2022 NEO Equity Compensation Program Questions and Answers

ELIGIBLE EMPLOYEES: All NEOs (except CEO)

This document constitutes the RingCentral, Inc. 2022 NEO Equity Compensation Program (“NEO Equity Plan”). RingCentral, Inc. is referred to as “RingCentral,” “we,” “us” and “our.”

The NEO Equity Plan provides you with an opportunity to receive a portion of your base salary for the period from January 1, 2022 through December 31, 2022 in the form of restricted stock units (“RSUs”) under the Company’s 2013 Equity Incentive Plan (the “Equity Incentive Plan”) under the terms and conditions described in this Q&A and in the Election Form (attached as Exhibit A hereto). The NEO Equity Plan will not change the value of your base salary.

All Named Executive Officers (as defined in the Proxy Rules under the Securities Exchange Act of 1934) other than the CEO may voluntarily participate in the NEO Equity Plan in full. This means that a portion of their base salary for the period from January 1, 2022 through December 31, 2022 will be paid entirely in RSUs in lieu of cash.

For 2022, $60,000 of your base salary will be paid in cash, less applicable withholdings and deductions. This means that you will receive $2,500, less applicable withholdings and deductions, of your salary in cash twice a month for the period from January 1 through December 31, 2022. The cash amount will be sufficient to cover deductions for health benefits and 401(k) contributions, and a portion of ESPP withholding (see Question 15). The remainder of your salary for this period will be paid in RSUs.

The RSUs will be granted and fully vested as follows for the following base salary periods:

•For the period from January 1, 2022 through February 15, 2022, the RSUs will be granted and vested on January 3, 2022.

•For the period from February 16, 2022 through May 15, 2022, the RSUs will be granted and vested on February 15, 2022.

•For the period from May 16, 2022 through August 15, 2022, the RSUs will be granted and vested on May 16, 2022.

•For the period from August 16, 2022 through November 15, 2022, the RSUs will be granted and vested on August 15, 2022.

•For the period from November 16, 2022 through December 31, 2022, the RSUs will be granted and vested on November 15, 2022.

Please see below in Question 9 for more information regarding the vesting and timing of issuance of your RSUs.

Participation in the NEO Equity Plan will not affect your MBO. Your quarterly MBO will be calculated based on your full quarterly gross salary amount, whether your salary is paid all in cash or a portion is paid in RSUs.

An email with the Election Form will be sent to you via Docusign or Workday. If you would like to opt into this program and receive a portion of your base salary for the period from January 1, 2022 through December 31, 2022 in the form of RSUs, you must acknowledge/agree to the Election Form by December ___, 2021 at 8 pm PST ( (the “Submission Deadline”).

This is an all-or-nothing choice. If you participate in the NEO Equity Plan, you must participate with respect to either (a) all but $60,000 of your gross base salary, subject to applicable deductions and withholdings, for the entire period from January 1, 2022 through December 31, 2022 or (b) none of your gross base salary during that period.

For each corresponding 2022 base salary period described in Question 4, the number of RSUs you receive will be determined based on (i) the U.S. dollar value of the portion of your base salary to be paid in RSUs, (ii) divided by the Calculation Price, and (iii) rounded up to the nearest whole number.

Any RSUs you receive for a portion of your base salary will be 100% vested and settled in shares of Class A common stock on the first trading day on or after January 1, February 15, May 15,, August 15, or November 15, as applicable, subject to your continued employment with RingCentral or an affiliated entity through the vesting/issuance date. Shares of Class A common stock issued to you can be sold immediately (subject to any required administrative processing time and any applicable insider trading policy).

Although the intent of using the Calculation Price (under Question 8) was designed to protect you from much of the potential market risk, it is possible that you could end up with sale proceeds from the shares that is less than the cash equivalent of the base salary you would have otherwise been paid in cash.

If you leave RingCentral during the applicable period for which you received a grant of RSUs in lieu of cash, you will be entitled to keep the RSUs.

You will be taxed when the RSUs are granted to you because they will be fully vested at grant. The RSUs will be taxed as income on the dates of vesting at your applicable income tax rate, based on the value of the RSUs on the dates of vesting. Please see the attached Employee Information Supplement.

Please see the attached Employee Information Supplement. The Company will withhold a number of shares upon vesting of the RSUs to cover the amount of the tax owed and will issue you the remainder of the shares (net issuance).

No, you will pay taxes through net issuance of the shares during the period of the program.

No, if you receive a portion of your base salary in RSUs, the value of the RSUs will not be included as compensation for purposes of the calculation of contributions under the ESPP or 401(k) plan. You can continue to contribute amounts into the ESPP and 401(k) plan from your $60,000 cash compensation as defined under the applicable plan, provided that you are otherwise eligible for such plan. During the period of November 15, 2021 through May 12, 2022, and the period from May 13, 2022 through November 12, 2022, your participation in the 2022 plan (and, if applicable, your prior participation in the 2021 plan) will reduce your maximum contribution to the ESPP for the May 12, 2022 and November 12, 2022 purchases to 15% of the base salary paid in those periods in cash. With respect to the 401(k) plan, you will still be able to reach the maximum employee contribution amount for 2022 by increasing your contribution percentage in each paycheck. However, because the maximum employer match per paycheck under the 401(k) plan is limited to 3% of cash compensation, you will not be able to reach the maximum employer match in 2022 (the maximum possible will be approximately $1,800).

Your specific personal financial consequences and U.S. federal, state and local tax consequences depend upon your individual circumstances. Accordingly, we strongly recommend that you seek the advice of a qualified financial and tax adviser regarding your participation in the NEO Equity Plan.
