CONVERTIBLE INVESTMENT INSTRUMENT AGREEMENT

This Convertible Investment Instrument Agreement (“Agreement”) is dated as of December 21, 2021 by and among GreenLight Biosciences, Inc., a Delaware corporation (the “Company”) and the individuals and entities who become parties to this Agreement by executing and delivering an Agreement Signature Page in the form of Exhibit A hereto in accordance with Section 2 hereof (each a “Purchaser” and, collectively, the “Purchasers”).

In consideration of the mutual promises and covenants contained in this Agreement, the parties hereto agree as follows:

1.        Authorization; Sale of Convertible Instruments

1.1.     Authorization. The Company has duly authorized the sale and issuance, pursuant to the terms of this Agreement, at one or more closings, of Convertible Instruments in the form attached hereto as Exhibit B in the aggregate principal amount of up to $5,000,000.00 (each an “Instrument” and, collectively, the “Instruments”).

1.2.     Use of Proceeds. The Company will use the proceeds from the sale of the Instruments for working capital and other general corporate purposes.

2.        Closings. Subject to the terms and conditions of this Agreement, each closing (a “Closing” and, collectively, the “Closings”) of the sale and purchase of Instruments under this Agreement shall take place at Foley Hoag LLP, Seaport West, 155 Seaport Boulevard, Boston, MA 02210-2600 (or remotely via the exchange of documents and signatures) (the date of each such Closing, a “Closing Date”). At each Closing, the Company shall deliver an Instrument to each Purchaser participating in such Closing in the original principal amount set forth next to such Purchaser’s name on such Purchaser’s signature page hereto, and each Purchaser shall pay to the Company via check or wire transfer the purchase price therefor, which shall be equal to such original principal amount.

3.         Certain Terms of the Instruments.

3.1.     Maturity. Each Instrument shall be due and payable on demand by holders of Instruments representing a majority of the aggregate principal amount then outstanding under all of the Instruments (such holders, the “Required Holders”) upon the earlier of (i) twelve (12) months from the date hereof (the “Maturity Date”), or (ii) the occurrence of an Event of Default (as defined below).

3.2.     Interest. The principal balance of the Instruments shall bear interest at a rate of the minimum applicable federal rate per annum payable at maturity.

3.3.     Payments. Any payments on the Instruments shall be made in proportion to the outstanding principal amount and accrued but unpaid interest on each such Instrument represents relative to the aggregate outstanding principal amount and accrued but unpaid interest of all Instruments. The Company may prepay the Instruments in whole or in part at any time. Any prepayment of principal shall be accompanied by any interest accrued thereon.

3.4.     Conversion.

(a)     Upon a Qualified Financing. For the purposes of this Agreement, a “Qualified Financing” shall mean an equity financing involving the sale of capital stock of the Company primarily for capital-raising purposes on terms no less favorable to the Purchasers than the terms of the Series D Preferred Stock, $.001 par value per share, of the Company. Upon the closing of such Qualified Financing, all then outstanding principal on each Instrument shall automatically convert into that number of shares of capital stock issued in such Qualified Financing (the “Qualified Financing Securities”) equal to the quotient obtained by dividing (i) the outstanding principal amount of such Instrument by (ii) the lower of (x) the Conversion Discount Price (as defined below), or (y) the Capped Price (as defined below). All accrued interest on the Instruments shall be payable in cash. Each Purchaser agrees that, in connection with the conversion of the Instruments at a Qualified Financing in accordance with this Section 3.4(a), such Purchaser will execute all necessary documents in connection with such Qualified Financing reasonably requested of the Purchasers, including executing a definitive purchase agreement, investor rights agreement and such other financing agreements as shall be agreed upon by the Company and the other investors participating in such Qualified Financing.

(b)     Upon a Sale of the Company or IPO. The Company shall notify the holders of outstanding Instruments of (i) the closing of a Change of Control (as defined below) at least five (5) days prior to the expected closing of such Change of Control, or (ii) the consummation of an initial public offering (an “IPO”, and together with Change of Control, a “Trigger Event”) at least thirty (30) days prior to the expected effective date of the consummation of the IPO. Such notice shall include any information generally provided by the Company to the holders of the common stock, par value $0.001 per share, of the Company (the “Common Stock”) in connection with such Trigger Event, if any. Upon a Trigger Event, each Purchaser shall be entitled to receive in respect of such Purchaser’s Instrument(s), in preference to the holders of Common Stock, an amount equal to the outstanding principal of and interest on such Purchaser’s Instrument(s). “Change of Control” shall mean any sale, conveyance, or other disposition of all or substantially all of the Company’s assets or a merger of the Company with or into, or consolidation with, any other entity (other than a wholly-owned subsidiary of the Company), or any other transaction or series of related transactions, as a result of which less than fifty percent (50%) of the voting power of the surviving entity (or, if the surviving entity is a wholly-owned subsidiary of another entity, the ultimate parent of the surviving entity) is held by persons that are stockholders of the Company as of immediately prior to such event; provided, however, that a merger effected exclusively for the purpose of changing the domicile of the Company shall not be deemed to be a Change of Control; and provided, further, that the term “Change of Control” shall not apply to equity financings primarily for capital-raising purposes.

(c)     Effect of Conversion, Etc. Upon conversion of any Instrument pursuant to this Section 3, the Company will be forever released and discharged from all of its obligations and liabilities under such Instrument, including without limitation the obligation to pay the principal amount and accrued interest. No fractional shares shall be issuable by the Company upon conversion of any Instrument. In lieu of any fractional share which would otherwise be issuable upon conversion of any Instrument, the Company shall pay to the holder of such Instrument an amount in cash equal to the product of such fraction multiplied by the applicable conversion price. Upon conversion of each Instrument, the holder thereof shall surrender such Instrument, duly

Page 2

endorsed, at the principal offices of the Company or to any transfer agent of the Company. Following such surrender, the Company will, at its expense, issue and deliver to such holder a certificate or certificates for the securities to which such holder is entitled as a result of such conversion and a check payable to such holder for any cash amounts payable in lieu of any fractional share in accordance with this Section 3.4(c).

3.5.     Events of Default. Each of the following shall constitute an “Event of Default,” unless waived by the Required Holders:

(a)     the failure by the Company to pay any amount due hereunder within ten (10) days of the due date thereof;

(b)     the appointment of a receiver of any property, the assignment or trust mortgage for the benefit of creditors, the commencement of any kind of insolvency proceedings under any bankruptcy or other law relating to the relief of debtors, or the entry of an order for relief with respect to the Company in any proceeding pursuant to the United States Bankruptcy Code, as amended; or

(c)     the Company defaults in the payment of principal or interest due and owing under any other indebtedness agreement beyond any period of grace provided with respect thereto or in the performance or observance of any other agreement, term or condition contained in any agreement under which such obligation is created, if the effect of such default is that an amount in excess of $3 million is then due and allows for the acceleration of the maturity of such indebtedness or to permit the holder thereof to cause such indebtedness to become due prior to its stated maturity. Immediately upon the occurrence and during the continuance of an Event of Default described in this clause (c), the Company shall provide notice to Investor of such Event of Default.

3.6.     Redemption from Unaccredited Investors, Bad Actors. If at any time the Company shall determine, in its sole discretion, that any holder of a Instrument: (i) did not or does not qualify as an “accredited investor,” as such term is defined in Rule 501(a) of Regulation D (or any successor provision or amendment thereto) promulgated under the Securities Act of 1933, as amended (the “Securities Act”) (an “Accredited Investor”); or (ii) was or has become (or that any of such holder’s affiliates or other related parties was or has become) a “bad actor” within the meaning of Rule 506(d) promulgated under the Securities Act (“Rule 506(d)”), the Company may, at its sole election, redeem any Instrument held by such holder at any time without the consent of the holder thereof for an amount equal to the outstanding principal plus any accrued but unpaid interest thereon. Each holder of an Instrument redeemed pursuant to this Section 3.6 because such holder cannot certify to the Company that: (i) such holder is an Accredited Investor; or (ii) such holder is not a “bad actor,” as defined in Rule 506(d) (or that none of such holder’s affiliates or related parties are “bad actors”), acknowledges that: (a) such holder is not eligible to acquire securities in a Qualified Financing; (b) such holder therefore has no right to receive securities in exchange for its Instrument; and (c) that payment for the redemption of such Instrument can occur after the closing of a Qualified Financing from the proceeds of such Qualified Financing.

Page 3

3.7.     Definitions. For purposes of this Section 3:

(a)     “Conversion Discount Price” shall mean, with respect to any Qualified Financing, the per share price at which shares of Qualified Financing Securities are to be sold generally in such Qualified Financing (not including any discounts applicable as a result of the Instruments or any other convertible Instruments of the Company outstanding as of prior to such Qualified Financing) multiplied by 0.80.

(b)     “Capped Price” shall mean, with respect to any Qualified Financing, the per share price implied by a fully-diluted, pre-money valuation of the Company of $1,200,000,000 (which valuation includes any increase to the option pool made prior to or at the time of such Qualified Financing and all other rights to acquire capital stock of the Company outstanding at the time of such Qualified Financing (other than the Notes and any other convertible notes of the Company outstanding as of prior to such Qualified Financing)).

5.2.     Brokers and Finders. The Purchaser has not retained any investment banker, broker, or finder in connection with the transactions contemplated by this Agreement.

5.3.     Investment. The Purchaser is acquiring the Instrument as well as any shares of the Qualified Financing Securities or Common Stock issuable upon conversion thereof (collectively, the “Securities”) for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the sale or distribution of any part thereof. The Purchaser has no present intention of selling, granting any participation in, or otherwise distributing any Securities.

The Purchaser has not relied upon any representation or warranty by the Company or its representatives in connection with the transactions contemplated hereby other than those set forth in this Agreement.

5.9.     “Bad Actor” Disqualification. The Purchaser hereby represents that neither it nor any of its affiliates or other related parties is a “bad actor,” as defined in Rule 506(d).

The Purchaser’s subscription and payment for and continued beneficial ownership of the Securities or any subsequent issuance of equity securities pursuant to such ownership will not violate any applicable securities or other laws of the Purchaser’s jurisdiction.Anti-Money Laundering.
