On July 23, 2018, Infinera Corporation, a Delaware corporation (the “Company”), entered into a Unit Purchase Agreement (the “Purchase Agreement”) with Coriant Investor LLC, a Delaware limited liability company (“Seller”) and Oaktree Optical Holdings, L.P., a Delaware limited partnership (“Lender”). Pursuant to the terms of the Purchase Agreement, the Company will purchase from the Seller 100% of the issued and outstanding limited liability company interests (the “Units”) of Telecom Holding Parent LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Seller (such company, “Coriant,” and such purchase, the “Acquisition”).

Pursuant to the terms of the Purchase Agreement, upon consummation of the Acquisition, the Seller shall sell and transfer to the Company, and the Company shall purchase from Seller, all of the Units. In consideration therefore, the Company will pay an aggregate amount of consideration consisting of approximately $230 million in cash and 21 million shares of Company common stock, subject to certain customary adjustments. Substantially all such consideration shall be paid or delivered, as applicable, to the creditors of Coriant and its subsidiaries, including the Lender, in satisfaction of certain obligations owed thereto by such persons. The cash portion of the amounts payable in the Acquisition is expected to be financed with a combination of new debt and cash on the Company’s balance sheet. In connection with its entry into the Purchase Agreement, the Company obtained a commitment from Morgan Stanley Senior Funding, Inc. for a $200 million senior secured bridge facility, subject to customary conditions.

In connection with the signing of the Purchase Agreement, certain key service providers of Coriant have entered into employment and/or consulting arrangements with the Company and its subsidiaries (including, following the closing of the Acquisition, Coriant), to become effective upon the consummation of the Acquisition.

Consummation of the Acquisition is subject to customary closing conditions, including, without limitation, the absence of certain legal impediments, the expiration or termination of the required waiting periods under certain antitrust, competition or other similar laws (including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended) and the performance of certain covenants and agreements.

The Purchase Agreement contains representations, warranties and covenants of the Company, Seller and Lender that are customary for a transaction of this nature, including among others, covenants by the Seller regarding the conduct of Coriant’s business during the pendency of the transactions contemplated by the Purchase Agreement, public disclosures and other matters.

The Acquisition is anticipated to close in the Company’s third fiscal quarter ending September 29, 2018.

The Purchase Agreement contains certain termination rights for both Company and Seller including, for example, (i) the failure to consummate the Acquisition prior to the six-month anniversary of the signing of the Purchase Agreement, (the “Termination Date”), provided that such Termination Date will be automatically extended for three months if matter giving rise to the failure of such condition is related to the approval under the HSR Act or any Foreign Competition Law and (ii) a permanent injunction or order being issued prohibiting the consummation of the Acquisition.

The foregoing description of the Purchase Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Purchase Agreement, which will be subsequently filed. In particular, the assertions embodied in the representations and warranties contained in the Purchase Agreement are qualified by information in a confidential Disclosure Schedule provided by Seller to the Company in connection with the signing of the Purchase Agreement. This confidential Disclosure Schedule contains information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Purchase Agreement. Moreover, certain representations and warranties in the Purchase Agreement were used for the purpose of allocating risk between the Company and Seller rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties in the Purchase Agreement as characterizations of the actual state of facts about the Company or Coriant.
