Offer Letter by and between the Registrant and Anand Eswaran, dated December 23, 2019

It is my pleasure to offer you a full-time position with RingCentral, Inc. (“Company”) as President, reporting to Vlad Shmunis, CEO. Your responsibilities in this role will include direct reporting responsibility for the Company's go-to-market, product, and human resources functions, as well as other responsibilities and functions reasonably assigned to you by the CEO. Pending satisfactory completion of our pre-employment checks and your satisfaction of the other terms and conditions described herein, your employment start date (the “Start Date”) shall be January 13, 2020 or a sooner date if mutually agreed.

Base Salary. Your initial annualized base salary will be $600,000, which will be paid on a semi-monthly basis, subject to applicable withholdings. Your base salary may be adjusted from time to time in the Company’s sole discretion.

Bonus. On a quarterly basis, you may be eligible to receive a management-by-objective bonus (“MBO”) in the target gross amount of 100% of your quarterly base salary ($150,000 per quarter; $600,000 per year) based upon achievement of the performance objectives established by the Company’s board of directors or a committee of the board (in either case, the “Board”) and the Board’s assessment of achievement of those objectives, as well as satisfying the other terms and conditions of the bonus plan approved by the Board. More information about the MBO is available in the RingCentral Executive Incentive Plan. As a member of the executive team, the achieved portion of your MBO currently will be paid in accordance with the Company’s Key Employee Equity Bonus Plan, in which the achieved portion of your MBO is paid on a quarterly basis in the form of fully-vested restricted stock units that cover shares of the Company’s Class A common stock (“RSUs”).

Equity Award. Subject to approval of the Board, you will be granted RSUs with an initial value of $16,000,000 (the “Initial Value”) (the “Initial Equity Grant”). The actual number of RSUs granted to you will equal the Initial Value divided by the monthly average closing price of a share of the Company’s Class A common stock (as quoted on the New York Stock Exchange) during the calendar month in which your Start Date occurs. The RSUs will be granted to you only if you remain an employee of the Company through the grant date. Your RSUs shall be subject to the terms of the Company’s 2013 Equity Incentive Plan (the “2013 Plan”) and an RSU agreement between you and the Company (together with the 2013 Plan, the “Equity Documents”). Subject to the paragraph below, your RSUs shall vest over a 4-year period as follows: provided you remain a service provider of the Company, 1/16^th of the RSUs shall vest on each Quarterly RSU Vesting Date beginning on February 20, 2020. The “Quarterly RSU Vesting Dates” are February 20, May 20, August 20, and November 20 of each year. No right to any stock is earned or accrued until such time that vesting occurs, nor does the grant confer any right to continue vesting or employment.

You will be eligible to participate in the Company’s Equity Acceleration Policy, as amended (“EAP”). As more fully set forth therein, if you experience a “Qualified Termination” (as defined in the EAP), one hundred percent (100%) of your then-outstanding unvested RSUs shall vest if you satisfy the terms and conditions set forth in the EAP.

Beginning in 2021, you are eligible for annual Company equity awards commensurate with your position and the approval of the Board and subject to any terms and conditions approved by the Board (each, an “Additional Equity Award”). Beginning in 2021, and subject to Board approval, your performance and your remaining an employee in good standing with the Company, it is anticipated that your Additional Equity Award may have a target value of

approximately fifty percent (50%) of the Initial Equity Grant. The Additional Equity Award shall be subject to the terms of the Equity Documents and shall vest over a 4-year period as follows: provided you remain a service provider of the Company, 1/16^th of the RSUs shall vest on each Quarterly RSU Vesting Date beginning on February 20, 2021. For clarity, the Initial Equity Grant and the Additional Equity Awards shall be deemed time-based RSUs. Notwithstanding anything to the contrary contained herein with respect to the Additional Equity Award, if the Company introduces and implements performance-based RSUs as part of the Company’s 2021 executive compensation, then some or all of the Additional Equity Award shall be subject to performance-based vesting on substantially similar terms and conditions as the performance-based vesting terms of other similarly-situated Company executives.

Severance. In the event of (a) a termination of your employment by the Company other than for “Cause” (as defined below), death or “Disability” (as defined in the EAP), or (b) your termination of employment for “Good Reason” (as defined in the EAP), then, subject to your satisfying the conditions set forth in Exhibit A attached hereto, you will be entitled to the following:

(a)Cash. Cash severance equal to twelve (12) months of your then-current base salary, payable in semi-monthly installments in accordance with the Company’s payroll procedures,

(b)COBRA. If you elect continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) within the time period prescribed pursuant to COBRA for you and your eligible dependents, then the Company will reimburse you for the COBRA premiums for such coverage (at the coverage levels in effect immediately prior to your termination) until the earlier of (i) a period of 12 months from the date of termination or (ii)) the date upon which you and/or your eligible dependents are no longer eligible for COBRA continuation coverage. or, in the event providing such benefit would result in a violation of applicable law as determined by the Company, in its discretion, a lump sum payment of $30,000, less applicable withholding, in lieu of such COBRA reimbursement,

(c)Acceleration of Vesting.

1)Pursuant to the EAP, if such termination occurs during the Change in Control Period (as defined in the EAP, as amended to begin 90 days prior to a Change in Control (as defined in the EAP)), 100% accelerated vesting of your then-outstanding and unvested Company equity awards that are subject to time-based vesting conditions (including, without limitation, time-based RSUs granted to you) subject to the terms and conditions of the EAP; and

2)If such termination occurs outside of the Change in Control Period (as defined above), accelerated vesting of the portion of each of your then-outstanding and unvested Company equity awards that are subject to time-based vesting conditions (including, without limitation, time-based RSUs granted to you) that would have vested had you remained employed with the Company through the date that is twelve (12) months following your effective last day with the Company.

For purposes of this letter, “Cause” has the meaning set forth in the EAP, as amended to (a) include your failure to satisfy the Relocation Condition (as defined below), and (b) with respect to Section 16(a)(ii) of the EAP, allow you at least thirty (30) days to cure any such breach or failure after receiving written notice from Company of such breach or failure.

Benefits.  You will be eligible to participate in the Company’s employee benefits plans generally available to the Company’s senior executives subject to their terms, including any eligibility requirements.  You will be provided with Company-wide paid holiday days and paid-time off in accordance with the Company’s paid time off policy, as may be amended from time to time.

You should note that the Company may modify job titles, job duties, compensation, and benefits from time to time as it deems necessary and in its sole discretion.

(a)The Company will pay or reimburse you for the expenses that you reasonably incur on or before September 8, 2020 (the “Relocation Date”), in connection with your permanent relocation from the Seattle, Washington to the San Francisco-Bay Area, California by the Relocation Date (such condition referred to herein as the “Relocation Condition”), including:

For clarity, all Relocation Expenses must be incurred during calendar year 2020. The Company will not reimburse you for Moving Expenses in excess of $45,000 in the aggregate.

Legal Expenses. You are eligible to receive reimbursement for reasonable legal expenses related to this letter and affiliated documents up to $5,000 (“Legal Expenses”). You must submit written documentation of the Legal Expenses within 45 days after the Legal Expenses are incurred in order to receive any reimbursement for such Legal Expenses. Reimbursements will be paid to you, grossed up for applicable tax withholdings (if any), within 30 days after the Company receives written documentation of the Legal Expenses in accordance with the previous sentence.

Anand, I really look forward to working with you. We have high hopes that you will contribute in a very tangible and visible manner to our continued success.

The receipt of any severance under this letter is subject to you signing and not revoking a general release of claims in a form reasonably acceptable to the Company and in a manner that is otherwise consistent with the terms of this letter (the “Release”); provided that such Release is effective within sixty (60) days following your termination of employment (the “Release Deadline”).  No severance payment will be made until the Release becomes effective. Moreover, as a condition precedent to receiving COBRA premiums, you must complete and return a Form W-9 to RingCentral within sixty (60) days following the termination of your employment. If the Release is not effective by the Release Deadline, you forfeit your right to any severance benefits under this letter. Subject to any payment delay necessary to comply with Section 409A (as defined below), your severance under this letter will be paid on, or, in the case of installments, will not commence until, the first Company payroll date following the effective date of the Release (or, in the case of payments that qualify as Deferred Compensation, on the sixty-first (61^st) day following your separation from service). If you die before all amounts have been paid, such unpaid amounts will be paid to your designated beneficiary, if living, or otherwise to your personal representative in a lump-sum payment (less any withholding taxes) as soon as possible following your death.

It is the intent of this letter that all payments and benefits hereunder comply with or be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and the final regulations and any guidance promulgated thereunder and any applicable state law requirements (“Section 409A”) so that none of the payments and benefits to be provided under this letter will be subject to the additional tax imposed under Section 409A, and any ambiguities or ambiguous terms herein will be interpreted to be exempt or so comply. Each payment and benefit payable under this letter is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. You and the Company agree to work together in good faith to consider amendments to this letter and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A.

Notwithstanding anything to the contrary in this letter, no separation pay or benefits will be paid or provided to you, if any, pursuant to this letter that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Section 409A (together, “Deferred Compensation”) or otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) until you have a “separation from service” within the meaning of Section 409A. Further, if at the time of your termination of employment, you are a “specified employee” within the meaning of Section 409A, payment of such Deferred Compensation will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under Section 409A, which generally means that you will receive payment on the first payroll date that occurs on or after the date that is six (6) months and one (1) day following your termination of employment, or your death, if earlier (the “Six-Month Delay”). All subsequent Deferred Compensation, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if you die following your termination but prior to the six (6) month anniversary of your termination, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of your death and all other Deferred Compensation will be payable in accordance with the payment schedule applicable to each payment or benefit.
