outstanding may request registration under the Securities Act of all or any portion of their Registrable Securities pursuant to a Registration Statement on Form S-1 or any successor form thereto (such
registration, a “Demand Registration”). The request for a Demand Registration shall specify the number of Registrable Securities requested to be included in the Demand Registration. Upon receipt of any such request, the
Company shall promptly (but in no event later than five Business Days following receipt thereof) deliver notice of such request to all other holders of Registrable Securities who shall then have 10 days from the date such notice is given to notify
the Company in writing of their desire to be included in such registration. The Company shall prepare and file with (or confidentially submit to) the Commission a Registration Statement on Form S-1 or any
successor form thereto covering all of the Registrable Securities that the holders thereof have requested to be included in such Demand Registration within 90 days after the date on which the initial request is given and shall use its commercially
reasonable efforts to cause such Registration Statement to be declared effective by the Commission as soon as practicable after the Lockup Expiration Date. The Company shall not be required to effect more than one Demand Registration for the holders
of Registrable Securities. 
 (b) At such time as the Company shall have qualified for the use of a Registration Statement on
Form S-3 or the then appropriate form for an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor rule thereto (a “Shelf Registration
Statement”), a holder of Registrable Securities shall have the right to request the registration under the Securities Act of all or any portion of their Registrable Securities for an offering on a delayed or continuous basis pursuant to
Rule 415 under the Securities Act or any successor rule thereto (a “Shelf Registration”). Such request for a Shelf Registration shall specify the number of Registrable Securities requested to be

  
 4 

 
included in the Shelf Registration. Upon receipt of any such request, the Company shall promptly (but in no event later than five Business Days following receipt thereof) deliver notice of such
request to all other holders of Registrable Securities, if any, who shall then have 10 days from the date such notice is given to notify the Company in writing of their desire to be included in such registration. The Company shall prepare and file
with or confidentially submit to the Commission a Shelf Registration Statement covering all of the Registrable Securities that the holders thereof have requested to be included in such Shelf Registration within 45 days after the date on which the
initial request is given and shall use commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission as soon as practicable thereafter. Each Shelf Registration Statement shall provide for the
resale pursuant to any method or combination of methods legally available to, and requested by, the holders of Registrable Securities. After the filing of a Shelf Registration Statement, and until all Registrable Securities covered by such Shelf
Registration Statement have ceased to be Registrable Securities, the Company shall use its commercially reasonable efforts to ensure that such Shelf Registration Statement remains continuously effective. 

(c) At any time that the Shelf Registration Statement is effective, if a holder of Registrable Securities covered by such Shelf
Registration Statement delivers a notice to the Company (a “Shelf Takedown Notice”) stating that such holder intends to effect an offering of all or part of its Registrable Securities included in such Shelf Registration Statement (a
“Shelf Takedown”) and the Company is eligible to use such Shelf Registration Statement for such Shelf Takedown, then the Company shall take all actions reasonably required, including amending or supplementing such Shelf Registration
Statement, to enable such Registrable Securities to be offered and sold as contemplated by such Shelf Takedown Notice. Each Shelf Takedown Notice shall specify the number of Registrable Securities to be offered and sold under the Shelf Takedown.
Upon receipt of a Shelf Takedown Notice, the Company shall promptly (but in no event later than 2 Business Days following receipt thereof) deliver notice of such Shelf Takedown Notice to all other holders of Registrable Securities, if any, who shall
then have 5 Business Days from the date such notice is given to notify the Company in writing of their desire to be included in such Shelf Takedown. The Company shall prepare and file with the Commission a Shelf Supplement as soon as practicable
after the date on which it received the Shelf Takedown Notice and, if such Shelf Supplement is an amendment to such Shelf Registration Statement, shall use its commercially reasonable efforts to cause such Shelf Supplement to be declared effective
by the Commission as soon as practicable thereafter. The priority for inclusion of Registrable Securities in a Shelf Takedown will be determined as specified in Section 2(f). 

(d) The Company shall not be obligated to effect any Shelf Takedown within 120 days after the effective date of a previous
Shelf Takedown in which holders of Registrable Securities were permitted to register the offer and sale under the Securities Act, and actually sold, at least 50% of the Registrable Securities requested to be included therein. Additionally, the
Company shall not be obligated to effect any Shelf Takedown with respect to any offering that would reasonably be expected to result in net proceeds of less than $30 million to the participating holders. The Company may postpone for up to 120
days the filing or effectiveness of a Registration Statement for any Shelf Takedown and the filing of any Shelf Supplement if the Board determines in its reasonable good faith judgment that such Shelf

  
 5 

 
Takedown would: (i) materially interfere with a significant acquisition, corporate organization, financing, securities offering or other similar transaction involving the Company;
(ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to materially comply with requirements under the Securities Act
or Exchange Act; provided, that in such event the holders of a majority of the Registrable Securities initiating such Shelf Takedown shall be entitled to withdraw such request and, if such request for a Shelf Takedown is withdrawn, such Shelf
Takedown shall not count as one of the permitted Shelf Takedowns hereunder and the Company shall pay all registration expenses in connection with such registration. The Company may delay a Shelf Takedown hereunder only twice in any period of 12
consecutive months. 
 (e) If the holders of Registrable Securities initially requesting a Demand Registration or Shelf
Takedown elect to distribute the Registrable Securities covered by their request in an underwritten offering, they shall so advise the Company as a part of their request made pursuant to Section 2(a) or
Section 2(b) and the Company shall include such information in its notice to the other holders of Registrable Securities. The Company, on the one hand, and the holders of the Registrable Securities (pursuant to the consent
of the holders of a majority of the Registrable Securities proposed to be included in such Demand Registration or Shelf Takedown), on the other, shall each select an investment banking firm to act as one of the two managing underwriters in
connection with such offering; provided, that such selection shall be subject to the consent of the other Party, which consent shall not be unreasonably withheld or delayed. 

(f) The Company may include in any Demand Registration or Shelf Takedown for an underwritten offering any securities that are
not Registrable Securities on behalf of the Company or on behalf of a holder of Common Stock that are not Registrable Securities if such holder has contractual piggyback registration rights and such securities are registered on a Shelf Registration
Statement; provided, however, that if a Shelf Takedown involves an underwritten offering and the managing underwriter of the requested Demand Registration or Shelf Takedown advises the Company and the holders of Registrable Securities
in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in the Demand Registration or Shelf Takedown, including all Registrable Securities and all other shares of Common Stock proposed to
be included in such underwritten offering, exceeds the number of shares of Common Stock that can be sold in such underwritten offering and/or the number of shares of Common Stock proposed to be included in such Demand Registration or Shelf Takedown
would adversely affect the price per share of the Common Stock proposed to be sold in such underwritten offering, the Company shall include in such Demand Registration or Shelf Takedown (i) first, the shares of Common Stock that the holders of
Registrable Securities propose to sell, and (ii) second, the shares of Common Stock proposed to be included therein by any other Persons (including shares of Common Stock to be sold for the account of the Company and/or other holders of Common
Stock) allocated among such Persons in such manner as they may agree. If the managing underwriter determines that less than all of the Registrable Securities proposed to be sold can be included in such offering, then the Registrable Securities that
are included in such offering shall be allocated pro rata among the respective holders thereof on the basis of the number of shares of Common Stock owned by each such holder or in such manner as they may agree.

 3. Piggyback Sale. 

(a) Whenever the Company proposes the offer and sale of any of the Company’s Common Stock or other securities under the
Securities Act (other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to employees or directors of the Company
pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under
the Securities Act or any successor rule thereto), or (iii) in connection with any dividend or distribution reinvestment or similar plan), whether for its own account or for the account of one or more stockholders of the Company (a
“Piggyback Sale”), the Company shall give prompt written notice (in any event no later than 10 days prior to the initiation of such offer and sale) to the holders of Registrable Securities of its intention to effect such an offer
and sale and, subject to Sections 3(b) and 3(c), shall include in such an offer and sale all Registrable Securities with respect to which the Company has received written requests for inclusion from the holders of
Registrable Securities within 7 Business Days after the Company’s notice has been given to each such holder. The Company may postpone or withdraw such offering or sale at any time in its sole discretion. 

(b) If a Piggyback Sale is initiated as a primary underwritten offering on behalf of the Company and the managing underwriter
advises the Company and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include Registrable Securities in such Piggyback Sale) in writing that in its reasonable and good faith opinion the number of
shares of Common Stock proposed to be included in such registration or takedown, including all Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common
Stock that can be sold in such offering and/or that the number of shares of Common Stock proposed to be included in any such registration or takedown would adversely affect the price per share of the shares of Common Stock to be sold in such
offering, the Company shall include in such registration or takedown (i) first, the shares of Common Stock that the Company proposes to sell; and (ii) second, the shares of Common Stock requested to be included therein by holders of
Registrable Securities, allocated among such holders pro rata based on the number of shares of Common Stock held by each applicable holder or in such manner as they may agree. 

(c) If a Piggyback Sale is initiated as an underwritten offering on behalf of a holder of shares of Common Stock other than
Registrable Securities, and the managing underwriter advises the Company in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in such registration or takedown, including all
Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common Stock that can be sold in such offering and/or that the number of shares of Common Stock
proposed to be included in any such registration or takedown would adversely affect the price per share of the Common Stock to be sold in such offering, the Company shall include in such registration or takedown (i) first, the shares of Common
Stock requested to be included therein by the holder(s) requesting such registration or takedown; and (ii) second, the shares of Common Stock requested to be included therein by the holders of Registrable Securities and by the other holders of
shares of Common Stock (other than holders of Registrable Securities) with registration rights entitling them to participate in such underwritten offering, allocated among such holders pro rata on the basis of the number of shares of Common Stock
held by each applicable holder or in such manner as they may agree. 

  
 7 

 (d) If any Piggyback Sale is initiated as a primary underwritten offering on
behalf of the Company, the Company shall select the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering. 

4. Lock-up Agreement. Each holder of Registrable Securities agrees that in connection with any
registered offering of Common Stock or other equity securities of the Company, and upon the request of the managing underwriter in such offering, if, after giving effect to the disposition of Common Stock in such offering such holder of such
Registrable Securities would continue to own at least 10% of the total number of outstanding shares of Common Stock, such holder shall not, without the prior written consent of such managing underwriter, during the period commencing 10 days prior to
the effective date of such registration and ending on the date specified by such managing underwriter (such period not to exceed 180 days without the prior written consent of a majority of the holders of Registrable Securities to be included in such
offering), (a) offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, hedge the beneficial ownership of or otherwise dispose of, directly or indirectly, any Common Stock or any
securities convertible into, exercisable for or exchangeable for Common Stock (whether such shares or any such securities are then owned by such holder or are thereafter acquired), or (b) enter into any swap or other arrangement that transfers
to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise. The foregoing provisions of this Section 4 shall not apply to sales of Registrable Securities to be included in such offering pursuant to Section 2 or
Section 3(a). Each holder of Registrable Securities agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the managing underwriter that are consistent with the foregoing or
that are necessary to give further effect thereto. Notwithstanding anything to the contrary contained in this Section 4, each holder of Registrable Securities shall be released, pro rata, from any lock-up agreement entered into pursuant to this Section 4 in the event and to the extent that the managing underwriter or the Company permit any discretionary waiver or termination of the
restrictions of any lock-up agreement pertaining to any officer, director or holders participating in the applicable offering. 

5. Registration Procedures. If and whenever the holders of Registrable Securities request that the offer and sale of any Registrable
Securities be registered under the Securities Act or any Registrable Securities be distributed in a Shelf Takedown pursuant to the provisions of this Agreement, the Company shall use its commercially reasonable efforts to effect the offer and sale
of such Registrable Securities under the Securities Act in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as soon as reasonably practicable and as applicable:

Securities, such holder’s officers, directors, managers, members, partners, stockholders, employees and Affiliates, each underwriter, broker or any other Person acting on behalf of such holder of Registrable Securities and each other
Controlling Person, if any, who controls any of the foregoing Persons, against all losses, claims, actions, damages, liabilities and expenses, joint or several, to which any of the foregoing Persons may become subject under the Securities Act or
otherwise, insofar as such losses, claims, actions, damages, liabilities or expenses arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus, preliminary
Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule thereto) or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus, in light of the circumstances under which they were made) not misleading; and shall reimburse such Persons for any legal or
other expenses reasonably incurred by any of them in connection with investigating or defending any such loss, claim, action, damage or liability, except insofar as the same are caused by or contained in any information furnished in writing to the
Company by such holder expressly for use therein or by such holder’s failure to deliver a copy of the Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any
successor rule thereto) or any amendments or supplements thereto (if the same was required by applicable law to be so delivered) after the Company has furnished such holder with a sufficient number of copies of the same prior to any written
confirmation of the sale of Registrable Securities. This indemnity shall be in addition to any liability the Company may otherwise have. 

  
 12 

 (b) In connection with any registration in which a holder of Registrable
Securities is participating, such holder shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall
indemnify and hold harmless, the Company, each director of the Company, each officer of the Company who shall sign such Registration Statement, each underwriter, broker or other Person acting on behalf of the holders of Registrable Securities and
each Controlling Person who controls any of the foregoing Persons against any losses, claims, actions, damages, liabilities or expenses resulting from any untrue or alleged untrue statement of material fact contained in the Registration Statement,
Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule thereto) or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus, in light of the circumstances under which they were made) not misleading, but only to the
extent that such untrue statement or omission is contained in any information so furnished in writing by such holder; provided, that the obligation to indemnify shall be several, not joint and several, for such holder and shall not exceed an
amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such holder from the sale of Registrable Securities pursuant to such Registration Statement. This indemnity shall be in addition to any
liability the selling holder may otherwise have. 
 (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action involving a claim referred to in this Section 7, such indemnified party shall, if a claim in respect thereof is made against an indemnifying party, give written notice to the latter of the
commencement of such action. The failure of any indemnified party to notify an indemnifying party of any such action shall not (unless such failure shall have a material adverse effect on the indemnifying party) relieve the indemnifying party from
any liability in respect of such action that it may have to such indemnified party hereunder. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense of
the claims in any such action that are subject or potentially subject to indemnification hereunder, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified
party, and after written notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof; provided, that, if (i) any indemnified party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such indemnified party which
are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity provided hereunder, or (ii) such action seeks an
injunction or equitable relief against any indemnified party or involves actual or alleged criminal activity, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party without such
indemnified party’s prior written consent (but, without such consent, shall have the right to participate therein with counsel of its choice) and such indemnifying party shall reimburse such indemnified party and any Controlling Person of such
indemnified party for that portion of the fees and expenses of any 

  
 13 

 
counsel retained by the indemnified party which is reasonably related to the matters covered by the indemnity provided hereunder. If the indemnifying party is not entitled to, or elects not to,
assume the defense of a claim, it shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified
party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicting indemnified parties shall have a right to retain one separate counsel
chosen by the holders of a majority of the Registrable Securities included in the registration, at the expense of the indemnifying party. 

(d) If the indemnification provided for hereunder is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such
indemnified party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection
with the statements or omissions that resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided, that the maximum amount of liability in respect of such contribution shall be
limited, in the case of each holder of Registrable Securities, to an amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such seller from the sale of Registrable Securities effected pursuant to
such registration. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, whether the violation of the Securities Act or any other similar federal or state securities laws or rule or regulation
promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any applicable registration, qualification or compliance was perpetrated by the indemnifying party or the indemnified
party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Parties agree that it would not be just and equitable if contribution pursuant hereto were determined
by pro rata allocation or by any other method or allocation which does not take account of the equitable considerations referred to herein. No Person guilty or liable of fraudulent misrepresentation within the meaning of Section 11(f) of the
Securities Act shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 
 8.
Participation in Underwritten Registrations. No Person may participate in any registration hereunder that is underwritten unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting
arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required
under the terms of such underwriting arrangements. 

  
 14 

 9. Rule 144 Compliance. With a view to making available to the holders of Registrable
Securities the benefits of Rule 144 and any other rule or regulation of the Commission that may at any time permit a holder to sell securities of the Company to the public without registration, after the Registration Date, the Company shall: 

(a) use commercially reasonable efforts to make and keep public information available, as those terms are understood and
defined in Rule 144, at all times after the Registration Date;

Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act, at any time after the Registration Date; and 

(c) furnish to any holder so long as such holder owns Registrable Securities, promptly upon request, (i) a written
statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company, (iii) such other reports
and documents so filed or furnished by the Company as such holder may reasonably request in connection with the sale of Registrable Securities without registration and (iv) the opinion of the Company’s outside counsel, in form and
substance reasonably acceptable to the transfer agent for the Common Stock, relating to such matters as such transfer agent may reasonably request in connection with the removal of any restrictive legends contained on such Common Stock. 

10. Recapitalization, Exchanges, Etc. Affecting the Securities. The provisions of this Agreement shall apply to the full extent set
forth herein with respect to any and all Common Stock of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in substitution of,
the Registrable Securities, and shall be appropriately adjusted for combinations, splits, recapitalizations, pro rata distributions and the like occurring on or after the date of this Agreement. 

11. Termination. This Agreement shall terminate and be of no further force or effect when there shall no longer be any Registrable
Securities outstanding; provided, that the provisions of Section 6 and Section 7 shall survive any such termination. 

12. Notices. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to
have been duly given or made as follows: (a) if sent by registered or certified mail in the United States return receipt requested, upon receipt; (b) if sent by nationally recognized overnight air courier, one (1) Business Day after

(v) modify, waive or adjust any term or condition of an Award that has been granted, which may include the acceleration of vesting, waiver of
forfeiture restrictions, modification of the form of settlement of the Award (for example, from cash to Stock or vice versa), early termination of a performance period, or modification of any other condition or limitation regarding an Award; 

(vi) determine the treatment of an Award upon a termination of employment or other service relationship; 

(vii) impose a holding period with respect to an Award or the shares of Stock received in connection with an Award; 

(viii) interpret and administer the Plan and any Award Agreement; 

(ix) correct any defect, supply any omission or reconcile any inconsistency in the Plan, in any Award, or in any Award Agreement; and 

(x) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan.

 The express grant of any specific power to the Committee, and the taking of any action by the Committee, shall not be construed as
limiting any power or authority of the Committee. Any action of the Committee shall be final, conclusive and binding on all persons, including the Company, its Affiliates, stockholders, Participants, beneficiaries, and permitted transferees under
Section 7(a) or other persons claiming rights from or through a Participant.

 (b) Exercise of Committee Authority. At any time that a member of the Committee is not a
Qualified Member, any action of the Committee relating to an Award granted or to be granted to an Eligible Person who is then subject to Section 16 of the Exchange Act in respect of the Company where such action is not taken by the full Board,
may be taken either (A) by a subcommittee, designated by the Committee, composed solely of two or more Qualified Members, or (B) by the Committee but with each such member who is not a Qualified Member abstaining or recusing himself or
herself from such action; provided, however, that upon such abstention or recusal, the Committee remains composed solely of two or more Qualified Members. Such action, authorized by such a subcommittee or by the Committee upon the
abstention or recusal of such non-Qualified Member(s), shall be the action of the Committee for purposes of the Plan. For the avoidance of doubt, the full Board may take any action relating to an Award granted
or to be granted to an Eligible Person who is then subject to Section 16 of the Exchange Act in respect of the Company. 
 (c)
Delegation of Authority. The Committee may delegate any or all of its powers and duties under the Plan to a subcommittee of directors or to any officer of the Company, including the power to perform administrative functions and grant Awards;
provided, however, that such delegation does not (i) violate state or corporate law or (ii) result in the loss of an exemption under Rule 16b-3(d)(1) for Awards granted to Participants
subject to Section 16 of the Exchange Act in respect of the Company. Upon any such delegation, all references in the Plan to the “Committee,” other than in Section 8, shall be deemed to include any
subcommittee or officer of the Company to whom such powers have been delegated by the Committee. Any such delegation shall not limit the right of such subcommittee members or such an officer to receive Awards; provided, however, that
such subcommittee members and any such officer may not grant Awards to himself or herself, a member of the Board, or any executive officer of the Company or an Affiliate, or take any action with respect to any Award previously granted to himself or
herself, a member of the Board, or any executive officer of the Company or an Affiliate. The Committee may also appoint agents who are not executive officers of the Company or members of the Board to assist in administering the Plan,
provided, however, that such individuals may not be delegated the authority to grant or modify any Awards that will, or may, be settled in Stock. 

(d) Limitation of Liability. The Committee and each member thereof shall be entitled to, in good faith, rely or act upon any report or
other information furnished to him or her by any officer or employee of the Company or any of its Affiliates, the Company’s legal counsel, independent auditors, consultants or any other agents assisting in the administration of the Plan.
Members of the Committee and any officer or employee of the Company or any of its Affiliates acting at the direction or on behalf of the Committee shall not be personally liable for any action or determination taken or made in good faith with
respect to the Plan, and shall, to the fullest extent permitted by law, be indemnified and held harmless by the Company with respect to any such action or determination. 

(e) Participants in Non-U.S. Jurisdictions. Notwithstanding any provision of the Plan to the
contrary, to comply with applicable laws in countries other than the United States in which the Company or any of its Affiliates operates or has employees, directors or other service providers from time to time, or to ensure that the Company
complies with any applicable requirements of foreign securities exchanges, the Committee, in its sole discretion, shall have the 

  
 6 

 
power and authority to: (i) determine which of the Company’s Affiliates shall be covered by the Plan; (ii) determine which Eligible Persons outside the United States are eligible
to participate in the Plan; (iii) modify the terms and conditions of any Award granted to Eligible Persons outside the United States to comply with applicable foreign laws or listing requirements of any foreign exchange; (iv) establish sub-plans and modify exercise procedures and other terms and procedures, to the extent such actions may be necessary or advisable (any such sub-plans and/or modifications
shall be attached to the Plan as appendices), provided, however, that no such sub-plans and/or modifications shall increase the share limitations contained in
Section 4(a); and (v) take any action, before or after an Award is granted, that it deems advisable to comply with any applicable governmental regulatory exemptions or approval or listing requirements of any such
foreign securities exchange. For purposes of the Plan, all references to foreign laws, rules, regulations or taxes shall be references to the laws, rules, regulations and taxes of any applicable jurisdiction other than the United States or a
political subdivision thereof. 
 4. Stock Subject to Plan. 

(a) Number of Shares Available for Delivery. Subject to adjustment in a manner consistent with Section 8,
3,300,000 shares of Stock are reserved and available for delivery with respect to Awards, and such total shall be available for the issuance of shares upon the exercise of ISOs. 

(b) Application of Limitation to Grants of Awards. Subject to Section 4(c), no Award may be granted if the
number of shares of Stock that may be delivered in connection with such Award exceeds the number of shares of Stock remaining available under the Plan minus the number of shares of Stock issuable in settlement of or relating to then-outstanding
Awards. The Committee may adopt reasonable counting procedures to ensure appropriate counting, avoid double counting (as, for example, in the case of tandem or Substitute Awards) and make adjustments if the number of shares of Stock actually
delivered differs from the number of shares previously counted in connection with an Award. 
 (c) Availability of Shares Not Delivered
under Awards. If all or any portion of an Award expires or is cancelled, forfeited, exchanged, settled in cash or otherwise terminated, the shares of Stock subject to such Award (including (i) shares forfeited with respect to Restricted
Stock, and (ii) the number of shares withheld or surrendered to the Company in payment of any exercise or purchase price of an Award or taxes relating to Awards) shall not be considered “delivered shares” under the Plan, shall be
available for delivery with respect to Awards, and shall no longer be considered issuable or related to outstanding Awards for purposes of Section 4(b). If an Award may be settled only in cash, such Award need not be
counted against any share limit under this Section 4. 
 (d) Shares Available Following Certain
Transactions. Substitute Awards shall not reduce the shares authorized for issuance under the Plan or the limitations on grants to non-employee members of the Board under
Section 5(b), nor shall shares subject to a Substitute Award be added to the shares available for issuance under the Plan as provided above. Additionally, in the event that a company acquired by the Company or any
subsidiary or with which the Company or any subsidiary combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination,

  
 7 

 
the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other
adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may, if and to the extent determined by
the Board, be used for Awards under the Plan and shall not reduce the shares authorized for issuance under the Plan (and shares subject to such Awards shall not be added to the shares available for issuance under the Plan as provided above);
provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and
shall only be made to individuals who were not, prior to such acquisition or combination, employed by (and who were not non-employee directors or consultants of) the Company or any of its subsidiaries
immediately prior to such acquisition or combination. 
 (e) Stock Offered. The shares of Stock to be delivered under the Plan shall
be made available from (i) authorized but unissued shares of Stock, (ii) Stock held in the treasury of the Company, or (iii) previously issued shares of Stock reacquired by the Company, including shares purchased on the open market.

 5. Eligibility; Per Person Award Limitations. 

(a) Awards may be granted under the Plan only to Eligible Persons. 

(b) In each calendar year during any part of which the Plan is in effect, a non-employee member of the
Board may not be granted Awards having a value (determined, if applicable, pursuant to ASC Topic 718) on the date of grant in excess of $750,000 multiplied by the number of full or partial calendar years in any performance period established with
respect to an Award, if applicable; provided, that, for the calendar year in which a non-employee member of the Board first commences service on the Board only, the foregoing limitations shall be doubled;
provided, further that, the limits set forth in this Section 5(b) shall be without regard to grants of Awards, if any, made to a non-employee member of the Board during any period in
which such individual was an employee of the Company or of any of its Affiliates or was otherwise providing services to the Company or to any of its Affiliates other than in the capacity as a director of the Company. 

6. Specific Terms of Awards. 

(a) General. Awards may be granted on the terms and conditions set forth in this Section 6. Awards granted
under the Plan may, in the discretion of the Committee, be granted either alone, in addition to, or in tandem with any other Award. In addition, the Committee may impose on any Award or the exercise thereof, at the date of grant or thereafter
(subject to Section 10), such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine. Without limiting the scope of the preceding sentence, the Committee may use
such business criteria and other measures of performance as it may deem appropriate in establishing any performance goals applicable to an Award, and any such performance goals may differ among Awards granted to any one Participant or to different
Participants. To the extent provided in an Award Agreement, the Committee may exercise its discretion to reduce or increase the amounts payable under any Award. 

  
 8 

 (b) Options. The Committee is authorized to grant Options, which may be designated as
either ISOs or Nonstatutory Options, to Eligible Persons on the following terms and conditions: 
 (i) Exercise Price. Each Award
Agreement evidencing an Option shall state the exercise price per share of Stock (the “Exercise Price”) established by the Committee; provided, however, that except as provided in
Section 6(j) or in Section 8, the Exercise Price of an Option shall not be less than the greater of (A) the par value per share of the Stock or (B) 100% of the Fair Market Value per share of
the Stock as of the date of grant of the Option (or in the case of an ISO granted to an individual who owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or its parent or any of its
subsidiaries, 110% of the Fair Market Value per share of the Stock on the date of grant). Notwithstanding the foregoing, the Exercise Price of a Nonstatutory Option may be less than 100% of the Fair Market Value per share of Stock as of the date of
grant of the Option if the Option (1) does not provide for a deferral of compensation by reason of satisfying the short-term deferral exception set forth in the Nonqualified Deferred Compensation Rules or (2) provides for a deferral of
compensation and is compliant with the Nonqualified Deferred Compensation Rules. 
 (ii) Time and Method of Exercise; Other Terms.
The Committee shall determine the methods by which the Exercise Price may be paid or deemed to be paid, the form of such payment, including cash or cash equivalents, Stock (including previously owned shares or through a cashless exercise, i.e.,
“net settlement”, a broker-assisted exercise, or other reduction of the amount of shares otherwise issuable pursuant to the Option), other Awards or awards granted under other plans of the Company or any Affiliate, other property, or any
other legal consideration the Committee deems appropriate (including notes or other contractual obligations of Participants to make payment on a deferred basis), the methods by or forms in which Stock will be delivered or deemed to be delivered to
Participants, including the delivery of Restricted Stock subject to Section 6(d), and any other terms and conditions of any Option. In the case of an exercise whereby the Exercise Price is paid with Stock, such Stock shall
be valued based on the Stock’s Fair Market Value as of the date of exercise. No Option may be exercisable for a period of more than ten years following the date of grant of the Option (or in the case of an ISO granted to an individual who owns
stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or its parent or any of its subsidiaries, for a period of more than five years following the date of grant of the ISO). 

(iii) ISOs. The terms of any ISO granted under the Plan shall comply in all respects with the provisions of Section 422 of the
Code. ISOs may only be granted to Eligible Persons who are employees of the Company or employees of a parent or any subsidiary corporation of the Company. Except as otherwise provided in Section 8, no term of the Plan
relating to ISOs (including any SAR in tandem therewith) shall be interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be exercised, so as to disqualify either the Plan or any ISO under Section 422 of
the Code, unless the Participant has first requested the change that will result in such disqualification. ISOs shall not be granted more than ten years after the earlier of the adoption of the Plan or the approval of the Plan by the Company’s
stockholders. Notwithstanding the foregoing, to the extent that the aggregate Fair Market Value of shares of Stock subject to an ISO and the aggregate Fair Market Value of shares 

  
 9 

 
of stock of any parent or subsidiary corporation (within the meaning of Sections 424(e) and (f) of the Code) subject to any other incentive stock options of the Company or a parent or
subsidiary corporation (within the meaning of Sections 424(e) and (f) of the Code) that are exercisable for the first time by a Participant during any calendar year exceeds $100,000, or such other amount as may be prescribed under
Section 422 of the Code, such excess shall be treated as Nonstatutory Options in accordance with the Code. As used in the previous sentence, Fair Market Value shall be determined as of the date the ISO is granted. If a Participant shall make
any disposition of shares of Stock issued pursuant to an ISO under the circumstances described in Section 421(b) of the Code (relating to disqualifying dispositions), the Participant shall notify the Company of such disposition within the time
provided to do so in the applicable award agreement. 
 (c) SARs. The Committee is authorized to grant SARs to Eligible Persons on
the following terms and conditions: 
 (i) Right to Payment. An SAR is a right to receive, upon exercise thereof, the excess of
(A) the Fair Market Value of one share of Stock on the date of exercise over (B) the grant price of the SAR as determined by the Committee. 

(ii) Grant Price. Each Award Agreement evidencing an SAR shall state the grant price per share of Stock established by the Committee;
provided, however, that except as provided in Section 6(j) or in Section 8, the grant price per share of Stock subject to an SAR shall not be less than the greater of (A) the par
value per share of the Stock or (B) 100% of the Fair Market Value per share of the Stock as of the date of grant of the SAR. Notwithstanding the foregoing, the grant price of an SAR may be less than 100% of the Fair Market Value per share of Stock
subject to an SAR as of the date of grant of the SAR if the SAR (1) does not provide for a deferral of compensation by reason of satisfying the short-term deferral exception set forth in the Nonqualified Deferred Compensation Rules or
(2) provides for a deferral of compensation and is compliant with the Nonqualified Deferred Compensation Rules. 
 (iii) Method of
Exercise and Settlement; Other Terms. The Committee shall determine the form of consideration payable upon settlement, the method by or forms in which Stock (if any) will be delivered or deemed to be delivered to Participants, and any other
terms and conditions of any SAR. SARs may be either free-standing or granted in tandem with other Awards. No SAR may be exercisable for a period of more than ten years following the date of grant of the SAR. 

(iv) Rights Related to Options. An SAR granted in connection with an Option shall entitle a Participant, upon exercise, to surrender
that Option or any portion thereof, to the extent unexercised, and to receive payment of an amount determined by multiplying (A) the difference obtained by subtracting the Exercise Price with respect to a share of Stock specified in the related
Option from the Fair Market Value of a share of Stock on the date of exercise of the SAR, by (B) the number of shares as to which that SAR has been exercised. The Option shall then cease to be exercisable to the extent surrendered. SARs granted
in connection with an Option shall be subject to the terms and conditions of the Award Agreement governing the Option, which shall provide that the SAR is exercisable only at such time or times and only to the extent that the related Option is
exercisable and shall not be transferable except to the extent that the related Option is transferrable. 

  
 10 

 (d) Restricted Stock. The Committee is authorized to grant Restricted Stock to Eligible
Persons on the following terms and conditions: 
 (i) Restrictions. Restricted Stock shall be subject to such restrictions on
transferability, risk of forfeiture and other restrictions, if any, as the Committee may impose. Except as provided in Section 7(a)(iii) and Section 7(a)(iv), during the restricted period
applicable to the Restricted Stock, the Restricted Stock may not be sold, transferred, pledged, hedged, hypothecated, margined or otherwise encumbered by the Participant. 

(ii) Dividends and Splits. As a condition to the grant of an Award of Restricted Stock, the Committee may allow a Participant to
elect, or may require, that any cash dividends paid on a share of Restricted Stock be automatically reinvested in additional shares of Restricted Stock, applied to the purchase of additional Awards or deferred without interest to the date of vesting
of the associated Award of Restricted Stock. Unless otherwise determined by the Committee and specified in the applicable Award Agreement, Stock distributed in connection with a Stock split or Stock dividend, and other property (other than cash)
distributed as a dividend, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock with respect to which such Stock or other property has been distributed. 

(e) Restricted Stock Units. The Committee is authorized to grant Restricted Stock Units to Eligible Persons on the following terms and
conditions: 
 (i) Award and Restrictions. Restricted Stock Units shall be subject to such restrictions (which may include a risk of
forfeiture) as the Committee may impose. 
 (ii) Settlement. Settlement of vested Restricted Stock Units shall occur upon vesting or
upon expiration of the deferral period specified for such Restricted Stock Units by the Committee (or, if permitted by the Committee, as elected by the Participant). Restricted Stock Units shall be settled by delivery of (A) a number of shares
of Stock equal to the number of Restricted Stock Units for which settlement is due, or (B) cash in an amount equal to the Fair Market Value of the specified number of shares of Stock equal to the number of Restricted Stock Units for which
settlement is due, or a combination thereof, as determined by the Committee at the date of grant or thereafter. 
 (f) Stock Awards.
The Committee is authorized to grant Stock Awards to Eligible Persons as a bonus, as additional compensation, or in lieu of cash compensation any such Eligible Person is otherwise entitled to receive, in such amounts and subject to such other terms
as the Committee in its discretion determines to be appropriate. 
 (g) Dividend Equivalents. The Committee is authorized to grant
Dividend Equivalents to Eligible Persons, entitling any such Eligible Person to receive cash, Stock, other Awards, or other property equal in value to dividends or other distributions paid with respect to a specified number of shares of Stock.
Dividend Equivalents may be awarded on a free-standing basis or in connection with another Award (other than an Award of Restricted Stock or a Stock Award). The Committee may provide that Dividend Equivalents shall be paid or distributed when
accrued or at a later specified date and, if distributed at a later date, may be deemed to have been reinvested in additional Stock, Awards, or other investment vehicles or accrued in a 

  
 11 

 
bookkeeping account without interest, and subject to such restrictions on transferability and risks of forfeiture, as the Committee may specify. With respect to Dividend Equivalents granted in
connection with another Award, absent a contrary provision in the Award Agreement, such Dividend Equivalents shall be subject to the same restrictions and risk of forfeiture as the Award with respect to which the dividends accrue and shall not be
paid unless and until such Award has vested and been earned. 
 (h) Other Stock-Based Awards. The Committee is authorized, subject to
limitations under applicable law, to grant to Eligible Persons such other Awards that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, Stock, as deemed by the Committee to be
consistent with the purposes of the Plan, including convertible or exchangeable debt securities, other rights convertible or exchangeable into Stock, purchase rights for Stock, Awards with value and payment contingent upon performance of the Company
or any other factors designated by the Committee, and Awards valued by reference to the book value of Stock or the value of securities of, or the performance of, specified Affiliates of the Company. The Committee shall determine the terms and
conditions of such Other Stock-Based Awards. Stock delivered pursuant to an Other-Stock Based Award in the nature of a purchase right granted under this Section 6(h) shall be purchased for such consideration, paid for at
such times, by such methods, and in such forms, including cash, Stock, other Awards, or other property, as the Committee shall determine. 

(i) Cash Awards. The Committee is authorized to grant Cash Awards, on a free-standing basis or as an element of, a supplement to, or in
lieu of any other Award under the Plan to Eligible Persons in such amounts and subject to such other terms as the Committee in its discretion determines to be appropriate. 

(j) Substitute Awards; No Repricing. Awards may be granted in substitution or exchange for any other Award granted under the Plan or
under another plan of the Company or an Affiliate or any other right of an Eligible Person to receive payment from the Company or an Affiliate. Awards may also be granted under the Plan in substitution for awards held by individuals who become
Eligible Persons as a result of a merger, consolidation or acquisition of another entity or the assets of another entity by or with the Company or an Affiliate. Such Substitute Awards referred to in the immediately preceding sentence that are
Options or SARs may have an exercise price that is less than the Fair Market Value of a share of Stock on the date of the substitution if such substitution complies with the Nonqualified Deferred Compensation Rules and other applicable laws and
exchange rules. Except as provided in this Section 6(j) or in Section 8, without the approval of the stockholders of the Company, the terms of outstanding Awards may not be amended to
(i) reduce the Exercise Price or grant price of an outstanding Option or SAR, (ii) grant a new Option, SAR or other Award in substitution for, or upon the cancellation of, any previously granted Option or SAR that has the effect of
reducing the Exercise Price or grant price thereof, (iii) exchange any Option or SAR for Stock, cash or other consideration when the Exercise Price or grant price per share of Stock under such Option or SAR exceeds the Fair Market Value of a
share of Stock or (iv) take any other action that would be considered a “repricing” of an Option or SAR under the applicable listing standards of the national securities exchange on which the Stock is listed (if any). 

  
 12 

 7. Certain Provisions Applicable to Awards. 

(a) Limit on Transfer of Awards. 

(i) Except as provided in Sections 7(a)(iii) and (iv), each Option and SAR shall be exercisable only by the Participant during
the Participant’s lifetime, or by the person to whom the Participant’s rights shall pass by will or the laws of descent and distribution. Notwithstanding anything to the contrary in this Section 7(a), an ISO shall
not be transferable other than by will or the laws of descent and distribution. 
 (ii) Except as provided in Sections 7(a)(i),
(iii) and (iv), no Award, other than a Stock Award, and no right under any such Award, may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant and any such purported assignment,
alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate. 

(iii) To the extent specifically provided by the Committee, an Award may be transferred by a Participant without consideration to immediate
family members or related family trusts, limited partnerships or similar entities or on such terms and conditions as the Committee may from time to time establish. 

(iv) An Award may be transferred pursuant to a domestic relations order entered or approved by a court of competent jurisdiction upon
delivery to the Company of a written request for such transfer and a certified copy of such order. 
 (b) Form and Timing of Payment
under Awards; Deferrals. Subject to the terms of the Plan and any applicable Award Agreement, payments to be made by the Company or any of its Affiliates upon the exercise or settlement of an Award may be made in such forms as the Committee
shall determine in its discretion, including cash, Stock, other Awards or other property, and may be made in a single payment or transfer, in installments, or on a deferred basis (which may be required by the Committee or permitted at the election
of the Participant on terms and conditions established by the Committee); provided, however, that any such deferred or installment payments will be set forth in the Award Agreement. Payments may include, without limitation, provisions
for the payment or crediting of reasonable interest on installment or deferred payments or the grant or crediting of Dividend Equivalents or other amounts in respect of installment or deferred payments denominated in Stock. 

(c) Evidencing Stock. The Stock or other securities of the Company delivered pursuant to an Award may be evidenced in any manner deemed
appropriate by the Committee in its sole discretion, including in the form of a certificate issued in the name of the Participant or by book entry, electronic or otherwise, and shall be subject to such stop transfer orders and other restrictions as
the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Stock or other securities are then listed, and any applicable federal, state or other laws, and the
Committee may cause a legend or legends to be inscribed on any such certificates to make appropriate reference to such restrictions. Further, if certificates representing Restricted Stock are registered in the name of the Participant, the Company
may retain physical possession of the certificates and may require that the Participant deliver a stock power to the Company, endorsed in blank, related to the Restricted Stock. 

  
 13 

 (d) Consideration for Grants. Awards may be granted for such consideration, including
services, as the Committee shall determine, but shall not be granted for less than the minimum lawful consideration. 
 (e) Additional
Agreements. Each Eligible Person to whom an Award is granted under the Plan may be required to agree in writing, as a condition to the grant of such Award or otherwise, to subject an Award that is exercised or settled following such Eligible
Person’s termination of employment or service to a general release of claims and/or a noncompetition or other restricted covenant agreement in favor of the Company and its Affiliates, with the terms and conditions of such agreement(s) to be
determined in good faith by the Committee. 
 8. Subdivision or Consolidation; Recapitalization; Change in Control; Reorganization.

 (a) Existence of Plans and Awards. The existence of the Plan and the Awards granted hereunder shall not affect in any way the
right or power of the Company, the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of
the Company, any issue of debt or equity securities ahead of or affecting Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or
any other corporate act or proceeding. 
 (b) Additional Issuances. Except as expressly provided herein, the issuance by the Company
of shares of stock of any class, including upon conversion of shares or obligations of the Company convertible into such shares or other securities, and in any case whether or not for fair value, shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number of shares of Stock subject to Awards theretofore granted or the purchase price per share of Stock, if applicable. 

(c) Subdivision or Consolidation of Shares. The terms of an Award and the share limitations under the Plan shall be subject to
adjustment by the Committee from time to time, in accordance with the following provisions: 
 (i) If at any time, or from time to time,
the Company shall subdivide as a whole (by reclassification, by a Stock split, by the issuance of a distribution on Stock payable in Stock, or otherwise) the number of shares of Stock then outstanding into a greater number of shares of Stock or in
the event the Company distributes an extraordinary cash dividend, then, as appropriate (A) the maximum number of shares of Stock available for delivery with respect to Awards and applicable limitations with respect to Awards provided in
Section 4 and Section 5 (other than cash limits) shall be increased proportionately, and the kind of shares or other securities available for the Plan shall be appropriately adjusted, (B) the
number of shares of Stock (or other kind of shares or securities) that may be acquired under any then outstanding Award shall be increased proportionately, and (C) the price (including the Exercise Price or grant price) for each share of Stock
(or other kind of shares or securities) subject to then outstanding Awards shall be reduced proportionately, without changing the aggregate purchase price or value 

  
 14 

 
as to which outstanding Awards remain exercisable or subject to restrictions; provided, however, that in the case of an extraordinary cash dividend that is not an Adjustment Event, the adjustment
to the number of shares of Stock and the Exercise Price or grant price, as applicable, with respect to an outstanding Option or SAR may be made in such other manner as the Committee may determine that is permitted pursuant to applicable tax and
other laws, rules and regulations. 
 (ii) If at any time, or from time to time, the Company shall consolidate as a whole (by
reclassification, by reverse Stock split, or otherwise) the number of shares of Stock then outstanding into a lesser number of shares of Stock, then, as appropriate (A) the maximum number of shares of Stock available for delivery with
respect to Awards and applicable limitations with respect to Awards provided in Section 4 and Section 5 (other than cash limits) shall be decreased proportionately, and the kind of shares or other
securities available for the Plan shall be appropriately adjusted, (B) the number of shares of Stock (or other kind of shares or securities) that may be acquired under any then outstanding Award shall be decreased proportionately, and
(C) the price (including the Exercise Price or grant price) for each share of Stock (or other kind of shares or securities) subject to then outstanding Awards shall be increased proportionately, without changing the aggregate purchase price or
value as to which outstanding Awards remain exercisable or subject to restrictions. 
 (d) Recapitalization. In the event of any
change in the capital structure or business of the Company or other corporate transaction or event that would be considered an “equity restructuring” within the meaning of ASC Topic 718 and, in each case, that would result in an additional
compensation expense to the Company pursuant to the provisions of ASC Topic 718, if adjustments to Awards with respect to such event were discretionary or otherwise not required (each such an event, an “Adjustment Event”),
then the Committee shall equitably adjust (i) the aggregate number or kind of shares that thereafter may be delivered under the Plan, (ii) the number or kind of shares or other property (including cash) subject to an Award, (iii) the
terms and conditions of Awards, including the purchase price or Exercise Price of Awards and performance goals, as applicable, and (iv) the applicable limitations with respect to Awards provided in Section 4 and
Section 5 (other than cash limits) to equitably reflect such Adjustment Event (“Equitable Adjustments”). In the event of any change in the capital structure or business of the Company or other
corporate transaction or event that would not be considered an Adjustment Event, and is not otherwise addressed in this Section 8, the Committee shall have complete discretion to make Equitable Adjustments (if any) in such
manner as it deems appropriate with respect to such other event. 
 (e) Change in Control and Other Events. Except to the extent
otherwise provided in any applicable Award Agreement, vesting of any Award shall not occur solely upon the occurrence of a Change in Control and, in the event of a Change in Control or other changes in the Company or the outstanding Stock by reason
of a recapitalization, reorganization, merger, consolidation, combination, exchange or other relevant change occurring after the date of the grant of any Award, the Committee, acting in its sole discretion without the consent or approval of any
holder, may exercise any power enumerated in Section 3 (including the power to accelerate vesting, waive any forfeiture conditions or otherwise modify or adjust any other condition or limitation regarding an Award) and may
also effect one or more of the following alternatives, which may vary among individual holders and which may vary among Awards held by any individual holder:

 (i) accelerate the time of exercisability of an Award so that such Award may be exercised in full
or in part for a limited period of time on or before a date specified by the Committee, after which specified date all unexercised Awards and all rights of holders thereunder shall terminate; 

(ii) redeem in whole or in part outstanding Awards by requiring the mandatory surrender to the Company by selected holders of some or all of
the outstanding Awards held by such holders (irrespective of whether such Awards are then vested or exercisable) as of a date, specified by the Committee, in which event the Committee shall thereupon cancel such Awards and pay to each holder an
amount of cash or other consideration per Award (other than a Dividend Equivalent or Cash Award, which the Committee may separately require to be surrendered in exchange for cash or other consideration determined by the Committee in its discretion)
equal to the Change in Control Price, less the Exercise Price with respect to an Option and less the grant price with respect to a SAR, as applicable to such Awards; provided, however, that to the extent the Exercise Price of an Option
or the grant price of an SAR exceeds the Change in Control Price, such Award may be cancelled for no consideration; 
 (iii) cancel Awards
that remain subject to a restricted period as of the date of a Change in Control or other such event without payment of any consideration to the Participant for such Awards; or 

(iv) make such adjustments to Awards then outstanding as the Committee deems appropriate to reflect such Change in Control or other such event
(including the substitution, assumption, or continuation of Awards by the successor company or a parent or subsidiary thereof); 
 provided,
however, that so long as the event is not an Adjustment Event, the Committee may determine in its sole discretion that no adjustment is necessary to Awards then outstanding. If an Adjustment Event occurs, this
Section 8(e) shall only apply to the extent it is not in conflict with Section 8(d). 

9. General Provisions. 

(a) Tax Withholding. The Company and any of its Affiliates are authorized to withhold from any Award granted, or any payment relating
to an Award, including from a distribution of Stock, taxes due or potentially payable in connection with any transaction involving an Award, and to take such other action as the Committee may deem advisable to enable the Company, its Affiliates and
Participants to satisfy the payment of withholding taxes and other tax obligations relating to any Award in such amounts as may be determined by the Committee. The Committee shall determine, in its sole discretion, the form of payment acceptable for
such tax withholding obligations, including the delivery of cash or cash equivalents, Stock (including previously owned shares, net settlement, a broker-assisted sale, or other cashless withholding or reduction of the amount of shares otherwise
issuable or delivered pursuant to the Award), other property, or any other legal consideration the Committee deems appropriate. Any determination made by the Committee to allow a Participant who is subject to Rule
16b-3 to pay taxes with shares of Stock through net settlement or previously owned shares 

  
 16 

 
shall be approved by either a committee made up of solely two or more Qualified Members or the full Board. If such tax withholding amounts are satisfied through net settlement or previously owned
shares, the maximum number of shares of Stock that may be so withheld or surrendered shall be the number of shares of Stock that have an aggregate Fair Market Value on the date of withholding or surrender equal to the aggregate amount of such tax
liabilities determined based on the greatest withholding rates for federal, state, foreign and/or local tax purposes, including payroll taxes, that may be utilized without creating adverse accounting treatment for the Company with respect to such
Award, as determined by the Committee. 
 (b) Limitation on Rights Conferred under Plan. Neither the Plan nor any action taken
hereunder shall be construed as (i) giving any Eligible Person or Participant the right to continue as an Eligible Person or Participant or in the employ or service of the Company or any of its Affiliates, (ii) interfering in any way with
the right of the Company or any of its Affiliates to terminate any Eligible Person’s or Participant’s employment or service relationship at any time, (iii) giving an Eligible Person or Participant any claim to be granted any Award
under the Plan or to be treated uniformly with other Participants and/or employees and/or other service providers, or (iv) conferring on a Participant any of the rights of a stockholder of the Company unless and until the Participant is duly
issued or transferred shares of Stock in accordance with the terms of an Award. 
 (c) Governing Law; Submission to Jurisdiction. All
questions arising with respect to the provisions of the Plan and Awards shall be determined by application of the laws of the State of Delaware, without giving effect to any conflict of law provisions thereof, except to the extent Delaware law is
preempted by federal law. The obligation of the Company to sell and deliver Stock hereunder is subject to applicable federal and state laws and to the approval of any governmental authority required in connection with the authorization, issuance,
sale, or delivery of such Stock. With respect to any claim or dispute related to or arising under the Plan, the Company and each Participant who accepts an Award hereby consent to the exclusive
jurisdiction, forum and venue of the state and federal courts located in Houston, Texas. 
 (d) Severability and Reformation. If any
provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such
provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision
shall be stricken as to such jurisdiction, person or Award and the remainder of the Plan and any such Award shall remain in full force and effect. If any of the terms or provisions of the Plan or any Award Agreement conflict with the requirements of
Rule 16b-3 (as those terms or provisions are applied to Eligible Persons who are subject to Section 16 of the Exchange Act) or Section 422 of the Code (with respect to ISOs), then those conflicting
terms or provisions shall be deemed inoperative to the extent they so conflict with the requirements of Rule 16b-3 (unless the Board or the Committee, as appropriate, has expressly determined that the Plan or
such Award should not comply with Rule 16b-3) or Section 422 of the Code, in each case, only to the extent Rule 16b-3 and such sections of the Code are applicable.
With respect to ISOs, if the Plan does not contain any provision required to be included herein under Section 422 of the Code, that provision shall be deemed to be incorporated herein with the same force and effect as if that provision had been
set out at length herein; provided, further, that, to the extent any Option that is intended to qualify as an ISO cannot so qualify, that Option (to that extent) shall be deemed a Nonstatutory Option for all purposes of the Plan. 

  
 17 

 (e) Unfunded Status of Awards; No Trust or Fund Created. The Plan is intended to
constitute an “unfunded” plan for certain incentive awards. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a
Participant or any other person. To the extent that any person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the
Company or such Affiliate. 
 (f) Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board nor its submission to the
stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board or a committee thereof to adopt such other incentive arrangements as it may deem desirable. Nothing contained in the Plan shall be
construed to prevent the Company or any of its Affiliates from taking any corporate action which is deemed by the Company or such Affiliate to be appropriate or in its best interest, whether or not such action would have an adverse effect on the
Plan or any Award made under the Plan. No employee, beneficiary or other person shall have any claim against the Company or any of its Affiliates as a result of any such action. 

(g) Fractional Shares. No fractional shares of Stock shall be issued or delivered pursuant to the Plan or any Award, and the Committee
shall determine in its sole discretion whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional shares of Stock or whether such fractional shares of Stock or any rights thereto shall be cancelled,
terminated, or otherwise eliminated with or without consideration. 
 (h) Interpretation. Headings are given to the Sections and
subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof. Words in the masculine gender
shall include the feminine gender, and, where appropriate, the plural shall include the singular and the singular shall include the plural. In the event of any conflict between the terms and conditions of an Award Agreement and the Plan, the
provisions of the Plan shall control. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth
immediately following such word or to similar items or matters, whether or not non-limiting language (such as “without limitation”, “but not limited to”, or words of similar import) is used
with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter. References herein to any agreement, instrument or
other document means such agreement, instrument or other document as amended, supplemented and modified from time to time to the extent permitted by the provisions thereof and not prohibited by the Plan. 

  
 18 

 (i) Facility of Payment. Any amounts payable hereunder to any individual under legal
disability or who, in the judgment of the Committee, is unable to manage properly his financial affairs, may be paid to the legal representative of such individual, or may be applied for the benefit of such individual in any manner that the
Committee may select, and the Company shall be relieved of any further liability for payment of such amounts. 
 (j) Conditions to
Delivery of Stock. Nothing herein or in any Award Agreement shall require the Company to issue any shares with respect to any Award if that issuance would, in the opinion of counsel for the Company, constitute a violation of the Securities Act,
any other applicable statute or regulation, or the rules of any applicable securities exchange or securities association, as then in effect. In addition, each Participant who receives an Award under the Plan shall not sell or otherwise dispose of
Stock that is acquired upon grant, exercise or vesting of an Award in any manner that would constitute a violation of any applicable federal or state securities laws, the Plan or the rules, regulations or other requirements of the SEC or any stock
exchange upon which the Stock is then listed. At the time of any exercise of an Option or SAR, or at the time of any grant of any other Award, the Company may, as a condition precedent to the exercise of such Option or SAR or settlement of any other
Award, require from the Participant (or in the event of his or her death, his or her legal representatives, heirs, legatees, or distributees) such written representations, if any, concerning the holder’s intentions with regard to the retention
or disposition of the shares of Stock being acquired pursuant to the Award and such written covenants and agreements, if any, as to the manner of disposal of such shares as, in the opinion of counsel to the Company, may be necessary to ensure that
any disposition by that holder (or in the event of the holder’s death, his or her legal representatives, heirs, legatees, or distributees) will not involve a violation of the Securities Act, any other applicable state or federal statute or
regulation, or any rule of any applicable securities exchange or securities association, as then in effect. Stock or other securities shall not be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to
the Plan or the applicable Award Agreement (including any Exercise Price, grant price, or tax withholding) is received by the Company. 

(k) Section 409A of the Code. It is the general intention, but not the obligation, of the Committee to design Awards to comply with or
to be exempt from the Nonqualified Deferred Compensation Rules, and Awards will be operated and construed accordingly. Neither this Section 9(k) nor any other provision of the Plan is or contains a representation to any
Participant regarding the tax consequences of the grant, vesting, exercise, settlement, or sale of any Award (or the Stock underlying such Award) granted hereunder, and should not be interpreted as such. In no event shall the Company be liable for
all or any portion of any taxes, penalties, interest or other expenses that may be incurred by the Participant on account of non-compliance with the Nonqualified Deferred Compensation Rules. Notwithstanding
any provision in the Plan or an Award Agreement to the contrary, in the event that a “specified employee” (as defined under the Nonqualified Deferred Compensation Rules) becomes entitled to a payment under an Award that would be subject to
additional taxes and interest under the Nonqualified Deferred Compensation Rules if the Participant’s receipt of such payment or benefits is not delayed until the earlier of (i) the date of the Participant’s death, or (ii) the
date that is six months after the Participant’s “separation from service,” as defined under the Nonqualified Deferred Compensation Rules (such date, the “Section 409A Payment
Date”), then such payment or benefit shall not be provided to the Participant until the Section 409A Payment Date. Any amounts subject to the preceding sentence that would otherwise be payable prior to the Section 409A Payment
Date will be aggregated and paid in a lump sum without interest on the Section 409A Payment Date. The applicable provisions of the Nonqualified Deferred Compensation Rules are hereby incorporated by reference and shall control over any Plan or
Award Agreement provision in conflict therewith. 

  
 19 

 (l) Clawback. The Plan and all Awards granted hereunder are subject to any written
clawback policies that the Company, with the approval of the Board or an authorized committee thereof, may adopt either prior to or following the Effective Date, including any policy adopted to conform to the Dodd-Frank Wall Street Reform and
Consumer Protection Act of 2010 and rules promulgated thereunder by the SEC and that the Company determines should apply to Awards. Any such policy may subject a Participant’s Awards and amounts paid or realized with respect to Awards to
reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur, including an accounting restatement due to the Company’s material noncompliance with financial reporting regulations or other events or
wrongful conduct specified in any such clawback policy. 
 (m) Status under ERISA. The Plan shall not constitute an “employee
benefit plan” for purposes of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended. 
 (n) Plan
Effective Date and Term. The Plan was adopted by the Board to be effective on the Effective Date. No Awards may be granted under the Plan on and after the tenth anniversary of the Effective Date. However, any Award granted prior to such
termination (or any earlier termination pursuant to Section 10), and the authority of the Board or Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights
under such Award in accordance with the terms of the Plan, shall extend beyond such termination until the final disposition of such Award. 

10. Amendments to the Plan and Awards. The Committee may amend, alter, suspend, discontinue or terminate any Award or Award
Agreement, the Plan or the Committee’s authority to grant Awards without the consent of stockholders or Participants, except that any amendment or alteration to the Plan, including any increase in any share limitation, shall be subject to the
approval of the Company’s stockholders not later than the annual meeting next following such Committee action if such stockholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated
quotation system on which the Stock may then be listed or quoted, and the Committee may otherwise, in its discretion, determine to submit other changes to the Plan to stockholders for approval; provided, that, without the consent of an
affected Participant, no such Committee action may materially and adversely affect the rights of such Participant under any previously granted and outstanding Award. For purposes of clarity, any adjustments made to Awards pursuant to
Section 8 will be deemed not to materially and adversely affect the rights of any Participant under any previously granted and outstanding Award and therefore may be made without the consent of affected Participants.
