Ladies & Gentlemen:

The undersigned is an owner of shares of common stock, par value $0.0001 per share, of the Company (“Shares”) or of securities convertible into or exchangeable or exercisable for Shares. The Company proposes to conduct a private placement of Shares (the “Private Placement”) for which Morgan Stanley & Co. LLC (“Morgan Stanley”), Jefferies LLC (“Jefferies”), Piper Sandler & Co. (“Piper”) and LifeSci Capital LLC (“LifeSci”) will act as the placement agents (collectively, the “Placement Agents”). The undersigned recognizes that the Private Placement will benefit each of the Company and the undersigned. The undersigned acknowledges that the Placement Agents are relying on the representations and agreements of the undersigned contained in this letter agreement in conducting the Private Placement and other arrangements with the Company with respect to the Private Placement.

Annex A sets forth definitions for capitalized terms used in this letter agreement that are not defined in the body of this letter agreement. Those definitions are a part of this letter agreement.

In consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees that, during the Lock-up Period, the undersigned will not (and, if the undersigned is a natural person, will cause any Family Member not to), without the prior written consent of Morgan Stanley, Jefferies and Piper, which may withhold their consent in their sole discretion:

2

The foregoing will not apply to the offer and sale of the Shares, and the sale of the Shares pursuant to the Private Placement. In addition, the foregoing restrictions will not apply to the transfer of Shares or Related Securities:

3

provided, however, that in any such case, it shall be a condition to such transfer that:

Furthermore, notwithstanding the restrictions imposed by this letter agreement, the undersigned may establish a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Shares or Related Securities, provided that such plan does not provide for any transfers of Shares or Related Securities during the Lock-up Period and the entry into such plan is not publicly disclosed, including in any filing under the Exchange Act, during the Lock-up Period.

4

Moreover, notwithstanding the restrictions imposed by this letter agreement, the undersigned may    demand for, or exercise any right with respect to, the registration under the Securities Act of the offer and sale of any Shares or Related Securities held by the undersigned, or cause to be filed a registration statement, prospectus or prospectus supplement (or an amendment or supplement thereto) with respect to any such registration; provided, that (i) the Resale Registration Statement (as defined below) shall have first been filed and declared effective by the SEC and (ii) no Shares or Related Securities shall be sold under any such registration during the Lock-up Period.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Shares or Related Securities held by the undersigned and, if the undersigned is a natural person, the undersigned’s Family Members, if any, except in compliance with the foregoing restrictions.

With respect to the registration statement that is contemplated to be filed with the SEC by the Company to register the resale of the Shares to be sold in the Private Placement (the “Resale Registration Statement”) only, the undersigned waives any registration rights relating to registration under the Securities Act of the offer and sale of any Shares and/or any Related Securities owned either of record or beneficially by the undersigned, including any rights to receive notice of the Private Placement or the Resale Registration Statement.

The undersigned confirms that the undersigned has not, and has no knowledge that any Family Member

has, directly or indirectly, taken any action designed to or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale of the Shares. The undersigned will not, and will cause any Family Member not to take, directly or indirectly, any such action.

The undersigned acknowledges and agrees that the Placement Agents have not provided any recommendation or investment advice nor have the Placement Agents solicited any action from the undersigned with respect to the Private Placement and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Placement Agents may be required or choose to provide certain Regulation Best Interest and Form CRS disclosures to the undersigned in connection with the Private Placement and the Placement Agents are not making a recommendation to the undersigned to enter into this letter agreement and nothing set forth in such disclosures is intended to suggest that the Placement Agent is making such a recommendation.

Whether or not the Private Placement occurs as currently contemplated or at all depends on market conditions and other factors. The Private Placement will only be made pursuant to the Stock Purchase Agreement. Notwithstanding anything to the contrary contained herein, this letter agreement will automatically terminate and the undersigned shall be released from all obligations under this letter agreement upon the earliest to occur, if any, of (i) the Company advising the Placements Agents in writing prior to the Private Placement that it has determined not to proceed with the Private Placement or (ii) October 31, 2022, in the event the Private Placement has not been conducted by such date.

The undersigned hereby represents and warrants that the undersigned has full power, capacity and authority to enter into this letter agreement. This letter agreement is irrevocable and will be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This letter agreement may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or www.echosign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

This letter agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

2. Registration Rights.

2.1 Shelf Registration.

(a) Registration Statements. On or prior to November 1, 2022 (the “Filing Deadline”), the Company shall use commercially reasonable efforts to prepare and file with the SEC a Registration Statement on Form S-3 (or, if Form S-3 is not then available to the Company, on such form of registration statement as is then available to effect a registration for resale of the Registrable Securities), subject to the provisions of Section 2.1(c), for the resale of the Registrable Securities pursuant to an offering to be made on a continuous basis pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”). Such Shelf Registration Statement shall, subject to the limitations of Form S-3, include the aggregate amount of Registrable Securities to be registered therein and shall contain (except if otherwise required pursuant to written comments received from the SEC upon a review of such Shelf Registration Statement) the “Plan of Distribution” substantially in the form of Annex A (which may be modified to respond to comments, if any, provided by the SEC). To the extent the staff of the SEC does not permit all of the Registrable Securities to be registered on the Shelf Registration Statement filed pursuant to this Section 2.1(a) or for any other reason any Registrable Securities are not then included in a Registration Statement filed under this Agreement, the Company shall (i) inform each of the Participating Holders thereof and use its commercially reasonable efforts to file amendments to the Shelf Registration Statement as required by the SEC and/or (ii) withdraw the Shelf Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the SEC, on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to the filing such amendment or New Registration Statement, the Company shall use its commercially reasonable efforts to advocate with the SEC for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, the Manual of Publicly Available Telephone Interpretations D.29. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering, unless otherwise directed in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will be reduced on a pro rata basis based on the total number of unregistered Shares held by such Holders, subject to a determination by the SEC that certain Holders must be reduced first based on the number of Shares held by such Holders. In the event the Company amends the Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the SEC, as promptly as allowed by the SEC or SEC Guidance provided to the Company or to registrants of securities in general, one or more Registration Statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Shelf Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statement”). In no event shall any Participating Holder be identified as a statutory underwriter in the Registration Statement unless in response to a comment or request from the staff of the SEC or another regulatory agency; provided, however, that if the SEC requests that a Participating Holder be identified as a statutory underwriter in the Registration Statement, such Holder will have an opportunity to withdraw from the Registration Statement.

-4-

(b) Effectiveness.

(i) The Company shall use commercially reasonable efforts to have the Shelf Registration Statement or New Registration Statement declared effective as soon as practicable but in no event later than the Effectiveness Deadline (including filing with the SEC a request for acceleration of effectiveness in accordance with Rule 461 promulgated under the Securities Act), and shall use its commercially reasonable efforts to keep the Shelf Registration Statement or New Registration Statement continuously effective under the Securities Act until the earlier of (A) such time as all of the Registrable Securities covered by such Registration Statement have been publicly sold by the Holders, or (B) the date that all the Shares cease to be Registrable Securities (the “Effectiveness Period”); provided, that, the Company will not be obligated to update the Registration Statement and no sales may made under the applicable Registration Statement during any Allowed Delay of which the Holders have received notice. The Company shall notify the Participating Holders of the effectiveness of a Registration Statement by e-mail as promptly as practicable, and shall, if requested provide the Participating Holders with copies of the final Prospectus to be used in connection with the sale or other disposition of the securities covered thereby.

(ii) On not more than three occasions and for not more than forty-five (45) consecutive days or for a total of not more than ninety (90) days, in each case in any twelve (12) month period, the Company may suspend the use of any Prospectus included in any Registration Statement contemplated by this Section 2 if (A) the negotiation or consummation of a transaction by the Company is pending or an event has occurred, which negotiation, consummation or event, the Board reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Board, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (B) the Company determines in good faith, upon advice of legal counsel, that such suspension is necessary to amend or supplement the Registration Statement or the related Prospectus so that such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that the Company shall promptly (1) notify each Participating Holder in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of a Participating Holder) disclose to such Participating Holder any material non-public information giving rise to an Allowed Delay, (2) advise the Participating Holders in writing to cease all sales under such Registration Statement until the end of the Allowed Delay and (3) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.

(c) In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on another appropriate form reasonably acceptable to the Holders and (ii) undertake to register the Registrable Securities on Form S-3 promptly after such form is available; provided, that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC.

(d) If: (i) the initial Registration Statement is not filed with the SEC on or prior to the Filing Deadline, (ii) the initial Registration Statement or the New Registration Statement, as applicable, is not declared effective by the SEC (or otherwise does not become effective) for any reason on or prior to the Effectiveness Deadline, (iii) after its Effective Date, (A) such Registration Statement ceases for any reason (including without limitation by reason of a stop order, or the Company’s failure to update the Registration Statement), to remain continuously effective as to all Registrable Securities for which it is required to be effective, or (B) the Holders are not permitted to utilize the Prospectus therein to resell such Registrable Securities (other than during an Allowed Delay), (iv) an Allowed Delay applicable to a Required Registration Statement exceeds the length of the Allowed Delay, or (v) after the Filing Deadline, and only in the event a Registration Statement is not effective or available to sell all Registrable Securities, the Company fails to file with the SEC any required reports under Section 13 or 15(d) of the Exchange Act such that it is not in compliance with Rule 144(c)(1), as

-5-

a result of which the Holders who are not affiliates are unable to sell Registrable Securities without restriction under Rule 144 (any such failure or breach in clauses (i) through (v) above being referred to as an “Event,” and, for purposes of clauses (i), (ii), (iii) or (v), the date on which such Event occurs, or for purposes of clause (iv) the date on which such Allowed Delay is exceeded, being referred to as an “Event Date”), then in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as liquidated damages and not as a penalty (“Liquidated Damages”), equal to 1.0% of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement for any Registrable Securities held by such Holder on the Event Date. The parties agree that notwithstanding anything to the contrary herein or in the Purchase Agreement, no Liquidated Damages shall be payable (i) if as of the relevant Event Date, the Registrable Securities may be sold by the Holders without volume or manner of sale restrictions under Rule 144, as determined by counsel to the Company pursuant to a written opinion letter to such effect, addressed and reasonably acceptable to the Holder and the Company’s transfer agent, (ii) to a Holder causing an Event that relates to or is caused by any action or inaction taken by such Holder, (iii) to a Holder in the event it is unable to lawfully sell any of its Registrable Securities because of possession of material non-public information or (iv) with respect to any period after the expiration of the Effectiveness Period (it being understood that this clause shall not relieve the Company of any Liquidated Damages accruing prior to the expiration of the Effectiveness Period). If the Company fails to pay any Liquidated Damages pursuant to this Section 2.1(d) in full within ten (10) Business Days after the date payable, the Company will pay interest on the amount of Liquidated Damages then owing to the Holder at a rate of 0.5% per month on an annualized basis (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder, accruing daily from the date such Liquidated Damages are due until such amounts, plus all such interest thereon, are paid in full. The Company shall not be liable for Liquidated Damages under this Agreement as to any Registrable Securities which are not permitted by the Commission to be included in a Registration Statement due solely to SEC Guidance from the time that it is determined that such Registrable Securities are not permitted to be registered until such time as the provisions of this Agreement as to the Remainder Registration Statements required to be filed hereunder are triggered, in which case the provisions of this Section 2.1(d) shall once again apply, if applicable. In such case, the Liquidated Damages shall be calculated to only apply to the percentage of Registrable Securities which are permitted in accordance with SEC Guidance to be included in such Registration Statement. The Liquidated Damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a month prior to the cure of an Event, except in the case of the first Event Date. With respect to a Holder, the Effectiveness Deadline for a Registration Statement shall be extended without default or Liquidated Damages hereunder in the event that the Company’s failure to obtain the effectiveness of the Registration Statement on a timely basis results from the failure of such Holder to timely provide the Company with information requested by the Company and necessary to complete the Registration Statement in accordance with the requirements of the Securities Act (in which case the Effectiveness Deadline would be extended with respect to Registrable Securities held by such Holder). The parties agree that the maximum aggregate Liquidated Damages payable to a Holder of Registrable Securities under this Agreement shall be 5.0% of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement for the Registrable Securities then held by such Holder.

2.2 Expenses. The Company will pay all expenses associated with each Registration Statement, including filing and printing fees, the Company’s counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities laws and listing fees, but excluding discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold.

-6-

2.3 Company Obligations. The Company will use commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will:

(a) prepare the required Registration Statement including all exhibits and financial statements required under the Securities Act to be filed therewith, and provide copies to and permit each Participating Holder to review each Registration Statement and all amendments and supplements thereto prior to their filing with the SEC and a reasonable opportunity to furnish comments thereon (it being acknowledged and agreed that if a Participating Holder does not object to or comment on the aforementioned documents, then the Participating Holder shall be deemed to have consented to and approved the use of such documents);

(b) file with the SEC a Registration Statement relating to the Registrable Securities including all exhibits and financial statements required by the SEC to be filed therewith, and use commercially reasonable efforts to cause such Registration Statement to become effective under the Securities Act;

(d) (i) notify the Participating Holders by facsimile or e-mail as promptly as practicable after any Registration Statement is declared effective or any post-effective amendment to a Registration Statement is declared effective, and shall simultaneously provide the Participating Holders with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby (provided, that the Company will not have any obligation to provide any document pursuant to this clause that is available on the EDGAR system), (ii) promptly notify the Participating Holders no later than one (1) trading day following the date (A) of the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement covering any or all of the Registrable Securities or any order by the SEC preventing or suspending the use of any preliminary or final Prospectus or the initiation of any proceedings for such purposes, (B) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for offering or sale in any jurisdiction and (C) of the receipt by the Company of any notification with respect to the initiation or threatening of any proceeding for the suspension of the qualification of the Registrable Securities for offering or sale in any jurisdiction;

(h) on or prior to the date on which the Registration Statement is declared effective, use its commercially reasonable efforts to register or qualify, or cooperate with the Participating Holders and their respective counsel, in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for offer and sale under the applicable state securities or “Blue Sky” laws of those jurisdictions within the United States as any Participating Holder or their respective counsel reasonably request in writing and do any and all other acts or things reasonably necessary or advisable to keep such registration or qualification (or exemption therefrom) in effect during the Effectiveness Period, provided that the Company shall not be required to qualify generally to do business or as a dealer in securities in any jurisdiction where it is not then so qualified or to take any action which would subject it to taxation or general service of process in any such jurisdiction where it is not then so subject;

2.4 Obligations of the Purchasers.

(a) Notwithstanding any other provision of the Agreement, no Holder of Registrable Securities may include any of its Registrable Securities in the Registration Statement pursuant to this Agreement unless the Holder furnishes to the Company a completed and signed selling stockholder questionnaire in customary form that contains such information regarding Purchaser, the securities of the Company held by Purchaser and the intended method of disposition of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, at least ten (10) Business Days prior to the first anticipated filing date of any Registration Statement if such Purchaser elects to have any of its Registrable Securities included in the Registration Statement. Each Holder who intends to include any of its Registrable Securities in the Registration Statement shall promptly furnish the Company in writing such other information as the Company may reasonably request in writing. Each Holder acknowledges and agrees that the information in the selling shareholder questionnaire or request for further information as described in this Section 2.4(a) will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement. The Company shall not be obligated to file more than one post-effective amendment or supplement in any sixty (60) day period following the date such Registration Statement is declared effective for the purposes of naming Holders as selling security holders who are not named in such Registration Statement at the time of effectiveness.

(b) Each Purchaser, by its acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Purchaser has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement. The Company may require each selling Holder to furnish to the Company a certified statement as to (i) the number of shares of Common Stock beneficially owned by such Holder and any affiliate thereof, (ii) any FINRA affiliations, (iii) any natural persons who have the power to vote or dispose of the Common Stock and (iv) any other information as may be requested by the SEC, FINRA or any state securities commission. Each Holder agrees by its acquisition of such Registrable Securities that, it will not commence a disposition of Registrable Securities under the Registration Statement until such Holder has received (i) written confirmation from the Company of the availability of the Registration Statement, or (ii) copies of the supplemented Prospectus and/or amended Registration Statement as described, and, in each case, has also received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement.

-9-

(c) Each Purchaser agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to Section 2.1(b) or (ii) the happening of any event of the kind described in Section 2.3(d) and Section 2.3(e) hereof, such Purchaser will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until the Purchaser is advised by the Company that such dispositions may again be made and/or the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed and, if so directed by the Company, each Holder will deliver to the Company or destroy (at the Company’s expense) all copies, other than permanent file copies then in its possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice.

2.5 Indemnification.

(a) Indemnification by the Company. The Company will indemnify and hold harmless each Participating Holder who sells Registrable Securities covered by such Registration Statement and its officers, directors, members, employees, investment advisers and agents, successors and assigns, and each other person, if any, who controls such Participating Holder within the meaning of the Securities Act, against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) (collectively, “Losses”), actually incurred, joint or several, to which they may become subject under the Securities Act or otherwise, insofar as such Losses (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof or arising out of or relating to any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading; or (ii) any violation by the Company or its agents of any rule or regulation promulgated under the Securities Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; and will reimburse such Participating Holder who sells Registrable Securities covered by such Registration Statement, and each such officer, director, employee, agent or member and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or action; provided, however, that the Company will not be liable in any such case to the extent that any such Losses arise out of or are based upon (x) an untrue statement or alleged untrue statement or omission or alleged omission so made in reliance upon or in conformity with information furnished by such Purchaser or any such controlling person in writing specifically for use in such Registration Statement or Prospectus (preliminary, final or summary) or any amendment or supplement thereto or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being understood that each Holder has approved Annex A hereto for this purpose), (y) the use by a Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that such Prospectus is outdated or defective or (z) a Purchaser’s (or any other indemnified Person’s) failure to send or give a copy of the Prospectus or supplement (as then amended or supplemented), if required, pursuant to Rule 172 under the Securities Act (or any successor rule) to the Persons asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person if such statement or omission was corrected in such Prospectus or supplement.

-10-

(b) Indemnification by the Participating Holders. Each Purchaser agrees, severally but not jointly with any other Purchaser, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders, agents, and each person who controls the Company (within the meaning of the Securities Act and the Exchange Act) against any Losses (i) arising out of, based on, or resulting from any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be stated in any Registration Statement or Prospectus (preliminary, final or summary) or any amendment or supplement thereto or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, to the extent, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any information furnished in writing by such Purchaser to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto, or a document incorporated by reference into any of the foregoing; or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly for use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (ii) related to the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating to this Section 2.5 and the amount of any damages such Holder has otherwise been required to pay by reason of such untrue statement or omission) received by such Holder upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party (provided, however, that such indemnified party shall, at the expense of the indemnified party, be entitled to counsel of its own choosing to monitor such defense); provided that, subject to the preceding sentence, any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (A) the indemnifying party has agreed to pay such fees or expenses, or (B) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (C) in the reasonable judgment of any such Person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party, or any officer, director, employee, agent, affiliate, or controlling person of such indemnified party and shall survive the transfer of the Shares.

-11-

(d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No Person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any Person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a Holder be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating to this Section 2.5 and the amount of any damages such Holder has otherwise been required to pay by reason of such untrue statement or omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

Annex A

PLAN OF DISTRIBUTION

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended (the “Securities Act”), amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling stockholders for purposes of this prospectus.

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may

Annex A

also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or another available exemption from the registration requirements of the Securities Act.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934, as amended, may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling stockholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part to become effective and to remain continuously effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with such registration statement or (2) the date that all the shares covered by this prospectus cease to be Registrable Securities.

VENTYX BIOSCIENCES ANNOUNCES $176.6 MILLION PRIVATE PLACEMENT OF COMMON STOCK

SEPTEMBER 19, 2022

ENCINITAS, Calif., Sept. 19, 2022 (GLOBE NEWSWIRE) — Ventyx Biosciences, Inc.

Gross proceeds of the private placement are expected to be approximately $176.6 million, before deducting placement agent fees and other expenses. The private placement is expected to close on September 20, 2022, subject to the satisfaction of customary closing conditions.

The private placement was led by Redmile Group, with participation by Boxer Capital, Braidwell LP, EcoR1 Capital, Vivo Capital, Great Point Partners, LLC, Adage Capital Management, Logos Capital, Maven Investment Partners US, Acuta Capital Partners, CaaS Capital Management, Driehaus Capital Management, Woodline Partners LP and Walleye Capital and other investors, including two large mutual funds.

With the proceeds from the private placement, Ventyx expects to extend its cash runway into 2025. This cash estimate is a preliminary estimate and is based on information available to management as of the date of this private placement, and these estimates could change.

Morgan Stanley, Jefferies, Piper Sandler and LifeSci Capital are acting as the placement agents for the private placement.

The securities being issued and sold in the private placement have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any states’ securities laws, and may not be offered or sold in the United States, except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act. Ventyx has agreed to file a registration statement with the Securities and Exchange Commission registering the resale of the shares of common stock issued in this private placement.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy any securities described herein, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
