EXHIBIT A
STOCK OPTION AGREEMENT

Type of Option

The type of option which you have been granted is designated on the cover sheet.  If designated as an Incentive Stock Option, the Option is intended to be an incentive stock option under section 422 of the United States Internal Revenue Code (the "Code") and will be interpreted accordingly. 

Capitalized terms used but not otherwise defined in this Stock Option Agreement shall have the meanings given to them in the Plan.

Vesting

You may exercise the Option during its term in accordance with the exercise schedule set out in the cover sheet and the applicable provisions of the Plan and this Stock Option Agreement.  In the event of your death, Disability or other termination of status as a Service Provider, the exercisability of the option is governed by the applicable provisions of the Plan and this Stock Option Agreement.

Early Exercise with Restricted Stock Purchase Agreement

Notwithstanding the vesting schedule described in the coversheet or the provisions of the foregoing paragraph, you may exercise this Option during its term at any time as to shares that have not vested (the "Unvested Shares"), provided that at the time of such exercise you deliver to the Company, in addition to the other exercise documentation required hereby, an executed copy of the Restricted Stock Purchase Agreement attached as Exhibit D, along with its attachments, as applicable (the "Restricted Stock Agreement"), whereby, among other things, you agree to grant to the Company certain repurchase rights, at cost, with respect to the Unvested Shares, as more fully set forth therein, which repurchase rights shall lapse over time with respect to the Unvested Shares in accordance with the vesting schedule set forth on the coversheet (an "Early Exercise with Repurchase Agreement").  

Term
    
The Option may be exercised only within the term set out in the cover sheet, and may be exercised during such term only in accordance with the Plan and this Stock Option Agreement.  Notwithstanding any post-termination exercise period set forth in this Stock Option Agreement, the Option will expire on the Expiration Date shown on the cover sheet, which is the day before the 10th anniversary of the Date of Grant.  It may expire earlier if your status as a Service Provider terminates, as described below.

Regular Termination

In the event of the termination of your status as a Service Provider for any reason other than death or Disability, you may, to the extent otherwise so entitled at the date of such termination, exercise the Option within 90 days after your termination.  To the extent that you were not entitled to exercise the Option at the date of such termination, or if you do not exercise the Option within the 90-day period specified above, the Option will terminate.

Death

If your status as Service Provider terminates because of your death, the Option may be exercised at any time within twelve (12) months following the date of death by your estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent that the Option was exercisable as of the date of your death. 

A-1

Disability

If your status as Service Provider terminates because of your Disability, you may, but only within six (6) months from the date of such termination, exercise the Option to the extent  that the Option was exercisable as of the date of such termination.  

Status as Service Provider

For purposes of the Option, your status as a Service Provider will be considered terminated for purposes of vesting and any post-termination exercise period as of the date you are no longer actively providing services to the Company or a Parent or Subsidiary (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any) and will not be extended by any notice period (e.g., your period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any); the Administrator shall have the exclusive discretion to determine when you are no longer actively providing services for purposes of the Option (including whether you may still be considered to be providing services while on a leave of absence).

Further, no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from the termination of your status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any), and in consideration of the grant of the Option to which you are otherwise not entitled, you irrevocably agree never to institute any claim against the Company or any Parent or Subsidiary, waive your ability, if any, to bring any such claim, and release the Company and any Parent or Subsidiary from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, you shall be deemed irrevocably to have agreed not to pursue such claim and agree to execute any and all documents necessary to request dismissal or withdrawal of such claim.

Restrictions on Exercise

The Company will not permit you to exercise the Option if the issuance of Shares at that time would violate any applicable law or regulation.  Further, notwithstanding any other provision of the Plan or this Stock Option Agreement, unless there is an available exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon exercise of the Option prior to the completion of any registration or qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the United States Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable.  You understand that the Company is under no obligation to register or qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of the shares.  Further, you agree that the Company shall have unilateral authority to amend the Plan and this Stock Option Agreement without your consent to the extent necessary to comply with securities or other laws applicable to issuance of Shares.

Notice of Exercise

When you wish to exercise the Option, you must notify the Company by filing the proper "Notice of Exercise" form (attached hereto as Exhibit C) at the address given on the form.  Your notice must specify how many Shares you wish to purchase.  The notice will be effective when it is received by the Company.  If someone else wants to exercise the Option after your death, that person must prove to the Company's satisfaction that he or she is entitled to do so. In the event of an Early Exercise with Repurchase Agreement, you must also execute and deliver the Restricted Stock Purchase Agreement in the form attached hereto as Exhibit D, along with Exhibits D-2, D-3 and D-4.  

A-2

Form of Payment

Your Notice of Exercise must be accompanied by payment of the aggregate purchase price plus any applicable Tax-Related Items (as defined below) as to all Shares you wish to purchase.  Payment of the purchase price and any applicable Tax-Related Items shall be by cash or personal check.  

Tax Withholding

You acknowledge that, regardless of any action taken by the Company or, if different, your employer (the “Employer”) the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax‐related items related to your participation in the Plan and legally applicable to you (“Tax-Related Items”), is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer.  You further acknowledge that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, including, but not limited to, the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result.  

Prior to the relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items.  If you fail to make satisfactory arrangements for the payment of any required Tax-Related Items hereunder at the time of the Option exercise, you acknowledge and agree that the Company may refuse to honor the exercise and refuse to deliver the Shares if such amounts are not delivered at the time of exercise together with the purchase price.
To the extent determined appropriate by the Company in its discretion, the Company shall have the right (but not the obligation) to satisfy any Tax-Related Items by withholding from any cash compensation due to you and/or reducing the number of Shares otherwise deliverable to you upon exercise of the Option.  Further, if you are subject to Tax-Related Items in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, you acknowledge that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.
No Advice Regarding Participation

The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding your participation in the Plan, the exercise of the Option or the sale of any Shares acquired upon exercise of the Option.  You are hereby advised to consult with your own personal tax, legal and financial advisors regarding your participation in the Plan before taking any action related to the Plan.

Representations

If the Shares you intend to purchase have not been registered under the United States Securities Act of 1933, as amended, at the time the Option is exercised, the Company may require you to (i) deliver to the Company your Investment Representation Statement (attached as Exhibit B), which may contain, among other things, an agreement to refrain from sales of the Shares for up to 180 days immediately following an underwritten initial public offering, and (ii) read the applicable rules of the Commissioner of Corporations of California attached to such Investment Representation Statement, if applicable.

Right of First Refusal

In the event that you propose to sell, pledge or otherwise transfer to a third party any Shares acquired under this Stock Option Agreement, or any interest in such Shares, the Company shall have the "Right of First Refusal" with respect to all (and not less than all) of such Shares.  If you desire to transfer any Shares acquired under this Stock Option Agreement, you must give a written notice to the Company describing fully the proposed transfer, including the number of Shares proposed to be transferred, the proposed transfer price and the name and address of the proposed transferee.  The 

A-3

Company shall have the right to purchase all, and not less than all, of the Shares on the terms of the proposal described in the notice by delivery of a notice of exercise of the Right of First Refusal within 30 days after the date when the notice was received by the Company.

If the Company fails to exercise its Right of First Refusal within 30 days after the date when it received the notice, you may, not later than three (3) months following receipt of the notice by the Company, conclude a transfer of the Shares on the terms and conditions described in the notice.  If the Company exercises its Right of First Refusal, the parties shall consummate the sale of the Shares within 30 days after the date when the Company received the notice. The Company's Right of First Refusal shall terminate in the event that Stock is listed on an established stock exchange or is quoted regularly on the Nasdaq National Market.

Transfer of Option

Prior to your death, only you may exercise the Option.  You cannot transfer or assign the Option.  For instance, you may not sell the Option or use it as security for a loan.  If you attempt to transfer or assign the Option, the Option will immediately become invalid.  You may, however, dispose of the Option in your will.

Regardless of any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your spouse or former spouse, nor is the Company obligated to recognize such individual's interest in the Option in any other way.

No Employment Rights

Neither the Option grant, this Stock Option Agreement or your participation in the Plan shall create a right to employment or be interpreted as forming an employment or service contract with the Company, the Employer or any Parent or Subsidiary, and shall not interfere with the ability of the Company, the Employer or any Parent or Subsidiary, as applicable, to terminate your employment or service relationship (if any) at any time and for any reason.
Nature of Grant

In accepting the Option, you acknowledge, understand and agree that: (1) the Plan is established voluntarily by the Company, it is discretionary in nature, and may be amended, suspended or terminated by the Company at any time to the extent permitted by the Plan; (2) the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past; (3) all decisions with respect to future option or other grants, if any, will be at the sole discretion of the Company; (4) you are voluntarily participating in the Plan; (5) the Option and any Shares acquired under the Plan are not intended to replace any pension rights or compensation; (5) the Option and any Shares acquired under the Plan and the income and value of same, are not part of normal or expected compensation for any purpose; (6) the future value of the Shares underlying the Option is unknown, indeterminable, and cannot be predicted with certainty; (7) if the underlying Shares do not increase in value, the Option will have no value; (8) if you exercise the Option and acquire Shares, the value of such Shares may increase or decrease in value, even below the exercise price; (9) unless otherwise provided in the Plan or this Stock Option Agreement, or by the Company in its discretion, the Option and the benefits evidenced by this Stock Option Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares of the Company; and (10) neither the Company, the Employer nor any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation between your local currency and the United States Dollar that may affect the value of the Option or of any amounts due to you pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon exercise.
Shareholder Rights

Neither you, your estate nor your heirs, shall have any rights as a shareholder of the Company until a certificate for your option Shares has been issued.  No adjustments are made for dividends or other rights if the applicable record date occurs before your stock certificate is issued, except as described in the Plan.

A-4

Adjustments

In the event of a stock split, a stock dividend or a similar change in the Company stock, the number of Shares covered by the Option and the exercise price per share may be adjusted pursuant to the Plan.  In the event of the proposed dissolution or liquidation of the Company, or of a merger in which the successor corporation does not agree to assume the Option or substitute an equivalent option, the Board shall notify you at least thirty (30) days prior to such proposed action.  To the extent it has not been previously exercised, the Option will terminate immediately prior to the consummation of such proposed action. 

Legends

All certificates representing the Shares issued upon exercise of this Option shall, where applicable, have endorsed thereon the following legends:

"THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND OPTIONS TO PURCHASE SUCH SHARES SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR HIS OR HER PREDECESSOR IN INTEREST.  A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY AND WILL BE FURNISHED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY BY THE HOLDER OF RECORD OF THE SHARES REPRESENTED BY THIS CERTIFICATE."

"THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED."

Governing Law; Venue

This Stock Option Agreement will be interpreted and enforced under the laws of the State of California without regard to its conflict of law provisions.  For purposes of any action, lawsuit or other proceedings brought to enforce this Stock Option Agreement, relating to it, or arising from it, the parties hereby submit to and consent to the sole and exclusive jurisdiction of the courts of Santa Clara, California or the federal courts for the United States for the Northern District of California, and no other courts, where this grant is made and/or to be performed.

You understand that the Company and the Employer may hold certain personal information about you, including, but not limited to, your name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, and details of all options or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in your favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan.   

You understand that Data may be transferred to a broker or stock plan service provider selected by the Company either now or in the future for purposes of assisting the Company with the implementation, administration and management of the Plan.  You understand that the recipients of the Data may be located in the United States or elsewhere, and that the recipient’s country (e.g., the United States) may have different data privacy laws and protections than your country.

Therefore, you understand that refusing or withdrawing your consent may affect your ability to participate in the Plan.  For more information on the consequences of your refusal to consent or withdrawal of consent, you understand that you may contact your local human resources representative.

Imposition of Other Requirements  
The Company reserves the right to impose other requirements on your participation in the Plan, on the Option and on any Shares purchased upon exercise of the Option, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require you to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.
Waiver

	OPTIONEE

	AMOUNT:
	 
	 

	DATE:
	 
	 

In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the following:

(a)    Optionee is aware of the Company's business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the securities.  Optionee is acquiring these securities for investment for Optionee's own account only and not with a view to, or for resale in connection with, any "distribution" thereof within the meaning of the United States Securities Act of 1933, as amended (the "Securities Act").

(b)    Optionee acknowledges and understands that the securities constitute "restricted securities" under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee's investment intent as expressed herein.  In this connection, Optionee understands that, in the view of the United States Securities and Exchange Commission (the “SEC”), the statutory basis for such exemption may be unavailable if Optionee's representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future.  Optionee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available.  Optionee further acknowledges and understands that the Company is under no obligation to register the securities.  Optionee understands that the certificate evidencing the securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company, a legend prohibiting their transfer without the consent of the Commissioner of Corporations of the State of California and any other legend required under applicable state securities laws.

(c)    Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of "restricted securities" acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions.  Rule 701 provides that if the issuer qualifies under Rule 701 at the time of exercise of the Option by the Optionee, such exercise will be exempt from registration under the Securities Act.  In the event the Company later becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”), ninety (90) days thereafter the securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including among other things:  (1) the sale being made through a broker in an unsolicited "broker's transaction" or in transactions directly with a market maker (as said term is defined under the Exchange Act); and, in the case of an affiliate, (2) the availability of certain public information about the Company, and the amount of securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), if applicable.  

In the event that the Company does not qualify under Rule 701 at the time of exercise of the Option, then the securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires among 

B-1

other things:  (1) the resale occurring not less than one year after the party has purchased, and made full payment for, within the meaning of Rule 144, the securities to be sold; and, in the case of an affiliate, or of a non-affiliate who has held the securities less than two years, (2) the availability of certain public information about the Company, (3) the sale being made through a broker in an unsolicited "broker's transaction" or in transactions directly with a market maker (as said term is defined under the Exchange Act), and (4) the amount of securities being sold during any three month period not exceeding the specified limitations stated therein, if applicable.

(d)  Optionee agrees, in connection with the Company's initial underwritten public offering of the Company's securities, (1) not to sell, make short sale of, loan, grant any options for the purchase of, or otherwise dispose of any shares of Common Stock of the Company held by Optionee (other than those shares included in the registration) without the prior written consent of the Company or the underwriters managing such initial underwritten public offering of the Company's securities for one hundred eighty (180) days from the effective date of such registration, and (2) further agrees to execute any agreement reflecting (1) above as may be requested by the underwriters at the time of the public offering; provided however that the officers and directors of the Company who own stock in the Company also agree to such restrictions.

(e)    Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A of the Securities Act, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the SEC has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.  Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

(f)    Optionee understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities without the consent of the Commissioner of Corporations of California.  Optionee has read the applicable Commissioner's Rules with respect to such restriction, a copy of which is attached.

EXHIBIT D

A10 NETWORKS, INC.
2008 Stock Plan
RESTRICTED STOCK PURCHASE AGREEMENT

THIS AGREEMENT is made between «First» «Last» (the "Purchaser") and A10 Networks, Inc., a California corporation (the "Company") as of __________________, 20__.

RECITALS

(1)    Pursuant to the exercise of the stock option (grant number «Grant_No») granted to Purchaser under the Company's 2008 Stock Plan (the "Plan") and pursuant to the Stock Option Agreement (the "Option Agreement") dated «Grant_Date» by and between the Company and Purchaser with respect to such grant, which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase _________ of those shares which have not become vested under the vesting schedule set forth in the Option Agreement (the "Unvested Shares").  The Unvested Shares and the shares subject to the Option Agreement which have become vested are sometimes collectively referred to herein as the "Shares". 

(2)    As a condition to Purchaser's election to exercise the Option as to the Unvested Shares, Purchase hereby  executes and delivers this Restricted Stock Purchase Agreement, which sets forth certain rights and obligations of the parties with respect to the Unvested Shares acquired upon exercise of the Option.

1.    Repurchase Option.

(a)    If Purchaser's status as an Employee, Consultant or director, as applicable, is terminated for any or no reason, including for cause or without cause, death or disability, the Company shall have the right and option to purchase from Purchaser, or Purchaser's personal representative, as the case may be, all or any portion of the Purchaser’s Then-Unvested Shares (as defined below) as of the date of such termination at the original exercise price paid by the Purchaser for such Shares (the "Repurchase Option"), which repurchase price may be paid in cash, by cancellation of indebtedness under the Note, or a combination.  The term "Then-Unvested Shares" as used herein shall mean that portion of the Unvested Shares that remain unvested on such termination date in accordance with the vesting provisions set forth in the Option Agreement.

(b)    Upon the occurrence of a termination, the Company may exercise its Repurchase Option by delivering personally or by registered mail, to Purchaser (or his transferee or legal representative, as the case may be), within ninety (90) days of the termination, a notice in writing indicating the Company's intention to exercise the Repurchase Option and setting forth a date for closing not later than thirty (30) days from the mailing of such notice. The closing shall take place at the Company's office.  At the closing, the holder of the certificates for the Then-Unvested Shares being transferred shall deliver the stock certificate or certificates evidencing the Then-Unvested Shares, and the Company shall deliver the purchase price therefor.

(c)    At its option, the Company may elect to make payment for the Then-Unvested Shares to a bank selected by the Company.  The Company shall avail itself of this option by a notice in writing to Purchaser stating the name and address of the bank, date of closing, and waiving the closing at the Company's office.

(d)    If the Company does not elect to exercise the Repurchase Option conferred above by giving the requisite notice within ninety (90) days following the termination, the Repurchase Option shall terminate.

(e)    The Repurchase Option shall terminate in accordance with the vesting schedule in Optionee's Option Agreement.

2.    Transferability of the Shares; Escrow.

(a)    Purchaser hereby authorizes and directs the secretary of the Company, or such other person designated by the Company, to transfer the Then-Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company.

(b)    To insure the availability for delivery of Purchaser's Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the secretary, or any other person designated by the Company as escrow agent, as its attorney-in-fact to sell, assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon execution of this Agreement, deliver and deposit with the secretary of the Company, or such other person designated by the Company, the share certificates representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit D-2.  The Unvested Shares and stock assignment shall be held by the secretary in escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit D-3 hereto, until the Company exercises its purchase right as provided in Section 1, until such Unvested Shares are vested, or until such time as this Agreement no longer is in effect.  As a further condition to the Company's obligations under this Agreement, the spouse of the Purchaser, if any, shall execute and deliver to the Company the Consent of Spouse attached hereto as Exhibit D-4.  Upon vesting of the Unvested Shares (and, if applicable, the Note is paid in full), the escrow agent shall promptly upon written request, or periodically without written request, deliver to the Purchaser the certificate or certificates representing such Shares in the escrow agent's possession belonging to the Purchaser, and the escrow agent shall be discharged of all further obligations hereunder; provided, however, that the escrow agent shall nevertheless retain such certificate or certificates as escrow agent if so required pursuant to other restrictions imposed pursuant to this Agreement.

(c)    The Company, or its designee, shall not be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment.

(d)     Purchaser shall not sell, transfer, pledge, hypothecate or otherwise dispose of any of the Unvested Shares which remain subject to the Company’s Repurchase Option. Notwithstanding the foregoing, upon prior written consent of the Company (which consent shall not be unreasonably withheld), the Purchaser may assign or transfer Unvested Shares for family planning, tax planning or estate planning, or other such purposes, provided the transferee agrees to be bound by all obligations of the Purchaser, and the Company is reasonably secure that such obligations remain enforceable against the transferee.  

(e)    Transfer or sale of the Shares is subject to restrictions on transfer imposed by any applicable state and federal securities laws.  Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with respect to any Unvested Shares purchased by Purchaser and shall acknowledge the same by signing a copy of this Agreement.

3.    Ownership, Voting Rights, Duties.  This Agreement shall not affect in any way the ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein. 

4.    Legends.  The share certificate evidencing the Shares issued hereunder may be endorsed with the legend substantially to the following effect (in addition to any legend required under applicable state securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

5.    Adjustment for Stock Split.  All references to the number of Shares and the purchase price of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares which may be made by the Company after the date of this Agreement.

2

6.    Notices.  Notices required hereunder shall be given in person or by registered mail to the address of Purchaser shown on the records of the Company, and to the Company at their respective principal executive offices.

7.    Survival of Terms.  This Agreement shall apply to and bind Purchaser and the Company and their respective permitted assignees and transferees, heirs, legatees, executors, administrators and legal successors.

8.    Section 83(b) Election.  Purchaser hereby acknowledges that he or she has been informed that, with respect to the exercise of an Option for unvested Shares, an election may be filed by the Purchaser with the Internal Revenue Service, within 30 days of the purchase of the Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the Shares and their Fair Market Value on the date of purchase.  In the case of a Nonstatutory Stock Option, this will result in a recognition of taxable income to the Purchaser on the date of exercise, measured by the excess, if any, of the fair market value of the Shares, at the time the Option is exercised over the purchase price for the Shares.  Absent such an election, taxable income will be measured and recognized by Purchaser at the time or times on which the Company's Repurchase Option lapses.  In the case of an Incentive Stock Option, such an election will result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the fair market value of the Shares, at the time the option is exercised, over the purchase price for the Shares.  Absent such an election, alternative minimum taxable income will be measured and recognized by Purchaser at the time or times on which the Company's Repurchase Option lapses.   Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code.  A form of Election under Section 83(b) is attached hereto as Exhibit D-5 for reference.  

PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S SOLE RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER'S BEHALF.

9    Standoff Agreement.  Purchaser agrees, in connection with the Company's initial public offering of its equity securities, and upon request of the Company or the underwriters managing such offering, not to sell, make any short sale of, loan, grant any option for the purchase of or otherwise dispose of any shares of Stock (other than those included in the registration, if any) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty (180) days) from the effective date of such registration as may be requested by the Company or such underwriters; provided, that the officers and directors of the Company who own stock of the Company also agree to such restrictions.

10.     Representations.  Purchaser has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement.  Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents.  Purchaser understands that he (and not the Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

11.      Governing Law.  This Agreement shall be governed by the internal substantive laws, but not the choice of law rules, of California.

Purchaser represents that he has read this Agreement and is familiar with its terms and provisions.  Purchaser hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement.

Dear Secretary:

As Escrow Agent for both A10 Networks, Inc. (the "Company"), and the undersigned purchaser of stock of the Company (the "Purchaser"), you are hereby authorized and directed to hold the documents delivered to you pursuant to the terms of that certain Restricted Stock Purchase Agreement ("Agreement") between the Company and the undersigned, in accordance with the following instructions:

1.    In the event the Company and/or any assignee of the Company (referred to collectively for convenience herein as the "Company") exercises the Company's repurchase option set forth in the Agreement, the Company shall give to Purchaser and you a written notice specifying the number of shares of stock to be purchased, the purchase price, and the time for a closing hereunder at the principal office of the Company.  Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice.

2.    At the closing, you are directed (a) to date the stock assignments necessary for the transfer in question, (b) to fill in the number of shares being transferred, and (c) to deliver same, together with the certificate evidencing the shares of stock to be transferred, to the Company or its assignee, against the simultaneous delivery to you of the purchase price (by cash, a check, cancellation of indebtedness, if applicable, or some combination thereof) for the number of shares of stock being purchased pursuant to the exercise of the Company's repurchase option.

3.    Purchaser irrevocably authorizes the Company to deposit with you any certificates evidencing shares of stock to be held by you hereunder and any additions and substitutions to said shares as defined in the Agreement.  Purchaser does hereby irrevocably constitute and appoint you as Purchaser's attorney-in-fact and agent for the term of this escrow to execute with respect to such securities all documents necessary or appropriate to make such securities negotiable and to complete any transaction herein contemplated, including but not limited to the filing with any applicable state blue sky authority of any required applications for consent to, or notice of transfer of, the securities.  Subject to the provisions of this paragraph 3, Purchaser shall exercise all rights and privileges of a stockholder of the Company while the stock is held by you.

4.    Upon written request of the Purchaser, but no more than once per calendar year, unless the Company's repurchase option has been exercised, you will deliver to Purchaser a certificate or certificates representing so many shares of stock as are not then subject to the Company's repurchase option.  Within 120 days after cessation of Purchaser's continuous employment by or services to the Company, or any parent or subsidiary of the Company, you will deliver to Purchaser a certificate or certificates representing the aggregate number of shares held or issued pursuant to the Agreement and not purchased by the Company or its assignees pursuant to exercise of the Company's repurchase option.  

5     If at the time of termination of this escrow you should have in your possession any documents, securities, or other property belonging to Purchaser, you shall deliver all of the same to Purchaser and shall be discharged of all further obligations hereunder.

6     Your duties hereunder may be altered, amended, modified or revoked only by a writing signed by all of the parties hereto.

7     You shall be obligated only for the performance of such duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by you to be 

genuine and to have been signed or presented by the proper party or parties.  You shall not be personally liable for any act you may do or omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith, and any act done or omitted by you pursuant to the advice of your own attorneys shall be conclusive evidence of such good faith.

8     You are hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person or corporation, excepting only orders or process of courts of law and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court.  In case you obey or comply with any such order, judgment or decree, you shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

9     You shall not be liable in any respect on account of the identity, authorities or rights of the parties executing or delivering or purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder.

10     You shall not be liable for the outlawing of any rights under the Statute of Limitations with respect to these Joint Escrow Instructions or any documents deposited with you.
11     You shall be entitled to employ such legal counsel and other experts as you may deem necessary properly to advise you in connection with your obligations hereunder, may rely upon the advice of such counsel, and may pay such counsel reasonable compensation therefor.

12     Your responsibilities as Escrow Agent hereunder shall terminate if you shall cease to be an officer or agent of the Company or if you shall resign by written notice to each the Company.  In the event of any such termination, the Company shall have the right, in its sole discretion, to appoint a successor Escrow Agent.

13     If you reasonably require other or further instruments in connection with these Joint Escrow Instructions or obligations in respect hereto, the necessary parties hereto shall join in furnishing such instruments.

14     It is understood and agreed that should any dispute arise with respect to the delivery and/or ownership or right of possession of the securities held by you hereunder, you are authorized and directed to retain in your possession without liability to anyone all or any part of said securities until such disputes shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction after the time for appeal has expired and no appeal has been perfected, but you shall be under no duty whatsoever to institute or defend any such proceedings.

15     Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States Post Office, by registered or certified mail with postage and fees prepaid, addressed to each of the other parties thereunto entitled at the following addresses or at such other addresses as a party may designate by ten days' advance written notice to each of the other parties hereto.

The Company hereby grants to the individual named in the Notice of Grant (“Participant”) an option (the “Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), subject to all of the terms and conditions in this Stock Option Agreement, including the Notice of Grant, these Terms and Conditions of Stock Option Grant (the “Option Terms”), the Appendix to the Stock Option Agreement attached hereto as Exhibit B (the “Appendix”) and any other exhibits attached hereto (the Notice of Grant, the Option Terms, the Appendix and any other exhibits attached hereto are referred to collectively herein as the “Award Agreement”), and the Plan, which is incorporated herein by reference.  Subject to Section 19(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of the Award Agreement, the terms and conditions of the Plan will prevail.
(a)If Participant is a United States (“U.S.”) taxpayer, the Option will be designated as either an Incentive Stock Option (“ISO”) or a Nonstatutory Stock Option (“NSO”).  If designated in the Notice of Grant as an ISO, the Option is intended to qualify as an ISO under Section 422 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”).  However, if the Option is intended to be an ISO, to the extent that it exceeds the $100,000 rule of Code Section 422(d), it will be treated as an NSO.  Further, if for any reason the Option (or portion thereof) will not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan.  In no event will the Administrator, the Company or any Parent or Subsidiary of the Company, or any of their respective employees or directors, have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO.  
(a)    If Participant is a non-U.S. taxpayer, the Option will be designated as an NSO.
2.    Vesting Schedule.  
(a)    Except as provided in this Section 2 or Section 3, the Option awarded by the Award Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant.  Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the provisions of the Award Agreement, unless Participant will have been continuously a Service Provider (as described in Section 2(b) below) from the Date of Grant until the date such vesting occurs.
(b)    For purposes of the Option, Participant’s status as a Service Provider will be considered terminated as of the date that Participant is no longer actively providing services to the Company or any Parent or Subsidiary of the Company (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or providing services, or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in the Award Agreement or determined by the Administrator, Participant’s right to vest in the Option under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or providing services, or the terms of Participant’s employment or service agreement, if any).  The Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the Option (including whether Participant may still be considered to be providing services while on a leave of absence).
3.    Administrator Discretion.  The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Option at any time, subject to the terms of the Plan.  If so accelerated, such Option will be considered as having vested as of the date specified by the Administrator.

4.    Exercise of Option.  
(a)    Right to Exercise.  The Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of the Award Agreement.  The period (if any) during which Participant may exercise the Option after Participant ceases to be a Service Provider will commence on the date Participant ceases to actively provide services to the Company or a Parent or Subsidiary of the Company and will not be extended by any notice period mandated under employment laws in the jurisdiction where Participant is employed or providing services, or the terms of Participant’s employment or service agreement, if any; the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the Option (including whether Participant may still be considered to be providing services while on a leave of absence).
(b)    Method of Exercise.  The Option is exercisable by delivery of an exercise notice (the “Exercise Notice”) in the form attached as Exhibit C or in a manner and pursuant to such procedures as the Administrator may determine, which will state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan and the Award Agreement.  The Exercise Notice must be completed by Participant and delivered to the Company and must be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares and any Tax-Related Items (as defined in Section 6(a)) or evidence of arrangement for payment of such Tax-Related Items.  The Option will be deemed to be exercised upon receipt by the Company of such fully-executed Exercise Notice accompanied by the aggregate Exercise Price and payment to satisfy or evidence of arrangements to satisfy all Tax-Related Items.  
5.    Method of Payment.  Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the election of Participant:
(a)    cash; 
(b)    check; 
(c)    consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or
(d)    if Participant is a U.S. Service Provider, surrender of other Shares which have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares and any Tax-Related Items, provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any adverse accounting consequences to the Company.
6.    Taxes.  
(a)    Responsibility for Taxes.  Notwithstanding any contrary provision of the Award Agreement, no certificate representing the Exercised Shares will be issued to Participant unless and until satisfactory arrangements (as determined by the Administrator) will have been made by Participant with respect to the payment of income, employment, social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related Items”) which the Company or the Parent or Subsidiary employing or retaining Participant (the “Employer”) determines must be withheld with respect to the Option or the Exercised Shares.  In this regard, Participant acknowledges and agrees that: 
(i)    Participant is ultimately responsible for all Tax-Related Items and Participant’s liability for Tax-Related Items may exceed the amount withheld by the Company and/or the Employer, if any; 
(ii)    the Company and/or the Employer make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, including, but not limited to, the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired upon exercise of the Option and the receipt of any dividends; 

- 2 -

(iii)    the Company and/or the Employer do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result; 
(iv)    the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction if Participant is subject to tax in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable; and
(v)    the Company may refuse to honor the Option exercise and refuse to deliver any Shares pursuant to such exercise if Participant fails to make satisfactory arrangements for the payment of any Tax-Related Items hereunder at the time of exercise.
(b)    Withholding of Taxes.  Prior to the exercise of the Option, Participant will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all withholding and payment obligations of Tax-Related Items of the Company and/or the Employer.  In this regard, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or more of the following methods:
(i)    withholding from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Employer; 
(ii)    withholding from proceeds of the sale of Shares acquired upon exercise of the Option either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization) without further consent from Participant; 
(iii)    withholding otherwise deliverable Shares with a Fair Market Value equal to the minimum amount of Tax-Related Items that the Company and/or the Employer is required to withhold; and/or
(iv)    if Participant is a U.S. taxpayer, by surrender of other shares of Company common stock with a Fair Market Value equal to the amount of any Tax Related Items.
Alternatively, or in addition to the withholding methods above, if permissible under Applicable Laws, the Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit or require Participant to satisfy his or her obligations for Tax-Related Items, in whole or in part (without limitation) by delivery of cash or check to the Company or the Employer.
Depending on the method of withholding, the Company may withhold or account for Tax-Related Items by considering maximum or minimum applicable rates.  If withholding is performed from proceeds from the sale of Shares acquired upon exercise of the Option, the Company may withhold or account for Tax-Related Items by considering maximum applicable rates, in which case Participant will receive a cash refund of any over-withheld amount not remitted to applicable tax authorities on Participant’s behalf and Participant will have no entitlement to receive the equivalent amount in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the portion of the Option that was exercised, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.  
(c)    Notice of Disqualifying Disposition of ISO Shares.  If the Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant will immediately notify the Company in writing of such disposition.  Participant agrees that Participant may be subject to U.S. federal income tax withholding by the Company on the compensation income recognized by Participant.
(d)    Code Section 409A.  Under Code Section 409A, an option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per share exercise price that is determined by the U.S. Internal Revenue Service (the “IRS”) to be less than the fair market value of a share subject to such option on the date of grant (a “Discount Option”) may be considered “deferred 

- 3 -

compensation.”  A Discount Option may result in (i) income recognition by Participant prior to the exercise of the option, (ii) an additional twenty percent (20%) U.S. federal income tax, and (iii) potential penalty and interest charges.  The Discount Option may also result in additional state income, penalty and interest charges to Participant.  Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share Exercise Price of the Option equals or exceeds the Fair Market Value of a Share on the Date of Grant in a later examination.  Participant agrees that if the IRS determines that the Option was granted with a per Share Exercise Price that was less than the Fair Market Value of a Share on the Date of Grant, Participant will be solely responsible for Participant’s costs related to such a determination.
7.    Rights as Stockholder.  Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account).  After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares.
8.    No Guarantee of Continued Service.  PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE OPTION PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER OF THE COMPANY OR A PARENT OR SUBSIDIARY OF THE COMPANY AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER.  PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THE AWARD AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY OR ANY PARENT OR SUBSIDIARY OF THE COMPANY TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.
9.    Nature of Grant.  In accepting the Option, Participant acknowledges, understands and agrees that:
(a)    the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past; 
(b)    all decisions with respect to future option or other grants, if any, will be at the sole discretion of the Company; 
(c)    Participant is voluntarily participating in the Plan; 
(d)    the Option and any Shares acquired under the Plan, and the income and value of the same, are not intended to replace any pension rights or compensation;
(e)    the Option and any Shares acquired under the Plan, and the income and value of the same, are not part of Participant’s normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or payments or welfare benefits or similar payments; 
(f)    the future value of the Shares underlying the Option is unknown, indeterminable, and cannot be predicted with certainty; 
(g)    if the underlying Shares do not increase in value, the Option will have no value; 
(h)    if Participant exercises the Option and acquires Shares, the value of such Shares may increase or decrease in value, even below the Exercise Price;

- 4 -

(i)    unless otherwise provided in the Plan or by the Company in its discretion, the Option and the benefits evidenced by the Award Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and
(j)    in addition to subsections (a) through (i) above, the following provisions will also apply if Participant is a Service Provider outside the U.S.:
(i)the Option and the Shares subject to the Option, and the income and value from same, are not part of Participant’s normal or expected compensation or salary for any purpose; 
(ii)none of the Company, the Employer, or any Parent or Subsidiary of the Company shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the U.S. dollar that may affect the value of the Option or of any amounts due to Participant pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon exercise; 
(iii)no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from the termination of Participant’s status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is a Service Provider, or the terms of Participant’s employment or service agreement, if any), and in consideration of the grant of the Option to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, the Employer, or any Parent or Subsidiary of the Company, waives his or her ability, if any, to bring any such claim, and releases the Company, the Employer, and any Parent or Subsidiary of the Company from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim.
10.    No Advice Regarding Grant.  The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares.  Participant should consult with his or her personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan.
11.    Data Privacy.  Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in the Award Agreement and any other Option grant materials (“Data”) by and among, as applicable, the Employer, the Company and any Parent or Subsidiary of the Company for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan.  Participant understands that Data may include certain personal information about Participant, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all options or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor. 
Participant understands that Data will be transferred to E*TRADE Financial Services, Inc., or such other stock plan service provider as may be selected by the Company in the future (the “Designated Broker”), which is assisting the Company with the implementation, administration and management of the Plan.  Participant understands that the recipients of Data may be located in the U.S. or elsewhere, and that a recipient’s country of operation (e.g., the U.S.) may have different data privacy laws and protections than Participant’s country.  Participant understands that if he or she resides outside the U.S., he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative.  Participant authorizes the Company, the Designated Broker and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing Participant’s participation in the Plan.  Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan.  Participant understands that if he or she resides outside the U.S., he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing his or her local human 

- 5 -

resources representative.  Further, Participant understands that he or she is providing the consents herein on a purely voluntary basis.  If Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her status as a Service Provider and career with the Employer will not be adversely affected; the only consequence of refusing or withdrawing Participant’s consent is that the Company would not be able to grant Participant options or other equity awards or administer or maintain such awards.  Therefore, Participant understands that refusing or withdrawing his or her consent may affect his or her ability to participate in the Plan.  For more information on the consequences of his or her refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local human resources representative.
Finally, upon request of the Company or the Employer, Participant agrees to provide an executed data privacy consent form to the Employer or the Company (or any other agreements or consents that may be required by the Employer or the Company) that the Company and/or the Employer may deem necessary to obtain under the data privacy laws in Participant’s country, either now or in the future.  Participant understands that he or she will not be able to participate in the Plan if he or she fails to execute any such consent or agreement.
12.    Address for Notices.  Any notice to be given to the Company under the terms of the Award Agreement will be addressed to the Company at A10 Networks, Inc., 3 West Plumeria Drive, San Jose, CA 95134, or at such other address as the Company may hereafter designate in writing.
13.    Non-transferability of Option.  The Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant.  
14.    Successors and Assigns.  The Company may assign any of its rights under the Award Agreement to single or multiple assignees, and the Award Agreement shall inure to the benefit of the successors and assigns of the Company.  Subject to the restrictions on transfer herein set forth, the Award Agreement shall be binding upon Participant and his or her heirs, executors, administrators, successors and assigns.  The rights and obligations of Participant under the Award Agreement may only be assigned with the prior written consent of the Company.
15.    Additional Conditions to Issuance of Shares.  If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any U.S. federal, state, local or foreign law, the tax code and related regulations or under the rulings or regulations of the U.S. Securities and Exchange Commission (the “SEC”) or any other governmental regulatory body or the clearance, consent or approval of the SEC or any other governmental regulatory authority is necessary or desirable as a condition to the purchase by, or issuance of Shares, to Participant (or his or her estate) hereunder, such purchase or issuance will not occur unless and until such listing, registration, qualification, rule compliance, clearance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company.  Subject to the terms of the Award Agreement and the Plan, the Company shall not be required to issue any certificate or certificates for Shares hereunder prior to the lapse of such reasonable period of time following the date of exercise of the Option as the Administrator may establish from time to time for reasons of administrative convenience.
16.    Interpretation.  The Administrator will have the power to interpret the Plan and the Award Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares subject to the Option have vested).  All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons.  Neither the Administrator nor any person acting on behalf of the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or the Award Agreement.
17.    Electronic Delivery and Acceptance.  The Company may, in its sole discretion, decide to deliver any documents related to the Option or any future awards that may be granted under the Plan by electronic means.  Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or a third party designated by the Company.

- 6 -

18.    Agreement Severable.  In the event that any provision in the Award Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of the Award Agreement.
19.    Modifications to the Award Agreement.  The Plan is established voluntarily by the Company, it is discretionary in nature, and the Company, in its discretion, may elect to terminate, suspend or modify the terms of the Plan at any time, to the extent permitted by the Plan.  Participant agrees to be bound by such termination, suspension or modification regardless of whether notice if given to Participant of such event.  The Company reserves the right to revise the Award Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Code Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A of the Code in connection with the Option.  Further, the Company reserves the right to impose other requirements on Participant’s participation in the Plan, on the Option and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Participant to execute any additional agreements or undertakings that may be necessary to accomplish the foregoing.  Modifications to this Award Agreement or the Plan can be made only in an express written contract executed by Participant and a duly authorized officer of the Company.
20.    Waiver. Participant acknowledges that a waiver by the Company of breach of any provision of the Award Agreement shall not operate or be construed as a waiver of any other provision of the Award Agreement, or of any subsequent breach by Participant or any other Participant.
21.    Governing Law and Venue.  The Award Agreement will be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof.  For purposes of litigating any dispute that arises under the Option or the Award Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation will be conducted in the courts of Santa Clara County, California, or the U.S. federal courts for the Northern District of California, and no other courts, where the Option is made and/or to be performed.
22.    Language.  If Participant has received the Award Agreement or any other document related to the Option or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.
23.    Captions.  Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of the Award Agreement.
24.    Appendix.  Notwithstanding any provision of the Award Agreement, the Option grant shall be subject to any additional terms and conditions for Participant’s country set forth in the Appendix.  Moreover, if Participant relocates to one of the countries included in the Appendix, the terms and conditions for such country will apply to Participant to the extent the Company determines that the application of such terms and conditions to Participant is necessary or advisable for legal or administrative reasons.  The Appendix constitutes part of the Award Agreement.  
25.    Insider Trading.  By participating in the Plan, Participant agrees to comply with the Company’s policy on insider trading (to the extent that it is applicable to Participant).  Further, Participant acknowledges that Participant’s country of residence may also have laws or regulations governing insider trading and that such laws or regulations may impose additional restrictions on Participant’s ability to participate in the Plan (e.g., acquiring or selling Shares) and that Participant is solely responsible for complying with such laws or regulations.

EXHIBIT B
APPENDIX TO STOCK OPTION AGREEMENT 

Terms and Conditions
This Appendix includes additional terms and conditions that govern Participant’s participation in the Plan if Participant works and/or resides in one of the countries listed below.  If Participant is a citizen or resident of a country other than the one in which Participant is currently working (or is considered as such for local law purposes), or Participant transfers employment or residence to a different country after the Option is granted, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will apply to Participant. 
Capitalized terms used but not defined in this Appendix shall have the same meanings assigned to them in the Plan, the Notice of Grant or the Option Terms.  
Notifications 
This Appendix also includes information regarding certain other issues of which Participant should be aware with respect to Participant’s participation in the Plan.  The information is based on the securities, exchange control and other laws in effect in the respective countries as of February 2014.  Such laws are often complex and change frequently.  As a result, the Company strongly recommends that Participant not rely on the information noted herein as the only source of information relating to the consequences of participation in the Plan because the information may be out-of-date at the time Participant exercises the Option or sells any Shares acquired upon such exercise.  
In addition, the information contained herein is general in nature and may not apply to Participant’s particular situation and the Company is not in a position to assure Participant of any particular result.  Accordingly, Participant is advised to seek appropriate professional advice as to how the relevant laws in Participant’s country may apply to his or her individual situation.
If Participant is a citizen or resident of a country other than the one in which Participant is currently working (or is considered as such for local law purposes), or if Participant relocates to a different country after the Option is granted, the notifications contained in this Appendix may not be applicable to Participant in the same manner.

ARGENTINA
Terms and Conditions
Method of Payment.  The following provision replaces Section 5 of the Option Terms (Method of Payment) and supplements Section 6 (Taxes):
Notwithstanding any provision of the Plan to the contrary, payment of the aggregate Exercise Price and any Tax-Related Items withholding may only be made pursuant to a formal cashless exercise program adopted by the Company in connection with the Plan.  The Company reserves the right to provide Participant with additional methods of payment in the future depending on the development of local law. 
Notifications
Securities Law Notice.  Neither the Option nor the underlying Shares are publicly offered or listed on any stock exchange in Argentina.  The offer is private and not subject to the supervision of any Argentine governmental authority.
Exchange Control Information.  Following the sale of Shares and/or the receipt of dividends, Participant may be subject to certain restrictions in bringing such funds back into Argentina.  The Argentine bank handling the transaction may request certain documentation in connection with the request to transfer such proceeds into Argentina (e.g., evidence of the sale, proof of the source of the funds used to purchase such Shares, etc.) and, under certain circumstances, may require that 30% of the amount transferred into Argentina be placed in a non-interest bearing dollar deposit account for a holding period of 365 days.  
Participant is solely responsible for complying with applicable Argentine exchange control rules that may apply in connection with Participant’s participation in the Plan and/or the transfer of cash proceeds into Argentina.  Prior to transferring cash proceeds into Argentina, Participant should consult with his or her local bank and/or exchange control advisor to confirm what will be required by the bank because interpretations of the applicable Central Bank regulations vary by bank and exchange control rules and regulations are subject to change without notice.
Tax Reporting Obligation.  Shares acquired under the Plan and held by the Participant on December 31st of each year must be reported on the Participant’s annual tax return for that year.
AUSTRALIA
Terms and Conditions
Exercise of Option.  The following provision supplements Section 2 (Vesting Schedule) and Section 4(a) (Right to Exercise) of the Option Terms:
Notwithstanding any provision of the Plan or the Award Agreement, the Option shall not vest nor be exercisable until the earlier of the date on which (i) the shares of Common Stock underlying the Option are publicly traded, quoted or listed on a recognized exchange or normal securities market and are no longer subject to a market stand-off or lock-up period, (ii) the Option vests (in full or part) and is exercisable by reason of a Change in Control as determined by the Administrator (the "Liquidity Date").  Participant must maintain his or her status as a Service Provider through each date on the Vesting Schedule in the Notice of Grant and through the Liquidity Date in order to vest in any portion of the Option.  Should the Liquidity Date occur after any of the vesting dates set forth in the Vesting Schedule set forth in the Notice of Grant, Participant will receive a credit for any vesting that would have occurred under the Vesting Schedule once the Liquidity Date occurs and will continue to vest in accordance with the Vesting Schedule thereafter to the extent that Participant’s status as a Service Provider has not terminated. 
Furthermore, notwithstanding the vesting of any portion of the Option on the Liquidity Date or any vesting date thereafter, Participant will not be permitted to exercise any vested portion of the Option on any given vesting date unless and until the 

- 2 -

Fair Market Value of the Shares underlying the Option exceeds the Exercise Price for the Option (i) as of such vesting date, and (ii) for the 10 consecutive trading days immediately preceding such vesting date.  In the event that any portion of the vested Option is not exercisable on the vesting date as a result of the immediately preceding sentence, then the Option will not be exercisable until such date that is the first trading day following the first period of 10 consecutive trading days on which the Fair Market Value per share underlying the Option has exceeded the per-share Exercise Price for the Option.  For the sake of clarity, this paragraph will not apply if the vesting of any portion of the Option on a Liquidity Date is as a result of a Change in Control.
Finally, notwithstanding the Term/Expiration Date set forth in the Notice of Grant, the Option shall automatically expire in the event that the Option has not vested and become exercisable pursuant to the preceding paragraphs within six years and 11 months following the Date of Grant.
Notifications
Securities Law Notice.  If Participant acquires Shares under the Plan and offers such Shares for sale to a person or entity resident in Australia, the offer may be subject to disclosure requirements under Australian law.

SPAIN
Terms and Conditions
Nature of Grant.  This provision supplements Section 9 of the Option Terms (Nature of Grant):
By accepting the Option, Participant consents to participation in the Plan and acknowledges that he or she has received a copy of the Plan.
Participant understands that the Company has unilaterally, gratuitously and discretionally decided to grant options under the Plan to individuals who may be Service Providers of the Company or its Parent or Subsidiaries throughout the world.  This decision is a limited decision that is entered into upon the express assumption and condition that any grant will not bind the Company or any Parent or Subsidiary of the Company other than as expressly set forth in the Award Agreement.  Consequently, Participant understands that the Option is granted on the assumption and condition that the Option and any Shares issued upon exercise of the Option are not a part of any employment or service contract (either with the Company or any Parent or Subsidiary of the Company) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation) or any other right whatsoever.
Further, Participant understands and agrees that, unless otherwise expressly provided for by the Company or set forth in the Plan or the Award Agreement, the Option will be cancelled without entitlement to any Shares underlying the Option if Participant’s status as a Service Provider is terminated for any reason, including, but not limited to: resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without cause, material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, or under Article 10.3 of Royal Decree 1382/1985.

In addition, Participant understands that this grant would not be made to Participant but for the assumptions and conditions referred to above; thus, Participant acknowledges and freely accepts that, should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then any grant of, or right to, the Option shall be null and void.

Securities Law Notice. The Option described in the Award Agreement does not qualify under Spanish regulations as a security.  No “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory in connection with the grant of the Option. The Award Agreement has not been, nor will it be, registered with the Comisión Nacional del Mercado de Valores, and does not constitute a public offering prospectus.
Foreign Property Reporting.  To the extent that Participant holds rights or assets (e.g., Shares, cash, etc.) in a bank or brokerage account outside of Spain with a value in excess of €50,000 per type of right or asset as of December 31 each year, Participant is required to report information on such rights and assets on his or her tax return for such year.  Shares acquired under the Plan constitute securities for purposes of this requirement, but the Option (whether vested or unvested) is not considered an asset or right for purposes of this requirement.  
If applicable, Participant must report the assets or rights on Form 720 by no later than March 31 following the end of the relevant year. After such assets or rights are initially reported, the reporting obligation will only apply for subsequent years if the value of any previously-reported assets or rights increases by more than €20,000.

Accordingly, Participant should consult with his or her personal tax and legal advisors to ensure that Participant is properly complying with his or her reporting obligations.

Terms and Conditions
Joint Election for Transfer of Liability for Employer National Insurance Contributions.  The following provision supplements Section 6 of the Option Terms (Taxes): 
As a condition of participation in the Plan and the exercise of the Option, Participant agrees to accept any liability for secondary Class 1 National Insurance contributions (“NICs”) that may be payable by the Company or the Employer in connection with the Option and any event giving rise to Tax-Related Items (the “Employer NICs”).  The Employer NICs may be collected by the Company or the Employer using any of the methods described in the Plan or the Award Agreement. 
Without prejudice to the foregoing, Participant agrees to execute a joint election with the Company and/or the Employer (a “Joint Election”), the form of such Joint Election being formally approved by Her Majesty’s Revenue and Customs (“HMRC”), and any other consent or elections required to accomplish the transfer of the Employer NICs liability to Participant.  Participant further agrees to execute such other elections as may be required by any successor to the Company and/or the Employer for the purpose of continuing the effectiveness of Participant’s Joint Election.  If Participant does not complete the Joint Election prior to exercise of the Option, or if approval of the Joint Election is withdrawn by HMRC and a new Joint Election is not entered into, the Option shall become null and void and may not be exercised, without any liability to the Company, the Employer or any Parent or Subsidiary of the Company.
Tax Withholding.  The following provision supplements Section 6 of the Option Terms (Taxes):
Participant agrees that the Company and/or the Employer may calculate the income tax to be withheld and accounted for by reference to the maximum applicable rates, without prejudice to any right that Participant may have to recover any overpayment from HMRC.
If payment or withholding of Participant’s income tax liability is not made within 90 days after the end of the U.K. tax year (April 6 - April 5) in which the event giving rise to such income tax liability occurs or such other period specified in Section 222(1)(c) of ITEPA 2003 (the “Due Date”), the amount of any uncollected income tax will constitute a loan owed by Participant to the Employer, effective on the Due Date.  Participant agrees that the loan will bear interest at the then-current Official Rate of HMRC, it will be immediately due and repayable, and the Company or the Employer may recover it at any time thereafter by any of the means referred to in the Plan or the Award Agreement.

- 14 -

Notwithstanding the foregoing, if Participant is a director or executive officer of the Company (within the meaning of and subject to Section 13(k) of the Exchange Act), Participant will not be eligible for such a loan to cover the income tax due and the amount of any uncollected income tax may constitute a benefit to Participant on which additional income tax and employee NICs may be payable. Participant will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company and/or the Employer (as appropriate) for the value of any employee NICs due on this additional benefit, which may be recovered from Participant by the Company or the Employer at any time thereafter by any of the means referred to in the Plan or the Award Agreement.
