Dear Suzy, On behalf of 8x8, Inc., a Delaware corporation (“8x8,” or the "Company"), I am pleased to offer you employment with 8x8 as Senior Vice President and Chief Accounting Officer, beginning on a mutually agreed upon date no later than May 20, 2022. The terms of your employment relationship with the Company will be as set forth below. 1. Position. You will become Senior Vice President and Chief Accounting Officer. As such, you will have responsibilities as determined by your manager, which shall be the Company's Chief Financial Officer, and by the Board of Directors. Your duties and responsibilities are subject to change depending on the needs of the Company. 2. Base Salary. You will be paid an annualized salary of $340,000, payable in accordance with the Company's standard payroll policies, and subject to required withholding. a. Salary Review. Your base salary will be reviewed as part of the Company's normal salary review process. b. Expenses. You will be reimbursed for all reasonable and necessary business expenses incurred in the performance of your duties in accordance with the Company's Employee Handbook and other Company policies. 3. Bonus. You will be eligible to participate in 8x8’s discretionary incentive plan. Your total annual target bonus will be 45% of your base salary, and any bonus earned with respect to the financial period in which your employment commences will be pro-rated accordingly. The bonus may be paid in cash or stock at the Company’s discretion. The actual bonus amount could be larger or smaller than the target amount, based on your performance, and the performance of the Company. The exact bonus amount is at the sole discretion of the Company. The components and respective attainment will be determined by your management team and the Company, with details to be communicated. 4. Initial Stock Awards. Subject to approval by the Board of Directors, you will be granted an award of approximately $1,300,000 in value of restricted stock units (“RSUs”), representing the right to acquire shares of 8x8, Inc. Common Stock upon vesting. The actual number of shares subject to the RSU award will be determined by dividing the value of the RSU award by the trailing 20-trading-day average of 8x8’s closing stock price prior to the RSU grant date. We anticipate that this award will be subject to the terms of the 8x8, Inc. Amended and Restated 2012 Equity Incentive Plan, as amended (a copy of which is available with 8x8’s SEC DocuSign Envelope ID: 6D3027FF-8D14-40F4-9A9E-1F3598333855
Page 2 of 4 filings at www.sec.gov). The shares will vest over a three-year period, with one-third (1/3) vesting on the first anniversary of your RSU grant date, and the remainder vesting in eight (8) equal quarterly installments thereafter, subject to your continued employment or other qualifying association with the Company or any of its affiliates. 5. Severance Benefits. You will be entitled to benefits under the 8x8, Inc. 2017 Executive Change- in-Control and Severance Policy (the “Policy”), in accordance with the terms thereof. Such benefits include potential vesting acceleration of stock-based compensation and/or cash severance upon the termination of your employment under specified circumstances, including in connection with a Change-in-Control (as defined in the Policy), subject to the terms and conditions of the Policy. A summary of the benefits under the Policy, as in effect on the date of this offer letter, is attached for reference as Exhibit A. 6. Benefits.
