E-MAIL TO OPTION HOLDERS

July 19, 2002

To Multilink Option Holders Located in the United States and Europe:

As you know, on June 24, 2002, Multilink Technology Corporation (“Multilink”) commenced an Option Exchange Program. I am now pleased to announce that the Multilink Board of Directors has decided to revise the Program in several important respects. Most importantly, option holders will now be able to exchange options with an exercise price of $1.35 or more, rather than just those options with an exercise price of $3.90 or more. Second, we are extending the expiration date of the Program from July 23, 2002 to August 30, 2002. Third, although the replacement options will still be granted on the first business day that is at least six months and one day after the expiration date of the offer, based on the new schedule we expect that the grant date will be March 3, 2003 rather than January 24, 2003. Also, all employees who are on a leave of absence on the date that the replacement options are granted (not just those employees who are on a leave of absence that is “protected by statute”), will have the right to receive their replacement options on the grant date, rather than on the date that they return to regular employment with the Company. Finally, we changed the provisions of the offer relating to what happens if we are acquired by another company after your tendered options are accepted for exchange and canceled, but before replacement options are granted. Such consequences are outlined in question 37 on page 8 of the Amended and Restated Offer to Exchange.

There are also several other changes to the Offer, and we encourage you to carefully review the revised Offer to Exchange that is being provided to you to have a more complete understanding of the revised terms.

Under the revised Program, which is entirely voluntary, eligible employees and members of our Board of Directors will have the right to exchange options to purchase Class A common stock with an exercise price equal to or greater than $1.35 per share for new options covering the same number of shares. The new options will be granted on or after March 3, 2003 and will have an exercise price equal to the fair market value of our Class A common stock on the date of grant. Please carefully review the materials referenced below as they will provide you with details on how the Program operates.

If you decide to participate in the Program, you will need to complete and deliver an Election Form (item #2 below) by August 30, 2002 at 12:00 Midnight, Eastern Time, to Multilink Stock Administration located at 300 Atrium Drive, 2nd Floor, Somerset, New Jersey 08773, via personal delivery, interoffice mail or facsimile at (732) 537-3727.
