                                  RECITALS 
  
           WHEREAS, Southern Energy Bowline, L.L.C.,  a Delaware limited
 liability company and a direct or indirect wholly-owned subsidiary of the
 Guarantor (the "Buyer"), has entered into the Bowline Point Generating
 Station Sales Agreement (the "Asset Sales Agreement"), dated as of the date
 hereof with O&R and Con Edison, pursuant to which the Buyer has agreed to
 purchase and O&R and Con Edison have agreed to sell certain electric
 generating assets, as more particularly set forth therein; and 
  
           WHEREAS, the Buyer has entered into the Bowline Adjacent Property
 Sales Agreement (the "Property Sales Agreement"), dated as of the date
 hereof with O&R, pursuant to which the Buyer has agreed to purchase and O&R
 has agreed to sell certain property, as more particularly set forth
 therein; and 
  
           WHEREAS, Guarantor has agreed to guarantee the payment and
 performance obligations of the Buyer under the Asset Sales Agreement and
 the Property Sales Agreement. 
  
           NOW, THEREFORE, the Guarantor agrees as follows: 
  
           Section 1.  Definitions.  (a)  Capitalized terms used herein
 shall have the meanings assigned to them herein or, if not defined herein,
 then such terms shall have the meanings assigned to them in the Asset Sales
 Agreement.
  
           Section 2.  Guaranty.  (a) Guarantor hereby absolutely and
 irrevocably guarantees to O&R and Con Edison and their successors and
 permitted assigns, as primary obligor and not merely as a surety, that the
 Buyer shall:  (i) be bound by and perform, (A) the provisions of Sections
 3.1 (Purchase Price), 3.2 (Purchase Price Adjustment), Section 3.4
 (Proration) and Section 4.2 (Payment of Purchase Price) of the Asset Sales
 Agreement; (ii) pay (A) the amounts required to be paid by the Buyer
 pursuant to Article IX (Indemnification) of the Asset Sales Agreement and
 the Indemnification provisions of each of the Ancillary Agreements, where
 applicable and (B) all other amounts required to be paid by the Buyer under
 the Ancillary Agreements and any other agreement or instrument relating
 thereto not described in (ii)(A) above; and (iii) promptly perform, observe
 and comply with all other obligations, covenants, and undertakings and
 representations and warranties of the Buyer contained in the Asset Sales
 Agreement, the Ancillary Agreement and any other agreement or instrument
 relating thereto (all of such obligations collectively, the "Guaranteed
 Obligations").  Guarantor agrees that such Guaranteed Obligations shall
 forthwith become due and payable by Guarantor or be required to be
 performed by the Guarantor for the purposes of this Guaranty upon the
 occurrence of any event or condition giving rise to the obligation of the
 Buyer so to pay or be performed under the Asset Sales Agreement, Ancillary
 Agreements or any other agreement or instrument relating thereto.

                (b)  Guarantor hereby absolutely and irrevocably guarantees
 to O&R and its successors and permitted assigns, as primary obligor and not
 merely as a surety, that the Buyer shall:  (i) be bound by and perform, (A)
 the provisions of Sections 3.1 (Purchase Price), Section 3.2 (Proration)
 and Section 4.2 (Payment of Purchase Price) of the Property Sales
 Agreement; (ii) pay (A) the amounts required to be paid by the Buyer
 pursuant to Article IX (Indemnification) of the Property Sales Agreement
 and (iii) promptly perform, observe and comply with all other obligations,
 covenants, and undertakings and representations and warranties of the Buyer
 contained in the Property Sales Agreement or any other agreement or
 instrument relating thereto (the "Guaranteed Property Obligations"). 
 Guarantor agrees that such Guaranteed Property Obligations shall forthwith
 become due and payable by Guarantor or be required to be performed by the
 Guarantor for the purposes of this Guaranty upon the occurrence of any
 event or condition giving rise to the obligation of the Buyer so to pay or
 be performed under the Property Sales Agreement or any other agreement or
 instrument relating thereto.
  
                (c)  In the event that the Buyer shall fail to perform such
 Guaranteed Obligations or Guaranteed Property Obligations at the times and
 in the manner provided in the Asset Sales Agreement, the Property Sales
 Agreement, the Ancillary Agreements and any other agreement or instrument
 relating thereto, the Guarantor, within thirty (30) days of receipt of
 written notice from O&R and/or Con Edison, as applicable, of the Buyer's
 failure to perform, shall duly perform or cause to be performed the same.
  
                (d)  Subject to the foregoing provisions, this Guaranty
 shall be an absolute, unconditional, present and continuing guaranty of
 payment and performance (not merely of collection or collectability) which
 shall remain in full force and effect until the first to occur of (i) the
 date that each and all of the Guaranteed Obligations and Guaranteed
 Property Obligations shall have been fully and satisfactorily discharged in
 accordance with the terms and provisions of the Asset Sales Agreement, the
 Property Sales Agreement, the Ancillary Agreements and any other agreement
 or instrument relating thereto or (ii) such date (the "Attainment Date") on
 or after the second anniversary of the Closing Date (as defined in the
 Asset Sales Agreement) that the Buyer shall have attained for at least four
 (4) consecutive fiscal quarters (A) "net worth", as determined in
 accordance with U.S. generally accepted accounting principles and reflected
 in a balance sheet certified by an independent certified public accounting
 firm of national reputation, at least equal to an amount equal to one-third
 of the sum of the Purchase Price (as described in Section 3.1 of the Asset
 Sales Agreement) and the Purchase Price (as described in Section 3.1 of the
 Property Sales Agreement).
  
           Section 3.  Guaranty Absolute.  The liability of Guarantor under
 this Guaranty shall be unaffected by:
  
                (a)  any lack of validity of the Asset Sales Agreement or
 the Property Sales Agreement which is caused by an act or failure to act of
 Buyer or the Guarantor;
  
                (b)  the occurrence or continuance of any event of
 bankruptcy, reorganization or insolvency with respect to Buyer or any other
 Person (for purposes hereof, "Person" shall include any natural person,
 corporation, partnership, firm, association, governmental authority or any
 other entity whether acting in an individual, fiduciary or other capacity),
 or the dissolution, liquidation or winding up of Buyer or any other Person;
  
                (c)  any amendment, supplement, reformation or other
 modification of the Asset Sales Agreement or the Property Sales Agreement;

                (d)  the exercise, non-exercise or delay in exercising, by
 O&R or Con Edison, as applicable, or any other Person of any of their
 rights and remedies under this Guaranty, the Asset Sales Agreement or the
 Property Sales Agreement;
  
                (e)  any permitted assignment or other transfer of this
 Guaranty by O&R or Con Edison, as applicable, or any permitted assignment
 or other transfer of the Asset Sales Agreement or the Property Sales
 Agreement in whole or in part;
  
                (f)  any change in control of the Buyer;
  
                (g)  any sale, transfer or other disposition by Guarantor of
 any direct or indirect interest it may have in Buyer; or
  
                (h)  the absence of any notice to, or knowledge by,
 Guarantor of the existence or occurrence of any of the matters or events
 set forth in the foregoing clauses.
  
           Section 4.  Waiver.  In addition to waiving any defenses to which
 clauses (a) through (h) of Section 3 may refer:
  
                (a)  Guarantor waives, and agrees that it shall not at any
 time insist upon, plead or in any manner whatever claim or take the benefit
 or advantage of, any appraisal, valuation, stay, extension, marshalling of
 assets or redemption laws, or exemption, whether now or at any time
 hereafter in force, which may delay, prevent or otherwise affect the
 performance by Guarantor of its obligations under, or the enforcement by
 O&R or Con Edison, as applicable, of, this Guaranty.
  
                (b)  Guarantor waives all notices, diligence, presentment
 and demand (whether for nonpayment or protest or of acceptance, maturity,
 extension of time, change in nature or form of the Guaranteed Obligations
 or the Guaranteed Property Obligations, acceptance of security, release of
 security, composition or agreement arrive at as to the amount of, or the
 terms of, the Guaranteed Obligations or the Guaranteed Property
 Obligations, notice of adverse change in Buyer's financial condition, or
 any other fact which might materially increase the risk to Guarantor
 hereunder) with respect to the Guaranteed Obligations or the Guaranteed
 Property Obligations which are not specifically provided for in the Asset
 Sales Agreement or the Property Sales Agreement, and any other demands
 whatsoever which are not specifically provided for in the Asset Sales
 Agreement or the Property Sales Agreement, and waives the benefit of all
 provisions of law which are in conflict with the terms of this Guaranty.
  
                (c)  Until payment and satisfaction in full of all
 Guaranteed Obligations and the Guaranteed Property Obligations, Guarantor
 irrevocably waives any right it may have to bring a case or proceeding
 against Buyer by reason of their performance under this Guaranty or with
 respect to any other obligation of Buyer to Guarantor, under any state or
 federal bankruptcy, insolvency, reorganization, moratorium or similar laws
 for the relief of debtors.
  
           Section 5.  Representations and Warranties.  Guarantor represents
 and warrants as follows:
  
                (a)  Due Organization.  Guarantor is a corporation duly
 organized and validly existing under the laws of Delaware.
  
                (b)  Power and Authority.  Guarantor has full corporate
 power, authority and legal right to enter into this Guaranty and to perform
 its obligations hereunder.

                (c)  Due Authorization.  This Guaranty has been duly
 authorized, executed and delivered by Guarantor.
  
                (d)  Enforceability.  This Guaranty constitutes the legal,
 valid and binding obligation of Guarantor enforceable against Guarantor in
 accordance with its terms, except as enforceability may be limited by
 applicable bankruptcy, insolvency, moratorium or other similar laws
 affecting creditors' rights generally.
  
                (e)  No Conflicts.  The execution and delivery by Guarantor
 of this Guaranty and the performance by Guarantor of its obligations
 hereunder will not (i) violate the provisions of Guarantor's certificate of
 incorporation or bylaws; (ii) violate the provisions of any law applicable
 to Guarantor or the transactions contemplated hereby; or (iii) result in a
 breach of or constitute a default under any agreement to which Guarantor is
 a party or by which it or its assets or property are bound which breach or
 default would have a material adverse effect on Guarantor's ability to
 perform its obligations hereunder.
  
                (f)  No Proceedings.  There is no action, suit or proceeding
 at law or in equity or by or before any governmental authority or arbitral
 tribunal now pending or, to the best knowledge of Guarantor, threatened
 against Guarantor which reasonably could be expected to have a material
 adverse effect on Guarantor's ability to perform its obligations under this
 Guaranty.
  
                (g)  No Claims.  Guarantor's obligations under this Guaranty
 are not subject to any offsets or claims of any kind against Buyer, O&R or
 Con Edison, as applicable, or any other Person.
  
           Section 6. Repayment and Reinstatement.  If any claim is ever
 made upon O&R or Con Edison, as applicable, or any Person claiming through
 O&R or Con Edison, as applicable, for repayment or disgorgement of any
 amount or amounts received by O&R or Con Edison, as applicable, from the
 Buyer in payment of the Guaranteed Obligations or the Guaranteed Property
 Obligations and O&R or Con Edison, as applicable, or such Person, as the
 case may be, repays or disgorges all or any part of said amount, then,
 notwithstanding any revocation or termination of this Guaranty, Guarantor
 shall be and remain liable to O&R or Con Edison, as applicable, or such
 Person, as the case may be, under the terms of this Guaranty for the amount
 so repaid, to the same extent as if such amount had never originally been
 received by O&R or Con Edison, as applicable, or such Person, as the case
 may be.
  
           Section 7.  Amendments; Waivers; Etc.  Neither this instrument
 nor any term hereof may be changed, waived, discharged or terminated
 orally, but only by an instrument in writing signed by O&R or Con Edison,
 as applicable, and Guarantor, as the case may be.  No delay or failure by
 O&R or Con Edison, as applicable, to exercise any remedy against Buyer or
 Guarantor will be construed as a waiver of that right or remedy.  No
 failure on the part of O&R or Con Edison, as applicable, to exercise, and
 no delay in exercising, any right hereunder shall operate as a waiver
 thereof, nor shall any single or partial exercise of any right hereunder
 preclude any other or further exercise thereof or the exercise of any other
 right.  The remedies herein provided are cumulative and not exclusive of
 any remedies provided by any applicable law.
  
           Section 8.  Severability.  In the event that the provisions of
 this Guaranty are claimed or held to be inconsistent with any other
 instrument evidencing or securing O&R or the Guaranteed Obligations, the
 terms of this Guaranty shall remain fully valid and effective.  If any one
 or more of the provisions of this Guaranty should be determined to be
 illegal or unenforceable, all other provisions shall remain effective.

           Section 9.  Assignment.
  
                (a)  Assignability.  Guarantor shall not have the right to
 assign any of Guarantor's rights or obligations under this Guaranty.  O&R
 or Con Edison, as applicable, may, at any time and from time to time,
 assign, in whole or in part, their respective rights hereunder to any
 Person to whom O&R or Con Edison, as applicable, has the right to assign
 their rights or obligations under and, pursuant to the terms of the Asset
 Sales Agreement or the Property Sales Agreement, whereupon such assignee
 shall succeed to all rights of O&R or Con Edison, as applicable, hereunder,
 as the case may be.
  
                (b)  Successors and Assigns.  Subject to Section 9(a)
 hereof, all of the terms of this instrument shall be binding upon and inure
 to the benefit of the parties hereto and their respective successors and
 assigns.
  
           Section 10.  Addresses for Notices.  All notices and other
 communications provided for hereunder shall be given in accordance with the
 notice requirements of the Asset Sales Agreement and if to Guarantor, at
 the address specified below the space for its execution of this Guaranty.
  
           Section 11.  Jurisdiction.
  
                (a)  To the extent permitted by applicable law, Guarantor
 hereby irrevocably submits to the jurisdiction of any state or federal
 court sitting in New York City in any action or proceeding arising out of
 or relating to this Guaranty, and Guarantor hereby irrevocably agrees that
 all claims in respect of such action or proceeding may be heard and
 determined in such a court.  Guarantor, O&R and Con Edison hereby
 irrevocably waive, to the fullest extent they may effectively do so, the
 defense of an inconvenient forum to the maintenance of such action or
 proceeding.  To the extent permitted by applicable law, Guarantor
 irrevocably consents to the service of any and all process in any such
 action or proceedings by the mailing of copies of such process to Guarantor
 at its address specified below the space for its execution of this
 Guaranty.  Guarantor agrees that a final judgment in any such action or
 proceeding shall be conclusive and may be enforced in other jurisdictions
 by suit on the judgment or in any other manner provided by law.
  
                (b)  To the extent that Guarantor has or hereafter may
 acquire any immunity from jurisdiction of any court or from any legal
 process otherwise consented to in paragraph (a) of this section (whether
 through service or notice, attachment prior to judgment, attachment in aid
 of execution, execution or otherwise) with respect to itself or its
 property, to the extent permitted by law, Guarantor hereby irrevocably
 waives such immunity in respect of its obligations under this Guaranty.
  
           Section 12.  Governing Law.  This Guaranty shall be governed by,
 and construed in accordance with, the laws of the state of New York except
 the choice of law rules.
  
           Section 13.  Entire Agreement.  This Guaranty contains the
 complete agreement of Guarantor with respect to the matters contained
 herein and supersedes all other negotiations or agreements, whether written
 or oral, with respect to the subject matter hereof.

  
           IN WITNESS WHEREOF, Guarantor has signed this Guaranty under seal
 effective as of the date first above written.
