On April 9, 2015, LinkedIn Corporation, a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with lynda.com, Inc., a Delaware corporation (“lynda.com”), Harpo Acquisition Merger Corporation, a Delaware corporation and wholly-owned subsidiary of the Company (“Sub I”), Harpo Acquisition Merger LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company (“Sub II”, and together with Sub I, the “Merger Subs”) and Shareholder Representative Services LLC, a Colorado limited liability company, as Stockholder Representative.

The Merger Agreement provides for the merger of Sub I with and into lynda.com (the “First Merger”), with lynda.com surviving the Merger as a wholly-owned subsidiary of the Company. As part of the same overall transaction, lynda.com shall merge with and into Sub II (the “Second Merger”; together with the First Merger, the “Mergers”), and Sub II shall be the surviving entity.

The aggregate consideration payable in exchange for all of the outstanding equity interests of lynda.com is approximately $1.5 billion, comprising an aggregate of approximately $780 million in cash and approximately $720 million in the Company’s Class A common stock (the “Stock Consideration”). The consideration is subject to an adjustment based on (i) purchase price adjustment provisions and (ii) indemnification obligations of lynda.com securityholders after the closing of the acquisition. A portion of the consideration will be placed in escrow to satisfy certain indemnification obligations of lynda.com securityholders described in the Merger Agreement.

The Merger Agreement also includes registration rights whereby the Company will file a registration statement on Form S-3 with the Securities and Exchange Commission covering the resale of the Stock Consideration within 60 days of the closing, subject to the terms and conditions of the Merger Agreement.

The Merger Agreement contains customary representations, warranties and covenants by the Company, lynda.com and the Merger Subs. The closing of the Mergers is subject to customary closing conditions, including the expiration or termination of any waiting periods applicable to the consummation of the First Merger under applicable antitrust and competition laws.
