Litigation The Company is involved in various legal matters that have arisen in the ordinary course of business. While the ultimate outcome of these matters is not presently determinable, it is the opinion of management that the resolution will not have a material adverse effect on the financial position or results of operations of the Company. Potential Liability Related to Issuances of Equity Securities The Company may have potential liability for certain sales, offers or issuances of equity securities of the Company in possible violation of federal securities laws. Pursuant to a Registration Statement on Form S-1 (Registration No. 333-208676), declared effective on February 16, 2016 (the 2016 Registration Statement), the Company sought to register: a primary offering of up to $4,000,000 units, the Common Stock included as part of the units, the warrants included as part of the units, and the Common Stock issuable upon exercise of such warrants; a primary offering of up to $400,000 placement agent warrants and the Common Stock issuable upon exercise of such placement agent warrants; and a secondary offering of 23,545,144 shares of Common Stock held by certain selling stockholders named in the 2016 Registration Statement. The SEC Staffs interpretations provide that, when an issuer is registering units composed of common stock, common stock purchase warrants, and the common stock underlying the warrants, the registration fee is based on the offer price of the units and the exercise price of the warrants. The registration fee paid did include the fee based on the offer price of the units, allocated to the unit line item in the fee table. Although the fee table in the 2016 Registration Statement included a line item for the Common Stock underlying the warrants, the Company did not include in that line item the fee payable based on the exercise price of $0.08 per share for such warrants, which amount should have been allocated to such line item based on the SEC Staffs interpretations. As a result, a portion of the securities intended to be registered by the 2016 Registration Statement was not registered. In addition, in a post-effective amendment to the 2016 Registration Statement filed on September 23, 2016, too many placement agent warrants were inadvertently deregistered. The post-effective amendment stated that the Company had issued $180,100, based on 2,251,250 Class L warrants issued with a $0.08 exercise price of warrants to the placement agent and therefore deregistered $219,900, based on 2,748,750 Class L warrants issued with a $0.08 exercise price of placement agent warrants from the $400,000, based on 5,000,000 Class L warrants issued with a $0.08 exercise price total offering amount included in the Registration Statement. The actual warrants issued to the placement agent totaled $240,133.36, based on 3,001,667 Class L warrants issued with a $0.08 exercise price, and only $159,867, based on 1,998,338 Class L warrants issued with a $0.08 exercise price should have been deregistered in such post-effective amendment. To the extent that we have not registered or failed to maintain an effective registration statement with respect to any of the transactions in securities described above and with respect to our ongoing offering of shares of Common Stock underlying the warrants, and a violation of Section 5 of the Securities Act did in fact occur or is occurring, eligible holders of our securities that participated in these offerings would have a right to rescind their transactions, and the Company may have to refund any amounts paid for the securities, which could have a materially adverse effect on the Companys financial condition. Eligible securityholders have not filed a claim against the Company alleging a violation of Section 5 of the Securities Act with respect to these transactions, but they could file a claim in the future. Furthermore, the ongoing offering of and issuance of shares of Common Stock underlying certain of our warrants from the 2016 Registration Statement may have been, and may continue to be, in violation of Section 5 of the Securities Act and the rules and regulations under the Securities Act, because we did not update the prospectus in the 2016 Registration Statement for a period of time after the 2016 Registration Statement was declared effective and because our reliance on Rule 457(p) under the Securities Act in an amendment to our Registration Statement on Form S-1 (Registration No. 333-213774) filed on September 23, 2016 effected a deregistration of the securities registered under the 2016 Registration Statement. Eligible securityholders have not filed a claim against the Company alleging a violation of Section 5 of the Securities Act, but they could file such a claim in the future. If a violation of Section 5 of the Securities Act did in fact occur or is occurring, eligible securityholders would have a right to rescind their transactions, and the Company may have to refund any amounts paid the securities, which could have a materially adverse effect on the Companys financial condition.
