Riverbed Technology (RVBD)

CHANGE IN CONTROL SEVERANCE AGREEMENT

This Change in Control Severance Agreement (the “Agreement”) is made and entered into by and between Jerry M. Kennelly (“Executive”) and Riverbed Technology, Inc. (the “Company”), effective as of May 1, 2008 (the “Effective Date”).

RECITALS

1. It is expected that the Company from time to time will consider the possibility of an acquisition by another company or other change in control. The Compensation Committee of the Board of Directors of the Company (the “Committee”) recognizes that such consideration can be a distraction to Executive and can cause Executive to consider alternative employment opportunities. The Committee has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication and objectivity of Executive, notwithstanding the possibility, threat or occurrence of a Change in Control of the Company.

2. The Committee believes that it is in the best interests of the Company and its stockholders to provide Executive with an incentive to continue his employment and to motivate Executive to maximize the value of the Company upon a Change in Control for the benefit of its stockholders.

3. The Committee believes that it is imperative to provide Executive with certain severance benefits upon Executive’s termination of employment following a Change in Control. These benefits will provide Executive with enhanced financial security and incentive and encouragement to remain with the Company notwithstanding the possibility of a Change in Control.

4. Certain capitalized terms used in the Agreement are defined in Section 5 below.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows:
