Ladies and Gentlemen:

         PG&E Corporation, a California corporation (the "Company"), proposes,
subject to the terms and conditions stated herein, to issue and sell
$280,000,000 aggregate principal amount of its 7.50% Convertible Subordinated
Notes, in the respective principal amounts set forth in Schedule 1 hereto
(together with any PIK Securities (as defined in the Indenture) that may be
issued thereon, the "Securities"), to Lehman Brothers Inc., Jackson Investment
Fund Ltd., Citadel Credit Trading Ltd. and Citadel Equity Fund Ltd. (each
individually, a "Purchaser" and collectively, the "Purchasers"). This is to
confirm the agreement between the Company and the Purchasers concerning the
offer, issue and sale of the Securities.

         The Securities will be offered and sold to the Purchasers without being
registered under the Securities Act of 1933, as amended, and the rules and
regulations of the Securities and Exchange Commission (the "Commission")
thereunder (collectively, the "Securities Act"), in reliance upon an exemption
therefrom. It is understood by the parties hereto that if the



conversion price of the Securities meets the requirements of Rule 144A(d)(3)(i)
promulgated under the Securities Act, the Securities will be eligible to be
resold pursuant to Rule 144A.

         The Securities will be issued pursuant to an indenture (the
"Indenture"), the form of which is contained in Annex A hereof, dated as of the
date hereof (the "Closing Date"), between the Company and U.S. Bank, N.A., as
Trustee (the "Trustee"). The Securities will be convertible into shares of
common stock, no par value (the "Common Stock"), of the Company (such shares,
the "Conversion Shares") on the terms, and subject to the conditions, set forth
in the Indenture.

         Holders of the Securities (including the Purchasers and their
respective transferees) will be entitled to the benefits of a Resale
Registration Rights Agreement, dated as of the Closing Date, between the Company
and the Purchasers (the "Registration Rights Agreement"), the form of which is
contained in Annex B hereof, pursuant to which the Company will agree, among
other things, to use its best efforts to file with the Commission a shelf
registration statement pursuant to Rule 415 under the Securities Act (the
"Registration Statement") covering the resale of the Conversion Shares, and to
use its best efforts to cause the Registration Statement to be declared
effective within the time periods specified therein.

         This Agreement, the Indenture, the Securities and the Registration
Rights Agreement are referred to herein collectively as the "Transaction
Documents".

             1. Representations, Warranties and Agreements of the Company. The
Company represents, warrants to and agrees with, each of the Purchasers

         amended, and the rules and regulations of the Commission thereunder
         (collectively, the "Exchange Act"), when they were filed with the
         Commission, conformed in all material respects to the requirements of
         the Exchange Act and none of such documents (collectively, the
         "Exchange Act Documents") contained any untrue statement of a material
         fact or omitted to state any material fact required to be stated
         therein or necessary in order to make the statements therein, in light
         of the circumstances under which they were made, not misleading.

                                       3



         constitute such a default, in the due performance or observance of any

         the Company in accordance with their terms, subject to the effects of
         bankruptcy, insolvency, fraudulent conveyance, reorganization,

         Purchasers, it will be a legally valid and binding agreement of the
         Company, enforceable against the Company in accordance with its terms,
         except as the enforceability thereof may be limited by bankruptcy,
         insolvency, fraudulent conveyance, reorganization, moratorium and other
         similar laws relating to or affecting creditors' rights generally.

         Loans under, and as defined in, the Credit Agreement, repayment of
         indebtedness and transaction expenses;

                   (i) The Company will take all actions and cause its
         Subsidiaries to take all actions reasonably required to comply in all
         material respects with applicable Utility Regulations and each order
         issued pursuant thereto; provided that, the foregoing shall not prevent
         the Company or a Subsidiary from challenging the validity or effect of
         any Utility Regulation or order in any proceeding provided the manner
         of such challenge could not reasonably be expected to cause a Material
         Adverse Effect. For purposes of this Section 3(i), "Utility Regulation"

         or any agency or political subdivision of the foregoing which is

         provided that, such term shall not include laws, regulations or rules
         of general applicability with respect to protection of the environment,
         hazardous waste, or public health or safety; and

                   (j) The Company will not register the Securities pursuant to
         Section 12 of the Exchange Act, unless it is required pursuant to the
         requirements of the Exchange Act to do so as a result of the number of

            6. Representations, Warranties and Agreements of the Purchasers.
Each Purchaser, represents and warrants to, and agrees with, the Company,
severally and not jointly and with respect to only itself (except with respect
to the representation and warranty set forth in Section 6(f) which shall only be
made by Lehman Brothers Inc.), as follows:

                   (a) Such Purchaser is knowledgeable, sophisticated and
         experienced in business and financial matters and qualifies as an
         "accredited investor" as defined in Rule 501(a) of Regulation D and as
         a "qualified institutional buyer" as defined in Rule 144A under the
         Securities Act.

                   (b) Such Purchaser has been afforded access to information
         about the Company and the financial condition, results of operations,
         business, property, management and prospects of the Company sufficient
         to enable it to evaluate its investment in the Securities. Such
         Purchaser and its advisors, if any, have been afforded the opportunity
         to ask questions of the Company. Such Purchaser has sought such
         accounting, legal and tax advice as it has considered necessary to make
         an informed investment decision with respect to its acquisition of the
         Securities. Neither such access or questions nor any other due
         diligence investigations conduction by such Purchaser or its advisors,
         if any, or representatives shall modify, amend or affect such
         Purchaser's right to rely on the Company's representations, warranties
         and agreements contained in this Agreement, the Indenture, the
         Registration Rights Agreement and the Securities.

                   (c) Such Purchaser understands that its investment in the
         Securities involves a high degree of risk. Such Purchaser is able to
         bear the economic risk of its investment in the Securities and is
         presently able to afford the complete loss of such investment.

                   (d) Such Purchaser is acquiring the Securities solely for its
         own account and not as a nominee or agent for any other person and not
         with a view to any distribution thereof that violates the Securities
         Act or the securities laws of any State of the United States or any
         applicable jurisdiction; provided, however, that by making the
         representations herein, such Purchaser does not agree to hold any of
         the Securities for any minimum or other specific term and reserves the
         right to dispose of the Securities at any time in accordance with or
         pursuant to a registration statement or an exemption under the
         Securities Act.

                                       13



                   (e) Lehman Brothers Inc. has not offered or sold the
         Securities by means of any form of general solicitation or general
         advertising within the meaning of Rule 502(c) of Regulation D,
         including (i) any advertisement, article, notice or other communication
         published in any newspaper, magazine or similar medium or broadcast
         over television or radio, or (ii) any seminar or meeting whose
         attendees have been invited by any general solicitation or general
         advertising in the United States.

                   (f) Such Purchaser has all necessary power and authority to
         execute and deliver this Agreement and perform its obligations
         hereunder; and this Agreement and the transactions contemplated hereby
         have been duly authorized by such Purchaser; assuming due
         authorization, execution and delivery by the Company, this Agreement
         constitutes a legally valid and binding agreement of such Purchaser,
         enforceable against such Purchaser in accordance with its terms,
         subject to the effects of bankruptcy, insolvency, fraudulent
         conveyance, reorganization, moratorium and other similar laws relating
         to or affecting creditors' rights generally.

                   (g) Such Purchaser is a resident of that jurisdiction
         specified in its address for notices set forth below the signature of
         such Purchaser where it appears on the signature page(s) of this
         Agreement.

                   (h) Such Purchaser is not acquiring the Securities with
         assets of any "employee benefit plan" (within the meaning of Section
         3(3) of the Employee Retirement Income Security Act of 1974, as amended
         ("ERISA")) that is subject to Title I of ERISA or Section 4975 of the
         Internal Revenue Code of 1986, as amended.

                   (i) Assuming the capitalization of the Company set forth in
         its most recent report filed under the Exchange Act, such Purchaser,
         together with its "affiliates" (as defined in Rule 144 promulgated
         under the Securities Act), is the beneficial owner (as defined in Rule
         13d-3 promulgated under the Exchange Act) of not more than 4.9% of the
         outstanding shares of Common Stock immediately after the purchase of
         the Securities hereunder.

         The Company and, for purposes of the opinions to be delivered to you
pursuant to Section 5 hereof, counsel to the Company, General Counsel to the
Company and counsel to the Purchasers, will rely upon the accuracy and truth of
the foregoing representations as to factual matters and agreements and each
Purchaser hereby consents to such reliance.

                                       14



            7. Conditions of the Company's Obligations. The obligations of the
Company to each of the Purchasers hereunder are subject to the accuracy, of the
representations and warranties of such Purchaser contained herein, to the
performance by such Purchaser of its obligations hereunder, the delivery by such
Purchaser of the Purchase Price in consideration of the Securities being
purchased by such Purchaser and to the closing with respect to such Purchaser of
the transactions contemplated by the Credit Agreement.

            8. Indemnification.

                   (a) The Company shall indemnify and hold harmless each
         Purchaser who is acquiring Securities hereunder, its officers and
         employees and each person, if any, who controls such Purchaser within
         the meaning of the Securities Act, from and against any loss, claim,
         damage or liability, joint or several, or any action in respect thereof
         (including, but not limited to, any loss, claim, damage, liability or
         action relating to purchases and sales of the Securities)
         ("Liabilities"), to which such Purchaser, officer, employee or
         controlling person may become subject, insofar as such Liability arises
         out of, or is based upon, any breach of any representation or warranty
         made by it in this Agreement, and shall reimburse such Purchaser and
         each such officer, employee or controlling person promptly upon demand
         for any legal or other expenses reasonably incurred by such Purchaser,
         officer, employee or controlling person in connection with
         investigating or defending or preparing to defend against any such
         Liability as such expenses are incurred. The foregoing indemnity
         agreement is in addition to any liability which the Company may
         otherwise have to such Purchaser or to any officer, employee or
         controlling person of such Purchaser.

                   (b) Promptly after receipt by a Purchaser who is acquiring
         Securities hereunder under this Section 8 of notice of any claim or the
         commencement of any action, such Purchaser shall, if a claim in respect
         thereof is to be made against the Company under this Section 8, notify
         the Company in writing of the claim or the commencement of that action;
         provided, however, that the failure to notify the Company shall not
         relieve it from any liability which it may have under this Section 8
         except to the extent it has been materially prejudiced by such failure
         and, provided, further, that the failure to notify the Company shall
         not relieve it from any liability which it may have to such Purchaser
         otherwise than under this Section 8. If any such claim or action shall
         be brought against such Purchaser, and it shall notify the Company
         thereof, the Company shall be entitled to participate therein and, to
         the extent that it wishes, jointly with any other similarly notified
         indemnifying party, to assume the defense thereof with counsel
         satisfactory to such Purchaser. After notice from the Company to such
         Purchaser of its election to assume the defense of such claim or
         action, the Company shall not be liable to such Purchaser under this
         Section 8 for any legal or other expenses subsequently incurred by such
         Purchaser in connection with the defense thereof other than reasonable
         costs of investigation; provided, however, that such Purchaser shall
         have the right to employ separate counsel to represent jointly such
         Purchaser and its respective officers, employees and controlling
         persons who may be subject to liability arising out of any claim in
         respect of which indemnity may be sought by such Purchaser against the
         Company under this Section 8 if, in the reasonable judgment of such
         Purchaser it is advisable for such Purchaser and such officers,
         employees and controlling persons to be jointly represented

                                       15



         by separate counsel, and in that event the fees and expenses of such
         separate counsel shall be paid by the Company. No indemnifying party
         shall, (i) without the prior written consent of the indemnified parties
         (which consent shall not be unreasonably withheld), settle or
         compromise or consent to the entry of any judgment with respect to any
         pending or threatened claim, action, suit or proceeding in respect of
         which indemnification or contribution may be sought hereunder (whether
         or not the indemnified parties are actual or potential parties to such
         claim or action) unless such settlement, compromise or consent includes
         an unconditional release of each indemnified party from all liability
         arising out of such claim, action, suit or proceeding, or (ii) be
         liable for any settlement of any such action effected without its
         written consent (which consent shall not be unreasonably withheld), but
         if settled with its written consent or if there be a final judgment of
         the plaintiff in any such action, the Company agrees to indemnify and
         hold harmless any indemnified party from and against any loss or
         liability by reason of such settlement or judgment.

                   (c) To the extent that the undertaking in this Section 8 by
         the Company may be unenforceable for any reason, the Company shall make
         the maximum contribution to the payment and satisfaction of the
         Purchasers who are acquiring Securities hereunder which is permissible
         under applicable law.
