March 6, 2018,

Dear Shareholder:

We recently mailed to you a proxy statement of Cavium, Inc. (“Cavium”). Your support is requested for the proposals to be voted upon at the special meeting of shareholders of Cavium to be held on March 16, 2018.    As of the date of this letter your shares of Cavium remain unvoted.

The Cavium board of directors unanimously recommends that shareholders vote “FOR” each of the proposals being submitted to a vote at the Cavium special meeting of shareholders.

Please Vote Your Cavium Shares Today!

Regardless of the number of shares you own your vote is very important. We encourage all shareholders to have their voices heard. The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Cavium common stock entitled to vote on the proposal. Failure to vote and a vote to abstain will have the same effect as a vote against the proposal to adopt the merger agreement and thereby approve the merger.

There are three ways to vote your shares of Cavium without attending the special meeting of shareholders in person – each only taking a few moments:

 

    By Telephone – Shareholders in the United States can submit their vote by calling the toll-free number indicated on the enclosed vote instruction form; please have your control number located on the enclosed vote instruction form available when calling;

 

    By Internet – Shareholders can submit their vote via internet at www.proxyvote.com; please have the control number located on the enclosed vote instruction form available; or

 

    By Mail – Shareholders can vote by mail by signing, dating and returning the enclosed vote instruction form in the postage-paid envelope provided.

To be valid, your vote by telephone or internet must be received by 11:59 p.m. (Eastern Time) on March 15, 2018, the day preceding the special meeting of shareholders.

If you need assistance in voting your shares or have questions regarding the special meeting of shareholders, please contact Cavium’s proxy solicitor, MacKenzie Partners, Inc., at (800) 322-2885 (toll-free) or (212) 929-5500 (collect), or email at proxy@mackenziepartners.com.

We thank you for your continued support of Cavium.

Sincerely,

Cavium, Inc.
