COUPA SOFTWARE INCORPORATED 

2016 EMPLOYEE STOCK PURCHASE PLAN 

(AS ADOPTED EFFECTIVE AS OF THE
DATE OF THE INITIAL PUBLIC OFFERING) 
  







 COUPA SOFTWARE INCORPORATED 

2016 EMPLOYEE STOCK PURCHASE PLAN 

SECTION 1. PURPOSE OF THE PLAN. 
 The
Board adopted the Plan effective as of the IPO Date. The purpose of the Plan is to provide Eligible Employees with an opportunity to increase their proprietary interest in the success of the Company by purchasing Stock from the Company on
favorable terms and to pay for such purchases through payroll deductions or other approved contributions.
 SECTION 2. ADMINISTRATION OF THE PLAN.

 (a) 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 Stock is traded, and shall have the authority and be responsible for such functions as have been assigned to it. 

(b) Powers of the 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 interpret the Plan and make all other policy decisions relating to the operation of the Plan. The Administrator may adopt such rules, guidelines and forms as it deems appropriate to implement
the Plan.
 (c) Effects of Administrator’s Decisions. The Administrator’s decisions, determinations and interpretations
shall be final and binding on all interested parties. 
 (d) 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). 
 SECTION 3. STOCK OFFERED UNDER THE PLAN. 

(a) Authorized Shares. The number of shares of Stock available for purchase under the Plan shall be 818,750 shares of the
Company’s Stock (subject to adjustment pursuant to Subsection (c) below), plus the additional shares described in Subsection (b) below. Shares of Stock issued pursuant to the Plan may be authorized but unissued shares or treasury
shares. 
 (b) Annual Increase in Shares. On the first day of each fiscal year of the Company during the term of the Plan,
commencing on February 1, 2017 and ending on (and including) February 1, 2036, the aggregate number of shares of Stock that may be issued under the Plan shall automatically increase by a number equal to the least of (i) 1% of the total number of
shares of Stock actually issued and outstanding on the last day of the preceding fiscal year, (ii) 1,250,000 shares of Stock (subject to adjustment pursuant to Subsection (c) below), or (iii) a number of shares of Stock determined by the
Board.







 (c) Anti-Dilution Adjustments. In the event that any dividend or other
distribution (whether in the form of cash, stock or other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, reclassification, repurchase, or
exchange of Stock or other securities of the Company, or other similar change in the corporate structure of the Company affecting the Stock and effected without receipt or payment of consideration by the Company occurs, then in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, there will be a proportionate adjustment of the number and class of Stock that may be delivered under the Plan, the Purchase Price per share
and the number and class of Stock covered by each option under the Plan which has not yet been exercised, and the numerical limits of Sections 3(a), 3(b)(ii) and 9(c).

(d) Reorganizations. In the event of a Corporate Reorganization, any Offering Period then in progress may be continued,
assumed or substituted by the surviving entity or its parent. If such acquirer refuses to continue, assume or substitute for any such Offering Period, then a new Purchase Date for such Offering Period(s) will be set prior to the effective
time of the Corporate Reorganization, the Participants’ accumulated contributions will be applied to purchase Stock on such date, and any such Offering Periods shall terminate immediately after such purchase. In the event a new Purchase Date is
set under this Section 3(d), Participants will be given notice of the new Purchase Date. The Plan shall in no event be construed to restrict in any way the Company’s right to undertake a dissolution, liquidation, merger, consolidation or
other reorganization. 
 SECTION 4. ENROLLMENT AND PARTICIPATION. 

(a) Offering Periods and Purchase Periods.
  

	 	(i)	Initial Offering Period and Base Offering Periods. Unless changed by the Administrator, the initial Offering Period (the “Initial Offering Period”) shall begin on the IPO Date and end
on September 15, 2018 and shall consist of four consecutive Purchase Periods beginning on the IPO Date, March 16, 2017, September 16, 2017 and March 16, 2018 and ending on March 15, 2017, September 15, 2017, March 15, 2018 and September 15, 2018 as
applicable. Following commencement of the Initial Offering Period, a new Offering Period of 24 months’ duration shall begin on each March 16 and September 16 and end on the March 15 or September 15, as applicable, in the
second calendar year after the start of such Offering Period (each, a “Base Offering Period”). Each Base Offering Period shall consist of four consecutive Purchase Periods, each of 6 months’ duration, commencing on
each March 16 and September 16 in the Base Offering Period and ending on the earlier of the next September 15 or March 15, as applicable. Notwithstanding the foregoing, the Administrator may determine that the first Base Offering
Period applicable to the Eligible Employees of a new Participating Company shall commence on any other date specified by the Administrator. The Administrator may change the frequency and duration of the Base Offering Periods as deemed appropriate
from time to time; provided that a Base Offering Period shall in no event be longer than 27 months (or such other period as may be imposed under applicable tax law). The Initial Offering Period and Base Offering Periods are intended to
qualify under Code Section 423. 


  
 2 









	 	(ii)	Additional Offering Periods. At the discretion of the Administrator, additional Offering Periods (the “Additional Offering Periods”) may be conducted under the Plan or, if necessary
or advisable, in the sole discretion of the Administrator, under a separate sub-plan or sub-plans permitting grants to Eligible Employees of certain Participating Companies (each, a “Sub-Plan”). Such Additional Offering
Periods will be designed to achieve desired tax objectives in particular locations outside the United States or to comply with local laws applicable to offerings in such foreign jurisdictions and will not be intended to qualify under Code Section
423. The Administrator shall determine the commencement and duration of each Additional Offering Period, and Additional Offering Periods may be consecutive or overlapping. The other terms and conditions of each Additional Offering Period shall
be those set forth in this Plan document or in the applicable Sub-Plan, with such changes or additional features as the Administrator determines necessary to comply with local law. Each Sub-Plan shall be considered a separate plan from the Plan
(the “Statutory Plan”). The total number of Shares authorized to be issued under the Plan as provided in Section 3 above applies in the aggregate to both the Statutory Plan and any Sub-Plan. Unless otherwise superseded
by the terms of such Sub-Plan, the provisions of this Plan document shall govern the operation of such Sub-Plan. 

  

	 	(iii)	Separate Offerings. The Initial Offering Period, each Base Offering Period and each Additional Offering Period conducted under the Plan or any Sub-Plan is intended to constitute a separate
“offering” for purposes of Code Section 423. 

  

	 	(iv)	Equal Rights and Privileges. To the extent an Offering Period is intended to qualify under Code Section 423, all participants in such Offering Period shall have the same rights and privileges with respect to
their participation in such Offering Period in accordance with Code Section 423 and the regulations thereunder except for differences that may be mandated by local law and are consistent with the requirements of Code Section 423(b)(5).


 (b) Enrollment at IPO. Each individual who qualifies as an Eligible Employee on the IPO Date shall
automatically become a Participant on such day, and shall be considered to have been granted an option to participate in the Initial Offering Period under the Plan at the maximum applicable participation rate. To maintain participation in the
Initial Offering Period, each Participant who was automatically enrolled on the IPO Date must file the prescribed enrollment form with the Company. The enrollment form shall be filed at the prescribed location 

  
 3 








 
by a date specified by the Company, but in no event later than 10 business days after the IPO Date. If a Participant who was automatically enrolled on the IPO Date fails to file such form in
a timely manner, then such Participant shall be deemed to have withdrawn from the Plan under Section 6(a).     
 (c)
Enrollment After IPO. In the case of any individual who qualifies as an Eligible Employee on the first day of any Offering Period other than the Initial Offering Period, he or she may elect to become a Participant on such day by filing
the prescribed enrollment form with the Company. The enrollment form shall be filed at the prescribed location at least 10 business days (or such other period as the Administrator may designate) prior to such day. 

(d) Duration of Participation. Once enrolled in the Plan, a Participant shall continue to participate in the Plan until he
or she: 
  

	 	(i)	Reaches the end of the Offering Period or Purchase Period, as applicable, in which his or her employee contributions were discontinued under Section 5(c) or 9(b); 


 

	 	(ii)	Is deemed to withdraw from the Plan under Subsection (b) above; 

  

	 	(iii)	Withdraws from the Plan under Section 6(a); or 

  

	 	(iv)	Ceases to be an Eligible Employee. 

 A Participant whose employee contributions were discontinued automatically
under Section 9(b) shall automatically resume participation as described therein. In all other cases, a former Participant may again become a Participant, if he or she then is an Eligible Employee, by following the procedure described in
Subsection (c) above. 
 (e) Applicable Offering Period. For purposes of calculating the Purchase Price under Section 8(b),
the applicable Offering Period shall be determined as follows: 
  

	 	(i)	Once a Participant is enrolled in the Plan for an Offering Period, such Offering Period shall continue to apply to him or her until the earliest of (A) the end of such Offering Period, (B) the end of his or her
participation under Subsection (d) above, or (C) re-enrollment for a subsequent Offering Period under Paragraph (ii) or (iii) below. 

  

	 	(ii)	In the event that the Fair Market Value of a Share on the first day of the Offering Period for which the Participant is enrolled is higher than on the first day of any subsequent Offering Period, the Participant shall
automatically be re-enrolled for such subsequent Offering Period. 

  

	 	(iii)	Any other provision of the Plan notwithstanding, the Administrator (at its sole discretion) may determine prior to the commencement of any new Offering Period that all Participants shall be re-enrolled for such new
Offering Period. 


  
 4 









	 	(iv)	When a Participant reaches the end of an Offering Period but his or her participation is to continue, then such Participant shall automatically be re-enrolled for the Offering Period that commences immediately after the
end of the prior Offering Period. 

 SECTION 5. EMPLOYEE CONTRIBUTIONS. 

(a) Commencement of Payroll Deductions. A Participant may purchase shares of Stock under the Plan by means of payroll
deductions or (if so approved by the Administrator with respect to all Participants in a Base Offering Period) other approved contributions in form and substance satisfactory to the Administrator. Payroll deductions or other approved
contributions shall commence as soon as reasonably practicable after the Company has received the prescribed enrollment form. In jurisdictions where payroll deductions are not permitted under local law, Participants may purchase shares of Stock
by making contributions in the form that is acceptable and approved by the Administrator. 
 (b) Amount of Payroll Deductions. An
Eligible Employee shall designate on the prescribed enrollment form the portion of his or her Compensation that he or she elects to have withheld for the purchase of Stock. Such portion shall be a whole percentage of the Eligible
Employee’s Compensation, but not less than 1% nor more than 15%. 
 (c) Reducing Withholding Rate or Discontinuing Payroll
Deductions. If a Participant wishes to reduce his or her rate of payroll withholding, such Participant may do so by filing a new enrollment form with the Company at the prescribed location at any time. The new withholding rate shall be
effective as soon as reasonably practicable after the Company has received such form. The new withholding rate may be 0% or any whole percentage of the Participant’s Compensation, but not more than his or her old withholding rate. No
Participant shall make more than one election under this Subsection (c) during any Purchase Period. (In addition, employee contributions may be discontinued automatically pursuant to Section 9(b).) 

(d) Increasing Withholding Rate. If a Participant wishes to increase his or her rate of payroll withholding, such Participant may
do so by filing a new enrollment form with the Company at the prescribed location at any time. The new withholding rate may be effective on the first day of the next-upcoming Offering Period in which the Participant participates, provided that
the Participant has filed the enrollment form with the Company at the prescribed location at least 10 business days (or such other period as the Administrator may designate) prior to such day. The new withholding rate may be any whole
percentage of the Participant’s Compensation, but not less than 1% nor more than 15%. An increase in a Participant’s rate of payroll withholding may not take effect during an Offering Period. 

SECTION 6. WITHDRAWAL FROM THE PLAN. 

(a) Withdrawal. A Participant may elect to withdraw from the Plan (or, if applicable, from an Offering Period) by filing the
prescribed form with the Company at the prescribed location at any time before a Purchase Date. As soon as reasonably practicable thereafter, payroll deductions or other approved contributions shall cease and the entire amount credited to the
Participant’s Plan Account with respect to such Offering Period shall be refunded to him or her in cash, without interest (except as otherwise required by the laws of the local jurisdiction). No partial withdrawals from an Offering Period
shall be permitted.

  
 5 








 (b) Re-Enrollment After Withdrawal. A former Participant who has withdrawn from the
Plan shall not be a Participant until he or she re-enrolls in the Plan under Section 4(c). Re-enrollment may be effective only at the commencement of an Offering Period. 

SECTION 7. CHANGE IN EMPLOYMENT STATUS. 

(a) Termination of Employment. Termination of employment as an Eligible Employee for any reason, including death, shall be treated
as an automatic withdrawal from the Plan under Section 6(a).
 (b) Transfers of Employment. If a Participant transfers
employment from a Participating Company that is participating in the Initial Offering Period or a Base Offering Period to a Participating Company that is participating in an Additional Offering Period, he or she will immediately cease to participate
in the Initial Offering Period or Base Offering Period as applicable; however, such Participant’s Plan Account will be transferred to the Additional Offering Period, and such Participant will immediately join such Additional Offering Period on
the terms and conditions applicable to such Additional Offering Period, except for any modifications required by applicable law. If a Participant transfers employment from a Participating Company that is participating in an Additional Offering
Period to a Participating Company that is participating in the Initial Offering Period or a Base Offering Period, he or she will continue to participate in the Additional Offering Period until the earlier of (i) the end of such Additional Offering
Period, or (ii) the commencement of the first Base Offering Period in which he or she is eligible. If a Participant transfers employment from a Participating Company to a Related Corporation that is not a Participating Company, he or she shall
be deemed to have withdrawn from the Plan pursuant to Section 6(a). 
 (c) Leave of Absence. For purposes of the Plan, employment
shall not be deemed to terminate when the Participant goes on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by the Company in writing. Employment, however, shall be deemed to terminate on
the first day following three months after the Participant goes on a leave, unless a contract or statute guarantees his or her right to return to work. Employment shall be deemed to terminate in any event when the approved leave ends, unless
the Participant immediately returns to work. 
 (d) Death. In the event of the Participant’s death, the amount credited to
his or her Plan Account shall be paid to a beneficiary designated by him or her for this purpose on the prescribed form or, if none, to the Participant’s estate. Such form shall be valid only if it was filed with the Company at the
prescribed location before the Participant’s death. 
 SECTION 8. PLAN ACCOUNTS AND PURCHASE OF SHARES. 

(a) Plan Accounts. The Company shall maintain a Plan Account on its books in the name of each Participant. Whenever an amount
is deducted from the Participant’s Compensation under the Plan, such amount shall be credited to the Participant’s Plan Account. Amounts credited to Plan Accounts shall not be trust funds and may be commingled with the Company’s
general assets and applied to general corporate purposes. Unless otherwise required by the laws of the local jurisdiction, no interest shall be credited to Plan Accounts.

  
 6 








 (b) Purchase Price. The Purchase Price for each share of Stock purchased on a
Purchase Date shall be the lower of: 
  

	 	(i)	85% of the Fair Market Value of such share on the first day of such Offering Period; or 

  

	 	(ii)	85% of the Fair Market Value of such share on the Purchase Date. 

 (c) Number of Shares
Purchased. On each Purchase Date, each Participant shall be deemed to have elected to purchase the number of shares of Stock calculated in accordance with this Subsection (c), unless the Participant has previously elected to withdraw
from the Offering Period in accordance with Section 6(a). The amount then in the Participant’s Plan Account shall be divided by the Purchase Price, and the number of shares that results shall be purchased from the Company with the
funds in the Participant’s Plan Account. The foregoing number of shares of Stock purchasable by a Participant are subject to the limitations set forth in Section 9. The Administrator may determine with respect to all Participants that
any fractional share, as calculated under this Subsection (c), shall be (i) rounded down to the next lower whole share or (ii) credited as a fractional share. 

(d) Available Shares Insufficient. In the event that the aggregate number of shares that all Participants elect to purchase with
respect to a particular Purchase Period exceeds (i) the number of shares of Stock that were available under Section 3 above for sale under the Plan on the first day of the applicable Offering Period, or (ii) the number of shares that were available
under Section 3 above for sale under the Plan on the applicable Purchase Date, then the number of shares to which each Participant is entitled shall be determined by multiplying the number of shares available for issuance by a fraction. The
numerator of such fraction is the number of shares that such Participant has elected to purchase, and the denominator of such fraction is the number of shares that all Participants have elected to purchase. The Company may make a pro rata
allocation of the shares available on the first day of an applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent
to such date. In the event of a pro-rata allocation under this Section (d), the Administrator may determine in its discretion to continue all Offering Periods then in effect or terminate all Offering Periods then in effect pursuant to
Section 14. 
 (e) Issuance of Stock. The shares of Stock purchased by a Participant under the Plan may be registered in the
name of such Participant, or jointly in the name of such Participant and his or her spouse as joint tenants with the right of survivorship or as community property (with or without the right of survivorship). The Company may permit or require
that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares be retained with
such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. (The two preceding sentences shall apply whether or not the Participant is required to
pay income tax in the United States.) 

  
 7 








 (f) Tax Withholding. To the extent required by applicable federal, state, local or
foreign law, a Participant shall make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations that arise in connection with the Plan. The Company shall not be required to issue any shares of Stock under
the Plan until such obligations, if any, are satisfied. 
 (g) Unused Cash Balances. Subject to the final sentence of Section
8(c), an amount remaining in the Participant’s Plan Account that represents the Purchase Price for any fractional share shall be carried over in the Participant’s Plan Account to the next Purchase Period. Any amount remaining in the
Participant’s Plan Account that represents the Purchase Price for whole shares that could not be purchased by reason of Subsections (c) or (d) above or Section 9(b) shall be refunded to the Participant in cash, without interest
(except as otherwise required by the laws of the local jurisdiction). 
 (h) Stockholder Approval. Any other provision of the
Plan notwithstanding, no shares of Stock shall be purchased under the Plan unless and until the Company’s stockholders have approved the adoption of the Plan. 

SECTION 9. PLAN LIMITATIONS. 
 (a)
Five Percent Limit. Any other provision of the Plan notwithstanding, no Participant shall be granted a right to purchase Stock under the Plan if, immediately after such right is granted, such Participant would own stock possessing 5% or
more of the total combined voting power or value of all classes of stock of the Company or any Related Corporation, applying the stock attribution rules of Code Section 424(d), and including any stock in which the Participant may purchase under
outstanding options as stock owned by such Participant.
 (b) Dollar Limit. As specified by Code Section 423(b)(8), no
Participant shall be entitled to accrue rights to purchase Stock pursuant to any such rights outstanding under the Plan if and to the extent such accrual, when aggregated with (i) rights to purchase Stock accrued under any other right to purchase
Stock under the Plan, and (ii) similar rights accrued under other employee stock purchase plans (within the meaning of Code Section 423) of the Company or any Related Corporation, would otherwise permit such Participant to purchase more than $25,000
worth of Stock of the Company or any Related Corporation (determined on the basis of the Fair Market Value per share on the date such rights are granted, and which, with respect to the Plan, will be determined as of the beginning of the respective
Offering Period) for each calendar year such rights are at any time outstanding. 
 If a Participant is precluded by this
Subsection (b) from purchasing additional Stock under the Plan, then his or her employee contributions shall automatically be discontinued and shall automatically resume at the beginning of the next Purchase Period with a scheduled Purchase
Date in the next calendar year, provided that he or she is an Eligible Employee at the beginning of such Purchase Period. 

  
 8 








 (c) Purchase Period Share Purchase Limit. Any other provision of the Plan
notwithstanding, no Participant shall purchase more than 3,125 shares of Stock with respect to any Purchase Period; provided that the Administrator may, for future Offering Periods, increase or decrease in its absolute discretion, the maximum number
of shares of Stock that a Participant may purchase during each Purchase Period.
 SECTION 10. RIGHTS NOT TRANSFERABLE. 

The rights of any Participant under the Plan, or any Participant’s interest in any Stock or moneys to which he or she may be entitled
under the Plan, shall not be transferable by voluntary or involuntary assignment or by operation of law, or in any other manner other than by beneficiary designation or the laws of descent and distribution. If a Participant in any manner
attempts to transfer, assign or otherwise encumber his or her rights or interest under the Plan, other than by beneficiary designation or the laws of descent and distribution, then such act shall be treated as an election by the Participant to
withdraw from the Plan under Section 6(a). 
 SECTION 11. NO RIGHTS AS AN EMPLOYEE. 

Nothing in the Plan or in any right granted under the Plan shall confer upon the Participant any right to continue in the employ of a
Participating Company for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Participating Companies or of the Participant, which rights are hereby expressly reserved by each, to terminate his or her
employment at any time and for any reason, with or without cause. 
 SECTION 12. NO RIGHTS AS A STOCKHOLDER. 

A Participant shall have no rights as a stockholder with respect to any shares of Stock that he or she may have a right to purchase under the
Plan until such shares have been purchased on the applicable Purchase Date. 
 SECTION 13. SECURITIES LAW REQUIREMENTS. 

Shares of Stock shall not be issued, and the Company shall have no liability for failure to issue shares of Stock, under the Plan unless the
issuance and delivery of such shares comply with (or are exempt from) all applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state securities laws
and regulations, and the regulations of any stock exchange or other securities market on which the Company’s securities may then be traded. 

SECTION 14. AMENDMENT OR DISCONTINUANCE. 

(a) General Rule. The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof,
at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Stock on the next Purchase
Date, or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any 

  
 9 








 
adjustment pursuant to Section 3(c) or (d)). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts which have not been used to
purchase shares of Stock will be returned to the Participants (without interest thereon, except as otherwise required by the laws of the local jurisdiction) as soon as administratively practicable. 

(b) Administrator’s Discretion. Without stockholder consent and without limiting Section 14(a), the Administrator will be
entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll
withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or
accounting and crediting procedures to ensure that amounts applied toward the purchase of Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or
procedures as it determines in its sole discretion advisable which are consistent with the Plan. 
 (c) Accounting
Consideration. In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable,
modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to: 
  

	 	(i)	Amending the Plan to conform with the safe harbor definition under Financial Accounting Standards Board Accounting Standards Codification Topic 718, including with respect to an Offering Period underway at the time;


  

	 	(ii)	Altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price; 


 

	 	(iii)	Shortening any Offering Period by setting a new Purchase Date, including an Offering Period underway at the time of the Administrator’s action; 


 

	 	(iv)	Reducing the maximum percentage of Compensation a Participant may elect to set aside as payroll deductions; and 

  

	 	(v)	Reducing the maximum number of shares of Stock a Participant may purchase during any Purchase Period. 

 Such
modifications or amendments will not require stockholder approval or the consent of any Plan Participants. 
 (d) Stockholder
Approval. Except as provided in Section 3, any increase in the aggregate number of shares of Stock that may be issued under the Plan shall be subject to the approval of the Company’s stockholders. In addition, any other
amendment of the Plan shall be subject to the approval of the Company’s stockholders to the extent required under Section 14(e) or by any applicable law or regulation.

  
 10
