ITEM 1. Business.

                                    GENERAL

Corporate Structure and Business

   PG&E Corporation is an energy-based holding company headquartered in San
Francisco, California. Effective January 1, 1997, Pacific Gas and Electric
Company (sometimes referred to herein as the "Utility") and its subsidiaries
became subsidiaries of PG&E Corporation, which was incorporated in 1995.
Pacific Gas and Electric Company, incorporated in California in 1905, is an
operating public utility engaged principally in the business of providing
electricity and natural gas distribution and transmission services throughout
most of Northern and Central California. The Utility is primarily regulated by
the California Public Utilities Commission (CPUC) and the Federal Energy
Regulatory Commission (FERC). In the holding company reorganization, Pacific
Gas and Electric Company's outstanding common stock was converted on a share-
for-share basis into PG&E Corporation common stock. Pacific Gas and Electric
Company's debt securities and preferred stock were unaffected and remain
securities of Pacific Gas and Electric Company.

   The consolidated financial statements of PG&E Corporation incorporated
herein include the accounts of PG&E Corporation and its wholly owned and
controlled subsidiaries (collectively, PG&E Corporation). The consolidated
financial statements of Pacific Gas and Electric Company incorporated herein

   PG&E Corporation has identified four reportable operating segments. The
Utility is one reportable operating segment and the other three are part of
PG&E Corporation's National Energy Group (PG&E Gen, PG&E GT, and PG&E ET).
Financial information about each reportable operating segment is provided in
"Management's Discussion and Analysis" in the 1999 Annual Report to
Shareholders and in Note 17 of the "Notes to Consolidated Financial
Statements" beginning on page 63 of PG&E Corporation's 1999 Annual Report to
Shareholders, portions of which are filed as Exhibit 13 to this report.

   The following report includes forward-looking statements about the future
that involve a number of risks and uncertainties. These statements are based
on assumptions which management believes are reasonable and on information
currently available to management. These forward-looking statements are
identified by words such as "estimates," "expects," "anticipates," "plans,"
"believes," and other similar expressions. Actual results could differ
materially from those contemplated by the forward-looking statements. Although
PG&E Corporation and the Utility are not able to predict all the factors that
may affect future results, some of the factors that could cause future results
to differ materially from those expressed or implied by the forward-looking
statements include: the pace and extent of the ongoing restructuring of the
electric and natural gas industries across the United States; operational
changes related to industry restructuring, including changes to the Utility's
business processes and systems; the method and timing of disposition and
valuation of the Utility's hydroelectric generation assets; the timing of the
completion of the Utility's transition cost recovery and the consequent end of
the current electric rate freeze in California; any changes in the amount the
Utility is allowed to collect (recover) from its customers for certain costs
which prove to be uneconomic under the new competitive market (called
transition costs); future operating performance at the Utility's Diablo Canyon
Nuclear Power Plant (Diablo Canyon); the method adopted by the CPUC for
sharing the net benefits of operating Diablo Canyon with ratepayers and the
timing of the implementation of the adopted method; the extent of anticipated
growth of transmission and distribution services in the Utility's service
territory; future market prices for electricity; future fuel prices; the
success of management's strategies to maximize shareholder value in PG&E
Corporation's National Energy Group which may include acquisitions or
dispositions of assets or internal restructuring; the extent to which current
or planned generation development projects are completed and the pace and cost
of such completion; generating capacity expansion and retirements by others;
the successful integration and performance of acquired assets; the outcome of
the Utility's various regulatory proceedings, including the the proposal to
auction the Utility's hydroelectric generation assets, the electric
transmission rate case applications, and post-transition period ratemaking
proceedings; fluctuations in commodity gas, natural gas liquid, and
electricity prices and the ability to successfully manage such price
fluctuations; and the pace and extent of competition in the California
generation market and its impact on the Utility's costs and resulting
collection of transition costs. As the ultimate impact of these and other
factors is uncertain, these and other factors may cause future results to
differ materially from results or outcomes currently expected or sought by
PG&E Corporation.

Competition and the Changing Regulatory Environment

   The electric and gas industries are continuing to undergo significant
change. Under traditional regulation, utilities were provided the opportunity
to earn a fair return on their invested capital in exchange for a commitment
to serve all customers within a designated service territory. The objective of
this regulatory policy was to provide universal access to safe and reliable
utility services. Regulation was designed in part to take the place of
competition and ensure that these services were provided at fair prices.

   In 1998, California became one of the first states in the country to
implement electric industry restructuring and establish a competitive market
framework for electric generation. Today, most Californians may continue to
purchase their electricity from investor-owned utilities (such as Pacific Gas
and Electric Company) or they may choose to purchase electricity from
alternative generation providers (such as unregulated power generators and
unregulated retail electricity suppliers such as marketers, brokers, and
aggregators). For those customers who have not chosen an alternative
generation provider, investor-owned utilities, such as Pacific Gas and
Electric Company, continue to be the generation providers. Investor-owned
utilities continue to provide distribution services to substantially all
customers within their service territories, including those customers who
choose an alternative generation provider. The framework for electric industry
restructuring was established in Assembly

                                       2
<PAGE>

Bill 1890 (AB 1890) passed by the California Legislature and signed by the
Governor in 1996. For information about California electric industry
restructuring, see "Utility Operations--Electric Utility Operations--
California Electric Industry Restructuring" below.

   Although the initial stages of restructuring have focussed on competition
among suppliers of generation, the CPUC also is studying the effect of
distributed generation (where the electric energy source is located in close
proximity to electric demand) in the California generation market and possible
changes in the electric distribution function of traditional utilities. See
"Utility Operations--Electric Utility Operations--California Electric Industry
Restructuring--Distributed Generation and Electric Distribution Competition"
below.

   Restructuring of the natural gas industry on both the national and the
state level has given choices to California utility customers to meet their
gas supply needs. In August 1997, the CPUC approved the Gas Accord settlement
agreement (Gas Accord) which restructured the Utility's gas services and its
role in the gas market. Among other matters, the Gas Accord separated, or
"unbundled," the rates for the Utility's gas transmission services from its
distribution services. As a result, the Utility's customers may buy gas
directly from competing suppliers and purchase transmission-only and
distribution-only services from the Utility. Most of the Utility's industrial
and larger commercial customers (noncore customers) now purchase their gas
from marketers and brokers. Substantially all residential and smaller
commercial customers (core customers) buy gas as well as transmission and
distribution services from the Utility as a bundled service. For more
information about the Gas Accord and regulatory changes affecting the
California natural gas industry, see "Utility Operations--Gas Utility
Operations--Gas Regulatory Framework " below.

   Additional information concerning competition and the changing regulatory
environment is provided in "Management's Discussion and Analysis" in the 1999
Annual Report to Shareholders, beginning on page 5, and in Note 2 of the
"Notes to Consolidated Financial Statements" beginning on page 40 of the 1999
Annual Report to Shareholders, which information is hereby incorporated by
reference.

Regulation of PG&E Corporation

   PG&E Corporation and its subsidiaries are exempt from all provisions,
except Section 9(a)(2), of the Public Utility Holding Company Act of 1935
(Holding Company Act). At present, PG&E Corporation has no expectation of
becoming a registered holding company under the Holding Company Act.

   PG&E Corporation is not a public utility under the laws of California and
is not subject to regulation as such by the CPUC. However, the CPUC approval
authorizing Pacific Gas and Electric Company to form a holding company was
granted subject to various conditions related to finance, human resources,
records and bookkeeping, and the transfer of customer information. The
financial conditions provide that the Utility is precluded from guaranteeing
any obligations of PG&E Corporation without prior written consent from the
CPUC, the Utility's dividend policy shall continue to be established by the
Utility's Board of Directors as though Pacific Gas and Electric Company were a
stand-alone utility company, and the capital requirements of the Utility, as
determined to be necessary to meet the Utility's service obligations, shall be
given first priority by the Boards of Directors of PG&E Corporation and
Pacific Gas and Electric Company. The conditions also provide that the Utility
shall maintain on average its CPUC-authorized utility capital structure,
although it shall have an opportunity to request a waiver of this condition if
an adverse financial event reduces the Utility's equity ratio by 1% or more.

   The CPUC also has adopted complex and detailed rules governing transactions
between California's natural gas local distribution and electric utility
companies and their non-regulated affiliates. The rules permit non-regulated
affiliates of regulated utilities (such as PG&E Energy Services, the non-
regulated energy marketing subsidiary of PG&E Corporation) to compete in the
affiliated utility's service territory, and also to use the name and logo of
their affiliated utility, provided that in California the affiliate includes
certain designated disclaimer language which emphasizes the separateness of
the entities and that the affiliate is not regulated by the CPUC. The rules
also address the separation of regulated utilities and their non-regulated
affiliates and information

                                       3
<PAGE>

exchange among the affiliates. The rules prohibit the utilities from engaging
in certain practices, which would discriminate against energy service
providers that compete with the utility's non-regulated affiliates.

   The CPUC has also established specific penalties and enforcement procedures
for affiliate rules violations. Utilities are required to self-report
affiliate rules violations.

Regulation of Pacific Gas and Electric Company

   State Regulation

   The CPUC has jurisdiction to regulate the following utility functions
within California: electric distribution service, gas distribution service,
and gas transmission service. The CPUC regulates Pacific Gas and Electric
Company's rates and conditions of service, sales of securities, dispositions
of utility property, rates of return, rates of depreciation, and long-term
resource procurement. The CPUC also conducts various reviews of utility
performance and conducts investigations into various matters, such as
deregulation, competition, and the environment, in order to determine its
future policies. The CPUC consists of five members appointed by the Governor
and confirmed by the State Senate for six-year terms.

   The California Energy Commission (CEC) has the responsibility to make
electric-demand forecasts for the state and for specific service territories.
Based upon these forecasts, the CEC determines the need for additional energy
sources and for conservation programs. The CEC sponsors alternative-energy
research and development projects, promotes energy conservation programs, and
maintains a statewide plan of action in case of energy shortages. In addition,
the CEC certifies power plant sites and related facilities within California.
The CEC also administers funding for public purpose research and development,
and renewable technologies programs.

   Federal Regulation

   The FERC regulates electric transmission rates and access, operation of the
California Independent System Operator (ISO) and the California Power Exchange
(PX), uniform systems of accounts, and electric contracts involving sales of
electricity for resale. The FERC also has jurisdiction over the Utility's
electric transmission revenue requirements and rates. The FERC also regulates
the interstate transportation of natural gas. Further, most of the Utility's
hydroelectric facilities are subject to licenses issued by the FERC.

   The Nuclear Regulatory Commission (NRC) oversees the licensing,
construction, operation, and decommissioning of nuclear facilities, including
Diablo Canyon and the nuclear generating unit at Humboldt Bay Power Plant
(Unit 3). NRC regulations require extensive monitoring and review of the
safety, radiological, and environmental aspects of these facilities.

   Licenses and Permits

   Pacific Gas and Electric Company obtains a number of permits,
authorizations, and licenses in connection with the construction and operation
of its generating plants, transmission lines, and gas compressor station
facilities. Discharge permits, various Air Pollution Control District permits,
United States Department of Agriculture--Forest Service permits, FERC
hydroelectric facility and transmission line licenses, and NRC licenses are
the most significant examples. Some licenses and permits may be revoked or
modified by the granting agency if facts develop or events occur that differ
significantly from the facts and projections assumed in granting the approval.
Furthermore, discharge permits and other approvals and licenses are granted
for a term less than the expected life of the associated facility. Licenses
and permits may require periodic renewal, which may result in additional
requirements being imposed by the granting agency. Pacific Gas and Electric
Company currently has ten hydroelectric projects and one transmission line
project undergoing FERC license renewal.

Regulation of the National Energy Group

   In addition to Pacific Gas and Electric Company, certain of PG&E
Corporation's other subsidiaries that conduct interstate gas transmission and
storage and electric wholesale power marketing operations are subject to

                                       4
<PAGE>

FERC jurisdiction. The FERC also has authority to regulate rates for natural
gas transportation and storage in interstate commerce. The FERC also regulates
certain transportation and storage transactions on the intrastate pipelines
pursuant to Section 311 of the Natural Gas Policy Act of 1978.

   The Railroad Commission of Texas (RRC) regulates gas utilities, including
those owned by PG&E Corporation through PG&E Gas Transmission, Texas
Corporation (PG&E GTT), PG&E Gas Transmission Teco, Inc., and other affiliates
operating in Texas. The RRC's gas proration rules govern the wellhead
production and purchase of gas. Intrastate pipelines can provide intrastate
gas transportation at negotiated rates that are presumed just and reasonable.
If the criteria for negotiated rates cannot be met, the RRC may assess a cost-
of-service-based rate. The RRC also may regulate certain sales of gas.
Currently, the price of natural gas sold under a majority of PG&E GTT's gas
sales contracts is not regulated by the RRC. All transportation and gathering
of gas is subject to the RRC Code of Conduct which prohibits undue
discrimination among similarly situated shippers. Further, all transportation
of gas, processing of gas, and transportation of natural gas liquids is
subject to safety regulations enforced by the RRC and the Texas Natural
Resource Conservation Commission.

   In addition, the power generation projects that PG&E Gen develops, manages,
or owns are subject to differing types of federal regulation depending on the
regulatory status of the particular project. Some of these projects are exempt
wholesale generators (EWG) under the National Energy Policy Act of 1992, which
status exempts the project from regulation under the Holding Company Act. EWG
status is granted by the FERC upon application by the project. Some projects
have received authority from the FERC to charge market-based rates for the
power they sell, rather than traditional cost-based rates. Many of PG&E Gen's
affiliated projects are qualifying facilities (QFs) under the Public Utility
Regulatory Policies Act of 1978 (PURPA). QF status exempts the project from
regulation under various federal and state laws concerning the electric
industry. PG&E Gen's projects are also subject to various federal, state, and
local regulations concerning siting and environmental matters.

   PG&E Corporation's indirect subsidiary USGen New England, Inc. (USGenNE)
acquired the electric generating facilities of the New England Electric System
(NEES) in September 1998. USGenNE also is subject to numerous federal, state,
and local statutes and regulations. USGenNE sells at wholesale all of the
electricity it generates, as well as electricity it purchases from third
parties under existing power sales agreements. Under the Federal Power Act
(FPA), the FERC regulates these wholesale sales. The FERC has approved
USGenNE's rate schedule as a market-based schedule and, accordingly, the FERC
granted USGenNE waivers of certain other requirements that otherwise are
imposed on utilities with cost-based rate schedules. In addition, USGenNE owns
and operates a number of hydroelectric and pumped storage projects that are
licensed by the FERC. These licenses expire periodically and the projects must
be relicensed at that time. USGenNE's licenses for these hydroelectric
projects expire over a period from 2001 to 2020. Before expiration of any one
of the hydroelectric licenses, there is an opportunity for the existing
licensee (as well as others interested in owning and operating the project) to
apply for, and obtain, a new license.

   USGenNE also is subject to limited regulation by certain state public
utility commissions located in states where USGenNE owns and operates electric
generating facilities. This regulation does not extend to its rates, which are
regulated exclusively by the FERC, and the scope of this regulation has been
substantially limited by various legislative initiatives.

   Other regulatory matters are described throughout this report.

Risk Management Programs

   PG&E Corporation has an officer-level Risk Management Committee and has
adopted a Risk Management Policy, approved by the Board of Directors of PG&E
Corporation, for trading and risk management activities. The Risk Management
Committee oversees implementation of the policy, approves the trading and risk
management policies of subsidiaries, and monitors compliance with the policy.

                                       5
<PAGE>

   The Risk Management Policy allows derivatives to be used for both hedging
and non-hedging purposes. (A derivative is a contract whose value is dependent
on or derived from the value of some underlying asset.) PG&E Corporation uses
derivatives for hedging purposes primarily to offset underlying commodity
price risks. PG&E Corporation also participates in markets using derivatives
to gather market intelligence, create liquidity, maintain a market presence,
and take a market view. Such derivatives include forward contracts, futures,
swaps, and options. The Risk Management Policy and the trading and risk
management policies of PG&E Corporation's subsidiaries prohibit the use of
derivatives whose payment formula includes a multiple of some underlying
asset. The Risk Management Committee also monitors the trading and risk
management of PG&E ET, consistent with PG&E Corporation's Risk Management
Policy. See "National Energy Group--Energy Trading."

   The CPUC has authorized Pacific Gas and Electric Company to trade natural
gas-based financial instruments to manage price and revenue risks associated
with its natural gas transmission and storage assets, subject to certain
conditions. The CPUC also has authorized the Utility to trade natural gas-
based financial instruments to hedge the gas commodity price swings in serving
core gas customers. In May 1999, the PX obtained FERC approval to operate the
"block forward market" which offers parties the ability to buy and sell
contracts to purchase electricity in the future at prices set in the
contracts. The Utility sought and obtained CPUC authority to participate in
the PX block forward market for contracts that call for delivery of the
purchased electricity by October 31, 2000, as well as to recover costs (such
as gain/losses and transaction fees) associated with its participation in this
market.

   Additional information concerning risk management activities and the
financial impact of risk management activities on PG&E Corporation and Pacific
Gas and Electric Company is provided in "Management's Discussion and Analysis"
in the 1999 Annual Report to Shareholders, beginning on page 5 and in Notes 1,
3, and 4 of the "Notes to Consolidated Financial Statements" beginning on pages
36, 45, and 47, respectively, of the 1999 Annual Report to Shareholders, which
information is hereby incorporated by reference.

                              UTILITY OPERATIONS

   Pacific Gas and Electric Company provides regulated electric and gas
distribution and transmission services in Northern and Central California. The
Utility's service territory covers 70,000 square miles with an estimated
population of approximately 13 million and includes all or portions of 48 of
California's 58 counties. The area's diverse economy includes aerospace,
electronics, financial services, food processing, petroleum refining,
agriculture, and tourism.

Ratemaking Mechanisms

   The ratemaking mechanisms affecting both electricity and gas distribution
operations are discussed below.

   General Rate Case. The CPUC authorizes an amount, known as "base revenues,"
to be collected from ratepayers to recover Pacific Gas and Electric Company's
basic business and operational costs for its gas and electric distribution
operations. Base revenues, which include non-fuel-related operating and
maintenance costs, depreciation, taxes, and a return on invested capital,
currently are authorized by the CPUC in General Rate Case (GRC) proceedings.
During the GRC, which occurs every three years, the CPUC examines the
Utility's costs and operations to determine the amount of base revenue
requirement the Utility is authorized to collect from customers through base
revenues. The revenue requirement is forecasted on the basis of a specified
test year. (The return component of the Utility's revenue requirement is
computed using the overall cost of capital authorized in other proceedings.)
Following the revenue requirement phase of a GRC, the CPUC conducts a rate
design phase, which allocates revenue requirements and establishes rate levels
for the different classes of customers. On February 17, 2000, the CPUC issued
a decision in the Utility's GRC for the period 1999-2001, further discussed
below. The decision also orders that the Utility file a 2002 GRC, so that the
revenue requirements established in the 2002 GRC will be the starting point
for a future performance based ratemaking (PBR) mechanism (discussed below)
that is intended to eventually replace the GRC mechanism and cost of capital
proceedings.

   Cost of Capital. Each year, the Utility files an application with the CPUC
to determine the authorized rate of return that the Utility may earn on its
electric and gas distribution assets and recover from ratepayers. In November
1999, the Utility filed its 2000 cost of capital application. To reflect
increasing interest rates, the Utility has requested a return on equity (ROE)
of 12.5% and an overall rate of return of 9.76% as compared to its 1999
authorized rates of 10.6% ROE and 8.75% overall rate of return. The Utility
has not requested any change in its current authorized capital structure of
46.2% long-term debt, 5.8% preferred stock, and 48% common equity. If granted,
the requested ROE would increase electric distribution revenues by
approximately $36.6 million and natural gas distribution revenues by
approximately $127.8 million based upon the rate base authorized in the 1999
GRC. The Utility requested that a final CPUC decision be issued in June 2000.
On February 17, 2000, the CPUC issued a decision to allow the final CPUC
decision, when it is adopted, to be effective retroactively to February 17,
2000. The return on the Utility's electric transmission-related assets will be
determined by the FERC in 2000. The return on the Utility's natural gas
transmission and storage business was incorporated in rates established in the
Gas Accord settlement. See "Gas Ratemaking--Gas Accord" below. The authorized
ROE for the Utility's remaining generation assets, including Diablo Canyon, is
6.77% throughout the transition period.

   Electric and Gas Distribution Performance-Based Ratemaking. In November
1998, the Utility filed an application with the CPUC to establish performance-
based ratemaking (PBR) for electric and gas distribution services. The
proposed distribution PBR would establish electric and gas distribution
revenue requirements for the year in which PBR is approved to 2004 taking the
place of the GRC and cost of capital proceedings for these years. The Utility
proposed that the revenue requirement for the year 2000 be determined by
applying a formula, based principally on inflation and productivity factors,
to the 1999 GRC authorized revenue requirement. In subsequent years, the
formula would be applied to the previous year's authorized revenue
requirement. The proposed PBR also includes a sharing mechanism for earnings
that are significantly above or below the authorized cost of capital, and a
framework for rewards and penalties based upon the achievement of various
performance measures.

                                       7
<PAGE>

   The final decision in the GRC requires the Utility to go forward with the
performance rewards/penalties framework of its PBR proposal, but it requires a
2002 GRC before implementing the PBR mechanism that determines future revenue
requirements based principally on inflation and productivity factors. The
starting point for the PBR mechanism will be the revenue requirements
established in the required 2002 GRC. In any event, after the transition
period, the Utility's earnings from its electric distribution operations will
be subject to volatility as a result of sales fluctuations.

   Annual Earnings Assessment Proceeding. The Annual Earnings Assessment
Proceeding (AEAP) determines shareholder incentives to be earned for Pacific
Gas and Electric Company's demand side management (DSM) programs. The Utility
was authorized to collect $15.9 million in incentive payments during 1999. The
Utility has filed an application seeking $28.7 million in incentive payments
relating to 1998 energy efficiency and low-income assistance programs, and DSM
programs from other years to be paid in 2000. After consolidating the adjusted
incentive payment installments from prior years, the net revenue change in
2000 from DSM shareholder incentives should be an electric increase of
approximately $2.47 million and a gas decrease of approximately $0.75 million
assuming the Utility's incentive claims are approved. The 1999 AEAP decision
is expected in the second quarter of 2000.

   Catastrophic Event Memorandum Account. The Catastrophic Event Memorandum
Account (CEMA) allows Pacific Gas and Electric Company to track costs incurred
in connection with catastrophic events. On January 7, 1999, the Utility filed
an application with the CPUC in its first CEMA proceeding requesting increases
in electric and gas revenue requirements of $60.1 million and $15.8 million,
respectively, for costs incurred for several emergencies, including the 1991
Oakland Hills Fire and 1998 storms. In September 1999, the Utility entered
into a settlement agreement providing for a $59 million increase in electric
distribution revenue requirement and a $11 million increase in gas
distribution revenue requirement effective January 1, 2000. A CPUC decision is
expected in early 2000.

   Electric Ratemaking

   The California electric industry restructuring legislation provided for a
transition period during which electric customer rates remain frozen. Any
change in the Utility's electric revenue requirements resulting from the items
discussed below will not change electric customer rates. Under the electric
rate freeze, the portion of total actual revenue that exceeds authorized base
revenues and certain other authorized revenue requirements and costs is
available to recover transition costs during the transition period. Transition
costs are certain generation-related costs that prove to be uneconomic under
the new competitive generation market. (See "Electric Utility Operations--
California Electric Industry Restructuring--Recovery of Transition Costs.")
Therefore, increases in base revenues would reduce the amount of revenue
available to recover transition costs. Conversely, decreases in base revenues
would increase revenue available from frozen rates for recovery of transition
costs. The transition period will end the earlier of December 31, 2001, or
when the Utility has recovered its eligible transition costs. The electric
rate freeze will end the earlier of March 31, 2002, or when the Utility has
recovered its eligible transition costs.

   General Rate Case. On February 17, 2000, the CPUC issued a decision in the
Utility's GRC for the period 1999-2001. The decision is retroactive to January
1, 1999. The CPUC authorized increases in base revenues for the Utility's
electric distribution function of $377 million over base revenues authorized
in 1996.

   Revenue Adjustment Proceeding. On January 1, 1998, the Transition Revenue
Account (TRA) was established. The TRA is credited with total revenue
collected from ratepayers through frozen rates. From this total revenue the
following items are subtracted: (1) revenues collected for transmission
services and for the payment of rate reduction bond debt service, (2) the
authorized revenue requirement for distribution services, public purpose
programs, and nuclear decommissioning costs, and (3) electric industry
restructuring implementation costs, energy procurement costs, and other costs.
Remaining revenues, if any, are transferred to the Transition Cost Balancing
Account (TCBA) to offset transition costs. The CPUC established a separate
annual proceeding, the Revenue Adjustment Proceeding (RAP), to review and
verify the amounts recorded in

                                       8
<PAGE>

the TRA, and to verify each electric utility's authorized revenue
requirements, including any necessary adjustments to reflect the revenue
requirements which are approved in other proceedings. The RAP also establishes
revenue allocation and rate design, and identifies all electric balancing and
memorandum accounts for continued retention or elimination. In June 1999, the
CPUC issued a decision in the Utility's first RAP that, among other things,
adopted an agreement between the Utility and the CPUC's Office of Ratepayer
Advocates (ORA) that resolved several rate allocation and rate design issues,
eliminated certain balancing and memorandum accounts, and allows the recovery
of entries made into the TRA from January 1 through May 31, 1998 and certain
other balancing accounts, subject to CPUC audit. On August 9, 1999, the
Utility filed its application in the 1999 RAP addressing revenues and costs
recorded in the TRA from June 1, 1998 through June 30, 1999. A CPUC decision
on this application is expected in late 2000.

   Annual Transition Cost Proceeding. The Annual Transition Cost Proceeding
(ATCP), applicable to all California investor owned electric utilities, was
established to verify the accounting and recording of costs and revenues in
the TCBA and ensure that only eligible transition costs have been entered. The
TCBA tracks the revenues available to offset transition costs, including the
accelerated recovery of plant balances, and other generation-related assets
and obligations. Transition costs will receive a limited "reasonableness"
review. On September 1, 1998, the Utility filed its application in the 1998
ATCP requesting that $1.8 billion of costs recorded in the TCBA from January 1
through June 30, 1998 be approved as eligible for recovery as transition
costs. In July 1999, PG&E and ORA filed a joint motion with the CPUC for
approval of a settlement that recommends that the CPUC approve substantially
all costs requested by the Utility. On February 17, 2000, the CPUC issued a
decision which accepts the settlement in its entirety, and decides most of the
other issues in the case in the Utility's favor. Under the final decision, on
a prospective basis, the utilities are required to assess the estimated market
value of their remaining non-nuclear generating assets, including the land
associated with those assets, on an aggregate basis at a value not less than
the net book value of those assets and to credit the TCBA with the estimated
value. The decision encourages the utilities to base such estimates on
realistic assessments of the market value of the assets. The final decision
did not adopt a recommendation contained in a previously issued proposed
decision to establish a new regulatory asset account that would allow a true-
up when the estimated market value is greater than actual market value.
However, the decision states that crediting the TCBA with the aggregate net
book value of the remaining non-nuclear generating assets is a conservative
approach and remedies any concerns regarding the lack of a true-up. The
decision provides that if the estimated market valuation is less than book
value for any individual asset, accelerated amortization of the associated
transition costs will continue until final market valuation of the asset
occurs through sale, appraisal, or other divestiture. If the final value of
the assets, determined through sale, appraisal or other divestiture, is higher
than the estimate, the excess amount would be used to pay remaining transition
costs, if any. The utilities are required to file the adjusted entries to
their respective TCBA based on the estimated market values with the CPUC by
March 9, 2000. The filing will become effective after appropriate review by
the CPUC's Energy Division and the TCBA entries are subject to review in the
next ATCP. On September 1, 1999, the Utility filed its 1999 ATCP application
requesting that $2.6 billion recorded in the TCBA from July 1, 1998, through
June 30, 1999, be approved as eligible for recovery as transition costs.

   Electric Industry Restructuring Implementation Costs. Under AB 1890,
certain electric industry restructuring implementation costs found reasonable
by the CPUC may be recovered from electric customers. In May 1999, the CPUC
approved a multi-party settlement agreement that, among other things, permits
the Utility to recover 1997 and 1998 restructuring implementation costs of
$41.3 million (reflecting a reduction of $10 million from the Utility's
requested revenue requirement). In addition, the Utility is authorized to
recover in its TRA costs related to the Consumer Education Program and the
Electric Education Trust funded by the Utility and FERC-approved ISO and PX
development and start-up costs. At the end of the transition period, if
recovery of these restructuring implementation costs recorded in the TRA
displaces recovery of transition costs recorded in the TCBA, the Utility may
recover up to $95 million of such displaced transition costs after the
transition period.

   As part of the settlement agreement, the CPUC also authorized the Utility
to establish the Electric Restructuring Costs Account (ERCA) to record the
restructuring implementation costs that were removed from its 1999 GRC revenue
requirement request, any unanticipated restructuring costs incurred as a
result of directives

                                       9
<PAGE>

from the CPUC or the FERC, and certain other costs. The reasonableness of the
entries made in the ERCA and the recovery of these costs will be made through
a separate application by the Utility in 2000.

   Revenues from Must-Run Contracts. The ISO has designated certain units at
electric generation facilities as necessary to remain available to maintain
the reliability of the electric transmission system. These units are called
"must-run" units. In general, the ISO dispatches these units under cost-based
contracts regulated by the FERC that allow the owners to recover a portion of
fixed and operating costs of the must-run units. The owners of must-run units
choose among two different forms of must-run contract, both of which cover
operating costs. One form provides payments of a percentage of the unit's
fixed cost revenue requirement and does not limit market participation. The
other form provides 100% fixed cost recovery but allows only very restricted
market participation. The Utility's two remaining fossil-fueled power plants
(Hunters Point and Humboldt Bay) and three of its hydroelectric generation
facilities are under must-run contracts. The form of must-run contract chosen
for all of these facilities (except Hunters Point) is the one that does not
limit market participation. The Utility currently receives approximately $100
million per year as payments under these must-run contracts, plus fuel costs.
In addition, the Utility has the opportunity to earn market revenues for all
of these plants except Hunters Point when the ISO has not dispatched the
plant. The Utility has filed an application with the CPUC to determine the
market value of its hydroelectric generation facilities and related assets
through an open competitive auction.

   FERC Transmission Owner Rate Case. The ISO controls most of the state's
electric transmission facilities. The Utility serves as the scheduling
coordinator to schedule transmission with the ISO to facilitate continuing
service under wholesale transmission contracts that the Utility entered into
before the ISO was established. The ISO bills the Utility for providing
certain services associated with these contracts. These ISO charges are
referred to as the "scheduling coordinator costs." As part of the Utility's
Transmission Owner rate case filed at the FERC, the Utility established a
balancing account, the Transmission Revenue Balancing Account (TRBA), to
record these scheduling coordinator costs in order to recover these costs
through transmission rates. Certain transmission-related revenues collected by
the ISO and paid to the Utility are also recorded in the TRBA. Through
December 31, 1999, the Utility has recorded approximately $39 million of these
scheduling coordinator costs in the TRBA. (The Utility has also disputed
approximately $22.5 million of these costs as incorrectly billed by the ISO.
Any refunds that ultimately may be made by the ISO would be credited to the
TRBA.). On September 1, 1999, a proposed decision was issued denying recovery
of these scheduling coordinator costs. The proposed decision is subject to
change by the FERC in its final decision. The FERC is expected to issue a
final decision sometime in 2000. On January 11, 2000, the FERC accepted a
proposal by the Utility to establish the Scheduled Coordinator Services (SCS)
Tariff which would act as a back-up mechanism for recovery of the scheduling
coordinator costs if the FERC ultimately decides that these costs may not be
recovered in the TRBA. The FERC also conditionally granted the Utility's
request that the SCS Tariff be effective retroactive to March 31, 1998, but
the FERC suspended the procedural schedule until the final decision is issued
regarding the inclusion of scheduling coordinator costs in the TRBA.

   AB 1890 Electric Base Revenue Increase. AB 1890 provided for an increase in
the Utility's electric base revenues for 1997 and 1998, for enhancement of
transmission and distribution system safety and reliability. The CPUC
authorized a 1997 base revenue increase of $164 million. For 1998, the CPUC
authorized an additional base revenue increase of $77 million. The CPUC will
determine how much of the authorized increases were actually spent on system
safety and reliability during 1997 and 1998, and adjust the amounts downward
if necessary. The Utility claims that it overspent the 1997 authorized revenue
requirement by approximately $11.8 million and that the Utility underspent
1998 incremental revenues by approximately $6.5 million. The Utility has
proposed that the underspent amount be credited to TRA revenues. The CPUC's
Office of Ratepayer Advocate (ORA) has recommended that $88.4 million in
expenditures for 1997 and 1998 be disallowed. The Utility Reform Network
(TURN) has recommended an additional $14 million disallowance for a total
recommended disallowance for 1997 and 1998 expenditures of $102.4 million. The
Utility opposed the recommended disallowances and hearings were held in
October 1999. A proposed decision is not expected until the first quarter of
2000. Any proposed decision would be subject to comment by the parties and
change by the CPUC before a final decision is issued.

                                      10

   Electric Transmission Revenues. Since April 1998, all electric transmission
revenues are authorized by the FERC. During 1998 and 1999, the FERC issued
orders that put into effect various rates to recover electric transmission
costs from the Utility's former bundled rate transmission customers. All 1998
and 1999 rates are subject to refund, pending final decisions. In April 1999,
the Utility filed a settlement with the FERC which, if approved, would allow
the Utility to recover $345 million for the period of April 1998 through May
1999. In May 1999, the FERC accepted, subject to refund, the Utility's March
1999 request to begin recovering, as of May 31, 1999, $324 million annually.
In October 1999, the FERC accepted, subject to refund, the Utility's September
1999 request to increase revenues to $370 million annually beginning in April
2000.

   Electric Deferred Refund Account (EDRA). In December 1996, the CPUC issued
a decision establishing an EDRA. The CPUC ordered the Utility to place into
the EDRA credits for CPUC-ordered electric disallowances, the utility electric
generation share of gas disallowances ordered by the CPUC or the FERC, and
amounts resulting from reasonableness disputes or fuel-related cost refunds
made to the Utility based on regulatory agency decisions, plus interest
charges. In February 2000, the Utility refunded approximately $25 million of
EDRA refunds to customers, which included a refund of unspent research,
development, and demonstration funds.

   Post-Transition Period Ratemaking Proceeding. In October 1999, the CPUC
issued a decision in the Utility's post-transition period ratemaking
proceeding. Among other matters, the CPUC decision addresses the mechanisms
for ending the current electric rate freeze and for establishing post-
transition period accounting mechanisms and rates. The decision prohibits the
Utility from collecting after the rate freeze any electric costs incurred
during the rate freeze but not recovered during the rate freeze, including
costs that are not transition costs and not related to generation assets such
as under-collected accounting balances relating to power purchases. The
decision also requires the discontinuance of Diablo Canyon's performance-based
ratemaking, the incremental cost incentive price (ICIP) mechanism, at the end
of the transition period. Instead, after the transition period, Diablo Canyon
generation must be sold at the prevailing market price for power. The Utility
has filed an application for rehearing of the CPUC's decision.

   In the decision, the CPUC also established the Purchased Electric Commodity
Account (PECA) for the Utility to track energy costs after the rate freeze and
transition period end. The CPUC intends to explore other ratemaking issues,
including whether dollar-for-dollar recovery of energy costs is appropriate,
in the second phase of the post-transition electric ratemaking proceeding.
There are three primary options for the future regulatory framework for
utility electric energy procurement cost recovery after the rate freeze: (1) a
CPUC-defined procurement practice, that if followed by the Utility, would pass
through costs without the need for reasonableness reviews, (2) a pass through
of costs subject to after-the-fact reasonableness reviews, or (3) a
procurement incentive mechanisms with rewards and penalties determined based
on the Utility's energy purchasing performance compared to a benchmark. The
Utility proposed adoption of either a defined procurement practice or a
procurement incentive mechanism, neither of which would involve reasonableness
reviews. The volatility of earnings and risk exposure of the Utility related
to post-transition period purchases of electricity is dependent on which of
these options, or some other approach, is adopted.

   A decision in the second phase of the proceeding is expected in the first
quarter 2000, addressing certain other post-transition period ratemaking
issues including, among others, incentive mechanisms for commodity purchases
and the allocation of certain transition costs that are recoverable after the
transition period.

   Additional information about the financial impact of the end of the rate
freeze and the end of the transition period on the Utility and PG&E
Corporation is provided in "Management's Discussion and Analysis" in the 1999
Annual Report to Shareholders, beginning on page 5.

   Gas Ratemaking

   Gas Accord. The Gas Accord separated or "unbundled" the Utility's gas
transmission services from its distribution services, changed the terms of
service and rate structure for gas transportation, increased the opportunity
for core customers to purchase gas from competing suppliers, established a
form of incentive

                                      11
<PAGE>

mechanism to measure the reasonableness of core procurement costs, and
established gas transmission and storage rates through 2002. Additional
information about the Gas Accord is provided below in "Utility Operations--Gas
Utility Operations" and in "Management's Discussion and Analysis" in the 1999
Annual Report to Shareholders, beginning on page 5.

   General Rate Case. On February 17, 2000, the CPUC issued a decision in the
Utility's GRC for the period 1999-2001. The decision is retroactive to January
1, 1999. The CPUC authorized increases in base revenues for the Utility's gas
distribution function of approximately $93 million over base revenues
authorized in 1996.

   The Biennial Cost Allocation Proceeding (BCAP). The BCAP remains the
proceeding in which distribution costs and balancing account balances are
allocated to customers. The BCAP normally occurs every two years and is
updated in the interim year for purposes of amortizing any accumulation in the
balancing accounts. Balancing accounts for natural gas costs accumulate
differences between the actual recovery of gas costs and the revenues designed
for recovery of such costs. Balancing accounts for sales volumes accumulate
differences between authorized and actual base revenues. In June 1998, the
CPUC adopted a decision in the 1998 BCAP granting an annual $97.8 million
revenue requirement decrease effective September 1, 1998, compared to revenues
established by the Gas Accord on March 1, 1998. The overall annual revenue
requirement for the two-year BCAP period (September 1, 1998, through August
31, 2000) is approximately $1.5 billion, of which an annual average of
approximately $102 million is allocated for the collection of balancing
accounts. The Utility plans to file its 2000 BCAP application in the first
half of 2000.

Electric Utility Operations

   California Electric Industry Restructuring

   As a result of California electric industry restructuring, the electric
generation function of traditional utilities has been opened up to
competition, giving electric customers of investor-owned utilities (such as
Pacific Gas and Electric Company) the choice of continuing to purchase
electricity from investor-owned utilities or purchasing electricity from
alternative providers (including unregulated power generators and unregulated
retail electricity providers such as marketers, brokers, and aggregators).
Purchasing electricity from an alternative generation provider is called
"direct access." For those customers who have not chosen an alternative
generation provider, investor-owned utilities continue to be the generation
provider. Investor-owned utilities continue to provide distribution services
to substantially all customers within their service territories, including
those customers who choose direct access.

   The California Independent System Operator and the California Power
Exchange. To create a competitive generation market, the PX and the ISO were
established and began operating on March 31, 1998. The FERC has jurisdiction
over both the ISO and the PX.

   The ISO operates and controls most of the state's electric transmission
facilities (which continue to be owned and maintained by the California
utilities) and provides comparable open access to electric transmission
service. The ISO accepts balanced supply and load schedules from market
participants and manages the availability of electric transmission on a
statewide basis for these transactions. The ISO also purchases necessary
generation and ancillary services to maintain grid reliability. The ISO is
required to ensure reliable transmission services consistent with planning and
operating reserve criteria no less stringent than those established by the
Western Systems Coordinating Council and the North American Electric
Reliability Council. Oversight of utility distribution systems remains with
the CPUC.

   The PX provides a competitive auction process to establish transparent
market clearing prices for electricity in the markets operated by the PX.
During the transition period, the Utility is required to sell into the PX all
of its generated electric power. "Must-take" generation resources, such as
nuclear generation from Diablo Canyon, electric power generated by QFs and
electricity that the Utility is required to purchase under existing
contractual commitments, also are scheduled through the PX. During the
transition period, the Utility must purchase all

                                      12
<PAGE>

electric power for its retail customers through the PX. Customers who buy
power directly from non-regulated suppliers pay for that generation based upon
negotiated contracts. The PX sets a market-clearing price for electricity by
matching all demand load bids with supply bids ranked from lowest to highest.
The highest-accepted generation supply bid used to serve load sets the PX
market-clearing price for electricity.

   After the transition period, the Utility may continue to schedule its must-
take generation resources into the PX. It is unsettled whether the Utility
will be required to continue purchasing its electric power for its retail
customers through the PX after the transition period. The Utility expects that
the CPUC will address the issue of whether the purchase obligation will
continue through December 31, 2001, if the Utility's rate freeze ends before
that date, in the second phase of the Utility's post-transition period
ratemaking proceeding in the first quarter of 2000. Some parties have argued
that the utilities' purchase obligation may need to continue beyond
December 31, 2001, depending on market conditions. See "Ratemaking
Mechanisms--Electric Ratemaking--Post-Transition Period Ratemaking Proceeding"
above.

   The ISO and PX are California public benefit non-profit corporations. Each
has a Governing Board that includes representatives of investor-owned utility
transmission systems, publicly owned utility transmission systems, non-utility
electricity sellers, public buyers and sellers, private buyers and sellers,
industrial end-users, commercial end-users, residential end-users,
agricultural end-users, public interest groups, and non-market participant
representatives. The ISO and PX currently are overseen by a five-member
Electricity Oversight Board (EOB) that appoints the members of the ISO and PX
Governing Boards. However, this appointment power was rejected by the FERC.
Subsequently the California Legislature passed, and the Governor signed,
Senate Bill (SB) 96 which redefined the relationship between the EOB and the
ISO and PX. SB 96 limits the EOB's appointment power to representatives of
those classes that represent California consumers' interests. The ISO or PX
Governing Boards confirm all other appointments. SB 96 has been accepted in
principle by the FERC. Bylaw amendments implementing SB 96 are pending before
the FERC for the PX and the ISO currently is circulating draft bylaw
amendments among its stakeholders.

   Voluntary Generation Asset Divestiture. California utilities, including
Pacific Gas and Electric Company, have voluntarily begun divesting some of
their generation assets. In 1998, the Utility sold three of its fossil-fueled
electric generating plants located at Morro Bay, Moss Landing, and Oakland,
California. In 1999, the Utility also sold three fossil-fueled generating
facilities (the Pittsburg and Contra Costa power plants located in Contra
Costa County, and the Potrero power plant in San Francisco) and its geothermal
generating facilities (The Geysers Power Plant located in Lake and Sonoma
Counties). The Utility has retained liability for required environmental
remediation of any pre-closing soil or groundwater contamination at these
plants.

   In September 1999, the Utility filed an application with the CPUC to
determine the market value of the Utility's hydroelectric generation
facilities and related assets through an open competitive auction. The Utility
proposes to use an auction process similar to the one previously used in the
sale of the Utility's fossil fueled and geothermal plants. Under the process
proposed in the application. PG&E Gen would be permitted to participate in the
auction on the same basis as other bidders. The sale of the hydroelectric
facilities would be subject to certain conditions, including the transfer or
re-issuance of various permits and licenses by the FERC and other agencies. On
January 13, 2000, the CPUC issued a ruling which separates the proceeding into
two concurrent phases: one to review the potential environmental impacts of
the proposed auction under the California Environmental Quality Act (CEQA) and
a second to determine whether the Utility's auction proposal, or some other
alternative to the proposal, is in the public interest. The ruling sets a
procedural schedule which calls for a final CPUC decision on the Utility's
auction proposal by October 19, 2000, and a final environmental impact report
published in November 2000. The schedule calls for the auction, if approved,
to begin in early November 2000 and end in early January 2001. The schedule
anticipates that the divestiture process would be closed by June 1, 2001.
Finally, the ruling prohibits the Utility from withdrawing its application
without express CPUC authority. It is uncertain whether the CPUC will
ultimately approve the Utility's auction proposal. Additional information
about the potential financial impact of the proposed auction on the Utility
and PG&E Corporation is provided in "Management's Discussion and Analysis" in
the 1999 Annual Report to Shareholders, beginning on page 5.

                                      13
<PAGE>

   As required by AB 1890, Utility employees, under two-year operations and
maintenance agreements with the new owners, will continue to operate and
maintain the power plants that have been sold. To the extent that payments to
the Utility under these agreements exceed the Utility's cost of operating the
plants, the additional revenue would be given to ratepayers. Conversely, to
the extent the Utility's operating costs exceed the revenues from these
agreements, the Utility absorbs these losses in earnings.

   Recovery of Transition Costs. As market-based revenues may not be
sufficient to recover certain of the Utility's generation costs, AB 1890
provides the investor-owned utilities the opportunity to recover such
uneconomic generation costs (called transition costs) for a certain period of
time (the transition period). Some transition costs may be recovered after the
transition period. Costs eligible for recovery as transition costs, as
determined by the CPUC, include (1) above-market sunk costs (i.e., costs
associated with utility generating facilities that are fixed and unavoidable
and that were included in customer rates on December 20, 1995) and future sunk
costs, such as costs related to plant removal, (2) costs associated with long-
term contracts to purchase power at above-market prices from QFs and other
power suppliers, and (3) generation-related regulatory assets and obligations.
(In general, regulatory assets are expenses deferred in the current or prior
periods to be included in rates in subsequent periods.) Transition costs are
eligible for recovery from all customers (with certain exceptions) through a
nonbypassable competition transition charge, or CTC, included as part of
rates. Transition costs that are disallowed by the CPUC for collection from
customers will be written off.

   As a prerequisite to any consumer obtaining direct access services, the
consumer must agree to pay its applicable nonbypassable CTC. Most transition
costs must be recovered by December 31, 2001, although certain transition
costs may be recovered after December 31, 2001. These costs include (1)
certain employee-related transition costs, (2) above-market payments under
existing long-term contracts to purchase power, (3) up to $95 million of
transition costs to the extent that the recovery of such costs during the
transition period was displaced by the recovery of electric industry
restructuring implementation costs, and (4) transition costs financed by the
issuance of rate reduction bonds. In addition, nuclear decommissioning costs
are being recovered through a CPUC-authorized charge, which will extend until
sufficient funds exist to decommission the nuclear facility.

   The total amount of sunk costs to be included as transition costs will be
based on the aggregate of above-market and below-market values of utility-
owned generation assets and obligations. Under AB 1890, valuation of
generation-related assets through appraisal, sale, or other divestiture must
be completed by December 31, 2001. The value of seven of the Utility's power
plants was established when these facilities were sold to third parties. In
October 1998, the CPUC ruled that the market value of the Hunters Point power
plant is zero. In September 1999, the Utility filed an application with the
CPUC to determine the market value of the Utility's hydroelectric generating
facilities and related costs through an open competitive auction.

   Retail Direct Access. Customers participating in direct access may purchase
their electric power directly either through (1) competing non-utility retail
electric providers such as brokers, marketers, aggregators, or other
retailers, or (2) direct negotiated contracts with electric generators. All
customers (with limited exceptions), whether they choose direct access or not,
must pay the nonbypassable CTC, which will be collected by their distribution
utility in connection with recovery of the utilities' transition costs.
Utilities began accepting requests for direct access in November 1997 to
become effective after direct access began. As of February 17, 2000, Pacific
Gas and Electric Company had transferred 94,454 customers to direct access.
The CPUC requires that electric customers with an electricity demand, or load,
of 50 kilowatts (kW) or more must have meters that are capable of providing
hourly data in order to participate in direct access. Those customers with a
load less than 50 kW may participate in direct access either through "load
profiling" or by installing an hourly meter. (Load profiling approximates the
pattern of electricity usage for a given customer class and provides the
equivalent of hourly meter reads.) The customer is responsible for the cost of
the meter and the meter installation.

   Energy service providers supplying the direct access market may choose one
of three billing options: (1) consolidated energy supplier billing, under
which the utility bills the energy supplier for the services provided directly
by the utility to the customer, and the supplier, in turn, provides a
consolidated bill to the customer, (2) consolidated distribution company
billing, under which the utility places the supplier's energy charge on a

                                      14
<PAGE>

distribution bill, or (3) dual billing, under which the energy supplier and
the utility bill separately for their own services. Since January 1, 1999,
energy service providers may provide metering to all of their customers.

   During 1999, the Utility continued its efforts to develop and implement
changes to its business processes and systems, including customer information
and billing systems, to accommodate direct access. To the extent the Utility
is unable to successfully and timely develop and implement such changes, there
could be an adverse impact on PG&E Corporation's and the Utility's future
results of operations.

   Rate Levels and Rate Reduction Bonds. As required by AB 1890, electric
rates for all customers have been frozen at the level in effect on June 10,
1996, and, beginning January 1, 1998, rates for residential and small
commercial customers were reduced by 10% from 1996 levels. The electric rate
freeze and electric rate reduction will continue throughout the transition
period. In 1997, the Utility refinanced the expected 10% rate reduction with
the proceeds from rate reduction bonds. On December 8, 1997, a special purpose
entity established by the California Infrastructure and Economic Development
Bank issued $2.9 billion (the expected revenue reduction from the rate
decrease) of rate reduction bonds on behalf of a wholly owned subsidiary of
the Utility. The bonds were issued in eight classes with maturities ranging
from 10 months to 10 years, and bearing interest at rates ranging from 5.94%
to 6.48%. The Utility is collecting from residential and small commercial
customers a separate nonbypassable charge on behalf of the bondholders to
recover principal, interest, and related costs over the life of the bonds. The
bond proceeds were used by the wholly owned subsidiary to purchase from the
Utility the right to be paid the revenues from this separate charge. The bonds
are secured by the future revenue from the separate charge and not by the
Utility's assets. While the bonds are reflected as long-term debt on the
Utility's balance sheet, the Utility's creditors do not have any recourse to
the revenues from the separate charge. The bonds allow for the rate reduction
by lowering the carrying cost on a portion of the transition costs and by
deferring recovery of a portion of these transition costs until after the
transition period. During the rate freeze, the rate reduction bond debt
service will not increase the Utility customers' electric rates. If the
transition period ends before December 31, 2001, the Utility may be obligated
to return a portion of the economic benefits of the transaction to customers.
The timing of any such return and the exact amount of such portion, if any,
have not yet been determined.

   Public Purpose Programs. Under AB 1890, the Utility is authorized to
collect not less than $198 million in a separate nonbypassable charge included
in frozen electric rates to fund Utility and other entities' investments in
four public purpose programs: (1) cost-effective energy efficiency and energy
conservation programs, (2), research, development and demonstration programs,
(3), renewable energy resources programs, and (4) low-income electricity
programs including targeted energy efficiency services and rate discounts.
Low-income energy efficiency programs are funded at the level of need, but are
not to be funded at less than the 1996 level of expenditures. Under this
provision of AB 1890, the Utility is obligated to fund through electric rates
energy efficiency and conservation programs in an amount not less than $106
million per year, public interest research and development programs at not
less than $30 million per year, renewable energy technologies at not less than
$48 million per year, and low-income energy efficiency programs at not less
than $14 million per year. The Utility also collects funds for the California
Alternate Rates for Energy (CARE) low-income discount rate, a rate subsidy
paid for by the Utility's other customers, which is currently about $31
million per year.

   Under the oversight of the CPUC, the Utility administers both the cost-
effective energy efficiency and low-income energy efficiency programs. These
two programs are reviewed annually in the Annual Earnings Assessment
Proceeding. In March 1999, the CPUC determined that these programs should
continue to be administered by investor-owned utilities, subject to CPUC
oversight, through 2001. Effective January 1, 2000, Section 327 of the
California Public Utilities Code requires utilities to continue to administer
low-income energy efficiency programs. In accordance with AB 1890, the
California Energy Resources Conservation and Development Commission, (also
called the California Energy Commission (CEC)) administers both the public
interest research and development program and the renewable energy program on
a statewide basis. The Utility transfers $78 million per year to the CEC for
these two programs.

   Distributed Generation and Electric Distribution Competition. In October
1999, the CPUC issued a decision outlining how the CPUC, in cooperation with
other regulatory agencies and the California Legislature,

                                      15
<PAGE>

plans to address the issues surrounding distributed generation, electric
distribution competition, and the role of the utility distribution companies
(such as Pacific Gas and Electric Company) in the competitive retail
electricity market. Distributed generation enables siting of electric
generation technologies in close proximity to the electric demand (referred to
as "load"). The CPUC decision opened a new rulemaking proceeding to examine
various issues concerning distributed generation, including interconnection
issues, who can own and operate distributed generation, environmental impacts,
the role of utility distribution companies, and the rate design and cost
allocation issues associated with the deployment of distributed generation
facilities. With respect to electric distribution competition, the CPUC
directed its staff to deliver a report by April 21, 2000 on the different
policy options that the CPUC, in cooperation with the California Legislature,
can pursue. Following the issuance of the report, the CPUC expects to open one
or more new proceedings to address electric distribution competition and
competition in the retail electric market.

Electric Operating Statistics

   At December 31, 1999, Pacific Gas and Electric Company served approximately
4.6 million electric distribution customers.

   During the transition period, the Utility is required to buy from the PX
all electricity needed to provide service to retail customers that continue to
choose the Utility as their electricity supplier. The following table shows
the Utility's operating statistics (excluding subsidiaries) for electric
energy, including the classification of sales and revenues by type of service.

Electric Generating Capacity

   At the beginning of 1999, the Utility's electric generation facilities
included five primarily natural gas-fueled steam power plants with 15 units,
four combustion turbines, two nuclear power reactor units at Diablo Canyon, 67
hydroelectric powerhouses with 107 units, and the Helms hydroelectric pumped
storage plant (Helms) with three units. In 1998, the Utility sold three of its
fossil-fueled power plants. In April and May 1999, the Utility sold three of
its five remaining fossil-fueled power plants, which include 10 steam units
and three combustion turbines, and its geothermal energy complex of 14 units.
Together, the seven divested power plants represented 91% of the Utility's
fossil-fueled generating capacity and all of its geothermal generating
capacity. The facilities generated approximately 31% of the Utility's total
electric energy production.

   The Utility is committed under long-term contracts to purchase power
produced by other generating entities that use a wide array of resources and
technologies, including hydroelectric, wind, solar, biomass, geothermal, and
cogeneration. In addition, the Utility is interconnected with electric power
systems in 14 western states and British Columbia, Canada, for the purposes of
buying, selling, and transmitting power.

   During the transition period, the Utility is required to bid or schedule
into the PX and ISO markets all of the electricity generated by its power
plants and electricity acquired under contractual agreements with unregulated
generators.

Diablo Canyon

   Diablo Canyon Operations

   Diablo Canyon consists of two nuclear power reactor units, each capable of
generating up to approximately 26 million kilowatt-hours (kWh) of electricity
per day. Diablo Canyon Units 1 and 2 began commercial operation in May 1985
and March 1986, respectively. The operating license expiration dates for
Diablo Canyon Units 1 and 2 are September 2021 and April 2025, respectively.
As of December 31, 1999, Diablo Canyon Units 1 and 2 had achieved lifetime
capacity factors of 82% and 83%, respectively.

   The table below outlines Diablo Canyon's refueling schedule for the next
five years. Diablo Canyon refueling outages typically are scheduled every 19
to 21 months. The schedule below assumes that a refueling outage for a unit
will last approximately thirty days, depending on the scope of the work
required for a particular outage. The schedule is subject to change in the
event of unscheduled plant outages.

   Diablo Canyon Ratemaking

   Since January 1, 1997, the Utility's sunk costs in Diablo Canyon are
recovered from ratepayers through a sunk cost revenue requirement, at a
reduced return on common equity equal to 6.77% that will remain in effect
through the end of the transition period. (Sunk costs are costs associated
with the facility that are fixed and unavoidable.) The Diablo Canyon sunk
costs revenue requirement is being recovered as a transition cost through the
TCBA. In connection with the new ratemaking, the CPUC ordered that a financial
verification audit of Diablo Canyon plant accounts be performed by an
independent accounting firm, and that the CPUC hold a proceeding to review the
results of the audit, including any proposed adjustments to Diablo Canyon
accounts, following the completion of the audit. On August 31, 1998, an
independent accounting firm retained by the CPUC completed its financial
verification audit of the December 31, 1996 Diablo Canyon plant accounts. The
audit resulted in the issuance of an unqualified opinion. The audit verified
that Diablo Canyon sunk costs at December 31, 1996, were $3.3 billion of the
total $7.1 billion construction costs. The independent accounting firm also
issued an agreed-upon special procedures report, requested by the CPUC, which
questioned $200 million of the $3.3 billion sunk costs. The CPUC will review
the results of the audit and may seek to make adjustments to Diablo Canyon
sunk costs subject to transition cost recovery. At this time, what action the
CPUC may take regarding the audit, if any, cannot be predicted.

   Also since January 1, 1997, a performance-based Incremental Cost Incentive
Price (ICIP) mechanism has been used to recover Diablo Canyon's operating
costs and the cost of capital additions incurred after December 31, 1996. The
ICIP mechanism establishes a rate per kWh generated by the facility for the
period 1997 through 2001. The CPUC-authorized ICIP prices and revenue
requirement for Diablo Canyon for 2000 and 2001 are shown below. The ICIP
revenues are based on an assumed capacity factor of 83.6%.

</TABLE>

   Any variance between ICIP revenues and related costs is reflected in
earnings. In October 1999, the CPUC issued a decision that will discontinue
the ICIP mechanism after the transition period. After the transition period,
Diablo Canyon generation must be sold at the prevailing market price for
power. The Utility has filed an application for rehearing of this decision.
Further, pursuant to the 1997 CPUC decision establishing the ICIP, the Utility
is required to begin sharing 50% of the net benefits of operating Diablo
Canyon with ratepayers beginning January 1, 2002. The CPUC may interpret a
more recent CPUC decision to require sharing to begin at the end of the
transition period. The Utility is required to file an application with the
CPUC in July 2000 with its proposal for the methods to be used in the
valuation of the benefits associated with the operation of Diablo Canyon and
the mechanism to be used to share these benefits with ratepayers. (See
"Utility Operations--Ratemaking Mechanisms--Electric Ratemaking--Post-
Transition Period Ratemaking Mechanisms" above.)

   Additional information concerning the financial impact of Diablo Canyon
ratemaking is included in "Management's Discussion and Analysis" in the 1999
Annual Report to Shareholders, beginning on page 5, and in Note 2 of the
"Notes to Consolidated Financial Statements" beginning on page 40 of the 1999
Annual Report to Shareholders.

   Nuclear Fuel Supply and Disposal

   Pacific Gas and Electric Company has purchase contracts for, and
inventories of, uranium concentrates, uranium hexaflouride, and enriched
uranium, as well as one contract for fuel fabrication. Based on current Diablo
Canyon operations forecasts and a combination of existing contracts and
inventories, the requirement for uranium

                                      19
<PAGE>

supply will be met through 2004, the requirement for the conversion of uranium
to uranium hexaflouride will be met through 2001, and the requirement for the
enrichment of the uranium hexaflouride to enriched uranium will be met through
2002. The fuel fabrication contract for the two units will supply their
requirements for the next seven operating cycles of each unit. These contracts
are intended to ensure long-term fuel supply, but permit the Utility the
flexibility to take advantage of short-term supply opportunities. In most
cases, the Utility's nuclear fuel contracts are requirements-based, with the
Utility's obligations linked to the continued operation of Diablo Canyon.

   Under the Nuclear Waste Policy Act of 1982 (Nuclear Waste Act), the U.S.
Department of Energy (DOE) is responsible for the transportation and ultimate
long-term disposal of spent nuclear fuel and high-level radioactive waste.
Under the Nuclear Waste Act, utilities are required to provide interim storage
facilities until permanent storage facilities are provided by the federal
government. The Nuclear Waste Act mandates that one or more such permanent
disposal sites be in operation by 1998. Consistent with the law, Pacific Gas
and Electric Company signed a contract with the DOE providing for the disposal
of the spent nuclear fuel and high-level radioactive waste from the Utility's
nuclear power facilities beginning not later than January 1998. However, due
to delays in identifying a storage site, the DOE has been unable to meet its
contract commitment to begin accepting spent fuel by January 1998. Further,
under the DOE's current estimated acceptance schedule for spent fuel, Diablo
Canyon's spent fuel may not be accepted by the DOE for interim or permanent
storage before 2010, at the earliest. At the projected level of operation for
Diablo Canyon, the Utility's facilities are sufficient to store on-site all
spent fuel produced through approximately 2006 while maintaining the
capability for a full-core off-load. It is likely that an interim or permanent
DOE storage facility will not be available for Diablo Canyon's spent fuel by
2006. The Utility is examining options for providing additional temporary
spent fuel storage at Diablo Canyon or other facilities, pending disposal or
storage at a DOE facility.

   In July 1988, the NRC gave final approval to the Utility to store
radioactive waste from the nuclear generating unit (Unit 3) at Humboldt Bay
Power Plant (Humboldt) at Humboldt before ultimately decommissioning the unit.
The Utility has agreed to remove all spent fuel when the federal disposal site
is available.

   Insurance

   Pacific Gas and Electric Company has insurance coverage for property damage
and business interruption losses as a member of Nuclear Electric Insurance
Limited (NEIL). NEIL, which is owned by utilities with nuclear generating
facilities, provides insurance coverage against property damage,
decontamination, decommissioning, and business interruption and/or extra
expenses during prolonged accidental outages for reactor units in commercial
operation. Under these insurance policies, if the nuclear generating facility
of a member utility suffers a loss due to a prolonged accidental outage, the
Utility may be subject to maximum retrospective premium assessments of $15
million (property damage) and $4 million (business interruption), in each case
per one-year policy period, if losses exceed the resources of NEIL.

   The Utility has purchased primary insurance of $200 million for public
liability claims resulting from a nuclear incident. An additional $9.3 billion
of coverage is provided by secondary financial protection required by federal
law and provides for loss sharing among utilities owning nuclear generating
facilities if a costly incident occurs. If a nuclear incident results in
claims in excess of $200 million, the Utility may be assessed up to $176
million per incident, with payments in each year limited to a maximum of $20
million per incident.

   Decommissioning

   Pacific Gas and Electric Company's estimated total obligation to
decommission and dismantle its nuclear power facilities is $1.6 billion in
1999 dollars ($5.1 billion in future dollars). This estimate, which includes
labor, materials, waste disposal charges, and other costs, is based on a 1997
decommissioning cost study. A contingency to capture engineering, regulatory,
and business environment changes is included in the total estimated
obligation. Actual decommissioning costs are expected to vary from this
estimate because of changes in the assumed dates of decommissioning,
regulatory requirements, and technology, as well as differences in the

                                      20
<PAGE>

amount of labor, materials, and equipment needed to complete decommissioning.
The estimated total obligation needed to complete decommissioning is
recognized proportionately over the license term of each facility.

   Nuclear decommissioning costs recovered in rates are placed in external
trust funds. These funds, along with accumulated earnings, will be used
exclusively for decommissioning and dismantling the nuclear facilities. The
trust funds maintain substantially all of their investments in debt and equity
securities. All earnings on the trust fund, net of authorized disbursements
from the trusts and management and administrative fees, are reinvested. Monies
may not be released from the external trust funds until authorized by the
CPUC. In December 1997, the CPUC granted the Utility's request for authority
to disburse up to $15.7 million from the Humboldt Bay Power Plant
decommissioning trust funds to finance three partial nuclear decommissioning
projects at Humboldt Bay Power Plant Unit 3. Accordingly, as of December 31,
1999, $9.3 million (net of taxes) has been disbursed from the Humboldt Bay
Power Plant Unit 3 non-tax-qualified trust to reimburse the Utility for
nuclear decommissioning expenses associated with the partial decommissioning
projects. The remaining $6.4 million of the approved expenses is expected to
be funded with associated tax savings.

   In its 1999 GRC, Pacific Gas and Electric Company sought approval from the
CPUC to use the tax savings resulting from the payment of tax-deductible
nuclear decommissioning expenses from the Humboldt Bay Power Plant Unit 3 non-
tax-qualified trust to fund nuclear decommissioning work. The CPUC found that
the Utility's recommended approach of using the tax benefit to fund
decommissioning activity was reasonable and approved the Utility's request.

   As of December 31, 1999, the Utility had accumulated external trust funds
with an estimated fair value of $1.3 billion, based on quoted market prices
and net of deferred taxes on unrealized gains, to be used for the
decommissioning of the Utility's nuclear facilities.

   The amount recovered in rates for nuclear decommissioning costs is
authorized by the CPUC as part of the GRC. The CPUC considers the trusts'
asset levels, together with revised earnings and decommissioning cost
assumptions, to determine the amount of decommissioning costs it will
authorize in rates for contribution to the trusts. The monies contributed to
the decommissioning trusts, together with existing trust fund balances and
projected earnings, are intended to satisfy the estimated future obligation
for decommissioning costs. For the year ended December 31, 1999, annual
nuclear decommissioning trust contributions collected in rates were
$26.47 million.

   Since January 1, 1998, nuclear decommissioning costs, which are not
transition costs, have been recovered through a nonbypassable charge that will
continue until those costs are fully recovered. Recovery of decommissioning
costs may be accelerated to the extent possible under the rate freeze. The
CPUC has established a Nuclear Decommissioning Costs Triennial Proceeding to
determine the decommissioning costs and to establish the annual revenue
requirement and attrition factors over subsequent three-year periods when and
if GRCs are discontinued.

   QF Generation and Other Power Purchase Contracts

   By federal law, Pacific Gas and Electric Company is required to purchase
electric energy and capacity provided by independent power producers that are
qualifying facilities (QFs) under the Public Utility Regulatory Policies Act
of 1978 (PURPA). The CPUC established a series of QF long-term power purchase
contracts and set the applicable terms, conditions, price options, and
eligibility requirements. Under these contracts, the Utility is required to
make payments only when energy is supplied (an "energy payment") or when
capacity commitments are met (a "capacity payment"). Costs associated with
these contracts to purchase power are eligible for recovery by the Utility as
transition costs through the collection of the nonbypassable CTC. The
Utility's contracts with these power producers expire on various dates through
2028. Deliveries from these power producers account for approximately 23% of
the Utility's 1999 electric energy requirements and no single contract
accounted for more than 5% of the Utility's energy needs.

                                      21
<PAGE>

   The Utility has negotiated with several QFs for early termination of their
power purchase contracts. For other contracts, the Utility has negotiated with
QFs to refrain from producing energy during the remaining term of the higher
fixed energy price period under their contract (a "buy-down") or to curtail
energy production for shorter periods of time (a "curtailment"). At December
31, 1999, the total discounted future payments due under the renegotiated
contracts that are subject to early termination, buy-down or curtailment, was
$16 million. Of the $16 million, the Utility has recovered $6.6 million in
rates and expects to recover the remaining $9.4 million in future rates.

   As of December 31, 1999, the Utility had commitments to purchase
approximately 5,200 MW of capacity under CPUC-mandated power purchase
agreements. Of the 5,200 MW, approximately 4,500 MW are operational.
Development of the majority of the balance is uncertain and it is estimated
that very few of the remaining contracts will become operational. The 4,500 MW
of operational capacity consists of 2,800 MW from co-generation projects, 700
MW from wind projects, and 1,000 MW from other projects, including biomass,
waste-to-energy, geothermal, solar, and hydroelectric.

   The Utility also has contracts with various irrigation districts and water
agencies to purchase hydroelectric power. Under these contracts, the Utility
must make specified semi-annual minimum payments whether or not any energy is
supplied (subject to the supplier's retention of the FERC's authorization) and
variable payments for operation and maintenance costs incurred by the
suppliers. These contracts expire on various dates from 2004 to 2031. Costs
associated with these contracts to purchase power are eligible for recovery by
the Utility as transition costs through the collection of the nonbypassable
CTC. At December 31, 1999, the undiscounted future minimum payments under
these contracts are approximately $32.7 million for each of the years 2000
through 2004 and a total of $280 million for periods thereafter. Irrigation
district and water agency deliveries in the aggregate account for
approximately 5.8% of the Utility's 1999 electric energy requirements.

   The amount of energy received and the total payments made under all these
power purchase contracts were:

Electric Transmission and Distribution

   To transport energy to load centers, Pacific Gas and Electric Company as of
December 31, 1999, owned approximately 18,624 circuit miles of interconnected
transmission lines of 60 kilovolts (kV) to 500 kV and transmission substations
having a capacity of approximately 42,106,600 kilovolt-amperes (kVa),
including spares, excluding power plant interconnection facilities. Energy is
distributed to customers through approximately 113,289 circuit miles of
distribution system and distribution substations having a capacity of
approximately 23,773,000 kVa.

   In 1998, the utilities relinquished control, but not ownership, of their
transmission facilities to the ISO. The ISO commenced operations on March 31,
1998. The ISO, regulated by the FERC, controls the operation of the
transmission system and provides open access transmission service on a
nondiscriminatory basis. In 1998, the FERC approved the various forms of
agreements for must-run facilities that have been entered into between the
utilities and the ISO to ensure grid reliability.

   The FERC also has approved a proposal from Pacific Gas and Electric Company
and the other California utilities that distinguishes between local
distribution facilities and transmission facilities. The FERC will have
jurisdiction over the transmission facilities as defined in the order and over
the transmission aspects of direct access. Most of the Utility's distribution
services remain subject to CPUC jurisdiction.

                                      22
<PAGE>

   The CPUC is considering whether it should pursue further reforms in the
structure and regulatory framework governing electricity distribution service.
See "Utility Operations--Electric Utility Operations--California Electric
Industry Restructuring" above.

   During 1999, the Utility and various other parties, including the ISO and
the CPUC, issued reports on their investigation into the power outage that
occurred on December 8, 1998, in the San Francisco Bay area. In March 1999,
the ISO issued its report on the outage that concluded that the Utility's
system was designed in accordance with industry standards and responded as
expected under the circumstances. The ISO's report identified a number of
measures for the Utility to undertake to minimize the likelihood of a similar
event occurring in the future. Reports by other parties, including the CPUC,
have also recommended corrective measures. Since the outage, the Utility has
revised its grounding and switching procedures as preventive measures to
minimize the risk that the type of initiating event that caused the outage
could occur in the future. On October 20, 1999, the Utility submitted a report
to the CPUC describing how its corrective actions implements the ISO's
recommendations, and responds to the other parties' recommendations. The CPUC
is currently holding workshops to address the issues in the proceeding. After
the conclusion of the workshops, the CPUC plans to convene another prehearing
conference to discuss how to address any remaining issues.

Gas Utility Operations

   Pacific Gas and Electric Company owns and operates an integrated gas
transmission, storage, and distribution system in California. The Utility
served approximately 3.8 million gas customers at December 31, 1999. Most of
these customers continue to obtain gas supplies from the Utility under
regulated tariff rates.

   At December 31, 1999, the Utility's system, including the PG&E Expansion
(Line 401), consisted of approximately 6,225 miles of transmission pipelines,
three gas storage facilities, and approximately 37,487 miles of gas
distribution lines. The PG&E Expansion is the Utility's portion of an
expansion of the interconnected natural gas transmission systems of the
Utility and PG&E Gas Transmission, Northwest Corporation (PG&E GT-Northwest)
which extends from the Canadian border into California (Pipeline Expansion).
Including the portion owned by PG&E GT-Northwest (PG&E GT-NW Expansion), the
840-mile combined Pipeline Expansion provides an additional 148 million cubic
feet per day (MMcf/d) of firm capacity to the Pacific Northwest and an
additional 851 MMcf/d of capacity to Northern and Southern California. The Gas
Accord resolved various issues concerning the PG&E Expansion and also
established certain rules for ratemaking and terms of service applicable to
the PG&E Expansion.

   The Utility's peak day send-out of gas on its integrated system in
California during the year ended December 31, 1999, was 3,503 million cubic
feet (MMcf). The total volume of gas throughput during 1999 was approximately
840,000 MMcf, of which 309,000 MMcf was sold to direct end-use or resale
customers, 47,000 MMcf was used by the Utility primarily for its fossil-fueled
electric generating plants, and 484,000 MMcf was transported as customer-owned
gas.

   The California Gas Report, which presents the outlook for natural gas
requirements and supplies for California over a long-term planning horizon, is
prepared annually by the California electric and gas utilities as a result of
a CPUC order. A comprehensive biennial report is prepared in even-numbered
years with a supplemental report in intervening odd-numbered years updating
recorded data for the previous year.

   The 1998 California Gas Report updates the Utility's annual gas
requirements forecast (excluding bypass volumes) for the years 1999 through
2015, forecasting average annual growth in gas throughput served by the
Utility of approximately 1.5%. The gas requirements forecast is subject to
many uncertainties and there are many factors that can influence the demand
for natural gas, including weather conditions, level of utility electric
generation, fuel switching, and new technology. In addition, some large
customers, mostly in the industrial and enhanced oil recovery sectors, may
have the ability to use unregulated private pipelines or interstate pipelines,
bypassing the Utility's system entirely.

Natural Gas Supplies

   The objective of Pacific Gas and Electric Company's Gas Procurement
Department is to maintain a balanced supply portfolio that provides supply
reliability and contract flexibility, minimizes costs, and fosters competition
among the Utility's gas suppliers. To ensure a diverse and competitive mix of
natural gas supplies to serve the Utility's customers, the Utility purchases
gas directly from producers and marketers in both Canada and the United States.

   Under current CPUC regulations, the Utility purchases natural gas from its
various suppliers based on economic considerations, consistent with regulatory,
contractual, and operational constraints. During the year ended December 31,
1999, approximately 65% of the Utility's total purchases of natural gas
consisted of Canadian-sourced gas transported by Canadian pipeline companies
and PG&E GT-Northwest and Rocky Mountain-sourced gas transported by PG&E GT-
Northwest, approximately 5% was purchased in California, approximately 22% was
purchased in the U.S. Southwest and was transported primarily by the El Paso
Natural Gas Company and Transwestern Pipeline Company pipelines, and
approximately 8% was purchased in the Rocky Mountains and transported by Kern
River Gas Transmission Company. California purchases include supplies from
various California producers and supplies transported into California by
others. The following table shows the total volume and average price of gas in
dollars per thousand cubic feet (Mcf) purchased by the Utility from these
sources during each of the last five years.

(1) The average prices for Canadian and U.S. Southwest gas include the
    commodity gas prices, interstate pipeline demand or reservation charges,
    transportation charges, and other pipeline assessments, including direct
    bills allocated over the quantities received at the California border.
    Beginning March 1, 1998, the average price for gas also includes intrastate
    pipeline demand and reservation charges. These costs previously were
    bundled in gas rates.

Gas Regulatory Framework

   In August 1997, the CPUC approved the Gas Accord, which restructured Pacific
Gas and Electric Company's gas services and its role in the gas market. Among
other matters, the Gas Accord separates, or "unbundles," the rates for the
Utility's gas transmission services from its distribution services. As a result
of

                                       25
<PAGE>

the Gas Accord, the Utility's customers may buy gas directly from competing
suppliers and purchase transmission-only and distribution-only services from
the Utility. Most of the Utility's industrial and larger commercial customers
(noncore customers) now purchase their gas from marketers and brokers.
Substantially all residential and smaller commercial customers (core
customers) buy gas as well as transmission and distribution services from the
Utility as a bundled service. Customer rates for gas are updated on a monthly
basis to reflect changes in the Utility's gas procurement costs. The Gas
Accord established an incentive mechanism (the core procurement incentive
mechanism or CPIM) for recovery of the Utility's core gas procurement costs as
described below.

   The Gas Accord also established gas transmission and storage rates for the
period from March 1998 through December 31, 2002. Rates for gas distribution
service continue to be set by the CPUC in BCAP proceedings, and are designed
to provide the Utility an opportunity to recover its costs of service and
include a return on investment. See "Utility Operations--California Ratemaking
Mechanisms--Gas Ratemaking--The Biennial Cost Allocation Proceeding (BCAP)."

   The CPUC is considering further changes in California's natural gas
industry. Additional information concerning gas industry restructuring, and
the financial impact of these changes on PG&E Corporation, is provided in
"Management's Discussion and Analysis" in the 1999 Annual Report to
Shareholders, beginning on page 5.

Transportation Commitments

   Pacific Gas and Electric Company has gas transportation service agreements
with various Canadian and interstate pipeline companies. These agreements
include provisions for payment of fixed demand charges for reserving firm
capacity on the pipelines. The total demand charges that the Utility will pay
each year may change due to changes in tariff rates. The total demand and
volumetric transportation charges paid by the Utility under these agreements
were approximately $97 million in 1999. This amount includes payments made to
PG&E GT-Northwest of approximately $47 million in 1999, which are eliminated
in the consolidated financial statements of PG&E Corporation.

   As a result of regulatory changes, the Utility no longer procures gas for
most of its noncore customers, resulting in a decrease in the Utility's need
for firm transportation capacity for its gas purchases. The Utility continues
to procure gas for almost all of its core customers and those noncore
customers who choose bundled service (core subscription customers). The
Utility is continuing its efforts to broker or assign any of its remaining
contracted-for but unused interstate and Canadian transportation capacity,
including unused capacity held for its core and core-subscription customers.

   Under a firm transportation agreement with PG&E GT-Northwest that runs
through October 31, 2005, the Utility currently retains capacity of
approximately 600 MMcf/d on the PG&E GT-Northwest system to support its core
and core-subscription customers. The Utility has been able to broker its
unused capacity on PG&E GT-Northwest's system, when not needed for core and
core-subscription customers.

   In 1992, the Utility entered into a firm transportation agreement with
Transwestern Pipeline Company (Transwestern), which expires in 2007, to hold
capacity to meet core gas sales demands and electric generation needs. Since
the Utility has sold most of its fossil-fueled generating plants in connection
with electric industry restructuring and no longer needs natural gas for
electric generation, the Utility permanently released 50 MMcf/d of firm
capacity under this contract. As a result, the demand charges associated with
the entire Transwestern capacity currently approximate $22 million per year.
The Utility may recover demand charges through the CPIM and through brokering
activities.

Core Procurement Incentive Mechanism

   The Utility's core gas procurement costs through 2002 are recoverable in
rates under the CPIM, which provides the Utility with a direct financial
incentive to procure gas and transportation services at the lowest reasonable
costs. Under the CPIM, all Utility procurement costs are compared to an
aggregate market-based benchmark. If costs fall within a range (tolerance
band) around the benchmark, costs are deemed reasonable and fully recoverable
from ratepayers. If procurement costs fall outside the tolerance band, the
Utility's ratepayers and shareholders share savings or costs, respectively.
Under the Gas Accord and CPIM mechanism, all Utility procurement costs from
June 1, 1994 to October 31, 1998, were approved by the CPUC as reasonable. For
the period from December 1, 1997 to October 31, 1998, the CPUC, with ORA
support, has recognized savings outside of the tolerance band, and for that
period has awarded approximately $2 million of the savings to shareholders. In
January 2000, the Utility filed a CPIM performance report for the period of
November 1, 1998, through October 31, 1999. The report determined that all gas
commodity and transportation costs for the period were within the tolerance
band, and therefore should be deemed reasonable and recoverable in full from
ratepayers.

                             NATIONAL ENERGY GROUP

   PG&E Corporation's National Energy Group has been formed to pursue
opportunities created by the gradual deregulation of the energy industry
across the nation. The National Energy Group integrates PG&E Corporation's
national power generation, gas transmission, and energy trading and services
businesses. The National Energy Group contemplates increasing PG&E
Corporation's national market presence through a balanced program of
acquisition and development of energy assets and businesses, while at the same
time undertaking ongoing portfolio management of its assets and businesses.
PG&E Corporation's ability to anticipate and capture profitable business
opportunities created by deregulation will have a significant impact on PG&E
Corporation's future operating results.

Gas Transmission Operations

   PG&E Corporation participates in the "midstream" portion of the gas
business through PG&E GT. PG&E GT consists of three principal entities: PG&E
Gas Transmission, Texas Corporation, PG&E Gas Transmission Teco, Inc., and
PG&E GT-Northwest. PG&E Gas Transmission, Texas Corporation and PG&E Gas
Transmission Teco, Inc. are referred to collectively as PG&E Gas Transmission,
Texas (PG&E GTT). The "midstream" gas business includes (1) gas gathering,
processing, storage, and transportation of natural gas and natural gas liquids
(NGLs), and (2) the marketing of natural gas and NGLs. PG&E GT's gas
transmission facilities are operated through offices in various cities,
including Houston and San Antonio, Texas and Portland, Oregon.

   PG&E GT competes with, among others, major interstate and intrastate
pipeline companies in the transportation of natural gas and NGLs. The
principal elements of competition among pipeline companies are rates, terms of
service, flexibility, and reliability of service. Natural gas competes with
other forms of energy available to PG&E GT's customers and end-users,
including electricity, coal, and fuel oils. A significant competitive factor
is price. Changes in the availability or price of natural gas and other forms
of energy, the level of business activity, conservation, legislation, and
governmental regulations, the capability to convert to alternative fuels, and
other factors, including weather, affect the demand for natural gas.

   PG&E GT also competes with, among others, major integrated energy
companies, the marketing affiliates of the major interstate and intrastate
pipelines, national and local gas gatherers, brokers, marketers, and
distributors for natural gas supplies, in gathering and processing natural gas
and in marketing natural gas and NGLs. Competition for natural gas supplies is
based on a number of factors, including flexibility in contract terms and
conditions, reliability, availability of transportation, and price for the
natural gas and NGLs. Competition for sales customers is based upon, among
other factors, flexibility of contract terms and conditions, reliability and
price of delivered natural gas and NGLs.

   PG&E Gas Transmission, Texas

   PG&E GTT owns and operates gas gathering, transportation, and processing
facilities, and NGL pipelines. The NGL business includes the gathering of
natural gas, the extraction of NGLs from natural gas, the fractionation of
mixed NGLs into component products (e.g., ethane, propane, butane, and natural
gasoline), and the transportation and marketing of NGLs. The Texas operations
include approximately 6,700 miles of natural gas pipelines and joint ownership
or leasehold interests in approximately 1,300 miles of pipelines, including
pipelines from Waha in west Texas to the Katy area near Houston, Texas. These
pipeline systems have the capacity to transport more than 3 billion cubic feet
(bcf) of gas per day. The Texas assets also include approximately 536 miles of
NGL pipelines and nine natural gas processing plants with a combined capacity
of approximately 1.6 bcf per day of gas throughput, capable of producing
approximately 100,000 barrels per day of NGLs, and a long-term lease of 7.2
bcf of storage capacity. PG&E GTT participates in all areas of the midstream
portion of the gas business. PG&E GTT markets gas to gas distribution
companies, electric utilities, municipalities, marketers, independent power
producers, and end-use customers. It also transports natural gas for these
customers, producers, and other pipelines, and markets and transports NGLs to
various customers, including end-use customers.

   On January 27, 2000, PG&E Corporation's National Energy Group signed a
definitive agreement with El Paso Field Services Company providing for the
sale to El Paso Field Services Company, a subsidiary of El Paso Energy
Corporation, of the stock of PG&E Gas Transmission, Texas Corporation and PG&E
Gas Transmission Teco, Inc. (collectively PG&E GTT). Closing of the sale,
which is expected near the end of the first half of 2000, is subject to
approval under the Hart Scott Rodino Act.

   Additional information concerning the sale of PG&E GTT is provided in
"Management's Discussion and Analysis" in the 1999 Annual Report to
Shareholders, beginning on page 5, and in Note 5 of the "Notes to Consolidated
Financial Statements" beginning on page 47 of the 1999 Annual Report to
Shareholders.

   PG&E GT-Northwest

   PG&E GT-Northwest owns and operates gas transmission pipelines and
associated facilities which extend over 612 miles from the Canada-U.S. border
to the Oregon-California border. PG&E GT-Northwest participates in the
midstream portion of the gas business by providing firm and interruptible
transportation services to third party shippers on an open access,
nondiscriminatory basis. Its customers are principally retail gas distribution
utilities, electric utilities that use natural gas to generate electricity,
natural gas marketing companies, natural gas producers, and industrial
companies. PG&E GT-Northwest's largest customer in 1999 was Pacific Gas and
Electric Company, accounting for approximately $49 million, or 23.5% of its
transportation revenues.

   PG&E GT-Northwest's mainline system is composed of two parallel pipelines
with 12 compressor stations totaling approximately 408,660 International
Standards Organization (ISO) installed horsepower and ancillary facilities,
including metering, regulating facilities, and a communications system. The
dual pipeline system consists of approximately 639 miles of 36-inch diameter
gas transmission line (612 miles of single 36-inch diameter pipe and 27 miles
of 36-inch diameter pipeline looping) and approximately 590 miles of 42-inch
diameter pipe. In addition, in 1995, PG&E GT-Northwest constructed two lateral
pipeline extensions, adding approximately 84 miles of 12-inch diameter pipe,
and 22 miles of 16-inch diameter pipe to serve its customers on those
laterals.

   PG&E GT-Northwest's total transportation quantities for 1995 through 1999
are set forth in the following table.

   PG&E GT-Northwest's current rates were set in a rate settlement approved by
the FERC in September 1996. In 1998, petitions filed by various parties for
rehearing of the FERC order approving the settlement were denied. Three
parties have appealed the FERC's denial of these rehearing petitions to the
U.S. Court of Appeals for the District of Columbia Circuit. On February 1,
2000, the appellate court denied the petitions for review and reaffirmed the
FERC settlement.

Independent Power Generation

   Through PG&E Gen and its affiliates, PG&E Corporation participates in the
development, construction, operation, ownership, and management of non-utility
electric generating facilities that compete in the United States power
generation market. PG&E Gen is headquartered in Bethesda, Maryland.

   As of December 31, 1999, PG&E Gen affiliates had ownership interests in 30
operating plants in 10 states. The total generating capacity of these 30
plants is approximately 6,560 MW. Ten of these plants operate as QFs with a
combined capacity of 2,128 MW which is sold at fixed prices under long-term
power purchase agreements. The remaining plants with a combined capacity of
4,435 MW are operated as merchant power plants that sell their power directly
to wholesale customers (including other PG&E Corporation affiliates) at
prevailing market prices. PG&E Corporation's combined net equity ownership and
leased interest in these plants as of December 31, 1999, represented
approximately 5,200 MW. The plants were financed largely with a combination of
non-recourse debt and equity or equity commitments from the project sponsors.
PG&E Gen, through its affiliate, PG&E Operating Services Company (PG&E OSC),
provides contract operations and maintenance services to many of these
facilities. PG&E Gen also manages power purchase agreements with an aggregate
of 789 MW of capacity. PG&E Gen and its affiliated or managed facilities sold
29,187,905 megawatt-hours (MWh) of electricity in 1999. PG&E Gen also is
engaged in the "greenfield" development of new merchant power plants, as
discussed below.

   PG&E Gen competes with unaffiliated utilities and other independent power
producers.

   New England Operations

   In 1998, PG&E Corporation, through its indirect subsidiary, USGenNE,
purchased from the New England Electric System (NEES) a portfolio of electric
generating assets with a combined generating capacity of about 4,000 MW. In
addition, USGenNE assumed NEES' obligations to purchase power from various
independent power producers (IPPs). As of December 31, 1999 these power
purchase obligations represented an additional 470 MW of production capacity.
NEES is required to make annual support payments to USGenNE through early 2008
to offset the cost of power associated with these above-market contracts.
Finally, in connection with the NEES acquisition, USGenNE obtained the right
to purchase NEES's nuclear generated electric energy, capacity, and associated
products at market prices up to the entire amount available. In December 1999,
USGenNE sold these nuclear entitlements.

   Three of the four states in which USGenNE operates generation facilities
(Massachusetts, Rhode Island, and New Hampshire) were, like California, among
the first states in the country to introduce retail competition. As part of
electric industry restructuring in these New England states, local utility
companies were required to offer standard offer service (SOS) to their retail
customers. Retail customers may select alternate suppliers at any time. The
SOS is intended to provide customers with a price benefit (the commodity
electric price offered to the retail customer under SOS is expected to be less
than the market price for the first several years), followed by a price
disincentive that is intended to stimulate the retail market. Connecticut also
has passed retail competition legislation.

   The New England assets are located within the New England Power Pool
(NEPOOL). The wholesale electricity market in New England features a bid-
based, real-time pricing structure. Traditionally, NEPOOL has operated as a
"tight power pool," one in which the utilities within the pool dedicate their
generation resources to be centrally dispatched. Dispatch starts with the
lowest-cost generation and ends with the highest-cost generation. An
independent system operator for the New England states (ISO-NE) provides
central dispatch service and operates the power pool as a competitive
wholesale marketplace. The duties of the ISO-NE include scheduling the
operations of the regional transmission systems and, importantly, operating a
power exchange for seven generation products (the "Interchange"). These
products are energy, installed (monthly) capacity and operable (hourly)
capacity, three types of reserves, and automatic generation control
(adjustment of generators to meet the second-to-second changes in electric
load).

   Generation Development Projects

   Nationwide, PG&E Gen's greenfield power plant development activities exceed
10,000 MW in 9 states. The table below lists PG&E Gen's development projects.
The Millennium Project in Charlton, Massachusetts (360 MW) and the Lake Road
Project in Killingly, Connecticut (792 MW) are under construction. The La
Paloma Project in McKittrick, California (1,048 MW) has been approved by PG&E
Corporation's Board of Directors and the California Energy Commission. The
other development projects listed below are in the early stages of the
development process. The completion of these planned projects is subject to
many factors, including but not limited to various regulatory and
environmental approvals, adequate financing on satisfactory terms, competitive
conditions including the expansion and retirement plans of others, market
prices for electricity, and future fuel prices.

Energy Trading

   PG&E Energy Trading-Gas Corporation and PG&E Energy Trading-Power, L.P.
(also collectively referred to as PG&E ET), headquartered in Houston, Texas,
purchase electric power from PG&E Corporation affiliates and the wholesale
market and natural gas from producers, marketers, and other parties. PG&E ET
then schedules, transports, and resells these commodities, either to third
parties or to other PG&E Corporation affiliates (except the Utility). PG&E ET
also provides risk management services to PG&E Corporation's other businesses
(except the Utiltiy) and to unaffiliated wholesale customers. For more
information, see "General--Risk Management Programs" above.

   PG&E ET competes with, among others, major integrated energy companies,
marketing affiliates of major interstate pipelines, brokers, gas marketers,
and gas distributors for natural gas supplies and/or in marketing natural gas.
In addition, PG&E ET competes with unaffiliated electric utilities, marketers,
and other entities in purchasing and selling electric power and other energy
commodities. Competition in the energy marketing business is driven by various
factors, including the price of commodities and services delivered along with
quality and reliability of services delivered.

   Additional information concerning the wholesale operations of PG&E
Corporation's affiliates is provided in "Management's Discussion and Analysis"
in the 1999 Annual Report to Shareholders, beginning on page 5, and in Note 17
of the "Notes to Consolidated Financial Statements" beginning on page 63 of
the 1999 Annual Report to Shareholders.

Energy Services

   PG&E Energy Services (PG&E ES), headquartered in San Francisco, California,
provides retail gas and electric commodities nationwide, where permitted under
applicable laws, and provides energy-related value-added services, including
billing and information management services, energy efficiency and other
energy management services, regulatory and rate analysis, and power quality
solutions. PG&E ES targets primarily industrial, commercial, and institutional
customers, offering comprehensive energy management solutions to reduce their
energy costs and improve their productivity. PG&E ES has 20 offices nationwide
to support its sales activities. PG&E ES currently competes with other non-
utility electric retailers in California for direct access customers. See
"Utility Operations--Electric Utility Operations--California Electric Industry
Restructuring" above.

   In December 1999, PG&E Corporation's Board of Directors approved a plan to
dispose of PG&E ES, its wholly owned subsidiary, through a sale. The intended
disposal has been accounted for as a discontinued operation in PG&E
Corporation's 1999 financial statements. While there is no definitive sales
agreement, it is expected that the disposition will be completed by June 2000.
Additional information concerning PG&E ES is provided in "Management's

                             ENVIRONMENTAL MATTERS

Environmental Matters

   The following discussion includes certain forward-looking information
relating to estimated expenditures for environmental protection measures and
the possible future impact of environmental compliance. This information below
reflects current estimates, which are periodically evaluated and revised.
Future estimates and actual results may differ materially from those indicated
below. These estimates are subject to a number of assumptions and
uncertainties, including changing laws and regulations, the ultimate outcome
of complex factual investigations, evolving technologies, selection of
compliance alternatives, the nature and extent of required remediation, the
extent of the facility owner's responsibility, and the availability of
recoveries or contributions from third parties.

   PG&E Corporation, the Utility, PG&E Gen and its affiliates (including
USGenNE), and other PG&E Corporation subsidiaries and affiliates are subject
to a number of federal, state, and local laws and regulations designed to
protect human health and the environment by imposing stringent controls with
regard to planning and construction activities, land use, air and water
pollution, and treatment, storage, and disposal of hazardous or toxic
materials. These laws and regulations affect future planning and existing
operations, including environmental protection and remediation activities. The
Utility has undertaken compliance efforts with specific emphasis on its
purchase, use, and disposal of hazardous materials, the cleanup or mitigation
of historic waste spill and disposal activities, and the upgrading or
replacement of the Utility's bulk waste handling and storage facilities. The
costs of compliance with environmental laws and regulations generally have
been recovered in rates.

   Although the Utility has sold most of its fossil-fueled power plants and
its geothermal generation facilities in connection with electric industry
restructuring, the Utility has retained liability for certain required
environmental remediation of pre-closing soil or groundwater contamination for
fossil and geothermal generation facilities that have been sold. See "Utility
Operations--Electric Utility Operations--California Electric Industry
Restructuring--Voluntary Generation Asset Divestiture" above.

   Environmental Protection Measures

   The estimated expenditures of PG&E Corporation's subsidiaries for
environmental protection are subject to periodic review and revision to
reflect changing technology and evolving regulatory requirements. It is likely
that the stringency of environmental regulations will increase in the future.
As a result of the Utility's divestiture of most of its fossil-fueled power
plants and its geothermal generation facilities, the Utility's oxides of
nitrogen (NOx) emission reduction compliance costs have been reduced
significantly.

   Air Quality

   Pacific Gas and Electric Company's thermal electric generating plants are
subject to numerous air pollution control laws, including the California Clean
Air Act (CCAA) with respect to emissions. Pursuant to the CCAA and the Federal
Clean Air Act, two of the local air districts in which the Utility owns and
operates fossil-fueled generating plants have adopted final rules that require
a reduction in NOx emissions from the power plants of approximately 90% by
2004 (with numerous interim compliance deadlines).

   The Gas Accord authorizes $42 million to be included in rates through 2002,
for gas NOx retrofit projects related to natural gas compressor stations on
Pacific Gas and Electric Company's Line 300, which delivers gas from the
Southwest. Other air districts are considering NOx rules that would apply to
the Utility's other natural gas compressor stations in California. Eventually
the rules are likely to require NOx reductions of up to 80% at many of these
natural gas compressor stations. The Utility currently estimates that the
total cost of complying with these various NOx rules will be up to $51 million
over three years. Substantially all of these costs will be capital costs.

                                      34
<PAGE>

   PG&E Gen's compliance with certain future regulatory requirements limiting
the total amount of NOx emissions from its fossil-fueled power plants is
expected to be achieved through installation of additional controls, fuel
switching, and purchase of NOx allowances. USGenNE has agreed to be bound by a
number of state and regional initiatives that will require it to achieve
significant reductions of sulfur dioxide (SO\\2\\) and NOx emissions by the
time its older fossil-fueled power plants have been in operation for 40 years
or by 2010, whichever comes first. It is expected that USGenNE can meet these
requirements through utilization of allowances it currently owns, installation
of additional controls, or purchase of additional allowances. (SO\\2\\
allowances are emission credits that are traded in a national market under the
United States Environmental Protection Agency's (EPA) Acid Rain Program. NOx
allowances are emission credits that are traded in a regional market
consisting of seven Northeast states known as the Ozone Transport Region.) It
is estimated that USGenNE's total cost of complying with these requirements
will be up to $4 million through the year 2001.

   Water Quality

   Pacific Gas and Electric Company's existing power plants, including Diablo
Canyon, are subject to federal and state water quality standards with respect
to discharge constituents and thermal effluents. The Utility's fossil-fueled
power plants comply in all material respects with the discharge constituents
standards and either comply in all material respects with or are exempt from
the thermal standards. A thermal effects study at Diablo Canyon was completed
in May 1988, and was reviewed by the Central Coast Regional Water Quality
Control Board (Central Coast Board). The Central Coast Board did not make a
final decision on the report and requested that the Utility continue its
thermal effects monitoring program. In 1995, the Central Coast Board requested
that the Utility prepare an updated comprehensive assessment of Diablo
Canyon's thermal effects and approved a reduced environmental monitoring
program. A comprehensive statistical analysis of Diablo Canyon's thermal
effects was submitted to the Central Coast Board in December 1997 and a
regulatory assessment was submitted in November 1998. If the Central Coast
Board finds that Diablo Canyon's existing thermal limits are not protective of
beneficial uses of the marine waters, major modifications (e.g., cooling
towers) resulting in additional construction expenditures, or reduced power
operation, could be required.

   Pursuant to the federal Clean Water Act, the Utility is required to
demonstrate that the location, design, construction, and capacity of power
plant cooling water intake structures reflect the best technology available
(BTA) for minimizing adverse environmental impacts at its existing water-
cooled thermal plants. The Utility has submitted detailed studies of each
power plant's intake structure to various governmental agencies. Each plant's
existing water intake structure was found to meet the BTA requirements. The
Utility currently is completing a new study for Diablo Canyon. The study is
scheduled to be submitted to the Central Coast Board for review in 2000. If
the Central Coast Board finds that Diablo Canyon's cooling water intake
structure does not meet the BTA requirements, additional expenses for
construction or mitigation could be required. In addition, the promulgation or
modification of statutes, regulations, or water quality control plans at the
federal, state, or regional level may impose increasingly stringent cooling
water discharge requirements on the Utility's remaining power plants in the
future. Costs to comply with renewed permit conditions required to meet any
more stringent requirements that might be imposed cannot be estimated at the
present time.

   In December 1999, the Utility was notified by the purchaser of its former
Moss Landing power plant that that it had identified a cleaning procedure used
at the plant that released heated water from the intake, and that this
procedure is not specified in the plant's National Pollutant Discharge
Elimination System (NPDES) permit issued by the Central Coast Board. The
purchaser notified the Central Coast Board of its findings and the Central
Coast Board requested additional information from the purchaser. The Utility
has initiated an investigation of these activities during the time it owned
the plant. The Central Coast Board has been notified of the investigation and
the results will be presented to the Central Coast Board when the
investigation is complete. If the identified procedure was performed during
the Utility's ownership and was beyond the scope of the relevant NPDES
permits, the Central Coast Board may choose to initiate an enforcement action.
If so, the Utility could be subject to significant penalties. Until the
investigation is complete and the results discussed with the Central Coast
Board, it is not possible to determine whether the Utility will suffer a loss
in connection with this matter or to provide a more detailed estimate of such
liability.

                                      35
<PAGE>

   PG&E Gen's existing power plants, including USGenNE facilities, are subject
to federal and state water quality standards with respect to discharge
constituents and thermal effluents. Three of the fossil-fueled plants owned
and operated by USGenNE are operating in compliance with NPDES permits that
have expired. As to the facilities for which the NPDES permit has expired, new
permit applications are pending, and it is anticipated that all three
facilities will be able to continue to operate under existing terms and
conditions until new permits are issued. USGenNE has submitted a permit
renewal application and is negotiating with EPA on ongoing studies and permit
conditions. It is estimated that USGenNE's cost to comply with these
conditions could be as much as $5 million through the year 2001.

   Hazardous Waste Compliance and Remediation

   PG&E Corporation subsidiaries assess, on an ongoing basis, measures that
may need to be taken to comply with laws and regulations related to hazardous
materials and hazardous waste compliance and remediation activities. The
Utility has a comprehensive program to comply with many hazardous waste
storage, handling, and disposal requirements promulgated by the EPA under the
Resource Conservation and Recovery Act (RCRA) and the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA), along with
other state hazardous waste laws and other environmental requirements.

   One part of this program is aimed at assessing whether and to what extent
remedial action may be necessary to mitigate potential hazards posed by
certain disposal sites and retired manufactured gas plant sites. During their
operation, manufactured gas plants produced lampblack and tar residues,
byproducts of a process that Pacific Gas and Electric Company, its predecessor
companies, and other utilities used as early as the 1850s to manufacture gas
from coal and oil. As natural gas became widely available (beginning about
1930), the Utility's manufactured gas plants were removed from service. The
residues that may remain at some sites contain chemical compounds that now are
classified as hazardous. The Utility has identified and reported to federal
and California environmental agencies 96 manufactured gas plant sites that
operated in the Utility's service territory. The Utility owns all or a portion
of 29 of these manufactured gas plant sites. The Utility has a program, in
cooperation with environmental agencies, to evaluate and take appropriate
action to mitigate any potential health or environmental hazards at sites that
the Utility owns. It is estimated that the Utility's program may result in
expenditures of approximately $5 million in 2000. The full long-term costs of
the program cannot be determined accurately until a closer study of each site
has been completed. It is expected that expenses will increase as remedial
actions related to these sites are approved by regulatory agencies or if the
Utility is found to be responsible for cleanup at sites it currently does not
own.

   In addition to the manufactured gas plant sites, the Utility may be
required to take remedial action at certain other disposal sites if they are
determined to present a significant threat to human health and the environment
because of an actual or potential release of hazardous substances. The Utility
has been designated as a potentially responsible party (PRP) under CERCLA (the
federal Superfund law) with respect to the PRC Patterson site in Patterson,
California, and the Industrial Waste Processing site near Fresno, California.
With respect to the Casmalia site near Santa Maria, California, the Utility
and several other generators of waste sent to the site have entered into a
court-approved agreement with the EPA that requires these generators to
perform certain site investigation and mitigation measures, and provides a
release from liability for certain other site cleanup obligations. Although
the Utility has not been formally designated a PRP with respect to the
Geothermal Incorporated site in Lake County, California, the Central Valley
Regional Water Quality Control Board and the California Attorney General's
office have directed the Utility and other parties to initiate measures with
respect to the study and remediation of that site.

   In addition, Pacific Gas and Electric Company has been named as a defendant
in several civil lawsuits in which plaintiffs allege that the Utility is
responsible for performing or paying for remedial action at sites the Utility
no longer owns or never owned.

   The cost of hazardous substance remediation ultimately undertaken by
Pacific Gas and Electric Company is difficult to estimate. It is reasonably
possible that a change in the estimate may occur in the near term due to

                                      36
<PAGE>

uncertainty concerning the Utility's responsibility, the complexity of
environmental laws and regulations, and the selection of compliance
alternatives. At December 31, 1999, the Utility expects to spend $300 million
for hazardous waste remediation costs at identified sites, including divested
fossil-fueled power plants, where such costs are probable and quantifiable.
(Although the Utility has sold most of its fossil-fueled power plants, the
Utility has retained pre-closing environmental liability with respect to these
plants.) The Utility had an accrued liability of $271 million at December 31,
1999, representing the discounted value of these costs. Environmental
remediation at identified sites may be as much as $486 million if, among other
things, other PRPs are not financially able to contribute to these costs or
further investigation indicates that the extent of contamination or necessary
remediation is greater than anticipated at sites for which the Utility is
responsible. The Utility estimated the upper limit of the range of costs using
assumptions least favorable to the Utility based upon a range of reasonably
possible outcomes. Costs may be higher if the Utility is found to be
responsible for cleanup costs at additional sites or identifiable possible
outcomes change.

   PG&E Gen acquired the onsite environmental liability associated with
USGenNE's acquisition of electric generating facilities from NEES, but did not
acquire any offsite liability associated with the past disposal practices at
the acquired facilities. PG&E Gen has obtained pollution liability and
environmental remediation insurance coverage to limit the financial risk
associated with the onsite pollution liability at all of its facilities.

   Potential Recovery of Hazardous Waste Compliance and Remediation Costs

   In 1994, the CPUC established a ratemaking mechanism for hazardous waste
remediation costs (HWRC). That mechanism assigns 90% of the includable
hazardous substance cleanup costs to utility ratepayers and 10% to utility
shareholders, without a reasonableness review of such costs or of underlying
activities. Under the HWRC mechanism, 70% of the ratepayer portion of Pacific
Gas and Electric Company's cleanup costs is attributed to its gas department
and 30% is attributed to its electric department. Insurance recoveries are
assigned 70% to shareholders and 30% to ratepayers until both are reimbursed
for the costs of pursuing insurance recoveries. The balance of insurance
recoveries are allocated 90% to shareholders and 10% to ratepayers until
shareholders are reimbursed for their 10% share of cleanup costs. Any
unallocated funds remaining are held for five years and then distributed 60%
to ratepayers and 40% to shareholders over the next five years. The Utility
can seek to recover hazardous substance cleanup costs under the HWRC in the
rate proceeding it deems most appropriate. In connection with electric
industry restructuring, the HWRC mechanism may no longer be used to recover
electric generation-related cleanup costs for contamination caused by events
occurring after January 1, 1998.

   For each divested generation facility where the Utility retained
environmental remediation liabilities, the plant's decommissioning cost
estimate was adjusted by the Utility's estimated forecast of environmental
remediation costs. (The buyers assumed the non-environmental decommissioning
liability for these plants.) The CPUC ordered that excess recoveries of
environmental and non-environmental decommissioning accruals related to the
divested plants be used to offset other transition costs. As of December 31,
1999, the Utility has recovered from ratepayers approximately $114 million for
environmental decommissioning accrual related to the divested plants. This
amount will earn interest at 3% per year that will be used to meet the future
environmental remediation costs for the divested plants. The net
decommissioning accruals recovered from ratepayers attributable to the non-
environmental liability for the divested plants was approximately $53 million.
Because the Utility no longer has this non-environmental decommissioning
liability, it has used this excess recovery amount to reduce other transition
costs.

   Of the $271 million accrued liability, discussed above, the Utility has
recovered $148 million through rates, including $34 million through
depreciation, and expects to recover $95 million in future rates.
Additionally, the Utility is mitigating its costs by seeking recovery of its
costs from insurance carriers and from other third parties as appropriate.

   In 1992, Pacific Gas and Electric Company filed a complaint in San
Francisco County Superior Court against more than 100 of its domestic and
foreign insurers, seeking damages and declaratory relief for remediation and
other costs associated with hazardous waste mitigation. The Utility previously
had notified its insurance carriers

                                      37
<PAGE>

that it seeks coverage under its comprehensive general liability policies to
recover costs incurred at certain specified sites. In general, the Utility's
carriers neither admitted nor denied coverage, but requested additional
information from the Utility. Although the Utility has received some amounts
in settlements with certain of its insurers (approximately $71 million through
December 31, 1999), the ultimate amount of recovery from insurance coverage,
either in the aggregate or with respect to a particular site, cannot be
quantified at this time.

   Compressor Station Litigation

   Several cases have been brought against Pacific Gas and Electric Company
seeking damages from alleged chromium contamination at the Utility's Hinkley,
Topock, and Kettleman Compressor Stations. See Item 3, "Legal Proceedings--
Compressor Station Chromium Litigation" below, for a description of the
pending litigation.

   Electric and Magnetic Fields

   In January 1991, the CPUC opened an investigation into potential interim
policy actions to address increasing public concern, especially with respect
to schools, regarding potential health risks that may be associated with
electric and magnetic fields (EMF) from utility facilities. In its order
instituting the investigation, the CPUC acknowledged that the scientific
community has not reached consensus on the nature of any health impacts from
contact with EMF, but went on to state that a body of evidence has been
compiled that raises the question of whether adverse health impacts might
exist.

   In November 1993, the CPUC adopted an interim EMF policy for California
energy utilities that, among other things, requires California energy
utilities to take no-cost and low-cost steps to reduce EMF from new and
upgraded utility facilities. California energy utilities are required to fund
a $1.5 million EMF education program and a $5.6 million EMF research program
managed by the California Department of Health Services. It is expected that
the CPUC and the California Department of Health Services will complete its
EMF research program by December 2001.

   As part of its effort to educate the public about EMF, Pacific Gas and
Electric Company provides interested customers with information regarding the
EMF exposure issue. The Utility also provides a free field measurement service
to inform customers about EMF levels at different locations in and around
their residences or commercial buildings.

   The Utility currently is not involved in third party litigation concerning
EMF. In August 1996, the California Supreme Court held that homeowners are
barred from suing utilities for alleged property value losses caused by fear
of EMF from power lines. The Court expressly limited its holding to property
value issues, leaving open the question as to whether lawsuits for alleged
personal injury resulting from exposure to EMF are similarly barred. The
Utility was a defendant in civil litigation in which plaintiffs alleged
personal injuries resulting from exposure to EMF. In January 1998, the appeals
court in this matter held that the CPUC has exclusive jurisdiction over
personal injury and wrongful death claims arising from allegations of harmful
exposure to EMF and barred plaintiffs' personal injury claims. Plaintiffs
filed an appeal of this decision with the California Supreme Court. The
California Supreme Court declined to hear the case.

   If the scientific community reaches a consensus that EMF presents a health
hazard and further determines that the impact of utility-related EMF exposures
can be isolated from other exposures, the Utility may be required to take
mitigation measures at its facilities. The costs of such mitigation measures
cannot be estimated with any certainty at this time. However, such costs could
be significant, depending on the particular mitigation measures undertaken,
especially if relocation of existing power lines ultimately is required.

   Low Emission Vehicle Programs

   In December 1995, the CPUC issued its decision in the Low Emission Vehicle
(LEV) proceeding, which approved approximately $42 million in funding for
Pacific Gas and Electric Company's LEV program for the

                                      38
<PAGE>

six-year period beginning in 1996. The CPUC's decision on electric industry
restructuring found that the costs of utility LEV programs should continue to
be collected by the utility for the duration of the six-year period. The
Utility continues to run its LEV program as funded.

ITEM 2. Properties.

   Information concerning Pacific Gas and Electric Company's electric
generation units, electric and gas transmission facilities, and electric and
gas distribution facilities is included in response to Item 1. All of the
Utility's real properties and substantially all of the Utility's personal
properties are subject to the lien of an indenture that provides security to
the holders of the Utility's First and Refunding Mortgage Bonds.

   Information concerning properties and facilities owned by other PG&E
Corporation subsidiaries is included in the discussion under the heading of
this report entitled "National Energy Group."

ITEM 3. Legal Proceedings.

   See Item 1, Business, for other proceedings pending before governmental and
administrative bodies. In addition to the following legal proceedings, PG&E
Corporation and Pacific Gas and Electric Company are subject to routine
litigation incidental to their business.

Compressor Station Chromium Litigation

   Pacific Gas and Electric Company is currently a defendant in three civil
actions pending in California courts. These cases are (1) Aguayo v. Pacific
Gas and Electric Company, filed March 15, 1995, in Los Angeles County Superior
Court, (2) Aguilar v. Pacific Gas and Electric Company, filed October 4, 1996,
in Los Angeles County Superior Court, and (3) Acosta, et al. v. Betz
Laboratories, Inc., Pacific Gas and Electric Company, et al., filed November
27, 1996, in Los Angeles County Superior Court. These cases are collectively
referred to as the "Aguayo Litigation." There are approximately 900 plaintiffs
in the Aguayo Litigation.

   Each of the complaints in the Aguayo Litigation alleges personal injuries
and seeks compensatory and punitive damages in an unspecified amount arising
out of alleged exposure to chromium contamination in the vicinity of the
Utility's gas compressor stations at Kettleman, Hinkley, and Topock,
California. The plaintiffs in the Aguayo Litigation include current and former
Utility employees, relatives of current and former employees, residents in the
vicinity of the compressor stations, and persons who visited the gas
compressor stations. The plaintiffs also include spouses or children of these
plaintiffs who claim loss of consortium or wrongful death.

   All discovery and discovery motion practice in the Aguayo Litigation have
been referred by the judge to a discovery referee. The discovery referee has
set the procedures for selecting 18 trial test plaintiffs and two alternates
in the Aguayo Litigation. Ten of these trial test plaintiffs were selected by
plaintiffs, seven trial test plaintiffs were selected by defendants, and one
trial test plaintiff and two alternates were selected at random. The trial
date has been set for November 17, 2000 in Los Angeles Superior Court.

   The Utility is responding to the complaints and asserting affirmative
defenses. The Utility will pursue appropriate legal defenses, including
statute of limitations or exclusivity of workers' compensation laws, and
factual defenses including lack of exposure to chromium and the inability of
chromium to cause certain of the illnesses alleged. At this stage of the
proceedings, there is substantial uncertainty concerning the claims alleged.
The Utility is attempting to gather information concerning the alleged type
and duration of exposure, the nature of injuries alleged by individual
plaintiffs, and the additional facts necessary to support its legal defenses,
in order to better evaluate and defend this litigation.

   PG&E Corporation believes that the ultimate outcome of this matter will not
have a material adverse impact on its or Pacific Gas and Electric Company's
financial position or results of operations.

Texas Franchise Fee Litigation

   On July 31, 1997, PG&E Corporation acquired Valero Energy Corporation
(Valero), now known as PG&E Gas Transmission, Texas Corporation. PG&E Gas
Transmission, Texas Corporation and its affiliates (PG&E GTT) succeeded to the
cases described below, which were pending at the time of the acquisition
against Valero and its affiliates. A lawsuit was also pending at such time
that had been filed by the City of Pharr, but no PG&E GTT entity has been
served in this case. These cases are collectively referred to as the "Texas
Franchise Fees Litigation." These actions were brought by various cities in
Texas arising out of several Texas statutes and city ordinances involving the
following: (a) what rights, if any, Texas cities may have to require companies
engaged in the gathering, production, distribution, transmission, and/or sale
of natural gas to obtain consent from, and pay fees to, the cities within
which such activities are being conducted, (b) what form any such consent, if
required, must take, (c) what constitutes "use" of city property, and (d) what
types of charges, if any, a Texas city properly can assess against gas
pipeline and marketing companies for use of that city's property.

L.P. (now known as PG&E Texas Pipeline, L.P.), and Reata Industrial Gas, L.P.
(now known as PG&E Reata Energy, L.P.), Southern Union Gas Co., and Mercado

Hidalgo County, Texas, (5) City of La Joya v. RGVG, Valero Energy Corporation
(now known as PG&E GTT), Southern Union Company, et al., filed December 27,
1996, in the 92nd State District Court, Hidalgo County, Texas, (6) Cities of
San Juan, La Villa, Penitas, Edcouch, and Palmview v. RGVG, Valero Energy
Corporation (now known as PG&E Gas Transmission, Texas Corporation), Southern
Union Company, et al., filed December 27, 1996, in the 93rd State District

Company (now known as PG&E Texas Natural Gas Company), Valero Gas Marketing
Co. (now known as PG&E Energy Trading Holdings Corporation), and Reata
Industrial Gas, L.P. (now known as PG&E Reata Energy L.P.) filed April 17,
1997, in the 92nd State District Court, Hidalgo County, Texas. The lawsuits
involving the City of La Joya (item number 5 above) and the Cities of San
Juan, La Villa, Penitas, Edcouch, and Palmview (item number 6 above) were
voluntarily dismissed on July 13, 1999, and February 23, 2000, respectively.
However, all of these cities are class members in the San Benito class action
(item number 5 above) as are the Cities of Alton and Donna.

   The trial in the City of Edinburg case began on June 15, 1998. On August
14, 1998, a jury returned a verdict in favor of the City of Edinburg, and
awarded damages in the approximate aggregate amount of $9.8 million, plus
attorneys' fees of approximately $3.5 million, against PG&E GTT, Southern
Union and various affiliates of PG&E GTT and Southern Union. The jury refused
to award punitive damages against the PG&E GTT defendants. On December 1,
1998, based on the jury verdict, the court entered a judgment in the City's
favor, and awarded damages of $5.3 million, attorneys' fees of up to $3.5
million (to the extent that the City is successful on appeal), prejudgment
interest of $1.6 million, and post-judgment interest at the rate of 10% per
year, compounded annually, from December 1, 1998. The court found that various
PG&E GTT and Southern

                                      40
<PAGE>

Union defendants were jointly and severally liable for $3.3 million of the
damages, prejudgment interest in the amount of $1.1 million, and all the
attorneys' fees. Certain PG&E GTT subsidiaries were found solely liable for
$1.4 million of the damages and prejudgment interest of $440,000. The court
did not clearly indicate the extent to which the PG&E GTT defendants could be
found liable for the remaining damages. The judgment also decreed that (1)
certain pipelines owned by PG&E Texas Pipeline, L.P. (formerly known as Valero
Transmission, L.P.) encroached on the City's property without the City's
consent and (2) based on certain jury findings, PG&E GTT was vicariously
liable for certain conduct of the local distribution company, RGVG, from
October 1, 1985, to September 30, 1993 (the date Valero, PG&E GTT's
predecessor, sold RGVG to Southern Union). The PG&E GTT defendants are
appealing the judgment.

   On November 4, 1997, the lawsuit filed in Cameron County, Texas, by the
cities of San Benito, Primera, and Port Isabel was amended to name as
defendants PG&E GTT and all of its subsidiaries (excluding its Canadian gas
trading and power trading subsidiaries), PG&E Gas Transmission Teco, Inc. and
its subsidiaries, and PG&E Energy Trading Corporation (now known as PG&E
Energy Trading--Gas Corporation) (collectively these defendants are referred
to as the "PG&E Corporation Texas defendants"). In November 1997, the court
ordered a state-wide class certified and granted plaintiffs' request to
dismiss RGVG and the Southern Union defendants. In connection with the
certification of a class in this case, the court ordered notice to be sent to
all potential class members and setting an opt-out deadline of December 31,
1997. Notices were mailed to approximately 159 Texas cities. Fewer than 20
cities opted out by the deadline. Some of the cities opting out include
Austin, Brownsville, Houston, and San Antonio. The city of Los Indios has been
severed from the class and its claims separately docketed in Cameron County,
Texas. On November 22, 1999, the court signed an order dismissing from the
class 42 cities because it determined there was no pipeline presence and no
past or present sales activity in such cities, leaving 106 cities in the
class. The parties are negotiating the terms of a final settlement agreement.
The settlement proposal contemplates, among other things, that the PG&E
Corporation Texas defendants would pay a total of not more than $12.2 million
to the settling class cities, inclusive of attorney fees and expenses, which
amount may be reduced by amounts attributable to certain opt-out cities. The
defendants retain the right to reject the settlement if the settlement
proposal is not approved by certain key cities and by 80% of the overall
plaintiff class. Although a significant number of the 106 cities in the
plaintiff class already have either approved the settlement by enacting the
consent ordinance or have adopted resolutions to pass the ordinance, certain
key cities have not yet approved the settlement. The settlement is also
subject to final court approval. On January 27, 2000, the court approved the
settlement proposal and established a 14-day period for the cities to decide
whether to accept the negotiated settlement terms or opt out of the
settlement. The court also stated that if the City of Corpus Christi does not
accept the settlement proposal, it will be placed in a single city sub-class
and its claims will not be finalized as part of the settlement approval.
Corpus Christi has the right to opt out of this subclass. Although the 14-day
period expired on February 11, 2000, certain cities have requested and
received additional time to decide whether to opt out.

   In July 1996, the lawsuits originally filed by the cities of Alton and
Donna as intervening actions in the City of Edinburg case were severed from
the Edinburg lawsuit. The claims asserted by the cities of Alton and Donna are
substantially similar to the San Benito litigation claims, except that no
class claims are asserted. Damages are not quantified. Defendants' motion to
transfer venue of both cases to Bexar County, Texas, is currently pending. The
Cities of Alton and Donna are also members of the San Benito class, and will
be required to dismiss their claims against PG&E GTT in this separate lawsuit
if they agree to accept the settlement of the San Benito class action.

   On September 4, 1997, the City of Mercedes amended its petition to include
class action claims and requested to be named as class representative for a
statewide class consisting of all Texas municipal corporations,
municipalities, towns, and villages, excluding the cities of Edinburg and
Weslaco (both of which have filed separate actions), in which any of the
defendants have sold or supplied gas, or used public rights-of-way to
transport gas. The City of Mercedes has requested a damage award, but has not
specified an amount. On November 26, 1997, defendants' motion to recuse the
presiding judge was granted. Plaintiffs' request for class certification is
still pending.


                                      41
<PAGE>

   The causes of action alleged in the case brought by the City of Weslaco are
identical to those alleged in the City of Mercedes case, except that no class
claims are asserted. Damages are not quantified. A motion similar to the
motion filed in Mercedes, seeking to recuse the judge of the 92nd State
District Court, was filed but not ruled upon. On May 12, 1999, this case was
transferred to the 370th State District Court of Hidalgo County, Texas.
Defendants' motion to transfer venue to Bexar County, Texas, is currently
pending.

   In addition to the cases described above, during May 1996, a petition in
intervention was filed in the Edinburg case by the City of Pharr. On June 24,
1996, the court severed Pharr from the Edinburg case, certified the severed
case as a class action against Southern Union Company and RGVG, and named
Pharr as class representative for a class consisting of those Texas cities,
excluding Edinburg and McAllen, that have or had natural gas franchise
agreements with RGVG or Southern Union. The Pharr class was certified as to
two claims: breach of contract and declaratory relief dealing with the rights,
status, and legal relationship between plaintiff, the class members, and the
local distribution company regarding payment of franchise fees and use of
granted easements. Plaintiffs' original petition also sought injunctive
relief, but the class order does not include injunctive relief. Plaintiffs
seek actual damages, exemplary damages, attorneys' fees, costs, and pre- and
post-judgment interest, but have not specified any amounts. On January 26,
1998, the court added the Cities of Mercedes and Weslaco as class
representatives. None of the PG&E Corporation Texas entities have ever been
served in the Pharr litigation. On December 30, 1997, in affirming the Pharr
class certification, the appellate court specifically found that the PG&E GTT
entities were not parties to the Pharr class action. However, the same 29 PG&E
Corporation Texas entities that are class defendants in the San Benito
litigation have subsequently been named and served as defendants in two
ancillary suits brought during 1998 by the Pharr class plaintiffs. These
ancillary suits seek only injunctive relief, for the stated purpose of
"protecting" the Pharr class from alleged interference by the San Benito
class.

   PG&E Corporation believes that the ultimate outcome of this matter will not
have a material adverse impact on its financial position or results of
operations. As discussed above under "Item 1--National Energy Group-- Gas
Transmission Operations," in January 2000, PG&E Corporation's National Energy
Group signed a definitive agreement to sell the stock of PG&E Gas
Transmission, Texas Corporation and PG&E Gas Transmission Teco, Inc., the
National Energy Group subsidiaries which conduct gas transmission operations
in Texas. The buyer will assume all liabilities associated with the cases
described above.

the purpose of forming an opinion on those statements taken as a whole. The
schedules listed in Part IV, Item 14. (a)(5) in this Form 10-K are the
responsibility of the management of PG&E Corporation and of Pacific Gas and
Electric Company and are presented for purposes of complying with the
Securities and Exchange Commission's rules and are not part of the
consolidated financial statements. These schedules have been subjected to the
auditing procedures applied in the audits of the consolidated financial

the two years in the period ended December 31, 1998 included in the PG&E
Corporation and Pacific Gas and Electric Company Annual Report to Shareholders
incorporated by reference in this Form 10-K, and have issued our report

each of PG&E Corporation and Pacific Gas and Electric Company for the Years
Ended December 31, 1998 and 1997, are the responsibility of the management of

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and the Board of Directors of PG&E Corporation and Pacific
Gas and Electric Company:

   We have audited the accompanying consolidated balance sheets of PG&E
Corporation (a California corporation) and subsidiaries and Pacific Gas and
Electric Company (a California corporation) and subsidiaries as of December
31, 1998, and the related statements of consolidated income, cash flows, and
common stock equity of PG&E Corporation and subsidiaries and the related
statements of consolidated income, cash flows and stockholders' equity of
Pacific Gas and Electric Company and subsidiaries for each of the two years in
the period ended December 31, 1998. These financial statements are the
responsibility of the management of PG&E Corporation and Pacific Gas and
Electric Company. Our responsibility is to express an opinion on these
financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial positions of PG&E Corporation and
subsidiaries, and of Pacific Gas and Electric Company and subsidiaries, as of
December 31, 1998, and the results of their operations and their cash flows
for each of the two years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.

                               PG&E Corporation

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


                                  Article I.
                                 SHAREHOLDERS.


     1.   Place of Meeting.  All meetings of the shareholders shall be held at
the office of the Corporation in the City and County of San Francisco, State of
California, or at such other place, within or without the State of California,
as may be designated by the Board of Directors.

     2.   Annual Meetings.  The annual meeting of shareholders shall be held
each year on a date and at a time designated by the Board of Directors.

     Written notice of the annual meeting shall be given not less than ten (or,
if sent by third-class mail, thirty) nor more than sixty days prior to the date
of the meeting to each shareholder entitled to vote thereat.  The notice shall
state the place, day, and hour of such meeting, and those matters which the
Board, at the time of mailing, intends to present for action by the
shareholders.

     Notice of any meeting of the shareholders shall be given by mail or
telegraphic or other written communication, postage prepaid, to each holder of
record of the stock entitled to vote thereat, at his address, as it appears on
the books of the Corporation.

     At an annual meeting of shareholders, only such business shall be conducted
as shall have been properly brought before the annual meeting. To be properly
brought before an annual meeting, business must be (i) specified in the notice
of the annual meeting (or any supplement thereto) given by or at the direction
of the Board, or (ii) otherwise properly brought before the annual meeting by a
shareholder. For business to be properly brought before an annual meeting by a
shareholder, including the nomination of any person (other than a person
nominated by or at the direction of the Board) for election to the Board, the
shareholder must have given timely and proper written notice to the Corporate
Secretary of the Corporation. To be timely, the shareholder's written notice
must be received at the principal executive office of the Corporation not less
than forty-five days before the date corresponding to the mailing date of the
notice and proxy materials for the prior year's annual meeting of shareholders;
provided, however, that if the annual meeting to which the shareholder's written
notice relates is to be held on a date that differs by more than thirty days
from the date of the last annual meeting of shareholders, the shareholder's
written notice to
<PAGE>

be timely must be so received not later than the close of business on the tenth
day following the date on which public disclosure of the date of the annual
meeting is made or given to shareholders. To be proper, the shareholder's
written notice must set forth as to each matter the shareholder proposes to
bring before the annual meeting (a) a brief description of the business desired
to be brought before the annual meeting, (b) the name and address of the
shareholder as they appear on the Corporation's books, (c) the class and number
of shares of the Corporation that are beneficially owned by the shareholder, and
(d) any material interest of the shareholder in such business. In addition, if
the shareholder's written notice relates to the nomination at the annual meeting
of any person for election to the Board, such notice to be proper must also set
forth (a) the name, age, business address, and residence address of each person
to be so nominated, (b) the principal occupation or employment of each such
person, (c) the number of shares of capital stock of the Corporation
beneficially owned by each such person, and (d) such other information
concerning each such person as would be required under the rules of the
Securities and Exchange Commission in a proxy statement soliciting proxies for
the election of such person as a Director, and must be accompanied by a consent,
signed by each such person, to serve as a Director of the Corporation if
elected. Notwithstanding anything in the Bylaws to the contrary, no business
shall be conducted at an annual meeting except in accordance with the procedures
set forth in this Section.

     3.   Special Meetings.  Special meetings of the shareholders shall be
called by the Corporate Secretary or an Assistant Corporate Secretary at any
time on order of the Board of Directors, the Chairman of the Board, the Vice
Chairman of the Board, the Chairman of the Executive Committee, or the
President. Special meetings of the shareholders shall also be called by the
Corporate Secretary or an Assistant Corporate Secretary upon the written request
of holders of shares entitled to cast not less than ten percent of the votes at
the meeting. Such request shall state the purposes of the meeting, and shall be
delivered to the Chairman of the Board, the Vice Chairman of the Board, the
Chairman of the Executive Committee, the President, or the Corporate Secretary.

     A special meeting so requested shall be held on the date requested, but not
less than thirty-five nor more than sixty days after the date of the original
request. Written notice of each special meeting of shareholders, stating the
place, day, and hour of such meeting and the business proposed to be transacted
thereat, shall be given in the manner stipulated in Article I, Section 2,
Paragraph 3 of these Bylaws within twenty days after receipt of the written
request.

     4.   Attendance at Meetings.  At any meeting of the shareholders, each
holder of record of stock entitled to vote thereat may attend in person or may
designate an agent or a reasonable number of agents, not to exceed three to
attend the meeting and cast votes for his or her shares. The authority of agents
must be evidenced by a written proxy signed by the shareholder designating the
agents authorized to attend the meeting and be delivered to the Corporate
Secretary of the Corporation prior to the commencement of the meeting.

                                       2

     5.   Shareholder Action by Written Consent.  Subject to Section 603 of the
California Corporations Code, any action which, under any provision of the
California Corporations Code, may be taken at any annual or special meeting of
shareholders may be taken without a meeting and without prior notice if a
consent in writing, setting forth the action so taken, shall be signed by the
holders of outstanding shares having not less than the minimum number of votes
that would be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted.

     Any party seeking to solicit written consent from shareholders to take
corporate action must deliver a notice to the Corporate Secretary of the
Corporation which requests the Board of Directors to set a record date for
determining shareholders entitled to give such consent. Such written request
must set forth as to each matter the party proposes for shareholder action by
written consents (a) a brief description of the matter and (b) the class and
number of shares of the Corporation that are beneficially owned by the
requesting party. Within ten days of receiving the request in the proper form,
the Board shall set a record date for the taking of such action by written
consent in accordance with California Corporations Code Section 701 and Article
IV, Section 1 of these Bylaws. If the Board fails to set a record date within
such ten-day period, the record date for determining shareholders entitled to
give the written consent for the matters specified in the notice shall be the
day on which the first written consent is given in accordance with California
Corporations Code Section 701.

     Each written consent delivered to the Corporation must set forth (a) the
action sought to be taken, (b) the name and address of the shareholder as they
appear on the Corporation's books, (c) the class and number of shares of the
Corporation that are beneficially owned by the shareholder, (d) the name and
address of the proxyholder authorized by the shareholder to give such written
consent, if applicable, and (d) any material interest of the shareholder or
proxyholder in the action sought to be taken.

     Consents to corporate action shall be valid for a maximum of sixty days
after the date of the earliest dated consent delivered to the Corporation.
Consents may be revoked by written notice (i) to the Corporation, (ii) to the
shareholder or shareholders soliciting consents or soliciting revocations in
opposition to action by consent proposed by the Corporation (the "Soliciting
Shareholders"), or (iii) to a proxy solicitor or other agent designated by the
Corporation or the Soliciting Shareholders.

     Within three business days after receipt of the earliest dated consent
solicited by the Soliciting Shareholders and delivered to the Corporation in the
manner provided in California Corporations Code Section 603 or the determination
by the Board of Directors of the Corporation that the Corporation should seek
corporate action by written consent, as the case may be, the Corporate Secretary
shall engage nationally recognized independent inspectors of elections for the
purpose of performing a ministerial review of the validity of the consents and
revocations. The cost of retaining inspectors of election shall be borne by the
Corporation.

                                       3
<PAGE>

     Consents and revocations shall be delivered to the inspectors upon receipt
by the Corporation, the Soliciting Shareholders or their proxy solicitors, or
other designated agents. As soon as consents and revocations are received, the
inspectors shall review the consents and revocations and shall maintain a count
of the number of valid and unrevoked consents. The inspectors shall keep such
count confidential and shall not reveal the count to the Corporation, the
Soliciting Shareholder or their representatives, or any other entity. As soon as
practicable after the earlier of (i) sixty days after the date of the earliest
dated consent delivered to the Corporation in the manner provided in California
Corporations Code Section 603, or (ii) a written request therefor by the
Corporation or the Soliciting Shareholders (whichever is soliciting consents),
notice of which request shall be given to the party opposing the solicitation of
consents, if any, which request shall state that the Corporation or Soliciting
Shareholders, as the case may be, have a good faith belief that the requisite
number of valid and unrevoked consents to authorize or take the action specified
in the consents has been received in accordance with these Bylaws, the
inspectors shall issue a preliminary report to the Corporation and the
Soliciting Shareholders stating: (a) the number of valid consents, (b) the
number of valid revocations, (c) the number of valid and unrevoked consents, (d)
the number of invalid consents, (e) the number of invalid revocations, and (f)
whether, based on their preliminary count, the requisite number of valid and
unrevoked consents has been obtained to authorize or take the action specified
in the consents.

     Unless the Corporation and the Soliciting Shareholders shall agree to a
shorter or longer period, the Corporation and the Soliciting Shareholders shall
have forty-eight hours to review the consents and revocations and to advise the
inspectors and the opposing party in writing as to whether they intend to
challenge the preliminary report of the inspectors. If no written notice of an
intention to challenge the preliminary report is received within forty-eight
hours after the inspectors' issuance of the preliminary report, the inspectors
shall issue to the Corporation and the Soliciting Shareholders their final
report containing the information from the inspectors' determination with
respect to whether the requisite number of valid and unrevoked consents was
obtained to authorize and take the action specified in the consents. If the
Corporation or the Soliciting Shareholders issue written notice of an intention
to challenge the inspectors' preliminary report within forty-eight hours after
the issuance of that report, a challenge session shall be scheduled by the
inspectors as promptly as practicable. A transcript of the challenge session
shall be recorded by a certified court reporter. Following completion of the
challenge session, the inspectors shall as promptly as practicable issue their
final report to the Soliciting Shareholders and the Corporation, which report
shall contain the information included in the preliminary report, plus all
changes in the vote totals as a result of the challenge and a certification of
whether the requisite number of valid and unrevoked consents was obtained to
authorize or take the action specified in the consents. A copy of the final
report of the inspectors shall be included in the book in which the proceedings
of meetings of shareholders are recorded.

     Unless the consent of all shareholders entitled to vote have been solicited
in writing, the Corporation shall give prompt notice to the shareholders in
accordance with

                                       4
<PAGE>

California Corporations Code Section 603 of the results of any consent
solicitation or the taking of the corporate action without a meeting and by less
than unanimous written consent.

of the Corporation and contained in the notice of any such meeting. Notice of

     6.   Quorum.  A quorum for the transaction of business at any meeting of
the Board of Directors shall consist of six members.

     7.   Action by Consent.  Any action required or permitted to be taken by
the Board of Directors may be taken without a meeting if all Directors
individually or collectively consent in writing to such action. Such written
consent or consents shall be filed with the minutes of the proceedings of the
Board of Directors.

     8.   Meetings by Conference Telephone.  Any meeting, regular or special, of
the Board of Directors or of any committee of the Board of Directors, may be
held by conference telephone or similar communication equipment, provided that
all Directors participating in the meeting can hear one another.

                                 Article III.

Company is in breach or violation of, or default under, any of the Scheduled

     4.14 Employee Plans and Labor Matters.
          --------------------------------

                      -------------
such Company Employee Plan, (iii) the most recent IRS Form 5500 for such Company
Employee Plans, and (iv) the most recent determination letter issued by the IRS
with respect to any Company Employee Plan intended to be qualified under Section
401(a) of the Code.

     (b)  ERISA.  (i) None of the ERISA Plans, is a "multiemployer pension
          -----
plan," as described in Section 3(37) of ERISA, or a "multiple employer pension
plan," as defined in Section 4063 of ERISA, and (ii) no material liability under
Title IV of ERISA has been incurred by the Acquired Companies or any ERISA Plan
that has not been satisfied in full, other than liability for premiums that are
not yet due and payable to the Pension Benefit Guaranty Corporation, and there
exist no facts or circumstances which could be expected to result in such
liability. No plan has an "accumulated funding deficiency" (within the meaning
of Section 302 of ERISA and Section 412 of the Code). Full payment has been
made, or will be made in accordance with Section 404(a)(6) of the Code, of all
amounts which any Acquired Company is required to pay under the terms of each of
the Company Employee Plans and Section 412 of the Code, and all such amounts

<PAGE>

Section 401(a) of the Code has received a favorable determination letter from
the IRS to the effect that it is so qualified, and to the Seller's knowledge,
nothing has occurred since the date of such letter to adversely affect the
qualified status of each such plan. Except as set forth on Schedule 4.14, none
                                                           -------------
of the Company Employee Plans or any other plan, program, or arrangement of the
Acquired Companies would result, separately or in the aggregate, in the payment
of any "excess parachute payment" within the meaning of Section 280G of the
Code. Each Company Employee Plan has been operated in all material aspects in
accordance with its terms and the requirements of Applicable Law. To the
knowledge of Seller, there have been no non-exempt "prohibited transactions"

          ----------                          -------------
of the transactions contemplated by this Agreement will not (whether alone or
upon the occurrence of any other event) (i) entitle any current or former

selling, and will not offer or sell, for Seller in connection with any
distribution of the Shares, and Buyer does not have a participation and will not
participate in any such undertaking or in any underwriting of such an
undertaking except in compliance with applicable federal and state securities

economic risk of its investment in the Shares, and has such knowledge and
experience in financial and business matters that it is capable of evaluating
the merits and risks of an investment in the Shares.  Buyer is an "accredited
investor" as such term is defined in Regulation D under the Securities Act.
Buyer understands that the Shares will not have been registered pursuant to the

under such laws and applicable regulations the Shares cannot be sold or
otherwise disposed of without registration under the Securities Act or an
exemption therefrom.

finder on account of this Agreement or the transactions contemplated hereby for
which Seller or its Affiliates will have any responsibility or liability.

     5.9  Independent Investigation.  Buyer hereby acknowledges and affirms
          -------------------------
that it has completed its own independent investigation, analysis and evaluation
of the Acquired Companies, that it has made all such reviews and inspections of
the business, assets, results of operations, condition (financial or otherwise)
and prospects of the Acquired Companies as it has deemed necessary or
appropriate, and that in making its decision to enter into this Agreement and to
consummate the transactions contemplated hereby it has relied solely on its own
independent investigation, analysis, and evaluation of the Acquired Companies.
Without limitation of the foregoing, Buyer acknowledges that it (i) is capable
of, and has, evaluated the Proceedings based upon the information with respect
thereto made available to the Buyer by the Seller (which information Buyer
acknowledges has excluded information that, if it were disclosed by Seller or
any of the Acquired Companies to Buyer, Seller has concluded may jeopardize any
privilege available to Seller or any of the Acquired Companies), (ii) has made
its own conclusion as to the amount or range of amounts of Losses, if any, which
the Acquired Companies may incur in respect of such Proceedings and (iii) in
making its conclusions referred to in clause (ii) of this sentence, the Buyer
has not relied on the reserves, if any, reflected therefor in the Combined
Financial Statements, as the case may be.

at least 90 calendar days' prior Notice to such effect shall be given by Buyer
to Seller, and Seller shall be given an opportunity, at its cost and expense, to
remove and retain all or any part of such books and records that Buyer elects to
dispose of. Notwithstanding the foregoing, Buyer agrees that it shall preserve
and keep all books and records of the Acquired Companies relating to any
investigation instituted by a Governmental Entity or any litigation

     information, making proposals, entering into and performing agreements to
     dispose of assets or properties, holding separate (through the
     establishment of a trust or otherwise) particular assets or categories of

party thereto other than an Acquired Company, the Seller or any of its
Affiliates and such consent is not received prior to Closing, Seller and Buyer
shall cooperate and each shall use commercially reasonable efforts to obtain
such consents to the extent required of such other parties and, if and when any
such consents are obtained, to transfer the applicable instrument, contract,
license, lease, permit, or other document, and (b) if any such consent cannot be
obtained, Buyer shall cooperate in any reasonable arrangement designed to obtain

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

Companies existing at the Closing), and, as a result, Buyer shall be obligated
at or before Closing to obtain at its sole cost and expense replacement
insurance, including insurance required by any third party to be maintained by
any of the Acquired Companies.  Buyer further acknowledges and agrees that Buyer
will need to provide to certain Governmental Entities and third parties evidence
of such replacement or substitute insurance coverage for the continued
operations of the businesses of the Acquired Companies following the Closing.
Notwithstanding Section 7.10(b), if any claims are made or losses occur prior to
                ---------------

after the Closing, then Seller shall use its reasonable commercial efforts so
that the Acquired Companies can file, notice, and otherwise continue to pursue
these claims pursuant to the terms of such policies.

           ------------------------
this Agreement, it is the explicit intent of each Party that Seller is not
making any representations or warranties whatsoever, express or implied, beyond

Marketing Company (now known as Valero Energy Corporation) and PG&E Corporation
(the "Valero Tax Agreement"), and the agreements with respect to Taxes set forth
in Article VIII of the Agreement and Plan of Merger, dated as of November 18,
   ------------
1996, between TECO Pipeline Company, et al and Pacific Gas Transmission Company
(the "TECO Tax Agreement" and, together with the Valero Tax Agreement, the
"Retained Tax Agreements"), all Tax allocation or Tax sharing agreements or
arrangements between either Company or any of the other Acquired Companies and
any other Person, including Seller or PG&E, hereby are terminated as of the
Effective Date, and no cash amounts shall be paid in respect of any amounts
owing under such agreements as of such date and all rights and obligations of
either Company and the other Acquired Companies with respect to Taxes shall be
as provided herein. Seller shall assume all obligations relating to Taxes and
rights of the Acquired Companies under the Valero Tax Agreement and under the
TECO Tax Agreement with respect to any Pre-Closing Tax Period. Seller shall be
responsible for and shall pay all Losses relating to Taxes with respect to any
Pre-Closing Tax Period under the Retained Tax Agreements, shall be entitled to
represent the interests of the Acquired Companies with respect to such matters
and shall be entitled to any payments to which any of the Acquired Companies may
be entitled thereunder. Each Acquired Company shall pay over (or cause the
recipient of any such payment to pay over) to Seller any such payments received
with respect to the Acquired Company within 10 business days after receipt
thereof. Any payments not made within such 10 business day period shall bear
interest from the date received by the Buyer or an Acquired Company at the Prime
Rate.

     11.2  Tax Return Preparation.  Each Pre-Closing Tax Return shall be
           ----------------------
prepared and filed by (or shall be the responsibility of) Seller.  All such Pre-
Closing Tax Returns shall be filed on a basis consistent with prior Tax Returns
filed by Seller or PG&E with respect to the Acquired Companies.  Seller shall
timely pay or cause to be paid all Taxes shown on such Pre-Closing Tax Returns.
Except as provided in Section 11.12 and subject to Section 11.11, Seller or PG&E
                      -------------                -------------
will include the income of the Acquired Companies (including any deferred income
triggered into income by Treasury Regulations Sections 1.1502-13 and 1.1502-14,
and any excess loss accounts taken into income under Treasury Regulation Section
1.1502-19) on the Seller or PG&E consolidated federal income Tax Returns for all
periods through the Closing and pay any federal income Taxes attributable to
such income. Buyer shall cause the Acquired Companies to furnish Tax information
to Seller or PG&E for inclusion in the federal and state consolidated or
combined income or franchise Tax returns in accordance with the past custom and
practice of the Acquired Companies.  All Tax Returns which (i) are a Post-
Closing Tax Return, or (ii) are required to be filed by or with respect to any
Acquired Company for a Tax period ending after the Closing Date, including any
Straddle Return, shall be prepared and filed by Buyer, subject to the rights to
payment under Sections 11.14 and 11.16.  Buyer shall timely pay or cause to be
              --------------     -----
paid all Taxes shown on such Tax Returns.

     11.3  Straddle Period Tax Allocation.  With respect to any Straddle
           ------------------------------
Period, to the extent permitted by Applicable Law, Seller or Buyer shall elect
to treat the Closing Date as the last day of the Tax period.  If Applicable Law
will not permit the Closing Date to be the last day of a period, the Tax
attributable to the operations of the Acquired Companies for the portion of the
period up to and including the Closing Date shall be (i) in the case of real or
personal property Taxes, Taxes imposed by the State of Texas and based on income
or capital, or a flat minimum dollar amount tax, the total amount of such Taxes
multiplied by a fraction, the numerator of

                                                        Stock Purchase Agreement
                                                                         Page 42
<PAGE>

which is the number of days in the partial period through and including the
Closing Date and the denominator of which is the total number of days in such
Straddle Period, (ii) in the case of all other Taxes based on or in respect of
income, the Tax computed on the basis of the taxable income or loss of the
Acquired Companies for such partial period as determined from its books and
records, and (iii) in the case of all other Taxes, on the basis of the actual
activities or attributes of the Acquired Companies for such partial period as
determined from its books and records.

     11.4  Straddle Returns.  With respect to any Straddle Return, Buyer shall
           ----------------
deliver, at least 45 days prior to the due date for filing such Straddle Return
(including any extension) to Seller a statement setting forth the amount of Tax
that Seller owes pursuant to Section 11.14, including the allocation of taxable
                             -------------
income and Taxes under Section 11.3, and copies of such Straddle Return,
                       ------------
including copies of any partnership returns, together with workpapers supporting
the allocation of partnership income, with respect to any partnerships in which
an Acquired Company owns an interest, with respect to the partnership Tax period
(or portion thereof) through the Closing Date. Seller shall have the right to
review such Straddle Returns and the allocation of taxable income and liability
for Taxes and to suggest to Buyer any reasonable changes to such Straddle
Returns no later than 15 days prior to the date for the filing of such Straddle
Returns. Seller and Buyer agree to consult and to attempt to resolve in good
faith any issue arising as a result of the review of such Straddle Returns and
allocation of taxable income and liability for Taxes and mutually to consent to
the filing as promptly as possible of such Straddle Returns. Not later than 5
days before the due date for the payment of Taxes with respect to such Straddle
Returns, Seller shall pay to Buyer an amount equal to the Taxes as agreed to by
Buyer and Seller as being owed by Seller pursuant to Section 11.14. If Buyer
                                                     -------------
and Seller cannot agree on the amount of Taxes owed by Seller with respect to a
Straddle Return, Seller shall pay to Buyer the amount of Taxes reasonably
determined by Buyer to be owed by Seller pursuant to Section 11.14. Within 10
                                                     -------------
days after such payment, Seller and Buyer shall refer the matter to an
independent "Big-Five" accounting firm agreed to by Buyer and Seller to
arbitrate the dispute. Seller and Buyer shall equally share the fees and
expenses of such accounting firm and its determination as to the amount owing by
Seller pursuant to Section 11.14 with respect to a Straddle Return shall be
                   -------------
binding on both Parties. Within five days after the determination by such
accounting firm, if necessary, the appropriate Party shall pay the other Party
any amount which is determined by such accounting firm to be owed. Seller shall
be entitled to reduce its obligation to pay Taxes with respect to a Straddle
Return by the amount of any estimated Taxes paid with respect to such Taxes by
or on behalf of the Acquired Companies on or before the Closing Date.

     11.5  Use of Consistent Tax Practices.  Any Tax Return which includes or
           -------------------------------
is based on the operations, ownership, assets or activities of any of the
Acquired Companies for any Pre-Closing Period, and any Tax Return which includes
or is based on the operations, ownership, assets or activities of either Company
for any Post-Closing Tax Period to the extent the items reported on such Tax
Return might reasonably be expected to increase any Tax liability of Seller or
PG&E for any Pre-Closing Tax Period or any Straddle Period, shall be prepared in
accordance with past Tax accounting practices used by the Acquired Companies,
Seller or PG&E with respect to the Tax Returns in question (unless such past
practices are no longer permissible under applicable Tax law), and to the extent
any items are not covered by past practices (or in the event

                                                        Stock Purchase Agreement
                                                                         Page 43
<PAGE>

such past practices are no longer permissible under applicable Tax law), in
accordance with reasonable Tax accounting practices selected by the Party
responsible for filing such Tax Return hereunder with the consent, not to be
unreasonably withheld or delayed, of the other Party.

     11.6  Refunds or Credits.  Except as otherwise set forth in this Agreement,
           ------------------
(i) to the extent any refunds or credits with respect to Taxes paid by the
Acquired Companies are attributable to a Pre-Closing Tax Period, such refunds or
credits shall be for the account of Seller, and (ii) to the extent that any
refunds or credits with respect to Taxes paid by the Acquired Companies are
attributable to a Post-Closing Tax Period, such refunds or credits shall be for
the account of Buyer. To the extent any refunds or credits with respect to Taxes
paid by the Acquired Companies are attributable to a Straddle Period, such
refund or credit with respect to Taxes shall be apportioned between Buyer and
Seller based on the appropriate allocation method set forth in clauses (i), (ii)
or (iii) of Section 11.3. Buyer shall cause the Acquired Companies to forward to
            ------------
to Seller or to reimburse Seller for any such refunds or credits for the account
of Seller within 10 business days from receipt thereof by any of Buyer, any of
its Affiliates or the Acquired Companies.  Seller shall forward to Buyer or
reimburse Buyer for any refunds or credits for the account of Buyer within 10
business days from receipt thereof by Seller.  Any refunds or reimbursements not
made within the 10 business day period specified above shall bear interest from
the date received by the refunding or reimbursing Party at the Prime Rate.

     11.7  Filing of Amended Returns.  Any amended Tax Return or claim for Tax
           -------------------------
refund for any Pre-Closing Tax Period shall be filed, or caused to be filed,
only by Seller or PG&E.  Seller shall not, without the prior written consent of
Buyer, make or cause to be made, any such filing, to the extent such filing, if
accepted, reasonably might be expected to increase by more than an immaterial
amount the Tax liability of Buyer for any Tax period.  An amended Tax Return or
claim for Tax refund for any Straddle Period hereunder shall be filed, or caused
to be filed, by the Party responsible for filing the original Tax Return for
such Tax period hereunder, if either Buyer or Seller so requests, except that
such filing shall not be done without the consent, which shall not be
unreasonably withheld or delayed, of Seller (if the request is made by Buyer) or
of Buyer (if the request is made by Seller).  Any amended Tax Return or claim
for Tax refund for any Post-Closing Tax Period shall be filed, or caused to be
filed, only by Buyer.  Buyer shall not, without the prior written consent of
Seller, file, or cause to be filed, any amended Tax Return or claim for Tax
refund for any Post-Closing Tax Period to the extent that such filing, if
accepted, reasonably might be expected to increase by more than an immaterial
amount the Tax liability of PG&E, Seller, or any Affiliate for any Pre-Closing
Tax Period.

     11.8  Assistance and Cooperation.  Seller, Buyer, their respective
           --------------------------
Affiliates, and the Acquired Companies shall cooperate (and cause their
Affiliates to cooperate) with each other and with each other's agents, including
accounting firms and legal counsel, in connection with Tax matters relating to
the Acquired Companies, including (i) preparation and filing of Tax Returns,
(ii) determining the liability and amount of any Taxes due, the right to and
amount of any refund of Taxes, and the liability and amount of any Tax Benefit
payments, (iii) examinations of Tax Returns, and (iv) any administrative or
judicial proceeding in respect of Taxes assessed or proposed to be assessed.

material records and other documents relating thereto, until the expiration of
the

                                                        Stock Purchase Agreement
                                                                         Page 44

applicable statute of limitations (including, to the extent notified by any
Party, any extensions thereof) of the Tax period to which such Tax Returns and
other documents and information relate or until the final determination of any
controversy with respect to such Tax period and until the final determination of
any payments that may be required with respect to such Tax period under this
Agreement or the Retained Tax Agreements, and (ii) give the other Party
reasonable written notice prior to transferring, destroying or discarding any
such Tax Returns, records and documents and, if the other Party so requests, the
Buyer or the Seller, as the case may be, shall allow the other Party to take
possession of such Tax Returns, records and documents. Each of the Parties shall
also make available to the other Parties, as reasonably requested and available,
personnel (including officers, directors, employees and agents) responsible for
preparing, maintaining, and interpreting information and providing information
or documents in connection with any administrative or judicial proceedings
relating to Taxes.

     11.9   Reimbursement for Net Tax Carrybacks.  If, after the Closing Date,
            ------------------------------------
Seller or any of its Affiliates receives or is credited with a refund of any Tax
attributable to the utilization or carryback of any Tax attribute (for example,
net operating losses and Tax credits) of any of the Acquired Companies arising
after the Closing Date, Seller shall pay to Buyer within 10 days of receipt an
amount equal to the amount of such refund together with any interest received
from or credited thereon by the applicable Taxing Authority, net of any Taxes
imposed upon Seller or such Affiliate by reason of the receipt of such refund or
credit.  Seller and PG&E will not elect to retain any net operating loss
carryovers or capital loss carryovers of the Acquired Companies under Treasury
Regulation Section 1.1502-20(g).

     11.10  Tax Deductions for Stock Option Exercises.  Buyer and Seller agree
            -----------------------------------------
that, to the maximum extent allowed by law, Seller shall be entitled to any Tax
deductions for compensation expense attributable to the exercise of options to
purchase stock in Seller or PG&E by employees (or former employees) of any of
the entities acquired by Buyer hereunder.  To the extent Seller determines that
Seller or PG&E may not be entitled to claim such deductions, Buyer agrees that,
upon Seller's request, Buyer will cause such deductions to be claimed on the
appropriate Tax Returns identified by Seller and to remit to Seller any
resulting Tax Benefit thereby derived.

     11.11  Buyer's Indemnity for Post Closing Transactions. Buyer agrees to
            -----------------------------------------------
indemnify Seller for any additional Tax owed by PG&E, Seller, or any Affiliate

     11.19  Straddle Period Tax Claims.  With respect to any Straddle Period,
            --------------------------
Buyer shall control, and Seller, or an Affiliate of Seller, at its own expense,
shall have the right to participate in, the defense and settlement of any Tax
Claim and each Party shall cooperate with the other Party and there shall be no
settlement or closing or other agreement with respect thereto without the
consent of the other Party, which consent shall not be unreasonably withheld;
provided, however, that if either Party shall refuse (the "Refusing Party") to
consent to any settlement, closing or other agreement agreed to by the relevant
Taxing Authority with respect to any such Tax Claim that the other Party (the
"Accepting Party") proposed to accept (a "Proposed Settlement"), then (i) the
Accepting Party's liability with respect to the subject matter of the Proposed
Settlement shall be limited to the amount that such liability would have been if
the Proposed Settlement had been accepted, and (ii) the Refusing Party shall be
responsible for all liabilities and expenses incurred or imposed thereafter in
connection with the contest of such Tax Claim to the extent that the final
settlement is more than the Proposed Settlement.

     11.20  Payments for Tax Benefits.  Buyer shall pay Seller the amount of
            -------------------------
any Tax Benefit resulting from any Tax deduction taken into account on or after
the Closing Date relating to any current liability that was taken into account
in computing Adjusted Working Capital as of the Effective Date.  Seller shall
pay Buyer the amount of any actual increase in Tax resulting from any taxable
income or gain taken into account by an Acquired Company after the Closing Date
with respect to the difference between the amount of an asset taken into account
in computing Adjusted Working Capital as of the Effective Date and the adjusted
tax basis of such asset for federal income tax purposes as of such date.  Any
Tax Benefit or Tax cost to be reflected on a 2000 Tax Return shall be estimated
and paid at the same time that the Adjustment Amount is settled pursuant to
Section 2.5(e).  Any difference between the estimated and actual Tax Benefit or
- --------------
Tax cost shall be settled within 30 days after the filing of any Tax Return
reflecting such Tax Benefit or Tax cost.

     11.21  Treatment of Tax Indemnity Payments.  Buyer and Seller, their
            -----------------------------------
respective Affiliates, and the Acquired Companies shall, to the extent permitted
by Applicable Law, treat any payments made pursuant to this Article 11 as
                                                            ----------
adjustments to the Purchase Price. To the extent that any such payment is not
permitted to be treated as an adjustment to the Purchase Price, the amount of
such payment shall be increased by the amount of any actual additional Tax cost
incurred as a result of the receipt of such payment. Any Tax Benefit actually
received by the recipient of such payment or any of its Affiliates as a result
of its payment of the Tax to which such indemnity payment relates shall either
reduce the amount of such indemnity payment or otherwise be paid by the
recipient to the payor of such indemnity.

     11.22  Liability for Existing Franchise Tax Claims.  Nothing in this
            -------------------------------------------
Article 11 shall impose upon Seller, PG&E, or any Affiliate of PG&E, directly or
- ----------
indirectly (including pursuant to the Retained Tax Agreements), any liability or
responsibility for any Losses that arise out of claims that are substantially
similar to those asserted in the Existing Franchise Tax Claims.

     11.23  Survival and Time Limitation.  All of the covenants, obligations
            ----------------------------
and agreements of the Parties set forth in this Article 11 shall survive the
                                                ----------

by Buyer or any Buyer Indemnitee that Seller is liable to Buyer or any Buyer
Indemnitee, or any assertion by Seller or any Seller Indemnitee that

Buyer is liable to Seller or any Seller Indemnitee, under this Article 11 must
                                                               ----------
be made in writing and must be given to the indemnifying party on or prior to
the date that is 90 days after the date on which the applicable statute of
limitations expires with respect to such matters (or not at all).

     11.24  Sole and Exclusive Remedy.  Except as otherwise provided in
            -------------------------
Sections 2.5(f), 4.14, 7.3, 7.7, 12.2(d), 12.5 and clause (ii) of Section

the exclusive agreement among the Parties (including the Seller Indemnitees and
the Buyer Indemnitees) with respect to Tax matters, including indemnification
for Tax matters.

     11.25  Purchase Price Allocation.  The Base Purchase Price shall be
            -------------------------
allocated as set forth on Schedule 11.25 which shall be used in the filing of
                          --------------
any Tax Returns.  To the extent that interest accrues or an Adjustment Amount
occurs, Buyer and Seller shall promptly make appropriate adjustments to such
allocations, and such changed allocations shall then be the allocations that
each Party to this Agreement uses.

           ----------------------------
warranties, covenants, obligations and agreements of the Parties set forth in

Agreement or the Related Agreements and the transactions contemplated hereby or
thereby (including the Acquired Companies).

     12.2  Defense of Claims.
           -----------------

     (a)   Notice.  If an Indemnitee receives notice of the assertion of any
           ------
claim or of the commencement of any Third Party Claim with respect to which
indemnification is to be sought from the Indemnifying Party, the Indemnitee will
give such Indemnifying Party reasonable prompt Notice thereof, but in any event
not later than 7 calendar days after the Indemnitee's receipt of notice of such
Third Party Claim, but the failure to give timely Notice will not affect the
rights or obligations of the Indemnifying Party except and only to the extent
that, as a result of such failure, the Indemnifying Party was substantially
disadvantaged. Such Notice shall describe the nature of the Third Party Claim in
reasonable detail and will indicate the estimated amount, if practicable, of the
Loss that has been or may be sustained by the Indemnitee. The Indemnifying Party
will have the right to participate in or, by giving Notice to the Indemnitee, to
elect to assume the defense of, any Third Party Claim at such Indemnifying
Party's own expense

                                                        Stock Purchase Agreement
                                                                         Page 50
<PAGE>

and by such Indemnifying Party's own counsel, and the Indemnitee will cooperate
in good faith in such defense at such Indemnitee's own expense.

     (b)  Defense.  If within 10 calendar days after an Indemnitee provides
          -------
Notice to the Indemnifying Party of any Third Party Claim, the Indemnitee
receives Notice from the Indemnifying Party that such Indemnifying Party has
elected to assume the defense of such Third Party Claim, the Indemnifying Party
will not be liable for any legal expenses subsequently incurred by the
Indemnitee in connection with the defense thereof. The Indemnitee shall be
entitled to participate in the defense of such Third Party Claim and to employ
counsel for such purpose at the sole cost and expense of Indemnitee. Without the
prior written consent of the Indemnitee, the Indemnifying Party will not enter
into any settlement of any Third Party Claim which would lead to liability or
create any financial or other obligation on the part of the Indemnitee for which
the Indemnitee is not entitled to indemnification hereunder, or which would
impose any injunctive or other equitable remedy on the Indemnitee. If a firm
offer is made to settle a Third Party Claim without leading to liability or the
creation of a financial or other obligation on the part of the Indemnitee for
which the Indemnitee is not entitled to indemnification hereunder (or which
would not impose any injunctive or other equitable remedy on the Indemnitee) and
the Indemnifying Party desires to accept and agree to such offer, the
Indemnifying Party will give Notice to the Indemnitee to that effect. If the
Indemnitee fails to consent to such firm offer within 10 calendar days after its
receipt of such Notice, the Indemnitee may continue to contest or defend such
Third Party Claim and, in such event, the maximum liability of the Indemnifying
Party to such Third Party Claim will be the amount of such settlement offer,
plus reasonable costs and expenses paid or incurred by the Indemnitee up to the
date of such notice.

     (c)  Direct Claim.  Any Direct Claim will be asserted by giving the
          ------------
Indemnifying Party reasonably prompt written notice thereof, stating the nature
of such claim in reasonable detail and indicating the estimated amount, if
practicable, but in any event not later than 20 calendar days after the
Indemnitee becomes aware of such Direct Claim (but the obligations of the
Indemnifying Party and the rights of the Indemnitee shall not be affected by the
failure to give such notice, except and only to the extent that, as a result of
such failure, the Indemnifying Party is substantially disadvantaged). The
Indemnifying Party will have a period of 30 calendar days within which to
respond to such Direct Claim. If the Indemnifying Party does not respond within
such 30-day period, the Indemnifying Party will be deemed to have accepted such
Direct Claim. If the Indemnifying Party rejects such Direct Claim, the
Indemnitee will be free to seek enforcement of its rights to indemnification
under this Agreement.

     (d)  Subrogation.  If the amount of any Loss, at any time subsequent to the
          -----------
making of an indemnity payment in respect thereof, is reduced by recovery,
settlement, or otherwise under or pursuant to any insurance coverage or Tax
Benefit, or pursuant to any claim, recovery, settlement or payment by or against
any other entity, the amount of such reduction, less any costs, expenses, or
premiums incurred in connection therewith, will promptly be repaid by the
Indemnitee to the Indemnifying Party. Upon making any indemnity payment, the
Indemnifying Party will, to the extent of such indemnity payment, be subrogated
to all rights of the Indemnitee against any Third Party in respect of the Loss
to which the indemnity payment relates; provided, however, that (i) the
Indemnifying Party is in compliance with its obligations under this Agreement in
respect of such Loss, (ii) until the Indemnitee recovers full payment of its
Loss,

                                                        Stock Purchase Agreement
                                                                         Page 51
<PAGE>

any and all claims of the Indemnifying Party against any such Third Party on
account of said indemnity payment are hereby made expressly subordinated and
subjected in right of payment to the Indemnitee's rights against such Third
Party, and (iii) under no circumstance shall Buyer or its Affiliates (including
the Acquired Companies) have any rights to pursue recovery under the Acquired
Company Insurance Policies. Without limiting the generality or effect of any
other provision hereof, each such Indemnitee and Indemnifying Party will execute
upon request all instruments reasonably necessary to evidence and perfect the
above-described subrogation and subordination rights. Nothing in this Section
                                                                      -------
12.2(d) shall be construed to require a Party to obtain or maintain any
- -------
insurance coverage.

     12.3  Additional Provisions Relating to Environmental Indemnification.
           ---------------------------------------------------------------
In addition to the limitations set forth elsewhere in this Article 12, Seller's

environmental matters shall be further qualified as specified below:

     (a)   Hazardous Materials.  If Buyer has a Loss pursuant to Section 12.1(a)
           -------------------                                   ---------------
of this Agreement that relates to the presence of a hazardous material that has
been released to the soils, groundwater, sediments, or otherwise to the
environment, Seller shall only be required to defend, indemnify, and hold
harmless Buyer to the extent that: (i) the facts that form a basis for such loss
constitute a breach by Seller of one or more of its representations or
warranties contained in this Agreement; (ii) investigation or remediation of the
hazardous material is required pursuant to an Applicable Environmental Law that
is in effect as of and is enforceable as of the Closing Date; (iii) such
investigation or remediation is conducted using the most cost effective methods
for investigation, remediation, or containment consistent with Applicable
Environmental Laws. To the extent that the Losses incurred in connection with an
investigation or remediation are in excess of the Losses that would be incurred
for an investigation or remediation meeting the conditions set forth in this
Section 12.3(a), Seller shall have no obligation to indemnify Buyer for such
- ---------------
excess Losses.

     (b)   Increased Costs.  If the costs of an investigation or remediation
           ---------------
that is subject to an indemnity by Seller under Section 12.1(a) or Section

- -------
Date) by a Person other than Seller or an agent, representative, or contractor
of Seller, Seller shall not be responsible for any such increase in costs
incurred. Additionally, Seller shall not be responsible for any increased Losses
that are due to (i) the closure of operations at any of the affected assets,
other than a closure resulting from a breach by Seller of its representations
and warranties set forth in Section 4.15, or (ii) a change in use of the
                            ------------
affected assets from the use of such assets as of the Closing Date.

     (c)   Buyer's Costs.  Seller shall not be responsible for the costs
           -------------
associated with Buyer's oversight of Seller's performance of its defense and
indemnity obligations under this Agreement, including the cost of Buyer's

     (e)   Sharing of Losses.  Seller shall only be required to bear and pay 50%
           -----------------
of Losses owing by Seller to Buyer or the Buyer Indemnitees under Section
                                                                  -------

     12.4  Procedures for Remedial Actions.
           -------------------------------

     (a)   Control by Seller.  Seller shall have the right, but not the
           -----------------
obligation, to control the management of an environmental investigation or
remediation that is subject to indemnification pursuant to Section 12.1(a)
                                                           ---------------
(except for on-site investigation or remediation, the management of which shall
be controlled by Buyer). Seller shall notify Buyer, within 20 calendar days of
receipt of notice of Buyer's claim for indemnification for such matter, either
that (i) it intends to undertake such responsibility, (ii) it does not intend to
undertake such responsibility, or (iii) that more information is needed from
Buyer before Seller can reasonably determine that Buyer's claim is subject to
indemnification pursuant to this Agreement. Buyer shall promptly respond to such
requests for information (to the extent such information is reasonably available
to Buyer) and, within 30 days of receipt of such information, Seller shall
notify Buyer as to whether it shall undertake the investigation and remediation.

     (b)   Seller's Investigation.  If Seller undertakes the responsibility
           ----------------------
for off-site investigation or remediation, Seller shall promptly provide copies
to Buyer of all notices, correspondence, draft reports, submissions, work plans,
and final reports and shall give Buyer a reasonable opportunity (at Buyer's own
expense) to comment on any such submissions Seller intends to deliver or submit
to the appropriate Governmental Entity prior to such submission. Buyer may, at
its own expense, hire its own consultants, attorneys, or other professionals to
monitor the investigation or remediation, including any field work undertaken by
Seller, and Seller shall provide Buyer with the results of all such field work.
Notwithstanding the above, Buyer shall not take any actions that shall
unreasonably interfere with Seller's performance of the investigation and
remediation. Seller shall undertake any such work required herein in a manner
designed to minimize any disruption, to the greatest extent possible, in the
conduct of operations at the affected assets. Buyer shall allow Seller
reasonable access to conduct any of the work contemplated herein and shall fully
cooperate with Seller in the performance of the investigation and remediation,
including providing Seller with reasonable access to employees and documents as
necessary.

     (c)   Buyer's Investigation.  For all on-site investigation and
           ---------------------
remediation, or if Seller declines to undertake the performance of an off-site
investigation and remediation hereunder, Buyer shall be entitled to undertake
the investigation and remediation. Buyer shall promptly provide copies to Seller
of all notices, correspondence, draft reports, submissions, work plans and final
reports and shall give Seller a reasonable opportunity (at Seller's own expense)
to comment on any submissions Buyer intends to deliver or submit to the
appropriate Governmental Entity prior to said submission. Seller may, at its own
expense, hire its own consultants, attorneys or other professionals to monitor
the investigation and remediation, including any field work undertaken by Buyer,
and Buyer shall provide Seller with the results of all such field work.
Notwithstanding the above, Seller shall not take any action that shall
unreasonably interfere with Buyer's performance of investigation and
remediation.

     12.5  Tax Treatment of Indemnity Payments.  Each Party, to the extent
           -----------------------------------
permitted by Applicable Law, agrees to treat any payments made pursuant to this
Article 12 as adjustments to the Purchase Price for all federal and state income
- ----------
and franchise Tax purposes.  To the extent that any such payment is not
permitted to be treated as an adjustment to the Purchase Price, the amount of
such payment shall be increased by the amount of any actual additional Tax cost
incurred as a result of the receipt of such payment.

_______, 2000


El Paso Field Services Company
1001 Louisiana Street
Houston, Texas 77002

Ladies and Gentlemen:

     I am Senior Vice President and General Counsel of PG&E Corporation, the
corporate parent of PG&E National Energy Group, Inc. ("Seller"). In such
capacity, I, or the attorneys working under my supervision, have acted as
counsel for Seller and reviewed (i) the Stock Purchase Agreement, dated as of
January 27, 2000 (the "Purchase Agreement"), between Seller and El Paso Field
Services Company ("Buyer"), providing for, among other things, the sale to Buyer
by Seller of all of the issued and outstanding shares of capital stock of PG&E
Gas Transmission, Texas Corporation, a Delaware corporation and PG&E Gas
Transmission Teco, Inc., a Delaware corporation (ii) the Transition Services
Agreement and the Termination and Assignment Agreement entered into by Seller
and Buyer in connection with the transactions contemplated by the Purchase
Agreement (the "Related Agreements"), (iii) the PG&E Guaranty, and (iv) the EPE
Guaranty, and such certificates of public officials, organizational documents,
and other records of the Seller and other certificates and instruments as I, or
they, have deemed necessary for the purpose of the opinions herein expressed.
This opinion is rendered pursuant to Section 3.3(b)(i) of the Purchase
Agreement. Unless otherwise defined in this opinion, terms used herein that are
defined in the Purchase Agreement shall have the meanings given to them in the
Purchase Agreement.

     In rendering the opinions expressed below, I have assumed that (i) each of
Buyer and PG&E is duly formed, validly existing, and in good standing under the
laws of its jurisdiction of existence, (ii) Buyer has full power and authority
to execute the Purchase Agreement and the Related Agreements to which Buyer is a
Party and to consummate the transactions contemplated thereby, (iii) EPE has
full power and authority to execute the EPE Guaranty, (iv) Buyer has taken all
necessary action to authorize execution of the Purchase Agreement and the
Related Agreements to which Buyer is a Party on its behalf by the person
executing the same, (v) EPE has taken all necessary action to authorize
execution of the EPE Guaranty, (vi) Buyer has properly executed and delivered
the Purchase Agreement and the Related Agreements to which Buyer is a Party,
(vii) EPE has properly executed and delivered the EPE Guaranty, and (viii) the
Purchase Agreement and the Related Agreements to which Buyer is a Party, and the
EPE Guaranty, are each enforceable against Buyer and, in the case of the EPE
Guaranty, EPE in accordance with its terms, subject to (A) the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium, or fraudulent
transfer laws, or any other laws or judicial decisions affecting creditors'
rights and remedies generally, and (B) the effect of the general principles of
equity (regardless of whether enforcement is considered in a proceeding at law
or in equity).

                                                                          Page 2
<PAGE>

     In rendering the opinions expressed below, I have assumed the genuineness
of all signatures, the legal capacity, and the authority of all natural persons
signing the Purchase Agreement, the Related Agreements and the EPE Guaranty on
behalf of the parties thereto (other than the officers of the Seller), the
authenticity of all documents submitted to me as certified, conformed, or
photostatic copies, the authenticity of the originals of such copies, and the
absence of evidence extrinsic to the provisions of the Purchase Agreement, the
Related Agreements, the EPE Guaranty, and the PG&E Guaranty.

     I am a member of the Bar of the State of California, and I do not herein
express any opinion as to the law of any state other than the State of
California, except for the General Corporation Law of the State of Delaware, and
the federal laws of the United States of America.

     Based on the foregoing and subject to the qualifications set forth below, I
am of the opinion that:

1. The Seller is a corporation duly organized, validly existing, and in good
   standing under the laws of the State of Delaware. PG&E is a corporation duly
   organized, validly existing and in good standing under the laws of the State
   of California.

2. The Seller has the corporate power and authority to execute, deliver, and
   perform its obligations under the Purchase Agreement and the Related
   Agreements. PG&E has the corporate power and authority to execute, deliver,
   and perform its obligations under the PG&E Guaranty.

3. The execution and delivery of the Purchase Agreement and the Related
   Agreements by the Seller and the performance of the Seller's obligations
   under the Purchase Agreement and the Related Agreements have been duly
   authorized by all requisite action of the Seller, and the Purchase Agreement
   and the Related Agreements has been duly executed and delivered by the
   Seller.

4. The execution and delivery of the PG&E Guaranty by PG&E and the performance
   of the obligations under the PG&E Guaranty have been duly authorized by all
   requisite action of PG&E, and the PG&E Guaranty has been duly executed and
   delivered by PG&E.

5. The execution and delivery by the Seller of the Purchase Agreement and the
   Related Agreements does not, and the performance by the Seller of its
   obligations thereunder will not contravene, conflict with or result in any
   breach of any of the provisions of, or constitute a default under, (i) the
   certificate of incorporation or by-laws of the Seller; (ii) any law, rule,
   regulation, or ordinance applicable to the Seller; or (iii) to my actual
   knowledge (A) any material agreement, contract, or instrument to which the
   Seller is a party or by which the Seller or any of its properties is bound,
   or (B) any writ, judgment, injunction, decree, determination, or award of any
   court or other governmental authority by which the Seller or any of its
   properties is bound.

6. The execution and delivery by PG&E of the PG&E Guaranty does not, and the
   performance

                                                                          Page 3
<PAGE>

   by PG&E of its obligations thereunder will not, contravene, conflict with or
   result in any breach of any of the provisions of, or constitute a default
   under, (i) the certificate of incorporation or by-laws of PG&E; (ii) any law,
   rule, regulation, or ordinance applicable to PG&E; or (iii) to my actual
   knowledge (A) any material agreement, contract, or instrument to which PG&E
   is a party or by which PG&E or any of its properties is bound, or (B) any
   writ, judgment, injunction, decree, determination, or award of any court or
   other governmental authority by which PG&E or any of its properties is bound.

7. No consent, order, authorization, waiver, approval, or any other action by,
   or registration, declaration or filing with, any governmental authority is
   required for the Seller to enter into the Purchase Agreement and the Related
   Agreements or for the Seller to perform and to be legally bound to perform
   its obligations thereunder.

8. No consent, order, authorization, waiver, approval, or any other action by,
   or registration, declaration or filing with, any governmental authority is
   required for PG&E to enter into the PG&E Guaranty or for PG&E to perform and
   to be legally bound to perform its obligations thereunder.

9. There is no action, suit, legal or arbitral proceeding or investigation at
   law or in equity or by or before any court or administrative agency pending
   or to my actual knowledge threatened against the Seller which may have a
   material adverse effect on the Seller's ability to perform its obligations
   under the Purchase Agreement and the Related Agreements.

10.There is no action, suit, legal or arbitral proceeding or investigation at
   law or in equity or by or before any court or administrative agency pending
   or to my actual knowledge threatened against PG&E which may have a material
   adverse effect on the PG&E's ability to perform its obligations under the
   PG&E Guaranty.

     As counsel to the Seller, I am furnishing this letter to you at your
request and solely for the benefit of the named addressees hereof in connection
with the transactions contemplated by the Purchase Agreement, the Related
Agreements and the PG&E Guaranty. This letter is not to be quoted or relied upon
by any other person or firm, or used for any other purpose, without my express
written consent.

     This opinion is rendered as of the date first set forth above, and I
expressly disclaim any obligation to update this opinion from and after the date
hereof.

Very truly yours,

                   [ Letterhead of Andrews & Kurth, L.L.P. ]




                              ____________, 2000



El Paso Field Services Company
1001 Louisiana Street
Houston, Texas 77002

Ladies and Gentlemen:

          We have acted as counsel for PG&E National Energy Group Inc., a
Delaware corporation ("Seller"), in connection with the preparation, execution
and delivery of (i) the Stock Purchase Agreement, dated January 27, 2000 (the
"Purchase Agreement"), between the Seller and El Paso Field Services Company, a
Delaware corporation ("Buyer"), (ii) the Transition Services Agreement and the
Termination and Assignment Agreement entered into by Seller and Buyer in
connection with the transactions contemplated by the Purchase Agreement (the
"Related Agreements"). This opinion is rendered pursuant to Section 3.3(b)(ii)
of the Purchase Agreement. Capitalized terms not otherwise defined herein shall
have the meanings given to them in the Purchase Agreement.

     For purposes of this opinion, we have also examined the following documents
and records:

               1.  The Certificate of Incorporation, as amended, of Seller,
               certified as of a recent date by the Secretary of State of
               Delaware to be true and correct;

               2.   A copy of the Bylaws of Seller, certified as of a recent
               date by the Secretary of Seller to be true and correct;

               3.  An executed copy or counterpart of the Purchase Agreement,
               the Related Agreements, the PG&E Guaranty, and the EPE Guaranty;
               and

               4.  Such other documents and agreements as we have deemed
               necessary for purposes of this opinion.
<PAGE>

          For purposes of this opinion, we have examined such statutes,
regulations and such other corporate records and documents and certificates of
corporate and public officials as we have deemed necessary for the purposes of
this opinion. We have also examined the original, certified, conformed or
photostatic copies of such other documents, records, agreements and certificates
as we have considered relevant hereto. In all such examinations, we have assumed
the authenticity of all documents submitted to us as originals, and the
conformity to original documents of all copies submitted to us as certified,
conformed or photostatic copies, which facts we have not verified independently.
As to certificates of public officials, we have assumed the same to have been
properly given and to be accurate. We have relied, as to the matters set forth
therein, on certificates and telegrams of public officials and the
representations and warranties of Seller and Buyer contained in the Purchase
Agreement. As to matters of fact to which this opinion pertains, we have relied
upon (i) certificates of certain officers of the Seller, and (ii) the
representations and warranties of Seller contained in the Purchase Agreement. We
have also assumed that the Purchase Agreement and each of the Related Agreements
have been duly authorized, executed and delivered by each party of Seller and
Buyer, and constitute the legal, valid and binding obligations of Buyer,
enforceable against Buyer in accordance with their terms subject to (A) the
effect of any applicable bankruptcy, insolvency, reorganization, moratorium, or
fraudulent transfer laws, or any other laws or judicial decisions affecting
creditors' rights and remedies generally and (B) the effect of general
principles of equity (regardless of whether enforcement is considered in a
proceeding at law or in equity).

          Based upon the foregoing, and having due regard for such legal
considerations as we have deemed relevant, we are of the opinion that the
Purchase Agreement and the Related Agreements constitute legal, valid and
binding obligations of the Seller, enforceable against the Seller in accordance
with their terms.

          The foregoing opinion regarding the enforceability of the Purchase
Agreement and the Related Agreements is subject to the following qualifications:

                    (a) The enforceability of the Purchase Agreement and the
               Related Agreements may be limited or adversely affected by (i)
               bankruptcy, insolvency, reorganization, moratorium, liquidation,
               rearrangement, fraudulent transfer, fraudulent conveyance and
               other similar laws (including court decisions) now or hereafter
               in effect and affecting the rights and remedies of creditors
               generally or providing for the relief of debtors generally, (ii)
               the refusal of a particular court to grant equitable remedies,
               including but without limiting the generality of the foregoing,
               specific performance and injunctive relief, and (iii) general
               principles of equity (regardless of whether such remedies are
               sought in a proceeding in equity or at law).

                    (b) In rendering the foregoing opinions, we express no
               opinion as to the enforceability of provisions of the Purchase
               Agreement and the Related
<PAGE>

               Agreements (i) restricting access of Seller or Buyer to courts or
               to legal or equitable remedies, (ii) purporting to waive or
               affect rights, claims, defenses or other benefits bestowed by law
               to the extent that any of the same cannot be waived or so
               affected, (iii) relating to indemnities to the extent prohibited
               by public policy or to the extent indemnification is required for
               losses or expenses caused by gross negligence, willful
               misconduct, fraud, or illegal action on the part of an
               indemnified party, or for negligence on the part of an
               indemnified party unless such indemnification for negligence is
               expressly and conspicuously provided for in the Purchase
               Agreement or the Related Agreements, or (iv) purporting to waive
               or to otherwise affect the rights of third parties.
               Notwithstanding the limitations set forth above in this
               paragraph, the Purchase Agreement and the Related Agreements each
               contain adequate provisions for the practical realization of the
               principal legal benefits afforded thereby except for the economic
               consequences resulting from any delay or procedure imposed by
               applicable law.

          The foregoing opinion is  expressly limited to the laws of the State
of Texas, the General Corporation Law of the State of Delaware, and the Federal
laws of the United States of America.

          The opinion expressed herein is solely for the benefit of and may only
be relied upon by, the named addressee hereof in connection with the
transactions contemplated by the Purchase Agreement and the Related Agreements.
This opinion may not be relied upon by any other person without our prior
written consent. The opinion expressed herein is limited to the date hereof, and
we make no undertaking to amend or supplement such opinion as facts and
circumstances come to our attention or changes in law occur which could affect
such opinion.

                              Very truly yours,

                          Opinion of Counsel to Buyer



PG&E National Energy Group, Inc.
c/o PG&E Energy Trading
1100 Louisiana Street
Suite No. 1000
Houston, Texas 77002

Gentlemen:

          We have acted as counsel for El Paso Energy Corporation, a Delaware
corporation ("EPE"), and El Paso Field Services Company, a Delaware corporation
("Buyer"), in connection with the negotiation and execution (i) the Stock
Purchase Agreement, dated as of January 27, 2000 (the "Purchase Agreement"),
between Buyer and PG&E National Energy Group, Inc., a Delaware corporation
("Seller"), providing for, among other things, the purchase by Buyer from Seller
of all of the issued and outstanding shares of capital stock of PG&E Gas
Transmission, Texas Corporation, a Delaware corporation and PG&E Gas
Transmission Teco, Inc., a Delaware corporation, (ii) the Transition Services
Agreement and Termination and Assignment Agreement entered into by Buyer in
connection with the transactions contemplated by the Purchase Agreement (the
"Related Agreements"), (iii) the PG&E Guaranty, and (iv) the EPE Guaranty.
Unless otherwise defined in this opinion, terms used herein that are defined in
the Purchase Agreement shall have the meanings given to them in the Purchase
Agreement.  This opinion is being delivered pursuant to Section 3.3(b) of the
Purchase Agreement.

          In connection with the opinions expressed below, we have examined the
following:

          (a)  a copy, certified by the Secretary of State of the State of
Delaware to be a true copy, of the Certificate of Incorporation of the Buyer;

          (b)  a copy, certified by the Secretary of the Buyer to be a true
copy, of the Bylaws of the Buyer;

          (c)  copies of letters, certificates or telegrams received by us from
public officials in the State of Delaware as to the due incorporation, valid
existence and good standing of the Buyer;

          (d)  copies, certified by the Secretary of the Company to be true
copies, of minutes of certain resolutions duly adopted by the Board of Directors
of the Buyer on ____________, 2000;

                                                                         Page 17
<PAGE>

                                                                  Exhibit 3.3(e)
                                                     to Stock Purchase Agreement

          (e)  an executed original or counterpart of the Purchase Agreement,
the Related Agreements, the PG&E Guaranty, and the EPE Guaranty;

          (f)  such other documents as we have deemed appropriate for purposes
of the opinions expressed below.

          In addition, we have examined all statutes, corporate records, and
other instruments that we have deemed necessary to examine for the purpose of
this opinion.

          In rendering the opinions herein set forth, we assumed that (i) Seller
is duly formed, validly existing, and in good standing under the laws of its
jurisdiction of organization, (ii) Seller has full power and authority to
execute the Purchase Agreement and the Related Agreements and to consummate the
transactions contemplated thereby, (iii) Seller has taken all necessary action
to authorize execution of the Purchase Agreement and the Related Agreements on
its behalf by the person executing the same, (iv) Seller has properly executed
and delivered the Purchase Agreement and the Related Agreements, and (v) the
Purchase Agreement and the Related Agreements are each enforceable against
Seller in accordance with their terms subject to (A) the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium, or fraudulent
transfer laws, or any other laws or judicial decisions affecting creditors'
rights and remedies generally and (B) the effect of general principles of equity
(regardless of whether enforcement is considered in a proceeding at law or in
equity).

          Based upon the foregoing and subject to the qualifications set forth
below, we are of the opinion that:

          1.   Each of Buyer and EPE is a corporation duly incorporated and
               validly existing and in good standing under the laws of its
               jurisdiction of organization.

          2.   Buyer has the requisite corporate power and authority to execute
               and deliver the Purchase Agreement and the Related Agreements and
               to perform the transactions contemplated thereby. EPE has the
               requisite corporate power and authority to execute and deliver
               the EPE Guaranty and to perform the transactions contemplated
               thereby.

          3.   The execution, delivery, and performance by Buyer of the Purchase
               Agreement and the Related Agreements have been duly authorized by
               all necessary corporate action on the part of Buyer.

          4.   The execution, delivery, and performance by EPE of the EPE
               Guaranty has been duly authorized by all necessary corporate
               action on the part of EPE.

          5.   The execution and delivery of the Purchase Agreement by Buyer and
               the Related Agreements does not, and the consummation by Buyer of
               the transactions contemplated thereby will not, conflict with or
               result in a

                                            Exhibits to Stock Purchase Agreement
                                                                         Page 18
<PAGE>

                                                                  Exhibit 3.3(e)
                                                     to Stock Purchase Agreement

               breach of any of the provisions of, or constitute a default
               under, (i) the Certificate of Incorporation or Bylaws of Buyer,
               (ii) any law, rule, regulation or ordinance applicable to Buyer
               or any of its properties or require Buyer to obtain any approval,
               consent, or waiver of, or to make any filing with, any
               governmental or regulatory agency or administrative body, in each
               case that has not been obtained or made, or (iii) any material
               agreement, contract or instrument to which the Buyer is a party
               or by which the Buyer or any of its properties is bound or any
               writ, judgment, injunction, decree, determination, or award of
               any court or other governmental authority by which the Buyer or
               any of its properties is bound.

          6.   The execution and delivery of the EPE Guaranty by EPE does not,
               and the consummation by EPE of the transactions contemplated
               thereby will not, conflict with or result in a breach of any of
               the provisions of, or constitute a default under, (i) the
               Certificate of Incorporation or Bylaws of EPE, (ii) any law,
               rule, regulation or ordinance applicable to EPE or any of its
               properties or require EPE to obtain any approval, consent, or
               waiver of, or to make any filing with, any governmental or
               regulatory agency or administrative body, in each case that has
               not been obtained or made, or (iii) any material agreement,
               contract or instrument to which EPE is a party or by which EPE or
               any of its properties is bound or any writ, judgment, injunction,
               decree, determination, or award of any court or other
               governmental authority by which the EPE or any of its properties
               is bound.

          7.   No consent, order, authorization, waiver, approval, or any other
               action by, or registration, declaration or filing with, any
               governmental authority is required for the Buyer to enter into
               the Purchase Agreement and the Related Agreements, for EPE to
               enter into the Guaranty Agreement, or for Buyer or EPE, as the
               case may be, to perform and to be legally bound to perform its
               obligations thereunder.

          8.   There is no action, suit, legal or arbitral proceeding or
               investigation at law or in equity or by or before any court or
               administrative agency pending or, to our actual knowledge,
               threatened against the Buyer or EPE which may have a material
               adverse effect on (i) the Seller's ability to perform its
               obligations under the Purchase Agreement and the Related
               Agreements or (ii) EPE's ability to perform its obligations under
               the EPE Guaranty.

          9.   The Purchase Agreement and Related Agreements each constitute the
               legal, valid, and binding obligation of Buyer enforceable against
               Buyer in accordance with their terms.

          10.  The EPE Guaranty constitutes the legal, valid, and binding
               obligation of EPE enforceable against EPE in accordance with
               their terms.

                                                     to Stock Purchase Agreement

The foregoing opinions regarding the enforceability of the Purchase Agreement
and the Related Agreements are subject to the following qualifications:

               (a)  The enforceability of the Purchase Agreement, the Related
          Agreements and the EPE Guaranty may be limited or adversely affected
          by (i) bankruptcy, insolvency, reorganization, moratorium,
          liquidation, rearrangement, fraudulent transfer, fraudulent conveyance
          and other similar laws (including court decisions) now or hereafter in
          effect and affecting the rights and remedies of creditors generally or
          providing for the relief of debtors generally, (ii) the refusal of a
          particular court to grant equitable remedies, including but without
          limiting the generality of the foregoing, specific performance and
          injunctive relief, and (iii) general principles of equity (regardless
          of whether such remedies are sought in a proceeding in equity or at
          law).

               (b)  In rendering the foregoing opinions, we express no opinion
          as to the enforceability of provisions of the Purchase Agreement, the
          Related Agreements, and the EPE Guaranty (i) restricting access of
          Seller or Buyer or, in the case of the EPE Guaranty, EPE to courts or
          to legal or equitable remedies, (ii) purporting to waive or affect
          rights, claims, defenses or other benefits bestowed by law to the
          extent that any of the same cannot be waived or so affected, (iii)
          relating to indemnities to the extent prohibited by public policy or
          to the extent indemnification is required for losses or expenses
          caused by gross negligence, willful misconduct, fraud, or illegal
          action on the part of an indemnified party, or for negligence on the
          part of an indemnified party unless such indemnification for
          negligence is expressly and conspicuously provided for in the Purchase
          Agreement, the Related Agreements or the EPE Guaranty, or (iv)
          purporting to waive or to otherwise affect the rights of third
          parties. Notwithstanding the limitations set forth above in this

          realization of the principal legal benefits afforded thereby except

3.   Employer Contributions
     ----------------------

     (a)  Matching Employer Contributions.  Subject to the provisions of Section
          -------------------------------
          13, the Eligible Employee's Account shall be credited for each Plan
          Year with a Matching Employer Contribution, calculated in the manner
          provided in Sections 3(a) (1), (2), and (3) below:

                                      -3-
<PAGE>

          (1)  First, an amount shall be calculated equal to the maximum
               matching contribution that would be made under the terms of the
               RSP, taking into account for such Plan Year the amount of pre-tax
               deferrals and after-tax contributions the Eligible Employee
               elected under the RSP. For purposes of this calculation, any
               amounts deferred under Subsection 4(a) of this Plan shall be
               treated as pre-tax deferrals under the RSP.

          (2)  The calculation made in accordance with this Section 3(a) (1)
               above shall be made without regard to any limitation on such
               amounts under the RSP resulting from the application of any of
               the limitations under Code Sections 401(m), 401(a)(17), or 415.

          (3)  The Employer Matching Contribution to be credited to the Account
               of an Eligible Employee for any Plan Year shall equal the amount
               calculated in accordance with Sections 3(a) (1) and (2) above,
               reduced by the amount of matching contribution made to such
               Eligible Employee's account for such Plan Year under the RSP.

     (b)  Crediting of Matching Employer Contributions.  Matching Employer
          --------------------------------------------
          Contributions shall be calculated and credited to the Eligible
          Employee's Account as of the first business day of the calendar year
          following the Plan Year and shall be credited only if the Eligible
          Employee is an Employee on the last day of Plan Year for which the
          amounts are credited.

     (c)  Basic Employer Contributions.  Subject to the provisions of Section
          ----------------------------
          13, the Account of each Eligible Employee shall be credited for each
          Plan Year with a Basic Employer Contribution, calculated in the manner
          provided in Sections 3(c) (1), (2), and (3) below:

          (1)  First, an amount shall be calculated equal to the Basic Employer
               Contribution that would be made under the terms of the RSP,
               taking into account for such Plan Year the Eligible Employee's
               Covered Compensation under the RSP, before any deductions for
               compensation deferrals elected by such Eligible Employee under
               Subsection 4(a) of this Plan. For Eligible Employees as defined
               by Section 2(e)(1) of this Plan, compensation shall also reflect
               such Eligible Employee's Short Term Incentive Plan awards.

          (2)  The calculation made in accordance with this Section 3(c)(1)
               above shall be made without regard to any limitation on such
               amounts under the RSP resulting from the application of any of
               the limitations under Code Sections 401(a)(4), 401(a)(17), or
               415.

          (3)  The Employer Contribution to be credited to the Account of an
               Eligible Employee for any Plan Year shall equal the amount
               calculated in accordance with Sections 3(c)(1) and (2) above,
               reduced by the amount of Basic Employer Contributions made to
               such Eligible Employee's account for such Plan Year under the
               RSP.

                                      -4-

     (d)  Crediting of Basic Employer Contributions.  The Employer Contribution
          -----------------------------------------
          attributable to an Eligible Employee's Short Term Incentive Plan award
          shall be credited to an Eligible Employee's Account as of the first
          business day of the month following the date on which the Short Term
          Incentive Plan award is paid. All other Employer Contributions made in
          respect of an Eligible Employee shall be credited to the Eligible
          Employee's Account as of the first business day of the calendar year
          following the Plan Year and shall be credited only if the Eligible
          Employee is an Employee on the last day of the Plan Year for which the
          amounts are credited.

     (e)  FICA Taxes.  All amounts credited to an Eligible Employee's Account
          ----------
          under Section 3 shall be net of FICA taxes withheld on behalf of such
          Eligible Employee.

4.   Eligible Employee Deferrals
     ---------------------------

     (a)  Amount of Deferral.  An Eligible Employee may defer (i) 5 percent to
          ------------------
          50 percent of his or her annual salary; and (ii) all or part of his or
          her Short Term Incentive Plan awards, Long Term Incentive Plan awards
          (other than stock options), Perquisite Allowances, and any other
          special payments, awards, or bonuses as authorized by the Plan
          Administrator.

     (b)  Credits to Accounts.  Salary deferrals shall be credited to an
          -------------------
          Eligible Employee's Account as of each payroll period. All other
          deferrals attributable to allowances, awards, bonuses, and other
          payments shall be credited as of the date that they otherwise would
          have been paid.

     (c)  Deferral Election.  An Eligible Employee must file an election form
          -----------------
          with the Plan Administrator which indicates the percentage of salary
          and applicable pay periods, and the amount of any awards, allowances,
          payments, and bonuses to be deferred under the Plan. Notwithstanding
          the foregoing, upon first becoming an Eligible Employee, an election
          to defer shall be effective for the month following the filing of a
          Deferral Election Form, provided said Form is filed within 60 days
          following the date when the employee first becomes an Eligible
          Employee.

     (d)  Deferral of Special Incentive Stock Ownership Premiums.  All of an
          ------------------------------------------------------
          Eligible Employee's Special Incentive Stock Ownership Premiums are
          automatically deferred to the Plan immediately upon grant and
          converted into units in the PG&E CORP Phantom Stock Fund. The units
          attributable to Special Incentive Stock Ownership Premiums and any
          additional units resulting from the conversion of dividend equivalents
          thereon remain unvested until the earlier of the third anniversary of
          the date on which the Special Incentive Stock Ownership Premiums are
          credited to an Eligible Employee's account (provided the Eligible
          Employee continues to be employed on such date), death, disability, or
          retirement of the participant, or upon a Change in Control as defined
          in the PG&E Corporation Long-Term Incentive Program (LTIP). (The term
          "disability" shall, for purposes of the Plan, have the same meaning as
          in Section 22(e)(3) of the Internal Revenue Code.) Unvested units
          attributable to Special Incentive Stock Ownership Premiums and any
          additional units resulting from the conversion of dividend equivalents
          thereon shall be forfeited upon termination of the Eligible Employee's
          employment unless otherwise provided in the PG&E Corporation Officer
          Severance Policy, or if an Eligible Employee's stock ownership falls
          below the levels set forth in the Executive Stock Ownership Program.

                                      -5-

5.   Investment Funds
     ----------------

     (a)  Although no assets will be segregated or otherwise set aside with
          respect to an Eligible Employee's Account, the amount that is
          ultimately payable to the Eligible Employee with respect to such
          Account shall be determined as if such Account had been invested in
          some or all of the Investment Funds. The Plan Administrator, in its
          sole discretion, shall adopt (and modify from time to time) such rules
          and procedures as it deems necessary or appropriate to implement the
          deemed investment of the Eligible Employees' Accounts. Such procedures
          generally shall provide that an Eligible Employee's Account shall be
          deemed to be invested among the three Investment Funds in the manner
          elected by the Eligible Employee in such percentages and manner as
          prescribed by the Plan Administrator. In the event no election has
          been made by the Eligible Employee, such Account will be deemed to be
          invested in the AA Utility Bond Fund. Eligible Employees shall be able
          to reallocate their Accounts between the Investment Funds and
          reallocate amounts newly credited to their Accounts at such time and
          in such manner as the Plan Administrator shall prescribe. Anything to
          the contrary herein notwithstanding, an Eligible Employee may not
          reallocate Account balances between Investment Funds if such
          reallocation would result in a non-exempt Discretionary Transaction as
          defined in Rule 16b-3 of the Securities Exchange Act of 1934, as
          amended, or any successor to Rule 16b-3, as in effect when the
          reallocation is requested.

          (1)  AA Utility Bond Fund. On the first business day of each calendar
               quarter, interest shall be credited on the amounts invested in
               the AA Utility Bond Fund as of the last business day of the
               immediately preceding calendar quarter and prorated based on the
               number of days in the quarter that the balance was allocated to
               the AAA Utility Bond Fund. Such interest shall be at a rate equal
               to the AA Utility Bond Yield reported in Moody's Public Utility,
                                                        ----------------------
               published in the issue of Moody's Investors Service immediately
                                         -------------------------
               preceding the first day of the calendar quarter in which the
               interest is to be credited. Such interest shall become a part of
               the Eligible Employee's Account and shall be paid at the same
               time or times as the balance of the Eligible Employee's Account.
               Notwithstanding the above, if before the end of the quarter an
               Eligible Employee has requested that his or her Account balance
               be reallocated to another Investment Fund(s) or the Eligible
               Employee's Account balance has been paid to the Eligible Employee
               or to the Eligible Employee's beneficiary, prorated interest on
               the Eligible Employee's Account balance shall be calculated at a
               rate equal to the AA Utility Bond Yield reported in Moody's
                                                                   -------
               Public Utility, published in the issue of Moody's Investors
               --------------                            -----------------
               Service immediately preceding the date of such reallocation or
               -------
               payment and shall be credited to the Eligible Employee's Account
               in such other Investment Fund(s) on the date of reallocation or
               paid directly to the Eligible Employee or the Eligible Employee's
               beneficiary, whichever is applicable.

          (2)  PG&E CORP Phantom Stock Fund. Amounts credited to the PG&E CORP
               Phantom Stock Fund shall be converted into units (including
               fractions computed to three decimal places) each representing a
               share of PG&E CORP common stock. The value of a unit for purposes
               of determining the number of units to credit upon initial
               allocation or upon reallocation from another Investment Fund, and
               for determining the dollar value of the aggregate number of units
               to be reallocated from the PG&E CORP Phantom Stock Fund to
               another Investment Fund and for

                                      -6-
<PAGE>

               distributions from the Plan, shall be the average of the daily
               high and low price of a share of PG&E CORP common stock as traded
               on the New York Stock Exchange for the 30 trading days preceding
               the date that (i) amounts are credited to an Eligible Employee's
               Account in the PG&E CORP Phantom Stock Fund, or (ii) the Plan
               Administrator receives a reallocation request, in the case of
               reallocations. Thereafter, the value of a unit shall fluctuate in
               accordance with the closing price of PG&E CORP common stock on
               the New York Stock Exchange. Each time that PG&E CORP pays a
               dividend on its common stock, an amount equal to such dividend
               payable with respect to each share of PG&E CORP common stock,
               multiplied by the number of units credited to an Eligible
               Employee's Account, shall be credited to the Eligible Employee's
               Account and converted into additional units. The number of
               additional units shall be calculated by dividing the aggregate
               amount of credited dividends, i.e. the dividend multiplied by the
               number of units credited to the Eligible Employee's Account as of
               the dividend record date, by the closing price of a share of PG&E
               CORP common stock on the New York Stock Exchange on the dividend
               payment date. If, after the record date but before the dividend
               payment date, an Eligible Employee's balance in the PG&E CORP
               Phantom Stock Fund has been reallocated to another Investment
               Fund(s) or has been paid to the Eligible Employee or to the
               Eligible Employee's beneficiary, then an amount equal to the
               aggregated dividend shall be credited to the Eligible Employee's
               Account in such other Investment Fund(s) or paid directly to the
               Eligible Employee or the Eligible Employee's beneficiary,
               whichever is applicable.

          (3)  S&P 500 Index Fund. Amounts credited to the S&P 500 Index Fund
               shall be converted into units each representing a LCSF unit held
               in the RSP on the date of allocation. Thereafter, the value of a
               unit held in the S&P Index Fund shall be determined in the same
               manner as the value of a LCSF unit under Section 18 of the RSP.

6.   Accounting
     ----------

     (a)  Eligible Employees' Accounts.  At the direction of the Plan
          ----------------------------
          Administrator, there shall be established and maintained on the books
          of the Employer, a separate account for each Eligible Employee in
          order to reflect his or her interest under the Plan.

     (b)  Investment Earnings.  Each Eligible Employee's Account shall initially
          -------------------
          reflect the value of his or her Account's interest in each of the
          Investment Funds, deemed acquired with the amounts credited thereto.
          Each Eligible Employee's Account shall also be credited (or debited)
          as of the end of each day with the net appreciation (or depreciation),
          earnings and gains (or losses) with respect to the investments deemed
          made by his or her Account. Any such net earnings or gains deemed
          realized with respect to any investment of any Eligible Employee's
          Account shall be deemed reinvested in additional amounts of the same
          investment and credited to the Eligible Employee's Account.

                                      -7-
<PAGE>

     (c)  Accounting Methods.  The accounting methods or formulae to be used
          ------------------
          under the Plan for the purpose of maintaining the Eligible Employees'
          Accounts shall be determined by the Plan Administrator. The accounting
          methods or formulae selected by the Plan Administrator may be revised
          from time to time but shall conform to the extent practicable with the
          accounting methods used under the Applicable Plan.

     (d)  Valuations and Reports.  The fair market value of each Eligible
          ----------------------
          Employee's Account shall be determined as of each Valuation Date. In
          making such determinations and in crediting net deemed earnings and
          gains (or losses) in the Investment Funds to the Eligible Employees'
          Accounts, the Plan Administrator (in its discretion) may employ such
          accounting methods as the Plan Administrator (in its discretion) may
          deem appropriate in order to fairly reflect the fair market values of
          the Investment Funds and each Eligible Employee's Account. For this
          purpose, the Plan Administrator may rely upon information provided by
          the Plan Administrator or other persons believed by the Plan
          Administrator to be competent.

     (e)  Statements of Eligible Employee's Accounts.  Each Eligible Employee
          ------------------------------------------
          shall be furnished with periodic statements of his or her interest in
          the Plan, at least annually.

7.   Distributions
     -------------

     (a)  Distribution of Account Balances.  Unless the Eligible Employee has
          --------------------------------
          elected otherwise under this Section 7, distribution of the balance
          credited to an Eligible Employee's Account shall be made in a single
          sum in the January of the year following Retirement or termination of
          service:

          (1)  In the case of an Alternate Payee (as defined in Section 9(a)),
               distribution shall be made as directed in a domestic relations
               order which the Plan Administrator determines is a QDRO (as
               defined in Section 9(a)), but only as to the portion of the
               Eligible Employee's Account which the QDRO states is payable to
               the Alternate Payee.

          (2)  Any provisions of the Plan notwithstanding distribution of
               account balances must commence no later than in the January
               following the year which the Eligible Employee reaches age 72.

     (b)  Installment Distributions.  In lieu of a single sum payment, an
          -------------------------
          Eligible Employee may elect in writing and file with the Plan
          Administrator an election that payment of amounts credited to the
          Eligible Employee's Account be made in a specified number of
          approximately equal annual installments (not in excess of 10).

     (c)  Early Distributions. By filing an election with the Plan
          -------------------
          Administrator, an Eligible Employee may elect to commence distribution
          at any time other than Retirement or termination or may alter a
          previously filed election, provided that:

                                      -8-
<PAGE>

          (1)  such election or alteration is made at least one year prior to
               the earliest date that (i) Retirement or termination of the
               Eligible Employee, or (ii) the date selected for distribution to
               begin under a previously filed election; and

          (2)  such election or alteration does not provide for the receipt of
               such amounts earlier than one year from the date of the election
               or alteration.

     (d)  Death Distributions.  If an Eligible Employee dies before the entire
          -------------------
          balance of his or her Account has been distributed (whether or not the
          Eligible Employee had previously terminated employment and whether or
          not installment payments had previously commenced), the remaining
          balance of the Eligible Employee's Account shall be distributed to the
          beneficiary designated or otherwise determined in accordance with
          Section 7(g), as soon as practicable after the date of death.

     (e)  Special Incentive Stock Ownership Premiums.  Distributions
          ------------------------------------------
          attributable to Special Incentive Stock Ownership Premiums shall only
          be made in January following the year in which an Eligible Employee
          terminates employment, Retires, or dies, and shall only be made in the
          form of one or more certificates for the number of vested Special
          Incentive Stock Ownership Premium units, rounded down to the nearest
          whole share.

     (f)  Effect of Change in Eligible Employee Status.  If an Eligible Employee
          --------------------------------------------
          ceases to be an Eligible Employee, the balance credited to his or her
          Account shall continue to be credited (or debited) with appreciation,
          depreciation, earnings, gains or losses under the terms of the Plan
          and shall be distributed to him or her at the time and in the manner
          set forth in this Section 7; provided, however, that if an Eligible
          Employee terminates employment with an Employer other than by reason
          of Retirement, the entire balance credited to his or her Account shall
          be distributed in a lump sum cash payment in January of the year
          following the year of termination of employment. Anything to the
          contrary notwithstanding, the Plan Administrator, in its sole
          discretion, may authorize an accelerated distribution of the balance
          credited to his or her Account in the form of a lump sum cash payment
          as of any earlier date.

     (g)  Payments to Incompetents.  If any individual to whom a benefit is
          ------------------------
          payable under the Plan is a minor or if the Plan Administrator
          determines that any individual to whom a benefit is payable under the
          Plan is incompetent to receive such payment or to give a valid release
          therefor, payment shall be made to the guardian, committee, or other
          representative of the estate of such individual which has been duly
          appointed by a court of competent jurisdiction. If no guardian,
          committee, or other representative has been appointed, payment may be
          made to any person as custodian for such individual under the
          California Uniform Transfers to Minors Act (or similar law of another
          state) or may be made to or applied to or for the benefit of the minor
          or incompetent, the incompetent's spouse, children or other
          dependents, the institution or persons maintaining the minor or
          incompetent, or any of them, in such proportions as the Plan
          Administrator from time to time shall determine; and the release of
          the person or institution receiving the payment shall be a valid and
          complete discharge of any liability of PG&E CORP with respect to any
          benefit so paid.

                                      -9-
<PAGE>

     (h)  Beneficiary Designations.  Each Eligible Employee may designate, in a
          ------------------------
          signed writing delivered to the Plan Administrator, on such form as it
          may prescribe, one or more beneficiaries to receive any distribution
          which may become payable under the Plan as the result of the Eligible
          Employee's death. An Eligible Employee may designate different
          beneficiaries at any time by delivering a new designation in like
          manner. Any designation shall become effective only upon its receipt
          by the Plan Administrator, and the last effective designation received
          by the Plan Administrator shall supersede all prior designations. If
          an Eligible Employee dies without having designated a beneficiary or
          if no beneficiary survives the Eligible Employee, the Eligible
          Employee's Account shall be payable to the beneficiary or
          beneficiaries designated or otherwise determined under the RSP.

     (i)  Undistributable Accounts.  Each Eligible Employee and (in the event of
          ------------------------
          death) his or her beneficiary shall keep the Plan Administrator
          advised of his or her current address. If the Plan Administrator is
          unable to locate the Eligible Employee or beneficiary to whom an
          Eligible Employee's Account is payable under this Section 7, the
          Eligible Employee's Account shall be frozen as of the date on which
          distribution would have been completed in accordance with this Section
          7, and no further appreciation, depreciation, earnings, gains or
          losses shall be credited (or debited) thereto. PG&E CORP shall have
          the right to assign or transfer the liability for payment of any
          undistributable Account to the Eligible Employee's former Employer (or
          any successor thereto).

     (j)  Plan Administrator Discretion.  Within the specific time periods
          -----------------------------
          described in this Section 7, the Plan Administrator shall have sole
          discretion to determine the specific timing of the payment of any
          Account balance under the Plan.

8.   Distribution Due to Unforeseeable Emergency
     -------------------------------------------

     A participant may request a distribution due to an unforseeable emergency
     by submitting a written request to the Plan Administrator.  The Plan
     Administrator shall have the authority to require such evidence as it deems
     necessary to determine if a distribution is warranted.  If an application
     for a hardship distribution due to an unforeseeable emergency is approved,
     the distribution shall be payable in a method determined by the Plan
     Administrator as soon as possible after approval of such distribution.  A
     participant who has commenced receiving installment payments under the Plan
     may request acceleration of such payments in the event of an unforeseeable
     emergency.  The Administrator may permit accelerated payments to the extent
     such accelerated payment does not exceed the amount necessary to meet the
     emergency.

9.   Domestic Relations Orders
     -------------------------

     (a)  Qualified Domestic Relations Orders.  The Plan Administrator shall
          -----------------------------------
          establish written procedures for determining whether a domestic
          relations order purporting to dispose of any portion of an Eligible
          Employee's Account is a qualified domestic relations order (within the
          meaning of Section 414(p) of the Code) (a "QDRO").
                                                     ----

                                      -10-
<PAGE>

          (1)  No Payment Unless a QDRO. No payment shall be made to any person
               designated in a domestic relations order (an "Alternate Payee")
                                                             ---------------
               until the Plan Administrator (or a court of competent
               jurisdiction reversing an initial adverse determination by the
               Plan Administrator) determines that the order is a QDRO. Payment
               shall be made to each Alternate Payee as specified in the QDRO.

          (2)  Time of Payment.  Payment may be made to an Alternate Payee in
               the form of a lump sum, at the time specified in the QDRO, but no
               earlier than as soon as practicable following the date the QDRO
               determination is made.

          (3)  Hold Procedures.  Notwithstanding any contrary Plan provision,
               prior to the receipt of a domestic relations order, the Plan
               Administrator may, in its sole discretion, place a hold upon all
               or a portion of an Eligible Employee's Account for a reasonable
               period of time (as determined by the Plan Administrator) if the
               Plan Administrator receives notice that (a) a domestic relations
               order is being sought by the Eligible Employee, his or her
               spouse, former spouse, child or other dependent, and (b) the
               Eligible Employee's Account is a source of the payment under such
               domestic relations order. For purposes of this Section 9(a)(3), a
               "hold" means that no withdrawals, distributions, or investment
                ----
               transfers may be made with respect to an Eligible Employee's
               Account. If the Plan Administrator places a hold upon an Eligible
               Employee's Account pursuant to this Section 9(a)(3), it shall
               inform the Eligible Employee of such fact.

10.  Vesting
     -------

     Except as provided in Section 4(d), an Eligible Employee's interest in his
     or her Account at all times shall be 100 percent vested and nonforfeitable.

11.  Administration of the Plan
     --------------------------

     (a)  Plan Administrator.  The Employee Benefit Committee of PG&E CORP is
          ------------------
          hereby designated as the administrator of the Plan (within the meaning
          of Section 3(16)(A) of ERISA). The Plan Administrator delegates to the
          Senior Human Resource Officer for PG&E CORP, or his or her designee,
          the authority to carry out all duties and responsibilities of the Plan
          Administrator under the Plan. The Plan Administrator shall have the
          authority to control and manage the operation and administration of
          the Plan.

     (b)  Powers of Plan Administrator.  The Plan Administrator shall have all
          ----------------------------
          discretion and powers necessary to supervise the administration of the
          Plan and to control its operation in accordance with its terms,
          including, but not by way of limitation, the power to interpret the
          provisions of the Plan and to determine, in its sole discretion, any
          question arising under, or in connection with the administration or
          operation of, the Plan.

                                      -11-
<PAGE>

     (c)  Decisions of Plan Administrator.  All decisions of the Plan
          -------------------------------
          Administrator and any action taken by it in respect of the Plan and
          within the powers granted to it under the Plan shall be conclusive and
          binding on all persons and shall be given the maximum deference
          permitted by law.

12.  Funding
     -------

     All amounts credited to an Eligible Employee's Account under the Plan shall
     continue for all purposes to be a part of the general assets of PG&E CORP.
     The interest of the Eligible Employee in his or her Account, including his
     or her right to distribution thereof, shall be an unsecured claim against
     the general assets of PG&E CORP.  While PG&E CORP may choose to invest a
     portion of its general assets in investments identical or similar to those
     selected by Eligible Employees for purposes of determining the amounts to
     be credited (or debited) to their Accounts, nothing contained in the Plan
     shall give any Eligible Employee or beneficiary any interest in or claim
     against any specific assets of PG&E CORP.

13.  Modification or Termination of Plan
     -----------------------------------

     (a)  Employers' Obligations Limited.  The Plan is voluntary on the part of
          ------------------------------
          the Employers, and the Employers do not guarantee to continue the
          Plan. PG&E CORP at any time may, by appropriate amendment of the Plan,
          suspend Matching Employer Contributions and/or Basic Employer
          Contributions or may discontinue Matching Employer Contributions
          and/or Basic Employer Contributions, with or without cause.

     (b)  Right to Amend or Terminate.  The Board of Directors, acting through
          ---------------------------
          its Nominating and Compensation Committee, reserves the right to
          alter, amend, or terminate the Plan, or any part thereof, in such
          manner as it may determine, for any reason whatsoever.

          (1)  Limitations.  Any alteration, amendment, or termination shall
               take effect upon the date indicated in the document embodying
               such alteration, amendment, or termination, provided that no such
               alteration or amendment shall divest any portion of an Account
               that is then vested under the Plan.

     (c)  Effect of Termination.  If the Plan is terminated, the balances
          ---------------------
          credited to the Accounts of the Eligible Employees affected by such
          termination shall be distributed to them at the time and in the manner
          set forth in Section 7; provided, however, that the Plan
          Administrator, in its sole discretion, may authorize accelerated
          distribution of Eligible Employees' Accounts as of any earlier date.

14.  General Provisions
     ------------------

     (a)  Inalienability.  Except to the extent otherwise directed by a domestic
          --------------
          relations order which the Plan Administrator determines is a QDRO (as
          defined in Section 9(a) or mandated by applicable law, in no event may
          either an Eligible Employee, a former Eligible Employee or his or her
          spouse, beneficiary or estate sell, transfer, anticipate, assign,
          hypothecate, or otherwise dispose of any right or interest under the
          Plan; and such rights and interests shall not at any time be subject
          to the claims of creditors nor be liable to attachment, execution, or
          other legal process.

                                      -12-
<PAGE>

     (b)  Rights and Duties.  Neither the Employers nor the Plan Administrator
          -----------------
          shall be subject to any liability or duty under the Plan except as

          Contributions, nor any action of any Employer or Plan Administrator,
          shall be held or construed to confer upon any individual any right to

          be done and performed by any officer or employee of the Employer who
          is thereunto duly authorized by the board of directors of the
          Employer.

     (f)  Severability.  If any provision of the Plan is held invalid or
          ------------
          unenforceable, its invalidity or unenforceability shall not affect any
          other provisions of the Plan, and the Plan shall be construed and
          enforced as if such provision had not been included.

                               PG&E CORPORATION
                          LONG-TERM INCENTIVE PROGRAM
                (As amended effective as of February 16, 2000)


1.   Purpose of the Program
     ----------------------

     This is the controlling and definitive statement of the PG&E Corporation
     Long-Term Incentive Program, as amended and restated herein (hereinafter
     called the PROGRAM/1/).  The purpose of the PROGRAM is to advance the
     interests of the CORPORATION by providing ELIGIBLE PARTICIPANTS with
     financial incentives to promote the success of its long-term (five to ten
     years) business objectives, and to increase their proprietary interest in
     the success of the CORPORATION.  It is the intent of the CORPORATION to
     reward those ELIGIBLE PARTICIPANTS who have a significant impact on
     improved long-term corporate achievements.  Inasmuch as the PROGRAM is
     designed to encourage financial performance and to improve the value of
     shareholders' investment in PG&E CORPORATION, the costs of the PROGRAM will
     be funded from corporate earnings.

2.   Program Administration
     ----------------------

     The PROGRAM shall be administered by the COMMITTEE, except that the BOARD
     OF DIRECTORS shall administer the PROGRAM with respect to grants of
     INCENTIVE AWARDS TO NON-EMPLOYEE DIRECTORS.  The BOARD OF DIRECTORS may at
     any time revest authority to administer the PROGRAM in all respects in the
     BOARD OF DIRECTORS.  Subject to the provisions of the PROGRAM, the
     COMMITTEE or the BOARD OF DIRECTORS, as the case may be, shall have full
     and final authority, in its sole discretion:

     (a)  to determine the ELIGIBLE PARTICIPANTS to whom INCENTIVE AWARDS shall
          be granted and the number of shares of COMMON STOCK to be awarded
          under each INCENTIVE AWARD, based on the recommendation of the CHIEF
          EXECUTIVE OFFICER (except that awards to the CHIEF EXECUTIVE OFFICER
          shall be based on the recommendation of the BOARD OF DIRECTORS and
          awards to NON-EMPLOYEE DIRECTORS shall be based on the recommendation
          of the COMMITTEE);

     (b)  to determine the time or times at which INCENTIVE AWARDS shall be
          granted;

     (c)  to designate the types of INCENTIVE AWARD being granted;

_______________
/1/  Capitalized words are defined in Section 20 hereof.
<PAGE>

     (d)  to vary the OPTION vesting schedule described in the STOCK OPTION
          PLAN;

     (e)  to determine the terms and conditions, not inconsistent with the terms
          of the PROGRAM, of any INCENTIVE AWARD granted hereunder (including,
          but not limited to, the consideration and method of payment for shares
          purchased upon the exercise of an INCENTIVE AWARD, and any vesting
          acceleration or exercisability provisions in the event of a CHANGE IN
          CONTROL or TERMINATION), based in each case on such factors as the
          COMMITTEE or BOARD OF DIRECTORS shall deem appropriate;

     (f)  to approve forms of agreement for use under the PROGRAM;

     (g)  to construe and interpret the PROGRAM and any related INCENTIVE AWARD
          agreement and to define the terms employed herein and therein;

     (h)  except as provided in Section 18 hereof, to modify or amend any
          INCENTIVE AWARD or to waive any restrictions or conditions applicable
          to any INCENTIVE AWARD or the exercise or realization thereof;

     (i)  except as provided in Section 18 hereof, to prescribe, amend and
          rescind rules, regulations and policies relating to the administration
          of the PROGRAM;

     (j)  except as provided in Section 18 hereof, to suspend, terminate, modify
          or amend the PROGRAM;

     (k)  to delegate to one or more agents such administrative duties as the
          COMMITTEE or BOARD OF DIRECTORS may deem advisable, to the extent
          permitted by applicable law; and

     (l)  to make all other determinations and take such other action with
          respect to the PROGRAM and any INCENTIVE AWARD granted hereunder as
          the COMMITTEE may deem advisable, to the extent permitted by
          applicable law.

     Notwithstanding the provisions contained in the foregoing paragraph, the
     CHIEF EXECUTIVE OFFICER shall have the authority, in his sole discretion:
     (a) to grant INCENTIVE AWARDS to any ELIGIBLE PARTICIPANT who, at the time
     of the INCENTIVE AWARD grant, (i) is not an officer of the CORPORATION or a
     DIRECTOR, and (ii) if such ELIGIBLE PARTICIPANT is an EMPLOYEE, is
     receiving an annual salary which is below the level which requires approval
     by the COMMITTEE; (b) to determine the time or times at which INCENTIVE
     AWARDS shall be granted to such ELIGIBLE PARTICIPANTS; (c) to designate the
     types of INCENTIVE AWARD being granted to such ELIGIBLE

                                       2
<PAGE>

     PARTICIPANTS; and (d) to vary the OPTION vesting schedule described in the
     STOCK OPTION PLAN for the OPTIONS granted to such ELIGIBLE PARTICIPANTS;
     provided, however, that all grants of INCENTIVE AWARDS by the CHIEF
     EXECUTIVE OFFICER shall conform to the guidelines previously approved by
     the COMMITTEE.

3.   Shares of Stock Subject to the Program
     --------------------------------------

     There shall be reserved for use under the PROGRAM (subject to the
     provisions of Section 13 hereof) a total of 34,389,230 shares of COMMON
     STOCK, which shares may be authorized but unissued shares of COMMON STOCK
     or issued shares of COMMON STOCK which shall have been reacquired by PG&E
     CORPORATION.  Such shares consist of (i) 13,000,000 shares of COMMON STOCK
     originally reserved for use under the PROGRAM at the time it first became
     effective on January 1, 1992, (ii) 389,230 shares of COMMON STOCK remaining
     under the 1986 OPTION PLAN and carried over to the PROGRAM, (iii)
     10,000,000 shares of COMMON STOCK added to the PROGRAM effective as of
     January 1, 1996, and (iv) 11,000,000 shares of COMMON STOCK added to the
     PROGRAM effective as of April 21, 1999.

     If (i) any INCENTIVE AWARD expires or terminates for any reason without
     having been exercised or purchased in full, (ii) an INCENTIVE AWARD is
     surrendered in exchange for one or more other INCENTIVE AWARDS, or (iii)
     any RESTRICTED STOCK is forfeited, then, in each such case, any
     unexercised, unpurchased, surrendered or forfeited shares which were
     subject to such INCENTIVE AWARD (except shares as to which a related TANDEM
     SAR has been exercised) shall again be available for the future grant of
     INCENTIVE AWARDS under the PROGRAM (unless the PROGRAM has terminated).  In
     addition, shares may be reused or added back to the PROGRAM to the extent
     permitted by applicable law.

4.   Eligibility
     -----------

     INCENTIVE AWARDS will be granted only to ELIGIBLE PARTICIPANTS.  ISOS will
     be granted only to EMPLOYEES.  The COMMITTEE, in its sole discretion, may
     grant INCENTIVE AWARDS to an ELIGIBLE PARTICIPANT who is a resident or
     citizen of a foreign country, with such modifications as the COMMITTEE may
     deem advisable to reflect the laws, tax policy or customs of such foreign
     country.

     The PROGRAM shall not confer upon any RECIPIENT any right to continuation
     of employment, service as a DIRECTOR or consulting relationship with the
     CORPORATION; nor shall it interfere in any way with the right of the
     RECIPIENT or the CORPORATION to terminate such employment, service as a
     DIRECTOR or consulting relationship at any time, with or without cause.

                                       3
<PAGE>

5.   Designation of Incentive Awards
     -------------------------------

     At the time of the grant of each INCENTIVE AWARD under the Program, the
     COMMITTEE (or the CHIEF EXECUTIVE OFFICER, in the case of INCENTIVE AWARDS
     granted by the CHIEF EXECUTIVE OFFICER to certain ELIGIBLE PARTICIPANTS
     pursuant to Section 2 hereof, or the BOARD OF DIRECTORS, in the case of
     INCENTIVE AWARDS granted by the BOARD OF DIRECTORS to NON-EMPLOYEE
     DIRECTORS) shall determine whether such INCENTIVE AWARD is to be designated
     as an ISO, NON-QUALIFIED STOCK OPTION, SAR, DIVIDEND EQUIVALENT,
     PERFORMANCE UNIT, stock grant, RESTRICTED STOCK, LSAR, PHANTOM STOCK or
     other STOCK-BASED AWARD; provided, however, that ISOS may be granted only
     to EMPLOYEES.

     Notwithstanding such designation, to the extent that the aggregate FAIR
     MARKET VALUE (determined for each share as of the date of grant of the
     OPTION covering each share) of the shares with respect to which OPTIONS
     designated as ISOS become exercisable for the first time by any RECIPIENT
     during any calendar year exceeds $100,000, such OPTIONS shall be treated as
     NON-QUALIFIED STOCK OPTIONS.

     Any INCENTIVE AWARD may be granted alone, contingent upon, in addition to
     or in TANDEM with one or more other INCENTIVE AWARDS granted under the
     PROGRAM.  In addition, except as provided in Section 12 hereof, any
     INCENTIVE AWARD may be granted in exchange for one or more other INCENTIVE
     AWARDS.

6.   Stock Options, Tandem Stock Appreciation Rights and Tandem Dividend
     -------------------------------------------------------------------
     Equivalents
     -----------

     Except as provided in Section 9 below (relating to grants of INCENTIVE
     AWARDS to NON-EMPLOYEE DIRECTORS), the COMMITTEE, in its sole discretion,
     may grant ISOS, NON-QUALIFIED STOCK OPTIONS, TANDEM SARS and TANDEM
     DIVIDEND EQUIVALENTS to ELIGIBLE PARTICIPANTS, subject to the terms and
     conditions set forth in the STOCK OPTION PLAN attached hereto as Exhibit A.

7.   Performance Units
     -----------------

     Except as provided in Section 9 below (relating to grants of INCENTIVE
     AWARDS to NON-EMPLOYEE DIRECTORS), the COMMITTEE, in its sole discretion,
     may grant PERFORMANCE UNITS to ELIGIBLE PARTICIPANTS, subject to the terms
     and conditions set forth in the PERFORMANCE UNIT PLAN attached hereto as
     Exhibit B.

8.   Other Incentive Awards
     ----------------------

                                       4
<PAGE>

     Except as provided in Section 9 below (relating to grants of INCENTIVE
     AWARDS to NON-EMPLOYEE DIRECTORS), the COMMITTEE, in its sole discretion,
     may grant other INCENTIVE AWARDS (including, but not limited to, SARS
     granted without OPTIONS, DIVIDEND EQUIVALENTS granted without OPTIONS,
     stock grants, RESTRICTED STOCK, LSARS, PHANTOM STOCK or other STOCK-BASED
     AWARDS) to ELIGIBLE PARTICIPANTS, subject to such terms and conditions as
     the COMMITTEE shall deem appropriate.

9.   Grants of Incentive Awards to Non-Employee Directors
     ----------------------------------------------------

     NON-EMPLOYEE DIRECTORS will only be eligible to be granted DIRECTOR
     RESTRICTED STOCK, PHANTOM STOCK and NON-QUALIFIED STOCK OPTIONS in
     accordance with, and subject to the terms and conditions contained in, the
     NON-EMPLOYEE DIRECTOR STOCK INCENTIVE PLAN RULES attached hereto as Exhibit
     C.

10.  Termination of Employment or Relationship with the CORPORATION
     --------------------------------------------------------------

     The COMMITTEE may, in its sole discretion, establish terms and conditions
     pertaining to the effect of TERMINATION on INCENTIVE AWARDS granted to a
     RECIPIENT prior to TERMINATION, to the extent permitted by applicable law.

11.  Tax Withholding
     ---------------

     When a RECIPIENT incurs tax liability in connection with the exercise of an
     INCENTIVE AWARD or the receipt of shares of COMMON STOCK pursuant to an
     INCENTIVE AWARD, which tax liability is subject to tax withholding under
     applicable tax laws, and the RECIPIENT is obligated to pay the CORPORATION
     an amount required to be withheld under applicable tax laws, the RECIPIENT
     may satisfy the withholding tax obligation by (i) electing to have the
     CORPORATION withhold such amount from his or her current compensation
     through payroll deductions, or (ii) making a direct payment to the
     CORPORATION in cash or by check.

     The COMMITTEE may, in its sole discretion, permit a RECIPIENT to satisfy
     all or part of his or her withholding tax obligations by having the
     CORPORATION withhold from the shares to be issued to the RECIPIENT that
     number of shares having a FAIR MARKET VALUE equal to the amount required to
     be withheld determined on the date when taxes otherwise would be withheld
     in cash.  The payment of withholding taxes in this manner, if permitted by
     the COMMITTEE, shall be subject to such restrictions as the COMMITTEE may
     impose, including any restrictions required by rules of the Securities and
     Exchange Commission.

                                       5
<PAGE>

12.  Replacement of Grants
     ---------------------

     The COMMITTEE may, in its sole discretion, offer a RECIPIENT (other than
     NON-EMPLOYEE DIRECTORS) the option of surrendering an unexercised OPTION or
     other INCENTIVE AWARD in exchange for another INCENTIVE AWARD of the same
     type or for a different type of INCENTIVE AWARD; provided, however, that no
     OPTION or INCENTIVE AWARD may be exchanged for a new OPTION or INCENTIVE
     AWARD having an OPTION PRICE or purchase price that is lower than the
     OPTION PRICE or purchase price of the original OPTION or INCENTIVE AWARD.

13.  Deferral of Payments
     --------------------

     The COMMITTEE may, in its sole discretion, approve a RECIPIENT'S deferral
     of any cash payments which may become due under the PROGRAM.  Such
     deferrals shall be subject to any conditions, restrictions or requirements
     as the COMMITTEE may determine.

14.  Adjustments Upon Changes in Number or Value of Shares of Common Stock
     ---------------------------------------------------------------------

     If there are any changes in the number or value of shares of COMMON STOCK
     by reason of stock dividends, stock splits, reverse stock splits,
     recapitalizations, mergers, consolidations or other events that materially
     increase or decrease the number or value of issued and outstanding shares
     of COMMON STOCK, the COMMITTEE may make such adjustments as it shall deem
     appropriate, in order to prevent dilution or enlargement of rights.

15.  Non-Transferability of Incentive Awards
     ---------------------------------------

     An INCENTIVE AWARD shall not be transferable by the RECIPIENT otherwise
     than by will or the laws of descent and distribution, or pursuant to a
     qualified domestic relations order as defined by the CODE, Title I of ERISA
     or the rules thereunder.  During the lifetime of the RECIPIENT, an
     INCENTIVE AWARD may be exercised only by the RECIPIENT or by an alternate
     payee under a qualified domestic relations order.

16.  Change in Control
     -----------------

     Upon the occurrence of a CHANGE IN CONTROL (as defined below):

     (a)  Any time periods relating to the exercise or realization of any
          INCENTIVE AWARD granted hereunder shall be accelerated so that such
          INCENTIVE AWARD may be immediately exercised or realized in full;

<PAGE>

     INCENTIVE AWARD or the issue or purchase of shares thereunder, such

18.  Amendment and Termination of the Program and Incentive Awards

     The BOARD OF DIRECTORS or the COMMITTEE may at any time suspend, terminate,
     modify or amend the PROGRAM in any respect; provided, however, that to the
     extent necessary and desirable to comply with Section 422 of the CODE (or
     any other applicable law or regulation, including the requirements of any
     stock exchange on which the COMMON STOCK is listed or quoted), shareholder
     approval of any PROGRAM amendment shall be obtained in such a manner and to
     such a degree as is required by the applicable law or regulation.

     No suspension, termination, modification or amendment of the PROGRAM may,
     without the consent of the RECIPIENT, adversely affect his or her rights
     under INCENTIVE AWARDS theretofore granted to such RECIPIENT.  In the event
     of amendments to the CODE or applicable rules or regulations relating to
     ISOS subsequent to the date hereof, the CORPORATION may amend the PROGRAM,
     and the CORPORATION and RECIPIENTS holding OPTION agreements may agree to
     amend outstanding OPTION agreements, to conform to such amendments.

     The BOARD OF DIRECTORS or COMMITTEE may make such amendments or
     modifications in the terms and conditions of any INCENTIVE AWARD as it may
     deem advisable, or cancel or annul any grant of an INCENTIVE AWARD;
     provided, however, that no such amendment, modification, cancellation or
     annulment may, without the consent of the RECIPIENT, adversely affect his
     or her rights under such INCENTIVE AWARD; and provided further the BOARD OF
     DIRECTORS or COMMITTEE may not reduce the OPTION PRICE or purchase price of
     any OPTION or INCENTIVE AWARD below the original OPTION PRICE or purchase
     price.

     Notwithstanding the foregoing, the BOARD OF DIRECTORS or COMMITTEE reserves
     the right, in its sole discretion, to (i) convert any outstanding ISOS to
     NON-QUALIFIED STOCK OPTIONS, (ii) to require a RECIPIENT to forfeit any
     unexercised or unpurchased INCENTIVE AWARDS, any shares received or
     purchased pursuant to an INCENTIVE AWARD, or any gains realized by virtue
     of the receipt of an INCENTIVE AWARD in the event that such RECIPIENT
     competes against the CORPORATION, and (iii) to cancel or annul any grant of
     an INCENTIVE AWARD in the event of a RECIPIENT'S TERMINATION FOR CAUSE.
     For purposes of the PROGRAM, "TERMINATION FOR CAUSE" shall include, but not
     be limited to, termination because of dishonesty, criminal offense or
     violation of a work rule, and shall be determined by, and in the sole
     discretion of, the BOARD OF DIRECTORS or COMMITTEE.

     shares of COMMON STOCK which shall have been reacquired by PG&E
     CORPORATION.

     If any OPTION expires or terminates for any reason without having been
     exercised in full, then any unexercised, shares which were subject to such
     OPTION (except shares as to which a related TANDEM SAR has been exercised)
     shall again be available for the future grant of OPTIONS under the PLAN
     (unless the PLAN has terminated).  In addition, shares may be reused or
     added back to the PLAN to the extent permitted by applicable law.

4.   Eligibility
     -----------

     OPTIONS will be granted only to ELIGIBLE PARTICIPANTS.  ISOS will be
     granted only to EMPLOYEES.  The COMMITTEE, in its sole discretion, may
     grant OPTIONS to an ELIGIBLE PARTICIPANT who is a resident or citizen of a
     foreign country, with such modifications as the COMMITTEE may deem
     advisable to reflect the laws, tax policy or customs of such foreign
     country.

     The PLAN shall not confer upon any OPTIONEE any right to continuation of
     employment, service as a DIRECTOR or consulting relationship with the
     CORPORATION; nor shall it interfere in any way with the right of the
     OPTIONEE or the CORPORATION to terminate such employment, service as a
     DIRECTOR or consulting relationship at any time, with or without cause.

5.   Limitation on Options and SARs Awarded to Any Eligible Participant
     ------------------------------------------------------------------

     The aggregate number of shares of COMMON STOCK with respect to which any
     ELIGIBLE PARTICIPANT may be granted OPTIONS and SARS under the PLAN during
     any calendar year shall in no event exceed two percent (2%) of the total
     number of shares reserved for use under the PLAN.

                                       16

6.   Designation of Options
     ----------------------

     At the time of the grant of each OPTION under the PLAN, the COMMITTEE (or
     the CHIEF EXECUTIVE OFFICER, in the case of OPTIONS granted by the CHIEF
     EXECUTIVE OFFICER to certain ELIGIBLE PARTICIPANTS pursuant to Section 2
     hereof) shall determine whether such OPTION is to be designated as an ISO
     or a NON-QUALIFIED STOCK OPTION; provided, however, that ISOS may be
     granted only to EMPLOYEES.

     Notwithstanding such designation, to the extent that the aggregate FAIR
     MARKET VALUE (determined for each share as of the date of grant of the
     OPTION covering each share) of the shares with respect to which OPTIONS
     designated as ISOS become exercisable for the first time by any OPTIONEE
     during any calendar year exceeds $100,000, such OPTIONS shall be treated as
     NON-QUALIFIED STOCK OPTIONS.

7.   Option Price
     ------------

     The OPTION PRICE of the COMMON STOCK under each OPTION issued shall be the
     FAIR MARKET VALUE of the COMMON STOCK on the date of grant.

8.   Stock Appreciation Rights
     -------------------------

     At the discretion of the COMMITTEE, an OPTION may be granted with or
     without a TANDEM SAR which permits the OPTIONEE to surrender unexercised an
     OPTION or portion thereof and to receive in exchange a payment having a
     value equal to the difference between (x) the FAIR MARKET VALUE of the
     COMMON STOCK covered by the surrendered portion of the OPTION on the date
     the SAR is exercised and (y) the OPTION PRICE for such COMMON STOCK.  The
     SAR is subject to the same terms and conditions as the related OPTION,
     except that (i) the SAR may be exercised only when there is a positive
     spread (i.e., when the FAIR MARKET VALUE of the COMMON STOCK subject to the
     OPTION exceeds the OPTION PRICE), (ii) in accordance with Section 9 hereof,
     payment of the DEA (if any) to the OPTIONEE may be restricted, and (iii) if
     the OPTIONEE is a SECTION 16 OFFICER, DIRECTOR or other person whose
     transactions in the COMMON STOCK are subject to Section 16(b) of the
     EXCHANGE ACT, the SAR may be exercised only during the period beginning on
     the third (3rd) business day following the date of release of the
     CORPORATION's quarterly or annual statement of earnings and ending on the
     twelfth (12th) business day following such date.  Upon the exercise of a
     SAR, the number of shares subject to exercise under the related OPTION
     shall be automatically reduced by the number of shares represented by the
     OPTION or portion thereof surrendered.  No payment will be required from
     the OPTIONEE upon the exercise of a SAR, except that any amount necessary
     to satisfy applicable federal, state or local tax requirements shall be
     withheld.

                                       17
<PAGE>

9.   Dividend Equivalent Account
     ---------------------------

     At the discretion of the COMMITTEE, an OPTION may be granted with or
     without TANDEM DIVIDEND EQUIVALENTS.  When an OPTION is granted with TANDEM
     DIVIDEND EQUIVALENTS, a Dividend Equivalent Account ("DEA") shall be
     established for the OPTIONEE.  This DEA shall be credited quarterly on each
     dividend record date with dividends which would have been paid on the
     COMMON STOCK subject to the unexercised portion of the OPTION (including
     any portion which has not yet vested on the record date), if such portion
     had been exercised.  Except as provided in Section 12(d) hereof, at the
     time the OPTION or any related SAR is exercised, the OPTIONEE shall receive
     all funds which have accumulated in the DEA with respect to the shares of
     COMMON STOCK for which the OPTION or SAR is being exercised; provided,
     however, that if the OPTIONEE exercises a SAR, such DEA funds shall only be
     paid to the OPTIONEE if (i) the percentage increase in the FAIR MARKET
     VALUE of the COMMON STOCK over the OPTION PRICE averages at least five
     percent (5%) per year for the first five (5) years after the grant, or (ii)
     in the case of OPTIONS held for longer than five (5) years from the date of
     grant, such FAIR MARKET VALUE has increased by at least twenty-five percent
     (25%) over the OPTION PRICE.

10.  Terms of Options
     ----------------

     The term of each ISO shall be for ten (10) years from the date of grant,
     subject to earlier termination as provided in Section 12 hereof.  The term
     of each NON-QUALIFIED STOCK OPTION shall be ten (10) years and one (1) day
     from the date of grant, subject to earlier termination as provided in
     Section 12 hereof.  Any provision of the PROGRAM to the contrary
     notwithstanding, no OPTION shall be exercised after the time limitations
     stated in this Section 10.

11.  Limitations on Exercise
     -----------------------

     (a)  Each OPTION granted under the PROGRAM shall become exercisable and
          vested only to the following extent:  (i) up to one-third (1/3) of the
          OPTIONS granted may be exercised on or after the second (2nd)
          anniversary of the date of grant; (ii) up to two-thirds (2/3) of the
          OPTIONS granted may be exercised on or after the third (3rd)
          anniversary of the date of grant; and (iii) up to one hundred percent
          (100%) of the OPTIONS granted may be exercised on or after the fourth
          (4th) anniversary of the date of grant.

     (b)  No OPTION under the PROGRAM designated by the COMMITTEE as an ISO and
          granted before January 1, 1987 may be exercised while there is
          outstanding in the hands of the OPTIONEE any ISO which was granted

                                       18
<PAGE>

          before the granting of the ISO hereunder sought to be exercised.  For
          this purpose an ISO shall be treated as outstanding until such OPTION
          is (i) exercised in full, (ii) surrendered in full by exercising SARS
          pursuant to Section 8 hereof, or (iii) rendered void by reason of
          lapse of time.

12.  Termination of Employment or Relationship with the CORPORATION
     --------------------------------------------------------------

     (a)  In the event of a TERMINATION by reason of a discharge or TERMINATION
          FOR CAUSE, any unexercised OPTIONS theretofore granted to an OPTIONEE
          under the PROGRAM shall forthwith terminate.

     (b)  In the event of a TERMINATION by reason of RETIREMENT, all OPTIONS
          held by the OPTIONEE, to the extent that such OPTIONS have not
          previously expired or been exercised, shall become fully exercisable
          and vested, notwithstanding the provisions of Section 11(a) hereof,
          and the OPTIONEE shall have the right to exercise such OPTIONS in full
          at any time within their respective terms or within five (5) years
          after such RETIREMENT, whichever is shorter.  This five-year period
          shall be extended if an OPTIONEE remains on the BOARD OF DIRECTORS
          after RETIREMENT.  In such case, the OPTIONS may be exercised as long
          as the OPTIONEE remains a DIRECTOR and for a period of six (6) months
          thereafter, or within five (5) years after RETIREMENT, whichever is
          longer; provided, however, that no OPTION may be exercised after the
          expiration of its term.  To the extent any ISO held by the OPTIONEE is
          exercised after the expiration of three (3) months after such
          TERMINATION, the exercise will be deemed to involve the exercise of a
          NON-QUALIFIED STOCK OPTION.

     (c)  In the event of a TERMINATION by reason of disability or death, all
          OPTIONS held by the OPTIONEE, to the extent that such OPTIONS have not
          previously expired or been exercised, shall become fully exercisable
          and vested, notwithstanding the provisions of Section 11(a) hereof,
          and the OPTIONEE (or the OPTIONEE'S estate or a person who acquired
          the right to exercise such OPTIONS by bequest or inheritance) shall
          have the right to exercise such OPTIONS at any time within their
          respective terms or within one (1) year after the date of such
          TERMINATION, whichever is shorter.  The term "disability" shall, for
          the purposes of the PLAN, be defined in Section 22(e)(3) of the CODE.

     (d)  In the event of a TERMINATION by reason of a divestiture or change in
          control of a subsidiary of PG&E CORPORATION, which divestiture or
          change in control results in such subsidiary no longer qualifying as a
          subsidiary corporation under Section 424(f) of the CODE, all OPTIONS
          held by the OPTIONEE, to the extent that such OPTIONS have not
          previously expired or been exercised, shall become fully exercisable
          and

                                       19
<PAGE>

          vested, notwithstanding the provisions of Section 11(a) hereof, and
          the OPTIONEE shall have the right to exercise such OPTIONS in full at
          any time within their respective terms or within three (3) years after
          such TERMINATION, whichever is shorter. This three-year period shall
          be extended if an OPTIONEE remains on the BOARD OF DIRECTORS after
          such TERMINATION. In such case, the OPTIONS may be exercised as long
          as the OPTIONEE remains a DIRECTOR and for a period of six (6) months
          thereafter, or within three (3) years after such TERMINATION,
          whichever is longer; provided, however, that no OPTION may be
          exercised after the expiration of its term. To the extent any ISO held
          by the OPTIONEE is exercised after the expiration of three (3) months
          after such TERMINATION, the exercise will be deemed to involve the
          exercise of a NON-QUALIFIED STOCK OPTION.

     (e)  In the event of a TERMINATION within one year after a CHANGE IN
          CONTROL of the CORPORATION (other than a TERMINATION covered by
          clauses (a), (b), or (c) above), OPTIONEE shall have the right to
          exercise OPTIONS which OPTIONEE then holds (which OPTIONS will have
          been accelerated previously in accordance with Section 16 below), to
          the extent that such OPTIONS have not previously expired or been
          exercised, in full at any time within their respective terms or within
          three (3) years after such TERMINATION, whichever is shorter.  This
          three-year period shall be extended if an OPTIONEE remains on the
          BOARD OF DIRECTORS after such TERMINATION.  In such case, the OPTIONS
          may be exercised as long as the OPTIONEE remains a DIRECTOR and for a
          period of six (6) months thereafter, or within three (3) years after
          such TERMINATION, whichever is longer; provided, however, that no
          OPTION may be exercised after the expiration of its term.  To the
          extent any ISO held by the OPTIONEE is exercised after the expiration
          of three (3) months after such TERMINATION, the exercise will be
          deemed to involve the exercise of a NON-QUALIFIED STOCK OPTION.

     (f)  In the event of a TERMINATION for any reason other than those
          specified in subparagraphs (a) through (e) above, (i) any unexercised
          OPTION or OPTIONS granted under the PROGRAM shall be deemed canceled
          and terminated forthwith, except that the OPTIONEE may exercise any
          unexercised OPTIONS theretofore granted which are otherwise
          exercisable and vested within the provisions of Section 11(a) hereof,
          during the balance of their respective terms or within thirty (30)
          days of such TERMINATION, whichever is shorter, and (ii) the DEA (if
          any) shall not be credited with any dividends paid after the date of
          such TERMINATION.

                                       20
<PAGE>

     (g)  Notwithstanding the provisions of subparagraphs (a) through (f) above,
          the COMMITTEE may, in its sole discretion, establish different terms
          and conditions pertaining to the effect of TERMINATION, to the extent
          permitted by applicable federal and state law.

13.  Payment for Shares Upon Exercise of Options
     -------------------------------------------

     The exercise of any OPTION shall be contingent upon receipt by the
     CORPORATION of (i) cash (including any DEA funds payable to the OPTIONEE in
     connection with the exercise of such OPTION), (ii) check, (iii) shares of
     COMMON STOCK, (iv) an executed exercise notice together with irrevocable
     instructions to a broker to either sell the shares subject to the OPTION or
     hold such shares as collateral for a margin loan and to promptly deliver to
     the CORPORATION the amount of sale or loan proceeds required to pay the
     OPTION PRICE, (v) any combination of the foregoing in an amount equal to
     the full OPTION PRICE of the shares being purchased, or (vi) such other
     consideration and method of payment, other than a note from the OPTIONEE,
     as the COMMITTEE, in its sole discretion, may allow (which, in the case of
     an ISO shall be determined at the time of grant), to the extent permitted
     by applicable law.  For purposes of this paragraph, shares of COMMON STOCK
     that are delivered in payment of the OPTION PRICE must have been previously
     owned by the OPTIONEE for a minimum of one year, and shall be valued at
     their FAIR MARKET VALUE as of the date of the exercise of the OPTION.  The
     CORPORATION shall not make loans to any OPTIONEE for the purpose of
     exercising OPTIONS.

14.  Adjustments Upon Changes in Number or Value of Shares of Common Stock
     ---------------------------------------------------------------------

     If there are any changes in the number or value of shares of COMMON STOCK
     by reason of stock dividends, stock splits, reverse stock splits,
     recapitalizations, mergers, consolidations or other events that materially
     increase or decrease the number or value of issued and outstanding shares
     of COMMON STOCK, the COMMITTEE may make such adjustments as it shall deem
     appropriate, in order to prevent dilution or enlargement of rights.

15.  Non-Transferability of Options
     ------------------------------

     An OPTION shall not be transferable by the OPTIONEE otherwise than by will
     or the laws of descent and distribution, or pursuant to a qualified
     domestic relations order as defined by the CODE, Title I of ERISA or the
     rules thereunder.  During the lifetime of the OPTIONEE, an OPTION may be
     exercised only by the OPTIONEE or by an alternate payee under a qualified
     domestic relations order.

16.  Change in Control
     -----------------

                                       21
<PAGE>

     Upon the occurrence of a CHANGE IN CONTROL (as defined below), any time
     periods relating to the exercise of any OPTION granted hereunder shall be
     accelerated so that such OPTION may be immediately exercised in full.

     A "CHANGE IN CONTROL" shall be deemed to have occurred if:

     (a)  any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
          the EXCHANGE ACT, but excluding any benefit plan for EMPLOYEES or any
          trustee, agent or other fiduciary for any such plan acting in such
          person's capacity as such fiduciary), directly or indirectly, becomes
          the beneficial owner of securities of PG&E CORPORATION representing
          twenty percent (20%) or more of the combined voting power of the
          CORPORATION's then outstanding securities;

     (b)  during any two consecutive years, individuals who at the beginning of
          such a period constitute the BOARD OF DIRECTORS cease for any reason
          to constitute at least a majority of the BOARD OF DIRECTORS, unless
          the election, or the nomination for election by the shareholders of
          the CORPORATION, of each new DIRECTOR was approved by a vote of at
          least two-thirds (2/3) of the DIRECTORS then still in office who were
          DIRECTORS at the beginning of the period; or

     (c)  the shareholders of the CORPORATION shall have approved (i) any
          consolidation or merger of the CORPORATION other than a merger or
          consolidation which would result in the voting securities of the
          CORPORATION outstanding immediately prior thereto continuing to
          represent (either by remaining outstanding or by being converted into
          voting securities of the surviving entity or any parent of such
          surviving entity) at least 70 percent of the Combined Voting Power of
          the CORPORATION, such surviving entity or the parent of such surviving
          entity outstanding immediately after the merger or consolidation; (ii)
          any sale, lease, exchange or other transfer (in one transaction or a
          series of related transactions) of all or substantially all of the
          assets of the CORPORATION, or (iii) any plan or proposal for the
          liquidation or dissolution of the CORPORATION.  For purposes of this
          paragraph, the term Combined Voting Power shall mean the combined
          voting power of the CORPORATION's or other relevant entity's then
          outstanding voting securities.

                                       22
<PAGE>

17.  Listing and Registration of Shares
     ----------------------------------

     Each OPTION shall be subject to the requirement that if at any time the
     COMMITTEE shall determine, in its discretion, that the listing,
     registration or qualification of the shares covered thereby under any
     securities exchange or under any state or federal law or the consent or
     approval of any governmental regulatory body, including the California
     Public Utilities Commission, is necessary or desirable as a condition of,
     or in connection with, the granting of such OPTION or the issue or purchase
     of shares thereunder, such OPTION may not be exercised in whole or in part
     unless and until such listing, registration, qualification, consent or
     approval shall have been effected or obtained free of any conditions not
     acceptable to the COMMITTEE.

18.  Amendment and Termination of the Plan and Options
     -------------------------------------------------

     The BOARD OF DIRECTORS or the COMMITTEE may at any time suspend, terminate,
     modify or amend the PLAN in any respect; provided, however, that, to the
     extent necessary and desirable to comply with Section 422 of the CODE (or
     any other applicable law or regulation, including the requirements of any
     stock exchange on which the COMMON STOCK is listed or quoted), shareholder
     approval of any PLAN amendment shall be obtained in such a manner and to
     such a degree as is required by the applicable law or regulation.

     No suspension, termination, modification or amendment of the PLAN may,
     without the consent of the OPTIONEE, adversely affect his or her rights
     under OPTIONS theretofore granted to such OPTIONEE.  In the event of
     amendments to the CODE or applicable rules or regulations relating to ISOS
     subsequent to the date hereof, the CORPORATION may amend the PLAN, and the
     CORPORATION and OPTIONEES holding OPTION agreements may agree to amend
     outstanding OPTION agreements, to conform to such amendments.

     The COMMITTEE may make such amendments or modifications in the terms and
     conditions of any OPTION as it may deem advisable, or cancel or annul any
     grant of an OPTION; provided, however, that no such amendment,
     modification, cancellation or annulment may, without the consent of the
     OPTIONEE, adversely affect his or her rights under such OPTION; and
     provided further the COMMITTEE may not reduce the OPTION PRICE or purchase
     price of any OPTION or OPTION below the original OPTION PRICE or purchase
     price.

     Notwithstanding the foregoing, the COMMITTEE reserves the right, in its
     sole discretion, to (i) convert any outstanding ISOS to NON-QUALIFIED STOCK
     OPTIONS, (ii) to require a OPTIONEE to forfeit any unexercised or
     unpurchased OPTIONS, any shares received or purchased pursuant to an
     OPTION, or any gains realized by virtue of the receipt of an OPTION in the
     event that such OPTIONEE competes against the CORPORATION, and (iii) to
     cancel or annul any grant of an

                                       23
<PAGE>

     OPTION in the event of a OPTIONEE'S TERMINATION FOR CAUSE. For purposes of
     the PROGRAM, "TERMINATION FOR CAUSE" shall include, but not be limited to,
     termination because of dishonesty, criminal offense or violation of a work
     rule, and shall be determined by, and in the sole discretion of, the
     COMMITTEE.

19.  Effective Date of the Plan and Duration
     ---------------------------------------

     The PLAN first became effective as of January 1, 1992.  It has since been
     amended and restated.  The amended and restated PLAN became effective as of

     Electric Company at its Annual Meeting on April 17, 1996.  Effective

                                   ARTICLE II

          2.01  Prior to the beginning of each YEAR, the COMMITTEE shall
determine whether PUP UNITS will be granted for such YEAR, the ELIGIBLE
EMPLOYEES to whom PUP UNITS will be granted, and the number of PUP UNITS to be
granted to each ELIGIBLE EMPLOYEE. Employees who become ELIGIBLE EMPLOYEES after
the beginning of a YEAR shall be entitled to a prorata grant of PUP UNITS.

          2.02  At the same time that the COMMITTEE makes its determination as
to the granting of PUP UNITS, it shall also establish PERFORMANCE TARGETS.
Although it is intended that PERFORMANCE TARGETS will not change in the course
of the YEAR, the COMMITTEE reserves the right to modify or adjust a previously
set PERFORMANCE TARGET if, in its sole discretion, extraordinary events warrant
such modification or adjustment; provided, however, that no such modification or
adjustment shall increase the amount of any payment that would otherwise be due
based upon performance as measured against the original PERFORMANCE TARGET.

          2.03  Each grant of PUP UNITS shall have its own VESTING PERIOD.
Subject to modification as measured against a given YEAR's applicable
PERFORMANCE TARGET, each grant of PUP UNITS shall be payable as follows:

          a.  One-third after the end of the first YEAR of the VESTING PERIOD;

                                       29

          b.  One-third after the end of the second YEAR of the VESTING PERIOD;
and

          c.  One-third after the end of the third YEAR of the VESTING PERIOD.

          2.04  To determine the number of PUP UNITS earned, the applicable
PERFORMANCE TARGET shall be the PERFORMANCE TARGET for the YEAR in which the PUP
UNITS vest.  Performance as measured against the applicable PERFORMANCE TARGET
for a YEAR shall modify all PUP UNITS that vest at the end of such YEAR.  The
PERFORMANCE TARGETS established by the COMMITTEE may modify the number of UNITS
earned from 0% to 200% of the number of vested UNITS.

          2.05  ELIGIBLE EMPLOYEES shall receive a cash payment as soon as
practicable following the YEAR PUP UNITS vest pursuant to the schedule set forth
in Section 2.03.  The amount of the payment shall be equal to the product of the
number of PUP UNITS earned multiplied by the PRICE of STOCK.

          2.06  Each time that the CORPORATION declares a dividend on its STOCK,
an amount equal to the dividend multiplied by an ELIGIBLE EMPLOYEE's
outstanding, but unearned PUP UNITS, shall be accrued on behalf of each ELIGIBLE
EMPLOYEE.  As soon as practicable following the end of each YEAR, ELIGIBLE
EMPLOYEES shall receive a cash payment of the dividends accrued for that YEAR,

          2.07  An ELIGIBLE EMPLOYEE may elect to defer the payment of PUP UNITS
and/or dividends paid on PUP UNITS by making a timely election under the
Deferred Compensation Plan.  Deferrals of benefits payable under this Plan shall
be subject to the rules contained in the Deferred Compensation Plan governing
elections to defer and receipt of deferred amounts.

          3.01  Retirement.  Upon RETIREMENT, all outstanding PUP UNITS continue
                ----------
to be payable according to the terms of the PLAN.  Thus, the number of UNITS
eventually earned by a retired employee is still subject to modification
depending on the extent to which applicable PERFORMANCE TARGETS are met during
the YEAR preceding the January in which UNITS become payable under the schedule
of Section 2.03.  A retired employee is not entitled to receive grants of PUP
UNITS after RETIREMENT.

          3.02  Disability.  If an ELIGIBLE EMPLOYEE is both disabled and
                ----------

Disability Plan, UNITS granted prior to the date of disability shall continue to
be payable according to the terms of this PLAN.  An ELIGIBLE EMPLOYEE is not
entitled to receive grants of PUP UNITS after the date of disability as
determined under the provisions of the Long Term Disability Plan.  If an
ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE EMPLOYEE because of disability and is
not entitled to receive benefits under Pacific Gas and Electric Company's Long
Term Disability Plan, all outstanding grants of PUP UNITS become vested and
payable as soon as practicable in the YEAR following the YEAR in which the
ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE EMPLOYEE.  All of the UNITS payable
shall be subject to modification based upon performance as measured against the
PERFORMANCE TARGET for the YEAR in which the ELIGIBLE EMPLOYEE ceases to be an
ELIGIBLE EMPLOYEE.

          3.03  Death.  In the event of the death of an ELIGIBLE EMPLOYEE, all
                -----
outstanding grants of PUP UNITS held by the ELIGIBLE EMPLOYEE at the date of
death shall become vested and payable as soon as practicable in the YEAR
following the YEAR of death.  All of the UNITS payable after an ELIGIBLE
EMPLOYEE's death shall be subject to modification based upon performance as
measured against the PERFORMANCE TARGET for the YEAR in which the death of the
ELIGIBLE EMPLOYEE occurs.

          3.04  Termination.  If an ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE
                -----------
EMPLOYEE for any reason other than RETIREMENT, disability, or death, all
outstanding grants of PUP UNITS shall be canceled as of the date that the
ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE EMPLOYEE unless otherwise provided in
the PG&E Corporation Officer Severance Policy.

          3.05  Change in Control.  Upon a Change in Control as defined in the
                -----------------
PG&E Corporation Long Term Incentive Program (Program), all PUP UNITS shall
become vested and payable as soon as practicable in the YEAR following the
Change in Control in accordance with Section 16 of the Program.

persons and parties concerned.

          4.02  Amendment and Termination.  The CORPORATION may amend or
                -------------------------
terminate the PLAN at any time, provided, however, that no such amendment or

                                       31
<PAGE>

termination shall adversely affect PUP UNITS which an ELIGIBLE EMPLOYEE has
earned prior to the date of such amendment or termination. PUP UNITS outstanding
but unearned at the date of any such amendment or termination may, in the sole
discretion of the CORPORATION, be canceled, and the CORPORATION shall have no
obligation to provide a substitute benefit of lesser, equal, or greater value.

          4.03  Nonassignability of Benefits.  The benefits payable under this
                ----------------------------
PLAN or the right to receive future benefits under this PLAN may not be
anticipated, alienated, pledged, encumbered, or subject to any charge or legal
process, and if any attempt is made to do so, or a person eligible for any
benefits becomes bankrupt, the interest under the PLAN of the person affected
may be terminated by the PLAN ADMINISTRATOR which, in its sole discretion, may
cause the same to be held if applied for the benefit of one or more of the
dependents of such person or make any other disposition of such benefits that it
deems appropriate.

          4.04  No Guarantee of Employment.  Nothing contained in this PLAN
                --------------------------
shall be construed as a contract of employment between the CORPORATION or the
ELIGIBLE EMPLOYEE, or as a right of the ELIGIBLE EMPLOYEE to be continued in the
employ of the CORPORATION, to remain as an officer of the CORPORATION, or as a
limitation on the right of the CORPORATION to discharge any of its employees,
with or without cause.

          4.05  Benefits Unfunded and Unsecured.  The benefits under this PLAN
                -------------------------------
are unfunded, and the interest under this PLAN of any ELIGIBLE EMPLOYEE and such
ELIGIBLE EMPLOYEE's right to receive a distribution of benefits under this PLAN
shall be an unsecured claim against the general assets of the CORPORATION.

          4.06  Applicable Law.  All questions pertaining to the construction,
                --------------
validity, and effect of the PLAN shall be determined in accordance with the laws

          QUALIFIED STOCK OPTIONS shall be determined by dividing the Elected
          Option Value by the value of a NON-QUALIFIED STOCK OPTION to purchase
          a single share of PG&E Corporation common stock as of the first
          business day of the applicable calendar year. The per stock option
          value shall be calculated in accordance with the Black-Scholes stock
          option valuation method using the average preceding November closing
          price of PG&E Corporation stock and reducing the per option value so
          calculated by twenty percent. The resulting number of NON-QUALIFIED
          STOCK OPTIONS shall be rounded down to the nearest whole share. No
          person shall receive more than one grant of NON-QUALIFIED STOCK
          OPTIONS during any calendar year.

     (b)  The OPTION PRICE of the COMMON STOCK subject under each NON-QUALIFIED
          STOCK OPTION shall be the FAIR MARKET VALUE of the COMMON STOCK on the
          date of grant. The exercise of any NON-QUALIFIED STOCK OPTION shall be
          contingent upon receipt by the CORPORATION of (i) cash, (ii) check,
          (iii) shares of COMMON STOCK, (iv) an executed exercise notice
          together with irrevocable instructions to a broker to either sell the
          shares subject to the NON-QUALIFIED STOCK OPTION or hold such shares
          as collateral for a margin loan and to promptly deliver to the
          CORPORATION the amount of sale or loan proceeds required to pay the
          OPTION PRICE, or (v) any combination of the foregoing in an amount
          equal to the full OPTION PRICE of the shares being purchased. For
          purposes of this paragraph, shares of COMMON STOCK that are delivered
          in payment of the OPTION PRICE must have been previously owned by the
          GRANTEE for a minimum of one year, and shall be valued at their FAIR
          MARKET VALUE as of the date of the exercise of the NON-QUALIFIED STOCK
          OPTION. The CORPORATION shall not make loans to any GRANTEE for the
          purpose of exercising NON-QUALIFIED STOCK OPTIONS.

     (c)  Each NON-QUALIFIED STOCK OPTION granted under the Plan shall become
          exercisable and vested cumulatively as follows: (i) up to thirty-

                                       35
<PAGE>

          three percent (33%) of the NON-QUALIFIED STOCK OPTION may be exercised
          on or after the second anniversary of the date of grant; (ii) up to
          sixty-six percent (66%) of the NON-QUALIFIED STOCK OPTION may be
          exercised on or after the third anniversary of the date of grant; and
          (iii) up to one hundred percent (100%) of the NON-QUALIFIED STOCK
          OPTION may be exercised on or after the fourth anniversary of the date
          of grant.

     (d)  The term of each NON-QUALIFIED STOCK OPTION shall be ten years and one
          day from the date of grant, subject to earlier termination as provided
          in Section 9 hereof. Any provision of the PLAN to the contrary
          notwithstanding, no NON-QUALIFIED STOCK OPTION shall be exercised
          after the time limitations stated in this Section 5(d).

6.   Awards of Phantom Stock to Non-Employee Directors
     -------------------------------------------------

     (a)  On the first business day of each calendar year beginning on January
          1, 1998, during the duration of the PLAN, each person who is then a
          NON-EMPLOYEE DIRECTOR and who has elected to receive an award of
          PHANTOM STOCK in accordance with Section 4, shall be credited with an
          amount of PHANTOM STOCK with a value (as determined by the FAIR MARKET
          VALUE of the COMMON STOCK on the first business day of the applicable
          calendar year) equal to $5,000, $10,000, $15,000, or $20,000, as
          previously elected by the NON-EMPLOYEE DIRECTOR (the "Elected Phantom
          Stock Value"). The number of shares of PHANTOM STOCK (including
          fractions computed to three decimal places) to be granted to each NON-
          EMPLOYEE DIRECTOR each calendar year shall be determined by dividing
          the Elected Phantom Stock Value (or $10,000 in the case of a NON-
          EMPLOYEE DIRECTOR who has failed to make a timely election in
          accordance with Section 4 or who became a NON-EMPLOYEE DIRECTOR after
          June 30) by the FAIR MARKET VALUE of the COMMON STOCK on the first
          business day of the applicable calendar year. No person shall receive
          more than one grant of PHANTOM STOCK during any calendar year. The
          shares of PHANTOM STOCK awarded to a NON-EMPLOYEE DIRECTOR shall be
          credited to a newly established PHANTOM STOCK account for the NON-
          EMPLOYEE DIRECTOR. Each share of PHANTOM STOCK shall be deemed to be
          equal to one share (or fraction thereof) of COMMON STOCK on the date
          of grant, and shall thereafter fluctuate in value in accordance with
          the FAIR MARKET VALUE of the COMMON STOCK.

     (b)  Each NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account shall be credited
          quarterly on each dividend payment date with additional shares of
          PHANTOM STOCK (including fractions computed to three decimal places)
          determined by dividing (i) the aggregate amount of dividends, i.e,.
          the dividend multiplied by the number of shares of

                                       36
<PAGE>

          PHANTOM STOCK credited to the participant's account as of the dividend
          record date, by (ii) by the FAIR MARKET VALUE of the COMMON STOCK on
          the dividend payment date.

     (c)  Payment of the shares of PHANTOM STOCK credited to a NON-EMPLOYEE
          DIRECTOR'S PHANTOM STOCK account shall only be made after the NON-
          EMPLOYEE DIRECTOR'S RETIREMENT or MANDATORY RETIREMENT from the BOARD
          OF DIRECTORS. Payment shall be made only in the form of shares of
          COMMON STOCK equal to the number of shares of PHANTOM STOCK credited
          to the NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account on the date of
          distribution, rounded down to the nearest whole share. The NON-
          EMPLOYEE DIRECTOR may elect to receive the number of shares of COMMON
          STOCK to which he is entitled in a lump sum distribution of the entire
          amount or in a series of ten or less approximately equal annual
          installments, provided that distribution shall commence no later than
          January of the year following the year in which the NON-EMPLOYEE
          DIRECTOR'S RETIREMENT or MANDATORY RETIREMENT occurred.

7.   Shares of Stock Subject to the Plan
     -----------------------------------

     There shall be reserved for use under the PLAN and for the grant of any
     other INCENTIVE AWARDS pursuant to the PROGRAM (subject to the provisions
     of Section 10 hereof) a total of 34,389,230 shares of COMMON STOCK, which
     shares may be authorized but unissued shares of COMMON STOCK or issued
     shares of COMMON STOCK which shall have been reacquired by PG&E
     CORPORATION.

8.   Dividend, Voting and Other Shareholder Rights
     ---------------------------------------------

     Except as otherwise provided in the PLAN, each GRANTEE shall have all of
     the rights of a shareholder of PG&E CORPORATION with respect to all
     outstanding shares of DIRECTOR RESTRICTED STOCK registered in his or her
     name, whether or not such shares are vested, including the right to receive
     dividends and other distributions paid or made with respect to such shares
     and the right to vote such shares. No GRANTEE shall have any of the rights
     of a shareholder of PG&E CORPORATION with respect to a NON-QUALIFIED STOCK
     OPTION until the shares acquired upon exercise of such NON-QUALIFIED STOCK
     OPTION have been issued and registered in his or her name. No GRANTEE shall
     have any of the rights of a shareholder of PG&E CORPORATION with respect to

          any time, (ii) all NON-QUALIFIED STOCK OPTIONS held by the GRANTEE, to

          shares of PHANTOM STOCK by bequest or inheritance) in the form of a
          number of shares of COMMON STOCK equal to the number of shares of
          PHANTOM STOCK credited to the NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK
          account, rounded down to the nearest whole share. The term
          "disability" shall, for the purposes of the PLAN, be defined in
          Section 22(e)(3) of the CODE.

     (b)  In the event of a TERMINATION by reason of MANDATORY RETIREMENT, (i)
          all shares of DIRECTOR RESTRICTED STOCK held by the GRANTEE shall

          such shares at any time, (ii) the NON-QUALIFIED STOCK OPTIONS then
          held by the GRANTEE, to the extent that such NON-QUALIFIED STOCK
          OPTIONS have not previously expired or been exercised, shall become
          fully vested and exercisable, notwithstanding the provisions of
          Section 5(c) hereof, and the GRANTEE shall have the right to exercise
          the NON-QUALIFIED STOCK OPTIONS at any time within their respective

     (c)  In the event of a TERMINATION for any reason other than those
          specified in subparagraphs (a) and (b) above, (i) any unvested shares
          of DIRECTOR RESTRICTED STOCK granted hereunder shall be forfeited and
          the GRANTEE shall return to the CORPORATION for cancellation any stock
          certificates representing such forfeited shares which forfeited shares
          shall

                                       38
<PAGE>

          be deemed to be canceled and no longer outstanding as of the date of
          TERMINATION; and from and after the date of TERMINATION, the GRANTEE
          shall cease to be a shareholder with respect to such forfeited shares
          and shall have no dividend, voting or other rights with respect
          thereto, (ii) any NON-QUALIFIED STOCK OPTIONS granted hereunder that
          have not yet vested and become exercisable shall terminate, (iii) the

          to the extent that such NON-QUALIFIED STOCK OPTIONS have vested and
          become exercisable as of the date of TERMINATION, at any time within
          their respective terms or within three months after such TERMINATION,
          whichever is shorter, after which the NON-QUALIFIED STOCK OPTIONS
          shall terminate, and (iv) all shares of PHANTOM STOCK credited to the
          NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account shall be forfeited on
          the date of TERMINATION; provided, however, that if the TERMINATION

          STOCK credited to the NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account
          shall become payable in accordance with Section 6(c) hereof.

     (d)  Notwithstanding the provisions of subparagraphs (a) through (c) above,

          different terms and conditions pertaining to the effect of
          TERMINATION, to the extent permitted by applicable federal and state
          law.

10.  Adjustments Upon Changes in Number or Value of Shares of Common Stock
     ---------------------------------------------------------------------

     If there are any changes in the number or value of shares of COMMON STOCK
     by reason of stock dividends, stock splits, reverse stock splits,
     recapitalizations, mergers, consolidations or other events that materially
     increase or decrease the number or value of issued and outstanding shares
     of COMMON STOCK, the BOARD OF DIRECTORS or COMMITTEE may make such
     adjustments as it shall deem appropriate, in order to prevent dilution or
     enlargement of rights.

11.  Non-Transferability
     -------------------

     NON-QUALIFIED STOCK OPTIONS, PHANTOM STOCK, and shares of DIRECTOR
     RESTRICTED STOCK that have not vested in accordance with the provisions of
     Section 3(b) hereof, shall not be transferable by the GRANTEE otherwise
     than by will or the laws of descent and distribution, or pursuant to a
     qualified domestic relations order as defined by the CODE, Title I of ERISA
     or the rules thereunder.

     periods relating to the vesting of any shares of DIRECTOR RESTRICTED STOCK
     granted hereunder shall be accelerated so that all such shares immediately
     become fully vested, (ii) any time periods relating to the vesting of NON-
     QUALIFIED STOCK OPTIONS granted hereunder shall be accelerated so that all

     exercisable for the remainder of their terms, and (iii) all shares of
     PHANTOM STOCK credited to the NON-EMPLOYEE DIRECTORS' PHANTOM STOCK
     accounts shall become payable in accordance with Section 6(c) hereof as if
     the CHANGE IN CONTROL constituted a RETIREMENT.

     A "CHANGE IN CONTROL" shall be deemed to have occurred if:

     (a)  any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
          the EXCHANGE ACT, but excluding any benefit plan for EMPLOYEES or any
          trustee, agent or other fiduciary for any such plan acting in such
          person's capacity as such fiduciary), directly or indirectly, becomes
          the beneficial owner of securities of PG&E CORPORATION representing
          twenty percent (20%) or more of the combined voting power of PG&E
          CORPORATION's then outstanding securities;

     (b)  during any two consecutive years, individuals who at the beginning of
          such a period constitute the BOARD OF DIRECTORS cease for any reason
          to constitute at least a majority of the BOARD OF DIRECTORS, unless
          the election, or the nomination for election by the shareholders of
          PG&E CORPORATION, of each new DIRECTOR was approved by a vote of at
          least two-thirds (2/3) of the DIRECTORS then still in office who were
          DIRECTORS at the beginning of the period; or

     the shareholders of the CORPORATION shall have approved (i) any
     consolidation or merger of the CORPORATION other than a merger or
     consolidation which would result in the voting securities of the
     CORPORATION outstanding immediately prior thereto continuing to represent
     (either by remaining outstanding or by being converted into voting
     securities of the surviving entity or any parent of such surviving entity)
     at least 70 percent of the Combined Voting Power of the CORPORATION, such
     surviving entity or the parent of such surviving entity outstanding
     immediately after the merger or consolidation; (ii) any sale, lease,
     exchange or other transfer (in one transaction or a series of related
     transactions) of all or substantially all of the assets of the CORPORATION,
     or (iii) any plan or proposal for the liquidation or dissolution of the
     CORPORATION.  For purposes of this paragraph, the term Combined Voting
     Power shall mean the combined voting power of the CORPORATION's or other
     relevant entity's then outstanding voting securities.

13.  Amendment and Termination of the Plan
     -------------------------------------

                                       40
<PAGE>

     The BOARD OF DIRECTORS or the COMMITTEE may at any time suspend, terminate,
     modify or amend the PLAN in any respect; provided, however, that, to the
     extent necessary and desirable to comply with the CODE (or any other
     applicable law or regulation, including the requirements of any stock
     exchange on which the COMMON STOCK is listed or quoted), shareholder
     approval of any PLAN amendment shall be obtained in such a manner and to
     such a degree as is required by the applicable law or regulation.

     No suspension, termination, modification or amendment of the PLAN may,
     without the consent of the GRANTEE, adversely affect his or her rights with
     respect to DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or
     PHANTOM STOCK theretofore granted to such GRANTEE.

     Except as provided in Section 2 hereof, the BOARD OF DIRECTORS or COMMITTEE
     may make such amendments or modifications in the terms and conditions of
     any grant of DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or
     PHANTOM STOCK as it may deem advisable, or cancel or annul any grant of
     DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or PHANTOM STOCK;
     provided, however, that no such amendment, modification, cancellation or
     annulment may, without the consent of the GRANTEE, adversely affect his or
     her rights with respect to such grant.

14.  Effective Date of the Plan and Duration
     ---------------------------------------

                               PG&E CORPORATION
                       EXECUTIVE STOCK OWNERSHIP PROGRAM

                           Administrative Guidelines
                           -------------------------
                        (As amended February 16, 2000)

 1.  Description. The Executive Stock Ownership Program ("Program") was approved
     -----------
     by the Nominating and Compensation Committee of the Board of Directors on
     October 15, 1997. The Program is an important element of the Committee's
     compensation policy of aligning executive interests with those of the
     Corporation's shareholders. As an integral part of the Program, the
     Committee also authorized the use of Special Incentive Stock Ownership
     Premiums ("SISOPs") which are designed to provide incentives to Eligible
     Executives to assist in achieving minimum stock ownership targets
     established by the Committee. These Guidelines were originally adopted by
     the Committee on November 19, 1997, amended by the Committee on July 22,
     1998, October 21, 1998, and February 16, 2000. These amended Guidelines,
     along with the written materials provided to the Committee on October 15,
     1997, describe the Program which became effective on January 1, 1998. The
     Program is administered by the Corporation's Senior Human Resources
     Officer.

2.   Eligible Executives. The Chief Executive Officer shall designate the
     -------------------
     officers of the Corporation and its affiliates who shall be Eligible
     Executives covered by the Program. Initially, the officers covered by the
     Guidelines and the applicable stock ownership Target are:

- ------------------------------------------------------------------------------
</TABLE>

3.   Annual Milestones. Under the Guidelines, stock ownership levels are
     -----------------
     designed to be achieved by the end of the fifth calendar year following the
     calendar year in which an officer first becomes an Eligible Executive
     ("Target Date"). Annual Milestones have been established as a means of
     measuring progress towards achieving Targets and of providing incentives
     for Eligible Executives to expeditiously meet their Targets. The Annual
     Milestone at the end of the first full calendar year is 20 percent of the
     Target, and the Annual Milestone for each succeeding year is an additional
     20 percent of the Target. Annual Milestones shall be adjusted to reflect
     changes in base salary; provided, however, that in each instance any such
     modification shall be amortized over the remaining original five-year term.
     Following the Target Date, annual Targets also shall be modified to reflect
     changes in base salary.

4.   Calculation of Stock Ownership Levels. Stock ownership level is the dollar
     -------------------------------------
     value of stock and stock equivalents owned by an Eligible Executive and
     calculated as of the last day of the calendar year ("Measurement Date").
     The purpose of this calculation is to determine the value of the stock or
     stock equivalents owned by the Eligible Executive as compared with the
     Annual Milestone or Target for that executive. For purposes of this
     calculation, the value per share of stock or stock equivalent ("Measurement
     Value") is the average closing price of PG&E Corporation common stock as
     traded on the New York Stock Exchange for the last thirty (30) trading days
     of the year.

     a)   The value of stock beneficially owned by the Eligible Executive is
          determined by multiplying the number of shares owned beneficially on
          the Measurement Date times the Measurement Value.

     b)   The value of PG&E Corporation phantom stock units credited to the
          Eligible Executive's account in the PG&E Corporation Deferred
          Compensation Plan for Officers ("DCP") is determined by multiplying
          the number of phantom stock units credited to the Eligible Executive's
          DCP account on the Measurement Date times the Measurement Value.

     c)   The value of stock held in the PG&E Corporation stock fund of any
          defined contribution plan maintained by PG&E Corporation or any of its
          subsidiaries is the value of the Eligible Executive's PG&E Corporation
          stock fund on the Measurement Date.

     d)   The value of vested stock options is the difference between the number
          of options multiplied by the Measurement Value minus the number of
          options multiplied by the option exercise price (for purposes of this
          calculation, any value attributable to dividend equivalents is
          excluded).

5.   Award of SISOPs. SISOPs are awarded to Eligible Executives who achieve and
     ---------------
     maintain stock ownership levels prior to the end of the third year
     following the year in which an officer first became an Eligible Executive.
     For purposes of determining awards, the total stock ownership level is
     calculated as set forth under paragraph 4, on the Measurement Date. The
     amount of a SISOP award shall be equal to:

     a)   For the first year, 20 percent of the amount of the Eligible
          Executive's stock ownership level at the end of the year, up to the
          Annual Milestone, plus an additional 30 percent of the amount by which
          the stock ownership level exceeds the Annual Milestone up to the
          target; and

     b)   For each of the second and third years, 20 percent of the amount up to
          the Annual Milestone by which the end of the year stock ownership
          level exceeds the beginning of the year stock ownership level, plus an
          additional 30 percent of the amount by which the end of the year
          balance exceeds the Annual Milestone, up to the Target.

     Each time a SISOP award calculation is made, a second calculation also is
     made to determine the minimum number of shares which must be retained by
     the Eligible Executive to avoid forfeiture of the SISOP award ("Minimum
     Ownership Level") as discussed below in paragraph 8.  This calculation
     converts the dollar value of the stock ownership level used as the basis
     for qualifying for SISOPs into a number of shares of stock.  It is
     calculated by dividing the stock ownership level by the Measurement Value.

                                       2


<PAGE>

     Thus, for example, if an Eligible Executive's stock ownership level was
     $250,000 and the Measurement Value was $25 per share, then the Minimum
     Ownership Level would be 10,000 shares.

     For purposes of this calculation, the maximum share ownership level used is
     the Eligible Executive's Target.  If an Eligible Executive has a share
     ownership level higher than his/her Target, the increment over the Target
     is not included.  Thus, for example, if an Eligible Executive has a Target
     of $750,000 and his/her share ownership level is $900,000, then only
     $750,000 is used to calculate the Minimum Ownership Level.

6.   SISOPs Credited to the Deferred Compensation Plan. Upon award, SISOPs are
     -------------------------------------------------
     credited to the Eligible Executive's DCP account and converted into units
     of phantom stock each equal in value to a share of PG&E Corporation common
     stock ("SISOP units") as determined in accordance with paragraph 6 of the
     DCP. The SISOP units constitute "incentive awards" authorized to be awarded
     by the Committee to Eligible Executives under the PG&E Corporation Long-
     Term Incentive Program ("LTIP"). Upon credit of SISOP units to an Eligible
     Executive's DCP account, an equal number of shares of PG&E Corporation
     common stock shall be reserved for issuance from the pool of shares
     authorized for issuance under the LTIP. Once a SISOP unit is credited to
     the Eligible Executive's DCP account, it shall be subject to all of the
     terms and conditions specifically applicable to SISOP units under the DCP.
     Once vested in accordance with paragraph 7 below, SISOP units are
     distributed in the form of an equal number of shares of PG&E Corporation
     common stock as provided in the DCP.

7.   Vesting. SISOPs vest only upon the expiration of three years after the date
     -------
     of award (provided the Eligible Executive continues to be employed on such
     date), or, if earlier, upon an Eligible Executive's death, disability,
     Retirement, or upon a Change in Control, as defined in the LTIP. An
     Eligible Executive's unvested SISOPs will be forfeited upon termination of
     employment unless otherwise provided in the PG&E Corporation Officer
     Severance Policy.

8.   Forfeiture of SISOP Units. So long as SISOP units remain unvested, such
     -------------------------
     units are subject to forfeiture if, on each Measurement Date, the Eligible
     Executive's stock ownership is less than the Minimum Ownership Level
     established when the SISOPs were granted (see paragraph 5). To determine
     forfeiture, the following steps are followed on each Measurement Date:

     a)   The number of shares and PG&E Corporation phantom stock units credited
          to the Eligible Executive's DCP account is determined.

     b)   The share-equivalent of the value of the vested "in the money" stock
          options is determined by dividing the value of such options (computed
          in the manner described in 4(d)) by the current Measurement Value
          (e.g., if the value of the vested "in the money" options is $100,000
          and the current Measurement Value is $25 per share, then the share
          equivalent is 4,000 shares).

     c)   The number of shares, PG&E Corporation phantom stock units, and share-
          equivalents of vested "in the money" options is added together. This
          total ("Current Holdings") is compared with the Minimum Ownership
          Level determined when the SISOPs were granted. If the Current Holdings
          are equal to or greater than the Minimum Ownership Level, then no
          unvested SISOP units are forfeited. If the Current Holdings are less
          than the

                                       3

<PAGE>

          Minimum Ownership Level, then the unvested SISOP units are forfeited
          in the same proportion as the Current Holdings are less than Minimum
          Ownership Level (for example, if the Current Holdings are 20 percent
          less than the Minimum Ownership Level, then 20 percent of the SISOP
          units are forfeited).

9.   Failure to Achieve or Maintain Target. Failure to achieve stock ownership
     -------------------------------------
     levels at Target on the Target Date, or to maintain stock ownership levels
     at Target on any Measurement Date thereafter, will result in the deferral
     into the PG&E Corporation Phantom Stock Fund of the DCP of annual awards
     from the Performance Unit Plan ("PUP") and the Short Term Incentive Plan
     ("STIP"). As of any Measurement Date, to the extent that stock ownership
     levels are below Target, PUP awards shall be converted into PG&E
     Corporation Phantom Stock Units and held in the PG&E Corporation Phantom
     Stock Fund of the DCP. If, with the addition of the phantom stock units
     attributable to the PUP award, the stock ownership level is still below
     Target for any Measurement Date, any STIP award above target STIP also
     shall be converted into phantom stock units, to the extent necessary to
     achieve the Target stock ownership level. Such conversion of PUP and STIP
     awards shall continue for successive Measurement Dates, if necessary, until
     Target is met. Phantom stock units attributable to PUP and STIP awards
     described in this paragraph 9 will be paid from the DCP in a lump sum in
     January of the year following the year in which the Eligible Executive's
     employment terminates, or upon such earlier date as may have been elected
     by the Eligible Executive within thirty days after the date of mandatory
     deferral of PUP and/or STIP awards which date shall not be earlier than
     three (3) years after the date of mandatory deferral.

Note:     For the purpose of computing Pacific Gas and Electric Company's ratios
          of earning to combined fixed charges and preferred stock dividends,
          "earnings" represent net income adjusted for the minority interest in
          losses of less than 100% owned affiliates, cash distributions from and
          equity in undistributed income or loss of Pacific Gas and Electric
          Company's less than 50% owned affiliates, income taxes and fixed
          charges (excluding capitalized interest). "Fixed charges" include
          interest on long-term debt and short-term borrowings (including a
          representative portion of rental expense), amortization of bond
          premium, discount and expense, interest on capital leases, interest of

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

    PG&E Corporation is an energy-based holding company headquartered in San
Francisco, California. PG&E Corporation's Northern and Central California energy
utility subsidiary, Pacific Gas and Electric Company (the Utility), provides
natural gas and electric service to one of every 20 Americans. PG&E
Corporation's National Energy Group provides energy products and services
throughout North America.

    The National Energy Group businesses develop, construct, operate, own, and
manage independent power generation facilities that serve wholesale and
industrial customers through PG&E Generating Company, LLC (formerly U.S.
Generating Company, LLC) and its affiliates (collectively, PG&E Gen); own and
operate natural gas pipelines, natural gas storage facilities, and natural gas
processing plants, primarily in the Pacific Northwest and in Texas, through
various subsidiaries of PG&E Corporation (collectively, PG&E Gas Transmission or
PG&E GT); purchase and sell energy commodities and provide risk management
services to customers in major North American markets, including the other
National Energy Group non-utility businesses, unaffiliated utilities, marketers,
municipalities, and large end-use customers through PG&E Energy Trading--Gas
Corporation, PG&E Energy Trading--Power, L.P., and their affiliates
(collectively, PG&E Energy Trading or PG&E ET); and provide competitively priced
electricity, natural gas, and related services to industrial, commercial, and
institutional customers through PG&E Energy Services Corporation (PG&E Energy
Services or PG&E ES). In the fourth quarter of 1999, PG&E Corporation's Board of
Directors approved a plan for the divestiture of PG&E Corporation's Texas
natural gas and natural gas liquids business. Also in the fourth quarter of
1999, PG&E Corporation's Board of Directors approved a plan for the divestiture
of PG&E Corporation's retail energy services.

    This is a combined annual report of PG&E Corporation and Pacific Gas and
Electric Company. It includes separate consolidated financial statements for
each entity. The consolidated financial statements of PG&E Corporation reflect
the accounts of PG&E Corporation, the Utility, and PG&E Corporation's wholly
owned and controlled subsidiaries. The consolidated financial statements of the
Utility reflect the accounts of the Utility and its wholly owned and controlled
subsidiaries. This Management's Discussion and Analysis (MD&A) should be read in
conjunction with the consolidated financial statements included herein.

    This combined annual report, including our Letter to Shareholders and this
MD&A, contains forward-looking statements about the future that are necessarily
subject to various risks and uncertainties. These statements are based on
assumptions which management believes are reasonable and on information
currently available to management. These forward-looking statements are
identified by words such as "estimates," "expects," "anticipates," "plans,"
"believes," and other similar expressions. Actual results could differ
materially from those contemplated by the forward-looking statements.

    Factors that could cause future results to differ materially from those
expressed in or implied by the forward-looking statements or historical results
include:

    - the pace and extent of the ongoing restructuring of the electric and
      natural gas industries across the United States;

    - operational changes related to industry restructuring, including changes
      in the Utility's business processes and systems;

    - the method and timing of disposition and valuation of the Utility's
      hydroelectric generation assets;

    - the timing of the completion of the Utility's transition cost recovery and
      the consequent end of the current electric rate freeze in California;

    - any changes in the amount the Utility is allowed to collect (recover) from
      its customers for certain costs that prove to be uneconomic under the new
      competitive market (called transition costs);

    - future operating performance at the Diablo Canyon Nuclear Power Plant
      (Diablo Canyon);

    - the method adopted by the California Public Utilities Commission (CPUC)
      for sharing the net benefits of operating Diablo Canyon with ratepayers
      and the timing of the implementation of the adopted method;

    - the extent of anticipated growth of transmission and distribution services
      in the Utility's service territory;

    - future market prices for electricity;

    - future fuel prices;

                                       5
<PAGE>

    - the success of management's strategies to maximize shareholder value in
      PG&E Corporation's National Energy Group, which may include acquisitions
      or dispositions of assets, or internal restructuring;

    - the extent to which our current or planned generation development projects
      are completed and the pace and cost of such completion;

    - generating capacity expansion and retirements by others;

    - the successful integration and performance of acquired assets;

    - the outcome of the Utility's various regulatory proceedings, including the
      proposal to auction the Utility's hydroelectric generation assets, the
      electric transmission rate case applications, and post-transition period
      ratemaking proceedings;

    - fluctuations in commodity gas, natural gas liquids, and electric prices
      and our ability to successfully manage such price fluctuations; and

    - the pace and extent of competition in the California generation market and
      its impact on the Utility's costs and resulting collection of transition
      costs.

    As the ultimate impact of these and other factors is uncertain, these and
other factors may cause future earnings to differ materially from results or
outcomes we currently seek or expect. Each of these factors is discussed in
greater detail in this MD&A.

    In this MD&A, we first discuss our competitive and regulatory environment.
We then discuss earnings and changes in our results of operations for 1999,
1998, and 1997. Finally, we discuss liquidity and financial resources, various
uncertainties that could affect future earnings, and our risk management
activities. Our MD&A applies to both PG&E Corporation and the Utility.

COMPETITIVE AND REGULATORY ENVIRONMENT

    This section provides a discussion of the competitive environment in the
evolving energy industry, the California electric industry, the California
natural gas business, the National Energy Group, and regulatory matters.

THE COMPETITIVE ENVIRONMENT IN THE EVOLVING ENERGY INDUSTRY

    Historically, energy utilities operated as regulated monopolies within
specific service territories where they were essentially the sole suppliers of
natural gas and electricity services. Under this model, the energy utilities
owned and operated all of the businesses necessary to procure, generate,
transport, and distribute energy. These services were priced on a combined
(bundled) basis, with rates charged by the energy companies designed to include
all of the costs of providing these services. Now, energy utilities face
intensifying pressures to "unbundle," or price separately, those activities that
are no longer considered natural monopoly services. The most significant of
these services are electricity generation and natural gas supply.

    The driving forces behind these competitive pressures are customers who
believe they can obtain energy at lower unit prices and competitors who want
access to those customers. Regulators and legislators are responding to those
customers and competitors by providing for more competition in the energy
industry. Regulators and legislators are requiring utilities to "unbundle" rates
(separate their various energy services and the prices of those services). This
allows customers to compare unit prices of the Utility and other providers when
selecting their energy service provider.

    In the natural gas industry, Federal Energy Regulatory Commission (FERC)
Order 636 required interstate pipeline companies to divide their services into
separate gas commodity sales, transportation, and storage services. Under Order
636, interstate gas pipelines must provide transportation service regardless of
whether the customer (often a local gas distribution company) buys the gas
commodity from the pipeline.

    In the electric industry, the Public Utilities Regulatory Policies Act of
1978 (PURPA) specifically provided that unregulated companies could become
wholesale generators of electricity and that utilities were required to purchase
and use power generated by these unregulated companies in meeting their
customers' needs. The National Energy Policies Act of 1992 was designed and
implemented through FERC Orders 888 and 889 to increase competition in the
wholesale unregulated generation market by requiring access to electric utility
transmission systems by all wholesale unregulated generators, sellers, and
buyers of electricity. Now, an increasing number of states throughout the
country either have implemented plans or are considering proposals to separate
the generation from the transmission and distribution of electricity through
some form of electric industry restructuring.

                                       6
<PAGE>

    To date, the states, not the federal government, have taken the initiative
on electric industry restructuring at the retail level. While many bills
mandating restructuring of the electric industry have been introduced in
Congress, none have passed. As a result, the pace, extent, and methods for
restructuring the electric industry vary widely throughout the country. For
instance, as of December 31, 1999, 21 states had enacted electric industry
restructuring legislation, including California, Texas, Illinois, Pennsylvania,
New Jersey, Massachusetts, Rhode Island, New Hampshire, and Connecticut. There
also are some states that have passed legislation precluding or significantly
slowing down restructuring. Differences in how individual states view electric
industry restructuring often relate to the existing unit cost of energy supplies
within each state. Generally, states having higher energy unit costs are moving
more quickly to deregulate energy supply markets.

    Implementation of our national energy strategy depends, in part, upon the
opening of energy markets to provide customer choice of supplier. Undue delays
by states or federal legislation to deregulate the electric generation and
natural gas supply business could impact the pace of growth of our National
Energy Group.

THE CALIFORNIA ELECTRIC INDUSTRY

    In 1998, California became one of the first states in the country to
implement electric industry restructuring and establish a competitive market
framework for electric generation. Today, most Californians may continue to
purchase their electricity from investor-owned utilities such as Pacific Gas and
Electric Company, or they may choose to purchase electricity from alternative
generation providers (such as unregulated power generators and unregulated
retail electricity suppliers such as marketers, brokers, and aggregators). For
those customers who have not chosen an alternative generation provider,
investor-owned utilities, such as the Utility, continue to be the generation
providers. Investor-owned utilities continue to provide distribution services to
substantially all customers within their service territories, including
customers who choose an alternative generation provider.

COMPETITIVE MARKET FRAMEWORK:

    To create a competitive generation market, a Power Exchange (PX) and an
Independent System Operator (ISO) began operating on March 31, 1998. The PX
provides a competitive auction process to establish market clearing prices for
electricity in the markets operated by the PX. The ISO schedules delivery of
electricity for all market participants. The Utility continues to own and
maintain a portion of the transmission system, but the ISO controls the
operation of the system. Unless or until the CPUC determines otherwise, the
Utility is required to bid or schedule into the PX and ISO markets all of the
electricity generated by its power plants and electricity acquired under
contractual agreements with unregulated generators. Also, the Utility is
required to buy from the PX all electricity needed to provide service to retail
customers that continue to choose the Utility as their electricity supplier.

    In November 1999, the FERC approved the extension of the ISO's authority to
establish price limitations through 2000. The ISO Board increased the applicable
price limitation to $750 per megawatt-hour (MWh) on October 1, 1999, but has the
option to decrease it to $500 per MWh or make other changes, in view of the
FERC's decision. This limits the amount of volatility that occurs in the
California electricity market. However, the ISO will review the appropriate
level for any price limitations for the summer of 2000 in light of market
redesign efforts now being considered, including changes to reduce uninstructed
deviations from ISO dispatch orders and changes to permit loads to participate
by submitting bids for price-responsive demand in energy or ancillary services
markets.

    The Utility is continuing its efforts to develop and implement changes to
its business processes and systems, including the customer information and
billing system, to accommodate electric industry restructuring. To the extent
that the Utility is unable to develop and implement such changes in a successful
and timely manner, there could be an adverse impact on the Utility's or PG&E
Corporation's future results of operations.

TRANSITION PERIOD, RATE FREEZE, AND RATE REDUCTION:

    California's electric industry restructuring established a transition period
during which electric rates remain frozen at 1996 levels (with the exception
that, on January 1, 1998, rates for small commercial and residential customers
were reduced by 10 percent and remain frozen at this reduced level) and
investor-owned utilities may recover their transition costs. Transition costs
are generation-related costs that prove to be uneconomic under the new
competitive structure. The transition period ends the earlier of December 31,
2001, or when the particular utility has recovered its eligible transition
costs.

                                       7
<PAGE>

    Revenues from frozen electric rates provide for the recovery of authorized
Utility costs, including transmission and distribution service, public purpose
programs, nuclear decommissioning, and rate reduction bond debt service. To the
extent the revenues from frozen rates exceed authorized Utility costs, the
remaining revenues constitute the competitive transition charge (CTC), which
recovers the transition costs. These CTC revenues are being recovered from all
Utility distribution customers and are subject to seasonal fluctuations in the
Utility's sales volumes and certain other factors. As the CTC is collected
regardless of the customer's choice of electricity supplier (i.e., the CTC is
non-bypassable), the Utility believes that the availability of choice to its
customers will not have a material impact on its ability to recover transition
costs.

    To pay for the 10 percent rate reduction, the Utility refinanced
$2.9 billion (the expected revenue reduction from the rate decrease) of its
transition costs with the proceeds from the rate reduction bonds. The bonds
allow for the rate reduction by lowering the carrying cost on a portion of the
transition costs and by deferring recovery of a portion of these transition
costs until after the transition period. During the rate freeze, the rate
reduction bond debt service will not increase Utility customers' electric rates.
If the transition period ends before December 31, 2001, the Utility may be
obligated to return a portion of the economic benefits of the transaction to
customers. The timing of any such return and the exact amount of such portion,
if any, have not yet been determined.

TRANSITION COST RECOVERY:

    Although most transition costs must be recovered during the transition
period, certain transition costs can be recovered after the transition period.
Except for certain transition costs discussed below, at the conclusion of the
transition period, the Utility will be at risk to recover any of its remaining
generation costs through market-based revenues.

    Transition costs consist of (1) above-market sunk costs (costs associated
with utility generating facilities that are fixed and unavoidable and that were
included in customers' rates on December 20, 1995) and future sunk costs, such
as costs related to plant removal, (2) costs associated with long-term contracts
to purchase power at above-market prices from qualifying facilities (QF) and
other power suppliers, and (3) generation-related regulatory assets and
obligations. (In general, regulatory assets are expenses deferred in the current
or prior periods, to be included in rates in subsequent periods.)

    Above-market sunk costs result when the book value of a facility exceeds its
market value. Conversely, below-market sunk costs result when the market value
of a facility exceeds its book value. The total amount of generation facility
costs to be included as transition costs is based on the aggregate of
above-market and below-market values. The above-market portion of these costs is
eligible for recovery as a transition cost. The below-market portion of these
costs will reduce other unrecovered transition costs. These above- and
below-market sunk costs are related to generating facilities that are classified
as either non-nuclear or nuclear sunk costs.

    The Utility cannot determine the exact amount of above-market non-nuclear
sunk costs that will be recoverable as transition costs until the valuation of
the Utility's remaining non-nuclear generating assets, primarily its
hydroelectric generating assets, is completed. The valuation, through appraisal,
sale, or other divestiture, must be completed by December 31, 2001. The value of
seven of the Utility's other non-nuclear generating facilities was determined
when these facilities were sold to third parties. The portion of the sales
proceeds that exceeded the book value of these facilities was used to reduce
other transition costs. On September 30, 1999, the Utility filed an application
with the CPUC to determine the market value of its hydroelectric generating
facilities and related assets through an open, competitive auction. (See
"Generation Divestiture" below.) The Utility plans to use an auction process
similar to the one previously approved by the CPUC and successfully used in the
sale of the Utility's fossil and geothermal plants. If the market value of the
Utility's hydroelectric facilities is determined based upon any method other
than a sale of the facilities to a third party, a material charge to Utility
earnings could result. Any excess of market value over book value would be used
to reduce other transition costs. (See "Generation Divestiture" below.)

    For nuclear transition costs, revenues provided for transition cost recovery
are based on the accelerated recovery of the investment in Diablo Canyon over a
five-year period ending December 31, 2001. The amount of nuclear generation sunk
costs was determined separately through a CPUC proceeding and was subject to a
final verification audit that was completed in August 1998. The audit of the
Utility's Diablo Canyon accounts at December 31, 1996, resulted in the issuance
of an unqualified opinion. The audit verified that Diablo Canyon sunk costs at
December 31, 1996, were $3.3 billion of the total $7.1 billion construction
costs. The independent accounting firm also issued an agreed-upon special
procedures report, requested by the CPUC, that questioned

                                       8
<PAGE>

$200 million of the $3.3 billion sunk costs. The CPUC will review the results of
the audit and may seek to make adjustments to Diablo Canyon's sunk costs subject
to transition cost recovery. At this time, the Utility cannot predict what
actions, if any, the CPUC may take regarding the audit report.

    Costs associated with the Utility's long-term contracts to purchase electric
power are included as transition costs. Regulation required the Utility to enter
into such long-term agreements with non-utility generators. Prices fixed under
these contracts are now typically above prices for power in wholesale markets.
(See Note 14 of Notes to Consolidated Financial Statements.) Over the remaining
life of these contracts, the Utility estimates that it will purchase
299 million MWh of electric power. To the extent that the individual contract
prices are above the market price, the Utility is collecting the difference
between the contract price and the market price from customers, as a transition
cost, over the term of the contract. The contracts expire at various dates
through 2028.

    The total costs under long-term contracts are based on several variables,
including the capacity factors of the related generating facilities and future
market prices for electricity. During 1999, the average price paid under the
Utility's long-term contracts for electricity was 6.3 cents per kilowatt-hour
(kWh). The average cost of electricity purchased at market rates from the PX for
the year ended December 31, 1999, was 3.7 cents per kWh. The average cost of
electricity purchased at market rates from the PX for the period from March 31,
1998, the PX's establishment date, to December 31, 1998, was 3.2 cents per kWh.

    Generation-related regulatory assets and obligations (net generation-related
regulatory assets) are included as transition costs. At December 31, 1999 and
1998, the Utility's generation-related net regulatory assets totaled $4 billion
and $5.4 billion, respectively.

    Certain transition costs can be recovered through a non-bypassable charge to
distribution customers after the transition period. These costs include
(1) certain employee-related transition costs, (2) above-market payments under
existing long-term contracts to purchase power, discussed above, (3) up to
$95 million of transition costs to the extent that the recovery of such costs
during the transition period was displaced by the recovery of electric industry
restructuring implementation costs, and (4) transition costs financed by the
rate reduction bonds. Transition costs financed by the issuance of rate
reduction bonds will be recovered over the term of the bonds. In addition, the
Utility's nuclear decommissioning costs are being recovered through a
CPUC-authorized charge, which will extend until sufficient funds exist to
decommission the nuclear facility. During the rate freeze, the charge for these
costs will not increase Utility customers' electric rates. Excluding these
exceptions, the Utility will write off any transition costs not recovered during
the transition period.

    The Utility is amortizing its transition costs, including most
generation-related regulatory assets, over the transition period in conjunction
with the available CTC revenues. During the transition period, a reduced rate of
return on common equity of 6.77 percent applies to all generation assets,
including those generation assets reclassified to regulatory assets. Effective
January 1, 1998, the Utility started collecting these eligible transition costs
through the non-bypassable CTC and generation divestiture. For the years ended
December 31, 1999 and 1998, regulatory assets related to electric industry
restructuring decreased by $1,359 million and $609 million, respectively, which
reflects the recovery of eligible transition costs.

    During the transition period, the CPUC reviews the Utility's compliance with
accounting methods established in the CPUC's decisions governing transition cost
recovery and the amount of transition costs requested for recovery. The CPUC is
currently reviewing non-nuclear transition costs amortized during 1998 and the
first six months of 1999.

GENERATION DIVESTITURE:

    In 1998, the Utility sold three fossil-fueled generation plants for
$501 million. These three fossil-fueled plants had a combined book value at the
time of the sale of $346 million and had a combined capacity of 2,645 megawatts
(MW).

    On April 16, 1999, the Utility sold three other fossil-fueled generation
plants for $801 million. At the time of sale, these three fossil-fueled plants
had a combined book value of $256 million and had a combined capacity of 3,065
MW.

    On May 7, 1999, the Utility sold its complex of geothermal generation
facilities for $213 million. At the time of sale, these facilities had a
combined book value of $244 million and had a combined capacity of 1,224 MW.

                                       9
<PAGE>

    The gains from the sale of the fossil-fueled generation plants were used to
offset other transition costs. Likewise, the loss from the sale of the complex
of geothermal generation facilities is being recovered as a transition cost.

    The Utility has retained a liability for required environmental remediation
related to any pre-closing soil or groundwater contamination at the plants it
has sold.

    On September 30, 1999, the Utility filed an application with the CPUC to
determine the market value of its hydroelectric generating facilities and
related assets through an open, competitive auction. The Utility proposes to use
an auction process similar to the one previously approved by the CPUC and
successfully used in the sale of the Utility's fossil and geothermal plants.
Under the process proposed in the application, another subsidiary of PG&E
Corporation, PG&E Gen, would be permitted to participate in the auction on the
same basis as other bidders.

    The sale of the hydroelectric facilities would be subject to certain
conditions, including the transfer or re-issuance of various permits and
licenses by the FERC and other agencies. In addition, the FERC must approve
assignment of the Utility's Reliability Must Run Contract with the ISO for any
facility subject to such contract. Under the proposed purchase and sale
agreement, the CPUC's approval of the proposed sale on terms acceptable to the
Utility in the Utility's sole discretion is also a condition precedent to the
closing of any sale.

    On January 13, 2000, a scoping memo and ruling was issued that separates the
proceeding into two concurrent phases: one to review the potential environmental
impacts of the proposed auction under the California Environmental Quality Act
and a second to determine whether the Utility's auction proposal, or some other
alternative to the proposal, is in the public interest. The ruling notes that
the divestiture and valuation issues can best be considered after the
environmental impacts of a change in ownership have been reviewed. Potential
bidders will also be able to incorporate the costs of any mitigation measures
that may be required into their bids. The ruling sets a procedural schedule
which calls for a final decision on the Utility's auction proposal by
October 19, 2000, and a final environmental impact report published in
November 2000. The ruling also anticipates that a final CPUC decision approving
the sale would be issued by May 15, 2001. Finally, the ruling prohibits the
Utility from withdrawing its application without express CPUC authority. It is
uncertain whether the CPUC will ultimately approve the Utility's auction
proposal.

    At December 31, 1999, the book value of the Utility's net investment in
hydroelectric generation assets was approximately $0.7 billion, excluding
approximately $0.5 billion of net investment reclassified as regulatory assets.
Any excess of market value over the $0.7 billion book value would be used to
reduce transition costs, including the remaining $0.5 billion of regulatory
assets related to the hydroelectric generation assets. If the market value of
the hydroelectric generation assets is determined by any method other than a
sale of the assets to a third party, or if the winning bidder for any of the
auctioned assets is PG&E Gen, a material charge to Utility earnings could
result. The timing and nature of any such charge is dependent upon the valuation
method and procedure adopted, and the method of implementation. As discussed
below, it is possible that the CPUC will require an interim valuation through an
estimate of market value of the assets prior to transfer, sale, or other
divestiture, which could also result in a material charge. While transfer or
sale to an affiliated entity such as PG&E Gen would result in a material charge
to income, neither PG&E Corporation nor the Utility believes that the sale of
any generation facilities to a third party will have a material impact on its
results of operations.

    The Utility's ability to continue recovering its transition costs depends on
several factors, including (1) the continued application of the regulatory
framework established by the CPUC and state legislation, (2) the amount of
transition costs ultimately approved for recovery by the CPUC, (3) the
determined value of the Utility's hydroelectric generation facilities,
(4) future Utility sales levels, (5) future Utility fuel and operating costs,
and (6) the market price of electricity. Given the current evaluation of these
factors, PG&E Corporation believes that the Utility will recover its transition
costs. However, a change in one or more of these factors could affect the
probability of recovery of transition costs and result in a material charge.

POST-TRANSITION PERIOD:

    In October 1999, the CPUC issued a decision in the Utility's post-transition
period ratemaking proceeding. Among other matters, the CPUC's decision addresses
the mechanisms for ending the current electric rate freeze and for establishing
post-transition period accounting mechanisms and rates. The decision requires
Diablo Canyon generation to be priced at prevailing market rates after the
transition period. This portion of the decision is further discussed below under
"Regulatory Matters - Post-Transition Period Ratemaking Proceeding."

                                       10
<PAGE>

    The CPUC decision requires the Utility to provide quarterly forecasts of
when the Utility's rate freeze (i.e., transition period) may end based on
various assumptions regarding energy prices and the book value of the Utility's
remaining generation assets. The Utility is required to notify the CPUC three
months before the earliest forecasted end of its rate freeze and provide draft
tariff language and sample calculations of the rates that would go into effect
when the rate freeze ends. After the Utility completes its transition cost
recovery, it must implement its post-rate-freeze rates.

    The timing of the end of the rate freeze and corresponding transition period
will, in part, depend on the timing of the valuation of the Utility's
hydroelectric generating assets and the ultimate determined value of such assets
since any excess of market value over the assets' book value would be used to
reduce transition costs. If the value of the Utility's hydroelectric generation
assets is significantly higher than the related book value, the transition
period and the rate freeze could end before December 31, 2001, and potentially
could end during 2000. The CPUC is considering the Utility's proposal to auction
its hydroelectric assets, although the CPUC could also require the Utility to
implement an interim valuation of the assets. In another proceeding (the 1998
Annual Transition Cost Proceeding (ATCP)), a CPUC administrative law judge
issued a proposed decision on January 7, 2000, which contained a proposed change
to the rules previously in place for the amortization of transition costs. Under
the final decision, issued on February 17, 2000, on a prospective basis the
utilities are required to assess the estimated market value of their remaining
non-nuclear generating assets, including the land associated with those assets,
on an aggregate basis at a value not less than the net book value of those
assets and to credit the Transition Cost Balancing Account (TCBA) with the
estimated value. The decision encourages the utilities to base such estimates on
realistic assessments of the market value of the assets. The final decision did
not adopt the proposed decision's recommendation to establish a new regulatory
asset account that would allow a true-up when the estimated market value is
greater than actual market value. However, the decision states that crediting
the TCBA with the aggregate net book value of the remaining non-nuclear
generating assets is a conservative approach and remedies any concerns regarding
the lack of a true-up. The decision provides that if the estimated market
valuation is less than book value for any individual asset, accelerated
amortization of the associated transition costs will continue until final market
valuation of the asset occurs through sale, appraisal, or other divestiture. If
the final value of the assets, determined through sale, appraisal, or other
divestiture, is higher than the estimate, the excess amount would be used to pay
remaining transition costs, if any. The utilities are required to file the
adjusted entries to their respective TCBA based on the estimated market values
with the CPUC by March 9, 2000. The filing will become effective after
appropriate review by the CPUC's Energy Division and the TCBA entries are
subject to review in the next ATCP. If an estimate of the market value of the
non-nuclear generating assets is adopted that exceeds the aggregate net book
value of those assets, a charge to earnings would result.

    After the rate freeze and transition periods end, the Utility must refund to
electric customers any over-collected transition costs (plus interest at the
Utility's authorized rate of return) within one year after the end of the rate
freeze. The Utility also will be prohibited from collecting after the rate
freeze any electric costs incurred during the rate freeze but not recovered
during the rate freeze, including costs that are not classified as transition
costs. Through the end of its rate freeze, the Utility will continue to incur
certain non-transition costs and place those costs into balancing and memorandum
accounts for future recovery. There is a risk that the Utility will be unable to
collect certain non-transition costs that, due to lags in the regulatory cost
approval process, have not been approved for recovery nor collected when the
rate freeze ends. The Utility is unable to predict the amount of such potential
unrecoverable costs.

    The CPUC also has established the Purchased Electric Commodity Account for
the Utility to track energy costs after the rate freeze and transition period
end. The CPUC intends to explore other ratemaking issues, including whether
dollar-for-dollar recovery of energy costs is appropriate, in the second phase
of the post-transition electric ratemaking proceeding. There are three primary
options for the future regulatory framework for utility electric energy
procurement cost recovery after the rate freeze: (1) a CPUC-defined procurement
practice, that if followed by the Utility, would pass through costs without the
need for reasonableness reviews, (2) a pass-through of costs subject to
after-the-fact reasonableness reviews, or (3) a procurement incentive mechanism
with rewards and penalties determined based on the Utility's energy purchasing
performance compared to a benchmark. The Utility proposed adoption of either a
defined procurement practice or a procurement incentive mechanism, neither of
which would involve reasonableness reviews. The volatility of earnings and risk
exposure of the Utility related to post-transition period purchases of
electricity is dependent on which of these options, or some other approach, is
adopted.

                                       11
<PAGE>

    After the transition period, the Utility's future earnings from its electric
distribution will be subject to volatility as a result of sales fluctuations.

DISTRIBUTED GENERATION AND ELECTRIC DISTRIBUTION COMPETITION:

    In October 1999, the CPUC issued a decision outlining how the CPUC, in
cooperation with other regulatory agencies and the California Legislature, plans
to address the issues surrounding distributed generation, electric distribution
competition, and the role of the utility distribution companies (such as Pacific
Gas and Electric Company) in the competitive retail electric market. Distributed
generation enables siting of electric generation technologies in close proximity
to the electric demand (referred to as "load"). The CPUC decision opened a new
rulemaking proceeding to examine various issues concerning distributed
generation, including interconnection issues, who can own and operate
distributed generation, environmental impacts, the role of utility distribution
companies, and the rate design and cost allocation issues associated with the
deployment of distributed generation facilities. With respect to electric
distribution competition, the CPUC directed its staff to deliver a report by
April 21, 2000, on the different policy options that the CPUC, in cooperation
with the California Legislature, can pursue. Following the issuance of the
report, the CPUC expects to open one or more new proceedings to address electric
distribution competition and competition in the retail electric market.

THE CALIFORNIA NATURAL GAS BUSINESS

    Restructuring of the natural gas industry on both the national and the state
levels has given choices to California utility customers to meet their gas
supply needs. The Utility offers transmission, distribution, and storage
services as separate and distinct services to its industrial and larger
commercial gas (noncore) customers. Customers have the opportunity to select
from a menu of services offered by the Utility and they pay only for the
services that they use. Access to the transmission system is possible for all
gas marketers and shippers, as well as noncore end users.

    The Utility's residential and smaller commercial gas (core) customers can
select the commodity gas supplier of their choice. However, the Utility
continues to purchase gas as a regulated supplier for those core customers who
request it, serving 3.8 million core customers in its service territory.

    The Utility's costs of purchasing gas for core customers through 2002 are
regulated by the core procurement incentive mechanism, a form of incentive
ratemaking that provides the Utility a direct financial incentive to procure gas
and transportation services at the lowest reasonable costs by comparing all
procurement costs to an aggregate market-based benchmark. If costs fall within a
range (referred to as "tolerance band") around the benchmark, costs are
considered reasonable and fully recoverable from ratepayers. If procurement
costs fall outside the tolerance band, ratepayers and shareholders share savings
or costs, respectively.

    The Gas Accord settlement agreement, approved by the CPUC in 1997,
established gas transmission rates within California for the period from
March 1998 through December 2002 for the Utility's core and noncore customers
and eliminated regulatory protection against variations in noncore transmission
revenues. As a result, the Utility is at risk for variations between actual and
forecasted transmission throughput volumes.

    Rates for gas distribution services continue to be set by the CPUC and are
designed to provide the Utility an opportunity to recover its costs of service
and include a return on its investment. The regulatory mechanisms for setting
gas distribution rates are discussed below under "Regulatory Matters."

NATIONAL ENERGY GROUP

    PG&E Corporation's National Energy Group has been formed to pursue
opportunities created by the gradual restructuring of the energy industry across
the nation. The National Energy Group integrates our national power generation,
gas transmission, and energy trading and services businesses. The National
Energy Group contemplates increasing PG&E Corporation's national market presence
through a balanced program of acquisition and development of energy assets and
businesses, while at the same time undertaking ongoing portfolio management of
its assets and businesses. PG&E Corporation's ability to anticipate and capture
profitable business opportunities created by restructuring will have a
significant impact on PG&E Corporation's future operating results.

    Certain New England states where our National Energy Group operates electric
generation facilities were, like California, among the first states in the
country to introduce electric industry restructuring. As a result of this
restructuring and certain other regulatory initiatives, the wholesale
unregulated electricity market in New England features a bid-based market and an
ISO.

                                       12

INDEPENDENT POWER GENERATION:

    Through PG&E Gen and its affiliates, we participate in the development,
construction, operation, ownership, and management of non-utility electric
generating facilities that compete in the United States power generation market.
In September 1998, PG&E Corporation, through its indirect subsidiary USGen New
England, Inc. (USGenNE), completed the acquisition of a portfolio of electric
generation assets and power supply contracts from the New England Electric
System (NEES). The purchased assets include hydroelectric, coal, oil, and
natural gas generation facilities with a combined generating capacity of about
4,000 MW.

    Including fuel and other inventories and transaction costs, the financing
requirements for this transaction were approximately $1.8 billion, funded
through an aggregate of $1.3 billion of PG&E Gen and USGenNE debt and a
$425 million equity contribution from PG&E Corporation. The net purchase price
has been allocated as follows: (1) electric generating assets of $2.3 billion,
(2) receivable for support payments of $0.8 billion, and (3) above-market
contractual obligations of $1.3 billion, relating to acquired power purchase
agreements, gas agreements, and standard offer agreements.

    As part of the New England electric industry restructuring, the local
utility companies were required to offer Standard Offer Service (SOS) to their
retail customers. Retail customers may select alternative suppliers at any time.
The SOS is intended to provide customers with a price benefit (the commodity
electric price offered to the retail customer is expected to be less than the
market price) for the first several years, followed by a price disincentive that
is intended to stimulate the retail market.

    Retail customers may continue to receive SOS through June 30, 2002, in New
Hampshire (subject to early termination on December 31, 2000, at the discretion
of the New Hampshire Public Service Commission), through December 31, 2004, in
Massachusetts, and through December 31, 2009, in Rhode Island. However, if
customers choose an alternate supplier, they are precluded from going back to
the SOS.

    In connection with the purchase of the generation assets, USGenNE entered
into wholesale agreements with certain of the retail companies of NEES to supply
at specified prices the electric capacity and energy requirements necessary for
their retail companies to meet their SOS obligations. These companies are
responsible for passing on to us the revenues generated from the SOS. USGenNE
currently is indirectly serving a large portion of the SOS electric capacity and
energy requirements for these companies, except in New Hampshire. For the year
ended December 31, 1999, the SOS price paid to generators was $0.035 per Kwh for
generation. On March 1, 1999, Constellation Power Source, Inc. (Constellation)
won the New Hampshire component of the SOS through a competitive bidding
solicitation. On January 7, 2000, USGenNE paid approximately $15 million to a
third party for this third party's assumption of 10 percent of the Massachusetts
Electric Company/Nantucket Electric Company SOS and 40 percent of the
Narragansett SOS.

    Like other utilities, New England utilities previously entered into
agreements with unregulated companies (e.g., qualifying facilities under PURPA)
to provide energy and capacity at prices that are anticipated to be in excess of
market prices. We assumed NEES' contractual rights and duties under several of
these power purchase agreements. At December 31, 1999, these agreements provided
for an aggregate 470 MW of capacity. However, NEES will make support payments to
us toward the cost of these agreements. The support payments by NEES total
$0.9 billion in the aggregate (undiscounted) and are due in monthly installments
from September 1998 through January 2008. In certain circumstances, with our
consent, NEES may make a full or partial lump-sum accelerated payment.

    Initially, approximately 90 percent of the acquired operating capacity,
including capacity and energy generated by other companies and provided to us
under power purchase agreements, is dedicated to servicing SOS customers. To the
extent that customers eligible to receive SOS choose alternate suppliers, or as
these obligations are sold to other parties, this percentage will decrease. As
customers choose alternate suppliers, or the SOS obligations are sold, a greater
proportion of the output of the acquired operating capacity will be subject to
market prices.

GAS TRANSMISSION OPERATIONS:

    PG&E Corporation participates in the "midstream" portion of the gas business
through PG&E GT NW. PG&E GT NW owns and operates gas transmission pipelines and
associated facilities which extend over 612 miles from the Canada-U.S. border to
the Oregon-California border. PG&E GT NW provides firm and interruptible
transportation services to third party shippers on an open-access basis. Its
customers are principally retail gas

                                       13
<PAGE>

distribution utilities, electric utilities that use natural gas to generate
electricity, natural gas marketing companies, natural gas producers, and
industrial consumers.

    On January 27, 2000, PG&E Corporation's National Energy Group signed a
definitive agreement with El Paso Field Services Company (El Paso) providing for
the sale to El Paso, a subsidiary of El Paso Energy Corporation, of the stock of
PG&E Gas Transmission, Texas Corporation and PG&E Gas Transmission Teco, Inc.
(collectively, PG&E GTT). The consideration to be received by the National
Energy Group includes $279 million in cash subject to a working capital
adjustment, the assumption by El Paso of debt having a book value of
$624 million, and other liabilities associated with PG&E GTT.

    In 1999, PG&E Corporation recognized a charge against earnings of $890
million after tax, or $2.42 per share, to reflect PG&E GTT's assets at their
fair market value. The composition of the pre-tax charge is as follows: (1) an
$819 million write-down of net property, plant, and equipment, (2) the
elimination of the unamortized portion of goodwill, in the amount of $446
million, and (3) an accrual of $10 million representing selling costs.

    Proceeds from the sale will be used to retire short-term debt associated
with PG&E GTT's operations and for other corporate purposes. Closing of the
sale, which is expected in the first half of 2000, is subject to approval under
the Hart Scott Rodino Act.

ENERGY TRADING:

    Through PG&E ET, we purchase bulk volumes of power and natural gas from PG&E
Corporation affiliates and the wholesale market. We then schedule, transport,
and resell these commodities, either directly to third parties or to other PG&E
Corporation affiliates. PG&E ET also provides risk management services to PG&E
Corporation's other businesses (except the Utility) and to wholesale customers.
(See "Price Risk Management Activities" below; and Note 3 of the Notes to
Consolidated Financial Statements.)

ENERGY SERVICES:

    In December 1999, PG&E Corporation's Board of Directors approved a plan to
dispose of PG&E ES, its wholly owned subsidiary, through a sale. As of December
31, 1999, the intended disposal has been accounted for as a discontinued
operation. In connection with this transaction, PG&E Corporation's investment in
PG&E ES was written down to its estimated net realizable value. In addition,
PG&E Corporation provided a reserve for anticipated losses through the date of
sale. The total provision for discontinued operations was $58 million, net of
income taxes of $36 million. While there is no definite sales agreement, it is
expected that the disposition will be completed in 2000. The amounts that PG&E
Corporation will ultimately realize from this disposal could be materially
different from the amounts assumed in arriving at the estimated loss on disposal
of the discontinued operations. The PG&E ES business segment generated net
losses of $40 million (or $0.11 per share), $52 million (or $0.14 per share),
and $29 million (or $0.07 per share), for the years ended December 31, 1999,
1998, and 1997, respectively.

REGULATORY MATTERS

    A significant portion of PG&E Corporation's operations are regulated by
federal and state regulatory commissions. These commissions oversee service
levels and, in certain cases, PG&E Corporation's pricing for its regulated
services. Following are the percentages of 1999 revenues that fell under the
jurisdiction of these various regulatory agencies:

<TABLE>
<CAPTION>
                                                              UTILITY    CONSOLIDATED
<S>                                                           <C>        <C>

</TABLE>

    The Utility is the only subsidiary with significant regulatory proceedings
at this time. Some of the items that affected reported 1999 results, and will
affect future Utility authorized revenues, include the 1999 General Rate Case,
the year 2000 cost of capital proceeding, the post-transition period ratemaking
proceeding, the FERC transmission rate cases, the catastrophic event memorandum
account proceeding, the CPUC's gas strategy investigation-Phase 2, and the 1997
and 1998 electric base revenue increase proceeding. These items are discussed
below. Any requested change in authorized electric revenues resulting from any
of the electric proceedings would not impact the Utility's customer electric
rates through the transition period because these rates are frozen in accordance
with the electric transition plan. However, the amount of remaining revenues
providing for the

                                       14
<PAGE>

recovery of transition costs would be affected. Any change in authorized gas
revenues resulting from gas proceedings would increase or decrease the Utility's
customer gas rates.

THE 1999 GENERAL RATE CASE (GRC):

    In December 1997, the Utility filed its 1999 GRC application with the CPUC.
During the GRC process, the CPUC examines the Utility's costs to determine the
amount the Utility may charge customers for base revenues (non-fuel related
costs). The Utility requested distribution revenue increases to maintain and
improve natural gas and electric distribution reliability, safety, and customer
service. The requested revenues, as updated, included an increase of
$445 million in electric base revenues and an increase of $377 million in
natural gas base revenues over the 1998 authorized revenues.

    The Utility received a final decision on its 1999 GRC application on
February 17, 2000. This final decision increased electric distribution revenues
by $163 million and gas distribution revenues by $93 million, as compared to
revenues authorized for 1998. This revenue increase is retroactive to
January 1, 1999. The impact of these increases resulted in an increase in
earnings of $153 million, or $0.42 per share, and was reflected in the fourth
quarter of 1999.

    The Utility's GRC application also contained a proposal for an Attrition
Rate Adjustment (ARA) to adjust revenues in 2000 and 2001 if a performance-based
ratemaking (PBR) mechanism is not adopted for 2000 or 2001. The final decision
denies the Utility's request for an ARA to adjust revenues in 2000, but adopts
an ARA for 2001. The final decision orders that the CPUC oversee an audit of the
Utility's 1999 distribution capital spending, and that the 2001 ARA be subject
to modification to take into account the results of the audit. The 2001 ARA will
also be subject to modification to recognize amounts recorded in a new balancing
account that the final decision requires be established for vegetation
management expenses.

THE YEAR 2000 COST OF CAPITAL PROCEEDING:

    In November 1999, the Utility filed its 2000 cost of capital application
with the CPUC to establish its authorized rates of return on an unbundled basis
for electric and natural gas distribution operations. To reflect increasing
interest rates, the Utility has requested a return on equity (ROE) of
12.5 percent and an overall rate of return of 9.76 percent as compared to its
1999 authorized rates of 10.6 percent ROE and 8.75 percent overall rate of
return. The Utility has not requested any change in its authorized capital
structure for 2000. The Utility's current authorized capital structure is
46.2 percent long-term debt, 5.8 percent preferred stock, and 48 percent common
equity.

    If granted, the requested ROE would increase electric distribution revenues
by approximately $127.8 million and natural gas distribution revenues by
approximately $36.6 million, based on the rate base authorized in the Utility's
1999 GRC. The Utility requested that a final CPUC decision be issued in
June 2000. On February 17, 2000, the CPUC issued a decision to allow the final
CPUC decision, when it is adopted, to be effective retroactively to
February 17, 2000.

    Consistent with the rate freeze, there will be no change in electric rates
in 2000. Also, the return on the Utility's electric transmission-related assets
will be determined by the FERC in 2000. Finally, the return on the Utility's
natural gas transmission and storage business was incorporated in rates
established in the Gas Accord.

POST-TRANSITION PERIOD RATEMAKING PROCEEDING:

    In October 1999, the CPUC issued a decision in the Utility's post-transition
period ratemaking proceeding. Among other matters, the CPUC's decision addresses
the mechanisms for ending the current electric rate freeze and for establishing
post-transition period accounting mechanisms and rates.

    The decision prohibits the Utility from continuing to price electric
generation from Diablo Canyon based on the incremental cost incentive price
(ICIP) after the transition period has ended. The ICIP, which has been in place
since January 1, 1997, is a performance-based mechanism that establishes a rate
per kWh generated by the facility. The ICIP prices for 1999, 2000, and 2001 are
3.37 cents per kWh, 3.43 cents per kWh, and 3.49 cents per kWh, respectively.
The average price for base load electric energy (the price received for a
constant level of electric generation for all hours of electric demand) sold at
market rates to the California PX for the 12-month period ended December 31,
1999, was 3.7 cents per kWh. The average price for base load electric energy
sold at market rates to the PX from March 31, 1998, the PX's establishment date,
to December 31, 1998, was 3.2 cents per kWh.

                                       15
<PAGE>

Future market prices may be higher or lower. Under the CPUC's decision, after
the transition period, the Utility must price Diablo Canyon generation at the
prevailing market price for power.

    Further, pursuant to the 1997 CPUC decision establishing the ICIP, the
Utility is required to begin sharing 50 percent of the net benefits of operating
Diablo Canyon with ratepayers commencing January 1, 2002. The CPUC may interpret
a more recent decision to commence the benefit-sharing at the end of the
transition period. The Utility is required to file an application by July 2000
with its proposal for the methods to be used in the valuation of the benefits
associated with the operation of Diablo Canyon, and the mechanism to be used to
share these benefits with ratepayers. The Utility and PG&E Corporation are
unable to predict what type of valuation and sharing mechanism will be adopted
and what the ultimate financial impact of the sharing mechanism will have on
results of operation or financial position.

    The CPUC's decision also prohibits the Utility from collecting after the
rate freeze any electric costs incurred but not recovered during the rate
freeze, including costs that are not transition costs and are not related to
generation assets such as under-collected accounting balances relating to power
purchases.

    See the discussion above under "Competitive and Regulatory Environment --
The California Electric Industry Post-Transition Period."

    In November 1999, the Utility filed an application for rehearing the CPUC's
decision.

    The ultimate financial impact of the provisions of the CPUC's decision
described above will depend on the date the Utility's transition cost recovery
is completed and the rate freeze ends, future costs including Diablo Canyon
operating costs, future market prices for electricity, the amount of any
electric non-transition costs that have been incurred but not recovered as of
the end of the rate freeze, the timing of various regulatory proceedings in
which the Utility seeks approval for rate recovery of various costs incurred
during the rate freeze, and other variables that PG&E Corporation and the
Utility are unable to predict.

FERC TRANSMISSION RATE CASES:

    Since April 1998, all electric transmission revenues are authorized by the
FERC. During 1998 and 1999, the FERC issued orders that put into effect various
rates to recover electric transmission costs from the Utility's former bundled
rate transmission customers. All 1998 and 1999 rates currently are subject to
refund, pending final decisions in the transmission cases. In April 1999, the
Utility filed a settlement with the FERC that, if approved, would allow the
Utility to recover $345 million for the period of April 1998 through May 1999.
In May 1999, the FERC accepted, subject to refund, the Utility's March 1999
request to begin recovering, as of May 31, 1999, $324 million annually. In
October 1999, the FERC accepted, subject to refund, the Utility's request to
increase revenues to $370 million annually, beginning in April 2000. The Utility
does not expect a material impact on its financial position or results of
operations resulting from these matters.

CATASTROPHIC EVENT MEMORANDUM ACCOUNT PROCEEDING:

    In September 1999, the Utility entered into a Settlement Agreement with the
CPUC's Office of Ratepayer Advocates (ORA), and other parties, in a proceeding
addressing the Catastrophic Events Memorandum Account. The settlement provides
for a $59 million increase in electric distribution revenue requirement and an
$11 million increase in gas distribution revenue requirement effective
January 1, 2000. The increase compensates the Utility for service restoration
following several events, beginning with the Oakland Hills fire of 1991 and
ending with the storms of February 1998. A CPUC decision is expected in early
2000.

THE CPUC'S GAS STRATEGY INVESTIGATION, PHASE 2:

    In January 1998, the CPUC opened a rulemaking proceeding to explore changes
in the natural gas industry in California. In July 1999, the CPUC issued a
decision identifying promising options for restructuring the natural gas
industry. In the decision, the CPUC reaffirmed the basic structure of the Gas
Accord. The CPUC further stated that it seeks to explore a market structure that
maintains the utilities' traditional role of providing fully integrated default
service while removing obstacles to competitive unbundled services. The CPUC
opened a new investigative proceeding to explore in more detail the anticipated
costs and benefits associated with the different market structure options it has
identified. On January 28, 2000, PG&E Corporation and a broad-based coalition of
shippers, consumer groups, marketers, and others filed a settlement with the
CPUC which would reaffirm the basic structure of the Gas Accord and continue the
Gas Accord through its original term of December 31, 2002.

                                       16
<PAGE>

ELECTRIC BASE REVENUE INCREASE PROCEEDING:

    Section 368(e) of the California Public Utilities Code was adopted as part
of the California electric industry restructuring legislation. It provided for
an increase in the Utility's electric base revenues for 1997 and 1998, for
enhancement of transmission and distribution system safety and reliability. In
accordance with Section 368(e), the CPUC authorized a 1997 base revenue increase
of $164 million. For 1998, the CPUC authorized an additional base revenue
increase of $77 million. Section 368(e) expenditures are subject to review by
the CPUC.

    In July 1999, the ORA filed reports on the Utility's Section 368(e)
expenditures recommending a disallowance of $88.4 million in expenditures for
1997 and 1998. In August 1999, The Utility Reform Network (TURN) recommended an
additional $14 million disallowance for a total recommended disallowance for
1997 and 1998 expenditures of $102.4 million. The Utility opposed the
recommended disallowances and hearings were held in October 1999. A proposed
decision is not expected until the first quarter of 2000. Any proposed decision
would be subject to comment by the parties and change by the CPUC before a final
decision is issued. The Utility does not expect a material impact on its
financial position or results of operations resulting from these matters.

RESULTS OF OPERATIONS

    In this section, we present the components of our results of operations for
1999, 1998, and 1997. The Utility received a final decision on its 1999 GRC
application on February 17, 2000. As discussed further in "Regulatory Matters"
above, the final decision did not increase electric revenues, although it
increased the deferral of electric transition costs by $163 million over the
amount that would have been deferred under the 1998 revenue requirement. This
revenue increase was retroactive to January 1, 1999. The impact of the 1999 GRC
resulted in an increase in earnings of $153 million, or $0.42 per share, and was
reflected in the fourth quarter of 1999.

    The table below shows for 1999, 1998, and 1997, certain items from our
Statement of Consolidated Income detailed by Utility and National Energy Group
operations of PG&E Corporation. (In the "Total" column, the table shows the
combined results of operations for these groups.) The information for PG&E
Corporation (the "Total" column) excludes transactions between its subsidiaries
(such as the purchase of natural gas by the Utility from the unregulated
business operations). Following this table we discuss earnings and explain why
the components of our results of operations varied from the year before for 1999
and 1998.

OVERALL RESULTS

    PG&E Corporation had a net loss in 1999 of $73 million, or $0.20 per share.
In 1998 PG&E Corporation had net income of $719 million, or $1.88 per share. The
decrease is principally due to the write-down to fair value of our natural gas
business in Texas and the accrual for the discontinuance of operations of our
Energy Services segment. The PG&E GTT write-down was approximately $890 million
after taxes, and the PG&E ES discontinued operations generated a charge of
$58 million after tax. Partially offsetting these charges were increases in
Utility income, primarily as a result of the 1999 GRC, and an adjustment of a
litigation reserve associated with a court-approved settlement proposal. In
addition, PG&E Gen changed its method of accounting for major maintenance and
overhauls at its generating facilities. Effective January 1, 1999, PG&E Gen
adopted a method that accounts for expenditures associated with major
maintenance and overhauls as incurred. Previously, PG&E Gen estimated the cost
of major maintenance and overhauls and accrued such costs in advance in a
systematic and rational manner over the period between major maintenance and
overhauls. The cumulative effect of the accounting change resulted in
recognition of approximately $12 million of income, net of tax.

    The Utility's net income available for common stock increased to $763
million in 1999 as compared to 1998 net income of $702 million, primarily
because of the impacts of the 1999 GRC. However, the increases from the

                                       18
<PAGE>

GRC were partially offset by a reduction in the Utility's authorized cost of
capital and a lower return on its assets due to the sale of a significant
portion of its generating assets and recovery of transition costs (see Note 2 of
the Notes to Consolidated Financial Statements).

    Net income for the Utility decreased $33 million in 1998 as compared to 1997
due to the reduced rate of return on generation assets and increased interest
expense associated with the rate reduction bonds.

OPERATING INCOME

    Operating income for PG&E Corporation in 1999 was $878 million, which
includes the charge to write down the investment in PG&E GTT to its net
realizable value. Operating income for the Utility was $1,993 million in 1999 as
compared to $1,876 million in 1998. This increase is primarily because of the
impacts of the 1999 GRC. However, the increases from the GRC were partially
offset by a reduction in the Utility's authorized cost of capital and a lower
return on its assets due to the sale of a significant portion of its generating
assets and recovery of transition costs (see Note 2 of the Notes to Consolidated
Financial Statements).

    Operating income of the National Energy Group decreased $62 million in 1999
as compared to 1998, excluding the charge to write PG&E GTT down to its net
realizable value. The decline resulted from mild weather in the Northeast, lower
interruptible sales in the Pacific Northwest, less portfolio management
activity, and trading losses in the U.S. gas portfolio. This decline was
partially offset by cost containment efforts across the organization and an
increase in the differential between natural gas liquids prices and the cost of
natural gas.

    The operating income increase in 1998 as compared to 1997 was primarily due
to the growth of the National Energy Group, which contributed $195 million of
the increase. The 1998 income from continuing operations also includes a loss on
the sale of our Australian energy holdings.

OPERATING REVENUES

UTILITY:

    Utility operating revenues increased $304 million in 1999 as compared to
1998. This increase is primarily due to: (1) a $147 million increase in gas
revenues from residential and commercial gas customers due to higher usage, (2)
a $93 million increase in gas revenues as a result of the GRC, (3) a $43 million
increase in revenues from small and medium electric customers due to increased
customers, and (4) a $16 million increase in revenues from an increase in gas
transportation volumes.

    Utility operating revenues decreased $571 million in 1998 as compared to
1997. This decrease is primarily due to: (1) a $410 million decrease for the 10
percent electric rate reduction provided to residential and small commercial
customers, which was partially offset by $108 million of higher revenues due to
increased consumption of electricity by these customers, (2) a $151 million
decrease in revenues from medium and large electric customers, many of whom are
now purchasing their electricity directly from unregulated power generators,
(3) a $63 million decrease in sales to commercial and agricultural electric
customers resulting from their lower demand for irrigation water pumping as a
result of heavier rainfall in 1998, and (4) a $100 million decrease for the
termination of the volumetric (ERAM) and energy cost (ECAC) revenue balancing
accounts. The ERAM and ECAC accounts were replaced with the TCBA, which affects
expenses, rather than revenues.

NATIONAL ENERGY GROUP:

    The National Energy Group's 1999 operating revenues increased $939 million
as compared to 1998 operating revenues, principally due to: (1) the PG&E Gen
business segment receiving a full year of revenue from the New England assets
acquired in September 1998, and (2) increases in trading revenues at PG&E ET
reflecting the further maturation of its business. The 1999 operating revenues
also reflect revenue increases resulting from an improved differential between
the natural gas liquids prices and the incoming natural gas. These revenue
increases were partially offset by (1) a decline in interruptible revenues in
the Northwest due to the lower natural gas prices in the Southwest as compared
to Canadian prices, and (2) lower transportation revenue on the Texas
transmission system. In addition, effective July 1999, certain gas trading
activities conducted by PG&E GTT were transferred to PG&E ET, thus contributing
to the decline in PG&E GTT revenues.

    Operating revenues associated with the National Energy Group increased
$4,893 million in 1998 as compared to 1997. This was primarily due to revenue
increases from energy trading volumes, 12 months of revenue from the

                                       19
<PAGE>

Texas acquisitions versus seven months in 1997, portfolio management activity by
PG&E Gen, and the acquisition of the New England generating assets in
September 1998.

OPERATING EXPENSES

UTILITY:

    The Utility's operating expenses increased $187 million in 1999 as compared
to 1998. This increase reflects the increased cost of gas due to higher usage
and the increased amortization of electric transition costs.

    Utility operating expenses in 1998 decreased $627 million as compared to
1997. This decrease reflects a reduction in the amount of amortization of
transition costs, primarily due to lower revenues from residential and small
commercial customers discussed above in "Operating Revenues--Utility". Also
contributing to the decrease in operating expenses was a reduction in gas
transportation demand charges of $134 million, due to the expiration of
contracted pipeline capacity.

NATIONAL ENERGY GROUP:

    The National Energy Group's operating expenses increased $2,276 million in
1999 as compared to 1998, due to the charge associated with the disposition of
PG&E GTT, having a full year of operating expenses associated with the
generation facilities in New England, and growth of PG&E ET operations.

    Operating expenses for the National Energy Group increased $4,613 million in
1998 as compared to 1997. This increase reflects the increase in the volumes of
energy commodities purchased, operating costs associated with the New England
assets acquired in September 1998 and the gas transportation assets acquired in
1997.

INCOME TAXES

    PG&E Corporation has recorded income tax expense of $248 million for 1999.
The effective tax rate primarily results from two factors: (1) electric industry
restructuring has resulted in the reversal of temporary differences whose tax
benefits were originally flowed through to customers causing an increase in
income tax expense independent of pre-tax income, and (2) the disposition of
PG&E GTT resulted in a capital loss for tax purposes, which could not be fully
recognized.

    Income taxes in 1998 increased $46 million as compared to 1997. The overall
effective tax rate increased 1.1 percent in 1998 largely due to accelerated book
depreciation and amortization related to electric industry restructuring. These
increases were partially offset by a lowered effective state tax rate resulting
from our expanded business operations.

DIVIDENDS

    We base our common stock dividend on a number of financial considerations,
including sustainability, financial flexibility, and competitiveness with
investment opportunities of similar risk. Our current quarterly common stock
dividend is $.30 per common share, which corresponds to an annualized dividend
of $1.20 per common share. We continually review the level of our common stock
dividend, taking into consideration the impact of the changing regulatory
environment throughout the nation, the resolution of asset dispositions, the
operating performance of our business units, and our capital and financial
resources in general.

    The CPUC requires the Utility to maintain its CPUC-authorized capital
structure, potentially limiting the amount of dividends the Utility may pay PG&E
Corporation. During 1999, the Utility has been in compliance with its
CPUC-authorized capital structure. PG&E Corporation and the Utility believe that
this requirement will not affect PG&E Corporation's ability to pay common stock
dividends. However, depending on the timing and outcome of the valuation of the
Utility's hydroelectric facilities discussed in "Generation Divestiture" above,
certain valuation methods could necessitate a waiver of the CPUC's authorized
capital structure in order to permit PG&E Corporation or the Utility to continue
paying common stock dividends at the current level.

LIQUIDITY AND FINANCIAL RESOURCES

CASH FLOWS FROM OPERATING ACTIVITIES

    Net cash provided by PG&E Corporation's operating activities totaled
$2,287 million, $2,283 million, and $2,618 million in 1999, 1998, and 1997,
respectively. Net cash provided by the Utility's operating activities totaled
$2,200 million, $2,610 million, and $1,768 million in 1999, 1998, and 1997,
respectively.

CASH FLOWS FROM FINANCING ACTIVITIES

PG&E CORPORATION:

    We fund investing activities from cash provided by operations after capital
requirements and, to the extent necessary, external financing. Our policy is to
finance our investments with a capital structure that minimizes financing costs,
maintains financial flexibility, and, with regard to the Utility, complies with
regulatory guidelines. Based on cash provided from operations and our investing
and disposition activities, we may repurchase equity and long-term debt in order
to manage the overall size and balance of our capital structure.

    During 1999, 1998, and 1997, we issued $54 million, $63 million, and
$54 million of common stock, respectively, primarily through the Dividend
Reinvestment Plan and the stock option plan component of the Long-Term Incentive
Program. During 1997, we also issued $1.1 billion of common stock to acquire the
natural gas assets in Texas. During 1999, 1998, and 1997, we declared dividends
on our common stock of $460 million, $466 million, and $485 million,
respectively.

    During 1999, 1998, and 1997, we repurchased $693 million, $1,158 million,
and $804 million of our common stock, respectively. The repurchases made in 1998
and through September 1999 were executed through separate, accelerated share
repurchase programs. As of December 31, 1997, the Board of Directors had
authorized the repurchase of up to $1.7 billion of PG&E Corporation's common
stock on the open market or in negotiated transactions. As part of this
authorization, in January 1998, we repurchased in a specific transaction
37 million shares of common stock. As of December 31, 1998, approximately
$570 million remained available under this repurchase authorization. In
February 1999, we used this remaining authorization to purchase 16.6 million
shares at a cost of $502 million. In connection with this transaction, we
entered into a forward contract with an investment institution. We settled the
forward contract and its additional obligation of $29 million in
September 1999. We used a subsidiary of PG&E Corporation to make this
repurchase, along with subsequent stock repurchases. The stock held by the
subsidiary is treated as treasury stock and reflected as Stock Held by
Subsidiary on the Consolidated Balance Sheet of PG&E Corporation.

    In October 1999, the Board of Directors of PG&E Corporation authorized an
additional $500 million for the purpose of repurchasing shares of the
Corporation's common stock on the open market. This authorization supplements
the approximately $40 million remaining from the amount previously authorized by
the Board of Directors on December 17, 1997. The authorization for share
repurchase extends through September 30, 2001. As of December 31, 1999, through
our wholly owned subsidiary, we repurchased 7.2 million shares, at a cost of
$159 million under this authorization. Any open market purchases will be made by
the wholly owned subsidiary of PG&E Corporation.

    During 1999, our National Energy Group retired $128 million of long-term
debt. This amount includes PG&E GTT's June 1999 redemption of the outstanding
balance of $69 million of its senior notes, which resulted in a gain on
redemption of approximately $1.7 million. In 1998, our National Energy Group
retired $75 million of long-term debt and retired the notes used in the
acquisition of our Australian energy holdings. In 1997, our National Energy
Group issued $30 million and retired $109 million of long-term debt. Also in
1997, we assumed $780 million of long-term debt in connection with the
acquisition of our natural gas assets in Texas.

    We maintain a number of credit facilities to support commercial paper
programs, letters of credit, and other short-term liquidity requirements. PG&E
Corporation maintains two $500 million revolving credit facilities, one of which
expires in November 2000 and the other in 2002. These credit facilities are used
to support the commercial paper program and other liquidity needs. The facility
expiring in 2000 may be extended annually for additional one-year periods upon
agreement with the lending institutions. There was $450 million of commercial
paper outstanding at December 31, 1999. PG&E Corporation introduced a
$200 million Extendible Commercial Note (ECN) program during the third quarter
of 1999. The ECN program supplements our short-term borrowing capability. There
was $76 million of extendible commercial notes outstanding at December 31, 1999,
which are not supported by the credit facilities.

                                       21
<PAGE>

    PG&E Gen maintains two $550 million revolving credit facilities. One
facility expires in August 2000 and the other expires in 2003. The total amount
outstanding at December 31, 1999, backed by the facilities, was $898 million in
commercial paper. Of these loans, $550 million is classified as noncurrent in
the Consolidated Balance Sheet of PG&E Corporation.

    In 1998, USGenNE, a subsidiary of PG&E Gen, established a $100 million
revolving credit facility that expires in 2003. As of December 31, 1999, there
is no outstanding balance on this facility.

    PG&E GT NW maintains a $100 million revolving credit facility that expires
in 2002, but has an annual renewal option allowing the facility to maintain a
three-year duration. PG&E GT NW also maintains a $50 million 364-day credit
facility that expires in 2000, but can be extended for successive 364-day
periods. At December 31, 1999, PG&E GT NW had an outstanding commercial paper
balance of $99 million, which is classified as noncurrent in the Consolidated
Balance Sheet of PG&E Corporation.

    PG&E GTT maintains four separate credit facilities that total $250 million
and are guaranteed by PG&E Corporation. At December 31, 1999, PG&E GTT had
$176 million of outstanding short-term bank borrowings related to these credit
facilities. These lines may be cancelled upon demand and bear interest at each
respective bank's quoted money market rate. The borrowings are unsecured and
unrestricted as to use.

UTILITY:

    In December 1999, 7.6 million shares of the Utility's common stock, with an
aggregate purchase price of $200 million, was purchased by a subsidiary of the
Utility. This purchase is reflected as stock held by subsidiary in the
Consolidated Balance Sheet of Pacific Gas and Electric Company. Earlier in 1999,
the Utility repurchased and cancelled 20 million shares of its common stock from
PG&E Corporation for an aggregate purchase price of $726 million to maintain its
authorized capital structure. In 1999, 1998, and 1997, the Utility declared
dividends on its common stock of $415 million, $300 million, and $699 million,
respectively.

    The Utility's long-term debt that either matured, was redeemed, or was
repurchased during 1999 totaled $654 million. Of this amount, (1) $290 million
related to the Utility's rate reduction bonds maturing, (2) $135 million related
to the Utility's repurchase of mortgage and various other bonds,
(3) $147 million related to maturity of various utility mortgage bonds, and
(4) $82 million related to the maturities and redemption of various of the
Utility's medium-term notes and other debt.

    The Utility's long-term debt that either matured, was redeemed, or was
repurchased during 1998 totaled $1.4 billion. Of this amount, (1) $249 million
related to the Utility's redemption of its 8% mortgage bonds due October 1,
2025, (2) $252 million related to the Utility's repurchase of various other
mortgage bonds, (3) $397 million related to the maturity of the Utility's 5 3/8%
mortgage bonds, (4) $204 million related to the other scheduled maturities of
long-term debt, and (5) $290 million related to rate reduction bonds maturing.

    In 1997, the Utility redeemed or repurchased $225 million of long-term debt
to manage the overall balance of its capital structure. Also in 1997, the
Utility replaced $360 million of fixed interest rate pollution control bonds
with the same amount of variable interest rate pollution control bonds.

    During 1999 and 1997, the Utility did not redeem or repurchase any of its
preferred stock. In 1998, the Utility redeemed its Series 7.44% preferred stock
with a face value of $65 million and its Series 6 7/8% preferred stock with a
face value of $43 million.

    In December 1997, a subsidiary of the Utility issued $2.9 billion of rate
reduction bonds through a special-purpose entity established by the California
Infrastructure and Economic Development Bank. The proceeds were used by the
Utility to retire debt and reduce equity. (See Note 9 of Notes to Consolidated
Financial Statements.)

    The Utility maintains a $1 billion revolving credit facility, which expires
in 2002. The Utility may extend the facility annually for additional one-year
periods upon agreement with the banks. This facility is used to support the
Utility's commercial paper program and other liquidity requirements. The total
amount outstanding at December 31, 1999, backed by this facility, was
$449 million in commercial paper. There were no bank notes outstanding at
December 31, 1999.

CASH FLOWS FROM INVESTING ACTIVITIES

UTILITY:

    The primary uses of cash for investing activities are additions to property,
plant, and equipment, unregulated investments in partnerships, and acquisitions.

    The Utility's estimated capital spending for 2000 is approximately $1.3
billion, excluding capital expenditures for divested fossil and geothermal power
plants. The Utility's capital expenditures were $1,181 million, $1,382 million,
and $1,522 million for the years ended December 31, 1999, 1998, and 1997,
respectively.

    During 1999, the Utility sold three fossil-fueled generation facilities and
its geothermal generation facilities. These sales closed in April and May 1999,
respectively, and generated proceeds of $1,014 million. In 1998, the Utility had
proceeds of $501 million from the sale of three fossil-fueled generation plants.

NATIONAL ENERGY GROUP:

    PG&E Gen is associated with the construction of two natural gas-fueled
combined-cycle power plants, and plans to begin construction on a third plant in
early 2000. These power plants, referred to as "merchant power plants," will
sell power as a commodity in the competitive marketplace. The electricity
generated by these plants will be sold on a wholesale basis to local utilities
and power marketers, including PG&E ET, which, in turn, will sell it to
industrial, commercial, and other electricity customers.

    Millennium Power, a 360-MW power plant located in Massachusetts, is
scheduled to begin commercial service in the fourth quarter of 2000. Lake Road
Generating Plant (Lake Road), an approximately 790-MW power plant located in
Connecticut, is scheduled to begin commercial service in 2001. Lake Road is
being financed through a synthetic lease with a third party owner. PG&E Gen will
operate the plant under an operating lease (See Note 14 of Notes to Consolidated
Financial Statements). La Paloma Generating Plant, an approximately 1,050-MW
power plant, is located in California, and is scheduled to begin commercial
service in 2002. The estimated cost to construct these plants is approximately
$1.4 billion.

    In 1998, PG&E Corporation sold its Australian energy holdings for proceeds
of approximately $126 million. In 1997, PG&E Corporation sold its interest in
International Generating Company, Ltd., resulting in an after-tax gain of
approximately $120 million.

ENVIRONMENTAL MATTERS

    We are subject to laws and regulations established to both maintain and
improve the quality of the environment. Where our properties contain hazardous
substances, these laws and regulations require us to remove those substances or
remedy effects on the environment.

    At December 31, 1999, the Utility has accrued $271 million ($300 million on
an undiscounted basis) for clean-up costs at identified sites. If other
responsible parties fail to pay or expected outcomes change, then these costs
may be as much as $486 million. Of the $271 million, the Utility has recovered
$148 million through rates, including $34 million through depreciation and
expects to recover another $95 million in future rates. Additionally, the
Utility mitigates its cost by seeking recovery from insurance carriers and other
third parties. (See Note 15 of Notes to Consolidated Financial Statements.)

    The cost of the hazardous substance remediation ultimately undertaken by the
Utility is difficult to estimate. A change in the estimate may occur in the near
term due to uncertainty concerning the Utility's responsibility, the complexity
of environmental laws and regulations, and the selection of compliance
alternatives. The Utility estimates the upper limit of the range using
assumptions least favorable to the Utility, based upon a range of reasonably
possible outcomes. Costs may be higher if the Utility is found to be responsible
for clean-up costs at additional sites or expected outcomes change.

    In December 1999, the Utility was notified by the purchaser of its former
Moss Landing power plant that it had identified a cleaning procedure used at the
plant that released heated water from the intake, and that this procedure is not
specified in the plant's National Pollutant Discharge Elimination System (NPDES)
permit issued by the Central Coast Regional Water Quality Control Board (Central
Coast Board). The purchaser notified the Central Coast Board of its findings and
the Central Coast Board requested additional information from the purchaser. The
Utility has initiated an investigation of these activities during the time it
owned the plant. The Central Coast Board has been notified of the investigation
and the results will be presented to the Central Coast Board when the
investigation is complete. If the identified procedure was performed during the
Utility's ownership and was beyond the scope of the relevant NPDES permits, the
Central Coast Board may choose to initiate an enforcement action. If so, the
Utility could be subject to significant penalties. Until the investigation is
complete and the results discussed with the Central Coast Board, it is not
possible to determine whether the Utility will suffer a loss in connection with
this matter or to provide a more detailed estimate of such liability.

YEAR 2000 (Y2K)

    PG&E Corporation successfully transitioned into the Year 2000 without any
Y2K-related service disruptions. There is, however, a risk that some
computer-related problems might not manifest themselves for a period of time and
that supplier or business partner Y2K problems may materialize and have an
adverse impact on our operations.

    As of December 31, 1999, expenditures to address potential Y2K problems
totaled $185 million, of which $93 million is attributed to the Utility.
Included are systems replaced or enhanced for general business purposes and for
which implementation schedules were critical to our Y2K readiness.

INFLATION

    Financial statements, which are prepared in accordance with generally
accepted accounting principles, report operating results in terms of historical
costs and do not evaluate the impact of inflation. Inflation affects our
construction costs, operating expenses, and interest charges. In addition, the
Utility's electric revenues will not reflect the impact of inflation due to the
current electric rate freeze. However, inflation at current levels is not
expected to have a material adverse impact on the Utility's or our financial
position or results of operations.

PRICE RISK MANAGEMENT ACTIVITIES

    We have established a risk management policy that allows derivatives to be
used for both hedging and non-hedging purposes (a derivative is a contract whose
value is dependent on or derived from the value of some underlying asset). We
use derivatives for hedging purposes primarily to offset underlying commodity
price risks. We also participate in markets using derivatives to gather market
intelligence, create liquidity, and maintain a market presence. Such derivatives
include forward contracts, futures, swaps, and options. Net open positions often
exist or are established due to PG&E Corporation's assessment of its response to
changing market conditions. To

                                       24
<PAGE>

the extent that PG&E Corporation has an open position, it is exposed to the risk
that fluctuating market prices may adversely impact its financial results. Our
risk management policy and the trading and risk management policies of our
subsidiaries prohibit the use of derivatives whose payment formula includes a
multiple of some underlying asset.

    We prepare a daily assessment of our portfolio market risk exposure using
value-at-risk and other methodologies that simulate future price movements in
the energy markets to estimate the size and probability of future potential
losses. The quantification of market risk using value-at-risk provides a
consistent measure of risk across diverse energy markets and products. The use
of this methodology requires a number of important assumptions, including the
selection of a confidence level for losses, volatility of prices, market
liquidity, and a holding period.

    We utilize historical data for calculating the price volatility of our
positions and how likely the prices of those positions will move together. The
model includes all derivative and commodity investments in our non-hedging
portfolio and only derivative commodity investments for our hedging portfolio
(but not the related underlying hedged position). We express value-at-risk as a
dollar amount of the potential loss in the fair value of our portfolio based on
a 95 percent confidence level using a one-day liquidation period. Therefore,
there is a 5 percent probability that our portfolio will incur a loss in one day
greater than our value-at-risk. The value-at-risk is aggregated for PG&E
Corporation as a whole by correlating the daily returns of the portfolios for
natural gas, natural gas liquids, and power for the previous 22 trading days.
Our daily value-at-risk for commodity price-sensitive derivative instruments as
of December 31, 1999 and 1998, for non-hedging activities was $4.4 million and
$6.2 million, respectively. Our daily value-at-risk for commodity
price-sensitive derivative instruments as of December 31, 1999 and 1998, for
hedging activities was $30,000 and $210,000, respectively. For the year ended
December 31, 1999, the average, high, and low value-at-risk amounts for
non-hedging activities were $4.3 million, $6.2 million, and $1.3 million,
respectively. The average, high, and low value-at-risk amounts over the same
reporting period for hedging activities were $0.6 million, $1.7 million, and
$0.0 million, respectively. The average, high and low amounts for the reporting
period were computed using the value-at-risk amounts at the beginning of the
reporting period and the four quarter-end amounts.

    Value-at-risk has several limitations as a measure of portfolio risk,
including, but not limited to, underestimation of the risk of a portfolio with
significant options exposure, inadequate indication of the exposure of a
portfolio to extreme price movements, and the inability to address the risk
resulting from intra-day trading activities.

    In June 1999, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 137, "Accounting for
Derivative Instruments and Hedging Activities-Deferral of the Effective Date of
FASB Statement No. 133," which delayed the implementation of SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," by one year to
require adoption in years beginning after June 15, 2000. The Statement permits
early adoption as of the beginning of any fiscal quarter.

    PG&E Corporation expects to adopt SFAS No. 133 no later than January 1,
2001. The Statement will require us to recognize all derivatives, as defined in
the Statement, on the balance sheet at fair value. Derivatives, or any portion
thereof, that are not effective hedges must be adjusted to fair value through
income. If derivatives are effective hedges, depending on the nature of the
hedges, changes in the fair value of derivatives either will be offset against
the change in fair value of the hedged assets, liabilities, or firm commitments
through earnings, or will be recognized in other comprehensive income until the
hedged items are recognized in earnings. We currently are evaluating what the
effect of SFAS No. 133 will be on the earnings and financial position of PG&E
Corporation. However, we already use the mark-to-market method of accounting for
our commodity non-hedging and price risk management activities.

LEGAL MATTERS

    In the normal course of business, both the Utility and PG&E Corporation are
named as parties in a number of claims and lawsuits. (See Note 15 of Notes to
Consolidated Financial Statements for further discussion of significant pending
legal matters.)

                   Notes to Consolidated Financial Statements

NOTE 1: GENERAL

BASIS OF PRESENTATION

    PG&E Corporation became the holding company of Pacific Gas and Electric
Company (the Utility) on January 1, 1997. Prior to that time, the Utility was
the predecessor of PG&E Corporation. Effective with PG&E Corporation's
formation, the Utility's interests in its unregulated subsidiaries were
transferred to PG&E Corporation.

    This is a combined annual report of PG&E Corporation and the Utility.
Therefore, the Notes to Consolidated Financial Statements apply to both PG&E
Corporation and the Utility. PG&E Corporation's consolidated financial
statements include the accounts of PG&E Corporation, the Utility, and PG&E
Corporation's wholly owned and controlled subsidiaries. The Utility's
consolidated financial statements include its accounts as well as those of its
wholly owned and controlled subsidiaries. All significant intercompany
transactions have been eliminated from the consolidated financial statements.
Certain amounts in the prior years' consolidated financial statements have been
reclassified to conform to the 1999 presentation.

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates and assumptions affect the reported amounts of
revenues, expenses, assets, and liabilities and the disclosure of contingencies.
Actual results could differ from these estimates.

    Accounting principles used include those necessary for rate-regulated
enterprises, which reflect the ratemaking policies of the California Public
Utilities Commission (CPUC) and the Federal Energy Regulatory Commission (FERC).

OPERATIONS

    PG&E Corporation is an energy-based holding company headquartered in San
Francisco, California. Its businesses provide energy services throughout North
America. PG&E Corporation's Northern and Central California utility subsidiary,
Pacific Gas and Electric Company, provides natural gas and electric service to
one of every 20 Americans.

    PG&E Corporation's National Energy Group provides energy products and
services throughout North America. The National Energy Group businesses develop,
construct, operate, own, and manage independent power generation facilities that
serve wholesale and industrial customers through PG&E Generating Company, LLC
(formerly U.S. Generating Company, LLC) and its affiliates (collectively, PG&E
Gen); own and operate natural gas pipelines, natural gas storage facilities, and
natural gas processing plants, primarily in the Pacific Northwest and in Texas,
through various subsidiaries of PG&E Corporation (collectively, PG&E Gas
Transmission or PG&E GT); purchase and sell energy commodities and provide risk
management services to customers in major North American markets, including the
other National Energy Group non-utility businesses, unaffiliated utilities,
marketers, municipalities, and large end-use customers through PG&E Energy
Trading--Gas Corporation, PG&E Energy Trading--Power, L.P., and their affiliates
(collectively, PG&E Energy Trading or PG&E ET); and provide competitively priced
electricity, natural gas, and related services to industrial, commercial, and
institutional customers through PG&E Energy Services Corporation (PG&E Energy
Services or PG&E ES). In the fourth quarter of 1999, PG&E Corporation's Board of
Directors approved a plan for the divestiture of PG&E Corporation's Texas
natural gas and natural gas liquids business. Also in the fourth quarter of
1999, PG&E Corporation's Board of Directors approved a plan for the divestiture
of PG&E Corporation's retail energy services.

REGULATION AND STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS (SFAS) NO. 71

    The Utility is regulated by the CPUC, the FERC, and the Nuclear Regulatory
Commission, among others. The gas transmission business in the Pacific Northwest
is regulated by the FERC. The gas transmission business in Texas is regulated by
the Texas Railroad Commission.

    PG&E Corporation and the Utility account for the financial effects of
regulation in accordance with Statement of Financial Accounting Standards (SFAS)
No. 71, "Accounting for the Effects of Certain Types of Regulation." This
statement allows for the deferral as a regulatory asset costs that otherwise
would have been expensed if it is

                                       36
<PAGE>

probable that the costs will be recovered in future regulated revenues. In
addition, SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to be Disposed Of," requires PG&E Corporation and the
Utility to write off regulatory assets when they are no longer probable of
recovery. On an ongoing basis, PG&E Corporation and the Utility review their
regulatory assets and liabilities for the continued applicability of SFAS
No. 71 and the effect of SFAS No. 121.

    Regulatory assets and liabilities are comprised of the following:

(1) See Note 2 of Notes to Consolidated Financial Statements for further
    discussion.

    Regulatory assets and liabilities are amortized over the period that the
costs are reflected in regulated revenues. The majority of the Utility's
regulatory assets are included in generation-related transition costs. The
Utility is amortizing its eligible transition costs, including
generation-related regulatory assets, over the transition period in conjunction
with the available competitive transition charge (CTC) revenues. During 1999,
regulatory assets related to electric industry restructuring decreased by $1,359
million. This decrease reflects the recovery of eligible transition costs of
$806 million through amortization and $553 million through the gain on the sale
of generating plants.

REVENUES AND REGULATORY BALANCING ACCOUNTS

    In connection with electric industry restructuring, use of the Utility's
sales and energy cost balancing accounts for electric utility revenues was
discontinued in 1998. These balancing accounts have been replaced with
regulatory adjustment mechanisms that impact expenses instead of revenues. (See
Note 2.) For gas utility revenues, sales balancing accounts accumulate
differences between authorized and actual base revenues. Further, gas cost
balancing accounts accumulate differences between the actual cost of gas and the
revenues designated for recovery of such costs. The regulatory balancing
accounts accumulate balances until they are refunded to or received from Utility
customers through authorized rate adjustments. Utility revenues included amounts
for services rendered but unbilled at the end of each year.

ACCOUNTING FOR PRICE RISK MANAGEMENT ACTIVITIES

    PG&E Corporation, primarily through its subsidiaries, engages in price risk
management activities for both non-hedging and hedging purposes. PG&E
Corporation conducts non-hedging activities principally through its unregulated
subsidiary, PG&E ET. Derivative and other financial instruments associated with
our electric power, natural gas, natural gas liquids, and related non-hedging
activities are accounted for using the mark-to-market method of accounting.

    Under mark-to-market accounting, PG&E Corporation's non-hedging contracts,
including both physical contracts and financial instruments, are recorded at
market value, which approximates fair value. The market prices used to value
these transactions reflect management's best estimates considering various
factors including market quotes, time value, and volatility factors of the
underlying commitments. The values are adjusted to reflect the potential impact
of liquidating a position in an orderly manner over a reasonable period of time
under present market conditions.

    Changes in the market value of these contract portfolios, resulting
primarily from newly originated transactions and the impact of commodity price
and interest rate movements, are recognized in operating revenues in the

                                       37
<PAGE>

period of change. Unrealized gains and losses of these contract portfolios are
recorded as assets and liabilities, respectively, from price risk management.

    In addition to the non-hedging activities discussed above, PG&E Corporation
may engage in hedging activities using futures, forward contracts, options, and
swaps to hedge the impact of market fluctuations on energy commodity prices,
interest rates, and foreign currencies when there is a high degree of
correlation between price movements in the derivative and the item designated as
being hedged. PG&E Corporation accounts for hedge transactions under the
deferral method. Initially, PG&E Corporation defers unrealized gains and losses
on these transactions and classifies them as assets or liabilities. When the
hedged transaction occurs, PG&E Corporation recognizes the gain or loss in
operating expense. In instances where the anticipated correlation of price
movements does not occur, hedge accounting is terminated and future changes in
the value of the derivative are recognized as gains or losses. If the hedged
item is sold, the value of the associated derivative is recognized in income.

    In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 137, "Accounting for
Derivative Instruments and Hedging Activities--Deferral of the Effective Date of
FASB Statement No. 133," which delayed the implementation of SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," by one year to
require adoption in years beginning after June 15, 2000. The Statement permits
early adoption as of the beginning of any fiscal quarter.

    PG&E Corporation expects to adopt SFAS No. 133 no later than January 1,
2001. The Statement will require PG&E Corporation to recognize all derivatives,
as defined in the Statement, on the balance sheet at fair value. Derivatives, or
any portion thereof, that are not effective hedges must be adjusted to fair
value through income. If derivatives are effective hedges, depending on the
nature of the hedges, changes in the fair value of derivatives either will be
offset against the change in fair value of the hedged assets, liabilities, or
firm commitments through earnings, or will be recognized in other comprehensive
income until the hedged items are recognized in earnings. We currently are
evaluating what effect of SFAS No. 133 will be on the earnings and financial
position of PG&E Corporation. However, we already use the mark-to-market method
of accounting for our commodity non-hedging and price risk management
activities.

    In compliance with regulatory requirements, the Utility manages price risk
independently from the activities in PG&E Corporation's unregulated business.
During 1998, the CPUC authorized Pacific Gas and Electric Company to trade
natural gas-based financial instruments to manage price and revenue risks
associated with its natural gas transmission and storage assets, subject to
certain conditions. Also in 1998, the CPUC authorized the Utility to trade
natural gas-based financial instruments to hedge the gas commodity price swings
in serving core gas customers. In May 1999, the Power Exchange (PX) obtained
FERC approval to operate the "block forward market" which offers parties the
ability to buy and sell contracts to purchase electricity in the future at
prices set in the contracts. The Utility sought and obtained CPUC authority to
participate in the PX block forward market for contracts that call for delivery
of the purchased electricity by October 31, 2000, as well as to recover costs
(such as gains/losses and transaction fees) associated with its participation in
this market.

PROPERTY, PLANT, AND EQUIPMENT

    Plant additions and replacements are capitalized. The capitalized costs
include labor, materials, construction overhead, and capitalized interest or an
allowance for funds used during construction (AFUDC). AFUDC is the estimated
cost of debt and equity funds used to finance regulated plant additions. The
Utility recovers AFUDC in rates through depreciation expense over the useful
life of the related asset. Nuclear fuel inventories are included in property,
plant, and equipment. Stored nuclear fuel inventory is stated at lower of
average cost or market. Nuclear fuel in the reactor is amortized based on the
amount of energy output.

    The original cost of retired plant and removal costs less salvage value is
charged to accumulated depreciation upon retirement of plant in service for the
Utility and the National Energy Group businesses that apply SFAS No. 71. For the
remainder of our National Energy Group business operations, the cost and
accumulated depreciation of property, plant, and equipment retired or otherwise
disposed of are removed from related accounts and included in the determination
of the gain or loss on disposition.

    Property, plant, and equipment is depreciated using a straight-line
remaining-life method. PG&E Corporation's composite depreciation rates were
3.60 percent, 3.89 percent, and 3.45 percent for the years ended December 31,
1999, 1998, and 1997, respectively. The Utility's composite depreciation rates
were 3.41 percent, 3.88 percent, and 3.26 percent for the years ended
December 31, 1999, 1998, and 1997, respectively.

<PAGE>

GAINS AND LOSSES ON REACQUIRED DEBT

    Any gains and losses on reacquired debt associated with regulated operations
that are subject to the provisions of SFAS No. 71 are deferred and amortized
over the remaining original lives of the debt reacquired, consistent with
ratemaking principles. Gains and losses on reacquired debt associated with
unregulated operations are recognized in earnings at the time such debt is
reacquired.

INVENTORIES

    Inventories include material and supplies, gas stored underground, coal, and
fuel oil. Materials and supplies, coal, and gas stored underground are valued at
average cost. Fuel oil is valued by the last-in first-out method.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    Cash equivalents (stated at cost, which approximates market) include working
funds and consist primarily of Eurodollar time deposits, bankers acceptances,
and some commercial paper with original maturities of three months or less.

INCOME TAXES

    PG&E Corporation uses the liability method of accounting for income taxes.
Income tax expense includes current and deferred income taxes resulting from
operations during the year. Tax credits are amortized over the life of the
related property.

    PG&E Corporation files a consolidated federal income tax return that
includes domestic subsidiaries in which its ownership is 80 percent or more. The
Utility and various other subsidiaries are parties to a tax-sharing arrangement
with PG&E Corporation. PG&E Corporation files consolidated state income tax
returns when applicable. The Utility reports taxes on a stand-alone basis.

RELATED PARTY AGREEMENTS

    In accordance with various agreements, the Utility and other subsidiaries
provide and receive various services from their parent, PG&E Corporation.
Services include the Utility's provision of general and administrative services.
The Utility and other subsidiaries receive general and administrative services
and financing from PG&E Corporation. Corporate costs, such as administrative
costs, interest, and income taxes, are allocated to subsidiaries using a variety
of factors, including their share of employees, operating expenses, assets, and
other cost causal methods. Also, the Utility purchases gas commodity and
transmission services from PG&E ET and transmission services from PG&E GT NW.
Intercompany transactions are eliminated in consolidation and no profit results
from these transactions. At December 31, 1999, the Utility has a net
intercompany payable to affiliates of $207 million, of which $163 million
relates to short-term borrowings, including interest. For the years ended
December 31, 1999 and 1998, the Utility's significant related party transactions
are provided in the table below.

CUMULATIVE EFFECT OF CHANGE IN ACCOUNTING METHOD

    Effective January 1, 1999, PG&E Corporation changed its method of accounting
for major maintenance and overhauls at the National Energy Group. Beginning
January 1, 1999, the cost of major maintenance and overhauls, principally at the
PG&E Gen business segment, were accounted for as incurred. Previously, the
estimated cost of major maintenance and overhauls was accrued in advance in a
systematic and rational manner over the period between major maintenance and
overhauls. The change resulted in PG&E Corporation recording income of $12
million net of income tax ($0.03 per share), reflecting the cumulative effect of
the change in accounting principle. The effect on current year results of
operations was immaterial. Accordingly, the unaudited quarterly consolidated
information has been restated. (See "Quarterly Consolidated Financial Data
(Unaudited)" below.)

    The Utility has consistently accounted for major maintenance and overhauls
as incurred.

NOTE 2: THE CALIFORNIA ELECTRIC INDUSTRY

    In 1998, California became one of the first states in the country to
implement electric industry restructuring and establish a competitive market
framework for electric generation. Today, most Californians may continue to
purchase their electricity from investor-owned utilities such as Pacific Gas and
Electric Company, or they may choose to purchase electricity from alternative
generation providers (such as unregulated power generators and unregulated
retail electricity suppliers such as marketers, brokers, and aggregators). For
those customers who have not chosen an alternative generation provider,
investor-owned utilities, such as the Utility, continue to be the generation
providers. Investor-owned utilities continue to provide distribution services to
substantially all customers within their service territories, including
customers who choose an alternative generation provider.

COMPETITIVE MARKET FRAMEWORK

    To create a competitive generation market, a PX and an Independent System
Operator (ISO) began operating on March 31, 1998. The PX provides a competitive
auction process to establish market clearing prices for electricity in the
markets operated by the PX. The ISO schedules delivery of electricity for all
market participants. The Utility continues to own and maintain a portion of the
transmission system, but the ISO controls the operation of the system. Unless or
until the CPUC determines otherwise, the Utility is required to bid or schedule
into the PX and ISO markets all of the electricity generated by its power plants
and electricity acquired under contractual agreements with unregulated
generators. Also, the Utility is required to buy from the PX all electricity
needed to provide service to retail customers that continue to choose the
Utility as their electricity supplier.

    In November 1999, the FERC approved the extension of the ISO's authority to
establish price limitations through 2000. The ISO Board increased the applicable
price limitation to $750 per megawatt-hour (MWh) on October 1, 1999, but has the
option to decrease it to $500 per MWh or make other changes, in view of the
FERC's decision. This limits the amount of volatility that occurs in the
California electricity market. However, the ISO will review the appropriate
level for any price limitations for the summer of 2000 in light of market
redesign efforts now being considered, including changes to reduce uninstructed
deviations from ISO dispatch orders and changes to permit loads to participate
by submitting bids for price responsive demand in energy or ancillary services
markets.

    For the year ended December 31, 1999, and for the period of March 31, 1998
(the PX's establishment date) to December 31, 1998, the cost of electric energy
for the Utility, reflected on the Statement of Consolidated Income, is comprised
of the cost of PX purchases, ancillary services purchased from the ISO, cost of
transmission, and the cost of Utility generation, net of sales to the PX as
follows:

TRANSITION PERIOD, RATE FREEZE, AND RATE REDUCTION

    California's electric industry restructuring established a transition period
during which electric rates remain frozen at 1996 levels (with the exception
that, on January 1, 1998, rates for small commercial and residential customers
were reduced by 10 percent and remain frozen at this reduced level) and
investor-owned utilities may recover their transition costs. Transition costs
are generation-related costs that prove to be uneconomic under the new
competitive structure. The transition period ends the earlier of December 31,
2001, or when the particular utility has recovered its eligible transition
costs.

    Revenues from frozen electric rates provide for the recovery of authorized
Utility costs, including transmission and distribution service, public purpose
programs, nuclear decommissioning, and rate reduction bond debt service. To the
extent the revenues from frozen rates exceed authorized Utility costs, the
remaining revenues constitute the CTC, which recovers the transition costs.
These CTC revenues are being recovered from all Utility distribution customers
and are subject to seasonal fluctuations in the Utility's sales volumes and
certain other factors. As the CTC is collected regardless of the customer's
choice of electricity supplier (i.e., the CTC is non-bypassable), the Utility
believes that the availability of choice to its customers will not have a
material impact on its ability to recover transition costs.

    To pay for the 10 percent rate reduction, the Utility refinanced
$2.9 billion (the expected revenue reduction from the rate decrease) of its
transition costs with the proceeds from the rate reduction bonds. The bonds
allow for the rate reduction by lowering the carrying cost on a portion of the
transition costs and by deferring recovery of a portion of these transition
costs until after the transition period. During the rate freeze, the rate
reduction bond debt service will not increase Utility customers' electric rates.
If the transition period ends before December 31, 2001, the Utility may be
obligated to return a portion of the economic benefits of the transaction to
customers. The timing of any such return and the exact amount of such portion,
if any, have not yet been determined.

TRANSITION COST RECOVERY

    Although most transition costs must be recovered during the transition
period, certain transition costs can be recovered after the transition period.
Except for certain transition costs discussed below, at the conclusion of the
transition period, the Utility will be at risk to recover any of its remaining
generation costs through market-based revenues.

    Transition costs consist of (1) above-market sunk costs (costs associated
with utility generating facilities that are fixed and unavoidable and that were
included in customers' rates on December 20, 1995) and future sunk costs, such
as costs related to plant removal, (2) costs associated with long-term contracts
to purchase power at above-market prices from qualifying facilities and other
power suppliers, and (3) generation-related regulatory assets and obligations.
(In general, regulatory assets are expenses deferred in the current or prior
periods, to be included in rates in subsequent periods.)

    Above-market sunk costs result when the book value of a facility exceeds its
market value. Conversely, below-market sunk costs result when the market value
of a facility exceeds its book value. The total amount of generation facility
costs to be included as transition costs is based on the aggregate of
above-market and below-market values. The above-market portion of these costs is
eligible for recovery as a transition cost. The below-market portion of these
costs will reduce other unrecovered transition costs. These above- and
below-market sunk costs are related to generating facilities that are classified
as either non-nuclear or nuclear sunk costs.

    The Utility cannot determine the exact amount of above-market non-nuclear
sunk costs that will be recoverable as transition costs until the valuation of
the Utility's remaining non-nuclear generating assets, primarily its
hydroelectric generating assets, is completed. The valuation, through appraisal,
sale, or other divestiture, must be completed by December 31, 2001. The value of
seven of the Utility's other non-nuclear generating facilities was determined
when these facilities were sold to third parties. The portion of the sales
proceeds that exceeded the book value of these facilities was used to reduce
other transition costs. On September 30, 1999, the Utility filed an application
with the CPUC to determine the market value of its hydroelectric generating
facilities and related assets through an open, competitive auction. (See
"Generation Divestiture" below.) The Utility plans to use an auction process
similar to the one previously approved by the CPUC and successfully used in the
sale of the Utility's fossil and geothermal plants. If the market value of the
Utility's hydroelectric facilities is determined based upon any method other
than a sale of the facilities to a third party, a material charge to Utility
earnings could result. Any

                                       41
<PAGE>

excess of market value over book value would be used to reduce other transition
costs. (See "Generation Divestiture" below.)

    For nuclear transition costs, revenues provided for transition cost recovery
are based on the accelerated recovery of the investment in Diablo Canyon Nuclear
Power Plant (Diablo Canyon) over a five-year period ending December 31, 2001.
The amount of nuclear generation sunk costs was determined separately through a
CPUC proceeding and was subject to a final verification audit that was completed
in August 1998. The audit of the Utility's Diablo Canyon accounts at
December 31, 1996, resulted in the issuance of an unqualified opinion. The audit
verified that Diablo Canyon sunk costs at December 31, 1996, were $3.3 billion
of the total $7.1 billion construction costs. The independent accounting firm
also issued an agreed-upon special procedures report, requested by the CPUC,
that questioned $200 million of the $3.3 billion sunk costs. The CPUC will
review the results of the audit and may seek to make adjustments to Diablo
Canyon's sunk costs subject to transition cost recovery. At this time, the
Utility cannot predict what actions, if any, the CPUC may take regarding the
audit report.

    Costs associated with the Utility's long-term contracts to purchase electric
power are included as transition costs. Regulation required the Utility to enter
into such long-term agreements with non-utility generators. Prices fixed under
these contracts are now typically above prices for power in wholesale markets
(See Note 14). Over the remaining life of these contracts, the Utility estimates
that it will purchase 299 million MWh of electric power. To the extent that the
individual contract prices are above the market price, the Utility is collecting
the difference between the contract price and the market price from customers,
as a transition cost, over the term of the contract. The contracts expire at
various dates through 2028.

    The total costs under long-term contracts are based on several variables,
including the capacity factors of the related generating facilities and future
market prices for electricity. During 1999, the average price paid under the
Utility's long-term contracts for electricity was 6.3 cents per kilowatt-hour
(kWh). The average cost of electricity purchased at market rates from the PX for
the year ended December 31, 1999, was 3.7 cents per kWh. The average cost of
electricity purchased at market rates from the PX for the period from March 31,
1998, the PX's establishment date, to December 31, 1998, was 3.2 cents per kWh.

    Generation-related regulatory assets and obligations (net generation-related
regulatory assets) are included as transition costs. At December 31, 1999 and
1998, the Utility's generation-related net regulatory assets totaled $4 billion
and $5.4 billion, respectively.

    Certain transition costs can be recovered through a non-bypassable charge to
distribution customers after the transition period. These costs include
(1) certain employee-related transition costs, (2) above-market payments under
existing long-term contracts to purchase power, discussed above, (3) up to
$95 million of transition costs to the extent that the recovery of such costs
during the transition period was displaced by the recovery of electric industry
restructuring implementation costs, and (4) transition costs financed by the
rate reduction bonds. Transition costs financed by the issuance of rate
reduction bonds will be recovered over the term of the bonds. In addition, the
Utility's nuclear decommissioning costs are being recovered through a
CPUC-authorized charge, which will extend until sufficient funds exist to
decommission the nuclear facility. During the rate freeze, the charge for these
costs will not increase Utility customers' electric rates. Excluding these
exceptions, the Utility will write off any transition costs not recovered during
the transition period.

    The Utility is amortizing its transition costs, including most
generation-related regulatory assets, over the transition period in conjunction
with the available CTC revenues. During the transition period, a reduced rate of
return on common equity of 6.77 percent applies to all generation assets,
including those generation assets reclassified to regulatory assets. Effective
January 1, 1998, the Utility started collecting these eligible transition costs
through the non-bypassable CTC and generation divestiture. For the years ended
December 31, 1999 and 1998, regulatory assets related to electric industry
restructuring decreased by $1,359 million and $609 million, respectively, which
reflects the recovery of eligible transition costs.

    During the transition period, the CPUC reviews the Utility's compliance with
accounting methods established in the CPUC's decisions governing transition cost
recovery and the amount of transition costs requested for recovery. The CPUC is
currently reviewing non-nuclear transition costs amortized during 1998 and the
first six months of 1999.

GENERATION DIVESTITURE

    In 1998, the Utility sold three fossil-fueled generation plants for
$501 million. These three fossil-fueled plants had a combined book value at the
time of the sale of $346 million and had a combined capacity of 2,645 megawatts
(MW).

    On April 16, 1999, the Utility sold three other fossil-fueled generation
plants for $801 million. At the time of sale, these three fossil-fueled plants
had a combined book value of $256 million and had a combined capacity of 3,065
MW.

    On May 7, 1999, the Utility sold its complex of geothermal generation
facilities for $213 million. At the time of sale, these facilities had a
combined book value of $244 million and had a combined capacity of 1,224 MW.

    The gains from the sale of the fossil-fueled generation plants were used to
offset other transition costs. Likewise, the loss from the sale of the complex
of geothermal generation facilities is being recovered as a transition cost.

    The Utility has retained a liability for required environmental remediation
related to any pre-closing soil or groundwater contamination at the plants it
has sold.

    On September 30, 1999, the Utility filed an application with the CPUC to
determine the market value of its hydroelectric generating facilities and
related assets through an open, competitive auction. The Utility proposes to use
an auction process similar to the one previously approved by the CPUC and
successfully used in the sale of the Utility's fossil and geothermal plants.
Under the process proposed in the application, another subsidiary of PG&E
Corporation, PG&E Gen, would be permitted to participate in the auction on the
same basis as other bidders.

    The sale of the hydroelectric facilities would be subject to certain
conditions, including the transfer or re-issuance of various permits and
licenses by the FERC and other agencies. In addition, the FERC must approve
assignment of the Utility's Reliability Must Run Contract with the ISO for any
facility subject to such contract. Under the proposed purchase and sale
agreement, the CPUC's approval of the proposed sale on terms acceptable to the
Utility in the Utility's sole discretion is also a condition precedent to the
closing of any sale.

    On January 13, 2000, a scoping memo and ruling was issued that separates the
proceeding into two concurrent phases: one to review the potential environmental
impacts of the proposed auction under the California Environmental Quality Act
and a second to determine whether the Utility's auction proposal, or some other
alternative to the proposal, is in the public interest. The ruling notes that
the divestiture and valuation issues can best be considered after the
environmental impacts of a change in ownership have been reviewed. Potential
bidders will also be able to incorporate the costs of any mitigation measures
that may be required into their bids. The ruling sets a procedural schedule
which calls for a final decision on the Utility's auction proposal by
October 19, 2000, and a final environmental impact report published in
November 2000. The ruling also anticipates that a final CPUC decision approving
the sale would be issued by May 15, 2001. Finally, the ruling prohibits the
Utility from withdrawing its application without express CPUC authority. It is
uncertain whether the CPUC will ultimately approve the Utility's auction
proposal.

    At December 31, 1999, the book value of the Utility's net investment in
hydroelectric generation assets was approximately $0.7 billion, excluding
approximately $0.5 billion of net investment reclassified as regulatory assets.
Any excess of market value over the $0.7 billion book value would be used to
reduce transition costs, including the remaining $0.5 billion of regulatory
assets related to the hydroelectric generation assets. If the market value of
the hydroelectric generation assets is determined by any method other than a
sale of the assets to a third party, or if the winning bidder for any of the
auctioned assets is PG&E Gen, a material charge to Utility earnings could
result. The timing and nature of any such charge is dependent upon the valuation
method and procedure adopted, and the method of implementation. As discussed
below, it is possible that the CPUC will require an interim valuation through an
estimate of market value of the assets prior to transfer, sale or other
divestiture, which could also result in a material charge. While transfer or
sale to an affiliated entity such as PG&E Gen would result in a material charge
to income, neither PG&E Corporation nor the Utility believes that the sale of
any generation facilities to a third party will have a material impact on its
results of operations.

    The Utility's ability to continue recovering its transition costs depends on
several factors, including (1) the continued application of the regulatory
framework established by the CPUC and state legislation, (2) the amount of
transition costs ultimately approved for recovery by the CPUC, (3) the
determined value of the Utility's hydroelectric generation facilities,
(4) future Utility sales levels, (5) future Utility fuel and operating costs,
and

                                       43
<PAGE>

(6) the market price of electricity. Given the current evaluation of these
factors, PG&E Corporation believes that the Utility will recover its transition
costs. However, a change in one or more of these factors could affect the
probability of recovery of transition costs and result in a material charge.

POST-TRANSITION PERIOD

    In October 1999, the CPUC issued a decision in the Utility's post-transition
period ratemaking proceeding. Among other matters, the CPUC's decision addresses
the mechanisms for ending the current electric rate freeze and for establishing
post-transition period accounting mechanisms and rates. The decision requires
Diablo Canyon generation to be priced at prevailing market rates after the
transition period.

    The CPUC decision requires the Utility to provide quarterly forecasts of
when the Utility's rate freeze (i.e., transition period) may end based on
various assumptions regarding energy prices and the book value of the Utility's
remaining generation assets. The Utility is required to notify the CPUC three
months before the earliest forecasted end of its rate freeze and provide draft
tariff language and sample calculations of the rates that would go into effect
when the rate freeze ends. After the Utility completes its transition cost
recovery, it must implement its post-rate-freeze rates.

    The timing of the end of the rate freeze and corresponding transition period
will, in part, depend on the timing of the valuation of the Utility's
hydroelectric generating assets and the ultimate determined value of such assets
since any excess of market value over the assets' book value would be used to
reduce transition costs. If the value of the Utility's hydroelectric generation
assets is significantly higher than the related book value, the transition
period and the rate freeze could end before December 31, 2001, and potentially
could end during 2000. The CPUC is considering the Utility's proposal to auction
its hydroelectric assets, although the CPUC could also

require the Utility to implement an interim valuation of the assets. In another
proceeding (the 1998 Annual Transition Cost Proceeding (ATCP)), a CPUC
administrative law judge issued a proposed decision on January 7, 2000, which
contained a proposed change to the rules previously in place for the
amortization of transition costs. Under the final decision, issued on
February 17, 2000, on a prospective basis the utilities are required to assess
the estimated market value of their remaining non-nuclear generating assets,
including the land associated with those assets, on an aggregate basis at a
value not less than the net book value of those assets and to credit the
Transition Cost Balancing Account (TCBA) with the estimated value. The decision
encourages the utilities to base such estimates on realistic assessments of the
market value of the assets. The final decision did not adopt the proposed
decision's recommendation to establish a new regulatory asset account that would
allow a true-up when the estimated market value is greater than actual market
value. However, the decision states that crediting the TCBA with the aggregate
net book value of the remaining non-nuclear generating assets is a conservative
approach and remedies any concerns regarding the lack of a true-up. The decision
provides that if the estimated market valuation is less than book value for any
individual asset, accelerated amortization of the associated transition costs
will continue until final market valuation of the asset occurs through sale,
appraisal, or other divestiture. If the final value of the assets, determined
through sale, appraisal, or other divestiture, is higher than the estimate, the
excess amount would be used to pay remaining transition costs, if any. The
utilities are required to file the adjusted entries to their respective TCBA
based on the estimated market values with the CPUC by March 9, 2000. The filing
will become effective after appropriate review by the CPUC's Energy Division and
the TCBA entries are subject to review in the next ATCP. If an estimate of the
market value of the non-nuclear generating assets is adopted that exceeds the
aggregate net book value of those assets, a charge to earnings would result.

    After the rate freeze and transition periods end, the Utility must refund to
electric customers any over-collected transition costs (plus interest at the
Utility's authorized rate of return) within one year after the end of the rate
freeze. The Utility also will be prohibited from collecting after the rate
freeze any electric costs incurred during the rate freeze but not recovered
during the rate freeze, including costs that are not classified as transition
costs. Through the end of its rate freeze, the Utility will continue to incur
certain non-transition costs and place those costs into balancing and memorandum
accounts for future recovery. There is a risk that the Utility will be unable to
collect certain non-transition costs that, due to lags in the regulatory cost
approval process, have not been approved for recovery nor collected when the
rate freeze ends. The Utility is unable to predict the amount of such potential
unrecoverable costs.

                                       44

    The CPUC also has established the Purchased Electric Commodity Account for
the Utility to track energy costs after the rate freeze and transition period
end. The CPUC intends to explore other ratemaking issues, including whether
dollar-for-dollar recovery of energy costs is appropriate, in the second phase
of the post-transition electric ratemaking proceeding. There are three primary
options for the future regulatory framework for utility electric energy
procurement cost recovery after the rate freeze: (1) a CPUC-defined procurement
practice, that if followed by the Utility, would pass through costs without the
need for reasonableness reviews, (2) a pass-through of costs subject to
after-the-fact reasonableness reviews, or (3) a procurement incentive mechanism
with rewards and penalties determined based on the Utility's energy purchasing
performance compared to a benchmark. The Utility proposed adoption of either a
defined procurement practice or a procurement incentive mechanism, neither of
which would involve reasonableness reviews. The volatility of earnings and risk
exposure of the Utility related to post-transition period purchases of
electricity is dependent on which of these options, or some other approach, is
adopted.

    After the transition period, the Utility's future earnings from its electric
distribution will be subject to volatility as a result of sales fluctuations.

    PG&E Corporation, primarily through its subsidiaries, engages in price risk
management activities for both non-hedging and hedging purposes. Non-hedging
activities are conducted principally through its unregulated subsidiary, PG&E
ET. In compliance with regulatory requirements, the Utility manages price risk
independently from the activities in PG&E Corporation's unregulated businesses
(see Note 1 for further discussion). The Utility primarily engages in hedging
activities which, noted above, were immaterial for the years ended December 31,
1999 and 1998.

    In valuing its electric power, natural gas, and natural gas liquids
portfolios, PG&E Corporation considers a number of market risks and estimated
costs and continuously monitors the valuation of identified risks and adjusts
them based on present market conditions. Considerable judgment is required to
develop the estimates of fair value; thus, the estimates provided herein are not
necessarily indicative of the amounts that PG&E Corporation could realize in the
current market.

    Generally, exchange-traded futures contracts require deposit of margin cash,
the amount of which is subject to change based on market movement and in
accordance with exchange rules. Margin cash requirements for over-the-counter
financial instruments are specified by the particular instrument and often do
not require margin

                                       46

cash and are settled monthly. Both exchange-traded and over-the-counter options
contracts require payment/ receipt of an option premium at the inception of the
contract. Margin cash for commodities futures and cash on deposit with
counterparties was immaterial at December 31, 1999.

NOTE 4: CONCENTRATIONS OF MARKET AND CREDIT RISK

MARKET RISK

    Market risk is the risk that changes in market prices will adversely affect
earnings and cash flows. PG&E Corporation is primarily exposed to the market
risk associated with energy commodities such as electric power, natural gas, and
natural gas liquids. Therefore, PG&E Corporation's price risk management
activities primarily involve buying and selling fixed-price commodity
commitments into the future. Net open positions often exist or are established
due to PG&E Corporation's assessment of and response to changing market
conditions. To the extent that PG&E Corporation has an open position, it is
exposed to the risk that fluctuating market prices may adversely impact its
financial results.

CREDIT RISK

    The use of financial instruments to manage the risks associated with changes
in energy commodity prices creates exposure resulting from the possibility of
nonperformance by counterparties pursuant to the terms of their contractual
obligation. The counterparties in PG&E Corporation's portfolio consist primarily
of investor-owned and municipal utilities, energy trading companies, financial
institutions, and oil and gas production companies. PG&E Corporation minimizes
credit risk by dealing primarily with creditworthy counterparties in accordance
with established credit approval practices and limits. PG&E Corporation
routinely assesses the financial strength of its counterparties and may require
letters of credit or parental guarantees when the financial strength of a
counterparty is not considered sufficient. PG&E Corporation has experienced no
material losses due to the nonperformance of counterparties in 1999. The credit
exposure of the five largest counterparties comprised approximately
$250 million of the total credit exposure associated with financial instruments
used to manage price risk. Counterparties considered to be investment grade or
higher comprise 70 percent of the total credit exposure.

NOTE 5: ACQUISITIONS AND SALES

    In January 1997, PG&E Corporation acquired Teco Pipeline Company for
$378 million, consisting of $317 million of PG&E Corporation common stock and
the purchase of a $61 million note.

    In April 1997, through one of its wholly owned subsidiaries, PG&E
Corporation sold its interest in International Generating Company, Ltd., which
resulted in an after-tax gain of approximately $120 million.

    In July 1997, PG&E Corporation completed its acquisition of Valero Energy
Corporation's natural gas business and a gas marketing business located in
Texas. PG&E Corporation issued approximately 31 million shares of its common
stock to acquire Valero along with the assumption of $780 million in long-term
debt, equating to a purchase price of approximately $1.5 billion. The
acquisition was accounted for as a purchase and accordingly, the purchase price
has been allocated to the assets acquired and the liabilities assumed based on
estimated fair values.

    In September 1997, PG&E Corporation became the sole owner of PG&E Gen, an
independent power developer, owner, and manager; PG&E Operating Services
Company, PG&E Gen's operations and maintenance affiliate; and USGen Power
Services, L.P., PG&E Gen's power marketing affiliate. Additionally, PG&E
Corporation has acquired all or part of interest in several power projects that
are affiliated with PG&E Gen.

    In July 1998, PG&E Corporation sold its Australian energy holdings. The sale
represents a premium on the price in local currency of PG&E Corporation's 1996
investment in the assets. However, the transaction resulted in a charge of $.06
per share in the second quarter of 1998. This charge was primarily due to the
22 percent currency devaluation of the Australian dollar against the U.S. dollar
during 1998 and 1997.

    In September 1998, PG&E Corporation, through its indirect subsidiary USGen
New England, Inc. (USGenNE), completed the acquisition of a portfolio of
electric generating assets and power supply contracts from the New England
Electric System (NEES). The acquisition has been accounted for using the
purchase method of accounting. Accordingly, the purchase price has been
allocated to the assets purchased and the liabilities assumed based upon an
assessment of the fair values at the date of acquisition.

                                       47
<PAGE>

    Including fuel and other inventories and transaction costs, PG&E
Corporation's financing requirements for this acquisition were approximately
$1.8 billion, funded through an aggregate of $1.3 billion PG&E Gen and USGenNE
debt and a $425 million equity contribution from PG&E Corporation. The net
purchase price has been allocated as follows: (1) electric generating assets of
$2.3 billion classified as property, plant, and equipment, (2) receivable for
support payments of $0.8 billion, and (3) contractual obligations of
$1.3 billion classified as current liabilities and other noncurrent liabilities.
The assets include hydroelectric, coal, oil, and natural gas generation
facilities with a combined generating capacity of 4,000 MW. In addition, USGenNE
assumed 23 multi-year power purchase agreements representing an additional 800
MW of production capacity. USGenNE entered into agreements with NEES as part of
the acquisition, which (1) provide that NEES shall make support payments over
the next 9 years to USGenNE for the purchase power agreements, and (2) require
that USGenNE provide electricity to certain of NEES affiliates under contracts
that expire over the next 3 to 10 years.

    In December 1999, PG&E Corporation's Board of Directors approved a plan to
dispose of PG&E ES, its wholly owned subsidiary, through a sale. As of December
31, 1999, the intended disposal has been accounted for as a discontinued
operation. In connection with this transaction, PG&E Corporation's investment in
PG&E ES was written down to its estimated net realizable value. In addition,
PG&E Corporation provided a reserve for anticipated losses through the date of
sale. The total provision for discontinued operations was $58 million, net of
income taxes of $36 million. While there is no definite sales agreement, it is
expected that the disposition will be completed in 2000. The amounts that PG&E
Corporation will ultimately realize from this disposal could be materially
different from the amounts assumed in arriving at the estimated loss on disposal
of the discontinued operations. The PG&E ES business segment generated net

    On January 27, 2000, PG&E Corporation's National Energy Group signed a
definitive agreement with El Paso Field Services Company (El Paso) providing for
the sale to El Paso, a subsidiary of El Paso Energy Corporation, of the stock of
PG&E Gas Transmission, Texas Corporation and PG&E Gas Transmission Teco, Inc.
(collectively, PG&E GTT). The consideration to be received by the National
Energy Group includes $279 million in cash subject to a working capital
adjustment, the assumption by El Paso of debt having a book value of $624
million, and other liabilities associated with PG&E GTT.

    In 1999, PG&E Corporation recognized a charge against earnings of $890
million after-tax, or $2.42 per share, to reflect PG&E GTT's assets at their
fair market value. The composition of the pre-tax charge is as follows: (1) an
$819 million write down of net property, plant, and equipment, (2) the
elimination of the unamortized portion of goodwill, in the amount of $446
million, and (3) an accrual of $10 million representing selling costs.

    Proceeds from the sale will be used to retire short-term debt associated
with PG&E GTT's operations and for other corporate purposes. Closing of the
sale, which is expected in the first half of 2000, is subject to approval under
the Hart Scott Rodino Act.

NOTE 6: COMMON STOCK

PG&E CORPORATION

    PG&E Corporation has authorized 800 million shares of no-par common stock of
which 384 million and 383 million shares were issued as of December 31, 1999 and
1998, respectively.

    During the years ended December 31, 1999 and 1998, PG&E Corporation
repurchased $693 million and $1,158 million of its common stock, respectively.
The repurchases in 1998 and through September 1999 were executed through
separate, accelerated share repurchase programs. Under the 1999 agreement, PG&E
Corporation repurchased in a specific transaction 16.6 million shares of its
common stock at a cost of $502 million. In connection with this transaction,
PG&E Corporation entered into a forward contract with an investment institution.
PG&E Corporation settled the forward contract and its additional obligation of
$29 million in September 1999. A wholly owned subsidiary of PG&E Corporation
made this repurchase, along with subsequent stock repurchases. The stock held by
the subsidiary is treated as treasury stock and reflected as stock held by
subsidiary on the Consolidated Balance Sheet of PG&E Corporation.

    In October 1999, the Board of Directors of PG&E Corporation authorized an
additional $500 million for the purpose of repurchasing shares of the
Corporation's common stock on the open market. This authorization supplements
the approximately $40 million remaining from the amount previously authorized by
the Board of Directors on December 17, 1997. The authorization for share
repurchase extends through September 30, 2001. As of December 31, 1999, a
subsidiary of PG&E Corporation has repurchased 7.2 million shares at a cost of
$159 million under this authorization.

UTILITY

    All of the Utility's outstanding common stock is held by PG&E Corporation
and a subsidiary of the Utility. In connection with the formation of the holding
company, all of the Utility's then-outstanding common stock was converted on a
share-for-share basis to PG&E Corporation common stock.

    The Utility has authorized 800 million shares of $5 par value common stock
of which 321 million and 341 million shares were issued as of December 31, 1999
and 1998, respectively.

    Prior to December 1999, the Utility repurchased 20 million shares of its
common stock from PG&E Corporation for an aggregate purchase price of
$726 million to maintain its authorized capital structure. In December 1999,
7.6 million shares of the Utility's common stock, with an aggregate purchase
price of $200 million, was purchased by a subsidiary of the Utility. This
purchase is reflected as stock held by subsidiary in the Consolidated Balance
Sheet of Pacific Gas and Electric Company.

    The CPUC requires the Utility to maintain its CPUC-authorized capital
structure, potentially limiting the amount of dividends the Utility may pay PG&E
Corporation. In 1999, the Utility was in compliance with its CPUC-authorized
capital structure.

NOTE 7: PREFERRED STOCK AND UTILITY OBLIGATED MANDATORILY REDEEMABLE PREFERRED
SECURITIES OF TRUST HOLDING SOLELY UTILITY SUBORDINATED DEBENTURES

PREFERRED STOCK OF UTILITY

    The Utility has authorized 75 million shares of $25 par value preferred
stock which may be issued as redeemable or nonredeemable preferred stock. At
December 31, 1999 and 1998, the Utility had issued and outstanding 5,784,825
shares of nonredeemable preferred stock.

    At December 31, 1999 and 1998, the Utility had issued and outstanding
5,973,456 shares of redeemable preferred stock. The Utility's redeemable
preferred stock is subject to redemption at the Utility's option, in whole or in
part, if the Utility pays the specified redemption price plus accumulated and
unpaid dividends through the redemption date. Annual dividends and redemption
prices per share at December 31, 1999, range from $1.09 to $1.76 and from $25.75
to $27.25, respectively. In 1998, the Utility redeemed its Series 7.44%
preferred stock with a face value of $65 million. Also in 1998, the Utility
redeemed its Series 6 7/8% preferred stock with a face value of $43 million.

    The Utility's redeemable preferred stock with mandatory redemption
provisions consists of 3 million shares of the 6.57% series and 2.5 million
shares of the 6.30% series at December 31, 1999. The 6.57% series and 6.30%
series may be redeemed at the Utility's option beginning in 2002 and 2004,
respectively, at par value plus accumulated and unpaid dividends through the
redemption date. These series of preferred stock are subject to mandatory
redemption provisions entitling them to sinking funds providing for the
retirement of stock outstanding.

    Holders of the Utility's nonredeemable preferred stock 5%, 5.5%, and 6%
series have rights to annual dividends per share ranging from $1.25 to $1.50.

    Dividends on all preferred stock are cumulative. All shares of preferred
stock have voting rights and equal preference in dividend and liquidation
rights. Upon liquidation or dissolution of the Utility, holders of preferred
stock would be entitled to the par value of such shares plus all accumulated and
unpaid dividends, as specified for the class and series.

PREFERRED STOCK OF THE NATIONAL ENERGY GROUP

    Preferred stock of the National Energy Group consists of $57 million of
preferred stock issued by a subsidiary of PG&E Gen. The preferred stock, with
$100 par value, has a stated dividend of $3.35 per share, per quarter, and is
redeemable when there is an excess of available cash. There were 549,594 shares
outstanding at December 31, 1999 and 1998.

UTILITY OBLIGATED MANDATORILY REDEEMABLE PREFERRED SECURITIES OF TRUST HOLDING
SOLELY UTILITY SUBORDINATED DEBENTURES

    The Utility, through its wholly owned subsidiary, PG&E Capital I (Trust),
has outstanding 12 million shares of 7.90% cumulative quarterly income preferred
securities (QUIPS), with an aggregate liquidation value of $300 million.
Concurrent with the issuance of the QUIPS, the Trust issued to the Utility
371,135 shares of common securities with an aggregate liquidation value of
$9 million. The Trust in turn used the net proceeds from the QUIPS offering and
issuance of the common stock securities to purchase subordinated debentures
issued by the Utility with a face value of $309 million, an interest rate of
7.9%, and a maturity date of 2025. These subordinated debentures are the only
assets of the Trust. Proceeds from the sale of the subordinated debentures were
used to redeem and repurchase higher-cost preferred stock.

    The Utility's guarantee of the QUIPS, considered together with the other
obligations of the Utility with respect to the QUIPS, constitutes a full and
unconditional guarantee by the Utility of the Trust's contractual obligations
under the QUIPS issued by the Trust. The subordinated debentures may be redeemed
at the Utility's option beginning in 2000 at par value plus accrued interest
through the redemption date. The proceeds of any redemption will be used by the
Trust to redeem QUIPS in accordance with their terms.

    Upon liquidation or dissolution of the Utility, holders of these QUIPS would
be entitled to the liquidation preference of $25 per share plus all accrued and
unpaid dividends thereon to the date of payment.

UTILITY

FIRST AND REFUNDING MORTGAGE BONDS:

    First and refunding mortgage bonds are issued in series and bear annual
interest rates ranging from 5.85 percent to 8.80 percent. All real properties
and substantially all personal properties of the Utility are subject to the lien
of the bonds, and the Utility is required to make semi-annual sinking fund
payments for the retirement of the bonds. Additional bonds may be issued subject
to CPUC approval, up to a maximum total amount outstanding of $10 billion,
assuming compliance with indenture covenants for earnings coverage and available
property balances as security.

    The Utility redeemed or repurchased $281 million and $501 million of the
bonds in 1999 and 1998, respectively, with interest rates ranging from
6.25 percent to 8.80 percent. These bonds were to mature from 2002 to 2026.

    Included in the total of outstanding bonds at December 31, 1999 and 1998,
are $345 million of bonds held in trust for the California Pollution Control
Financing Authority (CPCFA) with interest rates ranging from 5.85 percent

                                       51
<PAGE>

to 6.625 percent and maturity dates ranging from 2009 to 2023. In addition to
these bonds, the Utility holds long-term pollution control loan agreements with
the CPCFA as described below.

POLLUTION CONTROL LOAN AGREEMENTS:

    Pollution control loan agreements from the CPCFA totaled $1,348 million at
December 31, 1999 and 1998. Interest rates on the loans vary with average annual
interest rates. For 1999 the interest rates ranged from 2.36 percent to
3.39 percent. These loans are subject to redemption by the holder under certain
circumstances. These loans are secured primarily by irrevocable letters of
credit which mature in 2000 through 2003.

NATIONAL ENERGY GROUP

    Long-term debt of the National Energy Group consists of first mortgage bonds
and other secured and unsecured obligations.

    The first mortgage notes are comprised of three series due annually through
2009, and are secured by mortgages and security interests in the natural gas
transmission and natural gas processing facilities and other real and personal
property of PG&E GTT. The mortgage indenture requires semi-annual payments with
one-half of each interest payment and one-fourth of each annual principal
payment escrowed quarterly in advance. The mortgage indenture also contains
covenants that restrict the ability of PG&E GTT to incur additional indebtedness
and precludes cash distributions if certain cash flow coverages are not met. In
January 2000, PG&E GTT obtained an amendment that provides PG&E GTT the ability
to redeem in whole or in part, its Mortgage Notes, including the premium set
forth in the Mortgage Note Indenture, anytime after January 1, 2000. These notes
will be assumed by the buyer of PG&E GTT (see Note 5).

    Other long-term debt consists of project financing associated with
unregulated generation facilities, premiums, and other loans.

REPAYMENT SCHEDULE

    At December 31, 1999, PG&E Corporation's combined aggregate amounts of
maturing long-term debt and sinking fund requirements, for the years 2000
through 2004, are $592 million, $480 million, $1,363 million, $1,271 million,
and $470 million, respectively. The Utility's share of those maturities and
sinking fund requirements is $465 million, $374 million, $1,117 million,
$664 million, and $392 million, respectively.

NOTE 9: RATE REDUCTION BONDS

    In December 1997, PG&E Funding LLC (SPE), a special-purpose entity wholly
owned by the Utility, issued $2.9 billion of rate reduction bonds to the
California Infrastructure and Economic Development Bank Special Purpose Trust
PG&E-1 (Trust), a special-purpose entity. The terms of the bonds generally
mirror the terms of the pass-through certificates issued by the Trust. The
proceeds of the rate reduction bonds were used by the SPE to purchase from the
Utility the right, known as "transition property," to be paid a specified amount
from a non-bypassable tariff levied on residential and small commercial
customers which was authorized by the CPUC pursuant to state legislation.

    The rate reduction bonds have maturities ranging from 6 months to 8 years,
and bear interest at rates ranging from 6.15 percent to 6.48 percent. The bonds
are secured solely by the transition property and there is no recourse to the
Utility or PG&E Corporation.

    At December 31, 1999, $2.3 billion of rate reduction bonds were outstanding.
The combined expected principal payments on the rate reduction bonds for the
years 2000 through 2004 are $290 million for each year.

    While the SPE is consolidated with the Utility for purposes of these
financial statements, the SPE is legally separate from the Utility. The assets
of the SPE are not available to creditors of the Utility or PG&E Corporation,
and the transition property is not legally an asset of the Utility or PG&E
Corporation.

NOTE 10: CREDIT FACILITIES

PG&E CORPORATION

    At December 31, 1999 and 1998, PG&E Corporation had borrowed $2,148 million
and $2,298 million, respectively, under various credit facilities discussed
below. $649 million and $654 million of these borrowings at December 31, 1999
and 1998, respectively, are classified as long-term debt. (See Note 8.) The
weighted average interest rate on the short-term borrowings was 5.4 percent and
5.6 percent for 1999 and 1998, respectively.

                                       52
<PAGE>

    PG&E Corporation maintains two $500 million revolving credit facilities, one
of which expires in November 2000 and the other in 2002. These credit facilities
are used to support the commercial paper program and other liquidity needs. The
facility expiring in 2000 may be extended annually for additional one-year
periods upon agreement with the lending institutions. There was $450 million and
$683 million of commercial paper outstanding at December 31, 1999 and 1998,
respectively. PG&E Corporation introduced a $200 million Extendible Commercial
Note (ECN) program during the third quarter of 1999. The ECN program supplements
our short-term borrowing capability. There was $76 million of ECNs outstanding
at December 31, 1999, which are not supported by the credit facilities.

UTILITY

    The Utility maintains a $1 billion revolving credit facility which expires
in 2002. The facility may be extended annually for additional one-year periods
upon agreement with the banks. This facility is used to support the Utility's
commercial paper program and other liquidity requirements. The total amount
outstanding at December 31, 1999, backed by this facility, was $449 million in
commercial paper. The total amount outstanding at December 31, 1998, backed by
this facility was $567 million in commercial paper and $101 million of bank
notes.

NATIONAL ENERGY GROUP

    PG&E Gen maintains two $550 million revolving credit facilities. One
facility expires in August 2000 and the other expires in 2003. The amount
outstanding at December 31, 1999 and 1998, backed by the facilities, was
$898 million and $233 million, respectively in commercial paper. Also
outstanding at December 31, 1998, was a $540 million eurodollar loan drawn on
one of the revolving credit facilities, which was subsequently paid off in 1999.
At December 31, 1999 and 1998, $550 million of these loans is classified as
noncurrent in the consolidated balance sheet.

    In 1998, USGenNE, a subsidiary of PG&E Gen, established a $100 million
revolving credit facility that expires in 2003. No amounts were outstanding at
December 31, 1999.

    PG&E GT NW maintains a $100 million revolving credit facility that expires
in 2002, but has an annual renewal option allowing the facility to maintain a
three-year duration. PG&E GT NW also maintains a $50 million 364-day credit
facility which expires in 2000, but may be extended for successive 364-day
periods. No amounts were outstanding under either of these credit facilities at
December 31, 1999. At December 31, 1999 and 1998, PG&E GT NW had an outstanding
commercial paper balance of $99 million and $104 million, respectively, which is
classified as noncurrent in the Consolidated Balance Sheet of PG&E Corporation.

    PG&E GTT maintains four separate credit facilities that total $250 million
and are guaranteed by PG&E Corporation. At December 31, 1999, PG&E GTT had
$176 million of outstanding short-term bank borrowings related to these credit
facilities. At December 31, 1998, PG&E GTT had $70 million of outstanding
short-term bank borrowings related to two credit facilities. These lines may be
cancelled upon demand and bear interest at each respective bank's quoted money
market rate. The borrowings are unsecured and unrestricted as to use.

NOTE 11: NUCLEAR DECOMMISSIONING

    Decommissioning of the Utility's nuclear power plants is scheduled to begin
for ratemaking purposes in 2015 with scheduled completion in 2034. Nuclear
decommissioning means to safely remove nuclear facilities from service and
reduce residual radioactivity to a level that permits termination of the Nuclear
Regulatory Commission license and release of the property for unrestricted use.

    The estimated total obligation for nuclear decommissioning costs, based on a
1997 site study, is $1.6 billion in 1999 dollars (or $5.1 billion in future
dollars). This estimate assumes after-tax earnings on the tax-qualified and
non-tax-qualified decommissioning funds of 6.34 percent and 5.39 percent,
respectively, as well as a future annual escalation rate of 5.5 percent for
decommissioning costs. The decommissioning cost estimates are based on the plant
location and cost characteristics for the Utility's nuclear plants. Actual
decommissioning costs are expected to vary from this estimate because of changes
in assumed dates of decommissioning, regulatory requirements, technology, and
costs of labor, materials, and equipment. The estimated total obligation is
being recognized proportionately over the license term of each facility.

    For the year ended December 31, 1999, nuclear decommissioning costs
recovered in rates were $26.5 million. For the years ended December 31, 1998 and
1997, nuclear decommissioning costs recovered in rates were $33 million per
year, respectively. The CPUC has established a Nuclear Decommissioning Cost
Triennial

                                       53
<PAGE>

Proceeding to review, every three years, updated decommissioning cost estimates
and to establish the annual trust contribution, absent general rate cases.

    At December 31, 1999, the total nuclear decommissioning obligation accrued
was $1.3 billion and is included in the balance sheet classification of
accumulated depreciation and decommissioning. Decommissioning costs recovered in
rates are placed in external trust funds. These funds along with accumulated
earnings will be used exclusively for decommissioning and cannot be released
from the trust funds until authorized by the CPUC.

    The following table provides a summary of fair value, based on quoted market
prices, of these nuclear decommissioning funds:

    The proceeds received from sales of securities were $1.7 billion in 1999,
and $1.4 billion in 1998 and 1997. The gross realized gains on sales of
securities held as available-for-sale were $59 million, $52 million, and
$40 million in 1999, 1998, and 1997, respectively. The gross realized losses on
sales of securities held as available-for-sale were $60 million, $39 million,
and $24 million in 1999, 1998, and 1997, respectively. The cost of debt and
equity securities sold is determined by specific identification.

    Under the Nuclear Waste Policy Act of 1982, the Department of Energy (DOE)
is responsible for the permanent storage and disposal of spent nuclear fuel. The
Utility has signed a contract with the DOE to provide for the disposal of spent
nuclear fuel and high-level radioactive waste from the Utility's nuclear power
facilities. The DOE's current estimate for an available site to begin accepting
physical possession of the spent nuclear fuel is 2010. At the projected level of
operation for Diablo Canyon, the Utility's facilities are sufficient to store
on-site all spent fuel produced through approximately 2006. It is likely that an
interim or permanent DOE storage facility will not be available for Diablo
Canyon's spent fuel by 2006. The Utility is examining options for providing
additional temporary spent fuel storage at Diablo Canyon or other facilities,
pending disposal or storage at a DOE facility.

NOTE 12: EMPLOYEE BENEFIT PLANS

    Several of PG&E Corporation's subsidiaries provide noncontributory defined
benefit pension plans for their employees and retirees. In addition, these
subsidiaries provide contributory defined benefit medical plans for certain
retired employees and their eligible dependents and noncontributory defined
benefit life insurance plans for certain retired employees (referred to
collectively as other benefits). For both pension and other benefit plans, the
Utility's plan represents substantially all of the plan assets and the benefit
obligation. Therefore, all descriptions and assumptions are based on the
Utility's plans. The schedules below aggregate all of the plans employed by PG&E
Corporation's subsidiaries.

    The Utility's share of the plans' assets in excess of the benefit obligation
for pensions in 1999 and 1998 was $3,344 million and $2,134 million,
respectively. The Utility's share of the prepaid benefit cost for the pensions
in 1999 and 1998 was $556 million and $301 million, respectively.

    The plan assets of the Utility exceeded its share of the benefit obligation
for other benefits by $167 million and $24 million in 1999 and 1998,
respectively. The Utility's share of the accrued benefit liability for other
benefits in 1999 and 1998 was $22 million and $26 million, respectively.

    Unrecognized prior service costs and the net gains are amortized on a
straight-line basis over the average remaining service period of active plan
participants. The transition obligations for pension benefits and other benefits
are being amortized over 17.5 years from 1987.

    Net benefit income (cost) was as follows:

    The Utility's share of the net benefit income for pensions in 1999, 1998,
and 1997 was $253 million, $215 million, and $123 million, respectively.

    The Utility's share of the net benefit cost for other benefits in 1999,
1998, and 1997 was $9 million, $12 million, and $38 million, respectively.

    Net benefit income (cost) is calculated using an expected long-term rate of
return on plan assets of 9.0 percent. The difference between actual and expected
long-term rate of return on plan assets is included in net amortization and
deferral and is considered in the determination of future net benefit income
(cost). In 1999, 1998, and 1997, actual return on plan assets exceeded expected
return.

    In conformity with SFAS No. 71, regulatory adjustments have been recorded in
the income statement and balance sheet of the Utility which reflect the
difference between Utility pension income determined for accounting purposes and
Utility pension income determined for ratemaking, which is based on a funding
approach.

    The CPUC also has authorized the Utility to recover the costs associated
with its other benefit plans for 1993 and beyond. Recovery is based on the
lesser of the annual accounting costs or the annual contributions on a
tax-deductible basis to the appropriate trusts.

    The following actuarial assumptions were used in determining the plans'
funded status and net benefit income (cost). Year-end assumptions are used to
compute funded status, while prior year-end assumptions are used to compute net
benefit income (cost).

    The assumed health care cost trend rate for 2000 is approximately
8.5 percent, grading down to an ultimate rate in 2006 of approximately
6.0 percent. The assumed health care cost trend rate can have a significant
effect on the amounts reported for health care plans. A one percentage point
change would have the following effects:

LONG-TERM INCENTIVE PROGRAM

    PG&E Corporation maintains a Long-term Incentive Program (Program) that
provides for grants of stock options to eligible participants with or without
associated stock appreciation rights and dividend equivalents. As of
December 31, 1999, 34,389,230 shares of PG&E Corporation common stock have been
authorized for award with 15,779,821 shares still available under this program.
Shares granted in 1999, 1998 and 1997, had approximate values of $23 million,
$27 million, and $12 million, respectively, using the Black-Scholes valuation
method. In addition, PG&E Corporation granted 9,712,900 shares on January 3,
2000 at an option price of $19.8125 and 18,000 shares on February 1, 2000 at an
option price of $22.1875, the then-current market prices.

    Outstanding stock options become exercisable on a cumulative basis at
one-third each year commencing two years from the date of grant and expire ten
years and one day after the date of grant. Shares outstanding at December 31,
1999, had option prices ranging from $16.75 to $34.25 and a weighted-average
remaining contractual life of 7.8 years. As permitted under SFAS No. 123
"Accounting for Stock-Based Compensation," PG&E Corporation applies Accounting
Board Opinion No. 25 in accounting for the program. As the exercise price of all
stock options are equal to their fair market value at the time the options are
granted, PG&E Corporation

does not recognize any compensation expense related to the program using the
intrinsic value based method. Had compensation expense been recognized using the
fair value based method under SFAS No. 123, PG&E Corporation's consolidated
earnings would have been reduced by $16 million, $10 million and $4 million in
1999, 1998, and 1997, respectively.

    Historically, the benefits of certain temporary differences have been
utilized to reduce the Utility's customers rates. Accordingly, a regulatory
asset has been recorded reflecting the pre-tax amount that will be recovered
from customers as the temporary difference reverses. In connection with the
California electric restructuring plan, the Utility is collecting the regulatory
asset over four years.

    During 1999, PG&E Corporation generated a capital loss carryforward of
approximately $225 million, which will expire in 2005. A valuation allowance of
approximately $75 million has been recorded reflecting the estimated net
realizable value of this capital loss carryforward.

NOTE 14: COMMITMENTS

UTILITY

LETTERS OF CREDIT AND SURETY BONDS:

    The Utility uses $409 million in standby letters of credit and surety bonds
to secure future workers' compensation liabilities.

RESTRUCTURING TRUST GUARANTEES:

    Tax-exempt restructuring trusts were established to oversee the development
of the operating framework for the competitive generation market in California.
(See Note 2.) The CPUC has authorized California utilities to guarantee bank
loans of up to $85 million to be used by the trusts for this purpose. Under the
CPUC authorization, the Utility's remaining guarantee is for up to a maximum of
$38 million of the loan. The remaining bank loan will be repaid and the
guarantee removed when the trust obtains proceeds from permanent financing or
rate recovery.

POWER PURCHASE CONTRACTS:

    By federal law, the Utility is required to purchase electric energy and
capacity provided by independent power producers that are qualifying facilities
(QFs) under the Public Utilities Regulatory Policies Act of 1978 (PURPA). The
CPUC established a series of QF long-term power purchase contracts and set the
applicable terms, conditions, price options, and eligibility requirements.

    Under these contracts, the Utility is required to make payments only when
energy is supplied or when capacity commitments are met. Costs associated with
these contracts are eligible for recovery by the Utility as transition costs
through the collection of the nonbypassable CTC. The Utility's contracts with
these power producers expire on various dates through 2028. Deliveries from
these power producers account for approximately 23 percent of the Utility's 1999
electric energy requirements, and no single contract accounted for more than
five percent of the Utility's energy needs.

    The Utility has negotiated with several QFs for early termination of their
power purchase contracts. For other contracts, the Utility has negotiated with
QFs to refrain from producing energy during the remaining term of the higher
fixed energy price period under their contract (a "buy-down") or to curtail
energy production for shorter periods of time (a "curtailment"). At
December 31, 1999, the total discounted future payments due under the
renegotiated contracts that are subject to early termination, buy-down, or
curtailment was $16 million, of which

                                       58
<PAGE>

$6.6 million has been recovered in rates and the Utility expects to recover the
remaining $9.4 million in future rates.

    The Utility also has contracts with various irrigation districts and water
agencies to purchase hydroelectric power. Under these contracts, the Utility
must make specified semi-annual minimum payments whether or not any energy is
supplied (subject to the supplier's retention of the FERC's authorization) and
variable payments for operation and maintenance costs incurred by the suppliers.
These contracts expire on various dates from 2004 to 2031. Costs associated with
these contracts to purchase power are eligible for recovery by the Utility as
transition costs through the collection of the nonbypassable CTC. At
December 31, 1999, the undiscounted future minimum payments under these
contracts were $32.7 million for each of the years 2000 through 2004 and a total
of $247 million for periods thereafter. Irrigation district and water agency
deliveries in the aggregate account for approximately 5.8 percent of the
Utility's 1999 electric energy requirements.

    The amount of energy received and the total payments made under all of these
power purchase contracts were:

NATURAL GAS TRANSPORTATION COMMITMENTS:

    The Utility has long-term gas transportation service contracts with various
Canadian and interstate pipeline companies. These agreements include provisions
for payment of fixed demand charges for reserving firm capacity on the
pipelines. The total demand charges that the Utility will pay each year may
change due to changes in tariff rates. The total demand and volumetric
transportation charges the Utility paid under these agreements were
$97 million, $113 million, and $255 million in 1999, 1998, and 1997,
respectively. These amounts include payments made by the Utility to PG&E GT NW
of $47 million, $49 million, and $49 million in 1999, 1998, and 1997,
respectively, which are eliminated in the consolidated financial statements of
PG&E Corporation.

    As a result of regulatory changes, the Utility no longer procures gas for
most of its industrial and larger commercial (noncore) customers, resulting in a
decrease in the Utility's need for capacity on these pipelines. Despite these
changes, the Utility continues to procure gas for substantially all of its
residential and smaller commercial (core) customers and its noncore customers
who choose bundled service. To the extent that the Utility's current capacity
holdings exceed demand for gas transportation by its customers, the Utility will
continue its efforts to broker such excess capacity.

NATIONAL ENERGY GROUP

POWER PURCHASE CONTRACTS:

    As a part of the acquisition of a portfolio of electric generating assets
and power supply contracts from NEES (see Note 5), NEES transferred to PG&E Gen
contractual rights and duties under several power purchase contracts with
third-party independent power producers. At December 31, 1999, these agreements
provided for an aggregate

                                       59
<PAGE>

of 470 MW of capacity. Under the transfer agreement, PG&E Gen is required to pay
to NEES amounts due to the third-party power producers under the power purchase
contracts. PG&E Gen's payment obligations to NEES are reduced by NEES's monthly
payment obligation, payable in monthly installments from September 1998 through
January 2008. In certain circumstances, NEES, with the consent of PG&E Gen, will
make a full or partial lump-sum accelerated payment of the monthly payment
obligation to such party as PG&E Gen may direct. The approximate dollar amounts
under these agreements are as follows:

STANDARD OFFER AGREEMENTS:

    As a part of the acquisition of a portfolio of electric generating assets
and power supply contracts from NEES (see Note 5), PG&E Gen entered into
agreements to supply the electric capacity and energy necessary for certain of
NEES affiliates to meet their obligations to provide standard offer service. The
agreements to provide standard offer service range in length from 3 to 10 years.
The price per MWh is standard for all agreements. For the year ended
December 31, 1999, the standard offer service price paid generators was $0.035
per Kwh for generation.

OPERATING LEASES:

    PG&E Corporation and the National Energy Group have entered into various
long-term lease commitments.

    PG&E Gen has an agreement to lease Lake Road under a five-year operating
lease agreement which is extendible. The lease term will commence upon the
completion of the construction of a gas-fired generating facility, which is
anticipated to be mid-2001. The minimum obligations under this lease cannot be
determined until the commencement of the lease because the minimum rent payments
are based on the final cost to complete the facility. The approximate
obligations below are based on the current estimated total cost of the facility.

    USGenNE entered into a $479 million sale-and-leaseback transaction whereby
USGenNE sold and leased back its Bear Swamp facility to a third party. The
related lease is being accounted for as an operating lease. The rental expense
under this lease in 1999 was $2 million.

    PG&E Gen leases the Pittsfield facility from General Electric Credit
Corporation. The rental expense for this facility in 1999 was $28 million.

                                       60

    PG&E GTT has an operating lease commitment in connection with gas storage.
The term of the gas storage facility lease and related arrangements run through
January 2008 and subject to certain conditions, has one or more optional renewal
periods of five years each at fair market value. The rental expense for this gas
storage facility in 1999 was approximately $10 million.

    PG&E Corporation and our National Energy Group have leases for office space
primarily located in California, Maryland, Oregon, Massachusetts, and Texas. For
the year ended December 31, 1999, rent expense for these facilities amounted to
$27 million.

NOTE 15: CONTINGENCIES

NUCLEAR INSURANCE

    The Utility has insurance coverage for property damage and business
interruption losses as a member of Nuclear Electric Insurance Limited (NEIL).
Under this insurance, if a nuclear generating facility suffers a loss due to a
prolonged accidental outage, the Utility may be subject to maximum retrospective
assessments of $15 million (property damage) and $4 million (business
interruption), in each case per policy period, in the event losses exceed the
resources of NEIL.

    The Utility has purchased primary insurance of $200 million for public
liability claims resulting from a nuclear incident. The Utility has secondary
financial protection which provides an additional $9.3 billion in coverage,
which is mandated by federal legislation. It provides for loss sharing among
utilities owning nuclear generating facilities if a costly incident occurs. If a
nuclear incident results in claims in excess of $200 million, then the Utility
may be assessed up to $176 million per incident, with payments in each year
limited to a maximum of $20 million per incident.

ENVIRONMENTAL REMEDIATION

    The Utility may be required to pay for environmental remediation at sites
where it has been or may be a potentially responsible party under the
Comprehensive Environmental Response, Compensation and Liability Act and similar
state environmental laws. These sites include former manufactured gas plant
sites, power plant sites, and sites used by it for the storage or disposal of
potentially hazardous materials. Under federal and California laws, it may be
responsible for remediation of hazardous substances, even if it did not deposit
those substances on the site.

    The Utility records a liability when site assessments indicate remediation
is probable and a range of reasonably likely clean-up costs can be estimated.
The Utility reviews its remediation liability quarterly for each identified
site. The liability is an estimate of costs for site investigations,
remediation, operations and maintenance, monitoring, and site closure. The
remediation costs also reflect (1) current technology, (2) enacted laws and
regulations, (3) experience gained at similar sites, and (4) the probable level
of involvement and financial condition of other potentially responsible parties.
Unless there is a better estimate within this range of possible costs, the
Utility records the lower end of this range.

    The cost of the hazardous substance remediation ultimately undertaken by the
Utility is difficult to estimate. A change in estimate may occur in the near
term due to uncertainty concerning the Utility's responsibility, the complexity
of environmental laws and regulations, and the selection of compliance
alternatives. At December 31, 1999, the Utility expects to spend $300 million
for hazardous waste remediation costs at identified sites, including

                                       61
<PAGE>

divested fossil-fueled power plants. The Utility had an accrued liability of
$271 million and $296 million at December 31, 1999 and 1998, respectively,
representing the discounted value of these costs.

    Of the $271 million accrued liability discussed above, the Utility has
recovered $148 million through rates, including $34 million through
depreciation, and expects to recover another $95 million in future rates.
Additionally, the Utility is mitigating its costs by obtaining recovery of its
costs from insurance carriers and from other third parties as appropriate.

    Environmental remediation at identified sites may be as much as
$486 million if, among other things, other potentially responsible parties are
not financially able to contribute to these costs or further investigation
indicates that the extent of contamination or necessary remediation is greater
than anticipated. The Utility estimated this upper limit of the range of costs
using assumptions least favorable to the Utility, based upon a range of
reasonably possible outcomes. Costs may be higher if the Utility is found to be
responsible for clean-up costs at additional sites or outcomes change.

    Further, as discussed in "Generation Divestiture" above, the Utility will
retain the pre-closing remediation liability associated with divested generation
facilities.

    PG&E Corporation believes the ultimate outcome of these matters will not
have a material impact on its or the Utility's financial position or results of
operations.

LEGAL MATTERS

CHROMIUM LITIGATION:

    Several civil suits are pending against the Utility in California state
court. The suits seek an unspecified amount of compensatory and punitive damages
for alleged personal injuries resulting from alleged exposure to chromium in the
vicinity of the Utility's gas compressor stations at Hinkley, Kettleman, and
Topock, California. Currently, there are claims pending on behalf of
approximately 900 individuals.

    The Utility is responding to the suits and asserting affirmative defenses.
The Utility will pursue appropriate legal defenses, including statute of
limitations or exclusivity of workers' compensation laws, and factual defenses,
including lack of exposure to chromium and the inability of chromium to cause
certain of the illnesses alleged.

    PG&E Corporation believes that the ultimate outcome of these matters will
not have a material adverse impact on its or the Utility's financial position or
results of operations.

TEXAS FRANCHISE FEE LITIGATION:

    In connection with PG&E Corporation's acquisition of Valero Energy
Corporation, now known as PG&E Gas Transmission Texas (PG&E GTT), PG&E GTT
succeeded to the litigation described below.

    PG&E GTT and various of its affiliates are defendants in at least two class
action suits and five separate suits filed by various Texas cities. Generally,
these cities allege, among other things, that (1) owners or operators of
pipelines occupied city property and conducted pipeline operations without the
cities' consent and without compensating the cities, and (2) the gas marketers
failed to pay the cities for accessing and utilizing the pipelines located in
the cities to flow gas under city streets. Plaintiffs also allege various other
claims against the defendants for failure to secure the cities' consent. Damages
are not quantified.

    In 1998, a jury trial was held in the separate suit brought by the City of
Edinburg (the City). This suit involved, among other things, a particular
franchise agreement entered into by a former subsidiary of PG&E GTT (now owned
by Southern Union Gas Company (SU)) and the City and certain conduct of the
defendants. On December 1, 1998, based on the jury verdict, the court entered a
judgment in the City's favor, and awarded damages of $5.3 million, and
attorneys' fees of up to $3.5 million plus interest. The court found that
various PG&E GTT and SU defendants were jointly and severally liable for
$3.3 million of the damages and all the attorneys' fees. Certain PG&E GTT
subsidiaries were found solely liable for $1.4 million of the damages. The court
did not clearly indicate the extent to which the PG&E GTT defendants could be
found liable for the remaining damages. The PG&E GTT defendants are in the
process of appealing the judgment.

    In connection with the certification of a class in one of the class actions,
the court ordered notice to be sent to all potential class members and setting
an opt-out deadline of December 31, 1997. Notices were mailed to approximately
159 Texas cities. Fewer than 20 cities opted out by the deadline. In
November 1999, the court signed an order dismissing from the class 42 cities
because it determined there was no pipeline presence and no

                                       62

past or present sales activity, leaving 106 cities in the class. The parties in
this class action are negotiating the terms of a settlement agreement. The
settlement proposal contemplates, among other things, that the PG&E Corporation
defendants would pay $12.2 million to the class cities, inclusive of attorney
fees, reduced by amounts attributable to opt-out cities. The defendants retain
the right to reject the settlement if the settlement proposal is not approved by
certain key cities and by 80% of the plaintiff class. Although a significant
number of the 106 cities in the plaintiff class already have either approved the
settlement or adopted resolutions to pass the ordinance, certain key cities have
not yet approved the settlement. The settlement is also subject to court
approval. On January 27, 2000, the court approved the settlement proposal and
established a 14-day period whether to accept the negotiated settlement terms or
opt out of the settlement. The Court also stated that if Corpus Christi does not
accept the settlement proposal, it will be placed in a sub-class, whose claims
will not be finalized as part of the settlement approval. Corpus Christi has the
right to opt out of this subclass.

    PG&E Corporation believes that the ultimate outcome of these matters will
not have a material adverse impact on its financial position or its results of
operations. As discussed above in Note 5, in January 2000, PG&E Corporation's
National Energy Group signed a definitive agreement to sell the stock of PG&E
Gas Transmission, Texas Corporation and PG&E Gas Transmission Teco, Inc. The
buyer will assume all liabilities associated with the cases described above.

RECORDED LIABILITY FOR LEGAL MATTERS:

    In accordance with SFAS No. 5, PG&E Corporation makes a provision for a
liability when both it is probable that a liability has been incurred and the
amount of the loss can be reasonably estimated. These provisions are reviewed
quarterly and adjusted to reflect the impacts of negotiations, settlements,
rulings, advice of legal counsel, and other information and events pertaining to
a particular case. In the fourth quarter of 1999, PG&E Corporation reduced the
amount of the recorded liability for legal matters associated with a court
approved settlement proposal and other settlement discussions of certain matters
described above. Approximately $55 million of the adjustments, arising from a
pre-acquisition contingency related to a purchased business, are reflected in
"Other income, net" in PG&E Corporation's Statement of Consolidated Income. The
following table reflects the current year's activity to the recorded liability
for legal matters:

NOTE 16: GENERAL RATE CASE

    In December 1997, the Utility filed its 1999 application with the CPUC
During the GRC process, the CPUC examines the Utility's costs to determine the
amount the Utility may charge customers for base revenues (non-fuel related
costs). The Utility requested distribution revenue increases to maintain and
improve natural gas and electric distribution reliability, safety, and customer
service. The requested revenues, as updated, included an increase of $445
million in electric base revenues and an increase of $377 million in natural gas
base revenues over the 1998 authorized revenues.

    The Utility received a final decision on its 1999 GRC application on
February 17, 2000. This final decision increased electric distribution revenues
by $163 million and gas distribution revenues by $93 million, as compared to
revenues authorized for 1998. This revenue increase is retroactive to
January 1, 1999. The impact of these increases resulted in an increase in
earnings of $153 million, or $0.42 per share, and was reflected in the fourth
quarter of 1999.

NOTE 17: SEGMENT INFORMATION

    PG&E Corporation has identified four reportable operating segments. The
Utility is one reportable operating segment and the other three are part of PG&E
Corporation's National Energy Group. These four reportable operating segments
provide different products and services and are subject to different forms of
regulation or jurisdictions. PG&E Corporation's reportable segments are
described below.

PG&E Corporation's Board of Directors approved a plan for the divestiture of
PG&E Corporation's Texas natural gas and natural gas liquids business. Also in
the fourth quarter of 1999, PG&E Corporation's Board of Directors approved a
plan for the divestiture of PG&E Corporation's retail energy services, conducted
through PG&E ES. PG&E ES had total assets of $197 million, $202 million, and
$60 million, as of December 31, 1999, 1998, and 1997, respectively.

NOTE 18: FAIR VALUE OF FINANCIAL INSTRUMENTS

    PG&E Corporation estimates fair value of its financial instruments based on
quoted market prices, where available. Fair value of the Utility's rate
reduction bonds, and Utility obligated manditorily redeemable preferred
securities of trust holding solely Utility subordinated debentures are all
determined based on quoted market prices. Fair value of the Utility's preferred
stock with mandatory provisions is based on indicative market prices. Where
quoted or indicative market prices are not available, the estimated fair value
is determined using other valuation techniques (for example, the present value
of future cash flows). Most of PG&E Corporation's and the Utility's debt is
determined using quoted market prices, but the fair value of a small portion of
Utility debt is determined using the present value of future cash flows. The
carrying value of PG&E Corporation's short-term borrowings approximates fair
value.

    At December 31, 1999 and 1998, PG&E Corporation's carrying amount and ending
fair value of its financial instruments are:

(1) In the fourth quarter 1999, the National Energy Group adopted a plan to
    dispose of the PG&E ES segment. This planned transaction has been accounted
    for as a discontinued operation. Results of operations of PG&E ES have been
    excluded from continuing operations for all periods presented. The operating
    loss and net loss of PG&E ES for the quarters ending March 31, June 30, and
    September 30, 1999, were $15 million and $8 million, $23 million and
    $14 million, and $20 million and $12 million, respectively. The operating
    loss and net loss for PG&E ES for the quarters ending March 31, June 30, and
    September 30, 1998, were $17 million and $11 million, $22 million and
    $14 million, and $27 million and $15 million, respectively.

(2) Amounts have been restated to reflect the change in accounting for major
    maintenance and overhauls at the National Energy Group (see Note 1 of the
    Notes to Consolidated Financial Statements), and reclassification of PG&E ES
    operating results to discontinued operations (see above). The accounting
    change resulted in a cumulative effect being recorded as of January 1, 1999,
    of $12 million ($0.03 per share), net of income taxes of $8 million.
    Operating income previously reported for 1999 was $442 million,
    $454 million, and $492 million for each of the first three quarters,
    respectively. Net income previously reported for 1999 was $156 million
    ($0.42 per share), $180 million ($0.49 per share), and $183 million ($0.50
    per share) for the same periods.

(3) In the fourth quarter 1999, the Utility recorded the effects of the outcome
    of the GRC. This resulted in an increase of $256 million in operating income
    and an increase of $153 million in net income. Additionally, the National
    Energy Group recorded an after-tax charge of $890 million reflecting PG&E
    GTT's assets at their fair market value. (See Notes 5 and 16 of the Notes to
    Consolidated Financial Statements.)

                          INDEPENDENT AUDITORS' REPORT

To the Boards of Directors and Shareholders of
PG&E Corporation and Pacific Gas and Electric Company

    We have audited the accompanying consolidated balance sheets of PG&E
Corporation and subsidiaries and of Pacific Gas and Electric Company and
subsidiaries as of December 31, 1999, and the related statements of consolidated
income, cash flows, and common stock equity of PG&E Corporation and the related
statements of consolidated income, cash flows, and stockholders' equity of
Pacific Gas and Electric Company for the year then ended. These financial
statements are the responsibility of management of PG&E Corporation and of
Pacific Gas and Electric Company. Our responsibility is to express an opinion on
these financial statements based on our audits. The consolidated financial
statements for the years ended December 31, 1998 and 1997 were audited by other
auditors whose report, dated February 8, 1999, expressed an unqualified opinion
on those statements.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, such 1999 financial statements present fairly, in all
material respects, the consolidated financial position of PG&E Corporation and
Pacific Gas and Electric Company as of December 31, 1999, and the results of
their consolidated operations and cash flows for the year then ended in
conformity with generally accepted accounting principles.

    As discussed in Note 1 of the Notes to Consolidated Financial Statements, in
1999 PG&E Corporation changed its method of accounting for major maintenance and
overhauls.

              RESPONSIBILITY FOR CONSOLIDATED FINANCIAL STATEMENTS

    At both PG&E Corporation and Pacific Gas and Electric Company (the Utility)
management is responsible for the integrity of the accompanying consolidated
financial statements. These statements have been prepared in accordance with
generally accepted accounting principles. Management considers materiality and
uses its best judgment to ensure that such statements reflect fairly the
financial position, results of operations, and cash flows of PG&E Corporation
and the Utility.

    PG&E Corporation and the Utility maintain systems of internal controls
supported by formal policies and procedures which are communicated throughout
PG&E Corporation and the Utility. These controls are adequate to provide
reasonable assurance that assets are safeguarded from material loss or
unauthorized use and that necessary records are produced for the preparation of
consolidated financial statements. There are limits inherent in all systems of
internal controls, based on recognition that the costs of such systems should
not exceed the benefits to be derived. PG&E Corporation and the Utility believe
that their systems of internal control provide this appropriate balance. PG&E
Corporation management also maintains a staff of internal auditors who evaluate
the adequacy of, and assess the adherence to, these controls, policies, and
procedures for all of PG&E Corporation, including the Utility.

    Both PG&E Corporation's and the Utility's 1999 consolidated financial
statements have been audited by Deloitte & Touche LLP, PG&E Corporation's
independent auditors. The audit includes consideration of internal accounting
controls and performance of tests necessary to support an opinion. The auditors'
report contains an independent informed judgment as to the fairness, in all
material respects, of reported results of operations and financial position.

    The Audit Committee of the Board of Directors for PG&E Corporation meets
regularly with management, internal auditors, and Deloitte & Touche, jointly and
separately, to review internal accounting controls and auditing and financial
reporting matters. The internal auditors and Deloitte & Touche LLP have free
access to the Audit Committee, which consists of five outside directors. The
Audit Committee has reviewed the financial data contained in this report.

    PG&E Corporation and the Utility are committed to full compliance with all
laws and regulations and to conducting business in accordance with high
standards of ethical conduct. Management has taken the steps necessary to ensure
that all employees and other agents understand and support this commitment.
Guidance for corporate compliance and ethics is provided by an officers' Ethics
Committee and by a Legal Compliance and Business Ethics organization. PG&E
Corporation and the Utility believe that these efforts provide reasonable
assurance that each of their operations is conducted in conformity with
applicable laws and with their commitment to ethical conduct.

Dear Sirs/Madams:

We have audited the consolidated financial statements of PG&E Corporation as of
December 31, 1999 and for the year then ended, included in your Annual Report on
Form 10-K to the Securities and Exchange Commission, and have issued our report
thereon dated March 3, 2000.  Note 1 to such financial statements contains a
description of your change during the year ended December 31, 1999 to account
for major maintenance and overhauls expenditures at power production facilities
as incurred.  In our judgment, such change is to an alternative accounting
principle that is preferable under the circumstances.


Yours truly,

/s/  DELOITTE & TOUCHE LLP
