1 Represents 104,294 shares of Common Stock purchased by LPC Fund directly from the Issuer in a private placement transaction completed on May 30, 2019 (the “May 2019 Private Placement”). The amount beneficially owned excludes 182,515 shares of Common Stock underlying warrants that were also purchased by LPC Fund from the Issuer on the same date in the May 2019 Private Placement, because such warrants cannot be exercised prior to November 30, 2019 (the “Initial Exercise Date”), which is more than 60 days after the date of this statement. Such warrants may be exercised for a period of five years following the Initial Exercise Date at an exercise price of $5.062 per share (subject to adjustment as provided in the warrants), subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of the warrants to the extent such issuance would cause the holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock. The warrants include a customary “cashless” exercise provision, which may be used to acquire underlying shares of Common Stock if at the time of exercise an effective registration statement registering the resale of such shares under the Securities Act of 1933, as amended (the “Securities Act”), is not available to the warrant holder.

2 Based on information contained in the Issuer’s registration statement on Form S-3 filed with the Securities and Exchange Commission (the “SEC”) on June 3, 2019, there were a total of 1,598,218 shares of Common Stock outstanding as of May 30, 2019, which number of outstanding shares includes the 104,294 shares of Common Stock that were purchased by LPC Fund directly from the Issuer on May 30, 2019 in the May 2019 Private Placement and excludes the 182,515 shares of Common Stock currently underlying the warrants that were also purchased by LPC Fund in the May 2019 Private Placement, because such warrants cannot be exercised prior to the Initial Exercise Date, which is more than 60 days after the date of this statement.

As of June 7, 2019, LPC Fund beneficially owns, directly, the following securities of the Issuer, all of which were purchased by LPC Fund directly from the Issuer on May 30, 2019 in the May 2019 Private Placement: (i) 104,294 shares of Common Stock, all of which shares are currently outstanding, and (ii) warrants to purchase up to 182,515 shares of Common Stock, none of which shares are currently outstanding. Pursuant to Rule 13d-3(d)(1)(i) under the Exchange Act, as of June 7, 2019, LPC Fund does not beneficially own the 182,515 shares of Common Stock underlying the warrants purchased by LPC Fund in the May 2019 Private Placement, because such warrants are not exercisable until the Initial Exercise Date of November 30, 2019 and, therefore, none of the shares of Common Stock underlying the warrants may be acquired by LPC Fund within 60 days of June 7, 2019. After the Initial Exercise Date, the warrants may be exercised for a period of five years thereafter, at an exercise price of $5.062 per share (subject to adjustment as provided in the warrants), subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of the warrants to the extent such issuance would cause the warrant holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock. The warrants include a customary “cashless” exercise provision, which may be used to acquire underlying shares of Common Stock if at the time of exercise an effective registration statement registering the resale of such shares under the Securities Act is not available to the warrant holder.
