Amendment to the Credit Agreement with Wells Fargo Bank, National Association

On December 3, 2014, EMCORE Corporation (the “Company”), a New Jersey corporation, and Wells Fargo Bank, National Association (“Wells Fargo”) entered into a Sixth Amendment (the “Amendment”) to that certain Credit and Security Agreement, dated November 11, 2010, by and between the Company and Wells Fargo (the “Credit Agreement”).

The Amendment amends the provisions of the Credit Agreement prohibiting certain transfers in order to permit the transfer of certain of the Company’s assets pursuant to each of (i) that certain Asset Purchase Agreement, dated as of September 17, 2014, as amended, by and between the Company and SolAero Technologies Corp. (f/k/a Photon Acquisition Corporation), a Delaware corporation (“SolAero” and, such agreement, the “Space Purchase Agreement”), and (ii) that certain Asset Purchase Agreement, dated as of October 22, 2014, by and between the Company and NeoPhotonics Corporation, a Delaware corporation (the “Telecom Purchase Agreement”, together with the Space Purchase Agreement, the “Permitted Agreements” and, the transactions contemplated by the Permitted Agreements, the “Transactions”), in each case, subject to the receipt by the Company of specified proceeds upon the closing of each Transaction, as more fully described in the Amendment. Simultaneous with the closing of each of the Transactions, Wells Fargo has agreed, on the terms and subject to the conditions in the Amendment, to automatically release all of its encumbrances covering the assets transferred pursuant to such transaction.

In addition, the Amendment provides that, upon notice to Wells Fargo of the closing of the transactions contemplated by the Space Purchase Agreement (the “Space Transaction”), the maximum borrowing allowed under the Credit Agreement will be reduced from $35.0 million to $15.0 million and certain other changes to the borrowing base calculations will go into effect.

The execution and delivery of the Amendment is a joint closing condition in the Space Purchase Agreement. The Company’s receipt of consent from Wells Fargo to the transactions contemplated by Telecom Purchase Agreement and release of Wells Fargo’s security interest in the assets transferred pursuant to the Telecom Purchase Agreement, each included in the Amendment, is a joint closing condition of the Telecom Purchase Agreement.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment filed herewith as Exhibit 10.1 and incorporated herein by reference.
