Exhibit 4.1

DESCRIPTION OF SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF

THE SECURITIES EXCHANGE ACT OF 1934

The following summary describes the common stock of U.S. Energy Corp., a Delaware corporation (“U.S. Energy” or the “Company”), which common stock is registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Description of Common Stock

The following description of our common stock is a summary and is qualified in its entirety by reference to our Certificate of Incorporation and our Amended and Restated Bylaws (“Bylaws”), which are incorporated by reference herein, and by applicable law (including Delaware General Corporation Law (“DGCL”)). For purposes of this description, references to “U.S. Energy,” “we,” “our” and “us” refer only to the Company and not to its subsidiaries.

Authorized Capitalization

The Company is authorized to issue up to 245,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share (“Preferred Stock”).

The terms of our preferred stock are not included herein as such preferred stock is not registered under Section 12 of the Exchange Act.

Common Stock

Voting Rights. Each share of our common stock is entitled to one vote on all stockholder matters. Shares of our common stock do not possess any cumulative voting rights.

Except for the election of directors, if a quorum is present, an action on a matter is approved if it receives the affirmative vote of the holders of a majority of the voting power of the shares of capital stock present in person or represented by proxy at the meeting and entitled to vote on the matter, unless otherwise required by applicable law, Delaware law, our Certificate of Incorporation or Bylaws. The election of directors will be determined by a plurality of the votes cast in respect of the shares present in person or represented by proxy at the meeting and entitled to vote, meaning that the nominees with the greatest number of votes cast, even if less than a majority, will be elected. The rights, preferences and privileges of holders of common stock are subject to, and may be impacted by, the rights of the holders of shares of any series of preferred stock that we have designated, or may designate and issue in the future.

Dividend Rights. Each share of our common stock is entitled to equal dividends and distributions per share with respect to the common stock when, as and if declared by our Board of Directors, subject to any preferential or other rights of any outstanding preferred stock.

Liquidation and Dissolution Rights. Upon liquidation, dissolution or winding up, our common stock will be entitled to receive pro rata on a share-for-share basis, the assets available for distribution to the stockholders after payment of liabilities and payment of preferential and other amounts, if any, payable on any outstanding preferred stock.

No Preemptive, Conversion, or Redemption Rights. Holders of our outstanding common stock have no preemptive, conversion, or redemption rights. Shares of our common stock are not assessable. To the extent that additional shares of our common stock may be issued in the future, the relative interests of the then existing stockholders may be diluted.

Fully Paid Status. All outstanding shares of the Company’s common stock are validly issued, fully paid and non-assessable.

Trading Market. Our common stock is listed for trading on the NASDAQ Capital Market under the symbol “USEG”.

Certificate of Incorporation and Bylaws

Certain provisions of the Company’s Certificate of Incorporation, Bylaws and the DGCL, which are summarized below, could have the effect of making it more difficult to change the composition of the Company’s Board of Directors or for any person or entity to acquire control of the Company.

Advance Notice of Stockholder Proposals and Nominations for Directors

Stockholders who seek to nominate directors or to bring business before a stockholder meeting must comply with specified timing requirements and submit to the Company certain information in advance of such meeting, as set forth in the Bylaws. These provisions may impede a stockholder’s ability to bring matters before an annual or special meeting or make nominations for directors.

Authorized but Unissued Shares of Common Stock

Shares of our authorized and unissued common stock are available for future issuances without additional stockholder approval. While the additional shares are not designed to deter or prevent a change of control, under some circumstances we could use the additional shares to create voting impediments or to frustrate persons seeking to affect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our Board of Directors in opposing a hostile takeover bid.

Authorized but Unissued Shares of Preferred Stock.

Under our Certificate of Incorporation, our Board of Directors has the authority, without further action by our stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the voting powers, designations, preferences and the relative participating, optional or other special rights and qualifications, limitations and restrictions of each series, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series. The existence of authorized but unissued preferred stock could reduce our attractiveness as a target for an unsolicited takeover bid since we could, for example, issue shares of preferred stock to parties who might oppose such a takeover bid or shares that contain terms the potential acquirer may find unattractive. This may have the effect of delaying or preventing a change of control, may discourage bids for the common stock at a premium over the market price of the common stock, and may adversely affect the market price of, and the voting and other rights of the holders of, our common stock.

Classified Board of Directors

In accordance with the terms of our Certificate of Incorporation, our Board of Directors is divided into three classes, Class One, Class Two and Class Three, with members of each class serving staggered three-year terms. Under our Certificate of Incorporation, our Board of Directors consists of such number of directors as may be determined from time to time by resolution of the Board of Directors, but in no event may the number of directors be less than one or more than fifteen. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Our Certificate of Incorporation provides that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by the affirmative vote of a majority of our directors then in office, even if less than a quorum, or by a sole remaining director. Any director elected to fill a vacancy will hold office until such director’s successor shall have been duly elected and qualified or until such director’s earlier death, resignation or removal. Our classified Board of Directors could have the effect of delaying or discouraging an acquisition of us or a change in our management.

Removal of Directors

As a result of our classified Board of Directors, our Bylaws provide that directors may be removed only for cause and upon the affirmative vote of holders of at least a majority of the outstanding shares of common stock then entitled to vote at an election of directors.

Special Meeting of Stockholders

Special meetings of stockholders may only be called by a majority vote of our board of directors.

Action by Written Consent

Any action required or permitted to be taken by our common stockholders may be effected by written consent of the stockholders having not less than the minimum percentage of the vote required by DGCL for the proposed corporate action.

Vacancies on the Board of Directors

Our Certificate of Incorporation and Bylaws provide that, subject to the rights of the holders of any outstanding series of preferred stock and unless otherwise required by law or resolution of our board of directors, vacancies on the board of directors arising through death, resignation, retirement, disqualification or removal, an increase in the number of directors or otherwise may be filled by a majority of the directors then in office, though less than a quorum.

Amendment to Bylaws by Stockholders

Subject to certain limitations preventing amendments which decrease or diminish indemnification rights provided for in our Bylaws, our Bylaws provide that any amendment to such Bylaws undertaken solely by our stockholders requires the affirmative vote of at least a majority in voting power of the outstanding shares of capital stock of the Company.

Forum Selection Clause

Our Certificate of Incorporation provides that unless the Company consents in writing to the selection of an alternative forum (an “Alternative Forum Consent”), the Court of Chancery of the State of Delaware is the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim for breach of a fiduciary duty owed by any current or former director, officer, employee or stockholder of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of DGCL, the Certificate of Incorporation or the Bylaws of the Company, each as amended, or (iv) any action asserting a claim governed by the internal affairs doctrine; provided, however, that, in the event that the Court of Chancery of the State of Delaware lacks subject matter jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall be another state or federal court located within the State of Delaware, in each such case, unless the Court of Chancery (or such other state or federal court located within the State of Delaware, as applicable) has dismissed a prior action by the same plaintiff asserting the same claims because such court lacked personal jurisdiction over an indispensable party named as a defendant therein.

The following provisions would not however apply to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended (the “Securities Act”), the Exchange Act, or any other claim for which the U.S. federal courts have exclusive jurisdiction. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder and Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act, and an investor cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Notwithstanding the above, to prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our Certificate of Incorporation provides that unless the Company gives an Alternative Forum Consent, the U.S. federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. However, there is uncertainty as to whether a court would enforce such a provision. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our Certificate of Incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive-forum provision to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

Anti-Takeover Effects Under Section 203 of Delaware General Corporation Law

Section 203 of Delaware General Corporation Law prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

In general, Section 203 defines “business combination” to include the following:

In general, Section 203 defines an “interested stockholder” as an entity or a person who, together with the person’s affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15 percent or more of the outstanding voting stock of the corporation.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us will not be limited by Section 203 of Delaware law.

* * * * *

The provisions of Delaware law and the provisions of our Certificate of Incorporation and Bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they might also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions might also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.
