respects as of the Closing Date, except as specifically disclosed in a document of even date herewith and delivered by Seller to Purchaser referring to the representations and warranties of the Seller in this Agreement (the “Seller
Disclosure Schedules”). The Seller Disclosure Schedules will correspond to the numbered and lettered paragraphs contained in this ARTICLE III, and the disclosure in any such specified schedule of the Seller Disclosure Schedules
shall qualify only the corresponding subsection in this ARTICLE III (except to the extent that the relevance of such disclosure to other sections of the Seller Disclosure Schedules or this Agreement is reasonably apparent on its face from the
content or the disclosure is specifically cross-referenced in another section of the Seller Disclosure Schedules). 
 3.1 Organization
and Qualification. Seller is a corporation duly qualified or licensed to do business and is in good standing in every jurisdiction in which the conduct of its business, or the ownership or lease of its properties, require it to be so qualified
or licensed, except where the failure to be so qualified or licensed would not have a Material Adverse Effect, and has all requisite power and authority to own, operate or lease all of the assets purported to be owned by it, including the Purchased
Assets and all rights of the Seller under Transferred Agreements, and to carry on the Program in all material respects as currently conducted. The Seller has never conducted any business under or otherwise used, for any purpose or in any

and thereby (including the Acquisition). The execution, delivery and performance of this Agreement and the other Transaction Documents by Seller and the consummation by Seller of the transactions contemplated hereby and thereby (including the
Acquisition) have been duly and validly authorized by all necessary corporate action of the Seller, and no other corporate action on the part of the Seller is necessary to authorize this Agreement and the other Transaction Documents or to consummate
the transactions contemplated hereby and thereby (including the Acquisition). This Agreement and the other Transaction Documents have been duly executed and delivered by Seller and, assuming the due authorization, execution and delivery by the other
Parties hereto, each such agreement constitutes a legal, valid and binding obligation of Seller, enforceable against Seller in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or similar Laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

3.3 No Conflict. Except as set forth on Schedule 3.3 of the Seller Disclosure Schedules, the execution and delivery of this Agreement
and the other Transaction Documents by Seller do not, and the performance by Seller of its obligations hereunder and thereunder and the consummation by Seller of the transactions contemplated hereby and thereby (including the


  
 11 








 
Acquisition) will not: (a) conflict with or violate any provision of the Certificate of Incorporation of Seller; (b) assuming that all filings and notifications described in Section 3.4 have

the giving of notice or lapse of time or both would reasonably be expected to become a default) under, or give to others any right of termination, amendment, acceleration or cancellation or modification of, or result in the creation of an
Encumbrance on any of the Purchased Assets or Transferred Agreements; or (d) contravene, conflict with or result in a violation of any of the terms or requirements of, or give any Governmental Authority or Regulatory Authority the right to revoke,

violations, breaches, conflicts, defaults, accelerations, failures to give notice or occurrences of such other events described in clauses (a) through (d) of this Section 3.3 would not, in the aggregate, have a Material Adverse Effect on the
Purchased Assets.
 3.4 Required Filings and Consents. The execution and delivery of this Agreement and the other Transaction
Documents by Seller do not, and the performance by Seller of its obligations hereunder and thereunder and the consummation by Seller of the transactions contemplated hereby and thereby (including the Acquisition) will not, require any consent,
approval, authorization or permit of, or filing by Seller with or notification by Seller to, any Governmental Authority or Regulatory Authority. 

3.5 Intellectual Property. 

(a) Disclosure and Ownership of Program Patents. Schedule 3.5(a) of the Seller Disclosure Schedules lists all of the
Seller-Owned Patents and Seller-Licensed Patents, setting forth in each case the jurisdictions in which the Seller-Owned Patents and Seller-Licensed Patents have been
filed. Except as set forth in Schedule 3.5(a) of the Seller Disclosure Schedules, Seller has a valid, legally enforceable, and exclusive right to use and license all Seller-Owned Patents and
Seller-Licensed Patents. 
 (b) Ownership of and Right to Use Program Know-How and Program IP; No Encumbrances. Except as set forth in Schedule 3.5(b) of the Seller Disclosure Schedules, Seller has good and valid title to, free and clear of all Encumbrances (other than
the Assumed Liabilities and Permitted Encumbrances, and those arising under the Transferred Agreements), or a valid, legally enforceable right to use and license, the Program Know-How and Program IP. 

(c) Agreements Related to Program Technology. The Transferred Agreements constitute all existing Contracts related to the
Program Technology and/or Program Therapy other than (1) non-disclosure agreements and (2) invention assignment agreements with employees, consultants and contractors that assign or grant to the Seller
ownership of inventions and intellectual property developed in the course of providing services to the Seller by such employees, consultants and contractors. 

(d) No Third Party Rights in Program Technology. Except as set forth in Schedule 3.5(d) of the Seller Disclosure Schedules:


  
 12

consultant or independent contractor of the Seller has any right, title or interest in, to or under any Program Technology developed by such person in the course of providing services to the Seller that has not been either (A) irrevocably assigned
or transferred to Seller or (B) licensed (with the right to grant sublicenses) to Seller under an exclusive, irrevocable, worldwide, royalty-free, fully-paid and assignable license. 

(ii) No Challenges. The Seller has not received any written communication from any Person challenging or threatening to
challenge, nor is the Seller a party to any pending and served proceeding or, to Seller’s Knowledge, pending but not served proceeding or threatened proceeding in which any Person is challenging, (A) the Seller’s ownership of, and right to

any basis for any inventorship challenge, interference, invalidity or unenforceability with respect to Program Patents. 
 (f) No
Infringement of Third Party IP Rights. The Seller has never infringed (directly, contributorily, by inducement, or otherwise), misappropriated, or otherwise violated or made unlawful use of any Intellectual Property Right of any other Person or
engaged in unfair competition. No Program IP and no method or process used in the development, current or past manufacturing or use of the Program Therapy infringes, violates, or makes unlawful use of any Intellectual Property Right of, or contains
any Intellectual Property misappropriated from, any other Person. There is no legitimate basis for a claim that the Seller or the Program Therapy has infringed or misappropriated any Intellectual Property Right of another Person or engaged in unfair
competition or that the Program Therapy and any method or process used in the current or past development, manufacturing or use of Program Therapy infringes, violates, or makes unlawful use of any Intellectual Property Right of, or contains any
Intellectual Property misappropriated from, any other Person. Without limiting the generality of the foregoing:

Proceeding is, to the Seller’s Knowledge, pending or threatened against the Seller or against any other Person who is or may be entitled to be indemnified, defended, held harmless, or reimbursed by the Seller with respect to such claim or
Proceeding. The Seller has never received any written notice or, to the Seller’s Knowledge, other communication (in writing or otherwise) relating to any actual, alleged, or suspected infringement, misappropriation, or violation by the Seller,
any of their employees or agents, or any Program Therapy of any Intellectual Property Rights of another Person, including any letter or other communication suggesting or offering that the Seller obtain a license to any Intellectual Property Right of
another Person. 
 (ii) Infringement Claims Affecting In-Licensed IP. To the Seller’s Knowledge, no claim or Proceeding
involving any Intellectual Property or Intellectual Property Right licensed to the Seller is pending or has been threatened, except for any such claim or Proceeding that, if adversely determined, would not materially adversely affect (a) the use or

Seller’s Knowledge, no current or former employee, consultant or contractor is in violation of any term of any such agreement. 

(i) No Government Funding. Except as set forth in Schedule 3.5(i) of the Seller Disclosure Schedule, no funding, facilities

transactions contemplated by this Agreement will not result in a material breach of any Transferred Agreement.

otherwise put into effect, (i) may have an adverse effect on the ownership of the Purchased Assets or on the ability of the Seller to comply with or perform any covenant or obligation under any of the Transaction Documents, or (ii) may have the

employment contract, proprietary information agreement or any other agreement relating to the right of any such individual to be employed by, or to contract with, the Purchaser; and to the Purchaser’s knowledge the continued employment by the
Purchaser of its present employees, and the performance of the Purchaser’s contracts with its independent contractors, will not result in any such violation. The Purchaser has not received any notice alleging that any such violation has
occurred. The Purchaser is not aware that any officer, key employee or group of employees intends to terminate his, her or their employment with the Purchaser, nor does the Purchaser have a present intention to terminate the employment of any

Technology or any intellectual property acquired by Purchaser in connection with this Agreement, (ii) criminal liability, (iii) in which equitable relief is sought against a Purchaser Indemnitee or (iv) with respect to which the
potential Damages (estimated in good faith by the Purchaser Indemnitee) could be reasonably expected to exceed 200% of the then-existing balance of the Indemnification Cap. If Seller assumes the defense of a Purchaser Third Party Claim, Seller may
not consent to the entry of any judgment or enter into any settlement with respect to the Purchaser Third Party Claim without the prior written consent of the Purchaser Indemnitee (not to be unreasonably withheld, conditioned or delayed) if
(A) such judgment or settlement does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Purchaser Indemnitee of a full release from all liability in respect to such Purchaser Third Party Claim,
(B) such judgment or settlement would result in the finding or admission of any violation of Law by Purchaser or the rights of any person, (C) the sole relief provided is anything other than monetary damages or (D) as a result of such
consent or settlement, injunctive or other equitable relief would be imposed against the Purchaser Indemnitee. Purchaser will cooperate, at the expense of Seller, as Seller

may reasonably request in investigating, defending and, subject to the terms set forth above, settling such Purchaser Third Party Claim. If Seller elects not to defend a Purchaser Third Party
Claim, is not permitted to defend such Purchaser Third Party Claim or fails to notify Purchaser of its election as herein provided, Purchaser may pay, compromise, settle or defend such Purchaser Third Party Claim at the sole cost and expense of
Seller if Seller is determined to be liable to Purchaser hereunder, provided, however, that no such payment in compromise or settlement of, or other compromise or settlement of, may be effected by Purchaser without the Seller’s
consent (which shall not be unreasonably withheld, conditioned or delayed). In any event, Seller shall be entitled, at its expense, to participate in any defense of such Purchaser Third Party Claim with the consent of Purchaser, which shall not be
unreasonably withheld, conditioned or delayed. Should any Claim be made or suit or proceeding be instituted against any Seller Indemnitee, which, if prosecuted successfully, would be a matter for which such Seller Indemnitee is entitled to
indemnification pursuant to Section 7.3 (a “Seller Third Party Claim”), Seller shall notify Purchaser within twenty (20) days after Seller’s receipt of notification of the Seller Third Party Claim, including a
description of the factual basis of the Seller Third Party Claim and shall indicate the amount of the Damages. Thereafter, Seller shall promptly deliver to Purchaser copies of all notices and documents (including court papers) received by Seller
relating to the Seller Third Party Claim. Purchaser shall be entitled to participate in the defense of the Seller Third Party Claim and, if it so chooses, to assume the defense thereof at its own expense with counsel selected by Purchaser, if
Purchaser gives written notice to Seller of its election to assume the defense of such Seller Third Party Claim within five (5) days after Purchaser receives notice of such claim from Seller; provided, however, that Purchaser
shall not be entitled to assume the defense of any Claim related to, either directly or indirectly, (i) criminal liability, (ii) in which equitable relief is sought against a Seller Indemnitee or (iii) with respect to which the
potential Damages (estimated in good faith by the Seller Indemnitee) could be reasonably expected to exceed 200% of the then-existing balance of the Indemnification Cap. If Purchaser assumes the defense of a Seller Third Party Claim, Purchaser may
not consent to the entry of any judgment or enter into any settlement with respect to the Seller Third Party Claim without the prior written consent of the Seller Indemnitee (not to be unreasonably withheld or delayed) if (A) such judgment or
settlement does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Seller Indemnitee of a full release from all liability in respect to such Seller Third Party Claim, (B) such judgment or settlement
would result in the finding or admission of any violation of Law by Seller or the rights of any person, (C) the sole relief provided is anything other than monetary damages or (D) as a result of such consent or settlement, injunctive or
other equitable relief would be imposed against the Seller Indemnitee. Seller will cooperate, at the expense of Purchaser, as Purchaser may reasonably request in investigating, defending and, subject to the terms set forth above, settling such
Seller Third Party Claim. If Purchaser elects not to defend a Seller Third Party Claim, is not permitted to defend such Seller Third Party Claim or fails to notify Seller of its election as herein provided, Seller may pay, compromise, settle or
defend such Seller Third Party Claim at the sole cost and expense of Purchaser if Purchaser is determined to be liable to Seller or Seller Indemnitee hereunder, provided, however, that no such payment in compromise or settlement of, or
other compromise or settlement of, may be effected by Seller without the Purchaser’s consent (which shall not be unreasonably withheld or delayed). In any event, Purchaser shall be entitled, at its expense, to participate in any defense of such
Seller Third Party Claim with the consent of Seller, which shall not be unreasonably withheld.

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. If the final judgment of a court of

phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or
provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.
