ITEM 4. PURPOSE OF THE TRANSACTION.

The information set forth in Items 3 and 6 of this Statement is hereby incorporated by reference into this Item 4.

The Reporting Persons acquired the securities reported herein for investment purposes and intend to review their investments in the Company on a continuing basis. Depending on various factors, including but not limited to the Company’s financial position and strategic direction, price levels of the Common Stock, conditions in the securities markets, various laws and regulations applicable to the Company and companies in its industry and the Reporting Persons’ ownership in the Company and position as lender to the Company, and general economic and industry conditions, the Reporting Persons may in the future take actions with respect to their investment in the Company as they deem appropriate, including changing their current intentions, with respect to any or all matters required to be disclosed herein. Without limiting the foregoing, and subject to any applicable limitations described in Item 6 below, the Reporting Persons may, from time to time, acquire or cause affiliates to acquire additional shares of Common Stock or other securities of the Company (including any combination or derivative thereof), dispose, or cause affiliates to dispose, of some or all of their Common Stock or other securities of the Company or continue to hold, or cause affiliates to hold, Common Stock or other securities of the Company.


CUSIP NO. 393704309		13D/A		Page 13 of 17 Pages

In addition, the Reporting Persons have had and intend to continue having discussions, from time to time, with management and the board of directors of the Company, and may engage with other stockholders or securityholders of the Company and other relevant parties, or take other actions concerning, the Company’s business, lines of business, operations, strategy, previously announced restructuring, plans and prospects; any extraordinary corporate transactions (including, but not limited to, a merger, reorganization or liquidation); sales of a material amount of assets or divestitures; a change in the board of directors or management; a material change in the capitalization or dividend policies; other material changes in the Company’s business, lines of business, or corporate structure; or similar actions.

Except as set forth herein, or as would occur upon completion of any of the matters discussed herein, the Reporting Persons have no present plans, proposals or intentions which would result in or relate to any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Although the foregoing reflects activities presently contemplated by the Reporting Persons and each other individuals named in Item 2 with respect to the Company, the foregoing is subject to change at any time.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

(a)-(b) The information contained on the cover pages of this Schedule 13D is incorporated herein by reference.

The Reporting Persons beneficially own in the aggregate 22,351,569 shares of Common Stock, which represents approximately 38.0% of the outstanding shares of Common Stock. All calculations of percentage ownership in this Schedule 13D are based on 58,761,944 shares of Common Stock outstanding. This is composed of i) 42,774,011 shares of Common Stock outstanding as of August 28, 2023, as reported by the Issuer in its Form 6-K filed on August 29, 2023; ii) 3,014,354 shares issuable to the Reporting Persons upon the exercise of conversion instruments; and iii) 12,973,579 shares issuable to the Reporting Persons upon the conversion of the Subordinated Convertible Notes and the Additional Subordinated Convertible Notes.

Each of the Funds directly holds the number and percentage of shares of Common Stock disclosed as beneficially owned by it in the applicable table set forth on the cover page to this Statement. Madryn, as the investment manager for each of the Funds, and the Advisors, as the general partners for each of the Funds, may be deemed to have the shared power to direct the voting and disposition of shares of Common Stock beneficially owned by the Funds and, consequently, Madryn and the Advisors may be deemed to possess indirect beneficial ownership of such shares. Madryn and the Advisors disclaim beneficial ownership of such shares for all other purposes.

The responses of the Reporting Persons to rows 7, 8, 9, 10, 11 and 13 on the cover pages of this Statement are incorporated herein by reference.

To the knowledge of the Reporting Persons, none of the Covered Persons directly owns any shares of Common Stock; provided, however, that because of each Covered Persons’ status as a director, executive officer, manager, member or partner of a Reporting Person, a Covered Person may be deemed to be the beneficial owner of the shares of Common Stock beneficially owned by such Reporting Person. Except to the extent of their pecuniary interest, each of the Covered Persons disclaims beneficial ownership of the shares of the Common Stock reported herein and the filing of this Schedule 13D shall not be construed as an admission that any such Covered Person is the beneficial owner of any securities covered by this statement.

(c) Except as described herein, none of the Reporting Persons or, to their knowledge, none of the Covered Persons, has had any transactions in the Common Stock during the past 60 days.


CUSIP NO. 393704309		13D/A		Page 14 of 17 Pages

(d) Except as set forth herein, to the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any shares of Common Stock.

(e) Not applicable.
