Merger Agreement

On August 25, 2017, the Issuer, entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Issuer, Littelfuse, Inc., a Delaware corporation (“Littelfuse”), and Iron Merger Co., Inc., a Delaware corporation and wholly owned subsidiary of Littelfuse (“Merger Sub”), pursuant to which Littelfuse will acquire all of the outstanding shares of Common Stock of the Issuer, in exchange for a combination of cash and shares of common stock, par value $0.01 per share, of Littelfuse (each, a “Littelfuse Common Share”).

Pursuant to the terms of the Merger Agreement, Merger Sub will merge with and into the Issuer (the “Initial Merger”), with the Issuer continuing as the surviving corporation in the Initial Merger and a wholly owned subsidiary of Littelfuse. Further to the terms of the Merger Agreement, the Issuer, as the surviving corporation of the Initial Merger, will merge with and into Littelfuse (the “Follow-On Merger”, and collectively with the Initial Merger, the “Mergers”), with Littelfuse continuing as the surviving corporation in the Follow-On Merger. The respective boards of directors of the Issuer and Littelfuse have unanimously approved the Merger Agreement, the Mergers and the other transactions contemplated by the Merger Agreement.

Upon the terms and subject to the conditions of the Merger Agreement, at the effective time of the Initial Merger (the “Effective Time”), each share of Common Stock of the Issuer issued and outstanding immediately prior to the Effective Time (other than Common Stock held in treasury or owned by Littelfuse or Merger Sub and any Common Stock held by stockholders who properly comply in all respects with the provisions of Section 262 of the General Corporation Law of the State of Delaware as to appraisal rights) will be cancelled and extinguished and automatically converted into the right to receive, at the election of the holder thereof, and subject to proration as described below, (i) $23.00 per share in cash (subject to applicable withholding tax), without interest or (ii) 0.1265 Littelfuse Common Shares.

The foregoing description of the Merger Agreement is only a summary, does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement filed as an exhibit to this Schedule 13D and incorporated herein by reference.

Voting Agreement

Concurrently with the execution of the Merger Agreement, the Reporting Persons entered into a letter agreement with Littelfuse (the “Voting Agreement”) with respect to all shares of Common Stock the Reporting Persons own of record or beneficially and have the power to vote (excluding any shares underlying options exercisable for, or warrants to purchase, shares of Common Stock whether or not such shares are included as beneficially owned by the Reporting Persons in the Company’s most recent annual proxy statement) as of the date of the Voting Agreement (the “Voting Agreement Shares”).

Under the Voting Agreement, the Reporting Persons agreed, among other things, to vote the Voting Agreement Shares (a) in favor of (i) adoption of the Merger Agreement and (ii) any other matter that is required be approved by the stockholders of the Issuer to consummate the transactions contemplated by the Merger Agreement, (b) against (i) any proposal made in opposition to approval of the Merger Agreement and (ii) any competing offer or proposal from any person other than Littelfuse and (c) in favor of any postponement, recess or adjournment at any meeting of the stockholders of the Issuer relating to any matter set forth in (a) or (b).
