Dear Mark:

It is a pleasure to extend this offer to join EMCORE as the Chief Financial

Executive Officer, Dr. Hong Hou. Your estimated start date will be Monday,
October 11, 2010. Your bi-weekly salary will be $10,000.00, which when
annualized is equivalent to $260,000.00.

Relocation. The offer will provide relocation from Bay Area, California to
Albuquerque, New Mexico. To ensure a smooth transition and provide guidance
through every aspect of your move, EMCORE has teamed with Primacy Relocation,
LLC as our third party relocation partner. We believe that Primacy's relocation
team offers excellent service when it comes to managing the details of your
move, anticipating relocation challenges and recognizing that you and your
family may have special relocation needs.

A Primacy Relocation Consultant will serve as your personal resource throughout
the relocation process. You can expect to be contacted by your Primacy
Relocation Consultant a few days after submitting your Repayment Agreement to
Human Resources. As your point person, this individual will be reachable 24
hours a day in the event that you have an urgent need.

Plan. Your bonus target of 35% is based upon Company-wide performance

the date EMCORE pays the bonus under the Plan in order to qualify for the bonus.

Stock Option Grant. Upon Board Ratification of the 2010 Equity Incentive Plan
documents and full implementation of the Company's 2010 Equity Incentive Plan,
we will recommend to the Board of Directors that you be granted 300,000 stock
options under an Incentive Stock Option Agreement, which will entitle you to
purchase EMCORE stock. Upon approval by the Board of Directors, the options will
be priced at the fair market value (as defined in the EMCORE Corporation 2010
Equity Incentive Plan). Shortly after Board Approval, you will also receive your
formal Incentive Stock Option Agreement (the "Agreement"). Your stock options
vest over five years with the first options vesting on the one-year anniversary
of the grant date and equal amounts thereafter on each anniversary. The terms of
your options, including terms of exercise and expiration, are governed by the
EMCORE Corporation 2010 Equity Incentive Plan (the "Plan") and the Agreement.

The general description above is qualified in all respects by the terms of the
Plan and Agreement. If you have any questions about our stock option program,
