(Alphabet Inc., together with 2016 GP, 2016 LLC, Alphabet Holdings, and XXVI may be collectively referred to as the “2016 Partnership Affiliates”). Each of the 2016 Partnership Affiliates may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 of the Securities Exchange Act of 1934 (as amended, the “Exchange Act”)) the securities directly beneficially owned by the 2016 Partnership. Furthermore, the 208,697 shares reported in the table above represent the beneficial ownership after giving effect to the Issuer’s 1-for-16 reverse stock split (the “Reverse Stock Split”) of its Common Stock that occurred on September 11, 2023, which was reported by the Issuer in its Current Report on Form 8-K, under Item 3.03, filed with the Securities and Exchange Commission (the “SEC”) on September 12, 2023.

(2)

Calculated in accordance with Rule 13(d)-3(d)(1)(i) promulgated under the Exchange Act and based on an aggregate 14,817,762 shares of the Issuer’s Common Stock outstanding as of November 9, 2023 as reported by the Issuer in its Quarterly Report for the period ended September 30, 2023, filed on Form 10-Q with the SEC on November 9, 2023. For the avoidance of doubt, pursuant to Rule 13d-1(b)(2), the reported percentage does not give effect to the additional 14,500,500 shares of Common Stock reportedly sold by the Issuer pursuant to a private placement on January 22, 2024, as reported by the Issuer on its Current Report on Form 8-K, filed with the SEC on January 22, 2024.

Item 4.

Ownership.

Provide the following information regarding the aggregate number and percentage of the class of securities of the Issuer identified in Item 1.

	(a)	Amount Beneficially Owned:

Reference to “beneficial ownership” of securities for purposes of this Amendment shall be understood to refer to beneficial ownership as that term is defined in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

As of December 31, 2023, the Reporting Persons may be deemed to beneficially own an aggregate 208,697 shares of the Issuer’s Common Stock.

As of December 31, 2023, the 2016 Partnership was the direct beneficial owner of all of the shares of Common Stock described in the preceding paragraph. 2016 GP is the general partner of the 2016 Partnership, and 2016 LLC is the general partner of 2016 GP.

As such, 2016 GP, 2016 LLC, Alphabet Holdings, XXVI, and Parent may each be deemed to indirectly beneficially own the securities that are directly beneficially owned by the 2016 Partnership.

Notwithstanding, the filing of this Amendment shall not be construed as an admission by any of the Reporting Persons, for purposes of Sections 13(d) or 13(g) of the Exchange Act or otherwise, as to beneficial ownership of the securities held by such entities.

CUSIP No.  252828108	Page 17 of 19

	(b)	Percent of Class:

As of December 31, 2023, the Reporting Persons, each individually and collectively as a group, were deemed to directly or indirectly beneficially own 1.4% of the Issuer’s outstanding Common Stock.

The aforementioned percentage was calculated in accordance with Rule 13(d)-3(d)(1)(i) promulgated under the Exchange Act and based on an aggregate total of 14,817,762 shares of the Issuer’s Common Stock outstanding as of November 9, 2023 as reported by the Issuer in its Quarterly Report for the period ended September 30, 2023, filed on Form 10-Q with the SEC on November 9, 2023. For the avoidance of doubt, pursuant to Rule 13d-1(b)(2), the reported percentage does not give effect to the additional 14,500,500 shares of Common Stock reportedly sold by the Issuer pursuant to a private placement on January 22, 2024, as disclosed by the Issuer in its Current Report on Form 8-K, filed with the SEC on January 22, 2024.
