To: Inphi Corporation

I previously received the Offer to Exchange dated September 20, 2012 (the “Offer”) and related documents.

I signed and returned the Election Form, thereby electing to exchange certain of my outstanding eligible stock options listed in the Election Form for replacement options. I now wish to withdraw some or all of my tendered options from the Offer. I understand that by signing this Notice of Withdrawal and delivering it pursuant to the procedure described in Part III, Section 4 of the Offer to Exchange and the instructions above, I will be withdrawing my election with respect to some or all of my outstanding eligible options.

By withdrawing my election, I understand that I will not receive any replacement options for, and will continue to hold, my outstanding eligible options which I withdraw from the Offer, which will continue to be governed by the terms and conditions of the applicable existing stock option agreement(s), including any country-specific appendix, between Inphi Corporation and me.

I understand that if I wish to change this withdrawal of my tendered options and once again accept the Offer for any options that I have withdrawn, I must submit a new signed Election Form prior to the expiration of the Offer.

Please check the appropriate box:

¨ I wish to withdraw my previous election to accept the Offer with respect to my eligible options and instead REJECT the Offer with respect to all of my eligible options. I do not wish to accept the Offer with respect to any of my eligible options.

OR

¨ I wish to withdraw my previous election to accept the Offer with respect to each of the eligible options listed below (and on any additional sheets which I have attached to this Notice of Withdrawal). I still wish to accept the Offer with respect to the rest of the eligible options listed on the election form I previously submitted.

I have completed and signed this Notice of Withdrawal exactly as my name appears on my original Election Form.
