                            a market sale. See "Special Factors--Purpose of the

                            July 21, 1997 (the "August 1997 Dividend"). A
                            tender of Shares pursuant to the Offer will not
                            deprive a shareholder of his or her right to
                            receive the August 1997 Dividend regardless of when
                            such tender is made. Holders of Shares tendered
                            into and purchased pursuant to the Offer will not

                                 INTRODUCTION
 
  PSE invites the holders of the Series of Preferred listed on the front cover
of this Offer to Purchase to tender any and all of their Shares for purchase
at the purchase price per share listed on the front cover of this Offer to
Purchase which is applicable to the Shares tendered, net to the seller in
cash, upon the terms and subject to the conditions set forth herein and in the
Letter of Transmittal for the Series of Preferred tendered. As to each Series
of Preferred, this Offer to Purchase, together with the applicable Letter of
Transmittal, constitutes the "Offer." See "Terms of the Offer--Extension;
Termination; Amendments" and "--Certain Conditions of the Offer."
 
  THE OFFER FOR SHARES OF EACH SERIES OF PREFERRED IS INDEPENDENT OF THE OFFER
FOR SHARES OF ANY OTHER SERIES OF PREFERRED.
 
  NEITHER PSE, ITS BOARD OF DIRECTORS NOR ANY OF ITS OFFICERS MAKES ANY
RECOMMENDATION TO ANY SHAREHOLDER AS TO WHETHER TO TENDER ALL OR ANY SHARES.
EACH SHAREHOLDER MUST MAKE HIS OR HER OWN DECISION AS TO WHETHER TO TENDER
SHARES AND, IF SO, HOW MANY SHARES TO TENDER.
 
  EACH SERIES OF PREFERRED HAS ITS OWN LETTER OF TRANSMITTAL, AND ONLY THE
APPLICABLE LETTER OF TRANSMITTAL FOR A PARTICULAR SERIES OR A NOTICE OF
GUARANTEED DELIVERY MAY BE USED TO TENDER SHARES OF SUCH SERIES.
 
  The Adjustable Rate Preferred is listed and traded on the New York Stock
Exchange under the symbol "PSDprB." There is no established trading market for
the other two Series of Preferred. The last reported sale price on the New
York Stock Exchange, as of the close of business on July 10, 1997, for the
Adjustable Rate Preferred is shown on the front cover of this Offer to
Purchase. Shareholders are urged to obtain a current market quotation, if
available, for their Shares.
 
  The August 1997 Dividend for each Series of Preferred has been declared and
will be paid on August 15, 1997 to holders of record as of the close of
business on July 21, 1997. A tender of Shares pursuant to the Offer will not
deprive any shareholder of his or her right to receive the August 1997
Dividend, regardless of when such tender is made. Holders of Shares tendered
into and purchased pursuant to the Offer will not be entitled to any dividends
in respect of any later dividend periods (or any portion thereof). See "Price
Range of Shares; Dividends."
 
  Tendering shareholders will not be obligated to pay brokerage commissions,
solicitation fees or, subject to the Instructions to the Letter of
Transmittal, stock transfer taxes on the purchase of Shares by PSE. PSE will
pay all charges and expenses of Smith Barney Inc. (the "Dealer Manager"),
ChaseMellon Shareholder Services, L.L.C. (the "Depositary") and MacKenzie
Partners, Inc. (the "Information Agent") incurred in connection with the
Offer. In addition, PSE will pay to the Soliciting Dealer, if any, designated
by the holder tendering Shares, the solicitation fee described on the front
cover of this Offer to Purchase. See "Fees and Expenses." ANY TENDERING
SHAREHOLDER OR OTHER PAYEE WHO FAILS TO COMPLETE AND SIGN THE SUBSTITUTE FORM
W-9 THAT IS INCLUDED IN THE LETTER OF TRANSMITTAL MAY BE SUBJECT TO A REQUIRED
FEDERAL INCOME TAX BACKUP WITHHOLDING OF 31% OF THE GROSS PROCEEDS PAYABLE TO
SUCH SHAREHOLDER OR OTHER PAYEE PURSUANT TO THE OFFER. See "Terms of the
Offer--Procedure for Tendering Shares" and "Special Factors--Certain Federal
Income Tax Consequences."
 
  Shareholders are not under any obligation to tender Shares pursuant to the
Offer. The Offer does not constitute notice of redemption of any Series of
Preferred pursuant to PSE's Restated Articles of Incorporation, as amended
(the "Restated Articles") nor does PSE intend to effect any such redemption by
making the Offer. The Offer does not constitute a waiver by PSE of any option
it has to redeem Shares. See "Special Factors--Purpose of the Offer; Certain
Effects of the Offer."
 
                                       7

  Copies of this Offer to Purchase and an applicable Letter of Transmittal are
being mailed to record holders of Shares and will be furnished to brokers,
banks and similar persons whose names, or the names of whose nominees, appear
on PSE's shareholder list or, if applicable, who are listed as participants in
a clearing agency's security position listing for subsequent transmittal to
beneficial owners of the Shares.
 
                                SPECIAL FACTORS
 
PURPOSE OF THE OFFER; CERTAIN EFFECTS OF THE OFFER
 
  As described under "Source and Amount of Funds," PSE intends to purchase the
Shares with funds from the issuance of short-term debt. On June 6, 1997, PSE
sold $100 million of junior subordinated debentures to a subsidiary trust of
PSE, which trust, in order to fund the purchase of such debentures, issued
$100 million of PSE obligated, mandatorily redeemable preferred securities in
a private placement. The proceeds from the sale of the junior subordinated
debentures were used to reduce short-term debt. PSE believes that it would be
economically attractive to PSE to purchase the Shares because interest
payments on the junior subordinated debentures, unlike dividends paid on
preferred stock, are deductible by PSE for federal income tax purposes.
 
  The Offer was authorized by the unanimous vote of PSE's Board of Directors.
No approval of the holders of any Shares or the holders of any of PSE's other
securities is required in connection with the Offer. No appraisal rights are
available to holders of Shares in connection with the Offer.
 
  PSE believes the Offer is fair to unaffiliated holders of Shares. In making
this determination on July 10, 1997, PSE considered that (a) the Offer would
give holders of the Adjustable Rate Preferred the opportunity to sell their
Shares at what PSE believed to be a premium over the expected price at which
such Shares would trade in the market on such date and that the Offer provides
such holders who are considering a sale of all or a portion of the Shares of
Adjustable Rate Preferred the opportunity to sell those Shares for cash
without the usual transaction costs associated with open-market sales and (b)
the Offer would give holders of the other two Series of Preferred an
opportunity to sell Shares for which there is no established trading market.
See "Price Range of Shares; Dividends." PSE did not find it practicable to,
and did not, quantify or otherwise assign relative weights to these factors.
PSE does not believe that the transactions will result in a material change to
PSE's net book value, going concern value or future prospects, and,
accordingly, PSE did not take these factors into account in assessing the
fairness of the Offer to unaffiliated holders of Shares. Trading of the Shares
has been limited and sporadic. Therefore, PSE determined the Offer price for
each Series of Preferred with reference to certain objective factors,
including, but not limited to, yields on U.S. Treasury and municipal
securities, yields on comparable preferred securities, the prior trading
characteristics of each Series of Preferred, as well as certain subjective
factors, including, but not limited to, general industry outlook, general
market supply of securities of similar type and supply and demand factors in
the securities markets generally. Although the weighting of these factors is a
subjective determination, PSE gave relatively more weight to objective
factors, such as yields on U.S. Treasury and municipal securities and yields
on comparable preferred securities.
 
  Neither PSE nor its Board of Directors received any report, opinion or
appraisal from an outside party related to the Offer, including, but not
limited to, any report, opinion or appraisal relating to the consideration or
the fairness of the consideration to be offered to the holders of the Shares
or the fairness of such Offer to PSE or the unaffiliated holders of Shares.
Neither the Board of Directors nor any director individually has retained an
unaffiliated representative to act solely on behalf of unaffiliated holders of
Shares for the purposes of negotiating the terms of the Offer or preparing a
report concerning the fairness of the Offer. Neither PSE nor its Board of
Directors believed these measures were necessary to ensure fairness in light
of the fact that the Offer will not result in a liquidation or change in
control of PSE.
 
  After the consummation of the Offer, PSE reserves the right to purchase
additional Shares on the open market, in privately negotiated transactions,
through one or more tender offers or otherwise. Any such purchases may be on
the same terms as, or on terms which are more or less favorable to holders of
Shares than, the terms of the Offer. However, Rule 13e-4(f)(6) under the
Exchange Act prohibits PSE and its affiliates from purchasing any Shares of a
Series of Preferred, other than pursuant to the Offer, until at least ten
business days after the
 
                                       8
<PAGE>
 
Expiration Time with respect to that Series of Preferred. Any future purchases
of Shares by PSE would depend on many factors, including the market price of
the Shares, PSE's business and financial position, restrictions on PSE's
ability to purchase Shares imposed by law or by New York Stock Exchange
listing requirements and general economic and market conditions.
 
  Shareholders are not under any obligation to tender Shares pursuant to the
Offer. In accordance with its Restated Articles, PSE is required to redeem
3,000 Shares of its 4.70% Preferred Stock ($100 par value) (the "4.70%
Preferred") and 3,000 Shares of its 4.84% Preferred Stock ($100 par value)
(the "4.84% Preferred") on May 15 of each year at a redemption price in each
case of $100 per Share plus accrued dividends. In addition, each Series of
Preferred is redeemable at the option of PSE at the following redemption
prices: the Adjustable Rate Preferred at $27.50 per share if redeemed on or
prior to February 1, 1999 and at $25 per share if redeemed thereafter; the
4.70% Preferred at $101 per share; and the 4.84% Preferred at $102 per share,
in each case plus accrued dividends. The Offer does not constitute notice of
redemption of any Series of Preferred pursuant to PSE's Restated Articles, nor
does PSE intend to effect any such redemption by making the Offer. The Offer
does not constitute a waiver by PSE of any option it has to redeem Shares.
 
  Each Series of Preferred ranks equally with the other Series of Preferred
with respect to priority in payment of dividends and in distribution of
capital assets upon dissolution, liquidation or winding up of PSE
("Liquidation"). Before any distribution may be made to the holders of PSE's
common stock or preference stock upon any Liquidation: (a) the holders of the
Adjustable Rate Preferred will be entitled to receive, upon any voluntary
Liquidation on or prior to February 1, 1999, $27.50 per Share, or upon any
other Liquidation, $25 per Share, and (b) the holders of the other Series of
Preferred will be entitled to receive, upon any Liquidation, $100 per share,
in each case plus accrued dividends. PSE's Articles of Incorporation provide
that the sale, conveyance, exchange or transfer of all or substantially all of
PSE's property, or the consolidation of PSE with, or merger of PSE into, any
other entity will not be deemed a Liquidation.
 
  Shares that PSE purchases pursuant to the Offer will be retired and
canceled, which will reduce the number of Shares that might otherwise trade
publicly and will reduce the number of holders of Shares. This could adversely
affect the liquidity and market value of the Shares not purchased in the
Offer. Depending upon the number of Shares of Adjustable Rate Preferred
purchased pursuant to the Offer, the Adjustable Rate Preferred may no longer
meet the NYSE's requirements for continued listing. According to the NYSE's
published guidelines, the NYSE would consider delisting the Adjustable Rate
Preferred if, among other things, the number of publicly-held Shares of
Adjustable Rate Preferred should fall below 100,000 or the aggregate market
value of such Shares should fall below $2,000,000. If, as a result of the
purchase of Shares pursuant to the Offer or otherwise, the Adjustable Rate
Preferred no longer meets the NYSE's requirements for continued listing and
the listing of such Shares is discontinued, the market for the Adjustable Rate
Preferred would be adversely affected.
 
  In the event of the delisting of the Adjustable Rate Preferred, it is
possible that such Shares would continue to trade on another securities
exchange or in the over-the-counter market and that price quotations would be
reported by such exchange, by the National Association of Securities Dealers,
Inc. through the National Association of Securities Dealers Automated
Quotation System ("Nasdaq") or by other sources. The extent of the public
market for the Adjustable Rate Preferred and the availability of such
quotations, however, would depend upon such factors as the number of
shareholders remaining at such time, the interest in maintaining a market in
the Adjustable Rate Preferred on the part of securities firms, the possible
termination of registration under the Exchange Act as described below and
other factors.
 
  The Adjustable Rate Preferred is currently registered under Section 12(b) of
the Exchange Act, and PSE's Preferred Stock, as a class, is registered under
Section 12(g) of the Exchange Act. Registration of any securities under the
Exchange Act may be terminated upon application of PSE to the Securities and
Exchange Commission (the "Commission") pursuant to Section 12(g)(4) of the
Exchange Act if such securities are neither held by 300 or more holders of
record nor listed on a national securities exchange. Termination of
registration of PSE's Preferred Stock under the Exchange Act would reduce
substantially the information required to be furnished by PSE to holders of
PSE's Preferred Stock (although PSE would, among other things, remain subject
to the
 
                                       9
<PAGE>
 
reporting obligations under the Exchange Act as a result of its other
outstanding securities) and would make certain provisions of the Exchange Act,
such as the requirement of Rule 13e-3 thereunder with respect to "going
private" transactions, no longer applicable in respect of PSE's Preferred
Stock. If registration of any Series of Preferred under the Exchange Act were
terminated, Shares of such Series of Preferred would no longer be eligible for
Nasdaq reporting.
 
  Except as set forth herein, PSE has no plans or proposals which relate to or
would result in (a) the acquisition by any person of additional securities of
PSE or the disposition of securities of PSE; (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving PSE or
any of its subsidiaries; (c) a sale or transfer of a material amount of assets
of PSE or any of its subsidiaries; (d) any change in the present Board of
Directors or management of PSE; (e) any material change in the present
dividend rate or policy, or indebtedness or capitalization of PSE; (f) any
other material change in PSE's corporate structure or business; (g) any change
in PSE's Restated Articles or Bylaws or any actions which may impede the
acquisition of control of PSE by any person; (h) a class of equity securities
of PSE being delisted from a national securities exchange; (i) a class of
equity securities of PSE becoming eligible for termination of registration
pursuant to Section 12(g)(4) of the Exchange Act; or (j) the suspension of
PSE's obligation to file reports pursuant to Section 15(d) of the Exchange
Act.
 
  NEITHER PSE, ITS BOARD OF DIRECTORS NOR ANY OF ITS OFFICERS MAKES ANY
RECOMMENDATION TO ANY SHAREHOLDER AS TO WHETHER TO TENDER ALL OR ANY SHARES.
EACH SHAREHOLDER MUST MAKE HIS OR HER OWN DECISION WHETHER TO TENDER SHARES
AND, IF SO, HOW MANY SHARES TO TENDER.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  In General. The following summary describes certain United States federal
income tax consequences relating to the Offer. The summary deals only with
Shares held as capital assets within the meaning of the Internal Revenue Code
of 1986, as amended (the "Code"), and does not address tax consequences that
may be important to investors in special tax situations, such as certain
financial institutions, tax-exempt organizations, life insurance companies,
dealers in securities or currencies, or shareholders holding the Shares as
part of a conversion transaction, as part of a hedging transaction, or as a
position in a straddle for tax purposes. Each shareholder should consult a tax
advisor with regard to the Offer and the application of United States federal
income tax laws, as well as the laws of any state, local or foreign taxing
jurisdiction.
 
  Characterization of the Sale. A sale of Shares pursuant to the Offer will be
a taxable transaction for United States federal income tax purposes and will
be treated as a "sale or exchange," rather than as a distribution by PSE with
respect to the Shares, if under Section 302 of the Code the sale (i) results
in a "complete redemption" of all the stock in PSE owned by the shareholder or
(ii) is "not essentially equivalent to a dividend" with respect to the
shareholder. The receipt of cash by a shareholder will constitute a "complete
redemption" if all of the PSE stock actually owned by the shareholder and
constructively owned by the shareholder under the attribution rules described
below is sold pursuant to the Offer. The receipt of cash will be "not
essentially equivalent to a dividend" if the sale of Shares results in a
"meaningful reduction" in the shareholder's interest in PSE stock.
Contemporaneous dispositions or acquisitions of PSE stock may be deemed to be
part of an integrated transaction which will be taken into account in this
connection.
 
  In applying the foregoing rules, there will be taken into account not only
stock actually owned by the shareholder, but also stock constructively owned
under the attribution rules of Section 318 of the Code. Under Section 318, a
shareholder may constructively own stock actually owned, and in some cases
constructively owned, by certain related individuals or entities and stock
which the shareholder has the right to acquire by exercise of an option or
conversion right.
 
                                      10
<PAGE>
 
  If under Section 302 a sale of the Shares is treated as a "sale or
exchange," the tendering shareholder will recognize gain or loss equal to the
difference between the amount of cash received and the shareholder's tax basis
in the Shares sold. Any such gain or loss will be capital gain or loss, and
will be long-term capital gain or loss if the Shares have been held for more
than one year. If the sale is not so treated as a "sale or exchange," the
tendering shareholder will be deemed to have received a dividend in the amount
of the cash received to the extent of the shareholder's allocable portion of
PSE's earnings and profits as determined for federal income tax purposes. Any
such dividend would be includible in the gross income of the shareholder as
ordinary income in its entirety without reduction for the tax basis of the
Shares sold pursuant to the Offer. The shareholder's basis in the Shares sold
would be added to such shareholder's basis in any retained PSE stock. To the
extent that the amount of cash received exceeds the shareholder's allocable
portion of PSE's earnings and profits, the shareholder's basis will be reduced
by the amount of such excess. Any amount received in excess of the
shareholder's tax basis will be treated as received in exchange for the
shareholder's PSE stock.
 
  Corporate Shareholders. If a sale of Shares is treated as a dividend, a
corporate shareholder may be entitled to claim a dividends-received deduction
for a portion of the dividend, subject to applicable limitations. Corporate
shareholders should consider the effect of Section 246(c) of the Code, which
disallows the dividends-received deduction with respect to stock that is held
for 45 days or less. Both the House Ways and Means Committee and the Senate
Finance Committee, in connection with the consideration of the pending Revenue
Reconciliation Act of 1997, have proposed to apply this rule each time a
dividend is declared. For this purpose, the length of time a
shareholder is deemed to have held stock may be reduced by periods during
which the shareholder's risk of loss with respect to the stock is diminished
by reason of the existence of certain options or other transactions. Also, if
a corporate shareholder has incurred indebtedness directly attributable to an
investment in stock, the dividends-received deduction may be reduced.
 
  Any amount received by a corporate shareholder pursuant to the Offer that is
treated as a dividend would be likely to constitute an "extraordinary
dividend" under Section 1059 of the Code. For this purpose, all dividends
received by a shareholder within, and having their ex-dividend dates within,
an 85-day period (expanded to a 365-day period in the case of dividends
received in such period that in the aggregate exceed 20% of the shareholder's
adjusted tax basis in the stock) are aggregated and also treated as
extraordinary dividends. Under Section 1059 of the Code a corporate
shareholder is required to reduce its basis (but not below zero) in its stock
by the non-taxed portion of the dividend (i.e., the portion of the dividend
for which a deduction is allowed). If such portion exceeds the shareholder's
tax basis in its Shares (and its tax basis in any other stock of PSE that it
owns), the shareholder would be required to treat the excess as gain from the
sale of its remaining Shares or other PSE stock. Corporate shareholders should
consult their own tax advisors as to the application of Section 1059 of the
Code to the Offer. Under a legislative proposal by both the House Ways and
Means Committee and the Senate Finance Committee in connection with the
consideration of the pending Revenue Reconciliation Act of 1997, Section 1059
would be amended to provide for immediate recognition of gain in certain
circumstances where the non-taxed portion of the dividend exceeds the basis of
the shares surrendered.
 
  Foreign Shareholders. PSE will withhold United States federal income tax at
a rate of 30% from gross proceeds paid pursuant to the Offer to foreign
shareholders, unless PSE determines that a reduced rate of withholding is
applicable pursuant to a tax treaty or that an exemption from withholding is
applicable because such gross proceeds are effectively connected with the
conduct of a trade or business by the foreign shareholder within the United
States. In order to claim an exemption from withholding on the ground that
gross proceeds paid pursuant to the Offer are effectively connected with the
conduct of a trade or business by a foreign shareholder within the United
States, the shareholder must deliver to the Depositary a properly executed
Internal Revenue Service Form 4224. A foreign shareholder may be eligible to
file for a refund of such tax or a portion of such tax if such shareholder (i)
meets the "complete redemption" or "not essentially equivalent to a dividend"
tests described above, (ii) is entitled to a reduced rate of withholding
pursuant to a treaty and PSE withheld at a higher rate, or (iii) is otherwise
able to establish that no tax or a reduced amount of tax was due.
 
  Backup Withholding. See "Terms of the Offer--Procedure for Tendering Shares"
with respect to the application of backup withholding tax.

  Legislative Proposals. Congress is currently considering the proposed
Revenue Reconciliation Act of 1997. Investors are encouraged to consult with
their tax advisors regarding the possible effects of the provisions of such
proposed legislation discussed herein and other provisions contained therein.
 
  THE TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY.
THE TAX CONSEQUENCES OF A SALE PURSUANT TO THE OFFER MAY VARY DEPENDING UPON,
AMONG OTHER THINGS, THE PARTICULAR CIRCUMSTANCES OF THE TENDERING SHAREHOLDER.
NO INFORMATION IS PROVIDED HEREIN AS TO THE STATE, LOCAL OR FOREIGN TAX
CONSEQUENCES OF THE OFFER. SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS TO DETERMINE THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES OF SALES PURSUANT TO THE OFFER.
 
                              TERMS OF THE OFFER
 
NUMBER OF SHARES; PURCHASE PRICE; EXPIRATION TIME; RECEIPT OF DIVIDEND
 
  Upon the terms and subject to the conditions described herein and in the
applicable Letter of Transmittal, PSE will purchase any and all Shares that
are validly tendered on or prior to the applicable Expiration Time (and not
properly withdrawn in accordance with "Terms of the Offer--Withdrawal Rights")
at the purchase price per share listed on the front cover of this Offer to
Purchase which is applicable to the Shares tendered, net to the seller in
cash. See "Terms of the Offer--Extension; Termination; Amendments" and "--
Certain Conditions of the Offer."
 
  The later of 8:00 P.M., New York City time, on August 8, 1997, or the latest
time and date to which the Offer is extended with respect to any Series of
Preferred, is referred to herein as the "Expiration Time." There can be no
assurance that PSE will exercise its right to extend the Offer with respect to
any Series of Preferred.
 
  Each Offer for a Series of Preferred is independent of the Offer for any
other Series of Preferred.
 
  The August 1997 Dividend for each Series of Preferred has been declared and
will be paid on August 15, 1997 to holders of record as of the close of
business on July 21, 1997. A tender of Shares pursuant to the Offer will not
deprive any shareholder of his or her right to receive the August 1997
Dividend, regardless of when such tender is made. Holders of Shares tendered
into and purchased pursuant to the Offer will not be entitled to any dividends
in respect of any later dividend periods (or any portion thereof).
 
  No alternative, conditional or contingent tenders will be accepted.
 
PROCEDURE FOR TENDERING SHARES
 
  To tender Shares validly pursuant to the Offer, the tendering holder of
  Shares must either:
 
    (a) send to the Depositary (at one of its addresses set forth on the back
  cover of this Offer to Purchase) a properly completed and duly executed
  Letter of Transmittal for the Series of Preferred tendered or facsimile
  thereof, together with any required signature guarantees and any other
  documents required by the Letter of Transmittal, and either (i) cause
  certificates for the Shares to be tendered to be received by the
  Depositary, at one of such addresses or (ii) cause such Shares to be
  delivered pursuant to the procedures for book-entry transfer described
  below (and a confirmation of such delivery received by the Depositary), in
  each case on or prior to the applicable Expiration Time; or
 
    (b) comply with the guaranteed delivery procedure described under
  "Guaranteed Delivery Procedure" below.
 
                                      12
<PAGE>
 
  The Depositary will establish an account with respect to each Series of
Preferred at The Depository Trust Company and Philadelphia Depositary Trust
Company (collectively referred to as the "Book-Entry Transfer Facilities") for
purposes of the Offer within two business days after the date of this Offer to
Purchase, and any financial institution that is a participant in the system of
any Book-Entry Transfer Facility may make delivery of Shares by causing such
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account in accordance with the procedures of such Book-Entry Transfer
Facility. Although delivery of Shares may be effected through book-entry
transfer, a properly completed and duly executed Letter of Transmittal for the
Series of Preferred tendered or facsimile thereof, together with any required
signature guarantees and any other required documents, must, in any case, be
received by the Depositary at one of its addresses set forth on the back cover
of this Offer to Purchase on or prior to the applicable Expiration Time, or
the tendering holder of Shares must comply with the guaranteed delivery
procedure described below.
 
  DELIVERY OF THE APPLICABLE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED
DOCUMENTS TO ONE OF THE BOOK-ENTRY TRANSFER FACILITIES DOES NOT CONSTITUTE
DELIVERY TO THE DEPOSITARY.
 
  Except as otherwise provided below, all signatures on a Letter of
Transmittal must be guaranteed by a firm that is a member of a registered
national securities exchange or the National Association of Securities
Dealers, Inc., or by a commercial bank or trust company having an office or
correspondent in the United States which is a participant in an approved
Signature Guarantee Medallion Program (each of the foregoing being referred to
as an "Eligible Institution"). Signatures on a Letter of Transmittal need not
be guaranteed if (a) the Letter of Transmittal is signed by the registered
holder of the Shares tendered therewith and such holder has not completed the
box entitled "Special Payment Instructions" or the box entitled "Special
Delivery Instructions" on the Letter of Transmittal or (b) such Shares are
tendered for the account of an Eligible Institution. See Instructions 2 and 5
of the Letter of Transmittal.
 
  Guaranteed Delivery Procedure. If a shareholder desires to tender Shares
pursuant to the Offer and cannot deliver certificates for such Shares and all
other required documents to the Depositary at or prior to the applicable
Expiration Time, or the procedure for book-entry transfer cannot be complied
with in a timely manner, such Shares may nevertheless be tendered if all of
the following conditions are met:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed Delivery
  in the form provided by PSE (with any required signature guarantees) is
  received by the Depositary as provided below at or prior to the applicable
  Expiration Time; and
 
    (iii) the certificates for such Shares (or a confirmation of a book-entry
  transfer of such Shares into the Depositary's account at one of the Book-
  Entry Transfer Facilities), together with a properly completed and duly
  executed Letter of Transmittal for the Series of Preferred to be tendered
  (or facsimile thereof) and any other documents required by the Letter of
  Transmittal, are received by the Depositary no later than 5:00 p.m., New
  York City time, on the third New York Stock Exchange trading day after the
  date of execution of the Notice of Guaranteed Delivery.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile transmittal or mail to the Depositary and must include a guarantee
by an Eligible Institution in the form set forth in such Notice.
 
  THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING SHAREHOLDER. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  TO AVOID FEDERAL INCOME TAX BACKUP WITHHOLDING EQUAL TO 31% OF THE GROSS
PAYMENTS MADE PURSUANT TO THE OFFER, EACH SHAREHOLDER MUST NOTIFY THE
DEPOSITARY OF SUCH SHAREHOLDER'S CORRECT TAXPAYER IDENTIFICATION
 
                                      13
<PAGE>
 
NUMBER AND PROVIDE CERTAIN OTHER INFORMATION BY PROPERLY COMPLETING THE
SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF TRANSMITTAL. FOREIGN
SHAREHOLDERS MUST SUBMIT A PROPERLY COMPLETED FORM W-8 IN ORDER TO AVOID THE
APPLICABLE BACKUP WITHHOLDING; PROVIDED, HOWEVER, THAT BACKUP WITHHOLDING WILL
NOT APPLY TO FOREIGN SHAREHOLDERS SUBJECT TO 30% (OR LOWER TREATY RATE)
WITHHOLDING ON GROSS PAYMENTS RECEIVED PURSUANT TO THE OFFER (AS DISCUSSED
UNDER "SPECIAL FACTORS--CERTAIN FEDERAL INCOME TAX CONSEQUENCES").
 
  EACH SHAREHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISOR.
 
  All questions as to the form of documents and the validity, eligibility
(including time of receipt) and acceptance for payment of any tender of Shares
will be determined by PSE, in its sole discretion, and its determination shall
be final and binding. PSE reserves the absolute right to reject any or all
tenders of Shares that (i) it determines are not in proper form or (ii) the
acceptance for payment of or payment for which may, in the opinion of PSE's
counsel, be unlawful. PSE also reserves the absolute right to waive any defect
or irregularity in any tender of Shares. None of PSE, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty
to give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice.
 
  PSE will, as provided in Instruction 10 of the applicable Letter of
Transmittal, pay the solicitation fee described on the front cover of this
Offer to Purchase for any Shares tendered and accepted for payment and paid
for pursuant to the Offer, which Shares are covered by a Letter of Transmittal
which designates, as having solicited and obtained the tender, the name of (i)
any broker or dealer in securities, including the Dealer Manager in its
capacity as a broker or dealer, who is a member of any national securities
exchange or of the National Association of Securities Dealers, Inc. (the
"NASD"), (ii) any foreign broker or dealer not eligible for membership in the
NASD which agrees to conform to the NASD's Rules of Fair Practice in
soliciting tenders outside the United States to the same extent as though it
were an NASD member, or (iii) any bank or trust company (each of which is
referred to herein as a "Soliciting Dealer"). No such fee shall be payable to
a Soliciting Dealer if such Soliciting Dealer is required for any reason to
transfer the amount of such fee to a depositing holder (other than itself). No
such fee shall be paid to a Soliciting Dealer with respect to Shares tendered
for such Soliciting Dealer's own account. No broker, dealer, bank, trust
company or fiduciary shall be deemed to be an agent of PSE, the Depositary,
the Information Agent or the Dealer Manager for the purposes of the Offer.
 
WITHDRAWAL RIGHTS
 
  Tenders of Shares of a Series of Preferred made pursuant to the Offer may be
withdrawn at any time prior to the Expiration Time with respect to such Series
of Preferred. Thereafter, such tenders are irrevocable, except that they may
be withdrawn after Thursday, September 4, 1997 unless theretofore accepted for
payment as provided in this Offer to Purchase. If, with respect to any Series
of Preferred, PSE extends the period of time during which the Offer is open,
is delayed in accepting for payment or paying for Shares of that Series of
Preferred or is unable to accept for payment or pay for Shares of that Series
of Preferred pursuant to the Offer for any reason, then, without prejudice to
PSE's rights under the Offer, the Depositary may, on behalf of PSE, retain all
Shares of that Series of Preferred tendered, and such Shares may not be
withdrawn except as otherwise provided in this "Terms of the Offer--Withdrawal
Rights," subject to Rule 13e-4(f)(5) under the Securities Exchange Act of 1934
(the "Exchange Act"), which provides that the issuer "making the tender offer
shall either pay the consideration offered, or return the tendered securities,
promptly after the termination or withdrawal of the tender offer."
 
  To be effective, a written or facsimile transmission notice of withdrawal
must be timely received by the Depositary at one of its addresses or facsimile
numbers set forth on the back cover of this Offer to Purchase and must specify
the name of the person who tendered the Shares to be withdrawn and the number
of Shares of each
 
                                      14
<PAGE>
 
Series of Preferred to be withdrawn. If the Shares to be withdrawn have been
delivered to the Depositary, a signed notice of withdrawal with signatures
guaranteed by an Eligible Institution (except in the case of Shares tendered
by an Eligible Institution) must be submitted prior to the release of such
Shares. In addition, such notice must specify, in the case of Shares tendered
by delivery of certificates, the name of the registered holder (if different
from that of the tendering shareholder) and the serial numbers shown on the
particular certificates evidencing the Shares to be withdrawn or, in the case
of Shares tendered by book-entry transfer, the name and number of the account
at one of the Book-Entry Transfer Facilities to be credited with the withdrawn
Shares and the name of the registered holder (if different from the name of
such account). Withdrawals may not be rescinded, and Shares withdrawn will
thereafter be deemed not validly tendered for purposes of the Offer. However,
withdrawn Shares may be retendered by again following one of the procedures
described in "Terms of the Offer--Procedure for Tendering Shares" at any time
prior to the applicable Expiration Time.
 
  All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by PSE in its sole discretion, and its
determination shall be final and binding. None of PSE, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty
to give notification of any defect or irregularity in any notice of withdrawal
or incur any liability for failure to give any such notification.
 
ACCEPTANCE FOR PAYMENT OF SHARES AND PAYMENT OF PURCHASE PRICE
 
  Upon the terms and subject to the conditions of the Offer and as promptly as
practicable after the Expiration Time with respect to a Series of Preferred,
PSE will accept for payment and pay for Shares of that Series of Preferred
validly tendered. See "Terms of the Offer--Number of Shares; Purchase Price;
Expiration Time; Receipt of Dividends," "--Extension; Termination;
Amendments," and "--Certain Conditions of the Offer" and "Source and Amount of
Funds." Payment for all Shares of that Series of Preferred validly tendered on
or prior to the applicable Expiration Time and accepted for payment pursuant
to the Offer will be made by the Depositary by check as promptly as
practicable. In all cases, payment for Shares accepted for payment pursuant to
the Offer will be made only after timely receipt by the Depositary of
certificates for Shares (or of a confirmation of a book-entry transfer of such
Shares into the Depositary's account at one of the Book-Entry Transfer
Facilities), a properly completed and duly executed Letter of Transmittal for
the Series of Preferred tendered or facsimile thereof, and any other required
documents.
 
  For purposes of the Offer, PSE will be deemed to have accepted for payment
(and thereby purchased) Shares that are validly tendered prior to the
applicable Expiration Time and not withdrawn as, if and when it gives oral or
written notice to the Depositary of its acceptance for payment of such Shares.
PSE will pay for Shares that it has purchased pursuant to the Offer by
depositing the purchase price therefor with the Depositary. The Depositary
will act as agent for tendering shareholders for the purpose of receiving
payment from PSE and transmitting payment to tendering shareholders. Under no
circumstances will interest be paid on amounts to be paid to tendering
shareholders, regardless of any delay in making such payment.
 
  Certificates for all Shares not purchased will be returned (or, in the case
of Shares tendered by book-entry transfer, such Shares will be credited to an
account maintained with a Book-Entry Transfer Facility) as promptly as
practicable, without expense to the tendering shareholder.
 
  Payment for Shares may be delayed in the event of difficulty in determining
the number of Shares properly tendered. In addition, if certain events occur,
PSE may not be obligated to purchase Shares pursuant to the Offer. See "Terms
of the Offer--Certain Conditions of the Offer."
 
  PSE will pay or cause to be paid any stock transfer taxes with respect to
the sale and transfer of any Shares to it or its order pursuant to the Offer.
If, however, payment of the purchase price is to be made to, or Shares not
tendered or not purchased are to be registered in the name of, any person
other than the registered holder, or if tendered Shares are registered in the
name of any person other than the person signing the Letter of Transmittal,
 
                                      15
<PAGE>
 
the amount of any stock transfer taxes (whether imposed on the registered
holder, such other person or otherwise) payable on account of the transfer to
such person will be deducted from the purchase price unless satisfactory
evidence of the payment of such taxes, or exemption therefrom, is submitted.
See Instruction 6 to the Letter of Transmittal.
 
CERTAIN CONDITIONS OF THE OFFER
 
  Notwithstanding any other provision of the Offer, PSE will not be required
to accept for payment or pay for any Shares of a Series of Preferred tendered,
and may terminate or amend the Offer with respect thereto, and may postpone
(subject to the requirements of the Exchange Act for prompt payment for or
return of Shares) the acceptance for payment of or payment for Shares of a
Series of Preferred tendered, if any of the following shall have occurred at
any time after the date of this Offer to Purchase and before payment for any
Shares of a Series of Preferred (whether or not such occurrence shall be
continuing at the time of such termination, amendment or postponement):
 
    (a) any action or proceeding shall have been threatened, instituted,
  pending or taken, or approval shall have been withheld, withdrawn or
  abrogated, or any statute, rule, regulation, judgment, order or injunction
  shall have been threatened, proposed, sought, promulgated, enacted,
  entered, amended, enforced or deemed to be applicable to the Offer or PSE,
  by any legislative body, court authority, agency or tribunal or any other
  person, including the Securities and Exchange Commission or the Washington
  Utilities and Transportation Commission (see "Source and Amount of Funds"),
  which, in PSE's sole judgment, would or might directly or indirectly (i)
  make the acceptance for payment of, or payment for, some or all of the
  Shares of that Series of Preferred illegal or challenge the acquisition of
  such Shares or otherwise relate to or affect the Offer in any manner, (ii)
  materially impair the contemplated benefits of the Offer to PSE or (iii)
  materially affect the business, condition (financial or other), income,
  operations or prospects of PSE, or otherwise materially impair in any way
  the contemplated future conduct of the business of PSE;
 
    (b) it shall have been publicly disclosed or PSE shall have learned that
  any person or "group" (within the meaning of Section 13(d)(3) of the
  Exchange Act) has acquired or proposes to acquire beneficial ownership of
  more than 5% of the outstanding common stock of PSE whether through the
  acquisition of stock, the formation of a group, the grant of any option or
  right or otherwise;
 
    (c) there shall have occurred (i) any general suspension of trading in,
  or limitation on prices for, securities on any national securities exchange
  or in the over-the-counter market, (ii) any significant decline in the
  market price of the Shares of that Series of Preferred, (iii) any change in
  the general political, market, economic or financial condition in the
  United States or abroad that could have a material adverse effect on PSE's
  business, operations, prospects or ability to obtain financing generally or
  the trading in the Shares of that Series of Preferred or other equity
  securities of PSE, (iv) the declaration of a banking moratorium or any
  suspension of payments in respect of banks in the United States or any
  limitation on, or any event which, in PSE's sole judgment, might affect,
  the extension of credit by lending institutions in the United States, (v)
  the commencement of a war, armed hostilities or other international or
  national calamity directly or indirectly involving the United States or
  (vi) in the case of any of the foregoing existing at the time of the
  commencement of the Offer, in PSE's sole judgment, a material acceleration
  or worsening thereof;
 
    (d) a tender or exchange offer with respect to some or all of the Shares
  of that Series of Preferred or other equity securities of PSE, or a merger,
  acquisition or other business combination proposal for PSE, shall have been
  proposed, announced or made by another person;
 
    (e) there shall have occurred any event or events that have resulted, or
  may in the sole judgment of PSE result, in an actual or threatened change
  in the business, condition (financial or other), income, operations, stock
  ownership or prospects of PSE and its subsidiaries;
 
    (f) Moody's Investors Service, Inc. or Standard & Poor's Corporation
  shall have (i) downgraded or withdrawn the rating accorded any securities
  of PSE, or (ii) publicly announced that it has under surveillance or
  review, with possible negative implications, its rating of any securities
  of PSE; or
 
    (g) there shall have occurred any decline in the Standard & Poor's
  Composite 500 Stock Index by an amount in excess of 15% measured from the
  close of business on Thursday, July 10, 1997;
 
                                      16
<PAGE>
 
and, in the sole judgment of PSE, such event or events make it undesirable or
inadvisable to proceed with the Offer with respect to such Series of Preferred
or with such acceptance for payment or payment. The Offer for each Series of
Preferred is independent of the Offer for any other Series of Preferred. The
consummation of the Offer for any Series of Preferred is not conditioned on
the consummation of the Offer for all Series of Preferred or for any other
Series of Preferred.
 
  The foregoing conditions are for the sole benefit of PSE and may be asserted
by PSE regardless of the circumstances (including any action or inaction by
PSE) giving rise to any such condition, and any such condition may be waived
by PSE, in whole or in part, at any time and from time to time in its sole
discretion. The failure by PSE at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such right
shall be deemed an ongoing right which may be asserted at any time and from
time to time. Any determination by PSE concerning the events described above
will be final and binding on all parties.
 
EXTENSION; TERMINATION; AMENDMENTS
 
  Prior to the Expiration Time, PSE may, with respect to any Series of
Preferred, extend the period of time during which the Offer is open or
otherwise amend or modify the Offer and may terminate the Offer for any
reason. There can be no assurance, however, that PSE will extend the Offer.
During any such extension, all Shares of that Series of Preferred previously
tendered will remain subject to the Offer, except to the extent that such
Shares may be withdrawn as set forth in "Terms of the Offer--Withdrawal
Rights."
 
  After the Expiration Time, PSE may, with respect to each Series of
Preferred, upon the occurrence of any of the conditions specified in "Terms of
the Offer--Certain Conditions of the Offer," terminate the Offer and not
accept for payment or pay for any Shares tendered or, subject to Rule 13e-
4(f)(5) under the Exchange Act (which provides that the issuer "making the
tender offer shall either pay the consideration offered, or return the
tendered securities, promptly after the termination or withdrawal of the
tender offer"), postpone acceptance for payment of or payment for Shares.
 
  To effect any such extension, amendment, modification, termination or
postponement, PSE shall give oral or written notice to the Depositary and make
a public announcement thereof. Without limiting the manner in which PSE may
choose to make such a public announcement, PSE shall have no obligation
(except as otherwise required by applicable law) to publish, advertise or
otherwise communicate any such public announcement, other than by making a
release to the Dow Jones News Service, except in the case of an announcement
of an extension of the Offer with respect to any Series of Preferred, in which
case PSE shall have no obligation to publish, advertise or otherwise
communicate such announcement other than by issuing a notice of such extension
by press release or other public announcement, which notice shall be issued no
later than 9:00 a.m., New York City time, on the next business day after the
date of the previously scheduled Expiration Time with respect to that Series
of Preferred.
 
  If PSE materially changes the terms of the Offer or the information
concerning the Offer, or if it waives a material condition of the Offer, PSE
will extend the Offer to the extent required by Rules 13e-4(d)(2) and 13e-
4(e)(2) under the Exchange Act. Under these rules, the minimum period during
which an offer must remain open following material changes in the terms of the
offer or information concerning the offer (other than a change in price,
change in dealer's soliciting fee or change in percentage of securities
sought) will depend on the facts and circumstances, including the relative
materiality of such terms or information. In a published release, the
Commission has stated that, in its view, an offer should remain open for a
minimum of five business days from the date that a notice of such a material
change is first published, sent or given. The Offer with respect to any Series
of Preferred will be extended for at least ten business days from the time PSE
publishes, sends or gives to holders of Shares of that Series of Preferred a
notice that it will (a) increase or decrease the price it will pay for Shares
of that Series of Preferred or the amount of the dealer's soliciting fee or
(b) increase or decrease the percentage of Shares in that Series of Preferred
it seeks (except that the acceptance for payment of additional Shares of a
Series of Preferred not to exceed 2% of the outstanding Shares in that Series
of Preferred shall not be deemed to be an increase).

*  PSE's Board of Directors has declared a dividend on the Adjustable Rate
   Preferred equal to $0.368125 per Share to be paid on August 15, 1997 to
   holders of record at July 21, 1997.
 
  Dividends for the Adjustable Rate Preferred are payable when and as declared
by PSE's Board of Directors in an amount determined in accordance with a
formula described in PSE's Restated Articles. Dividends for the other Series
of Preferred are payable when and as declared by PSE's Board of Directors at
the rate per annum included in the title of the Series of Preferred listed on
the front cover of this Offer to Purchase. The August 1997 Dividend (which is
a regular quarterly dividend) for each Series of Preferred has been declared
and is to be paid on August 15, 1997 to holders of record as of the close of
business on July 21, 1997. A tender of Shares pursuant to the Offer will not
deprive any shareholder of his or her right to receive the August 1997
Dividend, regardless of when such tender is made. Holders of Shares tendered
into and purchased pursuant to the Offer will not be entitled to any dividends
in respect of any later dividend periods (or any portion thereof).
 
  As of July 7, 1997, there were approximately 457 holders of the Adjustable
Rate Preferred, 105 holders of the 4.70% Preferred and 191 holders of the
4.84% Preferred.

                          SOURCE AND AMOUNT OF FUNDS
 
  Assuming that PSE purchases all outstanding Shares pursuant to the Offer,
the total amount of funds required by PSE to purchase the Shares would be
approximately $45.4 million, excluding fees and other expenses. See "Fees and
Expenses." PSE intends to use the proceeds from the sale of its short-term
debt securities to fund the purchase of Shares pursuant to the Offer.
 
  On June 6, 1997, PSE sold $100 million of junior subordinated debentures to
a subsidiary trust of PSE, which trust, in order to fund the purchase of such
debentures, issued $100 million of PSE obligated, mandatorily redeemable
preferred securities of such trust in an unregistered private placement. PSE
applied the proceeds from the sale of its junior subordinated debentures to
reduce short-term debt.
 
               TRANSACTIONS AND AGREEMENTS CONCERNING THE SHARES
 
  In accordance with its Restated Articles, PSE is required to redeem 3,000
Shares of the 4.70% Preferred and 3,000 Shares of the 4.84% Preferred on May
15 of each year at a redemption price in each case of $100 per Share plus
accrued dividends. In addition to such mandatory redemptions, since January 1,
1995, PSE has purchased Shares as indicated in the following table.

  Smith Barney Inc. will act as Dealer Manager for PSE in connection with the

(a) upon acceptance for payment of Shares of Adjustable Rate Preferred
pursuant to the Offer, a fee equal to $0.125 per Share of Adjustable Rate
Preferred and (b) upon acceptance for payment of Shares of 4.70% Preferred or
4.84% Preferred pursuant to the Offer, a fee equal to $0.50 per Share of 4.70%
Preferred or 4.84% Preferred. The Dealer Manager will also be reimbursed by
PSE for its reasonable out-of-pocket expenses, including attorneys' fees, and
will be entitled to indemnification against certain liabilities, including
liabilities under the federal securities laws, or to contribution for payments
the Dealer Manager may be required to make in respect thereof. The Dealer
Manager has rendered, is currently rendering and is expected to continue to
render various investment banking and other advisory services to PSE. The
Dealer Manager has received, and will continue to receive, customary
compensation from PSE for such services.
 
  PSE will, as provided in Instruction 10 of the applicable Letter of
Transmittal, pay to a Soliciting Dealer (as defined below) a solicitation fee
of $0.50 per Share of Adjustable Rate Preferred and $1.50 per Share of the
other two Series of Preferred (except that for transactions for beneficial
owners equal to or exceeding 10,000 Shares of the Adjustable Rate Preferred or
2,500 Shares of either of the other two Series of Preferred, PSE will pay a
solicitation fee of $0.25 per Share of Adjustable Rate Preferred and $1.00 per
Share of the other two Series of Preferred, provided that such fee will be
paid 80% to the Dealer Manager and 20% to the Soliciting Dealer) for Shares
tendered and accepted for payment and paid for pursuant to the Offer, which
Shares are covered by a Letter of Transmittal which designates, as having
solicited and obtained the tender, the name of (i) any broker or dealer in
securities, including the Dealer Manager in its capacity as a broker or
dealer, who is a member of any national securities exchange or of the National
Association of Securities Dealers, Inc. (the "NASD"), (ii) any foreign broker
or dealer not eligible for membership in the NASD which agrees to conform to
the NASD's Rules of Fair Practice in soliciting tenders outside the United
States to the same extent as though it were an NASD member, or (iii) any bank
or trust company (each of which is referred to herein as a "Soliciting
Dealer"). No such fee shall be payable to a Soliciting Dealer if such
Soliciting Dealer is required for any reason to transfer the amount of such
fee to a depositing holder (other than itself). No such fee shall be payable
to a Soliciting Dealer with respect to Shares tendered for such Soliciting
Dealer's own account. No broker, dealer, bank, trust company or fiduciary
shall be deemed to be an agent of PSE, the Depositary, the Information Agent
or the Dealer Manager for the purposes of the Offer.
 
  PSE has retained ChaseMellon Shareholder Services, L.L.C. as Depositary and
MacKenzie Partners, Inc. as Information Agent in connection with the Offer.
The Information Agent may contact shareholders by mail, telephone, telex,
telegraph and personal interviews, and may request brokers, dealers and other
nominee shareholders to forward materials relating to the Offer to beneficial
owners. The Depositary and the Information Agent will receive reasonable and
customary compensation for their services and will also be reimbursed for
certain out-of-pocket expenses. PSE has agreed to indemnify the Depositary and
the Information Agent against certain liabilities, including certain
liabilities under the federal securities laws, in connection with the Offer.
Neither the Information Agent nor the Depositary has been retained to make
solicitations or recommendations in connection with the Offer.
 
  Other than as described above, PSE will not pay any solicitation fees to any
broker, dealer, bank, trust company or other person for any Shares purchased
in connection with the Offer. PSE will reimburse such persons for customary
handling and mailing expenses incurred in connection with the Offer.
 
  PSE will pay all stock transfer taxes, if any, payable on account of the
acquisition of the Shares by PSE pursuant to the Offer, except in certain
circumstances where special payment or delivery procedures are utilized
pursuant to Instruction 6 of the Letter of Transmittal.

Association of Securities Dealers, Inc., or by a commercial bank or trust
company having an office or correspondent in the United States which is a
participant in an approved Signature Guarantee Medallion Program (an "Eligible
Institution"). Signatures on this Letter of Transmittal need not be guaranteed
(a) if this Letter of Transmittal is signed by the registered holder(s) of the
Shares (which term, for purposes of this document, shall include any
participant in one of the Book-Entry Transfer Facilities whose name appears on

holder(s) has not completed the box entitled "Special Payment Instructions" or
the box entitled "Special Delivery Instructions" on this Letter of Transmittal
or (b) if such Shares are tendered for the account of an Eligible Institution.
See Instruction 5.
 
  2. DELIVERY OF LETTER OF TRANSMITTAL AND SHARES. This Letter of Transmittal
is to be used either if certificates are to be forwarded herewith or if
delivery of Shares is to be made by book-entry transfer pursuant to the
procedures set forth under "Terms of the Offer--Procedure for Tendering
Shares" in the Offer to Purchase. Certificates for all physically delivered
Shares, or a confirmation of a book-entry transfer into the Depositary's
account at one of the Book-Entry Transfer Facilities of all Shares delivered
electronically, as well as a properly completed and duly executed Letter of
Transmittal (or facsimile thereof) and any other documents required by this
Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth on the front page of this Letter of Transmittal on or
prior to the Expiration Date (as defined in the Offer to Purchase) with
respect to a Series of Preferred. Shareholders who wish to tender but cannot
deliver their Shares and all other required documents to the Depositary on or
prior to the applicable Expiration Date must tender their Shares pursuant to
the guaranteed delivery procedure set forth under "Terms of the Offer--
Procedure for Tendering Shares" in the Offer to Purchase. Pursuant to such
procedure: (a) such tender must be made by or through an Eligible Institution,

"Terms of the Offer--Number of Shares; Purchase Price; Expiration Date;
Receipt of Dividend" in the Offer to Purchase. By executing this Letter of
Transmittal (or facsimile thereof), the tendering shareholder waives any right
to receive any notice of the acceptance for payment of the Shares.

that are to be tendered in the box entitled "Number of Shares Tendered." In

  5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written
on the face of the certificates without alteration, enlargement or any change
whatsoever.
 
  If any of the Shares tendered hereby is held of record by two or more
persons, all such persons must sign this Letter of Transmittal.

different certificates, it will be necessary to complete, sign and submit as
many separate Letters of Transmittal as there are different registrations of
certificates.
 
  If this Letter of Transmittal is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock
powers are required unless payment of the purchase price is to be made to, or
Shares not tendered or not purchased are to be registered in the name of, any
person other than the registered holder(s). Signatures on any such
certificates or stock powers must be guaranteed by an Eligible Institution.
See Instruction 1.
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear(s) on the
certificates for such Shares. Signature(s) on any such certificates or stock
powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
  If this Letter of Transmittal or any certificate or stock power is signed by

corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory
to PSE of the authority of such person so to act must be submitted.
 
  6. STOCK TRANSFER TAXES. PSE will pay or cause to be paid any stock transfer
taxes with respect to the sale and transfer of any Shares to it or its order
pursuant to the Offer. If, however, payment of the purchase price is to be
made to, or Shares not tendered or not purchased are to be registered in the
name of, any person other than the registered holder(s), or if tendered Shares
are registered in the name of any person other than the person(s) signing this
Letter of Transmittal, the amount of any stock transfer taxes (whether imposed
on the registered holder(s), such other person or otherwise) payable on
account of the transfer to such person will be deducted from the purchase
price unless satisfactory evidence of the payment of such taxes, or exemption
therefrom, is submitted. See "Terms of the Offer--Acceptance for Payment of
Shares and Payment of Purchase Price" in the Offer to Purchase. EXCEPT AS
PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY TO AFFIX TRANSFER TAX
STAMPS TO THE CERTIFICATES REPRESENTING SHARES TENDERED HEREBY.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If the check for the purchase
price of any Shares purchased is to be issued in the name of, and/or any
Shares not tendered or not purchased are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or
any certificate for Shares not tendered or not purchased are to be mailed to
someone other than the person(s) signing this Letter of Transmittal or to an
address other than that shown above in the box captioned "Description of
Shares Tendered," then the boxes captioned "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed. Shareholders tendering Shares by book-entry transfer will have any
Shares not accepted for payment returned by crediting the account maintained
by such shareholder at the Book-Entry Transfer Facility from which such
transfer was made.
 
  8. SUBSTITUTE FORM W-9 AND FORM W-8. The tendering shareholder is required
to provide the Depositary with either a correct Taxpayer Identification Number
("TIN") on Substitute Form W-9, which is provided under "Important Tax
Information" below, or a properly completed Form W-8. Failure to provide the
information on either Substitute Form W-9 or Form W-8 may subject the
tendering shareholder to 31% federal income tax backup withholding on the
payment of the purchase price. The box in Part 2 of Substitute Form W-9 may be
checked if the tendering shareholder has not been issued a TIN and has applied
for a number or intends to apply for a number in the near future. If the box
in Part 2 is checked and the Depositary is not provided with a TIN by the time
of payment, the Depositary will withhold 31% on all payments of the purchase
price thereafter until a TIN is provided to the Depositary.

Dealer Manager and such copies will be furnished promptly at PSE's expense.
Shareholders may also contact their local broker, dealer, commercial bank or
trust company for assistance concerning the Offer.
 
  10. SOLICITED TENDERS. PSE will pay a solicitation fee of $0.50 per Share of
Adjustable Rate Cumulative Preferred Stock, Series B ($25 par value) (except
that for transactions for beneficial owners equal to or exceeding 10,000
Shares, PSE will pay a solicitation fee of $0.25 per Share, provided that such
fee will be paid 80% to the Dealer Manager and 20% to the Soliciting Dealer)
for any Shares tendered, accepted for payment and paid pursuant to the Offer,
which Shares are covered by the Letter of Transmittal which designates, in the
box captioned "Solicited Tenders," as having solicited and obtained the
tender, the name of (i) any broker or dealer in securities, including the
Dealer Manager in its capacity as a dealer or broker, which is a member of any
national securities exchange or of the National Association of Securities
Dealers, Inc. (the "NASD"), (ii) any foreign broker or dealer not eligible for
membership in the NASD which agrees to conform to the NASD's Rules of Fair
Practice in soliciting tenders outside the United States to the same extent as
though it were an NASD member, or (iii) any bank or trust company (each of
which is referred to herein as a "Soliciting Dealer"). No such fee shall be
payable to a Soliciting Dealer with respect to the tender of Shares by a
holder unless the Letter of Transmittal accompanying such tender designates
such Soliciting Dealer. No such fee shall be payable to a Soliciting Dealer in
respect of Shares registered in the name of such Soliciting Dealer unless such
Shares are held by such Soliciting Dealer as nominee and such Shares are being
tendered for the benefit of one or more beneficial owners identified on the
Letter of Transmittal or on the Notice of Solicited Tenders (included in the
materials provided to brokers and dealers). No such fee shall be payable to a
Soliciting Dealer with respect to the tender of Shares by the holder of
record, for the benefit of the beneficial owner, unless the beneficial owner
has designated such Soliciting Dealer. If tendered Shares are being delivered
by book-entry transfer, the Soliciting Dealer must return a Notice of
Solicited Tenders to the Depositary within three business days after
expiration of the Offer to receive a solicitation fee. No such fee shall be
payable to a Soliciting Dealer if such Soliciting Dealer is required for any
reason to transfer the amount of such fee to a depositing holder (other than
itself). No such fee shall be paid to a Soliciting Dealer with respect to
Shares tendered for such Soliciting Dealer's own account. No broker, dealer,
bank, trust company or fiduciary shall be deemed to be the agent of PSE, the
Depositary, the Information Agent or the Dealer Manager for purposes of the
Offer.
 
  11. IRREGULARITIES. All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance of any tender
of Shares will be determined by PSE, in its sole discretion, and its
determination shall be final and binding. PSE reserves the absolute right to
reject any and all tenders of Shares that it determines are not in proper form
or the acceptance for payment of or payment for Shares that may, in the
opinion of PSE's counsel, be unlawful. PSE also reserves the absolute right to
waive any of the conditions to the Offer or any defect or irregularity in any
tender of Shares and PSE's interpretation of the terms and conditions of the
Offer (including these instructions) shall be final and binding. Unless
waived, any defects or irregularities in connection with tenders must be cured
within such time as PSE shall determine. None of PSE, the Dealer Manager, the
Depositary, the Information Agent or any other person shall be under any duty
to give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice. Tenders will not be
deemed to have been made until all defects and irregularities have been cured
or waived.
 
  12. LOST, DESTROYED OR STOLEN CERTIFICATES. If any certificate representing
Shares has been lost, destroyed or stolen, the shareholder should promptly
notify the Depositary by checking the box immediately following the special
payment/special delivery instructions and indicating the number of Shares
lost, destroyed or stolen. The shareholder will then be instructed as to the
procedures that must be taken in order to replace the certificate. The tender
of Shares pursuant to this Letter of Transmittal will not be valid unless
prior to the Expiration Date (as defined in the Offer to Purchase): (i) such
procedures have been completed and a replacement certificate for the Shares
has been delivered to the Depositary, or (ii) a Notice of Guaranteed Delivery
has been delivered to the Depositary. See Instruction 2.

                           IMPORTANT TAX INFORMATION
 
  Under federal income tax law, a shareholder whose tendered Shares are
accepted for payment is required to provide the Depositary (as payer) with
either such shareholder's correct TIN on Substitute Form W-9 below or a
properly completed Form W-8. If such shareholder is an individual, the TIN is
his or her Social Security number. For businesses and other entities, the
number is the employer identification number. If the Depositary is not
provided with the correct TIN or properly completed Form W-8, the shareholder
may be subject to a $50 penalty imposed by the Internal Revenue Service. In
addition, payments that are made to such shareholder with respect to Shares
purchased pursuant to the Offer may be subject to backup withholding. The Form
W-8 can be obtained from the Depositary. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
  If federal income tax backup withholding applies, the Depositary is required
to withhold 31% of any payments made to the shareholder. Backup withholding is
not an additional tax. Rather, the federal income tax liability of persons
subject to backup withholding will be reduced by the amount of the tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
  To avoid backup withholding on payments that are made to a shareholder with
respect to Shares purchased pursuant to the Offer, the shareholder is required
to notify the Depositary of his or her correct TIN by completing the
Substitute Form W-9 attached hereto certifying that the TIN provided on
Substitute Form W-9 is correct and that (1) the shareholder has not been
notified by the Internal Revenue Service that he or she is subject to federal
income tax backup withholding as a result of failure to report all interest or
dividends or (2) the Internal Revenue Service has notified the shareholder
that he or she is no longer subject to federal income tax backup withholding.
Foreign shareholders must submit a properly completed Form W-8 in order to
avoid the applicable backup withholding; provided, however, that backup
withholding will not apply to foreign shareholders subject to 30% (or lower
treaty rate) withholding on gross payments received pursuant to the Offer.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The shareholder is required to give the Depositary the social security
number or employer identification number of the registered owner of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.

per share listed above for the Series of Preferred tendered, net to the seller
in cash, upon the terms and subject to the conditions set forth in the Offer
to Purchase, dated July 11, 1997 (the "Offer to Purchase"), and in the Letter
of Transmittal for the Shares tendered. As to each Series of Preferred, the
Offer to Purchase, together with the applicable Letter of Transmittal,
constitutes the "Offer." PSE will purchase all Shares validly tendered and not
withdrawn, upon the terms and subject to the conditions of the Offer. See
"Terms of the Offer--Extension; Termination; Amendments" and "--Certain

  THE OFFER FOR EACH SERIES OF PREFERRED IS INDEPENDENT OF THE OFFERS FOR ANY
OTHER SERIES OF PREFERRED.
 
  We are asking you to contact your clients for whom you hold Shares
registered in your name (or in the name of your nominee) or who hold Shares
registered in their own names. Please bring the Offer to their attention as
promptly as possible.
 
  PSE will pay a solicitation fee of $0.50 per Share of Adjustable Rate
Preferred and $1.50 per Share of the other two Series of Preferred (except
that for transactions for beneficial owners equal to or exceeding 10,000
Shares of Adjustable Rate Preferred or 2,500 Shares of either of the other two
Series of Preferred, PSE will pay a solicitation fee of $0.25 per Share of
Adjustable Rate Preferred and $1.00 per Share of the other two Series of
Preferred, provided that such fee shall be paid 80% to the Dealer Manager and
20% to the Soliciting Dealer) for any Shares tendered, accepted for payment

(iii) any bank or trust company (each of which is referred to herein as a
"Soliciting Dealer"). No such fee shall be payable to a Soliciting Dealer with
respect to the tender of Shares by a holder unless the Letter of Transmittal
accompanying such tender designates such Soliciting Dealer. No such fee shall
be payable to a Soliciting Dealer is respect of Shares registered in the name
of such Soliciting Dealer unless such Shares are held by such Soliciting
Dealer as nominee and such Shares are being tendered for the benefit of one or
more beneficial owners identified on the Letter of Transmittal or on the

a Soliciting Dealer if such Soliciting Dealer is required for any reason to
transfer the amount of such fee to a depositing holder (other than itself). No
such fee shall be paid to a Soliciting Dealer with respect to Shares tendered
for such Soliciting Dealer's own account. No broker, dealer, bank, trust
company or fiduciary shall be deemed to be the agent of the PSE, the
Depositary (as defined below), the Dealer Manager or the Information Agent for

customary handling and mailing expenses incurred by them in forwarding
materials relating to the Offer to their customers. PSE will pay all stock
transfer taxes applicable to its purchase of Shares pursuant to the Offer,

Dear Shareholder:
 
  Puget Sound Energy, Inc. (formerly Puget Sound Power & Light Company) is
offering to purchase any and all shares of certain series of its preferred
stock. The offer gives shareholders the opportunity to sell their shares
without the usual transaction costs associated with a market sale. The
enclosed Offer to Purchase and the Letter of Transmittal are being provided to
help you understand the terms of Puget Sound Energy's offer. I encourage you
to read carefully these materials before making any decision with respect to
the offer.
 
  The front cover of the Offer to Purchase lists the various series of
preferred stock that Puget Sound Energy is offering to purchase and the
applicable purchase prices.
 
  All of the shares that are properly tendered (and are not withdrawn) will,
subject to the terms and conditions set forth in the Offer to Purchase and
Letter of Transmittal, be purchased at the applicable purchase price (net to
the selling shareholder). Shares that have been tendered and not purchased
will be returned to the shareholder.
 
  If you do not wish to sell your shares, you do not need to take any action.
 
  If you want to tender your shares, the instructions on how to do so are
explained in detail in the enclosed materials.
 
  Additional copies of the Offer to Purchase and related documents may be
obtained from MacKenzie Partners, Inc. at (800) 322-2885. Questions concerning
the offer should be directed to Smith Barney Inc. at (800) 655-4811.
 
  The August 1997 dividend for each series of preferred stock has been
declared and will be paid on August 15, 1997 to holders of record as of the
close of business on July 21, 1997. A tender of shares pursuant to the offer
will not deprive a shareholder of his or her right to receive the August 1997
dividend regardless of when such tender is made. Shares tendered and purchased
pursuant to the offer will not accrue any future dividends.
 
  Puget Sound Energy, its Board of Directors and its officers make no
recommendation to shareholders whether to tender any or all their shares.
 
                                          Sincerely,

       CITY TIME, ON FRIDAY, AUGUST 8, 1997, UNLESS THE OFFER IS EXTENDED.
       -------------------------------------------------------------------

        Puget Sound Energy, Inc. ("PSE"), a Washington corporation, invites the
holders of each series of PSE preferred stock listed above (each, a "Series of
Preferred") to tender any and all of their shares of a Series of Preferred
("Shares") for purchase at the purchase price per share listed above for the
Shares tendered, net to the seller in cash, upon the terms and subject to the
conditions set forth in the Offer to Purchase and in the accompanying Letter of
Transmittal for the Series of Preferred tendered. As to each Series of
Preferred, the Offer to Purchase, together with the applicable Letter of
Transmittal, constitutes the "Offer."  PSE will purchase all Shares validly
tendered and not withdrawn, upon the terms and subject to the conditions of the
Offer. See "Terms of the Offer--Extension; Termination; Amendments" and 
"--Certain Conditions of the Offer" in the Offer to Purchase.
        The Offer for each Series of Preferred is independent of the Offer for
any other Series of Preferred.
        Any shareholder desiring to tender all or any portion of his or her
Shares should either (1) complete and sign the applicable Letter of Transmittal
or a facsimile thereof in accordance with the instructions in the Letter of
Transmittal, mail or deliver it and any other required documents to the
Depositary at the addresses and in the manner indicated therein, and either
deliver the certificates representing Shares to the Depositary along with the
Letter of Transmittal or deliver such Shares pursuant to the procedure for book-
entry transfer set forth in "Terms of the Offer--Procedure for Tendering Shares"
in the Offer to Purchase or (2) request his or her broker, dealer, commercial
bank, trust company or nominee to effect the transaction for him or her. A
shareholder whose Shares are registered in the name of a broker, dealer,
commercial bank, trust company or nominee must contact such broker, dealer,
commercial bank, trust company or nominee if he or she desires to tender such
Shares. Any shareholder who desires to tender Shares and whose certificates
representing such Shares are not immediately available, or who cannot comply in
a timely manner with the procedure for book-entry transfer, should tender such
Shares by following the procedures for guaranteed delivery set forth in "Terms
of the Offer--Procedure for Tendering Shares" in the Offer to Purchase. Each
Series of Preferred has its own Letter of Transmittal, and only the applicable
Letter of Transmittal for a particular series or a Notice of Guaranteed Delivery
may be used to tender Shares of such series. PSE will, as provided in
Instruction 10 of the applicable Letter of Transmittal, pay a solicitation fee
of $0.50 per Share of Adjustable Rate Cumulative Preferred Stock, Series B ($25
par value) (the "Adjustable Rate Preferred") and $1.50 per Share of the other
two Series of Preferred (except that for transactions for beneficial owners
equal to or exceeding 10,000 Shares of the Adjustable Rate Preferred or 2,500
Shares of either of the other two Series of Preferred, PSE will pay a
solicitation fee of $0.25 per Share of Adjustable Rate Preferred and $1.00 per
Share of the other two Series of Preferred, provided that such fee will be paid
80% to the Dealer Manager named below and 20% to the Soliciting Dealer (as
defined in "Fees and Expenses" in the Offer to Purchase))for any Shares
tendered, accepted for payment and paid pursuant to the Offer.
        This transaction has not been approved or disapproved by the Securities
and Exchange Commission (the "Commission") nor has the Commission passed upon
the fairness or merits of such transaction nor upon the accuracy or adequacy
of the information contained in the Offer to Purchase. Any representation to the
contrary is unlawful.
        Neither PSE, its Board of Directors nor any of its officers makes any 
recommendation to any shareholder, as to whether to tender all or any Shares. 
Each shareholder must make his or her own decision as to whether to tender 
Shares and, if so, how many Shares to tender.
        The Adjustable Rate Preferred is listed and traded on the New York Stock
Exchange. There is no established trading market for the other two Series of
Preferred. The last reported sale price on the New York Stock Exchange for the
Adjustable Rate Preferred as of the close of business on July 10, 1997 (the last
trading day prior to the commencement of the Offer) was $24.75 on July 9, 1997.
Holders of Adjustable Rate Preferred are urged to obtain a current market
quotation, if available, for their Shares.

SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE
 
PURPOSE OF THE FORM
A person who is required to file an information return with the IRS must
obtain your correct TIN to report income paid to you, real estate
transactions, mortgage interest you paid, the acquisition or abandonment of
secured property, or contributions you made to an IRA. Use Form W-9 to furnish
your correct TIN to the requester (the person asking you to furnish your TIN)
and, when applicable, (1) to certify that the TIN you are furnishing is
correct (or that you are waiting for a number to be issued), (2) to certify
that you are not subject to backup withholding, and (3) to claim exemption
from backup withholding if you are an exempt payee. Furnishing your correct
TIN and making the appropriate certifications will prevent certain payments
from being subject to backup withholding.
 
Note: If a requester gives you a form other than a W-9 to request your TIN,
you must use the requester's form.
 
HOW TO OBTAIN A TIN
If you do not have a TIN, apply for one immediately. To apply, get Form SS-5,
Application for a Social Security Card (for individuals), from your local
office of the Social Security Administration, or Form SS-4, Application for
Employer Identification Number (for businesses and all other entities), from
your local IRS office.
 
To complete Form W-9 if you do not have a TIN, write "Applied for" in the
space for the TIN in Part I (or check box 2 of Substitute Form W-9), sign and
date the form, and give it to the requester. Generally, you must obtain a TIN
and furnish it to the requester by the time of payment. If the requester does
not receive your TIN by the time of payment, backup withholding, if
applicable, will begin and continue until you furnish your TIN to the
requester.
 
Note: Writing "Applied for" (or checking box 2 of the Substitute Form W-9) on
the form means that you have already applied for a TIN OR that you intend to
apply for one in the near future.
 
As soon as you receive your TIN, complete another Form W-9, include your TIN,
sign and date the form, and give it to the requester.
 
WHAT IS BACKUP WITHHOLDING?
Persons making certain payments to you after 1992 are required to withhold and
pay to the IRS 31% of such payments under certain conditions. This is called
"backup withholding." Payments that could be subject to backup withholding
include interest, dividends, broker and barter exchange transactions, rents,
royalties, nonemployee compensation, and certain payments from fishing boat
operators, but do not include real estate transactions.
 
If you give the requester your correct TIN, make the appropriate
certifications, and report all your taxable interest and dividends on your tax
return, your payments will not be subject to backup withholding. Payments you
receive will be subject to backup withholding if:
 
 1. You do not furnish your TIN to the requester, or
 2. The IRS notifies the requester that you furnished an incorrect TIN, or
 3. You are notified by the IRS that you are subject to backup withholding
    because you failed to report all your interest and dividends on your tax
    return (for reportable interest and dividends only), or
 4. You do not certify to the requester that you are not subject to backup
    withholding under 3 above (for reportable interest and dividend accounts
    opened after 1983 only), or
 5. You do not certify your TIN. This applies only to reportable interest,
    dividend, broker, or barter exchange accounts opened after 1983, or broker
    accounts considered inactive in 1983.
 
Except as explained in 5 above, other reportable payments are subject to
backup withholding only if 1 or 2 above applies. Certain payees and payments
are exempt from backup withholding and information reporting. See Payees and
Payments Exempt From Backup Withholding, below, and Example Payees and
Payments under Specific Instructions, below, if you are an exempt payee.
 
PAYEES AND PAYMENTS EXEMPT FROM BACKUP WITHHOLDING.
The following is a list of payees exempt from backup withholding and for which
no information reporting is required. For interest and dividends, all listed
payees are exempt except item (9). For broker transactions, payees listed in
(1) through (13) and a person registered under the Investment Advisers Act of
1940 who regularly acts as a broker are exempt. Payments subject to reporting
under sections 6041 and 6041A are generally exempt from backup withholding
only if made to payees described in items (1) through (7), except a
corporation that provides medical and health care services or bills and
collects payments for such services is not exempt from backup withholding or
information reporting. Only payees described in items (2) through (6) are
exempt from backup withholding for barter exchange transactions, patronage
dividends, and payments by certain fishing boat operations.
 
 (1) A corporation.
 (2) An organization exempt from tax under section 501(a), or an IRA, or a
     custodial account under section 403(b)(7).
 (3) The United States or any of its agencies or instrumentalities.
