Explanation of Responses:
(1)	This amount originally represented 30,000 restricted stock units. The number of restricted stock units was subsequently adjusted, pursuant to the terms of the Issuer's 2012 Equity Incentive Plan, to reflect the effect of an equitable and proportional adjustment made in connection with a special cash dividend paid by the Issuer on July 29, 2016.
(2)	The restricted stock units were awarded to the Reporting Person for no cash or other similar consideration.
(3)	Represents the number of shares required to be withheld in accordance with Rule 16b-3 to cover the Reporting Person's tax withholding obligations in connection with the vesting of the restricted stock units reported herein.
(4)	Each restricted stock unit represented a contingent right to receive one share of Emcore common stock. Restricted stock units were payable, at the election of the Issuer, in cash, Emcore common stock, or a combination of the two.
(5)	Not later than 30 days after vesting occurs, vested shares of EMCORE common stock, an amount in cash equal to their fair market value or a combination of the two will be delivered to the Reporting Person.
