By electing to exchange my eligible options, I understand and agree to all of the following:

1. I hereby agree to exchange my eligible options for replacement options as indicated on the Election Form in accordance with the terms of the Offer as set forth in the Offer Information Document, dated March 24, 2009, of which I hereby acknowledge receipt. Each eligible option indicated on the Election Form will be cancelled on April 22, 2009 or, if the Offer is extended, on the extended expiration date. A replacement option will be granted to me on April 22, 2009, in accordance with the terms of the Offer or, if the Offer is extended, on the expiration date of the extended Offer.

2. The Offer is currently set to expire at 9:00 p.m. U.S. Pacific Time on April 22, 2009 (7:00 a.m. Israeli Time on April 23, 2009), unless the Company, in its discretion, extends the period of time during which the Offer will remain open.

3. If I cease to be employed or contracted by the Company or its majority owned subsidiary before the Company grants me new options in exchange for my eligible options, I will not receive any new options. Instead, I will keep my current eligible options and they will expire in accordance with their terms.

4. Until 9:00 p.m. U.S. Pacific Time on April 22, 2009 (7:00 a.m. Israeli Time on April 23, 2009), I will have the right to change the elections that I have made with respect to some or all of my eligible options that I elected to exchange or elected not to exchange. HOWEVER, AFTER THAT DATE I WILL HAVE NO ABILITY TO CHANGE MY ELECTION. The last properly submitted election, whether electronically or in paper form, prior to the expiration of the Offer shall be binding. Until the Offer period closes on 9:00 p.m. U.S. Pacific Time on April 22, 2009 (7:00 a.m. Israeli Time on April 23, 2009), I may withdraw my tendered eligible options at any time prior to the Company’s acceptance of such options for exchange pursuant to the Offer.

5. The tender of some or all of my eligible options will constitute my acceptance of all of the terms and conditions of the Offer. Acceptance by the Company of my eligible options pursuant to the Offer will constitute a binding agreement between the Company and me upon the terms and subject to the conditions of the Offer.

6. I am the registered holder of the eligible options tendered hereby, and my name and other information appearing on the Election Form are true and correct.

7. I am not required to tender some or all of my eligible options pursuant to the Offer.

8. THE COMPANY AND/OR ANY INDEPENDENT FIRMS HIRED WITH RESPECT TO THE OFFER CANNOT GIVE ME LEGAL, TAX OR INVESTMENT ADVICE WITH RESPECT TO THE OFFER AND I HAVE BEEN ADVISED TO CONSULT WITH MY OWN LEGAL, TAX AND INVESTMENT ADVISORS AS TO THE CONSEQUENCES OF PARTICIPATING OR NOT PARTICIPATING IN THE OFFER.

9. Under certain circumstances set forth in the Offer Information Document, the Company may terminate or amend the Offer and postpone its acceptance of the eligible options I have elected to exchange. Should the eligible options tendered herewith not be accepted for exchange, such options will continue to be governed by their original terms and conditions.

10. I UNDERSTAND THAT IF I DO NOT CLEARLY MARK THE BOX ELECTING TO EXCHANGE EACH OF MY ELIGIBLE OPTIONS ON THE ELECTION FORM, SUCH ELIGIBLE OPTIONS WILL NOT BE EXCHANGED.

I understand that none of the officers or employees of Mellanox, the Board of Directors of Mellanox or the Compensation Committee of the Board of Directors of Mellanox is making any recommendation as to whether I should exchange or refrain from exchanging my eligible options, and that I must make my own decision whether to tender my eligible options, taking into account my own personal circumstances and preferences. I understand that the replacement options may decline in value when I decide to exercise such options. I further understand that past and current market prices of Mellanox ordinary shares may provide little or no basis for predicting what the market price of Mellanox ordinary shares will be in the event I elect to exchange my options in accordance with the terms of this offer or at any other time in the future.
