2010 Stock Incentive Plan

 Exhibit 10.5 
 AVEO PHARMACEUTICALS, INC. 
 2010 STOCK INCENTIVE PLAN 

 1. Purpose 
 The purpose of this 2010 Stock Incentive Plan (the “Plan”) of AVEO Pharmaceuticals, 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 promulgated 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 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 receives an Award under the Plan is deemed a “Participant”. Award means Options (as defined in Section 5), SARs (as defined in Section 7), Restricted Stock (as defined in
Section 8), Restricted Stock Units (as defined in Section 8) and Other Stock-Based Awards (as defined in Section 9) and Cash Based Awards (as defined in Section 9). 
 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 (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 or any of its present or future subsidiary corporations 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 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. Subject to adjustment under Section 10, Awards may be made under the Plan for up to the number of shares of
common stock, $.001 par value per share, of the Company (the “Common Stock”) (up to 10,000,000 shares) as is equal to the sum of (x) the number of shares of Common Stock reserved for issuance under the Company’s 2002 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 (as hereinafter defined) to any limitations of the Code). 
 If any Award expires or is terminated,
surrendered or canceled without having been fully exercised, 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), is settled in cash or otherwise results in any Common Stock not being issued, the unused Common Stock covered by such Award shall again be available for the grant of Awards under the Plan. Further, shares of Common
Stock delivered (either by actual delivery or attestation) to the Company by a Participant to exercise an Award or to satisfy any applicable tax withholding obligation (including shares retained from the Award creating the tax obligation) shall be
added to the number of shares of Common Stock available for the grant of Awards under the Plan. However, in the case of Incentive Stock Options, the foregoing provisions shall be subject to any limitations under the Code. Shares issued under the
Plan may consist in whole or in part of authorized but unissued shares or treasury shares. 
  

 -2- 

 (b) Per-Participant Limit. Subject to adjustment under Section 10, the maximum
number of shares of Common Stock with respect to which Awards may be granted to any Participant under the Plan shall be 1,000,000 per fiscal year. For purposes of the foregoing limit, the combination of an Option (as hereinafter defined) in
tandem with an SAR shall be treated as a single Award. The per-Participant limit described in this Section 4(b) shall be construed and applied consistently with Section 162(m) of the Code or any successor provision thereto, and the
regulations thereunder (“Section 162(m)”). 
 (c) 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. An Option that is not intended to be an Incentive Stock Option shall be designated a “Nonqualified Stock Option”. 
 (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 AVEO Pharmaceuticals, Inc., any of AVEO Pharmaceuticals, 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. 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 for any action taken by the Board, or if the Company converts an Incentive Stock Option to a Nonqualified 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 (as defined below) 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. 
  

 -3- 

 (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 that no Option shall 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 in electronic form) approved by the Company together with payment in
full (in the 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” (determined in the manner set forth below), 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 Nonqualified 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 (i) delivery of a promissory note of the Participant to the Company on terms determined by the Board, or (ii) payment of such other lawful consideration as the Board may determine; or

 (6) by any combination of the above permitted forms of payment. 
  

 -4- 

 (g) Fair Market Value. Fair Market Value of a share of Common Stock for purposes of
the Plan will be determined as follows: 
 (1) if the Common Stock trades on a national securities exchange, the
closing sale price (for the primary trading session) on the date of grant; or 
 (2) if the Common Stock does not
trade on any such exchange, the average of the closing bid and asked prices as reported by an authorized OTCBB market data vendor as listed on the OTCBB website (otcbb.com) on the date of grant; or 
 (3) if the Common Stock is not publicly traded, the Board will determine the Fair Market Value for purposes of the Plan using
any measure of value it determines to be appropriate (including, as it considers appropriate, relying on appraisals) in a manner consistent with the valuation principles under Code Section 409A, except as the Board or Committee may expressly
determine otherwise. 
 For any date that is not a trading day, the Fair Market Value of a share of Common Stock for such date
will be determined by using the closing sale price or average of the bid and asked prices, as appropriate, for the immediately preceding trading day and with the timing in the formulas above adjusted accordingly. The Board can substitute a
particular time of day or other measure of “closing sale price” or “bid and asked prices” if appropriate because of exchange or market procedures or can, in its sole discretion, use weighted averages either on a daily basis or
such longer period as complies with Code Section 409A. 
 The Board has sole discretion to determine the Fair Market Value
for purposes of this Plan, and all Awards are conditioned on the participants’ agreement that the Administrator’s determination is conclusive and binding even though others might make a different determination. 
 6. Director Options. 
 (a)
Initial Grant. Upon the commencement of service on the Board by any individual who is not then an employee of the Company or any subsidiary of the Company, the Company shall automatically be granted a Nonqualified Stock Option to purchase
75,000 shares of Common Stock (subject to adjustment under Section 10). 
 (b) Annual Grant. On the date of each
annual meeting of stockholders of the Company, each member of the Board of Directors of the Company who is both serving as a director of the Company immediately prior to and immediately following such annual meeting and who is not then an employee
of the Company or any of its subsidiaries, shall automatically be granted a Nonqualified Stock Option to purchase 50,000 shares of Common Stock (subject to adjustment under Section 10); provided, however, that a director shall not be eligible
to receive an Option grant under this Section 6(b) until such director has served on the Board for at least six months. 
  

 -5- 

 (c) Terms of Director Options. Options granted under this Section 6 shall
(i) have an exercise price equal to 100% of the Fair Market Value of the Common Stock on the date the Option is granted, (ii) vest in full on the first anniversary of the date of grant provided that the individual is serving on the Board
on such date (or in the case of an Option granted under Section 6(b), if earlier, on the date that is one business day prior to date of the Company’s next annual meeting), provided that no additional vesting shall take place after the
Participant ceases to serve as a director and further provided that the Board may provide for accelerated vesting in the case of death, disability, a Change in Control Event (as defined below), attainment of mandatory retirement age or retirement
following at least 10 years of Board service, (iii) expire on the earlier of 10 years from the date of grant or three months following cessation of service on the Board and (iv) contain such other terms and conditions as the Board shall
determine. 
 (d) Board Discretion. The Board retains the specific authority to provide for different vesting provisions
and conditions than those set forth in Section 6(c), to increase or decrease from time to time the number of shares subject to Options granted under this Section 6 and to issue SARs, Restricted Stock Awards, or Other Stock-Based Awards in
lieu of some or all of the Options otherwise issuable under this Section 6. 
 7. 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 determined in whole or in part 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 7(c). The date as of which such appreciation is determined shall be the exercise date. 
 (b) Grants. SARs
may be granted in tandem with, or independently of, Options granted under the Plan. 
 (1) Tandem
Awards. When SARs are expressly granted in tandem with Options, (i) the SAR will be exercisable only at such time or times, and to the extent, that the related Option is exercisable (except to the extent designated by the Board in
connection with a Reorganization Event or a Change in Control Event) and will be exercisable in accordance with the procedure required for exercise of the related Option; (ii) the SAR will terminate and no longer be exercisable upon the
termination or exercise of the related Option, except to the extent designated by the Board in connection with a Reorganization Event or a Change in Control Event and except that a SAR granted with respect to less than the full number of shares
covered by an Option will not be reduced until the number of shares as to which the related Option has been exercised or has terminated exceeds the number of shares not covered by the SAR; (iii) the Option will terminate and no longer be
exercisable upon the exercise of the related SAR; and (iv) the SAR will be transferable only with the related Option. 
 (2) Independent SARs. A SAR not expressly granted in tandem with an Option will become exercisable at such time or times, and on such conditions, as the Board may specify in the SAR Award.

  

 -6- 

 (c) 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 a SAR effective as of a future date, the
measurement price shall be not be less than 100% of the Fair Market Value on such future date. 
 (d) 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 that no SAR will be granted with a term in excess of 10 years. 
 (e) Exercise of SARs. SARs may be exercised by delivery to the Company of a notice of exercise in a form (which may be in electronic
form) approved by the Company, together with any other documents required by the Board. 
 8. 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 any 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

  

 -7- 

 
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 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 (the “Designated Beneficiary”). In the absence of an effective designation by a
Participant, “Designated Beneficiary” shall mean 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 one share of Common Stock or an amount of cash equal to the Fair Market Value of one share of Common Stock, as
provided 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 Code
Section 409A. 
 (2) Voting Rights. A Participant shall have no voting rights with respect to any
Restricted Stock Units. 
 (3) Dividend Equivalents. To the extent provided by the Board, in its sole
discretion, a grant of 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, as determined by the Board in its sole discretion, subject in each case to such terms and conditions as the Board shall establish, in each case to be set forth in the applicable Award agreement.

 9. Other Stock-Based and Cash-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”), including without limitation Awards entitling recipients to receive shares of Common Stock to be delivered in the future. 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. The Company may also grant Performance Awards or other Awards denominated in cash rather than shares of Common Stock (“Cash-Based Awards”). 
  

 -8- 

 (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 or Cash-Based Award, including any purchase price applicable thereto. 
 10.
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 this Plan, (ii) the share counting rules and per-Participant limit set forth in Section 4(a) and 4(b), (iii) the number and class of
securities and exercise price per share of each outstanding Option and each Option issuable under Section 6, (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.

	 	(2)	Effect on Options 

  

	 	(a)	Reorganization Event. Upon the occurrence of a Reorganization Event (regardless of whether such event also constitutes a Change in Control Event), or the
execution by the Company of any agreement with respect to a Reorganization Event (regardless of whether such event will result in a Change in Control Event), the Board shall provide that all outstanding Options shall be assumed, or equivalent
options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof); provided that if such Reorganization Event also constitutes a Change in Control Event, except to the extent specifically provided to the contrary in
the instrument evidencing any Option or any other agreement between a Participant and the Company such assumed or substituted options that are held by employees of the Company shall become immediately exercisable in full if, on or prior to the first
anniversary of the date of the consummation of the 

  

 -12- 

 Reorganization Event, the Participant’s employment with the Company or the acquiring
or succeeding corporation is terminated without Cause by the Company or the acquiring or succeeding corporation. For purposes hereof, an Option shall be considered to be assumed if, following consummation of the Reorganization Event, the Option
confers the right to purchase, for each share of Common Stock subject to the Option 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 of Options to consist solely of common stock of the acquiring or succeeding corporation (or an
affiliate thereof) equivalent in value (as determined by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event. 
 Notwithstanding the foregoing, if the acquiring or succeeding corporation (or an affiliate thereof) does not agree to
assume, or substitute for, such Options, or in the event of a liquidation or dissolution of the Company, the Board shall, upon written notice to the Participants, provide that all then unexercised Options will become exercisable in full as of a
specified time prior to the Reorganization Event and will terminate immediately prior to the consummation of such Reorganization Event, except to the extent exercised by the Participants before the consummation of such Reorganization Event;
provided, however, that 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 of Common Stock surrendered pursuant to such Reorganization Event
(the “Acquisition Price”), then the Board may instead provide that all outstanding Options shall terminate upon consummation of such Reorganization Event and that each Participant shall receive, in exchange therefor, a cash payment equal
to the amount (if any) by which (A) the Acquisition Price multiplied by the number of shares of Common Stock subject to such outstanding Options (whether or not then exercisable), exceeds (B) the aggregate exercise price of such Options
and any applicable tax withholdings. 
  

 -13- 

	 	(b)	Change in Control Event that is not a Reorganization Event. Upon the occurrence of a Change in Control Event that does not also constitute a Reorganization
Event, except to the extent specifically provided to the contrary in the instrument evidencing any Option or any other agreement between a Participant and the Company, each such Option that is held by an employee of the Company shall be immediately
exercisable in full if, on or prior to the first anniversary of the date of the consummation of the Change in Control Event, the Participant’s employment with the Company or the acquiring or succeeding corporation is terminated without Cause by
the Company or the acquiring or succeeding corporation. 

  

	 	(3)	Effect on Restricted Stock Awards 

  

	 	(a)	Reorganization Event that is not a Change in Control Event. Upon the occurrence of a Reorganization Event that is not a Change in Control Event, the repurchase
and other rights of the Company under each outstanding Restricted Stock Award shall inure to the benefit of the Company’s successor and shall 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 the Common Stock subject to such Restricted Stock Award. 

  

	 	(b)	Change in Control Event. Upon the occurrence of a Change in Control Event (regardless of whether such event also constitutes a Reorganization Event), except to
the extent specifically provided to the contrary in the instrument evidencing any Restricted Stock Award or any other agreement between a Participant and the Company, each such Restricted Stock Award held by employees of the Company shall
immediately become free from all conditions or restrictions if, on or prior to the first anniversary of the date of the consummation of the Change in Control Event, the Participant’s employment with the Company or the acquiring or succeeding
corporation is terminated without Cause by the Company or the acquiring or succeeding corporation. 

  

	 	(4)	Effect on Stock Appreciation Rights and Other Stock Unit Awards 

 The Board may specify in an Award at the time of the grant the effect of a Reorganization Event and Change in Control Event on any SAR and Other Stock Unit Award.

 11. General Provisions Applicable to Awards 
 (a) Transferability of Awards. Except as the Board may otherwise determine or provide in an Award, 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. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees.

 (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, if the
Company so requires, 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. 
  

 -15- 

 (f) Amendment of Award. 
 (1) 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 Nonqualified 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 10 hereof. 
 (2) Notwithstanding anything in the Plan to the contrary, the Committee may, without stockholder approval, (i) amend any
outstanding Award 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 Award, (ii) cancel any outstanding Award (whether or not granted under the Plan)
and grant in substitution therefor new Awards under the Plan 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 Award,
(iii) take any action that is treated as a “repricing” under generally accepted accounting principles, or (iv) take any other action that has the same effect as any of the foregoing. 
 (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 full or in part, free of
some or all restrictions or conditions, or otherwise realizable in full or in part, as the case may be. 
 (i) Performance
Awards. 
 (1) Grants. Restricted Stock Awards and Other Stock-Based Awards under the Plan may be made
subject to the achievement of performance goals pursuant to this Section 11(i) (“Performance Awards”), subject to the limit in Section 4(b) on shares covered by such grants. 
 (2) Cash Payments. Performance Awards can also provide for cash payments of up to $1,000,000 per fiscal year per
individual. 
 (3) Committee. Grants of Performance Awards to any Covered Employee intended to qualify as
“performance-based compensation” under Section 162(m) (“Performance-Based Compensation”) shall be made only by a Committee (or subcommittee of a Committee) comprised solely of two or more directors eligible to serve on a
committee making Awards qualifying as “performance-based compensation” under Section 162(m). In the case of such Awards granted to Covered Employees, references to the Board or to a Committee shall be deemed to be references to such
Committee or subcommittee. “Covered Employee” shall mean any person who is, or whom the Committee, in its discretion, determines may be, a “covered employee” under Section 162(m)(3) of the Code. 
  

 -16- 

 (4) Performance Measures. For any Award that is intended to qualify
as Performance-Based Compensation, the Committee shall specify that the degree of granting, vesting and/or payout shall be subject to the achievement of one or more objective performance measures established by the Committee, which shall be based on
the relative or absolute attainment of any combination of the following: (i) the entry into an arrangement or agreement with a third party for the development, commercialization, marketing or distribution of products, services or technologies, or
for conducting a research program to discover and develop a product, service or technology, and/or the achievement of milestones under such arrangement or agreement, including events that trigger an obligation or payment right; (ii) achievement of
domestic and international regulatory milestones, including the submission of filings required to advance products, services and technologies in clinical development and the achievement of approvals by regulatory authorities relating to the
commercialization of products, services and technologies; (iii) the achievement of discovery, preclinical and clinical stage scientific objectives, discoveries or inventions for products, services and technologies under research and development;
(iv) the entry into or completion of a phase of clinical development for any product, service or technology, such as the entry into or completion of phase 1, 2 and/or 3 clinical trials; (v) the consummation of debt or equity financing transactions,
or acquisitions of business, technologies and assets; (vi) new product or service releases; (vii) the achievement of qualitative or quantitative performance measures set forth in operating plans approved by the Board from time to time; and/or (viii)
specified levels of product sales, net income, earnings before or after discontinued operations, interest, taxes, depreciation and/or amortization, operating profit before or after discontinued operations and/or taxes, sales, sales growth, earnings
growth, cash flow or cash position, gross margins, stock price, market share, return on sales, assets, equity or investment, (ix) improvement of financial ratings, (x) achievement of balance sheet or income statement objectives, (xi) total
stockholder return and/or (xii) other comparable measures of financial and operational performance. Such goals may reflect, as applicable, absolute entity or business unit performance or a relative comparison to the performance of a peer group of
entities or other external measure of the selected performance criteria and may be absolute in their terms or measured against or in relationship to other companies comparably, similarly or otherwise situated. The Committee may specify that such
performance measures shall be adjusted to exclude any one or more of (i) extraordinary items, (ii) gains or losses on the dispositions of discontinued operations, (iii) the cumulative effects of changes in accounting principles, (iv) the writedown
of any asset, and (v) charges for restructuring and rationalization programs. Such performance measures: (i) may vary by Participant and may be different for different Awards; (ii) may be particular to a Participant or the department, branch, line
of business, subsidiary or other unit in which the Participant works and may cover such period as may be specified by the Committee; and (iii) shall be set by the Committee within the time period prescribed by, and shall otherwise comply with the
requirements of, Section 162(m). Awards that are not intended to qualify as Performance-Based Compensation may be based on these or such other performance measures as the Board may determine.  
 (5) Adjustments. Notwithstanding any provision of the Plan, with respect to any Performance Award that is intended to
qualify as Performance-Based Compensation, the Committee may adjust downwards, but not upwards, the cash or number of Shares payable pursuant to such Award, and the Committee may not waive the achievement of the applicable performance measures
except in the case of the death or disability of the Participant or a Change in Control Event. 
 (6)
Other. The Committee shall have the power to impose such other restrictions on Performance Awards as it may deem necessary or appropriate to ensure that such Awards satisfy all requirements for Performance-Based Compensation. 
 12. 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. 
  

 -17- 

 (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 on the date the Plan is approved by the Company’s
stockholders (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), no Award granted to a Participant that is intended to comply with Section 162(m) after the date of such amendment shall become exercisable, realizable or vested, as applicable to such
Award, unless and until such amendment shall have been approved by the Company’s stockholders if required by Section 162(m) (including the vote required under Section 162(m)); and (ii) no amendment that would require stockholder
approval under the rules of the NASDAQ Stock Market may be made effective unless and until such amendment shall have been approved by the Company’s stockholders. 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 12(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. 
 (e) Provisions for Foreign Participants. The Board may modify Awards granted to Participants who are foreign
nationals or employed outside the United States or establish subplans or procedures under the Plan to recognize differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee
benefit or other matters. 
 (f) Compliance with Code Section 409A. Except as provided in individual Award
agreements initially or by amendment, if and to the extent any portion of any payment, compensation or other benefit provided to a Participant in connection with his or her employment termination is determined to constitute “nonqualified
deferred compensation” within the meaning of Section 409A of the Code and the Participant is a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, as determined by the Company in accordance with its procedures, by
which determination the Participant (through accepting the Award) agrees that he or she is

  

 -18- 

 
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 Code Section 409A (the “New Payment Date”), except as Code Section 409A may then permit. 
 The Company makes no representation 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 satisfy the conditions of that section. 
 (g)
Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director, officer, other 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, other employee, or agent of the Company. The Company will indemnify and hold harmless each director, officer, other 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 this 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 such state.

 -19-2010 Employee Stock Purchase Plan

 Exhibit 10.17 
 AVEO PHARMACEUTICALS, INC. 
 2010 EMPLOYEE STOCK PURCHASE PLAN

 The purpose of this Plan is to provide eligible employees of AVEO Pharmaceuticals, Inc. (the “Company”) and certain
of its subsidiaries with opportunities to purchase shares of the Company’s common stock, $.001 par value (the “Common Stock”), commencing on July 1, 2010. This Plan is intended to qualify as an “employee stock purchase
plan” as defined in Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated thereunder, and shall be interpreted consistent therewith. 
 1. Administration. The Plan will be administered by the Company’s Board of Directors (the “Board”) or by a Committee
appointed by the Board (the “Committee”). The Board or the Committee has authority to make rules and regulations for the administration of the Plan and its interpretation and decisions with regard thereto shall be final and conclusive.

 2. Shares Authorized for Issuance. One Million (1,000,000) shares of Common Stock in the aggregate have been
approved for issuance under the Plan. 
 3. Eligibility. All employees of the Company, including Directors who are
employees, and all employees of any subsidiary of the Company (as defined in Section 424(f) of the Code) designated by the Board or the Committee from time to time (a “Designated Subsidiary”), are eligible to participate in any one or
more of the offerings of Options (as defined in Section 10) to purchase Common Stock under the Plan provided that: 
 (a)
they are customarily employed by the Company or a Designated Subsidiary for more than 20 hours a week and for more than five months in a calendar year; and 
 (b) they have been employed by the Company or a Designated Subsidiary for at least 6 months prior to enrolling in the Plan; and 
 (c) they are employees of the Company or a Designated Subsidiary on the first day of the applicable Plan Period (as defined below).

 No employee may be granted an option hereunder if such employee, immediately after the option is granted, owns 5% or
more of the total combined voting power or value of the stock of the Company or any subsidiary. For purposes of the preceding sentence, the attribution rules of Section 424(d) of the Code shall apply in determining the stock ownership
of an employee, and all stock which the employee has a contractual right to purchase shall be treated as stock owned by the employee. 
 The Company retains the discretion to determine which eligible employees may participate in an Offering pursuant to and consistent with Treasury Regulation Sections 1.423-2(e) and (f). 
  

 - 1 - 

 4. Offerings. The Company will make one or more offerings (“Offerings”) to
employees to purchase stock under this Plan. Unless otherwise provided by the Board or the Committee as provided herein, Offerings will begin on July 1, 2010 and on each subsequent January 1 and July 1, or the first business day
thereafter (the “Offering Commencement Dates”) and each Offering Commencement Date will begin a six month period (a “Plan Period”) during which payroll deductions will be made and held for the purchase of Common Stock at the end
of the Plan Period as prescribed hereunder. The Board or the Committee may, at its discretion, change the date on which Plan Periods may commence and may choose a different Plan Period of twenty-four (24) months or less for such Offerings.

 5. Participation. An employee eligible on the Offering Commencement Date of any Offering may participate in such
Offering by completing and forwarding a payroll deduction authorization form to the employee’s appropriate payroll office or otherwise completing the enrollment procedures as required, at least 7 days prior to the applicable Offering
Commencement Date. The enrollment procedure will authorize a regular payroll deduction from the Compensation received by the employee during the Plan Period. Unless an appropriate change is made in the employee’s enrollment in the Plan as
required or the employee withdraws from the Plan, his or her deductions and purchases will continue at the same rate for future Offerings under the Plan as long as the Plan remains in effect. The term “Compensation” means the amount of
money reportable on the employee’s Federal Income Tax Withholding Statement, excluding overtime, shift premium, incentive or bonus awards, allowances and reimbursements for expenses such as relocation allowances for travel expenses, income or
gains associated with the grant or vesting of restricted stock, income or gains on the exercise of Company stock options or stock appreciation rights, and similar items, whether or not shown on the employee’s Federal Income Tax Withholding
Statement, but including, in the case of salespersons, sales commissions to the extent determined by the Board or the Committee. 
 6. Deductions. The Company will maintain payroll deduction accounts for all participating employees. With respect to any Offering made under this Plan, an employee may authorize a payroll deduction in any dollar amount up to a
maximum of 15% of the Compensation he or she receives during the Plan Period or such shorter period during which deductions from payroll are made. The Board or the Committee may, at its discretion, designate a lower maximum contribution rate. The
minimum payroll deduction is such percentage of compensation as may be established from time to time by the Board or the Committee. 
 7. Deduction Changes. An employee may decrease or discontinue his or her payroll deduction once during any Plan Period, by filing a new payroll deduction authorization form or otherwise changing the payroll deduction in
accordance with Plan procedures. However, an employee may not increase his or her payroll deduction during a Plan Period. If an employee elects to discontinue his or her payroll deductions during a Plan Period, but does not elect to withdraw
his or her funds pursuant to Section 9 hereof, funds deducted prior to his or her election to discontinue will be applied to the purchase of Common Stock on the Exercise Date (as defined below). 
 8. Interest. Interest will not be paid on any employee accounts, except to the extent that the Board or the Committee, in its
sole discretion, elects to credit employee accounts with interest at such per annum rate as it may from time to time determine. 
  

 - 2 - 

 9. Withdrawal of Funds. An employee may at any time prior to the close of business on
the last business day in a Plan Period and for any reason permanently draw out the balance accumulated in the employee’s account and thereby withdraw from participation in an Offering. Partial withdrawals are not permitted. The employee may not
begin participation again during the remainder of the Plan Period. The employee may participate in any subsequent Offering in accordance with terms and conditions established by the Board or the Committee. 
 10. Purchase of Shares. 
 (a) Number of Shares. On the Offering Commencement Date of each Plan Period, the Company will grant to each eligible employee who is then a participant in the Plan an option (an “Option”)
to purchase on the last business day of such Plan Period (the “Exercise Date”) at the applicable purchase price (the “Option Price”) up to a whole number of shares of Common Stock determined by multiplying $2,083 by the number of
full months in the Plan Period and dividing the result by the closing price (as defined below) on the Offering Commencement Date (the “Option Grant Formula”); provided, however, that no employee may be granted an Option which permits his
or her rights to purchase Common Stock under this Plan and any other employee stock purchase plan (as defined in Section 423(b) of the Code) of the Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the fair market value
of such Common Stock (determined at the date such Option is granted) for each calendar year in which the Option is outstanding at any time. 
 (b) Option Price. The Board or the Committee shall determine the Option Price for each Plan Period, including whether such Option Price shall be determined based on the lesser of (i) the
closing price of the Common Stock on the first business day of the Plan Period or (ii) the Exercise Date, or shall be based solely on the closing price of the Common Stock on the Exercise Date; provided, however, that such Option Price shall be
at least 85% of the applicable closing price. In the absence of a determination by the Board or the Committee, the Option Price will be 85% of the lesser of the closing price of the Common Stock on the (i) first business day of the Plan Period
or (ii) the Exercise Date. The closing price shall be (a) the closing price on any national securities exchange on which the Common Stock is listed, (b) the closing price of the Common Stock on the Nasdaq Global Market or (c) the
average of the closing bid and asked prices in the over-the-counter-market, whichever is applicable, as published in The Wall Street Journal; provided that, with respect to the first Plan Period, the closing price on the Offering Commencement
Date shall be the initial public offering price provided for in the underwriting agreement entered into by the Company in connection with the IPO. If no sales of Common Stock were made on such a day, the price of the Common Stock for purposes of
clauses (a) and (b) above shall be the reported price for the next preceding day on which sales were made. 
 (c)
Exercise of Option. Each employee who continues to be a participant in the Plan on the Exercise Date shall be deemed to have exercised his or her Option at the Option Price on such date and shall be deemed to have purchased from the Company
the number of whole shares of Common Stock reserved for the purpose of the Plan that his or her accumulated payroll deductions on such date will pay for, but not in excess of the maximum number determined in the manner set forth above. 

(d) Return of Unused Payroll Deductions. Any balance remaining in an employee’s payroll deduction account at the end of a
Plan Period will be automatically refunded to the employee, except that any balance which is less than the purchase price of one share of Common Stock will be carried forward into the employee’s payroll deduction account for the following
Offering, unless the employee elects not to participate in the following Offering under the Plan, in which case the balance in the employee’s account shall be refunded. 
  

 - 3 - 

 11. Issuance of Certificates. Certificates representing shares of Common Stock
purchased under the Plan may be issued only in the name of the employee, in the name of the employee and another person of legal age as joint tenants with rights of survivorship, or (in the Company’s sole discretion) in the name of a brokerage
firm, bank, or other nominee holder designated by the employee. The Company may, in its sole discretion and in compliance with applicable laws, authorize the use of book entry registration of shares in lieu of issuing stock certificates. 

12. Rights on Retirement, Death or Termination of Employment. In the event of a participating employee’s termination of
employment prior to the last business day of a Plan Period, no payroll deduction shall be taken from any pay due and owing to an employee and the balance in the employee’s account shall be paid to the employee or, in the event of the
employee’s death, (a) to a beneficiary previously designated in a revocable notice signed by the employee (with any spousal consent required under state law) or (b) in the absence of such a designated beneficiary, to the executor or
administrator of the employee’s estate or (c) if no such executor or administrator has been appointed to the knowledge of the Company, to such other person(s) as the Company may, in its discretion, designate. If, prior to the last business
day of the Plan Period, the Designated Subsidiary by which an employee is employed shall cease to be a subsidiary of the Company, or if the employee is transferred to a subsidiary of the Company that is not a Designated Subsidiary, the employee
shall be deemed to have terminated employment for the purposes of this Plan. 
 13. Optionees Not Stockholders. Neither
the granting of an Option to an employee nor the deductions from his or her pay shall constitute such employee a stockholder of the shares of Common Stock covered by an Option under this Plan until such shares have been purchased by and issued
to him or her. 
 14. Rights Not Transferable. Rights under this Plan are not transferable by a participating employee
other than by will or the laws of descent and distribution, and are exercisable during the employee’s lifetime only by the employee. 
 15. Application of Funds. All funds received or held by the Company under this Plan may be combined with other corporate funds and may be used for any corporate purpose. 
 16. Adjustment 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 distribution to holders of Common Stock other than an ordinary cash dividend, (i) the number and class of securities available under this
Plan, (ii) the share limitations set forth in Section 10, and (iii) the Option Price shall be equitably adjusted by the Company in the manner determined by the Board or the Committee. 
  

 - 4 - 

 (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 exchange of all of the Common Stock of the Company
for cash, securities or other property pursuant to a share exchange transaction or (c) any liquidation or dissolution of the Company. 
 (2) Consequences of a Reorganization Event on Options. In connection with a Reorganization Event, the Board or the Committee shall take any one or more of the following actions as to outstanding
Options on such terms as the Board or the Committee determines: (i) provide that Options shall be assumed, or substantially equivalent Options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof),
(ii) upon written notice to employees, provide that all outstanding Options will be terminated as of the effective date of the Reorganization Event and that all such outstanding Options will become exercisable to the extent of accumulated
payroll deductions as of a date specified by the Board or the Committee in such notice, which date shall not be less than ten (10) days preceding the effective date of the Reorganization Event, (iii) upon written notice to employees,
provide that all outstanding Options will be cancelled as of a date prior to the effective date of the Reorganization Event and that all accumulated payroll deductions will be returned to participating employees on such date, (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 an employee equal to (A) the Acquisition Price times the number of shares of Common Stock subject to the employee’s Option (to the extent the Option Price does not exceed the Acquisition Price) minus (B) the aggregate
Option Price of such Option, in exchange for the termination of such Option, (v) provide that, in connection with a liquidation or dissolution of the Company, Options shall convert into the right to receive liquidation proceeds (net of the
Option Price thereof) and (vi) any combination of the foregoing. 
 For purposes of clause (i) above, an Option shall
be considered assumed if, following consummation of the Reorganization Event, the Option confers the right to purchase, for each share of Common Stock subject to the Option 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 of Options
to consist solely of common stock of the acquiring or succeeding corporation (or an affiliate thereof) equivalent in value (as determined by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a
result of the Reorganization Event.

 17. Amendment of the Plan. The Board may at any time, and from time to time, amend
this Plan in any respect, except that (a) if the approval of any such amendment by the shareholders of the Company is required by Section 423 of the Code, such amendment shall not be effected without such approval, and (b) in no event
may any amendment be made which would cause the Plan to fail to comply with Section 423 of the Code. 
 18. Insufficient
Shares. In the event that the total number of shares of Common Stock specified in elections to be purchased under any Offering plus the number of shares purchased under previous Offerings under this Plan exceeds the maximum number of shares
issuable under this Plan, the Board or the Committee will allot the shares then available on a pro-rata basis.

Termination of the Plan. This Plan may be terminated at any time by the Board. Upon termination of this Plan all amounts in the accounts of participating employees shall be promptly refunded. 
 20. Governmental Regulations. The Company’s obligation to sell and deliver Common Stock under this Plan is subject to
listing on a national stock exchange or quotation on the Nasdaq Global Market (to the extent the Common Stock is then so listed or quoted) and the approval of all governmental authorities required in connection with the authorization, issuance or
sale of such stock. 
 21. Governing Law. The Plan shall be governed by the laws of the State of Delaware, except to the
extent that such law is preempted by federal law. 
 22. Issuance of Shares. Shares may be issued upon exercise of an
Option from authorized but unissued Common Stock, from shares held in the treasury of the Company, or from any other proper source. 
 23. Notification upon Sale of Shares. Each employee agrees, by entering the Plan, to promptly give the Company notice of any disposition of shares purchased under the Plan where such disposition occurs within two years after the date
of grant of the Option pursuant to which such shares were purchased. 
 24. Grants to Employees in Foreign Jurisdictions.
The Company may, in order to comply with the laws of a foreign jurisdiction, grant Options to employees of the Company or a Designated Subsidiary who are citizens or residents of such foreign jurisdiction (without regard to whether they are also
citizens of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) with terms that are less favorable (but not more favorable) than the terms of Options granted under the Plan to employees of the Company
or a Designated Subsidiary who are resident in the United States. Notwithstanding the preceding provisions of this Plan, employees of the Company or a Designated Subsidiary who are citizens or residents of a foreign jurisdiction (without regard to
whether they are also citizens of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) may be excluded from eligibility under the Plan if (a) the grant of an Option under the Plan to a citizen or
resident of the foreign jurisdiction is prohibited under the laws of such jurisdiction or (b) compliance with the laws of the foreign jurisdiction would cause the Plan to violate the requirements of Section 423 of the Code. The Company may
add one or more appendices to this Plan describing the operation of the Plan in those foreign jurisdictions in which employees are excluded from participation or granted less favorable Options.

an employee.
