     o    Program Specifics

     o    Procedures

     o    Important Dates

     o    Questions & Answers




                                                                   [EMCORE LOGO]

 "6 + 1" EXCHANGE PROGRAM

- --------------------------------------------------------------------------------


                       WE ARE PLEASED TO ANNOUNCE THAT THE

                     BOARD OF DIRECTORS HAS APPROVED THE 6+1

                     EXCHANGE PROGRAM FOR EMCORE EMPLOYEES.

o    Board of Directors and Corporate Executive Officers of the Company ARE
     EXCLUDED

o    HOW DOES A "6+1" EXCHANGE PROGRAM WORK?

     -    Cancellation of old options

     -    Wait 6 months and 1 day

     -    Grant new options at THEN current closing prices




                                                                   [EMCORE LOGO]



- --------------------------------------------------------------------------------

 "6 + 1" EXCHANGE PROGRAM

- --------------------------------------------------------------------------------

o    WHY DO THIS?

     -    Stock options are a key element of total compensation, especially in
          our highly competitive technology sector

     -    Many of our outstanding options have exercise prices significantly
          higher than the current market price of our common stock

     -    In order for our stock option program to serve as an effective
          incentive for employee retention, the options must provide an
          opportunity to realize value within a reasonable time period




                                                                   [EMCORE LOGO]





- --------------------------------------------------------------------------------

 THE EMCORE "6+1"
 STOCK OPTION EXCHANGE PROGRAM

     o    All outstanding options with an exercise price of at least $4.00 per
          share are eligible for exchange

     o    Options may be exchanged one-for-one for new options to be issued on
          or about May 1, 2003

     o    During the cancellation period all options exchanged cease to exist




                                                                   [EMCORE LOGO]
