                    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  consistent  with that of the
                    audited and unaudited financial  statements  incorporated by
                    reference in the Registration Statement.

               SECTION  2.  SALE  AND  DELIVERY  TO  THE  UNDERWRITER;  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  the
                    Underwriter, and the Underwriter agrees to purchase from the
                    Company, the Senior Notes at a price equal to 98.624% of the
                    principal amount thereof.

                    (b)  Payment  of  the   purchase   price  and   delivery  of
                    certificates  for  the  Senior  Notes  shall  be made at the
                    offices of Troutman Sanders LLP, 405 Lexington  Avenue,  New
                    York,  New York at 10:00  A.M.,  New York time,  on June 30,
                    2005 or such  other  time,  place or date as shall be agreed
                    upon by the  Underwriter 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  Senior  Notes  to the  Underwriter.  It is
                    understood  that the  Underwriter  will accept  delivery of,
                    receipt for, and make payment of the principal amount of the
                    Senior Notes which it has agreed to purchase.

                  The delivery of the Senior Notes 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
Underwriter shall accept such delivery.

                  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 the 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 the Underwriter
                    at the expense of the Underwriter,  a reasonable quantity of
                    a  supplemented  or amended  prospectus,  or  supplements or
                    amendments to the Final Supplemented  Prospectus,  complying
                    with  Section  10(a)  of the 1933  Act.  During  the  period
                    specified  in the second  sentence of this  subsection,  the
                    Company   will   continue  to  prepare  and  file  with  the
                    Commission  on a timely basis all  documents  or  amendments
                    required  under the 1934 Act and the  rules and  regulations
                    thereunder;  provided,  that the Company shall not file such
                    documents  or  amendments  without  also  furnishing  copies
                    thereof  prior to such filing to the  Underwriter  and Dewey
                    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,  the  Company  will  file  the  Final
                    Supplemented  Prospectus with the Commission and will advise
                    the  Underwriter of such filing and will 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 preparation, issuance and delivery of the certificate(s) for the
Senior Notes, (iii) the fees and disbursements of the Company's counsel and
accountants, (iv) the qualification of the Senior Notes under securities laws
in accordance with the provisions of Section 3(c) hereof, including filing fees
and the reasonable fees and disbursements of counsel for the Underwriter in
connection therewith and in connection with the preparation of any blue sky

the printing and delivery to the Underwriter of copies of the Registration
Statement as originally filed and of each amendment thereto and of the
Prospectus, the Final Supplemented Prospectus and any amendments or supplements
thereto, (vi) the printing and delivery to the Underwriter of copies of any blue
sky survey, (vii) the fee of the National Association of Securities Dealers,
Inc. in connection with its review of the offering contemplated by this
Agreement, if applicable, (viii) the fees and expenses of the Trustee,
including the fees and disbursements of counsel for the Trustee in connection
with the Indenture and the Senior Notes, (ix) any fees payable in connection
with the rating of the Senior Notes, (x) the cost and charges of any transfer
agent or registrar and (xi) the cost of qualifying the Senior Notes with The
Depository Trust Company.

                  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, copies of which
         shall be delivered to the Underwriter prior to the Closing Date, 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,  substantially in the
                    form attached hereto as Schedule I-A.

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

                    (3) The  opinion,  dated the Closing  Date,  of White & Case
                    LLP,  counsel  to the  Trustee,  substantially  in the  form
                    attached hereto as Schedule II.

                    (4) The opinion, dated the Closing Date, of Dewey Ballantine
                    LLP, counsel for the Underwriter,  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 notarising in the  ordinary
          course  of  business,  and  the  Underwriter shall have received  a
          certificate of the President or any Vice President of the Company, and
          dated as of the Closing Date, to the effect that (i) there has been no
          such material adverse change,  (ii) the representations and warranties
          in  Section  1 hereof  are true and  correct  with the same force and
          effect as though  expressly made at and as of the Closing Date,  (iii)
          the  Company  has  complied  with all  agreements  and  satisfied  all
          conditions on its part to be performed or satisfied on or prior to the
          Closing Date, and (iv) no stop order  suspending the effectiveness of
          the Registration Statement has been issued and no proceedings for that
          purpose  have been  initiated  or, to the  knowledge 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 an independent registered public accounting firm with respect
          to the  Company  within the  meaning of the 1933 Act and the rules and
          regulations  under the 1933 Act; (B) in their  opinion,  the financial
          statements  audited by them and incorporated by reference in the 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 standards of the Public Company Accounting
          Oversight  Board  (United  States)  ("PCAOB")  for a review of interim
          financial  statement  information  as described  in SAS 100,  "Interim
          Financial Information", on the unaudited financial statements, if any,
          of the Company  incorporated  by reference  in the Final  Supplemented
          Prospectus and on the latest available unaudited financial  statements
          of the Company,  if any, for any calendar  quarter  subsequent  to the
          date of those  incorporated  by  reference  in the 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 for Operating Revenues, Earnings Before Income Taxes
          and Net Income After  Dividends on Preferred  Stock and the  unaudited
          Ratio of Earnings to Fixed Charges set forth in the 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  unaudited  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 for any calendar quarter subsequent
          to those set forth in (3) above,  which,  if  available,  shall be set
          forth in such  letter,  do not agree with the  amounts set forth in or
          derived from the unaudited financial statements for the same period or
          were not determined on a basis  substantially  consistent with that of
          the  corresponding  audited amounts or ratios included or incorporated
          by reference in the 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 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 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,
regardless of any investigation made by or on behalf of the Underwriter or
controlling person, or by, or on behalf of the Company and shall survive
delivery of the Senior Notes to the Underwriter.

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

(a) The Underwriter 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

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

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
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, upon such reimbursement,
the Company shall be absolved from any further liability hereunder, except as
provided in Sections 4 and 7.

                           Series G ___% Senior Notes
                                due July 1, 2035

Ladies and Gentlemen:

                  We have acted as general counsel to Mississippi Power Company
(the "Company") in connection with (i) the Company's issuance of $30,000,000
aggregate principal amount of its Series G ___% Senior Notes due July 1, 2035
(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
Seventh Supplemental Indenture dated as of June 30, 2005 (collectively, the
"Indenture"); and (ii) the purchase by you of the Notes pursuant to the terms of
an Underwriting Agreement dated June 24, 2005 (the "Underwriting Agreement"),
between the Company and you (the "Underwriter"). This opinion is being delivered
to you pursuant to Section 5(c)(1) thereof.

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

                  In rendering the opinions expressed below, we have examined
the registration statement on Form S-3 (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 of the Company dated September 3, 2003 as
supplemented by a final prospectus supplement dated June __, 2005 (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, 2004 (the "Form 10-K"), the Quarterly Report on Form 10-Q of the Company for
the quarter ended March 31, 2005 and the Current Reports on Form 8-K of the
Company dated January 3, 2005, February 21, 2005, May 5, 2005 and June __, 2005
(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, 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.

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

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

                  Based upon the foregoing, and subject to the qualifications
and limitations stated herein, we are of the opinion, relying as to matters of
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. The Indenture has been duly authorized, executed and
delivered by the Company and, assuming the due authorization, execution and
delivery thereof by the Trustee, constitutes a valid and legally binding
instrument of the Company, enforceable against the Company in accordance with
its terms, subject to the qualifications that the enforceability of the
Company's obligations 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.

                  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 June __, 2005, 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 Exchange Act Documents on file with the Commission as of
such date), contained any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary in order to
make the statements therein not misleading, 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 "Description of the Series G Senior
Notes - Book-Entry Only Issuance - The Depository Trust Company".

                  We are members of the State Bar of Mississippi and we do not
express any opinion herein concerning any law other than the law of such State
and the federal law of the United States and, to the extent set forth herein,
the laws of the States of Alabama 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 Troutman Sanders LLP and Dewey Ballantine LLP
may rely on this opinion in giving their opinions pursuant to the Underwriting
Agreement insofar as such opinion relates to matters of Mississippi and Alabama
law.

                                                     Yours very truly,



                                                     BALCH & BINGHAM LLP

Ladies and Gentlemen:

                  We have acted as counsel to Mississippi Power Company (the
"Company") in connection with (i) the Company's issuance of $30,000,000
aggregate principal amount of its Series G ___% Senior Notes due July 1, 2035
(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

                  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

31, 2004 (the "Form 10-K"), the Quarterly Report on Form 10-Q of the Company for
the quarter ended March 31, 2005 and the Current Reports on Form 8-K of the
Company dated January 3, 2005, February 21, 2005, May 5, 2005 and June __, 2005
(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, 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.

                  The Indenture 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. The Indenture has been duly authorized, executed and
delivered by the Company and, assuming the due authorization, execution and
delivery thereof by the Trustee, constitutes a valid and legally binding
instrument of the Company, enforceable against the Company in accordance with
its terms, subject to the qualifications that the enforceability of the
Company's obligations 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 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 June __, 2005, 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 Exchange Act Documents on file with the Commission as of
such date), contained any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary in order to
make the statements therein not misleading, 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 G 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

                            Mississippi Power Company
                   Series G ___% Senior Notes due July 1, 2035

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 Seventh Supplemental Indenture
to the Original Indenture, dated as of June 30, 2005 (together with the Original
Indenture, herein called the "Indenture"), between the Company and the Trustee
with respect to the issuance by the Company of $30,000,000 aggregate principal
amount of Series G ___% Senior Notes due July 1, 2035 (the "Series G Senior
Notes").

         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 has been duly authorized, executed and delivered by
the Bank and 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 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 G Senior 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
performance by the Bank of the terms of the Indenture.

         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,




                                                     WHITE & CASE LLP

                                due July 1, 2035

Ladies and Gentlemen:

                  We have represented you in connection with (i) the issuance by
Mississippi Power Company (the "Company") of $30,000,000 aggregate principal
amount of its Series G ___% Senior Notes (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
Seventh Supplemental Indenture dated as of June 30, 2005 (collectively, the
"Indenture"); and (ii) the purchase by you of the Notes pursuant to the terms of
an Underwriting Agreement dated June 24, 2005 (the "Underwriting Agreement"),
between the Company and you (the "Underwriter"). This opinion is being delivered
to you pursuant to Section 5(c)(4) 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 June __, 2005 (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, 2004
(the "Form 10-K"), the Quarterly Report on Form 10-Q of the Company for the
quarter ended March 31, 2005 and the Current Reports on Form 8-K of the Company,
dated January 3, 2005, February 21, 2005, May 5, 2005 and June __, 2005 (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 and the Underwriting Agreement are herein
referred to as the "Agreements".

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

                  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
approval of any New York, Mississippi or United States governmental body (other
than in connection or in compliance with the provisions of the securities or
"blue sky" laws of any jurisdiction, as to which we express no opinion) is
legally required for the issuance and sale of the Notes in accordance with the
terms of the Underwriting Agreement.

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

                  5. The Notes have been duly authorized and executed by the

                  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
