to: (a) sign any and all instruments, certificates and documents required to be executed on behalf of the Grantor as an individual (if applicable) or in the Grantor’s capacity as a general partner, manager, member, managing member or
authorized signatory, as the case may be, on behalf of any of the following (i) Canaan Partners, (ii) any of the funds or accounts managed, advised or sponsored by Canaan Partners (the “Canaan Funds”) and (iii) any of
the entities formed to act as the direct or indirect general partner, manager, managing member or equivalent of such funds or accounts (the “Canaan General Partners”, together with Canaan Partners and the Canaan Funds collectively,
the “Canaan Entities”), in each case, pursuant to the Securities Act of 1933, as amended, (the “Securities Act”), and any and all rules and regulations promulgated thereunder (including, without limitation, filings
pursuant to Rule 144 (Form 144)) or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any and all rules and regulations promulgated thereunder (including, without limitation, filings pursuant to
Section 16 (Forms 3, 4 and 5) and Section 13 (Schedule 13D, Schedule 13G, Form 13F and Form 13H) of the Exchange Act); and (b) file the same, with all exhibits thereto, and any other documents in connection therewith, with the
Securities and Exchange Commission, and with any other entity when and if such is mandated by the Securities Act, the Exchange Act or by the Financial Industry Regulatory Authority, granting unto such Attorney-In-Fact full power and authority to do and perform each and every act and thing requisite and necessary fully to all intents and purposes as the Grantor might or could do in person thereby, and
ratifying and confirming all that such Attorney-In-Fact, or his or her substitute or substitutes, may lawfully do or cause to be done by virtue hereof, or may have done
in connection with the matters described above. By this power of attorney, each Grantor hereby revokes all previous powers of attorney granted by him, her or it to any
Attorney-In-Fact or any other employee, representative or agent of Canaan Partners relating to the matters described above.
2. Effective Date and Termination. This power of attorney shall be effective as to each Grantor as of such Grantor’s
Effective Date and shall remain in full force and effect with respect to each Grantor and each Attorney-In-Fact until:
(a) in the case of any Grantor that is an individual, the earlier of the date on which this power of attorney is revoked in writing by such
Grantor solely as it relates to himself or herself and such Grantor’s Termination Date (as defined below);
(b) in the case of any
Grantor that is an entity, the earlier of the date on which this power of attorney is revoked in writing by such Grantor solely as it relates to itself and the filing by such entity of a certificate of cancellation or notice of dissolution with the
jurisdiction in which it was organized evidencing such entity’s complete dissolution and termination under the laws of such jurisdiction; and
(c) in the case of any Attorney-In-Fact, the earlier of the
date on which such person is no longer listed on Schedule A attached hereto as an “Attorney-In-Fact” or such Attorney-In-Fact’s Termination Date.
For purposes of the foregoing, “Termination Date”
means (i) with respect to any Grantor or Attorney-In-Fact that is a member or manager of any Canaan General Partner, the date on which such Grantor becomes a
“retired member” of any Canaan General Partner or, if later, the date on which his, her or its employment with Canaan Partners terminates for any reason and (ii) with respect to any other Grantor or Attorney-In-Fact, the date on which his, her or its employment with Canaan Partners terminates for any reason.
