Ladies and Gentlemen:

As counsel for EnerJex Resources, Inc., a Nevada corporation (the “Company”), we have been requested to render this opinion in connection with the preparation and filing of a Registration Statement on Form S--8 (the “Registration Statement”) with the Securities and Exchange Commission for the purposes of registering under the Securities Act of 1933, as amended, shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), to be issued to eligible participants in accordance with the terms of the EnerJex Resources, Inc. Stock Incentive Plan (the “Plan”).

In connection with the foregoing, we have examined such documents, corporate records and other instruments as we have deemed necessary or appropriate in connection with this opinion. Based upon and subject to the foregoing, we are of the opinion that the Common Stock, when sold and issued in accordance with the Plan, will be validly issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement.

Very truly yours,
