Item 3.02  Unregistered Sales of Equity Securities

On November 21, 2012, Eric S. Rosenfeld, the Chairman and Chief Executive Officer of Trio Merger Corp. (the “Company”), and one of the Company’s initial stockholders, loaned the Company $100,000. The loan is evidenced by an unsecured promissory note issued to Mr. Rosenfeld. The loan is non interest bearing and is payable at the consummation by the Company of a merger, share exchange, asset acquisition, or other similar business combination, with one or more businesses or entities (a “Business Combination”). Upon consummation of a Business Combination, the principal balance of the note may be converted, at the holder’s option, to warrants at a price of $0.50 per warrant. The terms of the warrants will be identical to the warrants issued by the Company in its initial public offering except that such warrants will be non-redeemable by the Company and will be exercisable for cash or on a “cashless” basis, in each case, if held by the initial holder or its permitted transferees. If Mr. Rosenfeld converts the entire principal balance of the note, he would receive warrants to purchase an aggregate of 200,000 shares of the Company’s common stock. The issuance of the notes to Mr. Rosenfeld was exempt pursuant to Section 4(2) of the Securities Act of 1933, as amended.
