Offer Letter by and between the Registrant and Vaibhav Agarwal, dated July 21, 2016

It is my pleasure to offer you a full-time exempt position with RingCentral, Inc., a Delaware corporation (the “Company” or “RingCentral”), as VP & Corporate Controller, reporting to Mitesh Dhruv, SVP of Finance & Strategy.

As a condition of your employment, you will need to sign our standard employee invention assignment and confidentiality agreement (“PIIA”) and other standard Human Resources documents, as requested by the Company.

For purposes of federal immigration law, you may be required to provide to us documentary evidence of your identity and eligibility for employment in the United States. You must provide such documentation to us within three (3) business days of request as a condition of this offer and of your employment. Your failure to comply with this condition gives us the right to immediately terminate this offer and our employment relationship with you.

Your continual employment with the Company at all times is strictly “at will.” This means that you may terminate your employment with the Company at any time and for any reason whatsoever, simply by notifying the company. Likewise, the Company may terminate your employment at any time and for any reason whatsoever, with or without cause or advance notice. In case of any such termination, the Company is under no obligation to pay you a severance and the Company shall have no outstanding obligations to you. This at-will employment relationship cannot be changed except in writing, signed by the Chief Executive Officer or General Counsel of the Company.

In the unlikely event of a dispute between the Company and you arising out of or related to your employment, including any matter related to the stock options, or the termination of your employment for any reason whatsoever, we each agree to submit our dispute to binding arbitration in the County of San Mateo, California under the Federal Arbitration Act if we are unable to resolve the dispute after meeting and conferring in good faith within 45 days. This means that there will be no court or jury trial of disputes between us concerning your employment or the termination of your employment. To the extent any such prospective arbitration concerns claims arising out of your employment with the Company, the Company will pay all of the arbitration costs. This agreement to arbitrate is intended to be broad (and covers, for example, claims under state and federal laws prohibiting discrimination on the basis of race, sex, age, disability, family leave, etc.), subject to applicable limitations provided under state law. The agreement to arbitrate shall not be applicable to the enforcement of the PIIA concerning confidential information and ownership of inventions. The terms of your employment will be governed by California law.

Your employment start date shall be 07/5/2016 (the “Start Date”) unless we otherwise mutually agree, and subject at all times to a clear background check and eligibility to work in the United States.
