                       ---------------------------------

     SECTION 2.01.  Conveyance of Transition Property. In consideration of the
                    ---------------------------------
Note Issuer's delivery to or upon the order of the Seller of $22,322,405, the
Seller does hereby irrevocably sell, transfer, assign, set over and otherwise
convey to the Note Issuer, without recourse (subject to the obligations herein),
all right, title and interest of the Seller in and to the Transition Property
(such sale, transfer, assignment, set over and conveyance of the Transition
Property includes, to the fullest extent permitted by the Statute, the
assignment of all revenues, collections, claims, rights, payments, money or
proceeds of or arising from the FTA Charges pursuant to the Financing Order and

conveyance is hereby expressly stated to be a sale and, pursuant to Section
844(a) of the PU Code, shall be treated as an absolute transfer of all of the

rights in

terms, subject to applicable insolvency, reorganization, moratorium, fraudulent
transfer and other similar laws relating to or affecting creditors' rights

          obligated to repurchase the Transition Property if (A) within 90 days

          purpose, to pay all interest payments that will become due on the

          and the Seller has not taken remedial action such that there is not
          and will not be a material adverse effect on the Certificateholders as
          a result of such breach, then the Seller

                                       13
<PAGE>

          shall repurchase the Transition Property from the Note Issuer for the
          Repurchase Price on the Repurchase Date.

          (iii)  Upon the payment by the Seller of the Repurchase Price pursuant

     (a)  Safekeeping.  The Servicer shall hold the Transition Property Records
          -----------
on behalf of the Note Issuer and maintain such accurate and complete accounts,
records and computer systems pertaining to the Transition Property Records as
shall enable the Note Issuer to comply with this Agreement and the Indenture.
In performing its duties as custodian, the Servicer shall act with reasonable
care, using that degree of care and diligence that the Servicer exercises with
respect to comparable assets that the Servicer services for itself or, if
applicable, for others.  The Servicer shall promptly report to the Note Issuer
and the Note Trustee any failure on its part to hold the Transition Property
Records and maintain its accounts, records and computer systems as herein
provided and promptly take appropriate action to remedy any such failure.
Nothing herein shall be deemed to require an initial review or any periodic
review by the Note Issuer or the Note Trustee of the Transition Property
Records.  The Servicer's duties to hold the Transition Property Records on
behalf of the Note Issuer set forth in this Section 5.02, to the extent such
Transition Property Records have not been previously transferred to a successor
Servicer pursuant to Article VII, shall terminate three years after the earlier

available for inspection to the Note Issuer and the Note Trustee or their
respective duly authorized representatives, attorneys or auditors the Transition
Property Records at such times during normal business hours that the Note Issuer
or the Note Trustee shall reasonably request and that do not unreasonably
interfere with the Servicer's normal operations.  Nothing in this Section
5.02(b) shall affect the obligation of the Servicer to observe any applicable
law (including any CPUC Regulations) prohibiting disclosure of information
regarding the California Customers, and the failure of the Servicer to provide
access to such information as a result of such obligation shall not constitute a
breach of this Section 5.02(b).

     (c) Release of Documents.  Upon instruction from the Note Trustee, the
         --------------------
Servicer shall release any Transition Property Records to the Note Trustee, the

Code, the Financing Order or any Advice Letter, and the Servicer agrees to take
such legal or administrative actions, including defending against or instituting
and pursuing legal actions and appearing or testifying at hearings or similar
proceedings, as may be reasonably necessary to block or

                                       33
<PAGE>

overturn any attempts to cause a repeal of, modification of or supplement to the
Statute or the Financing Order or the rights of holders of Transition Property
by legislative enactment, voter initiative or constitutional amendment that
would be adverse to Certificateholders. The costs of any such action shall be
payable from FTA Collections as an Operating Expense in accordance with the
priorities set forth in Section 8.02(d) of the Indenture. The Servicer's
obligations pursuant to this Section 5.02 shall survive and continue
notwithstanding the fact that the payment of Operating Expenses pursuant to
Section 8.02(d) of the Indenture may be delayed (it being understood that the
Servicer may be required to advance its own funds to satisfy its obligations
hereunder).

     SECTION 5.03.  Instructions; Authority to Act.  For so long as any Notes
     ------------   ------------------------------
remain outstanding, the Servicer shall be deemed to have received proper
instructions with respect to the Transition Property Records upon its receipt of
written instructions signed by a Trust Officer of the Note Trustee.

     SECTION 5.04.  Custodian's Indemnification.  The Servicer as custodian

portion of any such amount resulting from the willful misconduct, bad faith
or gross negligence of the Note Issuer, the Trust, the Certificate Trustee, the
Delaware Trustee, the Note Trustee, the Infrastructure Bank, the STO, the
Noteholders or the Certificateholders, as the case may be.

have been terminated under Section 7.01, the appointment of such Servicer as
custodian shall be terminated by the Note Trustee or by the Holders of Notes

contemplated by this Agreement or any Basic Document, other than any Loss
incurred by reason or result of the gross negligence or willful misconduct of
the Note Trustee, the Certificate Trustee or the Delaware Trustee, as the case
may be; provided, however, that the foregoing indemnity is extended to the Note
        --------  -------
Trustee, the Certificate Trustee and the Delaware Trustee solely in their
respective capacities as trustees and not for the benefit of the Noteholders or
the Certificateholders. The obligations of the Servicer set forth herein shall
survive the termination of this Agreement or the earlier resignation or removal
of the Note Trustee under the Indenture or the Certificate Trustee or the
Delaware Trustee under the Trust Agreement.

transactions referred to in clauses (a), (b) or (c) above.

     SECTION 6.04.  Limitation on Liability of Servicer and Others.  Neither the
     ------------   ----------------------------------------------
Servicer nor any of the directors or officers or employees or agents of the
Servicer shall be liable to the Note Issuer, the Note Trustee, the
Infrastructure Bank, the Noteholders, the

                                       42
<PAGE>

Trust, the Certificate Trustee, the Delaware Trustee, the Certificateholders or
any other Person, except as provided under this Agreement, for any action taken

for errors in judgment; provided, however, that this provision shall not protect
                        --------  -------
the Servicer or any such person against any liability that would otherwise be
imposed by reason of willful misconduct, bad faith or gross negligence in the
performance of duties or by reason of reckless disregard of obligations and
duties under this Agreement. The Servicer and any director or officer or
employee or agent of the Servicer may rely in good faith on the advice of
counsel reasonably acceptable to the Note Trustee or on any document of any
kind, prima facie properly executed and submitted by any Person, respecting any
matters arising under this Agreement.

     Except as provided in this Agreement, the Servicer shall not be under any
obligation to appear in, prosecute or defend any legal action that shall not be
related to or incidental to its duties to service the Transition Property in
accordance with this Agreement and that in its opinion may involve it in any
expense or liability.

     SECTION 6.05.  Sierra Pacific Power Company Not to Resign as Servicer.
     ------------   ------------------------------------------------------
Subject to the provisions of Section 6.03, Sierra Pacific Power Company shall
not resign from the obligations and duties hereby imposed on it as Servicer
under this Agreement, except upon either (a) a determination that the
performance of its duties under this Agreement shall no longer be permissible
under applicable law or (b) satisfaction of the following: (i) the Rating Agency
Condition shall have been satisfied, (ii) the CPUC shall have approved such
resignation and (iii) notice of such resignation shall have been given to

                                       43
<PAGE>

the Infrastructure Bank. Notice of any such determination permitting the
resignation of Sierra Pacific Power Company shall be communicated to the Note
Issuer, the Note Trustee, the Certificate Trustee, the Infrastructure Bank and
Moody's at the earliest practicable time (and, if such communication is not in
writing, shall be confirmed in writing at the earliest practicable time), and
any such determination shall be evidenced by an Opinion of Counsel to such
effect delivered to the Note Issuer, the Note Trustee and the Certificate
Trustee concurrently with or promptly after such notice. No such resignation
shall become effective until a successor Servicer shall have assumed the
responsibilities and obligations of Sierra Pacific Power Company in accordance
with Section 7.02.

     SECTION 6.06.  Servicing Compensation.  (a) In consideration for its
     ------------   ----------------------
services hereunder, until the Retirement of the Notes, the Servicer shall
receive a fee (the "Servicing Fee") quarterly on each Payment Date in an amount
                    -------------
equal to (i) one-fourth of 0.25 percent of the outstanding Principal Balance
(before giving effect to payments made on such date) for so long as FTA Charges
are included as a line item on Bills otherwise sent to California Customers or
(ii) one-fourth of 1.50 percent of the outstanding Principal Balance (before
giving effect to payments made on such date) if FTA Charges are not included as
a line item on Bills otherwise sent to California Customers but, instead, are
billed separately to California Customers.  The Servicer also shall be entitled
to retain as additional compensation (i) any interest earnings on FTA Payments
received by the Servicer and invested by the Servicer pursuant to Section 6(d)
of Annex I hereto during each Collection Period prior to remittance to the
Collection Account and (ii) all late payment charges, if any, collected from
California Customers or ESPs.

                                       44
<PAGE>

     (b) The Servicing Fee set forth in Section 6.06(a) above shall be paid to
the Servicer by the Note Trustee, on each Payment Date in accordance with the
priorities set forth in Section 8.02(d) of the Indenture, by wire transfer of
immediately available funds from the Collection Account to an account designated
by the Servicer.  Any portion of the Servicing Fee not paid on such date shall
be added to the Servicing Fee payable on the subsequent Payment Date.

     (c) Except as provided in Section 5.02(d), the Servicer shall be required
to pay from its own account all expenses incurred by it in connection with its
activities hereunder (including any fees to and disbursements by accountants,
counsel, or any other Person, any taxes imposed on the Servicer and any expenses
incurred in connection with reports to Noteholders and Certificateholders) out
of the compensation retained by or paid to it pursuant to this Section 6.06, and
shall not be entitled to any extra payment or reimbursement therefor.

     SECTION 6.07.  Compliance with Applicable Law.  The Servicer covenants and
     ------------   ------------------------------
agrees, in servicing the Transition Property, to comply with all laws applicable
to, and binding upon, the Servicer and relating to such Transition Property the
noncompliance with which would have a material adverse effect on the value of
the Transition Property; provided, however, that the foregoing is not intended
                         --------  -------
to, and shall not, impose any liability on the Servicer for noncompliance with
any law that the Servicer is contesting in good faith in accordance with its
customary standards and procedures.

     SECTION 6.08.  Access to Certain Records and Information Regarding
     ------------   ---------------------------------------------------
Transition Property.  The Servicer shall provide to the Noteholders, the Note
-------------------
Trustee, the

                                       45
<PAGE>

Certificate Trustee, the Infrastructure Bank and the STO access to the
Transition Property Records in such cases where the Noteholders, the Note
Trustee, the Certificate Trustee and the Infrastructure Bank shall be required
by applicable law to be provided access to such records. Access shall be
afforded without charge, but only upon reasonable request and during normal
business hours at the respective offices of the Servicer. Nothing in this
Section shall affect the obligation of the Servicer to observe any applicable
law (including any CPUC Regulation) prohibiting disclosure of information
regarding the California Customers, and the failure of the Servicer to provide
access to such information as a result of such obligation shall not constitute a
breach of this Section.

     SECTION 6.09.  Appointments.  The Servicer may at any time appoint any
     ------------   ------------
Person to perform all or any portion of its obligations as Servicer hereunder;
provided, however, that the Rating Agency Condition shall have been satisfied in
--------  -------
connection therewith; provided further that the Servicer shall remain obligated
                      ----------------
and be liable to the Note Issuer, the Note Trustee, the Certificate Trustee and
the Noteholders for the servicing and administering of the Transition Property
in accordance with the provisions hereof without diminution of such obligation
and liability by virtue of the appointment of such Person and to the same extent
and under the same terms and conditions as if the Servicer alone were servicing
and administering the Transition Property; and provided further, however, that
                                               -------- -------
nothing herein shall preclude the execution by the Servicer of an ESP Service
Agreement with ESPs.  The fees and expenses of such Person shall be as agreed
between the Servicer and such Person from time to time, and none of the Note
Issuer, the Note Trustee, the Noteholders or any other Person shall have any
responsibility therefor or

                                       46
<PAGE>

right or claim thereto. Any such appointment shall not constitute a Servicer
resignation under Section 6.05.

     SECTION 6.10.  No Servicer Advances.  The Servicer shall not make any
     ------------   --------------------
advances of interest or principal on the Notes or the Certificates.

     SECTION 6.11.  Remittances.  (a) Subject to clause (b) below, on each
     ------------   -----------
Remittance Date, the Servicer shall cause to be made a wire transfer of
immediately available funds equal to the Aggregate Remittance Amount for the
applicable Collection Period to the General Subaccount of the Collection
Account.  Prior to each remittance to the General Subaccount of the Collection
Account pursuant to this Section, the Servicer shall provide written notice to
the Note Trustee of each such remittance (including the exact dollar amount to
be remitted).

     (b) Notwithstanding the foregoing clause (a) and subject to the succeeding
clause (c),  during any period in which there exists the occurrence and
continuance of a Servicer Default, the failure to satisfy the Rating Agency
Condition, the failure of the Servicer to maintain a short-term rating of P-1 or
a long-term rating of A-2 or better by Moody's, or if there shall exist no
letter of credit in favor of the Note Trustee which shall have satisfied the
Rating Agency Condition, the Servicer shall remit to the General Subaccount of
the Collection Account the total FTA Payments estimated to have been received by
the Servicer from or on behalf of California Customers on a given Servicer
Business Day in respect of all previously Billed FTA Charges within two Servicer
Business Days of receipt thereof by the Servicer (the "Daily Remittance").  On
                                                       ----------------
or before each Remittance Date during any period described in this clause (b),
the Servicer shall calculate the amount of

                                       47
<PAGE>

any Remittance Shortfall or Excess Remittance attributable to the prior
Collection Period and (A) if a Remittance Shortfall exists, the Servicer shall
make a supplemental remittance to the General Subaccount of the Collection
Account on such Remittance Date in the amount of such Remittance Shortfall or
(B) if an Excess Remittance exists, the Servicer shall reduce the amount of each
Daily Remittance (beginning with the Daily Remittance occurring on the
Remittance Date) by the outstanding amount of such Excess Remittance until the
balance of the Excess Remittance has been reduced to zero.

     (c) Notwithstanding the foregoing clause (b), during a period in which the
Servicer fails to maintain a short-term rating of P-1 or a long-term rating A-2
or better by Moody's, the Servicer shall have the option of remitting funds
equal to the Aggregate Remittance Amount on the Remittance Date as provided in
Section 6.11(a); provided that (i) the Note Issuer shall have established and
                 --------
shall maintain the Letter of Credit for the benefit of the Note Issuer and the
Note Trustee as provided in Section 8.07 of the Indenture and (ii) the Aggregate
Remittance Amount for any Collection Period shall not exceed the amount
available to be drawn under the Letter of Credit.  In the event that the
Aggregate Remittance Amount for any Collection Period exceeds the amount
available to be drawn under the Letter of Credit the Servicer shall be subject
to the Daily Remittance of estimated FTA Payments as provided in Section
6.11(b).

     (d) The Servicer agrees and acknowledges that it holds all FTA Payments
collected by it for the benefit of the Note Issuer and that all such amounts
will be remitted by the Servicer in accordance with this Section without any
surcharge, fee, offset, charge or other deduction except (i) as set forth in
clause (b) above or clause (e) below and (ii) for late

                                       48
<PAGE>

fees permitted by Section 6.06. The Servicer further agrees not to make any
claim to reduce its obligation to remit all FTA Payments collected by it in
accordance with this Agreement, except (i) as set forth in clause (b) above or
clause (e) below and (ii) for late fees permitted by Section 6.06.

     (e) If there is an Excess Remittance, the Servicer shall be entitled either
(i) to reduce the amount which the Servicer remits to the General Subaccount of
the Collection Account on such Remittance Date by the amount of such Excess
Remittance, the amount of such reduction becoming the property of the Servicer
or (ii) to be paid immediately from the Collection Account or any subaccount
therein the amount of such Excess Remittance, such payment becoming the property
of the Servicer.  If there is a Remittance Shortfall, the amount that the
Servicer remits to the General Subaccount of the Collection Account on such
Remittance Date will be increased by the amount of such Remittance Shortfall,
such increase coming from the Servicer's own funds.

     (f) If the Note Trustee shall not have received either (i) the Aggregate
Remittance Amount pursuant to clause (a) above by 6:00 P.M. Eastern Standard
Time on such Remittance Date or (ii) notice from the Servicer that the Note
Issuer has drawn on the Letter of Credit pursuant to clause (g), the Note
Trustee on the following Business Day shall draw on the full amount of the
Letter of Credit.

     (g) If the Servicer has not wire transferred the aggregate Remittance
Amount pursuant to clause (a) by 1:00 p.m. (Eastern Standard Time) on any
Remittance Date, the Note Issuer shall, not later than 6:00 p.m. (Eastern
Standard Time) on such Remittance

                                       49
<PAGE>

Date, draw the entire amount of the Letter of Credit and simultaneously send, by
facsimile transmission, notice of the draw to the Note Trustee and the
Infrastructure Bank.

                                    -------

     SECTION 7.01.  Servicer Default.  If any one of the following events (a
     ------------   ----------------
"Servicer Default") shall occur and be continuing:
 ----------------

     (a) any failure by the Servicer to deposit in the Collection Account on
behalf of the Note Issuer any required remittance that shall continue unremedied
for a period of three Business Days after written notice of such failure is
received by the Servicer from the Note Issuer or the Note Trustee or after
discovery of such failure by an officer of the Servicer; provided, however,
                                                                   -------
that, if the Servicer fails to deposit an Aggregate Remittance Amount on any
Remittance Date pursuant to Section 6.11, then such failure by the Note Issuer
shall be deemed to be a default by the Servicer under this Agreement; or

     (b) any failure on the part of the Servicer or the Seller, as the case may
be, duly to observe or to perform in any material respect any other covenants or
agreements of the Servicer or the Seller (as the case may be) set forth in this
Agreement (including Section 4.01) or any other Basic Document to which it is a
party, which failure shall (i) materially and adversely affect the rights of
Noteholders or Certificateholders and (ii) continue unremedied for a period of
30 days after the date on which written notice of such failure, requiring the
same to be remedied, shall have been given (A) to the Servicer or the Seller (as
the case may be) by the Note Issuer or (B) to the Servicer or the Seller (as the
case may

                                       50

be) by the Note Trustee or by the Noteholders of Notes evidencing not less than
25 percent of the Outstanding Amount of the Notes of all Series; or

     (c) any representation or warranty made by the Servicer in this Agreement
shall prove to have been incorrect when made, which has a material adverse
effect on the Note Issuer or the Certificateholders and which material adverse
effect continues unremedied for a period of 60 days after the date on which
written notice thereof, requiring the same to be remedied, shall have been
delivered to the Servicer by the Note Issuer or the Note Trustee; or

     (d) an Insolvency Event occurs with respect to the Servicer or the Seller;
then, and in each and every case, so long as the Servicer Default shall not
have been remedied, either the Note Trustee, or the Holders of Notes evidencing
not less than 25 percent of the Outstanding Amount of the Notes of all Series,
by notice then given in writing to the Servicer (and to the Note Trustee if
given by the Noteholders) (a "Termination Notice") may terminate all the rights
                              ------------------
and obligations (other than the obligations set forth in Section 6.02 hereof) of
the Servicer under this Agreement.  In addition, upon a Servicer Default

to the CPUC for sequestration and payment of revenues arising with respect to
the Transition Property: (1) the Certificateholders and the Certificate Trustee
as beneficiary of any statutory lien permitted by the PU Code; (2) the Note
Issuer or its assignees; or (3) pledgees or transferees, including transferees
under Section 844 of the PU Code, of the Transition Property.  On or after the
receipt by the Servicer of a Termination

                                       51
<PAGE>

Notice, all authority and power of the Servicer under this Agreement, whether
with respect to the Notes, the Transition Property, the FTA Charges or
otherwise, shall, without further action, pass to and be vested in such
successor Servicer as may be appointed under Section 7.02; and, without
limitation, the Note Trustee is hereby authorized and empowered to execute and
deliver, on behalf of the predecessor Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
Termination Notice, whether to complete the transfer of the Transition Property
Records and related documents, or otherwise. The predecessor Servicer shall
cooperate with the successor Servicer, the Note Issuer and the Note Trustee in
effecting the termination of the responsibilities and rights of the predecessor
Servicer under this Agreement, including the transfer to the successor Servicer
for administration by it of all cash amounts that shall at the time be held by
the predecessor Servicer for remittance, or shall thereafter be received by it
with respect to the Transition Property or the FTA Charges. All reasonable costs
and expenses (including attorneys fees and expenses) incurred in connection with
transferring the Transition Poperty Records to the successor Servicer and
amending this Agreement to reflect such succession as Servicer pursuant to this
Section shall be paid by the predecessor Servicer upon presentation of
reasonable documentation of such costs and expenses.

     SECTION 7.02.  Appointment of Successor.  (a) Upon the Servicer's receipt
     ------------   ------------------------
of a Termination Notice pursuant to Section 7.01 or the Servicer's resignation
or removal in accordance with the terms of this Agreement, the predecessor
Servicer shall continue to perform its functions as Servicer under this
Agreement, and shall be entitled to receive the

                                       52
<PAGE>

requisite portion of the Servicing Fee, until a successor Servicer shall have
assumed in writing the obligations of the Servicer hereunder as described below.
In the event of the Servicer's termination hereunder, the Note Issuer shall
appoint a successor Servicer with the Note Trustee's prior written consent
thereto (which consent shall not be unreasonably withheld), and the successor
Servicer shall accept its appointment by a written assumption in form acceptable
to the Note Issuer and the Note Trustee. If within 30 days after the delivery of
the Termination Notice, the Note Issuer shall not have obtained such a new
Servicer, the Note Trustee may petition the CPUC or a court of competent
jurisdiction to appoint a successor Servicer under this Agreement. A Person
shall qualify as a successor Servicer only if (i) such Person is permitted under
CPUC Regulations to perform the duties of the Servicer, (ii) the Rating Agency
Condition shall have been satisfied and (iii) such Person enters into a
servicing agreement with the Note Issuer having substantially the same
provisions as this Agreement.

     (b) Upon appointment, the successor Servicer shall be the successor in all
respects to the predecessor Servicer and shall be subject to all the
responsibilities, duties and liabilities arising thereafter relating thereto
placed on the predecessor Servicer and shall be entitled to the Servicing Fee
and all the rights granted to the predecessor Servicer by the terms and
provisions of this Agreement.

     SECTION 7.03.  Waiver of Past Defaults.  The Noteholders of Notes

all Series may, on behalf of all Noteholders, waive in writing any default by
the Servicer in the performance of its obligations hereunder and its
consequences, except a default in making any required

                                       53
<PAGE>

deposits to the Collection Account in accordance with this Agreement. Upon any
such waiver of a past default, such default shall cease to exist, and any
Servicer Default arising therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right consequent thereto.

     SECTION 7.04.  Notice of Servicer Default.  The Servicer shall deliver to
     ------------   --------------------------
the Note Issuer, the Note Trustee, the Certificate Trustee, the Infrastructure
Bank, the STO and Moody's, promptly after having obtained knowledge thereof, but
in no event later than five Business Days thereafter, written notice in an
Officers' Certificate of any event which with the giving of notice or lapse of
time, or both, would become a Servicer Default under Section 7.01(a) or (b).

                            Miscellaneous Provisions
                            ------------------------

     SECTION 8.01.  Amendment.  (a) This Agreement may be amended in writing by
     ------------   ---------
the Servicer and the Note Issuer with five Business Days' prior written notice
given to Moody's and the prior written consent of the Note Trustee, but without
the consent of any of the Noteholders or Certificateholders, to cure any
ambiguity, to correct or supplement any provisions in this Agreement or for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions in this Agreement or of modifying in any manner the rights of
the Noteholders or the Certificateholders; provided, however, that such action
                                           --------  -------
shall not, as evidenced by an Officer's Certificate delivered to the

                                       54
<PAGE>

Note Issuer and the Note Trustee, adversely affect in any material respect the
interests of any Noteholder or Certificateholder.

     This Agreement may also be amended in writing from time to time by the
Servicer and the Note Issuer with prior written notice given to Moody's and the
prior written consent of the Note Trustee and the prior written consent of the
Holders of Notes evidencing not less than a majority of the Outstanding Amount
of the Notes of all Series, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that no such amendment shall (a) increase
                    --------  -------
or reduce in any manner the amount of, or accelerate or delay the timing of, FTA
Collections or (b) reduce the aforesaid percentage of the Outstanding Amount of
the Notes, the Noteholders of which are required to consent to any such
amendment, without the consent of the Noteholders of all the outstanding Notes.

     Promptly after the execution of any such amendment and the requisite
consents, the Note Issuer shall furnish written notification of the substance of
such amendment to the Note Trustee and Moody's.

     It shall not be necessary for the consent of Noteholders pursuant to this
Section to approve the particular form of any proposed amendment or consent, but
it shall be sufficient if such consent shall approve the substance thereof.

     Prior to its consent to any amendment to this Agreement, the Note Trustee
shall be entitled to receive and conclusively rely upon an Opinion of Counsel
stating that such amendment is authorized or permitted by this Agreement. The
Note Trustee may, but shall

                                       55
<PAGE>

not be obligated to, enter into any such amendment which affects the Note
Trustee's own rights, duties or immunities under this Agreement or otherwise.

     (b) Notwithstanding Section 8.01(a) or anything to the contrary in this
Agreement, the Servicer and the Note Issuer may amend Annex I to this Agreement
in writing with prior written notice given to the Note Trustee and Moody's, but
without the consent of the Note Trustee, Moody's or any Noteholder or
Certificateholder, solely to address changes to the Servicer's method of
calculating FTA Payments received as a result of changes to the Servicer's
current computerized customer information system, as contemplated by Section
(e)(iii) of Annex I hereto; provided that any such amendment shall not have or
                            --------
cause a material adverse effect on the Certificateholders.

     SECTION 8.02.  Protection of Title to Trust.  (a) The Servicer shall
     ------------   ----------------------------
maintain accounts and records as to the Transition Property accurately and in
accordance with its standard accounting procedures and in sufficient detail to
permit reconciliation between FTA Payments received by the Servicer and FTA
Collections from time to time deposited in the Collection Account.

     (b) The Servicer shall permit the Note Trustee and its agents at any time
during normal business hours, upon reasonable notice to the Servicer and to the
extent it does not unreasonably interfere with the Servicer's normal operations,
to inspect, audit and make copies of and abstracts from the Servicer's records
regarding the Transition Property and the FTA Charges. Nothing in this Section
8.02(b) shall affect the obligation of the Servicer to observe any applicable
law (including any CPUC Regulation) prohibiting disclosure of information
regarding the California Customers, and the failure of the Servicer to provide

                                       56
<PAGE>

access to such information as a result of such obligation shall not constitute a
breach of this Section 8.02(b).

     SECTION 8.03.  Notices.  All demands, notices and communications upon or to
     ------------   -------
the Servicer, the Note Issuer, the Note Trustee, the Infrastructure Bank, the
STO, the Certificate Trustee or Moody's under this Agreement shall be in writing

individual FTA Charges to be included on such California Customers' Bills based

such Servicer Policies and Practices may be modified from time to time, the
Servicer shall generate and issue a Bill to each California Customer, or, in the
case of a California Customer who has elected Consolidated ESP Billing, to the
Applicable ESP, with respect to such California Customer's respective FTA Charge
once every 27 to 33 days, at the same time, with the same frequency and on the

material modification to its Servicer Policies and Practices for its own
charges, it shall notify the Note Issuer, the Note Trustee, the Certificate

Consolidated ESP Billing, the Servicer shall deliver to the Applicable ESP
itemized charges for such California Customer setting forth such California

          (iii)  The Servicer shall conform to such requirements in respect of
the format, structure and text of Bills delivered to California Customers and

<PAGE>

any other means, whether electronic or otherwise, that the Servicer may from
time to time use to present its own charges to its customers. In the case of
California Customers that have elected Consolidated ESP Billing, the Servicer
shall deliver all Bills or charges to the Applicable ESPs by such means as are
mutually agreed upon by the Servicer and the Applicable ESP and are consistent
with CPUC Regulations. The Servicer or an ESP, as applicable, shall pay from its
own funds all costs of issuance and delivery of all Bills, including but not
limited to printing and postage costs as the same may increase or decrease from
time to time.

other fee or charge relating to delinquent payments, if any, or waive, vary or
modify any terms of payment of any amounts payable by a California Customer, in
each case unless such waiver or action (A) would be in accordance with the
Servicer's customary practices or

                                       70
<PAGE>

those of any successor Servicer with respect to comparable assets that it
services for itself and for others; (B) would not materially adversely affect
the rights of the Certificateholders; and (C) would comply with applicable law;
provided, however, that notwithstanding anything in the Agreement or this Annex
I to the contrary, the Servicer is authorized to write off any Billed FTA
Revenues, in accordance with its Servicer Policies and Practices, that remain
outstanding for 180 days after issuance of a Closing Bill.

          (iii) The Servicer shall accept payment from California Customers in
respect of Billed FTA Revenues in such forms and methods and at such times and
places as it accepts for payment of its own charges.  The Servicer shall accept
payment from ESPs in respect of Billed FTA Revenues in such forms and methods
and at such times and places as the Servicer and each ESP shall mutually agree
in accordance with applicable CPUC Regulations.

     (b)  Payment Processing; Allocation; Priority of Payments.

          (i)   The Servicer shall post all payments received to California

received to each California Customer's or ESP's account in proportion to the
charges contained on the outstanding Bill to such California Customer or ESP.

          (iii) Any amounts collected by the Servicer that represent partial
payments of the total Bill to a California Customer shall be allocated as
follows (A) first to amounts owed to the Note Issuer, the Seller and the
applicable ESP, regardless of age, in

                                       71
<PAGE>

proportion to their respective percentages of the total amount of their combined
outstanding charges on such Bill, and then (B) to all other outstanding amounts
owed to parties other than the Note Issuer, the Seller and the applicable ESP.

          (iv)  The Servicer shall hold all over-payments for the benefit of the
Note Issuer and the Seller and shall apply such funds to future Bill charges in
accordance with clauses (ii) and (iii) above as such charges become due.

     (c)  Accounts; Records. The Servicer shall maintain accounts and records as
to the Transition Property accurately and in accordance with its standard
accounting procedures and in sufficient detail to permit reconciliation between
payments or recoveries with respect to the Transition Property and the amounts
from time to time remitted to the Collection Account in respect of the
Transition Property.

     (d)  Investment of FTA Payments Received. Prior to remittance on the
applicable Remittance Date, the Servicer may invest FTA Payments received at its
own risk and for its own benefit, and such investments and funds shall not be
required to be segregated from the other investments and funds of the Servicer.

     (e)  Calculation of Collections; Determination of Aggregate Remittance
Amount.

in accordance with Schedule 6, the total FTA Payments estimated to have been
received by the Servicer from or on behalf of California Customers during the
prior Collection Period in respect of all previously Billed FTA Revenues
("Estimated FTA Collections"), increased or decreased, as applicable, by (A) the
amount of any Remittance Shortfall calculated for such Remittance Date or (B)
the amount of any Excess Remittance calculated for such

                                       72
<PAGE>

Remittance Date and (C) Billed FTA Revenues not accounted for or erroneously
accounted for in prior periods (collectively, the "Aggregate Remittance
Amount").

          (ii)   At the end of each year, on or before the Annual Adjustment
Date in accordance with Section 4.01(b)(i)(1) of the Agreement, the Servicer
shall update the Variables underlying the Daily Collections Curve in Schedule 6
and shall revise such curve to reflect the updated Variables. The Servicer shall
use the revised Daily Collections Curve to update the Monthly Collections Curve.

          (iii)  The Servicer and the Note Issuer acknowledge that the Servicer
has undertaken to make certain changes to its current computerized customer
information system, which changes, when functional, would affect the Servicer's
method of calculating the FTA Payments estimated to have been received by the
Servicer during each Collection Period as set forth in Schedule 6 hereto.

     Should these changes to the computerized customer information system become
functional during the term of the Agreement, the Servicer and the Note Issuer
agree that they shall review the procedures used to calculate the FTA Payments
estimated to have been received, as set forth on Schedule 6, in light of the
capabilities of such new system and shall make such modifications and/or
substitutions to such procedures and to clause (ii) above as may be appropriate
in the interests of efficiency, accuracy, cost and/or system capabilities;

substitution that will materially adversely affect the Certificateholders.  As

on which all California Customer accounts have been converted for billing under
such new system, the

                                       73
<PAGE>

Servicer shall notify the Note Trustee, the Certificate Trustee, the
Infrastructure Bank and Moody's of the same.

          (iv)   All calculations of collections, each update of the Variables
and any changes in procedures used to calculate the FTA Payments pursuant to
this Section 6(e) shall be made in good faith and in the case of any update
pursuant to clause (ii) or any change in procedures pursuant to clause (iii) in
a manner reasonably intended to provide estimates and calculations that are at
least as accurate as those that would be provided on the Closing Date utilizing
the initial Variables and procedures.

     (f)  Remittances.

          (i)    The Note Issuer shall cause to be established the Collection
Account in the name of the Note Trustee in accordance with the Indenture.

thereof to the Servicer by the earlier of  (A) five Business Days from the
effective date of such change or (B) five Business Days prior to the next

                                 Schedule 6 to
                                   Annex I to
                              Servicing Agreement

                   CALCULATION OF AGGREGATE REMITTANCE AMOUNT

     Subject to the terms and conditions of this Agreement, the Servicer shall
calculate the Aggregate Remittance Amount to be remitted to the Collection
Account on a Remittance Date in accordance with this Schedule 6.

I.   Determination of Monthly Collections Curves
     -------------------------------------------

     The following model shall be used to determine the Monthly Collections
Curves for California Residential Customers and California Small Commercial
Customers for each Collection Period.  Such Monthly Collections Curves shall be
used in the Estimation Template described in Section II of this Schedule 6.

     Assumptions
     -----------
     1.   California Customer billing is conducted on a daily basis, and each
month contains 30 days.

     2.   The Monthly Collections Curve has not varied materially over the
course of the year.

     3.   The Monthly Collections Curve is composed of a summation of historical
daily collections receipts curves ("Daily Collections Curves").
                                    ------------------------

     4.   The historical daily collections receipts curve was derived from
California Customer accounts spanning from January 1997 to December 1998.

     5.   The California Customer accounts in 1998 include 38,087 residential
accounts (representing approximately 95% of all California Residential Customer

                                       75
<PAGE>

accounts) and 4,532 small commercial accounts (representing approximately 100%
of all California Small Commercial Customer accounts.)

     6.   The California Customer accounts in 1997 include 37,758 residential
accounts (representing approximately 95% of all California Residential Customer
accounts) and 4,633 small commercial accounts (representing approximately 100%
of all California Small Commercial Customer accounts.

     7.   Each billing month has an estimated collection percentage as shown
below:
                        Estimated Collection Percentages
                        --------------------------------

                       California Residential       California Small
                       ----------------------       ----------------
      Billing Month           Customers           Commercial Customers
      -------------           ---------           --------------------

                                 72%                      28%

Methodology
-----------

     Daily Collections Curves.  In order to determine the Monthly Collections
     ------------------------
Curves, the Servicer must first determine the Daily Collections Curves.  To
derive the Daily Collections Curves, the Servicer  recorded the number of days
between when a particular bill was generated and when full payment was received.
A tally was developed to record each payment experience for the sample.
California Residential Customer accounts and California Small Commercial
Customer accounts were tallied separately.  Once the tallies were complete, the
Servicer expressed each day's tally sum as a percentage of the total number of
bills generated in the sample (i.e., 72% for California Residential Customers
and 28% for California Small Commercial Customers).

                                       76
<PAGE>

     Monthly Collections Curves.  To derive the Monthly Collections Curves, the
     --------------------------
Servicer assumed that the daily collection payment pattern was the same for
bills sent on each day of the month and that the billed amounts for a given
month are spread evenly over each day of the month.  Thus, the daily payments
received as a percent of the monthly billed can be determined for each day's
billing.  Each daily percentage shown in Attachments A and B, was multiplied by
1/30 to simulate one day's worth of collections.  Then, the Servicer took the
cumulative sum for each day (Day 1, Day 1 + Day 2, Day 1 + Day 2 + Day 3, etc.)
to produce the Monthly Collections curves shown in Attachment A to this Schedule
6.

II.  Estimation Template for Calculation of Estimated FTA Collections
     ----------------------------------------------------------------

     The Servicer shall use the Estimation Template described below to calculate
the FTA Payments estimated to have been received during the Collection Period
relating to each Remittance Date (prior to any adjustment for any Remittance
Shortfall, any Excess Remittance or any FTA Revenues not accounted for in prior
periods) (the "Estimated FTA Collections").  The Servicer shall calculate the
               -------------------------
Estimated FTA Collections separately for California Residential Customers and
California Small Commercial Customers.  In such calculations, the Servicer shall
use the Monthly Collections Curves described in Section I of this Schedule 6 in
the Estimation Template.

Where:
      M      = [a calendar month]
      n      = [the calendar month immediately prior to the Remittance Date]
               M\\(n)\\ =  the Collection Period [for which Estimated
               Collections are calculated and remitted on the Remittance Date,
               as well as the Current Billing Period with respect to such
               Remittance Date]
               A        =  percentage collected of the total Billed FTA Revenues
               billed during the Current Billing Period

                                       77
<PAGE>

               B  = percentage collected of the total Billed FTA Revenues billed
                    during the Billing Period prior to the Current Billing
                    Period

               C  = percentage collected of the total Billed FTA Revenues billed
                    during the Billing Period two periods prior to the Current
                    Billing Period

               D  = percentage collected of the total Billed FTA Revenues billed
                    during the Billing Period three periods prior to the Current
                    Billing Period

               E  = percentage collected of the total Billed FTA Revenues billed
                    during the Billing Period four periods prior to the Current
                    Billing Period

               F  = percentage collected of the total Billed FTA Revenues billed
                    during the Billing Period five periods prior to the Current
                    Billing Period

               R  = Billed FTA Revenues for a Billing Period

               S  = Estimated FTA Collections for the Collection Period
Then:

     For the Collection Period, Estimated FTA Collections (prior to any
     adjustments) equal (S) as shown in the Estimation Template below.  For each
     Collection Period, (S) is calculated separately for California Residential
     Customers and California Small Commercial Customers.

-------------------------------------------------------------------------------

Notes:
/1/ The Billed FTA Revenues (R) for multiple prior Billing Periods will be zero
    during the phase-in of the FTA Charges following the FTA Effective Date.
    Similarly, the Billed FTA Revenues for multiple succeeding Billing Periods
    will be zero during the phase-out of the FTA Charges following the FTA
    Termination Date.

/2/ The Collection Percent (A, B, C, D, E, or F) is the collection percent in
    effect at the time the FTA Charges were billed based on the Monthly
    Collections Curve then in effect.

III.   Calculation of the Aggregate Remittance Amount
       ----------------------------------------------

       The Servicer shall use the Estimated FTA Collections calculated for
California Residential Customers and California Small Commercial Customers under
Estimation Template described in Section II of this Schedule 6 to calculate the
Aggregate Remittance Amount for the Collection Period.  Subject to the terms and
provisions of this Agreement, the Servicer shall determine the Aggregate
Remittance Amount (Z) to be remitted on a Remittance Date as follows:

Where:
        M\\(n+1)\\  =  a calendar month containing a Remittance Date
        M\\(n)\\    =  a Collection Period
        S\\(r)(n)\\ =  Estimated FTA Collections for California Residential
                       Customers during a Collection Period
        S\\(s)(n)\\ =  Estimated FTA Collections for California Small Commercial
                       Customers during a Collection Period
        X\\(r)\\    =  Remittance Shortfall (Excess Remittance) for California
                       Residential Customers for a Remittance Date, if any
        X\\(s)\\    =  Remittance Shortfall (Excess Remittance) for California
                       Small Commercial Customers for a Remittance Date, if any
        Y\\(n)\\    =  Billed FTA Revenues not accounted for or erroneously
                       accounted for in prior periods, if any
        Z\\(n+1)\\  =  Aggregate Remittance Amount to be remitted on a
                       Remittance Date

Then:
     the Aggregate Remittance Amount to be remitted on the Remittance Date
     (Z\\(n+1)\\) shall be determined as follows:

 Z\\(n+1)\\  =  S\\(r)(n)\\  + S\\(s)(n)\\  +  X\\(r)\\ + X\\(s)\\  + Y\\(n)\\
