AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of January 23, 2007 is by and between U.S. Energy Corp., a Wyoming corporation (“Parent”), and Crested Corp., a Colorado corporation (the “Company”).

WHEREAS, the parties desire that the Company be merged with and into Parent with Parent as the surviving company, all as set forth in Article 1 of this Agreement;

WHEREAS, the boards of directors of Parent and the Company established special committees in order to evaluate the proposed Merger (as defined below), and each special committee evaluated the Merger and recommended approval of the Merger to its board of directors;

WHEREAS, the boards of directors of Parent and the Company have approved this Agreement and deem it advisable and in the best interests of their respective stockholders to consummate the transactions contemplated hereby on the terms and conditions set forth herein;

WHEREAS, in consideration of Parent entering into this Agreement and incurring certain related fees and expenses, Parent, the officers and directors of Parent who own Company Common Stock and the Company are executing a voting agreement, of even date herewith (the “Voting Agreement”), relating to the Company Common Stock (as defined below) beneficially owned by Parent;

WHEREAS, it is intended that, for United States federal income tax purposes, the Merger (as defined below) shall qualify as a reorganization within the meaning of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated thereunder and this Agreement constitutes a “plan of reorganization” within the meaning of Section 1.368(c) of the Treasury Regulations.

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants contained in this Agreement and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Parent and the Company, intending to be legally bound, hereby agree as follows:

ARTICLE 1

THE MERGER

1.1 The Merger.

(a) On the terms and subject to the conditions set forth in this Agreement, and in accordance with the Colorado Business Corporation Act (“CBCA”) and the Wyoming Business Corporation Act (“WBCA”), the Company shall be merged with and into Parent at the Effective Date (the “Merger”). At the Effective Date, the separate corporate existence of the Company shall cease and Parent shall continue as the surviving corporation of the Merger (the “Surviving Company”).

(b) It is intended that the Merger shall constitute a reorganization under the Code.

1.2 Closing. Unless this Agreement is earlier terminated, the closing (the “Closing”) of the Merger shall take place at the offices of Parent, ▇▇▇ ▇▇▇▇▇ ▇^▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, at 10:00 am on the first business day following the satisfaction or waiver (to the extent permitted by applicable Law (as defined in Section 2.13)) of the conditions set forth in Article 6, or at such other place, time and date as shall be agreed in writing between Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

1.3 Effective Date. Prior to the Closing, Parent shall prepare, and on the Closing Date or as soon as practicable thereafter, Parent shall file (a) a statement of merger (the “Statement of Merger”) executed in accordance with the relevant provisions of the Colorado Corporations and Associations Act (the “CCAA”) with the Secretary of State of the State of Colorado, and (b) articles of merger (“Articles of Merger”) executed in accordance with the relevant provisions of the WBCA with the Secretary of State of the State of Wyoming. The Merger shall become effective at such time as both the Statement of Merger and the Articles of Merger have been duly filed with the Secretaries of State of the States of Colorado and Wyoming, or at such subsequent time as Parent and the Company shall agree and specify in the Statement of Merger and the Articles of Merger (the date the Merger becomes effective being the “Effective Date”).

1.4 Effects of the Merger. The Merger shall have the effects set forth in section 7-90-204(1)(a) of the CCAA and section 17-16-1106(a) of the WBCA. The articles of incorporation and bylaws of Parent immediately prior to the Effective Date shall be the articles of incorporation and bylaws of the Surviving Company. The directors and officers of Parent immediately prior to the Effective Date shall continue in service until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified, as the case may be. When Parent deems it appropriate, the joint venture between Parent and the Company (“USECB Joint Venture”) shall be terminated and wound up.

1.5 Effect on Capital Stock. At the Effective Date, by virtue of the Merger and without any action on the part of the holder of any shares of common stock, par value $0.001, of the Company (“Company Common Stock”), the following shall occur:

(a) Cancellation Of Treasury Stock, Parent-Owned Stock and Certain Parent Common Stock. Each share of Company Common Stock that is owned by the Company or Parent shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor. Any common stock of Parent (“Parent Common Stock”) owned by the Company shall no longer be outstanding and shall automatically be canceled and shall cease to exist.

(b) Conversion Of Company Common Stock; Merger Consideration. Subject to Sections 1.5(a), 1.6 and 1.7(e), every two issued and outstanding shares of Company Common Stock not held by Parent (including shares of Company Common Stock issued on exercise of the Company Stock Options (as those terms are defined in Section 1.6 below)) shall be converted into the right to receive one validly issued, fully paid and non-assessable share of Parent Common Stock (the “Merger Consideration”), resulting in an exchange ratio of 2:1 (the “Exchange Ratio”). The Merger Consideration on the Effective Date is subject to (i) reduction by operation of sections ▇-▇▇▇-▇▇▇ to ▇-▇▇▇-▇▇▇ of the CBCA (the “Dissenters’ Rights Statute”); and (ii) increase by such additional shares as may be needed to pay for fractional shares of Company Common Stock under Section 1.7(e) (such additional share number not being determinable until the Effective Date).

(c) Effect Of Conversion. From and after the Effective Date, all of the shares of Company Common Stock converted into the Merger Consideration pursuant to this Section 1.5 shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of such shares evidenced by a certificate (each a “Stock Certificate”), representing any such shares of Company Common Stock (and each holder of shares of Company Common Stock issued upon exercise of a Company Stock Option, but not evidenced by a stock certificate) shall thereafter cease to have any rights with respect thereto, except the right to receive (i) the Total Merger Consideration, (ii) any dividends and other distributions in accordance with Sections 1.7(d) and 1.7(f); (iii) any cash to be paid to an Electing Cash Out Holder (as defined below) under Section 1.5(c)(1); and (iv) rights to payment under the Dissenters’ Rights Statute.

(d) Payments to Electing Cash Out Holders. In the form to be included in the proxy as part of the Prospectus/Proxy Statement, Parent shall provide an option to all holders of 500 or fewer shares of Company Common Stock to elect to receive cash in lieu of shares of Parent Common Stock (the “Electing Cash Out Holders”). Upon receiving the elections from Electing Cash Out Holders, Parent may elect either to (i) pay each Electing Cash Out Holder, in cash, the amount of cash equal to the number of shares of Parent Common Stock to which the Electing Cash Out Holder otherwise would be entitled, multiplied by the closing price of one share of Parent Common Stock on the Nasdaq Capital Market on the Effective Date, or (ii) reject the election of each Electing Cash Out Holder, and issue shares of Parent Common Stock in accordance with this Article.

(e) Changes To Stock. If at any time during the period between the date of this Agreement and the Effective Date, any change in the outstanding shares of capital stock of Parent or the Company shall occur by reason of any reclassification, recapitalization, stock split or combination, split-up, exchange or readjustment of shares, rights issued in respect of Parent Common Stock or any stock dividend thereon with a record date during such period, the Merger Consideration and any other similarly dependent items, as the case may be, shall be appropriately adjusted to provide the holders of shares of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.

1.6 Stock Options, and Equity and Other Compensation Plans and Benefits. The board of directors of the Company (the “Company Board”), or the appropriate committee thereof, shall take such action as is within its power so that (i) at the Effective Date, each outstanding option to purchase shares of Company Common Stock (a “Company Stock Option”) granted under the Company’s Incentive Stock Option Plan (the “Company Stock Plan”), whether or not vested, is exercisable by its holder on a “cashless exercise” basis, and each exercising holder shall, on the Effective Date, be entitled to receive her or his portion of the Merger Consideration, and (ii) after the Effective Date, any unexercised Company Stock Option shall cease to represent a right to acquire shares of Company Common Stock and shall be administered in accordance with the Company Stock Plan. All other compensation arrangements or plans or benefit plans (including without limitation salary, and insurance and retirement benefits) with or for the benefit of persons who may be deemed to be employees of the Company, and who also are employees of Parent, shall be terminated, but all such arrangements and plans for such persons as employees of Parent which are in place at the Effective Date shall not be affected as a result of the Merger.

1.7 Exchange Of Certificates.

(a) Exchange Agent. Computershare Trust Company (which also is the stock transfer agent for Parent and the Company) shall serve as the exchange agent for the Parent Common Stock (the “Exchange Agent”) for the purpose of exchanging Stock Certificates representing shares of Company Common Stock and non-certificated shares represented by book entry (“Book-Entry Shares”) for the Total Merger Consideration. Upon request by a holder of Company Common Stock, a stock certificate shall be issued to such a holder in lieu of Book-Entry Shares. Promptly after the Effective Date (but in any event within five business days thereafter), Parent will send, or will cause the Exchange Agent to send, to each holder of record of shares of Company Common Stock as of the Effective Date (exclusive of Electing Cash Out Holders) a letter of transmittal for use in such exchange (which shall specify that delivery shall be effected, and risk of loss and title to the Stock Certificates theretofore representing shares of Company Common Stock shall pass, only upon proper delivery of such Stock Certificates to the Exchange Agent or by appropriate guarantee of delivery in the form customarily used in transactions of this nature from a member of a national securities exchange, a member of the National Association of Securities Dealers, Inc., or a commercial bank or trust company in the United States) in such form as the Company and Parent may reasonably agree, for use in effecting delivery of shares of Company Common Stock to the Exchange Agent. Exchange of any Book-Entry Shares of the Company which are outstanding shall be effected in accordance with Parent’s customary procedures with respect to securities represented by book entry.

(a)(1) No Requirement for Issuance of Stock Certificates for Company Common Stock Issued on Exercise of Company Stock Options. If permitted by the Company’s articles of incorporation and bylaws, and by the operating procedures of the Exchange Agent, the Company shall not be required to issue stock certificates for shares of Company Common Stock issued upon exercise of Company Stock Options, and shares of Parent Common Stock shall be issued against such documentation as the Exchange Agent may request.

(b) Exchange Procedure. Each holder of shares of Company Common Stock that have been converted into a right to receive the Total Merger Consideration, upon surrender to the Exchange Agent of a Stock Certificate (or other documentation if a stock certificate is not issued under Section 1.7(a)(1)), together with a properly completed letter of transmittal, will be entitled to receive (i) one or more shares of Parent Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant to Section 1.5(b), plus one additional share if the holder otherwise would have the right to receive a fractional share under Section 1.7(e) and dividends and other distributions pursuant to Section 1.7(d) and 1.7(f). No interest shall be paid or accrued on any of the Total Merger Consideration, or on any unpaid dividends and distributions payable to holders of Stock Certificates or holders of Company shares without certificates. Until so surrendered, each such Stock Certificate shall, after the Effective Date, represent for all purposes only the right to receive such Merger Consideration and any dividends and other distributions in accordance with Sections 1.7(d) and 1.7(f), and an additional one share as applicable in lieu of any fractional share of Parent Common Stock.

(c) Certificate Holder. If any portion of the Merger Consideration is to be registered in the name of a person other than the person in whose name the applicable surrendered Stock Certificate is registered, it shall be a condition to the registration thereof that the surrendered Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other similar taxes required as a result of such registration in the name of a person other than the registered holder of such Stock Certificate or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(d) Dividends And Distributions. No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger shall be paid to the holder of any unsurrendered Stock Certificates or Book-Entry Shares until such Stock Certificates or Book-Entry Shares are properly surrendered. Following such surrender, there shall be paid, without interest, to the record holder of the shares of Parent Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of such shares of Parent Common Stock with a record date after the Effective Date and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of Parent Common Stock with a record date after the Effective Date but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of shares of Parent Common Stock, all shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Date.

(e) Fractional Shares. No fractional shares of Parent Common Stock shall be issued in the Merger, but in lieu thereof each holder of Company Common Stock otherwise entitled to a fractional share of Parent Common Stock will be entitled to receive one additional share of Parent Common Stock. No cash payment shall be made for fractional shares of Parent Common Stock.

(f) No Further Ownership Rights In Company Common Stock. The Total Merger Consideration paid in accordance with the terms of this Article I upon conversion of any shares of Company Common Stock shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock, subject, however, to the Surviving Company’s obligation to pay any dividends or make any other distributions with a record date prior to the Effective Date that may have been declared or made by the Company on such shares of Company Common Stock in accordance with the terms of this Agreement or prior to the date of this Agreement and which remain unpaid at the Effective Date. After the Effective Date there shall be no further registration of transfers on the equity transfer books of the Surviving Company of shares of Company Common Stock that were outstanding immediately prior to the Effective Date. If, after the Effective Date, any Stock Certificates formerly representing shares of Company Common Stock are presented to the Surviving Company or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article I.

(g) No Liability. None of Parent, the Company or the Exchange Agent shall be liable to any person in respect of any Parent Common Stock delivered to a public official to the extent required by any applicable abandoned property, escheat or similar Law. If any Stock Certificate has not been surrendered immediately prior to such date on which the Merger Consideration in respect of such Stock Certificate would otherwise irrevocably escheat to or become the property of any governmental entity, any such shares, cash, dividends or distributions in respect of such Stock Certificate shall, to the extent permitted by applicable Law, become the property of the Surviving Company, free and clear of all claims or interest of any person previously entitled thereto, except as otherwise provided by Law.

(h) Withholding Rights. Parent and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Company Common Stock pursuant to this Agreement such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or under any other provision of applicable federal, state, local or foreign tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent or the Exchange Agent, as applicable, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holders of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent or the Exchange Agent.

(i) Lost Certificates. If any Stock Certificate shall have been lost, stolen, defaced or destroyed, upon the making of an affidavit of that fact by the person claiming such Stock Certificate to be lost, stolen, defaced or destroyed and, if reasonably required by Exchange Agent, the posting by such person of a bond in such reasonable amount as Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such Stock Certificate, the Exchange Agent shall pay in respect of such lost, stolen, defaced or destroyed Stock Certificate the Merger Consideration with respect to each share of Company Common Stock formerly represented by such Stock Certificate.

1.8 Taking of Necessary Action; Further Action. Parent and the Company shall use all reasonable efforts to take all such actions as may be necessary or appropriate in order to effectuate the Merger as promptly as commercially practicable. If, at any time after the Effective Date, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Parent with full right, title and possession to all assets, property, rights, privileges, powers and franchises of either the Company or the USECB Joint Venture, the officers of Parent are fully authorized in the name of each constituent entity or otherwise to take, and shall take, all such lawful and necessary action.

ARTICLE 2

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as publicly disclosed by the Company in the Company SEC Reports (as defined in Section 2.4(a)) filed with the Securities and Exchange Commission (“SEC”) prior to the date of this Agreement and except as set forth on the disclosure letter (each section of which qualifies the correspondingly numbered representation and warranty or covenant to the extent specified therein, provided that any disclosure set forth with respect to any particular section shall be deemed to be disclosed in reference to all other applicable sections of this Agreement and the disclosure letter) previously delivered by the Company to Parent (the “Company Disclosure Letter”), the Company hereby represents and warrants to Parent as follows. “To the knowledge of the Company” and similar phrases mean the actual knowledge of the Chief Executive Officer and Chief Financial Officer of the Company.

2.1 Organization.

(a) The Company owns a 50% interest in the USECC Joint Venture with Parent, through which they conduct all their business. Additionally, the Company owns a 1.2% ownership in ▇▇▇▇▇▇ Gold Mining, Inc. (“SGMI”). The Company also participates in mineral property ownership with Parent and has a cash flow sharing arrangement with the Parent on uranium properties in southern Utah, which are owned by Plateau Resources Limited, a 100% owned subsidiary of Parent. The Company therefore has no consolidated subsidiaries. Any reference to “Company Subsidiaries” refers to USECC, SGMI or Plateau. Each of the Company and the Company Subsidiaries is duly organized, validly existing and in good standing under the Laws of the jurisdiction of its organization and has the requisite corporate or limited partnership power and authority and any necessary governmental approvals to own, lease and operate its property and to carry on its business as now being conducted. The Company and each of the

Company Subsidiaries is duly qualified and/or licensed, as may be required, and in good standing in each of the jurisdictions in which the nature of the business conducted by it or the character of the property owned, leased or used by it makes such qualification and/or licensing necessary, except in such jurisdictions where the failure to be so qualified and/or licensed would not, individually or in the aggregate, have a Company Material Adverse Effect. A “Company Material Adverse Effect” means any change, effect, fact, event, condition or development that would have or be reasonably likely to have a material adverse effect on (i) the condition (financial or otherwise), business, operations or assets of the Company and the Company Subsidiaries considered as a single enterprise or (ii) the ability of the Company to consummate the transactions contemplated by this Agreement. Notwithstanding anything to the contrary herein, any change, effect, fact, event or condition (x) which adversely affects the minerals industry generally or (y) which arises out of general economic conditions shall not be considered in determining whether a Company Material Adverse Effect has occurred. The copies of the articles of incorporation, and amendments, and bylaws of the Company which are filed as exhibits to the Company’s SEC Reports are complete and correct copies of such documents as in effect on the date of this Agreement.

(b) Section 2.1(b) of the Company Disclosure Letter lists all of the Company Subsidiaries and their respective jurisdictions of incorporation. All the outstanding shares of capital stock of, or other equity interests in, each Company Subsidiary have been validly issued and are fully paid and nonassessable and are owned directly or indirectly by the Company, free and clear of all pledges, claims, liens, charges, encumbrances and security interests of any kind or nature whatsoever (“Liens”) and free of any other restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other ownership interests). Other than joint ventures, operating agreements and similar arrangements typical in the Company’s industry entered into in the ordinary course of business, neither the Company nor any of the Company Subsidiaries directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any other person that is or would reasonably be expected to be material to the Company and the Company Subsidiaries considered as a single entity, other than the shares of Parent Common Stock owned by the Company or any Company Subsidiary. The term “person” as used in this Agreement will be interpreted broadly to include any corporation, company, group, partnership or other entity or individual.

2.2 Capital Stock of the Company.

(a) As of the date of this Agreement, the authorized capital stock of the Company consists of 100,000,000 shares of Company Common Stock, of which 17,182,704 are issued and outstanding, and 100,000 shares of Preferred Stock, of which none are issued and outstanding. No shares of Company Common Stock are held in the treasury of the Company. Such issued shares of Company Common Stock have been duly authorized, validly issued, are fully paid and nonassessable, and are free of preemptive rights. The Company has not declared or paid any dividend, or declared or made any distribution on, or authorized the creation or issuance of, or issued, or authorized or effected any split-up or any other recapitalization of, any of its capital stock, or directly or indirectly redeemed, purchased or otherwise acquired any of its outstanding capital stock. The Company has not agreed to take any such action, and there are no outstanding contractual obligations of the Company to repurchase, redeem or otherwise acquire any outstanding shares of capital stock of the Company.

(b) Section 2.2(b) of the Company Disclosure Letter lists all outstanding options (including the holders of Company Stock Options), warrants or other rights to subscribe for, purchase or acquire from the Company any capital stock of the Company or securities convertible into or exchangeable for capital stock of the Company. There are no stock appreciation rights (“SARs”) attached to the options, warrants or rights.

(c) Except for obligations under the USECB Joint Venture, and except as otherwise described in this Section 2.2 or as described in Section 2.2(b) of the Company Disclosure Letter, the Company is not subject to or bound by any outstanding option, warrant, call, subscription or other right (including any preemptive or similar right), agreement, arrangement or commitment which (i) obligates the Company to issue, sell or transfer, or repurchase, redeem or otherwise acquire, any shares of the capital stock or other equity interests of the Company, (ii) obligates the Company to provide funds to make any investment (in the form of a loan, capital contribution or otherwise) or any other entity, (iii) restricts the transfer of any shares of capital stock of the Company or (iv) relates to the holding, voting or disposition of any shares of capital stock of the Company. No bonds, debentures, notes or other indebtedness of the Company having the right to vote (or convertible into, or exchangeable for, securities having the right to vote) on any matters on which the stockholders of the Company may vote are issued or outstanding.

2.3 Authority Relative to this Agreement.

(a) The Company has the requisite corporate power to enter into this Agreement and to carry out its obligations hereunder. The execution and delivery of this Agreement by the Company, the performance by the Company of its obligations hereunder and the consummation by the Company of the transactions contemplated herein have been duly authorized by the Company Board.

REPRESENTATIONS AND WARRANTIES OF PARENT

3.1 Organization.

(a) Each of Parent and Parent Subsidiaries (as defined below) is duly organized, validly existing and in good standing under its jurisdiction of incorporation or formation. Each of Parent and Parent Subsidiaries has the requisite corporate power and authority and any necessary governmental approvals to own, lease and operate its property and to carry on its business as now being conducted. Each of Parent and Parent Subsidiaries is duly qualified and/or licensed, as may be required, and in good standing in each of the jurisdictions in which the nature of the business conducted by it or the character of the property owned, leased or used by it makes such qualification and/or licensing necessary, except in such jurisdictions where the failure to be so qualified and/or licensed would not, individually or in the aggregate, have a Parent Material Adverse Effect. A “Parent Material Adverse Effect” means any change, effect, fact, event, condition or development that would have or be reasonably likely to have a material adverse effect on (i) the condition (financial or otherwise), business, operations or assets of Parent and each corporation, partnership, joint venture or other legal entity of which Parent owns, directly or indirectly, 50% or more of the stock or other equity interests the holder of which is generally entitled to vote for the election of the board of directors or other governing body of such corporation or other legal entity (the “Parent Subsidiaries,” but for purposes of this Article 3, the Company is not deemed to be a Parent Subsidiary) considered as a single enterprise or (ii) the ability of Parent to consummate the transactions contemplated by this Agreement. Notwithstanding anything to the contrary herein, any

change, effect, fact, event or condition which adversely affects the minerals industry generally or which arises out of general economic conditions shall not be considered in determining whether a Parent Material Adverse Effect has occurred. The copies of the articles of incorporation and amendments and the bylaws of Parent which are filed as exhibits to Parent’s SEC Reports are complete and correct copies of such documents as in effect on the date of this Agreement.

(b) All the outstanding shares of capital stock of, or other equity interests in, each Parent Subsidiary have been validly issued and are fully paid and nonassessable and are owned directly or indirectly by Parent, free of all Liens and free of any other restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other ownership interests). Neither Parent nor any of the Parent Subsidiaries directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any other person that is or would reasonably be expected to be material to Parent and the Parent Subsidiaries considered as a single entity.

3.2 Capital Stock.

All issued shares of Parent Common Stock (excluding for this purpose the treasury shares) have been duly authorized, validly issued, are fully paid and nonassessable, and are free of preemptive rights. Parent has not declared or paid any dividend, or declared or made any distribution on, or authorized the creation or issuance of, or issued, or authorized or effected any split-up or any other recapitalization of, any of its capital stock, or directly or indirectly redeemed, purchased or otherwise acquired any of its outstanding capital stock. Parent has not agreed to take any such action, and there are no outstanding contractual obligations of Parent to repurchase, redeem or otherwise acquire any outstanding shares of capital stock of Parent.

(b) Section 3.2(b) of the Parent Disclosure Letter lists all outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Parent any capital stock of the Parent or securities convertible into or exchangeable for capital stock of the Parent. There are no SARs attached to the options, warrants or rights.

(c) Except for their obligations under the USECB Joint Venture, and except as otherwise described in this Section 3.2 or as described in Section 3.2(b) of the Parent Disclosure Letter, the Parent has no, nor is it subject to or bound by any outstanding option, warrant, call, subscription or other right (including any preemptive or similar right), agreement, arrangement or commitment which (i) obligates the Parent to issue, sell or transfer, or repurchase, redeem or otherwise acquire, any shares of the capital stock or other equity interests of the Parent, (ii) obligates the Parent to provide funds to make any investment (in the form of a loan, capital contribution or otherwise) or any other entity, (iii) restricts the transfer of any shares of capital stock of the Parent, or (iv) relates to the holding, voting or disposition of any shares of capital stock of the Parent.

In case at any time after the Effective Date any further action is necessary or desirable to carry out the purposes of this Agreement, that action shall be taken.

after consultation with its financial advisors and outside counsel, that failing to take such action would reasonably be expected to constitute a breach of the fiduciary duties of the board of directors and that the relevant Takeover Proposal is a Superior Proposal (as defined below) and (y) prior to the Shareholders’ Meeting, if the Company receives an unsolicited bona fide written Takeover Proposal from a third party that the board of directors of the Company determines in good faith (after receiving the advice of a financial adviser of nationally or regionally recognized reputation) is reasonably likely to be a Superior Proposal, the Company and its representatives may conduct such discussions or provide such information as the board of directors of the Company shall determine, but only if, prior to such provision of information or conduct of such discussions, (A) such third party shall have entered into a confidentiality agreement, and (B) the board of directors of the Company determines in its good faith judgment, after consultation with outside counsel, that it is required to do so in order to comply with its fiduciary duties.

(c) For purposes of this Agreement, “Takeover Proposal” means any proposal or offer (whether or not in writing and whether or not delivered to the stockholders of the Company generally) for a merger or other business combination, reorganization, share exchange, recapitalization, liquidation, dissolution or similar transaction involving the Company or to acquire in any manner (including by tender or exchange offer), directly or indirectly, a 25% or more equity interest in, any voting securities of, or assets (including equity interests in other entities) of the Company having an aggregate value equal to 10% or more of the Company’s consolidated net asset value, other than the transactions contemplated by this Agreement. For purposes of this Agreement, “Superior Proposal” means any unsolicited bona fide written Takeover Proposal which (i) contemplates (A) a merger or other business combination, reorganization, share exchange, recapitalization, liquidation, dissolution, tender offer, exchange offer or similar transaction involving the Company as a result of which the Company’s stockholders prior to such transaction in the aggregate cease to own at least 20% of the voting securities of the ultimate parent entity resulting from such transaction, or (B) a sale, lease, exchange, transfer or other disposition (including, without limitation, a contribution to a joint venture) of at least 10% of the value of the net assets of the Company, taken as a whole, and (ii) is on terms which the board of directors of the Company determines (after consultation with its financial advisor and outside counsel), taking into account, among other things, all legal, financial, regulatory and other aspects of the proposal and the person making the proposal, (A) would, if consummated, result in a transaction that is more favorable to its stockholders from a financial point of view (in their capacities as such) than the transactions contemplated by this Agreement (including the terms of any proposal by Parent to modify the terms of the transactions contemplated by this Agreement), and (B) is reasonably likely to be financed and otherwise completed without undue delay.

(d) The Company agrees that it will, and will cause its officers, employees, directors, agents and representatives to, immediately cease any activities, discussions or negotiations existing as of the date of this Agreement with any parties conducted heretofore with respect to any Takeover Proposal and will use its reasonable best efforts to cause any such parties (and its agents or advisors) in possession of confidential information regarding the Company that was furnished by or on behalf of the Company to return or destroy all such information. The Company shall use its reasonable best efforts to ensure that its officers, directors and representatives are aware of the provisions of this Section 5.9.

5.10 Section 16 Matters.

5.11 Voting Agreement. The Company and Parent acknowledge and agree that Parent and those officers and directors of Parent who hold Company Common Stock, and the Company, have entered, or will enter, into a Voting Agreement providing that at the Shareholders’ Meeting, Parent (and those officers and directors of Parent who hold Company Common Stock) shall vote all of its and their Company Common Stock in the same manner (for, or against, the Merger) as voted by the holders of a majority of the shares of Company Common Stock not owned by Parent.

5.14 Indemnification. Parent agrees that, for a period of six years following the Effective Date, Parent shall defend, protect, indemnify and hold harmless each of the Company’s officers and directors (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith, including threatened actions, causes of action, suits or claims, hereafter an “Action” (irrespective of whether any such Indemnitee is a party to such action or other proceeding for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by the Indemnitees or any of them as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in this Agreement or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in this Agreement or any other certificate, instrument or document contemplated hereby or thereby, or (c) any Action brought or made against such Indemnitee arising out of or resulting from the execution, delivery, performance or enforcement of this Agreement or any other instrument, document or agreement executed pursuant hereto. To the extent that the foregoing indemnification may be unenforceable for any reason, including but not limited to policies of the SEC, Parent shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under law. The obligations of the parties to indemnify or make contribution under this Section 5.14 shall survive termination.
