VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 17, 2011) -

NOT FOR DISSEMINATION IN THE UNITED STATES OR FOR DISTRIBUTION TO U.S. WIRE SERVICES

Enterprise Energy Resources Ltd. (the "Company") (TSX VENTURE:EER) is pleased to announce the preliminary terms of its previously announced financing.

The Company has entered into an agreement with GMP Securities L.P. to act as lead agent on behalf of a syndicate including Haywood Securities Inc. and Paradigm Capital Inc. (collectively, the "Agents") to undertake a best efforts private placement financing of subscription receipts ("Subscription Receipts") at a price to be agreed to by the Company and the Agents (the "Offering Price") for gross proceeds of up to $25,000,000 (the "Offering"). The Company has also granted the Agents an option (the "Option"), exercisable at any time up to two days prior to the closing of the Offering, to place additional Subscription Receipts at the Offering Price for additional gross proceeds to the Company of up to $5,000,000, for a total offering size of up to $30,000,000.

Each Subscription Receipt will be convertible for no additional consideration into one common share of the Company (a "Common Share") and one-half of one Common Share purchase warrant upon completion of the previously announced acquisition of Cerda Capital Corporation (the "Cerda Acquisition"). Each whole warrant will entitle the holder thereof to purchase one Common Share at a price per Common Share to be agreed to by the Company and the Agents for a period of 180 days following the closing of the Offering. If after 180 days following the closing of the Offering there remain outstanding Warrants, the respective holders will be entitled to purchase one Common Share at a price per Common Share to be agreed to by the Company and the Agents for an additional 180 days.

The closing of the Offering is expected to occur on or about June 22, 2011 and is subject to all necessary regulatory approvals.

The proceeds from the Offering will be used for the purchase consideration payable by the Company in connection with the Cerda Acquisition and the acquisition of Basin Petroleum Limited (See May 10, 2011 News Release) and for ongoing capital expenditures across the Company's core asset base in Montana and North Dakota and for general corporate purposes.

On the closing date of the Offering, the gross proceeds from the Offering will be delivered to and held by a licensed Canadian trust company or other escrow agent pending completion of the Cerda Acquisition.

The proceeds of the Offering will be released to the Company provided that the Cerda Acquisition is completed on or before July 15, 2011 (and provided further that a sufficient amount of the proceeds shall be released to the Company's legal counsel in trust in order to allow the Company to complete the Cerda Acquisition). If the Cerda Acquisition is not completed on or before July 15, 2011, the holders of Subscription Receipts will receive a cash payment equal to the Offering Price multiplied by the number of Subscription Receipts held, together with the earned interest thereon.

Securities issued under the Offering will be subject to a four month hold period beginning upon their issuance.
