NANO Nanometrics Inc

Item 1.01. Entry into a Material Definitive Agreement.

On June 23, 2019, Nanometrics Incorporated, a Delaware corporation (“Nanometrics” or the “Company”), Rudolph Technologies, Inc., a Delaware corporation (“Rudolph”) and PV Equipment Inc., a Delaware corporation and a wholly owned subsidiary of Nanometrics (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Rudolph, with Rudolph continuing as a wholly owned subsidiary of Nanometrics and the surviving corporation of the merger (the “Merger”). The Merger is intended to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger, each outstanding share of common stock, par value $0.001 per share, of Rudolph (“Rudolph Common Stock”) will be converted into the right to receive 0.8042 (the “Exchange Ratio”) shares of common stock, par value $0.001 per share, of Nanometrics (“Nanometrics Common Stock”). Holders of Rudolph Common Stock will receive cash in lieu of fractional shares. At the effective time of the Merger, Rudolph’s common stockholders will own approximately 50%, and Nanometrics’ common stockholders will own approximately 50%, of the outstanding shares of common stock of the combined company on a fully diluted basis.

In addition, as of the effective time of the Merger, Nanometrics will assume the outstanding Rudolph equity awards granted under Rudolph’s equity compensation plans, with the number of shares underlying such award (and in the case of stock options, the applicable exercise price) adjusted based on the Exchange Ratio, except that Rudolph stock options held by employees whose employment with Rudolph ceases prior to the effective time of the Merger will receive a cash payment equal to the positive difference, if any, calculated by subtracting the aggregate exercise price of such Rudolph stock option from the product of (i) the aggregate number of shares of Rudolph Common Stock subject to such Rudolph stock option and (ii) the Exchange Ratio multiplied by the volume weighted average trading price of shares of Nanometrics Common Stock on the New York Stock Exchange, calculated to four decimal places and determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours, for the five (5) consecutive trading days ending on the third complete trading day prior to (and excluding) the closing date of the Merger as reported by Bloomberg, L.P. (subject to any withholding required by applicable law). Each converted equity award will continue to be subject to the same terms and conditions as applied

to the corresponding Rudolph equity award as of immediately prior to the closing of the Merger, subject to potentially different treatment for awards outside the United States to take into account local laws and employment conditions. Nanometrics’ outstanding equity awards under its equity compensation plans will remain outstanding, subject to the terms of such awards.

Each of Rudolph and Nanometrics has agreed to customary representations, warranties and covenants in the Merger Agreement including, among others, covenants relating to (1) the conduct of their respective businesses during the period between the execution of the Merger Agreement and the effective time of the Merger, (2) non-solicitation of alternative acquisition proposals, (3) Nanometrics’ obligation to call a meeting of its stockholders, and subject to certain exceptions, to recommend that its stockholders approve the issuance of shares of Nanometrics Common Stock and to amend and restate the certificate of incorporation of Nanometrics to increase the number of authorized shares of common stock, (4) Rudolph’s obligations to call a meeting of its stockholders to adopt the Merger Agreement, and subject to certain exceptions, to recommend that its stockholders adopt the Merger Agreement and (5) Nanometrics filing with the Securities and Exchange Commission (the “SEC”) and causing to become effective a registration statement on Form S-4 to register the shares of Nanometrics Common Stock to be issued pursuant to the Merger Agreement (the “Registration Statement”).

Consummation of the Merger is subject to certain closing conditions, including, among other things, the (1) approval by the stockholders of Nanometrics of the issuance of the shares of Nanometrics Common Stock pursuant to the Merger Agreement, (2) approval by the stockholders of Nanometrics of an amendment and restatement of Nanometrics’ certificate of incorporation to increase the number of authorized shares of common stock, (3) the adoption by the stockholders of Rudolph of the Merger Agreement, (4) authorization for listing on the New York Stock Exchange of the shares of Nanometrics Common Stock (including the shares to be issued in the Merger), subject to official notice of issuance, (5) the receipt of required regulatory approvals, (6) effectiveness of the Registration Statement and (7) the absence of any order, injunction, decree or other legal restraint preventing, or any proceeding brought by a governmental authority challenging, the completion of the Merger or making the completion of the Merger illegal. Each party’s obligation to consummate the Merger is also subject to other specified customary conditions, including (1) the representations and warranties of the other party being true and correct as of the date of the Merger Agreement and as of the closing date of the Merger, generally subject to an overall material adverse effect qualification, (2) the performance in all material respects by the other party of its obligations under the Merger Agreement required to be performed on or prior to the date of the closing of the Merger, (3) receipt by such party of an opinion from its counsel of its obligations to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code and (4) the absence of a continuing material adverse effect with respect to the other party.

The Merger Agreement contains certain termination rights for both Rudolph and Nanometrics. Upon termination of the Merger Agreement under specified circumstances, one party may be required to pay the other party a termination fee of $26,000,000.

Nanometrics has agreed to take all action necessary such that, as of the effective time of the Merger, the Board of Directors of the combined company will consist of twelve members, six of whom will be designated by each of Nanometrics and Rudolph, respectively. The parties have also agreed that two of those board members will be Michael P. Plisinski, the Chief Executive Officer of Rudolph, who will become the Chief Executive Officer of the combined company at the effective time of the Merger, and Christopher A. Seams, a member of the Nanometrics Board of Directors, who will become the Chairman of the Board of Directors of the combined company at the effective time of the Merger.

The preceding summary does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and which is incorporated herein by reference. The Merger Agreement has been attached as an exhibit to this Current Report on Form 8-K to provide investors and securityholders with information regarding its terms.

The Merger Agreement includes representations, warranties and covenants of Nanometrics and Rudolph made solely for the purpose of the Merger Agreement and solely for the benefit of the parties thereto in connection with the negotiated terms of the Merger Agreement. Investors should not rely on the representations, warranties and covenants in the Merger Agreement or any descriptions thereof as characterizations

of the actual state of facts or conditions of Nanometrics, Rudolph or any of their respective affiliates. Moreover, certain of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to SEC filings or may have been used for purposes of allocating risk among the parties to the Merger Agreement, rather than establishing matters of fact.
