Dear Chris,

I am pleased to confirm the offer for you to join A10 Networks (the “Company”),
in the position of Executive Vice President Worldwide Sales at our Corporate
Headquarters located in San Jose, CA. This is a full time, regular position,
reporting to Lee Chen, CEO. The terms of our offer and the benefits currently
provided by the Company are as follows:

Total Target Cash Compensation. Your 2018 annual total target cash compensation
will be $630,000 distributed sixty percent (60%) base salary and forty percent
(40%) incentive. Effective January 1, 2019, your total target cash compensation
will be distributed fifty percent (50%) base salary and fifty percent (50%)
incentive.

Salary. Your starting base salary will be at a rate of $378,000 per year subject
to annual review, less applicable taxes and other withholdings in accordance
with the Company’s normal payroll schedule.

Incentive. You will be eligible to receive an annual performance based bonus
target of $252,000, paid in accordance with the A10 Executive Cash Incentive
Plan.

Sign-on Bonus. You are also eligible to receive a sign-on bonus in the amount of
$75,000 less statutory taxes; federal, state and employment upon commencement of
employment, provided you agree to repay this amount to the Company should you
voluntarily terminate your employment within one year.

Restricted Stock Grant. We will recommend to the Board of Directors of the
Company (the “Board”) that you be granted an award of restricted stock units
(the “RSU Award”) to cover a number of shares of the Company’s Common Stock
equivalent to a value of US$700,000 under the Company’s 2014 Equity Incentive
Plan, as amended (the “Plan”).  Each restricted stock unit granted represents
the right to receive one share of the Company’s Common Stock upon vesting. 25%
of the recommended RSU Award shall vest on each yearly anniversary of your vest
base date (assuming your continued employment with the Company on each vesting
date) such that the entire RSU Award shall vest over 4 years (for administrative
reasons, the vest base date will be the 5th day of the month following your
employment start date).  The number of shares subject to the RSU Award will be
determined by dividing the dollar value of the award by the average closing
trading price of the Company’s Common Stock during the 30 calendar day period
prior to your employment start date, rounded down to the nearest whole share.

Stock Option Grant. We will recommend to the Board that you be granted a stock
option (the “Option Award”) to purchase a number of shares of the Company’s
Common Stock equivalent to a value of US$700,000 of the Company’s Common Stock
under the Plan. The exercise price for the Option Award will be no less than the
fair market value of one share of the Company’s Common Stock on the date of
grant, as determined by the Board in accordance with the terms of the Plan.
Generally, the Option Award shall vest and become exercisable (assuming your
continued employment with the Company or one of its subsidiaries or affiliates
through each vesting date) as follows: twenty-five percent (25%) of the shares
subject to the Option Award shall vest on the one-year anniversary of the
vesting commencement date (as set  forth in the relevant notice of grant
provided with your Option Award agreement) and an additional one-forty-eighth
(1/48) of  the shares subject to the Option Award shall vest at the end of each
full month  thereafter. The number of shares subject to the Option Award will be
determined by using the Company’s standard Black-Scholes assumptions applied as
of the date of grant.

cause. Any statements or representations to the contrary (and, indeed, any
statements contradicting any provision in this letter) should be regarded by you
as ineffective. Further, your participation in any stock option or benefit

particular period of time. Any modification or change in your at will employment
status may only occur by way of a written employment agreement signed by you and
the Chief Executive Officer of the Company.
