1.5 Purchase Price.

(a) In addition to the Assumed Liabilities, as consideration for the sale of the Transferred Assets to Purchaser, (i) at the Closing, Purchaser will pay to Seller, by wire transfer of immediately available funds in US Dollars, the sum of $1,000,000 (the “Closing Consideration”), (ii) on the first annual anniversary of the Closing Date, Purchaser will pay to Seller, by wire transfer of immediately available funds in US Dollars, the sum of $1,000,000 (the “First Anniversary Payment”), (iii) on the second annual anniversary of the Closing Date, Purchaser will pay to Seller, by wire transfer of immediately available funds in US Dollars, the sum of $1,000,000 (the “Second Anniversary Payment”), and (iv) on the third annual anniversary of the Closing Date, Purchaser will pay to Seller, by wire transfer of immediately available funds in US Dollars, the sum of $5,000,000 (the “Third Anniversary Payment”). As further consideration for the sale of the Transferred Assets to Purchaser, within a reasonable time

following the closing of the initial public offering of Purchaser or an Affiliate of Purchaser (such entity, the “Issuer”) pursuant to an effective registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock for the account of the Issuer (the “IPO,” and the closing date of the IPO, the “IPO Closing Date), Purchaser shall, or shall cause the Issuer (if Purchaser is not the Issuer) to, issue to Seller that number of shares of Issuer’s Common Stock equal to (A) $27,000,000 divided by (B) the price per share of Issuer’s Common Stock offered to the public in the IPO, rounded down to the nearest full share (such shares, the “Consideration Shares,” and the issuance of such shares, the “Share Payment”). The Share Payment will be subject to Seller’s execution and delivery of a Common Stock Purchase Agreement substantially in the form attached hereto as Exhibit A and compliance with applicable securities laws. In the event that the IPO Closing Date occurs prior to the payment of the First Anniversary Payment, the Second Anniversary Payment and/or the Third Anniversary Payment, then Purchaser shall pay to Seller by wire transfer of immediately available funds in US Dollars, immediately following the IPO Closing Date, the First Anniversary Payment, the Second Anniversary Payment and/or the Third Anniversary Payment (in each case only to the extent Purchaser has not previously paid such amounts to Seller). Seller shall provide Purchaser with its wire instructions at least two Business Days prior to a date on which Purchaser will pay Seller via a wire transfer of funds; provided, that if Seller does not provide Purchaser wire instructions within such two Business Day period, Purchaser shall be entitled to rely on the most recent wire instructions previously provided by Seller.

(b) In the event of a sale by Purchaser to a Third Party of all or substantially all of the assets of Purchaser and its Affiliates (an “Asset Sale”) prior to the IPO Closing Date, Purchaser shall pay to Seller, in full satisfaction of Purchaser’s obligation set forth in Section 1.5(a), (i) the First Anniversary Payment, the Second Anniversary Payment and/or the Third Anniversary Payment, in each case only to the extent Purchaser has not previously paid such amounts to Seller pursuant to Section 1.5(a), and (ii) consideration, in the same form received by Purchaser in the Asset Sale, equal to $27,000,000.

(c) In the event of a consolidation with, or merger of Purchaser into, a Third Party (a “Corporate Transaction”) prior to the IPO Closing Date, (i) if the surviving entity in the Corporate Transaction is not an entity with a class of stock publicly traded on a national securities exchange, the surviving entity shall assume the obligations of Purchaser set forth in Sections 1.5(a) and 1.5(b), as applicable, and (ii) if the surviving entity in the Corporate Transaction is an entity with a class of stock publicly traded on a national securities exchange, Purchaser shall pay to Seller immediately following the closing of the Corporate Transaction, in full satisfaction of Purchaser’s obligations set forth in Section 1.5(a), (A) the First Anniversary Payment, the Second Anniversary Payment and/or the Third Anniversary Payment, in each case only to the extent Purchaser has not previously paid such amounts to Seller pursuant to Section 1.5(a), and (B) consideration, in the same form received by Purchaser in the Corporate Transaction, equal to $27,000,000.

(d) Notwithstanding anything to the contrary in Section 1.5(b)(ii) or 1.5(c)(ii)(B), if Purchaser receives as consideration in an Asset Sale or a Corporate Transaction securities that are traded on a securities exchange, the value of such securities shall be deemed to be the average of the closing prices of the securities on such exchange or market over the thirty (30) day period ending three (3) days prior to the closing of such transaction.

(e) The value of any non-cash consideration to be received by Seller pursuant to Sections 1.5(b) or 1.5(c) shall be as mutually agreed by Seller and Purchaser in good faith and consistent with the valuation ascribed to such non-cash consideration in the definitive agreements with respect to the underlying transaction, and provided that such valuation shall be no less favorable with respect to Seller than with respect to the equityholders of Purchaser in connection with such transaction or any related distribution; provided further, that in connection with such determination, Seller shall be provided with a

copy of the definitive transaction agreement with respect to the Asset Sale or Corporate Transaction, as applicable.

(f) Prior to the Share Payment, Seller shall have no rights of a shareholder of Purchaser with respect to the Consideration Shares, including, without limitation, any dividend rights, voting rights, liquidation rights, preemptive rights or other equity rights.

1.6 Sales and Transfer Taxes. Seller will bear and pay any and all Taxes, charges, fees or expenses that may become payable in connection with the Transactions.

1.7 Allocation of Purchase Price. Within 60 days after the Closing, Purchaser shall deliver to Seller an allocation statement reasonably acceptable to Seller setting forth Purchaser’s allocation of the Purchase Price for Tax purposes pursuant to Section 1060 of the Code and any other applicable Tax Laws (the “Allocation Statement”). Purchaser and Seller shall each file all Tax Returns (such as IRS Form 8594, to the extent applicable, or any other forms or reports required to be filed pursuant to Section 1060 of the Code or any comparable provisions of Law) in accordance with the Allocation Statement and, except as otherwise required by Law, Purchaser and Seller shall refrain from taking any action or position inconsistent therewith, including in any examination of any such Tax Return, in any refund claim or in any tax litigation. In the event of any adjustment to the Purchase Price for any reason, a supplemental Allocation Statement shall be prepared and delivered by Purchaser pursuant to this Section 1.7, and the Parties agree to comply with this Section 1.7 with respect to the supplemental Allocation Statement.

1.8 License to Purchaser. Effective as of the Closing, and subject to all the terms and conditions of this Agreement, Seller hereby grants to Purchaser a perpetual (unless terminated pursuant to 7.1), irrevocable (unless terminated pursuant to Section 7.1), transferrable, royalty-free, fully paid-up, sublicensable through multiple tiers, worldwide license, under any Unfiled Program Know-How Patents and the Program Know-How, solely to operate the Business and Exploit Program Materials. The foregoing license shall be exclusive in the Excluded Field (but not for the Permitted Activities) (each as defined in Section 5.8) and otherwise non-exclusive. For the avoidance of doubt, to the extent any Program Know-How or any Unfiled Program Know-How Patents of Seller and/or its Affiliates fall(s) within the definitions of “Company Know-How,” “Company Patent Rights” or “Company Platform Improvements” (as such terms are defined in the Merck Agreement), the foregoing license shall be exclusive to Purchaser in the Excluded Field. Seller grants no license (by implication or otherwise) under any Intellectual Property except as expressly set forth in this Section 1.8.

1.9 Archetype. In order to facilitate Purchaser’s operation of the Business following the Closing, Seller shall provide Purchaser with access to Seller’s generally commercially available Archetype data sequencing database and software (“Archetype”) for a period of two (2) years from the Closing Date on (and subject to the Parties’ execution of) the terms of Seller’s standard Archetype license agreement in the form attached hereto as Exhibit B (the “Archetype License Agreement”).

1.10 Bioinformatics and Sequencing Services. Seller shall, for a period of two (2) years from the Closing Date, use commercially reasonable efforts to provide bioinformatics and genomic sequencing services of substantially the same type and in substantially the same volume as the bioinformatics and genomic sequencing services used by Seller to conduct the Business as currently conducted (the “Supporting Services”). The provision of Supporting Services shall be subject to the Parties’ execution of a mutually agreeable services agreement and the price for such services shall not exceed the lowest prices (on a time and materials or service-by-service basis, as applicable) paid by a Third Party to Seller for substantially the same services in substantially the same volume.

Without limiting the foregoing, the Program Materials constitute and will include, at the time of delivery to Purchaser, all biological materials necessary for the operation of the Business as currently conducted by Seller and its Affiliates.

(d) Section 3.9(d) of the Seller Disclosure Schedule lists the consents to assign the Assigned Contracts to Purchaser and any and all other consents required to transfer, convey and assign the Transferred Assets to Purchaser free and clear of all Encumbrances (the “Required Consents”). Except for the Required Consents, no consents, waivers or approvals are required to transfer and assign the Assigned Contracts or the other Transferred Assets to Purchaser, and no transfer of an Assigned Contract to Purchaser pursuant hereto will conflict with, or result in any violation of or default under (with or without notice or

lapse of time, or both), or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any benefit under, or require any consent, approval or waiver from any Person pursuant thereto.

(e) Merck has not exercised the [***] Research Option (as defined in the Merck Agreement) pursuant to Section 2.1.2 of the Merck Agreement and, other than the payment from Merck pursuant to Section 5.1.1 of the Merck Agreement, Seller has not received any payments of any kind from Merck under the Merck Agreement, and, as of the date of this Agreement, no other payments have accrued from Merck under the Merck Agreement.

ARTICLE 5

COVENANTS

5.1 Access. During the period from the date of this Agreement through the Closing Date (the “Pre-Closing Period”), Seller will, after receiving reasonable advance notice from Purchaser, give Purchaser reasonable access (during normal business hours) to Seller’s books and records relating primarily to the Transferred Assets, and will provide Purchaser with such information regarding the Transferred Assets as Purchaser may reasonably request, for the sole purposes of enabling Purchaser (a) to further investigate, at Purchaser’s sole expense, the Transferred Assets; and (b) to verify the accuracy of the representations and warranties set forth in Section 3; provided, however, that such access shall not interfere with the normal business and operations of the Business or Seller.

5.2 Ordinary Course. Except as explicitly permitted by this Agreement or as otherwise approved by Purchaser in writing in advance, during the Pre-Closing Period:

(i) Seller will (A) operate the Business in the ordinary course and consistent with past practices; and (B) use reasonable efforts to maintain good relations with the parties to the Assigned Contracts.

(ii) Seller will not (A) sell, license, transfer, assign, license, dispose of or create any Encumbrances in the Transferred Assets, or enter into any agreement or undertake any new obligation with any Person with respect to the Transferred Assets; or (B) terminate or amend any of the Assigned Contracts.

5.3 Required Consents. As soon as practicable following the execution date of this Agreement, Seller shall use reasonable efforts to obtain all Required Consents.

5.4 Prosecution and Maintenance of Program Patents. Until the Closing, Seller shall use commercially reasonable efforts at its own expense to prosecute the Program Patents and defend any challenge or opposition relating thereto. Until the Closing, Seller shall inform Purchaser immediately in the event of any challenge or opposition to the Program Patents, which challenge or opposition shall be considered a Material Adverse Effect.

5.5 Notification of Certain Matters. During the Pre-Closing Period, promptly after obtaining knowledge thereof, Seller shall notify Purchaser of (i) the occurrence or non-occurrence of any fact or event which causes or would be reasonably likely to cause (A) any representation or warranty of Seller contained in this Agreement to be untrue or inaccurate or (B) any covenant, condition or agreement of Seller in this Agreement not to be complied with or satisfied in full, and (ii) any failure of Seller to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that no such notification shall affect the representations or warranties of Seller or Purchaser’s right to rely thereon, or the conditions to the obligations of Purchaser except as provided in this Section 5.5. Seller shall give prompt notice in writing to Purchaser of any notice or other communication from any Person alleging that the Consent of such Person is or may be required to be obtained by Seller in connection with the Transactions.

5.6 Tax Matters. Seller and Purchaser shall provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return, amended Tax Return or claim for refund with respect to the Business or the Transferred Assets, in determining liability for Taxes or a right to refund of Taxes or in conducting any audit or other proceeding in respect of Taxes with respect to the Business or the Transferred Assets. Seller shall (i) continue to file all Tax Returns within the time period for filing, and such Tax Returns shall be true, correct and complete in all material respects, and (ii) pay when due any and all Taxes attributable to or levied or imposed upon the Transferred Assets for periods (or portions thereof) through and including the date of the Closing Date whether or not such payment is required to be paid after the Closing Date.

5.7 Delivery. Within thirty (30) days following the Closing, Seller shall complete delivery to Purchaser of all Transferred Assets, including, without limitation, physical delivery of (a) all Program Materials and other Transferred Assets that are tangible assets in Seller’s and/or its Affiliates’ possession or control and (b) copies or other reproductions in writing or electronic format of all Books and Records and all written (including electronic) records of Program Know-How, including written (including electronic) records of “Company Know-How” as defined in the Merck Agreement.

5.8 Restrictive Covenants.

(a) In order to protect the value of the Business, for a period of seven (7) years after the Closing Date (the “Restricted Period”), Seller shall not, and shall cause its Affiliates not to, directly or indirectly, either for itself or for or on behalf of any other Person, engage in the research, development, commercialization or other Exploitation of any [***] (the “Excluded Field”). For the avoidance of doubt, the Excluded Field includes the “Field” as defined in the Merck Agreement. Notwithstanding the foregoing: (i) the reference to Affiliates in the foregoing of this Section 5.8(a) does not include (and Section 5.8(a) shall not apply to) any of the Acquirer Entities; and (ii) nothing herein shall prohibit Seller from (A) performing any services for Purchaser; or (B) licensing or providing Intellectual Property or Know-How or performing services (e.g. gene-editing, gene synthesis, offering Archetype™), in each case, not specifically directed to the Excluded Field even if the licensee or recipient of such Intellectual Property, Know-How or services uses such to engage in activities in the Excluded Field; or (C) any of the Other Phage Activities (whether alone or with any third party) (collectively, the “Permitted Activities”).

(b) For a period of three (3) years after the Closing Date, Seller shall not directly or indirectly through another Person, solicit for employment or induce or attempt to induce or encourage the Key Employee to leave the employ or service of Purchaser or any of its Affiliates or in any way interfere with the employment relationship between Purchaser or any of its Affiliates and the Key Employee; provided, however, that general advertising over the Internet, in print media or other mass media shall not be deemed to be a solicitation or inducement of or interference with respect to the Key Employee in violation of this sentence so long as such general advertising is not targeted or directed at the Key Employee. Seller and its Affiliates shall not hire or enter into a consulting relationship with or otherwise employ or engage the Key Employee in any capacity that induces the Key Employee to leave the employ or service of Purchaser or any of its Affiliates at any time during the three (3) year period after the Closing Date.

(c) For purposes of this Agreement, “Confidential Information” shall mean all information (whether or not in written or electronic form and whether or not expressly designated as confidential) exclusively relating to the Business and the Transferred Assets. At all times (including after the Restricted Period), Seller shall safeguard and hold all Confidential Information in strict confidence, and shall not, directly or indirectly in any capacity communicate, reveal, report, publish, disclose or transfer any Confidential Information to any Person (other than Purchaser or its Affiliates) or use any Confidential Information in any manner or for the benefit of any Person (other than Purchaser or its Affiliates). Notwithstanding the foregoing, Seller may disclose Confidential Information: (i) with Purchaser’s prior written consent or following Purchaser’s public disclosure of such Confidential Information; (ii) to a financial advisor or accountant who is subject to an obligation of confidence, solely for the purpose of obtaining advice or services from such Person pertaining to Seller’s Tax Returns or other Tax obligations; or (iii) to the extent the disclosure is required by a valid order of a court or other Governmental Authority having jurisdiction, provided that Seller gives prior written notice to Purchaser of such required disclosure, uses reasonable efforts to obtain (or assist Purchaser in obtaining) a protective order preventing or limiting the disclosure, and discloses only so much of the Confidential Information as is required by such order. Any copy or reproduction of any Confidential Information relating directly or indirectly to the Business or the Transferred Assets shall, after the Closing, be the property of Purchaser and shall be delivered to Purchaser by Seller pursuant to Section 5.7. Seller shall not make copies or otherwise reproduce Confidential Information in any form except with Purchaser’s prior written consent, and shall deliver to Purchaser or destroy any and all such copies and reproductions upon Purchaser’s request.

(d) Seller acknowledges that Purchaser has invested and will invest substantial time and money to acquire the Transferred Assets and to develop the Business, and the covenants set forth in Sections 5.8(a), (b), and (c) are a material part of the agreement between the Parties, are an integral part of the obligations of Seller hereunder, are supported by good and adequate consideration, and are reasonable and necessary to protect the legitimate business interests of Purchaser, and Purchaser would not consummate the Transactions unless the covenants set forth in Sections 5.8(a), (b) and (c) were in full force and effect and constituted a binding and enforceable contract of Seller. Seller further acknowledges that the duration and geographic territory contained in Section 5.8(a) are reasonable in all respects and necessary to protect the goodwill of the Business and that, without such protection, Purchaser’s or any of its Affiliates’ competitive advantage would be adversely affected. Notwithstanding any other provision of this Agreement (including Section 9.13), the Parties agree that: (i) the covenants in Sections 5.8(a), (b), and (c) are severable and separate, and the unenforceability of any specific covenant will not affect the continuing validity and enforceability of any other covenant; and (ii) in the event any court of competent jurisdiction determines that any of the scope, time or territorial restrictions set forth in Section 5.8(a), (b), or (c) are unreasonable and therefore unenforceable, then the Parties agree that such provision will be enforced to the fullest extent that the court deems reasonable and this Agreement will thereby be reformed.

(e) Seller acknowledges that a breach or threatened breach of any of the provisions in this Section 5.8 would give rise to irreparable harm to Purchaser, for which monetary damages would not

be an adequate remedy, and hereby agrees that in the event of a breach or a threatened breach by Seller of any such provisions, Purchaser shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an injunction, specific performance or any other equitable relief that may be available from a court of competent jurisdiction (without any requirement to post bond).

5.9 Further Actions; NIH Grant Assistance.

(a) The Parties shall cooperate reasonably with each other and with their respective representatives in connection with any steps required to be taken as part of their respective obligations under this Agreement, including the timely assignment, conveyance or other Transfer of the Transferred Assets to Purchaser and the consolidation, vesting and recordation of the full ownership thereof. The Parties shall (i) furnish upon request to each other such further information, (ii) execute and deliver to each other such other documents, and (iii) do such other acts and things, all as the other Party may reasonably request for the purpose of carrying out the intent of this Agreement; provided, however, that none of the above undertakings shall require the payment of expenses by Purchaser or otherwise materially increase the obligations of Purchaser or Seller beyond those expressly set forth in this Agreement.

(b) The Parties acknowledge that the NIAID R21/R33 Award granted to Seller (the “NIH Grant”) will not be assigned by Seller to Purchaser hereunder. Upon Purchaser’s request before and after Closing, and at Purchaser’s reasonable expense, Seller shall provide such assistance and take such steps as are reasonably requested by Purchaser with respect to transfer of the NIH Grant to Purchaser, including enabling the Key Employee to initiate the process and petition for the transfer of the NIH Grant prior to the Closing while the Key Employee is still employed by Seller.

(c) Without limiting the above, during the thirty (30) day period following Closing (the “Post-Closing Period”), Seller shall use commercially reasonable efforts to facilitate the ongoing work and wind-down of activities under the Merck Agreement and the transition from Seller to Purchaser of all activities under the Merck Agreement, including, without limitation, by allowing the Designated Personnel (as defined below) to conduct the Research Program (as defined in the Merck Agreement) and maintaining and committing the same resources, equipment, facilities (including laboratory) at Seller as Seller maintained and committed to conduct the Research Program prior to Closing (subject to a reasonable wind-down to transition the Research Program to Purchaser) and by providing the Key Employee with access to such resources, equipment and facilities (including laboratory) at Seller and reasonable assistance from such personnel at Seller in order for the Key Employee, on behalf of Purchaser, to carry out and transition to Purchaser the Research Program and other activities under the Merck Agreement. Seller agrees that any and all Know-How that is first generated, conceived, developed, discovered, reduced to practice or otherwise made by Designated Personnel in the course of conducting the Research Program or other activities under the Merck Agreement during the Post-Closing Period and all Intellectual Property therein and thereto (collectively, “Merck Program IP”) shall be owned by Purchaser. “Designated Personnel” shall mean Key Employee, Yvette Del Rosario, Lisa Kieweg-Thompson and Paula Patterson, who shall be the only individuals conducting research and development activities for the Research Program during the Post-Closing Period. Seller hereby irrevocably and unconditionally assigns to Purchaser all right, title and interest worldwide in and to all Merck Program IP. At Purchaser’s request and reasonable expense, Seller shall execute and deliver assignments of Merck Program IP to Purchaser or its designee and shall execute other papers and otherwise assist Purchaser as reasonably requested by Purchaser (including, without limitation, executing documents for prosecuting Patents) to apply for, obtain, perfect, maintain and enforce Purchaser’s right, title and interest in Merck Program IP. Seller also shall require that any Designated Personnel who conducts the Research Program or other activities under the Merck Agreement for or on behalf of Seller during the Post-Closing Period shall be under an obligation to assign, and shall assign, to Seller any and all Merck Program IP made by such Person.

(a) This Agreement may be terminated before the Closing:

(i) by mutual written consent of Seller and Purchaser;

(ii) by either Seller or Purchaser by written notice to the other if the Closing has not occurred on or before March 31, 2018; provided, however, that the right to terminate this Agreement under this Section 7.1(b) shall not be available to a Party whose breach of any representation, warranty, covenant, or agreement under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before such date;

(iii) by either Seller or Purchaser if a court of competent jurisdiction or other Governmental Authority shall have issued a final and nonappealable order, decree or ruling, or shall have taken any other action, having the effect of permanently restraining, enjoining or otherwise prohibiting any of the Transactions; or

(iv) by either Party if the other Party (the “Breaching Party”) materially breaches any covenant or obligations of the Breaching Party which breach has not been cured within 10 days after delivery of notice of such breach to the Breaching Party by the non-breaching Party.

(b) This Agreement may be terminated by Purchaser before Closing or thereafter on or before the date that is thirty (30) days after the third anniversary of the Closing Date if the Merck Agreement is terminated pursuant to Section 8.2 of the Merck Agreement at any time within three (3) years after the Closing Date.

7.2 Termination Procedures. If either Party wishes to terminate this Agreement pursuant to Section 7.1, such Party will deliver to the other Party a written notice stating that such Party is terminating this Agreement and setting forth a brief statement of the basis on which such Party is terminating this Agreement.

7.3 Effect of Termination.

(a) Upon the termination of this Agreement pursuant to Article 7: (i) no Party will have any obligation or other Liability to the other Party, except that (A) the Parties will remain bound by the provisions of Article 8, and (B) the termination of this Agreement shall not relieve either Party from any Liability for any breach of any covenant or agreement in this Agreement prior to such termination; and (ii) the license set forth in Section 1.8 shall terminate. For clarity, Section 1.5 and Section 5.8 shall terminate upon termination of this Agreement.

(b) Notwithstanding the foregoing, if Purchaser terminates this Agreement pursuant to Section 7.1(b), (i) Purchaser shall transfer, convey and assign back, pursuant to a mutually agreeable form of assignment, to Seller all Transferred Assets, including the Assigned Contracts, together with all Assumed Liabilities (mutatis mutandis) (provided, however, that Purchaser shall remain liable for any Assumed Liabilities arising under the Assigned Contracts after the Closing Date and prior to such re-assignment arising from any breach, default, violation or failure to perform by Purchaser or any of its Affiliates of any provision under any Assigned Contract after the Closing Date but on or before the date of such re-assignment or any events or circumstances occurring after the Closing Date but on or before the date of such re-assignment which with notice or lapse of time, would constitute or result in a breach by Purchaser of any Assigned Contract) and (ii) if and to the extent Purchaser owns or controls any Purchaser Transferred Assets IP at the time Purchaser terminates this Agreement pursuant to Section 7.1(b) (the “Termination Date”), Purchaser shall (A) transfer, convey and assign to Seller such Purchaser Transferred Assets IP that is owned or otherwise controlled (with the right to transfer) by Purchaser and/or its Affiliates and used exclusively in the Business as conducted by Purchaser and its Affiliates as of or any time prior to the Termination Date and (B) grant to Seller a perpetual, irrevocable, transferrable, royalty-free, fully paid-up, sublicensable through multiple tiers, worldwide, license under such other Purchaser Transferred Assets IP as existing at the Termination Date and necessary for the operation of the Business as conducted by Purchaser and its Affiliates as of or any time prior to the Termination Date, solely to operate the Business and Exploit Program Materials, which license shall be exclusive in the Excluded Field and otherwise non-exclusive; provided, however, that Seller shall have no obligation to assume any liabilities of Purchaser with respect to Purchaser Transferred Assets IP. All of such Transferred Assets and the Purchaser Transferred Assets IP that is transferred to Seller pursuant to clause (A) above shall become the confidential information of Seller in the same manner with Purchaser being bound to such information in the same manner as Seller is bound with respect to Confidential Information. For the avoidance of doubt, Purchaser Transferred Assets IP shall not include any Know-How or other Intellectual Property developed, owned or controlled by Purchaser and/or its Affiliates (1) prior to the Closing Date or (2) at any time after the Closing Date independent of the Transferred Assets or the license in Section 1.8 (i.e., other than exclusively from the use of the Transferred Assets or exercise of the license in Section 1.8), including such prior-existing and/or independently developed Intellectual Property related to the discovery, research, process development and/or manufacturing of bacteriophage and including any Patents claiming or covering, in whole or in part, any such prior-existing and/or independently developed Intellectual Property (collectively, “Purchaser Background IP”), and Seller shall have no rights, interests or licenses in or to, and Purchaser grants no license (by implication or otherwise) to Seller under, any Purchaser Background IP. Without limiting the foregoing, Purchaser Background IP includes, without limitation, all scientific and technical information and other Know-How and material, including but not limited to the isolation, phenotypic and genotypic characterization, evolution, modification, fermentation, purification, formulation, phage cocktails and construction thereof, and the bacterial and phage libraries for the following five (5) phage

programs: Klebsiella pneumoniae, Acinetobacter baumannii, Streptococcus mutans, Escherichia coli, and Pseudomonas aeruginosa (but not any Transferred Assets or any Program Know-How relating to Pseudomonas aeruginosa), and any Patents that cover or claim the foregoing in whole or in part, and Seller acknowledges and agrees that Purchaser is and shall remain the sole and exclusive owner of all right, title, and interest in and to all Purchaser Background IP.

ARTICLE 8

SURVIVAL; INDEMNIFICATION

8.1 Survival. All representations and warranties in Articles 3 and 4 of this Agreement shall survive the Closing and expire on the date that is twelve (12) months after the Closing Date (the “General Indemnity Termination Date”), except that the representations and warranties of Seller contained in (i) Sections 3.3 (Sufficiency of Assets) and 3.8 (Intellectual Property) (together, the “IP Assets Representations”) shall survive the Closing and expire on the date that is three (3) years after the Closing Date, (ii) Sections 3.1 (Organization; Authority; Binding Obligation), 3.2 (Title to Transferred Assets), 3.13 (Disclosure) and 3.14 (Brokers and Finders) shall survive the Closing and expire on the date that is six (6) years after the Closing Date and (iii) Section 3.7 (Tax Matters) shall survive the Closing and expire on the date that is sixty (60) days after the expiration of the maximum statute of limitations applicable to such matters (such dates in clauses (i), (ii) and (iii) together with the General Indemnity Termination Date, as applied to the applicable representation and warranty, an “Expiration Date,” and the representations and warranties of Seller contained in the Sections referenced in clauses (ii) and (iii), collectively, the “Fundamental Representations”). If Purchaser or Seller delivers to the other Party, before the applicable Expiration Date, either a Claim Notice or an Indemnification Demand based upon a breach of a representation or warranty in Article 3 or 4 of this Agreement, then the demand for indemnification set forth therein shall survive until, but only for purposes of, the resolution of the matter covered by such Claim Notice or Indemnification Demand. Each covenant and agreement in this Agreement shall survive the Closing without limitation as to time until fully performed in accordance with its terms, and any claims based on Fraud will survive the Closing indefinitely.

8.2 Indemnification by Seller. Subject to the other provisions of this Article 8, Seller shall indemnify Purchaser, its Affiliates and their respective directors, officers, employees, agents, advisors, and representatives (the “Purchaser Indemnified Parties”) in respect of, and hold them harmless against, any Losses suffered by a Purchaser Indemnified Party as a result of (a) the breach by Seller of any representation or warranty of Seller contained in this Agreement, (b) the breach by Seller of any covenant or agreement of Seller contained in this Agreement, (c) any Excluded Liability, or (d) any willful breach or Fraud by Seller in connection with this Agreement or the Transactions.

8.3 Indemnification by Purchaser. Subject to the other provisions of this Article 8, Purchaser shall indemnify Seller, its Affiliates and their respective directors, officers, employees, agents, advisors, and representatives (the “Seller Indemnified Parties”) in respect of, and hold them harmless against, any Losses suffered by a Seller Indemnified Party as a result of (a) the breach by Purchaser of any representation or warranty of Purchaser contained in this Agreement, (b) the breach by Purchaser of any covenant or agreement of Purchaser contained in this Agreement, (c) any failure on the part of Purchaser to perform and discharge the Assumed Liabilities on a timely basis, or (d) any Fraud by Purchaser in connection with this Agreement or the Transactions.

8.4 Indemnification Claims.

(a) No claim for Losses pursuant to Section 8.2(a) or 8.3(a) shall be brought against an indemnifying Party after the applicable Expiration Date.

(b) In the event a Purchaser Indemnified Party becomes aware of a claim by a Third Party (including any action or proceeding commenced or threatened to be commenced by any Third Party) that such Purchaser Indemnified Party reasonably believes may result in a demand against Seller pursuant to Section 8.2, such Purchaser Indemnified Party shall promptly notify Seller in writing of such claim. Likewise, in the event a Seller Indemnified Party becomes aware of a claim by a Third Party that such Seller Indemnified Party reasonably believes may result in a demand against Purchaser for indemnification pursuant to Section 8.3, such Seller Indemnified Party shall promptly notify Purchaser in writing of such claim. For purposes of this Section 8.4, the Party giving any such notice (a “Claim Notice”) shall be deemed to be the “Notifying Party,” and the Party receiving the Claim Notice shall be deemed to be the “Notified Party.” The Claim Notice shall be accompanied by reasonable supporting documentation submitted by the Third Party making such claim and shall describe in reasonable detail (to the extent known by the Notifying Party) the facts constituting the basis for such claim and the amount of the claimed Losses; provided, however, that no delay or failure on the part of the Notifying Party in delivering a Claim Notice shall relieve the Notified Party from any liability hereunder except to the extent of any damage or liability caused by or arising out of such delay or failure. Within twenty (20) days after receipt of any Claim Notice, the Notified Party may, upon written notice thereof to the Notifying Party, assume control of the defense of the claim referred to therein at the Notified Party’s sole cost and expense with counsel reasonably satisfactory to the Notifying Party. If the Notified Party does not so assume control of the defense of such claim, the Notifying Party shall control the defense of such claim at the sole cost and expense of the Notified Party. The Party not controlling the defense of such claim (the “Non-controlling Party”) may participate therein at its own expense; provided, however, that if the Notified Party assumes control of the defense of such claim and the Notified Party and the Notifying Party have materially conflicting interests or different defenses available with respect to such claim which cause the Notifying Party to hire its own separate counsel with respect to such claim, the reasonable fees and expenses of counsel to the Notifying Party shall be considered “Losses” for purposes of this Agreement (subject to the proviso in the definition thereof). The Party controlling the defense of such claim (the “Controlling Party”) shall keep the Non-controlling Party reasonably advised of the status of such claim and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such claim (including copies of any summons, complaint or other pleading which may have been served on such Party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such claim. Neither the Notified Party nor the Notifying Party shall agree to any settlement of, or the entry of any judgment arising from, any such claim without the prior written consent of the other Party, which shall not be unreasonably withheld or delayed; provided, however, that the consent of the Notifying Party shall not be required with respect to any such settlement or judgment if the Notified Party agrees in writing to pay or cause to be paid all amounts payable pursuant to such settlement or judgment (subject to the other limitations in this Article 8), including all monetary obligations of the Notifying Party, and such settlement or judgment neither includes nor creates any non-monetary obligations of the Notifying Party.

(c) Except as otherwise provided in Section 8.4(b) with respect to Third Party claims for which notice has previously been provided, in order to seek indemnification under this Article 8, a Person entitled to indemnification under Section 8.2 or Section 8.3 (an “Indemnified Party”) shall deliver a written demand (an “Indemnification Demand”) to Seller (in the case of an Indemnification Demand from a Purchaser Indemnified Party) or Purchaser (in the case of an Indemnification Demand from a Seller Indemnified Party) which contains (i) a description and the amount (the “Asserted Damages Amount”) of any Losses incurred or reasonably expected to be incurred by the Indemnified Party, (ii) a statement that the Indemnified Party is entitled to indemnification under this Article 8 for such Losses and a reasonable explanation of the basis therefor, and (iii) a demand for payment in the amount of such Losses.

(d) Within twenty (20) days after delivery of an Indemnification Demand to Seller or Purchaser (as the case may be), such Party shall deliver to the other Party a written response (the “Response”) in which the Party providing the Response shall: (i) agree that the Indemnified Party is entitled to receive all of the Asserted Damages Amount (in which case the Response shall be accompanied by a payment to the Indemnified Party of the full Asserted Damages Amount, by check or wire transfer; (ii) agree that the Indemnified Party is entitled to receive part, but not all, of the Asserted Damages Amount (such portion, the “Agreed Portion”) (in which case the Response shall be accompanied by a payment to the Indemnified Party of the Agreed Portion, by check or by wire transfer); or (iii) dispute that the Indemnified Party is entitled to receive any of the Asserted Damages Amount.

(e) In the event that the Party providing a Response pursuant to Section 8.4(d) shall (i) dispute that the Indemnified Party is entitled to receive any of the Asserted Damages Amount, or (ii) agree that the Indemnified Party is entitled to only the Agreed Portion of the Asserted Damages Amount, Purchaser and Seller shall attempt in good faith to agree upon the rights of the respective Party with respect to each of the indemnification claims that comprise the Asserted Damages Amount (or the portion of the Asserted Damages Amount not comprising the Agreed Portion). If Purchaser and Seller should so agree, a memorandum setting forth such agreement shall be prepared and signed by both Parties. If no such agreement can be reached after good faith negotiation within 60 days after delivery of a Response, either Purchaser or Seller may demand arbitration of any matter set forth in the applicable Indemnification Demand. The matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to Purchaser and Seller. In the event that, within 30 days after submission of any dispute to arbitration, Purchaser and Seller cannot mutually agree on one arbitrator, then the Parties shall arrange for the American Arbitration Association to designate a single arbitrator in accordance with the rules of the American Arbitration Association.

(f) Any such arbitration shall be held in Los Angeles County, California, under the rules and procedures then in effect of the American Arbitration Association. The arbitrator shall determine how all expenses relating to the arbitration shall be paid, including the respective expenses of each Party, the fees of the arbitrator and the administrative fee of the American Arbitration Association. The arbitrator shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing Purchaser and Seller an opportunity, adequate in the sole judgment of the arbitrator, to discover relevant information from the opposing Party about the subject matter of the dispute. The arbitrator shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys’ fees and costs, to the same extent as a competent court of law or equity, should the arbitrator determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of the arbitrator as to the validity and amount of any indemnification claim in such Indemnification Demand shall be final, binding and conclusive upon the Parties. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator. All payments required by the arbitrator shall be made within 30 days after the decision of the arbitrator is rendered. Judgment upon any award rendered by the arbitrator may be entered in any court having jurisdiction.

8.5 Limitations. Except for Losses based on Fraud or willful breach, the maximum aggregate amount of Losses for which Seller shall be liable (a) under Section 8.2(a) for breach of (i) any Fundamental Representations shall be limited in the aggregate to the Purchase Price actually paid to Seller, (ii) any IP Assets Representations shall be limited in the aggregate to the Purchase Price actually paid to Seller up to $8,000,000,, and (iii) any representation or warranty of Seller other than breach of any Fundamental Representations or the IP Assets Representations shall be limited in the aggregate to an amount equal to [***]% of the Purchase Price actually paid to Seller, and (b) under Section 8.2(b) for breach of any covenant shall be limited in the aggregate to the Purchase Price actually paid to Seller. For purposes of this Section

8.5, the amount of the Purchase Price actually paid to Seller shall be determined as the amount of the Purchase Price that becomes due and payable to Seller pursuant to Section 1.5(a) hereof and is either received by Seller or validly set-off pursuant to a right of set-off of Purchaser arising from Section 8.6 hereof and shall not be limited by the amount of the Purchase Price actually received by Seller at the time such claim is made.

8.6 Set Off. Purchaser shall have the right to withhold and deduct any Losses for which any Purchaser Indemnified Party is entitled to indemnification under this Agreement after application in full of the provisions of Section 8.4 (subject to Section 8.5 hereof) from any payments, including for the avoidance of doubt any Share Payment, that may be owed to Seller pursuant to Section 1.5 (a “Set Off”). For purposes of clarity, Purchaser shall not have to right to a Set Off with respect to any amount that is subject to ongoing dispute pursuant to Section 8.4(e). Neither the exercise nor the failure to exercise a Set-Off will constitute an election of remedies or limit the Purchaser Indemnified Party in any manner in the enforcement of any other remedies that may be available to it under this Agreement.

7. Notwithstanding anything to the contrary in this Amendment, in the event the closing of the Merger Transaction does not occur on or before June 1, 2019, or such other date as the Parties may agree upon in writing, this Amendment shall be null and void and the Agreement will remain in full force and effect without amendment; provided, however, that the $1,000,000 payment made by Purchaser to Seller on January 31, 2019 pursuant to Paragraph 2 of this Amendment will constitute the “First Anniversary Payment” under the Agreement, and Purchaser’s obligation to make the First Anniversary Payment pursuant to Section 1.5(a)(ii) of the Agreement shall be satisfied in full as a result of such payment under this Amendment.
