contemplation of, such other Person merging with or into or becoming a
Subsidiary of such specified Person, and (ii) Indebtedness secured by a Lien

Notes except that the date from which interest on the Additional Notes will
accrue may be different.

         "Adjusted Consolidated Net Tangible Assets" means (without
duplication), as of the date of determination, (i) the sum of (a) discounted
future net revenues from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with the Commission's
guidelines before any state or federal income taxes, with no less than 80% of
the discounted future net revenues estimated by one or more nationally
recognized firms of independent petroleum engineers in a reserve report prepared
as of the end of the Company's most recently completed fiscal year, as increased
by, as of the date of determination, the estimated discounted future net
revenues from (1) estimated proved oil and gas reserves acquired since the date
of such year-end reserve report, and (2) estimated oil and gas reserves
attributable to upward revisions of estimates of proved oil and gas reserves
since the date of such year-end reserve report due to exploration, development
or exploitation activities, in each case calculated in accordance with the
Commission's guidelines (utilizing the prices utilized in such year-end reserve
report) increased by the accretion of the discount from the date of the reserve
report to the date of determination, and decreased by, as of the date of
determination, the estimated discounted future net revenues from (3) estimated
proved oil and gas reserves produced or disposed of since the date of such
year-

                                        1

end reserve report and (4) estimated oil and gas reserves attributable to
downward revisions of estimates of proved oil and gas reserves since the date of
such year-end reserve report due to changes in geological conditions or other
factors which would, in accordance with standard industry practice, cause such
revisions, in each case calculated in accordance with the Commission's
guidelines (utilizing the prices utilized in such year-end reserve report);
provided that, in the case of each of the determinations made pursuant to clause
(1) through (4), such increases and decreases shall be as estimated by the
Company's petroleum engineers, unless in the event that there is a Material
Change as a result of such acquisitions, dispositions or revisions, then the
discounted future net revenues utilized for purposes of this clause (i) (a)
shall be confirmed in writing by one or more nationally recognized firms of
independent petroleum engineers, (b) the capitalized costs that are attributable
to oil and gas properties of the Company and its Restricted Subsidiaries to
which no proved oil and gas reserves are attributable, based on the Company's
books and records as of a date no earlier than the date of the Company's latest
annual or quarterly financial statements, (c) the Net Working Capital on a date
no earlier than the date of the Company's latest annual or quarterly financial
statements and (d) the greater of (1) the net book value on a date no earlier

annual or quarterly financial statements, minus (ii) the sum of (a) minority

Subsidiaries reflected in the Company's latest audited financial statements, and

Commission's guidelines, attributable to reserves subject to Dollar-Denominated
Production Payments which, based on the estimates of production and price
assumptions included in determining the discounted future net revenues specified
in (i) (a) above, would be necessary to fully satisfy the payment obligations of
the Company and its Restricted Subsidiaries with respect to Dollar-Denominated
Production Payments on the schedules specified with respect thereto. If the
Company changes its method of accounting from the successful efforts method to
the full cost method or a similar method of accounting, "Adjusted Consolidated

using the successful efforts method of accounting.

                           (A)      the amount of Notes to be authenticated and

                           (B)      whether the Notes are to be Initial Notes or

                  provision of Article 4,

                           (D)      whether the Notes are to be issued as one or

         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

         Exchange Offer Registration Statement and consummation of the exchange
         offer thereunder (and receipt by the Trustee of an Officers'

         Section 2.03. Registrar, Paying Agent and Authenticating Agent; Paying
Agent to Hold Money in Trust. Error! Bookmark not defined. 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 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

                                       25

<PAGE>

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, 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

                                       26

<PAGE>

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
normal 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.

         Section 2.09. Registration, Transfer and Exchange. Error! Bookmark not
defined. 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.

                                       27

<PAGE>

         (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 may 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

                                       28

<PAGE>

         Note of like tenor and amount that does not bear the Restricted Legend,
         registered in the name of such Holder.

         (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

                                       29

<PAGE>

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.

                  (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 canceled Certificated Note, registered in the name of
         the Holder thereof.

                  (4)      Certificated Note to Certificated Note. If a
         Certificated Note is transferred or exchanged for another Certificated
         Note, the Trustee will (x) cancel the Certificated Note being
         transferred or exchanged, (y) deliver one or more new Certificated
         Notes in authorized denominations having an aggregate principal amount
         equal to the principal amount of such transfer or exchange to the
         transferee (in the case of a transfer) or the Holder of the canceled
         Certificated Note (in the case of an exchange), registered in the name
         of such transferee or Holder, as applicable, and (z) if such transfer
         or exchange involves less than the entire principal amount of the
         canceled Certificated Note, deliver to the Holder thereof one or more
         Certificated Notes in authorized denominations having an aggregate
         principal amount equal to the untransferred or unexchanged portion of
         the canceled Certificated Note, registered in the name of the Holder
         thereof.

         Section 2.10. Restrictions on Transfer and Exchange. (a) The transfer
or exchange of any Note (or a beneficial interest therein) may only be made in
accordance with this Section and Section 2.09 and, in the case of a Global Note

                                       30

(or a beneficial interest therein), the applicable rules and procedures of the
Depositary. The Trustee shall refuse to register any requested transfer or
exchange that does not comply with the preceding sentence.

         (b)      Subject to paragraph (c), the transfer or exchange of any Note
(or a beneficial interest therein) of the type set forth in column A below for a
Note (or a beneficial interest therein) of the type set forth opposite in column
B below may only be made in compliance with the certification requirements (if
any) described in the clause of this paragraph set forth opposite in column C
below.

                  (1)      No certification is required.

                  (2)      The Person requesting the transfer or exchange must
         deliver or cause to be delivered to the Trustee a duly completed
         Regulation S Certificate; provided that if the requested transfer or
         exchange is made by the Holder of a Certificated Note that does not
         bear the Restricted Legend, then no certification is required.

                  (3)      The Person requesting the transfer or exchange must
         deliver or cause to be delivered to the Trustee (x) a duly completed
         Rule 144A Certificate or (y) a duly completed Regulation S Certificate,
         and/or an Opinion of Counsel and such other certifications and evidence
         as the Company may reasonably require in order to determine that the
         proposed transfer or exchange is being made in compliance with the
         Securities Act and any applicable securities laws of any state of the
         United States; provided that if the requested transfer or exchange is
         made by the Holder of a Certificated Note that does not bear the
         Restricted Legend, then no certification is required. In the event that
         (i) the requested transfer or exchange takes place after the Restricted
         Period and a duly completed Regulation S Certificate is delivered to
         the Trustee or (ii) a Certificated Note that does not bear the
         Restricted Legend is surrendered for transfer or exchange, upon
         transfer or exchange the Trustee will deliver a Certificated Note that
         does not bear the Restricted Legend.

                  (4)      The Person requesting the transfer or exchange must
         deliver or cause to be delivered to the Trustee a duly completed Rule
         144A Certificate.

                  (5)      Notwithstanding anything to the contrary contained
         herein, no such exchange is permitted if the requested exchange
         involves a beneficial interest in a Temporary Offshore Global Note. If
         the requested transfer 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 Counsel and such other certifications
         and evidence as the Company may reasonably require in order to
         determine that the proposed transfer is being made in compliance with
         the Securities Act and any applicable securities laws of any state of
         the United States. If the requested transfer or exchange involves a
         beneficial interest in a Permanent Offshore Global Note, no
         certification is required and the Trustee will deliver a Certificated
         Note that does not bear the Restricted Legend.

         (c)      No certification is required in connection with any transfer
or exchange of any Note (or a beneficial interest therein)

                  (1)      after such Note is eligible for resale pursuant to
         Rule 144(k) under the Securities Act (or a successor provision);
         provided that the Company has provided the Trustee with an Officer's
         Certificate to that effect, and the Company may require from any Person
         requesting a transfer or exchange in reliance upon this clause (1) an
         opinion of counsel and any other reasonable certifications and evidence
         in order to support such certificate; or

                  (2)(x)   sold pursuant to an effective registration statement
         or (y) which is validly tendered for exchange into an Exchange Note
         pursuant to an Exchange Offer.

         Any Certificated Note delivered in reliance upon this paragraph will
not bear the Restricted Legend.

         (d)      The Trustee will retain copies of all certificates, opinions
and other documents received in connection with the transfer or exchange of a
Note (or a beneficial interest therein), and the Company will have the right to
inspect and make copies thereof at any reasonable time upon written notice to
the Trustee.

         Section 2.11. Regulation S Temporary Offshore Global Notes. (a) Each
Note originally sold by the Initial Purchasers in reliance upon Regulation S
will be evidenced by one or more Offshore Global Notes that bear 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
principal amount of such Permanent Offshore Global Note by the amount of such
beneficial interest.

         (d)      Notwithstanding anything to the contrary contained herein, no
owner of a beneficial interest in a Temporary Offshore Global Note shall be
entitled to receive payment of principal or interest on such beneficial interest
or other amounts in respect of such beneficial 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 interest to be paid.

                            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 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.

                                       34

         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 threedays (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.

         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 35 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.

         Section 3.07. Optional Redemption.

         (a)      Except as set forth in clause (b) of this Section 3.07, the
Company shall not have the option to redeem the Notes pursuant to this Section
3.07 prior to July 15, 2008. From and after July 15, 2008, the Company shall
have the option to redeem the Notes, in whole or in part, at the redemption

accrued and unpaid interest thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on July 15 of each of the

         (b)      Notwithstanding the provisions of clause (a) of this Section
3.07, at any time prior to July 15, 2006, 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 107.375% of the principal amount
thereof, plus accrued and unpaid interest, if any, thereon to the redemption
date with all or a portion of 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 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
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Company shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof, giving effect to any related offer
for pari passu Indebtedness pursuant to Section 4.10, (the "Offer Amount") or,
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.

                                       37

<PAGE>

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest 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.

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

Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer
shall remain open;

Asset Sale Offer may only elect to have all of such Note purchased and may not
elect to have only a portion of such Note purchased;

Asset Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Company, the Depositary, if appointed by
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

                                       38

<PAGE>

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 new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered (or transferred by book-entry transfer).

         If any of the Notes subject to an Asset Sale Offer is in the form of a
Global Note, then such notice may be modified in form but not substance to the
extent appropriate to accord with the procedures of the Depositary applicable to
repurchases.

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

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

                                    COVENANTS

         Section 4.01. Payment of Notes.

         The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Company or a Subsidiary thereof,
holds as of 10:00 a.m. Eastern Time on the due date money deposited by the

                                       39

<PAGE>

Company in immediately available funds and designated for and sufficient to pay
all such amounts then due.

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

         Section 4.02. Maintenance of Office or Agency.

         The Company shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where principal, premium, if any, and
interest on the Notes will be paid and where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

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

         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 Trustees, the Holders and prospective
Holders (upon request) as if the Company were subject to the

                                       40

<PAGE>

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 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 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

                                       42

<PAGE>

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), (6) and (7) of the next succeeding paragraph), is less
than the sum of (i) 50% of the Consolidated Net Income of the Company for the
period (taken as one accounting period) from the beginning of the first fiscal
quarter commencing after the date of this Indenture to the end of the Company's
most recently ended fiscal quarter for which 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 (ii) 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
(iii) 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; provided, however, that
the foregoing provisions of this paragraph (c) will not prohibit Restricted
Payments in an aggregate amount not to exceed $20 million.

         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
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

                                       43
<PAGE>

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; (6) cash
payments made by the Company for the repurchase, redemption or other acquisition
or retirement of the Company's 8 3/4% Senior Subordinated Notes due 2007; (7)
cash payments made by the Company, not to exceed $25 million in the aggregate,
for the repurchase, redemption or other acquisition or retirement of the
Company's 6% Convertible Subordinated Debentures due 2007 and the 5 3/4% Trust
Convertible Preferred Securities.

         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

                                       44

<PAGE>

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
         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 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) $225.0
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), (c) the guarantee by any Subsidiary Guarantor of any
Indebtedness that is permitted by this Indenture to be incurred by the Company;
(d) all Indebtedness of the Company and its Restricted Subsidiaries in existence
as of the date of this Indenture; (e) 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

                                       46

<PAGE>

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; (f) 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;
(g) 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; (h) 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; (i)
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 (j) of this paragraph in respect of Indebtedness previously
incurred pursuant to this clause (i), does not exceed $10.0 million at any one
time outstanding; (j) 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 (j)); (k)
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; (l) Indebtedness consisting of obligations in
respect of purchase price adjustments, guarantees or indemnities in connection
with the acquisition or disposition of assets; and (m) 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

                                       47

<PAGE>

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 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

                                       48

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
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

                                       49

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

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 accepted for payment pursuant to the Change of Control Offer shall cease
to accrue interest, if any, after the Change of Control Payment Date; (6) that
Holders electing to have any Notes purchased pursuant to a Change of Control
Offer shall be required to surrender the Notes, with the form entitled "Option
of Holder to Elect Purchase" on the reverse of the Notes completed, to the
Paying Agent at the address specified in the notice prior to the close of
business on the third Business Day preceding the Change of Control Payment Date;
(7) that Holders shall be entitled to withdraw their election if the Paying
Agent receives, not later than the close of business on the second Business Day
preceding the Change of Control Payment Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of Notes delivered for purchase, and a statement that such Holder is
withdrawing his election to have the Notes purchased; and (8) that

                                       50

<PAGE>

Holders whose Notes are being purchased only in part shall be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered,
which unpurchased portion must be equal to $1,000 in principal amount or an
integral multiple thereof. The Company and each Subsidiary Guarantor shall
comply with the requirements of Rule l4e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable to such party in connection with the repurchase of
the Notes as a result of a Change of Control.

         (b)      On a Business Day that is no earlier than 30 days nor later
than 60 days from the date that the Company mails or causes to be mailed notice
of the Change of Control to the Holders (the "Change of Control Payment Date"),
the Company shall, to the extent lawful, (i) accept for payment all Notes or
portions thereof properly tendered pursuant to the Change of Control Offer, (ii)
deposit with the Paying Agent an amount equal to the Change of Control Payment
in respect of all the Notes or portions thereof so tendered and (iii) deliver or
cause to be delivered to the Trustee the Notes so accepted together with an
Officers' Certificate stating the aggregate principal amount of such Notes or
portions thereof being purchased by the Company. The Paying Agent shall promptly
mail to each Holder of the Notes so tendered the Change of Control Payment for
such Notes, and the Trustee shall promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount
to any unpurchased portion of the Notes surrendered, if any; provided that each
such new Note shall be in a principal amount of $1,000 or an integral multiple
thereof. The Company shall publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

         The Change of Control provisions described above shall be applicable
whether or not any other provisions of this Indenture are applicable.

         The Company shall not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements set
forth in this Section 4.13 and purchases all Notes (or portions thereof) validly
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
guarantee or be required to execute a Guarantee in accordance with Section
11.02.

         Section 4.15. Corporate Existence.

         Subject to Article 5 hereof, the Company and the Subsidiaries shall do
or cause to be done all things necessary to preserve and keep in full force and
effect (i) its corporate existence, and the corporate, partnership or other
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 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
any Indebtedness that is subordinate or junior in right of payment to any Senior
Debt of the Company and senior in any respect in right of payment to the Notes
and (ii) the Subsidiary Guarantors shall not directly or indirectly incur,
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
and senior in any respect in right of payment to the Guarantees; provided,
however, that the foregoing limitations shall not apply to distinctions between
categories of Indebtedness that exist by reason of any Liens arising or created
in respect of some but not all such Indebtedness.

         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
Business.

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

         The Company shall not consolidate or merge with or into (whether or not
the Company is the surviving corporation), or sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of its properties or
assets, in one or more related transactions, to another Person, and the Company
may not permit

<PAGE>

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
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
obligor under this Indenture) will, at the time of such transaction or series of
transactions and after giving pro forma effect thereto as if such transaction or
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
assets to another Wholly Owned Restricted Subsidiary.

         Section 5.02. Successor Corporation Substituted.

         Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company in 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

                                       53

<PAGE>

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;

                  (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

                                       54

<PAGE>

         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,

                           (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

                                       55

<PAGE>

                  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 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

                                       56

<PAGE>

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).

Section 8.03 hereof, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, Sections 6.01(3) (but only with respect to the Company's
failure to observe or perform the covenants, conditions and agreements of the
Company under clause (iv) of Section 5.01, 6.01(4), 6.01(7) and 6.01(8) hereof
shall not constitute Events of Default.

         Section 8.04. Conditions to Legal or Covenant Defeasance.

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

         In order to exercise either Legal Defeasance or Covenant Defeasance:

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

         (b)      in the case of an election under Section 8.02 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

                                       68

<PAGE>

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

         (d)      no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or insofar
as Section 6.01(9) or 6.01(10) hereof is concerned, at any time in the period
ending on the 91st day after the date of deposit;

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

         (f)      the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that after the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally;

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

         (h)      the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

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

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due

                                       69

<PAGE>

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

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

         Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may. be the opinion delivered under Section
8.04(a) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

         Section 8.06. Repayment to Company.

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

         Section 8.07. Reinstatement.

         If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company and the Subsidiary Guarantors
under this Indenture, the Notes and the Guarantees shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
hereof, as the case may be; provided, however, that if the Company or any
Subsidiary Guarantor

                                       70

<PAGE>

makes any payment of principal of, premium, if any, or interest on any Note
following the reinstatement of its obligations, the Company or such Subsidiary
Guarantor shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money held by the Trustee or Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

         Section 9.01. Without Consent of Holders of Notes.

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

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

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

         (c)      to provide for the assumption of the Company's obligations to
the Holders of the Notes in the case of a merger or consolidation pursuant to
Article 5 hereof;

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

         (e)      to secure the Notes; or

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

         Upon the request of the Company accompanied by a resolution of 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 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.

                                       71

         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 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;

                                       72

<PAGE>

         (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

                                       73

<PAGE>

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 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

                                       74

<PAGE>

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.

Debt) with respect to such Designated Senior Debt and all other Obligations with
respect thereto.

         Section 10.03. Liquidation; Dissolution; Bankruptcy.

         (a)      Upon any payment or distribution of property or securities to

relating to the Company or its property, or in an assignment for the benefit of
creditors or any marshalling of the Company's assets and liabilities:

<PAGE>

                  (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 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 hereof
         provided that the applicable deposit does not violate Article 8 or 10
         of this Indenture); and

                  (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 that the applicable
         deposit does not violate Article 8 or 10 of this Indenture); and

                                       76

<PAGE>

                  (2)      until all Obligations with respect to Senior Debt of
         such Subsidiary Guarantor (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 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).

         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), (c)(1), (a)(2), (b)(2) and (c)(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

                                       77

<PAGE>

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 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

                                       78

<PAGE>

         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.

         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

                                       79

<PAGE>

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.

         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

                                       80

<PAGE>

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.

         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

                                       81

<PAGE>

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 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

                                       82

<PAGE>

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

                                       83

<PAGE>

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.

         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

                                       84

<PAGE>

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.

         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, 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

                                       85

<PAGE>

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
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.

         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

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

                  (c)      a statement that, in the opinion of such Person, he

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.

         [The Holder of this Note is entitled to the benefits of the
Registration Rights Agreement, dated July 21, 2003, 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

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
7 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 July 21,
2003 (as amended from time to time, the "Indenture"), among the Company, the
Subsidiary Guarantors party thereto and Bank One, National Association, as

unless otherwise indicated. The terms of the Notes include those stated in the

purposes as a single class.

         (a)      The Notes are not redeemable at the Company's option prior to
July 15, 2008. From and after July 15, 2008, the Notes will be subject to
redemption at the option of the Company, in whole or in part, upon not less than
30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest thereon to the applicable redemption date, if redeemed during the

<TABLE>

Year                               Percentage
<C>                                <C>

2010..........................      101.229%
2011 and thereafter...........      100.000%
</TABLE>

         (b)      Notwithstanding the provisions of clause (a) of this paragraph
3, prior to July 15, 2006 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 107.375% 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

                                      A-6

<PAGE>

$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 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

                                      A-7

<PAGE>

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 may 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 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,

                                      A-8

<PAGE>

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 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

                                      A-9

<PAGE>

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.

15.      Governing Law.

                   Issued under the Indenture (the "INDENTURE") dated as
                   as of July 21, 2003 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)

                                      E-1

<PAGE>

                         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.

                     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

<PAGE>

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 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.
