 Exhibit 10.1 

Indemnification Agreement 

This Indemnification Agreement (“Agreement”) is made as of
                 , 2018 by and between ARMO BioSciences, Inc., a Delaware corporation (the “Company”), and
                     (“Indemnitee”). This Agreement supersedes and replaces any and all previous Agreements between the Company and
Indemnitee covering the subject matter of this Agreement. 
 Recitals 

WHEREAS, the Board of Directors of the Company (the “Board”) believes that highly competent persons have become more
reluctant to serve publicly-held corporations as directors or officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them
arising out of their service to and activities on behalf of the corporation; 
 WHEREAS, the Board has determined that, in order to attract
and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of
such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the
future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating
to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Bylaws, as amended, of the Company (the “Bylaws”) and the Certificate of Incorporation, as
amended and/or restated, of the Company (the “Certificate of Incorporation”) require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General
Corporation Law of the State of Delaware (the “DGCL”). The Bylaws, Certificate of Incorporation and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that
contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification; 

WHEREAS, the uncertainties relating to such insurance and to indemnification may increase the difficulty of attracting and retaining such
persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the
best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself
to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws, Certificate of Incorporation and any resolutions adopted pursuant
thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and 
 [WHEREAS,
Indemnitee is a representative of or affiliated with                      (together with any affiliated venture capital funds and the general
partners, managing members or other control persons and/or any affiliated management companies, the “VC Funds,” and each, individually, a “VC Fund”), and has certain rights to indemnification and/or insurance provided by the VC
Funds, which Indemnitee and the VC Fund intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material condition to
Indemnitee’s willingness to serve on the Board.]1 
 WHEREAS, Indemnitee does not
regard the protection available under the Bylaws, Certificate of Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve or continue to serve as an officer or director without adequate protection, and
the Company desires Indemnitee to serve or continue to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified.

 NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and
agree as follows: 
 Section 1. Services to the Company. Indemnitee agrees to serve, as applicable, as a director, officer,
employee or agent of the Company or, at the request of the Company, as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other enterprise. Indemnitee may at any time and for any reason
resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in which event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement
shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s employment with the Company (or any of its subsidiaries or any
Enterprise), if any, is at will, and the Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any written employment contract between Indemnitee and the Company (or any of its
subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, 
  

	1 	 To be included in certain agreements of directors.

 
with respect to service as a director or officer of the Company, by the Certificate of Incorporation, the Company’s Bylaws, and the DGCL. The foregoing notwithstanding, this Agreement shall
continue in force after Indemnitee has ceased to serve, as applicable, as an officer, director, agent or employee of the Company or, at the request of the Company, as a director, officer, employee, agent or fiduciary of another corporation,
partnership, joint venture, trust or other enterprise, as provided in Section 16 hereof. 
 Section 2. Definitions. As used
in this Agreement: 
 (a) References to “agent” shall mean any person who is or was a director, officer, or employee of the
Company or a subsidiary of the Company or other person authorized by the Company to act for the Company, to include such person serving in such capacity as a director, officer, employee, fiduciary or other official of another corporation,
partnership, limited liability company, joint venture, trust or other enterprise at the request of, for the convenience of, or to represent the interests of the Company or a subsidiary of the Company. 

(b) A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any of the
following events: 
 i. Acquisition of Stock by Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined
below), directly or indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting power of the Company’s then outstanding securities unless the change in relative Beneficial Ownership of the
Company’s securities by any Person results solely from a reduction in the aggregate number of outstanding shares of securities entitled to vote generally in the election of directors; provided, however, that the foregoing shall not include any
Person having such status prior to the consummation of the initial public offering of the Company’s securities unless after the initial public offering such Person is or becomes the Beneficial Owner, directly or indirectly, of additional
securities of the Company representing in the aggregate an additional five percent (5%) or more of the combined voting power of the Company’s then outstanding securities; 

ii. Change in Board of Directors. During any period of two (2) consecutive years (not including any period prior to the execution of this
Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in Sections
2(b)(i), 2(b)(iii) or 2(b)(iv)) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who
either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute at least a majority of the members of the Board; 

 iii. Corporate Transactions. The effective date of a merger or consolidation of the Company with
any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) more than 51% of the combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation and with the power to elect at least a
majority of the board of directors or other governing body of such surviving entity; 
 iv. Liquidation. The approval by the stockholders of
the Company of a complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; and 

v. Other Events. There occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of
Regulation 14A (or a response to any similar item on any similar schedule or form) promulgated under the Exchange Act (as defined below), whether or not the Company is then subject to such reporting requirement. 

For purposes of this Section 2(b), the following terms shall have the following meanings: 

(A) “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended from time to time. 

(B) “Person” shall have the meaning as set forth in Sections 13(d) and 14(d) of the Exchange Act; provided,
however, that Person shall exclude (i) the Company, (ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company, and (iii) any corporation owned, directly or indirectly, by the stockholders of
the Company in substantially the same proportions as their ownership of stock of the Company. 
 (C) “Beneficial
Owner” shall have the meaning given to such term in Rule 13d-3 under the Exchange Act; provided, however, that Beneficial Owner shall exclude any Person otherwise becoming a Beneficial Owner by reason
of the stockholders of the Company approving a merger of the Company with another entity. 
 (c) “Corporate Status”
describes the status of a person who is or was a director, officer, employee or agent of the Company or of any other corporation, limited liability company, partnership or joint venture, trust or other enterprise which such person is or was serving
at the request of the Company. 

 (d) “Disinterested Director” shall mean a director of the Company who is not and
was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee. 
 (e) “Enterprise” shall
mean the Company and any other corporation, limited liability company, partnership, joint venture, trust or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, trustee, partner, managing
member, employee, agent or fiduciary. 
 (f) “Expenses” shall include all reasonable attorneys’ fees, retainers, court
costs, transcript costs, fees of experts and other professionals, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, any federal, state, local or foreign taxes imposed on
Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, ERISA excise taxes and penalties, and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending,
preparing to prosecute or defend, investigating, being or preparing to be a witness in, or otherwise participating in, a Proceeding. Expenses also shall include (i) Expenses incurred in connection with any appeal resulting from any Proceeding,
including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent, and (ii) for purposes of Section 14(d) only, Expenses incurred by Indemnitee in
connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement, by litigation or otherwise. The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written
demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable in the good faith judgment of such counsel shall be presumed conclusively
to be reasonable. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee. 

(g) “Independent Counsel” shall mean a law firm, or a member of a law firm, that is experienced in matters of corporation law
and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning the Indemnitee under this Agreement,
or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel”
shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under
this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to
this Agreement or its engagement pursuant hereto. 

 (h) The term “Proceeding” shall include any threatened, pending or completed
action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in the right of
the Company or otherwise and whether of a civil, criminal, administrative, legislative, or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party, potential party, non-party witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the Company, by reason of any action taken by Indemnitee (or a failure to take action by Indemnitee) or of any
action (or failure to act) on Indemnitee’s part while acting pursuant to Indemnitee’s Corporate Status, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification,
reimbursement, or advancement of Expenses can be provided under this Agreement. If the Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be considered a Proceeding under
this paragraph. 
 (i) Reference to “other enterprise” shall include employee benefit plans; references to
“fines” shall include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of
the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries, including as a deemed fiduciary thereto; and a person who acted in
good faith and in a manner Indemnitee reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in manner “not opposed to the best interests of the
Company” as referred to in this Agreement. 
 Section 3. Indemnity in Third-Party Proceedings. The Company shall
indemnify Indemnitee in accordance with the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a
judgment in its favor, by reason of Indemnitee’s Corporate Status. Pursuant to this Section 3, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in
settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on
Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company and, in
the case of a criminal Proceeding had no reasonable cause to believe that Indemnitee’s conduct was unlawful. The parties hereto intend that this Agreement shall provide to the fullest extent permitted by law for indemnification in excess of
that expressly permitted by statute, including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, vote of its stockholders or disinterested directors or applicable law. 

 Section 4. Indemnity in Proceedings by or in the Right of the Company. The Company
shall indemnify Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor, by
reason of Indemnitee’s Corporate Status. Pursuant to this Section 4, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on
Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. No
indemnification for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that the
Delaware Court (as hereinafter defined) or any court in which the Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and
reasonably entitled to indemnification. 
 Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provisions of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any
Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly
successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably
incurred by Indemnitee or on Indemnitee’s behalf in connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by law. For purposes of this Section 5 and without limitation, the
termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

Section 6. Indemnification For Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the fullest extent
permitted by applicable law and to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness or otherwise asked to participate in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified
against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

Section 7. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the
Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

 Section 8. Additional Indemnification. 

(a) Notwithstanding any limitation in Sections 3, 4, or 5, the Company shall indemnify Indemnitee to the fullest extent permitted by applicable
law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) by reason of Indemnitee’s Corporate Status. 

(b) For purposes of Section 8(a), the meaning of the phrase “to the fullest extent permitted by applicable law” shall
include, but not be limited to: 
 i. to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL, and 
 ii. to the
fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

Section 9. Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to
make any indemnification payment in connection with any claim involving Indemnitee: 
 (a) for which payment has actually been made to or on
behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 

(b) for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company
within the meaning of Section 16(b) of the Exchange Act (as defined in Section 2(b) hereof) or similar provisions of state statutory law or common law, (ii) any reimbursement of the Company by the Indemnitee of any bonus or other
incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting
restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in
violation of Section 306 of the Sarbanes-Oxley Act) or (iii) any reimbursement of the Company by Indemnitee of any compensation pursuant to any compensation recoupment or clawback policy adopted by the Board or the compensation committee
of the Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D of the Exchange Act; or 

 (c) except as provided in Section 14(d) of this Agreement, in connection with any Proceeding
(or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board
authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

Section 10. Advances of Expenses. Notwithstanding any provision of this Agreement to the contrary (other than Section 14(d)),
the Company shall advance, to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee or any Proceeding initiated by Indemnitee with the
prior approval of the Board as provided in Section 9(c), and such advancement shall be made within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to
or after final disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to
indemnification under the other provisions of this Agreement. In accordance with Section 14(d), advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred
preparing and forwarding statements to the Company to support the advances claimed. The Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that the
Indemnitee undertakes to repay the amounts advanced (without interest) to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. No other form of undertaking shall be required other than the
execution of this Agreement. This Section 10 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 9. 

Section 11. Procedure for Notification and Defense of Claim. 

(a) Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek indemnification or
advancement of Expenses hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. The written notification to the Company shall include a description of the nature of the Proceeding and the facts
underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is
reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding. The omission by Indemnitee to notify the Company hereunder will not relieve the Company from
any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company
shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 

 (b) The Company will be entitled to participate in the Proceeding at its own expense. 

Section 12. Procedure Upon Application for Indemnification. 

(a) Upon written request by Indemnitee for indemnification pursuant to Section 11(a), a determination, if required by applicable law, with
respect to Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or
(ii) if a Change in Control shall not have occurred, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of
the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which
shall be delivered to Indemnitee or (D) if so directed by the Board, by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days
after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable
advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including
attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to indemnification,
including a description of any reason or basis for which indemnification has been denied. 
 (b) In the event the determination of
entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) hereof, the Independent Counsel shall be selected as provided in this Section 12(b). If a Change in Control shall not have occurred, the
Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising Indemnitee of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent
Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the
identity of the Independent Counsel so selected. In either event, 

 
Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case
may be, a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel”
as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written
objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the Delaware Court has determined that such objection is without merit. If, within
twenty (20) days after the later of submission by Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition of the Proceeding, no Independent Counsel shall have been selected and not
objected to, either the Company or Indemnitee may petition the Delaware Court for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as
Independent Counsel of a person selected by such court or by such other person as such court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under
Section 12(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity
(subject to the applicable standards of professional conduct then prevailing). 
 Section 13. Presumptions and Effect of Certain
Proceedings. 
 (a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity
making such determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(a)
of this Agreement, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that
presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances
because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the
action or create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (b) Subject to Section 14(e), if the
person, persons or entity empowered or selected under Section 12 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of
the request therefor, the requisite determination of entitlement to indemnification 

 
shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) proof of a misstatement by Indemnitee of
a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law;
provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the determination with respect to
entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 13(b) shall
not apply (i) if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 12(a) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request
for such determination the Board has resolved to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made
thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so
called and such determination is made thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) of this Agreement. 

(c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good
faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was
unlawful. 
 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s
action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors or officers of the Enterprise in the course of their duties, or on the advice of legal
counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser, financial advisor or other expert selected with reasonable care by or on behalf of the
Enterprise. The provisions of this Section 13(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in this
Agreement. 
 (e) The knowledge and/or actions, or failure to act, of any director, officer, trustee, partner, managing member, fiduciary,
agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

 Section 14. Remedies of Indemnitee. 

(a) Subject to Section 14(e), in the event that (i) a determination is made pursuant to Section 12 of this Agreement that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 10 of this Agreement, (iii) no determination of entitlement to indemnification shall have been
made pursuant to Section 12(a) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5, 6 or 7 or the second to
last sentence of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Section 3, 4 or 8 of this Agreement is not made within
ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any other person takes or threatens to take any action to declare this Agreement void or
unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder, Indemnitee shall be entitled to an
adjudication by a court of Indemnitee’s entitlement to such indemnification or advancement of Expenses. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to
the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to
commence such proceeding pursuant to this Section 14(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce Indemnitee’s rights under Section 5 of
this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 
 (b) In the
event that a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be conducted
in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 14 the
Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 
 (c)
If a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to
this Section 14, absent (i) proof of a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of such indemnification under applicable law. 

 (d) The Company shall, to the fullest extent not prohibited by law, be precluded from asserting
in any judicial proceeding or arbitration commenced pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator
that the Company is bound by all the provisions of this Agreement. It is the intent of the Company that, to the fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation,
enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company
shall, to the fullest extent permitted by law, indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not
prohibited by law, such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’
and officers’ liability insurance policies maintained by the Company if, in the case of indemnification, Indemnitee is wholly successful on the underlying claims; if Indemnitee is not wholly successful on the underlying claims, then such
indemnification shall be only to the extent Indemnitee is successful on such underlying claims or otherwise as permitted by law, whichever is greater. 

(e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this
Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 Section 15. Non-exclusivity; Survival of Rights; Insurance; Subrogation. 
 (a) The rights of indemnification and
to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a
vote of stockholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or
omitted by Indemnitee in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of
Expenses than would be afforded currently under the Bylaws, Certificate of Incorporation and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No
right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

 (b) To the extent that the Company maintains an insurance policy or policies providing liability
insurance for directors, officers, employees, or agents of the Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer,
employee or agent under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such
claim or of the commencement of a Proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to
pay, on behalf of the Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. In the event of a Change in Control, or the Company becoming insolvent (including being placed into receivership or
entering the federal bankruptcy process and the like), the Company shall maintain in force any and all insurance policies then maintained by the Company in respect of Indemnitee (including directors’ and officers’ liability, fiduciary,
employment practices or otherwise), for a period of six years thereafter (“Tail Policy”). The Tail Policy shall be placed by the broker of the Company’s choice with incumbent insurance carriers using the policies that were in
place at the time of the Change in Control (unless the incumbent carriers do not offer such policies, in which case the Tail Policy shall be substantially comparable in scope and amount as the expiring policies, and the insurance carriers for the
Tail Policy shall have an AM Best rating that is the same or better than the AM Best ratings of the expiring policies). 
 (c) In the event
of any payment made by the Company under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such
rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 
 (d) The Company
shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable (or for which advancement is provided hereunder) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any
insurance policy, contract, agreement or otherwise. 
 (e) The Company’s obligation to indemnify or advance Expenses hereunder to
Indemnitee who is or was serving at the request of the Company as a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, limited liability company, partnership, joint venture, trust, employee
benefit plan or other enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such other corporation, limited liability company, partnership, joint venture, trust or other
enterprise. [The Company hereby acknowledges that 

 
Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by the Fund and certain of its affiliates (collectively, the “Fund Indemnitors”). The
Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or
liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of Expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in
settlement to the extent legally permitted and as required by the Certificate of Incorporation or Bylaws (or any agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and,
(iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees
that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of
contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of
the terms hereof.]2 
 Section 16. Duration of Agreement; Successors. 

(a) This Agreement shall continue until and terminate upon the later of: (i) ten (10) years after the date that Indemnitee shall have
ceased to serve as a director, officer, employee or agent of the Company or, at the request of the Company, as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other enterprise or
(ii) one (1) year after the final termination of any Proceeding then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to
Section 14 of this Agreement relating thereto. For the avoidance of doubt, this Agreement shall provide for rights of indemnification and advancement of Expenses as set forth herein for any event or occurrence related to Indemnitee’s
service for the Company, regardless of whether such events or occurrences occurred before or after the date of this Agreement. 
 (b) The
indemnification and advancement of expenses rights provided by or granted pursuant to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect
successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any
other Enterprise, and shall inure to the benefit of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators and 

 

	2 	 To be included in certain agreements of directors.

 
other legal representatives. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company, by written agreement, in form and substance reasonably satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be
required to perform if no such succession had taken place. 
 Section 17. Severability. If any provision or provisions of this
Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of
this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent
permitted by law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible,
the provisions of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be
construed so as to give effect to the intent manifested thereby. 
 Section 18. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order
to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving or continuing to serve as a director or officer of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation,
the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

Section 19. Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed
in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing waiver. 

Section 20. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with any summons,
citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company
shall not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise. 

 Section 21. Notices. All notices, requests, demands and other communications under
this Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) mailed by certified or
registered mail with postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been

 Section 22. Contribution. To the fullest extent permissible under

judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in
light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the

ARMO BIOSCIENCES, INC. 

2018 EQUITY INCENTIVE PLAN 

(AS ADOPTED ON JANUARY 5, 2018) 

 

 ARMO BIOSCIENCES, INC. 

2018 EQUITY INCENTIVE PLAN 

ARTICLE 1. INTRODUCTION. 
 The Board
adopted the Plan to become effective immediately, although no Awards may be granted prior to the IPO Date. The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by (a) encouraging
Service Providers to focus on critical long-range corporate objectives, (b) encouraging the attraction and retention of Service Providers with exceptional qualifications and (c) linking Service Providers directly to stockholder interests
through increased stock ownership. The Plan seeks to achieve this purpose by providing for Awards in the form of Options (which may be ISOs or NSOs), SARs, Restricted Shares and Restricted Stock Units. Capitalized terms used in this Plan are defined
in Article 14. 
 ARTICLE 2. ADMINISTRATION. 

2.1 General. The Plan may be administered by the Board or one or more Committees. Each Committee shall comply with rules and regulations
applicable to it, including under the rules of any exchange on which the Common Shares are traded, and shall have the authority and be responsible for such functions as have been assigned to it. 

2.2 Section 16. To the extent desirable to qualify transactions hereunder as exempt under Exchange Act Rule 16b-3, the transactions contemplated hereunder will be approved by the entire Board or a Committee of two or more “non-employee directors” within the meaning of
Exchange Act Rule 16b-3. 
 2.3 Powers of Administrator. Subject to the terms of the
Plan, and in the case of a Committee, subject to the specific duties delegated to the Committee, the Administrator shall have the authority to (a) select the Service Providers who are to receive Awards under the Plan, (b) determine the
type, number, vesting requirements and other features and conditions of such Awards, (c) interpret the Plan and Awards granted under the Plan, (d) make, amend and rescind rules relating to the Plan and Awards granted under the Plan,
including rules relating to sub-plans established for the purposes of satisfying applicable foreign laws or for qualifying for favorable tax treatment under applicable foreign laws, (e) impose such
restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by a Participant of any Common Shares issued pursuant to an Award, including restrictions under an insider trading policy and
restrictions as to the use of a specified brokerage firm for such resales, and (f) make all other decisions relating to the operation of the Plan and Awards granted under the Plan. In addition, with regard to the terms and conditions of Awards
granted to Service Providers outside of the United States, the Administrator may vary from the provisions of the Plan to the extent it determines it necessary and appropriate to do so. 

2.4 Effect of Administrator’s Decisions. The Administrator’s decisions, determinations and interpretations shall be
final and binding on all interested parties. 
 2.5 Governing Law. The Plan shall be governed by, and construed in accordance
with, the laws of the State of Delaware (except its choice-of-law provisions). 

 ARTICLE 3. SHARES AVAILABLE FOR GRANTS. 

3.1 Basic Limitation. Common Shares issued pursuant to the Plan may be authorized but unissued shares or treasury shares. The
aggregate number of Common Shares issued under the Plan shall not exceed the sum of (a) 3,175,864 Common Shares, (b) any Common Shares subject to outstanding options under the Predecessor Plan on the IPO Date that subsequently are
forfeited, expire or lapse unexercised and Common Shares issued pursuant to awards granted under the Predecessor Plan that are outstanding on the IPO Date and that are subsequently forfeited to or repurchased by the Company, and (c) the
additional Common Shares described in Articles 3.2 and 3.3; provided, however, that no more than 2,269,610 Common Shares shall be added to the Plan pursuant to clause (b). The number of Common Shares that are subject to Stock Awards
outstanding at any time under the Plan may not exceed the number of Common Shares that then remain available for issuance under the Plan. The numerical limitations in this Article 3.1 shall be subject to adjustment pursuant to Article 9.

 3.2 Annual Increase in Shares. On the first day of each fiscal year of
the Company during the term of the Plan, commencing on January 1, 2019 and ending on (and including) January 1, 2028, the aggregate number of Common Shares that may be issued under the Plan shall automatically increase by a number equal to
the lesser of (a) 4% of the total number of Common Shares actually issued and outstanding on the last day of the preceding fiscal year, (b) 1,905,518 of Common Shares (subject to adjustment pursuant to Section 9.1 below), or (c) a
number of Common Shares determined by the Board. Notwithstanding the foregoing, the Board retains the right in its sole discretion to forego an increase for any fiscal year following an annual review by the Board of the share reserve of the Plan.

 3.3 Shares Returned to Reserve. To the extent that Options, SARs or Restricted Stock Units are forfeited, cancelled or
expire for any reason before being exercised or settled in full, the Common Shares subject to such Options, SARs or Restricted Stock Units shall again become available for issuance under the Plan. If SARs are exercised or Restricted Stock Units are
settled, then only the number of Common Shares (if any) actually issued to the Participant upon exercise of such SARs or settlement of such Restricted Stock Units, as applicable, shall reduce the number of Common Shares available under
Article 3.1 and the balance shall again become available for issuance under the Plan. If Restricted Shares or Common Shares issued upon the exercise of Options are reacquired by the Company pursuant to a forfeiture provision, repurchase right
or for any other reason, then such Common Shares shall again become available for issuance under the Plan. Common Shares applied to pay the Exercise Price of Options or to satisfy tax withholding obligations related to any Award shall again become
available for issuance under the Plan. To the extent that an Award is settled in cash rather than Common Shares, the cash settlement shall not reduce the number of Shares available for issuance under the Plan. 

3.4 Awards Not Reducing Share Reserve. To the extent permitted under applicable stock exchange listing standards, any dividend
equivalents paid or credited under the Plan with respect to Restricted Stock Units shall not be applied against the number of Common Shares that may be issued under the Plan, whether or not such dividend equivalents are converted into Restricted
Stock Units. In addition, Common Shares subject to Substitute Awards granted by the Company shall not reduce the number of Common Shares that may be issued under Article 3.1, nor shall shares subject to Substitute Awards again be available for
Awards under the Plan in the event of any forfeiture, expiration or cash settlement of such Substitute Awards. 

  
 2 

 3.5 Code Section 422 and Other Limits. Subject to
adjustment in accordance with Article 9: 
 (a) The aggregate grant date fair value of Stock Awards granted to an Outside Director may not
exceed $500,000 in any one fiscal year of the Company. For purposes of this limitation, grant date fair value shall be determined in accordance with the assumptions that the Company uses to estimate the value of share-based payments for financial
reporting purposes. except that the grant date fair value of Stock Awards granted to a newly appointed Outside Director may not exceed $1,000,000 in the fiscal year of the Company in which such Outside Director is initially appointed to the Board.
This limitation shall not apply to Stock Awards or Common Shares granted pursuant to an Outside Director’s election to receive a Stock Award or Common Shares in lieu of cash retainers or other fees. In addition, Stock Awards granted to
an individual while he or she was an Employee or Consultant, but not an Outside Director, shall not count towards this limitation. 

(b) No more than 5,445,474 Common Shares may be issued under the Plan upon the exercise of ISOs. 

ARTICLE 4. ELIGIBILITY. 
 4.1
Incentive Stock Options. Only Employees who are common-law employees of the Company, a Parent or a Subsidiary shall be eligible for the grant of ISOs. In addition, an Employee who owns more than 10% of
the total combined voting power of all classes of outstanding stock of the Company or any of its Parents or Subsidiaries shall not be eligible for the grant of an ISO unless the additional requirements set forth in Code Section 422(c)(5) are
satisfied. 
 4.2 Other Awards. Awards other than ISOs may only be granted to Service Providers. 

ARTICLE 5. OPTIONS. 
 5.1 Stock
Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms of the Plan and may be subject to any other terms
that are not inconsistent with the Plan. The Stock Option Agreement shall specify whether the Option is intended to be an ISO or an NSO. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. 

5.2 Number of Shares. Each Stock Option Agreement shall specify the number of Common Shares subject to the Option, which number
shall adjust in accordance with Article 9. 
 5.3 Exercise Price. Each Stock Option Agreement shall specify the Exercise
Price, which shall not be less than 100% of the Fair Market Value of a Common Share on the date of grant. The preceding sentence shall not apply to an Option that is a Substitute Award granted in a manner that would satisfy the requirements of Code
Section 409A and, if applicable, Code Section 424(a). 

  
 3 

 5.4 Exercisability and Term. Each Stock Option Agreement shall specify the date or
event when all or any installment of the Option is to become vested and/or exercisable. The Stock Option Agreement shall also specify the term of the Option; provided that, except to the extent necessary to comply with applicable foreign law, the
term of an Option shall in no event exceed 10 years from the date of grant. A Stock Option Agreement may provide for accelerated vesting and/or exercisability upon certain specified events and may provide for expiration prior to the end of its
term in the event of the termination of the Optionee’s service. 
 5.5 Death of Optionee. After an Optionee’s death,
any vested and exercisable Options held by such Optionee may be exercised by his or her beneficiary or beneficiaries. Each Optionee may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company. A
beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Optionee’s death. If no beneficiary was designated or if no designated beneficiary survives the Optionee, then any vested and
exercisable Options held by the Optionee may be exercised by his or her estate. 
 5.6 Modification or Assumption of Options.
Within the limitations of the Plan, the Administrator may modify, reprice, extend or assume outstanding options or may accept the cancellation of outstanding options (whether granted by the Company or by another issuer) in return for the grant of
new Options for the same or a different number of shares and at the same or a different exercise price or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of an Option shall, without the consent of
the Optionee, impair his or her rights or obligations under such Option. 
 5.7 Buyout Provisions. The Administrator may at any
time (a) offer to buy out for a payment in cash or cash equivalents an Option previously granted or (b) authorize an Optionee to elect to cash out an Option previously granted, in either case at such time and based upon such terms and
conditions as the Administrator shall establish. 
 5.8 Payment for Option Shares. The entire Exercise Price of Common Shares
issued upon exercise of Options shall be payable in cash or cash equivalents at the time when such Common Shares are purchased. In addition, the Administrator may, in its sole discretion and to the extent permitted by applicable law, accept payment
of all or a portion of the Exercise Price through any one or a combination of the following forms or methods: 
 (a) Subject to any
conditions or limitations established by the Administrator, by surrendering, or attesting to the ownership of, Common Shares that are already owned by the Optionee with a value on the date of surrender equal to the aggregate exercise price of the
Common Shares as to which such Option will be exercised; 
 (b) By delivering (on a form prescribed by the Company) an irrevocable direction
to a securities broker approved by the Company to sell all or part of the Common Shares being purchased under the Plan and to deliver all or part of the sales proceeds to the Company; 

(c) Subject to such conditions and requirements as the Administrator may impose from time to time, through a net exercise procedure; or 

(d) Through any other form or method consistent with applicable laws, regulations and rules. 

  
 4 

 ARTICLE 6. STOCK APPRECIATION RIGHTS. 

6.1 SAR Agreement. Each grant of a SAR under the Plan shall be evidenced by a SAR Agreement between the Optionee and the Company.
Such SAR shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various SAR Agreements entered into under the Plan need not be identical. 

6.2 Number of Shares. Each SAR Agreement shall specify the number of Common Shares to which the SAR pertains, which number shall
adjust in accordance with Article 9. 
 6.3 Exercise Price. Each SAR Agreement shall specify the Exercise Price, which
shall in no event be less than 100% of the Fair Market Value of a Common Share on the date of grant. The preceding sentence shall not apply to a SAR that is a Substitute Award granted in a manner that would satisfy the requirements of Code
Section 409A. 
 6.4 Exercisability and Term. Each SAR Agreement shall specify the date when all or any installment of the
SAR is to become vested and exercisable. The SAR Agreement shall also specify the term of the SAR; provided that except to the extent necessary to comply with applicable foreign law, the term of a SAR shall not exceed 10 years from the date of
grant. A SAR Agreement may provide for accelerated vesting and exercisability upon certain specified events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s service. 

6.5 Exercise of SARs. Upon exercise of a SAR, the Optionee (or any person having the right to exercise the SAR after his or her
death) shall receive from the Company (a) Common Shares, (b) cash or (c) a combination of Common Shares and cash, as the Administrator shall determine. The amount of cash and/or the Fair Market Value of Common Shares received upon
exercise of SARs shall, in the aggregate, not exceed the amount by which the Fair Market Value (on the date of surrender) of the Common Shares subject to the SARs exceeds the Exercise Price. If, on the date when a SAR expires, the Exercise Price is
less than the Fair Market Value on such date but any portion of such SAR has not been exercised or surrendered, then such SAR shall automatically be deemed to be exercised as of such date with respect to such portion. A SAR Agreement may also
provide for an automatic exercise of the SAR on an earlier date. 
 6.6 Death of Optionee. After an Optionee’s death, any
vested and exercisable SARs held by such Optionee may be exercised by his or her beneficiary or beneficiaries. Each Optionee may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company. A beneficiary
designation may be changed by filing the prescribed form with the Company at any time before the Optionee’s death. If no beneficiary was designated or if no designated beneficiary survives the Optionee, then any vested and exercisable SARs held
by the Optionee at the time of his or her death may be exercised by his or her estate. 
 6.7 Modification or Assumption of
SARs. Within the limitations of the Plan, the Administrator may modify, reprice, extend or assume outstanding stock appreciation rights or may accept the cancellation of outstanding stock appreciation rights (whether granted by the Company or by
another issuer) in return for the grant of new SARs for the same or a different number of shares and at the same or a different exercise price or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of
a SAR shall, without the consent of the Optionee, impair his or her rights or obligations under such SAR.

 ARTICLE 7. RESTRICTED SHARES. 

7.1 Restricted Stock Agreement. Each grant of Restricted Shares under the Plan shall be evidenced by a Restricted Stock Agreement
between the recipient and the Company. Such Restricted Shares shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various Restricted Stock
Agreements entered into under the Plan need not be identical. 
 7.2 Payment for Awards. Restricted Shares may be sold or
awarded under the Plan for such consideration as the Administrator may determine, including (without limitation) cash, cash equivalents, property, cancellation of other equity awards, promissory notes, past services and future services, and such
other methods of payment as are permitted by applicable law. 
 7.3 Vesting Conditions. Each Award of Restricted Shares may or
may not be subject to vesting and/or other conditions as the Administrator may determine. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Stock Agreement. A Restricted Stock Agreement
may provide for accelerated vesting upon certain specified events. 
 7.4 Voting and Dividend Rights. The holders of Restricted
Shares awarded under the Plan shall have the same voting, dividend and other rights as the Company’s other stockholders, unless the Administrator otherwise provides. A Restricted Stock Agreement, however, may require that any cash dividends
paid on Restricted Shares (a) be accumulated and paid when such Restricted Shares vest, or (b) be invested in additional Restricted Shares. Such additional Restricted Shares shall be subject to the same conditions and restrictions as the
shares subject to the Stock Award with respect to which the dividends were paid. In addition, unless the Administrator provides otherwise, if any dividends or other distributions are paid in Common Shares, such Common Shares shall be subject to the
same restrictions on transferability and forfeitability as the Restricted Shares with respect to which they were paid. 
 7.5
Modification or Assumption of Restricted Shares. Within the limitations of the Plan, the Administrator may modify or assume outstanding Restricted Shares or may accept the cancellation of outstanding restricted shares (whether granted by the
Company or by another issuer) in return for the grant of new Restricted Shares for the same or a different number of shares or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of Restricted Shares
shall, without the consent of the Participant, impair his or her rights or obligations under such Restricted Shares. 
 ARTICLE 8. RESTRICTED STOCK
UNITS. 
 8.1 Restricted Stock Unit Agreement. Each grant of Restricted Stock Units under the Plan shall be
evidenced by a Restricted Stock Unit Agreement between the recipient and the Company. Such Restricted Stock Units shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The
provisions of the various Restricted Stock Unit Agreements entered into under the Plan need not be identical. 

  
 6 

 8.2 Payment for Awards. To the extent that an Award is granted in the form of
Restricted Stock Units, no cash consideration shall be required of the Award recipients. 
 8.3 Vesting Conditions. Each Award
of Restricted Stock Units may or may not be subject to vesting, as determined by the Administrator. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Stock Unit Agreement. A Restricted
Stock Unit Agreement may provide for accelerated vesting upon certain specified events. 
 8.4 Voting and Dividend Rights. The
holders of Restricted Stock Units shall have no voting rights. Prior to settlement or forfeiture, Restricted Stock Units awarded under the Plan may, at the Administrator’s discretion, provide for a right to dividend equivalents. Such right
entitles the holder to be credited with an amount equal to all cash dividends paid on one Common Share while the Restricted Stock Unit is outstanding. Dividend equivalents may be converted into additional Restricted Stock Units. Settlement of
dividend equivalents may be made in the form of cash, in the form of Common Shares, or in a combination of both. Prior to distribution, any dividend equivalents shall be subject to the same conditions and restrictions as the Restricted Stock Units
to which they attach. 
 8.5 Form and Time of Settlement of Restricted Stock Units. Settlement of vested
Restricted Stock Units may be made in the form of (a) cash, (b) Common Shares or (c) any combination of both, as determined by the Administrator. The actual number of Restricted Stock Units eligible for settlement may be larger or
smaller than the number included in the original Award, based on predetermined performance factors. Methods of converting Restricted Stock Units into cash may include (without limitation) a method based on the average value of Common Shares over a
series of trading days. Vested Restricted Stock Units shall be settled in such manner and at such time(s) as specified in the Restricted Stock Unit Agreement. Until an Award of Restricted Stock Units is settled, the number of such Restricted Stock
Units shall be subject to adjustment pursuant to Article 9. 
 8.6 Death of Recipient. Any Restricted Stock Units that
become payable after the recipient’s death shall be distributed to the recipient’s beneficiary or beneficiaries. Each recipient of Restricted Stock Units under the Plan may designate one or more beneficiaries for this purpose by filing the
prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Award recipient’s death. If no beneficiary was designated or if no designated beneficiary survives
the Award recipient, then any Restricted Stock Units that become payable after the recipient’s death shall be distributed to the recipient’s estate. 

8.7 Modification or Assumption of Restricted Stock Units. Within the limitations of the Plan, the Administrator may
modify or assume outstanding restricted stock units or may accept the cancellation of outstanding restricted stock units (whether granted by the Company or by another issuer) in return for the grant of new Restricted Stock Units for the same or a
different number of shares or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of a Restricted Stock Unit shall, without the consent of the Participant, impair his or her rights or obligations
under such Restricted Stock Unit. 
 8.8 Creditors’ Rights. A holder of Restricted Stock Units shall have no
rights other than those of a general creditor of the Company. Restricted Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of the applicable Restricted Stock Unit Agreement.

 ARTICLE 9. ADJUSTMENTS; DISSOLUTIONS AND LIQUIDATIONS; CORPORATE TRANSACTIONS. 

9.1 Adjustments. In the event of a subdivision of the outstanding Common Shares, a declaration of a dividend payable in Common
Shares, a combination or consolidation of the outstanding Common Shares (by reclassification or otherwise) into a lesser number of Common Shares or any other increase or decrease in the number of issued Common Shares effected without receipt of
consideration by the Company, proportionate adjustments shall be made to the following: 
 (a) The number and kind of shares available for
issuance under Article 3, including the numerical share limits in Articles 3.1 and 3.5; 
 (b) The number and kind of shares covered by
each outstanding Option, SAR and Restricted Stock Unit; and/or 
 (c) The Exercise Price applicable to each outstanding Option and SAR, and
the repurchase price, if any, applicable to Restricted Shares. 
 In the event of a declaration of an extraordinary dividend payable in a form other than
Common Shares in an amount that has a material effect on the price of Common Shares, a recapitalization, a spin-off or a similar occurrence, the Administrator may make such adjustments as it, in its sole
discretion, deems appropriate to the foregoing. Any adjustment in the number of shares subject to an Award under this Article 9.1 shall be rounded down to the nearest whole share, although the Administrator in its sole discretion may make a cash
payment in lieu of a fractional share. Except as provided in this Article 9, a Participant shall have no rights by reason of any issuance by the Company of stock of any class or securities convertible into stock of any class, any subdivision or
consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class. 

9.2 Dissolution or Liquidation. To the extent not previously exercised or settled, Options, SARs and Restricted Stock Units shall
terminate immediately prior to the dissolution or liquidation of the Company. 
 9.3 Corporate Transactions. In the event that
the Company is a party to a merger, consolidation, or a Change in Control (other than one described in Article 14.6(d)), all Common Shares acquired under the Plan and all Stock Awards outstanding on the effective date of the transaction shall be
treated in the manner described in the definitive transaction agreement (or, in the event the transaction does not entail a definitive agreement to which the Company is party, in the manner determined by the Administrator, with such determination
having final and binding effect on all parties), which agreement or determination need not treat all Stock Awards (or portions thereof) in an identical manner. Unless an Award Agreement provides otherwise, the treatment specified in the transaction
agreement or by the Administrator may include (without limitation) one or more of the following with respect to each outstanding Stock Award: 

(a) The continuation of such outstanding Stock Award by the Company (if the Company is the surviving entity); 

  
 8 

 (b) The assumption of such outstanding Stock Award by the surviving entity or its
parent, provided that the assumption of an Option or a SAR shall comply with applicable tax requirements; 
 (c) The
substitution by the surviving entity or its parent of an equivalent award for such outstanding Stock Award (including, but not limited to, an award to acquire the same consideration paid to the holders of Common Shares in the transaction), provided
that the substitution of an Option or a SAR shall comply with applicable tax requirements; 
 (d) In the case of an Option or
SAR, the cancellation of such Stock Award without payment of any consideration. An Optionee shall be able to exercise his or her outstanding Option or SAR, to the extent such Option or SAR is then vested or becomes vested as of the effective time of
the transaction, during a period of not less than five full business days preceding the closing date of the transaction, unless (i) a shorter period is required to permit a timely closing of the transaction and (ii) such shorter period
still offers the Optionee a reasonable opportunity to exercise such Option or SAR. Any exercise of such Option or SAR during such period may be contingent on the closing of the transaction; 

(e) The cancellation of such Stock Award and a payment to the Participant with respect to each share subject to the portion of
the Stock Award that is vested or becomes vested as of the effective time of the transaction equal to the excess of (A) the value, as determined by the Administrator in its absolute discretion, of the property (including cash) received by
the holder of a Common Share as a result of the transaction, over (if applicable) (B) the per-share Exercise Price of such Stock Award (such excess, if any, the “Spread”). Such payment shall be made in the form of cash,
cash equivalents, or securities of the surviving entity or its parent having a value equal to the Spread. In addition, any escrow, holdback, earn-out or similar provisions in the transaction agreement may
apply to such payment to the same extent and in the same manner as such provisions apply to the holders of Common Shares. If the Spread applicable to a Stock Award (whether or not vested) is zero or a negative number, then the Stock
Award may be cancelled without making a payment to the Participant. In the event that a Stock Award is subject to Code Section 409A, the payment described in this clause (e) shall be made on the settlement date specified in the applicable
Award Agreement, provided that settlement may be accelerated in accordance with Treasury Regulation Section 1.409A-3(j)(4); or 

(f) The assignment of any reacquisition or repurchase rights held by the Company in respect of an Award of Restricted Shares to
the surviving entity or its parent, with corresponding proportionate adjustments made to the price per share to be paid upon exercise of any such reacquisition or repurchase rights. 

Unless an Award Agreement provides otherwise, each outstanding Stock Award held by a Participant who remains a Service Provider as of the effective time of a
merger, consolidation or Change in Control (other than one described in Article 14.6(d)) (a “Current Participant”) shall become fully vested and, if applicable, exercisable immediately prior to the effective time of the transaction.
However the prior sentence shall not apply, and an outstanding Stock Award shall 

  
 9 

 
not become vested and, if applicable, exercisable, if and to the extent the Stock Award is continued, assumed or substituted as provided for in clauses (a), (b) or (c) above. In
addition, the prior two sentences will not apply to a Stock Award held by a Participant who is not a Current Participant, unless an Award Agreement provides otherwise or unless the Company and the acquirer agree otherwise. 

For avoidance of doubt, the Administrator shall have the discretion, exercisable either at the time a Stock Award is granted or at any time while the Stock
Award remains outstanding, to provide for the acceleration of vesting upon the occurrence of a Change in Control, whether or not the Stock Award is to be assumed or replaced in the transaction, or in connection with a termination of the
Participant’s service following a transaction. 
 Any action taken under this Article 9.3 shall either preserve a Stock Award’s status as exempt
from Code Section 409A or comply with Code Section 409A. 
 ARTICLE 10. OTHER AWARDS. 

Subject in all events to the limitations under Article 3 above as to the number of Common Shares available for issuance under this Plan, the
Company may grant other forms of equity-based awards not specifically described herein and may grant awards under other plans or programs, where such awards are settled in the form of Common Shares issued under this Plan. Such Common Shares shall be
treated for all purposes under the Plan like Common Shares issued in settlement of Restricted Stock Units and shall, when issued, reduce the number of Common Shares available under Article 3. 

ARTICLE 11. LIMITATION ON RIGHTS. 

11.1 Retention Rights. Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a right to
remain a Service Provider. The Company and its Parents, Subsidiaries and Affiliates reserve the right to terminate the service of any Service Provider at any time, with or without cause, subject to applicable laws, the Company’s certificate of
incorporation and by-laws and a written employment agreement (if any). 
 11.2
Stockholders’ Rights. Except as set forth in Article 7.4 or 8.4 above, a Participant shall have no dividend rights, voting rights or other rights as a stockholder with respect to any Common Shares covered by his or her
Award prior to the time when a stock certificate for such Common Shares is issued or, if applicable, the time when he or she becomes entitled to receive such Common Shares by filing any required notice of exercise and paying any required Exercise
Price. No adjustment shall be made for cash dividends or other rights for which the record date is prior to such time, except as expressly provided in the Plan. 

11.3 Regulatory Requirements. Any other provision of the Plan notwithstanding, the obligation of the Company to issue Common
Shares under the Plan shall be subject to all applicable laws, rules and regulations and such approval by any regulatory body as may be required. The Company reserves the right to restrict, in whole or in part, the delivery of Common Shares pursuant
to any Award prior to the satisfaction of all legal requirements relating to the issuance of such Common Shares, to their registration, qualification or listing or to an exemption from registration, qualification or listing. The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed necessary by the Company’s counsel to be necessary to the lawful issuance and sale of any Common Shares hereunder, will relieve the Company of
any liability in respect of the failure to issue or sell such Common Shares as to which such requisite authority will not have been obtained. 

  
 10 

 11.4 Transferability of Awards. The Administrator may, in its sole
discretion, permit transfer of an Award in a manner consistent with applicable law. Unless otherwise determined by the Administrator, Awards shall be transferable by a Participant only by (a) beneficiary designation, (b) a will or
(c) the laws of descent and distribution; provided that, in any event, an ISO may only be transferred by will or by the laws of descent and distribution and may be exercised during the lifetime of the Optionee only by the Optionee or by
the Optionee’s guardian or legal representative. 
 11.5 Other Conditions and Restrictions on Common Shares. Any Common
Shares issued under the Plan shall be subject to such forfeiture conditions, rights of repurchase, rights of first refusal, other transfer restrictions and such other terms and conditions as the Administrator may determine. Such conditions and
restrictions shall be set forth in the applicable Award Agreement and shall apply in addition to any restrictions that may apply to holders of Common Shares generally. In addition, Common Shares issued under the Plan shall be subject to such
conditions and restrictions imposed either by applicable law or by Company policy, as adopted from time to time, designed to ensure compliance with applicable law or laws with which the Company determines in its sole discretion to comply including
in order to maintain any statutory, regulatory or tax advantage. All Awards granted under the Plan, all amounts paid under the Plan and all Common Shares issued under the Plan shall be subject to recoupment in accordance with the Dodd-Frank Wall
Street Reform and Consumer Protection Act and any implementing regulations and/or listing standards thereunder, any compensation recovery policy adopted by the Company or as otherwise required by applicable law. 

ARTICLE 12. TAXES. 
 12.1
General. It is a condition to each Award under the Plan that a Participant or his or her successor shall make arrangements satisfactory to the Company for the satisfaction of any federal, state, local or foreign withholding tax obligations
that arise in connection with any Award granted under the Plan. The Company shall not be required to issue any Common Shares or make any cash payment under the Plan unless such obligations are satisfied. 

12.2 Share Withholding. To the extent that applicable law subjects a Participant to tax withholding obligations, the
Administrator may permit such Participant to satisfy all or part of such obligations by having the Company withhold all or a portion of any Common Shares that otherwise would be issued to him or her or by surrendering all or a portion of any Common
Shares that he or she previously acquired. Such Common Shares shall be valued on the date when they are withheld or surrendered. Any payment of taxes by assigning Common Shares to the Company may be subject to restrictions including any restrictions
required by SEC, accounting or other rules. 
 12.3 Section 409A Matters. Except as otherwise expressly set forth in an Award
Agreement, it is intended that Awards granted under the Plan either be exempt from, or comply with, the requirements of Code Section 409A. To the extent an Award is subject to Code Section 409A (a “409A Award”), the terms
of the Plan, the Award and any written agreement governing the Award shall be interpreted to comply with the requirements of Code Section 409A so that the Award is not subject to additional tax or interest under Code Section 409A, unless
the 

  
 11 

 
Administrator expressly provides otherwise. A 409A Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order for it to comply
with the requirements of Code Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” to an individual who is considered a “specified employee” (as each term is defined
under Code Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the Participant’s separation from service or (ii) the Participant’s death, but only to
the extent such delay is necessary to prevent such payment from being subject to Code Section 409A(a)(1). 
 12.4 Limitation
on Liability. Neither the Company nor any person serving as Administrator shall have any liability to a Participant in the event an Award held by the Participant fails to achieve its intended characterization under applicable tax law. 

ARTICLE 13. FUTURE OF THE PLAN. 

13.1 Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by the Board, subject to
approval of the Company’s stockholders under Article 13.3 below. The Plan shall terminate automatically 10 years after the date when the Board adopted the Plan. 

13.2 Amendment or Termination. The Board may, at any time and for any reason, amend or terminate the Plan. No Awards shall be
granted under the Plan after the termination thereof. The termination of the Plan, or any amendment thereof, shall not affect any Award previously granted under the Plan. 

13.3 Stockholder Approval. To the extent required by applicable law, the Plan will be subject to the approval of the
Company’s stockholders within 12 months of its adoption date. An amendment of the Plan shall be subject to the approval of the Company’s stockholders only to the extent required by applicable laws, regulations or rules.

STOCK OPTION AGREEMENT 

 

			
	Grant of Option	  	 Subject to all of the terms and conditions set forth in the Notice of Stock Option Grant (the “Grant Notice”), this Stock Option
Agreement (the “Agreement”) and the Plan, the Company has granted you an option to purchase up to the total number of shares specified in the Grant Notice at the exercise price indicated in the Grant Notice.

 
 All capitalized terms used in this Agreement shall have the meanings assigned to them
in this Agreement, the Grant Notice or the Plan.

		
	Tax Treatment	  	This option is intended to be a [nonstatutory] stock option, as provided in the Grant Notice.
		
	Vesting	  	 This option vests and becomes exercisable in accordance with the vesting schedule set forth in the Grant Notice.

 
 In no event will this option vest or become exercisable for additional shares after
your Service has terminated for any reason.

		
	Term of Option	  	This option expires in any event at the close of business at Company headquarters on the day before the 10th anniversary of the Date of Grant, as shown in the Grant Notice. (This option will expire earlier if your Service terminates
earlier, as described below, and this option may be terminated earlier as provided in Article 9 of the Plan.)
		
	Termination of Service	  	If your Service terminates for any reason, this option will expire to the extent it is unvested as of your termination date and does not vest as a result of your termination of Service. The Company determines when your Service
terminates for all purposes of this option.
		
	Regular Termination	  	If your Service terminates for any reason except death or total and permanent disability, then this option, to the extent vested as of your termination date, will expire at the close of business at Company headquarters on the date
three months after your termination date.
		
	Death	  	If you die before your Service terminates, then this option will expire at the close of business at Company headquarters on the date twelve months after the date of death.
		
	Disability	  	If your Service terminates because of your total and permanent disability, then this option will expire at the close of business at Company headquarters on the date six months after your termination
date.

			
		  	For all purposes under this Agreement, “total and permanent disability” means that you are unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which
can be expected to result in death or which has lasted, or can be expected to last, for a continuous period of not less than one year.
		
	Leaves of Absence and Part-Time Work	  	 For purposes of this option, your Service does not terminate when you go on a military leave, a sick leave or another bona fide leave
of absence, if the leave was approved by the Company in writing. However, your Service terminates when the approved leave ends, unless you immediately return to active work.
  

If you go on an unpaid leave of absence that lasts more than 30 days, then, to the extent permitted by applicable law, the vesting schedule specified in the
Grant Notice will be suspended on the thirty-first day of such unpaid leave, and this option will not vest or become exercisable with respect to any additional shares during the remainder of such leave. Vesting will resume when you return to active
Service. If you go on a paid leave of absence, the vesting schedule specified in the Notice of Stock Option Grant may be adjusted and/or suspended in accordance with the Company’s leave of absence policy or the terms of your leave.

 
 If you commence working on a part-time basis, the Company may adjust the vesting
schedule so that the rate of vesting is commensurate with your reduced work schedule.

		
	Restrictions on Exercise	  	The Company will not permit you to exercise this option if the issuance of shares at that time would violate any law or regulation.
		
	Notice of Exercise	  	 When you wish to exercise this option, you must notify the Company by filing the proper “Notice of Exercise” form at the address
given on the form or, if the Company has designated a third party to administer the Plan, you must notify such third party in the manner such third party requires. Your notice must specify how many shares you wish to purchase. The notice will be
effective when the Company receives it.
  
 However, if you wish to exercise this
option by executing a same-day sale (as described below), you must follow the instructions of the Company and the broker who will execute the sale.

 
 If someone else wants to exercise this option after your death, that person must prove
to the Company’s satisfaction that he or she is entitled to do so.
  
 You may
only exercise your option for whole shares.

	Form of Payment	  	 When you submit your notice of exercise, you must make arrangements for the payment of the option exercise price for the shares that you are
purchasing. To the extent permitted by applicable law, payment may be made in one (or a combination of two or more) of the following forms:
  

•    By delivering to the Company your personal check, a cashier’s check or a money
order, or arranging for a wire transfer.
  

•    By giving to a securities broker approved by the Company irrevocable directions to sell
all or part of your option shares and to deliver to the Company, from the sale proceeds, an amount sufficient to pay the option exercise price and any withholding taxes. (The balance of the sale proceeds, if any, will be delivered to you.) The
directions must be given in accordance with the instructions of the Company and the broker. This exercise method is sometimes called a “same-day sale.”

		
	Withholding Taxes	  	You will not be allowed to exercise this option unless you make arrangements acceptable to the Company and/or the Parent, Subsidiary or Affiliate employing you to pay any withholding taxes that may be due as a result of the option
exercise. These arrangements include payment in cash or via the same-day sale procedure described above. With the Company’s consent, these arrangements may also include (a) withholding shares of
Company stock that otherwise would be issued to you when you exercise this option with a value equal to withholding taxes, (b) surrendering shares that you previously acquired with a value equal to the withholding taxes, or (c) withholding
cash from other compensation. The value of withheld or surrendered shares, determined as of the date when taxes otherwise would have been withheld in cash, will be applied to the withholding taxes.
		
	Restrictions on Resale	  	You agree not to sell any option shares at a time when applicable laws, Company policies or an agreement between the Company and its underwriters prohibit a sale. This restriction will apply as long as your Service continues and for
such period of time after the termination of your Service as the Company may specify.
		
	Transfer of Option	  	 Prior to your death, only you may exercise this option. You cannot transfer or assign this option. For instance, you may not sell this option
or use it as security for a loan. If you attempt to do any of these things, this option will immediately become invalid. You may, however, dispose of this option in your will or by means of a written beneficiary designation which must be filed with
the Company on the proper form; provided, however, that your beneficiary or a representative of your estate acknowledges and agrees in writing in a form reasonably acceptable to the Company, to be bound by the provisions of this Agreement and the
Plan as if such beneficiary or representative of the estate were you.
  
 Regardless of
any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your former spouse, nor is the Company obligated to recognize your former spouse’s interest in your option in any other
way.

  
 3 

			
	No Retention Rights	  	Your option or this Agreement does not give you the right to be retained by the Company, a Parent, Subsidiary, or an Affiliate in any capacity. The Company and its Parents, Subsidiaries, and Affiliates reserve the right to terminate
your Service at any time, with or without cause.
		
	Stockholder Rights	  	You, or your estate or heirs, have no rights as a stockholder of the Company until you have exercised this option by giving the required notice to the Company, paying the exercise price, and satisfying any applicable withholding
taxes. No adjustments are made for dividends or other rights if the applicable record date occurs before you exercise this option, except as described in the Plan.
		
	Recoupment Policy	  	This option, and the shares acquired upon exercise of this option, shall be subject to any Company recoupment or clawback policy in effect from time to time.
		
	Adjustments	  	In the event of a stock split, a stock dividend or a similar change in Company stock, the number of shares covered by this option and the exercise price per share will be adjusted pursuant to the Plan.
		
	Effect of Significant Corporate Transactions	  	If the Company is a party to a merger, consolidation, or certain change in control transactions, then this option will be subject to the applicable provisions of Article 9 of the Plan.
		
	Applicable Law	  	This Agreement will be interpreted and enforced under the laws of the State of Delaware (without regard to its choice-of-law provisions).
		
	The Plan and Other Agreements	  	 The text of the Plan is incorporated in this Agreement by reference.

 
 This Plan, this Agreement and the Grant Notice constitute the entire understanding
between you and the Company regarding this option. Any prior agreements, commitments or negotiations concerning this option are superseded. This Agreement may be amended only by another written agreement between the parties.

Company’s Board of Directors; or (vii) your failure to cooperate in good faith with a governmental or internal investigation of the Company or its directors, officers or employees, if the Company has requested your cooperation.

or substantially all of the Company’s assets; (c) the consummation of a merger or consolidation of the Company with or into any other entity, other than a merger or consolidation which would result in the voting securities of the Company

Board of Directors was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall be considered as a member of the Incumbent Board.

 
 A transaction shall not constitute a Change in Control if its sole purpose is to change
the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction. 

 
 “Good Reason” means one of the following conditions has come into existence

notice.
