Enterprise Enters Into Letter Agreements to Acquire Interests in Oil and Gas Leases in the Williston Basin, Montana

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 that it has entered into two letter agreements for the acquisition of
interests in oil and gas leases in the Williston Basin, Montana.


The increasing oil production from the Williston Basin in North Dakota and
Montana is resulting in record levels of drilling activity. The oil and gas
leases to be acquired by the Company are in an area that is receiving increased
attention as the industry focus that began in North Dakota moves west into
Montana. 


Cerda Williston acreage (approximately 30,840 net acres)

Under a letter agreement (the "Cerda Agreement") the Company proposes to acquire
from EVO Energy Ltd. ("EVO") all of the shares of Cerda Capital Corporation
("Cerda"). Cerda, through a subsidiary, is party to a purchase and sale
agreement under which it proposes to acquire from an undisclosed party ("Cerda
Vendor") oil and gas leases over approximately 30,840 net acres in the Williston
Basin, Montana. 


Williston Basin leasing program

Under a second letter agreement (the "Basin Agreement") the Company will acquire
from Unconventional Energy Partners L.P. ("UEC") all of the shares of Basin
Petroleum Ltd. ("Basin"). Basin, through a subsidiary, is party to a program
agreement with Cisk Ventures Ltd. ("Cisk") under which Cisk is assisting Basin
in currently leasing lands in the Williston Basin, Montana.


The transactions contemplated under the Cerda Agreement and the Basin Agreement
are independent of each other and either may close without the other closing.
Together the transactions will be a "Fundamental Acquisition" in accordance with
the policies of the TSX Venture Exchange (the "TSXV"). Each transaction is
subject to approval by the TSX Venture Exchange, the completion of the financing
and other customary conditions.


Cerda Agreement Terms

Under the Cerda Agreement, the Company will acquire all of the shares of Cerda
(the "Cerda Acquisition") for a purchase price to be paid at closing consisting
of approximately USD$1,000,000 (subject to adjustment) and the issuance of
5,000,000 common shares of the Company. The shares will be issued to the
shareholders of EVO (Cerda's parent) on a proportionate basis. In addition, the
Company will be required to pay a cash bonus payment of the greater of
CAD$5,000,000 and 3.0% of the value of the lands acquired from the Cerda Vendor
(the "Cerda Lands"). The bonus is payable on earlier of the third anniversary of
closing or the occurrence of certain specified events. The bonus may be paid by
the Company returning to EVO all of its interest in the Cerda Lands. The Company
has paid a USD$500,000 deposit which is refundable only in certain limited
circumstances. The deposit will be applied at closing to the purchase price.


Cerda is a BVI company which indirectly owns all of the shares of Evolution Oil
Group, LLC ("Evolution Oil"), a limited liability Delaware company. Evolution
Oil is party to a purchase and sale agreement (the "Cerda PSA") with the Cerda
Vendor under which Evolution Oil will acquire from the Cerda Vendor the Cerda
Lands, which consist of approximately 30,840 net acres in the Williston Basin,
Montana. The consideration payable by Evolution Oil to the Cerda Vendor is
approximately USD$7,760,000 (subject to adjustment). In accordance to the
Cerda's PSA, the Cerda Vendor shall deliver to Evolution Oil an 80% net revenue
interest and 100% working interest on the Cerda Lands. The Cerda Vendor will
retain an option to acquire an undivided 10% working interest in the Cerda
Lands, where the Cerda Vendor may have the option to elect to receive the 10%
carried working interest in any of the first four wells drilled within a
specified period and the option to elect to participate for a 10% working
interest in subsequent wells. Cerda and its subsidiaries have no material assets
or operations other than the rights under the Cerda Agreements and certain cash
deposits paid to the Cerda Vendor. Subsequent to the closing of the Cerda
Acquisition, the Company will be responsible for funding the purchase price
payable to the Cerda Vendor.


Closing of the Cerda Acquisition will be subject to a number of conditions,
including but not limited to: (a) entering into a formal share purchase
agreement to replace the Cerda Agreement; (b) completion of due diligence; (c)
the approval of the TSXV; and (d) the completion of a financing to raise in
aggregate not less than CAD$20,000,000 or such lesser amount as acceptable to
the Company.


Basin Agreement Terms

Under the Basin Agreement, the Company will acquire all of the shares of Basin
(the "Basin Acquisition") for a purchase price to be paid at closing consisting
of: (a) the amount of equity invested and loans made by UEC into Basin as at the
time of closing plus 12.5% of such amounts, and (b) the issuance of up to
9,000,000 common shares of the Company. In addition, the Company will be
required to pay a cash bonus payment of the greater of CAD$5,000,000 and 3.0% of
the value of the lands acquired under the program agreement with Cisk (the "Cisk
Lands"). The bonus is payable on earlier of the third anniversary of closing or
the occurrence of certain specified events. The bonus payment may increase to
the greater of USD$7,000,000 and 4% of the value of the Cisk Lands if certain
events occur prior to closing. The bonus may be paid by the Company returning to
UEC all of its interest in the Cisk Lands. The amount payable under (a) above
will be not less than USD$3,200,000 but will increase as UEC provides further
funding to Basin to enable Basin to continue to lease additional acreage. The
Company has paid a USD$500,000 deposit which is refundable only in certain
limited circumstances. The deposit will be applied at closing to the purchase
price.


Basin is a BVI company which indirectly owns all of the shares of Unconventional
Energy Partners, LLC ("UEP"), a limited liability Montana company. UEP is party
to a program agreement (the "Cisk Agreement") with Cisk under which Cisk is
assisting UEP in leasing acreage in the Williston Basin (the "Basin Lands"). The
leasing program is being undertaken in several stages and is already underway.
If all of the stages are completed UEP estimates the total leased acreage will
cost approximately USD$12,000,000. Under the Cisk Agreement, the Basin Lands
will have a minimum net revenue interest to UEP of 80%. Basin and its
subsidiaries have no material assets or operations other than oil and gas leases
acquired or to be acquired under the Cisk Agreement and the funding and
activities necessary to complete such acquisitions. To the extent UEC funds
Basin so that UEP may acquire oil and gas leases prior to closing the Basin
Acquisition, the purchase price for the shares of Basin will increase. Similarly
if Basin requires further funding to continue leasing after the closing of the
Basin Acquisition, the Company will be responsible for providing such funding.
Under the Cisk Agreement, the Company will issue to Cisk 750,000 common shares
of the Company upon completion of each of the three stages of the leasing
program, for a total of up to 2,250,000 shares. In addition Cisk may elect to
have up to USD$1,800,000 of amounts owing to it to be paid by the issuance of
common shares of the Company at a price equal to the greater of the market value
at the time of issuance and USD$1.00 per share.


Closing of the Basin Acquisition will be subject to a number of conditions,
including but not limited to: (a) entering into a formal share purchase
agreement to replace the Basin Agreement; (b) completion of due diligence; (c)
the approval of the TSXV; and (d) the completion of a financing to raise in
aggregate not less than CAD$20,000,000 or such lesser amount as acceptable to
the Company.


Financing

As a condition to each of the Cerda Transaction and the Basin Transaction, the
Company must complete a financing (the "Financing"). The proceeds from the
Financing will be used to fund the Cerda Transaction and the Basin Transaction,
and the commitments assumed by the Company upon closing such transactions under
the Cisk Agreement and the Cerda PSA. The Company proposes to raise up to
CAD$30,000,000 under the Financing. The terms and conditions of the Financing
have not been determined and there is no assurance that Financing will be
completed.
