a Permitted Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by the Underwriter expressly for use therein.

(e) The Company agrees that if there occurs an event or development as a result of which the Pricing Disclosure Package would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will notify the Underwriter so that any use of the Pricing Disclosure Package may cease until it is amended or supplemented.

SECTION 4 COVENANTS OF THE COMPANY. The Company covenants with the Underwriter as follows:

(a) The Company, on or prior to the Closing Date, will deliver to the Underwriter conformed copies of the Registration Statement as originally filed and of all amendments thereto, heretofore or hereafter made, including any post-effective amendment (in each case including all exhibits filed therewith, and including unsigned copies of each consent and certificate included therein or filed as an exhibit thereto, except exhibits incorporated by reference, unless specifically requested). As soon as the Company is advised thereof, it will advise the Underwriter orally of the issuance of any stop order under the 1933 Act with respect to the Registration Statement, or the institution of any proceedings for that purpose or pursuant to Section 8A of the 1933 Act against the Company or related to the offering, of which the Company shall have received notice, and will use its best efforts to prevent the issuance of any such stop order and to secure the prompt removal thereof, if issued. The Company will deliver to the Underwriter sufficient conformed copies of the Registration Statement, the Basic Prospectus, the Pricing Prospectus and the Final Supplemented Prospectus and of all supplements and amendments thereto (in each case without exhibits) and, from time to time, as many copies of the Basic Prospectus, the Pricing Prospectus and the Final Supplemented Prospectus as the Underwriter may reasonably request for the purposes contemplated by the 1933 Act or the 1934 Act.

(b) The Company will furnish the Underwriter with written or electronic copies of each amendment and supplement to the Final Supplemented Prospectus relating to the offering of the Senior Notes in such quantities as the Underwriter may from time to time reasonably request. If, during the period (not exceeding nine months) when the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) shall be required by law in connection with the sale of any Senior Notes by the Underwriter, any event relating to or affecting the Company, or of which the Company shall be advised in writing by the Underwriter, shall occur, which in the opinion of the Company or of Underwriter’s counsel should be set forth in a supplement to or an amendment of the Final Supplemented Prospectus, as the case may be, in order to make the Final Supplemented Prospectus not misleading in the light of the circumstances when it (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933

Act) is delivered, or if for any other reason it shall be necessary during such period to amend or supplement the Final Supplemented Prospectus or to file under the 1934 Act any document incorporated by reference in the Final Supplemented Prospectus in order to comply with the 1933 Act or the 1934 Act, the Company forthwith will (i) notify the Underwriter to suspend solicitation of purchases of the Senior Notes and (ii) at its expense, make any such filing or prepare and furnish to the Underwriter a reasonable number of copies of a supplement or supplements or an amendment or amendments to the Final Supplemented Prospectus which will supplement or amend the Final Supplemented Prospectus so that, as supplemented or amended, it will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances when the Final Supplemented Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) is delivered, not misleading or which will effect any other necessary compliance. In case the Underwriter is required to deliver a prospectus in connection with the sale of any Senior Notes after the expiration of the period specified in the preceding sentence, the Company, upon the request of the Underwriter, will furnish to the Underwriter, at the expense of the Underwriter, a reasonable quantity of a supplemented or amended prospectus, or supplements or amendments to the Final Supplemented Prospectus, complying with Section 10(a) of the 1933 Act. During the period specified in the second sentence of this subsection, the Company will continue to prepare and file with the Commission on a timely basis all documents or amendments required under the 1934 Act and the rules and regulations thereunder; provided, that the Company shall not file such documents or amendments without also furnishing copies thereof prior to such filing to the Underwriter and Dewey & LeBoeuf LLP.

(c) The Company will endeavor, in cooperation with the Underwriter, to qualify the Senior Notes for offering and sale under the applicable securities laws of such states and the other jurisdictions of the United States as the Underwriter may designate; provided, however, that the Company shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to file a consent to service of process or to file annual reports or to comply with any other requirements in connection with such qualification deemed by the Company to be unduly burdensome.

(d) The Company will make generally available to its security holders as soon as practicable but not later than 45 days after the close of the period covered thereby, an earnings statement of the Company (in form complying with the provisions of Rule 158 of the rules and regulations under the 1933 Act) covering a twelve-month period beginning not later than the first day of the Company's fiscal quarter next following the “effective date” (as defined in Rule 158) of the Registration Statement.

(e) As soon as practicable after the date of this Agreement, and in any event within the time prescribed by Rule 424 under the 1933 Act, the Company will file the Final Supplemented Prospectus, in a form approved by the Underwriter, such

approval not to be unreasonably withheld, with the Commission and will advise the Underwriter of such filing and will confirm such advice in writing. Furthermore, the Company will make any other required filings pursuant to Rule 433(d)(1) of the 1933 Act within the time required by such Rule.

(f) During a period of 15 days from the date of this Agreement, the Company will not, without the Underwriter’s prior written consent, directly or indirectly, sell, offer to sell, grant any option for the sale of, or otherwise dispose of, any Senior Notes or any security convertible into or exchangeable into or exercisable for the Senior Notes or any debt securities substantially similar to the Senior Notes (except for the Senior Notes issued pursuant to this Agreement). The Underwriter agrees that commercial paper or other debt securities with scheduled maturities of less than one year are not subject to this Section 4(f).

The Company will pay all expenses incidental to the performance of its obligations under this Agreement, including but not limited to, the expenses of (i) the printing and filing of the Registration Statement as originally filed and of each amendment thereto, (ii) the preparation, issuance and delivery of the certificate(s) for the Senior Notes, (iii) the fees and disbursements of the Company's counsel and accountants, (iv) the qualification of the Senior Notes under securities laws in accordance with the provisions of Section 4(c) hereof, including filing fees and the reasonable fees and disbursements of Dewey & LeBoeuf LLP, counsel for the Underwriter, in connection therewith and in connection with the preparation of any blue sky survey (such fees and disbursements of counsel shall not exceed $3,500), (v) the printing and delivery to the Underwriter of copies of the Registration Statement as originally filed and of each amendment thereto and of the Pricing Prospectus, any Permitted Free Writing Prospectus, the Final Supplemented Prospectus, and any amendments or supplements thereto, (vi) the printing and delivery to the Underwriter of copies of any blue sky survey, (vii) the fee of the Financial Industry Regulatory Authority, Inc. in connection with its review of the offering contemplated by this Agreement, if applicable, (viii) the fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Senior Notes, (ix) any fees payable in connection with the rating of the Senior Notes, (x) the cost and charges of any transfer agent or registrar, and (xi) the cost of qualifying the Senior Notes with The Depository Trust Company.

The pricing term sheet contemplated by Section 3(b) hereto, and any other material required to be filed by the Company pursuant to Rule 433(d) under the 1933 Act, shall have been filed by the Company with the Commission within the applicable time periods prescribed for such filings by Rule 433.

(b) Any required orders of the Federal Energy Regulatory Commission and the Commission permitting the transactions contemplated hereby substantially in accordance with the terms and conditions hereof shall be in full force and effect and shall contain no provision unacceptable to the Underwriter or the Company (but all provisions of such order or orders heretofore entered, copies of which have heretofore been delivered to the Underwriter, are deemed acceptable to the Underwriter and the Company and all provisions of such order or orders hereafter entered shall be deemed acceptable to the Underwriter and the Company unless within 24 hours after receiving a copy of any such order any party to this Agreement shall give notice to the other parties to the effect that such order contains an unacceptable provision).

(1) The opinion, dated the Closing Date, of Balch & Bingham LLP, general counsel for the Company, substantially in the form attached hereto as Schedule III-A

(2) The opinion, dated the Closing Date, of Troutman Sanders LLP, counsel for the Company, substantially in the form attached hereto as Schedule III-B.

(d) At the Closing Date, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Registration Statement and the Final Supplemented Prospectus, any material adverse change in the business, properties or financial condition of the Company, whether or not arising in the ordinary course of business, and the Underwriter shall have received a certificate of the President or any Vice President of the Company, and dated as

of the Closing Date, to the effect that (i) there has been no such material adverse change, (ii) the representations and warranties in Section 1 hereof are true and correct with the same force and effect as though expressly made at and as of the Closing Date, (iii) the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied on or prior to the Closing Date and (iv) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose or pursuant to Section 8A of the 1933 Act against the Company or related to the offering have been initiated or, to the knowledge of the Company, threatened by the Commission.

(e) The Underwriter shall have received on the date hereof and shall receive on the Closing Date from Deloitte & Touche LLP, a letter or letters addressed to the Underwriter (which may refer to letters previously delivered to the Underwriter) dated the respective dates of delivery thereof to the effect that: (A) they are an independent registered public accounting firm with respect to the Company within the meaning of the 1933 Act and the rules and regulations under the 1933 Act; (B) in their opinion, the financial statements audited by them and incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, comply as to form in all material respects with the applicable accounting requirements of the 1934 Act and the rules and regulations under the 1934 Act; and (C) on the basis of certain limited procedures performed through a specified date not more than three business days prior to the date of such letter, namely (i) reading the minute books of the Company; (ii) performing the procedures specified by the standards of the Public Company Accounting Oversight Board (United States) for a review of interim financial statement information as described in Statement on Auditing Standards No. 100, “Interim Financial Information,” on the unaudited financial statements, if any, of the Company incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, and on the latest available unaudited financial statements of the Company, if any, for any calendar quarter subsequent to the date of those incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable; and (iii) making inquiries of certain officials of the Company who have responsibility for financial and accounting matters regarding such unaudited financial statements or any specified unaudited amounts derived therefrom (it being understood that the foregoing procedures do not constitute an audit performed in accordance with generally accepted auditing standards and they would not necessarily reveal matters of significance with respect to the comments made in such letter, and accordingly that Deloitte & Touche LLP make no representations as to the sufficiency of such procedures for the Underwriter’s purposes), nothing came to their attention that caused them to believe that: (1) any material modifications should be made to the unaudited condensed financial statements, if any, incorporated by reference in the Registration Statement and the Pricing

Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, for them to be in conformity with GAAP; (2) such unaudited condensed financial statements do not comply as to form in all material respects with the applicable accounting requirements of the 1934 Act as it applies to Form 10-Q and the related published rules and regulations thereunder; (3) the unaudited amounts for Operating Revenues, Earnings Before Income Taxes and Net Income After Dividends on Preferred Stock and the unaudited Ratio of Earnings to Fixed Charges set forth in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, do not agree with the amounts set forth in or derived from the unaudited financial statements for the same period included or incorporated by reference in the Registration Statement; (4) as of a specified date not more than three business days prior to the date of delivery of such letter, there has been any change in the capital stock or long-term debt of the Company or any decrease in net assets as compared with amounts shown in the latest unaudited balance sheet incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, except in each case for changes or decreases which (i) the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, disclose have occurred or may occur, (ii) are occasioned by the declaration of dividends, (iii) are occasioned by draw-downs under existing pollution control financing arrangements, (iv) are occasioned by regularly scheduled payments of capitalized lease obligations, (v) are occasioned by the purchase or redemption of bonds or stock to satisfy mandatory or optional redemption provisions relating thereto, (vi) are occasioned by the reclassification of current maturities of long-term debt, or (vii) are disclosed in such letter; and (5) the unaudited amounts for Operating Revenues, Earnings Before Income Taxes and Net Income After Dividends on Preferred Stock and the unaudited Ratio of Earnings to Fixed Charges for any calendar quarter subsequent to those set forth in (3) above, which, if available, shall be set forth in such letter, do not agree with the amounts set forth in or derived from the unaudited financial statements for the same period or were not determined on a basis substantially consistent with that of the corresponding audited amounts or ratios included or incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable.

(f) On the Closing Date, Dewey & LeBoeuf LLP, counsel for the Underwriter shall have been furnished with such documents and opinions as it may reasonably require for the purpose of enabling it to pass upon the issuance and sale of the Senior Notes as herein contemplated and related proceedings, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Senior Notes as

herein contemplated shall be satisfactory in form and substance to the Underwriter and Dewey & LeBoeuf LLP, counsel for the Underwriter.

(g) No amendment or supplement to the Registration Statement or the Final Supplemented Prospectus filed subsequent to the date of this Agreement (including any filing made by the Company pursuant to Section 13 or 14 of the 1934 Act) shall be unsatisfactory in form to Dewey & LeBoeuf LLP or shall contain information (other than with respect to an amendment or supplement relating solely to the activity of the Underwriter) which, in the reasonable judgment of the Underwriter, shall materially impair the marketability of the Senior Notes.

(h) The Company shall have performed its obligations when and as provided under this Agreement.

If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Underwriter by notice to the Company at any time prior to the Closing Date, and such termination shall be without liability of any party to any other party except as provided in Sections 5, 8 and 10(b) hereof.

SECTION 7 CONDITIONS OF THE OBLIGATIONS OF THE COMPANY. The obligations of the Company shall be subject to the conditions set forth in the first sentence of Section 6(a) and in Section 6(b). In case such conditions shall not have been fulfilled, this Agreement may be terminated by the Company by mailing or delivering written notice thereof to the Underwriter. Any such termination shall be without liability of any party to any other party except as otherwise provided in Sections 5, 8 and 10(b) hereof.

The Company agrees to indemnify and hold harmless the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the 1933 Act, the 1934 Act or otherwise, and to reimburse the Underwriter and such controlling person or persons, if any, for any legal or other expenses incurred by them in connection with defending any actions, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Basic Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus or, if the Company shall furnish to the Underwriter any amendments or any supplements thereto, or shall make any filings pursuant to Section 13 or 14 of the 1934 Act which are incorporated therein by reference, in any Preliminary Prospectus, the Registration Statement, the Basic Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus, the Final Supplemented Prospectus as so amended or supplemented, or in any free writing prospectus used by the Company

other than a Permitted Free Writing Prospectus, or arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any such untrue statement or alleged untrue statement or omission or alleged omission which was made in such Registration Statement, Preliminary Prospectus, Basic Prospectus, Pricing Prospectus, Permitted Free Writing Prospectus or Final Supplemented Prospectus in reliance upon and in conformity with information furnished in writing to the Company by the Underwriter for use therein. The Underwriter agrees, within ten days after the receipt by it of notice of the commencement of any action in respect of which indemnity may be sought by it, or by any person controlling it, from the Company on account of its agreement contained in this Section 8, to notify the Company in writing of the commencement thereof but the omission of the Underwriter so to notify the Company of any such action shall not release the Company from any liability which it may have to the Underwriter or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 8. In case any such action shall be brought against the Underwriter or any such person controlling the Underwriter and the Underwriter shall notify the Company of the commencement thereof as above provided, the Company shall be entitled to participate in (and, to the extent that it shall wish, including the selection of counsel, to direct) the defense thereof, at its own expense. In case the Company elects to direct such defense and select such counsel, the Underwriter or controlling person shall have the right to employ its own counsel, but, in any such case, the fees and expenses of such counsel shall be at the expense of the Underwriter or such controlling person unless the employment of such counsel has been authorized in writing by the Company in connection with defending such action. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent.

The Underwriter agrees to indemnify and hold harmless the Company, its directors and such of its officers who have signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act to the same extent and upon the same terms as the indemnity agreement of the Company set forth in Section 8(a) hereof, but only with respect to alleged untrue statements or omissions made in the Registration Statement, the Preliminary Prospectus, the Basic Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus, or such documents as amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company by the Underwriter for use therein.

SECTION 9 REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY. All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or controlling person, or by, or on behalf of the Company and shall survive delivery of the Senior Notes to the Underwriter.

(b) If this Agreement shall be terminated by the Underwriter pursuant to subsection (a) above or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, then in any such case, the Company will reimburse the Underwriter for the reasonable fees and disbursements of Dewey & LeBoeuf LLP and for the out of pocket expenses (in an amount not exceeding $10,000) reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Senior Notes and, upon such reimbursement, the Company shall be absolved from any further liability hereunder, except as provided in Sections 5 and 8 hereof.

We have acted as general counsel to Mississippi Power Company (the “Company”) in connection with (i) the Company’s issuance of $50,000,000 aggregate principal amount of its Series 2008A 6.00% Senior Notes due November 15, 2013 (the “Notes”) pursuant to a Senior Note Indenture dated as of May 1, 1998, by and between the Company and Wells Fargo Bank, National Association, as successor trustee (the “Trustee”), as heretofore supplemented and as further supplemented by the Ninth Supplemental Indenture dated as of November 21, 2008 (collectively, the “Indenture”); and (ii) the purchase by you of the Notes pursuant to the terms of an Underwriting Agreement dated November 14, 2008 (the “Underwriting Agreement”) between the Company and you (the “Underwriter”). This opinion is being delivered to you pursuant to Section 6(c)(1) thereof.

All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.

In rendering the opinions expressed below, we have examined the registration statement on Form S-3 (File No. 333-152895) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated September 8, 2008 (the “Basic Prospectus”), as supplemented by a preliminary prospectus supplement dated November 14, 2008 (the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act, which, pursuant to Form S-3, incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2007, the Quarterly Reports on Form 10-Q of the Company for the quarters ended March 31, 2008, June 30, 2008 and September 30, 2008 and the Current Reports on Form 8-K of the Company dated March 5, 2008 and October 8, 2008 (the “Pricing Exchange Act Documents”), and a prospectus supplement dated November 14, 2008 (together with the Basic Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report

on Form 8-K of the Company dated November 14, 2008 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”); and the Indenture. We have also examined the free writing prospectus prepared by the Company and filed with the Commission on November 14, 2008 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”). The documents listed in Schedule II to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

In addition, we have examined, and have relied as to matters of fact upon, the documents delivered to you at the closing (except the certificate representing the Notes, of which we have examined a specimen), and we have made such other and further investigations as we deemed necessary to express the opinions hereinafter set forth. In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.

The Indenture and the Underwriting Agreement are herein referred to as the “Agreements.”

We have also examined the opinion of Troutman Sanders LLP to you of even date with respect to matters relating to the Securities Act of 1933, as amended; the Securities Exchange Act of 1934, as amended; the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and to the applicable rules and regulations of the Commission under said Acts and in expressing the opinions stated herein, with respect to such matters, we are relying on such opinion.

Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion, relying as to matters of the federal law of the United States upon the opinion dated the date hereof rendered to you by Troutman Sanders LLP and relying as to matters of New York law upon the opinion dated the date hereof rendered to you by Dewey & LeBoeuf LLP, that:

1. The Company has been duly organized and is validly existing and in good standing as a corporation under the laws of the State of Mississippi, is duly qualified to carry on its business as a foreign corporation under the laws of the State of Alabama and has due corporate authority to carry on the public utility business in which it is engaged, to own and operate the properties used by it in such business and to enter into and perform its obligations under the Agreements and the Notes.

4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, subject to the qualifications that the enforceability of the Company’s obligations under the Indenture may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); and the Indenture conforms as to legal matters in all material respects to the description thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriter pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); and the Notes conform as to legal matters in all material respects to the description thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

6. The Indenture has been duly qualified under the Trust Indenture Act.

We have not independently verified the accuracy, completeness or fairness of the statements made or included in the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and take no responsibility therefor, except as and to the extent set forth in paragraphs 4 and 5 above. In the course of the preparation by the Company of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we participated in conferences with certain officers and employees of the Company, with other counsel for the Company, with representatives of Deloitte & Touche LLP and with your counsel. Based upon our examination of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, our investigations made in connection with the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and our participation in the conferences

referred to above, (i) we are of the opinion that the Registration Statement, on the Effective Date, and the Final Supplemented Prospectus, as of November 14, 2008, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that the Exchange Act Documents, as of their respective dates of filing with the Commission, complied as to form in all material respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no opinion as to the financial statements or other financial or statistical data contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents, and (ii) nothing came to our attention which gives us reason to believe that (A) the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, (B) that the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (C) that the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement therein of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in each case we express no opinion or belief with respect to the financial statements or other financial or statistical data contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the caption “Description of the Series 2008A Senior Notes- Book-Entry Only Issuance - The Depository Trust Company.”

We are members of the State Bar of Mississippi and we do not express any opinion herein concerning any law other than the laws of the States of Alabama and Mississippi and, to the extent set forth herein, the laws of New York and the federal law of the United States.

This opinion is rendered to you in connection with the above-described transaction. This opinion may not be relied upon by you for any other purpose, or relied upon by or furnished to any other person without our prior written consent, except that Troutman Sanders LLP and Dewey & LeBoeuf LLP may rely on this opinion in giving their opinions pursuant to the Underwriting Agreement insofar as such opinions relate to matters of Mississippi and Alabama law.

Series 2008A 6.00% Senior Notes due November 15, 2013

Ladies and Gentlemen:

We have acted as counsel to Wells Fargo Bank, National Association (“Wells Fargo”), in connection with the issuance by Mississippi Power Company (the “Company”) of $50,000,000 aggregate principal amount of Series 2008A 6.00% Senior Notes due November 15, 2013 (the “Notes”). The Notes are being issued under the Senior Note Indenture dated as of May 1, 1998 (the “Original Indenture”) between the Company and Wells Fargo, as trustee (in such capacity, the “Trustee”), as supplemented by the Ninth Supplemental Indenture dated as of November 21, 2008 (the “Supplemental Indenture and, together with the Original Indenture, the “Indenture”) between the Company and the Trustee.

For purposes of this opinion, we have reviewed the Indenture and such other documents, records and papers, and satisfied ourselves as to such other matters, as we have deemed necessary or appropriate for this opinion. As to questions of fact material to this opinion, we have relied on certificates of Wells Fargo and of public officials. In such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies or forms and the authenticity of the originals of such latter documents. We have assumed that Wells Fargo has been duly formed and that the Indenture has been duly authorized, executed and delivered by the Company and constitutes the valid and binding agreement of, and is enforceable in accordance with its terms against, the Company.

Based upon the foregoing and subject to the qualifications below, we are of the opinion that:

1) Based solely on a certificate from the Comptroller of the Currency, Wells Fargo is a national banking association formed under the laws of the United States and is authorized thereunder to transact the business of banking and exercise fiduciary powers.

2) The Supplemental Indenture has been duly authorized, executed and delivered by Wells Fargo and the Indenture constitutes a valid and binding agreement of Wells Fargo enforceable against Wells Fargo in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and by an implied covenant of reasonableness, good faith and fair dealing.

We are members of the Bar of the State of New York and, for purposes of this opinion, do not hold ourselves out as experts on the laws of any jurisdiction other than the State of New York and the federal law of the United States. The opinions expressed herein are limited to matters governed by the laws of the State of New York and the federal law of the United States.

This opinion is solely for your benefit in connection with the issuance and sale by the Company of the Notes and may not be relied upon by you for any other purpose, or relied upon or furnished to any other person, without our prior written consent.

Very truly yours,

Schedule V

MISSISSIPPI POWER COMPANY

Series 2008A 6.00% Senior Notes

due November 15, 2013

Ladies and Gentlemen:

We have represented you in connection with (i) the issuance and sale by Mississippi Power Company (the “Company”) of $50,000,000 aggregate principal amount of its Series 2008A 6.00% Senior Notes due November 15, 2013 (the “Notes”) pursuant to a Senior Note Indenture dated as of May 1, 1998, by and between the Company and Wells Fargo Bank, National Association, as successor trustee (the “Trustee”), as heretofore supplemented and as further supplemented by the Ninth Supplemental Indenture, dated as of November 21, 2008 (collectively, the “Indenture”); and (ii) the purchase by you of the Notes pursuant to the terms of an Underwriting Agreement dated November 14, 2008 (the “Underwriting Agreement”), between the Company and you, as the Underwriter (the “Underwriter”). This opinion is being delivered to you pursuant to Section 6(c)(4) thereof.

All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.

In rendering the opinions expressed below, we have examined the registration statement on Form S-3 (No. 333-152895) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated September 8, 2008 (the “Basic Prospectus”) as supplemented by a preliminary prospectus supplement dated November 14, 2008 (the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act, which, pursuant to Form S-3, incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2007, the Quarterly Reports on Form 10-Q of the Company for the quarters ended March 31, 2008, June 30, 2008 and September 30, 2008 and the Current Reports on Form 8-K of the Company dated March 5, 2008 and October 8, 2008 (the “Pricing Exchange Act Documents”), and a prospectus supplement dated November 14, 2008 (together with the Basic Prospectus, the “Final

Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated November 14, 2008 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”); and the Indenture. We have also examined the free writing prospectus prepared by the Company and filed with the Commission on November 14, 2008 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”). The documents listed in Schedule II to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

The Indenture and the Underwriting Agreement are herein referred to as the “Agreements.”

Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion, relying as aforesaid and as to all matters covered hereby which are governed by or dependent upon the laws of the States of Mississippi and Alabama upon the opinion of Balch & Bingham LLP dated the date hereof and addressed to you, that:

3. All orders, consents or other authorizations or approvals of the Federal Energy Regulatory Commission and the Commission legally required for the issuance and sale of the Notes have been obtained; such orders are sufficient for the issuance and sale of the Notes; the issuance and sale of the Notes conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval of any Mississippi or United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of

any jurisdiction, as to which we express no opinion) is legally required for the issuance and sale of the Notes in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, subject to the qualifications that the enforceability of the Company's obligations under the Indenture may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); and the Indenture conforms as to legal matters in all material respects to the description thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriter pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company's obligations under the Notes may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); and the Notes conform as to legal matters in all material respects to the description thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

6. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

We have not independently verified the accuracy, completeness or fairness of the statements made or included in the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and take no responsibility therefor, except as and to the extent set forth in paragraphs 4 and 5 above. In the course of the preparation by the Company of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we participated in conferences with certain officers and employees of the Company, with representatives of Deloitte & Touche LLP and with counsel to the Company. Based upon our examination of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, our investigations made in connection with the preparation of the Registration Statement, the Pricing Disclosure Package and the Final Supplemented Prospectus and our participation in the conferences referred to above, (i) we are of the opinion that the Registration Statement, on the Effective Date and the Final Supplemented Prospectus, as of November 14, 2008, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that the Exchange Act Documents, as of their respective dates of filing with the Commission, complied as to form in all material

respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no opinion as to the financial statements or other financial or statistical data contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents, and (ii) nothing came to our attention which gives us reason to believe (A) that the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, (B) that the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (C) that the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in each case we express no opinion or belief with respect to the financial statements or other financial or statistical data contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the caption “Description of the Series 2008A Senior Notes - Book-Entry Only Issuance - The Depository Trust Company.”

We are members of the State Bar of New York and we do not express any opinion herein concerning any law other than the law of the State of New York and the federal law of the United States and, to the extent set forth herein, the laws of the States of Mississippi and Alabama.

This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent except that Balch & Bingham LLP and Troutman Sanders LLP may rely on this opinion in giving their opinions pursuant to Section 6 of the Underwriting Agreement insofar as such opinions relate to matters of New York law and Troutman Sanders LLP may rely on this opinion in giving its opinion pursuant to Sections 102, 302 and 904 of the Indenture, insofar as such opinion relates to matters of New York law.

Very truly yours,
