THIS AGREEMENT AND PLAN OF MERGER, dated as of September 19, 2008 (this “Agreement”), is entered into by and among Constellation Energy Group, Inc., a Maryland corporation (the “Company”), MidAmerican Energy Holdings Company, an Iowa corporation (the “Parent”), and MEHC Merger Sub Inc., a Maryland corporation and a wholly owned subsidiary of Parent (the “Merger Sub”).

WHEREAS, the Company and the Parent have determined that it would be in each of their best interests and in the best interests of their respective shareholders, to effect the transactions contemplated by this Agreement;

WHEREAS, in furtherance thereof, the respective Boards of Directors of the Company, the Parent and the Merger Sub have approved this Agreement and the merger of the Merger Sub with and into the Company whereby the Company will become a wholly owned subsidiary of the Parent (the “Merger”); and

WHEREAS, contemporaneously with the execution and delivery of this Agreement, the parties hereto shall enter into a Series A Convertible Preferred Stock Purchase Agreement (the “Securities Purchase Agreement”) and an Investor Rights Agreement (the “▇▇▇” and, collectively with the Securities Purchase Agreement, the “Purchase Agreement”).

NOW, THEREFORE, in consideration of the premises and the representations, warranties, covenants and agreements contained herein, the parties hereto, intending to be legally bound hereby, agree as follows:

ARTICLE I.

THE MERGER

Section 1.1. The Merger. Upon the terms and subject to the conditions of this Agreement, at the Effective Time (as defined in Section 1.3), the Merger Sub shall be merged with and into the Company in accordance with the laws of the State of Maryland and the separate existence of the Merger Sub shall cease. The Company shall be the Surviving Corporation (as defined below) in the Merger, shall continue its corporate existence under the laws of the State of Maryland and, following the Effective Time, the Company shall become a wholly owned subsidiary of the Parent and shall succeed to and assume all of the rights and obligations of the Merger Sub in accordance with the Maryland General Corporation Law, as amended (the “MGCL”). The effects and consequences of the Merger shall be as set forth in Section 1.2. The surviving corporation after the Merger is sometimes referred to herein as the “Surviving Corporation.”

Section 1.2. Effects of the Merger. At the Effective Time, (a) the charter of the Company in effect immediately prior to the Effective Time shall at the Effective Time be amended in its entirety to be the same as charter of the Merger Sub, as in effect immediately prior to the Effective Time, except that the name of the corporation shall be “Constellation Energy Group, Inc.”, and as so amended in its entirety shall be set forth on Attachment A to the Articles of Merger (as defined below) and shall be the charter of the Surviving Corporation until thereafter duly amended and (b) the Merger shall have all of the effects provided by the MGCL.

As of the Effective Time, each of the directors of the Company shall resign and the directors of the Merger Sub at the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation until their successors have been duly elected and qualified or until their earlier death, resignation or removal in accordance with the MGCL and the charter of the Surviving Corporation.

Section 1.3. Effective Time of the Merger. Subject to the provisions of this Agreement, on the Closing Date (as defined in Section 3.1), articles of merger in a form mutually agreed by the parties (the “Articles of Merger”) shall be executed and filed by the Company and the Merger Sub with the State Department of Assessments and Taxation of Maryland (“SDAT”) pursuant to the MGCL. The Merger shall become effective upon the filing of the Articles of Merger with, and the acceptance of the Articles of Merger for record by, the SDAT or upon the effective time specified in Articles of Merger so filed, whichever is later (the “Effective Time”).

ARTICLE II.

TREATMENT OF SHARES

Section 2.1. Effect on Stock of the Company and the Merger Sub. As of the Effective Time, by virtue of the Merger and without any action on the part of any holder of any of the capital stock of the Company or the Merger Sub:

(a) Conversion of Stock of the Company. Each share of common stock, without par value, of the Company (the “Company Common Stock”) issued and outstanding as of the Effective Time (other than shares of Company Common Stock to be treated in accordance with Section 2.1(b)), shall be converted into the right to receive cash in the amount of $26.50 per share (the “Merger Consideration”), payable, without interest, to the holder of such share of Company Common Stock, upon surrender, in accordance with Section 2.3 hereof, of the certificate formerly representing such share.

(b) Treatment of Certain Shares of Company Common Stock. Each share of Company Common Stock that is owned by the Parent or by any wholly owned Subsidiary (as defined in Section 4.1) of the Company or the Parent, in each case immediately prior to the Effective Time, shall remain outstanding and shall become that number of shares of common stock of the Surviving Corporation that bears the same ratio to the aggregate number of outstanding shares of the Surviving Corporation as the number of shares of Company Common Stock held by such entity bore to the aggregate number of outstanding shares of Company Common Stock immediately prior to the Effective Time.

(c) Stock of the Merger Sub. Each share of common stock, par value $0.01 per share, of the Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of the Surviving Corporation, which shall thereafter (together with the shares of common stock of the Surviving Corporation issued in accordance with Section 2.1(b)) constitute all of the issued and outstanding shares of common stock of the Surviving Corporation. No capital stock of the Merger Sub will be issued or used in the Merger.

- 2 -

Section 2.2. Surrender of Certificates.

(a) Deposit with Paying Agent. Prior to the Effective Time, the Parent shall designate a bank or trust company that is reasonably acceptable to the Company to act as agent (the “Paying Agent”) for the holders of shares of Company Common Stock in connection with the Merger to receive the funds to which holders of shares of Company Common Stock shall become entitled pursuant to Section 2.1(a). Such funds shall be deposited with the Paying Agent by the Parent immediately prior to or after the Effective Time and shall be invested by the Paying Agent as directed by the Parent; provided that, no investment of such deposited funds shall relieve the Parent, the Surviving Corporation or the Paying Agent from promptly making the payments required by this Article II, and following any losses from any such investment, the Parent shall promptly provide additional funds to the Paying Agent for the benefit of the holders of shares of Company Common Stock at the Effective Time in the amount of such losses, which additional funds will be held and disbursed in the same manner as funds initially deposited with the Paying Agent for payment of the Merger Consideration to holders of shares of Company Common Stock.

(b) Exchange Procedures. As soon as practicable after the Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates (the “Certificates”) which as of the Effective Time represented outstanding shares of Company Common Stock (the “Cancelled Shares”) that were converted into the right to receive the Merger Consideration pursuant to Section 2.1: (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon actual delivery of the Certificates (or affidavits of loss in lieu thereof) or book-entry shares (“Book-Entry Shares”) to the Paying Agent and such other provisions upon which the Parent and the Company may agree) and (ii) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu thereof) and Book-Entry Shares in exchange for the Merger Consideration. Upon surrender of a Certificate (or an affidavit of loss in lieu thereof) or Book-Entry Shares to the Paying Agent for cancellation (or to such other agent or agents as may be appointed by mutual agreement of the Parent and the Company), together with a duly executed letter of transmittal and such other documents as the Paying Agent may require, the holder of such Certificate or Book-Entry Shares shall be entitled to receive the Merger Consideration (after giving effect to any required tax withholdings as provided in Section 2.4) in exchange for each share of Company Common Stock formerly evidenced by such Certificate or Book-Entry Shares, which such holder has the right to receive pursuant to the provisions of this Article II. In the event of a transfer of ownership of Cancelled Shares which is not registered in the transfer records of the Company, the Merger Consideration may be delivered to a transferee if the Certificate (or affidavit of loss in lieu thereof) or Book-Entry Shares representing such Cancelled Shares is presented to the Paying Agent accompanied by all documents required to evidence and effect such transfer and by evidence satisfactory to the Paying Agent that any applicable Transfer Taxes (as defined in Section 7.13) have been paid. Until surrendered as contemplated by this Section 2.2, each Certificate (or affidavit of loss in lieu thereof) and Book-Entry Shares shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration as contemplated by this Section 2.2. No interest shall be paid or will accrue on the Merger Consideration payable to holders of Certificates or Book-Entry Shares pursuant to the provisions of this Article II.

- 3 -

(c) Closing of Transfer Books; Rights of Holders of Company Common Stock. From and after the Effective Time, the Company Common Stock transfer books shall be closed and no registration of any transfer of such stock shall thereafter be made on the records of the Company. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation, they shall be cancelled and exchanged for the Merger Consideration, as provided in this Section 2.2. From and after the Effective Time, the holders of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock, except as otherwise provided herein or by any applicable domestic or foreign laws, statutes, ordinances, rules (including rules of common law), regulations, codes, executive orders or legally enforceable requirements enacted, issued, adopted, promulgated or applied by any Governmental Authority (each, a “Law”).

(d) Termination of Paying Agent. At any time commencing six months after the Effective Time, the Parent shall be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of shares of Company Common Stock (including, without limitation, all interest and other income received by the Paying Agent in respect of all funds made available to it), and thereafter such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar Laws) only as general creditors thereof with respect to any Merger Consideration that may be payable upon due surrender of the Certificates held by them. Notwithstanding the foregoing, neither the Parent, the Surviving Corporation nor the Paying Agent shall be liable to any holder of a share of Company Common Stock for any Merger Consideration delivered in respect of such share to a public official pursuant to any abandoned property, escheat or other similar Law.

(e) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder of shares of Company Common Stock claiming such Certificate to be lost, stolen or destroyed and, if required by the Parent, the posting by such holder of a bond in customary amount and upon such terms as may be required by the Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will pay the Merger Consideration (after giving effect to any required tax withholdings as provided in Section 2.4) to such holder in exchange for such lost, stolen or destroyed Certificate.

Section 2.3. Treatment of Company Stock Awards.

(a) Options. Prior to the Effective Time, the Company shall take all actions necessary to provide, effective as of the Effective Time, for the cancellation, on the terms and conditions set forth in this Section 2.3 and without any payment therefor except as otherwise provided in this Section 2.3, of all Company Employee Stock Options (as defined in Section 4.3(a)) (whether or not then exercisable) on Company Common Stock outstanding at the Effective Time. As of the Effective Time, each such Company Employee Stock Option (whether vested or unvested) shall be cancelled (and to the extent formerly so exercisable shall no longer be exercisable) and shall entitle each holder thereof, in cancellation and settlement therefor, to receive a payment, if any, in cash from the Company (less any applicable withholding taxes), promptly following the Effective Time, equal to (i) the amount, if any, by which the Merger

- 4 -

Consideration exceeds the exercise price per share with respect to such Company Employee Stock Options, multiplied by (ii) the total number of shares of Company Common Stock then issuable upon the exercise of such Company Employee Stock Options (whether or not then vested or exercisable).

(b) Other Awards. Prior to the Effective Time, the Company shall take all actions necessary to provide, effective as of the Effective Time, for the cancellation, on the terms and conditions set forth in this Section 2.3(b) and without any payment therefor except as otherwise provided in this Section 2.3(b), of each award (the “Company Awards”) (including each share of Company Restricted Stock, and each Company Restricted Unit, stock equivalent and Company Performance Unit, but excluding Company Employee Stock Options) outstanding immediately before the Effective Time. As of the Effective Time, each such Company Award shall be cancelled and shall entitle each holder thereof, in cancellation and settlement therefor, to receive a payment in cash from the Company (less any applicable withholding taxes), promptly following the Effective Time, equal to (i) the Merger Consideration, multiplied by (ii) the total number of shares of Company Common Stock that would be issuable upon full vesting of such award or for which restrictions would lapse upon full vesting of such award; provided, that, notwithstanding anything in this sentence to the contrary, in the case of Company Performance Units, each outstanding Company Performance Unit that becomes vested at the Effective Time pursuant to the terms of the applicable Company Stock Plan (based upon the number of months from the start of the applicable performance period to the Effective Time) shall immediately vest at the Effective Time, with the holder of each such Company Performance Unit becoming entitled to receive, in full satisfaction of the rights of such holder with respect to such award (including any portion that remains unvested), an amount in cash equal to $2.00 (provided that (A) amounts payable pursuant to the cancellation of all outstanding Company Performance Units pursuant to this sentence shall be paid out within 30 days after the Effective Time without interest and (B) each outstanding Company Performance Unit that does not become vested at the Effective Time pursuant to the terms of the applicable Company Stock Plan shall expire at the Effective Time and the holder thereof shall be entitled to no further payments or benefits with respect thereto.

(c) Required Action. At or prior to the Effective Time, the Company, the Board of Directors of the Company and the compensation committee of the Board of Directors of the Company, as applicable, shall adopt any resolutions and take any actions, including obtaining consents and acknowledgements of participants, which are necessary to effectuate the provisions of Section 2.3(a), (b) and (c). The Company shall take all commercially reasonable actions to ensure that from and after the Effective Time neither the Parent nor the Surviving Corporation will be required to deliver Company Common Stock or other capital stock of the Company to any Person pursuant to or in settlement of Company Employee Stock Options or Company Awards. The Company shall also take all action reasonably necessary to approve the disposition of the Company Employee Stock Options or Company Awards in accordance with this Section 2.3 so as to exempt such dispositions under Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Section 2.4. Withholding Rights. Other than in respect of Transfer Taxes, which shall be governed by Section 7.13, each of the Surviving Corporation, the Company, the Parent and the Paying Agent shall be entitled to deduct and withhold from the Merger Consideration or

- 5 -

other payments made pursuant to this Agreement to any holder of shares of Company Common Stock, Company Employee Stock Options or Company Awards or other Person (as defined below) such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder, or any provision of state, local or foreign Tax (as defined in Section 4.9) Law. To the extent that amounts are so withheld by the Surviving Corporation, the Company, the Parent or the Paying Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock, Company Employee Stock Options or Company Awards or other Person in respect of which such deduction and withholding was made by the Surviving Corporation, the Company, the Parent or the Paying Agent, as the case may be. As used in this Agreement, the term “Person” shall mean any natural person, corporation, general or limited partnership, limited liability company, joint venture, trust, association or entity of any kind.

Section 2.5. Adjustments to Prevent Dilution. In the event that the Company changes the number of shares of Company Common Stock or securities convertible or exchangeable into or exercisable for Company Common Stock issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer, or other similar transaction, the Merger Consideration shall be equitably adjusted.

ARTICLE III.

Section 3.1. Closing. The closing of the Merger (the “Closing”) shall take place at the offices ▇▇▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ at 10:00 a.m., local time, on the third business day immediately following the date on which the last of the conditions set forth in Article VIII hereof is fulfilled or waived (other than any conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions at the Closing), or at such other time, date and place as the Company and the Parent shall mutually agree (the “Closing Date”).

- 6 -

in any risk factor section, in any forward looking statements (whether or not specifically identified as such), including future operating results and any other disclosures included thereon to the extent that they are cautionary, precatory or forward-looking in nature (provided that this clause (ii) shall not apply to Sections 4.1, 4.2, 4.3, 4.4(a), (b), (c) and (e), 4.16(b)(iii), 4.19, 4.20, 4.22, 4.24 and 4.26):

Section 4.1. Organization and Qualification. The Company and each of the Company Subsidiaries (as defined below) and each Company Joint Venture (as defined in Section 4.2(c)(B)) is a corporation, limited liability company or limited partnership duly organized, validly existing and in good standing, as applicable, under the Laws the jurisdiction set forth opposite its name in Section 4.2 of the Disclosure Letter. The Company and each of the Company Subsidiaries and each Company Joint Venture has all requisite power and authority to own, lease and operate its assets and properties to the extent owned, leased and operated and to carry on its business as it is now being conducted and is duly qualified and in good standing to do business in each jurisdiction in which the nature of its business or the ownership or leasing of its assets and properties makes such qualification necessary other than in such jurisdictions where the failure to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to result in a Company Material Adverse Effect (as defined below).

If at any time prior to the Effective Time any information relating to the Company, the Parent or the Merger Sub, or any of their respective Affiliates, officers or directors, should be discovered by the Company, the Parent or the Merger Sub which should be set forth in an amendment or supplement to the Proxy Statement, so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the shareholders of the Company.

(a) Approvals. Upon the terms and subject to the conditions set forth in this Agreement and in accordance with applicable Laws, each of the parties to this Agreement will use all reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to ensure that the conditions set forth in Article VIII are satisfied and to consummate the transactions contemplated by this Agreement as promptly as practicable, including (i) obtaining all necessary actions or nonactions, waivers, consents and approvals from Governmental Authorities and making all necessary registrations and filings and taking all steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Authority, (ii) making, as promptly as practicable (and in any event within 10 business days of the date hereof), an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby, (iii) making, as promptly as practicable, appropriate filings with other Governmental Authorities necessary or advisable to obtain the Company Required Statutory Approvals and the Parent Required Statutory Approvals; provided, however, that the Company and the Parent shall file the Company Required Statutory Approvals and the Parent Required Statutory Approvals, respectively, as promptly as is reasonably practicable after the date hereof, (iv) responding on a timely basis to any request for additional information from any Governmental Authority and (v) obtaining all consents, approvals or waivers from, or taking other actions with respect to, third parties (other than Governmental Authorities) necessary or advisable to be obtained or taken in connection with the transactions contemplated by this Agreement; provided that the Company shall not (and it shall not permit any Company Subsidiary or Company Joint Venture to pay, incur or become subject to any liability or commitment in respect of obtaining any such consent, approval or waiver such that, when such liability or commitment is added to all other such liabilities or commitments, the aggregate of the same exceeds $5 million. Each party shall have the right to review a reasonable time in advance and to provide comments on any filing (including any material amendments thereto) made after the date hereof and until the Initial Termination Date (as the same may be extended hereunder) by the other party or a Subsidiary (or, in the case of the Company, Joint Venture) of any party with any Governmental Authority with respect to the Merger and the party or Subsidiary making such filing shall give reasonable consideration to any changes suggested for such filing. In addition, the Company shall consult with the Parent prior to making any regulatory filing (including any material amendments

- 41 -

thereto) with the MPSC, NRC or FERC, except for routine filings made in the ordinary course of business consistent with past practice, provided that a general rate case will not be considered a routine filing for purposes of this Section 7.3(b), and provided that the Company will consult with the Parent regarding specific routine filings as reasonably requested by the Parent, and to keep the Parent reasonably informed about material developments and requests from the MPSC, NRC or FERC with respect to such filings; provided, however, that in connection with any such consultation the Parent shall not be entitled to direct or manage any decisions or activities of the Company, the Company Subsidiaries or the Company Joint Ventures. The Company shall not file any such document or take such action if the Parent has reasonably objected (and not withdrawn its objection) to the filing of such document or the taking of such action on the grounds that such filing or action would reasonably be expected to either (i) prevent, materially delay or materially impede the consummation of the transactions contemplated hereby or (ii) cause a condition set forth in Article VIII to not be satisfied in a timely manner. The Company shall not consent to any voluntary extension of any statutory deadline or waiting period or to any voluntary delay of the consummation of the transactions contemplated by this Agreement at the behest of any Governmental Authority without the consent of the Parent.

(b) The Company and the Parent each shall, upon request by the other, furnish the other with all true and accurate information concerning itself, its Subsidiaries (and in the case of the Company, the Company Joint Ventures), directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, or any other statement, filing, notice or application made by or on behalf of the Parent, the Company or any of their respective Subsidiaries (and in the case of the Company, the Company Joint Ventures) to any Governmental Authority in connection with the Merger and the transactions contemplated by this Agreement.

(c) The Company and the Parent each shall promptly provide the other party with copies of all filings made by any of the Company, the Parent or any of their Subsidiaries with any federal or state court, administrative agency, commission or other Governmental Authority in connection with this Agreement and the transactions contemplated hereby. The Company and the Parent each shall keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby, including promptly furnishing the other with copies of any notices or other communications received by the Parent or the Company, as the case may be, or any of its Subsidiaries, from any third party and/or any Governmental Authority with respect to the Merger and the other transactions contemplated by this Agreement. The Company shall give the Parent prompt notice of any change that would reasonably be expected to result in a Company Material Adverse Effect.

(d) In the event any claim, action, suit, investigation, legal or administrative proceeding is commenced by any Governmental Authority or Person (other than to the Company, the Parent or any of their Subsidiaries or the Joint Ventures) that questions the validity or legality of this Agreement, or the Merger or the other transactions contemplated by this Agreement or claims damages in connection therewith, the Company and the Parent each agree to cooperate and use their reasonable efforts to defend against and respond thereto.

- 42 -

(e) The Company, the Parent and the Merger Sub agree that the application submitted to the MPSC with respect to the Merger shall include the information concerning the Merger, the Company, the Parent and the Merger Sub required by Section 6-105 of the Public Utilities Code of the Annotated Code of Maryland and to only include such other agreements or commitments as agreed to by the Parent and the Merger Sub, in each case, whose consent to any such agreements or commitments shall not be unreasonably withheld, conditioned or delayed. The Company agrees that it will not agree to, or accept, any additional or different agreements, commitments or conditions in connection with the Merger or the transactions contemplated by the Purchase Agreement pursuant to any settlement or otherwise with the Staff of the MPSC or any other Person without the prior written consent of the Parent, which consent shall not be unreasonably withheld, conditioned or delayed, except for agreements, commitments and conditions requiring Permitted Actions. As used in this Agreement, “Permitted Actions” means any action contemplated by this Section 7.3 with respect to a Governmental Authority (collectively, “Regulatory Actions”) and whether or not requested by a Governmental Authority of the Company, the Company Subsidiaries, the Company Joint Ventures, Parent, and its Subsidiaries other than (i) any Regulatory Action of any of them, the effects of which, when combined with the effects of all other Regulatory Actions (including capital expenditures and rate reductions constituting Regulatory Actions) taken by any of them is reasonably likely to exceed in the aggregate an amount acceptable to the Parent in its reasonable discretion, in each case taken (or committed (whether or not legally committed) to be taken) after the date hereof, (ii) capital expenditures constituting Regulatory Actions of the Company, its Subsidiaries, the Company Joint Ventures, the Parent and its Subsidiaries that when combined with rate reductions of the Company, its Subsidiaries and the Company Joint Ventures, in each case made or committed (whether or not legally committed) to be made after the date hereof exceed in the aggregate an amount acceptable to the Parent in its reasonable discretion (iii) rate reductions of the Company, its Subsidiaries and the Company Joint Ventures that when combined with capital expenditures constituting Regulatory Actions of such Persons or of the Parent and its Subsidiaries, in each case made or committed (whether or not legally committed) to be made after the date hereof in the aggregate exceed an amount acceptable to the Parent in its reasonable discretion.

(f) Notwithstanding any other provision of this Agreement, the Parent and the Merger Sub shall not be required to cause Parent or any Affiliate of Parent or any director, officer, employee, general partner, limited partner, member or manager of Parent any other Affiliate of the Parent, in each case in his, her or its individual capacity, to either (A) take any action, or undertake the divestiture of any asset, property or company or (B) restrict in any more than a de minimis respect the ability of Parent or any Affiliate of Parent to exercise its rights of ownership with respect to its investment in the Parent, the Surviving Corporation or their Subsidiaries, other than Permitted Actions, and actions to provide responsive information required to make any submission or application to a Governmental Authority and to otherwise cooperate in connection with any such submission or application as is necessary and customary under the circumstances. Without the prior written consent of the Parent (which may be given or withheld in its sole discretion), the Company shall, and shall cause each Company Subsidiary and Company Joint Venture to, refrain from taking (or committing (whether or not legally committed) to take) any Regulatory Action that is not a Permitted Action and none of the Parent or its Subsidiaries shall be obligated to take (or commit (whether or not legally committed) to take) any Regulatory Action that is not a Permitted Action, anything in this Agreement to the contrary notwithstanding.

- 43 -

Section 7.4. Approval of the Company Shareholders. The Company shall, as soon as reasonably practicable, (i) take all steps necessary to duly call, give notice of, convene and hold a meeting of its shareholders (the “Company Meeting”) for the purpose of securing the Company Shareholders’ Approval and in any event the Company Meeting shall be held within forty-five (45) days following the earlier of SEC approval of the Proxy Statement or if the SEC does not review the Proxy Statement, the earliest date on which the Company could mail the Proxy Statement pursuant to the Exchange Act, (ii) distribute to its shareholders the Proxy Statement in accordance with applicable federal and state Law and with its articles of incorporation and by-laws, (iii) subject to Section 7.8, recommend to its shareholders the approval of the Merger, this Agreement and the transactions contemplated hereby, (iv) use all reasonable efforts to solicit or cause to be solicited from its shareholders proxies in favor of adoption of this Agreement, (v) subject to Section 7.8, take all other reasonable action necessary to secure the Company Shareholders’ Approval and (vi) cooperate and consult with the Parent with respect to each of the foregoing matters. Notwithstanding anything herein to the contrary, unless this Agreement is terminated in accordance with Section 9.1, the Company will take all of the actions contemplated by this Section 7.4 regardless of whether the Board of Directors of the Company has approved, endorsed or recommended another Takeover Proposal (is defined in Section 7.8(e)(iii)) or has withdrawn, modified or amended the Company Board Recommendation, and will submit this Agreement for adoption by the shareholders of the Company at such meeting. The Company shall keep the Parent updated with respect to the proxy solicitation results as reasonably requested by Parent.

Section 7.5. Directors’ and Officers’ Indemnification.

(a) Indemnification. From and after the Effective Time, the Surviving Corporation shall, to the fullest extent permitted by applicable Law, indemnify, defend and hold harmless each current or former director, officer, employee or fiduciary under benefit plans of the Company and its Subsidiaries (each an “Indemnified Party” and collectively, the “Indemnified Parties”) against (i) all losses, expenses (including reasonable attorney’s fees and expenses), claims, damages or liabilities or, subject to the proviso of the next succeeding sentence, amounts paid in settlement, arising out of actions or omissions occurring at or prior to the Effective Time (and whether asserted or claimed prior to, at or after the Effective Time) to the extent that they are based on or arising out of the fact that such Person is or was a director, officer, employee or fiduciary under benefit plans (the “Indemnified Liabilities”), and (ii) all Indemnified Liabilities to the extent they are based on or arise out of or pertain to the transactions contemplated by this Agreement, in each case only to the extent such Person has a right to indemnification from the Company or the Company Subsidiaries immediately before the Effective Time. In the event of any such loss, expense, claim, damage or liability (whether or not asserted before the Effective Time), (i) the Surviving Corporation shall pay the reasonable fees and expenses of counsel selected by the Indemnified Parties, which counsel shall be reasonably satisfactory to the Surviving Corporation, promptly after statements therefor are received and otherwise advance to such Indemnified Party upon request, reimbursement of documented expenses reasonably incurred, in either case to the extent not prohibited by the business corporation Law of the Surviving Corporation’s state of incorporation, (ii) the Surviving Corporation and the Indemnified Parties will cooperate in the defense of any such matter and (iii) any determination required to be made with respect to whether an Indemnified Party’s conduct complies with the standards set forth under the business corporation Law of the

- 44 -

Surviving Corporation’s state of incorporation and the articles of incorporation or by-laws of the Surviving Corporation shall be made by independent counsel mutually acceptable to the Surviving Corporation and the Indemnified Party; provided, however, that the Surviving Corporation shall not be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld). The Indemnified Parties as a group may retain only one law firm with respect to each related matter except to the extent there is, in the opinion of counsel to an Indemnified Party, under applicable standards of professional conduct, a conflict on any significant issue between positions of such Indemnified Party and any other Indemnified Party or Indemnified Parties.

(b) Insurance. The Parent shall cause the Surviving Corporation either (i) to maintain in effect for the six-year period commencing immediately after the Effective Time (and for so long thereafter as any claims brought before the end of such six-year period thereunder are being adjudicated) the Company’s current directors’ and officers’ liability insurance (the “Existing D&O Coverage”) covering acts or omissions occurring at or prior to the Effective Time with respect to those individuals who are as of the date hereof (and any additional individuals who prior to the Effective Time become) covered by the Company’s directors’ and officers’ liability insurance policy on terms with respect to such coverage, and in amount, no less advantageous to the intended beneficiaries thereof than those of such policy in effect on the date hereof (or the Parent may cause the Surviving Corporation to substitute therefor policies, issued by reputable insurers, of at least the same coverage with respect to matters occurring prior to the Effective Time); provided that if the aggregate annual premiums for such insurance shall exceed 150% of the aggregate annual premiums paid by the Company as of the date hereof, then the Parent shall cause the Surviving Corporation to provide or cause to be provided a policy for the applicable individuals with the best coverage as shall then be available at an annual premium of 150% of the current aggregate annual premium or (ii) to purchase a six-year extended reporting period endorsement (“reporting tail coverage”) under the Existing D&O Coverage, provided that such reporting tail coverage shall extend the director and officer liability coverage in force as of the date hereof from the Effective Time on terms, that in all material respects, are no less advantageous to the intended beneficiaries thereof than the existing directors’ and officers’ liability insurance.

(c) Successors. In the event the Surviving Corporation, the Parent or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either such case, proper provisions shall be made so that the successors, assigns and/or transferees of the Surviving Corporation or the Parent shall assume the obligations set forth in this Section 7.5; provided that this Section 7.5(c) shall no longer apply to the Parent if reporting tail coverage meeting the requirements of Section 7.5(b) shall have been purchased by the Surviving Corporation.

(d) Survival of Indemnification. To the fullest extent permitted by Law, from and after the Effective Time, all rights to indemnification as of the date hereof in favor of the employees, agents, directors and officers of the Company, the Company Subsidiaries with respect to their activities as such prior to, on or after the Effective Time, as provided in their respective articles of incorporation and by-laws in effect on the date thereof, or otherwise in

- 45 -

effect on the date hereof, shall survive the Merger and shall continue in full force and effect for a period of not less than six (6) years from the Effective Time, provided that, in the event any claim or claims are asserted or made within such survival period, all such rights to indemnification in respect to any claim or claims shall continue until final disposition of such claim or claims.

(e) Benefit. The provisions of this Section 7.5 are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs, executors or administrators and his or her representatives.

Section 7.6. Public Announcements. Except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange, the Company and the Parent shall consult with each other prior to issuing any press releases or otherwise making public announcements with respect to the Merger and the other transactions contemplated by this Agreement. Each of the Company and the Parent will, to the extent practicable, provide the other, reasonably in advance of its use, with drafts of any press release or other widely disseminated presentation or other information, in each case relating to the Merger or material corporate and financial information relating to the Company, and give reasonable consideration to the comments of the other thereon. In connection with the foregoing, the Company and the Parent may share any such drafts with their respective investors and Representatives provided that any such investors or Representatives are bound by an obligation to maintain the confidentiality of such information sufficient to satisfy the requirements of Regulation FD promulgated under the Securities Act. Each of the Company and the Parent will advise the other in advance of the timing of any such press release, presentation or other information relating to the Merger and will provide the other with a final copy of the same simultaneously with its public release.

Section 7.7. Employees and Employee Benefits.

(a) Parent Agreements. Except as set forth below in this Section 7.7(a), the Parent agrees that all employees of the Company or its Subsidiaries who continue employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation after the Effective Time (“Affected Employees”) will be eligible to participate in either, at the sole discretion of Parent: (i) Parent’s employee benefit plans and programs, in each case to the same extent as similarly situated employees of Parent; or (ii) such Company Plans as are continued by the Company or any of its Subsidiaries following the Closing Date, or are assumed by Parent (for the purposes of this Section 7.7 only, the plans referred to in clauses “(i)” and “(ii)” of this sentence being referred to as “Specified Parent Benefit Plans”); provided, however, that nothing contained herein shall be construed as requiring the Parent or the Company to continue any specific plan or as preventing the Parent or the Company from (i) establishing and, if necessary, seeking shareholder approval to establish, any other benefit plans in respect of all or any of the employees covered by such Specified Parent Benefit Plans or any other employees, (ii) amending such Specified Parent Benefit Plans (or any replacement benefit plans thereof) where required by applicable Law including, without limitation, any amendments necessary to avoid application of Section 409A of the Code, or where such amendment is with the consent of the affected employees or as otherwise effected in accordance with the terms of such plans, or (iii) amending the Specified Parent Benefit Plans in the ordinary course of business. Notwithstanding the

- 46 -

foregoing, from and after the Closing Date, the Parent shall cause the Company and the Company Subsidiaries to honor, in accordance with its express terms, each existing collective bargaining, employment, change of control, severance and termination agreement between the Company or any of its Subsidiaries, and any representative union, officer, director or employee of such company and vacation entitlements already accrued as of the Closing Date.

(b) Service Credit. Subject to obligations under applicable Law and applicable collective bargaining agreements, the Parent shall cause all Affected Employees to be credited with all service for the Company or the Company Subsidiaries (and all other service credited by the Company or the Company Subsidiary or the Company Plans), under (x) all Specified Parent Benefit Plans in which Affected Employees become eligible to participate on or after the Effective Time, for purposes of eligibility, vesting, benefit accrual and all other purposes (but not for purposes of benefit accrual under defined benefit pension plans or eligibility for early retirement under defined benefit pension plans and not to the extent crediting such service would result in duplication of benefits). The Parent shall, and shall cause its direct and indirect Subsidiaries (including the Surviving Corporation), or shall use its reasonable efforts to cause its insurance carrier, to, (i) waive all limitations as to preexisting conditions exclusions and all waiting periods with respect to participation and coverage requirements applicable to each Affected Employee under any Specified Parent Benefit Plan that is a welfare benefit plan in which an Affected Employee becomes eligible to participate on or after the Effective Time, except to the extent of limitations or waiting periods that are already in effect under the Company Plans with respect to the Affected Employee as of the Effective Time and that have not been satisfied as of the Effective Time and (ii) credit each Affected Employee for any co-payments, deductibles and other out-of-pocket expenses paid prior to the Effective Time in satisfying any applicable deductible, co-payment or out-of-pocket requirements for the year in which the Effective Time occurs under any Specified Parent Benefit Plan that is welfare plan in which the Affected Employee participates on and after the Effective Time. Nothing in this Section 7.7 shall be deemed to create any third-party beneficiary or right of employment with respect to any Affected Employee. Nothing contained in this Agreement shall constitute or be deemed to be an amendment to any Specified Parent Benefit Plan or any other compensation or benefit plan, program or arrangement of the Parent, Surviving Corporation, Company or any Company Subsidiary.

(c) Communications. Prior to making any material written communications to the directors, officers or employees of the Company or any of its Subsidiaries, or material oral communications to a group of directors, officers or employees, pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement, the Company shall provide the Parent with a copy of the intended communication, the Parent shall have a reasonable period of time to review and comment on the communication, and the Parent and the Company shall cooperate in providing any such mutually agreeable communication.

Section 7.8. No Solicitation.

(a) From the date of this Agreement until the Effective Time, except as specifically permitted in Section 7.8(d), the Company agrees that none of it, any of its Subsidiaries or the Company Joint Ventures nor any of the officers or directors of the Company,

- 47 -

its Subsidiaries or the Company Joint Ventures shall, and that it shall cause its, its Subsidiaries’ and its Joint Ventures’ Representatives not to, directly or indirectly:

(i) initiate, solicit or encourage (including by way of providing information) or facilitate any inquiries, proposals or offers with respect to, or the making, or the completion of, a Takeover Proposal;

(ii) participate or engage in any discussions or negotiations with, or furnish or disclose any non-public information relating to the Company, any of its Subsidiaries or any of the Company Joint Ventures to, or otherwise cooperate with or assist any Person in connection with a Takeover Proposal;

(iii) withdraw, modify or amend the Company Board Recommendation in any manner adverse to the Parent or Merger Sub;

(iv) approve, endorse or recommend any Takeover Proposal;

(v) enter into any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to a Takeover Proposal; or

(vi) resolve, propose or agree to do any of the foregoing.

(b) The Company shall, and shall cause each of its Subsidiaries, Joint Ventures and Representatives to, immediately cease any existing solicitations, discussions or negotiations with any Person (other than the parties hereto) that has made or indicated an intention to make a Takeover Proposal. The Company shall promptly request that each Person who has executed a confidentiality agreement with the Company in connection with such Person’s consideration of a Takeover Proposal (other than the parties hereto and their respective advisors) return or destroy all non-public information furnished to that Person by or on behalf of the Company, any of the Company Subsidiaries or any of the Company Joint Ventures. The Company shall promptly inform its Representatives of the Company’s obligations under this Section 7.8.

(c) The Company shall notify the Parent promptly (and in any event within 24 hours) upon receipt by it, any of its Subsidiaries, Company Joint Ventures or Representatives of (i) any Takeover Proposal or indication by any Person that it is considering making a Takeover Proposal, (ii) any request for non-public information relating to the Company, any of its Subsidiaries or any of the Company Joint Ventures other than requests for information in the ordinary course of business and unrelated to a Takeover Proposal or (iii) any inquiry or request for discussions or negotiations regarding any Takeover Proposal. The Company shall notify Parent promptly (and in any event within 24 hours) with the identity of such Person and a copy of such Takeover Proposal, indication, inquiry or request (or, where no such copy is available, a description of such Takeover Proposal, indication, inquiry or request), including any modifications thereto. The Company shall keep the Parent reasonably informed on a current basis (and in any event within 24 hours of the occurrence of any changes, developments, discussions or negotiations) of the status of any such Takeover Proposal, indication, inquiry or request (including the material terms and conditions thereof and of any modification thereto),

- 48 -

and any material developments, discussions and negotiations, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting the foregoing, the Company shall promptly (and in any event within 24 hours) notify the Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning a Takeover Proposal pursuant to this Section 7.8(d). The Company shall not, and shall cause its Subsidiaries and Company Joint Ventures not to, enter into any confidentiality agreement with any Person subsequent to the date of this Agreement, and none of the Company, nor any of its Subsidiaries or any of the Company Joint Ventures, is party to any agreement, which prohibits the Company from providing such information to the Parent. The Company shall not, and shall cause each of its Subsidiaries and Company Joint Ventures not to, terminate, waive, amend or modify any provision of any existing standstill or confidentiality agreement to which it or any of its Subsidiaries or any Company Joint Venture is a party, and the Company shall, and shall cause its Subsidiaries and Company Joint Ventures to, enforce the provisions of any such agreement; provided, however, that the Company shall have the right to, and to cause each of its Subsidiaries and Company Joint Ventures to, waive in writing any standstill solely to the extent required to permit such a Person to convey confidentially a Takeover Proposal to the Board of Directors of the Company under circumstances in which the Company is permitted under this Section 7.8 to participate in discussions regarding a Takeover Proposal. In the event that the Company, its Subsidiaries or the Company Joint Ventures waive any standstill provision, the Company shall simultaneously give written notice of such waiver to the Parent. If requested in writing by the Parent at least three (3) business days prior to the Company Meeting, the Board of Directors of the Company shall, prior to the Company Meeting, publicly reaffirm the Company Board Recommendation and any failure to do so shall be deemed to be a change in the Company Board Recommendation that permits Parent to terminate this Agreement pursuant to Section 9.1(g).

action would be reasonably likely to result in a breach of its duties to the Company and its stockholders under applicable Laws, but only so long as the Company (x) has caused such Person to enter into an Acceptable Confidentiality Agreement and (y) concurrently discloses the same such non-public information to the Parent if such non-public information has not previously been disclosed to the Parent; and

(iii) withdraw, modify or amend the Company Board Recommendation in a manner adverse to the Parent or Merger Sub, if the Board of Directors of the Company has determined in good faith, after receiving the advice of outside legal counsel, that the failure to take such action would be reasonably likely to result in a breach of its duties to the Company and its stockholders under applicable Laws; provided that prior to any such withdrawal, modification or amendment to the Company Board Recommendation, (A) the Company shall have given the Parent prompt written notice advising the Parent of (x) the decision of the Board of Directors of the Company to take such action and the reason for taking such action and (y) in the event the decision relates to a Takeover Proposal, the material terms and conditions of the Takeover Proposal, including the identity of the party making such Takeover Proposal and, if available, a copy of the relevant proposed transaction agreements with such party and other material documents, (B) the Company shall have given the Parent five Business Days after delivery of each such notice to propose revisions to the terms of this Agreement (or make another proposal) and shall have negotiated in good faith with the Parent with respect to such proposed revisions or other proposal, if any, and (C) the Board of Directors of the Company shall have determined in good faith, after considering the results of such negotiations and giving effect to the proposals made by the Parent, if any, and after receiving the advice of outside legal counsel that the failure to effect such withdrawal, modification or amendment of the Company Board Recommendation would be reasonably likely to result in a breach of its duties to the Company and its stockholders under applicable Laws; provided that, in the event the Board of Directors of the Company does not make the determination referred to in clause (C) of this paragraph but thereafter determines to withdraw, modify or amend the Company Board Recommendation pursuant to this Section 7.8(d)(iii), the procedures referred to in clauses (A), (B) and (C) above shall apply anew and shall also apply to any subsequent withdrawal, amendment or modification.

This Section 7.8(d) shall not prohibit the Board of Directors of the Company from disclosing to the shareholders of the Company a position contemplated by Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act (other than any disclosure prohibited by Section 7.8(d)); provided, however, that any disclosure other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act shall be deemed to be a withdrawal, modification or amendment of the Company Board Recommendation in a manner adverse to the Parent or Merger Sub unless the Board of Directors of the Company (x) expressly reaffirms its recommendation to its shareholders in favor of adoption of this Agreement or, (y) rejects such other Takeover Proposal.

Section 10.4. Severability. Any term or provision of this Agreement that is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the parties agree that the court making such determination shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

Section 10.5. Interpretation. When a reference is made in this Agreement to Sections or Exhibits, such reference shall be to a Section or Exhibit of this Agreement, respectively, unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Upon any such permitted assignment, the references in this Agreement to the Parent shall also apply to any such assignee unless the context otherwise requires.

Section 10.12. Remedies.

(a) Damages. Except as otherwise provided in this Agreement, any and all remedies expressly conferred upon a party to this Agreement will be cumulative with, and not exclusive of, any other remedy contained in this Agreement, at Law or in equity. Except as otherwise provided in this Agreement, the exercise by a party to this Agreement of any one

- 61 -

remedy will not preclude the exercise by it of any other remedy. The Company agrees that, notwithstanding anything herein to the contrary (other than the last sentence of this Section 10.12(a)), (i) to the extent it has incurred losses or damages in connection with this Agreement, (A) the maximum aggregate liability of the Parent and Merger Sub for such losses or damages shall be limited in amount to $1 billion with their recourse to the securities issued pursuant to the Purchase Agreement or upon conversion thereof, and (B) in no event shall the Company seek to recover any money damages other than by recourse to such securities from the Parent or Merger Sub and (ii) in no event shall any officer, director, employee or Affiliate of the Parent (other than Merger Sub) (each a “Non-Recourse Party”) have any liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby. In the event that the Company or any of its Affiliates asserts in any litigation or otherwise that the provisions of this Agreement limiting the maximum aggregate liability of, and recourse of such Persons to, the Parent or Merger Sub or any of the Non-Recourse Parties as provided in the immediately preceding clause (i) is illegal, invalid or unenforceable in whole or in part, or asserting any theory of liability against Parent, Merger Sub or any of the Non-Recourse Parties with respect to the transactions contemplated by this Agreement other than payment as provided in the immediately preceding clause (i) (as limited by the provisions hereof), then the amount of the liability provided in such clause (i) shall be automatically reduced to $1,000. Notwithstanding anything to the contrary in this Section 10.12(a), in the event that any of the shares of preferred stock to be issued pursuant to the Purchase Agreement have been redeemed or any of the notes that may be issued upon conversion of such shares of preferred stock have been repaid or otherwise retired, the Company may recover from the recipient of funds pursuant to such redemption, repayment or retirement losses and damages arising from liability of Parent and/or Merger Sub (and their respective transferees) pursuant to this Agreement up the amount of the funds received thereupon in respect of the stated value of shares of preferred stock or principal amount of the notes.

(b) Specific Performance. The parties to this Agreement agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by the Company in accordance with their specific terms or were otherwise breached. It is accordingly agreed that prior to the termination of this Agreement in accordance with Article IX, the Parent and Merger Sub will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity. The parties acknowledge that the Company shall not be entitled to an injunction or injunctions to prevent breaches of this Agreement by the Parent or Merger Sub or to enforce specifically the terms and provisions of this Agreement and that the Company’s sole and exclusive remedy with respect to any such breach shall be the remedy set forth in Section 10.12(a)(i).

Section 10.13. Obligations of the Parent and of the Company. Whenever this Agreement requires a Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Corporation to cause such Subsidiary to take such action. Whenever this Agreement requires the Merger Sub to take any action, such requirements shall be deemed to include an undertaking on the part of the Parent to cause the Merger Sub to take such action.
