                  operations and cash flows of the Company as of and for the
                  dates indicated; said financial statements have been prepared
                  in conformity with accounting principles generally accepted in
                  the United States ("GAAP") applied on a consistent basis
                  (except that the unaudited financial statements may be subject
                  to normal year-end adjustments) throughout the periods
                  involved and necessarily include amounts that are based on the
                  best estimates and judgments of management. The selected
                  financial data and the summary financial information included
                  in the Final Supplemented Prospectus present fairly the
                  information shown therein and have been compiled on a basis

                  statements incorporated by reference in the Registration
                  Statement.

                  The certificate(s) for the Senior Notes will be made available
for examination by the Underwriter not later than 12:00 Noon, New York time, on
the last business day prior to the Closing Date.

SECTION 3. 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 therefor, 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 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 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 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 shall be required by law in
                  connection with the sale of any Senior Notes by an
                  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 in order to make the Final Supplemented Prospectus
                  not misleading in the light of the circumstances when it 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 Preliminary
                  Prospectus or 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 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 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 Ballantine 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)      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 3(e).

         (f)      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, to file the Final Supplemented Prospectus with the
                  Commission and to advise the Underwriter of such filing and to
                  confirm such advice in writing.

SECTION 4. PAYMENT OF EXPENSES. 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

the qualification of the Senior Notes under securities laws in accordance with
the provisions of Section 3(c) hereof, including filing fees and the reasonable

and in connection with the preparation of any blue sky survey (such fees and

(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.

                  Except as otherwise provided in Section 9 hereof, the
Underwriter shall pay all other expenses incurred by it in connection with its
offering of the Senior Notes including fees and disbursements of its counsel,
Dewey Ballantine LLP.

SECTION 5. CONDITIONS OF UNDERWRITER'S OBLIGATIONS. The obligations of the
Underwriter to purchase and pay for the Senior Notes are subject to the
following conditions:

         (a)      No stop order suspending the effectiveness of the Registration
                  Statement shall be in effect on the Closing Date and no
                  proceedings for that purpose shall be pending before, or to
                  the knowledge of the Company threatened by, the Commission on
                  such date. If filing of the Final Supplemented Prospectus, or
                  any supplement thereto, is required pursuant to Rule 424, the
                  Final Supplemented Prospectus, and any such supplement, shall
                  have been filed in the manner and within the time period
                  required by Rule 424.

         (b)      Any required orders of 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 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 party to the effect that such
                  order contains an unacceptable provision).

         (c)      On the Closing Date, the Underwriter shall have received:

                  (1)      The opinion, dated the Closing Date, of Balch &
                           Bingham LLP, general counsel for the Company,

                           III.

         (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

                  (iv) no stop order suspending the effectiveness of the

                  Company, threatened by the Commission.

         (e)      On the Closing Date, the Underwriter shall have received from
                  Deloitte & Touche LLP a letter dated the Closing Date to the
                  effect that: (A) they are independent certified public
                  accountants 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 Final Supplemented
                  Prospectus 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 five 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
                  American Institute of Certified Public Accountants for a
                  review of interim financial information as described in
                  Statement on Auditing Standards No. 71, "Interim Financial
                  Information" and in Statement on Auditing Standards No. 100,
                  "Interim Financial Information", as applicable, on the
                  unaudited financial statements, if any, of the Company
                  incorporated by reference in the Final Supplemented Prospectus
                  and of 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 Final
                  Supplemented Prospectus; 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 Final Supplemented Prospectus, for them to be
                  in conformity with generally accepted accounting principles;
                  (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, if any, for Operating
                  Revenues, Earnings Before Income Taxes and Net Income After
                  Dividends on Preferred Stock and the unaudited Ratio of
                  Earnings to Fixed Charges, if any, set forth in the Final
                  Supplemented Prospectus 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 five 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 balance sheet
                  incorporated by reference in the Final Supplemented
                  Prospectus, except in each case for changes or decreases which
                  (i) the Final Supplemented Prospectus discloses have occurred
                  or may occur, (ii) are occasioned by the declaration of
                  dividends, (iii) are occasioned by draw-downs and regularly
                  scheduled payments of capitalized lease obligations, (iv) are
                  occasioned by the purchase or redemption of bonds or stock to
                  satisfy mandatory or optional redemption provisions relating
                  thereto, (v) are occasioned by reclassification of current
                  maturities of long-term debt or (vi) 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 as of the end of 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 Final Supplemented Prospectus.

         (f)      On the Closing Date, 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 Ballantine 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 Ballantine 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 4, 7 and 9(b) hereof.

SECTION 6. 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 5(a) and in Section 5(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 4, 7 and 9(b) hereof.

SECTION 7. INDEMNIFICATION.

         (a)      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,
                  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 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 Prospectus or the
                  Final Supplemented Prospectus as so amended or supplemented,
                  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, Prospectus or the Final
                  Supplemented Prospectus in reliance upon and in conformity
                  with information furnished in writing to the Company by the
                  Underwriter for use therein and except that this indemnity
                  with respect to the Preliminary Prospectus, the Prospectus or
                  the Final Supplemented Prospectus, if the Company shall have
                  furnished any amendment or supplement thereto, shall not inure
                  to the benefit of the Underwriter (or of any person
                  controlling the Underwriter) on account of any losses, claims,
                  damages, liabilities or actions arising from the sale of the
                  Senior Notes to any person if a copy of the Preliminary
                  Prospectus, the Prospectus or the Final Supplemented
                  Prospectus (exclusive of documents incorporated therein by
                  reference pursuant to Item 12 of Form S-3), as the same may
                  then be amended or supplemented, shall not have been sent or
                  given by or on behalf of the Underwriter to such person with
                  or prior to the written confirmation of the sale involved and
                  the untrue statement or alleged untrue statement or omission
                  or alleged omission was corrected in the Preliminary
                  Prospectus, the Prospectus or the Final Supplemented
                  Prospectus as supplemented or amended at the time of such
                  confirmation. 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 7, 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 7. 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.

         (b)      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 7(a) hereof, but only with
                  respect to alleged untrue statements or omissions made in the
                  Registration Statement, the Preliminary Prospectus, the
                  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 8. 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,

         (a)      The Underwriter may terminate this Agreement, by notice to the

                  trading in securities on the New York Stock Exchange shall
                  have been generally suspended or there shall have been a
                  material disruption in settlement of securities generally,
                  (ii) minimum or maximum ranges for prices shall have been
                  generally established on the New York Stock Exchange by the
                  Commission or by the New York Stock Exchange, (iii) a general
                  banking moratorium shall have been declared by federal or New

                  outbreak or escalation of major hostilities in which the
                  United States is involved, any declaration of war by the
                  United States Congress or any other substantial national or
                  international calamity, crisis or emergency (including,
                  without limitation, acts of terrorism) affecting the United
                  States, in any such case provided for in clauses (i) through
                  (iv) with the result that, in the reasonable judgement of the
                  Underwriter, the marketability of the Senior Notes shall have
                  been materially impaired.

         (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 Ballantine 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,

                            MISSISSIPPI POWER COMPANY
                       Series F Floating Rate Senior Notes
                                due March 9, 2009

Ladies and Gentlemen:

                  We have acted as general counsel to Mississippi Power Company
(the "Company") in connection with (i) the Company's issuance of $40,000,000
aggregate principal amount of its Series F Floating Rate Senior Notes due March
9, 2009 (the "Notes") pursuant to a Senior Note Indenture dated as of May 1,
1998, by and between the Company and Deutsche Bank Trust Company Americas
(formerly known as Bankers Trust Company), as trustee (the "Trustee"), as
supplemented by the Sixth Supplemental Indenture dated as of March 9, 2004
(collectively, the "Indenture"); and (ii) the purchase by you (the
"Underwriter") of the Notes pursuant to the terms of an Underwriting Agreement
dated March 3, 2004 (the "Underwriting Agreement"), between the Company and the
Underwriter. Pursuant to a Calculation Agent Agreement, dated as of March 9,
2004 (the "Calculation Agent Agreement"), between the Company and Deutsche Bank
Trust Company Americas, as calculation agent thereunder (the "Calculation
Agent"), the Company has engaged the Calculation Agent to perform certain
services with respect to the floating interest rate on the Notes. This opinion
is being delivered to you pursuant to Section 5(c)(1) of the Underwriting
Agreement.

                  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 (Nos. 333-108156, 333-108156-01 and
333-108156-02) pertaining to the Notes (the "Registration Statement") filed
under the Securities Act of 1933, as amended (the "Act"), and the prospectus
dated September 3, 2003, as supplemented by a final prospectus supplement dated
March 3, 2004 (the "Final Supplemented Prospectus"), 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, 2003 (the "Form 10-K") and the Current Report on
Form 8-K of the Company dated __________ (the "Exchange Act Documents"), each as
filed under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").

                  In addition, we have examined, and have relied as to matters
of fact upon, the documents delivered to you at the closing (except 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, the Calculation Agent Agreement 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, 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
New York law upon the opinion dated the date hereof rendered to you by Dewey
Ballantine 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.

         2. The execution, delivery and performance by the Company of the
Underwriting Agreement have been duly authorized by all necessary corporate
action, and the Underwriting Agreement has been duly executed and delivered by
the Company.

         3. All orders, consents or other authorizations or approvals of the
Commission legally required for the issuance and sale of the Notes have been
obtained; such orders are sufficient for the issuance and the sale of the Notes;
the issuance and the 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. Each of the Calculation Agent Agreement and the Indenture has been
duly authorized, executed and delivered by the Company and, assuming the due
authorization, execution and delivery thereof by the Calculation Agent and the
Trustee, respectively, 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
thereunder 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
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 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 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 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 your counsel and with representatives
of Deloitte & Touche LLP. Based upon our examination of the Registration
Statement, the Final Supplemented Prospectus and the Exchange Act Documents, our
investigations made in connection with the preparation of the Registration
Statement, 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, as of its effective date, and the Final
Supplemented Prospectus, as of March 3, 2004, complied as to form in all
material respects with the 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

                            MISSISSIPPI POWER COMPANY
                       Series F Floating Rate Senior Notes
                                due March 9, 2009

Ladies and Gentlemen:

                  We have acted as counsel to Mississippi Power Company (the
"Company") in connection with (i) the Company's issuance of $40,000,000
aggregate principal amount of its Series F Floating Rate Senior Notes due March
9, 2009 (the "Notes") pursuant to a Senior Note Indenture dated as of May 1,
1998, by and between the Company and Deutsche Bank Trust Company Americas
(formerly known as Bankers Trust Company), as trustee (the "Trustee"), as
heretofore supplemented and as further supplemented by the Sixth Supplemental
Indenture dated as of March 9, 2004 (collectively, the "Indenture"); and (ii)
the purchase by you of the Notes pursuant to the terms of an Underwriting
Agreement dated March 3, 2004 (the "Underwriting Agreement"), between the
Company and you (the "Underwriter"). Pursuant to a Calculation Agent Agreement,
dated as of March 9, 2004 (the "Calculation Agent Agreement"), between the
Company and Deutsche Bank Trust Company Americas, as calculation agent
thereunder (the "Calculation Agent"), the Company has engaged the Calculation
Agent to perform certain services with respect to the floating interest rate on
the Notes. This opinion is being delivered to you pursuant to Section 5(c)(2) of
the Underwriting Agreement.

                  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 (Nos. 333-108156, 333-108156-01 and
333-108156-02) pertaining to the Notes and certain other securities (the
"Registration Statement") filed under the Securities Act of 1933, as amended
(the "Act"), and the prospectus dated September 3, 2003, as supplemented by a
final prospectus supplement dated March 3, 2004 (the "Final Supplemented
Prospectus"), 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, 2003
(the "Form 10-K") and the Current Report on Form 8-K of the Company dated
_________ (the "Exchange Act Documents"), each as filed under the Securities
Exchange Act of 1934, as amended (the "Exchange Act").

                  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, the Calculation Agent Agreement and the
Underwriting Agreement are herein referred to collectively as the "Agreements".

                  Based upon the foregoing, and subject to the qualifications
and limitations stated herein, we are of the opinion, relying as to matters of
Mississippi and Alabama law upon the opinion dated the date hereof rendered to
you by Balch & Bingham LLP and relying as to matters of New York law upon the
opinion dated the date hereof rendered to you by Dewey Ballantine LLP, that:

         1. The Company has been duly incorporated and is validly existing as a
corporation in good standing 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.

         2. The execution, delivery and performance by the Company of the
Underwriting Agreement have been duly authorized by all necessary corporate
action, and the Underwriting Agreement has been duly executed and delivered by
the Company.

         3. All orders, consents or other authorizations or approvals of 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. Each of the Calculation Agent Agreement and the Indenture has been
duly authorized, executed and delivered by the Company and, assuming the due
authorization, execution and delivery thereof by the Calculation Agent and the
Trustee, respectively, 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
Calculation Agent Agreement and the Indenture conforms as to legal matters in
all material respects to the description thereof in 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 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 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 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 Final Supplemented Prospectus and the Exchange Act Documents, our
investigations made in connection with the preparation of the Registration
Statement, 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, as of its effective date, and the Final
Supplemented Prospectus, as of March 3, 2004, complied as to form in all
material respects with the 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 Final Supplemented Prospectus or the Exchange Act
Documents, and (ii) nothing came to our attention which gives us reason to
believe that the Registration Statement, as of the date of filing of the Form
10-K (including the Form 10-K), 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, or 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 Final Supplemented Prospectus or
the Exchange Act Documents and with respect to information set forth in the
Final Supplemented Prospectus under the caption "Description of the Series F
Senior Notes - Book-Entry Only Issuance - The Depository Trust Company".

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

                  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 Balch & Bingham LLP may rely on this opinion
in giving its opinion pursuant to Section 5(c) of the Underwriting Agreement,
insofar as such opinion relates to matters of federal securities law.

                                                     Yours very truly,

                            Mississippi Power Company
              Series F Floating Rate Senior Notes due March 9, 2009

Ladies and Gentlemen:

                  We have acted as counsel to Deutsche Bank Trust Company
Americas (formerly known as Bankers Trust Company), (the "Bank") in connection
with (a) the Senior Note Indenture, dated as of May 1, 1998, as heretofore
supplemented (the "Original Indenture"), between Mississippi Power Company (the
"Company") and the Bank, as Trustee, and (b) the Sixth Supplemental Indenture to
the Original Indenture, dated as of March 9, 2004 (together with the Original
Indenture, herein called the "Indenture"), between the Company and the Trustee
and (c) the Calculation Agent Agreement, dated as of March 9, 2004 (the
"Calculation Agent Agreement"), between the Company and the Bank, as Calculation
Agent, with respect to the issuance by the Company of $40,000,000 aggregate
principal amount of Series F Floating Rate Senior Notes due March 9, 2009.

         In this connection, we have examined such certificates of public
officials, such certificates of officers of the Bank, and copies certified to
our satisfaction of such corporate documents and records of the Bank, and of
such other papers, as we have deemed relevant and necessary for our opinion
hereinafter set forth. We have relied upon such certificates of public officials
and of officers of the Bank with respect to the accuracy of material factual
matters contained therein which were not independently established. In rendering
the opinion expressed below, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals and the
conformity to authentic original documents of all documents submitted to us as
certified, conformed or photostatic copies.

         Based upon the foregoing, it is our opinion that:

         1. The Bank has been duly incorporated and is validly existing as a New
York banking corporation under the laws of the State of New York and has the
power and authority to enter into, and to take all action required of it under,
the Indenture.

         2. The Indenture and the Calculation Agent Agreement have been duly
authorized, executed and delivered by the Bank and each constitutes a legal,
valid and binding obligation of the Bank, enforceable against the Bank in
accordance with its terms, except as the enforceability thereof may be limited
by (i) bankruptcy, insolvency, reorganization, or other similar laws affecting
the enforcement of creditors' rights generally, as such laws would apply in the
event of a bankruptcy, insolvency or reorganization or similar occurrence
affecting the Bank, and (ii) general principles of equity (regardless of whether
such enforceability is considered in a proceeding in equity or at law).

         3. The execution and delivery of the Indenture and the Calculation
Agent Agreement by the Bank and the performance by the Bank of its terms do not
conflict with or result in a violation of (A) any law or regulation of the
United States of America or the State of New York governing the banking or trust
powers of the Bank, or (B) the By-laws of the Bank.

         4. The Series F Notes have been duly authenticated and delivered by the
Bank.

         5. No approval, authorization or other action by, or filing with, any
governmental authority of the United States of America or the State of New York
having jurisdiction over the banking or trust powers of the Bank is required in
connection with the execution and delivery by the Bank of the Indenture or the
Calculation Agent Agreement or the performance by the Bank of the terms of the
Indenture or the Calculation Agent Agreement.

         We express no opinion as to matters governed by any law other than the
law of the State of New York and the Federal law of the United States.

                                                     Very truly yours,

                  In rendering the opinions expressed below, we have examined
the registration statement on Form S-3 (Nos. 333-108156, 333-108156-01 and

                  The Indenture, the Calculation Agent Agreement and the

                  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:

                  1. The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the State of
Mississippi, is duly qualified to carry on its business as a foreign corporation
in 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.

                  2. The execution, delivery and performance by the Company of
the Underwriting Agreement have been duly authorized by all necessary corporate
action, and the Underwriting Agreement has been duly executed and delivered by
the Company.

                  3. All orders, consents or other authorizations or approvals
of 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

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. Each of the Indenture and the Calculation Agent Agreement
has been duly authorized, executed and delivered by the Company and, assuming
the due authorization, execution and delivery thereof by the Trustee and the
Calculation Agent, respectively, 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 and the Calculation Agent Agreement
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 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

                  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 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 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 Final Supplemented

with the preparation of the Registration Statement and the Final Supplemented
Prospectus and our participation in the conferences referred to above, (i) we
are of the opinion that the Registration Statement, as of its effective date,

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 Final Supplemented Prospectus or
the Exchange Act Documents, and (ii) nothing came to our attention which gives
us reason to believe that the Registration Statement, as of the date of filing
of the Form 10-K (including the Form 10-K), 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, or
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 Final Supplemented Prospectus or
