Stock Award. Subject to the approval of the Board, you will be issued a stock award consisting of 95,480 shares of the Company’s Common Stock (the “Stock Award”) (this amount is equal to approximately 0.95% of the Company’s fully-diluted equity as of the date of issuance, assuming the purchase of an aggregate of $8,000,000 in the Company’s Series Seed Preferred Stock by BridgeBio at a purchase price of $1.3248 per share) at a purchase price per share equal to 100% of the fair market value of the Company’s Common Stock on the issuance date, as determined by the Board or the Compensation Committee, which determination and issuance dates shall occur as promptly as practicable following your acceptance of this offer.

Award Agreements. Each Award Agreement shall either be # in writing in a form approved by the Committee and executed by the Company by an officer duly authorized to act on its behalf, or # an electronic notice in a form approved by the Committee and recorded by the Company (or its designee) in an electronic recordkeeping system used for the purpose of tracking one or more types of Awards as the Committee may provide; in each case and if required by the Committee, the Award Agreement shall be executed or otherwise electronically accepted by the recipient of the Award in such form and manner as the Committee may require. The Committee may authorize any officer of the Company to execute any or all Award Agreements on behalf of the Company. The Award Agreement shall set forth the material terms and conditions of the Award as established by the Committee consistent with the provisions of the Plan.

Initial Award. Each individual who first becomes an Outside Director following the effective date of the Registration Statement (the “Registration Date”) and following the first annual meeting of the Company’s stockholders (an “Annual Meeting”) following the Registration Date will automatically be granted an Award (the “Initial Award”), which grant will be effective on the date on which such individual first becomes an Outside Director, whether through election by the stockholders of the Company or appointment by the Board to fill a vacancy. The Initial Award will have a Value (as defined below) of $175,000 multiplied by a fraction # the numerator of which is # 12 minus # the number of full months between the date of the last Annual Meeting and the date the Outside Director becomes a member of the Board and # the denominator of which is 12 (with the result rounded down to the nearest whole Share). For example, if nine months have lapsed between the last Annual Meeting and the Outside Director’s start date, his or her Initial Award will have a Value of $43,750. The Initial Award will be comprised solely of Restricted Stock Units.
