Item 3. Source and Amount of Funds or Other Consideration

The 3,727,273 shares of Common Stock were purchased by and are directly held by Zulu. The funds used to purchase the Common Stock came from the working capital of Zulu.

Item 4. Purpose of Transaction

Zulu acquired the shares of Common Stock as part of a strategic investment in the Issuer. On May 3, 2019, the Issuer entered into a Stock Purchase Agreement (the “Purchase Agreement”) with certain accredited investors (the “Investors”) in a private placement (the “Private Placement”) pursuant to which the Issuer sold an aggregate of 4,545,455 shares of Common Stock at a purchase price of $1.10 per share. The gross proceeds to the Issuer at the closing of the Private Placement are approximately $5.0 million.

Pursuant to the terms of the Purchase Agreement, the Investors agreed to certain lock-up restrictions on their ability to dispose of the Common Stock purchased in the Private Placement for 30 months following the closing date (the “Lock Up Period”), subject to certain exceptions. Pursuant to the terms of the Purchase Agreement, the Issuer is required to file a registration statement with the Securities and Exchange Commission within thirty (30) days of the closing of the Private Placement to register for resale the shares of Common Stock sold in the Private Placement. Pursuant to the terms of the Purchase Agreement, during the Lock Up Period, if the Issuer proposes to issue Common Stock or common stock equivalents for cash consideration of $500,000 or greater, in one or more transactions, with the primary purpose of raising capital (each, a “Subsequent Financing”), Zulu shall have the right to participate in each such Subsequent Financing in an amount necessary to maintain Zulu’s pro-rata ownership of the Issuer (calculated on a fully-diluted basis) on the same terms, conditions and price provided for in such Subsequent Financing.

The Issuer is required under the Purchase Agreement to appoint Mr. Jeremy P. Hitchcock and one individual designated by Zulu in the offering and approved by the Issuer’s Board of Directors (the “Board”), and to appoint replacements in the event of the designated directors’ resignation. The board designation rights will terminate upon Zulu ceasing to own at least 8% of the Issuer’s Common Stock on a fully diluted basis. Effective upon the closing of the Private Placement, the Board approved an increase in the size of the Board from five to seven members and appointed Mr. Jeremy P. Hitchcock and Mr. Jonathan Seelig to the Board to fill the resulting vacancies.

Except as set forth in this Schedule, Zulu has no present plans or proposals that relate to or would result in any of the actions described in Item 4(a) through (j) of Schedule 13D. Zulu and the Reporting Persons may evaluate on a continuing basis Zulu’s investment in the Issuer and expect that they may from time to time, subject to the terms of the Purchase Agreement, acquire or dispose of shares of Common Stock or other securities of the Issuer. Zulu may, subject to the terms of the Purchase Agreement, purchase or sell shares of Common Stock in the future, either on the open market or in private transactions, in each case, depending on a number of factors, including general market and economic conditions and other available investment opportunities. Depending on market conditions, general economic and industry conditions, the Issuer’s business and financial condition and/or other relevant factors, Zulu may, subject to the terms of the Purchase Agreement, develop other plans or intentions in the future relating to one or more of the actions described in Item 4(a) through (j) of Schedule 13D.

The foregoing discussion does not purport to be complete, and is qualified in its entirety by the terms and conditions of the Purchase Agreement, a copy of which is filed as Exhibit 10.1 to the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on May 6, 2019, and is incorporated herein by reference.
