Form of Stock Option Agreement pursuant to the 2008 Stock Plan

A10 Networks, Inc. (the "Company") hereby grants an option (the “Option”) to purchase shares of its Common Stock (“Shares”) to the optionee named below on the terms and conditions set forth in this cover sheet, the Company’s 2008 Stock Plan, and all exhibits attached hereto (together, the “Stock Option Agreement"):

Exercise and Vesting Schedule:

The Option granted hereunder may be exercised, in whole or in part, based on the vesting schedule as set forth below.

[INSERT VESTING SCHEDULE]

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.

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.

    

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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."

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.

The Company may, in its sole discretion, decide to deliver any documents related to your current or future participation in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

The provisions of this Stock Option Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

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.

You acknowledge that a waiver by the Company of breach of any provision of this Stock Option Agreement shall not operate or be construed as a waiver of any other provision of this Stock Option Agreement, or of any subsequent breach by you or any other optionee.

The text of the Plan is incorporated into this Stock Option Agreement by reference. This Stock Option Agreement (along with all exhibits and attachments) and the Plan constitute the entire understanding between you and the Company regarding this Option. Any prior agreements, commitments or negotiations concerning this Option are superseded.

    

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 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.
