 Exhibit 10.1 

SEATTLE GENETICS, INC. 

Senior Executive Annual Bonus Plan 

This Senior Executive Annual Bonus Plan (the “Plan”) is intended to enhance stockholder value by promoting a connection between the
performance of Seattle Genetics, Inc. (the “Company”) and the compensation of senior executives of the Company and to promote retention of participating senior executives. 

1. Executives of the Company at the Vice President level and above (“Participants”) are eligible to receive annual bonuses for each
calendar year (each, a “Plan Year”) according to this Plan. The Plan will be administered by the Compensation Committee of the Board of Directors of the Company (the “Committee”). The Committee shall have all powers and
discretion necessary to administer the Plan including any adjustments, amendments and modifications to the Plan or its application to all or any participants and to control its operation and may delegate responsibilities to Company officers as it
deems appropriate. Participants are eligible to receive bonuses for each Plan Year based on their individual performance and the Company’s performance during such Plan Year. A Participant who does not demonstrate satisfactory individual
performance (50% or higher) during any Plan Year, however, will not be eligible for any portion of his or her bonus for such Plan Year, including the portion based on Company performance. 

2. For each Plan Year, Company performance shall be determined by the Committee based on the Company’s ability to meet or exceed Company
goals for such Plan Year, as set forth by the Board of Directors of the Company, which may include such factors as: sales or commercial goals; research, development and clinical activities, milestones and go/no go decisions; hiring, retention,
development of plans and other operational goals; strategic alliances and acquisitions; acquisitions and licensing or partnering transactions; international expansion goals, government affairs and public policy goals; manufacturing and supply goals;
quality goals; regulatory goals; expense and cost reduction goals; debt reduction; improvement in or attainment of working capital levels; financings; implementation or completion of projects or processes; and financial metrics, including stock
price performance, profitability, cash flow or net income. For clarification, the Committee may determine in its sole discretion that the Company did not satisfactorily complete enough goals for the applicable Plan Year and in that case, the
Committee may determine that no bonus shall be paid to Participants for such Plan Year. For each Plan Year, individual performance of the Participants who are senior executives on the Executive Committee and, if applicable, any other employee who is
an “officer” within the meaning of Rule 16a-1(f) under the Exchange Act (each, an “Executive Officer”), shall be determined by the Committee upon review and recommendation to the Committee by the Head of Human Resources and the
Chief Executive Officer, except for the individual performance of the Chief Executive Officer, which shall be determined by the Committee. For each Plan Year, individual performance of Participants who are not Executive Officers (“Other
Officers”) will be reviewed and determined by the CEO. In all cases, awards shall be based on the individual Participant’s satisfactory completion of individual performance goals established for the applicable Plan Year (if and to the
extent applicable) and/or the individual Participant’s contribution to the Company’s success in achieving the Company goals for such Plan Year. 

 3. To be eligible for a bonus for any Plan Year, a Participant must be on the Company’s
payroll prior to November 1 of such Plan Year and must be employed by the Company as of the date of payment of the bonus. A Participant hired after commencement of any Plan Year shall be eligible for a pro-rated bonus for such Plan Year. A
Participant who, during any Plan Year, is promoted into a position with a higher bonus target will have a pro-rated bonus based on his or her time in each position during such Plan Year and the applicable individual performance targets for such
positions for such Plan Year, but calculated based on the Participant’s annual base pay as of the last day of such Plan Year. 
 4. A
Participant who has taken an approved leave of absence pursuant to the Company’s policies of longer than 90 calendar days during any Plan Year shall receive a pro-rated bonus for such Plan Year, calculated by excluding the number of days that
exceed 90 calendar days during such Plan Year that he or she was on an approved leave of absence. For example, a person on an approved leave of absence for 100 days is eligible for a pro-rated bonus by subtracting 10 days from the bonus calculation.

 5. A Participant who is on an approved leave of absence on the date the bonus payment for any Plan Year is made will be eligible to
receive a bonus for such Plan Year on the bonus payment date, provided that such bonus will be pro-rated as calculated above if he or she was on an approved leave of absence for longer than 90 calendar days during such Plan Year. 

6. The amount of a Participant’s bonus for each Plan Year is based on a target percentage of such Participant’s annual base pay as
of the last day of such Plan Year. This target percentage shall be determined by the Committee in the case of Executive Officers or the CEO in the case of a Participant who is an Other Officer at the beginning of each Plan Year. The target
percentage for such Plan Year shall then be adjusted based on the Company’s performance and the individual Participant’s performance over the course of such Plan Year to arrive at a final performance percentage for such Plan Year. For all
Participants who are Other Officers, the final performance percentage for each Plan Year shall be based 50% on the Company’s performance and 50% on each Participant’s individual performance. For those Participants that are Executive
Officers, other than the Chief Executive Officer and the Chief Operating Officer, the final performance percentage for each Plan Year shall be based 60% on the Company’s performance and 40% on each Participant’s performance. The Chief
Operating Officer’s final performance percentage for each Plan Year shall be based 80% on the Company’s performance and 20% on the Participant’s performance and the Chief Executive Officer’s final performance percentage for each
Plan Year shall be determined by the Committee in its sole discretion. For any Plan Year, the Company performance percentage and/or the individual performance percentage may exceed 100% in the event the Company or the individual Participant exceeds
expected goals, provided that neither percentage may exceed 150%. For example, for an applicable Plan Year, assuming the Company has met 100% of its goals, a Participant who is an Other Officer, who has met 150% of his or her individuals goals, has
a target percentage of 25% and has a base pay rate of $100,000 will receive a bonus of $31,250 for such Plan Year (100% x 0.5 + 150% x 0.5 = 125%; and 125% x 25% = 31.25%; and 31.25% of Participant’s base pay rate of $100,000 = $31,250). A
Participant’s bonus for any Plan Year may be paid in cash or stock or a combination of both at the discretion of the Committee. All determinations and decisions made by the Committee or the CEO as applicable shall be final, conclusive and
binding on all persons and shall be given the maximum deference permitted by law. 

 7. This Plan is effective as of January 1, 2017. Bonus payments for each Plan Year will be
made by February 15th following the end of such Plan Year. 
 8. The Company shall
provide a copy of this Plan to each Participant and communicate to each Participant his or her target percentage for each Plan Year as determined by the Committee at the beginning of such Plan Year. 

9. This Plan supersedes all prior bonus plans or any written or verbal representations regarding the subject matter of this Plan and is the
entire understanding between the Company and the Participant regarding the subject matter of this Plan. Participation in this Plan for any Plan Year will not convey any entitlement to participate in this Plan for any future Plan Year or in any
future plans or to the same or similar future bonus payments. The Committee may at any time amend, suspend, or terminate this Plan, including amendment of the target percentages for each Participant and amendment so as to ensure that no amount paid
or to be paid hereunder shall be subject to the provisions of Section 409(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the “Code”). For the avoidance of doubt, it is intended that the Plan satisfy the exemption from the
application of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder and any state law of similar effect provided under Section 1.409A-1(b)(4) of the Treasury Regulations, and the Plan shall be
administered and interpreted to the greatest extent possible in compliance therewith. 
 10. The Company shall withhold all applicable taxes
from any bonus payment, including any federal, state and local taxes. 
 11. Nothing in this Plan shall interfere with or limit in any way
the right of the Company to terminate any Participant’s employment or service at any time, with or without cause. Nothing in these guidelines should be construed as an employment agreement or an entitlement to any Participant for any incentive
payment hereunder. 
 12. This Plan and all awards shall be construed in accordance with and governed by the laws of the State of
Washington, without regard to its conflict of law provisions. 
 13. Payments under this Plan shall be unsecured, unfunded obligations of
the Company. To the extent a Participant has any rights under this Plan, the Participant’s rights shall be those of a general unsecured creditor of the Company.EX-10.1

 WHEREAS, each Shareholder beneficially owns (as such term is used in

into the Merger Agreement and as an inducement and in consideration therefor, each Shareholder is entering into this Agreement. 
 NOW,
THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties
hereto agree as follows:

entry without the prior written consent of the Shareholders into any amendment or modification of the Merger Agreement, or any written waiver of the Company’s rights under the Merger Agreement made in connection with a request from Parent, in
each case, which results in a decrease in, or change in the composition of, the Merger Consideration payable to any Shareholder (such earliest date, the “Expiration Date”), each Shareholder irrevocably and unconditionally hereby
agrees that at any meeting (whether annual or special and each adjourned or postponed meeting) of the Company’s shareholders, however called, or in connection with any written consent of the Company’s shareholders, the Shareholder will
(i) appear at such meeting or otherwise cause all of its Existing Shares and other shares of Common Stock over which it has acquired beneficial ownership after the date hereof 

 
(including any shares of Common Stock acquired by means of purchase, dividend or distribution, or issued upon the exercise of any stock options, warrants or other rights to acquire Common Stock
or the conversion of any convertible securities or otherwise) (collectively, the “New Shares”, and together with the Existing Shares, the “Shares”), which it beneficially owns as of the applicable record date, to be
counted as present at the meeting for purposes of calculating a quorum and (ii) vote or cause to be voted (including by proxy or written consent, if applicable) all such Shares (A) in favor of the approval of the Merger Agreement and the
principal terms of the Merger, (B) in favor of any proposal to adjourn or postpone such meeting of the Company’s shareholders to a later date if such adjournment or postponement is (1) with the written consent of Parent, (2) for
the absence of a quorum, (3) to allow additional solicitation of votes in order to obtain the Company Shareholder Approval, or (4) as required by Law (in each such case only for a period of not more than thirty (30) calendar days,
individually or in the aggregate, and not past two (2) Business Days prior to the End Date), (C) against any action, proposal, transaction or agreement in favor of an Acquisition Proposal, including a Superior Proposal, without regard to the

any sale, lease or transfer of all or substantially all of the assets of the Company or any of its Subsidiaries, (F) against any reorganization, recapitalization, extraordinary dividend, dissolution, liquidation or winding up of the Company or
any of its Subsidiaries, (G) against any material change in the capitalization of the Company or any of its Subsidiaries, or the corporate structure of the Company or any of its Subsidiaries, (H) to the extent submitted to a shareholder
vote, against any change in the business management or Board of Directors of the Company (other than as directed by Parent) and (I) against any action, proposal, transaction or agreement that is intended to or would (1) result in an
inaccuracy of any representation or warranty, or a breach of any covenant, or any other obligation or agreement, of the Company contained in the Merger Agreement, or of a Shareholder contained in this Agreement, or (2) prevent, materially
impede, materially delay or otherwise materially and adversely affect the Company’s, Parent’s or Merger Sub’s ability to timely consummate the transactions contemplated by the Merger Agreement, including the Merger (clauses
(A) through (I), the “Required Votes”). Except as explicitly set forth in this Section 1.1, nothing in this Agreement shall limit the right of each Shareholder to vote (including by proxy or written
consent, if applicable) in favor of, against or abstain with respect to any other matters presented to the Company’s shareholders. 

Section 1.2       Grant of Irrevocable Proxy; Appointment of Proxy. 

(a) From and after the date hereof until the Expiration Date, each Shareholder hereby irrevocably and unconditionally grants to, and
appoints, Parent and any designee thereof as such Shareholder’s proxy and attorney-in-fact (with full power of substitution) in accordance with Section 705(e) of
the California General Corporation Law, for and in the name, place and stead of such Shareholder, to vote or cause to be voted (including by proxy or written consent, if applicable) the Shares owned by such Shareholder as of the applicable record
date in accordance with the Required Votes; provided that each Shareholder’s grant of the proxy contemplated by this Section 1.2 shall be effective if, and only if, such Shareholder has not delivered to the
Company prior to the meeting at which any of the matters described in Section 1.1 are to be considered, a duly executed irrevocable proxy card directing that the Shares of such Shareholder be voted in accordance with the Required
Votes; provided, 

  
 -2- 

 
further, that any grant of such proxy shall only entitle Parent or its designee to vote on the matters specified by Section 1.1(ii), and each Shareholder shall retain the authority
to vote on all other matters.  
 (b) Each Shareholder hereby represents that any proxies heretofore given in respect of the Shares,
if any, are revocable, and hereby revokes all such proxies. 
 (c) Each Shareholder hereby affirms that the irrevocable proxy set forth in
this Section 1.2, if it becomes effective, is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Shareholder under this
Agreement. The parties hereby further affirm that the irrevocable proxy, if it becomes effective, is coupled with an interest and is intended to be irrevocable until the Expiration Date, at which time it will terminate automatically, and any
underlying appointment shall automatically be revoked and rescinded and of no force and effect, in each case without further action by any party. The proxy granted by the Shareholders herein shall survive the dissolution, bankruptcy, death or
incapacity of any Shareholder. If for any reason any proxy granted herein is not irrevocable after it becomes effective, then the Shareholder granting such proxy agrees, until the Expiration Date, to vote, or to cause the holder of record on any
applicable record date to vote, the Shares in accordance with the Required Votes. The parties agree that the foregoing is a voting agreement. 

Section 1.3        Restrictions on Transfers. 

(a) Absent the prior written consent of Parent (which consent may be granted or withheld in Parent’s sole discretion), each Shareholder
hereby agrees that, from the date hereof until the Expiration Date, it shall not, directly or indirectly, (i) sell, transfer, assign, tender in any tender or exchange offer, pledge, encumber, hypothecate or similarly dispose of (by merger, by
testamentary disposition, by operation of applicable Law or otherwise) (a “Transfer”), either voluntarily or involuntarily, or enter into any contract, option or other arrangement or understanding providing for the Transfer of any Shares
(or any Rights attached thereto, or any economic interests therein), (ii) deposit any Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto, or (iii) agree
(whether or not in writing) to take any of the actions prohibited by the foregoing clause (i) or (ii). Any purported Transfer of Shares inconsistent with this Section 1.3 shall be null and void. 

(b) The restrictions set forth in Section 1.3(a) shall not apply to: (i) in the case of any Shareholder that is a natural person,
any Transfer of Shares by will or the laws of intestacy, or (ii) the Transfer of some or all Shares to any trust, partnership, corporation or limited liability company established and held for the direct or indirect benefit of the Shareholder
or his family members; provided that, in each case, the transferee shall concurrently with such Transfer execute a customary joinder in form and substance reasonably satisfactory to Parent agreeing to be a “Shareholder” hereunder if such
transferee is not already a party to this Agreement, and to perform all obligations as a Shareholder pursuant to this Agreement with respect to the Shares. 

  
 -3- 

 Section 1.4       Inconsistent Agreements. 
Each Shareholder hereby covenants and agrees that, except for this Agreement, it (a) shall not enter into at any time while this Agreement remains in effect, any voting agreement or voting trust with respect to the Shares and (b) shall not
grant at any time while this Agreement remains in effect a proxy, consent or power of attorney with respect to the Shares. 
 ARTICLE II 

NO SOLICITATION

applicable) each of its Affiliates and its and their respective directors, officers or employees not to, and shall use its reasonable best efforts to cause its and their other Representatives not to, directly or indirectly, (i) solicit,
initiate, knowingly encourage, or knowingly facilitate any Acquisition Proposal or any inquiry, expression of interest, proposal, offer or request for information that would reasonably be expected to lead to or result in an Acquisition Proposal, or
the making or consummation thereof, (ii) other than to inform any Person of the existence of the provisions contained in this Section 2.1, enter into, continue or otherwise participate in any discussions or negotiations regarding, or
furnish to any Person any information in connection with, or enter into any Contract or other agreement or understanding with respect to, any Acquisition Proposal or any inquiry, expression of interest, proposal, offer or request for information
that would reasonably be expected to lead to or result in an Acquisition Proposal, or (iii) resolve or agree to do any of the foregoing; provided that nothing herein shall prohibit any Shareholder or any of its Affiliates or
Representatives from participating in any discussions or negotiations with respect to such Shareholder’s willingness to enter into a voting agreement in connection with an Acquisition Proposal to the extent that the Company becomes permitted to
take the actions set forth in clause (i) and clause (ii) of Section 5.02(b) of the Merger Agreement with respect to such Acquisition Proposal. Other than subject to the proviso in the foregoing sentence, from and after the execution of
this Agreement, each Shareholder shall, and shall cause (if applicable) each of its Affiliates and direct its and their respective Representatives to immediately cease and cause to be terminated all existing discussions or negotiations with any
Person conducted heretofore with respect to any Acquisition Proposal or any inquiry, expression of interest, proposal, offer or request for information that would reasonably be expected to lead to or result in an Acquisition Proposal. 

(b) Prior to the Expiration Date, each Shareholder shall promptly (and in any event within 24 hours following the date of receipt) advise
Parent and the Company in writing in the event that it or any of its Affiliates, any of its or its Affiliates’ officers, directors or employees or, to the Shareholders’ knowledge, any of its or its Affiliates’ other Representatives
receives any Acquisition Proposal, and in connection with such notice, provide to Parent and the Company the material terms and conditions (including the identity of the third party making any such Acquisition Proposal, indication or request, and
copies of any related documentation, including any related financing commitments) of any such Acquisition Proposal. 
 (c) For purposes of
this Agreement, the term “Affiliate” shall have the meaning assigned to it in the Merger Agreement; provided, that, for the avoidance of doubt, the Company shall not be deemed to be an Affiliate of any of the Shareholders.

amended or waived if, and only if, such amendment or waiver is in writing and signed (a) in the case of an amendment, by Parent, the Company and each Shareholder, and (b) in the case of a waiver, by the party (or parties) against whom the
waiver is to be effective. No failure or delay by any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. 

Section 5.5       Assignment.  Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned or delegated (including by sale of stock, operation of applicable Law in connection with a merger or sale of substantially all the assets) by any of the parties hereto without the prior written
consent of the other parties, except that Parent may assign, in its sole discretion, all or any of the rights, interests or obligations hereunder to any of its Affiliates. Any purported assignment inconsistent with this
Section 5.5 shall be null and void. 
 Section 5.6       No

 Section 5.7       Entire
Agreement.  This Agreement (including Schedule A hereto) and, to the extent referenced herein, the Merger Agreement, constitute the entire agreement, and supersede all other prior and contemporaneous agreements, understandings,
undertakings, arrangements, representations and warranties, both written and oral, among the parties with respect to the subject matter hereof. 

Section 5.8       No Third-Party Beneficiaries.  Each Shareholder and Parent agrees
that (a) its representations, warranties, covenants and agreements set forth herein are solely for the benefit of Parent (in the case of a Shareholder) or each Shareholder (in the case of Parent), in accordance with and subject to the terms of
this Agreement, and (b) this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth
herein. 
 Section 5.9       Jurisdiction; Specific Enforcement; Waiver of Trial by Jury.

 (a)      Each party hereby submits to the exclusive jurisdiction of the federal court in the Central
District of California and any appellate courts therefrom, or if that court does not have subject matter jurisdiction, in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (the “Chosen
Courts”), for any dispute arising out of or relating to this Agreement or the breach, termination or validity thereof. Each Party hereby irrevocably and unconditionally waives, to the fullest extent permitted by Law, any objection that it
may now or hereafter have to the laying of the venue of any such proceedings brought in such court. Each of the parties irrevocably and unconditionally waives and agrees not to plead or argue in any such court (i) that it is not personally
subject to the jurisdiction of the Chosen Courts for any reason other than the failure to serve process in accordance with applicable Law, (ii) that it or its property is exempt or immune from jurisdiction of the Chosen Courts or from any legal
process commenced in the Chosen Courts (including but not limited to service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (iii) to the fullest extent permitted by
applicable Law that (X) the suit, action, or proceeding in the Chosen Courts is brought in an inconvenient forum, (Y) the venue of such suit, action, or proceeding is improper, and (Z) this Agreement, or the subject matter hereof, may
not be enforced in or by the Chosen Courts. Each party agrees that notice or the service of process in any Action arising out of or relating to this Agreement or the transactions contemplated hereby shall be properly served or delivered if delivered
in the manner contemplated by Section 5.3 or in any other manner permitted by applicable Law. 

(b)      EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

Section 5.10      Specific Performance; Remedies.  Each of the Shareholders agrees and
acknowledges that irreparable harm would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Each of the Shareholders accordingly agrees that, without
posting bond or other undertaking, Parent shall be entitled to seek injunctive or other equitable relief to prevent 

  
 -10- 

 
breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of competent jurisdiction, this being in addition to any other remedy to which they
are entitled at law or in equity. In the event that any such action is brought in equity to enforce the provisions of this Agreement, no Shareholder will allege, and each Shareholder hereby waives the defense or counterclaim, that there is an
adequate remedy at law. 
 Section 5.11       Governing Law.  This Agreement and
any Actions arising out of or related to this Agreement or to the inducement of any party hereto to enter into this Agreement (whether for breach of contract, tortious conduct or otherwise and whether predicated on common law, statute or otherwise)
shall be governed by and construed in accordance with the applicable Law of the State of Delaware, including all matters of construction, validity and performance, without regard to the conflicts of law rules of such State that would refer a matter
to the laws of another jurisdiction; provided that matters relating to the Merger and the exercise of the dissenters’ rights shall be governed by the applicable Law of the State of California. 

Section 5.12       Non-Survival of Representations and
Warranties. The representations and warranties of the Shareholders contained herein shall not survive the closing of the transactions contemplated hereby and by the Merger Agreement. 

Section 5.13       Headings.  Headings of the Articles and Sections of this Agreement
are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever. 

Section 5.14       Interpretation.  When a reference is made in this Agreement to an
Article, Section or Schedule, such reference shall be to an Article, Section or Schedule of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this
Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this
Agreement as a whole and not to any particular provision of this Agreement, unless the context otherwise requires. The word “extent” and the phrase “to the extent” when used in this Agreement shall mean the degree to which a
subject or other thing extends, and such word or phrase shall not mean simply “if”. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the
feminine and neuter genders of such term. References in this Agreement to specific laws or to specific provisions of laws shall include all rules and regulations promulgated thereunder, and any statute defined or referred to herein or in any
agreement or instrument referred to herein shall mean such statute as from time to time amended, modified or supplemented, including by succession of comparable successor statutes. Each of the parties has participated in the drafting and negotiation
of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue
of authorship of any of the provisions of this Agreement. 

Section 5.15       Counterparts.  This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof
signed by all of the other parties hereto. 

  
 -11- 

 
Until and unless each party hereto has received a counterpart hereof signed by each other party hereto, this Agreement shall have no effect and no party shall have any right or obligation
hereunder (whether by virtue of any other oral or written agreement or other communication). Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in PDF form, or by any other electronic means designed to preserve
the original graphic and pictorial appearance of a document, will be deemed to have the same effect as physical delivery of the paper document bearing the original signatures. 

Section 5.16       Severability.  Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any
other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is unenforceable and a suitable and equitable provision shall be substituted therefor in order to
carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision. 

Section 5.17       No Agreement as Director or Officer.  Notwithstanding any
provision of this Agreement to the contrary, each Shareholder has entered into this Agreement in its capacity as a shareholder of the Company, and nothing in this Agreement shall limit, restrict or otherwise affect the ability of any Shareholder who
is a director or officer of the Company to act, refrain from acting or vote on any matter, in each case, in his or her capacity as a director or officer of Company, or be construed to prohibit, limit or restrict such Shareholder who is a director or
officer of the Company from exercising his or her fiduciary duties as a director or officer to the Company or its shareholders under applicable Law, including by causing the Company to exercise its rights under the Merger Agreement. 

Section 5.18       Liability. The rights and obligations of each of the Shareholders under this
Agreement shall be several and not joint. All references to actions to be taken by the Shareholders, or representations and warranties to be made, under this Agreement refer to actions to be taken or representations and warranties to be made by
Shareholders acting severally and not jointly. Except for any liability for claims, losses, damages, liabilities or other obligations arising out of a Shareholder’s breach of or inaccuracy in its representations and warranties hereunder or
failure to perform its obligations hereunder, Parent agrees that no Shareholder (in its capacity as a shareholder of Company) will be liable for claims, losses, damages, liabilities or other obligations resulting from or relating to the Merger
Agreement, including any breach by Company of the Merger Agreement, and that Company shall not be liable for claims, losses, damages, liabilities or other obligations resulting from or related to any Shareholder’s breach of or inaccuracy in its
representations and warranties hereunder or failure to perform its obligations hereunder. Except for (i) any liability for claims, losses, damages, liabilities or other obligations arising out of Parent’s breach of or inaccuracy in its
representations and warranties hereunder or failure to perform its obligations hereunder and (ii) such Shareholder’s right to enforce the provisions of Section 5.06 (in his or her capacity as an Indemnified Party as defined in the
Merger Agreement) and Article 2 of the Merger Agreement in accordance with Section 8.06 of the Merger Agreement, each Shareholder agrees that Parent will not be liable to such Shareholder for claims, losses, damages, liabilities or other
obligations resulting from or relating to the Merger Agreement.

 Section 5.19       No Ownership
Interest. Nothing contained in this Agreement shall be deemed to vest in any other person any direct or indirect ownership or incident of ownership of or with respect to any Existing Shares. All rights, ownership and economic benefits of
and relating to the Existing Shares shall remain vested in and belong to the holder thereof, and no other person shall have any authority to exercise any power or authority to direct any Shareholder in the voting of any of the Existing Shares except
as provided in this Agreement.
