As to all matters of fact, we have relied upon the representations and statements of fact made in the documents so reviewed, and we have not independently established the facts so relied on. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

Please be advised that we have reached the following conclusions regarding the offering:

1.                  The Company is a duly and legally organized and existing Georgia state corporation, with its registered office located and principal place of business located at 2690 Cobb Parkway, Unit A5-284, Atlanta, Georgia 30080. The Certificate of Formation and the Articles of Incorporation with registration fees were submitted to the Georgia Secretary of State and filed with the office on October 19, 2012.

paid for and non-assessable. The common stock to be sold under this Form S-1 Registration Statement is likewise legal under the laws of the State of Georgia, its Constitution and reported judicial decisions interpreting those laws. The shares of common stock to be sold under this Form S-1 Registration statement, as issued, have been duly authorized, fully-paid for and are non-assessable.

3.                  To my knowledge, the Company is not a party to any legal proceedings nor are there any judgments against the Company, nor are there any actions or suits filed or threatened against it or its officers and directors, in their capacities as such, other than as set forth in the registration statement. I have not been made aware of any disputes involving the Company and the Company has no claim, actions or inquires from any federal, state or other government agency, other than as set forth in the registration statement. I have not been made aware of any claims against the Company or any reputed claims against it at this time, other than as set forth in the registration statement.

4.                  The Company’s outstanding shares are all common shares. There are no liquidation preference rights held by any of the Shareholders upon voluntary or involuntary liquidation of the Company.

5.                  The directors and officers of the Company are indemnified against all costs, expenses, judgments and liabilities, including attorney’s fees, reasonably incurred by or imposed upon them or any of them in connection with or resulting from any action, suit or proceedings, civil or general, in which the officer or director is or may be made a party by reason of being or having been such a director or officer. This indemnification is not exclusive of other rights to which such director or officer may be entitled as a matter of law.

6.                  All tax benefits to be derived from the Company’s operations shall inure to the benefit of the Company. Shareholders will receive no tax benefits from their stock ownership, however, this must be reviewed in light of the Tax Reform Act of 1986.

7.                  By directors’ resolution, the Company has authorized the Registration on Form S-1 of 27,526,000 shares of common stock to be offered for sale by the Company and selling shareholders.

The Company’s Articles of Incorporation presently provide the authority to the Company to issue 490,000,000 shares of common stock, with a par value of $0.0001 per share, and 10,000,000 shares of preferred stock, with no par value. Therefore, a Board of Directors’ Resolution which authorized the issuance for sale of up to 27,526,000 shares of common stock is within the authority of the Company’s directors and the shares. The shares of common stock to be sold under this Form S-1 Registration statement, as issued, have been duly authorized, fully-paid for and are non-assessable.
