Item 1.01. Entry into a Definitive Material Agreement.

Merger Agreement

On January 30, 2015, Luna Innovations Incorporated, a Delaware corporation (“Luna”), Advanced Photonix, Inc., a Delaware corporation (“API”), and API Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Luna (“Merger Sub”), entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”), pursuant to which Merger Sub will merge with and into API (the “Merger”), with API surviving the Merger as a wholly owned subsidiary of Luna.

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), by virtue of the Merger and without any further action on the part of Luna, API, Merger Sub or any stockholder of the API, each share of the common stock of API, par value $0.001 per share (the “API Common Stock”), will be converted into the right to receive 0.31782 shares of the common stock, par value $0.001 per share, of Luna (the “Luna Common Stock”) (the exchange ratio of one share of API Common Stock for 0.31782 shares of Luna Common Stock, the “Exchange Ratio”). No fractional shares of Luna Common Stock will be issued in the Merger, and holders of shares of API Common Stock will receive cash in lieu of any such fractional shares. Shares of Luna Common Stock will be listed on the Nasdaq Capital Market. In addition, unless otherwise provided by the terms of the warrant, each outstanding warrant to purchase API Common Stock or API’s preferred stock will be converted at the Effective Time into a warrant to purchase Luna Common Stock (based on the Exchange Ratio) and will be assumed by Luna. Each outstanding option to purchase API Common Stock will be converted at the Effective Time into an option to purchase Luna Common Stock (based on the Exchange Ratio) and will be assumed by Luna and each share of API restricted common stock will be converted at the Effective Time into Luna restricted common stock (based on the Exchange Ratio).

Luna and API intend that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code and that the Merger Agreement will qualify as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

The Merger Agreement also provides that, effective at the Effective Time, the board of directors of Luna will be expanded to seven seats and will be composed of three directors designated by Luna's board of directors prior to the Effective Time, who will include Richard W. Roedel, as chairman, John B. Williamson, III and Michael W.Wise, and three directors to be designated by API’s board of directors prior to the Effective Time, who shall include Donald Pastor, Gary Spiegel and Ed J. Coringrato Jr. In addition, the Merger Agreement further provides that Luna’s chief executive officer will continue to serve as Luna’s chief executive officer and as a member of Luna’s board of directors.

API’s board of directors has approved the Merger Agreement and has agreed to recommend that API’s stockholders adopt the Merger Agreement and approve the transactions contemplated thereby. Luna’s board of directors has approved the Merger Agreement and has agreed to recommend that Luna’s stockholders approve the issuance of shares of Luna Common Stock in the Merger.

The Merger Agreement contains customary representations and warranties and pre-closing covenants. During the period from the date of the Merger Agreement to the Effective Time, Luna and API have agreed to carry on their respective businesses in the ordinary course and consistent with past practices and have agreed to certain other operating covenants, as set forth more fully in the Merger Agreement. Luna and API have also agreed not to solicit or engage in discussions with third parties regarding other proposals to acquire Luna and API, respectively, subject to specified exceptions. In addition, the Merger Agreement contains covenants that require each of Luna and API to call and hold special stockholder meetings and, subject to certain exceptions, require API’s board of directors to recommend to API’s stockholders the adoption of the Merger Agreement and approval of the transactions contemplated thereby and Luna’s board of directors to recommend to Luna’s stockholders the approval of the issuance of Luna Common Stock as consideration for the Merger.

The completion of the Merger is subject to the satisfaction or waiver of a number of customary closing conditions in the Merger Agreement, including, among others, the effectiveness of a Form S-4 registration statement to be filed by Luna with the Securities and Exchange Commission (the “SEC”), the adoption of the Merger Agreement and approval of the transactions contemplated thereby by API’s stockholders, approval by Luna’s stockholders of the issuance of shares of Luna Common Stock, the absence of certain governmental restraints and the absence of a material adverse effect on Luna or API.

The Merger Agreement may be terminated by either Luna or API in certain circumstances, including if the Merger has not been consummated on or before August 31, 2015, if the approval of the stockholders of either Luna or API is not obtained and for breaches of certain representations and warranties. If the Merger Agreement is terminated in certain specified circumstances, API must pay Luna, or Luna must pay API, as applicable, a termination fee of $750,000. In addition, if the Merger Agreement is terminated following a meeting of the stockholders of Luna or API at which the adoption of the Merger Agreement and approval of the transactions contemplated thereby, or the approval of the issuance of shares of Luna Common Stock as consideration in the Merger is considered but not approved, then Luna or API, as applicable, will be required to pay an amount up to $250,000 in reimbursement of the other party’s out-of-pocket expenses incurred in connection with the transaction.
