B. The Board of Directors is expressly empowered to adopt, amend or repeal the Bylaws of the corporation. The stockholders shall also have power to adopt, amend or repeal the Bylaws of the corporation; provided, however, that, in addition to any vote of the holders of any class or series of stock of the corporation required by law or by this Certificate of Incorporation, such action by stockholders shall require the affirmative vote of the holders of at least a majority of the voting power of all of the then-outstanding shares of the capital stock of the corporation entitled to vote generally in the election of directors, voting together as a single class.

VI.

A. In anticipation that Frazier Life Sciences X, L.P., and/or any affiliates (each, an “Investor”, and collectively, the “Investors”) will be, indirectly or directly, substantial stockholders of the Corporation, and in recognition of (i) the benefits to be derived by the Corporation through its continued contractual, corporate and business relations with each Investor (including service of officers, directors, partners, managers, employees or affiliates of each Investor (collectively, “Investor Persons”) as directors of the Corporation) and (ii) the difficulties attendant to any director, who desires and endeavors fully to satisfy such director’s fiduciary duties, in determining the full scope of such duties in any particular situation, the provisions of this Article VI are set forth to regulate, define and guide the conduct of certain affairs of the Corporation as they may involve the Investors and any Investor Persons, and the powers, rights, duties and liabilities of the Corporation and its offices, directors and stockholders in connection therewith.

B. Except as the Investors may other agree in writing, each Investor shall have the right to (i) engage, directly or indirectly, in the same or similar business activities or lines of business as the Corporation and (ii) do business with any client, competitor or customer of the Corporation, with the result that the Corporation shall have no right in or to such activities or any proceeds or benefits therefrom, and no Investor or Investor Person (except as provided in paragraph (c) of this Article VI), shall be liable to the Corporation or its stockholders for breach of any fiduciary duty by reason of any such activities of such Investor or such Investor Person’s participation there.

C. In the event that a director or officer of the Corporation who is an Investor Person acquires knowledge of a potential transaction or matter that may be a corporate opportunity for both the Corporation and any Investor, such corporate opportunity shall belong to such Investor, and the Corporation hereby renounces any interest or expectancy it may have in such corporate opportunity, unless such corporate opportunity is expressly offered to such director or officer in writing solely in his capacity as a director or officers of the Corporation, in which case such corporate opportunity shall belong to the Corporation.

D. For the purposes of this Article VI, “corporate opportunities” shall not include any business opportunities that the Corporation is not financially or contractually able to undertake, or that are, from their nature, not in the line of the Corporation’s business or are of no practical advantage to it or that are ones in which the Corporation has no interest or reasonable expectancy.

E. Any person or entity purchasing or otherwise acquiring any interest in any shares of capital stock of the Corporation shall be deemed to have notice of and consent to the provisions of this Article VI.

F. For purposes of this Article VI only, the “Corporation” shall mean MokshaCo, Inc. and all corporations, partnerships, joint ventures, associations and other entities in which the Corporation beneficially owns (directly or indirectly) fifty percent (50%) or more of the outstanding voting stock, voting power or similar voting interests.

VII.

The corporation elects not to be governed by Section 203 of the DGCL.

VIII.

A. The liability of the directors for monetary damages shall be eliminated to the fullest extent under applicable law. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

B. Any repeal or modification of this Article VIII shall be prospective and shall not affect the rights under this Article VIII in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification.

IX.

The corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon the stockholders herein are granted subject to this reservation.
