consequences for so doing).

instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or violation has been waived), (ii) is in violation of any judgment, decree or
order of any court, arbitrator or other governmental authority or (iii) is or has been in violation of any statute, rule, ordinance or regulation of any governmental authority, including without limitation all foreign, federal, state and local

expected to result in a Material Adverse Effect. 
 (n) Regulatory Permits. The Company and the Subsidiaries possess

permits could not reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of
any Material Permit, except where such revocation or modification would not reasonably be expected to have a Material Adverse Effect. 

(o) Title to Assets. Except as set forth on Schedule 3.1(o), the Company and the Subsidiaries have good and
marketable title in fee simple to all real property owned by them and good and marketable title in all personal property owned by them that is material to the business of the Company and the Subsidiaries, in each case free and clear of all Liens,
except for (i) Liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries and (ii) Liens for the payment of
federal, state or other taxes, for which appropriate reserves have been made in accordance with GAAP and, the payment of which is neither delinquent nor subject to penalties. Except as set forth on Schedule 3.1(o), any real property and
facilities held under lease by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases with which the Company and the Subsidiaries are in compliance in all material respects.

applications, trademarks, trademark applications, service marks, trade names, trade secrets, inventions, copyrights, licenses and other intellectual property rights (“Intellectual Property”) and similar rights necessary or required
for use in connection with their respective businesses as described in the SEC Reports and which the failure to so have could have a Material Adverse Effect (collectively, the “Intellectual Property Rights”). Schedule 3.1(p)
is a true and complete list of registered and applied for Intellectual Property Rights owned or exclusively licensed by the Company or any Subsidiary as of the date hereof (the “Registered IP”). Except as set forth on Schedule
3.1(p), the Company or a Subsidiary is the sole and exclusive owner or licensor of the Registered IP, free and clear of all encumbrances and, the Registered IP is valid. Except as set forth on Schedule 3.1(p), neither the Company nor any

the Company nor any Subsidiary has received, since the date of the latest audited financial statements included within the SEC Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual Property Rights violate or
infringe upon the rights of any Person, except as could not have or reasonably be expected to result in a Material Adverse Effect. To the Knowledge of the Company after Due Inquiry, all such Intellectual Property Rights are enforceable, and there is
no non-academic infringement by another Person of any of the Intellectual Property Rights (including by any compound known to the Company as being under development by a third party that if commercialized would infringe such Intellectual Property
Rights). To the Knowledge of the Company after Due Inquiry, the business of the Company and its Subsidiaries does not infringe the intellectual property rights of any third party (including any such infringement that would occur in the event of
commercialization of any compound currently under development by the Company or a Subsidiary). All Employees of the Company or a Subsidiary are party to enforceable written agreements pursuant to which any Intellectual Property created by such
individuals in the course of their employment or consulting is assigned to the Company or a Subsidiary. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their
intellectual properties, except where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. The Company’s certifying officers
have evaluated the effectiveness of the disclosure controls and procedures of the Company as of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The
Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date.

capacity to execute and deliver each of the Transaction Documents to which he is a party and to perform his obligation thereunder. The Purchaser has the power and authority to enter into and to consummate the transactions contemplated by this
Agreement and otherwise to carry out its obligations hereunder and thereunder. Each Transaction 

  
 27 

 
Document to which he is a party has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof, will constitute the valid and legally binding
obligation of the Purchaser, enforceable against him in accordance with its terms, except as limited by the Enforceability Exceptions. 

(b) No Conflicts. The execution, delivery and performance of the Transaction Documents to which he is a party by the
Purchaser and the consummation by the Purchaser of the transactions contemplated thereby do not and will not: (i) violate, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse or time or both) of, any agreement, credit facility, debt or other instrument to which the Purchaser is a party or (ii) result in a
violation of any Law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Purchaser is subject (including federal and state securities Laws and regulations) or by which any
property or asset of the Purchaser is bound or affected; except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not individually or in the aggregate, reasonably be expected to
have a material adverse effect on the transactions contemplated hereby or in the other Transaction Documents or the authority or ability of the Purchaser to perform its obligations under the Transaction Documents. 

(c) Understandings or Arrangements. The Purchaser is acquiring the Shares as principal for its own account, not with a
view to the resale or distribution of any part thereof, and the Purchaser has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Shares (this representation and warranty not
limiting the Purchaser’s right to sell the Shares in compliance with applicable federal and state securities Laws). The Purchaser is acquiring the Shares hereunder in the ordinary course of its business. 

(d) Purchaser Status. At the time the Purchaser was offered the Shares, it was, and as of the date hereof it is an
“accredited investor” as defined in Rule 501(a) (5), or (a) (6) under the Securities Act. 
 (e)
Experience of the Purchaser. The Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the
prospective investment in the Shares, and has so evaluated the merits and risks of such investment. The Purchaser is able to bear the economic risk of an investment in the Shares and, at the present time, is able to afford a complete loss of such
investment. 
 (f) Access to Information. The Purchaser acknowledges that, as of the Closing Date, he has had the
opportunity to review the Transaction Documents (including all exhibits and schedules thereto) and the SEC Reports and has been afforded (i) the opportunity to ask such questions as he has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the offering of the Shares and the merits and risks of investing in the Shares; (ii) access to information about the Company and its financial condition, results of
operations, business, properties, 

  
 28 

 
management and prospects sufficient to enable him to evaluate his investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire
without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. 

(g) Disclosure. Except for the representations and warranties set forth in the Transaction Documents, the Purchaser
acknowledges and agrees that the Company is not making any representation or warranty and has not made any representation or warranty, express or implied, with respect to the Company or its Subsidiaries or their respective businesses or operations,
including with respect to any information provided or made available to the Purchaser or its representatives or to any other Person. 

(h) No General Solicitation. The Purchaser did not learn of the investment in the Shares as a result of any general
solicitation or general advertising. 
 (i) Share Ownership. Other than the Shares to be issued in connection with the
Proposed Transaction, Purchaser does not beneficially own and has not for a period of 3 years prior to the date hereof beneficially owned any Company Securities. 

(j) Restricted Securities. The Purchaser understands that the Shares have not been registered under the Securities Act
by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed
herein. The Purchaser understands that until the Shares are registered, the Shares are “restricted securities” under applicable United States federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the
Shares until they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser further acknowledges that if an exemption from registration or
qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Shares, and on requirements relating to the Company which are outside of the
Purchaser’s control. 
 (k) Legends. The Purchaser understands that the Shares and any securities issued in
respect of or exchange for the Shares, may be notated with one or all of the following legends: 
 “THE SHARES REPRESENTED HEREBY HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT
RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.” 

  
 29 

 The Company acknowledges and agrees that the representations contained in Section 3.2 shall not
modify, amend or affect the Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in the Transaction Documents.

 (b) If any action shall be
brought against a Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, a Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the

notice; (ii) deny liability in whole as to such amount; or (iii) concede liability in part and deny liability in part. If the Company and the Purchaser Party are able to resolve and agree upon any difference over said liability or the
amount thereof, then the Company agrees to make payment of said agreed amount. 
 (d) The rights of the Purchaser Parties to
indemnification or any other remedy under this Agreement shall not be impacted or limited by any knowledge that the Purchaser Parties may have acquired, or could have acquired, whether before or after the Closing Date, nor by any investigation or
diligence by the Purchaser Parties. The Company hereby acknowledges that, regardless of any investigation made (or not made) by or on behalf of the Purchaser, and regardless of the results of any such investigation, the Purchaser has entered into
this transaction in express reliance upon the representations and warranties made in the Representation Letter and by the Company in this Agreement.

or in connection with this Agreement and the Transaction Documents (including all indemnification payments required to be made to Purchaser and all amounts payable to any counsel retained by the Company for third party claims) shall be limited in
the aggregate to a maximum of $15,000,000, and the Company’s cumulative liability shall in no event exceed such amount.

approvals, clearances and authorizations of, or any exemption (collectively, “Approvals”) by all United States or foreign governmental or regulatory agency, commission, court, body, entity or authority (“Governmental
Entities”) and any third parties necessary or advisable to consummate the transactions contemplated by this Agreement; provided that the obligation set forth in this sentence shall not be deemed to have been breached as a result of
actions by the Company or its Subsidiaries permitted by Section 4.8. In particular, the Purchaser and the Company will use their best efforts to obtain, and will use their best efforts to help the others obtain, as promptly as
practicable, all other approvals, authorizations, consents, waivers, clearances, expirations or terminations of waiting periods or exemptions required from all necessary Governmental Entities and any third parties for the transactions contemplated
by the Transactions Documents. The Purchaser and the Company will have the right to review in advance and to the extent practicable each will consult with the others, in each case subject to applicable Laws relating to exchange of information, with
respect to all information relating to the parties, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions
contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and as promptly as practicable. Each party hereto agrees to keep the other parties apprised of the status of matters relating to
completion of the transactions contemplated hereby. The Purchaser and the Company shall promptly furnish each other with copies of written communications received by them or their Subsidiaries from, or delivered by any of the foregoing to, any
Governmental Entity in respect of the transactions contemplated by this Agreement or by the other Transaction Documents. Each party shall execute and deliver such further certificates, agreements and other documents and take such other actions as
the other party may reasonably request to consummate or implement such transactions or to evidence such events or matters.

public domain through no fault of such party or (iii) later lawfully acquired from other sources by the party to which it was furnished), and neither party shall release or disclose such Information to any other person, except to such
party’s auditors, attorneys, financial advisors, and other consultants and advisors. Subject to the foregoing, any party compelled to disclose Information pursuant to this Section 4.8(b) shall (A) as promptly as practicable,
provide the other parties with notice of such request to disclose Information so that the parties may seek an appropriate protective order or other appropriate remedy (and the other parties shall cooperate in connection therewith), and (B) may

 4.8. No-Shop. 

(a) From the date hereof until the Closing Date or the termination of this Agreement in accordance with Article V (the “No-Shop
Period”) neither the Company nor any of its Subsidiaries or its or their respective officers and directors shall, and the Company and its 

  
 35 

 
Subsidiaries shall not authorize any of its or their respective representatives to, directly or indirectly, (i) solicit, initiate or take any action to knowingly facilitate or knowingly
encourage the submission of any Acquisition Proposal, (ii) enter into, engage or participate in any discussions or negotiations with or furnish any non-public information relating to the Company or any of its Subsidiaries or afford access to
the business, properties, assets, books or records of the Company or any of its Subsidiaries to, any third party in connection with or for the purpose of facilitating or encouraging an Acquisition Proposal, (iii) enter into any Definitive
Transaction Agreement or (iv) grant any waiver, amendment or release under any standstill or confidentiality agreement or takeover, control share or similar Law. As of the date hereof, the Company shall, and shall cause any of its Subsidiaries
and its and their representatives to cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any third party and its representatives with respect to any Acquisition Proposal. 

(b) Notwithstanding anything to the contrary, if at any time during the No-Shop Period, (i) the Company or any of its representatives has
received a written Acquisition Proposal (which did not result from any breach of this Section 4.8) that the Board of Directors of the Company determines in good faith, after consultation with its financial advisor and outside legal
counsel, would reasonably be expected to result in a Superior Proposal and (ii) the Board of Directors of the Company determines in good faith, after consultation with outside legal counsel, that the failure to take such action would be
reasonably likely to be inconsistent with its fiduciary duties under applicable Law, then the Company, directly or indirectly through its representatives, may (A) engage in negotiations or discussions with such third party and its
representatives, (B) furnish to such third party or its representatives non-public information relating to the Company or any of its Subsidiaries; provided that the Company shall promptly provide to the Purchaser substantially
concurrently (and in any event within twenty-four (24) hours) any such information that is provided to any such Person which was not previously provided to or made available to Purchaser and (C) take any nonappealable, final action that
any court of competent jurisdiction orders the Company to take. 
 (c) Neither the Board of Directors of the Company nor any committee
thereof shall (i) (A) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Acquisition Proposal or publicly recommend any Acquisition Proposal subject to Regulation 14D under the Exchange Act in a
solicitation or recommendation statement on Schedule 14D-9 filed with respect to any such Acquisition Proposal (any action described in this clause (i), an “Adverse Recommendation Change”) or (ii) execute (or allow the Company
or any of its Subsidiaries to execute) any Definitive Transaction Agreement. Notwithstanding anything to the contrary, prior to the Closing Date, if (1) a circumstance (but specifically excluding any Acquisition Proposal) that affects the
business, assets or operations of the Company that was not known to the Company as of the date hereof becomes known by the Board of Directors of the Company after the date hereof (an “Intervening Event”), and the Board of Directors
of the Company or any committee thereof determines in good faith, after consultation with its financial advisor and outside legal counsel, that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties
under applicable Law, or (2) the Company receives an Acquisition Proposal that the Board of Directors of the Company or any committee thereof determines in good faith, after consultation with its financial advisor and outside legal counsel,
constitutes a Superior Proposal and the Board of Directors of the Company or any committee thereof determines in good faith, after consultation with its outside legal counsel and financial 

  
 36 

 
advisor, that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, the Company may (x) make an Adverse Recommendation
Change in connection with an Intervening Event or such Superior Proposal or (y) execute a Definitive Transaction Agreement; provided, however, that the Board of Directors of the Company or any committee thereof shall not,
and shall cause the Company not to, effect an Adverse Recommendation Change in connection with an Intervening Event or such Superior Proposal, or execute a Definitive Transaction Agreement and terminate this Agreement with respect to such Superior
Proposal unless (w) the Company has given the Purchaser at least three (3) Business Days’ prior written notice of its intention to take such action (which notice shall, in the event of a Superior Proposal, specify the identity of the
party making such Superior Proposal and attach the most current version of the proposed agreement under which such Superior Proposal is proposed to be consummated, and in the event of an Intervening Event, provide a detailed description of such
Intervening Event), (x) the Company has negotiated, and has caused its representatives to negotiate, in good faith with the Purchaser during such notice period, to the extent the Purchaser wishes to negotiate, to enable the Purchaser to propose
in writing revisions to the terms of this Agreement, which revisions shall be evidenced by an offer to amend this Agreement that would, upon the Company’s acceptance, be binding on the Company and the Purchaser, such that such Superior Proposal
would no longer constitute a Superior Proposal or the failure to make an Adverse Recommendation Change with respect to such Intervening Event would no longer be inconsistent with its fiduciary duties under applicable Law, (y) following the end
of such notice period, the Board of Directors of the Company or any committee thereof shall have considered in good faith such binding offer, and shall have determined that the Superior Proposal would continue to constitute a Superior Proposal or
the failure to make an Adverse Recommendation Change with respect to such Intervening Event would continue to be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, if the revisions proposed in such binding offer
were to be given effect and (z) in the event of any material change to the material terms of such Superior Proposal, the Company shall, in each case, have delivered to the Purchaser an additional notice consistent with that described in clause
(w) above and the notice period shall have recommenced, except that the notice period shall be at least three calendar days (rather than the three (3) Business Days otherwise contemplated by clause (w) above); and
provided, further, however, that any purported termination of this Agreement pursuant to this sentence shall be void and of no force or effect, unless the Company pays the Termination Fee pursuant to
Section 6.1. In addition, nothing contained in this Agreement shall prevent the Company or the Board of Directors of the Company from (i) making any disclosure to its stockholders with regard to the transactions contemplated by this
Agreement or an Acquisition Proposal, which the Board of Directors of the Company has determined in good faith, after consultation with outside legal counsel, that the failure to do so would be reasonably likely to be inconsistent with the
directors’ fiduciary duties under applicable Law (provided that neither the Company nor its Board of Directors may enter into a Definitive Transaction Agreement with respect to such Acquisition Proposal unless permitted by this
Section 4.8), or (ii) contacting and engaging in discussions with any Person or group and their respective representatives who has made an Acquisition Proposal solely for the purpose of clarifying such Acquisition Proposal and the
terms thereof. 
 (d) The Company shall promptly (and in any event, within twenty-four (24) hours) notify the Purchaser after receipt
by the Company or any of its Subsidiaries (or any of its or their representatives) of any Acquisition Proposal or any request for information relating to the 

  
 37 

 
Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries by any third party that the Company knows is
considering making, or has made, an Acquisition Proposal, which notice shall include the material terms and conditions of any such Acquisition Proposal, indication or request (including, if applicable, copies of any written requests, proposals or
offers, including any proposed Definitive Transaction Agreement) and the identity of the third party or group of third parties making such Acquisition Proposal, and the Company shall keep the Purchaser reasonably informed on a prompt basis of any
material developments, discussions or negotiations with respect to any such Acquisition Proposal (including any material changes to such Acquisition Proposals) and shall provide copies of all correspondence and other written materials sent or
provided to the Company or any of its representatives relating to such material developments, discussions or negotiations promptly upon receipt thereof, and in any event within twenty-four (24) hours. The Company shall not, and shall cause its
Subsidiaries not to, enter into any confidentiality or similar agreement with any Person that prohibits the Company from providing to the Purchaser any of the information required to be provided to the Purchaser within the time periods contemplated
hereby. 
 4.9. Governance Matters. 

(a) At or prior to the Closing Date, with an effective date as of the Closing Date, pursuant to Article III, Section 2 of the
Company’s Bylaws, the Board of Directors shall increase the size of the Board of Directors to thirteen (13) members. Pursuant to Article SEVENTH, Section (c) of the Certificate of Incorporation of the Company, the Board of Directors
shall appoint as directors the seven individuals designated by the Purchaser (the “Board Designees”) as directors to fill the newly created directorships, subject to satisfaction of all legal and governance requirements regarding
service as a director of the Company. 
 (b) From and after the Closing Date and for so long as Purchaser beneficially owns at least a
majority of the Company’s issued and outstanding Common Stock, Purchaser shall be entitled to nominate to the Board of Directors a number of designees (the “Board Representatives”) equal to at least a majority of the total
number or directors which then constitute the Board of Directors. Unless the Board of Directors determines in good faith, after consultation with outside counsel, that such action would be reasonably likely to be inconsistent with its fiduciary
duties under applicable Law, the Company shall recommend to its stockholders the Board Representatives for election to the Board of Directors at the Company’s stockholder meetings. 

(c) In addition, the Company agrees that the Board Representatives (including its initial Board Designees) shall be entitled to the same
rights, privileges and compensation as the other members of the Board of Directors in their capacity as such, including with respect to insurance coverage and reimbursement for Board of Directors participation and related expenses. 

(d) Subject to the further provisions of this Section 4.9, and unless the Company’s Governance and Nominating Committee (or
any other committee exercising a similar function) (the “Nominating Committee”) determines in good faith, after consultation with outside counsel, that such action would be reasonably likely to be inconsistent with its fiduciary
duties under applicable Law, the Nominating Committee shall recommend to the Board of Directors that such 

  
 38 

 
persons designated by the Purchaser to be Board Representatives pursuant to Section 4.9(b) (or any successor designated by the Purchaser) be included in the slate of nominees
recommended by the Board of Directors to stockholders for election as directors at each annual meeting of stockholders of the Company at which such person’s term expires. Unless the Board of Directors determines in good faith, after
consultation with outside counsel, that such action would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, the Company shall solicit proxies for them to the same extent as it does for any of its other nominees
to the Board of Directors. 
 (e) At any time the Purchaser has a right to nominate one or more individuals to the Board of Directors to
serve as a director, if any Board Representative shall cease to serve as a director for any reason, unless the Board of Directors determines in good faith, after consultation with outside counsel, that such action would be reasonably likely to be
inconsistent with its fiduciary duties under applicable Law, the Company and its Board of Directors shall take all action required to fill the vacancy resulting therefrom with a person designated by the Purchaser (the “Replacement
Designee”). If the Company does not accept a Replacement Designee as provided in this Section 4.10(e), the process set forth herein shall be repeated so long as necessary to find a Replacement Designee acceptable to the Company. 

(f) Additionally, promptly following the Closing Date, the Company and its Board of Directors shall use their best efforts to take all
necessary actions in order to cause the Restated Certificate of Incorporation of the Company to be amended at the Company’s next annual meeting of its stockholders or a special meeting of the stockholders (but in any event, within twelve
(12) months of the Closing Date) to (collectively, the “Amendments”): 
 (i) provide that any director
or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of director; 

(ii) provide that any holder of 10% or more of the outstanding Common Stock shall be entitled to call a special meeting of the
stockholders; 
 (iii) expressly elect that Section 203 of the DGCL shall not apply. 

In connection with the solicitation of proxies in favor of approval of the Amendments, the Company shall enter into an agreement with, and employ the services
of, a proxy solicitor. Unless the Board of Directors determines in good faith, after consultation with outside counsel, that such action would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, the Board of
Directors shall recommend the approval of the Amendments and such recommendation shall be included in each proxy statement filed with the SEC and disseminated to Company stockholders in connection with the stockholder meeting. In the event that the
Amendments are not approved at the meeting of the stockholders at which the approval of the Amendments is sought, at the Purchaser’s request, the Company shall call and convene one or more subsequent meetings of the stockholders for the purpose
of obtaining approval of the Amendments until obtained and, unless the Board of Directors determines in good faith, after consultation with outside counsel, that such action would be reasonably likely to be inconsistent with its fiduciary duties
under applicable Law, the Board of Directors shall recommend the 

  
 39 

 
approval of the Amendments at each subsequent meeting, and such recommendation shall be included in each proxy statement filed with the SEC and disseminated to Company stockholders in connection
with any additional stockholder meeting. 
 4.10. Certain Transfer Restrictions. 

(a) In connection with any registration of the Shares, without the prior written consent of the Company and the managing
underwriter, the Purchaser shall not (except to an Affiliate of Purchaser) (i) lend; 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, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock held immediately before the effective date
of the registration statement for such offering or (ii) enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities or has the same economic
effect as a sale, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise, any Common Stock (or other securities) of the Company held by the
Purchaser (other than those included in the registration) during the one hundred eighty (180) day period following the effective date of a registration statement of the Company filed under the Securities Act (or such other period as may be
requested by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions), provided that all officers and
directors of the Company are bound by and have entered into similar agreements. 
 (b) During the period from the Closing
Date until the second anniversary of the Closing Date, the Purchaser shall not (other than to an Affiliate of the Purchaser who agrees to be bound by the terms hereof) sell or otherwise transfer any of the Shares. 

4.11. Equity Grants. From the Closing Date until the 12 month anniversary of the Closing Date, the Company shall not, and shall cause
its Subsidiaries not to, (a) issue, deliver or sell, or authorize the issuance, delivery or sale of, any shares of any Company Securities, other than the issuance of (i) any shares of the Common Stock upon the exercise or conversion of any
Company Stock Options, Company Warrants or Preferred Stock issued and outstanding as of the date hereof and solely in accordance with the terms of such Company Stock Options, Company Warrants or Preferred Stock, as applicable, or (ii) any
Company Securities to the Company or any Subsidiary of the Company, or (b) amend any term of any Company Security, (c) grant or increase, or agree to grant or increase, any stock options, or any other equity-based awards to any
“Eligible Individual” as such term is defined in the Approved Share Plan whether pursuant to the terms of the Approved Share Plan or otherwise or (d) allow or approve the commencement of an “Offering” or any
other issuance of stock under the terms of the Company’s 2013 Employee Stock Purchase Plan, as amended, in each case, except with the prior approval of the Board of Directors (or authorized committee thereof). 

  
 40 

 4.12. Application of Takeover Protections. From and after, the Closing Date, at the
written request of the Purchaser and unless the Board of Directors determines in good faith, after consultation with outside counsel, that such action would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, the
Company and the Board of Directors shall take all necessary action, if any, in order to render inapplicable any control share acquisition, interested stockholder, business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents) or the Laws of its state of incorporation that is or could become applicable in connection with any transaction
that involves a transfer by the Purchaser and/or its Affiliates of all or any portion of the Shares to any other Person who is not an Affiliate of the Purchaser. 

4.13. Registration of Shares. The Company agrees to register the Shares for resale under the Securities Act in accordance with the
Registration Rights Agreement, and the Company agrees to use its reasonable best efforts to maintain the continuous effectiveness of such registration statement until all of the Shares are sold. Notwithstanding anything to the contrary contained in
the Registration Rights Agreement, the Company shall cause all of the Shares to be registered pursuant to one or more effective registration statements within 120 days of the initial request by the Purchaser and/or its permitted assigns to so
register all of the Shares, which request shall not be made until after the first anniversary of the Closing Date. 
 4.14.
Insurance. The Company agrees that is has not, and will not, insure, pay or otherwise be obligated to pay any of the obligations of either of the Key Employees party to the Representation Letter arising out of a breach of any of such Key
Employees’ representations, warranties or obligations under such Representation Letter.

taken any other action restraining or otherwise prohibiting the Proposed Transaction and such order, decree, ruling or other action shall have become final and non-appealable; 

(ii) if the Closing shall not have occurred by the Outside Date; provided that the party seeking to terminate this Agreement

 41 

 (c) by Purchaser:

the Outside Date; or 
 (d) by the Company: 

(i) if a breach of any representation or warranty or failure to perform any covenant or agreement on the Purchaser set forth in this
Agreement shall have occurred and such breach would cause the conditions set forth in Section 2.3(a) not to be satisfied, and such breach is incapable of being satisfied by the Outside Date or, if curable, is not cured by the Purchaser
prior to the Outside Date; or 
 (ii) if (A) all of the conditions set forth in Article 2 have been satisfied or waived (other than
those conditions that by their terms are to be satisfied at the Closing), (B) the Purchaser fails to consummate the Proposed Transaction within two (2) Business Days following the date the Closing should have occurred pursuant to
Section 2.1, and (C) the Company provided written notice to the Purchaser that it was ready and willing to consummate the Closing during such period; provided however that during such period of two (2) Business Days

5.2. Notice. Any party terminating this Agreement pursuant to this Section shall give written notice of such termination to the other
parties in accordance with this Agreement, specifying the provision or provisions hereof pursuant to which such termination is being effected. In the event of the termination and abandonment of this Agreement pursuant to Section 5.1,

Article VI shall survive such termination. 

  
 42

Section 5.1, this Agreement shall become void and of no effect without liability of any party (or any stockholder, director, officer, employee, agent, consultant or representative of such party) to the other parties; provided
that, subject to Sections 6.1 and 6.16, no such termination shall relieve any party of any liability for damages (which the parties acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs)
incurred or suffered by the other party resulting from gross negligence, fraud, willful misconduct or intentional breach of this Agreement.

“Inventions”). The Executive further acknowledges that all original works of authorship which are made by the Executive (solely or jointly with others) within the scope of and during the period of his employment with the

Company. The records will be available to and remain the sole property of the Company at all times. 
 (v) Patent and Copy
Registrations. The Executive agrees to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions and any copyrights, patents, mask work rights or other
intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, declarations, oaths,
assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title
and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto. The Executive further agrees that the Executive’s obligation to execute or cause to be executed, when
it is in his power to do so, any such instrument or papers shall continue after the termination of this Agreement. If the Company is unable because of the Executive’s mental or physical incapacity or for any other reason to secure his signature
to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then the Executive hereby irrevocably designates and
appoints the Company and its duly authorized officers and agents as the Executive’s agent and attorney in fact, to act for and in the Executive’s behalf and stead to execute and file any such applications and to do all other lawfully
permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by the Executive. Such designation and appointment, being coupled with an interest, is
irrevocable. 
 (c) NON-SOLICITATION AND NON-COMPETITION. 

(i) Solicitation of Employees, Consultants, Contractors and Customers. The Executive agrees that for a period of twenty-four
(24) months immediately following the termination of the Executive’s relationship with the Company for any reason, whether with or without cause, the Executive shall not either directly or indirectly solicit, induce, recruit or encourage
any of the Company’s employees, consultants, contractors or customers to terminate his or her relationship with the Company, or take away such employees, consultants, contractors or customers or attempt to solicit, induce, recruit, encourage or
take away employees, consultants or contractors of the Company, either for the Executive or for any other person or entity; provided however, the Executive may hire any employee, consultant or contractor of the Company who independently
responds to a general solicitation of employment. This restriction 

  
 6 

 
shall apply only to those employees, consultants, contractors or customers of the Company with whom the Executive came into contact or about whom the Executive learned Confidential Information
during the last two (2) years of the Executive’s employment with the Company. Notwithstanding the foregoing, this provision does not prohibit the solicitation of United States federal, state or foreign government agency, including but not
limited to United States Department of Defense. 
 (ii) Non-Competition. The Executive agrees that during the period of employment
and for a period of twenty-four (24) months immediately following the termination of the Executive’s relationship with the Company for any reason, the Executive shall not directly or indirectly own, manage, operate, consult or be employed
in a business substantially similar to, or competitive with, the Company’s Business (as defined below) and the business of its successors and assigns or any other business activity in which the Company and its successors and assigns may
substantially engage during the Employment Term. In recognition of the nature of the Company’s Business, which includes the sale of its products and services on an international basis, this restriction shall apply throughout the United States,
Russia and in any country or territory in which the Company materially markets any of its products or services, or to the knowledge of the Executive, plans to beginning marketing any of its products or services. For purposes of this Agreement, the
“Company’s Business” shall include any product, service, or process or the research and development thereof, of the Company with which the Executive worked directly or indirectly during the Executive’s employment by
the Company or about which the Executive acquired Confidential Information during the Executive’s employment by the Company, including but not limited to the research and development of new pharmaceuticals as defined by the Company’s
therapeutic area and core technology. Notwithstanding the foregoing, nothing in this Agreement shall prevent the Executive from engaging in a scientific, consulting or other business capacity in research and development of pharmaceuticals to treat
cancer or other diseases if such research and development does not use any Confidential Information of the Company. 
 (d) ADDITIONAL
COMPANY POLICIES. The Executive agrees to comply with the Company’s Policy Manual and each of the other policies adopted by the Company from time-to-time, the contents of which may be modified or eliminated at any time. 

(e) NOTIFICATION OF NEW EMPLOYER. In the event that the Executive leaves the employ of the Company, the Executive hereby grants consent
to notification by the Company to the new employer, partner, co-owner and/or others involved in managing the business with which the Executive is employed or associated about the obligations under this Agreement. 

(f) ENFORCEMENT. The Executive acknowledges and agrees that compliance with the covenants set forth in this Agreement is necessary to
protect the Confidential Information and trade secrets, business and goodwill of the Company, and that any breach of this Agreement will result in irreparable and continuing harm to the Company, for which money damages may not provide adequate
relief. Accordingly, in the event of any breach or anticipatory breach of this Agreement by the Executive, or the Executive’s claim in a declaratory judgment action that all or part of this Agreement is unenforceable, the parties agree that the
Company shall be entitled to (i) injunctions, both preliminary and permanent, enjoining or restraining such breach or anticipatory breach, and the Executive hereby consents to the issuance thereof forthwith and without bond by any court of competent
jurisdiction; and (ii) recovery of all reasonable sums and costs, including attorney’s fees, incurred by the Company to defend or enforce the provision of this Agreement.

 10. TERMINATION. The Executive’s employment and the Employment Term shall
terminate on the first of the following to occur: 
 (a) BY THE EXECUTIVE FOR ANY REASON // WITHOUT GOOD REASON. The Executive shall
provide thirty (30) days’ prior written notice (the “Transition Period”) to the Company of the Executive’s intended termination of employment without Good Reason (as defined below) (“Voluntary
Termination”). During the Transition Period, the Executive shall assist and advise the Company in any transition of business, customers, prospects, projects and strategic planning, and the Company shall continue to pay the
Executive’s salary and benefits through the end of the Transition Period. The Company may, in its sole discretion, upon five (5) days prior written notice to the Executive, make such termination of employment effective earlier than the
expiration of the Transition Period and the Company shall have no further obligation to pay the Executive’s salary or benefits after such termination date. 

(b) BY THE EXECUTIVE FOR GOOD REASON. Upon the Executive’s notice following the end of the Cure Period (as defined in this
Section). For purposes of this Agreement, “Good Reason” for the Executive to terminate employment hereunder shall mean the occurrence of any of the following events without the Executive’s consent: (i) a material reduction
of ten percent (10%) or more in the Executive’s Base Salary (other than an across-the-board decrease in base salary applicable to all executive officers of the Company); (ii) a material breach of this Agreement by the Company;
(iii) a material reduction in the Executive’s duties, authority and responsibilities relative to the Executive’s duties, authority, and responsibilities in effect immediately prior to such reduction; or (iv) the relocation of the
Company’s headquarters outside the United States, or if within the United States causing an increase in the Executive’s one-way commute by more than 50 miles or a material change in the Company’s telecommuting policies and practices,
provided, however, that, any such termination by the Executive shall only be deemed for Good Reason pursuant to this definition if: (1) the Executive gives the Company written notice of the Executive’s intent to terminate for Good
Reason within thirty (30) days following the first occurrence of the condition(s) that the Executive believes constitute(s) Good Reason, which notice shall describe such condition(s); (2) the Company fails to remedy such condition(s)
within thirty (30) days following receipt of the written notice (the “Cure Period”); and (3) the Executive voluntarily terminates employment within thirty (30) days following the end of the Cure Period. 

(c) BY THE COMPANY FOR CAUSE. Immediately upon written notice by the Company to the Executive of a termination for Cause. For purposes
of this Agreement, “Cause” shall mean the occurrence of any of the following events, as determined by the Board in its sole and absolute discretion: (i) the failure of the Executive to perform material duties hereunder,
including, without limitation, the failure of the Executive devote [all OR at least         %] of the Executive’s business time (excluding periods of paid time off and other approved leaves of absence) to
the performance of the Executive’s duties with the Company, or comply with reasonable directions of the Board which, to the extent it is curable by the Executive, is not cured within ten (10) days after written notice thereof is given to
the Executive 

  
 8 

 
by the Company, specifying in reasonable detail the manner in which the Executive has failed to perform such duties or comply with such directions; (ii) the Executive’s commission
(including entry of a nolo contendere plea) of an act or acts constituting a felony, dishonesty or disloyalty or fraud; (iii) the Executive’s gross negligence or commission of an act, or failure to take action, which adversely
affects the Company’s business or reputation; (iv) the Executive’s misappropriation or embezzlement of the property of the Company or its affiliates (whether or not a misdemeanor or felony); or (v) the Executive’s material
breach, non-performance or non-observance of any Company policy or any term of this Agreement, including but not limited to the covenants contained in Section 9, or any other agreement to which the Executive and the Company are parties, which,
to the extent it is curable by the Executive, is not cured within ten (10) days after written notice thereof is given to the Executive by the Company. 

(d) BY THE COMPANY WITHOUT CAUSE. Upon written notice by the Company to the Executive of an involuntary termination without Cause and
other than due to death or Disability. 
 (e) DISABILITY. Unless otherwise prohibited by law, upon the 30th day following the Executive’s receipt of notice of the Company’s termination due to Disability (as defined in this Section); provided that, the Executive has not returned to
full-time performance of his duties within thirty (30) days after receipt of such notice. If the Company determines in good faith and in its sole discretion that the Executive’s Disability has occurred during the Employment Term, it will
give the Executive written notice of its intention to terminate the Executive’s employment. For purposes of this Agreement, “Disability” shall occur when the Board determines that the Executive has become physically
or mentally incapable of performing the essential functions of the job duties under this Agreement with or without reasonable accommodation, for ninety (90) consecutive days or one hundred twenty (120) nonconsecutive days in any twelve
(12) month period. For purposes of this Section, at the Company’s request, the Executive agrees to be available and to cooperate in a reasonable examination by an independent qualified physician selected by the Board. 

(f) DEATH. Automatically on the date of death of the Executive. 

11. CONSEQUENCES OF TERMINATION. Any termination payments made and benefits provided under this Agreement to the Executive shall
be in lieu of any termination or severance payments or benefits for which the Executive may be eligible under any of the plans, policies or programs of the Company or its affiliates as may be in effect from time to time. Subject to satisfaction of
each of the conditions set forth in Section 12, the following amounts and benefits shall be due to the Executive. Any Accrued Amounts (as defined in Section 11(a)) shall be payable on the next regularly scheduled Company payroll date
following the date of termination or earlier if required by applicable law. 
 (a) TERMINATION BY THE COMPANY FOR CAUSE OR BY THE
EXECUTIVE FOR ANY REASON // WITHOUT GOOD REASON. If the Executive’s employment should be terminated (i) by the Company for Cause, or (ii) by the Executive for any reason // without Good Reason, the Company shall pay to the
Executive: (x) any unpaid Base Salary through the date of termination and any accrued PTO; (y) reimbursement for any unreimbursed expenses incurred through the date of termination; and (z) all other payments and

  
 9 

 
benefits to which the Executive may be entitled under the terms of any applicable compensation arrangement or benefit, equity or perquisite plan or program or grant or this Agreement, including
but not limited to any applicable insurance benefits, it being understood that the treatment of any outstanding stock options shall be determined in accordance with the terms of the applicable equity plan and award agreement (collectively,
“Accrued Amounts”) only, and shall not be obligated to make any additional payments to the Executive. For the avoidance of doubt, the Executive shall not be eligible to receive any of the severance payments or benefits
described in Section 11(b). 
 (b) TERMINATION BY THE COMPANY WITHOUT CAUSE OR BY THE EXECUTIVE FOR GOOD REASON. If the
Executive’s employment by the Company is terminated by the Company without Cause (and not due to Disability or death) or by the Executive for Good Reason, then the Company shall pay or provide the Executive with the Accrued Amounts, subject to
compliance with Sections 9 and 12, and: 
 (i) continued payment of the Executive’s Base Salary as in effect immediately preceding the
last day of the Employment Term (ignoring any decrease in Base Salary that forms the basis for Good Reason), for a period of twelve (12) months following the termination date (the “Salary Severance Period”) on the
Company’s regular payroll dates; provided, however, that any payments otherwise scheduled to be made prior to the effective date of the General Release (namely, the date it can no longer be revoked) shall accrue and be paid in the first
payroll date that follows such effective date with subsequent payments occurring on each subsequent Company payroll date; and 
 (ii) if
the Executive timely elects continued coverage under COBRA for the Executive and the Executive’s covered dependents under the Company’s group health plans following such termination, then the Company shall pay the COBRA premiums necessary
to continue the Executive’s and the Executive’s covered dependents’ health insurance coverage in effect on the termination date until the earliest of (i) twelve (12) months following the termination date (the
“COBRA Severance Period”); (ii) the date when the Executive becomes eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment; or (iii) the date the
Executive ceases to be eligible for COBRA continuation coverage for any reason, including plan termination (such period from the termination date through the earlier of (i)-(iii), the “COBRA Payment Period”). Notwithstanding
the foregoing, if at any time the Company determines that its payment of COBRA premiums on the Executive’s behalf would result in a violation of applicable law (including but not limited to the 2010 Patient Protection and Affordable Care Act,
as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of paying COBRA premiums pursuant to this Section, the Company shall pay the Executive on the last day of each remaining month of the COBRA Payment Period, a fully
taxable cash payment equal to the COBRA premium for such month, subject to applicable tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to the
Executive’s payment of COBRA premiums and without regard to the expiration of the COBRA period prior to the end of the COBRA Payment Period. Nothing in this Agreement shall deprive the Executive of the Executive’s rights under COBRA or
ERISA for benefits under plans and policies arising under the Executive’s employment by the Company. 

  
 10 

 (iii) all issued and outstanding options will continue to vest according to their established
schedules throughout the Salary Severance Period, and all vested options will remain exercisable throughout the Salary Severance Period, but in no event later than the expiration date of the options. 

(c) DISABILITY. Upon employment termination due to Disability, the Executive shall be entitled to any Accrued Amounts. 

(d) DEATH. In the event the Employment Term ends on account of the Executive’s death, the Executive’s estate (or to the
extent a beneficiary has been designated in accordance with a program, the beneficiary under such program) shall be entitled to any Accrued Amounts. 

(e) TERMINATION BY THE COMPANY WITHOUT CAUSE OR BY THE EXECUTIVE FOR GOOD REASON FOLLOWING A CHANGE IN CONTROL. 

(i) If the Executive’s employment by the Company is terminated by the Company without Cause (and not due to Disability or death) or by
the Executive for Good Reason within twelve (12) months following a Change in Control (as defined in the Equity Plan), then the Company shall pay or provide the Executive with the Accrued Amounts and all of the benefits described in
Section 11(b) above, subject to compliance with Sections 9 and 12, with the exception that Section 11(b) (iii) shall read: all issued and outstanding options will become immediately vested and will remain exercisable through the
Salary Severance Period, but in no event later than the expiration date of the options. Notwithstanding anything to the contrary, the Executive agrees and acknowledges that the transactions contemplated under the Securities Purchase Agreement shall
not be considered a “Change in Control” for purposes of this Section 11(e). 
 12. CONDITIONS. Any payments or
benefits made or provided pursuant to Section 11 (other than Accrued Amounts) are subject to the Executive’s (or, in the event of the Executive’s death, the beneficiary’s or estate’s, or in the event of the Executive’s
Disability, the guardian’s if applicable): 
 (a) compliance with the provisions of Section 9 of this Agreement; 

(b) delivery to the Company of an executed waiver and general release of any and all known and unknown claims, and other provisions and
covenants, in the form acceptable to the Company (the “General Release”) within 21 days of presentation thereof by the Company to the Executive, and permitting the General Release to become effective in accordance with its
terms; and 
 (c) delivery to the Company of a resignation from all offices, directorships and fiduciary positions with the Company, its
affiliates and employee benefit plans effective as of the termination date. 
 Notwithstanding the due date of any post-employment payments,
any amounts due following a termination under this Agreement (other than Accrued Amounts) shall not be due until after the expiration of any revocation period applicable to the General Release without the

  
 11 

 
Executive having revoked such General Release, and any such amounts shall be paid or commence being paid to the Executive within fifteen (15) days of the expiration of such revocation period
without the occurrence of a revocation by the Executive (or such later date as may be required under Section 19 of this Agreement). Nevertheless (and regardless of whether the General Release has been executed by the Executive), upon any
termination of Executive’s employment, Executive shall be entitled to receive any Accrued Amounts, payable after the date of termination in accordance with the Company’s applicable plan, program, policy or payroll procedures.
Notwithstanding anything to the contrary in this Agreement, if any severance pay or benefits are deferred compensation under Section 409A (as defined below), and the period during which the Executive may sign the General Release begins in one
calendar year and the first payroll date following the period during which the Executive may sign the General Release occurs in the following calendar year, then the severance pay or benefit shall not be paid or the first payment shall not occur
until the later calendar year. 
 13. ASSIGNMENT. This Agreement shall be binding upon and inure to the benefit of the
Executive and the Executive’s heirs, executors, personal representatives, assigns, administrators and legal representatives. Because of the unique and personal nature of the Executive’s duties under this Agreement, neither this Agreement
nor any rights or obligations under this Agreement shall be assignable by the Executive. This Agreement shall be binding upon and inure to the benefit of the Company and its successors, assigns and legal representatives. Any such successor or assign
of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose, “successor” means any person, firm, corporation or other business entity which at any time, whether by
purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company. 
 14.

or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be
effective only upon receipt. 
 15. SECTION HEADINGS; INCONSISTENCY. The section headings used in this Agreement are included
solely for convenience and shall not affect, or be used in connection with, the interpretation of this Agreement. If there is any inconsistency between this Agreement and any other agreement (including but not limited to any option, stock, long-term
incentive or other equity award agreement), plan, program, policy or practice (collectively, “Other Provision”) of the Company the terms of this Agreement shall control over such Other Provision. 

16. SEVERABILITY. The provisions of this Agreement shall be deemed severable and the invalidity of unenforceability of any
provision shall not affect the validity or enforceability of the other provisions hereof. In case any one or more of the provisions, subsections, or sentences contained in this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been
contained in this Agreement. If moreover, any one or more of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting
and reducing it, so as to be enforceable to the extent compatible with the applicable law as it shall then appear. 
 17.
COUNTERPARTS. This Agreement may be executed in counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instruments. One or more counterparts of this Agreement may be
delivered by facsimile, with the intention that delivery by such means shall have the same effect as delivery of an original counterpart thereof. 

18. SECTION 4999 EXCISE TAX. 

(a) Notwithstanding anything in this Agreement or any other agreement between the Executive and the Company (or any of its subsidiaries or
affiliates) to the contrary, in the event that the provisions of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) relating to “parachute payments” (as defined in the Code) shall be
applicable to any payment or benefit received or to be received by the Executive from the 

  
 13 

 
Company or its affiliates in connection with a change in the ownership or effective control of the Company within the meaning of Section 280G of the Code (a “Change in Control
Transaction”) (collectively, “Payments”), then (a) at the Executive’s request, the Company agrees to submit such Payments to a shareholder vote intended to comply with the provisions of
Section 280G(b)(5) of the Code, or (b) in the event that the Executive does not request a shareholder vote as set forth above or the provisions of Section 280G(b)(5) are inapplicable to the Company, then any such Payments shall be
equal to the “Reduced Amount” where the Reduced Amount is (1) the largest portion of the Payments that will result in no portion of such Payments being subject to the excise tax imposed by Section 4999 of the Code,
or (2) the entire amount of the Payments otherwise scheduled to be paid (without reduction), whichever of the forgoing amounts after taking into account all applicable federal, state and local employment taxes, income taxes and the excise tax
of Section 4999 of the Code (all computed at the highest applicable merged rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of all state and local taxes), results in the Executive’s
receipt, on an after-tax basis, of the greatest amount of Payments. If subsection (1) above applies and a reduced amount of the Payments is payable, then any reduction of Payments required by such provision shall occur in the following order:
(i) first, a reduction of any Payments that are exempt from Section 409A in a manner the Company reasonably determines will provide the Executive with the greatest post-reduction economic benefit, and (ii) second, a reduction of any
Payments that are subject to Section 409A on a pro-rata basis or such other manner that complies with Section 409A, as reasonably determined by the Company. 

(b) In connection with a Change in Control Transaction, the Company shall engage a certified public accounting firm
(“Accountants”) to perform the calculations to determine if the Payments to the Executive would reasonably be subject to Section 280G of the Code, and the Company shall use commercially reasonable efforts to
(1) cause the Accountants to finalize such calculations and (2) deliver such calculations and supporting documentation to the Executive, by no later than five (5) days before the closing of the Change in Control Transaction. If the
Executive, in good faith, disagrees with or disputes any of the assumptions, findings or determinations of the Accountants in respect of such calculations, the Company shall use reasonable efforts to cause its Accountants to consider in good faith
the Executive’s position and revise such calculations if the Accountants determine that it is more-likely-than-not, based on the technical merits, that the Executive’s position will be sustained upon examination by the Internal Revenue
Service. 
 19. SECTION 409A. 

(a) Notwithstanding anything to the contrary herein, the following provisions apply to the extent severance benefits provided herein are
subject to Section 409A of the Code and the regulations and other guidance thereunder and any state law of similar effect (collectively “Section 409A”). Severance benefits shall not commence until Executive has a
“separation from service” (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “separation from service”). Each installment of severance benefits is a separate
“payment” for purposes of Treas. Reg. Section 1.409A-2(b)(2)(i), and the severance benefits are intended to satisfy the exemptions from application of Section 409A provided under Treasury Regulations Sections 1.409A-1(b)(4),
1.409A-1(b)(5) and 1.409A-1(b)(9). However, if such exemptions are not available and Executive is, upon 

  
 14 

 
separation from service, a “specified employee” for purposes of Section 409A, then, solely to the extent necessary to avoid adverse personal tax consequences under
Section 409A, the timing of the severance benefits payments shall be delayed until the earlier of (i) six (6) months and one day after Executive’s separation from service, or (ii) Executive’s death. The parties
acknowledge that the exemptions from application of Section 409A to severance benefits are fact specific, and any later amendment of this Agreement to alter the timing, amount or conditions that will trigger payment of severance benefits may
preclude the ability of severance benefits provided under this Agreement to qualify for an exemption. 
 (b) It is intended that this
Agreement shall comply with the requirements of Section 409A, and any ambiguity contained herein shall be interpreted in such manner so as to avoid adverse personal tax consequences under Section 409A. Notwithstanding the foregoing, the
Company shall in no event be obligated to indemnify the Executive for any taxes or interest that may be assessed by the Internal Revenue Service pursuant to Section 409A of the Code to payments made pursuant to this Agreement. To the extent
that any severance benefit payments are delayed as required by this Agreement due to the application of Section 409A. 
 20.
REPRESENTATIONS. The Executive represents and warrants to the Company that the Executive has the legal right to enter into this Agreement and to perform all of the obligations on the Executive’s part to be performed hereunder in
accordance with its terms and that the Executive is not a party to any agreement or understanding, written or oral, which could prevent the Executive from entering into this Agreement or performing all of the Executive’s obligations hereunder.
The Executive further represents and warrants that he has been advised to consult with an attorney and that he has been represented by the attorney of his choosing during the negotiation of this Agreement, that he has consulted with his attorney
before executing this Agreement, that he has carefully read and fully understand all of the provisions of this Agreement and that he is voluntarily entering into this Agreement. 

21. WITHHOLDING. The Company may withhold from any and all amounts payable under this Agreement such federal, state and local
taxes as may be required to be withheld pursuant to any applicable law or regulation. 
 22. SURVIVAL. The respective
obligations of, and benefits afforded to, the Company and the Executive which by their express terms or clear intent survive termination of the Executive’s employment with the Company, including, without limitation, the provisions of Sections 9
through 27, inclusive of this Agreement, will survive termination of the Executive’s employment with the Company, and will remain in full force and effect according to their terms. 

23. AGREEMENT OF THE PARTIES. The language used in this Agreement will be deemed to be the language chosen by the parties hereto
to express their mutual intent, and no rule of strict construction will be applied against any party hereto. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement. Neither the Executive nor the Company shall be entitled to any presumption in connection with any determination made hereunder in connection with any arbitration, judicial or administrative
proceeding relating to or arising under this Agreement. 

  
 15 

 24. INTEGRATION. This Agreement contains the complete, final and exclusive
agreement of the parties relating to the terms and conditions of the Executive’s employment and the termination of the Executive’s employment, and supersedes all prior and contemporaneous oral and written employment agreements or
arrangements between the parties[, including but not limited to the [INSERT NAMES OF ANY PERTINENT AGREEMENTS. If any obligations in those agreements should be preserved, include an exception for those obligations.]. 

25. AMENDMENT. This Agreement cannot be amended or modified except by a written agreement signed by the Executive and a duly
authorized officer of the Company, who has been authorized to do so by a decision of the Board of Directors of the Company. 
 26.
WAIVER. No term, covenant or condition of this Agreement or any breach thereof shall be deemed waived, except with the written consent of the party against whom the wavier is claimed, and any waiver or any such term, covenant,
condition or breach shall not be deemed to be a waiver of any preceding or succeeding breach of the same or any other term, covenant, condition or breach. 

27. CHOICE OF LAW. This Agreement shall be construed and interpreted in accordance with the internal laws of the State of
New York without regard to its conflict of laws principles. 
 28. DISPUTE RESOLUTION. To ensure the rapid and economical
resolution of disputes that may arise in connection with the Executive’s employment with the Company, the Executive and the Company agree that any and all disputes, claims, or causes of action, in law or equity shall be resolved, to the fullest
extent permitted by law, by final, binding and confidential arbitration in Buffalo, New York conducted by JAMS, Inc. (“JAMS”) or its successor, under JAMS’ then applicable rules and procedures for employment disputes,
which can be found at HTTP://WWW.JAMSADR.COM/RULES-CLAUSES/, and which will be provided to the Executive upon request. By agreeing to this
arbitration procedure, both the Executive and the Company waive the right to resolve any such dispute through a trial by jury or judge or by administrative proceeding. The Executive will have the right to be represented by legal counsel at any
arbitration proceeding. The arbitrator shall: (1) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be available under applicable law in a court proceeding; and
(2) issue a written statement signed by the arbitrator regarding the disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential findings and conclusions on which
the award is based. The Company shall pay all filing fees in excess of those which would be required if the dispute were decided in a court of law, and shall pay the arbitrator’s fees and any other fees or costs unique to arbitration. Except as
may be awarded by the arbitrator, each party shall bear its own legal fees in connection with such arbitration. Nothing in this Agreement shall prevent either the Executive or the Company from obtaining injunctive relief in court to prevent
irreparable harm pending the conclusion of any such arbitration, including but not limited to any harm caused by violations of Paragraph 9, including, but not limited to Paragraph 9(c) [Non-Competition]. Any awards or orders in such arbitrations may
be entered and enforced as judgments in the federal and state courts of any competent jurisdiction.
