16, 2005, between CENTERPOINT ENERGY TRANSITION BOND COMPANY II, LLC, a Delaware

      WHEREAS, the Issuer desires to purchase the Transition Property created

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained and intending to be legally bound hereby, the parties hereto
agree as follows:

                                    ARTICLE I

                                   DEFINITIONS

      Section 1.01 Definitions. Capitalized terms used herein and not otherwise
defined herein have the meanings assigned to them in Appendix A to this
Agreement.

      Section 1.02 Other Definitional Provisions.

            (a) "Agreement" means this Transition Property Sale Agreement, as
      the same may be amended and supplemented from time to time.

            (b) Non-capitalized terms used herein which are defined in the Texas
      Electric Choice Plan, as the context requires, have the meanings assigned
      to such terms in the Texas Electric Choice Plan, but without giving effect
      to amendments to the Texas Electric Choice Plan after the date hereof
      which have a material adverse effect on the Issuer or the Transition
      Bondholders.

            (c) All terms defined in this Agreement shall have such defined
      meanings when used in any certificate or other document made or delivered
      pursuant hereto unless otherwise defined therein.

            (d) The words "hereof," "herein," "hereunder" and words of similar
      import when used in this Agreement shall refer to this Agreement as a
      whole and not to any particular provision of this Agreement; Section,
      Schedule and Exhibit references contained in this Agreement are references
      to Sections, Schedules and Exhibits in or to

                                      -1-
<PAGE>

      this Agreement unless otherwise specified; and the term "including" shall
      mean "including without limitation."

            (e) The definitions contained in this Agreement are applicable to
      the singular as well as the plural forms of such terms.

                                   ARTICLE II

                      CONVEYANCE OF THE TRANSITION PROPERTY

      Section 2.01 Conveyance of the Transition Property.

            (a) In consideration of the Issuer's payment to or upon the order of
      the Seller of $1,837,990,612 (the "Purchase Price"), subject to the
      satisfaction or waiver of the conditions specified in Section 2.02, the
      Seller does hereby irrevocably sell, transfer, assign, set over and
      otherwise convey to the Issuer, without recourse (subject to the
      obligations of the Seller herein) or warranty, except as set forth herein,
      all right, title and interest of the Seller in, to and under the Financing
      Order as identified in the Bill of Sale delivered pursuant to Section
      2.02(i) on or prior to the Transfer Date whereupon such rights and
      interests under the Financing Order shall become the Transition Property
      (such sale, transfer, assignment, setting over and conveyance of the
      Transition Property to include, to the fullest extent permitted by the
      Texas Electric Choice Plan, the right to impose, collect and receive the
      Transition Charges, as the same may be adjusted from time to time). Such
      sale, transfer, assignment, setting over and conveyance of the Transition
      Property is hereby expressly stated to be a sale or other absolute
      transfer and, pursuant to Section 39.308 of the Texas Electric Choice Plan
      and other applicable law, is a true sale and is not a secured transaction
      and title, legal and equitable, has passed to the Issuer. The preceding
      sentence is the statement referred to in Section 39.308 of the Texas
      Electric Choice Plan. The Seller agrees and confirms that upon payment of
      the Purchase Price and the execution and delivery of this Agreement and
      the Bill of Sale, the sale, transfer and assignment hereunder shall be
      effective and the Seller shall have no right, title or interest in, to or
      under the Transition Property.

            (b) Subject to the satisfaction or waiver of conditions specified in
      Section 2.02, the Issuer does hereby purchase the Transition Property from
      the Seller for the consideration set forth in paragraph (a) above.

            (c) The Seller and the Issuer each acknowledge and agree that the
      purchase price for the Transition Property sold pursuant to this Agreement
      is equal to its fair market value at the time of sale.

            (d) Notwithstanding the foregoing, in the event that the sale,
      transfer, assignment, setting over and conveyance of the Transition
      Property is determined by any court of competent jurisdiction not to be a
      true sale as contemplated by the parties and as provided in Section 39.308
      of the Texas Electric Choice Plan, then such sale, transfer, assignment,
      setting over and conveyance shall be treated as a pledge of and grant of a
      security interest in the Transition Property under Section 39.309 of the
      Texas Electric

                                      -2-

      Choice Plan and under Articles 8 and 9 of the Uniform Commercial Code as
      enacted in the State of Texas and each other applicable jurisdiction (the
      "UCC"), and the Seller shall be deemed to have granted, and does hereby
      grant, as of the date hereof, a security interest to the Issuer on behalf
      of itself and the Indenture Trustee in the Transition Property to secure a
      payment obligation incurred by the Seller in the amount paid by the Issuer
      for the Transition Property.

      Section 2.02 Conditions to Conveyance of the Transition Property . The
obligation of the Seller to sell, and the obligation of the Issuer to purchase
the Transition Property on the Transfer Date shall be subject to and conditioned
upon the satisfaction or waiver of each of the following conditions:

            (i) on or prior to the Transfer Date, the Seller shall deliver to
      the Issuer a duly executed Bill of Sale identifying the Transition
      Property, substantially in the form of Exhibit A hereto;

            (ii) as of the Transfer Date, the representations and warranties of
      the Seller in this Agreement shall be true and correct in all material
      respects and no material breach by the Seller of its covenants in this
      Agreement shall exist and the Seller shall have delivered to the Issuer
      and the Indenture Trustee an Officer's Certificate to such effect and no
      Servicer Default shall have occurred and be continuing;

            (iii) as of the Transfer Date:

                  (A) the Issuer shall have sufficient funds available to pay
            the purchase price for the Transition Property to be purchased on
            such date, and

                  (B) all conditions set forth in the Indenture to the issuance
            of the Transition Bonds intended to provide such funds shall have
            been satisfied or waived;

            (iv) on or prior to the Transfer Date, the Seller shall have taken
      all actions required under the Texas Electric Choice Plan, the Financing
      Order and other applicable law for the Issuer to have ownership of the
      Transition Property, free and clear of all Liens other than Liens created
      by the Issuer pursuant to the Indenture; and the Issuer, or the Servicer
      on behalf of the Issuer, shall have taken any action required for the
      Issuer to grant the Indenture Trustee a first priority perfected security
      interest in the Trust Estate and maintain such security interest as of
      such date (including all actions required under the Texas Electric Choice
      Plan, the Financing Order and the UCC);

            (v) the Seller shall have delivered to each Rating Agency and to the
      Issuer any Opinions of Counsel requested by the Rating Agencies;

            (vi) the Seller shall have delivered to the Indenture Trustee and
      the Issuer an Officer's Certificate confirming the satisfaction of each
      relevant condition precedent specified in this Section 2.02; and

                                      -3-
<PAGE>

            (vii) the Seller shall have received the Purchase Price in funds
      immediately available on the Transfer Date.

      As of the Transfer Date, the Seller makes the following representations
and warranties on which the Issuer has relied and will rely in acquiring the
Transition Property. The following representations and warranties are made under
existing law as in effect as of the Transfer Date. The Seller shall not be in
breach of any representation or warranty herein as a result of a change in law
occurring after the Transfer Date, including by means of legislative enactment,
constitutional amendment or voter initiative. The representations and warranties
shall survive the sale of the Transition Property to the Issuer and the pledge
thereof on the Transfer Date to the Indenture Trustee pursuant to the Indenture.

      Section 3.01 Organization and Good Standing. The Seller is a limited
liability company duly organized and in good standing under the laws of the
State of Texas, with limited liability company power and authority to own its
properties and to conduct its business as currently owned or conducted.

      Section 3.02 Due Qualification. The Seller is duly qualified to do
business as a foreign limited liability company in good standing, and has
obtained all necessary licenses and approvals, in all jurisdictions in which the
ownership or lease of property or the conduct of its business requires such
qualifications, licenses or approvals (except where the failure to so qualify or
obtain such licenses and approvals would not be reasonably likely to have a
material adverse effect on the Seller's business, operations, assets, revenues
or properties).

      Section 3.03 Power and Authority. The Seller has the limited liability
company power and authority to obtain the Financing Order and to execute and
deliver this Agreement and to carry out its terms; the Seller has the limited
liability company power and authority to own the rights and interests under the
Financing Order, and to sell and assign the rights and interests under the
Financing Order to the Issuer, whereupon (subject to the effectiveness of the
Issuance Advice Letter) such rights and interests will become the Transition
Property; and the execution, delivery and performance of this Agreement have
been duly authorized by the Seller by all necessary limited liability company
action.

      Section 3.04 Binding Obligation. This Agreement constitutes a legal, valid
and binding obligation of the Seller, enforceable against the Seller in
accordance with its terms, subject to bankruptcy, receivership, insolvency,
reorganization, moratorium and other laws relating to or affecting creditors' or
secured parties' rights generally from time to time in effect and to general
principles of equity (including concepts of materiality, reasonableness, good
faith and fair dealing), regardless of whether considered in a proceeding in
equity or at law.

      Section 3.05 No Violation. The consummation of the transactions
contemplated by this Agreement and the fulfillment of the terms hereof do not:
(i) conflict with or result in any breach of any of the terms and provisions of,
or constitute (with or without notice or lapse of time) a

<PAGE>

default under, the articles of organization or limited liability company
regulations of the Seller, or any indenture, mortgage, credit agreement or other
agreement or instrument to which the Seller is a party or by which it or its
properties is bound; (ii) result in the creation or imposition of any Lien upon
any of the Seller's properties pursuant to the terms of any such indenture,
agreement or other instrument (except for any Lien created in favor of the
Transition Bondholders pursuant to Section 39.309 of the Texas Electric Choice
Plan or any Lien created by the Issuer under the Basic Documents); or (iii)
violate any existing law or any existing order, rule or regulation applicable to
the Seller of any Governmental Authority having jurisdiction over the Seller or
its properties.

      Section 3.06 No Proceedings. Except as disclosed in the Issuer's
prospectus dated December 6, 2005 and the related prospectus supplement dated
December 9, 2005 relating to the Transition Bonds (together, the "Prospectus"),
there are no proceedings pending and, to the Seller's knowledge, (x) there are
no proceedings threatened and (y) there are no investigations pending or
threatened before any Governmental Authority having jurisdiction over the Seller
or its properties involving or relating to the Seller or the Issuer or, to the
Seller's knowledge, any other Person:

      the Financing Order;

            (ii) seeking to prevent the issuance of the Transition Bonds or the
      consummation of any of the transactions contemplated by this Agreement or
      any of the other Basic Documents;

            (iii) seeking any determination or ruling that could reasonably be
      expected to materially and adversely affect the performance by the Seller
      of its obligations under, or the validity or enforceability of, this
      Agreement, any of the other Basic Documents or the Transition Bonds; or

            (iv) challenging the Seller's treatment of the Transition Bonds as
      debt of CenterPoint Energy, Inc. for federal or state income, gross
      receipts or franchise tax purposes.

      Section 3.07 Approvals. Except for filings under the UCC and the Texas
Electric Choice Plan, no approval, authorization, consent, order or other action
of, or filing with, any Governmental Authority is required under an applicable
law, rule or regulation in connection with the execution and delivery by the
Seller of this Agreement, the performance by the Seller of the transactions
contemplated hereby or the fulfillment by the Seller of the terms hereof, except
those that have been obtained or made and those that the Seller, in its capacity
as Servicer under the Servicing Agreement, is required to make in the future
pursuant to the Servicing Agreement.

      to the Transition Property (including the Financing Order and the Issuance
      Advice Letter) is correct in all material respects.

                                      -5-
<PAGE>

            (b) Effect of Transfer. It is the intention of the parties hereto
      that (other than for United States federal income tax purposes and, to the
      extent consistent with applicable state tax laws, state income and
      franchise tax purposes) the sale, transfer, assignment, setting over and
      conveyance herein contemplated constitutes a sale or other absolute
      transfer of all right, title and interest of the Seller in, to and under
      the Financing Order from the Seller to the Issuer whereupon (subject to
      the effectiveness of the Issuance Advice Letter) such rights and interests
      shall become the Transition Property; upon execution and delivery of this
      Agreement and the Bill of Sale and payment of the Purchase Price, the
      Seller will have no right, title or interest in, to or under the
      Transition Property; and that such Transition Property would not be a part
      of the estate of the Seller as debtor in the event of the filing of a
      bankruptcy petition by or against the Seller under any bankruptcy law.

            (c) Transfer Filings.

                  (i) The Seller is the sole owner of the rights and interests
            under the Financing Order to be sold to the Issuer on the Transfer
            Date.

                  (ii) On the Transfer Date, immediately upon the sale
            hereunder, the Transition Property will have been validly sold,
            assigned, transferred, set over and conveyed to the Issuer free and
            clear of all Liens (except for any Lien created in favor of the
            Transition Bondholders pursuant to Section 39.309 of the Texas
            Electric Choice Plan or any Lien created by the Issuer under the
            Basic Documents).

                  (iii) All actions or filings (including filings with the Texas
            Secretary of State in accordance with the rules prescribed under the
            Texas Electric Choice Plan and the UCC) necessary in any
            jurisdiction to give the Issuer a perfected ownership interest
            (subject to any Lien created in favor of the Transition Bondholders
            pursuant to Section 39.309 of the Texas Electric Choice Plan or any
            Lien created by the Issuer under the Basic Documents) in the
            Transition Property and to grant to the Indenture Trustee a first
            priority perfected security interest in the Transition Property,
            free and clear of all Liens of the Seller or anyone else (except for
            any Lien created in favor of the Transition Bondholders pursuant to
            Section 39.309 of the Texas Electric Choice Plan or any Lien created
            by the Issuer under the Basic Documents), have been taken or made.

      Section 3.09 Solvency. After giving effect to the sale of the Transition
Property hereunder, the Seller:

            (i) is solvent and expects to remain solvent,

            (ii) is adequately capitalized to conduct its business and affairs
      considering its size and the nature of its business and intended purposes,

            (iii) is not engaged and does not expect to engage in a business for
      which its remaining property represents an unreasonably small portion of
      its capital,

                                      -6-
<PAGE>

            (iv) reasonably believes that it will be able to pay its debts as
      they come due, and

            (v) is able to pay its debts as they come due and does not intend to
      incur, or believe that it will incur, indebtedness that it will not be
      able to repay at its maturity.

      Section 3.10 The Financing Order.

            (a) The Financing Order was issued by the Texas Commission on March
      16, 2005 in accordance with the Texas Electric Choice Plan; the Financing
      Order and the process by which it was issued comply with all applicable
      laws, rules and regulations of the State of Texas and the federal laws of
      the United States, and the Financing Order is final, non-appealable and in
      full force and effect.

            (b) As of the date of issuance of the Transition Bonds, the
      Transition Bonds will be entitled to the protections provided by the Texas
      Electric Choice Plan and the Financing Order, and the Financing Order and
      the Transition Charges authorized therein will have become irrevocable and
      not subject to reduction, impairment or adjustment by further action of
      the Texas Commission, except as permitted by Section 39.307 of the Texas
      Electric Choice Plan, and the Issuance Advice Letter has been filed in
      accordance with the Financing Order. The Texas Commission has not issued
      any order prior to noon on the fourth business day after submission of the
      Issuance Advice Letter that the Transition Bonds do not comply with
      Ordering Paragraph Four of the Financing Order and the initial Transition
      Charges and the final terms of the Transition Bonds set forth in the
      Issuance Advice Letter have become effective.

      Section 3.11 State Action.

            (a) Under the Texas Electric Choice Plan, the State of Texas has
      pledged that it will not take or permit any action that would impair the
      value of the Transition Property or, except as permitted in Section 39.307
      of the Texas Electric Choice Plan, reduce, alter or impair the Transition
      Charges until the principal, interest and premium, if any, and any other
      charges incurred and contracts to be performed in connection with the
      Transition Bonds, have been paid and performed in full.

            (b) Under the laws of the State of Texas and the federal laws of the
      United States, the State of Texas could not constitutionally take any
      action of a legislative character, including the repeal or amendment of
      the Texas Electric Choice Plan, which would substantially limit, alter or
      impair the Transition Property or other rights vested in the Transition
      Bondholders pursuant to the Financing Order, or substantially limit,
      alter, impair or reduce the value or amount of the Transition Property,
      unless such action is a reasonable exercise of the State of Texas'
      sovereign powers and of a character reasonable and appropriate to the
      important public purpose justifying such action, and, under the takings
      clauses of the State of Texas and United States Constitutions, the State
      of Texas could not repeal or amend the Texas Electric Choice Plan or take
      any other action in contravention of its pledge quoted above without
      paying just compensation to the Transition Bondholders, as determined by a
      court of competent jurisdiction, if doing so

                                      -7-
<PAGE>

      would constitute a permanent appropriation of a substantial property
      interest of the Transition Bondholders in the Transition Property and
      deprive the Transition Bondholders of their reasonable expectations
      arising from their investments in the Transition Bonds; however, there is
      no assurance that, even if a court were to award just compensation, it
      would be sufficient to pay the full amount of principal of and interest on
      the Transition Bonds.

      Section 3.12 No Court Order. There is no order by any court providing for
the revocation, alteration, limitation or other impairment of the Texas Electric
Choice Plan, the Financing Order, the Issuance Advice Letter, the Transition
Property or the Transition Charges or any rights arising under any of them or
that seeks to enjoin the performance of any obligations under the Financing
Order.

      Section 3.13 Approvals Concerning the Transition Property. Under the laws
of the State of Texas and the federal laws of the United States, no other
approval, authorization, consent, order or other action of, or filing with any
Governmental Authority is required in connection with the creation or transfer
of the Seller's rights and interests under the Financing Order and the Issuer's
purchase of the Transition Property from the Seller, except those that have been
obtained or made.

      Section 3.14 Assumptions. Based on information available to the Seller on
the date hereof, the assumptions used in calculating the Transition Charges in
the Issuance Advice Letter are reasonable and made in good faith; however,
notwithstanding the foregoing, THE SELLER MAKES NO REPRESENTATION OR WARRANTY,
EXPRESS OR IMPLIED, THAT AMOUNTS ACTUALLY COLLECTED ARISING FROM THE TRANSITION
CHARGES WILL IN FACT BE SUFFICIENT TO MEET THE PAYMENT OBLIGATIONS ON THE
TRANSITION BONDS OR THAT THE ASSUMPTIONS USED IN CALCULATING SUCH TRANSITION
CHARGES WILL IN FACT BE REALIZED.

      Section 3.15 Creation of the Transition Property.

            (a) Upon the effectiveness of the Issuance Advice Letter, the
      transfer of the Seller's rights and interests under the Financing Order
      related to the Transition Bonds and the Issuer's purchase of the
      Transition Property from the Seller pursuant to this Agreement, the
      Transition Property will constitute a present property right.

            (b) Upon the effectiveness of the Issuance Advice Letter, the
      transfer of the Seller's rights and interests under the Financing Order
      and the Issuer's purchase of the Transition Property from the Seller
      pursuant to this Agreement, the Transition Property includes:

                  (1)   the right to impose, collect and receive the Transition
                        Charges, including the right to receive Transition
                        Charges in amounts and at times sufficient to pay
                        principal and interest on the Transition Bonds,

                  (2)   all rights and interest of the Seller under the
                        Financing Order,

                                      -8-
<PAGE>

                  (3)   the rights to file for periodic adjustments of the
                        Transition Charges as provided in the Financing Order,
                        and

                  (4)   all revenues and collections resulting from Transition
                        Charges.

            (c) Upon the effectiveness of the Issuance Advice Letter, the
      transfer of the Seller's rights and interests under the Financing Order
      and the Issuer's purchase of the Transition Property from the Seller on
      such Transfer Date pursuant to this Agreement, the Transition Property
      will not be subject to any Lien created by a previous indenture.

      Section 3.16 Prospectus. As of the date hereof, the information describing
the Seller under the caption "The Servicer of the Transition Property" in the
Prospectus is true and correct in all material respects.

      Section 3.17 Nature of Representations and Warranties. The representations
and warranties set forth in Section 3.08 and Section 3.10 through Section 3.16,
insofar as they involve conclusions of law, are made not on the basis that the
Seller purports to be a legal expert or to be rendering legal advice, but rather
to reflect the parties' good faith understanding of the legal basis on which the
parties are entering into this Agreement and the other Basic Documents and the
basis on which the Transition Bondholders are purchasing the Transition Bonds,
and to reflect the parties' agreement that, if such understanding turns out to
be incorrect or inaccurate, the Seller will be obligated to indemnify the Issuer
and its permitted assigns (to the extent required by and in accordance with
Section 5.01), and that the Issuer and its permitted assigns will be entitled to
enforce any rights and remedies under the Basic Documents on account of such
inaccuracy to the same extent as if the Seller had breached any other
representations or warranties hereunder.

                                   ARTICLE IV

      Section 4.05 Compliance With Law. The Seller shall comply with its
organizational or governing documents and all laws, treaties, rules, regulations

            required in connection with the SEC's administration of the 1935
            Act,

      Financing Order or the Texas Electric Choice Plan or applicable tariff
      shall discharge such Person's obligations in respect of the Transition
      Property to the extent of such payment, notwithstanding any objection or
      direction to the contrary by the Seller.

Commission or the State of Texas of any of their obligations or duties under the

by the Seller to the Issuer, and the Seller agrees to take such legal or
administrative actions, including defending against or instituting and pursuing
legal actions and appearing or testifying at hearings or similar proceedings, in
each case as may be reasonably necessary:

            (a) to protect the Issuer and the Transition Bondholders from
      claims, state actions or other actions or proceedings of third parties
      which, if successfully pursued, would result in a breach of any
      representation set forth in Article III; or

      any attempts to cause a repeal of, modification of or supplement to the
      Texas Electric Choice Plan, the Financing Order, the Issuance Advice
      Letter or the rights of Transition Bondholders by

                                      -11-

      legislative enactment or constitutional amendment that would be materially

outstanding, the Seller shall pay all material taxes, assessments and
governmental charges imposed upon it or any of its properties or assets or with
respect to any of its franchises, businesses, income or property before any
penalty accrues thereon if the failure to pay any such taxes, assessments and
governmental charges would, after any applicable grace periods, notices or other
similar requirements, result in a Lien on the Transition Property; provided that
no such tax need be paid if the Seller or any of its Affiliates is contesting
the same in good faith by appropriate proceedings promptly instituted and
diligently conducted and if the Seller or such Affiliate has established
appropriate reserves as shall be required in conformity with generally accepted
accounting principles.

      Section 4.09 Filings Pursuant to Financing Order. The Seller shall comply
with all filing requirements imposed upon the Seller in its capacity as such by
