Item 1.01. Entry into a Material Definitive Agreement.

On January 7, 2015, West Corporation, a Delaware corporation (the “Company”), entered into an Asset Contribution and Equity Purchase Agreement (the “Purchase Agreement”) with Alorica Inc., a California corporation (“Buyer”), pursuant to which the Company agreed to sell to Buyer several of its agent services businesses (the “Business”) upon the terms and subject to the conditions set forth in the Purchase Agreement (the “Transaction”). The Transaction will be effected through the sale of the outstanding equity interests of certain direct and indirect subsidiaries of the Company (collectively, the “Company Group”), as well as the contribution of certain assets and associated liabilities to the Company Group prior to the closing of the Transaction (the “Closing”). The Transaction is expected to close during the first quarter of 2015, subject to the satisfaction or waiver of various closing conditions, as described below.

At the Closing, Buyer will pay an aggregate purchase price of $275 million in cash, subject to a customary post-closing adjustment based on working capital of the Business (the “Purchase Price”). The Closing is subject to customary closing conditions, including, among others, (a) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (b) absence of legal proceedings instituted by governmental bodies in certain jurisdictions seeking to restrain, prohibit or otherwise challenge the legality or validity of the Transaction, (c) absence of court orders by a governmental body prohibiting or making illegal the Transaction and (d) receipt of approvals from specified governmental bodies.

The Purchase Agreement may be terminated (a) by the mutual consent of the Company and Buyer, (b) by either party in the event of an uncured material breach by the other party or (c) by either the Company or Buyer (i) in the event of the issuance of a final, nonappealable order of a governmental body prohibiting or making illegal the Transaction or (ii) if the Closing has not occurred prior to April 30, 2015 (the “Termination Date”), unless the only conditions remaining to be satisfied are receipt of competition or other governmental approvals, in which case the Termination Date may be extended by either party for an additional period not to exceed 60 days.

The Purchase Agreement contains customary representations, warranties, covenants and other provisions as set forth therein, including certain indemnification obligations. Representations and warranties of the parties generally will survive for 18 months after the Closing, subject to certain exceptions. The Company has agreed to a customary non-solicitation covenant relating to specified employees of Buyer for a period of two years after the Closing and a customary noncompetition covenant for a period of three years after the Closing, in each case subject to certain exceptions set forth in the Purchase Agreement. Buyer has agreed to customary non-solicitation covenants relating to specified employees of the Company and specified customers of the Company for a period of two years after the Closing, in each case subject to certain exceptions set forth in the Purchase Agreement.

In connection with the entry into the Purchase Agreement, Buyer has received financing commitments for a credit facility that may be used by Buyer to fund a portion of the Purchase Price. Buyer’s ability to obtain this or other financing is not a condition to the Closing.

In connection with the Transaction, the Company and Buyer (or their applicable affiliates) will enter into certain ancillary agreements, including, among others, a transition services agreement, licenses with respect to specified intellectual property used in the Business and not being acquired by Buyer and lease or license agreements with respect to certain real properties.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which is attached hereto as Exhibit 2.1 and incorporated herein by reference.
