managers cannot resolve the dispute or either of them determines they
are not making progress toward the resolution of the dispute within
three (3) business days after their initial conference, then the dispute
may be submitted to a vice-president designed by each Party, who shall
promptly confer to resolve the dispute. If the vice-president designees

re-name such product and thereafter Dagger’s name or mark shall be
prominently displayed and associated with such product. In
connection

 

 

	 	 	with a reasonably implemented transition to a new product
name or mark and thereafter whenever an historic naming reference is
appropriate or required, Dagger may refer to the prior product name,
provided that all such references shall be accurate and
appropriately displayed and sized.

10. CONFIDENTIAL INFORMATION

	10.1.	 	“Confidential Information” shall include any information disclosed
by one Party (“Discloser”) to the other Party (“Recipient”), and marked
“confidential,” including source code, specifications, business and/or
technical information relating to the business of Arrow or Dagger.
	 
	10.2.	 	All Confidential Information disclosed prior to, at or in connection
with the Closing shall be subject to the APA. All Confidential
Information disclosed after and not in connection with the Closing shall
remain the property of Discloser, except as provided in this Agreement.
Recipient’s duty to protect Confidential Information commences upon
receipt of the Confidential Information. Recipient shall copy
Confidential Information only to the extent necessary to exercise its
rights and obligations under this Agreement. Copies of Confidential
Information shall include any proprietary and copyright notices in the
Confidential Information.
	 
	10.3.	 	Recipient shall restrict disclosure of Confidential Information to
its employees with a need to know and advise such employees of the
obligations assumed herein, and Recipient shall not disclose
Confidential Information to any third party without prior written
approval of Discloser. All Confidential Information that is disclosed
for the purpose(s) set forth in this Agreement shall be subject to these
restrictions and may not be used for any other purpose. The fact that a
discussion involving the disclosure of Confidential Information will
occur or has occurred shall be considered Confidential Information.
	 
	10.4.	 	These restrictions on the use and disclosure of Confidential
Information shall not apply to any Confidential Information:

	10.4.1.	 	independently developed by Recipient or lawfully received free of
restriction from another source having the right to furnish the
Confidential Information; or
	 
	10.4.2.	 	after it has become generally available to or known by the public
without breach of this Agreement by Recipient; or
	 
	10.4.3.	 	that, at the time of disclosure to Recipient, was known to
Recipient free of restriction as evidenced by documentation in
Recipient’s possession.

	10.5.	 	The Parties agree that in the case of the breach of any provision of
the section of this Agreement entitled Confidentiality, the aggrieved
party may suffer immediate and irreparable harm, and that immediate
injunctive relief may therefore be appropriate.

 

 

11. BREACH; REMEDIES

	11.1.	 	This Agreement and the licenses set forth herein may be terminated
only by mutual agreement of the Parties documented in a written
agreement executed and delivered by the authorized representatives of
Arrow and Dagger.
	 
	11.2.	 	In the event of a breach of this Agreement by a Party, the
non-breaching Party shall be entitled to recover full money damages,
including, without limitation, any and all costs, losses, claims,
liabilities, fines, penalties, damages and expenses, court costs, and
reasonable fees and disbursements of counsel, consultants and expert
witnesses incurred by a Party hereto (including any interest payments
which may be imposed in connection therewith) consequential damages,
lost profits (“Damages”) incurred as a result of such breach and its
consequential enforcement of this Agreement. Each Grantee with respect
to a license hereunder agrees to indemnify, defend and hold harmless the
Grantor, and its officers, directors, employees, agents, Affiliates,

connection with, or based on allegations of any failure to perform duly
and punctually any covenant, agreement or undertaking on the part of
Grantee contained in this Agreement.

not contest the validity of any of the Technology or intellectual
property transferred, assigned or licensed hereunder.
	 
	11.4.	 	Specific Performance. The Parties hereto acknowledge that damages
alone may not adequately compensate a Licensor for violation by the
Licensee of this Agreement. Accordingly, in addition to all other
remedies that may be available hereunder or under applicable law,
Licensor shall have the right to any equitable relief that may be
appropriate to remedy a breach or threatened breach by Licensee
hereunder, including the right to enforce specifically the terms of this
Agreement by obtaining injunctive relief in respect of any violation or
non-performance hereof, without posting bond.

12. CONDITIONS PRECEDENT AND REPRESENTATIONS.

Arrow or, to the Knowledge of Arrow, against any of Arrow’s
customers or licensees, any written claims of intellectual property
in the Technology or written claims of intellectual property
infringement arising out of or related to use of the Technology in
the Business. To the Knowledge of Arrow, no claims are threatened

                                   THE NOTES

Section 2.01 Form and Dating.

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

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

controlling.

         (b)      Global Notes. Notes issued in global form will be
substantially in the form of Exhibit A attached hereto (including the Global
Note Legend thereon and the "Schedule of Exchanges of Interests in the Global

attached thereto). Each Global Note will represent such of the outstanding Notes
as will be specified therein and each shall provide that it represents the
aggregate principal amount of outstanding Notes from time to time endorsed
thereon and that the aggregate principal amount of outstanding Notes represented

Custodian, at the direction of the Trustee, in accordance with instructions
given by the Holder thereof as required by Section 2.06 hereof.

         (c)      Euroclear and Clearstream Procedures Applicable. The

held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

         At least one Officer must sign the Notes for the Company by manual or
facsimile signature.

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

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

                                       37
<PAGE>

         The Trustee will, upon receipt of a written order of the Company signed
by an Officer (an "Authentication Order"), authenticate Notes for (i) original
issue up to the aggregate principal amount stated in paragraph 4 of the Notes
and (ii) Additional Notes in such amounts as may be specified from time to time
without limit, subject to Article 4 hereof.

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

Section 2.03 Registrar and Paying Agent.

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

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

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

Section 2.05 Holder Lists.

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

Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global Notes
will be exchanged by the Company for Definitive Notes if:

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

                  (2) the Company in its sole discretion determines that the

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 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

this Indenture and the Applicable Procedures. Beneficial interests in the

         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). Beneficial interests
         in any Unrestricted Global Note may be transferred to Persons who take
         delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Note. No written orders or instructions shall be
         required to be delivered to the Registrar to effect the transfers
         described in this Section 2.06(b)(1).

                  (2) All Other Transfers and Exchanges of Beneficial Interests

                           (D)      the Registrar receives the following:

                                    (i)      if the Holder of such Definitive
                           Notes proposes to exchange such Notes for a
                           beneficial interest in the Unrestricted Global Note,
                           a certificate from such Holder in the form of Exhibit
                           C hereto, including the certifications in item (1)(c)
                           thereof; or

                                    (ii)     if the Holder of such Definitive
                           Notes proposes to transfer such Notes to a Person who
                           shall take delivery thereof in the form of a
                           beneficial interest in the Unrestricted Global Note,
                           a certificate from such Holder in the form of Exhibit
                           B hereto, including the certifications in item (4)
                           thereof;

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

                  Upon satisfaction of the conditions of any of the
         subparagraphs in this Section 2.06(d)(2), the Trustee will cancel the
         Definitive Notes and increase or cause to be increased the aggregate
         principal amount of the Unrestricted Global Note.

                  (3) Unrestricted Definitive Notes to Beneficial Interests in
         Unrestricted Global Notes. A Holder of an Unrestricted Definitive Note
         may exchange such Note for a beneficial interest in an Unrestricted
         Global Note or transfer such Unrestricted Definitive Notes to a Person
         who takes delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Note at any time. Upon receipt of a request for
         such an exchange or transfer, the Trustee will cancel the applicable
         Unrestricted Definitive Note and increase or cause to be increased the
         aggregate principal amount of one of the Unrestricted Global Notes.

                  If any such exchange or transfer from a Definitive Note to a
         beneficial interest is effected pursuant to subparagraphs (2)(B),
         (2)(D) or (3) above at a time when an Unrestricted Global Note has not
         yet been issued, the Company will issue and, upon receipt of an
         Authentication Order in accordance with Section 2.02 hereof, the
         Trustee will authenticate one or more Unrestricted

                                       45

         Global Notes in an aggregate principal amount equal to the principal
         amount of Unrestricted Definitive Notes so transferred.

         (e)      Transfer and Exchange of Definitive Notes for Definitive
Notes. Upon request by a Holder of Definitive Notes and such Holder's compliance
with the provisions of this Section 2.06(e), the Registrar will register the
transfer or exchange of Definitive Notes. Prior to such registration of transfer
or exchange, the requesting Holder must present or surrender to the Registrar
the Definitive Notes duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Registrar duly executed by such Holder or

         following:

                           (A)      if the transfer will be made pursuant to
                  Rule 144A, then the transferor must deliver a certificate in
                  the form of Exhibit B hereto, including the certifications in
                  item (1) thereof;

                           (B)      if the transfer will be made pursuant to
                  Rule 903 or Rule 904, then the transferor must deliver a
                  certificate in the form of Exhibit B hereto, including the
                  certifications in item (2) thereof; and

                           (C)      if the transfer will be made pursuant to any
                  other exemption from the registration requirements of the
                  Securities Act, then the transferor must deliver a certificate
                  in the form of Exhibit B hereto, including the certifications,
                  certificates and Opinion of Counsel required by item (3)
                  thereof, if applicable.

                  (2) Restricted Definitive Notes to Unrestricted Definitive
         Notes. Any Restricted Definitive Note may be exchanged by the Holder
         thereof for an Unrestricted Definitive Note or transferred to a Person
         or Persons who take delivery thereof in the form of an Unrestricted
         Definitive Note if:

                           (A)      such exchange or transfer is effected
                  pursuant to the Exchange Offer in accordance with the
                  Registration Rights Agreement and the Holder, in the case of
                  an exchange, or the transferee, in the case of a transfer,
                  certifies in the applicable Letter of Transmittal that it is
                  not (i) a broker-dealer, (ii) a Person participating in the
                  distribution of the Exchange Notes or (iii) a Person who is an
                  affiliate (as defined in Rule 144) of the Company;

                           (B)      any such transfer is effected pursuant to
                  the Shelf Registration Statement in accordance with the
                  Registration Rights Agreement;

                           (C)      any such transfer is effected by a
                  Broker-Dealer pursuant to the Exchange Offer Registration
                  Statement in accordance with the Registration Rights
                  Agreement; or

                           (D)      the Registrar receives the following:

                                       46
<PAGE>

                                    (i)      if the Holder of such Restricted
                           Definitive Notes proposes to exchange such Notes for
                           an Unrestricted Definitive Note, a certificate from
                           such Holder in the form of Exhibit C hereto,
                           including the certifications in item (1)(d) thereof;
                           or

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

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

                  (3) Unrestricted Definitive Notes to Unrestricted Definitive
         Notes. A Holder of Unrestricted Definitive Notes may transfer such
         Notes to a Person who takes delivery thereof in the form of an
         Unrestricted Definitive Note. Upon receipt of a request to register
         such a transfer, the Registrar shall register the Unrestricted
         Definitive Notes pursuant to the instructions from the Holder thereof.

         (f)      Exchange Offer. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Company will issue and,
upon receipt of an Authentication Order in accordance with Section 2.02 hereof,
the Trustee will authenticate:

                  (1)      one or more Unrestricted Global Notes in an aggregate
         principal amount equal to the principal amount of the beneficial
         interests in the Restricted Global Notes accepted for exchange in the
         Exchange Offer by Persons that certify in the applicable Letters of
         Transmittal that (A) they are not Broker-Dealers, (B) they are not
         participating in a distribution of the Exchange Notes and (C) they are

         principal amount equal to the principal amount of the Restricted
         Definitive Notes accepted for exchange in the Exchange Offer.

         Concurrently with the issuance of such Notes, the Trustee will cause
the aggregate principal amount of the applicable Restricted Global Notes to be
reduced accordingly, and the Company will execute and the Trustee will
authenticate and deliver to the Persons designated by the Holders of Definitive
Notes so accepted Unrestricted Definitive Notes in the appropriate principal
amount.

         (g)      Legends. The following legends will appear on the face of all
Global Notes and Definitive Notes issued under this Indenture unless
specifically stated otherwise in the applicable provisions of this Indenture.

                  (1) Private Placement Legend.

                           (A)      Except as permitted by subparagraph (B)

                  Definitive Note (and all Notes issued in exchange therefor or
                  substitution thereof) shall bear the legend in substantially
                  the following form:

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

         (i)      General Provisions Relating to Transfers and Exchanges.

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

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

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

                  (4) All Global Notes and Definitive Notes issued upon any
         registration of transfer or exchange of Global Notes or Definitive
         Notes will be the valid obligations of the 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) Neither the Registrar nor the Company will 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

                                       49
<PAGE>

         as the absolute owner of such Note for the purpose of receiving payment
         of principal, premium or Liquidated Damages, if any, or 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 will 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.

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 will issue and the Trustee, upon receipt of an
Authentication Order, will authenticate a replacement Note if the Trustee's
requirements 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 for its expenses in replacing a Note.

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

Section 2.08 Outstanding Notes.

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

         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 will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.09 Treasury Notes.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company or any Guarantor, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
Guarantor, will be considered as though not outstanding, except that for the
purposes of

                                       50
<PAGE>

determining whether the Trustee will be protected in relying on any such
direction, waiver or consent, only Notes that a Responsible Officer of the
Trustee knows are so owned will 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,
will authenticate temporary Notes. Temporary Notes will 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 will prepare and the Trustee
will authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11 Cancellation.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent will forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else will cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and will destroy
canceled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes will be delivered
to the 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 will
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Company will notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company will fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
may be less than 2 Business Days prior to the related payment date for such
defaulted interest. At least 5 Business Days before the special record date, the
Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) will mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid.

         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 (or such shorter period as agreed to by the Trustee) 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;

<PAGE>

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

                  (4) the redemption price.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

         If less than all of the Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee will select Notes for redemption or
purchase 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 other method as the
         Trustee shall deem fair and appropriate.

         In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased will be selected, unless otherwise provided
herein, not less than 25 nor more than 60 days prior to the redemption or
purchase date by the Trustee from the outstanding Notes not previously called
for redemption or purchase.

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

Section 3.03 Notice of Redemption.

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

         The notice will identify the Notes to be redeemed and will 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 will be issued upon
         cancellation of the original Note;

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

                                       52
<PAGE>

                  (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 will give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company has delivered to the Trustee, at least 35 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.

         One Business Day prior to the redemption or purchase date, the Company
will deposit with the Trustee or with the Paying Agent money sufficient to pay
the redemption or purchase price of and accrued interest and Liquidated Damages,
if any, on all Notes to be redeemed or purchased on that date. The Trustee or
the Paying Agent will 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 and
Liquidated Damages, if any, 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 will cease to accrue on
the Notes or the portions of Notes called for redemption or purchase. If a Note
is redeemed or purchased on or after an interest record date but on or prior to
the related interest payment date, then any accrued and unpaid interest shall be
paid 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 will issue and, upon receipt of an Authentication Order, the Trustee
will authenticate for the Holder at the expense of the Company a new Note equal
in principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

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 of assets. The Asset Sale Offer will 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 will 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 will be made in the same manner as interest payments are
made.

                                       54
<PAGE>

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

         Upon the commencement of an Asset Sale Offer, the Company will send, by
first class mail, a notice to the Trustee and each of the Holders. The notice
will contain all instructions and materials necessary to enable such Holders to
tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the
terms of the Asset Sale Offer, will 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 will remain open;

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

                  (3) that any Note not tendered or accepted for payment will
         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 will
         cease to accrue interest after the Purchase Date;

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

                  (6) that Holders electing to have Notes purchased pursuant to
         any Asset Sale Offer will be required to surrender the Note, with the
         form entitled "Option of Holder to Elect Purchase" attached to the
         Notes 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 will be entitled to withdraw their election
         if the Company, the Depositary or the Paying Agent, as the case may be,
         receives, not later than 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 thereof exceeds the
         Offer Amount, the Company will 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, will be purchased); and

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

         On or before the Purchase Date, the 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 will
deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officers' Certificate stating that such Notes or portions
thereof were accepted for payment by the Company in

                                       55

accordance with the terms of this Section 3.09. The Company, the Depositary or
the Paying Agent, as the case may be, will promptly (but in any case not later
than five days after the Purchase Date) mail or deliver to each tendering Holder
an amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase, and the Company, will promptly issue a new
Note, and the Trustee, upon written request from the Company will authenticate
and mail or deliver (or cause to be transferred by book entry) such new Note to
such Holder, in a principal amount equal to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by
the Company to the Holder thereof. The Company will 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.

any, and interest and Liquidated Damages, if any, on the Notes on the dates and

registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any

fails to maintain any such required office or agency or fails to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee.

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

         year of the date of payment, purchase, redemption, defeasance,
         acquisition or retirement; or

                  (4) make any Restricted Investment

(all such payments and other actions set forth in these clauses (1) through (4)
above being collectively referred to as "Restricted Payments"), unless, at the
time of and 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;
         and

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

                  (3) such Restricted Payment, together with the aggregate

         Restricted Subsidiaries since the date of this Indenture (excluding
         Restricted Payments permitted by clauses (2), (3), (4), (6), (7), (8),
         (9) and (10) of paragraph (b) below), is less than the sum, without
         duplication, of:

                           (a) 50% of the Consolidated Net Income of the 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
         financial statements are publicly 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 been converted
         into or exchanged for such Equity Interests (other than Equity
         Interests (or Disqualified Stock or debt securities) sold to a
         Subsidiary of the Company), plus

                           (c) 100% of the aggregate net cash proceeds received
         upon the sale or other disposition of any Investment (other than a
         Permitted Investment) made since the date of this Indenture; plus the
         net reduction in Investments (other than Permitted Investments) in any
         Person resulting from dividends, repayments of loans or advances or
         other transfers of assets subsequent to the date of this Indenture, in
         each case to the Company or any Restricted Subsidiary from such Person;
         plus to the extent that the ability to make Restricted Payments was
         reduced as the result of the designation of an Unrestricted Subsidiary,
         the portion (proportionate to the Company's Equity Interest in such
         Subsidiary) of the Fair Market Value of the net assets of such
         Unrestricted Subsidiary at the time such Unrestricted Subsidiary is
         redesignated, or liquidated or merged into, a Restricted Subsidiary;
         provided, in each case, that the foregoing may not exceed, in the

                                       59

         aggregate, the amount of all Investments which previously reduced the
         ability to make Restricted Payments, plus

                           (d) 50% of any dividends received by the Company or a
         Restricted Subsidiary of the Company that is a Guarantor after the date
         of this Indenture from an Unrestricted Subsidiary of the Company, to
         the extent that such dividends were not otherwise included in
         Consolidated Net Income of the Company for such period.

         (b)      The provisions of Section 4.07(a) will 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;

         Interests of the Company (other than Disqualified Stock) or from the
         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 will be excluded from clause (3) (b) of the
         preceding paragraph;

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

                  (4) the payment of any dividend (or, in the case of any
         partnership or limited liability company, any similar distribution) by
         a Restricted Subsidiary of the Company to the holders of its Equity
         Interests on a pro rata basis;

                  (5) so long as no Default has occurred and is continuing or
         would be caused thereby, (a) the repurchase, redemption or other
         acquisition or retirement for value of any Equity Interests of the
         Company or any Restricted Subsidiary of the Company held by any current
         or former officer, director or employee of the Company or any of its

         similar agreement, employee benefit plan or (b) the cancellation of
         Indebtedness owing to the Company or any of its Restricted Subsidiaries
         from any current or former officer, director or employee of the Company
         or any of its Restricted Subsidiaries in connection with a repurchase
         of Equity Interests of the Company or any of its Restricted
         Subsidiaries; provided that the aggregate price paid for the actions in
         clause (a) may not exceed $1.0 million in any twelve-month period and
         $5.0 million in the aggregate since the date of this Indenture;
         provided, further that (i) such amount in any calendar year may be
         increased by the cash proceeds of "key man" life insurance policies
         received by the Company and its Restricted Subsidiaries after the date
         of this Indenture less any amount previously applied to the making of
         Restricted Payments pursuant to this clause (5) and (ii) cancellation
         of the Indebtedness owing to the Company from employees, officers,
         directors and consultants of the Company or any of its Restricted

         Company from such Persons shall be permitted under this clause (5) as
         if it were a repurchase, redemption, acquisition or retirement for
         value subject hereto;

         a portion of the exercise price of those stock options;

                  (7) so long as no Default has occurred and is continuing or
         would be caused thereby, the declaration and payment of regularly
         scheduled or accrued dividends to holders of any class or series of
         Disqualified Stock of the Company or any Restricted Subsidiary of the
         Company issued on or after the date of this Indenture in accordance

         other retirement for a nominal value per right of any rights granted to
         all the holders of Capital Stock of the Company pursuant to any
         shareholders' rights plan adopted for the purpose of protecting
         shareholders from unfair takeover tactics; provided that any such
         purchase, redemption, acquisition, cancellation or other retirement of
         such rights is not for the purpose of evading the limitations of this
         covenant (all as determined in good faith by the Board of Directors of
         the Company);

                  (11) so long as no Default has occurred and is continuing or
         would be caused thereby, upon the occurrence of a Change of Control and
         after the completion of the offer to repurchase the Notes pursuant to
         the provisions of Section 4.15 hereof (including the purchase of all
         Notes tendered), any purchase, defeasance, retirement, redemption or
         other acquisition of Capital Stock or Indebtedness that is

         result of such Change of Control; and

                  (12) so long as no Default has occurred and is continuing or
         would be caused thereby, other Restricted Payments in an aggregate
         amount not to exceed $50.0 million since the date of this Indenture.

         The amount of all Restricted Payments (other than cash) will be the
Fair Market Value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The Fair Market Value of any assets or securities that are required to be valued
by this Section 4.07 will be determined by the Board of Directors of the Company
whose resolution with respect thereto shall be delivered to the Trustee. The
Board of Directors' determination must be based upon an opinion or appraisal
issued by an accounting, appraisal or investment banking firm of national
standing if the Fair Market Value exceeds $35.0 million.

         those agreements; provided that such amendments, modifications,
         restatements, renewals, increases, supplements, refundings,
         replacements or refinancings are no more restrictive, taken as a whole,
         with respect to such dividend and other payment restrictions than those
         contained in those agreements on the date of this Indenture;

                  (2) this Indenture, the Notes, the Security Documents and the
         Subsidiary Guarantees (including the Exchange Notes and related

         restrictions contained in the agreements governing such Permitted
         Refinancing Indebtedness are not materially more restrictive, taken as
         a whole, than those contained in the agreements governing the
         Indebtedness being refinanced;

                  (8) Liens permitted to be incurred under the provisions of
         Section 4.12 hereof that limit the right of the debtor to dispose of

         provided that such agreement prohibits the encumbrance of solely the
         property or assets of the Company or such Restricted Subsidiary that
         are the subject of that agreement, the payment rights arising

         contemplation of such acquisition), which encumbrance or restriction is
         not applicable to any Person, or the properties or assets of any
         Person, other than the Person, or the property or assets of the Person,
         so acquired; provided that, in the case of Indebtedness, such
         Indebtedness was permitted by the terms of this Indenture to be
         incurred;

                  (13) Indebtedness of a Restricted Subsidiary of the Company
         existing at the time it became a Restricted Subsidiary if such
         restriction was not created in connection with or in anticipation of

         Restricted Subsidiary became a Restricted Subsidiary or was acquired by
         the Company;

                  (14) with respect to clause (3) of Section 4.08(a) hereof
         only, restrictions encumbering property at the time such property was
         acquired by the Company or any of its Restricted Subsidiaries, so long
         as such restriction relates solely to the property so acquired and was

         this Section 4.08(b); provided that such amendments, modifications,
         restatements, renewals, increases, supplements, refundings,
         replacements or refinancings are, in the good faith judgment of the
         Company's Board of Directors, no more restrictive with respect to such
         dividend and other payment restrictions than those contained in the
         dividend or other payment restrictions prior to such amendment,
         modification, restatement, renewals, increase, supplement, refunding,
         replacement or refinancing.

Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt), and the Company will not issue any
Disqualified Stock and will not permit any of its Restricted Subsidiaries to
issue any shares of preferred stock; provided, however, that the Company may
incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and
the Guarantors may incur Indebtedness or issue preferred stock, if the Fixed
Charge Coverage Ratio for the Company's most recently ended four full fiscal
quarters for which financial statements are publicly available immediately
preceding the date on which such additional Indebtedness is incurred or such
Disqualified Stock or preferred stock is issued would have been at least 2.0 to
1, determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred or
Disqualified Stock or the preferred stock had been issued, as the case may be,
at the beginning of such four-quarter period.

         Sales (other than Excluded Proceeds) and Casualty Events in accordance
         with Section 4.10 hereof (excluding temporary reductions in revolving
         credit borrowings as contemplated by Section 4.10 hereof);

         the Registration Rights Agreement;

                  (4) the incurrence by the Company or any of its Restricted
         Subsidiaries of Indebtedness represented by Capital Lease Obligations,

         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), (11), (13) or (16) of

                  (6) the incurrence by the Company or any of its Restricted
         Subsidiaries of intercompany Indebtedness between or among the Company
         and any of its Restricted Subsidiaries; provided, however, that:

                           (a) if the Company or any Guarantor is the obligor on
         such Indebtedness and the payee is not the Company or a Guarantor, such
         Indebtedness must be expressly subordinated to the prior payment in
         full in cash of all Obligations then due with respect to the Notes, in
         the case of the Company, or the Subsidiary Guarantee, in the case of a
         Guarantor; and

                                       64
<PAGE>

                           (b) (i) any subsequent issuance or transfer of Equity
         Interests that results in any such Indebtedness being held by a Person
         other than the Company or a Restricted Subsidiary of the Company and
         (ii) any sale or other transfer of any such Indebtedness to a Person
         that is not either the Company or a Restricted Subsidiary of the
         Company; will be deemed, in each case, to constitute an incurrence of
         such Indebtedness by the Company or such Restricted Subsidiary, as the
         case may be, that was not permitted by this clause (6);

                  (7) the issuance by any of the Company's Restricted
         Subsidiaries to the Company or to any of its Restricted Subsidiaries of
         shares of preferred stock; provided, however, that:

                           (a) any subsequent issuance or transfer of Equity
         Interests that results in any such preferred stock being held by a
         Person other than the Company or a Restricted Subsidiary of the
         Company; and

                           (b) any sale or other transfer of any such preferred
         stock to a Person that is not either the Company or a Restricted
         Subsidiary of the Company;

will be deemed, in each case, to constitute an issuance of such preferred stock
by such Restricted Subsidiary that was not permitted by this clause (7);

                  (8) the incurrence by the Company or any of its Restricted
         Subsidiaries of Hedging Obligations in the ordinary course of business
         and not for speculative purposes;

                  (9) the guarantee by (i) the Company or any of the Guarantors
         of Indebtedness of the Company or a Restricted Subsidiary of the
         Company that was permitted to be incurred by another provision of this
         covenant; (ii) any of the Excluded Project Subsidiaries of Indebtedness
         of any other Excluded Project Subsidiary; and (iii) any of the Excluded
         Foreign Subsidiaries of Indebtedness of any other Excluded Foreign
         Subsidiary; provided that if the Indebtedness being guaranteed is
         subordinated to or pari passu with the Notes, then the guarantee shall
         be subordinated to the same extent as the Indebtedness guaranteed;

                  (10) 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
         (except in the case of daylight overdrafts) inadvertently drawn against
         insufficient funds in the ordinary course of business, so long as such
         Indebtedness is covered within five Business Days;

                  (11) the Xcel Note and the Creditor Notes, if any;

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

                  (13) the incurrence of Additional Non-Recourse Debt by any
         Excluded Subsidiary if, immediately after giving effect to the
         incurrence of such Additional Non-Recourse Debt and the application of
         the proceeds therefrom, the Company's pro forma Secured Leverage Ratio
         would not exceed 2.75 to 1.0;

                  (14) the incurrence of Indebtedness that may be deemed to
         arise as a result of agreements of the Company or any Restricted
         Subsidiary of the Company providing for

                                       65
<PAGE>

         indemnification, adjustment of purchase price or any similar
         obligations, in each case, incurred in connection with the disposition
         of any business, assets or Equity Interests of any Subsidiary; provided
         that the aggregate maximum liability associated with such provisions
         may not exceed the gross proceeds (including non-cash proceeds) of such
         disposition;

                  (15) the incurrence by the Company or any Restricted
         Subsidiary of the Company of Indebtedness represented by letters of
         credit, guarantees of Indebtedness or other similar instruments to the
         extent (i) such instruments are cash collateralized and (ii) the
         Company or such Restricted Subsidiary would have been permitted to
         expend the funds used to cash collateralize such instrument directly
         under the terms of this Indenture; and

                  (16) the incurrence by the Company and/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 refund, refinance, replace, defease or discharge any Indebtedness
         incurred pursuant to this clause (16), not to exceed $250.0 million.

         The Company will not incur, and will 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 Subsidiary Guarantee on substantially identical
terms; provided, however, that no Indebtedness will 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
first or junior Lien basis.

         For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (16) above,
or is entitled to be incurred pursuant to Section 4.09(a), the Company will be
permitted to classify such item of Indebtedness on the date of its incurrence,
or later reclassify all or a portion of such item of Indebtedness, in any manner
that complies with this Section 4.09. Indebtedness under Credit Facilities
outstanding on the date on which Notes are first issued and authenticated under
this Indenture will initially be deemed to have been incurred on such date in
reliance on the exception provided by clause (1) of the definition of Permitted
Debt. The accrual of interest, the accretion or amortization of original issue
discount, the payment of interest on any Indebtedness in the form of additional
Indebtedness with the same terms, and the payment of dividends on Disqualified
Stock in the form of additional shares of the same class of Disqualified Stock
will not be deemed to be an incurrence of Indebtedness or an issuance of
Disqualified Stock for purposes of this Section 4.09; provided, in each such
case, that the amount thereof is included in Fixed Charges of the Company as
accrued.

         For purposes of determining compliance with any U.S. dollar-denominated
restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency will be
calculated based on the relevant currency exchange rate in effect on the date
such Indebtedness was incurred; provided that if such Indebtedness is incurred
to refinance other Indebtedness denominated in a foreign currency, and such
refinancing would cause the applicable U.S. dollar-dominated restriction to be
exceeded if calculated at the relevant currency exchange rate in effect on the
date of such refinancing, such U.S. dollar-dominated restriction shall be deemed
not to have been exceeded so long as the principal amount of such refinancing
Indebtedness does not exceed the principal amount of the Indebtedness being
refinanced.

         The amount of any Indebtedness outstanding as of any date will be:

                                       66
<PAGE>

                  (1) the accreted value of the Indebtedness, in the case of any
         Indebtedness issued with original issue discount;

                  (2) the principal amount of the Indebtedness, in the case of
         any other Indebtedness; and

                  (3) in respect of Indebtedness of another Person secured by a
         Lien on the assets of the specified Person, the lesser of:

                           (a) the Fair Market Value of such asset at the date
         of determination, and

                           (b) the amount of the Indebtedness of the other
         Person;

provided that any changes in any of the above shall not give rise to a default
under this Section 4.09.

Section 4.10 Asset Sales.

         (a)      The Company will not, and will not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale (including a Sale of
Collateral) 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 or, in the case of Specified Joint
         Venture Sales, receives consideration at least equal to the value
         prescribed by the agreements relating to such specified joint ventures
         as in effect on the date of this Indenture;

                  (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. For purposes of this provision, each of the following will be
         deemed to be cash:

                           (a) any liabilities, as shown on the Company's most
         recent consolidated balance sheet, of the Company or any Restricted
         Subsidiary (other than contingent liabilities and liabilities that are
         by their terms subordinated to the Notes or any Subsidiary Guarantee)
         that are assumed by the transferee of any such assets pursuant to a
         customary novation 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 converted by the Company or such Restricted
         Subsidiary into cash within 180 days of the receipt of such securities,
         notes or other obligations, to the extent of the cash received in that
         conversion; and

                           (c) except in the case of a Sale of Collateral, any
         stock or assets of the kind referred to in clauses (3) or (5) of the
         next paragraph of this Section 4.10; and

                  (3) in the case of a Sale of Collateral, the Company (or the
         Restricted Subsidiary, as the case may be) will deposit the Net
         Proceeds (other than Excluded Proceeds) as cash collateral in a
         segregated account held by the Collateral Trustee or its agent to
         secure the Secured Obligations.

         Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, other than Excluded Proceeds and other than Net Proceeds from a Sale of
Collateral, the Company (or the applicable Restricted Subsidiary, as the case
may be) may apply those Net Proceeds:

                                       67
<PAGE>

                  (1) to repay Priority Lien Debt and, if such Priority Lien
         Debt is revolving credit Indebtedness, to correspondingly reduce
         commitments with respect thereto;

                  (2) in the case of a sale of assets pledged to secured
         Indebtedness (including Capital Lease Obligations) other than Secured
         Debt, to repay the Indebtedness secured by those assets;

                  (3) to acquire all or substantially all of the assets of, or
         any Capital Stock of, another Person engaged primarily in a Permitted
         Business, if, after giving effect to any such acquisition of Capital
         Stock, such Person is or becomes a Wholly-Owned Subsidiary of the
         Company;

                  (4) to make a capital expenditure;

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

                  (6) any combination of the foregoing.

Pending the final application of any such Net Proceeds, the Company may
temporarily reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by this Indenture.

         Within 365 days after the receipt of any Net Proceeds from an Asset
Sale that constitutes a Sale of Collateral, other than Excluded Proceeds, or
from a Casualty Event, the Company (or the Restricted Subsidiary that owned
those assets, as the case may be) may apply those Net Proceeds to purchase other
assets (which may include Capital Stock) that would constitute Collateral or to
repay Priority Lien Debt and, if such Priority Lien Debt is revolving credit
Indebtedness, to correspondingly reduce commitments with respect thereto.

         Any Net Proceeds from Asset Sales (including Sales of Collateral but
excluding Excluded Proceeds) or Casualty Events that are not applied or invested
as provided in the preceding paragraphs will constitute "Excess Proceeds." When
the aggregate amount of Excess Proceeds exceeds $50.0 million, within fifteen
days thereof, the Company will make an Asset Sale Offer to all Holders of Notes
and all holders of other Parity Lien Debt 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 to purchase the maximum principal amount of
Notes and such Parity Lien Debt that may be purchased out of the Excess
Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of
principal amount plus accrued and unpaid interest and Liquidated Damages, if
any, to the date of purchase, and will 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 Parity Lien Debt
tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the
applicable trustee will select the Notes and such other Parity Lien Debt to be
purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds will be reset at zero.

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

Section 4.11 Transactions with Affiliates.

         (a)      The Company will not, and will 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 (as reasonably determined by 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 $10.0 million, a resolution of the
                  Board of Directors of the Company set forth in an Officers'
                  Certificate certifying that such Affiliate Transaction
                  complies with clause (1) of Section 4.11(a) and that such
                  Affiliate Transaction has been approved by a majority of the
                  disinterested members of such Board of Directors; and

                           (B)      with respect to any Affiliate Transaction or
                  series of related Affiliate Transactions involving aggregate
                  consideration in excess of $35.0 million, an opinion as to the
                  fairness to the Company or such Restricted Subsidiary of such
                  Affiliate Transaction from a financial point of view issued by
                  an accounting, appraisal or investment banking firm of
                  national standing.

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

                  (1) any employment agreement or director's engagement
         agreement, employee benefit 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 or
         approved by the Board of Directors of the Company in good faith;

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

                  (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 or its Restricted Subsidiaries to Affiliates of
         the Company;

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

                                       69
<PAGE>

                  (7) any agreement in effect as of the date of this Indenture
         or any amendment thereto or replacement thereof and any transaction
         contemplated thereby or permitted thereunder, so long as any such
         amendment or replacement agreement taken as a whole is not more
         disadvantageous to the Holders than the original agreement as in effect
         on the date of this Indenture;

                  (8) payments or advances to employees or consultants that are
         incurred in the ordinary course of business or that are approved by the
         Board of Directors of the Company in good faith;

                  (9) the existence of, or the performance by the Company or any
         of its Restricted Subsidiaries of its obligations under the terms of,
         any stockholders agreement (including any registration rights agreement
         or purchase agreement related thereto) to which it is a party as of the
         date of this Indenture and any similar agreements which it may enter
         into thereafter; provided, however, that the existence of, or the
         performance by the Company or any of its Restricted Subsidiaries of
         obligations under, any future amendment to any such existing agreement
         or under any similar agreement entered into after the date of this
         Indenture shall only be permitted by this clause (9) to the extent that
         the terms of any such amendment or new agreement are not otherwise more
         disadvantageous to the Holders of the Notes in any material respect;

                  (10) transactions permitted by, and complying with, the
         provisions of Section 5.01 hereof;

                  (11) transactions with customers, clients, suppliers, joint
         venture partners or purchasers or sellers of goods or services, in each
         case, in the ordinary course of business (including pursuant to joint
         venture agreements) and otherwise in compliance with the terms of this
         Indenture that are fair to the Company and its Restricted Subsidiaries,
         in the reasonable determination of the Board of Directors of the
         Company or the senior management thereof, or are on terms not
         materially less favorable taken as a whole as might reasonably have
         been obtained at such time from an unaffiliated party;

                  (12) any repurchase, redemption or other retirement of Capital
         Stock of the Company held by employees of the Company or any of its
         Subsidiaries at a price not in excess of the Fair Market Value thereof
         and, if greater than $1.0 million, approved by the Board of Directors
         of the Company;

                  (13) loans or advances to employees or consultants in the
         ordinary course of business not to exceed $2.0 million in the aggregate
         at any one time outstanding;

                  (14) the Reorganization Events and the Refinancing
         Transactions and the payment of all fees and expenses related thereto;
         and

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

Section 4.12 Liens.

         The Company will not, and will 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.

         The Company will not, and will 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 Parity
Lien Debt, unless (1) such Lien secures all Parity Lien Obligations (including
the Notes) on

                                       70
<PAGE>

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.

Section 4.13 Business Activities.

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

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 of the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Subsidiaries, taken as a whole, and that the
loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

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

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

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

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

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

<PAGE>

                  (5) that Holders electing to have any Notes purchased pursuant
         to a Change of Control Offer will be required to surrender the Notes,
         with the form entitled "Option of Holder to Elect Purchase" attached to
         the Notes completed, or transfer by book-entry transfer, to the Paying
         Agent at the address specified in the notice prior to the close of
         business on the third Business Day preceding the Change of Control
         Payment Date;

                  (6) that Holders will be entitled to withdraw their election
         if the Paying Agent receives, not later than the close of business on
         the second Business Day preceding the Change of Control Payment Date, a
         telegram, telex, facsimile transmission or letter setting forth the
         name of the Holder, the principal amount of Notes delivered for
         purchase, and a statement that such Holder is withdrawing his election
         to have the Notes purchased; and

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

         The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change in Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of Sections 3.09, 4.10 or 4.15 of this Indenture, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under Section 3.09, 4.10 or this Section
4.15 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

                  (3) deliver or cause to be delivered to the Trustee the Notes
         so 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 will promptly mail (but in any case not later than
fifteen days after the Change of Control Payment Date) to each Holder of Notes
properly tendered the Change of Control Payment for such Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each new Note will be in a
principal amount of $1,000 or an integral multiple of $1,000. The Company will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

         (c)      Notwithstanding anything to the contrary in this Section 4.15,
the Company will not be required to make a Change of Control Offer upon a Change
of Control if (1) a third party makes the Change of Control Offer in the manner,
at the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.09 hereof 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 hereof, 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 will not, and will not permit any of its
Restricted Subsidiaries to, enter into any sale and leaseback transaction;
provided that the Company or any Guarantor may enter into a sale and leaseback
transaction if:

                  (1) the Company or that Guarantor, as applicable, 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) hereof and (b) incurred a Lien
         to secure such Indebtedness pursuant to the provisions of Section 4.12
         hereof;

                  (2) the gross cash proceeds of that sale and leaseback
         transaction are at least equal to the Fair Market Value of the property
         that is subject of that sale and leaseback transaction, as determined
         in good faith by the Board of Directors of the Company; and

                  (3) if such sale and leaseback transaction constitutes an
         Asset Sale, 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 hereof.

Section 4.17 Payments for Consent.

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

Section 4.18 Additional Subsidiary Guarantees.

         If the Company or any of its Restricted Subsidiaries acquires or
creates another Domestic Subsidiary (other than an Excluded Subsidiary) after
the date of this Indenture or if any Excluded Subsidiary that is a Domestic
Subsidiary ceases to be an Excluded Subsidiary after the date of this Indenture,
then such newly acquired or created Subsidiary, or former Excluded Subsidiary,
will become a Guarantor and execute a Subsidiary Guarantee pursuant to a
supplemental indenture in form and substance satisfactory to the Trustee and
deliver an Opinion of Counsel to the Trustee within thirty Business Days of the
date on which it was acquired or created or ceased to be an Excluded Subsidiary
to the effect that such supplemental indenture has been duly authorized,
executed and delivered by that Domestic Subsidiary and constitutes a valid and
binding agreement of that Domestic Subsidiary, enforceable in accordance with
its terms (subject to customary exceptions). The form of such Subsidiary
Guarantee is attached as Exhibit E hereto.

Section 4.19 Designation of Restricted and Unrestricted Subsidiaries.

         The Board of Directors of the Company 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 will be deemed to be an Investment made as of the time of the
designation and will reduce the amount available for Restricted Payments under
Section 4.07 hereof or under one or more clauses of the definition of Permitted
Investments, as determined by the Company. That designation will only be

                                       73
<PAGE>

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 of the Company may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation
would not cause a Default.

Section 4.20 Changes in Covenants When Notes Rated Investment Grade.

         (a)      If on any date following the date of this Indenture:

                  (1) the rating assigned to the Notes by each of S&P and
         Moody's is an Investment Grade Rating; 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 two paragraphs, Sections 4.10 (other than any
         provisions contained therein relating to the Sale of Collateral and the
         application of the proceeds therefrom), 4.07, 4.08, 4.09, 4.19, 4.11
         and clause (4) of Section 5.01 hereof (collectively, the "Suspended
         Covenants") shall be suspended as to the Notes.

         (b)      During any period that the foregoing covenants have been
suspended, the Company's Board of Directors may not designate any of its
Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.19 hereof or the
second paragraph of the definition of "Unrestricted Subsidiary."

         (c)      If at any time the Notes are downgraded from an Investment
Grade Rating by either S&P or Moody's, the Suspended Covenants will thereafter
be reinstated as if such covenants had never been suspended and be applicable
pursuant to the terms of this Indenture (including in connection with performing
any calculation or assessment to determine compliance with the terms of this
Indenture), unless and until the Notes subsequently attain an Investment Grade
Rating from each of S&P and Moody's (in which event the Suspended Covenants will
again be suspended for such time that the Notes maintain an Investment Grade
Rating from each of S&P and Moody's); provided, however, that no Default, Event
of Default or breach of any kind will be deemed to exist under this Indenture,
the Notes or the Subsidiary Guarantees with respect to the Suspended Covenants
based on, and none of the Company or any of its Subsidiaries will bear any
liability for, any actions taken or events occurring after the Notes attain an
Investment Grade Rating from each of S&P and Moody's and before any
reinstatement of the Suspended Covenants as provided above, or any actions taken
at any time pursuant to any contractual obligation arising prior to the
reinstatement, regardless of whether those actions or events would have been
permitted if the applicable Suspended Covenant had remained in effect during
such period.

         the United States or the District of Columbia; provided that if the

         District of Columbia that does not and will not have any material
         assets or operations shall become a co-issuer of the Notes pursuant to
         a supplemental indenture duly executed by the Trustee;

                  (2) the Person formed by or surviving any such consolidation

         after giving pro forma effect to such consolidation or merger and any
         related financing transactions as if the same had occurred at the

         actual Fixed Charge Coverage Ratio for the period.

         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.

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) the Company defaults for 30 days in the payment when due
         of interest on, or Liquidated Damages with respect to, the Notes;

                  (2) the Company defaults in the payment when due (at maturity,

         on the Notes;

                  (3) the Company or any of its Restricted Subsidiaries fails to

                  (5) a default occurs under any mortgage, indenture or
         instrument under which there may be issued or by which there may be

         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:

                           (A)      is caused by a failure to pay principal of,

                  the expiration of the grace period provided in such
                  Indebtedness on the date of such default (a "Payment
                  Default"); or

                  that are not parties to such Non-Recourse Debt becomes
                  directly or indirectly liable, including pursuant to any

                  (7) material breach by the Company or any of its Restricted

                  Subsidiaries) that, taken together, would constitute a
                  Significant Subsidiary in an involuntary case;

                           (B)      appoints a custodian of the Company or any
                  of its Restricted Subsidiaries (other than the Exempt
                  Subsidiaries) that is a Significant Subsidiary or any group of
                  Restricted Subsidiaries of the Company (other than the Exempt
                  Subsidiaries) that, taken together, would constitute a
                  Significant Subsidiary or for all or substantially all of the

                  property of the Company or any of its Restricted Subsidiaries
                  (other than the Exempt Subsidiaries) that is a Significant
                  Subsidiary or any group of Restricted Subsidiaries of the
                  Company (other than the Exempt Subsidiaries) that, taken
                  together, would constitute a Significant Subsidiary; or

                           (C)      orders the liquidation of the Company or any
                  of its Restricted Subsidiaries (other than the Exempt
                  Subsidiaries) that is a Significant Subsidiary or any group of
                  Restricted Subsidiaries of the Company (other than the Exempt
                  Subsidiaries) that, taken together, would constitute a
                  Significant Subsidiary;

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

Section 6.02 Acceleration.

         In the case of an Event of Default specified in clause (9) or (10) of
Section 6.01 hereof, with respect to the Company or any of its Restricted
Subsidiaries (other than Exempt Subsidiaries) that is a Significant Subsidiary
or any group of Restricted Subsidiaries of the Company (other than the Exempt
Subsidiaries) that, taken together, would constitute a Significant Subsidiary,
all outstanding Notes will become due and payable immediately without further
action or notice. If any other Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable immediately.

         The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration or waive any existing Default or Event of
Default and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default (except nonpayment of
principal, interest or premium or Liquidated Damages, if any, that has become
due solely because of the acceleration) have been cured or waived.

         If an Event of Default occurs on or after December 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 December 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 December 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):

Section 6.03 Other Remedies.

                                       78
<PAGE>

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal of, premium and
Liquidated Damages, if any, and interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture including, but not
limited to issuing a Notice of Actionable Default under the Collateral Trust
Agreement.

         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 written notice to the Trustee may on behalf of the
Holders of all of the Notes waive an existing Default or Event of Default and
its consequences hereunder, except a continuing Default or Event of Default in
the payment of the principal of, premium and Liquidated Damages, 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 including, but not limited to issuing a Notice of Actionable
Default under the Collateral Trust Agreement. 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 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
         that an Event of Default is continuing;

                  (2) 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 or Holders offer and, if requested, provide to
         the Trustee security or indemnity reasonably satisfactory to the
         Trustee against any loss, liability or expense;

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

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

                                       79
<PAGE>

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal of, premium and Liquidated
Damages, 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 and Liquidated Damages, 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, as administrative expenses associated with any such proceeding, 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.

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:

                                       80
<PAGE>

                  First: to the Trustee, its agents and attorneys for amounts
         due under Section 7.07 hereof, including payment of all compensation,
         expenses 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 and Liquidated Damages, if any, and
         interest, ratably, without preference or priority of any kind,
         according to the amounts due and payable on the Notes for principal,
         premium and Liquidated Damages, 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 will exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

         (b)      Except during the continuance of an Event of Default of which
a Responsible Officer has actual knowledge of or receives written notice:

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

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee will examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

                                       81
<PAGE>

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

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

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

                  (3) the Trustee will not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05 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 will require the Trustee to
expend or risk its own funds or incur any liability, financial or otherwise, in
the performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there is reasonable ground for believing that the repayment
of such funds or indemnity reasonably satisfactory to it against such risk or
liability is not reasonably assured to it, and none of the provisions contained
in this Indenture shall in any event require the Trustee to perform, or be
responsible or liable for the manner of performance of, any obligations of the
Company under this Indenture or any related document. The Trustee will be under
no obligation to exercise any of its rights and powers under this Indenture, or
to institute, conduct or defend any litigation hereunder or in relation hereto,
at the request, order or direction of any Holders, unless such Holder has
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense, which may be incurred therein or thereby.

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

         (g)      The Trustee shall not be a trustee for or have any fiduciary
obligation to any party hereto and no implied covenants or obligations shall be
read into this Indenture against the Trustee.

Section 7.02 Rights of Trustee.

         (a)      The Trustee may conclusively rely upon, and shall be fully
protected in relying 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
will 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 will be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

         (c)      The Trustee may act directly, or by or through its attorneys,
agents, custodians or nominees and will not be responsible for the misconduct or
negligence on the part of, or for the supervision of, any agent, attorney,
custodian or nominee appointed with due care.

                                       82
<PAGE>

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

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

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

         (g)      The Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such written investment direction. In
no event shall the Trustee be liable for the selection of investments or for
investment losses incurred thereon. The Trustee shall have no liability in
respect of losses incurred as a result of the liquidation of any such investment
prior to its stated maturity or the failure of a party directing such investment
to provide timely written investment direction.

         (h)      Neither the Trustee nor any of its officers, directors,
employees or agents shall be liable for any action taken or omitted under this
Indenture or in connection therewith except to the extent caused by the
Trustee's gross negligence or willful misconduct, as determined by the final
judgment of a court of competent jurisdiction, no longer subject to appeal or
review.

         (i)      The Company (for itself and any person or entity claiming
through it) hereby releases, waives, discharges, exculpates and covenants not to
sue the Trustee for any action taken or omitted under this Indenture except to
the extent caused by the Trustee's gross negligence or willful misconduct.

         (j)      Anything in this Indenture to the contrary notwithstanding, in
no event shall the Trustee be liable for special, indirect or consequential loss
or damage of any kind whatsoever (including but not limited to lost profits),
even if the Trustee has been advised of the likelihood of such loss or damage
and regardless of the form of action.

         (k)      The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, officers' certificate, or other
certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, appraisal, bond, debenture, note, coupon, security, or other
paper or document.

         (l)      The Trustee shall not be bound to ascertain or inquire as to
the performance or observance of any covenants, conditions or agreements on the
part of the Company, except as otherwise set forth herein, but the Trustee may
require of the Company full information and advice as to the performance of the
covenants, conditions and agreements contained herein and shall be entitled in
connection herewith to examine the books, records and premises of the Company.

         (m)      For so long as the Trustee shall serve as Registrar and Paying
Agent, it shall be afforded in such capacities, the same rights, protections,
immunities and indemnities provided to the Trustee herein.

         (n)      The permissive rights of the Trustee to do things enumerated
in this Indenture shall not be construed as a duty and the Trustee shall not be
answerable for other than its gross negligence or willful default.

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, apply to the SEC for
permission to continue as trustee (if this Indenture has been qualified under
the TIA) or resign. Any Agent may do the same with like rights and duties.

Section 7.04 Trustee's Disclaimer.

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

Section 7.05 Notice of Defaults.

         If a Default or Event of Default occurs and is continuing and if the
Trustee receives written notice of, or a Responsible Officer of the Trustee has
actual knowledge of, such Default or Event of Default, the Trustee will mail to
Holders of Notes a notice of the Default or Event of Default within 90 days
after it occurs. Except in the case of a Default or Event of Default in payment
of principal of, premium or Liquidated Damages, 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 will mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA Section 313(a) (but if no
event described in TIA Section 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also
will comply with TIA Section 313(b)(2). The Trustee will also transmit by mail
all reports as required by TIA Section 313(c).

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

Section 7.07 Compensation and Indemnity.

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

                                       84
<PAGE>

related document in addition to the compensation for its services. Such expenses
will include the compensation, disbursements and expenses of the Trustee's
agents and counsel.

         (b)      The Company and the Guarantors will indemnify and hold
harmless and, at their option, defend the Trustee and its officers, directors,
employees, representatives and agents against and reimburse it and them for any
obligation, injuries (to person, property, or natural resources), penalty,
action, suit, judgment, reasonable cost and expense (including reasonable
attorney's and agent's fees and expenses) and all losses, liabilities or
expenses incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture and any documents related
thereto, including the costs and expenses of enforcing this Indenture against
the Company and the Guarantors (including this Section 7.07) and defending
itself against any claim (whether asserted by the Company, the Guarantors, any
Holder or any other Person) or liability 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 gross negligence or
bad faith. The Trustee will notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company will not
relieve the Company or any of the Guarantors of their obligations hereunder. The
Company or such Guarantor will defend the claim and the Trustee will cooperate
in the defense. The Trustee may have separate counsel and the Company will pay
the reasonable fees and expenses of such counsel. Neither the Company nor any
Guarantor need pay for any settlement made without its consent, which consent
will not be unreasonably withheld.

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

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

         (e)      When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(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 or law relating to creditor rights generally.

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

Section 7.08 Replacement of Trustee.

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

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

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

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

                                       85
<PAGE>

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

                  (4) the Trustee becomes incapable of acting.

         (c)      If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company will promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in 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 hereof,
such Holder may petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor Trustee.

         (f)      A successor Trustee will deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the
successor Trustee will have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee will mail a notice of its succession
to Holders. The retiring Trustee will promptly transfer all property held by it
as Trustee to the successor Trustee, provided all fees, expenses and
indemnification amounts 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 will continue for the benefit of the
retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

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

Section 7.10 Eligibility; Disqualification.

         There will at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100.0
million (or $50.0 million, in the case of the initial Trustee) as set forth in
its most recent published annual report of condition.

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

Section 7.11 Preferential Collection of Claims Against Company.

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

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, and at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

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

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

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

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

                  (4) this Article 8.

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

Section 8.03 Covenant Defeasance.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be released from each of their obligations under the covenants contained in
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19
and 4.20 hereof and clause (4) of Section 5.01 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04
hereof are satisfied (hereinafter, "Covenant Defeasance"), and the Notes will
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but will continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes will not be deemed outstanding for accounting purposes). For this purpose,
Covenant Defeasance

                                       87
<PAGE>

means that, with respect to the outstanding Notes and Subsidiary Guarantees, the
Company and the Guarantors may omit to comply with and will have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply will
not constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes and
Subsidiary Guarantees will 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(8) hereof will not constitute
Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

         (a)      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 U.S. dollars,
         non-callable Government Securities, or a combination thereof, in such
         amounts as will be sufficient, in the opinion of a nationally
         recognized investment bank, appraisal firm, or firm of independent
         public accountants, to pay the principal of, premium and Liquidated
         Damages, 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 the Notes are being
         defeased to such maturity or to a particular redemption date;

                  (2) in the case of an election under Section 8.02 hereof, the
         Company must deliver to the Trustee an Opinion of Counsel 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 will not recognize income, gain or loss for
                  federal income tax purposes as a result of such Legal
                  Defeasance and will be subject to federal income tax on the
                  same amounts, in the same manner and at the same times as
                  would have been the case if such Legal Defeasance had not
                  occurred;

                  (3) in the case of an election under Section 8.03 hereof, the
         Company must deliver to the Trustee an Opinion of Counsel confirming
         that the Holders of the outstanding Notes will not recognize income,
         gain or loss for federal income tax purposes as a result of such
         Covenant Defeasance and will be subject to federal income tax on the
         same amounts, in the same manner and at the same times as would have
         been the case if such Covenant Defeasance had not occurred;

                  (4) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit (other than a Default or Event
         of Default resulting from the borrowing of funds to be applied to such
         deposit) and the deposit will not result in a breach or violation of,
         or constitute a default under, any other instrument to which the
         Company or any Guarantor is a party or by which the Company or any
         Guarantor is bound;

                                       88
<PAGE>

                  (5) such Legal Defeasance or Covenant Defeasance will not
         result in a breach or violation of, or constitute a default under, any
         material agreement or instrument (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.

         (b)      Upon the occurrence of a Legal Defeasance or a Covenant
Defeasance, the Collateral will be released from the Lien Securing the Notes
pursuant to Section 10.03 hereof.

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
will be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium and Liquidated Damages, if
any, and interest, but such money need not be segregated from other funds except
to the extent required by law.

         The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 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
will deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(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 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 or
Liquidated Damages, if any, or interest on any Note and remaining unclaimed for
two years after such principal, premium or Liquidated Damages, 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) will be discharged from such trust; and the
Holder of such Note will 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, and all liability of the Company as trustee
thereof, will thereupon cease;

                                       89
<PAGE>

provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, shall at the expense of the Company cause to be
published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which will not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the 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 and the Guarantors' obligations under this
Indenture and the Notes and the Subsidiary Guarantees will be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
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 or Liquidated Damages, if any, or interest on any Note following the
reinstatement of its obligations, the Company will 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, the
Guarantors 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 or to alter the provisions of Article 2
         hereof (including the related definitions) in a manner that does not
         materially adversely affect any Holder;

                  (3) to provide for the assumption of the Company's or a
         Guarantor's obligations to the Holders of the Notes by a successor to
         the Company pursuant to Article 5 or Article 11 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 such Holder;

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

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

                  (7) to conform the text of this Indenture, the Security
         Documents or the Notes to any provision of the "Description of Notes"
         section of the Company's Offering Memorandum, to the

                                       90
<PAGE>

         extent that such provision in that "Description of Notes" was intended
         to be a verbatim recitation of a provision of this Indenture, the
         Subsidiary Guarantees, the Security Documents or the Notes;

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

                  (9) to allow any Guarantor to execute a supplemental indenture
         and/or a Subsidiary Guarantee with respect to the Notes.

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

Section 9.02 With Consent of Holders of Notes.

         Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including, without limitation,
Section 3.09, 4.10 and 4.15 hereof) and the Notes with the consent of the
Holders of at least a majority in principal amount of the Notes then outstanding
voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium or Liquidated Damages, 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 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). Section 2.08 hereof shall determine which Notes are considered to be
"outstanding" for purposes of this Section 9.02.

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

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

         After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company will mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, will not,
however, in any way impair or affect the validity of any such amended or
supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the Notes then
outstanding voting as a single class may waive compliance in a particular
instance by

                                       91
<PAGE>

the Company with any provision of this Indenture or the Notes. However, without
the consent of each Holder affected, an amendment, supplement 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 premium or Liquidated Damages, if any, or interest 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 or
         Liquidated Damages, if any, on the Notes;

                  (7) waive a redemption payment with respect to any Note (other
         than a payment required by Sections 3.09, 4.10 or 4.15 hereof);

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

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

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

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and Effect of Consents.

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

Section 9.05 Notation on or Exchange of Notes.

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

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

Section 9.06 Trustee to Sign Amendments, etc.

         The Trustee will sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities, indemnities or immunities of the
Trustee; provided that any amendment or supplement that modifies in any way the
Trustee's duties, obligations or covenants hereunder shall be reasonably
satisfactory in form and substance to the Trustee. The Company may not sign an
amended or supplemental indenture until its Board of Directors approves it. In
executing any amended or supplemental indenture, the Trustee will be entitled to
receive and (subject to Section 7.01 hereof) will be fully protected in
conclusively 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 and an Officers' Certificate stating that such
supplement or amendment is not inconsistent with the terms of the Collateral
Trust Agreement or any Priority Lien Document (as defined in the Collateral
Trust Agreement).

Section 11.01 Execution and Delivery of Subsidiary Guarantee.

         To evidence its Subsidiary Guarantee, each Guarantor hereby agrees that
the Guarantee and Collateral Agreement substantially in the form attached as
Exhibit E hereto will be executed by an Officer of such Guarantor.

         In the event that the Company or any of its Restricted Subsidiaries
creates or acquires any Domestic Subsidiary after the date of this Indenture, if
required by Section 4.18 hereof, the Company will cause such Domestic Subsidiary
to comply with the provisions of Section 4.18 hereof and this Article 11, to the
extent applicable.

Section 11.02 Guarantors May Consolidate, etc., on Certain Terms.

         Except as otherwise provided in Section 11.03 hereof, no Guarantor may
sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person, other than the Company or another Guarantor,
unless:

                                       95
<PAGE>

                  (1) immediately after giving effect to such transaction, no
         Default or Event of Default exists; and

                  (2) either:

                           (a) subject to Section 11.03 hereof, the Person
         acquiring the property in any such sale or disposition or the Person
         formed by or surviving any such consolidation or merger unconditionally
         assumes all the obligations of that Guarantor, pursuant to supplemental
         agreements in form and substance reasonably satisfactory to the Trustee
         and the Collateral Trustee, under this Indenture, the Subsidiary
         Guarantee, the relevant Security Documents and the Registration Rights
         Agreement (unless all material obligations in that agreement have been
         performed) on the terms set forth herein or therein; and

                           (b) the Net Proceeds of such sale or other
         disposition are applied in accordance with the applicable provisions of
         this Indenture, including without limitation, Section 4.10 hereof.

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

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

Section 11.03 Releases.

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

<PAGE>

         (b)      Upon designation of any Guarantor as an Unrestricted
Subsidiary in accordance with the terms of this Indenture, such Guarantor will
be released and relieved of any obligations under its Subsidiary Guarantee.

         (c)      Upon Legal Defeasance in accordance with Article 8 hereof or
satisfaction and discharge of this Indenture in accordance with Article 12
hereof, each Guarantor will be released and relieved of any obligations under
its Subsidiary Guarantee.

         (d)      Upon a dissolution of any Guarantor that is permitted by the
terms of this Indenture, such Guarantor will be released and relieved of any
obligations under its Subsidiary Guarantee.

         Any Guarantor not released from its obligations under its Subsidiary
Guarantee as provided in this Section 11.03 will remain liable for the full
amount of principal of and interest on the Notes and for the other obligations
of any Guarantor as provided in the Guarantee and Collateral Agreement.

                           SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

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

                  (1) either:

                           (a) all Notes that have been authenticated (except
         lost, stolen or destroyed Notes that have been replaced or paid and
         Notes for whose payment money has theretofore been deposited in trust
         and thereafter repaid to the 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
         mailing of a notice of redemption or otherwise or will become due and
         payable within one year and the Company or any Guarantor has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust solely for the benefit of the Holders, cash in
         U.S. dollars, non-callable Government Securities, or a combination
         thereof, in such amounts as will be sufficient, without consideration
         of any reinvestment of interest, to pay and discharge the entire
         Indebtedness on the Notes not delivered to the Trustee for cancellation
         for principal, premium and Liquidated Damages, 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 (other than a Default or Event
         of Default resulting from the borrowing of funds to be applied to such
         deposit) and the deposit will not result in a breach or violation of,
         or constitute a default under, any other instrument to which the
         Company or any Guarantor is a party or by which the Company or any
         Guarantor is bound;

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

                                       97
<PAGE>

                  (4) the Company has delivered irrevocable written 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 Sections 12.02 and 8.06 will survive. In
addition, nothing in this Section 12.01 will be deemed to discharge those
provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

Section 12.02 Application of Trust Money.

         Subject to the provisions of Section 8.06 hereof, all money deposited
with the Trustee pursuant to Section 12.01 hereof 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 and
Liquidated Damages, if any) and interest for whose payment such money has been
deposited with the Trustee; but such money need not be segregated from other
funds except to the extent required by law.

         If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 12.01 hereof by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's and any Guarantor's obligations under this Indenture
and the Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.01 hereof; provided that if the Company has made any
payment of principal of, premium or Liquidated Damages, 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.

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

                  (1) INTEREST. NRG Energy, Inc., a Delaware corporation (the
         "Company"), promises to pay interest on the principal amount of this
         Note at 8% per annum from ________________, 20__ until maturity and
         shall pay the Liquidated Damages, if any, payable pursuant to Section 5
         of the Registration Rights Agreement referred to below. The Company
         will pay interest and Liquidated Damages, if any, semi-annually in
         arrears on June 15 and December 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 will accrue from the
         most recent date to which interest has been paid or, if no interest has
         been paid, from the date of issuance; provided that if there is no
         existing Default in the payment of interest, and if this Note is
         authenticated between a record date referred to on the face hereof and
         the next succeeding Interest Payment Date, interest shall accrue from
         such next succeeding Interest Payment Date; provided further that the
         first Interest Payment Date shall be June 15, 2004. The Company will
         pay interest (including post-petition interest in any proceeding under
         any Bankruptcy Law) on overdue principal and premium, if any, from time
         to time on demand at a rate that is 1% per annum in excess of the rate
         then in effect; it will pay interest (including post-petition interest
         in any proceeding under any Bankruptcy Law) on overdue installments of
         interest and Liquidated Damages, if any, (without regard to any
         applicable grace periods) from time to time on demand at the same rate
         to the extent lawful. Interest will be computed on the basis of a
         360-day year of twelve 30-day months.

                  (2) METHOD OF PAYMENT. The Company will pay interest on the
         Notes (except defaulted interest) and Liquidated Damages, if any, to
         the Persons who are registered Holders of Notes at the close of
         business on the June 1 or December 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 will be payable as to principal, premium and Liquidated Damages,
         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 and Liquidated
         Damages, if any, may be made by check mailed to the Holders at their
         addresses set forth in the register of Holders; provided that payment
         by wire transfer of immediately available funds will be required with
         respect to principal of and interest, premium and Liquidated Damages,
         if any, on, all Global Notes and all other Notes the Holders of which
         will have provided wire transfer instructions to the Company or the
         Paying Agent. Such payment will be in such coin or currency of the
         United States of America as at the time of payment is legal tender for
         payment of public and private debts.

                  (3) PAYING AGENT AND REGISTRAR. Initially, Law Debenture Trust
         Company of New York, the Trustee under the Indenture, will act as
         Paying Agent and Registrar. The Company

                                       A-3
<PAGE>

         may change any Paying Agent or Registrar without 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 December 23, 2003 (the "Indenture") among the Company, the
         Guarantors and the Trustee. The terms of the Notes include those stated
         in the Indenture and those made part of the Indenture by reference to
         the TIA (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 limited to $1.25 billion in aggregate
         principal amount. Additional Notes may be issued pursuant to the
         Indenture and will be part of the same series as the Initial Notes. The
         Notes are secured on a second-priority basis by security interests in
         the Collateral pursuant to the Security Documents referred to in the
         Indenture.

                  (5) OPTIONAL REDEMPTION.

         (a)      Except as set forth in subparagraph (b) of this Paragraph 5,
the Company will not have the option to redeem the Notes prior to December 15,
2008. On or after December 15, 2008, the Company will 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 redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest and Liquidated Damages, if any,
thereon to the applicable redemption date, if redeemed during the twelve-month
period beginning on December 15 of the years indicated below, subject to the
rights of Holders of the Notes on the relevant record date to receive interest
on the relevant interest payment date:

<TABLE>

2010.............................................    101.333%
2011 and thereafter..............................    100.000%
</TABLE>

         (b)      Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, at any time prior to December 15, 2006, the Company may on any one
or more occasions redeem up to 35% of the aggregate principal amount of Notes
issued under the Indenture with the net cash proceeds of one or more Equity
Offerings at a redemption price equal to 108% of the principal amount thereof,
plus accrued and unpaid interest and Liquidated Damages, if any; provided that
at least 65% in aggregate principal amount of the Notes originally issued under
the Indenture (excluding Notes held by the Company and its Subsidiaries) remains
outstanding immediately after the occurrence of such redemption and that such
redemption occurs within 45 days of the date of the closing of such Equity
Offering.

                  (6) MANDATORY REDEMPTION.

         The Company will not be required to make mandatory redemption payments
with respect to the Notes.

                  (7) REPURCHASE AT THE OPTION OF HOLDER.

                           (a) If there is a Change of Control, the Company will
         be required to make an offer (a "Change of Control Offer") to
         repurchase all or any part (equal to $1,000 or an integral

                                       A-4
<PAGE>

         multiple thereof) of each Holder's Notes at a purchase price equal to
         101% of the aggregate principal amount thereof plus accrued and unpaid
         interest and Liquidated Damages thereon, if any, to the date of
         purchase (the "Change of Control Payment"). Within 10 days following
         any Change of Control, the Company will mail a notice to each Holder
         setting forth the procedures governing the Change of Control Offer as
         required by the Indenture.

                           (b) If the Company or a Restricted Subsidiary of the
         Company consummates any Asset Sales, within fifteen days of each date
         on which the aggregate amount of Excess Proceeds exceeds $50.0 million,
         the Company will commence an offer to all Holders of Notes and all
         holders of other Indebtedness that is pari passu 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 (an "Asset Sale Offer") pursuant to Section 3.09 of the
         Indenture to purchase the maximum principal amount of Notes and other
         pari passu Indebtedness that may be purchased out of the Excess
         Proceeds at an offer price in cash in an amount equal to 100% of the
         principal amount thereof plus accrued and unpaid interest and
         Liquidated Damages thereon, if any, to the date fixed for the closing
         of such offer, in accordance with the procedures set forth in the
         Indenture. To the extent that the aggregate amount of Notes and other
         pari passu Indebtedness tendered pursuant to an Asset Sale Offer is
         less than the Excess Proceeds, the Company (or such Restricted
         Subsidiary) may use such deficiency for any purpose not otherwise
         prohibited by the Indenture. If the aggregate principal amount of Notes
         and other pari passu Indebtedness surrendered by holders thereof
         exceeds the amount of Excess Proceeds, the Trustee shall select the
         Notes and other pari passu Indebtedness to be purchased on a pro rata
         basis. Holders of Notes that are the subject of an offer to purchase
         will 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" attached to the
         Notes.

                  (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed
         at least 30 days but not more than 60 days before the redemption date
         to each Holder whose Notes are to be redeemed at its registered
         address, 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 or discharge of the
         Indenture. 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

                                       A-5
<PAGE>

         least a majority in principal amount of the then outstanding Notes
         voting as a single class, and any existing Default or Event of 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 voting as a single class. Without
         the consent of any Holder of a Note, the Indenture 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 or
         any Guarantor'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 TIA; 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 pursuant to the Indenture or any of
         the Security Documents; to conform the text of the Indenture, the
         Security Agreements or the Notes to any provision of the "Description
         of Notes" section of the Company's Offering Memorandum dated December
         17, 2003, relating to the initial offering of the Notes, to the extent
         that such provision in that "Description of Notes" was intended to be a
         verbatim recitation of a provision of the Indenture, the Subsidiary
         Guarantees, the Security Agreements or the Notes; to provide for the
         Issuance of Additional Notes in accordance with the limitations set
         forth in the Indenture; or to allow any Guarantor to execute a
         supplemental indenture to the Indenture and/or a Subsidiary Guarantee
         with respect to the Notes.

                  (12) DEFAULTS AND REMEDIES. Events of Default include: (i)
         default for 30 days in the payment when due of interest or Liquidated

         warranty or other agreement in the Indenture, the Notes or the Security
         Documents; (v) default under one or more instruments evidencing or
         securing Indebtedness of the Company or any of its Restricted
         Subsidiaries having an outstanding principal amount of $50.0 million or
         more that has resulted in the acceleration of the payment of such
         Indebtedness or failure to pay principal of, or interest or premium, if
         any, when due, subject to certain exceptions; (vi) certain judgments
         for the payment of money in an amount of $50.0 million or more or other
         judgments that, individually or in the aggregate, could reasonably be

         remain undischarged for a period of 30 consecutive days; (vii) a
         material breach by the Company or any of its Restricted Subsidiaries of
         any material representation or warranty or agreement in the Security

         Value of $25.0 million or more; (viii) except as permitted by the
         Indenture, any Subsidiary Guarantee shall be held in any judicial
         proceeding to be unenforceable or invalid or shall cease for any reason
         to be in full force and effect or any Guarantor (or any group of
         Guarantors) that constitutes a Significant Subsidiary, or any Person
         acting on behalf of any Guarantor (or any group of Guarantors) that
         constitutes a Significant Subsidiary, shall deny or disaffirm its or
         their obligations under its or their Subsidiary Guarantees; and (ix)
         certain events of bankruptcy or insolvency with respect to the Company
         or any of its Restricted Subsidiaries (other than Exempt Subsidiaries)
         that is a Significant Subsidiary or any group of Restricted
         Subsidiaries (other than Exempt Subsidiaries) that, when taken
         together, would constitute a Significant Subsidiary. If any Event of
         Default occurs and is

                                       A-6
<PAGE>

         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 will become due and payable without further action or
         notice. Holders may not enforce the Indenture or the Notes except as
         provided in the Indenture. Subject to certain limitations, Holders of a
         majority in principal amount of the then outstanding Notes may direct
         the Trustee in its exercise of any trust or power. The Trustee may
         withhold from Holders of the Notes notice of any continuing Default or
         Event of Default (except a Default or Event of Default relating to the
         payment of principal or interest) if it determines that withholding
         notice is in their interest. The Holders of a majority in aggregate
         principal amount of the Notes then outstanding by notice to the Trustee
         may on behalf of the Holders of all of the Notes waive any existing
         Default or Event of Default and its consequences under the Indenture
         except a continuing Default or Event of Default in the payment of
         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, to deliver to the Trustee a statement
         specifying such Default or Event of Default.

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

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

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

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

                  (17) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES
         AND RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to
         Holders of Notes under the Indenture, Holders of Restricted Global
         Notes and Restricted Definitive Notes will have all the rights set
         forth in the Registration Rights Agreement dated as of December 23,

                  (18) CUSIP NUMBERS. Pursuant to a recommendation promulgated
         by the Committee on Uniform Security Identification Procedures, the

         Trustee may use CUSIP numbers in notices of redemption as a

                                       A-7

         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.

                  (19) Guarantees. This Note shall be entitled to the benefits
         of the Subsidiary Guarantees made by the Guarantors pursuant to the
         Guarantee and Collateral Agreement. Additional Guarantors may be added
         and Guarantors may be released from their Subsidiary Guarantees as
         provided in the Indenture and the Subsidiary Guarantee.

charge a copy of the Indenture and/or the Registration Rights Agreement.

         (a) [ ] a beneficial interest in a Global Note, or

         (b) [ ] a Definitive Note,

         we confirm that:

         1.       We understand that any subsequent transfer of the Notes or any
interest therein is subject to certain restrictions and conditions set forth in
the Indenture and the undersigned agrees to be bound by, and not to resell,
pledge or otherwise transfer the Notes or any interest therein except in
compliance with, such restrictions and conditions and the Securities Act of
1933, as amended (the "Securities Act").

         2.       We understand that the offer and sale of the Notes has not
been registered under the Securities Act, and that the Notes and any interest
therein may not be offered or sold except as permitted in the following
sentence. We agree, on our own behalf and on behalf of any accounts for which we
are acting as hereinafter stated, that if we should sell the Notes or any
interest therein, we will do so only (A) to the Company or any subsidiary

"qualified institutional buyer" (as defined therein), (C) to an institutional
"accredited investor" (as defined below) that, prior to such transfer, furnishes
(or has furnished on its behalf by a U.S. broker-dealer) to you and to the
Company a signed letter substantially in the form of this letter and an Opinion
of Counsel in form reasonably acceptable to the Company to the effect that such

Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions. We further understand that the Notes purchased by us
will bear a legend to the foregoing effect.

         4.       We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Notes, and
we and any accounts for which we are acting are each able to bear the economic
risk of our or its investment.

         5.       We are acquiring the Notes or beneficial interest therein
purchased by us for our own account or for one or more accounts (each of which
is an institutional "accredited investor") as to each of which we exercise sole
investment discretion.

                    TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

         SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of
________________, 200__, among __________________ (the "Guaranteeing
Subsidiary"), a subsidiary of NRG Energy, Inc. (or its permitted successor), a
Delaware corporation (the "Company"), the Company, the other Guarantors (as
defined in the Indenture referred to herein) and Law Debenture Trust Company of
New York, as trustee under the Indenture referred to below (the "Trustee").

                               W I T N E S S E T H

         WHEREAS, the Company has heretofore executed and delivered to the
Trustee an indenture (the "Indenture"), dated as of December 23, 2003 providing
for the issuance of ___% Second Priority Senior Secured Notes due 2013 (the
"Notes");

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

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

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

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

         2.       AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby
agrees to provide an unconditional Guarantee on the terms and subject to the
conditions set forth in the Subsidiary Guarantee and in this Indenture.

         4.       NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, incorporator, stockholder or agent of the
Guaranteeing Subsidiary, as such, shall have any liability for any obligations
of the Company or any Guaranteeing Subsidiary under the Notes, any Subsidiary
Guarantees, the Indenture or this Supplemental Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the Notes by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.
Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the SEC that such a waiver is against
public policy.

         5.       NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW
YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

         6.       COUNTERPARTS. The parties may sign any number of copies of
this Supplemental Indenture. Each signed copy shall be an original, but all of
them together represent the same agreement.

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

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

Indenture to be duly executed and attested, all as of the date first above
written.
