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

On October 3, 2023, the Issuer completed the closing of an underwritten offering (the “Offering”) of 3,921,928 shares of Common Stock, pre-funded warrants to purchase up to 3,472,435 shares of Common Stock (the “Pre-Funded Warrants”) and accompanying common stock warrants to purchase up to 7,394,363 shares of Common Stock (the “Purchase Warrants”). Each share of Common Stock was sold together with one Purchase Warrant at the public offering price of $2.84 per share, less underwriting discounts and commissions. At such closing, NEA 14 purchased an aggregate of 2,640,845 shares of the Issuer’s Common Stock at the Offering price of $2.84 per share with a corresponding number of Purchase Warrants exercisable at $3.408 per share (the “NEA 14 Purchase Warrants”). The NEA 14 Purchase Warrants are exercisable at the option of NEA 14 at any time after their issuance; provided, that the NEA 14 Purchase Warrants carry a limitation on exercise preventing NEA from exercise if such exercise results in NEA beneficially owning in excess of 4.99% (or, at the election of NEA 14, 9.99%) of the number of shares of the Issuer’s Common Stock, which percentage can be increased or decreased at the option of NEA 14 upon 61 days prior notice (the “Beneficial Ownership Limitation”).

Prior to the Offering and taking into account the 15-for-1 reverse stock split of the Issuer’s issued and outstanding Common Stock as of September 27, 2023 (as further described in the Issuer’s Form 8-K filed with the Securities and Exchange Commission (“SEC”) on September 28, 2023), NEA 14 held 281,929 shares of the Issuer’s Common Stock. After giving effect to the Beneficial Ownership Limitation, NEA 14 is now deemed to hold 2,922,774 shares of the Issuer’s Common Stock (the “NEA 14 Shares”).

The working capital of NEA 14 is the source of the funds for the purchase of the NEA 14 Shares. No part of the purchase price of the NEA 14 Shares is represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the NEA 14 Shares.

Item 5. Interest in Securities of the Issuer.

(a)

NEA 14 is the record owner of the NEA 14 Shares. As the sole general partner of NEA 14, NEA Partners 14 may be deemed to own beneficially the NEA 14 Shares. As the sole general partner of NEA Partners 14, NEA 14 LTD may be deemed to own beneficially the NEA 14 Shares. As members of NEA 14 LTD, each of the Directors may be deemed to own beneficially the NEA 14 Shares.

Each Reporting Person disclaims beneficial ownership of the NEA 14 Shares other than those shares which such person owns of record.

The percentage of outstanding Common Stock of the Issuer which may be deemed to be beneficially owned by each Reporting Person is set forth on Line 13 of such Reporting Person’s cover sheet. Such percentage was calculated based on the 8,496,185 shares of Common Stock reported to be outstanding immediately after the Offering on the Issuer’s prospectus filed under Rule 424(b)(4), filed with the SEC on October 2, 2023.

(b)

Regarding the number of shares as to which such person has:

(i)

sole power to vote or to direct the vote: See line 7 of cover sheets

(ii)

shared power to vote or to direct the vote: See line 8 of cover sheets

(iii)

sole power to dispose or to direct the disposition: See line 9 of cover sheets

(iv)

shared power to dispose or to direct the disposition: See line 10 of cover sheets

CUSIP No. 87166L209

(c)

(d)

No other person is known to have the right to receive or the power to direct the receipt of dividends from, or any proceeds from the sale of, Shares beneficially owned by any of the Reporting Persons.

(e)

Each of Barrett, Barris, Mott, Viswanathan and Sonsini has ceased to beneficially own five percent (5%) or more of the Issuer’s Common Stock as a result of ceasing to be a director of NEA 14 LTD.
