EXHIBIT 10.1

EXHIBIT E
LOCK-UP AGREEMENT
Concurrently with the execution of this Lock-up Agreement (the “Agreement”), The
Resilience Fund IV, L.P., a Delaware limited partnership and The Resilience Fund
IV-A, L.P., a Delaware limited partnership (collectively, the “Sellers”),
Aerospace Newco Holdings, Inc., a Delaware corporation (“Holdings”), Systron
Donner Inertial, Inc., a Delaware corporation, EMCORE Corporation, a New Jersey
corporation (“Parent”) and Ember Acquisition Sub, a Delaware corporation and a
wholly-owned subsidiary of Parent (“Parent Sub”) are entering into a Purchase
and Sale Agreement (the “Purchase Agreement”) pursuant to which Parent Sub will
purchase the 100% of the outstanding equity securities of Holdings from Sellers
(the “Purchase”) in exchange for a combination of cash and shares of common
stock, no par value, of Parent (the “Common Stock”). Capitalized terms used but
not defined herein shall have the respective meanings assigned to them in the
Purchase Agreement.
Sellers hereby agree that, without the prior written consent of Parent, Sellers
will not, during the period commencing on the date hereof and ending one year
after the Closing (the “Restricted Period”), (1) offer, pledge, sell, contract
to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”)), pursuant to the Purchase
Agreement by the Sellers or any other securities so owned on the date of this
Agreement convertible into or exercisable or exchangeable for Common Stock, or
(2) enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of the Common Stock,
whether any such transaction described in clause (1) or (2) above is to be
settled by delivery of Common Stock or such other securities, in cash or
otherwise or publicly disclose the intention to engage in a transaction
described in (1) or (2) above. The foregoing sentence shall not apply to a bona
fide third-party tender offer, merger, consolidation or other similar
transaction made to all holders of the Common Stock involving a change of
control of the Parent that occurs after the date of the Closing and that has
been approved by the Parent’s board of directors, provided that in the event
that such tender offer, merger, consolidation or other such transaction is not
completed, the Sellers’ securities which are subject to this Agreement shall
continue to be subject to the provisions of this Agreement. For purposes of this
clause (i), a “change of control” means the transfer (whether by tender offer,
merger, consolidation or other similar business combination transaction), in one
transaction or a series of related transactions, to a person or group of
affiliated persons theretofore not affiliates of the Parent, of the Common
Stock, where such person or group did not hold, immediately prior to such
transfer, and, immediately after such transfer, would hold, a majority of the
outstanding voting securities of the Parent (or the surviving entity, if not the
Parent).
The Sellers also agree and consent to the entry of stop transfer instructions
with the Parent’s transfer agent and registrar against the transfer of the
Sellers’ shares of Common Stock except in compliance with the foregoing
restrictions.
The Sellers understand that the Parent is relying upon this Agreement in
proceeding toward consummation of the Purchase. The Sellers further understand
that this Agreement is irrevocable and shall be binding upon the Sellers’ legal
representatives, successors and assigns.

This Agreement and any claim, controversy or dispute arising under or related to
this Agreement shall be governed by and construed in accordance with the laws of
the State of Delaware, without regard to the conflict of laws principles
thereof.
