                                   ARTICLE I

                   DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.1       Definitions

     "144A Global Security" means a Global Security substantially in the form of
Exhibit A hereto bearing the Global Security Legend and the Private Placement
Legend and deposited with or on behalf of, and registered in the name of, the
Depositary or its nominee that will be issued in a denomination equal to the
outstanding principal amount of the Securities sold in reliance on Rule 144A.

                  "ACNTA" means (without duplication), as of the date of
determination:

     (1)  the sum of:

          (a)  discounted future net revenue from proved crude oil and natural
               gas reserves of the Company and its Restricted Subsidiaries
               calculated in accordance with SEC guidelines before any state or
               federal income taxes, as estimated in a reserve report prepared
               as of the end of the Company's most recently completed fiscal
               year, which reserve report is prepared or reviewed by independent
               petroleum engineers, as increased by, as of the date of
               determination, the discounted future net revenue of:

               (i)  estimated proved crude oil and natural gas reserves of the
                    Company and its Restricted Subsidiaries attributable to
                    acquisitions consummated since the date of such year-end
                    reserve report, and

               (ii) estimated crude oil and natural gas reserves of the Company
                    and its Restricted Subsidiaries attributable to extensions,
                    discoveries and other additions and upward determinations of
                    estimates of proved crude oil and natural gas reserves
                    (including previously estimated development costs incurred
                    during the period and the accretion of discount since the
                    prior year end) due to exploration,

<PAGE>

                    development or exploitation, production or other activities
                    which reserves were not reflected in such year-end reserve
                    report,

     in the case of the determination made under each of clauses (i) and (ii)
     above, calculated in accordance with SEC guidelines (utilizing the prices
     utilized in such year-end reserve report), and decreased by, as of the date
     of determination, the discounted future net revenue attributable to

               (iii) estimated proved crude oil and natural gas reserves of the
                    Company and its Restricted Subsidiaries reflected in such
                    year-end reserve report produced or disposed of since the
                    date of such year-end reserve report, and

               (iv) reductions in the estimated crude oil and natural gas
                    reserves of the Company and its Restricted Subsidiaries
                    reflected in such year-end reserve report since the date of
                    such year-end reserve report attributable to downward
                    determinations of estimates of proved crude oil and natural
                    gas reserves due to exploration, development or
                    exploitation, production or other activities conducted or
                    otherwise occurring since the date of such year-end reserve
                    report, in each case calculated in accordance with SEC
                    guidelines (utilizing the prices utilized in such year-end
                    reserve report);

               provided, however, that, in the case of each of the
               determinations made pursuant to clauses (i) through (iv), such
               increases and decreases shall be as estimated by the Company's
               engineers, except that if as a result of such acquisitions,
               dispositions, discoveries, extensions or revisions, there is a
               Material Change, then such increases and decreases in the
               discounted future net revenue shall be confirmed in writing by an
               independent petroleum engineer if the amount of ACNTA is required
               to be computed under this Indenture in connection with the
               calculation of clause (b)(1) of Section 4.3 hereof;

          (b)  the capitalized costs that are attributable to crude oil and
               natural gas properties of the Company and its Restricted
               Subsidiaries to which no proved crude oil and natural gas
               reserves are attributed, based on the Company's books and records
               as of a date no earlier than the date of the Company's latest
               annual or quarterly financial statements;

          (c)  the Net Working Capital on a date no earlier than the date of the
               Company's latest annual or quarterly financial statements; and

          (d)  the greater of (I) the net book value on a date no earlier than
               the date of the Company's latest annual or quarterly financial
               statements and (II) the appraised value, as estimated by
               independent appraisers within the immediately preceding 12
               months, of other tangible assets of the Company and its
               Restricted Subsidiaries (provided that the Company shall

                                       2
<PAGE>

               not be required to obtain such an appraisal of such assets if no
               such appraisal has been performed);

minus

(2)  to the extent not otherwise taken into account in the immediately preceding
     clause (1), the sum of:

               (a)  minority interests;

               (b)  any net gas balancing liabilities of the Company and its
                    Restricted Subsidiaries reflected in the Company's latest
                    audited financial statements;

               (c)  the discounted future net revenue, calculated in accordance
                    with SEC guidelines (utilizing the same prices utilized in
                    the Company's year-end reserve report), attributable to
                    reserves subject to participation interests, royalty
                    interests, overriding royalty interests, net profits
                    interests or other interests of third parties, pursuant to
                    participation, partnership, vendor financing or other
                    agreements then in effect, or which otherwise are required
                    to be delivered to third parties;

permitted to be incurred as of such date under Section 4.3 hereof, the Company
                                               -----------
shall be in default of such covenant.

                                      ---------

expressly agree to such terms and provisions and to be bound thereby. However,

New York, State of New York, as custodian for the Depositary, and registered in
the name of the Depositary or the nominee of the Depositary for the accounts of
designated agents holding on behalf of Euroclear or Clearstream, duly executed
by the Company and authenticated by the Trustee as hereinafter provided. Prior
to the expiration of the Restricted Period, any resale or transfer or such

Participants through Euroclear or Clearstream.

Section 2.2 Execution and Authentication

     Two Officers shall sign the Securities for the Company by manual or
facsimile signature. One Officer shall sign each Subsidiary Guarantee for each
Guarantor by manual or facsimile signature.

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

     A Security shall not be valid until an authorized signatory of the Trustee
manually authenticates the Security. The signature of the Trustee on a Security
shall be conclusive evidence that such Security has been duly and validly
authenticated and issued under this Indenture.

     The Trustee shall authenticate and deliver: (i) Initial Securities for
original issue in an aggregate principal amount of $175,000,000, (ii) if and
when issued, Additional Securities (which may be in the form of Initial
Securities or in the form of Exchange Securities) and (iii) Exchange Securities
for issue only in a registered exchange offer pursuant to the Registration
Rights Agreement, and only in exchange for Initial Securities or Additional
Securities of an equal principal amount, in each case upon a written order of
the Company signed by one Officer of the Company. Such order shall specify the
amount of the Securities to be authenticated and the date on which the original
issue of Securities is to be authenticated and whether the Securities are to be
in the form of Initial Securities or Exchange Securities. The Company may issue
Additional Securities under this Indenture subsequent to the Issue Date, subject
to Section 4.3 of this Indenture; provided, however, in no event may the Company
issue any Additional Securities if, as a result of any such issuance, the
aggregate principal amount of Securities outstanding would exceed the maximum
aggregate principal amount of Securities permitted under the Existing Credit
Facilities or any other Credit Facilities, in each case as in effect on the date
of such issuance.

                                       33
<PAGE>

         The Trustee may appoint an agent (the "Authenticating Agent")
reasonably acceptable to the Company to authenticate the Securities. Unless
limited by the terms of such appointment, any such Authenticating Agent may
authenticate Securities whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent.

Section 2.3 Registrar and Paying Agent

     The Company shall at all times maintain in the Borough of Manhattan, the
City of New York, the State of New York an office or agency where Securities may
be presented for registration of transfer or for exchange (the "Registrar") and
an office or agency where Securities may be presented for payment (the "Paying
Agent"). The Registrar shall keep a register of the Securities and of their
transfer and exchange. The Company may have one or more co-registrars and one or
more additional paying agents in the Borough of Manhattan, the City of New York,
the State of New York. The term "Registrar" includes any co-registrar, and the
term "Paying Agent" includes any such additional paying agent.

     The Company shall enter into an agreement with the initial Paying Agent and
initial Registrar evidencing its acceptance of its appointment as such in
accordance with the terms of this Indenture, which shall incorporate the terms
of the Trust Indenture Act, and the Company may enter into further agreements
with any of the Trustee, the initial Registrar and the initial Paying Agent with
respect to the allocation of responsibilities among them. The Company shall
enter into an appropriate agency agreement with any Registrar, Paying Agent or
co-registrar not a party to this Indenture, which shall incorporate the terms of
the Trust Indenture Act. The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee of the
name and address of each such agent not a party to this Indenture. If the
Company fails to maintain a Registrar or Paying Agent, the Trustee either shall
act as such in the designated corporate trust office of the Trustee in the
Borough of Manhattan, the City of New York, the State of New York, where the
Securities may be presented or surrendered for payment, in which case it shall
be entitled to appropriate compensation therefor pursuant to Section 7.7 hereof,
                                                             -----------
or the Trustee shall appoint or cause to be appointed such Registrar or Paying
Agent. The Company or any of its Subsidiaries may act as Paying Agent,
Registrar, co-registrar or transfer agent from an office in the Borough of
Manhattan, the City of New York, the State of New York. The Paying Agent or the
Registrar may resign as such upon 30 days' prior written notice to the Company
and the Trustee; upon resignation of any Paying Agent or Registrar, the Company
shall appoint a successor Paying Agent or Registrar, as the case may be,
complying with the requirements of this Section 2.3, no later than 30 days
                                        -----------
thereafter and shall provide notice to the Trustee of such successor Paying
Agent or Registrar.

     If at any time there shall be no Paying Agent with an office or agency in
the Borough of Manhattan, the City of New York, where the Securities may be
presented or surrendered for payment, the Company shall forthwith designate such
a Paying Agent in order that the Securities shall at all times be payable in the
Borough of Manhattan, the City of New York, the State of New York.

     The Company initially appoints The Bank of New York Trust Company, N.A. as
Registrar and Paying Agent for the Securities.

                                       34
<PAGE>

     The Bank of New York Trust Company, N.A. maintains an office in the Borough
of Manhattan, the City of New York, the State of New York, where Securities may
be presented or surrendered for payment which, on the Issue Date, is 101
Barclay, Lobby Level, New York, New York 10286.

Section 2.4 Paying Agent To Hold Money in Trust

     By at least 11:00 a.m. (New York City time) on the date on which any
principal, premium, if any, or interest on any Security is due and payable, the
Company shall deposit with the Paying Agent a sum sufficient to pay such
principal, premium, if any, and interest when due. The Company shall require
each Paying Agent (other than the Trustee) to agree in writing that such Paying
Agent shall hold in trust for the benefit of Holders or the Trustee all money
held by such Paying Agent for the payment of principal, premium, if any, and
interest (if any) on the Securities and shall notify the Trustee of any default
by the Company in making any such payment. If the Company or a Subsidiary acts
as Paying Agent, it shall segregate the money held by it as Paying Agent and
hold it as a separate trust fund. The Company at any time may require a Paying
Agent (other than the Trustee) to pay all money held by it to the Trustee and to
account for any funds disbursed by such Paying Agent. Upon complying with this
Section 2.4, the Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money delivered to the Trustee. Upon any
bankruptcy, reorganization or similar proceeding with respect to the Company,
the Trustee shall serve as Paying Agent for the Securities or, if it does not at
such time maintain an office in the Borough of Manhattan, the City of New York,
the State of New York, where Securities may be presented or surrendered for
payment, then it shall cause such a Paying Agent to be appointed.

Section 2.5 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
Holders. If the Trustee is not the Registrar, the Company shall furnish to the
Trustee, in writing 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 Holders.

          Procedures containing information regarding the Participant account to

          receipt by the Registrar of any certificates required pursuant to Rule

(h) Cancellation and/or Adjustment of Global Securities. At such time as all
beneficial interests in a particular Global Security have been exchanged for
Definitive Securities or a particular Global Security has been redeemed,
repurchased or canceled in whole and not in part, each such Global Security
shall be returned to or retained and canceled by the Trustee in accordance with
Section 2.10 hereof. At any time prior to such cancellation, if any beneficial
------------
interest in a Global Security is exchanged for or transferred to a Person who
will take delivery thereof in the form of a beneficial interest in another
Global Security or for Definitive Securities, the principal amount of Securities
represented by such Global Security shall be reduced accordingly and an
endorsement shall be made on such Global Security by the Registrar or by the
Depositary at the direction of the Registrar to reflect such reduction; and if
the beneficial interest is being exchanged for or transferred to a Person who
will take delivery thereof in the form of a beneficial interest in another
Global Security, such other Global Security shall be increased accordingly and
an endorsement shall be made on such Global Security by the Registrar or by the
Depositary at the direction of the Registrar to reflect such increase.

(i) General Provisions Relating to Transfers and Exchanges.

     (1) To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Global Securities and Definitive
Securities upon the Company's order or at the Registrar's request.

     (2) No service charge shall be made to a holder of a beneficial interest in
a Global Security or to a Holder of a Definitive Security for any registration
of transfer or exchange, but the Company may require payment of a sum sufficient
to cover any transfer tax or similar governmental charge or other fee required
by law and payable in connection therewith (other than any such transfer taxes
or similar governmental charge payable upon exchange or transfer pursuant to
Sections 2.9 , 3.6, 3.7, 4.7 and 4.11 hereof).
----------------------------     ----

     (3) The Registrar or co-registrar shall not be required to register the
transfer of or exchange of (A) any Definitive Security selected for redemption
in whole or in part pursuant to Article III hereof, except the unredeemed
                                -----------
portion of any Definitive Security being redeemed in part or (B) any Security
for a period beginning (1) 15 Business Days before the mailing of a notice of an
offer to repurchase or redeem Securities and ending at the close of business on
the day of such mailing or (2) 15 Business Days before an Interest Payment Date
and ending on such Interest Payment Date.

     (4) All Global Securities and Definitive Securities issued upon any
registration of transfer or exchange of Global Securities or Definitive
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Global
Securities or Definitive Securities surrendered upon such registration of
transfer or exchange.

     (5) None of the Company, the Trustee or the Registrar shall be required (A)
to issue, to register the transfer of or to exchange any Securities during a
period of 15 days before the day of any selection of Securities for redemption
under Section 3.2 hereof and ending at the close of business on the day of
      -----------
selection, (B) to register the transfer of or to exchange any Securities so

<PAGE>

Security being redeemed in part or (C) to register the transfer of or to
exchange a Security between a record date and the next succeeding Interest
Payment Date.

     (6) Prior to the due presentation for registration of transfer of any
Security, the Company, the Trustee, the Paying Agent, the Registrar or any
co-registrar may deem and treat the Person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal, interest and premium (if any) on such Security and for all
other purposes whatsoever, whether or not such Security is overdue, and none of
the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar
shall be affected by notice to the contrary.

Securities in accordance with the provisions of Section 2.2 hereof.

Section 2.7 Replacement Securities

     If any mutilated Security is surrendered to the Registrar or the Company
and the Registrar receives evidence to their satisfaction of the destruction,
loss or theft of any Security, the Company will issue and the Trustee, upon
receipt of a written order of the Company conforming to Section 2.2 hereof, will
                                                        -----------
authenticate a replacement Security if the Registrar's and the Company's
reasonable requirements are met. If required by the Registrar or the Company, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Registrar, the Trustee and the Company to protect the Company, the
Trustee, the Registrar, any other Agent and any Authenticating Agent from any
loss that any of them may suffer if a Security is replaced. The Company may
charge for its expenses in replacing a Security.

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

Section 2.8 Outstanding Securities

     The Securities outstanding at any time are all the Securities authenticated
by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee in accordance with the provisions hereof, and those described in
this Section as not outstanding. Except as set forth in Section 11.6 hereof, a
                                                        ------------
Security does not cease to be outstanding because the Company or an Affiliate of
the Company holds the Security.

     If a Security is replaced pursuant to Section 2.7 hereof, it ceases to be
                                           -----------
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a protected purchaser.

                                       49

<PAGE>

     If the principal  amount of any Security is  considered  paid under Section
                                                                         -------
4.1 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 Securities payable on that date, then on and after that date such
Securities will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.9 Temporary Securities

     Until Definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Securities. Temporary Securities
shall be substantially in the form of Definitive Securities but may have
variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate Definitive Securities in exchange for temporary Securities. Holders
of temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as a holder of Definitive Securities.

Section 2.10 Cancellation

     The Company at any time may deliver Securities to the Trustee or any
Registrar for cancellation. The Registrar and the Paying Agent shall forward to
the Trustee any Securities surrendered to them for registration of transfer,
exchange or payment. The Trustee or the Registrar and no one else shall cancel
and destroy (subject to the record retention requirements of the Exchange Act)
all Securities surrendered for registration of transfer, exchange, payment,
replacement or cancellation and deliver a certificate of such destruction to the
Company unless the Company directs the Trustee and the Registrar to deliver
canceled Securities to the Company. The Company may not issue new Securities to
replace Securities it has redeemed, paid or delivered to the Trustee or the
Registrar for cancellation.

Section 2.11 Defaulted Interest

     If the Company defaults in a payment of interest ("Defaulted Interest") on
the Securities, the Company shall pay Defaulted Interest (as provided in Section
                                                                         -------
4.1) in any lawful manner. The Company may pay the Defaulted Interest to the
---
Persons who are Holders on a subsequent special record date. The Company shall
fix or cause to be fixed (or upon the Company's failure to do so the Trustee
shall fix pursuant to a written instruction of Holders of at least a majority in
principal amount of the Securities) any such special record date and payment
date to the reasonable satisfaction of the Trustee which special record date
shall not be less than 10 days prior to the payment date for such Defaulted
Interest and the Company, or at the Company's request, the Trustee, shall
promptly mail or cause to be mailed to each Holder a notice that states the
special record date, the payment date and the amount of Defaulted Interest to be
paid. The Company shall notify the Trustee in writing of the amount of Defaulted
Interest proposed to be paid on each Security and the date of the proposed
payment, and at the same time the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of
such Defaulted Interest or shall make arrangements satisfactory to the Trustee
for such deposit prior to the date of the proposed payment, such money when so
deposited to be

                                       50
<PAGE>

held in trust for the benefit of the Persons entitled to such Defaulted Interest
as provided in this Section 2.11. Section 2.12 CUSIP Numbers
                    ------------

     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use) and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided, however, that any such
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

                                  ARTICLE III

                                   REDEMPTION

provided for in this Section 3.1 at least 60 days before the Redemption Date
                     -----------
unless the Trustee consents to a shorter period. Such notice shall be
accompanied by an Officers' Certificate to the effect that such redemption will
comply with the conditions herein. If fewer than all the Securities are to be
redeemed, the record date relating to such redemption shall be selected by the
Company and set forth in the related notice given to the Trustee, which record
date shall be not less than 15 days after the date of such notice.

Section 3.2 Selection of Securities To Be Redeemed

     In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities are
listed or, if the Securities are not listed, then on a pro rata basis and in
such manner as complies with applicable legal requirements. The Trustee shall
make the selection from outstanding Securities not previously called for
redemption. The Trustee may select for redemption portions of the principal of
Securities that have denominations larger than $1,000. Securities and portions
of them the Trustee selects shall be in amounts of $1,000 or a whole multiple of
$1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The
Trustee shall notify the Company promptly of the Securities or portions of
Securities to be redeemed. The Trustee may rely upon information provided by the
Registrar for purposes of this Section 3.2.
                               -----------

Section 3.3 Notice of Redemption

     At least 30 days but not more than 60 days before a date for redemption of
Securities, the Company shall mail a notice of redemption by first-class mail to
each Holder of Securities to be redeemed at such Holder's registered address.

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

     (1) the Redemption Date;

     (2) the Redemption Price;

     (3) the name and address of the Paying Agent where Securities are to be
surrendered;

     (4) that Securities called for redemption must be surrendered to the Paying
Agent to collect the Redemption Price;

     (5) if fewer than all the outstanding Securities are to be redeemed, the
identification and principal amounts of the particular Securities to be
redeemed;

     (6) that, unless the Company defaults in making such redemption payment,
interest on Securities (or portion thereof) called for redemption ceases to
accrue on and after the Redemption Date;

     (7) the CUSIP number, if any, printed on the Securities being redeemed; and

     (8) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Securities.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense. In such event, the Company
shall provide the Trustee with the information required by this Section 3.3.
                                                                -----------

Section 3.4 Effect of Notice of Redemption

     Once notice of redemption is mailed to Holders, Securities (or portions
thereof) called for redemption become irrevocably due and payable on the
Redemption Date and at the Redemption Price stated in the notice. A notice of
redemption may not be conditional. Upon surrender to the Paying Agent, such
Securities shall be paid at the Redemption Price stated in the notice, plus
accrued interest to the Redemption Date; provided that if the Redemption Date is
on or after a regular record date and on or prior to the Interest Payment Date,
the accrued and unpaid interest shall be payable to the Holder of the redeemed
Securities registered on the relevant record date. Failure to give notice or any
defect in the notice to any Holder shall not affect the validity of the notice
to any other Holder.

Section 3.5       Deposit of Redemption Price

         No later than 11:00 a.m. (New York City time) on the date on which any
principal, interest and premium (if any) on any Security is due and payable, the
Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary
is the Paying Agent, shall segregate and hold in trust) money sufficient to pay
the Redemption Price of and accrued interest on all Securities to be redeemed on
that date other than Securities or portions of Securities called for redemption
which are owned by the Company or a Subsidiary and have been delivered by the
Company or such Subsidiary to the Trustee for cancellation. If the Company
complies with the provisions of this paragraph, then on and after the Redemption
Date, interest will cease to accrue on the Securities or the portions of
Securities called for redemption.

Section 3.6 Securities Redeemed in Part

     Upon cancellation of a Security that is redeemed in part, the Company shall
issue and the Trustee shall authenticate for the Holder (at the Company's
expense) a new Security equal in principal amount to the unredeemed portion of
the Security surrendered. The Trustee shall notify the Registrar of the issuance
of such new Security.

                                                 ------------    ----
upon declaration or otherwise. Principal, premium, if any, and interest on the

Agent holds in accordance with this Indenture money sufficient to pay all
principal, premium, if any, and interest then due.

installments of interest (without regard to any applicable grace periods), from
time to time on demand at the same rate as on overdue principal.

     All references in this Indenture, the Securities or the Subsidiary
Guarantees to interest shall be deemed to include Additional Interest.

Section 4.2 SEC Reports

the Company will furnish to the Holders of Securities, within the time periods
specified in the SEC' s rules and regulations:

Subsidiaries, then the quarterly and annual financial information required by
the preceding paragraph shall include a reasonably detailed presentation, either
on the face of the financial statements or in the

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); provided, however, that the Company and any Guarantor may incur
Indebtedness (including Acquired Debt), 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 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 at the
beginning of such four-quarter period.

     (b) The foregoing paragraph (a) of this Section 4.3 will not prohibit the
                                             -----------
incurrence of any of the following items of Indebtedness (collectively,

less the aggregate amount of all permanent principal repayments since the Issue
Date under a Credit Facility that are made under clause (b)(1) of Section 4.7
                                                                  -----------

          (A) (i) if the Company is the obligor on such Indebtedness, such
     Indebtedness must be expressly subordinated to the prior payment in full in
     cash of all obligations with respect to the Notes, and (ii) if a Guarantor
     is the obligor of such Indebtedness, such Indebtedness must be expressly
     subordinated to the prior payment in full in cash of all obligations of
     such Guarantor with respect to its Subsidiary Guarantee, and

     Company or a Restricted Subsidiary thereof, shall be deemed, in each case,
     to constitute an incurrence of such Indebtedness by the Company or such

aggregate principal amount (or accrued value, as applicable) at any time
outstanding not to exceed $25.0 million.

     (c)  For purposes of determining compliance with this Section 4.3:
                                                           -----------
          (1) in the event that an item of proposed Indebtedness meets the
     criteria of more than one of the categories of Permitted Indebtedness
     described in clauses (1) through (13) of paragraph (b) above, or is
     entitled to be incurred pursuant to paragraph (a) of this Section 4.3, the
                                                               -----------
     Company will be permitted to classify such item of Indebtedness (or any
     portion thereof) on the date of its incurrence in any manner that complies
     with this covenant, and only be required to include the amount and type of
     such Indebtedness in one of such clauses;

          (2) all Indebtedness outstanding on the date of this Indenture under
     the Credit Facilities shall be deemed initially incurred on the Issue Date
     under clause (1) of paragraph (b) of this Section 4.3 and not paragraph (a)
     of this Section 4.3 or clause (2) of paragraph (b) of this Section 4.3;
             -----------                                        -----------

          (3) Guarantees of, or obligations in respect of letters of credit
     relating to, Indebtedness which is otherwise included in the determination
     of a particular amount of Indebtedness shall not be included;

          (4) if obligations in respect of letters of credit are incurred
     pursuant to the Credit Facility and are being treated as incurred pursuant
     to paragraph (b)(1) above and the letters of credit relate to other
     Indebtedness, then such other Indebtedness shall not be included;

          (5) Indebtedness permitted by this covenant need not be permitted
     solely by reference to one provision permitting such Indebtedness but may
     be permitted in part by one such provision and in part by one or more other
     provisions of this covenant permitting such Indebtedness;

          (6) the amount of Indebtedness issued at a price that is less than the
     principal amount thereof will be equal to the amount of the liability in
     respect thereof determined in accordance with GAAP; and

                                       57
<PAGE>

          (7) Indebtedness of any Person existing at the time such Person
     becomes a Restricted Subsidiary shall be deemed to have been incurred by
     the Company and the Restricted Subsidiary at the time such Person becomes a
     Restricted Subsidiary.

     (d) For purposes of determining compliance with any U.S. dollar-denominated
restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be
calculated based on the relevant currency exchange rate in effect on the date
such Indebtedness was incurred, in the case of term Indebtedness, or first
committed, in the case of revolving credit Indebtedness; provided that if such
Indebtedness is incurred to refinance other Indebtedness denominated in a
foreign currency, and such refinancing would cause the applicable U.S.
dollar-dominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such U.S.
dollar-dominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such refinancing Indebtedness does not exceed the
principal amount of such Indebtedness being refinanced. Notwithstanding any
other provision of this covenant, the maximum amount of Indebtedness that the
Company may incur pursuant to this covenant shall not be deemed to be exceeded
solely as a result of fluctuations in the exchange rate of currencies. The
principal amount of any Permitted Refinancing Indebtedness, if incurred in a
different currency from the Indebtedness being refinanced, shall be calculated
based on the currency exchange rate applicable to the currencies in which such
Permitted Refinancing Indebtedness is denominated that is in effect on the date
of such refinancing.

Section 4.4 Restricted Payments

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

          (1) declare or pay any dividend or make any other payment or

     in connection with any merger or consolidation involving the Company or any
     of its Restricted Subsidiaries) or to the direct or indirect holders of the
     Company's or any of its Restricted Subsidiaries' Equity Interests in their

     Interests (other than Disqualified Stock) of the Company or to the Company
     or a Restricted Subsidiary of the Company);

          (2) purchase, redeem or otherwise acquire or retire for value

     (other than any such Equity Interests owned by the Company or any
     Restricted Subsidiary of the Company);

          (3) make any payment on or with respect to, or purchase, redeem,
     defease or otherwise acquire or retire for value, prior to scheduled
     maturity or scheduled sinking fund payment, any Subordinated Indebtedness
     of the Company or any of its Restricted Subsidiaries, except a payment of
     interest or principal at the Stated Maturity thereof; or

                                       58
<PAGE>

          (4) make any Investment other than a Permitted Investment (all such
     payments and other actions set forth in clauses (1) through (3) above and
     this clause (4) being collectively referred to as "Restricted Payments"),

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

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

     (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 4.3(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
after the Issue Date (excluding Restricted Payments permitted by clauses (2),
(3), (4), (6), (7) and (9) of the next succeeding paragraph (c) below, but
including Restricted Payments permitted by clauses (1), (5) and (8) of such
paragraph), 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 full fiscal
     quarter during which the Issue Date falls to the end of the Company's most
     recently ended fiscal quarter for which internal financial statements are
     available at the time of such Restricted Payment (or, if such Consolidated
     Net Income for such period is a deficit, less 100% of such deficit), plus

          (B) 100% of the aggregate Net Cash Proceeds and 100% of the Fair
     Market Value of securities or other property other than cash (including
     Capital Stock of Persons engaged in the Oil and Gas Business that become
     Restricted Subsidiaries or assets used in the Oil and Gas Business)
     received by the Company since the Issue Date from the issue or sale of
     Equity Interests of the Company (other than Disqualified Stock), other than
     Equity Interests (or Disqualified Stock or debt securities) sold to a
     Subsidiary of the Company and other than an issuance or sale to an employee
     stock ownership plan or to a trust established by the Company or any of its
     Subsidiaries for the benefit of their employees, plus

          (C) the aggregate Net Cash Proceeds received by the Company subsequent
     to the Issue Date from the issue or sale of any Capital Stock of the
     Company (other than Disqualified Stock) to an Employee Stock Purchase
     Program; provided, however, that if an Employee Stock Purchase Program
     incurs any Indebtedness to finance the purchase of such Capital Stock, such
     aggregate amount will be limited to the excess of such Net Cash Proceeds
     over the amount of such Indebtedness plus an amount equal to any increase
     in the Consolidated Net Worth of the Company resulting from principal
     repayments made by an Employee Stock Purchase Program with respect to such
     Indebtedness; plus

                                       59
<PAGE>

          (D) the amount by which Indebtedness is reduced on the Company's
     consolidated balance sheet upon the conversion or exchange (other than by a
     Subsidiary of the Company) subsequent to the Issue Date of any Indebtedness
     convertible or exchangeable for Capital Stock (other than Disqualified
     Stock) of the Company (plus the amount of any accrued interest then
     outstanding on such Indebtedness to the extent the obligation to pay such
     interest is extinguished less the amount of any cash, or the fair market
     value of any property (as determined in good faith by an Officer of the
     Company), distributed by the Company upon such conversion or exchange);
     provided, however, that the foregoing amount shall not exceed the Net Cash
     Proceeds received by the Company or any Restricted Subsidiary from the sale
     of such Indebtedness (excluding Net Cash Proceeds from sales to a
     Subsidiary of the Company or to an employee stock ownership plan or to a
     trust established by the Company or any of its Subsidiaries for the benefit
     of their employees); plus

          (E) an amount equal to the sum of (i) the net reduction in the
     Investments (other than Permitted Investments) made by the Company or any
     Restricted Subsidiary in any Person resulting from repurchases, repayments
     or redemptions of such Investments by such Person, proceeds realized on the
     sale of such Investment and proceeds representing the return of capital
     (excluding dividends and distributions), in each case received by the
     Company or any Restricted Subsidiary, and (ii) to the extent such Person is
     an Unrestricted Subsidiary, the portion (proportionate to the Company's
     equity interest in such Subsidiary) of the Fair Market Value of the net
     assets of such Unrestricted Subsidiary at the time such Unrestricted
     Subsidiary is designated a Restricted Subsidiary; provided, however, that
     to the extent the foregoing sum exceeds, in the case of any such Person or
     Unrestricted Subsidiary, the amount of Investments (excluding Permitted
     Investments) previously made (and treated as a Restricted Payment) by the
     Company or any Restricted Subsidiary in such Person or Unrestricted
     Subsidiary, such excess shall not be included in this clause (E) unless the
     amount represented by such excess has not been and will not be taken into
     account in one of the foregoing clauses (A)-(D) of this paragraph (b)(3);
     plus

          (F) $10.0 million.

(c)  The preceding provisions will not prohibit:

     (1) the payment of any dividend within 60 days after the date of
declaration thereof, if at said date of declaration such payment would have
complied with the provisions of this Indenture (and such payment shall be deemed
to be paid on the date of payment for purposes of any calculation required by
this covenant);

     (2) the redemption, repurchase, retirement, defeasance or other acquisition
of any Subordinated Indebtedness of the Company or any Guarantor or of any
Equity Interests of the Company or any Restricted Subsidiary in exchange for, or

a Subsidiary of the Company) of, Equity Interests of the Company (other than
Disqualified Stock); provided that the amount of any such Net Cash Proceeds that
are utilized for any such redemption, repurchase, retirement, defeasance or
other acquisition shall be excluded from clause (3)(B) of the preceding
paragraph (b);

2002, the proceeds of which are used to purchase Capital Stock of the Company,
or to refinance loans or advances made pursuant to this clause (6), in an
aggregate amount not in excess of $1.0 million at any one time outstanding;

     (7) repurchases or other acquisitions for value of Capital Stock deemed to
occur upon the exercise or exchange of stock options, warrants or other
convertible securities if such Capital Stock represents a portion of the

connection with any such exercise or exchange; provided, however, that the
aggregate amount of such repurchases, redemption or acquisitions to satisfy
federal income tax obligations shall not exceed $2.0 million in any twelve-month

     The amount of all Restricted Payments (other than cash) shall be the Fair
Market Value on the date of the Restricted Payment of the asset(s) 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 at the
time of such Restricted Payment by this covenant shall be evidenced by an
Officers' Certificate to be delivered to the Trustee. Not later than five
Business Days following the date of the making of any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted, together with a copy of any related resolution
of the Board of Directors.

     For purposes of determining compliance with this Section 4.4, if a
                                                      -----------
Restricted Payment meets the criteria of more than one of the types of
Restricted Payments described in clauses (1)-(9) above, the Company, in its sole
discretion, may order and classify such Restricted Payment in any manner in
compliance with this covenant.

     In computing Consolidated Net Income under clause (b)(3)(A) above, (1) the
Company shall use audited financial statements for the portions of the relevant
period for which audited financial statements are available on the date of
determination and unaudited financial statements and other current financial
data based on the books and records of the Company for the remaining portion of
such period and (2) the Company shall be permitted to rely in good faith on the
financial statements and other financial data derived from the books and records
of the Company that are available on the date of determination.

Section 4.5 Liens

     The Company will not, and will not permit any of its Restricted
Subsidiaries to create, incur, assume or suffer to exist any Lien on any
property or asset now owned or hereafter acquired, or any income or profits
therefrom or assign or convey any right to receive income therefrom, except
Permitted Liens, to secure (a) any Indebtedness of the Company unless prior to,
or contemporaneously therewith, the Securities are equally and ratably secured
for so long as such other Indebtedness is so secured, or (b) any Indebtedness of
any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary
Guarantee of such Guarantor is equally and ratably secured for so long as such
other Indebtedness is so secured; provided, however, that if such Indebtedness
is expressly subordinated to the Securities or a Subsidiary Guarantee, the Lien
securing such Indebtedness will be subordinated and junior to the Lien securing
the Securities or such Subsidiary Guarantee, as the case may be, with the same
relative priority as such Indebtedness has with respect to the Securities or
such Subsidiary Guarantee.

Section 4.6 Dividend and Other Payment Restrictions Affecting Subsidiaries

     (a) The Company will not, and will 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
Restricted Subsidiary to:

          (1) pay dividends or make any other distributions on its Capital Stock
     to the Company or any of the Company's Restricted Subsidiaries, or pay any
     Indebtedness owed to the Company or any of the Company's Restricted
     Subsidiaries;

                                       62

Restricted Subsidiaries; or

     (3) transfer any of its properties or assets to the Company or any of the
Company's Restricted Subsidiaries.

restrictions existing under or by reason of:

Facilities as in effect on the Issue Date;

     (2) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at
the time of such acquisition (except to the extent such Indebtedness was
incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, 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 the Indenture to be incurred;

     (3) any agreement for the sale or other disposition of Capital Stock or
assets of a Restricted Subsidiary that restricts distributions by such
Restricted Subsidiary pending such sale or other disposition;

     (4) any amendment, restatement, modification, supplement, extension,
renewal, refunding, replacement or refinancing of Indebtedness referred to in
clauses (1) or (2) of this paragraph (b), provided that the encumbrances or
restrictions contained in the agreements governing the foregoing are no more
materially restrictive, taken as a whole, than those contained in the agreements
governing such Indebtedness;

     (5) restrictions on cash or other deposits by parties under agreements
entered into in the ordinary course of the Oil and Gas Business of the types
described in the definition of Permitted Business Investments; and

     (6) with respect to clause (3) of the preceding paragraph (a) only, any of
the following encumbrances or restrictions:

     ordinary course of business;

          (B) purchase money obligations for property acquired in the ordinary
     course of business that impose restrictions on the property so acquired;

          (C) Permitted Liens or Liens securing Indebtedness otherwise permitted
     to be incurred pursuant to the provisions of Section 4.5 hereof that limit
                                                  -----------
     the right of the Company or any of its Restricted Subsidiaries to dispose
     of the assets subject to such Lien;

                                       63

     definition of Permitted Business Investments.

Section 4.7 Asset Sales

     (a) The Company will not, and will 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 such Asset Sale at least equal to the Fair Market
Value of the Equity Interests or other assets issued or sold or otherwise
disposed of; and

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

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

          (B) any securities, notes or other obligations received by the Company
     or any such Restricted Subsidiary from such transferee that are converted
     within 120 days by the Company or such Restricted Subsidiary into cash (to
     the extent of the cash received in that conversion).

     (b) Within the later of (x) one year after the date of receipt of any Net
Proceeds from an Asset Sale and (y) six months after the date of an agreement
entered into within such one-year period committing the Company to make an
acquisition or expenditure referred to in clauses (2) or (3) below, the Company
may apply such Net Proceeds at its option, in any one or more of the following:

                                       64
<PAGE>

     (1) to permanently repay, prepay, redeem or repurchase the Senior Debt of
the Company or any Guarantor, and cause any related loan commitment to be
permanently reduced in an amount equal to the principal amount so repaid,
prepaid, redeemed or repurchased;

     (2) to acquire all or substantially all of the assets of, or a majority of
the Voting Stock of, a Company principally engaged in the Oil and Gas Business
or to acquire additional Capital Stock in any Person that at such time is a
Restricted Subsidiary; or

     (3) to make capital expenditures or to acquire properties or assets, in
each case that are used or useful in the Oil and Gas Business.

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

     (c) Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will make
an offer (the "Asset Sale Offer") to all Holders of Securities and, to the
extent required by the terms thereof, all holders of other Indebtedness that is
pari passu with the Securities containing provisions similar to those set forth
in this Indenture with respect to offers to purchase or redeem with the proceeds
of sales of assets to purchase the maximum principal amount of Securities and
such other pari passu Indebtedness that may be purchased out of the Excess
Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of
principal amount (or accreted value in the case of any such other pari passu
Indebtedness issued with a significant original issue discount) plus accrued and
unpaid interest, if any, to the date of purchase (the "Asset Sale Payment"), and
will be payable in cash. If any Excess Proceeds remain after consummation of an
Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of
Securities and such other pari passu Indebtedness tendered into such Asset Sale
Offer exceeds the amount of Excess Proceeds, the Trustee shall select the
Securities and such other pari passu Indebtedness to be purchased on a pro rata
basis, on the basis of the aggregate principal amounts (or accreted values)
tendered in round denominations (which in the case of the Securities will be
denominations of $1,000 principal amount or multiples thereof). Upon completion
of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

     (d) Within 30 days following the date when the Company becomes obligated to
make an Asset Sale Offer, the Company will mail a notice to each Holder
describing the transaction or transactions that constitute the Asset Sale and
offering to repurchase Securities on the date (the "Asset Sale Payment Date")
specified in such notice, which date will be no earlier than 30 days nor later
than 60 days from the date such notice is mailed, pursuant to the procedures
required by this Indenture and described in such notice.

     (e) On the Asset Sale Payment Date, the Company will, to the extent lawful:

          (1) accept for payment all Securities or portions thereof properly
     tendered pursuant to the Asset Sale Offer, subject to proration based on
     the amount of Excess Proceeds pursuant to clause (c) above of this Section
                                                                        -------
     4.7;
     ---

          (2) deposit with the Paying Agent an amount equal to the amount of
     Excess Proceeds that, after giving effect to proration with holders of pari
     passu Indebtedness pursuant to

                                       65
<PAGE>

     clause (c) above of this Section 4.7, is allocable to the Securities or
                              -----------
     portions thereof so tendered (or, if less, the aggregate Asset Sale Payment
     for all Securities validly tendered and not withdrawn); and

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

     (f) The Paying Agent will promptly mail to each Holder of Securities so
tendered and not withdrawn and accepted for payment in accordance with this
Section 4.7, the Asset Sale Payment for such tendered Securities, and the
-----------
Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to each Holder a new Security equal in principal amount to any
unpurchased portion of the Securities surrendered, if any, by such Holder;
provided that each such new Security will be in a principal amount of $1,000 or
an integral multiple thereof.

     (g) If the Asset Sale Offer Purchase Date is on or after an interest
payment record date and on or before the related Interest Payment Date, any
accrued and unpaid interest will be paid to the Person in whose name a Security
is registered at the close of business on such record date, and no other
interest will be payable to Holders who tender Securities pursuant to the Asset
Sale Offer.

     (h) The Company will comply with the requirements of Rule 14e-l under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with an Asset Sale
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Section 4.7, the Company will comply with
the applicable securities laws and regulations and will not be deemed to have
breached its obligations under this covenant by virtue of the Company's
compliance with such securities laws or regulations.

Section 4.8 Transactions With Affiliates

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

     (1) such 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 at the time of such transaction in arm's-length dealings by the
Company or such Restricted Subsidiary with a Person who is not an Affiliate; and

          (2) (A) with respect to any Affiliate Transaction or series of related
     Affiliate(s) Transactions involving aggregate consideration in excess of
     $5.0 million, a majority of the disinterested members of the Board of
     Directors have determined that the criteria set forth in clause (a)(1) of
     this Section 4.8 are satisfied with respect to such Affiliate
          -----------
     Transaction(s) and have approved such Affiliate Transaction(s), as
     evidenced by

                                       66
<PAGE>

     a Board Resolution delivered to the Trustee and certified by an Officers'
     Certificate as having been adopted by the Board of Directors; and

          (B) with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of $20.0
     million, the Company delivers to the Trustee a written opinion that such
     Affiliate Transaction(s) is fair, from a financial point of view, to the
     Company and its Restricted Subsidiaries, taken as a whole, or that such
     Affiliate Transaction(s), is not less favorable to the Company and its
     Restricted Subsidiaries than could reasonably be expected to be obtained at
     the time in an arm's-length transaction with a Person who is not an
     Affiliate, in either such case issued by an accounting, appraisal or
     investment banking firm of national standing that is not an Affiliate of
     the Company.

     (b) The following items shall not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.8(a) hereof:
                                                         -------------

     (1) any employment agreement or other employee compensation plan or
arrangement existing on the Issue Date or thereafter entered into by the Company
or any of its Restricted Subsidiaries in the ordinary course of business and
consistent with the past practice of the Company or such Restricted Subsidiary;

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

     (3) Investments (other than Permitted Investments) or Restricted Payments
that, in each case, are permitted by Section 4.4 hereof;
                                     -----------

     (4) loans or advances to employees, officers or directors in the ordinary
course of business of the Company or any of its Restricted Subsidiaries, in each
case only as permitted by Section 402 of the Sarbanes-Oxley Act of 2002, but in
any event not to exceed $1.0 million in the aggregate outstanding at any one
time;

     (5) indemnities of officers, directors and employees of the Company or any
Restricted Subsidiary consistent with applicable charter, bylaw or statutory
provisions; and

     (6) the payment of reasonable and customary fees to directors of the
Company or any of its Restricted Subsidiaries who are not employees of the
Company or any Subsidiary.

Section 4.9 Additional Subsidiary Guarantees

     If the Company or any of its Restricted Subsidiaries acquires or creates
another Restricted Subsidiary (other than Foreign Subsidiaries) after the Issue
Date, then the Company shall cause that newly acquired or created Restricted
Subsidiary to become a Guarantor and execute a supplemental indenture
substantially in the form of Exhibit E hereto and deliver an Opinion of Counsel
                             ---------
to the Trustee as provided in Section 11.4 of this Indenture.
                              ------------

Section 4.10 Business Activities

     The Company will not, and will not permit any Restricted Subsidiary to,
engage in any business other than the Oil and Gas Business, except to such
extent as would not be material in the opinion of the Board of Directors (which
opinion shall be reasonable and made in good faith) to the Company and its
Restricted Subsidiaries taken as a whole.

Section 4.11 Change of Control

     (a) If a Change of Control occurs, each Holder of Securities will have the
right to require the Company to repurchase all or any part (equal to $1,000 or
an integral multiple thereof) of that Holder's Securities pursuant to the offer
described below (the "Change of Control Offer"). In the Change of Control Offer,
the Company will offer a payment (the "Change of Control Payment") in cash equal
to 101% of the aggregate principal amount of Securities to be repurchased plus
accrued and unpaid interest thereon, if any, to the date of purchase. Within 30
days following any Change of Control, the Company will mail a notice to each
Holder describing the transaction or transactions that constitute the Change of
Control and offering to repurchase Securities on the date (the "Change of
Control Payment Date") specified in such notice, which date will be no earlier
than 30 days nor later than 60 days from the date such notice is mailed,
pursuant to the procedures required by this Indenture and described in such
notice. The Company will comply with the requirements of Rule 14e-l under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Securities as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of the covenant described herein, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under this covenant by virtue of the Company's
compliance with such securities laws or regulations.

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

     (1) accept for payment all Securities or portions thereof 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 Securities or portions thereof so tendered; and

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

     (c) The Paying Agent will promptly mail to each Holder of Securities so
tendered and not withdrawn the Change of Control Payment for such tendered
Securities, and the Trustee will promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Security equal in principal
amount to any unpurchased portion of the Securities surrendered, if any, by such
Holder; provided that each such new Security will be in a principal amount of
$1,000 or an integral multiple thereof. The Trustee will notify the Registrar of
the issuance of the new Security.

                                       68
<PAGE>

     (d) If the Change of Control Payment Date is on or after an interest
payment record date and on or before the related interest payment date, any
accrued and unpaid interest will be paid to the Person in whose name a Security
is registered at the close of business on such record date, and no other
interest will be payable to Holders who tender pursuant to the Change of Control
Offer.

     (e) 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.

     (f) The provisions described above that require the Company to make a
Change of Control Offer following a Change of Control will be applicable
regardless of whether or not any other provisions of this Indenture are
applicable.

     (g) The Company will not be required to make a Change of Control Offer upon
a Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Indenture applicable to a Change of Control Offer made by the Company
and purchases all Securities validly tendered and not withdrawn under such
Change of Control Offer.

Section 4.12 Maintenance of Office or Agency for Registration of Transfer,
     Exchange and Payment of Securities

     So long as any of the Securities shall remain outstanding, the Company

may be an office of the Trustee or an affiliate of the Trustee, or the
Registrar) in the Borough of Manhattan, the City of New York, State of New York,
where the Securities may be surrendered for exchange or registration of transfer
as in this Indenture provided, and where notices and demands to or upon the
Company in respect to the Securities may be served, and where the Securities may
be presented or surrendered for payment. The Company may also from time to time
designate one or more other offices or agencies in the Borough of Manhattan, the
City of New York, the State of New York, where Securities may be presented or
surrendered for any and all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in the Borough of Manhattan, the City of New York, State of New York for such
purposes. The Company will give to Trustee prompt written notice of the location
of any such office or agency and of any change of location thereof. The Company
initially appoints The Bank of New York Trust Company, N.A., as initial
Registrar and initial Paying Agent for each of said purposes. In case the
Company shall fail to maintain any such office or agency or shall fail to give
such notice of the location or of any change in the location thereof, such
surrenders, presentations and demands may be made and notices may be served at
the designated corporate trust office of the Trustee in the Borough of
Manhattan, City of New York, State of New York, and the Company hereby appoints
the Trustee its agent to receive at the aforesaid office all such surrenders,
presentations, notices and demands. The Trustee will give the Company prompt
notice of any change in location of the Trustee's designated corporate trust
office, but shall in all events maintain such an office in the Borough of
Manhattan, City of New York, State of New York.

specified in Section 6.1, upon the written request of the Trustee, deliver to

                              DEFAULTS AND REMEDIES

Section 6.1 Events of Default

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

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

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

     (3) failure by the Company to comply with Section 5.1 hereof or;
                                               -----------

     (4) failure by the Company or any of its Restricted Subsidiaries to comply
for 30 days after receipt of written notice specified below with Sections 4.2,
                                                                 -------- ---
4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 4.10 or 4.11 hereof;
---  ---  ---  ---  ---  ---  ---  ----    ----

     (5) failure by the Company for 60 days after receipt of written notice
specified below to comply with any of its other agreements contained in this
Indenture;

     (6) 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

<PAGE>

Guaranteed by the Company or any of its Restricted Subsidiaries), whether such
Indebtedness or Guarantee now exists, or is created after the date of this
Indenture, if that default:

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

          (B) results in the acceleration of such Indebtedness prior to its
     Stated 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
$5.0 million or more; provided, however, that if any such Payment Default is
cured or waived or any such acceleration rescinded, or such Indebtedness is
repaid, within a period of ten days from the continuation of such Payment
Default beyond the applicable grace period or the occurrence of such
acceleration, as the case may be, such Event of Default and any consequential
acceleration of the Notes shall be automatically rescinded, so long as such
rescission does not conflict with any judgment or decree;

          (7) failure by the Company or any of its Restricted Subsidiaries to
     pay final judgments aggregating in excess of $5.0 million (net of any
     amounts covered by insurance), which judgments are not paid, discharged or
     stayed for a period of 60 days;

          (8) any Subsidiary Guarantee of a Guarantor shall be held in any
     judicial proceeding to be unenforceable or invalid or, except as permitted
     by this Indenture, shall cease for any reason to be in full force and
     effect or any Guarantor, or any Person acting on behalf of any Guarantor,
     shall deny or disaffirm its obligations under its Subsidiary Guarantee, in
     each case with respect to any Guarantor that is also a Significant
     Subsidiary or any group of Guarantors that, taken together, would
     constitute a Significant Subsidiary; and

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

               (i) commences a voluntary case or proceeding;

               (ii) consents to the entry of an order for relief against it in
          an involuntary case or proceeding in which it is a debtor;

               (iii) consents to the appointment of a Custodian of it or for any
          substantial part of its property;

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

               (v) consents to the institution of a bankruptcy or an insolvency
          proceeding against it;

                                       74

<PAGE>

          or takes any comparable action under any foreign laws relating to
          insolvency; or

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

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

                    (ii) appoints a Custodian of the Company or any Significant
               Subsidiary or a group of Restricted Subsidiaries that, taken
               together, would constitute a Significant Subsidiary or for any
               substantial part of its property; or

                    (iii) orders the winding up or liquidation of the Company or
               any Significant Subsidiary or a group of Restricted Subsidiaries
               that, taken together would constitute a Significant Subsidiary;

         or any similar relief is granted under any foreign laws and the order,
         decree or relief remains unstayed and in effect for 60 consecutive
         days.

     However, a default under clauses (4) and (5) of this Section 6.1 will not
                                                          -----------
constitute an Event of Default until the Trustee or the Holders of 25% in
principal amount of the outstanding Securities notify the Company of the default
and the Company does not cure such default within the time specified in clauses
(4) and (5) of this Section 6.1 after receipt of such notice. Such notice must
                    -----------
specify the Default, demand that it be remedied and state that such notice is a
"Notice of Default."

Section 6.2 Acceleration of Maturity; Rescission and Annulment

     If an Event of Default (other than an Event of Default described in clause
(9) of Section 6.1) occurs and is continuing, the Trustee by notice to the
       -----------
Company, or the Holders of at least 25% in principal amount of the outstanding
Securities by notice to the Company and the Trustee, may declare the principal
of, premium, if any, and accrued and unpaid interest, if any, on all the
Securities to be due and payable. Upon such a declaration, such principal,
premium and accrued and unpaid interest will be due and payable immediately. If
an Event of Default described in clause (9) of Section 6.1 above occurs and is
                                               -----------
continuing, the principal of, premium, if any, and accrued and unpaid interest
on all the Securities will become and be immediately due and payable without any
further action or notice on the part of the Trustee or any Holders. The Holders
of a majority in outstanding principal amount of the Securities by notice to the
Trustee may on behalf of the Holders of all the Securities rescind any such
acceleration with respect to the Securities and its consequences if (1)
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction and (2) all existing Events of Default, other than the
nonpayment of the principal of, premium, if any, and interest on the Securities
that have become due solely by such declaration of acceleration, have been cured
or waived.

<PAGE>

Section 6.3 Other Remedies

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

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder 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. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by
law.

Section 6.4 Waiver of Past Defaults

     The Holders of a majority in outstanding principal amount of the
Securities, by notice to the Trustee may on behalf of the Holders of all the
Securities waive an existing Default or Event of Default and its consequences
hereunder except (i) a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on a Security or (ii) a Default or
Event of Default in respect of a provision that under Section 9.2 hereof cannot
                                                      -----------
be amended without the consent of each Holder affected. When a Default or Event
of Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any consequent right.

Section 6.5 Control by Majority

     The Holders of a majority in outstanding principal amount of the Securities
have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture or, subject to Section 7.1
                                                                   -----------
hereof, that the Trustee determines is unduly prejudicial to the rights of other
Holders or would involve the Trustee in personal liability; provided, however,
that the Trustee may take any other action deemed proper by the Trustee that is
not inconsistent with such direction. Subject to Section 7.1, prior to taking
                                                 -----------
any action hereunder, the Trustee shall be entitled to indemnification
reasonably satisfactory to it against all loss, liability and expense caused by
taking or not taking such action.

Section 6.6 Limitation on Suits

     Except to enforce the right to receive payment of principal, premium (if
any) or interest when due, a Holder may not pursue any remedy with respect to
this Indenture, the Securities or the Guarantees unless:

     (1) the Holder has previously given the Trustee written notice stating that
an Event of Default is continuing;

     (2) Holders of at least 25% in outstanding principal amount of the
Securities have made a written request to the Trustee to pursue the remedy;

                                       76
<PAGE>

     (3) such Holder or Holders have furnished the Trustee reasonable security
or indemnity against any loss, liability or expense;

     (4) the Trustee has not complied with the Holders' request within 60 days
after receipt of the request and the furnishing of security or indemnity; and

     (5) the Holders of a majority in outstanding principal amount of the
Securities have not given the Trustee a direction that, in the opinion of the
Trustee, is inconsistent with the request during such 60-day period.

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

Section 6.7 Rights of Holders to Receive Payment

     Notwithstanding any other provision of this Indenture, the right of any
Holder to receive payment of principal of, premium, if any, and interest on the
Securities held by such Holder, on or after the respective due dates expressed
in the Securities, or to bring suit for the enforcement of any such payment on
or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

Section 6.8 Collection Suit by Trustee

     If an Event of Default specified in Section 6.1(1) or Section 6.1(2) hereof
                                         --------------    --------------

                                -----------
expenses of collection, including the reasonable compensation, disbursement and
advances of the Trustee, its agents and counsel.

Section 6.9 Trustee May File Proofs of Claim

     The Trustee may 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 and the
Holders allowed in any judicial proceedings relative to the Company or any
Subsidiary Guarantor or their respective creditors or properties and, unless
prohibited by law or applicable regulations, may vote on behalf of the Holders
in any election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make 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 it for the compensation, expenses,
disbursements and advances of the Trustee, its agents and its counsel, and any
other amounts due the Trustee under Section 7.7 hereof.
                                    -----------

     and

          Third: to the Company.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10. At least 15 days before such record date,
                         ------------
the Trustee shall mail to each Holder and the Company a notice that states the
record date, the payment date and amount to be paid.

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
Trustee, a court in its discretion may require the filing by any party litigant

Section 7.1 Duties of Trustee

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise the rights and powers vested in it by this Indenture and use the

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: (i) the Trustee
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture and no implied covenants or obligations shall be read
into this Indenture against the Trustee; and (ii) in the absence of bad faith on
its part, the Trustee may conclusively rely, as to the truth of the statements
and the correctness 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.

                                       78
<PAGE>

     (c) The Trustee may not be relieved from liability for its own negligent

faith by a Trust Officer unless it is proved that the Trustee was negligent in
ascertaining the pertinent facts; and

omits to take in good faith in accordance with a direction received by it
pursuant to Section 6.5 hereof.

require the Trustee to expend or risk its own funds or otherwise incur financial

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
or resign. Any Paying Agent, Registrar, co-registrar or co-paying agent may do
the same with like rights. However, the Trustee must comply with Sections 7.10
                                                                 -------------

in the case of a Default or Event of Default relating to payment of principal
of, premium, if any, or interest on, any Security (including payments pursuant
to the optional redemption or required repurchase provisions of such Security,
if any), the Trustee may withhold the notice if and so long as its board of

collection, costs of preparing and reviewing reports, certificates and other
documents, costs of preparation and mailing of notices to Holders and reasonable
costs of counsel retained by the Trustee in connection with the delivery of an
Opinion of Counsel or otherwise, in addition to the compensation for its

asserted by any Holder, the Company or otherwise). The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. Failure by the
Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder. The Company shall defend the claim and the Trustee may
have separate counsel and the Company shall pay the fees and expenses of such
counsel. The Company is not required to reimburse any expense or indemnify
against any loss, liability claim, again, suit, cost or expense incurred by the
Trustee through the Trustee's own willful misconduct or negligence.

     (b) To secure the Company's payment obligations in this Section 7.7, the
                                                             -----------
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of, premium (if any) and interest on particular Securities.

     (c) The Company's payment obligations pursuant to this Section 7.7 shall
                                                            -----------
survive the discharge of this Indenture and the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.1(9) hereof with respect to the Company, the expenses are
             -------------
intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.8 Replacement of Trustee

     (a) A resignation or removal of the Trustee and appointment of a successor
Trustee will become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.8.
                                -----------

                                       81
<PAGE>

     (b) The Trustee may resign at any time by so notifying the Company. The
Holders of a majority in outstanding principal amount of the Securities may
remove the Trustee by so notifying the Trustee and the Company and may appoint a
successor Trustee. The Company may remove the Trustee if: (i) the Trustee fails
to comply with Section 7.10 hereof; (ii) the Trustee is adjudged bankrupt or
               ------------
insolvent; (iii) a Custodian or other public officer takes charge of the Trustee
or its property; or (iv) the Trustee otherwise becomes incapable of acting.

     (c) If the Trustee resigns or is removed by the Company or by the Holders
of a majority in outstanding principal amount of the Securities and such Holders
do not reasonably promptly appoint a successor Trustee, or if a vacancy exists
in the office of Trustee for any reason (the Trustee in such event being
referred to herein as the retiring Trustee), the Company shall promptly appoint
a successor Trustee.

     (d) A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to the Holders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.7 hereof.
                -----------

     (e) If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in outstanding principal amount of the Securities may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

     (f) If the Trustee fails to comply with Section 7.10 hereof after written
                                             ------------
notice thereto, the Holders of at least 10% in principal amount of the then
outstanding securities may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

     (g) Notwithstanding the replacement of the Trustee pursuant to this Section
                                                                         -------
7.8, the Company's obligations under Section 7.7 hereof shall continue for the
---                                  -----------
benefit of the retiring Trustee.

Section 7.9 Successor Trustee by Merger

     (a) If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation or banking association without any further act shall be the
successor Trustee.

     (b) If at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trusts created by this
Indenture, any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor Trustee, and deliver such Securities so
authenticated; and if at that time any of the Securities shall not have been
authenticated, any successor to the Trustee may authenticate such Securities
either in the name of any predecessor hereunder or in the name of the successor
to the Trustee; and in all such cases such certificates shall have the full
force which it is anywhere in the Securities or in this Indenture provided that
the certificate of the Trustee shall have.

Securities at maturity or the Redemption Date, as the case may be, then the
Trustee shall acknowledge satisfaction and discharge of this Indenture, and the
obligations of the Company and the Subsidiary Guarantors under the Securities
and the Subsidiary Guarantees, on demand of the Company (accompanied by an
Officers' Certificate and an Opinion of Counsel stating that all conditions
precedent specified herein relating to the satisfaction and discharge of this
Indenture have been complied with) and at the cost and expense of the Company.

     (b) Subject to Section 8.2 hereof, the Company at its option at any time
                    -----------
may terminate (i) all its obligations, subject to Section 8.1(c) hereof, under

the Securities and this Indenture and all obligations of the Guarantors with
respect to their Subsidiary Guarantees ("legal defeasance option"), and after
giving effect to such legal defeasance, any omission to comply with such
obligations shall no longer constitute a Default or Event of Default or (ii) its
obligations under Section 4.2, Section 4.3, Section 4.4, Section 4.5, Section
                  -----------   ----------  -----------  -----------  -------

                                       --------------------------
as specified above, the remainder of this Indenture and the Securities shall be
unaffected thereby. The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option. If the
Company exercises its legal defeasance option or its covenant defeasance option,
each Guarantor shall be released from its obligations with respect to its
Subsidiary Guarantee.

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

     (2) in the case of the legal defeasance option, the Company shall have
delivered to the Trustee an Opinion of Counsel reasonably acceptable to the
Trustee confirming that (a) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (b) since the Issue Date,
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 Securities will not recognize income, gain
or loss for federal income tax purposes as a result of such legal defeasance
option and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such legal
defeasance option had not occurred;

     (3) in the case of the covenant defeasance option, the Company shall have
delivered to the Trustee an Opinion of Counsel reasonably acceptable to the
Trustee confirming that the Holders of the outstanding Securities will not
recognize income, gain or loss for federal income tax purposes as a result of
such covenant defeasance option and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance option had not occurred;

     (4) no Default or Event of Default shall have occurred and be continuing
either: (a) on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit); or

concerned, at any time in the period ending on the 91st day after the date of
deposit;

     (5) such legal defeasance option or covenant defeasance option will not
result in a breach or violation of, or constitute a default under any material
agreement or instrument (other than this Indenture) to which the Company or any
of its Restricted Subsidiaries is a party or by which the Company or any of its
Restricted Subsidiaries is bound;

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

     (7) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders of

                                       85
<PAGE>

Securities over the other creditors of the Company with the intent of defeating,
hindering, delaying or defrauding creditors of the Company or others; and

and interest on the Securities.

Section 8.4 Repayment to Company

     The Trustee and the Paying Agent shall promptly turn over to the Company

     Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of principal of, or premium, if any, or interest on the Securities
that remains unclaimed for two years (or any such money then held by the Company
or any Subsidiary shall be discharged from any trust hereunder), and,
thereafter, Holders entitled to the money must look to the Company for payment
as unsecured general creditors; 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 will not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Company.

Section 8.5 Indemnity for Government Securities

     The Company shall pay and shall indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against deposited Government Securities
or the principal and interest received on such Government Securities.

Securities in accordance with this Article VIII 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
obligations of the Company under this Indenture and the Securities shall be

                                       86
<PAGE>

revived and reinstated as though no deposit had occurred pursuant to this
Article VIII until such time as the Trustee or Paying Agent is permitted to
apply all such money or Government Securities in accordance with this Article
VIII; provided, however, that, if the Company has made any payment of interest
on or principal of any Securities because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or Government Securities
held by the Trustee or Paying Agent.

that resulted from such acceleration);

     (5) make any Security payable in money other than that stated in the
Securities;

     (6) make any change in the provisions of the Indenture relating to waivers
of past Defaults or the rights of Holders of Securities to receive payments of
principal of or premium, if any, or interest on the Securities (except as

                                                         -----------
effective, the Company shall mail to each Holder of Securities affected thereby
a notice briefly describing such amendment. The failure to give such notice to
any or all Holders, or any defect therein, shall not impair or affect the
validity of any amendment, supplement or waiver under this Section 9.2.
                                                           -----------

Section 9.3 Compliance with Trust Indenture Act

     Every amendment to this Indenture, the Securities or the Subsidiary
Guarantees shall comply with the Trust Indenture Act as then in effect.

Section 9.4 Revocation and Effect of Consents and Waivers

     A consent to an amendment, supplement or waiver by a Holder of a Security
shall bind the Holder and every subsequent Holder of that Security or portion of
the Security that evidences the same debt as the consenting Holder's Security
(or any Holder of a Security issued upon the registration of transfer or
exchange thereof or in lieu thereof), even if notation of the amendment,
supplement or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent as to such Holder's Security or portion
of the Security if the Trustee receives the written notice of revocation before
the date the amendment, supplement or waiver becomes effective. After an
amendment, supplement or waiver becomes effective in accordance with its terms,
it shall bind every Holder.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to give their consent or take any
other action described above or required or permitted to be taken pursuant to
this Indenture. If a record date is fixed, then notwithstanding the immediately
preceding paragraph, those Persons who were Holders at the close of business on
such record date (or their duly designated proxies), and only those Persons,
shall be entitled to give such consent or to revoke any consent previously given
or to take any such action, whether or not such Persons continue to be Holders
after such record date, and for this purpose the Securities then outstanding
shall be computed as of such record date. No such consent shall become valid or
effective more than 120 days after such record date.

Section 9.5 Notation on or Exchange of Securities

     If an amendment or supplement changes the terms of a Security, the Trustee
may require the Holder of the Security to deliver it to the Trustee. The Trustee
may place an appropriate notation on the Security regarding the changed terms
and return it to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Security shall issue

                                       89
<PAGE>
and the Trustee shall authenticate a new Security that reflects the changed
terms, but the failure to make the appropriate notation or to issue a new
Security shall not affect the validity and effect of such amendment or
supplement.

Section 9.6 Trustee To Sign Amendments

     The Trustee shall sign any amendment or supplement authorized pursuant to
this Article IX if the amendment or supplement does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may but need not sign it. In signing such amendment or supplement the
Trustee shall be entitled to receive, and (subject to Section 7.1 hereof) shall
be fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel stating that the execution of such amendment or supplement is authorized
or permitted by this Indenture.

                              SUBSIDIARY GUARANTEE

Section 10.1 Subsidiary Guarantee

     Each Guarantor which is a party hereto or becomes a party hereto by
executing and delivering a supplement to this Indenture pursuant to Section 4.9
                                                                    -----------
hereof, jointly and severally, unconditionally Guarantees to each Holder and to
the Trustee and its successors and assigns the full and punctual payment of
principal of, premium (if any) and interest on the Securities when due, whether
at Stated Maturity, or upon optional redemption, required repurchase pursuant to
Section 4.7 or Section 4.11 hereof, acceleration or otherwise, and all other
-----------    ------------
monetary obligations owing by the Company under this Indenture (including
obligations owing to the Trustee) and the Securities (all the foregoing being
hereinafter collectively called the "Obligations"). The Guarantors further agree
that the Obligations may be extended or renewed, in whole or in part, without
notice or further assent from the Guarantors, and that the Guarantors will
remain bound under this Article X notwithstanding any extension or renewal of
                        ---------
any Obligation.

         The Guarantors waive presentation to, demand of, payment from and
protest to the Company of any of the Obligations and also waive notice of
protest for nonpayment. The Guarantors waive notice of any Default under the
Securities or the Obligations. The obligations of the Guarantors hereunder shall
not be affected by (i) the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any right or remedy against the Company or any
other Person under this Indenture, the Securities or any other agreement or
otherwise; (ii) any extension or renewal of any Obligation; (iii) any
rescission, waiver, amendment, modification or supplement of any of the terms or
provisions of this Indenture (other than this Article X), the Securities or any
                                              ---------
other agreement; (iv) the release of security, if any, held by any Holder or the
Trustee for the Obligations or any of them; (v) the failure of any Holder or the
Trustee to exercise any right or remedy against any other guarantor of the
Obligations; (vi) any change in the ownership of the Company, or (vii) any other
act or thing or omission or delay to do any other act or thing which may or
might in any manner or to any extent vary the risk of the Guarantors or would
otherwise operate as a discharge of the Guarantors as a matter of law or equity.

                                       90
<PAGE>

     The Guarantors, jointly and severally, further agree that their Subsidiary
Guarantees herein constitute a guarantee of payment when due (and not a
Subsidiary Guarantee of collection) and waive any right to require that any
resort be had by any Holder or the Trustee to security, if any, held for payment
of the Obligations.

     The obligations of the Guarantors hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason (except to the
extent provided in Section 10.2 hereof), including any claim of waiver, release,
                   ------------
surrender, alteration or compromise, and shall not be subject to any defense,
setoff, counterclaim, recoupment or termination whatsoever or by reason of the
invalidity, illegality or unenforceability of the Obligations or otherwise.

     The Guarantors, jointly and severally, further agree that their Subsidiary
Guarantees herein shall continue to be effective or be reinstated, as the case
may be, if at any time payment, or any part thereof, of any Obligation is
rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise.

     In furtherance of the foregoing and not in limitation of any other right
which any Holder or the Trustee has at law or in equity against the Guarantors
by virtue hereof, upon the failure of the Company to pay any Obligation when and
as the same shall become due, whether at Stated Maturity, upon optional
redemption, required repurchase, acceleration, redemption or otherwise, the
Guarantors hereby promise to and will, upon receipt of written demand by the
Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the
Trustee an amount equal to the sum of (i) the unpaid principal amount of such
Obligations, (ii) accrued and unpaid interest on such Obligations (but only to
the extent not prohibited by law) and (iii) all other monetary Obligations of
the Company to the Holders and the Trustee.

     The Guarantors, jointly and severally, agree that, as between the
Guarantors, on the one hand, and the Holders and the Trustee, on the other hand,
(x) the maturity of the Obligations guaranteed hereby may be accelerated as
provided in Article VI for the purposes of the Subsidiary Guarantee herein,
            ----------
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations guaranteed hereby, and (y) in the
event of any declaration of acceleration of such Obligations as provided in
Article VI, such Obligations (whether or not due and payable) shall forthwith
----------
become due and payable by the Guarantors for the purposes of this Section 10.1.
                                                                  ------------

     The Guarantors, jointly and severally, also agree to pay any and all costs
and expenses (including reasonable attorneys' fees) incurred by the Trustee or
any Holder in enforcing any rights under this Section 10.1.
                                              ------------

Section 10.2 Limitation on Liability

     Each Guarantor, and by its acceptance of Securities, each Holder, hereby
confirms that it is the intention of all such parties that the Subsidiary
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 Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree
that the obligations of such Guarantor will be limited to the maximum amount
that will, after giving effect to such

                                       91
<PAGE>

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 X, result in the obligations of such Guarantor under its Subsidiary
Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.3 Execution and Delivery of Subsidiary Guarantee

     To evidence its Subsidiary Guarantee set forth in Section 10.1, each
                                                       ------------
Guarantor hereby agrees that a notation of such Subsidiary Guarantee
substantially in the form attached as Exhibit D hereto will be endorsed by
                                      ---------
manual or facsimile signature by an Officer of such Guarantor on each Security
authenticated and delivered by the Trustee and that this Indenture will be
executed on behalf of such Guarantor by one of its Officers by execution of the
signature page hereof or by execution of a supplemental indenture substantially
in form of Exhibit E hereof.
           ---------

     Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in
Section 10.1 will remain in full force and effect notwithstanding any failure to
------------
endorse on each Security a notation of such Subsidiary Guarantee. If an Officer
whose signature is on this Indenture or on the Subsidiary Guarantee no longer
holds that office at the time the Trustee authenticates the Security on which a
Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid
nevertheless.

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

     In the event that the Company or any of its Restricted Subsidiaries
acquires or creates another Restricted Subsidiary (other than Foreign
Subsidiaries) after the Issue Date, the Company will comply with the provisions
of Section 4.9 hereof.
   -----------

Section 10.4 Successors and Assigns

     Except as otherwise provided in Section 10.9 hereof, this Article X shall
                                     ------------              ---------
be binding upon the Guarantors and their successors and assigns and shall inure
to the benefit of the successors and assigns of the Trustee and the Holders and,
in the event of any transfer or assignment of rights in accordance with the
terms of this Indenture by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Securities shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Indenture, the Securities and the
Subsidiary Guarantees.

Section 10.5 No Waiver

     Neither a failure nor a delay on the part of either the Trustee or the
Holders in exercising any right, power or privilege under this Article X shall
                                                               ---------
operate as a waiver thereof, nor shall a single or partial exercise thereof
preclude any other or further exercise of any right, power or privilege. The
rights, remedies and benefits of the Trustee and the Holders herein expressly
specified are cumulative and not exclusive of any other rights, remedies or
benefits which either may have under this Article X at law, in equity, by
statute or otherwise.

Section 10.6 Right of Contribution

     Each Guarantor hereby agrees that to the extent that a Guarantor shall have
paid more than its proportionate share of any payment made hereunder, such
Guarantor shall be entitled to seek and receive contribution from and against
any other Guarantor hereunder who has not paid its proportionate share of such
payment. Each Guarantor's right of contribution shall be subject to the terms
and conditions of this Article X. The provisions of this Section 10.6 shall in
                       ---------
no respect limit the obligations and liabilities of any Guarantor to the Trustee
and the Holders and each Guarantor shall remain liable to the Trustee and the
Holders for the full amount guaranteed by such Guarantor hereunder.

Section 10.7 No Subrogation

         Notwithstanding any payment or payments made by any of the Guarantors
hereunder, no Guarantor shall be entitled to exercise any rights of subrogation
it may have to any of the rights of the Trustee or any Holder against the
Company or any other Guarantor or any collateral security or guarantee or right
of offset held by the Trustee or any Holder for the payment of the Obligations,
nor shall any Guarantor seek or be entitled to seek any contribution or
reimbursement from the Company or any other Guarantor in respect of payments
made by such Guarantor hereunder, until all amounts owing to the Trustee and the
Holders by the Company on account of the Obligations are paid in full. If any
amount shall be paid to any Guarantor on account of such subrogation rights at
any time when all of the Obligations shall not have been paid in full, such
amount shall be held by such Guarantor in trust for the Trustee and the Holders,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Trustee in the exact form received by
such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to
be applied against the Obligations.

Section 10.8      Modification

         No modification, amendment or waiver of any provision of this Article
X, nor the consent to any departure by the Guarantors therefrom, shall in any
event be effective unless the same shall be made in accordance with Article IX
hereof. No notice to or demand on the Guarantors in any case shall entitle the
Guarantors to any other or further notice or demand in the same, similar or
other circumstances.

Section 10.9 Merger,  Consolidation or Sale of Assets of a Guarantor; Release of
a Guarantor

(a)      The Company shall not permit a Guarantor to sell or otherwise dispose
         of all or substantially all of its assets, 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:

(1)      immediately after giving effect to that transaction, no Default or
         Event of Default shall have occurred and be continuing; and

                                       93

(2)      either:

(A)      the Person acquiring the property in any such sale or disposition or
         the Person formed by or surviving any such consolidation or merger
         assumes all the obligations of that Guarantor under its Subsidiary
         Guarantee pursuant to a supplemental indenture satisfactory to the
         Trustee; or

(B)      an amount equal to the Net Proceeds of such sale or other disposition
         is applied in accordance with Section 4.7 hereof.

(b)      The Subsidiary Guarantee of a Guarantor will be released in accordance
         with Section 10.9(c) hereof:

(1)      in connection with any sale or other disposition of all or
         substantially all of the assets of that Guarantor (including by way of
         merger or consolidation), other than to the Company or another
         Guarantor, if the Company applies the Net Proceeds of that sale or
         other disposition in accordance with Section 4.7 hereof;

(2)      in connection with any sale or other disposition of all of the Capital
         Stock of a Guarantor (including by way of merger or consolidation)
         other than to the Company or another Guarantor, if the Company applies
         the Net Proceeds of that sale or other disposition in accordance with
         Section 4.7 hereof; or

(3)      if the Company designates any Restricted Subsidiary that is a Guarantor
         as an Unrestricted Subsidiary in accordance with the provisions of this
         Indenture;

which release shall be evidenced by a supplemental indenture satisfactory to the
Trustee and the Company.

(c) In the case of either: (a) or (b) above, the Company shall have delivered to
the Trustee an Officers' Certificate and an Opinion of Counsel, each stating
that such consolidation, merger or sale or other disposition (in the case of
(a)) or release (in the case of (b)), and any supplemental indenture, comply
with this Indenture.

(d) Notwithstanding anything in this Section 10.9 to the contrary, a Subsidiary
Guarantor may consolidate with or merge into the Company or another Subsidiary
Guarantor, and may transfer, sell or dispose of all or substantially all its
assets to the Company or another Subsidiary Guarantor.

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

     1. Interest. KCS Energy, Inc., a Delaware corporation (the "Company"),
promises to pay interest on the principal amount of this Security at 7 1/8 % per
annum from April 1, 2004 until maturity. The Company will pay interest
semi-annually in arrears on April 1 and October 1 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 Securities 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 Security 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 October 1, 2004. The
Company will pay, to the extent lawful, interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium, if any, at the rate then in effect; it will pay, to the extent lawful,
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace periods) from time to time on demand at the same rate as on
overdue principal. 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 Securities
(except Defaulted Interest) to the Persons who are registered Holders of
Securities at the close of business on the March 15 or September 15 next
preceding the Interest Payment Date, even if such Securities are canceled after
such record date and on or before such Interest Payment Date, except as provided
in Section 2.11 of the Indenture with respect to Defaulted Interest. The
   ------------
Securities will be payable as to principal, premium, if any, and interest at the
office or agency of the Paying Agent maintained for such purpose within the
Borough of Manhattan, the City and State of New York, or, at the option of the
Company, payment of interest may be made by check mailed by such Paying Agent to
the Holders at their addresses set forth in the register of Holders; provided
that payment by such Paying Agent by wire transfer of immediately available
funds will be required with respect to principal of and interest, and premium,
if any, on all Global Securities and all other Securities, the Holders of which
hold at least $5,000,000 aggregate principal amount of the Securities and will
have provided wire transfer instructions to the Company and 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, The Bank of New York Trust
Company, N.A., will act as Paying Agent and Registrar. The Company may appoint
and change any Paying Agent or Registrar without notice to any Holder and the
Company or any of its Subsidiaries may act as Paying Agent or Registrar, all in
accordance with the Indenture.

     4. Indenture. The Company issued the Securities under an Indenture, dated
as of April 1, 2004 (the "Indenture"), among the Company, the Guarantors named
on the signature pages thereto and the Trustee. The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Securities 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 Security conflicts with the
express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling. The Securities are unsecured obligations of the
Company. The Company initially issued $175,000,000 aggregate principal amount of
Securities. The Company may issue Additional Securities under the Indenture
subsequent to April 1, 2004, subject to Section 4.3 of the Indenture; provided,
                                        -----------
however, in no event may the Company issue any Additional Securities if, as a
result of any such issuance, the aggregate principal amount of Securities
outstanding would exceed the maximum aggregate principal amount of Securities
permitted under the Existing Credit Facilities or any other Credit Facilities,
in each case as in effect on the date of such issuance.

     5. Optional Redemption.

     (a) On and after April 1, 2008 the Company may redeem all or a part of the
Securities, at any time or from time to time, upon not less than 30 nor more
than 60 days' notice mailed to each Holder of Securities at such Holder's
registered address, in amounts of $1,000 or an integral multiple of $1,000, at
the following Redemption Prices (expressed as percentages of the principal
amount) plus accrued and unpaid interest on the Securities, if any, to the
applicable Redemption Date (subject to the right of Holders of record on the
relevant regular record date to receive interest due on an Interest Payment Date
that is prior to the Redemption Date), if redeemed during the 12-month period
beginning April 1 of the years indicated:

                           Year                                       Percentage

2009................................................................   101.781%
2010 and thereafter.................................................   100.000%

     (b) On or prior to April 1, 2007, the Company may on one or more occasions
redeem up to an aggregate amount equal to 35% of the aggregate principal amount
of the Securities (including any Additional Securities) originally issued prior
to the Redemption Date under the Indenture at a Redemption Price of 107.125% of
the principal amount of the Securities, plus accrued and unpaid interest, if
any, to the Redemption Date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant Interest Payment
Date) with the Net Cash Proceeds of one or more Equity Offerings; provided that
(i) at least 65% in aggregate principal amount of the Securities (including any
Additional Securities) originally issued remains outstanding immediately after
the occurrence of such redemption (excluding Securities held by the Company and
its Subsidiaries) and (ii) each such redemption occurs within 90 days of the

     6. Denominations, Transfer, Exchange. The Securities are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Securities may be registered and Securities may be exchanged as
provided in the Indenture. The Registrar or 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 or similar
governmental charges required by law or permitted by the Indenture. The Company
need not exchange or register the transfer of any Security or portion of a
Security selected for redemption, except for the unredeemed portion of any
Security being redeemed in part. Also, the Company need not exchange or register
the transfer of any Securities for a period of 15 days before the day of any
selection of Securities to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

     If this is a Global Security, this Security represents the aggregate
principal amount of outstanding Securities from time to time endorsed hereon,
and the aggregate principal amount of outstanding Securities represented by this
Security may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions in accordance with the Indenture.

     7. Persons Deemed Owners. The registered Holder of a Security may be
treated as its owner for all purposes.

     8. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture and the Securities may be amended or supplemented with the written
consent of the Holders of at least a majority in outstanding principal amount of
the Securities, and any existing Default or compliance with any provision of the
Indenture or the Securities may be waived with the written consent of the
Holders of at least a majority in outstanding principal amount of the
Securities. Without the consent of any Holder of a Security, the Indenture or
the Securities may be amended or supplemented (i) to cure any ambiguity, defect
or inconsistency, (ii) to provide for uncertificated Securities in addition to
or in place of certificated Securities, (iii) to provide for the assumption of
the Company's or a Guarantor's obligations under the Indenture and the
Securities, (iv) to add or release Guarantors in compliance with the Indenture,
(v) to secure the Securities, (vi) to make any change that would provide any
additional rights or benefits to the Holders, (vii) to make any change that does
not adversely affect the legal rights of any Holder, (viii) to comply with any
requirement of the SEC in connection with qualifying the Indenture under the
Trust Indenture Act or maintaining such qualification, (ix) to provide for the
issuance of the Exchange Securities and (x) to provide for the issuance of
Additional Securities in accordance with the Indenture.

     9. Defaults. If an Event of Default shall occur and be continuing, the
principal of all the Securities may be declared due and payable in the manner
and with the effect provided in the Indenture.

     10. Defeasance. The Indenture contains provisions for defeasance of (i) the
entire indebtedness of the Company on this Security and (ii) certain restrictive
covenants and the related Events of Default, subject to compliance by the
Company with certain conditions set forth in the Indenture, which provisions

Purchasers, the Company agrees with the Initial Purchasers, for the benefit of
the Initial Purchasers and the holders of the Initial Securities (including,
without limitation, the Initial Purchasers), the Exchange Securities (as defined
below) and the Private Exchange Securities (as defined below) (collectively, the
"Holder" or "Holders"), as follows:

     1. Registered Exchange Offer. The Company shall, at its own cost, prepare
and, not later than 90 days after (or if the 90th day is not a business day, the
first business day thereafter) the date of original issue of the Initial
Securities (the "Issue Date"), file with the Securities and Exchange Commission
(the "Commission") a registration statement (the "Exchange Offer Registration
Statement") on an appropriate form under the Securities Act of 1933, as amended
(the "Securities Act"), with respect to a proposed offer (the "Registered
Exchange Offer") to the Holders of Transfer Restricted Securities (as defined in
Section 6(d) hereof), who are not prohibited by any law or policy of the
Commission from participating in the Registered Exchange Offer, to issue and
deliver to such Holders, in exchange for the Initial Securities, a like
aggregate principal amount of debt securities (the "Exchange Securities") of the
Company issued under the Indenture and identical in all material respects to the
Initial Securities (except for the transfer restrictions relating to the Initial
Securities and the provisions relating to the matters described in Section 6(d)
hereof) that would be registered under the Securities Act. The Company shall use
its reasonable best efforts to cause such Exchange Offer Registration Statement
to become effective under the Securities Act within 180 days (or if the 180th
day is not a business day, the first business day thereafter) after the Issue
Date and shall keep the Registered Exchange Offer open for not less than 20
business days (or longer, if required by applicable law) after the date notice
of the Registered Exchange Offer is mailed to the Holders (such period being
called the "Exchange Offer Registration Period").

     If the Company commences the Registered Exchange Offer, the Company will be
entitled to close the Registered Exchange Offer 30 days after the commencement
thereof provided that the Company has accepted all the Initial Securities
theretofore validly tendered, and not withdrawn, in accordance with the terms of
the Registered Exchange Offer.

                                       1

     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the
Exchange Securities in the ordinary course of such Holder's business and has no
arrangements with any person to participate in the distribution of the Exchange
Securities and is not prohibited by any law or policy of the Commission from
participating in the Registered Exchange Offer) to trade such Exchange
Securities from and after their receipt without any limitations or restrictions
under the Securities Act and without material restrictions under the securities
laws of the several states of the United States; provided, however, that the
Exchanging Dealers (as defined below) will be required to deliver a prospectus
in connection with resales of Exchange Securities.

     The Company acknowledges that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder which is a broker-dealer
electing to exchange Initial Securities, acquired for its own account as a
result of market making activities or other trading activities, for Exchange
Securities (an "Exchanging Dealer"), is required to deliver a prospectus
containing the information set forth in (a) Annex A hereto on the cover, (b)
                                            -------
Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of
-------
the Exchange Offer" section, and (c) Annex C hereto in the "Plan of
                                     -------
Distribution" section of such prospectus in connection with a sale of any such
Exchange Securities received by such Exchanging Dealer pursuant to the
Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell
Exchange Securities acquired in exchange for Initial Securities constituting any
portion of an unsold allotment is required to deliver a prospectus containing
the information required by Items 507 or 508 of Regulation S-K under the
Securities Act, as applicable, in connection with such sale.

     The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein, in order to permit such prospectus to be lawfully
delivered by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided, however, that
(i) in the case where such prospectus and any amendment or supplement thereto
must be delivered by an Exchanging Dealer or an Initial Purchaser, such period
shall be the lesser of 180 days and the date on which all Exchanging Dealers and
the Initial Purchasers have sold all Exchange Securities held by them (unless
such period is extended pursuant to Section 3(j) below) and (ii) the Company
shall make such prospectus and any amendment or supplement thereto, available to
any broker-dealer for use in connection with any resale of any Exchange
Securities for a period of not less than 180 days after the consummation of the
Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects (including the
existence of restrictions on transfer under the Securities Act and the
securities laws of the several states of the United States, but excluding
provisions relating to the matters described in Section 6 hereof) to the Initial
Securities (the "Private Exchange Securities"). The Initial Securities, the
Exchange Securities and the Private Exchange Securities are herein collectively
called the "Securities."

     In connection with the Registered Exchange Offer, the Company shall:

          (a) mail to each Holder a copy of the prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

          (b) keep the Registered Exchange Offer open for not less than 20
     business days (or longer, if required by applicable law) after the date
     notice thereof is mailed to the Holders;

          (c) utilize the services of a depositary for the Registered Exchange
     Offer with an address in the Borough of Manhattan, The City of New York,
     which may be the Trustee or an affiliate of the Trustee;

                                       2

<PAGE>

          (d) permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York time, on the last business day on which
     the Registered Exchange Offer shall remain open; and

          (e) otherwise comply with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (x) accept for exchange all the Securities validly tendered and not
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (y) deliver to the Trustee for cancellation all the Initial Securities
     so accepted for exchange; and

          (z) cause the Trustee to authenticate and deliver promptly to each
     Holder of the Initial Securities, Exchange Securities or Private Exchange
     Securities, as the case may be, equal in principal amount to the Initial
     Securities of such Holder so accepted for exchange.

     The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the Issue Date.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of its business, (ii) such Holder has no
arrangements or understanding with any person to participate in the distribution
of the Securities or the Exchange Securities within the meaning of the
Securities Act, (iii) such Holder is not an "affiliate," as defined in Rule 405
of the Securities Act, of the Company or if it is an affiliate, such Holder will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, (iv) if such Holder is not a
broker-dealer, that it is not engaged in, and does not intend to engage in, the
distribution of the Exchange Securities and (v) if such Holder is a
broker-dealer, that it will receive Exchange Securities for its own account in
exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure that
(i) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any supplement thereto comply in all
material respects with the Securities Act and the rules and regulations
thereunder, (ii) any Exchange Offer Registration Statement and any amendment
thereto do not, when they become effective, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and (iii) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
such prospectus, do not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

     2. Shelf Registration. If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within
220 days of the Issue Date, (iii) any Initial Purchaser so requests with respect
to the Initial Securities (or the Private Exchange Securities) not eligible to
be exchanged for Exchange Securities in the Registered Exchange Offer and held
by it following consummation of the Registered Exchange Offer or (iv) any Holder
(other than an Exchanging Dealer) is not eligible to participate in the
Registered Exchange Offer or, in the case of any Holder (other than an
Exchanging Dealer) that participates in

                                       3

<PAGE>

the Registered Exchange Offer, such Holder does not receive freely tradeable
Exchange Securities on the date of the exchange, the Company shall take the
following actions:

          (a) The Company shall, at its cost, as promptly as practicable (but in
     no event more than 30 days after so required or requested pursuant to this
     Section 2) file with the Commission and thereafter shall use its reasonable
     best efforts to cause to be declared effective a registration statement
     (the "Shelf Registration Statement" and, together with the Exchange Offer
     Registration Statement, a "Registration Statement") on an appropriate form
     under the Securities Act relating to the offer and sale of the Transfer
     Restricted Securities by the Holders thereof from time to time in
     accordance with the methods of distribution set forth in the Shelf
     Registration Statement and Rule 415 under the Securities Act (hereinafter,
     the "Shelf Registration") on or prior to the 180th day following the Issue
     Date in the case of clause (i) above and on or prior to the 90th day after
     the date on which the Shelf Registration Statement is required to be filed
     in the case of clauses (ii), (iii) and (iv) above; provided, however, that
     no Holder (other than an Initial Purchaser) shall be entitled to have the
     Securities held by it covered by such Shelf Registration Statement unless
     such Holder agrees in writing to be bound by all the provisions of this
     Agreement applicable to such Holder.

          (b) The Company shall use its reasonable best efforts to keep the
     Shelf Registration Statement continuously effective, in order to permit the
     prospectus included therein to be lawfully delivered by the Holders of the
     relevant Securities, for a period of two years (or for such longer period
     if extended pursuant to Section 3(j) below) from the date of its
     effectiveness or such shorter period that will terminate when all the
     Securities covered by the Shelf Registration Statement (i) have been sold
     pursuant thereto or (ii) are no longer restricted securities (as defined in
     Rule 144 under the Securities Act, or any successor rule thereof) (the
     "Shelf Registration Period"). The Company shall be deemed not to have used
     its reasonable best efforts to keep the Shelf Registration Statement
     effective during the Shelf Registration Period if it voluntarily takes any
     action that would result in Holders of Securities covered thereby not being
     able to offer and sell such Securities during that period, unless such
     action is required by applicable law.

          (c) Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause (i) the Shelf Registration Statement and
     any amendment thereto and any related prospectus and any supplement
     thereto, as of the effective date of the Shelf Registration Statement,
     amendment or supplement, to comply in all material respects with the
     Securities Act and the rules and regulations thereunder, (ii) the Shelf
     Registration Statement and any amendment thereto not to contain any untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary in order to make the statements therein not
     misleading and (iii) the prospectus related to the Shelf Registration
     Statement, and any supplement to such prospectus, not to include an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary in order to make the statements therein, in
     the light of the circumstances under which they were made, not misleading.

     3. Registration Procedures. In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any Registered
Exchange Offer contemplated by Section 1 hereof, the following provisions shall
apply:

          (a) The Company shall (i) furnish to each Initial Purchaser, prior to
     the filing thereof with the Commission, a copy of the Registration
     Statement and each amendment thereof and each supplement, if any, to the
     prospectus included therein and, in the event that an Initial Purchaser
     (with respect to any portion of an unsold allotment from the original
     offering) is participating in the Registered Exchange Offer or the Shelf
     Registration Statement, the Company shall use its reasonable best efforts
     to reflect in each such document, when so filed with the Commission, such
     comments as such Initial Purchaser reasonably may propose; (ii) include the
     information set forth in Annex A hereto on the cover, in Annex B hereto in
                              -------                         -------

     Offer" section and in Annex C hereto in the "Plan of Distribution" section
                           -------
     of the prospectus forming a part of the Exchange Offer Registration
     Statement and include the information set forth in Annex D hereto in the
                                                        -------
     Letter of Transmittal delivered pursuant to the Registered Exchange Offer;
     (iii) if requested by an Initial Purchaser, include the information
     required by Items 507 or 508 of Regulation S-K under the Securities Act, as
     applicable, in the prospectus forming a part of the Exchange Offer
     Registration Statement; (iv) include within the prospectus contained in the
     Exchange Offer Registration Statement a section entitled "Plan of
     Distribution," reasonably acceptable to the Initial Purchasers, which shall
     contain a summary statement of the positions taken or

     "underwriter" status of any broker-dealer that is the beneficial owner (as
     defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended
     (the "Exchange Act") of Exchange Securities received by such broker-dealer
     in the Registered Exchange Offer (a "Participating Broker-Dealer"), whether
     such positions or policies have been publicly disseminated by the staff of
     the Commission or such positions or policies, in the reasonable judgment of
     the Initial Purchasers based upon advice of counsel (which may be in-house
     counsel), represent the prevailing views of the staff of the Commission;
     and (v) in the case of a Shelf Registration Statement, include the names of
     the Holders, who propose to sell Securities pursuant to the Shelf
     Registration Statement, as selling securityholders; provided, however, that
     each such Holder shall have furnished to the Company on a timely basis such
     information regarding the Holder as the Company may require pursuant to
     Section 3(n) hereof.

          (b) The Company shall give written notice to the Initial Purchasers,
     the Holders of the Securities proposed to be sold under the Shelf
     Registration Statement and any Participating Broker-Dealer from whom the
     Company has received prior written notice that it will be a Participating
     Broker-Dealer in the Registered Exchange Offer (which notice pursuant to
     clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend
     the use of the prospectus until the requisite changes have been made):

               (i) when the Registration Statement or any amendment thereto has
          been filed with the Commission and when the Registration Statement or
          any post-effective amendment thereto has become effective;

               (ii) of any request by the Commission for amendments or
          supplements to the Registration Statement or the prospectus included
          therein or for additional information;

               (iii) of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

               (iv) of the receipt by the Company or its legal counsel of any
          notification with respect to the suspension of the qualification of
          the Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

               (v) of the happening of any event that requires the Company to
          make changes in the Registration Statement or the prospectus in order
          that the Registration Statement or the prospectus do not contain an
          untrue statement of a material fact nor omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein (in the case of the prospectus, in light of the circumstances
          under which they were made) not misleading.

               (c) The Company shall make every reasonable effort to obtain the
          withdrawal at the earliest possible time, of any order suspending the
          effectiveness of the Registration Statement.

               (d) The Company shall furnish to each Holder of Securities
          included within the coverage of the Shelf Registration, without
          charge, at least one copy of the Shelf Registration Statement and any
          post-effective amendment thereto, including financial statements and
          schedules, and, if the Holder so requests in writing, all exhibits
          thereto (including those, if any, incorporated by reference).

               (e) The Company shall deliver to each Exchanging Dealer and each
          Initial Purchaser, and to any other Holder who so requests, without
          charge, at least one copy of the Exchange Offer Registration Statement
          and any post-effective amendment thereto, including financial
          statements and schedules, and, if any Initial Purchaser or any such
          Holder requests, all exhibits thereto (including those incorporated by
          reference).

               (f) The Company shall, during the Shelf Registration Period,
          deliver to each Holder of Securities included within the coverage of
          the Shelf Registration, without charge, as many copies of the
          prospectus (including each preliminary prospectus) included in the
          Shelf Registration Statement and any amendment or supplement thereto
          as such person may reasonably request. The Company consents, subject
          to the provisions of this Agreement, to the use of the prospectus or
          any amendment or supplement thereto by each

                                       5
<PAGE>

          of the selling Holders of the Securities in connection with the
          offering and sale of the Securities covered by the prospectus, or any
          amendment or supplement thereto, included in the Shelf Registration
          Statement.

               (g) The Company shall deliver to each Initial Purchaser, any
          Exchanging Dealer, any Participating Broker-Dealer and such other
          persons required to deliver a prospectus following the Registered
          Exchange Offer, without charge, as many copies of the final prospectus
          included in the Exchange Offer Registration Statement and any
          amendment or supplement thereto as such persons may reasonably
          request. The Company consents, subject to the provisions of this
          Agreement, to the use of the prospectus or any amendment or supplement
          thereto by any Initial Purchaser, if necessary, any Participating
          Broker-Dealer and such other persons required to deliver a prospectus
          following the Registered Exchange Offer in connection with the
          offering and sale of the Exchange Securities covered by the
          prospectus, or any amendment or supplement thereto, included in such
          Exchange Offer Registration Statement.

               (h) Prior to any public offering of the Securities, pursuant to
          any Registration Statement, the Company shall register or qualify or
          cooperate with the Holders of the Securities included therein and
          their respective counsel in connection with the registration or
          qualification of the Securities for offer and sale under the
          securities or "blue sky" laws of such states of the United States as
          any Holder of the Securities reasonably requests in writing and do any
          and all other acts or things reasonably necessary or advisable to
          enable the offer and sale in such jurisdictions of the Securities
          covered by such Registration Statement; provided, however, that the
          Company shall not be required to (i) qualify generally to do business
          in any jurisdiction where it is not then so qualified or (ii) take any
          action which would subject it to general service of process or to
          taxation in any jurisdiction where it is not then so subject.

               (i) The Company shall cooperate with the Holders of the
          Securities to facilitate the timely preparation and delivery of
          certificates representing the Securities to be sold pursuant to any
          Registration Statement free of any restrictive legends and in such
          denominations and registered in such names as the Holders may request
          a reasonable period of time prior to sales of the Securities pursuant
          to such Registration Statement.

               (j) Upon the occurrence of any event contemplated by clauses (ii)
          through (v) of Section 3(b) above during the period for which the
          Company is required to maintain an effective Registration Statement,
          the Company shall promptly prepare and file a post-effective amendment
          to the Registration Statement or a supplement to the related
          prospectus and any other required document so that, as thereafter
          delivered to Holders of the Securities or purchasers of Securities,
          the prospectus will not contain an untrue statement of a material fact
          or omit to state any material fact required to be stated therein or
          necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading. If the
          Company notifies the Initial Purchasers, the Holders of the Securities
          and any known Participating Broker-Dealer in accordance with clauses
          (ii) through (v) of Section 3(b) above to suspend the use of the
          prospectus until the requisite changes to the prospectus have been
          made, then the Initial Purchasers, the Holders of the Securities and
          any such Participating Broker-Dealers shall suspend use of such
          prospectus, and the period of effectiveness of the Shelf Registration
          Statement provided for in Section 2(b) above and the Exchange Offer
          Registration Statement provided for in Section 1 above shall each be
          extended by the number of days from and including the date of the
          giving of such notice to and including the date when the Initial
          Purchasers, the Holders of the Securities and any known Participating
          Broker-Dealer shall have received such amended or supplemented
          prospectus pursuant to this Section 3(j) or the Company shall have
          notified such Holders that disposition of such Transfer Restricted
          Securities may resume under the existing prospectus.

               (k) Not later than the effective date of the applicable
          Registration Statement, the Company will provide a CUSIP number for
          the Initial Securities, the Exchange Securities or the Private
          Exchange Securities, as the case may be, and provide the applicable
          trustee with printed certificates for the Initial Securities, the
          Exchange Securities or the Private Exchange Securities, as the case
          may be, in a form eligible for deposit with The Depository Trust
          Company.

               (l) The Company will comply with all rules and regulations of the
          Commission to the extent and so long as they are applicable to the
          Registered Exchange Offer or the Shelf Registration and will make
          generally available to its security holders (or otherwise provide in
          accordance with Section 11(a) of the Securities Act) an earnings
          statement satisfying the provisions of Section 11(a) of the Securities
          Act, no

                                       6
<PAGE>

          later than 45 days after the end of a 12-month period (or 90 days, if
          such period is a fiscal year) beginning with the first month of the
          Company's first fiscal quarter commencing after the effective date of
          the Registration Statement, which statement shall cover such 12-month
          period.

               (m) The Company shall cause the Indenture to be qualified under
          the Trust Indenture Act of 1939, as amended, in a timely manner and
          containing such changes, if any, as shall be necessary for such
          qualification. In the event that such qualification would require the
          appointment of a new trustee under the Indenture, the Company shall
          appoint a new trustee thereunder pursuant to the applicable provisions
          of the Indenture.

               (n) The Company may require each Holder of Securities to be sold
          pursuant to the Shelf Registration Statement to furnish to the Company
          such information regarding the Holder and the distribution of the
          Securities as the Company may from time to time reasonably require for
          inclusion in the Shelf Registration Statement, and the Company may
          exclude from such registration the Securities of any Holder that
          unreasonably fails to furnish such information within a reasonable
          time after receiving such request.

               (o) The Company shall enter into such customary agreements
          (including, if requested, an underwriting agreement in customary form)
          and take all such other action, if any, as any Holder of the
          Securities to be included in the Shelf Registration Statement shall
          reasonably request in order to facilitate the disposition of the
          Securities pursuant to any Shelf Registration.

               (p) In the case of any Shelf Registration, the Company shall (i)
          make reasonably available for inspection by the Holders of the
          Securities, any underwriter participating in any disposition pursuant
          to the Shelf Registration Statement and any attorney, accountant or
          other agent retained by the Holders of the Securities or any such
          underwriter all relevant financial and other records, pertinent
          corporate documents and properties of the Company and (ii) cause the
          Company's officers, directors, employees, accountants and auditors to
          supply all relevant information reasonably requested by the Holders of
          the Securities or any such underwriter, attorney, accountant or agent
          in connection with the Shelf Registration Statement, in each case, as
          shall be reasonably necessary to enable such persons, to conduct a
          reasonable investigation within the meaning of Section 11 of the
          Securities Act; provided, however, that the foregoing inspection and
          information gathering shall be coordinated on behalf of the Initial
          Purchasers by you and on behalf of the other parties, by one counsel
          designated by and on behalf of such other parties as described in
          Section 4 hereof; provided further, however, that any information that
          is designated in writing by the Company, in good faith, as
          confidential at the time of delivery of such information shall be kept
          confidential by the Holders or any such underwriter, attorney,
          accountant or other agent, unless such disclosure is made in
          connection with a court proceeding or required by law, or such
          information is or becomes available to the public generally or through
          a third party without, to the knowledge of any recipient of
          confidential information, an accompanying obligation of
          confidentiality or is independently developed.

               (q) In the case of any Shelf Registration, the Company, if
          requested by any Holder of the Securities covered thereby, shall cause
          (i) its counsel to deliver an opinion and updates thereof relating to
          the Securities in customary form addressed to such Holders and the
          managing underwriters, if any, thereof and dated, in the case of the
          initial opinion, the effective date of such Shelf Registration
          Statement (it being agreed that the matters to be covered by such
          opinion shall include, without limitation, the due incorporation and
          good standing of the Company and its subsidiaries; the qualification
          of the Company and its subsidiaries to transact business as foreign
          corporations; the due authorization, execution and delivery of the
          relevant agreement of the type referred to in Section 3(o) hereof; the
          due authorization, execution, authentication and issuance, and the
          validity and enforceability, of the applicable Securities; the absence
          of material legal or governmental proceedings involving the Company
          and its subsidiaries; the absence of governmental approvals required
          to be obtained in connection with the Shelf Registration Statement,
          the offering and sale of the applicable Securities, or any agreement
          of the type referred to in Section 3(o) hereof; the compliance as to
          form of such Shelf Registration Statement and any documents
          incorporated by reference therein and of the Indenture with the
          requirements of the Securities Act and the Trust Indenture Act,
          respectively; and, as of the date of the opinion and as of the
          effective date of the Shelf Registration Statement or most recent
          post-effective amendment thereto, as the case may be, the absence from
          such Shelf Registration Statement and the prospectus included therein,
          as then amended or supplemented, and from any documents incorporated
          by reference therein of an untrue statement of a material fact or the
          omission to

                                       7
<PAGE>

          state therein a material fact required to be stated therein or
          necessary to make the statements therein not misleading (in the case
          of any such documents, in the light of the circumstances existing at
          the time that such documents were filed with the Commission under the
          Exchange Act)); (ii) its officers to execute and deliver all customary
          documents and certificates and updates thereof requested by any
          underwriters of the applicable Securities and (iii) its independent
          public accountants to provide to the selling Holders of the applicable
          Securities and any underwriter therefor a comfort letter in customary
          form and covering matters of the type customarily covered in comfort
          letters in connection with primary underwritten offerings, subject to
          receipt of appropriate documentation as contemplated, and only if
          permitted, by Statement of Auditing Standards No. 72.

               (r) In the case of the Registered Exchange Offer, if requested by
          any Initial Purchaser or any known Participating Broker-Dealer, the
          Company shall cause (i) its counsel to deliver to such Initial
          Purchaser or such Participating Broker-Dealer a signed opinion in the
          form set forth in Section 6(c) of the Purchase Agreement with such
          changes as are customary in connection with the preparation of a
          Registration Statement and (ii) its independent public accountants to
          deliver to such Initial Purchaser or such Participating Broker-Dealer
          a comfort letter, in customary form, meeting the requirements as to
          the substance thereof as set forth in Section 6(a) and (f) of the
          Purchase Agreement, with appropriate date changes.

               (s) If a Registered Exchange Offer or a Private Exchange is to be
          consummated, upon delivery of the Initial Securities by Holders to the
          Company (or to such other person as directed by the Company) in
          exchange for the Exchange Securities or the Private Exchange
          Securities, as the case may be, the Company shall mark, or cause to be
          marked, on the Initial Securities so exchanged that such Initial
          Securities are being canceled in exchange for the Exchange Securities
          or the Private Exchange Securities, as the case may be; in no event
          shall the Initial Securities be marked as paid or otherwise satisfied.

               (t) The Company will use its reasonable best efforts to (a) if
          the Initial Securities have been rated prior to the initial sale of
          such Initial Securities, confirm such ratings will apply to the
          Securities covered by a Registration Statement, or (b) if the Initial
          Securities were not previously rated, cause the Securities covered by
          a Registration Statement to be rated with the appropriate rating
          agencies, but in each case only if so requested by Holders of a
          majority in aggregate principal amount of Securities covered by such
          Registration Statement, or by the managing underwriters, if any.

               (u) In the event that any broker-dealer registered under the
          Exchange Act shall underwrite any Securities or participate as a
          member of an underwriting syndicate or selling group or "assist in the
          distribution" (within the meaning of the Conduct Rules (the "Rules")
          of the National Association of Securities Dealers, Inc. ("NASD"))
          thereof, whether as a Holder of such Securities or as an underwriter,
          a placement or sales agent or a broker or dealer in respect thereof,
          or otherwise, the Company will assist such broker-dealer in complying
          with the requirements of such Rules, including, without limitation, by
          (i) if such Rules, including Rule 2720, shall so require, engaging a
          "qualified independent underwriter" (as defined in Rule 2720) to
          participate in the preparation of the Registration Statement relating
          to such Securities, to exercise usual standards of due diligence in
          respect thereto and, if any portion of the offering contemplated by
          such Registration Statement is an underwritten offering or is made
          through a placement or sales agent, to recommend the yield of such
          Securities, (ii) indemnifying any such qualified independent
          underwriter to the extent of the indemnification of underwriters
          provided in Section 5 hereof and (iii) providing such information to
          such broker-dealer as may be required in order for such broker-dealer
          to comply with the requirements of the Rules.

               (v) The Company shall use its reasonable best efforts to take all
          other steps necessary to effect the registration of the Securities
          covered by a Registration Statement contemplated hereby.

     4. Registration Expenses. The Company shall bear all fees and expenses
incurred in connection with the performance of its obligations under Sections 1
through 3 hereof (including the reasonable fees and expenses, if any, of counsel
for the Initial Purchasers incurred in connection with the Registered Exchange
Offer, other than the fees and expenses relating to compliance with state
securities or blue sky laws), whether or not the Registered Exchange Offer or a
Shelf Registration is filed or becomes effective, and, in the event of a Shelf
Registration, shall bear or reimburse the Holders of the Securities covered
thereby for the reasonable fees and disbursements of one firm of

                                       8
<PAGE>

counsel designated by the Holders of a majority in principal amount of the
Initial Securities covered thereby to act as counsel for the Holders of the
Initial Securities in connection therewith. Each Holder shall be responsible for
paying all underwriting discounts and commissions, if any, relating to the sale
or disposition of such Holder's Securities pursuant to a Shelf Registration
Statement.

          5. Indemnification.

          (a) The Company and each of the Guarantors, jointly and severally,
     agree to indemnify and hold harmless each Holder of the Securities, any
     Participating Broker-Dealer and each person, if any, who controls such
     Holder or such Participating Broker-Dealer within the meaning of the
     Securities Act or the Exchange Act (each Holder, any Participating
     Broker-Dealer and such controlling persons are referred to collectively as
     the "Indemnified Parties") from and against any losses, claims, damages or
     liabilities, joint or several, or any actions in respect thereof
     (including, but not limited to, any losses, claims, damages, liabilities or
     actions relating to purchases and sales of the Securities) to which each
     Indemnified Party may become subject under the Securities Act, the Exchange
     Act or otherwise, insofar as such losses, claims, damages, liabilities or
     actions arise out of or are based upon any untrue statement or alleged
     untrue statement of a material fact contained in a Registration Statement
     or prospectus or in any amendment or supplement thereto or in any
     preliminary prospectus relating to a Shelf Registration, or arise out of,
     or are based upon, the omission or alleged omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, and shall reimburse, as incurred, the
     Indemnified Parties for any legal or other expenses reasonably incurred by
     them in connection with investigating or defending any such loss, claim,
     damage, liability or action in respect thereof; provided, however, that (i)
     the Company and each Guarantor will not be liable in any such case to the
     extent that such loss, claim, damage or liability arises out of or is based
     upon any untrue statement or alleged untrue statement or omission or
     alleged omission made in a Registration Statement or prospectus or in any
     amendment or supplement thereto or in any preliminary prospectus relating
     to a Shelf Registration in reliance upon and in conformity with written
     information pertaining to such Holder and furnished to the Company by or on
     behalf of such Holder specifically for inclusion therein and (ii) with
     respect to any untrue statement or omission or alleged untrue statement or
     omission of a material fact made in any preliminary prospectus relating to
     a Shelf Registration Statement, the indemnity agreement contained in this
     subsection (a) shall not inure to the benefit of any Holder or
     Participating Broker-Dealer from whom the person asserting any such losses,
     claims, damages or liabilities purchased the Securities concerned, to the
     extent that a prospectus relating to such Securities was required to be
     delivered by such Holder or Participating Broker-Dealer under the
     Securities Act in connection with such purchase and any such loss, claim,
     damage or liability of such Holder or Participating Broker-Dealer results
     from the fact that there was not sent or given to such person, at or prior
     to the written confirmation of the sale of such Securities to such person,
     a copy of the final prospectus if the Company had previously furnished
     sufficient copies thereof to such Holder or Participating Broker-Dealer to
     permit delivery of the final prospectus on a timely basis by such Holder or
     Participating Broker-Dealer; provided further, however, that this indemnity
     agreement will be in addition to any liability which the Company and each
     of the Guarantors may otherwise have to such Indemnified Party. The Company
     and each of the Guarantors, jointly and severally, shall also indemnify
     underwriters, their officers and directors and each person who controls
     such underwriters within the meaning of the Securities Act or the Exchange
     Act to the same extent as provided above with respect to the
     indemnification of the Holders of the Securities if requested by such
     Holders.

          (b) Each Holder of the Securities, severally and not jointly, will
     indemnify and hold harmless the Company and each Guarantor, their directors
     and officers and each person, if any, who controls the Company or such
     Guarantor within the meaning of the Securities Act or the Exchange Act from
     and against any losses, claims, damages or liabilities or any actions in
     respect thereof, to which the Company or any such Guarantor, their
     directors and officers or any such controlling person may become subject
     under the Securities Act, the Exchange Act or otherwise, insofar as such
     losses, claims, damages, liabilities or actions arise out of or are based
     upon any untrue statement or alleged untrue statement of a material fact
     contained in a Registration Statement or prospectus or in any amendment or
     supplement thereto or in any preliminary prospectus relating to a Shelf
     Registration, or arise out of or are based upon the omission or the alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading, but in each case
     only to the extent that the untrue statement or omission or alleged untrue
     statement or omission was made in reliance upon and in conformity with
     written information

                                       9
<PAGE>

     pertaining to such Holder and furnished to the Company by or on behalf of
     such Holder specifically for inclusion therein; and, subject to the
     limitation set forth immediately preceding this clause, shall reimburse, as
     incurred, the Company or any such Guarantor, their directors and officers
     or any such controlling person for any legal or other expenses reasonably
     incurred by the Company or any such Guarantor, their directors and officers
     or any such controlling person in connection with investigating or
     defending any loss, claim, damage, liability or action in respect thereof.
     This indemnity agreement will be in addition to any liability that such
     Holder may otherwise have to the Company, any Guarantor, their directors
     and officers or any such controlling person.

          (c) Promptly after receipt by an indemnified party under this Section
     5 of notice of the commencement of any action or proceeding (including a
     governmental investigation), such indemnified party will, if a claim in
     respect thereof is to be made against the indemnifying party under this
     Section 5, notify the indemnifying party of the commencement thereof; but
     the failure to notify the indemnifying party shall not relieve the
     indemnifying party from any liability that it may have under subsection (a)
     or (b) above except to the extent that it has been materially prejudiced
     (through the forfeiture of substantive rights or defenses) by such failure;
     and provided further that the failure to notify the indemnifying party
     shall not relieve it from any liability that it may have to an indemnified
     party otherwise than under subsection (a) or (b) above. In case any such
     action is brought against any indemnified party, and it notifies the
     indemnifying party of the commencement thereof, the indemnifying party will
     be entitled to participate therein and, to the extent that it may wish,
     jointly with any other indemnifying party similarly notified, to assume the
     defense thereof, with counsel reasonably satisfactory to such indemnified
     party (who shall not, except with the consent of the indemnified party, be
     counsel to the indemnifying party), and after notice from the indemnifying
     party to such indemnified party of its election so to assume the defense
     thereof the indemnifying party will not be liable to such indemnified party
     under this Section 5 for any legal or other expenses, other than reasonable
     costs of investigation, subsequently incurred by such indemnified party in
     connection with the defense thereof. No indemnifying party shall, without
     the prior written consent of the indemnified party, effect any settlement
     of any pending or threatened action in respect of which any indemnified
     party is or could have been a party and indemnity could have been sought
     hereunder by such indemnified party unless such settlement (i) includes an
     unconditional release of such indemnified party from all liability on any
     claims that are the subject matter of such action, and (ii) does not
     include a statement as to or an admission of fault, culpability or a
     failure to act by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 5 is
     unavailable or insufficient to hold harmless an indemnified party under
     subsections (a) or (b) above, then each indemnifying party shall contribute
     to the amount paid or payable by such indemnified party as a result of the
     losses, claims, damages or liabilities (or actions in respect thereof)
     referred to in subsection (a) or (b) above (i) in such proportion as is
     appropriate to reflect the relative benefits received by the indemnifying
     party or parties on the one hand and the indemnified party on the other
     from the offering of the Initial Securities, pursuant to the Registered
     Exchange Offer, or (ii) if the allocation provided by the foregoing clause
     (i) is not permitted by applicable law, in such proportion as is
     appropriate to reflect not only the relative benefits referred to in clause
     (i) above but also the relative fault of the indemnifying party or parties
     on the one hand and the indemnified party on the other in connection with
     the statements or omissions that resulted in such losses, claims, damages
     or liabilities (or actions in respect thereof) as well as any other
     relevant equitable considerations. The relative fault of the parties shall
     be determined by reference to, among other things, whether the untrue or
     alleged untrue statement of a material fact or the omission or alleged
     omission to state a material fact relates to information supplied by the
     Company and the Guarantors on the one hand or such Holder or such other
     indemnified party, as the case may be, on the other, and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such statement or omission. The amount paid by an
     indemnified party as a result of the losses, claims, damages or liabilities
     referred to in the first sentence of this subsection (d) shall be deemed to
     include any legal or other expenses reasonably incurred by such indemnified
     party in connection with investigating or defending any action or claim
     which is the subject of this subsection (d). Notwithstanding any other
     provision of this Section 5(d), the Holders of the Securities shall not be
     required to contribute any amount in excess of the amount by which the net
     proceeds received by such Holders from the sale of the Securities pursuant
     to a Registration Statement exceeds the amount of damages which such
     Holders have otherwise been required to pay by reason of such untrue or
     alleged untrue statement or omission or alleged omission. No person guilty
     of fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Securities Act) shall be entitled to contribution from any person who

                                       10
<PAGE>

     was not guilty of such fraudulent misrepresentation. For purposes of this
     subsection (d), each person, if any, who controls such indemnified party
     within the meaning of the Securities Act or the Exchange Act shall have the
     same rights to contribution as such indemnified party and each person, if
     any, who controls the Company or any Guarantor within the meaning of the
     Securities Act or the Exchange Act shall have the same rights to
     contribution as the Company and the Guarantors.

          (e) The agreements contained in this Section 5 shall survive the sale
     of the Securities pursuant to a Registration Statement and shall remain in
     full force and effect, regardless of any termination or cancellation of
     this Agreement or any investigation made by or on behalf of any indemnified
     party.

     6. Additional Interest Under Certain Circumstances.

          (a) Additional interest (the "Additional Interest") with respect to
     the Initial Securities shall be assessed as follows if any of the following
     events occur (each such event in clauses (i) through (vi) below a
     "Registration Default"): (i) If an Exchange Offer Registration Statement is
     not filed with the Commission on or prior to the 90th day after the Issue
     Date;

               (ii) If an Exchange Offer Registration Statement or, if required
          pursuant to Section 2 above, a Shelf Registration Statement has not
          been declared effective by the Commission on or prior to the 180th day
          after the Issue Date;

               (iii) If the Registered Exchange Offer has not been consummated
          on or prior to the 40th day after the Exchange Offer Registration
          Statement is declared effective;

               (iv) If obligated to file the Shelf Registration Statement
          pursuant to pursuant to Section 2 above, the Company fails to file the
          Shelf Registration Statement with the Commission on or prior to the
          30th day after the date (the "Shelf Filing Date") on which the
          obligation to file a Shelf Registration Statement arises;

               (v) If obligated to file a Shelf Registration Statement pursuant
          to Section 2 above, the Shelf Registration Statement is not declared
          effective on or prior to the 90th day after the Shelf Filing Date; or

               (vi) If after either the Exchange Offer Registration Statement or
          the Shelf Registration Statement is declared effective (A) such
          Registration Statement thereafter ceases to be effective; or (B) such
          Registration Statement or the related prospectus ceases to be usable
          (except as permitted in subsection (b)) in connection with resales of
          Transfer Restricted Securities during the periods specified herein
          because either (1) any event occurs as a result of which the related
          prospectus forming part of such Registration Statement would include
          any untrue statement of a material fact or omit to state any material
          fact necessary to make the statements therein in the light of the
          circumstances under which they were made not misleading, or (2) it
          shall be necessary to amend such Registration Statement or supplement
          the related prospectus, to comply with the Securities Act or the
          Exchange Act or the respective rules thereunder.

               Additional Interest shall accrue on the Initial Securities over
          and above the interest set forth in the title of the Securities at a
          rate of 0.50% per year for the first 90-day period immediately
          following the occurrence of a Registration Default, and such rate will
          increase by an additional 0.50% per year with respect to each
          subsequent 90-day period until all Registration Defaults have been
          cured, up to a maximum Additional Interest rate of 1.50% per year.
          Such Additional Interest will be in addition to any other interest
          payable from time to time with respect to the Notes and the Exchange
          Securities. The Company will not be required to pay Additional
          Interest for more than one Registration Default at any given time.
          Following the cure of all Registration Defaults, the accrual of
          Additional Interest will cease and the interest rate will revert to
          the original rate.

               (b) A Registration Default referred to in Section 6(a)(vi)(B)
          hereof shall be deemed not to have occurred and be continuing in
          relation to a Shelf Registration Statement or the related prospectus
          if (i) such Registration Default has occurred solely as a result of
          (x) the filing of a post-effective amendment to such Shelf
          Registration Statement to incorporate annual audited financial
          information with respect to the Company where such post-effective
          amendment is not yet effective and needs to be declared effective to
          permit Holders to use the related prospectus or (y) other material
          events, with respect to the Company that would need to be described in
          such Shelf Registration Statement or the related prospectus and (ii)
          in the case of clause (y), the Company is proceeding promptly and in
          good faith to amend or supplement such Shelf Registration Statement
          and related prospectus to describe such events; provided, however,
          that in any case if such Registration Default occurs for a continuous
          period in excess of 60 days, Additional Interest shall be payable in
          accordance with the above paragraph from the day such Registration
          Default would have been deemed to occur but for this Section 6(b)
          until such Registration Default is cured.

               (c) Any amounts of Additional Interest due pursuant to Section
          6(a) above will be payable in cash on the regular interest payment
          dates with respect to the Initial Securities. The amount of Additional
          Interest will be determined by multiplying the applicable Additional
          Interest rate by the principal amount of the Initial Securities,
          multiplied by a fraction, the numerator of which is the number of days
          such Additional Interest rate was applicable during such period
          (determined on the basis of a 360-day year comprised of twelve 30-day
          months), and the denominator of which is 360.

               (d) "Transfer Restricted Securities" means each Security until
          (i) the date on which such Transfer Restricted Security has been
          exchanged by a person other than a broker-dealer for a freely
          transferable Exchange Security in the Registered Exchange Offer, (ii)
          following the exchange by a broker-dealer in the Registered Exchange
          Offer of an Initial Security for an Exchange Security, the date on
          which such Exchange Security is sold to a purchaser who receives from
          such broker-dealer on or prior to the date of such sale a copy of the
          prospectus contained in the Exchange Offer Registration Statement,
          (iii) the date on which such Initial Security has been effectively
          registered under the Securities Act and disposed of in accordance with
          the Shelf Registration Statement or (iv) the date on which such
          Initial Securities is distributed to the public pursuant to Rule 144
          under the Securities Act or is saleable pursuant to Rule 144(k) under
          the Securities Act.

               7. Rules 144 and 144A. The Company shall use its reasonable best
          efforts to file the reports required to be filed by it under the
          Securities Act and the Exchange Act in a timely manner and, if at any
          time the Company is not required to file such reports, it will, upon
          the request of any Holder of Initial Securities, make publicly
          available other information so long as necessary to permit sales of
          their securities pursuant to Rules 144 and 144A. The Company covenants
          that it will take such further action as any Holder of Initial
          Securities may reasonably request, all to the extent required from
          time to time to enable such Holder to sell Initial Securities without
          registration under the Securities Act within the limitation of the
          exemptions provided by Rules 144 and 144A (including the requirements
          of Rule 144A(d)(4)). The Company will provide a copy of this Agreement
          to prospective purchasers of Initial Securities identified to the
          Company by the Initial Purchasers upon request. Upon the request of
          any Holder of Initial Securities, the Company shall deliver to such
          Holder a written statement as to whether it has complied with such
          requirements. Notwithstanding the foregoing, nothing in this Section 7
          shall be deemed to require the Company to register any of its
          securities pursuant to the Exchange Act.

               8. Underwritten Registrations. If any of the Transfer Restricted
          Securities covered by any Shelf Registration are to be sold in an
          underwritten offering, the investment banker or investment bankers and
          manager or managers that will administer the offering will be selected
          by the Holders of a majority in aggregate principal amount of such
          Transfer Restricted Securities to be included in such offering.

               No person may participate in any underwritten registration
          hereunder unless such person (i) agrees to sell such person's Transfer
          Restricted Securities on the basis reasonably provided in any
          underwriting arrangements approved by the persons entitled hereunder
          to approve such arrangements and (ii) completes and executes all
          questionnaires, powers of attorney, indemnities, underwriting
          agreements and other documents reasonably required under the terms of
          such underwriting arrangements.

               9. Miscellaneous.

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Registered Exchange Offer must acknowledge that it will deliver
a prospectus in connection with any resale of such Exchange Securities. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Securities received in exchange for
Initial Securities where such Initial Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, for a period of 180 days after the
consummation of the Registered Exchange Offer, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution."

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Registered Exchange Offer must acknowledge that it will deliver
a prospectus in connection with any resale of such Exchange Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a
result of market-making activities or other trading activities. The Company has
agreed that, for a period of 180 days after the consummation of the Registered
Exchange Offer, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until , 200 (90 days after the consummation of the Registered Exchange
Offer), all dealers effecting transactions in the Exchange Securities may be
required to deliver a prospectus.

     The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers. Exchange Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities. Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     For a period of 180 days after the consummation of the Registered Exchange
Offer, the Company will promptly send additional copies of this Prospectus and
any amendment or supplement to this Prospectus to any broker-dealer that
requests such documents in the Letter of Transmittal. The Company has agreed to
pay all expenses incident to the Exchange Offer (including the expenses of one
counsel for the Holders of the Securities) other than commissions or concessions
of any brokers or dealers and will indemnify the Holders of the Securities
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.
