           sold in reliance on any exception under the Securities Act other than
           Regulation S and Rule 144A will be issued, and upon the request of

such other certifications and evidence as the Company may reasonably require)
that a Note is eligible for resale pursuant to Rule 144(k) under the Securities
Act (or a successor provision) and that the Restricted Legend is no longer
necessary or appropriate in order to ensure that subsequent transfers of the
Note (or a beneficial interest therein) are effected in compliance with the
Securities Act, or

                      (2) after an Initial Note or any Initial Additional Note
           is

                                 (x) sold pursuant to an effective registration
                      statement under the Securities Act, pursuant to the
                      Registration Rights Agreement or otherwise, or (y) is
                      validly tendered for exchange into an Exchange Note
                      pursuant to an Exchange Offer

the Company may instruct the Trustee to cancel the Note and issue to the Holder
thereof (or to its transferee) a new Note of like tenor and amount, registered

Additional Notes.

           (a) An Officer shall execute the Notes for the Company by facsimile

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

           (b) A Note will not be valid until the Trustee manually signs the
certificate of authentication on the Note, with the signature conclusive
evidence that the Note has been authenticated under the Indenture.

           (c) At any time and from time to time after the execution and
delivery of the Indenture, the Company may deliver Notes executed by the Company

                                       21
<PAGE>
                      (i) Initial Notes for original issue in the aggregate
           principal amount not to exceed $150,000,000,

                      (ii) Initial Additional Notes from time to time for
           original issue in aggregate principal amounts specified by the
           Company, and

                      (iii) Exchange Notes from time to time for issue in
           exchange for a like principal amount of Initial Notes or Initial
           Additional Notes

after the following conditions have been met:

                      (1) Receipt by the Trustee of an Officers' Certificate
           specifying

                                 (A) the amount of Notes to be authenticated and
                      the date on which the Notes are to be authenticated,

                                 (B) whether the Notes are to be Initial Notes
                      or Additional Notes or Exchange Notes,

                                 (C) in the case of Initial Additional Notes,
                      that the issuance of such Notes does not contravene any
                      provision of Article 4,

                                 (D) whether the Notes are to be issued as one
                      or more Global Notes or Certificated Notes, and

                                 (E) other information the Company may determine
                      to include or the Trustee may reasonably request.

                      (2) In the case of Initial Additional Notes, receipt by
           the Trustee of an Opinion of Counsel confirming that the Holders of
           the outstanding Notes will be subject to federal income tax in the
           same amounts, in the same manner and at the same times as would have
           been the case if such Additional Notes were not issued.

                      (3) In the case of Exchange Notes, effectiveness of an
           Exchange Offer Registration Statement and consummation of the
           exchange offer thereunder (and receipt by the Trustee of an Officers'
           Certificate to that effect). Initial Notes or Initial Additional
           Notes exchanged for Exchange Notes will be cancelled by the Trustee.

           Section 2.03. Registrar, Paying Agent and Authenticating Agent;
Paying Agent to Hold Money in Trust.

           (a) The Company may appoint one or more Registrars and one or more
Paying Agents, and the Trustee may appoint an Authenticating Agent, in which
case each reference in the Indenture to the Trustee in respect of the
obligations of the Trustee to be performed by that Agent will be deemed to be
references to the Agent. The Company may act as Registrar or (except for
purposes of Article 8) Paying Agent. In each case the Company and the Trustee
will enter into an appropriate agreement with the Agent implementing the
provisions of the Indenture


                                       22
<PAGE>
relating to the obligations of the Trustee to be performed by the Agent and the
related rights. The Company initially appoints the Trustee as Registrar and
Paying Agent.

           (b) 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
the Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or of interest on the Notes and will promptly notify
the Trustee of any default by the Company in making any such payment. The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee and account for any funds disbursed, and the Trustee may at any time
during the continuance of any payment default, upon written request to a Paying
Agent, require the Paying Agent to pay all money held by it to the Trustee and
to account for any funds disbursed. Upon doing so, the Paying Agent will have no
further liability for the money so paid over to the Trustee.

           Section 2.04. Replacement Notes.

           If a mutilated Note is surrendered to the Trustee or if a Holder
claims that its Note has been lost, destroyed or wrongfully taken, the Company
will issue and the Trustee will authenticate a replacement Note of like tenor
and principal amount and bearing a number not contemporaneously outstanding.
Every replacement Note is an additional obligation of the Company and entitled
to the benefits of the Indenture. If required by the Trustee or the Company, an
indemnity must be furnished that is sufficient in the judgment of both the
Trustee and the Company to protect the Company and the Trustee from any loss
they may suffer if a Note is replaced. The Company may charge the Holder for the
expenses of the Company and the Trustee in replacing a Note. In case the
mutilated, lost, destroyed or wrongfully taken Note has become or is about to
become due and payable, the Company in its discretion may pay the Note instead
of issuing a replacement Note.

           Section 2.05. Outstanding Notes.

           (a) Notes outstanding at any time are all Notes that have been
authenticated by the Trustee except for

                      (1) Notes cancelled by the Trustee or delivered to it for
           cancellation;

                      (2) any Note which has been replaced pursuant to Section
           2.04 unless and until the Trustee and the Company receive proof
           satisfactory to them that the replaced Note is held by a bona fide
           purchaser; and

                      (3) on or after the maturity date or any redemption date
           or date for repurchase of the Notes pursuant to an Asset Sale Offer
           or a Change of Control Offer, those Notes payable or to be redeemed
           or repurchased on that date for which the Trustee (or Paying Agent,
           other than the Company or an Affiliate of the Company) holds money
           sufficient to pay all amounts then due.

           (b) A Note does not cease to be outstanding because the Company or
one of its Affiliates holds the Note, provided that in determining whether the
Holders of the requisite principal amount of the outstanding Notes have given or
taken any request, demand,


                                       23
<PAGE>
authorization, direction, notice, consent, waiver or other action hereunder,
Notes owned by the Company or any Affiliate of the Company will be disregarded
and deemed not to be outstanding, (it being understood that in determining
whether the Trustee is protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other action, only Notes
which the Trustee knows to be so owned will be so disregarded). Notes so owned
which have been pledged in good faith may be regarded as outstanding if the
pledgee establishes to the satisfaction of the Trustee the pledgee's right so to
act with respect to such Notes and that the pledgee is not the Company or any
Affiliate of the Company.

           Section 2.06. Temporary Notes.

           Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee will authenticate temporary Notes. Temporary Notes will
be substantially in the form of definitive Notes but may have insertions,
substitutions, omissions and other variations determined to be appropriate by
the Officer executing the temporary Notes, as evidenced by the execution of the
temporary Notes. If temporary Notes are issued, the Company will cause
definitive Notes to be prepared without unreasonable delay. After the
preparation of definitive Notes, the temporary Notes will be exchangeable for
definitive Notes upon surrender of the temporary Notes at the office or agency
of the Company designated for the purpose pursuant to Section 4.02, without
charge to the Holder. Upon surrender for cancellation of any temporary Notes the
Company will execute and the Trustee will authenticate and deliver in exchange
therefor a like principal amount of definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes will be entitled to the
same benefits under the Indenture as definitive Notes.

           Section 2.07. Cancellation.

           The Company at any time may deliver to the Trustee for cancellation
any Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and may deliver to the Trustee for
cancellation any Notes previously authenticated hereunder which the Company has
not issued and sold. Any Registrar or the Paying Agent will forward to the
Trustee any Notes surrendered to it for transfer, exchange or payment. The
Trustee will cancel all Notes surrendered for transfer, exchange, payment or
cancellation and dispose of them in accordance with its document retention
procedures or the written instructions of the Company. The Company may not issue
new Notes to replace Notes it has paid in full or delivered to the Trustee for
cancellation.

           Section 2.08. CUSIP and CINS Numbers.

           The Company in issuing the Notes may use "CUSIP" and "CINS" numbers,
and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption
or exchange or in Offers to Purchase as a convenience to Holders, the notice to
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of redemption or
exchange. The Company will promptly notify the Trustee of any change in the
CUSIP or CINS numbers.


                                       24

      Section 2.09. Registration, Transfer and Exchange.

      (a) The Notes will be issued in registered form only, without coupons, and
the Company shall cause the Trustee to maintain a register (the "Register") of
the Notes, for registering the record ownership of the Notes by the Holders and
transfers and exchanges of the Notes.

      (b) (1) Each Global Note will be registered in the name of the Depositary
or its nominee and, so long as DTC is serving as the Depositary thereof, will
bear the DTC Legend.

            (2) Each Global Note will be delivered to the Trustee as custodian
      for the Depositary. Transfers of a Global Note (but not a beneficial
      interest therein) will be limited to transfers thereof in whole, but not
      in part, to the Depositary, its successors or their respective nominees,
      except (1) as set forth in Section 2.09(b)(4) and (2) transfers of
      portions thereof in the form of Certificated Notes may be made upon
      request of an Agent Member (for itself or on behalf of a beneficial owner)
      by written notice given to the Trustee by or on behalf of the Depositary
      in accordance with customary procedures of the Depositary and in
      compliance with this Section and Section 2.10.

            (3) Agent Members will have no rights under the Indenture with
      respect to any Global Note held on their behalf by the Depositary, and the
      Depositary shall be treated by the Company, the Trustee and any agent of
      the Company or the Trustee as the absolute owner and Holder of such Global
      Note for all purposes whatsoever. Notwithstanding the foregoing, the
      Depositary or its nominee may grant proxies and otherwise authorize any
      Person (including any Agent Member and any Person that holds a beneficial
      interest in a Global Note through an Agent Member) to take any action
      which a Holder is entitled to take under the Indenture or the Notes, and
      nothing herein will impair, as between the Depositary and its Agent
      Members, the operation of customary practices governing the exercise of
      the rights of a holder of any security.

            (4) If (x) the Depositary notifies the Company that it is unwilling
      or unable to continue as Depositary for a Global Note and a successor
      depositary is not appointed by the Company within 90 days of the notice or
      (y) an Event of Default has occurred and is continuing and the Trustee has
      received a request from the Depositary, the Trustee will promptly exchange
      each beneficial interest in the Global Note for one or more Certificated
      Notes in authorized denominations having an equal aggregate principal
      amount registered in the name of the owner of such beneficial interest, as
      identified to the Trustee by the Depositary, and thereupon the Global Note
      will be deemed canceled. If such Note does not bear the Restricted Legend,
      then the Certificated Notes issued in exchange therefor will not bear the
      Restricted Legend. If such Note bears the Restricted Legend, then the
      Certificated Notes issued in exchange therefor will bear the Restricted
      Legend, provided that any Holder of any such Certificated Note issued in
      exchange for a beneficial interest in a Temporary Offshore Global Note
      will have the right upon presentation to the Trustee of a duly completed
      Certificate of Beneficial Ownership after the Restricted Period to
      exchange such Certificated Note for a Certificated Note of like tenor and
      amount that does not bear the Restricted Legend, registered in the name of
      such Holder.

                                       25
<PAGE>
      (c) Each Certificated Note will be registered in the name of the holder
thereof or its nominee.

      (d) A Holder may transfer a Note (or a beneficial interest therein) to
another Person or exchange a Note (or a beneficial interest therein) for another
Note or Notes of any authorized denomination by presenting to the Trustee a
written request therefor stating the name of the proposed transferee or
requesting such an exchange, accompanied by any certification, opinion or other
document required by Section 2.10. The Trustee will promptly register any
transfer or exchange that meets the requirements of this Section by noting the
same in the register maintained by the Trustee for the purpose; provided that

            (x) no transfer or exchange will be effective until it is registered
      in such register and

            (y) the Trustee will not be required (i) to issue, register the
      transfer of or exchange any Note for a period of 15 days before a
      selection of Notes to be redeemed or repurchased, (ii) to register the
      transfer of or exchange any Note so selected for redemption or repurchase
      in whole or in part, except, in the case of a partial redemption or
      repurchase, that portion of any Note not being redeemed or repurchased, or
      (iii) if a redemption or a repurchase is to occur after a regular record
      date but on or before the corresponding related interest payment date, to
      register the transfer of or exchange any Note on or after the regular
      record date and before the date of redemption or repurchase. Prior to the
      registration of any transfer, the Company, the Trustee and their agents
      will treat the Person in whose name the Note is registered as the owner
      and Holder thereof for all purposes (whether or not the Note is overdue),
      and will not be affected by notice to the contrary.

      From time to time the Company will execute and the Trustee will
authenticate additional Notes as necessary in order to permit the registration
of a transfer or exchange in accordance with this Section.

      No service charge will be imposed in connection with any transfer or
exchange of any Note, 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 a transfer tax or other similar governmental charge
payable upon exchange pursuant to subsection (b)(4)).

(e) (1) Global Note to Global Note. If a beneficial interest in a Global Note is
transferred or exchanged for a beneficial interest in another Global Note, the
Trustee will (x) record a decrease in the principal amount of the Global Note
being transferred or exchanged equal to the principal amount of such transfer or
exchange and (y) record a like increase in the principal amount of the other
Global Note. Any beneficial interest in one Global Note that is transferred to a
Person who takes delivery in the form of an interest in another Global Note, or
exchanged for an interest in another Global Note, will, upon transfer or
exchange, cease to be an interest in such Global Note and become an interest in
the other Global Note and, accordingly, will thereafter be subject to all
transfer and exchange restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.


                                       26
<PAGE>
            (2) Global Note to Certificated Note. If a beneficial interest in a
      Global Note is transferred or exchanged for a Certificated Note, the
      Trustee will (x) record a decrease in the principal amount of such Global
      Note equal to the principal amount of such transfer or exchange and (y)
      deliver one or more new Certificated Notes in authorized denominations
      having an equal aggregate principal amount to the transferee (in the case
      of a transfer) or the owner of such beneficial interest (in the case of an
      exchange), registered in the name of such transferee or owner, as
      applicable.

            (3) Certificated Note to Global Note. If a Certificated Note is
      transferred or exchanged for a beneficial interest in a Global Note, the
      Trustee will (x) cancel such Certificated Note, (y) record an increase in
      the principal amount of such Global Note equal to the principal amount of
      such transfer or exchange and (z) in the event that such transfer or
      exchange involves less than the entire principal amount of the canceled
      Certificated Note, deliver to the Holder thereof one or more new
      Certificated Notes in authorized denominations having an aggregate
      principal amount equal to the untransferred or unexchanged portion of the

      involves a beneficial interest in a Temporary Offshore Global Note, the
      Person requesting the transfer must deliver or cause to be delivered to
      the Trustee a duly completed Rule 144A Certificate and/or an Opinion of

the Temporary Offshore Global Note Legend.

      (b) An owner of a beneficial interest in a Temporary Offshore Global Note
(or a Person acting on behalf of such an owner) may provide to the Trustee (and
the Trustee will accept) a duly completed Certificate of Beneficial Ownership at
any time after the Restricted Period (it being understood that the Trustee will
not accept any such certificate during the Restricted Period). Promptly after
acceptance of a Certificate of Beneficial Ownership with respect to such a
beneficial interest, the Trustee will cause such beneficial interest to be
exchanged for an equivalent beneficial interest in a Permanent Offshore Global
Note, and will (x) permanently reduce the principal amount of such Temporary
Offshore Global Note by the amount of such beneficial interest and (y) increase
the principal amount of such Permanent Offshore Global Note by the amount of
such beneficial interest.

      (c) Notwithstanding paragraph (b), if after the Restricted Period any
Initial Purchaser owns a beneficial interest in a Temporary Offshore Global
Note, such Initial Purchaser may, upon written request to the Trustee
accompanied by a certification as to its status as an Initial Purchaser,
exchange such beneficial interest for an equivalent beneficial interest in a
Permanent Offshore Global Note, and the Trustee will comply with such request
and will (x) permanently reduce the principal amount of such Temporary Offshore
Global Note by the amount of such beneficial interest and (y) increase the

interest until such beneficial interest is exchanged for an interest in a
Permanent Offshore Global Note or transferred for an interest in another Global
Note or a Certificated Note.

Section 2.12.  Defaulted Interest.

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

                            REDEMPTION AND PREPAYMENT

      Section 3.01. Notices to Trustee.

      If the Company elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, then it shall furnish to the Trustee, at
least 30 days but not more than 60 days before a redemption date, an Officers'
Certificate setting forth (i) the paragraph of the Notes and/or Section of this
Indenture pursuant to which the redemption shall occur, (ii) the redemption
date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption
price.

      Section 3.02. Selection of Notes to be Redeemed.

      If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption shall be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such other method as the Trustee shall deem fair and appropriate (and
in such manner as complies with applicable legal requirements); provided that no
Notes of $1,000 or less shall be redeemed in part. In the event of partial
redemption by lot, the particular Notes to be redeemed shall be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the
redemption date by the Trustee from the outstanding Notes not previously called
for redemption.

      The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof shall be


                                       30
<PAGE>
issued in the name of the Holder thereof upon cancellation of the original Note.
On and after the redemption date, unless the Company defaults in payment of the
redemption price, interest ceases to accrue on Notes or portions of them called
for redemption. Except as provided in this Section 3.02, provisions of this
Indenture that apply to Notes called for redemption also apply to portions of
Notes called for redemption.

      The provisions of the two preceding paragraphs of this Section 3.02 shall
not apply with respect to any redemption affecting only a Global Note, whether
such Global Note is to be redeemed in whole or in part. In case of any such
redemption in part, the unredeemed portion of the principal amount of the Global
Note shall be in an authorized denomination.

      Section 3.03. Notice of Redemption.

      Subject to the provisions of Section 3.09 hereof, at least 30 days but not
more than 60 days before a redemption date, the Company shall mail or cause to
be mailed, by first class mail, a notice of redemption to each Holder of Notes
to be redeemed at such Holder's registered address, provided, however, that the
Company shall provide notice to the Trustee pursuant to Section 3.01 hereof at
least three days (or such shorter period as shall be satisfactory to the
Trustee) prior to the mailing of the notice pursuant to this Section 3.03.

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

      (a) the redemption date;

      (b) the redemption price;

      (c) 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 Notes or Notes in principal amount equal to the
unredeemed portion shall be issued upon cancellation of the original Note;

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

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

      (f) that, unless the Company defaults in making such redemption payment,
interest on Notes called for redemption cease to accrue on and after the
redemption date;

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

      (h) 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.

      If any of the Notes to be redeemed is in the form of a Global Note, then
such notice shall be modified in form but not substance to the extent
appropriate to accord with the procedures of the Depositary applicable to
redemptions.


                                       31
<PAGE>
      At the Company's request and expense, the Trustee shall give the notice of
redemption in the Company's name; provided, however, that the Company shall have
delivered to the Trustee, at least 45 days (or such shorter period as shall be
satisfactory to the Trustee) 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 Price.

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

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

      Section 3.06. Notes Redeemed in Part.

      Upon surrender of a Note that is redeemed in part, the Company shall issue
and, upon the receipt of a written authentication order of the Company signed by
two Officers of the Company, the Trustee shall authenticate for the Holder at
the expense of the Company a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

of Notes remains outstanding immediately after the occurrence of such
redemption; and provided, further, that any such redemption shall occur within
60 days after the date of the closing of the related sale of such Equity
Interests.

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

      Section 3.08. Mandatory Redemption.

      Except as set forth under Sections 4.10 and 4.13 hereof, the Company shall
not be required to make mandatory redemption or sinking fund payments with
respect to the Notes.

      Section 3.09. Offer to Purchase by Application of Excess Proceeds.

      In the event that, pursuant to Section 4.10 hereof, the Company shall be
required to commence an offer to all Holders of Notes and, to the extent
required by the terms thereof, to all holders or lenders of other pari passu
Indebtedness, to repurchase Notes and any such pari passu Indebtedness (an
"Asset Sale Offer"), it shall follow the procedures specified below.

      The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer

if less than the Offer Amount has been tendered, all Notes tendered in response
to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the
same manner as interest payments are made.

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


                                       33

first class mail, a notice to the Trustee and each of the Holders. The notice

the Company, or a Paying Agent at the address specified in the notice at least
three Business Days before the Purchase Date;

      (g) that Holders shall be entitled to withdraw their election if the
Company, the Depositary or the Paying Agent, as the case may be, 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;

      (h) that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Company shall select the Notes to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Company so that only Notes in denominations of $1,000, or
integral multiples thereof, shall be purchased) in the manner provided in
Section 4.10; and

      (i) that Holders whose Notes were purchased only in part shall be issued

of its obligation to maintain an office or agency in the Borough of Manhattan,
the City of New York for such purposes. The Company shall give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

      Section 4.03. Reports.

      Notwithstanding that the Company may not be required to remain subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the
extent permitted by the Exchange Act, the Company shall file with the Commission
and provide, within 15 days after such filing, the Trustee and Holders and
prospective Holders (upon request) with the annual reports and the information,
documents and other reports that are specified in Sections 13 and 15(d) of the
Exchange Act (but without exhibits in the case of the Holders and prospective
Holders). In the event that the Company is not permitted to file such reports,
documents and information with the Commission, the Company will provide
substantially similar information to the Trustee, the Holders and prospective
Holders (upon request) as if the Company were subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act. The Company shall at
all times comply with TIA Section 314 (a).

      Section 4.04. Compliance Certificate.

      (a) The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year
has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge and what action the Company is
taking or proposes to take with respect thereto) and that to the best of his or
her knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of, premium, if any, or interest on the
Notes is prohibited or if such event has occurred, a description of the event
and what action the Company is taking or proposes to take with respect thereto.
As of the date hereof, the Company's fiscal year ends on December 31 of each
calendar year. In the event the Company changes its fiscal year, it shall
promptly notify the Trustee of such change.

      (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the fiscal year-end
financial statements delivered


                                       36
<PAGE>
pursuant to Section 4.03(a) above shall be accompanied by a written statement of
the Company's independent public accountants (who shall be a firm of established
national reputation) that in making the examination necessary for certification
of such financial statements, nothing has come to their attention that would
lead them to believe that the Company has violated any provisions of Article 4
or Article 5 hereof or, if any such violation has occurred, specifying the
nature and period of existence thereof, it being understood that such
accountants shall not be liable directly or indirectly to any Person for any
failure to obtain knowledge of any such violation.

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

      Section 4.05. Taxes.

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

      Section 4.06. Stay, Extension and Usury Laws

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

      Section 4.07. Restricted Payments.

      The Company shall not and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make
any other payment or distribution on account of the Company's Equity Interests
(including, without limitation, any payment to holders of the Company's Equity
Interests in connection with any merger or consolidation involving the Company)
or to the direct or indirect holders of the Company's Equity Interests in their
capacity as such (other than dividends or distributions payable in Equity
Interests (other than Disqualified Stock) of the Company); (ii) purchase, redeem
or otherwise acquire or retire for value any Equity Interests of the Company or
any direct or indirect parent or other Affiliate of the Company that is not a
Wholly Owned Restricted Subsidiary of the Company; (iii) make any principal
payment on, or purchase, redeem, defease or otherwise acquire or retire for
value any Indebtedness that is subordinated to the Notes, except at final
maturity; or (iv) make any Restricted Investment (all such payments and other
actions set forth in clauses (i) through (iv) above being collectively


                                       37
<PAGE>
referred to as "Restricted Payments"), unless, at the time of and after giving
effect to such Restricted Payment:

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

      (b) 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

      (c) such Restricted Payment, together with the aggregate of all other
Restricted Payments made by the Company and its Restricted Subsidiaries after
the date of this Indenture (excluding Restricted Payments permitted by clauses
(2), (3), (5) and (6) of the next succeeding paragraph), is less than the sum of
(i) the dollar amount calculated as of March 9, 2005 under Section 4.07(c) of
that certain Indenture dated July 21, 2003 among the Company, the Subsidiary
Guarantors and J.P. Morgan Trust Company, National Association as successor
trustee to Bank One, National Association, plus (ii) 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 prior to the date of this
Indenture to the end of the Company's most recently ended fiscal quarter for
which internal financial statements are available at the time of such Restricted
Payment (or, if such Consolidated Net Income for such period is a deficit, less
100% of such deficit), plus (iii) 100% of the aggregate net cash proceeds
received by the Company from the issue and sale since the date of this Indenture
of Equity Interests in the Company or of debt securities of the Company that
have been converted into or exchanged for such Equity Interests (other than
Equity Interests (or convertible debt securities) sold to a Subsidiary of the
Company and other than Disqualified Stock or debt securities that have been
converted into Disqualified Stock), plus (iv) to the extent that any Restricted
Investment that was made after the date of this Indenture is sold for cash or
otherwise liquidated or repaid for cash, the lesser of (A) the net proceeds of
such sale, liquidation or repayment and (B) the initial amount of such
Restricted Investment.

      The foregoing provisions shall not prohibit (1) the payment of any
dividend within 60 days after the date of declaration thereof, if at said date
of declaration such payment would have complied with the provisions of this
Indenture; (2) the redemption, repurchase, retirement or other acquisition of
any Equity Interests of the Company in exchange for, or out of the proceeds of,
the substantially concurrent sale (other than to a Subsidiary of the Company) of
other Equity Interests of the Company (other than any Disqualified Stock);
provided that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition shall be excluded
from clause (c) (ii) of the preceding paragraph; (3) the defeasance, redemption
or repurchase of Subordinated Indebtedness with the net cash proceeds from an
incurrence of subordinated Permitted Refinancing Debt or the substantially
concurrent sale (other than to a Subsidiary of the Company) of Equity Interests
of the Company (other than Disqualified Stock); provided that the amount of any
such net cash proceeds that are utilized for any such redemption, repurchase,
retirement or other acquisition shall be excluded from clause (c) (ii) of the
preceding paragraph; (4) the repurchase, redemption or other acquisition or


                                       38
<PAGE>
retirement for value of any Equity Interests of the Company or any Subsidiary of
the Company held by any of the Company's (or any of its Subsidiaries') employees
pursuant to any management equity subscription agreement or stock option
agreement in effect as of the date of this Indenture; provided that the
aggregate price paid for all such repurchased, redeemed, acquired or retired
Equity Interests shall not exceed $2.0 million in any twelve-month period; and
provided further that no Default or Event of Default shall have occurred and be
continuing immediately after such transaction; (5) repurchases of Equity
Interests deemed to occur upon exercise of stock options if such Equity
Interests represent a portion of the exercise price of such options; and (6)
cash payments made by the Company for the repurchase, redemption or other
acquisition or retirement of the Company's 7 3/8% Senior Subordinated Notes due
2013.

      The amount of all Restricted Payments (other than cash) shall be the fair
market value (as determined in good faith by a resolution of the Board of
Directors of the Company set forth in an Officers' Certificate delivered to the
Trustee, which determination shall be conclusive evidence of compliance with
this provision) on the date of the Restricted Payment of the asset(s) proposed
to be transferred by the Company or the applicable Restricted Subsidiary, as the
case may be, pursuant to the Restricted Payment. Not later than five days after
the date of making any Restricted Payment, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

      In computing Consolidated Net Income for purposes of this Section 4.07,
(i) the Company shall use audited financial statements for the portion of the
relevant period for which audited financial statements are available on the date
of determination and unaudited financial statements and other current financial
data based on the books and records of the Company for the remaining portion of
such period and (ii) the Company shall be permitted to rely in good faith on the
financial statements and other financial data derived from the books and records
of the Company that are available on the date of determination. If the Company
makes a Restricted Payment which, at the time of the making of such Restricted
Payment, would on the good faith determination of the Company be permitted under
the requirements of this Indenture, such Restricted Payment shall be deemed to
have been made in compliance with this Indenture notwithstanding any subsequent
adjustments made in good faith to the Company's financial statements affecting
Consolidated Net Income of the Company for any period.

      The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default. For
purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash) in
the Subsidiary so designated shall be deemed to be Restricted Payments at the
time of such designation and shall reduce the amount available for Restricted
Payments under clause (c) of the first paragraph of this covenant. All such
outstanding Investments shall be deemed to constitute Investments in an amount
equal to the greater of the fair market value or the book value of such
Investments at the time of such designation. Such designation shall only be
permitted if such Restricted Payment would be permitted at such time and if such
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary.

      Section 4.08. Dividend and Other Payment Restrictions Affecting
Subsidiaries.

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i) (x) pay dividends or make any other distributions
to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or
(2) with respect to any other interest or participation in, or measured by, its
profits, or (y) pay any indebtedness owed by it to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Company or any of
its Restricted Subsidiaries or (iii) transfer any of its properties or assets to
the Company or any of its Restricted Subsidiaries, except for such encumbrances
or restrictions existing under or by reason of (a) the Credit Agreement as in
effect as of the date of this Indenture, and any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings thereof or any other Credit Facility, provided that such
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements, refinancings or any other Credit Facilities are no
more restrictive taken as a whole with respect to such dividend and other
payment restrictions than those contained in the Credit Agreement as in effect
on the date of this Indenture, (b) this Indenture and the Notes, (c) applicable
law, (d) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at
the time of such acquisition (except, in the case of Indebtedness, to the extent
such Indebtedness was incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person, other than the Person and its
Subsidiaries, or the property or assets of the Person and its Subsidiaries, so
acquired, provided that, in the case of Indebtedness, such Indebtedness was
permitted by the terms of this Indenture to be incurred, (e) by reason of
customary non-assignment provisions in leases and customary provisions in other
agreements that restrict assignment of such agreements or rights thereunder,
entered into in the ordinary course of business and consistent with past
practices, (f) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause
(iii) above on the property so acquired or (g) Permitted Refinancing Debt,
provided that the restrictions contained in the agreements governing such
Permitted Refinancing Debt are no more restrictive than those contained in the
agreements governing the Indebtedness being refinanced.

      Section 4.09. Incurrence of Indebtedness and Issuance of Disqualified
Stock.

      The Company shall not, and shall not permit any of its 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 shall not issue any Disqualified Stock and shall 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 shares of Disqualified Stock if:

            (i) the Fixed Charge Coverage Ratio for the Company's most recently
      ended four full fiscal quarters for which internal financial statements
      are available immediately preceding the date on which such additional
      Indebtedness is incurred or such Disqualified


                                       40
<PAGE>
      Stock is issued would have been at least 2.5 to 1, determined on a pro
      forma basis as set forth in the definition of Fixed Charge Coverage Ratio;
      and

            (ii) no Default or Event of Default shall have occurred and be
      continuing at the time such additional Indebtedness is incurred or such
      Disqualified Stock is issued or would occur as a consequence of the
      incurrence of the additional Indebtedness or the issuance of the
      Disqualified Stock.

      Notwithstanding the foregoing, this Indenture shall not prohibit any of
the following (collectively, "Permitted Indebtedness"): (a) the Indebtedness
evidenced by the Notes; (b) the Indebtedness evidenced by the 7 3/8% Senior
Subordinated Notes; (c) the incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness pursuant to Credit Facilities, so long as the
aggregate principal amount of all Indebtedness outstanding under all Credit
Facilities does not, at any one time, exceed the greater of (1) $600.0 million
(or, if there is any permanent reduction in the aggregate principal amount
permitted to be borrowed under the Credit Agreement, such lesser aggregate
principal amount) and (2) an amount equal to the sum of (x) $50 million plus (y)
30% of Adjusted Consolidated Net Tangible Assets determined after the incurrence
of such Indebtedness (including the application of the proceeds therefrom), (d)
the guarantee by any Subsidiary Guarantor of any Indebtedness that is permitted
by this Indenture to be incurred by the Company; (e) all Indebtedness of the
Company and its Restricted Subsidiaries in existence as of the date of this
Indenture; (f) intercompany Indebtedness between or among the Company and any of
its Wholly Owned Restricted Subsidiaries; provided, however, that (1) if the
Company is the obligor on such Indebtedness, such Indebtedness is expressly
subordinate to the payment in full of all Obligations with respect to the Notes
and (2) (A) 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
Wholly Owned Restricted Subsidiary and (B) any sale or other transfer of any
such Indebtedness to a Person that is not either the Company or a Wholly Owned
Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence
of such Indebtedness by the Company or such Restricted Subsidiary, as the case
may be; (g) Indebtedness in connection with one or more standby letters of
credit, guarantees, performance bonds or other reimbursement obligations, in
each case, issued in the ordinary course of business and not in connection with
the borrowing of money or the obtaining of advances or credit (other than
advances or credit on open account, includible in current liabilities, for goods
and services in the ordinary course of business and on terms and conditions
which are customary in the Oil and Gas Business, and other than the extension of
credit represented by such letter of credit guarantee or performance bond
itself), not to exceed in the aggregate at any given time 5.0% of Total Assets;
(h) Indebtedness under Interest Rate Hedging Agreements entered into for the
purpose of limiting interest rate risks, provided that the obligations under
such agreements are related to payment obligations on Indebtedness otherwise
permitted by the terms of this covenant and that the aggregate notional
principal amount of such agreements does not exceed 105% of the principal amount
of the Indebtedness to which such agreements relate; (i) Indebtedness under Oil
and Gas Hedging Contracts, provided that such contracts were entered into in the
ordinary course of business for the purpose of limiting risks that arise in the
ordinary course of business of the Company and its Restricted Subsidiaries; (j)
the incurrence by the Company of Indebtedness not otherwise permitted to be
incurred pursuant to this paragraph, provided that the aggregate principal
amount (or accreted value, as applicable) of all Indebtedness incurred pursuant
to this clause (i), together with all Permitted Refinancing Debt incurred
pursuant to clause (k) of this


                                       41
<PAGE>
paragraph in respect of Indebtedness previously incurred pursuant to this clause
(i), does not exceed $10.0 million at any one time outstanding; (k) Permitted
Refinancing Debt incurred in exchange for, or the net proceeds of which are used
to refinance, extend, renew, replace, defease or refund, Indebtedness that was
permitted by this Indenture to be incurred (including Indebtedness previously
incurred pursuant to this clause (k)); (l) accounts payable or other obligations
of the Company or any Restricted Subsidiary to trade creditors created or
assumed by the Company or such Restricted Subsidiary in the ordinary course of
business in connection with the obtaining of goods or services; (m) Indebtedness
consisting of obligations in respect of purchase price adjustments, guarantees
or indemnities in connection with the acquisition or disposition of assets; and
(n) production imbalances that do not, at any one time outstanding, exceed 2% of
the Total Assets of the Company.

      The Company shall not permit any of its Unrestricted Subsidiary to incur
any Indebtedness other than Non-Recourse Debt; provided, however, if any such
Indebtedness ceases to be Non-Recourse Debt, such event shall be deemed to
constitute an incurrence of Indebtedness by the Company.

      Section 4.10. Asset Sales.

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in an Asset Sale unless (i) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value (as determined in good
faith by a resolution of the Board of Directors of the Company set forth in an
Officer's Certificate delivered to the Trustee, which determination shall be
conclusive evidence of compliance with this provision) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 85% of the
consideration therefor received by the Company or such Restricted Subsidiary in
such Asset Sale, plus all other Asset Sales since the date of this Indenture, on
a cumulative basis, is in the form of cash or Cash Equivalents; provided that
the amount of any liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet), of the Company or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any guarantee thereof) 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.

      Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option: (a) to reduce Senior
Debt, (b) to acquire controlling interests in another Oil and Gas Business, (c)
to make capital expenditures in respect of the Company's or its Restricted
Subsidiaries' Oil and Gas Business, (d) to purchase long-term assets that are
used or useful in such Oil and Gas Business or (e) to repurchase any Notes.
Pending the final application of any such Net Proceeds, the Company may
temporarily reduce Senior Debt that is revolving debt or otherwise invest such
Net Proceeds in any manner that is not prohibited by this Indenture. Any Net
Proceeds from Asset Sales that are not applied as provided in the first sentence
of this paragraph shall (after the expiration of the periods specified in this
paragraph) be deemed to constitute "Excess Proceeds."

      When the aggregate amount of Excess Proceeds exceeds $10.0 million, the
Company shall make an Asset Sale Offer to purchase the maximum principal amount
of Notes and any


                                       42
<PAGE>
other pari passu Indebtedness to which the Asset Sale Offer applies that may be
purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to, in the case of the Notes, 100% of the principal amount thereof plus
accrued and unpaid interest thereon to the date of purchase or, in the case of
any other pari passu Indebtedness, 100% of the principal amount thereof (or with
respect to discount pari passu Indebtedness, the accreted value thereof) on the
date of purchase, in each case, in accordance with the procedures set forth in
Section 3.09 hereof or the agreements governing pari passu Indebtedness, as
applicable. To the extent that the aggregate principal amount (or accreted
value, as the case may be) of the Notes and pari passu Indebtedness tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company
may use any remaining Excess Proceeds for general corporate purposes. If the sum
of (i) the aggregate principal amount of Notes surrendered by Holders thereof,
and (ii) the aggregate principal amount or accreted value, as the case may be,
of other pari passu Indebtedness surrendered by holders or lenders thereof,
exceeds the amount of Excess Proceeds, the Trustee and the trustee or other
lender representatives for the pari passu Indebtedness shall select the Notes
and other pari passu Indebtedness to be purchased on a pro rata basis, based on
the aggregate principal amount (or accreted value, as applicable) thereof
surrendered in such Asset Sale Offer. Upon completion of such Asset Sale Offer,
the Excess Proceeds shall be reset at zero.

      Section 4.11. Transactions with Affiliates.

      The Company shall not, and shall not permit any of its Subsidiaries to,
make any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any of its Affiliates (each of the
foregoing, an "Affiliate Transaction"), unless (i) such Affiliate Transaction is
on terms that are no less favorable to the Company or the relevant Subsidiary
than those that would have been obtained in a comparable transaction by the
Company or such Subsidiary with an unrelated Person and (ii) the Company
delivers to the Trustee (a) with respect to an Affiliate Transaction or series
of related Affiliate Transactions involving aggregate consideration in excess of
$1,000,000 but less than or equal to $5,000,000, an Officers' Certificate to the
Trustee certifying that such Affiliate Transaction complies with clause (i)
above, (b) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $5,000,000
but less than or equal to $10,000,000, a resolution of the Board of Directors
set forth in an Officer's Certificate certifying that such Affiliate Transaction
or series of related Affiliate Transactions complies with clause (i) above and
that such Affiliate Transaction or series of related Affiliate Transactions has
been approved in good faith by a majority of the members of the Board of
Directors of the Company who are disinterested with respect to such Affiliate
Transaction or series of related Affiliate Transactions (which resolution shall
be conclusive evidence of compliance with this provision) and (c) with respect
to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $10,000,000, a resolution of the
Board of Directors set forth in an Officers' Certificate certifying that such
Affiliate Transaction or series of related Affiliate Transactions complies with
clause (i) above and that such Affiliate Transaction or series of related
Affiliate Transactions has been approved in good faith by a resolution adopted
by a majority of the members of the Board of Directors of the Company who are
disinterested with respect to such Affiliate Transaction or series of related
Affiliate Transactions and an opinion as to the fairness to the Company or such

                                       43
<PAGE>
Subsidiary of such Affiliate Transaction or series of related Affiliate
Transactions from a financial point of view issued by an accounting, appraisal,
engineering or investment banking firm of national standing (which resolution
and fairness opinion shall be conclusive evidence of compliance with this
provision); provided, however, that the foregoing shall not apply to (l)
transactions contemplated by any employment agreement or other compensation plan
or arrangement entered into by the Company or any of its Subsidiaries in the
ordinary course of business and consistent with the past practice of the Company
or such Subsidiary, (2) transactions between or among the Company and/or its
Restricted Subsidiaries, (3) Permitted Investments and Restricted Payments that
are permitted by Section 4.07 hereof, and (4) any indemnification payment made
to any director, officer or employee of the Company or any Subsidiary pursuant
to charter, bylaw, statutory or contractual provisions.

      Section 4.12. Liens.

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien securing Indebtedness of any kind (other than
Permitted Liens) upon any of its property or assets, now owned or hereafter
acquired, unless all payments under the Notes are secured by such Lien prior to,
or on an equal and ratable basis with, the Indebtedness so secured for so long
as such Indebtedness is secured by such Lien.

      Section 4.13. Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, each Holder of the Notes shall
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of such Holder's Notes pursuant to the
offer described below (the "Change of Control Offer") at an offer price in cash
equal to 101% of the aggregate principal amount of the Notes plus accrued and
unpaid interest if any, thereon to the date of purchase (the "Change of Control
Payment"). Within 30 days following any Change of Control, the Company shall
mail a notice to each Holder stating: (1) a description of the transaction or
transactions that constitute the Change of Control; (2) that the Change of
Control Offer is being made pursuant to this Section 4.13 and that all Notes
tendered shall be accepted for payment; (3) the purchase price and the purchase
date described below (the "Change of Control Payment Date"); (4) that any Note
not tendered shall continue to accrue interest, if any; (5) that, unless the
Company defaults in the payment of the Change of Control Payment, all Notes

business on the third Business Day preceding the Change of Control Payment Date;
(7) that Holders shall be entitled to withdraw their election if the Paying

thereof. The Company and each Subsidiary Guarantor shall comply with the
requirements of Rule l4e-1 under the Exchange Act and any other securities laws

tendered and not withdrawn under such Change of Control Offer.

      Section 4.14. Additional Subsidiary Guarantees.

      In the event that the Company or any of its Subsidiaries shall acquire or
create a Restricted Subsidiary after the date of this Indenture, such newly
acquired or created Restricted Subsidiary shall be deemed to make the guarantee
set forth in Section 11.01 and the Company shall cause such Subsidiary to
evidence such guarantee in the manner set forth in Section 11.02; provided that,
in no event shall any non-U.S. Subsidiary of the Company be deemed to make such

existence of each of the 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 (ii) the rights (charter, partnership
agreement and


                                       45
<PAGE>
statutory), licenses and franchises of the Company and the Subsidiaries;
provided, however, that the Company and the Subsidiaries shall not be required
to preserve any such right, license or franchise, or the corporate, partnership
or other existence of any of the Subsidiaries, if the Board of Directors of the
relevant Person shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and the Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Notes.

      Section 4.16. No Senior Subordinated Debt.

      Notwithstanding the provisions of Section 4.09 hereof, (i) the Company
shall not incur, create, issue, assume, guarantee or otherwise become liable for

create, issue, assume, guarantee or otherwise become liable for any Indebtedness
that is subordinate or junior in right of payment to Senior Debt of the Company

however, that the foregoing limitations shall not apply to distinctions between
categories of Indebtedness that exist by reason of any Liens arising or created

      Section 4.17. Business Activities.

      The Company shall not, and shall not permit any Restricted Subsidiary to,
engage in any material respect in any business other than the Oil and Gas

      Section 5.01. Merger, Consolidation, or Sale of Substantially All Assets.

the Company is the surviving corporation), or sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of its properties or
assets, in one or more related transactions, to another Person, and the Company
may not permit any of its Restricted Subsidiaries to enter into any such
transaction or series of transactions if such transaction or series of
transactions would, in the aggregate, result in a sale, assignment, transfer,
lease, conveyance, or other disposition of all or substantially all of the
properties or assets of the Company to another Person, in either case unless (i)
the Company is the surviving corporation or the Person formed by or surviving
any such consolidation or merger (if other than the Company) or to which such
sale, assignment, transfer, lease, conveyance or other disposition shall have
been made (the "Surviving Entity") is a corporation organized or existing under
the laws of the United States, any state thereof or the District of Columbia;
(ii) the Surviving Entity (if the Company is not the continuing obligor under
this Indenture) assumes all the obligations of the Company under any
Registration Rights Agreement, the Notes and this Indenture pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee; (iii)
immediately before and after giving effect to such transaction or series of
transactions no Default or Event of Default exists; (iv) immediately after
giving effect to such transaction or series of transactions on a pro forma basis
(and treating any


                                       46
<PAGE>
Indebtedness not previously an obligation of the Company or any of its
Subsidiary which becomes the obligation of the Company or any of its Subsidiary
as a result of such transaction or series of transactions as having been
incurred at the time of such transaction or series of transactions), the
Consolidated Net Worth of the Company and its Subsidiaries or the Surviving
Entity (if the Company is not the continuing obligor under this Indenture) is
equal to of greater than the Consolidated Net Worth of the Company and its
Subsidiaries immediately prior to such transaction or series of transactions and
(v) the Company or Surviving Entity (if the Company is not the continuing

series of transactions had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the test set forth in the first paragraph of Section
4.09 hereof. Notwithstanding the foregoing clauses (iv) and (v), any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to the Company, and any Wholly Owned Restricted Subsidiary
may consolidate with, merge into or transfer all or part of its properties and

      Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company in accordance with Section 5.01 hereof, the Surviving Entity
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 Surviving Entity 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 that meets the requirements of Section 5.01 hereof.

                                    ARTICLE 6
                              DEFAULTS AND REMEDIES

      Section 6.01. Events of Default.

      An "Event of Default" occurs if:

            (1) the Company defaults in the payment of interest (including any
      interest payable as Liquidated Damages), if any, on the Notes when the
      same becomes due and payable and the Default continues for a period of 30
      days, whether or not such payment is prohibited by the provisions of
      Article 10 hereof;

            (2) the Company defaults in the payment of the principal of or
      premium, if any, on the Notes, whether or not such payment is prohibited
      by the provisions of Article 10 hereof;


                                       47
<PAGE>
            (3) the Company fails to observe or perform any covenant, condition
      or agreement on the part of the Company to be observed or performed
      pursuant to Article 5 hereof;

            (4) the Company fails to observe or perform any covenant, condition
      or agreement on the part of the Company to be observed or performed
      pursuant to Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14,
      4.16 and 4.17 hereof and the Default continues for the period and after
      the notice specified below;

            (5) the Company fails to comply with any of its other agreements or
      covenants in, or provisions of, the Notes or this Indenture and the
      Default continues for consecutive days after the notice specified below;

            (6) except as permitted herein, any Guarantee shall be held in any
      judicial proceeding to be unenforceable or invalid or shall cease for any
      reason to be in full force and effect or a Subsidiary Guarantor, or any
      Person acting on behalf of a Subsidiary Guarantor, shall deny or disaffirm
      such Subsidiary Guarantor's obligation under its Guarantee;

            (7) a default occurs under any mortgage, indenture or instrument
      under which there may be issued or by which there may be secured or
      evidenced any Indebtedness for money borrowed by the Company or any of its
      Restricted Subsidiaries (or the payment of which is guaranteed by the
      Company or any of its Restricted Subsidiaries), whether such Indebtedness
      or guarantee now exists or shall be created hereafter, which default (a)
      is caused by a failure to pay principal of or premium, if any, or interest
      on such Indebtedness prior to the expiration of the grace period provided
      in such Indebtedness on the date of such default (a "Payment Default") or
      (b) results in the acceleration of such Indebtedness prior to its express
      maturity and, in each case, the principal amount of any such Indebtedness,
      together with the principal amount of any other such Indebtedness under
      which there is then existing a Payment Default or the maturity of which
      has been so accelerated, aggregates $10 million or more; provided, that if
      any such default is cured or waived or any such acceleration rescinded, or
      such Indebtedness is repaid, within a period of 10 days from the
      continuation of such default beyond the applicable grace period or the
      occurrence of such acceleration, as the case may be, such Event of Default
      under this Indenture and any consequential acceleration of the Notes shall
      be automatically rescinded;

            (8) a final non-appealable judgment or order or final non-appealable
      judgments or orders are rendered against the Company or any Restricted
      Subsidiary that remain unpaid or discharged for a period of 60 days and
      that require the payment of money, either individually or in an aggregate
      amount, in excess of $10 million;

            (9) the Company or any Significant Subsidiary or any group of
      Subsidiaries that, taken together, would constitute a Significant
      Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

               (a) a commences a voluntary case or proceeding,


                                       48
<PAGE>
               (b) consents to the entry of an order for relief against it in an
         involuntary case or proceeding,

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

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

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

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

               (b) appoints a Custodian of the Company, any Significant
         Subsidiary or any group of Subsidiaries that, taken together, would
         constitute a Significant Subsidiary, or for all or substantially all of
         the property of the Company, any Significant Subsidiary or any group of
         Subsidiaries that, taken together, would constitute a Significant
         Subsidiary, or

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

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

      The term "Custodian" means any receiver, trustee, assignee, liquidator or
similar official under any Bankruptcy Law.

      A Default under clause (4) is not an Event of Default until the Trustee
notifies the Company, or the Holders of at least 25% in principal amount of the
then outstanding Notes notify the Company and the Trustee, of the Default and
the Company does not cure the Default within 30 consecutive days after receipt
of the notice. A Default under clause (5) is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the then outstanding Notes notify the Company and the Trustee, of the Default
and the Company does not cure the Default within 60 days after receipt of the
notice. The notice must specify the Default, demand that it be remedied and
state that the notice is a "Notice of Default."

      Section 6.02.  Acceleration.

      If an Event of Default (other than an Event of Default specified in
clauses (9) and (10) of Section 6.01 hereof) relating to the Company or any
Subsidiary Guarantor occurs and is continuing, the Trustee by notice to the
Company, or the Holders of at least 25% in principal amount of the then
outstanding Notes by written notice to the Company and the Trustee, may declare
the unpaid principal amount of and any accrued and unpaid interest on all the
Notes to be due and payable immediately. If payment of the Notes is accelerated
because of an Event of Default, the Company or the Trustee shall notify the
holders of Designated Senior Debt of such


                                       49
<PAGE>
acceleration. Upon such declaration the principal and interest shall be due and
payable immediately; provided, however, that so long as any Designated Senior
Debt or any commitment therefor is outstanding, any such notice or declaration
shall not become effective until the earlier of (a) five Business Days after
such notice is delivered to the representative for the Designated Senior Debt or
(b) the acceleration of any Designated Senior Debt and thereafter, payments on
the Notes pursuant to this Article 6 shall be made only to the extent permitted
pursuant to Article 10 herein. Notwithstanding the foregoing, if any Event of
Default specified in clause (9) or (10) of Section 6.01 hereof relating to the
Company, any Significant Subsidiary or any group of Subsidiaries that, taken
together, would constitute a Significant Subsidiary occurs, such an amount shall
ipso facto become and be immediately due and payable without any declaration or
other act or notice on the part of the Trustee or any Holder.

      After a declaration of acceleration under this Indenture, but before a
judgment or decree for payment of principal, premium, if any, and interest on
the Notes due under this Article 6 has been obtained by the Trustee, Holders of
a majority in principal amount of the then outstanding Notes by written notice
to the Company and the Trustee may rescind an acceleration and its consequences
if (i) the Company or any Subsidiary Guarantor has paid or deposited with the
Trustee a sum sufficient to pay (a) all sums paid or advanced by the Trustee
under this Indenture and the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and (b) all overdue interest
on the Notes, if any, (ii) the rescission would not conflict with any judgment
or decree of a court of competent jurisdiction and (iii) all existing Events of
Default (except nonpayment of principal, premium, if any, or interest that has
become due solely because of the acceleration) have been cured or waived.

      Section 6.03.  Other Remedies.

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

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

      Section 6.04.  Waiver of Past Defaults.

      Holders of not less than a majority in aggregate principal amount of the
Notes then outstanding by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of 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


                                       50
<PAGE>
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

      Section 6.05.  Control by Majority.

      Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability it being understood that (subject to Section 7.01)
the Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such holders.

      Section 6.06.  Limitation on Suits.

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

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

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

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

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

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

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

      Section 6.07.  Rights of Holders of Notes to Receive Payment.

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

      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


                                       51
<PAGE>
against the Company or any Subsidiary Guarantor for the whole amount of
principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

      Section 6.09.  Trustee May File Proofs of Claim.

      The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
or any of the Subsidiary Guarantors (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and may be a member of the
creditors' committee.

      Section 6.10.  Priorities.

      If the Trustee collects any money pursuant to this Article, it shall,
subject to the provisions of Article 10, pay out the money in the following
order:

      First: to the Trustee, its agents and attorneys for amounts due
under Sections 6.08 and 7.07 hereof, including payment of all
compensation, expense and liabilities incurred, and all advances made, by
the Trustee and the costs and expenses of collection;

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


                                       52
<PAGE>
      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 does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.



                                    Article 7
                                     TRUSTEE

      Section 7.01.  Duties of Trustee.

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

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

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

               (ii) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness

Guarantors of their obligations hereunder. The Company and the Subsidiary
Guarantors shall defend the claim and the Trustee shall cooperate in the
defense. The Trustee may have separate counsel and the Company and the

and upon receipt by the Trustee of the documents described in Section 7.02
hereof, the Trustee shall join with the Company and the Subsidiary 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 shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

      Section 9.02.  With Consent of Holders of Notes.

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

      Notwithstanding the foregoing, without the consent of at least 66 2/3% in
aggregate principal amount of the Notes then outstanding (including consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, Notes), no waiver or amendment to this Indenture may make any change in the
provisions of Sections 3.09, 4.10 and 4.13 hereof that adversely affect the
rights of any Holder of Notes. In addition, any amendment to the provisions of
Article 10 of this Indenture shall require the consent of the Holders of at
least 66 2/3% in aggregate principal amount of the Notes then outstanding if
such amendment would adversely affect the rights of Holders of Notes; provided
that, no amendment may be made to the provisions of Article 10 of this Indenture
that adversely affects the rights of any holder of Senior Debt then outstanding
unless the holders of such Senior Debt (or any group or representative thereof
authorized to consent) consent to such change.

      Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in
aggregate principal amount of the Notes then outstanding may waive compliance in
a particular instance by the


                                       63
<PAGE>
Company or any Subsidiary Guarantor with any provision of this Indenture, the
Notes or the Guarantees. However, without the consent of each Holder affected,
an amendment or waiver may not (with respect to any Notes held by a
non-consenting Holder):

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

        (b) reduce the principal of or change the fixed maturity of any Note or
alter the provisions with respect to the redemption of the Notes (except as
provided above with respect to Sections 3.09, 4.10 and 4.13 hereof);

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

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

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

        (f) 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 or premium, if any, or interest on the Notes; or

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

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

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

      After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
indenture or waiver.

      Section 9.03.  Compliance with Trust Indenture Act.

      Every amendment or supplement to this Indenture or the Notes shall 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 authenticate new Notes
that reflect the amendment, supplement or waiver.

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

      Section 9.06.  Trustee to Sign Amendment, etc.

      The Trustee shall sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. Neither the
Company nor any Subsidiary Guarantor may sign an amendment or supplemental
Indenture until its respective Board of Directors approves it. In executing any
amended or supplemental indenture, the Trustee shall be entitled to receive and
(subject to Section 7.01) shall be fully protected in relying upon, an Officer's
Certificate and an Opinion of Counsel stating that the execution of such amended
or supplemental indenture is authorized or permitted by this Indenture and that
there has been compliance with all conditions precedent.



                                   Article 10
                                  SUBORDINATION

      Section 10.01.  Agreement to Subordinate.

      The Company and each Subsidiary Guarantor agree, and each Holder by
accepting a Note and the related Guarantee agrees, that (i) the Indebtedness
evidenced by (a) the Notes, including, but not limited to, the payment of
principal of, premium, if any, and interest on the Notes, and any other payment
Obligation of the Company in respect of the Notes (including any obligation to
repurchase the Notes) is subordinated in right of payment, to the extent and in
the manner


                                       65
<PAGE>
provided in this Article, to the prior payment in full in cash of all Senior
Debt of the Company (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and (b) the Guarantees and other
payment Obligations in respect of the Guarantees are subordinated in right of
payment, to the extent and in the manner provided in this Article, to the prior
payment in full in cash of all Senior Debt of each Subsidiary Guarantor and (ii)
the subordination is for the benefit of the Holders of Senior Debt.

interest is allowed as a claim in such proceeding), reimbursement obligations,
fees, commissions, expenses, indemnities or other amounts and (ii) any other

      Section 10.03.  Liquidation; Dissolution; Bankruptcy.

                 (1) the holders of Senior Debt of the Company shall be entitled
      to receive payment in full in cash of all Obligations in respect of such
      Senior Debt (including


                                       66
<PAGE>
      interest after the commencement of any such proceeding at the rate
      specified in the applicable Senior Debt, whether or not a claim for such
      interest would be allowed in such proceeding) before the Holders of Notes
      shall be entitled to receive any payment with respect to the Notes and
      related Obligations (except in each case that Holders of Notes may receive
      securities that are subordinated at least to the same extent as the Notes
      to Senior Debt and any securities issued in exchange for Senior Debt and
      payments made from any defeasance trust created pursuant to Section 8.01

                 (2) until all Obligations with respect to Senior Debt of the
      Company (as provided in subsection (1) above) are paid in full in cash,
      any payment or distribution to which the Holders of Notes and the related
      Guarantees would be entitled shall be made to holders of Senior Debt of
      the Company (except that Holders of Notes and the related Guarantees may
      receive securities that are subordinated at least to the same extent as
      the Notes to Senior Debt and any securities issued in exchange for Senior
      Debt and payments made from any defeasance trust created pursuant to
      Section 8.01 hereof provided that the, applicable deposit does not violate
      Article 8 or 10 of this Indenture).

        (b) Upon any payment or distribution of property or securities to
creditors of a Subsidiary Guarantor in a liquidation or dissolution of such
Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Subsidiary Guarantor or its
property, or in an assignment for the benefit of creditors or any marshalling of
such Subsidiary Guarantor's assets and liabilities:

                 (1) the holders of Senior Debt of such Subsidiary Guarantor
      shall be entitled to receive payment in full in cash of all Obligations in
      respect of such Senior Debt (including interest after the commencement of
      any such proceeding at the rate specified in the applicable Senior Debt,
      whether or not a claim for such interest would be allowed in such
      proceeding) before the Holders of Notes and the related Guarantees shall
      be entitled to receive any payment or distribution with respect to the
      Guarantee made by such Subsidiary Guarantor (except in each case that
      Holders of Notes and the related Guarantees may receive securities that
      are subordinated at least to the same extent as the Notes to Senior Debt
      and any securities issued in exchange for Senior Debt and payments made
      from any defeasance trust created pursuant to Section 8.01 hereof provided

      full in cash, any payment or distribution to which the Holders of Notes
      and the related Guarantees would be entitled shall be made to holders of
      Senior Debt of such Subsidiary Guarantor (except that Holders of Notes and
      the related Guarantees may receive securities that are subordinated at
      least to the same extent as the Notes to Senior Debt and any securities
      issued in exchange for Senior Debt and payments made from any defeasance
      trust created pursuant to Section 8.01 hereof provided that the applicable
      deposit does not violate Article 8 or 10 of this Indenture).


                                       67
<PAGE>
      Under the circumstances described in this Section 10.03, the Company, any
Subsidiary Guarantor or any receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar person making any payment or distribution of
cash or other property or securities is authorized or instructed to make any
payment or distribution to which the Holders of the Notes and the related
Guarantees would otherwise be entitled (other than securities that are
subordinated at least to the same extent as the Notes to Senior Debt and any
securities issued in exchange for Senior Debt and payments made from any
defeasance trust referred to in the second parenthetical clause of each of
clauses (a)(1), (b)(1), (a)(2) and (b)(2) above, which shall be delivered or
paid to the Holders of Notes as set forth in such clauses) directly to the
holders of the Senior Debt of the Company and any Subsidiary Guarantor, as
applicable, (pro rata to such holders on the basis of the respective amounts of
Senior Debt of the Company and any Subsidiary Guarantor, as applicable, held by
such holders) or their Representatives, or to any trustee or trustees under any
other indenture pursuant to which any such Senior Debt may have been issued, as
their respective interests appear, to the extent necessary to pay all such
Senior Debt in full, in cash or cash equivalents after giving effect to any
concurrent payment, distribution or provision thereof or to or for the holders
of such Senior Debt.

      To the extent any payment of or distribution in respect of Senior Debt
(whether by or on behalf of the Company or any Subsidiary Guarantor, as proceeds
of security or enforcement of any right of setoff or otherwise) is declared to
be fraudulent or preferential, set aside or required to be paid to any receiver,
trustee in bankruptcy, liquidating trustee, agent or other similar Person under
any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then if such payment or distribution is recovered by, or paid over to, such
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar
Person, the Senior Debt or part thereof originally intended to be satisfied
shall be deemed to be reinstated and outstanding as if such payment had not
occurred. To the extent the obligation to repay any Senior Debt is declared to
be fraudulent, invalid or otherwise set aside under any bankruptcy, insolvency,
receivership, fraudulent conveyance or similar law, then the obligation so
declared fraudulent, invalid or otherwise set aside (and all other amounts that
would come due with respect thereto had such obligation not been so affected)
shall be deemed to be reinstated and outstanding as Senior Debt for all purposes
hereof as if such declaration, invalidity or setting aside had not occurred.

      Section 10.04.  Default on Designated Senior Debt.

      The Company and the Subsidiary Guarantors may not make any payment
(whether by redemption, purchase, retirements, defeasance or otherwise) upon or
in respect of the Notes and the related Guarantees (other than securities that
are subordinated at least to the same extent as the Notes to Senior Debt and any
securities issued in exchange for Senior Debt and payments and other
distributions made from any defeasance trust created pursuant to Section 8.01
hereof if the applicable deposit does not violate Article 8 or 10 of this
Indenture) until all principal and other Obligations with respect to the Senior
Debt of the Company have been paid in full if:

               (i) a default in the payment of any principal of, premium, if
      any, or interest on Designated Senior Debt occurs; or

               (ii) any other default occurs and is continuing with respect to
      Designated Senior Debt that permits, or with the giving of notice or
      passage of time or both (unless


                                       68
<PAGE>
      cured or waived) would permit, holders of the Designated Senior Debt as to
      which such default relates to accelerate its maturity and the Trustee
      receives a notice of the default (a "Payment Blockage Notice") from the
      Company or the holders of any Designated Senior Debt. If the Trustee
      receives any such Payment Blockage Notice, no subsequent Payment Blockage
      Notice shall be effective for purposes of this Section unless and until
      360 days shall have elapsed since the date of commencement of the payment
      blockage period resulting from the immediately prior Payment Blockage
      Notice. No nonpayment default in respect of any Designated Senior Debt
      that existed or was continuing on the date of delivery of any Payment
      Blockage Notice to the Trustee shall be, or be made, the basis for a
      subsequent Payment Blockage Notice.

      The Company shall resume payments on and distributions in respect of the
Notes and any Subsidiary Guarantor shall resume making payments and
distributions pursuant to the Guarantees upon:

                 (1) in the case of a default referred to in Section
      10.04(i) hereof the date upon which the default is cured or waived,
      or

                 (2) in the case of a default referred to in Section 10.04(ii)
      hereof, the earliest of (1) the date on which such nonpayment default is
      cured or waived, (2) the date the applicable Payment Blockage Notice is
      retracted by written notice to the Trustee and (3) 90 days after the date
      on which the applicable Payment Blockage Notice is received unless (A) the
      maturity of any Designated Senior Debt has been accelerated or (B) a
      Default or Event of Default under Section 6.01(9) or (10) has occurred and
      is continuing,

if this Article otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

      Section 10.05.  Acceleration of Notes.

      If payment of the Notes is accelerated because of an Event of Default, the
Company shall promptly notify holders of Senior Debt of the acceleration.

      Section 10.06.  When Distribution Must be Paid Over.

      In the event that the Trustee or any Holder receives any payment or
distribution of or in respect of any Obligations with respect to the Notes or
the Guarantees at a time when such payment or distribution is prohibited by
Section 10.03 or Section 10.04 hereof, such payment or distribution shall be
held by the Trustee (if the Trustee has actual knowledge that such payment or
distribution is prohibited by Section 10.03 or Section 10.04) or such Holder, in
trust for the benefit of, and shall be paid forthwith over and delivered to, the
holders of Senior Debt as their interests may appear or their Representative
under the indenture or other agreement (if any) pursuant to which such Senior
Debt may have been issued, as their respective interests may appear, for
application to the payment of all Obligations with respect to Senior Debt
remaining unpaid to the extent necessary to pay such Obligations in full in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.


                                       69
<PAGE>
      With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 10, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and, except as provided in Section 10.12, shall not be
liable to any such holders if the Trustee shall pay over or distribute to or on
behalf of Holders of Notes or the Company, the Subsidiary Guarantors or any
other Person money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

      Section 10.07.  Notice by Company.

      The Company and the Subsidiary Guarantors shall promptly notify the
Trustee and the Paying Agent of any facts known to the Company or any Subsidiary
Guarantor that would cause a payment of any Obligations with respect to the
Notes or the related Guarantees to violate this Article, but failure to give
such notice shall not affect the subordination of the Notes and the related
Guarantees to the Senior Debt as provided in this Article.

      Section 10.08.  Subrogation.

      After all Senior Debt is paid in full and until the Notes are paid in
full, Holders of Notes and the related Guarantees shall be subrogated (equally
and ratably with all other Indebtedness pari passu with the Notes and the
Guarantees) to the rights of holders of Senior Debt to receive distributions and
payments applicable to Senior Debt to the extent that distributions and payments
otherwise payable to the Holders of Notes and the related Guarantees have been
applied to the payment of Senior Debt. A payment or distribution made under this
Article to holders of Senior Debt that otherwise would have been made to Holders
of Notes and the related Guarantees is not, as between the Company and Holders
of Notes, a payment by the Company on the Notes.

      Section 10.09.  Relative Rights.

      This Article defines the relative rights of Holders of Notes and the
related Guarantees and holders of Senior Debt. Nothing in this Indenture shall:

                 (1) impair, as between the Company and Holders of Notes, the
      obligation of the Company, which is absolute and unconditional, to pay
      principal of and interest on the Notes in accordance with their terms;

                 (2) affect the relative rights of Holders of Notes and the
      related Guarantees and creditors of the Company other than their rights in
      relation to holders of Senior Debt; or

                 (3) prevent the Trustee or any Holder from exercising its
      available remedies upon a Default or Event of Default, subject to the
      rights of holders and owners of Senior Debt to receive distributions and
      payments otherwise payable to Holders of Notes and the related Guarantees.


                                       70
<PAGE>
      If the Company fails because of this Article to pay principal of or
interest on a Note on the due date, the failure is still a Default or Event of
Default.

      Section 10.10.  Subordination May Not be Impaired by Company or the
Subsidiary Guarantors.

      No right of any present or future holders of any Senior Debt to enforce
subordination as provided in this Article 10 will at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or any Subsidiary Guarantor or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company or any Subsidiary
Guarantor with the terms of this Indenture, regardless of any knowledge thereof
that any such holder of Senior Debt may have or otherwise be charged with. The
provisions of this Article Ten are intended to be for the benefit of, and shall
be enforceable directly by, the holders of Senior Debt.

      Section 10.11.  Payment, Distribution or Notice to Representative.

      Whenever a payment or distribution is to be made or a notice given to
holders of Senior Debt, the distribution may be made and the notice given to
their Representative.

      Upon any payment or distribution of assets or securities of the Company or
any Subsidiary Guarantor referred to in this Article 10, the Trustee and the
Holders of Notes and the related Guarantees shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction or upon any
certificate of such Representative or of the liquidating trustee or agent or
other Person making any payment or distribution to the Trustee or to the Holders
of Notes and the related Guarantees for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of the
Senior Debt and other Indebtedness of the Company or any Subsidiary Guarantor,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 10.

      Section 10.12.  Rights of Trustee and Paying Agent.

      Notwithstanding the provisions of this Article 10 or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes and the Guarantees, unless the Trustee shall have
received at its Corporate Trust Office at least one Business Day prior to the
date of such payment written notice of facts that would cause the payment of any
Obligations with respect to the Notes or Guarantees to violate this Article,
which notice shall specifically refer to Section 10.03 or 10.04 hereof. Only the
Company or a Representative may give the notice. Nothing in this Article 10
shall impair the claims of, or payments to, the Trustee under or pursuant to
Section 7.07 hereof.

      The Trustee in its individual or any other capacity may hold Senior Debt
with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights.


                                       71
<PAGE>
      Section 10.13.  Authorization to Effect Subordination.

      Each Holder by the Holder's acceptance thereof authorizes and directs the
Trustee on the Holder's behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article 10, and
appoints the Trustee to act as the Holder's attorney-in-fact for any and all
such purposes. If the Trustee does not file a proper proof of claim or proof of
debt in the form required in any proceeding referred to in Section 6.09 hereof
at least 30 days before the expiration of the time to file such claim, each
lender under the Credit Agreement is hereby authorized to file an appropriate
claim for and on behalf of the Holders of the Notes and the related Guarantees.

      Section 10.14.  Amendments.

      No amendment may be made to the provisions of or the definitions of any
terms appearing in this Article 10, or to the provisions of Section 6.02
relating to the Designated Senior Debt, that adversely affects the rights of any
holder of Senior Debt then outstanding unless the holders of such Senior Debt
(or any group or Representative authorized to give a consent) consent to such
change.

      Section 10.15.  No Waiver of Subordination Provisions.

      Without in any way limiting the generality of Section 10.09 of this
Indenture, the holders of Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article 10 or the obligations hereunder of the
Holders to the holders of Senior Debt, do any one or more of the following: (a)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, Senior Debt or any instrument evidencing the same or any
agreement under which Senior Debt is outstanding or secured; (b) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Debt; (c) release any Person liable in any manner for the
collection of Senior Debt; and (d) exercise or refrain from exercising any
rights against the Company and each Subsidiary Guarantor and any other Person.



                                   Article 11
                                 THE GUARANTEES

      Section 11.01.  The Guarantees.

      Each of the Subsidiary Guarantors hereby, jointly and severally,
unconditionally guarantees to each Holder of a Note authenticated and delivered
by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of this Indenture, the Notes or the
obligations of the Company hereunder or thereunder, that: (a) the principal of
and premium and interest, on the Notes shall be promptly paid in full when due,
whether at maturity, by acceleration, redemption or otherwise, and interest on
the overdue principal of and interest on premium and interest, on the Notes, if
any, if lawful, and all other obligations of the Company to the Holders or the
Trustee hereunder or thereunder shall be


                                       72
<PAGE>
promptly paid in full or performed, all in accordance with the terms hereof and
thereof; and (b) in case of any extension of time of payment or renewal of any
Notes or any of such other obligations, that the same shall be promptly paid in
full when due or performed in accordance with the terms of the extension or
renewal, whether at stated maturity, by acceleration or otherwise. Failing
payment when due of any amount so guaranteed or any performance so guaranteed
for whatever reason, the Subsidiary Guarantors shall be jointly and severally
obligated to pay the same immediately. The Subsidiary Guarantors hereby agree
that their obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
with respect to any provisions hereof or thereof, the recovery of any judgment
against the Company, any action to enforce the same or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. Each of the Subsidiary Guarantors hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest, notice and all demands whatsoever and covenant
that this Guarantee shall not be discharged except by complete performance of
the obligations contained in the Notes and this Indenture. If any Holder or the
Trustee is required by any court or otherwise to return to the Company or the
Subsidiary Guarantors, or any Custodian, Trustee, liquidator or other similar
official acting in relation to either the Company or the Subsidiary Guarantors,
any amount paid by either to the Trustee or such Holder, this Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect.
Each of the Subsidiary Guarantors agrees that it shall not be entitled to any
right of subrogation in relation to the Holders of Notes in respect of any
obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. Each of the Subsidiary Guarantors further agrees that, as
between the Subsidiary Guarantors, on the one hand, and the Holders and the
Trustee, on the other hand, (x) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article 6 for the purposes of this
Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations guaranteed hereby and (y) in the
event of any declaration of acceleration of such obligations as provided in
Article 6, such obligations (whether or not due and payable) shall forthwith
become due and payable by the Subsidiary Guarantors for the purpose of this
Guarantee. The Subsidiary Guarantors shall have the right to seek contribution
from any Subsidiary Guarantor not paying so long as the exercise of such right
does not impair the rights of the Holders under the Guarantees.

      Section 11.02.  Execution and Delivery of Guarantees.

      (i) To evidence its Guarantee set forth in Section 11.01, each of the
Subsidiary Guarantors hereby agrees that a notation of such Guarantee
substantially in the form of Exhibit C shall be endorsed by an officer of such
Subsidiary Guarantor on each Note authenticated and delivered by the Trustee,
that this Indenture shall be executed on behalf of such Subsidiary Guarantor by
its President or one of its Vice Presidents and attested to by an Officer and
that such Subsidiary Guarantor shall deliver to the Trustee an Opinion of
Counsel that the foregoing have been duly authorized, executed and delivered by
such Subsidiary Guarantor and that such Guarantee is a valid and legally binding
obligation of such Subsidiary Guarantor, enforceable against such Subsidiary
Guarantor in accordance with its terms.


                                       73
<PAGE>
      Each Subsidiary Guarantor hereby agrees that its Guarantee set forth in
Section 11.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Guarantee.

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

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

      Section 11.03.  Subsidiary Guarantors May Consolidate, etc., on
Certain Terms.

      No Subsidiary Guarantor may consolidate with or merge with or into
(whether or not such Subsidiary Guarantor is the Surviving Person) another
Person, whether or not affiliated with such Subsidiary Guarantor, unless:

        (a) subject to the provisions of Section 11.04 hereof, the Person formed
by or surviving any such consolidation or merger (if other than such Subsidiary
Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to
a supplemental indenture in form reasonably satisfactory to the Trustee in
respect of the Notes, this Indenture and such Subsidiary Guarantor's Guarantee;

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

        (c) such transaction does not violate any of Sections 4.03, 4.07, 4.08,
4.09, 4.11, 4.12, 4.13, 4.14, 4.16 and 4.17.

Notwithstanding the foregoing, none of the Subsidiary Guarantors shall be
permitted to consolidate with or merge with or into (whether or not such
Subsidiary Guarantor is the surviving Person), another corporation, Person or
entity pursuant to the preceding sentence if such consolidation or merger would
not be permitted by Section 5.01 hereof.

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


                                       74
<PAGE>
      Except as set forth in Articles 4 and 5 hereof, nothing contained in this
Indenture or in any of the Notes shall prevent any consolidation or merger of
any Subsidiary Guarantor with or into the Company or another Subsidiary
Guarantor, or shall prevent any sale or conveyance of the property of any
Subsidiary Guarantor as an entirety or substantially as an entirety to the
Company or any Subsidiary Guarantor.

      Section 11.04.  Releases of Guarantees.

      In the event of a sale or other disposition of all or substantially all of
the assets of any Subsidiary Guarantor or a sale or other disposition of all of
the capital stock of any Subsidiary Guarantor, to any corporation or other
Person (including an Unrestricted Subsidiary) by way of merger, consolidation,
or otherwise, in a transaction that does not violate any of the covenants of
this Indenture, then such Subsidiary Guarantor (in the event of a sale or other
disposition, by way of such merger, consolidation or otherwise, of all the
capital stock of such Subsidiary Guarantor) shall be released and relieved of
any obligations under its Guarantee and such acquiring corporation or other
Person (in the event of a sale or other disposition of all or substantially all
of the assets of such Subsidiary Guarantor), if other than a Subsidiary
Guarantor, shall have no obligation to assume or otherwise become liable under
such Guarantee; provided, that the Net Proceeds of such sale or other
disposition are applied in accordance with 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, such Subsidiary Guarantor shall ipso facto be released from its
obligations under its Guarantee and the Trustee shall execute any documents
reasonably required in order to evidence the release of any Subsidiary Guarantor
from its obligations under its Guarantee.

      Any Subsidiary Guarantor not released from its obligations under its
Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other obligations of such Subsidiary Guarantor under
this Indenture as provided in this Article 11.

      Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in
accordance with the terms of this Indenture shall be released from and relieved
of its obligations under its Guarantee and any Unrestricted Subsidiary that
becomes a Restricted Subsidiary and any newly created or newly acquired
Subsidiary that is or becomes a Subsidiary shall be required to execute a
Guarantee in accordance with the terms of this Indenture.

      Section 11.05.  Limitation on Subsidiary Guarantor Liability.

      For purposes hereof, each Subsidiary Guarantor's liability shall be that
amount from time to time equal to the aggregate liability of such Subsidiary
Guarantor thereunder, but shall be limited to the lesser of (i) the aggregate
amount of the Obligations of the Company under the Notes and this Indenture and
(ii) the amount, if any, which would not have (A) rendered such Subsidiary
Guarantor "insolvent" (as such term is defined in the Bankruptcy Code and in the
Debtor and Creditor Law of the State of New York) or (B) left it with
unreasonably small capital at the time its Guarantee of the Notes was entered
into, after giving effect to the incurrence of existing Indebtedness immediately
prior to such time; provided that, it shall be a presumption in any lawsuit or
other proceeding in which such Subsidiary Guarantor is a party that the amount


                                       75
<PAGE>
guaranteed pursuant to its Guarantee is the amount set forth in clause (i) above
unless any creditor, or representative of creditors of such Subsidiary
Guarantor, or debtor in possession or trustee in bankruptcy of such Subsidiary
Guarantor, otherwise proves in such a lawsuit that the aggregate liability of
such Subsidiary Guarantor is limited to the amount set forth in clause (ii). In
making any determination as to the solvency or sufficiency of capital of a
Subsidiary Guarantor in accordance with the previous sentence, the right of such
Subsidiary Guarantor to contribution from other Subsidiary Guarantors and any
other rights such Subsidiary Guarantor may have, contractual or otherwise, shall
be taken into account.

      Section 11.06.  "Trustee" to Include Paying Agent.

      In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in Article 10 and this Article 11 shall in such case (unless the context
shall otherwise require) be construed as extending to and including such Paying
Agent within its meaning as fully and for all intents and purposes as if such
Paying Agent were named in Article 10 and this Article 11 in place of the
Trustee.

      Section 11.07.  Subordination of Guarantees.

      The obligations of each of the Subsidiary Guarantors under its Guarantee
pursuant to this Article 11 shall be junior and subordinated to the Senior Debt
of the Subsidiary Guarantor pursuant to Article 10 hereof. For the purposes of
the foregoing sentence, the Trustee and the Holders shall have the right to
receive and/or retain payments or distributions by or on behalf of any of the
Subsidiary Guarantors only at such times as they may receive and/or retain
payments in respect of the Notes pursuant to this Indenture, including Article
10 hereof.



                                   Article 12
                                  MISCELLANEOUS

      Section 12.01.  Trust Indenture Act Controls.

      If any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by TIA Section 318(c), the imposed duties shall control. If any
provisions of this Indenture modifies or excludes any provision of the TIA that
may be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or excluded, as the case may be.

      Section 12.02.  Notices.

      Any notice or communication by the Company or the Subsidiary Guarantors or
the Trustee to the others is duly given if in writing and delivered, in Person

      Section 12.03.  Communication by Holders of Notes with Other Holders
of Notes.

      Holders may communicate pursuant to TIA Section 312(b) with other Holders

      Upon any request or application by the Company or any Subsidiary Guarantor
to the Trustee to take any action under this Indenture, the Company or such

              (a) an Officers' Certificate in form and substance reasonably
      satisfactory to the Trustee (which shall include the statements set forth
      in Section 12.05 hereof) stating that, in the opinion of the signers, all
      conditions precedent and covenants, if any, provided for in this Indenture
      relating to the proposed action have been complied with; and

      satisfactory to the Trustee (which shall include the statements set forth
      in Section 12.05 hereof) stating that, in the opinion of such counsel, all
      such conditions precedent and covenants have been complied with.

      Section 12.05.  Statements Required in Certificate or Opinion.

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

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

              (b) a brief statement as to the nature and scope of the
      examination or investigation upon which the statements or opinions

Company, as such, shall have any liability for any obligations of the Company
under the Notes or this Indenture or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each Holder of Notes, by
accepting a Note, waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.

Indenture, the Notes and the Guarantees shall bind its respective successors.

      In case any provision in this Indenture or in the Notes shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

      Section 12.12.  Counterpart Originals.

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

      Section 12.13.  Table of Contents, Headings, etc.

      The Company promises to pay the principal of this Note on March 15, 2015.

      The Company promises to pay interest on the principal amount of this Note
on each interest payment date, as set forth on the face of this Note, at the
rate of 6 3/8% per annum [(subject to adjustment as provided below)].(1)

      Interest will be payable semiannually (to the holders of record of the
Notes at the close of business on the March 1 or September 1 immediately
preceding the interest payment date) on each interest payment date, commencing
September 15, 2005.(2)

      [The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated March 9, 2005, between the Company and the Initial
Purchasers named therein (the "REGISTRATION RIGHTS AGREEMENT"). In the event
that (i) the Exchange Offer Registration Statement (as defined in the
Registration Rights Agreement) is not declared effective on or prior to the
180th day following the Closing Date (the "EFFECTIVENESS DEADLINE") or, if that
day is not a Business Day, the next day that is a Business Day, (ii) the
Exchange Offer is not consummated on or prior to the earlier of the 30th
Business Day following the date the Exchange Offer Registration Statement was
declared effective or the 210th day following the Closing Date, or, if that day
is not a Business Day, the next day that is a Business Day, or (iii) the Shelf
Registration Statement (as defined in the Registration Rights Agreement) is
required to be filed but is not declared effective by the later of 180 calendar
days after the Closing Date or 90 days after the Shelf Registration Statement is
required to be filed with the Commission, or, if either such day is not a
Business Day, the next day that is a Business Day, or is declared effective by
such date but thereafter ceases to be effective or usable, except if the Shelf
Registration Statement or the Exchange Offer Registration Statement ceases to be
effective or usable as specifically permitted by the penultimate paragraph of
Section 5 of the Registration Rights Agreement (each such event referred to in
clauses (i) through (iii) a "REGISTRATION DEFAULT"), liquidated damages in the
form of additional cash interest ("LIQUIDATED DAMAGES") will accrue on the
affected Notes and the affected Exchange Notes, as applicable, as provided in
the Registration Rights Agreement. The rate of Liquidated Damages will be 0.25%
per annum for the first 90-day period immediately following the occurrence of a
Registration Default, increasing by an additional 0.25% per annum with respect
to each subsequent 90-day period up to a maximum amount of additional interest
of 0.50% per annum, from and including the date on which any such Registration
Default shall occur to, but excluding, the earlier of (1) the date on which all
Registration Defaults have been

cured or (2) the date on which all the Notes and Exchange Notes otherwise become
freely transferable by Holders other than affiliates of the Issuer without
further registration under the Securities Act.](2)

      Interest on this Note will accrue from the most recent date to which
interest has been paid on this Note [or the Note surrendered in exchange for
this Note](3) (or, if there is no existing default in the payment of interest
and if this Note is authenticated between a regular record date and the next
interest payment date, from such interest payment date) or, if no interest has
been paid, from [the Closing Date].(4) Interest will be computed in the basis of
a 360-day year of twelve 30-day months.

      The Company will pay interest on overdue principal, premium, if any, and,
to the extent lawful, interest at a rate per annum that is 1% in excess of
6 3/8%. Interest not paid when due and any interest on principal, premium or
interest not paid when due will be paid to the Persons that are Holders on a
special record date, which will be the 15th day preceding the date fixed by the
Company for the payment of such interest, whether or not such day is a Business
Day. At least 15 days before a special record date, the Company will send to
each Holder and to the Trustee a notice that sets forth the special record date,
the payment date and the amount of interest to be paid.

      2. Indenture.

      This is one of the Notes issued under an Indenture dated as of March 9,
2005 (as amended from time to time, the "Indenture"), among the Company, the
Subsidiary Guarantors party thereto and J.P. Morgan Trust Company, National
Association, as Trustee. Capitalized terms used herein are used as defined in
the Indenture unless otherwise indicated. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of all
such terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Note and the terms of the Indenture, the
terms of the Indenture will control.

      The Notes are general unsecured obligations of the Company. The Indenture
limits the original aggregate principal amount of the Notes to $150,000,000, but
Additional Notes may be issued pursuant to the Indenture, and the originally
issued Notes and all such Additional Notes vote together for all purposes as a
single class.

      3. Optional Redemption.

      (a) The Notes are not redeemable at the Company's option prior to March
15, 2010. From and after March 15, 2010, the Notes will be subject to redemption
at the option of the

                2013 and thereafter.    100.000%
</TABLE>

      (b) Notwithstanding the provisions of clause (a) of this paragraph 3,
prior to March 15, 2008 the Company may, at its option, on any one or more
occasions, redeem up to 35% of the original aggregate principal amount of Notes
at a redemption price equal to 106.375% of the principal amount thereof, plus
accrued and unpaid interest, if any, thereon to the redemption date, with the
net proceeds of sales of public Equity Interests of the Company; provided that
at least 65% of the original aggregate principal amount of Notes remain
outstanding immediately after the occurrence of such redemption; and provided,
further, that any such redemption shall occur within 60 days after the date of
the closing of the related sale of such Equity Interests.

      4. Mandatory Redemption.

      Except as set forth in paragraph 5 below, the Company shall not be
required to make mandatory redemption or sinking fund payments with respect to
the Notes.

      5. Repurchase at Option of Holder.

      (a) Upon the occurrence of a Change of Control, each Holder of Notes shall
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of such Holder's Notes pursuant to the
offer described below (the "Change of Control Offer") at an offer price in cash
equal to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest, if any, thereon to the date of purchase (the "Change of Control
Payment"). The right of the Holders of the Notes to require the Company to
repurchase such Notes upon a Change of Control may not be waived by the Trustee
without the approval of the Holders of the Notes required by Section 9.02 of the
Indenture. 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 offering to repurchase Notes pursuant to
the procedures required by the Indenture and described in such notice. The
Change of Control Payment shall be made on a Business Day not less than 30 days
nor more than 60 days after such notice is mailed. The Company and each
Subsidiary Guarantor will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

      (b) If the Company or a Restricted Subsidiary consummates any Asset Sales
permitted by the Indenture, when the aggregate amount of Excess Proceeds exceeds
$10.0


                                      A-6
<PAGE>
million, the Company shall make an Asset Sale Offer to purchase the
maximum principal amount of Notes and any other pari passu Indebtedness to which
the Asset Sale Offer applies that may be purchased out of the Excess Proceeds,
at an offer price in cash in an amount equal to, in the case of the Notes, 100%
of the principal amount thereof, plus accrued and unpaid interest thereon to the
date of purchase or, in the case of any pari passu Indebtedness, 100% of the
principal amount thereof (or with respect to discount pari passu Indebtedness,
the accreted value thereof) on the date of purchase, in each case, in accordance
with the procedures set forth in Section 3.09 of the Indenture or the agreements
governing the pari passu Indebtedness, as applicable. To the extent that the
aggregate principal amount (or accreted value, as the case may be) of Notes and
pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than
the Excess Proceeds, the Company may use any remaining Excess Proceeds for
general corporate purposes. If the sum of (i) the aggregate principal amount of
Notes surrendered by Holders thereof and (ii) the aggregate principal amount or
accreted value, as the case may be, of pari passu Indebtedness surrendered by
holders or lenders thereof exceeds the amount of Excess Proceeds, the Trustee
and the trustee or other lender representative for the pari passu Indebtedness
shall select the Notes and the other pari passu Indebtedness to be purchased on
a pro rata basis, based on the aggregate principal amount (or accreted value, as
applicable) thereof surrendered in such Asset Sale Offer. Upon completion of
such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

      6. Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in integral multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest will cease to accrue on the aggregate
principal amount of the Notes called for redemption.

      7. Registered Form; Denominations; Transfer; Exchange.

      The Notes are in registered form without coupons in denominations of
$1,000 principal amount and any multiple of $1,000 in excess thereof. A Holder
may register the transfer or exchange of Notes in accordance with the Indenture.
The Trustee may require a Holder to furnish appropriate endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. Pursuant to the Indenture, there are certain periods during which
the Trustee will not be required to issue, register the transfer of or exchange
any Note or certain portions of a Note.

      8. Persons Deemed Owners. The registered Holder of a Note shall be treated
as its owner for all purposes.

      9. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or the tender offer or exchange offer for, such Notes), and any
existing Default or Event of Default under, 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. Without the consent
of any Holder of


                                      A-7
<PAGE>
a Note, the Indenture or the Notes may be amended on supplemented to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to provide for the assumption of
the Company's obligations to Holders of the Notes in case of a merger or
consolidation, to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights under the Indenture of any such Holder, or to comply with the
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the Trust Indenture Act.

      10. Defaults and Remedies. Events of Default include: (i) default for 30
consecutive days in the payment when due of interest on the Notes (whether or
not prohibited by the provisions of Article 10 of the Indenture); (ii) default
in payment when due of the principal of or premium, if any, on the Notes
(whether or not prohibited by the provisions of Article 10 of the Indenture);
(iii) failure by the Company to comply with the provisions of Article 5 of the
Indenture; (iv) failure by the Company for 30 consecutive days after notice from
the Trustee or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding to comply with the provisions of Sections 4.03, 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16 and 4.17 of the Indenture; (v)
failure by the Company for 60 consecutive days after notice from the Trustee or
the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding to comply with any of its other agreements or covenants in, or
provisions of, this Note or in the Indenture; (vi) except as permitted by the
Indenture, any Guarantee shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect or a Subsidiary Guarantor, or any Person acting on behalf of a Subsidiary
Guarantor, shall deny or disaffirm such Subsidiary Guarantor's obligations under
its Guarantee; (vii) default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any Restricted Subsidiary,
whether such Indebtedness or guarantee now exists, or is created after the date
of the Indenture, which default (a) is caused by a failure to pay principal of
or premium, if any, or interest, if any, on such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such
default (a "Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there is then existing a Payment Default or the
maturity of which has been so accelerated, aggregates $10.0 million or more;
provided, that if any such default is cured or waived or any such acceleration
rescinded, or such Indebtedness is repaid, within a period of 10 days from the
continuation of such default beyond the applicable grace period or the
occurrence of such acceleration, as the case may be, such Event of Default under
the Indenture and any consequential acceleration of the Notes shall be
automatically rescinded; (viii) a final non-appealable judgment or order or
final non-appealable judgments or orders are rendered against the Company or any
Restricted Subsidiary that remain unpaid or discharged for a period of 60 days
and that require the payment in money, either individually or in an aggregate
amount, that is more than $10.0 million; and (ix) certain events of bankruptcy
or insolvency with respect to the Company or any Significant Subsidiary or any
group of Subsidiaries that, taken together, would constitute a Significant
Subsidiary. If any Event of Default (other than an Event of Default described in
clause (ix) above) 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. Notwithstanding. the foregoing, in the
case of an Event of Default arising


                                      A-8
<PAGE>
from certain events of bankruptcy or insolvency with respect to the Company, any
Significant Subsidiary or any group of Subsidiaries that, taken together, would
constitute a Significant Subsidiary, all outstanding Notes will become due and
payable without further action or notice. Holders of the Notes 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 or premium 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, within 5 Business
days after becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

      11. Subordination. The Notes are subordinated to Senior Debt of the
Company. To the extent provided in the Indenture, Senior Debt must be paid
before the Notes may be paid. The Company agrees, and each Holder by accepting a
Note agrees, that the Indebtedness evidenced by the Notes, including, but not
limited to, the payment of principal of, premium, if any, and interest on the
Notes, and any other payment Obligation of the Company in respect of the Notes
is subordinated in right of payment, to the extent and in the manner provided in
the Indenture, to the prior payment in full in cash of all Senior Debt of the
Company (whether outstanding on the date hereof or hereafter created, incurred,
assumed or guaranteed) and authorizes the Trustee to give effect and appoints
the Trustee as attorney-in-fact for such purpose.

      12. Trustee Dealings with Company. The Indenture contains certain
limitations on the rights of the Trustee, should it become a creditor of the
Company, to obtain payment of claims in certain cases, or to realize on certain
property received in respect of any such claim as security or otherwise. The
Trustee will be permitted to engage in other transactions; however, if it
acquires any conflicting interest it must eliminate such conflict within 90
days, apply to the Commission for permission to continue or resign.

      13. No Recourse Against Others. No director, officer, employee,
incorporator or stockholder of the Company, as such, shall have any liability
for any obligations of the Company under the Notes or the Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Notes, by accepting a Note, waives and releases all
such liability. The waiver and release are part of the consideration for
issuance of the Notes. Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the Commission that such
a waiver is against public policy.

14. Authentication.

      This Note is not valid until the Trustee (or Authenticating Agent) signs
the certificate of authentication on the other side of this Note.

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

            Notes due 2015 (the "NOTES")
            Issued under the Indenture (the "INDENTURE") dated as
            as of March 9, 2005 relating to the Notes

Ladies and Gentlemen:

      Terms are used in this Certificate as used in Regulation S ("Regulation
S") under the Securities Act of 1933, as amended (the "Securities Act"), except
as otherwise stated herein.

      [CHECK A OR B AS APPLICABLE.]

   [ ]A.    This Certificate relates to our proposed transfer of $____ principal
            amount of Notes issued under the Indenture. We hereby certify as
            follows:

            1.    The offer and sale of the Notes was not and will not be made
                  to a person in the United States (unless such person is
                  excluded from the definition of "U.S. person" pursuant to Rule
                  902(k)(2)(vi) or the account held by it for which it is acting
                  is excluded from the definition of "U.S. person" pursuant to
                  Rule 902(k)(2)(i) under the circumstances described in Rule
                  902(h)(3)) and such offer and sale was not and will not be
                  specifically targeted at an identifiable group of U.S.
                  citizens abroad.

            2.    Unless the circumstances described in the parenthetical in
                  paragraph 1 above are applicable, either (a) at the time the
                  buy order was originated, the buyer was outside the United
                  States or we and any person acting on our behalf reasonably
                  believed that the buyer was outside the United States or (b)
                  the transaction was executed in, on or through the facilities
                  of a designated offshore securities market, and neither we nor
                  any person acting on our behalf knows that the transaction was
                  pre-arranged with a buyer in the United States.


                                      E-1
<PAGE>
            3.    Neither we, any of our affiliates, nor any person acting on
                  our or their behalf has made any directed selling efforts in
                  the United States with respect to the Notes.

            4.    The proposed transfer of Notes is not part of a plan or scheme
                  to evade the registration requirements of the Securities Act.

            5.    If we are a dealer or a person receiving a selling concession,
                  fee or other remuneration in respect of the Notes, and the
                  proposed transfer takes place during the Restricted Period (as
                  defined in the Indenture), or we are an officer or director of
                  the Company or an Initial Purchaser (as defined in the
                  Indenture), we certify that the proposed transfer is being
                  made in accordance with the provisions of Rule 904(b) of
                  Regulation S.

   [ ]B.    This Certificate relates to our proposed exchange of $____ principal
            amount of Notes issued under the Indenture for an equal principal
            amount of Notes to be held by us. We hereby certify as follows:

            1.    At the time the offer and sale of the Notes was made to us,
                  either (i) we were not in the United States or (ii) we were
                  excluded from the definition of "U.S. person" pursuant to Rule
                  902(k)(2)(vi) or the account held by us for which we were
                  acting was excluded from the definition of "U.S. person"
                  pursuant to Rule 902(k)(2)(i) under the circumstances
                  described in Rule 902(h)(3); and we were not a member of an
                  identifiable group of U.S. citizens abroad.

            2.    Unless the circumstances described in paragraph 1(ii) above
                  are applicable, either (a) at the time our buy order was
                  originated, we were outside the United States or (b) the
                  transaction was executed in, on or through the facilities of a
                  designated offshore securities market and we did not
                  pre-arrange the transaction in the United States.

            3.    The proposed exchange of Notes is not part of a plan or scheme
                  to evade the registration requirements of the Securities Act.

                                    Guarantee


      Each of the Subsidiary Guarantors hereby, jointly and severally and
unconditionally guarantees to each Holder of a Note authenticated and delivered
by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of this Indenture, the Notes or the
obligations of the Company hereunder or thereunder, that: (a) the principal of,
and premium and interest on, the Notes shall be promptly paid in full when due,
whether at maturity, by acceleration, redemption or otherwise, and interest on
the overdue principal of, and interest on premium and interest on, the Notes, if
any, if lawful, and all other obligations of the Company to the Holders or the
Trustee hereunder or thereunder shall be promptly paid in full or performed, all
in accordance with the terms hereof and thereof; and (b) in case of any
extension of time of payment or renewal of any Notes or any of such other
obligations, that same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed or any performance so guaranteed for whatever reason, the
Subsidiary Guarantors shall be jointly and severally obligated to pay the same
immediately.

      The obligations of the Subsidiary Guarantors to the Holders of Notes and
to the Trustee pursuant to this Guarantee and the Indenture (including the
subordination provisions thereof) are expressly set forth in Article 11 of the
Indenture, and reference is hereby made to such Indenture for the precise terms
of this Guarantee. The terms of Article 11 of the Indenture are incorporated
herein by reference.

      This is a continuing Guarantee and shall remain in full force and effect
and shall be binding upon each of the Subsidiary Guarantors and its respective
successors and assigns to the extent set forth in the Indenture until full and
final payment of all of the Company's Obligations under the Notes and the
Indenture and shall inure to the benefit of the Trustee and the Holders of Notes
and their successors and assigns and, in the event of any transfer or assignment
of rights by any Holder of Notes or the Trustee, the rights and privileges
herein conferred upon that party shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions hereof.
Notwithstanding the foregoing, any Subsidiary Guarantor that satisfies the
provisions of Section 11.04 of the Indenture shall be released of its
obligations hereunder. This is a Guarantee of payment and not a, guarantee of
collection.

      This Guarantee shall not be valid or obligatory for any purpose until the
certificate of authentication on the Note upon which this Guarantee is noted
shall have been executed by the Trustee under the Indenture by the manual
signature of one of its authorized officers.

      For purposes hereof, each Subsidiary Guarantor's liability will be that
amount from time to time equal to the aggregate liability of such Subsidiary
Guarantor hereunder but shall be limited to the lesser of (i) the aggregate
amount of the obligations of the Company under the Notes and the Indenture and
(ii) the amount, if any, which would not have (A) rendered such
<PAGE>
Subsidiary Guarantor "insolvent" (as such term is defined in the federal
Bankruptcy Code and in the Debtor and Creditor law of the State of New York) or
(B) left it with unreasonably small capital at the time its Guarantee was
entered into, after giving effect to the incurrence of existing Indebtedness
immediately prior to such time; provided that, it shall be a presumption in any
lawsuit or other proceeding in which such Subsidiary Guarantor is a party that
the amount guaranteed pursuant to its Guarantee is the amount set forth in
clause (i) above unless any creditor, or representative of creditors of such
Subsidiary Guarantor, or debtor in possession or trustee in bankruptcy of such
Subsidiary Guarantor, otherwise proves in such a lawsuit that the aggregate
liability of such Subsidiary Guarantor is limited to the amount set forth in
clause (ii). The Indenture provides that, in making any determination as to the
solvency or sufficiency of capital of a Subsidiary Guarantor in accordance with
the previous sentence, the right of such Subsidiary Guarantor to contribution
from other Subsidiary Guarantors and any other rights such Subsidiary Guarantor
may have, contractual or otherwise, shall be taken into account.

      Capitalized terms used herein have the same meanings given in the
Indenture unless otherwise indicated.
