PRELIMINARY PROXY STATEMENT — SUBJECT TO COMPLETION, DATED AUGUST 8, 2008

2828 Dauphin Street

Mobile, Alabama 36606

PROPOSED MERGER — YOUR VOTE IS VERY IMPORTANT

To the Stockholders of EnergySouth, Inc.:

You are cordially invited to attend a special meeting of the stockholders of EnergySouth, Inc. to be held on [ • ], 2008, at 10:00 a.m., local time, at the Auditorium at the principal office of the company, 2828 Dauphin Street, Mobile, Alabama 36606.

At the special meeting, you will be asked to consider and vote upon an Agreement and Plan of Merger, dated July 25, 2008, which we refer to as the merger agreement, by and among EnergySouth, Sempra Energy and EMS Holding Corp., a wholly-owned indirect subsidiary of Sempra Energy. Pursuant to the merger agreement, EMS Holding Corp. will be merged with and into EnergySouth, with EnergySouth surviving as a wholly-owned, indirect subsidiary of Sempra Energy.

If the merger is completed, you will be entitled to receive $61.50 in cash, without interest and less any applicable withholding tax, for each share of EnergySouth common stock that you own, unless you have sought and properly perfected your appraisal rights under the Delaware General Corporation Law (under which we are incorporated). The $61.50 in cash for each share of EnergySouth common stock you own represents a 22.6% premium over the last reported sale price of EnergySouth’s common stock before the July 28, 2008 public announcement of the merger and a 21.8% premium over the average reported last sale price of EnergySouth’s common stock over the 90 days prior to July 23, 2008. After the merger, you will no longer have an equity interest in EnergySouth.

Your vote is very important, regardless of the number of shares you own. We cannot complete the merger unless the holders of a majority of all outstanding shares of EnergySouth common stock entitled to vote on the matter vote to adopt the merger agreement and approve the merger. Therefore, if you do not return your proxy card, submit your proxy via the Internet or telephone or vote in person at the special meeting, it will have the same effect as if you had voted “AGAINST” the adoption of the merger agreement and the approval of the merger. Our board of directors has unanimously approved the merger agreement and determined that the merger agreement and the merger are advisable and in the best interests of EnergySouth and our stockholders. Our board of directors unanimously recommends that you vote “FOR” the adoption of the merger agreement and approval of the merger. In arriving at its recommendation, the board of directors carefully considered a number of factors described in the accompanying proxy statement.

The accompanying proxy statement provides you with detailed information regarding the special meeting and the proposed merger and includes the merger agreement as Annex A. We encourage you to read the proxy statement and merger agreement carefully.

Sincerely,

C.S. “Dean” Liollio
President and Chief Executive Officer

PROXY STATEMENT FOR

SPECIAL MEETING OF STOCKHOLDERS

QUESTIONS AND ANSWERS ABOUT THE MERGER

The following questions and answers are intended to briefly address some questions regarding the merger, the special meeting and other matters to be considered by EnergySouth’s stockholders at the special meeting. These questions and answers may not address all questions that may be important to you as a stockholder. Please refer to the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents referred to or incorporated by reference in this proxy statement.

Except as otherwise specifically noted in this proxy statement, “we,” “our,” “us” and similar words refer to EnergySouth, Inc. In addition we refer to EnergySouth, Inc. as “EnergySouth” or the “Company,” to Sempra Energy as “Sempra Energy” and to EMS Holding Corp. as “Merger Sub.”


Q1:		On what am I being asked to vote?

A1:		You are being asked to vote on a proposal to adopt the Agreement and Plan of Merger, dated as of July 25, 2008, by and among EnergySouth, Sempra Energy and Merger Sub, which we refer to as the merger agreement, and to approve the merger contemplated therein. Pursuant to the merger agreement:

		• Merger Sub will merge into EnergySouth, with EnergySouth continuing as the surviving corporation; and

		• each outstanding share of our common stock will be cancelled and converted into the right to receive $61.50 in cash, without interest and less any applicable withholding tax, except for shares held by stockholders who properly perfect their appraisal rights in accordance with Delaware law and shares held by EnergySouth, Sempra Energy or Merger Sub or their respective subsidiaries.

		You may also be asked to vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies in support of the proposal to adopt the merger agreement and approve the merger if there are not sufficient votes at the special meeting to do so.

Q2:		What will be the effect of the merger?

A2:		After the merger, you will no longer own any of our common stock. All of the capital stock of EnergySouth following completion of the merger will be owned by Sempra Energy, and we will operate as a wholly-owned, indirect subsidiary of Sempra Energy.

Q3:		If the merger is completed, what will I receive for the shares of EnergySouth common stock I hold?

A3:		If the merger is completed, each share of EnergySouth common stock owned by you at the effective time of the merger will be automatically cancelled and converted into the right to receive $61.50 in cash, without interest and less any applicable withholding tax; except that, alternatively, if you perfect your appraisal rights in accordance with Delaware law, your shares will be subject to appraisal by a court in accordance with Delaware law.

Q4:		If the merger is completed, what will happen to outstanding options to acquire EnergySouth common stock?

A4:		Each outstanding and unexercised option to acquire EnergySouth common stock (whether vested or unvested) at the effective time of the merger will be cancelled in exchange for a cash payment, without interest, equal to the product of (1) the number of shares of EnergySouth common stock subject to such option multiplied by (2) the amount by which $61.50 exceeds the option exercise price per share of common stock subject to such option, less any required withholding taxes.


Q5:		How does EnergySouth’s board of directors recommend that I vote?

A5:		Our board of directors has unanimously approved the merger agreement and declared the merger agreement and the merger advisable and in the best interests of EnergySouth stockholders. Our board of directors unanimously recommends that you vote “FOR” adoption of the merger agreement and approval of the merger and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Q6:		When and where is the special meeting?

A6:		The special meeting is scheduled to take place on [ • ] , 2008, at 10:00 a.m., local time, at the Auditorium at the principal office of the Company, 2828 Dauphin Street, Mobile, Alabama.

Q7:		Who can vote at the special meeting?

A7:		Only stockholders of record as of the close of business on [ • ], 2008, are entitled to receive notice of the special meeting and to vote the shares of our common stock that they hold at that record date at the special meeting, or at any adjournments or postponements of the special meeting.

Q8:		What vote is required to adopt the merger agreement and approve the merger and approve an adjournment of the special meeting, if necessary? How do EnergySouth’s directors and executive officers intend to vote?

A8:		Adoption of the merger agreement and approval of the merger requires the affirmative vote of the holders of a majority of the outstanding shares of our common stock entitled to vote on the merger. Adjournment of the special meeting, if necessary, to solicit additional proxies requires the affirmative vote of the holders of a majority of the shares of our common stock present in person or represented by proxy and entitled to vote at the special meeting.

		All of our directors and executive officers, who beneficially own a total of 990,151 shares that represent approximately 11.9% of our issued and outstanding common stock, have indicated to us that they intend to vote in favor of the adoption of the merger agreement and approval of the merger and the adjournment of the special meeting, if necessary.

Q9:		May I vote in person?

A9:		Yes. If your shares are registered in your name, rather than held in “street name” through a broker or bank, you may attend the special meeting and vote your shares in person, rather than signing and returning your proxy card or submitting your proxy via the Internet or telephone. If your shares are held in “street name,” you must get a proxy from your broker or bank in order to attend the special meeting and vote.

Q10:		If my shares are held in “street name” by my broker or bank, will my broker or bank vote my shares for me?

A10:		Your broker or bank will not be able to vote your shares on the proposal to adopt the merger agreement and approve the merger without instructions from you. You should instruct your broker or bank to vote your shares by following the procedure provided by your broker or bank. Without instructions, your shares will not be voted, which will have the same effect as if you voted “AGAINST” adoption of the merger agreement and approval of the merger. Your broker or bank will be able to vote your shares in its discretion on the proposal to adjourn the special meeting if necessary, even if you do not provide instructions to your broker or bank on how to vote.

Q11:		Can I change my vote or revoke my proxy after I have mailed my signed proxy card?

A11:		Yes. You can change your vote at any time before your proxy is voted at the special meeting. You can do this in one of three ways:

		• First, you can send a written notice to the Secretary of EnergySouth stating that you would like to revoke your proxy.


		• Second, you can complete, execute and deliver a new, later-dated proxy card for the same shares. If you submitted the proxy you are seeking to revoke via the Internet or telephone, you may submit a later-dated new proxy using the same method of transmission (Internet or telephone) as the proxy being revoked.

		• Third, you can attend the special meeting and vote in person.

		If you choose the first method or submit a new later-dated proxy card, we must receive your notice of revocation or your new proxy card prior to the commencement of the special meeting. If you submit a new later-dated proxy via the Internet or telephone, we must receive our new proxy by p.m., Eastern Time, 2008.

		Simply attending the special meeting will not revoke your proxy; you must vote at the meeting. If you have instructed a broker or bank to vote your shares, you must follow directions received from your broker or bank to change your vote.

Q12:		Should I send in my stock certificates now?

A12:		No. After the merger is completed, you will receive written instructions for exchanging your stock certificates for the merger consideration of $61.50 per share in cash, without interest and less any applicable withholding tax. You should not send any stock certificates with your proxy .

Q13:		What should I do now?

A13:		After you read and consider carefully the information contained in this proxy statement, please submit your proxy as soon as possible so that your shares of EnergySouth common stock may be represented at the special meeting. If your shares are registered in your own name, you may submit your proxy by filling out and signing the proxy card and then mailing your signed proxy card in the enclosed envelope or by submitting your proxy via the Internet or telephone. If your shares are held in “street name,” you should follow the directions your broker or bank provides. Please do not send in your stock certificates with your proxy.

Q14:		What happens if I sell my shares before the special meeting?

A14:		The record date for the special meeting, [•], 2008, is earlier than the date of the special meeting. If you held your shares on the record date but transfer them prior to the effective time of the merger, you may retain your right to vote at the special meeting but not the right to receive the merger consideration for the shares. The right to receive such consideration will pass to the person who owns your shares when the merger becomes effective.

Q15:		Am I entitled to appraisal rights?

A15:		Yes. You may dissent from adoption of the merger agreement and approval of the merger and obtain a cash payment for the fair value of your shares as determined by a court. To exercise appraisal rights, you must NOT vote in favor of the adoption of the merger agreement and approval of the merger, and you must strictly comply with all of the applicable requirements of Delaware law. If a proxy is dated, signed and returned without indicating voting instructions for a matter coming before the special meeting, shares represented by the proxy will be voted “FOR” that matter. The fair value of your shares, as determined by a court, may be more than, less than or equal to the $61.50 per share to be paid to stockholders pursuant to the merger agreement.

Q16:		What are the federal income tax consequences of the receipt of cash in the merger?

A16:		The receipt of cash for EnergySouth common stock in the merger will be a taxable transaction for U.S. federal income tax purposes. You generally will recognize taxable gain or loss equal to the difference between $61.50 per share and your tax basis for your EnergySouth common stock. Any capital gain or loss will be long-term capital gain or loss if your holding period for the shares is more than one year.

		The tax consequences of the merger to you will depend on the facts of your own situation. You should consult your own tax advisor for a full understanding of the tax consequences of the merger to you, including the application of state, local, foreign or other tax laws.


Q17:		When do you expect the merger to be completed?

A17:		We are working towards completing the merger as soon as possible. Assuming timely satisfaction of necessary closing conditions, we expect the merger to be completed in the fourth calendar quarter of 2008.

Q18:		When will I receive the cash payment for my shares?

A18:		Assuming that you elect not to exercise your appraisal rights, shortly after the effective time of the merger, [ ] , the paying agent, will send to you a letter of transmittal with instructions regarding the surrender of your share certificates in exchange for the merger consideration. Once you have delivered an executed copy of the letter of transmittal together with your share certificates, [ ] will promptly pay the merger consideration to you, less any applicable withholding taxes.

Q19:		What happens if the merger is not completed?

A19:		If the merger agreement is not adopted by our stockholders or if the merger is not completed for any other reason, stockholders will not receive any payment for their shares in connection with the merger. Instead, we will remain a public company and our common stock will continue to be listed and traded on the Nasdaq Global Select Market. Under specified circumstances, we may be required to pay Sempra Energy a termination fee as described under “The Merger Agreement — Termination Fees and Expenses.”

Q20:		Where can I find more information about EnergySouth?

A20:		We file reports, proxy statements and other information with the Securities and Exchange Commission, referred to as the SEC, under the Securities Exchange Act of 1934, as amended, or the Exchange Act. You may read and copy this information at the SEC’s public reference facilities. You may call the SEC at 1-800-SEC-0330 for information about these facilities. This information is also available at the Internet site the SEC maintains at www.sec.gov. You can also request copies of these documents from us.

Q21:		Who can help answer my other questions?

A21:		If you would like additional copies, without charge, of this proxy statement or if you have questions about the merger, including the procedures for voting your shares, you may contact us by telephone at (251) 450-4631 or in writing at P.O. Box 2248, Mobile, Alabama 36652, Attention: Martha Loper, Investor Relations.

The Special Meeting (See page )


•	*Date, Time and Place (See page )*

The special meeting is scheduled to take place on [ • ], 2008, at 10:00 a.m., local time, at the Auditorium at the principal office of the Company, 2828 Dauphin Street, Mobile, Alabama.

• Matters to be Considered at the Special Meeting (See page )

At the special meeting, you will be asked to vote on a proposal to adopt the merger agreement and approve the merger. Pursuant to the merger agreement:


	•	Merger Sub will merge into EnergySouth, with EnergySouth continuing as the surviving corporation; and

	•	each outstanding share of our common stock will be cancelled and converted into the right to receive $61.50 in cash, without interest and less any applicable withholding tax, except for shares held by stockholders who


		properly perfect their appraisal rights in accordance with Delaware law and shares held by EnergySouth, Sempra Energy or Merger Sub or their respective subsidiaries.

You may also be asked to vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies in support of the proposal to adopt the merger agreement and approve the merger if there are not sufficient votes at the special meeting to do so.


•	*Record Date and Voting Information (See page )*

You are entitled to vote at the special meeting if you owned shares of our common stock as of the close of business on [ • ], 2008, which is the record date for the special meeting. You will have one vote at the special meeting for each share of EnergySouth common stock you owned at the close of business on the record date. On the record date, there were [ • ] shares of EnergySouth common stock issued, outstanding and entitled to vote at the special meeting.


•	*Required Vote (See page )*

Adoption of the merger agreement and approval of the merger requires the affirmative vote of the holders of a majority of the outstanding shares of our common stock entitled to vote on the merger. Failures to vote, abstentions and broker non-votes (meaning proxies submitted by brokers or banks as holders of record on behalf of their customers that do not indicate how to vote on a non-routine proposal such as the vote on the merger) will have the effect of a vote “AGAINST” the adoption of the merger agreement and approval of the merger.

Adjournment of the special meeting, if necessary, to solicit additional proxies requires the affirmative vote of the holders of a majority of the shares of our common stock present in person or represented by proxy and entitled to vote at the special meeting. Abstentions will have the effect of a vote “AGAINST” the proposal to adjourn the special meeting for the solicitation of additional proxies, but a failure to vote will have no effect on the proposal to adjourn the special meeting.


•	*Voting by Proxy (See page )*

After carefully reading and considering the information contained in this proxy statement, you should respond by completing, signing and dating your proxy card and returning it in the enclosed postage-prepaid envelope or by submitting your proxy via the Internet or telephone as soon as possible so that your shares may be represented at the special meeting.

If you hold your shares in “street name” (that is, through a broker, bank or other nominee), your broker or bank will not be able to vote your shares on the proposal to adopt the merger agreement and approve the merger without instructions from you. You should instruct your broker or bank to vote your shares by following the procedure provided by your broker or bank. Without instructions, your shares will not be voted for that proposal, which will have the same effect as if you voted “AGAINST” adoption of the merger agreement and approval of the merger. Your broker or bank will be able to vote your shares in its discretion on the proposal to adjourn the special meeting if necessary, even if you do not provide instructions to your broker or bank on how to vote.

If you vote by proxy, you may still revoke your proxy in one of three ways:


	•	First, you can send a written notice to the Secretary of EnergySouth stating that you would like to revoke your proxy.

	•	Second, you can complete, execute and deliver a new, later-dated proxy card for the same shares. If you submitted the proxy you are seeking to revoke via the Internet or telephone, you may submit a later-dated new proxy using the same method of transmission (Internet or telephone) as the proxy being revoked.

	•	Third, you can attend the special meeting and vote in person.

If you choose the first method or submit a new later-dated proxy card, we must receive your notice of revocation or your new proxy card prior to the commencement of the special meeting. If you submit a new later-

dated proxy via the Internet or telephone, we must receive your new proxy by p.m., Eastern Time, 2008.

The Merger and the Merger Agreement (See page , page and Annex A)


•	*Reasons for the Merger (See page )*

The principal purpose of the merger is to permit our stockholders to realize a cash value for their shares of EnergySouth common stock at a 22.6% premium over the last reported sale of our common stock before the public announcement of the execution of the merger agreement on July 28, 2008 and a 21.8% premium over the average reported last sale price of our common stock over the 90 day period prior to July 23, 2008. Our board of directors believes that the merger offers our stockholders the greatest value for their shares in light of our long-term prospects and the available strategic alternatives.


•	*Merger Consideration (See page )*

If the merger is completed, each share of EnergySouth common stock owned by you at the effective time of the merger will be automatically cancelled and converted into the right to receive $61.50 in cash, without interest and less any applicable withholding tax; except that, alternatively, if you perfect your appraisal rights in accordance with Delaware law, your shares will be subject to appraisal by a court in accordance with Delaware law.


•	*Treatment of Options and Other Equity Awards (See page )*

Each outstanding option to acquire EnergySouth common stock (whether vested or unvested) which is not exercised will be cancelled at the effective time of the merger in exchange for a cash payment, without interest, equal to the product of (1) the number of shares of EnergySouth common stock subject to such option multiplied by (2) the amount that $61.50 exceeds the option exercise price per share of common stock subject to such option, less any required withholding taxes.


•	*Recommendation of the Board of Directors (See page )*

Our board of directors has unanimously approved the merger agreement and declared the merger agreement and the merger advisable and in the best interests of EnergySouth stockholders. Our board of directors unanimously recommends that you vote “FOR” adoption of the merger agreement and approval of the merger and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Morgan Securities Inc., which we refer to as JPMorgan, has rendered an opinion to the board of directors, that as of July 25, 2008 and based upon and subject to the various considerations set forth in the JPMorgan opinion letter, the consideration to be paid to the holders of EnergySouth common stock in the merger was fair, from a financial point of view, to such holders. The full text of JPMorgan’s written opinion, dated July 25, 2008, which sets forth, among other things, assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by JPMorgan in rendering its opinion, is attached as Annex B to this proxy statement and is incorporated into this proxy statement by reference. JPMorgan provided its opinion for the information and assistance of the board of directors in connection with its evaluation of the merger, and its opinion is not a recommendation as to how any stockholder should vote with respect to the merger or any other matter.


•	*Financing (See page )*

Payment by Sempra Energy of the cash merger price of $61.50 per share is not subject to any financing conditions or contingencies. Sempra Energy has represented to us that it has sufficient cash available, either through cash on hand or through committed availability under existing credit facilities, to pay the aggregate cash merger consideration.


•	*Conditions to the Merger (See page )*

Before completion of the merger, certain closing conditions must be satisfied or waived. These conditions are discussed in detail under “The Merger Agreement — Conditions to the Merger” and include, among others:


	•	adoption of the merger agreement and the approval of the merger by our stockholders;

	•	the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act;

	•	the receipt of any necessary approvals from the Federal Communications Commission; and

	•	other customary closing conditions.


•	*Acquisition Proposals (See page )*

We have agreed that neither we, nor any of our subsidiaries nor any of our representatives will directly or indirectly solicit, initiate, knowingly encourage or knowingly facilitate a third party takeover proposal or participate in negotiations with respect to such a takeover proposal. However, in certain circumstances we are permitted to engage in negotiations with and furnish nonpublic information to a third party that makes a bona fide written takeover proposal so long as:


	•	our board of directors reasonably determines in good faith that the takeover proposal is or is reasonably likely to result in a superior proposal; and

	•	our board of directors concludes in good faith that the failure to engage in negotiations or furnish nonpublic information would be inconsistent with its fiduciary duties to our stockholders.

Our board of directors is generally not permitted to change adversely its recommendation in favor of the adoption of the merger agreement and approval of the merger or to adopt or recommend any competing takeover proposal unless:


	•	our board of directors concludes that the takeover proposal constitutes a superior proposal;

	•	we give Sempra Energy and Merger Sub at least four business days prior written notice that our board of directors has received a superior proposal and intends to change its recommendation; and

	•	if requested by Sempra Energy, we negotiate with Sempra Energy and Merger Sub during such four-day notice period to make adjustments to the terms and conditions of the merger agreement so that the takeover proposal ceases to be a superior proposal.


•	*Termination of the Merger Agreement (See page )*

Subject to certain exceptions, the merger agreement may be terminated and the merger abandoned at any time prior to the effective time of the merger in any of the following ways:


	•	by mutual written consent of Sempra Energy, Merger Sub and us;

	•	by either us or Sempra Energy in the event that any law or order permanently restraining, enjoining or otherwise preventing the consummation of the merger becomes final and nonappealable;

	•	by either us or Sempra Energy if the merger is not consummated by April 30, 2009, if the failure to consummate the merger on or before such date is not caused by a breach of obligations under the merger agreement by the party seeking to terminate;

	•	by either us or Sempra Energy in the event of certain breaches by the other party of any representation, warranty, covenant or agreement contained in the merger agreement;

	•	by either us or Sempra Energy in the event that our stockholders do not adopt the merger agreement and approve the merger at the special meeting, if the failure to obtain stockholder approval is not caused by a breach of obligations under the merger agreement by the party seeking to terminate;


	•	by Sempra Energy in the event that our board of directors adversely changes its recommendation in favor of the adoption of the merger agreement and the approval of the merger; or

	•	by us, in order to accept a superior proposal subject to certain terms and conditions and the payment of a termination fee by us to Sempra Energy.

	•	*Termination Fees and Expenses (See page )*

The merger agreement provides that, in general, all direct costs and expenses incurred by the parties in connection with the merger agreement and the merger will be borne by the party incurring such cost or expense. The merger agreement requires, however, that we pay Sempra Energy a termination fee of $25 million if:


	•	Sempra Energy terminates the merger agreement because our board of directors adversely changes its recommendation in favor of the adoption of the merger agreement and the approval of the merger;

	•	we terminate the merger agreement in order to accept a superior proposal; or

	•	any of the following terminations of the merger agreement occur and, within nine months of the date of such termination, we enter into a definitive contract to consummate, or we consummate, the transactions contemplated by any third party takeover proposal:


	•	Sempra Energy terminates the merger agreement because of our breach of one or more of our representations, warranties or covenants under the merger agreement and, prior to our breach, a third party takeover proposal was publicly announced or was otherwise publicly known;

	•	either we or Sempra Energy terminates the merger agreement because the merger has not been consummated by April 30, 2009 and, prior to such termination, a third party takeover proposal was publicly announced or was otherwise publicly known; or

	•	either we or Sempra Energy terminates the merger agreement because our stockholders do not adopt the merger agreement and approve the merger and, prior to the special meeting, a third party takeover proposal was publicly announced or was otherwise publicly known.


•	*Market Price of EnergySouth Common Stock (See page )*

The closing sale price of EnergySouth common stock on the Nasdaq Global Select Market on July 25, 2008, the last trading day prior the public announcement of the execution of the merger agreement, was $50.16 per share. The $61.50 per share in cash to be paid as merger consideration constituted a 22.6% premium to the closing price on July 25, 2008.

RISK FACTORS AND SPECIAL CAUTIONARY NOTICE REGARDING
FORWARD-LOOKING STATEMENTS

Completion of the merger is subject to various risks, including, but not limited to the following:


	•	stockholders holding a majority of the outstanding shares of our common stock might not vote to adopt the merger agreement and approve the merger;

	•	failure to obtain regulatory approvals to complete the merger, including required antitrust approvals and any required approval of the Federal Communications Commission;

	•	the occurrence of any change, effect, event or development that could give rise to the termination of the merger agreement;

	•	the initiation of governmental or regulatory action or legislation prohibiting the merger or the other transactions contemplated by the merger agreement; and

	•	the failure to meet any other closing condition in the merger agreement.

As a result of these risks, there can be no assurance that the merger will be completed.

This proxy statement, including the documents incorporated by reference in it, contains forward-looking statements, which you can identify by forward-looking words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “grow,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “strive,” “will” and similar expressions that convey uncertainty of future events or outcomes. Although we believe that the beliefs, expectations, goals, objectives, plans and prospects reflected in or suggested by our forward-looking statements are reasonable in view of the information currently available to us, those statements are not guarantees of performance. They involve uncertainties and risks, including but not limited to those set forth in the bullets above, and we cannot assure you that our beliefs, expectations, goals, objectives, plans and prospects will be achieved. Actual results may differ materially from those in our forward-looking statements.

Any forward-looking statement contained in this proxy statement or in the documents to which we refer speaks only as of the date it was made. We undertake no obligation to publicly update or revise any forward-looking statement that we may make in this proxy statement or elsewhere except as required by law.

If the merger is not completed for any reason, we expect that our board of directors and current management will continue to manage EnergySouth as an ongoing business. You should review the risk factors contained in our annual report on Form 10-K/A for the fiscal year ended September 30, 2007, incorporated by reference into this proxy statement, for a description of the risk factors associated with the continued operation of our business.

THE SPECIAL MEETING

Date, Time and Place

This proxy statement is furnished in connection with the solicitation of proxies by the EnergySouth board of directors for a special meeting of holders of our common stock to be held on [ • ] , 2008 at 10:00 a.m., local time, at the Auditorium at the principal office of the Company, 2828 Dauphin Street, Mobile, Alabama 36606, or at any adjournment of the special meeting.

Matters to be Considered

The purpose of the special meeting is to consider and vote upon proposals to (1) adopt the Agreement and Plan of Merger, dated as of July 25, 2008, by and among Sempra Energy, EMS Holding Corp. and EnergySouth, and approve the merger contemplated therein, pursuant to which EnergySouth will become a wholly-owned indirect subsidiary of Sempra Energy and each share of EnergySouth common stock will be converted into the right to receive $61.50 in cash, without interest and less any applicable withholding tax, and (2) adjourn the special meeting, if necessary or appropriate, to solicit additional proxies in support of the proposal to adopt the merger agreement and approve the merger if there are not sufficient votes at the special meeting to do so.

Record Date, Outstanding Voting Securities, Voting Rights and Quorum

Our board of directors has set the close of business on [ • ] , 2008 as the record date for determining stockholders of EnergySouth entitled to notice of, and to vote at, the special meeting. As of the record date, there were [ • ] shares of common stock outstanding. Each outstanding share entitles its holder to one vote on all matters properly coming before the special meeting. Any stockholder entitled to vote may vote either in person or by properly executed proxy. A majority of the outstanding shares of common stock entitled to vote, present in person or represented by proxy, will constitute a quorum at the special meeting. Abstentions and broker non-votes will be counted for the purpose of establishing a quorum at the special meeting.

Required Votes, Abstentions and Broker Non-Votes

Adoption of the merger agreement and approval of the merger requires the affirmative vote of the holders of a majority of the outstanding shares of EnergySouth common stock entitled to vote at the special meeting. Adjournment of the special meeting, if necessary, to solicit additional proxies requires the affirmative vote of the holders of a majority of the shares of EnergySouth common stock present in person or represented by proxy at the special meeting, whether or not a quorum is present.

Failure to vote, abstentions and broker non-votes (meaning proxies submitted by brokers or banks as holders of record on behalf of their customers that do not indicate how to vote on a non-routine proposal such as the vote on the merger) will have the effect of a vote “AGAINST” the adoption of the merger agreement and approval of the merger. Abstentions also will have the effect of a vote “AGAINST” the proposal to adjourn the special meeting for the solicitation of additional proxies, but a failure to vote will have no effect on the proposal to adjourn the special meeting. Because the proposal to adjourn the special meeting is a routine proposal, there will be no broker non-votes with regard to it.

Shares Beneficially Owned by EnergySouth Directors and Officers

EnergySouth’s directors and executive officers beneficially owned [990,151] shares of EnergySouth common stock on [ • ] , 2008, the record date for the special meeting. These shares represent in total approximately [11.9]% of the shares of EnergySouth common stock outstanding and entitled to vote as of the record date for the special meeting. Although none of the members of the board of directors or the executive officers have executed voting agreements, based solely on its discussions with its board of directors and executive officers, EnergySouth currently expects that all of its directors and executive officers will vote their shares in favor of the adoption of the merger agreement and approval of the merger.

Proxies, Revocation

If your shares are registered in your name, you may cause your shares to be voted by returning a signed proxy card or may vote in person at the special meeting. Additionally, you may submit a proxy authorizing the voting of your shares over the Internet or telephonically. You must have the enclosed proxy card available and follow the instructions on the proxy card, in order to submit a proxy over the Internet or telephone. Based on your Internet and telephone proxies, the proxy holders will vote your shares according to your directions. If you plan to attend the special meeting and wish to vote in person, you will be given a ballot at the meeting. If your shares are registered in your name, you are encouraged to vote by proxy even if you plan to attend the special meeting in person.

Shares that are entitled to vote and are represented by a properly submitted proxy that is received at or prior to the special meeting, unless subsequently properly revoked, will be voted in accordance with the instructions indicated thereon. If a proxy is dated, signed and returned without indicating voting instructions for a matter coming before the special meeting, shares represented by the proxy will be voted “FOR” that matter. The board of directors is not currently aware of any business to be acted upon at the special meeting other than as described in this proxy statement.

If your shares are held in “street name” through a broker or bank, you may vote through your broker or bank by completing and returning the voting form provided by your broker or bank, or via the Internet or telephone through your broker or bank if such a service is provided. If your shares are held in “street name” through a broker or bank

and you wish to attend the special meeting and vote in person, you will need to obtain a proxy from your broker or bank. If you do not return your bank’s or broker’s voting form, do not vote via the Internet or telephone through your broker or bank, if possible, or do not attend the special meeting and vote in person with a proxy from your broker or bank, it will have the same effect as if you voted “AGAINST” adoption of the merger agreement and the approval of the merger.

If you have submitted a proxy, you may revoke it by:


	•	delivering a later-dated, signed proxy card or a written revocation of such proxy to:

EnergySouth, Inc.
P.O. Box 2248
Mobile, Alabama 36652
Attention: G. Edgar Downing, Jr., Secretary
(251) 450-4631, or


	•	if such proxy was submitted via the Internet or telephone, submitting a new later-dated proxy using the same method of transmission (Internet or telephone) as the proxy being revoked or

	•	attending the special meeting and voting in person.

If you choose the first method, we must receive your new proxy card or your notice of revocation before the start of the special meeting. If you choose the second method, we must receive your new proxy by p.m., Eastern Time, on 2008. With regard to the third method, attendance at the special meeting will not by itself constitute the revocation of a proxy; to revoke a proxy in person at the special meeting you must vote in person at the meeting.

If you have instructed a broker or bank to vote your shares, follow the directions received from your broker or bank to change your vote.

Expenses of Proxy Solicitation

EnergySouth will bear the expenses in connection with the solicitation of proxies. Upon request, we will reimburse brokers and banks, or their nominees, for reasonable expenses incurred in forwarding copies of the proxy materials to the beneficial owners of shares of EnergySouth common stock that such persons hold of record. Solicitation of proxies will be made principally by mail. Proxies may also be solicited in person or by telephone, fax, or email by our officers and employees. Such persons will receive no additional compensation for these services but will be reimbursed for any transaction expenses incurred by them in connection with these services.

We have engaged Morrow & Co., Inc. as our proxy solicitor to assist in the dissemination of proxy materials and in obtaining proxies and to answer your questions. We will pay them $8,500 and reimburse them for their expenses.

THE MERGER (PROPOSAL NO. 1)

Background of the Merger

As part of their ongoing management and oversight of our business, the board of directors and senior management regularly review and discuss EnergySouth’s business, strategic direction, performance and long range plans with a view toward actions that will increase stockholder value. Over the last several years, EnergySouth has been transitioning from a pure-play natural gas utility, Mobile Gas, to a company focused primarily on the natural gas midstream business, with a particular emphasis on the development of salt dome caverns for the storage of natural gas through its wholly-owned Midstream subsidiary.

The strategic plan for EnergySouth developed by management and approved by the board in October 2006 called for the aggressive growth of the Midstream business. However, the board and management also recognized that the implementation of this strategic plan would significantly increase EnergySouth’s short-term and long-term

capital needs and subject us to a number of risks associated with the expansion of the Midstream business. These risks would include:


	•	the potential inability to obtain on acceptable terms debt and equity financing required to execute our strategic plan;

	•	the potential inability to enter into storage agreements with creditworthy third parties on a timely basis;

	•	changing market conditions that could impact demand and prices for natural gas storage in the Gulf Coast region; and

	•	potential increases in development costs associated with the construction of salt dome caverns, surface facilities and related pipelines.

In the fall of 2007, we entered into an agreement to purchase 60% of Mississippi Hub LLC, a natural gas storage cavern facility under development. In anticipation of the closing of this acquisition, a special meeting of the board of directors was held on October 1, 2007. At this meeting, the board authorized us to enter into a new $195 million, 364-day revolving credit facility. The board acknowledged, however, that this was only a short-term solution and that permanent financing would have to be obtained. The board discussed a number of alternatives for permanent financing, including the issuance of equity by EnergySouth, the creation of a master limited partnership consisting primarily of our Midstream business or the sale of Mobile Gas.

At a regularly scheduled board meeting held on October 26, 2007, at the invitation of management, representatives from JPMorgan, one of the lenders under our credit facility, made a presentation to the board regarding long-term financing alternatives. The board, senior management and representatives from JPMorgan discussed a number of financing alternatives, including increased leverage, the issuance of common stock, the creation of a master limited partnership, the sale of Mobile Gas and entering into a financial relationship with a private equity investor.

On December 7, 2007 at a regularly scheduled board meeting, the board continued its discussion of long-term financing alternatives. At the recommendation of management, the board authorized us to retain Berenson & Company, a leading investment banking firm with a prominent energy practice, in connection with a general financial advisory engagement. We entered into an engagement letter with Berenson regarding that engagement later that day.

In January 2008, C.S. Liollio, our President and Chief Executive Officer, was contacted by representatives from a leading private equity firm who expressed an interest in exploring an acquisition of EnergySouth at a preliminary valuation of between $65 and $70 per share. This proposal was made prior to the private equity firm having conducted, and was subject to the completion of, substantial due diligence, as well as the negotiation of definitive documentation and obtaining suitable financing. Mr. Liollio immediately advised the members of the board of this proposal. The board subsequently authorized us to enter into a confidentiality agreement, which was executed on January 23, 2008, and an exclusive negotiation agreement, which was entered into on January 24, 2008, providing for a 30-day exclusivity period during which the private equity firm would perform due diligence on EnergySouth. On March 5, 2008, the private equity firm advised us that although it remained interested in EnergySouth, the continued deterioration of conditions in the financial markets made it unable to make a definitive proposal for a transaction with EnergySouth at that time.

We continued to evaluate long-term financing alternatives and as a part of that effort, on March 10, 2008, we entered into a new agreement with Berenson to serve as our financial advisor in connection with any proposed sale of all or a substantial portion of the assets of Mobile Gas. This agreement replaced the engagement letter entered into on December 7, 2007.

As part of our ongoing evaluation of financing alternatives, we continued to evaluate a potential issuance of debt or equity. On March 14, 2008, a special meeting of the board of directors was held, with senior management present. At this meeting, Charles P. Huffman, our Executive Vice President and Chief Financial Officer, discussed with the board both short-term and long-term financing needs. As part of this discussion, recent developments were reviewed including the results of a marketing “open season” at our Mississippi Hub facility, escalating capital costs and the upcoming need to construct additional pipelines to coincide with the completion of the first storage cavern at

Mississippi Hub. Mr. Huffman also discussed EnergySouth’s corporate structure and the nature of borrowings that had been done at the various subsidiaries, as well as the potential for further borrowings. Cash needs and sources for each subsidiary were reviewed and discussed as well as projected in-service dates for the Midstream business’ storage caverns at both Mississippi Hub and Bay Gas. At this meeting, the board approved the filing of a universal shelf registration statement with the SEC to enable us to access alternative sources of financing.

Also at this meeting the board discussed the possibility of merging EnergySouth with a buyer that would have greater financial resources with which to execute our development plan for Midstream. The board noted that such a transaction would potentially allow our stockholders to receive a premium for their shares of common stock, while at the same time avoiding the significant development risks associated with Midstream. To that end, the board authorized management to retain the services of Berenson and JPMorgan to conduct a structured bid solicitation process to determine the viability of a potential sale of EnergySouth or Mobile Gas. The board also established a special committee of the board, consisting initially of John C. Hope (chairman), Harris V. Morrissette and J.D. Woodward, as a committee of convenience to interact with our financial advisors and to review and analyze their recommendations and to report to the board on both developments and their recommendations.

During March and April 2008, senior management worked with representatives of Berenson and JPMorgan to prepare a confidential descriptive memorandum regarding EnergySouth and the structured bid solicitation process, as well as a financial model for EnergySouth and an electronic data room for potential bidders.

On April 7, 2008, we entered into engagement letters with Berenson and JPMorgan to serve as joint financial advisors to us in connection with a possible sale of EnergySouth or Mobile Gas.

During the fourth week of April 2008, representatives of Berenson and JPMorgan contacted potential strategic and financial buyers to inquire about their interest in submitting indications of interest.

On April 25 and 26, 2008, at a regularly scheduled board meeting at which senior management was present, representatives of Berenson and JPMorgan reported to the board on the expected timeline for the bid solicitation process. A review of 22 potentially interested strategic and financial buyers, which did not include Sempra Energy, was provided, with a focus on both competitive issues and the ability of these parties to meet financial obligations within the timeframe of the process. The financial advisors noted that in view of the current conditions in the credit markets, it might be difficult for financial buyers such as private equity firms to be competitive. The financial advisors also presented an overview of recent purchase and sale transactions in the natural gas industry.

A representative of Alston & Bird LLP, one of our two outside law firms, then reviewed with the directors a previously distributed memorandum discussing the board’s fiduciary duties under Delaware law in considering a business combination or sale of the business. Mr. Huffman updated the board regarding our financial needs and discussed the impact of issuing equity. Mr. Huffman also discussed the financial impact of a sale of Mobile Gas, noting that in such event, we likely would need to reduce the amount of or eliminate our regular cash dividend and would still need to issue equity to finance the planned growth of the Midstream business. Mr. Huffman and the representatives of Berenson, JPMorgan and Alston & Bird responded to questions from the directors.

The board of directors then discussed the outlook for EnergySouth and the benefits and risks associated with continuing to operate EnergySouth as a stand-alone entity and selling common stock to the public to raise capital, selling EnergySouth or selling Mobile Gas. Following this discussion, the board unanimously concluded that a sale of EnergySouth was the preferred alternative for maximizing stockholder value, followed by a sale of Mobile Gas as an alternative strategy. The board then authorized management to continue to work with Berenson and JPMorgan to pursue these strategies and appointed Robert H. Rouse as a fourth member of the special committee.

In the first and second weeks of May 2008, Berenson and JPMorgan distributed, to interested parties that had executed confidentiality agreements, the descriptive memorandum and a bid procedures letter requesting the submission of written initial non-binding indications of interest for the purchase of EnergySouth.

On May 22, 2008, at a meeting of the special committee at which members of senior management were present, representatives from Berenson and JPMorgan provided the committee with an overview of the solicitation process to date. The financial advisors reported that 24 parties had now been contacted and that the descriptive memorandum had been distributed to 17 of those parties. Five of these parties had submitted written initial non-

binding proposals to acquire the entire Company (from three bidders) or Mobile Gas (from two bidders). The three proposals to acquire EnergySouth had implied prices ranging from $58 to $64 per share in cash, were not subject to any financing condition and were generally subject to further due diligence, negotiation of mutually acceptable definitive agreements and other standard conditions.

The financial advisors reviewed the proposals of each of these five bidders with the special committee, followed by a discussion of a preliminary valuation of EnergySouth prepared by Berenson and JPMorgan. The committee members, with input from the financial advisors, then discussed at length the advantages and the disadvantages of continuing to operate EnergySouth on a stand-alone basis and selling common stock in a public offering, selling Mobile Gas or selling EnergySouth. The special committee unanimously determined that it was in the best interests of the stockholders to continue to pursue a sale of EnergySouth or, failing that, Mobile Gas. The committee then unanimously determined to allow four entities to proceed to the second round of the process.

On May 27, 2008, the financial advisors invited these four bidders to participate in the second round of the process, and the four parties were invited to a presentation by our management, were invited to visit our facilities and were granted access to an electronic data room for a detailed review of due diligence materials.

On May 27, 2008, another party who had previously been contacted by the financial advisors, but had not executed a confidentiality agreement, expressed an interest in participating in the bid solicitation process. After consultation with our board of directors, Mr. Liollio instructed the financial advisors to invite this party to participate in the process. On May 28, 2008, this party executed a confidentiality agreement and was furnished a copy of the descriptive memorandum. On May 30, 2008, this party made a preliminary proposal containing a preliminary bid of $62 per share, subject to further due diligence and other standard conditions. Based upon that preliminary proposal, this party was invited to participate in the second round of the process and was granted access to our electronic data room, as well as invited to a presentation by our management.

On May 28, 2008, representatives of Sempra Energy contacted Berenson and JPMorgan, expressing an interest in participating in the bid solicitation process. After consultation with our board of directors, Mr. Liollio instructed the financial advisors to invite Sempra Energy to participate in the process. On May 30, 2008, Sempra Energy executed a confidentiality agreement and was furnished a copy of the descriptive memorandum. On June 3, 2008, Sempra Energy made a preliminary proposal containing a preliminary bid range of $62 to $65 per share, subject to further due diligence and other standard conditions. Based upon that preliminary proposal, Sempra Energy was invited to participate in the second round of the process and was granted access to our electronic data room, as well as invited to a presentation by our management.

Throughout June and the first two weeks of July 2008, these six potential bidders accessed the electronic data room materials for operational, financial, accounting, tax, legal and other business due diligence. During the weeks of June 9 and 16, 2008, members of senior management made in-person management presentations to each of the six second round participants, including Sempra Energy. These management presentations generally included an overview of EnergySouth and its two business segments, the markets in which the two segments compete, and summary financial information. For bidders interested in Mobile Gas, the management presentation related only to that business. Members of our management team held additional, follow up due diligence meetings, in person and by telephone, with representatives from each of these six parties.

On June 18, 2008, Berenson and JPMorgan invited each of the six bidders to submit a firm and binding written offer for the purchase of EnergySouth. Alston & Bird then distributed a draft merger agreement to each of the six bidders for their review and comment.

On July 1, 2008, another party informed JPMorgan that it would like to either acquire Mobile Gas or to partner with another entity that desired to acquire the Midstream business so that it and such other entity would severally, but not jointly, purchase the entire Company. In response to this letter and after consultation with the financial advisors and the board of directors, as well as after execution of a confidentiality agreement, Mr. Liollio on July 2, 2008 instructed JPMorgan to arrange a management presentation for this party. On July 11, 2008, Mr. Downing, Mr. Huffman and Mr. Welch participated in a telephonic management presentation to senior management of this party. However, this party did not subsequently present a proposal for a transaction regarding EnergySouth or Mobile Gas.

On July 11, 2008, Sempra Energy and one other bidder submitted final offers to Berenson and JPMorgan and provided comments on the proposed form of merger agreement. Sempra Energy’s offer of $58.35 per share in cash was higher than the cash offer proposed by the other bidder and represented a 30% premium over the closing price of our common stock on July 10, 2008. Neither bidder’s offer contained a financing contingency. Both bidders confirmed that they had substantially completed their due diligence and were prepared to move quickly to a closing. Sempra Energy’s offer had been approved by its board of directors, but the other bidder’s offer was still subject to its board’s approval. A third bidder provided a range of prices that it might be willing to offer, but this range was significantly lower than the two final offers that had been received. This party did not submit a final offer.

On July 15, 2008 a meeting of the special committee was held, with senior management present, to discuss the terms and conditions of the two final bids for EnergySouth. Representatives of Berenson and JPMorgan reviewed the financial terms of the two offers, and a representative of Alston & Bird reviewed the material terms of the draft merger agreements submitted with the two offers, including the transaction structure, the treatment of stock options, performance share awards and stock unit awards, required approvals, our ability to accept a superior proposal, the match rights requested by the buyers, the conditions under which the merger agreement could be terminated and the termination fee that we could be required to pay under specified circumstances. The committee again discussed the three strategic alternatives available to EnergySouth. It was determined that if an acceptable agreement could be reached with Sempra Energy, it would represent the best course of action for the stockholders by allowing them to recognize a significant premium over the current price of the stock while eliminating their exposure to the development risks associated with the implementation of our strategic plan.

At the conclusion of these discussions, the special committee instructed Berenson and JPMorgan to contact representatives of Sempra Energy and inform them that while Sempra Energy’s bid of $58.35 per share was not acceptable, EnergySouth was willing to enter into an exclusivity agreement with Sempra Energy for a period ending at 5 p.m. Eastern time on July 25, 2008 to allow the parties to engage in further discussions to determine if an agreement on a price of at least $62.00 per share and other terms and conditions, including the amount of the termination fee payable under certain circumstances by EnergySouth to Sempra Energy, could be reached. On July 17, 2008, Sempra Energy proposed to increase its offer to $62.00 per share and the parties then entered into an exclusivity agreement prohibiting us from discussing an acquisition proposal with any third party during the exclusivity period.

On July 18, 2008, representatives of Sempra Energy, its outside counsel Latham & Watkins LLP, EnergySouth and Alston & Bird met to negotiate the provisions of the merger agreement. Subsequent to the meeting, the parties continued to negotiate the terms and conditions of the merger agreement, Sempra Energy continued its due diligence review of EnergySouth, and Sempra Energy and EnergySouth continued discussions regarding the offer price.

On July 23, 2008, as a result of its continuing due diligence and due to concerns expressed by Sempra Energy regarding certain contracts relating to our Midstream business, Sempra Energy proposed to reduce its offer price to $61.00 per share. Through its financial advisors, EnergySouth countered with a price of $61.75 per share, and on July 24, 2008, the parties agreed on a price of $61.50 per share. During this period, the parties continued to negotiate the final terms and provisions of the merger agreement.

On the afternoon of July 24, 2008, the special committee, with senior management present, met with representatives of Berenson, JPMorgan and Alston & Bird and reviewed the financial and other terms of the Sempra Energy offer. The financial advisors presented a financial analysis of the transaction and a valuation of EnergySouth based on current market conditions. At the conclusion of the meeting, the special committee voted unanimously to recommend to the board of directors that we execute a merger agreement with Sempra Energy on the terms proposed.

On the morning of July 25, 2008, the board of directors of EnergySouth met with representatives of Berenson, JPMorgan and Alston & Bird to discuss the proposed transaction. At this meeting, management and the outside advisors updated the directors on the status of the bid solicitation process and reported that substantially all issues regarding the transaction with Sempra Energy had been resolved, subject to approval by our board of directors. Representatives of Berenson and JPMorgan presented an in-depth review and analysis of the financial terms of the proposed transaction, including the transaction premium and implied multiples and their relationship to comparable

transactions, followed by an in-depth review and analysis of the current valuation of EnergySouth. JPMorgan then rendered an oral opinion to the board of directors, later confirmed by delivery of a written opinion dated July 25, 2008, that, as of that date and based on and subject to the factors and assumptions in its written opinion, the $61.50 per share in cash to be paid to the holders of our common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. A copy of the written opinion of JPMorgan is attached as Annex B to this proxy statement.

G. Edgar Downing, Jr., our Senior Vice President, Secretary and General Counsel, and a representative of Alston & Bird then reviewed the material terms of the merger agreement with the directors, including the transaction structure, the treatment of stock options, performance share awards and stock unit awards, the terms of our representations, warranties and covenants, required approvals, our ability to accept a superior proposal, the match right provided to Sempra Energy, the conditions under which the merger agreement could be terminated and the termination fee that we could be required to pay under specified circumstances. The board then considered and discussed various factors that favored approval of the proposed merger and various factors that weighed against or presented risks with regard to the proposed merger, substantially as summarized in “Recommendation of the Board of Directors and Reasons for the Merger” below. After further discussion, the board of directors, having determined that it was advisable, fair to and in the best interests of EnergySouth and its stockholders for EnergySouth to enter into and perform the merger agreement, unanimously resolved to approve the merger agreement and the merger and other transactions contemplated by the merger agreement, to authorize management to enter into the merger agreement, to direct that the merger agreement be submitted to our stockholders for approval and to recommend to our stockholders that they adopt the merger agreement and approve the merger.

Following the approval of the merger agreement and the merger by our board of directors, EnergySouth and Sempra Energy executed and delivered the merger agreement on the evening of Friday, July 25, 2008. On the morning of Monday, July 28, 2008, prior to the opening of the market, Sempra and EnergySouth issued a joint press release announcing the execution of the merger agreement.

Recommendation of the Board of Directors and Reasons for the Merger

At a meeting of our board of directors on July 25, 2008, after careful consideration, including consideration of the unanimous recommendation of the special committee and consultation with financial and legal advisors, our board of directors unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement are advisable and in the best interests of our stockholders.

Accordingly, our board of directors unanimously resolved to approve and adopt the merger agreement, to direct that it be submitted to our stockholders for approval, and to recommend to our stockholders that they vote “FOR” the adoption of the merger agreement and approval of the merger.

In the course of reaching its decision to approve the merger agreement and the merger and to recommend that our stockholders vote to adopt the merger agreement and approve the merger, our board of directors consulted with our senior management, financial advisors and legal counsel, reviewed a significant amount of information and considered a number of factors, including, among others, the following factors that supported approval of the merger:


	•	The Company’s Strategic Plan . The Company’s aggressive growth plans for its midstream business have inherent but largely unquantifiable risks, particularly with regard to our storage cavern development plan. Further, the Company will require significant amounts of capital over the next several years to implement these growth plans, but deteriorating conditions in the capital markets in the past year, which are not expected to improve in the reasonably foreseeable future, have severely limited the Company’s access to the necessary capital. As with any strategic plan, the successful execution of the Company’s growth plans are subject to a number of risks, many of which are exacerbated by the current volatility in the global credit and energy markets.

	•	The Company’s Financial and Operating Condition . The current and projected financial condition and results of operations of the Company and its two business segments, including the lower growth rate of the local distribution business and the projections for both high costs and high but uncertain growth and earnings


		in the midstream business, together with the current and potential economic and operating conditions in the various markets in which the Company conducts business, present significant challenges and uncertainties.


	•	Other Strategic Alternatives . The potential benefits, risks and uncertainties of the merger compare favorably with those associated with other strategic alternatives that are potentially available to the Company, including the possibility of being acquired by other companies, the possibility of acquisitions of or mergers, joint ventures or other transactions with other companies in the local distribution and/or midstream businesses, the possibility of selling one of our business segments and the possibility of raising additional equity capital and debt and remaining an independent public company.

	•	Financial Terms/Premium to Market Price . The merger consideration of $61.50 per share represented a premium of 26.7% over the $48.54 price per share of the Company’s common stock on the Nasdaq Global Select Market on July 23, 2008 and a 21.8% premium over the average reported last sale price of our common stock over the 90 day period prior to July 23, 2008.

	•	Highest Price Sempra Energy Will Offer . It was believed that $61.50 per share was the highest price that Sempra Energy would offer.

	•	Cash Consideration . The merger consideration is payable in cash, which provides certainty of value and complete liquidity to the stockholders, compared to a transaction in which the stockholders receive stock or another form of consideration.

	•	Opinion of Financial Advisor . JPMorgan provided a written opinion that as of July 25, 2008, based upon and subject to the factors and assumptions set forth in such opinion, the consideration to be received by the stockholders in the merger was fair, from a financial point of view, to the stockholders.

	•	Financial Analysis of the Merger . Berenson & Company and JPMorgan presented a detailed financial analysis of the merger to our board of directors on July 25, 2008.

	•	No Financing Condition . The merger is not subject to a financing condition, and Sempra Energy has significant financial capacity to consummate the merger.

	•	Likelihood of Consummation . The merger is likely to be consummated in light of the fact that (1) Sempra Energy has the financial ability and willingness to consummate the merger, (2) the merger is not subject to any financing contingency, (3) Sempra Energy has an excellent reputation in the market, which it would like to preserve, (4) the merger is subject to limited conditions and (5) the merger is likely to receive prompt regulatory clearance.

	•	Likelihood of Alternative Proposals . In light of (1) the structured three-month solicitation process conducted by the Company, with the assistance of Berenson & Company and JPMorgan, in which the two financial advisors approached 24 strategic and financial buyers likely to have the resources necessary to acquire the Company, of which seven submitted preliminary proposals to purchase the Company or one of its two businesses and two submitted final bids, and one additional company submitted a preliminary proposal to acquire our Mobile Gas business, and (2) the price offered by Sempra Energy, which was higher than the price offered by any other bidder, it appears unlikely that any party would propose an alternative transaction that would be more favorable to the Company and its stockholders than the merger.

	•	Ability to Receive and Consider Alternative Proposals . The terms of the merger agreement that permit the board of directors, in the exercise of its fiduciary duties, to consider bona fide written unsolicited acquisition proposals from third parties and to terminate the merger agreement to accept a superior proposal upon the payment by the Company of a $25 million termination fee, combined with the amount of time from the public announcement of the merger to the expected closing of the merger, are sufficient to permit the receipt of competing proposals from third parties.

	•	Timing for Obtaining Payment . The merger agreement enables the Company’s stockholders to receive the merger consideration at the earliest possible time consistent with applicable law, imposing no unusual delays.


	•	Availability of Dissenter’s Rights . Stockholders who do not vote in favor of the merger can obtain “fair value” for their shares, as determined by a court, if they properly perfect and exercise their dissenter’s rights in accordance with Delaware law.

	•	Future Operations of the Company . Sempra Energy has been successful in its business and operations and has an excellent reputation and significant financial strength, such that the transaction would be a favorable transaction for the Company’s employees, customers, suppliers and communities.

In the course of its deliberations, our board of directors also considered a variety of risks and other potentially negative factors, including the following:


	•	The Merger Might not be Completed . There is a risk that the merger might not be completed due to, among other things:


	•	The fact that Sempra Energy can terminate the merger agreement in certain circumstances, including for material breaches by the Company of its representations, warranties, covenants and agreements in the merger agreement, and

	•	The Company or Sempra Energy might not receive the regulatory approvals and clearances necessary to complete the merger, or governmental authorities could attempt to condition the merger on one or both parties’ compliance with certain burdensome conditions.


	•	Restrictions on Conduct of Business Prior to Completion of the Merger . The operating covenants in the merger agreement require the Company to conduct its business only in the ordinary course and subject to a variety of specific limitations prior to the closing of the merger or the termination of the merger agreement. These operating covenants may delay or prevent the Company from undertaking business opportunities that arise or may preclude actions that would be advisable if the Company were to remain an independent company and could even prevent the Company from realizing the profit inherent in some existing business arrangements.

	•	Potential Adverse Effects of Public Announcement on the Company . The public announcement of the merger could have an adverse effect on the Company’s business and competitive position prior to the completion of the merger or the termination of the merger agreement, including particularly on the Company’s relationships with its employees, customers, suppliers and the communities in which it operates.

	•	Potential Adverse Effects of Public Announcement on Others . The public announcement of the merger could have a direct adverse effect on the Company’s employees, customers, suppliers and the communities in which it operates.

	•	Restrictions on Soliciting Alternative Transactions . Under the merger agreement, the Company cannot solicit other acquisition proposals and must pay the $25 million termination fee if the merger agreement is terminated in certain circumstances, which in addition to being costly, could have the effect of discouraging other parties from proposing an alternative transaction that might be more advantageous to the Company’s stockholders than the merger.

	•	No Longer an Independent Company . Following the merger, the Company will no longer exist as an independent, publicly-traded company, and the Company’s stockholders will no longer be able to directly participate in any future earnings or growth of the Company or benefit from any appreciation in the Company’s value.

	•	Taxability of the Purchase Price . Gains from the all-cash merger generally will be taxable to the Company’s stockholders for U.S. federal income tax purposes.

The board of directors determined that the risks and negative factors were outweighed by the factors that supported the approval of the merger, and after considering all relevant factors (including those listed above), the board of directors unanimously approved the merger agreement and the merger.

This discussion of the information and factors that our board of directors considered is not intended to be exhaustive, but we believe this discussion includes all material factors considered by the board of directors. In view

of the wide variety of factors considered in connection with their respective evaluations of the merger and the complexity of these matters, our directors found it impracticable to, and did not, quantify or otherwise attempt to assign relative weight to the specific factors considered in reaching their determinations. Rather, each director made his or her judgment based on the total mix of information available to the board of directors of the overall effect of the merger on our stockholders compared to any alternative. The judgments of individual directors may have been influenced to a greater or lesser degree by their individual views with respect to different factors.

Based on the factors outlined above, the board of directors determined by unanimous vote:


	•	that the merger, the merger agreement and the transactions contemplated thereby are advisable and in the best interests of the Company and our stockholders;

	•	to approve the merger agreement; and

	•	to recommend to the Company’s stockholders that they vote “FOR” the adoption of the merger agreement and approval of the merger.

Opinion of Our Financial Advisor

Pursuant to an engagement letter dated April 7, 2008, EnergySouth retained JPMorgan as its financial advisor in connection with the proposed merger.

At the meeting of the board of directors of EnergySouth on July 25, 2008, JPMorgan rendered its oral opinion to the board of directors of EnergySouth that, as of such date and based upon and subject to the factors and assumptions set forth in its opinion, the consideration to be paid to EnergySouth’s common stockholders in the proposed merger was fair, from a financial point of view, to such stockholders. On July 25, 2008, JPMorgan confirmed its July 25, 2008 oral opinion in writing. No limitations were imposed by EnergySouth’s board of directors upon JPMorgan with respect to the investigations made or procedures followed by it in rendering its opinions.

The full text of the written opinion of JPMorgan dated July 25, 2008, which sets forth the assumptions made, matters considered and limits on the review undertaken, is attached as Annex B to this proxy statement and is incorporated herein by reference. EnergySouth’s stockholders are urged to read the opinion in its entirety. JPMorgan’s written opinion is addressed to the board of directors of EnergySouth, is directed only to the consideration to be paid in the merger and does not constitute a recommendation to any stockholder of EnergySouth as to how such stockholder should vote at the special meeting. The summary of the opinion of JPMorgan set forth in this proxy statement is qualified in its entirety by reference to the full text of such opinion.

In arriving at its opinions, JPMorgan, among other things:


	•	reviewed a draft dated July 21, 2008 of the merger agreement;

	•	reviewed certain publicly available business and financial information concerning EnergySouth and the industries in which it operates;

	•	compared the proposed financial terms of the merger with the publicly available financial terms of certain transactions involving companies JPMorgan deemed relevant and the consideration received for such companies;

	•	compared the financial and operating performance of EnergySouth with publicly available information concerning certain other companies JPMorgan deemed relevant and reviewed the current and historical market prices of EnergySouth common stock and certain publicly traded securities of such other companies;

	•	reviewed certain internal financial analyses and forecasts prepared by the management of EnergySouth relating to its business; and

	•	performed such other financial studies and analyses and considered such other information as JPMorgan deemed appropriate for the purposes of its opinion.

JPMorgan also held discussions with certain members of the management of EnergySouth and Sempra Energy with respect to certain aspects of the merger, the past and current business operations of EnergySouth, the financial condition and future prospects and operations of EnergySouth (including the views of senior management of EnergySouth with respect to the risks and uncertainties of the Company achieving its projections), and certain other matters JPMorgan believed necessary or appropriate to its inquiry.

JPMorgan relied upon and assumed, without assuming responsibility or liability for independent verification, the accuracy and completeness of all information that was publicly available or was furnished to or discussed with JPMorgan by EnergySouth or otherwise reviewed by or for JPMorgan. JPMorgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities, nor did JPMorgan evaluate the solvency of EnergySouth or Sempra Energy under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to it, JPMorgan assumed that they were reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of EnergySouth to which such analyses or forecasts relate. JPMorgan expressed no view as to such analyses or forecasts or the assumptions on which they were based. JPMorgan also assumed that the merger and the other transactions contemplated by the merger agreement will be consummated as described in the merger agreement and that the definitive merger agreement would not differ in any material respect from the draft thereof provided to JPMorgan on July 21, 2008. JPMorgan relied as to all legal matters relevant to the rendering of its opinion upon the advice of counsel. JPMorgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on EnergySouth or on the contemplated benefits of the merger.

The projections furnished to JPMorgan for EnergySouth were prepared by the management of EnergySouth. EnergySouth does not publicly disclose internal management projections of the type provided to JPMorgan in connection with JPMorgan’s analysis of the merger, and such projections were not prepared with a view toward public disclosure. These projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of management, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections.

JPMorgan’s opinion is based on economic, market and other conditions as in effect on, and the information made available to JPMorgan as of, the date of such opinion. Subsequent developments may affect JPMorgan’s written opinion dated July 25, 2008, and JPMorgan does not have any obligation to update, revise, or reaffirm such opinion. JPMorgan’s opinion is limited to the fairness, from a financial point of view, of the consideration to be paid to EnergySouth’s common stockholders in the proposed merger, and JPMorgan has expressed no opinion as to the fairness of the merger to, or any consideration of, the holders of any other class of securities, creditors or other constituencies of EnergySouth or the underlying decision by EnergySouth to engage in the merger. JPMorgan expressed no opinion as to the price at which the Company’s common stock will trade at any future time, whether before or after the merger.

In accordance with customary investment banking practice, JPMorgan employed generally accepted valuation methods in reaching its opinion. The following is a summary of the material financial analyses utilized by JPMorgan in connection with providing its opinion.

Public Trading Multiples . Using publicly available information, JPMorgan compared selected financial data of EnergySouth with similar data for selected publicly traded companies engaged in businesses which JPMorgan judged to be similar to those of EnergySouth. The companies selected by JPMorgan and viewed as relevant to EnergySouth’s natural gas midstream business were El Paso, Enbridge, Southern Union, Spectra Energy, TransCanada and Williams. The companies selected by JPMorgan and viewed as relevant to EnergySouth’s natural gas distribution business were AGL Resources, Atmos Energy, Laclede Group, New Jersey Resources, Nicor, Northwest Natural Gas, Piedmont Natural Gas, South Jersey Industries, Southwest Gas and WGL Holdings.

These companies were selected, among other reasons, because they share similar business characteristics to EnergySouth based on operational characteristics and financial metrics, as well as their significant exposure to the midstream and natural gas utility industry in the United States. However, none of the companies selected is identical or directly comparable to EnergySouth. Accordingly, JPMorgan made judgments and assumptions concerning

differences in financial and operating characteristics of the selected companies and other factors that could affect the public trading value of the selected companies.

For each of the selected companies, JPMorgan calculated Firm Value divided by the estimated earnings before interest, taxes, depreciation and amortization, or EBITDA, for the calendar years ending December 31, 2008 and 2009, which are referred to as Firm Value/EBITDA Multiples, as well as the stock price of common equity divided by the earnings per share, or EPS, for the same periods, which are referred to as Price/Earnings Multiples.

For this analysis, Firm Value of a particular company was calculated as market value of that company’s common stock based on fully diluted shares using the treasury method (as of July 21, 2008) plus the value of that company’s indebtedness, minority interest and preferred stock, minus that company’s cash and cash equivalents and marketable securities.

The following table reflects the ratios, Firm Value and public market multiples for each of the selected companies reviewed by JPMorgan:

Based on the results of this analysis and on JPMorgan’s judgment and experience, JPMorgan applied Price/Earnings Multiples ranging from 13.0x to 17.0x for calendar year 2008 EPS and 12.5x to 16.5x for calendar year 2009 EPS to EnergySouth’s natural gas midstream and natural gas distribution segments, which, using EnergySouth’s estimated EPS for such periods, implied ranges for EnergySouth’s common stock of $31.25 to $40.60 and $41.60 to $54.45 per share, respectively.

Further, JPMorgan applied ranges of 7.5x to 9.5x and 6.5x to 8.0x Firm Value/EBITDA Multiples to EnergySouth’s natural gas midstream and natural gas distribution segments, which, using EnergySouth’s estimates for calendar year 2008 EBITDA, implied a range for EnergySouth’s common stock of $9.40 to $20.25 per share.

Additionally, JPMorgan applied ranges of 7.0x to 9.0x and 6.0x to 7.5x Firm Value/EBITDA Multiples to EnergySouth’s natural gas midstream and natural gas distribution segments, respectively, using EnergySouth’s estimates for calendar year 2012 EBITDA. The resulting values were then adjusted for EnergySouth’s estimated calendar year 2010 year-end excess cash, total debt and minority interest and subsequently discounted back to present values, implying a range for EnergySouth’s common stock of $30.95 to $60.25 per share.

(1)		Terminated.

For each of the selected transactions, JPMorgan calculated the transaction value divided by the latest 12 months EBITDA, or LTM EBITDA, which ratio is referred to as Transaction Value/LTM EBITDA Multiple.

Based on the results of this analysis, JPMorgan applied ranges of 9.0x to 11.5x and 8.5x to 10.0x Transaction Value/LTM EBITDA Multiples to the natural gas midstream and natural gas distribution segments’ fiscal year 2012 projected EBITDA, respectively. The resulting values were then adjusted for EnergySouth’s estimated 2012 fiscal year-end excess cash, total debt and minority interest and subsequently discounted back to present values, implying a range for EnergySouth’s common stock of $49.45 to $78.40 per share, based on fully diluted shares using the treasury method.

Discounted Cash Flow Analysis . JPMorgan conducted a discounted cash flow analysis for the purpose of determining the fully diluted equity value per share for EnergySouth’s common stock. JPMorgan calculated the unlevered free cash flows that EnergySouth is expected to generate during fiscal years 2009 through 2018 based upon financial projections prepared by the management of EnergySouth through the years ended September 30th. JPMorgan also calculated a range of terminal asset values of EnergySouth at the end of the 10-year period by applying perpetual growth rates ranging from 2.0% to 3.0% and 1.0% to 1.5% of the unlevered free cash flow of the natural gas midstream and natural gas distribution segments of EnergySouth, respectively, during the final year of the 10-year period. The unlevered free cash flows and the range of terminal asset values were then discounted to present values using a range of discount rates from 9.0% to 10.0% and 6.5% to 7.5% for EnergySouth’s natural gas midstream and natural gas distribution segments, respectively, which were chosen by JPMorgan based upon an analysis of the weighted average cost of capital of EnergySouth’s two business segments. The present value of the unlevered free cash flows and the range of terminal asset values were then adjusted for EnergySouth’s estimated 2008 fiscal year-end excess cash and total debt. Based on the management projections, the chosen discount rate range and fully diluted shares using the treasury method, the discounted cash flow analysis indicated a range of equity values of between $46.50 and $80.05 per share of EnergySouth’s common stock and a midpoint of $60.95 per share of EnergySouth’s common stock. EnergySouth management further provided JPMorgan with two sensitivity cases for management’s base financial projections, reflecting some of the risks and uncertainties of achieving management’s base financial projections. The two sensitivity cases were reflective of (i) delays in storage cavern in-service dates and increased gas prices and (ii) delays in storage cavern in-service dates, as well as increased gas prices and capital expenditures over the projection period. Based on the same discount rate and perpetual growth rate ranges detailed above and fully diluted shares using the treasury method, the discounted cash flow analysis indicated ranges of equity values of between $42.10 and $75.35, and $36.25 and $69.40, with midpoints of $56.41 and $50.50 per share of EnergySouth’s common stock for the two sensitivity cases, respectively.

Other Information . JPMorgan also reviewed the 52-week, 3-month and 1-month trading ranges of EnergySouth’s common stock. JPMorgan noted that historical stock trading is not a valuation methodology but was presented merely for informational purposes.

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by JPMorgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. JPMorgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. In arriving at its opinion, JPMorgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, JPMorgan considered the totality of the factors and analyses performed in determining its opinion. Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by JPMorgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, JPMorgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold. None of the selected companies reviewed as described in the above summary is identical to EnergySouth, and none of the selected transactions reviewed was identical to the merger. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of JPMorgan’s analysis, may be considered similar to those of

EnergySouth. The transactions selected were similarly chosen because their participants, size and other factors, for purposes of JPMorgan’s analysis, may be considered similar to the merger. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to EnergySouth and the transactions compared to the merger.

As a part of its investment banking business, JPMorgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, and valuations for estate, corporate and other purposes. JPMorgan was selected to advise EnergySouth with respect to the merger on the basis of such experience and its familiarity with EnergySouth.

For services rendered in connection with the merger, EnergySouth has paid JPMorgan a fee of $1.5 million upon delivery of its written fairness opinion and will pay JPMorgan a fee in the amount of approximately $3.6 million upon consummation of the merger. In addition, EnergySouth has agreed to reimburse JPMorgan for its expenses incurred in connection with its services, including the fees and disbursements of counsel, and will indemnify JPMorgan against certain liabilities, including liabilities arising under the Federal securities laws. If EnergySouth receives a termination fee from Sempra Energy or from any other source as a result of the merger or any other transaction not being consummated, EnergySouth must pay JPMorgan 12.5% of such fee, which fee will not exceed the transaction fee that would have been payable to JPMorgan had the merger closed, and which fee will be reduced by the $1.5 million fee paid upon delivery of JPMorgan’s opinion. In addition, JPMorgan will be entitled to fees for any transaction involving the acquisition of EnergySouth consummated during the term of its engagement or 12 months after its expiration or termination. The engagement runs for 18 months from the effective date of the engagement letter, which is March 19, 2008.

JPMorgan and its affiliates have performed in the past, and may continue to perform, certain financial advisory, financing and other investment banking and commercial banking services for EnergySouth, Sempra Energy and one or more of their affiliates. During the two years preceding the date of its opinion, JPMorgan and its affiliates had commercial or investment banking relationships with EnergySouth and Sempra Energy, for which it and such affiliates received customary compensation. Such services during such period included acting as (1) lead manager for an offering of $55,000,000 in principal amount of Industrial Revenue Development Bonds in August 2007, the proceeds of which were loaned to a subsidiary of EnergySouth; (2) joint book-running manager for Sempra Energy’s offering of $500,000,000 in principal amount of notes in June 2008; (3) seller in a $161,000,000 share repurchase program by Sempra Energy of its common stock that concluded in September 2007; (4) lead manager and current remarketing agent for the offering of $161,000,000 in principal amount of Industrial Development Revenue Refunding Bonds by a subsidiary of Sempra Energy beginning in September 2006; and (5) commercial paper dealer for a $2,000,000,000 revolving commercial paper program issued by a joint venture in which Sempra Energy holds a minority interest beginning in June 2006. In addition, JPMorgan’s commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of EnergySouth and Sempra Energy, for which it receives customary fees. In the ordinary course of their businesses, JPMorgan and its affiliates may actively trade the debt and equity securities of EnergySouth or Sempra Energy for their own accounts or for the accounts of customers and, accordingly, they may at any time hold long or short positions in such securities.

Interests of Certain Persons in the Merger

When considering the recommendation of our board of directors, you should be aware that our executive officers and members of our board of directors have interests in the merger other than their interests as EnergySouth stockholders generally, pursuant to agreements between such executive officers and directors and us and pursuant to the merger agreement. These interests may be different from, or in conflict with, your interests as EnergySouth stockholders. The members of our board of directors were aware of these additional interests, and considered them, when they approved the merger agreement.

Change of Control and Employment Agreements

We have entered into an employment agreement with each of Messrs. C. S. “Dean” Liollio and Benjamin J. Reese and a change of control agreement with each of Messrs. G. Edgar Downing, Jr., Charles P. Huffman, Gregory H. Welch

and other employees who are not executive officers. These employment agreements and change of control agreements provide for payments and benefits to the executive upon the termination of the executive’s employment following a change of control, as described below.

If the executive’s employment is terminated by the surviving corporation for any reason other than cause, or by the executive for good reason, within 24 months following the merger, he will receive a severance amount. In the case of Mr. Liollio, this severance amount is equal to three times the sum of his then-current base salary plus his annual bonus target for the performance year in which his termination occurs. In the case of Mr. Reese, this severance amount is equal to the sum of three times his then-current base salary plus (1) if the termination occurs following the determination of his individual performance award in 2008 but prior to the determination of his individual performance award in 2009, three times the amount of his individual performance award for 2008, or (2) if the termination occurs following the determination of his individual performance award in 2009, three times the average amount of his individual performance award for the most recent two years. In the case of Mr. Downing, this severance amount is equal to two times the sum of his then-current base salary plus his annual bonus target for the performance year in which his termination occurs. In the case of Messrs. Huffman and Welch, this severance amount is equal to 2.97 times the sum of his then-current base salary plus his annual bonus target for the performance year in which his termination occurs.

In addition to Mr. Liollio’s severance amount, if he is terminated for any reason other than cause, or by him for good reason, within 24 months following the merger, he would be entitled to receive any unpaid restoration compensation credit and cash performance award under his employment agreement. The unpaid restoration compensation credit equals $250,000, which otherwise would be payable on August 1, 2009. The unpaid cash performance award is an amount up to $500,000, equal to $250,000 times a fraction, the denominator of which is our average trading price over the five trading days prior to August 1, 2006 and the numerator of which is $61.50.

In addition to the severance amounts, in the case of each of Messrs. Liollio, Huffman and Welch, we, or the surviving corporation, as the case may be, will also continue the executive’s medical and life insurance coverage until the earlier of the three year anniversary of the termination or the executive’s re-employment with another employer. In the case of Mr. Downing, medical and life insurance coverage will continue until the earlier of the two year anniversary of his termination or his re-employment with another employer.

Executive Officers’ Stock Options

Our executive officers as a group hold “in the money” options to purchase 249,155 shares of our common stock as of August 8, 2008, having a weighed average exercise price of $32.30. Each outstanding option (whether vested or unvested) will be cancelled at the effective time of the merger in exchange for a cash payment, without interest, equal to the product of (1) the number of shares of EnergySouth common stock subject to such option, multiplied by (2) the amount by which $61.50 exceeds the option exercise price per share of common stock subject to such option, less any required withholding taxes. Accordingly, executive officers and non-employee directors with unvested “in the money” options may receive a benefit, in addition to that available to EnergySouth stockholders generally, by virtue of the acceleration of the unvested portion of such options. See “The Merger Agreement — Treatment of Stock Options, Performance Shares, Performance-Based Restricted Stock Units and Phantom Stock Units” on page .

The value attributable to the cancellation and cash-out in connection with merger of all stock options held by our executive officers is approximately $7.3 million, as follows:


	Shares of Common Stock				Net Value of all
	Subject to Options				Options Held by
			Vesting Accelerated		Executive Officer

Total		249,155		115,455	$	7,274,536


(1)		Net value of options determined as $61.50 minus the option exercise price multiplied by the number of shares subject to the option.

Executive Officers’ Performance Share Awards and Performance-Based Restricted Stock Unit Awards

Our executive officers as a group hold performance share awards and performance-based restricted stock unit awards with respect to an aggregate of 24,070 shares underlying such awards (at the target award level). Each performance share award and performance-based restricted stock unit award outstanding immediately prior to the effective time of the merger will be cancelled and the holder of such award will be entitled to receive from the surviving corporation an amount of cash, without interest, equal to the product of (1) the target number of shares underlying such award, multiplied by (2) the per share merger consideration of $61.50, less the amount of any required tax withholding. See “The Merger Agreement — Treatment of Stock Options, Performance Shares, Performance-Based Restricted Stock Units and Phantom Stock Units” on page .

The value attributable to the performance share awards and performance-based restricted stock unit awards held by our executive officers is approximately $1.5 million, as follows:


	Shares Underlying
	Performance Share Awards and Performance-
	Based Restricted Stock Unit				Value of Shares
	Awards		Vesting Accelerated		Vested
Officer	Total		Upon Merger		Upon Merger(1)

C.S. “Dean” Liollio		17,960		17,960	$	1,104,540

Total		24,070		24,070	$	1,480,305


(1)		Value of shares determined as $61.50 multiplied by the number of shares that would be unvested (still subject to forfeiture) immediately prior to the effective date.

Executive Officers’ Incentive Compensation Awards

If the effective time of the merger occurs prior to November 15, 2008, then immediately prior to the effective time, we will pay to each executive officer then actively employed by us or one of our subsidiaries any amounts due under outstanding awards granted under our executive incentive compensation plan, as applicable, with respect to the full fiscal year ending on September 30, 2008. However, the amount of each such payment will be determined by the compensation committee of our board of directors with regard to executives based on their available financial information in a manner reasonably consistent with the intent of the applicable compensation plan; provided that the aggregate payments under both our executive incentive compensation plan and employee incentive compensation plan must not exceed $4,800,000. However, this cap of $4,800,000 is exclusive of the bonus pool funding the team performance awards that are payable under the employment agreements with Messrs. Reese, Brown, and Pirraglia, which will be paid in accordance with the terms under their respective employment agreements.

If the effective time of the merger occurs on or after November 15, 2008, then immediately prior to the effective time, we will pay to each executive officer then actively employed by us or one of our subsidiaries any amounts due under the terms and conditions of such award and the executive incentive compensation plan for the full fiscal year ending September 30, 2008; provided that the aggregate payments under both our executive incentive compensation plan and employee incentive compensation plan must not exceed $4,800,000. See “The Merger Agreement — Treatment of Employee Compensation Plans” on page .

Non-Employee Directors’ Phantom Stock Units

Our non-employee directors as a group hold 59,119 phantom stock units. At the effective time of the merger, the phantom stock units credited to each participating director’s account under the Second Amended and Restated EnergySouth, Inc. Non-Employee Directors Deferred Fee Plan and/or the 2005 Non-Employee Directors Deferred Fee Plan will be converted into a dollar amount equal to the product of (1) the number of phantom stock units credited to such participant’s account, multiplied by (2) the per share merger consideration of $61.50, rounded to the nearest cent. Such dollar amount will be credited to the participant’s cash account under the applicable plan, and the phantom stock units shall be debited from such participant’s plan account. Following the effective time of the merger, each participant’s plan account will be credited with interest when and as provided in the applicable plan. Under the Second Amended and Restated EnergySouth, Inc. Non-Employee Directors Deferred Fee Plan, balances in such accounts will be distributed in cash upon the completion of the merger if the participant elected such distribution under his or her distribution election. Under the 2005 Non-Employee Directors Deferred Fee Plan, participants will automatically receive a lump sum cash distribution of their account balances upon completion of the merger. The Company has amended these plans to provide that, as of the effective time of the merger, no further phantom stock units will be credited to the participants’ accounts and account balances will be distributed only in cash.

The value attributable to the phantom stock units held by our non-employee directors is approximately $3.6 million, as follows:


	Phantom Stock Units				Value of Units
			Vesting Accelerated		Converted
Non-Employee Director	Total		Upon Merger		Upon Merger(1)

John C. Hope		21,888		21,888	$	1,346,112

(1)		Value of units determined as $61.50 multiplied by the number of phantom stock units outstanding immediately prior to the effective date.

Post Merger Arrangements

The merger agreement provides that the officers of the Company immediately prior to the consummation of the merger will be the initial officers of the corporation surviving the merger, until the earlier of their resignation or removal.

As of the date of this proxy statement, none of our executive officers has entered into any amendments or modifications to their existing severance agreements with us in connection with the merger. In addition, as of the date of this proxy statement, none of our executive officers has entered into any agreement, arrangement or understanding with Sempra Energy or any of its affiliates regarding the terms and conditions of compensation, cash-based incentives, or employment with the surviving corporation. We have been informed that Sempra Energy anticipates that it will, prior to the effective time of the merger, initiate discussions with members of our existing executive team relating to the terms and conditions of new agreements and amendments to existing severance agreements, so as to encourage their retention with the surviving corporation after the effective time of the merger. Although we believe members of our existing executive team are likely to enter into new agreements and agree to amendments to existing severance agreements prior to the completion of the merger and may participate in equity compensation plans of Sempra Energy after consummation of the merger, such matters are subject to further negotiations and discussion and no terms or conditions have been finalized.

Indemnification and Insurance

The merger agreement provides that after the effective time of the merger, Sempra Energy and the surviving corporation will indemnify and hold harmless the current and former directors and officers of EnergySouth and its subsidiaries for actions or omissions, occurring at or prior to the effective time of the merger, to the fullest extent permitted by law or as provided in our certificate of incorporation, bylaws, the organizational documents of any of our subsidiaries or any written indemnification contract between such directors or officers and us. Further, for six years following the effective time of the merger, the certificate of incorporation and bylaws of the surviving corporation will contain indemnification, advancement of expenses and exculpation provisions for acts or omissions occurring at or prior to the effective time of the merger that are no less favorable to our current and former directors and officers than those that are presently set forth in our certificate of incorporation or bylaws.

In addition, the merger agreement provides that prior to the effective time of the merger, we will use commercially reasonable efforts to purchase a six-year “tail” prepaid policy on our directors’ and officers’ liability insurance policy on terms no less favorable to our directors and officers than those of our current policy. If, however, we cannot or do not purchase such a “tail” policy, then Sempra Energy or the surviving corporation will purchase the tail policy promptly after the effective time. If, nevertheless, we, Sempra Energy and the surviving corporation all fail to obtain such a “tail” policy, Sempra Energy will, or will cause the surviving corporation to, maintain our current directors’ and officers’ liability insurance for acts or omissions occurring at or prior to the effective time of the merger. Sempra Energy may satisfy this obligation by (1) substituting its own policies containing terms no less favorable to such directors and officers or (2) requesting that the surviving corporation obtain such extended coverage under its existing insurance programs. If such insurance is unavailable, the surviving corporation will, and Sempra Energy will cause the surviving corporation to, purchase the best available coverage for such six-year period from an insurance carrier with the same or better credit rating as our current insurance carrier on terms at least as favorable as provided in our existing policies. Sempra Energy and the surviving corporation are not obligated to pay an amount that is more than 300% of our current annual premium for such insurance to procure the required coverage. If Sempra Energy and the surviving corporation cannot obtain the required coverage for that amount, the surviving corporation must provide the most coverage that can be obtained for that amount.

Material U.S. Federal Income Tax Considerations

The following discussion summarizes the material United States federal income tax consequences of the merger that are generally applicable to holders of our common stock. This discussion is based on currently existing provisions of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, existing and proposed U.S. Treasury regulations promulgated under the Code, and current administrative rulings and court decisions, all of

which are subject to change. Any change, which may or may not be retroactive, could alter the tax consequences of the merger to the holders of our common stock.

The following discussion does not address the tax consequences that may be relevant to stockholders who receive special treatment under some U.S. federal income tax laws. Stockholders receiving this special treatment include but are not limited to:


	•	financial institutions, insurance companies, tax-exempt organizations, “S” corporations, partnerships, mutual funds, dealers in securities or foreign currencies or traders in securities that elect a mark-to-market method of tax accounting;

	•	taxpayers who hold shares of our common stock as part of a “straddle,” a “hedge” or a “conversion transaction” as those terms are defined under the Code; and

	•	stockholders who acquired their shares of common stock through the exercise of employee or director stock options, as restricted shares or otherwise as compensation.

Further, we do not address:


	•	the U.S. federal income tax consequences to partnerships or other pass-through entities and partners or other investors in such entities;

	•	the U.S. federal estate and gift or alternative minimum tax consequences of the purchase, ownership or sale of shares of our common stock; or

	•	any local, state or foreign tax consequences of the purchase, ownership and sale of the shares.

For purposes of this summary, a U.S. Holder is a person that is a beneficial owner of our common stock and is:


	•	a citizen or resident of the U.S.;

	•	a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the U.S., any state or any political subdivision thereof;

	•	a trust if (1) a U.S. court can exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or (2) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or

	•	an estate, the income of which is subject to U.S. federal income taxation regardless of its source.

A Non-U.S. Holder is a person that is a beneficial owner of our common stock other than a U.S. Holder.

No rulings have been sought or will be sought from the U.S. Internal Revenue Service, which we refer to as the IRS, with respect to any of the U.S. federal income tax considerations discussed below. As a result, we cannot assure you that the IRS will agree with the tax characterizations and the tax consequences described below.

You should consult your own tax advisor concerning the U.S. federal income and estate tax consequences in light of your particular situation and any consequences arising under the laws of any other taxing jurisdiction.

Treatment of U.S. Holders

U.S. Holders who receive cash for their shares will recognize gain or loss for federal income tax purposes equal to the difference between the amount of cash received and the tax basis of the shares exchanged in the merger. If a U.S. Holder holds shares of our common stock as a capital asset, the gain or loss will be capital gain or loss. Any capital gain or loss will be long-term capital gain or loss if the stockholder’s holding period for the shares is more than one year. Long-term capital gain of an individual is generally subject to a maximum U.S. federal income tax rate of 15%. The deductibility of long-term capital losses is subject to limitations.

Treatment of Non-U.S. Holders

The following is a summary of U.S. federal tax consequences that will apply to you if you are a Non-U.S. Holder of shares of our common stock. As described above, a “Non-U.S. Holder” is a person that is a beneficial owner of our common stock other than a U.S. Holder.

Special rules may apply to certain Non-U.S. Holders such as “controlled foreign corporations,” “passive foreign investment companies,” corporations that accumulate earnings to avoid federal income tax or, in certain circumstances, individuals who are U.S. expatriates. The discussion below does not apply to such special circumstances. Such Non-U.S. Holders should consult their own tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them.

Any gain that a Non-U.S. Holder realizes upon the sale, exchange, redemption or other disposition of a share of our common stock generally will not be subject to U.S. federal income tax unless:


	•	that gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the U.S. or, where a tax treaty applies, is attributable to a U.S. permanent establishment;

	•	the Non-U.S. Holder is an individual who is present in the U.S. for 183 or more days in the taxable year of that disposition and certain other conditions are met; or

	•	we are or have been a U.S. real property holding corporation for U.S. federal income tax purposes, our stock is traded on an established securities market, and the Non-U.S. Holder’s beneficial and constructive ownership of our common stock exceeds 5% of the total fair market value of our common stock.

A Non-U.S. Holder who realizes gain described in the first and third bullet points above will be subject to U.S. federal income tax on the net gain derived. An individual Non-U.S. Holder described in the second bullet point above will be subject to a flat 30% U.S. federal income tax on the gain derived, which may be offset by U.S. source capital losses, even though the holder is not considered a resident of the U.S. A Non-U.S. Holder that is a foreign corporation and that realizes gain described in the first and third bullet points above will be subject to tax on the gain at regular graduated U.S. federal income tax rates and, in addition, may be subject to a “branch profits tax” at a 30% rate or a lower rate if so specified by an applicable income tax treaty.

Backup Withholding and Information Reporting

If you are a U.S. Holder of our common stock, information reporting requirements will generally apply to the cash proceeds you receive from the sale of your common stock in the merger, unless you are an exempt recipient such as a corporation. If you are not otherwise exempt and you fail to supply your correct taxpayer identification number, under-report your tax liability or otherwise fail to comply with applicable U.S. information reporting or certification requirements, the IRS may require us to withhold federal income tax from those proceeds at the rate set by Section 3406 of the Code.

In general, if you are a Non-U.S. Holder, you will not be subject to backup withholding and information reporting with respect to the cash proceeds paid to you in the merger, provided that we do not have actual knowledge or reason to know that you are a U.S. person, as defined under the Code, and you have given us a certification, under penalty of perjury, that you are not a U.S. person (which certification may be made on an IRS Form W-8BEN (or successor form)) and provide your name, address and certain other required information or certain other certification requirements or, if you hold your shares through certain qualified intermediaries, you satisfy the certification requirements of applicable U.S. Treasury regulations (special certification rules apply to holders that are pass-through entities).

Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished by you to the IRS.

Merger Sub is not engaged in any business except as contemplated by the merger agreement. Merger Sub’s principal office address is c/o Sempra Energy, 101 Ash Street, San Diego, California 92101, and its telephone number is (619) 696-2034.

THE MERGER AGREEMENT

The following is a summary of the material terms of the merger agreement but does not describe all of the terms of the merger agreement. This summary is qualified in its entirety by reference to the merger agreement, which is attached as Annex A to this proxy statement and incorporated herein by reference. You are urged to read the merger agreement in its entirety because it is the legal document that governs the merger.

The description of the merger agreement has been included to provide you with information regarding its terms. It is not intended to provide any other factual information about us. Such information can be found elsewhere in this proxy statement and in the other public filings EnergySouth makes with the SEC, which are available without charge at www.sec.gov.

The merger agreement contains representations and warranties that we, Sempra Energy and Merger Sub have made to each other as of the date of the merger agreement or other specific dates. The assertions embodied in those representations and warranties were made solely for the purposes of the contract between us, Sempra Energy and Merger Sub. Additionally, information concerning the subject matter of the representations and warranties may

have changed since the date of the merger agreement, which subsequent information may or may not be fully reflected in EnergySouth’s public disclosures. Moreover, certain representations and warranties may not be complete or accurate because they are subject to a contractual standard of materiality different from that generally applicable to stockholders and were used for the purpose of allocating risk between us and Sempra Energy and Merger Sub rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts at the time they were made or otherwise.

The Merger

The merger agreement provides that, upon and subject to the terms and conditions of the merger agreement, and in accordance with the applicable provisions of the Delaware General Corporation Law, or the DGCL, Merger Sub will be merged with and into EnergySouth. At that time, Merger Sub’s separate existence will cease and we will continue as the surviving corporation. Following the merger, we will be a privately-held corporation and a wholly-owned indirect subsidiary of Sempra Energy. The merger will become effective at the time the certificate of merger is filed with the Secretary of State of the State of Delaware or at such later time as Sempra Energy and we shall agree and specify in the certificate of merger. The certificate of merger will be filed on the closing date, which is expected to occur within three business days after all conditions specified in the merger agreement have been satisfied or waived.

Upon the effective time of the merger, you will cease to have any ownership interests in EnergySouth or rights as one of our stockholders. Accordingly, you will not participate in any future earnings or growth of EnergySouth and will not benefit from any appreciation in the value of our business. Instead, your shares of our common stock will be converted into and exchanged for the right to receive $61.50 per share in cash, without interest, less any applicable withholding taxes, as more fully described below.

Our common stock is currently listed on the Nasdaq Global Select Market under the symbol “ENSI.” After the merger, our common stock will cease to be listed on Nasdaq and there will be no public market for our common stock. Our common stock is also registered with the SEC under the Exchange Act. Following the merger, we expect to deregister our shares of common stock and cease to be a public reporting company. Accordingly, we will no longer be required to file periodic and current reports, such as annual, quarterly and current reports on Forms 10-K, 10-Q and 8-K, with the SEC.

At the effective time of the merger, our certificate of incorporation and bylaws will be replaced with the certificate of incorporation and bylaws of Merger Sub. Also, at the effective time of the merger, the directors of Merger Sub in office immediately prior to the effective time of the merger will become the directors of EnergySouth. The officers of EnergySouth immediately prior to the effective time of the merger shall continue to serve as officers of EnergySouth in accordance with the new bylaws.

Merger Consideration

Upon consummation of the merger, each share of our common stock issued and outstanding at the effective time of the merger (other than shares held by stockholders who perfect their statutory appraisal rights and shares held by us or Sempra Energy or our respective subsidiaries) will cease to be outstanding and will be converted into and exchanged for the right to receive $61.50 in cash, without interest, less any applicable withholding taxes. Each share of our common stock owned by us, Sempra Energy or Merger Sub will be cancelled and cease to exist with no consideration issued in exchange for these shares. Each share of our common stock owned by a wholly-owned subsidiary of us or Sempra Energy (other than Merger Sub) will remain outstanding and will be appropriately adjusted so that each subsidiary will continue to own the same percentage of us after the merger as it owned beforehand. Each issued and outstanding share of capital stock of Merger Sub will be converted into and become one share of common stock of the surviving corporation.

Procedures for Exchange of Certificates

Prior to the effective time of the merger, Sempra Energy will deposit with an exchange agent, for the benefit of the holders of our common stock, cash in an amount sufficient to pay the aggregate merger consideration, which we refer to as the exchange fund. Promptly, and in any event within five business days, after the effective time of the

merger, the exchange agent will send transmittal materials and instructions to each stockholder of record of EnergySouth whose shares of our common stock were converted into and exchanged for the right to receive the merger consideration discussed above. The transmittal materials will contain instructions for obtaining cash in exchange for shares of our common stock. Upon surrender of a stock certificate that formerly represented shares of our common stock, or the transfer of uncertificated shares of our common stock, together with a duly executed letter of transmittal and such other documents as the exchange agent may reasonably require in connection with its duties, the stockholder will be entitled to receive from the exchange agent, on behalf of EnergySouth, $61.50 in cash for each share represented by a stock certificate and each uncertificated share, without interest and less any applicable withholding taxes.

In the event of a transfer of ownership of shares of our common stock that is not registered in our stock transfer books, the merger consideration for those shares may be paid to a person other than the person in whose name those shares are registered if the certificate representing those shares is delivered to the exchange agent, accompanied by all documents required to evidence such transfer and by evidence satisfactory to the exchange agent that any applicable stock transfer taxes have been paid. No interest will be paid or accrue on any cash payable upon the surrender of stock certificates representing shares of our common stock or the transfer of uncertificated shares of our common stock. A stockholder whose stock certificate has been lost, stolen or destroyed may obtain the merger consideration payable with respect to the shares of common stock represented by the certificate by submitting an affidavit of loss, posting such bond as Sempra Energy or the exchange agent may reasonably require, submitting any other documents necessary to evidence and effect the bona fide exchange thereof, and complying with any other reasonable and customary rules and procedures that the exchange agent may require in connection with its duties.

At any time following one year after the effective time of the merger, Sempra Energy will be entitled to require the exchange agent to deliver to Sempra Energy any funds remaining in the exchange fund which have not been disbursed to stockholders as of such time, and thereafter, such stockholders are only entitled to look to Sempra Energy as general creditors thereof with respect to the payment of the merger consideration. Such stockholders will have no greater rights against Sempra Energy than may be accorded to general creditors of Sempra Energy under applicable laws. None of Sempra Energy, Merger Sub, EnergySouth or the exchange agent will be liable to any person in respect of any funds from the exchange fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar laws.

Treatment of Stock Options, Performance Shares, Performance-Based Restricted Stock Units and Phantom Stock Units

Upon consummation of the merger, all outstanding stock options, performance share awards and performance-based restricted stock unit awards will be cancelled and exchanged for a cash payment. The cash payment for each share of stock subject to a stock option will be equal to the amount, if any, by which the merger consideration of $61.50 exceeds the per share exercise price of such option. The cash payment for each performance share award or performance-based restricted stock unit award will be equal to the target number of shares or units underlying such award multiplied by the merger consideration of $61.50. In each case, the aggregate amount of such payment to the holder will be rounded to the nearest cent, paid without interest, and reduced by any applicable withholding taxes.

Upon consummation of the merger, each phantom stock unit credited to the accounts of our non-employee directors under certain of our deferred fee plans will be converted into a dollar amount equal to the merger consideration of $61.50, rounded to the nearest cent. The dollar amount will be credited to the participant’s cash account under the applicable deferred fee plan, and the phantom stock units will be debited from such participant’s account. Our deferred fee plans have been amended to provide that as of the effective time no further phantom stock units will be credited to participants’ accounts and account balances may be distributed only in cash.

Treatment of Employee Compensation Plans

Should the effective time of the merger occur prior to November 15, 2008, then immediately prior to the effective time we will pay to each employee then actively employed by us or one of our subsidiaries any amounts due under outstanding awards granted under our executive incentive compensation plan or employee incentive compensation plan, as applicable, 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 applicable compensation plan, as determined by the compensation committee of our board of directors with regard to executives and by our president and chief executive officer with regard to our other employees; provided that the aggregate amount of such payments under both such plans shall not exceed $4,800,000.

Should the effective time of the merger occur on or after November 15, 2008, then immediately prior to the effective time we will pay to each employee then actively employed by us or one or our subsidiaries any amounts due under the terms and conditions of such award and the applicable 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.

	•	the accuracy of the information contained in this proxy statement and its compliance with law.

The merger agreement also contains representations and warranties that Sempra Energy and Merger Sub made to us. These relate to, among other things:


	•	their corporate existence, good standing, qualification and authority;

	•	their organizational documents;

	•	their authority to enter into the merger agreement and to consummate the merger;

	•	the absence of conflicts with or breaches of their organizational documents, applicable law, or under certain agreements to which they are a party;

	•	the required consents and authorizations of governmental authorities;

	•	the absence of any pending or threatened litigation against Sempra Energy or its subsidiaries which would have a material adverse affect on the ability of Sempra Energy or its subsidiaries to consummate the merger;

	•	the existence of sufficient funds to pay the merger consideration; and

	•	the accuracy of the information Sempra Energy or Merger Sub provided to us for inclusion in this proxy statement.

Many of the representations and warranties made by each party in the merger agreement are qualified by a “material adverse effect” standard. This standard requires the representations and warranties to which it applies to be true except in the cases where their failure to be true would not have a “material adverse effect.” The merger agreement defines the term “material adverse effect,” with respect to us, to mean any change, effect, event, occurrence, state of facts or development that, individually or in the aggregate, is or would reasonably be expected (1) to prevent, materially delay or materially impede our ability to consummate the merger or other transactions contemplated by the merger agreement, or (2) to be materially adverse to the business, condition (financial or

otherwise), assets, liabilities or results of operations of us or our subsidiaries, taken as a whole. However, this definition of “material adverse effect” excludes:


	•	changes in financial or securities markets or the economy or political conditions in the United States generally that do not disproportionately affect us and our subsidiaries as a whole;

	•	changes affecting the industries in which we or any of our subsidiaries operate (including changes in the price of natural gas) that do not disproportionately affect us and our subsidiaries as a whole;

	•	changes in the trading price of our common stock (except that the underlying fact or development that caused or contributed to such change may constitute a material adverse effect);

	•	changes resulting from natural disasters or any outbreaks of major hostilities or acts of war or terrorism involving the United States;

	•	our failure to meet internal or third party projections, forecasts, budgets or any published revenue or earnings projections for any period ending on or after the date of the merger agreement (except that the underlying fact or development that caused or contributed to such failure may constitute a material adverse effect);

	•	actions required to be taken by us under the merger agreement or at the express request or direction of Sempra Energy or Merger Sub, or resulting from our entering into the merger agreement or the announcement of the merger; and

	•	changes to any law or generally accepted accounting principles.

The merger agreement defines the term “material adverse effect” with respect to Sempra Energy differently. With respect to Sempra Energy, “material adverse effect” is defined to mean any change, effect, event, occurrence, state of facts or development which, individually or in the aggregate, would reasonably be expected to prevent, materially delay or materially impede Sempra Energy or Merger Sub’s ability to consummate the merger or other transactions contemplated by the merger agreement.

Conduct of Our Business Pending the Merger

Under the merger agreement, we have agreed that, unless Sempra Energy gives us its prior written consent or as otherwise contemplated by the merger agreement, until the effective time of the merger, we and our subsidiaries will:


	•	carry on our business only in the ordinary course consistent with our past practices and in compliance in all material respects with all applicable laws; and

	•	use our commercially reasonable efforts to:


	•	preserve intact our current business organizations;

	•	preserve our relationships with our customers, suppliers, employees, consultants, licensors, licensees, landlords, distributors, governmental authorities and others with whom we have business dealings.

We have also agreed that during the same time period, subject to certain exceptions, and again, unless Sempra Energy gives us its prior written consent, and except as otherwise contemplated by the merger agreement, we and our subsidiaries will not, among other things:


	•	declare, set aside or pay dividends on, or make any other distributions in respect of, our capital stock or the capital stock of our subsidiaries (other than dividends or distributions made from a subsidiary to us or to another one of our subsidiaries and regular quarterly cash dividends of up to $0.26 per share per quarter on our shares of common stock);

	•	except as required by law, pay, discharge, release, waive, settle or satisfy any material claims, liabilities, obligations or litigation, other than the payment, discharge, settlement or satisfaction in the ordinary course of business consistent with our past practices or in accordance with their terms, of liabilities disclosed in our most recent consolidated financial statements filed prior to the date of the merger agreement, or incurred since the date of such financial statements in the ordinary course of business consistent with our past practices, provided that such settlements do not involve out-of-pocket expenditures by us in excess of $100,000 in the aggregate and will not reasonably be expected to have a material adverse impact upon our operations or the operations of our subsidiaries;

	•	enter into, modify, cancel or terminate any contract or waive, release or assign any rights or claims thereunder that if so done, such action would reasonably be excepted to impair in any material respect our ability to perform our obligations under the merger agreement or the ability of our subsidiaries to do the same, prevent or materially impede, interfere with, hinder or delay the consummation of the merger, or impair in any material respect our ability and the ability of our subsidiaries to conduct our businesses as currently conducted;

	•	enter into any contract to purchase, rent, lease, use, borrow or otherwise obtain rights to use any transportation or storage facilities or assets owned by third parties (other than contracts with a term of 60 days or less, entered into solely for the purpose of maintaining the operational reliability of certain of our storage facilities);

	•	enter into any contract or take any action whereby the consummation of the merger or compliance by us or by our subsidiaries with the merger agreement could reasonably be expected to conflict with, result in a violation, breach or default under, give rise to a right of termination, modification, cancellation or acceleration of any obligation or to the loss of a benefit under, or result in the creation of any lien in or upon our or our subsidiaries’ properties, rights or other assets under, require us or our subsidiaries to license or transfer any of our intellectual property or other material assets under, give rise to any increased,


		additional, accelerated, or guaranteed right or entitlements of any third party under, or result in any material alteration of, any provision of such contract;

	•	take any action that is intended or would reasonably be expected to result in the conditions precedent to the consummation of the merger not being satisfied.

Acquisition Proposals

We have agreed that, until the earlier of the effective time of the merger or the termination of the merger agreement pursuant to the terms described below, neither we, nor any of our subsidiaries, our officers and directors, nor those of our subsidiaries, will directly or indirectly:


	•	solicit, initiate, knowingly encourage or knowingly facilitate any inquiry, proposal or offer from a person or group of persons relating to, or that could reasonably be expected to lead to, any direct or indirect acquisition or purchase of assets or businesses that constitute 20% or more of our and our subsidiaries’ revenues, net income or assets, taken as a whole, or 20% or more of any class of our equity securities, any tender offer or exchange offer that if consummated would result in any person or group of persons beneficially owning 20% or more of any class of our equity securities, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, share exchange or similar transaction involving us or our subsidiaries pursuant to which any person or group of persons or the equity holders of any person or group of persons would own 20% or more of any class of our equity securities or of any resulting parent company of us, which proposal we refer to as a “takeover proposal,” or the making of any such takeover proposal;

	•	enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish any information with respect to, or otherwise cooperate in any way with, any takeover proposal; or

	•	waive, terminate, modify or fail to enforce any contractual “standstill” provision or similar obligation of any person other than Sempra Energy.

We have also agreed that we will not authorize or permit our or our subsidiaries’ investment bankers, financial advisors, attorneys, accountants, consultants, directors, officers, employees, advisors or other representatives or agents to take any of the actions listed above. Additionally, we agreed to cease any and all discussions or negotiations with respect to any takeover proposal that were existing as of the date of the merger agreement.

In the event that we receive a written takeover proposal, we must, within 24 hours, provide Sempra Energy with oral and written notice of the material terms of such takeover proposal and the identity of the third party making the takeover proposal, and we must keep Sempra Energy informed in all material respects of the status and details of any such takeover proposal. In addition, we must publicly reaffirm the recommendation of our board of directors to our stockholders in favor of the merger agreement and the merger within 10 business days of receipt of a written request from Sempra Energy to do so, except that our board of directors may adversely change its recommendation pursuant to the procedures described below.

We may engage in negotiations with, and furnish nonpublic information to, any third party that makes a bona fide takeover proposal so long as:


	•	our board of directors or any committee thereof reasonably determines in good faith (after consultation with our outside legal counsel and financial advisor) that the takeover proposal is or is reasonably likely to result in a takeover proposal (with all thresholds in the above definition of takeover proposal changed to 50%) that our board of directors reasonably determines in good faith (after consultation with our outside legal counsel and financial advisor), if accepted, is reasonably likely to be completed on the terms proposed, taking into account all aspects of the proposal, and is more favorable to our stockholders from a financial point of view than the merger, and after taking into account any written proposal by Sempra Energy to amend the terms of the merger, which takeover proposal we sometimes refer to as a “superior proposal;”


	•	the takeover proposal was made after the date of the merger agreement and was not the result of a material breach of our covenant not to solicit any takeover proposals;

	•	our board of directors reasonably determines in good faith (after consultation with our outside legal counsel and financial advisor) that failure to engage in negotiations or furnish nonpublic information would be inconsistent with its fiduciary obligations to our stockholders;

	•	concurrently with providing nonpublic information to any third party, we furnish Sempra Energy with the same information to the extent that it has not been previously furnished; and

	•	we receive from such third party an executed confidentiality agreement containing terms that are at least as restrictive as the terms in the confidentiality agreement between us and Sempra Energy.

Prior to the time that our stockholders vote to adopt the merger agreement and approve the merger, our board of directors may withdraw, modify or qualify in a manner adverse to Sempra Energy, its recommendation to our stockholders in favor of the merger agreement and the merger and may take any other action or make any public statement in connection with such recommendation that is inconsistent with such recommendation, and may adopt or recommend, or propose publicly to adopt or recommend, any takeover proposal, provided that:


	•	a takeover proposal has been made by a third party after the date of the merger agreement;

	•	the takeover proposal was not the result of a material breach of our covenant not to solicit any takeover proposals;

	•	our board of directors concludes that the takeover proposal constitutes a superior proposal; and

	•	we give Sempra Energy and Merger Sub at least four business days prior written notice that our board of directors has received a superior proposal and intends to change its recommendation to our stockholders with respect to the merger and the merger agreement, and we provide along with such notice, the material terms and conditions of the superior proposal and a copy of the relevant proposed transaction agreements with the third party making such superior proposal and any other materials submitted with such proposal.

We have agreed to, and have agreed to cause our legal and financial advisors to, during the four-business day notice period, negotiate with Sempra Energy and Merger Sub in good faith to make adjustments to the terms and conditions of the merger agreement so that the takeover proposal that our board of directors has determined to be a superior proposal will no longer be a superior proposal. In addition, if any material revisions, as determined by our board of directors in good faith, are made to the superior proposal during this notice period, we have agreed to deliver a new written notice to Sempra Energy and Merger Sub, except that the notice period will be reduced to two business days.

Once our board of directors has changed its recommendation in response to a superior proposal, our board of directors may adopt, recommend, or publicly propose to adopt or recommend, or approve our entering into any agreement constituting or relating to, or that is intended to or could reasonably be expected to lead to, a takeover proposal, and we may terminate the merger agreement and enter into any such agreement, provided that our board of directors concludes in good faith (after consultation with our outside legal counsel), that in light of the superior proposal, its failure to terminate the merger agreement would be inconsistent with its fiduciary duties to our stockholders.

In addition to the foregoing, in response to a material development or change in material circumstances occurring or arising after the date of the merger agreement and not relating to any takeover proposal, if the existence and material consequences of such change were not known by our board of directors prior to the date of the merger agreement, our board of directors may withdraw, modify or qualify in a manner adverse to Sempra Energy, its recommendation to our stockholders in favor of the merger agreement and the merger, but only if our board of directors concludes in good faith (after consultation with our outside legal counsel) that its failure to do so would be inconsistent with its fiduciary duties to our stockholders.

Unless the merger agreement is validly terminated in accordance with the terms set forth in the merger agreement, you will be entitled to vote to approve the merger and merger agreement, even if the board of directors has changed its recommendation to you with respect to the merger and merger agreement.

Employee Benefits

For a period of 12 months after the effective time of the merger, Sempra Energy will cause our employees and the employees of our subsidiaries as of the effective time to receive a base salary or hourly wage that is substantially similar to either those provided by Sempra Energy and its subsidiaries to their similarly situated employees or those provided by us and our subsidiaries immediately prior to the effective time, provided that, subject to applicable law and the honoring of existing agreements, nothing shall limit the right of Sempra Energy or its subsidiaries to terminate our employees or the employees of our subsidiaries after the closing date of the merger. Additionally, for a period of 12 months after the effective time, such employees will be entitled to receive employee welfare and retirement benefits which are substantially similar in the aggregate to either those provided by Sempra Energy and its subsidiaries to their similarly situated employees or those provided by us and our subsidiaries immediately prior to the effective time, provided that nothing will require Sempra Energy or its subsidiaries to continue any specific benefit plan, nor will Sempra Energy or its subsidiaries be obligated to continue or adopt any plans or arrangements providing for the issuance of any shares of capital stock or the right to receive any such shares.

Sempra Energy has agreed to recognize the service of our employees and the employees of our subsidiaries to us and to our subsidiaries, as if such service had been performed with Sempra Energy or its subsidiaries, for purposes of determining eligibility for and vesting (but not benefit accrual) under certain employee benefit plans, except if such treatment would result in duplicative benefits.

Agreement to Take Further Action and to Use Commercially Reasonable Efforts

Subject to the terms and conditions of the merger agreement, each party has agreed to use its, and cause its subsidiaries to use their, 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. Among other things, each party has agreed to prepare and file as soon as reasonably practicable all documentation necessary to consummate the merger, including the appropriate filings pursuant to the Hart-Scott Rodino Antitrust Improvements Act, known as the HSR Act. Each party has also agreed to use its commercially reasonable efforts to cooperate with the other party in connection with any filing or any investigation or other inquiry, to keep the other party reasonably informed on the status of matters related to the transactions contemplated by the merger agreement, including furnishing the other with any written communications received from any governmental authority or received in connection with an action brought by a private party, and to permit the other party to review and consult with them in advance of any communication to or meeting with any governmental authority.

Each party has committed to cooperate with each other and use commercially reasonable efforts to contest and resist any action challenging the merger and to have removed any judgment, injunction or restraining order that prohibits, prevents or restricts consummation of the transactions contemplated by the merger agreement. Additionally, each party has agreed to use its best efforts to resolve any objections asserted with respect to the merger under any antitrust law; however, neither party is required to take any actions which requires that party to sell, hold separate or otherwise dispose of any business or assets or conduct its or its subsidiaries’ business in any specified manner, or any action which is reasonably likely to have a material adverse effect on the condition, business, assets, liabilities or results of operations of either party, taken individually or in the aggregate, or that is not conditioned on the consummation of the merger.

Additionally, Sempra Energy has agreed to vote (or cause to be voted) any shares of common stock owned by it or any of its affiliates in favor of the adoption of the merger agreement and the approval of the merger.

Conditions to the Merger

The consummation of the merger is subject to certain conditions contained in the merger agreement. If those conditions are not satisfied or waived, neither we nor Sempra Energy and Merger Sub would be obligated to effect the merger. If we waive any of the conditions to the merger, we will not re-solicit proxies.

	•	Sempra Energy and Merger Sub must have performed in all material respects all of their agreements, covenants and obligations required to be performed by each of them under the merger agreement prior to the effective time of the merger; and

	•	Sempra Energy must deliver to us certain other certificates.

The merger agreement may be terminated and the merger abandoned at any time prior to the effective time of the merger in any of the following ways:


	•	by mutual written consent of Sempra Energy, Merger Sub and us;

	•	by either us or Sempra Energy in the event that any law or order permanently restraining, enjoining or otherwise preventing the consummation of the merger becomes final and nonappealable;

	•	by either us or Sempra Energy if the merger is not consummated by April 30, 2009, if the failure to consummate the merger on or before such date is not caused by a breach of obligations under the merger agreement by the party seeking to terminate;


	•	by either us or Sempra Energy in the event that our stockholders do not adopt the merger agreement and approve the merger at the special meeting, if the failure to obtain stockholder approval is not caused by a breach of obligations under the merger agreement by the party seeking to terminate;

	•	by either us or Sempra Energy in the event of a breach by the other party of any representation, warranty, covenant or agreement contained in the merger agreement such that the related conditions to consummation of the merger discussed above would not be satisfied, provided that:

	•	the party seeking to terminate is not then in material breach of any representation, warranty, covenant or other agreement in the merger agreement that would permit the other party to refuse to consummate the merger pursuant to the conditions discussed above;


	•	by Sempra Energy in the event that our board of directors adversely changes its recommendation in favor of the adoption of the merger agreement and the approval of the merger, as discussed above; or

	•	by us, in order to accept a superior proposal, subject to the terms discussed above and the payment of a termination fee by us to Sempra Energy.

Termination Fees and Expenses


	•	Sempra Energy terminates the merger agreement as outlined above because our board of directors adversely changes its recommendation in favor of the adoption of the merger agreement and the approval of the merger;

	•	we terminate the merger agreement as outlined above in order to accept a superior proposal; or

	•	either we or Sempra Energy terminates the merger agreement because the merger has not been consummated by April 30, 2009 and, prior to such termination, a third party takeover proposal was publicly announced or was otherwise publicly known; or

	•	either we or Sempra Energy terminates the merger agreement because our stockholders do not adopt the merger agreement and approve the merger and, prior to the special meeting, a third party takeover proposal was publicly announced or was otherwise publicly known.

Regulatory Approvals

The HSR Act and the rules and regulations promulgated thereunder required us and Sempra Energy to file notification and report forms with respect to the merger and related transactions with the Antitrust Division of the U.S. Department of Justice and the U.S. Federal Trade Commission. We and Sempra Energy filed our notification and report forms on August • , 2008. We thereafter were required to wait for the expiration or early termination of the statutory waiting period before completing the merger.

We and Sempra Energy are in the process of obtaining the necessary regulatory approvals, consents and authorizations from the Federal Communications Commission. We have been advised by the Alabama Public Service Commission that its approval is not required to consummate the merger.

Amendment and Waiver

Sempra Energy, Merger Sub and we may amend the merger agreement at any time. However, after our stockholders approve the merger agreement, no amendment may be made that requires further approval by our stockholders without such further approval having been obtained.

Each party to the merger agreement may extend the time for performance of any of the obligations or other acts of the other parties under the merger agreement, to the extent permitted by applicable law, waive any inaccuracies in the representations and warranties contained in the merger agreement, and, to the extent permitted by applicable law, waive compliance with any of the agreements or conditions in the merger agreement other than the restrictions on amendments to the merger agreement requiring stockholder approval described above.

Financing

The consummation of the merger is not contingent upon Sempra Energy obtaining financing. Sempra Energy has represented to us that it or Merger Sub has sufficient cash available, either through cash on hand or through committed availability under existing credit facilities, directly or through one or more of its affiliates, to pay the aggregate merger consideration described above.

MARKET PRICES OF THE COMPANY’S STOCK

EnergySouth’s common stock is traded on the Nasdaq Global Select Market under the symbol “ENSI.” On August 8, 2008, there were 8,115,733 shares of common stock outstanding, held by approximately 1,100 stockholders of record. Because many of the Company’s shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

The following table shows, for the periods indicated, the reported high and low sale prices per share of the common stock on the Nasdaq Global Select Market and the amount of dividends paid per outstanding share:

On [ • ] , 2008, the last full trading day

prior to the date of the first mailing of this proxy statement, the closing market price of the common stock on the Nasdaq Global Select Market was $ [ • ] per share. Stockholders should obtain a current market quotation for the common stock before making any decision with respect to the merger.

We are limited in our ability to declare and pay dividends on our common stock by the merger agreement, which provides that we will not pay any dividend except for regular quarterly cash dividends in the ordinary course of business consistent with past practice (and subject to the other limitations specified in the merger agreement) not to exceed $0.26 per share. Our long-term debt instruments and credit agreements also contain certain debt to equity ratio requirements and restrictions on the payment of cash dividends and the purchase of shares of our capital stock, which are not expected to have a significant impact on our ability to pay dividends in the future. See “The Merger Agreement — Conduct of Our Business Pending the Merger.”

APPRAISAL RIGHTS

Holders of EnergySouth common stock who dissent and do not vote in favor of the merger are entitled to certain appraisal rights under Delaware law in connection with the merger, as described below and in Annex C hereto. Holders who perfect their appraisal rights and strictly follow certain procedures in the manner prescribed by Section 262 of the DGCL will be entitled to receive payment of the fair value of their shares, as determined by appraisal proceedings, in cash from EnergySouth, as the surviving corporation in the merger.

ANY ENERGYSOUTH STOCKHOLDER WHO WISHES TO EXERCISE APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE HIS OR HER RIGHT TO DO SO SHOULD REVIEW ANNEX C CAREFULLY AND SHOULD CONSULT HIS OR HER LEGAL ADVISOR, SINCE FAILURE TO COMPLY STRICTLY AND TIMELY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS.

Record holders of the shares of EnergySouth common stock that elect to exercise their appraisal rights with respect to the merger are referred to herein as “dissenting stockholders,” and the shares of EnergySouth common stock with respect to which they exercise appraisal rights are referred to herein as “dissenting shares.” If an EnergySouth stockholder has a beneficial interest in shares of EnergySouth common stock that are held of record in the name of another person, such as a broker or nominee, and such EnergySouth stockholder desires to perfect whatever appraisal rights such beneficial EnergySouth stockholder may have, such beneficial EnergySouth stockholder must act promptly to cause the holder of record timely and properly to follow the steps summarized below.

A VOTE IN FAVOR OF THE MERGER BY AN ENERGYSOUTH STOCKHOLDER WILL RESULT IN A WAIVER OF SUCH HOLDER’S RIGHT TO APPRAISAL RIGHTS.

When the merger becomes effective, EnergySouth stockholders who strictly comply with the procedures prescribed in Section 262 of the DGCL will be entitled to a judicial appraisal of the fair value of their shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, and to receive payment of the fair value of their shares in cash from EnergySouth, as the surviving corporation in the merger. The following is a brief summary of the statutory procedures that must be followed by a common stockholder of EnergySouth in order to perfect appraisal rights under the DGCL. This summary is not intended to be complete and is qualified in its entirety by reference to Section 262 of the DGCL, the text of which is included as Annex C to this proxy statement. We advise any EnergySouth stockholder considering exercising appraisal rights to consult legal counsel.

In order to exercise appraisal rights under Delaware law, a stockholder must be the stockholder of record of the shares of EnergySouth common stock as to which appraisal rights are to be exercised on the date that the written demand for appraisal described below is made, and the stockholder must continuously hold such shares through the effective date of the merger.

While EnergySouth stockholders electing to exercise their appraisal rights under Section 262 of the DGCL are not required to vote against the approval of the merger, a vote in favor of approval of the merger will result in a waiver of the holder’s right to appraisal rights. EnergySouth stockholders electing to demand the appraisal of such

stockholder’s shares shall deliver to EnergySouth, before the taking of the vote on the merger, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs EnergySouth of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger shall not constitute such a demand. Please see the discussion below under the heading “Written Demand” for additional information regarding written demand requirements.

Within ten days after the effective time of the merger, EnergySouth, as the surviving corporation, must provide notice of the date of effectiveness of the merger to all EnergySouth stockholders who have not voted for approval of the merger agreement and who have otherwise complied with the requirements of Section 262 of the DGCL.

An EnergySouth stockholder who elects to exercise appraisal rights must mail or deliver the written demand for appraisal to:

EnergySouth, Inc.

P.O. Box 2248

Mobile, Alabama 36652

Attn: G. Edgar Downing, Jr., Secretary

Within 120 days after the effective date of the merger, any dissenting stockholder, and any beneficial owner of shares of EnergySouth stock held either in a voting trust or by a nominee on behalf of such beneficial owner, that has strictly complied, or has caused the applicable dissenting stockholder to strictly comply, with the procedures prescribed in Section 262 of the DGCL will be entitled, upon written request, to receive from EnergySouth, as the surviving corporation, a statement of the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received by EnergySouth, and the aggregate number of holders of those shares. This statement must be mailed to the requesting stockholder within ten days after the stockholder’s written request has been received by EnergySouth, as the surviving corporation, or within ten days after the date of the effective date of the merger, whichever is later.

Within 120 days after the effective date of the merger, (1) EnergySouth, as the surviving corporation, (2) any dissenting stockholder that has strictly complied with the procedures prescribed in Section 262 of the DGCL or (3) any beneficial owner of shares of EnergySouth stock held either in a voting trust or by a nominee on behalf of such beneficial owner that has caused the applicable dissenting stockholder to strictly comply with the procedures prescribed in Section 262 of the DGCL may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of each share of EnergySouth stock of all dissenting stockholders. If a petition for an appraisal is timely filed, then after a hearing on the petition, the Delaware Court of Chancery will determine which EnergySouth stockholders are entitled to appraisal rights and then will appraise the shares of EnergySouth common stock owned by those stockholders by determining the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger, together with the interest to be paid, if any, on the amount determined to be the fair value. If no petition for appraisal is filed with the Delaware Court of Chancery by EnergySouth, as the surviving corporation, any dissenting stockholder or any beneficial holder described above within 120 days after the effective time of the merger, then the dissenting stockholders’ rights to appraisal will cease, and they will be entitled only to receive merger consideration paid in the merger on the same basis as other EnergySouth unaffiliated stockholders. Inasmuch as EnergySouth, as the surviving corporation, has no obligation to file a petition, any EnergySouth stockholder who desires a petition to be filed is advised to file it on a timely basis. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective time of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at the rate that is 5% over the Federal Reserve discount rate (including any surcharges) as established from time to time during the period between the effective time of the merger and the date of payment of the judgment.

The cost of the appraisal proceeding may be determined by the Delaware Court of Chancery and taxed upon the parties as the court deems equitable in the circumstances. Upon application of a dissenting stockholder that has strictly complied with the procedures prescribed in Section 262 of the DGCL, the court may order that all or a portion of the expenses incurred by any dissenting stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees, and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal. In the absence of this determination or assessment, each party

bears its own expenses. A dissenting stockholder who has timely demanded appraisal in compliance with Section 262 of the DGCL will not, after the effective time of the merger, be entitled to vote EnergySouth common stock subject to such demand for any purpose or to receive payment of dividends or other distributions on EnergySouth common stock, except for dividends or other distributions payable to stockholders of record at a date prior to the effective time of the merger.

At any time within 60 days after the effective time of the merger, any dissenting stockholder will have the right to withdraw the stockholder’s demand for appraisal and to accept the right to receive merger consideration in the merger on the same basis on which EnergySouth common stock is converted in the merger. After this 60 day period, a dissenting stockholder that has strictly complied with the procedures prescribed in Section 262 of the DGCL may withdraw his or her demand for appraisal only with the written consent of EnergySouth or Sempra Energy. If a petition has been timely filed in the Delaware Court of Chancery demanding appraisal, such petition will not be dismissed as to any EnergySouth stockholder, without the approval of the Delaware Court of Chancery, which may be conditioned on any terms the Delaware Court of Chancery deems just. However, such approval is not required for any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the merger consideration within 60 days after the effective date of the merger.

Written Demand

When submitting a written demand for appraisal under Delaware law, the written demand for appraisal must reasonably inform EnergySouth of the identity of the stockholder of record making the demand and indicate that the stockholder intends to demand appraisal of the stockholder’s shares. A demand for appraisal must be executed by or for an EnergySouth common stockholder of record, fully and correctly, as that stockholder’s name appears on the stockholder’s stock certificate. If EnergySouth common stock is owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, the demand must be executed by the fiduciary. If EnergySouth common stock is owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by or for all joint owners. An authorized agent, including an agent for two or more joint owners, must execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner and expressly disclose the fact that, in exercising the demand, he, she or it is acting as agent for the record owner.

A record owner who holds EnergySouth common stock as a nominee for other beneficial owners of the shares may exercise appraisal rights with respect to EnergySouth common stock held for all or less than all beneficial owners of EnergySouth stock for which the holder is the record owner. In that case, the written demand must state the number of shares of EnergySouth common stock covered by the demand. Where the number of shares of EnergySouth common stock is not expressly stated, the demand will be presumed to cover all shares of EnergySouth common stock outstanding in the name of that record owner. Beneficial owners who are not record owners and who intend to exercise appraisal rights should instruct the record owner to comply strictly with the statutory requirements with respect to the delivery of written demand prior to the taking of the vote on the merger.

EnergySouth stockholders considering whether to seek appraisal should bear in mind that the fair value of their EnergySouth common stock determined under Section 262 of the DGCL could be more than, the same as or less than the value of the right to receive merger consideration in the merger. Also, EnergySouth and Sempra Energy reserve the right to assert in any appraisal proceeding that, for purposes thereof, the “fair value” of EnergySouth common stock is less than the value of the merger consideration to be issued in the merger.

Any stockholder who fails to strictly comply with the requirements of Section 262 of the DGCL, attached as Annex C to this proxy statement will forfeit his, her or its rights to dissent from the merger and to exercise appraisal rights and will receive merger consideration on the same basis as all other stockholders.

THE PROCESS OF DISSENTING REQUIRES STRICT COMPLIANCE WITH TECHNICAL PREREQUISITES. THOSE INDIVIDUALS OR ENTITIES WISHING TO DISSENT AND TO EXERCISE THEIR APPRAISAL RIGHTS SHOULD CONSULT WITH THEIR OWN LEGAL COUNSEL IN CONNECTION WITH COMPLIANCE UNDER SECTION 262 OF THE DGCL. TO THE EXTENT THERE ARE ANY INCONSISTENCIES BETWEEN THE FOREGOING SUMMARY AND SECTION 262 OF THE DGCL, SECTION 262 OF THE DGCL SHALL CONTROL.

ADJOURNMENT OF THE SPECIAL MEETING (PROPOSAL NO. 2)

Proposal for Adjournment

EnergySouth is asking its stockholders to vote on a proposal to adjourn the special meeting, if necessary or appropriate, in order to allow for the solicitation of additional proxies if there are insufficient votes at the time of the meeting to adopt the merger agreement and approve the merger. We currently do not intend to propose adjournment at our special meeting if there are sufficient votes to adopt the merger agreement and approve the merger. The proposal to adjourn our special meeting for the purpose of soliciting additional proxies requires the affirmative vote of the holders of a majority of the shares of EnergySouth common stock present or represented by proxy and entitled to vote on the matter.

The board of directors recommends that you vote “FOR” the adjournment of the special meeting, if necessary, to solicit additional proxies.

SECURITY OWNERSHIP OF MANAGEMENT AND PRINCIPAL STOCKHOLDERS

The table below sets forth, as of August 8, 2008, certain information with respect to the beneficial ownership of the Company’s common stock by (1) each person known by the Company to own beneficially more than five percent (5%) of the outstanding shares of common stock; (2) each of our named executive officers; (3) each director of the Company; and (4) all directors and executive officers as a group.

Beneficial ownership is determined in accordance with the rules of the SEC that deem shares to be beneficially owned by any person who has or shares voting power or investment power with respect to such shares. Shares of the Company’s common stock that are issuable to the identified person pursuant to stock options or other awards under the Company’s equity incentive compensation plans within 60 days after August 8, 2008 are deemed to be outstanding and to be beneficially owned by the person holding such awards for the purpose of computing the percentage ownership of such person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. For this purpose, since all EnergySouth equity incentive compensation awards, both vested and not vested, will become fully vested in connection with the merger, we have assumed that all such awards are fully exercisable within 60 days of the date of this table. As a result, the percentage of outstanding shares of any person as shown in the following table does not necessarily reflect the person’s actual voting power at any particular date.

The business address of each officer and director is c/o EnergySouth, Inc., 2828 Dauphin Street, Mobile, Alabama 36606 .

STOCKHOLDER PROPOSALS

If the merger is completed, there will be no public participation in any future meetings of our stockholders. If the merger is not completed, our stockholders will continue to be entitled to attend and participate in our stockholder meetings. Pending consummation of the merger, we do not intend to conduct any further annual meetings of stockholders.

If the merger is not consummated, our stockholders are permitted to submit proposals that they believe should be voted on at the 2009 annual meeting and recommend persons who they believe should be nominated for election to the board of directors. Pursuant to Rule 14a-8 under the Exchange Act, some stockholder proposals may be eligible for inclusion in our 2009 proxy statement. Any such stockholder proposals intended for inclusion in our 2009 proxy statement must be submitted, along with proof of ownership of our stock in accordance with Rule 14a-8(b)(2), to our principal executive offices to the attention of our Secretary. Failure to deliver a proposal by this means may result in it not being deemed timely received. We must [have] receive [d] all such submissions no later than August 20, 2008. Submitting a stockholder proposal does not guarantee that we will include it in our proxy statement.

Notice of a stockholder proposal intended to be submitted for a vote at the 2009 annual meeting outside the process of Rule 14a-8 (i.e., not for inclusion in our 2009 proxy statement) will be considered untimely if not received by our Secretary no later than November 3, 2008. If notice of such a stockholder proposal is received by the Secretary after such date, then the proxy card for the 2009 annual meeting may confer discretionary authority for Company representatives to vote on such matter in their discretion, without a description of such matter being included in the proxy statement.

The Corporate Governance and Nominating Committee reviews all stockholder proposals and makes recommendations to the board of directors for action on such proposals.

OTHER MATTERS

At this time, we know of no other matters to be submitted to our stockholders at the special meeting or any adjournment or postponement of the special meeting. If any other matters properly come before the special meeting or any adjournment or postponement of the special meeting, it is the intention of the persons named in the enclosed proxy card to vote the shares they represent in accordance with their judgment.

HOUSEHOLDING

Pursuant to the SEC’s “householding” rules, we may deliver a single proxy statement to an address shared by two or more of our stockholders. This delivery method can result in significant costs savings for us. To take advantage of this opportunity, we have delivered only one proxy statement to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We undertake to deliver promptly upon written or oral request a separate copy of the proxy statement, as requested, to a stockholder at a shared address to which a single copy of that document was delivered. If you prefer to receive, either now or in the future, separate copies of any proxy statement or annual report or if you are now receiving multiple copies and prefer to receive a single copy, either now or in the future, you can submit your request by writing to us at the following address: EnergySouth, Inc., P.O. Box 2248, Mobile, Alabama 36652, Attention: Martha Loper, Investor Relations, or by telephoning (251) 450-4631.

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:

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.

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 Alston & Bird LLP, One Atlantic Center, 1201 West Peachtree Street, Atlanta, GA, unless another time, date or place is agreed to in writing by Parent and the Company.

A-1

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

A-2

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

A-3

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 Moody’s 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

A-4

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.

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.

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

A-24

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

A-25

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) .

From the Effective Time through the sixth (6th) 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.

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.

A-29

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.

The Board of Directors

EnergySouth, Inc.

2828 Dauphin Street

Mobile, Alabama 36606

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of common stock, par value $0.01 per share (the “Company Common Stock”), of EnergySouth, Inc. (the “Company”) of the consideration to be paid to such holders in the proposed merger (the “Transaction”) of the Company with a wholly-owned subsidiary of Sempra Energy (the “Acquiror”). Pursuant to the Agreement and Plan of Merger (the “Agreement”), among the Company, the Acquiror and a subsidiary of the Acquiror, the Company will become a wholly-owned subsidiary of the Acquiror, and each outstanding share of Company Common Stock, other than shares of Company Common Stock held in treasury or owned by the Acquiror and its affiliates and Dissenting Shares (as defined in the Agreement), will be converted into the right to receive $61.50 per share in cash (the “Consideration”).

In arriving at our opinion, we have (i) reviewed a draft dated July 21, 2008 of the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the industries in which it operates; (iii) compared the proposed financial terms of the Transaction with the publicly available financial terms of certain transactions involving companies we deemed relevant and the consideration received for such companies; (iv) compared the financial and operating performance of the Company with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Company Common Stock and certain publicly traded securities of such other companies; (v) reviewed certain internal financial analyses and forecasts prepared by the management of the Company relating to its business; and (vi) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Company and the Acquiror with respect to certain aspects of the Transaction, and the past and current business operations of the Company, the financial condition and future prospects and operations of the Company, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company or otherwise reviewed by or for us, and we have not independently verified (nor have we assumed responsibility or liability for independently verifying) any such information or its accuracy or completeness. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Company or the Acquiror under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us or derived therefrom, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of the Company to which such analyses or forecasts relate. We express no view as to such analyses or forecasts or the assumptions on which they were based. We have also assumed that the Transaction and the other transactions contemplated by the Agreement will be consummated as described in the Agreement, and that the definitive Agreement will not differ in any material respects from the draft thereof furnished to us. We have also assumed that the representations and warranties made by the Company and the Acquiror in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or on the contemplated benefits of the Transaction.

B-1

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, of the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction and we express no opinion as to the fairness of the Transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Transaction. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Transaction, or any class of such persons relative to the Consideration to be received by the holders of the Company Common Stock in the Transaction or with respect to the fairness of any such compensation.

We have acted as financial advisor to the Company with respect to the proposed Transaction and will receive a fee from the Company for our services, a substantial portion of which will become payable only if the proposed Transaction is consummated. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. During the two years preceding the date of this letter, we and our affiliates have had commercial or investment banking relationships with the Company and the Acquiror, for which we and such affiliates have received customary compensation. Such services during such period have included acting as (i) lead manager for an offering of $55,000,000 in principal amount of Industrial Revenue Development Bonds in August 2007, the proceeds of which were loaned to a subsidiary of the Company; (ii) joint book-running manager for the Acquiror’s offering of $500,000,000 in principal amount of notes in June 2008; (iii) seller in a $161,000,000 share repurchase program by the Acquiror of its common stock that concluded in September 2007; and (iv) lead manager for the offering of $161,000,000 in principal amount of Industrial Development Revenue Refunding Bonds by a subsidiary of the Acquiror beginning in September 2006. In addition, our commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of the Company and the Acquiror, for which it receives customary compensation or other financial benefits. In the ordinary course of our businesses, we and our affiliates may actively trade the debt and equity securities of the Company or the Acquiror for our own account or for the accounts of customers and, accordingly, we may at any time hold long or short positions in such securities.

On the basis of and subject to the foregoing, it is our opinion as of the date hereof that the consideration to be paid to the holders of the Company Common Stock in the proposed Transaction is fair, from a financial point of view, to such holders.

The issuance of this opinion has been approved by a fairness opinion committee of J.P. Morgan Securities Inc. This letter is provided to the Board of Directors of the Company in connection with and for the purposes of its evaluation of the Transaction. This opinion does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Transaction or any other matter. This opinion may not be disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever except with our prior written approval. This opinion may be reproduced in full in any proxy or information statement mailed to stockholders of the Company but may not otherwise be disclosed publicly in any manner without our prior written approval.

Very truly yours,

Annex C

Section 262 of the General Corporation Law of the State of Delaware

§ 262. Appraisal Rights

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of § 251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the

C-1

procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective

C-2

date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the

C-3

expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
