             APPLICATION OF CENTERPOINT ENERGY HOUSTON ELECTRIC, LLC
        ON BEHALF OF CENTERPOINT ENERGY TRANSITION BOND COMPANY, LLC FOR
                    A STANDARD TRUE-UP OF TRANSITION CHARGES

                             DESCRIPTION OF TRUE-UP

                                   BACKGROUND

In accordance with the Financing Order adopted in Application of Reliant Energy,
Incorporated for Financing Order to Securitize Regulatory Assets and Other
Qualified Costs, Docket No. 21665(1) and in conformance with the Issuance Advice
Letter of October 18, 2001 CenterPoint Energy Transition Bond Company, LLC(2)
securitized certain regulatory assets and other qualified costs on October 24,
2001. CenterPoint Energy Houston Electric, LLC (Company) is the servicer for
CenterPoint Energy Transition Bond Company, LLC to bill, collect, receive and
adjust Transition Charges imposed pursuant to Schedule TC. Schedule TC sets out
the rates and terms and conditions under which Transition Charges will be billed
and collected. Schedule TC is contained in CenterPoint Energy Houston Electric,
LLC's tariff at Sheet No. 6.7.

                                PURPOSE OF FILING

The Company is filing for an Annual Standard True-up of TC Charges in accordance
with Schedule TC to be effective November 1, 2003.

                                 ANNUAL TRUE-UP

Schedule TC, Section 8, Standard True-up For Adjustment of Transition Charges,
provides that Transition Charges will be adjusted annually effective November
1st to ensure that the expected collection of Transition Charges is adequate to
pay principal and interest on the Transition Bonds when due pursuant to the
expected amortization schedule, pay as due all other qualified costs and to fund
the overcollateralization account to the required level.

Schedule TC Section 8, Part A: True-up Adjustment Procedure For Standard and
Interim True-ups provides that Annual Adjustments will be filed 15 days prior to
the effective date of the Adjusted Transition Charges unless an adjustment to
the Regulatory Asset Allocation Factors ("RAAF") is required under Section 6
(including Intra-Group Allocation Adjustments under Part D of Section 6) in
which case the annual adjustment will be filed not later than 90 days prior to
the effective date. The Company has determined that an adjustment to the RAAFs
is required under Section 6 of Schedule TC and therefore is filing not later
than 90 days prior to the November 1, 2003 effective date of the Adjusted
Transition Charges.

                              ADJUSTMENTS TO RAAFs

The RAAFs are subject to adjustment using the procedures provided at Section 6
of Schedule TC. Any adjustment required under Section 6 will be made effective
on the date of an annual Standard True-up Adjustment.

 ADJUSTMENT TO RAAFs DUE TO LOAD LOSS QUALIFYING UNDER UTILITIES CODE 39.262(k)

Schedule TC, Section 6, Part A provides that the RAAFs shall be adjusted
consistent with the Utilities Code 39.262(k) to reflect the loss of loads due to
operations of facilities that are "Eligible Generation" as defined in PUC Subst.
Rule 25.345 (c) (2) ("Eligible Generation") except that Part A shall not apply
to, and the term "Eligible Generation" shall not include, load loss due to
installation and operation of small power production facilities with a rated
capacity of 10 megawatts or less. Any adjustments required under Section 6 Part
A will be calculated under the terms of Schedule TC:

         Step 1 - The Company will determine the amount of service provided
         during the twelve months ended April 30, 1999 that has been replaced by
         Eligible Generation (excluding amounts reflected in a prior adjustment
         under this Part A) and sum the losses by Transition Charge Class

         Step 2 - The Company will recalculate the RAAFs for all Transition
         Charge Classes using the spreadsheet and data used to compute the
         initial RAAFs but reducing the demand allocation factors for each
         Transition Charge class to reflect the cumulative losses for that class
         as calculated under Step 1 (including losses for which RAAF adjustments
         were made in prior years). No other changes to the spreadsheet or data
         used to compute the initial RAAFs will be made. Appendix A to Schedule
         TC contains the spreadsheet and data used to compute the initial RAAFs.

         Step 3 - An Adjusted Group Allocation Percentage for each TC Group is
         then calculated as the sum of the Adjusted RAAFs (computed under Step
         2) for all Transition Charge Classes within the TC Group.

The Company, in its previous Standard True-up filing(3), adjusted the RAAFs to
eliminate retail loads served by six facilities that qualified as Eligible
Generation under the Commission's rules. The Commission in Docket No. 26402
approved a settlement finding that the Company's proposed adjustments for the
customers of the six facilities was appropriate(4). In this filing the Company
has continued to treat the retail customers of those six facilities as eligible
for reduced transition charges under Utilities Code 39.262(k).The Commission's
final order in Docket 26402 also found that one additional facility qualified as
Eligible Generation under the Commission's rules and that the retail customer of
that facility (Bayer Corporation) was eligible for reduced Transition Charges
under Utilities Code 39.262(k)(5). The Company has adjusted the RAAFs to reflect
the Commission's determination that Bayer Corporation is eligible for reduced
Transition Charges.

The Company has recalculated the RAAFs according to the procedures described
above. The adjusted RAAFs effective November 1, 2003 are calculated at Appendix
A of this filing.

           ADJUSTMENT TO RAAFs NOT ATTRIBUTABLE TO ELIGIBLE GENERATION

Schedule TC, Section 6, Parts B and C provide that under certain circumstances,
generally related to a load loss in a particular TC Class or TC Group that
exceeds prescribed thresholds when compared to prior base periods, the RAAFs
will be adjusted. The Company has determined that no adjustments are required
under Parts B and C. The Company has also determined that no adjustments to the
RAAFs are required under Section 6, Part D, which provides for adjustments if
the Commission enters an order pursuant to Section 39.253(f) of the Utilities
Code. The Utilities Code at Section 39.253(f) provides details for a change to
the allocation methodology for stranded cost if stranded cost of investor-owned
utilities exceeds $5 billion on a statewide basis.

                    6.1.1.7- SCHEDULE TC- TRANSITION CHARGES

SECTION 1: APPLICABILITY

This schedule sets out the rates and terms and conditions under which Transition
Charges will be billed and collected by CenterPoint Energy Houston Electric, LLC
(Company), any successor servicer(s) and any retail electric providers (REP) or
collection agents billing or collecting Transition Charges on behalf of
CenterPoint Energy Transition Bond Company, LLC (SPE). The Transition Charges
were authorized by the Financing Order approved by the Public Utility Commission
of Texas (Commission) in Docket No. 21665 on May 31, 2000 (Financing Order).
Pursuant to terms of the Financing Order and the requirements of Section 39.301
et seq. of the Texas Utilities Code, all of the Company's rights under the
Financing Order, including the right to bill and collect Transition Charges and
to adjust Transition Charges pursuant to this Schedule TC, were transferred to
the SPE in connection with the issuance of transition bonds. The rights
transferred to the SPE are "transition property" of the SPE (as defined in
Section 39.304 of the Utilities Code). On the effective date of this Schedule
TC, the Company will act as servicer on behalf of the SPE to bill, collect,
receive and adjust Transition Charges imposed pursuant to this Schedule TC.
However, the SPE may select another party to serve as servicer or the Company
may resign as servicer in accordance with terms of the Servicing Agreement and
the Financing Order. A successor servicer selected under these conditions will
assume the obligations of the Company as servicer under this schedule. As used
in this schedule, the term "Servicer" includes any successor servicer. All
actions by the Company under this Schedule TC, including collection of
Transition Charges, will be undertaken solely in its role as servicer under the
Servicing Agreement between the Company and the SPE dated October 24, 2001.

This schedule is applicable to:

         1.       Retail customers located within the Company's certificated
                  service area as it existed on May 1, 1999 who receive electric
                  transmission and/or distribution service either directly from
                  the Company or through a REP served by the Company and to the
                  facilities, premises and loads of such retail customers;

         2.       Retail customers located within the Company's certificated
                  service area as it existed on May 1, 1999 who are presently
                  receiving transmission and/or distribution service from
                  another utility, electric cooperative or municipally owned
                  utility (T or D Provider), and whose request to change service
                  to the other T or D Provider was made after May 1, 1999;

         3.       Retail customers located within the Company's certificated
                  service area as it existed on May 1, 1999 and who are served
                  by New On-Site Generation. New On-Site Generation means "New
                  On-Site Generation" as defined in Section 25.345 (c) (1) of
                  the Commission's Substantive Rules.

         4.       REPs that serve retail customers located within the Company's
                  certificated service area as it existed on May 1, 1999.

         5.       Any other entity which, under the terms of the Financing Order
                  or the Utilities Code, may be obligated to pay, bill, collect,
                  or adjust the Transition Charges.

         6.       Effective January 1, 2002, this schedule will also become
                  applicable to public retail customers located within the
                  Company's certificated service area as it existed on May 1,
                  1999 who purchase power from the General Land Office as
                  provided for in the Utilities Code, Section 35.102.

"Retail customers", as used in 1, 2, and 3 above, includes all "public retail
customers" as defined in Utilities Code, Section 35.101 except for those public
retail customers included in 6 above.

SECTION 2: CHARACTER OF TRANSITION CHARGES

Transition Charges are non-bypassable charges. All Transition Charges other than
those applicable to New On-Site Generation are computed and paid on the basis of
individual end-use retail customer consumption or demand. In accordance with
Utilities Code Section 39.252 (b) and Section 25.345 (i) (3) of the Commission's
Substantive Rules, the Transition Charges applicable to use of New On-Site
Generation that results in a "material reduction" of the customer's use of
energy delivered through the Company's transmission and distribution facilities
(as defined in Section 25.345 (i) (4) of the Commission's Substantive Rules) are
computed and paid based on the output of the on-site generation used to meet the
internal electric requirements of the customer. Customers with New On-Site
Generation will also be required to pay the Transition Charges applicable to
energy actually delivered to the Customer through the Company's facilities.
Individual end-use retail customers are responsible for paying Transition
Charges billed to them in accordance with the terms of this Schedule TC whether
the charges are billed directly by Servicer or are included in the bills
submitted to the customer by an REP or another entity. Payment is to be made to
the entity that bills the customer in accordance with the terms of the Servicing
Agreement and the Financing Order. The billing entity may be the Company, a
successor servicer, an REP or an entity designated to collect Transition Charges
in place of the REP.

Prior to January 1, 2002, the Transition Charges for retail customers served
directly by the Company are included in the otherwise applicable Company rates
under which the customer takes service and will not increase the total amounts
paid by retail customers. Prior to and after January 1, 2002, the Transition
Charges to retail customers who are not served directly by the Company
(including retail customers who take service from REPs after the beginning of
customer choice and participants in a Customer Choice Pilot Project as provided
in Utilities Code Section 39.104) but whose facilities, premises, and loads are
subject to Transition Charges billed and collected pursuant to this Schedule TC,
are separate charges to be paid in addition to

any other applicable charges for services received. After January 1, 2002,
although the Transition Charges are separate charges, they may be included
within other charges of the billing entity.

The REP or entity designated to collect Transition Charges in place of the REP
will pay Transition Charges (less an allowance for charge-offs calculated
pursuant to this Schedule TC) to Servicer in accordance with the requirements of
the Financing Order and this Schedule TC whether or not it has collected the
Transition Charges from its customers. To the extent that the REP's actual
charge-offs differ from the charge-off allowance, adjustments will be made
pursuant to this Schedule TC. The REP will have no right to reimbursement other
than as expressly set out in this Schedule TC.

Servicer will remit collections to the SPE in accordance with the terms of the
Servicing Agreement.

SECTION 3: TERM

This Schedule TC is effective beginning on the date the transition bonds are
issued. Schedule TC will remain in effect as provided in the Financing Order
until the Transition Charges collected and remitted to the SPE are sufficient to
satisfy all obligations of the SPE to pay principal and interest on the
transition bonds (as due over the 12 year term of the transition bonds) and to
pay all other qualified costs as provided in the Financing Order. However, in no
event will the Transition Charges be billed for service provided after 15 years
from issuance of the transition bonds, or sooner if the transition bonds are
paid in full at an earlier date. This Schedule TC is irrevocable.

SECTION 4: TRANSITION CHARGE CLASSES

Transition Charges are calculated and applied by Transition Charge Class. There
are 15 Transition Charge Classes, nine of which are Capped Classes. The
Transition Charge Classes are defined as follows:

         RESIDENTIAL CLASS: The Residential Class is made up of (i) every
         customer that is served under Company rate schedule RS or RTD, and (ii)
         every customer that was served under Company rate schedule RS or RTD on

         Company on a base rate tariff in effect on September 1, 1999 pursuant
         to Utilities Code Section 39.052 (a), (herein referred to as a "frozen
         rate schedule"), and (iii) each new customer that was not served by the
         Company under any frozen rate schedule, but is the type of customer
         which, if it had been served by the Company under frozen rate schedules
         would have qualified for service under the Company's rate schedules RS
         or RTD.

         MGS CLASS: The MGS Class is made up of (i) every customer that is
         served under Company rate schedule MGS, and (ii) every customer that

         service from the Company on a frozen rate schedule, and (iii) each new
         customer that was not served by the Company under any frozen rate
         schedule, but is the type of customer which, if it had been served by

         service under the Company's rate schedule MGS and whose demand is
         estimated by the Company to be less than 400 kVa. This class includes
         customers served under Rider GLTC. Customers served under rate
         schedules EIS, HVP and CSB are included in the MGS class if the
         customer's contract for service provides that the MGS rate is the basis
         for pricing.

         LGS CLASS: The LGS Class is made up of (i) every customer that is
         served under rate schedule LGS, and (ii) every customer that was served

         discontinued taking service from the Company on a frozen rate schedule,
         and (iii) each new customer that was not served by the Company under
         any frozen rate schedule, but is the type of customer which, if it had
         been served by the Company under a frozen rate schedule would have
         qualified for service under the Company's rate schedules LGS and whose
         demand as estimated by the Company, if served at less than 60,000
         volts, is 400 kVa or greater; or if served at 60,000 volts or greater,
         is at least 400 kVa but less than 2,000 kVa. This class includes
         customers served under Rider SEI. Customers served under rate schedules
         EIS, HVP and CSB are included in the LGS class if the customer's
         contract for service provides that the LGS rate is the basis for
         pricing.

         LOS-A CLASS: The LOS-A Class is made up of (i) every customer that is
         on rate schedule LOS-A, and (ii) every customer that was served under

         service under the Company's rate schedule LOS-A and has a demand as
         estimated by the Company of 2,000 kVa or greater. Customers served
         under rate schedules EIS and HVP are included in the LOS-A class if the

         a frozen rate schedule, and (iii) each new customer which was not
         served by the Company under any frozen rate schedule, but is taking
         outdoor lighting services which are provided on an unmetered basis
         using lighting fixtures controlled by photo-electric devices which
         would have qualified for service under the Company's frozen rate
         schedules SPL, MLS and MTA.

In addition to the six Transition Charge Classes described above, there will be
nine additional Transition Charge Classes, each of which is a capped class
("Capped Classes"). Each of the Capped Classes will be made up solely of
customers that actually received service from the Company during the 12-month
period ended April 30, 1999 under the Company rate schedule related to the
class. The nine Capped Classes, and the related rate schedule, are as follows:

</TABLE>

Each customer in one or more of the nine Capped Classes will be charged the
Transition Charges for the applicable class only for service the customer
actually receives during the billing period up to the Monthly Cap. The Monthly
Cap for each customer will be based on the amount of service the customer
received under the related rate schedule during the 12-month period ended April
30, 1999 and calculated as follows:

         (1)      For customers taking stand alone standby service (SBI and/or
         SES without other service), the Monthly Cap for SBI and SES will be the
         highest demand under the respective rate, during the 12-month period
         ended April 30, 1999. If a customer begins service under SES and/or SBI
         after April 30, 1999, the Monthly Cap for such customer's will be the
         highest demand under rate SES or SBI, as applicable, during the period
         from April 30, 1999 to January 1, 2002, if the customer provides the
         Company adequate documentation that (i) the additional load served
         on-site load normally served by the customer's on-site generation and
         (ii) the customer's on-site generation was out of service due to forced
         outage or maintenance. If the customer does not provide the required
         documentation, the additional load will be billed using the Transition
         Charges applicable to the LGS Class for distribution voltage customers
         or LOS-A Class for transmission voltage customers.

         (2)      For customers taking SBI and/or SES in combination with other
         services, the Transition Charge for additional load taken in excess of
         the Monthly Cap will be the Transition Charge for the LOS-A class
         restated and applied as a cents per KWh charge if the customer provides
         the Company adequate documentation that (i) the additional load was
         lawfully served without use of the Company's transmission and
         distribution facilities and (ii) the customer's on-site generation was
         out of service due to forced outage or maintenance. If the customer
         does not provide the required documentation, the additional load will
         be billed using the Transition Charges applicable to the LOS-A Class
         for transmission voltage customers applied on a kW basis.

         (3)      For any SCP customer that also receives service under another
         non-Capped Class, the SCP rate will have a Monthly Cap based on the
         amount of service the customer received under the SCP rate schedule
         during the 12-month period ended April 30, 1999. The Monthly Cap will
         be the customer's monthly maximum hourly kW under the SCP rate schedule
         during the peak hours as defined herein, summed for the 12-month period
         ended April 30, 1999 and divided by the number of months during which
         the customer actually consumed power under the SCP rate schedule.

         (4)      For all other customers in Capped Classes, the Monthly Cap
         will be the customer's monthly maximum hourly kW under the related rate
         schedule during the peak hours as defined herein, summed for the
         12-month period ended April 30, 1999 and divided by the number of
         months during which the customer actually consumed power under the rate
         schedule. For monthly service in excess of the Monthly Cap(s), the
         charge associated with customer's Transition Charge Class will apply.
         If the customer is served at distribution voltage and did not have
         service associated with one of the six non-capped Transition Charge
         Classes, the customer will be required to pay the Transition Charges
         applicable to the LGS Class for all monthly service in excess of its
         Monthly Cap. If the customer is served at transmission voltage and did
         not have service associated with one of the six non-capped Transition
         Charge Classes, the customer will be required to pay the Transition
         Charges applicable to the LOS-A Class for all monthly service in excess
         of its Monthly Cap.

The categories of service historically provided by the Company may cease to
exist after electric business activities are unbundled pursuant to Section
39.051 of the Utilities Code. Similarly, after the advent of customer choice
under Section 39.102 of the Utilities Code, retail customers will receive
service that may not only have different names, but may have different
characteristics than the service historically provided by the Company. The
classifications set out in the preceding paragraphs will be applied to determine
the Transition Charge applicable to each customer without regard to the
descriptions that may be used to describe the services provided to retail
customers.

PART A: ADJUSTMENTS DUE TO LOAD LOSS QUALIFYING UNDER UTILITIES CODE SECTION
39.262(k)

The RAAFs shall be adjusted consistent with the Utilities Code to reflect the
loss of loads due to operations of facilities that are "Eligible Generation" as
defined in PUC Subst. Rule 25.345 (c) (2) ("Eligible Generation") except that
this Part A shall not apply to, and the term "Eligible Generation" shall not
include, load loss due to installation and operation of small power production
facilities with a rated capacity of 10 megawatts or less. Any adjustments
required under this Part A will be calculated as follows:

         Step 1 - The Company will determine the amount of service provided
         during the twelve months ended April 30, 1999 that has been replaced by
         Eligible Generation (excluding amounts reflected in a prior adjustment
         under this Part A) and sum the losses by Transition Charge Class.

         Step 2 - The Company will recalculate the RAAFs for all Transition
         Charge Classes using the spreadsheet and data used to compute the
         initial RAAFs but reducing the demand allocation factors for each
         Transition Charge class to reflect the cumulative losses for that class
         as calculated under Step 1 (including losses for which RAAF adjustments
         were made in prior years). No other changes to the spreadsheet or data
         used to compute the initial RAAFs will be made. Appendix A to this
         Schedule TC contains the spreadsheet and data used to compute the
         initial RAAFs.

         Step 3 - An Adjusted Group Allocation Percentage for each TC Group
         shall then be calculated as the sum of the Adjusted RAAFs (computed
         under Step 2) for all Transition Charge Classes within the TC Group.

PART B: INTER-GROUP ADJUSTMENTS DUE TO CUMULATIVE LOAD LOSS NOT ATTRIBUTABLE TO
        ELIGIBLE GENERATION

In connection with each annual Standard True-up Adjustment, the Company will
compare the projected billing determinants being used to set Transition Charges
for each Transition Charge Class during the ensuing year to the billing
determinants in effect on January 1, 2002 (adjusted to exclude any billing
determinants attributable to Eligible Generation if any adjustment was made
under Part A after January 1, 2002) (such billing determinants as adjusted are
hereafter referred to as the "January 1, 2002 Base Billing Determinants"). The
RAAFs of all Transition Charge Classes in all TC Groups will be adjone or more
TC Groups experience load loss (calculated excluding load loss attributable to
Eligible Generation for which adjustments have been made under Part A but
including load loss attributable to small power production facilities of 10
megawatts or less) aggregating 50% or more on a cumulative basis when measured
against the January 1, 2002 Base Billing Determinants. The adjustments under
this Part B will be made using the following procedures:

Step 1:

For each TC Group, if CTCOL(G) /       Then, no RAAF adjustment will occur and
PBR(G) > or = 0.50                     any adjustment made in previous years
                                       under Part B shall be reversed

For each TC Group, if CTCOL(G) /       Then, a RAAF adjustment will be
PBR(G) < 0.50                          calculated pursuant to Steps 2 through 5.

Where:

       CTCOL(G) = cumulative test collections for group G = (SIGMA)CC(c)* FBU(c)
       for all classes (c) in Group (G)

       FBU(c) = forecasted billing determinants for class c

       CC(c)= cumulative test charge for class c = {RAAF(c)*PBR(T)}/ BBD(c)

       RAAF(c)= the RAAFs then in effect, or if an adjustment has been made
       under Part A, the adjusted RAAFs from Part A

       PBR(T)= total periodic billing requirement for upcoming period

       BBD(c)=base billing determinants (as measured on January 1, 2002) for
       class c

       PBR(G)= periodic billing requirement for group = (SIGMA)RAAF(c)* PBR(T)
       for all classes in G

Step 2:

For each TC Group in Step 1 where CTCOL(G) / PBR(G) < 0.50, a reduction amount
(RED(G)) will be calculated for group G where

         RED(G)= 0.5 (PBR(G) - CTCOL(G))

Step 3:

For all TC Groups, a reallocation amount for that group (RA(G)) shall be
calculated where:

                 RA(G) = GAP(G) * {(SIGMA)RED(G)} for all Groups

Where:

         GAP(G) = Group Allocation Percentage = (SIGMA)RAAF(c) for all classes
         in the group

Step 4:

For all TC groups a Group Allocation Percentage Adjustment (GAPA(G)) shall be
calculated where:

                        GAPA(G)= (RA(G)-RED(G)) / PBR(T)

Where:

                          (SIGMA)GAPA(G) = 0 for all G

Step 5:

For all TC classes, the RAAF adjustment for class c (RAAFA(c)) will be
calculated for use in calculating adjustments to the Transition Charges under
Section 8, Part A where

                      RAAFA(c)= GAPA(G) * (RAAF(c)/GAP(G))

PART C: INTER-GROUP ADJUSTMENTS DUE TO YEAR-OVER-YEAR LOAD LOSS NOT ATTRIBUTABLE
        TO ELIGIBLE GENERATION

In connection with each annual Standard True-up Adjustment, the Company will
compare the projected billing determinants being used to set Transition Charges
for each Transition Charge Class during the ensuing year to the forecasted
billing determinants used to develop the then currently effective Transition
Charges for the class minus the Eligible Generation load loss for the class
determined in Step 1 of Part A after the billing determinant for the currently
effective Transition Charges was determined (such adjusted amount is hereinafter
referred to as the "Prior Year Billing Determinant"). The RAAFs of all
Transition Charge Classes in all TC Groups will be adjusted if (i) one or more
TC Groups experience load loss (calculated excluding load loss attributable to
Eligible Generation for which adjustments have been made under Part A but
including load loss attributable to small power production facilities of 10
megawatts or less) of 10% or greater on a year-over-year basis when compared to
the Prior Year Billing Determinants or (ii) any TC Group for which an adjustment
was made under this Part C in one or more prior years experiences load growth
resulting in projected billing determinants for the current year at a level
which, if they had existed in one or more of such prior year(s) would have
resulted in no adjustment to RAAFs in such prior year(s). No reduction in RAAFs
will be made under this Part C for any TC Group for which a reduction amount was
computed under Step 5 of Part B. The adjustments under this Part C will be made
using the following procedures:

Step 1:

For each TC Group not adjusted under Part B,

If YTCOL(G) / PBR(G) > or = 0.90     Then, no RAAF adjustment will occur.

If YTCOL(G) / PBR(G) > 1.00          Then, no RAAF adjustment will occur and any
                                     prior year adjustments made under C will be
                                     reversed pursuant to step 6.

If YTCOL(G) / PBR(G) < 0.90          Then, a RAAF adjustment will be calculated
                                     pursuant to Steps 2 through 5.

Step 2:

For each TC Group in Step 1 where YTCOL(G) / PBR(G) < 0.90, a year to year
reduction amount (YRED(G)) shall be calculated where

                        YRED(G)= 0.9 (PBR(G) - YTCOL(G))

Step 3:

For all TC Groups, a year to year reallocation amount (YRA(G)) shall be
calculated where:

Where:

         GAP(G) = Group Allocation Percentage = (SIGMA)RAAF(c) for all classes
         in the group

For all TC groups a year to year group allocation percentage adjustment
(YGAPA(G)) shall be calculated where:

Where (SIGMA)GAPA(G) = 0 for all G

Step 6:

if{(SIGMA)(YC(c)*FBU(c))}/{(SIGMA)(YC(c)*FBU(c)(t-1))} > or = .90 (for all
classes in group G) then the adjustment made in year t shall be discontinued.

if{(SIGMA)(YC(c)*FBU(c))}/{(SIGMA)(YC(c)*FBU(c)(t-1))} < .90 (for all classes in
group G) then the adjustment made in year t carries forward.

Where FBU(c)(t-1) is the forecasted billing determinants from the year prior to
the year an adjustment was made adjusted to reflect any adjustments made under
part A between year t-1 and the current year.

PART D: ADJUSTMENTS TO BASE CLASS ALLOCATIONS

The methodology used to allocate qualified costs and determine Transition
Charges shall not be changed except in the limited circumstance described in
this paragraph. If, but only if, the Commission enters an order pursuant to
Section 39.253 (f) of the Utilities Code ("Stranded Cost Allocation Order") that
(A) requires the Company to allocate stranded costs in a manner which complies
with that section and is different from the methodology used for allocation and
collection of Transition Charges under the Financing Order in Docket No. 21665,
and (B) also determines that it is necessary to adjust the initial RAAFs to
comply with the requirements of Section 39.253 (f), the Company will recalculate
the initial RAAFs to comply with the requirements of such order and will also
recalculate all adjustments which have been made pursuant to Parts A, B, C, and
D of this Section in order to recalculate the Adjusted RAAFs after giving effect
to the revised starting point. Within 45 days after the Stranded Cost Allocation
Order becomes final and is not subject to appeal, Servicer, on behalf of the
SPE, will file recomputed Transition Charges reflecting the effect of changing
the initial RAAFs. Any changes in Transition Charge resulting from a change in
the initial RAAFs under this paragraph shall be made prospectively from the date
recomputed Transition Charges become effective which effective date shall be 30
days after the recomputed Transition Charges are filed at the Commission.
Transition Charges for services rendered prior to such effective date will not
be changed. Future changes to the RAAFs underlying the recomputed Transition
Charges, if necessary under Parts A - D of this Section 6 will be computed
pursuant to this Section 6.

SECTION 7: TRANSITION CHARGES

The Transition Charges to be applied beginning on the effective date of this
Schedule TC are set out below. Transition Charges to be applied in subsequent
periods (Adjusted Transition Charges) will be determined in the manner described
in Section 8.

The Transition Charges shall be applied on a kW basis for all service provided
at Transmission voltage and for all service provided to Capped Classes and to
any LGS customer that also receives SES-Distribution service. The kW to be used
in calculating the bill for those customers obligated to pay on a kW basis will
be the highest kW measured over a one hour period occurring on weekdays (Monday
through Friday) during the sixteen hours beginning with and including the hour
that ends at seven (a.m.) (07:00) and extending until the hour that ends at ten
p.m. (22:00), local time (central standard or central daylight saving time, as
appropriate).

The Transition Charges shall be applied on a kVa basis for all service provided
at distribution voltage (other than service at distribution voltage to Capped
Classes or to LGS customers that also receive SES-Distribution service) and
whose kVa is greater than 10 kVa in the billing month. The kVa will be the
highest kVa measured over a 15 minute period during the month if the metering
equipment has indicators for measuring and recording only the highest demand
during the billing period, otherwise if the metering equipment measures and
records continuously for all 15 minute periods the kVa will be the average of
the 4 highest 15 minute periods measured during the billing period. If the
demand meters used to meter service to a customer measure service is on a kW
basis instead of a kVa basis or measure in intervals different than 15 minutes
e.g. 5, 10, 30 minutes, the transition charge to the customer will be based on
the kW with the interval measurement period closest to a 15 minute period.

Transition Charges will be applied on a kWh basis for those customers with
watt-hour meters and those customers with demand meters whose measured demand is
10 kVa or less.

Each retail customer shall be obligated to pay Transition Charges for its
applicable class. The Transition Charge shall be applied to all service received
by the customer during the applicable billing period. If a customer was taking
service in more than one rate class through one point of service on April
30,1999, or on the day before the customer discontinued taking service from the
Company on a frozen rate schedule, its Transition Charges shall be determined as
follows:

                  1.       For customers taking service under two or more rates
                           through a single meter, the following order will be
                           used to determine Transition Charges for the
                           customer:

                  (a)      If the customer takes service in one or more Capped
                           Classes (other than SCP) through a single meter, the
                           service shall be allocated first to Capped Classes in
                           ascending order of unit Transition Charges beginning
                           with the Capped Class with the lowest unit Transition
                           Charge. All service to the customer, up to the lesser
                           of (i) the highest hourly on-peak kW for total
                           premises load (Total kW) or the Monthly Cap for the
                           class, shall be deemed to be service under the Capped
                           Class with the lowest unit Transition Charge. If the
                           Total kW is greater than the Monthly Cap for the
                           class with lowest unit Transition Charge, the
                           difference up to the Monthly Cap for the Capped Class
                           with the next lowest unit Transition Charge will be
                           deemed to be service under the Capped Class with the
                           next lowest unit Transition Charge. The remainder
                           will then similarly be allocated to each other Capped
                           Class under which the customer is served until the
                           Total kW has been allocated or all applicable Monthly
                           Caps have been reached.

                  (b)      If the total amount allocated to Capped Classes under
                           (a) is less than the Total kW, the remainder, up to
                           the Monthly Cap for SCP shall be deemed to be service
                           provided under SCP.

                  (c)      Any amount remaining after the allocations in (a) and
                           (b) will be deemed to be service provided under the
                           Transition Charge Class (other than Capped Classes
                           and SCP) that is applicable to the customer. If the
                           customer is not otherwise taking service under any
                           Transition Charge Class (other than Capped Classes
                           and SCP) the amount remaining after the allocations
                           in (a) and (b) shall be deemed to be service under
                           LOS-A, if the customer is served at transmission
                           voltage, or under LGS, if the customer is served at
                           distribution voltage.

In addition, each customer which has New On-Site Generation shall pay an amount
each month computed by multiplying the output of the on-site generation used to
serve the internal electric requirements of the customer (either kW or kVa, as
determined by the Transition Charge class for which the customer would qualify
if it were being served by the Company or an REP) by the Transition Charge in
effect for services provided to customers in that class during the month. This
amount shall be in addition to any Transition Charges applicable to energy or
demand actually delivered to the customer through the Company's or another T&D
Provider's facilities.

SECTION 8: STANDARD TRUE-UP FOR ADJUSTMENT OF TRANSITION CHARGES

Transition Charges will be adjusted annually effective on November 1st to ensure
that the expected collection of Transition Charges is adequate to pay principal
and interest on the Transition Bonds when due pursuant to the expected
amortization schedule, pay as due all other qualified costs and to fund the
overcollateralization account to the required level. In addition, in limited
circumstances the Transition Charges may be adjusted at other times but not more
frequently than once each quarter (Interim Adjustments). The Interim Adjustments
will be made if, after application of collections in accordance with the terms
of the Transition Bond indenture, the actual principal balance of bonds
outstanding at the next bond payment date will be more than 5% higher than the
expected principal balance as set out on the expected amortization schedule. All
annual and interim adjustments will be designed to cause (i) the outstanding
principal balance of the Transition Bonds to be equal to the scheduled balance
on the expected amortization schedule; (ii) the amount in the
overcollateralization subaccount to be equal to the required
overcollateralization level; (iii) the amount in the capital subaccount to be
equal to the required capital plus any investment earnings on amounts in the
capital subaccount to the extent that the investment earnings have not been
released to the SPE and (iv) the reserve subaccount to be zero by the payment
date immediately preceding the next adjustment or by the final payment date, if
the next payment date is the final payment date.

PART A: TRUE-UP ADJUSTMENT PROCEDURE FOR STANDARD AND INTERIM TRUE-UPS

Servicer will calculate the Adjusted Transition Charges using the methodology
described below and will file the Adjusted Transition Charges with the
Commission. Annual adjustments will be filed 15 days prior to the effective date
of the Adjusted Transition Charges unless an adjustment to the RAAFs is required
under Section 6 (including Intra-Group Allocation Adjustments under Part D of
Section 6) in which case the annual adjustment will be filed not later than 90
days prior to the effective date. Interim Adjustments will be filed not less
than 15 days prior to the effective date of the Adjusted Transition Charges.

The Adjusted Transition Charge for the upcoming period for each class (TCc)
shall be computed as follows:

For the residential class,

         TC(c)= PBR(T)*(RAAF(c)+RAAFA(c)+YRAAFA(c)(t))/FBU(c)

For classes in the Commercial and Industrial TC Groups:

         TC(c)= TC(c)(-1) {(SIGMA)[PBR(T) * (RAAF(c)+RAAFA(c)+YRAAFA(c)(t))] /
         (SIGMA)(TC(c)(-1)*FBU(c))} For all classes in the applicable group.

         Where

                  TC(C)(-1) = the transition charge for that class from the
                  previous period

                  (the 12 months beginning on the effective date of the adjusted
                  transition charges in the case of annual true-ups and the
                  period until the next scheduled annual true-up in the case of
                  interim adjustments). The Periodic Billing Requirement will be
                  the amounts required to pay principal and interest on the
                  Transition Bonds when due pursuant to the expected
                  amortization schedule, pay as due all other qualified costs to
                  fund the overcollateralization account to the required level
                  and to recover any net system under-collections or credit any
                  net system over-collections so that (i) the outstanding
                  principal balance of the Transition Bonds will be equal to the
                  scheduled balance on the expected amortization schedule; (ii)
                  the amount in the overcollateralization subaccount will be
                  equal to the required overcollateralization level; (iii) the
                  amount in the capital subaccount will be equal to the required
                  capital plus any investment earnings on amounts in the capital
                  subaccount to the extent that the investment earnings have not
                  been released to the SPE and (iv) the reserve subaccount will

                  RAAFA(c)= the adjustment (if any) from Section 6, Part B, Step
                  5

                  YRAAFA(c)(t)= the adjustment from Section 6, Part C, Step 5
                  for every year t in which an adjustment was made unless that
                  adjustment was discontinued under Section 6, Part C, Step 6.

SECTION 9: BILLING AND COLLECTION TERMS AND CONDITIONS

Transition Charges will be billed and collected as set forth in this Schedule
TC. The terms and conditions for each party are set forth below.

PART A: BILLING AND COLLECTION PRIOR TO CUSTOMER CHOICE

A.       Billing by Servicer to end-use customers:

         1.       Payment terms for each Transition Charge Class will be
                  identical to those which are contained in the Company's rate
                  schedules in effect on November 1, 1999 and applicable to
                  customers in that class.

         2.       Servicer shall have the same right to terminate service for
                  non-payment of Transition Charges as the Company has to
                  terminate service for non-payment of charges under the
                  Company's rate schedules. Any termination shall comply with
                  applicable Commission rules.

B.       Billings by Servicer to T or D Providers:

         1.       When former retail customers of the Company in multiply
                  certificated service areas are taking service from other T or
                  D Providers, and the customer did not request to switch to the
                  other T or D Provider prior to May 1, 1999, the Transition
                  Charges will be billed to and collected from the other T or D
                  Provider.

         2.       The T or D Provider shall pay all Transition Charges not later
                  than 16 days after the bill is mailed by Servicer. The T or D
                  Provider shall make such payment regardless of whether it
                  collects such charges from the end-use retail customer.

C.       Billings by Servicer to New On-Site Generation:

         1.       Customers subject to Transition Charges for New On-Site
                  Generation shall pay such charges in full not later than
                  sixteen days after the date the bill is mailed to the
                  customer.

         2.       Transition Charges applicable to New On-Site Generation are in
                  addition to applicable Transition Charges under A above.

         3.       If the entity with New On-Site Generation receives
                  transmission or distribution service from the Company or
                  another T or D Provider, Servicer shall have the same right to
                  terminate service or to require the other provider to
                  terminate service for non-payment of Transition Charges as the
                  Company has to terminate

PART B: BILLING AND COLLECTION SUBSEQUENT TO CUSTOMER CHOICE.

A.       Billings by Servicer to other T or D Providers:

         1.       Transition Charges applicable to former retail customers of
                  the Company in multiply certificated service areas who are now
                  taking service from other T or D Providers will be billed to
                  and collected from the other T or D Provider, which, in turn
                  will be responsible for collecting the Transition Charges from
                  the retail customers.

         2.       The T or D Provider shall pay all Transition Charges not later
                  than 35 days after bill is mailed by Servicer. The T or D
                  Provider shall make such payment regardless of whether it
                  collects such charges from the end-use retail customer.

B.       Billings by Servicer to New On-Site Generation:
                                                        -

                  addition to applicable transition charges under A above or C
                  below.

         3.       If the entity with New On-Site Generation receives
                  transmission or distribution service from the Company or
                  another T or D Provider, Servicer shall have the same right to
                  terminate service or require the other provider to terminate
                  service for non-payment of Transition Charges as the Company
                  has to terminate service for non-payment of charges under the
                  Company's rate schedules. Any termination shall comply with
                  applicable Commission rules.

C.       Billings by the REP or its replacement to end-use customers:

                  collected, all Transition Charges applicable to consumption by
                  retail customers served by the REP.

         2.       If the Servicer is providing the metering, metering data will
                  be provided to the REP at the same time as the billing. If the
                  Servicer is not providing the metering, the entity providing
                  metering services will be responsible for complying with
                  Commission rules and ensuring that the Servicer and the REP
                  will receive timely and accurate metering data in order for
                  the Servicer to meet its obligations under

                  to billing and true-ups.

         3.       Each REP must (1) have a long-term, unsecured credit rating of
                  not less than "BBB-" and "Baa3" (or the equivalent) from
                  Standard & Poor's and Moody's Investors Service, respectively,
                  or (2) provide (A) a deposit of two months' maximum expected
                  Transition Charge collections in the form of cash, (B) an
                  affiliate guarantee, surety bond, or letter of credit
                  providing for payment of such amount of Transition Charge
                  collections in the event that the REP defaults in its payment
                  obligations, or (C) a combination of any of the foregoing. A
                  REP that does not have or maintain the requisite long-term,
                  unsecured credit rating may select which alternate form of
                  deposit, credit support, or combination thereof it will
                  utilize, in its sole discretion. The Indenture Trustee shall
                  be the beneficiary of any affiliate guarantee, surety bond or
                  letter of credit. The provider of any affiliate guarantee,
                  surety bond, or letter of credit must have and maintain a
                  long-term, unsecured credit ratings of not less than "BBB-"
                  and "Baa3" (or the equivalent) from Standard & Poor's and
                  Moody's Investors Service, respectively.

         4.       If the long-term, unsecured credit rating from either Standard
                  & Poor's or Moody's Investors Service of a REP that did not
                  previously provide the alternate form of deposit, credit
                  support, or combination thereof or of any provider of an
                  affiliate guarantee, surety bond, or letter of credit is
                  suspended, withdrawn, or downgraded below "BBB-" or "Baa3" (or
                  the equivalent), the REP must provide the alternate form of
                  deposit, credit support, or combination thereof, or new forms
                  thereof, in each case from providers with the requisite
                  ratings, within 10 business days following such suspension,
                  withdrawal, or downgrade. A REP failing to make such provision
                  must comply with the provisions set forth in paragraph 3 of
                  Section D, Billings by Servicer to the REP or its replacement
                  (when applicable).

         5.       The computation of the size of a required deposit shall be
                  agreed upon by the Servicer and the REP, and reviewed during
                  no more frequently than quarterly to ensure that the deposit
                  accurately reflects two months' maximum collections. Within 10
                  business days following such review, (1) the REP shall remit
                  to the Indenture Trustee the amount of any shortfall in such
                  required deposit or (2) the Servicer shall instruct the
                  Indenture Trustee to remit to the REP any amount in excess of
                  such required deposit. A REP failing to so remit any such
                  shortfall must comply with the provisions set forth in
                  Paragraph 3 of the Section D, Billings by Servicer to the REP
                  or its replacement (when applicable). REP cash deposits shall
                  be held by the Indenture Trustee, maintained in a segregated
                  account, and invested in short-term high quality investments,
                  as permitted by the rating agencies rating the Transition
                  Bonds. Investment earnings on REP cash deposits shall be
                  considered part of such cash deposits so long as they remain
                  on deposit with the Indenture Trustee. At the instruction of
                  the Servicer, cash deposits will

                  be remitted with investment earnings to the REP at the end of
                  the term of the Transition Bonds unless otherwise utilized for
                  the payment of the REP's obligations for Transition Bond
                  payments. Once the deposit is no longer required, the Servicer
                  shall promptly (but not later than 30 calendar days) instruct
                  the Indenture Trustee to remit the amounts in the segregated
                  accounts to the REP.

         6.       In the event that a REP or the Provider of Last Resort (POLR)
                  is billing customers for Transition Charges, the REP shall
                  have the right to transfer the customers to the POLR (or to
                  another certified REP) or to direct the servicer to terminate
                  transmission and distribution service to the end-use customer
                  for non-payment by the end-use customer pursuant to applicable
                  Commission rules.

D.       Billings by the Servicer to the REP or its replacement (when
         applicable):

         1.      Servicer will bill and collect from REPs all Transition Charges
                 applicable to consumption by retail customers served by the
                 REP, including applicable former customers and New On-Site
                 Generation.

         2.       Payments of Transition Charges are due 35 calendar days
                  following each billing by the Servicer to the REP, without
                  regard to whether or when the REP receives payment from the
                  end-use retail customers. The Servicer shall accept payment by
                  electronic funds transfer, wire transfer, and/or check.
                  Payment will be considered received the date the electronic
                  funds transfer or wire transfer is received by the Servicer,
                  or the date the check clears. A 5% penalty is to be charged on
                  amounts received after 35 calendar days; however, a 10
                  calendar-day grace period will be allowed before the REP is
                  considered to be in default. A REP in default must comply with
                  the provisions set forth in paragraph 3 of this Section D. The
                  5% penalty will be a one-time assessment measured against the
                  current amount overdue from the REP to Servicer. The "current
                  amount" consists of the total unpaid Transition Charges
                  existing on the 36th calendar day after billing by the
                  Servicer. Any and all such penalty payments will be made to
                  the Indenture Trustee to be applied against Transition Charge
                  obligations. A REP shall not be obligated to pay the overdue
                  Transition Charges of another REP. If a REP agrees to assume
                  the responsibility for the payment of overdue Transition
                  Charges as a condition of receiving the customers of another
                  REP that has decided to terminate service to those customers
                  for any reason, the new REP shall not be assessed the 5%
                  penalty upon such Transition Charges; however, the prior REP
                  shall not be relieved of the previously-assessed penalties.

         3.       After the 10 calendar-day grace period (the 45th calendar day
                  after the billing date), the Servicer shall have the option to
                  seek recourse against any cash deposit, affiliate guarantee,
                  surety bond, letter of credit, or combination thereof provided
                  by the REP, and avail itself of such legal remedies as may be
                  appropriate to collect any remaining unpaid Transition Charges
                  and associated penalties due Servicer after the application of
                  the REP's deposit or alternate form of credit support. In
                  addition, a REP that is in default with respect to the
                  requirements set forth in paragraphs 4 and 5 of Section C and
                  paragraph 2 of this Section D shall select and implement one
                  of the following options:

                  (a)      Allow the POLR or a qualified REP of the customer's
                           choosing to immediately assume the responsibility for
                           the billing and collection of Transition Charges.

                  (b)      Immediately implement other mutually suitable and
                           agreeable arrangements with Servicer. It is expressly
                           understood that the Servicer's ability to agree to
                           any other arrangements will be limited by the terms
                           of the servicing agreement and requirements of rating
                           agencies that have rated the bonds necessary to avoid
                           suspension, withdrawal or downgrade of the ratings on
                           the Transition Bonds.

                  (c)      Arrange that all amounts owed by retail customers for
                           services rendered be timely billed and immediately
                           paid directly into a lock-box controlled by Servicer
                           with such amounts to be applied first to pay
                           Transition Charges before the remaining amounts are
                           released to the REP. All costs associated with this
                           mechanism will be borne solely by the REP.

                  If a REP that is in default does not immediately select and
                  implement one of the options specified in (a), (b) or (c) or,
                  after so selecting one of the foregoing options, fails to
                  adequately meet its responsibilities thereunder, then the
                  Servicer shall immediately implement option (a). Upon
                  re-establishment of compliance with the requirements set forth
                  in paragraphs 4 and 5 of Section C and paragraph 2 of this
                  Section D and the payment of all past-due amounts and
                  associated penalties, the REP will no longer be required to
                  comply with this paragraph 3.

         4.       The initial POLR appointed by the Commission, or any
                  Commission-appointed successor to the POLR, must meet the
                  minimum credit rating or deposit/credit support requirements
                  described in paragraph 3 of Section C ("Billings by the REP or
                  its Replacement to end-use customers")in addition to any other
                  standards that may be adopted by the Commission. If the POLR
                  defaults or is not eligible to provide such services,
                  responsibility for billing and collection of Transition
                  Charges will immediately be transferred to and assumed by the
                  Servicer until a new POLR can be named by the Commission or
                  the customer requests the

                  services of a certified REP. Retail customers may never be
                  re-billed by the successor REP, the POLR, or the Servicer for
                  any amount of Transition Charges they have paid their REP
                  (although future Transition Charges shall reflect REP and
                  other system-wide charge-offs). Additionally, if the amount of
                  the penalty detailed in paragraph 2 of this Section D is the
                  sole remaining past-due amount after the 45th calendar day,
                  the REP shall not be required to comply with clauses (a), (b)
                  or (c) of paragraph 3 of this Section D, unless the penalty is
                  not paid within an additional 30 calendar days.

         5.       In the event that the Servicer is billing customers for
                  Transition Charges, the Servicer shall have the right to
                  terminate transmission and distribution service to the end-use
                  customer for non-payment by the end use customer pursuant to
                  applicable Commission rules.

         6.       The REP will be allowed to hold back an allowance for
                  charge-offs in its payments to the Servicer. Such charge-off
                  rate will be recalculated each year in connection with the
                  annual true-up procedure. In the initial year, REPs will be
                  allowed to remit payments based on the same system-wide
                  charge-off percentage then being used by the Servicer to remit
                  payments to the indenture trustee for the holders of
                  Transition Bonds. On an annual basis in connection with the
                  true-up adjustment process, the REP and the Servicer will be
                  responsible for reconciling the amounts held back with amounts
                  actually written off as uncollectable in accordance with the
                  terms agreed to by the REP and the Servicer, provided that:

                  (a)      The REP's right to reconciliation for write-offs will
                           be limited to customers whose service has been
                           permanently terminated and whose entire accounts
                           (i.e., all amounts due the REP for its own account as
                           well as the portion representing Transition Charges)
                           have been written off.

                  (b)      The REP's recourse will be limited to a credit
                           against future Transition Charge payments unless the
                           REP and the Servicer agree to alternative
                           arrangements, but in no event will the REP have
                           recourse to the Indenture Trustee, the SPE or the
                           SPE's funds for such payments.

                  (c)      The REP shall provide information on a timely basis
                           to the Servicer so that the Servicer can include the
                           REP's default experience and any subsequent credits
                           into its calculation of the adjusted Transition
                           Charge rates for the next transition charge billing
                           period and the REP's rights to credits will not take
                           effect until after such adjusted Transition Charge
                           rates have been implemented.

         7.       In the event that a REP disputes any amount of billed
                  Transition Charges, the REP shall pay the disputed amount
                  under protest according to the timelines detailed in paragraph
                  2 of this Section D. The REP and the Servicer shall first

                  attempt to informally resolve the dispute, but if they fail to
                  do so within 30 calendar days, either party may file a
                  complaint with the Commission. If the REP is successful in the
                  dispute process (informal or formal), the REP shall be
                  entitled to interest on the disputed amount paid to the
                  Servicer at the Commission-approved interest rate. Disputes
                  about the date of receipt of Transition Charge payments (and
                  penalties arising thereof) or the size of a required REP
                  deposit will be handled in a like manner. It is expressly
                  intended that any interest paid by the Servicer on disputed
                  amounts shall not be recovered through Transition Charges if
                  it is determined that the Servicer's claim to the funds is
                  clearly unfounded. No interest shall be paid by the Servicer
                  if it is determined that the Servicer has received inaccurate
                  metering data from another entity providing competitive
                  metering services pursuant to Utilities Code Section 39.107.

         8.       If the Servicer is providing the metering, metering data will
                  be provided to the REP at the same time as the billing. If the
                  Servicer is not providing the metering, the entity providing
                  metering services will be responsible for complying with
                  Commission rules and ensuring that the Servicer and the REP
                  will receive timely and accurate metering data in order for
                  the Servicer to meet its obligations under the Servicing
                  Agreement and the Financing Order with respect to billing and
                  true-ups.

                           OTHER TERMS AND CONDITIONS

If the customer or REP pays only a portion of its bill, a pro-rata portion of
Transition Charge revenues shall be deemed to be collected. The Company will
allocate any shortfall first, ratably based on the amount owed for Transition
Charges and the amount owed for other fees and charges, other than late charges,
owed to the Company or any successor, and second, all late charges shall be
allocated to the Company or any successor.

If the Company does not regularly include the notice described below in the
bills sent by it to REPs or directly to retail customers, then at least once
each year the Company shall cause to be prepared and delivered to REPs and such
customers a notice stating, in effect, that the amount billed includes
Transition Charges which were authorized by the Financing Order dated May 31,
2000 and have been transferred to and are being collected on behalf of
CenterPoint Energy Transition Bond Company, LLC and are not owned by the
Company. In the customer's initial bill from the REP and at least once each year
thereafter, each REP that bills Transition Charges shall cause to be prepared
and delivered to its customers a notice stating, in effect, that the amount
billed includes Transition Charges which were authorized by the Financing Order
dated May 31, 2000 and have been transferred to and are being collected on
behalf of CenterPoint Energy Transition Bond Company, LLC and are not owned by
the REP or the Company, and that under certain circumstances described in
Schedule TC Servicer may be permitted to collect the Transition Charges directly
from the retail customer. Such notice shall be included either as an insert to
or in the text of the bills delivered to such REPS or customers, as applicable,
or shall be

         under certain circumstances described in Schedule TC Servicer may be
         permitted to collect the Transition Charges directly from the retail
         customer. Such notice shall be included either as an insert to or in
         the text of the bills delivered to such REPS or customers, as
         applicable, or shall be delivered to customers by electronic means or
         such other means as Servicer or the REP may from time to time use to

                           Forecast of Electric Usage

In support of CenterPoint Energy Houston Electric, LLC's annual filing to update
its Transition Charges, forecasts of electric usage (kWh, kVA and kW billing
determinants as applicable) were prepared for the various TC classes. These
classes reflect the "bundled" rate classes which were in effect prior to
implementation of retail choice in 2002. The Transition Charge classes are
defined by Section 4 of the "Schedule TC-Transition Charges" in CenterPoint
Energy's "Tariff for Retail Delivery Service". In many cases, the customer
make-up of the Transition Charge classes differ from the rate classes applicable
to energy delivery under "unbundled" rates today. The forecast is for the period
from November 2003 through October 2004.

DEMOGRAPHIC AND ECONOMIC ASSUMPTIONS

Various sources of historical and forecasted data were reviewed to help
establish appropriate assumptions for the forecast. The majority of the
historical and forecasted values of CMSA population, inflation rate and real
income are from the Perryman Group. The US macroeconomic outlook is from the
EIA. Other sources reviewed included Economy.Com for Houston PMSA and
macroeconomic outlooks, DATABook Houston (May 2003) by the Institute for
Regional Forecasting at the University of Houston, materials from the Greater
Houston Partnership and Federal Reserve Bank of Dallas

PREPARATION OF THE FORECAST

Forecasts were prepared for Transition Charge classes as follows:

A.  Distribution Voltage Classes

Residential The forecast of residential kWh sales is the product of (A) the
number of residential customers projected for each month and (B) use per
residential customer projected for each month assuming normal weather. The
forecasted number of residential customers is population driven and assumes 3.18
persons per new household. kWh usage is based upon a least squares regression
model. The model has terms (independent variables) for (1) the average numbers
of days billed, (2) heating degree hours (two terms described below), (3)
cooling degree hours (two terms described below), (4) real income per
residential customer, (5) an interaction term for cooling degree hours and
average real electric price (where the average real electric price is an
exponential average of the prior month's average electric price and the prior
month's average electric price in the previous year), (6) a dummy variable for
the month of January and (7) another dummy variable to "true up" the model to
the last 12 months of historical usage.

The residential model uses a "linear spline model" approach to estimate the kWh
response of customers to heating and cooling degree hours. The spline model
approach is

                                       55

<PAGE>

used in recognition that the kWh response to heating and cooling degree hours is
not entirely linear. There are two heating terms in the model. The first term
(HEAT1=HDH base 65 - HDH base 55) in the model estimates the response (slope) of
residential kWh per customer as temperatures drop from 65 degrees down to 55
degrees. The second term (HEAT2=HDH base 55) starts at 55 degrees and is used to
estimate the slope as temperatures get colder than 55 degrees. Similarly, there
are two cooling terms. The first cooling term (COOL1=CDH base65 - CDH base 72)
estimates the slope for temperatures ranging from 65 degrees up to 72 degrees.
The second term (COOL2 = CDH base 72) starts at 72 degrees and is used to
estimate the slope for temperatures above 72 degrees. To approximate the lagging
and dampening effects of insulation, an exponentially weighted average of
temperature is used to calculate billing month heating degree hours and cooling
degree hours which in turn are used to calculate the HEAT1, HEAT2, COOL1 and
COOL2 terms described above. The exponentially weighted average of temperature
is calculated with the current hour's actual temperature receiving a 0.25 weight
and the previous hour's exponentially weighted average temperature receiving a
0.75 weight.

MGS & LGS For the distribution portion only of the MGS & LGS classes
(alternatively referred to as MGSD and LGSD), a model of kWh per customer is
estimated for the combined MGSD/LGSD classes. A combined class approach is used
because of rate migration which has historically occurred between the two
classes. Migration was most pronounced in 1996 after the kVA minimum in the LGS
rate was lowered from 600 kVA to 400 kVA. The model has terms (independent
variables) for (1) the average numbers of days billed, (2) heating degree hours,
(3) cooling degree hours, (4) a dummy variable for the month of January to
reflect closure of many office buildings and retail stores on Christmas day and
New Years day, (5) a variable used to account for seasonal changes in metered
lighting loads, (6) a dummy variable for the 1st quarter of 2002 to offset noise
in the data due to billing problems associated with the implementation of retail
choice in January of 2002 and (7) another dummy variable to "true up" the model
to the last 12 months of historical usage. To reflect each of the billing
systems used to bill MGSD customers (CIS and BES) and LGSD customers (BES only),
the combined MGSD/LGSD forecast uses a weighted average of CIS and BES read
schedules (51% and 49%, respectively) to calculate the average numbers of days
billed and the heating and cooling degree hour terms. Multiplying the forecasted
kWh per customer by the projected number of MGSD/LGSD customers provides an
estimate of the combined MGS/LGS MWH sales.

The heating and cooling degree hour terms are the same as those described for
the residential model, except for the CIS and BES weight factors mentioned
above. The a priori expectation for the slopes, however, is much different for
the combined MGSD/LGSD class than for the residential class. Based upon
historical hourly load data, kWh usage by the MGSD class is relatively flat
between 55 and 65 degrees and the LGSD class does not hit a minimum load until
temperatures drop to approximately 55 degrees. This indicates that air
conditioning usage for the LGSD class starts at approximately 55 degrees.
Consequently, the combined MGSD/LGSD model is expected to show little response
to temperatures between 65 degrees and 55 degrees.

To determine individual forecasts of MWH sales for the MGSD and LGSD classes,
the next step was to prepare a forecast of MWH for the LGSD class in isolation.
The LGSD

model is similar to the model for the combined MGSD/LGSD classes described
above, but only uses data from November 1996 to May 2003. MWH sales for the LGSD
class is calculated as the product of the forecasted use per customer and the
projected number of LGSD customers. Next, MWH sales are forecasted for the MGSD
class by calculating the difference between the MWH forecast for the combined
MGSD/LGSD classes and the MWH forecast for the LGSD class. Historical ratios are
then used to estimate billing determinants including demand for the MGSD class
with loads above 10 kVA, demand for the LGSD class and billing kWh for the MGSD
class with loads below 10 kVA . The data is supplemented with customer
information on any capped rates.

Lighting Estimates of kWh usage for the MLS and SPL classes are based upon
recent trends in commercial (MLS and SPL) and municipal lighting (SPL),
respectively.

B. Transmission Voltage Classes

MGS & LGS The transmission portion of the MGS and LGS rates (also referred to as
MGS-T and LGS-T) represent a small portion of the transmission class and are
estimated in aggregate using a recent trend. This class aggregate is then
supplemented with customer information on any capped rates and historical ratios
pertaining to class usage.

Large Industrial Customers Individual kW and usage estimates are prepared for
many large industrial customers. These estimates reflect recent billing history,
anticipated economic conditions in customer's particular industries and whenever
possible specific information about customer's plans for the future. This data
is supplemented with customer information on capped rates and historical ratios
pertaining to class usage history.
