usage. Each Note shall be dated the date of its authentication. The Notes shall
be in denominations of $2,000 and integral multiples of $1,000.

      The terms and provisions contained in the Notes shall constitute, and are

      One Officer shall sign the Notes for the Company by manual or facsimile
signature.

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

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

      The Trustee shall, upon receipt of a written order of the Company signed
by one Officer (an "Authentication Order"), authenticate Notes for original
issue that may be validly issued under this Indenture, including any Additional
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed the aggregate principal amount of Notes authorized for issuance by the
Company pursuant to one or more Authentication Orders, except as provided in
Section 2.07 hereof.

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

Section 2.03 Registrar and Paying Agent.

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

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

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

                                       35


Section 2.05 Holder Lists.

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

Section 2.06 Transfer and Exchange.

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

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

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

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

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

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

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

                                       36


      Unrestricted Global Note. No written orders or instructions shall be
      required to be delivered to the Registrar to effect the transfers
      described in this Section 2.06(b)(1).

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

                  (A) both:

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

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

                  (B) both:

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

                        (ii)  instructions given by the Depositary to the

                  transfer or exchange referred to in (1) above;

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

      Registrar receives the following:

                  (A) if the transferee will take delivery in the form of a

            must deliver a certificate in the form of Exhibit B hereto,
            including the certifications in item (1) thereof; and

                  (B) if the transferee will take delivery in the form of a

      Global Note for Beneficial Interests in an Unrestricted Global Note. A
      beneficial interest in any Restricted Global Note may be exchanged by any
      holder thereof for a beneficial interest in an Unrestricted Global Note or
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in an Unrestricted Global Note if the exchange or

            in Rule 144) of the Company;

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

                  (C) such transfer is effected by a Broker-Dealer pursuant to

                        (i)   if the holder of such beneficial interest in a
                  Restricted Global Note proposes to exchange such beneficial
                  interest for a beneficial interest in an Unrestricted Global

            Registrar to the effect that such exchange or transfer is in
            compliance with the Securities Act and that the restrictions on
            transfer contained herein and in the Private Placement Legend are no
            longer required in order to maintain compliance with the Securities
            Act.

                  If any such transfer is effected pursuant to subparagraph (B)
            or (D) above at a time when an Unrestricted Global Note has not yet
            been issued, the Company shall issue and, upon receipt of an

            in the form of, a beneficial interest in a Restricted Global Note.

shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

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

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

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

Section 2.09 Treasury Notes.

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

Section 2.10 Temporary Notes.

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

                                       47


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

Section 2.11 Cancellation.

      The Company at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and will dispose of
canceled Notes in accordance with its customary procedure (subject to the record
retention requirement of the Exchange Act). Upon written request, certification
of the disposition of all canceled Notes shall be delivered to the Company. The
Company may not issue new Notes to replace Notes that it has paid or that have
been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

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

Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except
as provided in the preceding sentence, provisions of this Indenture that apply
to Notes called for redemption or purchase also apply to portions of Notes
called for redemption or purchase.

Section 3.03 Notice of Redemption.

      Subject to the provisions of Section 3.09 hereof, at least 30 days but not
more than 60 days before a redemption date, the Company shall mail or cause to
be mailed, by first class mail, a notice of redemption to each Holder whose

notices may be mailed more than 60 days prior to a redemption date if the notice
is issued in connection with a defeasance of the Notes or a satisfaction and
discharge of this Indenture pursuant to Articles 8 or 12 hereof.

      The notice shall identify the Notes to be redeemed (including the CUSIP

      (a) the redemption date;

      (b) the redemption price;

      (c) if any Note is being redeemed in part, the portion of the principal

      At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
shall have delivered to the Trustee, at least 45 days prior to the redemption
date, an Officers' Certificate requesting that the Trustee give such notice and

preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

                                       49



      Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

Section 3.05 Deposit of Redemption or Purchase Price.

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

Section 3.06 Notes Redeemed or Purchased in Part.

      Upon surrender of a Note that is redeemed or purchased in part, the

Offer"), it shall follow the procedures specified below.

      The Asset Sale Offer shall be made to all Holders and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets. The Asset Sale Offer shall remain open for
a period of at least 20 Business Days following its commencement and not more
than 30 Business Days, except to the extent that a longer period is required by

pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than
the Offer Amount has been tendered, all Notes and other Indebtedness tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased shall be
made in the same manner as interest payments are made.

      If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest and
Special Interest, if any, shall be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional

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

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

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

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

accepted for payment pursuant to the Asset Sale Offer will cease to accrue
interest after the Purchase Date;

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

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

      (g) that Holders will be entitled to withdraw their election if the
Company, the Depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

      (h) that, if the aggregate principal amount of Notes and other pari passu
Indebtedness surrendered by holders thereof exceeds the Offer Amount, the
Company shall select the Notes and other pari passu Indebtedness to be purchased
on a pro rata basis based on the principal amount of Notes and such other pari
passu Indebtedness surrendered (with such adjustments as may be deemed
appropriate by the Company so that only Notes in denominations of $2,000, or
integral multiples of $1,000, will be purchased); and

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

      On or before the Purchase Date, the Company 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 or cause to be delivered to the Trustee the Notes properly
accepted together with an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Company in 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 written request from the Company, shall authenticate and mail or
deliver (or cause

                                       52


to be transferred by book entry) such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered. Any Note not so
accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company 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.

            (4) make any Restricted Investment

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

      unless, at the time of and after giving effect to such Restricted Payment:

            (1) no Default or Event of Default has occurred and is continuing or
      would occur as a consequence of such Restricted Payment;

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

            (3) such Restricted Payment, together with the aggregate amount of
      all other Restricted Payments made by the Company and its Restricted
      Subsidiaries since the date of this Indenture (excluding Restricted
      Payments permitted by clauses (2), (3), (4), (5), (7) and (9) of paragraph
      (b) of this Section 4.07), is less than the sum, without duplication, of:

                  (A) 50% of the Consolidated Net Income of the Company for the
            period (taken as one accounting period) from the beginning of the
            first fiscal quarter commencing after the date of this Indenture to
            the end of the Company's most recently ended fiscal quarter for
            which internal financial statements are available at the time of
            such Restricted Payment (or, if such Consolidated Net Income for
            such period is a deficit, less 100% of such deficit); plus

                  (B) 100% of the aggregate net proceeds received by the Company
            since the date of this Indenture as a contribution to its common
            equity capital or from the issue or sale of Equity Interests of the
            Company (other than Disqualified Stock) or from the issue or sale of
            convertible or exchangeable Disqualified Stock or convertible or
            exchangeable debt securities of the Company that have been converted
            into or exchanged for such Equity Interests (other than Equity
            Interests (or Disqualified Stock or debt securities) sold to a
            Subsidiary of the Company); plus

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

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

                                       56


            Market Value as of the date on which such Subsidiary was originally
            designated as an Unrestricted Subsidiary after the date of this
            Indenture; plus

                  (E) 100% of any dividends received by the Company or a
            Restricted Subsidiary of the Company after the date of this
            Indenture from an Unrestricted Subsidiary of the Company, to the
            extent that such dividends were not otherwise included in the
            Consolidated Net Income of the Company for such period.

      (b) The provisions of Section 4.07(a) hereof shall not prohibit:

            (1) the payment of any dividend or the consummation of any
      irrevocable redemption within 60 days after the date of declaration of the
      dividend or giving of the redemption notice, as the case may be, if at the
      date of declaration or notice, the dividend or redemption payment would
      have complied with the provisions of this Indenture;

            (2) the making of any Restricted Payment in exchange for, or out of
      the net cash proceeds of the substantially concurrent sale (other than to
      a Subsidiary of the Company) of, Equity Interests of the Company (other
      than Disqualified Stock) or from the substantially concurrent contribution
      of common equity capital to the Company; provided that the amount of any
      such net cash proceeds that are utilized for any such Restricted Payment
      shall be excluded from clause (3)(B) of Section 4.07(a) hereof;

            (3) the repurchase, redemption, defeasance or other acquisition or
      retirement for value of the Company's 9-7/8% Senior Subordinated Notes due
      2007 with the net proceeds of this offer of the Notes and Indebtedness
      under the Credit Facilities;

            (4) the repurchase, redemption, defeasance or other acquisition or
      retirement for value of any Indebtedness of the Company or any Guarantor

      (in addition to that referred to in clause (3) above) with the net cash
      proceeds from a substantially concurrent incurrence of Permitted
      Refinancing Indebtedness;

            (5) so long as no Default has occurred and is continuing or would be
      caused thereby, the payment of any dividend (or, in the case of any

      Restricted Subsidiary of the Company to the holders of its Equity
      Interests on a pro rata basis;

            (6) so long as no Default has occurred and is continuing or would be

      Subsidiaries pursuant to any equity subscription agreement, stock option
      agreement, shareholders' agreement or similar agreement; provided that the
      aggregate price paid for all such repurchased, redeemed, acquired or
      retired Equity Interests may not exceed $2.0 million in any twelve-month
      period;

            (7) so long as no Default has occurred and is continuing or would be

      be caused thereby, other Restricted Payments in an aggregate amount not to
      exceed $15.0 million since the date of this Indenture.

      The amount of all Restricted Payments (other than cash) will be the Fair
Market Value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair
Market Value of any assets or securities that are required to be valued by this
Section 4.07 will be determined by the Board of Directors of the Company whose
resolution with respect thereto will be delivered to the Trustee. The Board of
Directors' determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
Fair Market Value exceeds $25.0 million.

Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries.

      (a) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any

      Indenture and any amendments, restatements, modifications, renewals,
      supplements, refundings, replacements or refinancings of those agreements;
      provided that the amendments, restatements, modifications, renewals,
      supplements, refundings, replacements or refinancings are not materially
      more restrictive, taken as a whole, with respect to such dividend and
      other payment restrictions than those contained in those agreements on the

            (2) this Indenture, the Notes and the Note Guarantees;

            (3) applicable law, rule, regulation or order;

                                       58


      to the extent such Indebtedness or Capital Stock 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, or the property
      or assets of the Person, so acquired; provided that, in the case of
      Indebtedness, such Indebtedness was permitted by the terms of this
      Indenture to be incurred;

            (5) customary non-assignment provisions in contracts and licenses

      Subsidiary that restricts distributions by that Restricted Subsidiary
      pending the sale or other disposition;

            (8) Permitted Refinancing Indebtedness; provided that the
      restrictions contained in the agreements governing such Permitted

      whole, than those contained in the agreements governing the Indebtedness
      being refinanced;

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

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

      (a) 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 Disqualified Stock, and the Guarantors may incur
Indebtedness (including Acquired Debt) or issue preferred stock, if the Fixed
Charge Coverage Ratio for the Company's most recently ended four full fiscal
quarters for which internal financial statements are available immediately
preceding the date on which such additional Indebtedness is incurred or such

                                       59


Disqualified Stock or such preferred stock is issued, as the case may be, would
have been at least 2.5 to 1, determined on a pro forma basis (including a pro
forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the Disqualified Stock or the preferred stock
had been issued, as the case may be, at the beginning of such four-quarter
period.

      (b) The provisions of Section 4.09(a) hereof shall not prohibit the
incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):

            (1) the incurrence by the Company and any Guarantor of additional
      Indebtedness and letters of credit under Credit Facilities in an aggregate
      principal amount at any one time outstanding under this clause (1) (with
      letters of credit being deemed to have a principal amount equal to the
      maximum potential liability of the Company and its Restricted Subsidiaries
      thereunder) not to exceed:

                  (A) prior to July 7, 2008, the greater of (i) $170.0 million
            less the aggregate amount of all Net Proceeds of Asset Sales applied
            by the Company or any of its Restricted Subsidiaries since the date
            of this Indenture to repay any term Indebtedness under a Credit
            Facility or to repay any revolving credit Indebtedness under a
            Credit Facility and effect a corresponding commitment reduction
            thereunder pursuant to Section 4.10 hereof less any amount that is
            released by the Hedge Counterparty under the Hedge Letter of Credit
            and (ii) 30% of ACNTA as of the date of such incurrence; and

                  (B) on or after July 7, 2008, the greater of (i) $130.0
            million less the aggregate amount of all Net Proceeds of Asset Sales
            applied by the Company or any of its Restricted Subsidiaries since
            the date of this Indenture to repay any term Indebtedness under a
            Credit Facility or to repay any revolving credit Indebtedness under
            a Credit Facility and effect a corresponding commitment reduction
            thereunder pursuant to Section 4.10 hereof less any amount that is
            released by the Hedge Counterparty under the Hedge Letter of Credit
            and (ii) 30% of ACNTA as of the date of such incurrence less $40.0
            million; provided that such amounts in the foregoing clauses (i) and
            (ii) of this paragraph shall be reduced by an additional $10.0
            million on each of the fifth, sixth and seventh anniversaries of the
            date of this Indenture;

            (2) the incurrence by the Company and any Guarantor of Indebtedness
      under the Hedge Agreement;

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

            (4) the incurrence by the Company and the Guarantors of Indebtedness
      represented by the Notes and the related Note Guarantees to be issued on
      the date of this Indenture and the Exchange Notes and the related Note
      Guarantees to be issued pursuant to the Registration Rights Agreement;

            (5) the incurrence by the Company or any of its Restricted
      Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
      net proceeds of which are used to renew, refund, refinance, replace,
      defease or discharge any Indebtedness (other than intercompany
      Indebtedness) that was permitted by this Indenture to be incurred under
      Section 4.09(a) hereof or clauses (3), (4), (5) or (14) of this Section
      4.09(b);

                                       60


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

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

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

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

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

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

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

            (8) the incurrence by the Company or any of its Restricted
      Subsidiaries of Hedging Obligations in the ordinary course of business
      (other than pursuant to the Hedge Agreement);

            (9) the guarantee by the Company or any of the Guarantors of
      Indebtedness of the Company or a Restricted Subsidiary of the Company that
      was permitted to be incurred by another provision of this Section 4.09;
      provided that if the Indebtedness being guaranteed is subordinated to or
      pari passu with the Notes, then the Guarantee shall be subordinated or
      pari passu, as applicable, to the same extent as the Indebtedness
      guaranteed;

            (10) in-kind obligations relating to net oil and natural gas
      balancing positions arising in the ordinary course of business;

            (11) any obligation arising from agreements of the Company or a
      Restricted Subsidiary of the Company providing for indemnification,
      guarantee, adjustment of purchase price, holdback, contingency payment
      obligations based on the performance of the acquired or disposed asset or
      similar obligations, in each case, incurred or assumed in connection with
      the acquisition or disposition of any business, asset or Capital Stock of
      a Restricted Subsidiary of the Company;

                                       61


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

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

            (14) the incurrence by the Company or any of the Guarantors of
      additional Indebtedness in an aggregate principal amount (or accreted
      value, as applicable) at any time outstanding, including all Permitted
      Refinancing Indebtedness incurred to renew, refund, refinance, replace,
      defease or discharge any Indebtedness incurred pursuant to this clause
      (14), not to exceed $25.0 million.

      The Company shall not incur, and shall not permit any Guarantor to incur,
any Indebtedness (including Permitted Debt) that is contractually subordinated
in right of payment to any other Indebtedness of the Company or such Guarantor
unless such Indebtedness is also contractually subordinated in right of payment
to the Notes and the applicable Note Guarantee on substantially identical terms;
provided, however, that no Indebtedness will be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Company solely
by virtue of being unsecured or by virtue of being secured on a first or junior
Lien basis.

      For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (14) above,
or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company
shall be permitted to classify such item of Indebtedness on the date of its
incurrence, or later reclassify all or a portion of such item of Indebtedness,
in any manner that complies with this Section 4.09. Indebtedness under Credit
Facilities outstanding on the date on which Notes are first issued and
authenticated under this Indenture will initially be deemed to have been
incurred on such date in reliance on the exception provided by clause (1) of the
definition of Permitted Debt. The accrual of interest, the accretion or
amortization of original issue discount, the payment of interest on any
Indebtedness in the form of additional Indebtedness with the same terms, the
reclassification of preferred stock as Indebtedness due to a change in
accounting principles, and the payment of dividends on Disqualified Stock in the
form of additional shares of the same class of Disqualified Stock shall not be
deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock
for purposes of this Section 4.09; provided, in each such case, that the amount
of any such accrual, accretion or payment is included in Fixed Charges of the
Company as accrued. The amount of any premium payable on Indebtedness upon the
prepayment, redemption or other retirement for value of such Indebtedness shall
be disregarded in determining the amount of such Indebtedness. Notwithstanding
any other provision of this Section 4.09, the maximum amount of Indebtedness
that the Company or any Restricted Subsidiary may incur pursuant to this Section
4.09 shall not be deemed to be exceeded solely as a result of fluctuations in
exchange rates or currency values.

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

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

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

                                       62


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

                  (A) the Fair Market Value of such assets at the date of
            determination; and

                  (B) the amount of the Indebtedness of the other Person.

Section 4.10 Asset Sales.

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

            (1) the Company (or the Restricted Subsidiary, as the case may be)
      receives consideration at the time of the Asset Sale at least equal to the
      Fair Market Value of the assets or Equity Interests issued or sold or
      otherwise disposed of; and

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

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

                  (B) any securities, Notes or other obligations received by the
            Company or any such Restricted Subsidiary from such transferee that
            are, within 90 days by the Company or such Restricted Subsidiary,
            converted by the Company or such Restricted Subsidiary into cash, to
            the extent of the cash received in that conversion; and

                  (C) any stock or assets of the kind referred to in Section
            4.10(b)(2) or (4) hereof.

      (b) Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, other than a Sale of Collateral, the Company (or the applicable Restricted
Subsidiary, as the case may be) may apply such Net Proceeds at its option:

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

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

            (3) to make a capital expenditure; or

            (4) to acquire other assets that are not classified as current
      assets under GAAP and that are used or useful in an Oil and Gas Business.

      (c) Within 360 days after the receipt of any Net Proceeds from an Asset
Sale that constitutes a Sale of Collateral or from a Casualty Event, the Company
(or the Restricted Subsidiary that owned those

                                       63


assets, as the case may be) may apply those Net Proceeds to purchase other
long-term assets that would constitute Collateral or to repay Priority Lien Debt
and, if such Priority Lien Debt is revolving credit Indebtedness, to
correspondingly reduce commitments with respect thereto.

      (d) Any Net Proceeds from Asset Sales or Casualty Events that are not
applied or invested as provided in Section 4.10(b) or (c) hereof shall
constitute "Excess Proceeds." If following such application or investment, the
percentage of the Company's expected production volumes hedged exceeds a range
to be agreed between the Hedge Counterparty and the Company at the time each
hedge transaction is consummated, then the Company shall terminate that portion
of the hedges necessary in order to have the volumes hedged be within such
range, and shall apply Excess Proceeds to effect such termination. When the
aggregate amount of Excess Proceeds not so applied exceeds $15.0 million, within
ten days thereof, the Company shall make an Asset Sale Offer to all Holders of
Notes and all holders of other Parity Lien Debt containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets in accordance with Section 3.09 hereof to
purchase the maximum principal amount of Notes and such other Parity Lien Debt
that may be purchased out of the Excess Proceeds. The offer price in any Asset
Sale Offer shall be equal to 100% of the principal amount plus accrued and
unpaid interest and Special Interest, if any, to the date of purchase and shall
be payable in cash. If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Company may use those Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of
Notes and other Parity Lien Debt tendered pursuant to such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and
such other Parity Lien Debt to be purchased on a pro rata basis. Upon completion
of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

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

Section 4.11 Transactions with Affiliates.

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

            (1) the Affiliate Transaction is on terms that are no less favorable
      to the Company or the relevant Restricted Subsidiary than those that would
      have been obtained in a comparable transaction by the Company or such
      Restricted Subsidiary with an unrelated Person; and

            (2) the Company delivers to the Trustee:

                  (A) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $5.0 million, a resolution of the Board of Directors of
            the Company set forth in an Officers' Certificate certifying that
            such Affiliate Transaction complies with this Section 4.11 and that
            such Affiliate

                                       64


            Transaction has been approved by a majority of the disinterested
            members of the Board of Directors, if any, of the Company; and

                  (B) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $15.0 million, an opinion as to the fairness to the
            Company or such Subsidiary of such Affiliate Transaction from a
            financial point of view issued by an accounting, appraisal or
            investment banking firm of national standing.

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

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

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

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

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

            (5) any issuance of Equity Interests (other than Disqualified Stock)
      of the Company to Affiliates of the Company;

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

            (7) payment of fees not in excess of $1.0 million per annum pursuant
      to the Management Agreement as in effect on the date of this Indenture,
      including any amendment or replacement agreement that is no more
      disadvantageous to the Holders of the Notes in any material respect than
      the original Management Agreement; provided that the amount of the fee
      shall not exceed $1.0 million per annum at any time;

            (8) payment of fees of $1,415,105, payable to Parent, upon the
      consummation of the Merger;

            (9) payment of fees not in excess of $5.9 million, payable to TPG
      Partners II L.P., upon the consummation of the Merger, pursuant to the
      Transaction Advisory Agreement as in effect on the date of this Indenture;

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

            (11) Permitted Payments to Parent (without duplication of amounts
      permitted pursuant to clause (7) above).

Section 4.12 Liens.

                                       65


      The Company shall not and shall not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind (other than Permitted Liens) securing
Indebtedness, Attributable Debt or trade payables upon any of their property or
assets, now owned or hereafter acquired, unless all payments due under this
Indenture and the Notes are secured on an equal and ratable basis with the
obligations so secured until such time as such obligations are no longer secured
by a Lien.

Section 4.13 Business Activities.

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

Section 4.14 Corporate Existence.

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

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

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

Section 4.15 Offer to Repurchase Upon Change of Control.

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

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

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

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

                                       66


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

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

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

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

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

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

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

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

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

      The Paying Agent will promptly mail (but in any case not later than five
days after the Change of Control Payment Date) to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any. The Company will publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Change of
Control Payment Date.

      (c) Notwithstanding anything to the contrary in this Section 4.15, the
Company will not be required to make a Change of Control Offer upon a Change of
Control if (1) a third party makes the Change of Control Offer in the manner, at
the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.09 hereof and purchases all Notes properly tendered
and not

                                       67


withdrawn under the Change of Control Offer, or (2) notice of redemption has
been given pursuant to Section 3.07 hereof, unless and until there is a default
in payment of the applicable redemption price.

Section 4.16 Payments for Consent.

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

Section 4.17 Additional Note Guarantees.

      If the Company or any of its Restricted Subsidiaries acquires or creates
another Domestic Subsidiary after the date of this Indenture, which Domestic
Subsidiary guarantees any Priority Lien Debt, then that newly acquired or
created Domestic Subsidiary shall become a Guarantor and execute a supplemental
indenture and deliver an Opinion of Counsel satisfactory to the Trustee and
deliver an Opinion of Counsel to the Trustee within 10 Business Days of the date
on which it was acquired or created to the effect that such supplemental
indenture has been duly authorized, executed and delivered by that Domestic
Subsidiary and constitutes a valid and binding agreement of that Domestic
Subsidiary, enforceable in accordance with its terms (subject to customary
exceptions); provided that any Domestic Subsidiary that constitutes an
Immaterial Subsidiary need not become a Guarantor until such time as it ceases
to be an Immaterial Subsidiary. The form of such Note Guarantee is attached as
Exhibit D hereto.

Section 4.18 Designation of Restricted and Unrestricted Subsidiaries.

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

      Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary shall be evidenced to the Trustee by filing with the Trustee a
certified copy of a resolution of the Board of Directors giving effect to such
designation and an Officers' Certificate certifying that such designation
complied with the preceding conditions and was permitted by Section 4.07. If, at
any time, any Unrestricted Subsidiary would fail to meet the preceding
requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of
such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary of the
Company as of such date and, if such Indebtedness is not permitted to be
incurred as of such date under Section 4.09, the Company shall be in default of
such covenant. The Board of Directors of the Company may at any time designate
any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company;
provided that such designation shall be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary, and such designation shall only be
permitted if

                                       68


(1) such Indebtedness is permitted under Section 4.09 calculated on a pro forma
basis as if such designation had occurred at the beginning of the four-quarter
reference period; and (2) no Default or Event of Default would be in existence
following such designation.

Section 4.19 Termination of Hedge Agreement.

      The Company shall not, and shall not permit any of the Guarantors to,
terminate the Hedge Agreement or the obligations thereunder during the term of
the Notes other than in connection with a partial termination in connection with
an Asset Sale or Casualty Event.

Section 4.20 Changes in Covenants When Notes Rated Investment Grade.

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

            (1) the Notes have an Investment Grade Rating; and

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

then, beginning on that day and subject to the provisions of the following
paragraph, the covenants under Sections 4.07, 4.08, 4.09, 4.10, 4.11 and
5.01(a)(4) shall be suspended.

      (b) Notwithstanding the foregoing, if the rating assigned by either such
rating agency should subsequently decline to below the Investment Grade Rating,
the foregoing covenants shall be reinstituted as of and from the date of such
rating decline. Calculations under the reinstated Section 4.07 shall be made as
if Section 4.07 had been in effect since the date of this Indenture except that
no default shall be deemed to have occurred solely by reason of a Restricted
Payment made while Section 4.07 was suspended.

                                    ARTICLE 5

Subsidiaries taken as a whole, in one or more related transactions, to another

      or existing under the laws of the United States, any state of the United
      States or the District of Columbia, or (ii) a partnership or limited
      liability company organized or existing under the laws of the United
      States, any state thereof or the District of Columbia that has at least
      one Restricted Subsidiary that is a corporation organized or existing
      under the laws of the United States, any state thereof or the District of
      Columbia, which corporation becomes a co-issuer of the Notes pursuant to a
      supplemental indenture duly and validly executed by the Trustee;

            (2) the Person formed by or surviving any such consolidation or
      merger (if other than the Company) or the Person to which such sale,
      assignment, transfer, conveyance or other disposition

                                       69


      has been made assumes all the obligations of the Company under the Notes,

      agreements reasonably satisfactory to the Trustee;

      Default exists;

            (4) the Company or the Person formed by or surviving any such
      consolidation or merger (if other than the Company), or to which such
      sale, assignment, transfer, conveyance or other disposition has been made
      would, on the date of such transaction after giving pro forma effect
      thereto and any related financing transactions as if the same had occurred
      at the beginning of the applicable four-quarter period, be permitted to
      incur at least $1.00 of additional Indebtedness pursuant to the Fixed
      Charge Coverage Ratio test set forth in Section 4.09(a) hereof, and

            (5) the Trustee shall have received an opinion of counsel
      satisfactory to the Trustee stating that the Parity Lien granted under the
      Security Documents on the Collateral to secure the Notes shall be an
      enforceable and perfected second-priority Lien after giving effect to such
      consolidation, merger, sale, assignment, transfer, conveyance or other
      disposition.

      In addition, the Company shall not, directly or indirectly, lease all or
substantially all of the properties and assets of it and its Restricted
Subsidiaries taken as a whole, in one or more related transactions, to any other
Person.

      (b) Section 5.01(a) shall not apply to:

            (1) a merger of the Company with an Affiliate solely for the purpose
      of reincorporating the Company in another jurisdiction; or

            (2) any consolidation or merger, or any sale, assignment, transfer,
      conveyance, lease or other disposition of assets between or among the
      Company and its Restricted Subsidiaries.

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
properties or assets of the Company in a transaction that is subject to, and
that complies with the provisions of, Section 5.01 hereof, the successor Person
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, assignment, transfer, lease, conveyance or
other disposition, the provisions of this Indenture referring to the "Company"
shall refer instead to the successor Person and not to the Company), and may
exercise every right and power of the Company under this Indenture with the same
effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the
obligation to pay the principal of and interest on the Notes except in the case
of a sale of all of the Company's assets in a transaction that is subject to,
and that complies with the provisions of, Section 5.01 hereof.

with Sections 4.07, 4.09, 4.10, 4.15 or 5.01 hereof;

      (d) failure by the Company or any of its Restricted Subsidiaries for 60
days after notice to the Company by the Trustee or the Holders of at least 25%
in aggregate principal amount of the Notes then outstanding voting as a single
class to comply with any of the other agreements in this Indenture or the
Security Documents;

      (e) default under any mortgage, indenture or instrument under which there
may be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company or any of its Restricted
Subsidiaries), including, without limitation, the Hedge Agreement, whether such
Indebtedness or Guarantee now exists, or is created after the date of this
Indenture, if that default:

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

            (2) results in the acceleration of such Indebtedness prior to its
      express maturity,

            and, in each case, the principal amount of any such Indebtedness,
      together with the principal amount of any other such Indebtedness under
      which there has been a Payment Default or the maturity of which has been
      so accelerated, aggregates $10.0 million or more;

      (f) failure by the Company or any of its Restricted Subsidiaries to pay
final judgments entered by a court or courts of competent jurisdiction
aggregating in excess of $10.0 million, which judgments are not paid, discharged
or stayed for a period of 60 days;

      (g) the occurrence of any of the following:

            (1) except as permitted by this Indenture, any security document
      ceases for any reason to be fully enforceable; provided, that it will not
      be an Event of Default under this clause (g)(1) if the sole result of the
      failure of one or more Security Documents to be fully enforceable is that
      any Parity Lien purported to be granted under such Security Documents on
      Collateral, individually or in the aggregate, having a Fair Market Value
      of not more than $10.0 million ceases to be an enforceable and perfected
      third-priority Lien, subject only to Permitted Prior Liens;

            (2) any Parity Lien purported to be granted under any security
      document on Collateral, individually or in the aggregate, having a Fair
      Market Value in excess of $10.0 million ceases to be an enforceable and
      perfected second-priority Lien, subject only to Permitted Prior Liens; or

            (3) the Company or any other Pledgor, or any Person acting on behalf
      of any of them, denies or disaffirms, in writing, any obligation of the
      Company or any other Pledgor set forth in or arising under any security
      document;

                                       71


      (h) except as permitted by this Indenture, any Note Guarantee is held in
any judicial proceeding to be unenforceable or invalid or ceases for any reason
to be in full force and effect, or any Guarantor, or any Person acting on behalf
of any Guarantor, denies or disaffirms its obligations under its Note Guarantee;

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

            (1) commences a voluntary case;

            (2) consents to the entry of an order for relief against it in an
      involuntary case;

            (3) consents to the appointment of a custodian of it or for all or
      substantially all of its property;

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

            (5) generally is not paying its debts as they become due; and

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

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

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

      Subsidiary or any group of Restricted Subsidiaries of the Company that,
      taken together, would constitute a Significant Subsidiary; or

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

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

Section 6.02 Acceleration.

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

      Upon any such declaration, the Notes shall become due and payable
immediately.

                                       72


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

Section 6.03 Other Remedies.

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

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

Section 6.04 Waiver of Past Defaults.

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

Section 6.05 Control by Majority.

      Holders of a majority in aggregate principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability.

Section 6.06 Limitation on Suits.

      Subject to Article 7, in case an Event of Default occurs and is
continuing, the Trustee shall be under no obligation to exercise any of the
rights or powers under this Indenture at the request or direction of any Holders
of Notes unless such Holders have offered to the Trustee reasonable indemnity or
security against any loss, liability or expense. Except to enforce the right to
receive payment of principal, premium, if any, or interest or Special Interest,
if any, when due, no Holder of a Note may pursue any remedy with respect to this
Indenture or the Notes unless:

      (a) such Holder gives to the Trustee written notice that an Event of
Default is continuing;

                                       73


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

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

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

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

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Special Interest,
if any, and interest on the Note, on or after the respective due dates expressed
in the Note (including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder; provided
that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution
thereof or the entry of judgment therein would, under applicable law, result in
the surrender, impairment, waiver or loss of the Lien of this Indenture upon any
property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.01(a) or (b) hereof occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as Trustee of an express trust against the Company for the whole amount of
principal of, premium and Special Interest, if any, and interest remaining
unpaid on, the Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

      The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and

                                       74


other properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

Section 6.10 Priorities.

      If the Trustee collects any money pursuant to this Article 6, to the
extent such money is not required to be paid to the Collateral Trustee for
application in accordance with the Collateral Trust Agreement, it shall pay out
the money in the following order:

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

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

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

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

Section 6.11 Undertaking for Costs.

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of
a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
aggregate principal amount of the then outstanding Notes.

                                    ARTICLE 7
                                     TRUSTEE

Section 7.01 Duties of Trustee.

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

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

            (1) the duties of the Trustee shall be determined solely by the
      express provisions of this Indenture and the Trustee need perform only
      those duties that are specifically set forth in this

                                       75


      Indenture and no others, and no implied covenants or obligations shall be
      read into this Indenture against the Trustee; and

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee shall examine the certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture.

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

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

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

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

      (d) Whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to paragraphs (a),
(b), and (c) of this Section 7.01.

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

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

      Section 7.02 Rights of Trustee.

      (a) The Trustee may conclusively rely upon any document believed by it to
be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

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

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

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

                                       76


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

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

      (g) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney
at the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation.

      (h) In no event shall the Trustee be responsible or liable for special,
indirect, or consequential loss or damage of any kind whatsoever (including, but
not limited to, loss of profit) irrespective of whether the Trustee has been
advised of the likelihood of such loss or damage and regardless of the form of
action.

      (i) The Trustee shall not be deemed to have notice of any Default or Event
of Default unless a Responsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default is
received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Securities and this Indenture.

      (j) The rights, privileges, protections, immunities and benefits given to
the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and each agent, custodian and other Person employed to act hereunder.

Section 7.03 Individual Rights of Trustee.

      The Trustee in its individual or any other capacity may become the owner
or pledgee of Notes and may otherwise deal with the Company or any Affiliate of
the Company with the same rights it would have if it were not Trustee. However,
in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as Trustee (if this Indenture has been qualified under the TIA) or
resign. Any Agent may do the same with like rights and duties. The Trustee is
also subject to Sections 7.10 and 7.11 hereof.

      The Trustee shall not be responsible for and makes no representation as to

Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults.

                                       77


      If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium or Special
Interest, if any, or interest on, any Note, the Trustee may withhold the notice
if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders of the
Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

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

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

Section 7.07 Compensation and Indemnity.

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

      (b) The Company and the Guarantors shall, jointly and severally, indemnify
the Trustee and any successor Trustee against any and all losses, damages,
claims, liabilities or expenses, including taxes (other than those based upon,
measured by or determined by the income of the Trustee), incurred by it arising
out of or in connection with the acceptance or administration of its duties
under this Indenture, including the costs and expenses of enforcing this
Indenture against the Company and the Guarantors (including this Section 7.07)
and defending itself against any claim (whether asserted by the Company, the
Guarantors, any Holder or any other Person) or liability in connection with the
exercise or performance of any of its powers or duties hereunder, except to the
extent any such loss, damage, claim, liability or expense may be attributable to
its negligence or bad faith. The Trustee shall notify the Company promptly of
any claim for which it may seek indemnity. Failure by the Trustee to so notify
the Company shall not relieve the Company or any of the Guarantors of their
obligations hereunder. The Company or such Guarantor shall defend the claim and
the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such
counsel. Neither the Company nor any Guarantor need pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

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

                                       78


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

      (e) When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

to the extent applicable.

the trust hereby created by so notifying the Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

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

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

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

office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

      (d) If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in aggregate principal amount of the then
outstanding Notes may petition any court of competent jurisdiction at the
expense of the Company (in the case of the Trustee) for the appointment of a
successor Trustee.

      (e) If the Trustee, after written request by any Holder who has been a

Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee; provided all sums owing to the

benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

substantially all of its corporate trust business to, another corporation, the

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02 Legal Defeasance and Discharge.

      Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company and each of the Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from their obligations with respect to all
outstanding Notes (including the Note Guarantees) and pursuant to Section 10.03
hereof, the Collateral Trustee's Liens upon the Collateral in respect of the
Notes shall be terminated and discharged, on the date the conditions set forth
below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal
Defeasance means that the Company and the Guarantors shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding Notes
(including the Note Guarantees), which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (1) and (2) below, and to have
satisfied all their other obligations under such Notes, the Note Guarantees and
this Indenture (and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following provisions which shall survive until otherwise terminated or
discharged hereunder:

                                       80


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

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

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

      (d) this Article 8.

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

Section 8.03 Covenant Defeasance.

      Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and each of the Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be released from each of their obligations under the covenants contained in
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19
and 4.20 hereof and clause (4) of Section 5.01 hereof with respect to the
outstanding Notes (including the Note Guarantees) and pursuant to Section 10.03
hereof, the Collateral Trustee's Liens upon the Collateral in respect of the
Notes shall be terminated and discharged, on and after the date the conditions
set forth in Section 8.04 hereof are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes and Note Guarantees, the Company and the Guarantors may omit
to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant (or such Note Guarantee), whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Company's exercise under Section
8.01 hereof of the option applicable to this Section 8.03, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(c) through 6.01(e) hereof shall not constitute Events of Default.

Section 8.04      Conditions to Legal or Covenant Defeasance.

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

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

                                       81


      (b) in the case of an election under Section 8.02 hereof, the Company must
deliver to the Trustee an Opinion of Counsel confirming that:

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

            (2) since the date of this Indenture, there has been a change in the
      applicable federal income tax law,

            in either case to the effect that, and based thereon such Opinion of
      Counsel shall confirm that, the Holders of the outstanding Notes shall not
      recognize income, gain or loss for federal income tax purposes as a result
      of such Legal Defeasance and shall be subject to federal income tax on the
      same amounts, in the same manner and at the same times as would have been
      the case if such Legal Defeasance had not occurred;

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

      (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) and the deposit shall
not result in a breach or violation of, or constitute a default under, any other
instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound;

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

      (g) the Company must deliver to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent 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

                                       82


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

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

      Notwithstanding anything in this Article 8 to the contrary, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(1) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium or Special
Interest, if any, or interest on, any Note and remaining unclaimed for two years
after such principal, premium or Special Interest, if any, or interest has
become due and payable shall be paid to the Company on its request or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Note shall thereafter be permitted to look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, 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 U.S. dollars or
non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the Guarantors' obligations under this
Indenture and the Notes and the Note Guarantees shall be revived and reinstated
as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 8.02 or 8.03 hereof, as the case may be; provided,
however, that, if the Company makes any payment of principal of, premium or
Special Interest, if any, or interest on, any Note following the reinstatement
of its obligations, the Company shall be subrogated to the rights of the Holders
of such Notes to receive such payment from the money held by the Trustee or
Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

                                       83


      Notwithstanding Section 9.02 of this Indenture, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the Notes
or the Note Guarantees without the consent of any Holder of 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 or a Guarantor's
obligations to the Holders of the Notes and Note Guarantees by a successor to
the Company or such Guarantor pursuant to Article 5 or Article 11 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;

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

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

      (g) to conform the text of this Indenture, the Note Guarantees, the
Security Documents and/or the Notes to any provision of the "Description of
Notes" section of the Company's Offering Circular dated July 1, 2004, relating
to the initial offering of the Notes, to the extent that such provision in that
"Description of Notes" was intended to be a verbatim recitation of a provision
of this Indenture, the Note Guarantees, the Security Documents or the Notes;

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

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

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

Section 9.02 With Consent of Holders of Notes.

      Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the
consent of the Holders of at least a majority in aggregate principal amount of
the then outstanding Notes (including, without limitation, Additional Notes, if
any) voting as a single class (including, without limitation, consents obtained
in connection with a tender offer or exchange offer for, or purchase of, the
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the

                                       84


principal of, premium or Special Interest, if any, or interest on, the Notes,
except a payment default resulting from an acceleration that has been rescinded)
or compliance with any provision of this Indenture or the Notes or the Note
Guarantees may be waived with the consent of the Holders of a majority in
aggregate principal amount of the then outstanding Notes (including, without
limitation, Additional Notes, if any) voting as a single class (including,
without limitation, consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall
determine which Notes are considered to be "outstanding" for purposes of this
Section 9.02.

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

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

      After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes or the Note Guarantees. However,
without the consent of each Holder affected, an amendment, supplement or waiver
under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder):

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

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

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

      (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 of, or interest or premium or Special Interest, if any, on, the
Notes;

                                       85


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

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

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

      In addition, any amendment to, or waiver of, the provisions of this
Indenture or any security document that has the effect of releasing any portion
of the Collateral from the Liens securing the Notes shall require the consent of
the Holders of at least 66-2/3% in aggregate principal amount of the Notes then
outstanding.

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and Effect of Consents.

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

Section 9.05 Notation on or Exchange of Notes.

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

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

Section 9.06 Trustee to Sign Amendments, etc.

      The Trustee shall sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amended or supplemental indenture until the Board of Directors
of the Company approves it. In executing any amended or supplemental indenture,
the Trustee shall receive and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section
13.04 hereof, an Officers' Certificate and an Opinion of Counsel stating that
the execution of such amended or supplemental indenture is authorized or
permitted by this Indenture.

Section 10.01 Equal and Ratable Sharing of Collateral by Holders of Parity Lien
Debt.

      Notwithstanding: (1) anything to the contrary contained in the Security
Documents; (2) the time of incurrence of any Series of Parity Lien Debt; (3) the
order or method of attachment or perfection of any Liens securing any Series of
Parity Lien Debt; (4) the time or order of filing or recording of financing
statements, mortgages or other documents filed or recorded to perfect any Lien
upon any Collateral; (5) the time of taking possession or control over any
Collateral; (6) that any Parity Lien may not have been perfected or may be or
have become subordinated, by equitable subordination or otherwise, to any other
Lien; or (7) the rules for determining priority under any law governing relative
priorities of Liens:

Pledgor shall secure, equally and ratably, all present and future Parity Lien
Obligations; and

      (b) all proceeds of all Parity Liens granted at any time by the Company or
any other Pledgor shall be allocated and distributed equally and ratably on
account of the Parity Lien Debt and other Parity Lien Obligations.

      The foregoing provision is intended for the benefit of, and shall be
enforceable as a third party beneficiary by, each present and future holder of
Parity Lien Obligations, each present and future Parity Lien Representative and
the Collateral Trustee as holder of Parity Liens. The Parity Lien Representative
of each future Series of Parity Lien Debt shall be required to deliver a Lien
Sharing and Priority Confirmation to the Collateral Trustee and the Trustee at
the time of incurrence of such Series of Parity Lien Debt.

enforceable as a third party beneficiary by, each present and future holder of
Priority Lien Obligations, each present and future Priority Lien Representative
and the Collateral Trustee as holder of the Priority Liens. No other Person

be required to deliver a Lien Sharing and Priority Confirmation to the
Collateral Trustee and each Priority Lien Representative at the time of
incurrence of such Series of Parity Lien Debt.

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

any Liens upon the Collateral are granted to secure any Priority Lien Debt or
the Hedge Agreement, then such liens shall also be granted to secure the Notes.

Section 10.04 Relative Rights.

      Nothing in the Note Documents shall:

      (a) impair, as between the Company and the Holders of the Notes, the

relating to reports, and TIA Section  314(d), relating to the release of
property or securities subject to the Lien of the Security Documents, to be
complied with. Any certificate or opinion required by TIA Section 314(d) may be
made by an Officer of the Company except in cases where TIA Section 314(d)
requires that such certificate or opinion be made by an independent Person,
which Person shall be an independent engineer, appraiser or other expert
selected by or reasonably satisfactory to the Trustee. Notwithstanding anything
to the contrary in this paragraph, the Company shall not be required to comply
with all or any portion of TIA Section 314(d) if it determines, in good faith
based on advice of counsel, that under the terms of TIA Section 314(d) and/or
any interpretation or guidance as to the meaning thereof of the SEC and its
staff, including "no action" letters or exemptive orders, all or any portion of
TIA Section 314(d) is inapplicable to one or a series of released Collateral.

Section 10.06 Further Assurances; Insurance.

      (a) The Company and each of the other Pledgors shall do or cause to be
done all acts and things that may be required, or that the Collateral Trustee
from time to time may reasonably request, to assure and confirm that the
Collateral Trustee holds, for the benefit of the holders of Secured Obligations,
duly created and enforceable and perfected Liens upon the Collateral (including
any property or assets that are acquired or otherwise become Collateral after
the Notes are issued), in each case, as contemplated by, and with the Lien
priority required under, the Secured Debt Documents.

      If the Company or any of the Pledgors acquires any material proved
producing Hydrocarbon Properties or develops any Hydrocarbon Properties that are
producing in commercial quantities, then the Company or such Pledgor shall, not
less than semi-annually, take all such actions and execute all documents that
the Collateral Trustee may reasonably request to create in favor of the
Collateral Trustee, for the benefit of the holders of the Secured Obligations,
valid and perfected security interests in such Hydrocarbon Properties.

      Upon the reasonable request of the Collateral Trustee or any Secured Debt
Representative at any time and from time to time, the Company and each of the
other Pledgors shall promptly execute, acknowledge and deliver such Security
Documents, instruments, certificates, notices and other documents, and take such
other actions as shall be reasonably required, or that the Collateral Trustee
may reasonably request, to create, perfect, protect, assure or enforce the Liens
and benefits intended to be conferred, in each case as contemplated by the
Secured Debt Documents for the benefit of the holders of Secured Obligations.

      (b) The Company and the other Pledgors shall:

            (1) keep their properties adequately insured at all times by
      financially sound and reputable insurers;

            (2) maintain such other insurance, to such extent and against such
      risks (and with such deductibles, retentions and exclusions), including
      fire and other risks insured against by extended coverage and coverage for
      acts of terrorism, as is customary with companies in the same or similar
      businesses operating in the same or similar locations, including public
      liability insurance against claims for personal injury or death or
      property damage occurring upon, in, about or in connection with the use of
      any properties owned, occupied or controlled by them;

            (3) maintain such other insurance as may be required by law; and

                                       89


            (4) maintain such other insurance as may be required by the Security
      Documents.

      (c) Upon the request of the Collateral Trustee, the Company and the other
Pledgors shall furnish to the Collateral Trustee full information as to their
property and liability insurance carriers. Holders of Secured Obligations, as a
class, shall be named as additional insureds, with a waiver of subrogation, on
all insurance policies of the Company and the other Pledgors and the Collateral
Trustee shall be named as loss payee, with 30 days' notice of cancellation or
material change, on all property and casualty insurance policies of the Company
and the other Pledgors.

                                   ARTICLE 11
                                 NOTE GUARANTEES

Section 11.01 Guarantee.

      (a) Subject to this Article 12, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees on a second-priority basis to each Holder
of a Note authenticated and delivered by the Trustee and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Notes or the obligations of the Company hereunder or thereunder,
that:

            (1) the principal, premium and Special Interest, if any, 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 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

            (2) 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 Guarantors shall be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

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

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

                                       90


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

Section 11.02 Limitation on Guarantor Liability.

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

Section 11.03 Execution and Delivery of Note Guarantee.

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

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

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

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

      In the event that the Company or any of its Restricted Subsidiaries
creates or acquires any Domestic Subsidiary after the date of this Indenture, if
required by Section 4.17 hereof, the Company shall cause such Domestic
Subsidiary to comply with the provisions of Section 4.17 hereof and this Article
11, to the extent applicable.

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

                                       91


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

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

      (b) either:

            (1) subject to Section 11.05 hereof, the Person acquiring the
      property in any such sale or disposition or the Person formed by or
      surviving any such consolidation or merger unconditionally assumes all the
      obligations of that Guarantor under this Indenture, its Note Guarantee and
      the Registration Rights Agreement on the terms set forth herein or
      therein, pursuant to a supplemental indenture in form and substance
      reasonably satisfactory to the Trustee; or

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

      In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the Note
Guarantee endorsed upon the Notes and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person shall succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. Such successor
Person thereupon may cause to be signed any or all of the Note 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 Note
Guarantees so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Note Guarantees theretofore and thereafter issued in
accordance with the terms of this Indenture as though all of such Note
Guarantees had been issued at the date of the execution hereof.

      Except as set forth in Articles 4 and 5 hereof, and notwithstanding
clauses (b)(1) and (b)(2) above, nothing contained in this Indenture or in any
of the Notes shall prevent any consolidation or merger of a Guarantor with or
into the Company or another Guarantor, or shall prevent any sale or conveyance
of the property of a Guarantor as an entirety or substantially as an entirety to
the Company or another Guarantor.

Section 11.05 Releases.

      (a) The Guarantee of a Guarantor shall be released:

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

                                       92


      the effect that such sale or other disposition was made by the Company in
      accordance with the provisions of this Indenture, including without
      limitation Section 4.10 hereof, the Trustee will execute any documents
      reasonably required in order to evidence the release of any Guarantor from
      its obligations under its Note Guarantee.

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

            (3) If any Guarantor is released from its Guarantee of Priority Lien
      Debt and the Hedge Agreement, such Guarantor will be released and relieved
      of any obligations under its Note Guarantee; provided, however, that if,
      at any time following such release, that Guarantor provides a Guarantee of
      any Priority Lien Debt or the Hedge Agreement, then such Guarantor shall
      be required to provide a Note Guarantee at such time.

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

      Any Guarantor not released from its obligations under its Note Guarantee
as provided in this Section 11.05 shall remain liable for the full amount of
principal of and interest and premium and Special Interest, if any, on the Notes
and for the other obligations of any Guarantor under this Indenture as provided
in this Article 11.

                                   ARTICLE 12

Section 12.01 Satisfaction and Discharge.

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

      (a) either:

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

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

      (b) no Default or Event of Default has occurred and is continuing on the
date of such deposit (other than a Default or Event of Default resulting from
the borrowing of funds to be applied to such deposit) and the deposit shall not
result in a breach or violation of, or constitute a default under, any other

                                       93


instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound;

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

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

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

      Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section 12.01, the provisions of Sections 11.02 and 8.06 hereof shall
survive. In addition, nothing in this Section 12.01 shall be deemed to discharge
those provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

Section 12.02 Application of Trust Money.

      Subject to the provisions of Section 8.06 hereof, all money deposited with
the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied
by it, in accordance with the provisions of the Notes and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium and Special Interest, if any)
and interest for whose payment such money has been deposited with the Trustee;
but such money need not be segregated from other funds except to the extent
required by law.

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

[Insert the Global Note Legend, if applicable, pursuant to the provisions of the
Indenture]

[Insert the Private Placement Legend, if applicable, pursuant to the provisions
of the Indenture]

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

            (1) INTEREST. Belden & Blake Corporation, an Ohio corporation (the
      "Company"), promises to pay interest on the principal amount of this Note
      at 8.75% per annum from July 7, 2004 until maturity and shall pay the
      Special Interest, if any, payable pursuant to Section 2 of the
      Registration Rights Agreement referred to below. The Company will pay
      interest and Special Interest, if any, semi-annually in arrears on January
      15 and July 15 of each year, or if any such day is not a Business Day, on
      the next succeeding Business Day (each, an "Interest Payment Date").
      Interest on the Notes will accrue from the most recent date to which
      interest has been paid or, if no interest has been paid, from the date of
      issuance; provided that if there is no existing Default in the payment of
      interest, and if this Note is authenticated between a record date referred
      to on the face hereof and the next succeeding Interest Payment Date,
      interest shall accrue from such next succeeding Interest Payment Date;
      provided further that the first Interest Payment Date shall be January 15,
      2005. The Company will pay interest (including post-petition interest in
      any proceeding under any Bankruptcy Law) on overdue principal and premium,
      if any, from time to time on demand at a rate that is 1% per annum in
      excess of the rate then in effect to the extent lawful; it will pay
      interest (including post-petition interest in any proceeding under any
      Bankruptcy Law) on overdue installments of interest and Special Interest,
      if any, (without regard to any applicable grace periods) from time to time
      on demand at the same rate to the extent lawful. Interest will be computed
      on the basis of a 360-day year of twelve 30-day months.

            (2) METHOD OF PAYMENT. The Company will pay interest on the Notes
      (except defaulted interest) and Special Interest, if any, to the Persons
      who are registered Holders of Notes at the close of business on the
      January 1 or July 1 next preceding the Interest Payment Date, even if such
      Notes are canceled after such record date and on or before such Interest
      Payment Date, except as provided in Section 2.12 of the Indenture with
      respect to defaulted interest. The Notes will be payable as to principal,
      premium and Special Interest, if any, and interest at the office or agency
      of the Company maintained for such purpose within or without the City and
      State of New York, or, at the option of the Company, payment of interest
      and Special Interest, if any, may be made by check mailed to the Holders
      at their addresses set forth in the register of Holders; provided that
      payment by wire transfer of immediately available funds will be required
      with respect to principal of and interest, premium and Special Interest,
      if any, on, all Global Notes and all other Notes the Holders of which will
      have provided wire transfer instructions to the Company or the Paying
      Agent. Such payment will be in such coin or currency of the United States
      of America as at the time of payment is legal tender for payment of public
      and private debts.

            (3) PAYING AGENT AND REGISTRAR. Initially, BNY Midwest Trust
      Company, the Trustee under the Indenture, will act as Paying Agent and
      Registrar. The Company may change any Paying Agent or Registrar without
      notice to any Holder. The Company or any of its Subsidiaries may act in
      any such capacity.

                                      A-2


            (4) INDENTURE. The Company issued the Notes under an Indenture dated
      as of July 7, 2004 (the "Indenture") among the Company, the Guarantors and
      the Trustee. The terms of the Notes include those stated in the Indenture
      and those made part of the Indenture by reference to the TIA. The Notes
      are subject to all such terms, and Holders are referred to the Indenture
      and such Act for a statement of such terms. To the extent any provision of
      this Note conflicts with the express provisions of the Indenture, the
      provisions of the Indenture shall govern and be controlling. The Notes are
      secured obligations of the Company. The Notes are secured by security
      interests in the Collateral pursuant to the Security Documents.

            (5) OPTIONAL REDEMPTION.

                  (a) Except as set forth in subparagraphs (b) and (c) of this
      Paragraph 5, the Company will not have the option to redeem the Notes
      prior to July 15, 2008. On or after July 15, 2008, the Company will have
      the option to redeem all or a part of the Notes upon not less than 30 nor
      more than 60 days' notice, at the redemption prices (expressed as
      percentages of principal amount) set forth below plus accrued and unpaid
      interest and Special Interest, if any, on the Notes redeemed to the
      applicable redemption date, if redeemed during the twelve-month period
      beginning on July 15 of the years indicated below, subject to the rights
      of Holders on the relevant record date to receive interest on the relevant
      interest payment date:



        Year                                Percentage
        ----                                ----------
                                         
2008...............................          104.375%
2009...............................          102.188%
2009 and thereafter................          100.000%


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

                  (b) Notwithstanding the provisions of subparagraph (a) of this
      Paragraph 5, at any time prior to July 15, 2007, the Company may on any
      one or more occasions redeem up to 35% of the aggregate principal amount
      of Notes (including any Additional Notes) issued under the Indenture at a
      redemption price of 108.750% of the principal amount, plus accrued and
      unpaid interest and Special Interest, if any, to the redemption date, with
      the net cash proceeds of an one or more Equity Offerings or a contribution
      to the Company's common equity capital made with the net cash proceeds of
      a concurrent offering of common stock of the Company's direct parent;
      provided that at least 65% in aggregate principal amount of the Notes
      (including any Additional Notes) issued under the Indenture (excluding
      Notes held by the Company and its Subsidiaries) remains outstanding
      immediately after the occurrence of such redemption and the redemption
      occurs within 60 days of the date of the closing of such Equity Offering
      or such contribution to the Company's common equity capital, as
      applicable.

                  (c) Notwithstanding the provisions of subparagraphs (a) or (b)
      of this Paragraph 5, at any time prior to July 15, 2008, the Company may
      also redeem all or a part of the Notes, upon not less than 30 nor more
      than 60 days' prior notice mailed by first-class mail to each Holder's
      registered address, at a redemption price equal to 100% of the principal
      amount of Notes redeemed plus the Applicable Premium as of, and accrued
      and unpaid interest and Special Interest, if any, to the date of
      redemption, subject to the rights of Holders of Notes on the relevant
      record date to receive interest due on the relevant interest payment date.

            (6) MANDATORY REDEMPTION.

                                      A-3


      The Company is not be required to make mandatory redemption or sinking
fund payments with respect to the Notes.

            (7) REPURCHASE AT THE OPTION OF HOLDER.

                  (a) If there is a Change of Control, the Company will be
      required to make an offer (a "Change of Control Offer") to each Holder to
      repurchase all or any part (equal to $1,000 or an integral multiple
      thereof) of each Holder's Notes at a purchase price in cash equal to 101%
      of the aggregate principal amount thereof plus accrued and unpaid interest
      and Special Interest, if any, thereon to the date of purchase, subject to
      the rights of Holders on the relevant record date to receive interest due
      on the relevant interest payment date (the "Change of Control Payment").
      Within 30 days following any Change of Control, the Company will mail a
      notice to each Holder setting forth the procedures governing the Change of
      Control Offer as required by the Indenture.

                  (b) Any Net Proceeds from Asset Sales or Casualty Events that
      are not applied or invested as described in Section 4.10 of the Indenture
      will constitute "Excess Proceeds." If following such application or
      investment, the percentage of the Company's expected production volumes
      hedged exceeds a range to be agreed between the Hedge Counterparty and the
      Company at the time each hedge transaction is consummated, then the
      Company shall terminate that portion of the hedges necessary in order to
      have the volumes hedged be within such range, and shall apply Excess
      Proceeds to effect such termination. When the aggregate amount of Excess
      Proceeds not so applied exceeds $15.0 million, within ten days thereof,
      the Company will make an Asset Sale Offer to all Holders of Notes and all
      holders of other Parity Lien Debt containing provisions similar to those
      set forth in the Indenture with respect to offers to purchase or redeem
      with the proceeds of sales of assets to purchase the maximum principal
      amount of Notes and such other Parity Lien Debt that may be purchased out
      of the Excess Proceeds. The offer price in any Asset Sale Offer will be
      equal to 100% of the principal amount plus accrued and unpaid interest and
      Special Interest, if any, to the date of purchase and will be payable in
      cash. If any Excess Proceeds remain after consummation of an Asset Sale
      Offer, the Company may use those Excess Proceeds for any purpose not
      otherwise prohibited by the Indenture. If the aggregate principal amount
      of Notes and other Parity Lien Debt tendered pursuant to such Asset Sale
      Offer exceeds the amount of Excess Proceeds, the Trustee will select the
      Notes and such other Parity Lien Debt to be purchased on a pro rata basis.
      Upon completion of each Asset Sale Offer, the amount of Excess Proceeds
      will be reset at zero. Holders of Notes that are the subject of an offer
      to purchase will receive an Asset Sale Offer from the Company prior to any
      related purchase date and may elect to have such Notes purchased by
      completing the form entitled "Option of Holder to Elect Purchase" attached
      hereto.

            (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address, except
      that redemption notices may be mailed more than 60 days prior to a
      redemption date if the notice is issued in connection with a defeasance of
      the Notes or a satisfaction or discharge of the Indenture. Notes in
      denominations larger than $1,000 may be redeemed in part but only in whole
      multiples of $1,000, unless all of the Notes held by a Holder are to be
      redeemed.

            (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
      form without coupons in denominations of $2,000 and integral multiples of
      $1,000. The transfer of Notes may be registered and Notes may be exchanged
      as provided in the Indenture. The Registrar and the Trustee may require a
      Holder, among other things, to furnish appropriate endorsements and
      transfer documents and the Company may require a Holder to pay any taxes
      and fees required by

                                      A-4


      law or permitted by the Indenture. The Company need not exchange or
      register the transfer of any Note or portion of a Note selected for
      redemption, except for the unredeemed portion of any Note being redeemed
      in part. Also, the Company need not exchange or register the transfer of
      any Notes for a period of 15 days before a selection of Notes to be
      redeemed or during the period between a record date and the corresponding
      Interest Payment Date.

            (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
      treated as its owner for all purposes.

            (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
      exceptions, the Indenture or the Notes or the Note Guarantees may be
      amended or supplemented with the consent of the Holders of at least a
      majority in aggregate principal amount of the then outstanding Notes
      including Additional Notes, if any, voting as a single class, and any
      existing Default or Event or Default or compliance with any provision of
      the Indenture or the Notes or the Note Guarantees may be waived with the
      consent of the Holders of a majority in aggregate principal amount of the
      then outstanding Notes including Additional Notes, if any, voting as a
      single class. Without the consent of any Holder of a Note, the Indenture
      or the Notes or the Note Guarantees may be amended or supplemented to cure
      any ambiguity, defect or inconsistency, to provide for uncertificated
      Notes in addition to or in place of certificated Notes, to provide for the
      assumption of the Company's or a Guarantor's obligations to Holders of the
      Notes and Note Guarantees in case of a merger or consolidation, to make
      any change that would provide any additional rights or benefits to the
      Holders of the Notes or that does not adversely affect the legal rights
      under the Indenture of any such Holder, to comply with the requirements of
      the SEC in order to effect or maintain the qualification of the Indenture
      under the TIA, to make, complete or confirm any grant of Collateral
      permitted or required by the Indenture or any of the Security Documents or
      any release of Collateral that becomes effective as set forth in the
      Indenture or any of the Security Documents, to conform the text of the
      Indenture, the Note Guarantees, the Security Documents and/or the Notes to
      any provision of the "Description of Notes" section of the Company's
      Offering Memorandum dated July 1, 2004, relating to the initial offering
      of the Notes, to the extent that such provision in that "Description of
      Notes" was intended to be a verbatim recitation of a provision of the
      Indenture, the Note Guarantees, the Security Documents or the Notes, to
      provide for the issuance of Additional Notes in accordance with the
      limitations set forth in the Indenture, or to allow any Guarantor to
      execute a supplemental indenture to the Indenture and/or a Note Guarantee
      with respect to the Notes.

      acceleration of the payment of such Indebtedness or failure to pay
      principal of, or interest or premium, if any, when due, subject to certain
      exceptions; (vi) one of more final judgments for the payment of money in

      any of its Restricted Subsidiaries that is a Significant Subsidiary or any

      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,
      all outstanding Notes will become due and payable immediately without
      further action or notice. Holders may not enforce the Indenture or the
      Notes except as provided in the Indenture. Subject to certain limitations,
      Holders of a majority in aggregate principal amount of the then
      outstanding Notes may direct the Trustee in its exercise of any trust or
      power. The Trustee may withhold from Holders of the Notes notice of any
      continuing Default or Event of Default (except a Default or Event of
      Default relating to the payment of principal or interest or premium or
      Special Interest, if any) if it determines that withholding notice is in
      their interest. The Holders of a majority in aggregate principal amount of
      the then outstanding Notes by notice to the Trustee may, on behalf of the
      Holders of all of the Notes, rescind an acceleration or 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 or Special Interest, if any, on, or the principal of, the
      Notes. The Company is required to deliver to the Trustee annually a
      statement regarding compliance with the Indenture, and the Company is
      required, upon becoming aware of any Default or Event of Default, to
      deliver to the Trustee a statement specifying such Default or Event of
      Default.

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

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

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

            (16) ABBREVIATIONS. Customary abbreviations may be used in the name
      of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN

                         FORM OF SUPPLEMENTAL INDENTURE
                    TO BE DELIVERED BY SUBSEQUENT GUARANTORS

      SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of
________________, 200__, among __________________ (the "Guaranteeing
Subsidiary"), a subsidiary of Belden & Blake Corporation (or its permitted
successor), an Ohio corporation (the "Company"), the Company, the other
Guarantors (as defined in the Indenture referred to herein) and BNY Midwest
Trust Company, as trustee under the Indenture referred to below (the "Trustee").

                               W I T N E S S E T H

      WHEREAS, the Company has heretofore executed and delivered to the Trustee
an indenture (the "Indenture"), dated as of July 7, 2004 providing for the
issuance of 8.75% Senior Secured Notes due 2012 (the "Notes");

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

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

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

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

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

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

      5.    NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

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

                                      E-1


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

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

                                      E-2


      IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.
