Purchase Agreement, we paid $50,000 to Joseph Gunnar and $50,000 to Fordham. Upon the earlier of six months from the execution of the Purchase Agreement or upon the effectiveness of the resale registration statement to be filed pursuant to the Registration Rights Agreement, we will pay an additional $50,000 to Joseph Gunnar and $50,000 to Fordham.

This current report on Form 8-K shall not constitute an offer to sell or a solicitation of an offer to buy any shares of Common Stock, nor shall there be any sale of shares of Common Stock in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.

The foregoing descriptions of the Purchase Agreements and the Registration Rights Agreement are qualified in their entirety by reference to the full text of the Purchase Agreement and the Registration Rights Agreement, copies of which are attached hereto as Exhibit 10.1 and 10.2, respectively, and each of which is incorporated herein in its entirety by reference. The representations, warranties and covenants contained in such agreements were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such agreements, and may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures exchanged between the parties in connection with execution of the agreements.
