2012 Employee Stock Purchase Plan



 Exhibit 10.05 
 INFOBLOX INC. 
 2012 EMPLOYEE
STOCK PURCHASE PLAN 
 1. PURPOSE. Infoblox Inc. adopted the Plan
effective as of the date of the IPO. The purpose of this Plan is to provide eligible employees of the Company and the Participating Corporations with a means of acquiring an equity interest in the Company through payroll deductions, to enhance such
employees’ sense of participation in the affairs of the Company and the Participating Corporations, and to provide an incentive for continued employment. Capitalized terms not defined elsewhere in the text are defined in Section 27.

 2. ESTABLISHMENT OF PLAN. The Company proposes to grant rights to purchase shares of Common Stock to eligible
employees of the Company and its Participating Corporations pursuant to this Employee Stock Purchase Plan. The Company intends this Plan to qualify as an “employee stock purchase plan” under Section 423 of the Code (including any
amendments to or replacements of such Section), and this Plan shall be so construed. Any term not expressly defined in this Plan but defined for purposes of Section 423 of the Code shall have the same definition herein. However, with regard to
offers of options to purchase shares of the Common Stock under the Plan to employees outside the United States working for a Subsidiary or an affiliate of the Company that is not a Subsidiary, the Board may offer a subplan or an option that is not
intended to meet the Code Section 423 requirements, provided, if necessary under Section 423 of the Code, the other terms and conditions of the Plan are met. Subject to Section 14, a total of one million five hundred thousand
(1,500,000) shares of Common Stock is reserved for issuance under this Plan. In addition, on each January 1 for the first eight calendar years after the first Offering Date, the aggregate number of shares of Common Stock reserved for
issuance under the Plan shall be increased automatically by the number of shares equal to one (1%) of the total number of outstanding shares of the Common Stock on the immediately preceding December 31 (rounded down to the nearest whole
share), but not to exceed one million (1,000,000) shares; provided, that the Board or the Committee may in its sole discretion reduce the amount of the increase in any particular year. The number of shares reserved for issuance under
this Plan and the maximum number of shares that may be issued under this Plan shall be subject to adjustments effected in accordance with Section 14. 
 3. ADMINISTRATION. The Plan will be administered by the Committee. Subject to the provisions of this Plan and the limitations of Section 423 of the Code or any successor provision in
the Code, all questions of interpretation or application of this Plan shall be determined by the Committee and its decisions shall be final and binding upon all Participants. The Committee will have full and exclusive discretionary authority to
construe, interpret and apply the terms of the Plan, to determine eligibility and decide upon any and all claims filed under the Plan. Every finding, decision and determination made by the Committee will, to the full extent permitted by law, be
final and binding upon all parties. Notwithstanding any provision to the contrary in this Plan, the Committee may adopt rules and/or procedures relating to the operation and administration of the Plan to accommodate requirements of local law and
procedures outside of the United States. The Committee will have the authority to determine the Fair Market Value of the Common Stock (which determination shall be final, binding and conclusive for all purposes) in accordance with Section 8
below and to interpret Section 8 of the Plan in connection with circumstances that impact the Fair Market Value. Members of the Committee shall receive no compensation for their services in connection with the administration of this Plan, other
than standard fees as established from time to time by the Board for services rendered by Board members serving on Board committees. All expenses incurred in connection with the administration of this Plan shall be paid by the Company. For purposes
of this Plan, the Committee may designate separate offerings under the Plan (the terms of which need not be identical) in which eligible employees of one or more Participating 







 
Corporations will participate, even if the dates of the applicable Offering Periods of each such offering are identical. 
 4. ELIGIBILITY. 
 (a) Any employee of the Company or the
Participating Corporations is eligible to participate in an Offering Period under this Plan, except that one or more of the following categories of employees may be excluded from coverage under the Plan by the Committee (other than where prohibited
by applicable law): 
 (i) employees who are customarily employed for twenty (20) hours or less per week; 

(ii) employees who are customarily employed for five (5) months or less in a calendar year; and 

(iii) employees who do not meet any other eligibility requirements that the Committee may choose to impose (within the limits permitted
by the Code). 
 The foregoing notwithstanding, an individual shall not be eligible if his or her participation in the Plan is prohibited by the
law of any country that has jurisdiction over him or her or if he or she is subject to a collective bargaining agreement that does not provide for participation in the Plan. 
 (b) No employee who, together with any other person whose stock would be attributed to such employee pursuant to Section 424(d) of the Code, owns stock or holds options to purchase stock possessing
five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or its Parent or Subsidiary or who, as a result of being granted an option under this Plan with respect to such Offering Period, would
own stock or hold options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or its Parent or Subsidiary shall be granted an option to purchase Common Stock
under the Plan. 
 5. OFFERING DATES. 
 (a) Each Offering Period of this Plan may be of up to twenty-seven (27) months duration and shall commence and end at the times designated by the Committee. Each Offering Period may consist of one or
more Purchase Periods during which payroll deductions of Participants are accumulated under this Plan. 
 (b) The initial
Offering Period shall commence on the date on which the Registration Statement covering the IPO is declared effective by the U.S. Securities and Exchange Commission (the “Effective Date”), and shall end with the Purchase Date that occurs
on a date selected by the Committee which is approximately 24 months after the Effective Date (but in any event not more than 27 months after the Effective Date). The initial Offering Period shall consist of four Purchase Periods. Thereafter, a new
Offering Period shall commence every six (6) months thereafter, except as otherwise provided by an applicable subplan, or on such other date determined by the Committee. The Committee may at any time establish a different duration for an
Offering Period or Purchase Period to be effective after the next scheduled Purchase Date.

 6. PARTICIPATION IN THIS PLAN. 

(a) Any employee who is an eligible employee determined in accordance with Section 4 immediately prior to the initial Offering
Period will be automatically enrolled in the initial Offering Period under this Plan. With respect to subsequent Offering Periods, any eligible employee determined in accordance with Section 4 will be eligible to participate in this Plan,
subject to the requirement of Section 6(b) hereof and the other terms and provisions of this Plan. 
 (b) Notwithstanding
the foregoing, an eligible employee may elect to decrease the number of shares of Common Stock that such employee would otherwise be permitted to purchase for the initial Offering Period under the Plan and/or purchase shares of Common Stock for the
initial Offering Period through payroll deductions by delivering a subscription agreement to the Company within thirty (30) days after the filing of an effective registration statement pursuant to Form S-8. With respect to Offering Periods
after the initial Offering Period, a Participant may elect to participate in this Plan by submitting a subscription agreement prior to the commencement of the Offering Period (or such earlier date as the Committee may determine) to which such
agreement relates. 
 (c) Once an employee becomes a Participant in an Offering Period, then such Participant will automatically
participate in each subsequent Offering Period commencing immediately following the last day of the prior Offering Period unless the Participant withdraws or is deemed to withdraw from this Plan or terminates further participation in an Offering
Period as set forth in Section 11 below. Such Participant is not required to file any additional subscription agreement in order to continue participation in this Plan. 
 7. GRANT OF OPTION ON ENROLLMENT. Becoming a Participant with respect to an Offering Period will constitute the grant (as of the Offering Date) by the Company to such Participant of an
option to purchase on the Purchase Date up to that number of shares of Common Stock of the Company determined by a fraction, the numerator of which is the amount accumulated in such Participant’s payroll deduction account during such
Purchase Period and the denominator of which is the lower of (i) eighty-five percent (85%) of the Fair Market Value of a share of Common Stock on the Offering Date (but in no event less than the par value of a share of the Common
Stock), or (ii) eighty-five percent (85%) of the Fair Market Value of a share of the Common Stock on the Purchase Date (but in no event less than the par value of a share of the Common Stock) provided, however, that for the
Purchase Period within the initial Offering Period the numerator shall be fifteen percent (15%) of the Participant’s compensation for such Purchase Period, or such lower percentage as determined by the Committee prior to the Effective
Date, and provided, further, that the number of shares of Common Stock subject to any option granted pursuant to this Plan shall not exceed the lesser of (x) the maximum number of shares set by the Committee pursuant to
Section 10(b) below with respect to the applicable Purchase Date, or (y) the maximum number of shares which may be purchased pursuant to Section 10(a) below with respect to the applicable Purchase Date. 

8. PURCHASE PRICE. The Purchase Price per share at which a share of Common Stock will be sold in any Offering Period shall
be eighty-five percent (85%) of the lesser of: 
 (a) The Fair Market Value on the Offering Date; or 

(b) The Fair Market Value on the Purchase Date.

 9. PAYMENT OF PURCHASE PRICE; PAYROLL DEDUCTION CHANGES; SHARE ISSUANCES.

 (a) The Purchase Price shall be accumulated by regular payroll deductions made during each Offering Period, unless the
Committee determines with respect to categories of Participants outside the United States that contributions may be made in another form due to local legal requirements. The deductions are made as a percentage of the Participant’s compensation
in one percent (1%) increments not less than one percent (1%), nor greater than fifteen percent (15%) or such lower limit set by the Committee. Compensation shall mean all compensation, including, but not limited to base salary, wages,
commissions, overtime, shift premiums and regular bonuses, plus draws against commissions (or in foreign jurisdictions, equivalent cash compensation), but excluding amounts related to Company equity compensation; provided, however, that for purposes
of determining a Participant’s compensation, any election by such Participant to reduce his or her regular cash remuneration under Sections 125 or 401(k) of the Code (or in foreign jurisdictions, equivalent salary deductions) shall be
treated as if the Participant did not make such election. Payroll deductions shall commence on the first payday following the last Purchase Date (with respect to the initial Offering Period, first payday following the effective date of filing with
the U.S. Securities and Exchange Commission a securities registration statement for the Plan) and shall continue to the end of the Offering Period unless sooner altered or terminated as provided in this Plan. Notwithstanding the foregoing, the terms
of any subplan may permit matching shares without the payment of any purchase price. 
 (b) A Participant may increase or
decrease the rate of payroll deductions during a Purchase Period by filing with the Company a new authorization for payroll deductions, with the new rate to become effective no later than the second payroll period commencing after the Company’s
receipt of the authorization and continuing for the remainder of the Offering Period unless changed as described below. A change in the rate of payroll deductions may be made once during a Purchase Period or more frequently under rules determined by
the Committee. A Participant may increase or decrease the rate of payroll deductions for any subsequent Offering Period by filing with the Company a new authorization for payroll deductions prior to the beginning of such Offering Period, or such
other time period as specified by the Committee. 
 (c) A Participant may reduce his or her payroll deduction percentage to zero
during an Offering Period by filing with the Company a request for cessation of payroll deductions. Such reduction shall be effective beginning no later than the second payroll period after the Company’s receipt of the request and no further
payroll deductions will be made for the duration of the Offering Period. Payroll deductions credited to the Participant’s account prior to the effective date of the request shall be used to purchase shares of Common Stock in accordance with
Section (e) below. A reduction of the payroll deduction percentage to zero shall be treated as such Participant’s withdrawal from such Offering Period, and the Plan, effective as of the day after the next Purchase Date following the filing
date of such request with the Company. 
 (d) All payroll deductions made for a Participant are credited to his or her account
under this Plan and are deposited with the general funds of the Company, except to the extent required to be segregated due to local legal restrictions outside the United States. No interest accrues on the payroll deductions. All payroll deductions
received or held by the Company may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions, except to the extent necessary to comply with local legal requirements outside the
United States. 
 (e) On each Purchase Date, so long as this Plan remains in effect and provided that the Participant has not
submitted a signed and completed withdrawal form before that date which notifies 

  
 - 4 -









 
the Company that the Participant wishes to withdraw from that Offering Period under this Plan and have all payroll deductions accumulated in the account maintained on behalf of the Participant as
of that date returned to the Participant, the Company shall apply the funds then in the Participant’s account to the purchase of whole shares of Common Stock reserved under the option granted to such Participant with respect to the Offering
Period to the extent that such option is exercisable on the Purchase Date. The Purchase Price per share shall be as specified in Section 8 of this Plan. The Committee 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. Any amount remaining in a Participant’s account on a Purchase Date which is less than the amount
necessary to purchase a full share of Common Stock shall be returned to the Participant, without interest (except to the extent required due to local legal requirements outside the United States). In the event that this Plan has been oversubscribed,
all funds not used to purchase shares on the Purchase Date shall be returned to the Participant, without interest (except to the extent required due to local legal requirements outside the United States). No Common Stock shall be purchased on a
Purchase Date on behalf of any employee whose participation in this Plan has terminated prior to such Purchase Date. 
 (f) As
promptly as practicable after the Purchase Date, the Company shall issue shares for the Participant’s benefit representing the shares purchased upon exercise of his or her option. 

(g) During a Participant’s lifetime, his or her option to purchase shares hereunder is exercisable only by him or her. The
Participant will have no interest or voting right in shares covered by his or her option until such option has been exercised. 

(h) 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 Common Stock under the Plan until such obligations are satisfied. 

10. LIMITATIONS ON SHARES TO BE PURCHASED. 
 (a) Any other provision of the Plan notwithstanding, no Participant shall purchase Common Stock with a Fair Market Value in excess of the following limit: 

(i) In the case of Common Stock purchased during an Offering Period that commenced in the current calendar year, the limit
shall be equal to (A) $25,000 minus (B) the Fair Market Value of the Common Stock that the Participant previously purchased in the current calendar year (under this Plan and all other employee stock purchase plans of the Company or any
parent or Subsidiary of the Company). 
 (ii) In the case of Common Stock purchased during an Offering Period
that commenced in the immediately preceding calendar year, the limit shall be equal to (A) $50,000 minus (B) the Fair Market Value of the Common Stock that the Participant previously purchased (under this Plan and all other employee stock
purchase plans of the Company or any parent or Subsidiary of the Company) in the current calendar year and in the immediately preceding calendar year. 
 (iii) In the case of Common Stock purchased during an Offering Period that commenced in the second preceding calendar year, the limit shall be equal to (A) $75,000 minus (B) the Fair Market
Value of the Common Stock that the Participant previously purchased (under this Plan and all other employee stock purchase plans of the Company or any parent or Subsidiary of the Company) in the current calendar year and in the two preceding
calendar years. 

  
 - 5 -









 For purposes of this Subsection (a), the Fair Market Value of Common Stock shall be determined in each
case as of the beginning of the Offering Period in which such Common Stock is purchased. Employee stock purchase plans not described in section 423 of the Code shall be disregarded. If a Participant is precluded by this Subsection (a) from
purchasing additional Common Stock under the Plan, then his or her employee contributions shall automatically be discontinued and shall automatically resume at the beginning of the earliest Purchase Period that will end in the next calendar year (if
he or she then is an eligible employee), provided that when the Company automatically resumes such payroll deductions, the Company must apply the rate in effect immediately prior to such suspension. 

(b) In no event shall a Participant be permitted to purchase more than 5,000 Shares on any one Purchase Date or such lesser number as the
Committee shall determine. If a lower limit is set under this Subsection (b), then all Participants will be notified of such limit prior to the commencement of the next Offering Period for which it is to be effective. 

(c) If the number of shares to be purchased on a Purchase Date by all Participants exceeds the number of shares then available for
issuance under this Plan, then the Company will make a pro rata allocation of the remaining shares in as uniform a manner as shall be reasonably practicable and as the Committee shall determine to be equitable. In such event, the Company will give
notice of such reduction of the number of shares to be purchased under a Participant’s option to each Participant affected. 
 (d) Any payroll deductions accumulated in a Participant’s account which are not used to purchase stock due to the limitations in this Section 10, and not covered by Section 9(e), shall be
returned to the Participant as soon as practicable after the end of the applicable Purchase Period, without interest (except to the extent required due to local legal requirements outside the United States). 

11. WITHDRAWAL. 
 (a) Each Participant may withdraw from an Offering Period under this Plan pursuant to a method specified for such purpose by the Company. Such withdrawal may be elected at any time prior to the end of an
Offering Period, or such other time period as specified by the Committee. 
 (b) Upon withdrawal from this Plan, the accumulated
payroll deductions shall be returned to the withdrawn Participant, without interest, and his or her interest in this Plan shall terminate. In the event a Participant voluntarily elects to withdraw from this Plan, he or she may not resume his or her
participation in this Plan during the same Offering Period, but he or she may participate in any Offering Period under this Plan which commences on a date subsequent to such withdrawal by filing a new authorization for payroll deductions in the same
manner as set forth in Section 6 above for initial participation in this Plan. 
 (c) If the fair market value on the first
day of the current Offering Period in which a participant is enrolled is higher than the fair market value on the first day of any subsequent Offering Period, the Company will automatically enroll such participant in the subsequent Offering Period.

 12. TERMINATION OF EMPLOYMENT. Termination of a Participant’s employment for any reason, including
retirement, death, disability, or the failure of a Participant to remain an eligible employee of the Company or of a Participating Corporation, immediately terminates his or her participation in this Plan. In such event, accumulated payroll
deductions credited to the Participant’s account will be returned to him or her or, in the case of his or her death, to his or her legal representative, without interest (except to the extent required due to local legal requirements outside the
United States). For purposes of this Section 12, an employee will not be deemed to have terminated employment or failed 

  
 - 6 -









 
to remain in the continuous employ of the Company or of a Participating Corporation in the case of sick leave, military leave, or any other leave of absence approved by the Company;
provided that such leave is for a period of not more than ninety (90) days or reemployment upon the expiration of such leave is guaranteed by contract or statute. The Company will have sole discretion to determine whether a Participant
has terminated employment and the effective date on which the Participant terminated employment, regardless of any notice period or garden leave required under local law. 
 13. RETURN OF PAYROLL DEDUCTIONS. In the event a Participant’s interest in this Plan is terminated by withdrawal, termination of employment or otherwise, or in the event this Plan is
terminated by the Board, the Company shall deliver to the Participant all accumulated payroll deductions credited to such Participant’s account. No interest shall accrue on the payroll deductions of a Participant in this Plan (except to the
extent required due to local legal requirements outside the United States). 
 14. CAPITAL CHANGES. If the number
of outstanding Shares is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company, without consideration, then the Committee
shall adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised, and the numerical
limits of Sections 1 and 10 shall be proportionately adjusted, subject to any required action by the Board or the stockholders of the Company and in compliance with applicable securities laws; provided that fractions of a Share will not be issued.

 15. NONASSIGNABILITY. Neither payroll deductions credited to a Participant’s account nor any rights with
regard to the exercise of an option or to receive shares under this Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 22 below) by
the Participant. Any such attempt at assignment, transfer, pledge or other disposition shall be void and without effect. 

16. USE OF PARTICIPANT FUNDS AND REPORTS. The Company may use all payroll deductions received or held by it under the Plan
for any corporate purpose, and the Company will not be required to segregate Participant payroll deductions (except to the extent required due to local legal requirements outside the United States). Until Shares are issued, Participants will only
have the rights of an unsecured creditor. Each Participant shall receive promptly after the end of each Purchase Period a report of his or her account setting forth the total payroll deductions accumulated, the number of shares purchased, the per
share price thereof and the remaining cash balance, if any, carried forward to the next Purchase Period or Offering Period, as the case may be. 
 17. NOTICE OF DISPOSITION. Each U.S. taxpayer Participant shall notify the Company in writing if the Participant disposes of any of the shares purchased in any Offering Period pursuant to
this Plan if such disposition occurs within two (2) years from the Offering Date or within one (1) year from the Purchase Date on which such shares were purchased (the “Notice Period”). The Company may, at any time during
the Notice Period, place a legend or legends on any certificate representing shares acquired pursuant to this Plan requesting the Company’s transfer agent to notify the Company of any transfer of the shares. The obligation of the Participant to
provide such notice shall continue notwithstanding the placement of any such legend on the certificates. 
 18. NO
RIGHTS TO CONTINUED EMPLOYMENT. Neither this Plan nor the grant of any option hereunder shall confer any right on any employee to remain in the employ of the Company or any Participating Corporation, or restrict the right of the Company or any
Participating Corporation to terminate such employee’s employment.

 19. EQUAL RIGHTS AND PRIVILEGES. All eligible employees granted an option
under this Plan that is intended to meet the Code Section 423 requirements shall have equal rights and privileges with respect to this Plan or within any separate offering under the Plan so that this Plan qualifies as an “employee stock
purchase plan” within the meaning of Section 423 or any successor provision of the Code and the related regulations. Any provision of this Plan which is inconsistent with Section 423 or any successor provision of the Code shall,
without further act or amendment by the Company, the Committee or the Board, be reformed to comply with the requirements of Section 423. This Section 19 shall take precedence over all other provisions in this Plan. 

20. NOTICES. All notices or other communications by a Participant to the Company under or in connection with this Plan
shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

21. TERM; STOCKHOLDER APPROVAL. This Plan will become effective on the Effective Date. This Plan shall be approved by the
stockholders of the Company, in any manner permitted by applicable corporate law, within twelve (12) months before or after the date this Plan is adopted by the Board. No purchase of shares that are subject to such stockholder approval before
becoming available under this Plan shall occur prior to stockholder approval of such shares and the Board or Committee may delay any Purchase Date and postpone the commencement of any Offering Period subsequent to such Purchase Date as deemed
necessary or desirable to obtain such approval (provided that if a Purchase Date would occur more than twenty-four (24) months after commencement of the Offering Period to which it relates, then such Purchase Date shall not occur and instead
such Offering Period shall terminate without the purchase of such shares and Participants in such Offering Period shall be refunded their contributions without interest). This Plan shall continue until the earlier to occur of (a) termination of
this Plan by the Board (which termination may be effected by the Board at any time pursuant to Section 25 below), (b) issuance of all of the shares of Common Stock reserved for issuance under this Plan, or (c) the tenth anniversary of
the first Purchase Date under the Plan. 
 22. DESIGNATION OF BENEFICIARY. 

(a) A Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s account under
this Plan in the event of such Participant’s death prior to a Purchase Date. Such form shall be valid only if it was filed with the Company at the prescribed location before the Participant’s death. 

(b) Such designation of beneficiary may be changed by the Participant at any time by written notice filed with the Company at the
prescribed location before the Participant’s death. In the event of the death of a Participant and in the absence of a beneficiary validly designated under this Plan who is living at the time of such Participant’s death, the Company shall
deliver such cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares or cash to the
spouse or, if no spouse is known to the Company, then to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

23. CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE OF SHARES. Shares shall not be issued with respect to an option
unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act, the Securities Exchange Act
of 1934, as amended, the rules and regulations promulgated thereunder, and the requirements of any stock 

  
 - 8 -









 
exchange or automated quotation system upon which the shares may then be listed, exchange control restrictions and/or securities law restrictions outside the United States, and shall be further
subject to the approval of counsel for the Company with respect to such compliance. Shares may be held in trust or subject to further restrictions as permitted by any suplan. 
 24. APPLICABLE LAW. The Plan shall be governed by the substantive laws (excluding the conflict of laws rules) of the State of Delaware. 

25. AMENDMENT OR TERMINATION. The Committee, 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 Committee, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next
Purchase Date (which may be sooner than originally scheduled, if determined by the Committee in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to
Section 14). If an Offering Period is terminated prior to its previously-scheduled expiration, all amounts then credited to Participants’ accounts for such Offering Period, which have not been used to purchase shares of Common Stock, shall
be returned to those Participants (without interest thereon, except as otherwise required under local laws) as soon as administratively practicable. Further, the Committee will be entitled to change the Purchase Periods and 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 administration of the Plan, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common
Stock for each Participant properly correspond with amounts withheld from the Participant’s base salary or regular hourly wages, and establish such other limitations or procedures as the Committee determines in its sole discretion advisable
which are consistent with the Plan. Such actions will not require stockholder approval or the consent of any Participants. However, no amendment shall be made without approval of the stockholders of the Company (obtained in accordance with
Section 21 above) within twelve (12) months of the adoption of such amendment (or earlier if required by Section 21) if such amendment would: (a) increase the number of shares that may be issued under this Plan; or
(b) change the designation of the employees (or class of employees) eligible for participation in this Plan. 
 26.
CORPORATE TRANSACTIONS. In the event of a Corporate Transaction, each outstanding right to purchase Common Stock will be assumed or an equivalent option substituted by the successor corporation or a parent or a subsidiary of the successor
corporation. In the event that the successor corporation refuses to assume or substitute for the purchase right, the Offering Period with respect to which such purchase right relates will be shortened by setting a new Purchase Date and will end on
the new Purchase Date. The new Purchase Date shall occur on or prior to the consummation of the Corporate Transaction, and the Plan shall terminate on the consummation of the Corporate Transaction.
