As previously announced in a Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on February 9, 2017, Greg Straughn stepped down as Chief Financial Officer (“CFO”) of A10 Networks, Inc. (the “Company”), effective as of February 23, 2017. Mr. Straughn’s departure is not the result of any material disagreement with the Company regarding its operations, policies or practices.

In connection with Mr. Straughn’s transition and departure, the Company and Mr. Straughn entered into a letter agreement on March 29, 2017, that confirms the terms of Mr. Straughn’s transition of employment with the Company (the “Transition Letter”).

The Transition Letter provides that between February 23, 2017, and through Mr. Straughn’s actual termination of employment with the Company (the “Transition Period”), which is expected to occur on April 1, 2017, Mr. Straughn will continue to be employed by the Company to assist in the transition of his duties. During the Transition Period, Mr. Straughn will continue to receive his current annualized salary, will continue to vest in his equity awards subject to their terms, and will continue to be eligible to participate in the Company’s benefits plans, subject to their terms. Subject to the successful transition of the CFO role, Mr. Straughn will be entitled to receive a one-time cash bonus of $30,000.

The Transition Letter also amends that certain Change in Control and Severance Agreement by and between Mr. Straughn and the Company dated December 1, 2013, the form of which was previously filed with the SEC on March 10, 2014, as Exhibit 10.25 to Amendment No. 1 to Form S-1 (the “Change in Control and Severance Agreement”), to provide, among other things, that if the Company has not terminated Mr. Straughn’s employment with the Company for Cause (as defined in the Change in Control and Severance Agreement) and Mr. Straughn has satisfied certain other conditions, including timely signing and not revoking the Separation Agreement and Release attached to the Transition Letter upon termination of his employment, then (i) Mr. Straughn will be entitled to receive continuing transition payments at a rate equal to Mr. Straughn’s base salary rate, as in effect immediately prior to the termination of his employment, for a period of nine months, and, provided that Mr. Straughn timely elects and remains eligible for continued group health plan benefits, COBRA premiums to maintain health insurance coverage for him and any eligible dependents for up to nine months following such termination and (ii) any outstanding stock options held by Mr. Straughn that are exercisable as of the date of termination of Mr. Straughn’s employment will be amended such that they remain exercisable through the one year anniversary of such date.

The foregoing summary of the Transition Letter does not purport to be complete and is qualified in its entirety by the full text of the Transition Letter, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ending March 31, 2017.
