Voting Methods
If you are the “record holder” of your shares, meaning that you own your shares in your own name and not through a bank, broker or other nominee, you may vote in one of four ways:
(1) You may vote over the Internet. You may vote your shares by following the “Vote by Internet” instructions in the Notice or on the enclosed proxy card. If you vote over the Internet, you do not need to vote by telephone, by completing and mailing your proxy card or by voting in person at the 20172019 Annual Meeting.
(2) You may vote by telephone. You may vote your shares by following the “Vote by Phone” instructions in the Notice or on the enclosed proxy card. If you vote by telephone, you do not need to vote over the Internet, by completing and mailing your proxy card or by voting in person at the 20172019 Annual Meeting.
(3) You may vote by mail. If you received (or requested to receive) a printed copy of the proxy materials, you may vote by completing, dating and signing the proxy card and promptly mailing it in the postage-paid envelope provided. If you vote by mail, you do not need to vote over the Internet, by telephone or by voting in person at the 20172019 Annual Meeting.
(4) You may vote in person. If you attend the 20172019 Annual Meeting, you may vote by delivering your completed proxy card in person or you may vote by completing a ballot at the 20172019 Annual Meeting. Ballots will be available at the 20172019 Annual Meeting. Any vote cast at the 20172019 Annual Meeting will serve to revoke any prior vote made by Internet, telephone or mail.
All proxies that are executed or are otherwise submitted over the Internet or by telephone will be voted on the matters set forth in the accompanying Notice in accordance with the stockholders’ instructions. However, if no choice is specified on a proxy as to one or more of the proposals, the proxy will be voted in accordance with the Board's recommendations on such proposals as set forth in this proxy statement.

Shares Held in Street Name
If the shares you own are held in “street name” by a bank, broker or other nominee record holder, which, for convenience, we collectively refer to in this proxy statement as a brokerage firms,firm, your brokerage firm, as the record holder of your shares, is required to vote your shares according to your instructions. In order to vote your shares, change your vote or revoke your instructions, you will need to follow the directions your brokerage firm provides you. Many brokerage firms also offer the option of providing for voting over the Internet or by telephone, instructions for which, if available, would be provided by your brokerage firm on the voting instruction form that it delivers to you. Because most brokerage firms are member organizations of the New York Stock Exchange, or NYSE, the rules of the NYSE will likely govern how your brokerage firm would be permitted to vote your shares in the absence of instruction from you. Under the current rules of the NYSE, if you do not give instructions to your brokerage firm, it will still be able to vote your shares with respect to certain “discretionary” items, but will not be allowed to vote your shares with respect to certain “non-discretionary” items. The ratification of Ernst & Young LLP as our independent registered public accounting firm (Proposal 2)3) is considered to be a discretionary item under the NYSE rules, and your brokerage firm will be able to vote on thatthis item even if it does not receive instructions from you, so long as it holds your shares in its name. The election of class IIIII directors (Proposal 1) is aand the approval of an amendment to our 2014 Plan (Proposal 2) are each “non-discretionary” item,items, meaning that if you do not instruct your brokerage firm on how to vote with respect to Proposal 1 or Proposal 2, your brokerage firm will not vote with respect to that proposalthose proposals and your shares will be counted as “broker non-votes.” “Broker non-votes” are shares that are held in “street name” by a brokerage firm that indicates on its proxy that it does not have or did not exercise discretionary authority to vote on a particular matter.
If your shares are held in street name, you must bring an account statement from your brokerage firm showing that you are the beneficial owner of the shares as of the Record Date in order to be admitted to the 20172019 Annual Meeting. To be able to vote your shares held in street name at the 20172019 Annual Meeting, you will need to obtain a proxy card from the holder of record.

In addition, Rule 10C-1 under the Exchange Act requires that, with respect to the independence of each member of our compensation committee, our Board consider all factors specifically relevant to determining whether a director has a relationship with us which is material to that director’s ability to be independent from management in connection with his or her duties as a compensation committee member, including, but not limited to: (1) the source of his or her compensation as a director, including any consulting, advisory or other compensatory fee paid by us to him or her; and (2) whether he or she is affiliated with us or any of our subsidiaries or affiliates.

In making such determination, our Board considered the relationships that each such non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining independence.
No director is related to any of our other directors or executive officers and there are no arrangements or understandings between a director and any other person pursuant to which such person was elected as director, except for Mr. Dan who was originally appointed to our Board as a condition to the closing of our acquisition of Viventia in 2016.

Each committee reports to the full boardBoard on a regular basis, including reports with respect to the committee’s risk oversight activities as appropriate.

Executive Sessions
Executive sessions of our independent directors are held at each regularly scheduled meeting of our Board and at other times they deem necessary. Our Board’s policy is to hold executive sessions both with and without the presence of management. Our Board committees also generally meet in executive session at the end of each committee meeting.

The process followed by our nominating and corporate governance committee and the independent directors of our Board to identify and evaluate director candidates may include requests to boardBoard members and others for recommendations, evaluation of the performance on our Board and its committees of any existing directors being considered for nomination, consideration of biographical information and background material relating to potential candidates and, particularly in the case of potential


candidates who are not then serving on our board,Board, interviews of selected candidates by members of our nominating and corporate governance committee and the independent directors of our Board.
In considering whether to recommend any particular candidate for inclusion in our Board’s slate of recommended director nominees, our nominating and corporate governance committee and the independent directors of our Board apply the criteria set forth in our corporate governance guidelines described below under “Corporate Governance Guidelines”. Consistent with these criteria, our nominating and corporate governance committee and the independent directors of our Board expect every nominee to have the following attributes or characteristics, among others: integrity, honesty, adherence to high ethical standards, business acumen, good judgment and a commitment to understand our business and industry.
Each of the director nominees is currently a member of our Board. The nominee biographies under “Board of Directors—Members of Our Board of Directors” indicate the experience, qualifications, attributes and skills of each of our current directors that led our nominating and corporate governance committee and the independent directors of our Board to conclude he or she should continue to serve as a member of our Board. Our nominating and corporate governance committee and the independent directors of our Board believe that each of the nominees has the individual attributes and characteristics required of each of our directors, and that the nominees as a group possess the skill sets and specific experience desired of our Board as a whole.
Our nominating and corporate governance committee and the independent directors of our Board consider the value of diversity when selecting nominees, and believe that our board,Board, taken as a whole, should embody a diverse set of skills, experiences and abilities. Our nominating and corporate governance committee and the independent directors of our Board do not make any particular weighting of diversity or any other characteristic in evaluating nominees and directors.
Stockholders may recommend individuals for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials, and information with respect to the stockholder or group of stockholders making the recommendation, including the number of shares of common stock owned by such stockholder or group of stockholders, to our Corporate Secretary at Eleven Biotherapeutics,Sesen Bio, Inc., 245 First Street, Suite 1800, Cambridge, MA 02142, Attention: Corporate Secretary.

Executive and Director Compensation Processes
Our executive compensation program is administered by the compensation committee of our Board, subject to the oversight and approval of our full Board. Our compensation committee reviews our executive compensation practices on an annual basis


and based on this review makes recommendations to our Board for approval, which has full discretion to approve or modify the recommendations of the compensation committee.
In designing our executive compensation program, our compensation committee considers publicly available compensation data for national and regional companies in the biotechnology/pharmaceutical industry to help guide its executive compensation decisions at the time of hiring and for subsequent adjustments in compensation. Our compensation committee has also retained the services of Radford, an independent compensation consultant, to provide it with additional comparative data on executive compensation practices in our industry and to advise it on our executive compensation program generally. Although the compensation committee considers Radford’s advice and recommendations about our executive compensation program, the compensation committee ultimately makes its own decisions about these matters.
None of the compensation committee members and none of our executive officers or directors have any relationship with Radford or the individual consultants employed by Radford. Radford has not provided any other services to our Board or management other than compensation consulting services to the compensation committee. The compensation committee has determined that no conflicts of interest exist between Radford and our company, our directors or our executive officers. The compensation committee is directly responsible for the appointment and oversight of any compensation consultants and other advisors it retains.
Our director compensation program is administered by the compensation committee of our Board, subject to the oversight and approval of our full Board. The compensation committee conducts periodic reviews of director compensation and makes recommendations to the boardBoard with respect thereto.
Corporate Governance Guidelines
Our Board has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of our stockholders. The guidelines provide that:
 
our Board’s principal responsibility is to oversee our management;
a majority of the members of our boardBoard must be independent directors;
the independent directors meet in executive session at least twice a year;
directors have full and free access to management and, as necessary, independent advisors;
new directors participate in an orientation program and all directors are expected to participate in continuing director education on an ongoing basis; and
our boardBoard will conduct an annual self-evaluation to determine whether it and its committees are functioning effectively.
A copy of the corporate governance guidelines is posted under the heading “Corporate Governance” on the Investor Relations section of our website, which is located at ir.elevenbio.com.www.sesenbio.com.


Board Policies
Related Person Transactions
Our Board has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which our company is a participant, the amount involved exceeds $120,000 and one of our executive officers, directors, director nominees or 5% stockholders, or their immediate family members, each of whom we refer to as a “related person,” has a direct or indirect material interest. As a smaller reporting company, we are also required to review and approve any transaction, arrangement or relationship in which our company is a participant, the amount involved exceeds the lesser of $120,000 and or one percent of the average of our total assets at year-end for the last two completed fiscal years, and a related person has a direct or indirect material interest. Because one percent of our average total assets for the past two fiscal years has exceeded $120,000, our boardBoard has continued to apply the $120,000 threshold under our policy.
If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related person transaction,” the related person must report the proposed related person transaction to our principal accounting officer. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by our audit committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the committee will review, and, in its discretion, may ratify the related person transaction.transaction or direct that such transaction be terminated and rescinded. The policy also permits the chair of the audit committee to review and, if deemed appropriate, approve proposed


related person transactions that arise between committee meetings, subject to ratification by the audit committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.
A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the audit committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the audit committee will review and consider:
 
the related person’s interest in the related person transaction;
the approximate dollar value of the amount involved in the related person transaction;
the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
whether the transaction was undertaken in the ordinary course of our business;
whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
the purpose of, and the potential benefits to us of, the transaction; and
any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
Our audit committee may approve or ratify the transaction only if it determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. Our audit committee may impose any conditions on the related person transaction that it deems appropriate.
In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, our Board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:
 
interests arising solely from the related person’s position as an executive officer of another entity, whether or not the person is also a director of the entity, that is a participant in the transaction where the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction and the amount involved in the transaction is less than the greater of $200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction;$120,000; and
a transaction that is specifically contemplated by provisions of our certificate of incorporation or by-laws.
The policy provides that transactions involving the compensation of executive officers shall be reviewed and approved by our compensation committee in the manner specified in the compensation committee’s charter.
Certain Relationships and Related Party Transactions


Since January 1, 2016,2017, we have engaged in the following transactions with our directors, executive officers, holders of more than 5% of our voting securities, and affiliates or immediate family members of our directors, executive officers, and holders of more than 5% of our voting securities. We believe that all of these transactions were on terms as favorable as could have been obtained from unrelated third parties.

Employment Agreements with Current Executive Officers
In August 2015, we entered into an employment agreement with Mr. McCabe in connection with his promotion to Senior Vice President of Finance. In addition, in September 2016, we entered into employment agreements with Mr. Hurly and Dr. DeCillis. Each of these agreements provides that employment will continue until either we or the executive officer provides notice of termination in accordance with the terms of the agreement. In addition, we have entered into non-competition, non-solicitation, confidentiality and assignment agreements with each of our executive officers which prohibit them from competing with us, soliciting our employees and customers and disclosing confidential information during the term of their employment and for a specified time thereafter.
Pursuant to their respective employment agreements, each of our executive officers is entitled to receive an annual base salary as follows: Mr. Hurly, $425,000; Mr. McCabe, $265,000; and Dr. DeCillis, $417,000. In February 2016, our Board approved a


merit based salary increase retroactively effective to January 1, 2016 for Mr. McCabe, whose annual base salary was increased to $305,000.
In addition, pursuant to their respective employment agreements, each of our executive officers is eligible to receive an annual cash bonus, which is based on the achievement of individual and corporate performance objectives, calculated as a percentage of the executive’s annual base salary, and which will be determined by our Board, in its sole discretion, as follows: Mr. Hurly 50%, Mr. McCabe 25%, and Dr. DeCillis 30%. In connection with Mr. McCabe’s promotion to Chief Financial Officer, the Board approved an increase to the target bonus for Mr. McCabe from 25% of his annual base salary in 2015 to 30% of his annual base salary in 2016.
In connection with the Acquisition, we also entered into a retention letter agreement with Mr. McCabe, who continued to serve as our Chief Financial Officer following the closing of the Acquisition. The retention letter agreement, as subsequently amended on March 5, 2017, provides that Mr. McCabe: (i) would receive a $75,000 bonus at the closing of the Acquisition, (ii) is eligible for an additional $75,000 retention bonus payable in twelve months or earlier if his employment is terminated without cause or for good reason (each as defined in his employment agreement); (iii) may voluntarily resign without good reason (as defined in his employment agreement) within the twelve-month period following the closing of the Acquisition and receive the post-change in control severance benefits under his employment agreement, provided however, in such case, Mr. McCabe would forego the above described retention bonus, and (iv) would receive options to purchase 100,000 shares of our common stock at an exercise price of $3.37 per share.

401(k) Plan
We maintain a defined contribution employee401(k) retirement plan for our employees. Our 401(k) plan is intendedemployees in which substantially all of our full-time U.S. employees are eligible to qualify as a tax-qualified plan under Section 401 of the Code so that contributions toparticipate, including our 401(k) plan, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the 401(k) plan. Our 401(k) plan provides that each participant may contribute up to 75% of his or her pre-tax compensation, up to a statutory limit, which was $18,000 for 2016. Participants who are at least 50 years old can also make “catch-up” contributions, which in 2016 was up to an additional $6,000 above the statutory limit. Under our 401(k) plan, each employee is fully vested in his or her deferred salary contributions. Employee contributions are held and invested by the plan’s trustee, subject to participants’ ability to give investment directions by following certain procedures. We can make discretionary contributions or matching contributions to our 401(k) plan based on a percentage of contributions made by the employee. We may limit the amount of discretionary contributions up to a specified percentage or dollar amount. Viventia sponsors a 401(k) retirement plan for its U.S.-based employees.named executive officers. Participants may contribute a percentage of their annual compensation to this plan, subject to statutory limitations. We made matching contributions of $18,281 to the plan for the year ended December 31, 2018.
Limitation of Liability and Indemnification
Our certificate of incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law, or the DGCL, and provides that no director will have personal liability to


us or to our stockholders for monetary damages for breach of fiduciary duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:
 
for any breach of the director’s duty of loyalty to us or our stockholders;
for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
for voting for or assenting to unlawful payments of dividends, stock repurchases or other distributions; or
for any transaction from which the director derived an improper personal benefit.
Any amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to such amendment or repeal. If the DGCL is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the DGCL.
In addition, our certificate of incorporation provides that we must indemnify our directors and officers and we must advance expenses, including attorneys’ fees, to our directors and officers in connection with legal proceedings, subject to very limited exceptions.
We maintain a general liability insurance policy that covers specified liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers. In addition, we have entered into indemnification agreements with all of our directors and executive officers. These indemnification agreements may require us, among other things, to indemnify each such director and executive officer for some expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by him in any action or proceeding arising out of his or her service as one of our directors or executive officers.
Some of our non-employee directors may, through their relationships with their employers, be insured or indemnified against specified liabilities incurred in their capacities as members of our Board.
Insofar as indemnification for liabilities arising under the Securities Act of 1933, or the Securities Act, may be permitted to directors, executive officers or persons controlling us, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Proposal 1: Election of Class III Directorsclass II directors
In accordance with the terms of our certificateRestated Certificate of incorporationIncorporation and our by-laws,Amended and Restated By-laws, our Board is divided into three classes, with each class serving staggered three-year terms. Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires. The members of the classes are divided as follows:
 
Class I: Leslie L. Dan Barry Gertz and Stephen Hurly,Thomas R. Cannell, and their term expires at the annual meeting of stockholders to be held in 2018.2021.
Class II: Paul Chaney, Wendy Dixon and Jay S. Duker, and their term expires at the 2019 Annual Meeting.
Class III: Jane V. Henderson and Daniel S. Lynch, and their term expires at the annual meeting of stockholders to be held in 2019.2020.
Class III: Abbie Celniker, Jane Henderson and Daniel Lynch, and their term expires at the2017 Annual Meeting.
At each annual meeting of stockholders, directors are elected for a full term of three years to succeed those directors whose terms are expiring. Dr. Celniker, Ms. HendersonDixon and Mr. LynchDr. Duker are current directors whose terms expire at the 20172019 Annual Meeting. Dr. Celniker, Ms. HendersonDixon and Mr. LynchDr. Duker are each nominated for re-election as a class IIIII director, with a term expiring at the annual meeting of stockholders to be held in 20202022, or our 2022 Annual Meeting, and upon the election and qualification of their respective successors.

Proposal 2: To Ratifyapprove an amendment of our 2014 Stock Incentive Plan, or the Selection2014 Plan, to (i) increase the number of shares reserved for issuance under our 2014 Plan by 7,908,972 shares and (ii) eliminate the “evergreen” or automatic replenishment provision of the 2014 Plan pursuant to which the number of shares authorized for issuance under the 2014 Plan is automatically increased on an annual basis.
The Board is asking the stockholders to approve an amendment of our 2014 Stock Incentive Plan, or the 2014 Plan, to (i) increase by 7,908,972 shares the number of shares of our common stock reserved for issuance under the 2014 Plan and (ii) eliminate the “evergreen” or automatic replenishment provision of the 2014 Plan pursuant to which the number of shares authorized for issuance under the 2014 Plan is automatically increased on an annual basis, or the 2014 Plan Amendment.
Upon the recommendation of the Compensation Committee, the Board approved the 2014 Plan Amendment, subject to the receipt of stockholder approval at the 2019 Annual Meeting. The Board believes that approval of the 2014 Plan Amendment is in the best interests of our stockholders and us because equity-based awards help to attract, motivate, and retain talented executives, employees, directors and other service providers, align employee and stockholder interests, link employee compensation with performance and maintain a culture based on employee share ownership. The Board recommends that the stockholders approve the 2014 Plan Amendment.
Our Board believes that the number of shares of common stock currently available for issuance under the 2014 Plan is insufficient to meet our future equity needs for incentive compensation. Before giving effect to the proposed amendment, an aggregate of approximately 1,319,184 shares are available for future grants under the 2014 Plan. The approval of an additional 7,908,972 shares will bring the total shares of our common stock available for future incentive compensation needs to approximately 9,228,156 shares. If stockholders do not approve the proposed amendment at the 2019 Annual Meeting, the 2014 Plan Amendment will not be effective, and the 2014 Plan will remain in effect without giving effect to the proposed amendment.
Our Board believes that the proposed amendment is vital to our ability to attract, retain and motivate top quality employees, directors and consultants as we execute our business strategy. Further, our Board believes that our interests and the interests of our stockholders will be advanced if we can continue to offer our employees, directors and consultants the opportunity to acquire or increase their proprietary interests in us by receiving awards under the 2014 Plan.
In its determination to approve the 2014 Plan Amendment, the Board reviewed an analysis prepared by Radford, the Compensation Committee’s compensation consultant, which included an analysis of our historical and likely prospective share usage, certain burn rate metrics and the costs associated with the 2014 Plan. Specifically, the Board considered that:
The Board believes that equity compensation has been, and will continue to be, a critical component of our compensation package because it (i) develops a culture of ownership among our employees and the Board, (ii) aligns the interests of our employees and the Board with the interests of our other stockholders and (iii) preserves our cash resources. To date, we have successfully competed for top talent, often in direct competition with much larger pharmaceutical companies with greater resources, in part because of our use of equity-based compensation. Equity awards are an essential part of our compensation package, are central to our employment value proposition, and are necessary for us to continue competing for top talent as we grow.

We expect the share authorization under the 2014 Plan, including the proposed increase described above, to provide us with enough shares for awards through the 2021 compensation cycle, assuming we continue to grant awards consistent with our current practices and historical usage, as reflected in our historical stock burn rate, and further dependent on the price of our common stock and hiring activity during the next few years, forfeitures of outstanding awards under the 2014 Plan, and noting that future circumstances may require us to change our current equity grant practices. We cannot predict our future equity grant practices, the future price of our common stock or future hiring activity with any degree of certainty at this time, and the share reserve under the 2014 Plan could last for a shorter or longer time.

Radford’s analysis, which is based on generally accepted evaluation methodologies used by investors and proxy advisory firms concluded that the increase of the number of shares under the 2014 Plan is well within generally accepted standards as measured by an analysis of the plan cost relative to industry and peer standards.

The 2014 Plan contains an “evergreen” provision pursuant to which as of the first day of each fiscal year, beginning with the fiscal year ended December 31, 2015 and continuing for each fiscal year until, and including, the fiscal year ending December 31, 2024, the number of shares authorized for issuance under the 2014 Plan is increased to the least of (i) 1,102,362 shares of of our common stock, (ii) four percent (4%) of the number of outstanding shares of our common stock on such date and (iii) an amount determined by our Board.


In connection with seeking the increase in the number of shares authorized for issuance under the 2014 Plan as described above, our Board also believes it is in the best interests of our stockholders to voluntarily amend the 2014 Plan to remove the evergreen provision. This means that the number of shares authorized for issuance under our 2014 Plan will no longer be subject to automatic increases each year during the remaining life of the plan. Instead, to the extent additional shares of our common stock are required for our 2014 Plan in the future, the prior approval of our stockholders will be required.
Summary of Material Provisions of 2014 Plan
The following summary of the material provisions of the 2014 Plan is qualified in its entirety by reference to the complete text of (x) the 2014 Plan Amendment and (y) the 2014 Plan, which are attached as Annex A to this Proxy Statement and incorporated by reference into this proposal. You are urged to read this proposal and the text of the 2014 Plan Amendment and the 2014 Plan in their entirety.
Eligible Participants. Awards may be granted under the 2014 Plan to individuals who are employees, officers or directors of ours or an affiliate, or consultants or advisers to us. As of April 26, 2019, approximately twenty-four employees, five non-employee directors and one non-employee consultant of ours or our subsidiaries or affiliates would have been eligible to participate.
Effective Date. The effective date of the 2014 Plan was February 11, 2014, which was immediately prior to the closing of the initial public offering of our common stock on the Nasdaq Global Market.
Term. The 2014 Plan will terminate automatically on February 11, 2024 (but any awards previously granted under the 2014 Plan prior to such date may extent beyond such date), unless it is earlier terminated by the Board.
Administration. The Compensation Committee of our Board administers the 2014 Plan and has authority to grant awards and to adopt, amend and repeal the administrative rules, guidelines and practices relating to the 2014 Plan and to construe and interpret the terms of the plan and any award agreements entered into under the plan. The Compensation Committee may correct any defect, supply any omission or reconcile any inconsistency in the 2014 Plan or any award under the plan in the manner and to the extent it deems expedient and it is the sole and final judge of such expediency. All decisions by the Compensation Committee are made in its sole discretion and are final and binding on all persons having or claiming any interest in the 2014 Plan or in any award under the plan.
To the extent permitted by applicable law, the Compensation Committee may delegate to one or more of our officers the power to grant options and other awards that constitute rights under Delaware law (subject to any limitations under the 2014 Plan) to our employees or officers and to exercise such other powers under the 2014 Plan as the Compensation Committee may determine, provided that the Compensation Committee must fix the terms of such awards to be granted by such officers (including the exercise price of such awards, which may include a formula by which the exercise price will be determined) and the maximum number of shares subject to such awards that the officers may grant. No officer will be authorized to grant such awards to any “executive officer” (as defined by Rule 3b-7 under the Exchange Act) or to any “officer” of the Company (as defined by Rule 16a-1 under the Exchange Act). The Compensation Committee may not delegate this authority to grant restricted stock, unless Delaware law then permits such delegation.
Amendment and Termination. The Board may amend, suspend or terminate the 2014 Plan or any portion of the 2014 Plan at any time, provided that no amendment that would require stockholder approval under the rules of the Nasdaq Stock Market may be made effective unless and until our stockholders approve such amendment. Unless otherwise specified in the amendment, any amendment to the 2014 Plan will apply to, and be binding on the holders of, all outstanding awards under the 2014 Plan at the time the amendment is adopted, provided our Board determines that such amendment, taking into account any related action, does not materially and adversely affect the rights of participants under the 2014 Plan.
The Compensation Committee may amend, modify or terminate any outstanding award granted under the 2014 Plan, subject to certain limitations set forth in the 2014 Plan, provided that the participant’s consent to any such action will be required unless the Compensation Committee determines that the action, taking into account any related action, does not materially and adversely affect the participant’s rights under the 2014 Plan, or the change is made in connection with a reorganization event.
Awards. The following type of awards may be made under the 2014 Plan, subject to the limitations set forth in the 2014 Plan: stock options, which may be either incentive stock options or non-qualified stock options; restricted stock awards; restricted stock units; stock appreciation rights, or SARs; and other stock-based awards.


The 2014 Plan provides that each award will be evidenced in such form (written, electronic or otherwise) as the Compensation Committee determines. Each award may contain terms and conditions in addition to those set forth in the 2014 Plan.
Shares Available for Issuance. The 2014 Plan presently has an aggregate amount of approximately 1,319,184 shares available for issuance. The 2014 Plan Amendment will increase the number of shares that may be issued under the 2014 Plan by 7,908,972 shares, for a total of approximately 9,228,156 shares, subject to adjustment in connection with certain changes in our capitalization, as described below.
Shares subject to an award granted under the 2014 Plan will be counted against the maximum number of shares of our common stock available for issuance under the plan as one share for every one share of our common stock subject to such an award. Shares subject to an award of SARs will be counted against the maximum number of shares available for issuance under the plan as one share for every one share of our common stock subject to such an award regardless of the number of shares of our common stock actually issued to settle such SARs upon the exercise of those rights. Awards that do not entitle a grantee to receive or purchase shares of our common stock and awards that are settled in cash will not be counted against the maximum number of shares of our common stock available for issuance under the plan. In the event SARs are granted in tandem with a stock option award for the same number of shares of common stock, and which provide that only one such award may be exercised, only the shares covered by the stock option award, and not the shares covered by the SAR, will be counted against the maximum number of shares available for issuance under the 2014 Plan, and the expiration of one in connection with the other’s exercise will not restore shares to the 2014 Plan.
Shares subject to an award granted under the 2014 Plan will again become available for issuance under the 2014 Plan in the same amount as such shares were counted against the share issuance limit if the award terminates by expiration, forfeiture, cancellation, or otherwise without the issuance of such shares (except as set forth below).
The number of shares of our common stock available for issuance under the 2014 Plan will not be increased by the number of shares of our common stock delivered (either by actual delivery, attestation, or net exercise) to us by a participant to (i) purchase shares of our common stock upon the exercise of an award or (ii) satisfy tax withholding obligations (including shares retained from the award creating the tax obligation).
Shares of our common stock to be issued under the 2014 Plan will be authorized and unissued shares or, to the extent permitted under applicable laws, shares of treasury stock.
Stock Options. An option granted under the 2014 Plan will become vested and exercisable at such times and under such conditions as the Compensation Committee may approve consistent with the terms of the 2014 Plan. No option may be exercisable more than 10 years after the option grant date. Our Compensation Committee may include in the option agreement provisions specifying the period during which an option may be exercised following termination of the grantee’s service. An option that the Compensation Committee intends to be an “incentive stock option” (as defined in Section 422 of the Code) may only be granted to employees of the Company or certain of our related corporations.
The exercise price per share of our common stock for each option granted under the 2014 Plan may not be less than 100% of the fair market value of a share of our common stock on the option grant date, provided that if the Compensation Committee approves the grant of an option with an exercise price to be determined on a future date, the exercise price will be not less than 100% of the fair market value on such future date.
Payment of the exercise price for shares purchased pursuant to the exercise of an option may be made in such forms as are approved by the Compensation Committee. These forms may include, in the Compensation Committee’s discretion, cash or check, an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to us sufficient funds to pay the exercise price and any required tax withholdings, shares of our common stock, net exercise, and payment of such other lawful consideration as the Compensation Committee may determine.
Restricted Stock and Restricted Stock Units. Restricted stock is an award of our common stock on which vesting restrictions are imposed that subject the underlying shares of our common stock to a substantial risk of forfeiture, as defined in Section 83 of the Code. A restricted stock unit is an award that represents a conditional right to receive shares of our common stock or cash in the future and that may be made subject to the same types of restrictions and risk of forfeiture as restricted stock. Subject to the provisions of the 2014 Plan, the Compensation Committee will determine the terms and conditions of each award of restricted stock and restricted stock units, including the restricted period for all or a portion of the award, the restrictions applicable to the award and the purchase price, if any, for the shares of our common stock subject to the award. A grantee of restricted stock will have all the rights of a stockholder, including the right to vote the shares and receive dividends, except (i) to the extent limited by the Compensation Committee and (ii) that unless otherwise provided for in an applicable award


agreement, dividends declared and paid by the Company with respect to shares of restricted stock will be paid to the holder of such restricted shares only if and when such restricted shares become free from the restrictions on transferability and forefeitability that apply to such restricted shares. Grantees of restricted stock units will have no voting or dividend rights or other rights associated with stock ownership, although the Compensation Committee may award dividend equivalent rights on such units. Dividend equivalents may be paid currently or credited to an account for the participants, may be settled in cash and/or shares of our common stock, and may be subject to the same restrictions on transfer and forfeitability as the restricted stock units with respect to which the dividend equivalents are paid. The Compensation Committee may, in its discretion, provide that settlement of restricted stock units will be deferred, on a mandatory basis or at the election of the participant in a manner that complies with Section 409A of the Code.
Stock Appreciation Rights. The Compensation Committee may grant SARs in conjunction with all or a part of any option or other award granted under the 2014 Plan, or without regard to any option or other award. The Compensation Committee will determine at the SAR grant date or thereafter the time or times at which and the circumstances under which a SAR may be exercised in whole or in part, the time or times at which and the circumstances under which a SAR will cease to be exercisable, the method of exercise, the method of settlement, the form of consideration payable in settlement, the method by which shares will be delivered or deemed delivered to grantees, and any other terms or conditions of any SAR. No SAR will be granted with a term in excess of 10 years.
Upon exercise of a SAR, the holder will be entitled to receive, in the specified form of consideration, the excess of the fair market value of one share of our common stock on the exercise date over the measurement price of the SAR, as determined by the Compensation Committee. The measurement price of a SAR may not be less than the fair market value of a share of our common stock on the grant date.
Other Stock-Based Awards.  The 2014 Plan authorizes other awards of shares of common stock and other awards that are valued in whole or in part by reference to, or are otherwise based on, shares of common stock or other property, having such terms and conditions as the Compensation Committee may determine, or Other Stock-Based Awards. Other Stock-Based Awards are available as a form of payment in the settlement of other awards granted under the 2014 Plan or as payment in lieu of compensation to which a participant under the plan is otherwise entitled. Other Stock-Based Awards may be paid in shares of common stock or cash, as the Compensation Committee may determine.
Limitation on Repricing of Stock Options and SARs.
With respect to stock options and SARs, unless such action is approved by our stockholders or otherwise permitted under the terms of the 2014 Plan as an equitable adjustment in connection with certain changes in capitalization and reorganization events as described below, we may not (i) amend any outstanding stock option or SAR granted under the plan to provide an exercise or measurement price per share that is lower than the then-current exercise or measurement price per share of such outstanding stock option or SAR, (ii) cancel any outstanding stock option or SAR (whether or not granted under the plan) and grant in substitution therefor new awards under the plan (other than certain substitute awards described in the plan) covering the same or a different number of shares of common stock and having an exercise or measurement price per share lower than the then-current exercise or measurement price per share of the cancelled stock option or SAR, (iii) cancel in exchange for a cash payment any outstanding stock option or SAR with an exercise or measurement price per share above the then-current fair market value of a share of our common stock or (iv) take any other action under the plan that constitutes a “repricing” within the meaning of the rules of Nasdaq.
Equitable Adjustments.    In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of our common stock other than an ordinary cash dividend, we are required by the 2014 Plan to make equitable adjustments (or make substitute awards, if applicable), in a manner determined by the Compensation Committee, to:
the number and class of securities available under the 2014 Plan; 

the share counting rules under the 2014 Plan; 

the number and class of securities and exercise price per share of each outstanding option; 

the share and per-share provisions and measurement price of each outstanding SAR; 

the number of shares and the repurchase price per share subject to each outstanding restricted stock award or restricted stock unit award; and 



the share and per-share related provisions and purchase price, if any, of any outstanding Other Stock-Based Award.

Upon a merger or other reorganization event (as defined in the 2014 Plan), the Compensation Committee, may, on such terms as it determines (except to the extent specifically provided otherwise in an applicable award agreement or other agreement between the plan participant and us), take any one or more of the following actions pursuant to the 2014 Plan, as to some or all outstanding awards, other than restricted stock awards:

provide that all outstanding awards will be assumed or substantially equivalent awards will be substituted by the successor corporation (or an affiliate thereof); 

upon written notice to a participant, provide that the participant’s unexercised awards will terminate immediately prior to the consummation of such transaction unless exercised by the participant within a specified period following the date of such notice; 

provide that outstanding awards will become exercisable, realizable or deliverable, or restrictions applicable to outstanding awards will lapse, in whole or in part, prior to or upon the reorganization event;

in the event of a reorganization event pursuant to which holders of our common stock will receive a cash payment for each share surrendered in the reorganization event, make or provide for a cash payment to the participants with respect to each award held by a participant equal to (1) the number of shares of our common stock subject to the vested portion of the award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such reorganization event) multiplied by (2) the excess, if any, of the cash payment for each share surrendered in the reorganization event over the exercise, measurement or purchase price of such award and any applicable tax withholdings, in exchange for the termination of such award; 

provide that, in connection with a liquidation or dissolution, awards convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings); or

any combination of the foregoing.
The Compensation Committee is not obligated by the 2014 Plan to treat all awards, all awards held by a participant or all awards of the same type, identically.
Upon the occurrence of a reorganization event other than a liquidation or dissolution, the repurchase and other rights under each outstanding restricted stock award will continue for the benefit of the successor company and will, unless the Compensation Committee may otherwise determine, apply to the cash, securities or other property which our common stock is converted into or exchanged for pursuant to the reorganization event, unless the Compensation Committee provided for the termination or deemed satisfaction of such repurchase or other rights under the restricted stock award agreement or any other agreement between the participant and us. Upon the occurrence of a reorganization event involving a liquidation or dissolution, all restrictions and conditions on each outstanding restricted stock award will automatically be deemed terminated or satisfied, unless otherwise provided in the agreement evidencing the restricted stock award or in any other agreement between the participant and us.
Transferability.  Subject to limited exceptions specified in the 2014 Plan, awards under the 2014 Plan may not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution or, other than in the case of an incentive stock option, pursuant to a qualified domestic relations order, and, during the life of the plan participant, are exercisable only by the plan participant.
Withholding. Participants must satisfy all applicable federal, state, and local or other income and employment tax withholding obligations before we will deliver stock certificates or otherwise recognize ownership of our common stock under an award. We may decide to satisfy the withholding obligations through additional withholding on salary or wages. If we elect not to or cannot withhold from other compensation, the participant must pay us the full amount, if any, required for withholding or have a broker tender to us cash equal to the withholding obligations. Payment of withholding obligations is due before we will issue any shares on exercise, vesting or release from forfeiture of an award or at the same time as payment of the exercise or purchase price unless we determine otherwise. If provided for in an award or approved by the Compensation Committee in its sole discretion, a participant may satisfy such tax obligations in whole or in part by delivery (either by actual delivery or attestation) of shares of our common stock, including shares retained from the award creating the tax obligation, valued at their fair market value, provided, however, except as otherwise provided by the Compensation Committee, that the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed our minimum statutory withholding


obligations. Shares used to satisfy tax withholding requirements cannot be subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements.
Acceleration.  The Compensation Committee may at any time provide that any award under the 2014 Plan will become immediately exercisable in whole or in part, free of some or all restrictions or conditions, or otherwise realizable in whole or in part, as the case may be.

Federal Income Tax Consequences
The following summarizes the federal income tax consequences of awards that may be granted under the 2014 Plan.
Incentive Stock Options.    An optionee who is granted an incentive stock option does not recognize taxable income at the time the option is granted or upon its exercise, although the exercise may subject the optionee to the alternative minimum tax. Upon a disposition of the shares more than two years after grant of the option and one year after exercise of the option, any gain or loss is treated as long-term capital gain or loss, and we will not be entitled to any deduction in connection with such disposition or the grant or exercise of the option. If these holding periods are not satisfied, the optionee recognizes ordinary income at the time of disposition equal to the difference between the exercise price and the lower of (i) the fair market value of the shares at the date of the option exercise or (ii) the sale price of the shares, and we will generally be entitled to a corresponding deduction. Any gain or loss recognized on such a premature disposition of the shares to the extent not recognized as taxable income as provided above, will be long-term or short-term capital gain or loss, depending on the holding period.
Nonqualified Stock Options.    An optionee does not recognize taxable income at the time he or she is granted a nonqualified stock option. Upon exercise, the optionee recognizes taxable income generally measured by the excess of the then fair market value of the shares over the exercise price. Any taxable income recognized in connection with an option exercise by our employee is subject to tax withholding by us. We are generally entitled to a deduction in the same amount as the ordinary income recognized by the optionee. Upon a disposition of such shares by the optionee, any difference between the sale price and the optionee's exercise price, to the extent not recognized as taxable income as provided above, is treated as long-term or short-term capital gain or loss, depending on the holding period.
Stock Appreciation Rights.    A holder of a SAR does not recognize taxable income at the time he or she is granted a SAR. Upon exercise, the participant will recognize ordinary income in an amount equal to the amount of cash received and the fair market value of the shares received, and if granted to an employee, tax withholding is generally due. Any additional gain or loss recognized upon any later disposition of the shares would be capital gain or loss, depending on the holding period. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant.
Restricted Stock.    A participant acquiring restricted stock generally will recognize ordinary income equal to the fair market value of the shares on the date the award vests. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. The participant may elect, pursuant to Section 83(b) of the Code, to recognize ordinary income on the date of acquisition of the shares, provided such election is made no later than 30 days after such date. The amount of ordinary income required to be recognized is an amount equal to the excess, if any, of the fair market value of the shares on the date of acquisition over the amount, if any, paid for such shares. Upon the sale of shares acquired pursuant to a restricted stock award for which an election pursuant to Section 83(b) of the Code has been made, any gain or loss, based on the difference between the sale price and the fair market value on the determination date, will be taxed as short term or long term capital gain or loss, depending on the holding period. Any taxable income recognized in connection with the grant of restricted stock by our employee is subject to tax withholding by us. The Company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant.
Restricted Stock Units.    A participant generally will recognize no income upon the grant of a restricted stock unit. Upon the settlement and/or payment of restricted stock units, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and the fair market value of any nonrestricted shares received. If the participant is an employee, such ordinary income generally is subject to withholding taxes. Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value will be taxed as capital gain or loss, depending on the holding period. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant.
Dividend Equivalents. A participant generally will recognize no income upon grant of a dividend equivalent. Upon settlement and/or payment of the dividend equivalent, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and the fair market value of any nonrestricted shares received. If the participant is an employee, such ordinary income generally is subject to withholding taxes. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant.


Other Stock-Based Awards. With respect to Other Stock-Based Awards granted under the 2014 Plan, when the participant receives payment in respect of the award, the amount of cash and/or the fair market value of any common stock or other property received will generally be ordinary income to the participant. If the participant is an employee, such ordinary income generally is subject to withholding taxes. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant.
Tax Withholding. Awards granted under the 2014 Plan to our employees will be subject to tax withholding as required by applicable laws upon the vesting of or other lapse of restrictions applicable to such award or upon the issuance of any shares upon the exercise of an award.

The foregoing is only a summary of the effect of federal income taxation upon award recipients and us with respect to the grant, vesting and/or exercise of awards granted under the 2014 Plan. Reference should be made to the applicable provisions of the Code. In addition, the summary does not purport to be complete, and does not discuss the tax consequences of the 2014 Plan participant's death or the provisions of the income tax laws of any municipality, state or foreign country in which the 2014 Plan participant may reside, nor does it discuss the Medicare tax on net investment income.
Proposed Amendment to the 2014 Plan

Our Board has approved, and recommends for adoption by our stockholders, the 2014 Plan Amendment to (i) increase the number of shares of common stock reserved for issuance under the 2014 Plan by 7,908,972 shares and (ii) eliminate the “evergreen” or automatic replenishment provision of the 2014 Plan pursuant to which the number of shares authorized for issuance under the 2014 Plan is automatically increased on an annual basis.
The effectiveness of the 2014 Plan Amendment is contingent upon stockholder approval. If our stockholders do not approve the amendment, the existing version of our 2014 Plan will remain in effect, unchanged.
Plan Benefits
On April 26, 2019, the closing price of our common stock on the Nasdaq Global Market was $1.10 per share. No awards have been approved for grant under the 2014 Plan contingent upon stockholder approval of the 2014 Plan Amendment. The granting of awards under the 2014 Plan is subject to the discretion of the Compensation Committee, and we cannot now determine with certainty the number or type of awards to be granted in the future to any particular person or group.
For illustrative purposes only, the following table sets forth (i) the number shares of our common stock subject to stock options granted under our 2014 Plan and (ii) the weighted average exercise price per share of these options, for all executive officers as a group, for all non-employee directors as a group and for all employees (excluding executive officers) as a group. There are no issued and outstanding restricted stock awards, RSUs or SARs under the 2014 Plan.

The unvested portion of Dr. DeCillis’ inducement award was forfeited as of October 3, 2017, which was the effective date of his resignation, and the remaining vested but unexercised options cancelled on January 3 2018. The unvested portion of Mr. Hurly’s inducement award was forfeited as of August 7, 2018, which was the date of his departure from us, and the remaining vested but unexercised options cancelled on November 7, 2018.
On August 7, 2018, in connection with the appointment of Dr. Cannell, we granted Dr. Cannell a non-statutory stock option to purchase 1,350,000 shares of our common stock. This grant was made in the form of an inducement equity award outside the 2014 Plan in accordance with Nasdaq Listing Rule 5635(c)(4). This stock option was granted with an effective grant date of August 7, 2018 and an exercise price of $1.60 per share (the closing price per share of our common stock on August 7, 2018). The stock option has a ten-year term and vests over a four-year period, with 25% percent of the shares underlying the stock option award vesting on the first anniversary of the date of grant and an additional 6.25% percent of the shares underlying the stock option vesting at the end of each successive three-month period following the one-year anniversary of the date of grant of the stock option, subject to Dr. Cannell’s continued service with us through the applicable vesting dates. The inducement equity award was approved by our Compensation Committee and was made as an inducement material to Dr. Cannell’s entering into employment with us in accordance with Nasdaq Listing Rule 5635(c)(4).
On December 3, 2018, in connection with the appointment of Dennis Kim, M.D., MPH as our Chief Medical Officer, we granted Dr. Kim a non-statutory stock option to purchase 425,000 shares of our common stock.

option was granted with an effective grant date of December 3, 2018 and an exercise price of $1.70 per share (the closing price per share of our common stock on December 3, 2018) as an inducement to Dr. Kim in connection with his employment.

SESEN BIO, INC.
2014 STOCK INCENTIVE PLAN
1.Purpose

The purpose of this 2014 Stock Incentive Plan (the “Plan”) of Sesen Bio, Inc., a Delaware corporation (the “Company”), is to advance the interests of the Company’s stockholders by enhancing the Company’s ability to attract, retain and motivate persons who are expected to make important contributions to the Company and by providing such persons with equity ownership opportunities and performance-based incentives that are intended to better align the interests of such persons with those of the Company’s stockholders. Except where the context otherwise requires, the term “Company” shall include any of the Company’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations thereunder (the “Code”) and any other business venture (including, without limitation, joint venture or limited liability company) in which the Company has a controlling interest, as determined by the Board of Directors of the Company (the “Board”).

2.Eligibility

All of the Company’s employees, officers and directors, as well as consultants and advisors to the Company (as such terms consultants and advisors are defined and interpreted for purposes of Form S-8 under the Securities Act of 1933, as amended (the “Securities Act”) (or any successor form)) are eligible to be granted Awards under the Plan. Each person who is granted an Award under the Plan is deemed a “Participant.” “Award” means Options (as defined in Section 5), SARs (as defined in Section 6), Restricted Stock (as defined in Section 7), Restricted Stock Units (as defined in Section 7) and Other Stock-Based Awards (as defined in Section 8).

3.Administration and Delegation

(a)Administration by Board of Directors. The Plan will be administered by the Board. The Board shall have authority to grant Awards and to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem advisable. The Board may construe and interpret the terms of the Plan and any Award agreements entered into under the Plan. The Board may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner and to the extent it shall deem expedient and it shall be the sole and final judge of such expediency. All decisions by the Board shall be made in the Board’s sole discretion and shall be final and binding on all persons having or claiming any interest in the Plan or in any Award.

(b)Appointment of Committees. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (each, a “Committee”). All references in the Plan to the “Board” shall mean the Board or a Committee of the Board or the officers referred to in Section 3(c) to the extent that the Board’s powers or authority under the Plan have been delegated to such Committee or officers.
(c)Delegation to Officers. To the extent permitted by applicable law, the Board may delegate to one or more officers of the Company the power to grant Options and other Awards that constitute rights under Delaware law (subject to any limitations under the Plan) to employees or officers of the Company and to exercise such other powers under the Plan as the Board may determine, provided that the Board shall fix the terms of such Awards to be granted by such officers (including the exercise price of such Awards, which may include a formula by which the exercise price will be determined) and the maximum number of shares subject to such Awards that the officers may grant; provided further, however, that no officer shall be authorized to grant such Awards to any “executive officer” of the Company (as defined by Rule 3b-7 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) or to any “officer” of the Company (as defined by Rule 16a-1 under the Exchange Act). The Board may not delegate authority under this Section 3(c) to grant Restricted Stock, unless Delaware law then permits such delegation.
4.Stock Available for Awards
(a)Number of Shares; Share Counting


(1)Authorized Number of Shares. Subject to adjustment under Section 9, Awards may be made under the Plan (any or all of which Awards may be in the form of Incentive Stock Options, as defined in Section 5(b)) for up to such number of shares of common stock, $0.001 par value per share, of the Company (the “Common Stock”) as is equal to the sum of:
(i)708,661 shares of Common Stock; plus
(ii)such additional number of shares of Common Stock (up to 1,352,154 shares) as is equal to the sum of (x) the number of shares of Common Stock reserved for issuance under the Company’s 2009 Stock Incentive Plan (the “Existing Plan”) that remain available for grant under the Existing Plan immediately prior to the closing of the Company’s initial public offering and (y) the number of shares of Common Stock subject to awards granted under the Existing Plan which awards expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right (subject, however, in the case of Incentive Stock Options to any limitations of the Code); plus
(iii)an annual increase to be added on the first day of each of the fiscal year, beginning with the fiscal year ending December 31, 2015 and continuing for each fiscal year until, and including, the fiscal year ending December 31, 2024, equal to the least of (i) 1,102,362 shares of Common Stock, (ii) 4% of the number of outstanding shares of Common Stock on such date or (iii) an amount determined by the Board.
Shares issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares.
(2)Share Counting. For purposes of counting the number of shares available for the grant of Awards under the Plan:
(i)all shares of Common Stock covered by SARs shall be counted against the number of shares available for the grant of Awards under the Plan; provided, however, that (i) SARs that may be settled only in cash shall not be so counted and (ii) if the Company grants an SAR in tandem with an Option for the same number of shares of Common Stock and provides that only one such Award may be exercised (a “Tandem SAR”), only the shares covered by the Option, and not the shares covered by the Tandem SAR, shall be so counted, and the expiration of one in connection with the other’s exercise will not restore shares to the Plan;
(ii)if any Award (i) expires or is terminated, surrendered or canceled without having been fully exercised or is forfeited in whole or in part (including as the result of shares of Common Stock subject to such Award being repurchased by the Company at the original issuance price pursuant to a contractual repurchase right) or (ii) results in any Common Stock not being issued (including as a result of an SAR that was settleable either in cash or in stock actually being settled in cash), the unused Common Stock covered by such Award shall again be available for the grant of Awards; provided, however, that (1) in the case of Incentive Stock Options, the foregoing shall be subject to any limitations under the Code, (2) in the case of the exercise of an SAR, the number of shares counted against the shares available under the Plan shall be the full number of shares subject to the SAR multiplied by the percentage of the SAR actually exercised, regardless of the number of shares actually used to settle such SAR upon exercise and (3) the shares covered by a Tandem SAR shall not again become available for grant upon the expiration or termination of such Tandem SAR; and
(iii)shares of Common Stock delivered (either by actual delivery, attestation, or net exercise) to the Company by a Participant to (i) purchase shares of Common Stock upon the exercise of an Award or (ii) satisfy tax withholding obligations (including shares retained from the Award creating the tax obligation) shall not be added back to the number of shares available for the future grant of Awards.
(b)Substitute Awards. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock of an entity, the Board may grant Awards in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof. Substitute Awards may be granted on such terms as the Board deems appropriate in the circumstances, notwithstanding any limitations on Awards contained in the Plan. Substitute Awards shall not count against the overall share limit set forth in Section 4(a), except as may be required by reason of Section 422 and related provisions of the Code.
5.Stock Options
(a)General. The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and


limitations applicable to the exercise of each Option, including conditions relating to applicable federal or state securities laws, as it considers necessary or advisable.
(b)Incentive Stock Options. An Option that the Board intends to be an “incentive stock option” as defined in Section 422 of the Code (an “Incentive Stock Option”) shall only be granted to employees of Sesen Bio, Inc., any of Sesen Bio, Inc.’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Code, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code, and shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. An Option that is not intended to be an Incentive Stock Option shall be designated a “Nonstatutory Stock Option.” The Company shall have no liability to a Participant, or any other party, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option or if the Company converts an Incentive Stock Option to a Nonstatutory Stock Option.
(c)Exercise Price. The Board shall establish the exercise price of each Option and specify the exercise price in the applicable Option agreement. The exercise price shall be not less than 100% of the fair market value per share of Common Stock, as determined by (or in a manner approved by) the Board (“Fair Market Value”), on the date the Option is granted; provided that if the Board approves the grant of an Option with an exercise price to be determined on a future date, the exercise price shall be not less than 100% of the Fair Market Value on such future date.
(d)Duration of Options. Each Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable option agreement; provided, however, that no Option will be granted with a term in excess of 10 years.
(e)Exercise of Options. Options may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic) approved by the Company, together with payment in full (in a manner specified in Section 5(f)) of the exercise price for the number of shares for which the Option is exercised. Shares of Common Stock subject to the Option will be delivered by the Company as soon as practicable following exercise.
(f)Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan shall be paid for as follows:
(1)in cash or by check, payable to the order of the Company;
(2)except as may otherwise be provided in the applicable Option agreement or approved by the Board, in its sole discretion, by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding;
(3)to the extent provided for in the applicable Option agreement or approved by the Board, in its sole discretion, by delivery (either by actual delivery or attestation) of shares of Common Stock owned by the Participant valued at their Fair Market Value, provided (i) such method of payment is then permitted under applicable law, (ii) such Common Stock, if acquired directly from the Company, was owned by the Participant for such minimum period of time, if any, as may be established by the Board in its discretion and (iii) such Common Stock is not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements;
(4)to the extent provided for in the applicable Nonstatutory Stock Option agreement or approved by the Board in its sole discretion, by delivery of a notice of “net exercise” to the Company, as a result of which the Participant would receive (i) the number of shares underlying the portion of the Option being exercised, less (ii) such number of shares as is equal to (A) the aggregate exercise price for the portion of the Option being exercised divided by (B) the Fair Market Value on the date of exercise;
(5)to the extent permitted by applicable law and provided for in the applicable Option agreement or approved by the Board, in its sole discretion, by payment of such other lawful consideration as the Board may determine; or
(6)by any combination of the above permitted forms of payment.
(g)Limitation on Repricing. Unless such action is approved by the Company’s stockholders, the Company may not (except as provided for under Section 9): (1) amend any outstanding Option granted under the Plan to provide an exercise price per share that is lower than the then-current exercise price per share of such outstanding Option, (2) cancel any


outstanding option (whether or not granted under the Plan) and grant in substitution therefor new Awards under the Plan (other than Awards granted pursuant to Section 4(b)) covering the same or a different number of shares of Common Stock and having an exercise price per share lower than the then-current exercise price per share of the cancelled option, (3) cancel in exchange for a cash payment any outstanding Option with an exercise price per share above the then-current Fair Market Value, or (4) take any other action under the Plan that constitutes a “repricing” within the meaning of the rules of the Nasdaq Stock Market (“Nasdaq”).
6.Stock Appreciation Rights
(a)General. The Board may grant Awards consisting of stock appreciation rights (“SARs”) entitling the holder, upon exercise, to receive an amount of Common Stock or cash or a combination thereof (such form to be determined by the Board) determined by reference to appreciation, from and after the date of grant, in the Fair Market Value of a share of Common Stock over the measurement price established pursuant to Section 6(b). The date as of which such appreciation is determined shall be the exercise date.
(b)Measurement Price. The Board shall establish the measurement price of each SAR and specify it in the applicable SAR agreement. The measurement price shall not be less than 100% of the Fair Market Value on the date the SAR is granted; provided that if the Board approves the grant of an SAR effective as of a future date, the measurement price shall be not less than 100% of the Fair Market Value on such future date.
(c)Duration of SARs. Each SAR shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable SAR agreement; provided, however, that no SAR will be granted with a term in excess of 10 years.
(d)Exercise of SARs. SARs may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic) approved by the Company, together with any other documents required by the Board.
(e)Limitation on Repricing. Unless such action is approved by the Company’s stockholders, the Company may not (except as provided for under Section 9): (1) amend any outstanding SAR granted under the Plan to provide a measurement price per share that is lower than the then-current measurement price per share of such outstanding SAR, (2) cancel any outstanding SAR (whether or not granted under the Plan) and grant in substitution therefor new Awards under the Plan (other than Awards granted pursuant to Section 4(b)) covering the same or a different number of shares of Common Stock and having an exercise or measurement price per share lower than the then-current measurement price per share of the cancelled SAR, (3) cancel in exchange for a cash payment any outstanding SAR with a measurement price per share above the then-current Fair Market Value, or (4) take any other action under the Plan that constitutes a “repricing” within the meaning of the rules of Nasdaq.
7.Restricted Stock; Restricted Stock Units
(a)General. The Board may grant Awards entitling recipients to acquire shares of Common Stock (“Restricted Stock”), subject to the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) from the recipient in the event that conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award. The Board may also grant Awards entitling the recipient to receive shares of Common Stock or cash to be delivered at the time such Award vests (“Restricted Stock Units”) (Restricted Stock and Restricted Stock Units are each referred to herein as a “Restricted Stock Award”).
(b)Terms and Conditions for All Restricted Stock Awards. The Board shall determine the terms and conditions of a Restricted Stock Award, including the conditions for vesting and repurchase (or forfeiture) and the issue price, if any.
(c)Additional Provisions Relating to Restricted Stock
(1)Dividends. Unless otherwise provided in the applicable Award agreement, any dividends (whether paid in cash, stock or property) declared and paid by the Company with respect to shares of Restricted Stock (“Accrued Dividends”) shall be paid to the Participant only if and when such shares become free from the restrictions on transferability and forfeitability that apply to such shares. Each payment of Accrued Dividends will be made no later than the end of the calendar year in which the dividends are paid to stockholders of that class of stock or, if later, the 15th day of the third month following the lapsing of the restrictions on transferability and the forfeitability provisions applicable to the underlying shares of Restricted Stock.


(2)Stock Certificates. The Company may require that any stock certificates issued in respect of shares of Restricted Stock, as well as dividends or distributions paid on such Restricted Stock, shall be deposited in escrow by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). At the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or if the Participant has died, to his or her Designated Beneficiary. “Designated Beneficiary” means (i) the beneficiary designated, in a manner determined by the Board, by a Participant to receive amounts due or exercise rights of the Participant in the event of the Participant’s death or (ii) in the absence of an effective designation by a Participant, the Participant’s estate.
(d)Additional Provisions Relating to Restricted Stock Units
(1)Settlement. Upon the vesting of and/or lapsing of any other restrictions (i.e., settlement) with respect to each Restricted Stock Unit, the Participant shall be entitled to receive from the Company such number of shares of Common Stock or (if so provided in the applicable Award agreement) an amount of cash equal to the Fair Market Value of such number of shares of Common Stock as set forth in the applicable Award agreement. The Board may, in its discretion, provide that settlement of Restricted Stock Units shall be deferred, on a mandatory basis or at the election of the Participant in a manner that complies with Section 409A of the Code.
(2)Voting Rights. A Participant shall have no voting rights with respect to any Restricted Stock Units.
(3)Dividend Equivalents. The Award agreement for Restricted Stock Units may provide Participants with the right to receive an amount equal to any dividends or other distributions declared and paid on an equal number of outstanding shares of Common Stock (“Dividend Equivalents”). Dividend Equivalents may be paid currently or credited to an account for the Participants, may be settled in cash and/or shares of Common Stock and may be subject to the same restrictions on transfer and forfeitability as the Restricted Stock Units with respect to which paid, in each case to the extent provided in the applicable Award agreement.
8.Other Stock-Based Awards
(a)General. Other Awards of shares of Common Stock, and other Awards that are valued in whole or in part by reference to, or are otherwise based on, shares of Common Stock or other property, may be granted hereunder to Participants (“Other Stock-Based-Awards”). Such Other Stock-Based Awards shall also be available as a form of payment in the settlement of other Awards granted under the Plan or as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock-Based Awards may be paid in shares of Common Stock or cash, as the Board shall determine.
(b)Terms and Conditions. Subject to the provisions of the Plan, the Board shall determine the terms and conditions of each Other Stock-Based Award, including any purchase price applicable thereto.
9.Adjustments for Changes in Common Stock and Certain Other Events
(a)Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of Common Stock other than an ordinary cash dividend, (i) the number and class of securities available under the Plan, (ii) the share counting rules set forth in Section 4(a), (iii) the number and class of securities and exercise price per share of each outstanding Option, (iv) the share and per-share provisions and the measurement price of each outstanding SAR, (v) the number of shares subject to and the repurchase price per share subject to each outstanding Restricted Stock Award and (vi) the share and per-share-related provisions and the purchase price, if any, of each outstanding Other Stock-Based Award, shall be equitably adjusted by the Company (or substituted Awards may be made, if applicable) in the manner determined by the Board. Without limiting the generality of the foregoing, in the event the Company effects a split of the Common Stock by means of a stock dividend and the exercise price of and the number of shares subject to an outstanding Option are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), then an optionee who exercises an Option between the record date and the distribution date for such stock dividend shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such Option exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record date for such stock dividend.
(b)Reorganization Events


(1)Definition. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any transfer or disposition of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange or other transaction or (c) any liquidation or dissolution of the Company.
(2)Consequences of a Reorganization Event on Awards Other than Restricted Stock
(i)In connection with a Reorganization Event, the Board may take any one or more of the following actions as to all or any (or any portion of) outstanding Awards other than Restricted Stock on such terms as the Board determines (except to the extent specifically provided otherwise in an applicable Award agreement or another agreement between the Company and the Participant): (i) provide that such Awards shall be assumed, or substantially equivalent Awards shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to a Participant, provide that all of the Participant’s unvested and/or unexercised Awards will terminate immediately prior to the consummation of such Reorganization Event unless exercised by the Participant (to the extent then exercisable) within a specified period following the date of such notice, (iii) provide that outstanding Awards shall become exercisable, realizable, or deliverable, or restrictions applicable to an Award shall lapse, in whole or in part prior to or upon such Reorganization Event, (iv) in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share surrendered in the Reorganization Event (the “Acquisition Price”), make or provide for a cash payment to Participants with respect to each Award held by a Participant equal to (A) the number of shares of Common Stock subject to the vested portion of the Award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such Reorganization Event) multiplied by (B) the excess, if any, of (I) the Acquisition Price over (II) the exercise, measurement or purchase price of such Award and any applicable tax withholdings, in exchange for the termination of such Award, (v) provide that, in connection with a liquidation or dissolution of the Company, Awards shall convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings) and (vi) any combination of the foregoing. In taking any of the actions permitted under this Section 9(b)(2), the Board shall not be obligated by the Plan to treat all Awards, all Awards held by a Participant, or all Awards of the same type, identically.
(ii)Notwithstanding the terms of Section 9(b)(2)(i), in the case of outstanding Restricted Stock Units that are subject to Section 409A of the Code: (i) if the applicable Restricted Stock Unit agreement provides that the Restricted Stock Units shall be settled upon a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5)(i), and the Reorganization Event constitutes such a “change in control event”, then no assumption or substitution shall be permitted pursuant to Section 9(b)(2)(i)(i) and the Restricted Stock Units shall instead be settled in accordance with the terms of the applicable Restricted Stock Unit agreement; and (ii) the Board may only undertake the actions set forth in clauses (iii), (iv) or (v) of Section 9(b)(2)(i) if the Reorganization Event constitutes a “change in control event” as defined under Treasury Regulation Section 1.409A-3(i)(5)(i) and such action is permitted or required by Section 409A of the Code; if the Reorganization Event is not a “change in control event” as so defined or such action is not permitted or required by Section 409A of the Code, and the acquiring or succeeding corporation does not assume or substitute the Restricted Stock Units pursuant to clause (i) of Section 9(b)(2)(i), then the unvested Restricted Stock Units shall terminate immediately prior to the consummation of the Reorganization Event without any payment in exchange therefor.
(iii)For purposes of Section 9(b)(2)(i)(i), an Award (other than Restricted Stock) shall be considered assumed if, following consummation of the Reorganization Event, such Award confers the right to purchase or receive pursuant to the terms of such Award, for each share of Common Stock subject to the Award immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the exercise or settlement of the Award to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event.
(3)Consequences of a Reorganization Event on Restricted Stock. Upon the occurrence of a Reorganization Event other than a liquidation or dissolution of the Company, the repurchase and other rights of the Company with respect to outstanding Restricted Stock shall inure to the benefit of the Company’s successor and shall, unless the Board determines otherwise, apply to the cash, securities or other property which the Common Stock was converted into or exchanged


for pursuant to such Reorganization Event in the same manner and to the same extent as they applied to such Restricted Stock; provided, however, that the Board may provide for termination or deemed satisfaction of such repurchase or other rights under the instrument evidencing any Restricted Stock or any other agreement between a Participant and the Company, either initially or by amendment. Upon the occurrence of a Reorganization Event involving the liquidation or dissolution of the Company, except to the extent specifically provided to the contrary in the instrument evidencing any Restricted Stock or any other agreement between a Participant and the Company, all restrictions and conditions on all Restricted Stock then outstanding shall automatically be deemed terminated or satisfied.
10.General Provisions Applicable to Awards
(a)Transferability of Awards. Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution or, other than in the case of an Incentive Stock Option, pursuant to a qualified domestic relations order, and, during the life of the Participant, shall be exercisable only by the Participant; provided, however, that the Board may permit or provide in an Award for the gratuitous transfer of the Award by the Participant to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the Participant and/or an immediate family member thereof if the Company would be eligible to use a Form S-8 under the Securities Act for the registration of the sale of the Common Stock subject to such Award to such proposed transferee; providedfurther, that the Company shall not be required to recognize any such permitted transfer until such time as such permitted transferee shall, as a condition to such transfer, deliver to the Company a written instrument in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of the Award. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees. For the avoidance of doubt, nothing contained in this Section 10(a) shall be deemed to restrict a transfer to the Company.
(b)Documentation. Each Award shall be evidenced in such form (written, electronic or otherwise) as the Board shall determine. Each Award may contain terms and conditions in addition to those set forth in the Plan.
(c)Board Discretion. Except as otherwise provided by the Plan, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award need not be identical, and the Board need not treat Participants uniformly.
(d)Termination of Status. The Board shall determine the effect on an Award of the disability, death, termination or other cessation of employment, authorized leave of absence or other change in the employment or other status of a Participant and the extent to which, and the period during which, the Participant, or the Participant’s legal representative, conservator, guardian or Designated Beneficiary, may exercise rights under the Award.
(e)Withholding. The Participant must satisfy all applicable federal, state, and local or other income and employment tax withholding obligations before the Company will deliver stock certificates or otherwise recognize ownership of Common Stock under an Award. The Company may decide to satisfy the withholding obligations through additional withholding on salary or wages. If the Company elects not to or cannot withhold from other compensation, the Participant must pay the Company the full amount, if any, required for withholding or have a broker tender to the Company cash equal to the withholding obligations. Payment of withholding obligations is due before the Company will issue any shares on exercise, vesting or release from forfeiture of an Award or at the same time as payment of the exercise or purchase price unless the Company determines otherwise. If provided for in an Award or approved by the Board in its sole discretion, a Participant may satisfy such tax obligations in whole or in part by delivery (either by actual delivery or attestation) of shares of Common Stock, including shares retained from the Award creating the tax obligation, valued at their Fair Market Value; provided, however, except as otherwise provided by the Board, that the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed the Company’s minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll taxes, that are applicable to such supplemental taxable income). Shares used to satisfy tax withholding requirements cannot be subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements.
(f)Amendment of Award. Except as otherwise provided in Sections 5(g) and 6(e) with respect to repricings and Section 11(d) with respect to actions requiring stockholder approval, the Board may amend, modify or terminate any outstanding Award, including but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonstatutory Stock Option. The Participant’s consent to such action shall be required unless (i) the Board determines that the action, taking into account any related action, does not materially and adversely affect the Participant’s rights under the Plan or (ii) the change is permitted under Section 9.


(g)Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove restrictions from shares previously issued or delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and regulations and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations.
(h)Acceleration. The Board may at any time provide that any Award shall become immediately exercisable in whole or in part, free of some or all restrictions or conditions, or otherwise realizable in whole or in part, as the case may be.
11.Miscellaneous
(a)No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award by virtue of the adoption of the Plan, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan, except as expressly provided in the applicable Award.
(b)No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant or Designated Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder of such shares.
(c)Effective Date and Term of Plan. The Plan shall become effective immediately prior to the closing of the Company’s initial public stock offering of its Common Stock on a U.S.-based stock exchange whereby the Company’s shares of Common Stock are offered for sale to the public (the “Effective Date”). No Awards shall be granted under the Plan after the expiration of 10 years from the Effective Date, but Awards previously granted may extend beyond that date.
(d)Amendment of Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time provided that (i) to the extent required by Section 162(m) of the Code, no Award granted to a Participant that is intended to comply with Section 162(m) of the Code after the date of such amendment shall become exercisable, realizable or vested, as applicable to such Award, unless and until the Company’s stockholders approve such amendment in the manner required by Section 162(m) of the Code; and (ii) no amendment that would require stockholder approval under the rules of the Nasdaq Stock Market may be made effective unless and until the Company’s stockholders approve such amendment. In addition, if at any time the approval of the Company’s stockholders is required as to any other modification or amendment under Section 422 of the Code or any successor provision with respect to Incentive Stock Options, the Board may not effect such modification or amendment without such approval. Unless otherwise specified in the amendment, any amendment to the Plan adopted in accordance with this Section 11(d) shall apply to, and be binding on the holders of, all Awards outstanding under the Plan at the time the amendment is adopted, provided the Board determines that such amendment, taking into account any related action, does not materially and adversely affect the rights of Participants under the Plan. No Award shall be made that is conditioned upon stockholder approval of any amendment to the Plan unless the Award provides that (i) it will terminate or be forfeited if stockholder approval of such amendment is not obtained within no more than 12 months from the date of grant and (2) it may not be exercised or settled (or otherwise result in the issuance of Common Stock) prior to such stockholder approval.
(e)Authorization of Sub-Plans (including Grants to non-U.S. Employees). The Board may from time to time establish one or more sub-plans under the Plan for purposes of satisfying applicable securities, tax or other laws of various jurisdictions. The Board shall establish such sub-plans by adopting supplements to the Plan containing (i) such limitations on the Board’s discretion under the Plan as the Board deems necessary or desirable or (ii) such additional terms and conditions not otherwise inconsistent with the Plan as the Board shall deem necessary or desirable. All supplements adopted by the Board shall be deemed to be part of the Plan, but each supplement shall apply only to Participants within the affected jurisdiction and the Company shall not be required to provide copies of any supplement to Participants in any jurisdiction which is not the subject of such supplement.
(f)Compliance with Section 409A of the Code. Except as provided in individual Award agreements initially or by amendment, if and to the extent (i) any portion of any payment, compensation or other benefit provided to a Participant pursuant to the Plan in connection with his or her employment termination constitutes “nonqualified deferred compensation” within the meaning of Section 409A of the Code and (ii) the Participant is a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, in each case as determined by the Company in accordance with its procedures, by which determinations the Participant (through accepting the Award) agrees that he or she is bound, such portion of the payment, compensation or


other benefit shall not be paid before the day that is six months plus one day after the date of “separation from service” (as determined under Section 409A of the Code) (the “New Payment Date”), except as Section 409A of the Code may then permit. The aggregate of any payments that otherwise would have been paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the Participant in a lump sum on such New Payment Date, and any remaining payments will be paid on their original schedule.
The Company makes no representations or warranty and shall have no liability to the Participant or any other person if any provisions of or payments, compensation or other benefits under the Plan are determined to constitute nonqualified deferred compensation subject to Section 409A of the Code but do not to satisfy the conditions of that section.
(g)Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director, officer, employee, or agent of the Company will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan, nor will such individual be personally liable with respect to the Plan because of any contract or other instrument he or she executes in his or her capacity as a director, officer, employee, or agent of the Company. The Company will indemnify and hold harmless each director, officer, employee, or agent of the Company to whom any duty or power relating to the administration or interpretation of the Plan has been or will be delegated, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Board’s approval) arising out of any act or omission to act concerning the Plan unless arising out of such person’s own fraud or bad faith.
(h)Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the State of Delaware, excluding choice-of-law principles of the law of such state that would require the application of the laws of a jurisdiction other than the State of Delaware.
