(“Xxxxx Xxxxxxx”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 13 hereof), for whom Jefferies, SVB Securities and Xxxxx Xxxxxxx are acting as representatives (in such capacity, the “Representatives”), with respect to the issuance and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of registered ordinary shares (collectively, the “Securities”), nominal value CHF 0.05 per share, of the Company (“Ordinary Shares”) set forth in Schedule A hereto .

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form F-3 (No. 333-264653) covering the public offering and sale of certain securities, including the Securities, under the Securities Act of 1933, as amended (the “1933 Act”), which registration statement became effective on May 12, 2022. Such registration statement, as of any time, means such registration statement as amended by any post-effective amendments thereto to such time, including the exhibits and any schedules thereto at such time, the documents incorporated by reference therein at such time pursuant to Item 6 of Form F-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B (“Rule 430B”) under the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”), is referred to herein as the “Registration Statement;” provided, however, that the “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of such registration statement with respect to the Securities within the meaning of paragraph (f)(2) of Rule 430B, including the exhibits and schedules thereto as of such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 6 of Form F-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to the Rule 430B. Where no preliminary prospectus supplement is filed and distributed to investors in connection with the offering, the “preliminary prospectus” shall be deemed to be the prospectus included in the Registration Statement (and including any documents incorporated therein by reference) as such has been filed with the Commission at the Applicable Time. Promptly after execution and delivery of this Agreement, the Company will prepare and file a final prospectus supplement relating to the Securities in accordance with the provisions of Rule 424(b) (“Rule 424(b)”) of the 1933 Act Regulations. The final prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 6 of Form F-3 under the 1933 Act, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system or any successor system (“XXXXX”).

(ii) Accurate Disclosure. Neither the Registration Statement nor any amendment thereto, at its effective time, on the date hereof, at the Closing Time, contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At the Applicable Time, none of (A) the General Disclosure Package, (B) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package and (C) and individual Written Testing-the-Waters Communication, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Neither the Prospectus nor any amendment or supplement thereto, as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b), at the Closing Time, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, at the time the Registration Statement became effective or when such documents incorporated by reference were filed with the Commission, as the case may be, when read together with the other information in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, did not and will 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 not misleading.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any amendment thereto), the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the second and third paragraphs under the heading “Underwriting – Price Stabilization, Short Positions and Penalty Bids” contained in the Prospectus (collectively, the “Underwriter Information”).

(iii) Issuer Free Writing Prospectuses. No Issuer Free Writing Prospectus conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated or deemed to be incorporated by reference therein, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified.

(iv) Testing-the-Waters Materials. The Company (A) has not engaged in any Testing-the-Waters Communication other than Testing-the-Waters Communications with the consent of the Representatives with entities that are qualified institutional buyers within the meaning of Rule 144A under the 1933 Act or institutions that are accredited investors within the meaning of Rule 501 under the 1933 Act and (B) has not authorized anyone other than the Representatives to engage in Testing-the-Waters Communications.

(v) Company Not Ineligible Issuer.

No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 8 or Section 9 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonably incurred fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 8(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 9, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the number of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 10. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its Subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, or the Company, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 11. Termination of Agreement.

(a) Termination. The Representatives acting on behalf of the several Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time, as the case may be (i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is so material and adverse as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq Global Market, or (iv) if trading generally on or the NYSE MKT or the New York Stock Exchange or in the Nasdaq Global Select Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 6 hereof, and provided further that Sections 1, 8, 9, 10, 17, 18, 19, and 20 shall survive such termination and remain in full force and effect.

SECTION 12. [Reserved].

SECTION 13. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the (i) Representatives or (ii) the Company shall have the right to postpone Closing Time, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 13.

SECTION 14. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to Jefferies at 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: General Counsel, SVB Securities at 0000 0xx Xxxxxx, 00^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, attention of Xxxxxx Xxxxxx (facsimile: (000) 000-0000) or Xxxxx Xxxxxxx at 1251 Avenue of the Americas, 0xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: General Counsel. Notices to the Company shall be directed to the Company at Xxxxxxxxxxxxxxx 00, 0000 Xxxxx, Xxxxxxxxxxx, attention of Xxxxxxx X’Xxxxxxx, Chief Financial Officer (e-mail: [***]).

SECTION 15. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the initial public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its Subsidiaries or their respective shareholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Securities or the process leading thereto (irrespective of whether such

Underwriter has advised or is currently advising the Company or any of its Subsidiaries on other matters) and no Underwriter has any obligation to the Company with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 16. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section 16, a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

SECTION 17. Parties. This Agreement shall each inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 8 and 9 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 18. Trial by Jury. The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its affiliates) and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 19. GOVERNING LAW. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

SECTION 20. Consent to Jurisdiction; Waiver of Immunity; Judgment Currency; Foreign Taxes.

(a) Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding.

(b) Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints VectivBio US, Inc., at 00 Xxxxx Xx. Xxxxx 0000, Xxx Xxxx, Xxx Xxxx 00000, as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York.

(c) With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

(d) The Company agrees to indemnify each Underwriter, its directors, officers, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “judgment currency”) other than U.S. dollars and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order, and (ii) the rate of exchange at which such indemnified person is able to purchase U.S. dollars with the amount of the judgment currency actually received by the indemnified person. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

(e) Unless required by applicable law, all payments by the Company to the Underwriters hereunder shall be made free and clear of, and without deduction or withholding for or on account of, any and all present and future stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereinafter imposed, levied, collected, withheld or assessed by any jurisdiction in which the Company is organized, resident, doing business or has an office or from which payment is made, excluding any such tax imposed by reason of any Underwriter having some connection with the taxing jurisdiction other than its participation as an Underwriter hereunder (all such non-excluded taxes, including, VAT, “Foreign Taxes”). For the avoidance of doubt, all amounts payable by the Company under this Agreement shall be exclusive of VAT, and if any VAT is or becomes chargeable in respect of the supply to which such payment relates and the relevant recipient is required to account to the relevant tax authority for such VAT, the Company shall, upon receipt of a valid VAT invoice in respect of the supply to which that payment relates, pay at the same time and in the same manner as the payment to which such VAT relates, an amount equal to such VAT. If the Company is required to deduct or withhold Foreign Taxes or is prevented by operation of law or otherwise from paying, causing to be paid or remitting that portion of amounts payable hereunder represented by Foreign Taxes withheld or deducted, then amounts payable under this Agreement shall, to the extent permitted by law, be increased to such amount as is necessary to yield and remit to such Underwriters an amount which, after deduction of all Foreign Taxes (including all Foreign Taxes payable on such increased payments) equals the amount that would have been payable if no Foreign Taxes applied. By way of exception to the foregoing, a payment by the Company to an Underwriter shall not be increased by reason of a deduction or withholding on account of a tax imposed by Switzerland when the relevant Underwriter resides in a jurisdiction that has not entered into a double taxation agreement with Switzerland. In the event that an Underwriter has received and utilized a tax credit in respect of any amount withheld or deducted pursuant to this paragraph, such Underwriter shall pay to the Company as promptly as commercially practicable an amount which will leave the Underwriter (after that payment) in the same after-tax position as it would have been if no such deduction or withholding had been required to be made, it being understood that the foregoing does not require any Underwriter to investigate or claim any credit or refund that may be available to it or create any obligation to disclose any information relating to tax matters or any computation or return in respect thereof (other than the fact of the receipt and utilization of any such tax credit, which may be disclosed upon payment of the amount owed to the Company in respect thereof as provided above). Where this Agreement requires any person to reimburse or indemnify another person for any costs, expenses, fees or other amounts to which a reimbursement or indemnity relates, that first person shall reimburse or indemnify (as the case may be) the second person for the full amount of such cost or expense, including such part thereof as represents VAT (including any VAT incurred thereon which, for the avoidance of doubt, shall include any VAT on services provided from legal counsel where any Underwriter is required to self-assess and account for VAT in its role as the recipient of such services), save to the extent that the second person reasonably determines that it is entitled to credit or repayment in respect of such VAT from the relevant tax authority.

SECTION 21. TIME. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 22. Counterparts and Electronic Signatures. Counterparts and Electronic Signatures. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. Electronic signatures complying with the New York Electronic Signatures and Records Act (N.Y. State Tech. §§ 301-309), as amended from time to time, or other applicable law will be deemed original signatures for purposes of this Agreement. Transmission by telecopy, electronic mail or other transmission method of an executed counterpart of this Agreement will constitute due and sufficient delivery of such counterpart.

SECTION 23. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters and the Company in accordance with its terms.

Re:

Proposed Public Offering by VectivBio Holding AG

Dear Sirs:

The undersigned, understands that Xxxxxxxxx LLC (“Jefferies”), SVB Securities LLC (“SVB Securities”) and Xxxxx Xxxxxxx & Co. (“Xxxxx Xxxxxxx”), as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with VectivBio Holding AG, a Swiss stock corporation (Aktiengesellschaft) (the “Company”), providing for the public offering (the “Public Offering”) of the Company’s ordinary shares, nominal value CHF 0.05 per share (the “Ordinary Shares”). In recognition of the benefit that such an offering will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, during the period beginning on the date hereof and ending on the date that is 90 days from the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of the Representatives, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any Ordinary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-Up Securities, or file or cause to be filed any registration statement in connection therewith, under the Securities Act of 1933, as amended (the “Securities Act”), or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Ordinary Shares or other securities, in cash or otherwise. If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Lock-Up Securities the undersigned may purchase in the Public Offering.

Notwithstanding the foregoing, and subject to the conditions below, the foregoing restrictions shall not apply to, and the undersigned may transfer the Lock-Up Securities without the prior written consent of the Representatives, provided that (1) with respect to clauses (i), (ii), (iii) and (v) below, the Representatives receive a signed lock-up agreement for the balance of the Lock-Up Period from each donee, trustee, distributee, or transferee, as the case may be, and any such transfer shall not involve a disposition for value and (2) (A) in the case of clauses (i), (ii), (iii) and (v) and below, such transfers are not required to be reported, and no such reports are otherwise voluntarily made, during the Lock-Up Period with the Securities and Exchange Commission (the “Commission”) on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise, and (B) in the case of clauses (iv), (vi) and (vii), any such required Form 4 shall state the reason for such transfer in the footnotes thereto, and (3) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers:

(i)

as a bona fide gift or gifts, or for bona fide estate planning purposes; or

(ii)

to any member of the undersigned’s immediate family or to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this clause (ii) of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage, domestic partnership or adoption, not more remote than first cousin) or to any company wholly-owned by the undersigned or wholly-owned by one or more companies which are wholly-owned by the undersigned; or

(iii)

by will or intestate succession upon the death of the undersigned; or

(iv)

by operation of law or by order of a court of competent jurisdiction, such as pursuant to a court or regulatory agency order, a settlement agreement, a domestic order or in connection with a divorce settlement; or

(v)

if the undersigned is a corporation, partnership, limited liability company, trust or other business entity, to (x) another corporation, partnership, limited liability company, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act) of the undersigned, (y) any investment fund or other entity controlling, controlled by, managing, managed by or under common control with the undersigned or affiliates of the undersigned, or (z) as distributions to any limited partners, general partners, members, managers, managing members, shareholders or other equity holders of the undersigned or of the entities described in the preceding clauses (x) and (y); or

(vi)

to the Company (x) in connection with the exercise, vesting or settlement of equity awards on a “net” or “cashless” exercise basis to the extent permitted by the instruments representing such equity awards (including any transfer to the Company necessary to generate such amount of cash needed for the payment of taxes and social security contributions due or payment of the exercise price as a result of such exercise, vesting or settlement) so long as such “net” or “cashless” exercise is effected solely by the surrender of outstanding equity awards (or the Ordinary Shares issuable upon the exercise thereof) to the Company and the Company’s cancellation of all or a portion thereof to pay the exercise price and/or taxes and social security contributions and remittance obligations, in each case pursuant to an equity incentive plan described in the final prospectus relating to the Public Offering, or (y) pursuant to any contractual arrangement (A) disclosed in the

final prospectus relating to the Public Offering that provides the Company with an option to repurchase such Ordinary Shares in connection with the termination of the undersigned’s employment or other service relationship with the Company, (B) pursuant to a Special Mandatory Conversion as such term is defined in the Investment Agreement related to the series A2 financing or (C) that provides the Company with an option to repurchase Ordinary Shares in connection with the termination of the undersigned’s employment or other service relationship with the Company or in connection with the second tranche of the Company’s series A2 financing at a price that is below the fair market value of such Ordinary Shares, provided that, any Ordinary Shares received and not surrendered by the undersigned upon such exercise, vesting or settlement shall remain subject to the restrictions set forth herein; or

(vii)

to exercise equity awards pursuant to an equity incentive plan described in the final prospectus relating to the Public Offering and outstanding as of the date of the Underwriting Agreement, provided that any Ordinary Shares received by the undersigned upon such exercise shall remain subject to the restrictions set forth herein; or

(viii)

the disposition of Ordinary Shares to the Company, or the withholding of Ordinary Shares by the Company, in a transaction exempt from Section 16(b) of the Exchange Act solely in connection with the payment of taxes and social security contributions due with respect to the vesting of restricted shares granted under any equity incentive plan of the Company or pursuant to a contractual arrangement described in the final prospectus relating to the Public Offering, insofar as such restricted shares are outstanding as of the date of the Underwriting Agreement; or

pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction in each case made to all holders of Ordinary Shares, involving a Change of Control (as defined below), or the provision of an irrevocable undertaking to accept such tender offer, merger, consolidation or other similar transaction, provided that (x) in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Lock-Up Securities shall remain subject to the terms of this lock-up agreement and (y) no such transfer of Lock-Up Securities shall be permitted pursuant to this clause if such bona fide third-party tender offer, merger, consolidated or other similar transaction is not recommended by the board of directors of the Company, unless either (A) such transfer is required pursuant to mandatory take-over or squeeze-out provisions under Swiss law or (B) the failure to so transfer such Lock-Up Securities would result in such Lock-Up Securities being extinguished without value being received by the undersigned. “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than an underwriter pursuant to the Public Offering), of the Company’s voting securities if, after such transfer, such person or group of affiliated persons would hold more than 50% of the outstanding voting securities of the Company (or the surviving entity).

Furthermore, the undersigned may sell or transfer Ordinary Shares purchased by the undersigned in the Public Offering (other than any Company-directed Ordinary Shares acquired by an officer or director of the Company) or on the open market following the Public Offering if and only if (i) such sales or transfers are not required to be reported, and no such reports are otherwise voluntarily made, in any public report or filing with the Commission, or otherwise, and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales.

Furthermore, notwithstanding the foregoing, the restrictions in this lock-up agreement shall not apply to the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of the undersigned’s Ordinary Shares, provided that (i) no direct or indirect offers, pledges, sales, contracts to sell, sales of any option or contract to purchase, purchases of any option or contract to sell, grants of any option, right or warrant to purchase, loans, or other transfers or disposals of any of the undersigned’s Ordinary Shares may be effected pursuant to such plan during the Lock-Up Period and (ii) no public disclosure of the entry into such a trading plan shall be required or shall be voluntarily made by any person until after the expiration of 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 the Lock-Up Securities except in compliance with the foregoing restrictions.

The undersigned acknowledges and agrees that the underwriters have not provided any recommendation or investment advice nor have the underwriters solicited any action from the undersigned with respect to the offering of the securities and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate.

The undersigned understands that, if (1) either the Representatives, on the one hand, or the Company, on the other hand, informs the other, prior to the execution of the Underwriting Agreement, that they have determined not to proceed with the Public Offering, (2) the Underwriting Agreement is not duly executed by November 30, 2022, or (3) the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Ordinary Shares to be sold thereunder, the undersigned shall be released from all obligations under this lock-up agreement.

The undersigned hereby consents to receipt of this lock-up agreement in electronic form and understands and agrees that this lock-up agreement may be signed electronically. In the event that any signature is delivered by facsimile transmission, electronic mail, or otherwise by electronic transmission evidencing an intent to sign this lock-up agreement, such facsimile transmission, electronic mail or other electronic transmission shall create a valid and binding obligation of the undersigned with the same force and effect as if such signature were an original.

This lock-up agreement and any claim, controversy or dispute arising under or related to this lock-up agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
