                                    THE NOTES

Section 2.01 Form and Dating.

      (a)   General. The Notes and the Trustee's certificate of authentication
will be substantially in the form of Exhibit A or Exhibit B, as applicable. The
Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage. Each Note will be dated the date of its authentication.
The Notes shall be in denominations of $ 1,000 and integral multiples thereof.

      The terms and provisions contained in the Notes will constitute, and are
hereby expressly made, a part of this Indenture and the Issuers and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby. However, to the extent any

                                       43

<PAGE>

provision of any Note conflicts with the express provisions of this Indenture,
the provisions of this Indenture shall govern and be controlling.

      (b)   Global Notes. Notes issued in global form will be substantially in
the form of Exhibit A or Exhibit B, as applicable (including the Global Note
Legend thereon and the "Schedule of Exchanges of Interests in the Global Note"
attached thereto). Notes issued in definitive form will be substantially in the
form of Exhibit A (but without the Global Note Legend thereon and without the
"Schedule of Exchanges of Interests in the Global Note" attached thereto). Each
Global Note will represent such of the outstanding Notes as will be specified
therein and each shall provide that it represents the aggregate principal amount
of outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time
be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Notes represented
thereby will be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required
by Section 2.06.

      (c)   Temporary Global Notes. Notes offered and sold in reliance on
Regulation S will be issued initially in the form of the Regulation S Temporary
Global Note, which will be deposited on behalf of the purchasers of the Notes
represented thereby with the Trustee, at its corporate trust office, as
Custodian, and registered in the name of the Depositary or the nominee of the
Depositary for the accounts of designated agents holding on behalf of Euroclear
or Clearstream, duly executed by the Issuers and authenticated by the Trustee as
hereinafter provided. The Restricted Period will be terminated upon the receipt
by the Trustee of (1) a written certificate from the Depositary, together with
copies of certificates from Euroclear and Clearstream, certifying that they have
received certification of non-United States beneficial ownership of 100% of the
aggregate principal amount of the Regulation S Temporary Global Note (except to
the extent of any beneficial owners thereof who acquired an interest therein
during the Restricted Period pursuant to another exemption from registration
under the Securities Act and who will take delivery of a beneficial ownership
interest in a 144A Global Note or an IAI Global Note bearing a Private Placement
Legend, all as contemplated by Section 2.06(b)), and (2) an Officer's
Certificate from the Company stating that such Restricted Period has ended.

      Following the termination of the Restricted Period, beneficial interests
in the Regulation S Temporary Global Note will be exchanged for beneficial
interests in Regulation S Permanent Global Notes pursuant to the Applicable
Procedures. Simultaneously with the authentication of Regulation S Permanent
Global Notes, the Trustee will, upon receipt of written directions, cancel the
Regulation S Temporary Global Note. The aggregate principal amount of the
Regulation S Temporary Global Note and the Regulation S Permanent Global Notes
may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depositary or its nominee, as the case may be, in
connection with transfers of interest as hereinafter provided.

      (d)   Euroclear and Clearstream Procedures Applicable. The provisions of
the "Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of Clearstream
Banking" and "Customer Handbook" of Clearstream will be applicable to transfers
of beneficial interests in the Regulation S Temporary Global Note and the
Regulation S Permanent Global Notes that are held by Participants through
Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

      One Officer of each Issuer must sign the Notes for the Issuers by manual
or facsimile signature.

                                       44

<PAGE>

      If an Officer whose signature is on a Note no longer holds that office at
the time a Note is authenticated, the Note will nevertheless be valid.

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

      The Trustee will, upon receipt of a written order of the Issuers signed by
one Officer of each Issuer (an "Authentication Order"), authenticate Notes for
original issue up to the aggregate principal amount stated in paragraph 4 of the
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed such amount except as provided in Section 2.07.

      The Trustee may appoint an authenticating agent acceptable to the Issuers
to authenticate Notes. An authenticating agent may authenticate 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 Holders or an Affiliate of the Issuers.

Section 2.03 Registrar and Paying Agent.

      The Company, on behalf of itself and CalGen Finance, will maintain an
office or agency where Notes may be presented for registration of transfer or
for exchange ("Registrar") and an office or agency where Notes may be presented
for payment ("Paying Agent"). The Registrar will keep a register of the Notes
and of their transfer and exchange. The Issuers 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 Issuers may change any Paying Agent or Registrar without
notice to any Holder. The Company will notify the Trustee in writing of the name
and address of any Agent not a party to this Indenture. If the Issuers fail to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such. The Company or any of its Subsidiaries may act as Paying
Agent or Registrar.

      The Issuers initially appoint The Depository Trust Company ("DTC") to act
as Depositary with respect to the Global Notes.

      The Issuers initially appoint the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

      The Issuers will require each Paying Agent other than the Trustee 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, interest or Special Interest, if any, on, the Notes, and
will notify the Trustee of any default by the Issuers 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 by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) will have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it will 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 will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

                                       45

<PAGE>

      The Trustee will 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 will 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 and the
Company shall otherwise comply with TIA Section 312(a).

Section 2.06 Transfer and Exchange.

      (a)   Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. A Global Note will be exchangeable by
the Issuers for Definitive Notes if:

            (1)   the Issuers deliver to the Trustee written notice from the
      Depositary that it is unwilling or unable to continue to act as Depositary
      or that it is no longer a clearing agency registered under the Exchange
      Act and, in either case, a successor Depositary is not appointed by the
      Issuers within 120 days after the date of such notice from the
      Depositary;

            (2)   the Issuers in their sole discretion determine that the Global
      Notes (in whole but not in part) should be exchanged for Definitive Notes
      and deliver a written notice to such effect to the Trustee; provided, that
      in no event shall the Regulation S Temporary Global Note be exchanged by
      the Issuers for Definitive Notes prior to (x) the expiration of the
      Restricted Period and (y) the receipt by the Registrar of any certificates
      required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

            (3)   there has occurred and is continuing a Default or Event of
      Default with respect to the Notes.

      Upon the occurrence of any of the preceding events in (1), (2) or (3)
above, Definitive Notes shall be issued in such names as the Depositary shall
instruct the Trustee in writing. Global Notes also may be exchanged or replaced,
in whole or in part, as provided in Sections 2.07 and 2.10. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10, shall be
authenticated and delivered in the form of, and shall be, a Global Note. A
Global Note may not be exchanged for another Note other than as provided in this
Section 2.06(a); however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.06(b), (c) or (f).

      (b)   Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes will be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes will be subject to restrictions on transfer comparable to those set
forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Notes also will require compliance with
either subparagraph (1) or (2) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

            (1)   Transfer of Beneficial Interests in the Same Global Note.
      Beneficial interests in any Restricted Global Note may be transferred to
      Persons who take delivery thereof in the form of a beneficial interest in
      the same Restricted Global Note in accordance with the transfer
      restrictions set forth in the Private Placement Legend; provided, however,
      that prior to the

                                       46

<PAGE>

      expiration of the Restricted Period, transfers of beneficial interests in
      the Regulation S Temporary Global Note may not be made to a U.S. Person or
      for the account or benefit of a U.S. Person (other than the Initial
      Purchaser). Beneficial interests in any Unrestricted Global Note may be
      transferred to Persons who take delivery thereof in the form of a
      beneficial interest in an Unrestricted Global Note. No written orders or
      instructions shall be required to be delivered to the Registrar to effect
      the transfers described in this Section 2.06(b)(1).

            (2)   All Other Transfers and Exchanges of Beneficial Interests in
      Global Notes. In connection with all transfers and exchanges of beneficial
      interests that are not subject to Section 2.06(b)(1) above, the transferor
      of such beneficial interest must deliver to the Registrar either:

                  (A)   both:

                        (i)   a written order from a Participant or an Indirect
                  Participant given to the Depositary in accordance with the
                  Applicable Procedures directing the Depositary to credit or
                  cause to be credited a beneficial interest in another Global
                  Note in an amount equal to the beneficial interest to be
                  transferred or exchanged; and

                        (ii)  instructions given in accordance with the
                  Applicable Procedures containing information regarding the
                  Participant account to be credited with such increase; or

                  (B)   both:

                        (i)   a written order from a Participant or an Indirect
                  Participant given to the Depositary in accordance with the
                  Applicable Procedures directing the Depositary to cause to be
                  issued a Definitive Note in an amount equal to the beneficial
                  interest to be transferred or exchanged; and

                        (ii)  instructions given by the Depositary to the
                  Registrar containing information regarding the Person in whose
                  name such Definitive Note shall be registered to effect the
                  transfer or exchange referred to in (1) above;

                  provided, that in no event shall Definitive Notes be issued
                  upon the transfer or exchange of beneficial interests in the
                  Regulation S Temporary Global Note prior to (A) the expiration
                  of the Restricted Period and (B) the receipt by the Registrar
                  of any certificates required pursuant to Rule 903 under the
                  Securities Act.

      Upon consummation of an Exchange Offer by the Company in accordance with
      Section 2.06(f) hereof, the requirements of this Section 2.06(b)(2) shall
      be deemed to have been satisfied upon receipt by the applicable exchange
      agent of (i) the instructions contained in the Letter of Transmittal
      delivered by the Holder of such beneficial interests in the Restricted
      Global Notes or (ii) the instructions contained in the agent's message
      received by such exchange agent through DTC's Automated Tender Offer
      Procedures, as applicable. Upon satisfaction of all of the requirements
      for transfer or exchange of beneficial interests in Global Notes contained
      in this Indenture and the Notes or otherwise applicable under the
      Securities Act, the Trustee shall adjust the principal amount of the
      relevant Global Note(s) pursuant to Section 2.06(h) hereof.

            (3)   Transfer of Beneficial Interests to Another Restricted Global
      Note. A beneficial interest in any Restricted Global Note may be

      holder thereof for a beneficial interest in an Unrestricted Global Note or
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in an Unrestricted Global Note if the exchange or
      transfer complies with the requirements of Section 2.06(b)(2) above and:

                  (A)   such exchange or transfer is effected pursuant to the
            Exchange Offer in accordance with the Registration Rights Agreement
            and the holder of the beneficial interest to be transferred, in the
            case of an exchange, or the transferee, in the case of a transfer,
            certifies in the applicable Letter of Transmittal that it is not (i)
            a Broker-Dealer, (ii) a Person participating in the distribution of

            (1)   one or more Unrestricted Global Notes in an aggregate
      principal amount equal to the principal amount of the beneficial interests

specifically stated otherwise in the applicable provisions of this Indenture.

            (1)   Private Placement Legend. Except as permitted by the paragraph
      immediately following the legend below, each Global Note and each

REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION
REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN
VIOLATION OF THE FOREGOING RESTRICTIONS."

            Notwithstanding the foregoing, any Global Note or Definitive Note
      issued pursuant to Subparagraphs (b)(4), (c)(3), (c)(4), (d)(2), (d)(3),
      (e)(2) or (e)(3) of this Section 2.06 (and all Notes issued in exchange
      therefor or substitution thereof) will not bear the Private Placement
      Legend.

            (2)   Global Note Legend. Each Global Note will bear a legend in
      substantially the following form:

"THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL

NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR

            (3)   Regulation S Temporary Global Note Legend. The Regulation S
      Temporary Global Note will bear a legend in substantially the following
      form:

"THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE
CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS
SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE
BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED
TO RECEIVE PAYMENT OF INTEREST HEREON."

      (h)   Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note will be returned to or
retained and canceled by the Trustee in accordance with Section 2.11. At any
time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note or for Definitive Notes,
the principal amount of Notes represented by such Global Note will be reduced
accordingly and an endorsement will be made on such Global Note by the Trustee
or by the Depositary at the direction of the Trustee to reflect such reduction;
and if the beneficial interest is being exchanged for or transferred to a Person
who will take delivery thereof in the form of a beneficial interest in another
Global Note, such other Global Note will be increased accordingly and an
endorsement will be made on such Global Note by the Trustee or by the Depositary
at the direction of the Trustee to reflect such increase.

      (i)   General Provisions Relating to Transfers and Exchanges.

            (1)   To permit registrations of transfers and exchanges, the
      Issuers will execute and the Trustee will authenticate Global Notes and
      Definitive Notes upon receipt of an Authentication Order in accordance
      with Section 2.02 or at the Registrar's request.

            (2)   No service charge will be made to a Holder of a Global Note
      or to a Holder of a Definitive Note for any registration of transfer or
      exchange, but the Issuers may require payment of a sum sufficient to cover
      any transfer tax or similar governmental charge payable in connection
      therewith (other than any such transfer taxes or similar governmental
      charge payable upon exchange or transfer pursuant to Sections
      2.10, 3.06, 3.09, 4.10, 4.15 and 9.05).

            (3)   The Registrar will not be required to register the transfer of
      or exchange any Note selected for redemption in whole or in part, except
      the unredeemed portion of any Note being redeemed in part.

            (4)   All Global Notes and Definitive Notes issued upon any
      registration of transfer or exchange of Global Notes or Definitive Notes
      will be the valid obligations of the Issuers, evidencing the same debt,
      and entitled to the same benefits under this Indenture, as the Global
      Notes or Definitive Notes surrendered upon such registration of transfer
      or exchange.

            (5)   The Issuers will not be required:

                                       57

<PAGE>

                  (A)   to issue, to register the transfer of or to exchange any
            Notes during a period beginning at the opening of business 15 days
            before the day of any selection of Notes for redemption under
            Section 3.02 and ending at the close of business on the day of
            selection;

                  (B)   to register the transfer of or to exchange any Note
            selected for redemption in whole or in part, except the unredeemed
            portion of any Note being redeemed in part; or

                  (C)   to register the transfer of or to exchange a Note
            between a record date and the next succeeding interest payment date.

            (6)   Prior to due presentment for the registration of a transfer of
      any Note, the Trustee, any Agent and the Issuers may deem and treat the
      Person in whose name any Note is registered as the absolute owner of such
      Note for the purpose of receiving payment of principal of and interest on
      such Note and for all other purposes, and none of the Trustee, any Agent,
      the Company or CalGen Finance shall be affected by notice to the contrary.

            (7)   The Trustee will authenticate Global Notes and Definitive
      Notes in accordance with the provisions of Section 2.02.

            (8)   All certifications, certificates and Opinions of Counsel
      required to be submitted to the Registrar pursuant to this Section 2.06 to
      effect a registration of transfer or exchange may be submitted by
      facsimile.

Section 2.07 Replacement Notes.

      If any mutilated Note is surrendered to the Trustee or the Issuers and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Issuers will issue and the Trustee, upon receipt of an
Authentication Order, will authenticate a replacement Note if the Trustee's
requirements hereunder are met. If required by the Trustee or either Issuer, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent
and any authenticating agent from any loss that any of them may suffer if a Note
is replaced. The Issuers may charge the applicable Holder for their expenses in
replacing a Note.

      Every replacement Note is an additional obligation of the Issuers and will
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

      The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions hereof, and those described in this Section as
not outstanding. Except as set forth in Section 2.09, a Note does not cease to
be outstanding because the Company or an Affiliate of the Company holds the
Note.

      If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected purchaser.

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

                                       58

<PAGE>

      If the Paying Agent (other than the Company, a Subsidiary of the Company
or an Affiliate of any thereof) holds, on a redemption date or maturity date,
money sufficient to pay Notes payable on that date, then on and after that date
such Notes will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.09 Treasury Notes.

      In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or Consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, will be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee will be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

      Until certificates representing Notes are ready for delivery, the Issuers
may prepare and the Trustee, upon receipt of an Authentication Order, will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of certificated Notes but may have variations that the Issuers consider
appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee
will authenticate definitive Notes in exchange for temporary Notes.

      Holders of temporary Notes will be entitled to all of the benefits of this
Indenture.

Section 2.11 Cancellation.

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

Section 2.12 Defaulted Interest.

      If the Company defaults in a payment of interest on the Notes, it will pay
the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01. The Company will notify the Trustee in writing of the
amount of defaulted interest proposed to be paid on each Note and the date of
the proposed payment. The Company will fix or cause to be fixed each such
special record date and payment date, provided, that no such special record date
may be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) will mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

Section 2.13 Same Day Settlement and Payment.

      The Issuers will make payments in respect of the Notes represented by the
Global Notes

                                       59

<PAGE>

(including principal, premium, if any, and interest and Special Interest, if
any) by wire transfer of immediately available funds to the accounts specified
by the Holder of the Global Note. The Issuers will make all payments of
principal, interest and premium and Special Interest, if any, with respect to
Definitive Notes by wire transfer of immediately available funds to the accounts
specified by the Holders of the Definitive Notes or, if no such account is
specified, by mailing a check to each such Holder's registered address.

      Because of time zone differences, the securities account of a Euroclear or
Clearstream participant purchasing an interest in a Global Note from a
Participant in DTC will be credited, and any such crediting will be reported to
the relevant Euroclear or Clearstream participant, during the securities
settlement processing day (which must be a business day for Euroclear and
Clearstream) immediately following the settlement date of DTC. DTC has advised
the Issuers that cash received in Euroclear or Clearstream as a result of sales
of interests in a Global Note by or through a Euroclear or Clearstream
participant to a Participant in DTC will be received with value on the
settlement date of DTC but will be available in the relevant Euroclear or
Clearstream cash account only as of the business day for Euroclear or
Clearstream following DTC's settlement date.

                                   ARTICLE 3.

      If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee will select Notes for redemption or
purchase on a pro rata basis except:

            (1)   if the Notes are listed on any national securities exchange,
      in compliance with the requirements of the principal national securities
      exchange on which the Notes are listed; or

            (2)   if otherwise required by law.

      In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased will be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption or
purchase date by the Trustee from the outstanding Notes not previously called
for redemption or purchase.

                                       60

<PAGE>

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

Section 3.03 Notice of Redemption.

      Subject to the provisions of Section 3,09, at least 30 days but not more
than 60 days before a redemption date, the Company will mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address, except that redemption notices may
be mailed more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture pursuant to Article 8 or 12 of this Indenture. Notices of
redemption may not be conditional.

      The notice will identify the Note(s) to he redeemed and will state:

            (1)   the redemption date;

            (2)   the redemption price;

            (3)   if any Note is to be redeemed in part only, the portion of the
      principal amount of such Note to be redeemed and that, after the
      redemption date upon surrender of such Note, a new Note or Notes in
      principal amount equal to the unredeemed portion will be issued upon
      cancellation of the original Note;

            (4)   the name and address of the Paying Agent;

      Paying Agent to collect the redemption price;

            (6)   that, unless the Issuers default in making such redemption
      payment, interest on Notes called for redemption ceases to accrue on and
      after the redemption date;

            (7)   the paragraph of the Notes and/or Section of this Indenture
      pursuant to which the Notes called for redemption are being redeemed; and

            (8)   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 Notes.

      At the Company's request, the Trustee will give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
has delivered to the Trustee, at least 45 days prior to the redemption date, an
Officer's 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.

                                       61

<PAGE>

      Once notice of redemption is mailed in accordance with Section 3.03, 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 or Purchase Price.

      Not less than one Business Day prior to the redemption or purchase price
date, the Issuers will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued interest and
Special Interest, if any, on all Notes to be redeemed or purchased on that date.

deposited with the Trustee or the Paying Agent by the Issuers in excess of the

interest and Special Interest, if any, on, all Notes to be redeemed or
purchased.

      If the Issuers comply with the provisions of the preceding paragraph, on
and after the redemption or purchase date, interest will cease to accrue on the
Notes or the portions of Notes called for redemption or purchase. If a Note is
redeemed or purchased 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. If any Note called for redemption or purchase is not so paid upon
surrender for redemption or purchase because of the failure of the Issuers to
comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption or purchase 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 Notes and in Section 4.01.

Section 3.06 Notes Redeemed or Purchased in Part.

      Upon surrender of a Note that is redeemed or purchased in part, the
Issuers will issue and, upon receipt of an Authentication Order, the Trustee
will authenticate for the Holder, at the expense of the Company, a new Note
equal in principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

            (1)   that the Asset Sale Offer is being made pursuant to this
      Section 3.09 and Section 4.10;

            (2)   the amount of Net Proceeds being offered to purchase Notes and
      other First Priority Lien Obligations (the "Offer Amount"), the purchase
      price and the date on which the purchase will be made (the "Purchase
      Date"), which date will be no earlier than 30 and no later than 60 days
      from the date the notice is mailed;

            (3)   that any Note not tendered or accepted for payment will
      continue to accrue interest;

            (4)   that, unless the Issuers default in making such payment, any
      Note accepted for payment pursuant to the Asset Sale Offer will cease to
      accrue interest after the Purchase Date;

            (5)   that Holders electing to have a Note purchased pursuant to an
      Asset Sale Offer may elect to have Notes purchased in integral multiples
      of $1,000 only;

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

            (7)   that Holders will be entitled to withdraw their election if
      the Company, the Depositary or the Paying Agent, as the case may be,
      receives, not later than two Business Days before the Purchase Date, a
      facsimile transmission or letter setting forth the name of the Holder, the
      principal amount of the Note the Holder delivered for purchase and a
      statement that such Holder is withdrawing his election to have such Note
      purchased;

            (8)   that, if the aggregate principal amount of Notes and other
      First Priority Lien Obligations tendered in the Asset Sale Offer (or
      required to be purchased, prepaid or redeemed) exceeds the Offer Amount,
      the Company will select the Notes and other First Priority Lien
      Obligations to be purchased, prepaid or redeemed on a pro rota basis based
      on the principal amount of Notes and such other First Priority Lien
      Obligations tendered (or required to be

                                       63

      purchased, prepaid or redeemed), with such adjustments as may be deemed
      appropriate by the Company so that only Notes in denominations of $1,000,
      or integral multiples thereof, will be purchased, prepaid or redeemed; and

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

      On or before the Purchase Date, the Issuers will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer

tendered pursuant to the Asset Sale Offer (or required to be purchased, prepaid
or redeemed), or if less than the Offer Amount has been tendered (or is required
to be purchased, prepaid or redeemed), all Notes and other First Priority Lien
Obligations tendered (or required to be purchased, prepaid or redeemed), and
will deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officer's Certificate stating that such Notes or portions
thereof were accepted for payment by the Issuers in accordance with the terms of
this Section 3.09. Payment for any Notes so purchased will be made in the same
manner as interest payments are made. The Issuers, the Depositary or the Paying
Agent, as the case may be, will 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 Notes tendered by such Holder and accepted by
the Issuers for purchase, and the Issuers will promptly issue a new Note, and
the Trustee, upon written request from the Issuers, will authenticate and mail
or deliver (or cause to be transferred by book entry) such new Note to such
Holder, in a principal amount equal to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by
the Issuers to the Holder thereof. The Issuers will publicly announce the
results of the Asset Sale Offer on the Purchase Date.

      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 and
Special Interest, if any, will be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional
interest will be payable to Holders who tender Notes pursuant to the Asset Sale
Offer.

      The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
this Section 3.09 or Section 4.10, the Issuers will comply with the applicable
securities laws and regulations and will not be deemed to have breached their
obligations under this Section 3.09 or Section 4.10 by virtue of such
compliance.

      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.

Section 4.01 Payment of Notes.

      The Company will pay or cause to be paid the principal of, and premium, if
any, interest and Special Interest, if any, on, the Notes on the dates and in
the manner provided in the Notes. Principal, premium, if any, interest and
Special Interest, if any, will be considered paid on the date due if the Paying
Agent, if other than the Company or a Subsidiary thereof, 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

                                       64

to pay all principal, premium, if any, and interest and Special Interest, if
any, then due. The Company will pay all Special Interest, if any, in the same
manner on the dates and in the amounts set forth in the Registration Rights
Agreement.

      The Company will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the
extent lawful; it will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Special Interest (without regard to any applicable grace period) at the same
rate to the extent lawful.

Section 4.02 Maintenance of Office or Agency.

      The Company will 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 Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company will 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
fails to maintain any such required office or agency or fails 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 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 will in any manner relieve the Company of
its obligation to maintain an office or agency in the Borough of Manhattan, the
City of New York for such purposes. The Company will 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.

      The Company hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.03.

Section 4.03 Reports.

      Whether or not required by the rules and regulations of the SEC, so long
as any Notes are outstanding, the Company will furnish to the Holders or cause
the Trustee to furnish to the Holders, within the time periods specified in the
SEC's rules and regulations:

            (1)   all quarterly and annual reports that would be required to be
      filed with the SEC on Forms 10-Q and 10-K if the Company were required to
      file such reports; and

            (2)   all current reports that would be required to be filed with
      the SEC on Form 8-K if the Company were required to file such reports.

All such reports will be prepared in all material respects in accordance with
all of the rules and regulations applicable to such reports. Each annual report
on Form 10-K will include a report on the Company's consolidated financial
statements by the Company's certified independent accountants. In addition,
following consummation of the Exchange Offer contemplated by the Registration
Rights Agreement, the Company will file a copy of each of the reports referred
to in clauses (1) and (2) above with the SEC for public availability within the
time periods specified in the rules and regulations applicable to such reports
(unless the SEC will not accept such a filing or the Company has elected to pay

                                       65

<PAGE>

Special Interest in lieu of complying with the registration requirements of the
Registration Rights Agreement) and will post the reports on its website within
those time periods.

      If the Company is not subject to the periodic reporting requirements of
the Exchange Act for any reason, the Company will nevertheless file the reports
specified in the preceding paragraphs of this covenant with the SEC within the
time periods specified above unless the SEC will not accept such a filing or the
Company has elected to pay Special Interest in lieu of complying with the
registration requirements of the Registration Rights Agreement. However, if the
Company does not file any such reports with the SEC, the Company will post the
reports referred to in the preceding paragraphs on its website within the time
periods that would apply if the Company were required to file those reports with
the SEC.

      In addition, the Company and the Guarantors agree that, for so long as any
Notes remain outstanding, if at any time they are not required to file with the
SEC the reports required by the preceding paragraphs, they will furnish to the
Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

has been made under the supervision of the signing Officer with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture and the other Notes Documents, and further

her knowledge the Company has kept, observed, performed and fulfilled each and
every covenant contained in this Indenture and the other Notes Documents and is

and conditions of this Indenture or any other Note Document (or, if a Default or
Event of Default has 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 or interest or Special Interest, if any,

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 Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(1) 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 has violated
any provisions of Article 4 or Article 5 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)   So long as any of the Notes are outstanding, the Company will
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officer's Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

      The Company and each of the Guarantors covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, plead, or in any

or usury law wherever enacted, now or at any time hereafter in force, mat may
affect the covenants or the performance of this Indenture; and the Company and
each of the Guarantors (to the extent that it may lawfully do so) hereby

                  (C)   at the time of making any such Restricted Payment that
            is not a payment on or with respect to, or a purchase, redemption,
            defeasance or other acquisition of retirement for value of,
            Subordinated Indebtedness, all amounts then due under all

      being refinanced;

            (8)   Liens securing Indebtedness otherwise permitted to be incurred
      under the provisions of the covenant contained in Section 4.12 that limit

      pursuant to clause (3) of the definition of Permitted Debt; provided, that
      such encumbrance or restriction will not materially adversely affect the
      Company's ability to meet its obligations on the Notes when due, and, in
      the written opinion of the president, chief operating officer or chief
      financial officer of the Company, is required in order to obtain such
      Expansion Debt and is customary for financings of such type.

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Equity.

      The Company will not, and will not permit any of its Subsidiaries to,

            1.0, determined on a Pro Forma basis as if the Expansion Debt had
            been incurred at the beginning of such period and the proceeds
            therefrom had been applied as intended to be applied (but without
            giving effect to the completion of any construction projects unless

            to 1.0, determined on a Pro Forma basis as if the Expansion Debt had
            been incurred at the beginning of such period and the proceeds
            therefrom had been applied as intended to be applied (but without
            giving effect to the completion of any construction projects unless
            actual completion has been achieved),

                        (i)   at least 40% of the cost of such Expansion Assets
                  is financed with Equity Contributions or the proceeds of
                  Perpetual Preferred Stock or Affiliate Subordinated
                  Indebtedness, and

                        (ii)  after giving effect to such incurrence, the amount
                  of Expansion Debt incurred pursuant to this clause (3),
                  together with the aggregate amount of all other Expansion
                  Debt then outstanding, including all Permitted Refinancing
                  Indebtedness incurred to renew, refund, refinance, replace,
                  defease or discharge any Expansion Debt incurred pursuant to
                  this clause (3), does not exceed $250.0 million;

            (4)   the incurrence by the Company or any of its Subsidiaries of
      Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
      which are used to refund, refinance or replace, Indebtedness (other than
      intercompany Indebtedness) that was permitted by this Indenture to be
      incurred under clauses (2), (3), (4) or (10) of this paragraph;

            (5)   the incurrence by the Company or any Guarantor of intercompany
      Indebtedness between or among the Company and any Guarantor that is
      subordinated in right of payment to all Secured Obligations pursuant to a
      customary subordination agreement delivered to the Collateral Agent
      (together with all other documents or instruments required to effect such
      subordination and any other documents reasonably requested by the
      Collateral Agent in connection therewith), and is not secured other than
      by unperfected security interests; provided, however, that (i) any
      subsequent issuance or transfer of Equity Interests that results in any
      such Indebtedness being held by a Person other than the Company or a
      Guarantor and (ii) any sale or other transfer of any such Indebtedness to
      a Person that is not either the Company or a Guarantor will be deemed, in
      each case, to constitute an incurrence of such Indebtedness by the Company
      or such Guarantor, as the case may be, that was not permitted by this
      clause (5); and provided, further, that any such intercompany Indebtedness
      must be included in the Collateral;

            (6)   the incurrence by the Company or any of its Subsidiaries of
      Hedging Obligations, in connection with Permitted Debt or otherwise, in
      the ordinary course of business and not for speculative purposes;
      provided, that (a) such Hedging Obligations have tenors that expire on or
      prior to the maturity date (or other expiration) of the underlying
      obligation being hedged, and (b) any such Hedging Obligations hedging or
      managing interest rate risk with respect to (i) First Priority Lien Debt
      have tenors that expire on or prior to the Stated Maturity of the Notes,
      (ii) Second Priority Lien Debt have tenors that expire on or prior to the
      Stated Maturity of the Second Priority Notes, or (iii) Third Priority Lien
      Debt have tenors that expire on or prior to the Stated Maturity of the
      Third Priority Notes;

            (7)   the incurrence by the Company or any of its Subsidiaries of
      Indebtedness in respect of workers' compensation claims, self-insurance
      obligations, bankers' acceptances, and performance and surety bonds in the
      ordinary course of business;

            (8)   the incurrence by the Company or any of its Subsidiaries of
      Indebtedness arising from the honoring by a bank or other financial
      institution of a check, draft or similar instrument inadvertently drawn
      against insufficient funds, so long as such Indebtedness is covered within
      five Business Days;

            (9)   the incurrence by the Company of (a) Affiliate Subordinated
      Indebtedness in an aggregate principal amount not to exceed $250.0 million
      at any one time outstanding and (b) Working Capital Facility Indebtedness
      in an aggregate principal amount not to exceed $750.0 million at any one
      time outstanding;

            (10)  the incurrence by the Company of Third Parry Subordinated
      Indebtedness; provided, that:

                                       71

<PAGE>

                  (a)   the net proceeds of the Third Party Subordinated
            Indebtedness are applied:

                              (i)   to acquire all or substantially all of the
                  assets of, or any Equity Interests in, a business that
                  constitutes a Permitted Business; provided, that in the case
                  of an acquisition of Equity Interests, the business is or
                  becomes a Subsidiary of the Company and a Guarantor
                  concurrently with such acquisition;

                              (ii)  to make a capital expenditure;

                              (iii) to acquire other assets that are not
                  classified as current assets under GAAP and that are used or
                  useful in a Permitted Business; or

                              (iv)  any combination of the foregoing; and

                        (b)   the Fixed Charge Coverage Ratio for the Company's
            most recently ended four full fiscal quarters for which internal
            financial statements are available immediately preceding the date on
            which the Third Party Subordinated Indebtedness is incurred would
            have been at least 2.0 to 1.0, determined on a Pro Forma basis as if
            the Third Party Subordinated Indebtedness had been incurred at the
            beginning of such period and the proceeds therefrom had been applied
            as intended to be applied (but without giving effect to the
            completion of any construction projects unless actual completion has
            been achieved).

      The Company will not incur, and will not permit any Subsidiary to incur,
any Indebtedness (including Permitted Debt) that is contractually subordinated
in right of payment to any other Indebtedness of the Company or such Subsidiary
unless such Indebtedness is also contractually subordinated in right of payment
to the Secured Obligations on substantially identical terms or on terms that are
more favorable to the holders of the Secured Obligations; provided, however,
that no Indebtedness will be deemed to be contractually subordinated in right of
payment to any other Indebtedness of the Company or any of its Subsidiaries
solely by virtue of being unsecured or by virtue of being secured on a junior
basis.

      For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (10) above,
the Company will be permitted to classify such item of Indebtedness on the date
of its incurrence, or later reclassify all or a portion of such item of
Indebtedness, in any manner that complies with this Section 4.09. The accrual
of interest, the accretion or amortization of original issue discount, the
payment of interest on any Indebtedness in the form of additional Indebtedness
with the same terms, and the payment of dividends on Disqualified Stock in the
form of additional shares of the same class of Disqualified Stock will not be
deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock
for purposes of this covenant. Notwithstanding any other provision of this
covenant, the maximum amount of Indebtedness that the Company or any Subsidiary
may incur pursuant to this covenant shall not be deemed to be exceeded solely as
a result of fluctuations in exchange rates or currency values.

Section 4.10 Asset Sales.

      The Company will not, and will not permit any of its Subsidiaries to,
consummate any Asset Sale unless:

                                       72

<PAGE>

            (1)   except with respect to an Asset Sale made pursuant to an
      Existing Purchase Option, the Company (or any of its Subsidiaries, as the
      case may be) receives consideration at the time of the Asset Sale at least
      equal to the Fair Market Value of the assets or Equity Interests issued or
      sold or otherwise disposed of;

            (2)   at least 90% of the consideration received in the Asset Sale
      by the Company or such Subsidiary is in the form of cash. For purposes of
      this provision, each of the following will be deemed to be cash;

                  (a)   any liabilities, as shown on the Company's most recent
            consolidated balance sheet, of the Company or any of its
            Subsidiaries (other than contingent liabilities and liabilities that
            are by their terms subordinated to the Notes or any Subsidiary
            Guarantee) that are assumed by the transferee of any such assets
            pursuant to a customary novation or similar agreement that releases
            the Company or such Subsidiary from further liability;

                  (b)   any securities, notes or other obligations received by
            the Company or any such Subsidiary from such transferee that are
            promptly, subject to ordinary settlement periods, converted by the
            Company or such Subsidiary into cash, to the extent of the cash
            received in that conversion; and

                  (c)   in connection with the exercise by a purchaser of an
            Existing Purchase Option, any amount owed by the Company or the
            applicable Subsidiary to the purchaser under the agreement
            containing such Existing Purchase Option that is set off by the
            purchaser against the purchase price;

            (3)   if the assets disposed of in such Asset Sale include any
      component of a Facility that is necessary for the operation of such
      Facility, the Asset Sale involves the disposition of such Facility as a
      whole; and

            (4)   if the Asset Sale involves the sale of a Facility or all or
      substantially all the assets of a Facility, (a) such Asset Sale is to a
      Person other than an Affiliate of the Company, and (b) all necessary
      amendments are made to those Major Project Documents applicable to such
      Facility to remove such Facility from the scope of such Major Project
      Documents.

      The Company and its Subsidiaries will be required to use the Net Proceeds
from any Asset Sale, Casualty Event or Condemnation Event to make an offer (an
"Asset Sale Offer"):

                  (1)   first, to all holders of Notes and all holders of other
            First Priority Lien Obligations (to the extent required under the
            applicable First Priority Lien Documents) to purchase, prepay or
            redeem the maximum principal amount of Notes and such other First
            Priority Lien Obligations that may be purchased, prepaid or redeemed
            out of such Net Proceeds (taking into account any mandatory
            purchase, prepayment or redemption of First Priority Lien
            Obligations required under any First Priority Lien Document);

                  (2)   second, if any such Net Proceeds remain after the offer
            to holders of First Priority Lien Obligations (and any mandatory
            purchase, prepayment or redemption of First Priority Lien
            Obligations) in accordance with clause (1) above, to all holders of
            Second Priority Notes and all holders of other Second Priority Lien
            Obligations (to the extent required under the applicable Second
            Priority Lien Documents) to purchase, prepay or redeem the maximum
            principal amount of Second Priority Notes and such other Second

                                       73

<PAGE>

            Priority Lien Obligations that may be purchased, prepaid or redeemed
            out of such remaining Net Proceeds (taking into account any
            mandatory purchase, prepayment or redemption of Second Priority Lien
            Obligations required under any Second Priority Lien Document); and

                  (3)   third, if any such Net Proceeds remain after the offer
            to holders of First Priority Lien Obligations and Second Priority
            Lien Obligations (and any mandatory purchase, prepayment or
            redemption of First Priority Lien Obligations and Second Priority
            Lien Obligations) in accordance with clauses (1) and (2) above, to
            all holders of Third Priority Notes and all holders of other Third
            Priority Lien Obligations (to the extent required under the
            applicable Third Priority Lien Documents) to purchase, prepay or
            redeem the maximum principal amount of Third Priority Notes and such
            other Third Priority Lien Obligations that may be purchased, prepaid
            or redeemed out of such remaining Net Proceeds (taking into account
            any mandatory purchase, prepayment or redemption of Third Priority
            Lien Obligations required under any Third Priority Lien Document).

      The Issuers may, at their sole option, make an Asset Sale Offer in
accordance with the priorities described above with the net proceeds from any
sale, lease, conveyance or other disposition of any assets or rights not
constituting an Asset Sale. The offer price in any Asset Sale Offer will be
equal to 100% of the principal amount plus accrued and unpaid interest and
Special Interest, if any, to the date of purchase, and will be payable in cash.
If any of such Net Proceeds remain after consummation of the Asset Sale Offer,
the Company and its Subsidiaries may use those excess Net Proceeds for any
purpose not otherwise prohibited by this Indenture, including the making of
Restricted Payments in accordance with Section 4.07. If the aggregate principal
amount of Notes and other First Priority Lien Obligations tendered into such
Asset Sale Offer or required to be purchased, prepaid or redeemed exceeds the
amount of Net Proceeds available therefor, the Issuers will purchase, prepay or
redeem Notes and such other First Priority Lien Obligations on a pro rata basis
based on the principal amount of Notes and such other First Priority Lien
Obligations tendered (or required to be purchased, prepaid or redeemed), with
such adjustments as may be deemed appropriate by the Company so that only Notes
in denominations of $1,000, or integral multiples thereof, will be purchased,
prepaid or redeemed. The Issuers will comply with the procedures set forth in
Section 3.09 with respect to any Asset Sale Offer.

Section 4.11 Transactions with Affiliates.

      The Company will not, and will not permit any of its Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate of the Company
(each, an "Affiliate Transaction"), unless:

            (1)   the Affiliate Transaction, taken as a whole with all other
      related Affiliate Transactions, is on terms that are no less favorable to
      the Company and its Subsidiaries, taken as a whole, than those that would
      have been obtained in a comparable transaction by the Company or such
      Subsidiary with an unrelated Person; and

            (2)   the Company delivers to the Trustee (other than with respect
      to a Shared Facilities Arrangement between or among the Company and/or any
      of its Subsidiaries):

                  (a)   with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $10.0 million but less than or

                                       74

<PAGE>

            equal to $25.0 million, a resolution of the Board of Directors set
            forth in an Officer's Certificate certifying that such Affiliate
            Transaction complies with this covenant and that such Affiliate
            Transaction has been approved by a majority 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 $25.0 million, a positive opinion as to the Fair Market
            Value of such Affiliate Transaction issued by an accounting,
            appraisal or investment banking firm of national standing.

      The following items will not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

            (1)   any employment agreement, employee benefit plan, officer and
      director indemnification agreement or any similar arrangement entered into
      by the Company or any of its Subsidiaries in the ordinary course of
      business;

            (2)   transactions between or among the Company and/or any of the
      Guarantors (other than Shared Facility Arrangements);

            (3)   transactions with a Person that is an Affiliate of the Company
      (but not a Subsidiary of the Company) solely because the Company owns,
      directly or through a Subsidiary, an Equity Interest in, or controls, such
      Person;

            (4)   payment of reasonable directors' fees to Persons who are not
      otherwise Affiliates of the Company;

            (5)   any issuance of Equity Interests (other than Disqualified
      Stock) of the Company to Affiliates of the Company; provided, that such
      Equity Interests are included in the Collateral;

            (6)   Restricted Payments that do not violate Section 4.07;

            (7)   loans or advances to employees in the ordinary course of
      business not to exceed $ 1.0 million in the aggregate at any one time
      outstanding;

            (8)   Permitted Tax Payments;

            (9)   transactions under or pursuant to written agreements with
      Affiliates of the Company in place as of the Closing Date or any amendment
      or modification thereto, so long as any such amendment or modification
      meets the requirements of clause (10) or (11) of this paragraph;

            (10)  any amendments or modifications of, or waivers under, any
      written agreement described under clause (9) of this paragraph that is not
      a Major Project Document; provided, that no such amendment, modification
      or waiver alters any such agreement in a manner that is materially adverse
      to the Holders;

            (11)  any amendments or modifications of, or waivers under, any
      Major Project Document, which are permitted by Section 4.13 and are on
      terms that are no less favorable to the Company or its relevant Subsidiary
      (as certified to the Trustee in an Officer's Certificate) than those that
      would have been obtained in a comparable transaction by the Company or
      such Subsidiary with an unrelated Person; and

                                       75

<PAGE>

            (12)  any agreement to do any of the foregoing.

Section 4.12 Liens.

      The Company will not, and will not permit any of its Subsidiaries to,
directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind on any asset now owned or hereafter acquired, except Permitted Liens.

Section 4.13 Business Activities.

      The Company will not, and will not permit any of its Subsidiaries to,
engage in any business other than Permitted Businesses, except to such extent as
would not be material to the Company and its Subsidiaries taken as a whole.

      The Company will, and will cause its Subsidiaries to, perform all their
obligations under the Major Project Documents, and the Company will not, and
will not permit any of its Subsidiaries to, terminate, amend or otherwise
modify, or consent to any termination, amendment or modification of, or grant
any waiver under, any Major Project Document, unless any failure to so perform
or any such termination, amendment, modification or waiver would not, when taken
together with all other such failures to perform, terminations, amendments,
modifications and waivers since the Closing Date, be Materially Adverse, as
evidenced by a certificate of the chief financial officer of the Company;
provided, however, that the provisions of this paragraph will not apply to any
amendment, modification or termination of any Major Project Document required
under this Indenture in connection with an Asset Sale.

      The Company will, and will cause its Subsidiaries to, obtain and maintain
all permits and approvals necessary for the construction and operation of the
Facilities, including applicable exemptions from PUHCA, unless the failure to do
so would not reasonably be expected to have a Material Adverse Effect.

      The Company will not, and will not permit any of its Subsidiaries to, use
or dispose of any hazardous materials or allow any hazardous materials to be
brought onto or stored or used on or transported to or released from the
Facilities, other than in accordance with prudent industry practices and in
compliance with all applicable environmental laws, except to the extent such
non-compliance, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect.

Section 4.14 Corporate Existence.

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

            (1)   its corporate existence, and the corporate, partnership or
      other existence of each of its Subsidiaries, in accordance with the
      respective organizational documents (as the same may be amended from time
      to time) of the Company or any such Subsidiary; and

            (2)   the rights (charter and statutory), licenses and franchises of
      the Company and its Subsidiaries; provided, however, that the Company will
      not be required to preserve any such right, license or franchise, or the
      corporate, partnership or other existence of any of its 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
      Subsidiaries, taken as a whole, and that the loss thereof is not adverse
      in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

      (a)   Upon the occurrence of a Change of Control, the Issuers will make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple of $1,000) of such Holder's Notes at a
purchase price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest and Special Interest, if any, on the Notes
repurchased, to, but excluding, the date of purchase (the "Change of Control
Payment"), subject to the rights of Holders on the relevant record date to
receive interest due on the relevant interest payment date. Within 30 days
following any Change of Control, the Issuers will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and stating:

            (1)   that the Change of Control Offer is being made pursuant to
      this Section 4.15 and that all Notes tendered will be accepted for
      payment;

            (2)   the purchase price and the purchase date, which shall be no
      earlier than 30 days and no later than 60 days from the date such notice
      is mailed (the "Change of Control Payment Date");

            (3)   that any Note not tendered will continue to accrue interest;

            (4)   that, unless the Issuers default in the payment of the Change
      of Control Payment, all Notes accepted for payment pursuant to the Change
      of Control Offer will cease to accrue interest after the Change of Control
      Payment Date;

            (5)   that Holders electing to have any Notes purchased pursuant to
      a Change of Control Offer will be required to surrender the Notes, with
      the form entitled "Option of Holder to Elect Purchase" on the reverse of
      the 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 Notes delivered for purchase, and a
      statement that such Holder is withdrawing his election to have the Notes
      purchased; and

            (7)   that Holders whose Notes are being purchased only in part will
      be issued new Notes equal in principal amount to the unpurchased portion
      of the Notes surrendered, which unpurchased portion must be equal to
      $1,000 in principal amount or an integral multiple thereof.

      The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change in Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Sections 4.15, the Issuers will comply with the applicable
securities laws and regulations and will not be deemed to have breached their
obligations under this Section 4.15 by virtue of such compliance.

      (b)   On the Change of Control Payment Date, the Issuers will, to the
extent lawful:

            (1)   accept for payment all Notes or portions thereof properly
      tendered pursuant to the Change of Control Offer;

                                       77

<PAGE>

            (2)   deposit with the Paying Agent an amount equal to the Change of
      Control Payment in respect of all Notes or portions of Notes properly
      tendered; and

            (3)   deliver or cause to be delivered to the Trustee the Notes so
      properly accepted together with an Officer's Certificate stating the
      aggregate principal amount of Notes or portions of Notes being purchased
      by the issuers.

      The Paying Agent will promptly mail to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee, at the
written request of the Company, will promptly authenticate and mail (or cause to
be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided,
that each new Note will be in a principal amount of $1,000 or an integral
multiple thereof.

      The Issuers will publicly announce the results of the Change of Control
Offer on or as soon as practicable after the Change of Control Payment Date.

      The provisions described above that require the Issuers to make a Change
of Control Offer following a Change in Control will be applicable whether or not
any other provisions of this Indenture are applicable. Except as described above
with respect to a Change in Control, this Indenture does not contain provisions
that permit the Holders to require that the Issuers repurchase or redeem the
Notes in event of a takeover, recapitalization or similar transaction.

      (c)   Notwithstanding anything to the contrary in this Section 4.15, the
Issuers will not be required to make a Change of Control Offer upon a Change of
Control if (1) 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 this
Section 4.15 and purchases all Notes properly tendered and not withdrawn under
the Change of Control Offer, or (2) notice of redemption has been given pursuant
to Section 3.07, unless and until there is a default in payment of the
applicable redemption price.

Section 4.16 Limitation on Issuances and Sales of Equity Interests in
Subsidiaries.

      The Company will not, and will not permit any of its Subsidiaries to,

Guarantor), unless:

            (1)   such transfer, conveyance, sale, lease or other disposition is
      of all the Equity Interests in such Subsidiary; and

            (2)   the Net Proceeds from such transfer, conveyance, sale, lease
      or other disposition are applied in accordance with Section 4,10.

      In addition, the Company will not permit any Subsidiary of the Company to
issue any of its Equity Interests (other than, if necessary, shares of its
Capital Stock constituting directors' qualifying shares) to any Person other
than to the Company or a Guarantor.

Section 4.17 Payments for Consent.

      The Company will not, and will not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of any Note Document unless such

                                       78

<PAGE>

consideration is offered to be paid and is paid to all Holders that Consent,

Section 4.18 Restrictions on Activities of CalGen Finance.

      CalGen Finance will not hold any material assets, become liable for any
material obligations or engage in any significant business activities; provided,
that CalGen Finance may be a co-obligor or guarantor with respect to

proceeds of such Indebtedness are received by the Company, CalGen Finance or one
or more of the Company's other Subsidiaries.

Section 4.19 Deposit of Revenues.

      The Company will, and will cause its Subsidiaries to, deposit all revenues

thereof, in the "Revenue Account" established under the Control Agreement.
Notwithstanding the foregoing, Excess Cash Flow may be distributed in accordance
with Section 4.07.

Section 4.20 Additional Subsidiaries.

      If the Company or any of its Subsidiaries acquires or creates another
Subsidiary after the Closing Date, then (1) that newly acquired or created
Subsidiary will become a Guarantor and execute a supplemental indenture in the
form of Exhibit G and deliver an Opinion of Counsel reasonably satisfactory to
the Trustee within 30 days of the date on which it was acquired or created, and
(2) all real and personal property of that Subsidiary will become part of the
Collateral within 30 days of the date on which that Subsidiary was acquired or

and the Collateral Agent.

Section 4.21 Maintenance of Insurance.

      The Company will, and will cause its Subsidiaries to, maintain with
financially sound and reputable insurance companies, insurance on their property
and assets (including the Collateral), in at least such amounts, with such
deductibles and against at least such risks as is customary for companies of the
same or similar size engaged in the same or similar businesses as those of the
Company and its Subsidiaries and furnish to the Collateral Agent, upon written
request, full information as to such Persons' property and liability insurance
carriers. The Company will, and will cause the Guarantors to, cause all their
insurance policies to name the Secured Parties, as a class, as additional
insureds, with a waiver of subrogation, and shall cause all their property and
casualty policies to name the Collateral Agent as loss payee (together with

Capacity of all of the Facilities (including all Facilities in operation and

                                       79

<PAGE>

under construction) owned by the Company and its Subsidiaries (expressed in
kilowatts), as of the end of each fiscal quarter of the Company, to be equal to
or less than $235 per kilowatt.

Section 4.23 Changes in Covenants when Third Priority Notes Rated Investment
Grade.

      If on any date following the Closing Date:

            (1)   after giving effect to the suspension of covenants (and the
      Event of Default) described below in the Third Priority Indenture, the
      Third Priority Notes are rated Baa3 or better by Moody's and BBB- or
      better by S&P; and

            (2)   no Default or Event of Default shall have occurred and then be
      continuing,

then, beginning on that day and subject to the provisions of the following
paragraph, the covenants (and the Event of Default) of this Indenture
specifically listed below will be suspended:

            (a)   Section 4.07 (Restricted Payments);

            (b)   Section 4.08 (Dividend and Other Payment Restrictions
      Affecting Subsidiaries);

            (c)   Section 4.09 (Incurrence of Indebtedness and Issuance of
      Preferred Equity);

            (e)   Section 4.10 (Deposit of Revenues);

            (d)   Section 4.13 (Business Activities); and

            (f)   clause (9) under Section 6.01 (Events of Default).

      Notwithstanding the foregoing, if the rating assigned to the Third
Priority Notes by either Moody's or S&P should subsequently decline to below
Baa3 or BBB-, respectively, the foregoing covenants (and the Event of Default)
will be reinstituted with respect to the Notes as of and from the date of such
rating decline. Calculations under reinstated Section 4.07 will be made as if
such covenant had been in effect since the Closing Date except that no Default
will be deemed to have occurred solely by reason of a Restricted Payment made
while such covenant was suspended.

            (2)   sell, assign, transfer, convey or otherwise dispose of all or
      substantially all of the properties or assets of the Company and its
      Subsidiaries taken as a whole, in one or more related transactions, to

Affiliate solely for the purpose of reconstituting the Company in another
jurisdiction or (B) any sale, assignment, transfer, conveyance, lease or other
disposition of assets between or among the Company and the Guarantors.

     Notwithstanding the foregoing, the Company is permitted to reorganize as a
corporation in accordance with the procedures established herein, provided, that
the Company shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that such
reorganization is not adverse to Holders (it being recognized that such
reorganization shall not be deemed adverse to the Holders solely because (i) of
the accrual of deferred tax liabilities resulting from such reorganization or
(ii) the successor or surviving corporation (a) is subject to income tax as a
corporate entity or (b) is considered to be an "includable corporation" of an
affiliated group of corporations within the meaning of the Internal Revenue Code
of 1986, as amended or any similar state or local law), and the Company delivers
to the Trustee such other certificates and other documents reasonably requested
by the Trustee in connection therewith.

     Upon any consolidation or merger, or any sale, assignment, transfer, lease,
conveyance or other disposition of all or substantially all of the assets of the
Company and its Subsidiaries taken as a whole in a transaction that is subject
to, and that complies with the provisions of, Section 5.01, the successor
corporation formed by such consolidation 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, merger, sale, lease, conveyance or other
disposition, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation and not to the Company), 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 interest on the Notes except in the case
of a sale of all of the Company's assets in a transaction that is subject to,
and that complies with the provisions of, Section 5.01.

     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Subsidiaries
     (or the payment of which is guaranteed by the Company or any of its
     Subsidiaries), whether such Indebtedness or guarantee existed on the
     Closing Date or is created after the Closing Date, if that default:

     repudiation or unenforceability relates to Collateral with a Fair Market
     Value of $25.0 million or more;

          (8)  except as permitted by this Indenture, any Subsidiary Guarantee
     shall be held in any judicial proceeding to be unenforceable or invalid or

     including by entering into a replacement agreement), be Materially Adverse,
     as evidenced by an Officer's Certificate of the chief financial officer of
     the Company), unless with respect to any Major Project Document such breach
     is cured, or such Major Project Document is replaced with a substantially
     similar agreement (it being understood that (a) an agreement will be
     considered substantially similar if it would not be Materially Adverse and
     (b) the use of an Affiliate of the Company as the counterparty under an
     agreement replacing the Index Hedge will not by itself be considered
     Materially Adverse), within 60 days (or 120 days with respect to the Index
     Hedge) thereafter; and

               (b)  appoints a custodian of the Company, any of its Subsidiaries
          that is a Significant Subsidiary or any group of its Subsidiaries that

Section 6.02 Acceleration.

     In the case of an Event of Default specified in clause (10) or (11) of
Section 6.01, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. Upon any such declaration, the Notes shall become due and
payable immediately.

     The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, 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 or Special Interest, if
any, that has become due solely because of the acceleration) have been cured or
waived.

Section 6.03 Other Remedies.

                                       83

<PAGE>

available remedy to collect the payment of principal, premium, if any, and
interest and Special Interest, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a 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 a majority in aggregate principal amount of the then outstanding
Notes by written notice to the Trustee may, on behalf of the Holders of all of
the 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 the
principal of, premium and Special Interest, if any, or interest on, the Notes
(including in connection with an offer to purchase). 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.

     Subject to the provisions of the Collateral Trust Agreement, Holders of a
majority in aggregate principal amount of the then outstanding Notes 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
the rights of other Holders of Notes or that may involve the Trustee in personal
liability.

Section 6.06 Limitation on Suits.

     Except to enforce the right to receive payment of principal, premium, if
any, or interest or Special Interest, if any, when due, no Holder may pursue any
remedy with respect to this Indenture or the Notes unless:

     of Default is continuing;

          (2)  Holders of at least 25% in aggregate principal amount of the then
     outstanding Notes have requested that the Trustee pursue the remedy;

          (3)  such Holders have offered the Trustee reasonable security or
     indemnity against any loss, liability or expense;

          (4)  the Trustee has not complied with such request within 60 days
     after the receipt thereof and the offer of security or indemnity; and

          (5)  Holders of a majority in aggregate principal amount of the Notes
     then outstanding have not given the Trustee a direction inconsistent with
     such request within such 60-day period.

                                       84

<PAGE>

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Special Interest,
if any, and interest on the Note, on or after the respective due dates expressed
in the 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; provided,
that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution
thereof or the entry of judgment therein would, under applicable law, result in
the surrender, impairment, waiver or loss of the Lien of this Indenture upon any
property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(1) or (2) occurs and is

expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the 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

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

disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 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 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 6.11 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 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 6.11
does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant
to Section 6.07, or a suit by Holders of more than 10% in aggregate principal
amount of the then outstanding Notes.

                                   ARTICLE 7.
                                     TRUSTEE

Section 7.01 Duties of Trustee.

     (a)  If an Event of Default has occurred and is continuing, the Trustee
will 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 person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

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

          (1)  the duties of the Trustee will be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

          (2)  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 will examine the certificates and opinions to determine whether
     or not they conform to the requirements of this Indenture (but need not
     confirm or investigate the accuracy of any calculations or other facts
     stated therein).

     (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:

                                       86

<PAGE>

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

          (2)  the Trustee will not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it is conclusively determined
     by a court of competent jurisdiction that the Trustee was negligent in
     ascertaining the pertinent facts; and

          (3)  the Trustee will 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.

     (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.

     (e)  No provision of this Indenture will require the Trustee to expend or
risk its own funds or incur any liability. The Trustee will be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holder, unless such Holder has offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense.

     (f)  The Trustee will 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 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
Officer's Certificate or an Opinion of Counsel or both. The Trustee will not be
liable for any action it takes or omits to take in good faith in reliance on
such Officer's Certificate or Opinion of Counsel. The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel will 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 attorneys and agents and will not be
responsible for the misconduct or negligence of any agent appointed with due
care.

     (d)  The Trustee will 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 will be sufficient if signed by an
Officer of the Company.

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

     (g)  In no event shall the Trustee be required to take notice of any
default or breach hereof or any Event of Default hereunder unless and until the
Trustee shall have received from a Holder of a Note

                                       87

<PAGE>

or from the Company written notice of the circumstances constituting the breach,
default or Event of Default and stating that said circumstances constitute an
Even of Default hereunder.

     (h)  If the Trustee is acting as Paying Agent and/or Registrar hereunder,
the rights and protections afforded to the Trustee pursuant to this Article 7
will also be afforded to such Paying Agent and Registrar.

Section 7.03 Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of 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 after determining such conflicting interest, apply
to the SEC for permission to continue as trustee or resign to the extent and in
the manner provided by, and subject to the provisions of, the TIA and this
Indenture. Any Agent may do the same with like rights and duties. The Trustee is
also subject to Sections 7.10 and 7.11.

Section 7.04 Trustee's Disclaimer.

     The Trustee will not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the 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 will mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium or Special
Interest, if any, or interest on any 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
Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

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

     (b)  A copy of each report at the time of its mailing to the Holders of
Notes will be mailed by the Trustee to the Company and filed by the Trustee with
the SEC and each stock exchange on which the Notes are listed in accordance with
TIA Section 313(d). The Company will promptly notify the Trustee when the Notes
are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

                                       88

<PAGE>

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

     (b)  The Company and the Guarantors will indemnify the Trustee against any
and all losses, liabilities or expenses incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture and any other Note Documents to which it is a party, including the
costs and expenses of enforcing this Indenture and any other Note Documents to
which it is a party against the Company and the Guarantors (including this
Section 7.07) and defending itself against any claim (whether asserted by the
Company, the Guarantors, any Holder or any other Person) or liability, loss or
expense incurred by it in connection with the exercise or performance of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith as finally determined
by a court of competent jurisdiction. The Trustee will notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company will not relieve the Company or any of the Guarantors of
their obligations hereunder. The Company or such Guarantor will defend the claim
and the Trustee will cooperate in the defense. The Trustee may have separate
counsel and the Company will pay the reasonable fees and expenses of such
counsel. Neither the Company nor any Guarantor need pay for any settlement made
without its consent, which consent will not be unreasonably withheld.

     (c)  The obligations of the Company and the Guarantors under this Section
7.07 will survive the satisfaction and discharge of this Indenture.

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

     (e)  When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(10) or (11) 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.

     (f)  The Trustee will comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

Section 7.08 Replacement of Trustee.

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

     (b)  The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

          (1)  the Trustee fails to comply with Section 7.10;

                                       89

<PAGE>

          (2)  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;

          (3)  a custodian or public officer takes charge of the Trustee or its
     property; or

          (4)  the Trustee becomes incapable of acting.

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

     (d)  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 aggregate principal amount of the then
outstanding Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

     (e)  If the Trustee, after written request by any Holder who has been a
Holder for at least six months, fails to comply with Section 7.10, such Holder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

     (f)  A successor Trustee will deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the
successor Trustee will have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee will mail a notice of its succession
to Holders. The retiring Trustee will promptly transfer all property held by it
as Trustee to the successor Trustee, provided, that all sums owing to the
Trustee hereunder have been paid and subject to the Lien provided for in Section
7.07. Notwithstanding replacement of the Trustee pursuant to this Section 7.08,
the Company's obligations under Section 7.07 will 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 will be the successor
Trustee.

Section 7.10 Eligibility; Disqualification.

     There will 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 (i) in the case of the initial Trustee, that also satisfies the
eligibility requirements for a trustee under the TIA and (ii) in the case of any
successor Trustee, that has a combined capital and surplus of at least $100
million as set forth in its most recent published annual report of condition.

     This Indenture will always have a Trustee who satisfies the requirements of

310(b).

                                       90

<PAGE>

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

                                  ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

     The Issuers may, at their option at any time, elect to have either Section
8.02 or 8.03 be applied to all outstanding Notes upon compliance with the
conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

     Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.02, the Issuers and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be deemed to have been
discharged from their obligations with respect to all outstanding Notes
(including the Subsidiary Guarantees) on the date the conditions set forth below
are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal
Defeasance means that the Issuers and the Guarantors will be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Notes
(including the Subsidiary Guarantees), which will thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 and the other Sections of
this Indenture referred to in clauses (1) and (2) below, and to have satisfied
all their other obligations under such Notes, the Subsidiary Guarantees 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 will survive until otherwise terminated or discharged
hereunder:

          (1)  the rights of Holders of outstanding Notes to receive payments in
     respect of the principal of, or interest or premium or Special Interest, if
     any, on such Notes when such payments are due from the trust referred to in
     Section 8.04;

          (2)  the Issuers' obligations with respect to such Notes under Article
     2 and Section 4.02;

          (3)  the rights, powers, trusts, duties and immunities of the Trustee
     hereunder and the Issuers' and the Guarantors' obligations in connection
     therewith; and

          (4)  this Article 8.

     Subject to compliance with this Article 8, the Issuers may exercise their
option under this Section 8.02 notwithstanding the prior exercise of their
option under Section 8.03.

Section 8.03 Covenant Defeasance.

     Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.03, the Issuers and the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be released from each
of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 4.21 and 4.22 with
respect to the outstanding Notes on and after the date the conditions set forth
in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the
Notes will thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in

                                       91

<PAGE>

connection with such covenants, but will continue to be deemed "outstanding" for
all other purposes hereunder (it being understood that such Notes may not be
deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Subsidiary
Guarantees, the Issuers and the Guarantors may omit to comply with and will 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 will not constitute a Default or an Event of Default under
Section 6.01, but, except as specified above, the remainder of this Indenture
and such Notes and Subsidiary Guarantees will be unaffected thereby. In
addition, upon the Issuers' exercise under Section 8.01 of the option applicable
to this Section 8,03, subject to the satisfaction of the conditions set forth in
Section 8.04, Sections 6.01(3) through 6.01(5) will not constitute Events of
Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

     In order to exercise either Legal Defeasance or Covenant Defeasance under
either Section 8.02 or 8.03:

          (1)  the Issuers must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders, cash in United States dollars, non-callable
     Government Securities, or a combination thereof, in such amounts as will be
     sufficient, in the opinion of a nationally recognized investment bank,
     appraisal firm or firm of independent public accountants, to pay the
     principal of, or interest and premium and Special Interest, if any, on the
     outstanding Notes on the Stated Maturity or on the applicable redemption
     date, as the case may be, and the Issuers must specify whether the Notes
     are being defeased to maturity or to a particular redemption date;

          (2)  in the case of an election under Section 8.02, the Issuers must

     reasonably acceptable to the Trustee confirming that:

               (A)  the Issuers have received from, or there has been published
          by, the Internal Revenue Service a ruling; or

               (B)  since the Closing Date, 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 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;

          (3)  in the case of an election under Section 8.03, the Issuers have
     delivered to the Trustee an Opinion of Counsel in the United States
     reasonably acceptable to the Trustee confirming that the Holders of the
     outstanding Notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such Covenant 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 Covenant Defeasance
     had not occurred;

                                       92

<PAGE>

          (4)  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 borrowing of funds to be applied to such
     deposit);

          (5)  such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute a default under, any material
     agreement or instrument to which the Company or any of its Subsidiaries is
     a party or by which the Company or any of its Subsidiaries is bound;

          (6)  the Issuers must deliver to the Trustee an Officer's Certificate
     stating that the deposit was not made by the Issuers with the intent of
     preferring the Holders of Notes over the other creditors of the Issuers
     with the intent of defeating, hindering, delaying or defrauding creditors
     of the Issuers or others; and

          (7)  the Issuers must deliver to the Trustee an Officer's Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     provided for or relating to the Legal Defeasance or the Covenant Defeasance
     have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions.

     Subject to Section 8.06, all money and non-callable Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant
to Section 8.04 in respect of the outstanding Notes will be held in trust and
applied by the Trustee, in accordance with the provisions of such Notes and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Notes of all sums due and to become due thereon in respect
of principal, premium and Special Interest, if any, and interest, but such money
need not be segregated from other funds except to the extent required by law.

     The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 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 Notes.

     Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Issuers from time to time upon the request of the
Issuers any money or non-callable Government Securities held by them as provided
in Section 8.04 which, in the opinion of a nationally recognized investment
bank, appraisal firm or 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(1)), 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 to Company.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Issuers, in trust for the payment of the principal of, premium and Special
Interest, if any, or interest on any Note and remaining unclaimed for two years
after such principal, premium and Special Interest, if any, or interest has
become due and payable shall be paid to the Issuers on their request or (if then
held by the Issuers) will be discharged from such trust; and the Holder of such
Note will thereafter be permitted to look only to the Issuers for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to

                                       93

<PAGE>

such trust money, and all liability of the issuers as trustee thereof, will
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 will 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 Issuers.

Section 8.07 Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States dollars
or non-callable Government Securities in accordance with Section 8.02 or 8.03,
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 Issuers' and the Guarantors' obligations under this
Indenture, the Notes and the Subsidiary Guarantees will be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
until such time as the Trustee or Paying Agent is permitted to apply all such
money in accordance with Section 8.02 or 8.03, as the case may be; provided,
however, that, if the Issuers make any payment of principal of, premium or
Special Interest, if any, or interest on any Note following the reinstatement of
their obligations, the Issuers will be subrogated to the rights of the Holder of
such Note to receive such payment from the money held by the Trustee or Paying
Agent.

                                   ARTICLE 9.

Subsidiary Guarantees or the Notes:

          (1)  to cure any ambiguity, defect or inconsistency;

          (2)  to provide for uncertificated Notes in addition to or in place of

     Holders of the Notes by a successor to the Issuers pursuant to Article 5;

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

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

          (6)  to make, complete or confirm any grant of Collateral permitted or
     required by this Indenture or any of the Security Documents or any release
     of Collateral that becomes effective as set forth in this Indenture or any
     of the Security Documents;

          (7)  to conform the text of this Indenture, the Subsidiary Guarantees,
     the Security Documents or the Notes to any provision of the "Description of
     Notes" section contained in the Offering Memorandum to the extent that such
     provision in such "Description of Notes" section was intended to be a
     verbatim recitation of a provision of this Indenture, the Subsidiary
     Guarantees, the Security Documents or the Notes; or

                                       94

<PAGE>

          (8)  to allow any Guarantor to execute a supplemental indenture in the
     form of Exhibit G and/or a Subsidiary Guarantee with respect to the Notes.

     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, the Trustee will join with the Company and the Guarantors 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 will not be obligated to enter
into such amended or supplemental indenture mat affects its own rights, duties
or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

     Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.15), the Subsidiary Guarantees and the Notes with the consent
of the Holders of at least a majority in aggregate principal amount of the Notes
then outstanding voting as a single class (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for, or
purchase of, the Notes), and, subject to Sections 6.04 and 6.07, any existing
Default or Event of Default (other than a Default or Event of Default in the
payment of the principal of, premium or Special Interest, if any, or interest on
the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture, the Subsidiary
Guarantees or the Notes may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Notes voting as a
single class (including consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). Section 2.08 shall determine
which Notes are considered to be "outstanding" for purposes of this Section
9.02.

     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 Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02, the Trustee will join
with the Company in the execution of such amended or supplemental indenture
unless such amended or supplemental indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but will not be obligated to, enter into such
amended or supplemental indenture.

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

     After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company will mail to the Holders of 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, will 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, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder):

                                       95

<PAGE>

          (1)  reduce the principal amount of Notes whose Holders must consent
     to an amendment, supplement or waiver;

          (2)  reduce the principal of or change the fixed maturity of any Note
     or alter the provisions with respect to the redemption of the Notes (other
     than the provisions of Sections 3.09, 4.10 and 4.15);

          (3)  reduce the rate of or change the time for payment of interest,
     including default interest, on any Note;

          (4)  waive a Default or Event of Default in the payment of principal
     of, or premium, interest or Special Interest, if any, on, the Notes (except
     a rescission of acceleration of the Notes by the Holders of at least a
     majority in aggregate principal amount of the then outstanding Notes and a
     waiver of the payment default that resulted from such acceleration);

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

          (6)  make any change in the provisions of this Indenture relating to
     waivers of Defaults or Events of Default or the rights of Holders of Notes
     to receive payments of principal of, or interest, premium or Special
     Interest, if any, on the Notes;

          (7)  waive a redemption payment with respect to any Note (other than a
     payment required under Section 4.10 or Section 4.15);

          (8)  release any Guarantor from any of its payment obligations under
     its Subsidiary Guarantee or this Indenture, except in accordance with the
     terms of this Indenture;

          (9)  release any portion of the Collateral from the Liens created by
     the Security Documents except as specifically provided for in this
     Indenture and the Security Documents; or

          (10) make any change in the preceding amendment and waiver provisions.

Section 9.03 Compliance with Trust Indenture Act.

     Every amendment or supplement to this Indenture or the Notes will be set
forth in an amended or supplemental indenture that complies with the TIA as then
in effect.

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

Section 9.05 Notation on or Exchange of Notes.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee

                                       96

<PAGE>

shall, upon receipt of an Authentication Order, authenticate new Notes that
reflect the amendment, supplement or waiver.

     Failure to make the appropriate notation or issue a new Note will not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

     The Trustee will sign any amended or supplemental indenture authorized
pursuant to this Article 9 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 the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
will be entitled to receive and (subject to Section 7.01) will be fully
protected in relying upon, in addition to the documents required by Section
13.04, 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.

          (2)  the time of incurrence of any Series of Secured Debt within a
     Class;

          (3)  the order or method of attachment or perfection of any Liens
     securing any Series of Secured Debt within such Class;

          (4)  the time or order of filing or recording of financing statements,
     mortgages or other documents filed or recorded to perfect any Lien upon any
     Collateral;

          (5)  the time of taking possession or control over any Collateral; or

          (6)  the rules for determining priority under any law governing
     relative priorities of Liens:

     (a)  all Liens at any time granted by the Company or any Guarantor to
secure any of the Secured Debt within such Class will secure, equally and
ratably, all present and future Secured Obligations within such Class; and

     (b)  all proceeds of all Liens at any time granted by the Company or any
Guarantor to secure any of the Secured Debt and other Secured Obligations within
such Class will be allocated and distributed equally and ratably on account of
the Secured Debt and other Secured Obligations within such Class; provided, that
in the absence of an Event of Default, subject to the requirements set forth in
Sections 3.09 and 4.10, the Company and the Guarantors shall be entitled to
utilize cash proceeds of Collateral in the ordinary course of their business.

     The foregoing provision is intended for the benefit of, and will be
enforceable as a third party beneficiary by, each present and future holder of
Secured Obligations within the applicable Class, each

                                       97

present and future Secured Debt Representative therefor and the Collateral Agent
as holder of Secured Obligations within such Class. The Secured Debt
Representative of each future Series of Secured Debt within a Class will be
required to deliver a Sharing Confirmation to the Collateral Agent and the
Trustee at the time of incurrence of such Series of Secured Debt.

Section 10.02 Class Voting.

     With respect to any vote to be cast by the Trustee on behalf of the Holders
in accordance with Article 4 of the Collateral Trust Agreement, the Trustee will
vote all of such Notes as directed by the Holders of a majority in aggregate
principal amount of the outstanding principal amount of Notes. For purposes of
such direction to the Trustee, Notes registered in the name of, or Beneficially
Owned by, the Company or an Affiliate of the Company will be deemed not to be
outstanding.

Section 10.03 [Reserved]

Section 10.04 Relative Rights.

     Nothing in the Note Documents will:

          (1)  impair, as between the Company and the holders of the Notes, the
     obligation of the Company to pay principal of, premium and interest, if
     any, on the Notes in accordance with their terms or any other obligation of
     the Company or any other obligor under the Note Documents;

          (2)  affect the relative rights of holders of Notes as against any
     other creditors of the Company or any Guarantor (other than holders of
     other Secured Obligations);

          (3)  restrict the right of any holder of Notes to sue for payments
     that are then due and owing (but not enforce any judgment in respect
     thereof against any Collateral to the extent specifically prohibited by the

Notes or any other Note Obligations, and the right of the holders of the Notes

Liens on Collateral shall terminate and be discharged:

          (1)  upon satisfaction and discharge of this Indenture in accordance
     with Article 12;

          (3)  upon payment in full and discharge of all Notes and other Note
     Obligations that are outstanding under this Indenture, due and payable
     under this Indenture at the time those Notes are paid in full and

                              SUBSIDIARY GUARANTEES

Section 11.01 Guarantee.

     (a)  Subject to this Article 11 and the limitations set forth in Section
13.07, each of the Guarantors hereby, jointly and severally, unconditionally
guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, irrespective of the validity
and enforceability of this Indenture, the Notes or the obligations of the
Company hereunder or thereunder, that:

          (1)  the principal of, premium and Special Interest, if any, and
     interest on the Notes will be promptly paid in full when due, whether at
     maturity, by acceleration, redemption or Otherwise, and interest on the
     overdue principal of and interest and Special Interest, if any, on the
     Notes, if any, if lawful, and all other obligations of the Company to the
     Holders or the Trustee hereunder or thereunder will be promptly paid in
     full or performed, all in accordance with the terms hereof and thereof; and

          (2)  in case of any extension of time of payment or renewal of any
     Notes or any of such other obligations, that same will be promptly paid in
     full when due or performed in accordance with the terms of the extension or
     renewal, whether at stated maturity, by acceleration or otherwise.

     Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

     (b)  Subject to the limitations set forth in Section 13.07, the Guarantors
hereby agree that their obligations hereunder are unconditional, irrespective of
the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
of the Notes with respect to any provisions hereof or thereof, the recovery of
any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. Each Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands whatsoever and covenant that this
Subsidiary Guarantee will not be discharged except by complete performance of
the obligations contained in the Notes and this Indenture.

     (c)  If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company or the
Guarantors, any amount paid by either to the Trustee or such Holder, this
Subsidiary Guarantee, to the extent theretofore discharged, will be reinstated
in full force and effect.

                                       99

<PAGE>

     (d)  Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 for
the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6, such obligations (whether or not due
and payable) will forthwith become due and payable by the Guarantors for the
purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 11.02 Limitation on Guarantor Liability.

     Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Subsidiary
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance
for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree
that the obligations of such Guarantor will be limited to the maximum amount
that will, after giving effect to such maximum amount and all other contingent
and fixed liabilities of such Guarantor that are relevant under such laws, and
after giving effect to any collections from, rights to receive contribution from
or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under this Article 11, result in the
obligations of such Guarantor under its Subsidiary Guarantee not constituting a
fraudulent transfer or conveyance.

Section 11.03 Execution and Delivery of Subsidiary Guarantee.

     To evidence its Subsidiary Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Subsidiary Guarantee
substantially in the form attached as Exhibit F will be endorsed by an Officer
of such Guarantor on each Note authenticated and delivered by the Trustee and
that this Indenture will be executed on behalf of such Guarantor by one of its
Officers.

     Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in
Section 11.01 will remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Subsidiary Guarantee.

     If an Officer whose signature is on this Indenture or on the Subsidiary
Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will
be valid nevertheless.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in
this Indenture on behalf of the Guarantors.

     In the event that the Company creates or acquires any Subsidiary after the
Closing Date, if required by Section 4.21, the Company will cause such
Subsidiary to comply with the provisions of Section 4.21 and this Article 11, to
the extent applicable.

Section 11.04 Guarantors May Consolidate, etc., on Certain Terms.

     Except as otherwise provided in Section 11.05, no Guarantor may sell or
otherwise dispose of all or substantially all of its assets to, or consolidate
with or merge with or into (whether or not such Guarantor is the surviving
Person), another Person, other than the Company or another Guarantor, except as
permitted by Section 4.10.

     In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture in the form of
Exhibit G, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and
punctual performance of all of the covenants and conditions of this Indenture to
be performed by the Guarantor, such successor Person will succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed
any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee. All the Subsidiary Guarantees so issued will in
all respects have the same legal rank and benefit under this Indenture as the
Subsidiary Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all of such Subsidiary Guarantees had been
issued at the date of the execution hereof.

     Except as set forth in Articles 4 and 5, nothing contained in this
Indenture or in any of the Notes will prevent any consolidation or merger of a
Guarantor with or into the Company or another Guarantor, or will prevent any
sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety to the Company or another Guarantor.

Section 11.05 Releases Following Sale of Assets.

     In the event of any sale or other disposition of all or substantially all
of the assets of any Guarantor, by way of merger, consolidation or otherwise, or
a sale or other disposition of all of the Capital Stock of any Guarantor, in
each case to a Person that is not (either before or after giving effect to such
transactions) the Company or a Guarantor, then such Guarantor (in the event of a
sale or other disposition, by way of merger, consolidation or otherwise, of all
of the Capital Stock of such Guarantor) or the Person acquiring the property (in
the event of a sale or other disposition of all or substantially all of the
assets of such Guarantor) will be released and relieved of any obligations under
its Subsidiary Guarantee; provided,that the Net Proceeds of such sale or other
disposition are applied in accordance with the applicable provisions of this
Indenture, including without limitation Section 4.10. Upon delivery by the
Company to the Trustee of an Officer's Certificate and an Opinion of Counsel to
the effect that such sale or other disposition was made by the Company in
accordance with the provisions of this Indenture, including without limitation
Section 4.10, the Trustee will execute any documents reasonably required in
order to evidence the release of any Guarantor from its obligations under its
Subsidiary Guarantee.

     Any Guarantor not released from its obligations under its Subsidiary
Guarantee will remain liable for the full amount of principal of and interest
and premium and Special Interest, if any, on the Notes and for the other
obligations of any Guarantor under this Indenture as provided in this Article
11.

                           SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

     This Indenture will be discharged and will cease to be of further effect as
to all Notes issued hereunder, when:

          (1) either:

               (a)  all Notes that have been authenticated (except lost, stolen
     or destroyed Notes that have been replaced or paid and Notes for whose
     payment money has theretofore been deposited in trust and thereafter repaid
     to the Issuers) have been delivered to the Trustee for cancellation; or

               (b)  all Notes that have not been delivered to the Trustee for
     cancellation have become due and payable by reason of the mailing of a
     notice of redemption or otherwise or will become due and payable within one
     year and the Issuers have or any Guarantor has irrevocably deposited or
     caused to be deposited with the Trustee as trust funds in trust solely for
     the benefit of the Holders, cash in U.S. dollars, non-callable Government
     Securities, or a combination thereof, in such amounts as will be sufficient
     without consideration of any reinvestment of interest, to pay and discharge
     the entire indebtedness on the Notes not delivered to the Trustee for
     cancellation for principal, premium and Special Interest, if any, and
     accrued interest to the date of maturity or redemption;

          (2)  no Default or Event of Default has occurred and is continuing on
     the date of such deposit or will occur as a result of such deposit and such
     deposit will not result in a breach or violation of, or constitute a
     default under, any other instrument to which the Issuers are or any
     Guarantor is a party or by which the Issuers are or any Guarantor is bound;

          (3)  the Issuers have or any Guarantor has paid or caused to be paid
     all sums payable by it under this Indenture; and

          (4)  the Issuers have delivered irrevocable instructions to the
     Trustee under this Indenture to apply the deposited money toward the
     payment of the Notes at maturity or the redemption date, as the case may
     be.

In addition, the Issuers must deliver an Officer's Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

     Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section 12.01, the provisions of Section 12.02 and Section 8.06 will
survive. In addition, nothing in this Section 12.01 will be deemed to discharge
those provisions of Section 7.07, that, by their terms, survive the satisfaction
and discharge of this Indenture.

Section 12.02 Application of Trust Money.

     Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in
accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including either Issuer acting

                                      102

<PAGE>

as Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium and Special Interest, if any) and interest for
whose payment such money has been deposited with the Trustee; but such money
need not be segregated from other funds except to the extent required by law.

     If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with Section 12.01 by reason of any legal proceeding or
by reason of any order or judgment of any court or Governmental Authority
enjoining, restraining or otherwise prohibiting such application, the Company's
and any Guarantor's obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section
12.01; provided, that if the Issuers have made any payment of principal of,
premium or Special Interest, if any, or interest on any Notes because of the
reinstatement of its obligations, the Issuers shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or
Government Securities held by the Trustee or Paying Agent.

     The Company, any Guarantor or the Trustee, by notice to the others, may
designate additional or different addresses for subsequent notices or

     All notices and communications (other than those sent to Holders) will be
deemed to have been duly given: at the time delivered by hand, if personally
delivered; five Business Days after being deposited in the mail, postage
prepaid, if mailed; when receipt acknowledged, if sent by facsimile; and the

courier guaranteeing next day delivery.

     Any notice or communication to a Holder will be mailed by first class mail,
certified or registered, return receipt requested, or by overnight air courier
guaranteeing next day delivery to its address shown on the register kept by the
Registrar. Any notice or communication will also be so mailed to any Person
described in TIA Section 313(c), to the extent required by the TIA. Failure to
mail a notice or communication to a Holder or any defect in it will not affect
its sufficiency with respect to other Holders.

     If a notice or communication is mailed in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

     If the Company mails a notice or communication to Holders, it will mail a
copy to the Trustee and each Agent at the same time.

Section 13.03 Communication by Holders of Notes with Other Holders of Notes.

     Holders may communicate pursuant to TIA Section 312(b) with other Holders
with respect to their rights under this Indenture or the Notes. The Company, the
Trustee, the Registrar and anyone else shall have the protection of TIA Section
312(c).

Section 13.04 Certificate and Opinion as to Conditions Precedent.

     Upon any request or application by the Company to the Trustee to take any
action under this Indenture, the Company shall furnish to the Trustee:

          (1)  an Officer's Certificate in form and substance reasonably
     satisfactory to the Trustee (which must include the statements set forth in
     Section 13.05) stating that, in the opinion of the signers, all conditions
     precedent and covenants, if any, provided for in this Indenture relating to
     the proposed action have been satisfied; and

                                      104

<PAGE>

          (2)  an Opinion of Counsel in form and substance reasonably
     satisfactory to the Trustee (which must include the statements set forth in
     Section 13.05) stating that, in the opinion of such counsel, all such
     conditions precedent and covenants have been satisfied.

Section 13.05 Statements Required in Certificate or Opinion.

     Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (other than a certificate provided
pursuant to TIA Section 314(a)(4)) must comply with the provisions of TIA
Section 314(e) and must include:

          (1)  a statement that the Person making such certificate or opinion
     has read such covenant or condition;

          (2)  a brief statement as to the nature and scope of the examination
     or investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (3)  a statement that, in the opinion of such Person, he or she has
     made such examination or investigation as is necessary to enable him or her
     to express an informed opinion as to whether or not such covenant or
     condition has been satisfied; and

          (4)  a statement as to whether or not, in the opinion of such Person,
     such condition or covenant has been satisfied.

Section 13.06 Rules by Trustee and Agents.

     The Trustee may make reasonable rules for action by or at a meeting of
Holders. The Registrar or Paying Agent may make reasonable rules and set
reasonable requirements for its functions.

Section 13.07 Non-Recourse; No Personal Liability of Directors, Officers,
Employees and Stockholders.

     Notwithstanding anything to the contrary set forth in this Indenture, the
Notes, any Security Document or any other Note Document, the Notes and the
Subsidiary Guarantees are non-recourse secured obligations of the Company and
Guarantors, respectively. The only recourse a Holder will have with respect to
the payment of principal of, or interest or premium on, the Notes (whether under
the Indenture or the Notes, or pursuant to the Subsidiary Guarantees) will be
enforcement of its rights against CalGen Finance under this Indenture or against
the Collateral pursuant to the Security Documents. The Holders will have no
recourse to the equity or assets of the Excluded Subsidiary.

     No director, officer, employee, incorporator, stockholder, or partner of
the Company or any of its Subsidiaries, as such, will have any liability for any
obligations of the Issuers or any of its Subsidiaries under the Notes, this
Indenture, the Subsidiary Guarantees or the Security Documents, or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Notes by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.
The waiver may not be effective to waive liabilities under the federal
securities laws.

Section 13.08 Governing Law.

     THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO
CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES

                                      105

<PAGE>

WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

Section 13.09 No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret any other indenture, loan of
debt agreement of the Company or its Subsidiaries or of any other Person. Any
such indenture, loan or debt agreement may not be used to interpret this
Indenture.

their respective successors. All agreements of the Trustee in this Indenture
will bind its successors. All agreements of each Guarantor in this Indenture
will bind its successors, except as otherwise provided in Section 11.05.

provisions will not in any way be affected or impaired thereby.

Section 13.12 Counterpart Originals.

     The parties may sign any number of copies of this Indenture. Each signed

     October 1 of each year or, if any such day is not a Business Day, on the
     next succeeding Business Day (each, an "Interest Payment Date"). Interest
     on the Notes will accrue from the most recent date to which interest has
     been paid or, if no interest has been paid, from the date of issuance;
     provided, that if there is no existing Default in the payment of interest,
     and if this Note is authenticated between a record date referred to on the
     face hereof and the next succeeding Interest Payment Date, interest shall
     accrue from such next succeeding Interest Payment Date; provided, further,
     that the first Interest Payment Date will be July 1, 2004. The Issuers will
     pay interest (including post-petition interest in any proceeding under any
     Bankruptcy Law) on overdue principal and premium, if any, from time to time
     on demand at a rate that is 1% per annum in excess of the rate then in
     effect. The Issuers will pay interest (including post-petition interest in
     any proceeding under any Bankruptcy Law) on overdue installments of
     interest and Special Interest (without regard to any applicable grace
     periods) from time to time on demand at the same rate to the extent lawful.

     period, 375 basis points over the rate determined by the Company (notice of
     such rate to be sent to the Trustee by the Company on the date of
     determination thereof) equal to the greater of (x) 1.250% or (y) the

     Priority LIBOR Rate for the relevant interest period shall instead be the
     rate at which Morgan Stanley Senior Funding, Inc. or one of its affiliate
     banks offers to place deposits in U.S. dollars with first-class banks in
     the London interbank market for a period of one, two, three or six months
     (as applicable) as of approximately 11:00 a.m. (London time) two Business

<PAGE>

     appoint or maintain another entity as Registrar or Paying Agent, the
     Trustee shall act as such. The Company or any of its Subsidiaries may act
     as Paying Agent or Registrar. The Issuers initially appoint The Depository
     Trust Company to act as Depositary with respect to the Global Notes. The
     Issuers initially appoint the Trustee to act as the Registrar and Paying
     Agent and to act as Custodian with respect to the Global Notes.

     referred to the Indenture and such Act for a statement of .such terms. To
     the extent any provision of this Note conflicts with the express provisions
     of the Indenture, the provisions of the Indenture shall govern and be
     controlling. The Notes are secured obligations of the Company and CalGen
     Finance limited to $235.0 million in aggregate principal amount. The Notes
     are secured on a first-priority basis, Equally and Ratably with all other
     First Priority Lien Obligations, by (a) a security interest in all the
     assets of the Company and the Guarantors other than Excluded Assets, and
     (b) a pledge of the equity interests in the Company and CalGen Expansion
     Company, LLC, subject to Permitted Prior Liens.

     principal amount) set forth below plus accrued and unpaid interest and
     Special Interest, if any, on the Notes redeemed, to the applicable
     redemption date, if redeemed during the twelve-month period beginning on
     April 1 of the years indicated below, subject to the rights of the Holders
     on the relevant record date to receive interest on the relevant interest
     payment date:

<TABLE>
<CAPTION>
              Year                     Percentage

     interest will cease to accrue on the Notes or portions thereof called for
     redemption on the applicable redemption date.

     make an offer (a "Change of Control Offer") to each Holder to repurchase
     all or any part (equal to $1,000 or an integral multiple of $1,000) of such
     Holder's Notes at a purchase price in cash equal to 101% of the aggregate
     principal amount thereof plus accrued and unpaid interest and Special
     Interest, if any, on the Notes purchased, to, but excluding, the date of

     If the aggregate principal amount of Notes and other First Priority Lien
     Obligations tendered into such Asset Sale Offer (or required to be
     purchased, prepaid or redeemed) exceeds the amount of Net Proceeds
     available therefor, the Trustee will select the Notes and such other First
     Priority Lien Obligations to be purchased on a pro rata basis.

     least 30 days but not more than 60 days before the redemption date to each
     Holder whose Notes are to be redeemed at its registered address. Notes in

     purchase or tender offer or exchange offer for Notes) voting as a single
     class, and any existing default or compliance with any provision of the
     Indenture, the Subsidiary Guarantees or the Notes may be waived with the
     consent of the Holders of a majority in principal amount of the Notes then
     outstanding voting as a single class. Without the consent of any Holder,

     order to effect or maintain the qualification of the Indenture under the
     Trust Indenture Act, to make, complete or confirm any grant of Collateral

     or any of the Security Documents or any release of Collateral that becomes
     effective as set forth in the Indenture and the Security Documents, to
     conform the text of the Indenture, the Subsidiary Guarantees, the Security
     Documents or the Notes to any provision of the Description of Notes in the
     Offering Memorandum to the extent such provision of the Description of
     Notes in the Offering Memorandum was intended to be a verbatim recitation
     of a provision of the Indenture, the Subsidiary Guarantees, the Security
     Documents or the Notes, or to allow any Guarantor to execute a supplemental
     indenture in the form of Exhibit G to the Indenture and/or a Note Guarantee
     with respect to the Notes.

          (12) DEFAULTS AND REMEDIES. Events of Default include: (i) default for
     30 days in the payment when due of interest or Special Interest, if any, on
     any of the Notes; (ii) default in the payment when due of the principal of
     or premium, if any, on any of the Notes, (iii) failure by the Company or
     any of its Subsidiaries to comply with Section 3.09, 4.10, 4.15 or 4.19 of
     the Indenture; (iv) failure by the Company or any of its Subsidiaries to
     observe or perform any other agreement in the Indenture or the Security
     Documents for 30 days after notice to the Company by the Trustee or the
     Holders of at least 25% in aggregate principal amount of the Notes then
     outstanding voting as a single class; (v) default under certain other
     agreements relating to Indebtedness of the Company and its Subsidiaries
     which default is caused by the failure to pay principal of, or interest or
     premium, if any, on, such Indebtedness, or results in the acceleration of
     such Indebtedness prior to its express maturity; (vi) final judgments for
     the payment of money that remain undischarged for a period of 60 days,
     provided the aggregate amount of such judgments exceeds $25.0 million
     (excluding those covered by insurance); (vii) the repudiation of the
     Security Documents by the Company or a Guarantor or the unenforceability of
     the Security Documents under certain circumstances; (viii) except as
     permitted by the Indenture, any Subsidiary Guarantee shall be held in any
     judicial proceeding to be unenforceable or invalid or shall cease for any
     reason to be in full force and effect or any Guarantor or any Person acting
     on its behalf shall deny or disaffirm its obligations under such
     Guarantor's Subsidiary Guarantee; (ix) the breach by any Person (other than
     the Company and its Subsidiaries) of its obligations under, or the
     termination or failure to be in full force of, a Major Project Document,

     not be materially adverse to the Company and its Subsidiaries taken as a
     whole; and (x) certain events of bankruptcy or insolvency with respect to
     the Company or any of its Significant Subsidiaries. If any Event of Default
     occurs and is continuing, the Trustee or the Holders of at least 25% in
     aggregate principal amount of the then outstanding Notes may declare all
     the Notes to be due and payable. Notwithstanding the foregoing, in the case
     of an Event of Default arising from certain events of bankruptcy or
     insolvency, all outstanding Notes will become due and payable without
     further action or notice. Holders may not enforce the Indenture or the
     Notes except as provided in the Indenture and the Collateral Trust
     Agreement. Subject to certain limitations, Holders of a majority in
     principal amount of the then outstanding Notes may direct the Trustee in
     its exercise of any trust or power. The Trustee may withhold from Holders
     of the Notes notice of any continuing Default or Event of Default (except a
     Default or Event of Default relating to the payment of principal, interest
     or premium or Special Interest, if any) if it determines that withholding
     notice is in their interest. The Holders of a majority in aggregate
     principal amount of the Notes then outstanding by notice to the Trustee may
     on behalf of the Holders of all of the Notes waive any existing Default or
     Event of Default and its consequences under the Indenture except a
     continuing Default or Event of Default in the payment of principal of, or
     premium, if any, or interest or Special Interest, if any, on, the Notes.
     The Issuers are required to deliver to the Trustee annually a statement
     regarding compliance with the Indenture, and the Issuers are required upon
     becoming aware of any Default or Event of Default, to deliver to the
     Trustee a statement specifying such Default or Event of Default.

     any other capacity, may make loans to, accept deposits from, and perform
     services for the Company or its Affiliates, and may otherwise deal with the
     Company or its Affiliates, as if it were not the Trustee.

          (14) NO RECOURSE AGAINST OTHERS. A director, officer, employee,
     incorporator or stockholder of the Company or any Guarantor, as such, will

     under the Notes, the Subsidiary Guarantees or the Indenture or for any
     claim based on, in respect of, or by reason of, such obligations or their
     creation. Each Holder by accepting a Note waives and releases all such
     liability. This waiver and release are part of the consideration for the
     issuance of the Notes.

     representation is made as to the accuracy of such numbers either as printed

     Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

          (1)  INTEREST. Calpine Generating Company, LLC, a Delaware limited
     liability company (the "Company"), and CalGen Finance Corp., a Delaware
     corporation ("CalGen Finance" and, together with the Company, the
     "Issuers"), jointly and severally promise to pay interest on the principal
     amount of this Note at the Applicable First Priority LIBOR Rate (as defined
     below) per annum from March 23,2004 until maturity and will pay the Special
     Interest, if any, payable pursuant to the Registration Rights Agreement
     referred to below. The Issuers will pay interest and Special Interest, if
     any, semiannually in arrears on January 1, April 1, July 1 and October 1 of
     each year or, if any such day is not a Business Day, on the next succeeding
     Business Day (each, an "Interest Payment Date"). Interest on the Notes will
     accrue from the most recent date to which interest has been paid or, if no
     interest has been paid, from the date of issuance; provided, that if there
     is no existing Default in the payment of interest, and if this Note is
     authenticated between a record date referred to on the face hereof and the
     next succeeding Interest Payment Date, interest shall accrue from such next
     succeeding Interest Payment Date; provided, further, that the first
     Interest Payment Date will be July 1, 2004. The Issuers will pay interest
     (including post-petition interest in any proceeding under any Bankruptcy
     Law) on overdue principal and premium, if any, from time to time on demand
     at a rate that is 1% per annum in excess of the rate then in effect. The
     Issuers will pay interest (including post-petition interest in any
     proceeding under any Bankruptcy Law) on overdue installments of interest
     and Special Interest (without regard to any applicable grace periods) from
     time to time on demand at

                                   EXHIBIT B-3

<PAGE>

     the same rate to the extent lawful. Interest will be computed on the basis
     of a 360-day year of twelve 30-day months.

          "Applicable First Priority LIBOR Rate" means, for each interest
     period, 375 basis points over the rate determined by the Company (notice of
     such rate to be sent to the Trustee by the Company on the date of
     determination thereof) equal to the greater of (x) 1.250% or (y) the
     applicable British Bankers' Association LIBOR rate for deposits in U.S.
     dollars for a period of one, two, three or six months (as the Company may
     elect in an Officer's Certificate delivered to the Trustee as reported by
     any generally recognized financial information service as of 11:00 a.m.
     (London time) two Business Days prior to the first day of such interest
     period; provided, that, if no such British Bankers' Association LIBOR rate
     is available to the Company, the Applicable First Priority LIBOR Rate for
     the relevant interest period shall instead be the rate at which Morgan
     Stanley Senior Funding, Inc. or one of its affiliate banks offers to place
     deposits in U,S. dollars with first-class banks in the London interbank
     market for a period of one, two, three or six months (as applicable) as of
     approximately 11:00 a.m. (London time) two Business Days prior to the first
     day of such interest period, in amounts equal to $1.0 million.

          PRINCIPAL. The Issuers jointly and severally promise to pay principal
     of the Notes in quarterly installments, commencing July 1, 2007, as
     follows:

     The Issuers jointly and severally promise to pay all remaining principal
     of, interest and Special Interest, if any, on, and fees and costs in
     respect of the Notes on April 1, 2009.

     Until this Regulation S Temporary Global Note is exchanged for one or more
Regulation S Permanent Global Notes, the Holder hereof shall not be entitled to
receive payments of interest hereon; until so exchanged in full, this Regulation
S Temporary Global Note shall in all other respects be entitled to the same
benefits as other Notes under the Indenture.

          (2)  METHOD OF PAYMENT. The Company will pay interest on the Notes
     (except defaulted interest) and Special Interest, if any, to the Persons
     who are registered Holders of Notes at the close of business on the
     December 15, March 15, June 15 or September 15 immediately preceding the
     Interest Payment Date, even if such Notes are canceled after such record
     date and on or before such Interest Payment Date, except as provided in
     Section 2.12 of the Indenture with respect to defaulted interest. The Notes
     will be payable as to principal, premium, interest and Special Interest, if
     any, at the office or agency of the Company maintained for such purpose
     within or without the City and State of New York, or, at the option of the
     Company, payment of interest and Special Interest, if any, may be made by
     check mailed to the Holders at their addresses set forth in the register of
     Holders; provided, that payment by wire transfer of immediately available
     funds will be required with respect to principal of, and interest, premium

                                   EXHIBIT B-4

<PAGE>

     and Special Interest, if any, on, all Global Notes and all other Notes the
     Holders of which will have provided wire transfer instructions to the
     Company or the Paying Agent. Such payment will be in such coin or currency
     of the United States of America as at the time of payment is legal tender
     for payment of public and private debts.

          (3)  PAYING AGENT AND REGISTRAR. The Company, on behalf of itself and
     CalGen Finance, will maintain an office or agency where Notes may be
     presented for registration of transfer or for exchange ("Registrar") and an
     office or agency where Notes may be presented for payment ("Paying Agent").
     The Registrar will keep a register of the Notes and of their transfer and
     exchange. The Issuers 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
     Issuers may change any Paying Agent or Registrar without notice to any
     Holder. The Company will notify the Trustee in writing of the name and
     address of any Agent not a party to the Indenture. If the Issuers fail to
     appoint or maintain another entity as Registrar or Paying Agent, the
     Trustee shall act as such. The Company or any of its Subsidiaries may act
     as Paying Agent or Registrar. The Issuers initially appoint The Depository
     Trust Company to act as Depositary with respect to the Global Notes. The
     Issuers initially appoint the Trustee to act as the Registrar and Paying
     Agent and to act as Custodian with respect to the Global Notes.

          (4)  INDENTURE, The Company issued the Notes under a First Priority
     Indenture, dated as of March 23, 2004 (the "Indenture"), among the Issuers,
     the Guarantors and the Trustee. The terms of the Notes include those stated
     in the Indenture and those made part of the Indenture by reference to the
     Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
     77aaa-77bbbb). The Notes are subject to all such terms, and Holders are
     referred to the Indenture and such Act for a statement of such terms. To
     the extent any provision of this Note conflicts with the express provisions
     of the Indenture, the provisions of the Indenture shall govern and be
     controlling. The Notes are secured obligations of the Company and CalGen
     Finance limited to $235.0 million in aggregate principal amount. The Notes
     are secured on a first-priority basis, Equally and Ratably with all other
     First Priority Lien Obligations, by (a) a security interest in all the
     assets of the Company and the Guarantors other than Excluded Assets, and
     (b) a pledge of the equity interests in the Company and CalGen Expansion
     Company, LLC, subject to Permitted Prior Liens.

          (5)  OPTIONAL REDEMPTION. The Issuers may not redeem all or any part
     of the Notes prior to April 1, 2007. On or after April 1, 2007, the Issuers
     may redeem all or a part of the Notes, upon not less than 30 nor more than
     60 days prior notice, at the redemption prices (expressed at percentages of
     principal amount) set forth below plus accrued and unpaid interest and
     Special Interest, if any, on the Notes redeemed, to the applicable
     redemption date, if redeemed during the twelve-month period beginning on
     April 1 of the years indicated below, subject to the rights of the Holders
     on the relevant record date to receive interest on the relevant interest
     payment date:

<TABLE>
<CAPTION>
      Year                               Percentage
      ----                               ----------
<S>                                      <C>
2007                                       102.5%
2008, and thereafter                       100.0%
</TABLE>

          Unless the Company defaults in the payment of the redemption price,
     interest will cease to accrue on the Notes or portions thereof called for
     redemption on the applicable redemption date.

                                   EXHIBIT B-5

<PAGE>

          (6)  MANDATORY REDEMPTION. The Issuers will not be required to make
     mandatory redemption or sinking fund payments with respect to the Notes.

          (7)  REPURCHASE AT OPTION OF HOLDER.

               (a)  Upon the occurrence of a Change of Control, the Issuers will
     make an offer (a "Change of Control Offer") to each Holder to repurchase
     all or any part (equal to $1,000 or an integral multiple of $1,000) of such
     Holder's Notes at a purchase price in cash equal to 101% of the aggregate
     principal amount thereof plus accrued and unpaid interest and Special
     Interest, if any, on the Notes purchased, to, but excluding, the date of
     purchase, subject to the rights of Holders on the relevant record date to
     receive interest due on the relevant interest payment date. Within 30 days
     following any Change of Control, the Issuers will mail a notice to each
     Holder describing the transaction or transactions that constitute the
     Change of Control and stating the procedures governing the Change of
     Control Offer as required by Section 4.15 of the Indenture.

               (b)  The Issuers will be required to use the Net Proceeds from
     any Asset Sale, Casualty Event or Condemnation Event to offer to prepay
     Notes and other First Priority Lien Obligations (an "Asset Sale Offer").
     The offer price in any Asset Sale Offer will be equal to 100% of the
     principal amount plus accrued and unpaid interest and Special Interest, if
     any, on the Notes purchased, to, but excluding, the date of purchase, and
     will be payable in cash, subject to the rights of Holders on the relevant
     record date to receive interest due on the relevant interest payment date.
     If the aggregate principal amount of Notes and other First Priority Lien
     Obligations tendered into such Asset Sale Offer (or required to be
     purchased, prepaid or redeemed) exceeds the amount of Net Proceeds
     available therefor, the Trustee will select the Notes and such other First
     Priority Lien Obligations to be purchased on a pro rata basis.

          (8)  NOTICE OF REDEMPTION. Notice of redemption will be mailed at
     least 30 days but not more than 60 days before the redemption date to each
     Holder whose Notes are to be redeemed at its registered address. Notes in
     denominations larger than $1,000 may be redeemed in part but only in whole
     multiples of $1,000, unless all of the Notes held by a Holder are to be
     redeemed. On and after the redemption date interest ceases to accrue on
     Notes or portions thereof called for redemption.

          (9)  DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
     form without coupons in denominations of $1,000 and integral multiples
     thereof. The transfer of Notes may be registered and Notes may be exchanged
     as provided in the Indenture. The Registrar and the Trustee may require a
     Holder, among other things, to furnish appropriate endorsements and
     transfer documents and the Company may require a Holder to pay any taxes
     and fees required by law or permitted by the Indenture. The Company need
     not exchange or register the transfer of any Note or portion of a Note
     selected for redemption, except for the unredeemed portion of any Note
     being redeemed in part. Also, the Company need not exchange or register the
     transfer of any Notes for a period of 15 days before a selection of Notes
     to be redeemed or during the period between a record date and the
     corresponding Interest Payment Date.

     This Regulation S Temporary Global Note is exchangeable in whole or in part
for one or more Global Notes only (i) on or after the termination of the 40-day

     the Subsidiary Guarantees, the Security Documents or the Notes to any
     provision of the Description of Notes in the Offering Memorandum to the
     extent such provision of the Description of Notes in the Offering
     Memorandum was intended to be a verbatim recitation of a provision of the
     Indenture, the Subsidiary Guarantees, the Security Documents or the Notes,
     or to allow any Guarantor to execute a supplemental indenture in the form
     of Exhibit G to the Indenture and/or a Note Guarantee with respect to the
     Notes.

          (12) DEFAULTS AND REMEDIES. Events of Default include: (i) default for
     30 days in the payment when due of interest or Special Interest, if any, on

     outstanding voting as a single class; (v) default under certain other
     agreements relating to Indebtedness of the Company and its Subsidiaries
     which default is caused by the failure to pay principal of, or interest or
     premium, if any, on, such Indebtedness, or results in the acceleration of
     such Indebtedness prior to its express maturity; (vi) final judgments for
     the payment of money that remain undischarged for a period of 60 days,
     provided the aggregate amount of such judgments exceeds $25.0 million
     (excluding those covered by insurance); (vii) the repudiation of the
     Security Documents by the Company or a Guarantor or the unenforceability of
     the Security Documents under certain circumstances; (viii) except as
     permitted by the Indenture, any Subsidiary Guarantee shall be held in any
     judicial proceeding to be unenforceable or invalid or shall cease for any
     reason to be in full force and effect or any Guarantor or any Person acting
     on its behalf shall deny or disaffirm its obligations under such
     Guarantor's Subsidiary Guarantee; (ix) the breach by any Person (other than
     the Company and its Subsidiaries) of its obligations under, or the
     termination or failure to be in full force of, a Major Project Document,

     not be materially adverse to the Company and its Subsidiaries taken as a
     whole; and (x) certain events of bankruptcy or insolvency with respect to
     the Company or any of its Significant Subsidiaries. If any Event of

                                   EXHIBIT B-7

<PAGE>

     Default occurs and is continuing, the Trustee or the Holders of at least
     25% in aggregate principal amount of the then outstanding Notes may declare
     all the Notes to be due and payable. Notwithstanding the foregoing, in the
     case of an Event of Default arising from certain events of bankruptcy or
     insolvency, all outstanding Notes will become due and payable without
     further action or notice. Holders may not enforce the Indenture or the
     Notes except as provided in the Indenture and the Collateral Trust
     Agreement. Subject to certain limitations, Holders of a majority in
     principal amount of the then outstanding Notes may direct the Trustee in
     its exercise of any trust or power. The Trustee may withhold from Holders
     of the Notes notice of any continuing Default or Event of Default (except a
     Default or Event of Default relating to the payment of principal, interest
     or premium or Special Interest, if any) if it determines that withholding
     notice is in their interest. The Holders of a majority in aggregate
     principal amount of the Notes then outstanding by notice to the Trustee may
     on behalf of the Holders of all of the Notes waive any existing Default or
     Event of Default and its consequences under the Indenture except a
     continuing Default or Event of Default in the payment of principal of, or
     premium, if any, or interest or Special Interest, if any, on, the Notes.
     The Issuers are required to deliver to the Trustee annually a statement
     regarding compliance with the Indenture, and the Issuers are required upon
     becoming aware of any Default or Event of Default, to deliver to the
     Trustee a statement specifying such Default or Event of Default.

          (13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
     any other capacity, may make loans to, accept deposits from, and perform
     services for the Company or its Affiliates, and may otherwise deal with the
     Company or its Affiliates, as if it were not the Trustee.

          (14) NO RECOURSE AGAINST OTHERS. A director, officer, employee,
     incorporator or stockholder of the Company or any Guarantor, as such, will
     not have any liability for any obligations of the Company or such Guarantor
     under the Notes, the Subsidiary Guarantees or the Indenture or for any
     claim based on, in respect of, or by reason of, such obligations or their
     creation. Each Holder by accepting a Note waives and releases all such
     liability. This waiver and release are part of the consideration for the
     issuance of the Notes.

          (15) AUTHENTICATION. This Note will not be valid until authenticated
     by the manual signature of the Trustee or an authenticating agent,

          (16) ABBREVIATIONS. Customary abbreviations may be used in the name of
     a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
     tenants by the entireties), JT TEN (= joint tenants with right of
     survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
     (= Uniform Gifts to Minors Act).

          (17) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
     RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders
     of Notes under the Indenture, Holders of Restricted Global Notes and
     Restricted Definitive Notes will have all the rights set forth in the
     Registration Rights Agreement, dated as of March 23,2004 (the "Registration
     Rights Agreement"), among the Company, CalGen Finance, the Guarantors and
     the initial purchaser of the Notes.

          (18) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
     Committee on Uniform Security Identification Procedures, the Company has
     caused CUSIP numbers to be printed on the Notes and the Trustee may use
     CUSIP numbers in notices of redemption as a convenience to Holders. No
     representation is made as to the accuracy of such numbers either as

                                   EXHIBIT B-8

<PAGE>

     printed on the Notes or as contained in any notice of redemption and
     reliance may be placed only on the other identification numbers placed
     thereon,

          (19) NON-RECOURSE. Notwithstanding anything to the contrary set forth
     in the Indenture, this Note, any Security Document or any other Note
     Document, this Note and the Subsidiary Guarantees are non-recourse secured
     obligations of the Company and Guarantors, respectively. The only recourse
     a holder of the Notes will have with respect to the payment of principal
     of, or interest or premium or Special Interest, if any, on, this Note
     (whether under the Indenture or the Note, or pursuant to the Subsidiary
     Guarantees) will be enforcement of its rights against CalGen Finance under
     the Indenture or against the Collateral pursuant to the Security Documents.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture, the Registration Rights Agreement and the
Security Documents. Requests may be made to:

                         [FORM OF SUPPLEMENTAL INDENTURE
                    TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

     SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as
of__________________________ 20___, among_______________________, a_______ (the
"'Guaranteeing Subsidiary"), Calpine Generating Company, LLC (the "Company"),
CalGen Finance Corp. ("CalGen Finance" and, together with the Company, the
"Issuers"), the other Guarantors (as defined in the Indenture referred to
herein) and Wilmington Trust FSB, as trustee under the Indenture referred to
herein (the "Trustee").

                                   WITNESSETH

     WHEREAS, the Issuers have heretofore executed and delivered to the Trustee
a First Priority Indenture, dated as of March 23, 2004 (the "Indenture"),
providing for the issuance of an aggregate principal amount of $235.0 million of
First Priority Secured Floating Rate Notes due 2009 (the "Notes");

     WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Subsidiary Guarantee"); and

     WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

     1.   CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

     2.   AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to
provide an unconditional Guarantee on the terms and subject to the conditions
set forth in the Note Guarantee and in the Indenture, including but not limited
to Article 11 thereof, and to become bound as a "Guarantor" under the Indenture.

     3.   NO RECOURSE AGAINST OTHERS. This Subsidiary Guarantee is a
non-recourse secured obligation of the Subsidiary Guarantor. The only recourse a
Holder of Notes will have under the Subsidiary Guarantee is enforcement of its
rights against the Collateral securing the Subsidiary Guarantee pursuant to the
Security Documents. No past, present or future director, officer, employee,
incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such,
shall have any liability for any obligations of the Company or any Guaranteeing
Subsidiary under the Notes, any Subsidiary Guarantee, the Indenture or this
Supplemental Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of the Notes by accepting a
Note waives and releases all such liability. This waiver and release are part of
the consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
SEC that such a waiver is against public policy.

     4.   NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO

Supplemental Indenture. Each signed copy shall he an original, but all of them
together represent the same agreement.

     6.   EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

     7.   THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by the Guaranteeing Subsidiary and the Company.

Claimant shall take any action prejudicial to or inconsistent with the Senior
Claimants' priority position over Junior Claimant created by this Article,
including, without limitation, any action which will hinder, delay or otherwise
prevent the Senior Claimants from taking any action they deem necessary to
enforce rights with respect to the Senior Claims or the Lien of the Senior Claim
Documents. The Junior Claimant shall not take any action or otherwise act to
contest on account of the Subordinated Debt (i) the validity or priority of any
Liens or security interests granted to, or for the benefit of, the Senior
Claimants, (ii) the relevant rights and duties of the Senior Claimants with
respect to Junior Claimant on account of any Subordinated Debt as established in
this Article or (iii) the Senior Claimants' exercise of remedies in accordance
with the Senior Claim Documents.

                    [____].2.4. Each document or instrument evidencing
Subordinated Debt shall bear a legend providing that payment of the Subordinated
Debt thereunder, has been subordinated to prior payment of the Senior Claims in
the manner and to the extent set forth in this Article.

                    [____].2.5. Junior Claimant shall not commence or join with
any other creditor or creditors of the Subordinated Debtor in commencing any
Proceeding against the Subordinated Debtor, [CalGen, CalGen Holdings or any
Guarantor--ADD ALL THAT ARE NOT SUBORDINATED DEBTORS], but may join in any
Proceeding after it has commenced. At any general meeting of creditors of
Subordinated Debtor, [CalGen, CalGen Holdings or any Guarantor--ADD ALL THAT
ARE NOT SUBORDINATED DEBTORS], or in the event of any Proceeding, if all Senior
Claims have not been paid in full in cash at such time, the Collateral Agent on
behalf of the Senior Claimants is hereby irrevocably authorized at any such
meeting or in any such Proceeding:

                    (a)  To enforce claims comprising Subordinated Debt in the
          name of Junior Claimant, by proof of debt, proof of claim, suit or
          otherwise;

                    (b)  To collect any assets of the Subordinated Debtor
          distributed, divided or applied by way of dividend or payment as a
          result of a Proceeding, or such securities issued, on account of
          Subordinated Debt as a result thereof and apply the same, or the
          proceeds of any realization upon the same that the Senior Claimants in
          their discretion elect to effect, to Senior Claims until all Senior
          Claims shall have been paid in full in cash (the Senior Claimants
          hereby agreeing to render any surplus to Junior Claimant and/or other
          subordinated creditors, as their interests appear, or to interplead
          such surplus with a court of competent jurisdiction); and

                    (c)  To take generally any action in connection with any
          such meeting or proceeding which Junior Claimant might otherwise take
          in respect of the Subordinated Debt and claims relating thereto.

                    After the commencement of any such Proceeding, Junior
Claimant may inquire in writing of the Collateral Agent on behalf of the Senior
Claimants whether the respective Senior Claimants intend to exercise the
foregoing rights with respect to the Subordinated Debt. Should the Senior
Claimants fail, at least 20 days before the deadline therefor, either to file a
proof of claim with respect to the Subordinated Debt and to furnish a copy
thereof to Junior Claimant, or to inform Junior Claimant in writing that the
Senior Claimants intend to exercise their rights to assert the Subordinated Debt
in the manner hereinabove provided, Junior Claimant may, but shall not be
required to, proceed to file a proof of claim with respect to the Subordinated
Debt and take such further steps with respect thereto, not inconsistent with
this Article, as Junior Claimant may deem proper.

                    [____].2.6. Upon the occurrence and during the continuation
of an event of default under a Secured Debt Document, Junior Claimant may, but
shall have no obligation to, upon not less than 10 days prior written notice to
the Collateral Agent, purchase all of the outstanding Senior Obligations owing
to the Senior Claimants by irrevocably tendering, in immediately available
funds, full payment of the Purchase Price (as defined below) to the Senior
Claimants:

                    (a)  The Purchase Price shall be equal to the total amount
          of Senior Claims at the time of acceleration (assuming such
          obligations have been accelerated);

                                   EXHIBIT H-3

<PAGE>

                    (b)  Any such purchase by Junior Claimant shall be without
          warranty by, or recourse to, the Senior Claimants, except with respect
          to the legal and beneficial ownership by the Senior Claimants of the
          Obligations so purchased, free and clear of all Liens and rights of
          others; and

                    (c)  Concurrently with any such purchase, the Senior
          Claimants shall forthwith sell, assign, transfer and convey to Junior
          Claimant all of their right, title and interest in and to the Senior
          Obligations, and all Liens and other security interests in favor of
          the Senior Claimants securing the obligations of the Subordinated
          Debtor in connection therewith.

          Section [____].3. Senior Claim Documents. The Junior Claimant
acknowledges that it has been provided with a copy of the Senior Claim Documents
and has read and is familiar with the provisions thereof.

          Section [____].4. Time of Filing. Notwithstanding the time of filing,
attachment or recording of any document or other instrument, it is agreed by
Junior Claimant that any Liens arising under or pursuant to the Senior Claim
Documents shall be senior to any Liens arising in favor of Junior Claimant as
part of or relating to the Subordinated Debt Documents, if any; provided,
however, that nothing herein shall be deemed to permit Junior Claimant to obtain
any such Liens.

          Section [____].5. Wrongful Collections. Should any payment on account
of, or any collateral for any part of, the Subordinated Debt be received by
Junior Claimant in violation of this Article, such payment or collateral shall
be delivered forthwith to the Collateral Agent by the recipient for application
to Senior Claims, in the form received. The Collateral Agent is irrevocably
authorized to supply any required endorsement or assignment which may have been
omitted. Until so delivered, any such payment or collateral shall be held by the
recipient in trust for the Senior Claimants and shall not be commingled with
other funds or property of the recipient.

          Section [____].6. Ownership of Subordinated Debt;' Amendment of
Subordinated Debt Documents.

                    [____].6.1. The Junior Claimant represents and warrants that
it is the lawful owner of the Subordinated Debt. Any security interest in the
Junior Claimant's interest in the Subordinated Debt will at all times be subject
to the rights of the Senior Claimants hereunder. The Junior Claimant agrees that
it may not assign all or any portion of the Subordinated Debt or any of its
rights or remedies under the Subordinated Debt Documents unless any assignee
expressly agrees in writing for the benefit of the Collateral Agent that it
takes such Subordinated Debt subject in all respects to the rights of the Senior
Claimants hereunder.

                    [____].6.2. The Subordinated Debt Documents may not be
amended so as to have an adverse effect upon the Senior Claims or the
Subordinated Debtor's ability to pay the Senior Claims at any time.

          Section [____].7. Waivers. The Collateral Agent and the Senior
Claimants are hereby authorized to demand specific performance of this Article,
whether or not the Subordinated Debtor shall have complied with the provisions
hereof applicable to it, at any time when Junior Claimant shall have failed to
comply with any provision hereof applicable to it. Junior Claimant hereby
irrevocably waives any defense based on the adequacy of a remedy at law which
might be asserted as a bar to the remedy of specific performance hereof in any
action brought therefor by the Senior Claimants. Junior Claimant (a) further
waives presentment, notice and protest in connection with all negotiable
instruments

evidencing Senior Claims or Subordinated Debt to which Junior Claimant may be a
party, notice of the acceptance of this Article by the Senior Claimants, notice
of any loan made, extension granted or other action taken in reliance hereon,
and all demands and notices of every kind in connection with this Article,
Senior Claims or time of payment of Senior Claims or Subordinated Debt and (b)
hereby assents to any renewal, extension or postponement of the time of payment
of Senior Claims or any other indulgence with respect thereto, to any increase
in the amount of Senior Claims, to any substitution, exchange or release of
collateral therefor and to the addition or release of any person primarily or
secondarily liable thereon and assents to the provisions of any instrument,
security or other writing evidencing Senior Claims.

          Section [____].8. Subrogation; No Impairment of Subordinated Debtor's
Obligations. Subject to and from and after the Senior Obligations Termination
Date, Junior Claimant shall be subrogated to the rights of the Senior Claimants
to receive payments or distributions of cash, property or securities of the
Subordinated Debtor applicable to the Senior Claims until all amounts owing on
the Subordinated Debt shall be paid in full. For purposes of such subrogation,
no payments or distributions to the Senior Claimants to which Junior Claimant
would be entitled but for the provisions of this Article, and no payments paid
over by Junior Claimant to Senior Claimants pursuant to this Article shall, as
among the Subordinated Debtor, its creditors other than the Senior Claimants,
and Junior Claimant, be deemed to be a payment or distribution on account of the
Subordinated Debt, it being understood that the provisions of this Article are
intended solely for the purpose of defining the relative rights of Junior
Claimant and the Senior Claimants. Nothing contained in this Article is intended
to or shall impair, as between the Subordinated Debtor and Junior Claimant, the
obligation of the Subordinated Debtor, which is absolute and unconditional, to
pay to Junior Claimant the principal of and the premium, if any, and the
interest on the Subordinated Debt, and all other amounts payable by the
Subordinated Debtor under the Subordinated Debt Documents, as and when the same
shall become due and payable, or to affect the relative rights of Junior
Claimant and creditors of Subordinated Debtor other than the Senior Claimants.

          Section [____].9. Reinstatement. The obligations of Junior Claimant
under this Article shall continue to be effective, or be reinstated, as the case
may be, if at any time any payment in respect of any Senior Claim, or any other
payment to any holder of any Senior Claim in its capacity as such, is rescinded
or must otherwise be restored or returned by the holder of such Senior Claims
upon the occurrence of any Proceeding, or upon or as a result of the appointment
of a receiver, intervenor or conservator of, or trustee or similar officer for,
the Subordinated Debtor or any substantial part of its property, or otherwise,
all as though such payment had not been made.

          Section [____].10. Bankruptcy. This Article shall remain in full force
and effect as between Junior Claimant and the Senior Claimants notwithstanding
the occurrence of any Proceeding affecting the Subordinated Debtor.

          Section [____].11. Further Assurances. The Subordinated Debtor and
Junior Claimant shall execute and deliver to the Senior Claimants such further
instruments and shall take such further action as the Senior Claimants may at
any time or times reasonably request in order to carry out the provisions and
intent of this Article.

          Section [____].12. Successors and Assigns. The provisions of this
Article shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns. Neither Junior Claimant nor the Senior
Claimants shall have a duty to preserve rights against prior parties in any
property of any kind received hereunder. Nothing contained herein shall impose
on the Senior Claimants any duties with respect to any property of the
Subordinated Debtor or Junior Claimant received hereunder.

          Section [____].13. Governing Law. This Article is intended to take
effect as a sealed instrument, shall be binding upon the parties hereto and
their respective executors, administrators, other legal representatives,
successors and assigns, and shall inure to the benefit of the Senior Claimants,
their respective successors and assigns and shall be governed by the laws of the
State of New York without reference to principles of conflict of laws (other
than Section 5-1401 of the New York General Obligations Law). The parties hereto
intend and agree that this Article shall remain binding on such parties (other
than the Subordinated Debtor) notwithstanding the termination (except upon the
payment in full of Senior Claims in cash) or unenforceability of this Article as
against the Debtor.

Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage. Each Note will be dated the date of its authentication.
The Notes shall be in denominations of $1,000 and integral multiples thereof.

      The terms and provisions contained in the Notes will constitute, and are
hereby expressly made, a part of this Indenture and the Issuers and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby. However, to the extent any provision of

by Section 2.06.

copies of certificates from Euroclear and Clearstream, certifying that they have
received certification of non-United States beneficial ownership of 100% of the
aggregate principal amount of the Regulation S Temporary Global Note (except to
the extent of any beneficial owners thereof who acquired an interest therein
during the Restricted Period pursuant to another exemption from registration
under the Securities Act and who will take delivery of a beneficial ownership
interest in a 144A Global Note or an LAI Global Note bearing a Private Placement

may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depositary or its nominee, as the case may be, in
connection with transfers of interest as hereinafter provided.

      (d) Eurodear and Clearstream Procedures Applicable. The provisions of the
"Operating Procedures of the Euroclear System" and "Terms and Conditions

Banking" and "Customer Handbook" of Clearstream will be applicable to transfers
of beneficial interests in the Regulation S Temporary Global Note and the
Regulation S Permanent Global Notes that are held by Participants through
Euroclear or Clearsteam.

Section 2.02 Execution and Authentication.

      One Officer of each Issuer must sign the Notes for the Issuers by manual
or facsimile signature.

      If an Officer whose signature is on a Note no longer holds that office at
the time a Note is authenticated, the Note will nevertheless be valid.

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

      The Trustee will, upon receipt of a written order of the Issuers signed by
one Officer of each Issuer (an "Authentication Order"), authenticate Notes for
original issue up to the aggregate principal amount stated in paragraph 4 of the
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed such amount except as provided in Section 2.07.

      The Trustee may appoint an authenticating agent acceptable to the Issuers
to authenticate Notes. An authenticating agent may authenticate 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 Holders or an Affiliate of the Issuers.

Section 2.03 Registrar and Paying Agent.

      The Company, on behalf of itself and CalGen Finance, will maintain an
office or agency where Notes may be presented for registration of transfer or
for exchange ("Registrar") and an office or agency where Notes may be presented
for payment ("Paying Agent"). The Registrar will keep a register of the Notes
and of their transfer and exchange. The Issuers 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 Issuers may change any Paying Agent or Registrar without
notice to any Holder. The Company will notify the Trustee in writing of the name
and address of any Agent not a parry to this Indenture. If the Issuers fail to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such. The Company or any of its Subsidiaries may act as Paying
Agent or Registrar.

      The Issuers initially appoint The Depository Trust Company ("DTC") to act
as Depositary with respect to the Global Notes.

                                       45

<PAGE>

      The Issuers initially appoint the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

      The Issuers will require each Paying Agent other than the Trustee 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, interest or Special Interest, if any, on, the Notes, and
will notify the Trustee of any default by the Issuers 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 by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) will have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it will 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 will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

      The Trustee will 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 will 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 and the
Company shall otherwise comply with TIA Section 312(a).

Section 2.06 Transfer and Exchange.

      (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. A Global Note will be exchangeable by
the Issuers for Definitive Notes if:

            (1) the Issuers deliver to the Trustee written notice from the
      Depositary that it is unwilling or unable to continue to act as Depositary
      or that it is no longer a clearing agency registered under the Exchange
      Act and, in either case, a successor Depositary is not appointed by the
      Issuers within 120 days after the date of such notice from the Depositary;

            (2) the Issuers in their sole discretion determine that the Global
      Notes (in whole but not in part) should be exchanged for Definitive Notes
      and deliver a written notice to such effect to the Trustee; provided, that
      in no event shall the Regulation S Temporary Global Note be exchanged by
      the Issuers for Definitive Notes prior to (x) the expiration of the
      Restricted Period and (y) the receipt by the Registrar of any certificates
      required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

                        (i) if the Holder of such Restricted Definitive Note
                  proposes to exchange such Note for an Unrestricted Definitive

<PAGE>

                        (ii) if the Holder of such Restricted Definitive Note
                  proposes to transfer such Note to a Person who shall take
                  delivery thereof in the form of an Unrestricted Definitive
                  Note, a certificate from such Holder in the form of Exhibit C,
                  including the certifications in item (4) thereof;

            and, in each such case set forth in this subparagraph (D), if the
            Registrar so requests, an Opinion of Counsel in form reasonably
            acceptable to the Company to the effect that such exchange or
            transfer is in compliance with the Securities Act and that the
            restrictions on transfer contained herein and in the Private
            Placement Legend are no longer required in order to maintain
            compliance with the Securities Act.

            (3) Unrestricted Definitive Notes to Unrestricted Definitive Notes.
      A Holder of Unrestricted Definitive Notes may transfer such Notes to a

      amount equal to the principal amount of the beneficial interests in the

      Persons that certify in the applicable Letters of Transmittal that (A)
      they are not Broker-Dealers, (B) they are not participating in a

      (B) they are not participating in a distribution of the Exchange Notes and
      (C) they are not affiliates (as defined in Rule 144) of the Company.

      Concurrently with the issuance of such Notes, the Trustee will cause the
aggregate principal amount of the applicable Restricted Global Notes to be
reduced accordingly, and the Company will execute and the Trustee, upon receipt
of an Authentication Order, will authenticate and deliver to the Persons

      (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note will be returned to or
retained and canceled by the Trustee in accordance with Section 2.11. At any
time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note or for Definitive Notes,
the principal amount of Notes represented by such Global Note will be reduced
accordingly and an endorsement will be made on such Global Note by the Trustee

      (i) General Provisions Relating to Transfers and Exchanges.

            (1) To permit registrations of transfers and exchanges, the Issuers
      will execute and the Trustee will authenticate Global Notes and Definitive
      Notes upon receipt of an Authentication Order in accordance with Section
      2.02 or at the Registrar's request.

            (2) No service charge will be made to a Holder of a Global Note or
      to a Holder of a Definitive Note for any registration of transfer or
      exchange, but the Issuers may require payment of a sum sufficient to cover
      any transfer tax or similar governmental charge payable in connection
      therewith (other than any such transfer taxes or similar governmental
      charge payable upon exchange or transfer pursuant to Sections
      2.10,3.06,3.09,4.10,4.15 and 9.05).

            (3) The Registrar will not be required to register the transfer of
      or exchange any Note selected for redemption in whole or in part, except
      the unredeemed portion of any Note being redeemed in part.

            (4) All Global Notes and Definitive Notes issued upon any
      registration of transfer or exchange of Global Notes or Definitive Notes
      will be the valid obligations of the Issuers, evidencing the same debt,
      and entitled to the same benefits under this Indenture, as the Global
      Notes or Definitive Notes surrendered upon such registration of transfer
      or exchange.

            (5) The Issuers will not be required:

                  (A) to issue, to register the transfer of or to exchange any
            Notes during a period beginning at the opening of business 15 days
            before the day of any selection of Notes for redemption under
            Section 3.02 and ending at the close of business on the day of
            selection;

                  (B) to register the transfer of or to exchange any Note
            selected for redemption in whole or in part, except the unredeemed
            portion of any Note being redeemed in part; or

                  (C) to register the transfer of or to exchange a Note between
            a record date and the next succeeding interest payment date,

            (6) Prior to due presentment for the registration of a transfer of
      any Note, the Trustee, any Agent and the Issuers may deem and treat the
      Person in whose name any Note is registered as the absolute owner of such
      Note for the purpose of receiving payment of principal of and interest on
      such Note and for all other purposes, and none of the Trustee, any Agent,
      the Company or CalGen Finance shall be affected by notice to the contrary.

Section 2.07 Replacement Notes.

      If any mutilated Note is surrendered to the Trustee or the Issuers and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Issuers will issue and the Trustee, upon receipt of an
Authentication Order, will authenticate a replacement Note if the Trustee's
requirements hereunder are met. If required by the Trustee or either Issuer, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent
and any authenticating agent from any loss that any of them may suffer if a Note
is replaced. The Issuers may charge the applicable Holder for their expenses in
replacing a Note.

      Every replacement Note is an additional obligation of the Issuers and will
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

      The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions hereof, and those described in this Section as
not outstanding. Except as set forth in Section 2.09, a Note does not cease to
be outstanding because the Company or an Affiliate of the Company holds the
Note.

      If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected purchaser.

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

      If the Paying Agent (other than the Company, a Subsidiary of the Company
or an Affiliate of any thereof) holds, on a redemption date or maturity date,
money sufficient to pay Notes payable on that date, then on and after that date
such Notes will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.09 Treasury Notes,

      In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, will be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee will be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

      Until certificates representing Notes are ready for delivery, the Issuers
may prepare and the Trustee, upon receipt of an Authentication Order, will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of certificated Notes but may have variations that the Issuers consider
appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee
will authenticate definitive Notes in exchange for temporary Notes.

      Holders of temporary Notes will be entitled to all of the benefits of this
Indenture.

                                       59

<PAGE>

Section 2.11 Cancellation.

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

Section 2.12 Defaulted Interest.

      If the Company defaults in a payment of interest on the Notes, it will pay
the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01. The Company will notify the Trustee in writing of the
amount of defaulted interest proposed to be paid on each Note and the date of
the proposed payment. The Company will fix or cause to be fixed each such
special record date and payment date, provided, that no such special record date
may be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) will mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

Section 2.13 Same Day Settlement and Payment.

      The Issuers will make payments in respect of the Notes represented by the
Global Notes (including principal, premium, if any, and interest and Special
Interest, if any) by wire transfer of immediately available funds to the
accounts specified by the Holder of the Global Note. The Issuers will make all
payments of principal, interest and premium and Special Interest, if any, with
respect to Definitive Notes by wire transfer of immediately available funds to
the accounts specified by the Holders of the Definitive Notes or, if no such
account is specified, by mailing a check to each such Holder's registered
address.

      Because of time zone differences, the securities account of a Euroclear or
Clearstream participant purchasing an interest in a Global Note from a
Participant in DTC will be credited, and any such crediting will be reported to
the relevant Euroclear or Clearstream participant, during the securities
settlement processing day (which must be a business day for Euroclear and
Clearstream) immediately following the settlement date of DTC. DTC has advised
the Issuers that cash received in Euroclear or Clearstream as a result of sales
of interests in a Global Note by or through a Euroclear or Clearstream
participant to a Participant in DTC will be received with value on the
settlement date of DTC but will be available in the relevant Euroclear or
Clearstream cash account only as of the business day for Euroclear or
Clearstream following DTC's settlement date.

                            REDEMPTION AND PREPAYMENT

      If the Company elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 30
days hut not more than 60 days before a redemption date, an Officer's
Certificate setting forth:

            (1) the clause of this Indenture pursuant to which the redemption
      shall occur;

            (3) the principal amount of Notes to be redeemed; and

            (4) the redemption price.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

      If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee will select Notes for redemption or
purchase on a pro rata basis except:

            (1) if the Notes are listed on any national securities exchange, in
      compliance with the requirements of the principal national securities
      exchange on which the Notes are listed; or

            (2) if otherwise required by law.

      In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased will be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption or
purchase date by the Trustee from the outstanding Notes not previously called
for redemption or purchase.

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

Section 3.03 Notice of Redemption.

      Subject to the provisions of Section 3.09, at least 30 days but not more
than 60 days before a redemption date, the Company will mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address, except that redemption notices may
be mailed more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture pursuant to Article 8 or 12 of this Indenture. Notices of
redemption may not be conditional.

      The notice will identify the Note(s) to be redeemed and will state:

            (1) the redemption date;

            (2) the redemption price;

                                       61

<PAGE>

            (3) if any Note is to be redeemed in part only, the portion of the
      principal amount of such Note to be redeemed and that, after the
      redemption date upon surrender of such Note, a new Note or Notes in
      principal amount equal to the unredeemed portion will be issued upon
      cancellation of the original Note;

            (4) the name and address of the Paying Agent;

            (5) that Notes called for redemption must be surrendered to the
      Paying Agent to collect the redemption price;

            (6) that, unless the Issuers default in making such redemption
      payment, interest on Notes called for redemption ceases to accrue on and
      after the redemption date;

            (7) the paragraph of the Notes and/or Section of this Indenture
      pursuant to which the Notes called for redemption are being redeemed; and

            (8) 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
      Notes.

      At the Company's request, the Trustee will give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
has delivered to the Trustee, at least 45 days prior to the redemption date, an
Officer's 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, 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 or Purchase Price.

      Not less than one Business Day prior to the redemption or purchase price
date, the Issuers will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued interest and
Special Interest, if any, on all Notes to be redeemed or purchased on that date.
The Trustee or the Paying Agent will promptly return to the Issuers any money
deposited with the Trustee or the Paying Agent by the Issuers in excess of the
amounts necessary to pay the redemption or purchase price of, and accrued
interest and Special Interest, if any, on, all Notes to be redeemed or
purchased.

      If the Issuers comply with the provisions of the preceding paragraph, on
and after the redemption or purchase date, interest will cease to accrue on the
Notes or the portions of Notes called for redemption or purchase. If a Note is
redeemed or purchased 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. If any Note called for redemption or purchase is not so paid upon

      accrue interest after the Purchase Date;

      not later than two Business Days before the Purchase Date, a facsimile
      transmission or letter setting forth the name of the Holder, the principal
      amount of the Note the Holder delivered for purchase and a statement that

      Second Priority Lien Obligations tendered in the Asset Sale Offer (or
      required to be purchased, prepaid or redeemed) exceeds the Offer Amount,
      the Company will select the Notes and other Second Priority Lien
      Obligations to be purchased, prepaid or redeemed on a pro rata basis based
      on the principal amount of Notes and such other Second Priority Lien
      Obligations tendered (or required to be purchased, prepaid or redeemed),
      with such adjustments as may be deemed appropriate by the Company so that
      only Notes in denominations of $1,000, or integral multiples thereof, will
      be purchased, prepaid or redeemed; and

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

      On or before the Purchase Date, the Issuers will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer

thereof were accepted for payment by the Issuers in accordance with the terms of
this Section 3.09. Payment for any Notes so purchased will be made in the same
manner as interest payments are made. The Issuers, the Depositary or the Paying
Agent, as the case may be, will 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 Notes tendered by such Holder and accepted by
the Issuers for purchase, and the Issuers will promptly issue a new Note, and
the Trustee, upon written request from the Issuers, will authenticate and mail
or deliver (or cause to be transferred by book entry) such new Note to such
Holder, in a principal amount equal to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by
the Issuers to the Holder thereof. The Issuers will publicly announce the
results of the Asset Sale Offer on the Purchase Date.

interest will be payable to Holders who tender Notes pursuant to the Asset Sale
Offer,

Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
this Section 3.09 or Section 4.10, the Issuers will comply with the applicable
securities laws and regulations and will not be deemed to have breached their
obligations under this Section 3.09 or Section 4.10 by virtue of such
compliance.

      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.

      The Company will pay or cause to be paid the principal of, and premium, if
any, interest and Special Interest, if any, on, the Notes on the dates and in
the manner provided in the Notes, Principal, premium, if any, interest and

or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,

Rights Agreement, the Company will file a copy of each of the reports referred

time periods specified in the rules and regulations applicable to such reports
(unless the SEC will not accept such a filing or the Company has elected to pay
Special Interest in lieu of complying with the registration requirements of the
Registration Rights Agreement) and will post the reports on its website within
those time periods.

      If the Company is not subject to the periodic reporting requirements of
the Exchange Act for any reason, the Company will nevertheless file the reports
specified in the preceding paragraphs of this covenant with the SEC within the
time periods specified above unless the SEC will not accept such a filing or the
Company has elected to pay Special Interest in lieu of complying with the
registration requirements of the Registration Rights Agreement. However, if the

Notes remain outstanding, if at any time they are not required to file with the
SEC the reports required by the preceding paragraphs, they will furnish to the

written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination

their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 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)   So long as any of the Notes are outstanding, the Company will

or Event of Default, an Officer's Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

      The Company and each of the Guarantors covenants (to the extent that it
may lawfully do so) that it will 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 and
each of the Guarantors (to the extent that it may lawfully do so) hereby

      encumbrance or restriction will not materially adversely affect the
      Company's ability to meet its obligations on the Notes when due, and, in
      the written opinion of the president, chief operating officer or chief
      financial officer of the Company, is required in order to obtain such
      Expansion Debt and is customary for financings of such type.

            principal amount equal to the maximum potential liability of the
            Company and its Subsidiaries thereunder) not to exceed $100.0
            million, less the aggregate amount of all Net Proceeds of Asset
            Sales, Casualty Events and Condemnation Events applied by the
            Company or any of its Subsidiaries since the Closing Date to repay
            any term Indebtedness under any such Credit Facility or to repay, or
            cash collateralize letters of credit under, any revolving
            Indebtedness under any such Credit Facility and effect a
            corresponding commitment reduction thereunder;

            (2)   the incurrence by the Issuers and the Guarantors of
      Indebtedness represented by the First Priority Notes, the Notes and the
      Third Priority Notes to be issued on the Closing Date, the related

      Indentures on the Closing Date, and the Exchange Notes and the related
      Subsidiary guarantees to be issued pursuant to the Registration Rights
      Agreement;

            (3)   the incurrence by the Company or any of its Subsidiaries of
      Expansion Debt; provided, that:

                  (a)   any Expansion Debt incurred by the Excluded Subsidiary
            is recourse only to the Expansion Assets financed with such
            Expansion Debt and to other Expansion Assets owned by the Excluded
            Subsidiary (including any rights of the Excluded Subsidiary under
            Shared Facilities Arrangements);

                  (b)   if the Fixed Charge Coverage Ratio for the Company's
            most recently ended four full fiscal quarters for which internal
            financial statements are available immediately preceding the date on
            which the Expansion Debt is incurred would have been at least 2.0 to
            1.0, determined on a Pro Forma basis as if the Expansion Debt had
            been incurred at the beginning of such period and the proceeds
            therefrom had been applied as intended to be applied (but without
            giving effect to the completion of any construction projects unless
            actual completion has been achieved), at least 25% of the cost of
            such Expansion Assets is financed with Equity Contributions or the
            proceeds of Perpetual Preferred Stock or Affiliate Subordinated
            Indebtedness;

                  (c)   if the Fixed Charge Coverage Ratio for the Company's
            most recently ended four full fiscal quarters for which internal
            financial statements are available immediately preceding the date on
            which the Expansion Debt is incurred would have been less than 2.0
            to 1.0, determined on a Pro Forma basis as if the Expansion Debt had
            been incurred at the beginning of such period and the proceeds
            therefrom had been applied as intended to be applied (but without
            giving effect to the completion of any construction projects unless
            actual completion has been achieved),

                        (i)   at least 40% of the cost of such Expansion Assets
                  is financed with Equity Contributions or the proceeds of
                  Perpetual Preferred Stock or Affiliate Subordinated
                  Indebtedness, and

                        (ii)  after giving effect to such incurrence, the amount
                  of Expansion Debt incurred pursuant to this clause (3),
                  together with the aggregate amount of all other Expansion Debt
                  then outstanding, including all Permitted Refinancing
                  Indebtedness incurred to renew, refund, refinance, replace,
                  defease or discharge any Expansion Debt incurred pursuant to
                  this clause (3), does not exceed $250.0 million;

            (4)   the incurrence by the Company or any of its Subsidiaries of
      Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
      which are used to refund, refinance or replace, Indebtedness (other than
      intercompany Indebtedness) that was permitted by this Indenture to be
      incurred under clauses (2), (3), (4) or (10) of this paragraph;

            (5)   the incurrence by the Company or any Guarantor of intercompany
      Indebtedness between or among the Company and any Guarantor that is
      subordinated in right of payment to all Secured Obligations pursuant to a
      customary subordination agreement delivered to the Collateral Agent
      (together with all other documents or instruments required to effect such
      subordination and any other documents reasonably requested by the
      Collateral Agent in connection therewith), and is not secured other than
      by unperfected security interests; provided, however, that (i) any
      subsequent issuance or transfer of Equity Interests that results in any
      such Indebtedness being held by a Person other than the Company or a
      Guarantor and (ii) any sale or other transfer of any such Indebtedness to
      a Person that is not either the Company or a Guarantor will be deemed, in
      each case, to constitute an incurrence of such Indebtedness by the Company
      or such Guarantor, as the case may be, that was not permitted by this
      clause (5); and provided, further, that any such intercompany Indebtedness
      must be included in the Collateral;

            (6)   the incurrence by the Company or any of its Subsidiaries of
      Hedging Obligations, in connection with Permitted Debt or otherwise, in
      the ordinary course of business and not for speculative purposes;
      provided, that (a) such Hedging Obligations have tenors that expire on or
      prior to the maturity date (or other expiration) of the underlying
      obligation being hedged, and (b)

                                       71
<PAGE>

      any such Hedging Obligations hedging or managing interest rate risk with
      respect to (i) First Priority Lien Debt have tenors that expire on or
      prior to the Stated Maturity of the First Priority Notes, (ii) Second
      Priority Lien Debt have tenors that expire on or prior to the Stated
      Maturity of the Notes, or (iii) Third Priority Lien Debt have tenors that
      expire on or prior to the Stated Maturity of the Third Priority Notes;

            (7)   the incurrence by the Company or any of its Subsidiaries of
      Indebtedness in respect of workers' compensation claims, self-insurance
      obligations, bankers' acceptances, and performance and surety bonds in the
      ordinary course of business;

            (8)   the incurrence by the Company or any of its Subsidiaries of
      Indebtedness arising from the honoring by a bank or other financial
      institution of a check, draft or similar instrument inadvertently drawn
      against insufficient funds, so long as such Indebtedness is covered within
      five Business Days;

            (9)   the incurrence by the Company of (a) Affiliate Subordinated
      Indebtedness in an aggregate principal amount not to exceed $250.0 million
      at any one time outstanding and (b) Working Capital Facility Indebtedness
      in an aggregate principal amount not to exceed $750.0 million at any one
      time outstanding;

            (10)  the incurrence by the Company of Third Party Subordinated
      Indebtedness; provided, that:

                  (a)   the net proceeds of the Third Party Subordinated
            Indebtedness are applied:

                        (i)   to acquire all or substantially all of the assets
                  of, or any Equity Interests in, a business that constitutes a
                  Permitted Business; provided, that in the case of an
                  acquisition of Equity Interests, the business is or becomes a
                  Subsidiary of the Company and a Guarantor concurrently with
                  such acquisition;

                        (ii)  to make a capital expenditure;

                        (iii) to acquire other assets that are not classified as
                  current assets under GAAP and that are used or useful in a
                  Permitted Business; or

                        (iv)  any combination of the foregoing; and

                  (b)   the Fixed Charge Coverage Ratio for the Company's most
            recently ended four full fiscal quarters for which internal
            financial statements are available immediately preceding the date on
            which the Third Parry Subordinated Indebtedness is incurred would
            have been at least 2.0 to 1.0, determined on a Pro Forma basis as if
            the Third Party Subordinated Indebtedness had been incurred at the
            beginning of such period and the proceeds therefrom had been applied
            as intended to be applied (but without giving effect to the
            completion of any construction projects unless actual completion has
            been achieved).

      The Company will not incur, and will not permit any Subsidiary to incur,
any Indebtedness (including Permitted Debt) that is contractually subordinated
in right of payment to any other Indebtedness of the Company or such Subsidiary
unless such Indebtedness is also contractually subordinated in right of payment
to the Secured Obligations on substantially identical terms or on terms

                                       72
<PAGE>

that are more favorable to the holders of the Secured Obligations; provided,
however, that no Indebtedness will be deemed to be contractually subordinated in
right of payment to any other Indebtedness of the Company or any of its
Subsidiaries solely by virtue of being unsecured or by virtue of being secured
on a junior basis.

      For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (10) above,
the Company will be permitted to classify such item of Indebtedness on the date
of its incurrence, or later reclassify all or a portion of such item of
Indebtedness, in any manner that complies with this Section 4.09. The accrual of
interest, the accretion or amortization of original issue discount, the payment
of interest on any Indebtedness in the form of additional Indebtedness with the
same terms, and the payment of dividends on Disqualified Stock in the form of
additional shares of the same class of Disqualified Stock will not be deemed to
be an incurrence of Indebtedness or an issuance of Disqualified Stock for
purposes of this covenant. Notwithstanding any other provision of this covenant,
the maximum amount of Indebtedness that the Company or any Subsidiary may incur
pursuant to this covenant shall not be deemed to be exceeded solely as a result
of fluctuations in exchange rates or currency values.

Section 4.10 Asset Sales.

      The Company will not, and will not permit any of its Subsidiaries to,
consummate any Asset Sale unless:

            (1)   except with respect to an Asset Sale made pursuant to an
      Existing Purchase Option, the Company (or any of its Subsidiaries, as the
      case may be) receives consideration at the time of the Asset Sale at least
      equal to the Fair Market Value of the assets or Equity Interests issued or
      sold or otherwise disposed of;

            (2)   at least 90% of the consideration received in the Asset Sale
      by the Company or such Subsidiary is in the form of cash. For purposes of
      this provision, each of the following will be deemed to be cash:

                  (a)   any liabilities, as shown on the Company's most recent
            consolidated balance sheet, of the Company or any of its
            Subsidiaries (other than contingent liabilities and liabilities that
            are by their terms subordinated to the Notes or any Subsidiary
            Guarantee) that are assumed by the transferee of any such assets
            pursuant to a customary novation or similar agreement that releases
            the Company or such Subsidiary from further liability;

                  (b)   any securities, notes or other obligations received by
            the Company or any such Subsidiary from such transferee that are
            promptly, subject to ordinary settlement periods, converted by the
            Company or such Subsidiary into cash, to the extent of the cash
            received in that conversion; and

                  (c)   in connection with the exercise by a purchaser of an
            Existing Purchase Option, any amount owed by the Company or the
            applicable Subsidiary to the purchaser under the agreement
            containing such Existing Purchase Option that is set off by the
            purchaser against the purchase price;

                                       73
<PAGE>

            (3)   if the assets disposed of in such Asset Sale include any
      component of a Facility that is necessary for the operation of such
      Facility, the Asset Sale involves the disposition of such Facility as a
      whole; and

            (4)   if the Asset Sale involves the sale of a Facility or all or
      substantially all the assets of a Facility, (a) such Asset Sale is to a
      Person other than an Affiliate of the Company, and (b) all necessary
      amendments are made to those Major Project Documents applicable to such
      Facility to remove such Facility from the scope of such Major Project
      Documents.

      The Company and its Subsidiaries will be required to use the Net Proceeds
from any Asset Sale, Casualty Event or Condemnation Event to make an offer (an
"Asset Sale Offer"):

                  (1)   first, to all holders of First Priority Notes and all
            holders of other First Priority Lien Obligations (to the extent
            required under the applicable First Priority Lien Documents) to
            purchase, prepay or redeem the maximum principal amount of First
            Priority Notes and such other First Priority Lien Obligations that
            may be purchased, prepaid or redeemed out of such Net Proceeds
            (taking into account any mandatory purchase, prepayment or
            redemption of First Priority Lien Obligations required under any
            First Priority Lien Document);

                  (2)   second, if any such Net Proceeds remain after the offer
            to holders of First Priority Lien Obligations (and any mandatory
            purchase, prepayment or redemption of First Priority Lien
            Obligations) in accordance with clause (1) above, to all holders of
            Notes and all holders of other Second Priority Lien Obligations (to
            the extent required under the applicable Second Priority Lien
            Documents) to purchase, prepay or redeem the maximum principal
            amount of Notes and such other Second Priority Lien Obligations that
            may be purchased, prepaid or redeemed out of such remaining Net
            Proceeds (taking into account any mandatory purchase, prepayment or
            redemption of Second Priority Lien Obligations required under any
            Second Priority Lien Document); and

                  (3)   third, if any such Net Proceeds remain after the offer
            to holders of First Priority Lien Obligations and Second Priority
            Lien Obligations (and any mandatory purchase, prepayment or
            redemption of First Priority Lien Obligations and Second Priority
            Lien Obligations) in accordance with clauses (1) and (2) above, to
            all holders of Third Priority Notes and all holders of other Third
            Priority Lien Obligations (to the extent required under the
            applicable Third Priority Lien Documents) to purchase, prepay or
            redeem the maximum principal amount of Third Priority Notes and such
            other Third Priority Lien Obligations that may be purchased, prepaid
            or redeemed out of such remaining Net Proceeds (taking into account
            any mandatory purchase, prepayment or redemption of Third Priority
            Lien Obligations required under any Third Priority Lien Document).

      The Issuers may, at their sole option, make an Asset Sale Offer in
accordance with the priorities described above with the net proceeds from any
sale, lease, conveyance or other disposition of any assets or rights not
constituting an Asset Sale. The offer price in any Asset Sale Offer will be
equal to 100% of the principal amount plus accrued and unpaid interest and
Special Interest, if any, to the date of purchase, and will be payable in cash.
If any of such Net Proceeds remain after consummation of the Asset Sale Offer,
the Company and its Subsidiaries may use those excess Net Proceeds for any
purpose not otherwise prohibited by this Indenture, including the making of
Restricted Payments in accordance with Section 4.07. If the aggregate principal
amount of Notes and other Second Priority Lien Obligations tendered into such
Asset Sale Offer or required to be purchased, prepaid or redeemed exceeds the
amount

                                       74
<PAGE>

 of Net Proceeds available therefor, the Issuers will purchase, prepay or redeem
 Notes and such other Second Priority Lien Obligations on a pro rota basis based
 on the principal amount of Notes and such other Second Priority Lien
 Obligations tendered (or required to be purchased, prepaid or redeemed), with
 such adjustments as may be deemed appropriate by the Company so that only Notes
 in denominations of $1,000, or integral multiples thereof, will be purchased,
 prepaid or redeemed. The Issuers will comply with the procedures set forth in
 Section 3.09 with respect to any Asset Sale Offer.

Section 4.11 Transactions with Affiliates.

      The Company will not, and will not permit any of its Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate of the Company
(each, an "Affiliate Transaction"), unless:

            (1)   the Affiliate Transaction, taken as a whole with all other
      related Affiliate Transactions, is on terms that are no less favorable to
      the Company and its Subsidiaries, taken as a whole, than those that would
      have been obtained in a comparable transaction by the Company or such
      Subsidiary with an unrelated Person; and

            (2)   the Company delivers to the Trustee (other than with respect
      to a Shared Facilities Arrangement between or among the Company and/or any
      of its Subsidiaries):

                  (a)   with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $10.0 million but less than or equal to $25.0 million, a
            resolution of the Board of Directors set forth in an Officer's
            Certificate certifying that such Affiliate Transaction complies with
            this covenant and that such Affiliate Transaction has been approved
            by a majority 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 $25.0 million, a positive opinion as to the Fair Market
            Value of such Affiliate Transaction issued by an accounting,
            appraisal or investment banking firm of national standing.

      The following items will not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

            (1)   any employment agreement, employee benefit plan, officer and
      director indemnification agreement or any similar arrangement entered into
      by the Company or any of its Subsidiaries in the ordinary course of
      business;

            (2)   transactions between or among the Company and/or any of the
      Guarantors (other than Shared Facility Arrangements);

            (3)   transactions with a Person that is an Affiliate of the Company
      (but not a Subsidiary of the Company) solely because the Company owns,
      directly or through a Subsidiary, an Equity Interest in, or controls, such
      Person;

            (4)   payment of reasonable directors' fees to Persons who are not
      otherwise Affiliates of the Company;

                                       75
<PAGE>

            (5)   any issuance of Equity Interests (other than Disqualified
      Stock) of the Company to Affiliates of the Company; provided, that such
      Equity Interests are included in the Collateral;

            (6)   Restricted Payments that do not violate Section 4.07;

            (7)   loans or advances to employees in the ordinary course of
      business not to exceed $1.0 million in the aggregate at any one time
      outstanding;

            (8)   Permitted Tax Payments;

            (9)   transactions under or pursuant to written agreements with
      Affiliates of the Company in place as of the Closing Date or any amendment
      or modification thereto, so long as any such amendment or modification
      meets the requirements of clause (10) or (11) of this paragraph;

            (10)  any amendments or modifications of, or waivers under, any
      written agreement described under clause (9) of this paragraph that is not
      a Major Project Document; provided, that no such amendment, modification
      or waiver alters any such agreement in a manner that is materially adverse
      to the Holders;

            (11)  any amendments or modifications of, or waivers under, any
      Major Project Document, which are permitted by Section 4.13 and are on
      terms that are no less favorable to the Company or its relevant Subsidiary
      (as certified to the Trustee in an Officer's Certificate) than those that
      would have been obtained in a comparable transaction by the Company or
      such Subsidiary with an unrelated Person; and

            (12)  any agreement to do any of the foregoing.

Section 4.12 Liens.

        The Company will not, and will not permit any of its Subsidiaries to,
 directly or indirectly, create, incur, assume or suffer to exist any Lien of
 any kind on any asset now owned or hereafter acquired, except Permitted Liens.

Section 4.13 Business Activities.

      The Company will not, and will not permit any of its Subsidiaries to,
engage in any business other than Permitted Businesses, except to such extent as
would not be material to the Company and its Subsidiaries taken as a whole.

        The Company will, and will cause its Subsidiaries to, perform all their
obligations under the Major Project Documents, and the Company will not, and
will not permit any of its Subsidiaries to, terminate, amend or otherwise
modify, or consent to any termination, amendment or modification of, or grant
any waiver under, any Major Project Document, unless any failure to so perform
or any such termination, amendment, modification or waiver would not, when taken
together with all other such failures to perform, terminations, amendments,
modifications and waivers since the Closing Date, be Materially Adverse, as
evidenced by a certificate of the chief financial officer of the Company;
provided, however, that the provisions of this paragraph will not apply to any
amendment, modification or termination of any Major Project Document required
under this Indenture in connection with an Asset Sale.

                                       76
<PAGE>

      The Company will, and will cause its Subsidiaries to, obtain and maintain
all permits and approvals necessary for the construction and operation of the
Facilities, including applicable exemptions from PUHCA, unless the failure to do
so would not reasonably be expected to have a Material Adverse Effect.

      The Company will not, and will not permit any of its Subsidiaries to, use
of dispose of any hazardous materials or allow any hazardous materials to be
brought onto or stored or used on or transported to or released from the
Facilities, other than in accordance with prudent industry practices and in
compliance with all applicable environmental laws, except to the extent such
non-compliance, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect.

Section 4.14 Corporate Existence.

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

            (1)   its corporate existence, and the corporate, partnership or
      other existence of each of its Subsidiaries, in accordance with the
      respective organizational documents (as the same may be amended from time
      to time) of the Company or any such Subsidiary; and

            (2)   the rights (charter and statutory), licenses and franchises of
      the Company and its Subsidiaries; provided, however, that the Company will
      not be required to preserve any such right, license or franchise, or the
      corporate, partnership or other existence of any of its 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
      Subsidiaries, taken as a whole, and that the loss thereof is not adverse
      in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

      (a)   Upon the occurrence of a Change of Control, the Issuers will make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple of $1,000) of such Holder's Notes at a
purchase price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest and Special Interest, if any, on the Notes
repurchased, to, but excluding, the date of purchase (the "Change of Control
Payment'), subject to the rights of Holders on the relevant record date to
receive interest due on the relevant interest payment date. Within 30 days
following any Change of Control, the Issuers will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and stating:

            (1)   that the Change of Control Offer is being made pursuant to
      this Section 4.15 and that all Notes tendered will be accepted for
      payment;

            (2)   the purchase price and the purchase date, which shall be no
      earlier than 30 days and no later than 60 days from the date such notice
      is mailed (the "Change of Control Payment Date");

            (3)   that any Note not tendered will continue to accrue interest;

            (4)   that, unless the Issuers default in the payment of the Change
      of Control Payment, all Notes accepted for payment pursuant to the Change
      of Control Offer will cease to accrue interest after the Change of Control
      Payment Date;

                                       77
<PAGE>

            (5)   that Holders electing to have any Notes purchased pursuant to
      a Change of Control Offer will be required to surrender the Notes, with
      the form entitled "Option of Holder to Elect Purchase" on the reverse of
      the 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 Notes delivered for purchase, and a
      statement that such Holder is withdrawing his election to have the Notes
      purchased; and

            (7)   that Holders whose Notes are being purchased only in part will
      be issued new Notes equal in principal amount to the unpurchased portion
      of the Notes surrendered, which unpurchased portion must be equal to
      $1,000 in principal amount or an integral multiple thereof.

      The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change in Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Sections 4.15, the Issuers will comply with the applicable
securities laws and regulations and will not be deemed to have breached their
obligations under this Section 4.15 by virtue of such compliance.

      (b)   On the Change of Control Payment Date, the Issuers will, to the
            extent lawful:

            (1)   accept for payment all 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 Notes or portions of Notes properly
      tendered; and

            (3)   deliver or cause to be delivered to the Trustee the Notes so
      properly accepted together with an Officer's Certificate stating the
      aggregate principal amount of Notes or portions of Notes being purchased
      by the Issuers.

      The Paying Agent will promptly mail to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee, at the
written request of the Company, will promptly authenticate and mail (or cause to
be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided,
that each new Note will be in a principal amount of $1,000 or an integral
multiple thereof.

      The Issuers will publicly announce the results of the Change of Control
Offer on or as soon as practicable after the Change of Control Payment Date.

      The provisions described above that require the Issuers to make a Change
of Control Offer following a Change in Control will be applicable whether or not
any other provisions of this Indenture are applicable. Except as described above
with respect to a Change in Control, this Indenture does not contain provisions
that permit the Holders to require that the Issuers repurchase or redeem the
Notes in event of a takeover, recapitalization or similar transaction.

                                       78
<PAGE>

      (c)   Notwithstanding anything to the contrary in this Section 4.15, the
Issuers will not be required to make a Change of Control Offer upon a Change of
Control if (1) 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 this
Section 4.15 and purchases all Notes properly tendered and not withdrawn under
the Change of Control Offer, or (2) notice of redemption has been given pursuant
to Section 3.07, unless and until there is a default in payment of the
applicable redemption price.

Section 4.16 Limitation on Issuances and Sales of Equity Interests in
Subsidiaries.

      The Company will not, and will not permit any of its Subsidiaries to,
transfer, convey, sell, lease or otherwise dispose of any Equity Interests in
any Subsidiary of the Company to any Person (other than the Company or a
Guarantor), unless:

            (1)   such transfer, conveyance, sale, lease or other disposition is
      of all the Equity Interests in such Subsidiary; and

            (2)   the Net Proceeds from such transfer, conveyance, sale, lease
      or other disposition are applied in accordance with Section 4.10.

      In addition, the Company will not permit any Subsidiary of the Company to
issue any of its Equity Interests (other than, if necessary, shares of its
Capital Stock constituting directors' qualifying shares) to any Person other
than to the Company or a Guarantor.

Section 4.17 Payments for Consent.

      The Company will not, and will not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of any Note Document unless such
consideration is offered to be paid and is paid to all Holders that consent,
waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

Section 4.18 Restrictions on Activities of CalGen Finance.

      CalGen Finance will not hold any material assets, become liable for any
material obligations or engage in any significant business activities; provided,
that CalGen Finance may be a co-obligor or guarantor with respect to
Indebtedness if the Company is an obligor on such Indebtedness and the net
proceeds of such Indebtedness are received by the Company, CalGen Finance or one
or more of the Company's other Subsidiaries.

Section 4.19 Deposit of Revenues.

      The Company will, and will cause its Subsidiaries to, deposit all revenues
received by the Company and its Subsidiaries, within 10 Business Days of receipt
thereof, in the "Revenue Account" established under the Control Agreement.
Notwithstanding the foregoing, Excess Cash Flow may be distributed in accordance
with Section 4.07.

Section 4.20 Additional Subsidiaries.

      If the Company or any of its Subsidiaries acquires or creates another
Subsidiary after the Closing Date, then (1) that newly acquired or created
Subsidiary will become a Guarantor and execute a supplemental indenture in the
form of Exhibit G and deliver an Opinion of Counsel reasonably

                                       79
<PAGE>

satisfactory to the Trustee within 30 days of the date on which it was acquired
or created, and (2) all real and personal property of that Subsidiary will
become part of the Collateral within 30 days of the date on which that
Subsidiary was acquired or created pursuant to documentation (including Security
Documents, financing statements, opinions and other documents) reasonably
satisfactory to the Trustee and the Collateral Agent.

Section 4.21 Maintenance of Insurance.

      The Company will, and will cause its Subsidiaries to, maintain with
financially sound and reputable insurance companies, insurance on their property
and assets (including the Collateral), in at least such amounts, with such
deductibles and against at least such risks as is customary for companies of the
same or similar size engaged in the same or similar businesses as those of the
Company and its Subsidiaries and furnish to the Collateral Agent, upon written
request, full information as to such Persons' property and liability insurance
carriers. The Company will, and will cause the Guarantors to, cause all their
insurance policies to name the Secured Parties, as a class, as additional
insureds, with a waiver of subrogation, and shall cause all their property and
casualty policies to name the Collateral Agent as loss payee (together with
other lien holders as their interests may appear), with 30 days notice of
cancellation or material change.

Section 4.22 Financial Covenants.

      The Company will cause the ratio of (x) Consolidated EBITDA to (y)
Consolidated Interest Expense, as of the end of each fiscal quarter of the
Company, to be equal to or greater than 1.05 to 1.0.

      The Company will cause the ratio of (x) the aggregate principal amount
outstanding of First Priority Notes, First Priority Term Loans, Revolving Loans,
Notes and Second Priority Term Loans to (y) the combined Estimated Peak Capacity
of all of the Facilities (including all Facilities in operation and under
construction) owned by the Company and its Subsidiaries (expressed in
kilowatts), as of the end of each fiscal quarter of the Company, to be equal to
or less than $235 per kilowatt.

Section 4.23 Changes in Covenants when Third Priority Notes Rated Investment
Grade.

      If on any date following the Closing Date:

            (1)   after giving effect to the suspension of covenants (and the
      Event of Default) described below in the Third Priority Indenture, the
      Third Priority Notes are rated Baa3 or better by Moody's and BBB-or
      better by S&P; and

            (2)   no Default or Event of Default shall have occurred and then be
      continuing,

then, beginning on that day and subject to the provisions of the following
paragraph, the covenants (and the Event of Default) of this Indenture
specifically listed below will be suspended:

            (a)   Section 4.07 (Restricted Payments);

            (b)   Section 4.08 (Dividend and Other Payment Restrictions
      Affecting Subsidiaries);

            (c)   Section 4.09 (Incurrence of Indebtedness and Issuance of
      Preferred Equity);

            (e)   Section 4.10 (Deposit of Revenues);

                                       80
<PAGE>

            (d)   Section 4.13 (Business Activities); and

            (f)   clause (9) under Section 6,01 (Events of Default).

      Notwithstanding the foregoing, if the rating assigned to the Third
Priority Notes by either Moody's or S&P should subsequently decline to below
Baa3 or BBB-, respectively, the foregoing covenants (and the Event of Default)
will be reinstituted with respect to the Notes as of and from the date of such
rating decline. Calculations under reinstated Section 4.07 will be made as if
such covenant had been in effect since the Closing Date except that no Default
will be deemed to have occurred solely by reason of a Restricted Payment made
while such covenant was suspended.

                                   ARTICLE 5.
                                   SUCCESSORS

Section 5.01 Merger, Consolidation, or Sale of Assets.

      The Company will not, directly or indirectly:

            (1)   consolidate or merge with or into another Person (whether or
      not the Company is the surviving corporation); or

            (2)   sell, assign, transfer, convey or otherwise dispose of all or
      substantially all of the properties or assets of the Company and its
      Subsidiaries taken as a whole, in one or more related transactions, to
      another Person; or

            (3)   lease all or substantially all of its properties or assets, in
      one or more related transactions, to any other Person.

This Section 5.01 will not apply to (A) a merger of the Company with an
Affiliate solely for the purpose of reconstituting the Company in another
jurisdiction or (B) any sale, assignment, transfer, conveyance, lease or other
disposition of assets between or among the Company and the Guarantors.

      Notwithstanding the foregoing, the Company is permitted to reorganize as a
corporation in accordance with the procedures established herein, provided, that
the Company shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that such
reorganization is not adverse to Holders (it being recognized that such
reorganization shall not be deemed adverse to the Holders solely because (i) of
the accrual of deferred tax liabilities resulting from such reorganization or
(ii) the successor or surviving corporation (a) is subject to income tax as a
corporate entity or (b) is considered to be an "includable corporation" of an
affiliated group of corporations within the meaning of the Internal Revenue Code
of 1986, as amended or any similar state or local law), and the Company delivers
to the Trustee such other certificates and other documents reasonably requested
by the Trustee in connection therewith.

Section 5.02 Successor Corporation Substituted.

      Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company and its Subsidiaries taken as a whole in a transaction that is
subject to, and that complies with the provisions of, Section 5.01, the
successor corporation formed by such consolidation 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, merger, sale, lease, conveyance
or

                                       81
<PAGE>

other disposition, the provisions of this Indenture referring to the "Company"
shall refer instead to the successor corporation and not to the Company), 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 interest on the Notes except in the case
of a sale of all of the Company's assets in a transaction that is subject to,
and that complies with the provisions of, Section 5.01.

                                   ARTICLE 6.
                             DEFAULTS AND REMEDIES

            (5)   default under any mortgage, indenture or instrument under
      which there may be issued or by which there may be secured or evidenced
      any Indebtedness for money borrowed by the Company or any of its
      Subsidiaries (or the payment of which is guaranteed by the Company or any
      of its Subsidiaries), whether such Indebtedness or guarantee existed on
      the Closing Date or is created after the Closing Date, if that default:

                  (a)   is caused by a failure to pay principal of, or interest
            or premium, if any, on such Indebtedness prior to the expiration of
            the grace period provided in such Indebtedness on the date of such
            default (a "Payment Default"); or

                  (b)   results in the acceleration of such Indebtedness prior
            to its express 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 $25.0 million or more, and such default shall not
      have been cured or waived or any such acceleration rescinded, or such
      Indebtedness repaid, within 20 days of the Company or the applicable
      Subsidiary becoming aware of such default;

            (6)   failure by the Company or any of its Subsidiaries to pay final
      judgments aggregating in excess of $25.0 million (excluding those covered
      by insurance), which judgments are not paid, discharged or stayed for a
      period of 60 days;

            (7)   the repudiation by CalGen Holdings, the Company or any of its
      Subsidiaries of any of its obligations under the Security Documents or the
      unenforceability of the Security Documents against CalGen Holdings, the

      repudiation or unenforceability relates to Collateral with a Fair Market
      Value of $25.0 million or more;

            (8)   except as permitted by this Indenture, any Subsidiary
      Guarantee shall be held in any judicial proceeding to be unenforceable or
      invalid or shall cease for any reason to be in full force and effect or
      any Guarantor, or any Person acting on behalf of any Guarantor, shall deny
      or disaffirm its obligations under its Subsidiary Guarantee, and such
      condition shall not have been cured within 30 days after written notice
      from the Trustee or the Holders of at least 25% in aggregate principal
      amount of outstanding Notes;

            (9)   breach by any Person (other than the Company or any of its
      Subsidiaries) of its obligations under, or termination or failure to be in
      full force and effect of, a Major Project Document (unless such breach,
      termination or failure to be in full force and effect would not, when
      taken together with all other such breaches, terminations or failures
      since the Closing Date (other than those that have been cured as
      contemplated below, including by entering into a replacement agreement),
      be Materially Adverse, as evidenced by an Officer's Certificate of the
      chief financial officer of the Company), unless with respect to any Major
      Project Document such breach is cured, or such Major Project Document is
      replaced with a substantially similar agreement (it being understood that
      (a) an agreement will be considered substantially similar if it would not
      be Materially Adverse and (b) the use of an Affiliate of the Company as
      the counterparty under an agreement replacing the Index Hedge will not by
      itself be considered Materially Adverse), within 60 days (or 120 days with
      respect to the Index Hedge) thereafter; and

            (10)  the Company, any of its Subsidiaries that is a Significant
      Subsidiary or any group of its Subsidiaries that taken together would
      constitute a Significant Subsidiary, pursuant to or within the meaning of
      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

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

                  (a)   is for relief against the Company, any of its
            Subsidiaries that is a Significant Subsidiary or any group of its
            Subsidiaries that taken together would constitute a Significant
            Subsidiary, in an involuntary case;

                  (b)   appoints a custodian of the Company, any of its
            Subsidiaries that is a Significant Subsidiary or any group of its
            Subsidiaries that taken together would

                                       83
<PAGE>

            constitute a Significant Subsidiary, or for all or substantially all
            of the property of the Company, any of its Subsidiaries that is a
            Significant Subsidiary or any group of its Subsidiaries that taken
            together would constitute a Significant Subsidiary; or

                  (c)   orders the liquidation of the Company, any of its
            Subsidiaries that is a Significant Subsidiary or any group of its
            Subsidiaries that taken together would constitute a Significant
            Subsidiary;

      and the order or decree remains unstayed and in effect for 60 consecutive
days;

Section 6.02 Acceleration.

      In the case of an Event of Default specified in clause (10) or (11) of
Section 6.01, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. Upon any such declaration, the Notes shall become due and
payable immediately.

      The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, 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 or Special Interest, if
any, that has become due solely because of the acceleration) have been cured or
waived.

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, premium, if any, and
interest and Special Interest, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

      The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a 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 a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of the Holders
of all of the 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 the principal of, premium and Special Interest, if any, or interest
on, the Notes (including in connection with an offer to purchase). 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.

      Subject to the provisions of the Collateral Trust Agreement, Holders of a
majority in aggregate principal amount of the then outstanding Notes may direct
the time, method and place of conducting any

                                       84
<PAGE>

 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 the rights of other Holders of Notes or
 that may involve the Trustee in personal liability.

 Section 6.06     Limitation on Suits.

      Except to enforce the right to receive payment of principal, premium, if
any, or interest or Special Interest, if any, when due, no Holder may pursue any
remedy with respect to this Indenture or the Notes unless:

            (1)   such Holder has previously given the Trustee notice that an
      Event of Default is continuing;

            (2)   Holders of at least 25% in aggregate principal amount of the
      then outstanding Notes have requested that the Trustee pursue the remedy;

            (3)   such Holders have offered the Trustee reasonable security or
      indemnity against any loss, liability or expense;

            (4)   the Trustee has not complied with such request within 60 days
      after the receipt thereof and the offer of security or indemnity; and

            (5)   Holders of a majority in aggregate principal amount of the
      Notes then outstanding have not given the Trustee a direction inconsistent
      with such request within such 60-day period.

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

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; provided,
that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution
thereof or the entry of judgment therein would, under applicable law, result in
the surrender, impairment, waiver or loss of the Lien of this Indenture upon any
property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.0.1(1) or (2) occurs and is

      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

disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the 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

disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 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 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.

      liabilities incurred, and all advances made, by the Trustee and the costs
      and expenses of collection;

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

court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.

Section 7.01 Duties of Trustee.

      (a)   If an Event of Default has occurred and is continuing, the Trustee
will 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 person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

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

      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee will examine the certificates and opinions to
      determine whether or not they conform to the requirements of this

      this Section 7.01;

      negligent in ascertaining the pertinent facts; and

            (3)   the Trustee will 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.

this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section 7.01.

      (e)   No provision of this Indenture will require the Trustee to expend or
risk its own funds or incur any liability. The Trustee will be under no

and indemnity satisfactory to it against any loss, liability or expense.

rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders have offered to the Trustee reasonable

the Company with the same rights it would have if it were not Trustee. However,

eliminate such conflict within 90 days after determining such conflicting
interest, apply to the SEC for permission to continue as trustee or resign to
the extent and in the manner provided by, and subject to the provisions of, the
TIA and this Indenture. Any Agent may do the same with like rights and duties.
The Trustee is also subject to Sections 7.10 and 7.11.

Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be
responsible for any statement or recital herein or any statement in

                                       88

      If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee will mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium or Special
Interest, if any, or interest on any 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
Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

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

      (b)   A copy of each report at the time of its mailing to the Holders of
Notes will be mailed by the Trustee to the Company and filed by the Trustee with
the SEC and each stock exchange on which the Notes are listed in accordance with
TIA Section 313(d). The Company will promptly notify the Trustee when the Notes
are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

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

      (b)   The Company and the Guarantors will indemnify the Trustee against
any and all losses, liabilities or expenses incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture and any other Note Documents to which it is a party, including the
costs and expenses of enforcing this Indenture and any other Note Documents to
which it is a party against the Company and the Guarantors (including this
Section 7.07) and defending itself against any claim (whether asserted by the
Company, the Guarantors, any Holder or any other Person) or liability, loss or
expense incurred by it in connection with the exercise or performance of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith as finally determined
by a court of competent jurisdiction. The Trustee will notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company will not relieve the Company or any of the Guarantors of
their obligations hereunder. The Company or such Guarantor will defend the claim
and the Trustee will cooperate in the defense. The Trustee may have separate
counsel and the Company will pay the reasonable fees and expenses of such
counsel. Neither the Company nor any Guarantor need pay for any settlement made
without its consent, which consent will not be unreasonably withheld.

7.07 will survive the satisfaction and discharge of this Indenture.

the Trustee will have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal of and
interest on particular Notes. Such Lien will survive the satisfaction and
discharge of this Indenture.

of Default specified in Section 6.01(10) or (11) 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.

to the extent applicable.

Section 7.08 Replacement of Trustee.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

      The Issuers may, at their option at any time, elect to have either Section
8.02 or 8.03 be applied to all outstanding Notes upon compliance with the
conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

      Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.02, the Issuers and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be deemed to have been
discharged from their obligations with respect to all outstanding Notes
(including the Subsidiary Guarantees) on the date the conditions set forth below
are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal
Defeasance means that the Issuers and the Guarantors will be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Notes
(including the Subsidiary Guarantees), which will thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 and the other Sections of
this Indenture referred to in clauses (1) and (2) below, and to have satisfied
all their other obligations under such Notes, the Subsidiary Guarantees and this
Indenture (and the Trustee, on demand of and at the expense of the Company,
shall execute proper

                                       91
<PAGE>

instruments acknowledging the same), except for the following provisions which
will survive until otherwise terminated or discharged hereunder:

            (1)   the rights of Holders of outstanding Notes to receive payments
      in respect of the principal of, or interest or premium or Special
      Interest, if any, on such Notes when such payments are due from the trust
      referred to in Section 8.04;

            (2)   the Issuers' obligations with respect to such Notes under
      Article 2 and Section 4.02;

            (3)   the rights, powers, trusts, duties and immunities of the
      Trustee hereunder and the Issuers' and the Guarantors' obligations in
      connection therewith; and

            (4)   this Article 8.

      Subject to compliance with this Article 8, the Issuers may exercise their
option under this Section 8.02 notwithstanding the prior exercise of their
option under Section 8.03.

Section 8.03 Covenant Defeasance.

      Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.03, the Issuers and the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be released from each
of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4,20, 4.21 and 4.22 with
respect to the outstanding Notes on and after the date the conditions set forth
in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the
Notes will thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but will
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes may not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes and Subsidiary Guarantees, the Issuers and the Guarantors may
omit to comply with and will 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 will not constitute a Default or an Event
of Default under Section 6.01, but, except as specified above, the remainder of
this Indenture and such Notes and Subsidiary Guarantees will be unaffected
thereby. In addition, upon the Issuers' exercise under Section 8.01 of the
option applicable to this Section 8.03, subject to the satisfaction of the
conditions set forth in Section 8.04, Sections 6.01(3) through 6.01(5) will not
constitute Events of Default.

      to pay the principal of, or interest and premium and Special Interest, if
      any, on the outstanding Notes on the Stated

            published by, the Internal Revenue Service a ruling; or

                  (B)   since the Closing Date, 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 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;

            (3)   in the case of an election under Section 8.03, the Issuers
      have delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee confirming that the Holders of the
      outstanding Notes will not recognize income, gain or loss for federal
      income tax purposes as a result of such Covenant 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 Covenant Defeasance
      had not occurred;

            (4)   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 borrowing of funds to be applied to such
      deposit);

            (5)   such Legal Defeasance or Covenant Defeasance will not result
      in a breach or violation of, or constitute a default under, any material
      agreement or instrument to which the Company or any of its Subsidiaries is
      a party or by which the Company or any of its Subsidiaries is bound;

            (6)   the Issuers must deliver to the Trustee an Officer's
      Certificate stating that the deposit was not made by the Issuers with the
      intent of preferring the Holders of Notes over the other creditors of the
      Issuers with the intent of defeating, hindering, delaying or defrauding
      creditors of the Issuers or others; and

            (7)   the Issuers must deliver to the Trustee an Officer's
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for or relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions.

      Subject to Section 8.06, all money and non-callable Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant
to Section 8.04 in respect of the outstanding Notes will be held in trust and
applied by the Trustee, in accordance with the provisions of such Notes and this
Indenture, to the

                                       93

payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of such
Notes of all sums due and to become due thereon in respect of principal, premium
and Special Interest, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

      The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 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 Notes.

      Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Issuers from time to time upon the request of the
Issuers any money or non-callable Government Securities held by them as provided
in Section 8.04 which, in the opinion of a nationally recognized investment
bank, appraisal firm or 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(1)), 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 8.0.6 Repayment to Company.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Issuers, in trust for the payment of the principal of, premium and Special
Interest, if any, or interest on any Note and remaining unclaimed for two years
after such principal, premium and Special Interest, if any, or interest has
become due and payable shall be paid to the Issuers on their request or (if then
held by the Issuers) will be discharged from such trust; and the Holder of such
Note will thereafter be permitted to look only to the Issuers for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Issuers as trustee thereof, will
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 will 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 Issuers.

Section 8.07 Reinstatement.

      If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03, 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 Issuers' and the Guarantors' obligations under this
Indenture, the Notes and the Subsidiary Guarantees will be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
until such time as the Trustee or Paying Agent is permitted to apply all such
money in accordance with Section 8.02 or 8.03, as the case may be; provided,
however, that, if the Issuers make any payment of principal of, premium or
Special Interest, if any, or interest on any Note following the reinstatement of
their obligations, the Issuers will be subrogated to the rights of the Holder of
such Note to receive such payment from the money held by the Trustee or Paying
Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

                                       94
<PAGE>

      Notwithstanding Section 9.02, the Issuers, the Guarantors and the Trustee
may, without the consent of any Holder, amend or supplement this Indenture, the
Subsidiary Guarantees or the Notes:

            (1) to cure any ambiguity, defect or inconsistency;

            (2) to provide for uncertificated Notes in addition to or in place
      of certificated Notes;

            (3) to provide for the assumption of the Issuers' obligations to the
      Holders of the Notes by a successor to the Issuers pursuant to Article 5;

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

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

            (6) to make, complete or confirm any grant of Collateral permitted
      or required by this Indenture or any of the Security Documents or any
      release of Collateral that becomes effective as set forth in this
      Indenture or any of the Security Documents;

            (7) to conform the text of this Indenture, the Subsidiary
      Guarantees, the Security Documents or the Notes to any provision of the
      "Description of Notes" section contained in the Offering Memorandum to the
      extent that such provision in such "Description of Notes" section was
      intended to be a verbatim recitation of a provision of this Indenture, the
      Subsidiary Guarantees, the Security Documents or the Notes; or

            (8) to allow any Guarantor to execute a supplemental indenture in
      the form of Exhibit G and/or a Subsidiary Guarantee with respect to the
      Notes.

      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, the Trustee will join with the Company and the Guarantors 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 will 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 Notes.

      Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.15), the Subsidiary Guarantees and the Notes with the consent
of the Holders of at least a majority in aggregate principal amount of the Notes
then outstanding voting as a single class (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for, or
purchase of, the Notes), and, subject to Sections 6.04 and 6.07, any existing
Default or Event of Default (other than a Default or Event of Default in the
payment of the principal of, premium or Special Interest, if any, or interest on
the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture, the Subsidiary
Guarantees or the Notes may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Notes voting as a
single class (including consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the

                                       95

<PAGE>

Notes). Section 2.08 shall determine which Notes are considered to be
"outstanding" for purposes of this Section 9.02.

      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 Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02, the Trustee will join
with the Company in the execution of such amended or supplemental indenture
unless such amended or supplemental indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but will not be obligated to, enter into such
amended or supplemental indenture.

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

      After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company will mail to the Holders of 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, will 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, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder):

            (1) reduce the principal amount of Notes whose Holders must consent
      to an amendment, supplement or waiver;

            (2) reduce the principal of or change the fixed maturity of any Note
      or alter the provisions with respect to the redemption of the Notes (other
      than the provisions of Sections 3.09, 4.10 and 4.15);

            (3) reduce the rate of or change the time for payment of interest,
      including default interest, on any Note;

            (4) waive a Default or Event of Default in the payment of principal
      of, or premium, interest or Special Interest, if any, on, the Notes
      (except a rescission of acceleration of the Notes by the Holders of at
      least a majority in aggregate principal amount of the then outstanding
      Notes and a waiver of the payment default that resulted from such
      acceleration);

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

            (6) make any change in the provisions of this Indenture relating to
      waivers of Defaults or Events of Default or the rights of Holders of Notes
      to receive payments of principal of, or interest, premium or Special
      Interest, if any, on the Notes;

            (7) waive a redemption payment with respect to any Note (other than
      a payment required under Section 4.10 or Section 4.15);

                                       96

<PAGE>

            (8) release any Guarantor from any of its payment obligations under
      its Subsidiary Guarantee or this Indenture, except in accordance with the
      terms of this Indenture;

            (9) release any portion of the Collateral from the Liens created by
      the Security Documents except as specifically provided for in this
      Indenture and the Security Documents; or

            (10) make any change in the preceding amendment and waiver
      provisions.

Section 9.03 Compliance with Trust Indenture Act.

      Every amendment or supplement to this Indenture or the Notes will be set
forth in an amended or supplemental indenture that complies with the TIA as then
in effect.

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

Section 9.05 Notation on or Exchange of Notes.

      The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

      Failure to make the appropriate notation or issue a new Note will not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

      The Trustee will sign any amended or supplemental indenture authorized
pursuant to this Article 9 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 the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
will be entitled to receive and (subject to Section 7.01) will be fully
protected in relying upon, in addition to the documents required by Section
13.04, 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.

Section 10.01 Equal and Ratable Sharing of Collateral by Holders of Secured Debt
Within a Class.

      Notwithstanding:

            (1) anything to the contrary contained in the Security Documents;

            (2) the time of incurrence of any Series of Secured Debt within a
      Class;

      securing any Series of Secured Debt within such Class;

            (4) the time or order of filing or recording of financing
      statements, mortgages or other documents filed or recorded to perfect any
      Lien upon any Collateral;

            (5) the time of taking possession or control over any Collateral; or

            (6) the rules for determining priority under any law governing
      relative priorities of Liens:

      (a) all Liens at any time granted by the Company or any Guarantor to
secure any of the Secured Debt within such Class will secure, equally and
ratably, all present and future Secured Obligations within such Class; and

      (b) all proceeds of all Liens at any time granted by the Company or any
Guarantor to secure any of the Secured Debt and other Secured Obligations within
such Class will be allocated and distributed equally and ratably on account of
the Secured Debt and other Secured Obligations within such Class; provided, that
in the absence of an Event of Default, subject to the requirements set forth in
Sections 3.09 and 4.10, the Company and the Guarantors shall be entitled to
utilize cash proceeds of Collateral in the ordinary course of their business.

      The foregoing provision is intended for the benefit of, and will be
enforceable as a third party beneficiary by, each present and future holder of
Secured Obligations within the applicable Class, each present and future Secured
Debt Representative therefor and the Collateral Agent as holder of Secured
Obligations within such Class. The Secured Debt Representative of each future
Series of Secured Debt within a Class will be required to deliver a Sharing
Confirmation to the Collateral Agent and the Trustee at the time of incurrence
of such Series of Secured Debt.

Section 10.02 Class Voting.

      With respect to any vote to be cast by the Trustee on behalf of the
Holders in accordance with Article 4 of the Collateral Trust Agreement, the
Trustee will vote all of such Notes as directed by the Holders of a majority in
aggregate principal amount of the outstanding principal amount of Notes. For
purposes of such direction to the Trustee, Notes registered in the name of, or
Beneficially Owned by, the Company or an Affiliate of the Company will be deemed
not to be outstanding.

      Notwithstanding:

            (1) anything to the contrary contained in the Security Documents;

            (2) the time of incurrence of any Series of Secured Debt;

      statements, mortgages or other documents filed or recorded to perfect any
      Lien upon any Collateral;

            (6) the rules for determining priority under any law governing
      relative priorities of Liens,

all Liens at any time granted by the Company or any Guarantor to secure any of
the Second Priority Lien Obligations will be subject and subordinate to all
First Priority Liens securing First Priority Lien Debt up to the First Priority
Lien Cap and all related First Priority Lien Obligations.

enforceable as a third party beneficiary by, each present and future holder of

Second Priority Lien Debt will be required to deliver a Lien Priority
Confirmation to the Collateral Agent and each First Priority Debt Representative
at the time of incurrence of such Series of Second Priority Lien Debt.

      In addition, the foregoing provision is intended solely to set forth the
relative ranking, as Liens, of the Liens securing Second Priority Lien Debt as
against the First Priority Liens. Neither the Notes nor any other Second
Priority Lien Obligations nor the exercise or enforcement of any right or remedy
for the payment or collection thereof are intended to be, or will ever be by
reason of the foregoing provision, in any respect subordinated, deferred,
postponed, restricted or prejudiced.

Section 10.04 Relative Rights.

      Nothing in the Note Documents will:

            (1) impair, as between the Company and the holders of the Notes, the
      obligation of the Company to pay principal of, premium and interest, if
      any, on the Notes in accordance with their terms or any other obligation
      of the Company or any other obligor under the Note Documents;

            (2) affect the relative rights of holders of Notes as against any
      other creditors of the Company or any Guarantor (other than holders of
      other Secured Obligations);

            (3) restrict the right of any holder of Notes to sue for payments
      that are then due and owing (but not enforce any judgment in respect
      thereof against any Collateral to the extent specifically prohibited by
      the provisions of the Collateral Trust Agreement);

            (4) restrict or prevent any holder of Notes, the Trustee, the

the Notes or any other Note Obligations, and the right of the holders of the
Notes and such Note Obligations to the benefits and proceeds of the Collateral

above, the Trustee will authorize the Collateral Agent to release the Liens on
the Collateral securing the Notes.

                              SUBSIDIARY GUARANTEES

Section 11.01 Guarantee.

      (a) Subject to this Article 11 and the limitations set forth in Section
13.07, each of the Guarantors hereby, jointly and severally, unconditionally
guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, irrespective of the validity
and enforceability of this Indenture, the Notes or the obligations of the
Company hereunder or thereunder, that:

            (1) the principal of, premium and Special Interest, if any, and
      interest on the Notes will be promptly paid in full when due, whether at
      maturity, by acceleration, redemption or otherwise, and interest on the
      overdue principal of and interest and Special Interest, if any, on the
      Notes, if any, if lawful, and all other obligations of the Company to the
      Holders or the Trustee hereunder or thereunder will be promptly paid in
      full or performed, all in accordance with the terms hereof and thereof;
      and

            (2) in case of any extension of time of payment or renewal of any
      Notes or any of such other obligations, that same will be promptly paid in
      full when due or performed in accordance with the terms of the extension
      or renewal, whether at stated maturity, by acceleration or otherwise.

      Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

      (b) Subject to the limitations set forth in Section 13.07, the Guarantors
hereby agree that their obligations hereunder are unconditional, irrespective of
the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
of the Notes with respect to any provisions hereof or thereof, the recovery of
any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. Each Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands

                                      100

<PAGE>

whatsoever and covenant that this Subsidiary Guarantee will not be discharged
except by complete performance of the obligations contained in the Notes and
this Indenture.

      (c) If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company or the
Guarantors, any amount paid by either to the Trustee or such Holder, this
Subsidiary Guarantee, to the extent theretofore discharged, will be reinstated
in full force and effect.

      (d) Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 for
the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6, such obligations (whether or not due
and payable) will forthwith become due and payable by the Guarantors for the
purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 11.02 Limitation on Guarantor Liability.

      Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Subsidiary
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance
for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree
that the obligations of such Guarantor will be limited to the maximum amount
that will, after giving effect to such maximum amount and all other contingent
and fixed liabilities of such Guarantor that are relevant under such laws, and
after giving effect to any collections from, rights to receive contribution from
or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under this Article 11, result in the
obligations of such Guarantor under its Subsidiary Guarantee not constituting a
fraudulent transfer or conveyance.

Section 11.03 Execution and Delivery of Subsidiary Guarantee.

      To evidence its Subsidiary Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Subsidiary Guarantee
substantially in the form attached as Exhibit F will be endorsed by an Officer
of such Guarantor on each Note authenticated and delivered by the Trustee and
that this Indenture will be executed on behalf of such Guarantor by one of its
Officers.

      Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in
Section 11.01 will remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Subsidiary Guarantee.

      If an Officer whose signature is on this Indenture or on the Subsidiary
Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will
be valid nevertheless.

      The delivery of any Note by the Trustee, after the authentication thereof
hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in
this Indenture on behalf of the Guarantors.

                                       101

<PAGE>

      In the event that the Company creates or acquires any Subsidiary after the
Closing Date, if required by Section 4.21, the Company will cause such
Subsidiary to comply with the provisions of Section 4.21 and this Article 11, to
the extent applicable.

Section 11.04 Guarantors May Consolidate, etc., on Certain Terms.

      Except as otherwise provided in Section 11.05, no Guarantor may sell or
otherwise dispose of all or substantially all of its assets to, or consolidate
with or merge with or into (whether or not such Guarantor is the surviving
Person), another Person, other than the Company or another Guarantor, except as
permitted by Section 4.10.

      In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture in the form of
Exhibit G, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and
punctual performance of all of the covenants and conditions of this Indenture to
be performed by the Guarantor, such successor Person will succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed
any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee. All the Subsidiary Guarantees so issued will in
all respects have the same legal rank and benefit under this Indenture as the
Subsidiary Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all of such Subsidiary Guarantees had been
issued at the date of the execution hereof.

      Except as set forth in Articles 4 and 5, nothing contained in this
Indenture or in any of the Notes will prevent any consolidation or merger of a
Guarantor with or into the Company or another Guarantor, or will prevent any
sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety to the Company or another Guarantor.

Section 11.05 Releases Following Sale of Assets.

      In the event of any sale or other disposition of all or substantially all
of the assets of any Guarantor, by way of merger, consolidation or otherwise, or
a sale or other disposition of all of the Capital Stock of any Guarantor, in
each case to a Person that is not (either before or after giving effect to such
transactions) the Company or a Guarantor, then such Guarantor (in the event of a
sale or other disposition, by way of merger, consolidation or otherwise, of all
of the Capital Stock of such Guarantor) or the Person acquiring the property (in
the event of a sale or other disposition of all or substantially all of the
assets of such Guarantor) will be released and relieved of any obligations under
its Subsidiary Guarantee; provided, that the Net Proceeds of such sale or other
disposition are applied in accordance with the applicable provisions of this
Indenture, including without limitation Section 4.10, Upon delivery by the
Company to the Trustee of an Officer's Certificate and an Opinion of Counsel to
the effect that such sale or other disposition was made by the Company in
accordance with the provisions of this Indenture, including without limitation
Section 4.10, the Trustee will execute any documents reasonably required in
order to evidence the release of any Guarantor from its obligations under its
Subsidiary Guarantee.

      Any Guarantor not released from its obligations under its Subsidiary
Guarantee will remain liable for the full amount of principal of and interest
and premium and Special Interest, if any, on the Notes and for the other
obligations of any Guarantor under this Indenture as provided in this Article
11.

                           SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

      This Indenture will be discharged and will cease to be of further effect
as to all Notes issued hereunder, when:

            (1) either:

                  (a) all Notes that have been authenticated (except lost,
      stolen or destroyed Notes that have been replaced or paid and Notes for
      whose payment money has theretofore been deposited in trust and thereafter
      repaid to the Issuers) have been delivered to the Trustee for
      cancellation; or

                  (b) all Notes that have not been delivered to the Trustee for
      cancellation have become due and payable by reason of the mailing of a
      notice of redemption or otherwise or will become due and payable within
      one year and the Issuers have or any Guarantor has irrevocably deposited
      or caused to be deposited with the Trustee as trust funds in trust solely
      for the benefit of the Holders, cash in U.S. dollars, non-callable
      Government Securities, or a combination thereof, in such amounts as will
      be sufficient without consideration of any reinvestment of interest, to
      pay and discharge the entire indebtedness on the Notes not delivered to
      the Trustee for cancellation for principal, premium and Special Interest,
      if any, and accrued interest to the date of maturity or redemption;

            (2) no Default or Event of Default has occurred and is continuing on
      the date of such deposit or will occur as a result of such deposit and
      such deposit will not result in a breach or violation of, or constitute a
      default under, any other instrument to which the Issuers are or any
      Guarantor is a party or by which the Issuers are or any Guarantor is
      bound;

            (3) the Issuers have or any Guarantor has paid or caused to be paid
      all sums payable by it under this Indenture; and

            (4) the Issuers have delivered irrevocable instructions to the
      Trustee under this Indenture to apply the deposited money toward the
      payment of the Notes at maturity or the redemption date, as the case may
      be.

In addition, the Issuers must deliver an Officer's Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

      Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section 12.01, the provisions of Section 12.02 and Section 8.06 will
survive. In addition, nothing in this Section 12.01 will be deemed to discharge
those provisions of Section 7.07, that, by their terms, survive the satisfaction
and discharge of this Indenture.

Section 12.02 Application of Trust Money.

      Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in
accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including either Issuer acting

                                       103

<PAGE>

as Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium and Special Interest, if any) and interest for
whose payment such money has been deposited with the Trustee; but such money
need not be segregated from other funds except to the extent required by law.

      If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with Section 12.01 by reason of any legal proceeding or
by reason of any order or judgment of any court or Governmental Authority
enjoining, restraining or otherwise prohibiting such application, the Company's
and any Guarantor's obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section
12.01; provided, that if the Issuers have made any payment of principal of,
premium or Special Interest, if any, or interest on any Notes because of the
reinstatement of its obligations, the Issuers shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or
Government Securities held by the Trustee or Paying Agent.

      If the Company mails a notice or communication to Holders, it will mail a

Section 13.03 Communication by Holders of Notes with Other Holders of Notes.

      Holders may communicate pursuant to TIA Section 312(b) with other Holders
with respect to their rights under this Indenture or the Notes. The Company, the

312(c).

Section 13.04 Certificate and Opinion as to Conditions Precedent.

      Upon any request or application by the Company to the Trustee to take any
action under this Indenture, the Company shall furnish to the Trustee:

            (1) an Officer's Certificate in form and substance reasonably
      satisfactory to the Trustee (which must include the statements set forth
      in Section 13.05) stating that, in the opinion of the signers, all
      conditions precedent and covenants, if any, provided for in this Indenture

Section 314(e) and must include:

            (1) a statement that the Person making such certificate or opinion

Employees and Stockholders.

      Notwithstanding anything to the contrary set forth in this Indenture, the
Notes, any Security Document or any other Note Document, the Notes and the
Subsidiary Guarantees are non-recourse secured obligations of the Company and
Guarantors, respectively. The only recourse a Holder will have with respect to
the payment of principal of, or interest, or premium on, the Notes (whether
under the Indenture or the Notes, or pursuant to the Subsidiary Guarantees) will
be enforcement of its rights against CalGen Finance under this Indenture or
against the Collateral pursuant to the Security Documents. The Holders will have
no recourse to the equity or assets of the Excluded Subsidiary.

      No director, officer, employee, incorporator, stockholder, or partner of
the Company or any of its Subsidiaries, as such, will have any liability for any
obligations of the Issuers or any of its Subsidiaries under the Notes, this
Indenture, the Subsidiary Guarantees or the Security Documents, or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Notes by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.
The waiver may not be effective to waive liabilities under the federal
securities laws.

      THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO
CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES

THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED

      provisions of the Indenture, the provisions of the Indenture shall govern
      and be controlling. The Notes are secured obligations of the Company and
      CalGen Finance limited to $640.0 million in aggregate principal amount.

      percentages of principal amount) set forth below plus accrued and unpaid
      interest and Special Interest, if any, on the Notes redeemed, to the
      applicable redemption date, if redeemed during the twelve-month period
      beginning on April 1 of the years indicated below, subject to the rights
      of the Holders on the relevant record date to receive interest on the
      relevant interest payment date:

<TABLE>

      will make an offer (a "Change of Control Offer") to each Holder to
      repurchase all or any part (equal to $1,000 or an integral multiple of
      $1,000) of such Holder's Notes at a purchase price in cash equal to 101%
      of the aggregate principal amount thereof plus accrued and unpaid interest

      any Asset Sale, Casualty Event or Condemnation Event remaining after all
      required purchases, prepayments and and/or redemptions of First Priority
      Lien Obligations to offer to prepay Notes and other Second Priority Lien
      Obligations (an "Asset Sale Offer"). The offer price in any Asset Sale
      Offer will be equal to 100% of the principal amount plus accrued and
      unpaid interest and Special Interest, if any, on the Notes purchased, to,
      but excluding, the date of purchase, and will be payable in cash, subject

      due on the relevant interest payment date. If the aggregate principal
      amount of Notes and other Second Priority Lien Obligations tendered into
      such Asset Sale Offer (or required to be purchased, prepaid or redeemed)
      exceeds the amount of Net Proceeds available therefor, the Trustee will
      select the Notes and such other Second Priority Lien Obligations to be
      purchased on a pro rata basis.

            (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address. Notes in
      denominations larger than $1,000 may be redeemed in part but only in whole
      multiples of $1,000, unless all of the Notes held by a Holder are to be
      redeemed. On and after the redemption date interest ceases to accrue on
      Notes or portions thereof called for redemption.

            (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
      form without coupons in denominations of $1,000 and integral multiples
      thereof. The transfer of Notes may be registered and Notes may be

      require a Holder, among other things, to furnish appropriate endorsements
      and transfer documents and the Company may require a Holder to pay any
      taxes and fees required by law or permitted by the Indenture. The Company
      need not exchange or register the transfer of any Note or portion of a
      Note selected for redemption, except for the unredeemed portion of any
      Note being redeemed in part. Also, the Company need not exchange or
      register the transfer of any Notes for a period of 15 days before a
      selection of Notes to be redeemed or during the period between a record
      date and the corresponding Interest Payment Date.

            (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
      treated as its owner for all purposes.

            (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions
      and the Collateral Trust Agreement, the Indenture, the Subsidiary
      Guarantees and the Notes may be amended or supplemented with the consent
      of the Holders of at least a majority in aggregate principal amount of the

      requirements of the SEC in order to effect or maintain the qualification
      of the Indenture under the Trust Indenture

      under such Guarantor's Subsidiary Guarantee; (ix) the breach by any Person
      (other than the Company and its Subsidiaries) of its obligations under, or
      the termination or Failure to be in full force of, a Major Project
      Document, unless such breach when taken together with all other such
      breaches would not be materially adverse to the Company and its
      Subsidiaries taken as a whole; and (x) certain events of bankruptcy or
      insolvency with respect to the Company or any of its Significant
      Subsidiaries. If any Event of Default occurs and is continuing, the
      Trustee or the Holders of at least 25% in aggregate principal amount of
      the then outstanding Notes may declare all the Notes to be due and
      payable. Notwithstanding the foregoing, in the case of an Event of Default
      arising from certain events of bankruptcy or insolvency, all outstanding
      Notes will become due and payable without further action or notice.
      Holders may not enforce the Indenture or the Notes except as provided in
      the Indenture and the Collateral Trust Agreement. Subject to certain
      limitations, Holders of a majority in principal amount of the then
      outstanding Notes may direct the Trustee in its exercise of any trust or
      power. The Trustee may withhold from Holders of the Notes notice of any
      continuing Default or Event of Default (except a Default or Event of
      Default relating to the payment of principal, interest or premium or
      Special Interest, if any) if it determines that withholding notice is in
      their interest The Holders of a majority in aggregate principal amount of
      the Notes then outstanding by notice to the Trustee may on behalf of the
      Holders of all of the Notes waive any existing Default or Event of Default
      and its consequences under the Indenture except a continuing Default or
      Event of Default in the payment of principal of, or premium, if any, or
      interest or Special Interest, if any, on, the Notes. The Issuers are
      required to deliver to the Trustee annually a statement regarding
      compliance with the Indenture, and the Issuers are required upon becoming
      aware of any Default or Event of Default, to deliver to the Trustee a
      statement specifying such Default or Event of Default.

            (13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
      or any other capacity, may make loans to, accept deposits from, and
      perform services for the Company or its Affiliates, and may otherwise deal
      with the Company or its Affiliates, as if it were not the Trustee.

            (14) No RECOURSE AGAINST OTHERS. A director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      not have any liability for any obligations of the Company or such
      Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or
      for any claim based on, in respect of, or by reason of, such obligations
      or their creation. Each Holder by accepting a Note waives and releases all
      such liability. This waiver and release are part of the consideration for
      the issuance of the Notes.

            (15) AUTHENTICATION. This Note will not be valid until authenticated
      by the manual signature of the Trustee or an authenticating agent.

            (16) ABBREVIATIONS. Customary abbreviations may be used in the name
      of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN
      ENT (= tenants by the entireties), JT TEN (= joint tenants with right of

            (17) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
      RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders

      "Registration Rights Agreement"), among the Company, CalGen Finance, the
      Guarantors and the initial purchaser of the Notes.

            (18) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
      Committee on Uniform Security Identification Procedures, the Company has
      caused CUSIP numbers to be printed on the Notes and the Trustee may use
      CUSIP numbers in notices of redemption as a convenience to Holders. No
      representation is made as to the accuracy of such numbers either as
      printed on the Notes or as contained in any notice of redemption and
      reliance may be placed only on the other identification numbers placed
      thereon.

      a holder of the Notes will have with respect to the payment of principal
      of, or interest or premium or Special Interest, if any, on, this Note
      (whether under the Indenture or the Note, or pursuant to the Subsidiary
      Guarantees) will be enforcement of its rights against CalGen Finance under
      the Indenture or against the Collateral pursuant to the Security
      Documents.

charge a copy of the Indenture, the Registration Rights Agreement and the
Security Documents. Requests may be made to:

      Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

            (1) INTEREST. Calpine Generating Company, LLC, a Delaware limited
      liability company (the "Company"), and CalGen Finance Corp., a Delaware
      corporation ("CalGen Finance" and, together with the Company, the
      "Issuers"), jointly and severally promise to pay interest on the principal
      amount of this Note at the Applicable Second Priority LIBOR Rate (as
      defined below) per annum from March 23, 2004 until maturity and will pay
      the Special Interest, if any, payable pursuant to the Registration Rights
      Agreement referred to below. The Issuers will pay interest and Special
      Interest, if any, semiannually in arrears on January 1, April 1, July 1
      and October 1 of each year or, if any such day is not a Business Day, on
      the next succeeding Business Day (each, an "Interest Payment Date").
      Interest on the Notes will accrue from the most recent date to which
      interest has been paid or, if no interest has been paid, from the date of
      issuance; provided, that if there is no existing Default in the payment of
      interest, and if this Note is authenticated between a record date referred
      to on the face hereof and the next succeeding Interest Payment Date,
      interest shall accrue from such next succeeding Interest Payment Date;
      provided, further, that the first Interest Payment Date will be July 1,
      2004. The Issuers will pay interest (including post-petition interest in
      any proceeding under any Bankruptcy Law) on overdue principal and premium,
      if any, from time to time on demand at a rate that is 1% per annum in
      excess of the rate then in effect. The Issuers will pay interest
      (including post-petition interest in any proceeding under any Bankruptcy
      Law) on overdue installments of interest and Special Interest (without
      regard to any applicable grace periods) from time to time on demand at

                                   EXHIBIT B-4

<PAGE>

      the same rate to the extent lawful. Interest will be computed on the basis
      of a 360-day year of twelve 30-day months.

            "Applicable Second Priority LIBOR Rate" means, for each interest
      period, 575 basis points over the rate determined by the Company (notice
      of such rate to be sent to the Trustee by the Company on the date of
      determination thereof) equal to the greater of (x) 1.250% or (y) the
      applicable British Bankers' Association LIBOR rate for deposits in U.S.
      dollars for a period of one, two, three or six months (as the Company may
      elect in an Officer's Certificate delivered to the Trustee as reported by
      any generally recognized financial information service as of 11:00 a.m.
      (London time) two Business Days prior to the first day of such interest
      period; provided, that, if no such British Bankers' Association LIBOR rate
      is available to the Company, the Applicable Second Priority LIBOR Rate for
      the relevant interest period shall instead be the rate at which Morgan
      Stanley Senior Funding, Inc. or one of its affiliate banks offers to place
      deposits in U.S. dollars with first-class banks in the London interbank
      market for a period of one, two, three or six months (as applicable) as of
      approximately 11:00 a.m. (London time) two Business Days prior to the
      first day of such interest period, in amounts equal to $1.0 million.

            PRINCIPAL. The Issuers jointly and severally promise to pay
      principal of the Notes in quarterly installments, commencing July 1, 2008,
      as follows:

      Notes will be payable as to principal, premium, interest and Special

      such purpose within or without the City and State of New York, or, at the
      option of the Company, payment of interest and Special Interest, if any,

      an office or agency where Notes may be presented for payment ("Paying
      Agent"). The Registrar will keep a register of the Notes and of their
      transfer and exchange. The Issuers 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 Issuers may change any Paying Agent or Registrar without
      notice to any Holder. The Company will notify the Trustee in writing of
      the name and address of any Agent not a party to the Indenture. If the
      Issuers fail to appoint or maintain another entity as Registrar or Paying
      Agent, the Trustee shall act as such. The Company or any of its
      Subsidiaries may act as Paying Agent or Registrar. The Issuers initially
      appoint The Depository Trust Company to act as Depositary with respect to
      the Global Notes. The Issuers initially appoint the Trustee to act as the
      Registrar and Paying Agent and to act as Custodian with respect to the
      Global Notes.

            (4) INDENTURE. The Company issued the Notes under a Second Priority
      Indenture, dated as of March 23, 2004 (the "Indenture"), among the
      Issuers, the Guarantors and the Trustee. The terms of the Notes include
      those stated in the Indenture and those made part of the Indenture by
      reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code
      Sections 77aaa-77bbbb). The Notes are subject to all such terms, and
      Holders are referred to the Indenture and such Act for a statement of such
      terms. To the extent any provision of this Note conflicts with the express
      provisions of the Indenture, the provisions of the Indenture shall govern
      and be controlling. The Notes are secured obligations of the Company and
      CalGen Finance limited to $640.0 million in aggregate principal amount.
      The Notes are secured on a second-priority basis, Equally and Ratably with
      all other Second Priority Lien Obligations, by (a) a security interest in
      all the assets of the Company and the Guarantors other than Excluded
      Assets, and (b) a pledge of the equity interests in the Company and CalGen
      Expansion Company, LLC, subject to liens securing First Priority Lien
      Obligations and other Permitted Prior Liens.

            (5) OPTIONAL REDEMPTION. The Issuers may not redeem all or any part
      of the Notes prior to April 1, 2008. On or after April 1, 2008, the
      Issuers may redeem all or a part of the Notes, upon not less than 30 nor
      more than 60 days prior notice, at the redemption prices (expressed at
      percentages of principal amount) set forth below plus accrued and unpaid
      interest and Special Interest, if any, on the Notes redeemed, to the
      applicable redemption date, if redeemed during the twelve-month period
      beginning on April 1 of the years indicated below, subject to the rights
      of the Holders on the relevant record date to receive interest on the
      relevant interest payment date:

            Unless the Company defaults in the payment of the redemption price,
      interest will cease to accrue on the Notes or portions thereof called for
      redemption on the applicable redemption date.

<PAGE>

            (6) MANDATORY REDEMPTION. The Issuers will not be required to make
      mandatory redemption or sinking fund payments with respect to the Notes.

            (7) REPURCHASE AT OPTION OF HOLDER.

                  (a) Upon the occurrence of a Change of Control, the Issuers
      will make an offer (a "Change of Control Offer") to each Holder to
      repurchase all or any part (equal to $1,000 or an integral multiple of
      $1,000) of such Holder's Notes at a purchase price in cash equal to 101%
      of the aggregate principal amount thereof plus accrued and unpaid interest
      and Special Interest, if any, on the Notes purchased, to, but excluding,
      the date of purchase, subject to the rights of Holders on the relevant
      record date to receive interest due on the relevant interest payment date.
      Within 30 days following any Change of Control, the Issuers will mail a
      notice to each Holder describing the transaction or transactions that
      constitute the Change of Control and stating the procedures governing the
      Change of Control Offer as required by Section 4.15 of the Indenture.

                  (b) The Issuers will be required to use the Net Proceeds from
      any Asset Sale, Casualty Event or Condemnation Event remaining after all
      required purchases, prepayments and and/or redemptions of First Priority
      Lien Obligations to offer to prepay Notes and other Second Priority Lien
      Obligations (an "Asset Sale Offer"). The offer price in any Asset Sale
      Offer will be equal to 100% of the principal amount plus accrued and
      unpaid interest and Special Interest, if any, on the Notes purchased, to,
      but excluding, the date of purchase, and will be payable in cash, subject
      to the rights of Holders on the relevant record date to receive interest
      due on the relevant interest payment date. If the aggregate principal
      amount of Notes and other Second Priority Lien Obligations tendered into
      such Asset Sale Offer (or required to be purchased, prepaid or redeemed)
      exceeds the amount of Net Proceeds available therefor, the Trustee will
      select the Notes and such other Second Priority Lien Obligations to be
      purchased on a pro rata basis.

            (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address. Notes in
      denominations larger than $1,000 may be redeemed in part but only in whole
      multiples of $1,000, unless all of the Notes held by a Holder are to be
      redeemed. On and after the redemption date interest ceases to accrue on
      Notes or portions thereof called for redemption.

            (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
      form without coupons in denominations of $1,000 and integral multiples
      thereof. The transfer of Notes may be registered and Notes may be
      exchanged as provided in the Indenture. The Registrar and the Trustee may
      require a Holder, among other things, to furnish appropriate endorsements
      and transfer documents and the Company may require a Holder to pay any
      taxes and fees required by law or permitted by the Indenture. The Company
      need not exchange or register the transfer of any Note or portion of a
      Note selected for redemption, except for the unredeemed portion of any
      Note being redeemed in part. Also, the Company need not exchange or
      register the transfer of any Notes for a period of 15 days before a
      selection of Notes to be redeemed or during the period between a record
      date and the corresponding Interest Payment Date.

part for one or more Global Notes only (i) on or after the termination of the
40-day restricted period (as defined in Regulation S) and (ii) upon presentation

            (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
      treated as its owner for all purposes.

            (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions
      and the Collateral Trust Agreement, the Indenture, the Subsidiary
      Guarantees and the Notes may be amended or supplemented with the consent
      of the Holders of at least a majority in aggregate principal amount of the
      Notes then outstanding (including consents obtained in connection with a
      purchase or tender offer or exchange offer for Notes) voting as a single
      class, and any existing default or compliance with any provision of the
      Indenture, the Subsidiary Guarantees or the Notes may be waived with the
      consent of the Holders of a majority in principal amount of the Notes then
      outstanding voting as a single class. Without the consent of any Holder,
      the Indenture, the Subsidiary Guarantees and the Notes may be amended or

      for uncertificated Notes in addition to or in place of certificated Notes,

      obligations to Holders of the Notes in ease of a merger or consolidation,

      the Holders of the Notes or that does not adversely affect the legal
      rights under the Indenture of any such Holder, to comply with the
      requirements of the SEC in order to effect or maintain the qualification
      of the Indenture under the Trust Indenture Act, to make, complete or
      confirm any grant of Collateral permitted or required by the Indenture or
      any of the Security Documents or any release of Collateral that becomes
      effective as set forth in the Indenture and the Security Documents, to
      conform the text of the Indenture, the Subsidiary Guarantees, the Security
      Documents or the Notes to any provision of the Description of Notes in the
      Offering Memorandum to the extent such provision of the Description of
      Notes in the Offering Memorandum was intended to be a verbatim recitation
      of a provision of the Indenture, the Subsidiary Guarantees, the Security
      Documents or the Notes, or to allow any Guarantor to execute a
      supplemental indenture in the form of Exhibit G to the Indenture and/or a
      Note Guarantee with respect to the Notes.

            (12) DEFAULTS AND REMEDIES. Events of Default include: (i) default
      for 30 days in the payment when due of interest or Special Interest, if
      any, on any of the Notes; (ii) default in the payment when due of the
      principal of or premium, if any, on any of the Notes, (iii) failure by the
      Company or any of its Subsidiaries to comply with Section 3.09, 4.10, 4.15
      or 4.19 of the Indenture; (iv) failure by the Company or any of its
      Subsidiaries to observe or perform any other agreement in the Indenture or
      the Security Documents for 30 days after notice to the Company by the
      Trustee or the Holders of at least 25% in aggregate principal amount of
      the Notes then outstanding voting as a single class; (v) default under
      certain other agreements relating to Indebtedness of the Company and its
      Subsidiaries which default is caused by the failure to pay principal of,
      or interest or premium, if any, on, such Indebtedness, or results in the
      acceleration of such Indebtedness prior to its express maturity; (vi)
      final judgments for the payment of money that remain undischarged for a
      period of 60 days, provided the aggregate amount of such judgments exceeds
      $25.0 million (excluding those covered by insurance); (vii) the
      repudiation of the Security Documents by the Company or a Guarantor or the
      unenforceability of the Security Documents under certain circumstances;
      (viii) except as permitted by the Indenture, any Subsidiary Guarantee
      shall be held in any judicial proceeding to be unenforceable or invalid or
      shall cease for any reason to be in full force and effect or any Guarantor
      or any Person acting on its behalf shall deny or disaffirm its obligations
      under such Guarantor's Subsidiary Guarantee; (ix) the breach by any Person
      (other than the Company and its Subsidiaries) of its obligations under, or
      the termination or failure to be in full force of, a Major Project
      Document, unless such breach when taken together with all other such
      breaches would not be materially adverse to the Company and its
      Subsidiaries taken as a whole; and (x) certain events of bankruptcy or
      insolvency with respect to the Company or any of its Significant
      Subsidiaries. If any Event of

                                   EXHIBIT B-8

<PAGE>

      Default occurs and is continuing, the Trustee or the Holders of at least
      25% in aggregate principal amount of the then outstanding Notes may
      declare all the Notes to be due and payable. Notwithstanding the
      foregoing, in the case of an Event of Default arising from certain events
      of bankruptcy or insolvency, all outstanding Notes will become due and
      payable without further action or notice. Holders may not enforce the
      Indenture or the Notes except as provided in the Indenture and the
      Collateral Trust Agreement. Subject to certain limitations, Holders of a
      majority in principal amount of the then outstanding Notes may direct the
      Trustee in its exercise of any trust or power. The Trustee may withhold
      from Holders of the Notes notice of any continuing Default or Event of
      Default (except a Default or Event of Default relating to the payment of
      principal, interest or premium or Special Interest, if any) if it
      determines that withholding notice is in their interest. The Holders of a
      majority in aggregate principal amount of the Notes then outstanding by
      notice to the Trustee may on behalf of the Holders of all of the Notes
      waive any existing Default or Event of Default and its consequences under
      the Indenture except a continuing Default or Event of Default in the
      payment of principal of, or premium, if any, or interest or Special
      Interest, if any, on, the Notes. The Issuers are required to deliver to
      the Trustee annually a statement regarding compliance with the Indenture,
      and the Issuers are required upon becoming aware of any Default or Event
      of Default, to deliver to the Trustee a statement specifying such Default
      or Event of Default.

            (13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
      or any other capacity, may make loans to, accept deposits from, and
      perform services for the Company or its Affiliates, and may otherwise deal
      with the Company or its Affiliates, as if it were not the Trustee.

            (14) NO RECOURSE AGAINST OTHERS. A director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      not have any liability for any obligations of the Company or such
      Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or
      for any claim based on, in respect of, or by reason of, such obligations
      or their creation. Each Holder by accepting a Note waives and releases all
      such liability. This waiver and release are part of the consideration for
      the issuance of the Notes.

            (15) AUTHENTICATION. This Note will not be valid until authenticated
      by the manual signature of the Trustee or an authenticating agent.

            (16) ABBREVIATIONS. Customary abbreviations may be used in the name
      of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN
      ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
      survivorship and not as tenants in common), CUST (= Custodian), and
      U/G/M/A (= Uniform Gifts to Minors Act).

            (17)ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
      RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders
      of Notes under the Indenture, Holders of Restricted Global Notes and
      Restricted Definitive Notes will have all the rights set forth in the
      Registration Rights Agreement, dated as of March 23, 2004 (the
      "Registration Rights Agreement"), among the Company, CalGen Finance, the
      Guarantors and the initial purchaser of the Notes.

            (18) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
      Committee on Uniform Security Identification Procedures, the Company has
      caused CUSIP numbers to be printed on the Notes and the Trustee may use
      CUSIP numbers in notices of redemption as a convenience to Holders. No
      representation is made as to the accuracy of such numbers either as

                                   EXHIBIT B-9

<PAGE>

      printed on the Notes or as contained in any notice of redemption and
      reliance may be placed only on the other identification numbers placed
      thereon.

            (19) NON-RECOURSE. Notwithstanding anything to the contrary set
      forth in the Indenture, this Note, any Security Document or any other Note
      Document, this Note and the Subsidiary Guarantees are non-recourse secured
      obligations of the Company and Guarantors, respectively. The only recourse
      a holder of the Notes will have with respect to the payment of principal
      of, or interest or premium or Special Interest, if any, on, this Note
      (whether under the Indenture or the Note, or pursuant to the Subsidiary
      Guarantees) will be enforcement of its rights against CalGen Finance under
      the Indenture or against the Collateral pursuant to the Security
      Documents.

      The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture, the Registration Rights Agreement and the
Security Documents. Requests may be made to:

                   TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

      SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of 20_,
among_________________________, a______________________(the "Guaranteeing
Subsidiary"), Calpine Generating Company, LLC (the "Company"), CalGen Finance
Corp. ("CalGen Finance" and, together with the Company, the "Issuers"), the
other Guarantors (as defined in the Indenture referred to herein) and Wilmington
Trust FSB, as trustee under the Indenture referred to herein (the "Trustee").

                                   WITNESSETH

      WHEREAS, the Issuers have heretofore executed and delivered to the Trustee
a Second Priority Indenture, dated as of March 23, 2004 (the "Indenture"),
providing for the issuance of an aggregate principal amount of $640.0 million of
Second Priority Secured Floating Rate Notes due 2010 (the "Notes");

      WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Subsidiary Guarantee"); and

      WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

      NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

      1.    CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

      2.    AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to
provide an unconditional Guarantee on the terms and subject to the conditions
set forth in the Note Guarantee and in the Indenture, including but not limited
to Article 11 thereof, and to become bound as a "Guarantor" under the Indenture.

      3.    No RECOURSE AGAINST OTHERS. This Subsidiary Guarantee is a
non-recourse secured obligation of the Subsidiary Guarantor. The only recourse a
Holder of Notes will have under the Subsidiary Guarantee is enforcement of its
rights against the Collateral securing the Subsidiary Guarantee pursuant to the
Security Documents. No past, present or future director, officer, employee,
incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such,
shall have any liability for any obligations of the Company or any Guaranteeing
Subsidiary under the Notes, any Subsidiary Guarantee, the Indenture or this
Supplemental Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of the Notes by accepting a
Note waives and releases all such liability. This waiver and release are part of
the consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
SEC that such a waiver is against public policy.

      4.    NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO

Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

      6.    EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

Debt.

                        [_].2..2. Except for the right to accept payments as

for or accept from the Subordinated Debtor or any other Person any such payment
or collateral, nor take any other action to enforce or collect upon any such
payment or to enforce its rights to receive any such payment, in either case in
respect of the Subordinated Debt, provided, however, that nothing herein shall
limit the right or ability of Junior Claimant (i) to receive payments from the
Subordinated Debtor in respect of the Subordinated Debt as provided in Section
[_].2.1 so long as no default or event of default under any Secured Debt
Document has occurred and is continuing, or (ii) to accelerate the maturity of

                        [__].2.4. Each document or instrument evidencing
Subordinated Debt shall bear a legend providing that payment of the Subordinated
Debt thereunder has been subordinated to prior payment of the Senior Claims in
the manner and to the extent set forth in this Article.

                        [__].2.5. Junior Claimant shall not commence or join
with any other creditor or creditors of the Subordinated Debtor in commencing
any Proceeding against the Subordinated Debtor, [CalGen, CalGen Holdings or any
Guarantor -- ADD ALL THAT ARE NOT SUBORDINATED DEBTORS], but may join in any
Proceeding after it has commenced. At any general meeting of creditors of
Subordinated Debtor, [CalGen, CalGen Holdings or any Guarantor -- ADD ALL THAT
ARE NOT SUBORDINATED DEBTORS], or in the event of any Proceeding, if all Senior
Claims have not been paid in full in cash at such time, the Collateral Agent on
behalf of the Senior Claimants is hereby irrevocably authorized at any such
meeting or in any such Proceeding:

                        (a)   To enforce claims comprising Subordinated Debt in
            the name of Junior Claimant, by proof of debt, proof of claim, suit
            or otherwise;

                        (b)   To collect any assets of the Subordinated Debtor
            distributed, divided or applied by way of dividend or payment as a
            result of a Proceeding, or such securities issued, on account of
            Subordinated Debt as a result thereof and apply the same, or the
            proceeds of any realization upon the same that the Senior Claimants
            in their discretion elect to effect, to Senior Claims until all
            Senior Claims shall have been paid in full in cash (the Senior
            Claimants hereby agreeing to render any surplus to Junior Claimant
            and/or other subordinated creditors, as their interests appear, or
            to interplead such surplus with a court of competent jurisdiction);
            and

                        (c)   To take generally any action in connection with
            any such meeting or proceeding which Junior Claimant might otherwise
            take in respect of the Subordinated Debt and claims relating
            thereto.

                        After the commencement of any such Proceeding, Junior
Claimant may inquire in writing of the Collateral Agent on behalf of the Senior
Claimants whether the respective Senior Claimants intend to exercise the
foregoing rights with respect to the Subordinated Debt. Should the Senior
Claimants fail, at least 20 days before the deadline therefor, either to file a
proof of claim with respect to the Subordinated Debt and to furnish a copy
thereof to Junior Claimant, or to inform Junior Claimant in writing that the
Senior Claimants intend to exercise their rights to assert the Subordinated Debt
in the manner hereinabove provided, Junior Claimant may, but shall not be
required to, proceed to file a proof of claim with respect to the Subordinated
Debt and take such further steps with respect thereto, not inconsistent with
this Article, as Junior Claimant may deem proper.

                        [__].2.6. Upon the occurrence and during the
continuation of an event of default under a Secured Debt Document, Junior
Claimant may, but shall have no obligation to, upon not less than 10 days prior
written notice to the Collateral Agent, purchase all of the outstanding Senior
Obligations owing to the Senior Claimants by irrevocably tendering, in
immediately available funds, full payment of the Purchase Price (as defined
below) to the Senior Claimants:

                        (a)   The Purchase Price shall be equal to the total
            amount of Senior Claims at the time of acceleration (assuming such
            obligations have been accelerated);

                                   EXHIBIT H-3

<PAGE>

                        (b)   Any such purchase by Junior Claimant shall be
            without warranty by, or recourse to, the Senior Claimants, except
            with respect to the legal and beneficial ownership by the Senior
            Claimants of the Obligations so purchased, free and clear of all
            Liens and rights of others; and

                        (c)   Concurrently with any such purchase, the Senior
            Claimants shall forthwith sell, assign, transfer and convey to
            Junior Claimant all of their right, title and interest in and to the
            Senior Obligations, and all Liens and other security interests in
            favor of the Senior Claimants securing the obligations of the
            Subordinated Debtor in connection therewith.

            Section [__].3. Senior Claim Documents. The Junior Claimant
acknowledges that it has been provided with a copy of the Senior Claim Documents
and has read and is familiar with the provisions thereof.

            Section [__].4. Time of Filing. Notwithstanding the time of filing,
attachment or recording of any document or other instrument, it is agreed by
Junior Claimant that any Liens arising under or pursuant to the Senior Claim
Documents shall be senior to any Liens arising in favor of Junior Claimant as
part of or relating to the Subordinated Debt Documents, if any; provided,
however, that nothing herein shall be deemed to permit Junior Claimant to obtain
any such Liens.

            Section [__].5. Wrongful Collections. Should any payment on account
of, or any collateral for any part of, the Subordinated Debt be received by
Junior Claimant in violation of this Article, such payment or collateral shall
be delivered forthwith to the Collateral Agent by the recipient for application
to Senior Claims, in the form received. The Collateral Agent is irrevocably
authorized to supply any required endorsement or assignment which may have been
omitted. Until so delivered, any such payment or collateral shall be held by the
recipient in trust for the Senior Claimants and shall not be commingled with
other funds or property of the recipient.

            Section [__].6. Ownership of Subordinated Debt; Amendment of
Subordinated Debt Documents.

                        [__].6.1. The Junior Claimant represents and warrants
that it is the lawful owner of the Subordinated Debt. Any security interest in
the Junior Claimant's interest in the Subordinated Debt will at all times be
subject to the rights of the Senior Claimants hereunder. The Junior Claimant
agrees that it may not assign all or any portion of the Subordinated Debt or any
of its rights or remedies under the Subordinated Debt Documents unless any
assignee expressly agrees in writing for the benefit of the Collateral Agent
that it takes such Subordinated Debt subject in all respects to the rights of
the Senior Claimants hereunder.

                        [__].6.2. The Subordinated Debt Documents may not be
amended so as to have an adverse effect upon the Senior Claims or the
Subordinated Debtor's ability to pay the Senior Claims at any time.

            Section [__].7. Waivers. The Collateral Agent and the Senior
Claimants are hereby authorized to demand specific performance of this Article,
whether or not the Subordinated Debtor shall have complied with the provisions
hereof applicable to it, at any time when Junior Claimant shall have failed to
comply with any provision hereof applicable to it. Junior Claimant hereby
irrevocably waives any defense based on the adequacy of a remedy at law which
might be asserted as a bar to the remedy of specific performance hereof in any
action brought therefor by the Senior Claimants. Junior Claimant (a) further
waives presentment, notice and protest in connection with all negotiable
instruments

                                   EXHIBIT H-4

<PAGE>

evidencing Senior Claims or Subordinated Debt to which Junior Claimant may be a
party, notice of the acceptance of this Article by the Senior Claimants, notice
of any loan made, extension granted or other action taken in reliance hereon,
and all demands and notices of every kind in connection with this Article,
Senior Claims or time of payment of Senior Claims or Subordinated Debt and (b)
hereby assents to any renewal, extension or postponement of the time of payment
of Senior Claims or any other indulgence with respect thereto, to any increase
in the amount of Senior Claims, to any substitution, exchange or release of
collateral therefor and to the addition or release of any person primarily or
secondarily liable thereon and assents to the provisions of any instrument,
security or other writing evidencing Senior Claims.

            Section [__].8. Subrogation; No Impairment of Subordinated Debtor's
Obligations. Subject to and from and after the Senior Obligations Termination
Date, Junior Claimant shall be subrogated to the rights of the Senior Claimants
to receive payments or distributions of cash, property or securities of the
Subordinated Debtor applicable to the Senior Claims until all amounts owing on
the Subordinated Debt shall be paid in full. For purposes of such subrogation,
no payments or distributions to the Senior Claimants to which Junior Claimant
would be entitled but for the provisions of this Article, and no payments paid
over by Junior Claimant to Senior Claimants pursuant to this Article shall, as
among the Subordinated Debtor, its creditors other than the Senior Claimants,
and Junior Claimant, be deemed to be a payment or distribution on account of the
Subordinated Debt, it being understood that the provisions of this Article are
intended solely for the purpose of defining the relative rights of Junior
Claimant and the Senior Claimants. Nothing contained in this Article is intended
to or shall impair, as between the Subordinated Debtor and Junior Claimant, the
obligation of the Subordinated Debtor, which is absolute and unconditional, to
pay to Junior Claimant the principal of and the premium, if any, and the
interest on the Subordinated Debt, and all other amounts payable by the
Subordinated Debtor under the Subordinated Debt Documents, as and when the same
shall become due and payable, or to affect the relative rights of Junior
Claimant and creditors of Subordinated Debtor other than the Senior Claimants.

            Section [__].9. Reinstatement. The obligations of Junior Claimant
under this Article shall continue to be effective, or be reinstated, as the case
may be, if at any time any payment in respect of any Senior Claim, or any other
payment to any holder of any Senior Claim in its capacity as such, is rescinded
or must otherwise be restored or returned by the holder of such Senior Claims
upon the occurrence of any Proceeding, or upon or as a result of the appointment
of a receiver, intervenor or conservator of, or trustee or similar officer for,
the Subordinated Debtor or any substantial part of its property, or otherwise,
all as though such payment had not been made.

            Section [__].10. Bankruptcy. This Article shall remain in full force
and effect as between Junior Claimant and the Senior Claimants notwithstanding
the occurrence of any Proceeding affecting the Subordinated Debtor.

            Section [__].11. Further Assurances. The Subordinated Debtor and
Junior Claimant shall execute and deliver to the Senior Claimants such further
instruments and shall take such further action as the Senior Claimants may at
any time or times reasonably request in order to carry out the provisions and
intent of this Article.

            Section [__].12. Successors and Assigns. The provisions of this
Article shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns. Neither Junior Claimant nor the Senior
Claimants shall have a duty to preserve rights against prior parties in any
property of any kind received hereunder. Nothing contained herein shall impose
on the Senior Claimants any duties with respect to any property of the
Subordinated Debtor or Junior Claimant received hereunder.

            Section [__].13. Governing Law. This Article is intended to take
effect as a sealed instrument, shall be binding upon the parties hereto and
their respective executors, administrators, other legal representatives,
successors and assigns, and shall inure to the benefit of the Senior Claimants,
their respective successors and assigns and shall be governed by the laws of the
State of New York without reference to principles of conflict of laws (other
than Section 5-1401 of the New York General Obligations Law). The parties hereto
intend and agree that this Article shall remain binding on such parties (other
than the Subordinated Debtor) notwithstanding the termination (except upon the
payment in full of Senior Claims in cash) or unenforceability of this Article as
against the Subordinated Debtor.
