Now, Therefore, in consideration of the premises and the mutual covenants herein contained, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

Payment of the Purchase Price for the Shares shall be made against delivery to the Investor of the Shares, which Shares shall be uncertificated and shall be registered in the name of the Investor on the books of the Company by the Company’s transfer agent.

1.2Closing. The closing of the sale and purchase of the Shares (the “Closing”) will take place remotely via the exchange of documents and signatures after the satisfaction or waiver of each of the conditions set forth in Section 4 and Section 5 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) immediately following the IPO Closing Date.

2.Representations and Warranties of the Company. The Company hereby represents and warrants to the Investor that the following representations are true and correct as of the date hereof and as of the Closing (except to the extent any such representations and warranties expressly relate to an earlier date, in which case such representations and warranties are true and correct as of such earlier date).

2.1Organization, Valid Existence and Qualification. The Company is a corporation duly organized and validly existing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as currently conducted. The Company is duly qualified to transact business as a foreign corporation in each jurisdiction in which it conducts its business, except where failure to be so qualified could not reasonably be expected to result, either individually or in the aggregate, in a material adverse effect on the Company’s financial condition, business or operations.

2.2Registration Statement. The Registration Statement, as presently filed and when declared effective by the SEC, does not contain, and as amended or supplemented, if applicable, will not contain, as of the date of such amendment or supplement, any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading and complied (or, in the case of amendments filed after the date of this Agreement, will comply) as of its filing date in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder. “Registration Statement” means the registration statement on Form S-1, including any prospectus filed pursuant to Rule 424 under the Securities Act, and any free writing prospectuses, relating to the IPO.

2.3Authorization.

2.4Valid Issuance of Shares. The Shares that are being purchased by the Investor hereunder, when issued, sold and delivered in accordance with the terms of this Agreement for the consideration expressed herein, will be duly and validly issued, fully paid, and nonassessable, and will be transferred to

2

the Investor free of liens, encumbrances and restrictions on transfer other than (a) restrictions on transfer under this Agreement and under applicable state and federal securities laws, (b) restrictions on transfer under the Lock-Up Agreement (as defined below) and (c) any liens, encumbrances or restrictions on transfer that are created or imposed by the Investor. Subject in part to the truth and accuracy of the Investor’s representations set forth in Section 3 of this Agreement, the offer, sale and issuance of the Shares as contemplated by this Agreement are exempt from the registration requirements of applicable state and federal securities laws.

2.5Non-Contravention.

The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby will not result in any such violation or constitute, with or without the passage of time and giving of notice, either (i) a default in any material respect of any such instrument, judgment, order, writ or decree, or (ii) an event that results in the creation of any lien, charge or encumbrance upon any assets of the Company or the suspension, revocation, impairment, forfeiture, or nonrenewal of any material permit, license, authorization or approval applicable to the Company, in each case, which could reasonably be expected to result, either individually or in the aggregate, in a material adverse effect on the Company’s financial condition, business or operations.

2.6No Brokers. The Company has not incurred, and will not incur in connection with the sale of the Shares, any brokerage or finders’ fees, or agents’ commissions or similar liabilities.

3.Representations and Warranties of the Investor. The Investor hereby represents and warrants to the Company that the following representations are true and correct as of the date hereof and as of the Closing (except to the extent any such representations and warranties expressly relate to an earlier date, in which case such representations and warranties are true and correct as of such earlier date):

3.1Authorization. The Investor has all requisite power and authority to enter into this Agreement and this Agreement constitutes its valid and legally binding obligations, enforceable in accordance with its terms except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement of creditors’ rights generally, and (b) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

3.2Purchase Entirely for Own Account. This Agreement is made with the Investor in reliance upon the Investor’s representations to the Company, which by the Investor’s execution of this Agreement the Investor hereby confirms, that the Shares acquired by the Investor hereunder will be acquired for investment for the Investor’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Investor has no present intention of selling,

3

granting any participation in, or otherwise distributing the same, except as permitted by applicable federal or state securities laws. By executing this Agreement, the Investor further represents that the Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participation rights to such person or to any third person, with respect to any of the Shares.

3.3No Solicitation. At no time was the Investor presented with or solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Shares.

3.4Access to Information.

The Investor further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares. The foregoing, however, does not in any way limit or modify the representations and warranties made by the Company in Section 2.

3.5Investment Experience. The Investor understands that the purchase of the Shares involves substantial risk. The Investor has experience as an investor in securities of companies in the development stage and acknowledges that the Investor is able to fend for itself, can bear the economic risk of the Investor’s investment in the Shares, including a complete loss of the investment, and has such knowledge and experience in financial or business matters that the Investor is capable of evaluating the merits and risks of this investment in the Shares and protecting its own interests in connection with this investment.

3.6Accredited Investor or Qualified Institutional Buyer. The Investor understands the terms “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act and “qualified institutional buyer” as defined in Rule 144A under the Securities Act and is either an “accredited investor” or a “qualified institutional buyer” for the purposes of acquiring the Shares to be purchased by the Investor under this Agreement.

3.7Restricted Securities. The Investor understands that the Shares are characterized as “restricted securities” under the Securities Act inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under the Securities Act and applicable regulations thereunder such securities may be resold without registration under the Securities Act only in certain limited circumstances. The Investor represents that the Investor is familiar with Rule 144 of the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

3.8Legends. The Investor understands that the certificates or book-entry account evidencing the Shares may bear one or all of the following legends (or substantially similar legends):
