                     CONVEYANCE OF THE TRANSITION PROPERTY

     Section 2.01 Conveyance of the Initial Transition Property.

          (a)     In consideration of the Issuer's payment to or upon the order
     of the Seller of $738,197,000 (the "Initial Purchase Price") by wire
     transfer of funds immediately available on the date hereof to Seller's
     account no.          at         ,routing transit ABA #         , 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 Initial Transfer Date whereupon such rights and
     interests under the Financing Order shall become the Initial Transition
     Property (such sale, transfer, assignment, setting over and conveyance of
     the Initial 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 related to the Initial Transition Property, as the
     same may be adjusted from time to time). Such sale, transfer, assignment,
     setting over and conveyance of the Initial 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 Initial Purchase
     Price and the execution and delivery of this Agreement and the related 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
     Initial Transition Property.

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

                                       -2-

<PAGE>

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

          (d)     The Seller and the Issuer further agree that from time to
     time, the Seller may offer to sell, and the Issuer may purchase, the
     Seller's rights and interests under separate financing orders as of
     Subsequent Transfer Dates whereupon such rights and interests under
     subsequent financing orders shall become Subsequent Transition Property,
     subject to the satisfaction or waiver of the conditions specified in
     Section 2.02, in exchange for consideration to be agreed upon (the
     "Subsequent Purchase Price"). The Seller and the Issuer hereby agree that
     each such sale, transfer, assignment, setting over and conveyance of any
     Subsequent Transition Property shall include, to the fullest extent
     permitted by the Texas Electric Choice Plan, the right to impose, collect
     and receive the Transition Charges related to such Subsequent Transition
     Property, as the same may be adjusted from time to time. Such sale,
     transfer, assignment, setting over and conveyance of the Subsequent
     Transition Property is hereby 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, will be a true sale and is not a secured
     transaction and title, legal and equitable, will pass 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 applicable Subsequent Purchase Price and the execution and
     delivery of the related Bill of Sale, the sale, transfer and assignment to
     the Issuer thereunder shall be effective and the Seller shall have no
     right, title or interest in, to or under the Subsequent Transition Property
     which is the subject of such Bill of Sale.

          (e)     Notwithstanding the foregoing, in the event that any sale,
     transfer, assignment, setting over and conveyance of any 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 such Transition Property under Section 39.309 of the
     Texas Electric 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 such 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
Transition Property upon the Initial Transfer Date or any Subsequent Transfer
Date shall be subject to and conditioned upon the satisfaction or waiver of each
of the following conditions:

     warranties of the Seller in this Agreement shall be true and correct and no
     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;

     Transition Property to be purchased on such date, free and clear of all

     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 or a separate financing
     order, as the case may be, and the UCC);

          (v)    in the case of any sale of Subsequent Transition Property only,
     the Seller shall have provided the Issuer and each Rating Agency with a
     notice specifying the Subsequent Transfer Date for such Subsequent
     Transition Property not later than thirty (30) days prior to the Subsequent
     Transfer Date;

          (vi)   the Seller shall have delivered to each Rating Agency and to

     As of each Transfer Date, the Seller makes the following representations
and warranties on which the Issuer has relied and will rely in acquiring the
Transferred Transition Property. The following representations and warranties
are made under existing law as in effect as of the applicable Transfer Date. The
Seller shall not be in breach of any representation or warranty herein as a
result of a change in law (which does not include a final, non-appealable
judicial holding by a court of competent jurisdiction that any provision of the
Texas Electric Choice Plan relevant to securitization is unconstitutional)
occurring after the applicable Transfer Date. The representations and warranties
shall survive the sale of the Transferred Transition Property to the Issuer and
the pledge thereof on each Transfer Date to the Indenture Trustee pursuant to
the Indenture.

     Section 3.01 Organization and Good Standing. The Seller is a corporation
duly organized and in good standing under the laws of the State of Texas, with
corporate 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 corporation 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 corporate 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 corporate 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, whereupon such
rights and interests will become the Transition Property, to the Issuer, and the
Seller has duly authorized such sale and assignment to the Issuer by all
necessary corporate action; and the execution, delivery and performance of this
Agreement have been duly authorized by the Seller by all necessary corporate
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

                                       -5-

<PAGE>

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 default under, the
articles of incorporation or by-laws 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 or agreement or other instrument; 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 October 17, 2001 and the related prospectus supplement dated
October 17, 2001 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:

               (i)   asserting the invalidity of this Agreement, any of the
       other Basic Documents, the Transition Bonds, the Texas Electric Choice
       Plan or 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 the Seller for federal or state income, gross receipts or
       franchise tax purposes.

       Section 3.07  Approvals. Except for continuation filings under the UCC
and other filings under the Texas Electric Choice Plan and the UCC, 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. The Issuance Advice Letter has been filed in accordance
with the Financing Order.

     Section 3.08 The Transition Property.

              (a) Information. Subject to Section 3.15, all information, as
     amended or supplemented from time to time prior to the date this
     representation is made, provided by the Seller to the Issuer with respect
     to the Transferred Transition Property (including the Financing Order and
     the Issuance Advice Letter) is correct in all material respects.

              (b) Effect of Transfer. Each 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 such
     rights and interests shall become the Transition Property; upon execution
     and delivery of this Agreement and the related Bill of Sale and payment of
     the Initial Purchase Price or Subsequent Purchase Price, as applicable, the
     Seller will have no right, title or interest in, to or under the
     Transferred Transition Property; and such Transferred 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
                  applicable Transfer Date.

                  (ii)  On the Transfer Date, immediately upon the sale
                  hereunder, such Transferred 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 first priority perfected
                  ownership interest in the Transferred Transition Property and
                  to grant to the Indenture Trustee a first priority perfected
                  security interest in such Transferred Transition Property,
                  free and clear of all Liens of the Seller or anyone else, have
                  been taken or made.

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

             (i)  is solvent and expects to remain solvent,

                                       -7-

<PAGE>

             (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,

             (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)   Each provision of the Texas Electric Choice Plan relevant to
     securitization is valid and constitutional under the Texas and United
     States Constitutions; the Financing Order as issued on May 31, 2000 and as
     interpreted by the Texas Commission on September 18, 2001 has been issued
     by the Texas Commission 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 and the Financing Order is final and
     non-appealable and in full force and effect.

             (b)   As of the date of issuance of any Series of the Transition
     Bonds, the Transition Bonds of that Series (including those issued in
     respect of Subsequent Transition Property) 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 relating to the Transferred Transition Property to
     be sold on such date has been filed in accordance with the Financing Order.
     The Texas Commission has not issued any order prior to the third business
     day after submission of the Issuance Advice Letter that the Transition
     Bonds do not comply with Ordering Paragraph 5 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.

                                       -8-

<PAGE>

              (b)  Under the laws of the State of Texas and 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 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 Transferred
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. 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 Transferred Transition Property from the Seller, except those
that have been obtained or made.

     Section 3.14  No Proceedings Concerning the Texas Electric Choice Plan.
Except as disclosed in the Prospectus, there are no proceedings pending, and to
the best of the Seller's knowledge, (i) there are no proceedings threatened and
(ii) there are no investigations pending or threatened, before any Governmental
Authority having jurisdiction over the Issuer or the Seller or their respective
properties challenging the Texas Electric Choice Plan or the Financing Order.

     Section 3.15  Assumptions. 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 the assumptions used in
calculating such Transition Charge will in fact be realized.

                                       -9-

             (a)   Upon the effectiveness of the Issuance Advice Letter and 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 Transferred Transition Property constitutes a
     present property right.

             (b)   Upon the effectiveness of the Issuance Advice Letter and the
     transfer of the Seller's rights and interests under the Financing Order and

                         Charges authorized in the Financing Order, including,
                         without limitation, the right to receive Transition
                         Charges in amounts and at times sufficient to pay
                         principal and interest on the Transition Bonds and make
                         deposits to the overcollateralization subaccount,

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

                    (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 and the
     transfer of the Seller's rights and interests under the Financing Order and
     the Issuer's purchase of the Transferred Transition Property from the
     Seller on such Transfer Date pursuant to this Agreement, the Transferred
     Transition Property is not subject to any Lien created by a previous
     indenture.

     Section 3.17   Prospectus. As of the date hereof, the information
describing the Seller under the caption "Reliant Energy" and the caption "The
Servicer of the Transition Property" in the Prospectus is true and correct in
all material respects.

     Section 3.18   Conversion to a Limited Liability Company. The conversion of
the Seller into a Texas limited liability company will not:

             (a)    interrupt the Seller's existence,

                                      -10-

<PAGE>
               (b) affect the Seller's rights, title and interests in its real
                   estate and other property or its power and authority to
                   perform its obligations under this Agreement, the Servicing
                   Agreement or the other Basic Documents,

               (c) impair or diminish the liabilities and obligations of the
                   Seller, including, without limitation, its obligations under
                   this Agreement or any other Basic Document, or

               (d) result (i) in the breach of any representation or warranty
                   made pursuant to this Article III or (ii) after notice or
                   lapse of time, or both, in a Servicer Default.


     Section 3.19 Nature of Representations and Warranties. The representations
and warranties set forth in Section 3.08 and Section 3.10 through Section 3.18,
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

                            COVENANTS OF THE SELLER

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

          Letter or the rights of Transition Bondholders by legislative
          enactment or constitutional amendment that would be adverse to the
          Issuer, the Indenture Trustee or the Transition Bondholders.

to the Seller from amounts on deposit in the collection account as an operating
expense in accordance with the terms of the Indenture. The Seller's obligations

after any applicable grace periods, notices or other similar requirements,
result in a Lien on the Transferred Transition Property; provided that no such
tax need be paid if the Seller or one 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

     Person from and against, any and all taxes (other than any taxes imposed on
     Transition Bondholders solely as a result of their ownership of Transition
     Bonds) that may at any time be imposed on or asserted against any such
     Person under existing law as of any Transfer Date as a result of the sale
     and assignment of the Seller's rights and interests under the Financing
     Order by the Seller to the Issuer, the acquisition or holding of the
     Transferred Transition Property by the Issuer or the issuance and sale by
     the Issuer of the Transition Bonds, including any sales, gross receipts,
     general corporation, personal property, privilege, franchise or license
     taxes, but excluding any taxes imposed as a result of a failure of such
     Person to properly withhold or remit taxes imposed with respect to payments
     on any Transition Bond, in the event and to the extent such taxes are not
     recoverable as Qualified Costs, it being understood that the Transition
     Bondholders shall be entitled to enforce their rights against the Seller

     their benefit by the Indenture Trustee.

          (c) The Seller shall indemnify the Issuer and the Indenture Trustee,
     for itself and on behalf of the Transition Bondholders, and each of their

     amount of any deposits to the Issuer required to have been made in
     accordance with the terms of the Basic Documents which are not made when so
     required, in each case as a result of the Seller's breach of any of its
     representations, warranties or covenants contained in this Agreement.

          (d) The Seller shall indemnify the Issuer and the Indenture Trustee,
     for itself and on behalf of the Transition Bondholders, and each of their
     respective officers, directors, managers, employees and agents for, and
     defend and hold harmless each such Person from and against, any and all
     liabilities, obligations, claims, actions, suits or payments of any kind
     whatsoever that may be imposed on or asserted against any such Person
     (other than any liabilities, obligations or claims for or payments of
     principal of or interest on the Transition Bonds) together with any
     reasonable costs

     Seller's breach of any of its representations, warranties or covenants
     contained in this Agreement.

          (e)  The indemnification obligations of the Seller under this Section
     5.01 shall rank pari passu with all other general unsecured obligations of

     resignation or removal of the Indenture Trustee and the termination of
     this Agreement and shall include reasonable fees and expenses of
     investigation and litigation (including reasonable attorneys' fees and
     expenses). The Seller shall not indemnify any party under this Section 5.01
     for any changes in law (which does not include a final, non-appealable
     judicial holding by a court of competent jurisdiction that any provision of
     the Texas Electric Choice Plan relevant to securitization is
     unconstitutional) after the Transfer Date.

          (g)  The Seller shall pay any and all taxes levied or assessed upon
     all or any part of the Issuer's property or assets based on existing law as
     of the Transfer Date.
