NOW, THEREFORE, in consideration of the mutual agreements and covenants herein contained, the Company, Holdings, and Merger Sub hereby agree as follows:

1. Merger.

(a) At the Effective Time and in accordance with this Agreement and permitted by NRS 92A.134, Merger Sub shall be merged with and into the Company (the “Merger”), and the Company shall be the surviving corporation (hereinafter sometimes referred to as the (“Surviving Corporation”)). At the Effective Time, the separate corporate existence of Merger Sub shall cease, and the Company shall become a wholly-owned subsidiary of Holdings, and Holdings shall become the publicly traded company and the successor issuer to the Company.

(b) The Parties intend that the Merger, together with the Equity Contribution and Restructuring Conversion, qualify as a “reorganization” within the meaning of Section 368(a)(1)(F) of the Code, and hereby adopt this Agreement as a “plan of reorganization” within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3 and Section 354(a)(1) of the Code. The Parties hereto agree to report such transactions in a manner consistent with such treatment on all relevant tax returns

2. Closing; Effective Time. As soon as practicable on or after the date hereof, the Surviving Corporation shall file this Agreement with the Articles of Merger in accordance with the relevant provisions of the NRS, and with the Secretary of State of the State of Nevada (the “Secretary of State”), and shall make all other filings or recordings required under the NRS, if any to effectuate the Merger.

The vesting of such rights, title, liabilities, and obligations in the Surviving Corporation shall not be deemed to constitute an assignment or an undertaking or attempt to assign such rights, title, liabilities and obligations. The conversion of securities of the Company into the identical and equivalent securities of Holdings will not constitute a sale, resale or different security. Securities of Holdings will be of the same class evidencing the same proportional interest of the stockholders in the holding company as they held in the Company, and the rights and interests of the stockholders of such securities are identical to those they possessed as stockholders of the Company’s securities. Immediately following the merger, Holdings has no significant assets other than equity interests of the Company and its existing subsidiary(s) and has the same assets and liabilities on a consolidated basis as the Company had before the merger.
