Item 1.01

Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On February 20, 2019, Immune Design Corp., a Delaware corporation (the “Company” or “Immune Design”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Merck Sharp & Dohme Corp., a New Jersey corporation (“Parent”), and Cascade Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”). The board of directors of the Company has unanimously approved the Merger Agreement.

Pursuant to the Merger Agreement, upon the terms and subject to the conditions thereof, Purchaser will commence a tender offer (the “Offer”) no later than March 6, 2019, to acquire all of the outstanding shares of common stock of the Company, $0.001 par value per share (the “Shares”), at a purchase price of $5.85 per Share in cash (the “Offer Price”), without interest and subject to any required withholding of taxes.

The obligation of Purchaser to purchase Shares tendered in the Offer is subject to the conditions set forth in the Merger Agreement, including that the number of Shares validly tendered in accordance with the terms of the Offer and not validly withdrawn, when considered together with all other Shares (if any) otherwise beneficially owned by Parent or any of its wholly owned subsidiaries (including Purchaser), would represent one more than 50% of the total number of Shares outstanding at the time of the expiration of the Offer (the “Minimum Condition”). The Purchaser’s obligation to consummate the Offer is not subject to a condition that any financing be received by Purchaser for the consummation of the transactions contemplated by the Merger Agreement.

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 a wholly owned subsidiary of Parent (the “Merger”). Purchaser will effect the Merger after consummation of the Offer pursuant to Section 251(h) of the Delaware General Corporation Law. At the effective time of the Merger (the “Effective Time”), the Shares not purchased pursuant to the Offer (other than Shares held by Parent, Purchaser, any other direct or indirect wholly owned subsidiary of Parent, the Company (or in the Company’s treasury) or by stockholders of the Company who have perfected their statutory rights of appraisal under Delaware law) will each be converted into the right to receive an amount in cash equal to the Offer Price (the “Merger Consideration”), without interest and subject to any required withholding of taxes.

Each of the Company’s stock options (the “Company Options”) that is outstanding as of immediately prior to the Effective Time shall accelerate and become fully vested and exercisable effective immediately prior to, and contingent upon, the Effective Time. As of the Effective Time, by virtue of the Merger and without any further action on the part of the holders thereof, Parent, Purchaser or the Company, each Company Option that is then outstanding and unexercised as of immediately before the Effective Time shall be cancelled and converted into the right to receive cash in an amount equal to the product of (i) the total number of Shares subject to such fully vested Company Option immediately prior to the Effective Time, multiplied by (ii) the excess, if any, of (x) the Merger Consideration over (y) the exercise price payable per Share under such Company Option. No holder of a Company Option that has an exercise price per Share that is equal to or greater than the Merger Consideration shall be entitled to any payment with respect to such cancelled Company Option before or after the Effective Time.

Each of the Company’s restricted stock unit awards (the “Company RSU Awards”) that is outstanding as of immediately prior to the Effective Time shall accelerate and become fully vested effective immediately prior to, and contingent upon, the Effective Time. In lieu of any issuance of Shares in settlement of such vested Company RSU Award, as of the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Purchaser, the Company, the holder of such Company RSU Award or any other Person, each Company RSU Award that is outstanding shall be automatically cancelled and converted into the right to receive the Merger Consideration in respect of each Share subject to such Company RSU Award, less applicable withholding obligations.

The Merger Agreement includes representations, warranties and covenants of the parties customary for a transaction of this nature. From the date of the Merger Agreement until the earlier of the Effective Time and the termination of the Merger Agreement, the Company has agreed to operate its business in the ordinary course and has agreed to certain other operating covenants, as set forth more fully in the Merger Agreement. The Company has also agreed not to solicit or initiate discussions with any third party regarding acquisition proposals.

The Merger Agreement includes a remedy of specific performance for the Company, Parent and Purchaser. The Merger Agreement also includes customary termination provisions for both the Company and Parent and provides that, in connection with the termination of the Merger Agreement under specified circumstances, including termination by the Company to accept and enter into a definitive agreement with respect to an unsolicited superior offer, the Company will be required to pay a termination fee of an amount in cash equal to $10.5 million (the “Termination Fee”). Any such termination of the Merger Agreement by the Company is subject to certain conditions, including the Company’s compliance with certain procedures set forth in the Merger Agreement and a determination by the board of directors of the Company that the failure to take such action would be inconsistent with the board’s fiduciary duties to the Company’s stockholders under applicable law, payment of the Termination Fee by the Company and the execution of a definitive agreement by the Company with such third party.

Item 8.01

Other Events.

On February 21, 2019, the Company and Merck & Co., Inc. issued a joint press release announcing the execution of the Merger Agreement as described above. A copy of the press release is attached as Exhibit 99.1 and incorporated herein by reference.

Additional Information

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to this report and incorporated herein by reference.

The Merger Agreement and the foregoing description of such agreement has been included to provide investors and stockholders with information regarding the terms of such agreement. The assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by information in confidential disclosure schedules delivered by the Company to Parent and Purchaser in connection with the signing of the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement were made as of a specified date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for the purpose of allocating risk between the parties to the Merger Agreement. Accordingly, the representations and warranties in the Merger Agreement should not be relied on by any persons as characterizations of the actual state of facts and circumstances of the Company at the time they were made and should consider the information in the Merger Agreement in conjunction with the entirety of the factual disclosure about the Company in the Company’s public reports filed with the SEC. Information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.
