     According to our records, you have not yet submitted an Election Form for your eligible options. Participation in the Offer is voluntary; however, if you would like to participate in the Offer, you must complete an Election Form before the expiration of the Offer. Election Forms and other documents relating to the Offer (including instructions) are available on the Offer website at http://portal.yok.mtl.com/system/misc/repricing.php.

     If you are not able to submit your Election Form electronically via the Offer website as a result of technical failures, such as the website being unavailable or the website not accepting your election, or if you do not otherwise have access to the Offer website for any reason (including lack of internet services), a properly signed and completed Election Form must be received by no later than 9:00 p.m. U.S. Pacific Time on April 22, 2009 (7:00 a.m. Israeli Time on April 23, 2009) to Matthew Gloss, Vice President of Legal Affairs, via facsimile at 1 + (408) 970-3403 or via hand delivery to Matthew Gloss, Vice President of Legal Affairs, Mellanox Technologies, Inc., 350 Oakmead Parkway, Suite 100, Sunnyvale, California 94085.

     The submission of the required documents must be made by the deadline indicated above. We cannot accept late submissions, and we therefore urge you to respond early to avoid any last minute problems. If you are unable to, or choose not to submit electronically, only documents that are complete, signed and actually received by Matthew Gloss, Vice President of Legal Affairs, via facsimile at 1 + (408) 970-3403 or via hand delivery to Matthew Gloss, Vice President of Legal Affairs, Mellanox Technologies, Inc., 350 Oakmead Parkway, Suite 100, Sunnyvale, California 94085, by the deadline will be accepted.
