ITEM 5.  OTHER EVENTS

      GENERAL On June 23, 2003, the registrant's subsidiary Rocky Mountain Gas,
Inc. ("RMG"); CCBM, Inc. ("CCBM"), and its parent company Carrizo Oil & Gas,
Inc.; and seven affiliates of Credit Suisse First Boston Private Equity (the
"CSFB Parties") signed and closed agreements for a transaction with Pinnacle Gas
Resources, Inc. ("Pinnacle"), a new-organized Delaware corporation. The
transaction is: (1) the contribution to Pinnacle by RMG and CCBM, of all of
their ownership of a portion of the coalbed methane ("CBM") properties owned by
RMG and CCBM, in exchange for common stock and options to buy common stock in
Pinnacle; and (2) $17.64 million of cash funding to Pinnacle by the CSFB Parties
for common stock of Pinnacle, series A preferred stock of Pinnacle, and warrants
to purchase series A preferred stock of Pinnacle. RMG's ownership in Pinnacle's
common stock presently is 37.5%. RMG's ownership of Pinnacle on a fully-diluted
basis will change if the CSFB Parties fund subsequent capital requests from
Pinnacle and/or exercise their warrants to buy equity in Pinnacle, and/or if RMG
and/or CCBM exercise their options to buy equity in Pinnacle, or other events
occur. See the discussion under Pinnacle Equity Transaction below.

      Immediately following, and in connection with, the transaction, Pinnacle
acquired additional producing and non-producing CBM properties located in the
Powder River Basin of Wyoming from Gastar Exploration, Ltd. ("Gastar," TSE:
"YGA.TO"), referred to below as the "Gastar acquisition."

      The transaction and the follow-on Gastar acquisition provide (1) Pinnacle
the funded opportunity to explore and develop the contributed and acquired
assets, and to acquire and explore, and if warranted develop, additional CBM
properties in Wyoming and Montana; and (2) RMG (through its ownership interest
in Pinnacle) the basis for participation in the continued development of the
contributed assets and assets which may be acquired by Pinnacle in the future.

      RMG now has interests in approximately 320,000 gross acres of CBM
properties: (A) Approximately 189,000 acres in the Castle Rock, Oyster Ridge,
and Baggs properties, which were not contributed to Pinnacle; these properties
are leased directly by RMG (and by its industry partner CCBM, Inc.), and
operated by RMG; and (B) approximately 131,000 acres (including the 38,000 acres
in the Gastar acquisition); these properties are leased directly (and operated)
by Pinnacle.

      RMG is a majority-owned subsidiary of U. S. Energy Corp. ("USE" or the
registrant) and a minority- owned subsidiary of Crested Corp. ("Crested"). CCBM
is a wholly-owned subsidiary of Carrizo Oil & Gas, Inc. ("Carrizo", NASDAQ:
"CRZO"). Carrizo, CCBM and RMG had entered into an agreement in July 2001 for
CCBM to buy a 50% interest in, and fund exploration and development of, RMG's
CBM properties then owned and to be acquired. Prior to and in connection with
the Pinnacle transaction, CCBM paid RMG approximately $1.9 million cash to
complete its purchase of 50% of RMG's contributed CBM properties, thus enabling
CCBM to contribute its interests in the CBM properties to Pinnacle as having
been fully paid for. See "Continuing Operations of RMG, Continuing Agreement
with CCBM, and the AMI Agreement" below.

      The reclassification of investments in CBM properties resulting from the
transaction with Pinnacle will be reflected in the balance sheet to be filed
with the financial statements of the registrant to be included in the Form 10-Q
for the six months ended June 30, 2003.

     Pinnacle is authorized to issue common stock (100 million shares, $0.01 par

with the common stock on regular matters, and (b) as a separate class, to
authorize changes in the series A preferred stock, to authorize issuance of

     (3)     Commitment to fund subsequent capital requests from Pinnacle, not
             more than $11,760,000, if made prior to July 1, 2004, for
             development work on CBM wells, or (if approved by CSFB Parties) a
             property acquisition. The commitment price is $980,000 for each
             10,000 shares of series A stock (coupled with warrants to purchase
             10,000 shares of common stock, exercisable at $100 per share).


                                        3





     The property contributions made by RMG and CCBM to Pinnacle are intended to
constitute transfers under section 351(a) of the Internal Revenue Code of 1986,
as amended. RMG is continuing its business activities in CBM on its own account
separate from the transaction. RMG has significant CBM properties which were not
contributed to Pinnacle. For accounting purposes, the transaction will be
treated as a reclassification of a portion of RMG's investments in CBM. RMG has
continuing representation on Pinnacle's board of directors.

     Sanders Morris Harris Inc. ("SMH") of Houston, Texas acted as financial
advisor to RMG on the transaction. For its services in connection with the
transaction and the Gastar acquisition, SMH will be paid $650,000 by Pinnacle.
As additional compensation for SMH's services, USE has issued to SMH 50,000
restricted shares of common stock of USE and warrants to purchase (until June
30, 2006) another 50,000 restricted shares of common stock (at $5.00 per share).
SMH will not receive any equity or equity rights in Pinnacle in connection with
the transaction or the Gastar acquisition.

     GASTAR ACQUISITION

     With proceeds from the CSFB financing, Pinnacle acquired from Gastar
approximately 50% of Gastar's working interest in existing producing and
non-producing CBM leases which include 95 producing CBM wells currently in the
early stages of dewatering (some of these wells are producing, at a combined
gross rate of approximately 2 MMcfd (million cubic feet per day)) and
approximately 36,529 gross acres prospective for CBM development. The majority
of the leases are either part of or located adjacent to the producing "Bobcat"
property; RMG and CCBM contributed to Pinnacle (in the transaction) all of RMG's
and CCBM's interests in the Bobcat property. The Bobcat property interests
contributed by RMG was the only producing CBM property held by RMG.

     For the approximate 50% working interest in the CBM leases acquired from
Gastar, Pinnacle paid Gastar approximately $6.2 million and Pinnacle agreed to
fund up to $14.5 million of future drilling and development costs on behalf of
Gastar and Pinnacle prior to December 31, 2005, on the acreage contributed by
Gastar to Pinnacle. This drilling and development work will be done under terms
of an earn-in joint venture agreement signed between Pinnacle and Gastar.

     CONTINUING OPERATIONS OF RMG, CONTINUING AGREEMENT WITH CCBM,
     AND THE AMI AGREEMENT

     RMG is continuing its CBM business activities. RMG has retained ownership,
with CCBM, of the Castle Rock, Oyster Ridge, and Baggs projects, totaling about
189,000 gross acres. RMG and CCBM will continue conducting exploration and
development activities on these properties as well as actively pursuing other
potential acquisitions. Presently there are no agreements in place to acquire
other properties.

     With modifications due to the transaction with Pinnacle, RMG and CCBM are
continuing their July 2001 agreement for CBM acquisitions and exploration in
Wyoming and Montana. CCBM paid RMG approximately $1.9 million for CCBM's
outstanding purchase obligations on CCBM's interests in the CBM properties it
contributed to Pinnacle in the transaction with the CSFB Parties. The $1,180,075
balance of CCBM's original purchase obligation is to be paid in monthly
installments of $52,804.82 through November 2004 and a balloon payment on
December 31, 2004.


                                        4




     In connection with the transaction with Pinnacle, RMG and Pinnacle signed a
transition services agreement, for Pinnacle to pay RMG to assist in setting up
operational accounting and management systems for Pinnacle through December
2003. The agreement may be renewed after December 31, 2003 on a quarterly basis.

     Also in connection with the transaction, RMG, CCBM, Carrizo, USE and the
CSFB Parties signed an area of mutual interest ("AMI") agreement: Until June 23,
2008, Pinnacle has the right to acquire from the other parties up to 100% of any
interest in oil and gas leases, or interests therein or mineral interests or
rights to acquire same, which the other parties acquire, at the same price paid
or payable by the other parties, within the Powder River Basin in Montana and
Wyoming (excluding most of Powder River County, Montana). The existing AMI
agreement between CCBM and RMG from July 2001 is superseded by the new AMI
agreement, except for areas outside the new AMI agreement territory.
