 IMPERVA, INC. 

2003 STOCK PLAN 
 SECTION 1. ESTABLISHMENT AND PURPOSE. 
 The purpose of the Plan is to offer
selected persons an opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, by purchasing Shares of the Company’s Stock. The Plan provides both for the direct award or sale of Shares and for
the grant of Options to purchase Shares. Options granted under the Plan may be Nonstatutory Options or ISOs intended to qualify under Section 422 of the Code. 
 Capitalized terms are defined in Section 13. 
 SECTION 2. ADMINISTRATION. 

(a) Committees of the Board of Directors. The Plan may be administered by one or more Committees. Each Committee shall consist of
one or more members of the Board of Directors who have been appointed by the Board of Directors. Each Committee shall have such authority and be responsible for such functions as the Board of Directors has assigned to it. If no Committee has been
appointed, the entire Board of Directors shall administer the Plan. Notwithstanding the above, if a Committee has been appointed, the entire Board of Directors may also administer the Plan. Any reference to the Board of Directors in the Plan shall
be construed as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular function. 
 (b)
Authority of the Board of Directors. Subject to the provisions of the Plan, the Board of Directors shall have full authority and discretion to take any actions it deems necessary or advisable for the administration of the Plan. All decisions,
interpretations and other actions of the Board of Directors shall be final and binding on all Purchasers, all Optionees and all persons deriving their rights from a Purchaser or Optionee. 
 SECTION 3. ELIGIBILITY. 
 (a) General Rule. Only Employees, Outside
Directors and Consultants shall be eligible for the grant of Nonstatutory Options or the direct award or sale of Shares. Only Employees shall be eligible for the grant of ISOs. 

(b) Ten-Percent Stockholders. A person who owns more than 10% of the total combined voting power of all classes of outstanding
stock of the Company, its Parent or any of its Subsidiaries shall not be eligible for designation as an Optionee or Purchaser unless (i) the Exercise Price is at least 110% of the Fair Market Value of a Share on the date of grant, (ii) the
Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and (iii) in the case of an ISO, such ISO by its terms is not exercisable after the expiration of five years from the date of grant. For purposes of this
Subsection (b), in determining stock ownership, the attribution rules of Section 424(d) of the Code shall be applied. 







 SECTION 4. STOCK SUBJECT TO PLAN. 

(a) Basic Limitation. Not more than 11,674,5971 Shares may be issued under the Plan (subject to Subsection (b) below and Section 8). The number of Shares
that are subject to Options or other rights outstanding at any time under the Plan shall not exceed the number of Shares that then remain available for issuance under the Plan. The Company, during the term of the Plan, shall at all times reserve and
keep available sufficient Shares to satisfy the requirements of the Plan. Shares offered under the Plan may be authorized but unissued Shares or treasury Shares. 

(b) Additional Shares. In the event that any outstanding Option or other right for any reason expires or is
canceled or otherwise terminated, the Shares allocable to the unexercised portion of such Option or other right shall again be available for the purposes of the Plan. In the event that Shares issued under the Plan are reacquired by the Company
pursuant to any forfeiture provision, right of repurchase or right of first refusal, such Shares shall again be available for the purposes of the Plan, except that the aggregate number of Shares which may be issued upon the exercise of ISOs shall in
no event exceed 11,674,5971 Shares (subject to adjustment
pursuant to Section 8). 
 SECTION 5. TERMS AND CONDITIONS OF AWARDS OR SALES. 

(a) Stock Purchase Agreement. Each award or sale of Shares under the Plan (other than upon exercise of an Option) shall be
evidenced by a Stock Purchase Agreement between the Purchaser and the Company. Such award or sale shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent
with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Purchase Agreement. The provisions of the various Stock Purchase Agreements entered into under the Plan need not be identical. 

(b) Duration of Offers and Nontransferability of Rights. Any right to acquire Shares under the Plan (other than an Option) shall
automatically expire if not exercised by the Purchaser within 30 days after the grant of such right was communicated to the Purchaser by the Company. Such right shall not be transferable and shall be exercisable only by the Purchaser to whom such
right was granted. 
 (c) Purchase Price. The Purchase Price of Shares to be offered under the Plan shall not be less
than 85% of the Fair Market Value of such Shares, and a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors shall determine the Purchase Price at its sole discretion. The Purchase Price
shall be payable in a form described in Section 7.

 (d) Withholding Taxes. As a condition to the purchase of Shares, the Purchaser shall
make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such purchase. 

(e) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares awarded or sold under the Plan shall be subject to such
special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the applicable Stock Purchase Agreement and shall apply in
addition to any restrictions that may apply to holders of Shares generally. In the case of a Purchaser who is not an officer of the Company, an Outside Director or a Consultant: 

(i) Any right to repurchase the Purchaser’s Shares at the original Purchase Price (if any) upon termination of the
Purchaser’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the award or sale of the Shares; 

(ii) Any such repurchase right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing
the Shares; and 
 (iii) Any such repurchase right may be exercised only within 90 days after the termination of
the Purchaser’s Service. 
 SECTION 6. TERMS AND CONDITIONS OF OPTIONS. 

(a) Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the
Optionee and the Company. The Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate
for inclusion in a Stock Option Agreement. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. 
 (b) Number of Shares. Each Stock Option Agreement shall specify the number of Shares that are subject to the Option and shall provide for the adjustment of such number in accordance with
Section 8. The Stock Option Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option. 
 (c)
Exercise Price. Each Stock Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by
Section 3(b). The Exercise Price of a Nonstatutory Option shall not be less than 85% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). Subject to the preceding two sentences,
the Exercise Price under any Option shall be determined by the Board of Directors at its sole discretion. The Exercise Price shall be payable in a form described in Section 7. 

(d) Exercisability. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become
exercisable. No Option shall be exercisable 

  
 3 








 
unless the Optionee has delivered an executed copy of the Stock Option Agreement to the Company. In the case of an Optionee who is not an officer of the Company, an Outside Director or a
Consultant, an Option shall become exercisable at least as rapidly as 20% per year over the five-year period commencing on the date of grant. Subject to the preceding sentence, the Board of Directors shall determine the exercisability
provisions of the Stock Option Agreement at its sole discretion. 
 (e) Accelerated Exercisability. Unless the applicable
Stock Option Agreement provides otherwise, all of an Optionee’s Options shall become exercisable in full if (i) the Company is subject to a Change in Control before the Optionee’s Service terminates, (ii) such Options do not
remain outstanding, (iii) such Options are not assumed by the surviving corporation or its parent, (iv) the surviving corporation or its parent does not substitute options with substantially the same terms for such Options, and
(v) the full value of this option (whether or not exercisable) is not settled in cash or cash equivalents. 
 (f) Basic
Term. The Stock Option Agreement shall specify the term of the Option. The term shall not exceed 10 years from the date of grant, and a shorter term may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors
at its sole discretion shall determine when an Option is to expire. 
 (g) Termination of Service (Except by Death). If
an Optionee’s Service terminates for any reason other than the Optionee’s death, then the Optionee’s Options shall expire on the earliest of the following occasions: 

(i) The expiration date determined pursuant to Subsection (f) above; 

(ii) The date 3 months after the termination of the Optionee’s Service for any reason other than Disability, or such
later date as the Board of Directors may determine; or 
 (iii) The date 6 months after the termination of the
Optionee’s Service by reason of Disability, or such other date as the Board of Directors may determine (but not less than six months after the termination of the Optionee’s Service by reason of Disability). 

The Optionee may exercise all or part of the Optionee’s Options at any time before the expiration of such Options under the preceding sentence, but
only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or
vested as a result of the termination). The balance of such Options shall lapse when the Optionee’s Service terminates. In the event that the Optionee dies after the termination of the Optionee’s Service but before the expiration of the
Optionee’s Options, all or part of such Options may be exercised (prior to expiration) by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary
designation, bequest or inheritance, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result 

  
 4 








 
of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination). 

(h) Leaves of Absence. For purposes of Subsection (g) above, Service shall be deemed to continue while the Optionee is on a
bona fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for this purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company). 

(i) Death of Optionee. If an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall expire on the
earlier of the following dates: 
 (i) The expiration date determined pursuant to Subsection (f) above; or

 (ii) The date 12 months after the Optionee’s death, or such later date as the Board of Directors may
determine. 
 All or part of the Optionee’s Options may be exercised at any time before the expiration of such Options under the preceding
sentence by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that such Options had
become exercisable before the Optionee’s death (or became exercisable as a result of the death) and the underlying Shares had vested before the Optionee’s death (or vested as a result of the Optionee’s death). The balance of such
Options shall lapse when the Optionee dies. 
 (j) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares
issued upon exercise of an Option shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in
the applicable Stock Option Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant: 

(i) Any right to repurchase the Optionee’s Shares at the original Exercise Price upon termination of the
Optionee’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the option grant; 
 (ii) Any such right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing the Shares; and 

(iii) Any such right may be exercised only within 90 days after the later of (A) the termination of the
Optionee’s Service or (B) the date of the option exercise. 
 (k) Transferability of Options. An Option shall
be transferable by the Optionee only by (i) a beneficiary designation, (ii) a will or (iii) the laws of descent and distribution, except as provided in the next sentence. If the applicable Stock Option Agreement


  
 5 








 
so provides, an Nonstatutory Option shall also be transferable by the Optionee by (i) a gift to a member of the Optionee’s Immediate Family or (ii) a gift to an inter vivos
or testamentary trust in which members of the Optionee’s Immediate Family have a beneficial interest of more than 50% and which provides that such Nonstatutory Option is to be transferred to the beneficiaries upon the Optionee’s death. An
ISO may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative. Except as expressly provided herein or in the applicable Stock Option Agreement, no Option or interest therein
may be transferred, assigned, pledged or hypothecated by the Optionee during the Optionee’s lifetime, whether by operation of law or otherwise, or be made subject to execution, attachment or similar process. 

(l) Withholding Taxes. As a condition to the exercise of an Option, the Optionee shall make such arrangements as the Board of
Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such exercise. The Optionee shall also make such arrangements as the Board of Directors may require for
the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with the disposition of Shares acquired by exercising an Option. 

(m) No Rights as a Stockholder. An Optionee, or a transferee of an Optionee, shall have no rights as a stockholder with respect to
any Shares covered by the Optionee’s Option until such person becomes entitled to receive such Shares by filing a notice of exercise and paying the Exercise Price pursuant to the terms of such Option. 

(n) Modification, Extension and Assumption of Options. Within the limitations of the Plan, the Board of Directors may modify,
extend or assume outstanding Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options for the same or a different number of Shares and at the same or a
different Exercise Price. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s rights or increase the Optionee’s obligations under such Option. 

SECTION 7. PAYMENT FOR SHARES. 
 (a) General Rule. The entire Purchase Price or Exercise Price of Shares issued under the Plan shall be payable in cash or cash equivalents at the time when such Shares are purchased, except as
otherwise provided in this Section 7. 
 (b) Surrender of Stock. At the discretion of the Board of Directors and to
the extent that a Stock Option Agreement so provides, all or any part of the Exercise Price may be paid by surrendering, or attesting to the ownership of, Shares that are already owned by the Optionee. Such Shares shall be surrendered to the Company
in good form for transfer and shall be valued at their Fair Market Value on the date when the Option is exercised. The Optionee shall not surrender, or attest to the ownership of, Shares in payment of the Exercise Price if such action would cause
the Company to recognize compensation expense (or additional compensation expense) with respect to the Option for financial reporting purposes. 

  
 6 








 (c) Services Rendered. At the discretion of the Board of Directors, Shares may be
awarded under the Plan in consideration of services rendered to the Company, a Parent or a Subsidiary prior to the award. 
 (d)
Promissory Note. At the discretion of the Board of Directors and to the extent that a Stock Option Agreement or Stock Purchase Agreement so provides, all or a portion of the Exercise Price or Purchase Price (as the case may be) of Shares
issued under the Plan may be paid with a full-recourse promissory note. However, the par value of the Shares, if newly issued, shall be paid in cash or cash equivalents. The Shares shall be pledged as security for payment of the principal amount of
the promissory note and interest thereon. The interest rate payable under the terms of the promissory note shall not be less than the minimum rate (if any) required to avoid the imputation of additional interest under the Code. Subject to the
foregoing, the Board of Directors (at its sole discretion) shall specify the term, interest rate, amortization requirements (if any) and other provisions of such note. 
 (e) Exercise/Sale. At the discretion of the Board of Directors and to the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the Company to sell Shares and to deliver all or part of the sales proceeds to the Company in payment of all or part of the Exercise
Price and any withholding taxes. 
 (f) Exercise/Pledge. At the discretion of the Board of Directors and to the extent
that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made all or in part by the delivery (on a form prescribed by the Company) of an irrevocable direction to pledge Shares to a securities broker or lender
approved by the Company, as security for a loan, and to deliver all or part of the loan proceeds to the Company in payment of all or part of the Exercise Price and any withholding taxes. 
 SECTION 8. ADJUSTMENT OF SHARES. 
 (a) General. In the event of a
subdivision of the outstanding Stock, a declaration of a dividend payable in Shares, a declaration of an extraordinary dividend payable in a form other than Shares in an amount that has a material effect on the Fair Market Value of the Stock, a
combination or consolidation of the outstanding Stock into a lesser number of Shares, a recapitalization, a spin-off, a reclassification or a similar occurrence, the Board of Directors shall make appropriate adjustments in one or more of
(i) the number of Shares available for future grants under Section 4, (ii) the number of Shares covered by each outstanding Option or (iii) the Exercise Price under each outstanding Option. 

(b) Mergers and Consolidations. In the event that the Company is a party to a merger or consolidation, outstanding Options shall
be subject to the agreement of merger or consolidation. Such agreement shall provide for: 
 (i) The continuation
of such outstanding Options by the Company (if the Company is the surviving corporation); 

  
 7 








 (ii) The assumption of the Plan and such outstanding Options by the
surviving corporation or its parent; 
 (iii) The substitution by the surviving corporation or its parent of
options with substantially the same terms for such outstanding Options; 
 (iv) The full exercisability of such
outstanding Options and full vesting of the Shares subject to such Options, followed by the cancellation of such Options; or 
 (v) The settlement of the full value of such outstanding Options (whether or not then exercisable) in cash or cash equivalents, followed by the cancellation of such Options. 

(c) Reservation of Rights. Except as provided in this Section 8, an Optionee or Purchaser shall have no rights by reason of
(i) any subdivision or consolidation of shares of stock of any class, (ii) the payment of any dividend or (iii) any other increase or decrease in the number of shares of stock of any class. Any issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option
pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets. 
 SECTION 9. SECURITIES LAW REQUIREMENTS. 

(a) General. Shares shall not be issued 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, including the Israeli securities law and
regulation, if applicable, and the regulations of any stock exchange or other securities market on which the Company’s securities may then be traded. 
 (b) Financial Reports. The Company each year shall furnish to Optionees, Purchasers and stockholders who have received Stock under the Plan its balance sheet and income statement, unless such
Optionees, Purchasers or stockholders are key Employees whose duties with the Company assure them access to equivalent information. Such balance sheet and income statement need not be audited. 

SECTION 10. NO RETENTION RIGHTS. 
 Nothing in the Plan or in any right or Option granted under the Plan shall confer upon the Purchaser or Optionee any right to continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Purchaser or Optionee) or of the Purchaser or Optionee, which rights are hereby expressly reserved by each, to terminate his or her
Service at any time and for any reason, with or without cause. 

  
 8 








 SECTION 11. DURATION AND AMENDMENTS. 

(a) Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by the Board of Directors,
subject to the approval of the Company’s stockholders. If the stockholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, then any grants or exercises of Options or sales of Shares that have already
occurred under the Plan shall be rescinded and no additional grants, exercises or sales shall thereafter be made under the Plan. The Plan shall terminate automatically 10 years after the later of (i) its adoption by the Board of Directors or
(ii) the most recent increase in the number of Shares reserved under Section 4 that was approved by the Company’s stockholders. The Plan may be terminated on any earlier date pursuant to Subsection (b) below. 

(b) Right to Amend or Terminate the Plan. The Board of Directors may amend, suspend or terminate the Plan at any time and for any
reason; provided, however, that any amendment of the Plan shall be subject to the approval of the Company’s stockholders if it (i) increases the number of Shares available for issuance under the Plan (except as provided in Section 8)
or (ii) materially changes the class of persons who are eligible for the grant of ISOs. Stockholder approval shall not be required for any other amendment of the Plan. If the stockholders fail to approve an increase in the number of Shares
reserved under Section 4 within 12 months after its adoption by the Board of Directors, then any grants, exercises or sales that have already occurred in reliance on such increase shall be rescinded and no additional grants, exercises or sales
shall thereafter be made in reliance on such increase. 
 (c) Effect of Amendment or Termination. No Shares shall be
issued or sold under the Plan after the termination thereof, except upon exercise of an Option or exercise of a purchase right, each granted prior to such termination. The termination of the Plan, or any amendment thereof, shall not affect any Share
previously issued or any Option previously granted under the Plan. 
 SECTION 12. DEFINITIONS. 

(a) “Board of Directors” shall mean the Board of Directors of the Company, as constituted from time to time. 

(b) “Change in Control” shall mean: 

(i) The consummation of a merger or consolidation of the Company with or into another entity or any other corporate
reorganization, if persons who were not stockholders of the Company immediately prior to such merger, consolidation or other reorganization own immediately after such merger, consolidation or other reorganization 50% or more of the voting power of
the outstanding securities of each of (A) the continuing or surviving entity and (B) any direct or indirect parent corporation of such continuing or surviving entity; or 

(ii) The sale, transfer or other disposition of all or substantially all of the Company’s assets. 

  
 9

rights as a stockholder will exist with respect to the Shares, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is
