Item 1.01    Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On June 12, 2014, OpenTable, Inc., a Delaware corporation (the “Company”), The Priceline Group Inc., a Delaware corporation (“Parent”), and Rhombus, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”), entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Parent, through Purchaser, will commence an offer (the “Offer”) to acquire all of the outstanding shares of the Company’s common stock, par value $0.0001 per share (the “Shares”), for $103.00 per share net to the seller in cash, without interest (the “Offer Price”).

Completion of the Offer is subject to several conditions, including (i) that a majority of the Shares outstanding (determined on a fully diluted basis) be validly tendered and not validly withdrawn prior to the expiration of the Offer; (ii) the expiration or termination of any applicable waiting period relating to the Offer under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”); (iii) the absence of a material adverse effect on the Company; and (iv) certain other customary conditions.

Following the completion of the Offer and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Purchaser will merge with and into the Company, with the Company surviving as an indirect wholly owned subsidiary of Parent, pursuant to the procedure provided for under Section 251(h) of the General Corporation Law of the State of Delaware without any stockholder approvals (the “Merger”).

At the effective time of the Merger (the “Effective Time”), by virtue of the Merger and without any action on the part of the holders of any shares of common stock of the Company, each outstanding share of common stock of the Company (other than (i) any shares owned directly by Parent or Purchaser or held in the treasury of the Company or its subsidiaries, or (ii) any shares as to which the holder thereof is entitled to and who properly exercises appraisal rights under Delaware law) will be canceled and converted into the right to receive an amount in cash equal to the Offer Price. In addition, Parent will assume all unvested options to purchase shares of the Company’s common stock (“Company Options”) and all restricted stock units. All vested Company Options will be cashed out at the effective time of the Merger.

Parent and the Company have made customary representations, warranties and covenants in the Merger Agreement, including covenants (i) to promptly as reasonably practicable effect all registrations, filings and submissions required pursuant to the HSR Act and any other required governmental approvals, the Securities Exchange Act of 1934, as amended, and other applicable laws; and (ii) to use reasonable best efforts to consummate and make effective the transactions contemplated by the Merger Agreement as promptly as practicable. The Company has agreed to conduct its business in all material respects in the ordinary course consistent with past practice, including not taking certain specified actions, prior to consummation of the Merger.

The Company has also agreed (i) to cease and terminate all existing, and agreed not to engage or participate in any additional, discussions with third parties regarding alternative proposals for the acquisition of the Company and (ii) not to solicit, initiate or knowingly encourage any inquiry, expression of interest, proposal or offer that constitutes or that would reasonably be expected to result in an alternative proposal for the acquisition of the Company.  However, subject to the satisfaction of certain conditions, the Company and its board of directors, as applicable, are permitted to take certain actions which may, as more fully described in the Merger Agreement, include changing the board of directors’ recommendation following receipt of an unsolicited proposal, if the board of directors of the Company has concluded in good faith after consultation with its outside counsel that such failure to do so would be inconsistent with the fiduciary duties owed by the board of directors to the stockholders of the Company under Delaware law. In addition, the board of directors of the Company is permitted to change its recommendation, for reasons not related to the receipt of an unsolicited proposal, if the board of directors has concluded in good faith, after consultation with the Company’s outside counsel, that the failure to make such change in recommendation would be inconsistent with the fiduciary duties owed by the board of directors to the stockholders under Delaware law.

The Merger Agreement can be terminated by Parent or the Company under certain circumstances, and the Company will be required to pay Parent a termination fee of $91 million in connection with certain terminations.

2

The Merger Agreement has been unanimously adopted by the board of directors of the Company and the board of directors of the Company unanimously recommends that stockholders of the Company tender their Shares in the Offer.

The foregoing description of the Offer, the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached hereto as Exhibit 2.1. The Merger Agreement has been incorporated herein by reference to provide information regarding the terms of the Merger Agreement and is not intended to modify or supplement any factual disclosures about the Company, Parent or Purchaser in any public reports filed with the U.S. Securities and Exchange Commission by the Company or Parent. In particular, the assertions embodied in the representations, warranties and covenants contained in the Merger Agreement were made only for the purposes of the Merger Agreement, were solely for the benefit of the parties to the Merger Agreement, and may be subject to limitations agreed upon by the contracting parties, including being qualified by information in confidential disclosure schedules provided by the Company to Parent in connection with the signing of the Merger Agreement. These disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement. Moreover, the representations and warranties in the Merger Agreement were used for the purpose of allocating risk between the Company, Parent and Purchaser, rather than establishing matters of fact. Accordingly, the representations and warranties in the Merger Agreement may not constitute the actual state of facts about the Company, Parent or Purchaser. The representations and warranties set forth in the Merger Agreement may also be subject to a contractual standard of materiality different from that generally applicable to investors under federal securities laws. Therefore, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the parties or their respective businesses.

Tender Support Agreement

On June 12, 2014, in connection with the Offer, each of Matthew Roberts, I. Duncan Robertson, Michael Dodson, Joseph Essas, A. George “Skip” Battle, J. William Gurley, Robert Hohman, Thomas Layton, Daniel Meyer and Paul Pressler (together, the “Supporting Stockholders”), solely in his capacity as a stockholder or optionholder of the Company, entered into a Tender Support Agreement with Parent and Purchaser (the “Tender Support Agreement”). Under the terms of the Tender Support Agreement, the Supporting Stockholders have agreed, among other things, to tender all Shares now held or hereafter acquired by them in the Offer.  As of June 11, 2014, the Supporting Stockholders beneficially owned or had the option to acquire a number of shares of common stock of the Company equal to approximately 7% of the outstanding shares of common stock of the Company.

The foregoing provisions of the Tender Support Agreement terminate in the event that the Merger Agreement is terminated in accordance with its terms.

The foregoing description of the Tender Support Agreement does not purport to be complete and is qualified in its entirety by reference to the Tender and Support Agreement, the form of which is attached hereto as Exhibit 2.2 and is incorporated herein by reference.

Item 8.01              Other Events.

On June 13, 2014, the Company issued a joint press release with Parent relating to the Merger Agreement. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
