and discontinue, an agreement with a clearing agency (the "SECURITIES 
DEPOSITORY") registered under Section 17A of the Exchange Act, which is the 
registered owner of all of the Senior Notes of a series, to establish 
procedures with respect to the Senior Notes of such series not inconsistent 
with the provisions of the Indenture; PROVIDED, HOWEVER, that any such 
agreement may provide:

          (i)  that the Senior Notes of such series may be represented by one or
     more global certificates; 

          (ii) that such Securities Depository is not required to present a
     Senior Note of such series to the Trustee in order to receive a partial
     payment of principal;

                                      -23-



          (iii)     that a legend referring to such agreement shall appear on
     each Senior Note of such series so long as the Senior Notes of such series
     are subject to such agreement; and

          (iv) that provisions for notice to such Securities Depository which
     are different from notice provisions in the Indenture, may be set forth
     therein.

          Neither the Company nor the Trustee will have any responsibility or 
obligation to any Securities Depository, to any direct or indirect 
participant (a "PARTICIPANT") in the book entry system of any Securities 
Depository, or to the purchasers (the "BENEFICIAL OWNERS") of an interest in 
the Senior Notes of such series from a Participant with respect to (A) the 
accuracy of any records maintained by the Securities Depository or by any 
Participant; (B) the payment by the Securities Depository or by any 
Participant of any amount due to any Beneficial Owner in respect of the 
principal amount or redemption price of, or interest on, any Senior Notes of 
such series; (C) the delivery of any notice by the Securities Depository or 
any Participant; (D) the selection of the Beneficial Owners to receive 
payment in the event of any partial redemption of the Senior Notes of such 
series; or (E) any other action taken by the Securities Depository or any 
Participant.

SECTION 2.03.  FORM AND DATING.

          The Senior Notes and the Trustee's certificate of authentication 
shall be substantially in the form of Exhibit A through Exhibit H hereto 
(which shall be a part of this Indenture) in respect of the Initial Series 
Senior Notes, or as specifically provided in the Supplemental Indenture that 
creates any other series of Senior Notes or in a Company Order pursuant to 
such Supplemental Indenture.  The Senior Notes may have notations, legends or 
endorsements approved as to form by the Company and required by law, stock 
exchange rules and agreements to which the Company is subject or usage.  Each 
Senior Note shall be dated the date of its authentication, unless otherwise 
specifically provided herein or in the Supplemental Indenture that creates a 
series of Senior Notes or in a Company Order pursuant to such Supplemental 
Indenture.  The Senior Notes shall be issuable only in denominations of 
$1,000 and integral multiples thereof.

          The terms and provisions contained in the Senior Notes shall 
constitute, and are hereby expressly made, a part of this Indenture and the 
Company and the Trustee, by their execution and delivery of this Indenture 
and of any Supplemental Indenture creating any series of Senior Notes, 
expressly agree to such terms and provisions and to be bound thereby.

SECTION 2.04.  EXECUTION AND AUTHENTICATION.

          Two Officers of the Company shall sign the Senior Notes for the 
Company by manual or facsimile signature.  If an Officer of the Company whose 
signature is on a Senior Note no longer holds that office at the time a 
Senior Note is authenticated, the Senior Note shall nevertheless be valid.

                                     -24-



          A Senior Note shall not be valid until authenticated by the manual 
signature of the Trustee.  The signature shall be conclusive evidence that 
the Senior Note has been authenticated under this Indenture. 

          The Trustee shall, upon a written order of the Company signed by 
two Officers of the Company, authenticate Senior Notes for original issue up 
to the aggregate principal amount stated in paragraph 3 of the Initial Series 
Senior Notes, or as specifically provided in the Supplemental Indenture that 
creates any other series of Senior Notes or in a Company Order pursuant to 
such Supplemental Indenture.  The aggregate principal amount of Senior Notes 
outstanding at any time may not exceed such amount except as provided in 
Section 2.09 hereof.

          The Trustee may appoint an authenticating agent acceptable to the 
Company to authenticate Senior Notes.  An authenticating agent may 
authenticate Senior Notes whenever the Trustee may do so.  Each reference in 
this Indenture to authentication by the Trustee includes authentication by 
such agent.  An authenticating agent has the same rights as an Agent to deal 
with the Company.  

SECTION 2.05.  REGISTRAR AND PAYING AGENT.

          The Company shall maintain an office or agency where Senior Notes 
may be presented for registration of transfer or for exchange ("REGISTRAR") 
and an office or agency where Senior Notes may be presented for payment 
("PAYING AGENT").  The Registrar shall keep a register of the Senior Notes 
and of their transfer and exchange.  The Company may appoint one or more 
co-registrars and one or more additional paying agents.  The term "Registrar" 
includes any co-registrar and the term "Paying Agent" includes any additional 
paying agent.  The Company may change any Paying Agent or Registrar without 
prior notice to any Holder.  The Company shall notify the Trustee in writing 
of the name and address of any Agent not a party to this Indenture.  If the 
Company fail to appoint or maintain another entity as Registrar or Paying 
Agent, the Trustee shall act as such.  The Company may act as Paying Agent or 
Registrar.

          The Company initially appoints the Trustee to act as the Registrar 
and Paying Agent and agent for service of notices and demands in connection 
with the Senior Notes.

SECTION 2.06.  PAYING AGENT AND TO HOLD MONEY IN TRUST.

          The Company shall require each Paying Agent other than the Trustee 
or the Company itself to agree in writing that the Paying Agent will hold in 
trust for the benefit of Holders or the Trustee all money held by the Paying 
Agent for the payment of principal of, or premium, if any, on the Senior 
Notes, and will notify the Trustee in writing of any default by the Company 
in making any such payment.  While any such default continues, the Trustee 
may require a Paying Agent to pay all money held by it to the Trustee.  The 
Company at any time may require a Paying Agent to pay all money held 

                                      -25-



by it to the Trustee.  Upon payment over to the Trustee, the Paying Agent (if 
other than the Company) shall have no further liability for the money 
delivered to the Trustee.  If the Company acts as Paying Agent, it shall 
segregate and hold in a separate trust fund for the benefit of the Holders 
all money held by it as Paying Agent.  Upon any bankruptcy or reorganization 
proceedings relating to the Company, the Trustee shall serve as Paying Agent 
for the Senior Notes.

SECTION 2.07.  HOLDER LISTS.

          The Trustee shall preserve in as current a form as is reasonably 
practicable the most recent list available to it of the names and addresses 
of all Holders and shall otherwise comply with TIA Section 312(a).  If the 
Trustee is not the Registrar, the Company shall furnish to the Trustee at 
least seven Business Days before each interest payment date and at such other 
times as the Trustee may request in writing, a list in such form and as of 
such date as the Trustee may reasonably require of the names and addresses of 
the Holders of Senior Notes, including the aggregate principal amount of 
Senior Notes held by each thereof.

SECTION 2.08.  TRANSFER AND EXCHANGE.

          When Senior Notes are presented to the Registrar with a request to 
register the transfer or to exchange them for an equal principal amount of 
Senior Notes of other denominations, the Registrar shall register the 
transfer or make the exchange if its requirements for such transactions are 
met; PROVIDED, HOWEVER, that any Senior Note presented or surrendered for 
registration of transfer or exchange shall be duly endorsed or accompanied by 
a written instruction of transfer in form satisfactory to the Registrar and 
the Trustee duly executed by the Holder thereof or by his attorney duly 
authorized in writing.  To permit registrations of transfer and exchanges, 
the Company shall issue and the Trustee shall authenticate Senior Notes at 
the Registrar's request, subject to such rules as the Trustee may reasonably 
require.

          Neither the Company nor the Registrar shall be required (i) to 
issue, register the transfer of or exchange Senior Notes during a period 
beginning at the opening of business on a Business Day 15 days before the day 
of any selection of Senior Notes for redemption under Section 3.02 and ending 
at the close of business on the day of selection, (ii) to register the 
transfer of or exchange any Senior Note so selected for redemption in whole 
or in part, being redeemed in part or (iii) to register the transfer or 
exchange of a Senior Note between the record date and the next succeeding 
interest payment date.

          No service charge shall be made to any Holder of a Senior Note for 
any registration of transfer or exchange (except as otherwise expressly 
permitted herein), but the Company may require payment of a sum sufficient to 
cover any transfer tax or similar governmental charge payable in connection 
therewith (other than such transfer tax or similar governmental charge 
payable upon exchanges pursuant to Sections 2.12, 3.06, or 9.05 hereof, which 
shall be paid by the Company).

                                      -26-



          Prior to due presentment to the Trustee for registration of the 
transfer of any Senior Note, the Trustee, any Agent or the Company may deem 
and treat the Person in whose name any Senior Note is registered as the 
absolute owner of such Senior Note for the purpose of receiving payment of 
principal of, or premium, if any, on such Senior Note and for all other 
purposes whatsoever, whether or not such Senior Note is overdue, and neither 
the Trustee, any Agent or the Company shall be affected by notice to the 
contrary.

SECTION 2.09.  REPLACEMENT SENIOR NOTES.

          If any mutilated Senior Note is surrendered to the Trustee or the 
Company and the Trustee receives evidence to its satisfaction of the 
destruction, loss or theft of any Senior Note, the Company shall issue and 
the Trustee, upon the written order of the Company signed by two Officers of 
the Company, shall authenticate a replacement Senior Note if the Trustee's 
requirements for replacements of Senior Notes are met.  If required by the 
Trustee or the Company, an indemnity bond must be supplied by the Holder that 
is sufficient in the judgment of the Trustee and the Company to protect the 
Company, the Trustee, any Agent and any authenticating agent from any loss 
that any of them may suffer if a Senior Note is replaced.  The Company may 
charge for its expenses in replacing a Senior Note.

          Every replacement Senior Note shall constitute a valid obligation 
of the Company and shall evidence the same debt as the Senior Note for which 
it is a replacement.

SECTION 2.10.  OUTSTANDING SENIOR NOTES.

          The Senior Notes outstanding at any time are all the Senior Notes 
authenticated by the Trustee except for those canceled by it, those delivered 
to it for cancellation and those described in this Section as not 
outstanding. Except as set forth in Section 2.11 hereof, a Senior Note does 
not cease to be outstanding because the Company or an Affiliate of the 
Company holds the Senior Note.

          If a Senior Note is replaced pursuant to Section 2.09 hereof, it 
ceases to be outstanding unless the Trustee receives proof satisfactory to it 
that the replaced Senior Note is held by a bona fide purchaser.

          If the principal amount of any Senior Note is considered paid under 
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to 
accrue.

SECTION 2.11.  TREASURY SENIOR NOTES.

          In determining whether the Holders of the required principal amount 
of Senior Notes have concurred in any direction, waiver or consent, Senior 
Notes owned by the Company, any Subsidiary of the Company or any Affiliate of 
the Company shall be considered as though not 

                                      -27-



outstanding, except that for the purposes of determining whether the Trustee 
shall be protected in relying on any such direction, waiver or consent, only 
Senior Notes that a Trustee knows are so owned shall be so considered.  
Notwithstanding the foregoing, Senior Notes that are to be acquired by the 
Company, any Subsidiary of the Company or any Affiliate of the Company 
pursuant to an exchange offer, tender offer or other agreement shall not be 
deemed to be owned by the Company, a Subsidiary of the Company or an 
Affiliate of the Company until legal title to such Senior Notes passes to the 
Company, such Subsidiary or such Affiliate, as the case may be.

SECTION 2.12.  TEMPORARY SENIOR NOTES.

          Until definitive Senior Notes are ready for delivery, the Company 
may prepare and the Trustee shall authenticate temporary Senior Notes upon a 
written order of the Company signed by two Officers.  Temporary Senior Notes 
shall be substantially in the form of definitive Senior Notes but may have 
variations that the Company considers appropriate for temporary Senior Notes 
and as shall be reasonably acceptable to the Trustee.  Without unreasonable 
delay, the Company shall prepare and the Trustee, upon a written order of the 
Company signed by two Officers of the Company, shall authenticate definitive 
Senior Notes in exchange for temporary Senior Notes.  Holders of temporary 
Senior Notes shall be entitled to all of the benefits of this Indenture.

SECTION 2.13.  CANCELLATION.

          The Company at any time may deliver Senior Notes to the Trustee for 
cancellation.  The Registrar and Paying Agent shall forward to the Trustee 
any Senior Notes surrendered to them for registration of transfer, exchange 
or payment.  The Trustee and no one else shall cancel all Senior Notes 
surrendered for registration of transfer, exchange, payment, replacement or 
cancellation and shall destroy canceled Senior Notes (subject to the record 
retention requirement of the Exchange Act).  Certification of the destruction 
of all canceled Senior Notes shall be delivered to the Company.  The Company 
may not issue new Senior Notes to replace Senior Notes that they have paid or 
that have been delivered to the Trustee for cancellation.

SECTION 2.14.  RECORD DATE.

          The record date for purposes of determining the identity of Holders 
of the Senior Notes entitled to vote or consent to any action by vote or 
consent authorized or permitted under this Indenture shall be determined as 
provided for in TIA Section 316(c).

SECTION 2.15.  CUSIP NUMBER.

          The Company in issuing the Senior Notes may use a "CUSIP" number 
and, if it does so, the Trustee shall use the CUSIP number in notices of 
redemption or exchange as a convenience to Holders; PROVIDED that any such 
notice may state that no representation is made as to the correctness 

                                      -28-



or accuracy of the CUSIP number printed in the notice or on the Senior Notes 
and that reliance may be placed only on the other identification numbers 
printed on the Senior Notes. The Company will promptly notify the Trustee of 
any change in the CUSIP number.

                                    ARTICLE 3. 
                             REDEMPTION AND REPURCHASE

Section 3.01.  CERTAIN SENIOR NOTES REDEEMABLE; NOTICES TO TRUSTEE.

          Any Outstanding Senior Notes which are, by their terms, redeemable 
before maturity, at the option of the Company or pursuant to the requirements 
of this Indenture (or any Supplemental Indenture which created a series of 
Senior Notes), may be redeemed at such times,  in such amounts and at such 
prices as may be specified therein and in accordance with this Article 3. 

          If the Company elects to redeem any Initial Series Senior Notes 
pursuant to the optional redemption provisions of Section 3.07 hereof, it 
shall furnish to the Trustee, at least 45 days (unless shorter notice shall 
be satisfactory to the Trustee) but not more than 60 days before a redemption 
date, an Officers' Certificate setting forth (i) the clause of this Indenture 
pursuant to which the redemption shall occur, (ii) the redemption date, (iii) 
the principal amount of Senior Notes to be redeemed and (iv) the redemption 
price. The notice periods for redemption of other series of Senior Notes, if 
different from the foregoing, shall be set forth in the Supplemental 
Indenture which creates and establishes such series or a Company Order 
pursuant to such Supplemental Indenture.

SECTION 3.02.  SELECTION OF SENIOR NOTES TO BE REDEEMED.

          If less than all of the Outstanding Senior Notes are to be redeemed 
at any time, the Trustee shall select the Senior Notes to be redeemed among 
the Holders of the Senior Notes in compliance with the requirements of the 
principal national securities exchange, if any, on which the Senior Notes are 
listed or, if the Senior Notes are not so listed, on a PRO RATA basis, by lot 
or in accordance with any other method the Trustee considers fair and 
appropriate.  In the event of partial redemption by lot, the particular 
Senior Notes to be redeemed shall be selected, unless otherwise provided 
herein, not less than 30 nor more than 60 days prior to the redemption date 
by the Trustee from the outstanding Senior Notes not previously called for 
redemption.

          The Trustee shall promptly notify the Company in writing of the 
Senior Notes selected for redemption and, in the case of any Senior Note 
selected for partial redemption, the principal amount thereof to be redeemed. 
 Senior Notes and portions of Senior Notes selected shall be in amounts of 
$1,000 or whole multiples of $1,000; except that if all of the Senior Notes 
of a Holder are to be redeemed, the entire outstanding amount of Senior Notes 
held by such Holder, even if not a multiple of $1,000, shall be redeemed.  
Except as provided in the preceding sentence, provisions of this 

                                      -29-



Indenture that apply to Senior Notes called for redemption also apply to 
portions of Senior Notes called for redemption.

          In the event the Issuers are required to make an offer to redeem 
Senior Notes pursuant to Sections 3.09 and 4.10 hereof and the amount of the 
Net Proceeds from the Sale of Assets is not evenly divisible by $1,000, the 
Trustee shall promptly refund to the Company at the address set forth in 
Section 10.02 hereof of any remaining Net Proceeds.

SECTION 3.03.  NOTICE OF REDEMPTION.

          Subject to the provisions of Section 3.09 hereof, at least 30 days 
but not more than 60 days before a redemption date, the Company shall mail or 
cause to be mailed, by first class mail, a notice of redemption to each 
Holder whose Senior Notes are to be redeemed at its registered address.

          The notice shall identify the Senior Notes to be redeemed and shall
state:

          i.   the redemption date;

          ii.  the redemption price;

          iii. if any Senior Note is being redeemed in part, the portion of the
     principal amount of such Senior Note to be redeemed and that, after the
     redemption date, upon surrender of such Senior Note, a new Senior Note or
     Senior Notes in principal amount equal to the unredeemed portion shall be
     issued upon cancellation of the original Senior Note;

          iv.  the name and address of the Paying Agent;

          v.   that Senior Notes called for redemption must be surrendered to
     the Paying Agent to collect the redemption price;

          vi.  that, unless the Company defaults in making such redemption
     payment, interest on Senior Notes called for redemption ceases to accrue on
     and after the redemption date;

          vii. the paragraph of the Senior Notes and/or Section of this
     Indenture and/or of the Supplemental Indenture which created the series of
     Senior Notes pursuant to which the Senior Notes called for redemption are
     being redeemed; and

          viii.     that no representation is made as to the correctness or
     accuracy of the CUSIP number, if any, listed in such notice or printed on
     the Senior Notes.

                                     -30-



          At the Company's request, the Trustee shall give the notice of 
redemption in the Company's name and at the Company's expense; PROVIDED, 
HOWEVER, that the Company shall have delivered to the Trustee, at least 45 
days prior to the redemption date, an Officers' Certificate requesting that 
the Trustee give such notice and setting forth the information to be stated 
in such notice as provided in the preceding paragraph.

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.

          Once notice of redemption is mailed in accordance with Section 3.03 
hereof, Senior Notes called for redemption become irrevocably due and payable 
on the redemption date at the redemption price.  A notice of redemption may 
not be conditional.

SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.

          One Business Day prior to the redemption date, the Company shall 
deposit with the Trustee or with the Paying Agent money sufficient to pay the 
redemption price of and accrued interest on all Senior Notes to be redeemed 
on that date.  The Trustee or the Paying Agent shall promptly return to the 
Company any money deposited with the Trustee or the Paying Agent by the 
Company in excess of the amounts necessary to pay the redemption price of, 
and accrued interest on, all Senior Notes to be redeemed.

          If the Company complies with the provisions of the preceding 
paragraph, on and after the redemption date, interest shall cease to accrue 
on the Senior Notes or the portions of Senior Notes called for redemption, 
whether or not such Senior Notes are presented for payment.  If a Senior Note 
is redeemed on or after an interest record date but on or prior to the 
related interest payment date, then any accrued and unpaid interest shall be 
paid to the Person in whose name such Senior Note was registered at the close 
of business on such record date.  If any Senior Note called for redemption 
shall not be so paid upon surrender for redemption because of the failure of 
the Company to comply with the preceding paragraph, interest shall be paid on 
the unpaid principal, from the redemption date until such principal is paid, 
and to the extent lawful on any interest not paid on such unpaid principal, 
in each case at the rate provided in the Senior Notes and in Section 4.01 
hereof.

SECTION 3.06.  SENIOR NOTES REDEEMED IN PART.

          Upon surrender of a Senior Note that is redeemed in part, the 
Company shall issue and, upon the Company's written request, the Trustee 
shall authenticate for the Holder at the expense of the Company a new Senior 
Note equal in principal amount to the unredeemed portion of the Senior Note 
surrendered.

                                     -31-



SECTION 3.07.  OPTIONAL AND SPECIAL REDEMPTION OF INITIAL SERIES SENIOR NOTES.

          (a)  Except as provided in subparagraphs (b), (c) and (d) below, 
the Initial Series Senior Notes may not be redeemed at the option of the 
Company prior to maturity.

          (b)  The Series A through G Senior Notes are redeemable by the 
Company at any time, in whole or in part, upon not less than 30 nor more than 
60 days' notice, in cash at a redemption price equal to 100% of the principal 
amount thereof plus accrued and unpaid interest through the redemption date 
plus the Make-Whole Premium.

          (c)  The Company shall have the option to redeem the Senior 
Discount Notes prior to July 1, 2003 at any time, in whole or in part, upon 
not less than 30 nor more than 60 days' notice, in cash at a redemption price 
equal to 100% of the Accreted Value thereof plus the Make-Whole Premium.  On 
and after July 1, 2003, the Company shall have the option to redeem the 
Senior Discount Notes, in whole or in part, upon not less than 30 nor more 
than 60 days' notice, in cash at the redemption prices (expressed as 
percentages of the principal amount) set forth below plus accrued and unpaid 
interest thereon, if any, to the applicable redemption date, if redeemed 
during the twelve-month period beginning on July 1 of the years indicated 
below:



          YEAR                           PERCENTAGE
          ----                           ----------
                                      
          2003                                      %
          2004                                      %
          2005                                      %
          2006 and thereafter                  100.0%


          (d)  Notwithstanding the provisions of subparagraph (b) above, the 
Company may, at its option, by delivering a notice of redemption at any time 
during the period from April 1, 1999 through December 31, 2000, use all or a 
portion of the Net Proceeds from any sale or sales of Fossil and Hydro 
Generating Assets to redeem up to $500,000,000 aggregate principal amount of 
the Senior Notes in Series B through F at a cash redemption price equal to 
100% of the principal amount thereof plus accrued and unpaid interest 
thereon, if any, through the date of redemption.  The Company shall effect a 
redemption of Senior Notes pursuant to this provision such that, following 
such redemption, the percentage of Senior Notes in each of Series B through F 
that remain outstanding (calculated for each series by dividing the aggregate 
principal amount of Senior Notes outstanding by the aggregate principal 
amount of Senior Notes originally issued) is as near to identical as 
reasonably practicable.  Any such redemption must occur within 120 days 
following the receipt by the Company of the Net Proceeds that are being used 
to effect the redemption.

                                      -32-



          (e)  Any redemption pursuant to this Section 3.07 shall be made 
pursuant to the provisions of Sections 3.01 through 3.06 hereof.

SECTION 3.08.  MANDATORY REDEMPTION.

          Except as set forth under Sections 4.10 and 4.15 hereof, the 
Company shall not be required to make mandatory repurchase, redemption or 
sinking fund payments with respect to the Initial Series Senior Notes.

SECTION 3.09.  OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

          In the event that, pursuant to Section 4.10 hereof, the Company 
shall be required to commence an Asset Sale Offer, it shall follow the 
procedures specified below.

          The Asset Sale Offer shall remain open for a period of 20 Business 
Days following its commencement and no longer, except to the extent that a 
longer period is required by applicable law (the "OFFER PERIOD").  No later 
than five Business Days after the termination of the Offer Period (the 
"PURCHASE DATE"), the Company shall purchase the principal amount (or 
principal amount at maturity, as the case may be) of Senior Notes required to 
be purchased pursuant to Section 4.10 hereof (the "OFFER AMOUNT") or, if less 
than the Offer Amount has been tendered, all Senior Notes tendered in 
response to the Asset Sale Offer.  Payment for any Senior Notes so purchased 
shall be made in the same manner as interest payments are made.

          The Company shall comply with any tender offer rules under the 
Exchange Act which may then be applicable, including Rule 14e-1, in 
connection with any offer required to be made by the Company to repurchase 
the Senior Notes as a result of an Asset Sale Offer.  To the extent that the 
provisions of any securities laws or regulations conflict with provisions of 
this Section 3.09, the Company shall comply with the applicable securities 
laws or regulations and shall not be deemed to have breached its obligations 
hereunder by virtue thereof.

          If the Purchase Date is on or after an interest record date and on 
or before the related interest payment date, any accrued and unpaid interest 
shall be paid to the Person in whose name a Senior Note is registered at the 
close of business on such record date, and no additional interest shall be 
payable to Holders who tender Senior Notes pursuant to the Asset Sale Offer.

          Upon the commencement of an Asset Sale Offer, the Company shall 
send, by first class mail, a notice to the Trustee and each of the Holders, 
with a copy to the Trustee.  The notice shall contain all instructions and 
materials necessary to enable such Holders to tender Senior Notes pursuant to 
the Asset Sale Offer.  The Asset Sale Offer shall be made to all Holders.  
The notice, which shall govern the terms of the Asset Sale Offer, shall state:

                                      -33-



          (a)  that the Asset Sale Offer is being made pursuant to this Section
     3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer
     shall remain open;

          (b)  the Offer Amount, the purchase price and the Purchase Date;

          (c)  that any Senior Note not tendered or accepted for payment shall
     continue to accrue interest;

          (d)  that, unless the Company defaults in making such payment, any
     Senior Note accepted for payment pursuant to the Asset Sale Offer shall
     cease to accrue interest after the Purchase Date;

          (e)  that Holders electing to have a Senior Note purchased pursuant to
     an Asset Sale Offer may elect only to have all of such Senior Note
     purchased and may not elect to have only a portion of such Senior Note
     purchased;

          (f)  that Holders electing to have a Senior Note purchased pursuant to
     any Asset Sale Offer shall be required to surrender the Senior Note, with
     the form entitled "Option of Holder to Elect Purchase" on the reverse of
     the Senior Note completed, or transfer by book-entry transfer, to the
     Company, a depositary (if appointed by the Company) or a Paying Agent at
     the address specified in the notice at least three days before the Purchase
     Date;

          (g)  that Holders shall be entitled to withdraw their election if the
     Company, the depositary or the Paying Agent, as the case may be, receive,
     not later than the expiration of the Offer Period, a telegram, telex,
     facsimile transmission or letter setting forth the name of the Holder, the
     principal amount of the Senior Note the Holder delivered for purchase and a
     statement that such Holder is withdrawing his election to have such Senior
     Note purchased;

          (h)  that, if the aggregate principal amount (or principal amount at
     maturity, as the case may be) of Senior Notes surrendered by Holders
     exceeds the Offer Amount, the Company shall select the Senior Notes to be
     purchased on a PRO RATA basis (with such adjustments as may be deemed
     appropriate by the Company so that only Senior Notes in denominations of
     US$1,000, or integral multiples thereof, shall be purchased); and

          (i)  that Holders whose Senior Notes were purchased only in part shall
     be issued new Senior Notes equal in principal amount to the unpurchased
     portion of the Senior Notes surrendered (or transferred by book-entry
     transfer).

          On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a PRO RATA basis to the extent necessary, the
Offer Amount of Senior Notes or portions 

                                      -34-



thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer 
Amount has been tendered, all Senior Notes tendered, and shall deliver to the 
Trustee an Officers' Certificate stating that such Senior Notes or portions 
thereof were accepted for payment by the Company in accordance with the terms 
of this Section 3.09. The Company, the depositary or the Paying Agent, as the 
case may be, shall promptly (but in any case not later than five days after 
the Purchase Date) mail or deliver to each tendering Holder an amount equal 
to the purchase price of the Senior Notes tendered by such Holder and 
accepted by the Company for purchase, and the Company shall promptly issue a 
new Senior Note, and the Trustee, upon written request from the Company shall 
authenticate and mail or deliver such new Senior Note to such Holder, in a 
principal amount equal to any unpurchased portion of the Senior Note 
surrendered.  Any Senior Note not so accepted shall be promptly mailed or 
delivered by the Company to the Holder thereof.  The Company shall publicly 
announce the results of the Asset Sale Offer on the Purchase Date.

          Other than as specifically provided in this Section 3.09, any 
purchase pursuant to this Section 3.09 shall be made pursuant to the 
provisions of Sections 3.01 through 3.06 hereof.  No repurchase of Senior 
Notes under this Section 3.09 shall be deemed to be a redemption of Senior 
Notes.

premium, if any, and interest on the Senior Notes on the dates and in the 
manner provided in the Senior Notes.  Principal, and premium, if any, shall 
be considered paid on the date due if the Paying Agent, if other than the 
Company, holds as of 10:00 a.m. Eastern Time on the due date money deposited 
by the Company in immediately available funds and designated for and 
sufficient to pay all principal, and premium, if any, then due.  Such Paying 
Agent shall return to the Company, no later than five Business Days following

any proceeding under any Bankruptcy Law) on overdue principal and premium, if 
any, at the rate equal to 1% per annum in excess of the then applicable 
interest rate on the Senior Notes to the extent lawful.

SECTION 4.02.   MAINTENANCE OF OFFICE OR AGENCY.

          The Company shall maintain in the Borough of Manhattan, the City of 
New York, an office or agency (which may be an office of the Trustee or an 
affiliate of the Trustee, Registrar or co-registrar) where Senior Notes may 
be surrendered for registration of transfer or for exchange and 

                                     -35-



where notices and demands to or upon the Company in respect of the Senior 
Notes and this Indenture may be served.  The Company shall give prompt 
written notice to the Trustee of the location, and any change in the 
location, of such office or agency.  If at any time the Company shall fail to 
maintain any such required office or agency or shall fail to furnish the 
Trustee with the address thereof, such presentations, surrenders, notices and 
demands may be made or served at the Corporate Trust Office of the Trustee.

          The Company may also from time to time designate one or more other 
offices or agencies where the Senior Notes may be presented or surrendered 
for any or all such purposes and may from time to time rescind such 
designations; PROVIDED, HOWEVER, that no such designation or rescission shall 
in any manner relieve the Company of its obligations to maintain an office or 
agency in the Borough of Manhattan, the City of New York for such purposes.  
The Company shall give prompt written notice to the Trustee of any such 
designation or rescission and of any change in the location of any such other 
office or agency.

Trustee as one such office or agency of the Company in accordance with 
Section 2.05.

them with the SEC, copies of the current, quarterly and annual reports and of

any of the foregoing as the SEC may by rules and regulations prescribe) that 
the Company is required to file with the SEC pursuant to Section 13 or 15(d) 
of the Exchange Act.  If the Company is not subject to the requirements of 
Section 13 or 15(d) of the Exchange Act, the Company shall nevertheless file 
with the SEC and the Trustee, on the date upon which it would have been 
required to file with the SEC, financial statements, including any notes 
thereto (and with respect to annual reports, an auditor's report by a firm of 
established national reputation, upon which the Trustee may conclusively 
rely), and a "Management's Discussion and Analysis of Financial Condition and 
Results of Operations," both comparable to that which the Company would have 
been required to include in such annual reports, information, documents or 
other reports on Forms 8-K, 10-Q and 10-K if the Company were subject to the 
requirements of Section 13 or 15(d) of the Exchange Act; PROVIDED, HOWEVER, 
that the Company shall not be required to register under the Exchange Act by 
virtue of this provision, if it were not otherwise required to do so.

the end of each fiscal year, an Officers' Certificate stating that a review 
of the activities of the Company and its Restricted Subsidiaries during the 
preceding fiscal year has been made under the supervision of the signing 
Officers with a view to determining whether the Company and its Restricted 
Subsidiaries have 

                                     -36-



kept, observed, performed and fulfilled their obligations under this 
Indenture and further stating, as to each such Officer signing such 
certificate, that to the best of his or her knowledge the Company has kept, 
observed, performed and fulfilled each and every covenant contained in this 
Indenture and is not in default in the performance or observance of any of 
the terms, provisions and conditions of this Indenture (or, if a Default or 
Event of Default shall have occurred, describing all such Defaults or Events 
of Default of which he or she may have knowledge and what action the Company 
is taking or proposes to take with respect thereto) and that to the best of 
his or her knowledge no event has occurred and remains in existence by reason 
of which payments on account of the principal of the Senior Notes is 
prohibited or if such event has occurred, a description of the event and what 
action the Company is taking or proposes to take with respect thereto.

          (b)  So long as not contrary to the then current recommendations of 
the American Institute of Chartered Accountants, the year-end financial 
statements delivered pursuant to Section 4.03(a) above shall be accompanied 
by a written statement of the Company's independent public accountants (who 
shall be a firm of established national reputation) that in making the 
examination necessary for certification of such financial statements, nothing 
has come to their attention that would lead them to believe that the Company 
have violated any of the financial provisions of Sections 4.01, 4.07, 4.09 
and 4.12 or, if any such violation has occurred, specifying the nature and 
period of existence thereof, it being understood that such accountants shall 
not be liable directly or indirectly to any Person for any failure to obtain 
knowledge of any such violation.

          (c)  The Company shall, so long as any of the Senior Notes are 
outstanding, deliver to the Trustee, forthwith upon any Officer becoming 
aware of any Default or Event of Default, an Officers' Certificate specifying 
such Default or Event of Default and what action the Company is taking or 
proposes to take with respect thereto.

SECTION 4.05.   TAXES.

          The Company shall pay, and shall cause each of its Restricted 
Subsidiaries to pay, prior to delinquency, all material taxes, assessments, 
and governmental levies except such as are contested in good faith and by 
appropriate proceedings or where the failure to effect such payment is not 
adverse in any material respect to the Holders of the Senior Notes.

SECTION 4.06.   STAY, EXTENSION AND USURY LAWS.

          The Company covenants (to the extent that it may lawfully do so) 
that it shall not at any time insist upon, plead, or in any manner whatsoever 
claim or take the benefit or advantage of, any stay, extension or usury law 
wherever enacted, now or at any time hereafter in force, that may affect the 
covenants or the performance of this Indenture; and the Company (to the 
extent that it may lawfully do so) hereby expressly waives all benefit or 
advantage of any such law, and covenants that it shall not, by resort to any 
such law, hinder, delay or impede the execution of any power herein granted 
to the 

                                     -37-



Trustee, but shall suffer and permit the execution of every such power as 
though no such law has been enacted.

SECTION 4.07.   RESTRICTED PAYMENTS.

          Prior to the Investment Grade Date, the Company shall not, and 
shall not permit any of its Restricted Subsidiaries to, directly or 
indirectly, (i) declare or pay any dividend or make any cash dividend or 
other distribution on account of the Company's or any of its Restricted 
Subsidiaries' Equity Interests, including, without limitation, any payment in 
connection with any merger or consolidation involving the Company (other than 
dividends or distributions payable in Equity Interests (other than 
Disqualified Stock) of the Company or any portion of a dividend or 
distribution by a Restricted Subsidiary of the Company that is payable to the 
Company or to any Wholly-Owned Restricted Subsidiary of the Company); (ii) 
purchase, redeem or otherwise acquire or retire for value from any Person 
other than the Company or a Wholly-Owned Restricted Subsidiary any Equity

Interests of the Company for other Equity Interests of the Company); or (iii) 
make any principal payment on, or purchase, redeem, defease or otherwise 
acquire or retire for value any Subordinated Indebtedness, except at final 
maturity; or (iv) make any Restricted Investment (all such payments and other 
actions set forth in clauses (i) through (iv) above being collectively 
referred to as "RESTRICTED PAYMENTS"), unless, at the time of and after 
giving effect to such Restricted Payments:

          (a)  no Default or Event of Default shall have occurred and be 
continuing or would occur as a consequence thereof; and 

          (b)  except in the case of any Restricted Investment, the Company 
would, at the time of such Restricted Payment, and after giving PRO FORMA 
effect thereto as if such Restricted Payment had been made at the beginning 
of the applicable four-quarter period, have a Fixed Charge Coverage Ratio of 
not less than 1.75 to 1 (calculated pursuant to Section 4.09 below); and

          (c)  such Restricted Payment, together with the aggregate of all 
other Restricted Payments made by the Company and its Restricted Subsidiaries 
after the Initial Issuance Date (excluding Restricted Payments permitted by 
clauses (iii), (iv), (v), (vi) or (vii) of the next succeeding paragraph), is 
less than the sum of (i) $50,000,000, PLUS (ii) 25% of an amount equal to the 
Operating Cash Flow of the Company for the period (taken as one accounting 
period) from the day after the Initial Issuance Date through the end of the 
Company's most recently ended fiscal quarter for which financial statements 
are available at the time of such Restricted Payment (or, if such Operating 
Cash Flow for such period is a deficit, less 100% of such deficit), PLUS 
(iii) 100% of the aggregate net cash proceeds received by the Company from 
the issuance or sale (other than pursuant to or in connection with the IPP 
Buyout) after the Initial Issuance Date of Equity Interests of the Company or 
of debt securities of the Company that have been converted into Equity 
Interests of the Company, PLUS (iv) 

                                     -38-



100% of the aggregate cash proceeds received by the Company from any payment 
in respect of any previously made Restricted Investment (but only to the 
extent that such amount is not reflected in Consolidated Net Income).

          The foregoing provisions shall not prohibit (i) the payment of 
dividends, whether paid in kind or in cash, or the satisfaction of mandatory 
redemption obligations, in respect of any Preferred Stock outstanding on the 
Initial Issuance Date in accordance with the terms thereof; (ii) the payment 
of any dividend within 60 days after the date of declaration thereof, if at 
said date of declaration such payment would have complied with the provisions 
of this Section 4.07, (iii) the redemption, repurchase, retirement or other 
acquisition of any Equity Interests of the Company in exchange for, or out of 
the proceeds of, the substantially concurrent sale (other than to a 
Restricted Subsidiary of the Company) of, other Equity Interests of the 
Company; (iv) defeasance, redemption or repurchase of Subordinated 
Indebtedness with the net cash proceeds of the substantially concurrent sale 
(other than to a Restricted Subsidiary of the Company) of Equity Interests of 
the Company or from an incurrence of Permitted Refinancing Indebtedness that 
consists of Subordinated Indebtedness, PROVIDED that the amount of any net 
cash proceeds that are utilized for any redemption, repurchase, retirement or 
other acquisition described in clauses (iii) and (iv) shall be excluded from 
clause (c)(iii) of the first paragraph of this Section 4.07; (v) the 
repurchase, redemption, or other acquisition or retirement for value of any 
Equity Interests of the Company or any Restricted Subsidiary of the Company 
held by any member of the Company's (or any of its Restricted Subsidiaries') 
management or for the purpose of providing Equity Interests for issuance 
under dividend reinvestment or employee benefits plans of the Company; (vi) 
any spin-off or other distribution to shareholders of the Generating Assets 
or the Oswego Plant or any portion thereof or any direct or indirect interest 
therein; and (vii) any dividend or other distribution of the Capital Stock of 
any Unrestricted Subsidiary, PROVIDED that in the case of each of clauses (i) 
and (ii) above, no Default or Event of Default shall have occurred and be 
continuing immediately after such transaction. 

          Not later than the date of making any Restricted Payment that 
relies on clause (c) of the first paragraph of this covenant to be permitted, 
and so long as the limitations contained in such clause apply, the Company 
shall deliver to the Trustee an Officer's Certificate stating that such 
Restricted Payment is permitted and setting forth the basis upon which the 
calculations required by such covenant were computed, which calculations may 
be based upon the Company's latest available financial statements.

SECTION 4.08.   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

          The Company shall not, and shall not permit any of its Restricted 
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer 
to exist or become effective any encumbrance or restriction on the ability of 
any such Restricted Subsidiary to (a) (i) pay dividends or make any other 
distributions to the Company or any of its Restricted Subsidiaries (A) on its 
Capital Stock or (B) with respect to any other interest or participation in, 
or measured by, its profits or (ii) pay any Indebtedness 

                                     -39-


owed to the Company or any of its Restricted Subsidiaries, (b) make loans or 
advances to the Company or any of its Restricted Subsidiaries or (c) transfer 
any of its properties or assets to the Company or any of its Restricted 
Subsidiaries, except for such encumbrances or restrictions existing under or 
by reason of (i) the First Mortgage Bonds, the Credit Facility, the 
Receivables Financing, the Pollution Control Obligations, the Securitization 
Transaction, the Indenture and the Senior Notes; (ii) applicable law or 
regulation; (iii) any instrument governing Indebtedness or Capital Stock of a 
Person acquired by the Company or any of its Restricted Subsidiaries as in 
effect at the time of such acquisition (except to the extent such 
Indebtedness was incurred in connection with or in contemplation of such 
acquisition), which encumbrance or restriction is not applicable to any 
Person, or the properties or assets of any Person, other than the Person, or 
the property or assets of the Person, so acquired; (iv) by reason of 
customary non-assignment provisions in leases entered into in the ordinary 
course of business and consistent with past practice; (v) purchase money 
obligations for property acquired in the ordinary course of business that 
impose restrictions of the nature described in clause (c) above in the 
property so acquired; (vi) any contract for the sale of 100% of the Capital 
Stock of a Restricted Subsidiary; or (vii) Permitted Refinancing 
Indebtedness, PROVIDED that the restrictions contained in the agreements 
governing such Permitted Refinancing Indebtedness are no more restrictive 
than those contained in the agreements governing the Indebtedness being 
refinanced.

SECTION 4.09.   INCURRENCE OF INDEBTEDNESS.

               Prior to the Investment Grade Date, the Company shall not, and 
shall not permit any of its Restricted Subsidiaries to, directly or 
indirectly create, incur, issue, assume, guaranty or otherwise become 
directly or indirectly liable, contingently or otherwise, with respect to 
(collectively, "INCUR"), any Indebtedness (including Acquired Debt) or issue 
any Disqualified Stock; PROVIDED, HOWEVER, that the Company and any of its 
Restricted Subsidiaries may incur  Indebtedness (including Acquired Debt) and 
issue Disqualified Stock if the Fixed Charge Coverage Ratio for the Company's 
most recently ended four full fiscal quarters for which financial statements 
are available immediately preceding the date on which such Indebtedness is 
incurred or Disqualified Stock is issued would have been at least 3.25 to 1, 
determined on a PRO FORMA basis (including a PRO FORMA application of the net 
proceeds therefrom), as if such Indebtedness had been incurred or such 
Disqualified Stock had been issued at the beginning of such four-quarter 
period. 

              The foregoing provisions will not apply to (i) Permitted 
Refinancing Indebtedness; (ii) the incurrence by the Company of any amount of 
Subordinated Indebtedness if the Fixed Charge Coverage Ratio for the 
Company's most recently ended four full fiscal quarters for which financial 
statements are available immediately preceding the date on which such 
Subordinated Indebtedness is incurred would have been at least 1.75 to 1 
(determined as in the immediately preceding paragraph); (iii) Permitted 
Hedging Agreements; (iv) borrowings under the Credit Facility in an amount 
not to exceed $804.4 million; and (v) intercompany Indebtedness between and 
among the Company and any of its Restricted Subsidiaries (except in a TIPES 
Transaction); PROVIDED, HOWEVER, that (A) any subsequent issuance or transfer 
of Equity Interests that results in any such Indebtedness being held by 


                                   40



a Person other than a Restricted Subsidiary and (B) any sale or other 
transfer of any such Indebtedness to a Person that is not either the Company 
or a Restricted Subsidiary shall be deemed, in each case, to constitute an 
incurrence of such Indebtedness by the Company or such Restricted Subsidiary, 
as the case may be.  

SECTION 4.10.  PROCEEDS OF CERTAIN ASSET SALES.

               The Company shall not, and shall not permit any of its 
Restricted Subsidiaries to, engage in a (A) Permitted Asset Swap unless the 
Company or Restricted Subsidiary receives property or assets with a Fair 
Value at least equal to the Fair Value of the property or assets swapped or 
(B) Sale of Assets unless (i) the Company (or the applicable Restricted 
Subsidiary, as the case may be) receives consideration at the time of such 
Sale of Assets at least equal to the Fair Value (evidenced by a resolution of 
the Board of Directors set forth in an Officers' Certificate delivered to the 
Trustee) of the assets of Equity Interests issued or sold or otherwise 
disposed of and (ii) except in connection with a sale of Fossil 
and Generating Assets or the Oswego Plant, at least 75% of the consideration 
received therefor by the Company or such Restricted Subsidiary is in the form 
of cash or Cash Equivalents; PROVIDED that if in the case of the sale of any 
Fossil and Generating Asset pursuant to the PowerChoice Agreement, the Board 
of Directors determines in good faith that the Company will receive the 
highest price by accepting a bid with consideration consisting of less than 
75% cash or Cash Equivalents, and the PSC approves the Company's acceptance 
of such bid, then the Company may accept such bid, and PROVIDED FURTHER, that 
in the case of any Sale of Assets (except a Securitization Transaction) that 
is consummated after the Investment Grade Date, the requirement of clause 
(ii) shall not apply.  For purposes of determining the Company's compliance 
with the requirements of the immediately preceding sentence, the amount of 
(x) any liabilities (as shown on the Company's or such Restricted 
Subsidiary's most recent balance sheet), of the Company or any Restricted 
Subsidiary (other than contingent liabilities and liabilities that are by 
their terms subordinated to the Senior Notes) that are assumed by the 
transferee of any such assets pursuant to a customary novation agreement or 
that otherwise releases the Company or such Restricted Subsidiary from 
further liability and (y) any notes or other obligations received by the 
Company or any such Restricted Subsidiary from such transferee that are 
immediately converted by the Company or such Restricted Subsidiary into cash 
shall be deemed to be cash for purposes of this provision (to the extent of 
the cash received).

               Within 180 days after the receipt of any Net Proceeds from a 
Securitization Transaction or a Sale of Assets consisting of Generating 
Assets, or within 360 days after the receipt of any Net Proceeds from any 
other Sale of Assets that is consummated prior to the Investment Grade Date, 
the Company shall (a) in the case of a Securitization Transaction, apply the 
cash portion of such Net Proceeds in accordance with the relevant statutory 
or regulatory requirements that govern such transaction or, if there are no 
such requirements, to reduce Senior Indebtedness, (b) in the case of a sale 
or other disposition of Generating Assets or the Oswego Plant, use not less 
than 85% (or 100% if the accepted bid requires less than 75% of the purchase 
price to be paid in cash or Cash Equivalents) of the cash portion of such Net 
Proceeds to reduce Senior Indebtedness, and (c) in the case of any 


                                    41



other Sale of Assets that is consummated prior to the Investment Grade Date, 
use 100% of such Net Proceeds for one or more of the following:  (i) to 
reduce Senior Indebtedness, (ii) to reinvest, or enter into an agreement with 
respect to the reinvestment of, such Net Proceeds in Related Assets, or (iii) 
make an offer to all Holders of Senior Notes (an "ASSET SALE OFFER") to 
purchase the maximum principal amount of Senior Notes that may be purchased 
out of such Net Proceeds, at an offer price in cash in an amount equal to 
100% of the principal amount thereof (in the case of the Series A through G 
Notes) or 100% of the principal amount at maturity of the Senior Discount 
Notes (if such purchase occurs on or after July 1, 2003) or 100% of the 
Accreted Value of the Senior Discount Notes (if such repurchase occurs prior 
to July 1, 2003) plus accrued and unpaid interest thereon, if any, to the 
date of purchase, in accordance with the procedures set forth in this 
Indenture. To the extent that the aggregate amount of Senior Notes tendered 
pursuant to an Asset Sale Offer is less than the amount of such Net Proceeds, 
the Company may use any remaining Net Proceeds for general corporate 
purposes.  If the aggregate principal amount of Senior Notes surrendered by 
Holders thereof exceeds the amount of such Net Proceeds, the Trustee shall 
select the Senior Notes to be purchased on a pro rata basis.  Upon completion 
of such offer to purchase, the amount of Net Proceeds shall be reset at zero. 
Pending the final application of any such Net Proceeds, the Company may 
otherwise invest such Net Proceeds in any manner that is not prohibited by 
this Indenture. 

SECTION 4.11.  TRANSACTION WITH AFFILIATES.

               The Company shall not, and shall not permit any of its 
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise 
dispose of any of their properties or assets to, or purchase any property or 
assets from, or enter into or make or amend any contract, agreement, 
understanding, loan, advance or guarantee with, or for the benefit of, any 
Affiliate (each of the foregoing, an "AFFILIATE TRANSACTION"), unless (i) 
such Affiliate Transaction is on terms that are no less favorable to the 
Company or the relevant Subsidiary than those that would have been obtained 
in a comparable transaction by the Company or Subsidiary with an unrelated 
Person; and (ii) the Company delivers to the Trustee (a) with respect to any 
Affiliate Transaction or series of related Affiliate Transactions involving 
aggregate consideration in excess of $10.0 million, a resolution of the Board 
of Directors set forth in an Officers' Certificate certifying that such 
Affiliate Transaction complies with clause (i) above and that such Affiliate 
Transaction has been approved by a majority of the disinterested members of 
the Board of Directors and (b) with respect to any Affiliate Transaction or 
series of related Affiliate Transactions involving aggregate consideration in 
excess of $50.0 million, an opinion as to the fairness to the Company or such 
Subsidiary of such Affiliate Transaction from a financial point of view 
issued by a nationally recognized expert in evaluating such transactions; 
PROVIDED that (v) any employment agreement entered into by the Company or its 
Subsidiaries in the ordinary course of business; (w) commercial transactions 
in the ordinary course of the utility business between or among the Company 
and/or its Restricted Subsidiaries; (x) Restricted Payments that are 
permitted by Section 4.07; (y) agreements or transactions entered into in

                                  42



the Company and its Restricted Subsidiaries and the Company's parent that are 
on terms permitted by the PSC, in each case, shall not be deemed Affiliate 
Transactions.

SECTION 4.12.  LIENS.

               The Company will not, and will not permit any of its 
Restricted Subsidiaries to, directly or indirectly, secure with a Lien on the 
property or assets of the Company or such Restricted Subsidiary, Other 
Indebtedness or Subordinated Indebtedness without making, or causing such 
Restricted Subsidiary to make, effective provision for securing the Senior 
Notes (i) in the case of a Lien securing Other Indebtedness, on an equal and 
ratable basis with the Lien securing such Other Indebtedness and (ii) in the 
case of a Lien securing Subordinated Indebtedness, on a basis such that the 
Lien securing the Senior Notes is senior in priority to the Lien securing 
such Subordinated Indebtedness, in each case until such time as such Other 
Indebtedness or Subordinated Indebtedness is no longer secured by a Lien.

SECTION 4.13.  CORPORATE EXISTENCE.

               Subject to Article 5 hereof, the Company shall do or cause to 
be done all things necessary to preserve and keep in full force and effect

existence of each of its Restricted Subsidiaries, in accordance with the 
respective organizational documents (as the same may be amended from time to 
time) of the Company or any such Restricted Subsidiary and (ii) the rights 
(charter and statutory), licenses and franchises of the Company and its 
Restricted Subsidiaries; PROVIDED, HOWEVER, that the Company shall not be 
required to preserve any such right, license or franchise, or the corporate, 
partnership or other existence of any of its Restricted Subsidiaries, if the 
Board of Directors shall determine that the preservation thereof is no longer 
desirable in the conduct of the business of the Company and its Restricted 
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in 
any material respect to the Holders of the Senior Notes.

SECTION 4.14.  OFFER TO REPURCHASE UPON CHANGE OF CONTROL TRIGGERING EVENT.

               (a)  Upon the occurrence of a Change of Control Triggering 
Event, each Holder of Senior Notes will have the right to require the Company 
to repurchase all or any part (equal to $1,000 or an integral multiple 
thereof) of such Holder's Senior Notes pursuant to the offer described below 
(the "CHANGE OF CONTROL OFFER") at an offer price in cash equal to (a) 101% 
of the aggregate principal amount thereof in the case of the Series A through 
G Senior Notes, (b) 101% of the principal amount at maturity of the Senior 
Discount Notes (if such repurchase occurs on or after July 1, 2003) or (c) 
101% of the Accreted Value of the Senior Discount Notes (if such repurchase 
occurs prior to July 1, 2003), plus accrued and unpaid interest thereon, if 
any, to the date of purchase (the "CHANGE OF CONTROL PAYMENT").  Within 
thirty days following any Change of Control Triggering Event, the Company 
shall mail a notice to each Holder describing the transaction or transactions 
that constitute 

                                    43



the Change of Control Triggering Event and offering to repurchase Senior 
Notes pursuant to the procedures described in this Section and described in 
such notice.  The notice will state: (1) that the Change of Control Offer is 
being made pursuant to this Section 4.14 and that all Senior Notes tendered 
will be accepted for payment; (2) the purchase price and the purchase date, 
which shall be at least 30 but not more than 60 days from the date such 
notice is mailed (the "CHANGE OF CONTROL PAYMENT DATE"); (3) that any Senior 
Note not tendered will continue to accrue interest; (4) that, unless the 
Company defaults in the payment of the Change of Control Payment, all Senior 
Notes accepted for payment pursuant to the Change of Control Offer shall 
cease to accrue interest after the Change of Control Payment Date; (5) that 
Holders  electing to have any Senior Notes purchased pursuant to a Change of 
Control Offer will be required to surrender the Senior Notes, with the form 
entitled "Option of Holder to Elect Purchase" on the reverse of the Senior 
Notes completed, to the Paying Agent at the address specified in the notice 
prior to the close of business on the third Business Day preceding the Change 
of Control Payment Date; (6) that Holders will be entitled to withdraw their 
election if the Paying Agent receives, not later than the close of business 
on the second Business Day preceding the Change of Control Payment Date, a 
telegram, telex, facsimile transmission or letter setting forth the name of 
the Holder, the principal amount of Senior Notes delivered for purchase, and 
a statement that such Holder is withdrawing his election to have the Senior 
Notes purchased; and (7) that Holders whose Senior Notes are being purchased 
only in part will be issued new Senior Notes equal in principal amount (or 
principal amount at maturity, as the case may be) to the unpurchased portion 
of the Senior Notes surrendered, which unpurchased portion must be equal to 
$1,000 in principal amount or an integral multiple thereof.  The Company 
shall comply with the requirements of Rule 14e-1 under the Exchange Act and 
any other securities laws and regulations thereunder to the extent such laws 
and regulations are applicable in connection with the repurchase of the 
Senior Notes as a result of a Change of Control.

               (b)  On the Change of Control Payment Date, the Company shall, 
to the extent lawful, (1) accept for payment all Senior Notes or portions 
thereof properly tendered pursuant to the Change of Control Offer, (2) 
deposit with the Paying Agent an amount equal to the Change of Control 
Payment in respect of all Senior Notes or portions thereof so tendered and 
(3) deliver or cause to be delivered to the Trustee the Senior Notes so 
accepted together with an Officers' Certificate stating the aggregate 
principal amount (or principal amount at maturity, as the case may be) of 
Senior Notes or portions thereof being purchased by the Company.  The Paying 
Agent shall promptly mail to each Holder of Senior Notes so tendered the 
Change of Control Payment for such Senior Notes, and the Trustee will 
promptly authenticate and mail (or cause to be transferred by book entry) to 
each Holder a new Senior Note equal in principal amount (or principal amount 
at maturity, as the case may be) to any unpurchased portion of the Senior 
Notes surrendered, if any; PROVIDED that each such new Senior Note will be in 
a principal amount of $1,000 or an integral multiple thereof.  The Company 
shall publicly announce the results of the Change of Control Offer on or as 
soon as practicable after the Change of Control Payment Date.


                                       44



               (c)  The Company shall not be required to make a Change of 
Control Offer upon a Change of Control Triggering Event if a third party 
makes the Change of Control Offer in the manner, at the times and otherwise 
in compliance with the requirements set forth in Sections 4.14(a) and 4.14(b) 
hereof and purchases all Senior Notes validly tendered and not withdrawn 
under such Change of Control Offer.

SECTION 4.15.  PAYMENTS FOR CONSENTS.

               Neither the Company nor any of its Subsidiaries may, directly 
or indirectly, pay or cause to be paid any consideration, whether by way of 
interest, fee or otherwise, to any Holder of any Senior Note of any series 
for or as an inducement to any consent, waiver or amendment of any of the 
terms or provisions of this Indenture or such Senior Notes unless such 
consideration is offered to be paid or agreed to be paid to all Holders of 
the Senior Notes of that series that consent, waive or agree to amend in the 
time frame set forth in the solicitation documents relating to such consent, 
waiver or agreement.

                               ARTICLE 5
                               SUCCESSORS

SECTION 5.01.   MERGER, CONSOLIDATION, OR SALE OF ASSETS.

               So long as the Senior Notes are outstanding, the Company may 
not, directly or indirectly, consolidate or merge with or into (whether or 
not the Company is the surviving corporation), or sell, assign, transfer, 
lease, convey or otherwise dispose of all or substantially all its assets in 
one or more related transactions, to another Person unless (i) the 
corporation formed by such consolidation or surviving in such merger or the 
Person that acquires by sale, assignment, transfer, conveyance or other 
disposition, or that leases, such assets (in each such case, the "SUCCESSOR 
ENTITY"), is a corporation organized and existing under the laws of the 
United States, any State thereof or the District of Columbia and expressly 
assumes the Company's obligations under the Indenture and  the Notes; (ii) 
immediately before and after such transaction no Default or Event of Default 
exists; and (iii) the Successor Entity (or the Company, in the case of a 
consolidation or merger in which the Company is the surviving entity) (A) has 
Consolidated Net Worth immediately after the transaction (but prior to any 
revaluation or recalculation of Consolidated Net Worth as of the date of the 
transaction relating to a carry-over basis (if any) of the assets acquired in 
the transaction (as determined in accordance with GAAP)) equal to or greater 
than the Consolidated Net Worth of the Company immediately prior to the 
transaction and (B) will, at the time of such transaction and after giving 
PRO FORMA effect thereto as if such transaction had occurred at the beginning 
of the applicable four-quarter period, have a Fixed Charge Coverage Ratio of 
not less than 1.75 to 1 (calculated pursuant to Section 4.09 above); PROVIDED 
that the limitations set forth in this clause (iii) shall not apply following 
the Investment Grade Date or to any merger or consolidation of the Company 
with or into a Restricted Subsidiary and PROVIDED FURTHER, that the 
limitations set forth above shall not apply to the sale or disposition by the 


                                   45



Company of the Generating Assets or the Oswego Plant (it being understood and 
agreed that the acquiror or transferee of such assets shall not qualify as a 
Successor Entity on the basis of having acquired all or substantially all of 
the Company's assets for purposes of this Article 5).

SECTION 5.02.   SUCCESSOR CORPORATION SUBSTITUTED.

               Upon any consolidation, amalgamation or merger, or any sale, 
assignment, transfer, lease, conveyance or other disposition of all or 
substantially all of the assets of the Company in accordance with Section 
5.01 hereof, the successor corporation formed by such consolidation or 
amalgamation or into or with which the Company is merged or to which such 
sale, assignment, transfer, lease, conveyance or other disposition is made 
shall succeed to, and be substituted for (so that from and after the date of 
such consolidation, amalgamation, merger, sale, lease, conveyance or other 
disposition, the provisions of this Indenture referring to the "COMPANY" 
shall refer instead to the successor corporation), and may exercise every 
right and power of the Company under this Indenture with the same effect as 
if such successor Person had been named as the Company herein; PROVIDED, 
HOWEVER, that the predecessor Company shall not be relieved from the 
obligation to pay the principal of, and premium, if any, on the Senior Notes 
except in the case of a transaction that meets the requirements of Section 
5.01 hereof.

                               ARTICLE 6
                         DEFAULTS AND REMEDIES

SECTION 6.01.   EVENTS OF DEFAULT.

               Each of the following constitutes an "EVENT OF DEFAULT":

               (i)   default by the Company for 60 days in the payment when due
          of interest on the Senior Notes;

               (ii)  default by the Company in the payment when due of the
          principal of, or premium, if any, on the Senior Notes;

               (iii) failure by the Company to comply with Sections 4.07,
          4.09 or 5.01 hereof;

               (iv)  failure by the Company for 60 days after written notice to
          the Company  by the Trustee, or written notice to the Company and the
          Trustee by the Holders of 25% or more in an aggregate principal 
          amount (or principal amount at maturity, as the case may be) of the 
          Senior Notes, to comply with any of its agreements in the Indenture 
          or the Senior Notes;


                                      46



               (v)   default by the Company under any mortgage, indenture or 
           instrument under which there may be issued or by which there may 
           be secured or evidenced any Indebtedness of the Company or any of 
           its Restricted Subsidiaries (or the payment of which is guaranteed 
           by the Company or any of its Restricted Subsidiaries), whether 
           such Indebtedness or Guarantee now exists, or is created after the 
           date hereof, which default (a) is caused by a failure to pay the 
           principal of such Indebtedness at the stated maturity of such 
           Indebtedness after the expiration of the grace period provided in 
           such Indebtedness (a "PAYMENT DEFAULT") or (b) results in the 
           acceleration of such Indebtedness prior to its stated maturity 
           and, in each case, the principal amount of any such Indebtedness, 
           together with the principal amount of any other such Indebtedness 
           under which there has been a Payment Default or the maturity of 
           which has been so accelerated, aggregates $50.0 million or more;

               (vi)  failure by the Company or any of its Restricted 
           Subsidiaries to pay a final judgment or final judgments not 
           otherwise covered by insurance for the payment of money entered by 
           a court or courts of competent jurisdiction against the Company or 
           any of its Subsidiaries and such judgment or judgments are not 
           paid, discharged or stayed for a period of 60 days, PROVIDED that 
           the aggregate of all such undischarged judgments exceeds $50.0 
           million;

               (vii) the Company or any of its Significant Subsidiaries 
           pursuant to or within the meaning of any Bankruptcy Law:

                       (a)  commences a voluntary Case,

                       (b)  consents to the entry of an order for relief 
                        against it in an involuntary Case,

                       (c)  consents to the appointment of a Custodian of it 
                 or for all or substantially all of its property,

                       (d)  makes a general assignment for the benefit of its
                 creditors, or

                       (e)  generally is not paying its debts as they become 
                 due; or

               (viii)    a court of competent jurisdiction enters an order or
           decree under any Bankruptcy Law that:

                       (a)  is for relief against the Company or any of its
                 Significant Subsidiaries in an involuntary Case;


                                      47



                       (b)  appoints a Custodian of the Company or any of its
                 Significant Subsidiaries or for all or substantially all of the
                 property of the Company or any of its Significant Subsidiaries;
                 or

                       (c)  orders the liquidation of the Company or any of its
                 Significant Subsidiary; and, in each case, the order or decree
                 remains unstayed and in effect for 60 consecutive days.

          The term "CUSTODIAN" means any receiver, trustee, assignee, 
liquidator or similar official under any Bankruptcy Law.  The term "CASE" 
means an application, petition, action, case or other proceeding (including 
the filing of a notice of intention to file a proposal) before any court, 
tribunal or other governmental authority under any applicable Bankruptcy Law 
(foreign or domestic).

          In the case of any Event of Default pursuant to the provisions of 
this Section 6.01 occurring by reason of any willful action (or inaction) 
taken (or not taken) by or on behalf of the Company with the intention of 
avoiding payment of the premium that the Company would have had to pay if the 
Company then had elected to redeem the Senior Notes pursuant to Sections 3.07 
or 4.14 hereof, an equivalent premium shall also become and be immediately 
due and payable to the extent permitted by law upon the acceleration of the 
Senior Notes, anything in this Indenture or in the Senior Notes to the 
contrary notwithstanding. 

SECTION 6.02.   ACCELERATION.

          If any Event of Default (other than an Event of Default specified in
clause (vii) or (viii) of Section 6.01 hereof with respect to the Company or any
Significant Subsidiary) occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount (or principal amount at maturity, as the case
may be) of the then outstanding Senior Notes of any series affected by an Event
of Default may declare all the Senior Notes of such Series to be due and payable
immediately.  Upon any such declaration, the Senior Notes shall become due and
payable immediately.  Notwithstanding the foregoing, if an Event of Default
specified in clause (vii) or (viii) of Section 6.01 hereof occurs with respect
to the Company or any of its Significant Subsidiaries, all outstanding Senior
Notes shall be due and payable immediately without further action or notice. 
The Holders of a majority in aggregate principal amount (or principal amount at
maturity, as the case may be) of the then outstanding Senior Notes of any series
affected by an Event of Default by written notice to the Trustee may on behalf
of all of the Holders of such series rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default (except nonpayment of principal, interest
or premium that has become due solely because of the acceleration) have been
cured or waived.  Except as provided in Section 6.01 hereof, in the event of any
such acceleration of Senior Notes, the Company will become obligated to pay the
aggregate principal amount and accrued interest (or Accreted Value on the Senior
Discount Notes if prior to July 1, 2003) of the Senior Notes immediately.


                               48



SECTION 6.03.   OTHER REMEDIES.

               If an Event of Default occurs and is continuing, the Trustee may 
pursue any available remedy to collect the payment of principal, and premium, 
if any, on the Senior Notes or to enforce the performance of any provision of 
the Senior Notes or this Indenture.

               The Trustee may maintain a proceeding even if it does not 
possess any of the Senior Notes or does not produce any of them in the 
proceeding.  A delay or omission by the Trustee or any Holder of a Senior 
Note in exercising any right or remedy accruing upon an Event of Default 
shall not impair the right or remedy or constitute a waiver of or 
acquiescence in the Event of Default.  All remedies are cumulative to the 
extent permitted by law.

SECTION 6.04.   WAIVER OF PAST DEFAULTS.

               Holders of not less than a majority in aggregate principal 
amount (or principal amount at maturity, as the case may be) of the then 
outstanding Senior Notes that would be materially adversely affected by such 
waiver by notice to the Trustee may on behalf of the Holders of all of the 
Senior Notes waive an existing Default or Event of Default and its 
consequences hereunder, except a continuing Default or Event of Default in 
the payment of interest on, or the principal of, or premium of, if any, the 
Senior Notes.  Upon any such waiver, such Default shall cease to exist, and 
any Event of Default arising therefrom shall be deemed to have been cured for 
every purpose of this Indenture; but no such waiver shall extend to any 
subsequent or other Default or impair any right consequent thereon.

SECTION 6.05.   CONTROL BY MAJORITY.

               Holders of a majority in principal amount (or principal amount at
maturity, as the case may be) of the then outstanding Senior Notes of any series
affected by an Event of Default may direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee or
exercising any trust or power conferred on it.   However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture that the
Trustee determines may be unduly prejudicial to tile rights of other Holders of
Senior Notes or that may involve the Trustee in personal liability.

SECTION 6.06.   LIMITATION ON SUITS.

               A Holder of a Senior Note may pursue a remedy with respect to 
this Indenture or the Senior Notes only if:

               (a)  the Holder of a Senior Note gives to the Trustee written 
     notice of a continuing Event of Default;


                                  49



               (b)  the Holders of at least 25% in principal amount (or 
     principal amount at maturity, as the case may be) of the then outstanding 
     Senior Notes make a written request to the Trustee to pursue the remedy;

               (c)  such Holder of a Senior Note or Holders of Senior Notes 
     offer and, if requested, provide to the Trustee indemnity satisfactory to 
     the Trustee against any loss, liability or expense;

               (d)  the Trustee does not comply with the request within 60 days 
     after receipt of the request and the offer and, if requested, the 
     provision of indemnity; and

               (e)  during such 60-day period the Holders of a majority in 
     principal amount (or principal amount at maturity, as the case may be) 
     of the then outstanding Senior Notes do not give the Trustee a direction 
     inconsistent with the request.

A Holder of a Senior Note may not use this Indenture to prejudice the rights 
of another Holder of a Senior Note or to obtain a preference or priority over 
another Holder of a Senior Note.

SECTION 6.07.   RIGHTS OF HOLDERS OF SENIOR NOTES TO RECEIVE PAYMENT.

               Notwithstanding any other provision of this Indenture, the 
right of any Holder of a Senior Note to receive payment of principal and 
premium, if any, on the Senior Note, on or after the respective due dates 
expressed in the Senior Note (including in connection with an offer to 
purchase), or to bring suit for the enforcement of any such payment on or 
after such respective dates, shall not be impaired or affected without the 
consent of such Holder.

SECTION 6.08.   COLLECTION SUIT BY TRUSTEE.

               If an Event of Default specified in Section 6.01(i) or (ii) 
hereof occurs and is continuing, the Trustee is authorized to recover 
judgment in its own name and as trustee of an express trust against the 
Company for the whole amount of principal of, and premium, if any, remaining 
unpaid on the Senior Notes and interest on overdue principal and, to the 
extent lawful, such further amount as shall be sufficient to cover the costs 
and expenses of collection, including the reasonable compensation, expenses, 
disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09.   TRUSTEE MAY FILE PROOFS OF CLAIM.

               The Trustee is authorized to file such proofs of claim and 
other papers or documents as may be necessary or advisable in order to have 
the claims of the Trustee (including any claim for the reasonable 
compensation, expenses, disbursements and advances of the Trustee, its agents 
and counsel) and the Holders of the Senior Notes allowed in any judicial 
proceedings relative to the Company (or 


                                   50



any other obligor upon the Senior Notes), its creditors or its property and 
shall be entitled and empowered to collect, receive and distribute any money 
or other property payable or deliverable on any such claims and any custodian 
in any such judicial proceeding is hereby authorized by each Holder to make 
such payments to the Trustee, and in the event that the Trustee shall consent 
to the making of such payments directly to the Holders, to pay to the Trustee 
any amount due to it for the reasonable compensation, expenses, disbursements 
and advances of the Trustee, its agents and counsel, and any other amounts 
due the Trustee under Section 7.07 hereof.  To the extent that the payment of 
any such compensation, expenses, disbursements and advances of the Trustee, 
its agents and counsel, and any other amounts due the Trustee under Section 
7.07 hereof out of the estate in any such proceeding, shall be denied for any 
reason, payment of the same shall be secured by a Lien on, and shall be paid 
out of, any and all distributions, dividends, money, securities and other 
properties that the Holders may be entitled to receive in such proceeding 
whether in liquidation or under any plan of reorganization or arrangement or 
otherwise.  Nothing herein contained shall be deemed to authorize the Trustee 
to authorize or consent to or accept or adopt on behalf of any Holder any 
plan of reorganization, arrangement, adjustment or composition affecting the 
Senior Notes or the rights of any Holder, or to authorize the Trustee to vote 
in respect of the claim of any Holder in any such proceeding.

SECTION 6.10.  PRIORITIES.

               If the Trustee collects any money pursuant to this Article, it 
shall pay out the money in the following order:

               FIRST: to the Trustee, its agents and attorneys for amounts 
due under Section 7.07 hereof, including payment of all compensation, expense 
and liabilities incurred, and all advances made, by the Trustee and the costs 
and expenses of collection, including the costs of its agents and counsel;

               SECOND: to Holders of Senior Notes for amounts due and unpaid 
on the Senior Notes for principal, and premium, if any, ratably, without 
preference or priority of any kind, according to the amounts due and payable 
on the Senior Notes for principal, and premium, if any, respectively; and

               THIRD: to the Company or to such party as a court of competent 
jurisdiction shall direct.

               The Trustee may fix a record date and payment date for any 
payment to Holders of Senior Notes pursuant to this Section 6.10.

SECTION 6.11.  UNDERTAKING FOR COSTS.

               In any suit for the enforcement of any right or remedy under 
this Indenture or in any suit against the Trustee for any action taken or 
omitted by it as a Trustee, a court in its discretion may require the filing 
by any party, litigant in the suit of an undertaking to pay the costs of the 
suit, and the court in its discretion may assess reasonable costs, including 
reasonable attorneys' fees, against any 


                                   51



party litigant in the suit, having due regard to the merits and good faith of 
the claims or defenses made by the party litigant. This Section does not 
apply to a suit by the Trustee, a suit by a Holder of a Senior Note pursuant 
to Section 6.07 hereof, or a suit by Holders of more than 10% in principal 
amount of the then outstanding Senior Notes.

                           ARTICLE 7
                            TRUSTEE

SECTION 7.01.   DUTIES OF TRUSTEE.

               (a)  If an Event of Default has occurred and is continuing, 
the Trustee shall exercise such of the rights and powers vested in it by this 
Indenture, and use the same degree of care and skill in its exercise, as a 
prudent man would exercise or use under the circumstances in the conduct of 
his own affairs.

               (b)  Except during the occurrence and continuance of an Event of
        Default:

               (i)  the Trustee need perform only those duties that are 
        specifically set forth in this Indenture and any Supplemental 
        Indenture; and

               (ii) in the absence of bad faith on its part, the Trustee may
        conclusively rely, as to the truth of the statements and the correctness
        of the opinions expressed therein, upon certificates or opinions 
        furnished to the Trustee and conforming to the requirements of this 
        Indenture.  However, the Trustee shall examine the certificates and 
        opinions to determine whether or not they conform to the requirements 
        of this Indenture.

               (c)  The Trustee may not be relieved from liabilities for its 
         own negligent action, its own negligent failure to act, or its own 
         willful misconduct, except that:

               (i)  this paragraph does not limit the effect of paragraph (b) 
         of this Section 7.01;

               (ii) the Trustee shall not be liable for any error of judgment 
         made in good faith by a Responsible Officer, unless it is proved 
         that the Trustee was negligent in ascertaining the pertinent facts; 
         and

               (iii) the Trustee shall not be liable with respect to any 
         action it takes or omits to take in good faith in accordance with a 
         direction received by it pursuant to Section 6.05 hereof.


                                         52



               (d)  Whether or not therein expressly so provided, every 
         provision of this Indenture that in any way relates to the Trustee 
         is subject to paragraphs (a), (b), and (c) of this Section 7.01 and 
         the requirements of the TIA.

               (e)  No provision of this Indenture shall require the Trustee 
         to expend or risk its own funds or incur any liability.  The Trustee 
         may refuse to perform any duty or exercise any right or power unless 
         it receives indemnity satisfactory to it against any loss, liability 
         or expense.

               (f)  The Trustee shall not be liable for interest on any money 
         received by it except as the Trustee may agree in writing with the 
         Company. Money held in trust by the Trustee need not be segregated 
         from other funds except to the extent required by law.

SECTION 7.02.   RIGHTS OF TRUSTEE.

               (a)  The Trustee may conclusively rely upon any document (and 
         any facts or matters stated in any document) believed by it to be 
         genuine and to have been signed or presented by the proper Person.  
         The Trustee need not investigate any fact or matter stated in the 
         document.

               (b)  Before the Trustee acts or refrains from acting, it may 
         require an Officers' Certificate or an Opinion of Counsel or both.  
         The Trustee shall not be liable for any action it takes or omits to 
         take in good faith in reliance on such Officers' Certificate or 
         Opinion of Counsel.  The Trustee may consult with counsel and the 
         written advice of such counsel or any Opinion of Counsel shall be 
         full and complete authorization and protection from liability in 
         respect of any action taken, suffered or omitted by it hereunder in 
         good faith and in reliance thereon.

               (c)  The Trustee may act through its agents and shall not be 
         responsible for the misconduct or negligence of any agent appointed 
         with due care.

               (d)  The Trustee shall not be liable for any action it takes 
         or omits to take in good faith that it believes to be authorized or 
         within the rights or powers conferred upon it by this Indenture.

               (e)  Unless otherwise specifically provided in this Indenture, 
         any demand, request, direction or notice from the Company shall be 
         sufficient if signed by an Officer of the Company.

               (f)  The Trustee shall be under no obligation to exercise any 
         of the rights or powers vested in it by this Indenture at the 
         request or direction of the Holders unless such Holders shall have 
         offered to the Trustee security or indemnity reasonably satisfactory 
         to the Trustee against the costs, expenses and liabilities that 
         might be incurred by it in compliance with such request or direction.

               (g)  The Trustee shall not be required to expend or risk its 
         own funds or otherwise incur any financial liability in the 
         performance of any of its duties hereunder, or in the exercise of 
         any 


                                       53



         of its rights or powers, if it shall have reasonable grounds for 
         believing that repayment of such funds or adequate indemnity against 
         such risk or liability is not assured to it.

               (h)  The Trustee shall have no duty to inquire as to the 
         performance of the Company's covenants in Article 4 hereof.  In 
         addition, the Trustee shall not be deemed to have knowledge of any 
         Default or Event of Default except (i) any Event of Default 
         occurring pursuant to Sections 6.01(i) or 6.01(ii) hereof; or (ii) 
         any Default or Event of Default of which the Trustee shall have 
         received written notification or obtained actual knowledge.

SECTION 7.03.   INDIVIDUAL RIGHTS OF TRUSTEE.

               The Trustee in its individual or any other capacity may become 
the owner or pledgee of Senior Notes and may otherwise deal with the Company 
or any Affiliate of the Company with the same rights it would have if it were 
not Trustee.  However, in the event that the Trustee acquires any conflicting 
interest it must eliminate such conflict within 90 days, apply to the SEC for 
permission to continue as trustee or resign.  Any Agent may do the same with 
like rights and duties.  The Trustee is also subject to Sections 7.10 and 
7.11 hereof.

SECTION 7.04.   TRUSTEE'S DISCLAIMER.

               The Trustee makes no representation as to the validity or 
adequacy of this Indenture or the Senior Notes, it shall not be accountable 
for the Company's use of the proceeds from the Senior Notes or any money paid 
to the Company or upon the Company's direction under any provision of this 
Indenture, it shall not be responsible for the use or application of any 
money received by any Paying Agent other than the Trustee, and it shall not 
be responsible for any statement or recital in this Indenture or any 
statement in the Senior Notes or any other document in connection with the 
sale of the Senior Notes or pursuant to this Indenture other than its 
certificate of authentication.

SECTION 7.05.   NOTICE OF DEFAULTS.

               If a Default or Event of Default occurs and is continuing and 
if it is known to the Trustee, the Trustee shall mail to Holders of Senior 
Notes a notice of the Default or Event of Default within 90 days after it 
occurs, unless such Default or Event of Default shall have been cured.  
Except in the case of a Default or Event of Default in payment of principal 
of, or premium, if any, or interest on any Senior Note, the Trustee may 
withhold the notice if and so long as a committee of its Responsible Officers 
in good faith determines that withholding the notice is in the interests of 
the Holders of the Senior Notes.


                                    54



SECTION 7.06.   REPORTS BY TRUSTEE TO HOLDERS OF THE SENIOR NOTES.

               Within 60 days after each May 15 beginning with the May 15 
following the date hereof, and for so long as Senior Notes remain 
outstanding, the Trustee shall mail to the Holders of  the Senior Notes a 
brief report dated as of such reporting date that complies with TIA Section 
313(a) (but if the event described in Section 313(a) of the TIA has occurred 
within twelve months preceding the reporting date, no report need be 
transmitted).  The Trustee also shall comply with TIA Section 313(b)(2).  The 
Trustee shall also transmit by mail all reports as required by TIA Section 
313(c).

               Commencing at the time this Indenture is qualified under the 
TIA, a copy of each report at the time of its mailing to the Holders of 
Senior Notes shall be mailed to the Company and filed with the SEC and each 
stock exchange on which the Senior Notes are listed in accordance with TIA 
Section 313(d).  The Company shall promptly notify the Trustee when the 
Senior Notes are listed on any stock exchange.

SECTION 7.07.   COMPENSATION AND INDEMNITY.

               The Company shall pay to the Trustee from time to time 
reasonable compensation for its acceptance of this Indenture and services 
hereunder.  The Trustee's compensation shall not be limited by any law on 
compensation of a trustee of an express trust.  The Company shall reimburse 
the Trustee upon request for all reasonable disbursements, advances and 
expenses incurred by it or made by it in addition to the compensation for its 
services, including reasonable compensation and the expenses and 
disbursements of its agents and counsel.  Such expenses shall include the 
reasonable compensation, disbursements and expenses of the Trustee's agents 
and counsel, whether incurred in disputes between the parties or disputes 
with third parties or otherwise. 

               The Company shall indemnify the Trustee against any loss, 
liability or expense incurred by it arising out of or in connection with the 
acceptance or administration of its duties under this Indenture, except as 
set forth in the next paragraphs, including the costs and expenses of 
enforcing this Indenture against the Company (including this Section 7.07) 
and defending itself against any claim (whether asserted by the Company, any 
Holder or any other Person). The Trustee shall notify the Company promptly of 
any claim for which it may seek indemnity.  Failure by the Trustee to so 
notify the Company shall not relieve the Company or any Person of any 
liability or obligations hereunder.  The Company shall defend the claim and 
the Trustee shall cooperate in the defense. The Trustee may have separate 
counsel and the Company shall pay the reasonable fees and expenses of such 
counsel.            

               The Company need not reimburse any expense or indemnify 
against any loss or liability attributed solely to the Trustee's negligence 
or bad faith.


                                      55



               To secure the Company's payment obligations in this Section 
7.07, the Trustee shall have a Lien prior to the Senior Notes on all money or 
property held or collected by the Trustee,  except that held in trust to pay 
principal and interest on particular Senior Notes.  Such Lien shall survive 
the satisfaction and discharge of this Indenture.

               When the Trustee incurs expenses or renders services after an 
Event of Default specified in Section 6.01(vii) or (viii) hereof occurs, the 
expenses and the compensation for the services (including the fees and 
expenses of its agents and counsel) are intended to constitute expenses of 
administration under any Bankruptcy Law.

SECTION 7.08.   REPLACEMENT OF TRUSTEE.

               A resignation or removal of the Trustee and appointment of a 
successor Trustee shall become effective only upon the successor Trustee's 
acceptance of appointment as provided in this Section 7.08.

               The Trustee may resign and be discharged from the trust hereby 
created by so notifying the Company.  The Holders of a majority in principal 
amount of the then outstanding Senior Notes may remove the Trustee by so 
notifying the Trustee and the Company in writing.  The Company may remove the 
Trustee if:

          (a)  the Trustee fails to comply with Section 7.10 hereof;

          (b)  the Trustee is adjudged a bankrupt or an insolvent or an order
     for relief is entered with respect to the Trustee under any Bankruptcy 
     Law;

          (c)  a Custodian or public officer takes charge of the Trustee or its
     property; or

          (d)  the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the 
office of Trustee for any reason, the Company shall promptly appoint a 
successor Trustee.  Within one year after the successor Trustee takes office, 
the Holders of a majority in principal amount of the then outstanding Senior 
Notes may appoint a successor Trustee to replace the successor Trustee 
appointed by the Company.

          If a successor Trustee does not take office within 60 days after 
the retiring Trustee resigns or is removed, the retiring Trustee, the 
Company, or the Holders of at least 10% in principal amount (or principal 
amount at maturity, as the case may be) of the then outstanding Senior Notes 
may petition any court of competent jurisdiction for the appointment of a 
successor Trustee.


                                       56



               If the Trustee, after written request by any Holder of a 
Senior Note who has been a Holder of a Senior Note for at least six months, 
fails to comply with Section 7. 10, such Holder of a Senior Note may petition 
any court of competent jurisdiction for the removal of the Trustee and the 
appointment of a successor Trustee.

               A successor Trustee shall deliver a written acceptance of its 
appointment to the retiring Trustee and to the Company.  Thereupon, the 
resignation or removal of the retiring Trustee shall become effective, and 
the successor Trustee shall have all the rights, powers and duties of the 
Trustee under this Indenture.  The successor Trustee shall mail a notice of 
its succession to Holders of the Senior Notes.  The retiring Trustee shall 
promptly transfer all property held by it as Trustee to the successor 
Trustee, subject to the Lien provided for in Section 7.07 hereof.  
Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the 
Company's obligations under Section 7.07 hereof shall continue for the 
benefit of the retiring Trustee.

SECTION 7.09.   SUCCESSOR TRUSTEE BY MERGER, ETC.

               If the Trustee consolidates, merges or converts into, or 
transfers all or substantially all of its corporate trust business to, 
another corporation, the successor corporation without any further act shall 
be the successor Trustee.

SECTION 7.10.  ELIGIBILITY, DISQUALIFICATION.

               The final paragraph of this Section shall not be operative as 
a part of this Indenture until this Indenture is qualified under the TIA and 
until such qualification this Indenture shall be construed as if said 
paragraph were not contained herein.

               There shall at all times be a Trustee hereunder that is a 
corporation organized and doing business under the laws of the United States 
of America or of any state thereof that is authorized under such laws to 
exercise corporate trustee power, that is subject to supervision or 
examination by federal or state authorities and that has a combined capital 
and surplus of at least $50 million as set forth in its most recent published 
annual report of condition.

               This Indenture shall always have a Trustee who satisfies the 
requirements of TIA Section 310(a)(1), (2) and (5).  The Trustee is subject 
to TIA Section 310(b).

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

               The Trustee is subject to TIA Section 311(a), excluding any 
creditor relationship listed in TIA Section 311 (b).  A Trustee that has 
resigned or been removed shall be subject to TIA Section 311(a) to the extent 
indicated therein.


                                      57



                                     ARTICLE 8
                      LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01.   OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

               The Company may, at the option of its Board of Directors 
evidenced by a resolution set forth in an Officers' Certificate, at any time, 
elect to have either Section 8.02 or 8.03 hereof be applied to all 
outstanding Senior Notes of any series upon compliance with the conditions 
set forth below in this Article Eight.

SECTION 8.02.    LEGAL DEFEASANCE AND DISCHARGE.

               Upon the Company's exercise under Section 8.01 hereof of the 
option applicable to this Section 8.02, the Company shall, subject to the 
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to 
have been discharged from its obligations with respect to all outstanding 
Senior Notes of any series on the date the conditions set forth below are 
satisfied (hereinafter, "LEGAL DEFEASANCE").  For this purpose, Legal 
Defeasance means that the Company shall be deemed to have paid and discharged 
the entire Indebtedness represented by the outstanding Senior Notes of such 
series, which shall thereafter be deemed to be " outstanding" only for the 
purposes of Section 8.05 hereof and the other Sections of this Indenture 
referred to in (a) and (b) below, and to have satisfied all its other 
obligations under such Senior Notes and this Indenture (and the Trustee, on 
demand of and at the expense of the Company, shall execute proper instruments 
acknowledging the same), except for the following provisions which shall 
survive until otherwise terminated or discharged hereunder: (a) the rights of 
Holders of outstanding Senior Notes of such series to receive solely from the 
trust fund described in Section 8.04 hereof, and as more fully set forth in 
such Section, payments in respect of the principal of, and premium, if any, 
and interest on such Senior Notes when such payments are due from the funds 
held by the Trustee in the trust, (b) the Company's obligations with respect 
to such Senior Notes of such series under Sections 2.06, 2.08, 2.09, 2.12 and 
4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the 
Trustee under this Indenture and the Company's obligations in connection 
therewith and (d) the obligations of the Company under this Article Eight.  
Subject to compliance with this Article Eight, the Company may exercise its 
option under this Section 8.02 notwithstanding the prior exercise of its 
option under Section 8.03 hereof.

SECTION 8.03.   COVENANT DEFEASANCE.

               Upon the Company's exercise under Section 8.01 hereof of the 
option applicable to this Section 8.03, the Company shall, subject to the 
satisfaction of the conditions set forth in Section 8.04 hereof, be released 
from its obligations under the covenants contained in Sections 4.07, 4.08, 
4.09, 4.10, 4.11, 4.12, 4.14 and Article 5 hereof with respect to the 
outstanding Senior Notes of any series on and after the date the conditions 
set forth below are satisfied (hereinafter, "COVENANT DEFEASANCE"), and such 
Senior Notes shall thereafter be deemed not "outstanding" for the purposes of 
any direction,


                                 58



waiver, consent or declaration or act of Holders (and the 
consequences of any thereof) in connection with such covenants, but shall 
continue to be deemed "outstanding" for all other purposes hereunder (it 
being understood that such Senior Notes shall not be deemed outstanding for 
accounting purposes).  For this purpose, Covenant Defeasance means that, with 
respect to the outstanding Senior Notes of such series, the Company may omit 
to comply with and shall have no liability in respect of any term, condition 
or limitation set forth in any such covenant, whether directly or indirectly, 
by reason of any reference elsewhere herein to any such covenant or by reason 
of any reference in any such covenant to any other provision herein or in any 
other document and such omission to comply shall not constitute a Default or 
an Event of Default under Section 6.01 hereof, but, except as specified 
above, the remainder of this Indenture and such Senior Notes of such series 
shall be unaffected thereby.  In addition, upon the Company's exercise under 
Section 8.01 hereof of the option applicable to this Section 8.03 hereof, 
subject to the satisfaction of the conditions set forth in Section 8.04 
hereof, Sections 6.01(iii) through 6.01(vii) hereof shall not constitute 
Events of Default.

SECTION 8.04.   CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

               The following shall be the conditions to the application of 
either Section 8.02 or 8.03 hereof to the outstanding Senior Notes:

     nationally recognized in the United States, to pay the principal of, 
     premium, if any, and interest on the outstanding Senior Notes on the stated
     date for payment thereof or on the applicable redemption date of such 
     Senior Notes, and the Company must specify whether the Senior Notes are 
     being defeased to maturity or to a particular redemption date;

     Service a ruling or (B) since the date hereof, there has been a change in 
     the applicable federal income tax law, in either case to the effect that, 
     and based thereon such Opinion of Counsel shall confirm that, the Holders 
     of the outstanding Senior Notes will not recognize income, gain or loss 
     for federal income tax purposes as a result of such Legal Defeasance and 
     will be subject to federal income tax on the same amounts, in the same 
     manner and at the same times as would have been the case if such Legal 
     Defeasance had not occurred;

               (c)  in the case of an election under Section 8.03 hereof, the 
     Company shall have delivered to the Trustee an Opinion of Counsel

     income, gain or loss for federal income tax purposes as a result of
     such Covenant Defeasance and will be subject to federal income tax

     occurred;

          (d)  the Company shall covenant that no Default or Event of Default
     shall have occurred and be continuing on the date of such deposit (other
     than a Default or Event of Default resulting from the incurrence of
     Indebtedness all or a portion of the proceeds of which will be used to
     defease the Senior Notes pursuant to this Article Eight concurrently with
     such incurrence) or insofar as Sections 6.01(vii) and (viii) hereof are
     concerned, at any time in the period ending on the 91st day after the date
     of deposit;

          (e)  the Company shall covenant that such Legal Defeasance or Covenant
     Defeasance shall not result in a breach or violation of, or constitute a
     default under, any material agreement or instrument (other than this
     Indenture) to which the Company or any of its Subsidiaries are parties or
     by which the Company or any of its Subsidiaries are bound;

          (f)  the Company shall have delivered to the Trustee an Officers'

     of the Company or with the intent of defeating, hindering, delaying or
     defrauding any other creditors of the Company; and

          (g)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for, in the case of the Officers' Certificate, clauses

     (c) and (e), have been complied with.


SECTION 8.05.  DEPOSITED MONEY AND GOVERNMENT SENIOR NOTES TO BE HELD IN TRUST;
               OTHER MISCELLANEOUS PROVISIONS.

          Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other

provisions of such Senior Notes and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as Paying

Holders of such Senior Notes of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need
not be segregated from other funds except to the extent required by law.


          The Company shall pay and indemnify the Trustee against any tax, 
fee or other charge imposed on or assessed against the cash or Government 
Securities deposited pursuant to Section 8.04 hereof or the principal and 
interest received in respect thereof other than any such tax, fee or other 
charge which by law is for the account of the Holders of the outstanding 
Senior Notes.

          Anything in this Article Eight to the contrary notwithstanding, the 
Trustee shall deliver or pay to the Company from time to time upon the 
request of the Company any money or non-callable Government Securities held 
by it as provided in Section 8.04 hereof which, in the opinion of a 
nationally recognized firm of independent public accountants expressed in a 
written certification thereof delivered to the Trustee (which may be the 
opinion delivered under Section 8.04(a) hereof), are in excess of the amount 
thereof that would then be required to be deposited to effect an equivalent 
Legal Defeasance or Covenant Defeasance.

SECTION 8.06.   REPAYMENT OF COMPANY.

          Any money deposited with the Trustee or any Paying Agent, or then 
held by the Company, in trust for the payment of the principal of, or 
premium, if any, or interest on any Senior Note and remaining unclaimed for 
two years after such principal, and premium, if any, or interest has become 
due and payable shall be paid to the Company on its request or (if then held 
by the Company) shall be discharged from such trust; and the Holder of such 
Senior Note shall thereafter, as a secured creditor, look only to the Company 
for payment thereof, and all liability of the Trustee or such Paying Agent 
with respect to such trust money, and all liability of the Company as trustee 
thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such 
Paying Agent, before being required to make any such repayment, may at the 
expense of the Company cause to be published once, in the New York Times and 
The Wall Street Journal (national edition), notice that such money remains 
unclaimed and that, after a date specified therein, which shall not be less 
than 30 days from the date of such notification or publication, any unclaimed 
balance of such money then remaining will be repaid to the Company.

SECTION 8.07.   REINSTATEMENT.

          If the Trustee or Paying Agent is unable to apply any Dollars or 
Government Securities in accordance with Section 8.02 or 8.03 hereof, as the 
case may be, by reason of any order or judgment of any court or governmental 
authority enjoining, restraining or otherwise prohibiting such application, 
then the Company's obligations under this Indenture and the Senior Notes 
shall be revived and reinstated as though no deposit had occurred pursuant to 
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is 
permitted to apply all such money in accordance with Section 8.02

                                       - 61 -



or 8.03 hereof, as the case may be; PROVIDED, HOWEVER, that, if the Company 
make any payment of principal of, premium, if any, or interest on any Senior 
Note following the reinstatement of its obligations, the Company shall be 
subrogated to the rights of the Holders of such Senior Notes to receive such 
payment from the money held by the Trustee or Paying Agent.

into Supplemental Indentures hereto which shall thereafter form a part 
hereof, without the consent of any Holder of a Senior Note, for any one or

addition to the Initial Series Senior Notes) and to specify certain terms of 
such series of Senior Notes, which terms may include, but are not limited to, 
those set forth in Section 2.01, all in a manner not inconsistent with the 
provisions of this Indenture;

          (d)  to provide that the Company shall not issue any additional 
Senior Notes or to add conditions, limitations and restrictions on the 
Company with respect to any series of Senior Notes under this Indenture;

          (e)  to add additional covenants and agreements of the Company to 
this Indenture, or to add to the Events of Default specified in Section 6.01

                                                S&A DRAFT -JUNE 10, 1998

          (g)  to provide for the assumption of the Company's obligations to 
the Holders of the Senior Notes in the case of a merger, amalgamation, 
consolidation or sale of all or substantially all of the assets pursuant to 
Article Five hereof;

          (h)  to make any change that would provide any additional rights or 
benefits to the Holders of the Senior Notes or that does not adversely affect 
the legal rights hereunder of any Holder of the Senior Notes;

          (i)  to comply with requirements of the SEC in order to effect or 
maintain the qualification of this Indenture under the TIA.

          Upon the request of the Company accompanied by a resolution of its 
Board of Directors authorizing the execution of any such amended or 
Supplemental Indenture, and upon receipt by the Trustee of the documents 
described in Section 7.02 hereof, the Trustee shall join with the Company in 
the execution of any amended or Supplemental Indenture authorized or 
permitted by the terms of this Indenture and to make any further appropriate 
agreements and stipulations that may be therein contained, but the Trustee 
shall not be obligated to enter into such amended or supplemental Indenture 
that affects its own rights, duties or immunities under this Indenture or 
otherwise.

SECTION 9.02.   WITH CONSENT OF HOLDERS OF SENIOR NOTES.

          Except as provided below in this Section 9.02, the Company and the 
Trustee may amend or supplement this Indenture, and the Senior Notes, and 
enter into Supplemental Indentures hereto which shall thereafter form a part 
hereof, with the consent of the Holders of at least a majority in principal 
amount (or principal amount at maturity, as the case may be) of the Senior 
Notes then outstanding (including, without limitation, consents obtained in 
connection with a purchase of, or tender offer or exchange offer for, Senior 
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default 
or Event of Default (other than a Default or Event of Default in the payment 
of the principal of, or interest on, the Senior Notes, except a payment 
default resulting from an acceleration that has been rescinded) or compliance 
with any provision of this Indenture or the Senior Notes may be waived with 
the consent of the Holders of a majority in principal amount (or principal 
amount at maturity, as the case may be) of the then outstanding Senior Notes 
(including consents obtained in connection with a tender offer or exchange 
offer for the Senior Notes); PROVIDED, HOWEVER, that if there shall be Senior 
Notes of more than one series outstanding and if the proposed action to be 
taken will materially adversely affect the rights of holders of Senior Notes 
of one or more of such series, then the consent (including consents obtained 
in connection with a tender offer or exchange offer for Senior Notes) only of 
holders of a majority in aggregate principal amount (or principal amount at 
maturity, as the case may be) of outstanding Senior Notes of all series so 
affected, considered as one class, shall be required.

                                       - 63 -




          Upon the request of the Company accompanied by a resolution of its 
Board of Directors authorizing the execution of any such amended or 
Supplemental Indenture, and upon the filing with the Trustee of evidence 
satisfactory to the Trustee of the consent of the Holders of Senior Notes as 
aforesaid, and upon receipt by the Trustee of the documents described in 
Section 7.02 hereof, the Trustee shall join with the Company in the execution 
of such amended or Supplemental Indenture unless such amended or Supplemental 
Indenture affects the Trustee's own rights, duties or immunities under this 
Indenture or otherwise, in which case the Trustee may in its discretion, but 
shall not be obligated to, enter into such amended or Supplemental Indenture.

          It shall not be necessary for the consent of the Holders of Senior 
Notes under this Section 9.02 to approve the particular form of any proposed 
amendment or waiver, but it shall be sufficient if such consent approves the 
substance thereof.

          After an amendment, supplement or waiver under this Section becomes 
effective, the Company shall mail to the Holders of Senior Notes affected 
thereby a notice briefly describing the amendment, supplement or waiver.  Any 
failure of the Company to mail such notice, or any defect therein, shall not, 
however, in any way impair or affect the validity of any such amended or 
Supplemental Indenture or waiver.  Subject to Sections 6.04 and 6.07 hereof, 
the Holders of a majority in aggregate principal amount of the Senior Notes 
then outstanding may waive compliance in a particular instance by the Company 
with any provision of this Indenture, the Senior Notes or any Supplemental 
Indenture. Subject to Section 9.01(a)(i), however, without the consent of 
each Holder affected, an amendment, waiver or Supplemental Indenture may not 
(with respect to any Senior Notes held by a non-consenting Holder):

          (a)  reduce the principal amount (or principal amount at maturity,
     as the case may be) of Senior Notes whose Holders must consent to an
     amendment, supplement or waiver;

          (b)  reduce the principal of or change the fixed maturity of any
     Senior Note or alter or waive any of the provisions with respect to the
     redemption of the Senior Notes except as provided above with respect to
     Sections 3.09, 4.10 and 4.14 hereof;

          (c)  reduce the rate of or change the time for payment of interest on
     any Senior Note;

          (d)  after the obligation has arisen for the Company to make an offer
     to purchase following the occurrence of a Change of Control or Sale of
     Assets, alter the obligation to purchase the Senior Notes in accordance
     with such offer to purchase or waive any default in the performance
     thereof;

                                       - 64-




          (e)  waive a Default or Event of Default in the payment of principal
     of, or interest on, the Senior Notes (except a rescission of acceleration
     of the Senior Notes by the Holders of at least a majority in aggregate
     principal amount (or principal amount at maturity, as the case may be) of
     the then outstanding Senior Notes and a waiver of the payment default that
     resulted from such acceleration);

          (f)  make any Senior Note payable in money other than that stated in
     the Senior Notes;

          (g)  make any change in the provisions of this Indenture regarding
     waivers of past Defaults or the rights of Holders of Senior Notes to
     receive payments of principal of, or interest on, the Senior Notes;

          (h)  waive a redemption payment with respect to any Senior Note (other
     than a payment required by Sections 4.10 or 4.14 hereof); or

          (i)  make any change in the foregoing amendment and waiver provisions.

SECTION 9.03.    COMPLIANCE WITH TRUST INDENTURE ACT.

           Every amendment or supplement to this Indenture or the Senior Notes
shall be set forth in an amended or Supplemental Indenture that complies with
the TIA in effect as of the date of amendment or supplement.

SECTION 9.04.    REVOCATION AND EFFECT OF CONSENTS.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Senior Note is a continuing consent by the Holder of a
Senior Note and every subsequent Holder of a Senior Note or portion of a Senior
Note that evidences the same debt as the consenting Holder's Senior Note, even
if notation of the consent is not made on any Senior Note.  However, any such
Holder of a Senior Note or subsequent Holder of a Senior Note may revoke the
consent as to its Senior Note if the Trustee receives written notice of
revocation before the date the waiver, Supplemental Indenture or amendment
becomes effective.  An amendment, Supplemental Indenture or waiver becomes
effective in accordance with its terms and thereafter binds every Holder.

          The Company may fix a record date for determining which Holders of
Senior Notes must consent to such Supplemental Indenture, amendment or waiver. 
If the Company fixes a record date, the record date shall be fixed at (i) the
later of 30 days prior to the first solicitation of such consent or the date of
the most recent list of Holders of Senior Notes furnished to the Trustee prior
to such solicitation pursuant to Section 2.07, or (ii) such other date as the
Company shall designate.

                                       - 65 -




SECTION 9.05.    NOTATION ON OR EXCHANGE OF SENIOR NOTES.

          The Trustee may place an appropriate notation about an amendment, 
Supplemental Indenture or waiver on any Senior Note thereafter authenticated. 
The Company in exchange for all Senior Notes may issue and the Trustee shall 
authenticate new Senior Notes that reflect the amendment, Supplemental 
Indenture or waiver.

          Failure to make the appropriate notation or issue a new Senior Note
shall not affect the validity and effect of such amendment, Supplemental
Indenture or waiver.

SECTION 9.06.   TRUSTEE TO SIGN AMENDMENTS, ETC.

          The Trustee shall sign any amended or Supplemental Indenture 
authorized pursuant to this Article Nine if the amendment or supplement does 
not adversely affect the rights, duties, liabilities or immunities of the 
Trustee. The Company may not sign an amendment or Supplemental Indenture 
until its Board of Directors approves it.  In executing any amended or 
supplemental indenture, the Trustee shall be entitled to receive, and shall 
be fully protected in relying upon, an Officer's Certificate and an Opinion 
of Counsel stating that the execution of such amended or Supplemental 
Indenture is authorized or permitted by this Indenture and that all 
conditions precedent have been complied with.

SECTION 9.07.   EFFECT OF SUPPLEMENTAL INDENTURES.  

          Upon the execution of any Supplemental Indenture under this Article 
9 by the Trustee and the Company, this Indenture shall be and shall be deemed 
to be modified and amended in accordance therewith and such Supplemental 
Indenture shall be and shall be deemed to be a part of the terms and 
conditions of this Indenture for all purposes; and every Holder of Senior 
Notes theretofore or thereafter authenticated and delivered hereunder shall 
be bound thereby, except to the extent that the terms of such Supplemental 
Indenture relate solely to one or more particular series of Senior Notes 
identified therein.  In the event of any inconsistency between the Indenture 
and the terms of any Supplemental Indenture, the terms of such Supplemental 
Indenture shall control.

SECTION 10.01.  TRUST INDENTURE ACT CONTROLS.

          If any provision of this Indenture limits, qualifies or conflicts 
with the duties or rights imposed by TIA Section 318(c), the imposed duties 
or rights shall control.
