     contract,  indenture,  mortgage,  loan  agreement,  note,  lease  or  other
     agreement or  instrument to which the Company is a party or by which it may

     the transactions contemplated by this Agreement and the Deposit Agreement),
     or (B) any existing applicable law, rule,  regulation,  judgment,  order or
     decree of any government,  governmental  instrumentality or court, domestic

SECTION 2.        SALE AND DELIVERY TO THE UNDERWRITERS; CLOSING.
                  ----------------------------------------------

(a) On the basis of the representations and warranties herein contained and
subject to the terms and conditions herein set forth, the Company agrees to sell
to each Underwriter, and each Underwriter, severally and not jointly, agrees to
purchase from the Company, the respective number of Depositary Shares set forth
in Schedule I to this Agreement opposite the name of such Underwriter at a price
per Depositary Share of $24.50.

(b) Payment of the purchase price for the Depositary Shares and delivery of
certificates for the Depositary Shares shall be made at the offices of Troutman
Sanders LLP, Bank of America Plaza, 600 Peachtree Street, N.E., Suite 5200,
Atlanta, Georgia at 10:00 A.M., Atlanta time, on April 7, 2004 (unless postponed
in accordance with the provisions of Section 10 hereof) or such other time,
place or date as shall be agreed upon by the Underwriters and the Company (such
time and date of payment and delivery being herein called the "Closing Date").
Payment shall be made to the Company by wire transfer in federal funds at the
Closing Date against delivery of the Depositary Shares to Goldman, Sachs & Co.
It is understood that each Underwriter has authorized Goldman, Sachs & Co., for
each Underwriter's account, to accept delivery of, receipt for, and make payment
of the number of the Depositary Shares which each Underwriter has agreed to
purchase. Goldman, Sachs & Co., individually and not as a representative of the
Underwriters, may (but shall not be obligated to) make payment of the number of
the Depositary Shares to be purchased by any Underwriter whose payment has not
been received by the Closing Date, but such payment shall not relieve such
Underwriter from its obligations hereunder.

                  The delivery of the Depositary Shares shall be made in fully
registered form, registered in the name of CEDE & CO., to the offices of The
Depository Trust Company in New York, New York or its designee, and the
Underwriters shall accept such delivery.

                  The certificate(s) for the Depositary Shares will be made
available for examination by the Underwriters 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 Underwriters
as follows:

(a)  The  Company,  on or  prior  to  the  Closing  Date,  will  deliver  to the
     Underwriters  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 Underwriters  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 Underwriters
     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)  for   distribution   to  the
     Underwriters  and, from time to time, as many copies of the  Prospectus and
     the  Final  Supplemented  Prospectus  as the  Underwriters  may  reasonably
     request for the purposes contemplated by the 1933 Act or the 1934 Act.

(b)  The Company will furnish the Underwriters with copies of each amendment and
     supplement to the Final Supplemented Prospectus relating to the offering of
     the Depositary  Shares in such quantities as the Underwriters 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 Depositary  Shares by an  Underwriter,  any
     event  relating to or affecting the Company,  or of which the Company shall
     be  advised  in  writing by the  Underwriters,  shall  occur,  which in the
     opinion of the Company or of Underwriters' 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 the Prospectus
     in order to comply with the 1933 Act or the 1934 Act, the Company forthwith
     will (i) notify the  Underwriters  to suspend  solicitation of purchases of
     the  Depositary  Shares and (ii) at its  expense,  make any such  filing or
     prepare and furnish to the Underwriters 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 any Underwriter is required to deliver a prospectus in
     connection  with the sale of any Depositary  Shares after the expiration of
     the period  specified in the  preceding  sentence,  the  Company,  upon the
     request  of such  Underwriter,  will  furnish to such  Underwriter,  at the
     expense of such  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 Underwriters and Dewey Ballantine LLP.

(c)      The Company will endeavor, in cooperation with the Underwriters, to
         qualify the Preferred Stock and the Depositary Shares for offering and
         sale under the applicable securities laws of such states and the other
         jurisdictions of the United States as the Representative 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)      The Company will use its best efforts to effect the listing of the
         Depositary Shares on the New York Stock Exchange.

(f)      During a period of 15 days from the date of this Agreement, the Company
         will not, without the Underwriters' prior written consent, directly or
         indirectly, sell, offer to sell, grant any option for the sale of, or
         otherwise dispose of, any depositary shares or shares of preferred
         stock or any security convertible into or exchangeable into or
         exercisable for preferred stock of the Company or any securities
         substantially similar to the Depositary Shares or the Preferred Stock
         (except for the Depositary Shares or the Preferred Stock issued
         pursuant to this Agreement).

(g)      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 Underwriters of such filing and to confirm such advice in
         writing.

(h)      The Company will file in the office of the Secretary of State of
         Mississippi a charter amendment creating the Preferred Stock.

connection with the listing of the Depositary Shares on the New York Stock

                  Except as otherwise provided in Section 9 hereof, the

SECTION 5.  CONDITIONS OF  UNDERWRITERS'  OBLIGATIONS.  The  obligations  of the
Underwriters  to purchase and pay for the  Depositary  Shares 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  Underwriters  or  the  Company  (but  all
     provisions of such order or orders heretofore entered, copies of which have
     heretofore been delivered to the Underwriters, are deemed acceptable to the
     Underwriters  and the  Company and all  provisions  of such order or orders
     hereafter  entered shall be deemed  acceptable to the  Underwriters 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).

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

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

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

(3)      The opinion, dated the Closing Date, of Dewey Ballantine LLP, counsel
         for the Underwriters, substantially in the form attached hereto as
         Schedule 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
     Underwriters 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 have been  initiated  or, to the knowledge of
     the Company, threatened by the Commission.

(e)  On the Closing Date, the  Underwriters  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  Underwriters'  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 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,  if any, for  Operating  Revenues,
     Earnings  Before  Income Taxes and Net Income After  Dividends on Preferred
     Stock and the unaudited Ratios of Earnings to Fixed Charges and Earnings to
     Fixed Charges Plus Preferred Dividend Requirements  (Pre-Income Tax Basis),
     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  Ratios of Earnings to Fixed Charges and
     Earnings to Fixed Charges Plus Preferred Dividend Requirements  (Pre-Income
     Tax Basis) 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 Underwriters 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 Depositary Shares 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 Depositary Shares as herein contemplated
         shall be satisfactory in form and substance to the Underwriters and
         Dewey Ballantine LLP, counsel for the Underwriters.

(g)      On the Closing Date, the Depositary Shares shall have been approved for
         listing on the New York Stock Exchange upon notice of issuance.

(h)      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
         Underwriters) which, in the reasonable judgment of the Underwriters,
         shall materially impair the marketability of the Depositary Shares.

(i)      The Company shall have performed its obligations when and as provided
         under this Agreement and the Deposit 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 Underwriters 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
Underwriters. 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 each of the Underwriters
and each person, if any, who controls any such 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 any such 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 Underwriters any amendments or any supplements
thereto, or shall make any filings pursuant to Section 13 or 14 of the 1934 Act
which are incorporated by reference therein, 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 Final Supplemented Prospectus in reliance upon and in
conformity with information furnished in writing to the Company by, or through
the Underwriters on behalf of, any 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 any Underwriter (or of
any person controlling such Underwriter) on account of any losses, claims,
damages, liabilities or actions arising from the sale of the Depositary Shares
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 such
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. Each 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 such Underwriter so to notify the
Company of any such action shall not release the Company from any liability
which it may have to such 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 an Underwriter or any such person
controlling such Underwriter and such 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, any 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
such 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) Each Underwriter agrees, severally and not jointly, 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 such 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,
regardless of any investigation made by or on behalf of any Underwriter or
controlling person, or by, or on behalf of the Company and shall survive
delivery of the Depositary Shares to the Underwriters.

SECTION 9.        TERMINATION OF AGREEMENT.
                  ------------------------

(a) The Underwriters may terminate this Agreement, by notice to the Company, at
any time at or prior to the Closing Date if (i) 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 York State
authorities, or (iv) there shall have occurred any 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 judgment of the
Underwriters, the marketability of the Depositary Shares shall have been
materially impaired.

(b) If this Agreement shall be terminated by the Underwriters 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 Underwriters 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 Underwriters in making preparations for the
purchase, sale and delivery of the Depositary Shares and, upon such
reimbursement, the Company shall be absolved from any further liability
hereunder, except as provided in Sections 4 and 7.

SECTION 10.       DEFAULT BY ONE OR MORE OF THE UNDERWRITERS

                  If an Underwriter shall fail on the Closing Date to purchase
the Depositary Shares that it is obligated to purchase under this Agreement (the
"Defaulted Securities"), the Underwriters shall have the right, within 24 hours
thereafter, to make arrangements for the non-defaulting Underwriters, or any
other underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth. If, however, the Underwriters shall not have completed such arrangements
within such 24-hour period, then:

(a) if the principal amount of Defaulted Securities does not exceed 10% of the
Depositary Shares, the non-defaulting Underwriters shall be obligated, severally
and not jointly, to purchase the full amount thereof in the proportion that
their respective underwriting obligations hereunder bear to the underwriting
obligations of all non-defaulting Underwriters, or

(b) if the principal amount of Defaulted Securities exceeds 10% of the
Depositary Shares, this Agreement shall terminate without liability on the part
of any non-defaulting Underwriter.

                  No action taken pursuant to this Section shall relieve any
defaulting Underwriter from liability in respect of its default.

                  In the event of any such default which does not result in a
termination of this Agreement, either the Underwriters or the Company shall have
the right to postpone the Closing Date for a period not exceeding seven days in
order to effect any required changes in the Registration Statement or Final
Supplemented Prospectus or in any other documents or arrangements.

SECTION 11. NOTICES. All notices and other communications  hereunder shall be in
writing and shall be deemed to have been duly given if mailed or  transmitted by
any standard form of  telecommunication.  Notices to the  Underwriters  shall be

SECTION 12. PARTIES. This Agreement shall inure to the benefit of and be binding
upon the Underwriters, the Company and their respective successors. Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any person, firm or corporation, other than the Underwriters and the
Company and their respective successors and the controlling persons and officers
and directors referred to in Section 7 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision herein contained. This Agreement and
all conditions and provisions hereof are intended to be for the sole and
exclusive benefit of the Underwriters and the Company and their respective
successors, and said controlling persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm or

shall be deemed to be a successor by reason merely of such purchase.

construed in accordance with the laws of the State of New York applicable to
agreements made and to be performed in said State. Except as otherwise set forth
herein, specified times of day refer to New York City time.

SECTION 14. COUNTERPARTS. This Agreement may be executed by any one or more of
the parties hereto in any number of counterparts, each of which shall be deemed
to be an original, but all such respective counterparts shall together
constitute one and the same instrument.







                  If the foregoing is in accordance with your understanding of
our agreement, please sign and return to the Company a counterpart hereof,
whereupon this instrument, along with all counterparts, will become a binding

                                      Very truly yours,

                                      MISSISSIPPI POWER COMPANY

                            Par Value $100 Per Share

Ladies and Gentlemen:

                  We have acted as general counsel to Mississippi Power Company
(the "Company") in connection with the purchase by you of an aggregate of
1,200,000 Depositary Shares (the "Depositary Shares"), each representing
one-fourth of a share of 5.25% Series Preferred Stock, Cumulative, Par Value
$100 Per Share, of the Company (the "Preferred Stock") pursuant to the terms of
an Underwriting Agreement dated March 3, 2004 (the "Underwriting Agreement"),
among the Company and the underwriters named in Schedule I thereto (the
"Underwriters"). 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 Preferred Stock and the Depositary Shares and
certain other securities (the "Registration Statement") filed under the
Securities Act of 1933, as amended (the "Act"), and the prospectus of the
Company 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
Reports on Form 8-K of the Company dated ________, 2004 and _______, 2004 (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 Depositary Shares, 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, other than those of the Company,
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.

                  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; 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 Underwriting Agreement and the Deposit Agreement.

                  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 Preferred
Stock and the Depositary Shares have been obtained; such orders are sufficient
for the issuance and sale of the Preferred Stock and the Depositary Shares; the
issuance and sale of the Preferred Stock and the Depositary Shares 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 Preferred Stock
and the Depositary Shares in accordance with the terms of the Underwriting
Agreement.

                  4. The Deposit Agreement has been duly authorized, executed
and delivered by the Company and, assuming the due authorization, execution and
delivery thereof by the Depositary, 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 Deposit Agreement conforms as to legal matters in all material respects
to the description thereof in the Final Supplemented Prospectus.

                  5. The Preferred Stock and the Depositary Shares have been
duly authorized by the Company.

                  6. The Preferred Stock has been duly executed by the Company
and, upon payment and delivery in accordance with the Underwriting Agreement and
the Deposit Agreement, will be validly issued, fully-paid and non-assessable.

                  7. The Depositary Shares, assuming the due authorization,
execution and delivery by the Depositary of the Deposit Agreement and the due
authorization, execution and delivery by the Depositary of the Receipts in
accordance with the terms of the Deposit Agreement and upon the deposit by or on
behalf of the Underwriters of the Preferred Stock with the Depositary pursuant
to the Deposit Agreement, the Depositary Shares will represent legal and valid
interests in the Preferred Stock and the Receipts will constitute valid evidence
of such interests in the Preferred Stock and will be entitled to the benefits of
the Deposit Agreement.

                  8. The statements made in the Final Supplemented Prospectus
under the captions "Description of the New Stock," "Description of Depositary
Shares" and "Certain Terms of the New Stock and the Depositary Shares"
constitute accurate summaries of the terms of the articles of incorporation of
the Company, the Preferred Stock and the Depositary Shares in all material
respects.

                  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 8 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
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 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 Final Supplemented Prospectus or
the Exchange Act Documents and with respect to information set forth in the
Final Supplemented Prospectus under the caption "Certain Terms of the New Stock
and the Depositary Shares - Book-Entry Only Issuance - The Depository Trust
Company."

                  We are members of the State Bars of Mississippi and Alabama
and we do not express any opinion herein concerning any law other than the law
of such States and the federal law of the United States and, to the extent set
forth herein, the laws of the State of 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 Troutman Sanders LLP and Dewey Ballantine 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.

                  In addition, we have examined, and have relied as to matters
