     information furnished in writing to the Company by the Underwriters through

(l)  The execution,  delivery and  performance by the Company of this Agreement,
     the Indenture and the Senior Notes and the  consummation  by the Company of
     the  transactions  contemplated  herein and therein and  compliance  by the
     Company with its obligations  hereunder and thereunder shall have been duly
     authorized by all necessary corporate action on the part of the Company and
     do not and will not result in any violation of the charter or bylaws of the
     Company,  and do not and will not conflict  with,  or result in a breach of


                                       5


     any of the terms or provisions of, or constitute a default under, or result

     the Company or materially adverse to the transactions  contemplated by this
     Agreement), or (B) any existing applicable law, rule, regulation, judgment,
     order or decree of any government,  governmental  instrumentality or court,
     domestic or foreign,  or any regulatory  body or  administrative  agency or
     other governmental body having jurisdiction over the Company, or any of its
     properties.

(m)      No authorization, approval, consent or order of any court or
         governmental authority or agency is necessary in connection with the
         issuance and sale by the Company of the Senior Notes or the
         transactions by the Company contemplated in this Agreement, except (A)
         such as may be required under the Securities Act or the rules and
         regulations thereunder; (B) such as may be required under the Federal
         Power Act; (C) such consents, approvals, authorizations, registrations
         or qualifications as may be required under state securities or "blue
         sky" laws and (D) the qualification of the Indenture under the 1939
         Act.

(n)  The  financial  statements  incorporated  by reference in the  Registration
     Statement,  the Pricing Prospectus and the Final  Supplemented  Prospectus,
     together  with the related  schedules  and notes,  present  fairly,  in all
     material respects,  the financial position,  results of operations and cash
     flows of the  Company  as of and for the dates  indicated;  said  financial
     statements  have been prepared in  conformity  with  accounting  principles
     generally  accepted in the United States  ("GAAP")  applied on a consistent
     basis (except that the  unaudited  financial  statements  may be subject to
     normal  year  end   adjustments)   throughout  the  periods   involved  and
     necessarily  include  amounts  that are  based on the  best  estimates  and
     judgments  of  management.  The  selected  financial  data and the  summary
     financial  information  included  in the Pricing  Prospectus  and the Final
     Supplemented  Prospectus  present fairly the information  shown therein and
     have been  compiled  on a basis  consistent  with that of the  audited  and

     Registration Statement.

subject to the terms and conditions herein set forth, the Company agrees to sell
to each Underwriter, severally and not jointly, and each Underwriter, severally
and not jointly, agrees to purchase from the Company, the principal amount of
the Senior Notes set forth in Schedule I to this Agreement opposite the name of
such Underwriter (plus any additional amount of the Senior Notes that such
Underwriter may become obligated to purchase pursuant to the provisions of

                                       6


Section 11 hereof), at a price equal to 99.125% of the principal amount thereof.

(b) Payment for and delivery of certificates for the Senior Notes shall be made
at the offices of Balch & Bingham LLP, 30 Allen Place, Suite 700, 30 Ivan Allen,

and the Company (such time and date of payment and delivery being herein called

Brothers Inc. It is understood that each Underwriter has authorized Lehman
Brothers Inc., for each Underwriter's account, to accept delivery of, receipt
for, and make payment of, the principal amount of the Senior Notes which each
Underwriter has agreed to purchase. Lehman Brothers Inc., individually and not
as a representative of the Underwriters, may (but shall not be obligated to)
make payment of the principal amount of the Senior Notes 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 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
Underwriters shall accept such delivery.

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

SECTION 3.        FREE WRITING PROSPECTUSES.

(a)  The Company  represents  and agrees that,  without the prior consent of the
     Representatives,  it has not made and will not make any offer  relating  to
     the Senior  Notes that would  constitute  a "free  writing  prospectus"  as
     defined in Rule 405 under the  Securities  Act, other than a Permitted Free
     Writing Prospectus; each Underwriter, severally and not jointly, represents
     and  agrees  that,  without  the  prior  consent  of the  Company  and  the
     Representatives,  it has not made and will not make any offer  relating  to
     the Senior  Notes that would  constitute  a "free  writing  prospectus"  as
     defined in Rule 405 under the Act,  other  than a  Permitted  Free  Writing
     Prospectus or a free writing prospectus that is not required to be filed by
     the Company pursuant to Rule 433; any such free writing  prospectus  (which
     shall include the pricing term sheet discussed in Section 3(b) hereof), the
     use of which has been consented to by the Company and the  Representatives,
     is listed on  Schedule  III and herein  called a  "Permitted  Free  Writing
     Prospectus."

(b)  The Company agrees to prepare a pricing term sheet, substantially in
     the form of Schedule II hereto and approved by the Representatives, and
     to file such pricing term sheet pursuant to Rule 433(d) under the
     Securities Act within the time period prescribed by such Rule.

                                       7


(c)  The Company and the Representatives have complied and will comply with
     the requirements of Rule 433 under the Securities Act applicable to any
     free writing prospectus, including timely Commission filing where
     required and legending.

(d)  The Company  agrees that if at any time  following  issuance of a Permitted
     Free Writing  Prospectus  any event occurred or occurs as a result of which
     such Permitted Free Writing  Prospectus would conflict with the information
     in  the  Registration  Statement,  the  Pricing  Prospectus  or  the  Final
     Supplemented  Prospectus or include an untrue  statement of a material fact
     or omit  to  state  any  material  fact  necessary  in  order  to make  the
     statements  therein,  in light of the  circumstances  then prevailing,  not
     misleading,   the  Company   will  give  prompt   notice   thereof  to  the
     Representatives and, if requested by the Representatives,  will prepare and
     furnish  without  charge to each  Underwriter a free writing  prospectus or
     other   document,   the  use  of  which  has  been   consented  to  by  the
     Representatives,  which will correct such conflict,  statement or omission;
     provided, however, that this representation and warranty shall not apply to
     any statements or omissions in a Permitted Free Writing  Prospectus made in
     reliance upon and in conformity  with  information  furnished in writing to
     the Company by an Underwriter  through the  Representatives,  expressly for
     use therein.

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

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

     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

     proceedings  for that  purpose or pursuant to Section 8A of the  Securities
     Act against the  Company or related to the  offering,  of which the Company
     shall have  received  notice,  and will use its best efforts to prevent the
     issuance of any such stop order and to secure the prompt  removal  thereof,
     if issued.  The  Company  will  deliver to the  Representatives  sufficient
     conformed copies of the Registration Statement,  the Basic Prospectus,  the
     Pricing  Prospectus  and  the  Final  Supplemented  Prospectus  and  of all
     supplements  and  amendments  thereto (in each case without  exhibits)  for
     distribution to the Underwriters and, from time to

                                       8



     time, as many copies of the Basic  Prospectus,  the Pricing  Prospectus
     and the Final  Supplemented Prospectus as the Underwriters may reasonably
     request for the purposes contemplated by the Securities Act or the
     Exchange Act.

(b)  The Company will furnish the Underwriters with written or electronic copies
     of each  amendment  and  supplement  to the Final  Supplemented  Prospectus
     relating to the  offering  of the Senior  Notes in such  quantities  as the
     Underwriters  may from time to time  reasonably  request.  If,  during  the
     period (not exceeding nine months) when the delivery of a prospectus (or in
     lieu thereof,  the notice  referred to in Rule 173(a) under the  Securities
     Act) 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 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,  as the case may be,  in order to make the  Final
     Supplemented  Prospectus not  misleading in the light of the  circumstances
     when it (or in lieu  thereof,  the notice  referred to in Rule 173(a) under
     the  Securities  Act) is delivered,  or if for any other reason it shall be
     necessary during such period to amend or supplement the Final  Supplemented
     Prospectus or to file under the Exchange Act any document  incorporated  by
     reference in the Final Supplemented  Prospectus in order to comply with the
     Securities  Act or the Exchange Act, the Company  forthwith will (i) notify
     the  Underwriters to suspend  solicitation of purchases of the Senior Notes
     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 (or in lieu thereof, the notice referred to in Rule
     173(a) under the Securities Act) 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 Senior Notes
     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
     Securities 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
     Exchange 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  Representatives  and  Dewey
     Ballantine LLP.


                                       9


(c)      The Company will endeavor, in cooperation with the Underwriters, 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 Representatives 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 Securities Act) covering a twelve-month period beginning not
         later than the first day of the Company's fiscal quarter next following
         the "effective date" (as defined in Rule 158) of the Registration
         Statement.

(e)      As soon as practicable after the date of this Agreement, and in any
         event within the time prescribed by Rule 424 under the Securities Act,
         to file the Final Supplemented Prospectus, in a form approved by the
         Representatives, such approval not to be unreasonably withheld, with
         the Commission and to advise the Representatives of such filing and to
         confirm such advice in writing. Furthermore, the Company will make any
         other required filings pursuant to Rule 433(d)(1) of the Securities Act
         within the time required by such Rule.

(f)      During a period of 15 days from the date of this Agreement, the Company
         will not, without the Representatives' 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
         Representatives agree that commercial paper or other debt securities
         with scheduled maturities of less than one year are not subject to this
         Section 4(f).

     of copies of the  Registration  Statement as  originally  filed and of each

     shall pay all other expenses incurred by them in connection with their
     offering of the Senior Notes including fees and disbursements of their
     counsel, Dewey Ballantine LLP.

SECTION 6. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The obligations of the
Underwriters 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
     or  pursuant  to Section 8A of the  Securities  Act  against the Company or
     related to the offering shall be pending before, or to the knowledge of the
     Company  threatened  by,  the  Commission  on such  date.  If filing of the
     Pricing Prospectus or the Final Supplemented Prospectus,  or any supplement
     thereto,  is required pursuant to Rule 424, the Pricing  Prospectus and the

     such order or orders heretofore entered, copies of which have
     heretofore been delivered to the Representatives, 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).
                                       11


(c)  On the Closing Date the Representatives shall have received:

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

(2)      The opinion,  dated the Closing Date, of Troutman  Sanders LLP,

(3)      The opinion,  dated the Closing Date,  of Emmett,  Marvin & Martin,

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

(e)  The  Representatives  shall  have  received  on the date  hereof  and shall
     receive on the Closing Date from Deloitte & Touche LLP, a letter or letters
     addressed  to the  Representatives  (which may refer to letters  previously
     delivered to the  Representatives)  dated the respective  dates of delivery
     thereof to the effect that: (A) they are an independent  registered  public
     accounting  firm with  respect to the  Company  within  the  meaning of the
     Securities Act and the rules and regulations  under the Securities Act; (B)
     in their opinion, the financial statements audited by them and incorporated
     by reference in the  Registration  Statement and the Pricing  Prospectus or
     the  Registration   Statement,   the  Pricing   Prospectus  and  the  Final
     Supplemented Prospectus,  as applicable,  comply as to form in all material
     respects with the applicable  accounting  requirements  of the Exchange Act
     and the rules and regulations  under the Exchange Act; and (C) on the basis

                                       12


     of certain limited  procedures  performed through a specified date not more
     than  three  business  days  prior to the date of such  letter,  namely (i)
     reading the minute books of the Company;  (ii)  performing  the  procedures
     specified by the standards of the Public Company Accounting Oversight Board
     (United  States)  ("PCAOB")  for a review of  interim  financial  statement
     information  as  described  in  PCAOB  Interim  Standard  AU 722,  "Interim
     Financial Information",  on the unaudited financial statements,  if any, of
     the Company incorporated by reference in the Registration Statement and the
     Pricing  Prospectus or the Registration  Statement,  the Pricing Prospectus
     and the Final  Supplemented  Prospectus,  as applicable,  and on the latest
     available  unaudited  financial  statements of the Company, if any, for any
     calendar quarter  subsequent to the date of those incorporated by reference
     in  the   Registration   Statement  and  the  Pricing   Prospectus  or  the
     Registration  Statement,  the Pricing Prospectus and the Final Supplemented
     Prospectus, as applicable;  and (iii) making inquiries of certain officials
     of the Company who have responsibility for financial and accounting matters
     regarding such unaudited  financial  statements or any specified  unaudited
     amounts  derived   therefrom  (it  being   understood  that  the  foregoing
     procedures  do  not  constitute  an  audit  performed  in  accordance  with
     generally accepted auditing standards and they would not necessarily reveal
     matters of  significance  with respect to the comments made in such letter,
     and accordingly  that Deloitte & Touche LLP make no  representations  as to
     the sufficiency of such procedures for the 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 Registration Statement
     and the  Pricing  Prospectus  or the  Registration  Statement,  the Pricing
     Prospectus and the Final Supplemented Prospectus, as applicable for them to
     be  in  conformity  with  GAAP;  (2)  such  unaudited  condensed  financial
     statements  do not  comply  as to form in all  material  respects  with the
     applicable  accounting  requirements  of the  Exchange 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 and the  unaudited  Ratio of Earnings  to Fixed  Charges set
     forth in the  Registration  Statement  and the  Pricing  Prospectus  or the
     Registration  Statement,  the Pricing Prospectus and the Final Supplemented
     Prospectus,  as  applicable,  do not agree with the amounts set forth in or
     derived  from  the  unaudited  financial  statements  for the  same  period
     included or incorporated by reference in the Registration Statement; (4) as
     of a specified  date not more than three business days prior to the date of
     delivery of such letter,  there has been any change in the capital stock or
     long-term  debt of the  Company or any  decrease  in net assets as compared
     with amounts shown in the latest unaudited  balance sheet,  incorporated by
     reference in the Registration  Statement and the Pricing  Prospectus or the
     Registration  Statement,  the Pricing Prospectus and the Final Supplemented
     Prospectus,  as  applicable,  except in each case for changes or  decreases
     which (i) the  Registration  Statement  and the Pricing  Prospectus  or the
     Registration  Statement,  the Pricing Prospectus and the Final Supplemented
     Prospectus,  as applicable,  disclose, have occurred or may occur, (ii) are
     occasioned  by the  declaration  of  dividends,  (iii)  are  occasioned  by


                                       13



     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 the  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 and the  unaudited  Ratio of Earnings  to Fixed  Charges for any
     calendar  quarter  subsequent  to those set forth in (3) above,  which,  if
     available, shall be set forth in such letter, do not agree with the amounts
     set forth in or derived from the  unaudited  financial  statements  for the
     same period or were not determined on a basis substantially consistent with
     that  of  the   corresponding   audited   amounts  or  ratios  included  or
     incorporated  by reference in the  Registration  Statement  and the Pricing
     Prospectus or the Registration  Statement,  the Pricing  Prospectus and the
     Final Supplemented Prospectus, as applicable.

(f) On the Closing Date, Dewey Ballantine LLP, counsel for the Underwriters
    shall have been furnished with such documents and opinions as they may
    reasonably require for the purpose of enabling them 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
    Representatives and Dewey Ballantine LLP, counsel for the Underwriters.

(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 Exchange 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 Representatives,
    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 Representatives by notice to the Company at any time prior to the Closing
Date, and such termination shall be without liability of any party to any other
party except as provided in Sections 5, 8 and 10(b) hereof.


                                       14



SECTION 7.        CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.
                  --------------------------------------------

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

SECTION 8.        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 Securities Act or Section 20(a) of the Exchange 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 Securities Act, the Exchange
Act or otherwise, and to reimburse 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 Basic Prospectus, the Pricing
Prospectus, any Permitted Free Writing 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 Exchange Act which are incorporated therein by reference, in any
Preliminary Prospectus, the Registration Statement, the Basic Prospectus, the
Pricing Prospectus, any Permitted Free Writing Prospectus, the Final
Supplemented Prospectus as so amended or supplemented, or in any free writing
prospectus used by the Company other than a Permitted Free Writing Prospectus,
or arise out of or are based upon any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or actions arise out of or are based upon any such untrue
statement or alleged untrue statement or omission or alleged omission which was
made in such Preliminary Prospectus, Registration Statement, Basic Prospectus,
Pricing Prospectus, Permitted Free Writing Prospectus or Final Supplemented
Prospectus in reliance upon and in conformity with information furnished in
writing to the Company by any Underwriter, through the Representatives for use
therein. 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 8, 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 8. 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


                                       15


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 Securities Act or Section 20(a) of the Exchange
Act to the same extent and upon the same terms as the indemnity agreement of the
Company set forth in Section 8(a) hereof, but only with respect to alleged
untrue statements or omissions made in the Registration Statement, the
Preliminary Prospectus, the Basic Prospectus, the Pricing Prospectus, any
Permitted Free Writing Prospectus or the Final Supplemented Prospectus, or such
documents as amended or supplemented, in reliance upon and in conformity with
information furnished in writing to the Company by any Underwriter through the
Representatives for use therein.

SECTION 9.   REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.
             --------------------------------------------------------------

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

SECTION 10.       TERMINATION OF AGREEMENT.
                  ------------------------

(a)  The Representatives 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  in  securities
     generally,  (ii)  minimum  or maximum  ranges  for  prices  shall have been

                                       16

     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 Representatives,  the offering, sale or delivery
     of the  Senior  Notes on the terms and in the manner  contemplated  by this
     Agreement and the Final Supplemented  Prospectus shall have been materially
     impaired.

(b)  If this Agreement  shall be terminated by the  Representatives  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 Senior Notes and,
     upon such  reimbursement,  the Company  shall be absolved  from any further
     liability hereunder, except as provided in Sections 5 and 8.

                     SECTION 11. DEFAULT BY AN UNDERWRITER

                  If an Underwriter shall fail on the Closing Date to purchase
the Senior Notes that it is obligated to purchase under this Agreement (the
"Defaulted Securities"), the Representatives 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 Representatives 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
     Senior Notes, the non-defaulting Underwriters shall be obligated, severally
     and not  jointly,  to purchase the full amount  thereof in the  proportions
     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 Senior
     Notes,  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 Representatives or the Company shall

                                       17


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, the
Pricing Prospectus or Final Supplemented Prospectus or in any other documents or
arrangements.

SECTION 12.       NOTICES.  All notices and other  communications  hereunder
shall be in writing and shall be deemed to have been duly given if mailed or

                             SOUTHERN POWER COMPANY
                          Series E _____% Senior Notes
                              due November 15, 2036

Ladies and Gentlemen:

                  We have acted as counsel to Southern Power Company (the
"Company") in connection with (i) the Company's issuance of $200,000,000
aggregate principal amount of its Series E ____% Senior Notes due November 15,
2036 (the "Notes") pursuant to a Senior Note Indenture dated as of June 1, 2002,
by and between the Company and The Bank of New York, as trustee (the "Trustee"),
as heretofore supplemented and as further supplemented by the Third Supplemental
Indenture dated as of _______, 2006 (collectively, the "Indenture"); and (ii)
the purchase by the Underwriters (as defined herein) of the Notes pursuant to
the terms of an Underwriting Agreement dated ________, 2006 (the "Underwriting
Agreement"), among the Company and the Underwriters named in Schedule I thereto
(the "Underwriters") for whom you are acting as representatives (the
"Representatives"). This opinion is being delivered to you as Representatives
pursuant to Section 6(c)(1) thereof.

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

                  In rendering the opinions expressed below, we have examined
the registration statement on Form S-3, as amended (File No. 333-134219)
pertaining to the Notes and certain other securities filed by the Company under
the Securities Act of 1933, as amended (the "Act"), as it became effective under
the Act (the "Registration Statement"); the Company's prospectus dated November
9, 2006 (the "Basic Prospectus") as supplemented by a preliminary prospectus
supplement dated November 13, 2006 (the "Pricing Prospectus"), filed by the




Company pursuant to Rule 424(b) of the rules and regulations of the Securities
and Exchange Commission (the "Commission") under the Act, which, pursuant to
Form S-3, incorporates by reference the Annual Report on Form 10-K of the
Company for the fiscal year ended December 31, 2005, the Quarterly Reports on
Form 10-Q of the Company for the quarterly periods ended March 31, 2006, June
30, 2006 and September 30, 2006 and the Current Reports on Form 8-K of the
Company dated May 6, 2006, May 31, 2006, July 7, 2006 and August 31, 2006 (the
"Pricing Exchange Act Documents"), and a prospectus supplement dated
___________, 2006 (together with the Basic Prospectus, the "Final Supplemented
Prospectus"), filed by the Company pursuant to Rule 424(b) of the rules and
regulations of the Commission under the Act, which, pursuant to Form S-3,
incorporates by reference the Pricing Exchange Act Documents and the Current
Report on Form 8-K of the Company dated ________, 2006 (the "Exchange Act
Documents"), each as filed under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"); and the Indenture. We have also examined the free writing
prospectus prepared by the Company and filed with the Commission on _________,
2006 pursuant to Rule 433 of the Act (the "Permitted Free Writing Prospectus").
The documents listed in Schedule III to the Underwriting Agreement, taken
together, are collectively referred to as the "Pricing Disclosure Package."

                  In addition, we have examined, and have relied as to matters
of fact upon, the documents delivered to you at the closing (except the
certificate representing the Notes, of which we have examined a specimen), and
we have made such other and further investigations as we deemed necessary to
express the opinions hereinafter set forth. In such examination, we have assumed
the genuineness of all signatures (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."

                  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 and relying as to Florida law upon the attached opinion of Beggs
& Lane to the Company, 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 Delaware
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.
                                       2



                  3. All orders, consents or other authorizations or approvals
of the Federal Energy Regulatory Commission and the Commission legally required
for the issuance and sale of the Notes have been obtained; such orders are
sufficient for the issuance and 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 the states of
Delaware, Georgia, Florida or Alabama or any United States governmental body
(other than in connection or in compliance with the provisions of the securities
or "blue sky" laws of any jurisdiction, as to which we express no opinion) is
legally required for the issuance and sale of the Notes in accordance with the
terms of the Underwriting Agreement.

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

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

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

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

                                       3



participation in the conferences referred to above, (i) we are of the opinion
that the Registration Statement, on the Effective Date, and the Final
Supplemented Prospectus, as of __________, 2006, 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 Pricing Disclosure Package, the Final Supplemented
Prospectus or the Exchange Act Documents, and (ii) nothing came to our attention
which gives us reason to believe that the Registration Statement, on the
Effective Date (including the Exchange Act Documents on file with the Commission
as of such date), contained any untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary in order
to make the statements therein not misleading, that the Pricing Disclosure
Package, as of the Applicable Time, included an untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or that the Final Supplemented Prospectus (including the
Exchange Act Documents) contained, as of its date, or contains, on the date
hereof, any untrue statement therein of a material fact or omitted, as of its
date, or omits, on the date hereof, to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, except that in each case we express no opinion
or belief with respect to the financial statements or other financial or
statistical data contained or incorporated by reference in the Registration
Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or
the Exchange Act Documents and with respect to information set forth in the
Pricing Prospectus and the Final Supplemented Prospectus under the caption
"Description of the Series E Senior Notes - Book-Entry-Only Issuance - The
Depository Trust Company."

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


                                       4





                  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.



                               Yours very truly,

                              due November 15, 2036

Ladies and Gentlemen:

                  We have acted as counsel to Southern Power Company (the
"Company") in connection with (i) the Company's issuance of $200,000,000
aggregate principal amount of its Series E ____% Senior Notes due November 15,
2036 (the "Notes") pursuant to a Senior Note Indenture dated as of June 1, 2002,
by and between the Company and the Bank of New York, as trustee (the "Trustee"),
as heretofore supplemented and as further supplemented by the Third Supplemental
Indenture dated as of _______, 2006 (collectively, the "Indenture"); and (ii)
the purchase by the Underwriters (as defined herein) of the Notes pursuant to
the terms of an Underwriting Agreement dated ________, 2006, (the "Underwriting
Agreement"), among the Company and the Underwriters named in Schedule I thereto
(the "Underwriters") for whom you are acting as representatives (the
"Representatives"). This opinion is being delivered to you as Representatives
pursuant to Section 6(c)(2) 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, as amended (File No. 333-134219)
pertaining to the Notes and certain other securities filed by the Company under
the Securities Act of 1933, as amended (the "Act"), as it became effective under
the Act (the "Registration Statement"); the Company's prospectus dated November
9, 2006 (the "Basic Prospectus"), as supplemented by a preliminary prospectus
supplement dated November 13, 2006 (the "Pricing Prospectus"), filed by the



Company pursuant to Rule 424(b) of the rules and regulations of the Securities
and Exchange Commission (the "Commission") under the Act, which, pursuant to
Form S-3, incorporates by reference the Annual Report on Form 10-K of the
Company for the fiscal year ended December 31, 2005, the Quarterly Reports on

"Final Supplemented Prospectus"), filed by the Company pursuant to Rule 424(b)
of the rules and regulations of the Commission under the Act, which, pursuant to

Current Report on Form 8-K of the Company dated __________, 2006 (the "Exchange

writing prospectus prepared by the Company and filed with the Commission on
_________, 2006 pursuant to Rule 433 of the Act (the "Permitted Free Writing
Prospectus"). The documents listed in Schedule III to the Underwriting
Agreement, taken together, are collectively referred to as the "Pricing
Disclosure Package."

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

                  The Indenture and the Underwriting Agreement are herein
referred to 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
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 Delaware
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 Federal Energy Regulatory Commission and the Commission legally required

                                       2


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

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

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

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

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

                                       3



Statement, on the Effective Date, and the Final Supplemented Prospectus, as of
_________, 2006, 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 Pricing Disclosure Package, the Final Supplemented
Prospectus or the Exchange Act Documents, and (ii) nothing came to our attention
which gives us reason to believe (A) that the Registration Statement, on the
Effective Date (including the Exchange Act Documents on file with the Commission
as of such date), contained any untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary in order
to make the statements therein not misleading, (B) that the Pricing Disclosure
Package, as of the Applicable Time, included an untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or (C) that the Final Supplemented Prospectus (including the
Exchange Act Documents) contained, as of its date, or contains, on the date
hereof, any untrue statement of a material fact or omitted, as of its date, or
omits, on the date hereof, to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, except that in each case we express no opinion or belief
with respect to the financial statements or other financial or statistical data
contained or incorporated by reference in the Registration Statement, the
Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange
Act Documents and with respect to information set forth in the Pricing
Prospectus and the Final Supplemented Prospectus under the caption "Description
of the Series E Senior Notes - Book-Entry-Only Issuance - The Depository Trust

concerning any law other than the law of the State of Georgia, the federal law

       As representatives of the several underwriters (the "Underwriters") named
       on Schedule I to the Underwriting Agreement dated ____, 2006 among the
       Underwriters and Southern Power Company (the "Company")


Southern Power Company

                Series E ___% Senior Notes due November 15, 2036

Ladies and Gentlemen:

     We have  acted as  counsel  for The Bank of New  York,  a New York  banking
corporation ("BNY") in connection with the several purchases by the Underwriters
of  $200,000,000  aggregate  principal  amount of Series E ___% Senior Notes due
November  15,  2036 (the  "Notes")  issued by the  Company.  The Notes are being
issued  under the Senior  Note  Indenture  dated as of June 1, 2002  between the
Company and BNY, as trustee (in such  capacity,  the  "Trustee"),  as heretofore
supplemented  and as further  supplemented by the Third  Supplemental  Indenture
dated as of _____, 2006 between the Company and the Trustee  (collectively,  the
"Indenture").

      For purposes of this opinion, we have reviewed the Indenture
and such other documents, records and papers, and satisfied ourselves as to such
other matters, as we have deemed necessary or appropriate for this opinion. As
to questions of fact material to this opinion, we have relied on certificates of
BNY and of public officials. In such review, we have assumed the genuineness of
all signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to the originals of all
documents submitted to us as copies or forms and the authenticity of the





originals of such latter documents. We have assumed that BNY has been duly
incorporated and that the Indenture has been duly authorized, executed and
delivered by the Company and constitutes the valid and binding agreement of, and
is enforceable in accordance with its terms against, the Company.

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

          1)       BNY is a banking corporation validly existing under the laws
of the State of New York with corporate power and authority to enter into and
perform its obligations under the Indenture.

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

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

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

                          Very truly yours,

                             SOUTHERN POWER COMPANY
                          Series E _____% Senior Notes
                              due November 15, 2036

Ladies and Gentlemen:

                  We have represented the Underwriters (hereinafter defined) in
connection with (i) the issuance and sale by Southern Power Company (the
"Company") of $200,000,000 aggregate principal amount of its Series E ____%
Senior Notes due November 15, 2036 (the "Notes") pursuant to a Senior Note

New York, as trustee (the "Trustee"), as heretofore supplemented and as further
supplemented by the Third Supplemental Indenture, dated as of _____________,
2006 (collectively, the "Indenture"); and (ii) the purchase by the Underwriters
(as defined herein) of the Notes pursuant to the terms of an Underwriting
Agreement dated _________, 2006 (the "Underwriting Agreement"), among the
Company and the Underwriters named in Schedule I thereto (the "Underwriters")
for whom you are acting as representatives (the "Representatives"). This opinion
is being delivered to you as Representatives pursuant to Section 6(c)(4)
thereof.

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

                  In rendering the opinions expressed below, we have examined
the registration statement on Form S-3, as amended (File No. 333-134219)
pertaining to the Notes and certain other securities filed by the Company under
the Securities Act of 1933, as amended (the "Act"), as it became effective under



the Act (the "Registration Statement"); the Company's prospectus dated November
9, 2006 (the "Basic Prospectus") as supplemented by a preliminary prospectus
supplement dated November 13, 2006 (the "Pricing Prospectus"), filed by the
Company pursuant to Rule 424(b) of the rules and regulations of the Securities
and Exchange Commission (the "Commission") under the Act, which, pursuant to
Form S-3, incorporates by reference the Annual Report on Form 10-K of the
Company for the fiscal year ended December 31, 2005, the Quarterly Reports on
Form 10-Q of the Company for the quarterly periods ended March 31, 2006, June
30, 2006 and September 30, 2006 and the Current Reports on Form 8-K of the
Company dated May 6, 2006, May 31, 2006, July 7, 2006 and August 31, 2006 (the
"Pricing Exchange Act Documents"), and a prospectus supplement dated _______,
2006 (together with the Basic Prospectus, the "Final Supplemented Prospectus"),
filed by the Company pursuant to Rule 424(b) of the rules and regulations of the
Commission under the Act, which, pursuant to Form S-3, incorporates by reference
the Pricing Exchange Act Documents and the Current Report on Form 8-K of the
Company dated __________, 2006 (the "Exchange Act Documents"), each as filed
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"); and
the Indenture. We have also examined the free writing prospectus prepared by the
Company and filed with the Commission on ________, 2006 pursuant to Rule 433 of
the Act (the "Permitted Free Writing Prospectus"). The documents listed in
Schedule III to the Underwriting Agreement, taken together, are collectively
referred to as the "Pricing Disclosure Package."

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

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

                  Based upon the foregoing,  and subject to the  qualifications
and limitations  stated herein, we are of the opinion, 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 Delaware
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 Federal Energy Regulatory Commission and the Commission legally required
for the issuance and sale of the Notes have been obtained; such orders are
sufficient for the issuance and sale of the Notes; the issuance and sale of the
Notes conform in all material respects with the terms of such orders; and no
other order, consent or other authorization or approval of the State of New York
or United States governmental body (other than in connection or in compliance
with the provisions of the securities or "blue sky" laws of any jurisdiction, as
to which we express no opinion) is legally required for the issuance and sale of
the Notes in accordance with the terms of the Underwriting Agreement.

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

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

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

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



investigations made in connection with the preparation of the Registration
Statement, the Pricing Disclosure Package and the Final Supplemented Prospectus
and our participation in the conferences referred to above, (i) we are of the
opinion that the Registration Statement, on the Effective Date, and the Final
Supplemented Prospectus, as of _____________, 2006, 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 Pricing Disclosure Package, the Final Supplemented
Prospectus or the Exchange Act Documents, and (ii) nothing came to our attention
which gives us reason to believe that the Registration Statement, on the
Effective Date (including the Exchange Act Documents on file with the Commission
as of such date), contained any untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary in order
to make the statements therein not misleading, that the Pricing Disclosure
Package, as of the Applicable Time, included an untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or that the Final Supplemented Prospectus (including the
Exchange Act Documents) contained, as of its date, or contains, on the date
hereof, any untrue statement of a material fact or omitted, as of its date, or
omits, on the date hereof, to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, except that in each case we express no opinion or belief
with respect to the financial statements or other financial or statistical data
contained or incorporated by reference in the Registration Statement, the
Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange
Act Documents and with respect to information set forth in the Pricing
Prospectus and the Final Supplemented Prospectus under the caption "Description
