Item 10 - Directors and Executive Officers of the Registrant

The information required by Item 10 with respect to directors and certain executive officers is incorporated herein by reference to our Proxy Statement for the Meeting of Shareholders to be held in June 2010, under the captions Proposal 1: Election of Directors, Filing of Reports Under Section 16(a), and Business Experience and Other Directorships of Directors and Nominees.

Information Regarding a Person Nominated, After the Date the Form 10-K for Year Ended December 31, 2009, to Stand for Election as a Director at the June 2010 Annual Meeting.

Stephen V. Conrad (63) Nominated in April 2010 to stand for election as an Independent Director.  Mr. Conrad is a Certified Public Accountant with more than 35 years of experience providing tax services to numerous public and privately-held natural resource companies.  He began his career with Deloitte & Touche (formerly Haskins & Sells) in 1970 and obtained his CPA certificate later that year.  Mr. Conrad became a partner in 1980 and was the national oil and gas industry director from 1982 until 1984.  His duties included providing due diligence and tax structuring advice related to oil and gas mergers and acquisitions.  Mr. Conrad joined Arthur Andersen in 1984 and became the Tax Partner-in-Charge of Andersen’s Den ver Office from 1987 until 1999.  Mr. Conrad was an active participant in Andersen’s firm-wide tax specialty team on oil and gas taxation and co-author of the firm’s Oil and Gas Federal Income Tax Manual.

After leaving Arthur Andersen, Mr. Conrad was a partner with Deloitte & Touche from 2002 to 2005, and from 2006 until 2008, he was a partner with the firm Conrad & Henderson LLP.

He has written several articles on natural resource taxation and has been an adjunct professor at the University of Denver teaching a course on Natural Resource Taxation, and also has been a frequent speaker at the American Petroleum Institute’s annual tax forum.  Mr. Conrad has served as expert witness in several income tax related court proceedings and has significant experience in IRS dispute resolution proceedings, and he has testified before the Treasury Department on numerous proposed oil and gas regulations.

-3-

Mr. Conrad is a CPA and a member of the American Institute of Certified Public Accountants.  He is also a past member of the Colorado Society of Certified Public Accountants, the Petroleum Accountants Society, the Denver Estate Planning Council, the Independent Petroleum Association of America, IPAMS, the Colorado Mining Association, and the AICPA National Resource Tax Committee.  Mr. Conrad received his B.S., Accounting from Montana State University.

During the past five years, Mr. Conrad has been, directly or indirectly, a co-managing member of three privately-held oil and gas drilling partnerships.  These partnerships generally participate in exploration and production programs with reputable oil and gas companies as a non-operating industry partner.

The partnerships, and his interest in them, are as follows:

·   Mr. Conrad is a co-managing member of Conrad Wildes Development GP, L.L.C. (the “Development LLC”).  The Development LLC is the general partner of the Conrad Wildes Development Program, LTD

·   Mr. Conrad is the co-managing member of Conrad Wildes Oil & Gas II, LLC and W. S. Vecta Exploration, LLC.

There is no relationship between U.S. Energy and these two partnerships.

In 2007, U.S. Energy Corp. entered into a Transfer Agreement with Wildes Exploration Mid-Miocene, LP (“WEMM”).  Mr. Conrad owns approximately 50% of WEMM which is entitled to the assignment of a working interest equal to 15% of U.S. Energy’s 20% working interest (a 3% net working interest) after U.S. Energy has recovered 100% of all of its costs plus 6% interest compounded annually for each producing well drilled and completed by PetroQuest within any of the three areas of mutual interest (“AMIs”).  This arrangement was pursuant to the 2007 Exploration and Area of Mutual Interest Agreement with PetroQuest Energy, Inc. for exploration activities in three AMIs in the Gulf Coast region.  WEMM’s working interest will increase to 20% of the Company’s 20% working interest (a 4% net working interest) after the Company has recovered 200% of its costs from each producing well within each of the AMIs.  Mr. Conrad will receive from WEMM one-half of its net revenues out of the working interest (after payout plus interest has been attained by U.S. Energy), after working interest expenses.

Currently, there is only one producing PetroQuest well (the Leghorn well) in the AMIs, although it is possible that additional wells may be drilled by PetroQuest in the AMIs with U.S. Energy’s participation.  This current well has not attained payout for U.S. Energy.  If payout is attained, the U.S. Energy Board of Directors will monitor WEMM’s payments to Mr. Conrad to determine whether the payments will result in his losing status as an “independent director” (should he be elected a director at the 2010 Annual Meeting) of U.S. Energy.

For the period January 1, 2009 through March 12, 2010, Mr. Conrad received no compensation or other payments (in cash or otherwise), directly or indirectly, from U.S. Energy Corp.
