RE: 8x8, Inc. Managing Director of European Operations

Dear Mary Ellen,

This letter supersedes and replaces in its entirety the employment agreement between you and 8x8, Inc. ("8x8" or "the Company") dated October 6, 2014, as amended to date. This letter confirms that, effective as of November 1, 2018, you ceased serving as the Company's Chief Financial Officer and became the Managing Director of European Operations. The terms of your new employment relationship with the Company, effective as of November 1, 2018, will be as set forth below.

1. Position. Your position will be Managing Director of European Operations. You will cease to be an Executive Vice President of the Company, but you will continue to report to the Company's Chief Executive Officer. As such, you will have responsibilities as determined by the Company's Chief Executive Officer. You will promptly relocate to the Company's London office and will work from that office until on or around May 31 2019 (but no later than June 14, 2019), at which time you will return to the United States and continue to be employed by the Company on a part-time basis until September 30, 2019. Your duties and responsibilities are subject to change depending on the needs of the Company. Subject to further advice from employment and tax counsel in the United States and United Kingdom, you may become a temporary employee of 8x8 UK Limited for the duration of your employment in the United Kingdom.

Unless you and the Company agree otherwise, you will cease to serve as director of each subsidiary of which you currently serve as a director, other than 8x8 UK Limited. You will remain a director of 8x8 UK Limited until the Company's appointment of a successor, or until your earlier removal or resignation.

2. Termination Date. Your employment with the Company will terminate on September 30, 2019 (the "Termination Date"), unless you and the Company mutually agree to alter this date, and otherwise subject to the terms and conditions of this offer letter.
3. Compensation.
1. Base Salary. You will be paid an annualized salary of $290,000 payable in accordance with the Company's standard payroll policies subject to normal required withholding.
2. Expenses. You will be provided with a lump-sum payment of $50,000 to offset your housing costs while living in the UK. You will be reimbursed for all reasonable and necessary business expenses incurred in the performance of your duties as provided in the Company's Employee Handbook.

8x8, Inc.                                 2125 O'Nel Drive                                 San Jose, CA 95131                                 Phone: 408.727.1885                                 Fax: 408.980.0432

3. Management Incentive Plan. You will be eligible to participate in the Company's Management Incentive Plan while you are a full-time employee, with a target annual bonus of 50% of your annual base salary, and otherwise on substantially the same terms as your current participation.
4. Stock Awards; No Participation in Policies.
1. You will not be entitled to any additional awards of stock-based compensation, but your existing equity awards will continue to vest subject to your continued employment or other qualifying association with the Company or any of its subsidiaries, in accordance with the terms and conditions of such equity awards, and further subject to this Section 4.
2. Except as set forth in Section 4(c) below, as of the Effective Date, you shall no longer be eligible to participate in any change-in-control or severance policies or agreements, including but not limited to, the 8x8, Inc. 2015 Amended and Restated Executive Change-in-Control and Severance Policy (Amended and Restated as of October 1, 2017) and the 8x8, Inc. 2017 Executive Change-in-Control and Severance Policy.
3. Involuntary Termination: In the event that you are subject to an Involuntary Termination (as defined below) prior to the Termination Date, including due to a Change-in-Control, then (to the extent the underlying shares have not vested between the date of this letter and the date of your Involuntary Termination) the RSU awards and options listed on Exhibit A hereto will accelerate and vest as to the number of shares set forth for each award in Exhibit A. With respect to PSUs, the performance period shall be deemed to end on the date of the termination of your employment (the "Involuntary Termination Date"), and you will receive shares of stock based on the Company's performance through the Involuntary Termination Date (i.e., at 100% target, you would receive the number of shares set forth for each award in Exhibit A).

"Involuntary Termination" means without your express written consent, a termination of your employment with the Company without Cause that prevents continued vesting of your unvested equity.

"Cause" means: (i) any act of personal dishonesty taken by you in connection with your responsibilities in your service to the Company which is intended to result in your personal enrichment; (ii) your conviction of a felony; (iii) any act by you that constitutes material misconduct and is injurious to the Company; (iv) any breach of fiduciary duty to the company, (v) a material breach of any agreement with the Company, or (vi) your initiating litigation against the Company (excluding any litigation to enforce the Company's compliance with the terms of this agreement). For purposes of this clause (d), "Company" includes the Company and each of its subsidiaries.

"Change-in-Control" means the consummation of any of the following corporate transactions:

5. Benefits. The Company will continue to make available to you standard medical, dental, life and disability insurance benefits, as well a 401(k) Plan, and Employee Stock Purchase Plan.
