AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of July 25, 2008, is entered into by and among Sempra Energy, a California corporation (“Parent”), EMS Holding Corp., a Delaware corporation and a wholly owned indirect subsidiary of Parent (“Merger Sub”), and EnergySouth, Inc., a Delaware corporation (the “Company”).

WHEREAS, it is proposed that, on the terms and subject to the conditions set forth in this Agreement, Merger Sub shall merge with and into the Company (the “Merger”), and each outstanding share of common stock, par value $0.01 per share, of the Company (the “Common Stock”) shall be converted into the right to receive $61.50 in cash (the “Merger Consideration”), except for (i) shares of Common Stock held by holders who comply with the relevant provisions of the Delaware General Corporation Law (the “DGCL”) regarding the right of stockholders to dissent from the Merger and require appraisal of their shares; (ii) shares of Common Stock held in the treasury of the Company; and (iii) and shares of Common Stock owned by Parent, Merger Sub or any other wholly owned Subsidiary of Parent or the Company; and

WHEREAS, the Board of Directors of the Company has (i) approved and adopted this Agreement, (ii) determined that the Merger and the other transactions contemplated by this Agreement (the “Transactions”) are fair to and in the best interests of the Company and its stockholders, (iii) declared the advisability of this Agreement in accordance with the DGCL, and (iv) recommended that the holders of shares of Common Stock (the “Company Stockholders”) adopt this Agreement, in each case, upon the terms and subject to the conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and subject to the conditions set forth herein, the parties hereto agree as follows:

ARTICLE I

THE MERGER

Section 1.01. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, Merger Sub shall be merged with and into the Company at the Effective Time. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and the Company shall continue its existence under the Laws of the State of Delaware as a wholly owned indirect subsidiary of Parent, as the surviving corporation of the Merger (the “Surviving Corporation”).

Section 1.02. Closing. The closing of the Merger (the “Closing”) shall take place at 10:00 a.m., local time, on a date to be specified by the parties, which shall be no later than the third (3rd) Business Day after satisfaction or (to the extent permitted by applicable Law) waiver of the conditions set forth in Article VII, at the offices of Xxxxxx & Bird LLP, One Atlantic Center, 0000 Xxxx Xxxxxxxxx Xxxxxx, Xxxxxxx, XX, unless another time, date or place is agreed to

in writing by Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

Section 1.03. Effective Time. Subject to the provisions of this Agreement, at the Closing, the parties shall cause the Merger to be consummated by filing with the Secretary of State of the State of Delaware a certificate of merger (the “Certificate of Merger”), in such form as required by, and executed and acknowledged by the parties in accordance with, the relevant provisions of the DGCL, and shall make all other filings or recordings required under the DGCL in connection with the Merger. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such later time as Parent and the Company shall agree and shall specify in the Certificate of Merger (the time the Merger becomes effective being hereinafter referred to as the “Effective Time”).

ARTICLE II

EFFECTS OF THE MERGER; EXCHANGE OF CERTIFICATES

Section 2.01. Effects of the Merger. The Merger shall have the effects set forth herein and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing and subject thereto, at the Effective Time, all the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

Section 2.02. Certificate of Incorporation and Bylaws.

At the Effective Time:

(a) The Certificate of Incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein and by applicable Law, except that the name of the Surviving Corporation will be EnergySouth, Inc.

(b) The Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

Section 2.03. Directors of the Surviving Corporation. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation until the earlier of their death, resignation or removal or until their respective successors are duly elected and qualified.

Section 2.04. Officers of the Surviving Corporation. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation, each to hold office until the earlier of their death, resignation or removal or until their respective successors are duly appointed.

Section 2.05. Additional Actions. If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any further deeds, assignments or assurances in Law or any other acts are necessary or desirable to (a) vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of the Company or (b) otherwise carry out the provisions of this Agreement, the Company and its officers and directors shall be deemed to have granted to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such deeds, assignments or assurances in Law and to take all acts necessary, proper or desirable to vest, perfect or confirm title to and possession of such rights, properties or assets in the Surviving Corporation and otherwise to carry out the provisions of this Agreement, and the officers and directors of the Surviving Corporation are authorized in the name of the Company or otherwise to take any and all such action.

Section 2.06. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the Company Stockholders, or any holder of shares of capital stock of Parent or Merger Sub:

(a) Capital Stock of Merger Sub. Each issued and outstanding share of capital stock of Merger Sub shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. Each share of Common Stock that is directly owned by the Company (other than shares held in the Rabbi Trust), Parent or Merger Sub immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor. Any shares of Common Stock that are owned by a wholly owned Subsidiary of Parent (other than Merger Sub) or the Company shall remain outstanding after the Effective Time, appropriately adjusted such that such Subsidiary owns the same percentage of the Company after the Merger as it owned immediately prior to the Merger.

(c) Merger Consideration. Each share of Common Stock issued and outstanding (including shares held in the Rabbi Trust) immediately prior to the Effective Time (other than shares to be canceled or to remain outstanding in accordance with Section 2.06(b) and any Dissenting Shares) shall be converted into the right to receive an amount of cash, without interest, equal to the Merger Consideration, payable to the holder thereof. At the Effective Time, all such shares of Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of such shares of Common Stock immediately prior to the Effective Time shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration paid in consideration therefor upon surrender of such interest in accordance with Section 2.07(b). The right of any Company Stockholder to receive the Merger Consideration shall be subject to and reduced by the amount of any withholding that is required under applicable Tax Law.

(d) Dissenting Shares.

(i) Notwithstanding anything in this Agreement to the contrary, shares of Common Stock outstanding immediately prior to the Effective Time and held by a holder who is entitled to and properly demands appraisal of such shares (“Dissenting Shares”) pursuant to, and who complies in all respects with, Section 262 of the DGCL (the “Dissenters’ Provisions”) shall be entitled to payment of the fair value of such Dissenting Shares in accordance with the Dissenters’ Provisions; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to dissent under the Dissenters’ Provisions, then the right of such holder to be paid the fair value of such holder’s Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, the Merger Consideration (payable without any interest thereon).

(ii) The Company shall promptly notify Parent of any demands received by the Company for dissenter’s rights of any shares of Common Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or compromise or offer to settle or compromise, any such demand, or agree to do any of the foregoing.

Section 2.07. Exchange of Shares.

(a) Exchange Agent. Prior to the Effective Time, Parent shall appoint a bank or trust company that is reasonably satisfactory to the Company to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration for the benefit of the holders of (i) certificates representing shares of Common Stock (the “Certificates”) and (ii) shares of uncertificated Common Stock (“Uncertificated Shares”) outstanding immediately prior to the Effective Time. Prior to the Effective Time, Parent shall deposit or cause the Surviving Corporation to deposit with the Exchange Agent, for the benefit of the holders of the Certificates and the Uncertificated Shares, cash in an amount sufficient to pay the aggregate Merger Consideration required to be paid pursuant to Section 2.06(c). Any funds deposited with the Exchange Agent pursuant to this Section 2.07(a) shall hereinafter be referred to as the “Exchange Fund.” The Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly (and in any event within five (5) Business Days) after the Effective Time, Parent shall cause the Exchange Agent to mail to each Company Stockholder of record whose shares of Common Stock were converted into the right to receive the Merger Consideration (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Exchange Agent and which shall be in customary form and contain customary provisions) and (ii) instructions to effect the surrender of the Certificates or transfer of the Uncertificated Shares in exchange for the Merger Consideration. Each Company Stockholder of record shall, upon surrender or transfer to the Exchange Agent of the Common Stock, together with such duly executed letter of transmittal and such other documents as may reasonably be required by the Exchange Agent, be entitled to receive in exchange therefor the amount of cash to which such holder is entitled pursuant to

Section 2.06(c). In the event of a transfer of ownership of Common Stock that is not registered in the transfer records of the Company, payment of the Merger Consideration in accordance with this Section 2.07(b) may be made to a Person other than the Person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or establish to the reasonable satisfaction of Parent that such Taxes have been paid or are not applicable. Until surrendered as contemplated by this Section 2.07(b), each Certificate or Uncertificated Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration upon surrender. No interest shall be paid or will accrue on any payment to holders of Certificates or Uncertificated Shares pursuant to the provisions of this Article II.

(c) No Further Ownership Rights in Common Stock. The Merger Consideration paid upon the surrender of shares of Common Stock in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Common Stock. At the close of business on the day on which the Effective Time occurs, the share transfer books of the Company shall be closed, and there shall be no further registration of transfers on the share transfer books of the Surviving Corporation of the shares of Common Stock outstanding immediately prior to the Effective Time.

(d) Termination of the Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the Company Stockholders on the date that is one (1) year after the Effective Time shall be delivered to Parent, upon demand, and any Company Stockholders who have not theretofore complied with this Article II shall thereafter look only to Parent for, and Parent shall remain liable for, payment of their claim for the Merger Consideration in accordance with this Article II.

(e) No Liability. None of Parent, Merger Sub, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any Person in respect of any funds from the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Investment of Exchange Fund. The Exchange Agent shall invest the cash in the Exchange Fund as directed by Parent; provided that such investments shall be in obligations of, or guaranteed by, the United States or of any agency thereof and backed by the full faith and credit of the United States, in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in deposit accounts, certificates of deposit or banker’s acceptances of, repurchase or reverse repurchase agreements with, or Eurodollar time deposits purchased from, commercial banks with capital, surplus and undivided profits aggregating in excess of $500 million (based on the most recent financial statements of such bank that are then publicly available at the SEC or otherwise). Any interest and other income resulting from such investments shall be paid to and be income of Parent. If for any reason (including losses), the cash in the Exchange Fund shall be insufficient to fully satisfy all of the payment obligations to be made in cash by the Exchange Agent hereunder, Parent shall, or shall cause the Surviving Corporation to, promptly deposit cash into the Exchange Fund in the amount required to fully satisfy such cash payment obligations.

(g) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person (who shall be the record owner of such Certificate) claiming such Certificate to be lost, stolen or destroyed, and, if required by the Exchange Agent or Parent, the posting by such Person of a bond in customary amount and upon such terms as may be required as indemnity against any claim that may be made against them or the Surviving Corporation with respect to such Certificate, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration pursuant to this Article II.

(h) Withholding Rights. Each of Parent, the Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it reasonably determines that 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”), or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by Parent, the Surviving Corporation or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Company Stockholder in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Exchange Agent.

Section 2.08. Company Stock-Based Awards.

(a) As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Company Stock Option outstanding immediately prior to the Effective Time, whether or not vested or exercisable, shall be cancelled and the holder thereof shall be entitled to receive at the Effective Time from the Surviving Corporation an amount of cash, without interest, equal to the product of (i) the total number of shares subject to such Company Stock Option, multiplied by (ii) the excess, if any, of the Merger Consideration over the exercise price per share of such Company Stock Option (with the aggregate amount of such payment to the holder to be rounded to the nearest cent), less the amount of any withholding required under applicable Tax Law.

(b) As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each outstanding Performance Share Award and Performance-Based Restricted Stock Unit Award outstanding immediately prior to the Effective Time shall be cancelled and the holder thereof shall be entitled to receive at the Effective Time from the Surviving Corporation an amount of cash, without interest, equal to the product of (i) the target number of shares or units underlying such award, multiplied by (ii) the Merger Consideration (with the aggregate amount of such payment to the holder to be rounded to the nearest cent), less the amount of any withholding required under applicable Tax Law.

(c) As of the Effective Time, by virtue of the Merger and without any action on the part of the participants therein, the phantom stock units (“Phantom Stock Units”) credited to each participant’s account under the Second Amended and Restated EnergySouth, Inc. Non-Employee Directors Deferred Fee Plan and the 2005 Non-Employee Directors Deferred Fee Plan (“Deferred Fee Plans”) shall be converted into a dollar amount equal to the product of (i) the number of Phantom Stock Units credited to such participant’s account, multiplied by (ii) the

Merger Consideration (with such amount to be rounded to the nearest cent). As of the Effective Time, such dollar amount shall be credited to such participant’s cash account under the applicable Deferred Fee Plan, and the Phantom Stock Units shall be debited from such participant’s plan account. As of the Effective Time and thereafter, such participant’s account shall be credited with interest when and as provided in the applicable Deferred Fee Plan and distributable in cash in accordance with the participant’s distribution election and the terms and conditions of the Deferred Fee Plans. Prior to the Effective Time, the Company shall amend the Deferred Fee Plans to provide that, as of the Effective Time and thereafter, no further Phantom Stock Units shall be credited to the accounts of participants and the accounts of participants shall be distributable only in the form of cash.

(d) Prior to the Effective Time, the Board of Directors of the Company (or the appropriate committee thereof) shall take or cause to be taken all actions necessary to effectuate this Section 2.08 to the extent such treatment is not expressly provided for by the terms of the applicable Stock Plans and related award agreements, Contracts or participant election forms, including, without limitation, the adoption of any necessary amendments to the Stock Plans. Prior to the Effective Time and as soon as administratively practicable, the Company shall use commercially reasonable efforts to obtain from each holder of Company Stock Options granted under the Amended and Restated Stock Option Plan of EnergySouth, Inc. and the 2003 Stock Option Plan of EnergySouth, Inc. a written consent and release (in a form reasonably acceptable to Parent) providing for the treatment of such Company Stock Options as provided under Section 2.08(a) hereof, which Section 2.08(a) will govern regardless of whether a particular holder of a Company Stock Option delivers such a consent.

(e) Notwithstanding anything in this Agreement to the contrary, if the Effective Time occurs prior to November 15, 2008, immediately prior to the Effective Time, the Company shall pay any amounts due to each employee then actively employed by the Company or a Company Subsidiary under an outstanding award granted under the Company’s Executive Incentive Compensation Plan or Employee Incentive Compensation Plan with respect to the full fiscal year ending on September 30, 2008. The amount of each such payment shall be reasonably consistent with the intent of the Company’s Executive Incentive Compensation Plan or Employee Incentive Compensation Plan, as determined in the exercise of reasonable good faith discretion by the Compensation Committee of the Board of Directors with regard to the Executive Incentive Compensation Plan and by the President and Chief Executive Officer of the Company with regard to the Employee Incentive Compensation Plan; provided, that the aggregate amount of such payments under both such Plans shall not exceed $4,800,000. In the event the Effective Time occurs on or after November 15, 2008, immediately prior to the Effective Time, the Company shall pay to each employee any amounts due such employee under the terms and conditions of such an award and the Executive Incentive Compensation Plan or Employee Incentive Compensation Plan for the full fiscal year ending September 30, 2008; provided, that the aggregate amount of such payments under both such Plans shall not exceed $4,800,000. For the avoidance of doubt, the $4,800,000 cap on payments described above under this Section 2.08(e) shall be exclusive of the bonus pool funding the Team Performance Awards, as defined in the Employment Agreements, effective April 2, 2007, between EnergySouth Midstream, Inc. and Xxx X. Xxxxx, W. Xxxx Xxxxx and Xxxx X. Xxxxxxxxx, which Team Performance Awards shall be paid in accordance with such Employment Agreements. Not less than five (5) Business Days prior to the determination of the amounts of such payments by the

Compensation Committee of the Board of Directors of the Company (in the case of the Executive Incentive Compensation Plan), or the Chief Executive Officer of the Company (in the case of the Employee Incentive Compensation Plan), as applicable, the Company shall provide to Parent a schedule setting forth the employees to whom the payments described in this Section 2.08(e) are to be made, and the amount of each such payment. For purposes of any employment agreement entered into between the Company or a Company Subsidiary and such an employee, such payment shall be deemed full payment of such employee’s annual incentive award pursuant to the terms of such employee’s employment agreement.

Section 2.09. Adjustments to Prevent Dilution. In the event that the Company changes the number of shares of Common Stock or securities convertible or exchangeable into or exercisable for shares of 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

Each disclosure set forth in the Company Disclosure Schedule is identified by reference to, or has been grouped under a heading referring to, a specific individual section of this Agreement, and disclosure made pursuant to any section of the Company Disclosure Schedule shall be deemed to be disclosed on each of the other sections of the Company Disclosure Schedule to the extent the applicability of the disclosure to such other section is reasonably apparent, except in the case of the disclosure applicable to qualifying the representation set forth on Section 3.08(c) which shall be set forth only on Section 3.08(c) of the Company Disclosure Schedule.

Section 3.01. Organization and Qualification; Subsidiaries.

(a) The Company and each Subsidiary of the Company (collectively, the “Company Subsidiaries”) is a corporation, limited liability company, general partnership or limited partnership duly formed, validly existing and in good standing (to the extent applicable) under the Laws of the jurisdiction of its formation. The Company and each Company Subsidiary has the requisite corporate, limited liability company or partnership power and authority to own, lease, sublease, use and operate its properties and assets and to carry on its business as it is now being conducted, except as has not had and would not reasonably be expected to have a Material

The Company and Parent shall, and Parent shall cause Merger Sub to, to the extent permitted by Law, promptly provide the other with copies of all filings made by such party with any Governmental Authority in connection with this Agreement and the Transactions, other than the portions of such filings that include confidential or proprietary information not directly related to the Transactions.

Nothing contained in this Agreement (including, without limitation, this Section 5.01) is intended to give Parent or Merger Sub, directly or indirectly, the right to control or direct the Company’s or any of the Company Subsidiaries’ operations prior to the Effective Time, and nothing contained in this Agreement is intended to give the Company, directly or indirectly, the right to control or direct Parent’s or any of its Subsidiaries’ operations. Prior to the Effective Time, each of Parent, Merger Sub and the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

Section 5.02. No Solicitation.

(a) Except as set forth in this Section 5.02, until the earlier of the Effective Time or the termination of this Agreement pursuant to Article VIII, the Company shall not, and shall not authorize or permit the Company Subsidiaries or any of their respective directors, officers, employees, advisors, agents, representatives or controlled Affiliates (collectively, “Representatives”) to, directly or indirectly, (i) solicit, initiate, knowingly encourage or knowingly facilitate any Takeover Proposal or the making thereof, (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information in connection with, or otherwise cooperate in any way with, any Takeover Proposal or (iii) waive, terminate, modify or fail to enforce any provision of any contractual “standstill” or similar obligation of any Person other than Parent. The Company shall, and shall cause the Company Subsidiaries to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any Takeover Proposal, terminate any and all Persons’ (other than Parent and its Affiliates) access to the Company’s electronic data room and request the prompt return or destruction of all confidential information previously furnished or provided to any such Person in connection with any applicable confidentiality agreement. Notwithstanding anything in this Agreement, in response to a written

Takeover Proposal that the Board of Directors of the Company or any committee thereof reasonably determines in good faith is bona fide and (after consultation with outside counsel and a financial advisor of nationally recognized reputation) is, or is reasonably likely to result in, a Superior Proposal, and which Takeover Proposal was made after the date hereof and was not the result of a material breach by the Company of this Section 5.02(a), the Company may (A) furnish information with respect to the Company and the Company Subsidiaries to the Person making such Takeover Proposal (and its Representatives) pursuant to a confidentiality agreement containing confidentiality provisions, not less restrictive to such Person than the provisions of the Confidentiality Agreement are to Parent; provided that all such information has previously been provided to Parent or is provided to Parent prior to or substantially concurrent with the time it is provided to such Person, and (B) participate in discussions or negotiations with the Person making such Takeover Proposal (and its Representatives) regarding such Takeover Proposal, if and only to the extent that in connection with the foregoing clauses (A) and (B), the Board of Directors of the Company concludes in good faith (after consultation with its outside counsel and a financial advisor of nationally recognized reputation) that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law.

The term “Takeover Proposal” means any inquiry, proposal or offer from any Person (other than Parent and its Affiliates) relating to, or that could reasonably be expected to lead to, any direct or indirect acquisition or purchase, in one transaction or a series of transactions, of assets (including equity securities of any Company Subsidiary) or businesses that constitute 20% or more of the revenues, net income or assets of the Company and the Company Subsidiaries, taken as a whole, or 20% or more of any class of equity securities of the Company, any tender offer or exchange offer that if consummated would result in any Person beneficially owning 20% or more of any class of equity securities of the Company, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, share exchange or similar transaction involving the Company or the Company Subsidiaries pursuant to which any Person or the equityholders of any Person would own 20% or more of any class of equity securities of the Company or of any resulting parent company of the Company, in each case other than the Transactions. For purposes of this definition, a Person shall also mean any group (as defined in Rule 13d-5 under the Exchange Act) of Persons (other than Parent and its Affiliates).

The term “Superior Proposal” means any bona fide Takeover Proposal (with all percentages in the definition of Takeover Proposal changed to 50%) made in writing and not the result of a violation of Section 5.02(a) that the Board of Directors of the Company reasonably determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be: (i) more favorable to the Company Stockholders from a financial point of view than the Transactions, and (ii) reasonably likely to be completed on the terms proposed, taking into account all financial, legal, regulatory and other aspects of such proposal, in each case of clauses (i) and (ii), after taking into account any written proposal by Parent in response to such Takeover Proposal or any written proposal by Parent to amend the terms of the Transactions.

(b) Except as set forth in this Section 5.02, until the earlier of the time that the Stockholder Approval is received or the termination of this Agreement pursuant to Article VIII, neither the Board of Directors of the Company nor any committee thereof shall (i) (A) withdraw, modify or qualify the Company Recommendation in any manner adverse to Parent, (B) take any

other action or make any public statement in connection with the Company Recommendation, the Merger or the Company Stockholders’ Meeting that is inconsistent with the Company Recommendation, or fail to make the Company Recommendation in the Proxy Statement or (C) adopt or recommend, or propose publicly to adopt or recommend, any Takeover Proposal (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”), or (ii) adopt or recommend, or publicly propose to adopt or recommend, or approve the Company’s or the Company Subsidiaries’ execution or entry into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar Contract constituting or related to, or that is intended to or could reasonably be expected to lead to, any Takeover Proposal (other than a confidentiality agreement referred to in Section 5.02(a)) (an “Acquisition Agreement”).

(c) Notwithstanding anything in this Agreement to the contrary, at any time prior to the time that the Stockholder Approval is received and subject to Section 5.02(e), the Board of Directors of the Company may make a Company Adverse Recommendation Change: (i) in response to a material development or change in material circumstances occurring or arising after the date hereof, the existence and material consequences of which were not known to the Company’s Board of Directors as of or prior to the date hereof (and not relating to any Takeover Proposal), if the Board of Directors of the Company concludes in good faith, after consultation with its outside counsel, that the failure of the Board of Directors to make a Company Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable Law or (ii) in response to a Takeover Proposal, if the Board of Directors of the Company concludes that such Takeover Proposal constitutes a Superior Proposal, and such Takeover Proposal was made after the date hereof and was not the result of a material breach of this Section 5.02. If the Board of Directors of the Company makes a Company Adverse Recommendation Change pursuant to Section 5.02(c)(ii), the Company may terminate this Agreement pursuant to Section 8.01(f), and enter into an Acquisition Agreement, if the Board of Directors of the Company has concluded in good faith, after consultation with its outside counsel, that, in light of such Superior Proposal, the failure of the Board of Directors to terminate this Agreement would be inconsistent with its fiduciary duties under applicable Law; provided, however, that the Board of Directors of the Company (including any committee thereof) may not effect a Company Adverse Recommendation Change as contemplated in Section 5.02(c)(ii) and/or terminate this Agreement pursuant to Section 8.01(f) unless:

(A) the Company shall have provided prior written notice to Parent and Merger Sub, at least four (4) Business Days in advance (the “Notice Period”), of its intention to effect a Company Adverse Recommendation Change in response to a Superior Proposal and/or to terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal, which notice shall specify the material terms and conditions of any such Superior Proposal, and contemporaneously with providing such notice shall have provided a copy of the relevant proposed transaction agreements with the party making such Superior Proposal and any other materials submitted therewith; and

(B) prior to effecting such Company Adverse Recommendation Change in response to a Superior Proposal and/or terminating this Agreement to enter into a definitive agreement with respect to such Superior Proposal, if requested by Parent the Company

shall, and shall cause its legal and financial advisors to, during the Notice Period, negotiate with Parent and Merger Sub in good faith (to the extent Parent and Merger Sub desire to negotiate) to make such adjustments to the terms and conditions of this Agreement so that such Takeover Proposal ceases to constitute a Superior Proposal.

In the event that during the Notice Period any revisions are made to the Superior Proposal to which the proviso in this Section 5.02(c) applies and the Board of Directors of the Company in its good faith judgment determines such revisions are material (it being agreed that any change in the purchase price in such Superior Proposal shall be deemed a material revision), the Company shall be required to deliver a new written notice to Parent and Merger Sub and to comply with the requirements of this Section 5.02(c) with respect to such new written notice except that the Notice Period shall be reduced to two (2) Business Days.

(d) In addition to the obligations of the Company set forth in subsections (a) through (c) of this Section 5.02, the Company shall (i) promptly (and in any event within 24 hours of learning of the relevant information) advise Parent orally and in writing of the receipt of any Takeover Proposal, the material terms and conditions of any such Takeover Proposal (including any changes thereto) and the identity of the Person making any such Takeover Proposal, (ii) keep Parent informed in all material respects of the status and details (including any change to the material terms thereof) of any Takeover Proposal and (iii) publicly reaffirm the Company Recommendation within ten (10) Business Days of receipt of a written request by Parent to provide such reaffirmation, unless a Company Adverse Recommendation Change is permitted by Section 5.02(c).

(e) Nothing contained in this Section 5.02 shall prohibit the Company or the Board of Directors of the Company from at any time taking and disclosing to the Company Stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act or making a statement required under Rule 14d-9 under the Exchange Act or other applicable Law; provided, however, that in no event shall the Company or the Board of Directors of the Company or any committee thereof take, or agree or resolve to take, any action prohibited by Section 5.02(b).

If any of the information or material furnished pursuant to this Section 6.02(a) includes materials or information subject to the attorney-client privilege, work product doctrine or any other applicable privilege concerning pending or threatened Action, each party understands and agrees that the parties have a commonality of interest with respect to such matters and it is the desire, intention and mutual understanding of the parties that the sharing of such material or information is not intended to, and shall not, waive or diminish the confidentiality of such material or information or its continued protection under the attorney-client privilege, work product doctrine or other applicable privilege. All such information provided by the Company that is entitled to protection under the attorney-client privilege, work product doctrine or other applicable privilege shall remain entitled to such protection under these privileges, this Agreement, and under the joint defense doctrine. Subject in all respects to the terms of this Section 6.02(a), promptly after receipt thereof, the Company shall deliver to Parent copies of any written reports to the Company’s risk management committee or similar body, pursuant to the Company’s existing risk management policies (including the Company Trading Policies), in connection with any breaches of, or exceptions from, the Company’s existing risk management policies (including the Company Trading Policies).

The Confidentiality Agreement shall survive any termination of this Agreement in accordance with its terms.

Section 6.03. Further Action; Efforts.

(a) Subject to the terms and conditions of this Agreement, each party shall (and shall cause its Subsidiaries to) use its commercially 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

consummate the Merger and the other Transactions, including preparing and filing as soon as reasonably practicable all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents necessary to consummate the Merger and the other Transactions. In furtherance and not in limitation of the foregoing, each party agrees (i) to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the Transactions as soon as reasonably practicable after the date hereof, (ii) to supply as promptly as reasonably practicable any additional information and documentary material that may be requested pursuant to the HSR Act and (iii) use commercially reasonable efforts to take or cause to be taken all other actions necessary, proper or advisable to cause the expiration or termination of the applicable waiting periods with respect to the Merger under the HSR Act.

(c) In addition to and not in limitation of the covenants of the parties contained in Sections 6.03(a) and (b), each party hereto shall use its best efforts (in each case to the extent permitted under applicable Law) to resolve such objections, if any, as may be asserted with respect to the Transactions under any Antitrust Law, including agreeing to take or cause its Subsidiaries to take any action or agree to take any action or consent to the taking of any action not inconsistent with this Section 6.03(c). Notwithstanding the foregoing, nothing in this Section 6.03 shall require any party hereto to take any action which (i) requires any party hereto to sell, hold separate or otherwise dispose of any business or assets, or conduct its (or its Subsidiaries’) business in any specified manner, (ii) is reasonably likely to have a material adverse effect on the condition (financial or otherwise), business, assets, liabilities or results of operations of either Parent (or any of its Subsidiaries) or the Company, taken individually or in the aggregate, or (iii) is not conditioned on the consummation of the Merger.

(d) In the event that any administrative or judicial Action is instituted (or threatened to be instituted) by a Governmental Authority or private party challenging the Merger or the other Transactions, each of Parent, Merger Sub and the Company shall cooperate with each other and use its commercially reasonable efforts (in each case to the extent practicable and

Section 6.04. Indemnification, Exculpation and Insurance.

(a) As of the Effective Time, Parent shall, and shall cause the Surviving Corporation to, indemnify and hold harmless the current and former directors and officers of the Company and the Company Subsidiaries in respect of acts or omissions occurring at or prior to the Effective Time to the fullest extent permitted by Law or as provided in the Company Certificate, the Company Bylaws, the organizational documents of any Company Subsidiary or any written indemnification Contract between such directors or officers and the Company (in each case, as in effect on the date hereof). Such obligations shall survive the Merger and shall continue in full force and effect in accordance with their terms. From the Effective Time through the sixth (6^th) anniversary of the date on which the Effective Time occurs, the certificate of incorporation and bylaws of the Surviving Corporation shall contain, and Parent shall cause the certificate of incorporation and bylaws of the Surviving Corporation to contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of the Company and the Company Subsidiaries for acts or omissions occurring at or prior to the Effective Time than are presently set forth in the Company Certificate and Company Bylaws, and such provisions shall not be amended, repealed, or otherwise modified in any manner that could adversely affect the rights thereunder of any Person benefited by such provisions. Parent hereby unconditionally guarantees the obligations of the Surviving Corporation under this Section 6.04.

(b) In the event that the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and other assets to any Person, then, and in each such case, Parent shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation shall expressly assume the obligations set forth in this Section 6.04.

(c) The Company shall use commercially reasonable efforts to purchase, prior to the Effective Time, and if the Company does not so purchase, Parent shall or shall cause the Surviving Corporation to purchase promptly after the Effective Time a six-year “tail” prepaid policy on the Company’s directors’ and officers’ liability insurance policy covering each person currently covered by the Company’s directors’ and officers’ liability insurance policy, on terms with respect to such coverage and amounts no less favorable than those of such policy in effect on the date hereof. Following the Effective Time, Parent shall or shall cause the Surviving Corporation to maintain such “tail” policy in full force and effect and to continue to honor its obligations thereunder. If the Company, Parent and the Surviving Corporation for any reason fail to obtain such “tail” policy as of or promptly after, as applicable, the Effective Time, Parent shall, or shall cause the Surviving Corporation to, maintain (directly or indirectly through the Company’s existing insurance programs) in effect the Company’s current directors’ and officers’ liability insurance in respect of acts or omissions occurring at or prior to the Effective Time, covering each person currently covered by the Company’s directors’ and officers’ liability

insurance policy (a complete and accurate copy of which has been previously delivered to Parent), on terms with respect to such coverage and amounts no less favorable than those of such policy in effect on the date hereof; provided, however, that Parent may (i) substitute policies of Parent containing terms with respect to coverage (including with respect to deductibles and exclusions) and amounts no less favorable to such directors and officers or (ii) request that the Company obtain such extended reporting period coverage under its existing insurance programs, to be effective as of the Effective Time, or, if such insurance is unavailable, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, purchase the best available coverage (including with respect to deductibles and exclusions) for such six-year period from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to the Company’s existing directors’ and officers’ liability insurance with terms, conditions, retentions and with levels of coverage at least as favorable as provided in the Company’s existing policies as of the date of this Agreement. Notwithstanding anything in the foregoing, in no event shall Parent or the Surviving Corporation be required to expend for such policies an annual premium amount in excess of 300% of the annual premiums currently paid by the Company for such insurance; and provided further, that if the annual premiums of such insurance coverage exceed such amount, the Surviving Corporation shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(d) The provisions of this Section 6.04 (i) are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by Contract or otherwise.

Section 6.05. Fees and Expenses.

(a) Except as otherwise provided in this Section 6.05, all fees and expenses incurred in connection with this Agreement, the Merger and the other Transactions shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated.

(b) In the event that this Agreement is terminated by Parent pursuant to Section 8.01(e), then the Company shall pay Parent the Termination Fee by wire transfer of same-day funds on the second (2^nd) Business Day following the date of termination of this Agreement.

(c) In the event that this Agreement is terminated by the Company pursuant to Section 8.01(f), then the Company shall pay Parent the Termination Fee by wire transfer of same-day funds concurrently with such termination.

(d) In the event that this Agreement is terminated:

(i) by Parent pursuant to Section 8.01(c) and, prior to the breach giving rise to such right of termination, a Takeover Proposal has been publicly announced or shall have otherwise become publicly known;

(ii) by the Company or Parent pursuant to Section 8.01(b)(ii) and, prior to such termination, a Takeover Proposal has been publicly announced or shall have otherwise become publicly known; or

(iii) by the Company or Parent pursuant to Section 8.01(b)(iii) and prior to the Company Stockholders’ Meeting, a Takeover Proposal has been publicly announced or shall have otherwise become publicly known; and

within nine (9) months after such termination, the Company enters into a definitive Contract to consummate, or consummates, the transactions contemplated by any Takeover Proposal (regardless of whether such Takeover Proposal is made before or after termination of this Agreement), then the Company shall pay Parent the Termination Fee by wire transfer of same-day funds on the second (2^nd) Business Day following the earlier of the date the Company enters into such Contract or consummates such Takeover Proposal. For purposes of this Section 6.05(d), all references (whether in words or numerals) to “twenty percent (20%)” in the definition of Takeover Proposal shall be deemed to refer to “more than fifty percent (50%).”

(e) The Company and Parent acknowledge and agree that the agreements contained in Section 6.05 are an integral part of the Transactions, and that, without these agreements, Parent would not enter into this Agreement. Accordingly, if the Company fails promptly to pay any amount due pursuant to Section 6.05, and, in order to obtain such payment, Parent commences an Action that results in a judgment against the Company for the Termination Fee, the Company shall pay Parent its costs and expenses (including attorneys’ fees and expenses) in connection with such Action, together with interest on the amount of the Termination Fee and/or expenses, as the case may be, from the date such payment was required to be made until the date of payment, at the prime rate of Regions Bank, in effect on the date such payment was required to be made.

Section 6.06. Public Announcements. Except with respect to any Company Adverse Recommendation Change made in accordance with the terms of this Agreement, Parent and the Company shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other public statements with respect to the Transactions, including the Merger, and shall not issue any such press release or make any such public statement prior to such consultation, except as such party may reasonably conclude may be required by applicable Law, by court process or by obligations pursuant to any listing agreement with any national securities exchange.

Section 6.07. Stockholder Litigation. The Company shall give Parent prompt written notice of, and the opportunity to participate in, subject to a customary joint defense agreement, but not control, the defense or settlement of, any stockholder litigation against the Company and/or its directors relating to the Transactions, and no such settlement shall be agreed to without Parent’s prior written consent, which consent shall not be unreasonably withheld or delayed.

(c) Parent shall cause the Surviving Corporation to recognize the service of each Continuing Employee as if such service had been performed with Parent with respect to any plans or programs in which Continuing Employees are eligible to participate after the Effective Time (i) for purposes of determining eligibility to participate and vesting (but not benefit accrual) under any defined benefit pension plan, if any, (ii) for purposes of determining eligibility for, and the amount of, vacation and any other paid time-off plan or policy, (iii) for purposes of determining eligibility and participation under any defined contribution plan or health or welfare plan (including any post-employment health or post-employment welfare plan), (iv) for purposes of eligibility for any company matching contributions, and (v) unless covered under another arrangement with or of the Company, for the purpose of determining eligibility for, and the amount of, any severance payable under any severance plan of general application, except, in each case, to the extent such treatment would result in duplicative benefits.

(d) With respect to any welfare plan maintained by Parent in which Continuing Employees are eligible to participate after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees to the extent such conditions and exclusions were satisfied or did not apply to such employees under the welfare plans maintained by the Company prior to the Effective Time and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any analogous deductible or out-of-pocket requirements applicable under any such plan, to the extent credited under the welfare plans maintained by the Company prior to the Effective Time.

(e) The provisions of this Section 6.08 are for the sole benefit of the parties to this Agreement and nothing herein, expressed or implied, is intended or shall be construed to (i) constitute an amendment to any of the compensation and Benefits Plans maintained for or provided to Continuing Employees prior to or following the Effective Time, or (ii) confer upon or give to any Person (including for the avoidance of doubt any Employees or current or former

Section 9.10. Specific Enforcement; Consent to Jurisdiction. The parties agree that irreparable damage would occur in the event any provision of this Agreement were not performed in accordance with the terms hereof or were otherwise breached and that money damages would not be a sufficient remedy for any breach of this Agreement, and accordingly, the parties hereto shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

submits, for itself and its property, to the exclusive jurisdiction of the Delaware Court of Chancery or, in the event (but only in the event) such court does not have subject matter jurisdiction, any other court of the State of Delaware or the United States District Court for the District of Delaware, in any Action arising out of or relating to this Agreement or the Transactions.
