Item 1.01 Entry into a Material Definitive Agreement
Merger Agreement Amendment
On March 23, 2017, American DG Energy Inc. (the "Company") entered into Amendment Number One ("Amendment No. 1") of the Agreement and Plan of Merger, dated on November 1, 2016 (the "Merger Agreement"), by and among Tecogen Inc., a Delaware Corporation ("Tecogen") and Tecogen.ADGE Acquisition Corp., a Delaware Corporation that is a wholly owned subsidiary of Tecogen ("Merger Sub").
Pursuant to Amendment No. 1, article two of the Merger Agreement was amended to add a new section, section 2.7 to describe how outstanding warrants of the Company will be treated in the merger. The parties agreed that all outstanding Company warrants at the time the merger becomes effective, will become exercisable for 0.0920 shares of Tecogen common stock.
Amendment No 1., also amended the definitions of ADGE Stockholder Approval and Tecogen Stockholder Approval.  ADGE Stockholder Approval now means the affirmative vote of the holders of a majority of the issued and outstanding shares of ADGE common stock that is entitled to vote at the ADGE stockholder meeting that vote in favor of the adoption of the Merger Agreement. Tecogen Stockholder Approval means the affirmative vote of the holders of shares of stock having a majority in voting power of the votes cast by the holders of all of the shares of stock present or represented by proxy at the meeting that vote in favor of approval of the issuance of the shares of Tecogen common stock pursuant to the Merger Agreement.
Lastly, Amendment No 1. amended section 6.1 of the Merger Agreement by deleting the section and replacing it. The new section 6.1 states that ADGE Stockholder Approval and Tecogen Stockholder approve will have to be duly obtained to effectuate the merger.
The foregoing descriptions are qualified by their entirety by reference to the full text of the Amendment No. 1 and the Merger Agreement attached hereto respectively as Exhibit 2.1 and 2.2, and incorporated herein by reference.
