Item 3. Source and Amount of Funds or Other Consideration.

The personal funds of the reporting person were the source of the funds for the purchase.

Item 4. Purpose of Transaction.

The reporting person acquired the Common Stock for investment purposes. Subject to applicable legal requirements, the reporting person may purchase additional securities of the Issuer from time to time in open market or private transactions, depending on her evaluation of the Issuer’s business, prospects and financial condition, the market for the Issuer’s securities, other developments concerning the Issuer, the reaction of the Issuer to the reporting person’s ownership of the Issuer’s securities, other opportunities available to the reporting person, and general economic, money market and stock market conditions. In addition, depending upon the factors referred to above, the reporting person may dispose of all or a portion of her securities of the Issuer at any time. The reporting person reserves the right to increase or decrease her holdings on such terms and at such times as she may decide.

Except as set forth in this Item 4, the reporting person has no present plans or proposals that relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. The reporting person intends to review her investment in the Issuer on a continuing basis. Depending on various factors, the reporting person may in the future, from time to time, dispose of some or all of the securities of the Issuer beneficially owned by her and/or acquire additional securities of the Issuer, in the open market or otherwise, or take any other actions with respect to her investment in the Issuer permitted by law, including any or all of the actions set forth in clauses (a) through (j) of Item 4 of Schedule D.

Item 5. Interest in Securities of the Issuer. 

(a) See Items 11 and 13 of the cover page, and the corresponding footnotes, for the reporting person.

(b) See Items 7 to 10 of the cover page for the reporting person and Item 2 of the Schedule 13D.

(c) The Issuer and certain holders, including the reporting person (collectively, the “Holders”), recently entered into warrant amendment and exercise agreements (the “Warrant Agreements”) with the Holders of the Issuer’s common stock purchase warrants, including the Issuer’s Series D, F, and G common stock purchase warrants (collectively, the “Warrants ”). Among other things, the Warrant Agreements lowered the exercise price of each of the Warrants to $0.80 per share (the “Reduced Exercise Price”) in order to induce the Holders to exercise their Warrants. For each Warrant exercised by a Holder at the Reduced Exercise Price, the Company agreed to reduce the exercise price of Warrants to purchase an equivalent number of shares of Common Stock to $0.79 (the “Amended Exercise Price”). Pursuant to the Warrant Agreement entered into between the Issuer and the reporting person, the reporting person exercised Warrants at the Reduced Exercise Price to purchase an aggregate of 519,827 shares of Common Stock. In addition, in connection with such exercises and pursuant to the Warrant Agreement, Warrants to purchase 519,827 shares of Common Stock held by the reporting person had their exercise prices reduced to $0.79 per share.

Additionally, pursuant to the Warrant Agreement entered into with the reporting person, the Issuer agreed to prepare and file with the SEC, as soon as practicable, but in no event later than November 4, 2019, a registration statement on Form S-3 to register all shares of Common Stock underlying all of the Warrants held by the reporting person. The Issuer received aggregate gross proceeds of approximately $1,200,000 from the transactions pursuant to the Warrant Agreements from all of the Holders.

The foregoing description of the Warrant Agreements are qualified in their entirety by reference to the full text of the form of Warrant Agreement, which will be filed as an exhibit to the Issuer’s Quarterly Report on Form 10-Q for the period ended September 30, 2019.

(d) To the knowledge of the Reporting Person, no one other than the Reporting Person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock covered by this statement.

(e) Not applicable.

Item 6. Contracts, Arrangements, Undertakings or Relationships with Respect to Securities of the Issuer.
