fees and expenses, but excluding the expenses of any attorneys who are employees of the Indemnified Party), and (b) remain responsible for any and all other Losses that the Indemnified Party may incur or suffer resulting from, arising out of,
relating to, in the nature of or caused by the Third Party Claim to the fullest extent provided in this Section 10.

 10.5.2. Mitigation. Indemnified Parties shall use commercially reasonable efforts to
mitigate any Losses that may provide the basis for an indemnifiable claim (that is, the Indemnified Parties shall mitigate such Losses in the same manner that they would mitigate such Losses in the absence of the indemnification provided for in this
Agreement provided, however, that the Indemnified Parties shall not be required to incur any undue expense or take any action that would cause undue hardship, including impairing its ability to conduct business). Any request for
indemnification of specific costs shall include invoices and supporting documents containing reasonably detailed information about the costs and/or damages for which indemnification is being sought.

Section 10 without regard to the availability of remedy under any other provision of this Section 10. 

10.7. Knowledge and Investigation. If any condition contained in this Agreement or in any Ancillary Agreement based on the truth

Section 10 based on such representation, warranty, covenant or agreement shall be deemed waived at Closing to the extent such waiver expressly states that such right to indemnification is also being waived. 

10.8. No Right of Set-Off. The Buyer expressly waives any and all right of set-off against the Milestone Payment, the Milestone
Buyout and the Promissory Note, including any and all right to apply the amount of any Losses referenced in this Section 10 against the Milestone Payment, the Milestone Buyout and the Promissory Note.

to or arising in connection with (a) any breach of, or inaccuracy in any representation or warranty made in connection with this Agreement, (b) any breach or violation of any covenant or agreement in or pursuant to this Agreement or any
Ancillary Agreement which does not require performance after the Closing Date or any other Losses that arise in connection with this Agreement or with respect to which indemnification is provided in this Section 10; provided, however,
the remedies provided in this Section 10 shall not be exclusive of, or limit, any other remedies that may be available to any Indemnified Party in the case of any Losses arising in connection with the commission of fraud or in connection

close of business on the Closing Date, except that, any item caused by the Buyer outside the Ordinary Course of Business of the Company and resulting in Tax that is incurred after the event of Closing, but on the Closing Date, shall be allocated

 Each of the parties to this Agreement may
specify different address or facsimile number by giving notice in accordance with this Section 12.1 to each of the other parties hereto. 
 12.2. Succession and Assignment; No Third-Party Beneficiary. Subject to the immediately following sentence, this Agreement shall be binding upon and inure to the benefit of the parties hereto and
their respective permitted successors and permitted assigns, each of which such permitted successors and permitted assigns shall be deemed to be party hereto for all purposes hereof. The Seller may assign or otherwise transfer any or all of its
rights or interests under this Agreement to receive any Milestone Payment (or Milestone Buyout, as applicable) from Buyer, with the consent of the Buyer, which such consent shall not be unreasonably withheld or delayed, and provided further, that
the Seller shall have entered into an indemnity and release in favor of the Buyer, confirming that Buyer’s obligations to the Seller to make any Milestone Payment or Milestone Buyout payment shall be deemed to be discharged and satisfied in
full to the extent Buyer makes such payments to the Seller’s designated assignee in accordance with the written payment instructions furnished to the Buyer by or on behalf of the Seller, in form and substance reasonably satisfactory to Buyer.
The Buyer, and other than as provided in the prior sentence, the Seller, may not assign, delegate or otherwise transfer either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other
party. Notwithstanding the foregoing, without the consent of the other party, (a) each party hereto may (i) assign any or all of its rights and interests hereunder to one or more of its Affiliates, and (ii) designate one or more of
its Affiliates to perform its obligations hereunder, in each case, so long as the assigning party is not relieved of any Liability hereunder, and (b) the Buyer may assign and delegate this Agreement and all of its rights, interests and
obligations hereunder to Qualified Successor (i) in connection with Change of Control of Buyer with such Qualified Successor or (ii) in connection with Product Transfer to such Qualified Successor, so long as, in the case of subsections
(b)(i) and (b)(ii) of this Section 12.2, such Qualified Successor unconditionally assumes all of the Buyer’s Liabilities under this Agreement. Any such assignment and delegation of this Agreement made in conformity with subsection
(b)

  
 -50-









 
of this Section 12.2 shall operate to relieve the Buyer of its liabilities and obligations hereunder if such Qualified Successor expressly and unconditionally agrees in writing with
Seller that it shall be bound by and shall assume, pay and perform all of the Buyer’s obligations as set forth in Section 2.5.3 of this Agreement. Except as expressly provided herein, this Agreement is for the sole benefit of the
parties hereto and their permitted successors and permitted assignees and nothing herein expressed or implied shall give or be construed to give any Person, other than the parties hereto and such successors and assignees, any legal or equitable
rights hereunder 
 12.3. Amendments and Waivers. No amendment or waiver of any provision of this Agreement shall be
valid and binding unless it is in writing and signed, in the case of an amendment, by the Buyer and the Seller, or in the case of waiver, by the party against whom the waiver is to be effective. No waiver by any party hereto of any breach or
violation or default under, or inaccuracy in, any representation, warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent breach, violation, default under, or inaccuracy in, any such
representation, warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. No delay or omission on the part of any party hereto in exercising any right, power or remedy under this
Agreement shall operate as waiver thereof. 
 12.4. Entire Agreement. This Agreement, together with the Ancillary
Agreements and any documents, instruments and certificates explicitly referred to herein, constitutes the entire agreement among the parties hereto with respect to the subject matter hereof and supersedes any and all prior discussions, negotiations,
proposals, undertakings, understandings and agreements, whether written or oral, with respect thereto, except for the Confidentiality Agreements. 
 12.5. Exhibits; Listed Documents, etc. The listing or description of any item, matter or document in any Schedule hereto will be deemed to modify, qualify or disclose an exception to any
representation or warranty of any party made herein or in connection herewith to which it reasonably relates. 
 12.6.
Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute but one and the same instrument. This Agreement shall become effective when duly
executed by each party hereto. 
 12.7. Severability. Any term or provision of this Agreement that is invalid or
unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any
other jurisdiction. In the event that any provision hereof would, under applicable Legal Requirements, be invalid or unenforceable in any respect, each party hereto intends that such provision shall be construed by modifying or limiting it so as to
be valid and enforceable to the maximum extent compatible with, and possible under, applicable Legal Requirements. 
 12.8.
Headings. The headings contained in this Agreement are for convenience purposes only and shall not in any way affect the meaning or interpretation hereof.

 12.9. Construction. The parties have participated jointly in the negotiation and
drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring
any party by virtue of the authorship of any of the provisions of this Agreement. The parties intend that each representation, warranty and covenant contained herein shall have independent significance. Except as otherwise set forth herein, if any
party has breached or violated, or if there is an inaccuracy in, any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the party has not breached or violated, or in respect of which there is not an inaccuracy, shall not detract from or mitigate the fact that the party has breached or violated, or there is an
inaccuracy in, the first representation, warranty or covenant. 
 12.10. Governing Law. This Agreement, the rights of the
parties and all Actions arising in whole or in part under or in connection herewith, shall be governed by and construed in accordance with the domestic substantive Legal Requirements of the State of New York, without giving effect to any choice or
conflict of law provision or rule (other than Section 5-1401 and 5-1402 of the New York General Obligation Law) that would cause the application of the Legal Requirements of any other jurisdiction. 

12.11. Dispute Resolution. 
 12.11.1. If a dispute arises under this Agreement which cannot be resolved by the Buyer and the Seller prior to initiating an Action, either party hereto may invoke the dispute resolution procedure set
forth in this Section 12.11 by giving written notice to the other party hereto, designating an executive officer with appropriate authority to be its representative in negotiations relating to the dispute. Upon receipt of such written
notice, the other party hereto shall, within [**] days, designate an executive officer with similar authority to be its representative. The designated executive officers shall, following whatever investigation each deems appropriate, promptly enter
into discussions concerning the dispute. Neither party may commence an Action of any matter hereunder (other than injunctive or other equitable relief) until the expiration of [**] days after its notice designating such executive officers.

 12.11.2. Notwithstanding the last sentence of Section 12.11.1, in the event that the Seller elects to dispute
the Buyers FDACM Notice certification described in Section 2.6.1(ii)(b), the parties will submit the matter to non-binding mediation and binding arbitration as follows : 

(a) The parties shall first submit such dispute to panel of three (3) experts in the field of clinical development
of antibiotic drugs, one (1) expert to be appointed by the Seller within [**] days from the notice of initiation of arbitration, one (1) expert to be appointed by the Buyer within [**] days from the notice of initiation of arbitration, and
the third expert to be selected by mutual agreement of the Seller’s appointed expert and the Buyer’s appointed expert within [**] days of the date that the last of such experts was appointed. The three experts shall be instructed by the
parties to complete the arbitration within [**] days after selection of the final expert. The third expert shall be wholly independent of each party shall not have any conflicts of interest with either the Buyer, the Seller or the Company.


  
 -52-









 (b) If either party disagrees with the final decision of the panel of
experts under Section 12 11.2a, or the parties fail to select such panel of experts within [**] days from the notice of initiation of arbitration, the disputed matter shall be resolved in binding arbitration in New York, New York before
single independent arbitrator appointed jointly by the Seller and the Buyer. The arbitration shall be administered by JAMS pursuant to its (Comprehensive Arbitration Rules and Procedures) (Streamlined Arbitration Rules and Procedures) or, if agreed
by the Buyer and the Seller in writing, any alternate provider pursuant to its rules and procedures. 
 (c) Each
party hereto shall bear 50% of the experts’ and arbitrators’ fees and the applicable filing costs, but each party hereto shall bear sole responsibility for its own legal, accounting, advisory and other fees associated with proceedings
under Section 12.11.2a and Section 12.11.2b. The experts and arbitrator shall resolve only those matters in dispute. Judgment of the arbitrator on the award may be entered in any court having jurisdiction. This
Section 12.11.2 shall not preclude the parties hereto from seeking provisional remedies in aid of arbitration from court of appropriate jurisdiction. 

(d) During the pendency of any mediation or arbitration proceeding under Section 12.11.2a and
Section 12.11.2b, the Seller Payment shall not be due and interest thereon shall not begin to accrue and shall be suspended until the dispute has been finally resolved. 

12.12. Jurisdiction; Venue; Service of Process. 
 12.12.1. Jurisdiction. Subject to the provisions of Section 10.4.5 and Section 12.11, each party hereto, by its execution hereof, (a) hereby irrevocably submits to the
exclusive jurisdiction of the United States District Court for the Southern District of New York or any New York state court sitting in New York, New York, United States of America for the purpose of any Action between the parties arising in whole
or in part under or in connection with this Agreement, (b) hereby waives to the extent not prohibited by applicable Legal Requirements, and agrees not to assert, by way of motion, as defense or otherwise, in any such Action, any claim that it
is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that any such Action brought in one of the above-named courts should be dismissed on grounds of forum non
conveniens, should be transferred or removed to any court other than one of the above-named courts, or should be stayed by reason of the pendency of some other proceeding in any other court other than one of the above-named courts, or that this
Agreement or the subject matter hereof may not be enforced in or by such court and (c) hereby agrees not to commence any such Action other than before one of the above-named courts. Notwithstanding the previous sentence, party may commence any
Action in court other than the above-named courts solely for the purpose of enforcing an order or judgment issued by one of the above-named courts. 

  
 -53-









 12.12.2. Venue. Each party waives any claim and shall not assert that venue should
properly lie in any other location within the selected jurisdiction. 
 12.12.3. Service of Process. Each party hereby
(a) consents to service of process in any Action between the parties arising in whole or in part under or in connection with this Agreement in any manner permitted by New York Legal Requirements, (b) agrees that service of process made in
accordance with clause (a) or made by registered or certified mail, return receipt requested, at its address specified pursuant to Section 12.1, shall constitute good and valid service of process in any such Action and
(c) waives and agrees not to assert (by way of motion, as a defense, or otherwise) in any such Action any claim that service of process made in accordance with clause (a) or (b) does not constitute good and valid service of process.

 12.12.4. Waiver of Jury Trial. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LEGAL REQUIREMENTS THAT CANNOT BE WAIVED,
THE PARTIES HEREBY WAIVE, AND COVENANT THAT THEY SHALL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE
CONTEMPLATED TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING,
VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE ITS RIGHT TO TRIAL BY JURY IN ANY PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS AGREEMENT OR ANY OF THE CONTEMPLATED TRANSACTIONS, AND SUCH PROCEEDING SHALL INSTEAD
BE TRIED IN COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT JURY.
