ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
Item 3 of the Schedule 13D is supplemented by the following:
Amendment No. 6 to this Schedule 13D filed on March 17, 2023, stated that L. John Doerr had sole voting power and sole dispositive power of 121,219
shares of Common Stock and beneficial ownership of 123,895,013 shares of Common Stock. These amounts incorrectly included 80,000 shares of Common Stock issuable upon the vesting of a restricted stock unit grant made by the Company to Mr. Doerr
on August 22, 2022, which is expected to vest in full on August 22, 2023, and excluded 8,292 shares of common stock issuable upon the vesting of a restricted stock unit grant made by the Company to Mr. Doerr on January 20, 2023
which vested in full on March 31, 2023. This Amendment No. 7 corrects these items.
ITEM 4. PURPOSE OF TRANSACTION.
Item 4 of the Schedule 13D is supplemented by the following:
Forbearance Agreement and Amendment to 2019 LSA, 2022 LSA and Perrara LSA
On May 9, 2023, the Company and certain of the Companys subsidiaries entered into forbearance agreements (each a Forbearance
Agreement) with each of FV and Perrara (the Lenders), pursuant to which the Lenders agreed to forbear from exercising certain of their respective rights and remedies related to certain payment defaults under the
following agreements during the forbearance period: (i) the 2019 LSA (ii) the 2022 LSA, and (iii) the Loan and Security Agreement (the Perrara LSA), dated March 10, 2023 (as amended, restated, supplemented or
otherwise modified from time to time), by and among the Company, certain subsidiaries of the Company party thereto, and Perrara.
The forbearance period
begins on May 9, 2023 and ends on June 23, 2023, subject to certain limited conditions, the occurrence of which would cause the forbearance period to end prior to June 23, 2023.
In exchange for each of the Lenders entering into a Forbearance Agreement, the Company agreed to certain conditions and covenants. In addition, pursuant to
the terms of the 2019 LSA, 2022 LSA and the Perrara LSA, default interest (Default Interest) accrues during an event of default. The Default Interest rate (i) equals 6.0% per annum under the 2019 LSA and 1.0% per annum under
the 2022 LSA and the Perrara LSA and (ii) applies retroactively to the Companys outstanding indebtedness under such agreements from and after March 24, 2023.
Charging Default Interest increases the amount of unpaid interest under the 2019 LSA and thus increases the number of shares of Common Stock issuable upon
conversion of the 2019 LSA.
Among other things, the Forbearance Agreements restrict the Company from: (i) repaying any principal amount owing to DSM
Finance B.V. under its loan agreement with the Company, (ii) incurring indebtedness other than certain permitted indebtedness under the 2019 LSA, 2022 LSA and Perrara LSA, and (iii) making investments or acquisitions subject to limited
exceptions permitted under the 2019 LSA, 2022 LSA and Perrara LSA.
In addition, the Forbearance Agreements provide certain rights to request reasonable
financial, operating and property related data and other information from the Company as well as information from any financial advisors to the Company relating its affairs, finances and businesses. In addition, the Company agreed to provide the
lenders with certain cash flow projections on a weekly basis.
