(Commission File No. 333-85906)

On August 2, 2002, Avanex Corporation sent an email message from Paul Engle, President and CEO, to all of its employees. The text of the email message follows.

Dear Avanex Employees:

As you are aware, we are in the final stages of completing our merger with Oplink. Stockholder meetings are scheduled for August 15, 2002 to finalize the approval of the merger. Therefore, after these shareholder meetings are successfully concluded, on or about August 19, 2002 we will be a single company.

We continue to face an extremely difficult business environment. Many factors have come to bear on the telecom, telecom equipment, and telecom component markets. While this market is down today, I am confident that it will come back. In the mean time, the strong companies will survive and use this market pause to strengthen their position. The new Avanex, that is the new company coming out of the merger of Avanex and Oplink, will create a stronger competitor, one that has a better opportunity to address the market, both during these troubled times, and as the market recovers. The new company has the potential to be much more valuable to all of its stakeholders, i.e. its customers, employees, and shareholders.

Our objective is clear: to create the new Avanex as a market powerhouse, a leading and winning company we are all proud to be part of. Conducting our business to create exceptional performance and, particularly, serving our customers with the utmost focus to win their favor is and will continue to be our highest priority. We need to continue to excel in our design activities, in getting our new products to market, in winning business, in producing and shipping customer orders on time, in providing the maximum in customer service, and in continuing to demonstrate to our customers that Avanex is indeed a special company.

Once the merger is complete, finalization and execution of the new companies integration plans will be a matter of urgency. Many of you have participated in planning activities for the post merger company. You are aware of the high potential value that the merger brings. This value can only be realized by execution of these plans. The time it takes to successfully integrate our business operations is largely dependant on how quickly and efficiently we can come together and apply the power of all the resources of the combined company towards achieving a common set of goals.

As quickly as possible following the completion of the merger these plans will be finalized and will become actions to build the new Avanex into reality. Employee meetings will be scheduled frequently to insure employees are kept informed as the successful integration of the two companies becomes a very real objective and focus.

One final note. I, along with other officers from Avanex and Oplink, will be presenting our message of the power of the new Avanex to current and potential investors over the next several weeks. I encourage you to view this investor presentation, which is now available on our Avanex web site.

Thank you,

Paul
