              (1) Indebtedness of any other Person existing at the time such
         other Person is merged with or into or became a Restricted Subsidiary

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or interest on the Notes, and shall notify the
Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) shall have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent for
the Notes.

Section 2.05      Holder Lists.

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

be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the

                                       32



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. All Global Notes shall be exchanged by the Company for Definitive
Notes if:

                  (1)      the Company delivers to the Trustee 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 Company within 120 days after the date of such notice
         from the Depositary; or

                  (2)      the Company in its sole discretion determines that
         the Global Notes (in whole but not in part) should be exchanged for
         Definitive Notes and delivers a written notice to such effect to the
         Trustee.

         Upon the occurrence of either of the preceding events in (1) or (2)
above, Definitive Notes shall be issued in such names as the Depositary shall
instruct the Trustee. Global Notes also may be exchanged or replaced, in whole
or in part, as provided in Sections 2.07 and 2.10 hereof. 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 hereof,
shall be authenticated by the Trustee pursuant to an Authentication Order 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) hereof.

         (b)      Transfer and Exchange of Beneficial Interests in the Global
Notes. The transfer and exchange of beneficial interests in the Global Notes
shall be effected through the Depositary, in accordance with the provisions of
this Indenture and the Applicable Procedures. Beneficial interests in the
Restricted Global Notes shall 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 shall 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 expiration of the
         Restricted Period, transfers of beneficial interests in the Regulation
         S Global Note may not be made to a U.S. Person or for the account or
         benefit of a U.S. Person (other than an Initial Purchaser). 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 both:

                  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

                           (B)      instructions given in accordance with the
                  Applicable Procedures containing information regarding the

                  (3)      Transfer of Beneficial Interests to Another
         Restricted Global Note. A beneficial interest in any Restricted Global
         Note may be transferred to a Person who takes delivery thereof in the
         form of a beneficial interest in another Restricted Global Note if the
         transfer complies with the requirements of Section 2.06(b)(2) above and
         the Registrar receives the following:

         similar governmental charge payable upon exchange or transfer pursuant
         to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

                  (3)      The Registrar shall 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.

         registration of transfer or exchange of Global Notes or Definitive
         Notes shall be the valid obligations of the Company, 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 Company shall 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 hereof 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 Company 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 Notes and for all other purposes, and
         none of the Trustee, any Agent or the Company shall be affected by
         notice to the contrary.

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

                  (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.

                                       38



Section 2.07      Replacement Notes.

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

         Every replacement Note is an additional obligation of the Company and
shall 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 hereof, 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 hereof, 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 hereof, it ceases to be outstanding and interest on it ceases to accrue.

         If the Paying Agent (other than the Company, a Subsidiary 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 shall be deemed to be no longer outstanding and shall 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, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned shall be so disregarded.

Section 2.10      Temporary Notes.

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

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

                                       39



Section 2.11      Cancellation.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes in accordance with its customary practices (subject to the record
retention requirement of the Exchange Act). Certification of the destruction of
all canceled Notes shall be delivered to the Company. The Company may not issue
new Notes to replace Notes that it has 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 shall
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 hereof. The Company shall 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 shall 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) shall 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 3.01      Notices to Trustee.

         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 but not more than 60 days before a redemption date, an Officers'
Certificate setting forth:

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

                  (2)      the redemption date;

                  (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 shall select Notes for redemption or
purchase as follows:

                  (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 the Notes are not listed on any national
         securities exchange, on a pro rata basis, by lot or by such method as
         the Trustee shall deem fair and appropriate.

                                       40



         In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased shall 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 shall 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 shall 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 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
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 Articles 8 or 11, respectively, of this
Indenture.

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

                  (1)      the redemption date;

                  (2)      the redemption price;

                  (3)      if any Note is being redeemed in part, 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 shall 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 Company defaults 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 shall 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

                                       41



days prior to the redemption date, an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such
notice as provided in the preceding paragraph.

Section 3.04      Effect of Notice of Redemption.

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, 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 Company shall deposit with the Trustee or with the Paying Agent
money sufficient to pay the redemption or purchase price of and accrued interest
on all Notes to be redeemed or purchased on that date. The Trustee or the Paying
Agent shall promptly return to the Company any money deposited with the Trustee
or the Paying Agent by the Company in excess of the amounts necessary to pay the
redemption or purchase price of, and accrued interest on, all Notes to be
redeemed or purchased.

         If the Company complies with the provisions of the preceding paragraph,
on and after the redemption or purchase date, interest shall 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 to the Person in whose name such Note was registered at the close of
business on such record date. If any Note called for redemption or purchase is
not so paid upon surrender for redemption or purchase because of the failure of
the Company 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
hereof.

Section 3.06      Notes Redeemed or Purchased in Part.

         Upon surrender of a Note that is redeemed or purchased in part, the
Company shall issue and, upon receipt of an Authentication Order, the Trustee
shall 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.

Section 3.07      Optional Redemption.

         (a)      At any time prior to July 15, 2006, the Company may on one or
more occasions upon not less than 30 nor more than 60 days prior notice mailed
by first-class mail to each holder's registered address, redeem up to 35% of the
aggregate principal amount of Notes issued under this Indenture at a redemption
price of 108.750% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the redemption date, with the net cash proceeds of one or
more Public Equity Offerings; provided that:

         held by the Company and its Subsidiaries); and

                  (2)      the redemption must occur within 45 days of the date
         of the closing of such Public Equity Offering.

sinking fund payments with respect to the Notes.

Section 3.09      Offer to Purchase by Application of Excess Proceeds.

         In the event that, pursuant to Section 4.10 hereof, the Company is
required to commence an offer to all Holders to purchase Notes (an "Asset Sale
Offer"), it shall follow the procedures specified below.

         The Asset Sale Offer shall be made to all Holders and all holders of
other Indebtedness that is pari passu with the Notes containing provisions
similar to those set forth in this Indenture with respect to offers to purchase
or redeem with the proceeds of sales and assets. The Asset Sale Offer shall
remain open for a period of at least 20 Business Days following its commencement
and not more than 30 Business Days, except to the extent that a longer period is
required by applicable law (the "Offer Period"). No later than three Business
Days after the termination of the Offer Period (the "Purchase Date"), the
Company shall apply all Excess Proceeds (the "Offer Amount") to the purchase of
Notes and such other pari passu Indebtedness (on a pro rata basis, if
applicable) or, if less than the Offer Amount has been tendered, all Notes and
other Indebtedness tendered in response to the Asset Sale Offer. Payment for any
Notes so purchased shall be made in the same manner as interest payments are
made.

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

         Upon the commencement of an Asset Sale Offer, the Company shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The written notice shall contain

                                       43



all instructions and materials necessary to enable such Holders to tender Notes
pursuant to the Asset Sale Offer. The written notice, which shall govern the
terms of the Asset Sale Offer, shall state:

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

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

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

                  (4)      that, unless the Company defaults in making such
         payment, any Note accepted for payment pursuant to the Asset Sale Offer
         shall 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 shall 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, a Depositary, if appointed by the Company, or a Paying
         Agent at the address specified in the notice at least three days before
         the Purchase Date;

                  (7)      that Holders shall be entitled to withdraw their
         election if the Company, the Depositary or the Paying Agent, as the
         case may be, receives, not later than the expiration of the Offer
         Period, a telegram, telex, facsimile transmission or letter setting
         forth the name of the Holder, the principal amount of the 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 pari passu Indebtedness surrendered by Holders exceeds the Offer
         Amount, the Company shall select the Notes and other pari passu
         Indebtedness to be purchased on a pro rata basis based on the principal
         amount of Notes and such other pari passu Indebtedness surrendered
         (with such adjustments as may be deemed appropriate by the Company so
         that only Notes in denominations of $1,000, or integral multiples
         thereof, shall be purchased); and

                  (9)      that Holders whose Notes were purchased only in part
         shall 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 Company will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes tendered, and
shall deliver to the Trustee an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Company in accordance with the
terms of this Section 3.09. The Company, either directly or through the
Depositary or the Paying Agent, as the case may be, shall promptly (but in any
case not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by
such Holder and accepted by the Company for purchase, and the Company shall
promptly issue a new Note, and the Trustee, upon written request from the
Company and receipt of an Authentication Order shall authenticate and mail or
deliver such new Note

                                       44



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 Company to the Holder thereof. The Company shall publicly announce the
results of the Asset Sale Offer on the Purchase Date.

         Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

Section 4.01      Payment of Notes.

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

holds as of 10:00 a.m. Eastern Time on the due date money deposited by the
Company in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due.

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 shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of 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 shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where 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 shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
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 shall 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 shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

         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
hereof.

                  (1)      all quarterly and annual reports that would be
         required to be filed with the Commission 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

regulations applicable to such reports (unless the Commission shall not accept
such a filing) and make such information available to securities analysts and
prospective investors upon request.

         (c)      If, at any time, the Company is no longer subject to the
periodic reporting requirements of the Exchange Act for any reason, the Company
shall nevertheless continue filing the reports specified in Section 4.03(a) with
the Commission within the time periods specified above unless the Commission
shall not accept such a filing. The Company agrees that it shall not take any
action for the purpose of causing the Commission not to accept any such filings.

Section 4.03(a) on its website within the time periods that would apply if the
Company were required to file those reports with the Commission.

results of operations of the Unrestricted Subsidiaries of the Company.

         (e)      In addition, the Company agrees that, for so long as any Notes
remain outstanding, at any time it is not required to file the reports required

securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.

Section 4.04      Compliance Certificate.

         (a)      The Company and each Guarantor (to the extent that such

Company has kept, observed, performed and fulfilled its obligations under this
Indenture and the Security Documents, and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge the
Company has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and the Security Documents and is not in default in
the performance or observance of any of the terms, provisions and conditions of
this Indenture or the Security Documents (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,

                                       46

of the event and what action the Company is taking or proposes to take with
respect thereto.

         (b)      So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof 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 shall
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event

where the failure to effect such payment is not adverse in any material respect
to the Holders of the Notes.

Section 4.06      Stay, Extension and Usury Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it shall not at any time insist upon, plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

Section 4.07      Restricted Payments.

         (a)      The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly:

         or distribution on account of the Company's or any of its Restricted
         Subsidiaries' Equity Interests (including any payment in connection
         with any merger or consolidation involving the Company or any of its
         Restricted Subsidiaries) or to the direct or indirect holders of the
         Company's or any of its Restricted Subsidiaries' Equity Interests in

                                       47



                  (3)      make any payment on or with respect to, or purchase,
         redeem, defease or otherwise acquire or retire for value any
         Indebtedness of the Company that is contractually subordinated to the
         Notes (excluding any intercompany Indebtedness between or among the
         Company and any of its Restricted Subsidiaries and excluding the
         purchase, repurchase or other acquisition of such subordinated
         Indebtedness purchased in anticipation of satisfying a sinking fund
         obligation, principal installment or final maturity, in each case due
         within one year of the date of acquisition), except a payment of
         interest or principal at the Stated Maturity thereof; or

                  (4)      make any Restricted Investment

above being collectively referred to as "Restricted Payments"), unless after
giving effect to such Restricted Payment:

                  (1)      no Default or Event of Default has occurred and is
         continuing or would occur as a consequence of such Restricted Payment
         (other than any Default or Event of Default that is cured as a result
         of such Restricted Payment);

                  (2)      the Company would, after giving pro forma effect
         thereto as if such Restricted Payment had been made at the beginning of
         the applicable four-quarter period, have been permitted to incur at
         least $1.00 of additional Indebtedness pursuant to the Fixed Charge
         Coverage Ratio test set forth in Section 4.09(a) herein; and

                  (3)      such Restricted Payment, together with the aggregate
         amount of all other Restricted Payments made by the Company and its
         Restricted Subsidiaries since the date of this Indenture (excluding
         Restricted Payments permitted by clauses (2), (3), (4), (5), (6), and
         (9) of the next succeeding paragraph), is less than the sum, without
         duplication, of:

         Company for the period (taken as one accounting period) from the
         beginning of the first fiscal quarter commencing after the date of this
         Indenture to the end of the Company's most recently ended fiscal
         quarter for which internal financial statements are available at the
         time of such Restricted Payment (or, if such Consolidated Net Income
         for such period is a deficit, less 100% of such deficit), plus

                           (b)      100% of the aggregate net cash proceeds
         received by the Company since the date of this Indenture as a
         contribution to its common equity capital or from the issue or sale of
         Equity Interests of the Company (other than Disqualified Stock) or from
         the issue or sale of convertible or exchangeable Disqualified Stock or
         convertible or exchangeable debt securities of the Company that have

         Subsidiary of the Company), plus

                           (c)      to the extent that any Restricted Investment
         that was made after the date of this Indenture is sold for cash or
         otherwise liquidated or repaid for cash, the lesser of (i) the cash
         return of capital with respect to such Restricted Investment (less the
         cost of disposition, if any) and (ii) the initial amount of such
         Restricted Investment, plus

                           (d)      to the extent that any Unrestricted
         Subsidiary of the Company designated as such after the date of this
         Indenture is redesignated as a Restricted Subsidiary after the date of
         this Indenture, the Fair Market Value of the Company's Investment in
         such Subsidiary as of the date of such redesignation, plus

                                       48

         Indebtedness, dividends, repayments of loans or advances, or other
         transfers of assets received by the Company or a Restricted Subsidiary
         of the Company after the date of this Indenture from an Unrestricted
         Subsidiary of the Company, to the extent that such payments, dividends,
         repayments or transfers were not otherwise included in Consolidated Net
         Income of the Company for such period, plus

                           (f)      $628.3 million.

                  The preceding provisions shall not prohibit:

                  (1)      the payment of any dividend within 60 days after the
         date of declaration of the dividend, if at the date of declaration the
         dividend payment would have complied with the provisions of this
         Indenture;

                  (2)      the making of any Restricted Payment in exchange for,

         (other than to a Subsidiary of the Company) of, Equity Interests of the
         Company (other than Disqualified Stock) or from the substantially
         concurrent contribution of common equity capital to the Company;
         provided that the amount of any such net cash proceeds that are
         utilized for any such Restricted Payment shall be excluded from clause
         (3)(b) of the preceding paragraph;

                  (3)      the defeasance, redemption, repurchase or other
         acquisition of Indebtedness of the Company that is contractually
         subordinated to the Notes with the net cash proceeds from a
         substantially concurrent incurrence of Permitted Refinancing
         Indebtedness, so long as no Default has occurred and is continuing or
         would be caused thereby;

                  (4)      the payment of any dividend (or, in the case of any
         partnership or limited liability company, any similar distribution) by

         basis;

                  (5)      the repurchase, redemption or other acquisition or

         Subsidiaries) pursuant to any equity subscription agreement, stock
         option agreement, shareholders' agreement or similar agreement;
         provided that the aggregate price paid for all such repurchased,
         redeemed, acquired or retired Equity Interests may not exceed $5.0

         acquisition or retirement for value of subordinated Indebtedness upon a
         Change of Control or an Asset Sale to the extent required by this
         Indenture or other agreement pursuant to which such subordinated

         Sale, has applied the Net Proceeds from such Asset Sale in accordance
         with the provisions described under Section 4.10 herein, so long as no
         Default has occurred and is continuing or would be caused thereby.

         (b)      The amount of all Restricted Payments (other than cash) shall
be the Fair Market Value on the date of the Restricted Payment of the asset(s)

         Indebtedness being refinanced;

                  (8)      Liens securing Indebtedness otherwise permitted to be

         one time outstanding under this clause (1) (with letters of credit
         being deemed to have a principal amount equal to the maximum potential
         liability of the Company thereunder) not to exceed on any date of
         incurrence the greater of (A) $500.0 million or (B) the dollar amount
         that is equal to 50% of the Company's Consolidated Cash Flow for the
         then most recent four-quarter period for which financial information is
         available;

                  (2)      the incurrence by the Company and its Restricted
         Subsidiaries of the Existing Indebtedness;

         Indenture, and in each case the related Guarantees;

                  (4)      the incurrence by the Company or any of its
         Restricted Subsidiaries of Indebtedness represented by Capital Lease
         Obligations, mortgage financings or purchase money obligations, in each
         case, incurred for the purpose of financing all or any part of the
         purchase price or cost of design, construction, installation or
         improvement of property, plant or equipment used in the business of the
         Company or any of its Restricted Subsidiaries, in an aggregate
         principal amount (or accreted value, as applicable), including all
         Permitted Refinancing Indebtedness incurred to extend, refund,
         refinance, renew, replace or defease any Indebtedness incurred pursuant
         to this clause (4), not to exceed $100.0 million at any one time
         outstanding;

                  (5)      Indebtedness of the Company which is owed to and
         owned by a Restricted Subsidiary and Indebtedness of a Restricted
         Subsidiary that is owed to and owned by the Company or a Restricted
         Subsidiary; provided that any subsequent issuance or transfer of any
         Capital Stock that results in any such Restricted Subsidiary ceasing to
         be a Restricted Subsidiary or any transfer of such Indebtedness (other
         than to the Company or a Restricted Subsidiary) shall be deemed, in
         each case, to constitute the incurrence of such Indebtedness by the
         Company or by a Restricted Subsidiary, as the case may be;

                  (6)      the incurrence of Non-Recourse Debt by any Restricted
         Subsidiary of the Company (other than a Restricted Subsidiary that
         owns, directly or indirectly, any Material Designated Assets);

                  (7)      the issuance of preferred stock by a Restricted
         Subsidiary of the Company (other than a Restricted Subsidiary that
         owns, directly or indirectly, any Material Designated Assets), the net
         proceeds of which are applied to finance the exploration, drilling,
         development, construction or purchase of or by, or repairs or
         improvements or additions to, property or assets of the Company or any
         Restricted Subsidiary;

                                       52



                  (8)      the incurrence by the Company of Guarantees of
         Indebtedness of Restricted Subsidiaries which, but for such Guarantees,
         would be permitted to be incurred pursuant to clause (6) of Section
         4.09 (b); provided that the aggregate principal amount of Indebtedness
         incurred pursuant to this clause (8) does not exceed $100.0 million at
         any one time outstanding;

                  (9)      the incurrence by the Company or any of its
         Restricted Subsidiaries of Permitted Refinancing Indebtedness in
         exchange for, or the net proceeds of which are used to refund,
         refinance, replace, defease or discharge Indebtedness (other than
         intercompany Indebtedness) that was permitted by this Indenture to be
         incurred under Section 4.09(a) or clauses (2), (3), (4), (5), (6), (8)
         or (10) of this Section 4.09(b) or this clause (9);

                  (10)     the incurrence of Acquired Debt by any Restricted
         Subsidiary of the Company at the time such Restricted Subsidiary
         becomes a Restricted Subsidiary of the Company so long as such Acquired
         Debt was not incurred in connection with or in contemplation of such
         Person becoming a Restricted Subsidiary of the Company; provided that
         the Company would have been able to incur such Indebtedness at the time
         of incurrence thereof by the Restricted Subsidiary pursuant to Section
         4.09 (a);

                  (11)     the incurrence of Indebtedness pursuant to Hedging
         Obligations incurred in the ordinary course of business and not for
         speculative purposes;

                  (12)     the incurrence by the Company or any of its
         Restricted 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;

                  (13)     the incurrence by the Company or any of its
         Restricted 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;

                  (14)     the incurrence by any Restricted Subsidiary of
         Indebtedness represented by letters of credit (or Guarantees thereof)
         entered into in the ordinary course of business to the extent that such
         letters of credit are not drawn upon or, if and to the extent drawn
         upon, such drawing is reimbursed no later than the tenth Business Day
         following a demand for reimbursement following payment on the letter of
         credit; provided that such letters of credit shall not constitute
         Permitted Debt pursuant to this clause (14) if they are issued in
         support of Indebtedness;

                  (15)     the incurrence of Indebtedness by the Company
         represented by letters of credit cash collateralized with the proceeds
         of Priority Lien Debt; and

                  (16)     the incurrence by the Company or any of its
         Restricted Subsidiaries of additional Indebtedness in an aggregate
         principal amount (or accreted value, as applicable) at any time
         outstanding, including all Permitted Refinancing Indebtedness incurred
         to extend, refinance, renew, replace, defease or refund any
         Indebtedness incurred pursuant to this clause (16), not to exceed
         $100.0 million.

         The Company shall not incur and shall not permit any Guarantor to
incur, any Indebtedness (including Permitted Debt) that is contractually
subordinated in right of payment to any other Indebtedness of the Company or
such Guarantor unless such Indebtedness is also contractually subordinated in
right of payment to the Notes (and the Applicable Guarantee) and the Term Loans
on

                                       53



substantially identical terms; provided, however, that no Indebtedness of the
Company shall be deemed to be contractually subordinated in right of payment to
any other Indebtedness of the Company solely by virtue of being unsecured or by
virtue of being secured on a junior basis.

Section 4.10      Asset Sales.

         (a)      The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale (including a Sale of
Designated Assets) unless:

                  (1)      the Company (or the Restricted Subsidiary, 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 75% of the consideration received in the
         Asset Sale by the Company or such Restricted Subsidiary is in the form
         of cash or Cash Equivalents. For purposes of this provision, each of
         the following shall be deemed to be cash:

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

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

                           (C)      except in the case of a Sale of Designated
                  Assets, any stock or assets of the kind referred to in clauses
                  (4) or (6) of Section 4.10(b); and

                  (3)      in the case of a Sale of Designated Assets other than
         Canadian Gas Assets, the Company (or the Restricted Subsidiary, as the
         case may be) shall deposit the Net Proceeds as cash collateral in a
         segregated account (a "Designated Asset Sale Proceeds Account") held by
         the Collateral Trustee or its agent to secure the Secured Obligations;
         provided, that for so long as the terms of any of the Company's senior
         unsecured notes that were issued prior to August 10, 2000 would prevent
         such a pledge by a Restricted Subsidiary, the Company shall deposit
         with the Collateral Trustee or its agent an amount of cash equal to the
         Net Proceeds as cash collateral to secure the Secured Obligations, and
         the applicable Restricted Subsidiary shall not be obligated to do so.

         (b)      Within 365 days after the receipt of any Net Proceeds from an
Asset Sale, other than a Sale of Designated Assets that are not Canadian Gas
Assets, the Company (or the applicable Restricted Subsidiary, as the case may
be) may apply those Net Proceeds:

                  (1)      to repay Priority Lien Debt and/or cash collateralize
         letters of credit constituting Priority Lien Debt;

                  (2)      in the case of an Asset Sale by a Restricted
         Subsidiary, to repay or repurchase Indebtedness of Calpine Canada
         Energy Finance ULC and/or Calpine Canada Energy Finance II ULC existing
         on the date of this Indenture;

                                       54



                  (3)      in the case of an Asset Sale by a Restricted
         Subsidiary, to repay or repurchase Indebtedness of any Restricted
         Subsidiary and, if such Indebtedness is revolving credit Indebtedness,
         to correspondingly reduce commitments with respect thereto;

                  (4)      to acquire all or substantially all of the assets of,
         or any Capital Stock of, another Permitted Business, if, after giving
         effect to any such acquisition of Capital Stock, the Permitted Business
         is or becomes a Restricted Subsidiary of the Company;

                  (5)      to make a capital expenditure; or

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

         (c)      Within 180 days after the receipt of any Net Proceeds from an
Asset Sale that constitutes a Sale of Designated Assets other than Canadian Gas
Assets, the Company (or the Restricted Subsidiary that disposed of those
Designated Assets, as the case may be) may apply those Net Proceeds to purchase
other assets that would constitute Designated Assets or to repay Priority Lien
Debt and/or cash collateralize letters of credit constituting Priority Lien Debt
and, if such Priority Lien Debt is revolving credit Indebtedness, to
correspondingly reduce commitments with respect thereto.

         (d)      Any Net Proceeds from Asset Sales (including Sales of
Designated Assets) that are not applied or invested as provided in the preceding
clauses of this Section 4.10 shall constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $50.0 million, or at such earlier
point as may be elected by the Company, the Company shall make an offer to all
holders of the Notes and all holders of other Indebtedness that is pari passu
with the Notes and equally and ratably secured with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers
to purchase or redeem with the proceeds of sales of assets, including the 2007
Notes, the 2010 Notes, the Term Loans and each series of Existing Indebtedness
that contains similar asset sale provisions, when applicable (an "Asset Sale
Offer"), to purchase or redeem the maximum principal amount of notes and such
other pari passu Indebtedness that may be purchased or redeemed out of the
Excess Proceeds (including each series of Existing Indebtedness that contains
similar asset sale provisions). The offer price in any Asset Sale Offer shall be
equal to 100% of principal amount plus accrued and unpaid interest, if any, to
the date of purchase, and shall be payable in cash. If any Excess Proceeds
remain after consummation of an Asset Sale Offer, the Company may use those
Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If
the aggregate principal amount of notes and other pari passu Indebtedness
tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the
Company shall select the Notes and such other pari passu Indebtedness to be
purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero.

         (e)      Notwithstanding the foregoing, to the extent that any or all
of the Net Proceeds of any Foreign Asset Sale is prohibited or delayed by
applicable local law from being repatriated to the United States, the portion of
such Net Proceeds so affected shall not be required to be applied at the time
provided above, but may be retained by the applicable Restricted Subsidiary so
long, but only so long, as the applicable local law shall not permit
repatriation to the United States. The Company shall promptly take or cause the
applicable Restricted Subsidiary to promptly take all actions required by the
applicable local law to permit such repatriation. Once such repatriation of any
of the affected Net Proceeds is permitted under the applicable local law, the
repatriation shall be immediately effected and the repatriated Net Proceeds
shall be applied in the manner set forth in this Section 4.10 as if the Asset
Sale had occurred on the date of such repatriation.

                                       55



         (f)      Notwithstanding the foregoing, to the extent that the Board of
Directors determines, in good faith, that repatriation of any or all of the Net
Proceeds of any Foreign Asset Sale would have a material adverse tax consequence
to the Company, the Net Proceeds so affected may be retained outside of the
United States by the applicable Restricted Subsidiary for so long as such
material adverse tax consequence would continue.

         (g)      The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent 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 Asset Sale
provisions of this Indenture, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the Asset Sale provisions of this Indenture by virtue of such
conflict.

Section 4.11      Transactions with Affiliates.

         (a)      The Company shall not, and shall not permit any of its
Restricted 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 is on terms that are no
         less favorable to the Company or the relevant Restricted Subsidiary
         than those that would have been obtained in a comparable transaction by
         the Company or such Restricted Subsidiary with an unrelated Person; and

                  (2)      the Company delivers to the Trustee:

                           (a)      with respect to any Affiliate Transaction or
         series of related Affiliate Transactions involving aggregate
         consideration in excess of $2.5 million, an officers' certificate
         certifying that such Affiliate Transaction complies with this Section
         4.11(a); and

                           (b)      with respect to any Affiliate Transaction or
         series of related Affiliate Transactions involving aggregate
         consideration in excess of $10.0 million, a resolution of the Board of
         Directors set forth in an officers' certificate certifying that such
         Affiliate Transaction complies with this Section 4.11 and that such
         Affiliate Transaction has been approved by a majority of the
         disinterested members of the Board of Directors or, if there are no
         disinterested members of the Board of Directors, the Board of Directors
         shall have received a written opinion of an accounting, appraisal or
         investment banking firm of national standing stating that such
         Affiliate Transaction or series of Affiliate Transactions is fair to
         the Company or such Restricted Subsidiary from a financial point of
         view.

         (b)      The following items shall not be deemed to be Affiliate
Transactions and, therefore, shall not be subject to the provisions of Section
4.11(a):

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

                  (2)      transactions between or among the Company and its
         Restricted Subsidiaries and between or among the Company's Restricted
         Subsidiaries;

                                       56



                  (3)      transactions with a Person (other than an
         Unrestricted Subsidiary of the Company) that is an Affiliate of the
         Company solely because the Company owns, directly or through a
         Restricted 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;

                  (6)      Restricted Payments that do not violate the
         provisions of Section 4.07 hereof;

                  (7)      loans or advances to employees in the ordinary course
         of business;

                  (8)      any repurchase, redemption or other retirement of
         Capital Stock of the Company held by employees of the Company or any of
         its Subsidiaries upon death, disability or termination of employment at
         a price not in excess of the Fair Market Value thereof approved by the
         Board of Directors;

                  (9)      any transaction between or among the Company and any
         of its Subsidiaries in the ordinary course of business and consistent
         with past practices of the Company and its Subsidiaries; and

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

         (c)      Any transaction which has been determined, in the written
opinion of an independent nationally recognized investment banking firm, to be
fair, from a financial point of view, to the Company or the applicable
Restricted Subsidiary shall be deemed to be in compliance with this Section
4.11.

Section 4.12      Liens.

         (a)      The Company shall not, and shall not permit any of its
Restricted 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.

         (b)      The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, grant or permit to exist a Lien upon any property
(whether then held by it or to be acquired by it at a future time) as security
for any Priority Lien Debt, unless (1) such Lien secures all Priority Lien Debt
on an equal and ratable basis and (2) the Collateral Trustee holds an
enforceable and perfected Lien upon such property as security equally and
ratably for all Parity Lien Obligations in second priority to Priority Lien
Debt.

Section 4.13      Limitation on Changes in the Nature of the Business.

         The Company and its Restricted Subsidiaries shall engage only in
Permitted Businesses, except to such extent as would not be material to the
Company and its Restricted Subsidiaries taken as a whole. In addition, the
Company will, and shall cause its Subsidiaries, to conduct their respective
businesses in a manner so as to maintain the exemption of the Company and its
Subsidiaries from treatment as a public utility holding company under PUHCA or
an electric utility or public utility under any federal, state or local law;
provided to the extent that any such law is amended following the date of this
Indenture in such a manner that would (absent application of this proviso) make
non-compliance with this Section 4.13 not result in a material adverse effect on
the Company's results of operations or financial condition, then the

                                       57



Company shall not be required to comply with this Section 4.13, but only to the
extent of actions or failures to act that would (absent application of this
Section 4.13) constitute violations of this Section 4.13 solely as a result of
such amendment.

Section 4.14      Corporate Existence.

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

                  (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 shall 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)      If a Change of Control occurs, each holder of Notes shall have
the right to require the Company to repurchase all or any part (equal to $1,000
or an integral multiple of $1,000) of that holder's Notes pursuant to the offer
described below (the "Change of Control Offer") on the terms set forth in this
Indenture. In the Change of Control Offer, the Company shall offer a payment in
cash equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest, if any, on the Notes repurchased (the "Change of
Control Payment"), to but excluding the date of purchase. Within 30 days
following any Change of Control, the Company shall mail a notice to each holder
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase Notes on the change of control payment date (the
"Change of Control Payment Date") specified in the notice, which date shall be
no earlier than 30 days and no later than 60 days from the date such notice is
mailed, pursuant to the procedures required by this Indenture and described in
such notice. The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the Change of
Control provisions of this Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the Change of Control provisions of this
Indenture by virtue of such compliance.

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

                  (1)      accept for payment all Notes or portions of Notes
         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

                                       58



                  (3)      deliver or cause to be delivered to the trustee the
         Notes properly accepted together with an officers' certificate stating
         the aggregate principal amount of Notes or portions of Notes being
         purchased by the Company.

                  The paying agent shall promptly mail to each holder of Notes
properly tendered the Change of Control Payment for such Notes, and the Trustee
upon receipt of an Authentication Order from the Company shall 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 shall be in a principal amount
of $1,000 or an integral multiple of $1,000. The Company shall publicly announce
the results of the Change of Control Offer on or as soon as practicable after
the Change of Control Payment Date.

         (c)      The Company shall 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 Indenture applicable to a Change of Control Offer
made by the Company 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 herein, unless and until there is a default in payment
of the applicable redemption price.

Section 4.16      Limitation on Sale and Leaseback Transactions.

         (a)      The Company shall not enter into any sale and leaseback
transaction; provided that the Company may enter into a sale and leaseback
transaction if:

                  (1)      the Company could have (a) incurred Indebtedness in
         an amount equal to the Attributable Debt relating to such sale and
         leaseback transaction under the Fixed Charge Coverage Ratio test in
         Section 4.09 (a) herein and (b) incurred a Lien to secure such
         Indebtedness pursuant to Section 4.12 herein;

                  (2)      the gross cash proceeds of that sale and leaseback
         transaction are at least equal to the Fair Market Value, as determined
         in good faith by the Board of Directors and set forth in an officers'
         certificate delivered to the Trustee, of the property that is the
         subject of that sale and leaseback transaction; and

                  (3)      the transfer of assets in that sale and leaseback
         transaction is permitted by, and the Company applies the proceeds of
         such transaction in compliance with, Section 4.10 herein.

         (b)      This Section 4.16 shall not apply to the Company's
Subsidiaries.

Section 4.17      Limitation on Issuances of Guarantees of Indebtedness.

         The Company shall not permit any of its Restricted Subsidiaries,
directly or indirectly, to Guarantee or pledge any assets to secure the payment
of any other Indebtedness of the Company (other than the Existing Guarantees by
the Canadian Guarantors) unless such Restricted Subsidiary simultaneously
executes and delivers (1) supplemental indentures providing for the Guarantees
of the payment of the Notes by such Restricted Subsidiary, which Guarantees
shall be senior to such Restricted Subsidiary's Guarantee of or pledge to secure
such other Indebtedness unless the Indebtedness of the Company so Guaranteed or
secured is senior Indebtedness of the Company, in which case the Guarantees of
the Notes may be pari passu with such Restricted Subsidiary's Guarantee of or
pledge to secure such other Indebtedness of the Company, and (2) a pledge or
security agreement providing for a pledge of such

                                       59



assets to secure the Notes and all other Parity Lien Debt on an equal and
ratable basis (subject only to Permitted Prior Liens).

Section 4.18      Payments for Consent.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any holder of
the Notes the 2007 Notes, the 2010 Notes or the Term Loans for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture, the Notes, the 2007 Notes, the 2010 Notes, the Term Loans,
the Term Loan Agreement or any Security Documents unless such consideration is
offered to be paid or agreed to be paid to all holders of such notes and/or Term
Loans 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 4.19      Designation of Restricted and Unrestricted Subsidiaries.

         The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate
Fair Market Value of all outstanding Investments owned by the Company and its
Restricted Subsidiaries in the Subsidiary designated as Unrestricted shall be
deemed to be an Investment made as of the time of the designation and shall
reduce the remaining amount available for Restricted Payments under Section 4.07
herein or under one or more clauses of the definition of Permitted Investments,
as determined by the Company. That designation shall only be permitted if the
Investment would be permitted at that time and if the Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. The Board of
Directors may redesignate any Unrestricted Subsidiary to be a Restricted
Subsidiary if that redesignation would not cause a Default.

Section 4.20      Changes in Covenant When Notes Rated Investment Grade.

         If on any date following the date of this Indenture:

                  (1)      any series of the notes is 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 be continuing, then, beginning on that day and subject to the
         provisions of the following paragraph, the provisions of Section 4.07,
         4.08, 4.09, 4.10, 4.11, 4.13, 4.19 and clause (4) of Section 5.01
         hereof shall be suspended.

         Notwithstanding the foregoing, if the rating assigned by either such
rating agency should subsequently decline to below Baa3 or BBB-, respectively,
the foregoing provisions shall be reinstituted as of and from the date of such
rating decline. Calculations under the reinstated Section 4.07 shall be made as
if Section 4.07 had been in effect since the date of this Indenture except that
no default shall be deemed to have occurred solely by reason of a Restricted
Payment made while that Section 4.07 was suspended. These covenant suspension
provisions shall continue to be applicable following any such reinstatement. The
Company shall notify the Trustee if any covenants are suspended or reinstated
pursuant to this Section 4.20.

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
Restricted Subsidiaries taken as a whole, in one or more related transactions,
to another Person; unless:

                  (1)      either:

                           (A)      the Company is the surviving corporation; or

                           (B)      the Person formed by or surviving any such
                  consolidation or merger (if other than the Company) or to
                  which such sale, assignment, transfer, conveyance or other
                  disposition has been made is a corporation organized or
                  existing under the laws of the United States, any state of the
                  United States or the District of Columbia;

                  (2)      the Person formed by or surviving any such
         consolidation or merger (if other than the Company) or the Person to
         which such sale, assignment, transfer, conveyance or other disposition
         has been made assumes all the obligations of the Company under the
         Notes, this Indenture, and the Security Documents pursuant to

         Trustee;

                  (3)      immediately after such transaction, no Default or
         Event of Default exists;

         such consolidation or merger (if other than the Company), or to which
         such sale, assignment, transfer, conveyance or other disposition has

                           (A)      shall have Consolidated Net Worth
                  immediately after the transaction equal to or greater than the
                  Consolidated Net Worth of the Company immediately preceding
                  the transaction; and

                           (B)      will, on the date of such transaction after
                  giving pro forma effect thereto and any related financing
                  transactions as if the same had occurred at the beginning of
                  the applicable four-quarter period, be permitted to incur at
                  least $1.00 of additional Indebtedness pursuant to the Fixed
                  Charge Coverage Ratio test set forth in Section 4.09(a)
                  herein; and

                  (5)      such transaction shall not impair the ability of the
         Company or any of its Subsidiaries to conduct their respective
         businesses in a manner so as to maintain the exemption of the Company
         and its Subsidiaries from treatment as a public utility holding company
         under PUHCA or an electric utility or public utility under any federal,
         state or local law, unless such exemption is no longer material to the
         Company and its Restricted Subsidiaries taken as a whole or to the
         Person formed by or surviving any such consolidation or merger (if
         other then the Company) and its Restricted Subsidiaries taken as a
         whole.

         In addition, the Company may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person.

                                       61



         Notwithstanding the foregoing:

                  (1)      the Company may merge with an Affiliate solely for
         the purpose of reincorporating the Company in another jurisdiction; and

                  (2)      the Company and its Restricted Subsidiaries may sell,

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 in a transaction that is subject to, and that complies with the
provisions of, Section 5.01 hereof, 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 hereof.

Section 6.01      Events of Default.

         Each of the following is an "Event of Default":

                  (1)      default for 30 days in the payment when due of
         interest on the Notes;

                  (2)      default in payment when due of the principal of, or
         premium, if any, on the Notes;

         that series of notes to comply with any of the other agreements in this
         Indenture, the Notes or the Security Documents;

                  (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 Restricted Subsidiaries (or the payment of which is guaranteed by
         the Company or any of its Restricted Subsidiaries) whether such
         Indebtedness or guarantee now exists, or is created after the date of
         this Indenture, if that default:

                                       62



                           (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 $50.0 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 such Restricted Subsidiary becoming
aware of such default; provided that the provisions of this clause (5) shall not
apply to any default on Non-Recourse Debt;

         Subsidiaries to pay final judgments (not covered by insurance)

         discharged or stayed for a period of 30 days;

                  (7)      the repudiation by the Company or any of its

         Documents or the unenforceability of the Security Documents against the
         Company or any of its Restricted Subsidiaries for any reason; provided
         that such breach, repudiation or unenforceability relates to Collateral
         having an aggregate Fair Market Value of $50.0 million or more;

                  (8)      except as permitted by this Indenture, any note
         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 Canadian Guarantor, or any Person acting on behalf of any
         Canadian Guarantor, shall deny or disaffirm its obligations under its
         note Guarantee and such condition shall not have been cured within 30
         days of written notice from the Trustee or the holders of at least 25%
         in outstanding aggregate principal amount of the Notes; and

                  (9)      the Company or any of its Significant Subsidiaries or
         any group of Subsidiaries that, taken as a whole, 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; and

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

                                       63



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

                           (B)      appoints a custodian of the Company or any
                  of its Significant Subsidiaries or any group of Subsidiaries
                  that, taken as a whole, would constitute a Significant
                  Subsidiary or for all or substantially all of the property of
                  the Company or any of its Significant Subsidiaries or any
                  group of Subsidiaries that, taken as a whole, would constitute
                  a Significant Subsidiary; or

                           (C)      orders the liquidation of the Company or any
                  of its Significant Subsidiaries or any group of Subsidiaries
                  that, taken as a whole, 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 (9) or (10) of
Section 6.01 hereof, with respect to the Company or any of its Significant
Subsidiaries or any group of Subsidiaries that, taken as a whole, would
constitute a Significant Subsidiary, all outstanding Notes shall 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
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. Notwithstanding the foregoing, if an Event of Default specified in
clause (9) of Section 6.01 hereof occurs with respect to the Company, any of its
Significant Subsidiaries or any group of Subsidiaries that, taken as a whole,
would constitute a Significant Subsidiary, all outstanding Notes shall be due
and payable immediately without further action or notice. 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 that has become due solely because of the
acceleration) have been cured or waived.

         If an Event of Default occurs on or after July 15, 2008 by reason of
any willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding payment of the premium that the Company
would have had to pay if the Company then had elected to redeem the Notes
pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an
equivalent premium shall also become and be immediately due and payable, to the
extent permitted by law, anything in this Indenture or in the Notes to the
contrary notwithstanding. If an Event of Default occurs prior to July 15, 2008
by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, upon acceleration of the
Notes, an additional premium shall also become and be immediately due and
payable in an amount, for each of the years beginning on July 15 of the years
set forth below, as set forth below (expressed as a percentage of the principal
amount of the Notes on the date of payment that would otherwise be due but for
the provisions of this sentence):

         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 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 not less than a majority in aggregate principal amount of
the then outstanding Notes by 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, if any, or interest on, the Notes
(including in connection with an offer to purchase); provided, however, that the
Holders of a majority in aggregate principal amount of the then outstanding
Notes may rescind an acceleration and its consequences, including any related
payment default that resulted from such acceleration. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

Section 6.05      Control by Majority.

         Holders of a majority in principal amount 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.

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

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

                  (2)      the Holders of at least 25% in principal amount of
         the then outstanding Notes make a written request to the Trustee to
         pursue the remedy;

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

                                       65



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

                  (5)      during such 60-day period the Holders of a majority
         in principal amount of the then outstanding Notes do not give the
         Trustee a direction inconsistent with the request.

         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, 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 continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount of
principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

Section 6.09      Trustee May File Proofs of Claim.

         The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the 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
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the 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.

                                       66



Section 6.10      Priorities.

         If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

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

                  Second: to Holders of Notes for amounts due and unpaid on the
         Notes for principal, premium, 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, if any and interest,
         respectively; and

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

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

Section 6.11      Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any 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 hereof, or a suit by Holders of more than 10% in
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 shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent 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 shall 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.

                                       67



         However, the Trustee shall 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
         mathematical 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:

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

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

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

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

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

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

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

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

                                       68



         (f)      The Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction
of 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, except for
Events of Default specified in Section 6.01(1) and/or 6.01(2) hereof, unless and
until the Trustee shall have received from a Holder of a Note or from the
Company express written notice of the circumstances constituting the breach,
default or Event of Default and stating that said circumstances constitute an
Event 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 ascertaining it
has 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
hereof.

Section 7.04      Trustee's Disclaimer.

         The Trustee shall 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 shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital 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 shall 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, 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 date of this Indenture, and for so long as Notes remain
outstanding, the Trustee shall 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

                                       69



transmitted). The Trustee also shall comply with TIA Section 313(b)(2) to the
extent applicable. The Trustee shall 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 shall 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 shall promptly notify the
Trustee when the Notes are listed on any stock exchange.

Section 7.07      Compensation and Indemnity.

         (a)      The Company shall pay to the Trustee from time to time
reasonable compensation for its acceptance of this Indenture and services
hereunder. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the
Trustee 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 shall include the reasonable compensation, disbursements
and expenses of the Trustee's agents and counsel.

         (b)      The Company shall 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,
including the costs and expenses of enforcing this Indenture (and any other Note
Documents to which it is a party) against the Company (including this Section
7.07) and defending itself against any claim (whether asserted by the Company,
or any Holder or any other Person) or liability 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. The Trustee shall notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the
claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel. The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld.

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

         (d)      To secure the Company's payment obligations in this Section
7.07, the Trustee shall 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 and
interest on particular Notes. Such Lien shall 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(9) or (10) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses
of its agents and counsel) are intended to constitute expenses of administration
under any Bankruptcy Law.

Section 7.08      Replacement of Trustee.

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

         (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 principal amount of the then

                                       70



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 hereof;

                  (2)      the Trustee is adjudged a bankrupt or an insolvent or

         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 shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in principal amount of the then outstanding 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 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 shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, provided all sums owing to the
Trustee hereunder have been paid and subject to the Lien provided for in Section
7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

Section 7.09      Successor Trustee by Merger, etc.

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

Section 7.10      Eligibility; Disqualification.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition.

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

                  (1)      the rights of Holders of outstanding Notes to receive

shall 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 shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Company's exercise under Section
8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(3) through 6.01(5) hereof shall 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 hereof:

                  (1)      the Company 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 shall be sufficient, in the opinion of a
         nationally recognized investment bank, appraisal firm or firm of
         independent public accountants, to pay the principal of, premium, if
         any, and interest on the outstanding Notes on the stated date for
         payment thereof or on the applicable redemption date, as the case may
         be, and the Company must specify whether such Notes are being defeased
         to maturity or to a particular redemption date;

                  (2)      in the case of an election under Section 8.02 hereof,
         the Company has delivered to the Trustee an Opinion of Counsel in the
         United States reasonably acceptable to the Trustee confirming that:

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

                           (B)      since the date of this Indenture, 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 shall not recognize income, gain or loss for
                  federal income tax purposes as a result of such Legal
                  Defeasance and shall 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 hereof,
         the Company must deliver to the Trustee an Opinion of Counsel in the
         United States reasonably acceptable to the Trustee confirming that the
         Holders of the outstanding Notes shall not recognize income, gain or
         loss for federal income tax purposes as a result of such Covenant
         Defeasance and shall 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;

                                       73



                  (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 shall
         not result in a breach or violation of, or constitute a default under,
         any material agreement or instrument (other than this Indenture) to
         which the Company or any of its Subsidiaries is a party or by which the
         Company or any of its Subsidiaries is bound;

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

                  (7)      the Company must deliver to the Trustee an Officers'
         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 hereof, 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 hereof in respect of the outstanding Notes
shall 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, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

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

         Notwithstanding anything in this Article 8 to the contrary, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized
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) hereof), are in excess of the
amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06      Repayment to the Company.

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

                                       74



and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
shall be repaid to the Company.

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 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01      Without Consent of Holders of Notes.

         Notwithstanding Section 9.02 of this Indenture, the Company and the
Trustee may amend or supplement this Indenture or the Notes without the consent
of any Holder of a Note:

                  (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 Company's
         obligations to the Holders of the Notes by a successor to the Company
         pursuant to Article 5 hereof;

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

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

                  (6)      to provide for the issuance of Additional Notes in
         accordance with the limitations set forth in this Indenture as of the
         date hereof;

                  (7)      to allow any Guarantor to execute a supplemental
         indenture and/or a Guarantee with respect to the Notes;

                  (8)      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;

                                       75



                  (9)      to conform the text of this Indenture, the Notes or
         the Security Documents to any provision of the Description of the Notes
         section of the Offering Circular to the extent that such provision of
         the Description of the Notes section of the Offering Circular was
         intended to be a verbatim recitation of a provision of this Indenture,
         the Notes or the Security Documents; or

                  (10)     to reflect any waiver or termination of any right
         arising under the provisions of this Indenture that otherwise would be
         enforceable by any holder of the Term Loan Obligations, if such waiver
         or termination is set forth in the agreement governing such Term Loan
         Obligations, provided that no such waiver or amendment shall adversely
         affect the right of holders of 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 hereof, the Trustee shall join with the Company in the execution of any
amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

Section 9.02      With Consent of Holders of 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 hereof), the Guarantees and the Notes with the
consent of the Holders of at least a majority in principal amount of the Notes
(including, without limitation, Additional Notes, if any) 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 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, 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 Guarantees or the Notes may be waived
with the consent of the Holders of a majority in 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).

         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 hereof, the Trustee shall
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 shall not be obligated to, enter into
such amended or supplemental Indenture.

         It is 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 shall 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, shall not,
however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount

                                       76



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 or waive any of the provisions with respect to the
         redemption of the Notes except as provided above with respect to
         Sections 3.09, 4.10 and 4.15 hereof;

                  (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 interest or premium, 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 past Defaults or the rights of Holders of Notes
         to receive payments of principal of, or interest or premium, if any, on
         the Notes;

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

                  (8)      release (A) any Collateral from the Liens created by
         the Security Documents except as specifically provided in this
         Indenture and the Security Documents as of the date of this Indenture
         or (B) all or substantially all of the Collateral or all or
         substantially all of the Canadian Guarantors from their obligations
         under the Guarantee and Collateral Agreement dated July 16, 2003
         without the prior written consent of all Holders; or

                  (9)      make any change in Section 6.04 or 6.07 hereof or in
         the foregoing amendment and waiver provisions.

Section 9.03      Compliance with Trust Indenture Act.

         Every amendment or supplement to this Indenture or the Notes shall be
set forth in a 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,

                                       77



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 shall not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06      Trustee to Sign Amendments, etc.

         The Trustee shall 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
shall be entitled to receive and (subject to Section 7.01 and 7.02 hereof) shall
be fully protected in relying upon, in addition to the documents required by
Section 13.04 hereof, an Officers' Certificate and an Opinion of Counsel stating
that the execution of such amended or supplemental Indenture is authorized or
permitted by this Indenture.

Lien Debt; Sharing Confirmation.

         Notwithstanding (1) anything to the contrary contained in the Security
Documents, (2) the time of incurrence of any Series of Parity Lien Debt, (3) the
order or method of attachment or perfection of any Liens securing any Series of
Parity Lien Debt, (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 other Obligor to secure any of the Parity Lien Debt
                  shall secure, equally and ratably, all present and future
                  Parity Lien Obligations; and

                           (B)      all proceeds of all Liens at any time
                  granted by the Company or any Obligor to secure any of the
                  Parity Lien Debt and other Parity Lien Obligations shall be
                  allocated and distributed equally and ratably on account of
                  the Parity Lien Debt and other Parity Lien Obligations;
                  provided, that, for the avoidance of doubt, in the absence of
                  an Event of Default, the Company shall be entitled to utilize
                  cash proceeds of Collateral in the ordinary course of its
                  business.

         The foregoing provision is intended for the benefit of, and shall be
enforceable as a third party beneficiary by, each present and future holder of
Parity Lien Obligations, each present and future Parity Debt Representative and
the Collateral Trustee as holder of Parity Liens. The Company shall not incur

                                       78



any future Series of Parity Lien Debt unless the agreement governing such Series
of Parity Lien Debt includes a Sharing Confirmation at the time of incurrence of
such Series of Parity Lien Debt.

Section 10.02     Ranking of Note Liens

         Notwithstanding:

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

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

                  (3)      the order or method of attachment or perfection of

         Collateral or

                  (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 other Obligor to secure any
of the Parity Lien Debt shall be subject and subordinate to Priority Liens
securing Priority Lien Obligations up to the Priority Lien Cap.

         The foregoing provision is intended for the benefit of, and shall be
enforceable as a third party beneficiary by, each present and future holder of
Priority Lien Obligations, each present and future Priority Lien Agent and the
Collateral Trustee as holder of Priority Liens. No other Person shall be
entitled to rely on, have the benefit of or enforce this provision.

         In addition, the foregoing provision is intended solely to set forth
the relative ranking, as Liens, of the Liens securing Parity Lien Debt as
against the Priority Liens. Neither the Notes, the 2007 Notes, the 2010 Notes
nor the Term Loans nor any other Parity Lien Obligations nor the exercise or
enforcement of any right or remedy for the payment or collection thereof are
intended to be, or shall ever by reason of the foregoing provision, in any
respect subordinated, deferred, postponed, restricted or prejudiced.

         The Collateral Trustee's Liens upon the Collateral shall no longer
secure the Notes or any other Obligations under this Indenture, and the right of
the holders of the Notes and Obligations to the benefits and proceeds of the

                  (1)      upon satisfaction and discharge of this Indenture in
         accordance with Article 11 hereof;

                  (2)      upon a Legal Defeasance or Covenant Defeasance of the

         outstanding under this Indenture and all related Obligations that are
         outstanding, due and payable under this Indenture at the time the Notes
         are paid in full and discharged.

effect as to all Notes issued hereunder, when:

                  (1)      either:

                           (a)      all Notes that have been authenticated under
         this Indenture (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 Company) 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 making of a notice of redemption or otherwise or shall become due
         and payable within one year and the Company 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 shall 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, 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 shall occur as a result of
         such deposit and such deposit shall not result in a breach or violation
         of, or constitute a default under, any other instrument to which the
         Company is a party or by which the Company is bound;

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

                  (4)      the Company has 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 Company must deliver an Officers' 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, the provisions of Section 12.02 and Section 8.06 shall
survive. In addition, nothing in this Section 11.01 shall be deemed to discharge
those provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

Section 11.02     Application of Trust Money.

         Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 11.01 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 the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium, 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 11.01 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 obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 11.01; provided
that if the Company has made any payment of principal of, premium, if any, or
interest on any Notes because of the reinstatement of its obligations, the
Company 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.

                  (1)      INTEREST. Calpine Corporation, a Delaware corporation
         (the "Company"), promises to pay interest on the principal amount of
         this Note at 8.75% per annum from July 16, 2003 until maturity. The
         Company shall pay interest semi-annually in arrears on January 15 and
         July 15 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 shall 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
         shall be January 15, 2004. The Company shall 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; it
         shall pay interest (including post-petition interest in any proceeding
         under any Bankruptcy Law) on overdue installments of interest (without
         regard to any applicable grace periods) from time to time on demand at
         the same rate to the extent lawful. Interest shall be computed on the
         basis of a 360-day year of twelve 30-day months.

                  (2)      METHOD OF PAYMENT. The Company shall pay interest on
         the Notes (except defaulted interest) to the Persons who are registered
         Holders of Notes at the close of business on the January 1 or July 1
         next 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 shall be payable as to principal,
         premium, if any, and interest 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 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 shall be required with respect to principal
         of and interest, premium on, all Global Notes and all other Notes the
         Holders of which shall have provided wire transfer instructions to the
         Company or the Paying Agent. Such payment shall 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. Initially, Wilmington
         Trust Company, the Trustee under the Indenture, shall act as Paying
         Agent and Registrar. The Company may change any Paying Agent or
         Registrar without prior notice to any Holder. The Company or any of its
         Subsidiaries may act in any such capacity.

                  (4)      INDENTURE. The Company issued the Notes under an
         Indenture dated as of July 16, 2003 (the "Indenture") between the
         Company 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, as evidenced by the Security Documents referred to in the
         Indenture.

         the Company shall have the option to redeem the Notes, in whole or in
         part, upon not less than 30 nor more than 60 days' notice, at the

         offer described below (the "Change of Control Offer") on the terms set
         forth in the Indenture. In the Change of Control Offer, the Company
         shall offer a payment in cash equal to 101% of the aggregate principal
         amount of Notes repurchased plus accrued and unpaid interest, if any,

         Control, the Company shall mail a notice to each holder as required by
         the Indenture. (b) If the Company or a Subsidiary consummates any Asset
         Sales, and when the aggregate amount of Excess Proceeds exceeds $50.0
         million, or at such earlier point as may be elected by the Company, the
         Company shall make an offer to all holders of Notes and all holders of
         other Indebtedness that is pari passu with the Notes and equally and
         ratably secured with the Notes containing provisions similar to those
         set forth in the Indenture with respect to offers to purchase or redeem
         with the proceeds of sales of assets, including the Term Loans and each
         series of Existing Indebtedness that contains similar asset sale
         provisions, when applicable (an "Asset Sale Offer"), to purchase or
         redeem the maximum principal amount of Notes and such other pari passu
         Indebtedness that may be purchased or redeemed out of the Excess
         Proceeds (including each series of Existing Indebtedness that contains
         similar asset sale provisions). The offer price in any Asset Sale Offer
         shall be equal to 100% of principal amount plus accrued and unpaid
         interest, if any, to the date of purchase, and shall be payable in
         cash. If any Excess Proceeds remain after consummation of an Asset Sale
         Offer, the Company may use those Excess

                                       A-4



         Proceeds for any purpose not otherwise prohibited by the Indenture.
         If the aggregate principal amount of Notes and other pari passu
         Indebtedness tendered into such Asset Sale Offer exceeds the amount of
         Excess Proceeds, the Company shall select the Notes and such other pari
         passu Indebtedness to be purchased on a pro rata basis. Upon completion
         of each Asset Sale Offer, the amount of Excess Proceeds shall be reset
         at zero. Holders of Notes that are the subject of an offer to purchase
         shall receive an Asset Sale Offer from the Company prior to any related
         purchase date and may elect to have such Notes purchased by completing
         the form entitled "Option of Holder to Elect Purchase" on the reverse
         of the Notes.

                  (8)      NOTICE OF REDEMPTION. Notice of redemption shall 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 of $1,000. 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.

                  (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, the Indenture or the Notes may be amended or supplemented
         with the consent of the Holders of at least a majority in principal
         amount of the then outstanding Notes and Additional Notes, if any,
         voting as a single class, and any existing default or compliance with
         any provision of the Indenture or the Notes may be waived with the
         consent of the Holders of a majority in principal amount of the then
         outstanding Notes and Additional Notes, if any, voting as a single
         class. Without the consent of any Holder of a Note, the Indenture, the
         Guarantees or the Notes may be amended or supplemented to cure any
         ambiguity, defect or inconsistency, to provide for uncertificated Notes
         in addition to or in place of certificated Notes, to provide for the
         assumption of the Company's obligations to Holders of the Notes in case
         of a merger or consolidation, to make any change that would provide any
         additional rights or benefits to 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 provide for the issuance of Additional Notes in
         accordance with the limitations set forth in the Indenture, to allow
         any Guarantor to execute a supplemental indenture to the Indenture
         and/or a Guarantee with respect to the Notes, 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 or any of the Security
         Documents, to conform the text of the Indenture, the Notes or the
         Security Documents to any provision of the Description of the Notes
         section of the Offering

                                       A-5



         Circular to the extent that such provision of the Description of the
         Notes section of the Offering Circular was intended to be a verbatim
         recitation of a provision of the Indenture, the Notes or the Security
         Documents, or to reflect any waiver or termination of any right arising
         under the provisions of the Indenture that otherwise would be
         enforceable by any holder of the Term Loan Obligations, if such waiver
         or termination is set forth in the agreement governing such Term Loan
         Obligations, provided that no such waiver or amendment shall adversely
         affect the right of holders of Notes.

                  (12)     DEFAULTS AND REMEDIES. Events of Default include:
         (i) default for 30 days in the payment when due of interest on the
         Notes; (ii) default in payment when due of principal of or premium, if
         any, on the Notes, (iii) failure by the Company to purchase the Notes
         when required pursuant to Section 4.10 or 4.15 of the Indenture or
         otherwise as required pursuant to the Indenture or Notes; (iv) failure
         by the Company or any of its Restricted Subsidiaries for 30 days after
         written notice from the Trustee or the holders of at least 25% in
         outstanding aggregate principal amount of the Notes to comply with any
         of the other agreements in the Indenture, the Notes or the Security
         Documents; (v) default under certain other agreements relating to
         Indebtedness of the Company which default results in the acceleration
         of such Indebtedness prior to its express maturity; (vi) certain final
         judgments for the payment of money that remain undischarged for a
         period of 30 days; (vii) certain events of bankruptcy or insolvency
         with respect to the Company or any of its Restricted Subsidiaries that
         would constitute a Significant Subsidiary or any group of Restricted
         Subsidiaries that, taken together, would constitute a Significant
         Subsidiary; (viii) the repudiation by the Company or any of its
         Restricted Subsidiaries or the unenforceability of the Security
         Documents if such breach, repudiation or unenforceability relates to
         Collateral having an aggregate Fair Market Value of $50.0 million or
         more and (ix) except as permitted by the Indenture, any 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 Guarantee. If any Event of
         Default occurs and is continuing, the Trustee or the Holders of at
         least 25% in 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 shall become due and
         payable without further action or notice. Holders may not enforce the
         Indenture or the Notes except as provided in the Indenture. 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 if it determines
         that withholding Notes is in their interest, except a Default or Event
         of Default relating to the payment of principal or 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 interest on, or the principal of, the
         Notes. The Company is required to deliver to the Trustee annually a
         statement regarding compliance with the Indenture, and the Company is
         required upon becoming aware of any Default or Event of Default under
         clauses (3) through (8) of the Section 6.01(a) of the Indenture, 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.

         employee, incorporator or stockholder, of the Company as such, shall
         not have any liability for any obligations of the Company under the
         Notes, 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. The waiver and release
         are part of the consideration for the issuance of the Notes.

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

         promulgated by the Committee on Uniform Security Identification
         Procedures, the Company has caused CUSIP numbers to be printed on the

         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.
