Re: Amendment to Offer Letter

Dear Clyde,

I am pleased to inform you that on July 24, 2015, the compensation committee of
the board of directors of RingCentral, Inc. amended and restated the first
paragraph of the “Double-Trigger Equity Award Vesting Acceleration” section of
the offer letter between you and RingCentral, Inc., dated August 7, 2013 (the
“Offer Letter”), to provide:

Double-Trigger Equity Award Vesting Acceleration. If the Company consummates a
“Change of Control (defined below) any time after your Start and, (i) you are
terminated by the Company for reasons other than “Cause” (as defined below),
death, or disability within 90 days prior to the Change of Control and/or are
not hired by the surviving / successor entity, or (ii) within 12 months after
the Change of Control, your employment is terminated by the successor/surviving
company for reasons other than Cause, death or disability, or you terminate your
employment with the successor/surviving company for “Good Reason” (defined
below), then one hundred percent (100%) of your unvested stock options and other
equity awards shall immediately vest on the date of the Change of Control or
termination, whichever is later to occur, and, with respect to any stock
options, be exercisable, in accordance with the terms and conditions of the
applicable equity plan and your equity award agreements under which these awards
were granted.

Except as otherwise provided herein, the terms of your Offer Letter remain in
full force and effect. Thank you for your continued contributions to
RingCentral, Inc.

 

Sincerely,
